Next generation sequencing for personalized therapy: About a class III BRAF N581K mutation associated to NRAS Q61L mutation in malignant melanoma: Case report.

In metastatic stage, therapeutic approach for malignant melanoma is particularly based on performance status, metastatic sites, and status (/ or (class I mutations). In most cases, mutations and mutations are mutually exclusive to each other. However, some rare mutations class III are preferentially associated with a mutation, leading to the MAP Kinase pathway activation and subsequent cell proliferation.

Development of a robust and quantitative high-throughput screening method for assessing phenotypic variation in large isolate collections.

Genome-wide association studies are a powerful approach for identifying determinants of disease. For infectious diseases, high throughput assays are required for measuring the variance in multiple virulence-related phenotypes of large bacterial isolate collections and for association of this phenotypic variance with genotype. The primary limiting factors are cost, effectiveness and a standardized inoculum.

Antibody dependent cell cytotoxicity is maintained by the unmutated common ancestor of 6F5, a Gp41 conformational epitope targeting antibody that utilizes heavy chain VH1-2.

In studies on monoclonal IgG antibodies (mAbs) from long-term non-progressors (LTNPs), our laboratory has previously described highly mutated Abs against a complex conformational epitope with contributions from both gp41 the N terminal and C terminal heptad repeat helices. Despite using the VH1-2 gene segment, known to contribute to some of the broadest neutralizing Abs against HIV, members of these Abs, termed group 76C Abs, did not exhibit broad neutralization. Because of the high number of mutations and use of VH1-2, our goal was to characterize the non-neutralizing functions of Abs of group 76C, to assess if targeting of the epitope correlates with LTNP, and to assess the maturation of these Abs by comparison to their predicted common ancestor.

Chemotherapy-induced cachexia and model-informed dosing to preserve lean mass in cancer treatment.

Although chemotherapy is a standard treatment for cancer, it comes with significant side effects. In particular, certain agents can induce severe muscle loss, known as cachexia, worsening patient quality of life and treatment outcomes. 5-fluorouracil, an anti-cancer agent used to treat several cancers, has been shown to cause muscle loss.

cavitary lung disease progression over a three year period - A case report.

is a slow growing non-tuberculous mycobacterium associated with rare but severe infections. It most commonly presents as pulmonary disease in people with underlying structural lung disease. We report a case of progressive cavitary lung disease over a three year period due to and the subsequent outcome.

Gender and Age Related Differences in Leg Stiffness and Reactive Strength in Adolescent Team Sports Players.

The aim of the present study was to identify potential gender differences in leg stiffness and reactive strength during hopping tasks in 13 to16-year old team sports players. Reactive strength index (RSI) and leg stiffness were obtained in two consecutive seasons from 51 girls (U14: n = 31, U16: n = 20) and 65 boys (U14: n = 32, U16: n = 33). A significant main effect on absolute (U14: p = 0.

Serum Responses of Children With Kawasaki Disease Against Severe Acute Respiratory Syndrome Coronavirus 2 Proteins.

With recent reports showing clinical and laboratory overlap of multisystem inflammatory syndrome in children and Kawasaki disease (KD), we addressed the hypothesis that cross coronavirus humoral immunity leads to a parallel postinfectious phenomenon explaining similar pathologic findings in KD and multisystem inflammatory syndrome in children. We demonstrated no cross-reactivity in children with KD but observed some nonspecific interactions postintravenous immunoglobulin infusion.

Utility of Methicillin-Resistant Staphylococcus aureus Nares Screening for Patients with a Diabetic Foot Infection.

Treatment of suspected methicillin-resistant (MRSA) is a cornerstone of severe diabetic foot infections; however, antibiotics can be associated with toxicity. The objective of this study was to determine the negative predictive value (NPV) of MRSA nares screening in the determination of subsequent MRSA in patients with a diabetic foot infection. This was a retrospective cohort study across Veterans Affairs (VA) medical centers from 1 January 2007 to 1 January 2018.

Changes in Injury Risk Mechanisms after Soccer-Specific Fatigue in Male Youth Soccer Players.

The aim of this study was to examine the acute effects of soccer specific fatigue on muscular and neuromuscular function in male youth soccer players. Elite soccer players (n = 20; age 15.7 ± 0.

The Missing Record of Mental Status in Written Sign-Outs.

Objective: The aim of the study was to determine how frequently mental status and mental status changes are documented in the written patient summary ("sign-out") provided to covering physicians.

Patients And Methods: This was a retrospective cohort study of general medical patients hospitalized between March 16, 2009, and March 15, 2010, conducted at 2 teaching hospitals. Participants included patients with mental status change adverse events (MSAEs) and their providers.

Consistency of Field-Based Measures of Neuromuscular Control Using Force-Plate Diagnostics in Elite Male Youth Soccer Players.

J Strength Cond Res 30(12): 3304-3311, 2016-Deficits in neuromuscular control during movement patterns such as landing are suggested pathomechanics that underlie sport-related injury.

Pediatric Opsoclonus-Myoclonus-Ataxia Syndrome Associated With Anti-N-methyl-D-aspartate Receptor Encephalitis.

Background: The full clinical spectrum of anti-N-methyl-D-aspartate receptor encephalitis is unknown in the pediatric population.

Patient: We describe a previously healthy 4-year-old girl presenting with opsoclonus-myoclonus together with ataxia who had NR1-specific, anti-N-methyl-D-aspartate receptor antibodies in the cerebral spinal fluid.

Conclusion: The presence of NR1-specific, anti-N-methyl-D-aspartate receptor antibodies in the setting of opsoclonus-myoclonus and ataxia syndrome may represent an expansion of the clinical presentations of anti-N-methyl-D-aspartate receptor encephalitis.

'Nordic' hamstrings exercise - engagement characteristics and training responses.

The present study examined the neuromuscular activation characteristics of the hamstrings during the 'Nordic' hamstrings exercise (NHE) and changes in the eccentric strength of the knee flexors with NHE training. Initially, the normalised root mean square electromyographic (EMG) activity of the hamstrings of both limbs during various phases (90-61°, 60-31° and 30-0° of knee extension) of the NHE were determined in 18 soccer players. Subsequently participants were randomly allocated to either a training (n=10) or control group.

Advances in paediatric strength assessment: changing our perspective on strength development.

Our knowledge of the age and sex associated changes in strength during childhood and adolescence is relatively limited compared to other physiological parameters. However, those studies available on the age and sex associated change in strength are relatively consistent, especially for the lower limbs. Caution must be taken when transferring this knowledge to other muscle joints as the development in strength appears to be both muscle action and joint specific.
