The current global demand for novel anti-TB drugs has drawn urgent attention on the discovery of natural product compounds with anti-TB activity. Lots of efforts have emphasized on environmental samples from unexplored or underexplored natural habits and identified numerous rare actinomycete taxa producing structurally diverse bioactive natural products. Herein, we report a survey of the rare actinobacteria diversity in Xinjiang region together with the discovery of anti-TB active natural products from these strains. We have collected 17 soil samples at different sites with different environmental conditions, from which 39 rare actinobacteria were identified by using a selective isolation strategy with 5 media variations. Among those isolated strains, XJ31 was identified as a new Nocardia sp. based on 16S rRNA gene analysis. Through one strain-many compounds (OSMAC) strategy combined with anti-Bacillus Calmette-Guérin bioassay-guided isolation, two groups of compounds were identified. They were twelve siderophores (nocardimicins, 1-12) and two anthraquinones (brasiliquinones, 13 and 14) and ten of them were identified as new compounds. The structures of the purified compounds were elucidated using HR-ESI-MS, 1D NMR, and 2D NMR techniques. The anti-TB bioassays revealed that the two benz[α]anthraquinones have potent activity against BCG (MICs = 25 μM), which can be used as a promising start point for further anti-TB drug development. KEY POINTS • Ten new natural products were identified from Nocardia sp. XJ31. • Brasiliquinones 13 and 14 showed moderate anti-BCG activity.Plant virus-based expression systems are an alternative expression platform for the production of clinically and industrially useful recombinant proteins. Nonetheless, due to a lack of viral vector with the commercial potentials, it is urgent to design and develop new, versatile, and efficient plant virus vectors. The genome of Tomato bushy stunt virus (TBSV) offers an attractive alternative to being modified as a vector for producing heterologous proteins in plants. Here, we developed a set of novel fusion and non-fusion TBSV-CP replacement vectors, which provide more flexible and efficient tools for expressing proteins of interest in plants. An alternative tobacco plant, Nicotiana excelsiana, was used in this study as a host for newly constructed TBSV vectors because the unwanted necrotic effects were reported on the commonly used Nicotiana benthamiana host associated with expression of TBSV-encoded P19 protein. The data showed that TBSV vectors caused a symptomless infection and overexpressed reporter gene in N. excelsiana leaves, demonstrating that N. excelsiana is an ideal host plant for TBSV-mediated heterologous gene expression. Moreover, a TBSV non-fusion vector, dAUG, shows the similar accumulation level of reporter proteins to that of TMV- and PVX-based vectors in side-by-side comparison and provides more flexible aspects than the previously developed TBSV vectors. Collectively, our newly developed TBSV expression system adds a new member to the family of plant viral expression vectors and meanwhile offers a flexible and highly effective approach for producing proteins of interest in plants. KEY POINTS • The TBSV-based transient expression system has been significantly improved. • The necrotic effects caused by viral P19 protein were avoided by the usage of N. excelsiana as a host plant. • The expression level of the non-fusion vector was similar to the most effective virus vectors reported so far.The aims of the proposed study were to develop and verify a quantitative model-based framework to anticipate the in vivo bioequivalence of ibuprofen immediate release formulations. This stepwise approach integrated virtual bioequivalence trials to simulate the test to reference (T/R) ratio for positive (i.e., bioequivalent) and negative (i.e., non-bioequivalent) control formulations containing ibuprofen, approximated distribution of interoccasion variability (IOV) on ibuprofen peak (Cmax) and extent of exposure (AUC) by bootstrapping resampling methods, post hoc incorporation of IOV to simulated T/R ratios, and power curve analysis. After post hoc incorporation of the bootstrapped IOV to the simulated Cmax T/R geometric mean ratios, the resulting 90% confidence intervals overlapped with the in vivo observations for both pairwise comparisons. On the other hand, simulated and observed AUC TNBE/R geometric mean ratios differed, likely due to the lack of propagating clearance-related IOV to the simulations. This approach is in line with modern regulatory initiatives that advocate leveraging quantitative methods and modeling to modernize generic drug development and review. Graphical abstract.
The role of renin-angiotensin-aldosterone system (RAAS) inhibitors, notably angiotensin-converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARBs), in the COVID-19 pandemic has not been fully evaluated. With an increasing number of COVID-19 cases worldwide, it is imperative to better understand the impact of RAAS inhibitors in hypertensive COVID patients. PubMed, Embase and the pre-print database Medrxiv were searched, and studies with data on patients on ACEi/ARB with COVID-19 were included. Random effects models were used to estimate the pooled mean difference with 95% confidence interval using Open Meta[Analyst] software.

