RESUMO

BACKGROUND: Vitamin D deficiency is considered an emerging health problem that affects at least one billion patients worldwide. Calcitriol 1,25(OH)2D3 has several systemic effects, including anti-inflammatory, anti-thrombotic and anti-atherosclerotic impacts that explain its cardioprotective effects. The precise association between vitamin D and its metabolites and the value of supplements in acute coronary syndrome (ACS) is still controversial. This study aims to search the association between vitamin D2, D3, and metabolites and ACS in patients undergoing coronary angiography. MATERIALS AND METHODS: This was a case-control study on 73 consecutive adult patients with ACS undergoing coronary angiography compared to 50 controls without coronary artery disease and matched for age and sex from June 2019 till July 2019. Echocardiography and coronary angiography were done for all cases. Plasma vitamin D and its metabolites were measured at admission for all participants along with chemistry profiles. RESULTS: Vitamin D and its metabolites were statistically significantly lower in ACS patients than the controls. Multivariate regression analysis revealed that low levels of 25-hydroxyvitamin D (25(OH)D) and 1,25-dihydroxyvitamin D (1,25(OH)2D) significantly predicted ACS occurrence; the other significant predictors were high systolic blood pressure (BP), high total cholesterol, and low high-density lipoprotein-cholesterol. Interestingly, vitamin D2 and D3 did not significantly predict ACS (p>0.05). We did not find a statistically significant association between the number of affected coronary vessels and vitamin D metabolites. Moreover, there was no statistically significant correlation between vitamin D and its metabolites and left ventricular ejection fraction measured by echocardiography. CONCLUSION: There was a strong association between vitamin D and all its metabolites with ACS. Significantly, low 25(OH)D and 1,25(OH)2D predicted ACS, but vitamin D2 and D3 did not. Large randomized controlled trials are needed to verify the beneficial values of vitamin D supplementation in ACS patients.

RESUMO

Reported natural disasters are steadily increasing, yet there is limited previous research explicitly exploring the predictors of disaster resiliency among older people from typhoon-hit provinces. This study examined the relationships between life satisfaction, attitude, spirituality and locus of control towards resiliency among older adult Typhoon Haiyan survivors. A descriptive correlational design was conducted among these survivors in the Eastern Philippines. Standard multiple linear regression analysis was used in the study. The findings indicated that spirituality and attitude were significant predictors of the survivors' resiliency. The spirituality and positive attitudes of the older adults were associated with disaster resiliency among the typhoon survivors. Thus, the findings suggest the need for nurse gerontologists to promote spirituality and encourage positive attitudes among older adults.
