2在血压控制不良的高血压患者中使用数字化干预的家庭和在线血压管理:随机对照试验显示文摘HOME BP试验(The home and online management and evaluation of blood pressure)的目的是评估在初级预防中结合自我监测和自我管理的数字化干预在高血压管理中的作用。研究者纳入英国76个治疗中心经过治疗但血压控制不好(>140/90 mm Hg, 1 mm Hg=0.133 kPa)并能上网的患者622例,进行自动确定主要终点的公开随机对照试验。McMa-nus RJ Little P Stuart B Morton K Raftery J Kelly J Bradbury K Zhang J Zhu S Murray E May CR Mair FS Michie S Smith P Band R Ogburn E AllenJ Rice C Nut-tall J Williams B Yardley L 陈嘉睿(译) 叶鹏(审校) 2021中华高血压杂志2021,29,5:15
3高危患者目标血压与心血管病预后显示文摘指南推荐血压目标值应〈140/90 mmHg(1mmHg=0.133kPa)以减少心血管事件的发生。但与其他心血管病预后(如冠状动脉事件)相比,包括脑卒中及心力衰竭在内的心血管病预后与收缩压下降关系更密切。一些心血管事件(如冠状动脉事件)风险在收缩压低时亦增高,风险-收缩压关系呈J形曲线,而脑卒中与血压不是J形曲线关系。B?hm M Schumacher H Teo KK Lonn EM Mahfoud F Mann JF Mancia G Redon J Schmieder RE Sliwa K Weber MA Williams BYusuf S 曲浥晨 叶鹏 2017中华高血压杂志2017,25,6:14

5Factors associated with time to laparoscopic cholecystectomy for acute cholecystitis显示文摘AIM: To determine patient and process of care factors associated with performance of timely laparoscopic cholecystectomy for acute cholecystitis. METHODS: A retrospective medical record review of 88 consecutive patients with acute cholecystitis was conducted. Data collected included demographic data, co-morbidities, symptoms and physical findings at presentation, laboratory and radiological investigations, length of stay, complications, and admission service (medical or surgical). Patients not undergoing cholecystectomy during this hospitalization were excluded from analysis. Hierarchical generalized linear models were constructed to assess the association of pre-operative diagnostic procedures, presenting signs, and admitting service with time to surgery.RESULTS: Seventy cases met inclusion and exclusion criteria, among which 12 were admitted to the medical service and 58 to the surgical service. Mean ± SD time to surgery was 39.3 ± 43 h, with 87% of operations performed within 72 h of hospital arrival. In the adjusted models, longer time to surgery was associated with number of diagnostic studies and endoscopic retrograde cholangio-pancreatography (ERCP, P = 0.01) as well with admission to medical service without adjustment for ERCP (P < 0.05). Patients undergoing both magnetic resonance cholangiopancreatography (MRCP) and computed tomography (CT) scans experienced the longest waits for surgery. Patients admitted to the surgical versus medical service underwent surgery earlier (30.4 ± 34.9 vs 82.7 ± 55.1 h, P < 0.01), had less post-operative complications (12% vs 58%, P < 0.01), and shorter length of stay (4.3 ± 3.4 vs 8.1 ± 5.2 d, P < 0.01).CONCLUSION: Admission to the medical service and performance of numerous diagnostic procedures, ERCP, or MRCP combined with CT scan were associated with longer time to surgery. Expeditious performance of ERCP and MRCP and admission of medically stable patients with suspected cholecystitis to the surgical service to speed up time to surgery should be considered.Chris N Daniak David Peretz Jonathan M Fine Yun Wang Alan K Meinke William B Hale 2008World Journal of Gastroenterology2008,14,7:13
6Mycophenolate mofetil for drug-induced vanishing bile duct syndrome显示文摘Amoxicillin/clavulanate is associated with liver injury, mostly of a cholestatic pattern. While outcomes are usually benign, progression to cirrhosis and death has been reported. The role of immunosuppressive therapy for patients with a protracted course is unclear. We report the case of an elderly patient who developed prolonged cholestasis secondary to amoxicillin/clavulanate. Vanishing bile duct syndrome was confirmed by sequential liver biopsies. The patient responded to prednisone treatment, but could not be weaned off corticosteroids, even when azathioprine was added. Complete withdrawal of both prednisone and azathioprine was possible by using mycophenolate mofetil, an inosine monophosphate dehydrogenase inhibitor. Sustained remission has been maintained for more than 3 years with low-dose mycophenolate mofetil.S Simona Jakab A Brian West Dennis M Meighan Robert S Brown Jr William B Hale 2007World Journal of Gastroenterology2007,13,45:8
