RESUMEN

BACKGROUND: In order for low and middle income countries (LMIC) to transition to Human Papilloma Virus (HPV) test based cervical cancer screening, a greater understanding of how to implement these evidence based interventions (EBI) among vulnerable populations is needed. This paper documents outcomes of an implementation research on HPV screening among women from tribal, rural, urban slum settings in India. METHODS: A mixed-method, pragmatic, quasi-experimental trial design was used. HPV screening on self-collected cervical samples was offered to women aged 30-60 years. Implementation strategies were 1) Assessment of contextual factors using both qualitative and quantitative methods like key informant interviews (KII), focus group discussions (FGDs), pre-post population sample surveys, capacity assessment of participating departments 2) enhancing provider capacity through training workshops, access to HPV testing facility, colposcopy, thermal ablation/cryotherapy at the primary health care centers 3) community engagement, counselling for self-sampling and triage process by frontline health care workers (HCWs). Outcomes were assessed using the RE-AIM (Reach, Effectiveness, adoption, implementation, maintenance) framework. RESULTS: Screening rate in 8 months' of study was 31.0%, 26.7%, 32.9%, prevalence of oncogenic HPV was 12.1%, 3.1%, 5.5%, compliance to triage was 53.6%, 45.5%, 84.6% in tribal, urban slum, rural sites respectively. Pre-cancer among triage compliant HPV positive women was 13.6% in tribal, 4% in rural and 0% among urban slum women. Unique challenges faced in the tribal setting led to programme adaptations like increasing honoraria of community health workers for late-evening work and recalling HPV positive women for colposcopy by nurses, thermal ablation by gynaecologist at the outreach camp site. CONCLUSIONS: Self-collection of samples combined with HCW led community engagement activities, flexible triage processes and strengthening of health system showed an acceptable screening rate and better compliance to triage, highlighting the importance of identifying the barriers and developing strategies suitable for the setting. TRIAL REGISTRATION: CTRI/2021/09/036130.

RESUMEN

BACKGROUND: In vitro studies with human fetal islets of different gestational ages (GA) would be a great tool to generate information on the developmental process of the islets as this would help to recontextualize diabetes research and clinical practice. Pancreatic islets from human cadavers and other animal species are extensively researched to explore their suitability for islet transplantation procedure, one of the upcoming treatment strategies for insulin-dependent diabetes mellitus. Although human fetal islets are also considered for islet transplantation, ethical issues and limited knowledge constraints their use. The fetal islets could be explored to address the information lacunae on the maturity process of pancreatic islets and the endocrine-exocrine signaling mechanisms. AIM: This study aimed to assess the feasibility of isolating viable islets and study the cytoarchitecture of the fetal pancreas of GA 22-29 weeks, not reported otherwise. METHODOLOGY: Pancreas obtained from the aborted fetuses of GA 22-29 weeks were subjected to collagenase digestion and were further cultured to determine the viability in vitro. Parameters assessed were expression of markers for endocrine cell lineages and insulin release to glucose challenge. RESULTS: Islets were viable in vitro and islets were shown to maintain cues for post-digestion re-aggregation and expansion in culture. The immunofluorescent staining showed islets of varying sizes, homogenous cell clusters aggregating to form heterogenous cell clusters, otherwise not reported for this GA. On stimulation with different concentrations of glucose (2.8 and 28 mM), the fetal islets in the culture exhibited insulin release, and this response confirmed their viability in vitro. CONCLUSION: Our findings showed that viable islets could be isolated and cultured in vitro for further in-depth studies to explore their proliferative potential as well as for the identification of pancreatic progenitors, a good strategy to take forward.

