Multi-task transfer learning for the prediction of entity modifiers in clinical text: application to opioid use disorder case detection.

BACKGROUND: The semantics of entities extracted from a clinical text can be dramatically altered by modifiers, including entity negation, uncertainty, conditionality, severity, and subject. Existing models for determining modifiers of clinical entities involve regular expression or features weights that are trained independently for each modifier. METHODS: We develop and evaluate a multi-task transformer architecture design where modifiers are learned and predicted jointly using the publicly available SemEval 2015 Task 14 corpus and a new Opioid Use Disorder (OUD) data set that contains modifiers shared with SemEval as well as novel modifiers specific for OUD. We evaluate the effectiveness of our multi-task learning approach versus previously published systems and assess the feasibility of transfer learning for clinical entity modifiers when only a portion of clinical modifiers are shared. RESULTS: Our approach achieved state-of-the-art results on the ShARe corpus from SemEval 2015 Task 14, showing an increase of 1.1% on weighted accuracy, 1.7% on unweighted accuracy, and 10% on micro F1 scores. CONCLUSIONS: We show that learned weights from our shared model can be effectively transferred to a new partially matched data set, validating the use of transfer learning for clinical text modifiers.

Significance of platelet parameters in invasive squamous cell carcinoma of uterine cervix.

BACKGROUND: Cervical cancer is the second most common cancer among females worldwide. The role of platelets in cancer progression and metastasis have been evaluated in various cancers. This study is done to assess the association between platelet parameters and invasive squamous cell carcinoma of the cervix. MATERIALS AND METHODS: Eighty cases of squamous cell carcinoma of the cervix were retrospectively collected from the medical record department. Values of platelet parameters such as platelet count, mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT), platelet-large cell ratio (P-LCR), platelet-lymphocyte ratio (PLR), platelet-neutrophil ratio (PNR), and platelet-monocyte ratio (PMR) are collected from automated hematology analyzer. These values were compared with 80 healthy controls which were randomly selected. Values of platelet parameters were also compared among Federation Internationale de Gynecolgie et d'Obstetrique (FIGO) stages in 80 cases. RESULT: Mean ± standard deviation (SD) for platelet count, MPV, PDW, PCT, P-LCR, PLR, PNR, and PMR among cases were 316 ± 100.37 × 109/L, 9.98 ± 0.96, 11.11 ± 2.27, 0.31 ± 0.092, 24.09 ± 7.62, 179.35 ± 85.53, 63.89 ± 42.10, and 492.29 ± 192.86, respectively, and in controls were 300.30 ± 79.40 × 109/L, 9.97 ± 0.83, 10.97 ± 1.80, 0.59 ± 2.65, 23.94 ± 6.81, 137.72 ± 50.52, 60.07 ± 26.68, and 563.65 ± 602.55, respectively. The PLR between cases and controls was statistically significant. The platelet count and PCT between stages was statistically significant wherein the values increased from stage II to stage IV. CONCLUSION: Platelet parameters are importance in cervical cancer. PLR, platelet count, and PCT are platelet parameters that can be used as predictors and prognostic parameters in cervical cancer. These parameters are cost-effective and can be considered in low resource settings. However, a multicentric study with a larger sample size should be done to extrapolate the findings for patient care.

Semantically oriented EHR navigation with a patient specific knowledge base and a clinical context ontology.

Widespread adoption of electronic health records (EHR) in the U.S. has been followed by unintended consequences, overexposing clinicians to widely reported EHR limitations. As an attempt to fixing the EHR, we propose the use of a clinical context ontology (CCO), applied to turn implicit contextual statements into formally represented data in the form of concept-relationship-concept tuples. These tuples form what we call a patient specific knowledge base (PSKB), a collection of formally defined tuples containing facts about the patient's care context. We report the process to create a CCO, which guides annotation of structured and narrative patient data to produce a PSKB. We also present an application of our PSKB using real patient data displayed on a semantically oriented patient summary to improve EHR navigation. Our approach can potentially save precious time spent by clinicians using today's EHRs, by showing a chronological view of the patient's record along with contextual statements needed for care decisions with minimum effort. We propose several other applications of a PSKB to improve multiple EHR functions to guide future research.

