RESUMEN

OBJECTIVE: Endoscopic ultrasound(EUS) guided drainage of walled off necrosis(WON) with either plastic stents or metal stents is the mainstay of WON management. This is a single center randomized controlled study evaluating the efficacy of bi-flanged metal stent(BFMS) and plastic stents for WON drainage. DESIGN: Patients with symptomatic WON amenable for EUS guided drainage were randomized to either BFMS or plastic stents. Primary outcome was reintervention free clinical success at 4 weeks. Secondary outcomes were overall clinical success(complete resolution of symptoms and significant reduction in size of WON (<50% of original size and <5 cm largest diameter size at 4-week follow-up)), number of re-interventions, adverse events, hospital stay for first admission and medium term outcomes at 6 months (recurrence, disconnected pancreatic duct, chronic pancreatitis and new onset diabetes mellitus). RESULTS: 92 patients were randomized - 46 in each arm. The reintervention free clinical success was significantly higher in BFMS group(67.4% vs 43.5%; P: 0.021; ITT analysis). Overall clinical success at one month was similar in both groups. There were significantly lower number of reinterventions (median 0(IQR 0-1) vs 1(0-2) P:0.028)and hospital stay duration in BFMS group(7.04 ± 3.36 days vs 9.09 ± 5.53 days; P:0.035). There was no difference in procedure-related adverse events, mortality and medium-term outcomes. CONCLUSIONS: The BFMS provides higher reintervention free clinical success at 4 weeks with shorter hospital stay without increased risk of adverse events compared to plastic stents for EUS-guided drainage of WON. Medium term outcomes are however similar in both BFMS, and plastics stents.

RESUMEN

OBJECTIVES: While dysregulation of DSCC1 (DNA Replication And Sister Chromatid Cohesion 1) has been established in breast cancer and colorectal cancer, its associations with other tumors remain unclear. Therefore, this study was launched to explore the role of DSCC1 in pan-cancer. METHODOLOGY: In this study, we investigate the biological functions of DSCC1 across 33 solid tumors, elucidating its role in promoting oncogenesis and progression in various cancers through comprehensive analysis of multi-omics data. RESULTS: We conducted a comprehensive analysis of DSCC1 expression using RNA-seq data from TCGA and GTEx databases across 30 cancer types. Striking variations were observed, with significant overexpression of DSCC1 identified in numerous cancers. Elevated DSCC1 level was strongly associated with poorer prognosis, shorter survival, and advanced tumor stages in kidney renal papillary cell carcinoma (KIRP), liver hepatocellular carcinoma (LIHC), lung adenocarcinoma (LUAD), as indicated by Kaplan-Meier curves and GEPIA2 analysis. Further investigation into the molecular mechanisms revealed reduced DNA methylation in the DSCC1 promoter region in KIRP, LIHC, and LUAD, supporting enhanced RNA transcription. Protein expression analysis via the Human Protein Atlas (HPA) corroborated mRNA expression findings, showcasing elevated DSCC1 protein in KIRP, LIHC, and LUAD tissues. Mutational analysis using cBioPortal revealed alterations in 0.4% of KIRP, 17% of LIHC, and 5% of LUAD samples, predominantly characterized by amplification. Immune cell infiltration analysis demonstrated robust positive correlations between DSCC1 expression and CD8+ T cells, CD4+ T cells, and B cells, influencing the tumor microenvironment. STRING and gene enrichment analyses unveiled DSCC1's involvement in critical pathways, emphasizing its multifaceted impact. Notably, drug sensitivity analysis highlighted a significant correlation between DSCC1 mRNA expression and responses to 78 anticancer treatments, suggesting its potential as a predictive biomarker and therapeutic target for KIRP, LIHC, and LUAD. Finally, immunohistochemistry staining of clinical samples validated computational results, confirming elevated DSCC1 protein expression. CONCLUSION: Overall, this study provides comprehensive insights into the pivotal role of DSCC1 in KIRP, LIHC, and LUAD initiation, progression, and therapeutic responsiveness, laying the foundation for further investigations and personalized treatment strategies.

