Utilization of third-trimester fetal transcerebellar diameter measurement for gestational age estimation: a comparative study using Bland-Altman analysis

BACKGROUND

Several studies show that gestational age estimation during the third trimester of pregnancy using fetal transcerebellar diameter is superior to that measured using fetal biometry (biparietal diameter, head circumference, abdominal circumference, and femur diaphysis length). However, the conclusion of the studies stemmed from findings of correlation and regression statistical tests, which are not the recommended statistical analysis methods for comparing the values of 1 variable as measured by 2 different methods.

OBJECTIVE

This study aimed to compare the accuracy of gestational age estimation using transcerebellar diameter to that using fetal biometry during the third trimester of pregnancy using Bland-Altman statistical analysis.

STUDY DESIGN

This was a cross-sectional study on pregnant women who presented for routine antenatal care follow-up in the third trimester of pregnancy (28-41 weeks of gestation) at St. Paul's Hospital Millennium Medical College (Ethiopia) between November 1, 2020, and February 28, 2021. Data were collected prospectively using a structured questionnaire on the Open Data Kit. The primary outcome of our study was the mean bias of gestational age estimation (error in estimating gestational age) using transcerebellar diameter and composite fetal biometry (composite gestational age). Data were analyzed using Stata (version 15; StataCorp, College Station, TX). Simple descriptive analysis, Bland-Altman analysis, and the Kendall τa discordance measurement were performed as appropriate. The mean bias (error) and limits of agreement were used to present the significance of the finding.

RESULTS

A total of 104 pregnant women in the third trimester were included in the study. The mean error (bias) when transcerebellar diameter was used to estimate the gestational age was 0.65 weeks vs a bias of 1.1 weeks using composite biometry, compared with the gold standard method from crown-lump length (in both cases). The calculated estimated limit of agreement was narrower in the case of transcerebellar diameter than in the case of composite fetal biometry (-3.56 to 2.25 vs -4.73 to 2.53). The Kendall τa discordance measurement revealed that gestational age estimations using composite biometry and crown-lump length were 51% to 70%, respectively, more likely to agree than disagree and that gestational age estimations using transcerebellar diameter and crown-lump length were 62% to 77%, respectively, more likely to agree than to disagree (P≤.001).

CONCLUSION

Gestational age estimation using transcerebellar diameter is more accurate than gestational age estimation using composite gestational age (biparietal diameter, head circumference, femur diaphysis length, and abdominal circumference). Transcerebellar diameter should be used to date third-trimester pregnancies with unknown gestational age (unknown last normal menstrual period with no early ultrasound milestone).

Community exposure to armed conflict and subsequent onset of alcohol use disorder

AIMS

To measure the independent consequences of community-level armed conflict beatings on alcohol use disorders (AUD) among males in Nepal during and after the 2000-2006 conflict.

DESIGN

A population-representative panel study from Nepal, with precise measures of community-level violent events and subsequent individual-level AUD in males. Females were not included because of low AUD prevalence.

SETTING

Chitwan, Nepal.

PARTICIPANTS

Four thousand eight hundred seventy-six males from 151 neighborhoods, systematically selected and representative of Western Chitwan. All residents aged 15-59 were eligible (response rate 93%).

MEASUREMENTS

Measures of beatings in the community during the conflict (2000-2006), including the date and distance away, were gathered through neighborhood reports, geo-location and official resources, then linked to respondents' life histories of AUD (collected in 2016-2018) using the Nepal-specific Composite International Diagnostic Interview with life history calendar. Beatings nearby predict the subsequent onset of AUD during and after the armed conflict. Data were analyzed in 2021-2022.

FINDINGS

Cohort-specific, discrete-time models revealed that within the youngest cohort (born 1992-2001), those living in neighborhoods where armed conflict beatings occurred were more likely to develop AUD compared with those in other neighborhoods (odds ratio = 1.66; 95% confidence interval = 1.02-2.71). In this cohort, a multilevel matching analysis designed to simulate a randomized trial showed the post-conflict incidence of AUD for those living in neighborhoods with any armed conflict beatings was 9.5% compared with 5.3% in the matched sample with no beatings.

CONCLUSIONS

Among male children living in Chitwan, Nepal during the 2000-2006 armed conflict, living in a neighborhood where armed conflict beatings occurred is associated with increased odds of developing subsequent alcohol use disorder. This association was independent of personal exposure to beatings and other mental disorders.

Successful Management, in a Low-Resource Setting, of Disseminated Tuberculosis in a 3-Year Old Boy: A Case Report

Disseminated or military tuberculosis (TB) is defined as the presence of at least two non-contiguous sites of Mycobacterium tuberculosis, occurring as a result of progressive primary infection, reactivation and spread of a latent focus or due to iatrogenic origin. Disseminated TB represents a life-threatening condition, especially in at-risk children and when diagnosis and treatment are delayed. We report on a case of a 3-year old boy who presented with long-lasting unrecognised disseminated TB that was successfully managed in a low-resource setting.