Significance of platelet parameters in squamous cell carcinoma of oral cavity - A case-control study.

Introduction: Tumor microenvironment plays an important role in cancer progression. Platelets are one of the components of the tumor environment shown to have a role in cancer survival and progression. Materials and Methods: Ninety-six cases of squamous cell carcinoma (SCC) cases of the oral cavity and 96 age/sex-matched healthy controls were considered for the study. Data regarding platelet count, platelet distribution width (PDW), mean platelet volume (MPV), Platelet-Large Cell Ratio (P-LCR), Plateletcrit (PCT), platelet/neutrophil ratio (PNR), platelet/lymphocyte ratio (PLR), and Platelet/Monocyte Ratio (PNR) from automated hematology analyzer records and clinicopathological data from the Department of Pathology were captured. These data were compared between cases and controls and also with tumor size, tumor grade, lymph node status, and tumour node metastasis (TNM) stage of cases. Results: Mean ± standard deviation for platelet count, PDW, MPV, P-LCR, PCT, PNR, PLR and PMR among cases were 315.03 ± 98.26, 10.94 ± 1.66, 9.91 ± 0.77, 23.52 ± 5.64, 0.31 ± 0.086, 62.55 ± 31.51, 149.34 ± 61.32, and 498.67 ± 194.91, respectively, and among controls were 287.88 ± 74.11, 10.84 ± 1.18, 9.89 ± 0.72, 23.45 ± 4.55, 0.29 ± 0.061, 60.27 ± 21.02, 138.71 ± 49.28, and 497.64 ± 172.28, respectively. The association between means of platelet count, PDW, P-LCR, and PCT among cases and controls were statistically significant (P = 0.020, 0.006, 0.030, and 0.000, respectively). No statistically significant association was found between means of platelet count, PDW, MPV, P-LCR, PCT, PNR, PLR, and PMR versus tumor size, lymph node status, and tumor grades. The association between the means of PCT/PMR and TNM Stages I and II were statistically significant (P = 0.029 and 0.016, respectively). Conclusions: Platelet count, morphology, and functions are altered in oral SCC. Platelet activation plays an important role in oral cancer. PCT and PMR can be used to predict the progress of oral SCC as a cost-effective inflammatory marker.

Observational study of feasibility and acceptability of the levonorgestrel-releasing intrauterine device as a long-acting reversible contraceptive in a primary care setting in India.

Objectives: The levonorgestrel-releasing intrauterine device (LNG-IUD) is a well-accepted contraceptive across developed countries, yet there is limited experience in use and acceptance amongst women living in low-resource, developing country settings. We studied the feasibility of providing the LNG-IUD through a primary care service, and its acceptability amongst women living in a low-income, rural-tribal community in India. Study design: We conducted an observational study of feasibility and acceptability at four health facilities (three rural, and one urban) in Rajasthan, India. Women seeking contraception were offered the LNG-IUD in addition to existing contraceptive methods. We followed all those who adopted LNG-IUD from August 2015 to September 2019 (n= 1266) till discontinuation or 12 months, whichever was earlier. The primary outcome was continuation rate and acceptability, and the secondary outcome was change in hemoglobin levels, which we measured before insertion and at 12-month follow-up, using Sahli's method. Results: Most users lived in villages, were illiterate, belonged to marginalized groups, had 2 or more children, and wished to limit births when they adopted the method. The 12-month continuation rate was 87.6%. Amongst all users, 7.4% of women sought removal for side effects and 2% for change in reproductive intention, while another 2% reported spontaneous expulsion. Most continuing users reported hypomenorrhea (54%) or amenorrhea (42%) by 12 months of use. User satisfaction was high at 91.6%, with 92% of women rating their experience as equaling or exceeding expectations. Moderate and severe anemia reduced, and mean hemoglobin levels increased by 0.7 g/dL (p < 0.01). Conclusion: Primary care clinics can feasibly deliver LNG-IUD, with high acceptability amongst women living in low resource settings. Given the paucity of long-acting reversible contraceptive options and high prevalence of anemia among women in India and similar countries, the method should be piloted through the public health system. Implications: Long duration of contraceptive action, ability to reduce menstrual bleeding and reduce anemia, reversibility, and easy removal, combine to make LNG-IUD acceptable to women, especially in regions with high prevalence of anemia. This study demonstrates the feasibility and acceptability of introducing LNG-IUD in a low resource, primary care setting.

