ABSTRACT
OBJECTIVE: The aim of this review was to determine the effects of epidural analgesia as it relates to outcome after colorectal surgery. METHOD: We searched and reviewed studies that included colorectal surgery and epidural method of analgesia listed on the Pubmed, Medline, Embase and the Cochrane library database. RESULTS: The majority of data demonstrate a superior effect of epidural analgesia on pain control after colorectal surgery. Well designed randomized controlled trials (RCT's) have also shown that epidural analgesia reduces the duration of ileus after colorectal surgery. Limited data suggest the additional benefit may be minimal after laparoscopic surgery or when epidural analgesia is used as part of a multimodal regime. Data does not convincingly show either a clear harmful or beneficial effect of epidural analgesia on rates of anastomotic leakage. Epidural analgesia may have beneficial effects on postoperative lung function, however due to low numbers, the effects on cardiovascular and thromboembolic complications are indeterminate. Length of hospital stay has not been shown to be shortened by sole use of an epidural and, although epidural analgesia may be apparently more costly, alternatives may incur higher indirect costs and decreased patient satisfaction. CONCLUSION: Randomized controlled trials have shown a benefit for epidurals on postoperative pain relief, and ileus, and possibly respiratory complications. There is no proven benefit with regard to length of stay. There are a number of unresolved issues which further focussed RCT's may help clarify such as effects of epidural on complication rates after colorectal surgery.

OBJECTIVE: This study examined the thyroxine (T4) and free T4 (FT4) status of women with bulimia nervosa and its value as a predictor of outcome. METHOD: A total of 135 women with bulimia nervosa underwent 12-weeks cognitive behavioral therapy treatment. Prior to and at 3-year follow-up patients completed psychiatric assessments and serumT4 and FT4 were measured. RESULTS: At 3-year follow-up, 71% had no eating disorder and 29% met criteria for any eating disorder diagnosis. Mean T4 and FT4 concentrations were within normal ranges. Pre-treatment T4 and FT4 concentrations were inversely associated with food restriction and purging frequency, respectively. Compared with women with no eating disorder, those with any eating disorder at follow-up had lower pretreatment T4 concentrations. When pre-treatment food restriction, oral contraceptive use and binge frequency where controlled for, low T4 concentration was the only predictor of eating disorder diagnosis at follow-up. CONCLUSION: Low T4 concentrations at pretreatment may be a predictor of poor outcome in bulimia nervosa.

OBJECTIVE: This community-based study examined how some women who have experienced childhood sexual abuse (CSA) develop an eating disorder (ED), whereas others develop depression and anxiety, and others show no adverse psychological sequelae. METHODS: A two-stage random community sampling strategy was used to select two groups of women: (1) women with CSA prior to age 16 years and (2) a comparison group of women reporting no abuse. Both groups completed the Parental Bonding Instrument (PBI), the Present State Examination, and additional ICD-10 eating disorders questions. Information on the nature and frequency of the CSA was obtained at interview. CSA women with ED (CSA+ED) were compared with CSA women without ED (CSA-noED) and with CSA women with anxiety and/or depression (psychiatric comparison group). RESULTS: Higher rates of EDs in women who have experienced CSA were confirmed in this study. Belonging to a younger age cohort, experiencing menarche at an early age, and high paternal overcontrol on the PBI independently increased the risk of developing an ED in women who had experienced CSA. Low maternal care was specifically associated with the development of anorexia nervosa, whereas early age of menarche differentiated women with bulimia nervosa. Younger age and early age of menarche also differentiated the CSA+ED women from the psychiatric comparison group. DISCUSSION: Early maturation and paternal overcontrol emerged as risk factors for ED development in women with CSA. Although these variables are also risk factors in the general population, women with CSA may be vulnerable to ED development because these risk factors are particular domains of concern that emanate from experiences of CSA.

