RESUMEN

Objective: It has recently been highlighted how a short healthy life-style program (LSP) can improve the functional outcomes of older people admitted to a Long-Term Care (LTC) facility. Although it is known that life-style medicine-based interventions can exert anti-aging effects through the modulation of oxidative stress and mitochondrial function, the mechanisms underlying the aforementioned effects have not been clarified, yet. For this reason, in this study, the outcomes were focused on the investigation of the possible mechanisms underlying the benefits of a short LSP in older people. This was achieved by examining circulating markers of oxidative stress and immunosenescence, such as Tymosin ß (Tß4), before and after LSP and the effects of plasma of older people undergone or not LSP on endothelial cells. Methods: Fifty-four older people were divided into two groups (n = 27 each): subjects undergoing LSP and subjects not undergoing LSP (control). The LSP consisted of a combination of caloric restriction, physical activity, and psychological intervention and lasted 3 months. Plasma samples were taken before (T0) and after LSP (T1) and were used to measure thiobarbituric acid reactive substances (TBARS), 8-hydroxy-2-deoxyguanosine (8OHdG), 8-Isoprostanes (IsoP), glutathione (GSH), superoxide dismutase (SOD) activity and Tß4. In addition, plasma was used to stimulate human vascular endothelial cells (HUVEC), which were examined for cell viability, mitochondrial membrane potential, reactive oxygen species (ROS) and mitochondrial ROS (MitoROS) release. Results: At T1, in LSP group we did not detect the increase of plasma TBARS and IsoP, which was observed in control. Also, plasma levels of 8OHdG were lower in LSP group vs control. In addition, LSP group only showed an increase of plasma GSH and SOD activity. Moreover, plasma levels of Tß4 were more preserved in LSP group. Finally, at T1, in HUVEC treated with plasma from LSP group only we found an increase of the mitochondrial membrane potential and a reduction of ROS and MitoROS release in comparison with T0. Conclusions: The results of this study showed that a short LSP in older persons exerts antiaging effects by modulating oxidative stress also at cellular levels. Implications of those findings could be related to both prognostic and therapeutic strategies, which could be pursued as antiaging methods.

RESUMEN

Global warming poses a significant threat to our planet, with the food sector contributing up to 37% of total greenhouse gas emissions. This study aimed to assess the climate change impact and healthiness of menus in a long-term care facility in Italy. We analyzed two 28-day cyclical menus using the carbon footprint (CF) and the Modified EAT-Lancet Diet Score (MELDS) to evaluate adherence to the Planetary Health Diet (PHD). Monte Carlo simulations were employed to explore 20,000 daily menu permutations. Results showed that the mean GHGEs of spring/summer and autumn/winter daily menus were 2.64 and 2.82 kg of CO2eq, respectively, with 99% of menus exceeding the 2.03 kg of CO2eq benchmark. Only 22% of menus were adherent to the PHD, with MELDSs ranging from 12 to 29. A strong inverse association between the CF and adherence to the PHD was observed. These findings suggest significant potential for reducing the CFs of meals served in nursing homes while promoting adherence to a planetary diet, presenting an opportunity to set new standards in caregiving and environmental sustainability.

RESUMEN

PURPOSE: Lifestyle medicine interventions combining physical, nutritional, and psychological components have been found effective in general older population. However, evidence from the long-term care (LTC) is scarce. METHODS: We conducted a pragmatic, two-arm, parallel group, superiority randomized controlled trial. Residents living in a LTC facility for one or more years, able to discern and to express informed consent, and requiring nursing care were considered eligible. The three-months intervention combined bi-weekly physical exercise groups, a healthy diet, and weekly psychological wellbeing sessions. Patients of the control group were subjected to routine care. At the end of the study participants were assessed using Barthel Index, Katz Activities of Daily Living, and Tinetti scales. RESULTS: A total of 54 patients with a mean age of 84 years took part to the study. Physical exercise and psychological wellbeing sessions were mostly attended by all the subjects of the intervention group. Both groups took less calories than planned in the diets; in addition, the intervention group showed a lower energy and carbohydrates intake than the control group. At the end of the study, the intervention group showed a significant improvement in the total scores of all the scales. CONCLUSIONS: This intervention was effective in improving functionality in older people living in the LTC setting. Results were achieved in a short timeframe, likely due to synergistic interactions between components. However, a further exploration of underlying factors is needed, to better understand the barriers that hampered a complete intervention delivery in this context.

