Factors associated with #sleep disturbance in patients with chronic #obstructive pulmonary disease

Poor sleep quality in patients with chronic obstructive pulmonary disease (#COPD ) has been associated with poor health outcomes. However, there is a lack of research on factors associated with sleep disturbance in patients with COPD.. This was a prospective, multicenter cross‐sectional study enrolling a sample of 245 COPD subjects. All patients completed the patient‐reported measure, the COPD and Asthma Sleep Impact Scale (CASIS) to … Continue reading Factors associated with #sleep disturbance in patients with chronic #obstructive pulmonary disease

Google searches for #suicide and suicide risk factors in the early stages of the #COVID-19 pandemic

A novel coronavirus (SARS-CoV-2), which causes the COVID-19 respiratory illness, emerged in December of 2019 and has since spread globally. The dramatic lifestyle changes and stressors associated with this pandemic pose a threat to mental health and have the potential to exacerbate risk factors for suicide. We used autoregressive integrated moving average (ARIMA) models to assess Google Trends data representing searches in the United States … Continue reading Google searches for #suicide and suicide risk factors in the early stages of the #COVID-19 pandemic

#Hyperglycaemia is associated with impaired muscle signalling and #aerobic adaptation to exercise

Increased aerobic exercise capacity, as a result of exercise training, has important health benefits. However, some individuals are resistant to improvements in exercise capacity, probably due to undetermined genetic and environmental factors. Here, we show that exercise-induced improvements in aerobic capacity are blunted and aerobic remodelling of skeletal muscle is impaired in several animal models associated with chronic hyperglycaemia. Our data point to chronic hyperglycaemia … Continue reading #Hyperglycaemia is associated with impaired muscle signalling and #aerobic adaptation to exercise

Sex-specific associations between #erythrocyte measures and obstructive #sleep apnea

STUDY OBJECTIVES:Hypoxemic effects of obstructive sleep apnea (OSA) have been implicated in changes in erythropoiesis and hence erythrocyte measures. Sex differences are evident in both OSA and erythropoiesis. Whether sex modulates the relationship between severity of OSA and erythrocyte measures has not previously been studied.. ..RESULTS:In multiple regression models, we found significant interactions between sex and oxygen desaturation index and apnea-hypopnea index on erythrocyte measures. … Continue reading Sex-specific associations between #erythrocyte measures and obstructive #sleep apnea

The human #cerebellum has almost 80% of the surface area of the #neocortex

The surface of the human cerebellar cortex is much more tightly folded than the cerebral cortex. It was computationally reconstructed for the first time to the level of all individual folia from multicontrast high-resolution postmortem MRI scans. Its total shrinkage-corrected surface area (1,590 cm2) was larger than expected or previously reported, equal to 78% of the total surface area of the human neocortex. The unfolded … Continue reading The human #cerebellum has almost 80% of the surface area of the #neocortex

Conservation of #brain connectivity and wiring across the mammalian class

Over 100 years ago, Ramon y Cajal hypothesized that two forces played a role in the evolution of mammalian brain connectivity: minimizing wiring costs and maximizing conductivity speed. Using diffusion MRI, we reconstructed the brain connectomes of 123 mammalian species. Network analysis revealed that both connectivity and the wiring cost are conserved across mammals. We describe a conservation principle that maintains the overall connectivity: species … Continue reading Conservation of #brain connectivity and wiring across the mammalian class

Complementary contributions of non-REM and #REM sleep to visual #learning

Sleep is beneficial for learning. However, it remains unclear whether learning is facilitated by non-rapid eye movement (NREM) sleep or by REM sleep, whether it results from plasticity increases or stabilization, and whether facilitation results from learning-specific processing. Here, we trained volunteers on a visual task and measured the excitatory and inhibitory (E/I) balance in early visual areas during subsequent sleep as an index of … Continue reading Complementary contributions of non-REM and #REM sleep to visual #learning

Nine-year prospective efficacy and safety of brain-responsive #neurostimulation for focal #epilepsy

Prospectively evaluate safety and efficacy of brain-responsive neurostimulation in adults with medically intractable focal onset seizures (FOS) over 9 years.. Adults treated with brain-responsive neurostimulation within 2 year feasibility or randomized controlled trials enrolled into a long-term prospective open label trial (LTT) to assess safety, efficacy, and quality of life (QOL) over an additional 7 years. Safety was assessed as adverse events (AEs), efficacy as … Continue reading Nine-year prospective efficacy and safety of brain-responsive #neurostimulation for focal #epilepsy

Association of triage #hypothermia with in-hospital mortality among patients in the emergency department with suspected #sepsis

To identify if triage hypothermia (<36.0 °C) among emergency department (ED) encounters with sepsis are independently associated with mortality.. ..Of 1.2 billion ED encounters (95% confidence interval [CI] 1.0–1.3 billion), 3.1 million (95% CI 2.7–3.5 million) met the explicit sepsis definition; 7.4% (95% CI 75.2–9.7%) had triage hypothermia. The adjusted odds ratio (aOR) for hypothermia for in-hospital mortality was 6.82 (95% CI 3.08–15.22). The severe … Continue reading Association of triage #hypothermia with in-hospital mortality among patients in the emergency department with suspected #sepsis

Association of #Menopausal Hormone Therapy With Breast #Cancer Incidence and Mortality During Long-term Follow-up of the Women’s Health Initiative Randomized Clinical Trials

In the trial involving 16 608 women with a uterus, 8506 were randomized to receive 0.625 mg/d of conjugated equine estrogen (CEE) plus 2.5 mg/d of medroxyprogesterone acetate (MPA) and 8102, placebo. In the trial involving 10 739 women with prior hysterectomy, 5310 were randomized to receive 0.625 mg/d of CEE alone and 5429, placebo. The CEE-plus-MPA trial was stopped in 2002 after 5.6 years’ median intervention … Continue reading Association of #Menopausal Hormone Therapy With Breast #Cancer Incidence and Mortality During Long-term Follow-up of the Women’s Health Initiative Randomized Clinical Trials

The temporal association between incident late‐life #depression and incident #dementia

There is an established association between depression and subsequent dementia. The present study examined temporal associations between incident late‐life depression and subsequent dementia, also considering age and sex.. ..Incident depression was associated with a higher risk of subsequent dementia (incidence rate ratios (IRR) adjusted for age and sex: IRR = 1.58, 95% CI = 1.51‐1.64). The strongest association was found for the shortest interval of … Continue reading The temporal association between incident late‐life #depression and incident #dementia

Statin adherence and risk of all-cause, cancer, and cardiovascular mortality among dyslipidemia patients: A time-dependent analysis

Results have been mixed and uncertainty still remains regarding the impact of statin adherence on premature deaths. Thus, we investigated the association between statin adherence and risks of all-cause, cancer, and cardiovascular mortality among dyslipidemia patients in South Korea.. We used data from the National Health Insurance Service (NHIS) National Sample Cohort for the years 2003-2013, which included data on 107,954 middle-aged and elderly dyslipidemia … Continue reading Statin adherence and risk of all-cause, cancer, and cardiovascular mortality among dyslipidemia patients: A time-dependent analysis
