Background/Objectives: Malnutrition in older adults is both preventable and treatable, yet its detection and etiology remain complex. Therefore, the aim of this study was to evaluate the prevalence of malnutrition and various factors involved in the etiology of malnutrition in community-dwelling individuals aged 65 years and older. Methods: This cross-sectional study was conducted with community-dwelling individuals aged 65 years and older in a health center in Ağrı, Türkiye. The nutritional status of older adults was measured using the Mini Nutritional Assessment (MNA). Data were collected through face-to-face interviews and a series of validated instruments, including the Standardized Mini Mental Examination (MMSE), body composition measurements (BIA), dietary intake records, and physical performance tests such as hand grip strength, chair stand, and Timed ‘Up & Go’ (TUG) Test. Statistical analyses included chi-square and Mann-Whitney U tests for group comparisons and logistic regression to investigate independent factors associated with risk of malnutrition. Results: A total of 182 participants were included in the study. The mean age of the participants was 72.1 ± 6.0 years. Of the participants, 59.3% were male. 1.6% of the participants were malnourished, and 25.3% were at risk of malnutrition. Perceived health status compared to peers (OR: 1.734, 95% CI: 1.256–2.392, p = 0.001), lower appetite status (OR: 1.942, 95% CI: 1.459–2.585, p < 0.001) and lower waist circumference (OR: 1.089, 95% CI: 1.040–1.140, p < 0.001) were independent predictors of malnutrition risk. Conclusions: The risk of malnutrition was higher among individuals with lower appetite, poorer self-perceived health status compared to peers, and smaller waist circumference. Reduced physical function and strength were also associated with an increased risk of malnutrition. Full article

Background and Objectives: Adverse clinical outcomes are associated with malnutrition and frailty, which are highly prevalent among hospitalized older patients. This study aimed to evaluate their predictive value for the duration of hospitalization, short-term survival, and rehospitalization of patients admitted to internal medicine wards. Materials and Methods: This prospective cohort study included 134 acutely ill patients aged ≥50 years who were hospitalized in an internal medicine department and evaluated within the first 48 h of admission. Nutritional status was evaluated using the Mini nutritional assessment–short form (MNA-SF), Nutritional Risk Screening 2002 (NRS-2002), and Global Leadership Initiative on Malnutrition (GLIM) criteria. Frailty was evaluated using the FRAIL scale and Clinical Frailty Scale (CFS). The primary outcomes were prolonged hospitalization (>10 days), mortality, and rehospitalization at 3 and 6 months post-discharge. Results: According to MNA-SF, 33.6% of patients were malnourished; 44% had nutritional risk per NRS-2002, and 44.8% were malnourished per GLIM. Frailty prevalence was 53.7% (FRAIL) and 59% (CFS). Malnutrition defined by all three scales (MNA-SF, NRS-2002, GLIM) was significantly associated with prolonged hospitalization (p = 0.043, 0.014, and 0.023, respectively), increased rehospitalization at both 3 months (p < 0.001) and 6 months (p < 0.001). Mortality was also significantly higher among malnourished patients. Higher CFS scores and low handgrip strength were additional predictors of adverse outcomes (p < 0.05). In multivariable analysis, GLIM-defined malnutrition and CFS remained independent predictors of rehospitalization and mortality. Conclusions: Frailty and malnutrition are highly prevalent and independently associated with prolonged hospital stay, short-term rehospitalization and mortality. Routine screening at admission may facilitate early identification and guide timely interventions to improve patient outcomes. These findings might guide hospital protocols in aging health systems and support the development of standardized geriatric care pathways. Full article

