    BACKGROUND: Tubal sterilization is the method of family planning most commonly used. The existence of the post-tubal-ligation syndrome of menstrual abnormalities has been the subject of debate for decades. METHODS: In a cross-sectional study, 112 women with the history of Pomeroy type of tubal ligation achieved by minilaparatomy as the case group and 288 women with no previous tubal ligation as the control group were assessed for menstrual abnormalities. RESULTS: Menstrual abnormalities were not significantly different between the case and control groups (p = 0.824). The abnormal uterine bleeding frequency differences in two different age groups (30–39 and 40–45 years old) were statistically significant (p = 0.0176). CONCLUSION: Tubal sterilization does not cause menstrual irregularities

    BACKGROUND : Research on various determinants of health is key in providing evidence for policy development, thereby leading to successful interventions. Utilization of research is an intricate process requiring an understanding of contextual factors. The study was conducted to assess enhancing factors and barriers of research utilization for malaria policy development in Malawi. METHODS : Qualitative research approach was used through in-depth interviews with 39 key informants that included malaria researchers, policy makers, programme managers, and key stakeholders. Purposive sampling and snowballing techniques were used in identifying key informants. Interview transcripts were entered in QSR Nvivo 11 software for coding and analysis. RESULTS : Respondents identified global efforts as key in advancing knowledge translation, while local political will has been conducive for research utilization. Other factors were availability of research, availability of diverse local researchers and stakeholders supporting knowledge translation. While barriers included: lack of platforms for researcher-public engagement, politics, researchers’ lack of communication skills, lack of research collaborations, funder driven research, unknown World Health Organization policy position, and the lack of a malaria research repository. CONCLUSION : Overall, the study identified facilitating factors to malaria research utilization for policy development in Malawi. These factors need to be systematically coordinated to address the identified barriers and improve on malaria research utilization in policy development. Malaria research can be key in the implementation of evidence-based interventions to reduce the malaria burden and assist in the paradigm shift from malaria control to elimination in Malawi.University of Pretoria Institute for Sustainable Malaria Control (UP ISMC)http://www.malariajournal.comam2016School of Health Systems and Public Health (SHSPH

    BACKGROUND. Empirical data showing the clear benefits of exclusive breastfeeding (EBF) for HIV prevention are needed to encourage implementation of lactation support programs for HIV-infected women in low resource settings among whom replacement feeding is unsafe. We conducted a prospective, observational study in Lusaka, Zambia, to test the hypothesis that EBF is associated with a lower risk of postnatal HIV transmission than non-EBF. METHODS AND RESULTS. As part of a randomized trial of early weaning, 958 HIV-infected women and their infants were recruited and all were encouraged to breastfeed exclusively to 4 months. Single-dose nevirapine was provided to prevent transmission. Regular samples were collected from infants to 24 months of age and tested by PCR. Detailed measurements of actual feeding behaviors were collected to examine, in an observational analysis, associations between feeding practices and postnatal HIV transmission. Uptake of EBF was high with 84% of women reporting only EBF cumulatively to 4 months. Post-natal HIV transmission before 4 months was significantly lower (p = 0.004) among EBF (0.040 95% CI: 0.024–0.055) than non-EBF infants (0.102 95% CI: 0.047–0.157); time-dependent Relative Hazard (RH) of transmission due to non-EBF = 3.48 (95% CI: 1.71–7.08). There were no significant differences in the severity of disease between EBF and non-EBF mothers and the association remained significant (RH = 2.68 95% CI: 1.28–5.62) after adjusting for maternal CD4 count, plasma viral load, syphilis screening results and low birth weight. CONCLUSIONS. Non-EBF more than doubles the risk of early postnatal HIV transmission. Programs to support EBF should be expanded universally in low resource settings. EBF is an affordable, feasible, acceptable, safe and sustainable practice that also reduces HIV transmission providing HIV-infected women with a means to protect their children's lives.

