Modified internal limiting membrane flap technique for large chronic macular hole: Two case reports

Rationale:Internal limiting membrane (ILM) peeling and gas tamponade are the standardized treatments for macular holes (MHs). However, the close rate is low, and postoperative vision is unsatisfactory in large, chronic MHs. Currently, various modifications of the ILM flap techniques are being gradually applied for large MHs in the hope of obtaining better postoperative effects. This study described 2 successful cases achieved by “Sandwich-type” modified ILM flap covering technique in patients with large, chronic MHs.Patient concerns:A 62-year-old woman presented with decreased vision and visual distortion of the left eye for 18 months. Optical coherence tomography (OCT) showed the absence of full-thickness neuroepithelial tissue in the central fovea, with a minimum MH diameter of 742 μm and a base diameter of 1630 μm. A 57-year-old man experienced decreased visual acuity for 8 months. OCT showed the absence of full-thickness neuroepithelial tissue in the central fovea, with a minimum MH diameter of 713 μm and a basal diameter of 939 μm.Diagnoses:Two patients were diagnosed with large, chronic MH based on the OCT results and duration of the hole.Interventions:The 2 patients were treated with the “sandwich-type” modified ILM flap covering technique.Outcomes:Large, chronic MH closure was observed using SD-OCT, and the BCVA improved. The patients were very satisfied with the postoperative results.Lessons:“Sandwich-type” modified ILM flap covering technique may be a safe, effective way for large, chronic MH.     

Arthroscopy versus nonoperative treatment of symptomatic femoroacetabular impingement syndrome: A systematic review and meta-analysis

Background:Presently, hip arthroscopy is a widely adopted surgical intervention for the treatment of femoroacetabular impingement (FAI). However, there is insufficient evidence regarding which between arthroscopy and nonoperative treatment is more optimal for symptomatic FAI.Methods:MEDLINE, Embase, Web of Science, and the Cochrane Library were systematically searched for studies that compared arthroscopy and nonoperative interventions for FAI treatment from inception to August 4, 2020. We included studies that directly compared surgical and nonsurgical treatment for symptomatic FAI and excluded those that did not use arthroscopic treatment as a surgical technique and studies performed on patients with concomitant diagnoses instead of pure FAI. We compared the following clinical outcome scores at 6 and 12 months of follow-up: International Hip Outcome Tool 33 (iHOT-33), hip outcome score (HOS), EuroQol-visual analog scale (EQ-VAS), modified Harris hip score (mHHS), and nonarthritic hip score (NAHS).Results:Five studies totaling 838 patients were included in the qualitative and quantitative synthesis; 382 patients underwent hip arthroscopy, and 456 patients were treated by nonoperative interventions. At 6 months of follow-up, there were no statistically significant differences in iHOT-33 ratings (mean difference [MD] = 7.92, P = .15), HOS (MD of HOS-ADL = 5.15, P = .26 and MD of HOS-Sports = 2.65, P = .79, respectively), and EQ-VAS (MD = 1.22, P = .76) between the 2 treatment strategies. At 12 months of follow-up, the arthroscopy group had a greater mean improvement in iHOT-33 score than the conservative treatment group (MD = 8.42, P = .002), but there was no difference between the groups in terms of mHHS rating (MD = −0.24, P = .83) and NAHS (MD = −2.08, P = .09).Conclusion:Despite arthroscopy being associated with significantly superior iHOT-33 scores after 12 months of follow-up, we were unable to discern the difference between the treatment strategies using other scoring methods, such as HOS, EQ-VAS, mHHS, and NAHS. Further studies will be needed to conclusively determine if 1 strategy is superior to the other for treating FAI.     

