Advanced Diabetic Retinopathy Linked to Choroidal Thickening – MD Magazine

October 2nd, 2020 10:55 am

New technology could allow doctors new insight into the link between choroidal thickness and diabetic retinopathy (DR).

A team based in South Korea, led by Min Gyu Choi, Department of Ophthalmology, College of Medicine, Chung-Ang University Hospital, analyzed the effects of systemic and ocular profiles on subfoveal choroidal thickness (SFChT) in treatment-nave eyes with diabetic retinopathy.

In the retrospective, observational, cross-sectional study, the investigators examined 136 total eyes from 136 patients with diabetes and 30 eyes from 30 age-matched healthy controls between September 2016 and April 2018.

Only patients with treatment-nave eyes without any previous ocular treatment for diabetic retinopathy or diabetic macular edema were included in the study.

The ophthalmologic examination included the measurement of best-corrected visual acuity (BCVA), intraocular pressure (IOP), and refractive error; slit lamp examination; fundus examination and photography; and swept-source optical coherence tomography (SS-OCT).

For the regular systemic workup, the investigators examined body weight, height, body mass index (BMI), blood pressure (BP), complete blood cell count, hemoglobin A1c (HbA1c) level, liver function tests, and kidney function tests and analyzed microalbumin and creatinine levels in urine and the urinary (micro)albumin/creatinine ratio (ACR).

The study included only patients who underwent systemic workups within a span of 4 weeks of the ophthalmologic evaluations.

The investigators excluded patients with prior retinal surgery or panretinal photocoagulation (PRP), intravitreal injection, sub-Tenon's injection, history of ocular trauma or any other eye diseases (such as retinal and choroidal diseases), refractive error greater than 3.0 diopter (D), and systemic diseases besides diabetes or hypertension.

Using generalized linear model analyses, the investigators found that the SFChT in treatment-nave eyes positively associated with the diabetic retinopathy grade and estimated glomerular filtration rate (eGFR) (P = 0.001).

However, the study drug was negatively associated with age (P <0.001) and serum phosphorus levels (P = 0.001). Treatment-nave eyes with proliferative diabetic retinopathy(PDR; 313.4 9.0 m) or severe nonproliferative DR (NPDR; 299.7 9.7 m) had thicker choroid than eyes with mild to moderate NPDR (251.7 11.1 m) or no DR (231.2 14.5 m) after adjusting for age, eGFR, and phosphorus levels.

Choroid is affected by renal function and the grade of DR in patients with diabetes, the authors wrote. Advanced retinopathy is associated with choroidal thickening, and the severity of concomitant renal disease is associated with choroidal thinning.

Diabetic retinopathy is currently the leading of vision loss and blindness in both advanced and developing countries.

The use of enhanced-depth imaging optical coherence tomography allows investigators to view the choroidal thickness in patients with diabetic retinopathy.

Previously, the researchers found SFChT increases as the disease progresses in severity, while several other studies have suggested it decreases in patients with diabetes.

The study, Effects of Systemic Profiles on Choroidal Thickness in Treatment-Nave Eyes With Diabetic Retinopathy, was published online in Investigative Ophthalmology & Visual Science.

Coffee before breakfast could give you diabetes, experts warn – msnNOW

October 2nd, 2020 10:55 am

Provided by Daily Mail MailOnline logo

For millions of us, starting the day without a coffee doesnt bear thinking about.

But experts warn it is better to hold off from the caffeine hit until after breakfast because regularly drinking coffee beforehand may raise the risk of developing type 2 diabetes in the long term.

Researchers at the University of Bath asked 29 volunteers to drink a strong black coffee about an hour after getting up to understand how this would affect their blood sugar after breakfast.

After then having a sugary drink similar in calorie content to cereal or toast with jam their blood sugar was around 50 per cent higher than when they went without a coffee. The caffeine in the drink is thought to prevent muscles from absorbing the sugar.

This may not be an immediate problem, but frequently raised blood sugar over the years can lead to diabetes and heart disease, the study in the British Journal of Nutrition said.

Professor James Betts, senior author of the study, said: 'Nearly half of us will wake in the morning and, before doing anything else, drink coffee - intuitively the more tired we feel, the stronger the coffee.

'I love coffee too, and I'm not necessarily telling people to go without it, as it has some benefits.

Gallery: The Worst Things You Can Do for Your Health This Fall, According to Doctors (Best Life)

'Perhaps people should wait just a little while later, or until they get to work, so they don't have caffeine in their system when they eat a breakfast containing carbohydrates and sugar.'

Around 40 per cent of people in the UK are believed to drink a coffee as soon as they wake up.

Researchers wanted to see its effects in sleep-deprived people, so asked study participants to set an alarm to go off every hour during the night.

When they woke, to make sure they didn't fall asleep, researchers texted them questions such as simple sums every 30 seconds, to which they had to reply.

The study looked at people's blood sugar and insulin levels on three occasions - after a full night's sleep at home with no coffee, after broken sleep in their bed with no coffee, and after broken sleep and coffee.

This was 300mg of strong black coffee - about the equivalent of two standard cups.

Participants' blood sugar was tested following the breakfast drink, which they had around 30 minutes after the coffee.

The study, published in the British Journal of Nutrition, did not find coffee or sleep deprivation had an impact on insulin levels.

However, strong black coffee consumed before breakfast substantially increased the blood glucose response, repeated blood tests over two hours showed.

Professor Betts said: 'This study is important and has far-reaching health implications as up until now we have had limited knowledge about what coffee is doing to our bodies, in particular for our metabolic and blood sugar control.'

Diabetes and Weight Loss Linked to Increased Pancreatic Cancer Risk – Diabetes In Control

October 2nd, 2020 10:55 am

The case for expanding screening for pancreatic cancer in those with new onset of diabetes and weight loss.

