A multi-center study on the attitudes of Malaysian emergency health care staff towards allowing family presence during resuscitation of adult patients

BACKGROUND The practice of allowing family members to witness on-going active resuscitation has been gaining ground in many developed countries since it was first introduced in the early 1990s. In many Asian countries, the acceptability of this practice has not been well studied. AIM We conducted a multi-center questionnaire study to determine the attitudes of health care professionals in Malaysia towards family presence to witness ongoing medical procedures during resuscitation. METHODS Using a bilingual questionnaire (in Malay and English language), we asked our respondents about their attitudes towards allowing family presence (FP) as well as their actual experience of requests from families to be allowed to witness resuscitations. Multiple logistic regression was used to analyze the association between the many variables and a positive attitude towards FP. RESULTS Out of 300 health care professionals who received forms, 270 responded (a 90% response rate). Generally only 15.8% of our respondents agreed to allow relatives to witness resuscitations, although more than twice the number (38.5%) agreed that relatives do have a right to be around during resuscitation. Health care providers are significantly more likely to allow FP if the procedures are perceived as likely to be successful (e.g., intravenous cannulation and blood taking as compared to chest tube insertion). Doctors were more than twice as likely as paramedics to agree to FP (p-value = 0.002). This is probably due to the Malaysian work culture in our health care systems in which paramedics usually adopt a 'follow-the-leader' attitude in their daily practice. CONCLUSION The concept of allowing FP is not well accepted among our Malaysian health care providers

Genome-Wide Association Study in BRCA1 Mutation Carriers Identifies Novel Loci Associated with Breast and Ovarian Cancer Risk

BRCA1-associated breast and ovarian cancer risks can be modified by common genetic variants. To identify further cancer risk-modifying loci, we performed a multi-stage GWAS of 11,705 BRCA1 carriers (of whom 5,920 were diagnosed with breast and 1,839 were diagnosed with ovarian cancer), with a further replication in an additional sample of 2,646 BRCA1 carriers. We identified a novel breast cancer risk modifier locus at 1q32 for BRCA1 carriers (rs2290854, P = 2.7×10-8, HR = 1.14, 95% CI: 1.09-1.20). In addition, we identified two novel ovarian cancer risk modifier loci: 17q21.31 (rs17631303, P = 1.4×10-8, HR = 1.27, 95% CI: 1.17-1.38) and 4q32.3 (rs4691139, P = 3.4×10-8, HR = 1.20, 95% CI: 1.17-1.38). The 4q32.3 locus was not associated with ovarian cancer risk in the general population or BRCA2 carriers, suggesting a BRCA1-specific associat

The Effect of High-Dose Vitamin A Supplementation Given with Bacille Calmette-Guerin Vaccine at Birth on Infant Rotavirus Infection and Diarrhea: A Randomized Prospective Study from Guinea-Bissau

Background. Prophylactic vitamin A supplementation (VAS) reduces mortality and may reduce morbidity associated with diarrhea in children 16 months of age. Rotavirus is the most common cause of acute dehydrating diarrhea among children worldwide. Methods. In a randomized placebo-controlled study of 50,000 IU of vitamin A versus placebo given with bacille Calmette-Guerin vaccine at birth, 287 infants were followed up with weekly interviews and stool sample obtainment to test the hypothesis that VAS reduced the risk of rotavirus infection. Results. VAS was associated with increased risk of rotavirus infection and diarrhea (incidence rate ratio [IRR] of infection, 1.72 [95% confidence interval (CI), 1.04-2.85]; IRR of diarrhea, 3.74 [95% CI, 1.40-9.98]) among children 6 months of age (IRR, 1.84; 95% CI, 0.96-3.55). Conclusion. VAS at birth did not reduce rotavirus morbidity. The effect of VAS on nonrotavirus diarrhea may differ by sex, being more beneficial in boys.Host-parasite interactio
