Article Abstract
Objectives: To investigate the relationship between physical activity and prognosis, and the significant factors associated with physical activity in patients with advanced or recurrent lung cancer.
Methods: This retrospective, observational study enrolled 50 outpatients with lung cancer who received chemotherapy. Patients were evaluated for physical function, physical activity (International Physical Activity Questionnaire-Short Form), and nutritional status (Mini Nutritional Assessment-Short Form [MNA-SF]). The relationship between physical activity and prognosis was examined using the log-rank test and Cox proportional hazards model. Multivariate logistic regression analysis was performed to examine factors associated with low physical activity. A receiver operating characteristic curve was used to calculate the MNA-SF cut-off value for low physical activity.
Results: Low physical activity was significantly associated with survival (HR, 4.35; 95% confidence interval [CI], 1.16-16.27; p=0.029). The MNA-SF was a significant factor associated with low physical activity (OR, 0.71; 95% CI, 0.52 to 0.98; p=0.038). The MNA-SF cut-off value for low physical activity was 9.5 points.
Conclusions: Low physical activity may be a prognostic factor in lung cancer, with nutritional status associated with low physical activity. Regular assessments using the MNA-SF cut-off and physical activity interventions considering nutrition are needed in clinical practice.

Department of Cardiorespiratory Physiotherapy and Rehabilitation, Faculty of Physical Therapy and Rehabilitation, Hacettepe University, Ankara, Türkiye.
Background: Vascular changes are observed in children with cystic fibrosis (cwCF), and gender-specific differences may impact arterial stiffness. We aimed to compare arterial stiffness and clinical parameters based on gender in cwCF and to determine the factors affecting arterial stiffness in cwCF.
Methods: Fifty-eight cwCF were included.
Association of problematic internet use with health-related daily habits in adolescents: evidence from a school-based survey.

Department of Pediatrics, Faculty of Medicine, Afyonkarahisar Health Sciences University, Afyonkarahisar, Türkiye.
Background: With the development of technology, easier access to the internet and its excessive use have led to problematic internet use (PIU). The prevalence of PIU and its association with lifestyle behaviors in adolescents have become subjects of increasing academic interest. This study aimed to determine the prevalence of PIU among Turkish high school students and to investigate its association with sleep, physical activity and dietary habits.

Although, in principle, the Lancet article Commission on Medicine, Nazism, and the Holocaust, aims to provide medical students with a moral compass to guide the future of medical practice as a social retaining wall against anti-Semitism, it deals with the Holocaust not from a philosophical point of view, but from a pedagogical one, resorting to didactic strategies from a historiographical approach. What seemed to be a plea against the behaviour of the Nazi doctors' experiments becomes a justification of the positive law of the liberal democracies in use. However, what it ignores is of the utmost importance: that the majority of the regime's doctors were tried and sentenced for their iniquitous actions, and yet, in contemporary Western society, an even greater danger is very much present: techno-science, which, as it stands, can once again compromise the identity, dignity and very life of the human person.

Reward delays are often associated with reduced probability of reward, although standard assessments of delay discounting do not specify degree of reward certainty. Thus, the extent to which estimates of delay discounting are influenced by uncontrolled variance in perceived reward certainty remains unclear. Here we examine 370 participants who were randomly assigned to complete a delay discounting task when reward certainty was either unspecified (n=184) or specified as 100% (n = 186) in the task trials and task instructions.

Knowledge tracing can reveal students' level of knowledge in relation to their learning performance. Recently, plenty of machine learning algorithms have been proposed to exploit to implement knowledge tracing and have achieved promising outcomes. However, most of the previous approaches were unable to cope with long sequence time-series prediction, which is more valuable than short sequence prediction that is extensively utilized in current knowledge-tracing studies.
