Defining the "Cutoff" on the Urethral Caliber in Diagnosing a Female Urethral Stricture.

Introduction The rarity in detecting female urethral stricture (FUS) backed by the inconsistency regarding the cutoff on the caliber to direct any treatment for its increase poses a challenge to its existence. Therefore, the present study was conducted to determine the caliber of the urethra that clearly identifies a FUS. Materials and method In this prospective observational study conducted between November 2015 and July 2017, women with obstructive lower urinary tract symptoms (LUTS) and a history of relief on at least a single urethral dilatation were included if the American Urological Association (AUA) score was more than seven and the maximum flow rate (Qmax) was less than 20 mL/sec. Of the 71 women recruited, 10 women had recognizable external causes: caruncle (five), mucosal prolapse (three), and meatal stenosis (two). The remaining 61 underwent voiding cystourethrogram (VCUG) and urodynamics followed by urethrocystoscopy, if the findings suggested a stricture. A definitive diagnosis was sought in those without stricture disease. We categorized all patients as either having a "true" stricture or an alternate etiology. Categorical variables were presented in number and percentage (%) and continuous variables as mean ± standard deviation (SD). Results The mean dilatation ranged between one and six; the mean AUA score, ~17.82 ± 3.59; mean Qmax, ~10.21 ± 3.39 mL/sec; and the mean post-void residue (PVR), 106.65 ± 51 mL. A total of 29 patients were diagnosed to have stricture (dense = 17; flimsy = 12). None of the patients in this group had a urethral caliber of more than 14 French (Fr). Other etiologies were dysfunctional voiding (17), underactive bladder (seven), cystocele (four), and primary bladder neck obstruction (PBNO) (four). Conclusion Women with voiding LUTS should be screened for FUS only if the urethral caliber is ≤14 Fr.

Deaths among Women of Reproductive Age: an Explorative Case Study among Abortion Seekers.

In Nepal, abortion was legalized in 2002. Yet many women are denied abortion services. Women denied abortion services may either continue their pregnancies or find abortion care elsewhere. However, what is not known is the consequences on women, and their children after accessing abortion services or after being denied abortion services. This comment aims to understand the cause of death of women who sought abortion services between 2019 and 2020 and were enrolled in a longitudinal nationwide study of the consequences of legal abortion access in Nepal. Women were interviewed 6 weeks and every 6 months for 3 years after seeking abortion. During the follow-up interviews, the field research assistants were informed about the death of the clients. Once the death was reported, a trained senior research staff visited the deceased persons house and interviewed family members including husbands, maternal parents or in-laws to explore the cause of death. A total of nine deaths were reported between April 2019 and December 2022. Out of nine deceased women, four received abortions while five of them were initially denial abortion services. The majority of the deaths were due to suicide followed by tuberculosis. None of the deaths were caused by abortion or birth. Keywords: Death; Nepal; reproductive ages; womens health.

Utilization of Lipophilic Salt and Phospholipid Complex in Lipid-Based Formulations to Modulate Drug Loading and Oral Bioavailability of Pazopanib.

Pazopanib hydrochloride (PAZ) displays strong intermolecular interaction in its crystal lattice structure, limiting its solubility and dissolution. The development of lipid-based formulations (LbFs) resulted in reduced PAZ loading due to solid-state mediated low liposolubility. This study aims to enhance our understanding of PAZ crystallinity by synthesizing a lipophilic salt and phospholipid complex and investigating its impact on the drug loading in LbFs. The synthesized pazopanib lipophilic salt and phospholipid complex were extensively characterized. The solid form of pazopanib docusate (PAZ-DOC) and pazopanib phospholipid complex (PAZ-PLC) indicates a reduction in characteristic diffraction peaks of crystalline PAZ. The lipid formulations were prepared using synthesized PAZ-DOC and PAZ-PLC, where PAZ-DOC demonstrated six fold higher drug solubility than the commercial salt form and twice that of the PAZ-PLC due to differences in the crystallinity. Further, the impact of salt and complex formation was assessed on the aqueous drug solubilization using lipolysis and multimedia dissolution experiments. Moreover, the LbFs showed notably faster dissolution compared to the crystalline PAZ and marketed tablet. In terms of in vivo pharmacokinetics, the PAZ-DOC LbF exhibited a remarkable 11-fold increase in AUC value compared to the crystalline PAZ and a 2.5-fold increase compared to Votrient®. Similarly, PAZ-PLC LbF showed an approximately nine fold increase in drug exposure compared to the crystalline PAZ, and a 2.2-fold increase compared to Votrient®. These findings suggest that disrupting the crystallinity of drugs and incorporating them into LbF could be advantageous for enhancing drug loading and overcoming limitations related to drug absorption.

