Advanced Technological Support in Psychotherapy

Increasingly, mental health has become a global public health concern warranting evidenced-based studies to promulgate effective ways of ensuring good mental health among individuals. In recent times, technology has become an inherent part of psychotherapy delivery. This paper examines how information technology in the delivery of psychotherapy improves mental health outcomes and helps eradicate stigmatisation of patients with mental-illness. Relevant empirical studies and reviews from psychology, psychiatry, mental health, telemental health, and the psychotherapy literature were synthesized, and findings guided the discussions on policy and practice implications. Results revealed that the use of advanced technological support in psychotherapy delivery can avert challenges with individuals’ unwillingness to disclose sensitive issues about their lives, help overcome scarcity of mental facilities and skilled professionals, and improve help-seeking. Finally, the results revealed that the use of technological methods of psychotherapy may help reduce stigmatisation associated with utilising mental health facilities. Findings from this review have implications for psychotherapy delivery and anti-stigma campaigns (AU)

Occupational tuberculosis in South Africa: are health care workers adequately protected?

Setting: A provincial tertiary hospital in Gauteng province, South Africa, with a high burden of tuberculosis (TB) patients and high risk of TB exposure among health care workers (HCWs). Objective: To determine HCWs' adherence to recommended TB infection prevention and control practices, TB training and access to health services and HCW TB rates. Design: Interviews with 285 HCWs using a structured questionnaire as part of a large, international mixed-methods study. Results: Despite 10 HCWs (including seven support HCWs) acquiring clinical TB during their period of employment, 62.8% of interviewees were unaware of the hospital's TB management protocol. Receipt of training was low (34.5% of all HCWs and <5% of support HCWs trained on TB transmission; 27.5% of nurses trained on respirator use), as was use of respiratory protection (44.5% of HCWs trained on managing TB patients). Support HCWs were over 36 times more likely to use respiratory protection if trained; nurses who were trained were approximately 40 times more likely to use respirators if they were readily available. Conclusion: Improved coordination and uptake of TB infection prevention training is urgently needed, especially for non-clinical HCWs in settings of regular exposure to TB patients. Adequate supplies of appropriate respiratory protection must be made available.

Contexte : Un hôpital provincial de niveau tertiaire dans la province de Gauteng, Afrique du Sud avec de très nombreux patients avec tuberculose (TB) et un risque élevé d'exposition à la TB parmi les travailleurs de santé (HCW).Objectif : Déterminer l'observance des HCW vis-à-vis des pratiques recommandées de prévention de l'infection et de lutte contre la TB, la formation en matière de TB et l'accès aux services de santé, et le taux de TB chez les HCW.Schéma : Entretiens avec 285 HCW, basés sur un questionnaire structuré, dans le cadre d'une vaste étude internationale à multiples méthodes.Résultats : Bien que 10 HCW (dont sept personnels de soutien) aient eu une TB pendant leur période de travail, 62,8% des répondants n'étaient pas au courant du protocole de prise en charge de la TB dans l'hôpital. La couverture de la formation a été faible (34,5% de tous les HCW et moins de 5% des HCW de soutien sur la transmission de la TB ; 27,5% des infirmiers sur l'utilisation d'un masque respiratoire), tout comme l'utilisation d'une protection respiratoire (44,5% des HCW prenant en charge des patients TB). Les HCW de soutien ont été 36 fois plus susceptibles d'utiliser une protection respiratoire s'ils avaient été formés ; les infirmiers qui avaient été formés ont été environ 40 fois plus susceptibles d'utiliser des masques respiratoires s'ils étaient facilement disponibles.Conclusion : Une amélioration de la coordination et de la couverture de la formation à la prévention de l'infection TB est requise d'urgence, surtout pour les HCW de soutien dans les contextes d'exposition régulière aux patients TB. Des stocks suffisants de protection respiratoire doivent être disponibles.

Marco de referencia: Un hospital provincial de atención terciaria en la provincia de Gauteng de Suráfrica, donde se observa una alta carga de morbilidad por tuberculosis (TB) y un alto riesgo de exposición de los profesionales de salud (HCW) a la enfermedad.Objetivo: Evaluar la observancia de las prácticas de prevención y control de la infección tuberculosa, la capacitación en materia de TB y el acceso de los HCW a los servicios de atención y calcular la tasa de TB en este tipo personal.Método: Se entrevistaron 285 HCW mediante un cuestionario estructurado, en el marco de un extenso estudio internacional por métodos mixtos.Resultados: Pese a que 10 HCW (incluidos siete miembros del personal auxiliar) habían adquirido la enfermedad tuberculosa durante el período de su empleo, el 62,8% de los entrevistados no conocía el protocolo de manejo de la TB del hospital. La tasa de capacitación era baja (34,5% de todos los HCW y menos de 5% del personal auxiliar sobre la transmisión de la TB y 27,5% del HCW sobre la utilización de mascarillas respiratorias) y asimismo la utilización de la protección respiratoria (el 44,5% de los HCW que se ocupaban de pacientes con TB). La probabilidad de que personal auxiliar utilizara la protección respiratoria era 36 veces mayor al haber recibido capacitación; el personal de enfermería tenía una probabilidad 40 veces mayor de utilizar las mascarillas respiratorias cuando había sido formado y el material estaba al alcance.Conclusión: Se precisa con urgencia una mejor coordinación y una utilización más amplia de la formación sobre la prevención de la infección tuberculosa, sobre todo dirigida a los HCW auxiliares, en los entornos donde es corriente la exposición a pacientes tuberculosos. Es necesario contar con los suministros adecuados de protección respiratoria al alcance del personal.

Radiation doses and hazards from processing of crude oil at the Tema oil refinery in Ghana.

Processing of crude oil has been carried out in Ghana for more than four decades without measures to assess the hazards associated with the naturally occurring radionuclides in the raw and processed materials. This study investigates the exposure of the public to (226)Ra, (232)Th and (40)K in crude oil, petroleum products and wastes at the Tema oil refinery in Ghana using gamma-ray spectrometry. The study shows higher activity concentrations of the natural radionuclides in the wastes than the crude oil and the products with estimated hazard indices less than unity. The values obtained in the study are within recommended limits for public exposure indicating that radiation exposure from processing of the crude oil at the refinery does not pose any significant radiological hazard but may require monitoring to establish long-term effect on both public and workers.

Geometrical effects on thermal neutron reflection of hydrogenous moderators using 241Am-Be source.

The variation of thermal reflection parameter with thicknesses of water and paraffin moderators was measured using an instrument consisting of 1 Ci 241Am-Be isotopic neutron source and 3He neutron detector. Based on experimental data obtained from two different source-detector-sample geometries, analytical expressions were derived for calculation of reflection parameters for various moderator thicknesses. The measured data for the two geometries exhibit saturation curves with saturation achieved at about 8 and 16 cm when sample container was placed at top and side of the source holder, respectively. By locating the source holder along the vertical axis of the sample container, measurements showed that the reflection parameter was very sensitive with the axial location and was strongly dependent on the moderator and its thickness.
