More attention is needed to address the mental health of workers supporting adults with intellectual disabilities as they continue their essential work during the pandemic.Recently palladium catalysts have been discovered that enable the directing-group-free C-H activation of arenes without requiring an excess of the arene substrate, thereby enabling methods for the late-stage modification of complex organic molecules. The key to success has been the use of two complementary ligands, an N-acyl amino acid and an N-heterocycle. Detailed experimental and computational mechanistic studies on the dual-ligand-enabled C-H activation of arenes have led us to identify the catalytically active species and a transition state model that explains the exceptional activity and selectivity of these catalysts. These findings are expected to be highly useful for further method development using this powerful class of catalysts.

The aim of the study was to investigate the dynamics of cytomegalovirus (CMV) replication and CMV-specific immune response recovery after antiretroviral treatment (ART) initiation in patients with advanced HIV infection.

A prospective observational study of patients with HIV infection and CD4 counts of <100 cells/µL was carried out (September 2015 to July 2018). HIV viral load (VL), CD4 count and CMV VL were determined by quantitative polymerase chain reaction (PCR) at baseline and at 4, 12, 24 and 48weeks, and CMV-specific immune response was determined by QuantiFERON-CMV assay at baseline and 48weeks. All patients were started on ART but only those with CMV end-organ disease (EOD) received anti-CMV treatment.

Fifty-three patients with a median age of 43.6 [interquartile range (IQR) 36.7-52.4] years were included in the study. At baseline, the median CD4 count was 30 cells/µL (IQR 20-60 cells/µL) and the median HIV VL was 462000 HIV-1 RNA copies/mL (IQR 186000-1300000 copies/mL). At baseline, 32% paal recovery through ART is enough to suppress CMV viraemia, without an increased risk of CMV EOD. The prevalence of a CMV-specific immune response was high and endured over time.Internationally, parents of children with intellectual and developmental disabilities have historically engaged in advocacy leading to compulsory education for their children. However, few parents have reported civic engagement. Although empowerment is related to parent advocacy, it is unclear whether empowerment relates to civic engagement. Thus, our study examined parent and child correlates of empowerment and civic engagement, and the relation between empowerment and civic engagement among 235 parents of children with intellectual and developmental disabilities across five states in the United States. NMS-P937 Gender and special education knowledge were significant correlates of empowerment and civic engagement. There was a significant positive correlation between empowerment and civic engagement. Implications regarding future research and ways to promote parent empowerment and civic engagement are discussed.

The role of neurohormonal inhibition in chronic heart failure (HF) is well established. There are limited data on the effect of up-titration of renin-angiotensin inhibitors (RASi) and beta-blockers (BBs) on clinical outcomes of patients with worsening HF across the left ventricular ejection fraction (LVEF) spectrum.

We analysed data from 2345 patients from BIOSTAT-CHF (80.9% LVEF <40%), who completed a 3-month up-titration period after recent worsening of HF. Patients were classified by achieved dose (% of recommended) ≥100%, 50-99%, 1-49%, and none. Recurrent event analysis using joint and shared frailty models was used to examine the association between RASi/BB dose and all-cause and HF hospitalizations. In the 21 months following up-titration, 512 patients died and 879 (37.5%) had ≥1 hospitalization. RASi up-titration was associated, incrementally, with reduced risk of all-cause hospitalization at all achieved dose levels compared to no treatment [hazard ratio (95% confidence interval) ≥100% 0.60 (0.49-0.74), P < 0.001; 50-99% 0.56 (0.46-0.68), P < 0.001; 1-49% 0.71 (0.59-0.86), P < 0.001]. This association was consistent up to an LVEF of 49% (P < 0.001), and when considering only HF hospitalizations. Up-titration of BBs was associated with fewer all-cause hospitalizations only when LVEF was <40% (overall P < 0.001), but with more HF hospitalizations when LVEF was ≥50%. Up-titration of both RASi/BBs was associated with lower mortality in LVEF up to 49%.

After recent worsening of HF, up-titration of RASi and BBs was associated with a better prognosis in patients with LVEF ≤49%. Up-titration of BBs was associated with a greater risk of HF hospitalization when LVEF was ≥50%.

After recent worsening of HF, up-titration of RASi and BBs was associated with a better prognosis in patients with LVEF ≤49%. Up-titration of BBs was associated with a greater risk of HF hospitalization when LVEF was ≥50%.Climate change affects global agricultural production and threatens food security. Faster phenological development of crops due to climate warming is one of the main drivers for potential future yield reductions. To counter the effect of faster maturity, adapted varieties would require more heat units to regain the previous growing period length. In this study, we investigate the effects of variety adaptation on global caloric production under four different future climate change scenarios for maize, rice, soybean, and wheat. Thereby, we empirically identify areas that could require new varieties and areas where variety adaptation could be achieved by shifting existing varieties into new regions. The study uses an ensemble of seven global gridded crop models and five CMIP6 climate models. We found that 39% (SSP5-8.5) of global cropland could require new crop varieties to avoid yield loss from climate change by the end of the century. At low levels of warming (SSP1-2.6), 85% of currently cultivated land can draw from existing varieties to shift within an agro-ecological zone for adaptation. The assumptions on available varieties for adaptation have major impacts on the effectiveness of variety adaptation, which could more than half in SSP5-8.5. The results highlight that region-specific breeding efforts are required to allow for a successful adaptation to climate change.
