Predictors of Preterm Neonatal Mortality in India and Pakistan: A Secondary Analysis of Data from PURPOSe Study.

Objective. To create a prediction model for preterm neonatal mortality. Methods. A secondary analysis was conducted using data from a prospective cohort study, the Project to Understand and Research Preterm Pregnancy Outcome South Asia. The Cox proportional hazard model was used and adjusted hazard ratios (AHR) with 95% confidence intervals (95% CI) were reported. Results. Overall, 3446 preterm neonates were included. The mean age of preterm neonates was 0.65 (1.25) hours and 52% were female. The preterm neonatal mortality rate was 23.3%. The maternal factors predicting preterm neonatal death was any antepartum hemorrhage, AHR 1.99 (1.60-2.47), while neonatal predictors were preterm who received positive pressure ventilation AHR 1.30 (1.08-1.57), temperature <35.5°C AHR 1.18 (1.00-1.39), and congenital malformations AHR 3.31 (2.64-4.16). Conclusion. This study identified key maternal and neonatal predictors of preterm neonatal mortality, emphasizing the need for targeted interventions and collaborative public health efforts to address disparities and regional variations.

Infancy-onset diabetes caused by de-regulated AMPylation of the human endoplasmic reticulum chaperone BiP.

Dysfunction of the endoplasmic reticulum (ER) in insulin-producing beta cells results in cell loss and diabetes mellitus. Here we report on five individuals from three different consanguineous families with infancy-onset diabetes mellitus and severe neurodevelopmental delay caused by a homozygous p.(Arg371Ser) mutation in FICD. The FICD gene encodes a bifunctional Fic domain-containing enzyme that regulates the ER Hsp70 chaperone, BiP, via catalysis of two antagonistic reactions: inhibitory AMPylation and stimulatory deAMPylation of BiP. Arg371 is a conserved residue in the Fic domain active site. The FICDR371S mutation partially compromises BiP AMPylation in vitro but eliminates all detectable deAMPylation activity. Overexpression of FICDR371S or knock-in of the mutation at the FICD locus of stressed CHO cells results in inappropriately elevated levels of AMPylated BiP and compromised secretion. These findings, guided by human genetics, highlight the destructive consequences of de-regulated BiP AMPylation and raise the prospect of tuning FICD's antagonistic activities towards therapeutic ends.

Identifying the current status and future needs of clinical, educational, and laboratory genetics services in Pakistan: a web-based panel discussion.

While the prevalence of genetic disorders has been well documented in the Muslim-majority, low-socioeconomic country of Pakistan, the provision of medical genetic services remains limited and cost-prohibitive to the masses in the country. With the objective of identifying gaps in the provision of medical genetics services as perceived by the healthcare providers and the general public, the Pakistani Society of Medical Genetics and Genomics (PSMG) organized a needs assessment webinar on December 6, 2020, titled, "A Vibrant Discussion on the Current Status and Future Needs of Medical Genetic Services in Pakistan." The objectives of the webinar were (1) to explore the current availability of medical genetics services, (2) to identify areas in clinical genetics delivery models needed to improve the state of medical genetics in the country, and (3) to garner the interest in such provisions from the expert and lay audience. The webinar consisted of a moderator-led, structured interview of an expert panel including the following topics: (1) postgraduate clinical genetics and genetic counseling training programs, (2) medical genetics clinics and formal genetic counseling services), (3) clinical genetic testing and (4) patient support and advocacy groups. The webinar was followed by a short, web-based survey completed by 35 of the 60 attendees. The results of this survey indicated overwhelming support for establishing formal genetic counseling educational opportunities (91.6%) and increasing the availability of genetic testing (100%). This report further summarizes the opinions and recommendations of the panelists and the audience survey results.

The causes of preterm neonatal deaths in India and Pakistan (PURPOSe): a prospective cohort study.

