The role of endoscopy in pathologies of the bile duct and gallbladder has seen notable advancements over the past two decades. With advancements in stent technology, such as the development of lumen-apposing metal stents, and adoption of endoscopic ultrasound and electrosurgical principles in therapeutic endoscopy, what was once considered endoscopic failure has transformed into failure of an approach that could be salvaged by a second- or third-line endoscopic strategy. Incorporation of these advancements in routine patient care will require formal training and multidisciplinary acceptance of established techniques and collaboration for advancement of experimental techniques to generate robust evidence that can be utilized to serve patients to the best of our ability., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2024.

Leiomyoma is the most prevalent benign tumor of the female reproductive system. Benign metastasizing leiomyoma (BML) is a rare phenomenon that presents at distant sites, typically the lungs, exhibiting histopathological features similar to the primary uterine tumor in the absence of malignancy features in both. Fumarate hydratase-deficient uterine leiomyoma (FH-d UL) is an uncommon subtype among uterine smooth muscle tumors (0.5-2%), showing distinctive histomorphology and FH inactivation. The majority of FH-d ULs are sporadic, caused by somatic FH inactivation, while a minority of cases occur in the context of the hereditary leiomyomatosis and renal cell carcinoma (HLRCC) syndrome caused by germline FH inactivation. Metastasizing FH-d UL has not been well documented and might be under-reported. Here, we present two cases (21- and 34-year-old females) who presented with metastasizing FH-d UL after myomectomy/hysterectomy with histologically proven multiple lung metastases in both, in addition to multi-organ involvement in one case (cervical-thoracic lymph nodes, left kidney, perihepatic region, left zygomatic bone, and soft tissues). Pathological examination confirmed FH-d leiomyomas in the primary/recurrent uterine tumors, multiple lung lesions, and a renal mass. The minimal criteria for diagnosis of leiomyosarcoma were not fulfilled. Genetic testing revealed germline pathogenic FH variants in both cases (c.1256C > T; p.Ser419Leu in Case 1 and c.425A > G; p.Gln142Arg in Case 2). These novel cases highlight a rare but possibly under-recognized presentation of FH-d BML. Our study suggests that FH-d BML cases might be enriched for the HLRCC syndrome., (© 2024. The Author(s).)

With the increasing use of next generation sequencing in soft tissue pathology, particularly in neoplasms not fitting any World Health Organization (WHO) category, the spectrum of EWSR1 fusion-associated soft tissue neoplasms has been expanding significantly. Although recurrent EWSR1::ATF1 fusions were initially limited to a triad of mesenchymal neoplasms including clear cell sarcoma of soft tissue, angiomatoid fibrous histiocytoma and malignant gastrointestinal neuroectodermal tumor (MGNET), this family has been expanding. We herein describe 4 unclassified extra-abdominal soft tissue (n = 3) and bone (n = 1) neoplasms displaying epithelioid and round cell morphology and carrying an EWSR1::ATF1 fusion. Affected were 3 males and 1 female aged 20-56 years. All primary tumors were extra-abdominal and deep-seated (chest wall, mediastinum, deltoid, and parapharyngeal soft tissue). Their size ranged 4.4-7.5 cm (median, 6.2). One patient presented with constitutional symptoms. Surgery with (2) or without (1) neo/adjuvant therapy was the treatment. At last follow-up (8-21 months), 2 patients developed progressive disease (1 recurrence; 1 distant metastasis). The immunophenotype of these tumors is potentially misleading with variable expression of EMA (2 of 3), pankeratin (2 of 4), synaptophysin (2 of 3), MUC4 (1 of 3), and ALK (1 of 3). All tumors were negative for S100 and SOX10. These observations point to the existence of heretofore under-recognized group of epithelioid and round cell neoplasms of soft tissue and bone, driven by EWSR1::ATF1 fusions, but distinct from established EWSR1::ATF1-associated soft tissue entities. Their overall morphology and immunophenotype recapitulate that of the emerging EWSR1/FUS::CREB fusion associated intra-abdominal epithelioid/round cell neoplasms. Our cases point to a potentially aggressive clinical behavior. Recognizing this tumor type is mandatory to delineate any inherent biological and/or therapeutic distinctness from other, better-known sarcomas in the differential diagnosis including sclerosing epithelioid fibrosarcoma., (© 2024.

A proportion of patients who undergo intraoperative cholangiogram (IOC) do not have bile duct stones at the time of endoscopic retrograde cholangiopancreatography (ERCP), either due to the spontaneous passage of stones or a false-positive IOC. Glucagon has been utilized as an inexpensive tool to allow the passage of micro-choledocholithiasis to the duodenum and resolve filling defects caused by stones or air bubbles. The purpose of our study is to understand the change in diagnostic accuracy of IOC to detect choledocholithiasis with intraoperative glucagon. We conducted a retrospective study at a tertiary care center on adult patients who underwent laparoscopic cholecystectomy with IOC. The diagnostic accuracy of IOC was assessed before and after the administration of intravenous glucagon. Of 1455 patients, 374 (25.7%) received intraoperative glucagon, and 103 of these 374 patients (27.5%) showed resolution of the filling defect with the passage of contrast to the duodenum. Pre- and post-glucagon administration comparison showed enhancement in specificity from 78% to 83%, an increase in positive predictive value from 67.3% to 72.4%, and an improvement in the diagnostic accuracy of IOC from 81.5% to 84.3%. Our findings suggest that intraoperative glucagon administration carries the potential to reduce the rate of false-positive IOCs, thereby reducing the performance of unnecessary ERCPs.

Monitoring heavy metal accumulation is essential for assessing the viability of aquatic ecosystems. Our methodology involved integrating analysis of immunological, stress, inflammatory, and growth-related gene expression in male and female Nile tilapia with on-site recordings of physicochemical parameters. Additionally, we assessed the effect of different physicochemical parameters on heavy metal bioavailability and residual concentration in fish and water. Samples of fish and water were gathered from three different localities: Lake Brullus, a brackish lake sited in northern Egypt; Lake Nasser, an artificial freshwater reservoir located in southern Egypt; and El-Qanater El-Khayria, a middle-freshwater location belonging to the Rashid branch of the river Nile. The assessment of heavy metal residues (Fe, Cu, Zn, Mn, and Ni) revealed that their concentrations were higher in fish specimens compared to their counterparts in water (except for Ni). In addition, Lake Brullus emerges as the most polluted area, exhibiting elevated levels of heavy metals concentrations in water and fish specimens. In contrast, Lake Nasser showed the least degree of heavy metals pollution. Gene expression analysis revealed gender-specific responses to heavy metal exposure at the three investigated water bodies. The expression of hepatic antioxidant genes (GST and MT) and inflammatory-related genes (CC-chemokine and TNFα) increased in males compared to females. In females, the immune and pro-inflammatory-related genes (IgM and CXC2-chemokine) transcripts were upregulated. Additionally, growth-related genes were downregulated in both Lake Brullus and El-Qanater; on the contrary, fish samples from Lake Nasser exhibited a normal expression pattern of growth-related genes. Stress-related genes (HSP70 and HSP27) showed significant downregulation in gills of both genders from Lake Brullus. The minimal presence of heavy metal contaminants in Lake Nasser seems to endorse the normal patterns of gene expression across all gene categories. A potential gender-specific gene expression response towards pollution was noticed in genes associated with inflammation and antioxidant activities. This highlights the importance of considering gender-related responses in future environmental assessments., (© 2024. The Author(s).)

