A Case for a Holistic Approach to the Improvement of Compliance among Hypertensive Patients: A Hospital Review.

The second Jamaica Health and Lifestyle Survey completed in 2007-2008 provided evidence that the prevalence of hypertension has increased significantly since 2000-2001. With more of the population living with hypertension, greater will be the need to ensure the best quality of life. A recent survey conducted in the ambulatory section of the Emergency Medicine Division at the University Hospital of the West Indies, identified a 36.5% non-compliance rate among the 52 patients prescribed with antihypertensive drugs. The reasons given for non-compliance with their antihypertensive medications are not new and included adverse effects, inconvenience and fear of dependence. However, in the same survey, it was also found that blood pressure was poorly controlled in 69.7% of the self-reported compliant subjects. Together, these points suggest that simply providing access to drugs is inadequate and a more holistic approach will be required to reduce blood pressure at the population level.

The Use of Analgesic Drugs in Patients with Sickle Cell Painful Crisis.

OBJECTIVE: To determine the drug options used for pain in patients with acute sickle cell painful crisis at the University Hospital of the West Indies (UHWI), Jamaica. METHOD: This retrospective study assessed all patients admitted to the UHWI between January 1, 2006 and December 31, 2010 with acute sickle cell anaemia painful crisis and the data obtained regarding site, severity, outcome and drug options selected for pain. RESULTS: There were 101 patients with a mean age (± SD) of 18.6 (± 14.3) years; there was no difference in gender (42 females, 59 males). Eight sites of pain were reported, with the most common site being the lower limbs (44.6%) and 60.3% experienced pain in more than one site. Most of the patients (75.2%) were diagnosed with severe pain. Drug options included opioid, non-opioid or a combination, with pethidine (76) and paracetamol (79) being the most common chosen opioid and non-opioid drugs selected for therapy. There was low correlation between pain severity and appropriate first-line treatment (Spearman's rho = 0.344; p < 0.000). All patients with "mild" and "mild to moderate" pain were initially treated and obtained resolution of pain with non-opioid based therapy. However, most of the patients with severe pain (55.3%) required a second-line and some third-line (14.5%) of therapy for resolution at the time of discharge from the hospital. CONCLUSION: Painful crisis in patients with sickle cell anaemia is associated with severe pain in 75% and most will require second-line therapy for adequate resolution. Physicians need to provide adequate pain relief to decrease morbidity in these patients.

Monoclonal Antibodies in Cancer Therapy: Mechanisms, Successes and Limitations.

Rituximab was the first chemotherapeutic monoclonal antibody (CmAb) approved for clinical use in cancer therapeutics in 1997 and has significantly improved the clinical outcomes in non-Hodgkin's lymphoma. Since then, numerous CmAbs have been developed and approved for the treatment of various haematologic and solid human cancers. In this review, the classification, efficacy and significantly reduced toxicity of CmAbs available for use in the United States of America are presented. Finally, the limitations of CmAbs and future considerations are explored.

A Review of Pharmacovigilance.

Pharmacovigilance supports safe and appropriate use of drugs. Spontaneous reporting of adverse drug reactions (ADRs) is an essential component of pharmacovigilance. However, there is significant underreporting of ADRs. Adverse drug reactions have become a major problem in developing countries. Knowledge of pharmacovigilance could form the basis for interventions aimed at improving reporting rates and decreasing ADRs.

The antimicrobial screening of a Barbadian medicinal plant with indications for use in the treatment of diabetic wound infections / Tamizaje antimicrobiano de una planta medicinal Barbadense con indicaciones para su uso en el tratamiento de infecciones de heridas en diabéticos