RESUMEN

BACKGROUND: In view of the WHO's call for the elimination of cervical cancer as a public health problem, and current low screening coverage, Indian policy makers need evidence on how to effectively implement cervical screening programmes, ensuring equity in access. Our study will follow the INSPIRE implementation framework to co-design and test HPV-based screening approaches in two states of India with different health system organisation, based on understanding the status of screening as currently implemented, readiness and challenges to transition to HPV-based screening, and preferences of key stakeholders. Here, we describe our protocol for the formative phase of the study (SHE-CAN). METHODS: The study population includes women from vulnerable populations, defined as residents of tribal areas, rural villages, and urban slums, in the states of Mizoram and Tamil Nadu. The baseline assessment will use mixed methods research, with desktop reviews, qualitative studies, and surveys. A capacity assessment survey of screening and treatment facilities will be done, followed by interviews with healthcare providers, programme managers, and community health workers. Interviews will be conducted with previously screened women and focus group discussions with under and never-screened women and community members. Stakeholder workshops will be held in each state to co-design the approaches to delivering HPV-based screening among 30-49-year-old women. DISCUSSION: The quality and outcomes of existing screening services, readiness to transition to HPV-based screening, challenges in providing and participating in the cervical cancer care continuum, and acceptability of screening and treatment approaches will be examined. The knowledge gained about the current system, as well as recognition of actions to be taken, will inform a stakeholder workshop to co-design and evaluate implementation approaches for HPV-based screening through a cluster randomised implementation trial.

RESUMEN

Iron deficiency anemia is associated with maternal morbidity and poor pregnancy outcomes. Heme and non-heme iron transport proteins expressed in the placenta help in adequate iron supply from anemic mother to fetus. Here we examined the expression of placental iron trafficking molecules and their association with maternal and neonatal iron status in pregnant women with iron deficiency anemia (IDA). Pregnant women who received prenatal care at Christian Medical College, Vellore, India for childbirth were recruited. Pregnant women who were 18-35 years old with gestational age (GA) of ≥36 weeks were eligible to participate in the study. In a prospective cohort of pregnant women, 22 % were iron deficiency anemia and 42 % were iron replete. Samples were collected (Maternal blood, placental tissue, and cord blood) from pregnant women with a gestational age of ≥38 weeks at the time of delivery. The mean gestational age at the first visit and delivery was 12.8 ± 2.72 weeks and 39 ± 1.65 weeks, respectively. Hemoglobin (9.3 ± 0.9 g/dl) and ferritin (15.4(0.8-28.3) ng/ml) levels at delivery were significantly decreased in IDA as compared to controls. The fetal hemoglobin and ferritin levels were in the normal range in both groups. There was no correlation between maternal and cord blood hepcidin with fetal iron status in IDA. We further analyzed the expression of iron transport genes in the placenta of controls and the IDA group. Under maternal iron insufficiency, the expression of placental iron transporters DMT1, FPN1, and GDF15 was upregulated at the protein level. In IDA, placental GDF15 and ferroportin protein had an association with fetal iron status. These findings confirm that placental iron traffickers respond to maternal iron deficiency by increasing their expression and allowing sufficient iron to pass to the fetus.

RESUMEN

Objectives: The frequent association between malformations and chromosomal abnormalities is now well-established. This study looks at the incidence and type of chromosomal abnormalities detected by conventional cytogenetic analysis in women undergoing invasive tests following detection of fetal anomalies on antenatal scans as well as incidence of other genetic abnormalities detected by DNA analysis of fetuses with congenital anomalies that had a normal karyotype. Materials and Methods: A retrospective, observational study of pregnant women undergoing invasive testing following identification of fetal anomalies by ultrasonography was carried out in a tertiary care facility, Vellore, India, between 2011 and 2018. Results: 169 women underwent an invasive diagnostic procedure following detection of fetal anomalies. The most common indication for doing fetal karyotype was the presence of major fetal structural anomalies (142/169, 84%) with over a third (48/142, 34%) having multisystem involvement. Fetal hydrops was the next most common indication, detected in 18/169 (10%) fetuses. Aneuploidy was seen 19 of 25 fetuses (76%) with an abnormal karyotype with autosomal aneuploidy accounting for 13 (68%) and sex chromosome aneuploidy for seven (37%) of the fetuses. One fetus had double aneuploidy. In fetuses with normal karyotype, no additional information was obtained from further genetic testing. Conclusions: The overall detection rate of chromosomal abnormalities in our study using conventional cytogenetic analysis was 14.8%, the majority (72%) being associated with structural malformations, 20% with non-immune hydrops and 4% with soft markers. Abnormal karyotypes were seen in 12.7% of fetuses with structural malformations.

