Quality of life, symptom experience, and use of complementary and alternative medicine among women with ovarian cancer

The objectives of this dissertation were to determine the quality of life in women with ovarian cancer and the association of their physical and emotional well-being with the number of symptoms, duration of symptoms, and the scores of common symptoms of ovarian cancer; to study the prevalence of complementary and alternative medicine techniques for symptom relief and its association with the number of symptoms, age, education, insurance, comorbidity, and satisfaction with medical care they received, and their pre-diagnostic experience of symptoms.^ This study was based on a secondary data analysis of a study of early detection of ovarian cancer. A sample of 139 women with ovarian cancer was recruited and was administered a questionnaire comprised of questions on their quality of life, their symptoms and what they did about the symptoms, whether they used any complementary and alternative medicine techniques, and other medical conditions they had. Out of this sample, 53 patients underwent in-depth interviews relating to their symptoms before the diagnosis and their experiences with the health care system leading to the ovarian cancer diagnosis. ^ In article #1, ovarian cancer patients were observed to have significantly poorer quality of life on all subscales and summary scores except pain, compared to that of the general population of US women. Physical well-being scores were negatively associated with the number of symptoms before diagnosis and a significant negative association of comorbidity index was observed with physical well-being. Higher education and increase in time since diagnosis was found to have better physical scores. Emotional well-being scores showed marginally significant associations with number of symptoms and bloating. ^ In article #2, a thematic content analysis of the ovarian cancer patients’ interviews revealed that on recognition of their symptoms women first assumed their symptoms to be a normal transient occurrence due to a pre-existing disease condition, or due to some other disease. A series of misattributions of their symptoms on their and their doctors’ part impacted their health care seeking.In article #3, a significantly greater likelihood of CAM use with an increase in the number of symptoms was observed.^ Based on the foregoing results, it is important to educate women on possible signs of ovarian cancer and also to educate doctors about the results of current research regarding ovarian cancer diagnosis. This will help to avoid a delay in getting a diagnosis and improve women’s quality of life. It emphasizes the diagnosis of ovarian cancer in earlier stages by more sensitive screening techniques. This study emphasizes the importance of consideration of comorbidity in any quality of life research. Additionally, educating women in the safe use of CAM techniques carries immense significance because the efficacy and safety of many of the currently advertized CAM products has not been scientifically validated. Further research is needed to confirm the findings of this study. ^

Posttraumatic stress disorder among veterans of the Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) wars: Psychological comorbidities, postdeployment social support and unit support

Much attention has been given to treating Operation Iraqi Freedom/Operation Enduring (OIF/OEF) Veterans with posttraumatic stress disorder (PTSD). However, little attention is given to those Veterans who do not meet diagnostic criteria for PTSD but who may still benefit from intervention. Research is needed to investigate the impact of how different racial/ethnic backgrounds, different levels of social support and comorbid mental health disorders impact OIF/OEF Veterans with varying levels of PTSD. The purpose of this dissertation is to examine the association of comorbid Axis I disorders, race/ethnicity, different levels of postdeployment social support and unit support on OIF/OEF Veterans with varying levels of PTSD. Data for this dissertation were from postdeployment screenings of OIF/OEF Veterans from a large Veterans Affairs hospital in southeast Texas. To examine the study hypotheses, we conducted multinomial logistic regressions of the clinician reported data. ^ The first article examined the prevalence of subthreshold and full levels of PTSD and compared Axis I and alcohol use comorbidity rates among 1,362 OIF/OEF Veterans with varying levels of PTSD. Results suggest that OIF/OEF Veterans with subthreshold PTSD experience similar levels of psychological distress as those with full PTSD and highlight the need to provide timely and appropriate mental health services to individuals who may not meet the diagnostic criteria for full PTSD. ^ These results suggest that OIF/OEF Veterans of all race/ethnicities can benefit from strong social support systems. Postdeployment social support was found to be a protective factor against the development of PTSD among White, Black and Hispanic veterans while deployment unit support was a protective factor only among Black Veterans. The second article investigated the association between postdeployment social support and unit support with varying levels of PTSD by race/ethnicity among 1,115 OIF/OEF Veterans. ^ The results of this study can help to formulate treatment and interventions for OIF/OEF Veterans with varying levels of PTSD and social support systems.^

Trastuzumab use and risk of congestive heart failure in older breast cancer patients

