Cam morphology of the proximal femur is an abnormal contour of the femoral head-neck junction present in approximately 15% to 25% of the asymptomatic population, predominantly in males. Alpha angle and femoral head-neck offset ratio are 2 objective measurement tools that define cam morphology. Both primary (idiopathic) and secondary cam deformity develops through distinct mechanisms. The cause of primary (idiopathic) cam morphology remains incompletely understood. Mounting evidence suggests that idiopathic cam morphology develops during adolescence through alterations in the capital femoral epiphysis in response to participation in vigorous sporting activity...

PURPOSE: Percutaneous radiofrequency ablation (RFA) of thyroid nodules is an alternative to surgical resection that offers the benefits of minimal scars for the patient, lower complication rates, and shorter treatment times. Ultrasound (US) is the preferred modality for guiding these procedures. The needle is usually kept within the US scanning plane to ensure needle visibility. However, this restricts flexibility in both transducer and needle movement and renders the procedure difficult, especially for inexperienced users...

A 35-year-old woman receiving immunosuppressionfor renal transplantation presented with a onemonthhistory of tender skin nodules on herbilateral upper extremities. A skin biopsy revealedgranulomatous inflammation in the deep dermisand the subcutaneous fat with foci of necrosis.Within the foci of necrosis were large histiocytoidstructures with prominent nuclei. Periodic acid-Schiffstain revealed a round organism with a thick capsule,consistent with amoebal trophozoites. Testing withthe Center for Disease Control revealed the organismto be Acanthamoeba...

OBJECTIVES: Surgical repair of aneurysmal disease involving the ascending aorta, aortic arch and eventually the descending aorta is generally associated with significant morbidity and mortality. A less invasive approach with the ascending wrapping technique (WT), supra-aortic vessel debranching (SADB) and thoracic endovascular aneurysm repair (TEVAR) in zone 0 was developed to reduce the associated risk in these patients. METHODS: During a 10-year period, consecutive patients treated by the ascending WT, SADB and TEVAR in zone 0 were included...

RATIONALE: Extracorporeal membrane oxygenation (ECMO) is employed for respiratory and cardiac failure in children but is complicated by bleeding and thrombosis. OBJECTIVES: (1) Measure the incidence of bleeding (blood loss requiring transfusion or intracranial hemorrhage) and thrombosis during ECMO support; (2) identify factors associated with these complications; and (3) determine the impact of these complications on patient outcome. METHODS: Prospective, observational cohort study in pediatric, cardiac, and neonatal intensive care units in eight hospitals from December 2012 to September 2014...

BACKGROUND: Dual antiplatelet therapy (DAPT), aspirin plus a P2Y12 inhibitor, is the standard antithrombotic treatment following acute coronary syndromes. The factor Xa inhibitor rivaroxaban reduced mortality and ischaemic events when added to DAPT, but caused increased bleeding. The safety of a dual pathway antithrombotic therapy approach combining low-dose rivaroxaban (in place of aspirin) with a P2Y12 inhibitor has not been assesssed in acute coronary syndromes. We aimed to assess rivaroxaban 2·5 mg twice daily versus aspirin 100 mg daily, in addition to clopidogrel or ticagrelor (chosen at investigator discretion before randomisation), for patients with acute coronary syndromes started within 10 days after presentation and continued for 6-12 months...

Sensory processing requires proper alignment of neural maps throughout the brain. In the superficial layers of the superior colliculus of the midbrain, converging projections from retinal ganglion cells and neurons in visual cortex must be aligned to form a visuotopic map, but the basic mechanisms mediating this alignment remain elusive. In a new mouse model, ectopic expression of ephrin-A3 (Efna3) in a subset of retinal ganglion cells, quantitatively altering the retinal EFNAs gradient, disrupts cortico-collicular map alignment onto the retino-collicular map, creating a visuotopic mismatch...