Coracoclavicular Ligament Reconstruction: A Systematic Review and a Biomechanical Study of a Triple Endobutton Technique

Operative intervention is recommended for complete acromioclavicular (AC) joint dislocation to restore AC stability, but the best operative technique is still controversial.Twelve fresh-frozen male cadaveric shoulders (average age, 62.8 ± 7.8 years) were equally divided into endobutton versus the modified Weaver-Dunn groups. Each potted scapula and clavicle was fixed in a custom made jig to allow translation and load to failure testing using a Zwick BZ2.5/TS1S material testing machine (Zwick/Roell Co, Germany). A systematic review of 21 studies evaluating reconstructive methods for coracoclavicular or AC joints using a cadaveric model was also performed.From our biomechanical study, after ligament reconstruction, the triple endobutton technique demonstrated superior, anterior, and posterior displacements similar to that of the intact state (P > 0.05). In the modified Weaver-Dunn reconstruction group, however, there was significantly greater anterior (P < 0.001) and posterior (P = 0.003) translation after ligament reconstruction. In addition, there was no significant difference after reconstruction between failure load of the triple endobutton group and that of the intact state (686.88 vs 684.9 N, P > 0.05), whereas the failure load after the modified Weaver-Dunn reconstruction was decreased compared with the intact state (171.64 vs 640.86 N, P < 0.001).From our systematic review of 21 studies, which involved comparison of the modified Weaver-Dunn technique with other methods, the majority showed that the modified Weaver-Dunn procedure had significantly (P < .05) greater laxity than other methods including the endobutton technique.The triple endobutton reconstruction proved superior to the modified Weaver-Dunn technique in restoration of AC joint stability and strength. Triple endobutton reconstruction of the coracoclavicular ligament is superior to the modified Weaver-Dunn reconstruction in controlling both superior and anteroposterior displacements with a failure load that approximates the intact ligament.     

Percutaneous pinning with interphalangeal joint locked in phalanx fractures: The surgical technique and the results

Background:The purpose of the study was to compare the operation time, the fracture healed time, the postoperative function recovery between the techniques that temporary locking of the interphalangeal joint and traditional manual reduction in the treatment of percutaneous pinning of the phalanx fractures.Methods:Patients with phalanx fractures from January 2015 to January 2018 who were admitted to our hospital were retrospectively reviewed. Patients received surgery with traditional manual or temporary locking of the interphalangeal joint reduction. The information of patients, including age, gender, the length of the operation, the fracture healed time, the postoperative function recovery, complication, and length of postoperative hospital stay, was collected. All of the information were evaluated and compared between the 2 groups. All of the surgery were performed by 2 experienced hand surgeons of our department. The patients in the 2 groups were followed up for an average of 6 months after surgery.Results:All patients completed the operation and were followed up completely. There was no significant difference in baseline data between the 2 groups (P > .05). The observation group who received surgery with the interphalangeal joint locked technique had significantly shorter in operative time than the control group (P < .05). And postoperative complications in the observation group were significantly less than those in the control group (P < .05). However, the postoperative functional recovery in both groups was no significant difference between the 2 groups (P > .05). And there were no significant differences in the fracture healed time and length of postoperative hospital stay between the 2 groups (P > .05).Conclusion:Both surgical techniques can enable patients to achieve good function, but the technique of interphalangeal joint locked is effective in the treatment of the phalanx fractures, as it is characterized by short operations and a quick recovery. However, this technique is only suitable for extra-articular phalanx fractures that the AO/ASIF classification of type A2.3 and less than 2 weeks, not for other phalanx fractures.     

Efficacy of sequential N-butylphthalide therapy on psychiatric and behavioral functions in acute ischemic stroke

Background:Stroke can cause physical and mental problems. This study examined how the sequential therapy of N-butylphthalide (NBP) could effectively improve physical movement, life activities, and psychological disorders in stroke patients.Methods:This double-blind, randomized controlled trial included middle-aged or elderly patients with acute ischemic stroke that had commenced within 48 hours before enrolment in the study. The experimental group was administered 100 mL NBP injections twice a day in the first 14 days, and a sequential 200 mg NBP soft capsule 3 times a day for the next 76 days. The control group was administered 100 mL NBP placebo injections twice a day in the first 14 days and 200 mg sequential NBP placebo soft capsule 3 times a day for the next 76 days. Primary outcomes were the National Institutes of Health Stroke Scale, the Barthel Index of activities of daily living, and Modified Rankin Scale which were evaluated at day 0, day 14, and month 1 or at day 14, month 3, and month 6. Secondary outcomes included the Hamilton Anxiety Scale and the Hamilton Depression Scale, all were evaluated on day 0, month 3, and month 6. Moreover, the adverse reaction of NBP or other serious adverse events were evaluated at each time.Results:Our therapy significantly increased the Barthel Index of activities of daily living scores, decreased the National Institutes of Health Stroke Scale and Modified Rankin Scale scores, and the incidence of the Hamilton Anxiety Scale and the Hamilton Depression Scale of ischemic stroke patients (P < .05).Conclusion:Our results indicated that 90 days’ sequential therapy with NBP as an additional therapy in the treatment of ischemic stroke can better improve patients’ psychological and behavioral functions without significant side effects.     

