Abstract and Summary of Thesis: Background: Individuals with Major Mental Illness (such as schizophrenia and bipolar disorder) experience increased rates of physical health comorbidity compared to the general population. They also experience inequalities in access to certain aspects of healthcare. This ultimately leads to premature mortality. Studies detailing patterns of physical health comorbidity are limited by their definitions of comorbidity, single disease approach to comorbidity and by the study of heterogeneous groups. To date the investigation of possible sources of healthcare inequalities experienced by individuals with Major Mental Illness (MMI) is relatively limited. Moreover studies detailing the extent of premature mortality experienced by individuals with MMI vary both in terms of the measure of premature mortality reported and age of the cohort investigated, limiting their generalisability to the wider population. Therefore local and national data can be used to describe patterns of physical health comorbidity, investigate possible reasons for health inequalities and describe mortality rates. These findings will extend existing work in this area. Aims and Objectives: To review the relevant literature regarding: patterns of physical health comorbidity, evidence for inequalities in physical healthcare and evidence for premature mortality for individuals with MMI. To examine the rates of physical health comorbidity in a large primary care database and to assess for evidence for inequalities in access to healthcare using both routine primary care prescribing data and incentivised national Quality and Outcome Framework (QOF) data. Finally to examine the rates of premature mortality in a local context with a particular focus on cause of death across the lifespan and effect of International Classification of Disease Version 10 (ICD 10) diagnosis and socioeconomic status on rates and cause of death. Methods: A narrative review of the literature surrounding patterns of physical health comorbidity, the evidence for inequalities in physical healthcare and premature mortality in MMI was undertaken. Rates of physical health comorbidity and multimorbidity in schizophrenia and bipolar disorder were examined using a large primary care dataset (Scottish Programme for Improving Clinical Effectiveness in Primary Care (SPICE)). Possible inequalities in access to healthcare were investigated by comparing patterns of prescribing in individuals with MMI and comorbid physical health conditions with prescribing rates in individuals with physical health conditions without MMI using SPICE data. Potential inequalities in access to health promotion advice (in the form of smoking cessation) and prescribing of Nicotine Replacement Therapy (NRT) were also investigated using SPICE data. Possible inequalities in access to incentivised primary healthcare were investigated using National Quality and Outcome Framework (QOF) data. Finally a pre-existing case register (Glasgow Psychosis Clinical Information System (PsyCIS)) was linked to Scottish Mortality data (available from the Scottish Government Website) to investigate rates and primary cause of death in individuals with MMI. Rate and primary cause of death were compared to the local population and impact of age, socioeconomic status and ICD 10 diagnosis (schizophrenia vs. bipolar disorder) were investigated. Results: Analysis of the SPICE data found that sixteen out of the thirty two common physical comorbidities assessed, occurred significantly more frequently in individuals with schizophrenia. In individuals with bipolar disorder fourteen occurred more frequently. The most prevalent chronic physical health conditions in individuals with schizophrenia and bipolar disorder were: viral hepatitis (Odds Ratios (OR) 3.99 95% Confidence Interval (CI) 2.82-5.64 and OR 5.90 95% CI 3.16-11.03 respectively), constipation (OR 3.24 95% CI 3.01-3.49 and OR 2.84 95% CI 2.47-3.26 respectively) and Parkinson’s disease (OR 3.07 95% CI 2.43-3.89 and OR 2.52 95% CI 1.60-3.97 respectively). Both groups had significantly increased rates of multimorbidity compared to controls: in the schizophrenia group OR for two comorbidities was 1.37 95% CI 1.29-1.45 and in the bipolar disorder group OR was 1.34 95% CI 1.20-1.49. In the studies investigating