2颅底骨折患者预防性使用抗生素预防脑膜炎的系统评价(英文)显示文摘目的 评价颅底骨折患者预防性使用抗生素预防脑膜炎的效果。方法 检索Cochrane临床对照试验资料库(CENTRAL)(Cochrane图书馆2005年第3期)、MEDLINE(1966~2005.09)、EMBASE(1974~2005.06)和LILACS(1982~2005.09)。电子检索美国神经外科医师协会会议记录(1997~2005.09),手工检索神经外科学会欧洲联合会会议记录摘要(1995,1999,2003)。收集比较抗生素与安慰剂或空白对照的随机对照试验。同时对检出的非随机对照试验单独进行Meta分析以比较结果。至少由两名研究者独立评价每项试验的质量并提取数据。采用RevMan4.2软件进行Meta分析。结果 纳入的5个随机对照试验和17个非随机对照试验比较了颅底骨折患者使用不同类型的预防性抗生素与安慰刹或空白对照的效果。但多数试验对方法学细节描述不充分。所有试验均将脑膜炎纳入其主要结局。共评价了符合Meta分析纳入标准的四个随机对照试验,共包括208例受试者。在降低脑膜炎的发生率、全因病死率、脑膜炎病死率和需要手术干预的脑脊液漏的发生率等方面,预防性抗生素组与对照组无显著差异。对伴或不伴脑脊液漏的患者进行亚组分析以评价其主要结局,并对所有检出的非随机对照试验(共包括2168例受试者)进行Meta分析,得出的结果与随机数据一致。 结论 现有的随机对照试验证据并不支持对颅底骨折患者预防性使用抗生素,无论其有无脑脊液漏的迹象。在更多的研究完成之前,尚无法确定颅底骨折患者使用抗生素的效果,因为迄今发表的研究均存在偏倚,尚需更多设计完善的大样本随机对照试验。Ratilal B Costa J Sampaio C 陈耀龙(译) 刁骧(审校) 2006中国循证医学杂志2006,6,8:7
3Repurposing metformin for the treatment of gastrointestinal cancer显示文摘Diabetes mellitus type 2 and cancer share many risk factors.The pleiotropic insulin-dependent and insulin-independent effects of metformin might inhibit pathways that are frequently amplified in neoplastic tissue.Particularly,modulation of inflammation,metabolism,and cell cycle arrest are potential therapeutic cancer targets utilized by metformin to boost the anti-cancer effects of chemotherapy.Studies in vitro and in vivo models have demonstrated the potential of metformin as a chemo-and radiosensitizer,besides its chemopreventive and direct therapeutic activity in digestive system(DS)tumors.Hence,these aspects have been considered in many cancer clinical trials.Case-control and cohort studies and associated meta-analyses have evaluated DS cancer risk and metformin usage,especially in colorectal cancer,pancreatic cancer,and hepatocellular carcinoma.Most clinical studies have demonstrated the protective role of metformin in the risk for DS cancers and survival rates.On the other hand,the ability of metformin to enhance the actions of chemotherapy for gastric and biliary cancers is yet to be investigated.This article reviews the current findings on the anti-cancer mechanisms of metformin and its apparatus from pre-clinical and ongoing studies in DS malignancies.Ademar Dantas Cunha Júnior Arinilda Campos Bragagnoli Felipe Osório Costa JoséBarreto Campello Carvalheira 2021World Journal of Gastroenterology2021,27,17:5
4Three-dimensional imaging of the uterus:The value of the coronal plane显示文摘Advent in three-dimensional(3D) imaging technology has seen 3D ultrasound establish itself as a useful adjunct complementary to traditional two-dimensional imaging of the female pelvis. This advantage largely arises from its ability to reconstruct the coronal plane of the uterus, which allows further delineation of many gynecological disorders. 3D imaging of the uterus is now the preferred imaging modality for assessing congenital uterine anomalies and intrauterine device localization. Newer indications include the diagnosis of adenomyosis. It can also add invaluable information to delineate other endometrial and myometrial pathology such as fibroids and endometrial polyps.Lufee Wong Nikki White Jayshree Ramkrishna Edward Araujo Júnior Simon Meagher Fabricio Da Silva Costa 2015World Journal of Radiology2015,7,12:3
5How to manage inflammatory bowel disease during the COVID-19 pandemic:A guide for the practicing clinician显示文摘Managing inflammatory bowel disease(IBD)during the coronavirus disease 2019(COVID-19)pandemic has been a challenge faced by clinicians and their patients,especially concerning whether to proceed with biologics and immunosuppressive agents in the background of a global outbreak of a highly contagious new coronavirus(severe acute respiratory syndrome coronavirus 2,SARS-CoV-2).The knowledge about the impact of this virus on patients with IBD,although it is still scarce,is rapidly evolving.In particular,concerns surrounding medications’impact for IBD on the risk