Background and Aims: This study analyzed the optimal biliary stenting strategy for palliation in cholangiocarcinoma (CCA)., Methods: This was a retrospective study of patients with CCA who underwent biliary drainage from 1997 to 2023. A per-patient analysis of percutaneous transhepatic biliary drainage (PTBD) rates, the median number of ERCPs, and overall survival (OS) and a per-procedure analysis of clinical success (CS), stent-specific adverse events (AEs), and mean time to repeat ERCP by stent type and laterality (unilateral and bilateral) are presented., Results: A total of 333 patients underwent 1050 ERCPs, 85% with plastic stents (PSs). PTBD was eventually done in 23% of PS patients, 35% of whom had their PS removed before PTBD. ERCPs with the use of self-expandable metal stents (SEMSs)/unilateral SEMSs had higher CS (89%/91%) versus PSs/unilateral plastic stents (uPSs) (85% both) and PSs within SEMSs (PS-SEMSs)/uPS-SEMSs (71%/74%; P = .013/P = .054). Compared with PSs, SEMSs and PS-SEMSs were associated with higher stent-specific AEs (odds ratios [ORs]: SEMSs 4.85 [95% confidence interval (CI), 3.23-7.27], PS-SEMSs 9.99 [95% CI, 5.33-18.71]; P < .001). Straight PSs were associated with more stent-specific AEs compared with double-pigtail stents (OR 6.74 [95% CI, 3.95-11.45]; P < .001). More 7F stents were used in cases with balloon dilation (BD) (109 with BD vs 88 without BD; P < .001). BD had a 79% CS rate versus 87% without BD (P < .001). Cases with pus on ERCP and those with BD had a shorter mean time to repeat ERCP. On regression analyses, higher Bismuth class, PS use, and PS-SEMS use were associated with a shorter mean time to repeat ERCP. Fifty-two percent of patients in the bilateral SEMS arm died from cholangitis (P = .005)., Conclusions: The relatively higher CS rate of SEMSs is countered by the higher stent-specific AE rate. PSs can be removed and may better facilitate PTBD. Within PS types, double-pigtail stents may have fewer stent-specific AEs. Cases requiring BD and with endoscopic evidence of pus may benefit from earlier reintervention., Competing Interests: Disclosure The following author disclosed financial relationships: J. H.

Background: The association of neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO) with functional status in the general Medicare population are not well established. Objectives: This study examined patient-reported survey data linked with Medicare claims to describe the burden of these vision-threatening retinal diseases (VTRDs) among Medicare beneficiaries. Methods: Medicare Current Beneficiary Survey data linked with Medicare Fee-for-Service claims data from 2006 to 2018 were used in a nationally representative retrospective pooled cross-sectional population-based comparison study. Outcomes between community-dwelling beneficiaries with nAMD (n = 1228), DME (n = 101), or RVO (n = 251) were compared with community-dwelling beneficiaries without any VTRDs (n = 104 088), controlling for baseline demographic and clinical differences. Beneficiaries with a diagnosis of nAMD, DME, or RVO during the data year were included; those with other VTRDs were excluded. Outcomes included vision function and loss, overall functioning as assessed by difficulties with activities of daily living (ADLs) and instrumental ADLs (iADLs), anxiety/depression, falls, and fractures. Results: In patient cohorts with nAMD, DME, and RVO, approximately one-third (34.2%-38.3%) reported "a little trouble seeing" (vs 28.3% for controls), and 26%, 17%, and 9%, respectively, reported "a lot of trouble seeing/blindness" (vs 5% of controls). Difficulty walking and doing heavy housework were the most reported ADLs and iADLs, respectively. Compared with those without VTRDs, beneficiaries with nAMD had higher odds of diagnosed vision loss (odds ratio [OR], 5.39; 95% confidence interval, 4.06-7.16; P < .001) and difficulties with iADLs (odds ratio, 1.41; 95% confidence interval, 1.11-1.80; P = .005); no differences were observed for DME or RVO vs control. After adjusting for age, sex, race/ethnicity, poverty status, comorbidities, and other relevant covariates, nAMD, DME, and RVO were not significantly associated with anxiety/depression, falls, or fractures. Discussion: Patients with nAMD or DME were more likely to report severe visual impairment than those without VTRDs, although only those with nAMD were more likely to be diagnosed with vision loss. Conclusions: Patients with nAMD continue to experience more vision impairment and worse functional status compared with a similar population of Medicare beneficiaries despite availability of therapies like antivascular endothelial growth factor to treat retinal disease., Competing Interests: V.G., A.M., C.D.N., and I.M.A. are employees of Genentech, Inc. G.O., J.B., and D.B. have consultancies with Genentech, Inc. F.S.A. has consultancies with Allergan/AbbVie, Apellis, EyePoint, Genentech, Inc., and Regeneron and is on the speakers’ bureau of Apellis.

Objectives: To compare efficacy of 10-mg of vonoprazan daily & on alternate days by Gastroesophageal Reflux Disease Symptom Assessment Scale (GSAS)., Method: This prospective interventional cohort was done at Department of Medicine/Gastroenterology Dow Medical College, Karachi, Pakistan during the period August 2022 & January 2023. Potential participants fulfilling inclusion and exclusion criteria were asked to fill out GSAS questionnaires after their written consent. Patients were allocated in to two groups using random tables. Group-A was given Tab Vonoprazan 10-mg daily for two weeks. Group-B was given Tab Vonoprazan 10-mg on alternate day. GSAS was scored by totaling scores across symptoms and then they are divided by the total number of non-missing symptom scores. Both groups were assessed week-0 & week-2., Results: Only 90 proformas that were completely filled were included, Group-A had 30 males and 15 females while Group-B had 29 males and 16 females. No significant difference in score was found in GSAS score at week-0 except that in item 'gurgling' while at week two there was no significant difference between any of the items. Total GSAS score were significantly lower at Week-2 than at week-0 (p = <.001)., Conclusions: Vonoprazan of 10-mg on alternate day is equally effective as 10-mg daily in maintenance of GERD patients at two weeks., (Copyright: © Pakistan Journal of Medical Sciences.)

