Treatment-associated mRNA co-expression changes in monocytes of patients with posttraumatic stress disorder.

PTSD is a prevalent mental disorder that results from exposure to extreme and stressful life events and comes at high costs for both the individual and society. Therapeutic treatment presents the best way to deal with PTSD-the mechanisms underlying change after treatment, however, remain poorly understood. While stress and immune associated gene expression changes have been associated with PTSD development, studies investigating treatment effects at the molecular level so far tended to focus on DNA methylation.

The influence of the behavioural inhibition system on the development of PTSD-like symptoms after presentation of a traumatic film in healthy subjects.

Background: The Behavioural Inhibition System (BIS) as a neural system controlling motivation and behaviour, has previously been linked to multiple mental disorders, including Post-traumatic Stress Disorder (PTSD). BIS-sensitivity could increase the likelihood of PTSD development after trauma. However, previous studies have largely measured BIS-sensitivity retrospectively (i.

Mitochondrial DNA as a marker for treatment-response in post-traumatic stress disorder.

Post-traumatic stress disorder (PTSD) is a serious mental health condition thought to be mediated by a dysregulated stress response system. Stress, especially chronic stress, affects mitochondrial activity and their efficiency in duplicating their genomes. Human cells contain numerous mitochondria that harbor multiple copies of their own genome, which consist of a mixture of wild type and variant mtDNA - a condition known as mitochondrial heteroplasmy.

Increased accuracy of FNA-based cytological diagnosis of pancreatic lesions by use of an ethanol-based fixative system: A STROBE compliant study.

EUS-guided fine needle aspiration cytology (FNA) is the gold standard of evaluation of solid pancreatic lesions. However, accuracy is generally low. The aim of this study was to compare the diagnostic yield of conventional cytology (CC) with liquid-based cytological analysis using an ethanol based fixative system (LBC) without onsite cytopathological assessment.

Adenoma detection rate using narrow-band imaging is inferior to high-definition white light colonoscopy in screening and surveillance colonoscopies in daily clinical care: A randomized controlled trial.

Background: Despite recent advances in endoscopic technology adenoma miss rate still is up to 20% contributing to interval cancers. Improved imaging modalities have been introduced to increase adenoma detection rate (ADR). Recently, narrow-band imaging (NBI) (Exera II series, Olympus Corporation) was not significantly better than high-definition white light colonoscopy (HD-WLC).

Clinical predictors for a complicated course of disease in an inception cohort of patients with ulcerative colitis: results from the prospective, observational EPICOL study.

Purpose: The clinical course of ulcerative colitis (UC) is highly heterogeneous, with 20 to 30% of patients experiencing chronic disease activity requiring immunosuppressive or biologic therapies. The aim of this study was to identify predictors for a complicated disease course in an inception cohort of patients with UC.

Methods: EPICOL was a prospective, observational, inception cohort (UC diagnosis, ≤ 6 months) study in 311 patients with UC who were naive to immunosuppressants (IS)/biologics.

Hidden hazards of SARS-CoV-2 transmission in hospitals: A systematic review.

Despite their considerable prevalence, dynamics of hospital-associated COVID-19 are still not well understood. We assessed the nature and extent of air- and surface-borne SARS-CoV-2 contamination in hospitals to identify hazards of viral dispersal and enable more precise targeting of infection prevention and control. PubMed, ScienceDirect, Web of Science, Medrxiv, and Biorxiv were searched for relevant articles until June 1, 2021.

Altered fibrin clot structure and dysregulated fibrinolysis contribute to thrombosis risk in severe COVID-19.

The high incidence of thrombotic events suggests a possible role of the contact system pathway in COVID-19 pathology. In this study, we determined the altered levels of factor XII (FXII) and its activation products in critically ill patients with COVID-19 in comparison with patients with severe acute respiratory distress syndrome related to the influenza virus (acute respiratory distress syndrome [ARDS]-influenza). Compatible with those data, we found rapid consumption of FXII in COVID-19 but not in ARDS-influenza plasma.

Sex-specific differences in plasma levels of FXII, HK, and FXIIa-C1-esterase inhibitor complexes in community-acquired pneumonia.

Sex-dependent differences in immunity and coagulation play an active role in the outcome of community-acquired pneumonia (CAP). Contact phase proteins act at the crossroads between inflammation and coagulation thus representing a point of convergence in host defense against infection. Here, we measured the levels of factor XII (FXII), FXIIa-C1 esterase inhibitor (C1INH) complexes, and high-molecular-weight kininogen (HK) in plasma of patients with CAP and correlated them to clinical disease severity.

Ethanol-based fixation is superior to conventional brush cytology in the evaluation of indeterminate biliary strictures by endoscopic retrograde cholangiography.

The aim of this study was to compare the diagnostic yield of conventional cytology (CC) with ethanol-based fixation, a cytological analysis using an ethanol based fixative system including a cell block procedure (EBF) to evaluate indeterminate biliary strictures (IBStr). We also compared additionally taken fluorescence-guided forceps biopsies (FB) with EBF concerning a potential additive diagnostic benefit.Early detection and accurate diagnosis are crucial for patients with suspected carcinoma within the biliary tree to preserve curative treatment options but diagnostics and patient care in the evaluation of IBStr are still challenging.

Loss of LRP1 promotes acquisition of contractile-myofibroblast phenotype and release of active TGF-β1 from ECM stores.

In healing tissue, fibroblasts differentiate to α-smooth muscle actin (SMA)-expressing contractile-myofibroblasts, which pull the wound edges together ensuring proper tissue repair. Uncontrolled expansion of the myofibroblast population may, however, lead to excessive tissue scarring and finally to organ dysfunction. Here, we demonstrate that the loss of low-density lipoprotein receptor-related protein (LRP) 1 overactivates the JNK1/2-c-Jun-Fra-2 signaling pathway leading to the induction of α-SMA and periostin expression in human lung fibroblasts (hLF).

