RESUMO

"The Accept Voices© is a useful intervention for the management and acceptance of auditory verbal hallucinations in people with schizophrenia. This study aims at determining if the clinical effects remained at six- and 12-month follow-ups. Results show that participants (N = 22) maintained a decrease in auditory hallucinations, at the six and 12 months follow ups for severity and acceptance of Voices, anxiety and depression. Accept Voices© shows promise as a potential treatment for people with schizophrenia struggling with Voices.

RESUMO

Head and neck squamous cell carcinoma (HNSCC) is a heterogeneous disease with significant mortality and frequent recurrence. Prior efforts to transcriptionally classify HNSCC into groups of varying prognoses have identified four accepted molecular subtypes of the disease: Atypical (AT), Basal (BA), Classical (CL), and Mesenchymal (MS). Here, we investigate the active enhancer landscapes of these subtypes using representative HNSCC cell lines and identify samples belonging to the AT subtype as having increased enhancer activity compared to the other 3 HNSCC subtypes. Cell lines belonging to the AT subtype are more resistant to enhancer-blocking bromodomain inhibitors (BETi). Examination of nascent transcripts reveals that both AT TCGA tumors and cell lines express higher levels of enhancer RNA (eRNA) transcripts for enhancers controlling BETi resistance pathways, such as lipid metabolism and MAPK signaling. Additionally, investigation of higher-order chromatin structure suggests more enhancer-promoter (E-P) contacts in the AT subtype, including on genes identified in the eRNA analysis. Consistently, known BETi resistance pathways are upregulated upon exposure to these inhibitors. Together, our results identify that the AT subtype of HNSCC is associated with higher enhancer activity, resistance to enhancer blockade, and increased signaling through pathways that could serve as future targets for sensitizing HNSCC to BET inhibition.

RESUMO

OBJECTIVE: Suicide prevention certainly includes a better knowledge of suicide risk in primary care. A number of international publications have shown interest in assessing this risk, but mostly through specific consultant populations: young patients, old patients, anhedonic, depressive, etc. Our study analyses suicide risk prevalence in patients consulting in general medicine for any somatic or psychiatric reason, their pathology or their age. METHOD: This cross-sectional study was conducted with adult patients (827 subjects included) who were consulting a French generalist doctor panel randomly selected. They filled a validated self-questionnaire (aRSD) assessing their suicide risk in the 15 preceding days and providing professional and personal data. RESULTS: The totally operable 757 files (483 female; 274 male) show that close to a quarter of consultants (24.3%) presents with a positive suicide risk in the 15 days preceding their consultation and 6.3%, reveal a severe risk (aRSD ≥ 7) with ideas and impulses to commit the act. When the reason to consult is psychiatric, 64.6% of these consultants have aRSD positive. One time out of two, the risk is even severe. CONCLUSIONS: This data shows how important the suicide risk prevalence is in general medicine. It confirms the main role played by primary care patricians in acting to prevent suicide risk. This data also shows the contribution represented by a self-questionnaire that would rapidly assess the suicide intent while screening, it.

RESUMO

AIM OF THE STUDY: The objective of this study was to evaluate the potential impact of a third wave CBT group intervention for the management of auditory hallucinations in patients with schizophrenia. METHOD: 38 patients with schizophrenia presenting with auditory hallucinations, followed in mental health services, participated in six sessions of a group based on acceptance and engagement therapy (ACT). The study followed a repeated single case experimental design (type A-B-A) based on the principle of a control phase followed by an intervention phase and a follow-up phase of similar duration. The various measurements were administered during the control phase, at pre-/post-group and six weeks after the last group session. RESULTS: The results show a significant decrease in auditory hallucinations, as measured by the PSYRATS scale, during the treatment and follow-up phase, compared to the control phase. In addition, the participants saw significant reductions in depressive and anxious symptomatology (assessed with CDSS and SEAS), and increases in coping and acceptance in regards to voices (assessed using a study scale and VAAS). The level of Malevolence beliefs about voices (measured with BAVQ-R) also decreased significantly. CONCLUSIONS: A brief group intervention based acceptance show promise in the reduction of the intensity of auditory hallucinations, depression and anxiety in patients with schizophrenia, while improving their acceptance.

