The "Breaking the Cycle" programme, based on the Project Charlie programme, was developed for Antigua and Barbuda third grade students and was implemented in 2001. Aspects of the programme are compared with aspects recently proven effective in randomized studies in developed countries. The "Breaking the Cycle" programme includes life-skills training, teaches decision making skills, includes peer resistance training, uses trained teachers, interactive teaching methods, effective content and delivery, targets students prior to onset of drug use, teaches drug harm, teaches community values and is culturally sensitive, all aspects of successful programmes overseas. The cost of about $7 US per student would suggests cost-benefit effectiveness compared with overseas programmes. The "Breaking the Cycle" school-based drug and alcohol use prevention programme includes most aspects of evidence-based successful programmes overseas, appears cost effective and could serve as a model for programmes in the Caribbean region.
This study was done to assess the age-specific incidence of admission for acute myocardial infarction in Antigua and Barbuda from 1990 to 2001. A retrospective review of Intensive Care Unit admissions for possible acute myocardial infarction was performed. Data obtained included age, gender, country of residence, electrocardiogram, creatine kinase results and intensive care unit outcome. There were, 250 admissions, 194 (78%) having data available for review. Acute myocardial infarction was found in 107/194 (55.2%) patients, age 59.9 +/- 13.7 years, 28% female, 70% from Antigua and Barbuda, 90/107 (85%) were between 35 and 75 years old. The incidence would be 7.5 per year or 9.7 per year if the confirmation rate documented was similar for all admissions. With a yearly population of 9555 men age 35 to 75 years in Antigua and Barbuda, with men accounting for 72% of acute myocardial infarctions, the incidence rate was 0.57 (confirmed) to 0.73 (all admissions) per year per 1000 men. For women, the yearly population was 10822 age 35 to 75 years, and the incidence rate was 0.19 to 0.24 per year per 1000 women. The mortality rate was 12/107 (11.2%), with women being older (67 vs 57 years, p = 0.001) and dying more often (17% vs 9%) compared with men. The mortality rate in the Intensive Care Unit was 0.07 per year for men, 0.04 per year for women per 1000 aged 35 to 75 years. In the United States of America (USA), the admission rate is 4.1 for men and 1.8 for women per year per 1000 aged 35 to 75 years; the mortality rate is 1.0 for men and 0.5 for women per year per 1000 aged 35 to 75 years. Rates of admission to the Intensive Care Unit for acute myocardial infarction in Antigua and Barbuda are 20%, and mortality rates are 10% of those reported in the USA.
In the epidemiological transition from infectious diseases in the Caribbean, chronic non-communicable diseases, including cardiovascular disease, have emerged as important public health interest. Although hypertensive heart disease predominates in Afro-Caribbean populations, ischaemic heart disease and acute myocardial infarction have also been present, but the prevalence has been somewhat under-appreciated.
A 16-year-old adolescent presented with fever, lethargy and vomiting associated with mild dehydration. This was followed less than 24-hours later by loss of consciousness, seizures and clinical brain death. She had no prior medical illness, no hospital or frequent antibiotic exposure. There was no evidence of soft tissue or skin infection. Management included intravenous fluids, ampicillin and cefotaxime parenterally, dexamethasone, endotracheal intubation and mechanical ventilation. Her neurologic examination remained unchanged with areflexia, flaccid paralysis and fixed pupils. Post-mortem examination revealed an eight-centimetre right fronto-parietal lobe brain abscess. Cultures were positive for methicillin resistant Staphylococcus aureus. Although formerly a nosocomial pathogen affecting debilitated patients in the hospital setting, S aureus that is methicillin resistant is emerging as a community acquired pathogen affecting previously well patients.
Increased left ventricular mass (LVM) on echocardiogram is an independent risk factor for cardiac complications from hypertension. It is associated with a four-fold increase in untoward cardiac events when present. Data were reviewed for 100 treated hypertensive Afro-Caribbean patients, aged 29 to 65 years, recruited from village health clinics. Age, gender, height, weight, systolic and diastolic blood pressure, echocardiogram (ECHO) and drug history were recorded for each patient. The best single predictor of increased LVM was blood pressure with systolic (163 vs 152 mmHg, p < 0.01) and diastolic blood pressure (105 vs 98, p < 0.01) being significantly higher in patients with increased LVM. Systolic blood pressure over 150 mmHg was associated with increased LVM in 64% vs 44% below 150 mmHg (p < 0.10). Diastolic blood pressure over 95 mmHg was associated with increased LVM in 63% vs 36% below 95 mmHg (p < 0.02). BMI showed a trend (31.1 vs 29.7 kg/m2, p < 0.20) toward higher values in patients with increased LVM. BMI above 28 kg/m2 was associated with increased LVM in 61% vs 44% below that value (p < 0.15). Females more than males had increased LVM (61% vs 44%, p = 0.30) possibly due to higher BMI (31 vs 29.4 kg/m2) and higher systolic blood pressure (160 vs 155 mmHg). Age (48.3 vs 46.5 years, p = 0.30) and years of hypertension (8.6 vs 7.3 years, p = 0.33) were not significantly different between the two groups. Drug treatment was reported in 90% (69% monotherapy, 27% > one drug, 4% > 2 drugs) and no drug was associated with significant difference in LVM compared to others. Only 15% of treated hypertensive patients had systolic blood pressure below 140 mmHg and 8% had diastolic blood pressure below 90 mmHg. The major determinant of increased LVM in this group of Afro-Caribbean hypertensive patients appears to be poorly controlled hypertension with obesity being a possible contributing factor
Group B streptococcus is the most common cause of neonatal sepsis in the United States of America (USA). This study was undertaken to determine the contribution of group B streptococcus to neonatal septicaemia in Antigua and Barbuda. From 1994 to 2002, there were about 12,000 births, with 2500 Special Care Nursery admissions, 1100 (44%) with potential neonatal septicaemia. Blood cultures were done in 433/1100 (39%) and cerebrospinal fluid cultures in 52/1100 (5%). Positive cultures were seen in 41/433 (9.5%) with group B streptococcus in 1/41 (2.4%), streptococcus "species" in 3/41 (7.4%) and positive cerebrospinal fluid cultures were seen in 2/52 (one group B streptococcus) giving 5 per 12,000 or 0.4 cases per 1000 babies. Vaginal cultures from 1994 to 2002 revealed group B streptococcus in 14/163 (8.6%) of positive bacterial cultures. A sample of pregnant women from a private office had positive culture for group B streptococcus in 2/120 (1.7%). The prevalence rate of carriage (15 to 40%) and infection (1.7 to 4 per 1000 babies) was much higher in the USA in the same period Universal screening of mothers for group B streptococcus may not be as necessary or cost-effective in Antigua and Barbuda.
