Moreover, we find that it is applicable to various cell line development protocols. This approach can simplify development protocols and shorten timelines while ensuring clonal derivation with high confidence.

There are two distinctive acral manifestations of COVID-19 embodying disparate clinical phenotypes. One is perniosis occurring in mildly symptomatic patients, typically children and young adults; the second is the thrombotic retiform purpura of critically ill adults with COVID-19.

To compare the clinical and pathological profiles of these two different cutaneous manifestations of COVID-19.

We compared the light microscopic, phenotypic, cytokine and SARS-CoV-2 protein and RNA profiles of COVID-19-associated perniosis with that of thrombotic retiform purpura in critical patients with COVID-19.

Biopsies of COVID-19-associated perniosis exhibited vasocentric and eccrinotropic T-cell- and monocyte-derived CD11c

dendritic cell infiltrates. Both COVID-associated and idiopathic perniosis showed striking expression of the type I interferon-inducible myxovirus resistance protein A (MXA), an established marker for type I interferon signalling in tissue. SARS-CoV-2 RNA, interleukin-6 and caniosis represents a virally triggered exaggerated immune reaction with significant type I interferon signaling. This is important to SARS-CoV-2 eradication and has implications in regards to a more generalized highly inflammatory response. We hypothesize that in the thrombotic retiform purpura of critically ill patients with COVID-19, the vascular thrombosis in the skin and other organ systems is associated with a minimal interferon response. This allows excessive viral replication with release of viral proteins that localize to extrapulmonary endothelium and trigger extensive complement activation.

The burden of poor sexual and reproductive health (SRH) worldwide is substantial, disproportionately affecting those living in low- and middle-income countries. Targeted client communication (TCC) delivered via mobile devices (MD) (TCCMD) may improve the health behaviours and service use important for sexual and reproductive health.

To assess the effects of TCC via MD on adolescents' knowledge, and on adolescents' and adults' sexual and reproductive health behaviour, health service use, and health and well-being.

In July/August 2017, we searched five databases including The Cochrane Central Register of Controlled Trials, MEDLINE and Embase. We also searched two trial registries. A search update was carried out in July 2019 and potentially relevant studies are awaiting classification.

We included randomised controlled trials of TCC via MD to improve sexual and reproductive health behaviour, health service use, and health and well-being. Eligible comparators were standard care or no intervention, non-diefits of TCC delivered by mobile devices. Given the sensitivity and stigma associated with sexual and reproductive health future studies should measure unintended consequences, such as partner violence or breaches of confidentiality.

TCCMD may improve some outcomes but the evidence is of low certainty. The effect on most outcomes is uncertain/unknown due to very low certainty evidence or lack of evidence. High quality, adequately powered trials and cost effectiveness analyses are required to reliably ascertain the effects and relative benefits of TCC delivered by mobile devices. find more Given the sensitivity and stigma associated with sexual and reproductive health future studies should measure unintended consequences, such as partner violence or breaches of confidentiality.Here we report the first record of the Mayan cichlid, Mayaheros urophthalmus, occurring on an offshore island 70 km from the mainland, the most distant record from the mainland to date. Specimens were collected during several ichthyological surveys on the island of Guanaja, Honduras in November 2019. Mayan cichlids are euryhaline fishes that perform very well in fresh, brackish and marine waters. It has been hypothesized that their high tolerance to salinity and potential of using costal waterways has facilitated the colonization and expansion of M. urophthalmus.

Severe acute respiratory syndrome coronavirus-2 has caused a pandemic of coronavirus disease (COVID-19) with many patients developing hypoxic respiratory failure. Corticosteroids reduce the time on mechanical ventilation, length of stay in the intensive care unit and potentially also mortality in similar patient populations. However, corticosteroids have undesirable effects, including longer time to viral clearance. Clinical equipoise on the use of corticosteroids for COVID-19 exists.

The COVID STEROID trial is an international, randomised, stratified, blinded clinical trial. We will allocate 1000 adult patients with COVID-19 receiving ≥10L/min of oxygen or on mechanical ventilation to intravenous hydrocortisone 200mg daily vs placebo (0.9% saline) for 7days. The primary outcome is days alive without life support (ie mechanical ventilation, circulatory support, and renal replacement therapy) at day 28. Secondary outcomes are serious adverse reactions at day 14; days alive without life support at day 90; days alive and out of hospital at day 90; all-cause mortality at day 28, day 90, and 1year; and health-related quality of life at 1year. We will conduct the statistical analyses according to this protocol, including interim analyses for every 250 patients followed for 28days. The primary outcome will be compared using the Kryger Jensen and Lange test in the intention to treat population and reported as differences in means and medians with 95% confidence intervals.

The COVID STEROID trial will provide important evidence to guide the use of corticosteroids in COVID-19 and severe hypoxia.

Professional musicians show a high prevalence of musculoskeletal pain, but information is limited about prevalence of pain compared to the general populations.

Our cross-sectional epidemiological study compared the prevalence of musculoskeletal pain between professional orchestra musicians and the working population in Finland.

Musicians with a permanent contract with all domestic professional symphony and philharmonic orchestras and a population sample of the workforce in Finland completed questionnaires including the same questions on musculoskeletal pain and on various other issues. Cross-sectional data from two population-based and two orchestra-musician studies were analysed by logistic regression model adjusting for confounding factors.

In 2002, 345 musicians completed questionnaires (40% response rate), and in 2010, 195 (23%). The Health 2000 study sample comprised 5956 employed participants and in 2011, 5942. Musicians reported, in 2002 and in 2010, back pain during the past 30 days more often than did controls, 39% versus 27%, adjusted odds ratio (95% confidence interval, CI) 1.
