Meta-Analysis
BACKGROUND
Children living with HIV/AIDS are particularly vulnerable to under-nutrition. Under-nutrition associated with HIV/AIDS infection increases the rate of morbidity and mortality in children. To reaffirm a future objective, there needs to be evidence regarding the current national burden of under-nutrition and related factors among children infected with HIV. Hence, the objective of this systematic review and meta-analysis was to estimate the pooled prevalence of under-nutrition, and the pooled effect sizes of associated factors among HIV-infected children in Ethiopia.
METHODS
We searched Ethiopian universities' online libraries, Google, Google Scholar, PubMed, CINAHL, Cochrane Library, and Scopus to find the primary studies for this review. Publication bias was checked through Egger's regression test. Heterogeneity among the included studies was assessed using the I2 test. The data were extracted using Microsoft Excel and exported to STATA Version 14 statistical software. A random effect meta-analysis model was performed to estimate the pooled prevalence of Under-nutrition.
RESULTS
After reviewing 1449 primary studies, 16 articles met the inclusion criteria and were included in the final meta-analysis. The estimated pooled prevalence of stunting, underweight, and wasting among children living with HIV/AIDS was 32.98% (95% CI: 22.47, 43.50), 29.76% (95% CI: 21.87, 37.66), and 21.16% (95% CI: 14.96, 27.35) respectively.
CONCLUSIONS
This study showed that under-nutrition among HIV-infected children in Ethiopia was significantly high. Under-nutrition is more common among HIV-infected children with opportunistic infections, child feeding problems, do not adhere to dietary recommendations, and have diarrhea. The national policies and strategies for ART service- provider centers should maximize their emphasis on reducing under-nutrition among HIV-infected children. Based on this finding, we recommend HIV intervention programs to address nutritional assessment and interventions for HIV-infected children.

Otology & Neurotology : Official... Jun 2024To determine the cost-effectiveness or cost-utility of cochlear implants (CI) in adults with severe to profound bilateral hearing loss.
OBJECTIVE
To determine the cost-effectiveness or cost-utility of cochlear implants (CI) in adults with severe to profound bilateral hearing loss.
DATABASES REVIEWED
PubMed (Medline), The Cochrane Library, Embase via Elsevier, EBSCOhost CINAHL, and Scopus.
METHODS
The study included adult participants with severe to profound bilateral neurosensory hearing loss. The analysis encompassed quality of life improvements, costs, cost-effectiveness, cost-utility, cost-benefit, quality-adjusted life year (QALY), incremental cost-effectiveness ratio (ICER), and incremental cost-utility ratio (ICUR). Systematic reviews, meta-analyses, case series, and prospective or retrospective cohort studies published in English between 2010 and 2023 were retrieved. Exclusion criteria included incomplete studies, abstracts, clinical cases, editorials, letters, studies involving pediatric populations, single-side deafness, methodology research, noneconomic aspects of CI, mixed child and adult data, and studies published before 2010. The risk of bias was assessed following the criteria outlined in Appendix I of the economic evaluation's quality assessment as per the NICE Guideline Development Method.
RESULTS
Ten articles met the criteria and were included in the qualitative synthesis. One study conducted a prospective cost-utility analyses, one carried out a cost-benefit analyses, one was a randomized controlled clinical trial focusing on cost-utility, and another was a clinical trial addressing cost-effectiveness. Six studies employed Markov models, and one study utilized uniquely the Monte Carlo method. None quantified the economic impact of improved hearing on cognitive function.
CONCLUSIONS
The heterogeneity of sources impacted data quality. Unilateral and sequential bilateral CI appeared to be cost-effective when compared with bilateral hearing aids or nontechnological support. When properly indicated, simultaneous bilateral CIs are cost-effective compared to no interventions and to unilateral cochlear implantation through differential discounting or variations from the base cases, especially with a life expectancy of 5-10 years or longer.