BACKGROUND: The present study investigated the role of serotonin in the pathophysiology of bulimia nervosa (BN) by studying the affective and appetitive responses of women ill with BN to an acute tryptophan depletion (ATD) paradigm. METHODS: Twenty-two women with BN and 16 healthy control women (CW) were studied on 2 separate days during the follicular stage of the menstrual cycle. Participants drank a control mix of essential amino acids (100 g + 4.6 g tryptophan) on one day and a tryptophan deficient (100 g - 4.6 g tryptophan) mixture (ATD) on the other in a double-blind fashion. Mood/appetite ratings and blood samples were taken at baseline and at intervals up to 420 minutes. Participants were then presented with an array of foods and were allowed to binge and vomit if they desired. RESULTS: CW and BN women had a similar and significant reduction in plasma tryptophan levels and the tryptophan: LNAA ratio after ATD. After ATD, the BN women had a significantly greater increase in peak (minus baseline) depression, mood lability, sadness and desire to binge compared to the CW. BN subjects and CW had similar peak changes in mood after the control amino acid mixture. BN subjects and CW consumed similar amounts of food after the two amino acid treatments. CONCLUSIONS: Women with BN seem more vulnerable to the mood lowering effects of ATD, suggesting they have altered modulation of central 5-HT neuronal systems.

This study investigated the effects of meals varying in macronutrient composition on plasma tryptophan/large neutral amino acid (tryp:LNAA) ratios and subsequent appetite and mood in women defined as "food cravers." Nine women consumed one of each of a high protein, high carbohydrate and mixed meal on three separate days. Blood samples and appetite and mood ratings were taken before and at intervals up to 150 min after meal consumption. The first subsequent ad libitum food intake was recorded in diaries. The tryp:LNAA ratio increased significantly after the carbohydrate meal compared to protein and mixed meals. No significant correlations between change in tryp:LNAA ratio and mood or macronutrient intake at the ad libitum eating episode were observed. There was a negative correlation between tryp:LNAA ratio and desire to binge eat (p=0.03) and a trend towards a negative correlation between tryp:LNAA ratio and craving for carbohydrate-rich foods (p=0.07). Participants whose ad libitum eating episode was categorized as a binge had a trend (p=0.06) toward lower plasma tryp:LNAA ratio than those who did not binge. Regression analysis showed that the effects of change in tryp:LNAA ratio on desire to binge eat was independent of meal type and changes in insulin and glucose concentrations. These findings suggest that reducing plasma tryp:LNAA ratio, via consumption of a protein-rich meal, may mediate the desire to binge eat in susceptible women.
ABSTRACT
OBJECTIVES: This study determined the clinical and nutritional variables associated with menstrual disturbance in women with bulimia nervosa (BN). METHODS: Eighty-two women with DSM-IV BN underwent psychiatric, nutritional and menstrual related assessments prior to an outpatient treatment programme and at 12 months follow-up. RESULTS: Forty-five percent reported a current irregular menstrual cycle. A high frequency of vomiting, low thyroxine concentrations and low dietary fat intake were independently associated with irregular menses at pretreatment. At 12 months follow-up, 30.5% reported irregular menstrual cycles. A greater difference between past maximum and minimum body weight, smoking and depression were associated with menstrual irregularity at 12 months follow-up. Of those with irregular menstrual cycles at pretreatment, 56.8% became regular at 12 months follow-up. CONCLUSION: Menstrual irregularity in BN is associated with indices of nutritional restriction that are not reflected by low body weight or energy intake. Depression, cigarette smoking and fluctuations in body weight may act as metabolic stresses that contribute to the perpetuation of menstrual disturbances.

This study investigated the effects of meals differing in macronutrient composition on subsequent food craving, bingeing, nutrient intake, and mood. Nine women who had prospectively demonstrated episodes of craving received one each of a high-protein, high-carbohydrate, and mixed meal on three separate days. Appetite and mood ratings were taken before and at four intervals up to 150 min after meal consumption. Subsequent ad libitum food intake was recorded in diaries. Premeal hunger, appetite and mood ratings were similar across meal type. After the protein-rich meal, craving for sweet, carbohydrate-rich foods was significantly higher than after the carbohydrate and mixed meals. Elevated negative mood state after the protein-rich meal and reduced vigor after the carbohydrate meal were not statistically significant. The first ad libitum eating episodes after the protein meal contained significantly higher absolute and proportional amounts of total carbohydrate and sucrose and were more likely to be categorized as a binge than were those after the carbohydrate and mixed meals. Those ad libitum eating episodes classified as a craving/binge were characterized by a higher energy and absolute carbohydrate, fat, and sucrose content. Evidence of macronutrient compensation after a protein-rich meal suggests that carbohydrate intake regulation may exist in certain individuals. Possibly via the effects of sensory-specific satiety, serotonergic function, or cognitive factors, a protein-rich meal may induce craving for sweet-tasting, palatable foods in susceptible individuals.

