ABSTRACT
Cardiovascular imaging is exponentially increasing in the diagnosis, risk stratification, and therapeutic management of patients with cardiovascular disease. The European Society of Cardiovascular Radiology (ESCR) is a non-profit scientific medical society dedicated to promoting and coordinating activities in cardiovascular imaging. The purpose of this paper, written by ESCR committees and Executive board members and approved by the ESCR Executive Board and Guidelines committee, is to codify a standardized approach to creating ESCR scientific documents. Indeed, consensus development methods must be adopted to ensure transparent decision-making that optimizes national and global health and reaches a certain scientific credibility. ESCR consensus documents developed based on a rigorous methodology will improve their scientific impact on the management of patients with cardiac involvement. CRITICAL RELEVANCE STATEMENT: This document aims to codify the methodology for producing consensus documents of the ESCR. These ESCR indications will broaden the scientific quality and credibility of further publications and, consequently, the impact on the diagnostic management of patients with cardiac involvement. KEY POINTS: Cardiovascular imaging is exponentially increasing for diagnosis, risk stratification, and therapeutic management. The ESCR is committed to promoting cardiovascular imaging. A rigorous methodology for ESCR consensus documents will improve their scientific impact.
ABSTRACT
Measurements of net primary productivity (NPP) and litter decomposition from tropical peatlands are severely lacking, limiting our ability to parameterise and validate models of tropical peatland development and thereby make robust predictions of how these systems will respond to future environmental and climatic change. Here, we present total NPP (i.e., above- and below-ground) and decomposition data from two floristically and structurally distinct forested peatland sites within the Pastaza Marañón Foreland Basin, northern Peru, the largest tropical peatland area in Amazonia: (1) a palm (largely Mauritia flexuosa) dominated swamp forest and (2) a hardwood dominated swamp forest (known as 'pole forest', due to the abundance of thin-stemmed trees). Total NPP in the palm forest and hardwood-dominated forest (9.83 ± 1.43 and 7.34 ± 0.84 Mg C ha-1 year-1, respectively) was low compared with values reported for terra firme forest in the region (14.21-15.01 Mg C ha-1 year-1) and for tropical peatlands elsewhere (11.06 and 13.20 Mg C ha-1 year-1). Despite the similar total NPP of the two forest types, there were considerable differences in the distribution of NPP. Fine root NPP was seven times higher in the palm forest (4.56 ± 1.05 Mg C ha-1 year-1) than in the hardwood forest (0.61 ± 0.22 Mg C ha-1 year-1). Above-ground palm NPP, a frequently overlooked component, made large contributions to total NPP in the palm-dominated forest, accounting for 41% (14% in the hardwood-dominated forest). Conversely, Mauritia flexuosa litter decomposition rates were the same in both plots: highest for leaf material, followed by root and then stem material (21%, 77% and 86% of mass remaining after 1 year respectively for both plots). Our results suggest potential differences in these two peatland types' responses to climate and other environmental changes and will assist in future modelling studies of these systems.
Mediciones de la productividad primaria neta (PPN) y la descomposición de materia orgánica de las turberas tropicales son escasas, lo que limita nuestra capacidad para parametrizar y validar modelos de desarrollo de las turberas tropicales y, en consecuencia, realizar predicciones sólidas sobre la respuesta de estos sistemas ante futuros cambios ambientales y climáticos. En este estudio, presentamos datos de PPN total (es decir, biomasa aérea y subterránea) y descomposición de la materia orgánica colectada en dos turberas boscosas con características florísticas y estructurales contrastantes dentro de la cuenca Pastaza Marañón al norte del Perú, el área de turberas tropicales más grande de la Amazonia: (1) un bosque pantanoso dominado por palmeras (principalmente Mauritia flexuosa) y (2) un bosque pantanosos dominado por árboles leñosos de tallo delgado (conocido como 'varillal hidromórfico'). La PPN total en el bosque de palmeras y el varillal hidromórfico (9,83 ± 1,43 y 7,34 ± 0,84 Mg C ha1 año1 respectivamente) fue baja en comparación con los valores reportados para los bosques de tierra firme en la región (14,2115,01 Mg C ha1 año1) y para turberas tropicales en otros lugares (11,06 y 13,20 Mg C ha1 año1). A pesar de que la PPN total fue similar en ambos tipos de bosque, hubo diferencias considerables en la distribución de la PPN. La PPN de las raíces finas fue siete veces mayor en el bosque de palmeras (4,56 ± 1,05 Mg C ha1 año1) que en el varillal hidromórfico (0,61 ± 0,22 Mg C ha1 año1). La PPN de la biomasa aérea de las palmeras, un componente ignorado frecuentemente, contribuyó en gran medida a la PPN total del bosque de palmeras, representando el 41% (14% en el varillal hidromórfico). Por el contrario, la tasa de descomposición de materia orgánica de Mauritia flexuosa fue la misma en ambos sitios: la más alta corresponde a la hojarasca, seguida por las raíces y luego el tallo (21%, 77% y 86% de la masa restante después de un año, respectivamente para ambos sitios). Nuestros resultados sugieren diferencias potenciales en la respuesta de estos dos tipos de turberas al clima y otros cambios ambientales, y ayudarán en futuros estudios de modelamiento de estos sistemas.

