RESUMO

BACKGROUND: The data on epidemiology of Human papillomavirus (HPV) infections in men are scarce relative to women generally, particularly among men engaging in heterosexual relationships. This study investigated the prevalence and risk factors for penile, anal, and oral HPV in men in two communities in Ibadan, Nigeria. METHODS: This was a cross-sectional survey involving a face-to-face interview, a clinical examination, and sample collection from participants. HPV genotyping was performed with Anyplex II 28 HPV assay. The prevalences and factors associated with HPV infections using multivariable models and concordance between sites. RESULTS: Of 316 men, the proportion of any HPV infection in the penile, anal, and oral sites was 40.5%, 9.7%, and 7.8%, respectively. The proportion of any high-risk HPV, low-risk HPV, and multiple HPV infections was highest in the penis followed by the anal and oral sites. Only 5/316 (1.6%) men had concordant HPV in all three sites, with the highest concordance in penile-anal sites relative to penile-oral and anal-oral sites. The odds of penile HPV were higher in men aged 25 years and above. Having penile HPV was associated with higher odds of detecting anal HPV and vice versa. Oral HPV was less likely in men not living with their sexual partners. CONCLUSION: Penile HPV is the most common infection followed by anal HPV and oral HPV infections among heterosexual Nigerian men. Concordant HPV infections was highest in penile-anal sites. Nigerian men, as in other settings, are a reservoir of HPV and it is important to conduct more robust studies to appreciate their role in HPV transmission, epidemiology, and prevention.

RESUMO

AIM: To compare the effectiveness of 50 and 100 µg of carbetocin with 10 IU of oxytocin for the prevention of postpartum hemorrhage (PPH). METHODS: This was a triple-blind, non-inferiority trial involving pregnant women recruited at term. We compared two doses of carbetocin (50 and 100 µg) with 10 IU of oxytocin administered as uterotonic agent after vaginal or cesarean delivery. Uterine contractility was assessed at 2- and 5-min after uterotonic administration. The association between adequate uterine tone and PPH with the patients' characteristics were examined using the chi-square test. Effect of the drugs on the odds of developing PPH was examined using logistics regressions. All analyses were conducted using STATA (StataCorp L.L.C.) with a significance level set at 0.05. RESULTS: In total, 324 women (50 µg carbetocin group-111, 100 µg carbetocin group-106, and oxytocin group-107) participated in the study. There was a significantly higher proportion of women with adequate uterine tone in those that had 100 µg carbetocin relative to 50 µg and 10 IU oxytocin at 5 min (p < 0.001). Patients who received oxytocin had a higher average blood loss than women that had either 50 or 100 µg carbetocin (p = 0.128). There was a significant difference in the need for additional uterotonic, with a higher proportion of participants among those who received 10 IU of oxytocin (p < 0.001). CONCLUSION: Patients that had 100 µg of carbetocin had a better adequate uterine tone at the fifth minute compared to those who had 50 µg and 10 IU of oxytocin. Generally, carbetocin use was less likely associated with risk of PPH and use of additional intervention.

RESUMO

Human papillomavirus infection (HPV) is a significant global public health concern, known to be a leading cause of cancer related death among women in sub-Saharan Africa. This study assessed knowledge of HPV infection, transmission, prevention, and HPV vaccine uptake among tertiary institution students in Plateau State, Nigeria. A cross-sectional study was conducted among students from two tertiary institutions in Plateau State, Nigeria. Using a structured pretested questionnaire, data were collected from participants selected by two-stage sampling technique. Participants' responses were analysed to assess their knowledge regarding HPV transmission, prevention, and vaccination. A composite score was obtained for the general HPV knowledge. A score of more than 70.0% indicated good knowledge. The distribution of the variables was examined using frequency distribution and descriptive statistics. The chi-square test was performed for bivariate analysis. Logistics regression was performed to examine the odds of having good HPV knowledge among the students. Level of significant was set at 95%. Of the 425 participants, 302 (71.1%) were female and 123 (28.9%) were male, with a mean age of 23 ± 2.8 years. There was low awareness of HPV among participants, with higher awareness among the females 66 (23.1%) than the males 26 (22.2%) (p = .853). Both female 77 (26.1%) and male participants 31 (26.72%) had low awareness of HPV vaccination. Among all participants, only 19 (5%) demonstrated good knowledge of HPV. Participants who were employed significantly had good knowledge of HPV compared to those who were unemployed. There was inadequate general knowledge of HPV and its vaccination among tertiary institution students in Plateau State, Nigeria. The students' employment status was associated with their knowledge of HPV. Targeted educational programs focusing on diverse educational levels and institution types are recommended to enhance HPV knowledge and promote vaccine uptake.

