Sarcopenia and sarcopenic obesity among community-dwelling Peruvian adults: A cross-sectional study.

INTRODUCTION: Sarcopenia and sarcopenic obesity (SO) have emerged as significant contributors to negative health outcomes in the past decade. We aimed to estimate the prevalence of probable sarcopenia, sarcopenia, and SO in a community-dwelling population of 1151 adults aged ≥55 years in Lima, Peru. METHODS: This cross-sectional study was conducted between 2018 and 2020. Sarcopenia was defined as the presence of low muscle strength (LMS) and low muscle mass (LMM) according to European (EWGSOP2), US (FNIH) and Asian (AWGS2) guidelines. We measured muscle strength by maximum handgrip strength and muscle mass using bioelectrical impedance analyzer. SO was defined as a body mass index ≥ 30 kg/m2 and sarcopenia. RESULTS: The study participants had a mean age of 66.2 years (SD 7.1), age range between 60 to 92 years old, of which 621 (53.9%) were men. Among the sample, 41.7% were classified as obese (BMI ≥30.0 kg/m²). The prevalence of probable sarcopenia was estimated to be 22.7% (95%CI: 20.3-25.1) using the EWGSOP2 criteria and 27.8% (95%CI: 25.2-30.4) using the AWGS2 criteria. Sarcopenia prevalence, assessed using skeletal muscle index (SMI), was 5.7% (95%CI: 4.4-7.1) according to EWGSOP2 and 8.3% (95%CI: 6.7-9.9) using AWGS2 criteria. The prevalence of sarcopenia based on the FNIH criteria was 18.1% (95%CI: 15.8-20.3). The prevalence of SO, considering different sarcopenia definitions, ranged from 0.8% (95%CI: 0.3-1.3) to 5.0% (95%CI: 3.8-6.3). CONCLUSION: Our findings reveal substantial variation in the prevalence of sarcopenia and SO, underscoring the necessity for context-specific cut-off values. Although the prevalence of SO was relatively low, this result may be underestimated. Furthermore, the consistently high proportion of probable sarcopenia and sarcopenia point to a substantial public health burden.

Correlation between Instrumental Activities of Daily Living and muscle mass in older adults: impact of comorbidities.

Background: There is evidence that sarcopenia and functionality are closely related. However, the association between geriatric syndromes, such as dependence, on instrumental activities and sarcopenia could be affected by the presence of certain comorbidities, such as overweight, obesity, diabetes, and chronic obstructive pulmonary disease (COPD). Therefore, the present study aimed to determine the association between instrumental activities of daily living and muscle mass in the elderly and evaluate the impact of certain comorbidities on this association. Methods: This was a retrospective analytical observational study, including 1897 patients. Muscle mass was measured with calf circumference, and instrumental activities were measured with the Lawton index. Results: Among different parameters studies, a statistical correlation was found in a stratified regression analysis between the Lawton index score and muscle mass in patients who were overweight (p value:0.001 ;beta coefficient: 0.08), obese (p value: 0.001 ; beta coefficient: 0.05), had diabetes (p value: 0.012 ;beta coefficient: 0.03), and had COPD (p value:0.001 ;beta coefficient:0.03). Conclusion: The correlation between muscle mass and instrumental activities of daily living should be evaluated individually according to the needs of each participant and according to their comorbidities, promoting patient-centered geriatric medicine.

Evaluation of factors influencing handgrip strength asymmetry in elderly Peruvians.

Background: Sarcopenia is a musculoskeletal disease involving the reduction of muscle mass, strength, and performance. Handgrip strength (HGS) measurements included in frailty assessments are great biomarkers of aging and are related to functional deficits. We assessed the association between potential influencing factors and HGS asymmetry in older Peruvian adults. Methods: We used a database of the Peruvian Naval Medical Center "Cirujano Santiago Távara" located in Callao, Peru. All the patients included were ≥60 years old and had an HGS measurement in the dominant and non-dominant hand. Results: From a total of 1468 patients, 74.66% had HGS asymmetry. After adjustment, calf circumference weakness (aPR = 1.08, 95% CI = 1.01 - 1.15), falls risk (aPR = 1.08, 95% CI = 1.02 - 1.16), and an altered Lawton index (aPR = 0.92, 95% CI = 0.84 - 0.99) were associated with HGS asymmetry. Conclusion: Our findings suggest that HGS asymmetry should be measured along with other geriatric assessments used to evaluate health outcomes in the elderly to enhance health promotion and prevention aimed at preserving muscle strength to curb functional limitations in the elderly.