Understanding the Socio-Economic Vulnerability in Child Malnutrition Between Migrants and Non-Migrants Children (12-59 Months) in India: Evidence from a Cross-Sectional Study.

India has witnessed increasing trends in internal migration over the last three decades. In India, migrant children are not a homogeneous group and their reasons for movement and vulnerabilities vary across socio-economic stratum. For some children, migration may open possibilities and is associated with expanding social and economic spheres, but for many others, it may bring serious risks. Therefore, the study has been carried out to understand socio-economic vulnerability in child nutrition with migration status and other contributing factors in India. This study used data from the National Family Health Survey, the fourth in the NFHS series which was conducted in 2015-2016 (NFHS-4). We were interested in looking at the children age 12-59 months for their nutritional indicators such as stunting and underweight across migrants and non-migrants children. This resulted in a sample of 199,448 children in selected age group and among them 33.1% children belongs to the migrant family as compared to 67% of non-migrant children. Overall, 44.2% of children were stunted and 39.5% were underweight among non-migrant children as compared to 37.4% & 32.8% of migrant children were stunted and underweight respectively. Further, the results showed that among the social groups, scheduled caste children were found a high variation in underweight (34% vs. 41.6%) and stunting (36% vs. 46%) between migrants and non-migrants children. Similar trend of malnourishment is found in the poor wealth quintile, for rural residents and low educated women with non-migrant status. Those children who were poor but non-migrant were more likely to be malnourished as underweight [aOR; 1.15, CI: 1.11-1.18] and stunted [aOR; 1.17, CI:1.13-1.20] as compared to migrant status children in the same category of the household. Similarly in reference to scheduled caste migrant group, the scheduled caste non-migrant were more likely to be underweight [aOR; 1.15, CI: 1.09-1.20] and stunted [aOR; 1.18, CI: 1.12-1.23] than the children with migrant status. There were huge differences between migrant and non-migrant children in nutritional statuses. Education, caste and wealth index are found to be an important variables to explain the differential between migrants and non-migrants in child's nutritional aspects. Children associated with poor socio-economic vulnerability and non-migrant category need to be taken care of more and a community targeted approach is required to understand the gaps. The programs such as ICDS, and Poshan Abhiyan need to be revamped adding the migration aspect of the families and children in terms of their health and nutritional aspects.

Understanding Frailty, Functional Health and Disability among Older Persons in India: A Decomposition Analysis of Gender and Place of Resident.

BACKGROUND: We estimated and compared the differences in frailty, disability, and functional limitation among men and women, and among urban and rural dwellers. Further, this study also provides the analysis of key factors influencing frailty, functional limitation and disability among older persons in India. STUDY DESIGN: Two cross-sectional surveys. METHODS: WHO-SAGE (2007-10) and BKPAI-2011 (Building Knowledgebase for Population Ageing in India) (2007-10) were used. Oaxaca decomposition method was used to decompose the gender and place of resident differentials. Statistical software RStudio (Version 1.2.1335) was used to perform these analyses RESULTS: The decomposition model was able to explain 46.5%, 41.6% and 46.4% of the difference between frailty, functional limitation and disability among older persons respectively. The key factors, which significantly (P<0.05) explained the gap for both frailty and functional limitation, were Education (0.009 &1.24), working status (0.018 & 1.93), physical activity (0.001 & 0.15) and migration (0.018 & 1.98). Higher educational attainment (0.008 & 1.10) and wealth quintile (0.009 & 1.18) in urban areas might be a factors resulting in the lowering of frailty and functional limitations. CONCLUSION: The poorer functional health among older women can largely be explained by gender differentials in socioeconomic status and consequent empowerment (such as less control of their mobility and financial independence). This implies that efforts to improve gender disadvantages in earlier life stages might get reflected in better health for females in older age.

Costing and Cost-Effectiveness of a Mobile Health Intervention (ImTeCHO) in Improving Infant Mortality in Tribal Areas of Gujarat, India: Cluster Randomized Controlled Trial.