Covalently functionalized graphene derivatives were synthesized via benchmark reductive routes using graphite intercalation compounds (GICs), in particular KC8. We have compared the graphene arylation and -alkylation of the GIC using 4-tert-butylphenyldiazonium- and bis-(4-(tert-butyl)phenyl)-iodonium salts as well as phenyl iodide, n-hexyl- and n-dodecyl iodide as electrophiles in model reactions. We have put a particular focus on the evaluation of the degree of addition and the bulk functional-ization homogeneity Hbulk...

Reinforcement learning in simple instrumental tasks is usually modeled as a monolithic process in which reward prediction errors are used to update expected values of choice options. This modeling ignores the different contributions of different memory and decision-making systems thought to contribute even to simple learning. In an fMRI experiment, we asked how working memory and incremental reinforcement learning processes interact to guide human learning. Working memory load was manipulated by varying the number of stimuli to be learned across blocks...

PURPOSE: The purpose was to characterize acute kidney injury (AKI) in C57BL/6 (B6)- and 129/Sv (Sv)-mice by noninvasive measurement of renal perfusion and tissue edema using functional MRI. METHODS: Different severities of AKI were induced in B6- and Sv-mice by renal ischemia reperfusion injury (IRI). Unilateral clamping of the renal pedicle for 35 min (moderate AKI) or 45 min (severe AKI) was done. MRI (7-Tesla) was performed 1, 7 and 28 days after surgery using a flow alternating inversion recovery (FAIR) arterial spin labeling (ASL) sequence...

Rearrangements of anaplastic lymphoma kinase (ALK) are associated with several cancer diseases. Due to resistance development against existing ALK-inhibitors, new, structurally unrelated inhibitors are required. By a scaffold hopping strategy, 6,8-disubstituted purines were designed as analogues of similar ALK-inhibiting thieno[3,2-d]pyrimidines. While the new title compounds indeed inhibited ALK and several ALK mutants in submicromolar concentrations, they retained poor water solubility.

PURPOSE: The purpose of this study was to identify prognostic factors of patients with intrahepatic cholangiocarcinoma (ICC) treated with resection and to investigate the effect of adjuvant chemotherapy (CT). METHODS: Patients with ICC diagnosed between 2000 and 2015 treated at Hannover Medical School were included. Clinicopathologic characteristics were analyzed in univariate and multivariate analysis. In a matched pair survival analysis, patients with or without adjuvant CT were matched by these prognostic factors...

The Ehlers-Danlos syndromes (EDS) are a clinically and genetically heterogeneous group of heritable connective tissue disorders (HCTDs) characterized by joint hypermobility, skin hyperextensibility, and tissue fragility. Over the past two decades, the Villefranche Nosology, which delineated six subtypes, has been widely used as the standard for clinical diagnosis of EDS. For most of these subtypes, mutations had been identified in collagen-encoding genes, or in genes encoding collagen-modifying enzymes. Since its publication in 1998, a whole spectrum of novel EDS subtypes has been described, and mutations have been identified in an array of novel genes...

Vascular Ehlers Danlos syndrome (vEDS) is an uncommon genetic disorders characterized by arterial aneurysm, dissection and rupture, bowel rupture, and rupture of the gravid uterus. The frequency is estimated as 1/50,000-1/200,000 and results from pathogenic variants in COL3A1, which encodes the chains of type III procollagen, a major protein in vessel walls and hollow organs. Initial diagnosis depends on the recognitions of clinical features, including family history. Management is complex and requires multiple specialists who can respond to and manage the major complications...

BACKGROUND: FTC/TAF was shown to be noninferior to FTC/TDF with advantages in markers of renal and bone safety. OBJECTIVE: To evaluate the efficacy and safety of switching to FTC/TAF from FTC/TDF by third agent (boosted protease inhibitor [PI] vs. unboosted third agent). METHODS: We conducted a 48-week subgroup analysis based on third agent from a randomized, double blind study in virologically suppressed adults on a FTC/TDF-containing regimen who switched to FTC/TAF vs...