RESUMO

OBJECTIVES: Hearing voices is a common experience for people with schizophrenia. Perceived voices are in most cases a source of great distress for patients. This experience also exists in the general population and is considered as "non-clinical". Much research has focused on the psychological and neuropsychological mechanisms behind the emergence of voices. With regard to voice persistence factors, the acceptance of the voice-hearing phenomenon is still relatively unexplored. In addition, there are few standardized tools that specifically assess this dimension of voice experience. The Voices Acceptance and Actions Scale (VAAS) is the only validated tool to address voice acceptance in individuals with schizophrenia. However, to date, there is no French version. The objective of this research was to validate the VAAS in a French speaking population. METHOD: Our sample consisted of individuals with schizophrenia (N=65) and voice hearers from the general population (N=321). For the clinical population, individuals with schizophrenia and auditory hallucinations were assessed using the VAAS scale in its two abbreviated versions (9 and 12 items). In order to validate the measure in French, we administered psychopathology scales (BPRS) and voice belief scales (BAVQ-R) for convergent and divergent validity. For the non-clinical population, we administered the VAAS scale online (via LimeSurvey), accompanied by a brief sociodemographic questionnaire (age, sex, country of origin, existence of medical or psychological follow-up). RESULTS: The psychometric properties of the VAAS scale were satisfactory and similar to the original English-language tool for both versions, with a slight advantage for the one with 9-items. The convergent validity measured with the BAVQ-R scale, and the divergent one measured with the BPRS depression subscale, were found to be satisfactory. In addition, the re-test performed 6 weeks after the first test (N=30) was satisfactory for both scales, with a Pearson correlation index greater than 70 (r=0.70; P<0.001 for the VAAS 9 items) and (r=0.79; P<0.001 for the 12 item version). In individuals with schizophrenia (clinical population), the level of voice acceptance was low and strongly correlated with depression. This point seems to corroborate the current data in the field suggesting that voice hearing in this population is associated with significant distress and has a significant impact on their lives. Conversely, the level of acceptance obtained from the non-clinical population was much higher, reflecting a higher level of acceptance in this population. People from the non-clinical population seemed to accept and experience their voices with less distress than people from the clinical population in this study. CONCLUSION: To date, a paucity of studies have investigated the acceptance of auditory hallucinations. Our results support the psychometric validity of the French version of the VAAS, particularly the 9-item version. Furthermore, our study supports the need to continue studying voice acceptance, as it appears to be strongly linked to depression in people with psychiatric disorders such as schizophrenia. In addition, our study is novel in that it also explored, with a standardized tool, the level of voice acceptance in a non-clinical population and found people to be more accepting of the voices they hear and better at living with them. These data provide new evidence to better understand the links between the level of acceptance of voices, their experiences, and depression. Clinically, it seems essential to conduct more systematic and regular evaluations of the level of voice acceptance in those hearing voices. Finally, in terms of rehabilitation, voice acceptance can become a therapeutic target in order to improve the psychological and behavioral functioning of the person.

RESUMO

OBJECTIVES: Determine whether words contained in unsolicited patient complaints differentiate physicians with and without neurocognitive disorders (NCD). METHODS: We conducted a nested case-control study using data from 144 healthcare organizations that participate in the Patient Advocacy Reporting System program. Cases (physicians with probable or possible NCD) and two comparison groups of 60 physicians each (matched for age/sex and site/number of unsolicited patient complaints) were identified from 33,814 physicians practicing at study sites. We compared the frequency of words in patient complaints related to an NCD diagnostic domain between cases and our two comparison groups. RESULTS: Individual words were all statistically more likely to appear in patient complaints for cases (73% of cases had at least one such word) compared to age/sex matched (8%, p < 0.001 using Pearson's χ2 test, χ2 = 30.21, df = 1) and site/complaint matched comparisons (18%, p < 0.001 using Pearson's χ2 test, χ2 = 17.51, df = 1). Cases were significantly more likely to have at least one complaint with any word describing NCD than the two comparison groups combined (conditional logistic model adjusted odds ratio 20.0 [95% confidence interval 4.9-81.7]). CONCLUSIONS: Analysis of words in unsolicited patient complaints found that descriptions of interactions with physicians with NCD were significantly more likely to include words from one of the diagnostic domains for NCD than were two different comparison groups. Further research is needed to understand whether patients might provide information for healthcare organizations interested in identifying professionals with evidence of cognitive impairment.

