Dopamine agonists in restless leg syndrome treatment and their effects on sleep parameters: A systematic review and meta-analysis.

BACKGROUND: Dopamine agonists (DAs) constitute the standard therapeutic scheme for restless leg syndrome (RLS) because they have been proven to be effective. However, DAs may change sleep parameters, thus having adverse effects on patient condition. This meta-analysis clarified the effects of DAs used in RLS treatment on the sleep architecture. METHODS: PubMed, Embase, and Cochrane Central databases were searched for randomized control trials (RCT) (up to October 2023) that discussed the effects of DAs on sleep architecture in patients with RLS. A meta-analysis employing a random-effects model was conducted. The patients were divided into subgroups according to individual DAs and treatment duration (1 day or ≥4 weeks). RESULTS: Thirteen eligible randomized placebo-controlled trials were included in the assessment. The effects of three DAs (i.e., pramipexole, ropinirole, and rotigotine) on rapid eye movement (REM) sleep, slow-wave sleep (SWS), and sleep efficiency (SE) were analyzed. Overall, pramipexole significantly improved SE but decreased the percentage of REM sleep among treated patients. Ropinirole also enhanced SE compared with the placebo group. Rotigotine did not affect SE and REM sleep. Subgroup analysis found that pramipexole used for 1 day and ≥4 weeks significantly diminished the percentage of REM sleep. Ropinirole used for 1 day showed similar REM sleep patterns. Finally, none of the three DAs affected SWS. CONCLUSIONS: This meta-analysis demonstrated that DAs significantly affect sleep parameters.

Quetiapine Oral Solution in Alzheimer's Disease: Efficacy and Dosage Insights from a Real-World Retrospective Study.

BACKGROUND: Neuropsychiatric symptoms (NPS) are distressing for patients with dementia, often accelerating functional decline and nursing home placement. Medications such as quetiapine are used to alleviate NPS, but their side effects require cautious use. Liquid formulations such as quetiapine oral suspension suit specific populations; however, real-world data on their use in patients with dementia are limited. OBJECTIVE: The purpose of this retrospective, naturalistic study was to provide preliminary data on the effects of treatment with quetiapine oral suspension on behavioral and psychiatric disturbances in Alzheimer's disease (AD) outpatients in Taiwan. METHODS: Between January 2022 and June 2023, data were collected from outpatients with a diagnosis of probable AD who received treatment with Qting® (quetiapine oral solution 25 mg/ml). Primary outcome measures were changes in Neuropsychiatric Inventory (NPI) total score and its sub-items from baseline to the endpoint. RESULTS: We recruited 66 AD patients with a mean age of 72.1±7.6 years, most of whom were female (69.7%). Twenty-three patients had data on neuropsychological test and NPI scores before and after quetiapine treatment. There was no significant change in global cognitive function from baseline to the endpoint. A significant reduction in NPI total score after quetiapine treatment was noted, while the effect on NPI sub-items was limited. The average maintenance dose was 1.5±0.6 ml. CONCLUSIONS: We demonstrated our clinical experience of the use of quetiapine oral solution in AD patients with NPS. Our results showed that quetiapine oral solution treatment significantly improved these symptoms at a relatively low dose.

Association of general anesthesia exposure with risk of postoperative delirium in patients receiving transcatheter aortic valve replacement: a meta-analysis and systematic review.

The aim of this meta-analysis was to assess the association of general anesthesia (GA) exposure with the risk of POD in this patient population. Databases including Medline, EMBASE, Cochrane library, and Google Scholar were searched from inception to December 2022. Analysis of 17 studies published between 2015 and 2021 involving 10,678 individuals revealed an association of GA exposure with an elevated risk of POD [odd ratio (OR) = 1.846, 95% CI 1.329 to 2.563, p = 0.0003, I2 = 68.4%, 10,678 patients]. Subgroup analysis of the diagnostic methods also demonstrated a positive correlation between GA exposure and POD risk when validated methods were used for POD diagnosis (OR = 2.199, 95% CI 1.46 to 3.31, p = 0.0002). Meta-regression analyses showed no significant impact of age, male proportion, and sample size on the correlation between GA and the risk of POD. The reported overall incidence of POD from the included studies regardless of the type of anesthesia was between 0.8 and 27%. Our meta-analysis showed a pooled incidence of 10.3% (95% CI 7% to 15%). This meta-analysis suggested an association of general anesthesia with an elevated risk of postoperative delirium, implying the necessity of implementing appropriate prophylactic strategies against this complication when general anesthesia was used in this clinical setting.

