| 1 | Diabetes and cardiovascular disease: Epidemiology, biological mechanisms, treatment recommendations and future research显示文摘The incidence of diabetes mellitus(DM) continues to rise and has quickly become one of the most prevalent and costly chronic diseases worldwide. A close link exists between DM and cardiovascular disease(CVD), which is the most prevalent cause of morbidity and mortality in diabetic patients. Cardiovascular(CV) risk factors such as obesity, hypertension and dyslipidemia are common in patients with DM, placing them at increased risk for cardiac events. In addition, many studies have found biological mechanisms associated with DM that independently increase the risk of CVD in diabetic patients. Therefore, targeting CV risk factors in patients with DM is critical to minimize the long-term CV complications of the disease. This paper summarizes the relationship between diabetes and CVD, examines possible mechanisms of disease progression, discusses current treatment recommendations, and outlines future research directions. | Benjamin M Leon Thomas M Maddox | 2015 | World Journal of Diabetes2015，6，13： | 39 |
| 2 | 2018加拿大心境障碍与焦虑障碍治疗协作组/国际双相障碍学会指南:双相障碍的管理显示文摘加拿大心境障碍与焦虑障碍治疗协作组(Canadian Network for Mood and Anxiety Treatments,CANMAT)曾于2005年发布了第1版双相障碍管理指南,并分别于2007、2009和2013年对该指南进行了更新,其中最近的2次更新是与国际双相障碍学会(International Society for Bipolar Disorders,ISBD)合作完成。2018版CANMAT/ISBD双相障碍治疗指南(以下简称指南)反映了自2005年首版指南发表以来本领域取得的重大进展,包括疾病诊断与疾病管理的更新以及药物治疗与心理治疗的近期研究进展。这些前沿进展中综合考虑了循证证据的级别,并基于治疗疗效、临床实践经验、安全性、耐受性和药物导致的转相风险等,对一线、二线及三线治疗方案进行了简明而清晰的推荐。本指南中新增内容涵盖了双相Ⅰ型障碍(BD-Ⅰ)的躁狂发作急性期、抑郁发作急性期和双相障碍维持期的一线及二线治疗推荐等级划分。这种对治疗推荐等级的划分综合考虑了治疗方法对双相障碍不同时相的影响,将进一步帮助临床医生做出基于循证证据的治疗决策。锂盐、喹硫平、双丙戊酸盐、阿塞那平、阿立哌唑、帕利哌酮、利培酮和卡利拉嗪单药或联合使用被推荐为躁狂发作急性期的一线治疗选择。BD-Ⅰ抑郁期的一线治疗选择包括喹硫平、鲁拉西酮、锂盐、拉莫三嗪单药,鲁拉西酮联合锂盐或双丙戊酸盐或拉莫三嗪辅助治疗。尽管急性期治疗有效的药物通常应继续用于BD-Ⅰ的维持期治疗,但也存在一些特殊情况(例如抗抑郁药)。现有数据表明,锂盐、喹硫平、双丙戊酸盐、拉莫三嗪、阿塞那平和阿立哌唑单药或联合治疗应被视为维持治疗的初始或更换治疗方案时的一线选择。除了探讨BD-Ⅰ的相关问题外,本指南中还对双相Ⅱ型障碍(BD-Ⅱ)的临床管理进行了系统回顾并给予治疗推荐,同时针对特殊人群也有相关推荐,如处于各个生殖周期的女性、儿童、青少年和老年人。此外,本指南中还讨论了特定精神疾病及共病(如物质滥用、焦虑障碍和代谢性疾病)的影响。最后,本指南中概述了安全性和药物监测的相关问题。CANMAT/ISBD工作组希望本指南能够成为全球临床医生的实用工具。 | Lakshmi N Yatham Sidney H Kennedy Sagar V Parikh Ayal Sehaffer David J Bond Benicio N Frey Verinder Sharma Benjamin I Goldstein Soham Rej Serge Beaulieu Martin Alda Glenda MaeQueen Roumen V Milev Arun Ravindran Claire O'Donovan Diane Mclntosh Raymond W Lam Gustavo Vazquez Flavio Kapczinski Roger S Melntyre Jan Kozicky Shigenobu Kanba Beny Lafer Trisha Suppes Joseph R Calabrese Eduard Vieta Gin Malhi Robert M Post Michael Berk 胡晨(译) 王刚(译) | 2019 | 中华精神科杂志2019，52，1： | 25 |
| 3 | Treatment of functional dyspepsia with sertraline:A double-blind randomized placebo-controlled pilot study显示文摘AIM:To evaluate sertraline,a selective serotonin reuptake inhibitor in the treatment of patients with functional dyspepsia.METHODS:Consecutive tertiary hospital patients with a clinical diagnosis of functional dyspepsia(FD) according to the Rome Ⅱ criteria with a Hong Kong dyspepsia index(HKDI) of greater than 16 were recruited.Patients commenced enrolment prior to the inception of the Rome Ⅲ criteria for functional dyspepsia.All patients were ethnic Chinese,had a normal upper endoscopy and were Helicobacter pylori negative prior to enrolment.Study patients were randomized to receive sertraline 50 mg or placebo daily for 8 wk.HKDI symptom scores,quality of life,hospital anxiety and depression(HAD) scale and global symptom relief were evaluated before,during and after treatment.Adverse effects were monitored during and after treatment.RESULTS:A total of 193 patients were randomized in the intention to treat(ITT),and 150 patients were included in the per protocol(PP) analysis.In both the ITT and PP,there was no difference in the primary outcome of global dyspepsia symptoms between the sertraline and placebo groups at week 8.In the ITT analysis,98 and 95 patients were randomized to the sertraline and placebo groups respectively.A total of 43 patients withdrew from the study(22.3%) by week 8,with 23 of the 24 drop-outs in the sertraline group