f hospitalization relative to field hockey.

The findings of this study suggest that ice hockey was more associated with injuries to the head and neck as well as with concussions and internal organ injury compared to field hockey. However, ice hockey was not associated with increased risk of hospitalization relative to field hockey.

The SARS-CoV-2 omicron variant of concern was identified in South Africa in November, 2021, and was associated with an increase in COVID-19 cases. We aimed to assess the clinical severity of infections with the omicron variant using S gene target failure (SGTF) on the Thermo Fisher Scientific TaqPath COVID-19 PCR test as a proxy.

We did data linkages for national, South African COVID-19 case data, SARS-CoV-2 laboratory test data, SARS-CoV-2 genome data, and COVID-19 hospital admissions data. For individuals diagnosed with COVID-19 via TaqPath PCR tests, infections were designated as either SGTF or non-SGTF. The delta variant was identified by genome sequencing. Using multivariable logistic regression models, we assessed disease severity and hospitalisations by comparing individuals with SGTF versus non-SGTF infections diagnosed between Oct 1 and Nov 30, 2021, and we further assessed disease severity by comparing SGTF-infected individuals diagnosed between Oct 1 and Nov 30, 2021, with delta variant-infectean Society of Laboratory Medicine, Africa Centers for Disease Control and Prevention, the Bill & Melinda Gates Foundation, the Wellcome Trust, and the Fleming Fund.

In relatives of patients dying in intensive care units (ICUs), inadequate team support can increase the prevalence of prolonged grief and other psychological harm. We aimed to evaluate whether a proactive communication and support intervention would improve relatives’ outcomes.

We undertook a prospective, multicentre, cluster randomised controlled trial in 34 ICUs in France, to compare standard care with a physician-driven, nurse-aided, three-step support strategy for families throughout the dying process, following a decision to withdraw or withhold life support. Inclusion criteria were relatives of patients older than 18 years with an ICU length of stay 2 days or longer. Participating ICUs were randomly assigned (11 ratio) into an intervention cluster and a control cluster. The randomisation scheme was generated centrally by a statistician not otherwise involved in the study, using permutation blocks of non-released size. In the intervention group, three meetings were held with relatives a family conferd the median PG-13 score was significantly lower in the intervention group than in the control group (19 [IQR 14-26] vs 21 [15-29], mean difference 2·5, 95% CI 1·04-3·95).

Among relatives of patients dying in the ICU, a physician-driven, nurse-aided, three-step support strategy significantly reduced prolonged grief symptoms.

French Ministry of Health.Disasters are an important public health issue; however, there is scarce evidence to date on what happens when communities and populations experience more than one disaster. This scoping review identifies literature on the effects of multiple disasters published until Aug 2, 2021, 1425 articles were identified, of which 150 articles were included. We analysed direct and indirect public health implications of multiple disasters. Our analysis suggests that exposure to multiple disasters can affect mental health, physical health, and wellbeing, with some evidence that the potential risks of multiple disaster exposure exceed those of single disaster exposure. We also identified indirect public health implications of multiple disaster exposure, related to changes in health-care facilities, changes in public risk perception, and governmental responses to multiple disasters. We present findings on community recovery and methodological challenges to the study of multiple disasters, and directions for future research.

Management of elderly patients with hepatocellular carcinoma (HCC) has become a major concern. Some data suggest that cryoablation improves the outcomes of elderly patients with HCC, but its efficacy and safety remain unknown. This study aimed to evaluate and compare the efficacy and safety of percutaneous cryoablation with those of radiofrequency ablation (RFA) for elderly HCC patients.

In all, 223 patients with small HCC aged ≥70years, treatment-naïve, without metastasis were enrolled and randomized into a cryoablation group (n=112) or a RFA (n=111) group from July 2015 to October 2018. The primary endpoint was local tumour progression (LTP) at 3years after treatment. The secondary endpoints including overall survival (OS), tumour-free survival (TFS), LTP and safety were analysed for these two groups after both treatments.

LTP rates at 1-, 3- and 5-year were 12%, 17% and 20% for cryoablation and 17%, 18% and 21% for RFA respectively (P=.735). For lesions >3cm in diameter, LTP rates at 1- and 3-year were 13% and 22% in cryoablation group and 22% and 42% respectively, in the RFA group (P=.039). The 1-, 3- and 5-year OS rates were 90, 75% and 62% for cryoablation and 90%, 68% and 63% for RFA respectively (P=.331). The 1-, 3- and 5-year TFS rates were 59%, 32% and 25% in the cryoablation and 59%, 28% and 20% in the RFA respectively (P=.309). Major complications occurred in 6 patients (5%) following cryoablation and 6 patients (6%) following RFA (P=.886).