Blood lead levels in pregnant women and their newborn infants at an Indian teaching hospital.

Background and Aim: With the growth of the world's economy and industrialization, lead (Pb) contamination in the environment has become a major issue on a global scale. Lead is typically linked to unfavorable pregnancy outcomes such as stillbirth, low birth weight preterm, and spontaneous abortion. In this study, we evaluated the blood lead levels of pregnant women and their birth outcomes attending an Indian tertiary care teaching hospital, those who were not exposed to any lead-associated industry or shops. Methods: A descriptive study was undertaken to evaluate blood lead estimation in pregnant women and umbilical blood lead levels in a community hospital. Blood samples from 104 mothers during the 1st trimester, 90 mothers during 3rd trimester, and from the umbilical cord were collected. Self-administered questionnaires were used to collect information on demographics, medical history, and concerns linked to pregnancy. Following acid digestion, the levels of lead in whole blood were determined by an atomic absorption spectrometer. The DNA damage in high blood lead-concentrated pregnant women was evaluated by comet assay methods. Results: Among 194 blood samples of pregnant women, 31 (15.98%) samples revealed ≥5 µg/dL blood lead levels. High lead concentration (≥5 µg/dL) in 1st trimester pregnant women, end of 3rd trimester and cord blood were detected 20.19%, 11.11% and 1.11% respectively. The mean blood lead levels in 1st trimester, 3rd trimester, and cord blood were 3.88 ± 3.19, 2.66 ± 1.82, and 1.53 ± 1.06 mg/dL, respectively. The blood lead concentrations were significantly higher in the 1st trimester of pregnancy than in the 3rd trimester of pregnancy (P < 0.0017). A positive correlation between maternal and infant blood lead levels was revealed (P < 0.0001). When the comet assay was used to assess the genotoxic consequences of elevated blood lead levels during pregnancy, higher amounts of DNA damage were found in the samples (P < 0.01). Conclusion: In this descriptive study, there was a significant amount of lead transferred from mother to baby through the placenta. All mothers were not exposed to lead-associated industry and most were housewives. This article may be viewed as an eye-opener for understanding the blood lead concentration during pregnancy to avoid abnormal birth outcomes. To minimize exposure to environmental lead, all possible measures should be undertaken.

The Role of Osteogenic Effect and Vascular Function in Bone Health in Hypertensive Rats: A Study of Anti-hypertensive and Hemorheologic Drugs.

Vascular dysfunction contributes to the development of osteopenia in hypertensive patients, as decreased blood supply to bones results in tissue damage and dysfunction. The effect of anti-hypertensive medicines on bone mass in hypertensive individuals is inconclusive because of the varied mechanism of their action, and suggests that reducing blood pressure (BP) alone is insufficient to enhance bone mass in hypertension. Pentoxifylline (PTX), a hemorheological drug, improves blood flow by reducing blood viscosity and angiogenesis, also has an osteogenic effect. We hypothesized that improving vascular function is critical to increasing bone mass in hypertension. To test this, we screened various anti-hypertensive drugs for their in vitro osteogenic effect, from which timolol and hydralazine were selected. In adult female spontaneously hypertensive rats (SHRs), timolol and hydralazine did not improve vascular function and bone mass, but PTX improved both. In female SHR animals, PTX restored bone mass, strength and mineralization, up to the level of normotensive control rats. In addition, we observed lower blood vasculature in the femur of adult SHR animals, and PTX restored them. PTX also restored the bone vascular and angiogenesis parameters that had been impaired in OVX SHR compared to sham SHR. This study demonstrates the importance of vascular function in addition to increased bone mass for improving bone health as achieved by PTX without affecting BP, and suggests a promising treatment option for osteoporosis in hypertensive patients, particularly at-risk postmenopausal women.