Trastuzumab is a humanized-monoclonal antibody, developed specifically for HER2-neu over-expressed breast cancer patients. Although highly effective and well tolerated, it was reported associated with Congestive Heart Failure (CHF) in clinical trial settings (up to 27%). This leaves a gap where, Trastuzumab-related CHF rate in general population, especially older breast cancer patients with long term treatment of Trastuzumab remains unknown. This thesis examined the rates and risk factors associated with Trastuzumab-related CHF in a large population of older breast cancer patients. A retrospective cohort study using the existing Surveillance, Epidemiology and End Results (SEER) and Medicare linked de-identified database was performed. Breast cancer patients ≥ 66 years old, stage I-IV, diagnosed in 1998-2007, fully covered by Medicare but no HMO within 1-year before and after first diagnosis month, received 1st chemotherapy no earlier than 30 days prior to diagnosis were selected as study cohort. The primary outcome of this study is a diagnosis of CHF after starting chemotherapy but none CHF claims on or before cancer diagnosis date. ICD-9 and HCPCS codes were used to pool the claims for Trastuzumab use, chemotherapy, comorbidities and CHF claims. Statistical analysis including comparison of characteristics, Kaplan-Meier survival estimates of CHF rates for long term follow up, and Multivariable Cox regression model using Trastuzumab as a time-dependent variable were performed. Out of 17,684 selected cohort, 2,037 (12%) received Trastuzumab. Among them, 35% (714 out of 2037) were diagnosed with CHF, compared to 31% (4784 of 15647) of CHF rate in other chemotherapy recipients (p<.0001). After 10 years of follow-up, 65% of Trastuzumab users developed CHF, compared to 47% in their counterparts. After adjusting for patient demographic, tumor and clinical characteristics, older breast cancer patients who used Trastuzumab showed a significantly higher risk in developing CHF than other chemotherapy recipients (HR 1.69, 95% CI 1.54 - 1.85). And this risk is increased along with the increment of age (p-value < .0001). Among Trastuzumab users, these covariates also significantly increased the risk of CHF: older age, stage IV, Non-Hispanic black race, unmarried, comorbidities, Anthracyclin use, Taxane use, and lower educational level. It is concluded that, Trastuzumab users in older breast cancer patients had 69% higher risk in developing CHF than non-Trastuzumab users, much higher than the 27% increase reported in younger clinical trial patients. Older age, Non-Hispanic black race, unmarried, comorbidity, combined use with Anthracycline or Taxane also significantly increase the risk of CHF development in older patients treated with Trastuzumab. ^

Impact of racial differences in medical care on breast cancer survival: Findings from a large nationwide and retrospective cohort study

Background: No studies have attempted to determine whether nodal surgery utilization, time to initiation and completion of chemotherapy or surveillance mammography impact breast cancer survival. ^ Objectives and Methods: To determine whether receipt of nodal surgery, initiation and completion of chemotherapy, and surveillance mammography impact of racial disparities in survival among breast cancer patients in SEER areas, 1992-2005. ^ Results: Adjusting for nodal surgery did not reduce racial disparities in survival. Patients who initiated chemotherapy more than three months after surgery were 1.8 times more likely to die of breast cancer (95% CI 1.3-2.5) compared to those who initiated chemotherapy less than a month after surgery, even after controlling for known confounders or controlling for race. Despite correcting for chemotherapy initiation and completion and known predictors of outcome, African American women still had worse disease specific survival than their Caucasian counterparts. We found that non-whites underwent surveillance mammography less frequently compared with whites and mammography use during a one- or two-year time interval was associated with a small reduced risk of breast-cancer-specific and all-cause mortality. Women who received a mammogram during a two-year interval could expect the same disease-specific survival benefit or overall survival benefit as women who received a mammogram during a one-year interval. We found that while adjustment for surveillance mammography receipt and physician visits reduced differences in mortality between blacks and whites, these survival disparities were eliminated after adjusting for the number of surveillance mammograms received. ^ Conclusions: The disparities in survival among African American and Hispanic women with breast cancer are not explained by nodal surgery utilization or chemotherapy initiation and chemotherapy completion. Surveillance mammograms, physician visits and number of mammograms received may play a major role in achieving equal outcomes for breast cancer-specific mortality for women diagnosed with primary breast cancer. Racial disparities in all-cause mortality were explained by racial differences in surveillance mammograms to certain degree, but were no longer significant after controlling for differences in comorbidity. Focusing on access to quality care and post treatment surveillance might help achieve national goals to eliminate racial disparities in healthcare and outcomes. ^

Assessing the patterns of colorectal cancer treatment, adherence to treatment guidelines and survival in Texas