RESUMEN

Despite long-term care (LTC) workers having been identified as particularly subject to chronic stress, only a few studies evaluated the impact of the COVID-19 pandemic on stress in this population. As far as the authors know, no studies have investigated the relationship between work-related stress and chronic stress in the LTC setting. This retrospective observational study aimed to assess the level of chronic stress in LTC workers, to identify some possible predictors and vulnerability factors, and to measure the impact of the COVID-19 pandemic on work-related stress. The study was based on the information gathered from two different questionnaires administered before and one year after the beginning of the pandemic, to a cohort of Italian LTC workers. We found that chronic stress was associated with lower resilience to stress scores (57.42 vs. 60.66) and with higher work-related stress scores (30.48 vs. 20.83). Interestingly, the overall level of work-related stress did not differ between the two questionnaires (27.84 vs. 29.08). However, the main components of the questionnaires changed; fatigue and burnout symptoms became more relevant after the pandemic. Results of this study suggests deepening knowledge of the components of stress to develop and implement effective stress mitigation interventions.

RESUMEN

The relation between alcohol consumption and mortality is a J-shaped curve in most of the many studies published on this topic. The Copenhagen Prospective Population Studies demonstrated in the year 2000 that wine intake may have a beneficial effect on all cause mortality that is additive to that of alcohol. Wine contains various poliphenolic substances which may be beneficial for health and in particular flavonols (such as myricetin and quercetin), catechin and epicatechin, proanthocyanidins, anthocyanins, various phenolic acids and the stilbene resveratrol. In particular, resveratrol seems to play a positive effect on longevity because it increases the expression level of Sirt1, besides its antioxidant, anti-inflammatory and anticarcinogenic properties. Moderate wine drinking is part of the Mediterranean diet, together with abundant and variable plant foods, high consumption of cereals, olive oil as the main (added) fat and a low intake of (red) meat. This healthy diet pattern involves a "Mediterranean way of drinking," that is a regular, moderate wine consumption mainly with food (up to two glasses a day for men and one glass for women). Moderate wine drinking increases longevity, reduces the risk of cardiovascular diseases and does not appreciably influence the overall risk of cancer.

RESUMEN

The aim of this study is to evaluate the efficacy of a dietary supplementation with an extract from Cynara scolymus (Cs) on the glucose pattern in a group of patients with naïve impaired fasting glycaemia (IFG). A randomized, double-blind, placebo-controlled trial has been performed in 55 overweight subjects with IFG (fasting blood glucose [FBG]: 6.11 ± 0.56 mmol/l). These subjects were randomly assigned to supplement their diet with either an extract from Cs (600 mg/d) (26 subjects) or placebo (29 matched subjects) for 8 weeks. The decrease of FBG was the primary endpoint. The assessment of Homeostatic Metabolic Assessment (HOMA), glycosylated haemoglobin, A1c-Derived Average Glucose (ADAG), lipidic pattern and anthropometric parameters were the secondary endpoints. The within groups and percent changes from baseline were analyzed by the signed rank test. The comparison between groups was performed by Wilcoxon's two sample test. The supplemented group had significant decreases of: FBG (-9.6%), HOMA (-11.7%), glycosylated haemoglobin (-2.3%), ADAG (-3.1%) and lipidic pattern. The placebo group did not show any significant difference. Compared with the placebo, the supplemented group showed a significant difference in FBG, HOMA and lipidic pattern. These data demonstrate the efficacy of Cs extract on the reduction of glycometabolic parameters in overweight subjects with IFG.

