RESUMEN

We assessed the performance of the VITEK® MS IVD V3.0 matrix-assisted laser desorption ionization - time of flight mass spectrometry (MALDI-ToF MS) V3.0 database for the identification of Nocardia spp. as compared with targeted DNA sequencing. A collection of 222 DNA sequence-defined Nocardia spp. strains encompassing 18 different species present or not in the database was tested. Bromocresol purple agar (BCP) and Columbia agar +5% sheep's blood (COS) culture media were used together with two different preparation steps: direct smear and a "3 attempts" procedure that covered (1) spotting of an extract, (2) new spotting of the same extract, and (3) spotting of a new extract. The direct smear protocol yielded low correct identification rates (≤ 15% for both media) whereas protein extraction yielded correct identification results (> 67% regardless of the media used.). The use of 2 additional attempts using repeat or new extracts increased correct identification rates to 87% and 91% for BCP and COS, respectively. When using the 3 attempts procedure, the best identification results, independent of media types, were obtained for N. farcinica and N. cyriacigeorgica (100%). Identification attempts 2 and 3 allowed to increase the number of correct identifications (BCP, +20%; COS, +13%). The enhancement in performance during attempts 2 and 3 was remarkable for N. abscessus (81% for both media) and low prevalence species (BCP, 70%; COS, 85%). Up to 3.4% and 2.4% of the strains belonging to species present in the database were misidentified with BCP and COS media, respectively. In 1.9% of the cases for BCP and 1.4% for COS, these misidentifications concerned a species belonging to the same phylogenetic complex. Concerning strains that are not claimed in the V3.0 database, N. puris and N. goodfellowi generated "No identification" results and 100% of the strains belonging to N. arthritidis, N.cerradoensis, and N. altamirensis yielded a misidentification within the same phylogenetic complex. Vitek® MS IVD V3.0 is an accurate and useful tool for identification of Nocardia spp.

RESUMEN

OBJECTIVES: There is limited evidence available on the health-seeking behaviours of individuals in relation to determinants of healthcare use. This study aimed to analyse the determinants of healthcare use (including both hospital and outpatient services) among homeless people with severe mental health illnesses. STUDY DESIGN: The study used data from a multicentre, randomised, controlled trial conducted in four large French cities (the French Housing First Study). METHODS: Data were drawn from 671 homeless people enrolled in the study between August 2011 and April 2014. Mobile mental health outreach teams recruited homeless individuals with severe mental health illnesses who were living on the street or in emergency shelters, hospitals or prisons. Data collection was performed during face-to-face interviews. Healthcare service use included hospitalisations, mental health and regular emergency department (ED) visits and outpatient visits to healthcare facilities or physicians' offices over a 6-month follow-up period. The data were analysed with zero-inflated (ZI) two-part models. RESULTS: In total, 61.1% of participants had at least one hospitalisation stay over the previous 6 months, with a mean of 25 (+/- 39.2) hospital days, and the majority (51%) had visited the ED (either for regular or mental health issues) during the same time period. The results confirmed the role of financial barriers (resources and health insurance) in seeking hospital care (P < 0.05). The main predictors for hospital use in the study population were a better social functioning score (odds ratio [OR]: 1.03; P < 0.001) and having schizophrenia (OR: 1.39; P < 0.01). Higher mental health scores (assessed by the Medical Outcomes Study 36-item Short Form Health Survey) (OR: 1.03, P < 0.01) and alcohol dependence (OR: 2.13; P < 0.01) were associated with not using ED healthcare services. Being 'absolutely homeless' predicted an increased use of the ED and a zero use of outpatient services. Inversely, no association with factors related to the homelessness trajectory was found in hospital ZI negative binomial models. CONCLUSION: This study is important because a comprehensive understanding of the determinants of healthcare use enables healthcare systems to adapt and develop. The efficiency of medicosocial interventions targeting the homeless population with mental health illnesses must also be assessed. CLINICAL TRIAL NUMBER: NCT01570712.

