Associação entre rigidez arterial e alterações dos domínios da capacidade intrínseca: locomoção e cognição avaliada pela proposta da Organização Mundial da Saúde em pessoas idosas da atenção primária
(Faculdade Ciências Médicas de Minas Gerais, 2025-07-07) Sousa, Kamila Andrade de; Machado, Maria da Glória Rodrigues; Pereira, Leani Souza Máximo
Background: The World Health Organization (WHO) proposes, as a public health policy and strategy, the Integrated Care for Older People (ICOPE), based on the concepts of intrinsic capacity (IC) and functional ability in primary care. To date, no studies have been identified investigating the association between arterial stiffness (AS) and changes in the locomotion and cognition domains of IC in older adults. Objectives: To assess whether AS indices are associated with changes in the locomotion and cognition domains proposed by the WHO/IC in older adults in primary care. Methods: This was a cross-sectional study using baseline data from the ICOPE BRAZIL cohort. Older adults (≥60 years) registered in Primary Health Care Units (UBS) were included, except for those unable to travel to the UBS. Vascular, hemodynamic, and AS parameters were assessed by brachial artery oscillometry using the Mobil-O-Graph® (IEM, Stolberg, Germany). Locomotion was assessed using the 4-meter gait speed test (GS4) in meters per second (m/s), and cognition was evaluated using the Mini-Mental State Examination (MMSE). Bivariate regressions were conducted between GS4, MMSE, PWV, and sociodemographic variables using Pearson’s test for continuous variables and biserial correlation for continuous and categorical variables. Structural Equation Modeling via Path Analysis was used to assess the multivariate associations between the variables described above. Results: Ninety-five older adults participated in the study, with a mean age of 68.65 ± 6.44 years [67.00] and mean education of 7.05 ± 4.89 years [5.00]. In bivariate analyses, AS measured by PWV (r = -0.31; p = 0.003) was negatively correlated with cognition (MMSE). Significant correlations with cognition were also observed for age (r = -0.34; p < 0.001) and locomotion (GS4) (r = 0.29; p = 0.005). Locomotion was negatively correlated with body mass index (BMI) (r = -0.25; p = 0.014). Path Analysis showed that age and BMI were directly and significantly associated with PWV (βAge = 0.18, p < 0.001; βBMI = 0.03, p = 0.005; R² = 0.83). Regarding cognition, associations were found with age and PWV (βAge = -0.30, p = 0.045; βPWV = -1.07, p = 0.002; R² = 0.10). For locomotion, associations were observed with BMI, MMSE, and PWV (βBMI = -0.01, p = 0.017; βMMSE = 0.02, p = 0.027; βPWV = -0.06, p = 0.02; R² = 0.15). Conclusion: Associations were found between AS, measured by PWV, and IC (locomotion and cognition) in older adults in primary care. Increased age and BMI significantly impacted PWV, leading to impairments in locomotion and cognition. Early identification of AS changes using a non-invasive, examiner-independent tool in primary care may allow better clinical management and prevent worsening of cardiovascular diseases. Furthermore, it may help detect alterations in locomotion and cognition, thus complementing the WHO/IC/ICOPE framework.

Introduction: Chronic kidney disease is currently considered a health problem worldwide and protein-energy malnutrition in these patients is frequent and an important predictor of morbidity and mortality. Kidney transplantation can improve patient's quality of life and survival, but complications after the procedure are still significant and may be associated with the recipient's nutritional status. Little consideration is given to nutrition in the preparation phase and in kidney transplant surgery and, therefore, the prevalence of malnourished patients before and after transplantation and the influence of the nutritional status on results after the procedure are still underestimated. Objectives: To assess the impact of the nutritional status in recipients before kidney transplantation on renal function, clinical outcomes, graft survival and risk of death. Material and Methods: In this retrospective cohort study including 451 transplanted patients between 2008 and 2018, at University Hospital of The Faculty of Medical Sciences, an easy to use nutritional screening tool was developed for patients in preparation for kidney transplantation, based on anthropometric, laboratory and clinical data. For this, a risk score was elaborated with these data. The sum of all components of the score varies from 0 to 12 points. The patients were stratified into three groups, according to the final score: G1 (0 to 2 points) = low risk; G2 (2-4 points) = moderate risk and G3 (> 5 points) = high risk of malnutrition. Results: Stratifying the 451 patients based on the pre-transplant risk score, G1 was composed of 90, G2 of 292 and G3 of 69 patients. G1 patients maintained the lowest creatinine levels at the time of hospital discharge after transplantation, when compared to the other two groups (p = 0.012). Transplant recipients from G3 had a higher proportion of graft losses, with the mean graft survival time in months being 100.56 + 46.49 in G1, 94.64 + 54.34 in G2 and 77.76 +49.01 in G3 (p = 0.044). The Kaplan-Meier survival curve showed better survival for patients in G1, when compared to the other groups (p = 0.046). G3 patients had almost three times greater risk of graft loss (Hazard Ratio [HR] 2.94; 95% CI; 1.084-7.996). Sensitized patients and patients with delayed graft function had almost twice the risk (HR 1,904, 95% CI 1,168-3,105; HR 1,921, 95% CI 1,238-2,980) and patients with cellular rejection or humoral rejection had a 2.18 times greater risk (HR 2,180, 95% CI 1,251-3,798) of graft loss. Conclusion: Kidney transplant patients with a higher risk of malnutrition according to the pre transplant score were associated with worse outcomes and graft survival. The nutritional screening tool is easy to be used in clinical practice to evaluate the patient in preparation for kidney transplant.

