Behavioral treatment of obese binge eaters: do they need different care?

This study investigated the relationship between binge eating and the outcome of weight loss treatment. Participants in a 48-week trial of a structured diet combined with exercise and behavior therapy were classified into one of four groups: no overeating; episodic overeating; subthreshold binge-eating disorder(BED); and BED. Binge eating status was not associated with either dropout or adherence to the diet, but did affect weight loss and mood. The BED group lost significantly more weight at the end of treatment than all other groups, even when adjusting for initial weight. At 1-year follow-up, there were no differences among groups in weight loss or weight regain. The BED group began treatment with significantly higher BDI scores, but improvement in mood occurred by week 5. On the basis of these findings, and a review of the recent literature, we conclude that obese binge eaters respond as favorably to standard dietary and behavioral treatments as do obese nonbingers.

Chronic meningoencephalitis associated with Brucella sp. infection in live-stranded striped dolphins (Stenella coeruleoalba).

A chronic, non-suppurative meningoencephalitis was found in three young striped dolphins (Stenella coeruleoalba) during routine neuropathological examination of marine mammals live-stranded on the Scottish coast. In all three dolphins the lesions were associated with the isolation of a Brucella sp. from the brain and with the immunohistochemical detection of brucella antigen. Moreover, antibodies to Brucella spp. were detected in the two dolphins that were subjected to serological examination. Immunohistochemical and serological examinations for morbillivirus antigen and antibodies, respectively, were negative in all cases. Although brucella infection of marine mammals has been extensively documented in recent years, its association with lesions and disease is less well recognized. The present report provides the first description of an association between Brucella sp. infection and neuropathological changes in a cetacean species.

The efficacy of developmentally sensitive interventions and sucrose for relieving procedural pain in very low birth weight neonates.

BACKGROUND: Procedural pain management for very low birth weight (VLBW) neonates has been minimal or nonexistent in most neonatal intensive care units (NICUs). OBJECTIVES: To compare the efficacy of developmentally sensitive behavioral interventions (nonnutritive sucking via a pacifier, positioning) and sucrose for relieving procedural pain in VLBW infants and to determine the influence of contextual factors (gestational age, postnatal age, birth weight, severity of illness, frequency of painful procedures) on pain response. METHOD: In a prospective randomized crossover trial, pain was assessed in 122 VLBW neonates using the Premature Infant Pain Profile following four randomly ordered interventions during consecutive routine heel lance procedures. RESULTS: Significant differences in pain existed among treatment interventions (F = 16.20, p < .0001). The pacifier with sucrose (F = 24.09, p < .0001) and pacifier with sterile water (F = 9.00, p = .003) significantly reduced pain. Prone positioning did not decrease pain (F = 2.24, p = .137). Frequency of painful procedures approached significance in influencing pain response (F = 3.59, p = .01). CONCLUSIONS: The most efficacious interventions for reducing pain from single painful events were the pacifier with sucrose and the pacifier with sterile water. Research on the efficacy and safety of implementing these interventions, alone and in combination, for repeated painful procedures is needed. In addition, research is needed on the influence of implementing these interventions on pain response and clinical outcomes (e.g., health status and neurodevelopmental status) in VLBW neonates in the NICU.

Retrospective exaggeration of symptoms: vomiting after gastric surgery for obesity.

The possibility that patients may retrospectively exaggerate the severity of complaints that they have experienced has not been systematically investigated. The validity of retrospective reports was called into question by a study of vomiting following gastric bypass surgery for obesity. Such vomiting occurred relatively infrequently--no more than 3.4 times per week, even during the first postoperative month. At a 6-month follow-up, however, some patients reported that they had experienced very high rates of vomiting postoperatively, in direct contradiction to their earlier reports. Such retrospective exaggeration has apparently contributed to the widespread belief that vomiting following gastric bypass surgery is a serious problem. We believe that this report is the first to describe retrospective exaggeration of symptoms. Further research is needed to assess the extent of this problem.
