Prevalence of nutritional risk and malnutrition in hospitalized patients: a retrospective, cross-sectional study of single-day screening.

Hospital malnutrition remains a significant public health issue, particularly in developing countries. The Global Leadership Initiative on Malnutrition (GLIM) proposed homogenizing criteria to standardize malnutrition diagnosis. This study aimed to retrospectively determine the prevalence of nutritional risk and malnutrition diagnoses among hospitalized patients using the Nutritional Risk Screening (NRS)-2002 screening instrument and the GLIM criteria, respectively. We conducted a retrospective, cross-sectional study from nutritional records of patients hospitalized in a single centre 2021. Nutrition data from records included medical diagnosis, gender, length of stay, age, weight, height, body mass index, weight loss, calf circumference, and middle upper arm circumference. Nutritional risk and malnutrition were evaluated using NRS-2002 and GLIM criteria. Its concordance was further evaluated by using a Kappa test. The study included 616 records of patients; 52.3% (n = 322) of the population were male. The prevalence of nutritional risk, according to NRS-2002, was 69.5% (n = 428). Nutritional risk as well as malnutrition diagnosis according to GLIM criteria was observed in 87.8% (n = 374) of patienttritional risk and malnutrition were evaluated using NRS-2002 and GLIM criteria. Its concordance was further evaluated by using a Kappa test. Ws. Tools showed a strong concordance (κ= 0.732). All anthropometric data, except for height, were found to be significantly different between patients with moderate and severe malnutrition (p < 0.05). Our findings highlight a high prevalence of malnutrition in this group of hospitalized patients in Mexico. NRS-2002 demonstrated good agreement with the diagnosis of malnutrition according to GLIM criteria and could be considered part of the straightforward two-step approach for malnutrition; however, further studies are needed.

Resting energy expenditure changes after antineoplastic treatment in gynecological cancer: a prospective pilot study / Cambios en el gasto energético en reposo tras el tratamiento antineoplásico en cáncer ginecológico: estudio piloto prospectivo

Introduction: energy metabolism in cancer patients is influenced by different factors. However, the effect of antineoplastic treatment is not clear, especially in women. Objective: to evaluate resting energy expenditure (REE) by indirect calorimetry (IC) before (T0) and after (T1) first cycle period of antineoplastic therapy: radiotherapy (RT), chemotherapy (CT), and concomitant chemoradiation therapy (CRT), quality of life (QoL) and accuracy of REE were compared with international guidelines recommendations per kilogram (European Society for Clinical Nutrition and Metabolism [ESPEN]). Methods: an observational, longitudinal study was conducted in women with gynecological cancer diagnosis undergoing antineoplastic treatment: RT, CT and CRT. Weight loss, actual body weight and height were measured. REE was evaluated in T0-T1 and compared with ESPEN recommendations. Kruskal-Wallis test and Bland-Alman analysis were used to determine the agreement (± 10 % of energy predicted) of REE adjusted by physical activity (TEE) compared with ESPEN recommendations, respectively. Results: fifty-four women with cancer were included: 31.5 % (n = 17) for RT group, 31.5 % (n = 17) for CT group and 37 % (n = 20) for CRT group. REE showed statistical differences between T0 and T1 in the total population (p = 0.018), but these were not associated with anticancer therapy groups (p > 0.05). QoL had no significant changes after treatment (p > 0.05). Accuracy of 25 and 30 kcal/kg compared to TEE was less than 30 %. Conclusion: REE in women with gynecological cancer decreased after antineoplastic treatments but this is not associated with a particular antineoplastic therapy. It is needed to develop research to determine the accuracy of ESPEN recommendations with TEE estimated by IC and clinical factors in women with cancer. (AU)

