Assessment of adverse drug reactions to antituberculosis regimen in a tertiary care hospital

Background: Adverse drug reactions are common with multidrug therapy in tuberculosis, if detected early can improve patient compliance and prevent emergence of resistance.Methods: A prospective observational study as a part of Pharmacovigilance Program under Central Drugs Standard Control Organisation was conducted in Kasturba hospital, Manipal to collect adverse drug reactions (ADR). Data of patients reported with antitubercular treatment (ATT) related ADRs from September 2012 to August 2013 was evaluated for patient demography, type of tuberculosis, ATT regimen, organ/ system affected and time of onset of ADR. ADRs were then subjected to causality assessment as per WHO scale.Results: A total of 65 ADRs were reported in 60 patients during the study period, of which 46.7% were in males and 53.3% in females. 85% of ADRs were reported in patients with pulmonary tuberculosis. 77% of ADRs were observed with daily regimen. Common ADRs were hepatitis (40%), gastritis (15%), skin reactions (15%), peripheral neuropathy (14%), gout (6%) and nephritis (3%). Median duration for the onset of ADR was 31 days each for hepatitis, gout, nephritis and 20, 11, 9 days for gastritis, peripheral neuropathy and skin reactions respectively. As per causality assessment, 80% of ADRs were assigned “possible”, 11% “probable” and 9% “certain”. As per severity scale 27.7% of ADR were severe, 36.9% were moderate.Conclusions: Early detection and management of ADRs is vital for the success of ATT and patient adherence

EVALUATION OF DIURETIC AND ANTIUROLITHIATIC PROPERTIES OF ETHANOLIC EXTRACT OF SIDA ACUTA BURM. F. IN WISTAR ALBINO RATS

Objective: To evaluate the diuretic and antiurolithiatic properties of ethanolic extract of Sida acuta Burm. f. in albino rats.Methods: Three different doses of Sida acuta (100 mg/kg, 200 mg/kg, 400 mg/kg) were tested for diuretic activity and compared with furosemide (25 mg/kg) and control group. 24 hr urine output and urinary concentrations of sodium (Na+), potassium (K+) and chloride (Cl-) ions were the parameters measured. Prophylactic and curative antiurolithiatic activity was tested for three doses (100 mg/kg, 200 mg/kg & 400 mg/kg) of Sida acuta and compared with control group and animals treated with standard herbal preparation Cystone (750 mg/kg) using zinc disc implantation model.Results: Sida acuta (400 mg/kg) significantly increased the urine output (p<0.001), which was almost equivalent to furosemide. Sida acuta also caused a significant increase in the excretion of K+ and Cl-at higher doses (200 mg/kg, 400 mg/kg). Effects on Na+excretion were not significant for all three doses of the test drug. Sida acuta (200 mg/kg, 400 mg/kg) showed statistically significant (p<0.05) reduction in depositions around zinc discs as compared to control when tested in prophylactically treated rats, but not in rats treated post-urolithiasis induction.Conclusion: Sida acuta produced a dose-dependent increase in urine output, with no effect on sodium excretion. This probably indicates that the diuresis produced could be due to its aquarectic action. It also showed significant prophylactic antiurolithiatic activity, but further studies are necessary to evaluate fully its therapeutic potential.Keywords: Zinc disc implantation, Calculi, Diuretic index, Cyston

The development and validation of a scoring tool to predict the operative duration of elective laparoscopic cholecystectomy

Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p  90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care

PANC Study (Pancreatitis: A National Cohort Study): national cohort study examining the first 30 days from presentation of acute pancreatitis in the UK

Abstract Background Acute pancreatitis is a common, yet complex, emergency surgical presentation. Multiple guidelines exist and management can vary significantly. The aim of this first UK, multicentre, prospective cohort study was to assess the variation in management of acute pancreatitis to guide resource planning and optimize treatment. Methods All patients aged greater than or equal to 18 years presenting with acute pancreatitis, as per the Atlanta criteria, from March to April 2021 were eligible for inclusion and followed up for 30 days. Anonymized data were uploaded to a secure electronic database in line with local governance approvals. Results A total of 113 hospitals contributed data on 2580 patients, with an equal sex distribution and a mean age of 57 years. The aetiology was gallstones in 50.6 per cent, with idiopathic the next most common (22.4 per cent). In addition to the 7.6 per cent with a diagnosis of chronic pancreatitis, 20.1 per cent of patients had a previous episode of acute pancreatitis. One in 20 patients were classed as having severe pancreatitis, as per the Atlanta criteria. The overall mortality rate was 2.3 per cent at 30 days, but rose to one in three in the severe group. Predictors of death included male sex, increased age, and frailty; previous acute pancreatitis and gallstones as aetiologies were protective. Smoking status and body mass index did not affect death. Conclusion Most patients presenting with acute pancreatitis have a mild, self-limiting disease. Rates of patients with idiopathic pancreatitis are high. Recurrent attacks of pancreatitis are common, but are likely to have reduced risk of death on subsequent admissions. </jats:sec

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

Not AvailableCollagen is one of the most widely used biomaterials in tissue engineering and regenerative medicine. To investigate the effect of fish collagen peptides on the formation of collagen proteins by mature osteoblast cells, human osteoblast cells were treated with collagen peptide in both time and dose dependent manner. The stimulatory effect of collagen peptide was confirmed by western blot and immunocytochemistry analysis. The results clearly indicate that the presence of fish collagen peptides led to a dose dependent increase in collagen synthesis by osteoblast cells upto a concentration of 0.6 mg ml-1. However native collagen or collagen free protein hydrolysate failed to stimulate the production of collagen in osteoblast cells. The results show a stimulatory effect of fish collagen peptides on the collagen biosynthesis in osteoblast cells and suggest a possible mechanism for the regulation of collagen turnover in joint tissues.Not Availabl
