Rationale & objective Sodium glucose cotransporter 2 (SGLT2) inhibitors slow the progression of chronic kidney disease and prevent heart failure events. However, SGLT2 inhibitors may increase the risk of acute kidney injury (AKI). Our objective was to assess whether SGLT2 inhibitor use, compared to all other glucose lowering drugs (oGLD), is associated with increased rates of AKI. Study design Retrospective cohort study. Setting & participants Adults in Manitoba, Canada with type 2 diabetes mellitus (T2DM) followed from June 2014 until March 2017. Exposures Initial SGLT2 inhibitor or oGLD use ascertained through a province-wide outpatient prescription database. Outcome The primary outcome was incident AKI, identified either by a rise in serum creatinine and/or hospital discharge codes for AKI while taking glucose lowering drugs (on-treatment approach). Analytical approach A propensity score analysis was used to assemble groups of incident users of SGLT2 inhibitors and a 11 matched set of users of oGLD. The rate of AKI was compared across matched groups using cause-specific hazards models. Sensitivity analyses considered exposure to be constant throughout follow-up after initiation of the drug (intention-to-treat approach) or incorporated recurrent exposures (new user design). Results Comparing 4,778 incident users of SGLT2 inhibitor to 4,778 incident users of oGLD, there were no differences observed in the primary outcome (HR 0.64, 95% CI 0.40 - 1.03, p = 0.064) using an on-treatment approach. In neither set of sensitivity analyses were SGLT2 inhibitors associated with an increased risk of AKI. Limitations Drug choice may have been related to AKI risk, laboratory data were obtained from clinical care, and changes in adverse event reporting may have followed the FDA warning. There were insufficient data to compare individual SGLT2 inhibitors. Conclusions Compared to oGLD, SGLT2 inhibitors were not observed to be associated with an increased risk of AKI in a clinical population-based cohort.Background Alzheimer's disease (AD) is the most common cause of dementia in elderly. Quercetin is a well-known flavonoid with low bioavailability. Recently, quercetin nanoparticles (QNPs) has been shown to have a better bioavailability. Aims This study aimed to investigate the protective and therapeutic effects of QNPs in Aluminum chloride (AlCl3) induced animal model of AD. Materials and methods AD was induced in rats by oral administration of AlCl3 (100 mg/kg/day) for 42 days. QNPs (30 mg/kg) was given along with AlCl3 in the prophylactic group and following AD induction in the treated group. Hippocampi were harvested for assessments of the structural and ultrastructural changes using histological and histochemical approaches. Results and discussion AD hippocampi showed a prominent structural and ultrastructural disorders both neuronal and extraneuronal. Including neuronal degeneration, formation of APs and NFTs, downregulation of tyrosine hydroxylase (TH), astrogliosis and inhibition of the proliferative activity (all P ≤ 0.05). Electron microscopy showed signs of neuronal degeneration with microglia and astrocyte activation and disruption of myelination and Blood Brain Barrier (BBB). Interestingly, QNPs administration remarkably reduced the neuronal degenerative changes, APs and NFTs formation (all P ≤ 0.05). Furthermore, it showed signs of regeneration (all P ≤ 0.05) and upregulation of TH. The effect was profound in the prophylactic group. Thus, QNPs reduced the damaging effect of AlCl3 on hippocampal neurons at the molecular, cellular and subcellular levels. https://www.selleckchem.com/products/th-z816.html Conclusion For the best of our knowledge this is the first study to show a prophylactic and therapeutic effect for QNPs in AD model. This might open the gate for further research and provide a new line for therapeutic intervention in AD.Pseudorabies (PR) caused by re-emerging pseudorabies virus (PRV) variant has outbroken among PRV vaccine-immunized swine herds on many Chinese pig farms, with severe socioeconomic consequences since late 2011. Here, a gE/gI/TK-deleted recombinant virus (rPRV NY-gE-/gI-/TK-) was constructed based on PRV NY strain from 2012 through homologous DNA recombination and gene-editing technology termed clustered regularly interspaced palindromic repeats (CRISPR)/associated (Cas9) system. The rPRV NY-gE-/gI-/TK- strain showed similar growth kinetics to the parental PRV NY strain in vitro, and was safe for mice. Sixty mice were injected subcutaneously (s.c.) twice with 106.0 TCID50 of rPRV NY-gE-/gI-/TK- and DMEM, respectively, with two-week interval. The levels of PRV gB antibodies and neutralizing antibodies against PRV NY in mice immunized with rPRV NY-gE-/gI-/TK- were higher than those in the DMEM control group. The number of T lymphocyte subclasses CD3+, CD4+ and CD8+ in rPRV NY-gE-/gI-/TK--immunized mice was higher than that in DMEM-injected mice. After challenge with 106.0 TCID50 PRV NY at 42 dpi, all rPRV NY-gE-/gI-/TK--immunized mice survived without exhibiting any pathological lesions in different tissues and intranuclear eosinophilic inclusions of the brain, and the viral genomic copy numbers in various organs of mice were obviously lower than DMEM group. These results showed the rPRV NY-gE-/gI-/TK- could be a promising next-generation vaccine to control now epidemic PR in China.Self-reported depression has been observed in coronavirus disease-2019 (COVID-19) patients, infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), during discharge from the hospital. However, the cause of this self-reported depression during the convalescent period remains unclear. Here, we report the mental health status of 96 convalescent COVID-19 patients who were surveyed using an online questionnaire at the Shenzhen Samii Medical Center from March 2 to March 12, 2020 in Shenzhen, China. After obtaining their informed consent, we retrospectively analyzed the clinical characteristics of patients, including routine blood and biochemical data. The results suggested that patients with self-reported depression exhibited increased immune response, as indicated by increased white blood cell and neutrophil counts, as well as neutrophil-to-lymphocyte ratio. However, the mechanism linking self-reported depression to these cellular changes needs further study. In conclusion, self-reported depression occurred at an early stage in convalescent COVID-19 patients, and changes in immune function were apparent during short-term follow-up of these patients after discharge.
