Abstract
BACKGROUND & AIMS the obesity survival paradox is an emergent issue in oncology, but its existence remains unclear particularly in older cancer patients. We aimed to assess the obesity survival paradox in older cancer patients. METHODS all consecutive cancer outpatients 65 years and older referred for geriatric assessment (GA) before a decision on cancer treatment between November 2013 and September 2016 were enrolled in the PF-EC cohort study. The main outcome was 6-month mortality. A Cox univariate and multivariate proportional hazard regression models were performed with baseline GA, oncological variables (cancer site, extension and treatment modalities) and C-reactive protein (CRP). We assessed the prognostic value of body mass index categories (i.e. malnutrition <21, 21 ≤ normal weight ≤24.9, 25 ≤ overweight ≤29.9 and obesity ≥30 kg/m2) in the whole study population and according to the metastatic status. RESULTS 433 patients with a mean age of 81.2 ± 6.0 years were included, 51% were women, 44.3% had digestive cancers, 18% breast cancer and 14.5% lung cancer and 45% metastatic cancers. Eighty-eight of these patients (20.3%) were obese at baseline. Mortality rate was 17% during the 6-month follow-up period. After adjustment for sex, gait speed, Mini-Mental State Examination, cancer site and exclusive supportive care, obesity (compared to normal weight) was independently and negatively associated with 6-month mortality only in metastatic patients (aHR 0.17, 95% CI [0.03-0.92], P = 0.04). CONCLUSION our study confirms the obesity survival paradox in older cancer patients only in the metastatic group.

Abstract
The impact of vitamin D deficiency on the recovery of patients with malnutrition remains undefined. Our aim was to study the prevalence of vitamin D deficiency in a well-characterized cohort of patients with malnutrition and its association with outcomes.Within this secondary analysis of a randomized controlled trial, we examined the association of vitamin D deficiency and adverse clinical outcomes over a follow-up of 180 days in hospitalized patients at risk for malnutrition. We measured 25-hydroxyvitamin D levels upon admission and defined Vitamin D deficiency when levels were <50nmol/l. The primary endpoint was 180-day mortality.The prevalence of vitamin D deficiency in our cohort of 828 patients was 58.2% (n = 482). Patients with vitamin D deficiency had increased 180-day mortality rates from 23.1% to 29.9% (odds ratio 1.42, 95% confidence interval [CI] 1.03-1.94, P = .03). When adjusting the analysis for demographics, comorbidities, and randomization, this association remained significant for the subgroup of patients not receiving vitamin D treatment (adjusted odds ratio 1.63, 95% CI 1.01-2.62, P = .04). There was no significantly lower risk for mortality in the subgroup of vitamin D deficient patients receiving vitamin D treatment compared to not receiving treatment (adjusted odds ratio 0.74, 95% CI 0.48-1.13, P = .15).Vitamin D deficiency is highly prevalent in the population of malnourished inpatients and is negatively associated with long-term mortality particularly when patients are not receiving vitamin D treatment. Our findings suggest that malnourished patients might benefit from vitamin D screening and treatment in case of deficiency.

Abstract
OBJECTIVES The objective of this study was to assess the effects of a hyperproteic, hypercaloric oral nutritional supplement with prebiotic fiber, vitamin D, and calcium, plus a standardized physical intervention, in the functional status, strength, nutritional status, and quality of life of frail institutionalized older adults. DESIGN Multicentric prospective observational study under usual clinical practice conditions. SETTING Four nursing homes from Burgos (2), Albacete, and Madrid, Spain. PARTICIPANTS Participants included 91 institutionalized older adults (age ≥70), able to walk 50 m, and meeting at least 3 of the Fried frailty phenotype criteria. INTERVENTION Daily intake of two 200-mL bottles of an oral nutritional supplement, each bottle containing 300 kcal, 20 g protein, 3 g fiber, 500 IU vitamin D, and 480 mg calcium, plus a standardized physical exercise training consisting of flexibility, balance, and strengthening exercises for arms and legs, 5 days per week. MEASUREMENTS Short Physical Performance Battery (SPPB), Short-Form-Late-Life Function and Disability Instrument (SF-LLFDI) function subscale, handgrip strength, EuroQoL-5 Dimensions visual analogic scale (EQ5DVAS), weight, body mass index (BMI), and Short-Form Mini Nutritional Assessment (MNA-SF) at baseline and 6 and 12 weeks. RESULTS Forty-eight participants (52.7%) improved at least 1 point in the SPPB at week 6, and 44 (48.4%) did so at week 12; 39 participants (42.9%) improved at least 2 points in the SF-LLFDI at week 6, and 46 (50.5%) at week 12. Participants improved their quality of life measured with the EQ5DVAS by 6% (95% confidence interval [CI] 3%-10%) at week 6, and by 5% (95% CI 0%-10%) at week 12. They also improved their nutritional status (weight gain, BMI increase, and higher MNA-SF scores at 6- and 12-week follow-up). This improvement was higher in participants with more frailty criteria, lower functional level, lower vitamin D levels, and poorer nutritional status. CONCLUSION A 12-week intervention with oral nutritional supplementation plus physical exercise improves function, nutritional status, and quality of life in frail institutionalized older adults.

Abstract
AIM: Increasing evidence from experimental studies and clinical observations suggests that drugs with anticholinergic properties can cause physical and mental impairment. The aim of the present study was to evaluate the relationship between the use of drugs with anticholinergic activity and negative outcomes in older nursing home residents. METHODS We used data from the database of the U.L.I.S.S.E project (Un Link Informatico sui Servizi Sanitari Esistenti per l'Anziani), a prospective multicenter observational study. Patients from 31 facilities in Italy were assessed at baseline and at 6 and 12 months by trained personnel, using the Minimum Data Set for Nursing Home (MDS-NH). The only exclusion criterion was age younger than 65 years. The Anticholinergic Risk Scale (ARS), a list of commonly prescribed drugs with potential anticholinergic effects, was used to calculate the anticholinergic load. RESULTS A total population of 1490 patients was analyzed; almost half of the sample (48%) was using drugs with anticholinergic properties. The population of patients with ARS 1 or higher had a higher comorbidity index (P < .003) and greater cognitive impairment (CPS 5-6) (P < .007). They were more likely to suffer from heart failure, Parkinson disease, depression, anxiety, and schizophrenia. In multivariate analysis, a higher score in the ARS scale was associated with a greater likelihood of functional decline (described as the loss of ≥1 ADL point) (odds ratio [OR] 1.13; confidence interval [CI] 1.03-1.23), to a higher rate of falls (OR 1.26; CI 1.13-1.41), and to a higher incidence of delirium (OR 1.16; CI 1.02-1.32) during a 1-year follow-up. CONCLUSIONS The use of medications with anticholinergic properties is common among older nursing home residents. Our results suggest that among older nursing home residents the use of anticholinergic drugs is associated with important negative outcomes, such as functional decline, falls, and delirium.
