Comprehensive Surgical Audit of Live-Related Donor Nephrectomy: Procedural Parameters, Demographics, Health Assessments, Complications, and Postoperative Outcomes.

BACKGROUND AND OBJECTIVES: End-stage renal disease (ESRD) rates are on the rise globally, including in India. However, the affordability of dialysis treatment remains a significant challenge for many, with costs varying across different regions. Although cost-effective, kidney transplantation faces challenges like a surgeon shortage, lack of infrastructure, and lack of logistic support. The study examines Indian laparoscopic nephrectomy outcomes and their benefits for donor recovery. It covers kidney donor procedural details, demographics, preoperative health evaluations, complications, and one-month follow-up. METHODS: Ethical approval was obtained, and the study involved 102 cases at the Indira Gandhi Institute of Medical Science, Patna, Bihar, India, from 2019 to 2023. Detailed preoperative assessments, postoperative complications, and one-month follow-up analyses were conducted. Statistical analysis employed SPSS version 17 (IBM Corp., Armonk, NY). RESULTS: The results revealed an average surgery time of 152.3 min, blood loss of 205 ± 42 ml, and a hospital stay of 4.6 ± 2.2 days. The study found a female predominance (80.39%), with a mean donor age of 35.9 ± 5.2 years. Preoperative assessments showed robust patient health, with glomerular filtration rate (GFR) exceeding the expected threshold and normal urea levels, creatinine, electrolytes, liver enzymes, bilirubin, albumin, and total protein. Post-nephrectomy complications were reported, with females experiencing more difficulties than males. CONCLUSION: This study underscores the efficiency and safety of laparoscopic nephrectomy in the Indian context, providing valuable insights into donor demographics, preoperative health assessments, complications, and postoperative outcomes. The findings contribute to understanding laparoscopic nephrectomy outcomes and associated risk factors despite certain limitations.

Comparative Study of the Outcome of Buccal Mucosa Graft Urethroplasty and Preputial Flap Urethroplasty for Anterior Urethral Stricture: A Prospective Randomized Study.

BACKGROUND: Urethroplasty using a buccal mucosa graft (BMG) and a preputial skin flap (PSF) are two common techniques used for the treatment of anterior urethral stricture. The present study compared the efficacy of these two techniques on the basis of success rate, preservation of sexual function, and complications. MATERIALS AND METHODS: This prospective, randomized, interventional study was conducted on adult male patients diagnosed with non-obliterative anterior urethral strictures of length >2 cm from August 2021 to December 2022. Pre-operative and post-operative work-up done included assessment of the International Prostate Symptom Score (IPSS), Quality of Life (QOL), International Index of Erectile Function (IIEF) Score, Male Sexual Health Questionnaire for Ejaculatory Dysfunction (MSHQ-EJD), Bother score, Urethral Stricture Surgery-Patient-Related Outcome Measure (USS-PROM), and peak urinary flow rate (Qmax) for each patient. Post-operative values for each score were compared with pre-operative values. RESULTS: Out of 31 patients, 16 underwent BMG urethroplasty, and 15 underwent PSF urethroplasty. The most common cause of stricture in both groups was idiopathic (35.5% and 53.3%). A statistically significant increase in IIEF score was observed in the BMG group in comparison to the PSF group (P<0.0001). The mean IPPS score in USS-PROM has shown a significant drop in BMG (19.6 vs. 17.3; P = 0.020). Hemoglobin drop was significantly higher in PSF than in BMG (2.6 vs. 1.9; P = 0.011). A higher incidence of surgical site infection was reported in the PSF group than in the BMG group (46.7% vs. 12.5%). The average operative time for surgery was higher in PSF than in BMG (154.8 min vs. 145.0 min), respectively. Each group had one patient with a recurrence. CONCLUSION: Both techniques are equally good for urethral reconstruction (UR); however, improvement of sexual function is more in favor of the BMG urethroplasty group.

Higher methadone dose at time of release from prison predicts linkage to maintenance treatment for people with HIV and opioid use disorder transitioning to the community in Malaysia.