occurring prior to week 4(95.8%).In contrast,in the placebo arm,11 of 19 patients dropped out by week 4(57.9%).Utilizing the last response carried forward to account for the drop-outs,there were no differences between the sertraline and placebo groups at baseline in terms of the HKDI,HKDI 26.08 ± 6.19 vs 26.70 ± 5.89,P = 0.433;and at week 8,HKDI 22.41 ± 6.36 vs 23.25 ± 7.30,P = 0.352 respectively.In the PP analysis,74 and 76 patients were randomized to the sertraline and placebo groups respectively.At baseline,there were no statistically significant differences between the sertraline and placebo groups,HKDI 25.83 ± 6.313 vs 27.19 ± 5.929 respectively,P = 0.233;however by week 8,patients in the sertraline group demonstrated a statistically significant difference in their Hong Kong Dyspepsia Index compared to placebo,HKDI 20.53 ± 6.917 vs 23.34 ± 7.199,P = 0.02,respectively).There was also no statistically significant difference in overall quality of life measures or the HAD scale related to treatment in either the ITT or PP analysis at week 8.CONCLUSION:This pilot study,the first to examine sertraline,a selective serotonin reuptake inhibitor,for the management of FD,did not find that it was superior to placebo. | Victoria PY Tan Tin K Cheung Wai M Wong Roberta Pang Benjamin CY Wong | 2012 | World Journal of Gastroenterology2012，18，42： | 14 |
| 4 | T1ρ/T2 mapping and histopathology of degenerative cartilage in advanced knee osteoarthritis显示文摘AIM To investigate whether normal thickness cartilage in osteoarthritic knees demonstrate depletion of proteoglycan or collagen content compared to healthy knees.METHODS Magnetic resonance(MR) images were acquired from5 subjects scheduled for total knee arthroplasty(TKA)(mean age 70 years) and 20 young healthy control subjects without knee pain(mean age 28.9 years). MR images of T1ρ mapping, T2 mapping, and fat suppressed proton-density weighted sequences were obtained.Following TKA each condyle was divided into 4 parts(distal medial, posterior medial, distal lateral, posterior lateral) for cartilage analysis. Twenty specimens(bone and cartilage blocks) were examined. For each joint,the degree and extent of cartilage destruction was determined using the Osteoarthritis Research Society International cartilage histopathology assessment system.In magnetic resonance imaging(MRI) analysis, 2 readers performed cartilage segmentation for T1ρ/T2 values and cartilage thickness measurement.RESULTS Eleven areas in MRI including normal or near normal cartilage thickness were selected. The corresponding histopathological sections demonstrated mild to moderate osteoarthritis(OA). There was no significant difference in cartilage thickness in MRI between control and advanced OA samples [medial distal condyle, P = 0.461;medial posterior condyle(MPC), P = 0.352; lateral distal condyle, P = 0.654; lateral posterior condyle, P = 0.550],suggesting arthritic specimens were morphologically similar to normal or early staged degenerative cartilage.Cartilage T2 and T1ρ values from the MPC were significantly higher among the patients with advanced OA(P= 0.043). For remaining condylar samples there was no statistical difference in T2 and T1ρ values between cases and controls but there was a trend towards higher values in advanced OA patients. CONCLUSION Though cartilage is morphologically normal or near normal, degenerative changes exist in advanced OA patients. These changes can be detected with T2 and T1ρ MRI techniques. | Benjamin S Kester Philip M Carpenter Hon J Yu Taiki Nozaki Yasuhito Kaneko Hiroshi Yoshioka Ran Schwarzkopf | 2017 | World Journal of Orthopedics2017，8，4： | 12 |