Acute abdomen following COVID-19 vaccination: a systematic review.

Purpose: Conduct a systematic review of case reports and case series regarding the development of acute abdomen following coronavirus disease 2019 (COVID-19) vaccination, to describe the possible association and the clinical and demographic characteristics in detail. Materials and Methods: This study included case report studies and case series that focused on the development of acute abdomen following COVID-19 vaccination. Systematic review studies, literature, letters to the editor, brief comments, and so forth were excluded. PubMed, Scopus, EMBASE, and Web of Science databases were searched until June 15, 2023. The Joanna Briggs Institute tool was used to assess the risk of bias and the quality of the study. Descriptive data were presented as frequency, median, mean, and standard deviation. Results: Seventeen clinical case studies were identified, evaluating 17 patients with acute abdomen associated with COVID-19 vaccination, which included acute appendicitis (n=3), acute pancreatitis (n=9), diverticulitis (n=1), cholecystitis (n=2), and colitis (n=2). The COVID-19 vaccine most commonly linked to acute abdomen was Pfizer-BioNTech (messenger RNA), accounting for 64.71% of cases. Acute abdomen predominantly occurred after the first vaccine dose (52.94%). All patients responded objectively to medical (88.34%) and surgical (11.76%) treatment and were discharged within a few weeks. No cases of death were reported. Conclusion: Acute abdomen is a rare complication of great interest in the medical and surgical practice of COVID-19 vaccination. Our study is based on a small sample of patients; therefore, it is recommended to conduct future observational studies to fully elucidate the underlying mechanisms of this association.

Sarcopenia and sarcopenic obesity among community-dwelling Peruvian adults: A cross-sectional study.

Background: Sarcopenia and sarcopenic obesity (SO) have emerged as significant contributors to negative health outcomes in the past decade. However, there remains a lack of consensus on the criteria and cut-off thresholds for assessing sarcopenia and SO. Moreover, limited data are available on the prevalence of these conditions in Latin American countries. To address this evidence gap, we aimed to estimate the prevalence of probable sarcopenia, sarcopenia, and SO in a community-dwelling population of 1151 adults aged ≥ 55 years in Lima, Peru. Methods: Data collection for this cross-sectional study was conducted between 2018 and 2020 in two urban low-resource settings in Lima, Peru. Sarcopenia was defined as the presence of low muscle strength (LMS) and low muscle mass (LMM) according to European (EWGSOP2), US (FNIH) and Asian (AWGS) guidelines. We measured muscle strength by maximum handgrip strength; muscle mass using a whole-body single-frequency bioelectrical impedance analyzer, and physical performance using the Short Physical Performance Battery and 4-meter gait speed. SO was defined as a body mass index ≥ 30 kg/m2 and sarcopenia. Results: The study participants had a mean age of 66.2 years (SD 7.1), of which 621 (53.9%) were men, and 41.7% were classified as obese (BMI ≥ 30.0 kg/m2). The prevalence of probable sarcopenia was estimated to be 22.7% (95%CI: 20.3-25.1) using the EWGSOP2 criteria and 27.8% (95%CI:25.2-30.4) using the AWGS criteria. Sarcopenia prevalence, assessed using skeletal muscle index (SMI), was 5.7% (95%CI: 4.4-7.1) according to EWGSOP2 and 8.3% (95%CI: 6.7-9.9) using AWGS criteria. The prevalence of sarcopenia based on the FNIH criteria was 18.1% (95%CI: 15.8-20.3). The prevalence of SO, considering different sarcopenia definitions, ranged from 0.8% (95%CI: 0.3-1.3) to 5.0% (95%CI: 3.8-6.3). Conclusions: Our findings reveal substantial variation in the prevalence of sarcopenia and SO when using different guidelines, underscoring the necessity for context-specific cut-off values. Nevertheless, regardless of the chosen guideline, the prevalence of probable sarcopenia and sarcopenia among community-dwelling older adults in Peru remains noteworthy.

