Abstract
Alcohol and Other Drug (AOD) exposure during pregnancy is linked to serious adverse child outcomes, including Fetal Alcohol Spectrum Disorder (FASD). The Parent-Child Assistance Program (PCAP) supports women with problematic AOD use, who are pregnant or have young children, and are not effectively engaging with services. PCAP has been shown to reduce alcohol exposed pregnancies, promote AOD abstinence, increase employment and family planning and improve child outcomes. This manuscript reports the first pilot evaluation of the PCAP program delivered in Australia. A pre-post-intervention repeated measures design was used. Eleven women receiving PCAP from a not-for-profit organisation were invited to take part in the study, with eight providing complete pre-post data. Home visitation case management was provided by trained and experienced case-managers. Clients were assisted to engage with existing services effectively to meet their own goals via a combination of relational theory, motivational interviewing and harm reduction concepts. The PCAP Modified Addiction Severity Index 5th Edition was adapted for use in Australia and was used to measure domains of addiction severity related problems as the primary outcome. Secondary outcomes included client satisfaction and program fidelity. There were significant changes in composite addiction severity scores from baseline to one year. 80% of participants had periods of abstinence of longer than four months. All clients had better connection to services, no subsequent AOD exposed pregnancies, and were highly satisfied with the program. Four had children returned to their care. Implementation was similar to the original PCAP program with major differences including case-managers relying on training manuals only without undertaking in-person training; being more experienced; providing more direct AOD counselling; and having less supervision. The findings will inform future program delivery and methodology for a larger longitudinal study assessing outcomes at program exit.

Abstract
OBJECTIVES We estimated the proportion of people reported with HIV in New Zealand between 2006 and 2017, and alive in 2017-2019, who were on antiretroviral therapy (ART) and had a suppressed viral load (VL), and explored their associated characteristics. METHODS Data were anonymously linked to information on ART and VL within the data collection period (January 2017 to August 2019) using the National Health Index (NHI), Ministry of Health and laboratory datasets, as well as information from clinical specialists. Logistic regression was used to test for associations. Sensitivity analyses were undertaken to estimate the range for the key proportions. RESULTS Overall, 2355 people were reported with HIV, of whom 116 (5%) had died, 337 (14%) were overseas, and 1701 (72%) were alive in New Zealand; for the remaining 201 (9%) the outcome was unknown. Clinical data were available for 1490 people (87.6%): 1408 (94.5%) were on ART, 11 (< 1%) were not on ART, and for 71 (4.8%) this was unknown. Of those on ART, 1156 (82.1%) had a suppressed VL (< 200 copies/mL), 34 (2.4%) were unsuppressed, and for 218 (15.5%) this was unknown. The estimate of the proportion on ART ranged from 99% to 78%, and those with a suppressed VL ranged from 98% to 78%. CONCLUSIONS Among people with HIV in New Zealand who are under care, a high proportion were on ART and had suppressed VL. Increasing collection of NHIs and better linkage with laboratory information will reduce the number with unknown information and provide more complete VL results in the future.

Abstract
Abstract
Introduction
Studies suggest that family intervention programs should consider different sources of parenting stress (PS). Knowing that child sleep has an impact on PS, this study aimed to examine if a child sleep intervention can affect PS in vulnerable families.
Methods
In a first study, parent and child sleep habits along with PS were assessed using Parenting Stress Index-Short Form, Pittsburgh Sleep Quality Index and homemade questions assessing child sleep. Measures were administered to 138 community mothers (children 3-79 months). Multiple linear regression analyses examined mothers and child sleep associations to PS, controlled by family income. Following results of this first study, 11 vulnerable mothers (children 39-68 months) participated in a child sleep intervention specifically developed for vulnerable families. Measures administered were the same as for study 1, but in this study, the Child Sleep Habits Questionnaire was used to assess the child sleep. Wilcoxon’s t-test compared pre and post-intervention measures.
Results
In the first study, sleep onset latency (SOL; β= -.25; p= .003), waketime (β= -.28; p= .003) and sleep aids (β= -.19; p= .048) explained 23.6% of PS variance. When child sleep variables were added to the model, only bedtime resistance was significant (β= -.23; p= .023) and increased the explained variance to 30.6%. Following the child sleep intervention, no significant changes in parent sleep were observed. However, results show improvement of child bedtime resistance (Mpre=10.73; Mpost=8.36; p= .027) and PS (Mpre=3.50; Mpost=3.82; p= .05).
Conclusion
Our results suggest that higher PS is explained by greater struggles in parents sleep (higher SOL, later waketime and higher use of sleep aids) as well as bedtime resistance behaviors in children. Furthermore, PS can be reduced by an intervention improving child bedtime resistance, even if parent sleep is not improved.

