Glucosamine may reduce overall death rates as effectively as regular exercise, study suggests — ScienceDaily

Glucosamine supplements may reduce overall mortality about as well as regular exercise does, according to a new epidemiological study from West Virginia University.

“Does this mean that if you get off work at five o’clock one day, you should just skip the gym, take a glucosamine pill and go home instead?” said Dana King, professor and chair of the Department of Family Medicine, who led the study. “That’s not what we suggest. Keep exercising, but the thought that taking a pill would also be beneficial is intriguing.”

He and his research partner, Jun Xiang — a WVU health data analyst — assessed data from 16,686 adults who completed the National Health and Nutrition Examination Survey from 1999 to 2010. All of the participants were at least 40 years old. King and Xiang merged these data with 2015 mortality figures.

After controlling for various factors — such as participants’ age, sex,

More than one in three respondents reported clinically significant levels of depression, exceeding rates seen before 2020 — ScienceDaily

Though childbirth is often anticipated with optimism and enthusiasm, approximately 10 to 20 percent of pregnant individuals also experience mental health challenges during the weeks immediately before and after birth. Depression, anxiety and trauma-related disorders can all be exacerbated by increased stress related to pregnancy and postpartum experiences. But it’s unknown how the stressors of a significant health pandemic can impact these complications. In a new study published in Psychiatry Review, researchers from Brigham and Women’s Hospital surveyed pregnant women and those who had recently given birth, finding concerning rates of depression, generalized anxiety and post-traumatic stress disorder (PTSD) symptoms, which were found to be exacerbated by COVID-19-related grief and health worries.

“We know the perinatal period is already a time in which women are particularly vulnerable to mental health concerns,” said corresponding author Cindy Liu, PhD, of the Department of Pediatric Newborn Medicine and the Department of Psychiatry.

A Quick Look At Technology’s Expected EPS Growth Rates In 2021

In the weekly “This Week in Earnings” Refinitiv publishes expected, full-year, growth rates for next year on a weekly basis.

As of the end of November, IBES data by Refinitiv is expecting the Tech sector to grow EPS 15% next year, and as the above graph shows, a slow but expected decline has been occurring in the Tech sector’s expected EPS growth over the last 6 months. (That decline is not unusual.)

Here is another way of looking at similar sector by quarter:

Looking at the left-hand columns from Refinitiv, the expected tech sector EPS growth in January ’20 (not shown) was roughly 10%, so the sector has recovered nearly 60% of what was expected at the start of the year. For 2021, the initial estimates were looking for 17% expected growth so – as of today – the expected 14% growth for next year has almost closed the Covid-19

Time to rethink predicting pandemic infection rates? — ScienceDaily

During the first months of the COVID-19 pandemic, Joseph Lee McCauley, a physics professor at the University of Houston, was watching the daily data for six countries and wondered if infections were really growing exponentially. By extracting the doubling times from the data, he became convinced they were.

Doubling times and exponential growth go hand in hand, so it became clear to him that modeling based on past infections is impossible, because the rate changes unforeseeably from day to day due to social distancing and lockdown efforts. And the rate changes differ for each country based on the extent of their social distancing.

In AIP Advances, from AIP Publishing, McCauley explains how he combined math in the form of Tchebychev’s inequality with a statistical ensemble to understand how macroscopic exponential growth with different daily rates arise from person-to-person disease infection.

“Discretized ordinary chemical kinetic equations applied to infected, uninfected,

COVID-19 patients survive in-hospital cardiac arrest at pre-pandemic rates — ScienceDaily

It isn’t a death sentence if a COVID-19 patient suffers a cardiac arrest while getting treatment for the virus in the hospital, according to new research that contradicts reports from early on in the pandemic. The new insight from a researcher in the Perelman School of Medicine at the University of Pennsylvania still shows that such events remain deadly, but can be survived at a rate likely near what it was among other hospital inpatients before the pandemic broke out. This analysis was presented during the American Heart Association’s annual scientific meeting this month.

