1儿童期应用吸入性糖皮质激素治疗对成年身高的影响显示文摘背景在青春期前儿童中,应用吸入性糖皮质激素治疗持续性哮喘可引起生长速度暂时减慢。目前认为开始吸入性糖皮质激素治疗后1~4年所致的身高降低不会降低成年后所达到的身高。方法在儿童哮喘管理计划(试验)的1 041名受试者中,我们测量了943名(90.6%)受试者的成年身高,测量成年身高时的平均年龄为(24.9±2.7)岁。从5~13岁时开始,受试者被随机分配接受每日布地奈德400μg、奈多罗米16 mg或者安慰剂治疗4~6年。我们采用对(受试者在)试验入选时人口学特性、哮喘特点以及身高进行校正的多因素线性回归方法,计算了每个治疗组的成年身高(分别)与安慰剂组相比的差异。结果布地奈德组成年平均身高较安慰剂组低1.2 cm〔95%CI(-1.9,-0.5)〕,奈多罗米组成年平均身高较安慰剂组低0.2cm〔95%CI(-0.9,0.5),P=0.61〕。最初2年内吸入性糖皮质激素的日剂量较大,与成年身高较低相关(剂量每增大1 mg/kg体质量,身高就降低0.1 cm,P=0.007)。布地奈德组与安慰剂组相比成年身高降低与治疗了2年后的身高降低情况相似〔-1.3 cm,95%CI(-1.7,-0.9)〕。在最初的2年内,布地奈德组的生长速度减慢主要发生在青春期前的受试者中。结论青春期前儿童中最初出现的、与应用吸入性糖皮质激素治疗相关的身高降低在成年时仍持续存在,不过身高的降低不是进行性的,也不具有累积性。Kelly HW Sternberg AL Lescher R 2012中国全科医学2012,15,36:9

3Vascular depression for radiology: A review of the construct,methodology,and diagnosis显示文摘Vascular depression(VD)as defined by magnetic resonance imaging(MRI)has been proposed as a unique subtype of late-life depression.The VD hypothesis posits that cerebrovascular disease,as characterized by the presence of MRIdefined white matter hyperintensities,contributes to and increases the risk for depression in older adults.VD is also accompanied by cognitive impairment and poor antidepressant treatment response.The VD diagnosis relies on MRI findings and yet this clinical entity is largely unfamiliar to neuroradiologists and is rarely,if ever,discussed in radiology journals.The primary purpose of this review is to introduce the MRI-defined VD construct to the neuroradiology community.Case reports are highlighted in order to illustrate the profile of VD in terms of radiological,clinical,and neuropsychological findings.A secondary purpose is to elucidate and elaborate on the measurement of cerebrovascular disease through visual rating scales and semi-and fully-automated volumetric methods.These methods are crucial for determining whether lesion burden or lesion severity is the dominant pathological contributor to VD.Additionally,these rating methods have implications for the growing field of computer assisted diagnosis.Since VD has been found to have a profile that is distinct from other types of late-life depression,neuroradiologists,in conjunction with psychiatrists and psychologists,should consider VD in diagnosis and treatment planning.Sara N Rushia Al Amira Safa Shehab Jeffrey N Motter Dakota A Egglefield Sophie Schiff Joel R Sneed Ernst Garcon 2020World Journal of Radiology2020,12,5:5
4Transradial approach for acute stroke intervention: technical procedure and clinical outcomes显示文摘background and purpose Radial artery catheterisation is an alternate route of access that has recently started to gain more widespread use for neuroendovascular procedures,including acute stroke intervention.In this small case series,we present our institution’s outcomes in patients undergoing acute stroke interventions via transradial access.Materials and methods We present a retrospective study of 15 patients who underwent acute stroke intervention via radial artery access.We analyse these patients’periprocedural and clinical outcomes after undergoing mechanical thrombectomy.results A total of 15 consecutive patients were included in the study(9 males and 6 females),and all patients were able to successfully undergo mechanical thrombectomy via radial artery access.The mean time of arterial puncture to reperfusion was 50±28 min(range:15-104).A TICI 2b/3 revascularisation was achieved in 13/15 patients(87%);a TICI 1 and TICI 2a outcome was achieved on the other two patients.One patient incurred an iatrogenic vessel dissection during the procedure.Eight of out 15 patients(53%)had favourable mRS(0-3)at the time of discharge from the hospital.Conclusion Radial artery catheterisation is technically feasible for performing acute stroke interventions with favourable time to revascularisation and good overall clinical outcomes.Omaditya Khanna Nikolaos Mouchtouris Ahmad Sweid Nohra Chalouhi Ritam Ghosh Fadi Al Saiegh Michael R Gooch Stavropoula Tjoumakaris Robert H Rosenwasser Victor Romo Pascal Jabbour 2020Stroke & Vascular Neurology2020,5,1:4