Age and sex differences in the association between APOE genotype and Alzheimer's disease in a Taiwan Chinese population.

Introduction: The Apolipoprotein E (APOE) epsilon (ε) 4 allele is a well-established risk factor for late-onset Alzheimer's disease (AD). Reports on white ancestry populations have showed that age, sex, and ethnicity have different effects on the association between APOE genotype and AD. However, studies on Asian populations such as Taiwan Chinese populations are limited. This study aimed to evaluate the association between APOE genotype and AD in a Taiwan Chinese population, and to explore if the association varies by age and sex. Methods: We conducted a case-control study in 725 patients with AD and 1,067 age- and sex- matched controls without dementia from a Taiwan Chinese population. Logistic regression models were used to test the association between AD and APOE genotypes. Secondary analyses considered age (<75 or ≥75 years old), and sex stratified models. Results: The risk of AD was significantly increased for people with at least one copy of APOE ε4 (OR = 2.52, 95% CI = 2.01-3.17, p < 0.001) and in a dose-dependent manner. Our results did not show an statistically significance different in AD risk when women and men carrying APOEε4 were compared. Despite not reaching statistical significance, the risk of APOE ε4 for AD was higher among younger participants (OR = 3.21, 95% CI = 2.26-4.56, p < 0.001) compared to older ones (OR = 2.13, 95% CI = 1.53-2.97, p < 0.001). When considering both sex and age, the risk of AD was higher among older men carrying APOE ε4 (OR = 2.64, 95% CI = 1.51-4.60 in men; OR = 1.90, 95% CI = 1.26-2.86 in women), while women carrying APOE ε4 appeared to have an increased risk at a younger age (OR = 3.29, 95% CI = 2.20-4.93 in women; OR = 2.91, 95% CI = 1.40-6.05 in men). Discussion: The APOE ε4 allele represents a major risk factor for AD in the Taiwanese population. The effect of APOE ε4 allele on AD risk appeared to be stronger among men aged 75 years or more and among younger women.

Association of prognostic nutritional index with prognostic outcomes in patients with glioma: a meta-analysis and systematic review.

Background: The potential link between Prognostic Nutritional Index (PNI) and prognosis in patients with glioma remains uncertain. This meta-analysis was conducted to assess the clinical value of PNI in glioma patients by integrating all available evidence to enhance statistical power. Method: A systematic search of databases including Medline, EMBASE, Google Scholar, and Cochrane Library was conducted from inception to January 8, 2023 to retrieve all pertinent peer-reviewed articles. The primary outcome of the study was to examine the association between a high PNI value and overall survival, while secondary outcome included the relationship between a high PNI and progression-free survival. Results: In this meta-analysis, we included 13 retrospective studies published from 2016 to 2022, which analyzed a total of 2,712 patients. Across all studies, surgery was the primary treatment modality, with or without chemotherapy and radiotherapy as adjunct therapies. A high PNI was linked to improved overall survival (Hazard Ratio (HR) = 0.61, 95% CI: 0.52 to 0.72, p < 0.00001, I2 = 25%), and this finding remained consistent even after conducting sensitivity analysis. Subgroup analyses based on ethnicity (Asian vs. non-Asian), sample size (<200 vs. >200), and source of hazard ratio (univariate vs. multivariate) yielded consistent outcomes. Furthermore, patients with a high PNI had better progression-free survival than those with a low PNI (HR=0.71, 95% CI: 0.58 to 0.88, p=0.001, I2 = 0%). Conclusion: Our meta-analysis suggested that a high PNI was associated with better overall survival and progression-free survival in patients with glioma. These findings may have important implications in the treatment of patients with glioma. Additional studies on a larger scale are necessary to investigate if integrating the index into the treatment protocol leads to improved clinical outcomes in individuals with glioma.

