This is the first time that a prevention measure of SARS-CoV-2, beyond the use of masks, has proved effective.Introduction Gaucher disease (GD), although pan-ethnic and rare (common in Ashkenazi Jews), is of great importance to hematologists both for diagnosis and management. The need for increased awareness of GD is that delayed diagnosis may lead to preventable irreversible complications (mainly skeletal) or unnecessary invasive procedures (e.g. bone marrow biopsy), and the birth of another affected sibling due to lack of genetic consulting.Areas covered The review outlines the common hematological manifestations of GD, including splenomegaly, thrombocytopenia, and anemia. Other hematological manifestations such as coagulation abnormalities, platelet dysfunction, gammopathy, and other hematological malignancies associated with GD are also discussed. Current and future treatment modalities are delineated, including enzyme replacement and substrate reduction therapy, pharmacological chaperon, and gene therapy. A literature search was conducted to identify original research articles relevant to hematology manifestations and GD published before November 2020.Expert opinion Patients with GD should be ideally followed and treated in a center of excellence where the GD expert benefits from experienced consultants in relevant disciplines. Due to the availability of several very expensive treatment options, it is important to have an unbiased expert who can select the most suitable management for the individual patients (including withholding prescription in asymptomatic patients).Purpose To evaluate the effect of aqueous flare intensity as a measurement of inflammation and microvascular changes on retinal neurodegeneration in diabetic eyes.Materials and Methods In cross-sectional study diabetic patients were assigned into 2 groups according to the presence of retinopathy patients with nonproliferative diabetic retinopathy (group 1) and diabetic patients without clinically overt retinopathy (group 2). As a control group (group 3), age-matched healthy controls were included in the study. All subjects underwent visual acuity measurement, slit-lamp examination, ophthalmoscopy, spectral-domain optic coherence tomography (SD-OCT), optic coherence tomography angiography (OCTA), and laser flare-cell meter (LFCM).Results The study enrolled 99 eyes of 99 patients in group 1; 99 eyes of 99 patients in group 2, and 50 eyes of 50 age-matched healthy controls in group 3. The eyes in group 1 had higher flare intensity, decreased ganglion cell layer (GCL) thickness, enlarged foveal avascular zone (FAZ) area, and enlarged capillary non-flow area compared to those in group 2 (p less then .005). In group 1, decreased GCL thickness was statistically significantly correlated with increased aqueous flare intensity, enlarged FAZ area, and enlarged capillary non-flow area (p less then .005).Conclusion The results demonstrated a correlation of the retinal neurodegeneration with the aqueous flare levels and macular ischemia indices in the early stages of diabetic retinopathy. This finding supports the role of inflammation in the pathogenesis of diabetic retinal neuropathy.

Following percutaneous exposure to the nerve agent VX, the remaining intact agent within the skin after decontamination is of great concern. Consequently, this leads to prolonged agent release to the blood circulation resulting in sustained intoxication, which may complicate the medical management. The decontamination procedure used should therefore possess the ability for agent removal both on and within the skin. The efficacy of three decontamination procedures was evaluated by measuring VX and the primary degradation product ethyl methyl phosphonic acid (EMPA) penetrated through human skin and the amount remaining within the skin.

Decontamination was initiated 5 min post-exposure to VX on human dermatomed skin. Experiments were conducted using an

skin penetration model and the amount remaining within the skin was determined by combining the tape-stripping technique and acetylcholinesterase activity measurements.

In control experiments without decontamination, higher amounts of VX were recovered indation properties are important. In addition, the "wash-in" effect by using soapy water may enhance VX release to the blood circulation.Six months of supplementation with a multi-ingredient nutrition supplement was investigated in older adults with low skeletal muscle mass given the recently purported benefits of such approaches. Community-dwelling older adults (age, 74.9 ± 3.6 y; M/F, 18/19) participated in a double-blind, placebo-controlled, randomized trial involving daily consumption of either fruit juice placebo (PLA) or supplement (SUPP) in the form of a 200-mL carton of a juice-based emulsion of long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA) (3000 mg as 1500 mg docosahexaenoic acid and 1500 mg eicosapentaenoic acid), whey protein isolate (8 g), vitamin D3 (400 IU), and resveratrol (150 mg). Body composition, physical function, and circulating markers of metabolic health were assessed at baseline (PRE), and after 3 (MID) and 6 (POST) months of supplementation. Lean body mass (LBM) was unchanged in either group, but fat mass increased in SUPP by 1.41 (0.75, 2.07) kg at POST (+6.4%; p  less then  .001; d = 0.20). Hand-grip strength was maintained in SUPP, but declined in PLA by 2.50 (0.81, 4.19) kg at POST (-6.8%; p = .002; d = 0.38). Short physical performance battery score was unchanged in PLA, but increased in SUPP by 1.13 (0.41, 1.84) above PRE at POST (p = .001; d = 0.47). Circulating markers of metabolic health were unchanged in response to the intervention in either PLA or SUPP. Long-term supplementation with an LC n-3 PUFA-rich multi-ingredient nutrition supplement demonstrates potential efficacy for improving physical function in older adults in the absence of exercise training and independent of a change in LBM.

The lungs possess many xenobiotic metabolizing enzymes which influence the pharmacokinetics and safety of inhaled medicines. Anticipating metabolism in the lungs provides an opportunity to optimize new inhaled medicines and overcome challenges in their development.

This article summarizes current knowledge on xenobiotic metabolizing enzymes in the lungs. The impact of metabolism on inhaled medicines is considered with examples of how this impacts small molecules, biologics and macromolecular formulation excipients. Methods for measuring and predicting xenobiotic lung metabolism are critically reviewed and the potential for metabolism to influence inhalation toxicology is acknowledged.

Drugs can be optimized by molecular modification to (i) reduce systemic exposure using a 'soft drug' approach, (ii) improve bioavailability by resisting metabolism, or (iii) use a prodrug approach to overcome pharmacokinetic limitations. https://www.selleckchem.com/ Drugs that are very labile in the lungs may require a protective formulation. Some drug carriers being investigated for PK-modification rely on lung enzymes to trigger drug release or biodegrade.
