Recent data have shown that single-fraction irradiation delivered to the whole brain in less than tenths of a second using FLASH radiotherapy (FLASH-RT), does not elicit neurocognitive deficits in mice. This observation has important clinical implications for the management of invasive and treatment-resistant brain tumors that involves relatively large irradiation volumes with high cytotoxic doses.

Therefore, we aimed at simultaneously investigating the antitumor efficacy and neuroprotective benefits of FLASH-RT 1-month after exposure, using a well-characterized murine orthotopic glioblastoma model. As fractionated regimens of radiotherapy are the standard of care for glioblastoma treatment, we incorporated dose fractionation to simultaneously validate the neuroprotective effects and optimized tumor treatments with FLASH-RT.

The capability of FLASH-RT to minimize the induction of radiation-induced brain toxicities has been attributed to the reduction of reactive oxygen species, casting some concern thatUveal melanoma is a rare cancer in adults, but its treatment is one of the clinical unmet needs in the melanoma field. Metastatic disease develops in approximately 50% of patients and is associated with poor survival due to the lack of effective treatment options. It provides a paradigm for cancers that show evidence of aberrant G protein-coupled receptor signaling, tumor dormancy, and liver-selective metastatic tropism and are associated with the loss of the BAP1 tumor suppressor. At the Melanoma Research Foundation CURE OM Science Meeting at the Society for Melanoma Research Meeting held in Utah on November 20, 2019, clinicians and researchers presented findings from their studies according to three themes within uveal melanoma (i) ongoing clinical trials, (ii) molecular determinants, and (iii) novel targets that could be translated into clinical trials. This meeting underscored the high interest in the uveal melanoma research field and the unmet need for effective treatment strategies for late-stage disease. Findings from ongoing clinical trials are promising, and multiple studies show how novel combinatorial strategies increase response rates. Novel targets and tumor vulnerabilities identified bioinformatically or through high-throughput screens also reveal new opportunities to target uveal melanoma. The future directions pursued by the uveal melanoma research field will likely have an impact on other cancer types that harbor similar genetic alterations and/or show similar biological properties.Regulation of gene expression is essential for the functioning of all eukaryotic organisms. HDAC inhibitor Understanding gene expression regulation requires determining which proteins interact with regulatory elements in chromatin. Mass spectrometry-based analysis of chromatin has emerged as a powerful tool to identify proteins associated with gene regulation, as it allows studying protein function and protein complex formation in their in vivo chromatin-bound context. Total chromatin isolated from cells can be directly analysed using mass spectrometry or further fractionated into transcriptionally active and inactive chromatin prior to MS-based analysis. Newly formed chromatin that is assembled during DNA replication can also be specifically isolated and analysed. Furthermore, capturing specific chromatin domains facilitates the identification of previously unknown transcription factors interacting with these domains. Finally, in recent years, advances have been made towards identifying proteins that interact with a single genomic locus of interest. In this review, we highlight the power of chromatin proteomics approaches and how these provide complementary alternatives compared to conventional affinity purification methods. Furthermore, we discuss the biochemical challenges that should be addressed to consolidate and expand the role of chromatin proteomics as a key technology in the context of gene expression regulation and epigenetics research in health and disease.
This short study was performed to better understand the time frame associated with changes in SARS-CoV-2 nucleic acid testing and provide recommendations for repeat testing. Recommendations are useful as little guidance is available for repeat testing in patients being followed expectantly for changes in disease.

A review of laboratory data of tests for SARS-CoV-2 nucleic acid was performed selecting patients who had changing results. Time between changes in test results was determined to provide guidance for repeat testing.

The Interquartile Range (IQR) of data for patients who had a negative to positive change in laboratory testing (progression) was 6-16 days (median=9 days). The IQR of data for patients who had a positive to negative change in test results (remission) was 9-21 days (median=14 days).

Because sampling of the nares or nasopharynx can be variable, repeat testing should be performed swiftly when symptomatic patients are negative. The data in this short study vary widely, so authors recommend repeat testing during a period of time associated with the IQR or median (see results above).

To explore the expression of secretagogin (SCGN) in neuroendocrine carcinoma of the uterine cervix and analyse its relationship with clinicopathological characteristics and prognosis.

