Monocyte Transcriptional Profiling Highlights a Shift in Immune Signatures Over the Course of Illness in Schizophrenia.

With advanced understanding of the intricate interplay between the immune and central nervous systems in neurological and neuropsychiatric illness, there is renewed interest in the potential contribution of immune dysregulation to the development and progression of schizophrenia. To inform this line of inquiry requires a more nuanced understanding of specific immune changes throughout the course of illness. Here, we utilized a genome-wide sequencing approach to transcriptionally profile circulating monocytes in participants with chronic schizophrenia.

Examining the effects of the histone methyltransferase inhibitor BIX-01294 on histone modifications and gene expression in both a clinical population and mouse models.

Schizophrenia has been consistently characterized by abnormal patterns of gene down-regulation, increased restrictive chromatin assemblies, and reduced transcriptional activity. Histone methyltransferase (HMT) mRNA and H3K9me2 levels are elevated in postmortem brain and peripheral blood cells of persons with schizophrenia. Moreover, this epigenomic state likely contributes to the disease, as HMT levels correlate with clinical symptomatology.

Risperidone effects on heterochromatin: the role of kinase signaling.

Epigenetic effects of anti-psychotic medications are poorly understood. We have appropriated a model whereby heterochromatin is established through 24- or 48-h lipopolysaccharide (LPS) treatment, and tested the epigenetic effects of risperidone along the adenylyl cyclase/protein kinase A (AC/PKA) pathway in human liposarcoma cells that express the LPS-sensitive Toll-like receptor (TLR)-4. Human SW872 cells were cultured with LPS and mRNA expression levels and epigenetic modifications of dimethylated lysine 9 of histone 2 (H3K9me2), geterochromatin protein 1γ (HP1γ) and phospho-H3S10 at promoters of interleukin (IL)-6, tumor necrosis factor (TNF)-α and IL1β were measured.

Traumagenics: At the intersect of childhood trauma, immunity and psychosis.

Early childhood trauma, including physical, sexual or emotional abuse, neglect, harm or threat of harm, is associated with adulthood dysregulation of the immune system. Trauma can induce chronic immune system activation. Associations between a chronic pro-inflammatory state and schizophrenia are an enduring finding of psychiatry, with elevated cytokine concentrations correlated with psychotic symptom severity.

The JAK-STAT1 transcriptional signature in peripheral immune cells reveals alterations related to illness duration and acuity in psychosis.

Multiple lines of inquiry demonstrate alterations to immune function in psychosis. Clinically, this is reflected by elevated proinflammatory cytokines in serum, indicating activation of circulating immune cells. Data from isolated cells in clinical populations support the presence of altered activity of pertinent intracellular signaling pathways.

Perioperative interventions in pelvic organ prolapse surgery.

Background: Pelvic organ prolapse (POP) affects as many as 50% of parous women, with 14% to 19% of women undergoing a surgical correction. Although surgery for the treatment of POP is common, limited supportive data can be found in the literature regarding the preoperative and postoperative interventions related to these procedures. The main goal of perioperative interventions is to reduce the rate of adverse events while improving women's outcomes following surgical intervention for prolapse.

C4A mRNA expression in PBMCs predicts the presence and severity of delusions in schizophrenia and bipolar disorder with psychosis.

Altered immune function is an established finding in psychotic disorders such as schizophrenia and bipolar disorder with psychosis, though its role in their development and progression remains to be understood. Evidence suggests altered JAK-STAT1 pathway activity in peripheral blood cells from participants with schizophrenia compared to controls. Activation of this pathway leads to increased expression of complement component 4A (C4A), which has recently been implicated in schizophrenia.

Estrogen receptor and laminin genetic polymorphism among women with pelvic organ prolapse.

Objective: Laminin is a connective tissue component. The LAMC1 gene encodes for gamma-1 chain of laminin, which is associated with familial clustering of POP. The ERα gene which encodes for cellular estrogen receptor has also been associated with POP.

Long non-coding and endogenous retroviral RNA levels are associated with proinflammatory cytokine mRNA expression in peripheral blood cells: Implications for schizophrenia.

Recent research indicates that the expression of long non-coding and endogenous retroviral RNAs is coordinated with the activity of immune molecules often dysregulated in schizophrenia. We measured the expression of TMEVPG1, NRON, HERV-W env and HERV-W gag in blood cells from participants with schizophrenia and controls. We report that a) expression levels of these non-coding RNAs are correlated with proinflammatory cytokine mRNA expression in all participants, b) HERV-W transcripts are negatively correlated with atypical antipsychotic use in participants with schizophrenia, and c) that these RNAs are transcribed in response to proinflammatory stimuli in a THP-1 monocyte cell line.

Surgery for women with anterior compartment prolapse.

Background: To minimise the rate of recurrent prolapse after traditional native tissue repair (anterior colporrhaphy), clinicians have utilised a variety of surgical techniques.

Objectives: To determine the safety and effectiveness of surgery for anterior compartment prolapse.

Search Methods: We searched the Cochrane Incontinence Group Specialised Register, including the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In Process (23 August 2016), handsearched journals and conference proceedings (15 February 2016) and searched trial registers (1 August 2016).

