Background: Intestinal worm infections are a significant public health concern for pregnant women in low- and middle-income countries. These infections can lead to anaemia, malnutrition, and adverse pregnancy outcomes, including premature birth and low birth weight. Deworming medication during pregnancy is a safe and effective strategy to prevent these complications and improve maternal and child health. This study aims to investigate the trends and inequalities in the use of deworming medication during pregnancy among women in Sierra Leone between 2008 and 2019.

Methods: The study utilised data from the Sierra Leone Demographic Health Surveys conducted in 2008, 2013, and 2019. We used the Health Equity Assessment Toolkit developed by the World Health Organisation to calculate various measures of inequality, including difference, ratio, population attributable risk, and population attributable fraction. An inequality assessment was conducted for five stratifiers: age, economic status, level of education, place of residence, and sub-national province.

Results: The prevalence of deworming medication during pregnancy was 43.8% in 2008, 72.4% in 2013, and 83.5% in 2019 in Sierra Leone. There was a decrease in age-related inequality from a difference of 3.7% in 2008 to -0.8% in 2019. Economic-related inequality increased from a difference of -8.5% in 2008 to -8.2% in 2019. Both population attributable fraction and population attributable risk were zero in all survey years for economic status, indicating no improvement in the setting average without economic-related inequality. Inequality in education increased from a difference of -8.9% in 2008 to -8.4% in 2019 and decreased from a difference of -2.6% in 2008 to -5.5% in 2019 for place of residence. Provincial inequality decreased from a difference of 29.5% in 2008 to 11.8% in 2019. The population attributable risk for province reveals that the setting average could have been 10.5 percentage points lower in 2008, 8.2 percentage points lower in 2013, and 5.9 percentage points lower in 2019 without provincial inequality.

Conclusion: The prevalence of deworming medication use during pregnancy substantially increased from 2008 to 2019 (43.8% to 83.5%) in Sierra Leone. This suggests a positive public health trend in maternal healthcare access and education. Inequalities related to economic status and education increased slightly while age-related, place of residence and provincial inequalities decreased. This indicates an inequitable distribution of this essential healthcare intervention across these stratifiers. The government and policymakers should continue efforts to raise awareness and promote the use of deworming medication during pregnancy.

The study by Mwatenga et al. found a tuberculosis (TB) prevalence of 10.2% and an HIV prevalence of 19.1% among inmates, with all TB cases co-infected with HIV. Education level, smoking history, and substance use are key predictors of coinfections. Although informative, its single-centred design and reliance on sputum samples may be insufficient for some patient groups, potentially compromising diagnostic accuracy. Expanding the study to include several jails and employing more diagnostic procedures may increase reliability and the ability to generalize. The report also notes the lack of debate on broader socioeconomic variables and structural barriers to healthcare in jails, which are crucial to understanding inmates' health challenges. Overcrowding, malnutrition, and a poor healthcare system are examples of environmental factors that probably contribute to the spread of tuberculosis and make managing HIV more difficult. Additionally, not enough is known about the dietary habits of prisoners and other health conditions like diabetes or mental health, which may have an impact on the course of HIV and TB. Future studies should take these extra characteristics into account to create more comprehensive approaches to controlling HIV coinfections and TB in prison populations. This will help build more effective therapies.

We read the article "Fetal Femur Length and Risk of Diabetes in Adolescence: A Prospective Cohort Study" by Sayeed et al. with great interest. The authors present compelling evidence linking mid-trimester impaired femur growth with elevated prediabetic biomarkers in Bangladeshi adolescents. However, we believe the study would benefit from considering additional factors. Maternal gestational diabetes, a well-known risk factor for type 2 diabetes mellitus (T2DM) in offspring, and family history of diabetes, which reflects genetic predisposition, should be included. Socioeconomic factors, which influence health outcomes, also warrant attention. Including these variables would provide a more comprehensive understanding of the relationship between fetal femur length and T2DM risk in adolescents.

Background: Tungiasis, an ectoparasitic disease caused by sand fleas, causes suffering to millions of people in the tropics. Although the Kenyan National Policy Guidelines list tungiasis treatments as including disinfectants, flea repellents, and botanical oil, the insufficient knowledge and financial constraints of affected communities have led to neglect and inappropriate self-treatment. Current reports show insignificant progress on educational activities at the community level. Therefore, we investigated community residents' treatment-seeking behaviour concerning tungiasis, using an endemic area of Kenya as the research setting.