Hip fractures in elderly patients pose significant clinical challenges, confronting us with high morbidity and mortality rates. A comprehensive geriatric assessment plays an important role in determining prognosis as well as the indication for surgery. Aim: In this study, we aim to (1) assess frailty-based functional status in seniors with hip fractures, (2) evaluate geriatric assessment’s predictive value for postoperative recovery, and (3) analyze 1-year postoperative survival. Material and Methods: This prospective study included 60 senior patients admitted for hip fracture in the Orthopedics Department. Patients were examined using geriatric assessment instruments Mini Mental State Examination (MMSE), Geriatric Depression Scale (GDS), Mini Nutritional Assessment (MNA), and Frailty Groningen Indicator (GFI). We recorded the sex, marital status, number of comorbidities, and number of recommended drugs. Results: In total, 65% of patients were frail pre-surgery; the proportion increased post-surgery to 86.7%; (p = 0.005). Age greater than 80 years and unmarried marital status were associated with higher frailty risk (p = 0.04; p = 0.03). Preoperatively, important predictors of frailty were mild–moderate cognitive impairment (p = 0.017), mild–moderate depression (p = 0.01), and malnutrition (p = 0.04). Postoperatively, only mild–moderate cognitive impairment (p = 0.04) and mild–moderate depression (p = 0.01) proved to be important predictors of frailty. According to the ROC curve, good predictors of postoperative frailty were shown to be preoperative frailty and the degree of polypharmacy and comorbidity. Of all parameters predictive of postoperative frailty, only the number of medications reached statistical significance (p < 0.038). The study identified a 1-year all-cause mortality rate of 42.6% in elderly patients who underwent hip fracture surgery, with a significant association between mortality and preoperative MMSE, GDS, and MNA scores. Conclusions: Complex geriatric assessment of senior patients with hip fracture can stratify postoperative risk and predict 1-year mortality and postoperative functional recovery. Key predictors include cognitive status, depression, malnutrition, and comorbidities. Multidisciplinary care and standardized evaluation are essential for improving outcomes. Full article

Background/Objectives: Frailty is a key determinant of outcomes in older adults with heart failure (HF). The free triiodothyronine/free thyroxine (FT₃/FT₄) ratio has emerged as a promising frailty biomarker that reflects metabolic and systemic resilience. This study investigates its association with frailty, nutrition, muscle strength, inflammation, and one-year mortality in very old patients with HF. Methods: In this longitudinal, single-center study, we enrolled 193 older outpatients (mean age, 86.5 ± 6.1 years; 56% women) recently discharged after acute HF. All patients underwent physical examination, blood testing, and comprehensive geriatric assessment, including handgrip strength (HGS). Participants were stratified by FT₃/FT₄ ratio (<1.7 vs. ≥1.7). Associations with the Clinical Frailty Scale (CFS) were examined using multivariable linear regression. Spearman’s correlations assessed relationships with inflammatory and nutritional biomarkers. Cox regression evaluated the association with all-cause mortality. Results: Patients with a low FT₃/FT₄ ratio (31.1%) exhibited greater frailty (CFS: median [IQR], 6 [2] vs. 4 [3]; p = 0.020), poorer nutritional status (Mini Nutritional Assessment: 10 [4] vs. 12 [3]; p = 0.008), and lower HGS (mean ± SD, 16.8 ± 3.7 kg vs. 20.3 ± 4.8 kg; p = 0.002). An inverse association was identified between the FT₃/FT₄ ratio and frailty (adjusted β = −0.09; p = 0.019). Individuals with low FT₃/FT₄ also showed elevated inflammatory markers and had more than double the one-year mortality rate compared to those with higher ratios [HR 2.32 (95% CI, 1.24–4.34; p = 0.007)]. Conclusions: In very old adults recently hospitalized for HF, a lower FT₃/FT₄ ratio was associated with frailty, malnutrition, inflammation, and increased mortality, supporting its potential role as a marker of biological vulnerability.

Objectives: This study aimed to evaluate the association between nutritional status and oral health-related quality of life (OHRQoL) in older adults from population-based studies of two cities in southern Brazil. Methods: A total of 569 community-dwelling individuals aged 60 years and older were included. Sociodemographic, dental, and behavioral data were collected. Nutritional status was evaluated using the Mini Nutritional Assessment (MNA). OHRQoL, the primary outcome, was measured using the Oral Health Impact Profile-14 (OHIP-14) questionnaire. Poisson regression with robust variance was applied in crude and adjusted analyses to evaluate the impact of nutritional status on OHIP-14 outcomes. Results: The prevalence of risk of malnutrition was 31.6%, while the mean OHIP-14 was 4.86 ± 7.55. Individuals with malnutrition risk (7.44 ± 9.95) showed overall OHIP-14 scores significantly higher than those with normal nutrition (3.65 ± 5.76) (p < 0.001). A similar trend in results was detected in all domains of OHIP-14 (p < 0.05). In the adjusted analysis, individuals at risk of malnutrition had a 66% higher prevalence ratio (PR) (95% confidence interval [95% CI]: 1.23–2.23) of having poorer OHRQoL. Associations were also observed for the severity (PR: 1.69; 95% CI: 1.31–2.19) and extent (PR: 2.33; 95% CI: 1.55–3.49) of OHIP-14. Conclusions: In conclusion, poorer nutritional status is significantly associated with a higher impact on OHRQoL in older adults. Full article