OBJECTIVE: Diabetes mellitus is a chronic noncommunicable disease with high prevalence in the North American and Caribbean region. Diabetic Foot Syndrome which is an associated complication can lead to the development of wounds and ulcers which can become infected. Justicia secunda, a plant known locally in Barbados as Bloodroot used in folklore for wound healing, was selected to test its ability to aid diabetic wound healing by antimicrobial activity. It was therefore tested against the bacteria Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, and Enterococcus feacalis (clincal strain) which are commonly found in diabetic wounds. METHODS: The plant was collected by local users. Methanol and acetone extracts of the plant were prepared with use of soxhlet extraction. The antimicrobial activity was assessed with the use of a modified KirbyBaurer method. Concentrations of 200 mg/ml, 100 mg/ml, 10 mg/ml, and 1 mg/ml of the extract were used, with a standard ciprofloxacin 5 µg positive control, and a 5% dimethyl sulfoxide (DMSO) solution negative control. RESULTS: The J secunda methanol and acetone extracts with an extraction yield of 15.3% and 0.75%, respectively yielded no activity within the concentration range against the three strains of bacteria tested. In comparison with the positive control, relative inhibition zone diameter (RIZD) values of 0% resulted for both the negative control and the extracts, with the positive control having a value of 100%. CONCLUSION:The in vitro screen of the extracts prepared from J secunda, yielded no antimicrobial activity against the three strains of bacteria tested and therefore does not support the folklore claims by this mechanism of action.

OBJETIVO: La diabetes mellitus es una enfermedad crónica no transmisible, de alta prevalencia en la región de Norte América y el Caribea. El síndrome de pie diabético es una complicación asociada, que puede llevar al desarrollo de heridas y úlceras, con la consiguiente posibilidad de infección. Justicia segunda es una planta conocida localmente en Barbados como "bloodroot" (sanguinaria canadensis) y usada en la medicina folklórica para la curación de heridas. Esta planta fue seleccionada para analizar su capacidad de ayudar a curar las heridas de diabéticos por su actividad antimicrobiana. Por lo tanto, se la sometió a prueba frente a bacterias Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, y Enterococcus feacalis (cepa clínica) que normalmente se encuentran en las heridas del diabético. MÉTODOS: La planta fue proporcionada por usuarios locales. Usando un extractor Soxhlet, se prepararon extractos de metanol y acetona a partir de la planta. La actividad antimicrobiana se evaluó mediante el método de KirbyBauer modificado. Se usaron concentraciones de 200 mg/ml, 100 mg/ml, 10 mg/ml, y 1 mg/ml del extracto, con un control positivo de 5 µg de ciprofloxacina estándar, y un control negativo de una solución de dimetil sulfóxido (DMSO) al 5%. RESULTADOS: Los extractos de metanol y acetona de J secunda con un rendimiento de extracción de 15.3% y 0.75% respectivamente, no arrojaron actividad alguna dentro del rango de la concentración contra las tres cepas de bacterias sujetas a prueba. Comparado con el control positivo, el diámetro de la zona de inhibición relativa (RIZD) arrojó valores de 0%, tanto para el control negativo como para los extractos, con un valor de 100% para el control positivo. CONCLUSIÓN: El tamizaje in vitro de los extractos preparados de J secunda, no arrojó actividad antimicrobiana alguna contra las tres cepas de bacterias analizadas, y por consiguiente no sustenta la afirmación de la medicina folklórica en relación con este mecanismo de acción.

Preference of patient information leaflets over standard drug monographs by patients prescribed hydrochlorothiazide, nifedipine and enalapril.

Standard drug monographs (SDMs) have been described as deficient in providing information in a manner simplified enough for patient reading. The aim of this study was to design patient information leaflets for hydrochlorothiazide, nifedipine and enalapril with content indicated by patients as relevant and to evaluate them against the SDM. Patient information leaflet (PIL) for each drug was designed to contain information on name, use of drug, how it works, how it is to be taken, common side effects, storage, missed dose action, things to avoid and when to contact the physician. Appropriateness was assessed by 10 practising pharmacists. For each drug, 40 patients were recruited, of which 20 were given SDM and 20 PIL. The knowledge of each participant was examined before and after exposure to SDM or PIL, as well as opinion on ease of reading and attractiveness using Pearson s Chi-square analysis. The results showed that both SDM and PIL improved knowledge of common side effects when compared with responses before exposure (chi2 = 24.26 for SDM and 27.64 for PIL, p < 0.001) with no difference between the groups. Respondents receiving PILs were better able to recall "things to avoid" after exposure to PIL (chi2 =10.85, p < 0.001). After exposure to SDM or PIL, the respondents who received PIL were more aware of when to contact the physician, compared to the SDM group (chi2 = 8.41, p < 0.01). When compared with SDM, respondents receiving PIL were more likely to indicate that PIL was easy to read (chi2 = 20.00, p < 0.001), attractive (chi2 = 12.45, p < 0.001) and they were more likely to recommend distribution of their reading material to other patients (chi2 = 22.11, p < 0.001). We conclude that there is benefit in designing information leaflets that simplify language and medication information contained in SDMs, including better understanding of precautions to take while on medication and when to consult physicians.