Resuscitation Plus Sep 2024To compare the effectiveness of cognitive aid use during resuscitation with no use of cognitive aids on cardiopulmonary resuscitation quality and performance. (Review)
Review
OBJECTIVES
To compare the effectiveness of cognitive aid use during resuscitation with no use of cognitive aids on cardiopulmonary resuscitation quality and performance.
METHODS
This systematic review followed the PICOST format. All randomised controlled trials and non-randomised studies evaluating cognitive aid use during (simulated) resuscitation were included in any setting. Unpublished studies were excluded. We did not include studies that reported cognitive aid use during training for resuscitation alone. Medline, Embase and Cochrane databases were searched from inception until July 2019 (updated August 2022, November 2023, and 23 April 2024). We did not search trial registries. Title and abstract screening, full-text screening, data extraction, risk of bias assessment (using RoB2 and ROBINS-I), and certainty of evidence (using GRADE) were performed by two researchers. PRISMA reporting standards were followed, and registration (PROSPERO CRD42020159162, version 19 July 2022) was performed. No funding has been obtained.
RESULTS
The literature search identified 5029 citations. After removing 512 duplicates, reviewing the titles and abstracts of the remaining articles yielded 103 articles for full-text review. Hand-searching identified 3 more studies for full-text review. Of these, 29 studies were included in the final analysis. No clinical studies involving patients were identified. The review was limited to indirect evidence from simulation studies only. The results are presented in five different populations: healthcare professionals managing simulated resuscitations in neonates, children, adult advanced life support, and other emergencies; as well as lay providers managing resuscitations. Main outcomes were adherence to protocol or process, adherence to protocol or process assessed by performance score, CPR performance and retention, and feasibility of chatbot guidance. The risk of bias assessment ranged from low to high. Studies in neonatal, paediatric and adult life support delivered by healthcare professionals showed benefits of using cognitive aids, however, some studies evaluating resuscitations by lay providers reported undesirable effects. The performance of a -analysis was not possible due to significant methodological heterogeneity. The certainty of evidence was rated as moderate to very low due to serious indirectness, (very) serious risk of bias, serious inconsistency and (very) serious imprecision.
CONCLUSION
Because of the very low certainty evidence from simulation studies, we suggest that cognitive aids should be used by healthcare professionals during resuscitation. In contrast, we do not suggest use of cognitive aids for lay providers, based on low certainty evidence.

Review
For people at risk of HIV infection, pre-exposure prophylaxis (PrEP) can reduce the risk of infection in anticipation of exposure to HIV. The effectiveness of PrEP relies upon a user's adherence to their PrEP regimen. We sought to assess the effect of PrEP adherence interventions compared to usual care or another intervention for people at risk of HIV. We searched electronic databases from 2010 onwards for randomized controlled trials (RCTs) involving persons at risk of HIV randomized to an adherence promoting intervention vs usual care or another intervention. We used network meta-analyses to compare PrEP adherence for all participant populations. Certainty of evidence was assessed using Confidence in Network Meta-Analysis (CINeMA). 21 trials (N = 4917) were included in qualitative analysis (19 in network meta-analyses (N = 4101)). HIV self-testing interventions with adherence feedback elements improved adherence compared to usual care (risk ratio (RR): 1.83, 95%CI 1.19, 2.82). In contrast, HIV self-testing alone was inferior to HIV self-testing with adherence feedback (RR: 0.58, 95%CI 0.37-0.92). Reminders alone also were inferior to HIV self-testing with adherence feedback on adherence (RR: 0.53, 95%CI 0.34-0.84) and had similar effects on adherence as usual care (RR: 0.98, 95%CI: 0.86-1.11). Interventions with only one component were inferior for adherence than those with two components (RR: 0.74, 95%CI 0.62-0.88) and those with three components (RR: 0.78, 95%CI 0.65-0.93). The certainty of evidence was moderate for HIV self-testing plus adherence feedback and interventions with two or three components. When designing future PrEP adherence interventions, we recommend strategies with more than one but no more than three components.

Meta-Analysis
IMPORTANCE
Large-scale estimates of bronchopulmonary dysplasia (BPD) are warranted for adequate prevention and treatment. However, systematic approaches to ascertain rates of BPD are lacking.
OBJECTIVE
To conduct a systematic review and meta-analysis to assess the prevalence of BPD in very low birth weight (≤ 1,500 g) or very low gestational age (< 32 weeks) neonates.
DATA SOURCES
A search of MEDLINE from January 1990 until September 2019 using search terms related to BPD and prevalence was performed.
STUDY SELECTION
Randomized controlled trials and observational studies evaluating rates of BPD in very low birth weight or very low gestational age infants were eligible. Included studies defined BPD as positive pressure ventilation or oxygen requirement at 28 days (BPD28) or at 36 weeks postmenstrual age (BPD36).
DATA EXTRACTION AND SYNTHESIS
Two reviewers independently conducted all stages of the review. Random-effects meta-analysis was used to calculate the pooled prevalence. Subgroup analyses included gestational age group, birth weight group, setting, study period, continent, and gross domestic product. Sensitivity analyses were performed to reduce study heterogeneity.
MAIN OUTCOMES AND MEASURES
Prevalence of BPD defined as BPD28, BPD36, and by subgroups.
RESULTS
A total of 105 articles or databases and 780,936 patients were included in this review. The pooled prevalence was 35% (95% CI, 28-42%) for BPD28 (n = 26 datasets, 132,247 neonates), and 21% (95% CI, 19-24%) for BPD36 (n = 70 studies, 672,769 neonates). In subgroup meta-analyses, birth weight category, gestational age category, and continent were strong drivers of the pooled prevalence of BPD.
CONCLUSIONS AND RELEVANCE
This study provides a global estimation of BPD prevalence in very low birth weight/low gestation neonates.