RESUMEN

Background: Globally, over 130 million babies are born every year, and almost 8 million die before their first birthday. Data on perinatal mortality (PM) and its various causes are lacking in many parts of the world including India. Objectives: This study aimed to estimate stillbirth (SB), early neonatal, and PM rates and its causes over the last decade in a rural development block, India. Materials and Methods: This is a nonconcurrent cohort study, analyzing the births, SBs, and early neonatal deaths between January 2008 and December 2017. The World Health Organization-PM classification was used to allocate causes of death as well as maternal risk factors. Birth weights were classified using standard growth charts. Results: There were 20,704 births after 28 weeks gestation and where the fetus weighed more than 1000 g of which 285 were SBs. There were 20,419 live births with 229 early neonatal deaths. There was a significant decline in PM rate from 32 per 1000 to 11 per 1000. There was a decrease in the small for gestational age fetuses from 20% to 12.5%. The main cause for SBs was antepartum hypoxia (34.4%) and fetal growth disorders (26.3%). Complications of intrapartum events contributed to 32.8% of the early neonatal deaths. Conclusion: Steady decline in PM rate and in the number of small for gestational age fetuses over 10 years was seen. Pregnancy registration and follow-up help in giving us a better understanding of the causes of PM.

RESUMEN

OBJECTIVE: To assess the effectiveness in preventing cesarean section for failed induction by using Foley catheter for cervical ripening in comparison to Foley catheter with a weight attached to it. METHODS: A randomized control trial conducted between November 2018 and July 2020, which looked at induction of labor with 30-ml Foley catheter in one arm and the Foley placed with a 500 ml weight attached to it in the other arm. Primary outcome was the cesarean section rate. RESULTS: We randomized 399 women. Modes of delivery were similar in both groups. Numbers undergoing cesarean section for failed induction were higher in the group that underwent induction with Foley with weight but this was not statistically significant (45.7% vs 26.5%, P = 0.1). There was a shorter time to expulsion of the Foley with weight attached (mean ± standard deviation: 2.6 ± 3.3 h vs 10.9 ± 3.2 h, P < 0.001) but this did not translate into a difference in time to active labor or time to delivery. CONCLUSION: Placing a weight at the end of the Foley catheter for induction of labor does not affect the time to delivery or the rate of cesarean deliveries, although there is faster expulsion of the Foley. CLINICAL TRIAL REGISTRATION NO: CTRI/2018/10/016154.

RESUMEN

BACKGROUND: India attributes to about 15% of the maternal mortality globally. Many a time poor maternal and neonatal outcomes occur unanticipated during intrapartum and postpartum period. An efficient referral system identifies the indications necessitating prompt referrals besides ensuring patient friendliness and continuity of care. METHODOLOGY: The descriptive, retrospective study was done in a secondary care hospital of a teaching institution in South India, run by primary care physicians, obstetricians and pediatricians. It describes the referrals from labour room in a year, identifying the referral rate, indications, maternal and neonatal outcomes. RESULTS: The referral rate was found to be 3 per cent. The most common indication for the referrals was hypertensive disorders of pregnancy (54.5 percent). Among the women referred, there were no maternal deaths and majority had uncomplicated postpartum period. Eleven women developed postpartum hemorrhage. Neonatal outcome reflected a good trend as 83 per cent had an uneventful hospital stay. There were eight early neonatal deaths. CONCLUSION: The hospital could reduce the referral load to its tertiary care due to adequate training of primary care post graduates in basic obstetrics and anaesthesia skills, establishing standardized referral protocol and monitoring with regular clinical audits. Patient experience could be improved with inter referral unit communication and linking the health information system.

