Radiation therapy increases the risk of secondary malignancy and morbidity in cancer survivors. The role of obesity and exercise training in modulating this risk is not well-understood. As such, we used a preclinical model of radiation-induced malignancy to investigate whether diet-induced obesity and/or endurance exercise training altered life-long survival, cancer incidence, and morbidity.

Male CBA mice were randomly divided into control diet/sedentary group (CTRL/SED), high fat diet (45% fat)/sedentary group (HFD/SED), control diet/exercise group (2-3 days/week; CTRL/EX), or high fat diet/exercise group (HFD/EX) groups, then exposed to whole-body radiation (3 Gy). Endpoint monitoring and pathology determined mortality and cancer incidence, respectively. Healthspan index, a measure of morbidity, was determined by a composite measure of ten anthropometric, metabolic, performance, and behavioral measures.

Overall survival was higher in HFD/SED compared to CTRL/SED (p < 0.05). Risk of cancer-related mortality by 18 months post-radiation was 1.99 and 1.63 in HFD/SED compared to CTRL/EX (RR = 1.99; 95% CI, 1.20-3.31; p = 0.0081) and CTRL/SED (RR = 1.63; 95% CI, 1.06-2.49; p = 0.0250), respectively. The number of mice at endpoint with cancer was higher in HFD/SED compared to CTRL/EX and CTRL/SED (p < 0.05). Healthspan index was highest in CTRL/EX (score = +2.5), followed by HFD/EX (score = +1), and HFD/SED (score = -1) relative to CTRL/SED.

This work provides the basis for future preclinical studies investigating the dose-response relationship between exercise training and late effects of radiation therapy as well as the mechanisms responsible for these effects.

It remains unclear to what extent habitual physical activity and sedentary time are associated with visceral fat and liver fat. We studied substitution of sedentary time with time spent physically active and total body fat (TBF), visceral adipose tissue (VAT) and hepatic triglyceride content (HTGC) in middle-aged men and women.

In this cross-sectional analysis of the Netherlands Epidemiology of Obesity study, physical activity was assessed in 228 participants using a combined accelerometer and heart rate monitor. Total body fat was assessed by the Tanita bio-electrical impedance, VAT by MRI and HTGC by proton-MR spectroscopy. Behavioural intensity distribution was categorized as sedentary time (ST), time spent in light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA). To estimate the effect of replacing 30 minutes/day of ST with 30 minutes/day LPA or MVPA, we performed isotemporal substitution analyses, adjusted for sex, age, ethnicity, education, the Dutch Healthy Diet index, and smoking.

Included participants (41% men) had a mean (SD) age of 56 (6) years and spent 88 (56) minutes in MVPA and 9.0 hours (2.1) of ST. Replacing 30 minutes/day of ST with 30 minutes of MVPA was associated with 1.3% less TBF (95% CI -2.0, -0.7), 7.8 cm2 less VAT (-11.6, -4.0) and 0.89 times HTGC (0.82, 0.97). Replacement with LPA was not associated with TBF (-0.03 %; -0.5, 0.4), VAT (-1.7 cm2; -4.4, 0.9) or HTGC (0.98 times; 0.92, 1.04).

Reallocation of time spent sedentary with time spent in MVPA, but not LPA, was associated with less total body fat, and visceral and liver fat. These findings contribute to the development of more specified guidelines on sedentary time and physical activity.

This study investigated the effects of including sprints within low-intensity training (LIT)-sessions during a 14-d training camp focusing on LIT, followed by 10 days recovery (Rec), on performance and performance-related measures in elite cyclists.

During the camp, a sprint training group (SPR, n = 9) included 12x30-s maximal sprints during five LIT-sessions, whereas a control group (CON, n = 9) performed distance-matched LIT only. Training load was equally increased in both groups by 48 ± 27% during the training camp and subsequently decreased by -56 ± 23% during the recovery period compared to habitual training. Performance tests were conducted before the training camp (Pre) and after Rec. Muscle biopsies, haematological measures and stress/recovery questionnaires were collected Pre and after the camp (Post).

30-s sprint (SPR vs CON 4 ± 4%, p < 0.01) and 5-min mean power (SPR vs CON 4 ± 8%, p = 0.04) changed differently between groups. In muscle, Na+-K+β1 protein content changed differently between groups, decreasing in CON compared to SPR (-8 ± 14%, p = 0.04), while other proteins showed similar changes. SPR and CON displayed similar increases in red blood cell volume (SPR 2.6 ± 4.7%, p = 0.07, CON 3.9 ± 4.5%, p = 0.02) and VO2 at 4 mmol·L-1 [BLa-] (SPR 2.5 ± 3.3%, p = 0.03, CON 2.2 ± 3.0%, p = 0.04). PF543 No changes were seen for VO2max, Wmax, haematological measures, muscle enzyme activity and stress/recovery measures.

