RESUMEN

BACKGROUND: Skin physiology seems to be influenced by dietary choices and body composition, although links between these factors remain poorly characterised. In the present manuscript, we elaborate on the potential relationships among food groups, body composition and skin physiology in omnivores and vegetarians. MATERIAL AND METHODS: This cross-sectional observational study involved 181 participants, 129 omnivores and 52 vegetarians. The main functions of the skin measured in our laboratory were transepidermal water loss, deep and superficial epidermal hydration, skin elasticity, and carotenoid content. Skin variables obtained from different body regions were made comparable by a new Proportional Skin Index calculated to respect their relative representativity. RESULTS: No statistical differences were found when comparing both groups' body composition and skin variables from different body regions, with the exception of the skin carotenoid content significantly higher in the vegetarian group (p < 0.001). CONCLUSION: Although dietary patterns significantly differed between groups, with vegetarians consuming fewer animal-derived products and more plant-based foods, multiple linear regression analysis revealed no differences or association between the dietary pattern and the skin physiology. These findings highlight the need for further research to elucidate the specific impact of diet and food groups and body composition on skin physiology.

RESUMEN

BACKGROUND: Lithuania has one of the highest averages in the European Union when it comes to psychological and/or economic intimate partner violence (PE-IPV). IPV survivors are several times more likely to have mental health conditions than those without IPV experiences. The aim of this article is to study the prevalence, characteristics and attitudes of PE-IPV survivors in Lithuania, and the predictors of them accessing mental health services. METHODS: A cross-sectional study based on a national survey representative of the adult population. The survey was implemented by a third-party independent market research company employing an online survey panel. Logistic regression models were used in the analysis. RESULTS: Almost 50% of women in Lithuania experience PE-IPV. Females are significantly more likely to experience it than males. The vast majority of women find PE-IPV unacceptable; however, only one-third of survivors seek any type of help. Only one-tenth approach mental health services, with divorcees being at higher odds of doing so. CONCLUSIONS: Further research is needed to explore predictors and contextual factors of why IPV survivors seek mental healthcare, or not. Policy implications include the need to eliminate IPV and mental health stigma; develop accessible mental health services and effective treatment approaches.

RESUMEN

BACKGROUND: Women in Mozambique are often disempowered when it comes to making decisions concerning their lives, including their bodies and reproductive options. This study aimed to explore the views of women in Mozambique about key elements of empowerment for reproductive decisions and the meanings they attach to these elements. METHODS: Qualitative in-depth interviews were undertaken with 64 women of reproductive age (18-49 years) in two provinces in Mozambique. Participants were recruited through convenience sampling. Data collection took place between February and March 2020 in Maputo city and Province, and during August 2020 in Nampula Province. A thematic analysis was performed. RESULTS: Women described crucial elements of how power is exerted for reproductive choices. These choices include the ability to plan the number and timing of pregnancies and the ability either to negotiate with sexual partners by voicing choice and influencing decisions, or to exercise their right to make decisions independently. They considered that women with empowerment had characteristics such as independence, active participation and being free. These characteristics are recognized key enablers for the process of women's empowerment. CONCLUSIONS: This study's findings contribute to an expanded conceptualization and operationalization of women's sexual and reproductive empowerment by unveiling key elements that need to be considered in future research and approaches to women's empowerment. Furthermore, it gave women the central role and voice in the research of empowerment's conceptualization and measurement where women's views and meanings are seldom considered.


Women who are empowered seem to make better health decisions for themselves. Nevertheless, women's views about and understanding of empowerment are seldom considered in the study of empowerment and its definitions. In this study we explore how women in Mozambique view, understand and experience empowerment, i.e., gaining power and control in the household, and specifically around decision-making processes concerning their reproductive lives. A total of 64 adult women were interviewed in rural and urban areas within two provinces of Mozambique. Through the data analysis, we identified key characteristics of the empowerment process that Mozambican women perceived to be of relevance in their context. Women who have power were perceived as financially and socially independent, free to choose their own pathway, and be active participants in the household decision-making process. In reproductive decisions, women show power through the ability to negotiate with their partner, or by making sole decisions and by planning the number of pregnancies and the size of the family. The elements identified provide important information for improving the definition and the measurement of empowerment in Mozambique, as well as for the support of women in their pathways to empowerment within this context.