Discontinuation of Antihypertensive Drug Use Compared to Continuation in COVID-19 Patients: A Systematic Review with Meta-analysis and Trial Sequential Analysis.

INTRODUCTION: COVID-19 related mortality is about 2%, and it increases with comorbidities, like hypertension. Regarding management, there is debatable evidence about the benefits of continuation vs. discontinuation of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers (ACEI/ARB). AIM: We performed a systematic review to assess the effects and safety of in-hospital discontinuation compared to continuation of ACEI/ARB in COVID-19 patients. METHODS: We systematically searched on PubMed, Scopus, and EMBASE from inception to June 19, 2021. We included observational studies and trials that compared the effects and safety of continuing ACEI/ARB compared to discontinuing it in COVID-19 patients. Effects sizes for dichotomous variables were expressed as risk ratios (RR) and 95% confidence intervals. For continuous variables, effects were expressed as mean difference (MD). We used random effect models with the inverse variance method. We assessed certainty of evidence using the GRADE approach. RESULTS: We included three open-label randomized controlled trials and five cohort studies. We found that the continuation group had lower risk of death compared with the discontinuation group only in the cohort group (RR: 0.46, 95% CI: 0.24-0.90), but not in the RCT group (RR: 1.22, 95% CI: 0.75-2.00). The ICU admission rate was significantly lower in the continuation group (RR: 0.46, 95% CI: 0.31-0.68) in the cohort group, but not in RCT group (RR: 1.03, 95% CI: 0.67-1.59). We did not find significant differences between groups regarding hospitalization length, hypotension, AKI needing renal replacement therapy, mechanical ventilation, new or worsening heart failure, myocarditis, renal replacement therapy, arrhythmias, thromboembolic events and SOFA AUC. The GRADE approach revealed that the certainty ranged from moderate to high level. CONCLUSIONS: There is no significant difference in mortality and other outcomes between continuation and discontinuation groups.

Factors associated with mortality in patients hospitalized for COVID-19 admitted to a tertiary hospital in Lambayeque, Peru, during the first wave of the pandemic.

INTRODUCTION: COVID-19 caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has spread worldwide, becoming a long-term pandemic. OBJECTIVES: To analyze the factors associated with mortality in patients hospitalized for COVID-19 in a tertiary hospital in the Lambayeque region of Peru. METHODS: A retrospective cohort study of patients with a diagnosis of COVID-19, hospitalized in a hospital in northern Peru, was conducted from March to September 2020. RESULTS: Of the 297 patients studied, 69% were women, the mean age was 63.99 years (SD = ±15.33 years). Hypertension was the most frequent comorbidity (36.67%), followed by diabetes mellitus (24.67%) and obesity (8.33%). The probability of survival at 3 days of ICU stay was 65.3%, at 7 days 24.2%, and 0% on day 14. Risk factors associated with mortality in patients hospitalized for COVID-19 are age, male sex, tachypnea, low systolic blood pressure, low peripheral oxygen saturation, impaired renal function, elevated IL-6 and elevated D-dimer. CONCLUSIONS: Mortality in hospitalized patients with COVID-19 was 51.18 per 100 persons, Mortality was found to be associated with hypertension, type of infiltrating, and sepsis.

Self-Medication Practices, Use of Brand-Name, and Over-the-Counter Medicines by Peruvian Older Adults.

