Outcome of Vaginal Hysterectomy versus Abdominal Hysterectomy for Benign Non-Prolapsed Uterus

Introduction: Hysterectomy is a very frequent pregnancy-unrelated surgical procedure performed in women, which may be accomplished either by abdominal or vaginal route. This study aims to assess the advantages of vaginal hysterectomy compared to abdominal hysterectomy in women with benign gynecological disorders other than prolapse. Aim of the study: The aim of this study was to compare the outcomes of vaginal hysterectomy and abdominal hysterectomy in treating benign non-prolapsed uterus. Methods: This cross-sectional comparative study was conducted among 60 patients at the Department of Obstetrics and Gynaecology, Institute of Child and Mother Health (ICMH), Dhaka, from May 2015 to October 2015. The study included 30 patients who underwent vaginal hysterectomy and 30 patients who underwent abdominal hysterectomy. Data collection involved recording patient history, conducting clinical examinations, and documenting information in a pre-designed data collection sheet. Data were analyzed using SPSS version 22.0. Result: This study included a total of 60 patients, with 30 undergoing abdominal hysterectomy (AH) and 30 undergoing vaginal hysterectomy (VH). Baseline characteristics were similar between the two groups. There were no intraoperative complications in either group. The operation time, intraoperative blood loss, time to out-of-bed activity, mean maximum postoperative body temperature, and duration of fever were all significantly shorter and less severe in the VH group compared with the AH group. Additionally, vaginal length in the VH group was significantly shorter than in the AH group. Conclusion: Vaginal hysterectomy offers advantages over abdominal hysterectomy in treating benign gynecological diseases, providing greater efficacy and safety with less invasiveness.

Clinical spectrum of acute poisoning among children visiting emergency at national institute of child health.

Objective: To determine the clinical spectrum of acute poisoning among children visiting emergency department. Study Design: Cross-sectional study. Setting: Department of Emergency, National Institute of Child Health, Karachi, Pakistan. Period: July 2023 to December 2023. Methods: Children of either gender, aged below 12 years and presenting with acute poisoning were analyzed. Demographic, clinical characteristics and final outcomes of children were reported. Results: In a total of 264 children, 139 (52.7%) were boys. The mean age was 4.79±2.02 years. Mode of poisoning was intentional in 31 (11.7%) children. Non-pharmaceutical exposure was reported in 183 (69.3%) children. Route of poisoning was through oral route in 178 (67.4%) children. The mean time to reach hospital was 80.95±77.77 minutes. Respiratory distress, drowsiness, vomiting, and cough were the most frequent presenting complaints, noted in 111 (42.0%), 43 (16.3%), 38 (14.4%), and 32 (12.1%) children, respectively. Type of poisoning substance were found to have significant association with age (p<0.001), time of presentation (p<0.001), mode of poisoning (p=0.011), place of poisoning (p<0.001), route of poisoning (p<0.001), first aid given (p<0.001), ambulance carrying the child to hospital (p<0.001), and final outcome (p<0.001). No mortality was reported. Conclusion: Acute poisoning most commonly affects children up to 5 years of age. Non-pharmaceutical exposure was reported in majority of acute poisoning cases. Respiratory distress, drowsiness, vomiting, and cough were the most frequent presenting complaints.

Frequency of occupational health hazards and factors responsible among the waste handlers at the tertiary care hospitals of Karachi.

