RESUMO

Traditionally, neuroscience and psychology have studied the human brain during periods of "online" attention to the environment, while participants actively engage in processing sensory stimuli. However, emerging evidence shows that the waking brain also intermittently enters an "offline" state, during which sensory processing is inhibited and our attention shifts inward. In fact, humans may spend up to half of their waking hours offline [Wamsley, E. J., & Summer, T. Spontaneous entry into an "offline" state during wakefulness: A mechanism of memory consolidation? Journal of Cognitive Neuroscience, 32, 1714-1734, 2020; Killingsworth, M. A., & Gilbert, D. T. A wandering mind is an unhappy mind. Science, 330, 932, 2010]. The function of alternating between online and offline forms of wakefulness remains unknown. We hypothesized that rapidly switching between online and offline states enables the brain to alternate between the competing demands of encoding new information and consolidating already-encoded information. A total of 46 participants (34 female) trained on a memory task just before a 30-min retention interval, during which they completed a simple attention task while undergoing simultaneous high-density EEG and pupillometry recording. We used a data-driven method to parse this retention interval into a sequence of discrete online and offline states, with a 5-sec temporal resolution. We found evidence for three distinct states, one of which was an offline state with features well-suited to support memory consolidation, including increased EEG slow oscillation power, reduced attention to the external environment, and increased pupil diameter (a proxy for increased norepinephrine). Participants who spent more time in this offline state following encoding showed improved memory at delayed test. These observations are consistent with the hypothesis that even brief, seconds-long entry into an offline state may support the early stages of memory consolidation.

RESUMO

While global patterns of human genetic diversity are increasingly well characterized, the diversity of human languages remains less systematically described. Here, we outline the Grambank database. With over 400,000 data points and 2400 languages, Grambank is the largest comparative grammatical database available. The comprehensiveness of Grambank allows us to quantify the relative effects of genealogical inheritance and geographic proximity on the structural diversity of the world's languages, evaluate constraints on linguistic diversity, and identify the world's most unusual languages. An analysis of the consequences of language loss reveals that the reduction in diversity will be strikingly uneven across the major linguistic regions of the world. Without sustained efforts to document and revitalize endangered languages, our linguistic window into human history, cognition, and culture will be seriously fragmented.

RESUMO

OBJECTIVE: The aim of this study is to explore whether cortical activation and its lateralization during motor imagery (MI) in subacute spinal cord injury (SCI) are indicative of existing or upcoming central neuropathic pain (CNP). METHODS: Multichannel electroencephalogram was recorded during MI of both hands in four groups of participants: able-bodied (N = 10), SCI and CNP (N = 11), SCI who developed CNP within 6 months of EEG recording (N = 10), and SCI who remained CNP-free (N = 10). Source activations and its lateralization were derived in four frequency bands in 20 regions spanning sensorimotor cortex and pain matrix. RESULTS: Statistically significant differences in lateralization were found in the theta band in premotor cortex (upcoming vs existing CNP, p = 0.036), in the alpha band at the insula (healthy vs upcoming CNP, p = 0.012), and in the higher beta band at the somatosensory association cortex (no CNP vs upcoming CNP, p = 0.042). People with upcoming CNP had stronger activation compared to those with no CNP in the higher beta band for MI of both hands. CONCLUSIONS: Activation intensity and lateralization during MI in pain-related areas might hold a predictive value for CNP. SIGNIFICANCE: The study increases understanding of the mechanisms underlying transition from asymptomatic to symptomatic early CNP in SCI.

