ABSTRACT
The effect of omega-3 supplementation on cardiovascular (CV) disease has been widely studied in several large clinical trials. However, the evidence of the effect of omega-3 supplementation in patients with heart failure (HF) remains controversial. This meta-analysis investigated the effects of omega-3 supplementation on patients with HF. We conducted a literature search on MEDLINE, Embase, and Cochrane databases for clinical trials and preprints of relevant articles. Following a literature search and critical appraisal, 5 studies were included in the meta-analysis. The pooling of the result of the studies shows that there were no significant association between omega-3 supplementation and CV mortality (odds ratio [OR], 0.94; 95% confidence interval [CI], 0.84–1.05, p=0.16) nor hospitalization due to HF (OR, 0.94; 95% CI, 0.88–1.02; p=0.13). Our systematic review and meta-analysis showed that omega-3 supplementation has no beneficial effect in patients with HF.
ABSTRACT
Purpose@#Residents’ gender, residency level, and hospital types might influence their attitudes towards clinical supervision (CS); however, reports of its impact on cardiology residency are nonexistent. We explore the effect of gender, residency level, and hospital location’s effect on Indonesian cardiology trainees’ attitudes towards CS. @*Methods@#A multi-centered, cross-sectional study was conducted. We invited 490 Indonesian cardiology residents in September– October 2019 to complete the Cardiology CS Scale. Residents’ attitudes, gender, university, and residency year were expressed using descriptive statistics. A Mann-Whitney test analyzed the gender and university location effect on residents’ attitudes. Training year and university’s impact were subjected to the Kruskal-Wallis test; a p-value of <0.05 reflected a significant result. @*Results@#A total of 388 residents agreed to participate (response rate=79.18%). Most of them were male (n=229 [59,02%]), attended universities in Java Island (n=262 [67,52%]), and were in their 2nd–3rd year of training (n=95 [24.48%], each). There were no significant differences in residents’ attitudes between genders (U [Nmale=229, Nfemale=159]=17,908.50, z=-0.27, p=0.78). Generally, their attitudes were significantly affected by the university (H(7)=47.38, p<0.01). However, the university location (located in Java Island or outside Java Island) does not affect residents’ attitude towards CS (U [NJava=262, Nnon-Java=126]=15,237.00, z=-1.23, p=0.22). In addition, the residents’ training year also affected the residents’ response (H(2)=14.278, p<0.01). @*Conclusion@#Cardiology residents’ attitudes towards CS are significantly influenced by training year and university but not gender or university location. The results might provide insightful information for further improvement of CS in cardiology training and guide further evaluation.
ABSTRACT
Background@#Abdominal obesity is a risk factor for cardiovascular disease and type 2 diabetes mellitus (T2DM). Plasma retinol-binding protein 4 (RBP4) levels have been reported to increase in the abdominally obese subjects and it has been hypothesized that high plasma protein levels were considered to play an important role in the occurrence of T2DM. @*Objective@#We assessed the value of high plasma RBP4 levels as risk factor of T2DM in abdominally obese subjects. @*Methodology@#A case-control study, nested within a cross-sectional study, on 81 abdominally obese subjects was performed. We studied 33 patients with T2DM, compared with 33 matched controls. The plasma RBP4 levels were measured by ELISA. Insulin resistance (IR) status of the patients were determined using HOMA-IR; β-cell function was determined using HOMA-B. Analysis of variance (ANOVA) was used to test the equality of continuous variables. Forward conditional logistic regression analyses were performed to examine the odds ratios (OR) between high plasma RBP4 levels and consequent T2DM. Path analyses models were performed to assess the influence of risk factors on occurrence of T2DM. @*Result@#Plasma RBP4 levels were significantly increased, while HOMA-B was significantly lower in cases with respect to controls. In analyses adjusted for multiple T2DM risk factors, we observed positive association with high plasma RBP4 levels 9.74 (CI 95%; 2.03 – 46.67) (p = 0.004). It has been proven that high RBP4 level was a dominant risk factor (66.9%, p = < 0.001) influencing incidence of T2DM in the abdominally obese subjects.@*Conclusion@#The present study confirmed that high plasma RBP4 level is associated with increased incident T2DM in the abdominally obese subjects, and suggested that RBP4 has a major effect in the development of T2DM.