Hospital waste handlers (HWHs) are in contact with contaminated waste that put them at risk for occupational health hazards. The objective of the study was to determine the frequency of occupational health hazards and identify factors contributing to them among the HWHs at tertiary care hospitals of Karachi. A cross sectional survey was conducted from January 2021 till June 2022 on 417 conveniently selected HWHs of the public and private tertiary care hospitals of the Karachi including three Public sector hospitals (Civil Hospital Karachi, National Institute of Child Health, Jinnah Post Graduate Medical Center) and five private sector hospitals (Sohail University Hospital, Darulsehat Hospital, Kharadar General Hospital, Patel Hospital and Hamdard University Hospital) using a structured questionnaire. Chi Square test was applied to determine the differences in occurrence of different hazardous outcomes (Needle stick injury, Sharp Injury, Eye Symptoms, Skin symptoms, Cough) between different groups of age, gender, type of hospitals and status of being trained in Hospital Waste Management (HWM). Around half of the HWHs (52.6%) labeled the bins of the waste according to their level of hazard. Only 17.9% disinfected the infected waste. The proportion of participants who experienced needle stick and sharp injury in the last six months was 16.3% and 15.8% respectively. Majority of them used disposable gloves (95.7%) and face masks (94.3%). One thirds had access to aprons while only 10.5% had access to protective shoes at their work place. HWHs of private sector were significantly less likely to experience Needle stick injuries, skin symptoms, cough, breathing difficulty and throat burning. The HWM practices in tertiary care hospitals of Karachi is far from being satisfactory. HWHs must be trained and monitored for safe disposal of waste.

Clinical presentations and outcomes of congenital and infantile nephrotic syndrome.

Objective: To describe the characteristics and outcomes of congenital nephrotic syndrome (CNS) and infantile nephrotic syndrome (INS). Study Design: Cross-sectional study. Setting: Department of Pediatric Nephrology, National Institute of Child Health, Karachi, Pakistan. Period: July 2023 to January 2024. Methods: All cases of CNS or INS visiting the outpatient, emergency department, or admitted in Nephrology ward were analyzed. Data including demographic characteristic and anthropometric measurements, clinical history and presentation were noted. Short-term outcomes in terms of cases who were discharged from hospital or those who died were recorded. Results: In a total of 33 infants, 17 (51.5%) were male. The mean age was 5.8±3.2 months. The mean days from onset of edema to the time of enrollment was 33.27±22.63 days. The most common presenting features were ascites noted in 4 (12.1%). Associated infections were reported in 21 (63.6%) infants. INS and CNS were noted in 25 (75.8%) and 8 (24.2%) infants respectively. Mortality was reported in 11 (33.3%) infants. Conclusion: Infections were the most common associated conditions in congenital and infantile nephrotic syndrome. Short term outcomes exhibiting high mortality rates warrants early identification and treatment of congenital and infantile nephrotic syndrome.

Effect of prematurely elevated late follicular progesterone on pregnancy outcomes following ovarian stimulation-intrauterine insemination for unexplained infertility: secondary analysis of the AMIGOS trial.