Antecedentes: el metabolismo energético en pacientes con cáncer está influenciado por diferentes factores. Sin embargo, el efecto sobre el tratamiento antineoplásico no es claro, especialmente en mujeres. Objetivo: evaluar el gasto energético en reposo (GER) mediante calorimetría indirecta (CI) antes (T0) y después (T1) del primer ciclo del tratamiento antineoplásico: radioterapia (RT), quimioterapia (QT) y quimio-radioterapia concomitante (QRT), calidad de vida (CdV) y precisión del GER con las con las recomendaciones internacionales por kilogramo de peso (European Society for Clinical Nutrition and Metabolism [ESPEN]). Métodos: se realizó un estudio longitudinal, observacional en mujeres con diagnóstico de cáncer ginecológico en tratamiento antineoplásico. Se evaluó el GER en T0 y T1. Se midieron la pérdida de peso, el peso corporal y la talla. Se usaron las pruebas de Kruskal-Wallis y el análisis Bland-Altman para determinar la concordancia (± 10 % de GER) del REE ajustado por actividad física (TEE) en comparación con las recomendaciones de ESPEN. Resultados: se incluyeron 54 mujeres con cáncer; 31,5 % (n = 17) en el grupo RT, 31,5 % (n = 17) en el de QT y 37 % (n = 20) en el de QRT. GER mostró diferencias estadísticas entre T0 y T1 en la población total (p = 0,018); no se asoció con la terapia contra el cáncer (p > 0,05). La calidad de vida no tuvo cambios significativos después del tratamiento (p > 0,05). La precisión de 25 y 30 kcal/kg en comparación con TEE fue inferior al 30 %. Conclusión: el GER en mujeres con cáncer ginecológico disminuyó después del tratamiento antineoplásico, pero no se asoció a una terapia antineoplásica en particular. Es fundamental desarrollar más investigaciones que compare las recomendaciones de ESPEN y con los valores de la CI comparando más factores clínicos para ofrecer una intervención nutricional precisa (AU)

Obesidad y riesgo de recaídas en pacientes con Leucemia Linfoblástica Aguda: Estudio retrospectivo

Antecedentes: La obesidad se ha asociado con estado proinflamatorio de bajo grado que se ha relacionado con el desarrollo del cáncer en general incluyendo el hematológico. Objetivos: El presente trabajo tiene el objetivo de identificar la asociación del diagnóstico de obesidad acorde al índice de masa corporal (IMC) con indicadores pronóstico de pacientes adultos con Leucemia Linfoblástica Aguda (LAL). Pacientes y Método: Se trata de un estudio observacional, retrospectivo que incluyó pacientes hospitalizados con diagnóstico de LAL de linaje de células B. Se estimó el IMC con base al peso y talla registrado al ingreso de los pacientes. Se determinó el riesgo de recaídas, recaídas a médula ósea y supervivencia. Se utilizó el método de Kaplan-Meier mediante el test log-Rank en el análisis estadístico. Resultados: Se incluyeron 128 pacientes. El peso y el IMC no mostraron una asociación significativa con el riesgo de recaídas. La frecuencia de recaída a médula ósea fue del 43,8%. La obesidad no impactó con la supervivencia global (p = 0,640) ni en la supervivencia libre de enfermedad (p = 0,527). La presencia de obesidad no se comportó como una variable de riesgo de recaída (p = 0,873). El IMC con punto de corte de 30 kg/m2 no se comportó como un factor de riesgo de recaída (OR 1.078). Conclusión: La obesidad no es un factor de riesgo independiente para el pronóstico de los pacientes adultos portadores de Leucemia Linfoblástica Aguda de linaje B.

Background: Obesity has been associated with a low-grade proinflammatory state, and it has been related to the development of cancer in general, including hematologic cancer. Aim: The present work aimed to identify the association of the diagnosis of obesity according to the body mass index (BMI) with prognostic factors of adult patients with Acute Lymphoblastic Leukemia (ALL). Patients and Method: This observational, retrospective study included hospitalized patients diagnosed with ALL of the B-cell lineages. BMI was estimated based on the weight and height registered on clinical records at the admission of the patients. The relapse risk and bone marrow relapse were determined, and the survival rate was measured. The statistical analysis included the Kaplan-Meier method using the log-Rank test. Results: This study included 128 clinical records of patients. Weight had no significant association with relapse risk. The frequency of bone marrow relapse was 43.8%. Obesity did not impact overall survival (p = 0.640) or disease-free survival (p = 0.527). The presence of obesity does not behave as a relapse risk variable (p = 0.873). BMI with a 30 kg/m2 cut-off point did not influence relapse risk (OR 1.078). Conclusion: Obesity is not an independent risk factor for the prognosis of adult patients with Acute Lymphoblastic Leukemia B-lineage.

