An outbreak of a novel coronavirus (COVID-19 or 2019-CoV) infection has posed significant threats to international health and the economy. Patients with COVID-19 are at risk of cytokine storm, acute respiratory distress syndrome (ARDS), reduced blood oxygenation, mechanical ventilation, and a high death rate. Although recent studies have shown remdesivir and dexamethasone as treatment options, there is an urgent need to find a treatment to inhibit virus replication and to control the progression of the disease. Essential biometal zinc has generated a lot of excitement as one of the promising candidates to reduce the severity of COVID-19 infection. Several published observations outlined in the review are the reasons why there is a global enthusiasm that zinc therapy could be a possible therapeutic option. selleck compound However, the biggest challenge in realising the therapeutic value of zinc is lack of optimal treatment modalities such as dose, duration of zinc supplementation and the mode of delivery. In this review, we discuss the regulatory mechanism that hinges upon the bioavailability of zinc. Finally, we propose that intravenous zinc could circumvent the confounding factors affecting the bioavailability of zinc and allow zinc to achieve its therapeutic potential. If successful, due to advantages such as lack of toxicity, low cost and ease of availability, intravenous zinc could be rapidly implemented clinically.
Currently, there is no consensus regarding the timing of delivery in women with non-severe preeclampsia at the late preterm period. The aim of the present meta-analysis is to compare expectant management with immediate delivery in pregnant women with preeclampsia between 34+0 and 36+6 gestational weeks, in terms of maternal and neonatal outcomes.

A search was conducted until October 1, 2020 and eligible studies were identified in MEDLINE, Scopus, Cochrane Central Register of Controlled Trials (Central), the US Registry of clinical trials (www.clinicaltrials.gov), and sources of gray literature without limitations concerning the publication dates and languages. Randomized controlled trials, comparing planned delivery versus expectant management in women with preeclampsia at 34-37weeks were included. The primary outcomes were neonatal intensive care unit (NICU) admission and progression to eclampsia. Secondary outcomes were HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome, severe pCI 0.73-7.25).

Immediate delivery of women with non-severe preeclampsia at the period of late prematurity decreases the risk of a composite adverse maternal outcome by 14%, at the cost of an increase in NICU admissions by 23%. The overall quality of the evidence for these outcomes is high, indicating a high degree of certainty for the results.

Ginsenoside Rg3 and glimepiride have been applied to treat type 2 diabetes (T2DM) because of their good hypoglycemic effects. In this study, the effects of ginsenoside Rg3 acting synergistically with glimepiride were investigated in liver microsomes from rats with type 2 diabetes.

An in vitro incubation system with normal rat liver microsomes (RLM) and type 2 diabetic rat liver microsomes (TRLM) was developed. The system also included two experimental groups consisting of RLM and TRLM pretreated with ginsenoside Rg3 and glimepiride (named the RLMR and TRLMR groups, respectively). The metabolism in the different groups was analyzed by ultra-performance liquid chromatography coupled with quadrupole-orbitrap mass spectrometry (UPLC/Q-Orbitrap MS).

The results showed that the concentration of glimepiride increased in RLM and TRLM after treatment with ginsenoside Rg3. Five metabolites (M1-M5) of glimepiride were found, and they were named 3N-hydroxyglimepiride, hydroxyglimepiride, 1,2-epoxy ether-3-hydroxyglimepiride, 1N-hydroxyglimepiride and 1N,2C,S,O,O-epoxy ether-3-hydroxyglimepiride. The metabolite of ginsenoside Rg3 was ginsenoside Rh2.

An in vitro incubation system with RLM and TRLM was developed. The system revealed pathways that produce glimepiride metabolites. Ginsenoside Rg3 may inhibit the activity of cytochrome P450 enzymes in vitro. The present study showed that ginsenoside Rg3 and glimepiride may be combined for the treatment of T2DM.

Of 3992 deceased donor KT performed in 2014-2015, the incidence of DGF was 54%, ranging from 29.9% to 87.7% among centers. Risk factors (lower-bound-95%CI OR upper-bound-95%CI ) were male gender (1.066 1.2491.463 ), diabetic kidney disease (1.053 1.2961.595 ), time on dialysis (1.005 1.0071.009 ), retransplantation (1.035 1.3971.885 ), preformed anti-HLA antibodies (1.011 1.3831.892 ), HLA mismatches (1.006 1.0661.130 ), donor age (1.011 1.0171.023 ), donor final serum creatinine (sCr) (1.239 1.3171.399 ), cold ischemia time (CIT) (1.031 1.0431.056 ), machine perfusion (0.401 0.5420.733 ), and induction therapy with rabbit antithymocyte globulin (rATG) (0.658 0.8000.973 ). Duration of DGF > 4 days was associated with inferior renal function and DGF > 14 days with the higher incidences of acute rejection, graft loss, and death. In conclusion, the incidence and duration of DGF were high and associated with inferior graft outcomes. While late referral and poor donor maintenance account for the high overall incidence of DGF, variability in donor and recipient selection, organ preservation method, and type of induction agent may account for the wide variation observed among transplant centers.
