Assessing the impact of sex on high-frequency repetitive transcranial magnetic stimulation´s clinical response in schizophrenia - results from a secondary analysis.

Background: The evidence for repetitive transcranial magnetic stimulation (rTMS) to treat negative symptoms in schizophrenia (SCZ) is increasing, although variable response rates remain a challenge. Subject´s sex critically influences rTMS´ treatment outcomes. Females with major depressive disorder are more likely to respond to rTMS, while SCZ data is scarce.

Effects of high-frequency prefrontal rTMS on heart frequency rates and blood pressure in schizophrenia.

Background: Repetitive transcranial magnetic stimulation (rTMS) is a safe non-invasive neuromodulation technique used for the treatment of various neuropsychiatric disorders. The effect of rTMS applied to the cortex on autonomic functions has not been studied in detail in patient cohorts, yet patients who receive rTMS may have disease-associated impairments in the autonomic system and may receive medication that may pronounce autonomic dysfunctions.

Methods: Using data from the 'rTMS for the Treatment of Negative Symptoms in Schizophrenia' (RESIS) trial we evaluated the effect of rTMS applied to the left dorsolateral prefrontal cortex (DLPFC) on autonomic nervous system-related parameters such as blood pressure (BP) and heart rate (HR) in both reclining and standing postures from screening up to 105 days after intervention among patients with schizophrenia.

Challenges and opportunities for Multi-National Investigator-Initiated clinical trials for ALS: European and United States collaborations.

An inherent challenge to clinical trials that aim to test the efficacy of experimental therapeutics for patients with amyotrophic lateral sclerosis (ALS) is the relative rarity of the disease. A promising solution to this problem is a multi-center approach that ideally includes sites distributed across a broad geographic area. In support of such an approach, the European E-RARE program and the United States National Institutes of Health (NIH) partnered to support the investigator-initiated ROCK-ALS trial (Eudra-CT-Nr.

Mortality in COVID-19 patients with acute respiratory distress syndrome and corticosteroids use: a systematic review and meta-analysis.

Objectives: The acute respiratory distress syndrome (ARDS) secondary to viral pneumonitis is one of the main causes of high mortality in patients with COVID-19 (novel coronavirus disease 2019). We systematically reviewed mortality in COVID-19 patients with ARDS and the potential role of systemic corticosteroids in COVID-19 patients.

Methods: Electronic databases and country-specific healthcare databases were searched to identify relevant studies/reports.

Efficacy of high-frequency repetitive transcranial magnetic stimulation in schizophrenia patients with treatment-resistant negative symptoms treated with clozapine.

Background: Repetitive transcranial magnetic stimulation (rTMS) is a promising augmentation treatment for schizophrenia, however there are few controlled studies of rTMS augmentation of clozapine.

Methods: Using data from the 'rTMS for the Treatment of Negative Symptoms in Schizophrenia' (RESIS) trial we examined the impact of rTMS on PANSS total, general, positive and negative symptoms among participants on clozapine. rTMS was applied to the left dorsolateral prefrontal cortex (DLPFC) for five treatment sessions/week for 3-weeks as augmentation for patients with a predominant negative syndrome of schizophrenia, as rated on PANSS.

Nasopharyngeal airway aspiration: An uncommon cause of sudden respiratory distress in hospitalized patients.

An elderly, bed ridden patient with a history of stroke was admitted for management of aspiration pneumonia. Two days after insertion of a nasopharyngeal airway, sudden respiratory distress prompted further investigations which led to the eventual diagnosis and removal of the nasopharyngeal airway that had been aspirated. The device was removed under conscious sedation with fiber optic bronchoscopy.

Efficacy of high-frequency repetitive transcranial magnetic stimulation on PANSS factors in schizophrenia with predominant negative symptoms - Results from an exploratory re-analysis.