Prevalence of the metabolic syndrome in patients presenting to the University Hospital of the West Indies: a need to adopt proactive screening and specific management policy / Prevalencia del síndrome metabólico en pacientes que acuden al Hospital Universitario de West Indies: necesidad de adoptar un tamizaje proactivo y políticas de tratamiento específico

Studies have shown that the metabolic syndrome (MetS), a major risk factor for the development of Type 2 diabetes mellitus and cardiovascular disease, is higher among psychiatric patients on antipsychotic medications than the general population. While studies on the prevalence of MetS in the Jamaican adult population have been undertaken, no such study has been done on the corresponding psychiatric population. The purpose of this study was to determine the prevalence of MetS in a Jamaican adult psychiatric inpatient population. The study group comprised thirty-eight patients with a primary DSM-IV-TR Axis 1 diagnosis. Criteria for the diagnosis of MetS were the presence of any three or more of five factors as defined by using the International Diabetes Federation (IDF) and American Heart Association/National Heart Lung and Blood Institute (AHA/NHLBI) consensus agreement. The prevalence of MetS in this cohort was 28.9% and was associated with significantly higher abdominal obesity (p = 0.010), elevated blood pressure (p = 0.000), elevated triglycerides (p = 0.019) and low high density lipoprotein-cholesterol (p = 0.016) when compared with patients not diagnosed with MetS. Metabolic syndrome was common in this group of psychiatric patients and likely represents a pathway to the future development of Type 2 diabetes mellitus and cardiovascular disease. Screening and continuous monitoring will allow for early intervention and possibly prevention of increased morbidity and mortality in this vulnerable population.

Los estudios han mostrado que el síndrome metabólico (SMet) - un factor de riesgo mayor para el desarrollo de la diabetes mellitus tipo 2 y la enfermedad cardiovascular - es más alto entre los pacientes psiquiátricos bajo medicamentos antipsicóticos que entre la población general. Si bien se han llevado a cabo estudios sobre la prevalencia del SMet en la población adulta jamaicana, no se han realizado estudios de esta clase en la población psiquiátrica correspondiente. El propósito de este estudio fue determinar la prevalencia del SMet en una población jamaicana adulta de pacientes hospitalizados. El grupo de estudio comprendió treinta y ocho pacientes con diagnóstico primario DSM-IV-TR de eje I. Los criterios para el diagnóstico de SMet se basaron en la presencia de tres o más de cinco factores, los cuales fueron definidos usando el acuerdo por consenso de la Federación Internacional de la Diabetes (FID) y la Asociación Nacional de Cardiología/Instituto Nacional del Corazón, el Pulmón y la Sangre (AHA/NHLBI). La prevalencia de SMet en esta cohorte fue 28.9%, y se hallaba asociada con obesidad abdominal significativamente más alta (p = 0.010), presión sanguínea elevada (p = 0.000), triglicéridos elevados (p = 0.019), y bajos niveles de colesterol-lipoproteína de alta densidad (p = 0.016), al compararse con pacientes no diagnosticados con SMet. El síndrome metabólico fue común en este grupo de pacientes psiquiátricos y probablemente representa una vía al desarrollo futuro de la diabetes mellitus tipo 2 y la enfermedad cardiovascular. El tamizaje así como el monitoreo continuos permitirán la intervención temprana y la posible prevención del aumento de la morbosidad y la mortalidad en esta población vulnerable.