RESUMO

Objectives: This study investigates the use of pro- and anti-inflammatory cytokines in predicting the outcome of pregnancy complicated by threatened miscarriage. Materials and Methods: Of the 140 eligible pregnant women recruited for the study, maternal serum levels of selected inflammatory cytokines (IL-2, IFNγ, IL-4, and IL-13) for 70 women with threatened miscarriage were analysed for this study. Serum concentrations were measured using the enzyme-linked immunosorbent assay (ELISA) kit. Inevitable miscarriage or ongoing pregnancy was used as the outcome, whereas serum levels of selected inflammatory cytokines, women's sociodemographic characteristics, gynaecologic history, and clinical history were used as the explanatory variables. The Student's t test was used to compare the cytokine profiles between women with inevitable miscarriages and women with normal ongoing pregnancy after 13 weeks of gestation. Poisson regression models were performed to investigate the factors associated with inevitable miscarriage. Results: The result revealed significantly higher pro-inflammatory cytokines, IL-2 (P < 0.001), and IFNγ (P < 0.001) in women with a pregnancy that resulted in an inevitable miscarriage than in those that resulted in an ongoing pregnancy. The incidence rate of inevitable miscarriage increased by 16% (IRR = 1.16, 95% CI: 0.58-2.32) for a unit increase in IL-2 and by 25% (IRR = 1.25, 95% CI: 1.09-1.43) when adjusted for sociodemographic characteristics, gynaecology, and clinical history. Conclusion: The IL-2 was the best biomarker for predicting the outcome of threatened pregnancy with a sensitivity of 80% and a specificity of 70% at 1.30 pg/mL cut-off point.

RESUMO

Aim: Several studies had investigated the importance and benefit of pelvic floor exercises (PFEs) to the pregnant women and their unborn babies, however, the concerns of antenatal women on the exercise have been sparsely investigated. This study examined the attitude and concerns of pregnant women towards engaging in PFEs in Ibadan, Nigeria. Materials and Methods: This was cross-sectional study of pregnant women aged ≥15 years. Participants were recruited at primary, secondary and tertiary health facilities. A face-to-face interview was conducted using a structured questionnaire with open and close-ended questions for data collection. Bivariate analysis was performed using chi-square and Fisher's exact test to investigate the association between categorical variables. Multivariate analysis was performed with log-binomial and multinomial regressions to select significant variables that affect the attitude of pregnant women. Results: Of the 373 pregnant women recruited, 118 had ever practiced PFEs. A little below average (43%) performed PFE for less than 3 days a week. Ability to have easy childbirth was the most common motivator for practicing PFE. Participants were most concerned about abdominal pain. No association between any of the factors and participants' attitudes. Conclusion: Though there was a positive attitude of pregnant women towards the PFE but the practice was low. This might be due to inadequate availability of information. We recommend health promotional messages to encourage pregnant women to engage in PFE as part of antenatal messages for healthy living.

RESUMO

BACKGROUND: High-quality contraceptive counselling can accelerate global efforts to reduce the unmet need for and suboptimal use of modern contraceptives. This study aims to identify a package of interventions designed to strengthen in Pakistan and Nigeria and determine their effectiveness in increasing client-level decision-making, autonomy and meeting of contraceptive needs. METHODS: A multisite, two-stage and five-phase intervention design will start with a pre-formative, formative, design, experimental and reflective phase. The pre-formative phase will map potential study sites and establish the sampling frame. The two-part formative phase will first use participatory approaches to identify clients' perspectives, including young couples and providers, to ensure research contextualisation and address each interest group's needs and priorities followed by clinical observations of client-provider encounters to document routine care. The design workshop in the third phase will result in the development of a package of contraceptive counselling interventions. In the fourth experimental phase, a multi-intervention, three-arm, single-blinded, parallel cluster randomised-controlled trial will compare routine care (arm 1) with the contraceptive counselling package (arm 2) and the same package combined with wider methods availability (arm 3). The study aims to enrol a total of 7920 participants. The reflective phase aims to identify implementation barriers and enablers. The outcomes are clients' level of decision-making autonomy and use of modern contraceptives. ETHICS AND DISSEMINATION: Ethical approval for this study was obtained from the WHO Scientific and Ethics Review Committee (Protocol ID Pakistan: ERC 006232 and Nigeria ERC: 006523). Each study site is required and has obtained the necessary ethical and regulatory approvals that are required in each specific country. Findings will be presented at local, national and international conferences and disseminated by peer-review publications. TRIAL REGISTRATION NUMBER: NCT06081842.

