OBJECTIVES: Apolipoprotein E gene (APOE) polymorphism is associated with the lipid profile and cardio-vascular disease. However, these relationships vary between ethnic groups. We evaluated, for the first time in an Afro-Caribbean population, the distribution of APOE polymorphisms and their associations with coronary artery disease (CAD), the lipid profile and other cardio-metabolic risk factors. METHODS: We studied 712 Afro-Caribbean subjects including 220 with documented CAD and 492 healthy subjects...

The loss of regulating agents such as parasites is among the most important changes in biotic interactions experienced by populations established in newly colonized areas. Under a relaxed parasite pressure, individuals investing less in costly immune mechanisms might experience a selective advantage and become successful colonizers as they re-allocate resources to other fitness-related traits. Accordingly, a refinement of the evolution of increased competitive ability (EICA) hypothesis proposed that immunity of invasive populations has evolved toward a reduced investment in innate immunity, the most costly component of immunity, and an increased humoral immunity that is less costly...

Object recognition memory is the ability to identify previously seen objects and is an adaptive mechanism that increases survival for many species throughout the animal kingdom. Previously believed to be possessed by only the highest order mammals, it is now becoming clear that fish are also capable of this type of memory formation. Similar to the mammalian hippocampus, the dorsolateral pallium regulates distinct memory processes and is modulated by neurotransmitters such as dopamine. Caribbean bicolour damselfish (Stegastes partitus) live in complex environments dominated by coral reef structures and thus likely possess many types of complex memory abilities including object recognition...

Disease outbreaks continue to reduce coral populations worldwide. Understanding coral diseases and their relationships with environmental drivers is necessary to forecast disease outbreaks, and to predict future changes in coral populations. Yet, the temporal dynamics of coral diseases are rarely reported. Here we evaluate trends and periodicities in the records of three common coral diseases (white-band disease, yellow-band disease, and dark-spot syndrome) that were surveyed between 1997 and 2014 at 2082 sites throughout the Caribbean...

PURPOSE: Little is known about black African (BA) and black African-Caribbean (BAC) men's views towards cancer; yet culture and acculturation can contribute to the way in which people understand, explain and develop their attitudes towards cancer. Hence, cancer prevention and early detection strategies may not be sensitive to United Kingdom (UK)-based black men's views, affecting their awareness of risk factors and early detection services. This study explored the views of UK-based BA and BAC men towards cancer...

More than 700,000 cases of Zika virus (ZIKAV) disease have been officially reported to the Pan American Health Organization (PAHO) from 48 countries and territories of the Americas. The response led by the PAHO and partners suggests major lessons of this outbreak. A seemingly innocuous pathogen became the new villain, causing fear, economic losses and, most importantly, debilitating birth defects and neurological problems, reaffirming the well-known war principle of never to underestimate one's opponent. The ZIKAV tested public health capacities under the International Health Regulations, highlighting the need for continued investment in health security...

AbstractStarting in 2013-2014, the Americas have experienced a massive outbreak of Zika virus (ZIKV) which has now reached at least 49 countries. Although most cases have occurred in South America and the Caribbean, imported and autochthonous cases have occurred in the United States. Aedes aegypti and Aedes albopictus mosquitoes are known vectors of ZIKV. Little is known about the potential for temperate Aedes mosquitoes to transmit ZIKV. Aedes vexans has a worldwide distribution, is highly abundant in particular localities, aggressively bites humans, and is a competent vector of several arboviruses...

PURPOSE: While falls are common in older people, causing significant mortality and morbidity, this phenomenon has not been extensively studied in the Caribbean. This study aimed to compare falls in older and younger people in this setting. METHODS: We conducted a prospective observational study of older trauma patients in Trinidad, comparing older and younger patients sustaining falls. RESULTS: 1432 adult trauma patients were included (1141 aged 18-64 years and 291 aged 65 years and older)...

AIM: Chicken astroviruses (CAstV) are known to cause mild gastroenteritis, growth depression, and even mortality in poultry, especially in chickens, turkeys, and ducks. To the best our knowledge, there is no published information on CAstV in Grenada. This study was conducted to determine the prevalence of astrovirus in chickens in Grenada. MATERIALS AND METHODS: Blood samples from 366 indigenous chickens and 92 commercial chicken layers were collected from all parishes of the island and tested for antibodies against CAstV using commercial enzyme-linked immunosorbent assay...

