Physiological Redundancy and the Integrative Responses to Exercise

By |2020-12-17T19:36:33+00:00December 17th, 2020|

Abstract The biological responses to acute and chronic exercise are marked by a high level of physiological redundancy that operates at various levels of integration, including the molecular, cellular, organ-system, and whole-body scale. During acute exercise, this redundancy protects whole-body homeostasis in the face of 10-fold or more increases in whole-body metabolic rate. In some [...]

Design Prospective cohort study with repeated measures of diet and lifestyle factors. Setting Health Professionals Follow-Up Study cohort, United States, 1986-2016. [...]

What to do about pelvic organ prolapse

By |2020-12-17T19:36:25+00:00December 17th, 2020|

One of the most uncomfortable—and awkward—conditions that afflicts women is pelvic organ prolapse. Normally, the pelvic organs—the bladder, uterus, vagina, and rectum—are supported and held in place by a group of muscles and tissues called the pelvic floor. When these muscles weaken over time, the pelvic organs can droop down and bulge out of the [...]

Try these stretches before you get out of bed

It’s hard to jump out of bed for a great day when your muscles are stiff and your joints creaky. But you can change that by warming up and stretching before your feet ever touch the floor. “Stretching before getting out of bed can help wake up the body and improve the circulation. It can also [...]

Air pollution spikes linked to lower test results

By |2020-12-15T19:13:55+00:00December 15th, 2020|

Exposure to air pollution is linked to lower Maths and English test results amongst primary school children, according to a study led by researchers at the University of Utah.The researchers analysed the Maths and English test results of pupils at 156 primary schools in Salt Lake County in 2017. They then compared this to each [...]

“Super-Spreaders” and Person-to-Person Transmission of Andes Virus in Argentina

By |2020-12-15T19:13:54+00:00December 15th, 2020|

Abstract BACKGROUND From November 2018 through February 2019, person-to-person transmission of Andes virus (ANDV) hantavirus pulmonary syndrome occurred in Chubut Province, Argentina, and resulted in 34 confirmed infections and 11 deaths. Understanding the genomic, epidemiologic, and clinical characteristics of person-to-person transmission of ANDV is crucial to designing effective interventions.     Credit: CDC Read more… The post [...]

CDC advisory panel’s lone dissenter on why long-term care residents shouldn’t receive Covid-19 vaccine first

By |2020-12-15T19:13:54+00:00December 15th, 2020|

When a Centers for Disease Control and Prevention advisory committee voted Tuesday to recommend residents of long-term care facilities should be at the front of the line — with health care providers — for Covid-19 vaccines, the lone dissenting voice came from a researcher who studies vaccines in older adults. Helen Keipp Talbot — who is known [...]

Situation Summary Between epidemiological week (EW) 1 and EW 471 of 2020, 2,163,354 dengue cases were reported in the Region of the Americas (incidence rate of 221.6 cases per 100,000 population), including 872 deaths. Of these cases, 963,787 (45%) were confirmed by laboratory criteria and 5,197 (0.2%) were classified as severe dengue. The case fatality [...]

Diabetes drug linked to lower COVID-19 death rate in women

By |2020-12-15T19:13:51+00:00December 15th, 2020|

A Lancet Healthy Longevity study yesterday found that metformin—a common, generic type 2 diabetes medication used to manage blood sugar levels—is associated with significantly lower COVID-19 death risk in women, but not in men. Severe COVID-19 outcomes for people with diabetes have been widely observed, including greater risk of intensive care unit admission, intubation for mechanical ventilation, and [...]

Extremely drug-resistant NDM-9-producing ST147 Klebsiella pneumoniae causing infections in Italy, May 2020 separator

By |2020-12-15T19:13:50+00:00December 15th, 2020|

A large outbreak sustained by New Delhi metallo-beta-lactamase (NDM)-1-producing Klebsiella pneumoniae sequence type (ST) 147 occurred in Tuscany, Italy in 2018–2019 [1,2]. In 2020, NDM-9-producing K. pneumoniae were isolated in the same geographical area. In this study, comparisons at genomic level of these recent isolates with strains representative of the 2018–2019 outbreak were carried out. The 2020 strains were [...]