“Early studies showed extremely low rates of COVID-19 patients who were resuscitated successfully and went on to survive after suffering from cardiac arrest. The first study from Wuhan demonstrated just a 2.9 percent 30-day survival rate and a second small cohort from New York City showed absolutely no survival,” said Oscar Mitchell, MD, a fellow in

Children and adolescents more likely to experience higher rates of depression and anxiety during and after enforced isolation ends — ScienceDaily

The COVID-19 pandemic has necessitated widespread social isolation, affecting all ages of global society. A new rapid review in the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP), published by Elsevier, reports on the available evidence about children and young people specifically, stating that loneliness is associated with mental health problems, including depression and anxiety-potentially affecting them years later.

The review, which synthesizes over 60 pre-existing, peer-reviewed studies on topics spanning isolation, loneliness and mental health for young people aged between 4 and 21 years of age, found extensive evidence of an association between loneliness and an increased risk of mental health problems for children and young people.

“As school closures continue, indoor play facilities remain closed and at best, young people can meet outdoors in small groups only, chances are that many are lonely (and continue to be so over time),” said lead author, Maria Loades,

Apple slices commission rates in half with launch of new app developer program

Apple has announced a commission-cutting app developer program for small businesses. 

Apple announced the new scheme on Wednesday. The Cupertino, Calif.-based company generally charges up to 30% for in-app purchases made through apps hosted on the iOS App Store, and this ‘tax’ applies to both digital goods and services. 

Perhaps launched in mind of brewing legal battles surrounding the existing commission rate, Apple’s new offering, the “App Store Small Business Program,” will slice commission in half from 30% to 15%. 

“Existing developers who made up to $1 million in 2020 for all of their apps, as well as developers new to the App Store, can qualify for the program and the reduced commission,” Apple says. “If a participating developer surpasses the $1 million threshold, the standard commission rate will apply for the remainder of the year.”

Suicide rates increase during hurricanes, tornadoes and other similar events — ScienceDaily

Disasters like hurricanes and tornadoes are occurring with increasing frequency and severity across the globe. In addition to impacting local communities, infrastructure and the economy, these disasters also can lead to severe emotional distress and anxiety for those living in their paths.

A team of researchers including the University of Delaware’s Jennifer Horney, founding director of the epidemiology program in the College of Health Sciences, examined the impact of 281 natural disasters on suicide rates during a 12-year span.

Horney and others looked at disaster declaration data and found overall suicide rates increased by 23% when compared to rates before and after the disaster. Suicide rates increased for all types of disasters — including severe storms, floods, hurricanes and ice storms — with the largest overall increase occurring two years after a disaster, according to an article published in The Journal of Crisis Intervention and Suicide Prevention.

“That finding

COVID-19 infection rates low in people with rheumatic diseases, most report mild illness — ScienceDaily

A new study shows that the COVID-19 infection incidence has been low in people with rheumatic diseases, and most of those infected experience a mild course of illness. Additionally, fatalities have been low among rheumatic disease patients infected with COVID-19. Details of this research was presented at ACR Convergence, the American College of Rheumatology’s annual meeting.

COVID-19 is the infectious disease caused by the novel coronavirus SARS-CoV-2. As the COVID-19 pandemic surged worldwide in early 2020, the risk of serious infection, complications or fatality was unknown for people with rheumatic disease. Many patients with rheumatic disease are treated with immunosuppressant medications that leave them more susceptible to infection.

As the pandemic began, it was unclear how people with rheumatic diseases, on immunosuppressant therapy, were affected by a COVID-19 infection. Some early studies even suggested that these drugs could have a protective effect, but concerns remained about the vulnerability of this

Focus on COVID-19 deaths in under-65s for better insights into infection rates — ScienceDaily

Simply comparing the total number of deaths across countries may provide a misleading representation of the underlying level of transmission of SARS-CoV-2, the virus that causes COVID-19, because of large differences in reported COVID-19 death rates in elderly populations in different countries.

The research, conducted by scientists at the University of Cambridge and the Institut Pasteur, was published today in the leading journal Nature. It highlights how large COVID-19 outbreaks in European nursing homes, and the potential for missing deaths in some Asian and South American countries, have skewed COVID-19 death data for older age groups, rendering cross-country comparisons of the scale of the pandemic inaccurate.

The researchers say that reporting of deaths from COVID-19 among those under the age of 65 is likely to be far more reliable, and can therefore give clearer insights into the underlying transmission of the virus and enable better comparisons between countries —
