Exposure to air pollutants is a significant health risk for individuals with asthma, cardiovascular disease, and chronic obstructive pulmonary disease. Measures such as limiting time outdoors or performing less strenuous tasks when air quality levels are better can mitigate these risks, but only if people are aware of both these recommendations and how to know when air quality is best, and worst. Formative audience assessment determined that applications developed for mobile devices are the optimal way to provide this information, but knowledge of the existing United States Environmental Protection Agency (EPA) and partners' AirNow tool was minimal. this website We developed, field-tested, adapted, and implemented pilot efforts at both the national and local levels to address this knowledge gap, and present findings suggesting a concentrated local effort can heighten use of AirNow, leading to more pro-healthy behavior.

Longitudinal Integrated Clerkships (LICs) are a recognised model of curriculum design used internationally as an alternative to traditional block rotations in medical schools that have been shown to offer a multitude of educational benefits. As a relatively new development in the United Kingdom (UK), it is not yet clear whether these benefits will translate into a UK healthcare context. This article provides an early review of evaluations of UK LIC programmes.

A narrative literature review of LIC programme evaluations in UK medical schools.

UK students and faculty found value in the LIC programmes with reported benefits including continuity of relationships, increased responsibility and purpose for students, a patient-centred approach and development of professional skills. However, students and GP tutors expressed initial anxieties adapting to the newness of the programme design and preparedness for exams.

UK LIC programmes appear to be offering benefits for UK medical students and faculty members including personal and professional development in line with international literature. However, the current data is limited with significant gaps that need addressing for the impacts to be fully realised.

PEA POD™ air displacement plethysmography quickly and noninvasively estimates neonatal body fat percentage (BF%). Low PEA POD™ BF% predicts morbidity better than classification as small-for-gestational-age (SGA; <10th centile), but PEA PODs are not widely available. We examined whether skinfold measurements could effectively identify neonates at risk; comparing skinfold BF%, PEA POD™ BF% and birthweight centiles' prediction of hypothermia - a marker of reduced in utero nutrition.

Neonates had customized birthweight centiles calculated, and BF% prospectively estimated by (i) triceps and subscapular skinfolds using sex-specific equations; and (ii) PEA POD™. Medical record review identified hypothermic (<36.5 °C) episodes.

42/149 (28%) neonates had hypothermia. Skinfold BF%, with an area under the curve (AUC) of 0.66, predicted hypothermia as well as PEA POD™ BF% (AUC = 0.62) and birthweight centile (AUC = 0.61). Birthweight <10

centile demonstrated 11.9% sensitivity, 38.5% positive predictive value (PPV) and 92.5% specificity for hypothermia. At equal specificity, skinfold and PEA POD™ BF% more than doubled sensitivity (26.2%) and PPV increased to 57.9%.

Neonatal BF% performs better to predict neonatal hypothermia than birthweight centile, and may be a better measure of true fetal growth restriction. Estimation of neonatal BF% by skinfold measurements is an inexpensive alternative to PEA POD™.