RESUMEN

BACKGROUND: Increasing numbers of programs are addressing the specific needs of homeless people with schizophrenia in terms of access to housing, healthcare, basic human rights and other domains. Although quality of life scales are being used to evaluate such programs, few instruments have been validated for people with schizophrenia and none for people with schizophrenia who experience major social problems such as homelessness. The aim of the present study was to validate the French version of the S-QoL a self-administered, subjective quality of life questionnaire specific to schizophrenia for people with schizophrenia who are homeless. METHODS: In a two-step process, the S-QoL was first administered to two independent convenience samples of long-term homeless people with schizophrenia in Marseille, France. The objective of the first step was to analyse the psychometric properties of the S-QoL. The objective of the second step was to examine, through qualitative interviews with members of the population in question, the relevance and acceptability of the principle quality of life indicators used in the S-QoL instrument. RESULTS: Although the psychometric characteristics of the S-QoL were found to be globally satisfactory, from the point of view of the people being interviewed, acceptability was poor. Respondents frequently interrupted participation complaining that questionnaire items did not take into account the specific context of life on the streets. CONCLUSIONS: Less intrusive questions, more readily understandable vocabulary and greater relevance to subjects' living conditions are needed to improve the S-QoL questionnaire for this population. A modular questionnaire with context specific sections or specific quality of life instruments for socially excluded populations may well be the way forward.

RESUMEN

OBJECTIVE: The aim of this study was to investigate the factors associated with non-adherence to medication in a large multi-center sample of homeless schizophrenia (HSZ) patients. METHODS: This multi-center study was conducted in four French cities: Lille, Marseille, Paris, and Toulouse. In addition to the Medication Adherence Rating Scale (MARS), sociodemographic information, history of homelessness, illness severity using the Modified Colorado Symptom Index (MCSI) and the Multnomah Community Integration Scale (MCAS), and drug information were collected. RESULTS: In total, 218 HSZ patients (16.1% women, mean age 36.8 ± 9.3 years) were included in this study. In the multivariate analysis, being a woman and having higher illness severity (MCSI score) and lower "acceptance of illness" (MCAS score) were significantly associated with lower MARS index scores. Compared to men, women had lower MARS dimension 1 ('medication adherence behavior') and dimension 3 ('negative side effects and attitudes toward psychotropic medication') scores. First-generation antipsychotic use was also associated with lower MARS dimension 3 scores. CONCLUSION: HSZ women reported lower adherence than men, mainly due to having more subjective negative side effects and worse attitudes toward psychotropic medication. Future longitudinal studies should confirm these findings and explore the applicability of specific pharmacological and non-pharmacological treatment strategies for HSZ women, including treatment dose adaptation and psychoeducation. Clinical trial number NCT01570712.

RESUMEN

Typing of bacterial isolates using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) potentially provides an efficient on-site method to monitor the spread of antibiotic-resistant bacteria and rapidly detect outbreaks. We compared MALDI-MS typing results to those of amplified fragment length polymorphism (AFLP) in a collection of 52 ESBL-producing Escherichia coli, isolated in a Dutch nursing home with an on-going outbreak of ST131 E. coli. Specific MALDI types were defined based on spectral data from four replicate colony samples of isolates grown on Columbia agar using multivariate statistical procedures. Type-specific superspectra were computed for four E .coli MALDI-types and tested for the potential of rapid and automated typing. The effect of different incubation conditions on typing performance was tested by analysing five isolates incubated for 24 h and 48 h on five different media. Types defined based on MALDI spectra were largely in agreement with the AFLP results, although some MALDI types comprised of more than one AFLP type. In particular, isolates belonging to ST131 showed distinct mass patterns. The proportion of isolates correctly assigned was substantially lower for isolates incubated on Sabouraud-dextrose and Drigalski agars for 24 h, and for those incubated for 48 h (all media). Our results show that the identification of type-specific peaks potentially allows direct typing of isolates belonging to specific clonal lineages. Both incubation time and media affected type assignment, suggesting that there is a need for a careful standardization of incubation time and culturing conditions when developing MALDI-typing schemes for E. coli.