Numerical simulation of the blood flow through a pre-stenotic aneurysm in coronary artery: effects of varying heart rate.

The left anterior descending artery (LAD) is a significant coronary artery and a facilitator of oxygenated blood to the heart muscles. Thus, any occurrence of an aneurysm in LAD requires immediate medical attention. It is often inclined toward fatality if coupled with a blockage due to stenosis. Given the high relevance of understanding such models, invasive techniques under all parametric circumstances are hard to achieve. So, a theoretical approach with a cost-effective intervention of mathematical modeling becomes essential. In our current work, we analyze the model with the numerical technique of a modified form of SIMPLE pressure-correction based algorithm and perform parametric studies for the flow field with degree of stenosis, degree of aneurysm, heart rate, and distance separating aneurysm and stenosis as parameters. The study reveals a direct proportionality relation between the number of recirculation zones and heart rate through instantaneous streamline plots. Alongside this, the demonstration of an increase in the risk of rupture of the aneurysm with a decrease in the distance between stenosis and aneurysm, using the physical parameters associated with blood flow, is another key finding. Further, we examine the effect of the flow field on heat transfer and the consequent temperature profiles.

Meta-QTL analysis in wheat: progress, challenges and opportunities.

Wheat, an important cereal crop globally, faces major challenges due to increasing global population and changing climates. The production and productivity are challenged by several biotic and abiotic stresses. There is also a pressing demand to enhance grain yield and quality/nutrition to ensure global food and nutritional security. To address these multifaceted concerns, researchers have conducted numerous meta-QTL (MQTL) studies in wheat, resulting in the identification of candidate genes that govern these complex quantitative traits. MQTL analysis has successfully unraveled the complex genetic architecture of polygenic quantitative traits in wheat. Candidate genes associated with stress adaptation have been pinpointed for abiotic and biotic traits, facilitating targeted breeding efforts to enhance stress tolerance. Furthermore, high-confidence candidate genes (CGs) and flanking markers to MQTLs will help in marker-assisted breeding programs aimed at enhancing stress tolerance, yield, quality and nutrition. Functional analysis of these CGs can enhance our understanding of intricate trait-related genetics. The discovery of orthologous MQTLs shared between wheat and other crops sheds light on common evolutionary pathways governing these traits. Breeders can leverage the most promising MQTLs and CGs associated with multiple traits to develop superior next-generation wheat cultivars with improved trait performance. This review provides a comprehensive overview of MQTL analysis in wheat, highlighting progress, challenges, validation methods and future opportunities in wheat genetics and breeding, contributing to global food security and sustainable agriculture.

Population structure and genetic differentiation analyses reveal high level of diversity and allelic richness in crop wild relatives of AA genome species of rice (Oryza sativa L.) in India.

Crop wild relatives (CWRs) are vital sources of variation for genetic improvement, but their populations are few in genebanks, eroded in natural habitats and inadequately characterized. With a view to explore genetic diversity in CWRs of AA genome rice (Oryza sativa L.) species in India, we analyzed 96 accessions of 10 Oryza species by using 17 quantitative traits and 45 microsatellite markers. The morpho-quantitative traits revealed a high extent of phenotypic variation in the germplasm. Diversity index (H') revealed a high level of within-species variability in O. nivara (H' = 1.09) and O. rufipogon (H' = 1.12). Principal component (PC) analysis explained 79.22% variance with five PCs. Among the traits related to phenology, morphology, and yield, days to heading showed strong positive association with days to 50% flowering (r = 0.99). However, filled grains per panicle revealed positive association with spikelet fertility (0.71) but negative with awn length (- 0.58) and panicle bearing tillers (- 0.39). Cluster analysis grouped all the accessions into three major clusters. Microsatellite analysis revealed 676 alleles with 15.02 alleles per locus. High polymorphism information content (PIC = 0.83) and Shannon's information index (I = 2.31) indicated a high level of genetic variation in the CWRs. Structure analysis revealed four subpopulations; first and second subpopulations comprised only of O. nivara accessions, while the third subpopulation included both O. nivara and O. rufipogon accessions. Population statistics revealed a moderate level of genetic differentiation (FST = 0.14), high gene diversity (HE = 0.87), and high gene flow (Nm = 1.53) among the subpopulations. We found a high level of molecular variance among the genotypes (70%) and low among populations (11%) and within genotypes (19%). The high level of molecular and morphological variability detected in the germplasm of CWRs could be utilized for the improvement of cultivated rice.