RESUMEN

OBJECTIVE: To develop an effective antimicrobial strategy for the management of chronic osteomyelitis. STUDY DESIGN: Observational study. Place and Duration of the Study: Departments of Microbiology and Orthopaedics, Combined Military Hospital Malir, Karachi, Pakistan, from January 2021 to February 2022. METHODOLOGY: Bone biopsies of 45 enrolled participants were taken for microbiological evaluation. Intravenous antibiotic therapy was begun as per empirical therapy based on the local antibiogram and antibiotic policy. Once the susceptibility pattern was available, targeted therapy started and continued for 28 to 42 days. Patients were evaluated based on inflammatory markers and clinical conditions for a minimum of six months to a maximum of one year. RESULTS:  Out of the 45 patients, the majority 29% were soldiers, 40% belonging to the age group of 31-60 years. The common predisposing factor was trauma/fractures followed by diabetes and implants leading to chronic sinus discharge and decubitus ulcers. The most commonly isolated organism was Staphylococcus aureus (38%) followed by Methicillin-resistant Staphylococcus aureus (MRSA) (31%). Cotrimoxazole and Rifampicin turned out to be good treatment options. Only 4.4% showed unsatisfactory prognosis, nonetheless, no mortality was observed during the course of treatment. CONCLUSION: In this study, highly resistant strains were observed with limited treatment options for chronic osteomyelitis, however, effective stewardship programmes with accurate diagnostic reporting and judicious use of antimicrobials can prevent overuse of the valuable resources. KEY WORDS: Antimicrobial stewardship, Osteomyelitis, Methicillin-resistant Staphylococcus aureus, Empirical therapy, Antimicrobial resistance.

RESUMEN

BACKGROUND: Extracorporeal shockwave lithotripsy (ESWL) and/or endoscopic retrograde cholangiopancreatography (ERCP) are recommended as first-line therapy for painful uncomplicated chronic pancreatitis with obstructed main pancreatic duct (MPD) in the pancreas head/body. However, predictors of pain relief after ESWL are unknown. We evaluated independent predictors of persistent pain in patients who underwent ESWL for chronic pancreatitis. METHODS: 640 consecutive adult patients with chronic pancreatitis, who underwent successful ESWL with ERCP and pancreatic duct (PD) stent placement, were followed for 12 months. The pain was assessed at baseline and at 12 months using the Izbicki Pain Score, with a score decrease of >50% considered pain relief. Independent predictors of pain relief were derived from logistic regression analysis. RESULTS: Of 640 patients (mean age 36.71 [SD 12.19] years; 60.5% men), 436 (68.1%) had pain relief and 204 (31.9%) had persistent pain. On univariate analysis, older age, male sex, alcohol and tobacco intake, longer duration of symptoms, dilated MPD and MPD stricture were associated with persistent pain at 12 months (P<0.05). Consumption of alcohol (odds ratio [OR] 1.93, 95%CI 1.26-2.97), tobacco (OR 4.09, 95%CI 2.43-6.90), duration of symptoms (OR 1.02, 95%CI 1.01-1.04), MPD size (OR 1.22, 95%CI 1.11-1.33), and MPD stricture (OR 8.50, 95%CI 5.01-14.42) were independent predictors of persistent pain. CONCLUSIONS: Alcohol, tobacco, duration of symptoms, MPD size and stricture were independent predictors of persistent pain after successful ESWL. A multidisciplinary team approach that includes behavioral therapy and surgical options should be considered for such patients.

