Older gay men experience an elevated prevalence of adverse health conditions that may be compounded by age-related deterioration. Some of these conditions may be ameliorated by regular adherence to physical activity (PA). However, many gay men participate in less PA than their age-matched heterosexual counterparts. With a focus on gay men aged 60 and over, the aims of this review were to examine the evidence for older gay men's engagement with PA and the research approaches used to describe this group. A systematic search of six academic databases (Academic Search Premier, Cinahl, PubMed, Sport Discus, APA PsychInfo and APA PsychArticles) generated 23 papers from 1970 to 2020 that focused on older gay men's engagement with PA. Although surveys were well represented in the literature, further studies utilising qualitative methodological frameworks have the potential to inform targeted interventional programs aimed at reducing less health disparities. The value of PA in older adults lies principally in improved performance of activities of daily living, independent living, increased longevity, decreased cognitive decline and improved mental well-being.Perovskite light-emitting diodes (PeLEDs) are promising candidates for display and solid-state lighting, due to their tunable colors, high conversion efficiencies, and low cost. However, the performance of blue PeLEDs is far inferior to that of the near-infrared, red, and green counterparts. Here, the fabrication of pure-blue PeLEDs with an emission peak at 475 nm, a peak external quantum efficiency of 10.1%, and a maximum luminance of 14 000 cd m-2 is demonstrated by tailoring the compositions of perovskites. The pure-blue electroluminescence is achieved by simultaneous addition of rubidium and chlorine ions into CsPbBr3 and incorporation of phenylethylammonium chloride forms quasi-2D hybrid perovskites. The combination of these composition engineering results in blueshifted emissions without reducing the quantum yield. The judicious alloying is shown to be critical to result in the better morphology with suppressed current leakage and enhanced light outcoupling.In the present study, we aim to investigate the effects of aerobic physical training on perivascular adipose tissue (PVAT)-induced microvascular dysfunction of the femoral artery in obese mice. Microvascular reactivity was evaluated in control sedentary (c-SD), obese sedentary (o-SD) and obese trained (o-TR) male mice (C57BL6/JUnib), in the absence (PVAT-) or the presence (PVAT+) of femoral artery PVAT. We also analyzed protein expression, vascular nitric oxide (NO) production and reactive oxygen species (ROS) generation in PVAT. selleck chemicals llc The blood glucose, triglycerides and total cholesterol levels were increased in the o-SD group, when compared with the c-SD group. The maximal responses and the potency to acetylcholine (ACh) were decreased in PVAT+ compared with PVAT- rings in the o-SD group, accompanied by a decrease in vascular protein expression of peNOSSer1177 , Cu/Zn-SOD, leptin receptor (Ob-R) and adiponectin receptor (AdipoR1). The protein expression of leptin increased and that of adiponectin decreased in PVAT. Additionally, vascular NO production was reduced and ROS generation was enhanced in PVAT in the o-SD group. Aerobic exercise training was effective for normalizing ACh relaxation response, vascular NO production and ROS generation in the o-TR group. It partially re-established the vascular protein expression of peNOSSer1177 and the PVAT leptin; normalized the vascular Cu/Zn-SOD and AdipoR1 protein expressions. In obese sedentary mice, the presence of PVAT is involved in the process of microvascular dysfunction of the femoral artery in a pathway associated with increased inflammation and ROS generation. The aerobic exercise training normalized the vascular response, the NO production and/or bioavailability and oxidative stress, with improved vascular expressions of Cu/Zn-SOD, peNOSser1177 , and AdipoR1.Diarrhoea is an adverse drug reaction of the angiotensin receptor neprilysin inhibitor (ARNI) sacubitril + valsartan. It was also described with olmesartan and more recently with other angiotensin receptor blockers. The study was performed to compare diarrhoea reports in pharmacovigilance databases with sacubitril + valsartan and valsartan. The study used reports of diarrhoea with the ARNI sacubitril + valsartan registered first in the French PharmacoVigilance Database (FPVD) and second in Vigibase®, the WHO Global Individual Case Safety Report database. After description of the main characteristics, disproportionality analyses were performed. Results are reported as reporting odds ratios (ROR) with 95% confidence interval. We found 29 reports of diarrhoea with sacubitril + valsartan in the FPVD and 686 in Vigibase®. With sacubitril + valsartan, diarrhoea occurred more frequently in males around 70 years with a median delay of 3 days. With valsartan, diarrhoea occurred more frequently in females around 68 years with a median delay of 0.5 days. In the FPVD, a significant association was found with sacubitril + valsartan in comparison with valsartan alone before (ROR = 8.78 [5.19-14.85]) and after (ROR = 11.19 [5.89-21.25]) exclusion of concomitant drugs known to be associated with diarrhoea. A significant association was also found in Vigibase® after adjustment on age, sex, reporter and its location (ROR = 1.31 [1.14-1.50]). Diarrhoea reported with sacubitril + valsartan has marked differences in gender, delay of occurrence and frequency of reporting in comparison with diarrhoea with valsartan. From a pharmacodynamic point of view, these results suggest a specific role of sacubitril in diarrhoea.Hemidiaphragm paralysis (HP) is a potential complication of cardiac surgery. While most patients are either asymptomatic or have mild symptoms, some are at risk of developing life-threatening hypercapnia. We present a case of a patient who developed HP after tricuspid valve replacement. Diaphragm plication was deferred due to underlying comorbidities, but over time she developed severe hypercapnic respiratory failure requiring intensive care unit admission. Chronic noninvasive ventilation therapy (NIV) was initiated, which improved her symptoms and hypercapnia and prevented further hospitalizations. For patients with iatrogenic HP unable to undergo diaphragm plication, Pulmonology referral for initiation of NIV should be strongly considered.We read with interest the observational study by Sanchez et al. regarding the clinical course and risk factors for infections in severe forms of alcohol-related liver disease1 . This study re-establishes the well-known fact that risk of infection is correlated to severity of liver dysfunction in patients with cirrhosis.

