National cervical cancer burden estimation through systematic review and analysis of publicly available data in Pakistan.

BACKGROUND: Cervical cancer is a major cause of cancer-related deaths among women worldwide. Paucity of data on cervical cancer burden in countries like Pakistan hamper requisite resource allocation. OBJECTIVE: To estimate the burden of cervical cancer in Pakistan using available data sources. METHODS: We performed a systematic review to identify relevant data on Pakistan between 1995 to 2022. Study data identified through the systematic review that provided enough information to allow age specific incidence rates and age standardized incidence rates (ASIR) calculations for cervical cancer were merged. Population at risk estimates were derived and adjusted for important variables in the care-seeking pathway. The calculated ASIRs were applied to 2020 population estimates to estimate the number of cervical cancer cases in Pakistan. RESULTS: A total of 13 studies reported ASIRs for cervical cancer for Pakistan. Among the studies selected, the Karachi Cancer Registry reported the highest disease burden estimates for all reported time periods: 1995-1997 ASIR = 6.81, 1998-2002 ASIR = 7.47, and 2017-2019 ASIR = 6.02 per 100,000 women. Using data from Karachi, Punjab and Pakistan Atomic Energy Cancer Registries from 2015-2019, we derived an unadjusted ASIR for cervical cancer of 4.16 per 100,000 women (95% UI 3.28, 5.28). Varying model assumptions produced adjusted ASIRs ranging from 5.2 to 8.4 per 100,000 women. We derived an adjusted ASIR of 7.60, (95% UI 5.98, 10.01) and estimated 6166 (95% UI 4833, 8305) new cases of cervical cancer per year. CONCLUSION: The estimated cervical cancer burden in Pakistan is higher than the WHO target. Estimates are sensitive to health seeking behavior, and appropriate physician diagnostic intervention, factors that are relevant to the case of cervical cancer, a stigmatized disease in a low-lower middle income country setting. These estimates make the case for approaching cervical cancer elimination through a multi-pronged strategy.

Exploring knowledge, attitudes and perceived myths towards foetal programming and factors affecting it among the public and health professionals in Pakistan: a needs assessment study.

OBJECTIVE: To explore knowledge, attitudes and practices of laypersons and health professionals towards foetal programming, and factors affecting it. METHODS: The mixed methods study was conducted at the Aga Khan University, Karachi, from January 20, 2021 to May 13, 2022, and comprised adults of either gender with access to social media platforms. Data was collected using an online survey questionnaire in English and Urdu developed to capture responses from a diverse pool of participants. The survey tool was circulated through WhatsApp, Facebook and Instagram. Two focus group discussions were conducted; one with laypersons in group A and the other with health and allied professionals in group B. Data was analysed using SPSS 21, while data related to focus group discussions was subjected to thematic analysis. RESULTS: Of the 358 participants, 173(48.3%) were in group A and 185(51.7%) were in group B. There were 34(18.4) subjects in group A and 27(15.6) in group B who had knowledge of foetal programming (p>0.05). Only factors related to father's health and dietary elements on the foetus were significantly different between the groups (p<0.05). Thematic analysis led to the formation of 3 overarching themes: parent's lifestyle, comorbidity and diet on foetal health; myths and cultural beliefs regarding foetal development; and the need for training / awareness for practitioners and community. CONCLUSIONS: Lack of knowledge and misinformation about foetal programming and development was common among health professionals and laypersons.

META RNA profiling: Multiplexed quantitation of targeted RNAs across large numbers of samples.

META RNA profiling is a simple and inexpensive method to measure the expression of multiple targeted RNAs across many samples. By assigning sample-specific tags up-front during reverse-transcription, cDNAs from multiple samples can be pooled prior to amplification and deep sequencing. Such early parallelization of samples simplifies the workflow, minimizes cross-sample experimental variability, and reduces reagent and sequencing costs. Herein we describe the theoretical framework of the method and provide a detailed protocol to facilitate its implementation.

Impact of Ebola and COVID-19 on maternal, neonatal, and child health care among populations affected by conflicts: a scoping review exploring demand and supply-side barriers and solutions.

INTRODUCTION: Armed conflicts have a severe impact on the health of women and children. Global health emergencies such as pandemics and disease outbreaks further exacerbate the challenges faced by vulnerable populations in accessing maternal, neonatal, and child healthcare (MNCH). There is a lack of evidence that summarizes the challenges faced by conflict-affected pregnant women, mothers, and children in accessing MNCH services during global health emergencies, mainly the Ebola and COVID-19 pandemics. This scoping review aimed to analyze studies evaluating and addressing barriers to accessing comprehensive MNCH services during Ebola and COVID-19 emergencies in populations affected by conflict. METHODS: The search was conducted on PubMed, Scopus, and Web of Science databases using terms related to Ebola and COVID-19, conflicts, and MNCH. Original studies published between 1990 and 2022 were retrieved. Articles addressing the challenges in accessing MNCH-related services during pandemics in conflict-affected settings were included. Thematic analysis was performed to categorize the findings and identify barriers and solutions. RESULTS: Twenty-nine studies met the inclusion criteria. Challenges were identified in various MNCH domains, including antenatal care, intrapartum care, postnatal care, vaccination, family planning, and the management of childhood illnesses. Ebola-related supply-side challenges mainly concerned accessibility issues, health workforce constraints, and the adoption of stringent protocols. COVID-19 has resulted in barriers related to access to care, challenges pertaining to the health workforce, and new service adoption. On the demand-side, Ebola- and COVID-19-related risks and apprehensions were the leading barriers in accessing MNCH care. Community constraints on utilizing services during Ebola were caused by a lack of trust and awareness. Demand-side challenges of COVID-19 included fear of disease, language barriers, and communication difficulties. Strategies such as partnerships, strengthening of health systems, service innovation, and community-based initiatives have been employed to overcome these barriers. CONCLUSION: Global health emergencies amplify the barriers to accessing MNCH services faced by conflict-affected populations. Cultural, linguistic, and supply-side factors are key challenges affecting various MNCH domains. Community-sensitive initiatives enhancing primary health care (PHC), mobile clinics, or outreach programs, and the integration of MNCH into PHC delivery should be implemented. Efforts should prioritize the well-being and empowerment of vulnerable populations. Addressing these barriers is crucial for achieving universal health coverage and the Sustainable Development Goals.

