A Challenge Called Ogilvie´s Syndrome.

Ogilvie´s syndrome is a colonic dilation without any existing mechanical obstruction. The risk factors that cause it are not completely understood, but if untreated, the distension can result in rupture or ischaemic bowel perforation. Additionally, the existing guidelines do not agree with each other about the next steps if conservative treatment fails.

Associations Between Depressive Symptoms and Physical Activity Intensity in an Older Adult Population During COVID-19 Lockdown.

Introduction: The COVID-19 pandemic led to the implementation of physical-social distancing measures-including self-isolation, home confinement, and quarantine around the world, with psychological consequences such as depression. Older adults are especially likely to develop depressive symptomatology. This study aims to investigate the association between physical activity intensities and sedentary behavior with depression levels among previously active older adults during the COVID-19 lockdown.

Predictors of Lower Depression Levels in Older Adults During COVID-19 Lockdown.

Background: Social distancing during the COVID-19 pandemic may lead to adverse mental health consequences, such as depression, among older adults. This study aimed to investigate the predictors of lower depression scores in older adults living under lockdown.

Methods: 1,123 older Brazilian adults were cross-sectionally assessed for depression, physical activity (PA), pet ownership (dogs, cats, and birds), ability to make video calls, leaving home during lockdown, and not living alone.

Physical Fitness and Health-related Quality of Life in Patients with Colorectal Cancer.

Colorectal cancer is now a frequently treatable illness for most and a chronic disease for many. The number of people living with a diagnosis of colorectal cancer is thus expected to rise. Yet even after successful treatment, colorectal cancer survivors, mostly the elderly, frequently experience health problems and impaired health-related quality of life.

Cardiorespiratory fitness and adiposity in breast cancer survivors: is meeting current physical activity recommendations really enough?

Purpose: Breast cancer (BC) survivors are becoming increasingly predisposed to cardiovascular disease (CVD) mortality. Low cardiorespiratory fitness and physical activity (PA) levels, as well as high values of adiposity indices, contribute to CVD risk. We evaluated adiposity, cardiorespiratory profile, and PA levels in two independent cohorts of BC survivors.

Effects of Exercise on the Immune Function of Pediatric Patients With Solid Tumors: Insights From the PAPEC Randomized Trial.

The purpose of this study was to assess the effects of an in-hospital exercise intervention during neoadjuvant chemotherapy on the inflammatory profile and immune cell subpopulation in 20 children with solid tumors (control [n = 11] and exercise group [n = 9]). Although no significant interaction (group × time) effect was found with an analysis of variance test, we found a trend toward an interaction effect for natural killer cells expressing the immunoglobulin-like receptor KIR2DS4, with their numbers remaining stable in the exercise group but increasing in controls. Our data support that exercise interventions are safe in pediatric cancer patients with solid tumors during chemotherapy treatment despite its aggressive, immunosuppressive nature.

Telomere Length in Elite Athletes.

Unlabelled: Growing evidence suggests that regular moderate-intensity physical activity is associated with an attenuation of leukocyte telomere length (LTL) shortening. However, more controversy exists regarding higher exercise loads such as those imposed by elite-sport participation.

Methods: The authors investigated LTL differences between young elite athletes (n = 61, 54% men, age [mean ± SD] 27.

Cancer Survivor Study (CASUS) on colorectal patients: longitudinal study on physical activity, fitness, nutrition, and its influences on quality of life, disease recurrence, and survival. Rationale and design.

Purpose: Evidence suggests that being physically active in combination with a healthy diet contributes to diminish colorectal cancer risk. However, if this is true for colorectal cancer primary prevention, the same is not clear for its recurrence after colorectal cancer treatments. Data on cancer survival are scarce, and there is a need for greater attention on these survivors' lifestyle behavior.

Exercise Intervention in Pediatric Patients with Solid Tumors: The Physical Activity in Pediatric Cancer Trial.

Introduction: The randomized controlled trial "Physical Activity in Pediatric Cancer" determined the effects of an inhospital exercise intervention combining aerobic and muscle strength training on pediatric cancer patients with solid tumors undergoing neoadjuvant chemotherapy.

Methods: Participants were allocated to an exercise (n = 24, 17 boys; mean ± SEM age, 10 ± 1 yr) or control group (n = 25, 18 boys; 11 ± 1 yr). Training included three sessions per week for 19 ± 2 wk.

Physical Activity and Risk of Coronary Heart Disease and Stroke in Older Adults: The Cardiovascular Health Study.

Background: Although guidelines suggest that older adults engage in regular physical activity (PA) to reduce cardiovascular disease (CVD), surprisingly few studies have evaluated this relationship, especially in those >75 years. In addition, with advancing age the ability to perform some types of PA might decrease, making light-moderate exercise such as walking especially important to meet recommendations.

Methods And Results: Prospective cohort analysis among 4207 US men and women of a mean age of 73 years (standard deviation=6) who were free of CVD at baseline in the Cardiovascular Health Study were followed from 1989 to 1999.

Regular Football Practice Improves Autonomic Cardiac Function in Male Children.

Background: The role of the autonomic nervous system (ANS) in the cardiovascular regulation is of primal importance. Since it has been associated with adverse conditions such as cardiac arrhythmias, sudden death, sleep disorders, hypertension and obesity.

