Abstract Introduction Single-centre studies have shown a high prevalence of undiagnosed cognitive impairment in patients undergoing vascular surgery. The aim of this meta-analysis was to estimate the pooled prevalence of cognitive impairment in vascular surgery patients. Methods A systematic review and meta-analysis was performed of studies reporting cognitive impairment in vascular surgery patients (PROSPERO registration: CRD42019134684). Databases searched included: Medline, Embase, Emcare, CINAHL, PsychINFO and Scopus. Studies were excluded if they: did not use a validated cognitive assessment tool, included patients with asymptomatic or sub-threshold (for treatment) disease, or excluded patients with cognitive impairment. Quality of included studies was assessed using Newcastle-Ottawa scores (NOS), risk of bias was assessed using the ROBINS-E tool, and quality of evidence assessed using GRADE criteria. A pooled estimate of prevalence was calculated using the inverse-variance method separately for carotid artery disease (CAD), lower extremity arterial disease (LEAD), and studies including patients with multiple vascular surgery presentations. Data were pooled using random effects models and estimated prevalence presented with 95% confidence intervals (95%CI). Subgroup analyses were performed by cognitive assessment tool used. Authors of 24 studies meeting inclusion criteria that did not report numbers of cognitively impaired patients were contacted to enable inclusion: responses are awaited. Results After de-duplication of search results, 7,169 records were screened and 11 studies (911 patients) included in the meta-analysis. Nine studies were deemed high quality (NOS ≥7) however 8 studies had a serious risk of bias. Only one study explicitly stated provision for recruiting patients without capacity. Six different tools were used to assess cognitive function (MoCA, MMSE, ACE-R, HDS-R, Mini-Cog and a global cognitive score). Two studies found an association of cognitive impairment with post-op delirium whilst one did not, and a further study showed an association with increased length of stay. Pooled estimate of prevalence of cognitive impairment in CAD patients was 38% (95%CI 17%, 62%; 7 studies), and in “vascular surgery patients” was 61% (95%CI 47%, 74%, 3 studies). Only one study reported prevalence of cognitive impairment in LEAD patients alone of 19% (95%CI 14%, 24%). Quality of evidence was moderate to very low. Conclusions Cognitive impairment is highly prevalent in vascular surgery patients highlighting the need for close collaboration between vascular surgeons and geriatricians.

BACKGROUND Memory, one of the main cognitive functions, is known to decline by age. Serious games have been used for improving memory among the elderly. The effectiveness of serious games in improving memory has been investigated by several systematic reviews; however, they are limited by design and methodological weaknesses. OBJECTIVE This study aims to assess the effectiveness of serious games in improving memory among the elderly with cognitive impairment. METHODS A systematic review of randomized controlled trials (RCTs) was carried out. The search sources included searching 8 databases, screening reference lists of the included studies and relevant reviews, and checking studies that cited the included studies. Two reviewers independently carried out the study selection, data extraction, risk of bias assessment, and quality of evidence appraisal. Extracted data were synthesized using a narrative approach and a statistical approach (i.e., meta-analysis), as appropriate. RESULTS Out of 466 citations retrieved, 18 studies met the eligibility criteria of this review. Of those, 15 RCTs were eventually included in 10 meta-analyses. We found that serious games are more effective than no or passive interventions in improving non-verbal memory (P=0.002) and working memory (P=0.02), but not verbal memory (P=0.13). The review also showed that serious games are more effective than conventional exercises in improving verbal memory (P=0.004), but not for non-verbal memory (P=0.12) and working memory (P=0.49). Serious games were as effective as conventional cognitive activities in improving verbal memory (P=0.07), non-verbal memory (P=0.94), and working memory (P=0.08) among the elderly with cognitive impairment. Lastly, the effect of adaptive serious games on working memory was comparable to non-adaptive serious games (P=0.08). CONCLUSIONS Serious games have the potential to improve verbal, non-verbal, and working memory among elderly people with cognitive impairment. However, our findings should be interpreted cautiously given that most meta-analyses were based on a few studies (≤3) and judged to have a low quality of evidence. Therefore, serious games should be offered as supplemental to existing proven and safe interventions, rather than a complete substitute until further, more robust evidence is available. Future studies should investigate the short and long-term effects of serious games on memory and other cognitive abilities among people from different age groups with or without cognitive impairment.