COVID-19 in a country with a very high prevalence of diabetes: The impact of admission hyperglycaemia on mortality.

Aims: To evaluate the frequency of diabetes and admission hyperglycaemia in Mexican COVID-19 patients, to describe the clinical and biochemical characteristics of patients with admission hyperglycaemia and to determinate the impact of diabetes and admission hyperglycaemia on COVID-19 severity and mortality. Methods: A multicentric study was performed in 480 hospitalized patients with COVID-19. Clinical and biochemical characteristics were evaluated in patients with admission hyperglycaemia and compared with non-hyperglycaemic patients. The effect of diabetes and admission hyperglycaemia on severity and risk of death were evaluated. Results: Age was 50.7 ± 13.6 years; 68.3% were male. Some 48.5% (n = 233) had admission hyperglycaemia; 29% (n = 139) of these patients had pre-existing diabetes. Patients with admission hyperglycaemia had more requirement of invasive mechanical ventilation (IMV), higher levels of urea, D-dimer and neutrophil-lymphocyte ratio (NLR), as well as lower lymphocyte count. An association between admission hyperglycaemia with IMV and D-dimer with glucose was found. Age ≥50 years (OR 2.09; 95%CI 1.37-3.17), pre-existing diabetes (OR 2.38; 95%CI 1.59-5.04) and admission hyperglycaemia (OR 8.24; 95%CI 4.74-14.32) were risk factors for mortality. Conclusions: Admission hyperglycaemia is presented in 48.5% of COVID-19 patients. Diabetes and admission hyperglycaemia are associated with the severity of disease and mortality. This study shows the devastating conjunction of hyperglycaemia and COVID-19. Clinical trial registration: Clinical characteristics of patients with COVID-19, DI/20/204/04/41 (Hospital General de Mexico) and NR-13-2020 (Hospital Regional de Alta Especialidad Ixtapaluca).

Cost-effectiveness of artificial intelligence monitoring for active tuberculosis treatment: A modeling study.

BACKGROUND: Tuberculosis (TB) incidence in Los Angeles County, California, USA (5.7 per 100,000) is significantly higher than the U.S. national average (2.9 per 100,000). Directly observed therapy (DOT) is the preferred strategy for active TB treatment but requires substantial resources. We partnered with the Los Angeles County Department of Public Health (LACDPH) to evaluate the cost-effectiveness of AiCure, an artificial intelligence (AI) platform that allows for automated treatment monitoring. METHODS: We used a Markov model to compare DOT versus AiCure for active TB treatment in LA County. Each cohort transitioned between health states at rates estimated using data from a pilot study for AiCure (N = 43) and comparable historical controls for DOT (N = 71). We estimated total costs (2017, USD) and quality-adjusted life years (QALYs) over a 16-month horizon to calculate the incremental cost-effectiveness ratio (ICER) and net monetary benefits (NMB) of AiCure. To assess robustness, we conducted deterministic (DSA) and probabilistic sensitivity analyses (PSA). RESULTS: For the average patient, AiCure was dominant over DOT. DOT treatment cost $4,894 and generated 1.03 QALYs over 16-months. AiCure treatment cost $2,668 for 1.05 QALYs. At willingness-to-pay threshold of $150K/QALY, incremental NMB per-patient under AiCure was $4,973. In univariate DSA, NMB were most sensitive to monthly doses and vocational nurse wage; however, AiCure remained dominant. In PSA, AiCure was dominant in 93.5% of 10,000 simulations (cost-effective in 96.4%). CONCLUSIONS: AiCure for treatment of active TB is cost-effective for patients in LA County, California. Increased use of AI platforms in other jurisdictions could facilitate the CDC's vision of TB elimination.