BACKGROUND: Incarcerated people with HIV and opioid-dependence often experience poor post-release outcomes in the absence of methadone maintenance treatment (MMT). In a prospective trial, we assessed the impact of methadone dose achieved within prison on linkage to MMT after release. METHODS: From 2010 to 2014, men with HIV (N = 212) and opioid dependence before incarceration were enrolled in MMT within 6 months of release from Malaysia's largest prison and followed for 12-months post-release. As a prospective trial, allocation to MMT was at random and later by preference design (predictive nonetheless). MMT dosing was individually targeted to minimally achieve 80 mg/day. Time-to-event analyses were conducted to model linkage to MMT after release. FINDINGS: Of the 212 participants allocated to MMT, 98 (46 %) were prescribed higher dosages (≥80 mg/day) before release. Linkage to MMT after release occurred in 77 (36 %) participants and significantly higher for those prescribed higher dosages (46% vs 28 %; p = 0.011). Factors associated with higher MMT dosages were being married, on antiretroviral therapy, longer incarceration periods, having higher levels of depression, and methadone preference compared to randomization. After controlling for other variables, being prescribed higher methadone dosage (aHR: 2.53, 95 %CI: 1.42-4.49) was the only independent predictor of linkage to methadone after release. INTERPRETATION: Higher doses of methadone prescribed before release increased the likelihood of linkage to MMT after release. Methadone dosing should be introduced into international guidelines for treatment of opioid use disorder in prisons and further post-release benefits should be explored.

Equity trends for the UHC service coverage sub-index for reproductive, maternal, newborn and child health in Pakistan: evidence from demographic health surveys.

BACKGROUND: Pakistan, the world's sixth most populous country and the second largest in South Asia, is facing challenges related to reproductive, maternal, newborn and child health (RMNCH) that are exacerbated by various inequities. RMNCH coverage indicators such as antenatal care (ANC) and deliveries at health facilities have been improving over time, and the maternal mortality ratio (MMR) is gradually declining but not at the desired rates. Analysing and documenting inequities with reference to key characteristics are useful to unmask the disparities and to amicably implement targeted equity-oriented interventions. METHODS: Pakistan Demographic Health Survey (PDHS) based UHC service coverage tracer indicators were derived for the RMNCH domain at the national and subnational levels for the two rounds of the PDHS in 2012 and 2017. These derivations were subgrouped into wealth quintiles, place of residence, education and mothers' age. Dumbbell charts were created to show the trends and quintile-specific coverage. The UHC service coverage sub-index for RMNCH was constructed to measure the absolute and relative parity indices, such as high to low absolute difference and high to low ratios, to quantify health inequities. The population attributable risk was computed to determine the overall population health improvement that is possible if all regions have the same level of health services as the reference point (national level) across the equity domains. RESULTS: The results indicate an overall improvement in coverage across all indicators over time, but with a higher concentration of data points towards higher coverage among the wealthiest groups, although the poorest quintile continues to have low coverage in all regions. The UHC service coverage sub-index on RMNCH shows that Pakistan has improved from 45 to 63 overall, while Punjab improved from 50 to 59 and Sindh from 43 to 55. The highest improvement is evident in Khyber Pakhtunkhwa (KP) province, which has increased from 31 in 2012 to 51 in 2017. All regions made slow progress in narrowing the gap between the poorest and wealthiest groups, with particularly noteworthy improvements in KP and Sindh, as indicated by the parity ratio. The RMNCH service coverage sub-index gap was the greatest among women aged 15-19 years, those who belonged to the poorest wealth quintile, had no education, and resided in rural areas. CONCLUSIONS: Analysing existing data sources from an equity lens supports evidence-based policies, programs and practices with a focus on disadvantaged subgroups.

Psychosocial risk factors and cognitive decline in people living with HIV: results from the Malaysian HIV and aging (MHIVA) study.