Abstract
BACKGROUND We compared Kaposi sarcoma (KS) risk in adults who started antiretroviral therapy (ART) across the Asia-Pacific, South Africa, Europe, Latin, and North America. METHODS We included cohort data of human immunodeficiency virus (HIV)-positive adults who started ART after 1995 within the framework of 2 large collaborations of observational HIV cohorts. We present incidence rates and adjusted hazard ratios (aHRs). RESULTS We included 208140 patients from 57 countries. Over a period of 1066572 person-years, 2046 KS cases were diagnosed. KS incidence rates per 100000 person-years were 52 in the Asia-Pacific and ranged between 180 and 280 in the other regions. KS risk was 5 times higher in South African women (aHR, 4.56; 95% confidence intervals [CI], 2.73-7.62) than in their European counterparts, and 2 times higher in South African men (2.21; 1.34-3.63). In Europe, Latin, and North America KS risk was 6 times higher in men who have sex with men (aHR, 5.95; 95% CI, 5.09-6.96) than in women. Comparing patients with current CD4 cell counts ≥700 cells/µL with those whose counts were <50 cells/µL, the KS risk was halved in South Africa (aHR, 0.53; 95% CI, .17-1.63) but reduced by ≥95% in other regions. CONCLUSIONS Despite important ART-related declines in KS incidence, men and women in South Africa and men who have sex with men remain at increased KS risk, likely due to high human herpesvirus 8 coinfection rates. Early ART initiation and maintenance of high CD4 cell counts are essential to further reducing KS incidence worldwide, but additional measures might be needed, especially in Southern Africa.

Abstract
According to the hologenome theory, the microbiota contributes to the fitness of the holobiont having an important role in its adaptation, survival, development, health, and evolution. Environmental stress also affects the microbiota and its capability to assist the holobiont in coping with stress factors. Here, we analyzed the diversity of cultivable bacteria associated with Manila clam tissues (mantle, gills, hemolymph) in two non-contaminated sites (Portugal and France) and one metal-contaminated site (Portugal). A total of 240 isolates were obtained. Representative isolates (n = 198) of the overall diversity were identified by 16S rDNA sequencing and subjected to functional characterization. Isolates affiliated with Proteobacteria, Actinobacteria, Firmicutes, and Bacteroidetes. Proteobacteria (mostly Pseudoalteromonadaceae and Vibrionaceae) were dominant in non-contaminated sites while Actinobacteria (mostly Microbacteriaceae) dominated in the metal-contaminated site. The main factor affecting the microbiota composition was contamination. No significant differences were observed between clam tissues and geographic regions. Several isolates tested positive for antibacterial activity, biofilm formation, protease, and siderophore production. The results show that the Manila clam harbors a diverse microbiota that may contribute to clam protection and overall fitness, as well as to its adaptation to stressful environments. In addition, the Manila clam microbiota is revealed as a promising source of novel probiotics with potential application in aquaculture.