RESUMEN

BACKGROUND: Long-term success of peritoneal dialysis relies on the integrity of the peritoneal membrane. This proof-of-concept study addressed the hypothesis that fibrosis is already present in the membrane at pre-dialysis and that the membrane status is related to the individual's uraemic fingerprint. METHODS: A clinical-mechanistic, transversal, single-centre study was conducted. Pre-dialysis peritoneal biopsies were scored considering the submesothelial compact zone thickness (STM), vasculopathy and inflammation. We investigated if the membrane status could be inferred from a panel of proteins (α-Klotho, Galectin-3, FGF21, FGF23, Tweak, TNFα and hsPCR) in blood. RESULTS: A total 58 incident patients aged 56 ± 15 years old were included, 31% female, 55% hypertension, 29% diabetic and 24% obese. Person-to-person STM was found to be highly variable and 38% of patients were fibrosis positive. Both α-Klotho (Spearman r = -.7491, p < 0.001) and FGF21 (Spearman r = -.5102, p < 0.001) were negatively associated with STM. α-Klotho, but not FGF21, was able to discriminate fibrosis from nonfibrosis with/without inflammation and vasculopathy. PLS models identified α-Klotho as the protein most relevant for fibrosis. α-Klotho was independently associated with fibrosis of the peritoneal membrane (OR = .991 (.896-.997), p = 0.002). CONCLUSION: Before the start of dialysis in incident patients, some patients already present fibrosis of the peritoneal membrane and other patients do not. Our findings suggest that α-Klotho may be implicated in fibrosis of the peritoneal membrane.

RESUMEN

BACKGROUND: Midwives are essential providers of primary health care and can play a major role in the provision of health care that can save lives and improve sexual, reproductive, maternal, newborn and adolescent health outcomes. One way for midwives to deliver care is through midwife-led birth centres (MLBCs). Most of the evidence on MLBCs is from high-income countries but the opportunity for impact of MLBCs in low- and middle-income countries (LMICs) could be significant as this is where most maternal and newborn deaths occur. The aim of this study is to explore MLBCs in four low-to-middle income countries, specifically to understand what is needed for a successful MLBC. METHODS: A descriptive case study design was employed in 4 sites in each of four countries: Bangladesh, Pakistan, South Africa and Uganda. We used an Appreciative Inquiry approach, informed by a network of care framework. Key informant interviews were conducted with 77 MLBC clients and 33 health service leaders and senior policymakers. Fifteen focus group discussions were used to collect data from 100 midwives and other MLBC staff. RESULTS: Key enablers to a successful MLBC were: (i) having an effective financing model (ii) providing quality midwifery care that is recognised by the community (iii) having interdisciplinary and interfacility collaboration, coordination and functional referral systems, and (iv) ensuring supportive and enabling leadership and governance at all levels. CONCLUSION: The findings of this study have significant implications for improving maternal and neonatal health outcomes, strengthening healthcare systems, and promoting the role of midwives in LMICs. Understanding factors for success can contribute to inform policies and decision making as well as design tailored maternal and newborn health programmes that can more effectively support midwives and respond to population needs. At an international level, it can contribute to shape guidelines and strengthen the midwifery profession in different settings.

