BACKGROUND:
Hospitalization in neonatal intensive care units (NICU) exposes preterm infants to adverse stimuli, including continuous 24-hour lighting. There is currently no standardized NICU layout advised for the best development of preterm neonates. This meta-analysis aimed to assess the impact of cycled light (CL) exposure on clinical outcomes in premature infants admitted to NICU as synthesized in previous studies.
MATERIALS AND METHODS:
This meta-analysis protocol was developed following the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) statement. A search was performed in PubMed/MEDLINE, EMBASE, Scopus, and Cochrane databases using the MeSH/key words: ―light exposure‖ AND pre-term AND cycled AND (RCT OR trials OR ―randomized controlled trial). The pooled Mean Difference with corresponding 95% CI was computed for weight gain, duration until start of enteral feeding, and duration of ICU stay using the Mantel–Haenszel random-effect model.
RESULTS:
Nine studies were included. The pooled mean difference showed that among preterm infants who had cycled light exposure, average daily weight gain (MD=6.24 grams, 95%CI=1.36 to 11.13, p=0.01) was significantly higher than those with continuous light exposure. The average time to start enteral feeding (MD=-3.84 days, 95%CI=-7.56 to -0.13, p=0.04) and average ICU stay (MD=-8.43 days, 95%CI=-12.54 to -4.31, p<0.0001) among neonates who had cycled light exposure were significantly shorter.
CONCLUSION
Benefits were seen in preterm infants when exposed to cycled light as opposed to continuous light. CL exposed infants showed a daily weight gain that was 6.24 grams higher, on average, and began enteral feeding nearly 4 days sooner. It led to a decrease in the duration of ICU stay by around 8 to 9 days on average. Further trials to determine the impact of cycled light exposure on morbidity and mortality among preterm neonates is recommended.

OBJECTIVE:
Attention Deficit Hyperactivity Disorder (ADHD) is a common mental disorder in children. It is unclear how nutrition and dietary components relate to ADHD. Some studies suggest that children with ADHD have lower serum levels of vitamin D than healthy controls. In the current study, the effects of Vitamin D supplementation on ADHD were reviewed and analyzed using available literature.
MATERIALS AND METHODS:
A meta-analysis and systematic review were performed. Children less than 18 years old diagnosed with ADHD given Vitamin D supplementation or placebo were included. A search was performed in PubMed/MEDLINE, EMBASE, Scopus, Cochrane, and Google Scholar databases from inception to August 2024 using the MeSH keywords: "Vitamin D" AND (ADHD OR Attention Deficit Hyperactivity Disorder) AND (children OR pediatric OR adolescents) AND randomized controlled trial. Standardized Mean Difference (SMD) was used as an effect measure and pooled using random effects meta-analysis.
RESULTS:
The pooled SMS showed significantly lower ADHD scores (SMD=-0.59, 95%CI=-1.06 to -0.11, p=0.01), lower inattentive scores (SMD=-0.61, 95%CI=-1.00 to -0.23, p=0.002), and lower hyperactivity scores (SMD=-0.64, 95%CI=-1.08 to -0.20, p=0.004) in children given Vitamin D supplementation. The adverse events reported were minor only and did not vary significantly between intervention and control groups.
CONCLUSION
Vitamin D treatment as an adjuvant to methylphenidate alleviated ADHD symptoms without significant adverse effects, correlating with enhanced vitamin D levels. Given the robust evidence and well-structured randomized controlled trials, we strongly advocate for the integration of vitamin D supplementation with ADHD treatment.

Acta Medica Philippina 2024;58(6):14-23
Background:
The number of individuals with mild cognitive impairment (MCI), or those people without dementia who are experiencing age-related cognitive decline, has increased in recent years. Conveniently, several interventions to delay cognitive decline exist, where cognitively stimulating activities (CSA) have been receiving too much attention. However, its beneficial effects have not been well established among older people with MCI due to conflicting findings.
Objectives:
This study aimed to assess and summarize the available evidence on the effects of CSA on the overall cognitive functioning of older people with MCI. Specifically, it sought to answer the PICO question, “In older people with MCI, does engagement in cognitively stimulating activities improve cognitive function?”
Methods:
A systematic review and meta-analysis of randomized controlled trials examining the effects of CSA on
older people with MCI were conducted. Three studies met the inclusion criteria from the 1,328 records from BioMed Central, CINAHL, Cochrane Library, Health Source: Nursing/Academic Edition, MEDLINE, and PubMed databases and 156 articles from WorldCat, DSpace Saint Louis University, and Google Scholar databases and catalogs. Effect size values were inspected using the random-effects model. Data were summarized as standardized mean difference (SMD) with corresponding 95% confidence intervals in the forest plot.
Results:
This meta-analysis which compared studies that employed similar methodologies, found that CSA has a significant, large effect in improving cognitive functioning among older people with MCI, evidenced by an SMD of 0.798 (95% CI = 0.510-1.085, p = 0.001). While its superiority over other interventions that improve cognitive function was not observed in this study, it was still found that using CSA was helpful in terms of its cost-effectiveness. Also, heterogeneity across studies was non-significant (Cochran’s Q = 0.151, df = 2, p = 0.927, I2 = 0.00%). These results mean that clinical heterogeneity was absent even though a diverse range of CSA was employed. Additionally, methodological diversity was not present since there were no variations in the study design and minimal variability in the risk of bias assessment.
Conclusion
Overall, it is acknowledged that CSA are effective and practical, inexpensive, non-pharmacologic cognitive training approaches to delay cognitive decline among older people with MCI. However, interpreting this study’s significant, large effect, and non-significant heterogeneity warrants caution.