Animals communicate using a variety of signals that differ dramatically among and within species. The astonishing dewlap diversity in anoles has attracted considerable attention in this respect. Yet, the evolutionary processes behind it remain elusive and have mostly been explored for males only. Here, we considered Anolis sagrei males and females to study signal divergence among populations. First, we assessed the degree of variation in dewlap design (size, pattern, colour) and displays by comparing 17 populations distributed across the Caribbean...

Trichocorixa verticalis (T. verticalis), native to North America and the Caribbean islands, is an invasive waterboatman species (Corixidae) in the southwest of the Iberian Peninsula. Previous studies in the native range have suggested that predation by T. verticalis can regulate the abundance of Anostracan and Cladoceran zooplankton in saline ecosystems, causing increases in phytoplankton through a trophic cascade. In this experimental study, we tested the predator-prey relationship between the native brine shrimp Artemia parthenogenetica, and T...

Minimally invasive surgery is rapidly expanding its role in almost all of the surgical sub-specialties. There is also a growing demand of this service as patients became more and more concerned about cosmesis in addition to their original surgery. Although its role in thyroid surgery has already been proven earlier; but it is not yet accepted as a routine approach amongst many thyroid surgeons. There is no reported case of laparoscopic thyroid surgery in the English literature from the Caribbean. We are reporting our first clinical experience in performing laparoscopic thyroid surgery in the Caribbean with a successful outcome...

REVIEW
Ken Obenson, George Enow Orock
A properly operated death investigation system (DIS) serves multiple stakeholders. Law enforcement, public health departments and members of the public, benefit in various ways from the information that it provides. This information must be collected systematically and efficiently. The system must also be flexible enough to respond to pressures on its resources such as occurs during mass disasters. These obligations on a DIS require an investment of public money. However even in affluent Western countries the recent world economic crisis has led to a cut in spending on public services that affect both the healthcare system and services associated with death investigation...

Adolescent fertility rates in Latin America and the Caribbean (LAC) remain unacceptably high, especially compared to the region's declining total fertility rates. The Region has experienced the slowest progress of all regions in the world, and shows major differences between countries and between subgroups in countries. In 2013, LAC was also noted as the only region with a rising trend in pregnancies in adolescents younger than 15 years. In response to the lack of progress in the LAC region, PAHO/WHO, UNFPA and UNICEF held a technical consultation with global, regional and country-level stakeholders to take stock of the situation and agree on strategic approaches and priority actions to accelerate progress...

BACKGROUND: Alcohol use is a pervasive and costly public health problem in the United States. Relapse rates from alcohol use disorders are high. Although exercise has been proposed as a strategy to prevent relapse, lifestyle modification is the least studied aspect of relapse prevention programs, especially among racial/ethnic minority populations. OBJECTIVE: The current study assessed whether being physically active was associated with remission from alcohol abuse or dependence among Black (African American and Afro Caribbean) adults in the U...

Rat lungworm, Angiostrongylus cantonensis, is one major cause of human eosinophilic meningitis. This helminth is endemic in Southeast Asia, Pacific Islands, and the Caribbean and has recently expanded to South America. The infection is characterized by an elevated eosinophil count in cerebrospinal fluid. Common symptoms and signs include headache, neck stiffness, paresthesia and nausea/vomiting. The unique history of eating freshwater and land snails or slugs within 2 weeks before onset is helpful for diagnosis...

Michael J Durako, Jacqueline F Howarth
Thalassia testudinum (turtle grass) is the dominant and climax-successional seagrass species in the subtropical/tropical Atlantic and Caribbean region. Two die-offs of T. testudinum in Florida Bay, United States have raised concerns regarding the resilience of this species to environmental disturbances. Seedlings are important in recovery of T. testudinum, following disturbance events. Leaf spectral reflectance [R(λ)] was measured in T. testudinum seedlings exposed for 2 weeks to three salinities (20, 35, and 50) and two light levels (full sun and 50-70% light reduction) in experimental mesocosms...

Symbioses between eukaryotes and sulfur-oxidizing (thiotrophic) bacteria have convergently evolved multiple times. Although well described in at least eight classes of metazoan animals, almost nothing is known about the evolution of thiotrophic symbioses in microbial eukaryotes (protists). In this study, we characterized the symbioses between mouthless marine ciliates of the genus Kentrophoros, and their thiotrophic bacteria, using comparative sequence analysis and fluorescence in situ hybridization. Ciliate small-subunit rRNA sequences were obtained from 17 morphospecies collected in the Mediterranean and Caribbean, and symbiont sequences from 13 of these morphospecies...