Evaluation of Blepharoptosis in Patients With Refractory Blepharospasm by VISA-Video Recordings, Idiosyncratic Expressions, Sensory Tricks, and Ancillary Procedures.

BACKGROUND: How to evaluate blepharoptosis concomitantly presented with refractory and uncontrollable blepharospasm? To date, there is a paucity of publications on the ideal evaluation methods. An innovative method-video recordings, idiosyncratic facial expressions, sensory tricks, and ancillary procedures (VISA)-is developed for preoperative evaluation, and the surgical outcomes are demonstrated. METHODS: A retrospective study using VISA for blepharoptosis evaluation was conducted on 51 patients with refractory blepharospasm. Based on the evaluation, patients underwent blepharoptosis correction simultaneously besides the selective myectomy and myotomy in situ of the eyelid protractors for blepharospasm. Preoperative and postoperative palpebral fissure height, margin reflex distance 1, ptosis severity, and levator function were assessed to identify the effectiveness of VISA. All the procedures were performed by the senior author C.-S.L. RESULTS: There were 42 patients diagnosed with essential blepharospasm and 9 patients with Meige syndrome. Forty-one patients (82/102 eyelids [80.4%]) had concomitant blepharoptosis and blepharospasm. Ptosis severity was mild in 21 eyelids (25.6%), moderate in 12 eyelids (14.6%), and severe in 49 eyelids (59.8%). Preoperative/postoperative (6 months) values of palpebral fissure height, margin reflex distance 1, and levator function were 4.70 ± 2.45 mm/8.35 ± 1.33 mm (P < 0.05), -0.30 ± 3.19 mm/3.73 ± 1.05 mm (P < 0.05), and 13.07 ± 2.56 mm/13.68 ± 2.34 mm (P < 0.05), respectively. Undercorrection and revision rate reported 9.8% and 3.7%, individually. CONCLUSIONS: VISA approach overcomes the difficulty of blepharoptosis assessment in patients with refractory blepharospasm. It provides useful preoperative information required for adequate blepharoptosis correction in blepharospasm surgery and yielded desirable outcomes.

Selective Myectomy and Myotomy In Situ for the Management of Refractory Blepharospasm in Meige Syndrome.

BACKGROUND: Meige syndrome is characterized by involuntary blepharospasm and varied subphenotypes of oromandibular tonic-clonic muscle contraction. Despite botulinum toxin (BTx) being the mainstay of treatment for Meige syndrome, a small subset of patients remain refractory to its effects because the disease is a form of functional blindness. An integrative surgical procedure combining selective myectomy and myotomy in situ of eyelid protractors, blepharoptosis correction, and tightening of the lower eyelid laxity was first applied to treat refractory blepharospasm in patients with Meige syndrome. MATERIALS AND METHODS: This study is a retrospective review conducted on 24 patients with refractory Meige syndrome between 2013 and 2020. Besides selective myectomy and myotomy in situ of eyelid protractors, levator plication and lateral tarsoplasty or canthopexy was performed for blepharoptosis correction and lower eyelid tightening, respectively. Patient demographics, associated diseases, medical treatment history, associated surgical procedures, final aesthetic outcomes, and therapeutic effects as reflected by changes in function disability score and Botox (BTx) treatment were thoroughly recorded and analyzed. RESULTS: The mean age of the patients was 65.2 ± 8.9 years. Twenty-one patients (87.5%) received blepharoptosis correction by levator plication with an average of 11.2 ± 2.9 mm in length. Lateral tarsoplasty was performed in 16 patients (66.7%) by pentagonal tarsal resection with an average of 3.9 ± 0.8 mm in width. Five patients (20.8%) received lateral canthopexy. Among the total of 96 operated eyelids, scar revision with fat graft was performed in 3 eyelids (3.1%). The average amount of BTx treatment decreased from 49.2 ± 12.8 U once every 2.7 ± 0.8 months before surgery to 35.4 ± 7.8 U once every 3.8 ± 0.7 months after surgery. Function disability score improved from 76.7 ± 17.5% preoperatively to 15.6 ± 9.9% postoperatively ( P < 0.001). Only 3 upper eyelids (3.1%) received scar revision and fat grafting due to minor postoperative contour depression. All patients expressed high satisfaction with both functional and aesthetic outcomes (Likert scale 4.5 ± 0.5). CONCLUSIONS: Selective myectomy and myotomy in situ of eyelid protractors combining blepharoplasty correction and lower eyelid tightening can produce long-lasting functional and aesthetic results with minimal complication in patients with refractory Meige syndrome.