Objectives: To assess medical students' perceptions regarding learning, teachers, academics, atmosphere at campus and social self-perceptions at Dow University of Health Sciences using Dundee Ready Education Environment Measure (DREEM) Inventory., Method: This cross-sectional observational study was conducted from March 1 st , 2022 to September 30 th , 2022. All medical students at Dow University of Health Sciences were offered to participate. All students were given the choice to respond to DREEM questionnaire via online Form or printed copy anonymously. The DREEM Inventory measures five domains of students' perceptions of a given institution. Comparison of responses between different years and institution was carried out by χ 2 test. Means scores were compared by Student's t-test and ANOVA, p-value of ≤.05 was taken as significant., Results: Total of 1054 out of 1750 (60.23%) students submitted fully completed forms and were included, out of these 632 (60.0%) belonged to Dow Medical College & 422 (40.0%) belonged to Dow International Medical College. The mean ±SD of total score of DREEM by DMC students was 100.07 ±31.46 and that of DIMC was 100.52 ±32.73. According to DREEM Global scoring both colleges scores fell into category of "many problems". Analysis according to domains showed that maximum score was given to 2 nd domain of their "perception regarding teachers" and minimum score was allocated to 5 th domain regarding "social self-perceptions"., Conclusion: Overall Students perceived environment at DUHS as "many problems" category. This needs to be investigated for betterment of Educational Environment (EE) at campus., (Copyright: © Pakistan Journal of Medical Sciences.)

This report describes a case of bilateral, simultaneous central serous chorioretinopathy (CSCR) in a young woman on oral contraceptive pills (OCP). A 21-year-old woman with a negative past medical history presented with sudden onset of bilateral decreased vision shortly after starting OCP. Comprehensive ocular examination revealed bilateral central serous chorioretinopathy (CSCR), confirmed on retinal optical coherence tomography (OCT) and intravenous fluorescein angiography. The patient was instructed to discontinue OCP, and three weeks later, there was complete resolution of the visual symptoms and of the bilateral serous retinal detachments, documented on OCT.

Purpose: Automated machine learning (AutoML) has emerged as a novel tool for medical professionals lacking coding experience, enabling them to develop predictive models for treatment outcomes. This study evaluated the performance of AutoML tools in developing models predicting the success of pneumatic retinopexy (PR) in treatment of rhegmatogenous retinal detachment (RRD). These models were then compared with custom models created by machine learning (ML) experts., Design: Retrospective multicenter study., Participants: Five hundred and thirty nine consecutive patients with primary RRD that underwent PR by a vitreoretinal fellow at 6 training hospitals between 2002 and 2022., Methods: We used 2 AutoML platforms: MATLAB Classification Learner and Google Cloud AutoML. Additional models were developed by computer scientists. We included patient demographics and baseline characteristics, including lens and macula status, RRD size, number and location of breaks, presence of vitreous hemorrhage and lattice degeneration, and physicians' experience. The dataset was split into a training (n = 483) and test set (n = 56). The training set, with a 2:1 success-to-failure ratio, was used to train the MATLAB models. Because Google Cloud AutoML requires a minimum of 1000 samples, the training set was tripled to create a new set with 1449 datapoints. Additionally, balanced datasets with a 1:1 success-to-failure ratio were created using Python., Main Outcome Measures: Single-procedure anatomic success rate, as predicted by the ML models. F2 scores and area under the receiver operating curve (AUROC) were used as primary metrics to compare models., Results: The best performing AutoML model (F2 score: 0.85; AUROC: 0.90; MATLAB), showed comparable performance to the custom model (0.92, 0.86) when trained on the balanced datasets. However, training the AutoML model with imbalanced data yielded misleadingly high AUROC (0.81) despite low F2-score (0.2) and sensitivity (0.17)., Conclusions: We demonstrated the feasibility of using AutoML as an accessible tool for medical professionals to develop models from clinical data. Such models can ultimately aid in the clinical decision-making, contributing to better patient outcomes. However, outcomes can be misleading or unreliable if used naively. Limitations exist, particularly if datasets contain missing variables or are highly imbalanced. Proper model selection and data preprocessing can improve the reliability of AutoML tools., Financial Disclosures: Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article.

The International Cardio-Metabolic Forum held a plenary session to establish a multinational consensus on the challenges faced in diabetes management within lower-middle-income countries (LMICs) and their potential solutions. Stakeholders, including patients, family/caretakers, healthcare professionals, and healthcare policymakers & organizations, participated in discussions. The audience of 280 doctors from 15 different countries (Pakistan, Qatar, Sri Lanka, Kenya, Myanmar, Georgia, Nigeria, Philippines, Uzbekistan, Iraq, Tanzania, Cambodia, Kazakhstan, South Sudan and Libya) was divided into 4 groups led by Group Leaders to represent each stakeholder group. Questionnaires addressing key challenges and solutions specific to each group were used to facilitate consensus development. Participants voted on relevant options based on their clinical experience. SLIDO software was used for polling, generating separate results for each group. The insights shared by healthcare professionals highlighted the importance of improving medication accessibility and cost-effectiveness for patients, emphasizing the need for adherence to treatment plans and lifestyle modifications. The significance of balanced nutrition with low glycemic index food for enhancing quality of life was recognized. Caregivers of diabetic patients with comorbidities face increasing demands for care, particularly in relation to age-related milestones. Healthcare professionals emphasized the challenges posed by cultural beliefs and health awareness, underscoring the importance of teamwork and early referral for managing comorbidities. Healthcare policymakers need to focus on disease education, awareness programs, screening guidelines, and advocacy for community and clinical screening. By addressing these challenges, a more comprehensive and effective approach to diabetes management can be achieved in LMICs, ultimately improving outcomes for individuals with diabetes., Competing Interests: Conflict of Interest: None., (Copyright: © Pakistan Journal of Medical Sciences.)

Introduction: The incremental yield of I-Scan virtual chromoendoscopy compared to high-definition white light endoscopy (HD-WLE) in detection of colorectal adenomas has not been thoroughly elucidated., Methods: A systematic search from inception to April 2023 was conducted to identify randomized controlled trials (RCTs) comparing I-Scan to HD-WLE for detection of adenomas. A random effects model was used to compute risk difference (RD) with corresponding 95% confidence intervals in adenoma detection rate (ADR). Influence analysis was done to assess robustness of findings. The number needed to diagnose was computed. Heterogeneity was assessed using the I 2 statistic and explored further by subgroup analyses defined a priori. Certainty in effect estimates was assessed using the GRADE approach., Results: We identified four studies (I-Scan n = 730, HD-WLE n = 765). I-Scan increased adenoma detection by 9% (risk difference (RD), 0.09; 0.04, 0.14; I 2 02%; certainty, low). Influence analysis revealed that the gain in yield remained statistically significant with exclusion of all but one study. The number needed to capture one additional adenomatous polyp with I-Scan use was 11.2. I-Scan 1 use was associated with a statistically significant gain in ADR, whereas no significant difference in ADR was noted with I-Scan use on subgroup analysis., Discussion: In conclusion, I-Scan increases the yield of adenoma detection by 9% compared to HD-WLE, with low certainty in the estimate of this effect. Data on the gain in yield of detecting large polyps, sessile serrated lesions, and on the impact of formally training endoscopists and trainees in I-Scan use and similar technology on adenoma detection rate are needed., (© 2023.