RESUMO

BACKGROUND & AIMS: Patients with liver disease can be stratified for risk of liver-related ill health by degree of hepatic fibrosis. The Enhanced liver fibrosis (ELF) test was developed to quantify hepatic fibrosis non-invasively and is widely used. The objective of this review was to identify and synthesise the evidence on the diagnostic accuracy of the ELF test for staging of hepatic fibrosis. APPROACH & RESULTS: Searches of PubMed and EMBASE were conducted between October 2020 and November 2021 to identify studies reporting the diagnostic accuracy of the ELF test compared to histology in liver disease patients. QUADAS-2 was used to assess risk of bias in each study. Meta-analysis using the multiple thresholds model described by Steinhauser S, Schumacher M, Rücker G. Modelling multiple thresholds in meta-analysis of diagnostic test accuracy studies. BMC Med. Res. Methodol. 2016;16. 10.1186/s12874-016-0196-1 allowed synthesis of 2 × 2 data at different cut-offs. Sixty-three studies were included in this review. These studies included 19,285 patients with or at risk of liver disease from viral hepatitis, Non-Alcoholic Fatty Liver Disease, Alcohol-related Liver Disease and other mixed chronic liver diseases. The prevalence of significant fibrosis, advanced fibrosis and cirrhosis was 47.5%, 39.2% and 4.4%, respectively. Cut-offs with maximal Youden index were generated with AUROC = 0.811 (95% CI: 0.736-0.870), 0.812 (95% CI: 0.758-0.856) and 0.810 (95% CI: 0.694-0.888) to detect significant fibrosis, advanced fibrosis or cirrhosis, respectively. Diagnostic accuracy of the ELF test varied between different liver diseases and cut-offs to detect each stage with 95% sensitivity or specificity were also generated. CONCLUSIONS: Meta-analysis revealed considerable variability in the ability of ELF to stage fibrosis across disease aetiologies. Research has mostly focused on viral hepatitis and NAFLD. There is currently a lack of data on the value of the ELF test in Alcohol-related liver disease and patients in primary care settings.

RESUMO

BACKGROUND: Coronary access may be challenging following transcatheter aortic valve replacement (TAVR) in the setting of transcatheter heart valve (THV) commissural misalignment. OBJECTIVES: The authors aimed to quantify the degree of commissural alignment following balloon-expandable THV implantation using a fluoroscopy-based trigonometric approach and assess its correlation with post-TAVR computed tomography (CT). METHODS: Twenty patients who had undergone both TAVR with the balloon-expandable SAPIEN 3 THV and post-TAVR CT were included in the analysis. Optimized, predeployment 3-cusp angiographic view and postdeployment angiographic view using identical fluoroscopic projections were required. The distance between the most central posterior commissural strut and the THV centerline was assessed. Commissural alignment was calculated by means of a trigonometrical approach using an arcsine function, assuming circular deployment of the THV. Commissural alignment was stratified using a 4-tier scale: aligned (0° to 15°); mildly misaligned (15° to 30°); moderately misaligned (30° to 45°), and severely misaligned (45° to 60°). RESULTS: Seven patients (35.0%) were misclassified by 1 tier, and no patient was misclassified by 2 or more tiers, with strong agreement between CT and fluoroscopy (weighted Cohen's kappa coefficient = 0.724). Correlation of the commissural offset angle determined from fluoroscopy and CT was excellent (r = 0.986; 95% CI: 0.965 to 0.995). Bland-Altman analysis demonstrated a strong agreement between both modalities with a mean difference of 0.5° (95% limits of agreement: -12.7° to 13.7°). CONCLUSIONS: The degree of commissural alignment of the balloon-expandable THV can be reliably assessed and quantified on postdeployment fluoroscopy using a standardized 3-cusp view and trigonometry-based analysis.