Clinical and radiological results of surgically treated patients with adolescent idiopathic scoliosis and the effects of pulmonary rehabilitation on respiration functions

Background:In the present study, we aimed to evaluate the effects of pulmonary rehabilitation on respiratory functions after the surgery on the basis of early radiological findings, pain degree, function, and satisfaction scores in operated patients with adolescent idiopathic scoliosis (AIS).Methods:Thirty patients with AIS were included in the present study, who were divided into 2 groups. Scoliosis surgery and diaphragmatic breathing and pursed lip exercises were applied in Group 1 (n = 15), whereas merely scoliosis surgery was applied in Group 2 (n = 15). Pulmonary functions, arterial blood gas analysis, Cobb and kyphosis angles, apical vertebral rotation, and apical vertebral translation were measured before and 1st and 6th months after the surgery. Using the SRS-30 test, the psychosocial statuses of the patients and their satisfaction degrees with surgery applied were measured before and after the surgery.Results:Six months after the surgery, the values of Cobb and kyphosis angles and apical vertebral rotations, and apical vertebral translation of the patients were determined to be significantly ameliorated, which is consistent with the literature. Forced vital capacity (l) and forced expiratory volume in the first second (l/s) were observed to be significantly improved in both groups after the surgery (respectively, P = .001, P = .014, P = .001, P = .005). In addition, the partial pressure of oxygen (pO₂) value was found to be significantly increased 6 months after the surgery compared with that before the surgery in Group 2 (P = .022). SRS-30 showed that most of the scores in Group 1 were dramatically increased; a significant difference between the groups was not recorded.Conclusion:Patients with AIS have been found to be satisfied with the surgery. Conversely, pulmonary rehabilitation has been shown to slightly improve the respiratory functions in the patients with AIS, 1 and 6 months after the surgery.     

LigaSure hemorrhoidectomy versus the procedure for prolapse and hemorrhoids: A meta-analysis of randomized controlled trials

Background:LigaSure hemorrhoidectomy and the procedure for prolapse and hemorrhoids (PPH) are both relatively new treatments for managing symptomatic hemorrhoids. This review aimed to evaluate and compare their short-term outcomes.Methods:We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials and the China National Knowledge Infrastructure database for randomized controlled trials comparing the LigaSure procedure and PPH published in any language from 1998 to October 2013.Results:A total of 5 studies involving 397 participants were included in this review. Pooled analysis showed that the LigaSure procedure was associated with significantly lower recurrence rate [relative risk (RR) = 0.21, 95% confidence interval (CI): 0.06 to 0.72, P = .01] and significantly shorter operating time [mean difference (MD) = −6.39, 95% CI: −7.68 to −5.10, P < .001]. The analysis showed no significant difference in postoperative pain between the two techniques (MD = 0.55, 95% CI: −0.15 to 1.25, P = .12] or in time off work or away from normal activity [standard MD = 0.13, 95% CI: −1.80 to 2.06, P = .9]. The two techniques did not show significant differences in postoperative complications or other patient-related outcomes (P > .05).Conclusions:Our review indicates that both LigaSure hemorrhoidectomy and PPH are safe alternatives for the management of hemorrhoids. Available evidence suggests that the LigaSure technique is associated with shorter operating time and lower hemorrhoid recurrence rate, but these conclusions should be further confirmed in large, multicenter randomized controlled trials with long-term follow-up.     