RESUMEN

OBJECTIVE: A combination of bioactive food ingredients (capsaicinoids, epigallocatechin gallate, piperin, and l-carnitine, CBFI) may promote satiety and thermogenesis. The study was conducted in order to assess whether there is any effect on satiety, resting energy expenditure (REE), respiratory quotient, glucagon-like peptide-1 (GLP-1), free fatty acids (FFA) and glycerol release, following a standardized mixed meal with or without single consumption of a CBFI. DESIGN: An 8-week randomized double-blind placebo-controlled trial. SETTING: Dietetic and Metabolic Unit, Azienda di Servizi alla Persona, University of Pavia and "Villa delle Querce" Clinical Rehabilitation Institute, Rome, Italy. PARTICIPANTS: Thirty-seven overweight adults (body mass index [BMI]: 25-35). INTERVENTION: Nineteen overweight subjects were included in the supplemented group (14 women, 5 men; age 46.4 ± 6.4; BMI: 30.5 ± 3.3) and 18 in the placebo group (13 women, 5 men; age 40.8 ± 11.5; BMI: 30.1 ± 2.6). Satiety was assessed using 100-mm visual analogue scales (VAS) and the area under the curve was calculated. RESULTS: All measured parameters increased significantly in comparison with baseline in response to meal, both with CBFI and with placebo. However, throughout the study day, the supplemented group experienced a significantly greater increase than the placebo group in their sensation of satiety following acute administration of the supplement. CONCLUSION: CBFI may therefore be of great value in the treatment of overweight patients by increasing satiety and stimulating thermogenesis.

RESUMEN

The artichoke, Cynara scolymus, is one of the most ancient plants grown in the world, and its extracts, obtained from different parts of the plant (leaves, fruits and roots), have been used as medicaments from time immemorial. The pharmacological and therapeutic effects of the artichoke on the liver had already been well known in the 17th century. Modern studies started in the last century confirmed the stimulating properties of artichoke extracts on the liver and gallbladder. The ensuing wave of research was initially focused on the patent liver-stimulating, diuretic and choleretic effects exerted by artichoke preparations on both animals and man, then discovering such other therapeutic properties as the hypolipemizing activity, antioxidant activity and hypoglycemizing activity. This review enumerates the most significant studies that have highlighted these therapeutic properties. Complementary medicine information needs to be incorporated into clinical practice and patient and professional education, in addition to adequate education about proper nutrition. Awareness of the widespread use of complementary and alternative medicine by people with metabolic disorders is crucial for healthcare professionals in order to prevent cardiovascular disease.

RESUMEN

Background. The prevalence of overweight and obesity is increasing and represents a primary health concern. Body composition evaluation is rarely performed in overweight/obese subjects, and the diagnosis is almost always achieved just considering body mass index (BMI). In fact, whereas BMI can be considered an important tool in epidemiological surveys, different papers stated the limitations of the use of BMI in single individuals. Aim. To assess the determinants of body composition in overweight and obese subjects. Methods. In 103 overweight or obese subjects (74 women, aged 41.5 ± 10 years, and 29 men, aged 43.8 ± 8 years), a multidimensional evaluation was performed including the assessment of body composition using Dual Energy X-Ray Absorptiometry (DXA), anthropometry, bioimpedance analysis (BIA), and biochemical parameters (total cholesterol, triacylglycerol, HDL- and LDL-cholesterol, free fatty acids and glycerol, glucose, insulin, C-reactive protein, plasma acylated and unacylated ghrelin, adiponectin, and leptin serum levels). Results. BMI does not represent the main predictor of FM estimated by DXA; FM from BIA and hip circumference showed a better association with FM from DXA. Moreover, models omitting BMI explained a greater part of variance. These data are confirmed by the predictive value analysis where BMI showed a performance similar to a "coin flip."