Objective: To determine correlation of HbA1c with serum iron and transferrin saturation in non-diabetic patients with iron deficiency., Methods: This cross-sectional comparative study was conducted at Dr Ruth KM Pfau Civil Hospital Karachi from 15 th September 2021 to 14 th March 2022, on non-diabetic patients based on fasting blood sugar (FBS) of <100 mg/dl. Patients were divided into two groups. Group one included patients having iron deficiency anemia (ID), whereas group two included same number of age and sex matched healthy subjects taken as controls, without ID. Blood sample was taken for HbA1c, CBC, serum iron and total iron binding capacity. Transferrin saturation (TSAT) was calculated. Comparison of quantitative variables with ID and non-ID group was done by Student's t-test. Correlation of HbA1c with iron &TSAT was done in both groups using Kendal tau-b test, as data was not normally distributed., Results: Out of 230 patients, 83 (36.1%) were males while 147(63.9%) were females. Mean age of patients was 43.7±13.28 years. Mean HbA1c level was significantly high in ID group (5.89±0.43) as compared to non-ID group (5.52±0.50) with a p-value <.001. The HbA1c levels correlated negatively with hemoglobin, serum iron levels and transferrin saturation with a p-value <.001., Conclusion: Low serum Iron and TSAT was related to elevation in HbA1c value. Iron deficiency needs to be corrected before HbA1c interpretation., Competing Interests: Conflict of interest: All authors disclose no conflict of interest., (Copyright: © Pakistan Journal of Medical Sciences.)

Background: RICAP is a recognized adverse effect of radiation therapy (RT) that can adversely affect cancer patients' quality of life. Data on the clinical characteristics and outcomes of RICAP are scarce. We aimed to analyze the clinical and endoscopic characteristics of acute or chronic radiation-induced colitis and proctopathy (ARICAP and CRICAP) based on symptom onset after RT (≤ or >45 days, respectively)., Methods: This is a retrospective observational study of a single tertiary cancer center, from January 2010 and December 2018, of cancer patients with endoscopically confirmed ARICAP and CRICAP. We conducted univariate and multivariate logistic regression analyses to associate clinical variables with endoscopic and medical outcomes., Results: One hundred and twelve patients were included (84% Caucasian; 55% female; median age of 59 years); 46% had ARICAP with non-bloody diarrhea as the predominant symptom, whereas 55% had CRICAP with mostly bloody diarrhea. Neovascularization was the most frequent finding on endoscopy, followed by bleeding. ARICAP patients more often received medical management ( p < 0.001), whereas CRICAP patients with bleeding more often received argon plasma coagulation (APC) ( p = 0.002). Female sex and undergoing less-intense RT treatments were more associated with medical treatment; bleeding clinically and during the endoscopy was more associated with APC treatment. However, APC treatment did not significantly reduce bleeding recurrence or RICAP symptoms., Conclusion: Patients with ARICAP and CRICAP experience different symptoms. Medical management should be considered before endoscopic therapy. APC may be useful in patients with endoscopically apparent bleeding.

Background and Aims: The relative utility of self-expanding metal stent (SEMS) insertion for malignant colon obstruction (MCO) due to extra-colonic malignancy (ECM) versus intra-colonic malignancy (ICM) is understudied., Methods: A systematic search was done from inception-April 2021 to identify reports of safety and efficacy of SEMS insertion for the treatment of MCO-ECM versus MCO-ICM. A meta-analysis of proportions, comparative meta-analysis to compute relative risks (RR), and mean differences (MD) was performed. Subgroup analyses and influence analyses were conducted. The certainty in estimates of effect(s) was assessed using the GRADE approach., Results: Eight non-randomized studies were identified; 46% (39-53%) and 63% (59-67%) of patients in the ECM and ICM groups were male. Most obstructions were in the rectosigmoid colon in both ECM and ICM groups. SEMS insertion in MCO-ECM was associated with an increased risk of technical failure compared to MCO-ICM (RR 2.92; 1.13-7.54; Certainty: Very Low). Risk of clinical failure of SEMS was higher in MCO-ECM compared to MCO-ICM (RR 2.88; 1.58-2.52; Certainty: Very Low). The risk of clinical failure remained significant throughout the influence analysis, as well as on subgroup analysis. There was no significant difference in the risk of adverse events or luminal perforation with SEMS insertion among patients with MCO-ECM and MCO-ICM. On influence analysis, removal of one study unveiled a significant increase in the risk of luminal perforation in MCO-ECM (RR 3.22; 1.44-7.19; p = 0.004)., Conclusion: SEMS for MCO-ECM may have a technical success rate comparable to or questionably worse than MCO-ICM, with low certainty in estimate of effects. SEMS deployment in MCO-ECM carries a higher risk of clinical failure, with a questionably higher risk of luminal perforation., (© 2023.

Introduction: Chronic kidney disease (CKD) is associated with multimorbidity and high treatment burden. Pill-burden is one component of the overall treatment burden. However, little is known about its magnitude and contribution to the overall treatment burden among patients with advanced stages of CKD. This study aimed to quantify the magnitude of pill-burden in dialysis-dependent vs. non-dialysis-dependent advanced-stage CKD patients and its association with treatment burden., Methods: This was a cross-sectional study for the assessment of pill-burden and treatment burden among non-dialysis and hemodialysis (HD)-dependent CKD patients. Pill-burden was quantified as "number of pills/patient/week" through electronic medical record, while treatment burden was assessed using the "Treatment Burden Questionnaire (TBQ)". Furthermore, oral and parenteral medication burden was also quantified. Data were analyzed using both descriptive and inferential analysis, including Mann - Whitney U test and two-way between groups analysis of variance (ANOVA)., Results: Among the 280 patients included in the analysis, the median (IQR) number of prescribed chronic medications was 12 (5.7) oral and 3 (2) parenteral medications. The median (IQR) pill-burden was 112 (55) pills/week. HD patients experienced higher pill-burden than non-dialysis patients [122 (61) vs. 109 (33) pills/week]; however, this difference did not reach statistical significance (p = 0.81). The most commonly prescribed oral medications were vitamin D (90.4%), sevelamer carbonate (65%), cinacalcet (67.5%), and statins (67.1%). Overall, patients who had high pill-burden (≥112 pills/week) had significantly higher perceived treatment burden compared to low pill-burden patients (<112 pills/week) [47(36.2) vs. 38.5(36.7); p = 0.0085]. However, two-way ANOVA showed that dialysis status is the significant contributor to the treatment-burden in the high overall pill-burden group (p < 0.01), the high oral-medication-burden group (p < 0.01), and the high parenteral-medication-burden group (p = 0.004)., Conclusions: Patients with advanced CKD experienced a high pill-burden, which increases the treatment burden; however, the dialysis status of the patient is the main factor affecting the overall treatment burden. Future intervention studies should target this population with an aim to reduce polypharmacy, pill-burden, and treatment burden, which may ultimately improve CKD patients' quality of life., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Author(s).)