Prevalence and Risk Factors of Neuropsychiatric Symptoms in Institutionalized Patients with Parkinson's Disease in Taiwan: A Nationwide Observational Study.

Neuropsychiatric symptoms (NPSs) are known to be frequent in Parkinson's disease (PD) with great impacts on the quality of life, but reports about the prevalence in institutions are few. Our aim was to investigate the prevalence of and risk factors for NPSs in institutionalized patients with PD in Taiwan. The National Health Research Institute executed a cross-sectional, community-based, observational study on residential long-term care service institutions. The diagnosis of PD was determined by physicians with the estimated Hoehn and Yahr stage of PD according to the EQ-5D-5L questionnaire. A total of 370 patients with PD (80.1 ± 9.94 years old, 55.1% females) were included, and 139 (37.6%) had more than one NPS in the prior 3 months. The top three NPSs were nighttime behavior (65 (17.6%)), depression (53 (14.3%)), and fear/anxiety (49 (13.2%)). There were no differences between those with NPS and those without NPS in terms of age, gender, education, Mini-Mental State Examination, or Hoehn and Yahr stage. However, multivariate logistic regression analysis showed that genitourinary disease (odds ratio (OR) = 3.13; 95% confidence interval (95%CI) = 1.77-5.51) and psychiatric disorders (OR = 5.18; 95%CI = 3.09-8.69) may be associated with increased risk of NPSs. Increased physical restraint was observed in residents with advanced PD. Genitourinary disease and psychiatric disorders appear to increase the risk of NPSs in institutionalized residents with PD.

What factors contribute to the need for physical restraint in institutionalized residents in Taiwan?

BACKGROUND: In Taiwan, physical restraint is commonly used in institutions to protect residents from falling or injury. However, physical restraint should be used cautiously to avoid side effects, such as worse cognition, mobility, depression, and even death. OBJECTIVES: To identify the rate of physical restraint and the associated risk factors in institutionalized residents in Taiwan. METHODS: A community-based epidemiological survey was conducted from July 2019 to February 2020 across 266 residential institutions. Among the estimated 6,549 residents being surveyed, a total of 5,752 finished the study. The questionnaires were completed by residents, his/her family or social workers. The cognition tests were conducted by specialists and a multilevel analysis approach was used to identify cognition/disability/medical history/special nursing care/BPSD risk factors for physical restraints. RESULTS: Of the 5,752 included institutionalized residents, 30.2% (1,737) had been previously restrained. Older age, lower education level, lower cognitive function, higher dependence, residents with cerebrovascular disease, pulmonary disease, dementia, and intractable epilepsy, all contributed to a higher physical restraint rate, while orthopedic disease and spinal cord injury were associated with a lower physical restraint rate. Furthermore, residents with special nursing care had a higher restraint rate. Residents with most of the behavior and psychological symptoms were also associated with an increased restraint rate. CONCLUSIONS: We studied the rate of physical restraint and associated risk factors in institutionalized residents in Taiwan. The benefits and risks of physical restraint should be evaluated before application, and adjusted according to different clinical situations.

General anesthesia but not conscious sedation improves functional outcome in patients receiving endovascular thrombectomy for acute ischemic stroke: A meta-analysis of randomized clinical trials and trial sequence analysis.