Activated Phosphorylated STAT1 Levels as a Biologically Relevant Immune Signal in Schizophrenia.

Objective: Activation of STAT1 is directly downstream of the cytokine receptors that signal from specific proinflammatory cytokines known to be dysregulated in schizophrenia (SZ), such as IFNγ, IL6, IL2 and IL10, as well as hypoxia, viral/bacterial infections and peptide growth factors. If the increased cytokine protein levels repeatedly observed in SZ have biological consequences, then the measurement of pSTAT1 is a logical step forward.

Methods: Peripheral blood mononuclear cells (PBMCs) from controls (n = 13) and subjects with SZ (n = 22) were extracted using the Ficoll method.

Surgery for women with apical vaginal prolapse.

Background: Apical vaginal prolapse is a descent of the uterus or vaginal vault (post-hysterectomy). Various surgical treatments are available and there are no guidelines to recommend which is the best.

Objectives: To evaluate the safety and efficacy of any surgical intervention compared to another intervention for the management of apical vaginal prolapse.

Characterization of peripheral cannabinoid receptor expression and clinical correlates in schizophrenia.

The relationship between cannabinoid receptor signaling and psychosis vulnerability requires further exploration. The endocannabinoid signaling system is extensive, with receptors exerting regulatory functions in both immune and central nervous systems. In the brain, cannabinoid receptors (CBR) directly modulate neurotransmitter systems.

Surgical removal of a large vaginal calculus formed after a tension-free vaginal tape procedure.

Vaginal calculus is a rare disorder which has been reported in association with urethral diverticulum, urogenital sinus anomaly, bladder exstrophy and the tension-free vaginal tape (TVT) procedure. We report a 42-year-old woman who presented with persistent, intractable urinary tract infection (UTI) following a TVT procedure. Cystoscopy demonstrated an eroded tape with the formation of a bladder calculus, and the patient underwent laser cystolithotripsy and cystoscopic resection of the tape.

Transvaginal mesh or grafts compared with native tissue repair for vaginal prolapse.

Background: A wide variety of grafts have been introduced with the aim of improving the outcomes of traditional native tissue repair (colporrhaphy) for vaginal prolapse.

Objectives: To determine the safety and effectiveness of transvaginal mesh or biological grafts compared to native tissue repair for vaginal prolapse.

Search Methods: We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, ongoing trials registers, and handsearching of journals and conference proceedings (6 July 2015).

Evidence of a sex-dependent restrictive epigenome in schizophrenia.

When compared to women, men have a higher incidence of schizophrenia, with increases in negative and cognitive symptoms, and an overall poorer disease course. Schizophrenia is conceptualized as a disorder of aberrant gene transcription and regulation. Thus, epigenetics, the study of environmentally induced changes in gene regulation, could advance our understanding of the molecular underpinnings of schizophrenia.

Metabolic and inflammatory genes in schizophrenia.

Energy metabolism and immunity are characterized as abnormal in schizophrenia. Because these two systems are highly coordinated, we measured expression of prototypic obesogenic and immunogenic genes in freshly harvested PBMC from controls and participants with schizophrenia. We report significant increases in PPARγ, SREBP1, IL-6 and TNFα, and decreases in PPARα and C/EPBα and mRNA levels from patients with schizophrenia, with additional BMI interactions, characterizing dysregulation of genes relating to metabolic-inflammation in schizophrenia.

[Urogynecology: from past to future].

Over the last decade, the field of urogynecologic surgery has been subject to deep changes. A thorough understanding of the injury mechanisms responsible for pelvic organ prolapse (POP) and urinary incontinence in women, greatly contributed to the development of innovative surgical techniques and changing therapeutic approaches. The variety of treatment options to correct POP and incontinence has greatly expanded, partly thanks to the development of several advanced surgical kits by biotechnology companies.

Surgical management of pelvic organ prolapse in women.

Background: Pelvic organ prolapse may occur in up to 50% of parous women. A variety of urinary, bowel and sexual symptoms may be associated with the prolapse.

Objectives: To determine the effects of the many different surgeries used in the management of pelvic organ prolapse.

Surgical management of pelvic organ prolapse in women: the updated summary version Cochrane review.

Introduction And Hypothesis: A previous version of the Cochrane review for prolapse surgery in 2008 provided two conclusions: abdominal sacrocolpopexy had lower recurrent vault prolapse rates than sacrospinous colpopexy but this was balanced against a longer time to return to activities of daily life. An additional continence procedure at the time of prolapse surgery might be beneficial in reducing post-operative stress urinary incontinence; however, this was weighed against potential adverse effects. The aim of this review is to provide an updated summary version of the current Cochrane review on the surgical management of pelvic organ prolapse.

Laparoscopic removal of intravesical mesh following pelvic organ prolapse mesh surgery.

With the increasing popularity of mesh in prolapse surgery, complications such as intravesical mesh will arise more frequently. In three cases intravesical mesh was identified in the trigone of the bladder following laparoscopic mesh hysteropexy, open sacral colpopexy, and transvaginal mesh repair and presented 9 months to 7 years later with a variety of symptoms including recurrent urinary tract infections, suprapubic pain, and constant urinary leakage. Each underwent uncomplicated laparoscopic transvesical removal of intravesical mesh.