Simultaneous bilateral femoral fracture in children

Introduction

Bilateral femoral fractures in children (BFFC) are an uncommon condition. Only a few cases were reported in the literature. The frequency and outcome in low-setting facilities are unknown. This study aims to describe our experience in managing BFFC.

Patients and Methods

A 10-year ongoing study spanning from 2010 to 2020 was held in a level-1 paediatric facility. We included all cases of BFFC on a bone-free disease with at least 10 months of follow-up time. Data were collected and analysed with statistical software.

Results

A total of eight patients with ten BFFC were collected. It involved mainly boys (n = 7/8) with median age of 8 years. Mechanism of injury were a road traffic accident (n = 4), a fall from height (n = 3), and been crushed by a falling wall (n = 1). Associated injuries were frequent (n = 6/8). Patients were managed nonoperatively with spica cast (n = 5) and by elastic intramedullary nails (n = 3). After 6.11 years of mean follow-up time, all fractures healed. The outcome was excellent and good in 7 cases. One patient sustained knees stiffness.

Conclusion

Non-operative management of BFFC showed satisfactory outcomes. Early surgical care must be developed in our low-income settings to reduce in-hospital stay and encourage early weight-bearing.

Depression and Burnout among Health Extension Workers in Ethiopia: A Cross-Sectional Study

Background

Depression and burnout are common among healthcare workers (HCWs) and negatively affect their well-being and the quality of the service they provide. However, the burden of depression and burnout among health extension workers (HEWs) in Ethiopia and their relationship has not been documented well.The objective of this study was to estimate the prevalence of depression and burnout among HEWs in Ethiopia and to investigate the relationship between these conditions.

Materials and Methods

We used a cross-sectional study design and collected data from 584 rural and 581 urban HEWs in Ethiopia, as part of the 2019 national health extension program assessment. The Patient Health Questionnaire (PHQ-9) and Burnout Self-Test were used to screen HEWs for depression and burnout, respectively. We used descriptive statistics to estimate the magnitude of depression and burnout, and logistic regression to examine their relationship.

Result

Based on PHQ-9 cutoff scores of 10, the prevalence of major depression was 16.5% among rural and 8.9% among urban HEWs, whereas burnout risk was 39.8% among rural and 12.6% among urban HEWs. The odds of having depression among HEWs with burnout risk was relatively higher compared to those without burnout risk [For rural HEWs, the adjusted odds ratio (AOR) is 11.88 at a 95% confidence interval (CI; 5.27, 26.80), and for urban HEWs, the AOR is 11.49 at a 95% CI (5.35, 24.63)].

Conclusion

The prevalence of depression and burnout is high among HEWs in Ethiopia, with a significant rural-urban difference, and burnout is a significant predictor of depression. Mental health interventions that enable prevention, early detection, and management are needed especially for rural HEWs who are in charge of preventive health service delivery for the disadvantaged rural communities.

Chronic aflatoxin exposure during pregnancy is associated with lower fetal growth trajectories: a prospective cohort from the Butajira Nutrition, Mental Health, and Pregnancy (BUNMAP) Study in rural Ethiopia

BACKGROUND

Aflatoxins are toxic secondary metabolites produced by Aspergillus fungi, which are ubiquitously present in the food supplies of low- and middle-income countries. Studies of maternal aflatoxin exposure and fetal outcomes are mainly focused on size at birth and the effect on intrauterine fetal growth has not been assessed.

OBJECTIVES

In the present study, we examined the association between chronic aflatoxin exposure during pregnancy and fetal growth trajectories in a rural setting in Ethiopia.

METHODS

In a prospective cohort study, we enrolled 492 pregnant females, with a singleton pregnancy and before 28 wk of gestation. Serum aflatoxin B1-lysine concentration was measured using LC-tandem MS. Three rounds of ultrasound measurements were conducted to estimate fetal weight at mean ± SD gestational age weeks of 19.1 ± 3.71, 28.5 ± 3.51, and 34.5 ± 2.44. Estimated fetal weight was expressed in centiles using the International Fetal and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st) reference. We fitted a multivariable linear mixed-effects model to estimate the rate of fetal growth between aflatoxin-exposed (i.e., aflatoxin B1-lysine concentration above or equal to the limit of detection) and unexposed mothers in the study.

RESULTS

Mothers had a mean ± SD age of 26.0 ± 4.58 y. The median (25th, 75th percentile) serum aflatoxin B1-lysine concentration was 12.6 (0.93, 96.9) pg/mg albumin, and aflatoxin exposure was observed in 86.6% of maternal blood samples. Eighty-five percent of the females enrolled provided at least 2 ultrasound measurements for analysis. On average, the aflatoxin-exposed group had a significantly lower change over time in fetal weight-for-gestational-age centile than the unexposed group (ß = -0.92; 95% CI: -1.77, -0.06 centiles/week; P = 0.037).