RESUMO

BACKGROUND AND OBJECTIVES: Little is known about opioid prescribing for children without severe conditions. We studied the prevalence of and indications for outpatient opioid prescriptions and the incidence of opioid-related adverse events in this population. METHODS: This retrospective cohort study between 1999 and 2014 included Tennessee Medicaid children and adolescents aged 2 to 17 without major chronic diseases, prolonged hospitalization, institutional residence, or evidence of a substance use disorder. We estimated the annual prevalence of outpatient opioid prescriptions and incidence of opioid-related adverse events, defined as an emergency department visit, hospitalization, or death related to an opioid adverse effect. RESULTS: There were 1 362 503 outpatient opioid prescriptions; the annual mean prevalence of opioid prescriptions was 15.0%. The most common opioid indications were dental procedures (31.1% prescriptions), outpatient procedure and/or surgery (25.1%), trauma (18.1%), and infections (16.5%). There were 437 cases of opioid-related adverse events confirmed by medical record review; 88.6% were related to the child's prescription and 71.2% had no recorded evidence of deviation from the prescribed regimen. The cumulative incidence of opioid-related adverse events was 38.3 of 100 000 prescriptions. Adverse events increased with age (incidence rate ratio = 2.22; 95% confidence interval, 1.67-2.96; 12-17 vs 2-5 years of age) and higher opioid doses (incidence rate ratio = 1.86 [1.45-2.39]; upper versus lower dose tertiles). CONCLUSIONS: Children without severe conditions enrolled in Tennessee Medicaid frequently filled outpatient opioid prescriptions for acute, self-limited conditions. One of every 2611 study opioid prescriptions was followed by an opioid-related adverse event (71.2% of which were related to therapeutic use of the prescribed opioid).

RESUMO

INTRODUCTION: Maternal burn-out is a psychological, emotional and physiological condition resulting from the accumulation of various stressors characterised by a moderate but also a chronic and repetitive dimension. Little research has focused on this syndrome. OBJECTIVE: The current study aims to assess maternal burn-out rate and to identify factors associated with this state of exhaustion. METHOD: 263 French mothers aged between 20 and 49 years answered five scales quantifying maternal burn-out, perceived social support, parental stress, depression and anxiety symptoms and history of postnatal depression. RESULTS: About 20% of mothers were affected by maternal burn-out. The main factors related to maternal burn-out were having a child perceived as difficult, history of postnatal depression, anxiety, satisfaction of a balance between professional and personal life and parental stress. CONCLUSION: This research shows the need for further work on maternal burn-out to better understand and prevent this syndrome.

RESUMO

Environmental cofactors alter host-pathogen interactions and influence disease dynamics by impairing host resistance and/or increasing pathogen virulence. Terrestrial runoff is recognized as a major threat to coral reef health. However, the direct links between runoff and coral disease are not clear. Montipora white syndrome (MWS) is a coral disease that occurs in the Hawaiian archipelago, can be caused by various bacterial pathogens, including Vibrio species, and is linked to conditions associated with heavy rainfall and runoff. The objective of this study was to determine whether a short-term hyposalinity stress (20 ppt for 24 h) or sedimentation stress (1000 g m-2 d-1) would influence bacterial infection of the coral Montipora capitata. Hyposalinity increased M. capitata susceptibility to infection by 2 MWS pathogens, Vibrio coralliilyticus strain OCN008 and Vibrio owensii strain OCN002. Specifically, hyposalinity allowed OCN008 to infect at lower doses (106 CFU ml-1 compared with 108 CFU ml-1) and reduced the amount of time before onset of OCN002 infection at high doses (108 CFU ml-1). In contrast, short-term sedimentation stress did not affect M. capitata infection by either of these 2 pathogens. Although several studies have found a correlation between runoff and increased coral disease prevalence in field studies, this is the first study to show that one aspect of runoff (reduced salinity) enhances bacterial infection of coral using manipulative experiments.

