Age (61+), Black race, hypertension, sepsis, and cancer were significant for all 4 procedures.

Several factors are independently associated with extended LOS for those undergoing the most common EGS procedures. Five of these were associated with an increased LOS for all four procedures. These included, age (61+), hypertension, sepsis, cancer, and Black race.

Ataxia-telangiectasia (A-T) is a rare autosomal recessive syndrome characterized by progressive cerebellar ataxia, oculocutaneous telangiectasia, variable immunodeficiency, radiosensitivity, and cancer predisposition. Mutations cause A-T in the

(

) gene encoding a serine/threonine-protein kinase.

The authors reviewed the literature on PubMed, Web of Science, and Scopus databases to collect comprehensive data related to A-T. This review aims to discuss various update aspects of A-T, including epidemiology, pathogenesis, clinical manifestations, diagnosis, prognosis, and management.

A-T as a congenital disorder has phenotypic heterogeneity, and the severity of symptoms in different patients depends on the severity of mutations. This review provides a comprehensive overview of A-T, although some relevant questions about pathogenesis remain unanswered, probably owing to the phenotypic heterogeneity of this monogenic disorder. The presence of various clinical and immunologic manifestations in A-T indicates that the identification of the role of defective ATM in phenotype can be helpful in the better management and treatment of patients in the future.

Solid-phase denitrification (SPD) is a technology that has attracted in recent years increasing attention due to its significant advantage suitability over the aqueous-based denitrification for in situ water remediation. This paper provides a view of new aspects of the application of SPD for water remediation. read more The processes and mechanisms for nitrogen transformation in SPD, for example, direct denitrification, dissimilatory nitrate reduction to ammonium, and anammox are presented. The main processes of the transformation of the carbon substrate in SPD are also discussed. The major limitations of SPD, including low carbon availability, NO2- and N2O accumulation, dissolved organic carbon release, and NH4+ production, are summarized and the factors associated with such limitations are also discussed. In addition, some novel measures to mitigate these limitations, such as applying a biodegradable polymer substrate and heterotrophic-autotrophic denitrification (HAD) process, are described. Finally, simultaneous removal of nitrate and some typical concurrent contaminants for expanded application of SPD are discussed. This review attempts to advance our understanding of engineered denitrification processes for wastewater treatment or water remediation.Introduction Contemporary, flexible stone baskets are unable to extract submillimeter stone fragments at the time of ureteroscopic laser lithotripsy. In this in vitro study, the feasibility of suctioning submillimeter fragments with a standard Luer Lock syringe through the working channel of a flexible ureteroscope was assessed. Materials and Methods Phantom stones made from industrial plaster were mechanically fragmented into ≤1 and ≤0.5-mm groups. Both stone groups were divided into five preweighed trial samples. Each stone group was then mixed in a beaker filled with normal saline. A standard 10-mL Luer Lock syringe was connected to a fiber-optic ureteroscope with a 1.2-mm working channel. The syringe was then used to suction stone fragments from the beaker. The suctioned stone fragments and the stone fragments remaining in the beaker after removing the overlying solution were separated, centrifuged with supernatant removed, and dried in an incubator set at 33°C for 1 week. Dried weights were recorded. Results Mean total weights for ≤0.5 and ≤1.0-mm stone groups at baseline were 0.807 and 0.806 g, respectively. The mean percentages of stone fragments suctioned through the ureteroscope for ≤0.5 and ≤1.0-mm groups were 86% and 86%, respectively (p = 0.973). During suctioning, 64% of stones in the ≤0.5-mm group were trapped in either the working channel of the ureteroscope or within the Luer Lock syringe compared with 78% of stones in the ≤1-mm group (p = 0.001) requiring cessation of the procedure to clear the channel. Conclusions It is feasible to suction submillimeter stone fragments by connecting a Luer Lock syringe to the working channel of a flexible ureteroscope. The limiting factor for removing stone fragments appears to be the small working channel of flexible ureteroscopes as trapping of fragments during suctioning is common and requires time-consuming removal of the endoscope and clearing of the channel.

Glioblastoma multiforme is the most common and the most aggressive primary brain tumor, with a median survival of 14months. This dismal prognostic has turned research toward nanomedicine as a new therapeutic approach that can deliver therapeutic compounds to GBM.

The review covers recent advances in the targeted delivery of therapeutic compounds to glioblastoma tumors. To reach the tumors, nanocarriers and their cargo should cross the Blood-Brain Barrier (BBB) standing between the bloodstream and the tumor. For that purpose, different peptides to facilitate BBB crossing have been added to the nanoparticles. As result, an increase in BBB crossing was observed. Other significant effort has been devoted to selectively target direct the nanocarrier and its cargo to GBM tumors. Once again, targeting peptides have been used.

Besides significant advances, a more successful design of nanocarriers for efficient BBB crossing and delivery of diagnostic and/or therapeutic molecules to CNS will be needed to achieve efficient nanomedicine-based therapeutics for glioblastoma.