    To evaluate the support from the available guidance on reporting of health equity in research for our candidate items and to identify additional items for the Strengthening Reporting of Observational studies in Epidemiology-Equity extension. We conducted a scoping review by searching Embase, MEDLINE, CINAHL, Cochrane Methodology Register, LILACS, and Caribbean Center on Health Sciences Information up to January 2022. We also searched reference lists and gray literature for additional resources. We included guidance and assessments (hereafter termed "resources") related to conduct and/or reporting for any type of health research with or about people experiencing health inequity. We included 34 resources, which supported one or more candidate items or contributed to new items about health equity reporting in observational research. Each candidate item was supported by a median of six (range: 1-15) resources. In addition, 12 resources suggested 13 new items, such as "report the background of investigators". Existing resources for reporting health equity in observational studies aligned with our interim checklist of candidate items. We also identified additional items that will be considered in the development of a consensus-based and evidence-based guideline for reporting health equity in observational studies

    Institutional capacity for health systems research in East and Central African schools of public health: knowledge translation and effective communication

    Get PDF
    BACKGROUND: Local health systems research (HSR) provides policymakers and practitioners with contextual, evidence-based solutions to health problems. However, producers and users of HSR rarely understand the complexities of the context within which each operates, leading to the “know–do” gap. Universities are well placed to conduct knowledge translation (KT) integrating research production with uptake. The HEALTH Alliance Africa Hub, a consortium of seven schools of public health (SPHs) in East and Central Africa, was formed to build capacity in HSR. This paper presents information on the capacity of the various SPHs to conduct KT activities. METHODS: In 2011, each member of the Africa Hub undertook an institutional HSR capacity assessment using a context-adapted and modified self-assessment tool. KT capacity was measured by several indicators including the presence of a KT strategy, an organizational structure to support KT activities, KT skills, and institutional links with stakeholders and media. Respondents rated their opinions on the various indicators using a 5-point Likert scale. Averages across all respondents for each school were calculated. Thereafter, each school held a results validation workshop. RESULTS: A total of 123 respondents from all seven SPHs participated. Only one school had a clear KT strategy; more commonly, research was disseminated at scientific conferences and workshops. While most respondents perceived their SPH as having strong institutional ties with organizations interested in HSR as well as strong institutional leadership, the organizational structures required to support KT activities were absent. Furthermore, individual researchers indicated that they had little time or skills to conduct KT. Additionally, institutional and individual links with policymakers and media were reported as weak. CONCLUSIONS: Few SPHs in Africa have a clear KT strategy. Strengthening the weak KT capacity of the SPHs requires working with institutional leadership to develop KT strategies designed to guide organizational structure and development of networks with both the media and policymakers to improve research uptake.DFI

    Controversy and Consensus on Indications for Sperm DNA Fragmentation Testing in Male Infertility: A Global Survey, Current Guidelines, and Expert Recommendations

    Get PDF
    Purpose: Sperm DNA fragmentation (SDF) testing was recently added to the sixth edition of the World Health Organization laboratory manual for the examination and processing of human semen. Many conditions and risk factors have been associated with elevated SDF; therefore, it is important to identify the population of infertile men who might benefit from this test. The purpose of this study was to investigate global practices related to indications for SDF testing, compare the relevant professional society guideline recommendations, and provide expert recommendations. Materials and Methods: Clinicians managing male infertility were invited to take part in a global online survey on SDF clinical practices. This was conducted following the CHERRIES checklist criteria. The responses were compared to professional society guideline recommendations related to SDF and the appropriate available evidence. Expert recommendations on indications for SDF testing were then formulated, and the Delphi method was used to reach consensus. Results: The survey was completed by 436 experts from 55 countries. Almost 75% of respondents test for SDF in all or some men with unexplained or idiopathic infertility, 39% order it routinely in the work-up of recurrent pregnancy loss (RPL), and 62.2% investigate SDF in smokers. While 47% of reproductive urologists test SDF to support the decision for varicocele repair surgery when conventional semen parameters are normal, significantly fewer general urologists (23%; p=0.008) do the same. Nearly 70% would assess SDF before assisted reproductive technologies (ART), either always or for certain conditions. Recurrent ART failure is a common indication for SDF testing. Very few society recommendations were found regarding SDF testing. Conclusions: This article presents the largest global survey on the indications for SDF testing in infertile men, and demonstrates diverse practices. Furthermore, it highlights the paucity of professional society guideline recommendations. Expert recommendations are proposed to help guide clinicians

    Controversy and consensus on the management of elevated sperm DNA fragmentation in male infertility: A global survey, current guidelines, and expert recommendations