of acquiring SARS-CoV-2 infection or developing COVID-19,and potentially exacerbate viral replication and the COVID-19 course,are a current thinking of both practicing clinicians and providers caring for patients with IBD.Managing patients with IBD infected with SARS-CoV-2 depends on both the clinical activity of the IBD and the occasional development and severity of COVID-19.In this review,we summarize the current data regarding gastrointestinal involvement by SARS-CoV-2 and pharmacologic and surgical management for IBD concerning this infection,and the COVID-19 impact on both the patient's psychological functioning and endoscopy services,and we concisely summarize the telemedicine roles during the COVID-19 pandemic.Júlio Maria Fonseca Chebli Natália Sousa Freitas Queiroz Adérson Omar Mourão Cintra Damião Liliana Andrade Chebli Márcia Henriques de Magalhães Costa Rogério Serafim Parra 2021World Journal of Gastroenterology2021,27,11:2
6Serum vitamin D content is associated with semen|parameters and serum testosterone levels in men显示文摘The present study aimed to evaluate the influence of serum vitamin D levels on semen quality and testosterone levels.This is a crosssectional study conducted at Androscience,Science and Innovation Center in Andrology and High-Complex Clinical and Andrology Laboratory in Sao Paulo,Brazil,with 508 male patients,aged 18-60 years,from 2007 to 2017.Seminal parameters and serum sexual hormones were correlated with serum vitamin D concentrations in 260 men selected by strict selection criteria.Patients were divided into normozoospermic group(NZG,n=124)and a group with seminal abnormalities(SAG,n=136).Evaluation included complete physical examination,past medical history,habits and lifestyle factors,two complete seminal analysis with sperm functional tests,serum levels of 25-hydroxy-vitamin D_(3)(25(OH)VD_(3)),total and free testosterone,luteinizing hormone(LH),follicle-stimulating hormone(FSH),sex hormone-binding globulin(SHBG),total cholesterol,homeostatic model assessment of insulin resistance(HOMA-IR)index,and karyotype.The mean concentration of 25(OH)VD_(3)was significantly lower in the SAG(P<0.001)and positively correlated with all baseline seminal parameters and total testosterone levels.In addition,serum vitamin D_(3)concentration was found to be positively correlated with sperm concentration(β=2.103;P<0.001),total number of spermatozoa with progressive motility(β=2.069;P=0.003),total number of motile spermatozoa(β=2.571;P=0.015),and strict morphology(β=0.056;P=0.006),regardless of other variables.This is the first comparative study to address the issue of serum vitamin D_(3)content between normozoospermic patients and those with sperm abnormalities.It clearly demonstrates a direct and positive relationship between serum vitamin D level and overall semen quality,male reproductive potential,and testosterone levels.Inari M Ciccone Elaine MF Costa Juliana R Pariz Thiago A Teixeira Joel R Drevet Parviz Gharagozloo Robert J Aitken Jorge Hallak 2021Asian Journal of Andrology2021,23,1:2
7Resveratrol attenuates metabolic,sperm,and testicular changes in adult Wistar rats fed a diet rich in lipids and simple carbohydrates显示文摘High-fat diets affect male reproduction and sexual function.Therefore,we evaluated the effects of prolonged resveratrol administration on the metabolic,sperm,and testicular parameters of rats fed a cafeteria diet.Male Wistar rats were divided at weaning into control(Cv n=20)and cafeteria(CAF,n=16)groups.At 3 months,half of them were given daily supplementations of resveratrol(C-R,n=10;CAF-R,n=8)at a dosage of 30 mg kg-1 body mass for 2 months.Animals were killed at 5 months of age,and blood,spermatozoa,and testes were collected for further analysis.Data were analyzed by one-way ANOVA,and P<0.05 was considered statistically significant.The CAF diet promoted hyperglycemia(P<0.0001),and treatment with resveratrol reversed this condition(P<0.0001).The CAF diet reduced sperm viability and motility,while resveratrol improved these parameters(F<0.05).Regarding testicular morphology,the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group(P=0.0007).Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group.However,the CAF-R showed an increase in cell proliferation rate compared with that of the untreated CAF group(P=0.0024).Although it did not modify body mass,the consumption of a CAF diet promoted hyperglycemia,adverse testicular morphology remodeling,and abnormal sperm,which were attenuated by treatment with resveratrol,thus suggesting a protective effect of this antioxidant on spermatogenesis.Fabiana A de Oliveira Waldemar S Costa Francisco J B Sampaio Bianca M Gregorio 2019Asian Journal of Andrology2019,21,2:2
8Non-pharmacological management of pediatric functional abdominal pain disorders:Current evidence and future perspectives显示文摘Functional abdominal pain disorders(FAPDs) are an important and prevalent cause of functional gastrointestinal disorders among children, encompassing the diagnoses of functional dyspepsia, irritable bowel syndrome, abdominal migraine, and the one not previously present in Rome Ⅲ, functional abdominal pain not otherwise specified. In the absence of sufficiently effective and safe pharmacological treatments for this public problem, non-pharmacological therapies emerge as a viable means of treating these patients, avoiding not only possible side effects, but also unnecessary prescription, since many of the pharmacological treatments prescribed do not have good efficacy when compared to placebo. Thus, the present study provides a review of current and relevant evidence on non-pharmacological management of FAPDs, covering the most commonly indicated treatments, from cognitive behavioral therapy to meditation, acupuncture, yoga, massage, spinal manipulation, moxibustion, and physical activities. In addition, this article also analyzes the quality of publications in the area, assessing whether it is possible to state if non-pharmacological therapies are viable, safe, and sufficiently well-based for an appropriate and effective prescription of these treatments. Finally, it is possible to observe an increase not only in the number of publications on the non-pharmacological treatments for FAPDs in recent years, but also an increase in the quality of these publications. Finally, the sample selection of satisfactory age groups in these studies enables the formulation of specific guidelines for this age group, thus avoiding the need for adaptation of prescriptions initially made for adults, but for children use.Maria Luísa Cordeiro Santos Ronaldo Teixeira da Silva Júnior Breno Bittencourt de Brito Filipe Antônio França da Silva Hanna Santos Marques Vinícius Lima de SouzaGonçalves Talita Costa dos Santos Carolina Ladeia Cirne Natália Oliveira e Silva Márcio Vasconcelos Oliveira Fabrício Freire de Melo 2022World Journal of Clinical Pediatrics2022,11,2:2

12Exogenous cytokinin application to Actinidia chinensis var. deliciosa ‘Hayward’ fruit promotes fruit expansion through water uptake显示文摘Exogenous application of a cytokinin-like compound forchlorfenuron(CPPU)can promote fruit growth,although often at the expense of dry matter(DM),an important indicator of fruit quality.Actinidia chinensis var.deliciosa‘Hayward’fruit are very responsive to CPPU treatments,but the mechanism underlying the significant fruit weight increase and associated decrease in DM is unclear.In this study,we hypothesised that CPPU-enhanced growth increases fruit carbohydrate demand,but limited carbohydrate supply resulted in decreased fruit DM.During fruit development,CPPU effects on physical parameters,metabolites,osmotic pressure and transcriptional changes were assessed under conditions