Objective: Obesity has been associated with chronic inflammation. We hypothesized that body mass index may be inversely related to latency and directly related to infectious complications after preterm premature rupture of membranes.
Study Design: This secondary analysis of a randomized trial of antibiotics for preterm premature rupture of membranes had information available for 562 subjects. We analyzed the association between body mass index and latency, the occurrence of chorioamnionitis, endometritis, and maternal infectious morbidity after controlling for gestational age at rupture and treatment group. Survival analysis, regression, and test of proportions were used as appropriate.
Results: When evaluated as a categorical or continuous variable, body mass index did not reveal any significant associations. Latency to delivery was affected by gestational age at rupture of membrane and antibiotic therapy but not by body mass index group.
Conclusion: Body mass index was not associated with latency or the occurrence of maternal infectious complications during conservative management of premature rupture of membranes before 32 weeks' gestation.

Effects of Ab501 (certolizumab mice equivalent) in arthritis induced bone loss.

Introduction - Rheumatoid arthritis (RA) is a chronic immune-mediated inflammatory disease, which causes local and systemic bone damage. The main goal of this work was to analyze, how treatment intervention with Ab501 (certolizumab mice equivalent) prevents the disturbances on bone structure and mechanics induced by arthritis. Methods - Thirty DBA/1 collagen-induced arthritis (CIA) mice were randomly housed in experimental groups, as follows: arthritic untreated (N=9), preventive intervention (N=10) and treatment intervention (N=11).

Background: Some studies have revealed various sleep patterns in adolescents and adults using multidimensional objective sleep parameters. However, it remains unknown whether these patterns are consistent from adolescence to young adulthood and how they relate to long-term obesity.
Methods: Seven-day accelerometry was conducted in German Infant Study on the influence of Nutrition Intervention PLUS environmental and genetic influences on allergy development (GINIplus) and Influence of Lifestyle factors on the development of the Immune System and Allergies in East and West Germany (LISA) birth cohorts during the 15-year and 20-year follow-ups, respectively.
The present study examined how individuals who have been clinically diagnosed as obese explain their decision to undergo bariatric surgery and how they deal with the stigmatization that such a decision may entail. A total of 23 participants (15 women and 8 men) who were awaiting bariatric surgery within the Spanish healthcare system, were interviewed about their weight trajectory and their decision to undergo this surgery. In order to examine the participants' stories, a narrative analysis of the interviews was conducted, with attention to both content ( they told) and structure ( they told) and examining the stories in line with the socially and culturally available narratives that they had access to, and the context in which the stories were produced.

Objectives: Maternal obesity increases a child's risk of neurodevelopmental impairment. However, little is known about the impact of maternal obesity on fetal brain development.
Methods: We prospectively recruited 20 healthy pregnant women across the range of pre-pregnancy or first-trimester body mass index (BMI) and performed fetal brain magnetic resonance imaging (MRI) of their healthy singleton fetuses.
Validity and normative scores of finger flexor strength and endurance tests estimated from a large sample of female and male climbers.

Recent reviews have highlighted conflicting findings regarding the validity of finger flexor strength and endurance tests in sport climbers, often due to small sample sizes and low ecological validity of the tests used. To address these gaps, 185 male and 122 female climbers underwent maximal finger flexor strength, intermittent and continuous finger flexor endurance, and the finger hang tests in a sport-specific setting to determine the predictive and concurrent validity of these tests. The finger hang test showed the strongest relationship to climbing ability for both sexes ( ≈ 0.