Meniscal Lesions

Abstract Background Meniscal lesions are common and are associated with the development of knee osteoarthritis. Knee-straining activities at work such as kneeling or squatting cause high biomechanical stresses on the knee joints that can lead to acute or chronic injuries. The objective of this systematic review is to update the evidence on the potential relationship between occupational risk factors and meniscal lesions. Methods We searched the Medline, Embase and Web of Science databases until August 2021 to identify epidemiological observational studies on the association between occupational risk factors and meniscal lesions. Study selection, data extraction and risk of bias assessment were performed independently by two reviewers. Effect measures were extracted from individual studies and pooled with random effects meta-analysis. Heterogeneity analyses were conducted. We used GRADE (Grades of Recommendations, Assessment, Development and Evaluation) to assess the overall quality of evidence. Results The database search resulted in 11,006 references, and 46 additional studies were identified through hand search. Twenty-two studies (represented in 25 publications) met the predefined eligibility criteria and nine records were included in the meta-analysis. There was only one study with an overall low risk of bias. Significant associations between occupational risk factors and the development of meniscal lesions were found for kneeling (effect size (ES) 2.15, 95% CI 1.67–2.76), squatting (ES 2.01, 95% CI 1.34–3.03), climbing stairs (ES 2.28, 95% CI 1.58–3.30), lifting and carrying weights ≥ 10 kg (ES 1.63, 95% CI 1.35–1.96), lifting and carrying weights ≥ 25 kg (ES 1.56, 95% CI 1.08–2.24), playing football on a professional level (ES 5.22, 95% CI 3.24–8.41), working as a hard coal miner (ES 5.23, 95% CI 2.16–12.69) and floor layers (ES 1.99, 95% CI 1.43–2.78). The overall quality of evidence according GRADE was moderate to low. Conclusion We found consistent evidence of an increased risk of meniscal lesions by occupational knee-straining exposures. Our findings are important for the development of preventive strategies to reduce work-related knee disorders and work absence. Trial registration PROSPERO (registration no. CRD42020196279).

This systematic review and meta-analysis evaluated if ketorolac reduces the intensity of postoperative pain after impacted third molars surgery in adults compared to the use of tramadol. A comprehensive search was performed in the MEDLINE/PubMed, Scopus, Web of Science, LILACS, BBO, EMBASE, Cochrane Library, SIGLE and grey literature, in accordance with the PRISMA guidelines. The quality of the evidence was evaluated using the GRADE approach. Meta-analysis was performed on studies considered at low risk of bias. After duplicates removal, 4526 articles were identified, but only nine studies were included for qualitative analysis. After updating in 2021, four studies were added, totaling 13 studies included for qualitative analysis. Only two studies, classified at “low” risk of bias, were included in the meta-analysis of the primary outcome. The difference in means for pain intensity (moderate quality of evidence due to imprecision) was – 0.27 (95% CI = – 0.82 to 0.28; p = 0.34). Data from adverse effects (low quality of evidence due to very serious issues in imprecision) was just reported in one study at “low” risk of bias. Data was not heterogeneous (Chi2 test p = 0.14; I2 = 55%). It was not possible to evaluate any secondary outcomes (time to first rescue analgesic drug in h, total amount of analgesics consumed and adverse effects) due to low number of studies included. There is a lack of strong evidence to assure the superiority of ketorolac or tramadol in reducing the postoperative pain after extraction of impacted third molars.