Background: Older adults are a particularly vulnerable group to drug use and self-medication. The aim of the study was to evaluate self-medication as a factor associated with the purchase of brand-name and over-the-counter (OTC) drugs in older adults in Peru. Methods: A secondary analysis was performed using an analytical cross-sectional design of data from a nationally representative survey from 2014 to 2016. The exposure variable was self-medication, defined as the purchase of medicines without a prescription. The dependent variables were purchases of brand-name and OTC drugs, both as a dichotomous response (yes/no). Information of sociodemographic variables, health insurance, and the types of drugs purchased by the participants was collected. Crude prevalence ratios (PR) were calculated and adjusted using generalized linear models of the Poisson family, considering the complex sample of the survey. Results: In this study, 1,115 respondents were evaluated, with a mean age of 63.8 years and a male proportion of 48.2%. The prevalence of self-medication was 66.6%, while the proportions of purchases of brand-name and OTC drugs were 62.4% and 23.6%, respectively. The adjusted Poisson regression analysis revealed an association between self-medication and the purchase of brand-name drugs (adjusted PR [aPR]=1.09; 95% confidence interval [CI]: 1.01-1.19). Likewise, self-medication was associated with the purchase of OTC medications (aPR=1.97; 95%CI: 1.55-2.51). Conclusions: This study evidenced a high prevalence of self-medication in Peruvian older adults. Two-thirds of the surveyed people bought brand-name drugs, whereas one-quarter bought OTC drugs. Self-medication was associated with a greater likelihood of buying brand-name and OTC drugs.

Fuerza de prensión débil y su asociación con la dependencia funcional y el rendimiento físico alterado en adultos mayores de 80 años

Introducción: La fuerza de prensión débil suele ser un marcador de dependencia funcional y pobre rendimiento físico, sin embargo, esta asociación es controversial en adultos mayores de 80 años. Objetivo: Determinar la asociación entre la fuerza de prensión y la dependencia funcional y rendimiento físico entre adultos mayores de 80 años. Métodos: El presente estudio es de tipo analítico transversal, fue realizado en 147 sujetos pertenecientes a la Marina de Guerra del Perú. Evaluamos la fuerza muscular, el rendimiento físico, la funcionalidad, las medidas antropométricas y la valoración nutricional. Resultados: Encontramos una asociación significativa entre la fuerza de prensión débil y la dependencia para actividades básicas de la vida diaria (ORa: 2,81, IC95%: 1,32 a 10,11), así como el rendimiento físico alterado (ORa: 4,32, IC95%: 1,97 a 9,59), dichas asociaciones fueron independientes de la edad, número de comorbilidades, síndromes geriátricos, hemoglobina, ferritina, glucosa, colesterol total, linfocitos, vitamina b12, triglicéridos, albúmina sérica, puntaje de MMSE, circunferencia de pantorrilla, circunferencia braquial, IMC, grado de instrucción, estado civil, sexo y índice cintura/cadera. Conclusiones: En los participantes mayores de 80 años, tener una fuerza de prensión débil estuvo asociada con tener fuerza muscular débil y pobre rendimiento físico. Nuestros resultados podrían ser útiles para la inclusión de estas medidas dentro de protocolos de atención hacia poblaciones de edad avanzada y alta comorbilidad. Con ello, se busca mejorar la integridad y atención de los pacientes geriátricos.

Introduction: Weak grip strength is a well-known associated factor with disability and physical performance, but this association is controversial in older adults aged 80 years or more. Objective: To determine the association between prehensile strength and functional dependence and physical performance among adults older than 80 years. Methods: This research was an analytical, cross-sectional study, conducted in 147 older adults aged 80 years or more, from Naval Peruvian Service. We included assessments about muscle strength, physical performance, disability, anthropometric variables, and nutritional assessment. Results: We found a significant association between weak grip strength and dependence for basic activities of daily living (aOR: 2.81, 95% CI: 1.32 to 10.11), as well as altered physical performance (aOR: 4.32, 95% CI: 1.97 to 9.59), these associations were independent of age, number of comorbidities, geriatric syndromes, hemoglobin, ferritin, glucose, total cholesterol, lymphocytes, vitamin B12, triglycerides, serum albumin, MMSE score, calf circumference, brachial circumference, BMI, level of education, marital status, sex, and waist/hip ratio. Conclusions: In persons older than 80 years, having weak grip strength was associated with weak muscle strength and poor physical performance. Our results could be useful for the inclusion of these measures within care protocols for elderly and high comorbidity populations. With this, it seeks to improve the integrity and care of geriatric patients.