The Effect of Salivary Contamination on the Shear Bond Strength of Seventh- and Eighth-generation Adhesive Systems.

Aim: To compare the effect of salivary contamination on the shear bond strength (SBS) of seventh- and eighth-generation adhesives. Materials and methods: Specimens were randomly divided into group I and group II, subdivided into three subgroups of 11 samples. Subgroup IA-seventh-generation uncontaminated (control); adhesive; air-dried; light cured. Subgroup IB-seventh-generation adhesive; saliva application, air-dried; light cured. Subgroup IC-seventh-generation adhesive; saliva application, air-dried, reapplication of adhesive, air-dried, light cured. Subgroup IIA- eighth-generation uncontaminated (control); adhesive, air-dried; light cured. Subgroup IIB- eighth-generation adhesive; saliva application, air-dried; light cured. Subgroup IIC-eighth-generation adhesive, saliva application, air-dried, reapplication of adhesive, air-dried; light cured. Following bonding procedure, composite resin restoration was done and subjected to SBS analysis. Results: Mean SBS of eighth-generation adhesive was higher compared to seventh with and without saliva contamination. Reduction of SBS in seventh- and eighth-generation after saliva contamination was regained by reapplication of adhesive, which was less compared to the control [statistically significant (p < 0.05) for seventh and statistically not significant for eighth-generations]. Conclusion: The eighth-generation adhesives show better SBS with and without saliva contamination and reapplication of eighth-generation adhesives significantly improved the SBS close to the control. Clinical significance: Single-step self-etch adhesives are the adhesives which are currently used for bonding composite restorations to dentin. The adhesive bond strength can be adversely affected by moisture contamination, especially by saliva, which can lead to failure of restoration. So, it is imperative to study a material which gives better bond strength and is less affected by salivary contamination and effect of decontamination to regain the bond strength. The study concluded that eighth-generation adhesives showed higher mean SBS with and without saliva contamination and reapplication of eighth-generation adhesives significantly improved the bond strength close to the control group.

Identification of Climate-Smart Bread Wheat Germplasm Lines with Enhanced Adaptation to Global Warming.

Bread wheat (Triticum aestivum L.) is widely grown in sub-tropical and tropical areas and, as such, it is exposed to heatstress especially during the grain filling period (GFP). Global warming has further affected its production and productivity in these heat-stressed environments. We examined the effects of heatstress on 18 morpho-physiological and yield-related traits in 96 bread wheat accessions. Heat stress decreased crop growth and GFP, and consequently reduced morphological and yield-related traits in the delayed sown crop. A low heat susceptibility index and high yield stability were used for selecting tolerant accessions. Under heatstress, the days to 50% anthesis, flag-leaf area, chlorophyll content, normalized difference vegetation index (NDVI), thousand grain weight (TGW), harvest index and grain yield were significantly reduced both in tolerant and susceptible accessions. The reduction was severe in susceptible accessions (48.2% grain yield reduction in IC277741). The plant height, peduncle length and spike length showeda significant reduction in susceptible accessions, but a non-significant reduction in the tolerant accessions under the heatstress. The physiological traits like the canopy temperature depression (CTD), plant waxiness and leaf rolling were increased in tolerant accessions under heatstress. Scanning electron microscopy of matured wheat grains revealed ultrastructural changes in endosperm and aleurone cells due to heat stress. The reduction in size and density of large starch granules is the major cause of the yield and TGW decrease in the heat-stress-susceptible accessions. The most stable and high-yielding accessions, namely, IC566223, IC128454, IC335792, EC576707, IC535176, IC529207, IC446713 and IC416019 were identified as the climate-smart germplasm lines. We selected germplasm lines possessing desirable traits as potential parents for the development of bi-parent and multi-parent mapping populations.