From January 2010 to December 2017, 44 patients with cervical neuroendocrine carcinoma undergoing surgery were included in the study group, and 55 patients with cervical non-neuroendocrine carcinoma (including 30 cases of cervical squamous cell carcinoma and 25 cases of cervical adenocarcinoma) undergoing surgery were included in the control group. Immunohistochemical staining of SCGN was performed in both groups and compared with three common neuroendocrine markers, chromogranin A, synaptophysin (Syn) and CD56 in the study group. Detailed clinicopathological data of the two groups were analysed, and the patient survival in the study group was followed up.

The positive expression of SCGN in cervical neuroendocrine carcinoma, cervical adenocarcinoma and squamous cell carcinoma was 65.9% (29/44), 8% (2/25) and 0%, respectively. The positive expression of SCGN in cervical neuroendocrine carcinoma was significantly higher than that in cervical adenocarcinoma and squamous cell carcinoma (χ
=44.5, p<0.001). There were no statistical differences among the positive expression of SCGN and three common neuroendocrine markers (p>0.05 for all). The intensity of SCGN staining in patients with cervical neuroendocrine carcinoma with lymph node metastasis was significantly higher than that in patients without lymph node metastasis (p=0.020). link2 However, there was no significant association between SCGN expression and survival among patients with cervical neuroendocrine carcinoma (p=0.633).

SCGN is a new neuroendocrine marker for cervical neuroendocrine carcinoma, whose expression correlates with lymph node metastasis.

This type of myocardial infarction is commonly seen in hospitalized patients. Since the introduction of clear definition, diagnostic criteria and International Classification of Disease (ICD) codes, the diagnosis has become increasingly common. There still remains plenty to learn about MI type 2 especially prevention and treatment strategies. Studies have shown that there is increased mortality and morbidity associated with MI type 2 when compared to MI type 1, and there may be benefit in having a multi-disciplinary approach including cardiology when treating such patients. Secondary prevention therapies may also play a role in decreasing adverse events from MI type 2. However, randomized control trials are insufficient, and results of studies are cautiously interpreted. In this article we have assessed the current evidence on MI type 2 and the gap in literature that will potentially be the focus of future analyses.Introduction Infants of mothers with substance use disorder (SUD) are exposed to complex social environments and increased childhood health risks that can lead to adverse consequences throughout the lifespan. GunderKids, a voluntary, specialized, comprehensive pediatric care management program, was developed to mitigate many of these adverse consequences. link3 Our organization is evaluating several clinical outcomes related to health and development in children born to women with SUD. The current study addressed the timeliness of vaccination coverage among these infants.Methods This descriptive comparative preliminary study evaluated data of infants and their mothers with SUD who were previously identified during prenatal care visits either by self-report or by positive urine screens. Sociodemographic and vaccination data were extracted from a longitudinal master dataset of variables developed and maintained through retrospective review of electronic health records (EHRs) of these mothers and their infants. Timelilike GunderKids may assist in mitigating adverse health consequences and timeliness of vaccination coverage might be used as a proxy for measuring program effectiveness. Further investigation is recommended to determine clinical, individual, and organizational factors that influence parental behaviors and pediatric outcomes within SUD-exposed families.Background Transcatheter aortic valve replacement (TAVR) is a rapidly evolving treatment for severe aortic stenosis. However, uncertainties exist for optimal valve selection as there are few long-term studies comparing patient survival by valve type.Objective We hypothesized that self-expandable valves (SEV) would provide a survival advantage over balloon expandable valves (BEV), as SEV continue to expand and might better accommodate to the anatomy of the aortic valve over time.Methods We examined outcomes according to valve type from a rural tertiary referral center between 2012 and 2017.Results Out of 269 patients, 77 deaths (28.6%) occurred over the study period with 6 deaths by 1 month post-TAVR and 37 deaths by 1 year post-TAVR. The median observation time for survivors was 21.5 months. The probability of survival at 3 years was 60.7% and 61.9% for patients who underwent treatment with SEV and BEV, respectively. There was no statistically significant difference in overall patient survival with or without adjustment for factors such as age, sex, race, and aortic valve area. Additionally, in a secondary analysis restricted to those patients treated in later years (2015-2017) survival among patients with BEV appeared superior (HR=0.456, P=0.015).Conclusion Patients who underwent TAVR at a rural medical center with SEV showed similar survival compared to those who received a BEV. Superior survival was observed among those who received BEV versus SEV between 2015 and 2017.