The prognosis of cancer patients undergoing liposomal doxorubicin-based chemotherapy: A systematic review and meta-analysis

Background:It is well known that liposome-based delivery of cytotoxic chemotherapeutics has been proposed as a putative strategy to enhance drug tolerability and efficacy compared to the conventional chemotherapy. However, its potential effect on improving prognosis remains largely unknown. The current meta-analysis is to explore the prognosis of cancer patients undergoing liposomal doxorubicin-based chemotherapy.Methods:A detailed review of English and Chinese literature was conducted up to March 21, 2020. We evaluate its possible correlations using hazard ratios (HRs) with 95% confidence intervals (CIs). The pooled data were calculated by STATA software and Review Manager 5.3 software.Results:Consequently, 26 studies including 7943 patients were satisfied in current analysis. There were no significant differences between liposomal and conventional chemotherapy in OS (HR = 0.98, 95%CI: 0.93–1.04, P = .544) and PFS (HR = 1.00, 95%CI: 0.92–1.10, P = .945). Likewise, subgroup-analysis regarding country, cancer type, and sample sizes also showed the similar results of the 2 paired groups.Conclusion:Taken together, our finding has demonstrated that there was no association of undergoing liposomal doxorubicin-based chemotherapy with cancer prognosis. However, detailed and further studies are needed to confirm our conclusion.     

Single-stage intraoperative ERCP combined with laparoscopic cholecystectomy versus preoperative ERCP Followed by laparoscopic cholecystectomy in the management of cholecystocholedocholithiasis: A meta-analysis of randomized trials

ObjectivesThe optimal treatment strategy for cholecystocholedocholithiasis is still controversial. We conducted an up-to-date meta-analysis to compare the efficacy and safety of the intra- endoscopic retrograde cholangiopancreatography (ERCP) + LC procedure with the traditional pre-ERCP +  laparoscopic cholecystectomy (LC) procedure in the management of cholecystocholedocholithiasis.MethodsWe searched the PubMed, Embase, Cochrane Library, and Web of Science databases up to September 2020. Published randomized controlled trials comparing intra-ERCP + LC and pre-ERCP + LC were considered. This meta-analysis was performed by Review Manager Version 5.3, and outcomes were documented by pooled risk ratio (RR) and mean difference (MD) with 95% confidence intervals.ResultsEight studies with a total of 977 patients were included in this meta-analysis. There was no significant difference between the two groups regarding CBD stone clearance (RR = 1.03, P = .27), postoperative papilla bleeding (RR = 0.41, P = .13), postoperative cholangitis (RR = 0.87, P = .79), and operation conversion rate (RR = 0.71, P = .26). The length of hospital stay was shorter in the intra-ERCP + LC group (MD = −2.75, P < .05), and intra-ERCP + LC was associated with lower overall morbidity (RR = 0.54, P < .05), postoperative pancreatitis (RR = 0.29, P < .05) and cannulation failure rate (RR = 0.22, P < .05).ConclusionsIntra-ERCP + LC was a safer approach for patients with cholecystocholedocholithiasis. It could facilitate intubation, shorten hospital stay, and lower postoperative complications, especially postoperative pancreatitis, and reduce stone residue and reduce the possibility of reoperation for stone removal.     

The effect of binaural beat audio on anxiety in patients undergoing fiberoptic bronchoscopy: A prospective randomized controlled trial

Background:Fiberoptic bronchoscopy is an invasive procedure known to induce anxiety in patients. Binaural beat therapy, in which sounds of different frequencies are delivered to the 2 ears to entrain the brainwaves, has been used to reduce anxiety in some operations. This study aimed to determine the anxiolytic effects of binaural beat audio in patients undergoing fiberoptic bronchoscopy.Methods:Eligible subjects were randomly assigned to receive binaural beat music, plain music, or no music. They were asked to wear earphones starting approximately 15 minutes before the bronchoscopy. The level of anxiety was measured using the State-Trait Anxiety Inventory questionnaire. Blood pressure, heart rate, and sedative drug administration were also recorded.Results:One hundred and twelve subjects were randomized into binaural beat music (n = 38), plain music (n = 38), and no music (n = 36) groups. The mean change in post-bronchoscopy State-Trait Anxiety Inventory state score in the binaural beat music, plain music, and no music group was −7.26 (P < .001), −3.92 (P = .005), and −1.12 (P = .454), respectively. The mean systolic blood pressure and diastolic blood pressure significantly decreased from baseline by −9.89 (P = .002) and −5.76 (P = .005), respectively, in the binaural group. The mean heart rate increased from baseline by 3.32 (P = .035), 5.21 (P = .038), and 3.64 (P = .149) in the binaural beat music, plain music, and no music groups, respectively.Conclusion:Binaural beat music appeared to reduce anxiety among patients undergoing fiberoptic bronchoscopy.Trial registration: TCTR, TCTR20200915002.

