Objective: We describe diet quality by demographic factors and weight status among Barbadian children and examine associations with excess energy intake (EI). A screening tool for the identification of children at risk of excess EI was developed.
Design: In a cross-sectional survey, the Diet Quality Index-International (DQI-I) was used to assess dietary intakes from repeat 24h recalls among 362 children aged 9-10 years.
Study Objective: We endeavor to assess the impact of introduction of guidelines for preoperative investigations (PIs) on anesthetic practices and costs and compare their efficacy to current practices.
Design: A prospective study.
Setting: Queen Elizabeth Hospital, Barbados.
Objective: To evaluate the clinical performance of brackets cured with a high-intensity, light-emitting diode (LED) with a shorter curing time.
Materials And Methods: Thirty-four patients and a total of 680 brackets were examined using a randomized split-mouth design. The maxillary right and mandibular left quadrants were cured for 6 seconds with a high-intensity LED light (3200 mW/cm(2)) and the maxillary left and mandibular right quadrants were cured for 20 seconds with a standard-intensity LED light (1200 mW/cm(2)).
Approximately 25% of patients undergoing carotid endarterectomy (CEA) exhibit cognitive dysfunction (CD) 1 day and 1 month after CEA. The apolipoprotein E (apoE)-ε4 polymorphism has been previously identified as a robust independent risk factor for CD 1 month after CEA. We aimed to determine whether the apoE-ε4 polymorphism is also an independent risk factor for CD as early as 1 day after CEA and to confirm the previous findings at 1 month.

- SNP 83, a polymorphism in the PDE4D gene, was studied to see if it affects cognitive dysfunction after carotid endarterectomy (CEA).
- Patients with the C/C genotype of SNP 83 had a significantly higher rate of cognitive dysfunction 1 day post-surgery compared to those with C/T and T/T genotypes.
- The findings suggest that inflammation caused by this genotype could play a role in cognitive issues after surgery, but further research is needed to confirm this link.
Object: The role of genetic polymorphisms in the neurological outcome of patients after carotid endarterectomy (CEA) remains unclear. There are single nucleotide polymorphisms (SNPs) that predispose patients to postoperative cognitive dysfunction (CD). We aim to assess the predictability of three complement cascade-related SNPs for CD in patients having CEAs.

- Statins show neuroprotective effects in patients undergoing carotid endarterectomy, potentially reducing the risk of neurological injury.
- In a study of 328 patients, those taking statins experienced significantly lower rates of clinical stroke (0.0% compared to 3.1%) and cognitive dysfunction (11.0% vs 20.2%).
- The findings suggest that preoperative statin use can help minimize perioperative neurological complications, indicating a potential for improved patient outcomes in carotid surgeries.