Journal of the Philippine Dermatological Society 2024;33(Suppl 1):33-33
BACKGROUND
Pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are rare, chronic autoimmune blistering diseases primarily treated with systemic glucocorticoids. Long-term use of glucocorticoids can result in significant adverse effects, leading to the exploration of steroid-sparing adjuvants. This meta-analysis aimed to evaluate the efficacy and safety of glucocorticoids alone versus in combination with adjuvants for treating PV and PF.
OBJECTIVEThe main objective of this study was to compare the efficacy and safety of oral glucocorticoids alone versus with steroid-sparing adjuvants in treatment of PV and PF.
METHODSThis research was a systematic review and quantitative meta-analysis of randomized controlled trials (RCTs) that compared systemic glucocorticoids with or without steroid-sparing adjuvants in treating PV and PF. A total of 20 RCTs were included after meeting the inclusion criteria, comprising 1169 patients diagnosed with PV or PF. Primary outcomes were remission rates, while secondary outcomes included relapse rates, disease control, and the occurrence of adverse events.
RESULTSStudies involving rituximab and cyclophosphamide demonstrated significantly higher remission rates compared to other adjuvants or glucocorticoid monotherapy. Adverse events were common, particularly with high-dose glucocorticoids.
CONCLUSIONSThe meta-analysis found that rituximab and cyclophosphamide were superior steroid-sparing adjuvants in the treatment of PV and PF. Other adjuvants, such as azathioprine and mycophenolate mofetil, also showed efficacy but had a higher incidence of adverse events. Further studies were needed to optimize treatment protocols and reduce long-term complications.

BACKGROUND
Long-term administration of conventional acne medications implies the potential risk of increasing microbial resistance, and safety risks. Recent interest has grown in probiotics as a potential treatment and as an adjunct for acne vulgaris.
OBJECTIVETo conduct a systematic review of randomized controlled trials of oral probiotics in reducing the severity of acne vulgaris compared to placebo or conventional treatments.
METHODSPubMed, Cochrane Central Register of Controlled Trials, Embase, WHO ICTRP and ClinicalTrials.gov were searched for relevant studies, and randomized controlled trials of acne vulgaris treatment with probiotic therapy were included. Outcomes include decrease in total lesion count/percent change from baseline, improvement of severity scores, inflammation related indicators, and gene expression. Changes in outcomes were calculated by effect size or pooled odds ratio.
RESULTSA total of 2 RCTs involving 100 participants were included. Both studies show low risk on the risk bias criteria. The data of 2 RCTs reporting severity scores (AGSS and GAGS) supports that probiotics can improve their scores and thereby their condition. For inflammation-related indicators, only 1 RCT showed that probiotics can improve the IGF1 and FOXO1 gene expression in the skin. Regarding safety, only Eguren et al. reported adverse event. Their RCT showed that the incidence of adverse events was low and no serious adverse events.
CONCLUSIONIn conclusion, the probiotics investigated in both studies may be given as adjuvant treatment for acne vulgaris as they improve the clinical course of patients.

Systematic reviews and meta-analysis combine results and analysis of data from different primary studies (e.g. cross-sectional studies, case-control studies, cohort studies) conducted on similar or related research topics. They are secondary studies that guide clinical decision-making, delivery of care and policy development. This article aims to discuss how to conduct a systematic review and meta-analysis. The steps in conducting a systematic review and meta-analysis include: 1) Identify the purpose including formulating the research question and validating the purpose of the literature scan, 2) Formulate the objectives, 3) Literature search including selection of studies based on population, intervention, comparison and outcome, 4) Retrieval of full text articles, 5) Critical appraisal of articles, 6) Data extraction, 7) Data analysis and 8) Writing the final report. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) is a useful guide in conducting and write systematic review and meta-analysis. While ethics approval is not usually required for systematic review and meta-analysis, authors of such study should still observe good practices including avoiding plagiarism, maintaining transparency and ensuring data accuracy.

