Indirect child mortality estimation technique to identify trends of under-five mortality in Ethiopia.

Background: In sub-Saharan African countries, the chance of a child dying before the age of five years is high. The problem is similar in Ethiopia, but it shows a decrease over years. Methods: The 2000; 2005 and 2011 Ethiopian Demographic and Health Survey results were used for this work. The purpose of the study is to detect the pattern of under-five child mortality overtime. Indirect child mortality estimation technique is adapted to examine the under-five child mortality trend in Ethiopia. Results: From the result, it was possible to see the trend of under-five child mortality in Ethiopia. The under-five child mortality shows a decline in Ethiopia. Conclusion: From the study, it can be seen that there is a positive correlation between mother and child survival which is almost certain in any population. Therefore, this study shows the trend of under-five mortality in Ethiopia and decline over time.

"I’ll call you when we are ready" (One family’s experience of critical care and end of life decision making)

The purpose of this paper is to explore through narrative accounts one family's expérience of critical care, after the admission of a family member to an Intensive Care Unit (ICU) and their subséquent death five weeks later. Numerous studies support the need for effective communication and clear information to be given to the family. In this instance it was évident from their stories that there were numerous barriers to communication, including language and a lack of insight into the needs of the family. Many families do not understand the complexities of nursing care in an ICU so lack of communication by nursing staff was identified as uncaring behavior and encounters. Facilitating a family's proximity to a dying patient and encouraging them to participate in care helps to maintain some sensé of personal control. Despite a commitment to involving family members in care, which was enshrined in the Unit Philosophy, relatives were banished to the waiting room for hours. They experienced feelings of powerlessness and helplessness as they waited with other relatives for news following investigations or until 'the doctor had completed his rounds'. Explanations of "we must make 'the patient' comfortable" was no consolation for those who wished to be involved in care. The words "I'il call you when we are ready" became a mantra to the forgotten families who waited patiently for those with power to admit them to the ICU. Implications are this family felt they were left alone to cope with the traumatic expériences leading up to and surrounding the death. They felt mainly supported by the priest, who not only administered the last rites but provided spiritual support to the family and dealt sensitively with many issues. Paternalism in décision making when there is a moral obligation to ensure that discussions on end of life dilemmas are an inclusive process with families, doctors, nurses was not understood, therefore it caused conflict within the family over EOL décision making. The family felt that the opportunity to share expériences through telling and retelling their stories would enable them to reconfigure the past and create purpose in the future.

Suicide among young people and adults in Ireland: method characteristics, toxicological analysis and substance abuse histories compared

Objective: Information on factors associated with suicide among young individuals in Ireland is limited. The aim of this study was to identify socio-demographic characteristics and circumstances of death associated with age among individuals who died by suicide. Methods: The study examined 121 consecutive suicides (2007–2012) occurring in the southern eastern part of Ireland (Cork city and county). Data were obtained from coroners, family informants, and health care professionals. A comparison was made between 15-24-year-old and 25-34-year-old individuals. Socio-demographic characteristics of the deceased, methods of suicide, history of alcohol and drug abuse, and findings from toxicological analysis of blood and urine samples taken at post mortem were included. Pearson’s χ2 tests and binary logistic regression analysis were performed. Results: Alcohol and/or drugs were detected through toxicological analysis for the majority of the total sample (79.5%), which did not differentiate between 15-24-year-old and 25-34-year-old individuals (74.1% and 86.2% respectively). Compared to 25-34-year-old individuals, 15-24-year-old individuals were more likely to engage in suicide by hanging (88.5%). Younger individuals were less likely to die by intentional drug overdose and carbon monoxide poisoning compared to older individuals. Younger individuals who died between Saturday and Monday were more likely to have had alcohol before dying. Substance abuse histories were similar in the two age groups. Conclusion: Based on this research it is recommended that strategies to reduce substance abuse be applied among 25-34-year-old individuals at risk of suicide. The wide use of hanging in young people should be taken into consideration for future means restriction strategies.