A study on the correlation of gastrointestinal bleeding and meteorological factors - is there a weather condition for GI bleeding?

Aim:  We tried to identify a possible correlation between meteorological factors and the frequency of gastrointestinal bleeding (GIB).

Methods:  We analyzed all endoscopic examinations performed because of suspected GIB from 2013 to 2016 at Jena University Hospital, Germany. Confirmed bleeding events were correlated with local meteorological data and meteorological season using multivariate analysis.

Pirfenidone inhibits motility of NSCLC cells by interfering with the urokinase system.

Pirfenidone (PFD) is an orally available synthetic drug which has been approved for the treatment of idiopathic pulmonary fibrosis. In addition to its anti-fibrotic properties, PFD also exerts anti-tumor effects in cancer models by inducing alterations in the tumor microenvironment. Here, we demonstrate that PFD reduces proliferation, 2D- and 3D-migration as well as colony formation of the non-small-cell lung carcinoma (NSCLC) cells.

Predictive parameters for the clinical course of Crohn's disease: development of a simple and reliable risk model.

Purpose: The aim of our study was to identify clinical parameters in recently diagnosed Crohn's disease (CD) patients for prediction of their disease course.

Methods: EPIC (Early Predictive parameters of Immunosuppressive therapy in Crohn's disease) is a prospective, observational study in 341 patients with a recent CD diagnosis (≤ 6 months), and naïve to immunosuppressants (IS) and anti-tumor necrosis factor α (TNF) agents. Patient characteristics were documented up to 2 years.

Neoadjuvant plus adjuvant or only adjuvant nab-paclitaxel plus gemcitabine for resectable pancreatic cancer - the NEONAX trial (AIO-PAK-0313), a prospective, randomized, controlled, phase II study of the AIO pancreatic cancer group.

Background: Even clearly resectable pancreatic cancer still has an unfavorable prognosis. Neoadjuvant or perioperative therapies might improve the prognosis of these patients. Thus, evaluation of perioperative chemotherapy in resectable pancreatic cancer in a prospective, randomized trial is warranted.

Biomarkers in idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a chronic, debilitating, fibrotic lung disease leading to respiratory failure and ultimately to death. Being the prototype of interstitial lung diseases, IPF is characterized by marked heterogeneity regarding its clinical course. Despite significant progress in the understanding of its pathogenesis, we still cannot reliably predict the course of the disease and the response to treatment of an individual patient.

Advances in clinical pharmacy education in Germany: a quasi-experimental single-blinded study to evaluate a patient-centred clinical pharmacy course in psychiatry.

Background: The pharmacy profession has shifted towards patient-centred care. To meet the new challenges it is necessary to provide students with clinical competencies. A quasi-experimental single-blinded teaching and learning study was carried out using a parallel-group design to evaluate systematically the benefits of clinical teaching in pharmacy education in Germany.

Magnetic resonance imaging following fat obliteration of the frontal sinus.

The paper describes the evaluation of magnetic resonance imaging (MRI) following osteoplastic flap procedure with fat obliteration. MRI scans performed in patients after surgery between 1st January 1986 and 31st December 1997 were evaluated. Outcome parameters were time-dependent changes in the distribution of adipose or connective tissue, development of necroses or oil cysts, recurrences, inflammatory complications, or mucocoeles.

Long-term study of endonasal duraplasty and review of the literature.

Many different techniques have been proposed to repair frontobasal dura mater lesions. Because of its low morbidity and high success rate, the endonasal approach has become a preferred route for treating cerebrospinal fluid fistulas of the anterior skull base. This article presents a retrospective evaluation of 136 endonasal duraplasties (126 patients) performed between July 1980 and May 1998 at a tertiary care facility.

Modern concepts of frontal sinus surgery.

Objectives/hypothesis: To validate the endonasal surgical approach to frontal sinus in inflammatory sinus disease, trauma, and selective tumor surgery, and to define the role of external approaches to the frontal sinus. Endonasal frontal sinusotomy can range from endoscopic removal of obstructing frontal recess cells or uncinate process to the more complex unilateral or bilateral removal of the frontal sinus floor as described in the Draf II-III drainage procedures. In contrast, the osteoplastic frontal sinusotomy remains the "gold standard" for external approaches to frontal sinus disease.

Experiences with endonasal surgery in angiofibroma.

Surgery is the most common treatment for angiofibromas, but the approach is still a major point of discussion. Five cases of angiofibroma with typical localisation were treated surgically by an endonasal approach at the Fulda Academic Teaching Hospital from 1994 to 1997. This article presents an analysis of the clinical findings, computer tomography and magnetic resonance imaging, preoperative embolization, operative technique and complications.

Videoendoscopic analysis of nasal steroid distribution.

Topical corticosteroids are one of the main pillars in the treatment of nasal polyps. The exact topography of their intranasal deposition has not yet been adequately visualised. The intranasal distribution of a 1% sodium fluorescein solution applied with original Pulmicort Topinasal (budesonide) metered pump bottles was analysed by videoendoscopy.

Unusual sinus of the styloid process.

The case of a 50-year-old man with an unusual sinus of the styloid process is presented. This anomaly caused recurrent otorrhea and repeated neck inflammation. The sinus was identified in the upper part of the styloid process and was resected completely as definitive treatment.

Extranasopharyngeal angiofibroma in a 15-month-old child.

Angiofibromas are usually characterized by typical location with involvement of the posterior nasal cavity and nasopharynx. They are most commonly found in adolescent males. Despite these facts, a case of an angiofibroma presented in a 15-month-old boy at an atypical site anterior and medial to the lacrimal sac.