Background: Frailty is common in colorectal cancer (CRC) patients and is associated with poor prognosis and increased mortality. Anti-inflammatory dietary education is a promising and cost-effective strategy for frailty improvement. Methods: A prospective, assessor-blinded, two-arm randomized controlled trial was conducted to assess the effects of a 12-week dietary inflammatory index (DII)-based anti-inflammatory dietary education program on frailty in frail CRC patients. Participants in the intervention group received a DII-based anti-inflammatory dietary education, while the control group received a routine health education. Outcome measurements included the Fried frailty phenotype (FP), DII, plasma inflammatory biomarkers, body mass index (BMI), nutritional status, and quality of life (QoL), which were all assessed at baseline and post-intervention. Results: A total of 86.4% (57/66) of participants completed the follow-up. No statistically significant baseline differences were observed between groups. After the intervention, the intervention group showed significant improvements in DII (p = 0.029), BMI (p = 0.012), mini nutritional assessment (MNA) scores (p = 0.027), and QoL (p = 0.014) compared with the control group. Within-group comparisons revealed significant decreases in frailty status (p = 0.031), DII (p = 0.008), and interleukin (IL)-6 (p = 0.003), and significant increases in IL-10 (p = 0.021), MNA scores (p = 0.010), and QoL (p < 0.001) in the intervention group, with no significant changes in the control group. Conclusions: DII-based anti-inflammatory dietary education can improve the frailty, nutritional status, and QoL of frail CRC patients by modulating systemic inflammation. Given its acceptability and utility, this strategy may be incorporated into routine cancer health education. Full article

Background/Objectives: Bariatric surgery improves weight and metabolic health in individuals with severe obesity; however, challenges like gut dysbiosis and nutrient deficiencies persist postoperatively. Probiotic supplementation may enhance recovery by modulating gut microbiota. This updated meta-analysis aimed to assess the effects of probiotics/synbiotics on metabolic, anthropometric, and nutritional outcomes after bariatric surgery. Methods: A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted using PubMed, SCOPUS, Web of Science, and CENTRAL through December 2024. Studies comparing probiotics/synbiotics (which contain both probiotics and prebiotics) versus a placebo in adults post-bariatric surgery were included. Meta-analyses were conducted, with subgroup analyses by surgery type, the timing of the intervention, and probiotic formulation (PROSPERO ID: CRD420251019199). Results: Thirteen RCTs involving 809 patients were included in the analysis. Probiotic use significantly reduced BMI (MD = 0.67, 95% CI: 0.33 to 1.00), HbA1c (MD = −0.19%, 95% CI: −0.36 to −0.01), triglycerides (MD = −16.56 mg/dL), and AST levels (MD = −3.68 U/L), while increasing ALP (MD = 8.12 U/L) and vitamin D (MD = 13.68 pg/mL). Ferritin levels were significantly lower (MD = −18.89 µg/L) in the probiotic group. A subgroup analysis showed enhanced benefits in patients undergoing mini-gastric bypass, with perioperative or synbiotic interventions specifically improving triglycerides, total cholesterol, and HbA1c. Conclusions: Probiotics may offer modest but significant improvements in BMI, glycemic control, lipid profile, liver enzymes, and vitamin D levels after bariatric surgery. These findings support the potential role of probiotics/synbiotics as an adjunct therapy, though further large-scale trials are warranted to confirm long-term benefits. Full article