RESUMO

INTRODUCTION: Sub-Saharan Africa (SSA) regions have the highest burden of cervical cancer (CC), accounting for nearly a quarter of global mortality. Many women in SSA are reluctant to access CC screening because they are uncomfortable exposing their private parts to healthcare providers. The perception of women who have experienced self-sampling in SSA is yet to be reviewed. This scoping review will explore the literature on the perception and attitude of women towards methods of collecting cervicovaginal samples for human papillomavirus (HPV) testing in SSA. METHODS AND ANALYSIS: An extensive search using the Arksey and O'Malley framework will be conducted. The search criteria will be limited to original research conducted in community or clinical settings in SSA within the last 10 years. Four databases, namely, PUBMED, Cochrane, African Journals Online and Google Scholar, will be searched. Two independent persons (UIAB and DOO) will screen the titles and abstracts and later full texts using population, intervention, comparison and outcome criteria. IOMB will serve as a tiebreaker whenever there is no agreement on the choice of eligibility criteria. The screening process will be presented using Preferred Reporting Items for Systematic Reviews and Meta-Analyses for the scoping review flow format. The descriptive analysis of eligible studies for scoping reviews will be summarised. We will describe themes of attitude and perception covering pain, embarrassment, privacy and comfortability, willingness to self-sample, anxiety and confidence. ETHICS AND DISSEMINATION: This is a scoping review protocol and does not require ethical approval. Findings from this review will be disseminated through peer-reviewed publications, the production of policy briefs, and presentations at local and international conferences.

RESUMO

Young adults in tertiary institutions engage in different sexual behaviours including penetrative and non-penetrative sex. This study explored young adults' perceptions, interpretations and implications for engaging in non-penile-vaginal sex (NPVS) in tertiary institutions of Plateau state, in the north-central Zone. An exploratory qualitative research approach was adopted. Eight (8) focus group discussions (FGDs) of singles and married males and females were conducted with seventy-nine (n=79) participants aged 18 - 30 years). Audio files were transcribed, coded, and managed using NVivo 12 software. Thematic analysis was applied to present themes and a description of key findings. Four (4) themes emerged. All groups acknowledged sexual satisfaction and improved intimacy as benefits of NPVS. The sexual orientation of people who partake in NPVS are often misinterpreted. Young adults involved in NPVS face rejection and stigmatization. Lastly, the sexual orientation misinterpretation, rejection and stigma of those who engage in NPVS is likely to be a result of the general believe that Nigeria is conservative in sociocultural values and expression.


Les jeunes adultes des établissements d'enseignement supérieur adoptent différents comportements sexuels, notamment des relations sexuelles avec et sans pénétration. Cette étude a exploré les perceptions, les interprétations et les implications des jeunes adultes concernant la pratique de relations sexuelles non péniennes-vaginales (NPVS) dans les établissements d'enseignement supérieur de l'État du Plateau, dans la zone centre-nord. Une approche de recherche exploratoire qualitative a été adoptée. Huit (8) discussions de groupe (FGD) d'hommes et de femmes célibataires et mariés ont été menées avec soixante-dix-neuf (n = 79) participants âgés de 18 à 30 ans). Les fichiers audio ont été transcrits, codés et gérés à l'aide du logiciel NVivo 12. L'analyse thématique a été appliquée aux thèmes présentés et à une description des principales conclusions. Quatre (4) thèmes ont émergé. Tous les groupes ont reconnu la satisfaction sexuelle et l'amélioration de l'intimité comme avantages du NPVS. L'orientation sexuelle des personnes qui participent aux NPVS est souvent mal interprétée. Les jeunes adultes impliqués dans les NPVS sont confrontés au rejet et à la stigmatisation. Enfin, l'interprétation erronée de l'orientation sexuelle, le rejet et la stigmatisation de ceux qui s'engagent dans les NPVS sont probablement le résultat de la croyance générale selon laquelle le Nigeria est conservateur en termes de valeurs et d'expression socioculturelles.