Background: This study aimed at comparing the difference in prognostic outcomes between patients receiving general anesthesia (GA) and conscious sedation (CS) for endovascular thrombectomy after acute ischemic stroke. Methods: Databases from Medline, Embase, Google scholar, and Cochrane library were searched for randomized controlled studies (RCTs) comparing patients undergoing GA and CS for endovascular thrombectomy following anterior circulation ischemic stroke. The primary outcome was frequency of 90-day good functional outcome [defined as modified Rankin Scale score of ≤ 2], while secondary outcomes included successful recanalization rate (SRR) [i.e., modified thrombolysis in cerebral infarction = 2b or 3], mortality risk, symptomatic intracranial hemorrhage (ICH), procedure-related complications, hypotension, pneumonia, neurological outcome at post-procedure 24-48 h, and puncture-to-recanalization time. Results: Six RCTs including 883 patients published between 2016 and 2022 were included. Merged results revealed a higher SRR [risk ratio (RR) = 1.11, 95% CI: 1.03-1.2, p = 0.007; I 2 = 29%] and favorable neurological outcomes at 3-months (RR = 1.2, 95% CI: 1.01-1.41, p = 0.04; I 2 = 8%) in the GA group compared to CS group, without difference in the risk of mortality (RR = 0.88), symptomatic ICH (RR = 0.91), procedure-related complications (RR = 1.05), and pneumonia (RR = 1.9) as well as post-procedure neurological outcome (MD = -0.21) and successful recanalization time (MD = 3.33 min). However, GA was associated with a higher risk of hypotension compared with that of CS. Conclusion: Patients with acute anterior circulation ischemic stroke receiving GA were associated with a higher successful recanalization rate as well as a better 3-month neurological outcome compared to the use of CS. Further investigations are warranted to verify our findings. Systematic review registration: www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022342483, identifier: CRD42022342483.

Association between Cerebral Coordination Functions and Clinical Outcomes of Alzheimer's Dementia.

Background: Alzheimer's dementia (AD) is a degenerative disease that impairs cognitive function, initially, and then motor or other function, eventually. Motor coordination function impairment usually accompanies cognition impairment but it is seldom examined whether it can reflect the clinical outcomes of AD. Methods: 113 clinically diagnosed AD patients with a mean age of 78.9 ± 6.9 years underwent an annual neuropsychological assessment using the Mini-Mental State Examination (MMSE), the Cognitive Abilities Screening Instrument (CASI), the Sum of Boxes of Clinical Dementia Rating (CDR-SB), and the CDR. The cerebral coordination function was evaluated through correlations among 15 joints with a kinetic depth sensor annually. An intra-individual comparison of both cognitive and motor coordination functions was performed to examine their correlations. Results: The changes in coordination function in the lower limbs can significantly reflect the clinical outcomes, MMSE (p < 0.001), CASI (p = 0.006), CDR (p < 0.001), and CDR-SB (p < 0.001), but the changes in upper limbs can only reflect the clinical outcome in CDR (p < 0.001). Conclusions: The use of a kinetic depth sensor to determine the coordination between joints, especially in lower limbs, can significantly reflect the global functional and cognitive outcomes in AD. Such evaluations could be another biomarker used to evaluate non-cognitive outcomes in AD for clinical and research purposes.

The impact of esophageal device insertion on cuff pressure of endotracheal tube: a literature review and meta-analysis.

The impact of intraoperative esophageal device insertion (EDI) on endotracheal tube (ET) cuff inflation pressure remains unclear. Electronic databases including Medline, Embase, Google scholar, Web of Science™ and Cochrane Central Register of Controlled Trials were searched for studies involving EDI after placement of ETs from inception to July 7, 2022. The primary outcome was risk of high cuff pressure, while the secondary outcomes were increases in cuff pressure following EDI. Difference between adults and children was investigated with subgroup analysis. There were ten eligible studies (observation study, n = 9, randomized controlled study, n = 1) involving a total of 468 participants. EDI notably increased the risk of high cuff pressure (n = 7, risk ratio: 12.82, 95% confidence interval: 4.9 to 33.52, subgroup analysis: p = 0.008). There were significant elevations in cuff pressure in adults and children both during (13.42 and 7.88 cmH2O, respectively, subgroup analysis: p = 0.15) and after (10.09 and 3.99 cmH2O, respectively, subgroup analysis: p = 0.0003) EDI. Our results revealed an over 12-fold increase in the risk of high endotracheal tube cuff pressure in patients, especially adults, receiving EDI under endotracheal anesthesia. There were significant increases in both adults and children despite a higher increase in the former after device insertion.

Impact of intravenous and topical lidocaine on clinical outcomes in patients receiving propofol for gastrointestinal endoscopic procedures: a meta-analysis of randomised controlled trials.