CONCLUSIONS

Chronic maternal aflatoxin exposure is associated with lower fetal growth over time. Our findings emphasize the importance of nutrition-sensitive strategies to mitigate dietary aflatoxin exposure and adopting food safety measures in low-income settings, in particular during the fetal period of development.

A Single-Arm Pilot Study of Multicomponent Psychoeducational Intervention for Postpartum Depression and Anxiety in a Rural Community

BACKGROUND

The prevalence of postpartum depression (PPD) and anxiety (PPA) is rising in India and efforts at generating local evidence for psychological intervention are scanty. We conducted a single-arm pilot study in an Indian rural community to test the impact of multicomponent psychoeducational intervention (MCPI) on women with PPD and PPA.

METHODS

Forty-three women with PPD/PPA/both received MCPI, which comprised three phases with in-person sessions held once weekly for a minimum of six and a maximum of ten weeks. Primary outcome variables were scores on depression and anxiety, assessed using the Edinburg postnatal depression scale and the state and trait anxiety inventory, along with evaluating the compliance rate to the intervention. The Mini-international neuropsychiatric interview (MINI) neuropsychiatric interview was used to confirm the diagnosis of depression and anxiety. Secondary outcome variables assessed were social support, functionality, parental stress, interpersonal violence, and marital satisfaction. We used Cohen's d effect size method for assessing the mean differences.

RESULTS

MCPI resulted in the improvement of 72% women (95% CI = 56.3%-84.7%). The overall compliance rate to the intervention was 85.63%, which was higher for responders than nonresponders (92.9% vs. 69.8%; P < 0.001). MCPI resulted in statistically significant improvement in the mean score of depression (P = 0.001, d = 0.95) and anxiety (P = 0.001, d = 1.30). On secondary outcome variables, significant improvement was obtained in the overall present social support (P = 0.001; d = 4.65), present social support from partner (P = 0.027; d = 0.45) and parents (P = 0.001; d = 0.74), future social support from parents (P = 0.001; d = 0.81), the performance of household responsibility (P = 0.001; d = 0.97), lifestyle in the last two weeks (P = 0.001; d = 3.57), parental stress (P = 0.001; d = 1.04), and marital satisfaction (P = 0.014; d = 0.52).

CONCLUSION

This pilot study shows that MCPI has a promising role in relieving depression and anxiety. It also improved the perception of social support from partner and parents, functionality, marital satisfaction, and reduced parental stress.

Too busy to care? Analysing the impact of system-related factors on maternal mortality in Zanzibar's Referral Hospital

This study analyses the contribution of system-related factors to maternal mortality in the low-resource setting of Mnazi Mmoja Hospital in Zanzibar, Tanzania. It is a retrospective cohort study including all maternal deaths (MD, n = 139) and maternal near-misses (MNM, n = 122) in Mnazi Mmoja Hospital with sufficient documentation during 2015 to 2018 (MD) and 2017 to 2018 (MNM). The number of admissions and surgical interventions per health care provider on the day of admission and the number of times vital signs were monitored per day were compared between MNM and MD cases using logistic regression. The mean number of times vital signs were monitored per day was associated with reduced odds of mortality (aOR 0.75, 95% CI 0.64-0.89), after adjustment for confounding factors such as severity of illness. The numbers of admissions or surgical procedures per health care provider were not associated with mortality. Concluding, the degree of monitoring of patients with life-threatening complications of pregnancy or childbirth is associated with the risk of mortality independent of the degree of severity. Preventing maternal mortality requires going beyond availability of essential interventions to tackle system-related factors that have a direct impact on the capacity to provide comprehensive care.Impact StatementWhat is already known on this subject? Root cause analyses of maternal deaths have identified many system-related factors, such as availability of health care providers, adequate training, and motivation to sustain high intensity monitoring (Madzimbamuto et al. 2014; Mahmood et al. 2018).What do the results of this study add? This is the first study to attempt to quantify the contribution of these system-related factors by comparing cases of maternal death with cases of maternal near-miss. We show that the degree of monitoring of patients with life-threatening complications is associated with the odds of mortality independent of the degree of severity. Even though this relation should not be regarded as causative, monitoring of vital signs can be seen as reflective of many system-related factors which hamper or facilitate comprehensive care.What are the implications of these findings for clinical practice and/or further research? This study helps increase general understanding of the factors leading to progression from severe disease to death in a high-volume low-income setting.