Colorectal cancer (CRC) is the third leading cancer in both incidence and mortality in Texas. This study investigated the adherence of CRC treatment to standard treatment guidelines and the association between standard treatment and CRC survival in Texas. The author used Texas Cancer Registry (TCR) and Medicare linked data to study the CRC treatment patterns and factors associated with standard treatment in patients who were more than 65 years old and were diagnosed in 2001 through 2007. We also determined whether adherence to standard treatment affect patients' survival. Multiple logistic regression and Cox regression analysis were used to analyze our data. Both regression models are adjusted for demographic characteristics and tumor characteristics. We found that for the 3977 regional colon cancer patients 80 years old or younger, 60.2% of them received chemotherapy, in adherence to the recommended treatment guidelines. People with younger age, female gender, higher education and lower comorbidity score are more likely adherent to this surgery guideline. Patients' adherence to chemotherapy in this cohort have better survival compared to those who are not (HR: 0.76, 95% CI: 0.68-0.84). For the 12709 colon cancer patients treated with surgery, 49.3% have more than 12 lymph nodes removed, in adherence to the treatment guidelines. People with younger age, female gender, higher education, regional stage, lager tumor size and lower comorbidity score are more likely to adherent to this surgery guideline. Patients with more than 12 lymph nodes removed in this cohort have better survival (HR: 0.86, 95% CI: 0.82-0.91). For the 1211 regional rectal cancer patients 80 years old or younger, 63.2% of them were adherent to radiation treatment. People with smaller tumor size and lower comorbidity score are more likely to adherent to this radiation guideline. There is no significant survival difference between radiation adherent patients and non-adherent patients (HR: 1.03, 95% CI: 0.82-1.29). For the 1122 regional rectal cancer patients 80 years old or younger who were treated with surgery, 76.0% of them received postoperative chemotherapy, in adherence to the treatment guidelines. People with younger age and smaller comorbidity score are related with higher adherence rate. Patients adherent with adjuvant chemotherapy in this cohort have better survival than those were not adherent (HR: 0.60, 95% CI: 0.45-0.79).^

Hippocampal atrophy in recurrent major depression.

Hippocampal volumes of subjects with a history of major depressive episodes but currently in remission and with no known medical comorbidity were compared to matched normal controls by using volumetric magnetic resonance images. Subjects with a history of major depression had significantly smaller left and right hippocampal volumes with no differences in total cerebral volumes. The degree of hippocampal volume reduction correlated with total duration of major depression. In addition, large (diameter > or = 4.5 mm)-hippocampal low signal foci (LSF) were found within the hippocampus, and their number also correlated with the total number of days depressed. These results suggest that depression is associated with hippocampal atrophy, perhaps due to a progressive process mediated by glucocorticoid neurotoxicity.

Capacidade funcional e saúde bucal relacionada à qualidade de vida de idosos

É de extrema importância estudar a relação entre capacidade funcional e saúde bucal relacionado à qualidade vida, para auxiliar nos fatores intervenientes tanto no cuidado odontológico como em outras áreas de atenção à saúde do idoso, além de adequar planos de tratamento as reais necessidades de cada indivíduo, proporcionando melhor qualidade de vida. O objetivo desse estudo foi investigar a capacidade funcional e saúde bucal relacionada à qualidade de vida do idoso. Foram incluídos na pesquisa idosos acima de 65 anos que residem em área de cobertura da Estratégia Saúde da Família de Bauru. Foram investigadas, através de entrevistas, as variáveis capacidade funcional (Índice de Katz), saúde bucal relacionada à qualidade de vida (OHIP-14), condições socioeconômicas e comorbidades. Foram excluídos da pesquisa idosos que apresentavam alterações de compreensão e expressão da comunicação, Para a realização da análise estatística foi utilizado o Teste de Pearson ao nível de significância de 0,05 e a Regressão Linear Multivariada, ao nível de significância de p 0,01. Participaram da pesquisa 238 idosos com 65 anos ou mais, sendo que 56,3% tinham entre 65 e 74 anos e 43,7% tinham 75 anos ou mais, a média geral de idade foi 74,5 anos. Quanto ao sexo, 55,5% eram mulheres, houve predominância da raça branca (65,1%). Quanto a variável capacidade funcional, 8,8% apresentaram incapacidade funcional intermediária ou severa. Sobre os aspectos socioeconômicos, 61,3% dos idosos apresentaram renda mensal de até dois salários mínimos, 88,2% eram aposentados ou pensionistas, 68,9% tinham algum grau de escolaridade e 57,1% eram casados ou mantinham uma união estável. Quanto a saúde bucal relacionada à qualidade de vida, 20,6% dos entrevistados se sentiram desconfortáveis para mastigar alguns tipos de alimentos. A hipertensão arterial foi a comorbidade mais relatada pelos entrevistados (75,6%). As dimensões dificuldade para mastigar (0,21; p<0,05) e necessidade de parar as refeições (0,21; p<0,05) do instrumento OHIP-14 apresentaram correlação estatisticamente significante com o Índice de Katz. Através da análise multivariada, foi observado que quanto maior a incapacidade menos o idoso se preocupa com a saúde bucal. A alimentação é um aspecto importante da vida diária de qualquer pessoa, especialmente o idoso que apresenta doenças crônicas em maior quantidade e severidade conforme o envelhecimento acontece. Além disso, a incapacidade apresentou tendência de aumento com a idade, no entanto a literatura não permite concluir que o envelhecimento em si seja causa da incapacidade funcional. A maior limitação do estudo se relaciona ao próprio desenho epidemiológico, pois o estudo transversal não permite inferências de causalidade, no entanto a amplitude do grupo etário nesta pesquisa permite observar tendências sobre a capacidade funcional e a saúde bucal relacionada à qualidade de vida em idosos. A incapacidade funcional aumentou com a idade e apresentou tendência de maior impacto negativo na saúde bucal relacionada a qualidade de vida dificultando a realização de refeições.