Percutaneous removal of common bile duct stones using a modified balloon technique

To evaluate the effectiveness of percutaneous removal of common bile duct (CBD) stones using a modified balloon technique (balloon catheter sphincteroplasty and expulsion of the stones using half-captured balloons within the sheath) in patients difficult to treat with endoscopy.Fifty patients underwent a modified balloon technique (balloon group), and 53 patients underwent CBD stone removal by the basket method (stone basket group) between 2016 and 2019. We compared the balloon and stone basket groups to evaluate the effectiveness of the modified balloon technique. Outcome variables such as demographics, technical success rates, procedural details, and complications were analyzed. Statistical analysis was performed using Student t test, Fisher exact test, or the χ² test.The technical success rate in the balloon group was 66% (33/50) in 1 session, 32% (16/50) in 2 sessions, and 2% (1/50) in 3 sessions. That of the stone basket group was 45% (24/53) in 1 session, 38% (20/53) in 2 sessions, and 17% (9/53) in 3 sessions.The total procedure time was significantly shorter in the balloon group (29.5 ± 15.1 minutes) than in the stone basket group (41.7 ± 20.2 minutes) (P < .01), whereas the number of stones was higher in the balloon group than in the stone basket group (P = .03). Maximal stone size, balloon size, pancreatitis, and hospitalization stay did not show statistical differences between the 2 groups. Most complications (9 patients, balloon group; 8 patients, stone basket group) were mild and transient. Major complications occurred in one patient in the stone basket group, who experienced hemobilia due to arterial injury caused by percutaneous transhepatic biliary drainage, which was treated by endovascular embolization without mortality.The modified balloon technique is an effective and safe treatment method for CBD stone removal in patients presenting difficulties in the endoscopic approach.     

Efficacy and safety of rt-PA intravenous thrombolysis in patients with wake-up stroke: A meta-analysis

Background: Recombinant tissue plasminogen activator (rt-PA) is one of the most effective therapies for patients with acute ischemic stroke. However, wake-up stroke (WUS) is typically excluded from intravenous thrombolytic therapy because of the unclear time of symptom onset. Therefore, we aimed to assess the efficacy and safety of rt-PA intravenous thrombolysis in patients with WUS by meta-analysis.Methods: We completed a systematic literature search of PubMed, Embase, the Cochrane Library, and SinoMed and included relevant studies of WUS patients covering rt-PA thrombolysis and nonthrombolysis (published from January 1, 2000, to February 28, 2021, with no language restrictions). The primary outcomes included safety outcomes and functional outcomes. Safety outcomes were measured according to the incidence of symptomatic intracranial hemorrhage and mortality within 90 days. The efficacy outcomes were measured based on 90-day modified Rankin Scale scores. We assessed pooled data using either a random-effects model (when P < .10, I ² > 50%) or a fixed-effects model (when P > .10, I ² < 50%).Results: A total of 913 patients from 9 studies were included in the meta-analysis. All patients had ischemic stroke confirmed by computed tomography or magnetic resonance imaging. The incidence of modified Rankin Scale 0 to 2 was significantly higher in the rt-PA thrombolysis group compared with the nonthrombolysis group. And rt-PA thrombolytic WUS patients did not differ significantly from nonthrombolytic WUS patients in terms of 90-day mortality. However, the incidence of Symptomatic intracranial hemorrhage was also significantly higher in the rt-PA thrombolysis group than that in the nonthrombolysis group.Conclusions: Patients with WUS who received rt-PA thrombolysis had a significant positive effect within 90 days. In addition, although there was no significant increase in mortality, we need to be aware of the risk of intracranial hemorrhage transformation associated with rt-PA thrombolysis despite no obvious increase in mortality. The safety of rt-PA intravenous thrombolysis should be closely monitored in patients with WUS.     