BACKGROUND: Disturbances of leptin, neuropeptide Y (NPY), and peptide YY (PYY) have been found in women who are ill with anorexia or bulimia nervosa. It is not certain whether peptide disturbances are cause or consequence of eating disorders. METHODS: Plasma leptin and cerebrospinal fluid leptin, NPY, and PYY concentrations were measured in women who were recovered from anorexia or bulimia nervosa to determine whether alterations persisted after recovery. RESULTS: NPY, PYY, and leptin concentrations were similar across all diagnostic groups. CONCLUSIONS: Alterations in NPY, PYY, and serum leptin concentrations are probably secondary to pathological eating behaviors. Alterations of these peptides are unlikely to be trait-related disturbances that contribute to the etiology of eating disorders.

Serum visceral protein and hematological indices and their behavioral and clinical correlates were determined in women with bulimia nervosa and depressed controls. One hundred and fifty-two women who met DSM-IV criteria for bulimia nervosa and 68 women with DSM-IV major depression completed a structured clinical interview and had blood samples drawn prior to admission to outpatient treatment programs. Albumin and prealbumin concentrations were lower in the depressed women, possibly due to recent weight loss. Elevated transferrin values suggested mild iron deficiency in nearly one-fifth of women with bulimia nervosa. Of women with bulimia nervosa, the 10.7% who had hemoglobin and 5.1% who had vitamin B12 levels below the normal range were not distinguishable on measures of body mass index, binge eating, vomiting, or restriction frequency. The 4.3% with low prealbumin levels experienced significantly more episodes of binge eating and vomiting in the prior fortnight than those with normal values. Frequency of vomiting was also inversely associated with albumin concentration. Hamilton Depression Rating Scale scores were inversely and linearly related to serum vitamin B12. Lower B12 levels in those with alcohol abuse/dependence did not explain the association between B12 and HDRS scores. No hematological indices were related to body mass index, binge eating or restriction frequency, or restriction intensity. In summary, women with bulimia nervosa do not appear to be at greater risk of visceral protein or hematological abnormalities than psychiatric controls. It is suggested that a high frequency of vomiting and alcohol abuse/dependence, increases the risk of subclinical malnutrition in women with bulimia nervosa, and that poor vitamin B12 nutriture may interfere with the functioning of the serotonergic or catecholaminergic systems and contribute to depressive symptoms in bulimia nervosa.

OBJECTIVES: The objectives of this study were to determine: 1) factors associated with body mass index (BMI) in women with bulimia nervosa prior to treatment; 2) changes in BMI during cognitive behavioral therapy (CBT) for bulimia nervosa; and 3) predictors of weight change during CBT treatment. METHODS: Participants were 94 women with DSM-III-R bulimia nervosa enrolled in a randomized clinical trial of CBT. Eating disorder symptomatology, past and current psychopathology, and BMI were measured prior to treatment and after twelve weeks of treatment. RESULTS: A significantly lower BMI prior to treatment was independently associated with a history of anorexia nervosa, substance use, cigarette smoking, and a high frequency of vomiting. Reductions in binge eating, purging, and food restriction after treatment did not result in significant changes in BMI. Increasing age, higher maximum lifetime body weight, and a high frequency of binge eating at baseline predicted weight gain during treatment. Weight loss during treatment was predicted by a high frequency of vomiting, and elevated levels of body dissatisfaction prior to treatment. DISCUSSION: Patients hesitant to engage in treatment for fear of weight gain upon cessation of their bulimic behaviors should be reassured that CBT is not usually accompanied by substantial weight gain. Identification of women at risk of significant weight gain or loss during CBT may enable therapists to focus on its aspects that help to prevent excessive body weight changes.

