Estimation of changes in maternal mortality in a rural district of northern Tanzania during the last 50 years

Tick borne relapsing fever - a systematic review and analysis of the literature

Tick borne relapsing fever (TBRF) is a zoonosis caused by various Borrelia species transmitted to humans by both soft-bodied and (more recently recognized) hard-bodied ticks. In recent years, molecular diagnostic techniques have allowed to extend our knowledge on the global epidemiological picture of this neglected disease. Nevertheless, due to the patchy occurrence of the disease and the lack of large clinical studies, the knowledge on several clinical aspects of the disease remains limited. In order to shed light on some of these aspects, we have systematically reviewed the literature on TBRF and summarized the existing data on epidemiology and clinical aspects of the disease. Publications were identified by using a predefined search strategy on electronic databases and a subsequent review of the reference lists of the obtained publications. All publications reporting patients with a confirmed diagnosis of TBRF published in English, French, Italian, German, and Hungarian were included. Maps showing the epidemiogeographic mosaic of the different TBRF Borrelia species were compiled and data on clinical aspects of TBRF were analysed. The epidemiogeographic mosaic of TBRF is complex and still continues to evolve. Ticks harbouring TBRF Borrelia have been reported worldwide, with the exception of Antarctica and Australia. Although only molecular diagnostic methods allow for species identification, microscopy remains the diagnostic gold standard in most clinical settings. The most suggestive symptom in TBRF is the eponymous relapsing fever (present in 100% of the cases). Thrombocytopenia is the most suggestive laboratory finding in TBRF. Neurological complications are frequent in TBRF. Treatment is with beta-lactams, tetracyclines or macrolids. The risk of Jarisch-Herxheimer reaction (JHR) appears to be lower in TBRF (19.3%) compared to louse-borne relapsing fever (LBRF) (55.8%). The overall case fatality rate of TBRF (6.5%) and LBRF (4-10.2%) appears to not differ. Unlike LBRF, where perinatal fatalities are primarily attributable to abortion, TBRF-related perinatal fatalities appear to primarily affect newborns.

Knowledge and barriers on correct use of modified guidelines for active management of third stage of labour: a cross sectional survey of nurse-midwives at three referral hospitals in Dar es Salaam, Tanzania

Background

Despite the fact that it is possibly preventable, postpartum haemorrhage (PPH) is the global most deadly form of obstetric bleeding, mainly sub-Saharan Africa with at least one-fourth of maternal deaths in East African regions. Active management of third stage of labour (AMTSL) is recommended to prevent PPH. However, AMTSL guidelines have been revised since 2006.

Objectives

To examine the current status of nurse-midwives' knowledge on modified AMTSL guidelines and highlight barriers to AMTSL correct use.

Method

Descriptive cross sectional survey was conducted to 160 nurse-midwives at three referral hospitals in Dar es Salaam, Tanzania. One-way, interactive modes ANOVA and Chi square (χ2) test were run in SPSS 21 version to compare the association of independent and dependent variables.

Results

Virtually all nurse-midwives knew the first recommended uterotonic (99.4%) and delayed cord clamping (98.8%) protocols as modified. Knowledge was significantly contributed by multiple factors; p=0.001. Reported correct AMTSL use was 46.8% which was significantly affected by AMTSL training (χ2 = 6.732, p = 0.009) and prioritizing atteding an asphyxiated baby (χ2 = 5.647, p = 0.017).

Conclusion

Regardless of high nurse-midwives' AMTSL knowledge; it is imperative that responsible authorities plan appropriate strategies to solve reported barriers affecting correct AMTSL use.

Is it home delivery or health facility? Community perceptions on place of childbirth in rural Northwest Tanzania using a qualitative approach

BACKGROUND

In low and middle-income countries, pregnancy and delivery complications may deprive women and their newborns of life or the realization of their full potential. Provision of quality obstetric emergency and childbirth care can reduce maternal and newborn deaths. Underutilization of maternal and childbirth services remains a public health concern in Tanzania. The aim of this study was to explore elements of the local social, cultural, economic, and health systems that influenced the use of health facilities for delivery in a rural setting in Northwest Tanzania.

METHODS

A qualitative approach was used to explore community perceptions of issues related to low utilization of health facilities for childbirth. Between September and December 2017, 11 focus group discussions were conducted with women (n = 33), men (n = 5) and community health workers (CHWs; n = 28); key informant interviews were conducted with traditional birth attendants (TBAs; n = 2). Coding, identification, indexing, charting, and mapping of these interviews was done using NVIVO 12 after manual familiarization of the data. Data saturation was used to determine when no further interviews or discussions were required.

RESULTS

Four themes emerge; self-perceived obstetric risk, socio-cultural issues, economic concerns and health facility related factors. Health facility delivery was perceived to be crucial for complicated labor. However, the idea that childbirth was a "normal" process and lack of social and cultural acceptability of facility services, made home delivery appealing to many women and their families. In addition, out of pocket payments for suboptimal quality of health care was reported to hinder facility delivery.

