REVIEW
Lulu Ma, Xuerong Yu
Arthrogryposis multiplex congenita (AMC) is a rare disorder characterized by non-progressive, multiple contractures. In addition to affected extremities, patients may also present microstomia, decreased temporomandibular joint mobility. Although the etiology of AMC is unclear, any factor that decreases fetal movement is responsible for AMC. Thus, accurate diagnosis and classification are crucial to the appropriate treatment of AMC. The development of ultrasound technology has enabled prenatal diagnosis. Very early treatment is favorable, and multidisciplinary treatment is necessary to improve the function of AMC patients...

Carboplatin is a less toxic analog of cisplatin, but carboplatin also has side effects, including bone marrow suppression. Therefore, to improve the capacity of the anticancer activity of carboplatin, we investigated whether combined treatment with carboplatin and thioridazine, which has antipsychotic and anticancer activities, has a synergistic effect on apoptosis. Combined treatment with carboplatin and thioridazine markedly induced caspase-mediated apoptosis in head and neck squamous cell carcinoma (AMC-HN4) cells...

Shuko Lee, Paromita Datta
: 245 Background: Hematologists frequently evaluate patients with leukocytosis to differentiate between benign and malignant causes. The objective of this quality improvement project was to identify risk factors for malignant leukocytosis. METHODS: A retrospective analysis of 1,330 consults in ALM VA Outpatient Hematology Clinic between 1/1/2011 and 2/22/2015 was performed. 147 patients referred for evaluation of leukocytosis were included in this study. The following data was collected: sex, age, race, ethnicity, BMI, tobacco use, total WBC, tempo of leukocytosis (constant vs intermittent), Hg level, plt count, ANC, ALC, AMC, AEC, ABC, laboratory tests performed during work-up, final diagnosis (primary hematologic malignancy vs secondary causes)...

: 3 Background: Cancer centers across the country are largely unprepared to move toward value-based payment. Total cost of care data is not readily available and centers do not know how much of their patients' care is received at other hospitals, when in the trajectory of illness greatest cost is incurred, or the elements of care that present the greatest opportunity for savings. A previous examination of practice patterns Smilow Cancer Hospital (SCH) demonstrated that our patients had high rates of ED visits, hospital admissions and ICU use in their last month of life...

Academic medical centers (AMCs) are widely perceived as providing the highest-quality medical care. To investigate disparities in access to such care, we studied the racial/ethnic and payer mixes at private AMCs of New York City (NYC) and Boston, two cities where these prestigious institutions play a dominant role in the health care system. We used individual-level inpatient discharge data for acute care hospitals to examine the degree of hospital racial/ethnic and insurance segregation in both cities using the Index of Dissimilarity, together with recent changes in patterns of care in NYC...

Enhanced catalytic activity (super activity) of enzymes in the presence of surfactants is of key importance in "micellar enzymology"; such super activity is not very trivial, it is highly system specific, and the mechanism behind the activity enhancement is not always well apprehended. We report the catalytic activity of α-chymotrypsin (CHT) on ala-ala-phe-7-amido-4-methylcoumarin (AMC) in the presence of cationic surfactants of different hydrophobic chain lengths: dodecyltrimethylammonium bromide (DTAB), cetyltrimethylammonium bromide (CTAB) and octadecyltrimethylammonium bromide (OTAB)...

PURPOSE: Distinguishing infiltrative renal cell carcinoma (RCC) from transitional cell carcinoma (TCC) is a challenging issue due to their radiologic similarities. We evaluated systemic inflammatory biomarkers as parameters for distinguishing tumor types. MATERIALS AND METHODS: A computerized search of medical records from November 2005 to October 2015 identified 116 patients with infiltrative renal masses who were difficult to diagnose confirmatively in radiological study...

Difficulties related to the obtainment of stem/progenitor cells from skeletal muscle tissue make the search for new sources of myogenic cells highly relevant. Alveolar mucosa might be considered as a perspective candidate due to availability and high proliferative capacity of its cells. Human alveolar mucosa cells (AMC) were obtained from gingival biopsy samples collected from 10 healthy donors and cultured up to 10 passages. AMC matched the generally accepted multipotent mesenchymal stromal cells criteria and possess population doubling time, caryotype and immunophenotype stability during long-term cultivation...

BACKGROUND: Arthrogryposis syndromes are a heterogeneous group of disorders characterized by congenital joint contractures often requiring multiple surgeries during childhood to address skeletal and visceral abnormalities. Previous reports suggest that these children have increased perioperative risk, including hypermetabolic events discrete from malignant hyperthermia, difficult airway management, isolated hyperthermia, and difficult IV line placement. We sought to compare children with arthrogryposis multiplex congenita (AMC) versus the less severe, distal arthrogryposis syndromes (DAS) and to evaluate possible intraoperative hyperthermia of patients with AMC...