Cancer is one of the foremost health problems worldwide and is among the leading causes of death in the United States. Gastrointestinal tract cancers account for almost one third of the cancer-related mortality globally, making it one of the deadliest groups of cancers. Early diagnosis and prompt management are key to preventing cancer-related morbidity and mortality. With advancements in technology and endoscopic techniques, endoscopy has become the core in diagnosis and management of gastrointestinal tract cancers. In this extensive review, the authors discuss the role endoscopy plays in early detection, diagnosis, and management of esophageal, gastric, colorectal, pancreatic, ampullary, biliary tract, and small intestinal cancers., (© 2022 The Authors.

Objective: To determine the effect of Remdesivir on liver enzymes and renal functions in SARS-CoV-2 patients., Methods: This prospective cohort study was conducted at Dr. Ruth KM Pfau, Civil Hospital Karachi between 1 st December 2021 to 31 st January, 2022. All patients of severe SARS-CoV-2 infection who received Inj. Remdesivir for five days as per protocol of SARS-CoV-2 management were included. Biodata of selected patients including age, gender, diabetic, hypertensive status was recorded. Patients Liver Function Tests and Serum Creatinine were performed on days 0, 3, 5, 7 and 14., Result: This study included 85 patients, out of which 55 (64.7%) were males and 30 (35.3%) were females. Out of 85 patients, Remdesivir was stopped in 3 (3.5%) patients. Among these three patients Remdesivir was stopped in one patient on day three because of decrease in CrCl to <30 ml/min. His CrCl improved after stopping Remdesivir. In the remaining two patients, Remdesivir was stopped due to increase in ALT to greater than 10 times from normal values on day three. Similarly, in these two patients the ALT improved after stopping Remdesivir., Conclusion: Only three patients developed adverse effects resulting in stopping of Remdesivir, however these were reversible on stopping the drug. Therefore, Remdesivir is a relatively safe drug and well tolerated in SARS-CoV-2 patients., Competing Interests: Conflict of interest: None., (Copyright: © Pakistan Journal of Medical Sciences.)

Objective: To present and validate psychometric properties of Urdu version CLDQ, yet another objective was to do exploratory factorial analysis (EFA) of CLDQ Urdu version., Methods: This Cross-sectional Analytical Study was conducted at Dr. Ruth K.M. Pfau Civil Hospital Karachi during the period Nov. 15, 2021 to Jan. 30, 2022. CLDQ Urdu questionnaire was self-administered by the patients. The questionnaire consisted of 29 items and responses were recorded on 7-point Likert type scale. Reliability testing was done by Cronbach's α, test value of >0.7 is taken as reliable. Exploratory factor analysis (EFA) was conducted with principal component analysis with varimax rotation. Adequacies for conduction of EFA depended on Kaiser-Meyer-Olkin (KMO) value of ≥0.5 and Bartlett's Test of Sphericity (BTS) of ≤0.05. Mean CLDQ Urdu scores were also compared with Child Class using ANOVA and post-hoc analysis was done., Results: A total of 320 patients were selected after informed consent. All conditions for adequate EFA were met (Cronbach's α =.949; KMO = .846; BTS ≤.001). Mean CLDQ Urdu score was 156.74 in male and 133.27 in female ( p <.001). Child Class-A had best quality of life with score of 186.63 ±6.91 and Child Class-C had the worst with scores of 109.78 ±21.33. EFA resulted in reduction of domains to 4 (Muscular Symptoms, Emotional Symptoms, Abdominal Symptoms & Somnolence) & reduced the number of items from 29 to 11., Conclusion: Urdu CLDQ version is validated in our settings. EFA resulted in reductions in number of domains and items. CLDQ Urdu showed that quality of life decreases significantly with Child Class., Competing Interests: Conflict of Interest: All authors state no disclosures for any financial conflict of interest., (Copyright: © Pakistan Journal of Medical Sciences.)

Abstract: Endoscopic retrograde appendicitis therapy (ERAT) has emerged as a promising, non-invasive treatment for acute uncomplicated appendicitis (AUA). ERAT involves cannulation, appendicography, appendiceal stone extraction, appendiceal lumen irrigation, and stent deployment. Recent randomized trials comparing ERAT to laparoscopic appendectomy (LA) have provided promising results in terms of safety and efficacy of ERAT. If the current trajectory of research and development is maintained, ERAT will likely become a strong contender for the standard of care for AUA. Standardized training and credentialing for ERAT, akin to procedures established for endoscopic retrograde cholangiopancreatography, will be pivotal to global adoption of this modality., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Strabismus is a visual disorder where the eyes are misaligned and point in different directions. Untreated strabismus can lead to amblyopia, loss of binocular vision, and social stigma due to its appearance. Since it is assumed that knowledge is pertinent for early screening and prevention of strabismus, the main objective of this study was to assess knowledge and attitudes toward strabismus in Woreta town, Northwest Ethiopia. Providing data in this area is important for planning health policies., Methods: A community-based cross-sectional study was done in Woreta town from April-May 2020 with a sample size of 424. A systematic random sampling technique was employed to achieve the required sample size. A pre-tested self-administered questionnaire was used to collect the data. Data were entered using epi-data version 3.1, then processed and analyzed via SPSS version 20. Descriptive and analytical statistics were employed to summarize the data. A p-value of less than 0.05 was used to declare statistical significance., Result: A total of 401 individuals aged over 18 years participated, with a response rate of 94.5%. Of those who responded, 56.6% were males. Of all the participants, 36.9% were illiterate. The proportion of people with poor knowledge of strabismus was 45.1%. It was shown that 53.9% of the respondents had a favorable attitude. Older age, higher educational level, having a history of eye examination, and a having a family history of strabismus were significantly associated with good knowledge of strabismus. A higher educational level, older age, and hearing about strabismus were significantly associated with a favorable attitude toward strabismus., Conclusion and Recommendation: The proportion of good knowledge and favorable attitude towards strabismus were lower than previously reported in Gondar City, Northwest Ethiopia. There is a need to provide health education and promotion campaigns on strabismus to the community: what strabismus is, its' possible treatments and the need to bring children to the eye care center for early diagnosis and treatment., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2022 Alemayehu et al.