Background/Objectives: Loop diuretics are among the most commonly used drugs in patients with heart failure with reduced ejection fraction (HFrEF). Higher doses of these diuretics are associated with poorer clinical status and may contribute to malnutrition. The study aims to assess the relationship between the use of high-dose loop diuretics and nutritional status in patients with HFrEF. Methods: The study included 353 hospitalized patients with HFrEF. Nutritional status was assessed using the Mini Nutritional Assessment (MNA), the Geriatric Nutritional Index (GNRI), and the CONtrolling NUTritional status (CONUT). Patients were divided into three groups according to the daily dose of loop diuretics (defined as furosemide equivalent = 1 × furosemide dose and 2 × torsemide dose): low dose (LD), 40 mg/day or no treatment; medium dose (MD), 41–160 mg/day; or high dose (HD), >160 mg/day. Results: Of the evaluated patients, the mean MNA score was 23.31 ± 2.93 points, and 49.8% were at risk of malnutrition or malnourished. According to the MNA, patients in HD and MD groups had worse nutritional status than the LD group, similarly according to the GNRI. For CONUT, the differences were significant between all groups: nutritional status was the worst in the HD group, intermediate in the MD group, and the best in the LD group. Conclusions: The intake of loop diuretics, especially in high doses, correlates with an elevated risk of malnutrition in patients with HFrEF independently of sex, age, NYHA class, and left ventricular ejection fraction.

Background: This study aimed to evaluate the impact of physical activity levels on selected biochemical markers (glucose, insulin, cholesterol, triglycerides, interleukin-6 [IL-6]), brain-derived neurotrophic factor (BDNF), cognitive functions, and additional macronutrient intake in postmenopausal women. Method: A total of 72 generally healthy women aged 55–73 from western Poland participated in the study. Physical activity levels were assessed using the International Physical Activity Questionnaire (IPAQ), resulting in two distinct groups: 56 women in the lower activity level group and 16 in the higher activity level group. We calculated body mass index (BMI), measured body composition and blood pressure, and conducted cognitive assessments, including the Mini-Mental State Examination (MMSE), motor and psychomotor skills tests, the Clock Drawing Test, and the Geriatric Depression Scale (GDS). Nutritional intake was evaluated using a detailed 3-day food record to analyze macronutrient consumption and total caloric intake. Results: A statistically significant difference in total blood cholesterol levels (p = 0.0277) was observed between the two groups, with the higher physical activity group showing elevated cholesterol levels. Although no other biochemical markers showed statistically significant differences, variations in BDNF, glucose, triglycerides, IL-6, and insulin levels were noted between groups. Moreover, correlations between these markers and cognitive performance, like motor and psychomotor speeds, varied depending on physical activity level. The analyzed dietary pattern of the studied group shows slight deviations from current nutritional recommendations. Conclusions: The findings suggest that physical activity level may influence certain biochemical markers and cognitive functions in postmenopausal women. While these results highlight the potential benefits of physical activity, further research is needed to clarify underlying mechanisms and to validate physical activity as an effective strategy for improving postmenopausal health.

Background: There is limited knowledge about nutritional intake and energy needs during the post-intensive care unit (ICU) period and their relationship with clinical outcomes and physical recovery. Aims and Methods: Thus, this observational multicenter study (Azienda Ospedaliero-Universitaria “Santa Maria”, Terni and “Madonna del Soccorso” General hospital, San Benedetto del Tronto, Italy) aimed, firstly, to measure energy expenditure via indirect calorimetry (IC) (Q-NRG+^® Metabolic Monitor, Cosmed, Rome, Italy), derived respiratory quotient (R/Q1) and, malnutrition risk via Mini Nutritional Assessment (MNA) test and body composition through bioimpedance vector analysis (BIVA-Akern, Pontassieve, Italy); secondly, to assess their effect on energy needs, body composition and physical rehabilitation steps in critically ill adults after ICU discharge. The provision of nutrients (PIS test) was also recorded. Oral nutritional supplementation was used to reach the optimal nutritional intake. All patients followed a standardized rehabilitation program. Results: A total of 43 patients were enrolled from January 2024 until February 2025 at the beginning of their post-ICU period. The mean age was 65.7 ± 1.0 years, the mean BMI was 20.73 ± 0.8 kg/m² at the recovery ward, and 60.4% (n = 26) were male. The mean admission period was 19.5 ± 1.7 days. The resting energy expenditure (mREE) was 1591 ± 71.2 at the admission and 1.856 ± 62.7 kcal/kg/d at the discharge (p < 0.05). The median phase angle value was 4.33 ± 0.15 at the admission and 5.05 ± 0.17° at the discharge (p < 0.05); R/Q1 at the admission was 0.7 ± 0.1 and 1.086± 0.11 at the discharge (p < 0.05). Improved energy expenditure significantly correlated with R/Q1 and phase angle (r = 0.81 and r = 0.72, respectively). Interestingly, there was no significant correlation between improved metabolism and improved PIS test scores (r = 0.18). Improved metabolism and nutritional status showed a tendency to correlate with shorter post-ICU courses and earlier physical recovery, without reaching statistical significance. Conclusions: Measurement of energy expenditure and caloric intake, along with the assessment of body composition is feasible and provides an objective tool to guide and possibly enhance the functional recovery in patients during the post-ICU period.

