At present, there is insufficient evidence to support the use of BCG vaccine as prophylaxis for COVID-19. Bacillus Calmette Guerin (BCG) vaccine is an attenuated microorganism derived from bovine tubercle bacillus and is being given to prevent severe tuberculosis. BCG vaccination may enhance production of antibodies and pro-inflammatory cytokines such as interleukin (IL)-1β and tumor necrosis factor (TNF). BCG may lead to increased CD4 and CD8 T-cell activity on subsequent viral infection. Ecological studies on the effect of BCG vaccination policy on COVID-19 outcomes have conflicting results and are prone to bias from confounders. There is insufficient evidence on the efficacy and safety of BCG vaccine for COVID-19 prophylaxis. Thirteen clinical trials are ongoing among high-risk groups (healthcare workers, elderly, police officers) to evaluate the efficacy and safety of BCG vaccine in preventing COVID-19 and its severe symptoms. WHO does not recommend the use of BCG vaccine as prophylaxis against COVID-19. Adverse events of BCG vaccine range from mild local cutaneous reactions to systemic adverse events such as abscess, lymphadenopathy and osteomyelitis.

OBJECTIVE

Dengue remains a critical public health concern in the Philippines. Late consultation and delayed presentation of dengue patients to hospitals constantly challenge doctors. This study aimed to identify factors contributing to late consultation of dengue patients.

METHODOLOGY

This analytic, cross-sectional study examined patient, parental, socioeconomic, cultural, and health system factors influencing delayed consultation among parents of patients 0 – 18 years at Batangas Medical Center and Lipa Medix Medical Center. A total of 668 parents were enrolled. Descriptive statistics and frequency tables summarized the key characteristics. Test of proportions assessed differences between groups. Univariate logistic regression screened possible predictors, followed by multiple logistic regression to identify significant factors.

RESULTS

Univariate analysis identified significant predictors of late consultation, including older patient age(p=0.002), residence >50 km from the hospital (p 50 km from the hospital were 2.7 times more likely to consult late (p=0.01).

CONCLUSION

Delayed consultation was influenced by the patient age, hospital type, geographic distance from the hospital, maternal marital status, and cultural beliefs in home remedies and faith healing. Strategies to improve early consultation should consider these factors.

Background: Preterm birth is an important health concern in countries with limited resources and healthcare access. Topical therapy may be effective for improving outcomes in preterm neonates whose skin barriers are compromised due to immaturity. Objectives: To systematically review the topical VCO's effects in preterm infants on infection, mortality, and dermal maturity. Methodology: Systematic review and meta-analysis of RCTs of topical VCO in preterm infants were conducted. Databases included PubMed, Google Scholar, Clinical trials.gov, Trip, Cochrane Library, and HERDIN. The risk of bias was assessed by two authors independently. RR with 95% CI was used for the pooled estimate of dichotomous outcomes including infection prevention, mortality reduction, and skin irritation. Mean differences with 95% CI were used for the pooled estimate of weight loss and NSCS. Results: Of 110 records identified, 3 RCTs with 2440 patients were included. Prevention of infection had a trend toward VCO (RR = 0.90, [95% CI: 0.64, 1.27] while the results for mortality reduction were inconclusive (RR = 0.45, [95% CI: 0.06, 3.38]. NSC scores showed a beneficial trend toward VCO (RR = -0.03, [95% CI: -0.16, 0.09]. Both secondary outcomes of skin irritation and weight loss had inconclusive results. Conclusions This review showed the lack of evidence of the effectiveness of topical VCO in improving various outcomes in premature infants. The effects on infection prevention and dermal maturation were favorable. However, its effects on preventing mortality, skin irritation, and weight loss were inconclusive.
