Graves Disease Explained.
reports that the autoimmune thyroid disorder known as “Graves’ disease affects approximately one in 200 people, according to the National Institutes of Health, and it occurs much more often in women than men.” Endocrine Society Past President Leonard Wartofsky, MD, an endocrinologist, explained, “There are effects on virtually every tissue in the body, every organ, every system. .. The thyroid is important for heart, kidney, and muscle function, but in the case of hyperthyroidism it’s excessive.” The article goes on to explain theories of what causes the disease, its symptoms, how it is diagnosed, and how it is treated. http://www.goodhousekeeping.com/health/news/a47975/what-is-graves-disease/?src=socialflowTW

Testosterone Injections May Be Linked To Increased Risk For Cardiovascular Events In Older Men,
So if you read my other post about testosterone reducing frailty, then see this article, it makes you opt out of treatment.
reports that research indicated “men aged at least 65 years receiving testosterone injections had an increased risk for cardiovascular events, including myocardial infarction, stroke or unstable angina, within 7 days of administration.” However, “the risk was not increased in younger men.” The findings were published in Clinical Endocrinology. https://www.healio.com/endocrinology/hormone-therapy/news/in-the-journals/%7B25f37120-9443-4977-b4ab-824498ba3de9%7D/testosterone-injection-in-older-men-increases-cv-risk
Asthma In Women May Be Linked To Changes In Levels Of Female Hormones,
reports that research suggests “there may be a link between asthma in women and changes in levels of female hormones such as estrogen and progesterone.” Investigators “reviewed more than 50 studies of more than 500,000 women with asthma from puberty to age 75.” The researchers “found that starting to have periods before age 11 and having irregular periods were associated with a higher risk of asthma.” The findings were published in the Journal of Allergy and Clinical Immunology. https://consumer.healthday.com/respiratory-and-allergy-information-2/asthma-news-47/female-hormones-may-play-part-in-asthma-731207.html
Research Offers More Evidence Of Association Between Lower Free Testosterone Levels And Higher Levels Of Frailty In Older Men.
reports that research “provides more evidence of a link between lower free testosterone levels and higher levels of frailty in older men.” However, “a researcher says proof of a causal connection remains elusive.” In an interview, lead author Agnieszka Swiecicka, MD, said, “Our study demonstrates clear associations between testosterone and frailty progression, and, although causality and directionality of the hormone/frailty relationships require clarification, the results presented here make a strong case for large interventional trials of testosterone therapy in frail men to determine whether such treatment would be beneficial.” The findings were published in the Journal of Clinical Endocrinology and Metabolism. https://www.mdedge.com/clinicalendocrinologynews/article/159488/mens-health/free-testosterone-linked-frailty-older-men

More Women Aged 40 And Older Having Children,
reports new data suggest the birthrate in the US reached a new low in 2017; however, “among women over 40, the birthrate has increased” with women aged 40 to 44 having a four percent increase in birthrate and women aged 45 to 49 having a .1 percent increase. According to Dr. Norbert Gleicher of the Center for Human Reproduction, “This would have been unimaginable 10 years ago.” http://abcnews.go.com/GMA/Wellness/women-babies-50/story?id=52971244
Presence Of Microbiota In The Infant Gut Appears To Mediate The Link Between Maternal And Child Overweight Status, Particularly In Cesarean-Delivered Babies
“Babies born to overweight or obese mothers, either vaginally or via cesarean section, are more likely to become overweight or obese than those born vaginally to normal-weight mothers,” researchers found. And, “in addition to mode of birth, the presence of microbiota in the infant gut appears to mediate the link between maternal and child overweight status, particularly in cesarean-delivered babies,” the study revealed. The findings were published online in JAMA Pediatrics. The authors of an accompanying editorial observed, “The current study adds important information supporting the interdependency of maternal weight status and mode of delivery in forming the ‘microbial communities of early life,’ which are linked to offspring weight status.” https://jamanetwork.com/journals/jamapediatrics/article-abstract/2672735