5Urbanization reduces resource use efficiency of phytoplankton community by altering the environment and decreasing biodiversity显示文摘Urbanization often exerts multiple effects on aquatic and terrestrial organisms,including changes in biodiversity,species composition and ecosystem functions.However,the impacts of urbanization on river phytoplankton in subtropical urbanizing watersheds remain largely unknown.Here,we explored the effects of urbanization on phytoplankton community structure(i.e.,biomass,community composition and diversity)and function(i.e.,resource use efficiency)in a subtropical river at watershed scale in southeast China over 6 years.A total of 318 phytoplankton species belonging into 120 genera and 7 phyla were identified from 108 samples.Bacillariophyta biomass showed an increasing trend with increasing urbanization level.The phytoplankton community shifted from Chlorophyta dominance in rural upstream waters to Bacillariophyta dominance in urbanized downstream waters.Furthermore,phytoplankton diversity and resource use efficiency(RUE=phytoplankton biomass/total phosphorus)were significantly decreased with increasing urbanization level from upstream to downstream.Phytoplankton RUE exhibited a significant positive correlation with species richness,but a negative correlation with phytoplankton evenness.The variation in environmental factors(turbidity,total nitrogen,NH_(4)^(+)-N,total phosphorus,PO_(4)^(3-)-P and percentage urbanized area)was significantly correlated with phytoplankton diversity and RUE.Overall,our results revealed the influence of urbanization on phytoplankton community structure and ecosystem function was due to its altering the environmental conditions.Therefore,human-driven urbanization may play crucial roles in shaping the structure and function of phytoplankton communities in subtropical rivers,and the mechanism of this process can provide important information for freshwater sustainable uses,watershed management and conservation.Yigang Yang Huihuang Chen Mamun Abdullah Al Jean Claude Ndayishimiye Jun R Yang Alain Isabwe Anqi Luo Jun Yang 2022Journal of Environmental Sciences2022,34,2:4
6Treatment of hepatitis C virus genotype 4 with peginterferon alfa-2a: Impact of bilharziasis and fibrosis stage显示文摘AIM: To evaluate pegylated interferon alpha2a (PegIFN- α2a) in Egyptian patients with HCV genotype 4, and the impact of pretreatment viral load, co-existent bilharziasis and histological liver changes on response rate. METHODS: A total of 73 na?ve patients (61 with history of bilharziasis) with compensated chronic HCV genotype 4 were enrolled into: group A (38 patients) who received 180 mg PegIFN-alpha2a subcutaneously once weekly for a year and group B (35 patients) received IFN alpha-2a 3 MU 3 times weekly. Ribavirin was added to each regimen at a dose of 1200 mg. Patients were followed for 72 wk and sustained response was assessed. RESULTS: Significant improvement in both end of treatment response (ETR) (P < 0.002) and sustained response (SR) (P < 0.05) was noted with pegylated interferon, where ETR was achieved in 29 (76.3%) and 14 patients (40%) in both groups respectively, and 25 patients in group A (65.8%) and 9 (25.7%) in group B could retain negative viraemia by the end of follow up period. Sustained virological response (SVR) showed a significant negative correlation with age and positive correlation with pretreatment inflammation in patients receiving PegIFN. Viral clearance after 3 mo of therapy was associated with high incidence of ETR and SR (P < 0.001), but without significant difference between both forms of interferon. Significant improvement in response was achieved in patients with high grade fibrosis (grade 3 and 4) with PegIFN-α2a, where SR was seen in 5 out of 13 patients in group A, but none in group B. There was no significant difference in response betweenbilharzial and non-bilharzial patients in both groups. In terms of safety and tolerability, neutropenia was the predominant side effect; both drugs were comparable. CONCLUSION: PegIFN-α2a combined with ribavirin results in improvement in sustained response in HCV genotype 4, irrespective of history of bilharzial infestation.MF Derbala SR Al Kaabi NZ El Dweik F Pasic MT Butt R Yakoob A Al-Marri AM Amer N Morad A Bener 2006World Journal of Gastroenterology2006,12,35:3
