on.Understanding the role of H2 S in host defense mechanisms against RNA viruses may provide opportunities for the development of antivirals to combat viral infections. Here, we have developed a green-emitting fluorogenic probe, which exhibits a large fluorescence response at 520 nm (>560-fold) when treated with 100 μM H2 S for 1 h. It is highly selective for H2 S over biothiols (>400-fold F/F0 ) and has a detection limit of 12.9 nM. We demonstrate the application of the probe for endogenous H2 S detection in vivo for the understanding of its roles in antiviral host defense. Such virus-induced H2 S inhibits viral replication by reducing gene expression of RNA-dependent RNA polymerase (RdRp) and coat protein (CP). RCM-1 ic50 Additionally, a H2 S donor GYY4137 showed significantly antiviral activity as ribavirin, a broad-spectrum drug against RNA viruses. Furtherly, we propose a possible molecular mechanism for the TMV-induced H2 S biogenesis. This work provides a proof-of-principle in support of further studies identifying endogenous H2 S and its donors as potential antivirals toward RNA viruses.

The aim of this prospective cohort study was to identify the predictors of the development and persistence of musculoskeletal pain (MSKP) in older people.

Participants comprised 431 community-dwelling older people aged 70+ years. Demographic, anthropometric, balance, mobility, cognitive function, psychological status and physical activity level measures were obtained at baseline. Participants were asked about the presence of MSKP in the neck/back, hip, knee/leg and/or feet at baseline and two-year follow-up. Logistic regression analyses were performed to identify predictors of the development and persistence of MSKP at two-year follow-up.

Of 179 participants who reported no MSKP at baseline, 84 (46.9%) reported MSKP at two-year follow-up, which was associated with a higher body mass index (odds ratio (OR) 1.10, 95% confidence interval (CI) 1.02-1.18), more reported depressive symptoms (OR 1.30, 95% CI 1.05-1.61) and lower physical activity levels (OR 0.92, 95% CI 0.84-1.00) at baseline. Of 252 participasults highlight the importance of weight control, strategies to improve mental wellbeing and an active lifestyle for pain management among older people.

Characterisation of a range of naturally occurring HMTs and subsequent protein engineering led to HMT variants capable of synthesising ethyl, propyl, and allyl analogues of SAM. Notably, HMTs do not depend on chemical synthesis of methionine analogues, as required by methionine adenosyltransferases (MATs). However, at the moment MATs have a much broader substrate scope than the HMTs. Herein we provide an overview of the discovery and engineering of promiscuous HMTs and how these strategies will pave the way towards a toolbox of HMT variants for versatile chemo- and regioselective biocatalytic alkylations.Influenza vaccination is an important preventative health measure in the elderly and those with medical comorbidities. It has been shown to reduce hospitalisations, cardiovascular and respiratory complications. A significant proportion of patients admitted to general medicine are eligible for opportunistic inpatient influenza vaccination. This study explores the cost-effectiveness of such a strategy in reducing subsequent healthcare utilisation costs.Lung resection in patients aged ≥80 years is considered high risk and contributes to the low rates of resection in this population. This review of 79 octogenarians who underwent curative surgery for non-small-cell lung cancer demonstrated no intraoperative mortality, 30-day mortality of 1.3% and 12-month mortality of 10%. In this selected cohort of octogenarians, surgery resulted in acceptable short- to medium-term outcomes.The Australasian guidelines recommend use of the CHA2 DS2 -VA schema to stratify ischaemic stroke risk in patients with non-valvular atrial fibrillation (N-VAF) and determine risk thresholds for recommending oral anticoagulant (OAC) therapy. However, the CHA2 DS2 -VA score has not been validated in a representative Australian population cohort with N-VAF, including in Aboriginal people who are known to have a higher age-adjusted stroke risk than other Australians. In a retrospective data-linkage study of 49 114 patients aged 24-84 years with N-VAF, 40.0% women and 2.5% Aboriginal, we found that patients with a CHA2 DS2 -VA score >2 had high annual stroke rates (>2%) that would justify OAC therapy. This occurred regardless of Aboriginal status. Non-Aboriginal patients with a CHA2 DS2 -VA score of 0 had a mean annual stroke rate of 0.4%, and hence were not likely to benefit from antithrombotic therapy. However, Aboriginal patients with a zero CHA2 DS2 -VA score had a significantly higher annual stroke rate of 0.9%, and could potentially obtain net clinical benefit from anticoagulation, primarily with the safer non-vitamin K antagonist OAC. We conclude that clinicians can confidently use the CHA2 DS2 -VA score to make decisions regarding anticoagulation in accordance with stroke risk in patients with N-VAF, except in Aboriginal people in whom the risk score was unable to identify those at truly low risk of stroke.

To allow better allocation of staff and resources, rapid response teams attending to acutely deteriorating or aggressive patients with suspected or confirmed COVID-19 infection were pre-warned with the announcement of 'Code-95' with calls.

To assess healthcare worker (HCW) perspectives on pre-warning rapid response calls (RRC) with 'Code-95' in announcements when attending to deteriorating or aggressive patients with suspected/confirmed COVID-19 infection.

Design prospective cross-sectional single-centre survey of HCW over a 3-week period.

HCW caring for deteriorating or aggressive patients.

the primary outcome was to assess HCW perspectives in attending Code-95 calls. Secondary outcomes were to identify any differences related to craft group, age, experience or presence of comorbidities.

A total of 297 responses was analysed; 86.7% of HCW (n = 257) attending Code-95 calls reported anxiety. Medical staff reported greater anxiety in comparison to nursing staff (93.8% vs 78.