BACKGROUND: The efficacy of i.v. or topical lidocaine as an anaesthesia adjunct in improving clinical outcomes in patients receiving gastrointestinal endoscopic procedures under propofol sedation remains unclear. METHODS: Electronic databases (MEDLINE, EMBASE, and Cochrane Library) were searched for RCTs comparing the clinical outcomes with or without lidocaine application (i.v. or topical) in patients receiving propofol for gastrointestinal endoscopic procedures from inception to 29 March 2021. The primary outcome was propofol dosage, while secondary outcomes included procedure time, recovery time, adverse events (e.g. oxygen desaturation), post-procedural pain, and levels of endoscopist and patient satisfaction. RESULTS: Twelve trials (1707 patients) published between 2011 and 2020 demonstrated that addition of i.v. (n=7) or topical (n=5) lidocaine to propofol sedation decreased the level of post-procedural pain (standardised mean difference [SMD]=-0.47, 95% confidence interval [CI]: -0.8 to -0.14), risks of gag events (risk ratio [RR]=0.51, 95% CI: 0.35-0.75), and involuntary movement (RR=0.4, 95% CI: 0.16-0.96). Subgroup analysis demonstrated that only i.v. lidocaine reduced propofol dosage required for gastrointestinal endoscopic procedures (SMD=-0.83, 95% CI: -1.19 to -0.47), increased endoscopist satisfaction (SMD=0.75, 95% CI: 0.21-1.29), and shortened the recovery time (SMD=-0.83, 95% CI: -1.45 to -0.21). Intravenous or topical lidocaine did not affect the incidence of oxygen desaturation (RR=0.72, 95% CI: 0.41-1.24) or arterial hypotension (RR=0.6, 95% CI: 0.22-1.65) and procedure time (SMD=0.21, 95% CI: -0.09 to 0.51). CONCLUSION: This meta-analysis demonstrated that i.v. or topical lidocaine appears safe to use and may be of benefit for improving propofol sedation in patients undergoing gastrointestinal endoscopic procedures. Further large-scale trials are warranted to support our findings.

Efficacy of intraoperative intravenous lidocaine for postoperative analgesia following bariatric surgery: a meta-analysis of randomized controlled studies.

BACKGROUND: The impact of intravenous lidocaine in adults undergoing laparoscopic bariatric surgeries (LBS) remains unclear. OBJECTIVES: This study aimed at investigating the effect of intravenous lidocaine on postoperative opioid consumption and recovery following LBS. SETTING: Meta-analysis. METHODS: We searched databases including MEDLINE, Embase, Google Scholar, and the Cochrane Library for randomized controlled trials that evaluated the use of intravenous lidocaine compared to placebo only prior to May 2021. The primary outcome was 24-hour postoperative opioid consumption, while secondary outcomes included pain score, quality of recovery (QOR)-40 score, length of hospital stay (LOS), and postoperative nausea/vomiting (PONV). RESULTS: Seven trials (496 participants) were included. Intraoperative intravenous lidocaine significantly reduced 24-hour equivalent morphine consumption (mean difference [MD]: -11.97 mg; 95% confidence interval [CI]: -23.12 to -.83), pain score at 1 to 3 hours (MD: -.77; 95% CI: -1.5 to -.04), and LOS (MD: -8.93 hr; 95% CI: -13.41 to -4.44) without positive impact on 24-hour pain score and PONV. There was also an increase in time to first opioid requirement (MD: 20.23 min; 95% CI: 11.76-28.7) and QOR-40 score (MD: 24.38; 95% CI: 5.57-43.18). However, sensitivity analysis demonstrated evidence supporting the beneficial effect of lidocaine only for time to first opioid requirement and QOR-40. The associations of intraoperative intravenous lidocaine with reductions in morphine consumption, pain score at 1 to 3 hours, and LOS after LBS were also weak. CONCLUSION: Intraoperative intravenous lidocaine during LBS prolonged time to first opioid requirement and improved quality of recovery postoperatively without 24-hour pain or nausea/vomiting benefits. Due to the small number of trials, larger studies are warranted to verify our findings.

Association between perioperative intravenous lidocaine and subjective quality of recovery: A meta-analysis of randomized controlled trials.