Suicide attempt by self-poisoning: characteristics of suicide attempters seen at the emergency room at the University Hospital of the West Indies / Intento de suicidio por envenenamiento: características de los que intentan suicidio, observadas en la sala de emergencia del Hospital Universitario de West Indies

OBJECTIVE: To document the characteristics of self-poisoning suicide attempters who were brought to the University Hospital of the West Indies (UHWI) Emergency Room and to outline the type of drug used in the attempt. METHOD: This was a retrospective study conducted over the period 2005-2009. Data were gathered from patients' case records, log books and the hospital records using a questionnaire developed for this study. The questionnaire examined demographics, parameters of the drug ingested, patient's disposition, and reasons for attempt, final outcome and the type of discharge of patients who reported to the UHWI Emergency Room due to a suicide attempt by self-poisoning. RESULTS: Over the five-year period, 127 cases of suicide attempt by self-poisoning were reported. Significantly more females than males presented to the hospital due to self-poisoning (3:1, χ² = 33.37; p < 0.001). Of this amount, 96 cases (75.6%) were females and 31 (24.4%) were males. The age group most recorded was 16-30 years (70.8%). The most common reason for the suicide attempt was an interpersonal conflict (52%). The drug category most often used in self-poisoning was analgesics (52%) with acetaminophens being the most common (26.2%). CONCLUSION: These findings are consistent with global suicide trends and indicate an urgent need to develop and implement national preventative and treatment measures for groups known to be at risk of suicidal attempts.

OBJETIVO: El objetivo del presente trabajo es, por un lado, documentar las características de personas con ánimo suicida, trasladadas a la Sala de Emergencia del Hospital de West Indies (HUWI), tras el intento de cometer suicidio por envenenamiento, y por otro, describir el tipo de medicamento utilizado en el intento. MÉTODO: Se trata de un estudio retrospectivo llevado a cabo en el periodo 2005-2009. Se recogieron datos provenientes de las historias clínicas de los pacientes, los diarios, y los archivos del hospital, usando un cuestionario desarrollado específicamente para este estudio. El cuestionario examinó los datos demográficos, los parámetros del medicamento ingerido, la disposición del paciente, y las razones del intento, así como la evolución clínica y el tipo de alta de los pacientes reportados en la Sala de Emergencias del HUWI, debido a un intento suicida por envenenamiento. RESULTADOS: En el periodo de cinco años, se reportaron 127 casos de intento de suicidio por envenenamiento. Significativamente más hembras que varones se presentaron al hospital debido a envenenamiento (3:1, χ² = 33.37; p < 0.001). De este número, 96 casos (75.6%) fueron hembras y 31 (24.4%) fueron varones. El grupo etario más registrado fue el de 16-30 años (70.8%). La razón más común para la tentativa de suicidio fue un conflicto interpersonal (52%). La categoría de medicamentos usada más a menudo para el envenenamiento fue la de los analgésico (52%), siendo el acetaminofén el más común (26.2%). CONCLUSIÓN: Estos hallazgos se corresponden con las tendencias mundiales al suicidio y apuntan a una urgente necesidad de desarrollar e implementar medidas nacionales para la prevención y el tratamiento para grupos conocidos por hallarse en riego de intentos suicidas.

Preference of patient information leaflets over standard drug monographs by patients prescribed hydrochlorothiazide, nifedipine and enalapril / Preferencia por los prospectos de información al paciente en lugar de las monografías estándar sobre medicamentos, por parte de los pacientes a quienes se les ha prescrito hidroclorotiazida, nifedipina y analapril

Standard drug monographs (SDMs) have been described as deficient in providing information in a manner simplified enough for patient reading. The aim of this study was to design patient information leaflets for hydrochlorothiazide, nifedipine and enalapril with content indicated by patients as relevant and to evaluate them against the SDM.

We conclude that there is benefit in designing information leaflets that simplify language and medication information contained in SDMs, including better understanding of precautions to take while on medication and when to consult physicians.