PURPOSE: We provide an initial description and validation of some public domain patient-reported outcome (PRO) items to assess cancer symptom burden to address immediate barriers to symptom assessment use in clinical practice and facilitate future research. METHODS: We created the Open Symptom Framework (OSF), a flexible tool for clinical cancer-related symptom assessment. The items comprise six components: recall period, concept, symptom, qualifier(s), a definition, and a 5-point Likert-type response. We recruited patients receiving cancer therapy in the United States and United Kingdom. We assessed external construct validity by comparing OSF scores to the PRO-CTCAE measure and assessed reliability, scalability, dimensionality, and item ordering within a non-parametric item response theory framework. We tested differential item functioning for country, age, gender, and level of education. RESULTS: We developed a framework alongside clinical and psychometric experts and debrieifed with 10 patients. For validation, we recruited 331patients. All items correlated with the PRO-CTCAE equivalents (r = 0.55-0.96, all p < 0.01). Mokken analysis confirmed the scalability and unidimensionality of all symptom scales with multiple items at the scale (Ho = 0.61-0.75) and item level (Hi = 0.60-0.76). Items are interpreted consistently between demographic groups (Crit = 0 for all groups). CONCLUSION: The public domain OSF has excellent psychometric properties including face, content, and criterion validity and can facilitate the development of flexible, robust measurements to fulfil stakeholder need. The OSF was designed specifically to support clinical assessment but will function well for research. Further work is planned to increase the number of symptoms and number of questions per symptom within the framework.
ABSTRACT
Six hundred and fifty-four inpatients who participated in a spiritual group therapy intervention provided qualitative feedback regarding what helped them and what could be improved. Patients revealed that enjoying a sense of connection with other people and a sense of openness in the groups and simply talking about spirituality with other people was helpful to them. Many group members requested that groups go on for a longer amount of time than 12 sessions, to have longer sessions, and to have more frequent meetings. In addition, members described improvements that could be made to the group, including members' being better screened, leaders preventing individual members from dominating discussions or from being quiet or leaving the group early, and members' wanting more structure as well as more open discussion. The findings highlight the importance of connection, openness, and spirituality when implementing spiritual group interventions in hospital settings. Implications for future research, training, and clinical interventions are discussed.

The photo-induced dynamics of o-nitrophenol, particularly its photolysis, has garnered significant scientific interest as a potential source of nitrous acid in the atmosphere. Although the photolysis products and preceding photo-induced electronic structure dynamics have been investigated extensively, the nuclear dynamics accompanying the non-radiative relaxation of o-nitrophenol on the ultrafast timescale, which include an intramolecular proton transfer step, have not been experimentally resolved. Herein, we present a direct observation of the ultrafast nuclear motions mediating photo-relaxation using ultrafast electron diffraction. This work spatiotemporally resolves the loss of planarity which enables access to a conical intersection between the first excited state and the ground state after the proton transfer step, on the femtosecond timescale and with sub-Angstrom resolution. Our observations, supported by ab initio multiple spawning simulations, provide new insights into the proton transfer mediated relaxation mechanism in o-nitrophenol.
ABSTRACT
OBJECTIVES: This study aimed to evaluate clinical signs, diagnostic findings, treatment administered and short- (survival to 28 days) and long-term prognosis (survival >6 months) in dogs diagnosed with trapped neutrophil syndrome. MATERIALS AND METHODS: Medical records of 12 dogs (10 Border Collies and two Border Collie Crossbreeds) homozygous for VPS13B gene mutation causing trapped neutrophil syndrome from seven veterinary institutions between January 2011 and June 2022 were evaluated retrospectively. RESULTS: The most common clinical signs at the time of diagnosis were pyrexia, abnormal gait and gastrointestinal signs. Concurrent metaphyseal osteopathy and immune-mediated polyarthritis were common. Seven dogs had a segmented neutrophil count below, four dogs within and one dog above the analyser reference interval at presentation. Two dogs had a septic source identified and both were additionally identified to be homozygous mutant positive on DNA testing by polymerase chain reaction (PCR) for canine cyclic neutropenia. All dogs received at least one antimicrobial agent and 10 dogs received treatment with prednisone or prednisolone (median starting dose 1 mg/kg/day; range 0.5 to 2.5 mg/kg/day). Nine dogs were alive at 28 days and six dogs were alive at 6 months post-diagnosis. CLINICAL SIGNIFICANCE: Trapped neutrophil syndrome should be suspected in young Border Collies with pyrexia, lameness and gastrointestinal signs. Neutropenia may not always be present and long-term survival is possible. A septic focus was not commonly identified in our population; however, our results suggest that if identified, testing for concurrent canine cyclic neutropenia should be considered.