COVID-19 and Kidney Disease: Progress in Health Inequity From Low-Income Settings

The acute coronavirus disease-2019 (COVID-19) pandemic has had a significant impact on the incidence and prevalence of acute kidney injury and chronic kidney disease globally and in low-income settings. Chronic kidney disease increases the risk of developing COVID-19 and COVID-19 causes acute kidney injury directly or indirectly and is associated with high mortality in severe cases. Outcomes of COVID-19-associated kidney disease were not equitable globally owing to a lack of health infrastructure, challenges in diagnostic testing, and management of COVID-19 in low-income settings. COVID-19 also significantly impacted kidney transplant rates and mortality among kidney transplant recipients. Vaccine availability and uptake remains a significant challenge in low- and lower-middle-income countries compared with high-income countries. In this review, we explore the inequities in low- and lower-middle-income countries and highlight the progress made in the prevention, diagnosis, and management of patients with COVID-19 and kidney disease. We recommend further studies into the challenges, lessons learned, and progress made in the diagnosis, management, and treatment of patients with COVID-19-related kidney diseases and suggest ways to improve the care and management of patients with COVID-19 and kidney disease.

Oocyst Shedding Dynamics in Children with Cryptosporidiosis: a Prospective Clinical Case Series in Ethiopia

Knowledge on the duration of Cryptosporidium oocyst shedding, and how shedding may be affected by subtypes and clinical parameters, is limited. Reduced transmission may be a secondary benefit of cryptosporidiosis treatment in high-prevalence areas. We conducted a prospective clinical case series in children of <5 years presenting with diarrhea to a health center and a hospital in Ethiopia over an 18-month period. Stool samples were collected repeatedly from children diagnosed with cryptosporidiosis for up to 60 days. Samples were examined, and Cryptosporidium shedding was quantified, using auramine phenol, immunofluorescent antibody staining, and quantitative PCR (qPCR). In addition, species determination and subtyping were used to attempt to distinguish between new infections and ongoing shedding. Duration and quantity of shedding over time were estimated by time-to-event and quantitative models (sex- and age-adjusted). We also explored how diarrheal severity, acute malnutrition, and Cryptosporidium subtypes correlated with temporal shedding patterns. From 53 confirmed cryptosporidiosis cases, a median of 4 (range 1 to 5) follow-up stool samples were collected and tested for Cryptosporidium. The median duration of oocyst shedding was 31 days (95% confidence interval [CI], 26 to 36 days) after onset of diarrhea, with similar estimates from the quantitative models (31 days, 95% CI 27 to 37 days). Genotype shift occurred in 5 cases (9%). A 10-fold drop in quantity occurred per week for the first 4 weeks. Prolonged oocyst shedding is common in a pediatric clinical population with cryptosporidiosis. We suggest that future intervention trials should evaluate both clinical efficacy and total parasite shedding duration as trial endpoints. IMPORTANCE Cryptosporidiosis is an important cause of diarrhea, malnutrition, and deaths in young children in low-income countries. The infection spreads from person to person. After infection, prolonged release of the Cryptosporidium parasite in stool (shedding) may contribute to further spread of the disease. If diagnosis and treatment are made available, diarrhea will be treated and deaths will be reduced. An added benefit may be to reduce transmission to others. However, shedding duration and its characteristics in children is not well known. We therefore investigated the duration of shedding in a group of young children who sought health care for diarrhea in a hospital and health center in Ethiopia. The study followed 53 children with cryptosporidiosis for 2 months. We found that, on average, children released the parasite for 31 days after the diarrhea episode started. Point-of-care treatment of cryptosporidiosis may therefore reduce onward spread of the Cryptosporidium parasite within communities and households.

An intensive model of care for hepatitis C virus screening and treatment with direct-acting antivirals in people who inject drugs in Nairobi, Kenya: a model-based cost-effectiveness analysis

BACKGROUND AND AIMS

Hepatitis C virus (HCV) treatment is essential for eliminating HCV in people who inject drugs (PWID), but has limited coverage in resource-limited settings. We measured the cost-effectiveness of a pilot HCV screening and treatment intervention using directly observed therapy among PWID attending harm reduction services in Nairobi, Kenya.

DESIGN

We utilized an existing model of HIV and HCV transmission among current and former PWID in Nairobi to estimate the cost-effectiveness of screening and treatment for HCV, including prevention benefits versus no screening and treatment. The cure rate of treatment and costs for screening and treatment were estimated from intervention data, while other model parameters were derived from literature. Cost-effectiveness was evaluated over a life-time horizon from the health-care provider's perspective. One-way and probabilistic sensitivity analyses were performed.

SETTING

Nairobi, Kenya.

POPULATION

PWID.

MEASUREMENTS

Treatment costs, incremental cost-effectiveness ratio (cost per disability-adjusted life year averted).

FINDINGS

The cost per disability-adjusted life-year averted for the intervention was $975, with 92.1% of the probabilistic sensitivity analyses simulations falling below the per capita gross domestic product for Kenya ($1509; commonly used as a suitable threshold for determining whether an intervention is cost-effective). However, the intervention was not cost-effective at the opportunity cost-based cost-effectiveness threshold of $647 per disability-adjusted life-year averted. Sensitivity analyses showed that the intervention could provide more value for money by including modelled estimates for HCV disease care costs, assuming lower drug prices ($75 instead of $728 per course) and excluding directly-observed therapy costs.