| 6 | Lubiprostone vs Senna in postoperative orthopedic surgery patients with opioid-induced constipation:A double-blind,active-comparator trial显示文摘AIM:To investigate the efficacy of lubiprostone compared to Senna on bowel symptoms and constipation in post-operative orthopedic patients treated with opioids.METHODS:In this double blind,randomized,active comparator trial,adults who required opioids for analgesia following orthopedic procedures and who were admitted in inpatient rehabilitation were randomized following baseline assessments to lubiprostone(Amitza),orally twice aday or Senna(generic)two capsules administered daily for six days.Subjects were assessed using the patient assessment of constipation(PAC)-symptoms(PAC-SYM)and the PAC-quality of life(PAC-QOL)scales measured at baseline and Day 7;Subjects were assessed daily for secondary measures included the Bristol stool scale bowel consistency,specific bowel symptom score(Nausea,cramping,straining,completeness,abdominal pain,time per lavatory attempt,assistance needed),adverse events and rescue medications required.Function was measured using the functional independence measure(FIM)at admission and discharge;length of stay(LOS)and missed treatments due to gastrointestinal symptoms were also assessed.RESULTS:64 adults were enrolled;56 participants(28 in each group)had baseline and follow up measures and were included in the intention to treat(ITT)analyses.43 participants completed the study,21 in the active lubiprostone and 22 in the active Senna group.The mean age of the participants was 71.5years(SD=11.4 years,range:28-96 years).In the ITT analyses,participants showed significant improvement in bowel symptoms as measured by the PACSYM(mean±SD,-0.28±0.60,range:-1-2.33)and PAC-QOL(mean±SD,0.33±0.81,range:-1.5-2.0)over time,but there were no significant differences between the lubiprostone and Senna groups in mean change in the PAC-SYM(-0.20±0.60 vs-0.36±0.61,P=0.61 respectively)or the PAC-QOL(0.29±0.76 vs0.37±0.87,P=0.61 respectively).The mean change in each bowel symptom also did not significantly differ between treatment groups on ITT analyses,except for completeness of bowel movement,with the Senna group showing greater negative mean change in bowel movement completeness(-0.56±1.01 vs-2.00±1.41,P=0.03)and for reduction of abdominal pain,favoring Senna(-0.14±0.73 vs-0.73±1.08,P=0.04).Fifteen(75%)participants in the lubiprostone and in the Senna group requested rescue treatments.Participants made significant functional improvement from admission to discharge over a median LOS of 12 d,with a mean FIM change of 29.13±13.58 and no significant between group differences(27.0±9.2 vs 31.5±16.6,P=0.27).CONCLUSION:Both lubiprostone and Senna improved constipation-related symptoms and QOL in opioid-induced constipation,with no significant between-group differences. | Christina M Marciniak Santiago Toledo Jungwhalia Lee Michael Jesselson Jillian Bateman Benjamin Grover Joy Tierny | 2014 | World Journal of Gastroenterology2014，20，43： | 7 |
| 7 | Does physical therapy and rehabilitation improve outcomes for diabetic foot ulcers?显示文摘One of the most common and serious complications of diabetes mellitus is ulceration of the foot. Among persons with diabetes, 12%-25% will present to a healthcare institution for a foot disorder during their lifespan. Despite currently available medical and surgical treatments, these are still the most common diabetes-related cause of hospitalization and of lower extremity amputations. Thus, many adjunctive and complementary treatments have been developed in an attempt to improve outcomes. We herein review the available literature on the effectiveness of several treatments, including superficial and deep heaters, electro-therapy procedures, prophylactic methods, exercise and shoe modifications, on diabetic foot wounds. Overall, although physical therapy modalities seem to be useful in the treatment of diabetic foot wounds, further randomized clinical studies are required. | Yasemin Turan Bulent M Ertugrul Benjamin A Lipsky Kevser Bayraktar | 2015 | World Journal of Experimental Medicine2015，5，2： | 7 |

| 9 | Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed. | Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee | 2014 | World Journal of Clinical Oncology2014，5，2： | 5 |
