New Hep C Treatment Can Cure Most Patients
hepatitis C without interferon, with cure rates often exceeding 95%, according to a recently published review.
"Oral DAA regimens that are highly efficacious, well-tolerated, and relatively short in duration are now available for all [hepatitis C virus] genotypes and for patient populations historically considered difficult to cure," wrote Oluwaseun Falade-Nwulia, MBBS, MPH, from Johns Hopkins School of Medicine in Baltimore and co-authors.
The systematic review, which looked at 42 studies of DAAs used in interferon-free regimens, is published online in the Annals of Internal Medicine.
"There are now several highly effective and well-tolerated regimens that can be used to produce cure of hepatitis C in a wide range of chronically infected persons," Raymond Chung, MD, chief of hepatology at Massachusetts General Hospital in Boston, told MedPage Today. https://www.medpagetoday.com/reading-room/aga/lower-gi/64857?xid=nl_mpt_DHE_2017-04-28&eun=g721819d0r&pos=2
Rate Of Serious Complications Following Bariatric Surgery Varies Widely Among Accredited Centers Of Excellence, Study Suggests.
reports that the rate of serious complications following bariatric surgery varied from .6% to 10.3% among facilities that had been “accredited as centers of excellence,” according to a study published in JAMA Surgery. The study’s lead author pointed out that becoming accredited doesn’t require a “measure of outcomes, it’s just a process list.” http://khn.org/news/center-of-excellence-designation-doesnt-mean-a-lack-of-bariatric-complications/
Food Industry Seeks Delay Or Repeal Of Labeling Requirements.
citing, “petitions filed with the Food and Drug Administration,” reports that industry groups are “seeking to delay or do away with Obama-era rules governing the disclosure of calories, sugar, fiber and serving size.” Petitions have been filed by the National Association of Convenience Stores, National Grocers Association, and American Bakers Association, seeking “suspension of far-reaching Obama-era nutritional regulations.” The groups have targeted “a requirement to include calorie counts on menus,” and sought a delay on “new food labels” requiring “serving size and calorie information in a large, bold-faced font.” So far, the Post adds, “the Trump administration appears receptive.” The Chicago Tribune (4/27, Bomkamp) reports the rule to require calorie counts on menus “is in limbo, just days before it was set to take effect” on May 5. https://www.washingtonpost.com/news/wonk/wp/2017/04/27/industry-is-counting-on-trump-to-back-off-rules-that-tell-you-whats-in-your-food/?utm_term=.49a3bbec300b
Regular Exercise May Help Reduce Effects Of FTO Gene Variant That Raises Obesity Risk, Study Indicates.
reports research suggests that “when people carried” the FTO “gene variant that raises obesity risk, regular exercise seemed to reduce the effects of their DNA – by about one-third.” Investigators arrived at this conclusion after analyzing data on some “200,000 adults, mostly of European descent, who’d taken part in previous health studies,” then examining how weight and “exercise habits” went on to interact “with 2.5 million gene variants.” The findings were published online in PLOS Genetics. https://consumer.healthday.com/fitness-information-14/misc-health-news-265/no-excuses-exercise-can-overcome-the-obesity-gene-722104.html