HIV-associated mortality has improved with the advent of antiretroviral therapy, yet neurocognitive decline persists. We assessed the association between psychosocial risk factors and cognitive function among Malaysian PLWH. Data of virally suppressed PLWH (n = 331) on stable ART, from the Malaysian HIV and Aging study was assessed. Psychosocial factors were assessed using the Lubben Social Network Scale-6 (social isolation) and Depression Anxiety Stress Scale-21 (DASS-21). The Montreal Cognitive Assessment (MoCA) with normative standards for the Malaysian population was used to determine cognitive function. Linear and logistic regression were used to assess the associations between cognition, and psychosocial risk factors. Median age of participants was 43.8 years (IQR 37.7-51.0). Participants were predominantly male (82.8%), with secondary education or higher (85.2%). Participants were on ART for 5.7 years (IQR 3.0-9.7), with a mean MoCA score of 24.6 (±3.7). Social isolation was found in 34.6% of participants, and severe depression, severe stress, and severe anxiety in 10.6%, 15.4%, and 6.0% respectively. After adjusting for demographic, clinical, and HIV parameters, MoCA scores were significantly associated with severe stress (ß = -0.11, p = 0.02) and having marginal friendship ties (ß = -0.13, p = 0.03). Social isolation and severe stress are associated with neurocognitive impairment in PLWH.

Mechanical Performance of Glass/Epoxy Composites Loaded with Silane-Treated Aluminum Hydroxide Fillers.

This study investigates the influence of silane-treated aluminum hydroxide on the mechanical performance of flame-retardant composites. These composites have potential applications for luggage bags, as a replacement for conventional plastics, offering more durability and lighter weight. Glass fabric was used as the reinforcement, while epoxy was used as the matrix material. To impart flame retardancy, aluminum hydroxide nanoparticles were used as fillers in different weight % age (5%, 10% and 15%). As these are inorganic particles and have compatibility issues with the matrix material, silane-coupling agents (Dynasylan® 6490 and Dynasylan Glymo) were used to treat these filler particles. Both the silane-coupling agents fraction used for treatment and the fillers fraction added to the composites were varied to determine the most optimum combination. The mechanical properties of the developed composites such as tensile, flexural, and short beam shear strength were investigated. The best results were exhibited by 10% aluminum hydroxide fillers treated with 1% (by weight) coupling agent (Dynasylan Glymo).

Monitoring and evaluating the implementation of essential packages of health services.

Essential packages of health services (EPHS) are a critical tool for achieving universal health coverage, especially in low-income and lower middle-income countries. However, there is a lack of guidance and standards for monitoring and evaluation (M&E) of EPHS implementation. This paper is the final in a series of papers reviewing experiences using evidence from the Disease Control Priorities, third edition publications in EPHS reforms in seven countries. We assess current approaches to EPHS M&E, including case studies of M&E approaches in Ethiopia and Pakistan. We propose a step-by-step process for developing a national EPHS M&E framework. Such a framework would start with a theory of change that links to the specific health system reforms the EPHS is trying to accomplish, including explicit statements about the 'what' and 'for whom' of M&E efforts. Monitoring frameworks need to consider the additional demands that could be placed on weak and already overstretched data systems, and they must ensure that processes are put in place to act quickly on emergent implementation challenges. Evaluation frameworks could learn from the field of implementation science; for example, by adapting the Reach, Effectiveness, Adoption, Implementation and Maintenance framework to policy implementation. While each country will need to develop its own locally relevant M&E indicators, we encourage all countries to include a set of core indicators that are aligned with the Sustainable Development Goal 3 targets and indicators. Our paper concludes with a call to reprioritise M&E more generally and to use the EPHS process as an opportunity for strengthening national health information systems. We call for an international learning network on EPHS M&E to generate new evidence and exchange best practices.

Pakistan's COVID-19 Prevention and Control Response Using the World Health Organization's Guidelines for Epidemic Response Interventions.

Massive coronavirus disease 2019 (COVID-19) devastation was anticipated in Pakistan due to poor track record of responding to epidemics. However, by adopting effective and timely response measures under strong government leadership, Pakistan averted a significant number of infections. We present the government of Pakistan's efforts to curb the spread of COVID-19, using the World Health Organization's guidelines for epidemic response intervention. The sequence of interventions is presented under the epidemic response stages, namely anticipation, early detection, containment-control, and mitigation. Key factors of Pakistan's response included decisive political leadership and implementation of a coordinated and evidence-informed strategy. Moreover, early control measures, mobilization of front-line health workers for contact tracing, public awareness campaigns, 'smart lockdowns', and massive vaccination drives are key strategies that helped flatten the curve. These interventions and lessons learnt can help countries and regions struggling with COVID-19 to develop successful strategies to flatten the curve and enhance disease response preparedness.