Extracorporeal Shock Wave Lithotripsy (ESWL) Outcome Based on CT Scan and Patient Parameters Using ESWL Score.

OBJECTIVE: To prospectively evaluate ESWL (extracorporeal shock wave lithotripsy) outcomes and validate ESWL Score. STUDY DESIGN: An observational study. PLACE AND DURATION OF STUDY: The Aga Khan University Hospital, from January 2021 to December 2021. METHODOLOGY: Patients with symptomatic, solitary, radio-opaque renal stone measuring <15 mm with normal renal functions were included in this study. Stone size <11mm, BMI <27 Kg/m2, and stone density <900 Hounsfield units (HU) were all given 1 point each to give a total ESWL Score between 0-3 to each patient. Patients were evaluated after 4-weeks for the outcome i.e. stone clearance and complications. RESULTS: A total of 146 patients were included in the study. Median values for age, stone size, BMI and stone density were 40 years, 8 mm, 27 Kg/m2, and 774 HU respectively. Post ESWL, 99 (68%) patients were stone-free while 47 (32%) patients had residual stones. The stone clearance increased with the increasing score: 50% for ESWL score 0, 55.6% for ESWL score 1, 66.1% for ESWL score 2, and 85.7% for ESWL score 3 (p=0.01). The area under the curve (AUC) of ESWL score was 0.655 with 95 % CI (p=0.001). CONCLUSION: ESWL Score is a useful predictor of the success of ESWL. It can help decide the individualised and appropriate modality of treatment and assist with patient counselling. KEY WORDS: Stone, Lithotripsy, Extracorporeal, Score, Shock wave, Outcome.

A Prospective Evaluation of the Association of Ureteral Wall Thickness With Intraoperative Stone Impaction in Ureteroscopy.

Background and objective In this study, we aimed to analyze the association of ureteral wall thickness (UWT) measured on non-contrast CT (NCCT) with stone impaction as found in ureteroscopy (URS). Materials and methods We analyzed 43 patients who underwent URS and pneumatic/laser lithotripsy for ureteric stones from May to November 2022. The UWT was measured by an experienced radiologist on NCCT. Clinical predictors of the impacted stone were calculated by univariate and multivariate regression analysis. The receiver operating characteristic (ROC) curve was calculated for the UWT cutoff to apply it for impaction with different parameters. We also evaluated the association of intra- and postoperative parameters of the two groups with UWT. Results Out of the 43 patients with stones, 26 (60.46%) patients had impacted stones. Univariate analysis was used to analyze the site (left-sided stone impacted more commonly), stone size, stone density [Hounsfield unit (HU)], hydronephrosis, UWT, and duration between initial presentation and surgery, and multivariate analysis was utilized to assess stone density, as well as UWT's association with impacted stones. The ROC curve showed a cutoff of 3.5 mm for UWT with an accuracy of 0.83. High UWT (≥3.5 mm) was associated with a significantly lower stone-free rate, more complications, and mean operative time as compared to low UWT (<3.5 mm) (p<0.05). Conclusion Based on our findings, high UWT is associated with high rates of impacted stones and a lower stone-free rate when compared to low UWT.

Operating Ethically: A Review of Surgical Ethics in Pakistan and Recommendations for the Way Forward.

Medical ethics underpin the moral framework that delineates the professional relationship between physicians and their patients and thereby is an integral part of making patient-centric healthcare decisions. The concept of ethics is deeply embedded in the field of surgery as surgeons confront a myriad of dilemmas as a part of their routine, whether it be in a preoperative or postoperative environment. The current review aims to describe the state of surgical ethics in Pakistan, with the intent of encouraging dialogues about the ethical considerations relevant to the field surgery that will identify actionable areas for improvement. While most surgeons are aware of the traditional principles of ethics and their practice, their surgical and clinical decisions may fall short of these standards because of time constraints and prevailing cultural and religious beliefs and taboos. The rigorous application of ethical principles in areas of patient-related communication, such as consenting, trainee education, palliative and end-of-life care, and surgical innovation and research, will have significant implications for patients, surgeons, and society. Our review has identified the lack of formal bioethics education and insufficient oversight and ethical regulations to be at the core of inadequate ethical practices in Pakistan and has highlighted actionable areas to be addressed in the future.