RESUMEN

BACKGROUND AND AIMS: The symptoms of reflux in achalasia patients undergoing peroral endoscopic myotomy (POEM) are believed to result from gastroesophageal reflux, and the current treatment primarily focuses on acid suppression. Nevertheless, other factors such as nonreflux acidification caused by fermentation or stasis might play a role. This study aimed to identify patients with "true acid reflux" who actually require acid suppression and fundoplication. METHODS: In this prospective large cohort study, the primary objective was to assess the incidence and risk factors for true acid reflux in achalasia patients undergoing POEM. Acid reflux with normal and delayed clearance defined true acid reflux, whereas other patterns were labeled as nonreflux acidification patterns on manual analysis of pH tracings. These findings were corroborated with a symptom questionnaire, esophagogastroscopy, esophageal manometry, and timed barium esophagogram at 3 months after the POEM procedure. RESULTS: Fifty-four achalasia patients aged 18 to 80 years (mean age, 41.1 ± 12.8 years; 59.3% men; 90.7% with type II achalasia) underwent POEM, which resulted in a significant mean Eckardt score improvement (6.7 to 1.6, P < .05). True acid reflux was noted in 29.6% of patients as compared with 64.8% on automated analysis. Acid fermentation was the predominant acidification pattern seen in 42.7% of patients. On multivariable logistic regression analysis, increasing age (odds ratio, 1.12; 95% confidence interval, 1.02-1.27; P = .04) and preprocedural integrated relaxation pressure (IRP; odds ratio, 1.13; 95% confidence interval, 1.04-1.30; P = .02) were significantly associated with true acid reflux in patients after undergoing POEM. CONCLUSIONS: A manual review of pH tracings helps to identify true acid reflux in patients with achalasia after undergoing POEM. Preprocedural IRP can be a predictive factor in determining patients at risk for this outcome. (Clinical trial registration number: NCT04951739.).

RESUMEN

OBJECTIVE: In patients with an intermediate likelihood of choledocholithiasis, European Society of Gastrointestinal Endoscopy (ESGE) guidelines recommend endoscopic ultrasound (EUS) or magnetic resonance cholangiopancreatography (MRCP) to diagnose choledocholithiasis to make the indication for endoscopic retrograde cholangiopancreatography (ERCP) treatment; there is no randomised control trial to compare both in this setting. DESIGN: Patients with suspected choledocholithiasis satisfying ESGE guideline's intermediate likelihood were screened for this single-centre randomised controlled trial between November 2019 and May 2020. The enrolled patients were randomised to either EUS or MRCP. ERCP was performed in stone positive cases or if clinical suspicion persisted during follow-up. Negative cases underwent a further 6-month clinical follow-up. Main outcome was accuracy (sensitivity/specificity) of both tests to diagnose choledocholithiasis, with ERCP or follow-up as a gold standard. RESULTS: Of 266 patients, 224 patients (mean age: 46.77±14.57 years; 50.9 % female) were enrolled; overall prevalence of choledocholithiasis was 49.6%, with a higher frequency in the MRCP group (63/112 vs 46/112 for EUS). Both sensitivity of EUS and MRCP were similarly high (92%-98%), without significant differences between the two groups. The negative predictive value and likelihood ratio + were significantly higher in EUS arm (p<0.05). The percentage of ERCPs either incorrectly halted back (false negatives: EUS: 2 vs MRCP: 5) or performed unnecessarily (false positives: EUS: 1 vs MRCP: 2) was low in both groups. CONCLUSION: The performance parameters of both EUS and MRCP are comparable for detecting choledocholithiasis in the intermediate-risk group of choledocholithiasis and the choice of a test should be based on local expertise, availability of resources and patient preference. TRIAL REGISTRATION NUMBER: NCT04173624.

