RESUMEN

Ulcerative colitis is an idiopathic chronic inflammatory disease of the colon for which a lot of treatment modalities are present. However, significant side effects are associated with them, and there is a need for a search for other tretment options. This study was aimed to assess the contribution of niclosamide in experimentally established colitis in rats. Animals were categorized into 5 groups; the control group undergoes no induction of UC, colitis group in which UC was induced, and animals receive no treatment, the niclosamide group that received niclosamide and sulfasalazine group that received sulfasalazine. Each group was composed of 10 animals. After the completion of a one-month period of the experiment animals were sacrificed and the following meausres were done: the weight of the colon, determination of the area of mucosal damage by mm2, histological scoring after hematoxylin and eosin stain together with MAC score and immunohistochemistry of IL-6, TNF-alpha, MPO, MDA, CD62, and ICAM1. The results of the current study revealed that Nicosamide was able to reduce the area of mucosal damage, colon weight, histological and Mac scores and immunohistochemical scores of inflammatory and oxidative markers, significantly when contrasted to a group of colitis (P< 0.05). It has been concluded that Niclosamide was proved to have a significant effect as an adjuvant mode of therapy for colitis through its, anti-inflamatory and anti-oxidant effects (AU)

RESUMEN

Loeffler endocarditis is a complication of hypereosinophilic syndrome resulting from eosinophilic infiltration of heart tissue. We report a case of Loeffler endocarditis in which three-dimensional transthoracic and transesophageal echocardiography provided additional information to what was found by two-dimensional transthoracic echocardiography alone. Our case illustrates the usefulness of combined two- and three-dimensional echocardiography in the assessment of Loeffler endocarditis. In addition, a summary of the features of hypereosinophilic syndrome and Loeffler endocarditis is provided in tabular form.

RESUMEN

OBJECTIVES: The rate of unplanned ICU readmissions is often considered a measure of hospital performance. However, the degree to which these readmissions are preventable and the causes of preventable readmissions are unknown, creating uncertainty about the feasibility and value of reducing ICU readmission rates. To inform this issue, we sought to determine the frequency and underlying causes of potentially preventable ICU readmissions. DESIGN: Retrospective cohort study. SETTING: Urban, academic medical center in the mid-Atlantic United States. PATIENTS: Adult patients discharged alive from their first ICU admission with an unplanned readmission within 48 hours of discharge. MEASUREMENTS AND MAIN RESULTS: Each patient's medical chart was reviewed by two independent investigators who rated each readmission's preventability according to standardized scale and assessed the etiology of both preventable and nonpreventable readmissions. We assessed concordance between raters using the κ statistic and resolved disagreements through iterative discussion. Of 136 readmissions in the final analysis, 16 (11.8%; 95% CI, 6.9-18.4) were considered preventable and 120 (88.2%; 95% CI, 81.5-93.1) were considered nonpreventable. Of nonpreventable readmissions, 67 were due to a new clinical problem and 53 were due to an existing clinical problem. Among preventable readmissions, six were attributable to system errors, six were attributable to management errors, two were attributable to procedural events, one was attributable to a diagnostic error, and one was attributable to a medication error. Compared to nonpreventable readmissions, preventable readmissions tended to have shorter index ICU lengths of stay (2 vs 3 d; p = 0.05) and a shorter duration of time on the ward prior to readmission (16.6 vs 23.6 hr; p = 0.05). CONCLUSIONS: The majority of early ICU readmissions are nonpreventable, raising important concerns about ICU readmission rates as a measure of hospital performance.

RESUMEN

OBJECTIVES: To identify CVD risk factors present in patients presenting with stroke; to assess knowledge of patients on risk factors for CVD; and to identify management methods employed (prior to admission) by patients to deal with these risk factors. DESIGN AND METHODS: This study used a cross-sectional, incident case design. All patients admitted to the hospital, within a 6 week period, given an initial diagnosis of stroke by the attending physician, were eligible for the study. Patients were recruited using consecutive sampling. Data on patient risk awareness and management methods were gathered using a survey. Data on risk factors present in patients were collected using patient records. RESULTS: A total of 102 patients were interviewed. The two major risk factors present in patients were hypertension (80.2%) and diabetes (57.8%). 83.3% of patients identified hypertension as a risk factor and 78.8% identified diabetes. However, 32.2% of hypertensive patients and 40.5% of diabetics reported not taking medication despite being awareness of their risk. Similarly 81.3% of patients knew lack of exercise was a risk factor, but only half were exercising frequently in the past 2 years. CONCLUSION: In this study, hypertension and diabetes were found to be the two major risk factors present in stroke patients. While patient knowledge about risk factors was high, their management of their risk factors as well as general knowledge about stroke prevention were lacking. This could be helpful in formulating public health strategy, if supported by larger population based studies.