Effect of yeast on functional and rheological characteristics of whole wheat flour and its effect on quality of chapati.

Chapati is unleavened flat bread originated from Indian sub-continent and is considered as staple product in everyday meals. Its quality attributes are dependent on number of factors including the wheat used, ingredients added and processing parameters. The study was aimed to observe the effect of yeast addition on functional, rheological, and sensory characteristics on whole wheat flour and chapati at varying percentage (0.25-1.0). All the experiments conducted were compared with a control flour/chapati without yeast addition. The results showed that all the attributes were favourably affected with yeast addition when compared with control samples. It was noticed that the peak viscosity, setback, breakdown and final viscosity decreased with yeast addition and the paste obtained had higher gel strength. Alveogragh results also depict the increase in tensile strength and decrease in extensibility of dough on yeast incorporation. Textural and sensory studies revealed that yeast concentration upto 0.75% w/w in whole wheat flour resulted in chapati with good overall acceptability.

Association mapping reveals novel genes and genomic regions controlling grain size architecture in mini core accessions of Indian National Genebank wheat germplasm collection.

Wheat (Triticum aestivum L.) is a staple food crop for the global human population, and thus wheat breeders are consistently working to enhance its yield worldwide. In this study, we utilized a sub-set of Indian wheat mini core germplasm to underpin the genetic architecture for seed shape-associated traits. The wheat mini core subset (125 accessions) was genotyped using 35K SNP array and evaluated for grain shape traits such as grain length (GL), grain width (GW), grain length, width ratio (GLWR), and thousand grain weight (TGW) across the seven different environments (E1, E2, E3, E4, E5, E5, E6, and E7). Marker-trait associations were determined using a multi-locus random-SNP-effect Mixed Linear Model (mrMLM) program. A total of 160 non-redundant quantitative trait nucleotides (QTNs) were identified for four grain shape traits using two or more GWAS models. Among these 160 QTNs, 27, 36, 38, and 35 QTNs were associated for GL, GW, GLWR, and TGW respectively while 24 QTNs were associated with more than one trait. Of these 160 QTNs, 73 were detected in two or more environments and were considered reliable QTLs for the respective traits. A total of 135 associated QTNs were annotated and located within the genes, including ABC transporter, Cytochrome450, Thioredoxin_M-type, and hypothetical proteins. Furthermore, the expression pattern of annotated QTNs demonstrated that only 122 were differentially expressed, suggesting these could potentially be related to seed development. The genomic regions/candidate genes for grain size traits identified in the present study represent valuable genomic resources that can potentially be utilized in the markers-assisted breeding programs to develop high-yielding varieties.

A novel breakthrough in wrist-worn transdermal troponin-I-sensor assessment for acute myocardial infarction.

Aims: Clinical differentiation of acute myocardial infarction (MI) from unstable angina and other presentations mimicking acute coronary syndromes (ACS) is critical for implementing time-sensitive interventions and optimizing outcomes. However, the diagnostic steps are dependent on blood draws and laboratory turnaround times. We tested the clinical feasibility of a wrist-worn transdermal infrared spectrophotometric sensor (transdermal-ISS) in clinical practice and assessed the performance of a machine learning algorithm for identifying elevated high-sensitivity cardiac troponin-I (hs-cTnI) levels in patients hospitalized with ACS. Methods and results: We enrolled 238 patients hospitalized with ACS at five sites. The final diagnosis of MI (with or without ST elevation) and unstable angina was adjudicated using electrocardiography (ECG), cardiac troponin (cTn) test, echocardiography (regional wall motion abnormality), or coronary angiography. A transdermal-ISS-derived deep learning model was trained (three sites) and externally validated with hs-cTnI (one site) and echocardiography and angiography (two sites), respectively. The transdermal-ISS model predicted elevated hs-cTnI levels with areas under the receiver operator characteristics of 0.90 [95% confidence interval (CI), 0.84-0.94; sensitivity, 0.86; and specificity, 0.82] and 0.92 (95% CI, 0.80-0.98; sensitivity, 0.94; and specificity, 0.64), for internal and external validation cohorts, respectively. In addition, the model predictions were associated with regional wall motion abnormalities [odds ratio (OR), 3.37; CI, 1.02-11.15; P = 0.046] and significant coronary stenosis (OR, 4.69; CI, 1.27-17.26; P = 0.019). Conclusion: A wrist-worn transdermal-ISS is clinically feasible for rapid, bloodless prediction of elevated hs-cTnI levels in real-world settings. It may have a role in establishing a point-of-care biomarker diagnosis of MI and impact triaging patients with suspected ACS.

