Desempeño de las RISS en relación al acceso, coordinación y calidad de la atención en cáncer de mama y diabetes mellitus tipo 2 en Colombia

El objetivo de este capítulo es mostrar los resultados de investigación del desempeño de las redes de servicios de salud frente a diferentes dimensiones relacionadas al acceso, coordinación y calidad de la atención en dos enfermedades crónicas como es el cáncer de mama y la diabetes en Colombia, importantes patologías por su incidencia e impacto así como por la necesidad de la mecanismos efectivos de coordinación para la adecuada atención de los usuarios del sistema de salud. Por tanto, se realiza el análisis del desempeño de dos redes de servicios de salud en la atención de usuarias con diagnostico confirmado de cáncer de mama, vinculadas unas a redes pertenecientes al régimen contributivo y otras al régimen subsidiado. Redes que también fueron consideradas para el análisis del desempeño en la atención de usuarios con diagnostico confirmado de diabetes, en el que de manera adicional participó otra red perteneciente al régimen subsidiado con área de operación en el municipio de Soacha, puesto que las dos anteriores tiene influencia en la ciudad de Bogotá. La fuente primaria de los datos fue la historia clínica y éstos fueron extraídos de acuerdo a ciertos indicadores seleccionados por el equipo investigador a través de un previo proceso de validación y a partir de su importancia para evidenciar el desempeño de las redes de servicios de salud en las dimensiones enunciadas anteriormente. Se muestran los resultados del estudio, a partir de los cuales se propone una breve discusión y conclusiones.

Carcinoma de tiroides una verdadera pandemia?

El diagnóstico de cáncer de tiroides se ha incrementado y las posibilidades de detección de una enfermedad subclínica son altas, toda vez que disponemos de herramientas de detección más sensibles y de fácil acceso. Por ende, el clínico requiere conocer la historia natural del nódulo tiroideo y del carcinoma papilar de tiroides de bajo riesgo para brindar a su paciente el mejor tratamiento basado en la evidencia clínica. El objetivo de esta revision es reconocer los elementos clínicos que han condicionado el aumento inusitado de casos de cáncer de tiroides. Conclusión: El sobrediagnóstico del cáncer de tiroides es una realidad, que se posibilita por el uso extendido de biopsia por aspiración con aguja fina ((BACAF)) después de la detección de un nódulo tiroideo, en gran parte de manera incidental, sin acarrear la mayoría de las veces un mejor pronóstico después de su tratamiento.

Las prácticas de recursos humanos y su incidencia en el bienestar laboral de los empleados

El objetivo del presente trabajo es formular, mediante una profunda revisión documental, bibliográfica y empírica, una fundamentación teórica sobre si existe o no incidencia de las prácticas de recursos humanos sobre el bienestar laboral de los empleados, y el que grado en que esta se presenta sobre aspecto como el engagement y la satisfacción laboral. Se realizó la revisión de múltiples estudios empíricos que aportaran evidencia sobre la relación que se presenta entre las principales prácticas de recursos humanos – provisión de personal, formación y desarrollo, promoción de personal, evaluación de desempeño, compensación y pago, y balance trabajo-familia – y el bienestar laboral, representado en el engagement y satisfacción en el trabajo de los empleados. Los resultados de este trabajo indican la existencia de una relación e incidencia de las prácticas de recursos humanos, el bienestar laboral, el engagement y la satisfacción laboral. De igual forma se encontró que estas relaciones son principalmente de carácter positivo, lo cual indica que las organizaciones que desarrollan este tipo de prácticas en su interior, fomentan tanto el desarrollo y la presencia de bienestar laboral en sus empleados, como su perdurabilidad.

Riesgo de accidentes biológicos en estudiantes de la salud: revisión de la literatura en los últimos 14 años.

Introducción: Todos los trabajadores del área de la salud están en riesgo de padecer un accidente biológico. No obstante los estudiantes de estas aéreas, pueden presentar más riesgo porque apenas están en formación y no tienen la práctica o experiencia suficiente. Existen varios artículos que han estudiado la incidencia y prevalencia de accidentes biológicos en los trabajadores del área de la salud, Sin embargo, sobre esta problemática de la población estudiantil del área de la salud, se encuentra menos literatura. Por lo tanto con esta revisión sistemática se busca analizar y actualizar este tema. Métodos: Se realizó una revisión de la literatura científica de artículos publicados en los últimos 14 años, en relación con la prevalencia de accidentes biológicos en estudiantes de medicina, odontología, enfermería y residentes del área de la salud a nivel mundial. Se llevó a cabo la búsqueda en la base de datos de Pubmed, encontrando un total de 100 artículos, escritos en inglés, francés, español o portugués. Resultados: Las prevalencias encontradas sobre accidentes biológicos en estudiantes fueron las siguientes: en países europeos a nivel de enfermería los valores oscilan entre 10.2 % a 32%, en medicina fueron del 16%-58.8%, y en odontología del 21 %. En países asiáticos, se encontró que en enfermería el porcentaje varía de 49%-96 %, en medicina van del 35% -68%, y en odontología varia de 68.a 75.4%. En Norte América, en medicina las cifras fluctúan alrededor del 11-72.7 % y en odontología giran alrededor del 19.1%. Finalmente respecto a Suramérica la prevalencia fue de 31.2 a 46.7% en medicina, y del 40% en enfermería. Conclusiones: Por lo anterior se pudo concluir que, la prevalencia de accidentes biológicos en los estudiantes del área de la salud es elevada y varía según el continente en el que se encuentren.