RESUMEN

OBJECTIVES: To evaluate the evidence base used in policy and healthcare decision making by the Regional Health Authorities in Trinidad. DESIGN AND METHODS: The study focused on the five Regional Health Authorities (RHAs) in Trinidad where senior administrative employees at each Regional Health Authority were purposively sampled and interviewed using a structured questionnaire. Responses were initially reviewed individually to determine types of evidence used within each RHA. All responses were secondly compared between the various RHAs. RESULTS: All RHAs participated; each had an observatory type unit which was responsible for data collection, collation and production of reports on an annual basis. Reports focused on the number of patients accessing services (e.g. specialist clinics and surgical procedures), patient demographics and patient access to health services. All RHAs had annual service agreements with the Ministry of Health which acted as a guide with targets and as a check on accountability of money spent. Decision making in each RHA was tiered by financial cap; most decisions were made by the Chief Executive Officer and/or Board of Directors within their caps; decisions requiring monetary investment over the RHA limit had to be approved by the Ministry of Health. CONCLUSION: This study revealed that RHAs had systems in place whereby they engaged in evidence-based practice utilising the Authority’s observatory data plus other information sources, ran trial periods and economic analyses for healthcare related decision making.

RESUMEN

The aim of this study was to determine the critical incidents that contribute to the initiation of substance use and abuse among women in Trinidad and Tobago. Twenty women were randomly selected from 46 women currently attending 43 drug rehabilitation centres, Narcotics Anonymous and Alcoholics Anonymous groups in Trinidad and Tobago. In-depth semi-structured interviews using the critical incident technique were conducted. Interviews were recorded, transcribed and analyzed. Concepts, categories and themes were determined by team study and group discussion. The critical incidents that influenced women to initiate the use and abuse of substances fell into eight major themes: factors intrinsic to the individual woman, family factors, social and environmental factors, life stresses, relationship issues, abuse, peer pressure and substance use and abuse as a coping mechanism. The results imply that the factors contributing to the initiation of substance use and abuse among women in Trinidad and Tobago are many and complex. As such any attempt to address this issue requires a broad-based approach. Such an approach should address family use of such substances, societal acceptance of them, availability, the self-esteem of the individual woman and her ability to cope with peer and internal stresses.

El objetivo de este estudio era determinar los incidentes críticos que contribuyen a la iniciación en el uso yabuso de substancias entre las mujeres en Trinidad y Tobago. Se seleccionaron veinte mujeres al azar, de46 mujeres que asistían a 43 centros de rehabilitación de drogas, grupos de Alcohólicos Anónimos, y Narcóticos Anónimos en Trinidad y Tobago. Se realizaron entrevistas profundas semi- structuradas usando la técnica de incidentes críticos. Las entrevistas fueron grabadas, transcriptas, y analizadas. Los conceptos, categorías y temas fueron determinados mediante estudio en equipo y discusión en grupos. Los incidentes críticos que influyeron en que las mujeres se iniciaran en el uso y abuso de substancias comprendían ocho temas principales: factores intrínsecos a la mujer como individuo, factores familiares, factores sociales y medioambientales, estreses cotidianos, problemas en las relaciones, abusos, influencia de los amigos y malas compañías, y el uso y abuso de sustancias como mecanismo para hacer frente al estrés. Los resultados implican que los factores que contribuyen a la iniciación del uso y abuso de sustancias entre las mujeres de Trinidad y Tobago son muchos y complejos. Siendo así, cualquier intento por abordar este problema requiere un enfoque amplio. Tal enfoque debe abordar el uso de substancias por parte de la familia, la aceptación social de las substancias, la disponibilidad, la autoestima de la mujer como individuo y su capacidad para hacer frente tanto a su estrés interno como al que proviene de la presión que ejercen amigos y malas compañías.