What is the relationship between late follicular phase progesterone levels and clinic pregnancy and live birth rates in couples with unexplained infertility undergoing ovarian stimulation with IUI (OS-IUI)? Late follicular progesterone levels between 1.0 and <1.5 ng/ml were associated with higher live birth and clinical pregnancy rates while the outcomes in groups with higher progesterone levels did not differ appreciably from the <1.0 ng/ml reference group. Elevated late follicular progesterone levels have been associated with lower live birth rates after fresh embryo transfer following controlled ovarian stimulation and egg retrieval, but less is known about whether an association exists with outcomes in OS-IUI cycles. Existing studies are few and have been limited to ovarian stimulation with gonadotrophins, but the use of oral agents, such as clomiphene citrate and letrozole, is common with these treatments and has not been well studied. The study was a prospective cohort analysis of the Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS) randomized controlled trial. Frozen serum was available for evaluation from 2121 cycles in 828 AMIGOS participants. The primary pregnancy outcome was live birth per cycle, and the secondary pregnancy outcome was clinical pregnancy rate per cycle. Couples with unexplained infertility in the AMIGOS trial, for whom female serum from day of trigger with hCG was available in at least one cycle of treatment, were included. Stored frozen serum samples from day of hCG trigger during treatment with OS-IUI were evaluated for serum progesterone level. Progesterone level <1.0 ng/ml was the reference group for comparison with progesterone categorized in increments of 0.5 ng/ml up to ≥3.0 ng/ml. Unadjusted and adjusted risk ratios (RR) and 95% CI were estimated using cluster-weighted generalized estimating equations to estimate modified Poisson regression models with robust standard errors. Compared to the reference group with 110/1363 live births (8.07%), live birth rates were significantly increased in cycles with progesterone 1.0 to <1.5 ng/ml (49/401 live births, 12.22%) in both the unadjusted (RR 1.56, 95% CI 1.14, 2.13) and treatment-adjusted models (RR 1.51, 95% CI 1.10, 2.06). Clinical pregnancy rates were also higher in this group (55/401 clinical pregnancies, 13.72%) compared to reference group with 130/1363 (9.54%) (unadjusted RR 1.46, 95% CI 1.10, 1.94 and adjusted RR 1.42, 95% CI 1.07, 1.89). In cycles with progesterone 1.5 ng/ml and above, there was no evidence of a difference in clinical pregnancy or live birth rates relative to the reference group. This pattern remained when stratified by ovarian stimulation treatment group but was only statistically significant in letrozole cycles. The AMIGOS trial was not designed to answer this clinical question, and with small numbers in some progesterone categories our analyses were underpowered to detect differences between some groups. Inclusion of cycles with progesterone values above 3.0 ng/ml may have included those wherein ovulation had already occurred at the time the IUI was performed. These cycles would be expected to experience a lower success rate but pregnancy may have occurred with intercourse in the same cycle. Compared to previous literature focusing primarily on OS-IUI cycles using gonadotrophins, these data include patients using oral agents and therefore may be generalizable to the wider population of infertility patients undergoing IUI treatments. Because live births were significantly higher when progesterone ranged from 1.0 to <1.5 ng/ml, further study is needed to clarify whether this progesterone range may truly represent a prognostic indicator in OS-IUI cycles.

Etiology, risk factors and antibiotic resistance in neonatal sepsis.

Objective: To determine the etiology, risk factors and antibiotic resistance in neonatal sepsis. Study Design: Cross-sectional study. Setting: Department of Pediatric Medicine, National Institute of Child Health, Karachi, Pakistan. Period: October 2023 to March 2024. Methods: A total of 174 neonates of both genders, with suspected neonatal sepsis were analyzed. Neonatal and maternal characteristics were noted. Blood sample was collected in aseptic environment and sent to institutional laboratory for blood culture and drug susceptibility testing. Results: In a total of 174 neonates, 101 (58.0%) were boys. The mean age, and weight were 9.61±7.86 years, and 2.25±0.85 kg, respectively. Neonatal sepsis on the basis of positive blood culture was reported in 38 (21.8%) neonates. Preterm birth had significant association with neonatal sepsis (44.7% vs. 26.5%, p=0.019). History of maternal UTI during pregnancy had significant linkage with neonatal sepsis (36.8% vs. 11.0%, p&lt;0.001). History of maternal fever during pregnancy had statistically significant association with neonatal sepsis (34.2% vs/ 19.1%, p=0.049). E. Coli, and Klebsiella were the most commonly found bacterial isolates, noted in 8 (21.1%), and 4 (10.5%) neonates, respectively. Most commonly used antimicrobial drugs were found to have high resistance rates against most frequent bacterial isolates. Conclusion: E. Coli, and Klebsiella were the most commonly found bacterial isolates in neonatal sepsis. Preterm birth, maternal history of UTI, and maternal history of fever were found to be significant factors linked to neonatal sepsis. Most commonly used antimicrobial drugs were found to have high resistance patterns which should raise alarms.

Response to Recombinant Human Growth Hormone (rhGH) Therapy in Children with Growth Hormone Deficiency.