Background: Oral frailty is a state between normal oral function and oral hypofunction. Oral frailty progresses to oral hypofunction and dysphagia, which leads to malnutrition, and then to physical frailty and sarcopenia. Oral frailty is reported to be associated with physical frailty and malnutrition in hemodialysis patients, but there have been no reports on peritoneal dialysis (PD) patients. Methods: This prospective cohort study investigated the associations of oral frailty with physical frailty, sarcopenia, and malnutrition in patients on PD. Patients were divided into an oral frailty group and a non-oral frailty group according to the Oral Frailty Index-8. Patients were assessed for physical frailty, sarcopenia, and malnutrition at baseline and 1 year later, and changes in each measure were compared between the two groups. Physical frailty was assessed using the Revised Japanese version of the Cardiovascular Health Study Criteria (Revised J-CHS) and the FRAIL scale. Sarcopenia was assessed using the diagnostic criteria reported by the Asian Working Group for Sarcopenia in 2019 (AWGS2019 criteria) and the Screening Tool for Sarcopenia Combined with Calf Circumference (SARC-CalF), skeletal muscle index (SMI), calf circumference (CC), grip strength, and gait speed. Nutritional status was assessed with the Short-Form Mini-Nutritional Assessment (MNA-SF), the Malnutrition Universal Screening Tool (MUST), the Global Leadership Initiative on Malnutrition (GLIM) criteria, weight, and body mass index (BMI). Results: Of the 58 eligible patients, 51 completed the study. The oral frailty group was significantly older and had slower gait speed, fewer teeth, higher intact parathyroid hormone, higher C-reactive protein, higher frequency of cardiovascular disease, and lower employment at baseline. The oral frailty group had significantly worse physical frailty (Revised J-CHS, p = 0.047; FRAIL scale, p = 0.012), sarcopenia (SMI, p = 0.018; CC, p = 0.002), and nutritional status (MNA-SF, p = 0.029; MUST, p = 0.005; GLIM criteria, p = 0.022; weight, p < 0.001; BMI, p < 0.001). However, there were no significant differences in the worsening of sarcopenia (AWGS2019 criteria, SARC-CalF, grip strength, and gait speed). Conclusions: Oral frailty in patients on PD was associated with the development and progression of physical frailty and malnutrition, and may be associated with the development and progression of sarcopenia.

Background: The global population is rapidly aging, and an epidemic increase in chronic kidney disease (CKD) has been reported. As the presence of malnutrition in elderly CKD patients can pose serious health problems, the aim of our study was to identify, using different assessment tools, the relationship between nutrition with kidney function and albuminuria in elderly patients. Methods: The study included 793 hospitalized patients aged 65 years and older. A comprehensive assessment of nutritional status and renal involvement was performed, and the relationship between malnutrition and kidney issues was tested. Results: CKD was highly prevalent in our geriatric population, with 39.84% having CKD G3a–5. Malnutrition, determined according to the Mini Nutritional Assessment (MNA) score, was identified in 34.6% of patients. With an increase in albuminuria, we observed worse nutrition indicators: low serum albumin; lower body fat (p = 0.002) and visceral fat (p = 0.001), assessed via bioimpedance; and lower MNA (p = 0.04) and geriatric nutritional risk index (GNRI) (p = 0.002) scores. Elderly patients with CKD G3a–5 had lower HDL-cholesterol (p < 0.001), higher triglycerides (p < 0.001), lower albumin (p = 0.011), and a lower MNA score (p = 0.001). Conclusions: Malnutrition was found to be common and more severe with increased albuminuria and decreased eGFR. Our study sheds light on a novel relationship between malnutrition, albuminuria, and renal function in a geriatric population. Full article