Pancreatic cancer is a major cause of cancer-related deaths worldwide due to a lack of effective screening and resistance to chemotherapy. It is also difficult to diagnose during the early stages due to the lack of distinct symptoms. Symptoms associated with pancreatic cancer typically include weight loss, fatigue, jaundice, abdominal pain, and nausea and can be associated with many other conditions. The location of the pancreas also makes it difficult for physicians to see during routine physical exams. Therefore, diagnosis is generally made at advanced stages when it has already affected other organs such as the lungs, liver, and lymph nodes. Pancreatic cancer is commonly known as Pancreatic Ductal Adenocarcinoma. There is a 5-year survival rate in the United States. Unfortunately, no screening test has been shown to lower the risk of dying from this cancer. However, radiologists, gastroenterologists, surgeons, pathologists, and genetic counselors work together to find new tests to detect pancreatic cancer early. Currently, the most common tests used are endoscopic ultrasound or MRI.

A high body mass index or obesity has been associated with pancreatic cancer for many years. Diabetes, along with weight changes, has recently been associated with an increased risk of pancreatic cancer....

Sugar can cause headaches, and it’s more likely if you have diabetes – Insider – INSIDER

October 2nd, 2020 10:55 am

There are many different types of headaches, and your diet can play a role in how often you get them. In fact, your sugar consumption may be an important factor, especially if you have diabetes, as abnormal blood sugar levels are known to trigger headaches.

Eating too much or too little sugar can lead to headaches. This is because how much sugar you consume impacts your blood sugar levels. For example, eating too much sugar can cause your blood sugar to become too high, which is called hyperglycemia.

"With high blood sugar, small amounts of swelling can happen in and around blood vessels and surrounding brain tissue, which can cause headache," says Evan Barnathan, MD, a family physician at Central Maine Healthcare in Maine.

Additionally, high blood sugar is often accompanied by dehydration, which may trigger headaches.

On the other hand, eating too little sugar can cause blood sugar to become too low, which is known as hypoglycemia. When your blood sugar is too low, your body turns to alternate sources of energy from fat and protein, called ketones. The process is called ketosis, and it can lead to headaches, too.

For most healthy individuals, their bodies are able to regulate blood sugar levels and keep them within normal levels, even if they eat a big piece of cake. But those with diabetes aren't able to effectively regulate blood sugar, so what they eat will have a bigger impact.

As a result, people with poorly controlled diabetes will experience headaches from high or low blood sugar more often, says Barnathan. If you don't have diabetes, you're most likely to experience sugar-related headaches if you go on a sugar detox or start a no-carb diet like the Keto diet, because your body may start ketosis for energy after a few days.

Normal blood sugar levels are between 80 mg/dL and 130 mg/dL. When your blood sugar is higher or lower than that, it can cause headaches.

Hypoglycemia is when blood sugar levels are lower than 70 mg/dL. In addition to headaches, the symptoms of hypoglycemia can include:

If untreated, hypoglycemia can lead to more severe symptoms, like blurred vision and seizures.

Hyperglycemia is when your blood sugar is 130 mg/dL or higher before eating, or 180 mg/dL or higher two hours after eating. Other symptoms can include:

Barnathan says headaches will occur more often when blood sugar levels are above 200 mg/dL. For people with type 1 diabetes, hyperglycemia can lead to a dangerous condition called diabetic ketoacidosis (DKA), which can lead to coma or even death.

If you have a headache and you suspect it is from high blood sugar levels, make sure you are hydrated, says Barnathan. Your headache may be partly from the dehydration caused by hyperglycemia. You can also take an over-the-counter pain medicine like acetaminophen (Tylenol) or ibuprofen (Advil) to help relieve your headache.

If your headache is a result of hypoglycemia, it is usually because you haven't eaten, so eating a healthy meal will help. For example, eating small meals throughout the day full of whole grains, fiber, and lean protein can help avoid hypoglycemia.

If you have diabetes, make sure you always have a fast-acting carbohydrate with you, like juice or glucose tablets. These carbs can be quickly broken down into sugar, so you can raise your blood sugar fast before it drops dangerously low.

If you don't have diabetes, but recently cut sugar out of your diet and are experiencing headaches, make sure your body has complex carbs to break down for energy. That will help avoid ketosis and the accompanying headaches. Complex carbs include:

While anyone can experience a headache from eating too much or too little sugar, it is most common for people with diabetes.

It is important for diabetes patients to follow the treatment plan designed by their doctor in order to maintain healthy blood sugar levels, says Barnathan. This will help prevent headaches and other diabetes-related symptoms.

"If you're experiencing chronic headaches and you're worried this is due to poorly controlled diabetes, you should discuss this with your doctor," says Barnathan.

City of Hope Distinguished Scientist Debbie Thurmond Named New Director of Diabetes & Metabolism Research Institute – Business Wire

October 2nd, 2020 10:55 am

DUARTE, Calif.--(BUSINESS WIRE)--Leading diabetes scientist Debbie C. Thurmond, Ph.D., has been named the new director of City of Hopes Diabetes & Metabolism Research Institute, which continues diabetes research at City of Hope that was started more than 70 years ago. Arthur Riggs, Ph.D., who developed the technology in 1978 that resulted in the first synthetic human insulin, impacting millions of lives worldwide, will continue to conduct research within the institute.

Debbies depth of experience as a highly successful diabetes scientist and leader, as well as her vision for the DMRI, will lead us to continue to be one of the premier diabetes institutes in the nation, said Riggs, Samuel Rahbar Chair in Diabetes & Drug Discovery and director emeritus of Beckman Research Institute of City of Hope. A rising star in the diabetes field, Debbie will continue to be an excellent mentor to younger, independent scientists who, along with our senior scientists, are working on innovative diabetes research.

Thurmond joined City of Hope in 2015 as professor and founding chair of the Department of Molecular & Cellular Endocrinology within the Diabetes & Metabolism Research Institute. She became deputy director of the institute last year.

I am absolutely delighted and humbled to be named director of City of Hope's DMRI," said Thurmond, Ruth B. & Robert K. Lanman Chair in Gene Regulation & Drug Discovery Research. Art has built a phenomenal institute, and I have the great pleasure of facilitating its continued growth and prominence in the diabetes space.

In addition to leading the institutes support of ongoing diabetes research, Thurmond will support its focus on the intersection of diabetes and cancer, helping to answer the reasons why diabetes is significantly associated with an increase in cancer. As such, the institute recently established a new department the Department of Diabetes & Cancer Metabolism. The institute also provides endocrinology care to cancer patients, since type 2 diabetes significantly increases the risk of cancer. In addition, a growing number of highly effective cancer therapies can also cause insulin-dependent diabetes.