Application of digital practice to improve head movement,visual perception and activities of daily living for subacute stroke patients with unilateral spatial neglect: Preliminary results of a single-blinded,randomized controlled trial

Background:Virtual reality (VR) based digital practice is an attractive way to provide a patient engagement, motivation and adaptable environment for stroke rehabilitation. However, clinical evidence of efficacy with VR-based digital practice is very limited. In this study, we investigated the effects of VR-based digital practice program on unilateral spatial neglect (USN) rehabilitation in patients with subacute stroke.Methods:Twenty-four subacute stroke patients with USN were enrolled and randomly assigned to digital practice group (n = 12) and control group (n = 12). Patients in digital practice group received training programs with VR-based applications with leap motion environment. Control group received conventional USN specific training programs. All patients were underwent 4 week practice program (3 sessions/week, a half-hour/session). We analyzed training effects before and after training by assessing the line bisection test, Catherine Bergego Scale, modified Barthel index, Motor-Free Visual Perception Test Vertical Version (MVPT-V), and horizontal head movements (rotation degree and velocity during the VR-based applications), and compared the results between the two groups.Results:Compared to control group, digital practice group showed significantly greater improvements in the line bisection test (P = .020), and visual perceptual tasks (MVPT-V, responded more on left visual task, P = .024; correctly respond more on both left and right visual tasks, P = .024 and P = .014, respectively; and faster response time, P = .014). Additionally, horizontal head movement of rotation degree and velocity during the VR based practice in the digital practice group were significantly increased more than control group (P = .007 and P = .001, respectively).Conclusions:VR-based digital practice program might be an affordable approach for visual perception and head movement recovery for subacute stroke patients with USN.     

Drug-coated balloon angioplasty versus balloon angioplasty for treating patients with in-stent restenosis in the femoropopliteal artery: A meta-analysis

Background:The introduction of endovascular surgery has led to frequent stent use, although in-stent restenosis (ISR) remains a challenging issue. Drug-coated balloon (DCB) and conventional balloon angioplasty (BA) are common endovascular procedures for addressing ISR in the femoropopliteal artery. However, there is controversy regarding which procedure provides the greatest benefit to patients.Methods:The PubMed, EMBASE, and Cochrane Central Register of Controlled Trials databases were searched for prospective controlled trials that compared DCB and BA for patients with ISR in the femoropopliteal artery. The study has been approved by Ethics Committee of Wuhan Central Hospital.Results:The meta-analysis included 6 prospective trials with 541 patients. We found that DCB use was associated with significant reductions in binary restenosis at 6 months (relative risk [RR]: 0.45, 95% confidence interval [CI]: 0.33–0.63; P < .00001), binary restenosis at 1 year (RR: 0.44, 95% CI: 0.34–0.57; P < .00001), target lesion revascularization (TLR) at 6 months (RR: 0.36, 95% CI: 0.20–0.65; P = .0006), and TLR at 1 year (RR: 0.38, 95% CI: 0.27–0.54; P < .00001). The DCB group also had significantly better clinical improvement (RR: 1.39, 95% CI: 1.13–1.71; P = .002), although we did not detect inter-group differences in terms of death, target vessel thrombosis, or ipsilateral amputation. The brand of DCB may a cause of heterogeneity.Conclusion:Relative to BA, DCB use increases the durability of treatment for ISR in the femoropopliteal artery, based on significant reductions in binary restenosis and TLR at 6–12 months after the procedure. Furthermore, DCB use was associated with better clinical improvement. However, additional randomized controlled trials are needed to validate these findings.     

Improving the discomfort and satisfaction of colonoscopy by distraction with smartphones: A prospective randomized controlled study

Background:Colonoscopy is an uncomfortable procedure. Distraction is thought to reduce pain by decreasing the amount of attention a person spends on a painful stimulus. We aimed to assess the usefulness of smartphones on discomfort associated with the colonoscopy.Methods:We designated 360 enrolled patients according to prospective randomized controlled study into two groups, including smartphone (SP) group (Relaxation by smartphones) and Control group (No relaxation). Measured outcomes included the discomfort, satisfaction, polyp detection rate and the willingness to repeat colonoscopy were analyzed between groups.Results:The pain and distension scores of SP group patients were significantly lower than those of the Control group (2.18 ± 2.80 vs 3.55 ± 3.07, P < .001; 4.15 ± 2.35 vs 4.79 ± 2.36, P = .011, respectively). Importantly, patient-reported satisfaction scores of the SP group were significantly higher than those of the Control group (96.45 ± 7.17 vs 91.12 ± 10.49, respectively; P < .001). Moreover, although there were no statistical differences, patients using smartphones were more likely to have shorter reach cecum times (09m:11 s vs 07m:37 s, P = .116) and more polyp detection rate (13.3% vs 9.4%, P = .246). In addition, more patients using smartphones were willing to repeat colonoscopy but no statistical difference (85.0% vs 81.7%, P = .396).Conclusion:Patient using smartphone is a special manner to increase satisfaction during colonoscopy with a less discomfort and is more likely to be polyp detection rate.     

