Abstract

Objectives

The purpose of the present study was to evaluate medical, demographic, and psychosocial correlates of exercise in colorectal cancer survivors (CRC-S) using self-determination theory (SDT).

Methods

Participants were 414 CRC-S who completed a mailed survey that assessed self-reported exercise, medical and demographic variables, and SDT constructs consisting of behavioral regulation for exercise, psychological needs satisfaction in exercise (PNSE), and perceived autonomy support (PAS).

Results

CRC-S with less education were significantly less likely to meet exercise guidelines (21 vs 31%; p < 0.001). Path analysis indicated that SDT and education explained 16% of the variance in exercise behavior with identified regulation (β = 0.17, p = 0.031), introjected regulation (β = 0.14, p = 0.006), and education (β = 0.16, p < 0.001) each making a significant independent contribution.

Conclusions

Few medical and demographic factors are correlates of regular exercise in CRC-S, but SDT provided a good understanding of exercise behavior in this population. Exercise behavior change interventions incorporating principles of SDT may have utility for promoting exercise and improving outcomes in this important population of cancer survivors.

„Überwältigende“ Evidenz für Tripeltherapie beim metastasierten Prostata-Ca.

22.05.2024 Prostatakarzinom Nachrichten

Patienten mit metastasiertem hormonsensitivem Prostatakarzinom sollten nicht mehr mit einer alleinigen Androgendeprivationstherapie (ADT) behandelt werden, mahnt ein US-Team nach Sichtung der aktuellen Datenlage. Mit einer Tripeltherapie haben die Betroffenen offenbar die besten Überlebenschancen.

So sicher sind Tattoos: Neue Daten zur Risikobewertung

Das größte medizinische Problem bei Tattoos bleiben allergische Reaktionen. Melanome werden dadurch offensichtlich nicht gefördert, die Farbpigmente könnten aber andere Tumoren begünstigen.

CAR-M-Zellen: Warten auf das große Fressen

Auch myeloide Immunzellen lassen sich mit chimären Antigenrezeptoren gegen Tumoren ausstatten. Solche CAR-Fresszell-Therapien werden jetzt für solide Tumoren entwickelt. Künftig soll dieser Prozess nicht mehr ex vivo, sondern per mRNA im Körper der Betroffenen erfolgen.

Blutdrucksenkung könnte Uterusmyome verhindern

Frauen mit unbehandelter oder neu auftretender Hypertonie haben ein deutlich erhöhtes Risiko für Uterusmyome. Eine Therapie mit Antihypertensiva geht hingegen mit einer verringerten Inzidenz der gutartigen Tumoren einher.