7Operative complications and economic outcomes of cholecystectomy for acute cholecystitis显示文摘BACKGROUND Recent management of acute cholecystitis favors same admission(SA)or emergent cholecystectomy based on overall shorter hospital stay and therefore cost savings.We adopted the practice of SA cholecystectomy for the treatment of acute cholecystitis at our tertiary care center and wanted to evaluate the economic benefit of this practice.We hypothesized that the existence of complications,particularly among patients with a higher degree of disease severity,during SA cholecystectomy could negate the cost savings.AIM To compare complication rates and hospital costs between SA vs delayed cholecystectomy among patients admitted emergently for acute cholecystitis.METHODS Under an IRB-approved protocol,complications and charges for were obtained for SA,later after conservative management(Delayed),or elective cholecystectomies over an 8.5-year period.Patients were identified using the acute care surgery registry and billing database.Data was retrieved via EMR,operative logs,and Revenue Cycle Operations.The severity of acute cholecystitis was graded according to the Tokyo Guidelines.TG18 categorizes acute cholecystitis by Grades 1,2,and 3 representing mild,moderate,and severe,respectively.Comparisons were analyzed withχ2,Fisher’s exact test,ANOVA,ttests,and logistic regression;significance was set at P<0.05.RESULTS Four hundred eighty-six(87.7%)underwent a SA while 68 patients(12.3%)received Delayed cholecystectomy.Complication rates were increased after SA compared to Delayed cholecystectomy(18.5%vs 4.4%,P=0.004).The complication rates of patients undergoing delayed cholecystectomy was similar to the rate for elective cholecystectomy(7.4%,P=0.35).Mortality rates were 0.6%vs 0%for SA vs Delayed.Patients with moderate disease(Tokyo 2)suffered more complications among SA while none who were delayed experienced a complication(16.1%vs 0.0%,P<0.001).Total hospital charges for SA cholecystectomy were increased compared to a Delayed approach($44500±$59000 vs$35300±$16700,P=0.019).The relative risk of developing a complication was 4.2x[95%confidence interval(CI):1.4-12.9]in the SA vs Delayed groups.Among eight patients(95%CI:5.0-12.3)with acute cholecystitis undergoing SA cholecystectomy,one patient will suffer a complication.CONCLUSION Patients with Tokyo Grade 2 acute cholecystitis had more complications and increased hospital charges when undergoing SA cholecystectomy.This data supports a selective approach to SA cholecystectomy for acute cholecystitis.Christopher P Rice Krishnamurthy B Vaishnavi Celia Chao Daniel Jupiter August B Schaeffer Whitney R Jenson Lance W Griffin William J Mileski 2019World Journal of Gastroenterology2019,25,48:8
8Immunohistochemical expression of SP-NK-1R-EGFR pathway and VDR in colonic inflammation and neoplasia显示文摘AIM:To determine the expression of neurokinin-1receptor(NK-1R),phosphorylated epidermal growth factor receptor(p EGFR),cyclooxygenase-2(Cox-2),and vitamin D receptor(VDR)in normal,inflammatory bowel disease(IBD),and colorectal neoplasia tissues from Puerto Ricans.METHODS:Tissues from patients with IBD,colitisassociated colorectal cancer(CAC),sporadic dysplasia,and sporadic colorectal cancer(CRC),as well as normal controls,were identified at several centers in Puerto Rico.Archival formalin-fixed,paraffin-embedded tissues were de-identified and processed by immunohistochemistry for NK-1R,p EGFR,Cox-2,and VDR.Pictures of representative areas of each tissues diagnosis were taken and scored by three observers using a4-point scale that assessed intensity of staining.Tissues with CAC were further analyzed by photographing representative areas of IBD and the different grades of dysplasia,in addition to the areas of cancer,within each tissue.Differences in the average age between the five patient groups were assessed with one-way analysis of variance and Tukey-Kramer multiple comparisons test.The mean scores for normal tissues and tissues with IBD,dysplasia,CRC,and CAC were calculatedand statistically compared using one-way analysis of variance and Dunnett’s multiple comparisons test.Correlations between protein expression patterns were analyzed with the Pearson’s product-moment correlation coefficient.Data are presented as mean±SE.RESULTS:On average,patients with IBD were younger(34.60±5.81)than normal(63.20±6.13,P<0.01),sporadic dysplasia(68.80±4.42,P<0.01),sporadic cancer(74.80±4.91,P<0.001),and CAC(57.50±5.11,P<0.05)patients.NK-1R in