OBJECTIVE: Given that dietary restraint and associated dietary behavior may predispose individuals to frank eating disorders, and that differences in personality profiles have been observed across subtypes of eating disorders, we sought to address whether aspects of restrained eating (cognitive restraint, disinhibition, and susceptibility to hunger) could be distinguished using the Temperament and Character Inventory (TCI). METHOD: One hundred and one women aged 18-45 selected at random from the community completed the Diagnostic Interview for Genetic Studies (DIGS), the TCI, and the Three Factor Eating Questionnaire (TFEQ). RESULTS: Novelty seeking (NS) was significantly positively correlated with disinhibition. Self-directedness (SD) was negatively correlated with the total TFEQ score, disinhibition, and susceptibility to hunger. Self-transcendence (ST) correlated positively with total TFEQ score and cognitive restraint. DISCUSSION: These findings suggest that individuals with character traits denoting low SD and high ST may be particularly reactive and susceptible to societal messages pertaining to the ideology of slenderness.

OBJECTIVE: Food cravings are a frequently described antecedent to binge eating, yet not all of those who report food cravings also binge eat. The present study sought to determine the factors that distinguish cravers who binge versus those whose cravings are satisfied by a relatively "normal" amount of food. METHOD: A food craving questionnaire, a psychiatric diagnostic interview containing questions on binge eating, and a self-report booklet were completed by a group of cravers recruited by advertisement and a group of cravers from a randomly selected sample. RESULTS: In both groups, the cravers who binged were differentiated from those who did not binge by higher measures of body mass index (BMI), more frequent diagnoses of bulimia nervosa, a higher level of dietary restraint, and a by a temperament characterized by low self-directedness. In the recruited cravers, those who binged were also more likely to have had an episode of major depression, social phobia, to be cognitively controlled and harm avoidant. A comparison of recruited cravers with randomly selected cravers and control women suggests that greater rates of psychopathology and eating-related disturbances and lower levels of parental care may be found in recruited samples. DISCUSSION: In addition to elucidating factors associated with binge eating in cravers, this study highlights important differences between recruited and random samples.

OBJECTIVE: It has been suggested that total serum cholesterol concentrations are elevated in bulimia nervosa. The objectives of this study were to compare cholesterol concentrations in women with bulimia nervosa with those of depressed women and population norms and to determine the dietary correlates of elevated cholesterol concentrations. METHODS: 126 women with bulimia nervosa and 57 women with major depression participating in clinical trials were studied. Total serum cholesterol concentrations were available for all participants. Prospective 2-week dietary intake analysis was examined for 49 of the bulimic women. RESULTS: Bulimic women had markedly higher total cholesterol concentrations than depressed women and in comparison to consensus recommendations and population norms. This finding remained highly statistically significant after taking into account an array of potential physical and psychopathological covariates. Dietary analysis suggested that increased total cholesterol concentrations were related to cholesterol and fat intake during binge eating, but not during normal eating. DISCUSSION: Bulimic women have higher total cholesterol concentrations that are related to excess cholesterol and fat intake during binge eating.

OBJECTIVE: The objective of the present study was to determine the prevalence and characteristics of food cravings in women with a history of anorexia nervosa. METHOD: One hundred one control women selected at random and 64 women with a diagnosis of anorexia nervosa 10 to 14 years earlier (cases) completed the Diagnostic Interview for Genetic Studies, a food craving questionnaire, the Temperament and Character Inventory and the Three-Factor Eating Questionnaire. RESULTS: A similar proportion of cases and controls reported food cravings. A greater proportion of cases reported strong cravings with two or more features of intensity (p = .02). Cravings in the cases were more likely to be characterized by difficulty resisting the craved food (p = .0008), anxiety when the craved food was unavailable (p = .002), and a high frequency of occurrence (p = .001). The cases who craved were significantly more likely to have had lifetime BN (p = .02). CONCLUSION: A similar prevalence of food craving in cases as in controls suggests that successful control of food intake and/or denial of hunger overrides dietary restriction as a precondition for craving in anorexia nervosa. A dysfunction in the serotonergic system, the provision of intermittent reinforcement by binge episodes, and/or frustration due to unsuccessful attempts at dietary restraint may mediate the association of cravings with the presence of lifetime bulimia.

