The seasonal cycle of respiratory viral diseases has been widely recognized for thousands of years, as annual epidemics of the common cold and influenza disease hit the human population like clockwork in the winter season in temperate regions. Moreover, epidemics caused by viruses such as severe acute respiratory syndrome coronavirus (SARS-CoV) and the newly emerging… Continue reading Seasonality of Respiratory Viral Infections
Chronic #obstructive pulmonary disease and lung cancer incidence in never smokers: a cohort study
There has been limited evidence for the association between chronic obstructive pulmonary disease (COPD) and the incidence of lung cancer among never smokers. We aimed to estimate the risk of lung cancer incidence in never smokers with COPD, and to compare it with the risk associated with smoking. This cohort study involved 338 548 subjects, 40… Continue reading Chronic #obstructive pulmonary disease and lung cancer incidence in never smokers: a cohort study
Comparison of dietary macronutrient patterns of 14 popular named dietary programmes for #weight and cardiovascular risk factor reduction in adults: systematic review and network meta-analysis of randomised trials
..Compared with usual diet, low carbohydrate and low fat diets had a similar effect at six months on weight loss (4.63 v 4.37 kg, both moderate certainty) and reduction in systolic blood pressure (5.14 mm Hg, moderate certainty v 5.05 mm Hg, low certainty) and diastolic blood pressure (3.21 v 2.85 mm Hg, both low… Continue reading Comparison of dietary macronutrient patterns of 14 popular named dietary programmes for #weight and cardiovascular risk factor reduction in adults: systematic review and network meta-analysis of randomised trials
Timing of #Endoscopy for Acute Upper Gastrointestinal #Bleeding
To evaluate whether urgent endoscopy improves outcomes in patients predicted to be at high risk for further bleeding or death, we randomly assigned patients with overt signs of acute upper gastrointestinal bleeding and a Glasgow–Blatchford score of 12 or higher (scores range from 0 to 23, with higher scores indicating a higher risk of further… Continue reading Timing of #Endoscopy for Acute Upper Gastrointestinal #Bleeding
Estimates of the severity of #coronavirus disease 2019: a model-based analysis
Using data on 24 deaths that occurred in mainland China and 165 recoveries outside of China, we estimated the mean duration from onset of symptoms to death to be 17·8 days (95% credible interval [CrI] 16·9–19·2) and to hospital discharge to be 24·7 days (22·9–28·1). In all laboratory confirmed and clinically diagnosed cases from mainland… Continue reading Estimates of the severity of #coronavirus disease 2019: a model-based analysis
Plant‐based and animal‐based low‐carbohydrate #diets and risk of #hepatocellular carcinoma among US men and women
Little is known about the role of low‐carbohydrate diets (LCDs) in the development of hepatocellular carcinoma (HCC).. ..During 3,664,769 person years of follow‐up, there were 156 incident HCC cases. Although there were no associations between overall or animal‐based LCD score and risk of HCC, plant‐based LCD score was inversely associated with HCC risk (HR: 0.83;… Continue reading Plant‐based and animal‐based low‐carbohydrate #diets and risk of #hepatocellular carcinoma among US men and women
A Randomized, Controlled Trial of #Liraglutide for Adolescents with #Obesity
Liraglutide was superior to placebo with regard to the change from baseline in the BMI standard-deviation score at week 56 (estimated difference, −0.22; 95% confidence interval [CI], −0.37 to −0.08; P=0.002). A reduction in BMI of at least 5% was observed in 51 of 113 participants in the liraglutide group and in 20 of 105… Continue reading A Randomized, Controlled Trial of #Liraglutide for Adolescents with #Obesity
Loss of life expectancy from air #pollution compared to other risk factors: a worldwide perspective
..We used a data-informed atmospheric model to calculate worldwide exposure to PM2.5 and ozone pollution, which was combined with the GEMM to estimate disease-specific excess mortality and loss of life expectancy (LLE) in 2015. Using this model, we investigated the effects of different pollution sources, distinguishing between natural (wildfires, aeolian dust) and anthropogenic emissions, including… Continue reading Loss of life expectancy from air #pollution compared to other risk factors: a worldwide perspective
#IL-4 induces M2 macrophages to produce sustained #analgesia via opioids
IL-4 is a pleiotropic antiinflammatory cytokine, which can be neuroprotective after nervous system injury. The beneficial actions of IL-4 are thought to result from the blunting of action of inflammatory mediators, such as proinflammatory cytokines. Here, we demonstrate that IL-4 induces M2 macrophages to continuously produce opioid peptides and ameliorate pain. IL-4 application at injured… Continue reading #IL-4 induces M2 macrophages to produce sustained #analgesia via opioids