Association between the body mass index, waist circumference, and body fat percentage with erosive esophagitis in adults with obesity after sleeve gastrectomy.

Background: High anthropometric indexes before sleeve gastrectomy (SG) are associated with an increased risk of erosive esophagitis (EE) in bariatric surgery candidates. Reasons that explain how these indexes influence the development of esophageal pathology after surgery remains unclear. Objectives: To assess the association between the body mass index (BMI), waist circumference (WC), and body fat percentage (BFP) with the development of EE in adults with obesity three months after SG. Setting: Clínica Avendaño, Lima, Peru. Methods: Retrospective cohort using a database including adults with obesity who underwent SG during 2017-2020. All the patients included had an endoscopy before and after the surgery. Sociodemographic, clinical and laboratory characteristics were compared according to BMI, WC and BFP, as well as by the development of de novo esophagitis. The association was evaluated by crude and adjusted generalized linear models with the log-Poisson family. Results: From a total of 106 patients, 23 (21.7%) developed EE. We did not find significant differences in sociodemographic, clinical and laboratory characteristics between patients with de novo EE compared to those who did not develop EE. After adjustment, BMI (aRR = 0.59, 95% CI = 0.18-1.40), BFP (aRR = 0.41, 95% CI = 0.15-1.19) and WC (aRR = 0.91, 95% CI = 0.69-1.16) were not associated with the development of EE three months post SG. Conclusions: We found no association between preoperative anthropometric indexes and the development of de novo EE; therefore, morbid obesity should not be a criterion to exclude the patients to undergo SG as primary surgery because of the risk of developing EE.

Competencias sobre geriatría, modalidad de enseñanza y ageísmo en estudiantes de medicina en el contexto de la pandemia por COVID-19

Introducción. La pandemia por COVID-19 forzó a cambiar la educación médica a una modalidad virtual. Esta puede influenciar sobre la calidad de la enseñanza y la percepción que tienen los alumnos sobre los adultos mayores. Objetivo. Evaluar la percepción del auto reporte de cumplimiento de las competencias sobre geriatría (ACCG) y ageísmo, en estudiantes de medicina de universidades de Lima que llevaron el curso de geriatría en modalidad presencial y virtual. Métodos. Estudio transversal en estudiantes de 3 universidades de Lima, Perú que llevaron el curso de geriatría de forma presencial o virtual. El auto reporte de cumplimiento de competencias en geriatría fue medido mediante un puntaje y el ageísmo fue medido con la escala UCLA-GAS. Se realizó el análisis bivariado entre ACCG y el resto de las variables, finalmente se construyó un modelo de regresión lineal. Resultados. Se encontraron las medias del puntaje para ACCG fue de 0,72 (DE = 0,22) para la modalidad presencial y 0,75 (DE = 0,23) para la enseñanza virtual. No encontramos asociación estadística entre las variables de estudio (p = 0,39). La regresión lineal de auto reporte de cumplimiento de competencias en geriatría y ageísmo, fue ajustado por año de la carrera en que cursó geriatría y existencia de otro curso que aborde temas de geriatría, y se encontró que a mayor ACCG, mayor ageísmo. Conclusiones. Hasta el momento, no se puede afirmar que la educación virtual sea inferior a la presencial en lo que respecta generar al cumplimiento auto reportado de competencias en geriatría.

Introduction. The current COVID-19 pandemic has forced medical education to change to a virtual modality. This can influence the quality of teaching and the perception that students have about older adults. Objective. Our objective is to evaluate the perception of the self-report fulfillment of geriatric competencies (SRFGC) in medical students from universities in Lima-Peru, comparing face-to-face and virtual techniques. Methods. A cross-sectional study was designed including students from 3 universities in Lima, Peru who have taken the geriatrics course in person or virtually, measuring the main variables such as ACCG according to the recommendations of the pogoe web portal and ageing the UCLA-GAS scale. Averages and standard deviations were calculated for numerical variables and frequency for categorical variables. Bivariate analysis was also performed between ACCG and the rest of the variables measured. Results. Means 0.72 (SD=0.22) were found for the face-to-face modality and 0.75 (SD=0.23) for virtual teaching. We found no statistical association between the study variables (p value = 0.39), so there is no difference between the SRFGC between the virtual and face-to-face modalities. Through a linear regression model of SRFGC and ageism adjusted to statistically significant variables of the study, it was found that the greater the SRFGC, the greater the ageism. Conclusions. So far, it cannot be said that virtual education is inferior to face-to-face education with regard to the SRFGC.