BACKGROUND: During 2013, a mobile health (mHealth) program, Innovative Mobile Technology for Community Health Operation (ImTeCHO), was launched in predominantly tribal and rural communities of Gujarat, India. ImTeCHO was developed as a job aid for Accredited Social Health Activists (ASHAs) and staff of primary health centers to increase coverage of maternal, neonatal, and child health care. OBJECTIVE: In this study, we assessed the incremental cost per life-years saved as a result of the ImTeCHO intervention as compared to routine maternal, neonatal, and child health care programs. METHODS: A two-arm, parallel, stratified cluster randomized trial with 11 clusters (primary health centers) randomly allocated to the intervention (280 ASHAs, n=2,34,134) and control (281 ASHAs, n=2,42,809) arms was initiated in 2015 in a predominantly tribal and rural community of Gujarat. A system of surveillance assessed all live births and infant deaths in the intervention and control areas. All costs, including those required during the start-up and implementation phases, were estimated from a program perspective. Incremental cost-effectiveness ratios were estimated by dividing the incremental cost of the intervention with the number of deaths averted to estimate the cost per infant death averted. This was further analyzed to estimate the cost per life-years saved for the purpose of comparability. Sensitivity analysis was undertaken to account for parameter uncertainties. RESULTS: Out of a total of 5754 live births (3014 in the intervention arm, 2740 in the control arm) reported in the study area, per protocol analysis showed that the implementation of ImTeCHO resulted in saving 11 infant deaths per 1000 live births in the study area at an annual incremental cost of US $163,841, which is equivalent to US $54,360 per 1000 live births. Overall, ImTeCHO is a cost-effective intervention from a program perspective at an incremental cost of US $74 per life-years saved or US $5057 per death averted. In a realistic environment with district scale-up, the program is expected to become even more cost-effective. CONCLUSIONS: Overall, the findings of our study strongly suggest that the mHealth intervention as part of the ImTeCHO program is cost-effective and should be considered for replication elsewhere in India.

Deaths during pregnancy, childbirth and puerperium: Exploring causes, context and evidence from Eastern India.

AIM: The study was aimed to identify the specific reasons and circumstances of maternal deaths in West Bengal. METHODS: The present study is a retrospective study of 317 maternal deaths, conducted between November 2013 and October 2015 at two major referral hospitals of eastern India, West Bengal. The frequencies, proportions, measures of central tendency and dispersion were used to describe the data. The data were analyzed using the statistical software spss version 20.0. ArcGIS 10.1 was also employed to show the distributional pattern of maternal deaths. RESULTS: The overall maternal mortality ratio was estimated as 561 per 100 000 live births. Eclampsia or hypertensive disorders of pregnancy contributed to one-third (33.1%, n = 105/317) of maternal deaths. The maternal deaths were more common (41%) among women belonging to the age group of 20-24 years and primiparous (36.9%) group. The average distance for traveling to reach the final hospital was 47.37 km. Approximately, three-fourths (72.2%) of maternal deaths were in the post-partum period. Half of the women (50.5%) sought medical care after 12 hrs of developing complications. The majority of the cases (80.1%) were referred and about 45% of patients had a cesarean section. CONCLUSION: The result suggests there was a shift in causes of maternal deaths from hemorrhage to eclampsia. Establishment of separate eclampsia units at lower-level health facilities may be a more plausible pathway to prevent eclampsia-related maternal deaths in West Bengal.

mHealth intervention "ImTeCHO" to improve delivery of maternal, neonatal, and child care services-A cluster-randomized trial in tribal areas of Gujarat, India.