RESUMO

INTRODUCTION: Voluntary medical male circumcision (VMMC), an effective HIV prevention programme for men, is implemented in East and Southern Africa. Approximately 50% of VMMC clients are aged below 15 years. More targeted interventions to reach older men and others at higher short-term HIV risk are needed. METHODS: We implemented a quality improvement project testing the effectiveness of an active referral-based VMMC recruitment approach, targeting men attending STI clinics and those escorting partners to antenatal care (ANC) clinics, at Bwaila Hospital in Lilongwe, Malawi. We compared the proportions aged older than 15 years among men who received VMMC following referral from STI and ANC clinics with those among men referred from standard community mobilisation. We also analysed referral cascades to VMMC. RESULTS: In total, 330 clients were circumcised after referral from STI (242) and ANC (88) clinics, as compared with 3839 other clients attributed to standard community mobilisation. All clients from ANC and STI clinics were aged over 15 years, as compared with 69% from standard community mobilisation. STI clinics had a higher conversion rate from counselling to VMMC than ANC (12% vs 9%) and a higher contribution to total circumcisions performed at the VMMC clinic (6% vs 2%). CONCLUSIONS: Integrating VMMC recruitment and follow-up in STI and ANC clinics co-located with VMMC services can augment demand creation and targeting of men at risk of HIV, based on age and STI history. This approach can be replicated at least in similar health facilities with ANC and STI services in close proximity to VMMC service delivery.

RESUMO

Background: Despite developments in surgical techniques and medical care, people with a Fontan circulation still experience long-term complications; non-invasive therapies to optimize the circulation have not been established. Exercise intolerance affects the majority of the population and is associated with worse prognosis. Historically, people living with a Fontan circulation were advised to avoid physical activity, but a small number of heterogenous, predominantly uncontrolled studies have shown that exercise training is safe-and for unique reasons, may even be of heightened importance in the setting of Fontan physiology. The mechanisms underlying improvements in aerobic exercise capacity and the effects of exercise training on circulatory and end-organ function remain incompletely understood. Furthermore, the optimal methods of exercise prescription are poorly characterized. This highlights the need for large, well-designed, multi-center, randomized, controlled trials. Aims and Methods: The Fontan Fitness Intervention Trial (F-FIT)-a phase III clinical trial-aims to optimize exercise prescription and delivery in people with a Fontan circulation. In this multi-center, randomized, controlled study, eligible Fontan participants will be randomized to either a 4-month supervised aerobic and resistance exercise training program of moderate-to-vigorous intensity followed by an 8-month maintenance phase; or usual care (control group). Adolescent and adult (≥16 years) Fontan participants will be randomized to either traditional face-to-face exercise training, telehealth exercise training, or usual care in a three-arm trial with an allocation of 2:2:1 (traditional:telehealth:control). Children (<16 years) will be randomized to either a physical activity and exercise program of moderate-to-vigorous intensity or usual care in a two-arm trial with a 1:1 allocation. The primary outcome is a change in aerobic exercise capacity (peak oxygen uptake) at 4-months. Secondary outcomes include safety, and changes in cardiopulmonary exercise testing measures, peripheral venous pressure, respiratory muscle and lung function, body composition, liver stiffness, neuropsychological and neurocognitive function, physical activity levels, dietary and nutritional status, vascular function, neurohormonal activation, metabolites, cardiac function, quality of life, musculoskeletal fitness, and health care utilization. Outcome measures will be assessed at baseline, 4-months, and 12-months. This manuscript will describe the pathophysiology of exercise intolerance in the Fontan circulation and the rationale and protocol for the F-FIT.

RESUMO

The Government of Malawi's Health Sector Strategic Plan II highlights the importance of service integration; however, in practice, this has not been fully realized. We conducted a mixed methods evaluation of efforts to systematically implement integrated family planning and immunization services in all health facilities and associated community sites in Ntchisi and Dowa districts during June 2016-September 2017. Methods included secondary analysis of service statistics (pre- and postintervention), focus group discussions with mothers and fathers of children under age one, and in-depth interviews with service providers, supervisors, and managers. Results indicate statistically significant increases in family planning users and shifts in use of family planning services from health facilities to community sites. The intervention had no effect on immunization doses administered or dropout rates. According to mothers and fathers, benefits of service integration included time savings, convenience, and improved understanding of services. Provision and use of integrated services were affected by availability of human resources and commodities, community linkages, data collection procedures and availability, sociocultural barriers, organization of services, and supervision and commitment of health surveillance assistants. The integration approach was perceived to be feasible and beneficial by clients and providers.