Type 2 diabetes mellitus and hypertension as predictors of community-acquired pneumonia in Peruvian older adults with cancer

Objective: To evaluate DM2 and hypertension as predictors of CAP in older adults with cancer. Material and Methods: We conducted a secondary data analysis of a prospective cohort study in older adults with cancer from the Geriatrics Service of the Centro Médico Naval (CEMENA) of Peru during 2013-2015. T2DM and hypertension diagnosis were obtained from medical records. CAP was defined according to clinical and radiological diagnostic criteria and it was collected from the medical records of the patients up to one year after their inclusion in the study. We used the statistical software STATA v14.0 to develop the analysis. We performed multivariate analysis using crude and adjusted Cox regression models. The reported measure was the hazard ratio (HR) with their respective 95% confidence intervals (95%CI). Results: A total of 231 older adults with cancer were analyzed. The mean age of the participants was 78.6 ± 4.2 (range: 74-92 years) and all of them were men. 33 (14.29%) patients developed CAP during the follow-up, 53 (21.65%) had hypertension, and 56 (22.65%) T2DM. CAP was more frequent in patients with lung cancer and lymphomas. In the adjusted Cox regression models, we found T2DM (aHR=1.49; 95%CI: 1.21-1.79) and hypertension (aHR=1.32; 95%CI: 1.24-1.50) were predictors of CAP incidence. Conclusion: T2DM and hypertension were associated with CAP incidence in oncogeriatric patients. Future intervention studies are needed to improve the functionality and prevent CAP in this vulnerable population.

Objetivo: Evaluar la DM2 y la hipertensión como predictores de NAC en adultos mayores con cáncer. Materiales y métodos: Se realizó un análisis de base secundaria de una cohorte prospectiva en adultos mayores con diagnóstico de cáncer del Servicio de Geriatría del Centro Médico Naval (CEMENA) del Perú durante 2013-2015. Los diagnósticos de DM2 e hipertensión se obtuvieron de las historias clínicas. La NAC se definió según criterios diagnósticos clínicos y radiológicos y se recogió de las historias clínicas de los pacientes hasta un año después de su inclusión en el estudio. Utilizamos el software estadístico STATA v14.0 para desarrollar el análisis. Realizamos un análisis multivariante utilizando modelos de regresión de Cox crudos y ajustados. La medida reportada fue la razón de hazards (HR) con sus respectivos intervalos de confianza del 95% (IC95%). Resultados: Se analizaron un total de 231 adultos mayores con cáncer. La edad media de los participantes fue de 78,6 ± 4,2 (rango: 74-92 años) y todos ellos eran hombres. 33 (14,29%) pacientes desarrollaron NAC durante el seguimiento, 53 (21,65%) tenían hipertensión y 56 (22,65%) DM2. La NAC fue más frecuente en pacientes con cáncer de pulmón y linfomas. En los modelos de regresión de Cox ajustados se encontró que tener DM2 (HRa=1,49; IC95%: 1,21-1,79) o hipertensión arterial (HRa=1,32; IC95%: 1,24-1,50) fueron predictores para la incidencia de NAC. Conclusiones: La DM2 y la hipertensión se asociaron con la incidencia de NAC en pacientes oncogeriátricos. Son necesarios futuros estudios de intervención para mejorar la funcionalidad y prevenir la NAC en esta población vulnerable.

Never Thought I was Going to be Placed in a Situation Like This: In the Shoes of the Doctor Responsible for Municipal Health, Back in My Country, Perú.