Methods: A cross-sectional mixed-methods design was employed. Quantitative data were collected from the participants-410 adults who had experienced tungiasis-using a questionnaire, while qualitative data were collected from 20 older adults to 10 medical staffs using semi-structured individual interviews. The study was conducted in two sub-counties of Homa Bay County, Kenya.

Results: Factors significantly correlated with using non-guideline-listed treatments for tungiasis were 'not knowing the causse of tungiasis', 'not seeking treatment from healthcare facilities and traditional healers', and 'wait and see to prevent infection in non-affected members'. The interviews with the older adults revealed 19 self-treatment options for tungiasis, and 40% of the participants opted for self-removal using sharp objects. Only two of these treatments were listed in the guidelines. The most frequently mentioned reason for using a self-treatment option was 'Someone else's idea'. The most frequently mentioned reason for choosing the best self-treatment option was 'Effectiveness'. Interviews with medical staff revealed 11 treatment options; only five of these treatments are listed in the guidelines. The most frequently mentioned reason for selecting/using the treatment was 'Supply situation'.

Conclusions: Residents' socioeconomic factors, cultural factors, and access to appropriate treatment, as well as knowledge of medical staff were significant factors that influenced the residents' tungiasis treatment-seeking behaviours. This study provides feasibility and baseline data to establish an effective, safe, and sustainable treatment for tungiasis.

Background: Gestational diabetes mellitus (GDM) is any degree of glucose intolerance first recognized during pregnancy. GDM awareness among pregnant women translates into GDM prevention and early diagnosis.

Objective: To establish the underlying factors influencing GDM Knowledge Attitude and Practices (KAP) among pregnant women at Kinango District Hospital.

Method: An explanatory mixed-methods design was implemented by initially assessing GDM KAP quantitatively [QUAN], followed by the qualitative [qual] exploration of contextual factors behind quantitative results. In the [QUAN] strand, 354 pregnant women were interviewed from January to February 2019. Thereafter, in the [qual] strand, key informant interviews were conducted among four pregnant women and three healthcare workers; a focus group discussion was held among nine pregnant women, from May to June 2019. STATA V15 software package was used to analyze the quantitative data. Qualitative data were analyzed manually using thematic analysis.

Result: Among 354 pregnant women, 29.0% were knowledgeable, 46.98% had good attitude and 60.17% had good practice. Attending at least one antenatal clinic visit and having heard about diabetes mellitus were associated with good GDM attitude and practices. Among the knowledgeable pregnant women, one-third (33.33%) obtained GDM information from a health facility. Discussions with pregnant women and the interviews with healthcare workers highlighted that daily health talks during antenatal clinic, included GDM and diabetes mellitus information. Furthermore, attendance of at least one antenatal clinic visit was low (85.88%), among pregnant women (87.86%) who were expected to have attended at least one antenatal clinic visits.

Conclusion: Despite low GDM knowledge, pregnant women had relatively good GDM attitudes and good GDM practices. Daily health talks conducted during antenatal clinic as well as indigenous knowledge among pregnant women, influenced the latter. Hence, GDM information dissemination needs to be enhanced for the improvement of GDM KAP among pregnant women for GDM prevention.

Background: Early sexual debut is a widely recognized public health issue due to its influence on lifetime multiple sexual partners which can lead to complications such as teenage pregnancy, abortion, HIV/AIDS and other sexually transmitted infections. However, there is paucity of research evidence on sexual behaviour such as age at first sexual intercourse and the number of sexual partnerships among adolescent girls in Ghana. This study aims to examine the influence of age at first sexual intercourse and other determinants on multiple sexual partnerships among adolescent girls aged 15-19 years in Ghana.

Methods: Data for this study were obtained from the 2022 Ghana Demographic and Health Survey (GDHS) conducted between October 17, 2022 and January 14, 2023. A total weighted sample of 719 sexually active adolescent girls who reported having sexual partners was extracted from the women's data file. Data were analyzed with SPSS version 27, employing multilevel logistics regression modelling. Statistical significance was set at p < 0.05.