End-of-life care in a cardiology department: have we improved?

nd-of-life care is not usually a priority in cardiology departments. We sought to evaluate the changes in end-of-life care after the introduction of a do-not-resuscitate (DNR) order protocol. Retrospective analysis of all deaths in a cardiology department in two periods, before and after the introduction of the protocol. Comparison of demographic characteristics, use of DNR orders, and end-of-life care issues between both periods, according to the presence in the second period of the new DNR sheet (Group A), a conventional DNR order (Group B) or the absence of any DNR order (Group C). The number of deaths was similar in both periods (n = 198 vs. n = 197). The rate of patients dying with a DNR order increased significantly (57.1% vs. 68.5%; P = 0.02). Only 4% of patients in both periods were aware of the decision taken about cardiopulmonary resuscitation. Patients in Group A received the DNR order one day earlier, and 24.5% received it within the first 24 h of admission (vs. 2.6% in the first period; P < 0.001). All patients in Group A with an implantable cardioverter defibrillator (ICD) had shock therapies deactivated (vs. 25.0% in the first period; P = 0.02). The introduction of a DNR order protocol may improve end-of-life care in cardiac patients by increasing the use and shortening the time of registration of DNR orders. It may also contribute to increase ICD deactivation in patients with these orders in place. However, the introduction of the sheet in late stages of the disease failed to improve patient participation.

Étude philosophique du renversement juridique canadien concernant l’aide médicale à mourir, à la lumière du débat Hart-Dworkin

Le 6 février 2015, la Cour suprême du Canada a rendu un jugement historique, unanime et anonyme. Dans l’arrêt Carter c. Canada (Procureur général), la Cour reconnaît que l’interdiction mur à mur de l’aide médicale à mourir porte atteinte aux droits constitutionnels de certaines personnes. En effet, les adultes capables devraient pouvoir demander l’aide d’un médecin pour mettre fin à leur vie s’ils respectent deux critères : consentir clairement et de façon éclairée à quitter ce monde et être affecté de problèmes de santé graves et irrémédiables leur causant des souffrances persistantes et intolérables. Or, cette décision constitue un renversement juridique, car un jugement inverse avait été rendu en 1993. En effet, vingt-deux ans auparavant, la Cour suprême avait jugé à cinq contre quatre que l’interdiction du suicide assisté était constitutionnelle. Dans l’arrêt Rodriguez c. Colombie-Britannique, la majorité avait statué que la protection du caractère sacré de la vie dans toute circonstance, tant pour les personnes vulnérables que pour les adultes capables, était une raison suffisante pour ne pas accorder de dérogation aux articles du Code criminel qui concernent le suicide assisté. Les juges majoritaires craignent alors que toute ouverture à l’aide au suicide entraine un élargissement progressif des critères d’admissibilité, ce que plusieurs appellent l’argument du « doigt dans l’engrenage ». Dans le cadre de ce mémoire, le renversement juridique Rodriguez-Carter sera analysé à la lumière du débat entre H. L. A. Hart et Ronald Dworkin. Alors que le premier défend une nouvelle version du positivisme modéré, le second offre une théorie nouvelle et innovatrice, nommée l’interprétativisme. L’objectif est simple : déterminer laquelle de ces deux théories explique le mieux le renversement juridique canadien concernant l’aide médicale à mourir. L’hypothèse initiale soutient que les deux théories pourront expliquer ledit renversement, mais que l’une le fera mieux que l’autre.

