To compare the performance of various CT reporting tools, including Zonal CT Visual Score (ZCVS), the number of involved lobes, and Radiological Society of North America (RSNA) categorization in predicting adverse outcomes among patients hospitalized due to lower respiratory symptoms during the COVID-19 pandemic. A total of 405 patients admitted with severe respiratory symptoms who underwent a chest CT were enrolled. The primary adverse outcome was ICU admission of patients. Predictive performances of reporting tools were compared using the area under the receiver operating characteristic curves (AUC ROC). Among the 405 patients, 39 (9.63%) required ICU support during their hospital stay. At least two or more observers reported a typical and indeterminate COVID-19 pneumonia CT pattern according to RSNA categorization in 70% (285/405) of patients. Among these, 63% (179/285) had a positive PCR test for the SARS-CoV-2 virus. The median number of lobes involved according to CT was higher in patients who required ICU support (median [IQR], 5[3; 5] vs. 3[0; 5]). The median ZCVS score was higher among the patients that subsequently required ICU support (median [IQR], 4[0; 12] vs. 13[5.75; 24]). The bootstrap comparisons of AUC ROC showed significant differences between reporting tools, and the ZCVS was found to be superior (AUC ROC, 71 to 75 %). The ZCVS score at the first admission showed a linear and significant association with adverse outcomes among patients with lower respiratory tract symptoms during the COVID-19 pandemic.Despite advances in the understanding of disease pathobiology, treatment for relapsed or refractory acute myeloid leukemia (R/R AML) remains challenging. The prognosis of R/R AML remains extremely poor despite chemotherapy and bone marrow transplants. Discoveries on recurrent and novel genetic mutations, such as FLT3-ITD and IDH1/IDH2, critical signaling pathways, and unique molecular markers expressed on the surface of leukemic cells have been under investigation for the management of R/R AML. Other than monoclonal antibodies, diabodies and triabodies are new targeted therapies developed in recent years and will be the new direction of immunotherapy. Targeted agents combined intensive regimens can be viable options for salvage therapy and as bridges to allogeneic transplant. Future directions will focus on novel, efficient and targeted combinations, low-toxicity maintenance, and individualized precision strategies. Here, we review the major recent advances of targeted therapies in the treatment of R/R AML.

To compare academic and mental health outcomes across diverse gender identities in the context of interpersonal violence and campus housing.

45,549 students from 124 self-selected post-secondary institutions.

Various academic and health measures from the National College Health Assessment Spring 2017 dataset were analyzed for differences across five gender identities (cis women, cis men, transwomen, transmen, and genderqueer students), and two housing categories (university housing and non-university housing).

When compared to cisgender peers, gender diverse students reported greater experiences of interpersonal violence and higher levels of negative academic and mental health outcomes. Living in university housing was associated with an increase in these disparities.

University housing, which usually reinforces fixed gender binaries, is associated with worse outcomes for gender diverse students. These data can help higher education institutions better understand and address problems that disproportionately impact transgender and gender diverse students, who represent a growing demographic.

Although he stated the idea occurred to him in 1805, his laboratory notes show he developed the first table of atomic weights in 1803. Historians over the years have provided conflicting narratives to explain the different dates. In this paper, I examine Dalton's activities as a creative individual and a practicing chemist, arguing that Dalton's concept of atomic size was not an "aha" moment occurring in 1805, but one that he used right from the start in 1803 to develop his chemical atomic theory. The concepts of atomic size and relative atomic weights emerged in 1803 from his investigations into caloric and the composition of nitric acid, respectively, not from his studies on gaseous solubility. In 1805, Dalton applied his 1803 concept of atomic size to explain a different problem, one of gaseous diffusion. Dalton's 1805 epiphany should join the stage with other great insights in the history of science, such as those of Archimedes, Kekulé, and Poincaré.As her second and third names suggest, Theresa Kopp Baumann (1856-1944) was the daughter and subsequently the wife of eminent German academic chemists. Her substantial unpublished autobiography, written ca. 1910 and presented here in English translation in an edited and considerably abridged form, provides unique insight from a privileged female perspective into the socio-cultural aspects of German academic science in its period of greatest international reputation and influence. In the two cases-in-point that are vividly recounted there - her life as daughter and then as wife - it also gives shape and colour to the many ways in which gendered domestic roles invisibly condition and assist scientific activity.

Graduate student mental health is a growing concern and the need for interventions is well-documented. This manuscript outlines an Acceptance and Commitment Therapy group treatment for graduate students intended to promote psychological flexibility through the cultivation of six processes contact with the present moment (mindfulness), freely chosen life direction (values), distance from thoughts (defusion), nonjudgmental acknowledgement of one's internal experiences (acceptance), meta-awareness of one's own experiences (self-as-context), and ongoing patterns of behavior in the service of values (committed action).