BACKGROUND: Preterm birth remains the major cause of neonatal death worldwide. South Asia contributes disproportionately to deaths among preterm births worldwide, yet few population-based studies have assessed the underlying causes of deaths. Novel evaluations, including histological and bacteriological assessments of placental and fetal tissues, facilitate more precise determination of the underlying causes of preterm deaths. We sought to assess underlying and contributing causes of preterm neonatal deaths in India and Pakistan. METHODS: The project to understand and research preterm pregnancy outcomes and stillbirths in South Asia (PURPOSe) was a prospective cohort study done in three hospitals in Davangere, India, and two hospitals in Karachi, Pakistan. All pregnant females older than 14 years were screened at the time of presentation for delivery, and those with an expected or known preterm birth, defined as less than 37 weeks of gestation, were enrolled. Liveborn neonates with a weight of 1000 g or more who died by 28 days after birth were included in analyses. Placentas were collected and histologically evaluated. In addition, among all neonatal deaths, with consent, minimally invasive tissue sampling was performed for histological analyses. PCR testing was performed to assess microbial pathogens in the placental, blood, and fetal tissues collected. An independent panel reviewed available data, including clinical description of the case and all clinical maternal, fetal, and placental findings, and results of PCR bacteriological investigation and minimally invasive tissue sampling histology, from all eligible preterm neonates to determine the primary and contributing maternal, placental, and neonatal causes of death. FINDINGS: Between July 1, 2018, and March 26, 2020, of the 3470 preterm neonates enrolled, 804 (23%) died by 28 days after birth, and, of those, 615 were eligible and had their cases reviewed by the panel. Primary maternal causes of neonatal death were hypertensive disease (204 [33%] of 615 cases), followed by maternal complication of pregnancy (76 [12%]) and preterm labour (76 [11%]), whereas the primary placental causes were maternal and fetal vascular malperfusion (172 [28%] of 615) and chorioamnionitis, funisitis, or both (149 [26%]). The primary neonatal cause of death was intrauterine hypoxia (212 [34%] of 615) followed by congenital infections (126 [20%]), neonatal infections (122 [20%]), and respiratory distress syndrome (126 [20%]). INTERPRETATION: In south Asia, intrauterine hypoxia and congenital infections were the major causes of neonatal death among preterm babies. Maternal hypertensive disorders and placental disorders, especially maternal and fetal vascular malperfusion and placental abruption, substantially contributed to these deaths.

The causes of stillbirths in south Asia: results from a prospective study in India and Pakistan (PURPOSe).

BACKGROUND: South Asia contributes more than a third of all global stillbirths, yet the causes remain largely unstudied in this region. New investigations, including novel assessments of placental and fetal tissues, facilitate more precise determination of the underlying causes of stillbirth. We sought to assess underlying and contributing causes of stillbirth from settings in India and Pakistan. METHODS: In this prospective cohort study (PURPOSe), we report the cause of death in stillbirths in hospitals in central India and south Pakistan (Davangere, India [three public and private hospitals] and Karachi, Pakistan [one public maternity and one children's hospital]). Women aged 15 years or older and with a known stillbirth (defined as a pregnancy at 20 or more weeks of gestation with the in-utero death of a fetus) weighing 1000 g or more were included in the study. Maternal clinical factors, placental evaluation, fetal tissue evaluation (from minimally invasive tissue sampling), and PCR for microbial pathogens were used to identify the causes of death. An expert panel reviewed available data for all stillbirths to identify the primary and contributing maternal, placental, and fetal causes of stillbirth. FINDINGS: Between Sept 1, 2018, and Feb 12, 2020, 981 stillborns were included and, of those, 611 were reviewed by the expert panel. The primary maternal causes of stillbirth were hypertensive disease in 221 (36%) of 611 stillbirths, followed by severe anaemia in 66 (11%) stillbirths. The primary placental causes were maternal and fetal vascular malperfusion, in 289 (47%) stillbirths. The primary fetal cause of stillbirth was intrauterine hypoxia, in 437 (72%) stillbirths. We assessed the overlap of main causes and 116 (19%) stillbirths had intrauterine hypoxia, placental malperfusion, and eclampsia or pre-eclampsia indicated as primary causes of death. Infection (including of the placenta, its membranes, and in the fetus) and congenital anomalies also were causative of stillbirth. INTERPRETATION: In south Asia, fetal asphyxia is the major cause of stillbirth. Several placental lesions, especially those associated with maternal and fetal vascular malperfusion and placental abruption, have an important role in asphyxia and fetal death. Maternal hypertension, and especially pre-eclampsia, is often the primary maternal condition associated with this pathway. FUNDING: Bill & Melinda Gates Foundation.

Birth asphyxia is under-rated as a cause of preterm neonatal mortality in low- and middle-income countries: A prospective, observational study from PURPOSe.