inequalities in access to healthcare there was evidence of: under-recording of cardiovascular-related conditions for example in individuals with schizophrenia: OR for Atrial Fibrillation (AF) was 0.62 95% CI 0.52 - 0.73, for hypertension 0.71 95% CI 0.67 - 0.76, for Coronary Heart Disease (CHD) 0.76 95% CI 0.69 - 0.83 and for peripheral vascular disease (PVD) 0.83 95% CI 0.72 - 0.97. Similarly in individuals with bipolar disorder OR for AF was 0.56 95% CI 0.41-0.78, for hypertension 0.69 95% CI 0.62 - 0.77 and for CHD 0.77 95% CI 0.66 - 0.91. There was also evidence of less intensive prescribing for individuals with schizophrenia and bipolar disorder who had comorbid hypertension and CHD compared to individuals with hypertension and CHD who did not have schizophrenia or bipolar disorder. Rate of prescribing of statins for individuals with schizophrenia and CHD occurred significantly less frequently than in individuals with CHD without MMI (OR 0.67 95% CI 0.56-0.80). Rates of prescribing of 2 or more anti-hypertensives were lower in individuals with CHD and schizophrenia and CHD and bipolar disorder compared to individuals with CHD without MMI (OR 0.66 95% CI 0.56-0.78 and OR 0.55 95% CI 0.46-0.67, respectively). Smoking was more common in individuals with MMI compared to individuals without MMI (OR 2.53 95% CI 2.44-2.63) and was particularly increased in men (OR 2.83 95% CI 2.68-2.98). Rates of ex-smoking and non-smoking were lower in individuals with MMI (OR 0.79 95% CI 0.75-0.83 and OR 0.50 95% CI 0.48-0.52 respectively). However recorded rates of smoking cessation advice in smokers with MMI were significantly lower than the recorded rates of smoking cessation advice in smokers with diabetes (88.7% vs. 98.0%, p<0.001), smokers with CHD (88.9% vs. 98.7%, p<0.001) and smokers with hypertension (88.3% vs. 98.5%, p<0.001) without MMI. The odds ratio of NRT prescription was also significantly lower in smokers with MMI without diabetes compared to smokers with diabetes without MMI (OR 0.75 95% CI 0.69-0.81). Similar findings were found for smokers with MMI without CHD compared to smokers with CHD without MMI (OR 0.34 95% CI 0.31-0.38) and smokers with MMI without hypertension compared to smokers with hypertension without MMI (OR 0.71 95% CI 0.66-0.76). At a national level, payment and population achievement rates for the recording of body mass index (BMI) in MMI was significantly lower than the payment and population achievement rates for BMI recording in diabetes throughout the whole of the UK combined: payment rate 92.7% (Inter Quartile Range (IQR) 89.3-95.8 vs. 95.5% IQR 93.3-97.2, p<0.001 and population achievement rate 84.0% IQR 76.3-90.0 vs. 92.5% IQR 89.7-94.9, p<0.001 and for each country individually: for example in Scotland payment rate was 94.0% IQR 91.4-97.2 vs. 96.3% IQR 94.3-97.8, p<0.001. Exception rate was significantly higher for the recording of BMI in MMI than the exception rate for BMI recording in diabetes for the UK combined: 7.4% IQR 3.3-15.9 vs. 2.3% IQR 0.9-4.7, p<0.001 and for each country individually. For example in Scotland exception rate in MMI was 11.8% IQR 5.4-19.3 compared to 3.5% IQR 1.9-6.1 in diabetes. Similar findings were found for Blood Pressure (BP) recording: across the whole of the UK payment and population achievement rates for BP recording in MMI were also significantly reduced compared to payment and population achievement rates for the recording of BP in chronic kidney disease (CKD): payment rate: 94.1% IQR 90.9-97.1 vs.97.8% IQR 96.3-98.9 and p<0.001 and population achievement rate 87.0% IQR 81.3-91.7 vs. 97.1% IQR 95.5-98.4, p<0.001. Exception rates again were significantly higher for the recording of BP in MMI compared to CKD (6.4% IQR 3.0-13.1 vs. 0.3% IQR 0.0-1.0, p<0.001). There was also evidence of differences in rates of recording of BMI and BP in MMI across the UK. BMI and BP recording in MMI were significantly lower in Scotland compared to England (BMI:-1.5% 99% CI -2.7 to -0.3%, p<0.001 and BP: -1.8% 99% CI -2.7 to -0.9%, p<0.001). While rates of BMI and BP recording in diabetes and CKD were similar in Scotland compared to England (BMI: -0.5 99% CI -1.0 to 0.05, p=0.004 and BP: 0.02 99% CI -0.2 to 0.3, p=0.797). Data from the PsyCIS cohort showed an increase in Standardised Mortality Ratios (SMR) across the lifespan