Unlabelled: INTRODUCTION The measurement of the maximal oxygen uptake as a parameter of cardiorespiratory fitness is useful in exercise prescription in functional restoration programs but this measurement requires the subject's maximal exertion which is not always possible in patients with chronic low back pain. The purpose of this study was to develop a regression equation to predict maximal oxygen uptake based on non-exercise data in adult patients with chronic low back pain.
Methods: Cross sectional study in which 70 participants completed a maximal graded exercise test in cycle ergometer to assess maximal oxygen uptake.
Results: Patients achieved a mean +/- SD value of VO(2)max of 30.8 (+/-7.7) ml kg(-1) min(-1). The regression model included as data of non-exercise the patient's gender, body mass index and the intensity of physical activity during leisure time. Multiple linear regression analysis generated the following formula (R (2) = 38.3, SEE = 6.08 ml kg(-1) min(-1)): VO(2)max (ml kg(-1) min(-1)) = 35.3377 - 0.475411 x BMI + 0.155232 x PALT + 7.97682 x gender; where BMI = body mass index, PALT = physical activity during leisure time, women = 0, men = 1. The Durbin Watson statistic showed no problems with serial autocorrelation (D-W = 1.86). The Kolmogorov-Smirnov normality test demonstrated that the errors are distributed normally.
Conclusions: This study provides a new and relatively precise non-exercise regression model to predict VO(2)max in patients with chronic low back pain.

Background: Opioid medications are important for pain management, but many patients progress to unsafe medication use. With few personalized and accessible behavioral treatment options to reduce potential opioid-related harm, new and innovative patient-centered approaches are urgently needed to fill this gap.
Objective: This study involved the first phase of co-designing a digital brief intervention to reduce the risk of opioid-related harm by investigating the lived experience of chronic noncancer pain (CNCP) in treatment-seeking patients, with a particular focus on opioid therapy experiences.

Cardiovascular and cardiometabolic diseases are leading causes of morbidity and mortality worldwide, driven in part by chronic inflammation. Emerging research suggests that the bone marrow microenvironment, or marrow niche, plays a critical role in both immune system regulation and disease progression. The bone marrow niche is essential for maintaining hematopoietic stem cells (HSCs) and orchestrating hematopoiesis.

Hepatitis B virus (HBV) X protein (HBx) is a key factor for regulating viral transcription and replication. We recently characterized homeobox protein MSX-1 (MSX1) as a host restriction factor that inhibits HBV gene expression and genome replication by directly binding to HBV enhancer II/core promoter (EnII/Cp) and suppressing its promoter and enhancer activities. Notably, HBx expression was observed to be repressed more drastically by MSX1 compared to other viral antigens.
