Skeletal muscle omics signatures in cancer cachexia: perspectives and opportunities.

Cachexia is a life-threatening complication of cancer that occurs in up to 80% of patients with advanced cancer. Cachexia reflects the systemic consequences of cancer and prominently features unintended weight loss and skeletal muscle wasting. Cachexia impairs cancer treatment tolerance, lowers quality of life, and contributes to cancer-related mortality.

Using a Network Physiology Approach to Prescribe Exercise for Exercise Oncology.

Current American College of Sports Medicine (ACSM) exercise guidelines for exercise oncology survivors are generic one-size fits all recommendations, which assume ideal or prototypic health and fitness state in order to prescribe. Individualization is based on the objective evaluation of the patient's baseline physiological status based on a linear dose response relationship of endpoints. This is only a partial snapshot of both the acute and chronic responses exercise can provide.

Background: This study aimed to characterize the types of intraoperative delays during robotic-assisted thoracic surgery, operating room staff awareness/perceptions of delays, and cost impact of delays on overall operative costs.

Methods: Robotic-assisted thoracic surgery cases from May to August 2019 were attended by 3 third-party observers to record intraoperative delays. The postoperative surveys were given to operating room staff to elicit perceived delays.

Implementation of a Postoperative Screening and Treatment Guidance for the Low Anterior Resection Syndrome: Preliminary Results.

Background: Even years after a low anterior resection, many patients experience persisting bowel complaints. This is referred to as low anterior resection syndrome and has a severe adverse effect on quality of life. Its diverse nature makes it difficult to find a gold-standard therapy for this syndrome.

Prehabilitation before major intra-abdominal cancer surgery: A systematic review of randomised controlled trials.

Background: Although prehabilitation programmes for patients undergoing major intra-abdominal cancer surgery have been shown to improve pre-operative physical fitness, the conclusions regarding any postoperative benefits are inconsistent.

Objectives: The aim of this study was to evaluate the content of and the outcome measures used in studies of prehabilitation programmes for these patients. It was hypothesised that the content of prehabilitation programmes is often therapeutically invalid, and that the postoperative outcomes assessed are inadequate to evaluate the impact of complications.

Cancer treatment effects on cognition and depression: The moderating role of physical activity.

Objectives: Breast cancer survivors report significant cognitive impairments post treatment, particularly following chemotherapy. Depression may also occur post treatment and may partially mediate the effects of cancer treatment on cognition. Additionally, physical activity has been shown to mitigate treatment effects on cognition and depression.

Multimodal prehabilitation in colorectal cancer patients to improve functional capacity and reduce postoperative complications: the first international randomized controlled trial for multimodal prehabilitation.

Background: Colorectal cancer (CRC) is the second most prevalent type of cancer in the world. Surgery is the only curative option. However, postoperative complications occur in up to 50% of patients and are associated with higher morbidity and mortality rates, lower health related quality of life (HRQoL) and increased expenditure in health care.

Awareness and management of low anterior resection syndrome: A Dutch national survey among colorectal surgeons and specialized nurses.

Introduction: Substantial progress has been made in the treatment of rectal cancer in the past two decades. Low anterior resection is a cornerstone in current treatment, combined with neo-adjuvant (chemo-) radiation in selected cases. However, side effects such as increased frequency, urgency and incontinence are seen in a majority of patients postoperatively.

The effect of exercise on body composition and bone mineral density in breast cancer survivors taking aromatase inhibitors.

Objective: This study examined the effect of 12 months of aerobic and resistance exercise versus usual care on changes in body composition in postmenopausal breast cancer survivors taking aromatase inhibitors (AIs).

Methods: The Hormones and Physical Exercise study enrolled 121 breast cancer survivors and randomized them to either supervised twice-weekly resistance exercise training and 150 min/wk of aerobic exercise (N = 61) or a usual care (N = 60) group. Dual-energy X-ray absorptiometry scans were conducted at baseline, 6 months, and 12 months to assess changes in body mass index, percent body fat, lean body mass, and bone mineral density.

Effect of exercise on metabolic syndrome variables in breast cancer survivors.

Objective. Breast cancer survivors are highly sedentary, overweight, or obese, which puts them at increased risk for comorbid chronic disease. We examined the prevalence of, and changes in, metabolic syndrome following 6 months of an aerobic exercise versus usual care intervention in a sample of sedentary postmenopausal breast cancer survivors.

Weight Loss Intervention for Breast Cancer Survivors: A Systematic Review.

To determine the effectiveness of weight loss intervention for breast cancer survivors. From October 2012 until March 2013, Pubmed was searched for weight loss intervention trials that reported body weight or weight loss as a primary outcome. Fifteen of these studies are included in this review.

Obesity, growth hormone and exercise.

Growth hormone (GH) is regulated, suppressed and stimulated by numerous physiological stimuli. However, it is believed that obesity disrupts the physiological and pathological factors that regulate, suppress or stimulate GH release. Pulsatile GH has been potently stimulated in healthy subjects by both aerobic and resistance exercise of the right intensity and duration.

Effects of acute resistance exercise on muscle damage and perceptual measures between men who are lean and obese.

The purpose of this investigation was to assess indices of muscle damage and psychological stress between young, untrained, lean, and obese men. Using a between-subject design, 19 young men (9 lean men [age, 20.1 ± 2.

Effect of exercise on markers of inflammation in breast cancer survivors: the Yale exercise and survivorship study.

Physical activity is associated with improved breast cancer survival, but the underlying mechanisms, possibly including modification of the inflammatory state, are not well understood. We analyzed changes in interleukin (IL)-6, C-reactive protein (CRP), and TNF-α in a randomized controlled trial of exercise in postmenopausal breast cancer survivors. Seventy-five women, recruited through the Yale-New Haven Hospital Tumor Registry, were randomized to either a six-month aerobic exercise intervention or usual care.

Effects of resistance exercise and obesity level on ghrelin and cortisol in men.

Immunoreactive and bioactive growth hormone responses to resistance exercise in men who are lean or obese.

It has been suggested that obese individuals have a blunted growth hormone (GH) response to spontaneous and stimulated GH secretion. The present study was designed to examine the effects of a high-volume, whole body acute resistance exercise (RE) protocol on immunoreactive GH (iGH), bioactive GH (bGH), and GH-binding protein (GHBP) in sedentary lean and obese men. Nine obese (mean ± SD: 20.

Growth hormone, exercise, and athletic performance: a continued evolution of complexity.

Growth hormone (hGH) presents pleiotropic effects in many tissues encompassing a diverse range of physiological actions. Its complexity as a family of hormones with different isoforms and different somatotroph molecular functions continues to challenge the status quo of our understanding of its release, function, and signaling. Owing to the fact that the majority of the literature has viewed hGH from the perspective of the primary 22 kD monomer, further investigation is needed as to the influence and biological activity of other aggregate and splice variant isoforms that are released into circulation.