RESUMEN

OBJECTIVE: To evaluate the efficacy of the hands and knees position during the first stage of labour to facilitate the rotation of the fetal head to the occiput anterior position. DESIGN: Randomised controlled trial. SETTING: Geneva University Hospitals, Switzerland. POPULATION: A total of 439 women with a fetus in the occiput posterior position during the first stage of labour. METHODS: The women in the intervention group were invited to take a hands and knees position for at least for 10 minutes. Women allocated to the control group received the usual care. For both groups, 15 minutes after randomisation, women completed a short questionnaire to report their perceived pain and the comfort of their position. MAIN OUTCOME MEASURES: The rotation of the fetal head in occiput anterior position confirmed by ultrasonography 1 hour after randomisation. RESULTS: One hour after the randomisation, 35 of 203 (17%) fetuses were diagnosed as being in the occiput anterior position in the intervention group compared with 24 of 209 (12%) in the control group. This difference was not statistically significant (relative risk 1.50; 95% CI 0.93-2.43; P = 0.13). The change in the evaluation of comfort between the randomisation and 15 minutes after showed an improvement in 70 and 39 women, no change in 82 and 78 women and a decrease in 56 and 86 women in the intervention and control groups, respectively (P = 0.02). CONCLUSIONS: This study could not demonstrate a benefit of the hands and knees position to correct the occiput posterior position of the fetus during the first stage of labour, but the women reported an increase in their comfort level. TWEETABLE ABSTRACT: Hands and knees position does not facilitate rotation into occiput anterior but increases the comfort level of women.

RESUMEN

Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-ToF MS) has been introduced in clinical routine microbiology laboratories. For the rapid diagnosis of urinary tract infections, culture-independent methods prior MALDI-mediated identification have been described. Here, we describe a comparison of three of these methods based on their performance of bacterial identification and their potential as a routine tool for microbiology labs : (i) differential centrifugation, (ii) urine filtration and (iii) a 5-h bacterial cultivation on solid culture media. For 19 urine samples, all methods were directly compared and correct bacterial species identification by MALDI was used as performance indicator. A higher percentage of correct MALDI identification was obtained after filtration (78.9 %) and the growth-based method (84.2 %) as compared to differential centrifugation (68.4 %). Additional testing of 76 mono-microbial specimens (bacteriuria > 10(5) CFU/mL) confirmed the good performance of short growth with a 90.8 % correct MALDI score, with a potentially better fit to the routine workflow of microbiology labs.

RESUMEN

OBJECTIVE: To evaluate the effectiveness of 200 mg of daily vaginal natural progesterone to prevent preterm birth in women with preterm labour. DESIGN: Multicentre, randomised, double-blind, placebo-controlled trial. SETTING: Twenty-nine centres in Switzerland and Argentina. POPULATION: A total of 385 women with preterm labour (24(0/7) to 33(6/7) weeks of gestation) treated with acute tocolysis. METHODS: Participants were randomly allocated to either 200 mg daily of self-administered vaginal progesterone or placebo within 48 hours of starting acute tocolysis. MAIN OUTCOME MEASURES: Primary outcome was delivery before 37 weeks of gestation. Secondary outcomes were delivery before 32 and 34 weeks, adverse effects, duration of tocolysis, re-admissions for preterm labour, length of hospital stay, and neonatal morbidity and mortality. The study was ended prematurely based on results of the intermediate analysis. RESULTS: Preterm birth occurred in 42.5% of women in the progesterone group versus 35.5% in the placebo group (relative risk [RR] 1.2; 95% confidence interval [95% CI] 0.93-1.5). Delivery at <32 and <34 weeks did not differ between the two groups (12.9 versus 9.7%; [RR 1.3; 95% CI 0.7-2.5] and 19.7 versus 12.9% [RR 1.5; 95% CI 0.9-2.4], respectively). The duration of tocolysis, hospitalisation, and recurrence of preterm labour were comparable between groups. Neonatal morbidity occurred in 44 (22.8%) cases on progesterone versus 35 (18.8%) cases on placebo (RR: 1.2; 95% CI 0.82-1.8), whereas there were 4 (2%) neonatal deaths in each study group. CONCLUSION: There is no evidence that the daily administration of 200 mg vaginal progesterone decreases preterm birth or improves neonatal outcome in women with preterm labour.

