Buyers' role in innovation procurement: Evidence from US military R&D contracts.

This study provides the first quantification of buyers' role in the outcome of R&D procurement contracts. We combine together four data sources on US federal R&D contracts, follow-on patented inventions, federal public workforce characteristics, and perception of their work environment. By exploiting the observability of deaths of federal employees, we find that managers' death events negatively affect innovation outcomes: a 1% increase in the share of relevant public officer deaths causes a decline of 32.

Unusual case of infectious endocarditis in a patient subjected to transurethral resection of the prostate (TURP) without cardiovascular risk factors.

Objective: Transurethral resection of the prostate (TURP) is the gold standard for the treatment of obstructive prostatic hyperplasia. A bacteremia leading to infectious endocarditis (IE) can be the result of urological procedures. IE post TURP is rare.

Treatment of impacted canines with aligners: An alternative and viable option.

To recover impacted canines without esthetic issues, the aligners can be a resolutive tool allowing by pontics the camouflage of absent canines during orthodontic treatment. Knowledge of biomechanics, correct staging of dental movements, and surgery planification are strategic to achieve a good result.

A non-cytotoxic regimen of decitabine to treat refractory T-cell large granular lymphocytic leukemia.

We report on a novel, successful, non-cytotoxic therapy to treat multiply-refractory T-LGL in an elderly patient.

Balancing selection, genetic drift, and human-mediated introgression interplay to shape MHC (functional) diversity in Mediterranean brown trout.

The extraordinary polymorphism of major histocompatibility complex (MHC) genes is considered a paradigm of pathogen-mediated balancing selection, although empirical evidence is still scarce. Furthermore, the relative contribution of balancing selection to shape MHC population structure and diversity, compared to that of neutral forces, as well as its interaction with other evolutionary processes such as hybridization, remains largely unclear. To investigate these issues, we analyzed adaptive (MHC-DAB gene) and neutral (11 microsatellite loci) variation in 156 brown trout ( complex) from six wild populations in central Italy exposed to introgression from domestic hatchery lineages (assessed with the LDH gene).

Toward the development of a hybrid approach to speed estimation in urban and rural areas.

Objective: Given the strong relationship between road accident and traffic speed, the evaluation and prediction of this latter have always been considered as a critical issue for road safety analysis and for the evaluation of road network safety improvements. Prediction models developed to date mainly focused on spot speed in a rural environment or on running speed in an urban one. Very few analyze the speed estimation in "transition" areas.

MitraClip After Failed Surgical Mitral Valve Repair-An International Multicenter Study.

Background Recurrence of mitral regurgitation (MR) after surgical mitral valve repair (SMVR) varies and may require reoperation. Redo mitral valve surgery can be technically challenging and is associated with increased risk of mortality and morbidity. We aimed to assess the feasibility and safety of MitraClip as a treatment strategy after failed SMVR and identify procedure modifications to overcome technical challenges.

Clinical Correlates of Functional Motor Disorders: An Italian Multicenter Study.

Background: Functional motor disorders (FMDs) are abnormal movements that are significantly altered by distractive maneuvers and are incongruent with movement disorders seen in typical neurological diseases.

Objective: The objectives of this article are to (1) describe the clinical manifestations of FMDs, including nonmotor symptoms and occurrence of other functional neurological disorders (FND); and (2) to report the frequency of isolated and combined FMDs and their relationship with demographic and clinical variables.

Methods: For this multicenter, observational study, we enrolled consecutive outpatients with a definite diagnosis of FMDs attending 25 tertiary movement disorders centers in Italy.

Circulating Long Non-Coding RNA GAS5 Is Overexpressed in Serum from Osteoporotic Patients and Is Associated with Increased Risk of Bone Fragility.

Osteoporosis (OP) is a multifactorial disorder in which environmental factors along with genetic variants and epigenetic mechanisms have been implicated. Long non-coding RNAs (lncRNAs) have recently emerged as important regulators of bone metabolism and OP aetiology. In this study, we analyzed the expression level and the genetic association of lncRNA GAS5 in OP patients compared to controls.