RESUMEN

Osteoporosis is a leading cause of morbidity and mortality in the elderly and influences quality of life, as well as life expectancy. Currently, there is a growing interest among the medical scientists in search of specific nutrients and/or bioactive compounds of natural origin for the prevention of disease and maintenance of bone health. Although calcium and vitamin D have been the primary focus of nutritional prevention of osteoporosis, a recent research has clarified the importance of several additional nutrients and food constituents. Based on this review of the literature, supplementation with vitamins B, C, K, and silicon could be recommended for proper maintenance of bone health, although further clinical studies are needed. The results of studies on long-chain polyunsaturated fatty acids, potassium, magnesium, copper, selenium, and strontium are not conclusive, although studies in vitro and in animal models are interesting and promising.

RESUMEN

The aim of this study was to evaluate the effects of artichoke leaf extract (ALE) supplementation (250 mg, 2 b.i.d.) on the lipid pattern. A randomized, double-blind, placebo-controlled clinical trial was performed on 92 overweight subjects with primary mild hypercholesterolaemia for 8 weeks. Forty-six subjects were randomized to supplementation (age: 54.2 ± 6.6 years, body mass index (BMI): 25.8 ± 3.9 kg/m(2), male/female: 20/26) and 46 subjects to placebo (age: 53.8 ± 9.0 years, BMI: 24.8 ± 1.6 kg/m(2), male/female: 21/25). Verum supplementation was associated with a significant increase in mean high-density lipoprotein (HDL)-cholesterol (p < 0.001) and in mean change in HDL-cholesterol (HDL-C) (p = 0.004). A significantly decreased difference was also found for the mean change in total cholesterol (p = 0.033), low-density lipoprotein (LDL)-cholesterol (p < 0.001), total cholesterol/HDL ratio (p < 0.001) and LDL/HDL ratio (p < 0.001), when verum and placebo treatment were compared. These results indicate that ALE could play a relevant role in the management of mild hypercholesterolaemia, favouring in particular the increase in HDL-C, besides decreasing total cholesterol and LDL-cholesterol.

RESUMEN

This randomized, double blind, placebo-controlled, 8 week trial assessed the efficacy on metabolic changes produced by a consumption of a combination of bioactive food ingredients (epigallocatechin gallate, capsaicins, piperine and L-carnitine) versus a placebo, as part of a therapeutic 'lifestyle change' diet, in 86 overweight subjects. Forty-one patients (2/14 F/M; age 43.7 ± 8.5; BMI 30.3 ± 3.5 kg/m(2)) were randomized to the supplemented group and 45 (29/16; age 40.7 ± 10.2; BMI 30.0 ± 2.7) to the control group. We observed that consumption of the dietary supplement was associated with a significantly greater decrease in insulin resistance, assessed by homostasis model assessment (p < 0.001), leptin/adiponectin ratio (p < 0.04), respiratory quotient (p < 0.008). LDL-cholesterol levels (p < 0.01). Moreover, statistically significant differences were recorded between the two groups in relation to urinary norepinephrine levels (p < 0.001). Leptin, ghrelin, C-reactive protein decreased and resting energy expenditure increased significantly in the supplemented group (p < 0.05, 0.03, 0.02 and 0,02 respectively), but not in the placebo group; adiponectin decreased significantly in the placebo group (0.001) but not in the supplemented group, although no statistical significance between the groups was elicited. BMI, fat mass (assessed by DXA) and vascular endothelial growth factor significantly decreased, whilst the resting energy expenditure/free fat mass significantly increased in both groups. In general, a greater change was recorded in the supplemented group compared to the placebo, although no statistically significant difference between the two groups was recorded. These results suggest that the combination of bioactive food ingredients studied might be useful for the treatment of obesity-related inflammatory metabolic dysfunctions.