RESUMO

Background: Since the outbreak of COVID-19 disease, the environment, families, individuals, and their ways of living have been affected. Social distancing was one of the strategies for the prevention of SARS-CoV-2 infection. It led to limited social interactions for fear of contracting the infection, which ultimately affected relationships, among which is sexual health. Aim: To determine the risk of female sexual dysfunction and the effect of the COVID-19 pandemic on sexual function and activities among women of reproductive age in Ibadan, South-West Nigeria. Methods: This cross-sectional study of 218 reproductive-age women evaluated the sexual function before, during, and after the COVID-19 disease pandemic and lockdown. Pretested semistructured self-administered questionnaires with the Female Sexual Function Index (FSFI) were used for data collection. Information collected included sociodemographic and gynecologic characteristics and COVID-19 experiences, as well as sexual history and function before, during, and after the COVID-19 pandemic lockdown. The level of significance was set at P < .05. Outcomes: Respondents were aged 20 to 50 years (95%) with a mean ± SD age of 34.82 ± 8.52 years; the majority were married (75.58%); one-fifth (21.9%) tested positive for COVID-19 infection; and participants who tested positive for COVID-19 infections were mostly health care workers. Results: An absence of sexual activity was reported in 9.18% of participants during lockdown, 7.73% before lockdown, and 4.18% after lockdown. The risk of female sexual dysfunction was prevalent among participants, especially those who tested positive for COVID-19 infection. The prevalence was worse during the pandemic lockdown (53.57%) than before (48.39%) or after (51.61%), and a similar pattern was seen among those who tested negative. There was no statistically significant difference in risk of developing sexual dysfunction during the COVID-19 pandemic between those who tested positive and negative to COVID-19. The arousal and desire domains contributed the highest proportion of low FSFI scores. Clinical Implications: Nationwide lockdowns, which may be a method of control for pandemics, may result in psychosocial complications such as female sexual dysfunction. Strength and Limitations: Most respondents had tertiary education and were able to respond to self-administered questionnaires, yet the risk of recall bias remains a concern whereas the pandemic met the world unprepared and baseline FSFI prior the pandemic was not available for participants. There are no local validation studies for the FSFI in Nigeria, which could have aided interpretation of results. Conclusion: A low FSFI score is prevalent in Ibadan, South-West Nigeria, with a higher incidence reported during the COVID-19 pandemic lockdown.

RESUMO

OBJECTIVE: To compare the levels of proinflammatory cytokines in women with threatened miscarriage and normal pregnancy. METHODS: This study was a longitudinal study. Consenting women with normal pregnancy and those admitted on account of threatened miscarriage at an estimated gestational age of 6-10 weeks were included in the study. The proinflammatory cytokines interleukin-2 (IL-2) and interferon-γ (IFN-γ) and the anti-inflammatory cytokines IL-4 and IL-13 were measured at the diagnosis of threatened miscarriage (baseline) and in the 13th week of pregnancy. The χ2 test of association was used to examine the relationship between the pregnancy type and demographic characteristics; clinical history and gynecologic history. Student t test was used to compare the selected cytokine between women with threatened miscarriage and normal pregnancy. RESULTS: There was a significantly higher IL-2 (P = 0.033), IFN-γ (P < 0.001), and IL-13 (P < 0.001) in women with threatened miscarriage than in women with normal pregnancy at the baseline. At the follow up, the results revealed a significantly higher IFN-γ level (P < 0.001) and IL-4 (P = 0.019) in women with threatened miscarriage than in women with normal pregnancies. CONCLUSION: Proinflammatory cytokine profiles were associated with a higher risk of threatened miscarriage.

RESUMO

Over the past three decades, substantial progress has been made in reducing maternal mortality worldwide. However, the historical focus on mortality reduction has been accompanied by comparative neglect of labour and birth complications that can emerge or persist months or years postnatally. This paper addresses these overlooked conditions, arguing that their absence from the global health agenda and national action plans has led to the misconception that they are uncommon or unimportant. The historical limitation of postnatal care services to the 6 weeks after birth is also a contributing factor. We reviewed epidemiological data on medium-term and long-term complications arising from labour and childbirth beyond 6 weeks, along with high-quality clinical guidelines for their prevention, identification, and treatment. We explore the complex interplay of human evolution, maternal physiology, and inherent predispositions that contribute to these complications. We offer actionable recommendations to change the current trajectories of these neglected conditions and help achieve the targets of Sustainable Development Goal 3. This paper is the third in a Series of four papers about maternal health in the perinatal period and beyond.

