AIM: To combine the benefits of a new thin flexible scope with elimination of excessive looping through the use of an overtube. METHODS: Three separate retrospective series. Series 1: 25 consecutive male patients undergoing unsedated colonoscopy using the new device at a Veteran's hospital in the United States. Series 2: 75 male patients undergoing routine colonoscopy using an adult colonoscope, pediatric colonoscope, or the new device. Series 3: 35 patients who had incomplete colonoscopies using standard instruments. RESULTS: Complete colonoscopy was achieved in all 25 patients in the unsedated series with a median cecal intubation time of 6 min and a median maximal pain score of 3 on a 0-10 scale. In the 75 routine cases, there was significantly less pain with the thin scope compared to standard adult and pediatric colonoscopes. Of the 35 patients in the previously incomplete colonoscopy series, 33 were completed with the new system. CONCLUSION: Small caliber overtube-assisted colonoscopy is less painful than colonoscopy with standard adult and pediatric colonoscopes. Male patients could undergo unsedated colonoscopy with the new system with relatively little pain. The new device is also useful for most patients in whom colonoscopy cannot be completed with standard instruments.

This paper presents a new yaw stability controller for a rear double-driven electric vehicle. A linear parameter varying(LPV) model of the vehicle is formulated using longitudinal speed measurement and tire cornering stiffness estimation. The LPV model is then utilized to design a gain-scheduled H∞controller with guaranteed stability. Results from simulations, performed with Car Sim, show that the new controller improves the vehicle performance and handling even in extreme maneuvers and that it is robust to model parameter uncertainties.

AIM:To review our experience performing polypectomy in anticoagulated patients without interruption of ***: Retrospective chart review at the Veterans Affairs Palo Alto Health Care System. Two hundred and twenty five polypectomies were performed in 123 patients. Patients followed a standardized protocol that included stopping warfarin for 36 h to avoid supratherapeutic anticoagulation from the bowel preparation. Patients with lesions larger than 1 cm were generally rescheduled for polypectomy off warfarin. Endoscopic clips were routinely applied prophylactically. RESULTS: One patient (0.8%, 95% CI: 0.1%-4.5%) developed major post-polypectomy bleeding that required transfusion. Two others (1.6%, 95% CI: 0.5%-5.7%) had self-limited hematochezia at home and did not seek medical attention. The average polyp size was 5.1 ± 2.2 mm. CONCLUSION: Polypectomy can be performed in therapeutically anticoagulated patients with lesions up to 1 cm in size with an acceptable bleeding rate.

AIM: To evaluate the efficacy of intravitreal injection of conbercept(IVC) and ranibizumab(IVR) in patients with diabetic macular ***: Reviewers have searched 12 databases, including PubMed, Medline, EMBASE, Web of Science, Springer, ScienceDirect, OVID, Cochrane Library, Clinical ***, cqVIP, WanFangdata and China National Knowledge Infrastructure(CNKI), up to December 28, 2018. Rev Man 5.3(Cochrane Library Software, Oxford, UK) was employed for statistical analysis. Fixed and random effects models were applied to assess heterogeneity. Odds ratio(OR) was applied for dichotomous variables;weighted mean difference(WMD) was applied for continuous variables. The confidence interval(CI) was set at 95%. Central macular thickness(CMT) and best-corrected visual acuity(BCVA) were employed to analyze the improvement of DME patients. Inclusion criteria for picking out studies were retrospective studies and randomized controlled trials(RCTs) that compared IVC and IVR for the treatment of diabetic macular ***: Four retrospective studies and five RCTs were included with a total of 609 patients. No statistically significant difference was observed in mean CMT and mean BCVA in the baseline parameters [BCVA(WMD:-0.48;95%CI:-1.06 to 0.10;P=0.1), CMT(WMD:-0.83;95%CI:-15.15 to 13.49;P=0.91). No significant difference was found in the improvement of BCVA and adverse event(AE) in IVC group, compared with IVR group after treatment of loading dosage [the 1 st month BCVA(WMD: 0.01;95%CI:-0.26 to 0.27;P=0.96), the 3 rd month BCVA(WMD:-0.04;95%CI:-0.14 to 0.06;P=0.46);the 6 th month BCVA(WMD:-0.24;95%CI:-1.62 to 1.14;P=0.73)], AE(OR: 0.84;95%CI: 0.38 to 1.84;P=0.66)]. A slight difference was found in the effectiveness rate(OR: 1.70;95%CI: 0.97 to 2.96;P=0.06), There were statistically significant differences between IVC and IVR treatment in terms of CMT (1 st month CMT(WMD:-19.88;95%CI:-27.94 to-11.82;P<0.001), 3 rd month CMT(WMD:-23.31;95%CI:-43.30 to-3.33;P=0.02),

Alzheimer's disease(AD)is known to be a progressive neurodegenerative illness that attacks the brain,causing alterations in synaptic transmission,dystrophic neurites,and neuronal death brought on by the accumulation of neurofibrillary tangles in neuronsand neuritic amyloidbeta(Aβ)plaques in the extracellular space resulting in brain shrinkage and misshapen architecture[1].