It is well established that solutions of both polymeric and oligomeric κ-carrageenan exhibit a clear change in optical rotation (OR), in concert with gel-formation for polymeric samples, as the solution is cooled in the presence of certain ions. The canonical interpretation - that this OR change reflects a 'coil-to-helix transition' in single chains - has seemed unambiguous; the solution- or 'disordered'-state structure has ubiquitously been assumed to be a 'random coil', and the helical nature of carrageenan in the solid-state was settled in the 1970s. However, recent work has found that κ-carrageenan contains substantial helical secondary structure elements in the disordered-state, raising doubts over the validity of this interpretation. To investigate the origins of the OR, density-functional theory calculations were conducted using atomic models of κ-carrageenan oligomers. Changes were found to occur in the predicted OR owing purely to dimerization of chains, and - together with the additional effects of slight changes in conformation that occur when separated helical chains form double-helices - the predicted OR changes are qualitatively consistent with experimental results. These findings contribute to a growing body of evidence that the carrageenan 'disorder-to-order' transition is a cooperative process, and have further implications for the interpretation of OR changes demonstrated by macromolecules in general.
ABSTRACT
Sugarcane, the world's most harvested crop by tonnage, has shaped global history, trade and geopolitics, and is currently responsible for 80% of sugar production worldwide1. While traditional sugarcane breeding methods have effectively generated cultivars adapted to new environments and pathogens, sugar yield improvements have recently plateaued2. The cessation of yield gains may be due to limited genetic diversity within breeding populations, long breeding cycles and the complexity of its genome, the latter preventing breeders from taking advantage of the recent explosion of whole-genome sequencing that has benefited many other crops. Thus, modern sugarcane hybrids are the last remaining major crop without a reference-quality genome. Here we take a major step towards advancing sugarcane biotechnology by generating a polyploid reference genome for R570, a typical modern cultivar derived from interspecific hybridization between the domesticated species (Saccharum officinarum) and the wild species (Saccharum spontaneum). In contrast to the existing single haplotype ('monoploid') representation of R570, our 8.7 billion base assembly contains a complete representation of unique DNA sequences across the approximately 12 chromosome copies in this polyploid genome. Using this highly contiguous genome assembly, we filled a previously unsized gap within an R570 physical genetic map to describe the likely causal genes underlying the single-copy Bru1 brown rust resistance locus. This polyploid genome assembly with fine-grain descriptions of genome architecture and molecular targets for biotechnology will help accelerate molecular and transgenic breeding and adaptation of sugarcane to future environmental conditions.

Physical disability is a common component of post-intensive care syndrome, but the importance of musculoskeletal health in this population is currently unknown. We aimed to determine the musculoskeletal health state of intensive care unit survivors and assess its relationship with health-related quality of life; employment; and psychological and physical function. We conducted a multicentre prospective cohort study of adults admitted to intensive care for > 48 h without musculoskeletal trauma or neurological insult. Patients were followed up 6 months after admission where musculoskeletal health state was measured using the validated Musculoskeletal Health Questionnaire score. Of the 254 participants, 150 (59%) had a musculoskeletal problem and only 60 (24%) had received physiotherapy after discharge. Functional Comorbidity Index, Clinical Frailty Scale, duration of intensive care unit stay and prone positioning were all independently associated with worse musculoskeletal health. Musculoskeletal health state moderately correlated with quality of life, rs = 0.499 (95%CI 0.392-0.589); anxiety, rs = -0.433 (95%CI -0.538 to -0.315); and depression, rs = -0.537 (95%CI -0.631 to -0.434) (all p < 0.001). Patients with a musculoskeletal problem were less physically active than those without a problem (median (IQR [range]) number of 30 min physical activity sessions per week 1 (0-3.25 [0-7]) vs. 4 (1-7 [0-7]), p < 0.001, respectively). This study found that musculoskeletal health problems were common after intensive care unit stay. However, we observed that < 25% of patients received physical rehabilitation after discharge home. Our work has identified potential high-risk groups to target in future interventional studies.