To determine the auxological response to recombinant human growth hormone (rhGH) therapy in children with growth hormone deficiency (GHD) presenting at the National Institute of Child Health, Karachi, Pakistan. Observational study. Place and Duration of the Study:Department of Paediatric Endocrinology, National Institute of Child Health, Karachi, Pakistan, from January 2022 to December 2023. All pre-pubertal children with short stature aged 3-12 years diagnosed with GHD and who were prescribed rhGH therapy were included in the study. Children with any other underlying reason for short stature or any other comorbidity were excluded. Patients' demographics and baseline growth parameters were recorded in a pre-designed proforma. Patients were then followed up every three months till one year. Response to rhGH therapy was evaluated through comparison of growth parameters before and after one year of therapy. A total of 90 children including 47 (52.2%) males and 43 (47.8%) females with GHD were enrolled. Mean age of these patients was 7.92 ± 2.647 years. A statistically significant change in height (SD), Weight (SD), and BMI (SD) was observed before and after one year of therapy (p <0.001). Response to therapy in terms of height did not differ significantly with respect to gender (p = 0.955) or stimulated growth hormone levels (p = 0.911). However, response to rhGH therapy was significantly better in terms of increase in height, weight, and BMI in patients presenting earlier i.e. at age ≤8 years. Recombinant human growth hormone therapy was effective in children with short stature to achieve desirable growth. Children diagnosed and treated at a younger age (≤8years) achieve better height outcomes as compared to those presenting late.

Interpregnancy interval and adverse perinatal outcomes: A within-individual comparative method.

Previously observed associations between interpregnancy interval (IPI) and perinatal outcomes using a between-individual method may be confounded by unmeasured maternal factors. This study aims to examine the association between IPI and adverse perinatal outcomes using within-individual comparative analyses. We studied 10,647 individuals from the National Institute of Child Health and Human Development Consecutive Pregnancies Study in Utah with ≥3 liveborn singleton pregnancies. We matched two IPIs per individual and used conditional logistic regression to examine the association between IPI and adverse perinatal outcomes, including preterm birth (PTB, <37 weeks' gestation), small-for-gestational-age (SGA, <10th percentile of sex-specific birthweight for gestational age), low birthweight (LBW, <2,500 g), and neonatal intensive care unit (NICU) admission. Point and 95% confidence interval (CI) estimates were adjusted for factors that vary across pregnancies within individuals. CIsdid not unequivocally support either an increase or a decrease in the odds of PTB (adjusted odds ratio [aOR]: 1.31, 95% CI: 0.87, 1.96), SGA (aOR: 0.81, 95% CI: 0.51, 1.28), LBW (aOR: 1.59, 95% CI: 0.90, 2.80), or NICU admission (aOR: 0.96, 95% CI: 0.66, 1.40) for an IPI<6 months compared to 18-23-months IPI (reference), and neither did the CIs for the aOR of IPIs of 6-11 and 12-18 months compared to the reference. In contrast, an IPI≥24 months was associated with increased odds of LBW (aOR: 1.66, 95% CI: 1.03, 2.66 for 24-29 months; aOR: 2.27, 95% CI: 1.21, 4.29 for 30-35 months; and aOR: 2.09, 95% CI: 1.17, 3.72 for ≥36 months). Using a within-individual comparative method, we did not find evidence that a short IPI compared to the recommended IPI of 18-23 months was associated with increased odds of PTB, SGA, LBW, and NICU admission. IPI ≥ 24 months was associated with increased odds of delivering anLBW infant.

Early respiratory system reactance predicts respiratory outcomes in preterm infants: a retrospective, multicentre study.

This multicenter, international, retrospective study aims to investigate whether respiratory system reactance (Xrs) assessed by respiratory oscillometry on the 7th day of life is associated with respiratory outcomes in preterm infants below 32 weeks' gestation. Sinusoidal pressure oscillations (2-5 cmH2O peak-to-peak, 10 Hz) were superimposed on the positive end-expiratory pressure (PEEP). We assessed the association of Xrs z-score with the duration of respiratory support using linear regression and with bronchopulmonary dysplasia (BPD, according to Jensen et al. 2019) using logistic regression. We used the likelihood ratio test to evaluate whether Xrs z-score adds significantly to clinical predictors, including gestational age (GA), birth weight (BW) and the National Institute of Child Health and Human Development (NICHD) BPD prediction model. One hundred and thirty-seven infants (median (Q1, Q3) GA=28.43 (26.11, 30.29) weeks) were included; 44 (32%) developed BPD. Xrs z-score was significantly associated with the duration of respiratory support (R2=0.35). Xrs z-score was significantly higher in infants who developed BPD (p<0.001); the optimal cut-off value was 2.6, associated with 77% sensitivity and 80% specificity. In univariable analysis, per z-score increase in Xrs, the OR for BPD increased by 60% and the respiratory support by eight days. In multivariable analysis, Xrs z-score added significantly to the NICHD model and to GA and BW z-score to predict respiratory support duration (p=0.016 and p=0.014, respectively) and BPD development (p=0.003 and p<0.001, respectively). Xrs z-score on the 7th day after birth improves the prediction of respiratory outcome in preterm infants.

