Excessive sedentary time is ubiquitous in Western societies. Previous studies have relied on self-reporting to evaluate the total volume of sedentary time as a prognostic risk factor for mortality and have not examined whether the manner in which sedentary time is accrued (in short or long bouts) carries prognostic relevance.

Short and long sleep duration have been linked with higher rates of comorbid medical and mental health issues, as well as increased mortality. The current study examined the association between sleep duration, mental health problems, and health risk behaviors in a large sample of U.S. Afghanistan/Iraq era veterans.

The aim of this article is to revisit Ferenczi’s Clinical Diary (1932) to investigate the influence he had on Melanie Klein’s work. It starts from the position that insufficient recognition has been given to Ferenczi’s contribution to Klein’s body of work and her professional development. Her analysis with Ferenczi lasted 5 years, a relatively long analysis for the period. It explores his influence in three specific areas: the importance of raw and early emotion in the maternal bond, the importance of freedom and authenticity in the analytic relationship, and finally the use of transference and countertransference feelings. Ferenczi’s ill-fated experiment with mutual analysis will be discussed as it opened up a route to explore the analytic relationship, with important consequences for the future development of psychoanalysis.

The effect of office type on sickness absence among office employees was studied prospectively in 1852 employees working in (1) cell-offices; (2) shared-room offices; (3) small, (4) medium-sized and (5) large open-plan offices; (6) flex-offices and (7) combi-offices. Sick leaves were self-reported two years later as number of (a) short and (b) long (medically certified) sick leave spells as well as © total number of sick leave days. Multivariate logistic regression analysis was used, with adjustment for background factors. A significant excess risk for sickness absence was found only in terms of short sick leave spells in the three open-plan offices. In the gender separate analysis, this remained for women, whereas men had a significantly increased risk in flex-offices. For long sick leave spells, a significantly higher risk was found among women in large open-plan offices and for total number of sick days among men in flex-offices. Practitioner Summary: A prospective study of the office environment’s effect on employees is motivated by the high rates of sick leaves in the workforce. The results indicate differences between office types, depending on the number of people sharing workspace and the opportunity to exert personal control as influenced by the features that define the office types.

Abstract Purpose. The purpose of this study was to test if moderate to vigorous physical activity (MVPA) in less than the recommended ≥10-minute bouts related to weight outcomes. Design. Secondary data analysis. Setting. Random sample from the U.S. civilian noninstitutionalized population included in the National Health and Nutrition Examination Survey (NHANES). Participants. A total of 4511 adults aged 18 to 64 years from the 2003-2006 NHANES. Method. Clinically measured body mass index (BMI) and overweight/obese status were regressed on accelerometer measures of minutes per day in higher-intensity long bouts (≥10 minutes, ≥2020 accelerometer counts per minute [cpm]), higher-intensity short bouts (<10 minutes, ≥2020 cpm), lower-intensity long bouts (≥10 minutes, 760-2019 cpm), and lower-intensity short bouts (<10 minutes, 760-2019 cpm). Socioeconomic and demographic characteristics were controlled. Results. Both higher-intensity short bouts and long bouts of PA related to lower BMI and risk of overweight/obesity. Neither lower-intensity short bouts nor long bouts related to BMI or risk of overweight/obesity. Conclusion. The current ≥10-minute MVPA bouts guideline was based on health benefits other than weight outcomes. Our findings showed that for weight gain prevention, accumulated higher-intensity PA bouts of <10 minutes are highly beneficial, supporting the public health promotion message that "every minute counts."

Evidence suggests that short and long sleep are associated with a higher risk of type 2 diabetes. Using successive data waves spanning >20 years, we examined whether a change in sleep duration is associated with incident diabetes.

Long bones are far from being simple cylinders, so how is the relative positioning of their various features maintained during growth? A new study shows that growth is isometric and that drift from the correct position is minimized. Read the Research Article.