Dyslipidemia has been observed in patients with coronavirus disease 2019 (COVID-19). This study aimed to investigate blood lipid profiles in patients with COVID-19 and to explore their predictive values for COVID-19severity.

A total of 142 consecutive patients with COVID-19 were included in this single-center retrospective study. Blood lipid profile characteristics were investigated in patients with COVID-19 in comparison with 77 age- and gender-matched healthy subjects, their predictive values for COVID-19severity were analyzed by using multivariable logistic regression analysis, and their prediction efficiencies were evaluated by using receiver operator characteristic (ROC) curves.

There were 125 and 17 cases in the non-severe and severe groups, respectively. Total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and apolipoprotein A1 (ApoA1) gradually decreased across the groups in the following order healthy controls, non-severe group, and severe group. ApoA1 was identified as an independent risk factor for COVID-19severity (adjusted odds ratio [OR] 0.865, 95% confidence interval [CI] 0.800-0.935, p<0.001), along with interleukin-6 (IL-6) (adjusted OR 1.097, 95% CI 1.034-1.165, p=0.002). ApoA1 exhibited the highest area under the ROC curve (AUC) among all single markers (AUC 0.896, 95% CI 0.834-0.941); moreover, the risk model established using ApoA1 and IL-6 enhanced prediction efficiency (AUC 0.977, 95% CI 0.932-0.995).

Blood lipid profiles in patients with COVID-19 are quite abnormal compared with those in healthy subjects, especially in severe cases. Serum ApoA1may represent a good indicator for predicting the severity of COVID-19.

As stated in the manuscript, 42(30%) patients were already infected upon admission.Allogeneic hematopoeitic cell transplantation (allo-HCT) is the only curative treatment for myelofibrosis (MF). We evaluate the impact of various factors on survival outcomes post-transplant in MF. Data of 89 consecutive MF patients (primary 47%) who underwent allo-HCT between 2005 and 2018 was evaluated. Fifty-four percent patients had received JAK1/2 inhibitors (JAKi) pre-HCT. The median CD34 count was 7.1x106 cells/kg. Graft failure was seen in 10% of the patients. Grade 3-4 acute GVHD (aGVHD) and moderate/severe chronic graft versus host disease (cGVHD) occurred in 24% and 40% patients, respectively. Two-year overall survival (OS) and relapse free survival (RFS) were 51% and 43%, respectively. Cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) at 2 years were 11% and 46%, respectively. Higher CD34 cell dose (≤5 × 106 cells/kg vs 5-9 or ≥9 × 106 cells/kg) and lower pre-HCT ferritin ( less then /=1000 ng/ml) were associated with better OS, RFS and lower NRM. Grade 3-4 aGVHD was associated with higher NRM. Use of pre-transplant JAKi was associated with lower incidence of grade 3-4 aGVHD. In summary, higher CD34 cell dose is associated with better allo-HCT outcomes in MF and pre-HCT JAKi use is associated with reduced risk of severe aGVHD. These two modifiable parameters should be considered during allo-HCT for MF.

To describe the results of orthogonal plating (OP) as a treatment for fractures of the radius and ulna in toy-breed dogs.

The medical records (June 2011 to April 2019) of toy-breeds in which the OP technique using non-locking cuttable plates was employed to treat radial and ulnar fractures were reviewed. The inclusion criteria included a bodyweight of 3.5kg or less, fracture of the diaphysis of the radius and ulna of one or both forelimbs, and the availability of follow-up radiographs. Revision surgeries were also included.

Fifteen limbs that underwent initial fracture repair and five that underwent revision surgery met the inclusion criteria. The radial and ulnar fractures healed in 19 limbs at the final follow-up. Synostosis of the radius and ulna at the fracture sites was observed in one limb. Re-fracture after cranial plate removal was observed in one case. All dogs exhibited successful return of normal limb function at the final clinical and radiographic follow-up (mean, 104.7 ± 67.1 days; median, 79.
