Many hormones fluctuate during the aging process. It has been suggested that gonadotropins, which increase with age, contribute to the occurrence of many diseases and syndromes in older life, such as cardiovascular diseases, obesity, frailty syndrome and osteoporosis. This study aims to assess the relationship between circulating gonadotropins and other hormones potentially contributing to age-related functional decline and sarcopenia indicators in 39 male and 61 female community-dwelling seniors, mean age 80 years. According to the definition developed by the second European Working Group on Sarcopenia in Older People (EWGSOP2), the following indicators of the sarcopenia were assessed: bioimpedance-measured body composition, gait speed, handgrip strength, timed up and go test (TUG), chair stand test, Short Physical Performance Battery (SPPB). Blood levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, testosterone, dehydroepiandrosterone sulphate (DHEAS) and cortisol were also measured. In the men, FSH and partially LH correlated positively with muscle mass percentage, gait speed, handgrip strength and SPPB, and negatively with percent body fat. Additionally, testosterone and DHEAS correlated negatively with the percentage of fat mass in men. Whereas in the women, FSH and LH were mainly negatively associated with body mass and adipose tissue measures. Cortisol did not show any relationship with the examined indicators. The study shows that the indicators of sarcopenia are strongly associated with levels of gonadotropins, sex hormones and DHEAS, especially in older men. The obtained results, after being confirmed in a larger group, may modify prevention and treatment strategies of sarcopenia.
Objectives: The aim of the present study was to examine and compare the relationship between nutritional status, physical activity (PA) level, concomitant chronic diseases, and quality of life (QoL) in community-dwelling (CD) older people and nursing home (NH) residents. Material and Methods: One hundred NH residents aged 60 years and above and one hundred sex- and age-matched CD older adults were examined. The QoL was examined with the EuroQol-5D questionnaire. Nutritional status was assessed with the Mini Nutritional Assessment questionnaire (MNA), anthropometric measures, and bioimpedance analysis (BIA). The 7-Day Recall Questionnaire and the Stanford Usual Activity Questionnaire were performed to evaluate the PA energy expenditure level (PA-EE) and the health-related behaviours (PA-HRB), respectively. Results: CD subjects presented a significantly higher self-assessment in the VAS scale in comparison with NH residents (CD: 65.3 ± 19.4 vs. NH 58.2 ± 21.4; p < 0.05), but there were no differences within the five dimensions of QoL. In NH patients, the VAS scale was not correlated with any of the variables evaluating the nutritional status and body composition, while in the CD group correlated positively with MNA (rS = 0.36; p < 0.001), % of FFM (rS = 0.22; p< 0.05), body density (rS = 0.22; p < 0.05) and negatively with % of FM (rS = −0.22; p < 0.05). In an institutional environment, only concomitant diseases (mainly urinary incontinence) were found as independent determinants for QoL. In the community, independent determinants of QoL besides concomitant diseases (mainly ischaemic heart disease) were nutritional status or PA-HRB. Conclusions: Determinants of QoL are different depending on the living environment the older adults. Proper nutritional status and beneficial PA behaviours, are crucial for higher QoL of CD elderly, while for NH residents, the main determinants of QoL are chronic conditions.
Myostatin, its inhibitor follistatin, and growth/differentiation factor 11 (GDF11) have been proposed as factors that could potentially modify biological aging. The study aimed to test whether there is a relationship between these plasma circulating proteins and muscle strength, power and optimal shortening velocity (υopt) of older adults. The cross-sectional study included 56 women and 45 men aged 60 years and older. Every participant underwent examination which included anthropometric and bioimpedance analysis measurements, functional and cognitive performance tests, muscle strength of upper and lower extremities, muscle power testing with two different methods and blood analyses. Women had higher plasma levels of myostatin and GDF11 than men. Men had higher plasma level of follistatin than women. In women, plasma level of myostatin was negatively correlated with left handgrip strength and υopt. Follistatin was negatively correlated with maximum power output (Pmax), power relative to kg of body mass (Pmax∙kg− 1) (friction-loaded cycle ergometer) and power at 70% of the 1-repetition maximum (1RM) strength value (P70%) of leg press (Keiser pneumatic resistance training equipment), and positively correlated with the Timed Up & Go (TUG) test. GDF11 was negatively correlated with body mass, body mass index, waist circumference, fat mass and the percentage of body fat. In men, there were no significant correlations observed between circulating plasma proteins and muscle function measures. The circulating plasma myostatin and follistatin are negatively associated with muscle function in older women. There is stronger relationship between these proteins and muscle power than muscle strength. GDF11 has a higher association with the body mass and composition than muscle function in older women.
