Abstract
BACKGROUND Data are lacking on adherence to Centers for Disease Control and Prevention testing guidelines among insured US women presenting with vaginal health complaints; thus, we quantified vaginitis testing frequency and assessed the co-testing rate for causes of vaginitis and Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG). METHODS This was a retrospective analysis of de-identified data from a medical database. Information from women, ages 18-50 years, was obtained from the Truven MarketScan Commercial Database (2012-2017) using Current Procedural Technology codes; chi-square testing was applied to determine co-testing differences for CT/NG based on vaginitis test type. Odds ratios were calculated to determine the association with CT/NG screening across vaginitis testing categories. RESULTS Approximately 48% of 1,359,289 women received a vaginitis diagnosis that involved a laboratory-based test. Of these women only 34% were co-tested for CT/NG. CT/NG co-testing was highest for those with nucleic acid amplification testing for vaginitis and lowest for those with no vaginitis testing Current Procedural Technology code (respectively, 71% vs 23%, P < 0.0001). CONCLUSIONS The vaginitis nucleic acid amplification test, indicated by CPT code, was associated with statistically significant, higher CT/NG testing rates. Molecular diagnostics may support vaginitis testing in settings that have limited opportunities for microscopy and clinical exams and offer greater opportunity to offer comprehensive women's healthcare that includes testing for chlamydia and/or gonorrhea infections.

Abstract
PURPOSE To determine the outcomes of the Association of American Medical Colleges (AAMC) Council of Deans (COD) Fellowship Program with respect to participants' achieving the goals of becoming a medical school dean and developing leadership skills, and to ascertain fellows' views about the program's value, beneficial aspects, and areas for improvement. METHOD The 37 COD fellows from 2002 to 2016 were invited to participate in a 2017 survey addressing demographics, training, current leadership position, and value of the program. The survey also included 3 open-ended questions. A 2018 web-based search was conducted to determine fellows' senior leadership roles since their program participation. RESULTS The survey response rate was 73% (27/37). The majority of respondents were male (82%, 22), aged 51-70 (89%, 25), and white (82%, 22). The top 5 medical specialties reported were internal medicine, pediatrics, anesthesiology, psychiatry, and surgery. Most respondents (63%, 17) reported having a graduate degree. All reported being in leadership positions in academia and/or health care. The web-based search found that 27% (10/37) of the fellows became medical school deans (average tenure 5.6 years); 2 fellows became deans of other types of schools. Overall, survey respondents perceived the program as valuable. Respondents identified shadowing a dean mentor, attending COD meetings, and attending the AAMC Executive Development Seminar for Deans as the most valuable program components. The majority (88%, 23/26) indicated their fellow experience persuaded them to pursue being a dean; 2 (8%) indicated it did not. Respondents identified 4 key opportunities for program improvement: more sponsorship by deans, development of a learning community, enhanced mentoring, and coaching. CONCLUSIONS The COD Fellowship Program appears to be successful in preparing senior faculty to become deans and assume other senior leadership roles in academia and/or health care. Fellows' feedback will be used to inform future revisions to the program.

Abstract
Objective: The aim of this study was to examine the prevalence of bandemia in confirmed respiratory viral infections in febrile infants and children presenting to the emergency department. Methods: An observational retrospective study from January 1, 2016, through December 31, 2016, was conducted in patients between the ages of ≥ 1 month and ≤ 5 years presenting to the emergency room with fever and who had a complete blood cell count performed. Patients were separated into seven groups based on the type of respiratory viral infection. Inclusion criteria strictly counted children with viral infections and absence of clinical and laboratory evidence of a bacterial coinfection. Results: A total of 419 patients had a documented viral infection. A significant proportion of these children were found to have bandemia; children with adenovirus (17%), respiratory syncytial virus (RSV) (14.9%), human metapneumovirus (hMPV) (13%), and parainfluenza virus (7.9%) had the highest prevalence when the cutoff for bandemia was set at 10%. The prevalence increased to 35.3, 30.9, 40.3, and 15.8% for adenovirus, RSV, hMPV, and parainfluenza virus, respectively, when this cutoff was lowered further to 5%. Conclusion: Band neutrophils are detected frequently in confirmed respiratory viral infections particularly during early stages.