RESUMEN

OBJECTIVES: Our objective was to investigate changes in specific generic health-related quality-of-life (HRQoL) domains achieved by rhinoplasty, to investigate whether modifications of somatic-, psychologic-, and social-related HRQoL domains are different in patients with functional or aesthetic motivation for rhinoplasty, and to investigate if HRQoL changes are related to a functional or an aesthetic nasal improvement. STUDY DESIGN: This was a prospective study with 1 year of follow-up. METHODS: Fifty-four consecutive Caucasian patients submitted to rhinoplasty were evaluated with 36-item Short Form Health Survey (SF-36) and EuroQuality-of-Life 5 Domain (EQ-5D) questionnaires. To correlate changes in generic HRQoL with functional and aesthetic modifications achieved by rhinoplasty, evaluation of patients also included assessment of Peak Nasal Inspiratory Flow and Nasal Obstruction Symptom Evaluation, Visual Analogue Scale for nasal airway obstruction (NAO), and Rhinoplasty Outcome Evaluation scores.Modifications in each generic HRQoL health-domain were analyzed to investigate the possible relation with motivation for surgery and with functional or aesthetic improvement. RESULTS: There was a significant improvement in EQ-5D (p < 0.001), EQ-5D VAS (p = 0.002) and in the SF-36 domains of general health (p < 0.001), energy (p < 0.001), physical functioning (p < 0.001), physical limitation (p = 0.005), pain (p = 0.003), and well-being (p = 0.018). Improvement was significant in groups of patients with NAO or in whom a septoplasty was performed and was associated with patient-reported functional improvement. There was a significant improvement in health change (p < 0.001), verified in all groups of patients. CONCLUSIONS: This prospective study with long-term results demonstrates that rhinoplasty significantly improves most domains of generic HRQoL. This improvement is associated with patient-reported functional improvement. Emotional limitation and social functioning are not significantly changed by rhinoplasty. LEVEL OF EVIDENCE: IV.

RESUMEN

Peritoneal membrane status, clinical data and aging-related molecules were investigated as predictors of long-term peritoneal dialysis (PD) outcomes. A 5-year prospective study was conducted with the following endpoints: (a) PD failure and time until PD failure, (b) major cardiovascular event (MACE) and time until MACE. A total of 58 incident patients with peritoneal biopsy at study baseline were included. Peritoneal membrane histomorphology and aging-related indicators were assessed before the start of PD and investigated as predictors of study endpoints. Fibrosis of the peritoneal membrane was associated with MACE occurrence and earlier MACE, but not with the patient or membrane survival. Serum α-Klotho bellow 742 pg/mL was related to the submesothelial thickness of the peritoneal membrane. This cutoff stratified the patients according to the risk of MACE and time until MACE. Uremic levels of galectin-3 were associated with PD failure and time until PD failure. This work unveils peritoneal membrane fibrosis as a window to the vulnerability of the cardiovascular system, whose mechanisms and links to biological aging need to be better investigated. Galectin-3 and α-Klotho are putative tools to tailor patient management in this home-based renal replacement therapy.

RESUMEN

BACKGROUND: The treatment gap for mental disorders remains a challenge worldwide. Identifying reasons for nontreatment may contribute to reducing this gap. AIMS: To evaluate sociodemographic and clinical factors associated with use and barriers to treatment in Portugal. METHOD: Data from the 2009 National Mental Health Survey were used. Participants reported 12-month treatment and reasons for nontreatment. Logistic regression models analysed the association between sociodemographic (education; employment; income; marital status) and clinical variables (mental disorder diagnosis; disability) with treatment and type of barriers (low perceived need; structural; attitudinal). RESULTS: The majority of participants with a mental disorder was not treated. Treatment was more common among participants with mood disorders (OR = 4.19; 95% CI: 2.72-6.46), and disability (OR = 2.43; 95% CI: 1.33-4.46), and less common among single participants (OR = 0.38; 95% CI: 0.20-0.70) and those with basic/secondary education (OR = 0.42; 95% CI: 0.24-0.73). Attitudinal barriers were more likely among participants with none/primary (OR = 2.90; 95% CI: 1.42-5.90) and basic/secondary education (OR = 1.70; 95% CI: 1.01-2.85), and less likely among those with substance use disorders (OR = 0.27; 95% CI: 0.10-0.70). Low perceived need was higher among single people (OR = 1.77; 95% CI: 1.01-3.08), and lower among those with anxiety (OR = 0.50; 95% CI: 0.28-0.90) and mood disorders (OR = 0.16; 95% CI: 0.09-0.30). Unemployed participants had higher odds of reporting structural barriers (OR = 3.76; 95% CI: 1.29-10.92). CONCLUSIONS: This study identifies factors associated with nontreatment, providing useful evidence to develop policies and effective interventions.

