Schizophrenia is associated with abnormal levels of blood inflammatory markers, which may be correlated with levels of psychopathology. Few previous studies have explored whether baseline inflammatory marker levels predict longitudinal changes in psychopathology. In the present study, we explored this association in a cohort of patients with schizophrenia.

We investigated inflammatory markers and psychopathology after 3, 6, and 12months of antipsychotic treatment for subjects with baseline and follow-up data from the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) schizophrenia trial. Linear regression models, controlling for multiple potential confounding factors, were used to investigate these associations.

There was a significant decrease in monocyte, ICAM, and adiponectin levels between baseline and 12months. Higher baseline blood interleukin-6 (IL-6) predicted greater reduction in PANSS total and general subscale scores at 3 and 6months, and PANSS negative subscale scores at 3mo more personalized medicine approaches for patients with schizophrenia.
The aim of this study was to analyze the radiological changes and determine the clinical and functional outcomes of proximal row carpectomy (PRC) over the long term.

Radiological changes after PRC occur in every patient while the clinical and functional outcomes remain stable over time.

This was a retrospective single-center study of patients who underwent PRC between January 2004 and December 2014. A clinical assessment (range of motion, grip strength), functional assessment (Mayo Wrist score and QuickDASH) and radiographic assessment (radiocapitate osteoarthritis, radiocapitate congruency) was done in every patient at the longest follow-up.

Thirty-one patients were reviewed with a mean follow-up of 97.9 months. The indications for PRC were SLAC (n=10), SNAC (n=5), Kienböck disease (n=9) and other conditions (n=7). The radiocapitate index, which is the radius of curvature of the tip of the capitate divided by the mean radius of curvature of the lunate fossa, went from 0.68 immediately postoperative to 0.74 at the final assessment (p=0.035). The mean flexion/extension arc was 93°. The mean grip strength was 25kg. The mean QuickDASH was 29 and the mean Mayo Wrist score was 69. Fifteen patients had radiocapitate osteoarthritis. Inhibitor Library Seven patients (22%) required revision surgery for wrist fusion after a mean of 18.6 months.

Radiological adaptation in the radiocapitate joint after PRC was found in this study. PRC is a reliable solution and yields stable outcomes over time for treating radiocarpal osteoarthritis, except in young adults and manual laborers who had a notable early revision rate.

Given their low citation rate, case reports may reduce a journal's impact factor (IF), making a journal less likely to accept them for publication. However, this concept has never been proven in a bibliometric study. This led us to carry out a bibliometric analysis to evaluate (1) the exact number of case reports published in orthopedics over a 2-year period, (2) their citation rate, (3) what the journals' IF would be if they had not published these case reports.

Publishing case reports reduces a journal's IF, bringing into question whether they should be published.

This was a retrospective bibliometric study. We focused on all the articles influencing the year 2017. We looked at all the journals in the "Orthopedics" discipline that had published at least one article in the years n-2 (=2015) or n-1 (=2016).

There were 1925 case reports among the 28,903 articles published in all orthopedics journals in 2015-2016, a 6.7% share of publications. Individually, each case report in 2015-2016 was cited an aves should be published. Indeed, the publication of case reports lowers the IF of scientific journals. However, we should not completely stop publishing case reports since they can be useful to clinicians caring for patients with rare diseases or medical conditions.

Cholelithiasis referrals often present with concomitant or isolated atypical symptoms such as reflux, bloating, or epigastric pain. We sought to identify the impact of preoperative symptomatology of atypical or dyspepsia-type biliary colic on operative and non-operative clinical outcomes.

A retrospective review of patients referred for gallstone disease from 2014 to 2018at a single institution in Los Angeles County was performed.

Of 746 patients evaluated for gallstone disease, 87.4% (n=652) underwent cholecystectomy - 90.8% (n=592) had symptom resolution postoperatively whereas 9.2% (n=60) did not. Over half presented with concomitant atypical and/or dyspepsia symptoms (n=411). Heartburn/reflux was significantly associated with unresolved symptoms postoperatively (OR 2.1,1.0-4.4, p=0.04). Overall, 11.1% (n=83) of all 746 patients and 20.2% of patients with atypical and/or dyspepsia symptoms improved with medical management of gastritis or Helicobacter pylori triple therapy pre/post-operatively.

Atypical biliary colic and/or dyspepsia is associated with unresolved symptoms following cholecystectomy. Such patients may benefit from H.pylori testing or PPI trial prior to cholecystectomy.

Guidance on post-cardiac arrest prognostication is largely based on data from out-of-hospital cardiac arrest (OHCA), despite clear differences between the OHCA and in-hospital cardiac arrest (IHCA) populations. Early prediction of mortality after IHCA would be useful to help make decisions about post-arrest care. We evaluated the ability of lactate and need for vasopressors after IHCA to predict hospital mortality.

Single center retrospective observational study of adult IHCA patients who achieved sustained return of spontaneous circulation (ROSC), required mechanical ventilation peri-arrest and had a lactate checked within 2 h after ROSC. We evaluated the association of post-ROSC lactate and need for vasopressors with mortality using multivariate logistic regression.

A total of 364 patients were included. Patients who received vasopressors within 3 h after ROSC had significantly higher mortality compared to patients who did not receive vasopressors (58% vs. 43%, p = 0.03). Elevated lactate level was associated with mortality (44% if lactate <5 mmol/L, 58% if lactate 5-10 mmol/L, and 73% if lactate >10 mmol/L, p < 0.