En 1978, la Organización Mundial de la Salud definió la atención primaria de la salud como pilar fundamental de la salud global. En los últimos años, a las causas habituales de mortalidad (infecciosas, carenciales) se sumaron las provocadas por enfermedades crónicas y degenerativas. Es posible brindar atención de alta complejidad a pacientes sin recursos adecuados para su supervivencia luego del egreso. El sistema de salud no supo adaptarse a este cambio y mantuvo un modelo fragmentado, reactivo y centrado en la enfermedad.La "atención primaria selectiva" permite reorientar las bases de la atención primaria según las características de la población. Un grupo de acciones específicas, dirigidas a una población con vulnerabilidades particulares, potencia las virtudes de la atención primaria de la salud. Se describe el modelo de atención "Cuidados Especiales Ambulatorios Pediátricos" implementado en el Centro de Salud y Acción Comunitaria N.º 5 de la Ciudad de Buenos Aires
In 1978, the World Health Organization defined primary health care as the cornerstone of global health. In recent years, the usual causes of mortality (infections, deficiency diseases) now include chronic and degenerative diseases. It is now possible to provide tertiary care to patients without adequate resources for their survival after discharge. The health system has not been able to adapt to such change and has maintained a fragmented, reactive, disease-centered model."Selective primary care" is useful to redirect primary care bases according to the characteristics of the population. A set of specific measures, targeted at a population with specific vulnerabilities, leverages the power of primary health care. Here we describe the "Outpatient Pediatric Special Care" model of care implemented at the Center for Health and Community Action no. 5, in the Autonomous City of Buenos Aires.

Introducción: Los procesos migratorios han aumentado a nivel mundial por múltiples causas. En nuestro país un 4.5% de población es extranjera y el 69% proviene de países limítrofes. La ley de Migraciones N°25.871 garantiza el goce igualitario de derechos a migrantes extranjeros y argentinos. La comuna 8 (CABA) presenta 19.9% de población extranjera. Su primer Nivel de Atención está a cargo, entre otros, de los Centros de Salud y Acción Comunitaria N° 5 y 18. El Hospital Juan P. Garrahan es centro de derivación regional. El objetivo de la investigación fue describir las características de la respuesta del Sistema de Salud, específicamente, comparar el acceso al primer nivel de prevención y la satisfacción con la actividad asistencial entre familias migrantes extranjeras y nativas. Métodos: Estudio multicéntrico, observacional y de corte transversal a través de entrevistas semiestructuradas a familias migrantes extranjeras y nativas entre Julio 2014 y Junio 2015. Los resultados se expresaron en frecuencias y porcentajes en forma global y comparativa entre ambos grupos. Resultados: Se encuestaron 287 familias, 52% nativas y 48% migrantes extranjeras. Se encontró menor acceso a trabajo formal en las últimas. Ambos grupos presentaron dificultad en la obtención de turnos, percibiendo trato más amable las primeras y mayor comprensión de indicaciones las segundas. En la asistencia médica se halló menor posibilidad de cumplir con indicaciones en familias migrantes. Conclusión: Los resultados reflejan similares características de atención pediátrica ambulatoria para familias nativas y migrantes extranjeras (AU)
Introduction: Migration has increased worldwide due to multiple causes. In our country, foreigners account for 4.5% of the population of whom 69% come from neighboring countries. The Law of Migration N°25.871 guarantees equal rights for immigrants and Argentinians. In Commune 8 (City of Buenos Aires) 19.9% of the population is foreign born. Their primary care attention is covered by, among others, Health Care and Community Action Centers N° 5 and 18. Hospital Juan P. Garrahan is a regional referral center. The aim of this study was to describe the characteristics of the response of the Health Care System, specifically, comparing access to and satisfaction with first-level care and disease prevention among immigrant and native Argentinian families. Methods: A multicenter, observational, cross-sectional study was conducted through semi-structured interviews with immigrant and native Argentinian families between July 2014 and June 2015. Results were expressed in rates and percentages overall and comparing both groups. Results: 287 families were interviewed, 52% were native and 48% immigrants. Reduced access to formal employment was found in the latter group. Both groups reported difficulties in obtaining appointments, perceiving a more friendly treatment in the former and better understanding of the indications in the latter group. Regarding medical care, less possibilities to adhere to the indications were found in immigrant families. Conclusion: Our results show similar pediatric outpatient health-care characteristics for native and immigrant families (AU)