RESUMEN

Congenital long QT syndrome [LQTS] is a channelopathy characterized by QT prolongation and polymorphic VT. LQTS however need not be a purely electrical disease. Defects in ion channels may cause myocardial architectural disruption leading to ventricular non compaction [VNC]. It is defined as the presence of prominent ventricular trabeculations and deep intertrabecular recesses within the endomyocardium. We describe the in-utero management of a foetus who was later found to have LQTS with VNC. The detection of ventricular tachycardia and complete heart block in utero should arouse the suspicion of LQTS. It would be wise to avoid QT prolonging antiarrhythmics in this subset of patients.

RESUMEN

BACKGROUND: Early detection of breast and cervical cancer by organized screening has been found to reduce mortality rates in trials, but documentation of programme results and challenges is rarely done from non-trial settings. This study reports results of a population-based cancer control programme in a rural block in Vellore, Tamil Nadu, population size (116,085), targeting a population of 18,490 women aged 25-60 years, between November 2014 and March 2018. METHODS: Village-based health education sessions were conducted by social workers, using trained volunteers and health workers to motivate eligible women. Screening was done at a secondary level hospital, by trained general physicians using visual inspection with acetic acid and clinical breast examination, followed by colposcopy, radiological imaging (breast) and biopsy as required. RESULTS: A total of 8 volunteers and 17 health workers motivated women for 93 health education and screening sessions, in 46 out of 82 villages. While 1,890/18,490 (10.2 per cent) were screened for breast cancer, 1,783 (9.6 per cent) were screened for cervical cancer, with a yield of 3.4/1,000 for cervical pre-cancer/cancer. The main challenges were creating time for screening activities in a busy secondary hospital and difficulty in ensuring treatment completion of screen-detected cases. CONCLUSIONS: Population-based cancer screening programs can be offered by secondary hospitals that also run primary care services, to increase screening rates. Clear referral systems need to be established, bearing in mind that social factors, especially poor family support, may pose a threat to treatment, in spite of easy availability of cure.

RESUMEN

Objective: Breech presentation is the most common fetal malpresentation at term, with an incidence of 3-4%. External cephalic version (ECV) is a procedure that can be offered to women with breech presentation beyond 36 weeks of gestation to convert it to cephalic presentation, reducing the risks of a vaginal breech delivery and the morbidities associated with caesarean section. Material and Methods: We retrospectively reviewed the records of women who underwent ECV between October 2012 and June 2020 with the objectives of determining the success rate of the procedure, the mode of delivery, the maternal and neonatal outcomes, periprocedural complications and their management. Results: Among the 200 women who underwent the procedure with a 64% success rate (128 women), there were 110 vaginal deliveries (56.7%) including five vaginal breech deliveries, and 84 women (43.2%) underwent caesarean section, which included 24 women who had successful ECV but needed emergency caesarean for other indications. There was no significant difference in the neonatal APGAR scores in those who had a successful ECV and those who did not. Only three women (1.5%) experienced any significant periprocedural complication. Conclusion: These results suggest that ECV improves the possibility of a vaginal delivery with an overall low complication rate, reducing the neonatal risks associated with vaginal breech delivery and the maternal morbidity of a caesarean section. It may thus contribute to reducing the primary caesarean section rate, making it a useful intervention, especially in limited resource settings.

RESUMEN

INTRODUCTION: Vitamin B12 is essential for the normal functioning of the nervous system and for the formation of red blood cells. Vegetarian diet, low socioeconomic status, and social and religious reasons are known risk factors of its deficiency. Pregnant women, children, and the elderly are vulnerable groups. Indians have the highest prevalence, but the data among pregnant women in the rural setting is lacking. OBJECTIVES: The objective of this study is to assess the prevalence of Vitamin B12 deficiency and its associated factors among pregnant women of rural South India. MATERIALS AND METHODS: A cross-sectional study was conducted to recruit consecutive 120 multigravida women with ≤20 weeks of gestation, attending the mobile doctor run clinic of Kaniyambadi block, Vellore. A structured questionnaire was administered, and blood samples were collected. RESULTS: The prevalence of Vitamin B12 deficiency (<200 pgm/ml) and anemia (Hb ≤10.5 g/dL) was 55% and 17.5%, respectively. Only 11.7% were B12 deficient and anemic. Past history of abortion (odds ratio [OR] = 0.5), fatigue (OR = 0.4), and low B12 intake (OR = 2) was associated only in the bivariate analysis. First trimester (OR = 3.9) and obesity (OR = 9.6) were found to be independent risk factors of Vitamin B12 deficiency. CONCLUSION: Our study showed a high prevalence of Vitamin B12 deficiency in pregnancy in rural India. Some risk factors were identified. However, studies with a higher sample size will be beneficial to study the associated risk factors better.