of both standard and a high carbohydrate supply.We showed that CPPU increased fruit fresh weight but the dramatic DM decrease was not carbohydrate limited.Enhanced glucose and fructose concentrations contributed to an increase in soluble carbohydrate osmotic pressure,which was correlated with increased water accumulation in CPPU-treated fruit and up-regulation of water channel aquaporin gene PIP2.4 at 49 days after anthesis.Transcipt analysis suggested that the molecular mechanism contributing to increased glucose and fructose concentrations was altered by carbohydrate supply.At standard carbohydrate supply,the early glucose increase in CPPU fruit was associated with reduced starch synthesis and increased starch degradation.When carbohydrate supply was high,the early glucose increase in CPPU fruit was associated with a general decrease in starch synthesis but up-regulation of vacuolar invertase and fructokinase genes.We conclude that CPPU affected fruit expansion by increasing the osmotically-driven water uptake and its effect was not carbohydrate supply-limited.Simona Nardozza Helen L Boldingh Mark W Wohlers Andrew P Gleave Zhiwei Luo Guglielmo Costa Elspeth A MacRae Michael J Clearwater Annette C Richardson 2017Horticulture Research2017,4,1:2
13Energetic-protein supplementation in the last 60 days of gestation improves performance of beef cows grazing tropical pastures显示文摘Background: Nutrition is one of the most important factors that affect animal performance, and it therefore also impacts on financial results in beef systems. In this way, finding the best strategy for feeding supplements is of paramount importance. Aiming to evaluate the effect of supplement feeding strategies for beef cows in the last third of gestation, two experiments were conducted. In Experiment 1, 35 pregnant Nellore cows were assigned to a completely randomized design with four treatments: control, which received no supplement; supplementation for the last 30 d of gestation(30-d; 3.0 kg/d); supplementation for the last 60 d of gestation(60-d; 1.5 kg/d); or supplementation for the last 90 d of gestation(90-d; 1.0 kg/d). All supplemented treatments received the same total amount of supplement throughout the experiment: 90 kg(20% of crude protein). A second experiment(Experiment 2) was delineated to evaluate the effects of the amounts offered in Experiment 1 on intake and metabolism. Four multiparous pregnant Nellore cows were assigned to a 4 × 4 Latin square design, with periods of15 d each.Results: There was a linear effect of the number of days of supplementation on calving body weight(BW; P < 0.05)and a quadratic effect on BW change from parturition to d 31 post-calving(P < 0.05), with cows on the 60-d strategy losing less BW post-calving. No difference was found in offspring birth BW(P > 0.10). A significant linear effect on interval from parturition to conception(P < 0.05) was observed, with the highest calving to conception interval being observed in the 90-d strategy. The level of supplementation did not affect forage intake or neutral detergent fiber digestibility(P > 0.10). Nitrogen excreted through urine tended to increase linearly with the level of supplementation(P < 0.10).Conclusion: Providing 1.5 kg of supplement during the last 60 d of gestation improves cow performance after calving, reducing the magnitude of BW lost, and reduces the number of days from calving to re-conception in the following breeding season compared to the usually recommended period of supplementation of 90 d pre-partum.Aline Gomes da Silva Mário Fonseca Paulino Edenio Detmann Henrique Jorge Fernandes Lincoln da Silva Amorim Román Enrique Maza Ortega Victor Valério de Carvalho Josilaine Aparecida da Costa Lima Felipe Henrique de Moura Mariana Benevides Monteiro Jéssika Almeida Bitencourt 2018Journal of Animal Science and Biotechnology2018,9,1:2
