Cardiorespiratory fitness and all-cause mortality in adults diagnosed with cancer systematic review and meta-analysis.

2021

INTRODUCTION The inverse association between cardiorespiratory fitness and all-cause mortality in apparently healthy populations has been previously reported; however, the existence of this association among adults diagnosed with cancer is unclear. AIM To determine the association between cardiorespiratory fitness and all-cause mortality in adults diagnosed with cancer. METHODS Medline, Embase, and SPORTDiscus databases were searched. Eligible prospective cohort studies that examined the association of cardiorespiratory fitness with all-cause mortality in adults diagnosed with cancer were included. Hazard ratios (HRs) with associated 95% confidence intervals (CIs) were extracted from studie…

Clinical effectiveness of different natalizumab interval dosing schedules in a large Italian population of patients with multiple sclerosis

2020

IntroductionNatalizumab (NTZ) is one of the most effective treatment options for multiple sclerosis (MS) treatment. Our study aimed to evaluate the effectiveness of NTZ when administered according to the extended dosing strategy compared with standard 4-weekly administration in a large Italian MS population.Materials and methodsThis retrospective multicentre study included patients with relapsing-remitting MS (RR-MS) who received NTZ administrations between the 1 June 2012 and the 15 May 2018 and were followed by the ‘Italian MS Register’. All patients with MS were stratified into two groups based on NTZ administration schedule: standard interval dosing (SID) patients who received infusions…

Comorbidity-dependent adherence to guidelines and survival in breast cancer-Is there a role for guideline adherence in comorbid breast cancer patient…

2016

In the treatment of breast cancer, decisions on adjuvant treatment reflect individual patient characteristics like age and comorbidity. This study assessed the association between adherence to guidelines for adjuvant treatment and survival while taking into account age at diagnosis and comorbidities. We collected the Charlson comorbidity index at baseline for 2179 women treated for primary breast cancer from 1992 to 2008 who participated in a German retrospective multicenter cohort study. We assessed subsequent adjuvant therapy guideline adherence and survival in relation to baseline comorbidities. Guidelines for adjuvant chemotherapy and radiotherapy were more often violated in patients wi…

Satisfaction With Present Life Predicts Survival in Octogenarians

2006

We examined the effect of life satisfaction on survival over 10 years among 80-year-old and older same-sex twins of whom 320 individuals responded to the Life Satisfaction Index Z questionnaire in connection with the OCTO-Twin study. We treated participants as individuals in semiparametric Cox regression mixed-effects models (frailty) by adjusting the similarity of mortality risk within twin pairs by modeling it as a random variable. An exploratory factor analysis yielded three factors: Zest and Mood represented satisfaction with present life and Congruence represented satisfaction with past life. Those in the lowest quartile of factors of satisfaction with present life had an almost twofol…

Social frailty increases the risk of all-cause mortality: A longitudinal analysis of the English Longitudinal Study of Ageing

2022

Objectives\ud Social frailty is a common condition in older people, but its consequences are largely unknown. Therefore, in this longitudinal analysis, we aimed to investigate the association between social frailty and risk of all-cause mortality in a large sample of older people.\ud Design\ud Longitudinal, cohort.\ud Settings and participants\ud Older people participating to the English Longitudinal Study of Ageing (ELSA).\ud Methods\ud Social frailty was defined based on financial difficulty, household status, social activity, and contacts with other people: social frailty was defined as ≥2 points, social pre-frailty (1 point), and robustness (0 points). Survival status during ten years o…

Development and validation of prediction model to estimate 10-year risk of all-cause mortality using modern statistical learning methods: a large pop…

2021

Abstract Background In increasingly ageing populations, there is an emergent need to develop a robust prediction model for estimating an individual absolute risk for all-cause mortality, so that relevant assessments and interventions can be targeted appropriately. The objective of the study was to derive, evaluate and validate (internally and externally) a risk prediction model allowing rapid estimations of an absolute risk of all-cause mortality in the following 10 years. Methods For the model development, data came from English Longitudinal Study of Ageing study, which comprised 9154 population-representative individuals aged 50–75 years, 1240 (13.5%) of whom died during the 10-year follo…

Coimpairments as Predictors of Severe Walking Disability in Older Women

2001

OBJECTIVE: Severe disabilities are common among older people who have impairments in a range of physiologic systems. It is not known, however, whether the presence of multiple impairments, or coimpairments, is associated with increased risk of developing new disability. The aim of this study was to determine the combined effects of two impairments, decreased knee-extension strength and poor standing balance, on the risk of developing severe walking disability among older, moderately-to-severely disabled women who did not have severe walking disability at baseline. DESIGN: The Women's Health and Aging Study is a 3-year prospective study with 6 semi-annual follow-up data-collection rounds fol…

Combined resistance and balance-jumping exercise reduces older women's injurious falls and fractures: 5-year follow-up study

2014

BACKGROUND AND OBJECTIVE: previously, a randomised controlled exercise intervention study (RCT) showed that combined resistance and balance-jumping training (COMB) improved physical functioning and bone strength. The purpose of this follow-up study was to assess whether this exercise intervention had long-lasting effects in reducing injurious falls and fractures. DESIGN: five-year health-care register-based follow-up study after a 1-year, four-arm RCT. SETTING: community-dwelling older women in Finland. SUBJECTS: one hundred and forty-five of the original 149 RCT participants; women aged 70-78 years at the beginning. METHODS: participants' health-care visits were collected from computerised…

Comparison of the activity, selectivity and decay properties of lay and hyultrastable zeolites during the cracking of alkanes

1984

Abstract The cracking of n-heptane on LaY ultrastable zeolite has been studied in a continuous glass flow reactor, at atmospheric pressure, up to 470°C. The initial selectivity to cracking, isomerization and disproportionation, kinetic rate constants, activation energies and decay parameters have been calculated and compared with those obtained using a HY ultrastable zeolite as a catalyst. It has been found that the HY ultrastable zeolite is about 7 times more active for cracking, and about 10 times more active for isomerization and disproportionation than the LaY ultrastable zeolite. The protolytic to β-cracking ratio is higher for the HY ultrastable zeolite. The deactivation takes place b…
