Background: The effect of the increasing lifetime burden of non-major cardiovascular conditions on risk for a subsequent major adverse cardiovascular event among survivors of childhood cancer has not been assessed. We aimed to characterise the prevalence of major adverse cardiovascular events and their association with the cumulative burden of non-major adverse cardiovascular events in childhood cancer survivors.

Methods: This is a longitudinal cohort study with participant data obtained from an ongoing cohort study at St Jude Children's Research Hospital: the St Jude Lifetime Cohort Study (SJLIFE).

Introduction: This study aimed to assess longitudinal associations between lifestyle and subsequent malignant neoplasms (SMNs) in young adult childhood cancer survivors.

Methods: Members of the St. Jude Lifetime Cohort (SJLIFE) aged ≥18 years and surviving ≥5 years after childhood cancer diagnosis were queried and evaluated for physical activity, cardiorespiratory fitness (CRF), muscle strength, body mass index (BMI), smoking, risky drinking, and a combined lifestyle score.

Purpose: Movement efficiency, a measure of neuromuscular biomechanics, may be modified by physical activity. We aimed to assess the risk of and risk factors for low movement efficiency in survivors of childhood acute lymphoblastic leukemia (ALL).

Methods: Participants underwent an assessment of activity energy expenditure (AEE) with actigraphy, and the gold standard doubly labeled water, where the differences between elimination rates of oxygen and hydrogen from body water are evaluated over a week.

Aim: The aim of this work was to assess the effect of a short-term, home-based exercise intervention before and after colorectal cancer surgery on 12-month physical recovery within a previously reported randomized control trial (RCT).

Method: PHYSSURG-C is an RCT in six participating hospitals in Sweden. Patients aged ≥20 years planned for elective colorectal cancer surgery were eligible.

Background: Lifestyle is associated with meningioma risk in the general population.

Aims: We assessed longitudinal associations between lifestyle-associated factors and subsequent meningiomas in childhood cancer survivors.

Methods And Results: Childhood cancer survivors age ≥18 years in the St.

Objective: This study examined BMI in young men and incident site-specific cancer to estimate population attributable fractions due to BMI based on projected obesity prevalence.

Methods: A population-based cohort study with measured height and weight at age 18. Cox regression models assessed linear associations for BMI and included age, year, and site of conscription as well as parental level of education as covariates.

Background: Our aim was to assess associations between cardiorespiratory fitness (CRF) and body mass index (BMI) in youth and 5-year mortality after site-specific cancer diagnoses in men.

Methods: Men with cancer from a population who underwent military conscription at ages 16-25 during 1968-2005 in Sweden were included. CRF was assessed as maximal aerobic workload on a cycle ergometer test and was classified as low, moderate, or high.

Objectives: To assess the associations between cardiorespiratory fitness (CRF) in young men and the incidence of site-specific cancer.

Methods: A Swedish population-based cohort study with register linkage of men who underwent military conscription in 1968-2005 was undertaken. CRF was assessed by maximal aerobic workload cycle test at conscription.

Aim: There are ample discussions regarding the timing of treatment, especially in the era after Covid that caused delay to treatment. The aim of this study was to determine whether a delayed start to curative treatment, within 29-56 days after a diagnosis of colon cancer, was noninferior to starting treatment within 28 days, with regard to all-cause mortality.

Method: This is a national register-based observational noninferiority study, with a noninferiority margin of hazard ratio (HR) 1.

Background And Objective: The PhysSURG-B trial of prehabilitation before breast cancer surgery randomized patients to a nonsupervised physical activity or a control group. The effects of the intervention on short- and long-term quality of life (QoL) were examined, with a subgroup analysis of patients receiving adjuvant chemotherapy.

Methods: Female patients planned for surgery were randomly assigned to either an intervention of 30 min of self-administered physical aerobic activity daily 2 weeks before and 4 weeks after surgery or control.

Enhanced screening and efficient cancer treatments have led to a growing number of cancer survivors. In Sweden over 500 000 individuals have or have had cancer [1]. Cancer survivors can experience a wide range of disease and treatment related symptoms, that profoundly affect their health related quality of life.

Introduction: Physical activity has been suggested as a modifiable risk factor for postoperative recovery after major surgery. We aimed to further define the association between self-reported leisure time physical activity and postoperative complications and recovery on a group level.

Materials And Methods: An observational cohort analysis was performed within a randomized controlled trial.

Objective: To determine the effect of a short-term, unsupervised exercise intervention before and after colorectal cancer surgery on self-assessed physical recovery.

Summary Of Background Data: Preoperative exercise interventions could help improve recovery after colorectal cancer surgery and is currently recommended.

Methods: A randomized, parallel, open-label trial in six university or regional hospitals in Sweden.

Objectives: We report results from a subgroup within the ongoing PHYSSURG-C trial with the aim to examine effects of exercise on IGF-1 and IGFBP-3 in patients undergoing colorectal cancer surgery.

Design: Randomised controlled trial.

Setting: A Swedish university hospital.

Introduction: There is a growing interest in physical activity in relation to recovery after surgery. One important aspect of measuring recovery after surgical procedures is postoperative complications. The aim of this study was to determine if there is an association between the preoperative level of habitual physical activity and postoperative complications in patients undergoing elective surgery for colorectal cancer.

Objectives: This study investigates the effects of the core elements of the Swedish model for physical activity on prescription (PAP) by evaluating studies that compared adults who received PAP with adults who did not receive PAP. All participants were adults identified by a healthcare professional as in need of increased physical activity. Primary outcome was level of physical activity.

Background: Surgery for colorectal cancer is associated with a high risk of post-operative adverse events, re-operations and a prolonged post-operative recovery. Previously, the effect of prehabilitation (pre-operative physical activity) has been studied for different types of surgery, including colorectal surgery. However, the trials on colorectal surgery have been of limited methodological quality and size.

Introduction: An increasing interest is seen in the role of preoperative physical activity (PA) in enhancing postoperative recovery. The short-term effect of preoperative PA on recovery after colorectal cancer is unknown. The aim of this study was to evaluate the association of the preoperative level of PA with postoperative recovery after surgery due to colorectal cancer disease.

Regular physical activity (PA) reduces the blood pressure (BP) of individuals with hypertension. The present review analysed the scientific evidence for the BP lowering effect of aerobic PA in 27 randomised controlled studies on individuals with hypertension, and shows that regular medium-to-high-intensity aerobic activity reduces the BP by a mean of 11/5 mm Hg (level of evidence, 3+). In addition, three randomised controlled trials (RCTs) on isometric (static) activity showed a BP reduction of similar magnitude in hypertensives; dynamic resistance training may show less effect, as shown in five available RCTs (level of evidence 2+).