Efectividad del tratamiento inmunomodulador con leucocitos alogénicos, en aborto involuntario recurrente. Revisión sistemática y metaanálisis

Dentro del marco del aborto involuntario recurrente (AIR), se han propuesto causas autoinmunes y alogénicas, e implementación de terapias como la inmunización activa con leucocitos alogénicos de la pareja o de donantes. La evidencia disponible en cuanto a la efectividad de estos tratamientos es contradictoria, por lo que se desea realizar una revisión sistemática para evaluar la efectividad de la inmunización activa con leucocitos alogénicos de la pareja o de donantes para esta condición. Se realizó un estudio tipo revisión sistemática de la literatura, usando las siguientes bases de datos: Medline, Embase, Cochrane Library y Scielo. Se realizó una búsqueda a través del registro de ensayos clínicos del Instituto Nacional de Salud de los Estados Unidos (www.clinicaltrials.gov) y, una búsqueda manual a través de las referencias de los estudios seleccionados siguiendo la estrategia de bola de nieve. Se seleccionaron ensayos clínicos y estudios de cohorte analítica, en idioma inglés y español. Se realizó un análisis cuantitativo de la información por medio de un metaanálisis. El tratamiento inmunomodulador con linfocitos puede considerarse como una terapia efectiva para mantener la gestación y lograr recién nacido vivo según resultados estadísticos; sin embargo la calidad de los estudios incluidos es baja, por lo que no se aconseja para la práctica rutinaria. Se sugiere la realización de estudios con metodologías robustas y que apoyen los resultados presentados en esta investigación.

Caracterização das infecções do trato urinário de origem microbiana - casuística de um hospital veterinário em Lisboa

As infecções do trato urinário (ITU’s) são doenças infecciosas frequentes na prática clínica veterinária, sendo fundamental uma correta antibioterapia, principalmente pelo crescente desenvolvimento de resistências bacterianas aos antibióticos. Realizou-se um estudo retrospectivo, englobando 86 animais admitidos no Hospital Veterinário do Restelo, submetidos a urocultura, com o objetivo de caracterizar as ITU’s microbianas neste hospital, avaliando a sua epidemiologia e susceptibilidade antibiótica das bactérias isoladas. Da totalidade das uroculturas realizadas (n=86), 28 foram positivas, 18 em canídeos e 10 em felídeos, sem predisposição racial, mais em fêmeas nos canídeos e em machos nos felídeos. A idade média dos animais com ITU foi 8 anos nos canídeos e 10 anos nos felídeos. Todas as ITU´s foram monobacterianas, sendo o microorganismo mais frequentemente isolado a Escherichia coli. Verificou-se multirresistência em 10 das 28 bactérias isoladas. A gentamicina foi o antibiótico com melhor perfil de sensibilidade global e o que apresentou mais resistências foi a tetraciclina. O antibiótico mais prescrito de forma empírica foi a enrofloxacina. Este estudo, especialmente se realizado de forma periódica, poderá ser um contributo para a elaboração de guias institucionais de antibioterapia adequada e minimização do aparecimento de resistências bacterianas.

Caracterização das infeções do trato urinário de origem microbiana : casuística de um Hospital Veterinário de Lisboa

As infeções do trato urinário (ITU’s) são doenças infeciosas frequentes na prática clínica veterinária, sendo fundamental uma correta antibioterapia, principalmente pelo crescente desenvolvimento de resistências bacterianas aos antibióticos. Realizou-se um estudo retrospetivo, englobando 86 animais admitidos no Hospital Veterinário do Restelo, submetidos a urocultura, com o objetivo de caracterizar as ITU’s microbianas neste hospital, avaliando a sua epidemiologia e suscetibilidade antibiótica das bactérias isoladas.

