The prevalence of FM in active duty service members preparing to deploy is similar to that reported for the general population of the U.S., but higher than expected for a predominantly male cohort. Furthermore, the prevalence of FM was significantly higher in service members with comorbid PTSD and highest among those seeking treatment for PTSD. Further investigation is needed to determine the factors linking PTSD and FM.

Lockdown measures during the SARS-CoV-2 pandemic determined radical changes to behavioral and social habits, that were reflected by a reduction in the transmission of respiratory pathogens and in anthropogenic atmospheric emissions.

This ecological study aims to provide a descriptive evaluation on how restrictive measures during the SARS-CoV-2 pandemic impacted Pediatric Emergency Department (PED) referrals for asthma exacerbations, and their potentially associated environmental triggers in Bologna, a densely populated urban area in Northern Italy.

Files of children evaluated for acute asthma during 2015 to 2020 at the PED of Sant'Orsola University Hospital of Bologna were retrospectively reviewed. Historical daily concentration records of particulate (PM

, PM

) and gaseous (NO

, C

H

) air pollutants, and pollen were concurrently evaluated, including specific PM chemical tracers for traffic-related air pollution (TRAP).

In 2020, asthma-related PED referrals decreased compared to referral ratecreased exposure to ambient pollutants and fewer respiratory infections, identified as the most important factor in the literature.

Middle-aged subjects with meniscal tear treated with arthroscopic partial meniscectomy (APM) experience greater progression of damage to joint structures on imaging than subjects treated nonoperatively. It is unclear whether these changes are clinically relevant.

We used data from the MeTeOR (Meniscal Tear in Osteoarthritis Research) Trial of APM vs. physical therapy for subjects ≥ 45 years with knee pain, cartilage damage, and meniscal tear. We assessed whether change in cartilage surface area damage score (and other structural measures) from baseline to 18 months, assessed on MRI with MOAKS (MRI Osteoarthritis Knee Score), was associated with change in KOOS Pain (Knee Injury and Osteoarthritis Outcome Score; 0-100, 100=worst) from 18-60 months.

The primary analysis included 168 subjects with complete MRI data at baseline and 18 months and KOOS data at 18 and 60 months. We did not observe clinically important associations between change in cartilage surface area score between baseline and 18 months and change in pain scores from 18-60 months. Pain scores in the worst tertile for cartilage surface area damage score progression worsened by 0.45 points more than in the best tertile (95% CI -4.45, 5.35). Similarly, we did not observe clinically important associations between changes in bone marrow lesions, osteophytes, or synovitis and subsequent pain.

We did not observe clinically important associations between early changes in cartilage damage and other structural measures and worsening in pain over the subsequent 3.5 years. Further follow-up is required to assess this association over a longer follow-up period.

To explore the impact of COVID-19 on the management and outcomes of acute paediatric mastoiditis across the UK.

National retrospective and prospective audit SETTING 48 UK secondary care ENT departments PARTICIPANTS Consecutive children aged 18 years or under, referred to ENT with a clinical diagnosis of mastoiditis.

Cases were divided into Period 1 (01/11/19-15/03/20) before the UK population were instructed to reduce social contact, and Period 2 (16/03/20-30/04/21), following this. Periods 1&2 were compared for population variables, management and outcomes. Crenolanib mouse Secondary analyses compared outcomes by primary treatment (medical/needle aspiration/surgical).

286 cases met criteria (median 4 per site, range 0-24). 9.4 cases were recorded per week in period 1 versus 2.0 in period 2, with no winter increase in cases in Dec 2020-Feb 2021. Patient age differed between period 1&2 (3.2 Vs 4.7 years respectively, p<0.001). 85% of children in period 2 were tested for COVID-19 with a single positive test. In period 2 cases associated with P. aeruginosa significantly increased. 48.6% of children were scanned in period 1 vs 41.1% in period 2. Surgical management was used more frequently in period 1 (43.0% Vs 24.3%, p=0.001). Treatment success was high, with failure of initial management in 6.3%, and 30-day re-admission for recurrence in 2.1%. The adverse event rate (15.7% overall) did not vary by treatment modality or between periods 1& 2.