Las monografías de medicamentos estandarizadas se han considerado deficientes a la hora de proporcionar información de manera suficientemente simple para que el paciente pueda entenderlas. El objetivo de este estudio fue disenar prospectos con información sobre la hidroclorotiazida, la nifedipina y el analapril con contenidos indicados como relevantes por los pacientes, y evaluarlos en comparación con las monografías estandarizadas de medicamentos (MEM). El prospecto de información para el paciente (PIP) fue disenado de modo que apareciera información sobre el nombre del medicamento, su uso, modo de operar, manera de tomarse, efectos secundarios comunes, almacenamiento, qué hacer en caso de perder una dosis, cosas que deben evitarse, y cuando debe contactarse el médico. Se evaluó la adecuación por parte de 10 farmacéuticos practicantes. Para cada medicamento, se reclutaron 40 pacientes, a 20 de los cuales se les dio monografías (MEM), en tanto que a 20 se les ofreció prospectos (PIP). El conocimiento de cada participante se examinó antes y después de la exposición a MEM o PIP, así como la opinión en cuanto a facilidad de lectura y grado de atracción, usando el análisis del Chi-cuadrado de Pearson. Los resultados mostraron que tanto MEM como PIP mejoraron el conocimiento sobre los efectos secundarios comunes, cuando se hacía una comparación con las respuestas antes de la exposición (χ² = 24.26para MEMy 27.64para PIP, p < 0.001) sin diferencia entre los grupos. Los encuestados que recibieron prospectos pudieron recordar mejor las "cosas a evitar" luego de la exposición a PIP (χ² =10.85, p < 0.001). Después de la exposición a MEM o PIP, los encuestados con PIP tenían mayor conciencia en cuanto a cuando contactar a un médico, en comparación con el grupo MEM (χ² = 8.41, p < 0.01). Cuando se les comparó con el grupo MEM, los encuestados que recibieron PIP mostraron por una parte mayor probabilidad de indicar que PIP era más fácil de leer (χ² = 20.00, p < 0.001) y atractivo (χ² = 12.45, p < 0.001), y por otra, una mayor tendencia a recomendar la distribución de su material de lectura a otros pacientes (χ² = 22.11, p < 0.001). Se llegó a la conclusión de que es beneficioso disenar prospectos que simplifiquen el lenguajey la información médica contenida en las monografias estándar del medicamento, incluyendo una mejor comprensión de las precauciones a tomar mientras se está bajo medicación, y sobre cuándo consultar al médico.

The antimicrobial screening of a Barbadian medicinal plant with indications for use in the treatment of diabetic wound infections.

OBJECTIVE: Diabetes mellitus is a chronic non-communicable disease with high prevalence in the North American and Caribbean region. Diabetic Foot Syndrome which is an associated complication can lead to the development of wounds and ulcers which can become infected. Justicia secunda, a plant known locally in Barbados as Bloodroot used in folklore for wound healing, was selected to test its ability to aid diabetic wound healing by antimicrobial activity. It was therefore tested against the bacteria Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, and Enterococcus feacalis (clincal strain) which are commonly found in diabetic wounds. METHODS: The plant was collected by local users. Methanol and acetone extracts of the plant were prepared with use of soxhlet extraction. The antimicrobial activity was assessed with the use of a modified Kirby-Baurer method. Concentrations of 200 mg/ml, 100 mg/ml, 10 mg/ml, and 1 mg/ml of the extract were used, with a standard ciprofloxacin 5 microg positive control, and a 5% dimethyl sulfoxide (DMSO) solution negative control. RESULTS: The J secunda methanol and acetone extracts with an extraction yield of 15.3% and 0.75%, respectively yielded no activity within the concentration range against the three strains of bacteria tested. In comparison with the positive control, relative inhibition zone diameter (RIZD) values of 0% resulted for both the negative control and the extracts, with the positive control having a value of 100%. CONCLUSION: The in vitro screen of the extracts prepared from J secunda, yielded no antimicrobial activity against the three strains of bacteria tested and therefore does not support the folklore claims by this mechanism of action.

Improvement in HDL cholesterol in postmenopausal women supplemented with pumpkin seed oil: pilot study.