Inclusion of 30-s sprints within LIT-sessions during a high-volume training camp affected competition-relevant performance-measures and Na+-K+β1 protein content differently than LIT only, without affecting sport-specific stress/recovery or any other physiological measure in elite cyclists.

It is unknown why some athletes develop patellar tendinopathy and others do not, even when accounting for similar workloads between individuals. Genetic differences between these two populations may be a contributing factor. The purpose of this work was to screen the entire genome for genetic markers associated with patellar tendinopathy.

Genome-wide-association (GWA) analyses were performed utilizing data from the Kaiser Permanente Research Board (KPRB) and the United Kingdom (UK) Biobank. Patellar tendinopathy cases were identified based on electronic health records from KPRB and UK Biobank. Genome-wide association analyses from both cohorts were tested for patellar tendinopathy using a logistic regression model adjusting for sex, height, weight, age, and race/ethnicity using allele counts for single nucleotide polymorphisms (SNPs). The data from the two GWA studies (KPRB abd UK Biobank) were combined in a meta-analysis.

There were a total of 1,670 cases of patellar tendinopathy and 293,866 controls within the two cohorts. Two SNPs located in the intron of the Cytochrome C Oxidase Assembly Factor 1 (COA1) gene showed a genome-wide significant association in the meta-analysis.

Genetic markers in COA1 appear to be associated with patellar tendinopathy and are potential risk factors for patellar tendinopathy that deserve further validation regarding molecular mechanisms.

In normotensive patients with OSA, the muscle sympathetic nerve activity (MSNA) response to exercise is increased while metaboreflex control of MSNA is decreased. We tested the hypotheses that acute intermittent hypercapnic hypoxia (IHH) in males free from OSA and associated comorbidities would augment the MSNA response to exercise but attenuate the change in MSNA during metaboreflex activation.

Thirteen healthy males (age = 24 ± 4 years) were exposed to 40 minutes of IHH. Before and after IHH, the pressor response to exercise was studied during 2-minutes of isometric handgrip exercise (at 30% maximal voluntary contraction) while the metaboreflex was studied during 4-minutes of post exercise circulatory occlusion (PECO). Mean arterial pressure (MAP), heart rate (HR), and fibular MSNA were recorded continuously. MSNA was quantified as burst frequency (BF) and total activity (TA). link2 Mixed effects linear models were used to compare the exercise pressor and metaboreflex before and after IHH.

As expected, IHH ssor reflex and metaboreflex.
A 67-year-old man was referred to our department to undergo a 68Ga-DOTATOC PET/CT during the systematic follow-up of a small intestine neuroendocrine tumor. PET revealed an incidental focal increased uptake of 68Ga-DOTATOC matching with a left intraparotid lesion on the combined contrast-enhanced CT, suggestive of a benign salivary tumor. An MRI was performed to characterize this lesion, and finally, the patient underwent surgery. Histological analysis confirmed the presence of a basal cell adenoma.

Prostate-specific membrane antigen (PSMA) overexpression has been described in various malignancies. Hereby we present a case of a 69-year-old man simultaneously diagnosed with prostate cancer, esophageal adenocarcinoma, and HCC (hepatocellular carcinoma). 18F-FDG PET/CT showed pathological uptake in the esophageal adenocarcinoma and the primary prostate tumor, whereas 68Ga-PSMA-11 PET/CT performed for staging of the histopathologically confirmed prostate cancer revealed the primary tumor and significant uptake in the HCC. This finding is remarkable because the high physiological liver uptake of 68Ga-PSMA-11 may hamper the detection of small lesions.

Different protocols have been suggested to deal with this rare but fatal complication, but their efficacies are rarely reported. We report our institutions' experience in the management of circuit air in Cardiohelp HLS ECMO system. Between October 2009 and July 2020, 4 out of 116 patients developed gas bubbles in ECMO circuit or systemic gas embolism. The clinical characteristics of these patients, source of air, presence of arterial air or pump airlock, cardiorespiratory status during the event, techniques employed to re-establish flow, ECMO downtime, neurologic, and other clinical outcomes were reported. In all cases, the source of air was located, with three of them being on the venous side of the circuit. link3 Centrifugal pump airlock with cessation of ECMO flow was reported in two patients. Strategies used to re-establish ECMO flow included circuit change or deairing using backflush technique. All patients were weaned from ECMO, and three of them were discharged from hospital alive.
