Glioblastoma (GBM) is an aggressive primary brain tumor depicted by a cold tumor microenvironment, low immunogenicity, and limited effective therapeutic interventions. Its location in the brain, a highly immune-selective organ, acts as a barrier, limiting immune access and promoting GBM dissemination, despite therapeutic interventions. Currently, chemotherapy and radiation combined with surgical resection are the standard of care for GBM treatment.

Mesial temporal lobe epilepsy (mTLE) is an important cause of drug-resistant epilepsy (DRE) in adults and children. Traditionally, the surgical option of choice for mTLE includes a frontotemporal craniotomy and open resection of the anterior temporal cortex and mesial temporal structures. Although this technique is effective and durable, the neuropsychological morbidity resulting from temporal neocortical resections has resulted in the investigation of alternative approaches to resect the mesial temporal structures to achieve seizure freedom while minimizing postoperative cognitive deficits.

Introduction: Insurance prior authorization (PA) is a determination of need, required by a health insurer for an ordered test/procedure. If the test/procedure is denied, a peer-to-peer (P2P) discussion between ordering provider and payer is used to appeal the decision. The objective of this study was to measure the number and patterns of unnecessary PA denials.

In previous studies, we demonstrated that panobinostat, a histone deacetylase inhibitor, and bortezomib, a proteasomal inhibitor, displayed synergistic therapeutic activity against pediatric and adult high-grade gliomas. Despite the remarkable initial response to this combination, resistance emerged. Here, in this study, we aimed to investigate the molecular mechanisms underlying the anticancer effects of panobinostat and marizomib, a brain-penetrant proteasomal inhibitor, and the potential for exploitable vulnerabilities associated with acquired resistance.

In nature, bacteria can form biofilms, multi-layered structures that adhere microbial populations to solid surfaces by exopolysaccharides, proteins, and nucleic acids. In addition to causing foodborne infections, biofilms can be a major problem in aquaculture. Actinomycetes extracts have previously demonstrated antibiofilm activity against multiple foodborne and fish pathogens, and further characterization of these extracts is needed.

American Indian/Alaska Native (AI/AN) persons experienced disproportionate mortality during the 2009 influenza A(H1N1) pandemic (1,2). Concerns of a similar trend during the coronavirus disease 2019 (COVID-19) pandemic led to the formation of a workgroup* to assess the prevalence of COVID-19 deaths in the AI/AN population. As of December 2, 2020, CDC has reported 2,689 COVID-19-associated deaths among non-Hispanic AI/AN persons in the United States.

Article Synopsis
  • * During a facility-wide testing initiative from March to June 2020, seven health departments tested nearly 23,000 individuals in 288 nursing homes, revealing that 0.4% of tested persons in low-incidence areas and 12% in targeted facilities were positive for COVID-19.
  • * The study showed that timely facility-wide testing following the identification of the first COVID-19 case could uncover additional infections and enhance infection control measures, indicating a critical need for rapid response in nursing home settings.

Although coccidioidomycosis in Arizona and California has been well-characterized, much remains unknown about its epidemiology in states where it is not highly endemic. We conducted enhanced surveillance in 14 such states in 2016 by identifying cases according to the Council of State and Territorial Epidemiologists case definition and interviewing patients about their demographic characteristics, clinical features, and exposures. Among 186 patients, median time from seeking healthcare to diagnosis was 38 days (range 1-1,654 days); 70% had another condition diagnosed before coccidioidomycosis testing occurred (of whom 83% were prescribed antibacterial medications); 43% were hospitalized; and 29% had culture-positive coccidioidomycosis.

Background: Medically unexplained loss or alteration of voice-functional dysphonia-is the commonest presentation to speech and language therapists (SLTs). Besides the impact on personal and work life, functional dysphonia is also associated with increased levels of anxiety and depression and poor general health. Voice therapy delivered by SLTs improves voice but not these associated symptoms.

Lyme borreliosis (LB) is a multisystem disease caused by spirochetes in the Borrelia burgdorferisensu lato (Bbsl) genospecies complex. We previously described a novel Bbsl genospecies (type strain MN14-1420T) that causes LB among patients with exposures to ticks in the upper midwestern USA. Patients infected with the novel Bbsl genospecies demonstrated higher levels of spirochetemia and somewhat differing clinical symptoms as compared with those infected with other Bbsl genospecies.

Purpose Of Review: The improving access to psychological therapies initiative has highlighted the importance of managing mental health problems effectively, and research has shown excellent outcomes from cognitive behavioural therapy (CBT) interventions. Patients presenting with functional dysphonia will often also describe psychological distress including anxiety, depression and reduced general well-being, and it is felt that effective voice therapy needs to include the management of psychological well-being. The evidence for the use of CBT enhanced voice therapy is limited to date.

Purpose Of Review: Functional dysphonia, defined as alteration or loss of voice in the absence of physical pathology, is known to be associated with a variety of psychosocial factors including anxiety, depression and reduced quality of life. Models of functional dysphonia have tended to conceptualize the voice disorder as being the result of a failure to acknowledge and/or express this associated distress. The current literature was reviewed to identify psychosocial factors that predispose to, precipitate and perpetuate functional dysphonia and to assess the evidence for these models.

Within healthcare institutions, leadership is an essential driver of expectations, performance, and culture. Yet boards of directors traditionally played a limited role in overseeing healthcare quality, providing final approval of credentialing decisions but deferring to the medical staff to set standards for the institution. Case law and standards provide little guidance for board performance in overseeing quality of care.

The photo-fragmentation cross-section of 2,4,6-trinitrotoluene (TNT) vapor at room temperature was determined at different ultraviolet wavelengths (254, 300, 340, and 400 nm) by measuring the concentration of NO molecule with cavity ring down spectroscopy and correcting for the photo-fragmentation cross-section of NO(2). Nitric oxide (NO) molecules are produced by the TNT photo-fragmentation processes via an intermediate production of NO(2). Our results reveal that the photo-fragmentation cross-section of TNT changes appreciably with change in wavelength with xenon arc lamp illumination, increasing with decreasing excitation wavelength.