Abstract Funding Acknowledgements Type of funding sources: Other. Main funding source(s): This project was supported by the MRes programme in the Institute of Life Course and Medical Sciences at The University of Liverpool. Thyroid hormones can act directly and indirectly on the cardiovascular system and studies have demonstrated associations between overt and subclinical thyroid dysfunction and adverse cardiovascular outcomes including heart failure, myocardial infarction, and coronary heart disease. The aim of this study was to assess the association between subclinical thyroid dysfunction and atrial fibrillation (AF).  The protocol was registered on PROSPERO (CRD42020221565). MEDLINE and Scopus were searched from inception to 13th November 2020 for studies investigating subclinical thyroid dysfunction and incident AF. Risk of bias was assessed using the Risk of Bias Assessment Tool (RoBANS). The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool. Subgroup analysis was performed for post-operative and non-post-operative AF. 5413 records were identified. Nine cohort studies were suitable for inclusion in the systematic review, of which seven studies were included in the meta-analysis. The meta-analysis comprised 595,058 patients. Subclinical hyperthyroidism was associated with a 99% increase in the risk of incident AF (Risk ratio (RR): 1.99; 95% confidence intervals (CI); 1.43 to 2.77; p < 0.0001; I² = 67%). Subclinical hypothyroidism was also associated with a greater risk of AF (RR: 1.24; 95% CI; 1.05 to 1.47; p = 0.01; I² = 65%). Subgroup analysis demonstrated a 76% increase in the risk of post-operative AF in patients with subclinical hypothyroidism compared to euthyroid post-operative patients (RR: 1.76; 95% CI; 1.36 to 2.28; p < 0.0001; I² = 0%). Six studies were rated as low risk of bias and three as medium risk of bias according to the RoBANS tool. The quality of evidence for AF in subclinical hyper- and hypothyroid patients was low. Subclinical hyperthyroidism and subclinical hypothyroidism were associated with a higher risk of incident AF and post-operative AF, respectively. The quality of the current evidence is low and ideally a randomised controlled trial should be conducted to confirm these associations and assess impacts of treatments. Abstract Figure.

Abstract This systematic review and meta-analysis aimed to analyze the efficacy and safety of Sihogayonggolmoryeo-tang (SGYMT), a classical herbal medicine consisting of 11 herbs, for treatment of post-stroke depression (PSD). Thirteen databases were comprehensively searched from their inception dates until July 2019. Only randomized controlled trials (RCTs) using SGYMT as a monotherapy or adjunctive therapy for PSD patients were included. Where appropriate data were available, meta-analysis was performed and presented as risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CIs). We assessed the quality of RCTs using the Cochrane risk of bias tool and the Jadad scale. The quality of evidence for each main outcome was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Twenty-one RCTs with 1,644 participants were included. In the comparison between the SGYMT and antidepressants groups, the SGYMT group scored significantly lower on both the Hamilton Depression Scale (HAMD) (8 studies; MD −2.08, 95% CI −2.62 to −1.53, I2 = 34%) and the National Institutes of Health Stroke Scale (NIHSS) (2 studies; MD −0.84, 95% CI −1.40 to −0.29, I2 = 19%), and significantly higher on the Barthel index (3 studies; MD 4.30, 95% CI 2.04 to 6.57, I2 = 66%). Moreover, the SGYMT group was associated with significantly fewer adverse events (6 studies; RR 0.13, 95% CI 0.05 to 0.37, I2 = 0%) than the antidepressants group. In the subgroup analysis, SGYMT treatment consistently reduced HAMD scores within the first 8 weeks of treatment, but thereafter this difference between groups disappeared. Comparisons between SGYMT combined with antidepressants, and antidepressants alone, showed significantly lower scores in the combination group for both HAMD (7 studies; MD = −6.72, 95% CI = −11.42 to −2.01, I2 = 98%) and NIHSS scores (4 studies; MD −3.03, 95% CI −3.60 to −2.45, I2 = 87%). In the subgroup analysis, the reductions of HAMD scores in the SGYMT combined with antidepressants group were consistent within 4 weeks of treatment, but disappeared thereafter. The quality of RCTs was generally low and the quality of evidence evaluated by the GRADE approach was rated mostly “Very low” to “Moderate.” The main causes of low quality ratings were the high risk of bias and imprecision of results. Current evidence suggests that SGYMT, used either as a monotherapy or an adjuvant therapy to antidepressants, might have potential benefits for the treatment of PSD, including short-term reduction of depressive symptoms, improvement of neurological symptoms, and few adverse events. However, since the methodological quality of the included studies was generally low and there were no large placebo trials to ensure reliability, it remains difficult to draw definitive conclusions on this topic. Further well-designed RCTs addressing these shortcomings are needed to confirm our results.