A total of 28,872 patients were included in this meta-analysis. The use of any RAAS inhibition for any conditions showed a trend to lower risk of death/critical events (OR 0.671, CI 0.435 to 1.034, p = 0.071). Within the hypertensive cohort, however, there was a significant lower association with deaths (OR 0.664, CI 0.458 to 0.964, p = 0.031) or the combination of de p = 0.010). There was no significant association of critical/death outcomes within ACEi vs non-ACEi (OR 1.008, CI 0.822 to 1.235, p = 0.941) and ARB vs non-ARB (OR 0.946, CI 0.735 to 1.218, p = 0.668). This is the largest meta-analysis including critical events and mortality data on patients prescribed ACEi/ARB and found evidence of beneficial effects of chronic ACEi/ARB use especially in hypertensive cohort with COVID-19. As such, we would strongly encourage patients to continue with RAAS inhibitor pharmacotherapy during the COVID-19 pandemic.Propolis, which is produced by honeybees and is used in "natural" products, can cause contact allergy. The composition of propolis varies between regions, but little is known about how this variation affects contact allergenicity. The aims of this study were to investigate the frequency of propolis contact allergy in western Sweden, and whether the frequency varies according to the origin of the propolis. Patch-testing was performed using propolis from China, Lithuania, North America, and Sweden in 722 consecutive patients with dermatitis in western Sweden. Frequencies of positive patch-test reactions ranged from 2.4% to 3.6%. GSK744 There were some, not statistically significant, differences in frequency of contact allergy to the 4 samples of propolis of different origins, with the highest frequency to the sample from China and the lowest frequency to the sample from Sweden. Concomitant positive patch-test reactions to plant and fragrance substances in the baseline series were common, most frequently to Myroxylon pereirae resin and colophonium.
COVID-19 is a multisystem illness that has considerable long-term physical, psychological, cognitive, social and vocational sequelae in survivors. Given the scale of this burden and lockdown measures in most countries, there is a need for an integrated rehabilitation pathway using a tele-medicine approach to screen and manage these sequelae in a systematic and efficient way.

A multidisciplinary team of professionals in the UK developed a comprehensive pragmatic telephone screening tool, the COVID-19 Yorkshire Rehabilitation Screen (C19-YRS), and an integrated rehabilitation pathway, which spans the acute hospital trust, community trust and primary care service within the National Health Service (NHS) service model.

The C19-YRS telephone screening tool, developed previously, was used to screen symptoms and grade their severity. Referral criteria thresholds were applied to the output of C19-YRS to inform the decision-making process in the rehabilitation pathway. A dedicated multidisciplinary COVID-19 rehabilitation team is the core troubleshooting forum for managing complex cases with needs spanning multiple domains of the health condition.

The authors recommend that health services dealing with the COVID-19 pandemic adopt a comprehensive telephone screening system and an integrated rehabilitation pathway to manage the large number of survivors in a timely and effective manner and to enable the provision of targeted interventions.

This study elucidated the effects of exercise training on physical activity, 6-min walk distance, and all-cause hospitalization rates in patients with chronic heart failure, and evaluated factors contributing to changes in physical activity.

Prospective cohort observational study.

Patients (n =62) who completed an exercise training programme after implantable cardioverter-defibrillator or cardiac resynchronization therapy treatment between May 2017 and May 2018 were included. Patients exercised for 20-50 min 3-5 times weekly for 3 months and were assigned to the active (≥ 10 min/day) or non-active (< 10 min/day) group based on changes in walking times between baseline and 3 months, as assessed by the International Physical Activity Questionnaire.

The 6-min walk distance improved in both groups with exercise training. Physical activity level did not increase in some patients, despite improvements in exercise tolerance. Depression improved significantly in the active group, but no correlation was found with physical activity. Factors contributing to physical activity changes were not identified. The all-cause hospitalization rate was lower in the active group during follow-up (mean 10.5 months).

Exercise training effectively increased 6-min walk distance regardless of physical activity. Non-active patients experienced increased all-cause hospitalizations. Increasing physical activity improves patient outcomes.

To evaluate the effectiveness of non-surgical interventions for rotator cuff calcific tendinopathy.

Medline, EMBASE, CINAHL, Cochrane Register of Clinical Trials, PEDro and SPORTDiscus from inception to March 2018, and accompanying reference lists. Peer-reviewed randomized clinical trials of non-surgical interventions for adults with rotator cuff calcific tendinopathy were included.

The same 2 reviewers independently evaluated eligibility, extracted data and evaluated risk of bias of the included randomized clinical trials. A system to resolve any disagreements was established a priori. Short-term, medium-term and long-term outcomes for pain, shoulder function and calcific morphology related to rotator cuff calcific tendinopathy were extracted. Due to diversity in outcome measures a meta-analyses was not conducted.

Of the 2,085 articles identified, 18 met the inclusion criteria, all of which had high risk of bias. Five non-surgical interventions were identified (extracorporeal shockwave therapy, ultrasound-guided percutaneous intervention, pulsed ultrasound, acetic acid iontophoresis, and transcutaneous electrical nerve stimulation).