BACKGROUND: The coverage of community-based maternal, neonatal, and child health (MNCH) services remains low, especially in hard-to-reach areas. We evaluated the effectiveness of a mobile-phone-and web-based application, Innovative Mobile-phone Technology for Community Health Operations (ImTeCHO), as a job aid to the government's Accredited Social Health Activists (ASHAs) and Primary Health Center (PHC) staff to improve coverage of MNCH services in rural tribal communities of Gujarat, India. METHODS AND FINDINGS: This open cluster-randomized trial was conducted in 22 PHCs in six tribal blocks of Bharuch and Narmada districts in India. The ImTeCHO mobile-phone-and web-based application included various technology-based job aids to facilitate scheduling of home visits, screening for complications, counseling during home visits, and supportive supervision by PHC staff. Primary outcome indicators were a composite index calculated based on coverage of important MNCH services and coverage of at least two home visitations by ASHA within the first week of birth. Primary analysis was intention to treat (ITT). Generalized Estimating Equation (GEE) was used to account for clustering. Eleven PHCs each were randomly allocated to the intervention (280 ASHAs, population: 234,134) and control (281 ASHAs, population: 242,809) arms. The intervention was implemented from February, 2016 to January, 2017. At the end of the implementation, 6,493 mothers were surveyed. Most of the surveyed women were tribal (5,571, 85.8%), and reported having a government-issued certificate for living below poverty line (4,916, 75.7%). The coverage of at least two home visits within first week of birth was 32.4% in the intervention clusters compared to 22.9% in the control clusters (adjusted effect size 10.2 [95% CI: 6.4, 14.0], p < 0.001). Mean number of home visits within first week of birth was 1.11 and 0.80 for intervention and control clusters, respectively (adjusted effect size 0.34 [95% CI: 0.23, 0.45], p < 0.001). The composite coverage index was 43.0% in the intervention clusters compared to 38.5% (adjusted effect size 4.9 [95% CI: 0.2, 9.5], p = 0.03) in the control clusters. There were substantial improvements in coverage home visits by ASHAs during antenatal period (adjusted effect size 15.7 [95% CI: 11.0, 20.4], p < 0.001), postnatal period (adjusted effect size 6.4, [95% CI: 3.2, 9.6], p <0.001), early initiation of breastfeeding (adjusted effect size 7.8 [95% CI: 4.2, 11.4], p < 0.001), and exclusive breastfeeding (adjusted effect size 13.4 [95% CI: 8.9, 17.9], p < 0.001). Number of infant and neonatal deaths was similar in the two arms in the ITT analysis. The limitations of the study include potential risk of inaccuracies in reporting events that occurred during pregnancy by the mothers and the duration of intervention being 12 months, which might be considered short. CONCLUSIONS: In this study, we found that use of ImTeCHO mobile- and web-based application as a job aid by government ASHAs and PHC staff improved coverage and quality of MNCH services in hard-to-reach areas. Supportive supervision, change management, and timely resolution of technology-related issues were critical implementation considerations to ensure adherence to the intervention. TRIAL REGISTRATION: Study was registered at the Clinical Trial Registry of India (www.ctri.nic.in). Trial number: CTRI/2015/06/005847. The trial was registered (prospective) on 3 June, 2015. First enrollment was done on 26 August, 2015.

Praying until death: revisiting three delays model to contextualize the socio-cultural factors associated with maternal deaths in a region with high prevalence of eclampsia in India.

BACKGROUND: A disproportionately high proportion of maternal deaths (99 percent) in the world occur in low and middle income countries, of which 90 percent is contributed by Sub-Saharan Africa and South Asia. This study uses the effective "Three Delays" model to assess the socio-cultural barriers associated with maternal mortality in West Bengal, India. METHODS: It was a retrospective mixed methods study, which used facility-based as well as community-based approaches to explore factors associated with maternal deaths. We reviewed 317 maternal death cases wherein a verbal autopsy technique was applied on 40 cases. The Chi-square test (χ2) and multivariable logistic regression model were employed to accomplish the study objectives. RESULTS: The delay in seeking care (Type 1 delay) was the most significant contributor to maternal deaths (48.6 percent, 154/317). The second major impacting contributor to maternal deaths was the delay in reaching first level health facility (Type 2 delay) (33.8 percent, 107/317), while delay in receiving adequate care at the health facility (Type 3 delay) had a role in 18.9 percent maternal deaths. Women staying at long distance from the health facilities have reported [AOR with 95 % CI; 1.7 (1.11-1.96)] higher type 2 delay as compared to their counterparts. The study also exhibited that the women belonged to Muslim community were 2.5 times and 1.6 times more likely to experience type 1 and 2 delays respectively than Hindu women. The verbal autopsies revealed that the type 1 delay is attributed to the underestimation of the gravity of the complications, cultural belief and customs. Recognition of danger signs, knowledge and attitude towards seeking medical care, arranging transport and financial constraints were the main barriers of delay in seeking care and reaching facility. CONCLUSIONS: The study found that the type-1 and type-2 delays were major contributors of maternal deaths in the study region. Therefore, to prevent the maternal deaths effectively, action will be required in areas like strengthening the functionality of referral networks, expand coverage of healthcare and raising awareness regarding maternal complications and danger signs.