Background: Assessing nutrition-related health risks in older individuals is often overlooked in clinical practice due to the lack of appropriate methods of evaluation. While anthropometric measurements and body composition analyses are mainly used, these tools are not standardized for the oldest old and fail to account for age-related changes. This underscores the need for improved assessment techniques that accurately capture the progressive and non-linear shifts in nutritional status throughout the aging process. Accordingly, the primary aim of our paper is to identify the most effective tools to use for evaluating nutritional status in the oldest population. Methods: To address this gap, we conducted a cross-sectional study, investigating the nutritional status of a cohort of Sicilian individuals aged between 65 and 111, using methods commonly applied to adult and older adult populations. These included the BIoimpedance Analysis (BIA), the Mini Nutritional Assessment (MNA) evaluation, and nutritional risk indices such as the COntrolling NUTritional Status (CONUT) score and Geriatric Nutritional Risk Index (GNRI). Results: Despite the oldest population being classified as “at risk” of malnutrition by the MNA or “cachetic” by BIA, our results indicated a “normal” or “low risk” of malnutrition when assessments were performed using tools (GNRI and CONUT) that were not reliant on body composition parameters. These findings align with clinical history assessments conducted during their recruitment. Conclusions: This pilot study highlights the need for future research aimed at developing standardized, multidimensional assessment models tailored to the heterogeneity of each age group, to improve risk stratification, clinical outcomes, and personalized nutritional care.

Background/Introduction: Undernutrition’s impact on healthcare utilisation across age groups and care settings remains underexplored, particularly in Asian contexts. This study investigated the dynamic association between nutritional status and healthcare utilisation among community-dwelling adults in Singapore and assessed whether age modified this relationship. Methods: The study sampled 1703 adults enrolled in the Population Health Index study. Nutritional status was assessed annually using the Mini Nutritional Assessment, and healthcare utilisation data—across primary care, specialist outpatient clinics (SOCs), emergency departments (EDs), day surgeries, and inpatient admissions—were extracted from administrative databases. Negative binomial regressions with interaction terms using longitudinal panel data were conducted to examine age-modified effects. Results: At baseline, 9.7% of participants were classified as undernourished, with a higher prevalence in older adults (15.0%). Key risk factors for undernutrition included female sex, unemployment, financial inadequacy, currently smoking, lack of formal education, and multimorbidity. Undernutrition was associated with increased ED visits (IRR 1.41, AME: 0.35) and inpatient admissions (IRR 1.52, AME: 0.42). Among older adults, undernutrition was associated with less primary and specialist care (IRR: 0.72 and 0.57), while younger undernourished adults had more SOC visits (AME: 0.46). Older undernourished adults had 0.46 more ED visits and 0.47 more inpatient admissions on average in one year, though these increases did not differ from younger adults (interaction p > 0.05). Conclusions: Undernutrition is associated with increased ED visits and inpatient admissions, especially in older adults. Integrating nutritional screening and targeted interventions into community and primary care may help reduce preventable hospitalisations in high-risk populations. Full article

Background/Objectives: Sarcopenia, characterized by the loss of muscle mass and strength, is prevalent in older persons and affects their quality of life. Nutritional intervention and physical activity play a key role in its prevention and treatment. This study aims to investigate the relationship between food consumption frequency as assessed through the Mini Nutritional Assessment (MNA) and probable sarcopenia, evaluated by grip strength, in Chilean older persons aged 65 or older. Methods: A correlational, cross-sectional study with a non-probabilistic sample of 155 older persons aged 65 or older was undertaken. Food consumption frequency was assessed using the MNA, and muscle strength was measured using a handgrip dynamometer. The authors analyzed the relationship between food consumption frequency, as assessed by the MNA, and the protein intake index with muscle strength. Results: Participants who consumed less than two servings of fruits and vegetables per day were 4.28 times more likely to have low muscle strength compared to those who consumed two or more servings per day (OR = 4.28; 95% CI: 1.59–11.45). No significant associations were found with the consumption of dairy products, legumes, meat, fish, poultry, or fluids. The protein intake index did not show a significant relationship with muscle strength. Conclusions: The results suggest that a diet rich in fruits and vegetables may have a protective effect on muscle strength in older persons. Promoting adequate intake of these foods could be critical in the prevention of sarcopenia in this population. Full article
