Chad A Purnell, Elbert E Vaca, Marco F Ellis
BACKGROUND: Orbital exenteration is a significant reconstructive challenge for plastic surgeons. Options described for these defects range from healing by secondary intention to free tissue transfer. The authors present our preferred reconstruction of orbital defects with free forearm-based flaps, which provides quality soft tissue and orbital contouring in 1 stage to consistently allow placement of bone-anchored implants for eventual orbital prosthesis. METHODS: This conical shape of the orbit is deconstructed into a "Pac-Man" type shaped flap that leaves adequate depth for a prosthesis...

The purpose of the present study was to assess the prognostic impact of T-cadherin expression in patients with triple-negative breast cancer (TNBC). On the basis of the results of immunohistochemical analysis, 106 patients with operable TNBC were divided into two groups, the T-cadherin-positive group and T-cadherin-negative group. Fisher's exact and χ(2) tests were employed to analyze clinical data, which included the association between T-cadherin expression and clinicopathological features and prognosis...

OBJECTIVES: Practical methods for determining resting energy expenditure (REE) among individuals on maintenance hemodialysis (MHD) are needed because of the limitations of indirect calorimetry. Two disease-specific predictive energy equations (PEEs) have been developed for this metabolically complex population. The aim of this study was to compare estimated REE (eREE) by PEEs to measured REE (mREE) with a handheld indirect calorimetry device (HICD). METHODS: A prospective pilot study of adults on MHD (N = 40) was conducted at 2 dialysis clinics in Houston and Texas City, Texas...

INTRODUCTION: Clinical interventional studies in diabetes mellitus usually exclude patients undergoing peritoneal dialysis (PD). This study evaluates the impact of an educational program and a basal-bolus insulin regimen on the blood glucose level control and risk of hypoglycemia in this population. METHODS: A before-and-after study was conducted in type 1 and type 2 DM patients undergoing PD at the Renal Therapy Services (RTS) clinic network, Bogota, Colombia. An intervention was instituted consisting of a three-month educational program and a basal-bolus detemir (Levemir, NovoNordisk) and aspart (Novorapid, NovoNordisk) insulin regimen...

Many important pharmaceutical targets, such as aspartyl proteases and kinases, exhibit pH-dependent dynamics, functions and inhibition. Accurate prediction of their binding free energies is challenging because current computational techniques neglect the effects of pH. Here we combine free energy perturbation calculations with continuous constant pH molecular dynamics to explore the selectivity of a small-molecule inhibitor for β-secretase (BACE1), an important drug target for Alzheimer's disease. The calculations predicted identical affinity for BACE1 and the closely-related cathepsin D at high pH; however, at pH 4...

There is debate around the best model for diagnosing personality disorder, both in terms of its relationship to the empirical data and clinical utility. Four randomized controlled trials examining various treatments for depression were analyzed at an individual patient level. Three different approaches to the diagnosis of personality disorder were analyzed in these patients. A total of 578 depressed patients were included in the analysis. Personality disorder, however measured, was of little predictive utility in the short term but added significantly to predictive modelling of medium-term outcomes, accounting for more than twice as much of the variance in social functioning outcome as depression psychopathology...

Parents, educators, law enforcement officials, and health professionals are all concerned about the violent radicalization of adolescents. Health professionals may be called on to assess teenagers regarding the risk that they will become dangerous. We present a case in which a psychiatrist is asked to do a forensic evaluation of a young adolescent who said troubling things and had some concerning posts on his Facebook page. The evaluation reveals things about both the young boy and his community.

Positron Emission Tomography is an attractive imaging modality for monitoring the migration of cells to pathological tissue. We evaluated a new method for radiolabelling leukocytes with zirconium-89 ((89)Zr) using chitosan nanoparticles (CN, Z-average size 343 ± 210nm and zeta potential +46 ± 4mV) as the carrier. We propose that cell uptake of (89)Zr-loaded CN occurred in a two-step process; cell membrane interaction with (89)Zr-loaded CN was followed by a slower cell internalisation step.