Opioid Use Among Older Patients Increasing, Studies Suggest.
reports that, according to the CDC, Americans between the ages of 45 and 64 comprised 44 percent of deaths due to opioid overdoses in 2013 and 2014. The rising figures have spurred health officials to issue new guidelines for dosage requirements, while organizations such as the Doctors Co. are working to assist physicians in applying new CDC guidelines and patients in safely managing pain. https://www.wsj.com/articles/opiod-use-soars-among-middle-aged-and-elderly-1492999801
Climate Tied to Alcohol-Related Liver Disease Is alcoholic cirrhosis a product of cold, gray weather?
Shah noted that heavy alcohol intake can give the perception of warmth -- a fact that leads to the assumption that people in countries with colder weather drink more and might therefore have increased prevalence of alcoholic liver diseases.
And it's known that hours of sunlight are related to both temperature and depression and therefore also could influence alcohol use, he added.
Bu the assumptions have not been tested using global epidemiological data, he said. the analysis showed significant links between the AAF and average temperature, mean annual sunshine hours, and latitude, so Shah's group conducted a further multivariate analysis, adjusting for the percentage of binge drinkers among active drinkers and average alcohol consumption.
That analysis showed average temperature and sunshine hours remained independently associated with AAF. Shah said. For instance, for every degree Celsius increase in temperature there is an observed 0.3% decrease in AAF.
Although there are likely many other factors that come into play, Shah said, one possible implication of the study is that public policy measures to prevent alcohol cirrhosis should be especially active in colder climates. https://www.medpagetoday.com/MeetingCoverage/EASL/64734?xid=nl_mpt_DHE_2017-04-24&eun=g721819d0r&pos=2
Lupus Patients at Risk for Stroke Risks high for women, the young, and during the year after diagnosis
several factors could have contributed to increased stroke incidence in SLE patients, notably that inflammation, possibly stemming from immunological challenges like infections or lupus flares, might have led to atherosclerosis or thrombosis.
"Risk factors that predict stroke in the general population do not appear to accurately predict stroke in SLE," they wrote. "This suggests that an SLE-specific risk score, with evidence-based guidelines for stroke prevention, is necessary to decrease the excess risk we observe in these patients." https://www.medpagetoday.com/Rheumatology/Lupus/64729?xid=nl_mpt_DHE_2017-04-24&eun=g721819d0r&pos=0

Genetic Testing Creates New Challenge For Parents To Decide When To Share Information About Genetic Risks With Children.
reports the growth of genetic testing has “created a new challenge for parents and medical experts: when to share information with children who may inherit a genetic risk.” The article reports that some experts recommend waiting to tell minors because they may not be able to cope with the information, while others recommend sharing the information with adolescents because that may help them prepare for the possibility that they also carry the same genetic risk. https://www.nytimes.com/2017/04/20/well/family/when-to-tell-daughters-about-a-genetic-breast-cancer-risk.html?_r=0
Consumption Of Artificially-Sweetened Beverages May Be Linked To Higher Risk Of Stroke, Dementia, Study Suggests.
reports that the study, published in Stroke, found that individuals “who drank at least one artificially-sweetened beverage a day had almost three times the risk of developing stroke or dementia.” The researchers “did not find the same link between stroke and dementia in people who drank sugar-sweetened beverages, but the authors say that doesn’t mean it’s time for people to start” consuming “those either.” The researchers controlled for several other risk factors, including age, sex, caloric intake, education, diabetes, and the presence of genetic risk factors for Alzheimer’s.
The results showed that people who consumed at least one artificially-sweetened drink a day were three times as likely to develop ischemic stroke and 2.9 times as likely to develop Alzheimer’s disease dementia.
MAYBE they impact cravings, gut microbes, and hormones leading to more systemic inflammation that impacts the brain???
In addition to being an observational study which cannot prove cause and effect, the authors note the study several other limitations, including that the overwhelming majority of participants were white. People did not drink sugary drinks as often as diet ones, which the authors said could be one reason they did not see the same link with regular soda. http://www.cbsnews.com/news/diet-soda-dementia-stroke-heart-risks-new-study/
CDC Names Top Culprits in Foodborne Illness 2016 data now include culture-independent diagnostic testing results
Campylobacter and Salmonella were responsible for the highest number of reported bacterial foodborne-illnesses in 2016, CDC researchers said.
Overall, both pathogens each caused over 8,000 infections, confirmed either via traditional method or only by culture-independent diagnostic tests. Shigella was a distant third, involved in 2,913 bacterial foodborne-illnesses in 2016, according to Ellyn Marder, MPH, and colleagues.
But compared with 2013-2015, incidence of Campylobacter was significantly lower (11% decrease) when including only confirmed infections, but not significantly different when including both confirmed and those confirmed using only culture-independent diagnostic tests (CIDTs), the authors reported in Morbidity and Mortality Weekly Report.