With the power of City of Hopes comprehensive cancer center alongside us, we are the only diabetes institute uniquely designed to focus on how to cure both diseases and to develop treatments to help prevent them, Thurmond added.

The Diabetes & Metabolism Research Institutes research in other initiatives includes cellular therapies to treat type 1 and type 2 diabetes; discovering new biomarkers to identify those at risk for developing type 2 diabetes and its complications; developing drugs that precisely target the receptor molecules responsible for diabetes; improving islet cell transplantation; and reviving and/or replacing the cells that make insulin.

The institute plans to open a clinical trial for the first type 1 diabetes vaccine tested in the U.S., part of The Wanek Family Project for Type 1 Diabetes, a $50 million initiative to find a cure for type 1 diabetes.

Thurmond and her teams research efforts include identifying cellular and molecular mechanisms in diabetes development and finding therapies to stop or reverse the diseases progression. One project focuses on boosting the bodys ability to create and preserve insulin-producing beta cells in order to maintain healthy blood sugar levels, as well as to boost muscle insulin responsiveness to combat prediabetes and type 2 diabetes.

Thurmonds work is supported by five research awards from the National Institutes of Health (NIH), the JDRF and Larry L. Hillblom Foundation. In fall 2018, Thurmond and her lab team were highlighted in an issue of the journal Diabetes for their discovery and identification of a new potential target that can keep the immune system stable and islet beta cells healthy, ultimately keeping type 1 diabetes in check. She was also awarded the prestigious John K. and Mary E. Davidson Lectureship and Award in the Department of Physiology at University of Toronto, Canada, in 2018, being the first female recipient in the history of the award.

Thurmond is also one of 21 accomplished female leaders, representing health organizations from across the U.S., awarded the Carol Emmott Fellowship in 2020. The fellowship expands the leadership capacity of women, who are already influential in their fields, so that they may increase their ability to make an impact and ultimately contribute to improving gender equity in health leadership through their own career advancement.

Prior to City of Hope, Thurmond was a professor of pediatrics and associate director of the Basic Diabetes Research Group within the Herman B. Wells Center for Pediatric Research at Indiana University School of Medicine, where she received the Trailblazer in Research Award in 2010.

Thurmond received her Ph.D. and postdoctoral training at University of Iowa, and her M.S. and B.S. degrees from University of California Davis. She serves on multiple editorial boards, including as associate editor for Frontiers in Endocrinology and a past associate editor of Diabetologia, as well as on national and international grant review panels, including as chair as one of the five NIH metabolism-focused grant review panels.

City of Hope has a long and impressive history of groundbreaking discoveries in the field of diabetes. It spans more than four decades of investigation since Rachmiel Levine, M.D., who discovered the role of insulin in glucose transport, launched diabetes research at City of Hope.

In 1978, Riggs and his colleagues synthesized human insulin from bacteria, a legendary scientific first. Synthetic human insulin was the first biologic approved by the U.S. Food and Drug Administration, and the product that launched the biotechnology industry. Decades later, millions of diabetes patients benefit from the daily medication they use to manage the disease. In another landmark contribution, Riggs led the team that developed the technology for creating monoclonal antibodies. Custom humanized antibodies produced using bacteria are behind numerous treatments addressing a host of conditions, including cancer and autoimmune conditions such as arthritis, multiple sclerosis and Crohns disease.

Heart to heart: Novo Nordisk teams with ACC to open diabetes discussion – FiercePharma

October 2nd, 2020 10:55 am

Novo Nordisk wants the heart disease community to join the diabetes conversation. As Type 2 diabetes drugs nab approvals for reduced cardiovascular risksincluding Novos own Ozempic and Victozathe need to communicate across specialties has grown.

To help bridge the gap, Novo Nordisk is partnering with the American College of Cardiology (ACC) in a two-year, two-pronged initiative. First, the partners will studyreal-world data to determine patterns and adherence to guidelines. Next, they'll explorehow to help Type 2 patients improve their heart health, workingthrough ACC clinicians and healthcare providers, Novo Chief Medical Officer Todd Hobbs said.

RELATED: Novo's Ozempic scores major win with heart-helping FDA approval. Is Rybelsus next?

Developing COVID-19 vaccines may not be enough: Turning vaccines into vaccinations

COVID-19 vaccines are being developed at a breakneck pace, but a broken supply chain could derail that momentum. What are the steps needed to help ensure the medical supply chain is up to the task?

The effort is a natural progression of Novo Nordisks relationships built up in the cardiovascular community over the past several years, he said.

Weve looked at smaller cuts of research, like with Cleveland Clinic and others, that show theres a lot of people out there with diabetes who really should be on one of the agents, either GLP-1 or SGLT2, that are proven to lower (cardiovascular) risk, and they just arent, Hobbs said.

While not an explicitpart of the study, COVID-19 has magnified the risks for people with diabetes and with heart disease. The partnership was in the works before the pandemic, but the novel coronavirus has made the initiative even more timely and relevant, Hobbs said.

The first part of the workevaluating data assessing adherence to ACC guidelines among a cohort of people with CV diseasewill be done within a year. The second stage will roll out specific treatment strategies to selected regional practices and hospitals, delivered through ACC healthcare ambassadors.

RELATED: Novo shifts Victoza ad message with spots highlighting heart-benefit trifecta

In January, Novo's next-gen GLP-1 drug Ozempic won an FDA toadd CV risk-reduction language to its label, specifying the benefits for patients with Type 2 diabetes andestablished cardiovascular disease.

Ozempic launched in early 2018 and took off quickly, nabbing $1.64 billion in 2019 sales. It's expected to reach $2.64 billion this year.

Novos newly launched Rybelsus, the oral version of Ozempic, is currently being studied as a CV preventive for patients with Type 2 diabetes. The company'solder GLP-1 diabetes med Victoza got a similar CV approval from the FDA in 2017 to add that it reduces the risk of heart attack, stroke and cardiovascular death.

While the ACC partnershipdoesnt includeany specific products, Hobbs said, If we can highlight the guidelines, whether thats ACC or ADA treatment guidelines, then our products will do well because theyre on the data.

