Oral health behavior of pregnant women in Nigeria: a scoping review.

BACKGROUND: Oral health care behaviors during pregnancy affects maternal and child health outcomes. This scoping review sought to map the existing literature on the oral healthcare behaviors of pregnant women in Nigeria. METHODS: PubMed, Science Direct, Web of Science, EBSCOHOST, Sabinet, African Index Medicus, and Scopus data based were searched in August 2023. Articles with reports on the oral health behavior of pregnant women in Nigeria, published in English in peer review were included in the review. Articles whose full lengths could not be accessed, and commentaries on studies, and letters to the editor were also excluded. Data on authors and year of publication of the study, study location, study objective, study design, methodological approach for data collection, and study outcomes were extracted and descriptively synthesized. RESULTS: The search yielded a total of 595 articles of which 573 were unique. Only 21 articles were left after titles and abstracts screening and only 18 articles met the eligibility criteria. The proportion of pregnant women had utilized dental services ranged from 4 to 62.9%, the use of toothbrush and toothpaste ranged from 59.6 to 99.3%, twice daily tooth brushing ranged from 5.2 to 66.9%, and the use of toothbrush among pregnant women in the studies varies from 70.9 to 100%. Chewing stick was used by 0.1-27.7% of study participants. Dental problems such as caries, pain, swollen gums, and excessive salivation were reasons for seeking dental care. We identified individual, structural, and behavioral factors, including myths as barriers for dental service utilization. CONCLUSION: This scoping review shows that dental service utilization by pregnant women in Nigeria is poor and mainly due to curative than preventive needs. Oral health behaviours also need to be improved through tailored oral health education accessible to pregnant women in Nigeria.

Prevalence and associated risk factors for noma in Nigerian children: a systematic review and meta-analysis.

OBJECTIVES: To determine the prevalence, case-fatality rate, and associated risk-factors of Noma in children in Nigeria. METHODS: Search was conducted in PubMed, Google Scholar, and Cochrane Library databases. Data were extraction using a double-blind approach. Discrepancies were resolved by a third reviewer. Heterogeneity was evaluated using I2 statistics. Random-effects model was used for the meta-analysis and subgroup analysis was conducted. The study quality was evaluated using standard Critical-Appraisal-Checklist. RESULTS: Of the 1652 articles identified, 12 studies that met the inclusion criteria included 871 cases of Noma. Two studies had high-risk of bias and were excluded in the meta-analysis. Pooled prevalence of Noma was 2.95% (95%CI:2.19-3.71; Z = 7.60; p < 0.00001, I2:100.0). Case fatality was reported in one study. Sex-distribution had a male-to-female ratio of 1.1:1. Malnutrition (88.42%, 95%CI:52.84-124.00; I2:100.0), measles (40.60%; 95% CI:31.56-49.65; I2:100.0) and malaria (30.75%; 95% CI:30.06-31.45; I2:100.0) were the most notable associated risk-factors. Prevalence of Noma was non-significantly lower in southern (1.96%,95%CI:1.49-2.44;6 studies) than in northern (4.43%; 95%CI:-0.98-9.83; 4 studies) Nigeria. One study reported the prevalence of Noma in children younger than 5 years. CONCLUSIONS: About every 3 in 100 children in Nigeria had Noma and the prevalence was non-significantly higher in northern than southern Nigeria. Malnutrition, measles, and malaria were major associated risk-factors. Case-fatality rate and prevalence based on different age-groups were inconclusive.

Sexual dysfunction among Nigerian women living with HIV infection.

INTRODUCTION: Sexual dysfunction in women with HIV is a necessary but understudied aspect of HIV complications in women living with HIV. This study reports the prevalence, pattern, and risk factors for sexual dysfunction in women living with HIV in southwest Nigeria. METHODS: A validated Female Sexual Function Index was used to determine sexual dysfunction in a cross-sectional study design involving 2926 adult women living with HIV in a large, publicly funded tertiary HIV treatment centre in Lagos, Nigeria. A score of less than 26.5 indicated sexual dysfunction. Multivariate logistic regression analysis was performed to identify risk factors for sexual dysfunction. P<0.05 was considered statistically significant at a 95% confidence interval (CI). RESULTS: The prevalence of sexual dysfunction was 71.4%. The types of dysfunctions detected included disorder of desire (76.8%), sexual arousal (66.0%), orgasm (50.0%), pain (47.2%), lubrication (47.2%), and satisfaction (38.8%). Multivariate analysis showed that menopause (aOR: 2.0; 1.4-4.1), PHQ score of 10 and above (aOR: 2.3; 1.7-3.2), co-morbid medical conditions (aOR: 1.8; 1.4-2.7), use of protease inhibitor-based antiretroviral therapy (aOR: 1.3; 1.2-2.1) and non-disclosure of HIV status (aOR: 0.7; 0.6-0.8) were factors associated with sexual dysfunction. CONCLUSIONS: Sexual dysfunction is common among Nigerian women living with HIV. Menopause, use of protease inhibitor-based regimens, PHQ score of at least 10, co-morbid medical condition, and non-disclosure of HIV status were associated with sexual dysfunction. National HIV programmes, in addition to incorporating screening and management of sexual dysfunction in the guidelines, should sensitise and train health workers on the detection and treatment of sexual dysfunction.

