Comparative Study
Predicting 24-hour urinary sodium excretion in Afro-Caribbean Barbadians by comparing urine sodium excretion over different durations versus spot collection.
Urinary sodium excretion is used as an assessment tool for salt intake and salt handling. Even though cumbersome, the most reliable and readily used method in clinical and epidemiological studies is the 24-hour urine collection. This study investigates other appropriate means ofpredicting 24-hour urinary sodium excretion in a sample of Afro-Caribbeans in Barbados by assessing the correlation of actual and estimated urinary sodium excretion between a 24-hour urine collection sample, 12-hour (AM and PM), and spot (AM and PM) urine collections. ⋯ Overall, this study shows a clear correlation between the estimated 24-hour sodium excretion from the 12-hour timed PM sample and the measured 24-hour sodium excretion. Such findings support the thought of using other alternatives to determine sodium excretion, in view of replacing the cumbersome 24-hour urinary collection with a smaller timed sample. Nonetheless, a more robust and randomized population sample as well as a method to correct for high creatinine variability is required to further enhance the significance of the obtained results.

The gold standard for the determination of proteinuria, an independent risk factor for cardiovascular and renal disease, is the measurement of protein in a 24-hour urine collection. However this method has been shown to be unreliable mainly due to poor compliance of sampling by patients. This study investigates other appropriate means of predicting 24-hour urinary protein excretion in a sample of Afro-Caribbeans in Barbados by assessing the correlation of actual and estimated urinary protein excretion between a 24-hour urine collection sample, 12-hour (AM and PM) and spot (AM and PM) urine collections. ⋯ The use ofa 12-hour timed sample, specifically the morning sample, may be a more convenient way to assess proteinuria in the Afro-Caribbean population. This method allows for a quicker assessment of proteinuria which not only allows earlier diagnosis of renal disease but may also reduce the clinical cost of the disease s management.

Observational Study
Severe sepsis in the emergency department - an observational cohort study from the university hospital of the West Indies.
To describe the incidence, treatment and outcomes of patients with severe sepsis and septic shock in a setting where early goal directed therapy (EGDT) is not routinely performed. ⋯ Despite a lack of EGDT, sepsis treatment patterns were consistent with "best-practice" and mortality was lower than international comparators.

Medical tourism, which is the intentional travel by private-paying patients across international borders for medical treatment, is a sector that has been targeted for growth in many Caribbean countries. The international development of this industry has raised a core set of proposed health equity benefits and drawbacks for host countries. ⋯ In this viewpoint, we introduce questions of environmental health equity that clearly emerge in relation to the developing Caribbean medical tourism sector These questions acknowledge that the growth of this sector will have impacts on the social and physical environments, resources, and waste management infrastructure in countries. We contend that in addition to addressing the wider health equity concerns that have been consistently raised in existing debates surrounding the growth of medical tourism, planning for growth in this sector in the Caribbean must take environmental health equity into account in order to ensure that local populations, environments, and ecosystems are not harmed by facilities catering to international patients.