Abstract
Marine invertebrate microbiota has a key function in host physiology and health. To date, knowledge about bivalve microbiota is poorly documented except public health concerns. This study used a molecular approach to characterize the microbiota associated with the bivalve Manila clam (Ruditapes philippinarum) by determining (1) the difference among organs either or not under the influence of host habitat, (2) small-scale variability of microbiota, and (3) the experimental response of the Manila clam microbiota submitted to different lateral transmissions. These questions were investigated by sampling two groups of individuals living in contrasting habitats and carrying out a transplant experiment. Manila clam microbiota (i.e., bacterial community structure) was determined at organ-scale (gills, gut, and a pool of remaining tissues) by capillary electrophoresis DNA fingerprinting (CE fingerprinting). The Manila clam microbiota structure differed among organs indicating a selection of Manila clam microbiota at organ scale. Habitat strongly influenced gill and gut microbiota. In contrast, microbiota associated with remaining tissues was similar between group individuals suggesting that these communities are mostly autochthonous, i.e., Manila clam specific. Transplant experiment showed that improving living condition did not induce any change in microbiota associated with remaining tissues. In contrast, the reduction in individual habitat quality led to individuals in declining health as strongly suggested by the increase in phagocytosis activity and decrease in condition index together with the change in internal organ microbiota. This study provides a first description of the Manila clam holobiont which can withstand disturbance and respond opportunistically to improved environmental conditions.

Abstract
This research explored the sensory characteristics and consumer acceptance of novel probiotic unsweetened yogurts. Yogurts were made with 4 carrot juice levels (8, 16, 24, and 32%), 2 firmness levels (regular, 45g/L milk solids; firm, 90g/L milk solids), and 2 starter cultures (C1, C2). The sensory profile characterized the color intensity (before and after stirring), carrot flavor, sourness, and 7 texture/mouth-feel attributes (astringency, chalkiness, mouth-coating, thickness, smoothness, creaminess, and graininess). The influence of carrot juice level and firmness level were evaluated using ANOVA, polynomial contrasts, and principal component analysis. Mean scores and standard errors were calculated. Consumer acceptance panels in Wolfville, Nova Scotia (n=56), and in Vancouver, British Columbia (Asian n=72, non-Asian n=72), evaluated the hedonic responses to the C1 and C2 formulations, respectively. We observed increases in color intensity, carrot flavor, creaminess, mouth-coating, and chalkiness with increasing carrot juice levels, as well as increases in color intensity, carrot flavor, creaminess, mouth-coating, thickness, and astringency with increasing milk solids concentrations of the C1 and C2 yogurts. Mean hedonic scores for color, appearance, and texture/mouth-feel were greater than hedonic scores for aroma, flavor/taste, and overall liking. This research identified the sensory qualities that need further development and demonstrated the importance of early-stage consumer acceptance research for directing new product development.

Abstract
The bacterial communities associated with the cockle (Cerastoderma edule) were investigated at the individual level through a 10-month monitoring programme. Temporal changes and those changes associated with a common parasite of the cockle, Bucephalus minimus, were investigated by monthly sampling of individuals, selected based on their shell length (cohort monitoring). Cockle bacterial community abundance (CBCA) and diversity (CBCD) were estimated by epifluorescence microscopy counts and automated ribosomal intergenic spacer analysis, respectively. CBCA showed a temporal pattern peaking at 30 × 10(6) cells per gram of cockle flesh and intervalval liquid in October and a significant 1.8-fold increase linked with B. minimus occurrence. CBCD was characterized by 112 ± 26 intergenic transcribed spacer (ITS) per individual and showed a relative homology between individuals (52 ± 6%, Jaccard similarity) in spite of more than 30% of rare ITS. Consistent with an undisturbed evolution of the condition index of the studied cohort individuals as an estimate of their physiological state, neither temporal nor parasite-induced change in CBCA has been related to marked changes in CBCD.

Abstract
There is uncertainty whether the 2009 seasonal influenza vaccination influences the risk of infection with the 2009 pandemic influenza A(H1N1) virus. This issue was investigated in 548 healthcare workers from Capital and Coast District Health Board, Wellington, New Zealand, presenting with influenza-like illness during the influenza pandemic between June and August 2009. All workers completed an assessment sheet and had a nasopharyngeal swab tested by real-time RT-PCR. The risk of pandemic influenza A(H1N1) infection associated with the 2009 seasonal inactivated trivalent influenza vaccine was determined by logistic regression, with adjustment for potential confounding variables. In 96 workers pandemic influenza A(H1N1) RNA was detected and 452 tested negative. The multivariate analysis did not show any effect of vaccination on PCR-confirmed influenza A(H1N1)2009 infection (odds ratio 1.2, 95% confidence interval 0.7–1.9, p=0.48). We conclude that 2009 seasonal influenza vaccination had no protective effect against influenza A(H1N1)2009 infection amongst healthcare workers. To protect against further waves of the current pandemic influenza or future pandemics in which the influenza virus is antigenically distinct from contemporary seasonal influenza viruses, it would be necessary to vaccinate with a specific pandemic influenza vaccine, or a seasonal influenza vaccine that includes the pandemic influenza serotype.

