3-year incidence and predictors of metabolic syndrome in schizophrenia in the national FACE-SZ cohort

AIMS

Metabolic Syndrome (MetS) is a major health epidemic of Western countries and patients with schizophrenia is a particularly vulnerable population due to lifestyle, mental illness and treatment factors. However, we lack prospective data to guide prevention. The aim of our study is then to determine MetS incidence and predictors in schizophrenia.

METHOD

Participants were recruited in 10 expert centers at a national level and followed-up for 3 years. MetS was defined according to the International Diabetes Federation criteria. Inverse probability weighting methods were used to correct for attrition bias.

RESULTS

Among the 512 participants followed-up for 3 years, 77.9% had at least one metabolic disturbance. 27.5% were identified with MetS at baseline and excluded from the analyses. Among the rest of participants (N = 371, mean aged 31.2 (SD = 9.1) years, with mean illness duration of 10.0 (SD = 7.6) years and 273 (73.6%) men), MetS incidence was 20.8% at 3 years and raised to 23.6% in tobacco smokers, 29.4% in participants receiving antidepressant prescription at baseline and 42.0% for those with 2 disturbed metabolic disturbances at baseline. Our multivariate analyses confirmed tobacco smoking and antidepressant consumption as independent predictors of MetS onset (adjusted odds ratios (aOR) = 3.82 [1.27-11.45], p = 0.016, and aOR = 3.50 [1.26-9.70], p = 0.0158). Antidepressant prescription predicted more specifically increased lipid disturbances and paroxetine was associated with the highest risk of MetS onset.

CONCLUSION

These results are an alarm call to prioritize MetS prevention and research in schizophrenia. We have listed interventions that should be actively promoted in clinical practice.

The impact of parent history of severe mental illness on schizophrenia outcomes: results from the real-world FACE-SZ cohort

Parent history of severe mental illness (PHSMI) may have long-term consequences in adult offspring due to genetic and early environmental factors in preliminary studies. To compare the outcomes associated in subjects with PHSMI to those in patients without PHSMI. The participants with schizophrenia and schizoaffective disorders were recruited in the ongoing FACE-SZ cohort at a national level (10 expert centers) and evaluated with a 1-day-long standardized battery of clinician-rated scales and patient-reported outcomes. PHSMI was defined as history of schizophrenia or bipolar disorders in at least one parent and was included as explanatory variable in multivariate models. Of the 724 included patients, 78 (10.7%) subjects were classified in the PHSMI group. In multivariate analyses, PHSMI patients had a better insight into schizophrenia and the need for treatment and reported more often childhood trauma history compared to patients without PHSMI. More specifically, those with paternal history of SMI reported more severe outcomes (increased childhood physical and emotional abuses, comorbid major depression and psychiatric hospitalizations). PHSMI is associated with increased risk of childhood trauma, major depressive disorder and psychiatric hospitalization and better insight in individuals with schizophrenia. Specific public health prevention programs for parents with SMI should be developed to help protect children from pejorative psychiatric outcomes. PHSMI may also explain in part the association between better insight and increased depression in schizophrenia.

Stability of Extemporaneously Prepared Hydroxycarbamide Oral Suspensions

Hydroxycarbamide, available as tablets, is a pharmacological agent for fetal hemoglobin induction such as sickle cell anemia. The need for alternative dosage form options for patients unable to take tablets led hospital pharmacies to prepare solutions and suspensions. The objective of this study was to determine the stability of hydroxycarbamide in Ora-Plus in combination with either Ora-Sweet or Ora-Sweet SF, Ora-Blend, or Ora-Blend SF suspending agents. The studied samples were compounded into 100-mg/mL suspensions and stored in 60-mL amber glass bottles at room (22°C to 25°C) or refrigerated (4°C to 8°C) temperature. Samples were assayed at each time point out to 120 days by a stability-indicating high-performance liquid chromatography method. The samples were examined for any change in color, odor, visual microbiology, and pH on initial and final day of analysis. At least 90% of hydroxycarbamide concentration remained in all suspensions at the end of the 120-day study period in both conditions. There was no appreciable change in color, odor, or taste. The pH values of suspensions stored at 25°C changed by at least 1 unit at the end of the study period. Based on the data collected, the beyond-use date of these suspensions is 120 days when stored in 60-mL amber glass bottles at both temperature storage conditions.