The objective of the present study was to investigate the psychopathology and personality characteristics of women who experience food cravings. A total of 101 young women selected at random from the community completed the Diagnostic Interview for Genetic Studies with a trained interviewer. The interview included a section about food-craving experiences and associated factors. Subjects also completed a self-report questionnaire booklet containing the Temperament and Character Inventory (TCI) and the Eating Disorder Inventory (EDI). Compared to noncravers, women who reported food cravings were significantly more likely to report a history of alcohol abuse/dependence (p = .003), significant weight changes (p = .003), and to have undertaken dieting (p = .02), bingeing (p = .05), vomiting (p = .02), exercise (p = .04), diet pill (p = .03), and laxative use (p = .01) to control weight. There was a trend for the cravers to have higher novelty-seeking scores on the TCI (p = .06). Our findings suggest that women who experience food cravings are more likely to have met criteria for alcohol abuse/dependence and tend to have temperament characterized by higher levels of novelty seeking. In addition the high rates of eating-disorder symptomatology implies overconcern with body weight and shape in the women who experienced food cravings.

OBJECTIVE: The objective of this study was to evaluate the meal patterns and nutrient intake of women with bulimia nervosa (BN), and to compare them to clinical variables and recommended dietary allowances (RDA). METHOD: The nutrient intake of 50 women with BN was analyzed from 14 day dietary records. The data were compared to the median intakes of a random sample of women and to the RDA. Clinical variables for the women with BN were also available. RESULTS: Compared to nonbinge episodes per day, binge eating was significantly higher in energy from sucrose, fat, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA) and lower in protein. Compared to the population median, binge eating was significantly lower in percent energy from protein, and higher in percent carbohydrate (CHO), sucrose, SFA, and MUFA, while nonbinge eating was significantly lower in percent energy from fat, SFA, and MUFA. Total intakes were significantly higher in energy and percent energy sucrose compared to the population. Despite significantly lower nonbinge energy intake, calcium, vitamins A and C, iron, and folate were not significantly different to the population median. However, one half or more of the subjects had less than two-thirds the RDA for nonbinge calcium, iron, zinc and for total intake one fourth remained less than two-thirds the RDA for iron and zinc. CONCLUSION: Nonbinge eating was characterized by low energy intake and by low intake of iron, calcium, and zinc. Binge eating, characterized by high sucrose and SFA content, overcompensated for these low energy intakes. Where treatment reduces or eliminates binge eating, it should also encourage consumption of regular meals and in particular, consumption of foods rich in zinc and iron.

The objective of this study was to determine the characteristics of food cravings in a random sample of young women and to evaluate the impact of the definition used in food craving research. The Diagnostic interview for Genetic Studies and a questionnaire about food craving experiences were completed by 101 women aged between 18 and 45 years. Of this sample, 58% of respondents reported having ever experienced food cravings. Of these, 7% had experienced food cravings only during pregnancy. Fewer women met criteria for craving as the definition narrowed; 28% reported moderate to strong cravings with two features of intensity; 6% reported moderate to strong cravings with three features of intensity and 4% reported strong cravings with three features of intensity. Features of intensity or "core features" were those that related to strength of craving and were difficulty resisting eating, feeling anxious when the craved food was unavailable and a change in speed of consumption. Of strong cravers, 86% experienced at least two core features, compared with 48% of moderate and 10% of mild cravers. These features may aid in defining the craving state and should be taken into consideration in studies on food cravings.

OBJECTIVE: Some authors stratify women with current, normal-weight bulimia nervosa into groups defined by the presence or absence of a past history of anorexia nervosa. Unlike the distinction between current anorexia nervosa with or without bulimic symptoms, fewer studies have investigated the significance of stratifying bulimic women by a past history of anorexia. METHOD: One hundred and fourteen women with bulimia nervosa in a clinical trial were studied via structured clinical interviews covering Axis I and II disorders and measures of personality and symptomatology. Prospective, 14-day dietary analysis was available for a subset of subjects. RESULTS: Bulimic women with a past history of anorexia nervosa were significantly more likely to have a lifetime anxiety disorder, lower current body mass index, increased cooperativeness on the Temperament and Character Inventory, and increased mature and neurotic scores on the Defense Style Questionnaire. These women also reported lower scores on the bulimia subscale of the Eating Disorders Inventory, but these self-report data were not consistent with the numbers of objective binges or reported energy intake. The prevalence of other Axis I disorders, Axis II personality disorders, and bulimic symptomatology was quite similar across groups. CONCLUSIONS: Although bulimic women with a prior history of anorexia nervosa differed in limited respects from those without such a history, the differences were outweighed by the similarities. A past history of anorexia nervosa did not appear to define particularly meaningful subgroups of women with current, normal-weight bulimia nervosa.