Diabetes raises the risk of liver damage in people with HIV – aidsmap

October 2nd, 2020 10:55 am

Almost half of people with HIV with unexplained liver enzyme elevations or other abnormal liver markers had NASH and a third had stage F3 or F4 fibrosis, and advanced liver damage was strongly associated with type 2 diabetes, a four-country study reports in Clinical Infectious Diseases.

Fatty liver disease occurs when fat builds up in the liver. Greater fat accumulation can lead to non-alcoholic steatosis (NASH), in which liver cells balloon and become inflamed. Unchecked, NASH leads to scarring of liver tissue (fibrosis) and eventually to cirrhosis, in which normal liver functions decline.

Although a high prevalence of non-alcoholic fatty liver disease (NAFLD) has been reported in people living with HIV, its unclear what proportion of these cases already have NASH or advanced fibrosis. The only way that these conditions can be diagnosed definitively is through liver biopsies (direct sampling of liver tissue).

Thickening and scarring of connective tissue. Often refers to fibrosis of the liver. See also cirrhosis, which is more severe scarring.

Non-alcoholic fatty liver disease (NAFLD) is a very common disorder and refers to a group of conditions where there is accumulation of excess fat in the liver of people who drink little or no alcohol. The most common form of NAFLD is a non-serious condition called fatty liver, by which fat accumulates in the liver cells. A small group of people with NAFLD may have a more serious condition named non-alcoholic steatohepatitis (NASH).

A procedure to remove a small sample of tissue so that it can be examined for signs of disease.

In NASH, fat accumulation is associated with liver cell inflammation and different degrees of scarring. NASH is a potentially serious condition that may lead to severe liver scarring and cirrhosis. It sometimes affects older people living with HIV.

A group of diseases characterized by high levels of blood sugar (glucose). Type 1 diabetes occurs when the body fails to produce insulin, which is a hormone that regulates blood sugar. Type 2 diabetes occurs when the body either does not produce enough insulin or does not use insulin normally (insulin resistance). Common symptoms of diabetes include frequent urination, unusual thirst and extreme hunger. Some antiretroviral drugs may increase the risk of type 2 diabetes.

To learn more about the frequency of NASH in people living with HIV, investigators at hospitals in the United Kingdom, Italy, Canada and the United States carried out a retrospective study of biopsy samples from 166 people with HIV who had been referred for investigation of unexplained increases in liver enzymes or other abnormalities in laboratory markers of liver disease between 2001 and 2019.

The analysis excluded people with hepatitis B or C, any active cancer, alcohol consumption above 21 units a week for men or 14 units for women, or any other cause of chronic liver disease.

Study participants had a median age of 48 years, 93% were male, 72% were white and the median duration of antiretroviral treatment was nine years. The median CD4 cell count was 638 cells/mm3. None had taken older nucleoside analogues associated with steatosis (stavudine, didanosine). The median body mass index was 29 kg/m2 (borderline obesity), 53% had high blood pressure and 25% had diabetes.

Biopsies showed that 63 of 116 people had NAFLD (54%) and 57 (49% of the entire cohort) had NASH. Thirty-six people (31%) had F3 stage fibrosis and three (2%) had F4 fibrosis (cirrhosis).

"Theinvestigators recommend consideration of liver biopsy as a screening tool in people with HIV who are obese, especially those with type 2 diabetes."

Multivariate analysis showed that after controlling for metabolic factors associated with NAFLD (model 1) or HIV-related factors (model 2), the only factor associated with NAFLD was higher body mass index (adjusted odds ratio 1.20 in both models, p=0.001).

Advanced fibrosis (F3 or above) was the only factor associated with type 2 diabetes in multivariate analysis (aOR 3.42, 95% CI 1.00-11.71) and this association was on the borderline of statistical significance (p=0.05).

Using biopsy results as a gold standard, investigators also assessed whether laboratory markers could accurately identify patients with advanced fibrosis. They found that both the FIB-4 and NAFLD Fibrosis scores performed poorly in identifying advanced fibrosis but showed good sensitivity (93%) in ruling out cases where the collagen proportionate area (CPA) was above 7.6%. CPA measures the percentage of liver tissue that is fibrotic and a level above 7.6% has been shown to predict long-term adverse liver disease outcomes.

The poor prognostic value of non-invasive markers for liver fibrosis in people living with HIV leads the investigators to recommend consideration of liver biopsy as a screening tool in people with HIV who are obese, especially those with type 2 diabetes.

However, they also note that 41% of people referred for biopsy did not have NAFLD. Their liver enzyme elevations remained unexplained but 15 of these 53 patients had advanced fibrosis (Ishak score 3 or above). The only factor associated with advanced fibrosis in those without NAFLD was time since HIV diagnosis (21 years vs 11.5 years, p= 0.005), even though age was similar between the two groups.

Pulse Biosciences Announces FDA IDE Approval and Initiation of Sebaceous Hyperplasia Study – BioSpace

October 2nd, 2020 10:53 am

Oct. 1, 2020 11:30 UTC

Completes First Procedures in CellFX System Specific Indication Study

HAYWARD, Calif.--(BUSINESS WIRE)--Pulse Biosciences, Inc. (Nasdaq: PLSE), a novel bioelectric medicine company progressing Nano-Pulse Stimulation (NPS) technology, today announced FDA Investigational Device Exemption (IDE) approval and initiation of a pivotal study to evaluate the treatment of sebaceous hyperplasia (SH) lesions using the CellFX System. The data generated from this study is intended to support a 510(k) submission to expand the indication for use of the CellFX System specifically to treat SH lesions.

Following IDE approval, several patients have been enrolled, with the first patient procedure completed on September 28, 2020. The multicenter prospective comparative study is intended to evaluate the safety and efficacy of procedures to clear facial SH lesions performed with the CellFX System versus those performed by electrodessication in a comparator group. Enrollment of 60 patients across five study sites is expected to be completed in approximately three months. All subjects will have up to two treatments and will be evaluated through the primary safety and efficacy endpoints at 60-days following their last treatment. The ClinicalTrials.gov Identifier for the study is NCT04539886.