Differential expression of miRNAs in acute myeloid leukemia quantified by Nextgen sequencing of whole blood samples.

New approaches are needed for understanding and treating acute myeloid leukemia (AML). MicroRNAs (miRs) are important regulators of gene expression in all cells and disruption of their normal expression can lead to changes in phenotype of a cell, in particular the emergence of a leukemic clone. We collected peripheral blood samples from 10 adult patients with newly diagnosed AML, prior to induction chemotherapy, and 9 controls. Two and a half ml of whole blood was collected in Paxgene RNA tubes. MiRNA was purified using RNeasy mini column (Qiagen). We sequenced approximately 1000 miRs from each of 10 AML patients and 9 controls. In subset analysis, patients with NPM1 and FLT3 mutations showed the greatest number of miRNAs (63) with expression levels that differed from control with adjusted p-value of 0.05 or less. Some of these miRs have been described previously in association with leukemia, but many are new. Our approach of global sequencing of miRs as opposed to microarray analysis removes the bias regarding which miRs to assay and has demonstrated discovery of new associations of miRs with AML. Another strength of our approach is that sequencing miRs is specific for the 5p or 3p strand of the gene, greatly narrowing the proposed target genes to study further. Our study provides new information about the molecular changes that lead to evolution of the leukemic clone and offers new possibilities for monitoring relapse and developing new treatment strategies.

Recurrent soft tissue inflammation, necrotizing fascitis or Sweet syndrome, diagnostic dilemma.

Necrotizing Sweet syndrome is a recently described entity that can pose significant challenges for management. Although necrotizing fasciitis can be rapidly fatal in the absence of prompt surgical management, necrotizing Sweet syndrome may actually be worsened by any surgical intervention. Authors want to emphasize and increase awareness of this rare presentation.

The role of an mHealth intervention in improving knowledge and skills of accredited social health activists in tribal areas of Gujarat, India: a nested study within an implementation research trial.

AIM: To evaluate the effectiveness of an mHealth intervention in improving knowledge and skills of accredited social health activists in improving maternal, newborn and child health care in India. METHODS: This was a nested cross-sectional study within a cluster randomised controlled trial. The intervention was a mobile phone application which has inbuilt health education videos, algorithms to diagnose complications and training tools to educate accredited social health activists. A total of 124 were randomly selected from the control (n = 61) and intervention (n = 63) arms of the larger study after six months of training in Bharuch and Narmada districts of Gujarat. RESULTS: The knowledge of accredited social health activists regarding pregnancy (OR: 2.51, CI: 1.12-5.64) and newborn complications (OR: 2.57, CI: 1.12-5.92) was significantly higher in the intervention arm compared to the control arm. The knowledge of complications during delivery (OR: 1.36, CI: 0.62-2.98) and the postpartum (OR: 1.06, CI: 0.48-2.33) period was similar in both groups. The activists from the intervention arm demonstrated better skills for measuring temperature (OR: 4.25, CI: 1.66-10.89) of newborns compared to the control group. CONCLUSION: The results suggest potential benefits of this mHealth intervention for improving knowledge and skills of accredited social health activists.

