RESUMEN

BACKGROUND: Preeclampsia and eclampsia are among the leading direct causes of maternal death and morbidity worldwide. Up to 34% of maternal deaths in Tanzania are due to preeclampsia/ eclampsia. Magnesium sulfate is recommended for preventing and treating convulsions in women with Preeclampsia or eclampsia. However, evidence suggests limited knowledge of its dosage and proper toxicity assessment after administration among health care providers. AIM OF THE STUDY: This study explored nurse-midwives' perspectives on providing MgSO4 to patients with preeclampsia or eclampsia in Tanzania. MATERIALS AND METHODS: A descriptive exploratory qualitative study using in-depth interviews was conducted to understand nurse-midwives' perspectives on providing magnesium sulfate to patients with PE/E. Nineteen nurse-midwives were interviewed from three hospitals in the Dar es Salaam region. We used a semi-structured interview guide in Kiswahili language to collect data. All interviews were digitally recorded and transcribed verbatim. We analyzed data using inductive content analysis. RESULTS: This study revealed that nurse-midwives provide magnesium sulfate to save the lives of women and their unborn children. Nurse-midwives reasoned that confidence in their skill enhances provision of magnesium sulfate. However, they were concerned about its effect on the progress of labour. Ineffective use of magnesium sulfate emerged from inadequate training, an unsupportive work environment, and underutilization of the existing guidelines. CONCLUSION: Nurse-midwives have clear drive to provide magnesium sulfate to women with preeclampsia or eclampsia. However, inadequate training, underutilization of guidelines and unsupportive work environment lead to ineffective use of magnesium sulfate. Targeted practical training should be emphasized for nurse-midwives mastery of clinical competencies.

RESUMEN

BACKGROUND: The cancer burden in Africa is on the rise. A Cancer Training Course on screening, prevention, care, and community education is crucial for addressing a wide range of cancer health issues. When appropriately educated healthcare providers on cancer provide care, patient care improves, and healthcare costs decrease. However, in Tanzania, doctors and nurses receive little or no training in primary cancer care in their bachelor's program. AIM: This study assessed the need and acceptability of a cancer training course for nursing and medical doctor students at the Muhimbili University of Health and Allied Sciences (MUHAS) in Dar es Salaam, Tanzania. METHODS: This study was a cross-sectional parallel mixed method study during the 3-month follow-up within the larger study on sexual health training for health professionals. The study was a randomized controlled (RCT), single-blind, parallel trial of sexual health training versus a waitlist control among health students at MUHAS in Tanzania. Descriptive analysis was performed to analyze the participants' demographic information, need, and acceptability of the cancer training courseto determine the frequencies and percentages of their distribution between disciplines. In addition, inductive thematic analysis was performed for the qualitative data. The RCT study was registered at Clinical Trial.gov (NCT03923582; 01/05/2021). RESULTS: Data were collected from 408 students (272 medical doctors and 136 nursing students). The median age of the participants was 23 years. Most (86.0%) medical and 78.1% of nursing students reported receiving little to no cancer training. On the other hand, most (92.3%) medical and nursing (92.0%) students were interested in receiving cancer training. Furthermore, 94.1% of medical and 92.0% of nursing students needed a cancer training course in their undergraduate program. In addition, participants said a cancer training course would be important because it would help them improve the quality of cancer care and enhance the quality of life for patients by ensuring early diagnosis and treatment. CONCLUSION: A cancer training course is both highly needed and acceptable to medical and nursing students. Implementation of this cancer training course will improve students' knowledge and skills and eventually improve the quality of cancer care and patients' quality of life by ensuring early diagnosis and management.