CONCLUSIONS

The current strategy of screening and treatment for hepatitis C virus (HCV) among people who inject drugs in Nairobi is likely to be highly cost-effective with currently available cheaper drug prices, if directly-observed therapy is not used and HCV disease care costs are accounted for.

The effects of in utero exposure to teratogens on organ size: a prospective paediatric study

In low-income countries, prospective data on combined effects of in utero teratogen exposure are lacking and necessitates new research. The aim of the present study was to explore the effect of in utero teratogen exposure on the size of the kidneys and pancreas 5 years after birth in a low-income paediatric population. Data was collected from 500 mother-child pairs from a low-income setting. Anthropometric measurements included body weight, (BW) body height, mid-upper arm and waist circumference (WC). Clinical measurements included blood pressure (BP), mean arterial pressure and heart rate. Ultrasound measurements included pancreas, and kidney measurements at age 5 years. The main outcome of interest was the effect of maternal smoking and alcohol consumption on ultrasound measurements of organ size at age 5 years. Left and right kidney length measurements were significantly lower in smoking exposed children compared to controls (p = 0.04 and p = 0.03). Pancreas body measurements were significantly lower in smoking exposed children (p = 0.04). Multiple regression analyses were used to examine the associations between the independent variables (IDVs), maternal age, body mass index (BMI), mid-upper arm circumference (MUAC) and BW of the child, on the dependent variables (DVs) kidney lengths and kidney volumes. Also, the association between in utero exposure to alcohol and nicotine and pancreas size. WC was strongest (r = 0.28; p < 0.01) associated with pancreas head [F (4, 454) = 13.44; R2 = 0.11; p < 0.01] and tail (r = 0.30; p < 0.01) measurements at age 5 years, with in utero exposure, sex of the child and BMI as covariates. Kidney length and pancreas body measurements are affected by in utero exposure to nicotine at age 5 years and might contribute to cardiometabolic risk in later life. Also, findings from this study report on ultrasound reference values for kidney and pancreas measurements of children at age 5 years from a low-income setting.

Tetanus in a rural low-income intensive care unit setting

Tetanus is a potentially severe but preventable infection. In resource-rich settings, vaccination programmes have reduced tetanus to a rare disease, though still carrying an overall mortality of some 13%. However, in low-income settings, tetanus remains common, and is a significant cause of mortality-though major World Health Organisation programmes are successfully targeting neonatal and maternal disease. Data concerning the frequency and outcomes of non-neonatal tetanus in low-income settings are very sparse. We aimed to utilize a unique intensive care unit-based dataset to elicit clinical and demographic features and mortality in a large cohort of tetanus patients admitted over an eleven-year period to a single hospital centre in a rural low-income setting in northern Uganda. A total of 268 patients with tetanus were admitted to the Intensive Care Unit at St Mary's Hospital, Lacor between 2005 and 2015; the records of 190 were retrievable and had sufficient information to be assessed. 29 were neonates (median age 7 days, IQR 0), 52 children (1-16yrs; median age 11 years, IQR 4.5) and 109 were adults (median age 42 years, IQR 23). There was no seasonal pattern in the frequency of admissions. Of the 190 patients, 69 had endotracheal intubation with intermitent positive pressure ventilation, and 57 patients had central line placement. The overall mortality was 51.5-72.4% in neonatal disease, 25% in children and 57.8% in adults. The requirements for neither central line insertion, nor endotracheal intubation, nor intermittent positive pressure ventilation were independently linked to mortality rates. By contrast with neonatal and childhood disease, there was a marked male preponderance in adult tetanus-94 males and 15 females (gender difference P < 0.001)-and although year-on-year breakdown suggested no obvious upward or downward trend over the span of our study in total numbers of tetanus admissions, a trend towards an increasing incidence of adult tetanus was apparent.These findings confirm that adult tetanus remains a major problem in rural low-income settings, particularly in males, and suggests that more resources should be devoted to vaccination programmes targeting men.

Hypothermic treatment for neonatal asphyxia in low-resource settings using phase-changing material-An easy to use and low-cost method

AIM

To evaluate whether phase-changing material can be used for therapeutic hypothermia of asphyxiated newborns in low-resource settings.

METHODS

Prospective interventional study of asphyxiated term infants fulfilling criteria for hypothermia treatment at Vietnam National Children's Hospital from September 2014 to September 2016. Hypothermia was induced within 6 hours after birth and maintained for 72 hours by a phase-changing material mattress with melting point of 32°C. Rectal temperature was continuously measured, and deviations from target temperature range 33.5-34.5°C were recorded.

RESULTS

In total 52 infants (mean gestational age 39.3 ± 1.1 weeks) included and cooled, the median temperature at initiation of cooling was 35.3 (IQR 34.5-35.9)°C. The median time to reach target temperature was 2.5 (IQR 2-3) hours. The mean temperature during the cooling phase was 33.95 ± 0.2°C. Throughout the cooling phase, the target temperature range (33.5-34.5°C) was maintained more than 80% of the time. Rate of rewarming was 0.5 ± 0.14°C/hour.