STUDY OBJECTIVE: To evaluate the impact of perioperative intravenous lidocaine on the quality of recovery (QoR) following surgery. DESIGN: Meta-analysis of randomized controlled trials (RCTs). SETTING: Postoperative care. INTERVENTION: Intravenous lidocaine during perioperative period. PATIENTS: Adults undergoing surgery under general anesthesia. MEASUREMENTS: The primary outcome was postoperative QoR measured with QoR-40 questionnaire, while the secondary outcomes included five individual dimensions (i.e., emotional, state, physical comfort, psychological support, physical independence, and pain) of QoR-40, intraoperative opioid consumption, and risk of chronic postsurgical pain (CPSP). MAIN RESULTS: Medline, Cochrane Library, Google scholar, and EMBASE databases were searched from inception to June 2021. Fourteen RCTs involving 1148 patients in total undergoing elective surgery published from 2012 to 2021 were included. QoR-40 scores were evaluated at postoperative 24 h (12 trials), 72 h (one trial), and Day 5 (one trial), respectively. Pooled results revealed significantly higher global [mean difference (MD) = 9.65, 95% confidence interval (CI): 6.33 to 12.97; I2 = 97%; 13 RCTs; n = 1085] and individual dimension QoR-40 scores in the lidocaine group than those in placebo group. Subgroup analysis demonstrated no significant impact of the type of surgery, age, gender, surgical time, anesthetic technique, lidocaine dosage, and time of assessment on global QoR-40 scores. The use of intravenous lidocaine was associated with a significant reduction in intraoperative remifentanil consumption compared with that in the placebo group (standardized MD = -0.91, 95%CI: -1.32 to -0.51; I2 = 86%; 10 RCTs; n = 799). There was no difference in risk of CPSP between the two groups [relative risk (RR) = 0.65, 95%CI: 0.33 to 1.25; I2 = 58%; 4 RCTs; n = 309]. CONCLUSION: Our results verified the efficacy of intravenous lidocaine for enhancing postoperative quality of recovery by using a validated subjective tool and reducing intraoperative remifentanil consumption in patients receiving elective surgery under general anesthesia. Further studies are warranted to verify its efficacy in the acute care setting.

Mortality and risk factors associated with pulmonary embolism in coronavirus disease 2019 patients: a systematic review and meta-analysis.

To determine, in patients with coronavirus disease 2019 (COVID-19) infection, the associations of pulmonary embolism (PE) with mortality and risk factors for PE as well as the therapeutic benefit of anticoagulant prophylaxis. Embase, PubMed, Cochrane controlled trials register, and Web of Science databases were searched from inception to October 10, 2020. We included all published trials on PE in patients diagnosed with COVID-19 with eligibility of the trials assessed following the PRISMA guidelines. Sixteen clinical trials with 5826 patients were eligible. There were significant associations of PE with the male gender [odd ratio (OR) = 1.59, 95% CI 1.28-1.97], mechanical ventilation (OR = 3.71, 95% CI 2.57-5.36), intensive care unit admission (OR = 2.99, 95% CI 2.11-4.23), circulating D-dimer [mean difference (MD) = 5.04 µg/mL, 95% CI 3.67-6.42) and CRP (MD = 1.97 mg/dL, 95% CI 0.58- 3.35) concentrations without significant correlation between PE and mortality (OR = 1.31, 95% CI 0.82-2.08) as well as other parameters or comorbidities. After omitting one trial with strict patient selection criteria for anticoagulant prophylaxis, significant prophylactic benefit was noted (OR = 0.31, 95% CI 0.1-0.91). Our findings identified the risk factors associated with PE in COVID-19 patients and supported the therapeutic benefit of anticoagulant prophylaxis against PE in this patient population.

Effect of Intraoperative Computed Tomography in Microelectrode Recording during Frameless Stereotactic Deep Brain Stimulation for Parkinson Disease.