A case of metachronous peripheral T-Cell non-Hodgkin lymphoma following chemotherapy for Hodgkin disease successfully treated with brentuximab vedotin.

Occasionally, non-Hodgkin lymphomas (NHL) occur simultaneously or subsequently to Hodgkin disease. We report on a case of a woman with Hodgkin lymphoma treated with ABVD, who developed 4 years later T-cell NHL with both nodal and extranodal involvement. Brentuximab vedotin could be an effective choice in treating metachronous T-cell NHL.

Basal Cell Carcinoma: A Comprehensive Review.

Basal cell carcinoma (BCC) is the most common type of carcinoma worldwide. BCC development is the result of a complex interaction between environmental, phenotypic and genetic factors. However, despite the progress in the field, BCC biology and mechanisms of resistance against systemic treatments have been poorly investigated.

Clinical efficacy and reflectance confocal microscopy monitoring in moderate-severe skin aging treated with a polyvinyl gel containing retinoic and glycolic acid: An assessor-blinded 1-month study proof-of-concept trial.

Background: Retinoids and alpha-hydroxy acids are commonly used topically as anti-aging substances. Current medical devices contain retinoic acid (0.02%) and glycolic acid (4%) in a polyvinyl gel vehicle (R-G gel).

Mepolizumab effectiveness on small airway obstruction, corticosteroid sparing and maintenance therapy step-down in real life.

Background: Mepolizumab (MEP) has been recently introduced to treat severe eosinophilic asthma. Trials have demonstrated a significant effectiveness in this asthma phenotype. We evaluated MEP efficacy on lung function, symptoms, asthma exacerbations, biologic markers, steroid dependence and controller treatment level in real-life.

Incidence and Clinical Impact of Recurrent Takotsubo Syndrome: Results From the GEIST Registry.

Background Current literature only reports variable information from single-center studies on the recurrence rate, the complications, and the outcome of patients with Takotsubo syndrome ( TTS) experiencing recurrent TTS . Therefore, a detailed description of clinical characteristics, predictors, and the prognostic impact of patients with TTS and recurrences in a multicenter registry is needed. Methods and Results We analyzed 749 patients with TTS from 9 European centers being part of the international, multicenter GEIST (German Italian Stress Cardiomyopathy) Registry.

Genetic structure, phylogeography, and demography of (Bivalvia) from East Pacific as revealed by mtDNA: Implications to conservation.

Wild populations of the pustulose ark, (Bivalvia), an emblematic species of the East Pacific mangrove ecosystem declined in South American countries (Colombia, Ecuador, and Peru) mainly due to overharvesting and habitat loss or degradation. Understanding the genetic aspects of geographic variations and population structure of , currently unknown, appears as a priority to fishery authorities in order to elaborate integrated and collaborative conservation policies for fishery management, aquaculture, and stock enhancement programs. We used mtDNA sequence data to investigate haplotype diversity, genetic structure, and demography of .

First Case of Patient With Two Homozygous Mutations in and Genes Presenting With Pyogenic Bacterial Infections, Elevated IgE, and Persistent EBV Viremia.

We described for the first time a female patient with the simultaneous presence of two homozygous mutations in and genes presenting with pyogenic bacterial infections, elevated IgE, and persistent EBV viremia. In addition to defective TLR/IL1R-signaling, we described novel functional alterations into the myeloid compartment. In particular, we demonstrated a defective production of reactive oxygen species exclusively in monocytes upon stimulation, the inability of immature mono-derived DCs (iDCs) to differentiate into mature DCs (mDCs) and the incapacity of mono-derived macrophages (MDMs) to resolve BCG infection .

Italian expert panel consensus statements on two-drug antiretroviral regimens to treat naïve and virologically suppressed HIV-1 infected patients.

New strategies for HIV treatment able to reduce drug-exposure, medium-long term toxicities and costs are a recognized clinical need. The availability of newer drugs with improved potency and tolerability, as well as high genetic barrier to resistance, makes antiretroviral-sparing strategies with two-drug regimens (2DRs) particularly attractive. Substantial evidence has been generated over the last few years supporting 2DR in virologically suppressed HIV infected patients for whom a therapy switch is planned.
