1Stroke mechanisms and outcomes of isolated symptomatic basilar artery stenosis显示文摘background While diffuse atherosclerotic disease affecting the posterior circulation has been described extensively,the prevalence,natural history and angiographic characteristics of isolated symptomatic basilar artery stenosis(ISBAS)remain unknown.Methods We reviewed our prospective institutional database to identify patients with≥50% symptomatic basilar artery(BA)stenosis without significant atherosclerotic burden in the vertebral or posterior cerebral arteries.Stroke mechanism,collateral circulation,and degree and length of stenosis were analysed.The primary outcome was time from index event to new transient ischaemic attack(TIA),acute ischaemic stroke(AIS)or death.Other outcome variables included modified Rankin Scale(mRS)score on discharge and last follow-up.results Of 6369 patients with AIS/TIA,91(1.43%)had ISBAS.Seventy-three(80.2%)patients presented with AIS and 18(19.8%)with TIA.Twenty-nine(31.9%)were women and the median age was 66.8±13.6 years.The mean follow-up time was 2.7 years.The most common stroke mechanism was artery-to artery thromboembolism(45.2%),followed by perforator occlusion(28.7%)and flow-dependent/hypoperfusion(15.1%).The percentage of stenosis was lower in patients who had favourable outcome compared with those with mRS 3-6 on discharge(78.3±14.3 vs 86.9±14.5,p=0.007).Kaplan-Meier curves showed higher recurrence/death rates in patients with≥80% stenosis,mid-basilar location and poor collateral circulation.Approximately 13% of patients with ISBAS presented with complete BA occlusion.Conclusion ISBAS is an uncommon(1.43%)cause of TIA and AIS.Men in their 60s are mostly affected,and artery-to artery embolism is the most common stroke mechanism.Mid-basilar location,≥80% stenosis and poor collateral circulation are important factors associated with worse prognosis.Edgar A Samaniego Amir Shaban Santiago Ortega-Gutierrez Jorge A Roa David M Hasan Colin Derdeyn Biyue Dai Harold Adams Enrique Leira 2019Stroke & Vascular Neurology2019,4,4:10
2Cardiac adipose tissue and its relationship to diabetes mellitus and cardiovascular disease显示文摘Type-2 diabetes mellitus(T2DM) plays a central role in the development of cardiovascular disease(CVD). However, its relationship to epicardial adipose tissue(EAT) and pericardial adipose tissue(PAT) in particular is important in the pathophysiology of coronary artery disease. Owing to its close proximity to the heart and coronary vasculature, EAT exerts a direct metabolic impact by secreting proinflammatory adipokines and free fatty acids, which promote CVD locally. In this review, we have discussed the relationship between T2 DM and cardiac fat deposits, particularly EAT and PAT, which together exert a big impact on the cardiovascular health.Adam M Noyes Kirandeep Dua Ramprakash Devadoss Lovely Chhabra 2014World Journal of Diabetes2014,5,6:8
3Dementia and osteoporosis in a geriatric population: Is there a common link?显示文摘AIM To determine the existence of a common pathological link between dementia and osteoporosis through reviewing the current evidence base. METHODS This paper reviews the current literature on osteoporosis and dementia in order to ascertain evidence of a common predisposing aetiology. A literature search of Ovid MEDLINE(1950 to June 2016) was conducted. The keywords 'osteoporosis', 'osteoporotic fracture', 'dementia' and 'Alzheimer's disease'(AD) were used to determine the theoretical links with the most significant evidence base behind them. The key links were found to be vitamins D and K, calcium, thyroid disease, statins, alcohol and sex steroids. These subjects were then searched in combination with the previous terms and the resulting papers manually examined. Theoretical, in vitro and in vivo research were all used to inform this review which focuses on the most well developed theoretical common causes for dementia(predominantly Alzheimer's type) and osteoporosis.RESULTS Dementia and osteoporosis are multifaceted disease processes with similar epidemiology and a marked increase in prevalence in elderly populations. The existence of a common link between the two has been suggested despite a lack of clear pathological overlap in our current understanding. Research to date has tended to be fragmented and relatively weak in nature with multiple confounding factors reflecting the difficulties of in vivo experimentation in the population of interest. Despite exploration of various possible mechanisms in search for a link between the two pathologies, this paper found that it is possible that these associations are coincidental due to the nature of the evidence available. One finding in this review is that prior investigation into common aetiologies has found raised amyloid beta peptide levels in osteoporotic bone tissue, with a hypothesis that amyloid beta disorders are systemic disorders resulting in differing tissue manifestations. However, our findings were that the most compelling evidence of a common yet independent aetiology lies in the APOE4 allele, which is a well-established risk for AD but also carries an independent association with fracture risk. The mechanism behind this is thought to be the reduced plasma vitamin K levels in individuals exhibiting the APOE4 allele which may be amplified by the nutritional deficiencies associated with dementia, which are known to include vitamins K and D. The vitamin theory postulates that malnutrition and reduced exposure to sunlight in patients with AD leads to vitamin deficiencies. CONCLUSION Robust evidence remains to be produced regarding potential links and regarding the exact aetiology of these diseases and remains relevant given the burden of dementia and osteoporosis in our ageing population. Future research into amyloid beta, APOE4 and vitamins K and D as the most promising aetiological links should be welcomed.Candice L Downey Adam Young Emily F Burton Simon M Graham Robert J Macfarlane Eva-Maria Tsapakis Eleftherios Tsiridis 2017World Journal of Orthopedics2017,8,5:6