RESUMEN

CONTEXT: Domestic violence in Indian setting has five major components: emotional abuse; physical violence; sexual violence; honor killing; dowry-related abuse; and death. AIMS: The aim of the study was to estimate the prevalence of domestic violence and 3 of its components - emotional abuse, physical violence, and sexual violence among women in the age group of 15-49 years in Kaniyambadi block, rural Vellore, Tamil Nadu and to determine the risk factors of domestic violence. SETTINGS AND DESIGN: A community-based cross-sectional study among women between the ages 15 and 49 years at the rural setting of Kaniyambadi block, Tamil Nadu. RESULTS: Prevalence of all forms of domestic violence among women was 77.5%, and forty percent women were classified as having ever been subjected to severe domestic violence. Prevalence of physical violence was 65.8%, sexual abuse was 17.5%, and emotional abuse was 54.2%. Alcohol consumption by husband (adjusted odds ratio [AOR] 4.37; 1.35, 14.18), controlling behavior by family member (AOR 8.07; 2.47, 26.37), and woman's employment (AOR 4.33; 1.27, 14.77) were statistically significant determinants of domestic violence. Three-fourth (73.1%) of the women felt that being subjected to domestic violence has affected their physical and mental health. CONCLUSIONS: The high prevalence of domestic violence in our community needs to be addressed as it has tacit implications on socioeconomic well-being, physical and mental health of a woman, her family, and thereby, society as a whole.

RESUMEN

BACKGROUND AND OBJECTIVES: Gestational Diabetes Mellitus (GDM) has been well documented to be associated with significant mortality and morbidity among both mother and their offspring. Prevalence of GDM in India varies between regions and has been documented to be on the rise over the last two decades which is a public health concern and reflects an increase in the frequency of type 2 diabetes mellitus in these populations. This study aimed at estimating the prevalence of GDM among antenatal women attending a rural secondary care hospital in southern India and attempts to study associations between anthropometry, parental history, physical activity of pregnant women and GDM. METHODS: A hospital based cross sectional study was done among 630 pregnant women who were screened with oral glucose tolerance test between 24 and 28 weeks of gestation based on IADPSG criteria. Risk factors for developing GDM were assessed by conducting home visits to 75 women diagnosed to have GDM and 150 randomly selected women without GDM. RESULTS: Hospital based prevalence of GDM was 14% (95 % CI: 11.3% to 16.7%) and a significant rise in prevalence levels was noted with age. Women with family history of diabetes mellitus, women with body fat of more than 23% had 2.65 and 2.89 times significantly higher odds of developing GDM. Interpretation and conclusion: Family history of diabetes and excess body fat are risk factors associated with GDM. Among them excess body fat could be an independent risk factor without the influence of foetal weight and preventive measures could be directed towards it.

RESUMEN

BACKGROUND: India, with its large number of migrant workers, had a large number of people affected by HIV. This included antenatal women who are a vulnerable population. The Government of India along with nongovernmental organizations worked on a large number of programs to screen and decrease mother-to-child transmission. This in turn has brought down the prevalence of HIV. MATERIALS AND METHODS: Retrospective analysis of data from the block being provided with healthcare was carried out over a period of 14 years from January 2002 to December 2016. RESULTS: The observed HIV prevalence was 5.9 per 1000 in 2002 and showed a declining trend to 1.2 per 1000 in 2016. CONCLUSION: Consistent work at health education and preventive methods has helped bring down the prevalence of HIV over the years.