| 10 | Late biliary complications in human alveolar echinococcosis are associated with high mortality显示文摘AIM:To evaluate the incidence of late biliary complications in non-resectable alveolar echinococcosis(AE)under long-term chemotherapy with benzimidazoles.METHODS:Retrospective analysis of AE patients with biliary complications occurring more than three years after the diagnosis of AE.We compared characteristics of patients with and without biliary complications,analyzed potential risk factor for biliary complications and performed survival analyses.RESULTS:Ninety four of 148 patients with AE in Zurich had non-resectable AE requiring long-term benzimidazole chemotherapy,of which 26(28%)patients developed late biliary complications.These patients had a median age of 55.5(35.5-65)years at diagnosis of AE and developed biliary complications after 15(8.25-19)years of chemotherapy.The most common biliary complications during long-term chemotherapy were late-onset cholangitis(n=14),sclerosing cholangitis-like lesions(n=8),hepatolithiasis(n=5),affection of the common bile duct(n=7)and secondary biliary cirrhosis(n=7).Thirteen of the 26 patients had undergone surgery(including 12 resections)before chemotherapy.Previous surgery was a risk factor for late biliary complications in linear regression analysis(P=0.012).CONCLUSION:Late biliary complications can be observed in nearly one third of patients with non-resectable AE,with previous surgery being a potential risk factor.After the occurrence of late biliary complications,the median survival is only 3 years,suggesting that late biliary complications indicate a poor prognostic outcome. | Pascal Frei Benjamin Misselwitz Meher K Prakash Alain M Schoepfer Bettina M Prinz Vavricka Beat Müllhaupt Michael Fried Kuno Lehmann Rudolf W Ammann Stephan R Vavricka | 2014 | World Journal of Gastroenterology2014，20，19： | 5 |
| 11 | Prognostic value of pre-treatment F-18-FDG PET-CT in patients with hepatocellular carcinoma undergoing radioembolization显示文摘AIM To evaluate the value of pre-treatment 18F-FDG PET/CT in patients with HCC following liver radioembolization.METHODS We identified 34 patients with HCC who underwent an FDG PET/CT scan prior to hepatic radioembolization at our institution between 2009 and 2013. Patients wereseen in clinic one month after radioembolization and then at 2-3 mo intervals. We assessed the influence of FDG tumor uptake on outcomes including local liver control(LLC), distant liver control(DLC), time to distant metastases(DM), progression free survival(PFS) and overall survival(OS).RESULTS The majority of patients were males(n = 25, 74%), and had Child Pugh Class A(n = 31, 91%), with a median age of 68 years(46-84 years). FDG-avid disease was found in 19(56%) patients with SUVmax ranging from 3 to 20. Female patients were more likely to have an FDG-avid HCC(P = 0.02). Median follow up of patients following radioembolization was 12 months(1.2-62.8 mo). FDG-avid disease was associated with a decreased 1 year LLC, DLC, DM and PFS(P < 0.05). Using multivariate analysis, FDG avidity predicted for LLC, DLC, and PFS(all P < 0.05).CONCLUSION In this retrospective study, pre-treatment HCC FDGavidity was found to be associated with worse LLC, DLC, and PFS following radioembolization. Larger studies are needed to validate our initial findings to assess the role of F-18-FDG PET/CT scans as biomarker for patients with HCC following radioembolization. | Yazan Abuodeh Arash O Naghavi Kamran A Ahmed Puja S Venkat Youngchul Kim Bela Kis Junsung Choi Benjamin Biebel Jennifer Sweeney Daniel A Anaya Richard Kim Mokenge Malafa Jessica M Frakes Sarah E Hoffe Ghassan El-Haddad | 2016 | World Journal of Gastroenterology2016，22，47： | 3 |