for individuals with MMI compared to the local Glasgow and wider Scottish populations (Glasgow SMR 1.8 95% CI 1.6-2.0 and Scotland SMR 2.7 95% CI 2.4-3.1). Increasing socioeconomic deprivation was associated with an increased overall rate of death in MMI (350.3 deaths/10,000 population/5 years in the least deprived quintile compared to 794.6 deaths/10,000 population/5 years in the most deprived quintile). No significant difference in rate of death for individuals with schizophrenia compared with bipolar disorder was reported (6.3% vs. 4.9%, p=0.086), but primary cause of death varied: with higher rates of suicide in individuals with bipolar disorder (22.4% vs. 11.7%, p=0.04). Discussion: Local and national datasets can be used for epidemiological study to inform local practice and complement existing national and international studies. While the strengths of this thesis include the large data sets used and therefore their likely representativeness to the wider population, some limitations largely associated with using secondary data sources are acknowledged. While this thesis has confirmed evidence of increased physical health comorbidity and multimorbidity in individuals with MMI, it is likely that these findings represent a significant under reporting and likely under recognition of physical health comorbidity in this population. This is likely due to a combination of patient, health professional and healthcare system factors and requires further investigation. Moreover, evidence of inequality in access to healthcare in terms of: physical health promotion (namely smoking cessation advice), recording of physical health indices (BMI and BP), prescribing of medications for the treatment of physical illness and prescribing of NRT has been found at a national level. While significant premature mortality in individuals with MMI within a Scottish setting has been confirmed, more work is required to further detail and investigate the impact of socioeconomic deprivation on cause and rate of death in this population. It is clear that further education and training is required for all healthcare staff to improve the recognition, diagnosis and treatment of physical health problems in this population with the aim of addressing the significant premature mortality that is seen. Conclusions: Future work lies in the challenge of designing strategies to reduce health inequalities and narrow the gap in premature mortality reported in individuals with MMI. Models of care that allow a much more integrated approach to diagnosing, monitoring and treating both the physical and mental health of individuals with MMI, particularly in areas of social and economic deprivation may be helpful. Strategies to engage this “hard to reach” population also need to be developed. While greater integration of psychiatric services with primary care and with specialist medical services is clearly vital the evidence on how best to achieve this is limited. While the National Health Service (NHS) is currently undergoing major reform, attention needs to be paid to designing better ways to improve the current disconnect between primary and secondary care. This should then help to improve physical, psychological and social outcomes for individuals with MMI.

Fundamento. Determinar si ajustar el tratamiento antidiabético al alta se relaciona con los resultados a 30 días en los pacientes con diabetes mellitus atendidos por hipoglucemia en un servicio de urgencias (SU). Método. Estudio observacional de cohorte retrospectivo. Se incluyeron todos los pacientes con diabetes mellitus con hipoglucemia dados del alta desde SU entre 2012-2014. La variable resultado fue un evento adverso por cualquier causa a los 30 días. Resultados. El estudio se realizó en 203 pacientes con edad media de 69,7 (DE 18,9) mayoritariamente con diabetes mellitus tipo 2. El diagnóstico de hipoglucemia fue principal en 162 (79%) y se realizó ajuste terapéutico en 98 (48%) casos. El no ajuste de tratamiento fue un factor independiente asociado con un evento adverso a los 30 días (OR=2,82; IC 95%=1,34-5,93; p=0,006). Conclusiones. No ajustar el tratamiento antidiabético al alta del SU podría ser un factor independiente de sufrir un resultado adverso a los 30 días en los pacientes con diabetes mellitus que presentaron hipoglucemia en un SU.

