Accurate estimation of energy requirements is crucial for health maintenance and prevention of malnutrition in older adults. This study aimed to assess the accuracy of predictive equations for estimating energy requirements in older adults and to test the validity of new predictive equations for this age group. This is a cross-sectional study including 38 Brazilian community-dwelling older adults aged 60-84 years, who had their total energy expenditure measured by doubly labeled water (TEE ). The energy expenditure was compared to the Institute of Medicine (Dietary Reference Intake (DRI)) and Vinken et al. previous predictive equations and three predictive models developed in a modeling sample. The agreement was assessed using intra-class correlation coefficient, Bland-Altman plots, and Lin's concordance correlation. Accuracy was evaluated considering ±10% of the ratio between estimated and measured energy expenditure. The mean (standard deviation) TEE was 2656.7 (405.6)?kcal/day for men and 2168.9 (376.9) for women. Vinken et al. and both DRI equations presented moderate to good degree of agreement, while the developed models vary from fair to very good agreement in comparison to DLW. The accuracy rate was the same for both DRI equations and Vinken et al. equation (60.53%). The new equations developed in this study had accuracy in predicting TEE for Brazilian older adults varying from 43.11% to 73.68%. The results corroborate the use of previous predictive equations for estimating energy requirements in Brazilian older adults. Further studies have the potential to explore the use of the developed models to assess energy needs in this population.The results corroborate the use of previous predictive equations for estimating energy requirements in Brazilian older adults.

Guidelines for optimal sequencing of radium-223 and chemotherapy for metastatic castration resistant prostate cancer (mCRPC) do not exist. This study evaluated treatment patterns and overall survival (OS) among patients with mCRPC treated with radium-223 in an academic clinical setting. A retrospective study was conducted of bone metastases-predominant mCRPC patients treated with radium-223. Treatment patterns from 2013 to 2018 were evaluated in patients treated with radium-223 pre- vs. post-chemotherapy. OS was examined using Kaplan-Meier medians and 95% confidence intervals. In total, 220 patients were treated with radium-223 (64 pre-chemotherapy, 83 post-chemotherapy, 73 no chemotherapy). Mean radium-223 injections per patient was 5.3 and 4.3 in the pre- vs. post-chemotherapy cohorts, respectively (p?<?0.001). The number of chemotherapy cycles was similar for chemotherapy given pre- or post-radium-223. https://www.selleckchem.com/products/bi-d1870.html Mean line of mCRPC therapy of radium-223 was 3rd and 5th when given pre- and post-chemotherapy, e needed to determine the optimal sequencing strategy of mCRPC in the modern era.This retrospective analysis of patients treated with radium-223 demonstrates that administration of radium-223 pre-chemotherapy increased likelihood of completion of radium-223 treatment. Radium-223 given pre- or post-chemotherapy and with or without combination therapy did not result in significant differences in OS. Additional studies are needed to determine the optimal sequencing strategy of mCRPC in the modern era. Androgen deprivation therapy (ADT) administration was recently reported and might be positively associated with dementia. However, the existing studies showed controversial results. The aim of this study was to evaluate the relationship between ADT and the risk of dementia through a meta-analysis. Original articles published up to March 2020 were retrieved from Embase, Pubmed, the Cochrane library, and Web of Science for studies focusing on associations between ADT for prostate cancer (PCa) and incidence of dementia. A meta-analysis was conducted using a hazard ratio (HR) and 95% confidence interval (CI) as effect measures. Heterogeneity between the studies was examined using I statistics. Subgroup analyses, sensitivity analyses, and meta-regression were conducted, and publication bias was assessed by Egger's test. Thirteen studies were included in this systematic review. Eleven cohort studies involving 339,400 cases and 436,851 controls were included in the main meta-analysis. ADT administration was ssociated with increased risk. To investigate the oncologic safety of neurovascular bundles (NVB) preservation at radical prostatectomy (RP) in patients with high-risk and/or locally advanced prostate cancer (PCa). Within a two-institutional high-volume center database we identified patients who harbored high-risk PCa at RP (2000-2017). Only patients with D'Amico high-risk PCa were included. Kaplan-Meier and multivariable Cox regression models tested the effect of NVB preservation on biochemical recurrence (BCR), metastasis and overall survival (OS). Subgroup analyses focused on patients with clinical stage T3 and/or biopsy ISUP grade 5 and pathologic stage T3. Of 4351 patients with D'Amico high-risk, 35.7% vs. 38.0% vs. 26.3% underwent bilateral vs. unilateral vs. no NVB preservation, respectively. At 120 months after RP BCR-free, metastasis-free survival and OS rates were 62.2% vs. 44.3% vs. 27.1% (p?<?0.001), 83.7% vs. 66.7% vs. 60.3% (p?<?0.001), and 91.8% vs. 87.5% vs. 72.3% (p?<?0.001) for bilateral vs. unilateral vs. no NVB preservation, respectively. In multivariable Cox regression models, bilateral and unilateral compared to no NVB preservation did not increase the risk for BCR, metastasis or death in the entire cohort and in subgroups with clinical stage T3 and/or biopsy ISUP grade 5, as well as pathologic stage T3. NVB preservation was not associated with worse oncological outcome in patients with high-risk and/or locally advanced PCa and may be offered to well-selected patients who are at risk of harboring nonorgan-confined PCa.NVB preservation was not associated with worse oncological outcome in patients with high-risk and/or locally advanced PCa and may be offered to well-selected patients who are at risk of harboring nonorgan-confined PCa.