cancer tissue(sporadic CRC,1.73±0.34;CAC,1.57±0.53)and sporadic dysplasia(2.00±0.45)were higher than in normal tissues(0.73±0.19).p EGFR was significantly increased in sporadic CRC(1.53±0.43)and CAC(2.25±0.47)when compared to normal tissue(0.07±0.25,P<0.05,P<0.001,respectively).Cox-2 was significantly increased in sporadic colorectal cancer(2.20±0.23 vs 0.80±0.37 for normal tissues,P<0.05).In comparison to normal(2.80±0.13)and CAC(2.50±0.33)tissues,VDR was significantly decreased in sporadic dysplasia(0.00±0.00,P<0.001 vs normal,P<0.001 vs CAC)and sporadic CRC(0.47±0.23,P<0.001 vs normal,P<0.001 vs CAC).VDR levels negatively correlated with NK-1R(r=-0.48)and p EGFR(r=-0.56)in normal,IBD,sporadic dysplasia and sporadic CRC tissue,but not in CAC.CONCLUSION:Immunohistochemical NK-1R and p EGFR positivity with VDR negativity can be used to identify areas of sporadic colorectal neoplasia.VDR immunoreactivity can distinguish CAC from sporadic cancer.Raymond A Isidro Myrella L Cruz Angel A Isidro Axel Baez Axel Arroyo William A González-Marqués Carmen González-Keelan Esther A Torres Caroline B Appleyard 2015World Journal of Gastroenterology2015,21,6:7
9三级高血压单位5100例患者低血钾症与原发性醛固酮增多症的发病率显示文摘常伴有低血钾症的原发性醛固酮增多症(原醛)被认为是一个少见病。广泛筛查高血压患者发现正常血钾的原醛发生率增加。许多研究报道原醛低血钾症的发生率,相反,低血钾症患者中原醛的发生率并不明确。在该回顾性观察研究,研究者探讨了高血压患者中低钾的发生率以及低血钾症合并高血压患者中原醛的发生率。赵狄(译) 刘莉(审校) Burrello J Monticone S Losano I Cavaglià G Buffolo F Tetti M Covella M Rabbia F Veglio F Pasini B Williams TA Mulatero P 2020中华高血压杂志2020,28,3:7

11Endoscopic balloon catheter dilatation via retrograde or static technique is safe and effective for cricopharyngeal dysfunction显示文摘AIM To evaluate the safety and efficacy of upper esophageal sphincter(UES) dilatation for cricopharyngeal(CP) dysfunction. To determine if:(1) indication for dilatation; or(2) technique of dilatation correlated with symptom improvement.METHODS All balloon dilatations performed at our institution from over a 3-year period were retrospectively analyzed for demographics, indication and dilatation site. All dilatations involving the UES underwent further review to determine efficacy, complications, and factors that predict success. Dilatation technique was separated into static(stationary balloon distention) and retrograde(brusque pull-back of a fully distended balloon across the UES).RESULTS Four hundred and eighty-eight dilatations were reviewed. Thirty-one patients were identified who underwent UES dilatation. Median age was 63 years(range 27-81)and 55% of patients were male. Indications included dysphagia(28 patients), globus sensation with evidence of UES dysfunction(2 patients) and obstruction to echocardiography probe with cricopharyngeal(CP)bar(1 patient). There was evidence of concurrent oropharyngeal dysfunction in 16 patients(52%) and a small Zenker's diverticula(≤ 2 cm) in 7 patients(23%). Dilator size ranged from 15 mm to 20 mm. Of the 31 patients, 11 had dilatation of other esophageal segments concurrently with UES dilatation and 20 had UES dilatation alone.Follow-up was available for 24 patients for a median of 2.5 mo(interquartile range 1-10 mo), of whom 19 reported symptomatic improvement(79%). For patients undergoing UES dilatation alone, follow-up was available for 15 patients, 12 of whom reported improvement(80%).Nineteen patients underwent retrograde dilatation(84%response) while 5 patients had static dilatation(60%response); however, there was no significant difference in symptom improvement between the techniques(P = 0.5).Successful symptom resolution was also not significantly affected by dilator size, oropharyngeal dysfunction,Zenker's diverticulum, age or gender(P > 0.05). The only complication noted was uvular edema and a shallow ulcer after static dilatation in one patient, which resolved spontaneously and did not require hospital admission.CONCLUSION UES dilatation with a through-the-scope balloon by either static or retrograde technique is safe and effective for the treatment of dysphagia due to CP dysfunction. To our knowledge, this is the first study evaluating retrograde balloon dilatation of the UES.Vinay Chandrasekhara Joyce Koh Lakshmi Lattimer Kerry B Dunbar William J Ravich John O Clarke 2017World Journal of Gastrointestinal Endoscopy2017,9,4:6