We are pleased to have received FDA IDE approval and to have begun this important SH comparative study slightly ahead of the fourth quarter start we had previously communicated. Understanding the COVID-19 pandemic has increased the demand on FDA resources, we appreciate their attention throughout the IDE process. Barring delays in enrollment, we expect to conclude the study in the first quarter of 2021 and plan to quickly follow with a 510(k) submission for the corresponding specific indication. We have long viewed SH as a top addressable market priority for the CellFX System based on patient demand in clinics today and the CellFX Systems early demonstration of procedure effectiveness, said Darrin Uecker, President and CEO of Pulse Biosciences. As we have communicated previously, in parallel we are completing our GLP preclinical study in support of the initial CellFX System 510(k) submission for a general dermatologic indication. We remain on track to submit this 510(k) in the next several weeks.

About Sebaceous Hyperplasia

Sebaceous hyperplasia (SH) is a very common skin condition that presents as shiny, yellowish or white raised bumps, or lesions, that most frequently occur on the face and are often oily in appearance. SH lesions form on the skin surface when the sebaceous glands, which are located in the deeper layer of the skin, become enlarged and form bumps between 2 and 4 millimeters wide on the facial skin surface. These deeper sebaceous glands that cause the SH lesion are difficult to treat with current thermal technologies without damaging the skin surface.

Based on a 2019 survey1, dermatologists who specialize in aesthetic procedures see an average of over 40 patients per week with SH lesions and their surveyed aesthetic patients diagnosed with this common problem are highly motivated to seek treatment as a cash-paying procedure to improve the appearance of their facial skin. Yet the majority of these patients diagnosed with SH are untreated, likely due to limitations of existing treatments that either cannot reach the sebaceous gland or that damage the skin surface, making the skin appearance worse than prior to treatment. Given the profile of NPS technology as a new option to reach these sebaceous glands with more desirable cosmetic effects, in the same survey, 88% of these aesthetic dermatology specialists reported a clear interest in a new procedure to address SH lesions. Previously published clinical data by the Company demonstrated that over 90% of SH lesions were cleared or mostly cleared by 60 days post-NPS treatment.

Zebrafish Embryo Model Helps Understand the Workings of Nanoparticles in Blood – AZoNano

October 2nd, 2020 10:53 am

Written by AZoNanoOct 1 2020

When nanoparticles are injected into the bloodstream, for instance, to kill solid tumors, it is not known what exactly happens to them.

Now, with new results reported in the ACS Nano journal, scientists from Aarhus University are set to deal with this challenging query by using zebrafish embryos as a new research model in nanotoxicology and nanomedicine.

A wide range of nanoparticles are engineered for targeted drug delivery, but regrettably, just a few of the injected nanoparticles reach the site of target, such as solid tumors. The reason for this low targeting efficiency is frequently considered a black box and thus had not been investigated thoroughly for a number of years.

An international research group, headed by Yuya Hayashi from the Department of Molecular Biology and Genetics (MBG), Aarhus University, has now shown the beauty of zebrafish embryos in nano-bioimaging that can view dynamic interactions between nanoparticles and target cells in a living entity.

Currently, in association with scientists from Interdisciplinary Nanoscience Center (iNANO), Yuya aims to answer the unexplained mysteries in bionanosciencethe first one is the biological identity concept, which elucidates how cells detect nanoparticles via a corona of proteins surrounding each particle.

For the first time, this concept has now been demonstrated in a living organism through the use of zebrafish embryos, revealing what exactly occurs to nanoparticles when they are injected into the blood.

What the Cell Sees in Bionanoscience is one of the initial publications that have established how a protein corona develops around a nanoparticle and how this protein corona indicates the need for reconsidering the way one observes nanoparticles within a biological setting. From elaborate research made in the last several years, researchers have now understood that two opposing effects mostly play a role in the cellular uptake of nanoparticles.

Generally, the protein corona inhibits the surface of the nanoparticle from direct physical interactions with the cell membrane. But what if the protein corona sends a signal that activates a particular biological interaction with receptors positioned on the cell membrane? That is something the cell detects and therefore confers a biological identity to the nanoparticle.

Currently, the scientists from Aarhus University have thus given the first visual proof for the excellent influence of the protein corona with regard to the clearance of nanoparticles from the blood that involved adverse results in the zebrafish embryo model.

The researchers employed a species-mismatched source of proteins for the formation of corona to produce a non-self biological identity and traced the movement of nanoparticles traveling via the blood and to their final targetthat is, endolysosomes in the cell.

This showed an unexpectedly quick uptake and acidification of the nanoparticles by scavenger endothelial cells (functional counterpart to the liver sinusoidal endothelial cells in mammals) followed by pro-inflammatory stimulation of macrophages.

It sounds like a crazy idea to inject nanoparticles with proteins from another animal, but for example, biomolecule-inspired nanomedicines are tested in a mouse model without particular concerns for the species-mismatched combination.

Yuya Hayashi, Department of Molecular Biology and Genetics, Aarhus University

Hayashi continued, Or else some clever folks humanise the mouse to take care of the species compatibility problem. In fact, even at the cell culture level nanoparticles are still routinely tested following the tradition to use serum supplement derived from cows while knowing that nanoparticle-protein interactions are a key driver of cellular uptake.

What makes this kind of experiments rather challenging is to maximally retain the original protein corona in a living organism. If the pre-formed corona gets quickly exchanged by endogenous blood proteins, the hypothesis tested becomes invalid. We have made quite some efforts to characterise the protein corona to ensure the nanoparticles preserve the non-self-biological identity.

Hossein Mohammad-Beigi, Study First Author, Aarhus University

The maximum benefit of the zebrafish model is its power in multicolor immediate imaging, whereby numerous combinations of reporter proteins and fluorescence tracers can be viewed in a basic arrangement at high spatio-temporal resolution. This offers a new chance that lies between less lifelike cell culture systems and more complex rodent experiments, like intravital microscopy.

Using cell cultures, we have learnt quite a lot about how cells recognise nanoparticles rather as dynamic aggregates of proteins but it was never tested in a more realistic situation. With establishment of the zebrafish model, we have finally acquired a means to further explore this question in a living organism.