RESUMO

BACKGROUND: Ethiopia has one of the lowest rates of facility delivery and is promoting birth preparedness among pregnant women through its community health services to increase the rate of institutional delivery and reduce maternal mortality. Observational studies of birth preparedness in Ethiopia have thus far only reported the marginal effect of birth preparedness when controlling for other factors, such as parity and education. OBJECTIVES: In this cross-sectional study, we use propensity score modeling to estimate the average population-level effect of birth preparedness on the likelihood of delivering at a facility. METHODS: We conducted secondary analysis of household survey data collected from 215 women with a recent live birth within the catchment areas of 10 semi-urban health centers. A mother was considered well prepared for birth if she reported completing four of the following six actions: identified a skilled provider, identified an institution, saved money, identified transport, prepared clean delivery materials, and prepared food. We performed unadjusted and multivariate logistic regression analyses, with and without propensity score weighting, to assess the relationship between birth preparedness and institutional delivery. FINDINGS: One hundred respondents (47%) delivered in an institution, and over two-thirds (151, 71%) were considered well prepared for birth. Institutional delivery was more common among women who were considered well prepared (57%) versus those who were considered not well prepared (19%). In the model with propensity score weighting, women who were well prepared for birth had 3.83 times higher odds of delivering at a facility (95% CI: 1.41-10.40, p-value = 0.010). CONCLUSIONS: This study contributes to existing evidence supporting the inclusion of antenatal birth preparedness counseling as a part of an antenatal care package for promoting institutional delivery. Important gaps remain in operationalizing the definition of birth preparedness and understanding the pathway from exposure to outcome.

RESUMO

Medical anthropology overwhelmingly reveals vulnerability as a problem of powerlessness. Vulnerable groups and individuals are those exposed to the pernicious effects of inequalities, injustices, and oppressive political realities. This largely pejorative stance, we argue, simplifies the place of vulnerability within human experience and in relation to the body, health and illness. By showcasing a range of interlocking vulnerabilities, this paper reveal the spectrum of positive and negative vulnerabilities that affect health and recovery. Through the concept of vulnerable articulations, this paper argues that health and illness experiences simultaneously create and require a range of different interconnected vulnerabilities, some of them harmful, and some of them life affirming. Ethnographically, this paper explore the concept of vulnerable articulations through two contrasting case studies: a group of British and New Zealand nuclear test veterans seeking compensation from the state, and clients of equine therapy in New Zealand. These case studies reveal that understanding human vulnerability requires a close attention to how people navigate between the diverse vulnerabilities that they face, and that attaining well-being often involves harnessing positive vulnerabilities in order to lessen the effects of damaging vulnerabilities.

RESUMO

BACKGROUND: Body mass index (BMI) is used to determine nutrition status in children with cystic fibrosis (CF); however, lean body mass (LBM) is more strongly associated with pulmonary function. Handgrip strength (HGS) measures muscle function and is reflective of LBM. The aims of this study were to assess relationships among HGS, nutrition status, and pulmonary function; changes in HGS posthospitalization; and any relationship between HGS and nutrient intake. METHODS: Twenty-three children with CF aged 6-18 years participated. BMI z scores, nutrition risk scores, and pulmonary function were assessed about 5 months before, days 5-7 of hospitalization, and about 6 weeks posthospitalization. HGS z scores and arm anthropometrics were measured during and after hospitalization. Nutrient intakes were assessed during hospitalization. RESULTS: Mean HGS z score at hospitalization was -1.95 ± 0.92 and posthospitalization was -1.59 ± 1.06 (P = .007). Mean BMI z score prehospitalization was -0.17 ± 0.63, at hospitalization was -0.09 ± 0.64, and posthospitalization was 0.06 ± 0.54 (P = .065). Mean forced expiratory volume in 1 second (FEV1 ) prehospitalization was 93.52 ± 17.35, at hospitalization was 85.65 ± 21.57, and posthospitalization was 95.63 ± 18.18 (P = .001). No significant relationship was found between HGS z scores and BMI z scores (P = .892) or HGS z scores and FEV1 (P = .340). CONCLUSIONS: HGS z scores and FEV1 significantly increased at follow-up. HGS z scores were lower than the standard even though mean BMI z scores classified participants as normal nutrition status.