Stability study of oral pediatric idebenone suspensions

Adapted forms for administration to infants are limited. The proposed study was performed to propose oral liquid formulations of idebenone in Ora-Plus and either Ora-Sweet or Ora-Sweet SF, Ora-Blend, Ora-Blend SF and Inorpha. Each formulation was stored in 30 ml amber glass bottle at 5 or 25 °C for 90 days. Idebenone contents in these suspensions, determined by a stability-indicating high-performance liquid chromatography method, remained stable at least 90 days in Inorpha when stored at the two temperatures. In Ora-Blend, the stability was estimated at 14 days and in other suspensions at 20 days at the two temperatures. After 90 days storage, the pH of Ora-Plus and Ora-Sweet or Ora-Sweet SF changed between -0.10 and -0.25 units. For others suspensions, the pH changes were not significant (< -0.09 unit). No change was observed in color, odor or visual microbiology. To conclude, we recommended the use of idebenone in Inorpha vehicle stable for at least 90 days at 25 °C.

Description of Methicillin-resistant Staphylococcus pseudintermedius from canine pyoderma in Minas Gerais state, Brazil

Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is of worldwide concern in veterinary medicine. The identification of resistant strains is necessary for proper treatment and the prevention of its propagation among animals. This study aimed to identify S. pseudintermedius isolated from canine pyoderma and evaluate their resistance profiles. Lesions from 25 dogs with pyoderma were sampled. Bacterial isolates were subjected to phenotypic and genotypic analysis for identification of the causative agent. S. pseudintermedius isolates were subjected to SmaI macrorestriction analysis and PFGE for genetic grouping, and PCR to identify the presence of the mecA gene. Their resistance profiles against 12 antimicrobials were also assessed. According to the microbiological analysis, 70 of the 75 isolates obtained were S. pseudintermedius. The isolates presented PFGE patterns, with similarity varying between 84.6 and 100%, and were grouped into 19 clusters. Despite a high frequency of mecA-positive isolates (66 out 70), only 12 presented resistances to oxacillin. Multi-resistance was identified in 29 isolates. The high frequency of MRSP isolated in this study highlights the relevance of identifying resistant strains to lead proper clinical treatment.

Canine hypospadias is a rare condition that can occur in male and female dogs. Affected animals may present signs of urinary incontinence, recurrent urinary tract infections, periurethral dermatitis or can remain asymptomatic. Periurethral hypospadias in a 14-week-old mongrel dog and its surgical repair are addressed.

Intestine-specific regulation of PPARalpha gene transcription by liver X receptors

Liver X receptor-alpha (LXRalpha) and LXRbeta are ligand-activated transcription factors belonging to the nuclear receptor superfamily. They have been identified as key players in cholesterol homeostasis and lipid and glucose metabolism as well as immune and inflammatory responses. In the small intestine, LXRs have been shown not only to regulate cholesterol absorption and excretion but also to promote high-density lipoprotein biogenesis via the ATP-binding cassette A1 signaling pathway. Here, using gene expression assays, we identified PPARalpha as an intestine-specific LXR target gene. Chronic administration of LXR synthetic agonists led to a significant increase of PPARalpha mRNA levels in the small intestine but not in the liver. In addition, this specific PPARalpha gene up-regulation occurred in the duodenum, jejunum, and ileum in a dose-dependent manner and translated at the protein level as demonstrated by Western blot analysis. Furthermore, PPARalpha gene induction was completely abolished in LXR-deficient mice. Finally, the physiological relevance of LXR-mediated PPARalpha up-regulation in the small intestine was assessed in PPARalpha-deficient mice. Administration of a synthetic LXR agonist to wild-type mice led to the induction of several PPARalpha target genes including PDK4 and CPT1. Those effects were completely abolished in PPARalpha-deficient mice, demonstrating the biological relevance of this LXR-PPARalpha transcriptional cascade. Taken together, these results demonstrate that PPARalpha is an intestine-specific LXR target gene and suggest the existence of a transcriptional cross talk between those members of the nuclear receptor superfamily.

Trance and shamanism: what's in a name?

This article considers the implications of the definitions and typologies of trance and shamanism for the development and testing of cross-cultural hypotheses through a review of definitions, typologies, and use of key terms and related concepts in anthropology. Authors vary widely in their definitions and applications of terms: some uses are based on reasoned criteria, others on traditional practice; some establish typologies, others prefer continua. Classifications range from narrow and highly specific to broad and inclusive coverage. Some restrict the usage to traditional societies, while others seek applications to Western phenomena, whether faith healers and mediums, or poets, such as Walt Whitman. The concept of control, with a variety of meanings assigned to it, emerges as a significant variable in the comparative study of "trance" and "shamanism" as these terms are used by different authors in widely different manners.