    Purpose Sperm DNA fragmentation (SDF) has been associated with male infertility and poor outcomes of assisted reproductive technology (ART). The purpose of this study was to investigate global practices related to the management of elevated SDF in infertile men, summarize the relevant professional society recommendations, and provide expert recommendations for managing this condition. Materials and Methods An online global survey on clinical practices related to SDF was disseminated to reproductive clinicians, according to the CHERRIES checklist criteria. Management protocols for various conditions associated with SDF were captured and compared to the relevant recommendations in professional society guidelines and the appropriate available evidence. Expert recommendations and consensus on the management of infertile men with elevated SDF were then formulated and adapted using the Delphi method. Results A total of 436 experts from 55 different countries submitted responses. As an initial approach, 79.1% of reproductive experts recommend lifestyle modifications for infertile men with elevated SDF, and 76.9% prescribe empiric antioxidants. Regarding antioxidant duration, 39.3% recommend 4–6 months and 38.1% recommend 3 months. For men with unexplained or idiopathic infertility, and couples experiencing recurrent miscarriages associated with elevated SDF, most respondents refer to ART 6 months after failure of conservative and empiric medical management. Infertile men with clinical varicocele, normal conventional semen parameters, and elevated SDF are offered varicocele repair immediately after diagnosis by 31.4%, and after failure of antioxidants and conservative measures by 40.9%. Sperm selection techniques and testicular sperm extraction are also management options for couples undergoing ART. For most questions, heterogenous practices were demonstrated. Conclusions This paper presents the results of a large global survey on the management of infertile men with elevated SDF and reveals a lack of consensus among clinicians. Furthermore, it demonstrates the scarcity of professional society guidelines in this regard and attempts to highlight the relevant evidence. Expert recommendations are proposed to help guide clinicians

    Is single-dose NVP relevant in the era of more efficacious PMTCT regimens? Lessons from Zambia

    No full text
    For almost a decade, single-dose nevirapine (sdNVP) has been proven to be a safe and effective drug for the prevention of mother-to-child transmission (PMTCT) of HIV. With the advent of the use of more efficacious combination therapy strategy in reducing mother-to-child transmission, sdNVP has been relegated as a lower tier intervention. Availability of infrastructural capacity coupled with the practical reality that very few women attend an antenatal clinic more than once makes universal implementation of combination therapy a challenge. This retrospective review examined PMTCT programmatic indicators following the introduction of sdNVP at first contact in selected sites. Data from 79 PMTCT sites was reviewed from April 2006 to March 2007 (when sdNVP was offered only after 32 weeks) and compared to the period of April 2007–March 2008. In the pre-intervention period (April 2006–March 2007), the monthly average of pregnant women who received sdNVP per site was 5.02. Post-intervention (April 2007–March 2008), the monthly average increased by 59% to 7.97 (p-value<0.05). In pre-intervention period when sdNVP was dispensed at 32 weeks, the average proportion of pregnant women who received antiretroviral prophylaxis was 59%. This increased to 82% after the intervention. Current systems for dispensing sdNVP may be used as a foundation for implementation of more efficacious PMTCT regimens. The sdNVP administered at first contact should be a safety net for women who are unable to receive more efficacious regimen

    Infant feeding options, other nonchemoprophylactic factors, and mother-to-child transmission of HIV in Zambia

    No full text
    BACKGROUND: The role of antiretroviral drugs in the prevention of mother-to-child transmission (PMTCT) of HIV is well known. The objective of this study is to explore how nonchemoprophylactic factors, including infant feeding practices, mother's HIV status disclosure, mode and place of delivery, infant gender, and maternal age, are related to MTCT.METHODS: The study analyzed program data of DNA polymerase chain reaction (PCR) results from dried blood spot samples and selected client information from perinatally exposed infants aged 0 to 12 months.RESULTS: A total of 8237 samples were analyzed. In all, 84% of the mothers ever breast-fed their children. In instances where both mother and baby received intervention, the transmission rates of HIV were higher among those who are still breast-feeding after 6 to 12 months. Disclosure, location, and mode of delivery did not have an effect on the transmission rates of HIV when both mother and baby received prophylaxis.CONCLUSION: Nonchemoprophylaxis factors, especially breast-feeding, play a key role in perinatal transmission of HIV