CONCLUSION

Phase-changing material can be used as an effective cooling method. Though not a servo-controlled system, it is easy to induce hypothermia, maintain target temperature and rewarm infants in a slow and controlled manner without need for frequent changes and minimum risk of skin injury.

Information-seeking in first visit pregnant women in Khayelitsha, South Africa

Background

The quality of the decisions made by women during pregnancy, especially their first visit, depends on their health needs, their health-seeking behaviour and the type of information available to them.

Aim

This study describes the health education needs, information barriers and health information-seeking behaviour of pregnant women on their first visit to antenatal clinics in a low-income setting in the Western Cape.

Setting

The setting was two antenatal facilities in Khayelitsha Health District facilities in South Africa.

Methods

A quantitative descriptive survey was conducted. A systematic random sample of 261 antenatal first visit attendees between May and July 2016 was selected. Data were collected using a researcher-administered questionnaire and was analysed using descriptive statistics, 95% confidence intervals and non-parametric tests.

Results

The response rate of the study was 92% (n = 240). Pregnant women attending an antenatal clinic for the first time reported high information needs with low health information-seeking behaviours and high information barriers. Doctors, nurses (2.2, ±1.0), family and friends (2.0, ±0.6) were the most frequently used sources of health information, while watching television or listening to the radio (1.5, ±0.9) were the least used sources of health information. Having a medical diagnosis (p < 0.001) and being of an advanced maternal age (p = 0.005) were predictive of higher health-seeking behaviour. The reliance on passively receiving information from health sources may indicate low levels of health literacy and its inverse relationship to health promoting behaviours which should be the subject of further investigation.

"I lost my happiness, I felt half dead and half alive" - a qualitative study of the long-term aftermath of obstetric near-miss in the urban district of Zanzibar, Tanzania

BACKGROUND

This study aims to explore the stories of three women from Zanzibar, Tanzania, who survived life-threatening obstetric complications. Their narratives will increase understanding of the individual and community-level burden masked behind the statistics of maternal morbidity and mortality in Tanzania. In line with a recent systematic review of women-centred, qualitative maternal morbidity research, this study will contribute to guidance of local and global maternal health agendas.

METHODS

This two-phased qualitative study was conducted in July-August 2017 and July-August 2018, and involved three key informants, who were recruited from a maternal near-miss cohort in May 2017 in Mnazi Mmoja Hospital, Zanzibar. The used methods were participant observation, interviews (informal, unstructured and semi-structured), participatory methods and focus group discussions. Data analysis relied primarily on grounded theory, leading to a theoretical model, which was validated repeatedly by the informants and within the study team. The findings were then positioned in the existing literature. Approval was granted by Zanzibar's Medical Ethical Research Committee (reference number: ZAMREC/0002/JUN/17).

RESULTS

The impact of severe maternal morbidity was found to be multi-dimensional and to extend beyond hospital discharge and thus institutionalized care. Four key areas impacted by maternal morbidities emerged, namely (1) social, (2) sexual and reproductive, (3) psychological, and (4) economic well-being.

CONCLUSIONS

This study showed how three women's lives and livelihoods were profoundly impacted by the severe obstetric complications they had survived, even up to 16 months later. These impacts took a toll on their physical, social, economic, sexual and psychological well-being, and affected family and community members alike. These findings advocate for a holistic, dignified, patient value-based approach to the necessary improvement of maternal health care in low-income settings. Furthermore, it emphasizes the need for strategies to be directed not only towards quality of care during pregnancy and delivery, but also towards support after obstetric complications.

Mortality Over Long-term Follow-up for People With HIV Receiving Longitudinal Care and Antiretroviral Therapy in Rural Haiti

BACKGROUND

Deaths from HIV have fallen dramatically with the increasing availability of fully suppressive antiretroviral therapy (ART), and yet HIV remains the ninth leading cause of death in low-income countries. As more people with HIV enter care and receive ART, the focus will need to shift from expanding ART to including long-term program effectiveness and outcomes for people with HIV already engaged in care.

METHODS

We evaluated risk factors for mortality among people with HIV on ART receiving longitudinal care in rural Haiti. We assessed baseline characteristics using a household survey and abstracted clinical characteristics from the electronic record. We used multivariable Cox regression models to identify risk factors for mortality.

RESULTS

There were 464 people included in this study with a median follow-up (interquartile range [IQR]) of 69 (44-77) months, during which time 37 (8%) were lost to follow-up and 118 (25%) died (median time to death [IQR], 29 [12-53] months). After adjustment, poverty (adjusted hazard ratio [AHR], 1.12 per 10-percentage point increased probability; 95% CI, 1.01-1.24) and single marital status (AHR, 1.59; 95% CI, 1.08-2.36) were associated with increased mortality. Age (AHR, 0.78 per 10-year increase; 95% CI, 0.64-0.94), role function quality of life (AHR, 0.75 per quintile increase; 95% CI, 0.62-0.90), and CD4 count (AHR, 0.66 per 100 cells/μL; 95% CI, 0.58-0.75) were associated with decreased mortality.