Abstract
In natural environment, marine organisms are concomitantly exposed to pollutants and multiple disease agents resulting in detrimental interactions. The present study evaluated interactive effects of metal contamination (cadmium) and pathogenic organisms (trematode parasites Himasthla elongata and pathogenic bacteria Vibrio tapetis) singularly and in combination on the bivalve Ruditapes philippinarum, an introduced species to Europe, under laboratory controlled conditions. After 7 days, metal bioaccumulation and pathogen load were analyzed as well as metallothionein (MT) response and hemocyte concentrations and activities. Results showed that infection by opportunistic pathogens affects metal accumulation, leading to maximal Cd accumulation in co-infected clams. Among stressors only V. tapetis induced significant effects on immune parameters whereas a particular interaction "trematode-bacteria" was shown on MT responses. Despite low trematode infection in agreement with the resistant status of R. philippinarum to these macroparasites, significant interaction with bacteria and metal occurred. Such results highlight the necessity of taking pathogens into account in ecotoxicological studies.

Abstract
This study investigated some stress (metals, parasites) and response (immunity, metallothionein) factors in two cockle and two Manila clam populations. Data from eight seasons were averaged to obtain global baseline values. Stress/response characteristics of each population were compared to population health status that was determined through population dynamics parameters. Four different scenarios were discussed: (1) a lightly stressed cockle population with correct population health but with a risk of deterioration (hot spot); (2) a lightly stressed introduced cockle population threatened of extinction. In this case ecological factors were suspected; (3) a moderately stressed clam population with moderate adaptative response. The population was sustainable but the level of stress should not increase (hotspot); and (4) a stressed clam population and unfavourable ecological conditions preventing clam settlement. This monitoring highlighted that the discrepancy between population health and stress levels could be due to insufficient response by bivalves and/or by unfavourable ecological factors.

Abstract
The present study evaluated the interactive effects of cadmium contamination and pathogenic organisms (trematodes Himasthla elongata and bacteria Vibrio tapetis) singularly and in combination during 7 days on the bivalve Cerastoderma edule. Some defense-related activities were analyzed such as genetic expression, metallothionein and immune responses. Trematode metacercarial infection, similar whatever the treatment, induced the strongest responses of immune parameters. Particularly, the interaction between cadmium and parasite exposures induced unusual responses on gene expression and immune responses. No effect of bacterial challenge appeared on bivalve responses, nevertheless a strong mortality of V. tapetis infected cockles occurred between 7 and 14 days. Cadmium bioaccumulation was significantly modulated by both pathogenic organisms. Furthermore, an antagonistic effect of trematodes and bacteria was shown on metal bioaccumulation of co-infected cockles. These results highlighted the importance of considering the multiplicity of perturbation sources in coastal ecosystems to assess the health status of organisms.

Abstract
BACKGROUND There is a belief that peritoneal dialysis may be an important treatment modality for refractory heart failure, allowing at least an improvement in quality if not quantity of life during the last stage of this debilitating chronic disease. This paper examines the rationale behind this modality, critically appraises the available literature, calls for more research in the area and puts forward a framework for considering peritoneal dialysis in refractory heart failure. CONCLUSION When faced with a patient with refractory heart failure admitted to hospital on multiple occasions because of complications of volume overload, the following approach to initiating peritoneal dialysis should be considered: subjects for dialysis must have a minimal blood pressure, and those whose hemodynamic status improves with diuresis, even though they develop a pre-renal picture, may be the best candidates.