RESUMO

A comprehensive review of the literature was completed to investigate college student-athletes' perceptions regarding the long-term effects of concussions. Based on the findings, it was determined that there is a need for more education among student-athletes regarding this topic. This was a quantitative, cross-sectional, nonexperimental study with a descriptive design. A survey with 7 demographic and 17 Likert-type statements was collected from 100 student-athletes in a Midwestern college at their specified team practice sites for data collection.

RESUMO

BACKGROUND: Disrespect and abuse of women during institutional childbirth services is one of the deterrents to utilization of maternity care services in Ethiopia and other low- and middle-income countries. This paper describes the prevalence of respectful maternity care (RMC) and mistreatment of women in hospitals and health centers, and identifies factors associated with occurrence of RMC and mistreatment of women during institutional labor and childbirth services. METHODS: This study had a cross sectional study design. Trained external observers assessed care provided to 240 women in 28 health centers and hospitals during labor and childbirth using structured observation checklists. The outcome variable, providers' RMC performance, was measured by nine behavioral descriptors. The outcome, any mistreatment, was measured by four items related to mistreatment of women: physical abuse, verbal abuse, absence of privacy during examination and abandonment. We present percentages of the nine RMC indicators, mean score of providers' RMC performance and the adjusted multilevel model regression coefficients to determine the association with a quality improvement program and other facility and provider characteristics. RESULTS: Women on average received 5.9 (66%) of the nine recommended RMC practices. Health centers demonstrated higher RMC performance than hospitals. At least one form of mistreatment of women was committed in 36% of the observations (38% in health centers and 32% in hospitals). Higher likelihood of performing high level of RMC was found among male vs. female providers ([Formula: see text], p = 0.012), midwives vs. other cadres ([Formula: see text], p = 0.002), facilities implementing a quality improvement approach, Standards-based Management and Recognition (SBM-R©) ([Formula: see text], p = 0.003), and among laboring women accompanied by a companion [Formula: see text], p = 0.003). No factor was associated with observed mistreatment of women. CONCLUSION: Quality improvement using SBM-R© and having a companion during labor and delivery were associated with RMC. Policy makers need to consider the role of quality improvement approaches and accommodating companions in promoting RMC. More research is needed to identify the reason for superior RMC performance of male providers over female providers and midwives compared to other professional cadre, as are longitudinal studies of quality improvement on RMC and mistreatment of women during labor and childbirth services in public health facilities.

RESUMO

BACKGROUND: The Standards Based Management and Recognition (SBM-R©) approach to quality improvement has been implemented in Ethiopia to strengthen routine maternal and newborn health (MNH) services. This evaluation assessed the effect of the intervention on MNH providers' performance of routine antenatal care (ANC), uncomplicated labor and delivery and immediate postnatal care (PNC) services. METHODS: A post-only evaluation design was conducted at three hospitals and eight health centers implementing SBM-R and the same number of comparison health facilities. Structured checklists were used to observe MNH providers' performance on ANC (236 provider-client interactions), uncomplicated labor and delivery (226 provider-client interactions), and immediate PNC services in the six hours after delivery (232 provider-client interactions); observations were divided equally between intervention and comparison groups. Main outcomes were provider performance scores, calculated as the percentage of essential tasks in each service area completed by providers. Multilevel analysis was used to calculate adjusted mean percentage performance scores and standard errors to compare intervention and comparison groups. RESULTS: There was no statistically significant difference between intervention and comparison facilities in overall mean performance scores for ANC services (63.4% at intervention facilities versus 61.0% at comparison facilities, p = 0.650) or in any specific ANC skill area. MNH providers' overall mean performance score for uncomplicated labor and delivery care was 11.9 percentage points higher in the intervention than in the comparison group (77.5% versus 65.6%; p = 0.002). Overall mean performance scores for immediate PNC were 22.2 percentage points higher at intervention than at comparison facilities (72.8% versus 50.6%; p = 0.001); and there was a significant difference of 22 percentage points between intervention and comparison facilities for each PNC skill area: care for the newborn and health check for the mother. CONCLUSIONS: The SBM-R quality improvement intervention made a significant positive impact on MNH providers' performance during labor and delivery and immediate PNC services, but not during ANC services. Scaling up the intervention to other facilities and regions may increase the availability of good quality MNH services across Ethiopia. The findings will also guide implementation of the government's five-year (2015-2020) health sector transformation plan and health care quality strategies needed to meet the country's MNH goals.