4Randomized trial in malignant biliary obstruction:Plastic vs partially covered metal stents显示文摘AIM:To compare efficacy and complications of par-tially covered self-expandable metal stent(pcSEMS)to plastic stent(PS)in patients treated for malignant,infrahilar biliary obstruction.METHODS:Multicenter prospective randomized clinical trial with treatment allocation to a pcWallstent(SEMS)or a 10 French PS.Palliative patients aged≥18,for infrahilar malignant biliary obstruction and a Karnofsky performance scale index>60%from 6 participating North American university centers.Primary endpoint was time to stent failure,with secondary outcomes of death,adverse events,Karnofsky performance score and short-form-36 scale administered on a three-monthly basis for up to 2 years.Survival analyses were performed for stent failure and death,with Cox proportional hazards regression models to determine significant predictive characteristics.RESULTS:Eighty-five patients were accrued over 37mo,42 were randomized to the SEMS group and 83patients were available for analyses.Time to stent failure was 385.3±52.5 d in the SEMS and 153.3±19.8 d in the PS group,P=0.006.Time to death did not differ between groups(192.3±23.4 d for SEMS vs211.5±28.0 d for PS,P=0.70).The only significant predictor was treatment allocation,relating to the time to stent failure(P=0.01).Amongst other measured outcomes,only cholangitis differed,being more common in the PS group(4.9%vs 24.5%,P=0.029).The small number of patients in follow-up limits longitudinal assessments of performance and quality of life.From an initially planned 120 patients,only 85 patients were recruited.CONCLUSION:Partially covered SEMS result in a longer duration till stent failure without increased complication rates,yet without accompanying measurable benefits in survival,performance,or quality of life.Peter L Moses Khalid M AlNaamani Alan N Barkun Stuart R Gordon Roger D Mitty M Stanley Branch Thomas E Kowalski Myriam Martel Viviane Adam 2013World Journal of Gastroenterology2013,19,46:6

6Controversies in fluid therapy: Type, dose and toxicity显示文摘Fluid therapy is perhaps the most common intervention received by acutely ill hospitalized patients; however, a number of critical questions on the efficacy and safety of the type and dose remain. In this review, recent insights derived from randomized trials in terms of fluid type, dose and toxicity are discussed. We contend that the prescription of fluid therapy is context-specific and that any fluid can be harmful if administered inappropriately. When contrasting ‘‘crystalloid vs colloid'', differences in efficacy are modest but differences in safety are significant. Differences in chloride load and strong ion difference across solutions appear to be clinically important. Phases of fluid therapy in acutely ill patients are recognized, including acute resuscitation, maintaining homeostasis, and recovery phases. Quantitative toxicity(fluid overload) is associated with adverse outcomes and can be mitigated when fluid therapy basedon functional hemodynamic parameters that predict volume responsiveness and minimization of non-essential fluid. Qualitative toxicity(fluid type), in particular for iatrogenic acute kidney injury and metabolic acidosis, remain a concern for synthetic colloids and isotonic saline, respectively. Physiologically balanced crystalloids may be the ‘‘default'' fluid for acutely ill patients and the role for colloids, in particular hydroxyethyl starch, is increasingly unclear. We contend the prescription of fluid therapy is analogous to the prescription of any drug used in critically ill patients.Robert C McDermid Karthik Raghunathan Adam Romanovsky Andrew D Shaw Sean M Bagshaw 2014World Journal of Critical Care Medicine2014,3,1:5
7Emerging concepts in liver graft preservation显示文摘The urgent need to expand the donor pool in order to attend to the growing demand for liver transplantation has obliged physicians to consider the use of suboptimal liver grafts and also to redefine the preservation strategies. This review examines the different methods of liver graft preservation, focusing on the latest advances in both static cold storage and machine perfusion(MP). The new strategies for static cold storage are mainly designed to increase the fatty liver graft preservation via the supplementation of commercial organ preservation solutions with additives. In this paper we stress the importance of carrying out effective graft washout after static cold preservation, and present a detailed discussion of the future perspectives for dynamic graft preservation using MP at different temperatures(hypothermia at 4 ℃, normothermia a t 3 7 ℃ and subnormothermia at 20 ℃- 2 5 ℃). Finally, we highlight some emerging applications of regenerative medicine in liver graft preservation. In conclusion, this review discusses the 'state of the art' and future perspectives in static and dynamic liver graft preservation in order to improve graft viability.Mohamed Bejaoui Eirini Pantazi Emma Folch-Puy Pedro M Baptista Agustín García-Gil René Adam Joan Roselló-Catafau 2015World Journal of Gastroenterology2015,21,2:5