OBJECTIVE: To assess respiratory distress syndrome (RDS) compared with birth asphyxia as the cause of death in preterm newborns, assigned by the neonatal intensive care unit (NICU) physician at the time of death and assigned by a panel with complete obstetric history, placental evaluation, tissue histology and microbiology. DESIGN: Prospective, observational study. SETTINGS: Study NICUs in India and Pakistan. POPULATION: Preterm infants delivered in study facility. METHODS: A total of 410 preterm infants who died in the NICU with cause of death ascertained by the NICU physicians and independently by expert panels. We compared the percentage of cases assigned RDS versus birth asphyxia as cause of death by the physician and the panel. MAIN OUTCOME MEASURES: RDS and birth asphyxia. RESULTS: Of 410 preterm neonatal deaths, the discharging NICU physicians found RDS as a cause of death among 83.2% of the cases, compared with the panel finding RDS in only 51.0%. In the same neonatal deaths, the NICU physicians found birth asphyxia as a cause of death in 14.9% of the deaths, whereas the panels found birth asphyxia in 57.6% of the deaths. The difference was greater in Pakistan were the physicians attributed 89.7% of the deaths to RDS and less than 1% to birth asphyxia whereas the panel attributed 35.6% of the deaths to RDS and 62.7% to birth asphyxia. CONCLUSIONS: NICU physicians who reported cause of death in deceased preterm infants less often attributed the death to birth asphyxia, and instead more often chose RDS, whereas expert panels with more extensive data attributed a greater proportion of deaths to birth asphyxia than did the physicians.

Early suspicion can save lives; mucormycosis in two children with diabetic ketoacidosis in Pakistan.

Mucormycosis is a cause of fulminant necrotising fungal infection in children with underlying immunocompromising conditions. Rhino-orbito-cerebral infection is its most common form in the paediatric group with uncontrolled diabetes mellitus or diabetic ketoacidosis. The initial presentation can mimic a bacterial infection; thus a high index of suspicion is needed for timely intervention to reduce morbidity and mortality. We have presented a case of rhino-orbito-cerebral mucormycosis (ROCM) in two patients with diabetic ketoacidosis for the first time from Pakistan. Both the patients couldnot survive due to extensive disease on late presentation.

X-linked Adrenoleukodystrophy in a 20-Year-Old Male With an ABCD1 Gene Mutation: First Case From Pakistan.

X-linked adrenoleukodystrophy (X-ALD) is a rare neurodegenerative disease characterized by genetic mutation of the ABCD1 gene. This gene encodes for transmembrane adrenoleukodystrophy protein (ALDP). Defective ALDP protein results in the accumulation of a very long chain fatty acid (VLCFA) within certain tissues and plasma. X-ALD can initially present as Addison's disease (primary adrenal insufficiency) as the accumulation of VLCFA most importantly occurs in the adrenal gland. Our 20-year-old male patient, a known case of Addison's disease, presented with vision loss, neurologic symptoms, and psychiatric issues. Neurologic symptoms included poor concentration and memory, while psychiatric problems included primarily depressive disorder and mild psychotic behavior. His Addison's disease was secondary to X-ALD. Still, he was diagnosed late due to a lack of awareness of X-ALD and a lack of resources for genetic testing in Pakistan. Therefore, the purpose of this case report is to spread knowledge and understanding of X-ALD, so that it can be ruled out as the potential cause of adrenal insufficiency in young patients, particularly males diagnosed with Addison's disease. Moreover, if the patient presents with Addison's disease and psychiatric issues, they should be tested to rule out X-ALD.

Access to fludrocortisone and to hydrocortisone in children with congenital adrenal hyperplasia in the WHO Eastern Mediterranean Region: it takes a village .

Congenital adrenal hyperplasia (CAH), if untreated, carries high morbidity and mortality. A higher incidence of CAH is expected in countries where consanguinity is common, such as in the countries of the WHO Eastern Mediterranean Region (EMRO). CAH is managed through lifelong treatment with fludrocortisone and hydrocortisone. In this analysis, performed in the 22 EMRO countries and territories plus Algeria, we review which countries offer a neonatal screening programme for CAH and describe the barriers and opportunities to access oral fludrocortisone and oral and injectable hydrocortisone. Neonatal CAH screening was only available nationally in Qatar, Kuwait and partially in Lebanon and Saudi Arabia. We reviewed the national lists of essential medicines (NEMLs) and found that 13/23 (57%) countries included fludrocortisone and 18/23 (78%) included oral hydrocortisone. Fludrocortisone was not included by any of the low-income countries and oral hydrocortisone was only included by one low-income country. We then contacted paediatric endocrinologists in each country to assess perceived availability of these medicines. Overall, there was a relatively good consistency between inclusion of fludrocortisone and hydrocortisone in the NEML and their actual availability in a country. We propose several mechanisms to improve access, including prequalification by the WHO, a common registration process for groups of countries, pooled procurement, working with local pharmaceutical companies, special access status for medicines not yet registered in a country and compounding. We suggest that access to medicines requires a collaboration between health professionals, families of patients, health authorities, pharmaceutical companies and the WHO.

