Therapeutic Role of Zinc Supplementation in Children Hospitalized with Pneumonia

Less than one in five teenage women in Ethiopia know about emergency contraception

Background

Teenage women's fertility health faces significant challenges from unintended pregnancies and unsafe abortions. Using an emergency contraception within a defined time period could prevent unintended pregnancy and its damaging consequences, like unintended childbirth and unsafe abortion. Despite it being an appropriate contraception, the knowledge of teenage women about emergency contraception is lower among women in developing countries. Therefore, this study aimed to examine the magnitude of emergency contraception knowledge and its associated factors among teenage women in Ethiopia.

Methods

Data for this study was obtained from the recent Demographic and Health Surveys. A total weighted sample of 3,381 teenage reproductive women were included. The significant associated factors with emergency contraception knowledge among teenage reproductive women were determined by fitting a multilevel mixed-effect binary logistic regression model. Finally, Adjusted Odds Ratio (AOR) with a 95% confidence interval and a P value of less than 0.05 was used to declare statistical significance.

Results

In Ethiopia, the magnitude of teenage women who knew about emergency contraception was 19.47% (95%CI: 18.17, 20.84). Age 17 years (AOR = 1.76, 95%CI, 1.24, 2.48) and age 19 years (AOR = 2.18, 95%CI, 1.47, 3.22), primary education level (AOR = 2.76, 95%CI, 1.60, 4.76), secondary and above educational level (AOR = 4.70, 95%CI, 2.62, 8.44), being protestant followers (AOR = 0.63, 95%CI, 0.45, 0.87), being muslim followers (AOR = 0.68, 95%CI, 0.49, 0.93), media exposure (AOR = 3.36, 95%CI, 2.59, 4.34), rural residence (AOR = 0.45; 95%CI: 0.22, 0.86), and high community level education (AOR = 140, 95%CI: 1.32, 2.00) were factors significantly associated with knowledge of emergency contraception among teenage women.

Conclusions

This finding concluded that less than one in five teenage women knew about emergency contraception in Ethiopia. The knowledge of emergency contraception among teenage women in Ethiopia was substantially associated with women's age, education level, religion, media exposure, residency and community-level education. Hence, there is a need to implement comprehensive awareness programs and promotion of emergency contraception as a way of curbing cases of unintended pregnancies among teenage women. Government and non-governmental organizations should design targeted educational initiatives and media campaigns to improve emergency contraception knowledge among young teenagers, women with lower educational backgrounds, and rural teenagers.

Zinc Deficiency and the Severity of Pneumonia in Vietnamese Children: A Hospital-Based Study

Background Pneumonia is a critical global health concern that often results in severe complications and fatalities, especially among young children. Zinc plays a crucial role in immune function and maintaining respiratory epithelial integrity. Despite its importance, data on the prevalence of zinc deficiency and its impact on pneumonia severity in Vietnamese children are limited. Objectives This study aimed to investigate the prevalence of zinc deficiency and its association with pneumonia severity in Vietnamese children under five years old. The findings could significantly contribute to our understanding of the role of zinc in pneumonia severity, guiding future public health interventions, nutritional policies, and clinical practices to prevent zinc deficiency and reduce pneumonia morbidity and mortality in children. Methods An analytical cross-sectional study was conducted at a major pediatric center in Southwestern Vietnam from December 2022 to February 2024, involving 222 children aged 2 to 59 months diagnosed with pneumonia. Clinical assessments and laboratory measurements, including serum zinc levels, were performed. Statistical analyses were conducted to compare clinical characteristics and outcomes between zinc-deficient and non-deficient groups. Multivariable logistic regression was used to assess the association between zinc deficiency and pneumonia severity, with statistical significance set at p<0.05. Results The prevalence of zinc deficiency among children with pneumonia was 74.3%. Zinc-deficient children showed a significantly higher proportion of severe pneumonia (57.6% vs. 8.8%, p<0.001), as well as a higher proportion of high fever, poor feeding, vomiting, and respiratory distress compared to non-deficient children (p<0.001). Multivariable logistic regression identified zinc deficiency as an independent predictor of severe pneumonia (aOR=13.1, 95% CI: 4.7-36.8, p<0.001). Conclusion Zinc deficiency was prevalent among Vietnamese children with pneumonia and was associated with an increased risk of severe pneumonia.

Review of the role of additional treatments including oseltamivir, oral steroids, macrolides, and vitamin supplementation for children with severe pneumonia in low- and middle-income countries

Background

Pneumonia is a major cause of death in children aged under five years. As children with severe pneumonia have the highest risk of morbidity and mortality, previous studies have evaluated the additional benefit of adjunctive treatments such as oseltamivir, oral steroids, macrolides, and vitamin supplementation that can be added to standard antibiotic management to improve clinical outcomes. The study reviewed the evidence for the role of these additional treatments for children with severe pneumonia in low- and middle-income countries (LMICs).

Methods

Four electronic databases were searched for English-language articles between 2000 to 2020. Systematic reviews (SRs) with meta-analyses, comparative cohort studies, and randomised controlled trials (RCTs) from LMICs that reported clinical outcomes for children with severe pneumonia aged between one month to 9 years who received adjunct treatment in addition to standard care were included. Risk of bias of included SRs was assessed using AMSTAR 2, and of individual studies using the Effective Public Health Practice Project (EPHPP) quality assessment tool for quantitative studies.

Results

Overall, the search identified 2147 articles, 32 of which were eligible, including 7 SRs and 25 RCTs. These studies evaluated zinc (4 SRs, 17 RCTs), Vitamin D (1 SR, 4 RCTs), Vitamin A (3 SRs, 1 RCT), Vitamin C (1 SR, 2 RCTs) and micronutrients (1 RCT). Most studies reported clinical outcomes of time to improvement, length of stay, and treatment failure (including mortality). No studies of oseltamivir, steroids, or macrolides fulfilling the inclusion criteria were identified. For zinc, pooled analyses from SRs showed no evidence of benefit. Similarly, a Cochrane review and one RCT found that Vitamin A did not improve clinical outcomes. For Vitamin D, an RCT evaluating a single high dose of 100 000 international units (IU) of vitamin D found a reduction in time to improvement, with 38%-40% documented vitamin D deficiency at baseline. However, two other studies of 1000 IU daily did not show any effect, but vitamin D status was not measured. For vitamin C, two studies found a reduction in time to symptom resolution in those with severe disease, with one reporting a shorter length of hospital stay. However, both studies were of weak quality. Most studies excluded malnourished children, and studies which included these children did not report specifically on the effect of micronutrients.

Conclusions

This review found that adjunctive zinc and vitamin A, in addition to standard care, does not improve clinical outcomes in children with severe pneumonia in LMICs (strong evidence). However, a reduction in time to symptom resolution was reported with high dose vitamin D supplementation in children with documented vitamin D deficiency (strong evidence from one study) and vitamin C (weak evidence), although further research is needed, especially in underweight children.
