Eating patterns and unhealthy weight control behaviors are associated with loss-of-control eating following bariatric surgery

BackgroundLoss-of-control (LOC) eating is associated with poor weight-loss outcomes following bariatric surgery. It is not clear whether eating patterns (e.g., total number of daily meals/snacks, eating after suppertime, eating when not hungry) and unhealthy weight control behaviors (e.g., smoking, using laxatives) are associated with or predictive of LOC eating.ObjectivesTo examine whether eating patterns and unhealthy weight-control behaviors are associated with LOC eating and, if so, whether they predict LOC eating in bariatric patients.SettingMulticenter study, United States.MethodsThis is a secondary analysis of the Longitudinal Assessment of Bariatric Surgery–2 study. Assessments were conducted before surgery and at 12, 24, 36, 48, 60, and 84 months after surgery. Logistic mixed models were used to examine the longitudinal associations between eating patterns, unhealthy weight-control behaviors, and LOC eating. Time-lag techniques were applied to examine whether the associated patterns and behaviors predict LOC eating.ResultsThe participants (n = 1477) were mostly women (80%), white (86.9%), and married (62.5%). At the time of surgery, the mean age was 45.4 ± 11.0 years and the mean body mass index was 47.8 ± 7.5 kg/m². The total number of daily meals/snacks, food intake after suppertime, eating when not hungry, eating when feeling full, and use of any unhealthy weight-control behaviors were positively associated with LOC eating (P < .05). Food intake after suppertime, eating when not hungry, and eating when feeling full predicted LOC eating (P < .05).ConclusionMeal patterns and unhealthy weight control behaviors may be important intervention targets for addressing LOC eating after bariatric surgery.     

支气管动脉灌注化疗治疗晚期原发性肺癌近期疗效影响因素分析

目的探讨经支气管动脉灌注化疗(BAI)治疗晚期肺癌近期疗效的影响因素。方法回顾性分析1990年3月至2006年6月间胸部X线片复查资料相对完整的82例经BAI治疗的原发性晚期肺癌的近期疗效。结果完全有效(CR)10例(12.2%)、部分有效(PR)32例(39.0%)、轻微有效(MR)23例(28.0%)、稳定(SD)15例(18.3%)、进展(PD)2例(2.4%)。单因素方差分析结果显示,半月时肿瘤缩小率(TDR1/2month)(χ2=25.92,P<0.01)、BAI次数(TBAI)(χ2=17.70,P<0.01)、肿瘤大小(Tsize)(χ2=14.21,P<0.01)和肿瘤血供丰富程度(χ2=6.59,P<0.01)对近期疗效的影响具有统计学意义。对年龄、病理类型等12项协变量进行二项分类Logistic回归分析,采用向后删除法经10步二次迭代,得到Logistic回归方程:P(1)=1/[1 e-(-8.953 2.656TDR1/2month 1.382TBAI 1.230Tsize)],方程对BAI近期疗效有效与无效的预测正确率分别为85.7%和70.0%。结论第1次BAI后半月时的肿瘤缩小率、BAI治疗次数和肿瘤的大小是影响BAI近期疗效的因素。

Parieto-occipital hypoperfusion in late whiplash syndrome: first quantitative SPET study using technetium-99m bicisate (ECD)

Brain single-photon emission tomography (SPET) withN,N-1,2-ethylene-diylbis-l-cysteine diethyl ester dihydrochloride (ECD) was performed on ten patients with a clinically high grade late whiplash syndrome and on 11 controls. Two independent readers blinded to the clinical diagnosis were able to separate the ten patients from normal controls. All these patients had qualitative bilateral parieto-occipital hypoperfusion. To confirm this, the perfusion rate of parieto-occipital over global (perfusion index) was calculated after drawing elliptical regions of interest in transversal-oblique slices. The perfusion indices in patients were significantly lower than in controls as tested by the Mann-WhitneyU test. This quantitative study proves our recent qualitatively analysed observation (Lancet 1995; 345: 1513–1514).     

Patterns of the coronary artery irrigation in the left ventricle

Summary Nowadays, the classifications of coronary arterial preponderance (Schlesinger, Baroldi, Gensini) do not provide the necessary information for a good systematization of coronary arterial irrigation. Based on segmental analysis (Selvester's method) an alternative classification of the arterial distribution of the left ventricle is presented. One thousand eighty ventricle segments corresponding to 90 human hearts (age range from 4 days to 94 years) are studied, using microdissection techniques. In order to obtain segmental arterial patterns, a cluster analysis was used. The alternative classification is based on the predominance of the segments irrigated by: the anterior interventricular artery (Type I; 31% of cases), the circumflex artery (Type II; 37% of cases), or a balance between both arteries (Type III; 32% of cases). Each group can be divided into two subgroups (A and B), according to the existence or not of a balance between the territories of anterior interventricular and circumflex arteries. This classification allows as a more realistic approach to the subject of arterial dominance, given that the left ventricle always presents a predominant irrigation from the anterior interventricular, the circumflex or both arteries.

Essai de classification de l'irrigation artérielle coronaire du ventricule gauche

Résumé La classification en dominance artérielle coronaire, actuellement utilisée (Schlesinger, Baroldi, Gensini) ne donne pas toutes les informations nécessaires à une bonne systématisation de la distribution des artères coronaires. Nous présentons ici une classification alternative, basée sur la segmentation des parois du ventricule gauche à la manière de Selvester. 1080 segments ventriculaires gauches de 90 coeurs humains prélevés sur des sujets de 4 jours à 94 ans ont été analysés en utilisant les techniques de microdissection. La présente classification est basée sur — la prédominance de segments irrigués par l'artère interventriculaire antérieure (IVA) : type I, par l'artère circonflexe (CX) : type II, — ou sur l'existence d'un équilibre entre ces deux artères : type III. Le pourcentage de distribution de ces groupes est le suivant : type I : 31 % ; type II : 37 % ; type III : 32 %. Chacun de ces groupes peut-être divisé en deux sous-groupes A et B selon — la prédominance du nombre de segments irrigués exclusivement ou en partage par l'IVA, — ou l'existence d'un équilibre entre l'IVA et la CX. Cette classification permet une approche plus réaliste du problème de dominance artérielle, étant donné que le ventricule gauche est toujours irrigué en prédominance par l'IVA, par la CX ou à la fois par les deux.