12The dependences of osteocyte network on bone compartment, age, and disease显示文摘Osteocytes, the most abundant bone cells, form an interconnected network in the lacunar-canalicular pore system(LCS) buried within the mineralized matrix, which allows osteocytes to obtain nutrients from the blood supply, sense external mechanical signals, and communicate among themselves and with other cells on bone surfaces. In this study, we examined key features of the LCS network including the topological parameter and the detailed structure of individual connections and their variations in cortical and cancellous compartments, at different ages, and in two disease conditions with altered mechanosensing(perlecan deficiency and diabetes).LCS network showed both topological stability, in terms of conservation of connectivity among osteocyte lacunae(similar to the ‘‘nodes' ' in a computer network), and considerable variability the pericellular annular fluid gap surrounding lacunae and canaliculi(similar to the ‘‘bandwidth'' of individual links in a computer network). Age, in the range of our study(15–32 weeks), affected only the pericellular fluid annulus in cortical bone but not in cancellous bone. Diabetes impacted the spacing of the lacunae, while the perlecan deficiency had a profound influence on the pericellular fluid annulus. The LCS network features play important roles in osteocyte signaling and regulation of bone growth and adaptation.Xiaohan Lai Christopher Price Shannon Modla William R Thompson Jeffrey Caplan Catherine B Kirn-Safran Liyun Wang 2015Bone Research2015,3,2:6

17Review of screening for pancreatic cancer in high risk individuals显示文摘Pancreatic cancer is difficult to diagnose at an early stage and is associated with a very poor survival.Ten percent of pancreatic cancers result from genetic susceptibility and/or familial aggregation.Individuals from families with multiple affected first-degree relatives and those with a known cancer-causing genetic mutation have been shown to be at much higher risk of developing pancreatic cancer.Recent efforts have focused on detecting disease at an earlier stage to improve survival in these high-risk groups.This article reviews high-risk groups,screening methods,and current screening programs and their results.Alina Stoita Ian D Penman David B Williams 2011World Journal of Gastroenterology2011,17,19:4

19Variations in zonal fruit starch concentrations of apples – a developmental phenomenon or an indication of ripening?显示文摘Patterns of starch hydrolysis in stem,equatorial,and calyx zones of‘Honeycrisp’and‘Empire’apples(Malus sylvestris(L.)Mill var.domestica(Borkh.)Mansf.)during maturation and ripening,and in‘Gala’apples in response to propylene or 1-methylcyclopropene(1-MCP)treatments after harvest,were studied.Differences in zonal starch concentrations were found for‘Empire’and‘Gala’fruits,but not for‘Honeycrisp’.During maturation and ripening of‘Empire’,the concentration of starch was highest in the calyx end and lowest in the stem region.Differences in rates of starch hydrolysis among zones were not detected.‘Honeycrisp’and‘Empire’had the highest concentration of sorbitol in the calyx region,whereas it was highest in the stem-end region in‘Gala’.The distribution differences of glucose,fructose,and sucrose were similar in all three cultivars;higher fructose and glucose concentrations in the stem region,and higher sucrose concentrations in the calyx end of the fruit.Postharvest treatment of‘Gala’with propylene did not affect the internal ethylene concentration of the fruit but 1-MCP markedly inhibited it.Starch concentrations were highest in the calyx end but gradients of starch among zones were not changed by postharvest treatment.The rate of hydrolysis was slowed by 1-MCP treatment,but was unaffected by propylene.Postharvest treatments influenced sorbitol,glucose,and fructose concentrations.Patterns of starch concentration among the zones did not confirm differences in ripening,but reflected its uneven distribution throughout the fruit during development.Therefore,measured differences in zonal starch are most likely related to starch accumulation during fruit development,rather than differences in rates of starch degradation during ripening.Franziska C Doerflinger William B Miller Jacqueline F Nock Christopher B Watkins 2015Horticulture Research2015,2,1:3