RESUMEN

BACKGROUND: Low- and middle-income countries face a disproportionate impact of sexual health problems compared to high-income countries. To address this situation proper interpersonal communication skills are essential for clinician to gather necessary information during medical history-taking related to sexual health. This study aimed to evaluate the interrater reliability of ratings on sexual health-related interpersonal communication and medical history-taking between SPs and trained HCP faculty for health care professional students. METHODS: We conducted a cross-sectional comparative study to evaluate the interrater reliability of ratings for sexual health-related interpersonal communication and medical history-taking. The data were collected from medical and nursing students at Muhimbili University of Health and Allied Sciences, who interviewed 12 Standardized Patients (SPs) presenting with sexual health issues. The video-recorded interviews rated by SPs, were compared to the one rated by 5 trained Health Care Professional (HCP) faculty members. Inter-rater reliability was evaluated using percent agreement (PA) and kappa statistics (κ). RESULTS: A total of 412 students (mean age 24) were enrolled in the study to conduct interviews with two SPs presenting with sexual health concerns. For interpersonal communication (IC), the overall median agreement between raters was slight (κ2 0.0095; PA 48.9%) while the overall median agreement for medical sexual history-taking was deemed fair (κ2 0.139; PA 75.02%). CONCLUSION: The use of SPs for training and evaluating medical and nursing students in Tanzania is feasible only if they undergo proper training and have sufficient time for practice sessions, along with providing feedback to the students.

RESUMEN

PROBLEM: Although the practice of medicine is often emotionally challenging, medical curricula seldom systematically address the emotional development of medical students. To fill this gap, the authors developed and evaluated an innovative pedagogical activity based on music to nurture medical students' emotional development. The authors believe that the metaphoric nature of music offers an efficient venue for exploring emotion perception, expression, and regulation. APPROACH: The pedagogical activity Emotions in Medicine was carried out throughout 2020 and 2021 and consisted of 4 encounters to explore: (1) emotion perception, (2) emotion expression, (3) emotion regulation, and (4) the role of emotions in medical practice. During all encounters, the authors used music to evoke students' emotions and focused the discussions on the relevance of emotions for meaningful medical practice. Emotional intelligence before and after the workshop was tested using the Schutte Self-Report Emotional Intelligence Test (SSEIT), a validated psychometric scale. OUTCOMES: The workshop facilitated emotional connection among students and created a safe space to explore the role of emotions in medical practice. The mean total pretest SSEIT score was 110 (SD = 14.2); it increased to 116.8 (SD = 16.1) in the posttest ( P < .001). This increase was true across its 4 dimensions: (1) perception of emotions, (2) management of own emotions (3) management of others' emotions, and (4) use of emotions. NEXT STEPS: Music can be an active tool to explore the role of emotions in medical practice. It fosters students' capacity to identify and reflect on emotions while exploring their role in patient care. Further (qualitative) research is needed to explore the mechanisms by which music facilitates learning emotion perception, expression, and regulation.

RESUMEN

BACKGROUND: Female genital mutilation/cutting (FGM/C) is tied to one of the most conservative cultures in the Mediterranean and Sub-Saharan Africa. More than 200 million girls and women in 30 African, Asian and the middle Eastern countries have undergone FGM/C. However, healthcare professionals are not adequately trained to prevent and manage FGM/C-related complications including sexual health problems. This study aimed to assess the need and acceptability of a curriculum to train nursing and medical students in the sexual healthcare of clients with FGM/C in Tanzania. METHODS: We used a descriptive and cross sectional study design to collect and analyse information from 271 medical and 137 nursing students in Tanzania. A Qualtrics online survey was used to obtain quantitative data on training interest, previous training received, and the curriculum delivery method. Open-ended questions were used to explore their insights on significance to obtain the necessary competencies to treat and prevent FGM/C. Descriptive statistics were used to analyze quantitative data while qualitative data were analyzed using a thematic approach. RESULTS: Almost half of the participants reported they had little to no training in sexual healthcare for women with FGM/C (47%). In all, 82.4% reported the training to be acceptable. Following thematic analysis of open-ended questions, participants expressed a desire to improve their competencies to meet the current and future sexual and psychological health needs of women and girls who have undergone FGM/C. CONCLUSION: It is a necessary and acceptable to develop a curriculum to train healthcare students to diagnose, treat and prevent sexual health complications related to FGM/C. In our study, designing a culturally sensitive curriculum and its delivery method, that includes practical sessions with simulated patients, was considered the most beneficial and favorable.