RESUMO

BACKGROUND: Delayed completion of human papillomavirus vaccination (4vHPV) series is common. We sought to identify factors associated with delay. METHODS: This substudy was part of a large prospective, multi-site study recruiting 9-17 year old girls at the time of their third 4vHPV dose to assess immunogenicity associated with prolonged dosing intervals. At participating sites, parents/legal guardians (caregivers) of all enrolled girls (9-17 years old) and enrolled girls aged 14-17 years were approached for participation. Caregivers completed a questionnaire measuring adolescent and caregiver sociodemographic characteristics, caregiver attitudes and beliefs about on-schedule HPV vaccination and HPV vaccine safety, adolescent's health behaviors, barriers to accessing health care, provider office vaccination practices and a Rapid Estimate of Adult Literacy in Medicine (REALM). Participating girls completed a separate questionnaire measuring their attitudes and beliefs about on-schedule HPV vaccination and HPV vaccine safety. Delay was defined as receiving the third 4vHPV dose >12 months after the first. Bivariate, multinomial logistic regression and multivariate logistic regression analyses were used to identify factors predicting delayed completion. RESULTS: Questionnaires were completed by 482 caregivers and 386 adolescents; 422 caregivers completed a REALM. Delayed 4vHPV dosing occurred in most adolescents (67%). In multivariate analyses, predictors of delayed completion included caregiver demographic factors (self-reported black vs. white race and high school or less education vs. college or more) and an interaction between caregiver's inability to get an immunization appointment as soon as needed and adolescent's type of insurance. CONCLUSIONS: Caregiver's race and educational level, accessibility of immunization appointments, and adolescent's insurance type were found to be related to delays in completion of 4vHPV, but caregiver or adolescent attitudes and beliefs about on-schedule HPV vaccination or HPV vaccine safety were not. Therefore, interventions to improve adherence to recommended vaccination schedules could benefit from a focus on improving access to immunizations. ClinicalTrials.gov (NCT01030562).

RESUMO

BACKGROUND: The originally recommended dosing schedule, 0, 2, 6 months, for the 3-dose quadrivalent human papillomavirus vaccine (4vHPV) was often not followed, resulting in longer than recommended intervals between doses and interest in the effect of prolonged intervals. Recent two-dose recommendations require investigations into the effect of delaying dose 2. METHODS: This multi-site, prospective study enrolled healthy 9-17 year old girls (n = 1321) on the day of or within 28 days following a third dose of 4vHPV vaccination. Antibody titers to 4vHPV types were measured at one and six months post-dose 3 from all participants and post-dose 2 from participants who were on time for dose 3. To compare antibody responses, participants were categorized into groups: second and third doses on time (control group); on-time dose 2, substantially late dose 3 (group 2); substantially late dose 2, on-time dose 3 (group 3); both doses substantially late (group 4). Analyses compared age-adjusted geometric mean titers (GMTs) at one-month and six-months post-dose 3, effect of delaying the second dose, and two versus three doses as well as post-dose 2 GMTs, stratified by age. RESULTS: Compared to on-time dosing, one-month post-dose 3 GMTs were non-inferior in groups 2, 3, and 4 and were superior in group 2. Six month post-dose 3 GMTs were superior in groups 2, 3, and 4 for each genotype, except HPV 18 in group 3. Age-adjusted post does 2 titers were significantly lower than post-dose 3 titers when dose 2 was on time but were significantly higher when dose 2 was substantially late. Participants ≥15 years old had no difference in post-dose 2 titers compared to <15 year olds when dose 2 was substantially delayed. CONCLUSIONS: Prolonged intervals between doses do not appear to diminish and may enhance antibody response to 4vHPV. ClinicalTrials.gov (NCT00524745).