8Clinical application of concentrated bone marrow aspirate in orthopaedics:A systematic review显示文摘AIM To examine the evidence behind the use of concentrated bone marrow aspirate(c BMA) in cartilage, bone, and tendon repair; establish proof of concept for the use of cB MA in these biologic environments; and provide the level and quality of evidence substantiating the use of cB MA in the clinical setting.METHODS We conducted a systematic review according to PRISMA guidelines. EMBASE, MEDLINE, and Web of Knowledge databases were screened for the use of cB MA in the repair of cartilage, bone, and tendon repair. We extracted data on tissue type, cB MA preparation, cB MA concentration, study methods, outcomes, and level of evidence and reported the results in tables and text.RESULTS A total of 36 studies met inclusion/exclusion criteria and were included in this review. Thirty-one of 36(86%) studies reported the method of centrifugation and preparation of cB MA with 15(42%) studies reporting either a cell concentration or an increase from baseline. Variation of c BMA application was seen amongst the studies evaluated. Twenty-one of 36(58%) were level of evidence Ⅳ, 12/36(33%) were level of evidence Ⅲ, and 3/36(8%) were level of evidence Ⅱ. Studies evaluated full thickness chondral lesions(7 studies), osteochondral lesions(10 studies), osteoarthritis(5 studies), nonunion or fracture(9 studies), or tendon injuries(5 studies). Significant clinical improvement with the presence of hyaline-like values and lower incidence of fibrocartilage on T2 mapping was found in patients receiving cB MA in the treatment of cartilaginous lesions. Bone consolidation and time to bone union was improved in patients receiving cB MA. Enhanced healingrates, improved quality of the repair surface on ultrasound and magnetic resonance imaging, and a decreased risk of re-rupture was demonstrated in patients receiving cB MA as an adjunctive treatment in tendon repair. CONCLUSION The current literature demonstrates the potential benefits of utilizing c BMA for the repair of cartilaginous lesions, bony defects, and tendon injuries in the clinical setting. This study also demonstrates discrepancies between the literature with regards to various methods of centrifugation, variable cell count concentrations, and lack of standardized outcome measures. Future studies should attempt to examine the integral factors necessary for tissue regeneration and renewal including stem cells, growth factors and a biologic scaffold.Arianna L Gianakos Li Sun Jay N Patel Donald M Adams Frank A Liporace 2017World Journal of Orthopedics2017,8,6:5

10Brain changes in diabetes mellitus patients withgastrointestinal symptoms显示文摘Diabetes mellitus is a common disease and its prevalence is increasing worldwide. In various studies up to 30%-70% of patients present dysfunction and complications related to the gut. To date several clinical studies have demonstrated that autonomic nervous system neuropathy and generalized neuropathy of the central nervous system(CNS) may play a major role. This systematic review provides an overview of the neurodegenerative changes that occur as a consequence of diabetes with a focus on the CNS changes and gastrointestinal(GI) dysfunction. Animal models where diabetes was induced experimentally support that the disease induces changes in CNS. Recent investigations with electroencephalography and functional brain imaging in patients with diabetes confirm these structural and functional brain changes. Encephalographic studies demonstrated that altered insular processing of sensory stimuli seems to be a key player in symptom generation. In fact one study indicated that the more GI symptoms the patients experienced, the deeper the insular electrical source was located. The electroencephalography was often used in combination with quantitative sensory testingmainly showing hyposensitivity to stimulation of GI organs. Imaging studies on patients with diabetes and GI symptoms mainly showed microstructural changes,especially in brain areas involved in visceral sensory processing. As the electrophysiological and imaging changes were associated with GI and autonomic symptoms they may represent a future therapeutic target for treating diabetics either pharmacologically or with neuromodulation.Anne M Drewes Eirik Søfteland Georg Dimcevski Adam D Farmer Christina Brock Jens B Frøkjær Klaus Krogh Asbjørn M Drewes 2016World Journal of Diabetes2016,7,2:4

13Dysregulation of mTOR activity through LKB1 inactivation显示文摘Mammalian target of rapamycin (mTOR) is aberrantly activated in many cancer types, and two rapamycin derivatives are currently approved by the Food and Drug Administration (FDA) of the United States for treating renal cell carcinoma. Mechanistically, mTOR is hyperactivated in human cancers either due to the genetic activation of its upstream activating signaling pathways or the genetic inactivation of its negative regulators. The tumor suppressor liver kinase B1 (LKB1), also known as serine/threonine kinase 11 (STK11), is involved in cell polarity, cell detachment and adhesion, tumor metastasis, and energetic stress response. A key role of LKB1 is to negatively regulate the activity of mTOR complex 1 (mTORC1). This review summarizes the molecular basis of this negative interaction and recent research progress in this area.Wei Zhou Adam I. M arcus Paula M. Vertino 2013Chinese Journal of Cancer2013,32,8:4