RESUMEN

BACKGROUND: Depression is one of the most frequently missed diagnoses in elderly people, with obvious negative effects on quality of life. Various studies have shown that long chain omega-3 polyunsaturated fatty acids (n-3 PUFA) may be useful in its management. Our objective was to evaluate whether a supplement containing n-3 PUFA improves depressive symptoms in depressed elderly patients, and whether the blood fatty acid pattern is correlated with these changes. METHODS: The severity of depressive symptoms according to the Geriatric Depression Scale (GDS), blood fatty acid composition and erythrocyte phospholipids were analyzed in 46 depressed females aged 66-95y, diagnosed with depression according to DSMIV, within the context of a randomized, double-blind, placebo-controlled trial. 22 depressed females were included in the intervention group (2.5 g/day of n-3 PUFA for 8 weeks), and 24 in the placebo group. We also measured immunological parameters (CD2, CD3, CD4, CD8, CD16, CD19 and cytokines (IL-5, IL-15). RESULTS: The mean GDS score and AA/EPA ratio, in whole blood and RBC membrane phospholipids, were significantly lower after 2 months supplementation with n-3 PUFA. A significant correlation between the amelioration of GDS and the AA/EPA ratio with some immunological parameters, such as CD2, CD19, CD4, CD16 and the ratio CD4/CD8, was also found. Nevertheless, omega-3 supplementation did not significantly improve the studied immunological functions. CONCLUSIONS: n-3 PUFA supplementation ameliorates symptoms in elderly depression. The n-3 PUFA status may be monitored by means of the determination of whole blood AA/EPA ratio.

RESUMEN

Age-related changes in nutritional status can play an important role in brain functioning. Specific nutrient deficiencies in the elderly may exacerbate pathological processes in the brain. Consequently, the potential of nutritional intervention to prevent or delay cognitive impairment and the development of dementia is an important topic. A randomized, double-blind, placebo-controlled trial has been performed in 25 elderly subjects (86 ± 6 years, 20 females, 5 males) with mild cognitive impairment (MCI). These subjects were randomly assigned to supplement their diet with either an oily emulsion of docosahexaenoic acid (DHA)-phospholipids containing melatonin and tryptophan (11 subjects) or a placebo (14-matched subjects) for 12 weeks. The main aim of this study was to evaluate the efficacy of the dietary supplement on cognition, by the assessment at the start and after 12 weeks of: (1) Orientation and other cognitive functions: Mini-Mental State Examination (MMSE); (2) Short-term memory: digit, verbal, and spatial span (digit span; verbal span; Corsi's test); (3) Long-term memory: Rey's auditory-verbal learning test; 'short story' test; Rey-Osterrieth complex figure (recall); (4) Attentional abilities: attentive matrices; (5) Executive functions: Weigl's sorting test; phonological fluency 'FAS'; (6) Visuo-constructional and visuo-spatial abilities: copy of simple drawings; Rey-Osterrieth complex figure (copy); (7) Language: semantic fluency; (8) Mood: Geriatric Depression Scale (GDS). Moreover, Sniffin' Sticks olfaction test and Mini Nutritional Assessment (MNA) have been performed. After 12 weeks, a significant treatment effect for the MMSE (P < 0.001) and a positive trend for the semantic verbal fluency was found in the supplement group (P < 0.06). A significant treatment effect was found out for the olfactory sensitivity assessment (P < 0.009). As regards the nutrition evaluation, after 12 weeks of treatment the supplemented group showed an improvement in the MNA score with a significant difference relative to placebo (P < 0.005). Older adults with MCI had significant improvements in several measures of cognitive function when supplemented with an oily emulsion of DHA-phospholipids containing melatonin and tryptophan for 12 weeks, compared with the placebo.