ACIP Reinstates FluMist for 2018-2019 Flu Season Committee persuaded by new efficacy analyses
After a 2-year absence, FluMist is back on the 2018-2019 influenza vaccine schedule, following a vote from the CDC Advisory Committee on Immunization Practices (ACIP) here. The panel also gave a unanimous endorsement to the Heplisav-B vaccine against hepatitis B virus.
ACIP members voted 12-2 to include the live attenuated influenza vaccine (LAIV) as "an option for influenza vaccination for persons for whom it is appropriate" in the 2018-2019 influenza season. An additional motion to give a preferential recommendation to the inactivated influenza vaccine (IIV) and recombinant influenza vaccine (RIV) over LAIV was voted down 3-11.
The vaccine was also added back to the Vaccines for Children (VFC) program in a 14-0 vote.
What changed their minds? CDC research from prior studies of live attenuated influenza vaccine showed that effectiveness of LAIV was 45% against influenza A and B, with 25% protection against influenza A (H1N1)pdm09 compared with unvaccinated children. CDC researchers also found that while inactivated influenza vaccine was "better" in all age groups against influenza A(H1N1)pdm09, compared with LAIV, there was no statistically significant difference in protection between the two vaccines for influenza A (H3N2) and influenza B viruses. https://www.medpagetoday.com/meetingcoverage/acip/71298?xid=nl_mpt_DHE_2018-02-22&eun=g721819d0r&pos=0&utm_source=Sailthru&utm_medium=email&utm_campaign=Daily%20Headlines%202018-02-22&utm_term=Daily%20Headlines%20-%20Active%20User%20-%20180%20days

Flu Vax Data 'Only Tell Half the Story'
Flu vaccine efficacy numbers may seem lower than normal, but any flu vaccine is better than no vaccine, says William Schaffner, MD, professor of preventive medicine and infectious diseases at Vanderbilt University, in this MedPage Today video.
Schaffner characterizes the current vaccine's efficacy numbers as "not bad," and reiterates that vaccination helps prevent severe flu even if it isn't perfect. He also emphasizes the importance of pediatric immunizations, given the latest CDC data about pediatric deaths, and looks ahead to upcoming flu vaccine research.
Following is a transcript of his remarks: https://www.medpagetoday.com/infectiousdisease/uritheflu/71237?xid=nl_mpt_DHE_2018-02-20&eun=g721819d0r&pos=1&utm_source=Sailthru&utm_medium=email&utm_campaign=Daily%20Headlines%202018-02-20&utm_term=Daily%20Headlines%20-%20Active%20User%20-%20180%20days

Numerous Factors Contributing To Precipitous Decline In America’s Fertility, Economist Explains.
“The Upshot,” economist Lyman Stone at Demographic Intelligence writes, “America’s fertility is in precipitous decline,” as projected by a “team of forecasters at Demographic Intelligence.” The forecasters projected “3.84 million births in 2017, down from about 3.95 million in 2016.” Stone breaks down the data in detail, concluding that “with marriage coming later, the share of women at peak childbearing ages (20 to 40) who are married has steadily fallen.” At the same time, “unmarried births are falling, too.” Americans appear to be “having less sex than they used to,” and people in the US “are improving their ability to avoid unwanted pregnancies far faster than they are improving the ability to achieve desired pregnancy.” https://www.nytimes.com/2018/02/13/upshot/american-fertility-is-falling-short-of-what-women-want.html

Gene Assay Informs Chemo Decision in Breast Cancer 10-year recurrence risk of 3.5% in low-risk, node-positive disease
This study identified a substantial population of patients with one to three positive lymph nodes with sufficiently low risk to safely avoid chemotherapy. By tailoring risk categorization to the number of positive nodes, 37% of patients with a single positive lymph node and 15% of patients with two positive nodes were characterized as low risk, by Prosigna, with very favorable outcomes when treated with adjuvant endocrine therapy alone.
"Although chemotherapy could still provide some relative additional benefit for patients, when the low-risk group carries a residual rate of recurrence of <5% at 10 years, the absolute benefit that can be achieved by still giving chemotherapy could be, at best, very small (and more than counterbalanced by toxicities)."