OBJECTIVE: Pumpkin seed oil is rich in phytoestrogens and animal studies suggest that there is some benefit to supplementation in low estrogen conditions. This study is the first to evaluate the benefit of pumpkin seed oil in postmenopausal women. METHODS: This pilot study was randomized, double-blinded and placebo-controlled. Study participants included 35 women who had undergone natural menopause or had iatrogenically entered the climacteric due to surgery for benign pathology. Wheat germ oil (placebo; n = 14) and pumpkin seed oil (n = 21) were administered to eligible participants over a 12-week period at a dose of 2 g per day. Serum lipids, fasting plasma glucose and blood pressure were measured and an 18-point questionnaire regarding menopausal symptoms was administered; the atherogenic index was also calculated. Differences between groups, as well as before and after the period of supplementation, were evaluated with Student's t-test, Wilcoxon matched-pair signed-ranked test and Mann-Whitney test, as appropriate (Stata version 10.1). RESULTS: Women receiving pumpkin seed oil showed a significant increase in high density lipoprotein cholesterol concentrations (0.92 ± 0.23 mmol/l vs. 1.07 ± 0.27 mmol/l; p = 0.029) and decrease in diastolic blood pressure (81.1 ± 7.94 mmHg vs. 75.67 ± 11.93 mmHg; p < 0.046). There was also a significant improvement in the menopausal symptom scores (18.1 ± 9.0 vs. 13.2 ± 6.7; p < 0.030), with a decrease in severity of hot flushes, less headaches and less joint pains being the main contributors. Women in the group receiving wheat germ oil reported being more depressed and having more unloved feeling. CONCLUSION: This pilot study showed pumpkin seed oil had some benefits for postmenopausal women and provided strong evidence to support further studies.

Pharmacovigilance: healthcare professionals' role in benefits versus harm analysis of drugs use.

Monitoring the negative effect of drugs is a concept that all healthcare professionals would be aware of as part of their professional responsibility. However since 1968, it has evolved into a structured science called 'Pharmacovigilance'. This review aims to sensitize Caribbean healthcare professionals to the global pharmacovigilance network of the World Health Organization and how their active involvement at the national level is imperative to the benefit versus harm evaluation of drugs.

Hypoglycaemic complications with diabetes mellitus management: the predominant adverse drug reaction presenting to the accident and emergency department of the University Hospital of the West Indies / Complicaciones hipoglicémicas en el tratamiento de la diabetes mellitus: las reacciones adversas a los medicamentos que de manera predominante se presentan en la división de accidentes y emergencias del Hospital Universitario de West Indies

Evaluation of adverse drug reactions (ADRs) is important to the assessment of risk factors in an aim to ensure maximum benefits of drug therapy. This study was done to assess the types of ADRs presenting to the Accident and Emergency department (A&E) of the University Hospital of the West Indies. Admissions to the A&E associated with drugs were followed on a weekly basis for 19 weeks from October 2007 to February 2008 using the patient logbook. Medical records of patients with suspected ADRs were collected and evaluated by an Emergency Medicine Consultant of A&E to confirm the occurrence of ADRs and the suspected drug. Of the 8170 admissions to A&E, 48 (0.6%) were related to ADRs, with most occurring in females and the mean age (± standard error) was 58.9 (± 3.4) years. Drug induced hypoglycaemia accounted for 28 (56.3%) cases of ADRs and included mainly patients on insulin, with or without a sulphonylurea therapy. Most of these diabetic patients also had co-morbidities and were on multi-drug therapy (18). Allergic reactions accounted for 10 (21%) of the ADR outcomes. Other drugs accounting for ADRs included cardiovascular drugs (10.4%), analgesic/anti-inflammatory medications (8.3%), drugs acting on the central nervous system (8.3%) and anti-infectives (8.3%). It is concluded that drug-induced hypoglycaemia is the major ADR presenting to the A&E of the University Hospital of the West Indies; it is a preventable ADR and therefore further investigation should evaluate possible factors attributed to the occurrences.