RESUMO

PURPOSE: Previous research has indicated that patients with anorexia nervosa (AN) or atypical AN with premorbid history of overweight/obesity have greater weight loss and longer illness duration than patients with no such history. However, little is known about the association of premorbid overweight/obesity and receiving inpatient medical care during treatment for an eating disorder. METHODS: Using logistic regression, we sought to determine if history of overweight/obesity was associated with receiving inpatient medical care in a sample of 522 patients (mean age 15.5 years, 88% female) with AN/atypical AN. RESULTS: Binary results demonstrated greater percent weight loss (27.4% vs. 16.2%) and higher percent median body mass index (%mBMI, 99.8% vs. 85.2%) at presentation in those with a history of overweight/obesity (p < .001) but no difference in duration of illness (p = .09). In models adjusted for demographics and percent weight loss, history of overweight/obesity was associated with lower odds of receiving inpatient medical care (odds ratio .60 [95% confidence interval: .45-.80]) at 1-year follow-up. However, these associations were no longer significant after adjusting for %mBMI. Mediation results suggest that %mBMI fully mediates the relationship between history of overweight/obesity and inpatient medical care, in that those with a history of overweight/obesity are less likely to receive care due to presenting at a higher weight. CONCLUSIONS: Our findings suggest that, despite greater degree of weight loss and no difference in duration of illness, participants with a history of overweight/obesity are less likely to receive inpatient medical care.

RESUMO

The objective was to determine effects of nursery group-size-floor space allowance on growth, physiology, and hematology of replacement gilts. A 3 × 3 factorial arrangement of treatments was used wherein gilts classified as large, medium, or small ( = 2537; BW = 5.6 ± 0.6 kg) from 13 groups of weaned pigs were placed in pens of 14, 11, or 8 pigs resulting in floor space allowances of 0.15, 0.19, or 0.27 m/pig, respectively. Pigs were weighed on d 0 (weaning) and d 46 (exit from nursery). The ADG was affected by group-size-floor space allowance × pig size ( = 0.04). Large- and medium-size gilts allowed the most floor space had greater ( < 0.05) ADG than similar size gilts allowed the least floor space but for small size gilts there was no effect ( > 0.05) of group size-floor space allowance. Mortality in the nursery was not affected ( > 0.05) by treatment, size, or treatment × size and overall was approximately 2.1%. Complete blood counts and blood chemistry analyses were performed on samples collected at d 6 and 43 from a subsample of gilts ( = 18/group-size-floor space allowance) within a single group. The concentration ( < 0.01) and percentage ( = 0.03) of reticulocytes was the least and red blood cell distribution width the greatest ( < 0.01) in gilts allowed 0.15 m floor space (effects of treatment). Blood calcium was affected by treatment ( = 0.02) and concentrations for gilts allowed the greatest and intermediate amounts of floor space were greater ( < 0.05) than for gilts allowed the least floor space. Serum concentrations of cortisol were not affected by treatment × day ( = 0.27). Cortisol concentrations increased from d 6 to d 43 in all groups and were affected by day ( < 0.01) but not treatment ( = 0.53). Greater space allowance achieved by placing fewer pigs per pen in the nursery affected blood parameters and resulted in large- and medium-size replacement gilts displaying increased ADG. Further study will determine if these effects influence lifetime reproductive capacity and sow longevity.

