Gender Differences in Treatment Outcomes for Eating Disorders: A Case-Matched,Retrospective Pre–Post Comparison

Eating disorders (EDs) are increasingly emerging as a health risk in men, yet men remain underrepresented in ED research, including interventional trials. This underrepresentation of men may have facilitated the development of women-centered ED treatments that result in suboptimal outcomes for men. The present study retrospectively compared pre- vs. post-treatment outcomes between age-, diagnosis-, and length-of-treatment-matched samples of n = 200 men and n = 200 women with Anorexia Nervosa (AN), Bulimia Nervosa (BN), Binge Eating Disorder (BED), or Eating Disorder Not Otherwise Specified (EDNOS), treated in the same setting during the same period, and using the same measurements. Compared to women, men with AN showed marked improvements in weight gains during treatment as well as in ED-specific cognitions and general psychopathology. Likewise, men with BED showed marked weight loss during treatment compared to women with BED; ED-specific cognitions and general psychopathology outcomes were comparable in this case. For BN and EDNOS, weight, ED-specific cognitions, and general psychopathology outcomes remained largely comparable between men and women. Implications for treatments are discussed.     

Flexible intramedullary nailing for distal femoral fractures in patients with myopathies

Purpose  

Distal femoral fractures are quite common in nonambulating patients with myopathies, as they present marked osteoporosis. The deterioration of preexisting knee flexion contracture is a known problem, as these fractures are usually angulated posteriorly. The goals of treatment are to reduce immobilization and bed rest to a minimum, prevent function loss, and prevent refracture. The aim of our work was to investigate if these goals can be achieved by an operative treatment with closed reduction and flexible intramedullary nailing (FIN).     

Does Spatial Accessibility of Pharmacy Services Predict Compliance with Long-Term Control Medications?

Background: Disadvantaged urban children with asthma are at high risk for undermanagement of their disease and poor compliance with inhaled corticosteroids (ICS). Objective: To determine whether spatial accessibility (SA) of retail pharmacy services is associated with ICS compliance. Methods: Caregivers of 137 urban high-morbidity asthmatic children attended a comprehensive intervention to improve asthma care and outcomes. Subsequent ICS compliance was determined at 1, 3, and 6 months. We modeled 18 measures of SA to 339 pharmacies using logistic regression and adjusting for numerous covariates. Results: No relationships between SA and compliance were found. Conclusions: In this group of disadvantaged urban children with severe asthma, compliance with ICS was not significantly associated with SA of retail pharmacy services.     

Hypnotic susceptibility modulates brain activity related to experimental placebo analgesia

Identifying personality traits and neural signatures that predict placebo responsiveness is important, both on theoretical and practical grounds. In the present functional magnetic resonance imaging (fMRI) study, we performed multiple-regression interaction analysis to investigate whether hypnotic susceptibility (HS), a cognitive trait referring to the responsiveness to suggestions, explains interindividual differences in the neural mechanisms related to conditioned placebo analgesia in healthy volunteers. HS was not related to the overall strength of placebo analgesia. However, we found several HS-related differences in the patterns of fMRI activity and seed-based functional connectivity that accompanied placebo analgesia. Specifically, in subjects with higher HS, the placebo response was related to increased anticipatory activity in a right dorsolateral prefrontal cortex focus, and to reduced functional connectivity of that focus with brain regions related to emotional and evaluative pain processing (anterior mid-cingulate cortex/medial prefrontal cortex); an opposite pattern of fMRI activity and functional connectivity was found in subjects with lower HS. During pain perception, activity in the regions reflecting attention/arousal (bilateral anterior thalamus/left caudate) and self-related processing (left precuneus and bilateral posterior temporal foci) was negatively related to the strength of the analgesic placebo response in subjects with higher HS, but not in subjects with lower HS. These findings highlight HS influences on brain circuits related to the placebo analgesic effects. More generally, they demonstrate that different neural mechanisms can be involved in placebo responsiveness, depending on individual cognitive traits.