Results: The average age at sexual debut for adolescent girls aged 15-19 years in Ghana is 15.5 years. A little over half (51.6%) of adolescent girls reported having two or more lifetime sexual partners. Adolescent girls who initiated sex before reaching age 15 were more likely (aOR = 2.00; C.I 1.39-2.87) to have multiple partners compared to those who had their first sex before attaining age 20. After controlling for other factors, girls who had their sexual debut before age 15 had higher odds (aOR = 1.85; C.I:1.30-3.31) of engaging in multiple sexual partnerships. Girls living female headed households (aOR = 2.25; C.I:1.18-4.29] and consuming alcohol (aOR = 2.38; C.I 2.38-1.09-5.17) had higher odds of having multiple sexual partners.

Conclusion: The study findings show that early sexual debut, living in female headed household, and consuming alcohol are strong predictors of multiple sexual partnerships among adolescent girls in Ghana. It suggests the need for policies promoting delayed sexual debut and empowering adolescents to make informed decisions to improve sexual health outcomes.

Malaria remains a key health and economic problem, particularly in sub-Saharan Africa. The emergence of artemisinin drug resistance (ART-R) parasite strains poses a serious threat to the control and elimination of this scourge. This is because artemisinin-based combination therapies (ACTs) remain the first-line treatment in the majority of malaria-endemic regions in Sub-Saharan Africa. Certain single-nucleotide polymorphisms in the propeller domains of Plasmodium falciparum Kelch 13 protein (K13) have been associated with delayed parasite clearance in vivo and in vitro. These mutations serve as vital molecular markers for tracking the emergence and dispersion of resistance. Recently, there have been increasing reports of the emergence and spread of P. falciparum ART-R parasites in the Eastern Africa region. This necessitates continued surveillance to best inform mitigation efforts. This study investigated the presence of all reported mutations of K13 propeller domains in the parasite population in Busia County, Kenya, a known malaria-endemic region. Two hundred twenty-six participants with microscopically confirmed uncomplicated malaria were recruited for this study. They were treated with artemether-lumefantrine under observation for the first dose, and microscopic examination was repeated 1 day later after ensuring the participants had taken the second and third doses. P. falciparum DNA from all samples underwent targeted amplification of the K13 gene using a semi-nested PCR approach, followed by Sanger sequencing. The recently validated ART-R K13 mutation C469Y was identified in three samples. These three samples were among 63 samples with a low reduction in parasitemia on day 1, suggesting day 1 parasitemia reduction rate is a useful parameter to enrich the ART-R parasites for further analysis. Our findings highlight the need for continuous surveillance of ART-R in western Kenya and the region to determine the spread of ART-R and inform containment.

Background: Sub-Saharan Africa (sSA) continues to rank among the regions in the world with the highest rates of maternal mortality and the lowest rates of utilization of maternal health care. The risk of death for women in sSA is 268 times higher than that of women in high-income nations. Adequate antenatal care (ANC) services utilization is essential to the mother's and the baby's survival and well-being. This study aimed to identify both individual and community-level factors associated with adequate antenatal care services utilization in sSA.

Method: We used data from the most recent Health and Demographic Surveys (DHS), which were carried out between 2012 and 2022 in 33 sSA countries. A total of 240,792 women were included in this study. The two-level mixed-effects logistic regression model was used to identify the individual and community-level factors associated with the use of adequate ANC service.

Results: The pooled prevalence of adequate ANC service utilization in sSA was 55.48% (95% CI: 55.28-55.68). The study showed that secondary and above-educated women (AOR = 2.13, 95% CI 2.07-2.19, secondary and above-educated husbands (AOR = 1.55, 95% CI 1.51-1.60), rich women AOR = 1.26, 95% CI 1.24-1.29), women 35-49 years of age (AOR = 1.36, 95% CI 1.32-1.41) and distance to a health facility is not a big problem (AOR = 1.13; 95% CI 1.11-1.16) was significantly and positively correlated with the use of adequate ANC services. However, rural women (AOR = 0.80; 95% CI 0.78-0.82), not having mass media access (AOR = 0.74, 95% CI 0.72-0.75), 5 and above birth order (AOR = 0.73, 95% CI 0.68-0.78) were significantly and negatively correlated with the use of adequate ANC services. Additionally, the random effects model showed that variables at the community and individual levels were responsible for approximately 62.60% of the variation in the use of adequate ANC services.

Conclusion: The sSA countries had a low prevalence of adequate utilization of ANC with a significant variation among countries. Moreover, public health initiatives should focus on rural women, poor women, and uneducated women to enhance maternal health services utilization. Furthermore, policies and programs that address cluster variations in the utilization of adequate ANC services must be developed, and their implementation must be vigorously pursued.
