Studies have reported that miR-195-5p plays a role in the Hirschsprung disease (HSCR). Our previous work found GDNF family receptor alpha 4 (GFRA4) is also associated with HSCR. In this study, we focused on whether miR-195-5p induces the absence of enteric neurons and enteric neural crest in HSCR by regulating GFRA4. The expression levels of GFRA4 and miR-195-5p in colon tissues were evaluated by real-time PCR (RT-PCR) assay. We overexpressed GFRA4 or miR-195-5p in SH-SY5Y cells, the cell proliferation, cell cycle, apoptosis and invasion were subsequently investigated by CCK-8 assay, EdU staining, Flow cytometry analysis and Transwell assay, respectively. We also established the xenograft model to detect the effect of miR-195-5p on tumor growth and GFRA4 and p-RET expressions. GFRA4 expression was significantly downregulated in the HSCR colon tissues when compared with that in the control tissues. Overexpression of GFRA4 significantly promoted proliferation, invasion and cell cycle arrest, and inhibited apoptosis of SH-SY5Y cells. We also proved that GFRA4 is a direct target of miR-195-5p, and miR-195-5p inhibited proliferation, invasion, cell cycle arrest and differentiation, and accelerated apoptosis in SH-SY5Y cells which can be reversed by GFRA4 overexpression. Furthermore, we demonstrated that miR-195-5p suppressed tumor growth, and observably decreased GFRA4 and p-RET expressions. Our findings suggest that miR-195-5p plays an important role in the pathogenesis of HSCR. MiR-195-5p inhibited proliferation, invasion and cell cycle arrest, and accelerated apoptosis of nerve cells by targeting GFRA4.Breast cancer is a highly heterogeneous group of human cancer with distinct genetic, biological and clinicopathological features. Triple-negative breast cancer (TNBC) is the most aggressive and metastatic type of breast cancer and associated with poor patient survival. However, the role of UV Radiation Resistance-Associated Gene (UVRAG) in TNBC remains unknown. Here, we report that UVRAG is highly upregulated in all TNBC cells and its knockdown leads to the inhibition of cell proliferation, colony formation and progression of cell cycle, which is associated with and reduced expression of cell cycle related protein expression, including Cyclin A2, B1, D1, cdc2 and cdk6 in TNBC cells. Inhibition of UVRAG also suppressed cell motility, migration and invasion of TNBC cells by inhibition of Integrin β1 and β3 and Src activity. Our findings suggest for the first time that UVRAG expression contributes to proliferation, cell cycle progression, motility/migration and invasion of TNBC cells. Thus, targeting UVRAG could be a potential strategy in breast cancer especially against TNBC.
Melioidosis is a potentially fatal tropical infection caused by Burkholderia pseudomallei. Kidney involvement is possible, buthas not been well described.

This study aimed to assess the risk of acute kidney injury (AKI) and its outcomes in melioidosis.

A retrospective observational cohort study was performed. Case records of consecutive patients with culture-confirmed melioidosis, observed from January 1st, 2012 through December 31st, 2019 were analysed for demographics, presence of comorbidities, including chronic kidney disease (CKD), diabetes mellitus (DM), and presence of bacteraemia, sepsis, shock, AKI, and urinary abnormalities. The outcomes we studied were mortality, need for hospitalisation in an intensive care unit (ICU), duration of hospitalization. We then compared the outcomes between patients with and without AKI.

Of 164 patients, AKI was observed in 59 (35.98%), and haemodialysis was required in eight (13.56%). In the univariate analysis, AKI was associated with CKD (OR 5.83; CI 1.140-29requent in melioidosis and occurred in 35.9% of our cases. Hyponatremia is likewise common. AKI was predicted by bacteraemia and CKD, and was associated with higher mortality and need for ICU care; however kidney function recovery was observed in survivors.
The pandemic of coronavirus disease (COVID-19) has highlyaffected patients with comorbidities and frailty who cannot self-isolate, such as individuals undergoing haemodialysis. The aim of the study was to identify risk factors for mortality and hospitalisation, which may be useful in future disease spikes.

We collected data retrospectively from the electronic medical records of all patients receiving a diagnosis of COVID-19 between 11th March and 10th May 2020 undergoing maintenance haemodialysis at four satellite dialysis units from the Royal Free London NHS Foundation Trust, London, UK. Mortality was the primary outcome, and the need for hospitalization was the secondary one.

Out of 746 patients undergoing regular haemodialysis, 148 symptomatic patients tested positive for SARS-CoV-2 by RT-PCR and were included in the analysis. The overall mortality rate was 24.3%.

The haemodialysis (HD) dose, as expressed by Kt/V urea, is currently routinelyestimated with the second generation Daugirdas (D2) equation (Daugirdas in J Am Soc Nephrol 41205-1213, 1993). This equation, initially devised for a thrice-weekly schedule, was modified to be used for all dialysisschedules (Daugirdas et al. in Nephrol Dial Transplant 282156-2160, 2013), by adopting a variable factor that adjusts for the urea generation (GFAC) over the preceding inter-dialysis interval (PIDI, days). This factorwas set at 0.008 for the mid-week session of the standard thrice-weekly HD schedule. In theory, by setting PIDI = 7, one could get GFAC = 0.0025, to be used in patients on the once-weekly (1HD/wk) schedule, but actually this has never been tested. Moreover, GFAC was derived not taking into account the residual kidney urea clearance (Kru). Aim of the present study was to provide a specific value of GFAC for patients on aonce-weeklyhemodialysis schedule.

The equation to predict GFAC (GFAC-1) in the 1HD/wk sc linear relationship was found between GFAC and Kru/V in patients on the 1HD/wk schedule. Such a relationship is able to improve the "second generation Daugirdas equation" for an accurate estimate of the single pool Kt/V in this setting. However, a simple replacement in the D2 equation of 0.008 with the mean observed GFAC (0.0035) could suffice in the clinical practice.