Objective: To describe perioperative practice patterns among retinal surgeons managing retinal detachment (RD) repair., Methods: This was a cross-sectional pilot survey of vitreoretinal surgeons in the United States (US), identified by a previously published web-based search and cross-referencing names from the American Society of Retina Specialists. Self-reported peri-operative practices and subgroups were analyzed., Results: Of the 298 surgical retina specialists who completed the survey, 115 (39%) were in practice for ≤ 5 years, 102 (34%) were in practice for 6 to 20 years, and 81 (27%) were in practice for > 20 years; 60%, 23%, and 16% were in private, academic, and hybrid practice, respectively. Fifty-nine percent reported operating with trainees. For ocular blocks, 59% perform retrobulbar, 21% peribulbar, and 20% subtenon's (ST). Use of ST block varied significantly by years in practice and presence of trainees ( P < 0.0001, P = 0.004, respectively). Sixty percent perform primary scleral buckles (SB), 55% combined SB/pars plana vitrectomy (PPV), and 11% primary PPVs under general anesthesia. Use of general anesthesia for primary SB varied significantly by years in practice ( P = 0.007). Surgeons with fewer years in practice were more likely to recommend facedown positioning for macula-off RDs ( P < 0.0001). Forty-six percent of surgeons do not advise stopping blood thinners before surgery and this varied significantly by years in practice ( P = 0.006)., Conclusions: Variation exists among US vitreoretinal surgeons in relation to anesthesia, postoperative positioning, and blood thinners restrictions. Preferences are influenced by years in practice and less by trainees and practice setting. These results serve as a basis for larger, targeted US-based surveys on perioperative care and correlation with surgical outcomes. [ Ophthalmic Surg Lasers Imaging Retina 2022;53:681-690.] .

Acute appendicitis is a common abdominal surgical emergency worldwide. Abraham Groves performed the first documented open appendectomy in 1883. Although appendectomy is still the most effective treatment in cases of acute appendicitis, it causes a range of complications and carries the risk of negative appendectomy. In the awake of covid-19, the latest guidelines recommend antibiotic therapy as an acceptable first line treatment for acute appendicitis. However, patients treated with antibiotics have a recurrence risk of up to 30% at 1 year. Endoscopic retrograde appendicitis therapy (ERAT) has emerged as promising non-invasive treatment modality for acute uncomplicated appendicitis (AUA) which involves cannulation, appedicography, appendiceal stone extraction, appendiceal lumen irrigation, and stent insertion. ERAT aims to relieve the cause of appendicitis (e.g., obstruction or stenosis of the appendiceal lumen) and thus effectively prevent the recurrence of appendicitis. In addition, it can make a definitive diagnosis of acute appendicitis during endoscopic retrograde appendicography. Studies have shown that 93.8 to 95% of AUA patients did not have a recurrence following ERAT. In this study, we aim to summarize the current body of evidence on ERAT to situate it alongside currently established therapies for acute appendicitis, in particular, AUA., Competing Interests: Declaration of Competing Interest The authors disclose no conflicts., (Copyright © 2022 Elsevier Masson SAS.

Measurement of strength and durability of SARS-COV-2 antibody response is important to understand the waning dynamics of immune response to both vaccines and infection. The study aimed to evaluate the level of IgG antibodies against SARS-CoV-2 and their persistence in recovered, naïve, and vaccinated individuals. We investigated anti-spike RBD IgG antibody responses in 10,000 individuals, both following infection with SARS-CoV-2 and immunization with SARS-COV-2 AstraZeneca, Sputnik V, Sinopharm, and Sinovac. The mean levels of anti-spike IgG antibodies were higher in vaccinated participants with prior COVID-19 than in individuals without prior COVID-19. Overall, antibody titers in recovered vaccinee and naïve vaccinee persisted beyond 20 weeks. Vaccination with adenoviral-vector vaccines (AstraZeneca and Sputnik V) generates higher antibody titers than with killed virus vaccine (Sinopharm and Sinovac). Approximately two-thirds of asymptomatic unvaccinated individuals had developed virus-specific antibodies. A single dose of vaccine is likely to provide greater protection against SARS-CoV-2 infection in individuals with apparent prior SARS-CoV-2 infection, than in SARS-CoV-2-naive individuals. In addition, the high number of seropositivity among asymptomatic unvaccinated individuals showed that the number of infections are probably highly underestimated. Those vaccinated with inactivated vaccine may require more frequent boosters than those vaccinated with adenoviral vaccine. These findings are important for formulating public health vaccination strategies during COVID-19 pandemic.

Objectives: To determine the frequency of vaccination status in patients with SARS-CoV-2 infection., Methods: This case-control study was conducted at Dr Ruth KM Pfau Civil Hospital Karachi, Pakistan between September 2021 to October 2021. All patients who had positive PCR on nasopharyngeal swab for SARS-CoV-2 infection were included. Information regarding vaccination status and brand of vaccination administered and duration between the last dose of vaccine and positive PCR was noted. The disease status of patients was classified on admission into severe and non-severe disease., Results: Study included 143 patients, out of which 58 (40.6%) were males and 85 (59.4%) were females. Majority of our patients (78.3%) were unvaccinated. Frequency of Severe SARS-CoV-2 Infection in fully vaccinated patients was less than in unvaccinated patients. The odds of developing severe COVID infection in unvaccinated patients versus vaccinated was 8.55 times higher (OR = 6.23, 95% CI 2.58-28.35). Proportion of vaccinated females was less as compared to males. Significant differences were found in severity between hypertension (p<.001), diabetes (<.001) and age (p<.001)., Conclusion: The frequency of SARS-CoV-2 infection was greater in unvaccinated patients. The odds of developing severe COVID infection in unvaccinated patients versus vaccinated was 8.55 times higher., Competing Interests: Conflict of Interest: All authors disclose no conflict of interest., (Copyright: © Pakistan Journal of Medical Sciences.)

Traction techniques have emerged as a desirable "second-hand" while performing endoscopic submucosal dissection (ESD), enabling adequate visualization of submucosal tissue and vasculature, which allows for safe and efficient dissection. Multiple traction techniques have been developed over the years, and these can be broadly divided into internal and external traction techniques. This arsenal of techniques allows for traction that is personalized to the location of the lesion undergoing ESD. Mastering traction techniques requires structured training, and understanding of the benefits and pitfalls of each technique. Future research and development efforts need to focus on pathways and curriculums for trainees to master the currently available endoscopic traction techniques and provide avenues for the development of newer traction modalities., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Khan, Ali, Ullah, Huang and Li.)