All cells have two major forms of DNA topoisomerases type I enzymes, which make single-stranded cuts in DNA, and type II enzymes, which cut and decatenate double-stranded DNA. DNA topoisomerases are important targets of approved and experimental anti-cancer agents. Provided in this article are protocols to assess activities of topoisomerases and their inhibitors. Included are an assay for topoisomerase I activity based on relaxation of supercoiled DNA; an assay for topoisomerase II based on the decatenation of double-stranded DNA; and approaches for enriching and quantifying DNA-protein covalent complexes formed as obligatory intermediates in the reactions of type I and II topoisomerases with DNA; and assays for measuring DNA cleavage in vitro. Topoisomerases are not the only proteins that form covalent adducts with DNA in living cells, and the approaches described here are likelytocol 6 Determination of DNA cleavage by purified topoisomerase I Basic Protocol 7 Determination of inhibitor effects on DNA cleavage by topoisomerase II using a plasmid linearization assay Alternate Protocol Gel electrophoresis determination of topoisomerase II cleavage.

The human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) has long affected millions of individuals across the globe. Historically, the prevalence of this disease is particularly noted within the African continent. Before the coronavirus disease 2019 (COVID-19) pandemic, many African countries struggled to effectively manage the increasing burden associated with HIV/AIDS. There is now a need to reassess this in a COVID-19 pandemic context so that the impact of COVID-19 on HIV/AIDS healthcare within Africa can be adequately evaluated.

Data collection was performed on the PubMed, Ovid MEDLINE and Embase bibliographical databases with a predefined search strategy. Searches were performed in blind duplicate and all articles considering COVID-19 and HIV/AIDS within African healthcare were considered.

The COVID-19 pandemic has severely exacerbated the many issues surrounding HIV/AIDS care within many African countries. These impacts are noticeable in medical, psychological, and socio-political contexts.

Before efforts are made to improve the provision of HIV/AIDS and COVID-19 care within Africa, it is important that this issue is brought to the attention of the scientific and clinical community so that the continent can receive the necessary support and aid.

However, only a few epidemiological studies have reported dairy products as being a risk factor for prostate cancer in Japan, reporting contradictory results. We therefore investigated the association between the intake of dairy products and the occurrence of prostate cancer through a large-scale cohort study. The Japan Collaborative Cohort study analyzed approximately 110,000 residents from various Japanese districts who participated in our questionnaire survey during 1988-1990. The subjects of the present study were 26,464 men (age range 40-79 years) from 24 districts wherein cancer incidence was reported. Their clinical course was followed up until 2009. Hazard ratios (HRs) were calculated using Cox's proportional hazards model, adjusted for age, survey area, family history of prostate cancer, body mass index, and total energy intake. For diet, we calculated the HRs associated with intermediate and high consumption of dairy products and compared them with those associated with low consumption. There were 412 cases of prostate cancer in the survey population. As dairy products, milk, yogurt, cheese, and butter were evaluated. Among them, milk consumption was associated with a significant risk (HR = 1.37, p = 0.009) and a dose-dependent response (p for trend = 0.009) adjusted for age and family history of prostate cancer, stratified by area. Milk and yogurt consumption showed a significantly positive risk and a dose-response relationship adjusted for age, family history of prostate cancer, body mass index, and total energy intake, stratified by area. In summary, a high intake of dairy products such as milk increased the risk of developing prostate cancer in Japanese men.A novel fluorescent probe was designed and synthesized from tetraphenylethene (TPE) and polyhedral oligomeric silsesquioxanes (POSS) via Heck-palladium catalyzed cross-coupling reaction. The as-synthesized TPE functionalized probe performed good solvent stability and selectively preconcentration capability towards target analyte due to its stable structure and the adsorption property. The morphology as well as the physical and chemical properties of the POSS@TPE were carefully characterized. The POSS@TPE was employed to develop an effective fluorescent probe for trifluralin, with a response range of 0.1-80 mg/kg and a detection limit of 0.102 mg/kg. The mixed mechanisms of inner-filter effect (IFE) and photoinduced electron transfer (PET) explain the selectivity of POSS@TPE. Rapid detection for trifluralin in tomato and celery has been achieved with recoveries between 99.4-120.7% (RSD≤3.4%), and the results were verified compared with GC-MS method.It has been a landmark year for artificial intelligence (AI) and biotechnology. Perhaps the most noteworthy of these advances was Google DeepMind's AlphaFold2 algorithm which smashed records in protein structure prediction (Jumper et al., 2021, Nature, 596, 583) complemented by progress made by other research groups around the globe (Baek et al., 2021, Science, 373, 871; Zheng et al., 2021, Proteins). For the first time in history, AI achieved protein structure models rivalling the accuracy of experimentally determined structures. The power of accurate protein structure prediction at our fingertips has countless implications for drug discovery, de novo protein design and fundamental research in chemical biology. While acknowledging the significance of these breakthroughs, this perspective aims to cut through the hype and examine some key limitations using AlphaFold2 as a lens to consider the broader implications of AI for microbial biotechnology for the next 15 years and beyond.