The impact and control of malignant catarrhal fever in Tanzania

Malignant Catarrhal Fever (MCF), an often-lethal infectious disease, presents as a variable complex of lesions in susceptible ungulate species. The disease is caused by a -herpesvirus following transmission from an inapparent carrier host. Two major epidemiological forms exist: wildebeest-associated MCF (WA-MCF), in which the virus is transmitted to susceptible species by wildebeest calves less than approximately four months of age, and sheepassociated MCF (SA-MCF) in which the virus is spread by sheep (primarily adolescents). Due to the lack of an in-vitro propagation system for the causative agent of the more economically significant SA-MCF, and with the expectation that cross-protective immunity may be provided, vaccine development has focused on the more easily propagated alcelaphine herpesvirus-1 (AlHV-1) that causes WA-MCF. In 2008 a direct viral challenge trial showed that a novel vaccine, employing an attenuated AlHV-1 (atAlHV-1) `C5000 virus strain, protected British Friesian-Holstein (FH) cattle against an intranasal challenge with virulent AlHV-1 `C5000 virus. For cattle keeping people living near wildebeest calving areas in sub-Saharan Africa an effective vaccine would have value as it would release them from the costly annual disease avoidance strategy of having to move their herds away from the oncoming wildebeest. On the other hand, an effective vaccine will release herd owners from the need to avoid MCF, allowing them to graze their cattle alongside wildebeest on the highly nutritious pastures of the calving areas. As such conservationists have raised concerns that the development of a vaccine might lead to detrimental grazing competition. The principle objective of this study was to test the novel vaccine on Tanzanian shorthorn zebu cross cattle (SZC).We did this firstly using a natural challenge field trial (Chapter Two) which demonstrated that immunisation with the atAlHV-1 vaccine was well tolerated and induced an oro-nasopharyngeal AlHV-1-specific and -neutralising antibody response. This resulted in an immunity in SZC cattle that was partially protective and reduced naturally transmitted infection by 56%. We also demonstrated that non-fatal infections occurred with a much higher frequency than previously thought. Because the calculated efficacy of the vaccine was less than that seen in British FH cattle we wanted to determine whether host factors, particular to SZC cattle, had impacted the outcomes of the field trial. To do this we repeated the 2008 direct viral challenge trial using SZC cattle (Chapter Four). During this trial we also investigated whether the recombinant bacterial flagellin monomer (FliC), when used as an adjuvant, might improve the vaccine’s efficacy. The findings from this trial indicated that direct challenge with pathogenic AlHV-1 is effective at inducing MCF in SZC cattle and that FliC is not an appropriate adjuvant for this vaccine. Furthermore, with less control group cattle dying of MCF than expected we speculate that SZC cattle may have a degree of resistance to MCF that affords them protection from infection and developing fatal disease. In Chapter Three we investigated aspects of the epidemiology of MCF, specifically whether wildebeest placenta, long implicated by Maasai cattle owners as a source of MCF, might play a role in viral transmission. Additionally, through comparative sequence analysis, at two specific genes (A9.5 and ORF50) of wild-type and atAlHV-1, we investigated whether the `C5000 strain, the source of which was taken from Africa more than 40 years ago, was appropriate for vaccine development. The detection of AlHV-1 virus in approximately 50% of placentae indicated that infection can occur in-utero and that this tissue might play a role in disease transmission. And, despite describing three new alleles of the A9.5 gene (supporting previous evidence that this gene is polymorphic and encodes a secretory protein with interleukin-4 as the major homologue), the observation that the most frequently detected haplotypes, in both wild-type and attenuated AlHV-1, were identical suggests that AlHV-1 has a slow molecular clock and that the attenuated strain was appropriate for vaccine development. In Chapter Five we present the first quantitative assessment of the annual MCF avoidance costs that Maasai pastoralists incur. In particular we estimated that as a result of MCF avoidance 64% of the total daily milk yield during the MCF season was not available to be used by the 81% of the family unit remaining at the permanent boma. This represents an upper-bound loss of approximately 8% of a household0s annual income. Despite these considerable losses we concluded that, given an incidence of fatal MCF in cattle living in wildebeest calving areas of 5% to 10%, if herd owners were to stop trying to avoid MCF by allowing their cattle to graze alongside wildebeest, any gains made through increased availability of milk, improved body condition and reduced energy demands would be offset by an increase in MCF-incidence. With the development of an effective vaccine, however, this alternative strategy might become optimal. The overall conclusion we draw therefore is that, despite the substantial costs incurred each year avoiding MCF, the partial protection afforded by the novel vaccine strategy is not sufficient to warrant a wholesale change in disease avoidance strategy. Nonetheless, even the partial protection provided by this vaccine could be of value to protect animals that cannot be moved, for example where some of the herd remain at the boma to provide milk or where land-use changes make traditional disease avoidance difficult. Furthermore, the vaccine may offer a feasible solution to some of the current land-use challenges and conflicts, providing a degree of protection to valuable livestock where avoidance strategies are not possible, but with less risk of precipitating the potentially damaging environmental consequences, such as overgrazing of highly nutritious seasonal pastures, that might result if herd owners decide they no longer need to avoid wildebeest.

Evaluación del desempeño de pruebas diagnósticas de tuberculosis en pacientes VIH positivo en dos hospitales públicos de Bogotá

La tuberculosis TB es una de las principales causas de muerte en el mundo en individuos con infección por VIH. En Colombia esta coinfección soporta una carga importante en la población general convirtiéndose en un problema de salud pública. En estos pacientes las pruebas diagnósticas tienen sensibilidad inferior y la enfermedad evoluciona con mayor frecuencia hacia formas diseminadas y rápidamente progresivas y su diagnóstico oportuno representa un reto en Salud. El objetivo de este proyecto es evaluar el desempeño de las pruebas diagnósticas convencionales y moleculares, para la detección de TB latente y activa pacientes con VIH, en dos hospitales públicos de Bogotá. Para TB latente se evaluó la concordancia entre las pruebas QuantiFERON-TB (QTF) y Tuberculina (PPD), sugiriendo superioridad del QTF sobre la PPD. Se evaluaron tres pruebas diagnósticas por su sensibilidad y especificidad, baciloscopia (BK), GenoType®MTBDR plus (Genotype) y PCR IS6110 teniendo como estándar de oro el cultivo. Los resultados de sensibilidad (S) y especificidad (E) de cada prueba con una prevalencia del 19,4 % de TB pulmonar y extrapulmonar en los pacientes que participaron del estudio fue: BK S: 64% E: 99,1%; Genotype S: 77,8% E: 94,5%; PCRIS6110 S: 73% E: 95,5%, de la misma forma se determinaron los valores predictivos positivos y negativos (VPP y VPN) BK: 88,9% y 94,8%, Genotype S: 77,8% E: 94,5%; PCRIS6110 S: 90% y 95,7%. Se concluyó bajo análisis de curva ROC que las pruebas muestran un rendimiento diagnóstico similar por separado en el diagnóstico de TB en pacientes con VIH, aumentando su rendimiento diagnostico cuando se combinan