Temporal changes in cause of death among adolescents and adults in six countries in eastern and southern Africa in 1995–2019: a multi-country surveillance study of verbal autopsy data

The absence of high-quality comprehensive civil registration and vital statistics systems across many settings in Africa has led to little empirical data on causes of death in the region. We aimed to use verbal autopsy data to provide comparative, population-based estimates of cause-specific mortality among adolescents and adults in eastern and southern Africa. In this surveillance study, we harmonised verbal autopsy and residency data from nine health and demographic surveillance system (HDSS) sites in Kenya, Malawi, Tanzania, South Africa, Uganda, and Zimbabwe, each with variable coverage from Jan 1, 1995, to Dec 31, 2019. We included all deaths to adolescents and adults aged 12 or over that were residents of the study sites and had a verbal autopsy conducted. InSilicoVA, a probabilistic model, was used to assign cause of death on the basis of the signs and symptoms reported in the verbal autopsy. Levels and trends in all-cause and cause-specific mortality rates and cause-specific mortality fractions were calculated, stratified by HDSS site, sex, age, and calendar periods. 52 484 deaths and 5 157 802 person-years were reported among 1 071 913 individuals across the nine sites during the study period. 47 961 (91·4%) deaths had a verbal autopsy, of which 46 570 (97·1%) were assigned a cause of death. All-cause mortality generally decreased across the HDSS sites during this period, particularly for adults aged 20-59 years. In many of the HDSS sites, these decreases were driven by reductions in HIV and tuberculosis-related deaths. In 2010-14, the top causes of death were: road traffic accidents, HIV or tuberculosis, and meningitis or sepsis in adolescents (12-19 years); HIV or tuberculosis in adults aged 20-59 years; and neoplasms and cardiovascular disease in adults aged 60 years and older. There was greater between-HDSS and between-sex variation in causes of death for adolescents compared with adults. This study shows progress in reducing mortality across eastern and southern Africa but also highlights age, sex, within-HDSS, and between-HDSS differences in causes of adolescent and adult deaths. These findings highlight the importance of detailed local data to inform health needs to ensure continued improvements in survival.

Acetaminophen for Patent Ductus Arteriosus and Risk of Mortality and Pulmonary Morbidity.

Emerging data indicate that acetaminophen may adversely affect lung health. We examined whether acetaminophen compared with cyclooxygenase (COX) inhibitor alone for patent ductus arteriosus (PDA) is associated with mortality or respiratory morbidity in extremely preterm infants. This is a retrospective cohort study using data from the National Institute of Child Health and Human Development Neonatal Research Network. Infants were born at 22 to 28 weeks' gestation or weighing 401 to 1000 g between 2016 and 2020 and received acetaminophen, ibuprofen, and/or indomethacin for PDA closure. The primary outcome was death or grade 2 to 3 bronchopulmonary dysplasia (BPD) at 36 weeks' postmenstrual age. Secondary outcomes included predischarge mortality and respiratory morbidities. Risk ratios were adjusted for baseline and early postnatal factors. Additional exploratory analyses were adjusted for later postnatal covariates. Of 1921 infants, 627 (32.6%) received acetaminophen and 1294 (67.3%) received COX inhibitor only. Multidrug therapy (42.9% vs 4.7%) and surgical or catheter PDA closure (26.5% vs 19.9%) were more common among acetaminophen-exposed infants. Death or grade 2 to 3 BPD at 36 weeks' postmenstrual age was similar between infants treated with acetaminophen versus COX inhibitor only (57.1% vs 58.3%; adjusted relative risk [aRR] 0.96, 95% confidence interval [CI] 0.87-1.06). Acetaminophen was associated with increased risk of predischarge mortality (13.3% vs 10.0%) when adjusting for perinatal and early postnatal factors (aRR 1.42, 95% CI 1.02-1.93), but not in exploratory analyses that included later postnatal factors (aRR 1.28, 95% CI 0.91-1.82). Treatment with acetaminophen versus COX inhibitor alone for PDA was not associated with the composite outcome of death or BPD in extremely preterm infants. Our results support further evaluation of whether acetaminophen for PDA increases mortality.