One of the known risk factors for abuse and neglect of the elderly is the decrease in functionat capacity, contributíng to self care dependency of instrumental actívities of daily living and basic activities of daily Itving (OMS, 2015). Methods: Cross-sectional study with non probabilistíc sample of 333 elderly, performed in a hospital, homes and day centers for the elderly. The data collectíon protocol tncluded socio-demographic data, Questíons to elicit Elder Abuse (Carney, Kahan B Paris, 2003 adap. By Ferreira Alves & Sousa, 2005), scale of instrumental actívi - ties of daily living Lawton and Brody and Katz index to assess the levei of independence in actívities of daily living. Objectives: To evaluate the assodation between abuse and neglect in the elderly, instrumental actívitíes of daily living and levei of independence in actívitíes of daily living. Results: Emotional abuse is signifícantty correlated with the levei of independence in activities of daity Uving (p = 0. 000), older peopie with less independence tend to have higher leveis of emotional abuse. The total abuse is signtficantly correlated with the leveis of independence in activittes of daily living (p = 0. 002), less independent elderty tend to suffer greater abuse and neglect. There were no statistically significant associations between abuse and neglect and instrumental activities of daily l1v1ng. Conclusions: The less independent elderly are more vulnerable to situatíons of abuse and neglect, being more exposed to emotional abuse. These results point to the need for health professionals/ nurses develop prevention interventions, including strategies to support carers and early screentng tn less independent elderly.

Antãoa "Polythecnic Institute o f Bragança, Bragança, Portugal; bEPI Unit, Public Health Institute, University of Porto, Portugal. Contact details: catarinaisabeln.amaraliSsmaU.com Introduction: Breast câncer is one of the most common mahgnant pathology in European countries, as Portugal, where annual inddence is around 90 new cases per 100,000 women. Breast surgery is the usual treatment for this pathology, however such procedure can be complicated by the infection of surgical site. Objectives: To know the prevalence and determtnants of surgtcal wound infection after breast surgery. Methods: We conducted a systematic review by searching of the Web of Sdence electronic database for articles published over the last s1x years 1n developed countries. Over three hundred dtatíons were obtained and after excludtng citations with reasons, fíve artícles met our inclusion criteria and were included in the present review. Results: Prevalence of surgical wound infection varied across studies between 0. 1% and 12. 5%. Bilateral mastectomy is assodated with higher prevalence of wound infectíon than unilateral mastectomy (3. 6% vs 3, 3%), lumpectomy with immediate breast reconstruction (IBR) is related with higher frequency of wound infectíon than surgery with no IBR (0, 5% vs 0, 1%), also, mastectomy with IBR is associated with higher prevalence of wound infectíon than mastectomy wtth no IBR (1, 5% vs 0, 3%) and breast surgery followed by axiltary lymph nade dissectíon is related with higher prevalence of wound infection than surgical procedures wtth no axillary lymph node dissection (2, 82% vs 1, 66%). Conclusions: Nurses that provide post-operatíve care to women after breast surgery should be aware about risk of wound tnfectíon, partícularly after more invasive procedures.