Cryoablation and RFA had similar LTP in elderly patients with small HCC and this study failed to meet the primary endpoint, although for a relatively large early-stage HCC the LTP rate after cryoablation was significantly lower than that after RFA.

Thermo-electrochemical cells, compared to the widely investigated thermoelectric generators, show greater potential in wearable applications due to the higher voltage output from low-grade heat and the increased option range of cheap and flexible electrode/electrolyte materials. A wearable photo-thermo-electrochemical cell (PTEC) is first fabricated here through the introduction of a polymer-based flexible photothermal film as a solar-absorber and hot electrode, followed by a systematic investigation of wearable device design. The as-prepared PTEC single device shows outstanding output voltage and current density of 15.0 mV and 10.8 A m-2 and 7.1 mV and 8.57 A m-2 , for the device employing p-type and n-type gel electrolytes, respectively. Benefiting from the equivalent performance in current density, a series connection containing 18 pairs of p-n PTEC devices is effectively made, which can harvest solar energy and charge supercapacitors to above 250 mV (1 sun solar illumination). Meanwhile, a watch-strap shaped flexible PTEC (eight p-n pairs) that can be worn on a wrist is fabricated and the realized voltage above 150 mV under light shows the potential for use in wearable applications.4D bioprinting is promising to build cell-laden constructs (bioconstructs) with complex geometries and functions for tissue/organ regeneration applications. The development of hydrogel-based 4D bioinks, especially those allowing living cell printing, with easy preparation, defined composition, and controlled physical properties is critically important for 4D bioprinting. Here, a single-component jammed micro-flake hydrogel (MFH) system with heterogeneous size distribution, which differs from the conventional granular microgel, has been developed as a new cell-laden bioink for 4D bioprinting. This jammed cytocompatible MFH features scalable production and straightforward composition with shear-thinning, shear-yielding, and rapid self-healing properties. As such, it can be smoothly printed into stable 3D bioconstructs, which can be further cross-linked to form a gradient in cross-linking density when a photoinitiator and a UV absorber are incorporated. After being subject to shape morphing, a variety of complex bioconstructs with well-defined configurations and high cell viability are obtained. Based on this system, 4D cartilage-like tissue formation is demonstrated as a proof-of-concept. The establishment of this versatile new 4D bioink system may open up a number of applications in tissue engineering.

Disparities in salary and advancement of emergency medicine (EM) faculty by race and gender have been consistently demonstrated for over three decades. Prior studies have largely focused on individual-level solutions. To identify systems-based interventions, the Society for Academic Emergency Medicine (SAEM) formed the Research Equity Task Force in 2018 with members from multiple academies (the Academy of Academic Chairs in Emergency Medicine [AACEM], the Academy of Academic Administrators in Emergency Medicine [AAAEM], the Academy for Women in Academic Emergency Medicine [AWAEM], and the Academy for Diversity and Inclusion in Emergency Medicine [ADIEM]) and sought recommendations from EM departmental leaders.

The task force conducted interviews containing both open-ended narrative and closed-ended questions in multiple phases. Phase 1 included a convenience sample of chairs of EM departments across the United States, and phase 2 included vice-chairs and other faculty who lead promotion and advancement. Tpromotion and advancement, and reduce disparities in the AEM workforce. These recommendations have been endorsed by SAEM, AACEM, AWAEM, ADIEM, and AAAEM.

These recommendations for AEM departments have the potential to increase structured mentorship programs, improve equity in promotion and advancement, and reduce disparities in the AEM workforce.

Understanding gene regulatory networks is essential to deciphering plant metabolic pathways, including lipid metabolism. Here, we take advantage of a growing collection of gene expression datasets to predict transcription factors (TFs) associated with the control of Camelina lipid metabolism. We identified approximately 350 TFs highly co-expressed with lipid-related genes (LRGs). These TFs are highly represented in the MYB, AP2/ERF, bZIP, and bHLH families, including a significant number of homologs of well-known Arabidopsis lipid and seed developmental regulators. After prioritizing the top 22 TFs for further validation, we identified DNA-binding sites and predicted target genes for 16 out of the 22 TFs tested using DNA affinity purification followed by sequencing (DAP-seq). Enrichment analyses of targets supported the co-expression prediction for most TF candidates, and the comparison to Arabidopsis revealed some common themes, but also aspects unique to Camelina. Within the top potential lipid regulators, we identified CsaMYB1, CsaABI3AVP1-2, CsaHB1, CsaNAC2, CsaMYB3, and CsaNAC1 as likely involved in the control of seed fatty acid elongation and CsaABI3AVP1-2 and CsabZIP1 as potential regulators of the synthesis and degradation of triacylglycerols (TAGs), respectively. Altogether, the integration of co-expression data and DNA-binding assays permitted us to generate a high-confidence and short list of Camelina TFs involved in the control of lipid metabolism during seed development.