The COVID-19 pandemic changed the way of living on the planet and, in my case, revealed the fragility of primary care services to respond to a health emergency that mainly affected older adults. Upon obtaining my medical degree, I felt guaranteed to have the skills to be a primary care physician; however, the coronavirus gave me "a reality bath with the aroma of impotence, bewilderment, and abandonment." Contradictory provisions and regulations, absence of a continuous policy, poor leadership, insufficient resources, and mismanagement by the Ministry of Health. Scandals of possible corruption and vices in the processes of research studies on vaccines. Anti-vaccine strategies, screening tests without evidence. The reference hospitals without oxygen, intensive care beds, and the outpatient consultations of specialist doctors closed. A community that is organized and wants to help but does not have a clear technical guide. These are some of the things I have had to deal with as head of a municipal health program. Meanwhile, I watched helplessly as members of my community continued to die and become disabled. Learning from mistakes and horrors is our duty. I narrate this experience to contribute to being prepared for the next time.

Cognitive Frailty as a Predictor of Mortality in Older Adults: A Longitudinal Study in Peru.

Objective: To evaluate the role of cognitive frailty and its components as risk factors of mortality in older adults of the Centro Médico Naval (CEMENA) in Callao, Peru during 2010-2015. Methods: We performed a secondary analysis of data from a prospective cohort that included older adults (60 years and older) treated at the CEMENA Geriatrics service between 2010-2015. Frailty was defined as the presence of three or more criteria of the modified Fried Phenotype. Cognitive impairment was assessed using the Peruvian version of the Mini Mental State Examination (MMSE), considering a score <21 as cognitive impairment. Cognitive frailty was defined as the coexistence of both. In addition, we included sociodemographic characteristics, medical and personal history, as well as the functional evaluation of each participant. Results: We included 1,390 older adults (mean follow-up: 2.2 years), with a mean age of 78.5 ± 8.6 years and 59.6% (n = 828) were male. Cognitive frailty was identified in 11.3% (n = 157) and 9.9% (n = 138) died during follow-up. We found that cognitive frailty in older adults (aHR = 3.57; 95%CI: 2.33-5.49), as well as its components, such as sedentary behavior and cognitive impairment (aHR = 7.05; 95%CI: 4.46-11.13), weakness and cognitive impairment (aHR = 6.99; 95%CI: 4.41-11.06), and exhaustion and cognitive impairment (aHR = 4.51; 95%CI: 3.11-6.54) were associated with a higher risk of mortality. Conclusion: Cognitive frailty and its components were associated with a higher risk of mortality in older adults. It is necessary to develop longitudinal studies with a longer follow-up and that allow evaluating the effect of interventions in this vulnerable group of patients to limit adverse health outcomes, including increased mortality.

Asociación entre dependencia funcional y calidad de vida en pacientes adultos mayores oncológicos / Association between functional dependence and quality of life in older adult oncology patients

RESUMEN Introducción: La presencia de comorbilidades modula el proceso de envejecimiento, el diagnóstico de cáncer puede comprometer de manera importante la salud del adulto mayor, lo cual repercute en su calidad de vida. Objetivo: Determinar la asociación entre la dependencia funcional y la calidad de vida en pacientes oncológicos adultos mayores tratados con radioterapia. Métodos: Estudio analítico retrospectivo, realizado en 181 pacientes ambulatorios del Centro Médico Naval del Callao, Perú, varones, mayores de 60 años. Se valoró la dependencia funcional mediante los índices de Barthel y el de Lawton; y la calidad de vida mediante la escala de calidad de vida en adultos mayores de la Organización Mundial de la Salud (WHOQoL-Old). Resultados: Se encontró asociación estadísticamente significativa entre dependencia funcional y calidad de vida, tanto para las actividades básicas de la vida diaria (PR= 1,04 [IC 95 %; 1,01-1,07]) como para las actividades instrumentales de la vida diaria (PR= 1,08 (IC 95 %: 1,01 - 1,13). Conclusiones: En los pacientes adultos mayores oncológicos tratados con radioterapia, se encuentra asociación significativa entre dependencia funcional y una pobre calidad de vida.