RESUMEN

Little is known about the factors that may prevent healthcare professionals as key stakeholders from exploring sexual health issues in Tanzania. This study examined healthcare professionals' perspectives on the barriers to addressing sexual health concerns in practice. In June 2019, we conducted an exploratory qualitative study involving 18 focus group discussions among healthcare professionals (n = 60) and students (n = 61) in the health professions (midwifery, nursing, medicine) in Dar es Salaam, Tanzania. Study participants and design were purposively selected and stratified. We used a focus group discussion guide in Kiswahili. Data were transcribed in Kiswahili and translated into English. A thematic analysis approach was used for data analysis. Two themes were developed: (1) differences between health care professional and patient socio-demographic characteristics; (2) health care system and patients' backgrounds, such as communication barriers, lack of confidentiality and privacy within health facilities, type of clinical presentation and complaint, patient behaviours, and their clinical background. Several key barriers prevented sexual health communication between healthcare professionals and patients, affecting the quality of sexual health service delivery. Additional sexual health clinical training is warranted for health professions students and professionals to optimise sexual health care delivery in a culturally conservative country like Tanzania.

RESUMEN

INTRODUCTION: In Low- and Middle-Income Countries (LMICs), maternal and infant mortality remains a significant problem. Inadequate healthcare provider competencies, including those of midwives, are cited as one of the major contributors to the high maternal and newborn mortality rates. Thus, enhancing the skills of midwives is a prerequisite for enhancing positive maternal and newborn health outcomes. This study describes the lessons learned from a Midwifery Emergencies Skills Training (MEST) project implemented in Tanzania between 2013 and 2018. METHODS: An exploratory qualitative study was used to purposefully recruit and interview twelve health facility in-charges and eighteen midwives from twelve selected health facilities in six districts of Tanzania mainland to discover their perceptions about the midwifery practice after MEST training. The data were transcribed verbatim and analysed with qualitative content analysis. RESULTS: Four categories were generated from the analysis (i) enhanced knowledge and skills in the provision of midwifery care and management of obstetric emergencies, (ii) improved midwives' communication skills, (iii) increased trust and support between midwives and community and (iv) transformed attitudes of midwives toward continued professional development (CPD). CONCLUSION: MEST enhanced the knowledge and skills of midwives in the management of obstetric emergencies and referral protocol practice. However, notable gaps remain in the capacity of midwives to provide human rights-based respectful maternity care. Continued professional development for nurses and midwives through training, mentorship and supervision programs is recommended for improving maternal and newborn health.

RESUMEN

INTRODUCTION: Sexual and reproductive health problems are one of the top five risk factors for disability in the developing world. The rates of sexual health problems in most African countries are overwhelming, which is why HIV and other STIs are still such a challenge in sub-Saharan Africa. Talking about sex in most African countries is a taboo, leading to common myths and misconceptions that ultimately impact community sexual health. METHODS: In this study, we conducted 11 key stakeholder individual interviews with community, religious, political, and health leaders (sexual health stakeholders) in Tanzania. Qualitative content analysis was used to analyze all the materials. RESULTS: Two main categories merged from the analysis. The first category, "Ambiguities about sexual health" focused on societal and political misconceptions and identified ten myths or misconceptions common in Tanzania. Stakeholders highlighted the confusion that happens when different information about sexual health is presented from two different sources (e.g., community leaders/peers and political leaders), which leaves the community and community leaders unsure which one is reliable. The second category, "Practical dilemmas in serving clients", addressed a range of professional and religious dilemmas in addressing sexual health concerns. This included the inability of religious leaders and health care providers to provide appropriate sexual health care because of internal or external influences. CONCLUSION: Myths and misconceptions surrounding sexual health can prevent communities from adequately addressing sexual health concerns, and make it more difficult for healthcare providers to comfortably provide sexual health care to patients and communities. Stakeholders affirmed a need to develop a sexual health curriculum for medical, nursing and midwifery students because of the lack of education in this area. Such a curriculum needs to address nine common myths which were identified through the interviews.