RESUMO

BACKGROUND: Benign prostatic hyperplasia (BPH) is a major health concern associated with lower urinary tract symptoms and sexual dysfunction in men. Recurrent inflammation, decreased apoptotic rate and oxidative stress are some of the theories that explain the pathophysiology of BPH. Common salt, a food additive, is known to cause systemic inflammation and redox imbalance, and may serve as a potential risk factor for BPH development or progression. This study examined the effect of common salt intake on the pathology of testosterone-induced BPH. METHODS: Forty male Wistar rats were randomly divided into four equal groups of 10: a control and three salt diet groups-low-salt diet (LSD), standard-salt diet (SSD) and high-salt diet (HSD). The rats were castrated, allowed to recuperate and placed on salt-free diet (control), 0.25% salt diet (LSD), 0.5% salt diet (SSD) and 1.25% salt diet (HSD) for 60 days ad libitum. On day 33, BPH was induced in all the rats with daily injections of testosterone propionate-Testost® (3 mg/kg body weight) for 28 days. The rats had overnight fast (12 h) on day 60 and were euthanized the following day in order to collect blood and prostate samples for biochemical, molecular and immunohistochemistry (IHC) analyses. Mean ± SD values were calculated for each group and compared for significant difference with ANOVA followed by post hoc test (Tukey HSD) at p < 0.05. RESULTS: This study recorded a substantially higher level of IL-6, IL-8 and COX-2 in salt diet groups and moderate IHC staining of COX-2 in HSD group. The prostatic level of IL-17, IL-1ß, PGE2, relative prostate weight and serum PSA levels were not statistically different. The concentrations of IGF-1, TGF-ß were similar in all the groups but there were multiple fold increase in Bcl-2 expression in salt diet groups-LSD (13.2), SSD (9.5) and HSD (7.9) and multiple fold decrease in VEGF expression in LSD (-6.3), SSD (-5.1) and HSD (-14.1) compared to control. Activity of superoxide dismutase (SOD) and concentration of nitric oxide rose in LSD and SSD groups, and SSD and HSD groups respectively. Activities of glutathione peroxidase and catalase, and concentration of NADPH and hydrogen peroxide were not significantly different. IHC showed positive immunostaining for iNOS expression in all the groups while histopathology revealed moderate to severe prostatic hyperplasia in salt diet groups. CONCLUSIONS: These findings suggest that low, standard and high salt diets aggravated the pathology of testosterone-induced BPH in Wistar rats by promoting inflammation, oxidative stress, while suppressing apoptosis and angiogenesis.

RESUMO

BACKGROUND: High risk human papillomaviruses (HR-HPV) have a causal role in cervical oncogenesis, and HIV-mediated immune suppression allows HR-HPV to persist. We studied whether vaginal microbiome community state types (CSTs) are associated with high-grade precancer and/or invasive cervical cancer (HSIL/ICC). METHODS: This was a cross-sectional study of adult women with cervical cancer screening (CCS) at the Jos University Teaching Hospital (JUTH) in Jos, Nigeria, between January 2020 and February 2022. Cervical swabs underwent HPV genotyping (Anyplex™ II HPV28). Cervico-vaginal lavage (CVL) sample was collected for 16 S rRNA gene amplicon sequencing. We used multivariable logistic regression modelling to assess associations between CSTs and other factors associated with HSIL/ICC. RESULTS: We enrolled 155 eligible participants, 151 with microbiome data for this analysis. Women were median age 52 (IQR:43-58), 47.7% HIV positive, and 58.1% with HSIL/ICC. Of the 138 with HPV data, 40.6% were negative for HPV, 10.1% had low-risk HPV, 26.8% had single HR-HPV, and 22.5% had multiple HR-HPV types. The overall prevalence of any HR-HPV type (single and multiple) was 49.3%, with a higher proportion in women with HSIL/ICC (NILM 31.6%, LSIL 46.5%, HSIL 40.8%, and 81.5% ICC; p = 0.007). Women with HIV were more likely to have HSIL/ICC (70.3% vs. 29.7% among women without HIV). In crude and multivariable analysis CST was not associated with cervical pathology (CST-III aOR = 1.13, CST-IV aOR = 1.31). However, in the presence of HR-HPV CST-III (aOR = 6.7) and CST-IV (aOR = 3.6) showed positive association with HSIL/ICC. CONCLUSION: Vaginal microbiome CSTs were not significantly associated with HSIL/ICC. Our findings suggest however, that CST could be helpful in identifying women with HSIL/ICC and particularly those with HR-HPV. Characterization of CSTs using point-of-care molecular testing in women with HR-HPV should be studied as an approach to improve early detection and cervical cancer prevention. Future longitudinal research will improve our understanding of the temporal effect of non-optimal CST, HR-HPV, and other factors in cervical cancer development, prevention, and control.