BACKGROUND: Microelectrode recording (MER)-guided deep brain stimulation (DBS) remains the standard electrophysiological procedure to place the DBS lead at the optimal target. When single-track MER or test stimulation yields suboptimal results, trajectory adjustments are needed. Intraoperative computed tomography (iCT) can be useful to visualize the microelectrode and verify possible adjustments. The aim of this study was to evaluate the effect of iCT in MER during frameless stereotactic DBS for Parkinson disease (PD). METHODS: We retrospectively collected 28 PD patients, of whom 19 received iCT and 9 did not, and measured intracranial volume, cerebral volume, cerebrospinal fluid volume, and pneumocephalus volume. Euclidean distance was assessed according to merged preoperative brain CT and magnetic resonance imaging and postoperative brain CT. RESULTS: Fifty-six hemispheres in the 28 patients were analyzed for MER tracks. The patients who received iCT had a significantly lower mean number of MER tracks (1.6 vs. 2.6, P = 0.013) and lower mean Euclidean distance (2.2 mm vs. 2.7 mm, P = 0.033) compared with those who did not receive iCT. Although there was a trend of a decrease in pneumocephalus using intraoperative imaging, there was no significant difference in surgical time. CONCLUSIONS: iCT can reduce the number of MER tracks and increase surgical accuracy. Further studies are warranted to investigate whether iCT can reduce surgical complications and improve surgical outcomes.

The effects of lacosamide on cognitive function and psychiatric profiles in patients with epilepsy.

BACKGROUND: Cognitive and psychiatric problems are common in people with epilepsy. They can have multiple causes, including structural brain lesions, the active epilepsy, and the effect of anti-epileptic therapy. Since patients' treatment compliance and quality of life are affected by cognitive and emotional status, it is crucial for clinicians to understand how anti-seizure medications (ASMs) affect cognition and mood, and to choose the proper ASM. OBJECTIVE: To conduct a literature review of the impact on cognition and mood status of lacosamide (LCM) in people with epilepsy. METHODS: Wesearched PubMed, the Cochrane Database of Systematic Reviews and reference lists of articles for all types of articles with no limitations on publication date. RESULTS: A total of 251 records were obtained, including 247 articles in PubMed and 4 articles from reference lists. We included 2 meta-analyses, one randomized controlled trials and 14 observational studies after the screening process. Most studies agree LCM has low risk of treatment-emergent adverse events (TEAEs) on cognition. Comparisons with other ASMs, LCM may be preferable to carbamazepine, topiramate and perampanel, and not inferior to lamotrigine. In spite of low incident rate, depression is the most common psychiatric change of LCM. There are no consistent positive or negative psychiatric effects of LCM. CONCLUSION: Lacosamide has limited impact on cognitive and mood status in this review. Several factors including mechanism of co-administration of ASMs and personal history of psychiatric disorder should be considered as important in the development of cognitive and psychiatric side effects. However, the heterogeneity between studies make the quality of evidence weaker and further trials are needed.

Risk factors for depression in patients with Parkinson's disease: A nationwide nested case-control study.

OBJECTIVES: Patients with Parkinson's disease (PD) have higher prevalence of depression than the general population; however, the risk factors for depression in PD remain uncertain. METHODS/DESIGN: Using the 2000-2010 Taiwan National Health Insurance Research Database, we selected 1767 patients aged ≧ 40 years with new-onset PD during 2000-2009. Among them, 324 patients with a new incidence of depression were enrolled as cases and 972 patients without depression were randomly selected as controls. The groups were frequency-matched at a ratio of 1:3 by age, sex, and index year. Thus, this nested case-control study compared differences between the cases and the controls. Logistic regression models were used to identify risk factors for depression in PD. RESULTS: Compared with the controls, the odds ratio (OR) of anxiety disorders in the cases was 1.53 (95% confidence interval [95% CI], 1.16-2.02; P = 0.003), after adjusting for the confounding factors of age, sex, index year, geographic region, urban level, monthly income, and other coexisting medical conditions. The OR for sleep disturbances in the cases was 1.49 (95% CI, 1.14-1.96; P = 0.004) compared to the controls, after adjusting these confounding factors. Hence, the risk factors for depression in PD were nonsignificantly associated with physical comorbidities. CONCLUSIONS: In the present study, depression in PD was significantly associated with anxiety disorders and sleep disturbances. Integrated care for early identification and treatment of neuropsychiatric comorbidities is crucial in patients with new-onset PD so as to prevent further PD degeneration.
