Primary peritoneal mesothelioma: A rare cause of malignant ascites

Abstract Introduction: The evaluation of peritoneal masses requires a focused, systematic approach. While peritoneal fluid analysis and axial imaging are essential to the workup, further analysis is often needed for a final diagnosis. We present a case of primary peritoneal mesothelioma mimicking peritoneal carcinomatosis of gastrointestinal origin on computerized tomography (CT) imaging. Case presentation: A 61-year-old man presented to the hospital with an approximate 1-month history of abdominal distention, dyspnea, nausea and fatigue. Peritoneal studies revealed serum-ascites-albumin-gradient (SAAG) of less than 1.1, consistent with non-portal hypertension ascites. CT abdomen revealed large-volume ascites with omental caking, concerning for peritoneal carcinomatosis. Peritoneal fluid cytology was initially inconclusive, prompting ultrasound-guided peritoneal biopsies, which revealed primary abdominal mesothelioma. Conclusions: Neither CT nor peritoneal cytology are typically sufficient for the diagnosis of peritoneal mesothelioma. When strong clinical suspicion exists, early tissue biopsies should be pursued

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Solution processable diketopyrrolopyrrole (DPP) cored small molecules with BODIPY end groups as novel donors for organic solar cells

PJS thanks the Royal Society for a Wolfson Research Merit Award.Two novel triads based on a diketopyrrolopyrrole (DPP) central core and two 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) units attached by thiophene rings have been synthesised having high molar extinction coefficients. These triads were characterised and used as donor materials in small molecule, solution processable organic solar cells. Both triads were blended with PC71BM as an acceptor in different ratios by wt% and their photovoltaic properties were studied. For both the triads a modest photovoltaic performance was observed, having an efficiency of 0.65%. Moreover, in order to understand the ground and excited state properties and vertical absorption profile of DPP and BODIPY units within the triads, theoretical DFT and TDDFT calculations were performed.Publisher PDFPeer reviewe

Homo Economicus, Behavioural Sciences, and Economic Regulation: On the Concept of Man in Internal Market Regulation and its Normative Basis

We investigate how EU law conceptualizes the individual to whom internal market regulation is addressed. Our analytical point of departure is a stylized information paradigm , whereby for reasons of internal market benefits, market players have to bear the burden of perceiving and processing information that is relevant in respect of an intended transaction, as well as disadvantages should they be ill-equipped to cope with this assignment. Although the ECJ implemented the normative concept of a well-informed, observant and circumspect consumer, it never adopted such a stylized information paradigm . The EU legislature assists market players in perceiving and processing information, and even seeks to steer their decision-making process. We reconsider whether or to what extent this should be understood as an advancement of an information paradigm or rather as a “behavioural turn”. Only a differentiated approach that balances the internal market rationale with potentially conflicting rights meets the exigencies of EU law