RESUMEN

BACKGROUND: Minimal residual disease (MRD) is one of the most valuable independent prognostic factors in acute lymphoblastic leukemia (ALL). Bone marrow (BM) aspiration, however, is an invasive process. Previous studies have shown that microRNAs (miR) and extracellular vesicle (EV)-related miRs show different expression profiles at the presence of malignant cells compared to healthy controls. In our previous project, we have reported that two miRs previously described to be overexpressed in blasts were significantly decreased over the first week of the therapy of patients with ALL in the platelet free plasma fraction (PFP) of peripheral blood samples (PB). The aim of the current study was to assess the relation between day 15 flow cytometry (FC) MRD and expression of miR-128-3p and miR-222-3p miRs in exosome-enriched fraction (EEF) of PFP to evaluate whether their expression in EEF correlates with day 15 FC MRD more precisely. METHODS: PB was collected from 13 patients diagnosed with pediatric pre-B ALL at 4 time points. Expression of miR-128-3p and miR-222-3p was measured by qPCR in PFP and EEF. RESULTS: Positive correlation was found between changes of miR-128-3p expression in EEF or PFP by day 8 of chemotherapy and day 15 FC MRD (rEEF = 0.99, pEEF = 1.13E-9 and rPFP = 0.99, pPFP = 4.75E-9, respectively). Furthermore, the decrease of miR-128-3p in EEF by day 15 of treatment also showed a positive correlation with day 15 FC MRD (rEEF = 0.96; pEEF = 4.89E-5). CONCLUSION: Our results show that circulating miRs are potential biomarkers of ALL MRD, asmiR-128-3p level both in PFP and EEF predicts day 15 FC MRD. In addition, the assessment of the EEF gave a more promising result.

RESUMEN

Big defensins are two-domain antimicrobial peptides (AMPs) that have highly diversified in mollusks. Cg-BigDefs are expressed by immune cells in the oyster Crassostrea gigas, and their expression is dampened during the Pacific Oyster Mortality Syndrome (POMS), which evolves toward fatal bacteremia. We evaluated whether Cg-BigDefs contribute to the control of oyster-associated microbial communities. Two Cg-BigDefs that are representative of molecular diversity within the peptide family, namely Cg-BigDef1 and Cg-BigDef5, were characterized by gene cloning and synthesized by solid-phase peptide synthesis and native chemical ligation. Synthetic peptides were tested for antibacterial activity against a collection of culturable bacteria belonging to the oyster microbiota, characterized by 16S sequencing and MALDI Biotyping. We first tested the potential of Cg-BigDefs to control the oyster microbiota by injecting synthetic Cg-BigDef1 into oyster tissues and analyzing microbiota dynamics over 24 h by 16S metabarcoding. Cg-BigDef1 induced a significant shift in oyster microbiota ß-diversity after 6 h and 24 h, prompting us to investigate antimicrobial activities in vitro against members of the oyster microbiota. Both Cg-BigDef1 and Cg-BigDef5 were active at a high salt concentration (400 mM NaCl) and showed broad spectra of activity against bacteria associated with C. gigas pathologies. Antimicrobial specificity was observed for both molecules at an intra- and inter-genera level. Remarkably, antimicrobial spectra of Cg-BigDef1 and Cg-BigDef5 were complementary, and peptides acted synergistically. Overall, we found that primary sequence diversification of Cg-BigDefs has generated specificity and synergy and extended the spectrum of activity of this peptide family.