Developing the menstrual justice agenda: insights from a mixed method study in the mid-western region of Nepal.

This article develops the concept of "menstrual justice". The legal scholar Margaret E. Johnson has developed an expansive approach to menstrual justice incorporating rights, justice, and a framework for intersectional analysis, with a focus on the US. This framework provides a welcome alternative to the constrictive and medicalised approaches often taken towards menstruation. However, the framework is silent on several issues pertaining to menstruation in Global South contexts. This article therefore develops the concept of menstrual justice in order to extend its relevance beyond the Global North. It presents the findings of mixed-methods research conducted in April 2019 in the mid-western region of Nepal, particularly concerning the practice of chhaupadi, an extreme form of menstrual restriction. We conducted a quantitative survey of 400 adolescent girls and eight focus group discussions, four with adolescent girls and four with adult women. Our findings confirm that dignity in menstruation requires addressing pain management, security issues, and mental health, plus structural issues including economic disadvantage, environmental issues, criminal law, and education.

Impact of Sumadhur intervention on fertility and family planning decision-making norms: a mixed methods study.

BACKGROUND: Mindful of social norms shaping health among women pressured to prove early fertility in Nepal, a bi-national research team developed and piloted a 4-month intervention engaging household triads (newly married women, their husbands, and mothers-in-law) toward advancing gender equity, personal agency, and reproductive health. This study evaluates the impact on family planning and fertility decision-making. METHODS: In 2021, Sumadhur was piloted in six villages with 30 household triads (90 participants). Pre/post surveys of all participants were analyzed using paired sample nonparametric tests and in-depth interviews with a subset of 45 participants were transcribed and analyzed thematically. RESULTS: Sumadhur significantly impacted (p < .05) norms related to pregnancy spacing and timing, and sex preference of children, as well as knowledge about family planning benefits, pregnancy prevention methods, and abortion legality. Family planning intent also increased among newly married women. Qualitative findings revealed improved family dynamics and gender equity, and shed light on remaining challenges. CONCLUSIONS: Entrenched social norms surrounding fertility and family planning contrasted with participants' personal beliefs, highlighting needed community-level shifts to improve reproductive health in Nepal. Engagement of influential community- and family-members is key to improving norms and reproductive health. Additionally, promising interventions such as Sumadhur should be scaled up and reassessed.

Societal norms are among the key influencers that shape the decisions that people make about their desired family size and the methods they will apply to achieve it. To support women in Nepal, where norms are often layered upon the expectation that women will prove their fertility soon after marriage, a bi-national research team developed and piloted a 4-month intervention, Sumadhur, engaging newly married women, their husbands, and mothers-in-law. This study evaluated the impact the Sumadhur had on norms, knowledge, and intent related to family planning. From pre- and post-questionnaires, we found norms significantly shifted and knowledge significantly improved among all participant groups as a result of participating in Sumadhur. From interviews following the intervention, we found that family dynamics and gender equity also improved despite lingering challenges including unchanged norms about the expected timing of a couple's first child. Our results confirmed that it is critical to engage influential community and family members in improving norms and supporting women to make decisions about their reproduction. Additionally, promising interventions like Sumadhur should be scaled up and re-evaluated.