Zachowania dobrostanu i samodzielności przez osoby starsze wynika z wdrażania zasad „dobrego starzenia się” opartego na aktywności i uczestnictwie w życiu zawodowym i społecznym oraz promocji zdrowego stylu życia. Coraz większe znaczenie przypisuje się rozpowszechnieniu zespołu słabości wśród pacjentów w wieku podeszłym. Pacjenci ci charakteryzują się zwiększoną wrażliwością na bodźce, upośledzoną zdolnością do radzenia sobie z wewnętrznymi i środowiskowymi czynnikami stresogennymi, a także posiadają ograniczoną zdolność do utrzymania stanu fizjologicznej i psychospołecznej homeostazy W takich przypadkach konieczne jest wsparcie pacjentów opieką zintegrowaną polegającą na wsparciu środowiska oraz najnowszej technologii. Zapewnienie mieszkańcom województwa dolnośląskiego wysokiej jakości życia, dopasowanie usług społecznych do potrzeb mieszkańców oraz sama integracja społeczna są zgodne ze Strategia Integracji Społecznej na Dolnym Śląsku. Dlatego też, na Dolnym Śląsku wsparcie takich pacjentów technologią, zostało zapoczątkowane pilotażem projektu CareWell i WRP®. Zastosowanie nowych technologii wymaga kampanii społecznej, informacji w mediach i wzbudzenia społecznego zaciekawienia, wręcz mody na ich stosowanie. Pozwoli to na doskonalenie nowych usług, obniżenie kosztów i poprawę bezpieczeństwa ludzi. W miejsce kosztownej opieki specjalistycznej pacjenci w wieku podeszłym uzyskują opiekę indywidualizowaną, lokowaną w środowisku, mniej kosztowną lecz bardziej intensywną. Projekt FOCUS zajmuje się zmniejszeniem obciążenia zespołem słabości w populacji osób w wieku podeszłym w Europie z uwzględnieniem wzmocnienia wsparcia środowiskowego. Celem projektu SUNFRAIL jest poprawa identyfikacji, zapobiegania i zarządzanie zespołem słabości oraz opieką nad wielochorobowością wśród osób po 65 roku życia mieszkających w społeczności lokalnej przez regionalne ośrodki i instytucje krajów UE.
The study analyzes the relationship between nutritional status and depression symptoms severity in the older population. A total of 1975 older outpatients (1457 women and 518 men, median age 75) were included in the study. Depression symptoms severity was assessed using the Geriatric Depression Scale (GDS). Participants were divided into two subgroups according to GDS score. Group A: 0–5 points—without depression symptoms (1237, W:898, M:339), and group B: 6–15 points—with depression symptoms (738, W:559, M:179). The nutritional status of the patients was assessed with Mini Nutritional Assessment (MNA) and basic anthropometric variables (waist, hips, calf circumferences, body mass index (BMI), waist to hip ratio (WHR), and waist to height ratio (WHtR)). Education years and chronic diseases were also noted. Women with higher depression symptoms severity had significantly lower MNA scores [A: 26.5 (24–28) (median (25%−75% quartiles)) vs. B:23 (20.5–26)], shorter education time [A:12 (8–16) vs. B:7 (7–12)], smaller calf circumference [A:36 (33–38) vs. B: 34 (32–37)], and higher WHtR score [A:57.4 (52.3–62.9) vs. B:58.8 (52.1–65.6)]. Men with depression symptoms had lower MNA scores [A:26.5 (24.5–28) vs. B:24 (20.5–26.5)], shorter education [A:12 (9.5–16), B:10 (7–12)], and smaller calf circumference [A:37 (34–39), B:36 (33–38)]. In the model of stepwise multiple regression including age, years of education, anthropometric variables, MNA and concomitant diseases nutritional assessment, and education years were the only independent variables predicting severity of depression symptoms both in women and men. Additionally, in the female group, odds were higher with higher WHtR. Results obtained in the study indicate a strong relationship between proper nutritional status and education level with depression symptoms severity in older women and men.
Plasma osteopontin (pOPN) is a promising aging-related biomarker among individuals with and without kidney disease. The interaction between sex, pOPN levels, and global and cardiorenal outcomes among older individuals was not previously evaluated.
Background/Objectives: Hypomagnesemia and hypocalcemia are common conditions among older adults that may contribute to cognitive decline. However, most of the existing research has focused primarily on dietary intake rather than the actual serum levels of these nutrients or examined them separately. This study aims to investigate the relationship between hypomagnesemia, hypocalcemia, and the concurrent presence of both deficiencies in relation to cognitive performance among seniors. Methods: A total of 1220 hospitalized patients aged 60 and older were included in the analysis. The participants were categorized into four groups: those with normal serum levels of magnesium and calcium, those with hypomagnesemia, those with hypocalcemia, and those with both serum magnesium and calcium deficiencies. To evaluate the potential influence of age, sex, common comorbidities, and disturbances in magnesium and calcium levels on cognitive performance, two general linear models were employed, using the Mini-Mental State Examination (MMSE) and Clock-Drawing Test (CDT) as dependent variables. Results: After adjusting for age, sex, body mass index, and comorbidities, the mean values for the MMSE and CDT were 23.33 (95%CI: 22.89–23.79) and 5.56 (95%CI: 5.29–5.83) for the group with normomagnesemia and normocalcemia, 22.59 (95%CI: 21.94–23.24) and 5.16 (95%CI: 4.77–5.54) for the group with hypomagnesemia, 19.53 (95%CI: 18.36–20.70) and 4.52 (95%CI: 3.83–5.21) for the group with hypocalcemia, and 21.14 (95%CI 19.99–22.29) and 4.28 (95%CI 3.61–4.95) for the group with both hypomagnesemia and hypocalcemia, respectively. Magnesium and calcium deficiencies contributed to MMSE and CDT variance in the general linear models. Conclusions: Our findings indicate that in addition to age, body mass index, and chronic heart failure, both hypomagnesemia and hypocalcemia are associated with reduced cognitive performance.