In the 1910s, New York suffragette Electra Sparks wrote a series of essays in the Moving Picture News that advocated for cine-therapy treatments for pregnant women. Film was, in her view, the great democratizer of beautiful images, providing high-cultural access to the city's poor. These positive 'mental pictures' were important for her because, she claimed, in order to produce an attractive, healthy child, the mother must be exposed to quality cultural material. Sparks's championing of cinema during its 'second birth' was founded upon the premise of New Thought...

Reproduction is one of the most persistently generative themes in the history of science and cinema. Cabbage fairies, clones and monstrous creations have fascinated filmmakers and audiences for more than a century. Today we have grown accustomed not only to the once controversial portrayals of sperm, eggs and embryos in biology and medicine, but also to the artificial wombs and dystopian futures of science fiction and fantasy. Yet, while scholars have examined key films and genres, especially in response to the recent cycle of Hollywood 'mom coms', the analytic potential of reproduction on film as a larger theme remains largely untapped...

Tay-Sachs disease (TSD) is a fatal neurodegenerative disorder caused by a deficiency of the enzyme hexosaminidase A (HexA). Tay-Sachs disease also occurs in sheep, the only experimental model of TSD that has clinical signs of disease. The natural history of sheep TSD was characterized using serial neurological evaluations, 7 tesla MRI, echocardiograms, electrodiagnostics and cerebrospinal fluid (CSF) biomarkers. Intracranial gene therapy was also tested using AAVrh8 monocistronic vectors encoding the α subunit of Hex (TSD α) or a mixture of two vectors encoding both the α and β subunits separately (TSD α+β) injected at high (1...

Young gay men in Beirut are at significantly elevated risk of HIV infection compared with the general Lebanese population. Despite nascent HIV prevention efforts in the region, there is a need for effective community-level HIV prevention interventions tailored for young gay men. This qualitative study examined internal dynamics within Beirut's gay community as a basis for developing community-level interventions. Peer ethnographers were trained to collect field notes on conversations between young gay men in public spaces in Beirut, and conducted follow-up focus groups with young gay men...

Background. Tumor necrosis as well as tumor-associated macrophages (TAMs) in the tumor invasive front (TIF) have been suggested to have a prognostic value in selected solid tumors, inclusive hilar cholangiocarcinoma. However, little is known regarding their influence on tumor progression and prognosis in intrahepatic cholangiocarcinoma (iCC). Methods. We analyzed surgically resected tumor specimens of human iCC (n = 88) for distribution and localization of TAMs, as defined by expression of CD68, formation of necrosis and extent of peritumoral fibrosis...

BACKGROUND: Catheter ablation is now a mainstay of therapy for ventricular arrhythmias (VA). However, there are scenarios where either physiologic or anatomical factors make ablation less likely to be successful. OBJECTIVES: To demonstrate that cardiac sympathetic denervation (CSD) may be an alternate therapy for patients with difficult to ablate VA. METHODS: We identified all patients referred for CSD at a single center for indications other than LQTS and CPVT who had failed catheter ablation...

Control of parasitic gastroenteritis in cattle is typically based on group treatments with anthelmintics, complemented by grazing management, where feasible. However, the almost inevitable evolution of resistance in parasitic nematodes to anthelmintics over time necessitates a reappraisal of their use in order to reduce selection pressure. One such approach is targeted selective treatment (TST), in which only individual animals that will most benefit are treated, rather than whole groups of at-risk cattle. This study was designed to assess the feasibility of implementing TST on three commercial farms, two of which were organic...

Cardiac hypertrophy is closely linked to impaired fatty acid oxidation, but the molecular basis of this link is unclear. Here, we investigated the loss of an obligate enzyme in mitochondrial long-chain fatty acid oxidation, carnitine palmitoyltransferase 2 (CPT2), on muscle and heart structure, function, and molecular signatures in a muscle- and heart-specific CPT2-deficient mouse (Cpt2M-/-) model. CPT2 loss in heart and muscle reduced complete oxidation of long-chain fatty acids by 87% and 69%, respectively, without altering body weight, energy expenditure, respiratory quotient, or adiposity...
