Propoxur is a carbamate insecticide widely used both in indoor and outdoor place to control insects. This present work was conducted to study the effect of exposure of propoxur (PPX) on hormonal and histological changes in the rat testes.

The control animals received distil water, while the treated animals received Propoxur (PPx) by inhalation every other day for one month (PPx-1) and two months (PPx-2) respectively. The animals were euthanized by cervical dislocation; blood sample was obtained for reproductive hormonal assay and the testes were excised following abdominal incision fixed in Bouin's fluid for histological observations.

Significant decrease in the level of testosterone (TT) and increase in follicular stimulating hormone (FSH) and lutenizing hormone (LH) were observed in PPX treated groups alongside with the degenerative changes in the seminiferous tubules, complete loss of spermatogonia population, and the testicular basal membrane. There was no reversal of destruction 30 days after withdrawal of the insecticide, indicating a persistent effect.

The exposure to PPX insecticide has obvious deleterious effects on rat testicular micro-structure and reproductive hormones, Therefore, inhalation of such insecticide should be limited with special care in handling to limit or minimize its hazards.

Edasalonexent (CAT-1004) is an orally-administered novel small molecule that covalently links two bioactive compounds (salicylic acid and docosahexaenoic acid) that inhibit NF-κB. This placebo-controlled, proof-of-concept phase 2 study with open-label extension in boys ≥4- less then 8 years old with any dystrophin mutation examined the effect of edasalonexent (67 or 100 mg/kg/day) compared to placebo or off-treatment control. Endpoints were safety/tolerability, change from baseline in MRI T2 relaxation time of lower leg muscles and functional assessment, as well as pharmacodynamics and biomarkers. Treatment was well-tolerated and the majority of adverse events were mild, and most commonly of the gastrointestinal system (primarily diarrhea). ZK-62711 There were no serious adverse events in the edasalonexent groups. Edasalonexent 100 mg/kg was associated with slowing of disease progression and preservation of muscle function compared to an off-treatment control period, with decrease in levels of NF-κB-regulated genes and improvements in biomarkers of muscle health and inflammation. These results support investigating edasalonexent in future trials and have informed the design of the edasalonexent phase 3 clinical trial in boys with Duchenne.The renin angiotensin aldosterone system (RAAS) is associated with renal disease and inflammation in a diabetes setting, however, little is known about the implicated mechanisms in individuals with long standing diabetes. Accordingly, our aim was to perform an observational study to quantify urinary excretion of inflammatory biomarkers in participants with long standing type 1 diabetes (T1D) (with and without diabetic kidney disease [DKD]) and controls, at baseline and in response to RAAS activation. GFRINULIN, ERPFPAH, and 42 urine inflammatory biomarkers were measured in 74 participants with T1D for ≥50 years (21 with DKD and 44 without DKD [DKD resistors]) and 73 healthy controls. Additionally, inflammatory biomarkers were measured before and after an angiotensin II infusion (ANGII, 1 ng∙kg-1∙min-1). Significantly lower urinary excretion of cytokines (IL-18, IL-1RA, IL-8), chemokines (MCP1, RANTES) and growth factors (TGF-α, PDGFAA, PDGFBB, VEGF-A) was observed in participants with T1D at baseline compared to controls. Urinary IL-6 was higher in DKD than in DKD resistors in an exploratory analysis unadjusted for multiple comparisons. In T1D only, lower GFRINULIN correlated with greater excretion of proinflammatory biomarkers (IL-18, IP-10, & RANTES), growth factors (PDGF-AA & VEGFAA), and chemokines (eotaxin & MCP-1). ANGII increased 31 of 42 inflammatory biomarkers in T1D vs controls (p  less then  0.05), regardless of DKD resistor status. In conclusion, lower GFR and intra-renal RAAS activation were associated with increased inflammation even after longstanding T1D. The increased urinary IL-6 in patients with DKD requires further investigation to determine whether IL-6 is a candidate protective biomarker for prognostication or targeted therapy in DKD.

The novel coronavirus disease 2019 (COVID-19) is a recent viral outbreak that has rapidly spread to multiple countries worldwide. Little is known about COVID-19 infection-related complications.

We report a patient who developed spontaneous bilateral pneumothorax after a recent COVID-19 infection. To our knowledge, this is the first reported case of spontaneous bilateral pneumothorax in a patient with recent confirmed severe acute respiratory syndrome coronavirus-2 infection without any risk factors for pneumothorax and who had not received positive pressure ventilation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? There may be a possible correlation between a recent COVID-19 infection and the development of spontaneous pneumothorax. The diagnosis of spontaneous pneumothorax should be considered in any patient with known or suspected recent COVID-19 infection who presents with new acute symptoms consistent with pneumothorax or sudden clinical deterioration.