An assessment of facility readiness for comprehensive abortion care in 12 districts of Pakistan using the WHO Service Availability and Readiness Assessment tool.

Although Pakistan's Essential Package of Health Services was recently updated to include therapeutic and post-abortion care, little is known about current health facility readiness for these services. This study assessed the availability of comprehensive abortion care, and readiness of health facilities to deliver these services, within the public sector in 12 districts of Pakistan. A facility inventory was completed in 2020-2021 using the WHO Service Availability and Readiness Assessment, with a newly developed abortion module. A composite readiness indicator was developed based on national clinical guidelines and previous studies. Just 8.4% of facilities reported offering therapeutic abortion, while 14.3% offered post-abortion care. Misoprostol (75.2%) was the most common method provided by facilities that offer therapeutic abortion, followed by vacuum aspiration (60.7%) and dilatation and curettage (D&C) (59%). Few facilities had all the readiness components required to deliver pharmacological or surgical therapeutic abortion, or post-abortion care (<1%), but readiness was higher in tertiary (22.2%) facilities. Readiness scores were lowest for "guidelines and personnel" (4.1%), and slightly higher for medicines and products (14.3-17.1%), equipment (16.3%) and laboratory services (7.4%). This assessment highlights the potential to increase the availability of comprehensive abortion care in Pakistan, particularly in primary care and in rural areas, to improve the readiness of health facilities to deliver these services, and to phase out non-recommended methods of abortion (D&C). The study also demonstrates the feasibility and utility of adding an abortion module to routine health facility assessments, which can inform efforts to strengthen sexual and reproductive health and rights.

Image-based cell sorting using focused travelling surface acoustic waves.

Sorting cells is an essential primary step in many biological and clinical applications such as high-throughput drug screening, cancer research and cell transplantation. Cell sorting based on their mechanical properties has long been considered as a promising label-free biomarker that could revolutionize the isolation of cells from heterogeneous populations. Recent advances in microfluidic image-based cell analysis combined with subsequent label-free sorting by on-chip actuators demonstrated the possibility of sorting cells based on their physical properties. However, the high purity of sorting is achieved at the expense of a sorting rate that lags behind the analysis throughput. Furthermore, stable and reliable system operation is an important feature in enabling the sorting of small cell fractions from a concentrated heterogeneous population. Here, we present a label-free cell sorting method, based on the use of focused travelling surface acoustic wave (FTSAW) in combination with real-time deformability cytometry (RT-DC). We demonstrate the flexibility and applicability of the method by sorting distinct blood cell types, cell lines and particles based on different physical parameters. Finally, we present a new strategy to sort cells based on their mechanical properties. Our system enables the sorting of up to 400 particles per s. Sorting is therefore possible at high cell concentrations (up to 36 million per ml) while retaining high purity (>92%) for cells with diverse sizes and mechanical properties moving in a highly viscous buffer. Sorting of small cell fraction from a heterogeneous population prepared by processing of small sample volume (10 µl) is also possible and here demonstrated by the 667-fold enrichment of white blood cells (WBCs) from raw diluted whole blood in a continuous 10-hour sorting experiment. The real-time analysis of multiple parameters together with the high sensitivity and high-throughput of our method thus enables new biological and therapeutic applications in the future.

Material Security Scale as a Measurement of Poverty among Key Populations At-Risk for HIV/AIDS in Malaysia: An Implication for People Who Use Drugs and Transgender People during the COVID-19 Pandemic.