RESUMO

The objective was to determine the effects of immunization against gonadotropin-releasing hormone on reproductive characteristics in boars. A total of 72 boars were used in a randomized design with three treatments: single immunization (SI) (10 weeks of age) or double immunization (DI) (10 and 15 weeks of age) with Improvest® and intact controls (no Improvest®; CNT) (n=24/group). At 10, 15, 20, 25 and 40 weeks of age, blood was collected and serum harvested to evaluate testosterone concentrations. Testosterone concentrations were less for DI boars compared with CNT boars and SI boars at 20 and 25 weeks (P<0.001), but not at 40 weeks of age. At week 25, 18 pigs (n=6/group) were sacrificed and testes were removed, weighed and measured, and seminiferous tubules were examined and scored using histological slides of testes parenchyma. A sample of neck fat was assessed for boar taint aroma. All testicular measurements and weights and seminiferous tubule scores were less for DI boars compared with SI and CNT boars (P<0.001). More (P<0.05) SI and CNT boars had detectable boar taint aroma than DI boars. Libido was assessed at 32, 36, 47, 60 and 63 weeks of age and semen collected at 60 weeks of age was analyzed for indicators of quality. There were no effects of treatment (P=0.41) or treatment by week (P=0.71) on libido. Semen volume, gel weight and total number of sperm cells, determined in a subset of boars (n=3/treatment), were not different among treatments. Sperm concentration was greater for DI than SI (P=0.01), and tended to be greater for DI compared with CNT (P=0.10). Sperm motility tended to be greater for DI boars compared with CNT boars (P=0.066). In conclusion, our results show that there are no long-term effects of immunocastration on reproductive characteristics in boars.

RESUMO

BACKGROUND: Cytomegalovirus (CMV) is a leading cause of congenital infection and an important target for vaccine development. METHODS: CMV seronegative girls between 12 and 17 years of age received CMV glycoprotein B (gB) vaccine with MF59 or saline placebo at 0, 1 and 6 months. Blood and urine were collected throughout the study for evidence of CMV infection based on PCR and/or seroconversion to non-vaccine CMV antigens. RESULTS: 402 CMV seronegative subjects were vaccinated (195 vaccine, 207 placebo). The vaccine was generally well tolerated, although local and systemic adverse events were significantly more common in the vaccine group. The vaccine induced gB antibody in all vaccine recipients with a gB geometric mean titer of 13,400 EU; 95%CI 11,436, 15,700, after 3 doses. Overall, 48 CMV infections were detected (21 vaccine, 27 placebo). In the per protocol population (124 vaccine, 125 placebo) vaccine efficacy was 43%; 95%CI: -36; 76, p=0.20. The most significant difference was after 2 doses, administered as per protocol; vaccine efficacy 45%, 95%CI: -9; 72, p=0.08. CONCLUSION: The vaccine was safe and immunogenic. Although the efficacy did not reach conventional levels of significance, the results are consistent with a previous study in adult women (Pass et al.

RESUMO

BACKGROUND: As with most mental health disorders, the topic of hazing is not exclusive to the student athlete. However, it is also clear that the unique set of situations faced by athletes create a set of additional and difficult challenges to their mental and physical well-being. A deep-rooted culture, a lack of knowledge about hazing and its causal relationships, and a failure to act by teammates and adults all play a role in the propagation of this danger. Also, in an era where the popular press similarly celebrates and chastises episodes of hazing, it is increasingly crucial to turn to the scientific literature for guidance. PURPOSE: To provide a comprehensive review of the scientific research on hazing in sports and to make recommendations for enhancing the approach and assistance to those in need on an individual and societal level. STUDY DESIGN: Qualitative literature review of hazing in collegiate and school sports. METHODS: Databases including PubMed, Google Scholar, SPORTDiscus, EMBASE and MEDLINE were searched using standardised terms, alone and in combination, including 'hazing', 'bullying', 'sport', 'athlete', 'college', 'school' and 'youth'. FINDINGS: Despite increased attention to its dangers, hazing remains pervasive throughout the sports world. However, many do not recognise those actions as consistent with hazing. A change in culture, increased education and awareness, along with methodologically sound strategies for action must occur in order to reduce the ill effects and cycle of hazing. To date, current information and efforts are lacking.

