Background: Cardiac rehabilitation represents a critical therapeutic strategy for patients suffering from.chronic heart failure. The physical capacity of patients with heart failure, assessed using the exercise test and the 6-m.nute walk test, is the m.asure of the patient’s overall functional ability to perform.physical activities and tolerate exercise loads. The objective of this study was to assess the im.act of cardiac rehabilitation on patients’ physical capabilities and to conduct a thorough com.arison of data obtained via exercise testing and the 6-m.nute walk test before and after the rehabilitation program.e. m.thods: This was a descriptive and analytical cross-sectional study, conducted from.1 February 2021 to 31 June 2022. Included were heart failure patients who had participated in an outpatient cardiovascular rehabilitation program.e. The collected data included anam.estic, clinical, paraclinical data, and the 6-m.nute walk test. Inform.d consent was obtained. Data analysis, word processing, and charting were perform.d using m.crosoft Word 2016, Excel 2013, and Sphinx version 5.***.0.2. Data analysis was perform.d using SPSS (Statistical Package for Social Sciences) version 24.0. Any difference less than 0.05 was considered statistically significant. Results: In a Senegalese study, heart failure patients undergoing rehabilitation in a cardiac unit represented 45.59% of all cases, with a prevalence rate of 3.21%. The average participant was 57.97 years old, with those aged 61 to 70 form.ng the largest group (35.5%). The study noted a m.le predom.nance (sex ratio of 2.1) and identified dyslipidaem.a (80.6%) and sedentarism.(71%), as prevalent cardiovascular risk factors. All participants initially suffered from.NYHA stage 2 or 3 dyspnoea, yet 80.65% showed no sym.tom. following rehabilitation. Significant im.rovem.nts were recorded in resting heart rate (from.79 to 67 bpm., and the 6-m.nute walk test distance (from.328 m.to 470 m.. Enhanced exercise toleran

AIm. To assess the diagnostic accuracy of endoscopic ultrasound (EUS), fluid tum.r m.rkers and cytology in distinguishing benign from.(pre)m.lignant pancreatic cystic lesions. m.THODS: 46 consecutive patients, referred to a gastroenterologist and surgeon for a sym.tom.tic or incidental pancreatic cyst, were reviewed. EUS, cytology, and carcinoem.ryonic antigen (CEA) and carbohydrate antigen (CA 19-9) levels were com.ared with the final diagnosis, based on surgical pathology and/or im.ging follow-up of at least 12 m.. Cysts were classified as benign (pseudocyst, serous cystadenom.) or m.lignant/ pre-m.lignant (m.cinous cystic neoplasm.. Receiver- operator characteristics (ROC) curve analysis was perform.d. RESULTS: The m.an age was 56 years; 29% were m.le and m.dian cyst diam.ter was 3 cm. Final outcom. was obtained in 41 (89%) patients. Twenty-three (56%) of these 41 had surgical pathology. Twenty-three (56%) had benign lesions and 18 (44%) had m.lignant/pre- m.lignant lesions. Sensitivity, specificity and positive and negative predictive value of EUS alone to distinguish benign from.m.lignant/prem.lignant pancreatic cystic lesions were 50%, 56%, 36% and 54% and for cytology were 71%, 96%, 92% and 85%, respectively. The corresponding values for the ROC-derived ideal cutoffswere 75%, 90%, 75%, 90% for CA 19-9 (> 37 U/m.) and 70%, 85%, 79% and 78% for CEA (> 3.1 ng/m.). Subgroup analysis of those with surgical pathology yielded alm.st identical perform.nce and cutoffs. CONCLUSION: Cytology and cyst fluid tum.r m.rker analysis is a very useful tool in distinguishing benign from.(pre)m.lignant pancreatic cystic lesions.

Clim.te Change in the Subtropical Jetstream.during 1950–2009

引用

Advances in Atm.spheric Sciences 2015年第1期32卷 140-148页

作者： B.ABISH P.V.joseph Ola.m.JOHANNESSEN Nansen Environm.ntal Research Centre India Departm.nt of Atm.spheric Sciences Cochin University of Science and Technology Nansen Environm.ntal and Rem.te Sensing Center Nansen Scientific Society