Objetivo: El propósito del estudio fue relacionar la etapa en el cambio en el comportamiento frente a la actividad física y el estado nutricional en escolares entre 9 y 17 años de Bogotá- Colombia, pertenecientes al estudio FUPRECOL. Método: Se trata de un estudio transversal, en 6.606 niños y adolescentes entre 9 y 17 años, pertenecientes a 24 instituciones educativas, de Bogotá-Colombia. Se aplicó de manera auto-diligenciada el cuestionario de cambio de comportamiento en función a la intensión de realizar actividad física (CCC-Fuprecol) y se midió el peso y la estatura para determinar el estado nutricional con el índice de masa corporal (IMC). Resultados: El porcentaje de respuesta fue 94% y se consideraron válidos 6,606 registros, siendo 58.3 % (n=3.850) niñas con un promedio de edad de 12,7±2,3 años. En la población general, el 5,3 % de los escolares se encontraban en etapa de pre-contemplación, 31,8 % en contemplación, el 26,7 % en acción y el 36,2 % en etapa de mantenimiento. Al comparar la etapa de cambio con el estado nutricional por IMC, los escolares clasificados en obesidad mostraron mayor frecuencia de respuesta en la etapa de pre-contemplación, mientras que los escolares con peso saludable acusaron mayores porcentajes en la etapa de mantenimiento. Conclusión: En escolares de Bogotá, Colombia, se encontró una relación estadísticamente significativa entre a la intensión de realizar actividad con el estado nutricional medido con el IMC. Fomentar la promoción de la actividad física y monitorear el estado nutricional, deberá ser una prioridad en las agendas y políticas públicas dentro del ámbito escolar.

El ejercicio de labores asistenciales en el personal de la salud, las largas horas de trabajo y la responsabilidad en la ejecución de sus tareas, llevan consigo la exposición a riesgos psicosociales; que de no ser debidamente controlados pueden llevar al individuo a generar respuestas inadecuadas a nivel cognitivo, emocional e intelectual, las cuales se manifiestan en algunos casos con la aparición de sintomatología osteomuscular y/o asociada al estrés. OBJETIVO Identificar la relación entre las demandas de la tarea, el control sobre las mismas y la presencia e intensidad de síntomas de estrés y osteo-musculares en médicos, especialistas y personal de enfermería de una institución hospitalaria de IV nivel en Bogotá. Métodos Estudio de corte transversal en una muestra de 100 profesionales de la salud. Se utilizaron tres instrumentos: cuestionario Nórdico para la detección y análisis de síntomas músculo esqueléticos, cuestionario Karasek para identificar la percepción del trabajo y la relación del entorno profesional y el cuestionario de Estrés del Ministerio de la Protección Social validado para la población colombiana. Se obtuvo previa autorización del Comité de Investigaciones y Comité de Ética del Hospital. El análisis estadístico se realizó con el IBM SPSS Statistics versión 2.0 Resultados Se observó que los síntomas osteomusculares con mayor prevalencia estuvieron relacionados con afectaciones en espalda 43% y cuello 36%; no se observan diferencias estadísticamente significativas entre los distintos profesionales. En cuanto a presencia de sintomatología asociada al estrés, la mayor prevalencia se presentó en síntomas osteomusculares en cuello y espalda en el 84% de los casos, dolor de cabeza en el 74%, trastornos del sueño y cansancio en el 64% y percepción de sobrecarga laboral en el 63%. Para el análisis de prevalencia de los factores psicosociales laborales se utilizó la clasificación de la combinación de altas o bajas demandas y alto o bajo control, el resultado de estos teniendo en cuenta el modelo Demanda-control fue la siguiente: trabajo de alta tensión 34%; trabajo activo 40%; trabajo aburrido 13% y trabajo pasivo 13%. Se encontró una asociación entre la sintomatología y las variables toma de decisiones en médicos especialistas (OR 3,12; IC 95%: 2,80 – 3,49) lo que ratifica que este tipo de profesional tiene una mayor libertad para generar decisiones en su actuar médico y control sobre la tarea para especialistas (OR 3,23; IC 95%: 2,82 – 3,70) y enfermeros jefes (OR 3,36; IC 95%: 2,91 – 3,89); lo que permite inferir que cada uno de estos profesionales posee las herramientas para asumir las exigencias y dar respuesta a los distintos aspectos que están ligados a la tarea. Conclusiones: La presencia de síntomas osteo musculares en zonas como cuello y espalda son propios de la actividad del personal de la salud y se asocia a las posturas inadecuadas y el puesto de trabajo, así como al estrés. En cuanto a la sintomatología asociada al estrés se ratifica la presencia de sintomatología osteo muscular (cuello y espalda), como manifestaciones asociadas al cansancio, trastornos del sueño, sobrecarga laboral, dolor de cabeza y en menor porcentaje dificultades para relacionarse con otros. Respecto a los factores de riesgo psicosocial, se observó que el trabajo activo es la condición predominante en el personal de la salud, pero se observa además que un porcentaje importante experimenta episodios de tensión laboral, asociados a condiciones propias de las demandas psicológicas y el control sobre la tarea. Por lo anterior, se deben establecer acciones encaminadas a favorecer espacios saludables, y programas tendientes a la mejora de las condiciones de tal manera que disminuya la presencia de sintomatología osteomuscular y/o sintomatología derivada del estrés.

