BACKGROUND: One important cardiovascular morbidity that is associated with obesity hypoventilation syndrome (OHS) is the development of pulmonary hypertension (PH). However, few studies have assessed PH in OHS patients. Therefore, we prospectively assessed the prevalence of PH in a large sample of OHS patients. METHODS: In this prospective observational study, all consecutive OHS patients referred to the sleep disorders clinic during the study period were included...

In this issue of DOM, Zaccardi et al. present an analysis of hypoglycaemia-related hospitalizations in the Hospital Episodes Statistics (HES) administrative database of the English National Health Service. [1] Notable strengths of the work include a large sample size involving more than 100 000 cases of hypoglycaemia, and nationwide capture spanning a duration of ten years. Key conclusions include the possibility of a U-shaped relationship between risk of hypoglycaemia and age, as well as possible associations between social deprivation and ethnicity with greater risk of hypoglycaemia...

Wet tropical forests are among the most diverse ecosystems on Earth and can host several hundreds of tree species per hectare. To maintain such diversity, the community must contain large numbers of relatively rare species rather than be dominated by a few very common trees, as is often the case in temperate forests. Explaining the mechanisms preventing dominance by common species has been a major task of tropical forest ecology. One of the most promising mechanisms is negative density dependence (NDD) of tree abundance driven by pests, including fungal diseases ('pest pressure')...

Firefighters commonly encounter traumatic events during duty hours. The purpose of this study was to investigate the characteristics of duty-related trauma as risk factors for posttraumatic stress disorder in professional firefighters. A sample of 212 firefighters participated in the study and completed self-reported questionnaires. Potentially traumatic events (PTE) were assessed using a list of 17 traumatic event types. The posttraumatic stress symptoms (PTSS) were measured by the Impact of Event Scale-Revised (Lim et al...

We thank Ricceri et al. for their comments (1) and interest in our study (2). Despite the recent advances in prevention and treatment of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, these two chronic infections still represent the most common cause of chronic liver disease. Dermatologists are frequently encountering patients with psoriatic disease who have concomitant HBV or HCV infection in daily clinical practice. Dr Ricceri provided in his letter further long-term follow-up data (60 months) on the use of etanercept or adalimumab in 17 psoriatic patients affected by past HBV infection or chronic HCV infection...

Mutations in MAN1, a protein of the nuclear envelope, cause bone phenotypes characterized by hyperostosis. The mechanism of this pro-osteogenic phenotype remains unknown. We increased and decreased MAN1 expression in mesenchymal stem cells (MSC) upon which standard osteogenic and adipogenic differentiation were performed. MAN1 knockdown increased osteogenesis and mineralization. In contrast, osteogenesis remained stable upon MAN1 overexpression. Regarding a mechanism, we found that low levels of MAN1 facilitated the nuclear accumulation of regulatory smads and smads-related complexes, with a concurrently high expression of nuclear β-Catenin...

We have read with interest the article by Piaserico et al. concerning the use of tumour necrosis factor-alpha (TNF-alpha) blocking agent adalimumab in psoriatic patients with concomitant hepatitis B virus (HBV) or hepatitis C virus (HCV). The authors describe 17 psoriatic patients affected by chronic HBV infection and 20 affected by chronic HCV who were successfully treated with adalimumab with no evidence of HBV or HCV reactivation in a mean follow-up period of 27 and 40 months, respectively. We have previously described our successful experience of treatment with anti-TNF-alpha therapy in 17 psoriatic patients (11 with past HBV infection, 5 with chronic HCV infection and one affected by both HBV and HCV) without the use of lamivudine or adenofovir, and can now report on long-term follow-up data (mean follow-up period of 60 months)...

Purpose To evaluate the diagnostic significance of preoperatively and intraoperatively performed contrast-enhanced ultrasound (CEUS/IOCEUS) in the diagnosis of liver tumors in comparison to magnetic resonance imaging (MRI) and histopathology. Materials and Methods Retrospective analysis of 70/317 patients who underwent surgery for liver tumors between January 2012 and October 2015. Findings of CEUS and IOCEUS were compared to MRI. CEUS and IOCEUS were performed using multifrequency linear probes (1 - 5, 6 - 15 MHz) after bolus injection of 1 - 5 ml sulfur hexafluoride microbubbles...

Background Magnetic resonance imaging (MRI) has become an essential imaging modality for the evaluation of head & neck pathologies. However, the diagnostic power of MRI is strongly related to the appropriate selection and interpretation of imaging protocols and sequences. The aim of this article is to review state-of-the-art sequences for the clinical routine in head & neck MRI and to describe the evidence for which medical question these sequences and techniques are useful. Method Literature review of state-of-the-art sequences in head & neck MRI...

Previously we reported the production and characterization of monoclonal antibody 1H6 raised against (T4G4)2 intermolecular guanine quadruplex (G4) DNA structures (Henderson A. et al. (2014) Nucleic Acids Res., 42, 860-869; Hoffmann R.F. et al. (2016) Nucleic Acids Res., 44, 152-163). It was shown that 1H6 strongly stains nuclei and has exquisite specificity for heterochromatin by immuno-electron microscopy. Here we extend our studies of 1H6 reactivity using enzyme-linked immunosorbent assay (ELISA) and microscale thermophoresis (MST)...

BACKGROUND: Pathological extramural vascular invasion (EMVI) is an independent prognostic factor in rectal cancer, but can also be identified on MRI-detected extramural vascular invasion (mrEMVI). We perform a meta-analysis to determine the risk of metastatic disease at presentation and after surgery in mrEMVI-positive patients compared with negative tumours. METHODS: Electronic databases were searched from January 1980 to March 2016. Conventional meta-analytical techniques were used to provide a summative outcome...

In this study, single particle mass spectra signatures of both coal burning boiler and biomass burning boiler emitted particles were studied. Particle samples were suspended in clean Resuspension Chamber, and analyzed by ELPI and SPAMS simultaneously. The size distribution of BBB (biomass burning boiler sample) and CBB (coal burning boiler sample) are different, as BBB peaks at smaller size, and CBB peaks at larger size. Mass spectra signatures of two samples were studied by analyzing the average mass spectrum of each particle cluster extracted by ART-2a in different size ranges...

Thibaud Mathis, Laurent Kodjikian
In response to the article by Parodi et al. about choroidal neovascularization (CNV) associated with Multiple Evanescent White Dot Syndrome (MEWDS) treated with intravitreal Ranibizumab. This article highlights the efficacy of intravitreal Ranibizumab in the treatment of CNV associated with MEWDS. In our experience, CNV is mostly associated with MEWDS in cases of a wider inflammatory spectrum such as overlapping syndrome with multifocal choroiditis (MFC) or punctuate inner choroidopathy (PIC). The whole pattern of the case presented in the article is compatible with the diagnosis of PIC, meaning that this case described an overlapping between MEWDS and PIC diagnoses...