| 12 | Endocrine radionuclide scintigraphy with fusion single photon emission computed tomography/computed tomography显示文摘AIM: To review the benefits of single photon emission computed tomography(SPECT)/computed tomography(CT) hybrid imaging for diagnosis of various endocrine disorders.METHODS: We performed MEDLINE and Pub Med searches using the terms: 'SPECT/CT'; 'functional anatomic mapping'; 'transmission emission tomography'; 'parathyroid adenoma'; 'thyroid cancer'; 'neuroendocrine tumor'; 'adrenal'; 'pheochromocytoma'; 'paraganglioma'; in order to identify relevant articles published in English during the years 2003 to 2015. Reference lists from the articles were reviewed to identify additional pertinent articles. Retrieved manuscripts(case reports, reviews, meta-analyses and abstracts) concerning the application of SPECT/CT to endocrine imaging were analyzed to provide a descriptive synthesis of the utility of this technology.RESULTS: The emergence of hybrid SPECT/CT camera technology now allows simultaneous acquisition of combined multi-modality imaging, with seamless fusion of three-dimensional volume datasets. The usefulness of combining functional information to depict the biodistribution of radiotracers that map cellular processes of the endocrine system and tumors of endocrine origin, with anatomy derived from CT, has improved the diagnostic capability of scintigraphy for a range of disorders of endocrine gland function. The literature describes benefits of SPECT/CT for ^(99m)Tc-sestamibi parathyroid scintigraphy and ^(99m)Tc-pertechnetate thyroid scintigraphy, ^(123)I- or ^(131)I-radioiodine for staging of differentiated thyroid carcinoma, ^(111)In- and ^(99m)Tclabeled somatostatin receptor analogues for detection of neuroendocrine tumors, ^(131)I-norcholesterol(NP-59) scans for assessment of adrenal cortical hyperfunction, and ^(123)I- or ^(131)I-metaiodobenzylguanidine imaging for evaluation of pheochromocytoma and paraganglioma.CONCLUSION: SPECT/CT exploits the synergism between the functional information from radiopharmaceutical imaging and anatomy from CT, translating to improved diagnostic accuracy and meaningful impact on patient care. | Ka-Kit Wong Arpit Gandhi Benjamin L Viglianti Lorraine M Fig Domenico Rubello Milton D Gross | 2016 | World Journal of Radiology2016，8，6： | 3 |
| 13 | Heparin resistance in severe thermal injury:a prospective cohort study显示文摘Background:Low molecular-weight heparin(LMWH)is routinely administered to burn patients for thromboprophylaxis.Some studies have reported heparin resistance,yet the mechanism(s)and prevalence have not been systematically studied.We hypothesized that nucleosomes,composed of histone structures with associated DNA released from injured tissue and activated immune cells in the form of neutrophil extracellular traps(NETs or NETosis),neutralize LMWH resulting in suboptimal anticoagulation,assessed by reduction in anti-factor Xa activity.Methods:Blood was sampled from>15%total body surface area(TBSA)burn patients receiving LMWH on days 5,10 and 14.Peak anti-factor Xa(AFXa)activity,anti-thrombin(ATIII)activity,cellfree DNA(cfDNA)levels and nucleosome levels were measured.Mixed effects regression was adjusted for multiple confounders,including injury severity and ATIII activity,and was used to test the association between nucleosomes and AFXa.Results:A total of 30 patients with severe burns were included.Mean TBSA 43%(SD 17).Twentythree(77%)patients were affected by heparin resistance(defined by AFXa activity<0.2 IU/mL).Mean peak AFXa activity across samples was 0.18 IU/mL(SD 0.11).Mean ATIII was 81.9%activity(SD 20.4).Samples taken at higher LWMH doses were found to have significantly increased AFXa activity,though the effect was not observed at all doses,at 8000 IU no samples were heparin resistant.Nucleosome levels were negatively correlated with AFXa(r=−0.29,p=0.050)consistent with the hypothesis.The final model,with peak AFXa as the response variable,was adjusted for nucleosome levels(p=0.0453),ATIII activity(p=0.0053),LMWH dose pre-sample(p=0.0049),drug given(enoxaparin or tinzaparin)(p=0.03),and other confounders including severity of injury,age,gender,time point of sample.Conclusions:Heparin resistance is a prevalent issue in severe burns.Nucleosome levels were increased post-burn,and showed an inverse association with AFXa consistent with the hypothesis that they may interfere with the anticoagulant effect of heparin in vivo and contribute to heparin resistance.Accurate monitoring of AFXa activity with appropriate therapy escalation plans are recommended with dose adjustment following severe burn injury. | Liam D Cato Benjamin Bailiff Joshua Price Christos Ermogeneous Jon Hazeldine William Lester Gillian Lowe Christopher Wearn Jonathan RB Bishop Janet M Lord Naiem Moiemen Paul Harrison | 2021 | Burns & Trauma2021，9，1： | 3 |