RESUMEN

BACKGROUND: Evidence has shown that the sensation of nasal breathing is related to variations in nasal mucosa temperature produced by airflow. An appropriate nasal airflow is necessary for changing mucosal temperature. Therefore, the correlation between objective measurements of nasal airflow and patient-reported evaluation of nasal breathing should be dependent on the level of nasal airflow. OBJECTIVES: To find if the correlation between patient-reported assessment of nasal breathing and objective measurement of nasal airflow is dependent on the severity of symptoms of nasal obstruction or on the level of nasal airflow. METHODS: The airway of 79 patients was evaluated using NOSE score and peak nasal inspiratory flow (PNIF). Three subgroups were created based on NOSE and three subgroups were created based on PNIF level to find if correlation was dependent on nasal symptoms or airflow. RESULTS: The mean value of PNIF for the 79 patients was 92.6 L/min (SD 28.1 L/min). The mean NOSE score was 48.4 (SD 24.4). The correlation between PNIF and NOSE was statistically significant (P = .03), but with a weak association between the two variables (r = -.248). Evaluation of correlation based on symptoms demonstrated a weak or very weak association in each subgroup (r = -.250, r = -.007, r = -.104). Evaluation of correlation based on nasal airflow demonstrated a very weak association for the subgroups with middle-level and high PNIF values (r = -.190, r = -.014), but a moderate association for the subgroup with low PNIF values (r = -.404). CONCLUSIONS: This study demonstrated a weak correlation between NOSE scores and PNIF values in patients non-selected according to symptoms of nasal obstruction or to airflow. It demonstrated that patients with symptoms of nasal obstruction have different levels of nasal airflow and that low nasal airflow prevents the sensation of good nasal breathing. Therefore, patients with symptoms of nasal obstruction may require improving nasal airflow to improve nasal breathing sensation.

RESUMEN

BACKGROUND: Research suggests that economic recessions might be associated with a higher use of psychotropic drugs, but literature is scarce and contradictory in identifying the most vulnerable groups. This study aims to assess possible changes in the use of psychotropic drugs due to the economic recession in Portugal, by comparing self-reported consumption in 2008/09 and 2015/16. METHODS: Data from the World Mental Health Survey Initiative Portugal (2008/09) and the National Mental Health Survey Follow-Up (2015/16) were used (n = 911). McNemar's tests were performed to estimate changes in consumption of any psychotropic drug and of antidepressants, anxiolytics, and hypnotics/sedatives. Multiple Generalised Estimating Equations models with interaction effects were used to estimate the population odds of consuming psychotropic drugs according to year, gender and age. RESULTS: An increase of 6.74% was estimated in the consumption of psychotropic drugs from 2008/09 to 2015/16. Population odds of consuming any psychotropic drugs in 2015/16 were estimated to be 1.5 times higher than in 2008/09 (OR = 1.50;95%CI:1.13-2.01), particularly for hypnotics/sedatives (OR = 1.60;95%CI:1.14-2.25). Women and older individuals presented higher odds of consuming any psychotropic drugs (OR = 2.79;95%CI:2.03-3.84, and OR = 1.80;95%CI:1.28-2.54), after adjusting for year of assessment and education. However, when evaluating the interaction effect of the year with gender and age, men and younger individuals reported higher odds of consuming any psychotropic drugs in 2015/16, when compared to 2008/09 (OR = 1.85;95%CI:1.08-3.17, and OR = 1.95;95%CI:1.32-2.90, respectively). CONCLUSIONS: The findings indicate that the period of economic recession was associated with an increased risk of psychotropic drugs use in Portugal. Consumption of psychotropic drugs remained higher among women and older individuals, but the results suggest that the economic crisis had a disproportionate impact on men and younger individuals. This identification of the most vulnerable population groups is useful to design effective and targeted public health interventions aimed at alleviating the effects of economic recessions.