RESUMEN

BACKGROUND: Acinetobacter baumannii has emerged as one of the leading causes of multidrug resistant nosocomial infections worldwide. It is able to survive in hospital environment and build up diverse resistance mechanisms making it difficult to treat with current antibiotics. Objective: It was to determine the frequency and patterns of Acinetobacter baumannii in intensive care units (ICU) settings. METHODS: A cross sectional study was carried out in the Department of Microbiology, Armed Forces Institute of Pathology, Rawalpindi, from 1st July 2017 to 30th June 2019. A total of 603 non-duplicate clinical specimens were received from intensive care units. Specimens yielding growth of multidrug resistant Acinetobacter baumannii, were evaluated as per standard protocol. The antimicrobial sensitivity testing was performed as per Clinical and Laboratory Standard Institute guidelines (2017-2018). RESULTS: Among Acinetobacter baumannii (310 isolates), 5% were multidrug resistant, 93% extensively drug resistant and 1% pan drug resistant. Percentage of carbapenem resistant strains was 92%. In drugs like tigecycline and polymyxin, resistance was noted as 73% and 1% respectively. High yield of this superbug was mainly obtained from respiratory specimens (43.5%), whereas 24% were detected from wound infections and 29% from other samples. . CONCLUSION: This study showed a rapidly increasing resistance in Acinetobacter baumannii. Therefore, polymyxin remains the only option in our intensive care units, but its usage as empirical therapy in our setting has led to the emergence of resistance to this drug. Implementing infection control practices, antimicrobial stewardship and restricted use of polymyxin can play a significant role in reducing health care burden.

RESUMEN

During the course of the COVID-19 pandemic, large-scale genome sequencing of SARS-CoV-2 has been useful in tracking its spread and in identifying Variants Of Concern (VOC). Besides, viral and host factors could contribute to variability within a host that can be captured in next-generation sequencing reads as intra-host Single Nucleotide Variations (iSNVs). Analysing 1, 347 samples collected till June 2020, we recorded 18, 146 iSNV sites throughout the SARS-CoV-2 genome. Both, mutations in RdRp as well as APOBEC and ADAR mediated RNA editing seem to contribute to the differential prevalence of iSNVs in hosts. Noteworthy, 41% of all unique iSNVs were reported as SNVs by 30th September 2020 in samples submitted to GISAID, which increased to [~]80% by 30th June 2021. Following this, analysis of another set of 1, 798 samples sequenced in India between November 2020 and May 2021 revealed that majority of the Delta (B.1.617.2) and Kappa (B.1.617.1) variations appeared as iSNVs before getting fixed in the population. We also observe hyper-editing events at functionally critical residues in Spike protein that could alter the antigenicity and may contribute to immune escape. Thus, tracking and functional annotation of iSNVs in ongoing genome surveillance programs could be important for early identification of potential variants of concern and actionable interventions.

RESUMEN

OBJECTIVE: To evaluate a direct antibiotic susceptibility testing method for blood culture.. METHODS: The cross-sectional comparative study was conducted at the Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from December 2016 to October 2017. Direct antimicrobial susceptibility testing was performed from positive blood culture bottles. Bacterial identification was done by using API 10S. Different antimicrobial panels were employed for Gram-negative rods (GNRs), gram-positive cocci (like suspected Staphylococci and Enterococci). Results were compared with conventional disk diffusion testing and very major, major and minor errors were calculated. Result agreement and kappa coefficient scores were generated for categorical agreement. SPSS 24 was used for data analysis. RESULTS: Of the 101 bacterial isolates, 82(81.2%) were Gram negative rods and 19(18.8%) were Grampositive cocci. Among 781 bacteria-antibiotic comparisons, the number of very major errors was 3(0.4%), major errors were 7(0.9%) and minor errors were 12(1.5%), while, 759(97.2%) comparisons yielded the same results. The kappa coefficient was 0.946, showing almost perfect agreement. Direct identification of Gram negative rods was successful in 53(64.6%) cases. CONCLUSIONS: Direct susceptibility testing of blood culture produced reliable results for majority of the antimicrobials.