BACKGROUND
Chronic kidney disease (CKD) poses a global health threat with significant morbidity and mortality. Despite current therapies, there is a need for innovative interventions to slow CKD progression. Probiotic supplementation shows promise due to its positive effects on gastrointestinal health and inflammation. However, existing research is inconclusive, necessitating a meta-analysis to assess probiotics’ impact on CKD outcomes.
OBJECTIVETo evaluate the existing scientific literature among probiotic supplementation and the improvement in glomerular filtration rate (GFR) among chronic kidney disease (CKD) patients compared to placebo treatment.
METHODSA comprehensive search of electronic databases was conducted to identify relevant studies published up to 2023. Studies that meet the predefined eligibility criteria were included. Data extraction was performed, and methodological quality and risk of bias assessment was conducted for each study. Effect measures, such as mean differences or standardized mean differences, were used to quantify the association between probiotic supplementation and GFR improvement. The random-effects model was applied to estimate the overall effect size, and subgroup analyses were performed to explore potential sources of heterogeneity. Publication bias was assessed, and sensitivity analyses was conducted to evaluate the robustness of the findings.
RESULTSThe meta-analysis encompassed three randomized controlled trials (RCTs) conducted from 2017 to 2023, involving 121 chronic kidney disease (CKD) patients. The analysis focused on the impact of probiotic supplementation on CKD, examining Glomerular Filtration Rate (GFR), Blood Urea Nitrogen (BUN), and Urine Protein Creatinine Ratio (UPCR). While no significant distinctions were found in GFR and BUN changes between probiotics and placebos, there was a statistically significant reduction in UPCR associated with probiotic supplementation in one study. Notably, considerable heterogeneity in GFR and significant heterogeneity in UPCR reduction were observed among the trials. Sensitivity analysis, excluding studies with small sample sizes or high bias risk, remained consistent with overall findings.
CONCLUSIONThe meta-analysis indicated no significant impact of probiotic supplementation on GFR and BUN, but there was a notable reduction in Urine UPCR. The observed heterogeneity among the studies calls for cautious interpretation due to variations in study designs, patient populations, and probiotic formulations. While the results suggest a potential role for probiotics in reducing proteinuria in chronic kidney disease (CKD) patients, the need for further research with larger sample sizes and standardized methodologies is emphasized to establish definitive conclusions.

Introduction:
Chinese medicine (CM) external therapy is commonly used to treat rheumatoid arthritis (RA) in combination with conventional drug. This study aims to provide a comprehensive synthesis on the efficacy of CM external therapy combined with conventional drug treatment in RA.
Methods:
Randomised controlled trials (RCTs) experimenting the efficacy of CM external therapy (acupuncture, moxibustion and CM fumigation) combined with conventional drug in comparison with conventional drug only in RA patients were collected from PubMed, Medline, Cochrane Central of Controlled Trials (CENTRAL), ClinicalTrials.gov, China National Knowledge Infrastructure (CNKI), and Wanfang databases. Quality was assessed using the Cochrane Risk of Bias Tool. The outcome measures which include Disease Activity Score-28 (DAS28), Visual Analogue Scale (VAS), Swollen Joint Count (SJC), Tumour Necrosis Factor (TNF-α), serum levels of C-reactive Protein (CRP) and Erythrocyte Sedimentation Rate (ESR) were analysed using Review Manager 5.4.1 and GRADEpro GDT online software.
Results:
Fifty RCTs fulfilling the criteria were included. Although some level of efficacy was statistically noted on the use of CM external therapies, their certainty levels are mixed, ranging only in between moderate and low.
Conclusions
Mixed levels of certainty has hindered the drawing of conclusion. The addition of CM external therapies to conventional drug treatment may provide some benefits in RA. Further clinical trials with considerations in minimising the risk of bias are recommended to provide more high-quality evidence in the effect of CM external therapies as a complementary treatment in RA.

OBJECTIVE:
To assess the methodological quality, report quality and evidence quality of the Meta-analysis and systematic reviews of acupuncture and moxibustion for children with cerebral palsy, aiming to provide decision-making basis for clinical treatment.
METHODS:
The systematic reviews and Meta-analysis of acupuncture and moxibustion for children with cerebral palsy were searched in CNKI, Wanfang, VIP, SinoMed, Cochrane Library, PubMed and EMbase. The retrieval time was from the database establishment to June 30th, 2022. AMSTAR 2 (a measurement tool to assess systematic reviews) was used to evaluate the methodological quality, and PRISMA (preferred reporting items for systematic reviews and Meta-analyses) was used to evaluate the report quality, and GRADE was used to evaluate the quality of evidence.
RESULTS:
A total of 14 systematic reviews were included, including 37 primary outcome indexes. According to AMSTAR 2 evaluation results, there were 4 low quality studies, 10 very low quality studies, and low scores on items 2, 4, 7, 10 and 16. PRISMA scores ranged from 15 to 25, and the main reporting problems reflected in structured abstracts, program and registration, retrieval, and funding sources, etc. According to the GRADE classification results, there were 3 high quality evidences, 7 medium quality evidences, 10 low quality evidences and 17 very low quality evidences. The main downgrading factors were limitations, imprecision and publication bias.
CONCLUSION
Acupuncture and moxibustion has a certain effect for cerebral palsy in children, but the quality of methodology, reporting and evidence in the included literature is poor, and the comparison of curative effect between different acupuncture and moxibustion methods is unclear.