RESUMEN

BACKGROUND: Improving the shape and contour of the nasal tip is a major goal in rhinoplasty. Extreme bulbosity and parenthesis deformity of the nasal tip are both frequently encountered. However, the underlying anatomical features that cause this kind of tip deformity are still not fully understood. OBJECTIVES: To evaluate the relation between the shape of the nasal tip and the anatomical position, orientation and shape of the lateral crura of the lower lateral cartilages and to estimate the incidence of cephalic malposition of lateral crura in Caucasian noses. MATERIALS AND METHODS: Nineteen Caucasian cadaver noses were studied, and the alar cartilages were measured and evaluated using a standardized method. RESULTS: Fourteen of the total 38 lateral crura evaluated had cephalic malposition (long axis angle with the midline equal to or less than 30°). Of the nasal tips classified as having parenthesis deformity, 84.6% had cephalic malposition of lateral crura and 46.2% had convex lateral crura. Vertical orientation of the short axis of the lateral crura was no more common in noses with parenthesis deformity of the nasal tip than in other kinds of nasal tip. CONCLUSIONS: The incidence of cephalic malposition of the lateral crura in this series of Caucasian noses was 36.8%. There was a statistically significant association between parenthesis deformity of the nasal tip and cephalic malposition of the lateral crura, as well as with convex shape of the lateral crura. No statistically significant association was found between the sagittal angle of the lateral crura and the type of nasal tip.

RESUMEN

Composting is a process recommended as a way to recycle the organic part of the solid waste in which several micro and macroorganisms act as decomposers of the organic matter, in a process that takes around 120 days and faces roughly three different phases. Because we do not know the community of arthropods associated with the compost produced in one of the biggest landfills placed in Brazil, here we collected and identified the community of arthropods present in each phase of the organic compost. Our hypothesis is that the abundance and diversity of arthropods are different within each phase of the compost and we hope to find particular groups of arthropods that can be used as indicator of specific phases. In total, we identified the taxa of 1204 arthropods (insects, arachnidan and diplopods). We found that diversity and abundancy of arthropods were indeed different for each maturation phase of the compost, but we did not find families that are good indicators of each phase. In addition, to be certain about the safety of the compost produced, we investigated the presence of microorganisms in the final product and we found considerable levels of Escherichia coli and Enterococcus faecalis in some samples. Finally, we argue that the presence of these macro and microorganisms during the process may be beneficial or harmful. Since their presence decreased greatly by the end of the process, we acknowledge that composting works efficiently as a way to recycle the organic part of the waste generated in Brazil.

RESUMEN

Plexiform fibrohistiocytic tumor is an uncommon soft tissue neoplasm of intermediate malignancy, most frequently occurring as a painless, slow-growing nodule that shows a distinct predilection for children and young adults. We report a healthy 11-year-old boy presenting with a 1-year history of an asymptomatic cutaneous nodule on his left shoulder. Histopathological and immunohistochemical analysis confirmed a diagnosis of plexiform fibrohistiocytic tumor. Despite following a usually benign clinical course, this neoplasm is prone to frequent local recurrence and occasional metastatic ability. It should be considered in the differential diagnosis of an enlarging nodule in pediatric patients.