| 15 | Risk-adjustment in hepatobiliarypancreatic surgery显示文摘AIM: The present study evaluates the performance of the POSSUM, the American Society of Anesthetists (ASA),APACHE and Childs classification in predicting mortality and morbidity in hepatopancreaticobiliary (HPB) surgery.We describe especially the limitations and advantages of risk in stratifying the patients.METHODS: We investigated 177 randomly chosen patients undergoing eledive complex HPB surgery in a single institution with a total of 71 pre-operative and intra-operative risk factors.Primary endpoint was in-hospital mortality and morbidity.Ordered logistic regression analysis was used to identify individual predictors of operative morbidity and mortality.RESULTS: The operative mortality in the series was 3.95% .This compared well with the p-POSSUM and APACHE predicted mortality of 4.31% and 4.29% respectively. Postoperative complications amounted to 45% with 24 (13.6%)patients having a major adverse event. On multivariate analysis the pre-operative POSSUM physiological score (OR = 1.18,P = 0.009) was superior in predicting complications compared to the ASA (P = 0.108), APACHE (P = 0.117)or Childs classification (P = 0.136). In addition, serum sodium, creatinine, international normalized ratio (INR),pulse rate, and intra-operative blood loss were independent risk factors. A combination of the POSSUM variables and INR offered the optimal combination of risk factors for risk prognostication in HPB surgery.CONCLUSION: Morbidity for elective HPB surgery can be accurately predicted and applied in everyday surgical practice as an adjunct in the process of informed consent and for effective allocation of resources for intensive and high-dependency care facilities. | Hemant M Kocher Paris P Tekkis Palepu Gopal Ameet G Patel Simon Cottam Irving S Benjamin | 2005 | World Journal of Gastroenterology2005，11，16： | 3 |

| 17 | 一种房颤风险评分系统的建立(Framingham心脏研究):基于社区的队列研究显示文摘背景房颤导致了发病率和病死率的显著上升。本研究旨在建立一种预测个体罹患房颤绝对风险的风险评分系统,并提供研究人员评价新危险因素的流程。方法作者评估了Framingham心脏研究中于1968年6月至1987年9月间进行了8044次检测的4764例参与者(55%为女性,年龄45~95岁)。此后,参与者被随访至房颤首发,随访期最长达10年。多变量Coxi回归确认出1(1年内罹患房颤的临床危险因素。次级分析纳入了常规超声心动图检测指标(5152例4参与者,7156次检测)对房颤风险进行再分层评估,并评价超声检测指标能否提高风险预测能力。结果4764例参与者中的457例4(10%)罹患房颤。年龄、性别、体重指数、收缩压、降压治疗、PR间期、有临床意义的心脏杂音及心力衰竭与房颤相关,并被纳入了风险评分模型(除体重指数P=0.08外,其余均为P〈0.05),模型的C统计量为0.78(95%CI0.76~0.80)。10年房颤风险随年龄变化:年龄〈65岁的人群中53例(1%)风险高于15%,而〉65岁的人群中为783例(27%)。为提高预测能力而纳入超声检测指标仅使模型C统计量略微增高,由0.78(95%C10.75~0.80)增至0.79(95%CI0.77~0.82:P=0.005)。超声心动图检测指标并不能改善风险再分层评估(P=0.18)。结论基于社区医疗中易得的临床因素建立的风险评分系统,有助于确认社区个体罹患房颤的风险,评估技术或标志物能否改善风险预测,以及针对高危个体采取预防措施。 | Renate B Schnabel Lisa M Sullivan Daniel Levy Michael J Pencina Joseph M Massaro Ralph B D'Agostino Sr Christopher Newton-Cheh Jennifer F Yamamoto Jared W Magnani Thomas M Tadros William B Kannel Thomas J Wang Patrick T Ellinor Philip A Wolf Ramachanclran S Vasan Emelia J Benjamin 黄刚(译) | 2009 | 世界临床医学2009，，9： | 2 |
| 18 | Pharmacological inhibition of diacylglycerol acyltransferase-1 and insights into postprandial gut peptide secretion显示文摘AIM To examine the role that enzyme Acyl-CoA:diacylglycerol acyltransferase-1(DGAT1) plays in postprandial gut peptide secretion and signaling.METHODS The standard experimental paradigm utilized to evaluate the incretin response was a lipid challenge.Following a lipid challenge,plasma was collected via cardiac puncture at each time point from a cohort of 5-8 mice per group from baseline at time zero to 10 h.Incretin hormones [glucagon like peptide-1(GLP-1),peptide tyrosine-tyrosine(PYY) and glucose dependent insulinotropic polypeptide(GIP)] were then quantitated.The impact of pharmacological inhibition of DGAT1 on the incretin effect was evaluated in WT mice.Additionally,a comparison of loss of DGAT1 