RESUMEN

BACKGROUND: Fear of childbirth is common both before and after childbirth, often leading to complications in mother and new-born. The Wijma Delivery Expectancy/Experience Questionnaires (W-DEQ) are commonly used to measure fear of childbirth among women before (version A) and after childbirth (version B). The tools are not yet validated in the Tanzanian context. This study aimed to validate the reliability, validity, and factorial structure of their Kiswahili translations. METHODS: A longitudinal study was conducted in six public health facilities in the Pwani region, Tanzania. In all, 694 pregnant and 625 postnatal women were concurrently selected and responded to W-DEQ-A and W-DEQ-B. Validation involved: translating the English questionnaires into Kiswahili; expert rating of the relevancy of the Kiswahili versions' items; computing content validity ratio; piloting the tools; data collection; statistical analysis with reliability evaluated using Cronbach's alpha and the intraclass correlation coefficient. Tool validity was assessed using factor analysis, convergent and discriminant validity. Exploratory factor analysis and confirmatory factor analysis were conducted on data collected using W-DEQ-A and W-DEQ-B, respectively. RESULTS: Exploratory factor analysis revealed seven factors contributing to 50% of the total variation. Four items did not load to any factor and were deleted. The factors identified were: fear; lack of self-efficacy; lack of positive anticipation; isolation; concerns for the baby; negative emotions; lack of positive behaviour. The factors correlated differently with each other and with the total scores. Both Kiswahili versions with 33 items had good internal consistency, with Cronbach's alphas of .83 and .85, respectively. The concerns for the baby factor showed both convergent and discriminant validity. The other six factors showed some problems with convergent validity. The final model from the confirmatory factor analysis yielded 29 items with good psychometric properties (χ2/df = 2.26, p = < .001, RMSEA = .045, CFI = .90 and TLI = .81). CONCLUSIONS: The Kiswahili W-DEQ-A-Revised and W-DEQ-B-Revised are reliable tools and measure fear of childbirth with a multifactorial structure, encompassing seven factors with 29 items. They are recommended for measuring fear of childbirth among pregnant and postnatal Tanzanian women. Further studies are needed to address the inconsistent convergent validity in the revised versions and assess the psychometric properties of W-DEQ-A among pregnant women across gestational ages.

RESUMEN

Aphids (Hemiptera: Aphidoidea) are among the most detrimental insects for agricultural plants, and their management is a great challenge in agronomical research. A new class of proteins, called Bacteriocyte-specific Cysteine-Rich (BCR) peptides, provides an alternative to chemical insecticides for pest control. BCRs were initially identified in the pea aphid Acyrthosiphon pisum. They are small disulfide bond-rich proteins expressed exclusively in aphid bacteriocytes, the insect cells that host intracellular symbiotic bacteria. Here, we show that one of the A. pisum BCRs, BCR4, displays prominent insecticidal activity against the pea aphid, impairing insect survival and nymphal growth, providing evidence for its potential use as a new biopesticide. Our comparative genomics and phylogenetic analyses indicate that BCRs are restricted to the aphid lineage. The 3D structure of BCR4 reveals that this peptide belongs to an as-yet-unknown structural class of peptides and defines a new superfamily of defensins.

RESUMEN

Introduction: Sexual health care services must be standard and unbiased, guided by a structured health care system. There is a scarcity of data on how sexual health care is delivered in Tanzania. Methods: To address this gap, in July 2019 we interviewed eleven key informants: cultural and public health experts, and political, religious, and community leaders, selected from different organizations in Dar es Salaam, Tanzania. Participants were asked for their opinions about clinical practices of health care professionals when providing care to patients, with an emphasis on sexual health. Results: Participants' responses were classified into three subcategories: strengths, barriers, and gaps in sexual health care. Availability of services, service delivery to adults, and code of conduct were among the strengths observed in clinical care services. Barriers included the health care provider's attitudes, moral values, and inadequacy in health policies and treatment guidelines. Vulnerable populations including youth were frequently reported to face most challenges when seeking sexual health care services. In terms of gaps, informants emphasized gender equity in sexual health services provision within care settings. Conclusion and Implication: Data indicate that lack of training in sexual health and guidelines for dealing with sexual issues are a barrier to comprehensive health care. These findings can inform the main areas for curriculum developers to focus on, when developing an Afro-centric sexual health curriculum suitable for students in health care professional courses. Moreover, these findings can be useful when developing treatment guidelines and policies that are beneficial to the sexual health wellbeing of individuals.