Digital dashboards with paradata can improve data quality where disease surveillance relies on real-time data collection.

Dealing with the threats of vector-borne diseases necessitates robust disease surveillance systems. The gathered information from surveillance studies is used to evaluate the effectiveness of control measures. It also guides the allocation of resources within the healthcare system. The disease surveillance data also identify high-risk populations or geographic areas to target interventions. Because of the importance of surveillance in decision-making and its timely requirement, real-time data collection is vital. A few advantages of real-time data collection apps are building powerful digital forms, exporting data for quick analysis in various formats, and being open-source. These apps automate data collection and transfer to an online server even without an internet connection. While collecting disease surveillance data digitally one crucial aspect lacking is data quality. This paper aims to present the importance of dashboards that includes paradata in improving data quality using real-time data collection tools in disease surveillance. Various types of paradata such as timestamps, geo-referencing, audio recording and so on help enhance the quality of data and can help monitor and evaluate surveillance staff. The outcomes of the paradata analysis may lead to the retraining of the surveillance team and even re-planning of surveillance. Undoubtedly, real-time data collection is the way of the future in any field-based study, and studies should be planned in conjunction with paradata to ensure that high-quality data are recorded.

Intimate partner violence, food insecurity and COVID-19 among newly married women in Nawalparasi district of Nepal: a longitudinal study.

This paper examines factors associated with intimate partner violence (IPV) among newly married women in Nepal, and how IPV was affected by food insecurity and COVID-19. Given evidence that food insecurity is associated with IPV and COVID-19, we explored whether increased food insecurity during COVID-19 is associated with changes in IPV. We used data from a cohort study of 200 newly married women aged 18-25 years, interviewed five times over two years at 6-month intervals (02/2018-07/2020), including after COVID-19-associated lockdowns. Bivariate analysis and mixed-effects logistic regression models were used to examine the association between selected risk factors and recent IPV. IPV increased from 24.5% at baseline to 49.2% before COVID-19 and to 80.4% after COVID-19. After adjusting for covariates, we find that both COVID-19 (OR = 2.93, 95% CI 1.07-8.02) and food insecurity (OR = 7.12, 95% CI 4.04-12.56) are associated with increased odds of IPV, and IPV increased more for food-insecure women post COVID-19 (compared to non-food insecure), but this was not statistically significant (confidence interval 0.76-8.69, p-value = 0.131). Young, newly married women experience high rates of IPV that increase with time in marriage, and COVID-19 has exacerbated this, especially for food-insecure women in the present sample. Along with enforcement of laws against IPV, our results suggest that special attention needs to be paid to women during a crisis time like the current COVID-19 pandemic, especially those who experience other household stressors.

Denial of legal abortion in Nepal.

INTRODUCTION: In Nepal, abortion is legal on request through 12 weeks of pregnancy and up to 28 weeks for health and other reasons. Abortion is available at public facilities at no cost and by trained private providers. Yet, over half of abortions are provided outside this legal system. We sought to investigate the extent to which patients are denied an abortion at clinics legally able to provide services and factors associated with presenting late for care, being denied, and receiving an abortion after being denied. METHODS: We used data from a prospective longitudinal study with 1835 women aged 15-45. Between April 2019 and December 2020, we recruited 1,835 women seeking abortions at 22 sites across Nepal, including those seeking care at any gestational age (n = 537) and then only those seeking care at or after 10 weeks of gestation or do not know their gestational age (n = 1,298). We conducted interviewer-led surveys with these women at the time they were seeking abortion service (n = 1,835), at six weeks after abortion-seeking (n = 1523) and six-month intervals for three years. Using descriptive and multivariable logistic regression models, we examined factors associated with presenting for abortion before versus after 10 weeks gestation, with receiving versus being denied an abortion, and with continuing the pregnancy after being denied care. We also described reasons for the denial of care and how and where participants sought abortion care subsequent to being denied. Mixed-effects models was used to accounting clustering effect at the facility level. RESULTS: Among those recruited when eligibility included seeking abortion at any gestational age, four in ten women sought abortion care beyond 10 weeks or did not know their gestation and just over one in ten was denied care. Of the full sample, 73% were at or beyond 10 weeks gestation, 44% were denied care, and 60% of those denied continued to seek care after denial. Nearly three-quarters of those denied care were legally eligible for abortion, based on their gestation and pre-existing conditions. Women with lower socioeconomic status, including those who were younger, less educated, and less wealthy, were more likely to present later for abortion, more likely to be turned away, and more likely to continue the pregnancy after denial of care. CONCLUSION: Denial of legal abortion care in Nepal is common, particularly among those with fewer resources. The majority of those denied in the sample should have been able to obtain care according to Nepal's abortion law. Abortion denial could have significant potential implications for the health and well-being of women and their families in Nepal.