RESUMEN

BACKGROUND & AIMS: Several tools are available for nutritional screening. We evaluated the risk of mortality associated with the Geriatric Nutritional Risk Index (GNRI) and the Mini Nutritional Assessment (MNA) in newly institutionalised elderly. METHODS: A prospective observational study involving 358 elderly newly admitted to a long-term care setting. Hazard ratios (HR) for mortality among GNRI categories and MNA classes were estimated by multivariable Cox's model. RESULTS: At baseline, 32.4% and 37.4% of the patients were classified as being malnourished (MNA <17) and at severe nutritional risk (GNRI <92), respectively, whereas 57.5% and 35.2%, respectively, were classified as being at risk for malnutrition (MNA 17-23.5) and having low nutritional risk (GNRI 92-98). During a median follow-up of 6.5 years [25th-75th percentile, 5.9-8.6], 297 elderly died. Risk for all-cause mortality was significantly associated with nutritional risk by the GNRI tool (GNRI<92 HR = 1.99 [95%CI, 1.38-2.88]; GNRI 92-98 HR = 1.51 [95%CI, 1.04-2.18]) but not with nutritional status by the MNA. A significant association was also found with cardiovascular mortality (GNRI <92 HR = 1.79 [95%CI, 1.23-2.61]). CONCLUSIONS: Nutritional risk by GNRI but not nutritional status by MNA was associated with higher mortality risk. Present data suggest that in the nutritional screening of newly institutionalised elderly the use of the GNRI should be preferred to that of the MNA.

RESUMEN

Rice (Oryza Sativa) bran, comprising 10% of the total rice grain, is a by-product of the rice milling industry with world production of about 50-60 million metric tons per year. Rice bran is an excellent source of antioxidants, vitamins, fatty acids, protein, carbohydrates and other critical minerals and nutrients. In addition to being an excellent source of nutrients, rice bran is reported to be rich in phytonutrients that provide health benefits associated with blood sugar control, cholesterol metabolism, prostate health and chemoprevention. This paper focus on these phytonutrients and their effect on health.

RESUMEN

BACKGROUND & AIMS: This study assessed the efficacy of supplemented essential amino acids on depressive symptoms, nutrition, muscle function, daily physical activity, and health-related quality of life (HRQoL) of institutionalized elderly patients. METHODS: Forty-one patients (58.5% women; mean age 79.8 yrs) with sequelae of coronary artery disease (73%), femoral fracture (34%), were randomly assigned to receive oral essential amino acids 4 gr 2 times a day for 8 weeks or isocaloric placebo. Before randomization and 8 weeks after the protocol started, the following variables were measured: depressive symptoms (Geriatric Depression Scale, GDS), nutritional panel (Mini Nutritional Assessment, MNA; serum albumin and prealbumin levels), muscle strength (Hand Grip, HG), Activity Daily Life (ADL), Quality of Life (SF-36, HRQoL) and amino acid profile. RESULTS: Compared with the placebo group, EAA patients improved nutrition (MNA score 22.6 ± 1.5 post vs 21.8 ± 1.6 pre; p < 0. 04, albumin g/dl 4.04 ± 0.35 post vs 3.88 ± 0.3 pre; p < 0.01), GDS(score 10.3 ± 1.75 post vs 13.85 ± 3.37 pre; p < 0.001), HG (Kg 19.75 ± 1.7 post vs 18.68 ± 1.36 pre; p = 0.001), ADL (p < 0.04) and both physical and mental components of SF-36 (p < 0.002). CONCLUSIONS: Oral supplementation with essential amino acids improved several determinants of quality of life in institutionalized elderly patients, including depressive symptoms, nutrition, muscle function and daily life activity.