RESUMO

Self-report of uterine fibroids (UF) has been used for epidemiologic research in different environments. Given the dearth of studies on the epidemiology of UF in Sub-Saharan Africa (SSA), it is valuable to evaluate its performance as a potential tool for much needed research on this common neoplasm in SSA women. We conducted a cross-sectional study of self-report of UF compared with transvaginal ultrasound diagnosis (TVUS) among 486 women who are members of the African Collaborative Center for Microbiome and Genomics Research (ACCME) Study Cohort in central Nigeria. We used log-binomial regression models to compute the classification, sensitivity, specificity, and predictive values of self-report compared to TVUS, adjusted for significant covariates. The prevalence of UF on TVUS was 45.1% (219/486) compared to 5.4% (26/486) based on self-report of abdominal ultrasound scan and 7.2% (35/486) based on report of healthcare practitioner's diagnosis. Self-report correctly classified 39.5% of the women compared to TVUS in multivariable adjusted models. The multivariable adjusted sensitivity of self-report of healthcare worker diagnosis was 38.8%, specificity was 74.5%, positive predictive value (PPV) was 55.6%, and negative predictive value (NPV) was 59.8%. For self-reported abdominal ultrasound diagnosis, the multivariable adjusted sensitivity was 40.6%, specificity was 75.3%, PPV was 57.4%, and NPV was 60.6%. Self-report significantly underestimates the prevalence of UF and is not accurate enough for epidemiological research on UF. Future studies of UF should use population-based designs and more accurate diagnostic tools such as TVUS.

RESUMO

BACKGROUND: Sub-Saharan Africa (SSA) has the highest cervical cancer (CC) burden globally-worsened by its HIV epidemics. In 2020, the World Health Organization (WHO) introduced a CC elimination strategy with goals for vaccination, screening, and treatment. To benchmark progress, we examined temporal trends in screening coverage, percent screened at least twice by the age of 45, screening coverage among women living with HIV (WLHIV), and pre-cancer treatment coverage in SSA. METHODS AND FINDINGS: We conducted a systematic analysis of cross-sectional population-based surveys. It included 52 surveys from 28 countries (2000 to 2020) with information on CC screening among women aged 25 to 49 years (N = 151,338 women). We estimated lifetime and past 3-year screening coverage by age, year, country, and HIV serostatus using a Bayesian multilevel model. Post-stratification and imputations were done to obtain aggregate national, regional, and SSA-level estimates. To measure re-screening by age 45, a life table model was developed. Finally, self-reported pre-cancer treatment coverage was pooled across surveys using a Bayesian meta-analysis. Overall, an estimated 14% (95% credible intervals [95% CrI]: 11% to 21%) of women aged 30 to 49 years had ever been screened for CC in 2020, with important regional and country-level differences. In Eastern and Western/Central Africa, regional screening coverages remained constant from 2000 to 2020 and WLHIV had greater odds of being screened compared to women without HIV. In Southern Africa, however, screening coverages increased and WLHIV had equal odds of screening. Notably this region was found to have higher screening coverage in comparison to other African regions. Rescreening rates were high among women who have already been screened; however, it was estimated that only 12% (95% CrI: 10% to 18%) of women had been screened twice or more by age 45 in 2020. Finally, treatment coverage among 4 countries with data was 84% (95% CrI: 70% to 95%). Limitations of our analyses include the paucity of data on screening modality and the few countries that had multiple surveys. CONCLUSION: Overall, CC screening coverage remains sub-optimal and did not improve much over the last 2 decades, outside of Southern Africa. Action is needed to increase screening coverage if CC elimination is to be achieved.