RESUMEN

BACKGROUND: Acute respiratory illness caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) involved the whole globe within no time. Various studies published globally have shown variable severity of disease and mortality. The objective of our study was to describe clinical and epidemiological characteristics of the disease in our setup. METHODS: in this descriptive case series, individuals with signs and symptoms of Coronavirus disease-19 (COVID-19) and asymptomatic patients with history of close contact to confirmed COVID-19 patients were considered for SARS-CoV-2 Polymerase chain reaction (PCR) assay. Epidemiological and clinical features of only PCR positive cases were recorded. Data regarding hospitalization status, exposure to known COVID-19 patients, clinical feature and clinical outcome of patients was collected and interpreted. RESULTS: A total of 266 patients were found to be SARS-CoV 2 PCR positive which were included in the study. Mean age of patients was 39.45±31.9 years and majority of the patients in our study were male, i.e., 238 (89.5%). Most common clinical features among COVID-19 symptomatic patients were fever and dry cough followed by myalgias and sore throat. Eighteen (7%) out of 266 died in our setup. Time duration of viral shedding after initial positive PCR varied between 11 days to up to more than 55 days. CONCLUSION: Coronavirus disease-19 (COVID-19) can present with wide range of clinical spectrum and disease can be life threatening. Severity of disease, requirement of ICU care and mortality were directly related to age of the patient and underlying comorbidities. Rigorous precautionary measures are of utmost importance particularly in this high-risk population.

RESUMEN

OBJECTIVE: To determine the pattern of blood stream infections and their antibiotic susceptibility profile with infectivity predictors in a neonatal setting. METHODS: The descriptive cross-sectional study was conducted at the Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from December 1, 2016,to April 30, 2018, and comprised blood culture samples received in Bactec/BactAlert paediatric bottles from neonates aged 0-30 days admitted in the neonatal intensive care unit. The samples were processed as per the standard guidelines. Antibiotic susceptibility was checked as per guidelines of the Clinical and Laboratory Institute. VITEK 2 system was used for rapid identification and minimum inhibitory concentrations of the drugs. SPSS 24 was used for data analysis. RESULTS: Out of 640 samples, 172(27%) were culture-positive. Among them, 98(57%) were gramnegative rods, 50(29%) gram-positive cocci and 24(14%) were fungi. Of the 172 pathogens identified, Klebsiella pneumoniae was 39(22.7%) followed by Candida species 24(14%) and methicillin-resistant Coagulase-negative staphylococci 20(11.6%). Of Klebsiella pneumoniae isolates, 26(58%) were extended spectrum -lactamase producers. Among Acinetobacterbaumanii, 11(58%) were extensively drug resistant and Carbapenem-resistant strains were 20(91%). Also, 4(8%) isolates of Enterococcus faecium were vancomycin-resistant. CONCLUSIONS: Majority of the isolates causing blood stream infections in neonatal intensive care unit were multi drug resistant, posing a therapeutic challenge for the neo natologists .

RESUMEN

BACKGROUND: Maternal and neonatal outcomes in the immediate post-delivery period are critical indicators of quality of care. Data on childbirth outcomes in low-income settings usually require home visits, which can be constrained by cost and access. We report on the use of a call center to measure post-discharge outcomes within a multi-site improvement study of facility-based childbirth in Uttar Pradesh, India. METHODS: Of women delivering at study sites eligible for inclusion, 97.9% (n = 157,689) consented to follow-up. All consenting women delivering at study facilities were eligible to receive a phone call between days eight and 42 post-partum to obtain outcomes for the seven-day period after birth. Women unable to be contacted via phone were visited at home. Outcomes, including maternal and early neonatal mortality and maternal morbidity, were ascertained using a standardized script developed from validated survey questions. Data Quality Assurance (DQA) included accuracy (double coding of calls) and validity (consistency between two calls to the same household). Regression models were used to identify factors associated with inconsistency. FINDINGS: Over 23 months, outcomes were obtained by the call center for 98.0% (154,494/157,689) consenting women and their neonates. 87.9% of call center-obtained outcomes were captured by phone call alone and 12.1% required the assistance of a field worker. An additional 1.7% were obtained only by a field worker, 0.3% were lost-to-follow-up, and only 0.1% retracted consent. The call center captured outcomes with a median of 1 call (IQR 1-2). DQA found 98.0% accuracy; data validation demonstrated 93.7% consistency between the first and second call. In a regression model, significant predictors of inconsistency included cases with adverse outcomes (p<0.001), and different respondents on the first and validation call (p<0.001). CONCLUSIONS: In areas with widespread mobile cell phone access and coverage, a call center is a viable and efficient approach for measurement of post-discharge childbirth outcomes.