Variáveis associadas a não adesão à terapia medicamentosa em idosos hipertensos e com comorbidades de uma unidade pública de saúde de Ribeirão Preto-SP

A adesão ao tratamento ocorre quando o conselho médico ou de saúde coincide com o comportamento do indivíduo, ao uso de medicamentos, cumprimento da dieta e mudanças no estilo de vida, não sendo, portanto, um ato não passivo do paciente. Em pacientes com hipertensão arterial sistêmica a adesão ao tratamento pode ser definida como o grau de cumprimento das medidas terapêuticas indicadas, sejam elas medicamentosas ou não, com o objetivo de manter a pressão arterial em níveis pressóricos normais. A não adesão em pacientes com doenças crônicas em tratamento a longo prazo em países desenvolvidos é em média de 50%, revelando a importância de serem avaliados os motivos que levam a esse comportamento. O estudo teve como objetivo avaliar a não adesão em idosos hipertensos de uma unidade pública de saúde de Ribeirão Preto - SP. Trata-se de um estudo de corte transversal, desenvolvido com uma amostra de 196 pessoas. A coleta de dados ocorreu entre agosto de 2014 até junho de 2015, após aprovação do Comitê de Ética em Pesquisa. Para essa etapa foram utilizados os instrumentos Brief Medication Questionnaire, Medical Outcomes Studies 36-item Short Form Survey, Escore de Risco Global e Escore de Risco pelo Tempo de Vida. Após a coleta dos dados, as entrevistas foram codificadas, os dados foram tabulados e foi realizada a análise estatística descritiva e de correlação. Como resultado, constatou-se que houve predomínio de mulheres, com idade média de 69,4 anos, casados/união estável, não moravam sozinhos, com 1,85 pessoas na casa em média, de cor branca, com ensino fundamental incompleto, renda de até dois salários mínimos e aposentados/pensionistas, atendidos pelo SUS. Apresentaram hábitos de vida razoáveis, sem predomínio de consumo de bebidas alcoólicas, tabagismo, uso excessivo de sal e sedentarismo. A mais frequente comorbidade associada à HAS foi a dislipidemia. Foi observado elevado predomínio de fatores de risco cardiovasculares como obesidade abdominal, obesidade geral, comorbidades, razão de lipídeos e fatores agravantes como proteína c reativa ultrassensível, microalbuminúria e síndrome metabólica. A maioria da amostra foi classificada como sendo portador de risco cardiovascular alto após estratificação do risco. A percepção da qualidade de vida relacionada à saúde foi considerada baixa na maioria principalmente devido a limitações emocionais. A não adesão esteve presente em quase metade dos idosos, relacionada principalmente à complexidade da farmacoterapia e dificuldade em lembrar sobre o uso de seus medicamentos. Não foi observada correlação entre a não adesão e as variáveis estudadas. Conclui-se que o comportamento de não adesão observado não esteve relacionada às variáveis estudadas nessa amostra e que são necessárias intervenções urgentes para reduzir o risco cardiovascular e prevenir doenças cardiovasculares e mortalidade, bem como melhora da percepção da qualidade de vida relacionada à saúde.

