BACKGROUND AND OBJECTIVES
Non-Hodgkin Lymphoma (NHL) ranks 11th in cancer incidence and mortality in the Philippines with the combination chemotherapy composed of Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone (CHOP) being commonly used as treatment. However, the addition of Rituximab to CHOP (R-CHOP) has been shown to exhibit higher response rates and longer remissions, potentially improving quality of life. Currently, there is conflicting evidence on the cost-utility of CHOP versus R-CHOP. The study aimed to describe the patient- and country-specific factors, and treatment modalities used for NHL and systematically review cost-utility evidence of R-CHOP versus CHOP in adult NHL patients.
METHODSA systematic literature search of cost-utility studies on R-CHOP versus CHOP for NHL treatment was performed on eight databases: PubMed/MEDLINE, Scopus, Web of Science, EBSCOHost, Cochrane, York Research Database, Centre for Reviews and Dissemination Database, and HERDIN, where 607 studies were identified. Upon screening using an eligibility criteria, 10 studies were included and critically assessed using four appraisal tools: CHEERS, Drummond, Cooper, and ECOBIAS. These were performed independently by two authors with a third author assisting to help reach a consensus.
RESULTSAll studies from high-income countries (HICs) (n=8) and low-middle-income country (LMIC) (n=1) suggested that R-CHOP was more cost-effective for NHL treatment than CHOP in terms of utility outcomes. The study conducted in a low-income country (LIC) (n=1) suggested the opposite, favoring CHOP over R-CHOP. Methodological differences such as perspective, discount rate, willingness-to-pay (WTP), time horizon, and economic model were observed. Methodological limitations include completeness of data reported and credibility of sources used.
CONCLUSIONThe results of this review shall be interpreted with caution as those favoring R-CHOP over CHOP for NHL treatment in terms of cost-utility were concentrated in HICs. More economic evaluations from LICs, LMICs, and upper-middle income countries (UMICs) are needed for a robust conclusion. Additionally, establishing a universally recognized guideline for economic evaluations is essential to guide researchers effectively.

BACKGROUND AND OBJECTIVES
Staphylococcus aureus poses a significant public health threat globally, where both community and hospital-acquired infections are prevalent. The escalating antimicrobial resistance highlights the urgent need for alternative therapies. Hence, traditional medicine using plant extracts offers a potential avenue for novel antibacterial agents. This systematic review aimed to evaluate the existing literature on the antibacterial properties of Philippine plants against S. aureus to provide focus on drug development of a plant-derived antibacterial for this pathogen.
METHODSFollowing PRISMA guidelines, a comprehensive search was conducted in PubMed/Medline, SCOPUS, and Herdin databases. Inclusion criteria encompassed in-vitro studies evaluating the antibacterial activity of crude plant extracts sourced from Philippines plants against S. aureus. Data extraction and quality assessment were performed independently by two reviewers, with discrepancies resolved by the third and fourth reviewers.
RESULTSOf the 413 initial studies identified, nine (9) met the eligibility criteria. The highest zone of inhibition was demonstrated by Lippia micromera L. leaf essential oil at 26.3±1.5 mm, while moderate antibacterial activity was shown by essential oils from Alpinia elegans, Piper quinqueangulatum, and Alpinia cumingii at MIC values of 512 µg/mL, 512 µg/mL, and 1,024 µg/mL, respectively. Other Philippine plants showed a wide range of activity, with MIC values between 50 ?g/mL and 25 mg/mL, MBC values from 78 to 5000 ?g/mL, and ZOI ranging from 5 to 38 mm. However, the overall quality of evidence in these other studies are compromised by bias and incomplete reporting.
CONCLUSIONLeaf essential oils from Alpinia elegans, Piper quinqueangulatum, and Alpinia cumingii demonstrated moderate antibacterial activity against S. aureus. Additionally, the essential oils of Lippia micromera L., Plectranthus amboinicus Lour. Spreng, and Cymbopogon citratus exhibited antibacterial activity against both S. aureus and Methicillin-resistant S. aureus (MRSA) in disk diffusion assays. Majority of the studies gathered had high risk of bias according to the quality assessment criteria tool used in the study. Thus, this systematic review also emphasizes the need for improved methodological rigor on reported in-vitro antibacterial studies.

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.

BACKGROUND
Globally, cancer remains to be one of the leading causes of mortality and poses significant burden to patients and families. A growing body of evidence suggests that early palliative care results in more favorable patient and caregiver outcomes compared to standard oncology care alone.
OBJECTIVESThis study aims to determine the effects of early palliative care on caregivers of adult cancer patients in terms of quality of life, psychological distress, and satisfaction with care.
METHODSSystematic database searches in PubMed, Google Scholar, Cochrane library and Clinicaltrials.gov registry was conducted to select eligible studies for this review. Keywords, limit fields and Boolean operators were used for the search. Qualitative and quantitative analyses through the Review manager 5.4 software were done to compare quality of life, psychological distress, and satisfaction with care among caregivers given early palliative care vs. caregivers given standard oncology care.
CONCLUSIONThis review revealed inconclusive evidence on the benefits of early palliative care on caregiver outcomes when compared to standard care. We reviewed outcomes of early palliative care including quality of life, psychological distress, and satisfaction with care, but evidence remains unclear due to paucity of studies. Larger, high-caliber trials with more robust evidences, refinement of measurement tools catered to caregivers with higher sensitivity, and standardization of EPC protocol are needed to detect effect of EPC.

The Filipino Family Physician 2024;62(2):317-323
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.

Introduction:
There is an increasing number of publications on health literacy from Malaysia. We conducted a systematic review of Malaysian studies to determine the prevalence of limited general health literacy and the associated factors among Malaysian adults.
Materials and Methods:
We conducted a comprehensive search for Malaysian studies on health literacy using PubMed, Scopus and Google Scholar. Cross-sectional studies that measured general health literacy using specific rating scales among adults in Malaysia were retrieved for qualitative analysis. Quantitative synthesis of the prevalence of limited health literacy measured using two rating scales (Newest Vital Sign, NVS and various versions of European Health Literacy Survey, HLS) was performed using random effect model.
Results:
Twenty-five studies measuring general health literacy were retrieved for qualitative analysis; the majority were various versions of HLS and NVS. Pooled prevalence rates of limited health literacy were: HLS: 48.59%; NVS: 91.41%. Subgroup analysis of participant type revealed prevalence of limited health literacy measured using NVS was lower in clinical samples vs non-clinical samples (85.67% vs 94.70%). Moderator analysis revealed a small effect of ethnicity on prevalence of health literacy measured using HLS. Assessment of included studies showed very few of them had statistically significant associations between socio-demographic factors and limited health literacy.
Conclusion
Prevalence of limited health literacy in Malaysian adults was very high: almost one in two adults in HLS studies and nine out of ten adults in NVS studies. Socio-demographic factors associated with limited health literacy were inconsistent with other studies.

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.