RESUMO

PURPOSE: Realizing aspirations for meeting the global reproductive, maternal, newborn, and child health goals depends not only on increasing the numbers but also on improving the capability of midwifery workforce. We conducted a task analysis study to identify the needs for strengthening the midwifery workforce in Ethiopia. METHODS: We conducted a cross-sectional study of recently qualified midwives in Ethiopia. Purposively selected participants from representative geographic and practice settings completed a self-administered questionnaire, making judgments about the frequency of performance, criticality, competence, and location of training for a list of validated midwifery tasks. Using Statistical Package for the Social Sciences, Version 20, we computed the percentages and averages to describe participant and practice characteristics. We identified priority preservice education gaps by considering the tasks least frequently learned in preservice, most frequently mentioned for not being trained, and had the highest not capable response. Identification of top priorities for in-service training considered tasks with highest "not capable" and "never" done responses. We determined the licensing exam blueprint by weighing the composite mean scores for frequency and criticality variables and expert rating across practice categories. RESULTS: One hundred and thirty-eight midwives participated in the study. The majority of respondents recognized the importance of midwifery tasks (89%), felt they were capable (91.8%), reported doing them frequently (63.9%), and learned them during preservice education (56.3%). We identified competence gaps in tasks related to obstetric complications, gynecology, public health, professional duties, and prevention of mother to child transmission of HIV. Moreover, our study helped to determine composition of the licensing exam for university graduates. CONCLUSION: The task analysis indicates that midwives provide critical reproductive, maternal, newborn, and child health care services and supports continuing investment in this cadre. However, there were substantial competence gaps that limit their ability to accelerate progress toward health development goals. Moreover, basing the licensure exam on task analysis helped to ground it in national practice priorities.

RESUMO

PROBLEM: The shortage of doctors in Liberia limits the provision of comprehensive emergency obstetric and neonatal care. APPROACH: In a pilot project, two midwives were trained in advanced obstetric procedures and in the team approach to the in-hospital provision of advanced maternity care. The training took two years and was led by a Liberian consultant obstetrician with support from international experts. LOCAL SETTING: The training took place in CB Dunbar Maternity Hospital. This rural hospital deals with approximately 2000 deliveries annually, many of which present complications. In February 2015 there were just 117 doctors available in Liberia. RELEVANT CHANGES: In the first 18 months of training, the trainees were involved with 236 caesarean sections, 35 manual evacuations of products of conception, 25 manual removals of placentas, 21 vaginal breech deliveries, 14 vacuum deliveries, four repairs of ruptured uteri, the management of four cases of shoulder dystocia, three hysterectomies, two laparotomies for ruptured ectopic pregnancies and numerous obstetric ultrasound examinations. The trainees also managed 41 cases of eclampsia or severe pre-eclampsia, 25 of major postpartum haemorrhage and 21 of shock. Although, initially they only assisted senior doctors, the trainees subsequently progressed from direct to indirect supervision and then to independent management. LESSONS LEARNT: To compensate for a shortage of doctors able to undertake comprehensive emergency obstetric and neonatal care, experienced midwives can be taught to undertake advanced obstetric care and procedures. Their team work with doctors can be particularly valuable in rural hospitals in resource-poor countries.