RESUMEN

The presence of uterine contractions and a short cervix at less than 37 weeks of gestation (preterm labor) is an important risk factor for a preterm birth. Currently, there is not treatment able to reduce the risk of preterm birth in this high risk group of women. Vaginal progesterone has been shown to be effective in reducing the risk of preterm birth in asymptomatic women with a prior preterm birth and in women with a short cervix, measured by vaginal ultrasound before 24 weeks of gestation. Unfortunately, vaginal progesterone has not been shown to be efficacious in women with preterm labor. A recent clinical trial has shown that it can even be deleterious in this group of women.

RESUMEN

In 2005, a new sibling species of Aspergillus fumigatus was discovered: Aspergillus lentulus. Both species can cause invasive fungal disease in immune-compromised patients. The species are morphologically very similar. Current techniques for identification are PCR-based or morphology-based. These techniques are labour-intense and not sufficiently discriminatory. Since A. lentulus is less susceptible to several antifungal agents, it is important to correctly identify the causative infectious agent in order to optimize antifungal therapy. In this study we determined whether Raman spectroscopy and/or MALDI-TOF MS were able to differentiate between A. lentulus and A. fumigatus. For 16 isolates of A. lentulus and 16 isolates of A. fumigatus, Raman spectra and peptide profiles were obtained using the Spectracell and MALDI-TOF MS (VITEK MS RUO, bioMérieux) respectively. In order to obtain reliable Raman spectra for A. fumigatus and A. lentulus, the culture medium needed to be adjusted to obtain colourless conidia. Only Raman spectra obtained from colourless conidia were reproducible and correctly identified 25 out of 32 (78 %) of the Aspergillus strains. For VITEK MS RUO, no medium adjustments were necessary. Pigmented conidia resulted in reproducible peptide profiles as well in this case. VITEK MS RUO correctly identified 100 % of the Aspergillus isolates, within a timeframe of approximately 54 h including culture. Of the two techniques studied here, VITEK MS RUO was superior to Raman spectroscopy in the discrimination of A. lentulus from A. fumigatus. VITEK MS RUO seems to be a successful technique in the daily identification of Aspergillus spp. within a limited timeframe.

RESUMEN

AIMS: Housing First (HF), a recovery-oriented approach, was proven effective in stabilising housing situations of homeless individuals with severe mental disorders, yet had limited effectiveness on recovery outcomes on a short-term basis compared to standard treatment. The objective was to assess the effects of the HF model among homeless people with high support needs for mental and physical health services on recovery, housing stability, quality of life, health care use, mental symptoms and addiction issues on 4 years of data from the Un Chez Soi d'Abord trial. METHODS: A multicentre randomised controlled trial was conducted from August 2011 to April 2018 with intent-to-treat analysis in four French cities: Lille, Marseille, Paris and Toulouse. Participants were homeless or precariously-housed patients with a DSM-IV-TR diagnosis of bipolar disorder or schizophrenia. Two groups were compared: the HF group (n = 353) had immediate access to independent housing and support from the assertive community treatment team; the Treatment-As-Usual (TAU) group (n = 350) had access to existing support and services. Main outcomes were personal recovery (Recovery Assessment Scale (RAS) scale), housing stability, quality of life (S-QoL), global physical and mental status (Medical Outcomes Study 36-item Short Form Health Survey (SF-36)), inpatient days, mental symptoms (Modified Colorado Symptom Index (MCSI)) and addictions (Mini International Neuropsychiatric Interview (MINI) and Alcohol Use Disorders Identification Test (AUDIT)). Mixed models using longitudinal and cluster designs were performed and adjusted to first age on the street, gender and mental disorder diagnosis. Models were tested for time × group and site × time interactions. RESULTS: The 703 participants [123 (18%) female] had a mean age of 39 years (95% CI 38.0-39.5 years). Both groups improved RAS index from baseline to 48 months, with no statistically significant changes found between the HF and TAU groups over time. HF patients exhibited better autonomy (adjusted ß = 2.6, 95% CI 1.2-4.1) and sentimental life (2.3, 95% CI 0.5-4.1), higher housing stability (28.6, 95% CI 25.1-32.1), lower inpatient days (-3.14, 95% CI -5.2 to -1.1) and improved SF-36 mental composite score (-0.8, 95% CI -1.6 to -0.1) over the 4-year follow-up. HF participants experienced higher alcohol consumption between baseline and 48 months. No significant differences were observed for self-reported mental symptoms or substance dependence. CONCLUSION: Data at 4 years were consistent with 2-year follow-up data: similar improvement in personal recovery outcomes but higher housing stability, autonomy and lower use of hospital services in the HF group compared to the TAU group, with the exception of an ongoing alcohol issue. These sustained benefits support HF as a valuable intervention for the homeless patients with severe mental illness. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01570712.