RESUMEN

Multiple myeloma is rare B cell malignancy that affects elderly. Therapeutic regimens consist of high dose chemotherapy followed by haematopoietic stem cell transplantation (HSCT). Both humoral and cell mediated immunities are compromised in these patients, leading to increased susceptibility to infections. Here, we report a case of 62-year male with multiple myeloma who developed infection with three viruses from herpes family during the first cycle of chemotherapy.

RESUMEN

BACKGROUND: There are few published standards or methodological guidelines for integrating Data Quality Assurance (DQA) protocols into large-scale health systems research trials, especially in resource-limited settings. The BetterBirth Trial is a matched-pair, cluster-randomized controlled trial (RCT) of the BetterBirth Program, which seeks to improve quality of facility-based deliveries and reduce 7-day maternal and neonatal mortality and maternal morbidity in Uttar Pradesh, India. In the trial, over 6300 deliveries were observed and over 153,000 mother-baby pairs across 120 study sites were followed to assess health outcomes. We designed and implemented a robust and integrated DQA system to sustain high-quality data throughout the trial. METHODS: We designed the Data Quality Monitoring and Improvement System (DQMIS) to reinforce six dimensions of data quality: accuracy, reliability, timeliness, completeness, precision, and integrity. The DQMIS was comprised of five functional components: 1) a monitoring and evaluation team to support the system; 2) a DQA protocol, including data collection audits and targets, rapid data feedback, and supportive supervision; 3) training; 4) standard operating procedures for data collection; and 5) an electronic data collection and reporting system. Routine audits by supervisors included double data entry, simultaneous delivery observations, and review of recorded calls to patients. Data feedback reports identified errors automatically, facilitating supportive supervision through a continuous quality improvement model. RESULTS: The five functional components of the DQMIS successfully reinforced data reliability, timeliness, completeness, precision, and integrity. The DQMIS also resulted in 98.33% accuracy across all data collection activities in the trial. All data collection activities demonstrated improvement in accuracy throughout implementation. Data collectors demonstrated a statistically significant (p = 0.0004) increase in accuracy throughout consecutive audits. The DQMIS was successful, despite an increase from 20 to 130 data collectors. CONCLUSIONS: In the absence of widely disseminated data quality methods and standards for large RCT interventions in limited-resource settings, we developed an integrated DQA system, combining auditing, rapid data feedback, and supportive supervision, which ensured high-quality data and could serve as a model for future health systems research trials. Future efforts should focus on standardization of DQA processes for health systems research. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT02148952 . Registered on 13 February 2014.

RESUMEN

OBJECTIVE: To study mental and physical health of pregnant women and compare the differences between those residing in urban and rural settings. METHODS: A Cross-Sectional Survey was conducted on pregnant women (n=179) in urban and rural areas of Islamabad in January 2009. SF-12, a validated instrument for mental and physical health assessment was used and translated into Urdu. Responses were decoded as per SF-12 analysis protocol. Independent sample t-test was done to compare the quantitative variables. The level of statistical significance was p<0.05. The survey was filled either by the participant or the research team and was anonymous. All the researchers were trained in the interview technique in order to make sure that each question carried the same meaning during the actual survey. This was done to standardize the survey methodology. RESULTS: A total of 179 survey forms were collected, 83 and 96 from both rural and urban areas respectively. Role Limitations because of Physical Problems (p=0.020), General Health Perceptions (p=0.001) and Role Limitations because of Emotional Problems (p=0.023) had statistically significantly lower scores in rural women as compared to urban women. CONCLUSION: Self-perceived mental and physical health was better in urban pregnant women than in rural women.