RESUMO

BACKGROUND: Age-specific data on anal, and corresponding cervical, human papillomavirus (HPV) infection are needed to inform female anal cancer prevention. METHODS: We centrally reanalyzed individual-level data from 26 studies reporting HPV prevalence in paired anal and cervical samples by human immunodeficiency virus (HIV) status and age. For women with HIV (WWH) with anal high-grade squamous intraepithelial lesions or worse (HSIL+), we also investigated concurrent cervical cytopathology. RESULTS: In HIV-negative women, HPV16 prevalence decreased significantly with age, both at anus (4.3% at 15-24 years to 1.0% at ≥55 years; ptrend = 0.0026) and cervix (7.4% to 1.7%; ptrend < 0.0001). In WWH, HPV16 prevalence decreased with age at cervix (18.3% to 7.2%; ptrend = 0.0035) but not anus (11.5% to 13.9%; ptrend = 0.5412). Given anal HPV16 positivity, concurrent cervical HPV16 positivity also decreased with age, both in HIV-negative women (ptrend = 0.0005) and WWH (ptrend = 0.0166). Among 48 WWH with HPV16-positive anal HSIL+, 27 (56%) were cervical high-risk HPV-positive, including 8 with cervical HPV16, and 5 were cervical HSIL+. CONCLUSIONS: Age-specific shifts in HPV16 prevalence from cervix to anus suggest that HPV infections in the anus persist longer, or occur later in life, than in the cervix, particularly in WWH. This is an important consideration when assessing the utility of cervical screening results to stratify anal cancer risk.

RESUMO

Although heterosexual oral and anal sexual behaviors have been reported in sub-Saharan Africa, little is known about how they are understood and perceived, particularly, in West Africa. We undertook a qualitative exploration of local terminologies and sexual scripts associated with heterosexual oral and anal sex in preparation for a quantitative survey. We held focus group discussions (18) and interviews (44) with younger and middle-aged men and women from the general population and female sex workers (FSWs) in selected communities in Ibadan. Most participants had heard of oral and anal sex. Younger adults aged 18-25 years, particularly male participants and FSWs, appeared more informed than older adults in the general population. Sexually explicit movies were the most cited source of information. Oral and anal sexual behaviors were considered sensitive, with different local names, meanings, and interpretations. Participants advised against the use of slang terms in research. We identified six different scripts employed by participants in discussing oral and anal sex practices: protecting sexual relationship, financial reward, an alternative to vaginal sex, pleasure, male dominance and control, and risk, stigma, and disgust.

RESUMO

Mass vaccination against COVID-19 is the best method to ensure herd immunity in order to curb the effect of the pandemic on the global economy. It is therefore important to assess the determinants of COVID-19 vaccine acceptance and hesitancy on a global scale. Factors were recorded from cross-sectional studies analyzed with t-Test, ANOVA, correlation, and meta-regression analyses and synthesized to identify global trends in order to inform policy. We registered the protocol (ID: CRD42022350418) and used standard Cochrane methods and PRISMA guidelines to collect and synthesize cross-sectional articles published between January 2020 and August 2023. A total of 67 articles with 576 studies from 185 countries involving 3081,766 participants were included in this synthesis. Global COVID-19 vaccine acceptance was 65.27% (95% CI; 62.72-67.84%), while global vaccine hesitancy stood at 32.1% (95% CI; 29.05-35.17%). One-Way ANOVA showed that there was no significant difference in the percentage Gross Domestic Product spent on vaccine procurement across the World Bank income levels (p < 0.187). There was a significant difference of vaccine acceptance (p < 0.001) and vaccine hesitancy (p < 0.005) across the different World Bank Income levels. World Bank income level had a strong influence on COVID-19 vaccine acceptance (p < 0.0004) and hesitancy (p < 0.003) but percentage Gross Domestic Product spent on vaccine procurement did not. There was no correlation between percentage Gross Domestic Product spent on vaccine procurement and COVID-19 vaccine acceptance (r = -0.11, p < 0.164) or vaccine hesitancy (r = -0.09, p < 0.234). Meta-regression analysis showed that living in an urban setting (OR = 4.83, 95% CI; 0.67-212.8), rural setting (OR = 2.53, 95% CI; 0.29-119.33), older (OR = 1.98, 95% CI; 0.99-4.07), higher education (OR = 1.76, 95% CI; 0.85-3.81), and being a low income earner (OR = 2.85, 95% CI; 0.45-30.63) increased the odds of high COVID-19 vaccine acceptance. Factors that increased the odds of high COVID-19 vaccine hesitancy were no influenza vaccine (OR = 33.06, 95% CI; 5.03-1395.01), mistrust for vaccines (OR = 3.91, 95% CI; 1.92-8.24), complacency (OR = 2.86, 95% CI; 1.02-8.83), pregnancy (OR = 2.3, 95% CI; 0.12-141.76), taking traditional herbs (OR = 2.15, 95% CI; 0.52-10.42), being female (OR = 1.53, 95% CI; 0.78-3.01), and safety concerns (OR = 1.29, 95% CI; 0.67-2.51). We proposed a number of recommendations to increase vaccine acceptance and ensure global herd immunity against COVID-19.

