Pregnancy is a critical period in every woman's life. The health of both the mother and her unborn child is at stake, with poor access to needed prenatal care services. Obtaining prenatal care is affected by the pregnancy literacy of the expectant mother. However, the assessment tool for health literacy among Filipino pregnant women is limited. This paper aimed to examine existing maternal health literacy instruments. Hopefully, an adopted tool can be found for assessing prenatal health literacy. After examining existing maternal health literacy tools, 18 questions were suggested that can be further modified before they are used for Filipino pregnant women to assess their prenatal health literacy.

The Philippines has an increasingly aging population thereby increasing the demand for healthcare and support from families. Studies showed that the family is the main caregiver of elderly parents/adults as dictated by the Filipino culture of filial piety and respectful behavior towards older people. However, this caring culture is now slowly declining, and Filipino older adults also experience abuse, exploitation, and other forms of neglect from their families. This special article described that the declining caring culture was due to deteriorating family values and societal influences brought about by modernization. This paper also highlights the crucial role of the family and the community in inculcating the preservation of this valued caring Filipino culture, especially among the youth. In cases where senior citizens are being abused and neglected by their families, the state steps in to safeguard the welfare and protection of Filipino senior citizens. Enacted and promulgated laws ensure social justice and protection of human dignity among Filipino older adults as well as the provision of socioeconomic and health needs. In conclusion, the preservation of a caring culture through educating the youth coupled with the implementation of enacted and promulgated laws of the country ensures the quality of aging life among Filipino older adults.

Background and aim:Hepatic ischemia-reperfusion injury(IRI)is a significant challenge in liver trans-plantation,trauma,hypovolemic shock,and hepatectomy,with limited effective interventions available.This study aimed to investigate the role of leukocyte cell-derived chemotaxin 2(LECT2)in hepatic IRI and assess the therapeutic potential of Lect2-short hairpin RNA(shRNA)delivered through adeno-associated virus(AAV)vectors. Materials and methods:This study analyzed human liver and serum samples from five patients under-going the Pringle maneuver.Lect2-knockout and C57BL/6J mice were used.Hepatic IRI was induced by clamping the hepatic pedicle.Treatments included recombinant human LECT2(rLECT2)and AAV-Lect2-shRNA.LECT2 expression levels and serum biomarkers including alanine aminotransferase(ALT),aspartate aminotransferase(AST),creatinine,and blood urea nitrogen(BUN)were measured.Histological analysis of liver necrosis and quantitative reverse-transcription polymerase chain reaction were performed. Results:Serum and liver LECT2 levels were elevated during hepatic IRI.Serum LECT2 protein and mRNA levels increased post reperfusion.Lect2-knockout mice had reduced weight loss;hepatic necrosis;and serum ALT,AST,creatinine,and BUN levels.rLECT2 treatment exacerbated weight loss,hepatic necrosis,and serum biomarkers(ALT,AST,creatinine,and BUN).AAV-Lect2-shRNA treatment significantly reduced weight loss,hepatic necrosis,and serum biomarkers(ALT,AST,creatinine,and BUN),indicating thera-peutic potential. Conclusions:Elevated LECT2 levels during hepatic IRI increased liver damage.Genetic knockout or shRNA-mediated knockdown of Lect2 reduced liver damage,indicating its therapeutic potential.AAV-mediated Lect2-shRNA delivery mitigated hepatic IRI,offering a potential new treatment strategy to enhance clinical outcomes for patients undergoing liver-related surgeries or trauma.
