Our purpose was to analyze the pattern of failure in glioblastoma (GBM) patients at first recurrence after radiotherapy and temozolomide and its relationship with different factors. From 77 consecutive GBM patients treated at our institution with fluorescence guided surgery and standard radiochemotherapy, 58 first recurrences were identified and included in a retrospective review. Clinical data including age, Karnofsky performance score, preoperative tumor volume and location, extend of resection, MGMT promoter methylation status, time to progression (PFS), overall survival (OS) and adjuvant t

Primary biliary cholangitis is an autoimmune cholestatic liver disease characterized by progressive destruction of bile ducts, which can ultimately progress to chronic liver disease and cirrhosis. Ursodeoxycholic acid and obeticholic acid are the only 2 Food and Drug Administration (FDA)-approved medications for primary biliary cholangitis. Unfortunately, up to 40% of patients with primary biliary cholangitis have an incomplete response to ursodeoxycholic acid, warranting an essential need for additional therapeutics. Peroxisome proliferator-activated receptor agonists have shown promising dat

Untargeted metabolomic studies have identified potential biomarkers of colorectal cancer risk, but evidence is still limited and broadly inconsistent. Among 39,239 Cancer Prevention Study II Nutrition cohort participants who provided a blood sample between 1998–2001, 517 newly diagnosed colorectal cancers were identified through 30 June 2015. In this nested case–control study, controls were matched 1:1 to cases on age, sex, race and date of blood draw. Mass spectroscopy-based metabolomic analyses of pre-diagnostic plasma identified 886 named metabolites, after quality control exclusions. Condi

Transcranial alternating-current stimulation (tACS) for entraining alpha activity holds potential for influencing mental function, both in laboratory and clinical settings. While initial results of alpha entrainment are promising, questions remain regarding its translational potential-namely if tACS alpha entrainment is sufficiently robust to context and to what extent it can be upscaled to multi-electrode arrangements needed to direct currents into precise brain loci. We set out to explore these questions by administering alternating current through a multi-electrode montage (mtACS), while va

BACKGROUND: Displaced transverse fractures of the body of the patella are usually associated with disruption of extensor mechanism and should be fixed surgically. The most common method is a tension band wiring (TBW) technique. Some surgeons concurrently employ an augmented circumferential cerclage wiring (ACCW) technique to help fracture stabilization and aid in fracture healing; however, its role and effect on the treatment outcomes is unclear. METHODS: We performed a STROBE-compliant retrospective observational cohort study on all cases of acute closed patella fracture that were treated at

Abstract Background Despite more than 50 years of research, no robust evidence suggests that inoculation of cereals and other non-legumes with free-living and/or endophytic bacteria leads to fixation of agronomically significant quantities of dinitrogen gas (N 2 ) from the atmosphere. A plethora of new products claims to increase the growth and yields of major cereals and other crops through stimulating N 2 -fixation by inoculating with bacteria. Scope We review the literature on N 2 -fixation by bacteria in the rhizosphere and as endophytes in non-legume plants. We find no unequivocal evidenc

As a technique that can compactly represent complex patterns, machine learning has significant potential for predictive inference in multi-source and heterogeneous information fusion scenarios. K-fold cross-validation (CV) is the most common approach for ascertaining the likelihood that a machine learning outcome is generated by chance and frequently outperforms conventional hypothesis testing. This improvement arises from measures directly obtained from machine learning classifications, such as accuracy, that do not have a parametric description.

AI decision support systems can assist clinicians in planning adaptive treatment strategies that can dynamically react to individuals' cancer progression for effective personalized care. However, AI's imperfections can lead to suboptimal therapeutics if clinicians over or under rely on AI. To investigate such collaborative decision-making process, we conducted a Human-AI interaction study on response-adaptive radiotherapy for non-small cell lung cancer and hepatocellular carcinoma. We investigated two levels of collaborative behavior: model-agnostic and model-specific; and found that Human-AI

Emerging evidence suggests that Omega-3 polyunsaturated fatty acids (PUFAs) are essential structural and functional nutrients that significantly influence the composition and function of the gut microbiota, a key mediator of host health. Although evidence suggests that increasing tissue Omega-3 levels through dietary intervention may optimize gut microbiota-host interaction through modulation of composition, metabolite production, and the intestinal mucus barrier, some studies have reported inconsistent findings regarding these protective effects.

Mumps virus (MuV) infection has high tropism to the testis and usually leads to orchitis, an etiological factor in male infertility. However, MuV replication in testicular cells and the cellular antiviral responses against MuV are not fully understood. The present study showed that MuV infected the majority of testicular cells, including Leydig cells (LC), testicular macrophages, Sertoli cells (SC), and male germ cells (GC). MuV was replicated at relatively high efficiencies in SC compared with LC and testicular macrophages. In contrast, MuV did not replicate in male GC. Notably, testicular ce
