This study examined the association of low handgrip strength (HGS) for falls in middle-aged adults and older adults every half-decade of life. This cross-sectional study was conducted using the public data from the first wave of the Brazilian Longitudinal Study of Aging (ELSI-Brazil). The participants were allocated into seven age groups 50–54, 55–59, 60–64, 65–69, 70–74, 75–79, and ≥ 80 years. Binary logistic regression analysis was performed to identify the odds ratio (OR) of low HGS to the falls regardless of confounding variables such as sex, balance, gait speed, and total number of health conditions. A total of 8,112 participants aged 50–105 years (median = 62.0 years): 3,490 males (median = 60.0 years) and 4,622 females (median = 63.0 years) attended the study. Altogether, 21.5% of participants experienced at least one fall. HGS gradually decreases over each half-decade of life. In addition, low HGS presented a significative OR (p < 0.05) for falls for age groups, until 80 s, even when considering confounding variables. Low HGS is associated with falls in middle-aged adults over their 50 s and remained a strong measure of falls across each subsequent half-decade of life, until 80 s.

Fractalkine, a unique chemokine of the CX3C subfamily, is involved in the pathogenesis of different types of cancer and also in non-immune mechanisms associated with psychiatric disorders. The aim of the present study was to investigate whether there is a correlation between anxiety, depression and fractalkine serum levels in colorectal cancer (CRC) patients in different stages of antitumor therapy. Four groups of patients undergoing treatment (n=20 per group) were evaluated: Patients with CRC who did not undergo surgical resection of the tumor; patients who underwent resection and who did not start adjuvant therapy; patients undergoing chemotherapy for similar to 3 months; and patients who had completed adjuvant chemotherapy regimen for similar to 6 months. The control group was composed of 20 healthy volunteers free of any psychiatric or immune system disease. Depression and anxiety were evaluated using the Hospital Anxiety and Depression Scale (HADS) and serum levels of fractalkine were measured by cytometric bead array. Clinically relevant levels of anxiety and/or depression were observed in all of the CRC patients at the different stages of antitumor therapy. Elevated serum levels of fractalkine were identified in the CRC patients in the pre-surgery (P<0.001) and pre-chemotherapy (P<0.001) groups, but reduced upon chemotherapy (P<0.05). Furthermore, a positive correlation was observed between fractalkine levels and the HADS scores in the CRC patients at different stages of antitumor therapy. These results demonstrate a link between fractalkine, depression and anxiety in CRC patients indicating that this chemokine is involved in the pathophysiology of these comorbidities. An improved understanding of the molecular mechanisms involved in these psychological disorders will allow the design of novel therapeutic strategies to assist in alleviating such symptoms in cancer patients. Therefore, fractalkine may present as a relevant biomarker for depression and anxiety in CRC patients.

Objective: to identify whether nursing professionals carry out hand hygiene, how they do it, and what resources are available for this practice during home visits. Method: cross-sectional study conducted in a public Home Care service. The World Health Organization instrument was used to observe the hand hygiene technique, the time of performance, and the product used. Results: a total of 940 hand hygiene opportunities taking place in 231 home visits were observed. Overall adherence was 14.4%, with the practice of hand hygiene being higher after contact with the patient (53.7%). Before aseptic procedures, after risk/exposure to body fluids, after contact with the patient’s environment, and before contact with the patient, adherence was 0.4%. Regarding the quality of the technique, in none of the 135 practices the recommended steps were followed. As for the structure available in the households, 35 (15.2%) had accessible sinks and none had liquid soap and alcohol-based formulation. Conclusion: adherence to hand hygiene by nursing professionals in home care was low, the technique was not performed, and households did not have resources for the practice.

The non-classical histocompatibility antigen G (HLA-G) is an immune checkpoint molecule that has been implicated in viral disorders. We evaluated the plasma soluble HLA-G (sHLA-G) in 239 individuals, arranged in COVID-19 patients (n = 189) followed up at home or in a hospital, and in healthy controls (n = 50). Increased levels of sHLA-G were observed in COVID-19 patients irrespective of the facility care, gender, age, and the presence of comorbidities. Compared with controls, the sHLA-G levels increased as far as disease severity progressed; however, the levels decreased in critically ill patients, suggesting an immune exhaustion phenomenon. Notably, sHLA-G exhibited a positive correlation with other mediators currently observed in the acute phase of the disease, including IL-6, IL-8 and IL-10. Although sHLA-G levels may be associated with an acute biomarker of COVID-19, the increased levels alone were not associated with disease severity or mortality due to COVID-19. Whether the SARS-CoV-2 per se or the innate/adaptive immune response against the virus is responsible for the increased levels of sHLA-G are questions that need to be further addressed.

This study examined the associations between age, adiposity, physical activity, sedentary behavior, and elevated blood pressure (BP) in 2901 Portuguese children and adolescents aged 2–18. BP, body mass index (BMI), waist-to-height ratio (WHtR), physical activity, and sedentary behavior were measured. Elevated BP was defined as a BP above the 90th percentile for age, sex, and height. Multivariable analyses assessed the prevalence ratios (PR) of elevated BP across age groups, BMI, WHtR, physical activity, and sedentary behavior. Results showed that older age, especially among middle schoolers, was associated with a 1.8 times higher risk of elevated BP than preschoolers. Participants with a higher BMI (overweight/obese) and a WHtR ≥ 0.50 had a 1.49- and 1.4-times higher risk of elevated BP, respectively. Those who did not meet the recommended 60 min of moderate-to-vigorous physical activity (MVPA) per day showed a 1.63 times higher risk of elevated BP, whereas the association between sedentary behavior and BP was not significant after adjustment. These findings highlight age, higher BMI, central obesity, and insufficient physical activity as key factors associated with elevated BP, underscoring the need for early monitoring and intervention to prevent hypertension in this population.