Ideación suicida y desesperanza en pacientes con cáncer

El objetivo de la presente investigación fue identificar la relación entre ideación suicida y desesperanza en 160 pacientes con cáncer. La ideación suicida se midió a través de dos ítems de una entrevista semiestructurada, la escala de ideación suicida (ISS), el ítem 9 del inventario de depresión de Beck (BDI-IA). La desesperanza se midió con la escala de desesperanza de Beck (BHS). Los resultados obtenidos indicaron una relación significativa (p=.000) entre ideación suicida y desesperanza; una prevalencia de ideación suicida en los pacientes con cáncer entre 4.4% y 13.8% y de riesgo de suicidio entre 5.6% y 30.6%; y algún grado de desesperanza en 31.9 % de los participantes. De acuerdo con lo anterior, se confirma que existe relación entre la desesperanza y la ideación suicida en pacientes oncológicos adultos. Adicionalmente, que estas variables están presentes en los pacientes y que ameritan atención en la intervención interdisciplinaria.

¿Cambiar para seguir igual? la experiencia de la oposición política rusa: del legado de la Perestroika a la democracia soberana

El colapso de la Unión Soviética a inicios de los años noventa del siglo pasado, constituyó para Rusia un punto de partida para su reconfiguración y reestructuración como un país independiente. En este proceso de reconfiguración y reestructuración Rusia ha adoptado diferentes elementos de la cultura política occidental; situación que resulta de gran interés, toda vez que en los años de la Guerra Fría la Rusia comunista encarnaba la antítesis de Occidente a nivel ideológico, político y económico. Esta investigación pretende estudiar la oposición política en Rusia entre los años 2004 y 2012, y, con ello, presentar algunos elementos clave en la comprensión de las acciones, relaciones e influencia de los diferentes actores del nuevo sistema político de esta potencia mundial.

Clínica e cirurgia de pequenos animais

Este relatório foi elaborado na sequencia do estágio curricular realizado pelo autor, ente 28 de setembro de 2015 e 28 de março de 2016, no Hospital Clínico Veterinario de la Universidad CEU Cardenal Herrera (HCV CEU-UCH), em Alfara del Patriarca, Valência, Espanha. A infeciologia foi a área da clínica médica mais representativa (28%), sendo o vírus da imunodeficiência felina (FIV) o agente infecioso registado mais frequentemente (19%). É importante reconhecer e diagnosticar esta infeção de forma a aplicar um maneio adequado aos pacientes infetados, melhorando a sua qualidade de vida e prevenindo a propagação do vírus. A infeção provocada pelo FIV raramente provoca uma síndrome severa, porém, várias alterações podem decorrer. Apesar do FIV provocar uma infeção crónica, com os cuidados adequados, os pacientes infetados poderão viver vidas longas, com uma boa qualidade de vida, e eventualmente acabar por morrer de causas não relacionadas com o FIV; Abstract: Small Animal Medicine and Surgery This report was elaborated following the externship performed by the author, between September 28th 2015 and March 28th 2016, at the Hospital Clínico Veterinario de la Universidad CEU Cardenal Herrera (HCV CEU-UCH), in Alfara del Patriarca, Valencia, Spain. The most frequent specialty field within the area of internal medicine was infectiology (28%), with feline immunodeficiency virus (FIV) being the infectious agent most frequently registered (19%). It is important to recognize and diagnose the infection caused by this agent accurately, so that the right measures of management can be applied, improving the life’s quality of the patient and reducing the risk of viral spreading. The infection by FIV rarely produces a severe syndrome, however many clinicopathologic disorders may occur. FIV causes a chronic infection, however, with the proper care, the infected cats may live long lives, with a fair quality, eventually ending up dying from causes unrelated to FIV.