SARS-CoV-2 is highly transmissible and the cause of coronavirus disease 2019 in humans. A wide range of animal species have also been shown to be susceptible to SARS-CoV-2 by experimental and/or natural infections. Sheep are a commonly farmed domestic ruminant that have not been thoroughly investigated for their susceptibility to SARS-CoV-2. Therefore, we performed in vitro and in vivo studies which consisted of infection of ruminant-derived cells and experimental challenge of sheep to investigate their susceptibility to SARS-CoV-2. Our results showed that sheep-derived kidney cells support SARS-CoV-2 replication. Furthermore, the experimental challenge of sheep demonstrated limited infection with viral RNA shed in nasal and oral swabs at 1 and 3-days post challenge (DPC); viral RNA was also detected in the respiratory tract and lymphoid tissues at 4 and 8 DPC. Sero-reactivity was observed in some of the principal infected sheep but not the contact sentinels, indicating that transmission to co-mingled naïve sheep was not highly efficient; however, viral RNA was detected in respiratory tract tissues of sentinel animals at 21 DPC. Furthermore, we used a challenge inoculum consisting of a mixture of two SARS-CoV-2 isolates, representatives of the ancestral lineage A and the B.1.1.7-like alpha variant of concern, to study competition of the two virus strains. Our results indicate that sheep show low susceptibility to SARS-CoV-2 infection and that the alpha variant outcompeted the lineage A strain.Levulinic acid (LEV) has been identified as a key building block chemical produced entirely from biomass. Its derivatives can be used to synthesize a variety of value-added chemicals, such as 2-butanone, 2-methyltetrahydrofuran, and so on. LEV has carbonyl and carboxyl functional groups, which makes it flexible, diverse, and unique during drug synthesis. It also reduces the cost of drug synthesis and makes the reaction cleaner and, not the least, has untapped potential in the field of medicine. This article reviews the application of LEV in cancer treatment, medical materials, and other medical fields. Overall, LEV can be used in the following ways (1) Used as a raw material to directly synthesize drugs; (2) Used to synthesize related derivatives, which can be more specifically used in drug synthesis, and derivatives can achieve the corresponding release of drugs, such as paclitaxel (PTX)- LEV, polymer-betulinic acid (BA)-LEV after amidation; (3) It can modify chemical reagents or act as linkers to connect pharmaceutical reagents with carriers to form pharmaceutical intermediates, a pharmaceutical intermediate skeleton, and so on. (4) It can acylate and esterify to form acetylpropionate and levulinyl, the indole, pyridazine, and other medicinally active functional groups can be synthesized by a long chain, which can reduce the cost of drug synthesis and simplify the tedious synthesis steps. (5) To form the protective group of levulinic acid, the hydroxyl or carboxyl position is first protected, and then the protective group is removed after the corresponding reaction, in order to participate in drug synthesis.Distinct parts of Solanum torvum Swartz. (Solanaceae) are popularly used for a variety of therapeutic purposes. This study determined the phytochemical composition of a phenolic fraction of S. torvum leaf aqueous extract and investigated its antioxidant and liver-protective properties. A phenolic compound-enriched fraction, or phenolic fraction (STLAE-PF) of an infusion (STLAE) of S. torvum leaves, was tested in vitro (antagonism of H2O2 in cytotoxicity and DCF assays with HepG2/C3A cells), and in vivo for antioxidant activity and protective effects against acetaminophen (APAP)-induced liver injury in mice. Thirty-eight compounds (flavonoids, esters of hydroxycinnamic acid, and chlorogenic acid isomers) were tentatively identified (high-performance liquid chromatography coupled to high-resolution electrospray mass spectrometry) in the STLAE-PF fraction. In vitro assays in HepG2/C3A cells showed that STLAE-PF and some flavonoids contained in this phenolic fraction, at noncytotoxic levels, antagonized in a concentration-dependent manner the effects of a powerful oxidant agent (H2O2). In C57BL/6 mice, oral administration of STLAE (600 and 1,200 mg/kg bw) or STLAE-PF (300 mg/kg bw) prevented the rise in serum transaminases (ALT and AST), depletion of reduced glutathione (GSH) and elevation of thiobarbituric acid reactive species (TBARs) levels in the liver caused by APAP (600 mg/kg bw, i.p.). The hepatoprotective effects of STLAE-PF (300 mg/kg bw) against APAP-caused liver injury were comparable to those of N-acetyl-cysteine (NAC 300 or 600 mg/kg bw i.p.). These findings indicate that a phenolic fraction of S. torvum leaf extract (STLAE-PF) is a new phytotherapeutic agent potentially useful for preventing/treating liver injury caused by APAP overdosing.

Diabetic retinopathy (DR), as one of the main complications of diabetes, is among the leading causes of blindness and visual impairment worldwide.

Current clinical therapies include photocoagulation, vitrectomy, and anti-vascular endothelial growth factor (VEGF) therapies. Bevacizumab and ranibizumab are two monoclonal antibodies (mAbs) inhibiting angiogenesis. Intravitreal ranibizumab and bevacizumab can decrease the rate of blindness and retinal thickness, and improve visual acuity whether as monotherapy or combined with other treatments. They can increase the efficacy of other treatments and decrease their adverse events. Although administered intravitreally, they also might enter the circulation and cause systemic effects. This study is aimed to review our current knowledge about mAbs, bevacizumab and ranibizumab, in DR including superiorities, challenges, and limitations. Meanwhile, we tried to shed light on new ideas to overcome these limitations. Our latest search was done in April 2021 mainly through PubMed and Google Scholar. Relevant clinical studies were imported.

Future direction includes detection of more therapeutic targets considering other components of DR pathophysiology and shared pathogenesis of DR and neurodegenerative diseases, such as Parkinson<apos;>s disease and Alzheimer<apos;>s disease, the treat-and-extend regimen, and new ways of drug delivery and other routes of ocular drug administration.

The growing burden of diabetes mellitus and recent progress in understanding cardiovascular outcomes for type 2 diabetes (T2D) patients continue to make the disease a priority for healthcare decision-makers around the world. Our objective was to develop a new, product-independent model capable of projecting long-term clinical and cost outcomes for populations with T2D to support health economic evaluation.

Following a systematic literature review to identify longitudinal study data, existing T2D models and risk formulae for T2D populations, a model was developed (the PRIME Type 2 Diabetes Model [PRIME T2D Model]) in line with good practice guidelines to simulate disease progression, diabetes-related complications and mortality. The model runs as a patient-level simulation and is capable of simulating treatment algorithms and risk factor progression, and projecting the cumulative incidence of macrovascular and microvascular complications as well as hypoglycemic events. The PRIME T2D Model can report clinical outcomes, quality-adjusted life expectancy, direct and indirect costs, along with standard measures of cost-effectiveness and is capable of probabilistic sensitivity analysis.