RESUMEN

Exposure to chronic stress is frequently accompanied by cognitive and affective disorders in association with neurostructural adaptations. Chronic stress was previously shown to trigger Alzheimer's-like neuropathology, which is characterized by Tau hyperphosphorylation and missorting into dendritic spines followed by memory deficits. Here, we demonstrate that stress-driven hippocampal deficits in wild-type mice are accompanied by synaptic missorting of Tau and enhanced Fyn/GluN2B-driven synaptic signaling. In contrast, mice lacking Tau [Tau knockout (Tau-KO) mice] do not exhibit stress-induced pathological behaviors and atrophy of hippocampal dendrites or deficits of hippocampal connectivity. These findings implicate Tau as an essential mediator of the adverse effects of stress on brain structure and function.

RESUMEN

Systemic immunoglobulin light chain amyloidosis is the most common and severe type of amyloidosis. There is an abnormal fibrillary protein deposition in tissues that leads to progressive and irreversible organ dysfunction. The most commonly affected organs are kidney and heart. Although rare, cutaneous manifestations may be the first clinical sign of the disease and usually present as hemorrhagic lesions, such as purpura, petechiae, and ecchymosis. We present a 71-year-old man that presented to our department because of exuberant purpuric plaques in the anogenital area as the first manifestation of an amyloid light-chain (AL) amyloidosis. The multi-organ involvement in addition to rapid clinical deterioration precipitated the patient's death four months later.

RESUMEN

BACKGROUND: Mental disorders are a major cause of disability with impacts on daily functioning and quality of life, which has been associated with socioeconomic disadvantage. The present study aims to assess how socioeconomic position is related to the disability reported by people with mental disorders, using data from the World Mental Health Survey (WMHS) Initiative Portugal. METHODS: Using data from the Portuguese Mental Health Survey, a nationally representative cross-sectional study (n = 3849), several logistic regression models with interaction terms were performed to evaluate the effect of different indicators of socioeconomic position on the disability reported by people with any mental disorder (any 12-month mood or anxiety disorder). Odds ratios were estimated at the specific values of the main effects and interaction terms between the presence of any mental disorder and education, employment status, self-perceived financial deprivation and subjective social status. RESULTS: The prevalence rate of any mood or anxiety disorder was 21.0% (n = 788), among which 14.7% (n = 115) reported disability. The results show that among people with any 12-month mental disorder, those in the employment category of "retired or others" had two times higher odds of reporting disability (OR = 2.19; 95%CI: 1.06-4.48) when compared to participants categorized as "working". Likewise, individuals with financial deprivation had two times higher odds of reporting disability when compared to those non-financially deprived (OR = 2.36; 95%CI: 1.31-4.24). The odds ratios obtained for the specific years of education evaluated were not statistically significant but seem to suggest an educational gradient. CONCLUSIONS: The findings of this study indicate that the disability reported by people with mental disorders varies according to socioeconomic position and draw attention to the need to develop policies to address these inequalities.

RESUMEN

Tau protein in dendrites and synapses has been recently implicated in synaptic degeneration and neuronal malfunction. Chronic stress, a well-known inducer of neuronal/synaptic atrophy, triggers hyperphosphorylation of Tau protein and cognitive deficits. However, the cause-effect relationship between these events remains to be established. To test the involvement of Tau in stress-induced impairments of cognition, we investigated the impact of stress on cognitive behavior, neuronal structure, and the synaptic proteome in the prefrontal cortex (PFC) of Tau knock-out (Tau-KO) and wild-type (WT) mice. Whereas exposure to chronic stress resulted in atrophy of apical dendrites and spine loss in PFC neurons as well as significant impairments in working memory in WT mice, such changes were absent in Tau-KO animals. Quantitative proteomic analysis of PFC synaptosomal fractions, combined with transmission electron microscopy analysis, suggested a prominent role for mitochondria in the regulation of the effects of stress. Specifically, chronically stressed animals exhibit Tau-dependent alterations in the levels of proteins involved in mitochondrial transport and oxidative phosphorylation as well as in the synaptic localization of mitochondria in PFC. These findings provide evidence for a causal role of Tau in mediating stress-elicited neuronal atrophy and cognitive impairment and indicate that Tau may exert its effects through synaptic mitochondria.