Obesity- and diet-induced plasticity in systems that control eating and energy balance.

In April 2023, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), in partnership with the National Institute of Child Health and Human Development, the National Institute on Aging, and the Office of Behavioral and Social Sciences Research, hosted a 2-day online workshop to discuss neural plasticity in energy homeostasis and obesity. The goal was to provide a broad view of current knowledge while identifying research questions and challenges regarding neural systems that control food intake and energy balance. This review includes highlights from the meeting and is intended both to introduce unfamiliar audiences with concepts central to energy homeostasis, feeding, and obesity and to highlight up-and-coming research in these areas that may be of special interest to those with a background in these fields. The overarching theme of this review addresses plasticity within the central and peripheral nervous systems that regulates and influences eating, emphasizing distinctions between healthy and disease states. This is by no means a comprehensive review because this is a broad and rapidly developing area. However, we have pointed out relevant reviews and primary articles throughout, as well as gaps in current understanding and opportunities for developments in the field.

Recent Developments in Promising Hormonal and Non- Hormonal Male Contraceptives: A Review

New male contraceptive methods would expand male and female contraceptive alternatives and enhance male contraceptive agency. Since 1969, a program for developing contraceptives has been financed by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, which also continues to fund the majority of hormonal male contraceptive development today. Also, the early stages of non-hormonal techniques start to develop. The hormonal male contraceptive methods, include testosterone undecanoate injection plus norethisterone enanthate injection, implants of testosterone plus depo-medroxyprogesterone acetate injection, testosterone enanthate injection, and other testosterone-based methods. The non-hormonal methods, include novel hormone-free substances such as retinoic acid inhibitors, sperm ion channel blockers, and vasal peristalsis blockers. The review provides insights into the efficacy, safety, and potential side effects of each method, and highlights the current state of research and development in the field of male contraception.

Care-seeking for difficulties conceiving in sub-Saharan Africa: findings from population-based surveys in eight geographies.