Use of Critical View of Safety and Proctored Preceptorship in Preventing Bile Duct Injury During Laparoscopic Cholecystectomy-Experience of 3726 Cases From a Tertiary Care Teaching Institute.

INTRODUCTION: Bile duct injury (BDI) continues to occur despite technological advances and improvements in surgical training over the past 2 decades. This study was conducted to audit our data on laparoscopic cholecystectomies performed over the past 2 decades to determine the role of Critical View of Safety (CVS) and proctored preceptorship in preventing BDI and postoperative complications. MATERIALS AND METHODS: All patients undergoing elective laparoscopic cholecystectomy were analyzed retrospectively. The data were obtained from a prospectively maintained database from January 2004 to December 2019. Proctored preceptorship was used in all cases. Intraoperative details included the number of patients where CVS was defined, number of BDI and conversions. Postoperative outcomes, including hospital stay, morbidity, and bile duct stricture, were noted. RESULTS: Three thousand seven hundred twenty-six patients were included in the final analysis. Trainee surgeons performed 31.6% of surgeries and 9.5% of these surgeries were taken over by the senior surgeon. A CVS could be delineated in 96.6% of patients. The major BDI rate was only 0.05%. CONCLUSION: This study reiterates the fact that following the basic tenets of safe laparoscopic cholecystectomy, defining and confirming CVS, and following proctored preceptorship are critical in preventing major BDI.

A comparative analysis of trans-abdominal pre-peritoneal repair in uncomplicated vs complicated inguinal hernia repair.

INTRODUCTION: Trans-abdominal pre-peritoneal (TAPP) repair is one of the standard techniques for laparoscopic repair of groin hernias. Literature has shown that both total extraperitoneal (TEP) and TAPP are equally effective with similar outcomes but TAPP has an advantage over TEP as there is more working space, and it provides access to the opposite side for repair of occult hernias. We reviewed our experience of TAPP repair in complicated groin hernias and compared the outcomes with uncomplicated groin hernia. METHODS: Patients undergoing TAPP repair from January 2004 to December 2019 were analyzed, and divided into two groups-I uncomplicated and II complicated groin hernia. RESULTS: TAPP repair was performed in 820 patients, of which 70.3% had uncomplicated and 29.7% patients had complicated hernias. Occult hernia was detected in 61 patients. The intra-operative complications (16.8% vs 1.3%) and conversions (2.4%) were higher in complicated hernias. Laparoscopic assisted repair was used in 16.8% patients with complicated hernias. The incidence of post-operative complications (62.1% vs 17.3%; P value <.01) were significantly higher in complicated groin hernia patients. The median follow-up was 15 months; only three patients in the uncomplicated hernia group developed recurrence, and chronic groin pain was higher in the complicated hernia repair patients (P > .05) at 6 months. CONCLUSION: Although operative time, incidence of intra-operative and post-operative complications (albeit minor in nature), and conversions to open are higher after TAPP repair for complicated groin hernias, the short-term outcomes (hematoma, mesh infection) as well as long-term outcomes (chronic groin pain, port site hernia and recurrence) are not different when compared with uncomplicated hernias. TAPP repair can be used in both complicated and uncomplicated groin hernias with similar short-term and long-term outcomes, albeit with a slightly higher incidence of minor complications in complicated hernias. This can be taken into consideration while operating on patients with complicated hernias and taking informed consent.