Analyzing the etiology behind mortality associated with antepartum, intrapartum, and post-partum cases in a tertiary care teaching hospital of West Bengal

OBJECTIVE: The study was undertaken to understand the causes and circumstances of maternal deaths in West Bengal. MATERIAL AND METHODS: One hundred ten maternal deaths were reported during the period December 2010 through June 2012 in the Maternity Ward of Medical College and Hospitals, West Bengal. These deaths were reviewed using a facility-based Maternal Death Review protocol. The number and percentages were calculated and binary logistic regression analysis was performed. RESULTS: The majority of the deaths occurred in the 20-24 years' age group, those with Hindu religion, in the first and second gravida, and the postpartum period. One third of mothers had cesarean sections. The majority (78.2%) of deaths were among referred cases. Eclampsia was the leading cause of maternal death (29.1%). Approximately half of the deceased women sought care after 10 hours of developing complications. More than one-third of maternal deaths were registered with type 1 delays. CONCLUSION: Our study demonstrates that maternal deaths occurred among young women, referred cases, with cesarean sections and type 1 delays. We recommend that imparting basic skills and improving awareness to the community about the danger signs of pregnancy could be an effective measure to detect maternal complications at an earlier stage.

Rates, indications, and outcomes of caesarean section deliveries: A comparison of tribal and non-tribal women in Gujarat, India.

BACKGROUND: Even though the caesarean section is an essential component of comprehensive obstetric and newborn care for reducing maternal and neonatal mortality, there is a lack of data regarding caesarean section rates, its determinants and health outcomes among tribal communities in India. OBJECTIVE: The aim of this study is to estimate and compare rates, determinants, indications and outcomes of caesarean section. The article provides an assessment on how the inequitable utilization can be addressed in a community-based hospital in tribal areas of Gujarat, India. METHOD: Prospectively collected data of deliveries (N = 19923) from April 2010 to March 2016 in Kasturba Maternity Hospital was used. The odds ratio of caesarean section was estimated for tribal and non-tribal women. Decomposition analysis was done to decompose the differences in the caesarean section rates between tribal and non-tribal women. RESULTS: The caesarean section rate was significantly lower among tribal compared to the non-tribal women (9.4% vs 15.6%, p-value < 0.01) respectively. The 60% of the differences in the rates of caesarean section between tribal and non-tribal women were unexplained. Within the explained variation, the previous caesarean accounted for 96% (p-value < 0.01) of the variation. Age of the mother, parity, previous caesarean and distance from the hospital were some of the important determinants of caesarean section rates. The most common indications of caesarean section were foetal distress (31.2%), previous caesarean section (23.9%), breech (16%) and prolonged labour (11.2%). There was no difference in case fatality rate (1.3% vs 1.4%, p-value = 0.90) and incidence of birth asphyxia (0.3% vs 0.6%, p-value = 0.26) comparing the tribal and non-tribal women. CONCLUSION: Similar to the prior evidences, we found higher caesarean rates among non-tribal compare to tribal women. However, the adverse outcomes were similar between tribal and non-tribal women for caesarean section deliveries.

The Risk of Hypertension and Other Chronic Diseases: Comparing Smokeless Tobacco with Smoking.

BACKGROUND: In the past, studies have compared smokeless tobacco and non-tobacco users for the risk of various chronic diseases. The differences in the risk of chronic diseases between smokeless tobacco user and smokers have not been explored. The objective of this study is to estimate the risk of chronic diseases among smokeless tobacco users compared to smokers. METHODS: The data were used from the Study on Global Ageing and Adult Health (SAGE) Wave-1, conducted in 2007-2008 in India. The study sample is the respondents who reported consuming any form of tobacco in last 1 month. The total sample size was 4,038 respondents. The odds ratio of chronic morbidities was estimated taking smokers as the reference category. RESULTS: The odds ratios for (self-reported) diabetes, asthma, and hypertension were not significant for smokeless tobacco user compared to smoked tobacco users. The odds ratio of chronic lung diseases (CLDs) was significantly lower among smokeless tobacco users compared to smoked tobacco users. The odds ratio of hypertension (measured) combined with low education and belonging to lowest wealth quintiles were not significant for smokeless tobacco users compared to smoked tobacco users. Duration of the use of smokeless tobacco and quantity of use was found to have no significant relation with risk of chronic diseases as compared to smoking. CONCLUSION: This study did not find the significantly higher risk of chronic morbidities except for CLD for smokeless tobacco users compared to smoked tobacco users. The study suggests that the use of any form of tobacco may have a similar risk of chronic diseases.

Sickle cell disease and pregnancy outcomes: a study of the community-based hospital in a tribal block of Gujarat, India.

