Aneuploidy, the gain or loss of chromosomes in a cell, is a hallmark of cancer. Although our understanding of the contribution of aneuploidy to cancer initiation and progression is incomplete, significant progress has been made in uncovering the cellular consequences of aneuploidy and how aneuploid cancer cells self-adapt to promote tumorigenesis. Aneuploidy is physiologically associated with significant cellular stress but, paradoxically, it favors tumor progression. Although more common in solid tumors, different forms of aneuploidy represent the initiating oncogenic lesion in patients with B cell acute lymphoblastic leukemia (B-ALL), making B-ALL an excellent model for studying the role of aneuploidy in tumorigenesis. We review the molecular mechanisms underlying aneuploidy and discuss its contributions to B-ALL initiation and progression.Coronavirus disease 2019 (COVID-19) has become a rapid worldwide pandemic. While COVID-19 primarily manifests as an interstitial pneumonia and severe acute respiratory distress syndrome, severe involvement of other organs has been documented. In this article, we will review the role of non-contrast chest computed tomography in the diagnosis, follow-up and prognosis of patients affected by COVID-19 pneumonia with a detailed description of the imaging findings that may be encountered. Given that patients with COVID-19 may also suffer from coagulopathy, we will discuss the role of CT pulmonary angiography in the detection of acute pulmonary embolism. Finally, we will describe more advanced applications of CT in the differential diagnosis of myocardial injury with an emphasis on ruling out acute coronary syndrome and myocarditis.
We aim to evaluate serum vitamin D levels, vitamin D receptor (VDR) expression in the intestinal epithelium, and their relation with epithelial barrier proteins and bone metabolism in children with Celiac disease (CD).
Immunostaining for VDR, Claudin-2 and E-cadherin was performed in duodenal samples of the patients with CD and controls. H-score [∑Pi(I+1)] where I is the intensity score and Pi is the corresponding percentage of stained cells was calculated for each samples. The clinic, laboratory and histopathological findings were compared between patients and controls.
Thirty-six patients with CD and age and sex matched 36 controls were enrolled. 25-OH vitamin D levels were significantly lower in the patient group compared to the control group. The mean bone mineral density (BMD) value was significantly lower in patients with vitamin D deficiency compared to patients with normal vitamin D level. H-scores for both VDR and Claudin-2 were significantly lower in patient group when compared to the control s Claudin-2 and E-cadherin which have important roles in paracellular pathway, was decreased in children with CD in correlation with histological findings of disease severity. Furthermore, deficiency of vitamin D was related to decreased expression of VDR and epithelial barrier proteins E-cadherin and Claudin-2. These findings indicate that paracellular pathway structures responsible for calcium absorption are disturbed in CD which is aggravated by vitamin D deficiency.
This is a longitudinal, observational, multicenter, cohort study.
Thumb carpometacarpal (CMC) osteoarthritis (OA) is associated with more pain and restrictions than other hand OA. The use of patient-identified occupational performance goals to guide hand therapy treatment and to measure clinical outcomes is fundamental for a patient-centered intervention. The COPM enables subjects to identify goals for hand therapy and engage in a subject-specific therapeutic process.
The purpose of this study is to evaluate the convergent validity and responsiveness of the COPM to evaluate the relationship between the patient's self-perception and satisfaction of performance in everyday living and pain intensity, upper limb function, and manual ability.
Eligible participants to multiple hand therapy centers were recruited. Outcomes measures (VAS scale, QuickDASH, MAM-36, and the COPM questionnaire) were measured at the baseline and 3 months after.
One hundred forty-five (n = 145) consecutive patients for five diffend, in comparison with others upper limb scales, does not require the use of another complementary scale for addressing both satisfaction and ADL status. Tacrolimus cell line COPM is an instrument with a good convergent validity and responsiveness to evaluate the relationship between the patient's self-perception and satisfaction in thumb CMC OA.Metabolic syndrome (MS) is associated with a sedentary and stressful lifestyle and affects underactive people disproportionately. Yoga is considered to be a low-impact mind-body stress-relieving exercise, and researchers are increasing their focus on the benefits of yoga for managing metabolic disorders. It is also important for physicians and health care professionals to understand the therapeutic efficacy of yoga intervention, in terms of its type, duration and frequency on various MS risk factors. The present review summarizes the current scientific understanding of the effects of yoga on MS risk factors such as glucose homeostasis markers, lipid profile, adipocytokines and cardiovascular risk factors, and discusses the possible mechanisms of action. MEDLINE, PubMed, Scopus and Cochrane Library were searched from their inception up to December 2019, using the keywords "metabolic syndrome," "diabetes," "cardiovascular diseases," "obesity" and "yoga." The literature summarized in this review have shown mixed effects of yoga on MS risk factors and do not provide robust evidence for its efficacy. More rigorous research and well-designed trials that have a higher standard of methodology and evaluate yoga's long-term impacts on MS are needed. Understanding yoga's biochemical and molecular mechanisms of action on various metabolic pathways is also needed.
Health care providers are unprepared to meet the health needs of patients who have disabilities. Disability training is needed, yet there is little agreement about what should be taught.
Establish a national consensus on what healthcare providers across disciplines need to know to provide quality care to patients with all types of disabilities (e.g., mobility, sensory, developmental, mental health).
People with disabilities, disability advocates, family members of people with disabilities, disability and health professionals, and inter-disciplinary health educators systematically evaluated and provided feedback on a draft set of disability competencies. Based on this feedback, competencies were iteratively refined.
After two waves of feedback, six competencies, 49 sub-competencies, and 10 principles and values emerged that addressed topics such as respect, person-centered care, and awareness of physical, attitudinal, and communication health care barriers. An overwhelming majority (89%) agreed or strongly agreed that the disability competencies reflected the core understandings needed to provide quality care for patients with disabilities, were relevant across disability types (85%), and across health care disciplines (96%).
