OBJECTIVES: Whereas left-sided congenital diaphragmatic hernias (L-CDH) have been extensively studied and their prognostic parameters delineated, right-sided hernias (R-CDH) have not. Published results remain inconclusive. The aim of this study is to evaluate if proven prognostic indicators of postnatal survival in the fetus with L-CDH apply to the fetus with R-CDH. METHODS: Retrospective single-center study of R-CDH fetuses with available prenatal studies assessed for fetal lung volume by means of ultrasound-measured observed versus expected (O/E) lung area to head circumference (LHR) and magnetic resonance-calculated O/E total lung volume (TLV) in a 12-year time period...

OBJECTIVE: The Joint Commission recommends all patients be screened for suicide. However, differences in suicide attempt and death rates may affect how well tools predict risk across age groups. Our objective was to determine whether item 9 of the Patient Health Questionnaire (PHQ9) predicts risk for suicide attempts and deaths across age groups. METHODS: PHQ9s completed by adult outpatients treated for mental health conditions in 2010-2012 at four Mental Health Research Network-affiliated healthcare systems were used to measure depression severity and suicidal ideation...

SCOPE: Sofrito, a key component of the Mediterranean diet, provides nutritional interest due to its high content in bioactive compounds from tomato and olive oil, and especially to the lipid matrix in which these compounds are found. In this study, the potential beneficial effects of dietary intake of sofrito on obesity-related vascular alterations were explored in obese Zucker rats. METHODS AND RESULTS: Obese and lean rats were fed a control diet supplemented or not with 2% (w/w) sofrito for 8 weeks...

Plasma products, including fresh frozen plasma, are administered extensively in a variety of settings from massive transfusion to vitamin K antagonist reversal. Despite the widespread use of plasma as a hemostatic agent in bleeding patients, its effect in comparison with other available choices of hemostatic therapies is unclear. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PubMed Central, and databases of ongoing trials for randomized controlled trials that assessed the efficacy and/or safety of therapeutic plasma as an intervention to treat bleeding patients compared with other interventions or placebo...

BACKGROUND: In this study, markers of coagulation and fibrinolysis were assessed during early and delayed microsurgical reconstruction in patients with traumatic defects of their lower legs to analyse whether an imbalance of the hemostasis after trauma might predispose the development of vascular complications. METHODS: The prospective study included 70 patients. In 35 patients, surgery was performed within 72 hours after injury. In 35 other patients, delayed free flap transfer was performed between 14-21 days after trauma...

SCOPE: Oleanolic acid (OA) is an important triterpenic compound found in olive oil, however little is known about its concentrations in human plasma. We aimed to determine plasma OA levels in a healthy Spanish population and compare them with estimates of dietary olive oil intake. METHODS AND RESULTS: The final study sample included 141 individuals randomly selected from the European Prospective Investigation into Cancer and Nutrition Spanish cohort. Dietary olive oil intake was estimated using validated dietary history questionnaires...

INTRODUCTION: Modifications of the temporomandibular joint position after mandible osteotomy are reluctantly accepted in orthognathic surgery. To tackle this problem, we developed a new navigation system using miniaturized electromagnetic sensors. Our imageless navigation approach is therefore optimized to avoid complications of previously proposed optical approaches such as the interference with established surgical procedures and the line of sight problem. MATERIAL AND METHODS: High oblique sagittal split osteotomies were performed on 6 plastic skull mandibles in a laboratory under conditions comparable to the operating theatre...

Accurate methods for cross-sectional incidence estimation are needed for HIV prevention research. The Limiting Antigen Avidity (LAg-Avidity) assay has been marketed by two vendors, Maxim Biomedical and Sedia BioSciences Corporation. Performance differences between the two versions of the assay are unknown. We tested a total 1,410 treatment-naive samples with both versions of the assay. The samples came from 176 seroconverters from the Zimbabwe Hormonal Contraception and HIV Study. The correlation between the two versions of the assay was 0...

Herein, the synthesis of a novel family of squaraines (SQ) and their application in p-type dye-sensitized solar cells (DSSC) is presented. In particular, two sets of SQs were designed. The SQs have been characterized by using a joint theoretical, photophysical and electrochemical approach. Importantly, the presence of different central groups forces them into a frozen cis (dicyanovinyl group) or a trans (oxygen group) conformation. Based on the latter, the current work enables the direct comparison between cis and trans isomers, as well as the impact of a different number of anchors...

REVIEW
Oliver Krenkel, Frank Tacke
Macrophages represent a key cellular component of the liver, and are essential for maintaining tissue homeostasis and ensuring rapid responses to hepatic injury. Our understanding of liver macrophages has been revolutionized by the delineation of heterogeneous subsets of these cells. Kupffer cells are a self-sustaining, liver-resident population of macrophages and can be distinguished from the monocyte-derived macrophages that rapidly accumulate in the injured liver. Specific environmental signals further determine the polarization and function of hepatic macrophages...

