Impact of the 2010 resuscitation guidelines training on layperson chest compressions / 世界急诊医学杂志（英文）

@#BACKGROUND: Survival from cardiac arrest is sensitive to the quality of delivered CPR. In 2010, updated international resuscitation guidelines emphasized deeper chest compressions and faster rates, yet it is unknown whether training laypersons using updated guidelines resulted in changed CPR performance. We hypothesized that laypersons taught CPR using the 2010 guidelines performed deeper and faster compressions than those taught using the 2005 materials. METHODS: This work represents a secondary analysis of a study conducted at eight hospitals where family members of hospitalized cardiac patients were trained in CPR. An initial cohort was trained using the 2005 guidelines, and a subsequent cohort was trained using the 2010 guideline materials. Post training, CPR skills were quantified using a recording manikin. RESULTS: Between May 2009 to August 2013, 338 subjects completed the assessment. Among the subjects, 176 received 2005 training and 162 underwent 2010 training. The mean compression rate in the 2005 cohort was 87 (95％CI 83–90) per minute, and in the 2010 cohort was 86 (95％CI 83–90) per minute (P=ns), while the mean compression depth was 34 (95％CI 32–35) mm in the 2005 cohort and 46 (95％CI 44–47) mm in the 2010 cohort (P<0.01). CONCLUSIONS: Training with the 2010 CPR guidelines resulted in a statistically significant increase in trainees' compression depth but there was no change in compression rate. Nevertheless, the majority of CPR performed by trainees in both cohorts was below the guideline recommendation, highlighting an important gap between training goals and trainee performance.

8 años de cápsula endoscopica: progresos y retos / 8 years of capsule endoscopy: progresses and challenges

Desde su introducción en el año 2001, la cápsula endoscópica (CE) ha cambiado el diagnóstico y manejo de la patología del intestino delgado. Evaluar la utilidad clínica de la CE en pacientes con sospecha de enfermedad de intestino delgado. Pacientes a quienes se les realizó CE desde octubre 2001 hasta abril 2009 en dos centros médicos: La Policlínica Metropolitana y el Centro Médico de Caracas. Cápsulas utilizadas: M2A y PillCam SB (Given Imaging). Se registraron datos demográficos, indicaciones, vaciamiento gástrico y tránsito intestinal, hallazgos y complicaciones. 339 pacientes, 180 hombres-159 mujeres. Edad promedio: 56,04 años. Indicaciones: hemorragia digestiva oscura (n=217), diarrea crónica (n=22), enfermedad de Crohn (20), búsqueda de tumores (n=30), dolor abdominal (n=29), enfermedad celíaca (n=5), misceláneos (n=16). Se encontraron lesiones en 78,8% de los pacientes. Hallazgos: angiectasias 28,3%, erosiones 28,6%, úlceras 12,5%, sangrado activo 8% y tumores subepiteliales 4,2%. Al correlacionar los hallazgos con las indicaciones se encontró un porcentaje de concordancia significativo en pacientes con hemorragia digestiva oscura y enfermedad de Crohn. Complicaciones: obstrucción intestinal (n=1), retención (n=6). La CE es un método mínimamente invasivo, bien tolerado, con pocas complicaciones y porcentaje elevado de detección de lesiones, que parece posicionarse para guiar el diagnóstico y tratamiento de patologías como el sangrado digestivo oscuro y la enfermedad de Crohn. Pudimos adaptarnos a la plataforma tecnológica como usuarios y prepararnos para los nuevos avances que se avecinan, creemos que es el momento para dar inicio a un programa de entrenamiento en CE...

Since its introduction in 2001, the endoscopic capsule (EC) has changed the diagnosis and management of small bowel pathology. Objective: To evaluate the clinical benefi t of EC in patients with suspected small bowel disease. Patients who underwent EC from October 2001 to April 2009 at two medical centers, Policínica Metropolitana and Centro Médico de Caracas. Capsules used: M2A and PillCam SB (Given Imaging). Demographic data, indications, gastric emptying and intestinal transit, as well as, fi ndings and complications were recorded. 339 patients, 180 men, 159 women. Average age: 56.04 yearsold. Indications: obscure gastrointestinal bleeding (n = 217), chronic diarrhea (n = 22), Crohn’s disease (n=20), tumor screening (n = 30), abdominal pain (n = 29), celiac disease (n = 5), miscellaneous (n = 16). Lesions were found in 78.8% of patients. Findings: angiectasias 28.3%, erosions 28.6%, ulcers 12.5%, active bleeding 8% and, subepithelial tumors 4.2%. By correlating the fi ndings with the indications we found a signifi cant percentage of concordance in patients with obscure gastrointestinal bleeding and Crohn’s disease. Complications: intestinal obstruction (n=1), retention (n=6). EC is a minimally invasive well tolerated method, with few complications and high percentage of lesions detection, which seems to be positioned to guide the diagnosis and therapy of disorders such as, obscure gastrointestinal bleeding and Crohn’s disease. We were able to adapt to the technological platform as users and prepare for new developments to come; we believe it is time to begin a training program in EC...

Cultivation of medicinal plants in alley cropping systems with Moringa oleifera in the Virgin Islands

Medicinal and aromatic plants (MAPs) are horticultural crops with socio-economic significance in the Caribbean. People of the Caribbean maintain the tradition of making 'bush (herb) teas' as part of their daily activity. 'Bush tea' is made with a variety of herbs that are combined for their culinary and medicinal properties. Cultivating these plants complements conventional fruit and vegetable production in the Virgin Islands and enhance small-farm productivity. This study was initiated to evaluate the agronomic and economic potential of agroforestry systems involving MAPs with focus on alley cropping. Field experiments were conducted to determine yield and productivity of popular species of medicinal plants and aromatic herbs commonly used in the Virgin Islands. Medicinal plants included 'inflammation bush' (Verbesina alata), 'worrywine' (Stachytarpheta jamaicensis) and 'japana' (Eupatorium triplinerve) ... Data were collected on fresh and dry matter yield ... Results indicated yield of intercropped medicinal plants and herbs were not significantly reduced during the first harvest, but yield tended to decrease in subsequent harvest suggesting that tree-crop competition was minimal during the early establishment stage