Abstract
Individuals with debilitating facial injuries and deformities have achieved significant improvement of aesthetic form and function after undergoing a face transplantation. The involvement of surgical technologists and perioperative nurses in the care of the recipient and donor plays a critical role in the success of these procedures. There are unique challenges that staff members may be presented with when caring for a donor and recipient undergoing a face transplantation, including less comfort with and knowledge of the surgical procedure and instrumentation, an increased amount of equipment and personnel in the OR, donor and recipient admission and discharge care, and increased shift length. At New York University Langone Medical Center, New York, we have developed a comprehensive process to prepare staff members to care for patients undergoing face transplantation.

Abstract
To date, more than 30 face transplants have been performed worldwide. This innovative procedure has restored the functional and aesthetic aspects of the face in patients with cancer, congenital, and trauma-related deformities where the results of traditional reconstructive surgery have been deficient. The importance of nursing involvement in the care of these patients is undeniable; however, little has been published about how to properly prepare a nursing department to undertake such an important role. Although the care of patients undergoing face transplants has many similarities to the care of patients undergoing traditional head and neck flap procedures, patients undergoing face transplant provide unique challenges, including immunosuppression, allograft rejection, communication impairment, and psychosocial needs. Staff at New York University's Langone Medical Center have devised a specific plan of action to properly inform, educate, and prepare the nursing staff for this exciting endeavor.

Abstract
BACKGROUND The majority of deleterious health consequences of coeliac disease (CD) are most likely to be secondary to intestinal inflammation; hence, mucosal recovery is a desirable goal of therapy. Follow-up in CD is controversial and serological response is often used as a surrogate for histological recovery. AIMS To inform the clinical management of CD using comparative serological and histological data from a biopsy-driven pathway of care. METHODS A retrospective analysis of the Cambridge Coeliac Clinic database of 595 patients routinely followed up by biopsy and serology. RESULTS Paired biopsy results were available for 391 patients (15% seronegative). Persisting villous atrophy (VA) occurred in 182 patients (47%). The sensitivity of anti-tissue transglutaminase (TTG) antibody for ongoing VA was only 43.6%. Information on dietetic management and further biopsy to assess response was available for 94 initially unresponsive patients, in whom targeted dietetic intervention by removal of identified gluten sources or avoidance of trace amounts of gluten led to resolution of persistent VA in 50%. The effects of institution of a formal care pathway are analysed in 298 patients. Discharge to primary care and clinical management was facilitated by the information derived from repeat biopsy. CONCLUSIONS Serology appears to be a poor surrogate marker for mucosal recovery on a gluten-free diet; dietary assessment fails to identify a potential gluten source in many patients with ongoing villous atrophy. The benefits of re-biopsy on diet include stratification of patients with coeliac disease suitable for early discharge from secondary care or those requiring more intensive clinical management.

Abstract
Anaesthetists may subject patients to unnecessary risk by not checking anaesthetic equipment thoroughly before use. Numerous adverse events have been associated with failure to check equipment. The Australian and New Zealand College of Anaesthetists and anaesthetic delivery system manufactures have made recommendations on how anaesthetic equipment should be maintained and checked before use and for the training required for staff who use such equipment. These recommendations are made to minimise the risk to patients undergoing anaesthesia. This prospective audit investigated the adherence of anaesthetic practitioners to a selection of those recommendations. Covert observations of anaesthetic practitioners were made while they were checking their designated anaesthetic machine, either at the beginning of a day's list or between cases. Structured interviews with staff who check the anaesthetic machine were carried out to determine the training they had received. The results indicated poor compliance with recommendations: significantly, the backup oxygen cylinders' pressure/contents were not checked in 45% of observations; the emergency ventilation device was not checked in 67% of observations; the breathing circuit was not tested between patients in 79% of observations; no documentation of the checks performed was done in any cases; and no assessment or accreditation of the staff who performed these checks was performed. It was concluded that the poor compliance was a system failing and that patient safety might be increased with training and accrediting staff responsible for checking equipment, documenting the checks performed, and the formulation and use of a checklist.

Abstract
Filters rated as having a 0.2-microm pore size (0.2-microm-rated filters) are used in laboratory and manufacturing settings for diverse applications of bacterial and particle removal from process fluids, analytical test articles, and gasses. Using Hydrogenophaga pseudoflava, a diminutive bacterium with an unusual geometry (i.e., it is very thin), we evaluated passage through 0.2-microm-rated filters and the impact of filtration process parameters and bacterial challenge density. We show that consistent H. pseudoflava passage occurs through 0.2-microm-rated filters. This is in contrast to an absence of significant passage of nutritionally challenged bacteria that are of similar size (i.e., hydrodynamic diameter) but dissimilar geometry.