function either by genetic ablation or pharmacological inhibition.To further elucidate the pathways and mechanisms involved in the incretin response to DGAT1 inhibition,other interventions [inhibitors of dipeptidyl peptidase-IV(sitagliptin),pancreatic lipase(Orlistat),GPR119 knockout mice] were evaluated.RESULTS DGAT1 deficient mice and wildtype C57/BL6J mice werelipid challenged and levels of both active and total GLP-1 in the plasma were increased.This response was further augmented with DGAT1 inhibitor PF-04620110 treated wildtype mice.Furthermore,PF-04620110 was able to dose responsively increase GLP-1 and PYY,but blunt GIP at all doses of PF-04620110 during lipid challenge.Combination treatment of PF-04620110 and Sitagliptin in wildtype mice during a lipid challenge synergistically enhanced postprandial levels of active GLP-1.In contrast,in a combination study with Orlistat,the ability of PF-04620110 to elicit an enhanced incretin response was abrogated.To further explore this observation,GPR119 knockout mice were evaluated.In response to a lipid challenge,GPR119 knockout mice exhibited no increase in active or total GLP-1 and PYY.However,PF-04620110 was able to increase total GLP-1 and PYY in GPR119 knockout mice as compared to vehicle treated wildtype mice.CONCLUSION Collectively,these data provide some insight into the mechanism by which inhibition of DGAT1 enhances intestinal hormone release. | Benjamin S Maciejewski Tara B Manion Claire M Steppan | 2017 | World Journal of Gastrointestinal Pathophysiology2017，8，4： | 2 |
| 19 | Knowledge, perception and practices about malaria, climate change, livelihoods and food security among rural communities of central Tanzania显示文摘Background:Understanding the interactions between malaria and agriculture in Tanzania is of particular significance when considering that they are the major sources of illness and livelihoods.The objective of this study was to determine knowledge,perceptions and practices as regards to malaria,climate change,livelihoods and food insecurity in a rural farming community in central Tanzania.Methods:Using a cross-sectional design,heads of households were interviewed on their knowledge and perceptions on malaria transmission,symptoms and prevention and knowledge and practices as regards to climate change and food security.Results:A total of 399 individuals(mean age=39.8±15.5 years)were interviewed.Most(62.41%)of them had attained primary school education and majority(91.23%)were involved in crop farming activities.Nearly all(94.7%)knew that malaria is acquired through a mosquito bite.Three quarters(73%)reported that most people get sick from malaria during the rainy season.About 50%of the respondents felt that malaria had decreased during the last 10 years.The household coverage of insecticide treated mosquito nets(ITN)was high(95.5%).Ninety-six percent reported to have slept under a mosquito net the previous night.Only one in four understood the official Kiswahili term(Mabadiliko ya Tabia Nchi)for climate change.However,there was a general understanding that the rain patterns have changed in the past 10 years.Sixty-two percent believed that the temperature has increased during the same period.Three quarters of the respondents reported that they had no sufficient production from their own farms to guarantee food security in their household for the year.Three quarters(73.0%)reported to having food shortages in the past five years.About half said they most often experienced severe food shortage during the rainy season.Conclusion:Farming communities in Kilosa District have little knowledge on climate change and its impact on malaria burden.Food insecurity is common and community-based strategies to mitigate this need to be established.The findings call for an integrated control of malaria and food insecurity interventions. | Benjamin K Mayala Carolyn A Fahey Dorothy Wei Maria M Zinga Venera M Bwana Tabitha Mlacha Susan F Rumisha Grades Stanley Elizabeth H Shayo Leonard EG Mboera | 2015 | Infectious Diseases of Poverty2015，4，1： | 2 |