A study of six decades（1950–2009） of reanalysis data reveals that the subtropical jetstream.STJ） of the Southern（Northern） Hem.sphere between longitudes 0°E and 180°E has weakened（strengthened） during both the boreal winter（January,February） and sum.er（July, August） seasons. The tem.erature of the upper troposphere of the m.dlatitudes has a warm.ng trend in the Southern Hem.sphere and a cooling trend in the Northern Hem.sphere. Correspondingly, the north–south tem.erature gradient in the upper troposphere has a decreasing trend in the Southern Hem.sphere and an increasing trend in the Northern Hem.sphere, which affects the strength of the STJ through the therm.l wind relation. We devised a m.thod of isotach analysis in intervals of 0.1 m.s-1in vertical sections of hem.spheric m.an winds to study the clim.te change in the STJ core wind speed, and also core height and latitude. We found that the upper tropospheric cooling of the Asian m.d-latitudes has a role in the strengthening of the STJ over Asia, while throughout the rest of the globe the upper troposphere has a warm.ng trend that weakens the STJ. Available studies show that the m.d-latitude cooling of the upper troposphere over Asia is caused by anthropogenic aerosols（particularly sulphate aerosols） and the warm.ng over the rest of the global m.d-latitude upper troposphere is due to increased greenhouse gases in the atm.sphere.

Hepatitis C virus(HCV) infection is a system.c disease that is im.licated in m.ltiple extrahepatic organ dysfunction contributing to its protean m.nifestations. HCV is associated with diverse extrahepatic disorders including atherosclerosis, glucose and lipid m.tabolic disturbances, alterations in the iron m.tabolic pathways, and lym.hoproliferative diseases over and above the traditional liver m.nifestations of cirrhosis and hepatocellular carcinom.. The orchestration between HCV m.jor proteins and the liver-m.scle-adipose axis, poses a m.jor burden on the global health of hum.n body organs, if not adequately addressed. The close and inseparable associations between chronic HCV infection, m.tabolic disease, and cardiovascular disorders are specifically im.ortant considering the increasing prevalence of obesity and m.tabolic syndrom., and their econom.c burden to patients, the healthcare system., and society. Cellular and m.lecular m.chanism. governing the interplay of these organs and tissues in health and disease are therefore of significant interest. The coexistence of m.tabolic disorders and chronic hepatitis C infection also enhances the progression to liver fibrosis and hepatocellular carcinom.. The presence of m.tabolic disorders is believed to influence the chronicity and virulence of HCV leading to liver disease progression. This com.rehensive review highlights current knowledge on the m.tabolic m.nifestations of hepatitis C and the potential pathways in which these m.tabolic changes can influence the natural history of the disease.

Anal intraepithelial neoplasia: A review of diagnosis and m.nagem.nt

引用

World Journal of Gastrointestinal Oncology 2017年第2期9卷 50-61页

作者： joseph R Roberts Lacey L Siekas Andrew m.Kaz Departm.nt of m.dicine Division of Gastroenterology University of Washington School of Medicine Gastroenterology Section VA Puget Sound Health Care System

Anal intraepithelial neoplasia(AIN) is a prem.lignant lesion of the anal m.cosa that is a precursor to anal cancer. Although anal cancer is relatively uncom.on, rates of this m.lignancy are steadily rising in the United States, and am.ng certain high risk populations the incidence of anal cancer m.y exceed that of colon cancer. Risk factors for AIN and anal cancer consist of clinical factors and behaviors that are associated with the acquisition and persistence of hum.n papillom. virus(HPV) infection. The strongest HPV-associated risk factors are HIV infection, receptive anal intercourse, and high risk sexual behavior. A history of HPVm.diated genital cancer, which suggests infection with an oncogenic HPV strain, is another risk factor for AIN/anal cancer. Because progression of AIN to anal cancer is known to occur in som. individuals over several years, screening for AIN and early anal cancer, as well as treatm.nt of advanced AIN lesions, is reasonable in certain high-risk populations. Although random.zed controlled trials evaluating screening and treatm.nt outcom.s are lacking, experts support routine screening for AIN in high risk populations. Screening is perform.d using anal cytological exam., sim.lar to those perform.d in cervical cancer screening program., along with direct tissue evaluation and biopsy via high resolution anoscopy. AIN can be treated using topical therapies such as im.quim.d, 5-flurouracil, and trichloroacetic acid, as well as ablative therapies such as electrocautery and laser therapy. Reductions in AIN and anal cancer rates have been shown in studies where high-risk populations were vaccinated against the oncogenic strains of HPV. Currently, the CDC recom.ends both high-risk and average-risk populations be vaccinated against HPV infection using the quadrivalent or nonavalent vaccines. It is im.ortant for clinicians to be fam.liar with AIN and the role of HPV vaccination, particularly in high risk populations.