La evaluación de reacciones adversas a los medicamentos (RAMs) es importante a la hora de evaluar los factores de riesgo con el objeto de asegurar beneficios máximos con la terapia medicamentosa. Este estudio fue realizado con el propósito de evaluar los tipos de RAMs que se presentan en la División de Accidentes y Emergencias (DAE) del Hospital Universitario de West Indies. Los ingresos al DAE asociados con medicamentos, fueron seguidos de forma hebdomadaria por un período de 19 semanas, desde octubre de 2007 hasta febrero de 2008, usando el libro de registro de pacientes. Las historias clínicas de los pacientes sospechosos de RAMs fueron recogidas y evaluadas por un Consultante de Medicina de Emergencia del DAE con el fin de confirmar que se trataba en efecto de un caso de RAM y verificar el medicamento de sospecha. De los 8170 ingresos al DAE, 48 (0.6%) guardaban relación con RAMs, siendo el caso que la mayor parte ocurrió con hembras y la edad promedio (± error estándar) fue 58.9 (± 3.4) años. La hipoglicemia inducida por medicamento representó 28 (56.3%) casos de RAMs e incluyó principalmente a pacientes bajo el uso de insulina, con o sin una terapia sulfonilurea. La mayoría de estos pacientes diabéticos también presentaban co-morbosidades y estaban bajo terapia multi-medicamentosa (18). Las reacciones alérgicas representan 10 (21%) de los resultados de ADR. Otros medicamentos causantes de RAMs incluyeron los medicamentos cardiovasculares (10.4%), los analgésicos/anti-inflamatorios (8.3%), los medicamentos que actúan sobre el sistema nervioso central (8.3%) y los anti-infecciosos (8.3%). Se concluye que la hipoglicemia inducida por medicamento es la RAM mayor que se presenta al DAE del Hospital Universitario de West Indies. Se trata de una RAM prevenible, y por ende las investigaciones ulteriores deben evaluar los posibles factores responsables de estas ocurrencias.

Pharmacovigilance: healthcare professionals' role in benefits versus harm analysis of drugs use / La vigilancia farmacológica: el papel de los profesionales del cuidado de la salud en el análisis de los beneficios versus riesgos de los medicamentos: análisis del uso de los medicamentos

This review aims to sensitize Caribbean healthcare professionals to the global pharmacovigilance network of the World Health Organization and how their active involvement at the national level is imperative to the benefit versus harm evaluation of drugs.

El monitoreo de los efectos negativos de los medicamentos es un concepto del cual todos los profesionales del cuidado de la salud debían tener conciencia como parte de su responsabilidad profesional. Desde 1968, este monitoreo se ha venido transformando en una ciencia estructurada conocida como "Vigilancia farmacológica", o "farmacovigilancia". El presente examen se dirige a sensibilizar a los profesionales del cuidado de la salud caribeños con la red de vigilancia farmacológica global de la Organización Mundial de la Salud, y a que tomen conciencia de cómo su participación activa a nivel nacional es indispensable para la evaluación de los beneficios y riesgos de los medicamentos.

Admissions to the A&E associated with drugs were followed on a weekly basis for 19 weeks from October 2007 to February 2008 using the patient logbook. Medical records of patients with suspected ADRs were collected and evaluated by an Emergency Medicine Consultant of A & E to confirm the occurrence of ADRs and the suspected drug. Of the 8170 admissions to A&E, 48 (0.6%) were related to ADRs, with most occurring in females and the mean age (+/- standard error) was 58.9 (+/- 3.4) years. Drug induced hypoglycaemia accounted for 28 (56.3%) cases of ADRs and included mainly patients on insulin, with or without a sulphonylurea therapy. Most of these diabetic patients also had co-morbidities and were on multi-drug therapy (18). Allergic reactions accounted for 10 (21%) of the ADR outcomes. Other drugs accounting for ADRs included cardiovascular drugs (10.4%), analgesic/anti-inflammatory medications (8.3%), drugs acting on the central nervous system (8.3%) and anti-infectives (8.3%). It is concluded that drug-induced hypoglycaemia is the major ADR presenting to the A&E of the University Hospital of the West Indies; it is a preventable ADR and therefore further investigation should evaluate possible factors attributed to the occurrences.

Supplementation with pumpkin seed oil improves plasma lipid profile and cardiovascular outcomes of female non-ovariectomized and ovariectomized Sprague-Dawley rats.