Abstract
BACKGROUND This retrospective cohort study investigates the feasibility of using established methods and routinely generated data from the statutory primary school health-screening programme to estimate prevalence rates for childhood overweight and obesity in children from a rural area in the Republic of Ireland (ROI). METHOD Paper-based records in the primary school health service for County Leitrim and parts of County Cavan in north-west of ROI were hand searched to identify children attending senior infant classes during academic year 2001/2002. Electronic calculation of body mass index (BMI) and age at examination was carried out. Application of age- and sex-specific cut-off points from International Obesity Task Force (IOTF) and United Kingdom (UK) standard definitions for childhood overweight and obesity was used to determine age- and sex-specific prevalence rates for childhood overweight and obesity. RESULTS The eligible cohort was almost completely identified and consisted of 361 children. Weight and height measurements were available on 328 (91%) children aged between 4.22 and 7.92 years. IOTF standard application gave prevalence rates of 25% for obesity and overweight in boys and 26% in girls. With the UK growth standard, this increased to 34% in boys and reduced to 23% in girls. CONCLUSION It is feasible to generate prevalence rates for childhood overweight and obesity from data routinely obtained through the statutory school health-screening programme in ROI. This study suggests levels of childhood overweight and obesity comparable to other Western societies. Further research on developing a universally accepted standard definition of childhood overweight and obesity is required.

Abstract
The association between immobility with prolonged sitting and venous thromboembolism has been recognised for > 60 yrs, most recently with long distance air travel. The case of a 32-yr-old male, in whom immobility associated with sitting for long periods at a computer represented the major provoking risk factor for his life-threatening venous thromboembolism, is presented. The authors propose the term "eThrombosis" to describe this 21st Century variant of venous thromboembolism associated with immobility from prolonged sitting. In view of the widespread use of computers in relation to work, recreation and personal communication, the potential burden of eThrombosis may be considerable.

Abstract
Strain Sphingomonassp. (2MPII), isolated from marine sediment, was able to utilize phenanthrene (P) or 2-methylphenanthrene (2MP) as the sole carbon source. However, 9-methylphenanthrene (9MP) and dibenzothiophene (DBT) were weakly degraded. The degradation rates of 9MP and DBT increased in the presence of 2MP, whilst the degradation rate of 2MP increased in the presence of 9MP. However, the presence of DBT inhibited the degradation of 2MP. DBT sulfone, a DBT metabolite, was not assimilated by the bacteria and its presence also decreased the degradation rate of 2MP.

Abstract
This preliminary study was designed to develop empirically a scale of compulsive sexual behavior (CSB) and to test its reliability and validity in a sample of individuals with nonparaphilic CSB (N = 15), in a sample of pedophiles (N = 35) in treatment for sexual offending, and in a sample of normal controls (N = 42). Following a factor analysis and a varimax rotation, those items with factor loadings on the rotated factors of greater than .60 were retained. Three factors were identified, which appeared to measure control, abuse, and violence. Cronbach's alphas indicated that the subscales have good reliability. The 28-item scale was then tested for validity by a linear discriminant function analysis. The scale successfully discriminated the nonparaphilic CSB sample and the pedophiles from controls. Further analysis indicated that this scale is a valid measure of CSB in that there were significant differences between the three groups on the control subscale. Pedophiles scored significantly lower than the other two groups on the abuse subscale, with the other two groups not scoring significantly differently from one another. This indicated that pedophiles were more abusive than the nonparaphilic CSB individuals or the controls. Pedophiles scored significantly lower than controls on the violence subscale. Nonparaphilic individuals with compulsive sexual behavior scored slightly lower on the violence subscale, although not significantly different. As a preliminary study, there are several limitations to this study, which should be addressed, in further studies with larger sample sizes.