Patient activation level and its associated factors in adults with chronic pain: A cross-sectional survey

Background:Patients’ capacity to manage their own health can be graded by levels of activation. Highly activated patients tend to have better health outcomes. However, little is known about the activation levels of chronic pain patients in China. This study aimed to identify:

• (1)the activation levels within this population; and
• (2)demographic and pain factors associated with the level of activation.

Methods:In this cross-sectional survey, patients completed a sociodemographic questionnaire, Brief Pain Inventory and Patient Activation Measure (PAM) 13. Patient activation was measured and categorized into Levels 1–4. Its associations with sociodemographic, patient-reported diseases and pain variables were explored using Wilcoxon rank sum test and Kruskal-Wallis H test.Results:Of 338 patients, 84 were excluded. Of the 254 remaining, 51.6% of patients were at lower activation levels (PAM Levels 1 and 2). Higher activation levels (PAM Levels 3 and 4) were recorded in patients with younger age (P = .00005), higher education (P = .0018), non-laboring occupations (P = .0239), and fewer co-morbidities (P = .00615). Intensities of the worst pain (P = .000627), average pain (P = .0213), and current pain (P = .0353), as well as the impact of pain on relationships with others (P = 0.00529), mood (P = .00391), sleep (P = .0132), and interest in life (P = .0248), were negatively correlated with activation levels.Conclusion:Half of the chronic pain patients in this population displayed lower activation levels. Older age, less education, manual labor, more co-morbidities, more intense pain and greater impact of pain on life were associated with lower activation levels. Pain education programs need to target the individual''s PAM level.Registration:This trial was registered in Chinese Clinical Trial Registry. Number: ChiECRCT-20180170     

Graded motor imagery training as a home exercise program for upper limb motor function in patients with chronic stroke: A randomized controlled trial

Purpose:Although several types of occupational therapy for motor recovery of the upper limb in patients with chronic stroke have been investigated, most treatments are performed in a hospital or clinic setting. We investigated the effect of graded motor imagery (GMI) training, as a home exercise program, on upper limb motor recovery and activities of daily living (ADL) in patients with stroke.Methods:This prospective randomized controlled trial recruited 42 subjects with chronic stroke. The intervention group received instruction regarding the GMI program and performed it at home over 8 weeks (30 minutes a day). The primary outcome measure was the change in motor function between baseline and 8 weeks, assessed the Manual Function Test (MFT) and Fugl-Meyer Assessment (FMA). The secondary outcome measure was the change in ADL, assessed with the Modified Barthel Index (MBI).Results:Of the 42 subjects, 37 completed the 8-week program (17 in the GMI group and 20 controls). All subjects showed significant improvements in the MFT, FMA, and MBI over time (P < .05). However, the improvements in the total scores for the MFT, FMA, and MBI did not differ between the GMI and control groups. The MFT arm motion score for the GMI group was significantly better than that of the controls (P < .05).Conclusions:The GMI program may be useful for improving upper extremity function as an adjunct to conventional rehabilitation for patients with chronic stroke.     

Effects of myofascial release on frequency of joint bleedings,joint status,and joint pain in patients with hemophilic elbow arthropathy: A randomized,single-blind clinical trial