RESUMEN

BACKGROUND: In a post-2015 development agenda, achieving Universal Health Coverage (UHC) for women and newborns will require a fit-for-purpose and fit-to-practice sexual, reproductive, maternal, adolescent and newborn health (SRMNAH) workforce. The aim of this paper is to explore barriers, challenges and solutions to the availability, accessibility, acceptability and quality (AAAQ) of SRMNAH services and workforce. METHODS: The State of the World's Midwifery report 2014 used a broad definition of midwifery ("the health services and health workforce needed to support and care for women and newborns") and provided information about a wide range of SRMNAH workers, including doctors, midwives, nurses and auxiliaries. As part of the data collection, 36 out of the 73 participating low- and middle-income countries conducted a one-day workshop, involving a range of different stakeholders. Participants were asked to discuss barriers to the AAAQ of SRMNAH workers, and to suggest strategies for overcoming the identified barriers. The workshop was facilitated using a discussion guide, and a rapporteur took detailed notes. A content analysis was undertaken using N-Vivo software and the AAAQ model as a framework. RESULTS: Across the 36 countries, about 800 participants attended a workshop. The identified barriers to AAAQ of SRMNAH workers included: insufficient size of the workforce and inequity in its distribution, lack of transportation, user fees and out of pocket payments. In some countries, respondents felt that women mistrusted the workforce, and particularly midwives, due to cultural differences, or disrespectful behaviour towards service users. Quality of care was undermined by a lack of supplies/equipment and inadequate regulation. Against these, countries identified a set of solutions including adequate workforce planning supported by a fast and equitable deployment system, aligned with the principles of UHC. Acceptability and quality could be improved with the provision of respectful care as well as strategies to improve education and regulation. CONCLUSIONS: The number and scale of the barriers still needing to be addressed in these 36 countries was significant. Adequate planning and policies to support the development of the SRMNAH workforce and its equitable distribution are a priority. Enabling strategies need to be put in place to improve the status and recognition of midwives, whose role is often undervalued.

RESUMEN

BACKGROUND: Attrition or losses from the health workforce exacerbate critical shortages of health workers and can be a barrier to countries reaching their universal health coverage and equity goals. Despite the importance of accurate estimates of the attrition rate (and in particular the voluntary attrition rate) to conduct effective workforce planning, there is a dearth of an agreed definition, information and studies on this topic. METHODS: We conducted a rapid review of studies published since 2005 on attrition rates of health workers from the workforce in different regions and settings; 1782 studies were identified, of which 51 were included in the study. In addition, we analysed data from the State of the World's Midwifery (SoWMy) 2014 survey and associated regional survey for the Arab states on the annual voluntary attrition rate for sexual, reproductive, maternal and newborn health workers (mainly midwives, doctors and nurses) in the 79 participating countries. RESULTS: There is a diversity of definitions of attrition and barely any studies distinguish between total and voluntary attrition (i.e. choosing to leave the workforce). Attrition rate estimates were provided for different periods of time, ranging from 3 months to 12 years, using different calculations and data collection systems. Overall, the total annual attrition rate varied between 3 and 44% while the voluntary annual attrition rate varied between 0.3 to 28%. In the SoWMy analysis, 49 countries provided some data on voluntary attrition rates of their SRMNH cadres. The average annual voluntary attrition rate was 6.8% across all cadres. CONCLUSION: Attrition, and particularly voluntary attrition, is under-recorded and understudied. The lack of internationally comparable definitions and guidelines for measuring attrition from the health workforce makes it very difficult for countries to identify the main causes of attrition and to develop and test strategies for reducing it. Standardized definitions and methods of measuring attrition are required.