Yuya Hayashi, Department of Molecular Biology and Genetics, Aarhus University

It was a simple approach with an extreme scenario tested in a very complex system, but I believe we are now one step closer to understanding what the protein corona can really mean to nanoparticles. In an environment rich in proteins, nanoparticles can wear a mask that gives them a biological identity, and its non-selfness can make them a foe. What defines the degree of the non-selfness? Well, it's the next big question we have to address, Hayashi concluded.

Mild to severe: Immune system holds clues to virus reaction – ABC News

September 30th, 2020 4:51 pm

One of COVID-19's scariest mysteries is why some people are mildly ill or have no symptoms and others rapidly die and scientists are starting to unravel why.

An international team of researchers found that in some people with severe COVID-19, the body goes rogue and attacks one of its own key immune defenses instead of fighting the coronavirus. Most were men, helping to explain why the virus is hitting men harder than women.

And separate research suggests that children fare better than adults thanks to robust first responder immune cells that wane with age.

They're the latest in a list of studies uncovering multiple features of the immune system's intricate cascade that can tip the scales between a good or bad outcome. Next up: Figuring out if all these new clues might offer much-needed ways to intervene.

We have the knowledge and capability of really boosting many aspects of the immune system. But we need to not use the sledge hammer, cautioned Dr. Betsy Herold of New York's Albert Einstein College of Medicine, who co-authored the child study.

Adding to the complexity, people's wildly varying reactions also reflect other factors, such as how healthy they were to begin with and how much of the virus the dose" they were exposed to.

Infection and what happens after infection is a very dynamic thing, said Alessandro Sette, a researcher at the La Jolla Institute for Immunology in San Diego, who is studying yet another piece of the immune response.

IMMUNE PRIMER

There are two main arms of the immune system. Innate immunity is the bodys first line of defense. As soon as the body detects a foreign intruder, key molecules, such as interferons and inflammation-causing cytokines, launch a wide-ranging attack.

Innate immune cells also alert the slower-acting adaptive arm of the immune system, the germ-specific sharpshooters, to gear up. B cells start producing virus-fighting antibodies, the proteins getting so much attention in the vaccine hunt.

But antibodies aren't the whole story. Adaptive immunity's many other ingredients include killer T cells that destroy virus-infected cells and memory T and B cells that remember an infection so they spring into action quicker if they encounter that germ again.

A MISSING PIECE

Usually when a virus invades a cell, proteins called Type I interferons spring into action, defending the cell by interfering with viral growth. But new research shows those crucial molecules were essentially absent in a subset of people with severe COVID-19.

An international project uncovered two reasons. In blood from nearly 1,000 severe COVID-19 patients, researchers found 1 in 10 had what are called auto-antibodies antibodies that mistakenly attack those needed virus fighters. Especially surprising, autoimmune disorders tend to be more common in women but 95% of these COVID-19 patients were men.

The researchers didn't find the damaging molecules in patients with mild or asymptomatic COVID-19.

In another 660 severely ill patients, the same team found 3.5% had gene mutations that didn't produce Type I interferons.

Each of those silent vulnerabilities was enough to tip the balance in favor of the virus early on, said Dr. Jean-Laurent Casanova, an infectious disease geneticist at Rockefeller University in New York, who co-leads the COVID Human Genetic Effort.

Certain interferons are used as medicines and are under study as a possible COVID-19 treatment; the auto-antibody discovery adds another factor to consider.

KIDS' IMMUNITY REVS FAST

It's not clear why children appear less at risk from COVID-19. But occasionally they're sick enough for hospitalization, giving Herold's team the opportunity to compare 60 adults and 65 children and teens at New Yorks Montefiore Health System.

The children produced much higher levels of certain cytokines that are among the innate immune system's first responders. When the immune system's next stage kicked in, both adults and children made antibodies targeting the coronavirus. Here's the rub: The adults' adaptive immune response was more the type that can trigger an inflammatory overreaction.

The findings suggest kids' early robust reaction lets their immune system get ahead of the virus, making an overreaction less likely "and that's protecting them, Herold said.

ANY PREEXISTING IMMUNITY?

The coronavirus that causes COVID-19 is new to humans. But Sette's team studied blood samples that were stored in freezers before the pandemic and found some harbored memory T cells that recognized a tiny portion of the new virus in laboratory tests.

You can actually tell that this is an experienced T cell. This has seen combat before, Sette said. Researchers in Germany, Britain and other countries have made similar findings.

The new coronavirus has cousins that cause as many as 30% of common colds, so researchers believe those T cells could be remnants from past colds.

But despite the speculation, we don't know yet that having those T cells makes any difference in who gets seriously sick with COVID-19, noted Rory de Vries, co-author of a study in the Netherlands that also found such T cells in old blood.

All these findings beg for a deeper understanding of the myriad ways some people can be more susceptible than others.

We need to look quite broadly and not jump into premature conclusions about any one particular facet of the immune system, said Stanford University immunologist Bali Pulendran. He also has found some innate immune cells in a state of hibernation in seriously ill adults and next is looking for differences before and after people get sick.

But, it's not just all about the immune system, cautioned Dr. Anita McElroy, a viral immunity expert at the University of Pittsburgh Medical Center whos closely watching the research. A way to tell in advance who's most at risk? Were a long, long way from that.

The immune system: How to boost it and lower your immune age – New Scientist News

September 30th, 2020 4:51 pm

Your immune system stands between you and deadly infections. But as you get older so does your immune age, making you more susceptible to disease. Fortunately, we are discovering plenty of things you can do to turn back the clock and stay healthy. In this episode of our video series Science with Sam, find out how your immune system works and how you can give it a boost.

Tune in every week toyoutube.com/newscientistfor a new episode, or check back tonewscientist.com

One of the most important things standing between you and a deadly infection is your immune system the intricate, biological defence mechanism that protects your body from harmful invaders. And theres a lot we can do to give our immune system a helping hand.

Your immune system is made up of two divisions: the innate immune system and the adaptive immune system, each with its own battalion of specialist cells and defensive weapons.

The innate immune system is the first line of defence. Its made up of cells like the scary-sounding macrophage, and the less scary-sounding neutrophil. These general-purpose guards patrol the bloodstream on the lookout for anything that shouldnt be there. When they detect an intruder, they neutralise the threat by engulfing it like Pac-Man, spraying it with deadly chemicals or suicidally expelling their DNA and throwing it around the invader like a net.