Background:Chronic joint injury of the elbow joint is common in patients with hemophilia. Myofascial release is used for the management of pain and functionality in patients with chronic restrictions.Objective:To evaluate the effectiveness of myofascial release in patients with hemophilic elbow arthropathy.Methods:Sixty-nine patients with hemophilia took part in this randomized controlled trial. They were recruited from 10 hemophilia patient Associations. They were randomly allocated to experimental (n = 35) or control group (n = 34). The intervention consisted of three 50-min sessions of fascial therapy over a 3-week period. The intervention included 11 bilaterally administered maneuvers in both upper limbs (from shoulder girdle to forearm). The study variables were frequency of elbow bleeding (self-report), joint status (Hemophilia Joint Health Score), and joint pain (visual analog scale) at baseline, after the intervention, and at the 3-month follow-up.Results:There were significant changes (P < .001) in the repeated measures factor in the frequency of hemarthrosis (F = 20.64), joint status (F = 31.45), and perceived joint pain (F = 30.08). We found group interaction with the (P < .001) in the frequency of hemarthrosis (F = 21.57), joint status (F = 99.98), and perceived joint pain (F = 44.26). There were changes (P < .01) in the pairwise comparison analysis between the pretreatment assessment and the posttreatment and follow-up assessments.Conclusions:Myofascial release decreases frequency of elbow bleedings, and improved joint status and perception of elbow pain in patients with hemophilic elbow arthropathy. Myofascial release may be recommended to improve joint status and joint pain in patients with hemophilic elbow arthropathy.     

Robot-assisted versus laparoscopic minor hepatectomy: A systematic review and meta-analysis

Background:Robot-assisted and laparoscopic surgery are the most minimally invasive surgical approaches for the removal of liver lesions. Minor hepatectomy is a common surgical procedure. In this study, we evaluated the advantages and disadvantages of robot-assisted vs laparoscopic minor hepatectomy (LMH).Methods:A systematic literature search was performed in PubMed, Embase, and the Cochrane Library to identify comparative studies on robot-assisted vs. laparoscopicminor hepatectomy up to February, 2020. The odds ratios (OR) and mean differences with 95% confidence intervals were calculated using the fixed-effects model or random-effects model.Results:A total of 12 studies involving 751 patients were included in the meta-analysis. Among them, 297 patients were in the robot-assisted minor hepatectomy (RMH) group and 454 patients were in the LMH group. There were no significant differences in intraoperative blood loss (P = .43), transfusion rates (P = .14), length of hospital stay (P > .64), conversion rate (P = .62), R0 resection rate (P = .56), complications (P = .92), or mortaliy (P = .37) between the 2 groups. However, the RMH group was associated with a longer operative time (P = .0003), and higher cost (P < .00001) compared to the LMH group. No significant differences in overall survival or disease free survival between the 2 groups were observed. In the subgroup analysis of left lateral sectionectomies, RMH was still associated with a longer operative time, but no other differences in clinical outcomes were observed.Conclusions:Although RMH is associated with longer operation times and higher costs, it exhibits the same safety and effectiveness as LMH. Prospective randomized controlled clinical trials should now be considered to obtain better evidence for clinical consensus.     

Modified Robert Jones Bandage in reducing blood loss in total knee arthroplasty: A meta-analysis of randomized controlled trials

Background:The purpose of this meta-analysis was to assess the effects of Modified Robert Jones Bandage (MRJB) in primary total knee arthroplasty (TKA).Methods:PubMed, EMBASE, the Cochrane Library, Web of Science, and Google Scholar were systematically searched for randomized controlled trials (RCTs). All RCTs were compared to receive either MRJB (study group) or conventional wound dressing (control group) in TKA. Statistical analysis was assessed using RevMan 5.3 software.Results:A total of 5 RCTs involving 362 patients were included in the meta-analysis. No significant difference between the 2 groups was found in terms of total blood loss (Mean difference [MD], –25.41; 95% confidence interval [CI], –90.52 to 39.70; P = .44), intra-operative blood loss (MD, –13.77; 95% CI, –31.84 to 4.29; P = .14), drain blood loss (MD, 0.83; 95% CI, –30.07 to 31.72; P = .96), and transfusion rate (risk ratio, 0.95; 95% CI, 0.55–1.64; P = .86); There was also no significant difference in terms of range of motion (MD, –0.93; 95% CI, –3.64 to 1.79; P = .50), visual analog scale pain sores (MD, –0.02; 95% CI, –0.34 to 0.30; P = .90), and operative time (MD, –3.12; 95% CI, –13.42 to 7.18; P = .55), without increasing the risk of wound-related complications (risk ratio, 0.75; 95% CI, 0.27–2.08; P = .58) in both groups. No deep venous thrombosis occurred in all studies.Conclusions:The current meta-analysis of the available evidence indicates patients with MRJB had not required the additional advantage compared to the conventional wound dressing for TKA. However, more high-quality studies are needed to confirm the above conclusions.Level of Evidence:Level I, therapeutic study.