Introducción. Los trabajadores de los talleres de reparación de automóviles conviven diariamente con la exposición a los solventes orgánicos, exposición que se convierte en un riesgo para su salud que generalmente en el corto plazo se presenta como déficits de concentración, memoria y tiempo de reacción y en el largo plazo produciendo graves repercusiones clínicas como efectos mutagénicos y carcinogénicos. Objetivo. Caracterizar las condiciones higiénicas y de seguridad de trabajadores ocupacionalmente expuestos a solventes orgánicos y determinar los niveles ambientales de benceno, tolueno y xileno (BTX) en talleres de lámina y pintura automotriz de la ciudad de Bogotá. Materiales y métodos. Se hizo un estudio de corte transversal en 60 trabajadores que laboran expuestos a solventes orgánicos en talleres de reparación automotriz en Bogotá. Se realizó una encuesta con variables sociodemográficas, laborales y se determinaron los niveles en aire de benceno, tolueno y xileno. Para los muestreos ambientales, las bombas se colocaron en una posición fija representativa del ambiente general, con el objeto de conocer la distribución de los solventes en el área de trabajo. Se realizó un análisis descriptivo por conteos de frecuencia, medidas de tendencia central y dispersión. Se utilizó prueba de bondad de ajuste para distribución normal (Kolmogorov-Smirnov o Shapiro Wilk), prueba t Student para comparación de medias, o en su defecto prueba U de Mann Whitney para comparación de medianas. Para identificar la relación entre las características sociodemográficas y ocupacionales con la exposición a BTX, se utilizaron pruebas de asociación Chi cuadrado o análisis de correlación según la naturaleza de las variables. El nivel de significancia para cada prueba fue 0.05. Resultados. La edad promedio de los trabajadores fue de 43 años y un tiempo total de exposición a solventes de 20 años. Respecto al uso de protección corporal, 45 (75%) de los trabajadores manifestaron que usaban uniforme, mientras que 14 (23,3%) usaban ropa de calle durante la jornada laboral. El 46,7% manifestaron usar protección respiratoria. La concentración de benceno en aire fue entre 0,1 y 0,45 mg/l (mediana de 0,31 mg/l; DE 0,13 mg/l); la de tolueno estuvo entre 8,25 y 27,22 mg/l (mediana de 14,5 mg/l; DE 6.99 mg/l) y la de xileno entre 19,34 y 150,15 mg/l (mediana de 70,12 mg/l; DE 40,82 mg/l). Conclusión. Los pintores de automóviles están expuestos a niveles elevados de solventes en los lugares de trabajo y no cuentan con condiciones de higiene y seguridad industrial adecuados. Un gran número de pintores son informales lo que les impide el acceso a los beneficios del Sistema de Seguridad Social Integral.