7Appropriateness of systemic treatments in unresectable metastatic well-differentiated pancreatic neuroendocrine tumors显示文摘AIM:To evaluate systemic treatment choices in unresectable metastatic well-differentiated pancreatic neuroendocrine tumors(PNETs)and provide consensus treatment recommendations.METHODS:Systemic treatment options for pancreatic neuroendocrine tumors have expanded in recent years to include somatostatin analogs,angiogenesis inhibitors,inhibitors of mammalian target of rapamycinand cytotoxic agents.At this time,there is little data to guide treatment selection and sequence.We therefore assembled a panel of expert physicians to evaluate systemic treatment choices and provide consensus treatment recommendations.Treatment appropriateness ratings were collected using the RAND/UCLA modified Delphi process.After studying the literature,a multidisciplinary panel of 10 physicians assessed the appropriateness of various medical treatment scenarios on a 1-9 scale.Ratings were done both before and after an extended discussion of the evidence.Quantitative measurements of agreement were made and consensus statements developed from the second round ratings.RESULTS:Specialties represented were medical and surgical oncology,interventional radiology,and gastroenterology.Panelists had practiced for a mean of15.5 years(range:6-33).Among 202 rated scenarios,disagreement decreased from 13.2%(26 scenarios)before the face-to-face discussion of evidence to 1%(2)after.In the final ratings,46.5%(94 scenarios)were rated inappropriate,21.8%(44)were uncertain,and30.7%(62)were appropriate.Consensus statements from the scenarios included:(1)it is appropriate to use somatostatin analogs as first line therapy in patients with hormonally functional tumors and may be appropriate in patients who are asymptomatic;(2)it is appropriate to use everolimus,sunitinib,or cytotoxic chemotherapy therapy as first line therapy in patients with symptomatic or progressive tumors;and(3)beyond first line,these same agents can be used.In patients with uncontrolled secretory symptoms,octreotide LAR doses can be titrated up to 60 mg every4 wk or up to 40 mg every 3 or 4 wk.CONCLUSION:Using the Delphi process allowed physician experts to systematically obtain a consensus on the appropriateness of a variety of medical therapies in patients with PNETs.Jonathan R Strosberg George A Fisher Al B Benson Lowell B Anthony Bulent Arslan John F Gibbs Edward Greeno Renuka V Iyer Michelle K Kim William J Maples Philip A Philip Edward M Wolin Dasha Cherepanov Michael S Broder 2015World Journal of Gastroenterology2015,21,8:2

10Micronucleus analysis in patients with colorectal adenocarcinoma and colorectal polyps显示文摘AIM:To determine,by counting micronucleus (MN) frequencies,whether chromosomal or DNA damage have an effect on the pathogenesis of early colorectal adenocarcinoma (CRC). METHODS:We analyzed MN frequencies in 21 patients with CRC,24 patients with colon polyps [10 neoplastic polyps (NP) and 14 non-neoplastic polyps (NNP)] and 20 normal controls. RESULTS:MN frequency was significantly increased in CRC patients and in NP patients compared with controls (3.72 ± 1.34,3.58 ± 1.21 vs 1.97 ± 0.81,P < 0.001). However,there was no difference in the MN frequency between CRC patients and NP patients (P > 0.05). Similarly,there was no difference in the MN frequency between NNP patients (2.06 ± 0.85) and controls (P > 0.05). CONCLUSION:Our results suggest increased chromosome/DNA instabilities may be associated with the pathogenesis of early CRC.Ali Karaman Dogan Nas■r Binici Mehmet E■ref Kabalar Züleyha ■al■ku■u 2008World Journal of Gastroenterology2008,14,44:2