RESUMEN

AIMS: Many people who are homeless with severe mental illnesses are high users of healthcare services and social services, without reducing widen health inequalities in this vulnerable population. This study aimed to determine whether independent housing with mental health support teams with a recovery-oriented approach (Housing First (HF) program) for people who are homeless with severe mental disorders improves hospital and emergency department use. METHODS: We did a randomised controlled trial in four French cities: Lille, Marseille, Paris and Toulouse. Participants were eligible if they were 18 years or older, being absolutely homeless or precariously housed, with a diagnosis of schizophrenia (SCZ) or bipolar disorder (BD) and were required to have a high level of needs (moderate-to-severe disability and past hospitalisations over the last 5 years or comorbid alcohol or substance use disorder). Participants were randomly assigned (1:1) to immediate access to independent housing and support from the Assertive Community Treatment team (social worker, nurse, doctor, psychiatrist and peer worker) (HF group) or treatment as usual (TAU group) namely pre-existing dedicated homeless-targeted programs and services. Participants and interviewers were unmasked to assignment. The primary outcomes were the number of emergency department (ED) visits, hospitalisation admissions and inpatient days at 24 months. Secondary outcomes were recovery (Recovery Assessment Scale), quality of life (SQOL and SF36), mental health symptoms, addiction issues, stably housed days and cost savings from a societal perspective. Intention-to-treat analysis was performed. RESULTS: Eligible patients were randomly assigned to the HF group (n = 353) or TAU group (n = 350). No differences were found in the number of hospital admissions (relative risk (95% CI), 0.96 (0.76-1.21)) or ED visits (0.89 (0.66-1.21)). Significantly less inpatient days were found for HF v. TAU (0.62 (0.48-0.80)). The HF group exhibited higher housing stability (difference in slope, 116 (103-128)) and higher scores for sub-dimensions of S-QOL scale (psychological well-being and autonomy). No differences were found for physical composite score SF36, mental health symptoms and rates of alcohol or substance dependence. Mean difference in costs was €-217 per patient over 24 months in favour of the HF group. HF was associated with cost savings in healthcare costs (RR 0.62(0.48-0.78)) and residential costs (0.07 (0.05-0.11)). CONCLUSION: An immediate access to independent housing and support from a mental health team resulted in decreased inpatient days, higher housing stability and cost savings in homeless persons with SCZ or BP disorders.

RESUMEN

AIMS: The objectives of the present study were to determine the rates and associated factors of (i) MDD, (ii) antidepressant prescription and (iii) MDD non-remission in homeless subjects with bipolar disorder (BD) or schizophrenia (SZ). METHODS: This multicenter study was conducted in 4 French cities. MDD was defined with the section L of the MINI. Unremitted MDD was defined by current antidepressant treatment and current MDD. RESULTS: 700 subjects, mean aged 38 years and 82.5% men were included: 55.4% were diagnosed with MDD but only 10.4% were administered antidepressants. Violent victimization in the past 6 months, alcohol use disorder and current substance abuse disorder were associated with increased rates of MDD. 71.2% antidepressant-treated subjects were unremitted. BD diagnosis and substance abuse disorder were found to be associated with increased risk of unremitted MDD. BD-MDD patients were found to be twice more frequently administered antidepressants than SZ-MDD ones, however the non-remission rates were higher in BD subjects compared to SZ. No antidepressant class and no specific antipsychotic or mood stabilizer has been associated with higher or lower rates of remitted MDD. CONCLUSION: MDD seems to be highly prevalent, underdiagnosed and undertreated in BD and SZ homeless subjects. Beyond antidepressants, add-on strategies including complementary agents, lithium, lamotrigine/carbamazepine or anti-inflammatory drugs and the specific care of alcohol and substance use disorders may be recommended to improve the prognosis of this specific population in addition to other interventions including housing and resocialization. Violent victimization is also frequent and should be specifically prevented in this vulnerable population.