Fat Lost On Crash Diets May Have Negative Impact On Heart Health
reports that a study “suggests that fat lost on crash diets may clog the heart and reduce its function.” However, “this effect appears temporary.” Rayner's team theorized that the sudden drop in calories causes fat to be released from different parts of the body into the blood. It's then taken up by the heart muscle.
But the negative changes didn't last. By eight weeks, heart function and heart fat were better than normal. Body fat, cholesterol and all of the other metabolic measures also continued to improve. The findings were presented at the European Society of Cardiology meeting. https://consumer.healthday.com/vitamins-and-nutrition-information-27/dieting-to-lose-weight-health-news-195/crash-diets-might-derail-your-heart-health-730863.html
Lung Disease Common in Late-Onset SLE Rates of interstitial lung disease more than doubled
Many potential factors may contribute to the increased pulmonary risks among late-onset lupus patients, including effects on both the innate and adaptive immune systems. For example, neutrophils in older individuals are less capable of killing phagocytosed pathogens but have increased apoptosis, and thymic production of naive T-cells declines, leading to proliferation of memory T cells and a resulting proinflammatory state.
An additional contributory factor for interstitial lung disease in older patients may be a possible SLE-Sjogren's syndrome overlap syndrome, which has been reported by several groups. The prevalence of interstitial lung disease in Sjogren's syndrome, at 9% to 75%, is much higher than in SLE, at 1% to 15%, so an overlap syndrome could explain the high incidence in older patients.
"In addition to a possible Sjogren's overlap phenotype in late-onset SLE, factors such as duration of disease, environmental exposures, and smoking trends over time might also correlate with SLE interstitial lung disease," the researchers observed. https://www.medpagetoday.com/rheumatology/lupus/70981?xid=nl_mpt_DHE_2018-02-07&eun=g721819d0r&pos=0&utm_source=Sailthru&utm_medium=email&utm_campaign=Daily%20Headlines%202018-02-07&utm_term=Daily%20Headlines%20-%20Active%20User%20-%20180%20days

ACIP Issues Updated Adult Vax Schedule Changes to shingles, MMR vaccine recommendations
Changes to the adult immunization schedule include a preferential recommendation for a new recombinant zoster vaccine for older adults, and a third dose of measles mumps rubella (MMR) vaccine to adults who may be at risk of mumps during an outbreak.
The CDC Advisory Committee for Immunization Practices (ACIP) recommended changes on use of herpes zoster vaccine and use of an additional MMR dose, with additional changes in the wording of tetanus, diphtheria, and pertussis (Tdap), and other vaccine recommendations, wrote David K. Kim, MD, on behalf of the ACIP, and colleagues, in the Annals of Internal Medicine.
The authors noted that the ACIP updated the standards of adult immunization practice "to promote the integration of vaccinations as a part of routine clinical care for adults." This means healthcare providers should assess a patient's vaccination status at every clinical encounter, "strongly recommend" needed vaccines to patients, offer vaccines recommended to patients, and document vaccines administered in the state or local immunization information system. https://www.medpagetoday.com/primarycare/vaccines/70970?xid=nl_mpt_DHE_2018-02-06&eun=g721819d0r&pos=3&utm_source=Sailthru&utm_medium=email&utm_campaign=Daily%20Headlines%202018-02-06&utm_term=Daily%20Headlines%20-%20Active%20User%20-%20180%20days

contributor David DiSalvo writes that research published in the International Journal of Nanomedicine suggests vitamin D3 supplements may be beneficial for individuals “at risk for or already have heart disease.”
Cardiovascular Business (1/31, Slachta) reports that investigators “found vitamin D3 to be a powerful stimulator of nitric oxide, which is key in regulating blood flow and preventing the formation of clots.” Additionally, “the vitamin...appeared to significantly reduce the level of oxidative stress in the cardiovascular system.” http://www.cardiovascularbusiness.com/topics/acute-coronary-syndrome/high-doses-vitamin-d-shown-restore-cardiovascular-system-post-heart-attack
Average American Could Lose Nearly Six Pounds Of Fat Per Year By Standing Six Hours Each Day
reports a new study published in the European Journal of Preventive Cardiology suggests that if Americans, who sit an average of more than seven hours each day, were to stand for six of those hours, the average person “would burn an additional 54 calories a day.” This, researchers found, “could translate into a loss of about 5.5 pounds of body fat per year” for the average American, excluding diet changes and extraneous exercise. http://www.latimes.com/science/sciencenow/la-sci-sn-standing-burns-calories-20180131-story.html