Abstract
Advanced prostate cancer is not curable by current treatment strategies indicating a significant need for new chemotherapeutic options. Highly substituted ansa-titanocene compounds have shown promising cytotoxic activity in a range of cancers. The objectives of this study are to examine the effects of these titanocene compounds on prostate cancer cells. Prostate cell lines were treated with three novel titanocene compounds and compared to titanocene dichloride and cisplatin. Percent apoptosis, viability and cell cycle were assessed using propidium iodide DNA incorporation with flow cytometry. Cytochrome C was assessed by western blotting of mitochondrial and cytoplasmic fractions. Apoptosis Inducing Factor was assessed by confocal microscopy. These novel compounds induced more apoptosis compared to cisplatin in a dose dependent manner. Compound Y had the most significant effect on cell cycle and apoptosis. Despite the release of cytochrome C from the mitochondrial fraction there was no inhibition of apoptosis with the pan caspase inhibitor, ZVAD-FMK. AIF was shown to translocate from the cytosol to the nucleus mediating a caspase independent cell death. Bcl-2 over expressing PC-3 cells, which were resistant to cisplatin induced apoptosis, underwent apoptosis following treatment with all the titanocene compounds. This study demonstrates possible mechanisms by which these novel titanocene compounds can mediate their apoptotic effect in vitro. The fact that they can induce more apoptosis than cisplatin in advanced cancer cell lines would confer an advantage over cisplatin. They represent exciting new agents with future potential for the treatment of advanced prostate cancer.

Abstract
Membrane-associated guanylate kinases (MAGUKs) assemble protein complexes at sites of cell-cell contact. At excitatory synapses in brain, MAGUKs localize to the postsynaptic density (PSD) and interact with N-methyl-D-aspartate (NMDA) glutamate receptors and downstream signaling proteins. However, NMDA receptors are not restricted to the PSDs, as electron microscopic immunocytochemical (EM-ICC) results indicate that NMDA receptors also occur at nonsynaptic portions of dendrites, perhaps functioning as reserves for rapid insertion into synaptic membranes in response to appropriate synaptic activity. NMDA receptors also occur in axons, at least in part to support glutamate-dependent enhancement of transmitter release. In this study, a systematic EM-ICC survey was performed to determine whether the distributions of four neuronal MAGUKs-PSD-95, PSD-93, SAP-102, and SAP-97-resemble that of NMDA receptors. Quantitative analysis revealed that the density of PSD-95 over thick PSDs of asymmetric axo-spinous synaptic junctions is 2-3-fold the level in the immediately adjacent cytoplasm of spines and terminals, while symmetric synapses show no association with PSD-95. Similarly, all four MAGUKs occur over PSDs of spines. However, we also detected MAGUK immunoreactivity, albeit more diffusely, along presynaptic membranes and in the cytoplasm of axons and dendritic shafts. In fact, the overall distribution of PSD-95 within the neuropil is equally prevalent along plasma membranes (including synaptic portions) as in the cytoplasm, away from plasma membranes. These results suggest that MAGUKs have dual roles: to maintain receptors at synapses and to regulate shuttling of receptors between nonsynaptic and synaptic sites.

Abstract
Proteins containing PDZ (postsynaptic density-95, discs large, zonula occludens) domains play a general role in recruiting receptors and enzymes to specific synaptic sites. In Caenorhabditis elegans, a complex of three PDZ proteins, LIN-2/7/10, mediates basolateral targeting of a receptor tyrosine kinase. Homologs of these LIN proteins have also been identified in higher organisms, and here we analyze the MALS/Veli (mammalian LIN-7/vertebrate homolog of LIN-7) proteins in brain. Immunohistochemical staining and in situ hybridization show that MALS occur differentially in discrete populations of neurons throughout the brain. Most neurons express only one MALS protein, although some cells contain two or even all three MALS isoforms. At the subcellular level, MALS proteins are found in both dendritic and axonal locations, suggesting that they may regulate processes at both pre- and postsynaptic sites. Targeted disruption of MALS-1 and MALS-2 does not yield a detectable phenotype, and hippocampal synaptic function and plasticity are intact in the MALS-1/2 double knockouts. Interestingly, MALS-3 protein is dramatically induced in the MALS-1/2 double knockouts, implying that dynamic changes in protein expression may play an important regulatory role for this family of synaptic PDZ proteins.
