Hot bats go cold: heterothermy in neotropical bats
Canadian Journal of Zoology, e-First Articles. Torpor is common in bats, but has historically been viewed as an energy-saving technique reserved for temperate and subarctic climates; however, torpor use is common across several tropical bat families. Central America hosts a great diversity of bats with approximately 150 species, yet data from this area are lacking compared with tropical Africa and Australia. We investigated thermoregulatory responses of bats from neotropical Belize and captured adult bats in the tropical forests of Lamanai Archeological Reserve, Belize. After a 12 h acclimation period, we recorded rectal t...

Correlates and family aggregation of vitamin D concentrations in school-aged children and their parents in nine Mesoamerican countries.
CONCLUSIONS: VDD prevalence was low in this study. Sociodemographic characteristics, diet and outdoor activity predict serum 25(OH)D. Family aggregation of serum 25(OH)D is high between mothers and children. PMID: 28735597 [PubMed - as supplied by publisher] (Source: Public Health Nutrition)

Identification of major routes of HIV transmission throughout Mesoamerica.
CONCLUSION: International clusters were infrequent, suggesting moderate migration between HIV epidemics of the different Mesoamerican countries. Nevertheless, we observed important sources of transnational HIV spread in the region, including Southern and Central Mexico and Belize.

Folate Deficiency Is Prevalent in Women of Childbearing Age in Belize and Is Negatively Affected by Coexisting Vitamin B-12 Deficiency: Belize National Micronutrient Survey 2011 [Community and International Nutrition]
Conclusions: In Belize, the prevalence of folate and vitamin B-12 deficiencies continues to be a public health concern among WCBA. Furthermore, low folate status co-occurred with low vitamin B-12 status, underlining the importance of providing adequate vitamin B-12 and folic acid intake through approaches such as mandatory food fortification.

HIV Risk Behavior and Prevention Considerations Among Military Personnel in Three Caribbean Region Countries: Belize, Barbados, and the Dominican Republic.
Abstract We review research findings and the limitations of recent qualitative and quantitative studies of HIV prevalence and risk behaviors in military populations in three Caribbean countries (Dominican Republic, Belize, and Barbados). This research shows how mental health issues, disordered substance use, and structuring aspects of the occupational field produce and reproduce patterns of risk behaviors. We discuss the use of formative research, the Positive Health, Dignity, and Prevention framework, and the use of implementation science (including research methods that employ alternative methodological ...