RESUMEN

BACKGROUND: Guidelines have been edited for the treatment of schizophrenia (SZ) and bipolar disorders (BD). Background regimen is currently recommended for both illnesses (antipsychotic drug for SZ and mood stabilizer for BD). The recommendations are less clear for major depression in these disorders. Long-term anxiolytic and hypnotic prescriptions may have potential side effects and should be withdrawn as soon as possible. OBJECTIVE: The aim of this study was to investigate the prevalence and associated factors of Potentially Inappropriate Psychotropic drugs (PIP) in a large multicenter sample of Homeless Schizophrenia (SZ) and Bipolar Disorder (BD) (HSB) patients. METHODS: This multicenter study was conducted in 4 French cities: Lille, Marseille, Paris and Toulouse. PIP was defined by at least one item among: (i) absence of background regimen (antipsychotic for SZ or mood stabilizer for BD), (ii) absence of antidepressant for major depressive disorder and (iii) daily long-term anxiolytic or (iv) hypnotic prescription. RESULTS: Overall, 703 HSB patients, mean aged 38 years and 82.9% men were included, 487 SZ (69.3%) and 216 BD (30.7%). 619 (88.4%) of the patients reported at least one PIP. 386 (54.9%) patients had an inappropriate background regimen prescription (209(43.4%) of SZ had no antipsychotic prescription and 177(81.9%) of BD no mood stabilizer), 336 (48%) had an inappropriate antidepressant prescription (with no significant difference between SZ and BD), 326 (46.4%) had an inappropriate prescription of anxiolytics and 107 (15.2%) had an inappropriate prescription of hypnotics. 388(55%) of the subjects were diagnosed with major depression but only 52(13%) of them were administered antidepressants. In multivariate analysis, PIP was associated with bipolar disorder diagnosis (aOR = 4.67 [1.84-11.89], p = 0.001), current major depressive disorder (aOR = 27.72 [9.53-80.69], p < 0.0001), lower rate of willingness to ask for help (aOR = 0.98[0.96-0.99], p = 0.001). Potentially inappropriate background regimen prescription was associated with bipolar disorder diagnosis (aOR = 6.35 [3.89-10.36], p < 0.0001), lower willingness to ask for help (aOR = 0.99[0.98-0.99], p = 0.01) and lack of lifetime history of psychiatric care (aOR = 0.30[0.12-0.78], p = 0.01). Inappropriate antidepressant prescription was associated with antisocial personality disorder (aOR = 1.58 [1.01-2.48], p = 0.04) and current substance use disorder (aOR = 2.18[1.48-3.20], p < 0.0001). CONCLUSION: The present findings suggest that almost 9 on 10 HSB subjects may receive a PIP including inappropriate prescriptions or absence of appropriate prescription. Bipolar disorder and/or major depression should be targeted in priority and treated with mood stabilizers and/or antidepressants in this population, while anxiolytics and hypnotics should be withdrawn as much as possible. Major depression should be particularly explored in subjects with comorbid antisocial personality disorder and substance use disorder. The psychiatric care has been associated with better appropriate psychotropic prescriptions and should be reinforced in this population.