Objectives: The present study aimed to investigate the impact of recreational football practice on the autonomic cardiac function of male children, as measured by heart rate variability.

Physical Activity, Physical Fitness, and Leukocyte Telomere Length: The Cardiovascular Health Study.

Introduction: The influence of physical activity (PA) and physical fitness (PF) at older ages on changes in telomere length (TL)--repetitive DNA sequences that may mark biologic aging--is not well-established. Few prior studies (mainly cross-sectional) have been conducted in older adults, and few studies have evaluated PF.

Methods: We investigated cross-sectional and prospective associations of PA and PF with leukocyte TL among 582 older adults (mean ± SD age, 73 ± 5 yr at baseline) in the Cardiovascular Health Study, with serial TL measures and PA and PF assessed multiple times.

Exercise and risk of major cardiovascular events in adult survivors of childhood hodgkin lymphoma: a report from the childhood cancer survivor study.

Purpose: Survivors of Hodgkin lymphoma (HL) are at increased risk of treatment-related cardiovascular (CV) events; whether exercise modifies this risk is unknown.

Methods: Survivors of HL (n = 1,187; median age, 31.2 years) completed a questionnaire evaluating vigorous-intensity exercise behavior.

Physical activity and heart rate variability in older adults: the Cardiovascular Health Study.

Background: Cardiac mortality and electrophysiological dysfunction both increase with age. Heart rate variability (HRV) provides indices of autonomic function and electrophysiology that are associated with cardiac risk. How habitual physical activity among older adults prospectively relates to HRV, including nonlinear indices of erratic sinus patterns, is not established.

Exercise training can induce cardiac autophagy at end-stage chronic conditions: insights from a graft-versus-host-disease mouse model.

Introduction: Chronic graft-versus-host disease (cGVHD) is a frequent cause of morbimortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and severely compromises patients' physical capacity. Despite the aggressive nature of the disease, aerobic exercise training can positively impact survival as well as clinical and functional parameters. We analyzed potential mechanisms underlying the recently reported cardiac function improvement in an exercise-trained cGVHD murine model receiving lethal total body irradiation and immunosuppressant treatment (Fiuza-Luces et al.

Exercise benefits in chronic graft versus host disease: a murine model study.

Introduction: Chronic graft versus host disease (cGVHD) is a life-threatening complication of allogeneic hematopoietic stem cell transplantation that generates considerable morbidity and compromises the physical capacity of patients. We determined the effects of an exercise training program performed after allogeneic hematopoietic stem cell transplantation on clinical and biological variables in a minor histocompatibility antigen-driven murine model of cGVHD treated with cyclosporine A.

Methods: Recipient BALB/C female mice (age 8 wk) received bone marrow cells and splenocytes from donor B10.

Background: The purpose of this study was to objectively assess pre-school children's total physical activity (TPA) patterns and compliance with guidelines and to examine differences relative to parental education.

Methods: The sample consisted on 509 healthy pre-school children, aged 3-6 years recruited from kindergartens located in the metropolitan area of Porto, Portugal. The PA was assessed for 7 consecutive days by accelerometry.

Relationship of milk intake and physical activity to abdominal obesity among adolescents.

Unlabelled: What is already known about this subject Diet and physical activity (PA) are recognized as important factors to prevent abdominal obesity (AO). Studies have found an inverse relationship between milk intake or milk products and body weight and/or body fat in children and adolescents. Evidence suggests that low levels of PA are associated with AO in youth.

Effects of exercise interventions in graft-versus-host disease models.

Graft-versus-host-disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT), which is associated with high morbimortality and decreased patients' physical capacity. We evaluated the effects of an 11-week moderate-intensity exercise (treadmill) training program performed after allo-HSCT in a murine acute (aGVHD) and chronic GVHD model (cGVHD). Female mice (aged 8-12 weeks) were randomly assigned to the exercise or the control group.

Trans-fatty acid consumption and heart rate variability in 2 separate cohorts of older and younger adults.

Background: Trans-fatty acid (TFA) consumption is associated with risk of coronary heart disease, and trans-18:2, but not trans-18:1, in red blood cell membranes has been associated with sudden cardiac arrest. Abnormal heart rate variability (HRV) reflects autonomic dysfunction and predicts cardiac death. Relationships between TFA consumption and HRV remain understudied.

Influence of body fat and level of physical activity on rate-pressure product at rest in preschool children.

Objective: The rate-pressure product (RPP) has strong correlation with the maximal oxygen consumption and is an indicator of myocardium stress being considered as the best indirect method to measure myocardial oxygen consumption. However, to the best of our knowledge, no studies have addressed in preschool children. The aim of this study was to analyze the influence of percentage of body fat (%BF) and physical activity (PA) patterns on RPP at Rest (RPPrest) as a marker of cardiac load in Preschool children.

Milk intake is inversely related to body mass index and body fat in girls.

Unlabelled: Dairy foods comprise a range of products with varying nutritional content. The intake of dairy products (DPs) has been shown to have beneficial effects on body weight and body fat. This study aimed to examine the independent association between DP intake, body mass index (BMI), and percentage body fat (%BF) in adolescents.