Determinants and Patterns of Contraceptive Use among Sexually Active Women Living with HIV in Ibadan, Nigeria.

Background: Contraception is a strategy to meet the family planning goals of women living with human immunodeficiency virus (WLHIV) as well as to reduce the transmission of HIV. There is limited data from Nigeria, where HIV prevalent is the second-largest in the world. This study aimed to examine contraceptive use and identify factors influencing its use among sexually active WLHIV in Ibadan, Nigeria. Methods: A facility-based cross-sectional study was conducted among 443 sexually active WLHIV across three HIV treatment centers in Ibadan, Oyo State. The inclusion criteria were WLHIV, aged 18-49 years, who asserted being fecund and sexually active. An adopted questionnaire was used to collect data, and the data was analyzedusing the Statistical Package for Social Sciences (SPSS) Windows version 25. Statistical significance was set at p < 0.05. Results: Among sexually active WLHIV (n = 443), 73.1% used contraceptives, with 26.9% having unmet needs. The results revealed a significant association between employment status and the use of contraceptives (AOR = 2.150; 95% CI 1.279-3.612 p=0.004); accessibility to contraceptive methods and the use of contraceptives (AOR = 21.483; 95% CI 7.279-63.402 p=0.00). Also, a significant association was found between payment for service and contraceptive use (AOR = 14.343; 95% CI 2.705-76.051; p = 0.003). Previous reactions towards contraceptive use were also significantly associated with contraceptive use (AOR = 14.343; 95% CI 2.705-76.051 p = 0.003). The dual contraceptives usage rate was 30.7%. Conclusions: Although contraceptive use among sexually active WLHIV was high, the study highlighted the need for increased adoption of dual contraceptive methods to mitigate the risk of unintended pregnancy and HIV re-infection among this population. It emphasized the importance of continuous sensitization and counseling services healthcare providers provide to promote contraceptive use among WLHIV.

Developing a database for Rett syndrome research performed in the European Union: A resource for researchers and stakeholders.

BACKGROUND: For most rare diseases, which are often significantly under-resourced, sufficient information on funding landscape is missing, which may prevent effective use of research resources and be an obstacle to making effective decisions on research. The objective of this research was to create a database of Rett syndrome research projects carried out in the European Union (EU) and to provide a research landscape analysis. METHOD: Websites of organizations funding research projects were identified and systematically checked. Projects were analysed by date, place, funder types, and research topics. RESULTS: The analysis revealed that the total expenditure on Rett syndrome research was almost €70 million, allocated among 247 projects mostly performed in Italy and the United Kingdom. The main research sponsor was the European Commission. Highlighting research trends and gaps, this work facilitates changes in rare disease research data management. CONCLUSION: This work demonstrates the feasibility of creating an EU-based research database on Rett syndrome projects. It provides a source of information on research development which is useful for individuals, organizations and key players in the private and public sector to make progressive decisions on Rett syndrome research.

Patent landscape of neglected tropical diseases: an analysis of worldwide patent families.

BACKGROUND: "Neglected Tropical Diseases" (NTDs) affect millions of people in Africa, Asia and South America. The two primary ways of strategic interventions are "preventive chemotherapy and transmission control" (PCT), and "innovative and intensified disease management" (IDM). In the last 5 years, phenomenal progress has been achieved. However, it is crucial to intensify research effort into NTDs, because of the emerging drug resistance. According to the World Health Organization (WHO), the term NTDs covers 17 diseases, namely buruli ulcer, Chagas disease, dengue, dracunculiasis, echinococcosis, trematodiasis, human African trypanosomiasis, leishmaniasis, leprosy, lymphatic filariasis, onchocerciasis, rabies, schistosomiasis, soil-transmitted helminthes, taeniasis, trachoma, and yaws. The aim of this study is to map out research and development (R&D) landscape through patent analysis of these identified NTDs. To achieve this, analysis and evaluation have been conducted on patenting trends, current legal status of patent families, priority countries by earliest priority years and their assignee types, technological fields of patent families over time, and original and current patent assignees. MAIN BODY: Patent families were extracted from Patseer, an international database of patents from over 100 patent issuing authorities worldwide. Evaluation of the patents was carried out using the combination of different search terms related to each identified NTD. In this paper, a total number of 12,350 patent families were analyzed. The main countries with sources of inventions were identified to be the United States (US) and China. The main technological fields covered by NTDs patent landscape are pharmaceuticals, biotechnology, organic fine chemistry, analysis of biological materials, basic materials chemistry, and medical technology. Governmental institutions and universities are the primary original assignees. Among the NTDs, leishmaniasis, dengue, and rabies received the highest number of patent families, while human African trypanosomiasis (sleeping sickness), taeniasis, and dracunciliasis received the least. The overall trend of patent families shows an increase between 1985 and 2008, and followed by at least 6 years of stagnation. CONCLUSION: The filing pattern of patent families analyzed undoubtedly reveals slow progress on research and development of NTDs. Involving new players, such as non-governmental organizations may help to mitigate and reduce the burden of NTDs.