RESUMEN

OBJECTIVE: The aim of this study was to investigate the prevalence and associated factors of physical pain in a large multicenter sample of Homeless Schizophrenia and Bipolar (HSB) patients. METHODS: This multicenter study was conducted in 4 French cities: Lille, Marseille, Paris and Toulouse. Pain was measured by EQ5D-3 L questionnaire with no specified period or location. In addition, sociodemographic information, duration of homelessness, illness severity using the Modified Colorado Symptom Index (MCSI) and drug information were collected. RESULTS: Overall, 655 HSB patients, mean age 38.8 years and 82.6% men were included, 448 (68.9%) were diagnosed with schizophrenia and 202 (31.1%) with bipolar disorder. More than half patients (N = 337, 51.5%) reported moderate to extreme physical pain while only 2.7% were administered analgesic drugs. In the multivariate analysis, self-reported moderate to extreme physical pain was associated with antidepressant consumption (adjusted odd ratio aOR = 2.56[1.25;5.26], p = .01), female gender (aOR = 1.72[1.03;2.86], p = .04), bipolar disorders (vs. schizophrenia) (aOR = 1.81[1.19;2.77], p = .006), older age (aOR = 1.03 [1.01;1.05], p = .01), with higher MCSI psychotic score (a0R = 1.04[1.01;1.06],p = .002), independently of the number of days in the street during the last 180 days, MCSI depression score, alcohol and substance use disorders, psychotropic drugs and analgesic treatments. No association with education level, antipsychotics, mood stabilizers, anxiolytic, hypnotic or medication adherence was found (all p > .05). CONCLUSION: Physical pain was highly reported in homeless patients with severe mental illness with insufficient care. Physical pain should be systematically explored and treated in this population. Bipolar disorders, antidepressant consumption and female gender may be targeted in priority. Age and psychotic symptomatology were found to influence self-reported pain in a marginal way.

RESUMEN

OBJECTIVE: The aim of this study was to investigate the factors associated with violent behavior in a large multicenter sample of Homeless Schizophrenia (SZ) and Bipolar Disorder (BD) (HSB) subjects. METHODS: This multicenter study was conducted in 4 French cities: Lille, Marseille, Paris and Toulouse. Violent behavior was defined by at least one episode of verbal or physical violence in the last 6 months. RESULTS: Overall, 675 HSB patients, mean aged 38 years and 82.5% men were included, 458 SZ (68.4%) and 212 BD (31.6%). During the 6 months before evaluation, 213 (34.3%) committed at least one physical or verbal violence. In multivariate analysis, violence has been associated with younger age (aOR = 0.96[0.94-0.99], p = .001), number of nights in the street (aOR = 1.01[1.01-1.01]), BD diagnosis (aOR = 1.63[1.01-2.65], p = .04), higher current illness severity (CGI score) (aOR = 1.32[1.07-1.64], p = .01), higher rates of current manic episode (aOR = 2.24[1.32-3.81], p = .002), current alcohol use disorder (aOR = 2.05 [1.33-3.15], p = .001), antisocial personality disorder (aOR = 2.51[1.55-4.07], p < .001) and with antidepressant consumption (aOR = 2.01[1.01-4.04], p = .04). No specific antipsychotic or mood stabilizer has been associated with decreased rates of violent behavior, however clozapine, lithium and carbamazepine remained poorly prescribed. CONCLUSION: In case of violent behavior in HSB subjects, clinicians should focus in priority on the treatment of mania, antidepressant iatrogenic effect and alcohol use disorder by pharmacological and non-pharmacological treatments. Clozapine, lithium and carbamazepine should be chosen as the treatments of reference in this population but may be hard to manage in some cases. The current clinical trial number is NCT01570712.