Abstract
In order to evaluate the impact of an urban effluent on antibiotic resistance of freshwater bacterial populations, water samples were collected from the Arga river (Spain), upstream and downstream from the wastewater discharge of the city of Pamplona. Strains of Enterobacteriaceae (representative of the human and animal commensal flora) (110 isolates) and Aeromonas (typically waterborne bacteria) (118 isolates) were selected for antibiotic susceptibility testing. Most of the Aeromonas strains (72%) and many of the Enterobacteriaceae (20%) were resistant to nalidixic acid. Singly nalidixic acid-resistant strains were frequent regardless of the sampling site for Aeromonas, whereas they were more common upstream from the discharge for enterobacteria. The most common resistances to antibiotics other than quinolones were to tetracycline (24.3%) and beta-lactams (20.5%) for Enterobacteriaceae and to tetracycline (27.5%) and co-trimoxazole (26.6%) for Aeromonas. The rates of these antibiotic resistances increased downstream from the discharge at similar degrees for the two bacterial groups; it remained at high levels for enterobacteria but decreased along the 30-km study zone for Aeromonas. Genetic analysis of representative strains demonstrated that these resistances were mostly (enterobacteria) or exclusively (Aeromonas) chromosomally mediated. Moreover, a reference strain of Aeromonas caviae (CIP 7616) could not be transformed with conjugative R plasmids of enterobacteria. Thus, the urban effluent resulted in an increase of the rates of resistance to antibiotics other than quinolones in the riverine bacterial populations, despite limited genetic exchanges between enterobacteria and Aeromonas. Quinolone resistance probably was selected by heavy antibiotic discharges of unknown origin upstream from the urban effluent.

Abstract
The Arga River is an interesting system in which to study the impact of urban effluent pollution because it receives a single effluent in the form of wastewater discharge from the city of Pamplona. To analyze the extent of this discharge, total bacteria, culturable heterotrophic bacteria, and Gram-negative heterotrophic bacteria were enumerated and 409 isolates of the latter were identified. One sampling station was located upstream from the inflow, while five were located up to 30 km downstream. Bacterial counts increased drastically downstream from the wastewater inflow. Total bacterial numbers decreased along the 30 km downstream, the last station attaining similar values to those recorded upstream from the discharge. However, culturable heterotrophic and Gram-negative heterotrophic bacteria levels generally remained significantly higher within the 30 km zone investigated. Among the 409 isolates identified, Aeromonas spp. were the most frequent both upstream and downstream from the discharge. In contrast, although strains belonging to different genera of Enterobacteriaceae were found in all stations, their occurrence was significantly higher just downstream from the polluted discharge. Acinetobacter spp., which were never found upstream, were detected in all stations below the discharge. Our results clearly show that the bacterial community structure changes definitively downstream from the discharge and that Aeromonas were common throughout the sampling zone. Thus they cannot be considered good indicators of pollution in this setting compared to some genera of Enterobacteriaceae or some species of Acinetobacter, the distribution of which correlated better with the distance from the wastewater discharge.

Abstract
Serum leptin levels are low in untreated anorexia nervosa, but studies of the exact relationship between leptin and body weight and the impact of refeeding in anorectics are limited. Therefore, we studied serum leptin, insulin-like growth factor I, and other endocrine parameters in female anorectics before and after gaining weight and in female normal body weight controls. Leptin levels in untreated anorectics were significantly lower than those in normal body weight controls (3.6 +/- 1.6 vs. 12.0 +/- 6.9 ng/mL; P < 0.001), and they uncoupled from body weight in a nonlinear relationship, suggesting a threshold effect at lowest body weights. Leptin increased significantly with refeeding (5.6 +/- 3.8 ng/mL; P < 0.01). The significant linear correlations of leptin with body mass index in the anorectics after weight gain and in normal body weight controls (r = 0.69; P < 0.001 and r = 0.76; P < 0.001, respectively) are consistent with a normal physiological increase in leptin with weight gain. Leptin and insulin-like growth factor I were highly correlated, even after controlling for body weight (r = 0.63; P = 0.001) during starvation, but were no longer significantly correlated after body weight gain in the anorectics or the normal body weight controls. Further studies are necessary to elucidate the relationship of leptin to neuroendrocrine abnormalities seen in starvation and to determine a possible contribution of leptin to difficulties with weight restoration in anorexia nervosa.

Abstract
The incidence of end-stage renal failure (ESRF) is higher in the Indo-Asian ethnic group as compared to the White. To investigate whether this might be associated with faster rates of progression to ESRF in Indo-Asian diabetic patients, we studied a total of 39 Type 2 diabetic patients, using the Department of Nephrology database showing serial serum creatinine measurements from the time of first referral to the clinic until they reached a level of >500 micromol l(-1) or ESRF requiring renal replacement therapy (RRT), either dialysis or renal transplantation. They were grouped into Indo-Asian (n = 24) and White (n = 15). The rate of progression of those who developed ESRF, calculated as the slope of log serum creatinine against time, was not significantly different between the Indo-Asian and White patients, p = 0.73. We conclude that the higher incidence of ESRF in the Indo-Asian Type 2 diabetic patient with nephropathy is therefore not due to a faster rate of deterioration in renal function.