RESUMEN

BACKGROUND:  Tanzania is a country experiencing multiple sexual health challenges, but providers receive no formal training in sexual health. AIM:  This study aimed to assess (1) what sexual health challenges are commonly seen in clinics in Tanzania, (2) which are raised by patients, (3) which are not addressed and (4) which topics to prioritise for a sexual health curriculum. SETTING:  Healthcare settings in Tanzania. METHODS:  Participants were 60 experienced and 61 student doctors, nurses and midwives working in Dar es Salaam. The authors conducted 18 focus groups stratified by profession (midwifery, nursing or medicine) and experience (practitioners vs. students). RESULTS:  Providers identified six common sexual health concerns: (1) Human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) and sexually transmissible infection (STI) (especially syphilis and gonorrhoea), (2) sexual violence (including intimate partner violence and female genital mutilation), (3) early and unwanted pregnancy (including early sexual debut and complications from abortion), (4) sexual dysfunctions, (5) key population concerns (e.g. lesbian, gay, bisexual, transgender (LGBT); sex work) and (6) non-procreative sexual behaviour (including pornography and masturbation in males and oral and anal sex practices in heterosexual couples). Across professions, few differences were observed. Homosexuality, sex work, masturbation and pornography were identified as taboo topics rarely discussed. Most participants (81%) wanted one comprehensive sexual health curriculum delivered across disciplines. CONCLUSION:  A sexual health curriculum for health students in Tanzania needs to address the most common sexual health concerns of patients. In addition to teaching sexual science and clinical care, skills training in how to address taboo topics is recommended. Students endorsed almost all sexual health topics, which suggests that a comprehensive curriculum is appropriate.

RESUMEN

Central nervous system (CNS) involvement is a leading cause of therapy-refractory pediatric acute lymphoblastic leukemia (pALL), which is aggravated by underdiagnosing CNS disease with the currently used cell-based approach of cerebrospinal fluid (CSF) diagnostics. Our study focused on developing novel subcellular CNS leukemia indicators in the CSF and the bone marrow (BM) of patients with pALL. Serial liquid biopsy samples (n = 65) were analyzed by Elisas to measure the level of essential proteins associated with blast cell CNS trafficking, vascular endothelial growth factor A (VEGF-A) and integrin alpha 6 (ITGA6). In CSF samples from early induction chemotherapy, VEGF-A concentration were uniformly elevated in the CNS-positive group compared to those patients without unambiguous meningeal infiltration (9 vs Nine patients, Δc = 17.2 pg/ml, p = 0.016). Expression of miR-181a, a VEGFA-regulating microRNA which showed increased level in CNS leukemia in our previous experiments, was then paralleled with VEGF-A concentration. A slight correlation between the levels of miR-181a and VEGF-A indicators in CSF and BM samples was revealed (n = 46, Pearson's r = 0.36, p = 0.015). After validating in international cohorts, the joint quantification of miR-181a and VEGF-A might provide a novel tool to precisely diagnose CNS involvement and adjust CNS-directed therapy in pALL.