Consumption Of Low-Calories Sweeteners Associated With Upregulation Of Gene Expression For Glucose Transporters,
http://www.mdedge.com/clinicalendocrinologynews/article/135906/obesity/low-calorie-sweeteners-may-allow-more-glucose-enter
Individuals in both groups had kept a 7-day food diary before the biopsies were taken, so Dr. Sen and his coinvestigators knew whether or not they had consumed low-calorie sweeteners and in what quantity. Reported sweeteners were sucralose, acesulfame-potassium, and aspartame.
The adipose tissue biopsies were examined for mRNA expression of adipogenic genes, as well as for glucose transporters and inflammatory markers.
In individuals with low-calorie sweetener exposure, the glucose transporter GLUT1 was overexpressed by 2- to 2.2-fold, while the glucose transporter GLUT4 was overexpressed by a factor of 2.7-4.3.
In addition, low-calorie sweetener consumption was associated with up to 2.5-fold overexpression of the sweet taste receptor TAS1R3. Sweet taste receptors are G protein–coupled receptors that are present in taste buds and in other tissues, serving as carbohydrate sensors.
Adipogenic genes were also overexpressed; a 1.5- to 2.4-fold increase was seen in PPARG, for example.
Medicinal Cannabis Treatments Coming, Experts Say
Medicinal cannabis industry officials and scholars here touted potential breakthroughs to treat health problems and questioned why cannabidiol (CBD) is not mandatory for athletes to address traumatic brain injury (TBI). Others, meanwhile, cautioned the field needs much more research and regulation.

Medical professionals including Titus, a former physiotherapist working with athletes, cited cannabis medicines being developed (including these by Axim Biotech) for heath problems including:
Chronic pain
Cancer-induced pain and nausea
Irritable bowel syndrome and irritable bowel disease
Psoriasis and dermatitis

Endocrine-Disrupting Chemicals May Be Responsible For Decline In Sperm Counts, Experts Say.
reports growing concern about a potential “reproductive crisis” that could arise if sperm counts continue to decline as they have been in many countries for decades. The article highlights experts who say that endocrine-disrupting chemicals (EDCs) are responsible for the decline in sperm counts as well as other negative health outcomes based on studies conducted with animals. The article reports that the National Institutes of Health says that EDCs “may...produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife,” and that further study is needed. The article adds the National Institute of Environmental Health Sciences says EDCs “may pose the greatest risk during prenatal and early postnatal development when organ and neural systems are forming.” Endocrine Society member Andrea Gore, a professor of pharmacology at the University of Texas at Austin and editor of the journal Endocrinology, said, “Not everyone who wants to reproduce will be able to.

Video Chats Helping People Fight Diabetes.
reports on Virta Health, “one of a new crop of high-tech companies that have designed programs aimed at helping people prevent or even reverse their diabetes” through diet and drug recommendations. Daily, “patients use an app to upload their blood sugar levels, blood pressure, body weight and other measurements” that are monitored by a registered dietitian who checks in by phone or email. Initial results that examined the program’s impact on 241 Type 2 diabetics, published in the journal JMIR Diabetes in March, “found that 56 percent had lowered their blood sugar to nondiabetic levels after 10 weeks,” while about 90 percent had reduced or stopped their use of insulin altogether.

WHY???
Artificial Sweetener Sucralose May Activate Genes Associated With Fat Production, Inflammation, Research Suggests.
The researchers saw evidence of increased transport of glucose into cells—meaning accumulation of more sugar in the blood— and overexpression of fat-producing genes, compared to samples from subjects who didn’t use the sweeteners.
Part of the reason may be that low-calorie sweeteners appear to increase “sweet taste receptors” in abdominal fat, and that allows glucose to enter the cells more readily, the researchers believe. Basically, these receptors are looking for a sweet fix, and low-cal sweeteners—which are often several-fold sweeter than sugar—satisfy that need. Researchers noted that those who regularly consume artificial sweeteners had 2.5-fold higher sweet taste receptor overexpression than those who don’t eat the stuff.
As more glucose enters the cells as a result of these receptors, the body absorbs it into the bloodstream, raising blood sugar levels in the body. This process often leads to abdominal fat storage, too. Over time, that can mess with your metabolism, leading to greater fat production. http://www.menshealth.com/weight-loss/artificial-sweetener-and-weight-gain