Abstract
Complement plays important roles in host immune defences, and recent studies suggest that adipose tissue is an important site of production for some complement proteins. Starvation has been associated with low complement levels, but studied populations have usually had concomitant opportunistic infections or other conditions which might affect complement levels. To determine the impact of body weight and changes in body weight on serum complement, we investigated levels of complement proteins in otherwise healthy patients with a wide range of body weights, including patients with anorexia nervosa before and after treatment, obese dieters before and after weight loss, and normal weight controls. We found that complement proteins of the alternative pathway (C3, B, and D), alternative pathway haemolytic activity (AP50) and the inhibitors H and I were low in starving anorectics and normalized with weight gain. C3a levels were comparable in anorectics at low weight and after weight gain, indicating that low serum complement levels were attributable to hypoproduction and not complement cascade activation with consumption. Further, levels of C3, B, AP50, H and I, but not D, were higher than controls in obese patients and decreased toward normal after weight loss. Overall, percentage of ideal body weight, changes in body weight, and serum transferrin were each highly correlated with serum levels of complement proteins. We conclude that levels of alternative pathway complement components are determined in part by factors that influence body weight and by weight changes, possibly due to changes in production in adipose tissue or at other sites.

Abstract
The examination of psychopathology in subgroups of obese patients is a new area of research in psychiatry. This project studied rates and types of psychopathology among obese subjects meeting the proposed DSM-IV criteria of binge eating disorder (BED) and obese subjects without BED. One hundred obese women with a mean age of 39.2 years and a mean body mass index (BMI) of 35.9 kg/m2 were evaluated using the Structured Clinical Interview for DSM-III-R (SCID-Modified Version) and a self-rating personality inventory, Personality Diagnostic Questionnaire-Revised (PDQ-R), before entering a treatment study for weight reduction. Those subjects meeting proposed DSM-IV criteria for BED had significantly higher lifetime rates for an axis I diagnosis compared with those that did not meet criteria for BED. Subjects with BED showed higher rates of lifetime affective disorder and bulimia nervosa, but did not differ on any other axis I diagnoses. Axis II cluster B and cluster C diagnoses were found more frequently among BED subjects. The specific diagnoses of histrionic, borderline, and avoidant personality disorders were found significantly more often among BED subjects. The results support the idea that binge eating may identify a distinct subgroup among the obese population who have significantly higher rates of certain forms of psychopathology on both Axis I and Axis II. The findings of increased rates of depression are consistent with other studies and suggest that our treatment modalities need to address this problem.

Abstract
The treatment literature on bulimia nervosa includes several double-blind placebo controlled studies, the majority of which examine the use of antidepressants in bulimia nervosa. The psychotherapy literature has focused heavily on the use of cognitive behavioral therapy (CBT) in the treatment of this eating disorder. Some studies have compared CBT to other types of therapy or waiting list controls. The following review will examine the methodology and outcome of the pharmacotherapy and psychotherapy treatment studies of bulimia nervosa. The authors conclude that while the studies indicate treatment is somewhat effective, there remains uncertainty regarding the long-term effectiveness of most of the reported treatments.

Abstract
A reanalysis of treatment response and relapse was performed using survival analysis in a 12-week clinical trial of cognitive behavioral group psychotherapy for the treatment of bulimia nervosa. One hundred forty-three (143) bulimic women with high incidence of binge eating, self-induced vomiting, and/or laxative abuse were randomly assigned to one of four possible treatment conditions that consisted of a combination of two factors: (1) emphasis on abstinence (high and low), and (2) treatment intensity (high and low). "Initial" and "maintained" response to treatment based on "total" and "near" abstinence criteria were determined using self-reported binge eating, vomiting, and laxative use data. Results suggest that an emphasis on abstinence appears important in achieving initial abstinence, whereas intensity of treatment may be important in maintaining abstinence.