Purpose: To determine if smartphone photography could be a useful adjunct to blindness prevalence surveys by providing an accurate diagnosis of corneal opacity., Methods: A total of 174 patients with infectious keratitis who had undergone corneal culturing over the past 5 years were enrolled in a diagnostic accuracy study at an eye hospital in South India. Both eyes had an ophthalmologist-performed slit lamp examination, followed by anterior segment photography with a handheld digital single lens reflex (SLR) camera and a smartphone camera coupled to an external attachment that provided magnification and illumination. The diagnostic accuracy of photography was assessed relative to slit lamp examination., Results: In total, 90 of 174 enrolled participants had a corneal opacity in the cultured eye and no opacity in the contralateral eye, and did not have a penetrating keratoplasty or missing photographs. Relative to slit lamp examination, the sensitivity of corneal opacity diagnosis was 68% (95%CI 58-77%) using the smartphone's default settings and 59% (95%CI 49-69%) using the SLR, and the specificity was 97% (95%CI 93-100%) for the smartphone and 97% (95%CI 92-100%) for the SLR. The sensitivity of smartphone-based corneal opacity diagnosis was higher for larger scars (81% for opacities 2 mm in diameter or larger), more visually significant scars (100% for eyes with visual acuity worse than 20/400), and more recent scars (85% for eyes cultured in the past 12 months)., Conclusion: The diagnostic performance of a smartphone coupled to an external attachment, while somewhat variable, demonstrated high specificity and high sensitivity for all but the smallest opacities.

Background: Endoscopic mucosal resection of duodenal polyps (EMR) is a challenging intervention. The aim of this study was to review the patient characteristics, techniques, procedure outcomes, adverse events, and recurrence of duodenal polyps., Research Design and Methods: Patients were included if they had pathologically confirmed non-ampullary duodenal polyps and had received EMR with at least one follow-up EGD for surveillance. Descriptive statistics were employed to report the findings., Results: A total of 65 patients underwent a total of 90 EMRs for duodenal polyps. The mean age was 65.4 years, and 29 of the patients were female. Complete resection of the visible mass was achieved in 96.9% of cases. Endoscopic hemostasis was required in 18.5% of patients. Delayed bleeding occurred in 9%, and delayed perforations requiring surgical intervention occurred in 2.2% of patients with no mortality. Surgery after EMR was needed in 12.7% of cases. Eleven (16.9%) patients had recurrent duodenal adenoma on follow-up EGD., Conclusion: Duodenal polyps can be safely resected and have a notable recurrence rate. This is particularly true for adenomas, warranting post-resection endoscopic surveillance. The appropriate interval for post-resection surveillance of duodenal adenomas should be a focus of future study.

Objectives: To assess frailty in cirrhotic by calculating Liver Frailty Index (LFI) using bedside clinical tests and correlate it with Child-Turcotte-Pugh (CTP), MELD, MELD Na, Fib- 4 and Transient Elastography (TE) scores., Methods: This cross-sectional observational comparative study was carried out in Dr Ruth KM Pfau Civil Hospital, Karachi from August 2020 to September 2021. Patients were subjected to three performance-based testing including dominant hand grip strength (HGS), Chair to Stand (CTS) Time & Three Position Balance (TPB). LFI was calculated using the online LFI calculator, available at http://liverfrailtyindex.ucsf.edu and classified as 'Robust' if LFI <3.2, 'Prefrail' LFI between 3.2 and 4.4, and 'Frail' as LFI ≥4.5. Correlation of frailty with MELD, MELD-Na and CTP Scores was done. Means of MELD & MELD-Na Scores and CTP scores were calculated in all 3 classes of frailty using one way ANOVA. A p -value of ≤.05 was taken as significant., Results: Out of 118 patients, 62 (52.5%) were males. Mean MELD score was 11.4 ±3.3, MELD-Na was 15.97 ±8.54, CTP 8.25 ±2.21, Fib-4 was 2.79 ±1.034 and TE score was 18.20 ±9.17. Mean LFI was 3.87 ±1.07; mean HGS was 18.12 ±4.68; mean of CTS was 9.62 ±3.55. LFI Class distribution in our cohort showed Robust were 36 (30.5%), Prefrail 34 (28.8%) and Frail were 48 (40.8%). Correlation of all these variables with LFI showed significant correlation with LFI, but highest correlation coefficient was seen with MELD-Na., Conclusion: Significant correlation between frailty score in cirrhotic with cirrhosis severity scores highlights the need for frequently assessing LFI in all cirrhotic at regular follow up visits., Competing Interests: Conflict of Interest: All authors state no disclosures for any financial conflict of interest., (Copyright: © Pakistan Journal of Medical Sciences.)

Objectives: To compare the efficacy of Vonoprazan based dual treatment versus PPI based treatment for the eradication of Helicobacter pylori infection., Methods: A randomized controlled trial was conducted in Department of Medicine/Gastroenterology Ruth KM Pfau Civil Hospital, DMC during the period of 22 June to 21 September 2021. Sample size was calculated as 96 in each Group. All patients of age 18-75 years with Helicobacter Pylori Infection were inducted and randomly allocated to two groups. Group-A: were given Capsule Amoxicillin 1 gm; Tablet Clarithromycin 500 mg; Capsule Omeprazole 20 mg all medications were given twice daily for two weeks. Group-B were given Capsule Amoxicillin 1 gm; Tablet Vonoprazan 20 mg (Vonozon © , m/s Getz Pharma, Pakistan) twice daily for two weeks. Confirmation of Hp eradication was done by stool Hp antigen test four weeks after completion of treatment. Nine and four patients were lost to follow-up in Group-A & B respectively. Analysis was conducted on 87 patients in Group-A and 92 patients in Group-B., Results: Out of eighty-seven patients in Group-A and ninety-two patients in Group-B, 73 (83.9%) patients in Group-A and 86 (93.5%) patients in Group-B had negative H pylori result respectively after treatment ( p = .042). Significantly higher frequencies of adverse events were observed in Group-A as compared to Group-B in nausea/vomiting ( p = .035) and bloating ( p = .045)., Conclusion: VA-dual provides an acceptable eradication rate with fewer adverse events., Competing Interests: Conflict of Interest: All authors state no disclosures for any financial conflict of interest., (Copyright: © Pakistan Journal of Medical Sciences.)