During the period January 2013-December 2015, 175 cases of human salmonellosis were reported in the Apulia Region of Italy. The aim of this study was to characterize salmonella strains from the standpoints of serovars prevalence, antimicrobial resistance and clonal origin. The serological typing was performed by agglutination against antisera followed by a multiplex polymerase chain reaction (m-PCR). The obtained results were analyzed following the Kauffmann-White scheme. Susceptibility to antimicrobial agents was tested using the disk diffusion method on Muller-Hinton agar plates...

BACKGROUND: Faculty departure can present significant intellectual costs to an institution. The authors sought to identify the reasons for clinical and non-clinical faculty departures at one academic medical center (AMC). METHOD: In May and June 2010, the authors surveyed 137 faculty members who left a west coast School of Medicine (SOM) between 1999 and 2009. In May and June 2015, the same survey was sent to 40 faculty members who left the SOM between 2010-2014, for a total sample size of 177 former faculty members...

A study of four representative actinide monocarbides, ThC, UC, PuC, and AmC, has been performed with relativistic quantum chemical calculations. The two applied methods were multireference complete active space second-order perturbation theory (CASPT2) including the Douglas-Kroll-Hess Hamiltonian with all-electron basis sets and density functional theory with the B3LYP exchange-correlation functional in conjunction with relativistic pseudopotentials. Beside the ground electronic states, the excited states up to 17 000 cm(-1) have been determined...

PURPOSE: Hyperthermia combined with Mitomycin C is used for the treatment of non-muscle invasive bladder cancer (NMIBC), using a phased array system of microwave antennas for bladder heating. Often some air is present in the bladder, which effectively blocks the microwave radiation, potentially preventing proper treatment of that part of the bladder. Air can be a relevant fraction of the bladder content and large air pockets are expected to have a noticeable influence on achieved temperatures...

We report the case of a newborn with arthrogryposis multiplex congenita and severe axial hypotonia without cardiac involvement in which, using a customized targeted next-generation sequencing assay for 64 myopathy-associated genes, we detected a novel homozygous truncating mutation, c.38661_38665del, in exon 197 of the TTN gene that is expressed only in the fetal skeletal isoform. Its pathogenicity is supported by evidence of maternal isodisomy for chromosome 2. Muscle pathology showed fibers with core-like areas devoid of oxidative staining and cytoplasmic bodies...

Zixiao Zhang, Wuyou Jiang, Donghui Long, Jitong Wang, Wenming Qiao, Licheng Ling
A general synthesis of alkaline mesoporous carbons (AMCs) is developed based on a simplified silica-templating method for room-temperature catalytic oxidation of H2S. The key to the success relies on dissolving the silica templates to create the interconnected mesoporous structure as well as leaving parts of the alkaline products in the pores; both of them are prerequisites for H2S oxidation. By adjusting the alkaline etching degree and organic/inorganic ratio, the porosity and basicity of the AMC could be simultaneously tuned, allowing the AMCs direct use for H2S catalytic oxidation with an unprecedented removal capacities of 4...

The purpose of this study was to examine the measurement properties of the Assessing Math Concepts AMC Anywhere Hiding and Ten Frame Assessments, formative assessments of primary students' number sense skills. Each assessment has two parts, where Part 1 is intended to be foundational skills for part two. Part 1 includes manipulatives whereas Part 2 does not. Student data from 228 kindergarten through second grade teachers with a total of 3,666 students was analyzed using Rasch scaling. Data analyses indicated that when the two assessments were examined separately the intended order of item difficulty was clear...

The recent alarming statements concerning the newborn ZIKV-induced microcephaly epidemics in the Northeast of Brazil, released by the Brazilian Ministry of Health, as well as important international health agencies, such as the World Health Organization and the Pan American Health Organization, raised many "why and how" questions so far, that will hopefully be scientifically answered, as more researches in that regard come up in the long term. In this paper, we describe another potentially ZIKV-induced central nervous system and musculoskeletal disorder that has accompanied microcephaly in these children: atrhogryposis multiplex congenita...

We report a case of rat bite fever (RBF) diagnosed by detection of Streptobacillus moniliformis from blood culture and synovial fluid. The patient was a 45-year-old man with alcoholic liver cirrhosis. He was bitten on his third finger by a rat, which was caught in a mousetrap installed in his house. After the bite, fever, rash and arthralgia developed over a period of about two weeks. The patient was admitted to our hospital and treated with combination of Ampicillin- Sulbactam (SAM), Vancomycin (VAN) and Minocycline (MIN)...