What is the nature of women's care-seeking for difficulties conceiving in sub-Saharan Africa (SSA), including the correlates of seeking biomedical infertility care at a health facility? Care-seeking for difficulties getting pregnant was low, much of which involved traditional or religious sources of care, with evidence of sociodemographic disparities in receipt of biomedical care. Nearly all research on infertility care-seeking patterns in SSA is limited to clinic-based studies among the minority of people in these settings who obtain facility-based services. In the absence of population-based data on infertility care-seeking, we are unable to determine the demand for services and disparities in the use of more effective biomedical sources of care. We used cross-sectional, population-based data from the Performance Monitoring for Action (PMA) female survey in eight geographies in SSA, including nationally representative data from Burkina Faso, Côte d'Ivoire, Kenya, and Uganda and regionally representative data from two provinces in the Democratic Republic of the Congo (DRC) (Kinshasa and Kongo Central) and two states in Nigeria (Kano and Lagos). We employed a multi-stage cluster random sampling design with probability proportional to size selection of clusters within each geography to produce representative samples of women aged 15-49. Samples ranged from 1144 in Kano, Nigeria, to 9489 in Kenya. PMA collected these data between November 2021 and December 2022. We restricted the sample to women who had ever had sex, with analytic samples ranging from 854 in Kano to 8,059 in Kenya, then conducted descriptive and bivariable analyses to examine characteristics of those who sought care for difficulties getting pregnant. Among those who reported seeking care, we conducted bivariable and multivariable logistic regression analyses to determine factors associated with receipt of biomedical services from a health facility. All analyses were conducted separately by geography. Our study found low levels of care-seeking for difficulties getting pregnant among sexually active women in eight geographies in SSA, ranging from 3.7% (Kenya) to 15.3% (Côte d'Ivoire). Of this, 51.8% (Burkina Faso) to 86.7% (Kinshasa) involved receipt of biomedical services in health facilities. While many factors were consistently associated with infertility care-seeking from any source across geographies, factors associated with receipt of biomedical care specifically were less pronounced. This may be a result of the highly limited sources of infertility services in SSA; thus, even privileged groups may struggle to obtain effective treatment for difficulties getting pregnant. However, we did observe disparities in biomedical care-seeking in our bivariable results in several geographies, with the wealthiest women, those with more education, and those residing in urban areas generally more likely to have sought biomedical care for difficulties getting pregnant. Our data lacked details on the nature of the services received and outcomes, and we do not have information on reasons why women chose the sources they did. Small samples of women who sought care limited our power to detect significant differences in care-seeking by women's characteristics in several geographies. Infertility and access to appropriate treatment are issues of reproductive health and human rights. While our results do not indicate to what extent use of non-biomedical sources of care is driven by preferences, cost, or lack of accessible services, it is clear from our results and existing literature that more needs to be done to ensure access to affordable, quality, cost-effective infertility services in SSA. This study was supported by grants from the Bill & Melinda Gates Foundation (INV009639) and the National Institute of Child Health and Human Development (K01HD107172). The funders were not involved in the study design, analyses, manuscript writing, or the decision to publish. The authors have no conflicts of interest to declare. N/A.

Genomic Differences between Spontaneous versus Indicated Extreme Preterm Birth.

Extremely preterm infants are at high risk of neonatal mortality and morbidity. Extreme preterm birth (PTB) may result from spontaneous preterm labor or preterm premature rupture of membranes or may be indicated due to preeclampsia, eclampsia, hypertension, or other causes. Our objective was to identify single nucleotide polymorphisms (SNPs) and biological pathways associated with spontaneous versus indicated extreme PTB using the neonatal genome. We evaluated 523 spontaneous births and 134 indicated births weighing 401 to 1,000 g at birth from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network's Genomics dataset by genome-wide association study (GWAS) and pathway analysis. The TOLSURF cohort was used to replicate the results. In the NRN GWAS, no statistically significant results were found, although the Manhattan plot showed one almost significant peak (rs60854043 on chromosome 14 at p = 1.03E-07) along with many other modest peaks at p = 1-9E-06, for a total of 15 suggestive associations at this locus. In the NRN pathway analysis, multiple pathways were identified, with the most significant being "GO_mf:go_low_density_lipoprotein_particle_receptor_activity" at p = 1.14E-06. However, these results could not be replicated in the TOLSURF cohort. Genomic differences are seen between infants born by spontaneous versus indicated extreme PTB. Due to the limited sample size, there is a need for larger studies. · Genomic differences are seen between infants born by spontaneous versus indicated very PTB.. · Future studies with large sample sizes evaluating extreme PTB are necessary.. · Spontaneous PTB is more common than indicated extreme PTB..

Clinical spectrum of acute flaccid paralysis among pediatric patients at the National Institute of Child Health, Karachi, Pakistan.