Background and Aims: EUS, MRCP, and intraoperative cholangiogram (IOC) are the recommended diagnostic modalities for patients with intermediate probability for choledocholithiasis (IPC). The relative cost-effectiveness of these modalities in patients with cholelithiasis and IPC is understudied., Methods: We developed a decision tree for diagnosing IPC (base-case probability, 50%; range, 10%-70%); patients with a positive test were modeled to undergo therapeutic ERCP. The strategies tested were laparoscopic cholecystectomy with IOC (LC-IOC), MRCP, single-session EUS + ERCP, and separate-session EUS + ERCP. Costs and probabilities were extracted from the published literature. Effectiveness was assessed by assigning utility scores to health states, average proportion of true-positive diagnosis of IPC, and the mean length of stay (LOS) per strategy. Cost-effectiveness was assessed by extrapolating a net-monetary benefit (NMB) and average cost per true-positive diagnosis., Results: LC-IOC was the most cost-effective strategy to diagnose IPC (base-case probability of 50%) among patients with cholelithiasis in health state-based effectiveness analysis (NMB of $34,612), diagnostic test accuracy-based effectiveness analysis (average cost of $13,260 per true-positive diagnosis), and LOS-based effectiveness analysis (mean LOS of 4.13) compared with strategies 2 (MRCP), 3 (single-session EUS + ERCP), and 4 (separate-session EUS + ERCP). These findings were robust on deterministic and probabilistic sensitivity analyses., Conclusions: For patients with cholelithiasis with IPC, LC-IOC is a cost-effective approach that should limit preoperative testing and may shorten hospital LOS. Our findings may be used to design institutional and organizational management protocols., (Copyright © 2022 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

Introduction: We compared the safety and efficacy of Xa-inhibitors to LMWH for treatment of venous thromboembolism in mixed and gastrointestinal cancer cohorts (CA-VTE)., Methods: A systematic search identified RCTs and non-randomized studies (NRS) comparing Xa-inhibitors to LMWH for treating CA-VTE. Relative risks were computed. Certainty was assessed using the GRADE approach., Results: Xa-inhibitors reduced the risk of recurrent VTE (RR0.64;0.49-0.84) and NRS (RR0.74;0.60-0.92;Moderate-Low Certainty). There was no significant difference in recurrent PE in RCTs (RR0.72;0.50-1.02) and NRS (1.43;0.65-3.12;Low-Very Low Certainty). Xa-inhibitors increased the risk of overall bleeding events in RCTs (RR1.45;1.05-2.01) and NRS (RR1.72;1.42-2.08;Moderate-Low Certainty), and the risk of major bleeding events in NRS (RR1.56;1.17-2.07), but not in RCTs (RR1.33;0.94-1.89; Low-Very Low Certainty). Similar results were detected in gastrointestinal cancer patients., Conclusion: Xa-inhibitors may reduce the risk of recurrent VTE, but not recurrent PE compared to LMWH. A higher overall bleeding risk, and a questionably higher major bleeding risk was found with Xa-inhibitor use., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Objectives: This study aimed to validate Baveno-VI recommendations for variceal screening in cACLD in our region and proposed our own cutoff values., Methods: Prospective cross-sectional study was conducted on cACLD patients from August 2020 till April 2021. Patients segregated into Group-A, having Liver stiffness measurement (LSM) of ≥ 20 kPa and platelet of ≤ 150 × 10 9 cells/L; and Group-B having LSM of < 20 kPa and PLT of > 150 × 10 9 cells/L. Gastroscopic findings were segregated into three categories, VNT, Varices Not Needing Treatment (VNNT) and No Varix (NV). ROC plots were generated for LSM and Platelet for VNT for sensitivity, specificity, Negative and Positive Predictive Values were calculated., Results: A total of 134 patients of cACLD were included. Group-A had 72 (53.7%) patients and Group-B had 62 (46.3%) patients. Group-A had 6 (8.3%) NV; 18 (25.0%) VNNT and 48 (66.7%) VNT. Group-B had 26 (41.9%) NV, 24 (38.7%) VNNT and 12 (19.4%) VNT. The sensitivity of 66.7%, specificity of 80.6% and NPV of 67.56% was obtained. Thus 19.4% VNT were missed on following Baveno VI recommendations. ROC in our study suggested cutoff value of 11.5 kPa with sensitivity of 100% and 1-sepcifity pf 78% (AUROC = 0.865; p < .001) of LSM below which screening gastroscopy could be avoided. The positive and negative predicted values for 84.85% and 100% respectively. Cut off value of platelet count for VNNT came out to be ≥ 97.5 × 10 9 cells/L with AUROC 0.891 ( p < .001), having sensitivity of 100 % and 1-specificity of 83.3%., Conclusions: Substantial number of VNT in cACLD patients are missed by following Baveno-VI recommendations and these needs to be revised on regional basis., (Copyright: © Pakistan Journal of Medical Sciences.)

Background: The management of chronic kidney disease (CKD) and its complications places a significant burden on patients, resulting in impairment of their health-related quality of life (HR-QOL). Little is known about treatment-related burden in pre-dialysis and hemodialysis (HD) CKD patients., Objective: This study aimed to investigate the magnitude of treatment-related burden and its impact on HR-QOL among patients with CKD., Methods: This was a prospective, cross-sectional study to assess treatment-related burden and HR-QOL among patients with CKD in Qatar. Treatment-related burden and HR-QOL were assessed quantitatively using the Treatment Burden Questionnaire (TBQ) and the Kidney Disease Quality of Life (KDQOL™) questionnaire, respectively. The total TBQ score ranges from 0 to 150, with a higher score indicating higher treatment burden, while the range of total possible scores for the KDQOL™ are from 0 to 3600 with higher transformed score indicating better QOL. Pre-dialysis and hemodialysis (HD) CKD patients who had regular follow-up appointments at Fahad Bin Jassim Kidney Center in Qatar were enrolled. Data were analyzed descriptively and inferentially using SPSS version-24., Results: Two hundred-eighty CKD patients (HD = 223 and pre-dialysis = 57) were included in the analyses (response rate 60.9%). Approximately 35% of the participants reported moderate to high treatment-related burden (TBQ global score 51-150). HD patients experienced significantly higher treatment burden compared to pre-dialysis patients with a median (IQR) score of 45 (36) versus 25 (33), respectively (p < 0.001). Medication burden and lifestyle changes burden were the highest perceived treatment-related burden. Overall, the perceived median (IQR) HR-QOL measured using the KDQOL-36™ among the participants was 2280.6 (1096.2) compared to the maximum global score of 3600. Similarly, the HD patients demonstrated significantly lower HR-QOL compared to the pre-dialysis patients [median (IQR) score of 2140 (1100) vs. 2930 (995), respectively; p < 0.001). There was a strong negative correlation between TBQ score and KDQOL-36™ score [rs (251) = -0.616, p < 0.001], signifying that HR-QOL decreases as treatment burden increases., Conclusions: This study suggests that a considerable proportion of CKD patients suffered from treatment-related burden and deterioration in HR-QOL at a varying degree of seriousness. HD patients experienced significantly higher burden of treatment and lower HR-QOL compared to pre-dialysis patients and that HR-QOL declines as treatment burden increases. Therefore, treatment-related burden should be considered in CKD management and factors that increase it should be considered when designing healthcare interventions directed to CKD patients., (Copyright © 2021 The Author(s).