Molecular Genetic Basis of Opposite Gene by Environment Interactions in Reading Disability and Attention Deficit/Hyperactivity Disorder

The goal of this study is to better understand the genetic basis of Reading Disability (RD) and Attention Deficit Hyperactivity Disorder (ADHD) by examining molecular G x E interactions with parental education for each disorder. Research indicates that despite sharing genetic risk factors, RD and ADHD are influenced by different types of G x E interactions with parental education - a diathesis stress interaction in the case of ADHD and a bioecological interaction in RD. In order to resolve this apparent paradox, we conducted a preliminary study using behavioral genetic methods to test for G x E interactions in RD and the inattentive subtype of ADHD (ADHD-I) in the same sample of monozygotic and dizygotic Colorado Learning Disabilities Research Center same-sex twin pairs (DeFries et al., 1997), and our findings were consistent with the literature. We posited a genetic hypothesis for this opposite pattern of interactions, which suggests that only genes specific to each disorder enter into these opposite interactions, not the shared genes underlying their comorbidity. This study sought to further investigate this paradox using molecular genetics methods. We examined multiple candidate genes identified for RD or related language phenotypes and those identified for ADHD for G x E interactions with parental education. The specific aims of this study were as follows: 1) partition known risk alleles for RD and/or related language phenotypes and ADHD-I into those which are pleiotropic and non-pleiotropic by testing each risk allele for association with both RD and ADHD-I, 2) explore the main effects of parental education on both RD and ADHD-I, 3) address G-E correlations, and 4) conduct exploratory G x E interaction analyses in order to test the genetic hypothesis. Analyses suggested a number of pleiotropic genes that influence both RD and ADHD; however, results did not remain after correcting for multiple comparisons. Although exploratory G x E interaction findings were not significant after multiple comparison correction, results suggested a G x E interaction in the bioecological direction with KIAA0319, parental education, and ADHD-I. Given the limited power in the current study, replication of these findings with larger samples is necessary.

The Lighter Side of Anorexia.

Anorexia nervosa is a disorder characterized by ego-syntonic self-starvation and is associated with impairment in functioning, emotional distress, psychiatric comorbidity, and an elevated mortality risk. Evidence-based data on treatment interventions for anorexia nervosa are scarce despite the need for more targeted and effective treatments. This paper offers an integrative model using humor as a therapeutic intervention for the treatment of anorexia nervosa. It proposes that the integration and application of humor in psychotherapy can be a powerful adjunct in treatment because it has the potential to activate change in the physiological, cognitive, emotional, and interpersonal realms negatively affected by this disorder.

Evaluación del bienestar espiritual en pacientes en hemodiálisis

Introducción: Se define la espiritualidad como la búsqueda personal de propósito y significado en la vida, pudiendo incorporar o no la religión. En este artículo se presenta el desarrollo y la aplicación de una medida de bienestar espiritual a una muestra de pacientes en hemodiálisis. Material y métodos: El instrumento básico empleado se denomina Cuestionario del Sentido de la Vida (Meaning in Life Scale, MiLS), con 21 ítems y cuatro escalas: Propósito, Falta de significado, Paz y Beneficios de la espiritualidad. También se proporciona una puntuación global de espiritualidad. Además, se registraron variables de tipo clínico (tiempo en hemodiálisis, índice de comorbilidad de Charlson) y sociodemográfico (edad, género), así como estimaciones del estado de salud, calidad de vida (general y actual), felicidad personal, el grado de religiosidad y la creencia en la existencia de vida ultraterrena. Se ha utilizado un diseño transversal con 94 pacientes en hemodiálisis. Resultados: Los resultados muestran que la versión española de este instrumento (MiLS-Sp) es una medida de bienestar espiritual con garantías psicométricas de calidad (fiabilidad, validez), adecuada para evaluar las complejas exigencias generadas por la problemática de salud del paciente en hemodiálisis. El bienestar espiritual se relaciona significativamente con diversas variables de calidad de vida, percepción de salud, felicidad personal o religiosidad. No existe una relación significativa entre las puntuaciones de espiritualidad y la edad, el sexo, el tiempo en diálisis o el índice de comorbilidad. El grado de bienestar espiritual de estos pacientes es relativamente bajo. Conclusión: La espiritualidad parece desempeñar un papel importante en el bienestar psicológico, el estado de salud y la calidad de vida percibidos por el paciente en hemodiálisis. El grado de bienestar espiritual de estos pacientes es relativamente bajo. Estos resultados sugieren que considerar y evaluar el grado de bienestar espiritual en los pacientes en hemodiálisis puede ser de utilidad para la práctica clínica.