RESUMO

BACKGROUND: Midwifery support and care led by midwives is the most appropriate strategy to improve maternal and newborn health. The Government of Ethiopia has recently improved the availability of midwives by scaling up pre-service education. However, the extent to which graduating students acquire core competencies for safe and effective practice is not known. The purpose of this study was to evaluate the quality of midwifery education by assessing the competence of graduating midwifery students. METHODS: We conducted a cross-sectional study to assess the competence of students who completed basic midwifery education in Ethiopia in 2013. We interviewed students to obtain their perceptions of the sufficiency and quality of teachers and educational resources and processes. We assessed achievement of essential midwifery competencies through direct observation, using a 10-station Objective Structured Clinical Examination (OSCE). We calculated average percentage scores of performance for each station and an average summary score for all stations. Chi-square test, independent sample t test, and linear regression analysis were used to assess the statistical significance of differences and associations. RESULTS: We assessed 484 graduating students from 25 public training institutions. Majority of students rated the learning environment unfavorably on 8 out of 10 questions. Only 32 % of students managed 20 or more births during training, and just 6 % managed 40 or more births. Students' overall average competence score was 51.8 %; scores ranged from 32.2 % for manual vacuum aspiration to 69.4 % for active management of the third stage of labor. Male gender, reporting sufficient clinical experience, and managing greater numbers of births during training were significant predictors of higher competence scores. CONCLUSIONS: The quality of pre-service midwifery education needs to be improved, including strengthening of the learning environment and quality assurance systems. In-service training and mentoring to fill competence gaps of new graduates is also essential.

RESUMO

BACKGROUND: Reducing turnover is essential to address health worker shortages in the public sector and improve the quality of services. This study examines factors associated with Ethiopian nurses' intention to leave their jobs. METHODS: Survey respondents (a sample of 425 nurses at 122 facilities) rated the importance of 20 items in decisions to leave their jobs and reported whether they intended to leave their jobs in the next year. Descriptive and inferential statistical analyses were used to identify predictors of nurses' intentions to leave their jobs. RESULTS: Half (50.2%) the nurses said they intended to leave their jobs in the next year. A multivariate analysis identified three significant predictors of nurses' intention to leave their jobs: holding a university degree rather than a diploma (adjusted odds ratio (OR)=2.246, 95% confidence interval (CI)=1.212, 4.163; p<0.01), having worked fewer years in the public health system (adjusted OR=0.948, 95% CI=0.914, 0.982; p<0.01) and rating the importance of limited opportunities for professional development more highly (adjusted OR=1.398, 95% CI=1.056, 1.850; p<0.02). CONCLUSION: Interventions to increase the retention of nurses at public health facilities in Ethiopia should target young nurses who are completing their compulsory service obligation and nurses with a university degree. They should include both non-financial and financial incentives.

RESUMO

OBJECTIVE: To test the safety, acceptability, feasibility, and effectiveness of community-based education and distribution of misoprostol for prevention of postpartum hemorrhage at home birth in Afghanistan. METHODS: A nonrandomized experimental control design in rural Afghanistan. RESULTS: A total of 3187 women participated: 2039 in the intervention group and 1148 in the control group. Of the 1421 women in the intervention group who took misoprostol, 100% correctly took it after birth, including 20 women with twin pregnancies. Adverse effect rates were unexpectedly lower in the intervention group than in the comparison group. Among women in the intervention group, 92% said they would use misoprostol in their next pregnancy. In the intervention area where community-based distribution of misoprostol was introduced, near-universal uterotonic coverage (92%) was achieved compared with 25% coverage in the control areas. CONCLUSION: In Afghanistan, community-based education and distribution of misoprostol is safe, acceptable, feasible, and effective. This strategy should be considered for other countries where access to skilled attendance is limited.