This study evaluated the effect of the solid state cultivation (SSC) time of rice bran by Rhizopus oryzae on γ-oryzanol recovery and its antioxidant properties. Gamma-oryzanol was extracted with organic solvents and its extracts were characterized by GC-FID and HPLC-UV. The antioxidant capacity was assessed by DPPH and ABTS(+) assays, β-carotene/linoleic acid system, and reduction of oxidation in lipid system. The biomass showed the γ-oryzanol recovery increased by 51.5% (20.52mg/g), and 5.7% in polyunsaturated fatty acids...

Proton Nuclear Magnetic Resonance ((1)H NMR) was employed to study monovarietal commercial Spanish extra-virgin olive oils (EVOO) (Arbequina, Arroniz, Cornicabra, Hojiblanca and Picual). Each sample was analyzed by a standard pulse and by an experiment suppressing the main lipid signals, enabling the detection of signals of minor components. The aim was to determine the possibilities of both (1)H NMR approaches to characterize EVOO composition, focusing on acyl groups, squalene, sterols, triterpene acids/esters, fatty alcohols, wax esters and phenols (lignans, tyrosol, hydroxytyrosol, oleocanthal, oleacein, oleokoronal, oleomissional, ligstrodials and oleuropeindials), and to determine hydrolysis and oxidation levels...

Although many people recognize Oliver Cromwell by name, few know more than the barest details of his life or his legacy, and fewer still of the "ague" that ended his brief reign as Lord Protector of the Commonwealth of England, Scotland and Ireland and one of Britain׳s greatest generals. He died suddenly at age 59. Cromwell was the "terror of Europe" during that period. His physicians diagnosed his fatal disorder as "bastard tertian ague." A contemporary analysis of his clinical record, including one with the aid of the U...

Recent epidemiological evidence demonstrated that diabetes is a risk factor for AD onset and development. Indeed, meta-analyses of longitudinal epidemiologic studies show that diabetes increases AD risk by 50-100%, being insulin resistance (IR) the main binding link between diabetes and AD. Astrocytes are the foremost cerebral macroglial cells and are responsible for converting glucose into lactate and transfer it to neurons that use it as fuel, but Aβ(1-42) impairs insulin signaling and glycogen storage. Recent prospective studies showed that the Mediterranean diet is associated with lower incidence of AD...

Group 6 d6 metal complexes with arylisocyanide ligands are earth-abundant alternatives to photoactive complexes made from precious metals such as Ru(II), Re(I), Os(II), or Ir(III). Some of them have long-lived 3MLCT excited states that exhibit luminescence with good quantum yields combined with nano- to microsecond lifetimes, and they are very strongly reducing. Recent studies have demonstrated that Cr(0), Mo(0), and W(0) arylisocyanides have great potential for application in luminescent devices, photoredox catalysis, and dye-sensitized solar cells...

The rapid and direct determination of enantiomeric ratios is of increasing interest due to the significantly reduced effort compared to chromatographic methods and the large number of analytes, for instance in enantioselective catalysis. Current strategies include colorimetric assays, (a)chiral solvating reagents for NMR spectroscopy and metal complexes for CD sensing. We report the determination of enantiomeric ratios based on the self-induced diastereomeric anisochronism (SIDA) effect. Alanine derivatives that represent chiral products of enantioselective catalysis, such as the well-established hydrogenation of dehydroamino acids, were investigated...

We report on a series of eight diaryl-6-oxo-verdazyl radicals containing a tert-butyl group at the C(3) position regarding their crystal structure and magnetic properties by means of magnetic susceptibility measurements in combination with quantum chemical calculations using the first-principles bottom-up approach. The latter method allows for a qualitative prediction and detailed analysis of the correlation between solid state architecture and magnetic properties. Although the perturbation in the molecular structure by varying the substituent of the N-aryl-ring may appear small, the effects upon the structural parameters controlling intermolecular magnetic coupling interactions are strong, resulting in a wide spectrum of cooperative magnetic behavior...

Determining the structure of a protein by any method requires various contributions from experimental and computational sides. In a recent study, high-density cross-linking/mass spectrometry (HD-CLMS) data in combination with ab initio structure prediction determined the structure of human serum albumin (HSA) domains, with an RMSD to X-ray structure of up to 2.5 Å, or 3.4 Å in the context of blood serum. This paper reports the blind test on the readiness of this technology through the help of Critical Assessment of protein Structure Prediction (CASP)...

We conducted a retrospective observational study at four German university hospitals of patients with laboratory-confirmed influenza in 2014/2015. Overall, a fatality rate of 8% was observed. Significantly more A(H1N1)pdm09 patients were admitted to ICU compared to those with A(H3N2). However, fatal outcome was not significantly increased among A(H1N1)pdm09 cases. Nosocomial infections were seen in 17% of cases. Systematic collection of data from hospitals will complement national influenza surveillance.

Multiple drug hypersensitivity (MDH) is a syndrome that develops as a consequence of massive T-cell stimulations and is characterized by long-lasting drug hypersensitivity reactions (DHR) to different drugs. The initial symptoms are mostly severe exanthems or drug rash with eosinophilia and systemic symptoms (DRESS). Subsequent symptoms due to another drug often appear in the following weeks, overlapping with the first DHR, or months to years later after resolution of the initial presentation. The second DHR includes exanthema, erythroderma, DRESS, Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), hepatitis, and agranulocytosis...