RESUMEN

OBJECTIVE: Malnutrition and sarcopenia in institutions are very common and significantly affect the prognosis. Aging is characterized by weight and lean body mass losses. Accordingly, in elderly patients, body mass index (BMI) is considered a marker of protein stores rather than of adiposity. Current guidelines suggest a BMI 21 kg/m(2) or lower as major trigger for nutritional support. We evaluated the association between BMI and mortality in institutionalized elderly. METHODS: This was a multicentric prospective cohort study involving 519 long-term care resident elderly individuals. Risk for mortality across BMI tertiles was estimated by the Cox hazards regression model adjusted for potential confounders recorded at inclusion and collected during the follow-up. RESULTS: During a median follow-up of 5.7 years (25th to 75th percentile, 5.2-8.2], 409 (78.8%) elderly patients died. In primary analyses, based on variables collected at inclusion, patients in the first tertile of BMI (≤ 21 kg/m(2)) were at higher risk for all-cause (hazard ratio [HR] 1.38; 95% confidence interval [CI] 1.04-1.84; P = .025) and cardiovascular mortality (HR = 1.49; 95% CI, 1.00-2.08; P = .045). Increased risk was confirmed even after adjusting for nutritional support during the follow-up (all-cause HR = 1.53; 95% CI, 1.13-2.06; P = .006; cardiovascular HR = 1.62; 95% CI, 1.09-2.40; P = .018), which in turn was associated with a reduced risk (all-cause HR = 0.74; 95% CI, 0.55-0.97; P = .035; cardiovascular HR = 0.62; 95% CI, 0.42-0.91; P = .016). CONCLUSION: BMI is significantly associated with all-cause and cardiovascular mortality in institutionalized elderly patients. A value of 21 kg/m(2) or lower can be considered a useful trigger for nutritional support. These results support intending BMI as nutritional reserve in institutionalized elderly patients.

RESUMEN

The management of overweight may include the use of dietary supplements targeted to favour the increase of the satiation associated with a decrease in blood glucose and lipid levels. The aim of this study was to evaluate the efficacy of a dietary supplementation with an extract from Phaseolus vulgaris and Cynara scolymus, on satiation, the glucose and lipid pattern. A randomized, double-blind, placebo-controlled clinical trial was performed in 39 overweight subjects (20 supplemented group, 19 placebo group) for 2 months. The modification of satiation, by Haber's scale, was the primary end-point, and the variation of the glucose and lipid pattern, of the anthropometric parameters and of the psychodynamic tests score were the secondary end-points. At the end of treatment, the net change of the Haber's mean score increased significantly in the intervention group. The net change of the glycaemia and of the dietary restriction score of the three factor eating questionnaire (TFEQ), were reduced significantly only in the intervention group. Moreover, in the supplemented group, the homeostasis model assessment, the body mass index and the susceptibility-to-hunger score of the TFEQ, decreased significantly after intervention; these parameters did not change in the controls. This treatment appears potentially useful in the management of overweight and dysglycaemia.

RESUMEN

OBJECTIVES: To determine whether nightly administration of melatonin, magnesium, and zinc improves primary insomnia in long-term care facility residents. DESIGN: Double-blind, placebo-controlled clinical trial. SETTING: One long-term care facility in Pavia, Italy. PARTICIPANTS: Forty-three participants with primary insomnia (22 in the supplemented group, 21 in the placebo group) aged 78.3 ± 3.9. INTERVENTION: Participants took a food supplement (5 mg melatonin, 225 mg magnesium, and 11.25 mg zinc, mixed with 100 g of pear pulp) or placebo (100 g pear pulp) every day for 8 weeks, 1 hour before bedtime. MEASUREMENTS: The primary goal was to evaluate sleep quality using the Pittsburgh Sleep Quality Index. The Epworth Sleepiness Scale, the Leeds Sleep Evaluation Questionnaire (LSEQ), the Short Insomnia Questionnaire (SDQ), and a validated quality-of-life instrument (Medical Outcomes Study 36-item Short Form Survey (SF-36)) were administered as secondary end points. Total sleep time was evaluated using a wearable armband-shaped sensor. All measures were performed at baseline and after 60 days. RESULTS: The food supplement resulted in considerably better overall PSQI scores than placebo (difference between groups in change from baseline PSQI score=6.8; 95% confidence interval=5.4-8.3, P<.001). Moreover, the significant improvements in all four domains of the LSEQ (ease of getting to sleep, P<.001; quality of sleep, P<.001; hangover on awakening from sleep, P=.005; alertness and behavioral integrity the following morning, P=.001), in SDQ score (P<.001), in total sleep time (P<.001), and in SF-36 physical score (P=.006) suggest that treatment had a beneficial effect on the restorative value of sleep. CONCLUSION: The administration of nightly melatonin, magnesium, and zinc appears to improve the quality of sleep and the quality of life in long-term care facility residents with primary insomnia.