Peak Growth Hormone Level Variability during Insulin Tolerance Test in Children with Short Stature.

OBJECTIVE: To determine the variations in peak growth hormone levels during insulin tolerance test (ITT) in diagnosis of growth hormone deficiency (GHD) in children presenting with short stature. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Department of Pediatric Endocrinology, National Institute of Child Health (NICH), from January to December 2018. METHODOLOGY: Clinical records of all children who underwent ITT during the above mentioned period were reviewed. All 348 children of either gender from 2-17 years of age with height more than 2SD below the mean (<3rd percentile) suspected GHD and subjected for ITT were included. Verbal consent was taken from all parents. Children below 2 years and with other causes of Short Stature like hypothyroid, celiac, cardiac, chronic liver, kidney diseases and syndrome were excluded. RESULTS: Total 348 children were subjected to ITT. Out of these 48.3% were found to have GH levels <5ng/ml, 33.6% b/w 5-10 ng/ml and 18.1% >10 ng/ml. Precisely peak GH levels at different time intervals are 1.1%, 19.3%, 47.4%, 29.9%, and 2.3% for 0, 30, 60, 90 and 120 minutes respectively. Mostly peak growth hormone levels were accomplished at 60 minutes followed by 90 and then at 30 minutes. Hypoglycemia was achieved 0.8%, 47%, 26%, 24% and 1% at 0, 30, 60, 90, and 120 minutes. CONCLUSION: The 0, 30, 60, and 90 minutes samples are adequate to confirm the diagnosis of GH deficiency. This shorter duration of ITT to 90 minutes is cost effective as it decreases the financial burden of unnecessary testing. Additionally, it reduces the risk of side effect like hypoglycemia. Key Words: Short stature, Growth hormone deficiency, Insulin tolerance test.

Monogenic diabetes in Pakistani infants and children: challenges in a resource poor country.

OBJECTIVES: To review the data of infants and children with suspected monogenic diabetes who underwent genetic testing. METHODS: Monogenic diabetes is a rare form of diabetes resulting from mutations in a single gene. It can be caused by dominant as well as recessive modes of inheritance. In a country like Pakistan where interfamily marriages are common the incidence of genetic disorders is increased. As Pakistan a resource-poor country, the diagnosis of insulin-dependent diabetes is often delayed and a genetic diagnosis of monogenic diabetes is extremely difficult. Children with clinical diagnosis of monogenic and syndromic diabates were recruited and blood samples were sent for genetic analysis. RESULTS: One thousand sixty four new cases diagnosed with type 1 diabetes were registered at the National Institute of Child Health, Karachi, in the last 10 years. Of these 39 patients were selected for genetic testing who were diagnosed with diabetes/had a sibling diagnosed with diabetes before the age of nine months (n = 27) or had extra pancreatic features ( n= 12). We identified mutations in 18/27 cases diagnosed with diabetes before nine months of age. The most common genetic subtype was WolcottRallison syndrome caused by EIF2AK3 mutations (seven cases). KCNJ11 mutations were identified in two cases, ABCC8mutations were identified in four cases from three families, GCK and INS mutations were each identified in two cases, and one SLC2A2 mutation was identified in one case. A genetic diagnosis was made in 12/12 children from six families with diabetes diagnosed after the age of nine months who had extrapancreatic features. Six patients had genetically confirmed Wolfram syndrome (WFS1), three had thiamine-responsive megaloblastic anemia (SLC19A2) and three were diagnosed with histocytosis lymphadenopathy plus syndrome (SLC29A3). CONCLUSIONS: Genetic testing is essential to confirm a diagnosis of monogenic diabetes which guides clinical management and future counselling. Our study highlights the importance of diagnosing monogenic diabetes in the largely consanguineously-married population of Pakistan.