The treatment was delivered to graduate students across academic disciplines with variable psychological concerns over several semesters.

Graduate students completed measures of preliminary acceptability.

Clients perceived the intervention positively and believed they benefited from participating.

Treatment evaluation information support the social validity and acceptability of the treating. Conclusion Treatment evaluation information support the social validity and acceptability of the treatment and justify future studies assessing treatment efficacy and effectiveness.This study tested the hypothesis that early left ventricular (LV) relaxation is impaired in older obese patients with heart failure with preserved ejection fraction (HFpEF), and related to decreased peak exercise oxygen uptake (peak V̇o2). LV strain and strain rate were measured by feature tracking of magnetic resonance cine images in 79 older obese patients with HFpEF (mean age 66 yr; mean body mass index 38 kg/m2) and 54 healthy control participants. LV diastolic strain rates were indexed to cardiac preload as estimated by echocardiography derived diastolic filling pressures (E/e'), and correlated to peak V̇o2. LV circumferential early diastolic strain rate was impaired in HFpEF compared with controls (0.93 ± 0.05/s vs. 1.20 ± 0.07/s, P = 0.014); however, we observed no group differences in early LV radial or longitudinal diastolic strain rates. Isolating myocardial relaxation by indexing all three early LV diastolic strain rates (i.e. circumferential, radial, and longitudinal) to E/e' amplified the group dced peak V̇o2. In contrast, the data show a much stronger relationship between elevated LV filling pressures and exercise intolerance, refocusing future therapeutic priorities.The insulin-like growth factor 1 receptor (IGF1R) and phosphoinositide 3-kinase p110α (PI3K) are critical regulators of exercise-induced physiological cardiac hypertrophy and provide protection in experimental models of pathological remodeling and heart failure. Forkhead box class O1 (FoxO1) is a transcription factor that regulates cardiomyocyte hypertrophy downstream of IGF1R/PI3K activation in vitro, but its role in physiological hypertrophy in vivo was unknown. We generated cardiomyocyte-specific FoxO1 knockout (cKO) mice and assessed the phenotype under basal conditions and settings of physiological hypertrophy induced by 1) swim training or 2) cardiac-specific transgenic expression of constitutively active PI3K (caPI3KTg+). Under basal conditions, male and female cKO mice displayed mild interstitial fibrosis compared with control (CON) littermates, but no other signs of cardiac pathology were present. In response to exercise training, female CON mice displayed an increase (∼21%) in heart weight normalizef physiological hypertrophy has remained largely elusive. To our knowledge, this is the first study to show that the transcription factor FoxO1 is a critical mediator of exercise-induced cardiac hypertrophy. Given that exercise-induced hypertrophy is protective, this finding has important implications when one is considering FoxO1 as a target for treating the diseased heart.Use of electronic cigarettes is rapidly increasing among youth and young adults, but little is known regarding the long-term cardiopulmonary health impacts of these nicotine-containing devices. Our group has previously demonstrated that chronic, inhaled nicotine induces pulmonary hypertension (PH) and right ventricular (RV) remodeling in mice. These changes were associated with upregulated RV angiotensin-converting enzyme (ACE). Angiotensin II receptor blockers (ARBs) have been shown to reverse cigarette smoking-induced PH in rats. ACE inhibitor and ARB use in a large retrospective cohort of patients with PH is associated with improved survival. Here, we utilized losartan (an ARB specific for angiotensin II type 1 receptor) to further explore nicotine-induced PH. Male C57BL/6 mice received nicotine vapor for 12 h/day, and exposure was assessed using serum cotinine to achieve levels comparable to human smokers or electronic cigarette users. Simufilam research buy Mice were exposed to nicotine for 8 wk and a subset was treated with lension and right ventricular remodeling. This novel finding provides preclinical evidence for the use of renin-angiotensin system-based therapies in the treatment of pulmonary hypertension, particularly in patients with a history of tobacco-product use.MicroRNAs (miRNAs) are small regulatory molecules that are involved in posttranscriptional modifications. These noncoding RNAs are usually ferried by extracellular carriers such as exosomes or other protein and lipid carriers inside a range of body fluids including plasma and urine. Due to their ability to withstand harsh external conditions, exosomal miRNAs possess enormous potential as noninvasive disease biomarkers for, notably hypertension, whereby exosomal miRNAs have been implicated in its pathophysiological processes. More importantly, alterations in the microenvironment as a result of disease progression can induce active and selective loading of miRNAs into exosomes. In this paper, we first review the mechanisms of miRNA loading into exosomes, followed by the roles of exosomal miRNAs in the development of hypertension, and the potentials of exosomal miRNAs as biomarkers in comparison with other free circulating miRNAs. Finally, challenges and future research surrounding exosomal miRNAs will also be discussed.