RESUMO

INTRODUCTION: Anaemia remains a major public health concern, particularly, in sub-Saharan Africa (SSA), where it is one of the causes of maternal death. The most common cause of maternal anaemia is iron deficiency or malnutrition. This study examined the prevalence of and risk factors for anaemia among women that participated in the Nigerian Demographic Health Survey. METHOD: We used data of 14,454 women that participated in the 2018 Nigeria Demographic and Health Survey (NDHS). We extracted information such as demographic, social and housing, dietary characteristics and haemoglobin concentration. The descriptive statistic results, prevalence and 95% confidence interval (CIs) of anaemia with the selected respondents background characteristics were presented. The Poisson regression model with robust variance was used to assess the risk of anaemia among women of reproductive age. All analyses were weighted and adjusted for the complex survey design. Statistical significance was interpreted at p value < 0.05. RESULTS: Maternal status, body mass index, education, residence, religion, ethnicity, region and type of cooking fuel were all important determinants of anaemia. The prevalence of anaemia was high among pregnant women (61.8%; 95% CI: 58.5-65.0), adolescents (60.4%; 95% CI: 58.1-62.6), underweight women (62.6%; 95% CI: 59.5-65.5), women who had no formal education (64.1%; 95% CI: 62.2-66.0) and those who belonged to the poorest wealth quintile (65.8%; 95% CI: 63.1-68.4). Similarly, anaemia was high among women residing in rural areas (61.5%; 95% CI: 60.0-63.0), Muslims (59.9%; 95% CI: 58.1-61.6) and women with six or more children (62.1%; 95% CI: 60.0-64.1). The risk of anaemia were 2% less likely among women who took minimum adequate diet compared to those who do not. CONCLUSION: To date, this is the largest data on maternal anaemia in Nigeria. The study highlighted the high burden of maternal anaemia in the country and different risk factors (medical and social) that are associated with this medical condition among women of reproductive age. We recommend future longitudinal studies to test hypothesis in order to assess whether there is any causal relationship between identified risk factors and anaemia in this group of women.

RESUMO

Background: COVID-19 lockdown was associated with disruption of daily life, economy, essential health services including maternal health service, and psychological reflexes such as panic, sleep disorders, fear, anxiety, and depression. Aim: To assess the perception of pregnant women on the COVID-19 pandemic lockdown and the prevalence of common mental health disorders (CMHD) among pregnant women. Methods: A cross-sectional study was conducted among 380 pregnant women at the University College Hospital (UCH) Ibadan; participants were enrolled using a simple random sampling technique. Data was collected using pretested interviewer-administered questionnaire. Information obtained - sociodemographic and obstetric characteristics, perception and reaction to the COVID-19 pandemic and lockdown, effect on ANC, coping mechanisms, and presence of CMHD (anxiety and depression) were measured using Hospital Anxiety and Depression Scale (HADS). Data were analysed using STATA 16.0 Software. Descriptive and bivariate statistics were performed. The level of significance was p-value < 0.05. Results: The mean age was 32 ± 4.78 years, most respondents were <35 years (75%), married (97.1%), had a higher education (89%) and multiparous (70%). About 43.9% were worried that COVID-19 would affect pregnancy care, 42.9% reported it affected care and 81.6% were not worried it would affect the delivery care. Among respondents, 96.6% were able to cope with the effects of the pandemic and 96.8% enjoyed good social support. Respondents did not have CMHD (88.16%), 7.9% had CMHD (4.74% had depression and 3.16% had anxiety) and 3.95% had co-morbid depression and anxiety. On multinomial regression analysis, relative to anxiety or depression only, respondents with combined depression and anxiety had higher odds of having no delivery plan and thought COVID-19 may affect their delivery. Conclusion: Only a few women reported anxiety and depression symptoms during the lockdown and those with anxiety or combined symptoms of anxiety and depression had no birth plan and believed that COVID-19 would affect their delivery.