CONCLUSIONS

Poverty, marital status, and quality of life were associated with mortality. Social protection should be evaluated as a strategy to reduce mortality for people with HIV in concert with increasing access to ART.

DESIGN

A mixed-method study implemented in three phases between October 2015 and February 2016.

SETTINGS

The study was implemented in two subdistricts of Bangladesh.

PARTICIPANTS

Caregivers of children aged 2-59 months, health service providers and key stakeholders at national and district level.

INTERVENTIONS

An intervention including training and job aids and user-friendly instructions was introduced in one subdistrict while standard amoxicillin DT packaging and instructions with no training served as the control in the comparison subdistrict.

PRIMARY OUTCOME

Adherence behaviour of caregivers of children aged 2-59 months for the treatment of childhood pneumonia with amoxicillin DT.

METHODS

We conducted a survey with 56 caregivers in the intervention subdistrict and 38 caregivers in the comparison subdistrict. We also conducted 44 in-depth interviews to evaluate the job aids and user-friendly instructions with healthcare providers and caregivers to assess the feasibility, usability and acceptability of the tools in intervention subdistrict.

RESULTS

For 5-day treatment course, 32.1% (95% CI 23.1% to 41.1%) of caregivers in the intervention subdistrict and 2.6% (95% CI 0.3% to 7.8%) in the comparison subdistrict maintained full adherence to the amoxicillin DT treatment for pneumonia. More children under 12 months were given age-appropriate treatment than older children. Key stakeholders and healthcare providers considered the use and integration of the tools into the health system to be feasible and acceptable.

CONCLUSIONS

The provision of tools for the treatment of childhood pneumonia with amoxicillin DT had a positive influence on adherence behaviours. These tools can help close information gaps and overcome the barriers posed by medical illiteracy and remembering instructions from providers.

Reflections on the Use of Audio Diaries to Access Young People's Lived Experiences of HIV in Zimbabwe

This methodological article reflects on the contribution audio diaries can make to accessing important, and commonly silenced, dimensions of the lived experience of growing up with HIV and their acceptability to children. Audio diaries were used by 12 young people, aged 11 to 13 years, as part of a longitudinal qualitative study embedded within the Anti-Retroviral Research for Watoto (ARROW) clinical trial. The method provided an alternative means for young people to express detailed reflections on their day-to-day encounters, as well as ordinarily silenced topics, including hidden and suppressed emotions regarding the circumstance surrounding their perinatal infection. Although the audio diary has great potential as method, its efficacy rests on young people's understanding of how to use it. There are ethical challenges around maintaining confidentiality while participants are in possession of the diaries and provision of appropriate support. The technology used in the study was in many ways cumbersome compared with opportunities increasingly available.

Cost-Effectiveness of a Comprehensive Approach for Hypertension Control in Low-Income Settings in Argentina: Trial-Based Analysis of the Hypertension Control Program in Argentina

BACKGROUND

A recent cluster randomized trial evaluating a multicomponent intervention showed significant reductions in blood pressure in low-income hypertensive subjects in Argentina.

OBJECTIVES

To assess the cost-effectiveness of this intervention.

METHODS

A total of 1432 hypertensive participants were recruited from 18 primary health care centers. The intervention included home visits led by community health workers, physician education, and text messaging. Resource use and quality of life data using the three-level EuroQol five-dimensional questionnaire were prospectively collected. The study perspective was that of the public health care system, and the time horizon was 18 months. Intention-to-treat analysis was used to analyze cost and health outcomes (systolic blood pressure [SBP] change and quality-adjusted life-years [QALYs]). A 1 time gross domestic product per capita per QALY was used as the cost-effectiveness threshold (US $14,062).

RESULTS

Baseline characteristics were similar in the two arms. QALYs significantly increased by 0.06 (95% confidence interval [CI] 0.04-0.09) in the intervention group, and SBP net difference favored the intervention group: 5.3 mm Hg (95% CI 0.27-10.34). Mean total costs per participant were higher in the intervention arm: US $304 in the intervention group and US $154 in the control group (adjusted difference of US $140.18; 95% CI US $75.41-US $204.94). The incremental cost-effectiveness ratio was $3299 per QALY (95% credible interval 1635-6099) and US $26 per mm Hg of SBP (95% credible interval 13-46). Subgroup analysis showed that the intervention was cost-effective in all prespecified subgroups (age, sex, cardiovascular risk, and body mass index).

CONCLUSIONS

The multicomponent intervention was cost-effective for blood pressure control among low-income hypertensive patients.