RESUMEN

(1) Antimicrobial peptides (AMPs) are a promising alternative to conventional antibiotics. Among AMPs, the disulfide-rich ß-defensin AvBD103b, whose antibacterial activities are not inhibited by salts contrary to most other ß-defensins, is particularly appealing. Information about the mechanisms of action is mandatory for the development and approval of new drugs. However, data for non-membrane-disruptive AMPs such as ß-defensins are scarce, thus they still remain poorly understood. (2) We used single-cell fluorescence imaging to monitor the effects of a ß-defensin (namely AvBD103b) in real time, on living E. coli, and at the physiological concentration of salts. (3) We obtained key parameters to dissect the mechanism of action. The cascade of events, inferred from our precise timing of membrane permeabilization effects, associated with the timing of bacterial growth arrest, differs significantly from the other antimicrobial compounds that we previously studied in the same physiological conditions. Moreover, the AvBD103b mechanism does not involve significant stereo-selective interaction with any chiral partner, at any step of the process. (4) The results are consistent with the suggestion that after penetrating the outer membrane and the cytoplasmic membrane, AvBD103b interacts non-specifically with a variety of polyanionic targets, leading indirectly to cell death.

RESUMEN

BACKGROUND: Rates of unplanned adolescent pregnancy and unsafe induced abortions are very high in Sub-Saharan African countries including Tanzania. Despite their availability and accessibility, modern family planning methods are reported to be critically underutilized by adolescents. This study is part of a broader study that aims to develop a curriculum that will be used in training health professionals by investigating the sexual health training needs of health providers and students in Tanzania. AIM: This study describes the perceptions of health professionals and students on the provision of contraceptives to adolescents. METHODS: Qualitative formative assessment type of research was conducted using 18 focus groups stratified among health professionals and students (midwives, nurses, and medical doctors). Study participants were presented with the theoretical scenario of a 14-year-old girl who sought contraceptive services at a family planning clinic. This theoretical scenario was used to determine how health professionals and students would handle the case. Thematic analysis guided the examination and determination of data results. RESULTS: Three main themes emerged from the data, including (1) knowledge about the provision of contraceptives to adolescents, (2) perception of the adolescents' right to contraceptive use, and (3) barriers to the provision of contraceptives to adolescents. Participants stated that having a baseline knowledge of contraceptive services for adolescents and their rights to contraceptives would trigger their decision on offering the contraceptive. On the other hand, being unaware of the reproductive health rights for adolescents, judgmental behavior of providers, as well as religious and cultural dynamics were all found to be major barriers for providers to offer contraceptive services to the 14-year-old adolescent girl in the theoretical scenario. CONCLUSION: These findings support the need for comprehensive sexual health education in Tanzanian health professional training programs.

In Tanzania, adolescent pregnancies are culturally unwanted, abortion remains illegal and yet the utilization of family planning services among adolescents is still low. The community myths and misconceptions about the side effects of contraceptives, healthcare providers' attitudes, and barriers within the healthcare system hinder adolescents' utilization of family planning services. The effective use of family planning methods will prevent the use of unsafe induced abortions and hence reduce morbidity and mortality among young women. This will be possible only if healthcare providers are equipped with the knowledge and skills to address these sexual and reproductive health challenges among adolescents in Tanzania. Therefore, in this study, we decided to explore the perceptions of health professionals and students on the provision of contraception to adolescents. We conducted 18 focus groups stratified among health professionals and students (midwives, nurses, medical doctors). Participants were supplied with a theoretical scenario wherein a 14-year-old girl presented to a family planning clinic seeking contraceptive services to determine how health professionals and students would handle the case. We found that the decision of providers with regards to offering contraception is highly dependent on having a baseline knowledge of the rights and contraceptive services available to adolescents. Some barriers identified as reasons for providers not to offer contraceptive services include a lack of awareness of the reproductive health rights for adolescents, judgmental behavior (implicit and explicit biases among providers), as well as religious and cultural dynamics. Participants also acknowledged that the presence of guidelines and proper training among providers might avoid the infringement of adolescents' rights to sexual and reproductive health services. In conclusion, these findings support the need for comprehensive sexual health education in Tanzanian health professional training programs.

