Birth weight and obstetric complications determine age at onset in first episode of psychosis. J Psychiatr Res 2015; 65:108-14. [PMID: 25890850 DOI: 10.1016/j.jpsychires.2015.03.018] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2015] [Revised: 03/12/2015] [Accepted: 03/20/2015] [Indexed: 11/26/2022]
Abstract
BACKGROUND Earlier age at onset of psychosis (AOP) has been associated with poor social adjustment and clinical outcome. Genetic and environmental factors such as obstetric complications, parental history of psychosis, advanced paternal age at time of birth, low birth weight and gestational age, and use of drugs have been described as bringing AOP forward. This study aims to evaluate the relationship between AOP and these factors in a sample of first episode of psychosis (FEP) patients. METHODS Clinical and sociodemographic data, age at FEP, age of parents at birth, parental history of psychosis, drug-use habits of the mother during pregnancy and of the patient before psychotic onset, and Lewis and Murray obstetric complication scale were obtained from 90 patients with FEP. Statistical analysis was performed by means of Pearson correlations, Chi-square tests, Student T-test analyses and a linear regression model using SPSS version 22. RESULTS Pre-eclampsia, need for incubator at birth, use of forceps, parental history of psychosis, and low birth weight were associated with an earlier AOP. Use of forceps and birth weight are the variables which best predict AOP in FEP. Stimulant drugs, which were mostly used together with cannabis and cocaine, were the only substances associated with an earlier AOP. CONCLUSIONS Our findings are consistent with previous study results and underline the role of the prenatal period in the development of psychosis and the importance of careful monitoring of pregnancy and delivery, especially in cases with familial history.

Abstract
We describe the design, construction, and characterization of a scalable microfluidic platform that allows continuous monitoring of biofilm proliferation under shear stress conditions. Compared to other previous end-point assay studies, our platform offers the advantages of integration into multiple environments allowing simultaneous optical microscopy and impedance spectroscopy measurements. In this work we report a multi-parametric sensor that can monitor the growth and activity of a biofilm. This was possible by combining two interdigitated microelectrodes (IDuEs), and punctual electrodes to measure dissolved oxygen, K+, Na+ and pH. The IDuE has been optimized to permit sensitive and reliable impedance monitoring of Staphylococcus aureus V329 growth with two- and four-electrode measurements. We distinguished structural and morphological changes on intact cellular specimens using four-electrode data modeling. We also detected antibiotic mediated effects using impedance. Results were confirmed by scanning electrode microscopy and fluorescence microscopy after live/dead cell staining. The bacitracin mediated effects detected with impedance prove that the approach described can be used for guiding the development of novel anti-biofilm agents to better address bacterial infection.

Abstract
BACKGROUND We report a case of pyoderma gangrenosum (PG) associated with a complication comprising ascending aortic dissection (neutrophilic aortitis) in a setting of rheumatoid arthritis (RA). PATIENTS AND METHODS A 79-year-old female patient was hospitalized in late 2009 for vegetating PG. Treatment with general steroids followed by colchicine and topical steroids resulted in complete healing of skin lesions. During hospitalization, the patient presented dissection of the ascending part of the aorta, for which emergency surgery proved effective. Histological examination of the excised tissue revealed diffuse neutrophilic aortitis. Diagnoses of Takayashu's disease and of lupus were ruled out. A chest CT scan showed interstitial lung disease with mild lymphocytosis in the bronchoalveolar fluid, but with no isolated pathogenic organisms. Relapse of skin lesions occurred 3 and 4 years later, associated with the development of RA, and worsening of the interstitial lung disease was noted in a scan carried out it in 2013, following which stabilization was observed in April 2014. There was no recurrence of the PG lesions. CONCLUSION To our knowledge, no other cases involving association of neutrophilic aortitis with PG and RA has been published to date. The literature describes the emergence of the concept of systemic neutrophilic dermatoses, and this notion is reinforced by the presence of a cutaneous and aortic site of the neutrophilic disease in a single patient.

Abstract
Slow-twitch (type 1) skeletal muscle fibers have markedly greater mitochondrial content than fast-twitch (type 2) fibers. Accordingly, we sought to determine whether the dielectric properties of these two fiber types differed, consistent with their distinct intracellular morphologies. The longitudinal and transverse dielectric spectrum of the ex vivo rat soleus (a predominantly type 1 muscle) and the superficial layers of rat gastrocnemius (predominantly type 2) (n = 15) were measured in the 1 kHz-10 MHz frequency range and modeled to a resistivity Cole-Cole function. Major differences were especially apparent in the dielectric spectrum in the 1 to 10 MHz range. Specifically, the gastrocnemius demonstrated a well-defined, higher center frequency than the soleus muscle, whereas the soleus muscle showed a greater difference in the modeled zero and infinite resistivities than the gastrocnemius. These findings are consistent with the fact that soleus tissue has larger and more numerous mitochondria than gastrocnemius. Evaluation of tissue at high frequency could provide a novel approach for assessing intracellular structure in health and disease.