Typhoid and Paratyphoid Cost of Illness in Pakistan: Patient and Health Facility Costs From the Surveillance for Enteric Fever in Asia Project II.

BACKGROUND: The objective of this study was to estimate the cost of illness from enteric fever (typhoid and paratyphoid) at selected sites in Pakistan. METHODS: We implemented a cost-of-illness study in 4 hospitals as part of the Surveillance for Enteric Fever in Asia Project (SEAP) II in Pakistan. From the patient and caregiver perspective, we collected direct medical, nonmedical, and indirect costs per case of enteric fever incurred since illness onset by phone after enrollment and 6 weeks later. From the health care provider perspective, we collected data on quantities and prices of resources used at 3 of the hospitals, to estimate the direct medical economic costs to treat a case of enteric fever. We collected costs in Pakistani rupees and converted them into 2018 US dollars. We multiplied the unit cost per procedure by the frequency of procedures in the surveillance case cohort to calculate the average cost per case. RESULTS: We collected patient and caregiver information for 1029 patients with blood culture-confirmed enteric fever or with a nontraumatic terminal ileal perforation, with a median cost of illness per case of US $196.37 (IQR, US $72.89-496.40). The median direct medical and nonmedical costs represented 8.2% of the annual labor income. From the health care provider perspective, the estimated average direct medical cost per case was US $50.88 at Hospital A, US $52.24 at Hospital B, and US $11.73 at Hospital C. CONCLUSIONS: Enteric fever can impose a considerable economic burden in Pakistan. These new estimates of the cost of illness of enteric fever can improve evaluation and modeling of the costs and benefits of enteric fever prevention and control measures, including typhoid conjugate vaccines.

Spectrum of Addison's Disease in Children.

OBJECTIVE: To determine the clinical presentation of Addison's disease in order to increase the awareness of presentation in Pakistani children. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Department of Diabetes and Endocrinology, National Institute of Child Health, Karachi, Pakistan, from 2015 to 2019. METHODOLOGY: Sixty-three children of Addison's disease were enrolled in the study, who have visited and facilitated from the services of National Institute of Child Health from urban and rural region of the Sindh province. Diagnosis were made through biochemical analysis and detailed examination of acute and chronic symptoms. Study was initiated after taking the approval from Institutional Review Board. Moreover, written informed consents were also taken from each of the study participant. RESULTS: There were 36 boys and 27 girls with a mean age at diagnosis of 3.92 and 4.96 years, respectively. Twelve patients were presented with an adrenal crisis following an acute illness. All of them had hyponatraemia; however, 10 had a hyperkalaemia and 8 had been reported with hypoglycaemia. Increased skin pigmentation was observed in 45 children with other identifiable features including weight loss, lethargy, and poor response in activities. Moreover 15 of them were identified with associated disorder (autoimmune polyendocrinopattay syndrome (APS), Allgrove or triple A syndrome, and adrenoleukodystrophy).  Conclusion: Typical and atypical presentations of Addison's disease in children of Pakistani population are defined in this study which may assist in better management of Addison's patients. Key Words: Adrenal crisis, Hyponatremia, Hyperkalemia, APS, Allgrove, Adrenoleukodystrophy.

We All Have a Role to Play: Redressing Inequities for Children Living with CAH and Other Chronic Health Conditions of Childhood in Resource-Poor Settings.

CLAN (Caring and Living as Neighbours) is an Australian-based non-governmental organisation (NGO) committed to equity for children living with chronic health conditions in resource-poor settings. Since 2004, CLAN has collaborated with a broad range of partners across the Asia Pacific region to improve quality of life for children living with congenital adrenal hyperplasia (CAH). This exploratory case study uses the Knowledge to Action (KTA) framework to analyse CLAN's activities for children living with CAH in the Asia Pacific. The seven stages of the KTA action cycle inform a systematic examination of comprehensive, collaborative, sustained actions to address a complex health challenge. The KTA framework demonstrates the "how" of CLAN's approach to knowledge creation and exchange, and the centrality of community development to multisectoral collaborative action across a range of conditions, cultures and countries to redressing child health inequities. This includes a commitment to: affordable access to essential medicines and equipment; education, research and advocacy; optimisation of medical management; encouragement of family support groups; efforts to reduce financial burdens; and ethical, transparent program management as critical components of success. Improvements in quality of life and health outcomes are achievable for children living with CAH and other chronic health conditions in resource-poor settings. CLAN's strategic framework for action offers a model for those committed to #LeaveNoChildBehind.