Treatment of written verb and written sentence production in an individual with aphasia: A clinical study

Background: Although the efficacy of treatments for spoken verb and sentence production deficits in aphasia has been documented widely, less is known about interventions for written verb and written sentence production deficits. Aims: This study documents a treatment aiming to improve production of (a) written subject-verb sentences (involving intransitive verbs) and (b) written subject-verb-object sentences (involving transitive verbs). Methods & Procedures: The participant, a 63-year-old female aphasic speaker, had a marked language comprehension deficit, apraxia of speech, relatively good spelling abilities, and no hemiplegia. The treatment involved intransitive verbs producing subject-verb active sentences and transitive verbs producing subject-verb-object active non-reversible sentences. The treatment was undertaken in the context of current UK clinical practice. Outcomes & Results: Statistical improvements were noted for the trained sets of verbs and sentences. Other improvements were also noted in LW's ability to retrieve some non-treated verbs and construct written sentences. Treatment did not generalise to sentence comprehension and letter spelling to dictation. Conclusions: Our participant's ability to write verbs and sentences improved as a result of the treatment.

Randomized controlled trial of full and brief cognitive-behaviour therapy and wait-list for paediatric obsessive-compulsive disorder

Background: Reviews and practice guidelines for paediatric obsessive-compulsive disorder (OCD) recommend cognitive-behaviour therapy (CBT) as the psychological treatment of choice, but note that it has not been sufficiently evaluated for children and adolescents and that more randomized controlled trials are needed. The aim of this trial was to evaluate effectiveness and optimal delivery of CBT, emphasizing cognitive interventions. Methods: A total of 96 children and adolescents with OCD were randomly allocated to the three conditions each of approximately 12 weeks duration: full CBT (average therapist contact: 12 sessions) and brief CBT (average contact: 5 sessions, with use of therapist-guided workbooks), and wait-list/delayed treatment. The primary outcome measure was the child version of the semi-structured interviewer-based Yale-Brown Obsessive Compulsive Scale. Clinical Trial registration: http://www.controlled-trials.com/ISRCTN/; unique identifier: ISRCTN29092580. Results: There was statistically significant symptomatic improvement in both treatment groups compared with the wait-list group, with no significant differences in outcomes between the two treatment groups. Controlled treatment effect sizes in intention-to-treat analyses were 2.2 for full CBT and 1.6 for brief CBT. Improvements were maintained at follow-up an average of 14 weeks later. Conclusions: The findings demonstrate the benefits of CBT emphasizing cognitive interventions for children and adolescents with OCD and suggest that relatively lower therapist intensity delivery with use of therapist-guided workbooks is an efficient mode of delivery.

Randomized controlled trial of parent-enhanced CBT compared with individual CBT for obsessive-compulsive disorder in young people

Objective: Obsessive-compulsive disorder (OCD) in young people can be effectively treated with Cognitive Behavior Therapy (CBT). Practice guidelines in the United Kingdom recommend that CBT be delivered with parental or family involvement; however, there is no evidence from randomized trials that this enhances effectiveness. The aim of this trial was to assess if CBT with high parental involvement was more effective than CBT with low parental involvement (individual CBT) in reducing symptoms of OCD. Method: Fifty young people ages 12–17 years with OCD were randomly allocated to individual CBT or parent-enhanced CBT. In parent-enhanced CBT parents attended all treatment sessions; in individual CBT, parents attended only Sessions 1, 7, and the final session. Participants received up to 14 sessions of CBT. Data were analyzed using intent-to-treat and per-protocol methods. The primary outcome measure was the Children’s Yale-Brown Obsessive Compulsion Scale (Scahill et al., 1997). Results: Both forms of CBT significantly reduced symptoms of OCD and anxiety. Change in OCD symptoms was maintained at 6 months. Per-protocol analysis suggested that parent-enhanced CBT may be associated with significantly larger reductions in anxiety symptoms. Conclusions: High and low parental involvement in CBT for OCD in young people were both effective, and there was no evidence that 1 method of delivery was superior on the primary outcome measure. However, this study was small. Future trials should be adequately powered and examine interactions with the age of the young person and comorbid anxiety disorders.

High density lipoprotein: guardian of the vascular system?

The role of low-density lipoprotein in the development of coronary heart disease (CHD) is well recognised. There is also growing evidence that high-density lipoprotein cholesterol (HDL-C) is a powerful inverse predictor for premature CHD and that maintaining a high HDL-C level may guard against atherosclerosis. Patients with low HDL-C levels often also have central obesity, insulin resistance and other features of the metabolic syndrome. This syndrome is both increasingly common and strongly implicated in the growing worldwide epidemic of type 2 diabetes. HDL-C may be increased by lifestyle changes, e.g. weight loss, physical activity and smoking cessation. Pharmacological agents such as fibrates, niacin and statins have also been shown significantly to elevate HDL-C. Although current guidelines are beginning to recognise the protective role of HDL-C level in preventing coronary events, HDL-C should be adopted soon as a target for intervention in its own right.