    Ensuring that pregnant women are delivering in a health facility and are attended to by skilled birth attendants is critical to reducing maternal and infant morbidity and mortality. This study sought to determine the associations between male involvement in antenatal care (ANC) services and pregnant women delivering at health facilities and being attended to by skilled birth attendants as well as attending postnatal care. This was a retrospective cohort study using secondary analysis of program data. We reviewed health records of all pregnant women who attended antenatal services irrespective of HIV status between March and December 2012 in 10 health facilities in three provinces of Zambia. An extraction questionnaire was used to collect socio-demographic and clinical information from registers used in services for maternal neonatal child health as well as delivery. Using logistic regression, we calculated the odds ratios (OR) and 95% confidence intervals (CI) of the association between (1) male involvement and delivery at a health facility by a skilled birth attendant and (2) male involvement and women’s attendance at postnatal services. We found that more women who had been accompanied by their male partner during ANC delivered at a health facility than those who had not been accompanied (88/220=40% vs. 543/1787=30.4%, respectively; OR 1.53, 95% CI: 1.15-2.04). Also, we noted that a greater proportion of the women who returned for postnatal visits had been accompanied by their partner at ANC visits, compared to those women who came to ANC without their partner (106/220=48.2% vs. 661/1787=37.0%, respectively; OR 1.58, 95% CI: 1.20-2.10). Male involvement seems to be a key factor in women's health-seeking behaviours and could have a positive impact on maternal and infant morbidity and mortality. Keywords: antenatal care, HIV, males, facility delivery, postnatal care, Zambia.RĂ©sumĂ©S’assurer que les femmes enceintes accouchent dans un Ă©tablissement de santĂ© et qu’elles sont prises en charge par des accoucheuses qualifiĂ©es est essentiel pour rĂ©duire la morbiditĂ© et la mortalitĂ© maternelle et infantile. Cette Ă©tude visait Ă  dĂ©terminer les associations entre la participation des hommes aux services de soins prĂ©natals (SPrN) et des femmes enceintes qui accouchent dans des Ă©tablissements de santĂ© et d'ĂȘtre assistĂ©es par des accoucheuses qualifiĂ©es ainsi que la participation dans des soins postnatals (SPN). Il s’agissait d’une Ă©tude de cohorte rĂ©trospective effectuĂ© Ă  l’aide d’une analyse secondaire des donnĂ©es du programme. Nous avons examinĂ© les dossiers de santĂ© de toutes les femmes enceintes qui ont assistĂ© Ă  des services de soins prĂ©natals indĂ©pendamment de leur statut du VIH entre mars et dĂ©cembre 2012 dans 10 Ă©tablissements de santĂ© dans trois provinces de la Zambie. Un questionnaire d'extraction a Ă©tĂ© utilisĂ© pour recueillir des informations socio-dĂ©mographiques et cliniques Ă  partir des registres utilisĂ©s dans les services de santĂ© maternelle de l'enfant nouveau-nĂ© ainsi que l’accouchement. A l’aide de la rĂ©gression logistique, nous avons calculĂ© les odds ratios (OR) et 95% d’intervalles de confiance (IC) de l'association entre (1) la participation des hommes et de l’accouchement dans un Ă©tablissement de santĂ© par une accoucheuse qualifiĂ©e et (2) la participation des hommes et la prĂ©sence des femmes aux services postnatals. Nous avons constatĂ© que plus de femmes qui avaient Ă©tĂ© accompagnĂ©es de leurs partenaires masculins pendant SPrN ont accouchĂ© dans un Ă©tablissement de santĂ© que celles qui n’avaient pas Ă©tĂ© accompagnĂ©es (88/220 = 40% contre 543/1787 = 30,4%, respectivement; OR 1,53, 95% CI: 01/15 Ă  02/04). En outre, nous avons constatĂ© qu'une plus grande proportion des femmes qui sont revenues pour des visites postnatales avaient Ă©tĂ© accompagnĂ©es par leurs partenaires lors des visites prĂ©natales, par rapport Ă  ces femmes-lĂ  qui venaient pour les SPrN sans leurs partenaires (106/220 = 48,2% contre 661/1787 = 37,0%, respectivement; OR 1,58, IC Ă  95%: 1.20 Ă  2.10). La participation des hommes semble ĂȘtre un facteur clĂ© dans la recherche de comportement de santĂ© des femmes et pourrait avoir un impact positif sur la morbiditĂ© et la mortalitĂ© maternelle et infantile. Mots-clĂ©s: soins prĂ©natals, le VIH, les hommes, la prestation de service, les soins postnatals, Zambie