Analysis of variants in GATA4 and FOG2/ZFPM2 demonstrates benign contribution to 46,XY disorders of sex development.

BACKGROUND: GATA-binding protein 4 (GATA4) and Friend of GATA 2 protein (FOG2, also known as ZFPM2) form a heterodimer complex that has been shown to influence transcription of genes in a number of developmental systems. Recent evidence has also shown these genes play a role in gonadal sexual differentiation in humans. Previously we identified four variants in GATA4 and an unexpectedly large number of variants in ZFPM2 in a cohort of individuals with 46,XY Differences/Disorders of Sex Development (DSD) (Eggers et al, Genome Biology, 2016; 17: 243). METHOD: Here, we review variant curation and test the functional activity of GATA4 and ZFPM2 variants. We assess variant transcriptional activity on gonadal specific promoters (Sox9 and AMH) and variant protein-protein interactions. RESULTS: Our findings support that the majority of GATA4 and ZFPM2 variants we identified are benign in their contribution to 46,XY DSD. Indeed, only one variant, in the conserved N-terminal zinc finger of GATA4, was considered pathogenic, with functional analysis confirming differences in its ability to regulate Sox9 and AMH and in protein interaction with ZFPM2. CONCLUSIONS: Our study helps define the genetic factors contributing to 46,XY DSD and suggests that the majority of variants we identified in GATA4 and ZFPM2/FOG2 are not causative.

Van Wyk Grumbach Syndrome.

Van Wyk Grumbach syndrome is well known for protracted hypothyroidism, characterised by multicystic ovaries (normal size ovaries contain many follicles of various sizes), isosexual precocious puberty and delayed skeletal growth. A series of ten children with Van Wyk Grumbach syndrome is been presented with their clinical features, biochemical and radiological profile and management. Patients showed a noteworthy improvement upon thyroxine therapy. It is vital to keep this entity in consideration and; hence, should investigate for thyroid status during the evaluation of ovarian cysts. Thyroxin replacement after establishing the diagnosis early can prevent the patient from going through extensive workup and surgeries. Key Words: Hypothyrodism, Multicystic ovaries, Isosexual precocious puberty.

Perceptions of health professionals regarding minimally invasive tissue sampling (MITS) to identify the cause of death in stillbirths and neonates: results from a qualitative study.

BACKGROUND: Pakistan is considered to be one of the riskiest places in the world for childbirth as measured by its high stillbirth and neonatal mortality rates. Complete diagnostic autopsy remains the gold standard to determine the cause of death (CoD); however, it is not routinely implemented due to religious objections, sociocultural beliefs, limited resources and low demand from physicians and families. Recently, minimally invasive tissue sampling (MITS) using needle biopsies of multiple tissues to obtain tissue for histological examination and organism identification with PCR has been developed and promoted to determine CoD in low-resource areas. To ensure successful implementation of MITS, it is important to understand health professionals' attitudes and perceptions related to MITS. METHODS: A qualitative study was conducted at the National Institute of Child Health (NICH), Karachi, Pakistan. Focus group discussions (FGDs) and Key-informant interviews (KIIs) were conducted with health professionals including doctors, nurses, trainees, clinicians, bioethics experts and public health experts to explore their perceptions and views on acceptability of MITS. Data were analyzed using NVivo 10 software. RESULTS: A total of 12 interviews (FGDs = 4; KIIs = 8) were conducted. Four overarching themes were identified: (I) acceptability of MITS; (II) perceived benefits of the MITS procedure; (III) factors facilitating the implementation of MITS; and (IV) health system requirements for implementing the MITS procedure. Generally, MITS was considered as a positive development for the health system. Diagnostic accuracy and identification of less common causes of death were highlighted as two main benefits of the MITS procedure. The study highlighted a number of facilitators for the acceptability of MITS including effective counseling, building trust with parents, fast procedure time, and approaching families within a few hours of death. In addition, lack of skilled staff, poorly equipped healthcare facilities and the potential high cost to conduct MITS were identified as challenges for the implementation of MITS. CONCLUSIONS: This formative research provided a unique opportunity to explore health professionals' views and attitudes towards the MITS procedure. Such insights are crucial to ensure successful implementation and integration of a new technique into the existing health system. The research identified the factors influencing the acceptability of MITS among health professionals in Pakistan. The study also informed factors that could help facilitate the implementation of the MITS procedures in the context of Pakistan and similar settings.