Obsessive Compulsive Treatment Efficacy Trial (OCTET) comparing the clinical and cost effectiveness of self-managed therapies: study protocol for a randomised controlled trial

Background: UK National Institute of Health and Clinical Excellence guidelines for obsessive compulsive disorder (OCD) specify recommendations for the treatment and management of OCD using a stepped care approach. Steps three to six of this model recommend treatment options for people with OCD that range from low-intensity guided self-help (GSH) to more intensive psychological and pharmacological interventions. Cognitive behavioural therapy (CBT), including exposure and response prevention, is the recommended psychological treatment. However, whilst there is some preliminary evidence that self-managed therapy packages for OCD can be effective, a more robust evidence base of their clinical and cost effectiveness and acceptability is required. Methods/Design: Our proposed study will test two different self-help treatments for OCD: 1) computerised CBT (cCBT) using OCFighter, an internet-delivered OCD treatment package; and 2) GSH using a book. Both treatments will be accompanied by email or telephone support from a mental health professional. We will evaluate the effectiveness, cost and patient and health professional acceptability of the treatments. Discussion: This study will provide more robust evidence of efficacy, cost effectiveness and acceptability of self-help treatments for OCD. If cCBT and/or GSH prove effective, it will provide additional, more accessible treatment options for people with OCD.

Clinical implications of cognitive bias modification for interpretative biases in social anxiety: an integrative literature review

Cognitive theories of social anxiety indicate that negative cognitive biases play a key role in causing and maintaining social anxiety. On the basis of these cognitive theories, laboratory-based research has shown that individuals with social anxiety exhibit negative interpretation biases of ambiguous social situations. Cognitive Bias Modification for interpretative biases (CBM-I) has emerged from this basic science research to modify negative interpretative biases in social anxiety and reduce emotional vulnerability and social anxiety symptoms. However, it is not yet clear if modifying interpretation biases via CBM will have any enduring effect on social anxiety symptoms or improve social functioning. The aim of this paper is to review the relevant literature on interpretation biases in social anxiety and discuss important implications of CBM-I method for clinical practice and research.

Discrepancies between clinical diagnoses and autopsy findings

Autopsy examination is considered to be an essential element for medical auditing and teaching. Despite the significant progress in diagnostic procedures, autopsy has not always confirmed the clinical diagnosis. In the present study, we compared the diagnosis recorded on medical charts with reports of 96 autopsies performed at the University Teaching Hospital of the Faculdade de Medicina de Botucatu, Botucatu, SP, Brazil, between 1975 and 1982, and of 156 autopsies performed at the same institution between 1992 and 1996. The clinical diagnosis of the basic cause of death was confirmed at autopsy in 77% of cases. The percent confirmation fell to 60% when the immediate terminal cause of death was considered, and in 25% of cases, the terminal cause was only diagnosed at autopsy. The discrepancies between clinical and autopsy diagnosis were even larger for secondary diagnoses: 50% of them were not suspected upon clinical diagnosis. Among them, we emphasize the diagnosis of venous thromboses (83%), pulmonary embolisms (80%), bronchopneumonias (46%) and neoplasias (38%). Iatrogenic injuries were very frequent, and approximately 90% of them were not described in clinical reports. Our results suggest that highly sensitive and specific diagnostic tests are necessary but cannot substitute the clinical practice for the elaboration of correct diagnoses.

Incidence of retromolar foramen in human mandibles: ethnic and clinical aspects

The retromolar foramen allows the passage of the neurovascular bundles that contribute to nutrition and innervation of the pulp and periodontium of the lower teeth. Knowledge of this anatomical variation may prevent complications in the anesthesia and surgical procedures in this area and serve as an anatomical landmark for ethnic identification. The aim of this study was to evaluate the impact of the retromolar foramen in human mandibles of adult Brazilians and discuss the clinical and ethnic related to the presence of this foramen. Were evaluated 222 human mandibles, dry, adults, Brazilians, independent of gender. The evaluation was performed by two examiners who standardized search from a previous anatomical study. The mandibles were analyzed: the presence of the retromolar foramen (bilateral or unilateral), the presence of the foramen on right and left sides, and the number of foramens present on each side. It was found that 59 had at least one mandible retromolar foramens resulting in an incidence of 26.58%. The retromolar foramen was present unilaterally in 41 mandibles and 18 bilaterally, with incidences of 18.47% and 12.16% respectively. on the right side, the retromolar foramen was present in incidences of 16.22% and 18.92% respectively The analysis of the right side of the mandibles revealed that 47.46%, 21.21% and 3.03% had one, two and three foramens, respectively The left side showed 55.93%, 16.22% and 8.11% of the 222 mandibles with one, two and three retromolar foramens, respectively The incidence of retromolar foramen in the Brazilian population is significant and should be considered in the planning and execution of procedures in several areas of clinical practice dentistry in order to avoid complications. Moreover, it was found that the incidence of retromolar foramen contributes to differentiation of ethnic groups in the area of forensic anthropology.