The HIV epidemic is fueled by poverty; yet, methods to measure poverty remain scarce among populations at risk for HIV infection and disease progression to AIDS in Malaysia. Between August and November 2020, using data from a cross-sectional study of people who use drugs, (PWUD), transgender people, sex workers and men who have sex with men, this study examined the reliability and validity of a material security scale as a measurement of poverty. Additionally, we assessed factors associated with material security scores. We performed confirmatory factor analysis (CFA) for 268 study participants included in the analysis. A revised nine-item three-factor structure of the material security scale demonstrated an excellent fit in CFA. The revised material security score displayed good reliability, with Cronbach's alpha of 0.843, 0.826 and 0.818 for housing, economic resources and basic needs factors, respectively. In a subsequent analysis, PWUD and transgender people were less likely to present good material security scores during the pandemic, compared to their counterparts. The revised nine-item scale is a useful tool to assess poverty among key populations at-risk for HIV/AIDS with the potential to be extrapolated in similar income settings.

Understanding changes made to reproductive, maternal, newborn and child health services in Pakistan during the COVID-19 pandemic: a qualitative study.

COVID-19 mitigation measures have disrupted the provision of essential health services. The goal of this study was to understand changes in reproductive, maternal, neonatal, and child health (RMNCH) services during the pandemic in Pakistan. We conducted a qualitative study in November and December 2020 consisting of telephone in-depth interviews with women, healthcare providers, and community stakeholders. Interviews were analysed using a thematic, iterative approach. All health facilities had changed their routine procedures, including adjustments in service delivery time and staff hours to reduce crowding, and maintain standard operating procedures (SOPs) such as social distancing. Women highlighted stockouts and lack of supplies as key barriers to care-seeking. Stockouts and crowding led to shifts in care-seeking away from public to private facilities. RMNCH service utilisation declined first due to restrictions during the lockdown, then due to fear of contracting COVID-19 at healthcare facilities. This study provides important insights into RMNCH services during the COVID-19 pandemic from care-seekers' and care-providers' perspectives. The findings of this study were used to develop interventions to address access to RMNCH care during the COVID-19 pandemic.

Indirect effects of COVID-19 pandemic on reproductive, maternal, newborn and child health services in Pakistan.

Background: COVID-19 is having many impacts on health, economy and social life; some due to the indirect effects of closure of health facilities to curb the spread. Closures were implemented in Pakistan from March 2020, affecting provision of reproductive, maternal, newborn and child health (RMNCH) services. Aims: To appraise the effects of containment and lockdown policies on RMNCH service utilization in order to develop an early response to avoid the catastrophic impact of COVID-19 on RMNCH in Pakistan. Methods: Routine monitoring data were analysed for indicators utilization of RMNCH care. The analysis was based on Period 1 (January-May 2020, first wave of COVID-19); Period 2 (June-September 2020, declining number of cases of COVID-19); and Period 3 (October-December 2020, second wave of COVID-19). We also compared data from May and December 2020 with corresponding months in 2019, to ascertain whether changes were due to COVID-19. Results: Reduced utilization was noted for all RMNCH indicators during Periods 1 and 3. There was a greater decline in service utilization during the first wave, and the highest reduction (~82%) was among children aged < 5 years, who were treated for pneumonia. The number of caesarean sections dropped by 57%, followed by institutional deliveries and first postnatal visit (37% each). Service utilization increased from June to September, but the second wave of COVID-19 led to another decrease. Conclusion: To reinstate routine services, priority actions and key areas include continued provision of family planning services along with uninterrupted immunization campaigns and routine maternal and child services.

COVID-19 seroprevalence in Pakistan: a cross-sectional study.

