INTRODUCTION Helicobacter pylori (H. pylori) infection is usually acquired in childhood. In Cuba, its study in pediatric ages is a little explored field. AIM To identify the prevalence of the infection and its associated risk factors in 3-year-old children in Havana. MATERIALS AND METHODS An analytic, cross-sectional, epidemiologic analysis was conducted on 1,274 children belonging to the cohort of participants in the Natural History of Wheezing in Cuba study (HINASIC for its Spanish acronym) that were 3 years of age and provided a stool sample. H. selleckchem pylori infection was identified by determining the H. pylori antigen (Ag) in stool, utilizing the commercial Spinreact kit, from Spain. The data were collected through a questionnaire applied by the researchers that included sociodemographic, environmental, and lifestyle variables, as well as infection from other parasites. Prevalence and the prevalence ratio with a 95% confidence interval were calculated and the dichotomous logistic regression analysis was employed. RESULTS The prevalence of positive H. pylori Ag was 5%. Sleeping together was the risk factor found (PR1.27; 95% CI 1.03-1.50). Protective factors were drinking water from water delivery trucks (PR 0.16; 95% CI 0.04-0.72) and living in a nuclear family unit (PR 0.94; 95% CI 0.85-0.99). CONCLUSIONS The prevalence of H. pylori infection in early childhood places Havana in an intermediate position at the international level. To control the infection, causal studies should be conducted and opportune interventions implemented. OBJECTIVES Drawing from social identity threat theory, which posits that stigmatized groups are attuned to situational cues that signal racial bias, we examined how African-American veterans evaluate verbal and non-verbal cues in their mental health encounters. We also explored how their evaluations of perceived racial bias might influence their healthcare engagement behaviors and communication. METHODS We interviewed 85 African-American veterans who were receiving mental health services from the US Department of Veterans Affairs (VA), examining their views and experiences of race in healthcare. We analyzed the data using a constructivist grounded theory approach. RESULTS Participants identified several identity threatening cues that include lack of racial diversity representation in healthcare settings, and perceptions of providers' fears of Black patients. We describe how participants evaluated situational cues as identity threats, and how these cues affected their engagement behaviors and healthcare communication. CONCLUSION Our findings revealed situational cues within clinical encounters that create for Black veterans, fear of being negatively judged based on stereotypes that have characterized African-Americans. PRACTICE IMPLICATIONS We discuss the implications of these findings and provide suggestions on how to create identity safe environments for minority patients that include delivery of person-centered care, and organizational structures that reduce providers' burnout. Published by Elsevier B.V.With the steadily increasing prevalence of Alzheimer's disease (AD) and great difficulties encountered for AD drug development presently, much interest has been devoted to identifying modifiable risk factors to lower the risk of AD, while the causal associations between risk factors and AD remain inconclusive. The present study conducted a comprehensive evaluation of the causal associations between risk factors and AD development by taking the recent advancements of Mendelian randomization (MR). Inverse variance weighted (IVW), MR-Egger, weighted median, and weighted mode were used for complementary calculation. A total of 45 risk factors and corresponding studies were covered in the study. This two-sample MR (2SMR) analysis provided a suggestive association between genetically predicted higher years of schooling and reduced risks of AD, and each standard deviation (3.71 years) increased in years of schooling was associated with a 41% reduction in the risk of AD (IVW, OR 0.59, 95% CI 0.45-0.77). At the same time, it was genetically predicted that urate might be a risk factor in AD, and it was found that each standard deviation increase in urate levels (1.33 mg/dL) was associated with a 0.09-fold increase in the risk of AD (IVW, OR 1.09, 95% CI 1.01-1.18). To summarize, the 2SMR analysis indicated a suggestive association between genetically predicted higher years of schooling and reduced risks of AD, and between genetically predicted higher urate levels and increased risks of AD. The findings provide useful clues to help combat AD and warrants future studies. Ultrasonography (US) has been used as a reliable imaging modality, providing real-time information during neurosurgical operations. One recent innovative US technique, superb microvascular imaging (SMI), visualizes small vessels and flow, which are not detected with standard US with doppler. We apply SMI to intraoperative US monitoring in emergency surgery for intracerebral hemorrhage (ICH). Eleven consecutive patients with ICH underwent endoscopic emergency surgery under US monitoring with SMI. After performing a small craniotomy, US images were obtained using SMI, a fusion technique, and a contrast agent technique, with the probe on the brain surface during surgery. Fusion images were obtained with the probe on the head before craniotomy in some patients. Animated US images with SMI could differentiate hematoma containing no vessels from brain tissue, and flow images using SMI and contrast agent techniques clarified the borderlines. Animated fusion images of intraoperative US and preoperative CT provided information on the extent of hematoma and residual hematoma during emergency surgery. We made various fusion CT images showing intracranial hematoma with US probes and decided on the skin incision line before beginning surgery, as if we were using a neuronavigation system. US with SMI, contrast agent, and fusion techniques provide information on the extent of intracranial hematoma and residual hematoma with no vessels and no flow. Monitoring by US and fusion CT images is useful for ICH surgery as a next-generation neuronavigator.