RESUMEN

Malignant melanoma is one of the most highly ranked cancers in terms of years of life lost. Hereditary melanoma with its increased familial susceptibility is thought to affect up to 12% of all melanoma patients. In the past, only a few high-penetrance genes associated with familial melanoma, such as CDKN2A and CDK4, have been clinically tested. However, findings now indicate that melanoma is a cancer most likely to develop not only due to high-penetrance variants but also due to polygenic inheritance patterns, leaving no clear division between the hereditary and sporadic development of malignant melanoma. Various pathogenic low-penetrance variants were recently discovered through genome-wide association studies, and are now translated into polygenic risk scores. These can show superior sensitivity rates for the prediction of melanoma susceptibility and related mixed cancer syndromes than risk scores based on phenotypic traits of the patients, with odds ratios of up to 5.7 for patients in risk groups. In addition to describing genetic findings, we also review the first results of epigenetic research showing constitutional methylation changes that alter the susceptibility to cutaneous melanoma and its risk factors.

RESUMEN

BACKGROUND: Child sexual abuse (CSA) is a significant public health problem affecting one billion children aged 2 to 17 globally. The prevalence of CSA in Tanzania is one of the highest; however, how health care providers manage CSA cases has not been studied. OBJECTIVES: This study investigated how medical, nursing, and midwifery professionals in Tanzania handle cases of CSA and identified the factors that facilitate or impede the provision of quality care to CSA victims. METHODS: Participants were 60 experienced healthcare professionals and 61 health students working in Dar es Salaam, Tanzania. We conducted 18 focus groups stratified by profession (midwifery, nursing, or medicine) and experience (practitioners versus students). RESULTS: Three main themes emerged. First, child abuse management involved using a multi-disciplinary approach, including proper history taking, physical assessment, treatment, and referral. Second, factors that enhanced disclosure of CSA included building rapport, privacy, and confidentiality. Third, factors that impeded care included fear of harm to the child if the abuse was reported, abuse reporting being perceived as a "waste of time" for providers, loss of evidence from the victim, family resistance, poverty, corruption and cultural dynamics. CONCLUSIONS: Midwives, nurses and doctors were all experienced in and reported similar challenges in addressing CSA. At a structural level, the ratio of providers to patients in health facilities inhibits quality care. These findings have implications for strengthening CSA policy/guidelines and clinical practice in Tanzania. Mandated CSA training is necessary for midwifery, nursing, and medical students as well as in continuing education courses for more experienced providers.

RESUMEN

INTRODUCTION: Africa has high rates of interpersonal violence and rape, although little is known about how these cases are handled in the clinical setting. METHODS: We enrolled 121 health care professionals and students in Tanzania from the fields of midwifery, nursing and medicine, and conducted 18 focus group discussions stratified by both professional and clinical experience. Two clinical scenarios were presented across all groups and participants were asked to give their opinions on how the hospital they worked in would manage the cases. Case 1 focused on how to address a case of an injured woman beaten by her husband (and whether the perpetrator would be reported to the police). Case 2 focused on how to handle a rape victim who is brought to the hospital by the police. RESULTS: Participants considered both cases as emergencies. There was a similarity in the clinical care procedures across both scenarios. This included building rapport with the patient, prioritization of the medical care, history taking, and referring to other specialties for follow-up. Participants differed in how they would handle the legal aspects of both cases, including whether and how to best follow mandated reporting policies. Providers wondered if they should report the husband in case study 1, the criteria for reporting, and where to report. Providers displayed a lack of knowledge about resources needed for sexual violence victim and the availability of resources. CONCLUSION: These findings indicate that cases of intimate partner violence and rape are likely to be under-reported within hospitals and clinics in Tanzania. Health care providers lack training in their required obligations and procedures that need to be followed to ensure victim's safety. The findings confirm that there is a need for health care students in Tanzania (and possibly Africa) to receive comprehensive training in how to handle such cases.