Repetitive transcranial magnetic stimulation (rTMS) applied to the left frontal lobe is discussed to be a promising add-on treatment for negative symptoms in schizophrenia. The Positive and Negative Syndrome Scale (PANSS) has been used as outcome parameter in several previous rTMS trials, but studies focusing on PANSS factor analyses are lacking. For this purpose, we used the available PANSS data of the 'rTMS for the Treatment of Negative Symptoms in Schizophrenia' (RESIS) trial to calculate different literature-based PANSS factors and to re-evaluate the impact of rTMS on negative symptoms in this trial.

Predicting Response to Repetitive Transcranial Magnetic Stimulation in Patients With Schizophrenia Using Structural Magnetic Resonance Imaging: A Multisite Machine Learning Analysis.

Background: The variability of responses to plasticity-inducing repetitive transcranial magnetic stimulation (rTMS) challenges its successful application in psychiatric care. No objective means currently exists to individually predict the patients' response to rTMS.

Methods: We used machine learning to develop and validate such tools using the pre-treatment structural Magnetic Resonance Images (sMRI) of 92 patients with schizophrenia enrolled in the multisite RESIS trial (http://clinicaltrials.

Cognitive Effects of High-Frequency rTMS in Schizophrenia Patients With Predominant Negative Symptoms: Results From a Multicenter Randomized Sham-Controlled Trial.

Cognitive impairments are one of the main contributors to disability and poor long-term outcome in schizophrenia. Proof-of-concept trials indicate that repetitive transcranial magnetic stimulation (rTMS) applied to the left dorsolateral prefrontal cortex (DLPFC) has the potential to improve cognitive functioning. We analyzed the effects of 10-Hz rTMS to the left DLPFC on cognitive deficits in schizophrenia in a large-scale and multicenter, sham-controlled study.

Real life management of community-acquired Pneumonia in adults in the Gulf region and comparison with practice guidelines: a prospective study.

Background: Very few data exist on the management of community-acquired pneumonia (CAP) in patients admitted to hospitals in the Gulf region. The objectives of this study were to describe treatment patterns for CAP in 38 hospitals in five Gulf countries (United Arab Emirates, Kuwait, Bahrain, Oman, and Qatar) and to compare the findings to the most recent Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) guidelines.

Methods: This was a prospective, observational study conducted between January 2009 and February 2011.

Left prefrontal high-frequency repetitive transcranial magnetic stimulation for the treatment of schizophrenia with predominant negative symptoms: a sham-controlled, randomized multicenter trial.

Background: Investigators are urgently searching for options to treat negative symptoms in schizophrenia because these symptoms are disabling and do not respond adequately to antipsychotic or psychosocial treatment. Meta-analyses based on small proof-of-principle trials suggest efficacy of repetitive transcranial magnetic stimulation (rTMS) for the treatment of negative symptoms and call for adequately powered multicenter trials. This study evaluated the efficacy of 10-Hz rTMS applied to the left dorsolateral prefrontal cortex for the treatment of predominant negative symptoms in schizophrenia.

Unreported neurological complications of Gemella bergeriae infective endocarditis.

We report the first case of native aortic and mitral valve endocarditis due to Gemella bergeriae from the Middle East in a young patient with rheumatic heart disease. Our case illustrates a fulminant course of infection with G. bergeriae endocarditis that was complicated by embolic stroke, as well as intracerebral and subarachnoid haemorrhage secondary to rupture of a mycotic aneurysm in the right middle cerebral artery.

Acute peripheral polyneuropathy with multiorgan failure: a diagnostic dilemma.

We describe the case of a young man who presented with abdominal pain, vomiting and acute symmetric peripheral polyneuropathy. He was noted to have high anion gap metabolic acidosis with high lactate levels and persistently high arterial and venous pO2 values. The cerebrospinal fluid was acellular with a high protein and the nerve conduction study was consistent with axonal sensorimotor neuropathy.

Challenges for academic investigator-initiated pediatric trials for rare diseases.