RESUMO

BACKGROUND: The use of opioids is increasing in children; therefore, opioid toxicity could be a public health problem in this vulnerable population. However, we are not aware of a published algorithm to identify cases of opioid toxicity in children using administrative databases. We sought to develop an algorithm to identify them. After review of literature and de-identified computer profiles, a broad set of ICD-9 CM codes consistent with serious opioid toxicity was selected. Based on these codes, we identified 195 potential cases of opioid toxicity in children enrolled in Tennessee Medicaid. Medical records were independently reviewed by two physicians; episodes considered equivocal were reviewed by an adjudication committee. Cases were adjudicated as Group 1 (definite/probable), Group 2 (possible), or Group 3 (excluded). RESULTS: Of the 195 potential cases, 168 (86.2%) had complete records for review and 85 were confirmed cases. The overall positive predictive value (PPV) for all codes was 50.6%. The PPV for codes indicating: unintentional opioid overdose (25/31) was 80.7%; intentional opioid overdose (15/30) was 50.0%, adverse events (33/58) was 56.9%, the presence of signs or symptoms compatible with opioid toxicity (12/47) was 25.5%, and no cases were confirmed in records from the two deaths. Of the confirmed cases, 65.8% were related to therapeutic opioid use. CONCLUSION: For studies utilizing administrative claims to quantify incidence of opioid toxicity in children, our findings suggest that use of a broad set of screening codes coupled with medical record review is important to increase the completeness of case ascertainment.

RESUMO

PURPOSE: Psychopharmacologic medications are often prescribed to patients with restrictive eating disorders (EDs), and little is known about the frequency of use in adolescents. We examined the use of psychopharmacologic medications in adolescents referred for treatment of restrictive ED, potential factors associated with their use, and reported psychiatric comorbidities. METHODS: Retrospective data from the initial and 1-year visits were collected for patients referred for evaluation of restrictive ED at 12 adolescent-based ED programs during 2010 (Group 1), including diagnosis, demographic information, body mass index, prior treatment modalities, and psychopharmacologic medications. Additional data regarding patients' comorbid psychiatric conditions and classes of psychopharmacologic medications were obtained from six sites (Group 2). RESULTS: Overall, 635 patients met inclusion criteria and 359 had 1-year follow-up (Group 1). At intake, 20.4% of Group 1 was taking psychopharmacologic medication and 58.7% at 1 year (p ≤ .0001). White, non-Hispanic race (p = .020), and prior higher level of care (p < .0001) were positively associated with medication use at 1 year. Among Group 2 (n = 256), serotonin reuptake inhibitors/serotonin-norepinephrine reuptake inhibitors use was most common, and 62.6% had a reported psychiatric comorbidity. Presence of any psychiatric comorbidity was highly associated with medication use; odds ratio, 10.0 (5.6, 18.0). CONCLUSIONS: Adolescents with restrictive ED treated at referral centers have high rates of reported psychopharmacologic medication use and psychiatric comorbidity. As more than half of this referral population were reported to be taking medication, continued investigation is warranted to ensure the desired outcomes of the medications are being met.

RESUMO

In the presence of physical and psychological disturbances in the postpartum period, perceived social support is often regarded as a protective factor in women's mental health. This work evaluates the psychometric properties of the French version of a questionnaire widely used internationally to measure perceived social support, which has not been yet validated in French: the Multidimensional Scale of Perceived Social Support (MSPSS). This study collected data from 148 women (30.5 ± 5.12 years) who agreed to complete the MSPSS and a scale assessing symptoms of postpartum depression (Edinburgh Post-Natal Depression Scale, EPDS) 1 and 4 months after childbirth. The results confirm the original three-factor structure of the scale. The Cronbach's alpha coefficients are excellent. The total scale score is correlated with all three dimensions and a significantly negative correlation is found between MSPSS and EPDS. The results suggest that the French tool has generally good internal reliability. The MSPSS can provide useful data helping to identify French-speaking people at risk for negative feelings (e.g., mood disorders of perinatal period).
