Agreement analysis and associated factors of SARC-F and SARC-CALF in screening of risk sarcopenia in people living with human immunodeficiency virus.

Introduction: People Living with Human Immunodeficiency Virus (PLHIV) appear to be at a higher risk of developing sarcopenia. Various factors seem to influence the risk of sarcopenia, and its prevalence may differ depending on the screening tool used. This study aimed to (i) Screen the risk of sarcopenia in PLHIV using the SARC-F and SARCCalf and identify associated factors; (ii) Analyze the agreement between the instruments in PLHIV.

Frailty or sarcopenia: which is a better indicator of mortality risk in older adults?

Background: Despite the different conditions, frailty and sarcopenia overlap regarding their common link: the assessment of walking speed and muscle strength. This study aimed to compare the frailty phenotype to the sarcopenia using different cut-off points for low grip strength to determine which better identifies mortality risk over a 14-year follow-up period.

Methods: 4597 participants in the English Longitudinal Study of Ageing.

Factors of food choice and nutritional intake of Brazilian older adults according sociodemographic and health characteristics.

The rapid demographic transition in developing countries has always posed a challenge for the social and economic policies of these nations. The increase in longevity poses new challenges for understanding dietary consumption among different age groups at the old age population. The aim of this study was to evaluate the reasons for food choice and the composition of nutritional intake of older adults and its relationship to individual characteristics.

Assessment of the components of sarcopenia and quality of life perceived of individuals on hemodialysis.

Objectives: to evaluate the prevalence of sarcopenia in individuals aged 50 years or older on hemodialysis; to verify the association between sarcopenia and sociodemographic, clinical, anthropometric factors, components of sarcopenia and quality of life (QoL); and to correlate the components of sarcopenia with QoL.

Methods: Participated 83 individuals on hemodialysis. Sarcopenia was established according to the current European consensus.

European Working Group on Sarcopenia in Older People 2010 (EWGSOP1) and 2019 (EWGSOP2) criteria or slowness: which is the best predictor of mortality risk in older adults?

Objectives: to analyse the accuracy of grip strength and gait speed in identifying mortality; to compare the association between mortality and sarcopenia defined by the EWGSOP1 and EWGSOP2 using the best cut-off found in the present study and those recommended in the literature and to test whether slowness is better than these two definitions to identify the risk of death in older adults.

Methods: a longitudinal study was conducted involving 6,182 individuals aged 60 or older who participated in the English Longitudinal Study of Ageing. Sarcopenia was defined based on the EWGSOP1 and EWGSOP2 using different cut-off for low muscle strength (LMS).

Assessment of the fat mass index in women recently diagnosed with gynecological tumors.

Objectives: to evaluate the nutritional status and body composition of women with gynecological tumors and evaluate the fat mass index (FMI) as a complementary indicator for addressing the nutrition status. Methods: a cross-sectional study with women recently diagnosed with gynecological tumors. Nutritional status was assessed using conventional anthropometry and the Patient-Generated Subjective Global Assessment.

The Role of Sarcopenic Obesity in Cancer and Cardiovascular Disease: A Synthesis of the Evidence on Pathophysiological Aspects and Clinical Implications.

Obesity is globally a serious public health concern and is associated with a high risk of cardiovascular disease (CVD) and various types of cancers. It is important to evaluate various types of obesity, such as visceral and sarcopenic obesity. The evidence on the associated risk of CVD, cancer and sarcopenic obesity, including pathophysiological aspects, occurrence, clinical implications and survival, needs further investigation.

Association of adductor pollicis muscle thickness and handgrip strength with nutritional status in hospitalized individuals.

Background: malnutrition is common in hospitalized patients and early diagnosis can contribute to better clinical and nutritional outcomes. Adductor pollicis muscle thickness (APMT) and handgrip strength (HGS) have been used to identify reductions in strength and muscle mass, associated or not with conventional methods. Objective: we aimed to correlate APMT and HGS with conventional anthropometric variables in hospitalized patients, and assess their relationship with nutritional status as evaluated by the Patient-Generated Subjective Global Assessment (PG-SGA) method.

Malnutrition and nutrition impact symptoms (NIS) in surgical patients with cancer.

Background And Aim: Nutrition impact symptoms (NIS) are common in cancer patients and the negative impacts on nutritional status indicate the need for research, diagnosis and nutritional intervention in order to reduce the risk of malnutrition. We aimed to verify the presence of malnutrition, the need for nutritional intervention, NIS and their influence on the nutritional status of surgical patients with cancer.

Methods: This cross-sectional study was carried out in a public tertiary hospital, from March 2017 to October 2019.

Gait speed and malnutrition in hospitalized patients and the quality of life of their caregivers.

Objective: To verify the age, nutritional status, and gait speed in hospitalized individuals, and their association with the quality of life of their caregivers.

Methods: Observational cross-sectional study with 54 patients and their respective caretakers in a university hospital in the Brazilian Midwest. The analyses were carried out using the SPSS software, with p < 0.

Spatial index relating urban environment to health lifestyle and obesity risk in men and women from different age groups.

The challenge in the search for relationships between urban space, physical mobility, and health status, is detecting indicators able to link the environment with healthy life habits. Therefore, the objective was to design an urban index for the identification of urban environment propensity for physical activity (PA) and to determine how it relates to lifestyle and anthropometric parametrization of obesity. Participants (N = 318-60.

Clinical, dietary and demographic characteristics interfering on quality of life of cancer patients.

Objective: To estimate the dietary intake of cancer patients and its relation with clinical and demographic characteristics, and to assess the contribution of dietary intake, appetite/symptoms and clinical and demographic characteristics to their quality of life.

Methods: The consumption of energy and macronutrients of patients was estimated. The relation between dietary intake and clinical and demographic characteristics was evaluated by analysis of variance.

Cross-cultural psychometric assessment of an appetite questionnaire for patients with cancer.

Objective: To evaluate the psychometric properties, along with cross-cultural invariance analysis, of the Cancer Appetite and Symptom Questionnaire (CASQ).

Method: Data from 555 United Kingdom (UK) cancer patients were used to evaluate the psychometric properties of the CASQ. Construct validity was assessed through factorial and convergent validity.

European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30: factorial models to Brazilian cancer patients.

Objective To evaluate the psychometric properties of the seven theoretical models proposed in the literature for European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), when applied to a sample of Brazilian cancer patients. Methods Content and construct validity (factorial, convergent, discriminant) were estimated. Confirmatory factor analysis was performed.

Cancer Appetite and Symptom Questionnaire (CASQ) for Brazilian Patients: Cross-Cultural Adaptation and Validation Study.

Background: Appetite and symptoms, conditions generally reported by the patients with cancer, are somewhat challenging for professionals to measure directly in clinical routine (latent conditions). Therefore, specific instruments are required for this purpose. This study aimed to perform a cultural adaptation of the Cancer Appetite and Symptom Questionnaire (CASQ), into Portuguese and evaluate its psychometric properties on a sample of Brazilian cancer patients.

Psychometric characteristics of the Functional Assessment of Cancer Therapy-General when applied to Brazilian cancer patients: a cross-cultural adaptation and validation.

Background: The psychometric properties of an instrument should be evaluated routinely when using different samples. This study evaluated the psychometric properties of the Functional Assessment of Cancer Therapy-General (FACT-G) when applied to a sample of Brazilian cancer patients.

Methods: The face, content, and construct (factorial, convergent, and discriminant) validities of the FACT-G were estimated.