Background: Clinical trials require great effort, time, expertise, and money. For clinicians at university hospitals with their full work load of teaching and medical care, the planning of an investigator-initiated clinical trial seems almost unthinkable. Despite their expertise in distinct diseases, university clinicians lack the time necessary to organize the funding and to initiate and conduct Phase III clinical trials in adults or in children.

Mycophenolic acid mediated disruption of the intestinal epithelial tight junctions.

Gastrointestinal toxicity is a common adverse effect of mycophenolic acid (MPA) treatment in organ transplant patients, through poorly understood mechanisms. Phosphorylation of myosin light chain 2 (MLC2) is associated with epithelial tight junction (TJ) modulation which leads to defective epithelial barrier function, and has been implicated in GI diseases. The aim of this study was to investigate whether MPA could induce epithelial barrier permeability via MLC2 regulation.

Safety and Efficacy of the ACE-Inhibitor Ramipril in Alport Syndrome: The Double-Blind, Randomized, Placebo-Controlled, Multicenter Phase III EARLY PRO-TECT Alport Trial in Pediatric Patients.

Introduction. Retrospective observational data show that ACE-inhibitor therapy delays renal failure and improves life expectancy in Alport patients with proteinuria. The EARLY PRO-TECT Alport trial assesses the safety and efficacy of early therapy onset with ramipril in pediatric Alport patients.

Cold plasma is well-tolerated and does not disturb skin barrier or reduce skin moisture.

Background: Cold plasma, a new treatment principle in dermatology based on ionic discharge delivering reactive molecular species and UV-light, exhibits strong antimicrobial efficacy in vitro and in vivo. Before implementing plasma as new medical treatment tool, its safety must be proven, as well as assessing skin tolerance and patient acceptance.

Patients And Methods: We investigated the plasma effects of three different plasma sources (pulsed, non-pulsed atmospheric pressure plasma jet (APPJ) and a dielectric barrier discharge (DBD)) on the transepidermal water loss (TEWL) and skin moisture after treating the fingertips of four healthy male volunteers.

Prophylactic use of laxative for constipation in critically ill patients.

Background: This study was designed to evaluate the use of laxative prophylaxis for constipation in intensive care unit (ICU) and the impact of early versus late bowel movement on patient's outcome.

Methods: The study was a prospective, randomized controlled trial in critically ill ventilated adult patients, who were expected to stay on ventilator for >72 h. Control group did not receive any intervention for bowel movement for the first 72 h, whereas interventional group received prophylactic dose of lactulose 20 cc enterally every 12 h for the first 72 h.

Thoracic epidural anesthesia attenuates endotoxin-induced impairment of gastrointestinal organ perfusion.

Background: Systemic inflammation can be associated with a redistribution of organ blood flow and a decrease in gastrointestinal perfusion. Regional sympathetic blockade by means of thoracic epidural anesthesia (TEA) has been shown to improve intestinal microcirculation during systemic inflammation. This study tests the hypothesis that during systemic inflammation, TEA attenuates the impairment of gastrointestinal organ perfusion without compromising blood flow to vital organs.

Percutaneous tracheostomy in critically ill patients: 24 months experience at a tertiary care hospital in United Arab Emirates.

Objective: We assessed the safety and complications related to percutaneous tracheostomy (PCT) without bronchoscopic guidance in our intensive care unit (ICU).

Methods: The prospective data over a period of 24 months were collected for patients who underwent PCT. Major, minor and long-term complications were recorded.

Volume therapy with colloid solutions preserves intestinal microvascular perfusion in endotoxaemia.

Colloid solutions have been suggested to improve microvascular perfusion due to their anti-inflammatory properties. Whether this also applies for the gut, an important immunological organ vulnerable to hypoperfusion is unknown. This study investigated intestinal microcirculation of endotoxaemic rats after volume therapy with colloid solutions such as hydroxyethyl starch (HES) and gelatin or isotonic saline (NaCl).