OBJECTIVES: Premarin and ketoconazole are affordable secondary hormonal options available for castrate-resistant prostate cancer (CRPC) in Jamaica. The aim of this study was to compare the relative efficacy of both drugs to decrease prostate-specific antigen (PSA) in CRPC in a population of patients of predominantly African escent. SUBJECTS AND METHODS: This study retrospectively identified patients with CRPC that presented to the University Hospital of the West Indies (January 1, 2009-December 31, 2013) and patients from a private urology clinic (November 2, 2005-June 3, 2015). The primary endpoint was to identify the proportion of patients with a decline of ¡Ý 50% in PSA level after treatment. The relative efficacy was assessed by the time to progression (TTP), an increase in PSA of 25% above nadir with PSA progression defined by Prostate Cancer Clinical Trials Working Group2 criteria. RESULTS: Thirty-five patients diagnosed with CRPC were identified; 32 initially treated with premarin and three with ketoconazole. Nine of the patients initially on premarin were crossed over to the ketoconazole treatment roup, bringing to twelve the patients treated with ketoconazole. Decline in PSA of ¡Ý 50% was observed in 43.8% (14 of32) and 25% (3 of 12) of patients on premarin and ketoconazole, respectively. The median (95% CI) TTP for patients treated with premarin was 24.00 (19.28, 28.724)months and ketoconazole was 13.54 (1.66, 25.41) months with no statistically significant difference between the groups (p = 0.107; log rank test). CONCLUSION: The study did not identify differences in the relative efficacy between premarin and ketoconazole in treating patients with CRPC.

Patients with pulmonary hypertension are some of the most challenging for an anaesthesiologist to manage. Pulmonary hypertension in patients undergoing surgical procedures is associated with high morbidity and mortality due to right ventricular failure, arrhythmias and ischaemia leading to haemodynamic instability. Lung transplantation is the only therapeutic option for end-stage lung disease. Patients undergoing lung transplantation present a variety of challenges for anaesthesia team, but pulmonary hypertension remains the most important. The purpose of this article is to review the anaesthetic management of pulmonary hypertension during lung transplantation, with particular emphasis on the choice of anaesthesia, pulmonary vasodilator therapy, inotropic and vasopressor therapy, and the most recent intraoperative monitoring recommendations to optimize patient care (AU)
La presencia de hipertensión pulmonar en el paciente quirúrgico constituye un reto para el anestesiólogo, dado que se asocia con una elevada morbilidad y mortalidad debido a lo frecuente del fallo del ventrículo derecho y colapso circulatorio. El trasplante pulmonar es la última opción terapéutica en los pacientes con insuficiencia respiratoria terminal. Estos pacientes representan un reto para el anestesiólogo siendo la hipertensión pulmonar el más importante. El propósito de esta artículo es la revisión del manejo anestésico de la hipertensión pulmonar durante el trasplante de pulmón, con especial énfasis en la elección del tipo de anestesia, uso de vasodilatadores pulmonares, soporte inotrópico y vasopresor, y monitorización intraoperatoria (AU)

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.

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.

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.

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 (ϲ = 24.26for 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 (ϲ =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 (ϲ = 8.41, p < 0.01). When compared with SDM, respondents receiving PIL were more likely to indicate that PIL was easy to read (ϲ = 20.00, p < 0.001), attractive (ϲ = 12.45, p < 0.001) and they were more likely to recommend distribution of their reading material to other patients (ϲ = 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.
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 (ϲ = 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 (ϲ =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 (ϲ = 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 (ϲ = 20.00, p < 0.001) y atractivo (ϲ = 12.45, p < 0.001), y por otra, una mayor tendencia a recomendar la distribución de su material de lectura a otros pacientes (ϲ = 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.

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.