Then theres the adaptive immune system, which you can think of as the immune systems special forces, elite agents trained to fight specific pathogens. Unlike the innate system, which can attack any invading cell or virus, these cells are only effective against one enemy, and they must be trained to fight them first.

B cells fight bacteria and viruses by making Y-shaped proteins called antibodies that neutralise an invader or tag it for attack by other parts of the immune system.

Then there are T cells. These coordinate and carry out attacks on infected cells. Helper T Cells call in reinforcements by sending out chemical messages known as cytokines. Killer T-Cells are the front line soldiers, trained, as the name suggests, to destroy the enemy.

When we encounter a disease for the first time, it takes a while for the adaptive immune system to learn how to fight it. But once its up and running, it creates a memory, allowing a fast and brutal response to future infections often neutralising it before you even notice. This is the premise of vaccines and the reason why you only get diseases like chicken pox once.

If you want to know more about vaccines, theres a video all about them, just hit the link at the end of this video. Better yet, subscribe to New Scientist today and get 20 per cent off if you enter the code SAM20 at checkout.

Your immune system works so well that, most of the time, you wont even notice it. But it weakens as you get older, making you more susceptible to infection. Thats a key reason why people over the age of 70 are most vulnerable to diseases like covid-19, or even the flu.

This decline happens to all of us, but it can be accelerated by lifestyle factors like smoking and inactivity. Obesity is also linked to a faster decline in immune potency.

All of which means that, although the strength of your immune system is linked to your age, a 40-year-old can have the immune system of a 60-year-old. Or on the flipside, a healthy 60-year-old may have the immune system of a 40-year-old.

Scientists have recently developed ways to measure your immune age. Fortunately, it turns out your immune age can go down as well as up. And there are some simple ways to turn back the clock on your immune system.

As we get older, some of our immune cells start to misbehave. Take neutrophils, those early responder cells. As they age, they get worse at hunting down intruders, blundering through your tissues, causing damage.

The root of the problem is an overactive enzyme involved in their sense of direction. Dialling down that enzyme rejuvenates the neutrophils so they know where theyre going. And theres a simple, drug-free way to do it: exercise.

One study in older adults showed that those who got 10,000 steps a day on average had neutrophils as good as a young adult.

Exercise also has benefits for your T cells. Before they are released onto active duty, T-cells mature in a little-known organ called the thymus gland in your chest. The thymus degenerates over time, resulting in a drop-off in the number of T cells.

Physical activity has a huge effect on the rate of this degeneration. A study found that amateur cyclists aged between 55 and 79 had youthful thymus glands and their T-cell counts were similar to those of much younger people.

Another key factor in your immune age is your gut bacteria. There is good evidence that poor gut health is a cause of premature ageing and that a healthy microbiome can reduce your immune age. Eating a healthy, varied diet rich in fibre, plant matter and fermented foods can help maintain a healthy community of gut microbes.

Your body has a highly evolved, intricate defence system thats effective at keeping you well, but only if you look after it.

I dont know about you but Ive been a bit less active of late, so Im considering this something of a wake-up call.

Looking after your immune system is a no-brainer, and its as easy as a walk in the park.

Strong activation of anti-bacterial cells of immune system linked to severe Covid-19: Study – Hindustan Times

September 30th, 2020 4:51 pm

A type of the immune systems T cells known to fight against bacterial infections is strongly activated in people with moderate to severe Covid-19, according to a study which provides a better understanding of how the body responds to the novel coronavirus infection.

Researchers, including those from the Karolinska Institutet in Sweden, noted that this component of the immune system called MAIT cells make up about one to five percent of T cells in the blood of healthy people, and are primarily important for controlling bacteria, but can also be recruited to fight some viral infections.

They explained that T cells are a type of white blood cells that are specialised in recognizing infected cells, and are an essential part of the immune system. In the current study, published in the journal Science Immunology, the scientists assessed the role played by MAIT cells in Covid-19 disease.

They examined the presence and character of MAIT cells in blood samples from 24 patients admitted to Karolinska University Hospital with moderate to severe Covid-19 disease, and compared these with blood samples from 14 healthy controls and 45 individuals who had recovered from Covid-19. Four of the patients died in the hospital, the study noted.

To find potential treatments against Covid-19, it is important to understand in detail how our immune system reacts, and in some cases, perhaps contribute to worsening the disease, said Johan Sandberg, a co-author of the study at Karolinska Institutet.

According to the study, the number of MAIT cells in the blood decline sharply in patients with moderate or severe Covid-19, and the remaining cells in circulation are highly activated.

Based on these results, the scientists suggested that the MAIT cells are engaged in the immune response against the novel coronavirus SARS-CoV-2. This pattern of reduced number and activation in the blood is stronger for MAIT cells than for other T cells, they said. The study also noted that pro-inflammatory MAIT cells accumulated in the airways of Covid-19 patients to a larger degree than in healthy people.

Taken together, these analyses indicate that the reduced number of MAIT cells in the blood of Covid-19 patients is at least partly due increased accumulation in the airways, Sandberg said.

The scientists added that the number of MAIT cells in the blood of convalescent Covid-19 patients recovered at least partially in the weeks after disease, which can be important for managing bacterial infections in individuals who have had Covid-19. They said the MAIT cells tended to be extremely activated in the patients who died.

The findings of our study show that the MAIT cells are highly engaged in the immunological response against Covid-19, Sandberg said. The scientists believe the characteristics of MAIT cells make them engaged early on in both the systemic immune response, and in the local immune response in the airways to which they are recruited from the blood by inflammatory signals.

There, they are likely to contribute to the fast, innate immune response against the virus. In some people with Covid-19, the activation of MAIT cells becomes excessive and this correlates with severe disease, Sandberg added.

ETHZ-led group shows that nervous system directly influences immune system – Optics.org

September 30th, 2020 4:51 pm

29Sep2020

Optogenetics researchers in Switzerland and US have optically stimulated nerve fibers in living mice.

Through this process, they have demonstrated that the nervous system has a direct influence on the immune system.