Multiple Metabolic Abnormalities Seen in Lupus Targeting insulin resistance alone won't be enough
When compared with a control group, patients with systemic lupus erythematosus (SLE) had higher insulin resistance and hyperglucagonemia, even when their fasting glucose, glucose response, and skeletal muscle GLUT4 translocation appeared normal, reported Fabiana Benatti, PhD, of the University of Sao Paulo School of Medicine, and colleagues.
Specifically, SLE patients who underwent meal tolerance tests (MTT) showed higher:
Fasting insulin levels: effect size 1.2 (P=0.01)
Homeostatic model assessment of insulin resistance (HOMA IR): effect size 1.1 (P=0.03)
Insulin-to-glucose ratio response to MTT: effect size 1.2 (P=0.02)
Fasting glucagon levels: effect size 2.7 (P=0.002)
Glucagon response to MTT: effect size 2.6 (P=0.0001)
The authors noted that one of the most striking findings of the study was that the higher insulin levels in SLE patients were not able to control glucagon production. Although glucose and insulin effectively suppressed glucagon secretion during MTT, the SLE group's glucagon levels remained higher than the control group's levels at all times.
The investigators also noted that insulin sensitivity was correlated with inflammation markers C-reactive protein and leptin, which could point to inflammation having a role in insulin resistance in SLE.
They added that drugs -- notably, prednisone and hydroxychloroquine -- could have influenced their results.
"Corticosteroids have been shown to decrease glucose tolerance by increasing hepatic glucose production and decreasing peripheral glucose uptake via a decrease in skeletal muscle and adipose tissue insulin sensitivity," they stated. "Because 30% of our SLE patients were using prednisone, this could have contributed to the higher insulin resistance observed in this group." In contrast, hydroxychloroquine in SLE patients has been linked to lower levels of fasting glucose and HOMA IR, and reduced risk of type 2 diabetes. The researchers did not observe any association between hydroxychloroquine use and insulin sensitivity. "However, because 70% of our patients were using this medication, it is possible that hydroxychloroquine may have attenuated potential deleterious effects of prednisone on insulin sensitivity," they wrote. https://www.medpagetoday.com/Rheumatology/Lupus/64321?xid=nl_mpt_DHE_2017-04-05&eun=g721819d0r&pos=1

Investigators “revealed that mice who were subjected to binge drinking habits similar to those practiced by humans gave birth to offspring with high blood sugar and other changes in glucose function.” The findings were presented at ENDO 2017. http://www.medicaldaily.com/history-drinking-alcohol-pregnancy-past-binging-may-harm-future-children-study-414812
Study Refutes Notion That Being Moderately Overweight Decreases Risk Of Dying.
the Annals of Internal Medicine is skeptical of the “popular idea, supported by some studies, that people who are overweight but not obese live longer than thinner peers.” The new study found that “the fatter we get, the more likely we are to die young from any cause and particularly from heart disease, cancer or respiratory disease.” reports lead researcher Andrew Stokes at Boston University School of Public Health and his group “found a 6 percent increased risk of dying from any cause among individuals with a history of being overweight.” Stokes said that 6 percent “is only a modest increase,” but it’s still “extremely worrisome” because so many American are overweight. The study “focused on each person’s maximum BMI over a 16-year period,” which Stokes “says makes the findings more reliable than earlier studies that have used a single BMI without regard to whether someone is gaining or losing weight at the time of the measurement.” We found that after considering weight history, the apparent paradoxical association between overweight/obesity and the risk of dying completely disappeared.” However, Stokes added the study is not able to prove that gaining additional weight increases the risk of death, nor can it conclude losing the weight would reduce the extra risk http://www.npr.org/sections/health-shots/2017/04/03/522475728/carrying-some-extra-pounds-may-not-be-good-after-all

UN Doc: Climate Change is New Challenge in Fighting Disease Outbreaks
British trained doctor David Nabarro, who is in the race to be the next head of the World Health Organization (WHO), said infectious diseases, like cholera and Ebola, wreak havoc if they are not identified and managed quickly.
"You can't do this stuff with white coats and kind of control from outside," Nabarro told the Thomson Reuters Foundation in an interview in Bogota.
"The first thing with all this business of dealing with outbreaks is to make sure there is capacity in countries to deal with problems early," he said, adding simulation exercises are crucial in ensuring local communities are better prepared. https://www.medpagetoday.com/PublicHealthPolicy/PublicHealth/64279?xid=nl_mpt_DHE_2017-04-03&eun=g721819d0r&pos=0