Usefulness of the neutrophil-to-lymphocyte, monocyte-to-lymphocyte and lymphocyte-to-platelet ratios for the prognosis of COVID-19-associated complications.

INTRODUCTION: Various biomarkers based on blood counts have been useful for the prognosis of patients critically ill with COVID-19. OBJECTIVE: To describe the usefulness of the neutrophil-to-lymphocyte (NLR), monocyte-to-lymphocyte (MLR) and lymphocyte-to-platelet (LPR) ratios for the prognosis of mortality and ventilatory support requirement for COVID-19. METHOD: Retrospective cohort of clinical records of patients with COVID-19 who required hospital care. RESULTS: One-hundred and -twenty-five cases were analyzed; mean age was 51 years, and 60 % were of the male gender; 21.6 % had type 2 diabetes mellitus, and 18.4 % had hypertension. Mean leukocyte count was 9.5 x 103/µL, with a neutrophil mean of 8.0 x 103/µL. Mean NLR was 12.01, while for MLR it was 0.442, and for LPR, 373.07. Regarding the area under the curve, the following values were recorded for mortality: 0.594 for NLR, 0.628 for MLR and 0.505 for LPR; as for mechanical ventilation, the values were 0.581 for NLR, 0.619 for MLR and 0.547 for LPR. In the univariate analysis, an NLR value > 13 (OR: 2.750, p = 0.001) and an MLR of > 0.5 (OR: 2.069, p = 0.047) were associated with mortality; LPR showed no impact on mortality or respiratory support. CONCLUSION: NLR and MLR are useful for predicting mortality in patients with COVID-19.

Implicaciones en el movimiento humano de las adaptaciones del esquema e imagen corporal secundarias a una amputación / Implications in human movement of the adjustments about the scheme and body image as an outcome of an amputation

Introducción: el movimiento corporal humano es el resultado de la interacción entre elementos psicológicos, biológicos y sociales. Las amputaciones generan alteraciones en la estructura mental del individuo ocasionando restricciones en la participación social; por ello, es necesario comprender la influencia de la imagen y el esquema corporal de los sujetos con amputación según la teoría del movimiento continuo. Métodos: se realizó una revisión de la literatura en las bases de datos PubMed, Science Direct, Clinical Key, PEDro, SciELO en el mes de abril de 2020; la selección de artículos se dividió en 3 fases, utilizando los términos"body schema", "body image", "amputee" y "movement".Resultados: se encontró un total de 142 artículos, de los cuales se incluyeron 13 que cumplían con los criterios de selección. Discusión: posterior a una amputación se producen alteraciones de la imagen y el esquema corporal, además de cambios plásticos en el sistema nervioso central; derivado de esto existirán modificaciones en el movimiento corporal de la persona.Se requiere favorecer el manejo integral del sujeto con amputación basado en la teoría del movimiento continuo abarcando esferas psicológicas, biológicas y sociales. Conclusión: la aceptación e integración de la imagen y esquema corporal son fundamentales para restablecer la capacidad máxima de movimiento de la persona con amputación.

Introduction: Human body movement is the result of the interaction among psychological, biological and social elements; ampu-tations generate alterations in the individual's mental structure causing restrictions on social participation; therefore, it is necessary to understand the influence of the image and body schema of amputee subjects according to the theory of continuous movement. Methods:A review of the literature was carried out in the databases PubMed, Science Direct, Clinical Key, PEDro, SciELO in April 2020; the selection of articles was divided into 3 phases, using the terms "body schema", "body image", "amputee" and "movement". Results: A total of 142 articles were found, of which 13 that met the selection criteria were included. Discussion: After an amputation, alterations of the image and body schema will occur. In addition to plastic changes in the central nervous system, therefore will be modifications in the person's body movement. It is necessary to favor the comprehensive management of the subject with amputation based on the theory of continuous movement, covering psychological, biological and social spheres. Conclusion: The acceptance and integration of the image and body schema are fundamental to reestablish the maximum capacity of movement of the person with amputation

Thyroid hormones in ovarian follicular fluid: Association with oocyte retrieval in women undergoing assisted fertilization procedures.