CONCLUSION

Home delivery persists in rural settings due to economic and social issues, and the cultural meanings attached to childbirth. Accessibility to and affordability of respectful and culturally acceptable childbirth services remain challenging in this setting. Addressing barriers on both the demand and supply side could result in improved maternal and child outcomes during labor and delivery.

The evolving contribution of non-communicable diseases to maternal mortality in Jamaica, 1998-2015: a population-based study

OBJECTIVE

To describe trends in indirect cause-specific pregnancy-related mortality from 1998 to 2015.

DESIGN

Secondary analysis of annual, national cross-sectional database of maternal and late maternal deaths, identified through active surveillance of deaths among women aged 10-50 years.

SETTING

Jamaica, a middle-income Caribbean country.

POPULATION

Maternal and late maternal deaths.

METHODS

Descriptive trend analyses of demographic and cause-specific maternal and pregnancy-related mortality ratios undertaken comparing the periods 1998-2003, 2004-2009 and 2010-2015. Multivariate logistic regression was used to confirm changes in risk of indirect death.

MAIN OUTCOME MEASURES

Maternal, pregnancy-related, direct, indirect and cause-specific mortality ratios (deaths/100 000 live births).

RESULTS

Maternal deaths from indirect conditions increased between the first two periods (P = 0.004) and stabilised in the third (P = 0.085). Associated with upward movement in cardiovascular deaths (P_[trend] = 0.003), women under 25 years were at elevated risk (odds ratio 1.44, 95% CI 1.00-2.08; P = 0.052). Haematological/immunological conditions (69% sickle cell disease) ranked second but did not vary with time. Health service utilisation was similar across age, parity, health region and major cause categories (non-communicable diseases, non-obstetric infections, direct), however women with indirect conditions spent more time in hospital (median 5 days versus 3 days) and more often died after the puerperium.

CONCLUSIONS

Medical conditions, especially cardiovascular disease, are increasingly associated with maternal and late maternal mortality. Middle-income countries need to simultaneously improve management of indirect conditions, while redoubling efforts to reduce direct deaths. Postpuerperal medical services should be integrated into routine infant health services to improve continuity of care during this high-risk period.

TWEETABLE ABSTRACT

Maternal survival (SDG 3.1) in LMICs requires better care for women with both non-communicable diseases and obstetric conditions.

Bacterial arthropod-borne diseases in West Africa

Arthropods such as ticks, lice, fleas and mites are excellent vectors for many pathogenic agents including bacteria, protozoa and viruses to animals. Moreover, many of these pathogens can also be accidentally transmitted to humans throughout the world. Bacterial vector-borne diseases seem to be numerous and very important in human pathology, however, they are often ignored and are not well known. Yet they are in a phase of geographic expansion and play an important role in the etiology of febrile episodes in regions of Africa. Since the introduction of molecular techniques, the presence of these pathogens has been confirmed in various samples from arthropods and animals, and more rarely from human samples in West Africa. In this review, the aim is to summarize the latest information about vector-borne bacteria, focusing on West Africa from 2000 until today in order to better understand the epidemiological risks associated with these arthropods. This will allow health and veterinary authorities to develop a strategy for surveillance of arthropods and bacterial disease in order to protect people and animals.

The Health Systems Barriers and Facilitators for RHD Prevalence: An Epidemiological Meta-Analysis From Uganda and Tanzania

BACKGROUND

Rheumatic heart disease (RHD) is an important and preventable cause of cardiovascular disease.

OBJECTIVES

As part of a recent RHD initiative in Uganda and Tanzania, we systematically reviewed group A streptococcal disease (GAS), acute rheumatic fever (ARF), and RHD in these countries.

METHODS

Using a systematic review and meta-analysis/meta-synthesis, we searched PubMed, Embase, and grey literature for quantitative and qualitative studies conducted in Uganda and Tanzania that included individuals affected by GAS, ARF, and RHD. We pre-specified 3 sets of outcomes: 1) disease epidemiology; 2) barriers and facilitators to health care; and 3) stakeholder identification and engagement. Study descriptors, outcomes, and interest, and quality assessments were recorded. For the first objective, we conducted random-effects meta-analyses. For the second objective, we produced a narrative synthesis of themes. No studies contained data on the third objective.

RESULTS

Of 293 records identified, 12 met our inclusion criteria (9 for objective 1 and 3 for objective 2). Most quantitative studies were at moderate or high risk of bias, and only 1 of 2 qualitative studies was high quality. We estimated the prevalence of RHD to be 17.9 (95% confidence interval [CI]: 4.0 to 41.2) per 1,000 individuals. The most frequent nonfatal sequelae were heart failure, pulmonary hypertension, and atrial fibrillation. Case-fatality rates in medical and surgical wards were 17% (95% CI: 13% to 21%) and 27% (95% CI: 18% to 36%), respectively. Barriers and facilitators to GAS and RHD care were identified in the domains of individual knowledge, family support, provider communication and knowledge, and system design.

CONCLUSIONS

RHD remains endemic in Tanzania and Uganda, and symptomatic RHD is associated with high rates of morbidity and mortality. We have identified critical data gaps in the areas of GAS and ARF epidemiology as well as health care utilization patterns and their determinants.