RESUMEN

BACKGROUND: Carcinosarcoma is a rare malignancy, and reports are often mixed along with other sarcomas. The literature on uterine carcinosarcoma per se is sparse. AIMS: This study aims to evaluate the demography, survival, and optimal treatment strategy of uterine carcinosarcoma. SETTINGS AND DESIGN: A tertiary care center in India. The study design was descriptive with survival analysis. MATERIALS AND METHODS: The medical records of all 18 patients admitted with uterine carcinosarcoma between January 2011 and December 2015 were reviewed. Baseline characteristics and outcomes were studied. Survival analysis was done using the Kaplan-Meier method and compared between treatment groups using the Log-rank test. RESULTS: The total number of uterine malignancies operated in our center over this time period was 311 of which 18 were carcinosarcomas (5.7%). Median age of presentation was 61 years (36-77 years). Most women (94%) were postmenopausal and 67% of them presented with postmenopausal bleeding. Over half of the patients (56%) presented late (Stage III or IV). Only 11 (61%) had adjuvant treatment and 7 patients had expired at the time of follow-up. The median survival was 284 days (95% confidence interval 107-461). Patients who received adjuvant therapy did better compared to those who did not (P = 0.036). CONCLUSIONS: Carcinosarcomas are aggressive tumors of postmenopausal women who present with bleeding or discharge per vaginum. In spite of adequate surgical staging followed by adjuvant therapy, survival remains poor. Improvements in early detection and optimal therapy need to be made.

RESUMEN

Mesenchymal stem cells (MSCs) are derived from Wharton's jelly tissue of the human umbilical cord. Given appropriate culture conditions, these cells can self-renew and differentiate into multiple cell types across the lineages. Among the properties exhibited by these cells, immunomodulation through secretion of trophic factors has been widely exploited in a broad spectrum of preclinical/clinical regenerative applications. Moreover, the extracellular matrix is found to play a major role apart from niche cells in determining stem cell fate including that of MSCs. Therefore, the currently employed technique of two-dimensional culture expansion can alter the inherent properties of naïve MSCs originally residing within the three-dimensional space. This limitation can be overcome to some extent by using native extracellular matrix scaffold culture system which mimics the in situ microenvironment. In this chapter, we have elucidated the protocol for the preparation of a native extracellular matrix scaffold by decellularization of the MSC sheet and thereof culture expansion and characterization of human Wharton's jelly-derived MSCs.

RESUMEN

OBJECTIVE: To study the prevalence and types of congenital anomalies that present at birth in a secondary-level hospital in South India and its contribution to perinatal mortality. MATERIALS AND METHODS: A total of 36,074 births over 10 years, from 2003 to 2013, were studied for the prevalence of gross congenital malformations at birth. It was a descriptive, cross-sectional study using data from the birth register and available medical records. RESULTS: The incidence of birth defects was 12.5 per 1000 live births, with musculoskeletal disorders being the commonest, followed by craniovertebral anomalies. The prevalence of anomalies over the past 10 years has not shown any significant change (p= 0.555). DISCUSSION: The high prevalence of neural tube defects indicates the need for periconceptional folic acid supplementation and early detection of anomalies, which would help in timely management. Detection of musculoskeletal anomalies would help in counseling patients antenatally.

RESUMEN

BACKGROUND: During delivery, drugs being prescribed cause concerns due to their harmful effects on lactation as well as potential adverse reactions on the mother. This retrospective study was performed to evaluate the drug prescribing pattern during normal delivery in a secondary care hospital in India. MATERIALS AND METHODS: This cross-sectional retrospective study included 3 months of patient's medical records. RESULTS: A total of 2222 drugs, comprising 51 different types of drugs were prescribed to 313 mothers undergoing normal delivery. Most of these drugs are safe in lactation. Ten types of drugs would have been better avoided, but they possibly did not cause harm because of their limited short-term use only during the intranatal period. CONCLUSION: This study reflects a good, safe, and rational medication practice during normal delivery for various common ailments in a secondary care hospital and can be cited as an example for similar settings.