OBJECTIVE: Our aim was to analyze the role of thyroid hormones in follicular fluid (FF) in relation to the number of oocytes retrieved in women recruited for an assisted fertilization procedure. METHODS: Retrospective cohort study of 51 women 37.5±3.3 years, range 29-42, evaluated after a controlled ovarian stimulation protocol in a University Hospital. FF was sampled by transvaginal ultrasound-guided aspiration after ovarian hyperstimulation and we measured T3 (T3f), T4 (T4f), TSH (TSHf) and free T4 (T4ff). The oocyte maturation rate was calculated as: Number of metaphase II oocytes/Number of oocytes retrieved x 100. Statistical analysis was performed using the SPSS-19 software. RESULTS: Hormone levels in FF were: TSHf 1.3µIU/ml (0.4 - 2.7), T3f: 1.52±0.46 nmol/L, T4f 88.8±30.9nmol/L and T4ff: 15.44±2.57pmol/L. The number of oocytes recovered was dependent onT4f following the equation: Log (oocyte) = 0.379+0.042*T4f (r:0.352, p=0.012). After a logistic regression model analysis, T3f showed a tendency to be associated with the OMR: OR (95 % CI)= 0.977 (0.954 to 1.001), p=0.057. CONCLUSIONS: The correlation found between thyroid hormones and the number of oocytes retrieved suggests an interaction between thyroid and gonadal axes in relation to follicular development.

Improved Mucosal Wave in Unilateral Autologous Temporal Fascia Graft in Sulcus Vocalis Type 2 and Vocal Scars.

OBJECTIVES/HYPOTHESIS: We analyzed the results of 10 patients treated by unilateral autologous temporal fascia graft, comparing the pre and post surgery results, as well as the appearance of the wave and the intervals until the re-appearance of it. STUDY DESIGN: Retrospective, clinical case series. METHODS: Subjective and objective evaluation was preoperatively and postoperatively performed, using laryngovideostroboscopy, the Voice Handicap Index-10, GRBAS (grade, roughness, breathiness, asthenia, and strain), harmonics to noise ratio, Jitter, Shimmer, phonatory range, maximum phonation time, and S/Z ratio in all patients. Postoperative visits were scheduled after 1 week, 1 month, at 3 months, and at 6 months after the surgery. RESULTS: After surgery, we found significant differences in the maximum phonation time and the S/Z ratio (P <0.05). Most parameters of GRBAS also improved significantly, both in general and in the subscales, except for Breathiness and Asthenia (P <0.05). There was an average decrease in Voice Handicap Index-10 of 11.2 (P <0.05). At laryngovideostroboscopy, the mucous wave reappeared in all patients treated 1 month after surgery, and increased in amplitude until 6 months postoperative.

Entertainment-Education Narrative Versus Nonnarrative Interventions to Educate and Motivate Latinas to Engage in Mammography Screening.

BACKGROUND: The evidence is limited comparing the effects of entertainment-education (E-E) narrative versus nonnarrative interventions to educate and motivate Latinas to engage in mammography screening. AIMS: This study compared an E-E narrative intervention to two nonnarrative interventions' effects among Latinas on breast cancer knowledge and motivation, as measured by changes in self-efficacy, behavioral norms, and behavioral intentions to engage in mammography screening. METHOD: A sample of 141 Spanish-speaking Latinas was randomly assigned to one of three arms: an E-E narrative video, a nonnarrative educational video, and printed educational materials. Using a repeated measures design, the influence of the E-E narrative on pretest to posttest measures was assessed and compared to the influence of the other two interventions. RESULTS: The E-E narrative and nonnarrative interventions significantly increased Latinas' breast cancer knowledge, mammography self-efficacy, and behavioral norms from pretest to posttest. However, the E-E narrative participants' pretest to posttest difference in mammography self-efficacy was significantly higher when compared to the difference of the other two interventions. The effect of the E-E narrative intervention on self-efficacy and behavioral norms was moderated by the participants' absorption in the story and identification with the story characters. CONCLUSION: E-E narrative and nonnarrative interventions significantly educated and motivated Latinas to engage in mammography screening. The effects on mammography self-efficacy, an important precursor to behavior change, can be more strongly influenced by E-E narratives. DISCUSSION: Although E-E narrative and nonnarrative interventions were effective, the need still exists to assess if they can ultimately influence lifesaving breast cancer screening behaviors.