Review
Advances in human immunodeficiency virus (HIV) treatment, including combination antiretroviral therapy (cART), have transformed HIV into a chronic condition. Kidney diseases cause morbidity and mortality in patients living with HIV (PLWH), though cART has permitted kidney transplants with acceptable post-transplant graft and patient survival. Risk of allograft rejection remains high, which may be related to interactions between cART, specifically protease inhibitors (PI), and immunosuppressants prescribed post-transplant. This systematic review evaluates renal transplant outcomes in PLWH treated with PI- vs non-PI-based cART. A search strategy was generated with terms related to renal transplant, HIV, and cART and run on PubMed, Embase, Scopus, and Cochrane. Studies were evaluated using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines on Covidence by two reviewers and then evaluated for bias. Of 803 studies, 9 were included. Included papers were prospective or retrospective cohort studies or chart reviews of adult patients. Outcome measures included acute graft rejection, graft survival, and patient survival. One study had significant results demonstrating that PI-based therapy was correlated with increased graft rejection rates. Two studies demonstrated significant graft survival benefit to non-PI-based therapy, while one demonstrated significant benefit to PI-based therapy. Two studies found significant patient survival benefit to non-PI-based therapy. For each outcome measure, remaining data suggested improved outcomes with non-PI-based therapies without achieving statistical significance. The results demonstrate superior outcomes in PLWH taking non-PI-based cART, though the paucity of significant results suggests that PLWH who require PI-based cART for virological control may continue their regimen safely post-kidney transplant.

BACKGROUND
Undernutrition is the leading cause of mortality among children infected with HIV particularly in resource-deprived settings. Despite several studies were disclosed the effect of undernutrition on mortality of children living with HIV in Ethiopia, the findings were fragmented and inconclusive. Therefore, this review aimed to determine the pooled effects of undernutrition on mortality of children infected with HIV in Ethiopia.
METHODS
The search were performed using international online electronic data bases (MEDLINE/though PubMed, Google scholar, Hinari, Scopus and open Google). The review included only retrospective/prospective cohort studies reporting the effects of undernutrition on mortality of children infected with HIV. Heterogeneity between included studies was assessed using Cochrane Q-test and the I statistics. Sub-group analysis was done by study regions, sample size and publication year.
RESULTS
A total of 1345 articles were identified from databases. Among these, 14 studies met the inclusion criteria and included in the study. Meta-analysis of 4 studies revealed that stunting has a significant effect on mortality of children infected with HIV (AHR: 3.36; 95 % CI: 2.95-3.77). Of 14 included studies, 6 articles indicated that wasting has a significant effect on mortality in children infected with HIV (AHR: 3.93; 95 % CI: 2.56-5.30) as compared to their counterparts. Furthermore, the pooled effect of 8 studies showed that underweight has 3.4 times hazard of death among children who lived with HIV as compared to well-nourished children.
CONCLUSION
This review revealed that undernutrition has deleterious effect on mortality of children infected with HIV/AIDS by disease progression and prone the children to serious opportunistic infections. From the study, the authors recommended that nutritional status of children on antiretroviral therapy need to be evaluated regularly.

Review
Paediatric percutaneous bone anchored hearing aid implant failures: Comparing the experience of a tertiary centre with a systematic review of the literature and meta-analysis.
BACKGROUND
Despite the proven audiological benefits of Percutaneous Bone Anchored Hearing Aids (BAHAs) in paediatric patients with conductive or mixed hearing loss, their adoption has been limited due to concerns over implant failure and associated complications. This paper conducts a systematic review and meta-analysis to assess the prevalence of implant failure in paediatric populations, combined with a case series from our tertiary referral centre.
METHODS
A comprehensive literature search identified 562 articles, from which 34 were included in the review, covering 1599 implants in 1285 patients. Our retrospective case series included consecutive patients from our tertiary referral centre who underwent percutaneous BAHA implantation from 2003-2019.
RESULTS
Meta-analysis revealed an overall implant failure rate of 11%, predominantly attributed to traumatic extrusion. Our retrospective case series comprised 104 implantations in 76 patients, with a 4.8% failure rate.
DISCUSSION
Factors contributing to the lower-than-expected failure rates in the case series likely included consistent use of 4 mm fixtures from a single manufacturer and older age at implantation. The study underscores the need for standardised reporting formats in bone conduction implants research, given the systematic review's limitations in study design heterogeneity, especially with the expected rise in the adoption of novel active devices.

