Cardiac Rehabilitation in the United States

Coronary heart disease (CHD) is a significant cause of morbidity and mortality in the United States (US). In addition to this, many of the risk factors of CHD, such as obesity, sedentary lifestyle, diabetes mellitus, and poor nutrition, are disproportionately high in the US. Despite the many known benefits of cardiac rehabilitation (CR), referral and participation rates in these programs are paradoxically low. Over the course of this review, we will discuss some of the many benefits of CR, some of the risk factors for CHD in the US, and factors that affect referral and participation in these programs.     

Health behaviors and cancer screening practices in long-term survivors of hematopoietic cell transplantation (HCT): a report from the BMT Survivor Study

Patients undergoing hematopoietic cell transplantation (HCT) are at increased risk of chronic health conditions, including second malignant neoplasms and cardiovascular disease. Little is known about health behaviors and cancer screening practices among HCT survivors that could moderate the risk of these conditions. The BM transplant survivor study examined health behaviors and cancer screening practices in individuals who underwent HCT between 1976 and 1998, and survived 2+ years. Health behavior was deemed as high risk, if an individual was a current smoker and if they reported risky alcohol intake (≥4 drinks per day (males), ≥3 drinks per day (females)) on days of alcohol consumption. Cancer screening assessment was per American Cancer Society recommendations. There were 1040 survivors: 42.7% underwent allogeneic HCT; 43.8% were female; median time from HCT: 7.4 years (range 2.0-27.7 years). Median age at study participation: 43.8 years (range 18.3-73.0 years). Multivariate regression analysis revealed younger age (<35 years) at study participation (Odds ratio (OR)=4.7; P<0.01) and lower education (相似文献   

TDP-43 in familial and sporadic frontotemporal lobar degeneration with ubiquitin inclusions

TAR DNA-binding protein 43 (TDP-43) is a major pathological protein of sporadic and familial frontotemporal lobar degeneration with ubiquitin-positive, tau-negative inclusions (FTLD-U) with or without motor neuron disease (MND). Thus, TDP-43 defines a novel class of neurodegenerative diseases called TDP-43 proteinopathies. We performed ubiquitin and TDP-43 immunohistochemistry on 193 cases of familial and sporadic FTLD with or without MND. On selected cases, immunoelectron microscopy and biochemistry were performed. Clinically defined frontotemporal dementias (FTDs) included four groups: 1) familial FTD with mutations in progranulin (n = 36), valosin-containing protein (n = 5), charged multivesicular body protein 2B (n = 4), and linked to chromosome 9p (n = 7); 2) familial cases of FTD with unknown gene association (n = 29); 3) sporadic FTD (n = 72); and 4) familial and sporadic FTD with MND (n = 40). Our studies confirm that the spectrum of TDP-43 proteinopathies includes most cases of sporadic and familial FTLD-U with and without MND and expand this disease spectrum to include reported families with FTD linked to chromosome 9p but not FTD with charged multivesicular body protein 2B mutations. Thus, despite significant clinical, genetic, and neuropathological heterogeneity of FTLD-U, TDP-43 is a common pathological substrate underlying a large subset of these disorders, thereby implicating TDP-43 in novel and unifying mechanisms of FTLD pathogenesis.