Pumpkin (Cucurbita species) seed oil (PSO) is a rich source of phytoestrogens and the aim of this study was to examine the effect of PSO supplementation on the total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), triglycerides, high density lipoprotein cholesterol (HDL-C), systolic and diastolic blood pressure in non-ovariectomized and ovariectomized Sprague-Dawley rats. Female rats weighing 220-300 g were divided into non-ovariectomized rats for supplementation with corn oil (control CO; n = 6) or PSO (control PSO; n = 5) and ovariectomized rats for supplementation with corn oil (OVX/CO; n = 6) or PSO (OVX/PSO; n = 5) for 5 days per week for 12 weeks (corn oil 40 mg/kg or PSO 40 mg/kg given orally). Systolic and diastolic blood pressures were measured weekly. Blood was collected at the end of the period for plasma lipid assays. Control PSO had lower TC, LDL-C, triglycerides and higher HDL-C than the control CO. The OVX/CO had higher TC, LDL-C, triglycerides and lower HDL-C than the control CO and these changes were prevented in the OVX/PSO rats. PSO supplementation also resulted in lower systolic and diastolic blood pressures in both non-ovariectomized and ovariectomized rats. It is concluded that PSO supplementation can prevent changes in plasma lipids and blood pressure associated with inadequate oestrogen availability.

Generic substitutions: a 2005 survey of the acceptance and perceptions of physicians in Jamaica / Sustituciones genéricas: una encuesta del 2005 sobre la aceptación y percepciones de los médicos en Jamaica

In Jamaica, the 1993 amendment to the Pharmacy Act allows pharmacists to offer patients generic substitutions for innovator brands; however, there were reservations among physicians about this policy implementation. The success of the amendment may be influenced by the confidence of physicians in the therapeutic equivalence of generics, especially since the act also allows physicians to indicate [quot ]no substitution[quot ] on prescriptions. The aim of this investigation was to examine the current attitudes of physicians towards the use of generic substitutions. One hundred questionnaires were distributed island-wide among physicians of varying specialities, with items to characterize their demographics and specific statements to determine their perception of generics. Sixty questionnaires were returned completed (60% response). Most of the responding physicians were males (2:1 male:female ratio); the majority were general/family medicine physicians in private practice. Forty-nine per cent of the responding physicians were mostly prescribing generic brands willingly, indicating that the cheaper cost of generic substitutes was a significant factor for this trend. There were doubts about whether bioequivalence of a generic was equitable to therapeutic equivalence to innovator drug. Additionally, 33% of the physicians were able to identify at least one case in the past year of clinical problems with generic substitutes that they perceived would not have occurred with the innovator. It is concluded that while the amendment to the Pharmacy Act encourages the substitution of generics in preference to innovator brands, more emphasis should be placed on improving physician confidence in the therapeutic equivalence of generics.

En Jamaica, la enmienda de 1993 a la Ley de Farmacia permite al farmacéutico ofrecer a los pacientes sustituciones genéricas para las marcas innovadoras. Sin embargo, había reservas entre los médicos acerca de la implementación de esta política. El éxito de la enmienda puede ser influido por la confianza de los médicos en la equivalencia terapéutica de los genéricos, sobre todo porque la ley también permite a los médicos indicar en las prescripciones que no ha de usarse "ninguna sustitución". El objetivo de esta investigación fue examinar las actitudes actuales de los médicos hacia el uso de sustituciones genéricas. Se distribuyeron cien encuestas por toda la isla entre médicos de distintas especialidades, con puntos en los que se pedía caracterizar sus demografías, y hacer declaraciones específicas a fin de determinar su percepción de los genéricos. Sesenta encuestas regresaron totalmente respondidas (60% de respuesta). La mayoría de los médicos que respondieron eran hombres (proporción 2:1 hombre/mujer); en la mayor parte de los casos se trataba de doctores de medicina general, o de familia que ejercían de forma privada. El cuarenta y nueve por ciento de los médicos encuestados dijeron prescribir principalmente marcas genéricas, indicando por voluntad propia que el menor costo de los sustitutos genéricos era un factor significativo para esta tendencia. Había dudas sobre si la bio-equivalencia de un genérico era equiparable a la equivalencia terapéutica con respecto al medicamento de innovación. Además, 33% de los médicos pudieron identificar al menos un caso en el último año de problemas clínicos con los sustitutos genéricos, lo cual según su percepción no habría ocurrido con el innovador. Se concluye que si bien la Ley de Farmacia estimula la preferencia de la sustitución de genéricos por encima de las marcas innovadoras, debe hacerse más énfasis en mejorar la confianza del médico en la equivalencia terapéutica de los genéricos.