Objective: To evaluate the clinical spectrum and immediate outcomes of acute flaccid paralysis (AFP) in children presenting at National Institute of Child Health, Karachi, Pakistan. Study Design: Cross-sectional study. Setting: Department of Pediatrics, NICH, Karachi, Pakistan. Period: August 2023 to January 2024. Methods: A total of 121 children of either gender, aged 1-15 years, and presenting with AFP were analyzed. AFP was diagnosed by nerve conduction study. Causes of AFP, like Guillian Barre Syndrome (GBS), transverse myelitis, traumatic neuritis were noted. Outcomes were noted in terms of discharged from hospital, left against medical advice, and mortality. Results: In a total of 121 children, 75 (62.0%) were boys. The mean age was 6.00±2.88 years, ranging between 1-12 years. There were 74 (61.2%) children who were fully vaccinated as per age. The most common cause of AFP were GBS, transverse myelitis, and hypokalemic paralysis, noted in 49 (40.5%), 19 (15.7%), and 15 (12.4%) children, respectively. Ninety (74.4%) children were discharged after the treatment, 10 (8.3%) left against medical advice, whereas mortality was noted in 21 (17.4%) children. Children leaving against medical advice were left out from the analysis to compared final outcomes with respect to various study variables. Incomplete vaccination status (p=0.0006), and presentation with sensory loss (p=0.0003) were found to have significant association with mortality. Conclusion: Guillian Barre Syndrome was found to be the most common cause behind acute flaccid paralysis in children. Incomplete vaccination history, and presenting with sensory loss were associated with poor outcomes.

Prevalence of chronic kidney disease in children of school going age visiting outpatient department of A Tertiary Care Hospital in Karachi, Pakistan.

Objective: To determine the prevalence of chronic kidney disease (CKD) among children of school-going age. Study Design: Cross-sectional study. Setting: Department of Pediatric Medicine, National Institute of Child Health, Karachi, Pakistan. Period: July 2023 to December 2023. Methods: A total of 130 children of both genders, aged between 5-15 years, visiting outpatient department of pediatric medicine were analyzed. Demographic and clinical information were noted. Laboratory investigations like urinalysis and serum creatinine were performed. CKD was diagnosed on the basis of “Kidney Disease Outcomes Quality Initiative (KDOQI)” guidelines. Results: In a total of 130 children, 67 (51.5%) children were male. Overall, the mean age was 8.43±2.45 years. Hypertension was diagnosed in 10 (7.7%) children. Anemia was present in 103 (79.2%) patients. The mean hemoglobin, serum creatinine, and blood urea nitrogen were 9.41±1.98 g/dl, 0.48±0.37 mg/dl, and 34.20±33.18 mg/dl, respectively. CKD was diagnosed in 10 (7.7%) children. Among these 10 children diagnosed with CKD, 7 were having CKD stage-1 whereas CKD stage-2 was noted in 3 children. Presence of hypertension (p=0.006), and albuminuria (p&lt;0.001) were associated with CKD. Conclusion: The prevalence of CKD in school going age children was 7.7%. Presence of hypertension, and albuminuria were linked with CKD.

Measurement of Orbital Dimensions and Its Gender Related Differences in Various Ages of Pakistani Children

Purpose: To measure the orbital dimensions and their gender related differences at various ages in Pakistani children from birth to 12 years of age. Study Design: Cross sectional observational. Place and Duration of Study: Tibri Medical College and Hospital Karachi and National Institute of Child Health, Karachi from June 2022 to February 2023. Methods: Patients who underwent CT Scan head for any reason but with normal orbits were included in the study. The vertical and horizontal measurements were made for anterior, middle and posterior orbit in sagittal and axial views. Results: The mean age of the total sample of 176 children was 6.45±3.40 years. The mean horizontal dimension of the anterior side of the orbit was 28.31 mm for children aged 1-3 years, 30.63 mm for those aged 4-6 years, 32.22 mm for ages 6-9 years, and 32.93 mm for ages 10-12 years. These differences were statistically significant (p&lt;0.05). A significant difference was observed in the mean vertical dimension for the middle and posterior sides across different age groups. There were significant differences in the vertical and horizontal dimensions of the anterior and middle sides of the orbits for children aged 1-3 years (p&lt;0.05). However, for children aged 4-6 years, there were no significant differences between genders in any measured dimension (horizontal, vertical, or depth) (p&gt;0.05). Conclusion: There is a phase of rapid growth from birth to 3 years of age, after which the orbit continues to grow slowly. Gender-related differences were more pronounced during this phase.