Over the past ten years, a new method has literally shed more light on the brain: optogenetics allows scientists to dstimulate genetically-modified nerve cells and investigate their functioning within the complex network inside the skull. This technique represents a revolution in neuroscience, say the Swiss-US team, but to date, it could only be applied to study the central nervous system, and not the peripheral nervous system.

A team of electrical engineers led by Qiuting Huang, a professor at the Institute for Integrated Systems at ETH Zurich, have developed a system that connects implantable LEDs with a tiny device on the subjects head which can be controlled from a tablet via Bluetooth. They have stimulated, with great precision, nerve fibers in the bodies of freely-moving mice, as the scientists report in Nature Biotechnology.

Our goal was to develop an integrated platform as small as possible. Together, the chip, the battery and the antenna for wireless signal transmission weigh less than one gram and occupy less than one cubic centimetre, explained Huang.

While the chip technology enables high integration density of electronic circuits, there are limits to miniaturization, particularly with batteries; the smaller the volume, the greater the energy density. This, in turn, increases the risk that batteries might ignite.

The team originally intended to develop this platform for a project to measure oxygen saturation and blood pressure, but right from the outset of the design phase, they endeavored to ensure the widest possible application for the chip.

Because our system is programmable, we were able to take the electronic circuits that we had been intending to use to measure oxygen saturation in blood and re-purpose them to control the implanted light emitting diodes, said contributing scientist Philipp Schnle.

The group has been collaborating with Stphanie Lacours group at EPFL for five years. Our sophisticated electronics and their soft bioelectronic sensors were made for each other, said Huang. Advances in material sciences and electronics build on each other and interconnect with each other. Together, we have developed an approach that allows us to stimulate a specific nerve fiber in the body of the mouse at precise points in time, added Schnle.

At Harvard Medical School, a research group led by Clifford Woolf wrapped the implants around the sciatic nerve. Without damaging the nerve, over several days, they managed to repeatedly use blue light flashes to activate specific nerve cells known as the nociceptors, which specialize in the transmission of pain signals.

To their surprise, the researchers discovered that repeated optical stimulation of these nociceptors produced a slight reddening in one of the mouses hind paws, a clear sign of inflammation.

Scientists had previously assumed that pain and inflammation were two different processes that arose independently. But now we have been able to prove conclusively that the neurons responsible for pain sensations can also generate an inflammatory immune response, said Woolf. As the researchers explain in the Nature Biotechnology article, these results may potentially point the way to new approaches in such areas as the treatment of chronic pain, or persistent inflammation.

Huang believes that electrical engineering will play an increasingly important role in human health in the future. He highlights the term electroceuticals a combination of electronics and pharmaceuticals which is already being discussed among experts.

Agios helps identify genes that allow cancer to escape the immune system – FierceBiotech

September 30th, 2020 4:51 pm

Despite the availability of multiple FDA-approved immunotherapies that leverage the bodys immune system to fight cancer, only a fraction of cancer patients are benefiting. That's because cancer cells are cunning. They develop strategies to avoid being targeted and destroyed by immune cells.

To understand the genetic drivers behind the ability of cancer cells to evade the immune system, scientists at the University of Toronto, in collaboration with Agios Pharmaceuticals, used CRISPR to screen six genetically diverse mouse cancer cell lines. They found that genes involved in autophagya process where cells recycle damaged components to regenerate themselveswere key for immune evasion.

The researchers suggested that their findings, published in Nature, open up new venues for the development of immunotherapies that could be effective for largepatient populations across several different tumor types.

From Concept to Market: Overcoming the Challenges of Manufacturing and Clinical Trials

Learn how CRO/CDMOs successfully address operational and regulatory challenges for pharmaceutical and biotechnology clients; and how this can make the difference between study success or failure.

Its very important to understand at the molecular level how cancer develops resistance to immunotherapies in order to make them more broadly available, saidUniversity of Toronto professor Jason Moffat, Ph.D., the studys corresponding author, in a statement.

Moffat and colleagues used CRISPR to screen cancer cells that were cultured in the presence or absence of preactivated killer T cellsimmune cells with a natural ability to hunt and kill cancer. They identified 182 genes that, when deleted, increased either the sensitivity or theresistance of cancer cells to T cells. They called them core cancer-intrinsic cytotoxic T lymphocyte-evasion genes, becauseevery one of them was present across at least three of the six cells lines that the team screened.

The core set of genes included several genes that were known to affect signaling of interferon gamma, a cytokine thats critical to an array of immune responses and that serves as a master communicator with several types of immune cells. Three negative regulators of the interferon-gamma responseSocs1, Ptpn2 and Adaralso emerged as immune-evasion genes.

Several genes identified were related to autophagy. Among the top hits was the Fitm2 gene, which is required for normal fat storage in adipose tissue in mice but was not previously associated with interferon-gamma signaling.

RELATED:New strategies for improving pancreatic cancer treatments

In two mouse models of renal cell carcinoma and melanoma, cancer cells with deleted Fitm2 showed increased cell death after treatment with interferon gamma compared with control cells, the team reported.

Surprisingly, the researchers also found that deleting certain autophagy genes in pairs could make the cells resist T-cell killing. For example, cells that lacked both Atg12 and Atg5 were strongly resistant to the killing effects of T cells as compared with single-mutant cells. This means that if a tumor already harbors a mutation in one autophagy gene, an immunotherapy that targets another autophagy gene could make the disease worse, the researchers explained.

Other oncology researchers are also focusing on the autophagy. A team from the University of Cincinnati, for example, found that mutations in mitochondrial complex I could prevent the autophagy thats triggered by mTOR inhibitors. And researchers at the University of North Carolina reported that targeting the KRAS mutation in pancreatic cancer with an MEK inhibitor made cancer cells more dependent on autophagy for survival. They blocked the process with the anti-malaria drug hydroxychloroquine.

The University of Toronto-led team believes its list of 182 core immune-evasion genes may inform efforts to develop novel cancer immunotherapies. The scientists stressed the need to explorehow combined genetic interactions may alter cancers immune-evasion activity. While simultaneous control of certain genetic features may sensitize cancer cells to immunotherapy, it could make the disease worse in others, they warned.