OBJECTIVES: This study adapted WHO's 'Unity Study' protocol to estimate the population prevalence of antibodies to SARS CoV-2 and risk factors for developing SARS-CoV-2 infection. DESIGN: This population-based, age-stratified cross-sectional study was conducted at the level of households (HH). PARTICIPANTS: All ages and genders were eligible for the study (exclusion criteria: contraindications to venipuncture- however, no such case was encountered). 4998 HH out of 6599 consented (1 individual per HH). The proportion of male and female study participants was similar. PRIMARY AND SECONDARY OUTCOME MEASURES: Following were the measured outcome measures- these were different from the planned indicators (i.e. two out of the three planned indicators were measured) due to operational reasons and time constraints: -Primary indicators: Seroprevalence (population and age specific).Secondary indicators: Population groups most at risk for SARS-CoV-2-infection. RESULTS: Overall seroprevalence of SARS-CoV-2 antibodies was 7.1%. 6.3% of individuals were IgG positive while IgM positivity was 1.9%. Seroprevalence in districts ranged from 0% (Ghotki) to 17% (Gilgit). The seroprevalence among different age groups ranged from 3.9% (0-9 years) to 10.1% (40-59 years). There were no significant differences in the overall seroprevalence for males and females. A history of contact with a confirmed COVID-19 case, urban residence and mask use were key risk factors for developing SARS-CoV-2 infection. CONCLUSIONS: This survey provides useful estimates for seroprevalence in the general population and information on risk factors for developing SARS-CoV-2 infection in the country. It is premised that similar studies need to be replicated at the population level on a regular basis to monitor the disease and immunity patterns related to COVID-19.

Adult-type granulosa cell tumor: An unusual testicular tumor.

Adult type granulosa cell tumours are extremely rare. Albeit mostly benign, 10% have malignant potential associated with unfavorable pathological features. The present case with the longest history duration, shows that size alone may not necessarily be unfavorable prognosticator when not associated with other factors.

Convolutional neural networks with image representation of amino acid sequences for protein function prediction.

Proteins are one of the most important molecules that govern the cellular processes in most of the living organisms. Various functions of the proteins are of paramount importance to understand the basics of life. Several supervised learning approaches are applied in this field to predict the functionality of proteins. In this paper, we propose a convolutional neural network based approach ProtConv to predict the functionality of proteins by converting the amino-acid sequences to a two dimensional image. We have used a protein embedding technique using transfer learning to generate the feature vector. Feature vector is then converted into a square sized single channel image to be fed into a convolutional network. The neural network architecture used here is a combination of convolutional filters and average pooling layers followed by dense fully connected layers to predict a binary function. We have performed experiments on standard benchmark datasets taken from two very important protein function prediction task: proinflammatory cytokines and anticancer peptides. Our experiments show that the proposed method, ProtConv achieves state-of-the-art performances on both of the datasets. All necessary details about implementation with source code and datasets are made available at: https://github.com/swakkhar/ProtConv.

Using Systematized Nomenclature of Medicine clinical term codes to assign histological findings for prostate biopsies in the Gauteng province, South Africa: Lessons learnt.

BACKGROUND: Prostate cancer (PCa) is a leading male neoplasm in South Africa. OBJECTIVE: The aim of our study was to describe PCa using Systemized Nomenclature of Medicine (SNOMED) clinical terms codes, which have the potential to generate more timely data. METHODS: The retrospective study design was used to analyse prostate biopsy data from our laboratories using SNOMED morphology (M) and topography (T) codes where the term 'prostate' was captured in the narrative report. Using M code descriptions, the diagnosis, sub-diagnosis, sub-result and International Classification of Diseases for Oncology (ICD-O-3) codes were assigned using a lookup table. Topography code descriptions identified biopsies of prostatic origin. Lookup tables were prepared using Microsoft Excel and combined with the data extracts using Access. Contingency tables reported M and T codes, diagnosis and sub-diagnosis frequencies. RESULTS: An M and T code was reported for 88% (n = 22 009) of biopsies. Of these, 20 551 (93.37%) were of prostatic origin. A benign diagnosis (ICD-O-3:8000/0) was reported for 10 441 biopsies (50.81%) and 45.26% had a malignant diagnosis (n = 9302). An adenocarcinoma (8140/3) sub-diagnosis was reported for 88.16% of malignant biopsies (n = 8201). An atypia diagnosis was reported for 760 biopsies (3.7%). Inflammation (39.03%) and hyperplasia (20.82%) were the predominant benign sub-diagnoses. CONCLUSION: Our study demonstrated the feasibility of generating PCa data using SNOMED codes from national laboratory data. This highlights the need for extending the results of our study to a national level to deliver timeous monitoring of PCa trends.