Meta-Analysis
OBJECTIVE
To assess the effects of COVID-19 vaccines in women before or during pregnancy on SARS-CoV-2 infection-related, pregnancy, offspring and reactogenicity outcomes.
DESIGN
Systematic review and meta-analysis.
DATA SOURCES
Major databases between December 2019 and January 2023.
STUDY SELECTION
Nine pairs of reviewers contributed to study selection. We included test-negative designs, comparative cohorts and randomised trials on effects of COVID-19 vaccines on infection-related and pregnancy outcomes. Non-comparative cohort studies reporting reactogenicity outcomes were also included.
QUALITY ASSESSMENT, DATA EXTRACTION AND ANALYSIS
Two reviewers independently assessed study quality and extracted data. We undertook random-effects meta-analysis and reported findings as HRs, risk ratios (RRs), ORs or rates with 95% CIs.
RESULTS
Sixty-seven studies (1 813 947 women) were included. Overall, in test-negative design studies, pregnant women fully vaccinated with any COVID-19 vaccine had 61% reduced odds of SARS-CoV-2 infection during pregnancy (OR 0.39, 95% CI 0.21 to 0.75; 4 studies, 23 927 women; I=87.2%) and 94% reduced odds of hospital admission (OR 0.06, 95% CI 0.01 to 0.71; 2 studies, 868 women; I=92%). In adjusted cohort studies, the risk of hypertensive disorders in pregnancy was reduced by 12% (RR 0.88, 95% CI 0.82 to 0.92; 2 studies; 115 085 women), while caesarean section was reduced by 9% (OR 0.91, 95% CI 0.85 to 0.98; 6 studies; 30 192 women). We observed an 8% reduction in the risk of neonatal intensive care unit admission (RR 0.92, 95% CI 0.87 to 0.97; 2 studies; 54 569 women) in babies born to vaccinated versus not vaccinated women. In general, vaccination during pregnancy was not associated with increased risk of adverse pregnancy or perinatal outcomes. Pain at the injection site was the most common side effect reported (77%, 95% CI 52% to 94%; 11 studies; 27 195 women).
CONCLUSION
COVID-19 vaccines are effective in preventing SARS-CoV-2 infection and related complications in pregnant women.

Meta-Analysis Review
OBJECTIVE
The bone conduction implant (BCI) 602 is a new transcutaneous BCI with smaller dimensions. However, limited patient numbers restrict the statistical power and generalizability of the current studies. The present systematic review and meta-analysis summarize early audiological and medical outcomes of adult and pediatric patients implanted with the BCI 602 due to mixed or conductive hearing loss.
DATA SOURCE
Following the Preferred Reporting items for Systematic Reviews and Meta-analyses guidelines, 108 studies were reviewed, and 6 (5.6%) were included in the meta-analysis.
REVIEW METHOD
The data on study and patient characteristics, surgical outcomes, and audiological test results were extracted from each article. Meta-analysis employed the fixed-effect and random-effects models to analyze the mean differences (MDs) between pre- and postoperative performances.
RESULTS
In total, 116 patients were evaluated, including 64 (55%) adult and 52 (45%) pediatric patients. No intraoperative adverse events were reported, while postoperative complications were reported in 2 (3.1%) adult and 2 (3.8%) pediatric patients. Studies consistently showed significant improvements in audiological outcomes, quality of life, and sound localization in the aided condition. In the meta-analysis, we observed a significant difference in the unaided compared to the aided condition in sound field thresholds (n = 112; MD, -27.05 dB; P < 0.01), signal-to-noise ratio (n = 96; MD, -6.35 dB; P < 0.01), and word recognition scores (n = 96; MD, 68.89%; P < 0.01).
CONCLUSION
The implantation of the BCI 602 was associated with minimal surgical complications and excellent audiological outcomes for both the pediatric and the adult cohort. Therefore, our analysis indicates a high level of safety and reliability. Further research should focus on direct comparisons with other BCIs and long-term functional outcomes.