Thyroxin Is Useful to Improve Sperm Motility.

BACKGROUND: The aim of this study was to evaluate the non-genomic action of thyroxin on sperm kinetic and its probable use to improve sperm recovery after applying an en- richment method like "swim-up" in comparison with the available one, pentoxifylline. MATERIALS AND METHODS: This is an experimental study. A total of 50 patients were re- cruited, followed by infertility consultation. Conventional sperm assays were performed according to World Health Organization criteria-2010 (WHO-2010). A Computer Aided Semen Analysis System was employed to assess kinetic parameters and concentrations. Number of the motile sperm recovered after preparation technique was calculated. RESULTS: Addition of T4 (0.002 µg/ml) to semen samples increased hypermotility at 20 minutes (control: 14.18 ± 5.1% vs. 17.66 ± 8.88%, P<0.03, data expressed as mean ± SD) and remained unchanged after 40 minutes. Significant differences were found in the motile sperm recovered after swim-up (control: 8.93×10(6) ± 9.52× 06vs. 17.20×10(6) ± 21.16×10(6), P<0.03), achieving all of the tested samples a desirable threshold value for artificial insemination outcome, while adding pentoxifylline increased the number of recovered sperm after swim-up in 60% of the studied cases. No synergism between two treatments could be determined. CONCLUSION: We propose a new physiological tool to artificially improve insemination. The discussion opens windows to investigate unknown pathways involved in sperm ca- pacitation and gives innovative arguments to better understand infertility mechanisms.

Prevalencia de enfermedades tiroideas en una población del área metropolitana de Buenos Aires / Prevalence of thyroid diseases in a population of the metropolitan area of Buenos Aires

La prevalencia de alteraciones morfológicas palpables tiroideas no supera el 8% en la población adulta. En el Hospital de Clínicas de la Universidad de Buenos Aires se llevó a cabo un programa gratuito para la detección de enfermedades tiroideas, convocándose a sujetos que desconocieran antecedentes tiroideos. Nuestro objetivo fue establecer la frecuencia de patología morfológica palpable tiroidea, en una población seleccionada de pacientes, y comparar dichos resultados con los hallazgos de un programa de detección similar, realizado en el año 2001¹. Adicionalmente, evaluar la prevalencia de alteraciones funcionales y de autoinmunidad tiroidea. Los individuos que concurrieron se dividieron en 3 grupos: Grupo 1 (n = 186) pacientes con antecedentes personales de enfermedad tiroidea conocida (excluidos del análisis); Grupo 2 (n = 184) sujetos con antecedentes familiares, otras enfermedades autoinmunes, o sintomatología que pudiera atribuirse a alteración de la función tiroidea (grupo inducido), y Grupo 3 (n = 288) sujetos que consultaron por mera curiosidad (grupo random). La función y autoinmunidad tiroidea se evaluó en 144 participantes del Grupo 3, citados al azar. En el grupo random, la prevalencia de alteraciones morfológicas tiroideas, detectadas por palpación, fue del 11,09%. Al comparar estos resultados con los obtenidos 12 años atrás en un estudio similar, realizado en nuestro hospital, no se encontraron diferencias estadísticamente significativas (8,7 vs. 11,09%; p = 0,25). En cuanto a la función tiroidea, se halló hipotiroidismo subclínico en el 6,25%, hipertiroidismo subclínico en el 0,7% y autoinmunidad en el 11% de los sujetos evaluados. En conclusión, la prevalencia de alteraciones palpables de la glándula tiroides no cambió en laúltima década. Esta investigación realizada en una población correctamente seleccionada constituye una herramienta útil para referencias futuras como población control en Argentina.