RESUMEN

INTRODUCTION: Chronic insufficiency alters homeostasis, in part due to endothelial inflammation. Plasminogen activator inhibitor-1 (PAI-1) is increased in renal disease, contributing to vascular damage. We assessed PAI-1 activity and PAI-1 4G/5G polymorphism in hemodialysis (HD) subjects and any association between thrombotic vascular access (VA) events and PAI-1 polymorphism. METHODS: Prospective, observational study in 36 HD patients: mean age: 66.6 +/- 12.5 yr, males n=26 (72%), time on HD: 28.71 +/- 22.45 months. Vascular accesses: 10 polytetrafluoroethylene grafts (PTFEG), 22 arteriovenous fistulae (AVF), four dual lumen catheters (CAT). Control group (CG): 40 subjects; mean age: 60.0 +/- 15 yrs, males n=30 (75%). Group A (GA): thrombotic events (n=12), and group B (GB): No events (n=24). Groups were no different according to age (69.2 +/- 9.12 vs. 65.3 +/- 14.5 yrs), gender (males: 7; 58.3% vs. 18; 81.8%), time on HD (26.1 +/- 14.7 vs. 30.1 +/- 38.7 months), causes of renal failure. Time to follow-up for access thrombosis: 12 months. RESULTS: PAI-1 levels in HD: 7.21 +/- 2.13 vs. CG: 0.42 +/- 0.27 U/ml (p<0.0001). PAI-1 4G/5G polymorphic variant distribution in HD: 5G/5G: 6 (17%), 4G/5G: 23 (64%); 4G/4G: 7 (19%) and in CG: 5G/5G: 14 (35%); 4G/5G: 18 (45%); 4G/4G: 8 (20%). C-reactive protein (CRP) in HD: 24.5 +/- 15.2 mg/L vs. in CG 2.3 +/- 0.2 mg/L (p<0.0001). PAI-1 4G/5G variants: GA: 5G/5G: 3; 4G/5G: 8; 4G/4G: 1; GB: 5G/5G: 3; 4G/5G: 15; 4G/4G: 6. Thrombosis occurred in 8/10 patients (80%) with PTFEG, 3/22 (9%) in AVF, and 1/4 (25%) in CAT. Among the eight PTFEG patients with thrombosis, seven were PAI 4G/5G. CONCLUSIONS: PAI-1 levels were elevated in HD patients, independent of their polymorphic variants, 4G/5G being the most prevalent variant. Our data suggest that in patients with PTFEG the 4G/5G variant might be associated with an increased thrombosis risk.

RESUMEN

OBJECTIVES: To describe the maternal and foetal outcomes of an occiput posterior foetal position at delivery; to evaluate predictive factors of anterior rotation during labour. METHODS: Descriptive retrospective analysis of a cohort of 439 women with foetuses in occiput posterior position during labour. Logistic regression analysis to quantify the effect of factors that may favour anterior rotation. RESULTS: Most of foetuses (64%) do an anterior rotation during labour and 13% during the expulsive phase. The consequences of a persistent foetal occiput posterior position during delivery are a significantly increased average time of second stage labour compared to others positions (65.19minutes vs. 43.29, P=0.001, respectively); a higher percentage of caesarean sections (72.0% versus 4.7%, P<0.001) and instrumental delivery (among low-birth deliveries, 60.7% versus 25.2%, P<0.001); more frequent third-degree perineal tears (14.3% vs. 0.6%, P<0.001) and more abundant blood loss (560mL versus 344mL, P<0.001). In a multi-variable model including nulliparity, station of the presenting part and degree of flexion of the foetal head at complete dilatation, the only predictive factor independent of rotation at delivery is a good flexion of the foetal head at complete dilatation, which multiplies the anterior rotation probability by six. CONCLUSION: A good flexion of the foetal head is significantly associated with anterior rotation. Other studies exploring ways to increase anterior rotation during labour are needed to reduce the very high risk of caesarean section and instrumentation associated with the foetal occiput posterior position.

RESUMEN

STUDY DESIGN: Retrospective study. INTRODUCTION: Local infiltration analgesia is effective in many surgeries as knee arthroplasty, but the analgesic efficacy of local infiltration analgesia with ropivacaine in trauma spine surgery in T10 to L2 has not been clarified. We conducted a trial to assess the analgesic efficacy of intraoperative local infiltration analgesia (LIA) with ropivacaine. OBJECTIVE: The aim of the present study was to clarify the effect of intraoperative local infiltration analgesia with ropivacaine on postoperative pain for patients undergoing thoracolumbar junction fracture surgery. METHODS: In a retrospective study, in 76 patients undergoing spine surgery for thoracolumbar junction fracture, 20ml of ropivacaine 7.5% (n R group=38) was infiltrated using a systematic technique, or no infiltration was realized (n M group=38). We assessed postoperative pain with Visual Analogue Scale (VAS) and morphine consumption in the 24 first hours. RESULTS: VAS pain score upon awakening and at 2hours postoperatively were significantly lower in the ropivacaine group (P=0.01 and P=0.002). Rescue opioid requirement during the 24 first hours were about 50% lower in the ropivacaine group (P=0.01). No local or systemic side effects were observed. CONCLUSION: Intraoperative LIA with ropivacaine in thoracolumbar junction fracture surgery may have an analgesic effect in postoperative pain control (24hours) with a reduction of VAS and morphine consumption.
