The lack of public awareness of the implication of animal bites and the immediate management in rabies-endemic regions are factors contributing to high rabies mortality.
Pakistan is one of the endemic regions for typhoid fever and paratyphoid fever. This study aimed to identify the evolving antimicrobial sensitivity patterns of Salmonella species causing enteric fever and its implications on the clinical prescribing of antimicrobials.
This was a retrospective descriptive study conducted at a university hospital. Antimicrobial resistance was defined in terms of non-resistant, multidrug resistant (MDR) and extended drug resistant (XDR) as per WHO guidance. Data were collected from the years 2009 and 2019. Chi squared was applied to test for statistical significance (p < 0.05).
A total of 200 patients (100 from 2009 and 100 from 2019) were included in the study. Non-resistant enteric fever cases reduced from 100% in 2009 to 44% in 2019, whereas the MDR and XDR enteric fever cases increased to 16% and 40%, respectively (p < 0.05). Cross tabulation carried out for individual drugs showed an independent rise in the sensitivities of individual first-line antimicrobials.
Antimicrobial resistant enteric fever has become a big challenge for Pakistan. The choice of antibiotic prescription has narrowed down to broader spectrum antimicrobials making it difficult to treat, leading to increased morbidity and mortality.

The pleural vent (PV) is a new drain and valve device enabling ambulatory pneumothorax management. This study analysed the characteristics and outcomes of patients with pneumothorax treated with a PV.
The characteristics and outcomes of 49 patients with pneumothorax treated with a PV between 1 March 2018 and 1 February 2021 were retrospectively analysed.
The mean number of days the PV remained in situ for all patients was 5.6 days, range 0-25, IQR 3-7. Forty patients were managed completely in the ambulatory setting. The total number of days with the PVs in situ was 248. Approximate inpatient bed days saved are 240-320 days. Complications requiring a change in management occurred in nine (18.3%) cases.
This single-centre study shows that ambulatory pneumothorax management with the PV is feasible and associated with inpatient bed savings. Complication rates are less than previously described.

This protease activates the Spike protein of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and of other coronaviruses and is essential for viral spread in the lung. Utilizing rational structure-based drug design (SBDD) coupled to substrate specificity screening of TMPRSS2, we have discovered a novel class of small molecule ketobenzothiazole TMPRSS2 inhibitors with significantly improved activity over existing irreversible inhibitors Camostat and Nafamostat. Lead compound MM3122 ( 4 ) has an IC 50 of 340 pM against recombinant full-length TMPRSS2 protein, an EC 50 of 430 pM in blocking host cell entry into Calu-3 human lung epithelial cells of a newly developed VSV SARS-CoV-2 chimeric virus, and an EC 50 of 74 nM in inhibiting cytopathic effects induced by SARS-CoV-2 virus in Calu-3 cells. Selleckchem AMG-193 Further, MM3122 blocks Middle East Respiratory Syndrome Coronavirus (MERS-CoV) cell entry with an EC 50 of 870 pM. MM3122 has excellent metabolic stability, safety, and pharmacokinetics in mice with a half-life of 8.6 hours in plasma and 7.5 h in lung tissue, making it suitable for in vivo efficacy evaluation and a promising drug candidate for COVID-19 treatment.Tumour evolution is a complex interplay between the acquisition of somatic (epi)genomic changes in tumour cells and the phenotypic consequences they cause, all in the context of a changing microenvironment. Single-cell sequencing offers a window into this dynamic process at the ultimate resolution of individual cells. In this review, we discuss the transformative insight offered by single-cell sequencing technologies for understanding tumour evolution.Renal dysfunction occurs frequently in hospitalized patients with advanced chronic liver disease (ACLD)/cirrhosis and has profound prognostic implications. In ACLD patients with ascites, hepatorenal syndrome (HRS) may result from circulatory dysfunction that leads to reduced kidney perfusion and glomerular filtration rate (in the absence of structural kidney damage). The traditional subclassification of HRS has recently been replaced by acute kidney injury (AKI) type of HRS (HRS-AKI) and non-AKI type of HRS (HRS-NAKI), replacing the terms "HRS type 1" and "HRS type 2", respectively. Importantly, the concept of absolute serum creatinine (sCr) cutoffs for diagnosing HRS was partly abandoned and short term sCr dynamics now may suffice for AKI diagnosis, which facilitates early treatment initiation that may prevent the progression to HRS-AKI or increase the chances of AKI/HRS-AKI reversal. Recent randomized controlled trials have established (a) the efficacy of (long-term) albumin in the prevention of complications of ascites (including HRS-AKI), (b) the benefits of transjugular intrahepatic portosystemic shunt placement in patients with recurrent ascites, and (c) the superiority of terlipressin over noradrenaline for the treatment of HRS-AKI in the context of acute-on-chronic liver failure. This review article aims to summarize recent advances in the understanding and management of HRS.We review the molecular basis of three related basic helix-loop-helix (bHLH) genes (Neurog1, Neurod1, and Atoh1) and upstream regulators Eya1/Six1, Sox2, Pax2, Gata3, Fgfr2b, Foxg1, and Lmx1a/b during the development of spiral ganglia, cochlear nuclei, and cochlear hair cells. Neuronal development requires early expression of Neurog1, followed by its downstream target Neurod1, which downregulates Atoh1 expression. In contrast, hair cells and cochlear nuclei critically depend on Atoh1 and require Neurod1 and Neurog1 expression for various aspects of development. Several experiments show a partial uncoupling of Atoh1/Neurod1 (spiral ganglia and cochlea) and Atoh1/Neurog1/Neurod1 (cochlear nuclei). In this review, we integrate the cellular and molecular mechanisms that regulate the development of auditory system and provide novel insights into the restoration of hearing loss, beyond the limited generation of lost sensory neurons and hair cells.