BACKGROUND: Sickle cell disease (SCD) is a hereditary blood disorder prevalent in tribal regions of India. SCD can increase complications during pregnancy and in turn negatively influence pregnancy outcomes. This study reports the analysis of tribal maternal admissions in the community-based hospital of SEWA Rural (Kasturba Maternity Hospital) in Jhagadia block, Gujarat. The objective of the study is to compare the pregnancy outcomes among SCD, sickle cell trait and non-SCD admissions. This study also estimated the risk of adverse pregnancy outcomes for SCD admissions. METHODS: The data pertains to four and half years from March 2011 to September 2015. The total tribal maternal admissions were 14640, out of which 10519 admissions were deliveries. The admissions were classified as sickle cell disease, sickle cell trait and non-sickle cell disease. The selected pregnancy outcomes and maternal complications were abortion, stillbirth, Caesarean section, haemoglobin levels, blood transfusion, preterm pregnancy, newborn birth weight and other diagnosed morbidities (IUGR, PIH, eclampsia, preterm labour pain). The odds ratios for each risk factor were estimated for sickle cell patients. The odds ratios were adjusted for the respective years. RESULTS: Overall, 1.2% (131 out of 10519) of tribal delivery admissions was sickle cell admissions. Another 15.6% (1645 out of 10519) of tribal delivery admissions have sickle cell trait. The percentage of stillbirth was 9.9% among sickle cell delivery admission compared to 4.2% among non-sickle cell deliveries admissions. Among sickle cell deliveries, 70.2% were low birth weight compared to 43.8% of non-sickle cell patient. Similarly, almost half of the sickle cell deliveries needed the blood transfusion. The 45.0% of sickle cell delivery admissions were pre-term births, compared to 17.3% in non-SCD deliveries. The odds ratio of severe anaemia, stillbirth, blood transfusion, Caesarean section, and low birth weight was significantly higher for sickle cell admissions compared to non-sickle cell admissions. CONCLUSIONS: The study exhibited that there is a high risk of adverse pregnancy outcomes for women with SCD. It may also be associated with the poor maternal and neonatal health in these tribal regions. Thus, the study advocates the need for better management of SCD in tribal Gujarat.

Transitioning toward Sustainable Development Goals: The Role of Household Environment in Influencing Child Health in Sub-Saharan Africa and South Asia Using Recent Demographic Health Surveys.

The Millennium Development Goals are now replaced by 17 sustainable development goals. The emphasis of old goals was on improving water, sanitation, and child mortality conditions in developing countries. The study explored the major question about the association between different household environment conditions with child survival and health in Sub-Saharan African and South Asian countries in the current scenario. This paper estimated the risk of death, morbidity, and undernutrition among children living in households with the improved sources of water, sanitation, and non-solid cooking fuel. Two sources of information are explored in this study. First, data from World Health Statistics (WHS)-2014 for all of the Sub-Saharan African and South Asian countries were used. Second, available standard Demographic and Health Survey (DHS) performed in the countries of Sub-Saharan Africa and South Asia after 2010 was included in the study. It resulted in the inclusion of 15 countries which were Bangladesh (2011), Congo Republic (2013-2014), Cote d'Ivoire (2011-2012), Ethiopia (2011), Gambia (2013), Mali (2012-2013), Mozambique (2011), Namibia (2013), Nepal (2011), Niger (2012), Nigeria (2013), Pakistan (2012-2013), Sierra Leone (2013), Uganda (2011), and Zambia (2013). The scatter plot diagram was plotted, and the curve was fitted using the WHS-2014. Cox regression and logistic regression were used to estimate adjusted risks (odds ratio) of child mortality and health outcomes using DHSs. The use of non-solid cooking fuel was very high in most of the Sub-Saharan African and South Asian countries. There was a positive correlation between improving access to safe drinking water and sanitation. The exponential curve fitted well with child mortality and household environmental indicators. The use of improved source of water and sanitation significantly related with the lower odds ratio of death, morbidity, and undernutrition among children aged 12-59 months. The risks were not significant for children aged less than 12 months. The study provides evidence that these environmental conditions hold importance for improving child health, especially in Sub-Saharan African countries.