Management of disorders of sex development - With a focus on development of the child and adolescent through the pubertal years.

Disorders of sex development, congenital conditions in which chromosomal, gonadal or anatomic sex is atypical at birth, require urgent assessment by a multidisciplinary team, to define whether there is a life threatening disorder of congenital adrenal hyperplasia or a healthy child with a complex condition. Uncertainty, stigma and taboo complicate counselling which must be knowledgeable, comprehensive and sensitive to different circumstances, religions and cultures. This articles will discuss clinical and genetic diagnosis, decisions regarding sex of rearing, ethical dilemmas, medical management of the infant and of the child or adolescent presenting for the first time with a DSD. Surgical options, timing and management are outlined.

Perceptions of parents and religious leaders regarding minimal invasive tissue sampling to identify the cause of death in stillbirths and neonates: results from a qualitative study.

BACKGROUND: Recently, the minimal invasive tissue sampling (MITS) procedure has been developed to support determination of the cause of death as an alternate to conventional autopsy, especially in countries where complete diagnostic autopsy is not routine. To assess the feasibility of implementation of the MITS procedure for a study to determine cause of death in premature births and stillbirths in south Asia, we explored the views and perceptions of parents and religious leaders on the acceptability of MITS. METHODS: A qualitative study was conducted at the National Institute of Child Health (NICH) hospital of Karachi, Pakistan. Focus group discussions (FGDs) were conducted with parents of newborns who visited well-baby clinics of the NICH hospital for post-natal check-ups. Key-informant interviews (KIIs) were conducted with religious leaders. Data were analyzed using NVivo 10 software. RESULTS: A total of 13 interviews (FGDs = 8; KIIs = 5) were conducted. Three overarching themes were identified: (I) acceptability of MITS; (II) concerns affecting the implementation of MITS; and (III) religious and cultural perspectives. Participants' acceptance of MITS was based on personal, religious, cultural and social beliefs. Parents widely recognized the need for this procedure in cases where the couple had experienced multiple stillbirths, neonatal deaths and miscarriages. Counseling of parents was considered vital to address emotional concerns of the parents and the family. Religious leaders indicated acceptability of the MITS procedure from a religious perspective and advised that respect for the deceased and consent of the guardians is mandatory when performing MITS. CONCLUSIONS: This qualitative study provided a unique opportunity to understand the views of parents and religious leaders towards the use of MITS. Generally, MITS appears to be an acceptable method for identifying the cause of death in neonates and stillbirths, provided that the deceased is respected and buried as soon as possible without any delays and parents are counseled appropriately. Findings from this research are essential in approaching families for consent for MITS.

Functional analysis of novel desert hedgehog gene variants improves the clinical interpretation of genomic data and provides a more accurate diagnosis for patients with 46,XY differences of sex development.

BACKGROUND: Desert hedgehog (DHH) gene variants are known to cause 46,XY differences/disorders of sex development (DSD). We have identified six patients with 46,XY DSD with seven novel DHH gene variants. Many of these variants were classified as variants of uncertain significance due to their heterozygosity or associated milder phenotype. To assess variant pathogenicity and to refine the spectrum of DSDs associated with this gene, we have carried out the first reported functional testing of DHH gene variant activity. METHODS: A cell co-culture method was used to assess DHH variant induction of Hedgehog signalling in cultured Leydig cells. Protein expression and subcellular localisation were also assessed for DHH variants using western blot and immunofluorescence. RESULTS: Our co-culture method provided a robust read-out of DHH gene variant activity, which correlated closely with patient phenotype severity. While biallelic DHH variants from patients with gonadal dysgenesis showed significant loss of activity, variants found as heterozygous in patients with milder phenotypes had no loss of activity when tested with a wild type allele. Taking these functional results into account improved clinical interpretation. CONCLUSION: Our findings suggest heterozygous DHH gene variants are unlikely to cause DSD, reaffirming that DHH is an autosomal recessive cause of 46,XY gonadal dysgenesis. Functional characterisation of novel DHH variants improves variant interpretation, leading to greater confidence in patient reporting and clinical management.