Surrogate mother - praiseworthy or stigmatized: a qualitative study on perceptions of surrogacy in Assam, India

Background: Surrogacy is a reproductive practice that has been strongly marketed in India as a solution for childless couples. As a result, the number of surrogacy clinics is increasing. Meanwhile, a global discourse on surrogacy, originating from a Western perspective, has characterized surrogacy as being exploitative of women in low-income settings, where poverty drives them to become surrogate mothers.

Objective: This study explored perspectives on surrogacy from men and women in Assam, an Indian state known to be a low-income setting. Surrogacy arrangements in Assam are still uncommon. It can be expected that the dominant global discourses on surrogacy will be unfamiliar to the general population, and the objective was also to position the results within the divergent global discourses of surrogacy.

Methods: In order to explore local views on surrogacy, we conducted individual interviews and focus group discussions with people from various socioeconomic groups in Assam.

Results: Our findings reveal that people in Assam perceive surrogacy as a good option for a childless couple, as it would result in a child who is a ‘blood’ relation – something highly desirable for sociocultural reasons. However, the part played by the surrogate mother complicates local views on surrogacy. Most people consider payment to the surrogate mother contrary to societal norms. A surrogate mother is also often judged in a moral light, either as a ‘bad mother’ for selling her child, or as a ‘noble woman’ who has helped a childless couple and deserves payment for her services.

Conclusions: In order to decrease the stigmatization of women, a regulatory policy is needed that will take into account the complex understandings of surrogacy and perceptions of surrogate mothers in Indian society. In policy, the possible effect of the dominant exploitation discourse needs to be modulated by local understandings of this reproduction method.

The effect of nutritional supplementation on quality of life in people living with HIV: a randomised controlled trial

OBJECTIVE

To determine the effects of lipid-based nutrient supplements (LNS) on the quality of life of people living with HIV (PLHIV) during the first 3 months of antiretroviral treatment (ART) and to investigate the effects of timing of supplementation by comparing with supplementation during the subsequent 3 months.

METHODS

A randomised controlled trial was conducted in three ART clinics within public health facilities in Jimma, Ethiopia. Participants were PLHIV eligible to start ART with body mass index >17 kg/m(2) and given daily supplements of 200 g of LNS containing whey or soya either during the first 3 months or the subsequent months of ART. The outcome was measured in terms of total quality-of-life scores on the adapted version of the WHOQOL-HIV-BREF assessed at baseline, three and six months.

RESULTS

Of the 282 participants, 186 (66.0%) were women. The mean age (SD) was 32.8 (±9.0) years, and the mean (SD) total quality-of-life score was 82.0 (±14.8) at baseline assessment. At 3 months, participants who received LNS showed better quality of life than those who only received ART without LNS (β = 6.2, 95% CI: 2.9: 9.6). At 6 months, there was no difference in total quality-of-life score between the early and delayed supplementation groups (β = 3.0, 95% CI: -0.4: 6.4). However, the early supplementation group showed higher scores on the social and spirituality domains than the delayed group.

CONCLUSIONS

LNS given during the first three months of ART improves the quality of life of PLHIV.

Effectiveness of a two-stage strategy with HPV testing followed by visual inspection with acetic acid for cervical cancer screening in a low-income setting

The World Health Organization recently advocated a two-stage strategy with human papillomavirus (HPV) testing followed by visual inspection of the cervix with acetic acid (VIA) as a suitable option for cervical cancer screening. However, its accuracy has never been directly assessed in the context of primary screening. To evaluate effectiveness of HPV testing on self-obtained specimens (self-HPV) followed by VIA (sequential testing) in a low-income setting, we recruited 540 women aged between 30 and 65 years in two Cameroonian periurban areas. Eligible women were counseled about cervical cancer and how to perform self-sampling. HPV positive and a random sample of HPV-negative women were called back for VIA and biopsy. Disease was defined by interpretation of cervical intraepithelial neoplasia Grade 2 or worse (CIN2+). Performances of VIA, self-HPV and sequential testing were determined after adjustment for verification bias. HPV prevalence was 27.0%. VIA positivity was 12.9% and disease prevalence was 5%. Sensitivity and specificity of VIA for CIN2+ were 36.4% [95% confidence interval (CI): 15.2-64.6%] and 90.4% (95% CI: 85.4-93.7%), respectively. Sensitivity of self-HPV [100.0% (95% CI: 79.6-100.0%)] was 66% higher than that of sequential testing [33.3% (95% CI: 15.2-58.3%)]. Meanwhile, specificity of self-HPV [74.5% (95% CI: 70.6-78.1%)] was 22% lower than that of sequential testing [96.7% (95% CI: 94.8-97.9%)]. A two-stage screening strategy with self-HPV followed by VIA improves specificity of cervical cancer screening, but at the cost of an important loss of sensitivity. Ways to improve VIA performance or other tools are needed to increase positive predictive value of HPV testing.