The prevalence of palpable thyroid morphological abnormalities does not exceed 8% in the adult population. A free program was conducted in the Hospital de Clínicas (University of Buenos Aires) for the detection of thyroid diseases, inviting subjects who were unaware of a history of these diseases. The aim was to establish the frequency of goitre in the selected population, as well as to evaluate the prevalence of functional disorders and thyroid autoimmunity, and to compare these results with the findings of a similar study performed in 2001¹. The subjects were divided into three groups: Group 1 (n = 186) patients with a history of previously known thyroid disorders (excluded subjects); Group 2 (n = 184) subjects with a family history of thyroid disease, other autoimmune diseases, or symptoms that could be attributed to changes in thyroid function (Induced Group), and Group 3 (n = 288) subjects who participated in this program due to mere curiosity (Random Group). Autoimmunity and thyroid function was assessed in 144 randomly selected participants in Group 3. In Group 3, the prevalence of morphological alterations of the thyroid gland was 11.09%. Comparing these results with those obtained 12 years ago in a similar study performed in our hospital, no statistically significant differences were found when the prevalence of morphological thyroid alterations were compared (8.7% vs 11.09%, p=.25). As for thyroid function, subclinical hypothyroidism was found in 6.25%, subclinical hyperthyroidism in 0.7%, and autoimmunity in 11% of subjects evaluated. It was concluded that the prevalence of palpable thyroid abnormalities had not change in the last decade. This study, made in a correctly selected population, is a useful tool for future reference as a control population in Argentina.

Perceptions of QOL among caregivers of Mexican ancestry of adults with advanced cancer.

PURPOSE: There is a substantial gap in the literature about the perceptions of QOL of caregivers of Mexican ancestry. This qualitative study explores the role of culture on the perceptions of QOL of this understudied population. METHODS: Twenty caregivers providing care to adults with advanced cancer were interviewed. Thematic analysis identified several themes for each domain of QOL, including physical, psychological, social, and spiritual domains and the role of culture. RESULTS: Cultural background influenced all of the QOL domains. There was a tremendous synergy across domains of physical, psychological, social, and spiritual well-being. Extended family and religious beliefs, life experiences, and culture were important components of QOL for these caregivers. Cultural expectations influenced role functioning and caregiver burden. CONCLUSION: This study informs our understanding of the role of culture on perceptions of QOL. Future investigations should be conducted with other Latino subgroups to describe QOL and to determine the role of culture on perceived QOL. Interventions should be specifically designed to improve caregivers' QOL and to reduce the burden of cancer in this underserved population.

Exploring the influence of demographic and medical characteristics of African-American and Latinas on enrollment in a behavioral intervention study for breast cancer survivors.

PURPOSE: To better understand research participation among hard-to-reach populations, this exploratory investigation examined characteristics of enrollees and non-enrollees from a population-based longitudinal study with African-American and Latina-American breast cancer survivors. METHODS: A mixed-method recruitment approach was utilized to enroll participants from cancer registries and community groups who were 1-6 years post-diagnosis. RESULTS: Four hundred and sixty-eight participants agreed to participate constituting an 81% participation rate; 65 and 55% completed Time-1, and both Time-1 and Time-2 assessments, respectively. African-Americans were more likely to agree to participate and complete the T1 assessment (73%) than Latinas (62%) (p < 0.05). Participation was influenced by educational attainment and comorbidities (p < 0.05) for African-Americans. Among Latinas, language proficiency, comorbidities and psychological difficulties (p < 0.01) influenced participation. CONCLUSIONS: Our findings suggest that enrollment in research studies may be influenced by complex and multi-dimensional factors stemming from subjects' characteristics including ethnicity, culture, language proficiency and literary, and socioeconomic status, as well as medical characteristics including co-occurring chronic illness and psychological status. Thus, comprehensive, multi-method research studies are urgently needed to better understand and address the challenge of minority recruitment in biomedical research. To increase research participation among cancer survivors, it is imperative to implement focused strategies that will support and encourage individuals' enrollment and continued participation in studies.