(Faculdade Ciências Médicas de Minas Gerais, 2017-10-06) Oliveira Sobrinho, Ismael Gomes de; Almeida, Alessandra Maciel; Passos, Maria do Carmo Friche
Introduction Irritable Bowel Syndrome (IBS) is a functional intestinal disorder that affects about 11% of the world population and is really associated to psychological stress and psychiatric comorbidities. According to the medical literature the prevalence of IBS in psychiatric patients is significantly higher than in the general population, and the epidemiological data are analyzed together, once they bring significant impacts on quality of life and high direct and indirect costs. There are few studies that evaluate the prevalence of IBS in psychiatric patients, and there is no study in the Brazilian population. Objective: To investigate the prevalence of IBS in patients diagnosed with depression, generalized anxiety disorder and panic disorder in a psychiatry service. Materials and Methods: One hundred and eighty-seven patients, aged between 18 and 65 years of age, treated in a psychiatry clinical of Belo Horizonte/Brazil, agreed documentally to participate in the study. They first responded to a structured questionnaire containing demographic and health data and subsequently underwent a standardized questionnaire (MINI) to obtain their respective psychiatric diagnoses. After exclusion criteria, 113 of these patients were subjected to a specific questionnaire for diagnosis of IBS according to diagnostic criteria of Rome III. Results: Of the 113 patients, 70 (61.9%) were female and 43 (38.1%) male, 70 (61.9%) were 31 years of age or older. The married or in a stable union patients made up a total of 61 patients (54%), the same number found for patients who attended higher education (54%). Among the patients, 92 (81.4%) lived in the capital and 82(72.6%) reported having non-white complexion. The prevalence IBS according to the diagnostic criteria of Rome III was 40.7%, and the subtype diarrhea was the most common (20.4%), followed by the mixed subtype (12.4%) and finally the constipation subtype (8%). The prevalence in patients diagnosed with depression was 29.6%, with generalized anxiety disorder in 60%, and in those with panic disorder, 58.3%. Conclusion: The results of this Brazilian populational study are in agreement with previous studies performed in various regions of the world, that using similar parameters of evaluation show a higher prevalence of IBS in psychiatric patients than in the general population. The prevalence of IBS according to the Rome III criteria was 40.7% in this population with psychiatric diseases.
Correlação entre alcoolemia, álcool no ar expirado e exame clínico em um estudo clínico monitorado de ingestão de álcool
(Faculdade Ciências Médicas de Minas Gerais, 2017-12-06) Freitas, Rodrigo Gomes de; Wainstein, Alberto Julius Alves; Wainstein, Ana Paula Drummond Lage
Background: Policies that establish maximum blood alcohol concentrations (BACs) or breath alcohol concentration (BrACs) for drivers while driving can reduce traffic accidents by approximately 20%. In Brazil, the National Transit Council (CONTRAN) considers positive BAC and/or BrAC tests or signs of psychomotor capacity alterations as evaluated by a police authority to be an administrative infraction or even a crime. The observed clinical symptoms of alcohol intoxication based on a subject's appearance may not necessarily reflect the quantified BAC and/or BrAC. Methods: Brazilian health volunteers (n=15) drank ethanol (40% v/v) and, at scheduled times, the subjects underwent blood draws for BAC analysis, were tested for BrAC analysis, and underwent psychomotor alteration assessments performed by M (medical authority) and NM (non-medical authority). This study compared the clinical symptoms identified by M and a NM with BAC and BrAC measurements. Results: Concentration time profiles of the BACs and BrACs of the volunteer subjects were generated. The BAC values reached a peak at 60min and subsequently decreased with time. The average BrAC values decreased with time after ingestion. During the evaluations, M was able to identify a lack of static equilibrium until 240 min and a lack of dynamic equilibrium until 120 min. A lack of upper limb motor coordination was observed until 90 min, and a lack of coordination in the lower limbs was observed only during the first hour. Regarding the tests performed by NM, the signs related to the subjects' appearances were observed more frequently until 60 min. The other analyzed symptoms were not identified. Naturally, the signs reported by both M and NM disappeared with time. Conclusion: The evaluations of psychomotor changes performed by Brazilian M were superior to those performed by NM. However, independent of the examiner, at the alcohol concentrations reached in this study, the psychomotor alteration evaluations were ineffective compared with the BAC and BrAC results.