The cancer caregiving experience of caregivers of Mexican ancestry.

The act of providing care may be the same in all ethnic groups, but the way caregiving is defined by family members is influenced by cultural values and beliefs. This study describes the caregiving experience and challenges of caregivers of Mexican ancestry. Qualitative interviews of 20 family caregivers and thematic analysis of transcribed audiotapes identified four themes that characterized their caregiving experience. These themes include an emphasis on family values, a strong commitment to care, difficulties dealing with everyday life realities, and a reliance on spirituality, all of which added to the meaningfulness and burden of caregiving. Further investigation within a cultural context is warranted in the development of interventions and programs to better assist caregivers in coping with the challenges of providing cancer care.

Association between testosterone levels and the metabolic syndrome in adult men.

OBJECTIVE: To evaluate the relationship between testosterone levels and the metabolic syndrome (MS) in men older than 45 years. METHODS: Six hundred and sixty men (45-70 years) selected from 2906 participants of a population screening for prostate cancer were included in this study. Testosterone and the components of MS were assessed in all men. MS was diagnosed according to NCEP-ATP III criteria. Triglycerides (TG)/HDL-cholesterol (chol) index was calculated. RESULTS: The presence of MS was inversely associated with testosterone (χ2, p < 0.001), independently of age (OR 0.802, CI 95%: 0.724-0.887, p < 0.0001). Hypertension was the most frequent abnormality observed followed by elevated TG and waist circumference (WC). Testosterone correlated positively with HDL-chol (r: 0.14, p < 0.0001) and negatively with body mass index (BMI)(r: -0.29, p < 0.0001), WC (r: -0.26, p < 0.0001), TG (r: -0.20, p < 0.0001), TG/HDL-chol (r: -0.20, p < 0.0001), glucose (r: -0.11, p = 0.005) and MS score (r: -0.23, p < 0.0001). CONCLUSIONS: Our results show that in men older than 45 years, as long as testosterone levels decline, the prevalence of MS increases, independently of age. The correlations found between testosterone and four of the five components of MS, as well as with BMI and TG/HDL-chol ratio, a surrogate marker of insulin resistance, suggest considering male hypogonadism as a determinant of developmental abnormalities typical of MS.

Quality of cancer follow-up care: a focus on Latina breast cancer survivors.

INTRODUCTION: Receiving quality cancer follow-up care influences survivorship outcomes. Among Latinas, breast cancer is the number one cause of cancer death; yet Latinas do not receive adequate follow-up care. This study examined quality of cancer follow-up care among Latina breast cancer survivors (BCS) and whether it differs by participant language and healthcare system variables (provider specialty, and medical setting). METHODS: Two hundred thirty-two (95 English-speaking Latina and 137 Spanish-speaking) Latina BCS were recruited from the California Cancer Registry, hospital cancer registries, and community agencies. RESULTS: English-speaking Latina BCS were more likely to report receiving cancer follow-up care at a doctor's office (p < 0.001). BCS without a regular place for cancer follow-up care were more likely to report not seeing a primary care provider (p < 0.05) or cancer specialist (p < 0.001) in the past 12 months. English-speaking Latina BCS (p < 0.001), BCS who saw a cancer specialist in the past 12 months (p < 0.001), and received follow-up care at a doctor's office (p < 0.05) reported higher quality of care. Speaking English, having seen a cancer specialist, and receiving follow-up care at a doctor's office were independently associated with higher quality of care, explaining 44 % of the variance. CONCLUSIONS: Our study findings suggest that examining the influence of ethnic and linguistic factors on quality of cancer follow-up care is necessary to address health disparities. Improved access to cancer follow-up care for Spanish-speaking Latina BCS is of particular concern. IMPLICATION OF CANCER SURVIVORS: Identifying follow-up care needs of Latina BCS may contribute to providing high-quality care and improved survivorship outcomes.