Cancer-related cognitive impairment (CRCI) occurs frequently in patients living with cancer, with consequences on quality of life. Recently, research on the management of these difficulties has focused on computerized cognitive stimulation and computerized physical activity programs. This systematic review presents the state of knowledge about interventions based on computerized-cognitive stimulation and/or physical activity to reduce CRCI. The review followed the PRISMA guidelines. A search was conducted in PUBMED and Web of Science databases. Risk of bias analysis was conducted using the Rob2 tool and the quality of evidence was conducted following the GRADE approach. A total of 3776 articles were initially identified and 20 of them met the inclusion criteria. Among them, sixteen investigated computerized-cognitive stimulation and four computerized-physical activity. Most of the studies were randomized controlled trials and assessed the efficacy of a home-based intervention on objective cognition in adults with cancer. Overall, cognitive improvement was found in 11/16 computerized-cognitive stimulation studies and 2/4 computerized-physical activity studies. Cognitive stimulation or physical activity improved especially cognitive complaints, memory, and attention. These results suggest the efficacy of both computerized-cognitive stimulation and physical activity. However, we report a high risk of bias for the majority of studies and a low level of quality of evidence. Therefore, further investigations are needed to confirm the efficacy of these interventions and to investigate the possible added benefit on cognition of a combined computerized-cognitive/physical intervention.

ObjectiveTo assess the effectiveness and safety of antibiotic regimens used to treat pelvic inflammatory disease (PID).DesignThis is a systematic review and meta-analysis of randomised controlled trials (RCTs). Risk of bias was assessed using the criteria outlined in the Cochrane guidelines. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation.Data sourcesEight electronic databases were searched from date of inception up to July 2016. Database searches were complemented by screening of reference lists of relevant studies, trial registers, conference proceeding abstracts and grey literature.Eligibility criteriaRCTs comparing the use of antibiotics with placebo or other antibiotics for the treatment of PID in women of reproductive age, either as inpatient or outpatient treatment.ResultsWe included 37 RCTs (6348 women). The quality of evidence ranged from very low to high, the main limitations being serious risk of bias (due to poor reporting of study methods and lack of blinding), serious inconsistency and serious imprecision. There was no clear evidence of a difference in the rates of cure for mild-moderate or for severe PID for the comparisons of azithromycin versus doxycycline, quinolone versus cephalosporin, nitroimidazole versus no use of nitroimidazole, clindamycin plus aminoglycoside versus quinolone, or clindamycin plus aminoglycoside versus cephalosporin. No clear evidence of a difference between regimens in antibiotic-related adverse events leading to discontinuation of therapy was observed.ConclusionsWe found no conclusive evidence that one regimen of antibiotics was safer or more effective than any other for the treatment of PID, and there was no clear evidence for the use of nitroimidazoles (metronidazole) compared with the use of other drugs with activity against anaerobes. More evidence is needed to assess treatments for women with PID, particularly comparing regimens with or without the addition of nitroimidazoles and the efficacy of azithromycin compared with doxycycline.

Background: Herpes zoster is a global public problem that is characterised by a painful blistering rash and unilateral lesions and has a significant negative impact on the quality of patients’ lives. Longdanxiegan Decoction (LDXGD) is a classic herbal formula, and LDXGD combined with valacyclovir is widely used for herpes zoster patients in China. However, evidence-based medicine is not available. Therefore, it is necessary to systematically evaluate the effectiveness of LDXGD combined with valacyclovir in the treatment of herpes zoster, which will provide theoretical support for the treatment of herpes zoster. Objective: This systematic review aimed to explore the effectiveness of LDXGD combined with val-acyclovir for herpes zoster and to compare LDXGD combined with val-acyclovir and val-acyclovir alone. Methods: PubMed, Chinese Scientific Journals Database (VIP), China National Knowledge Infrastructure (CNKI), and Wan-fang Database were searched up to 6 April 2021. Randomised Controlled Trials (RCTs) were identified for herpes zoster treatment involving LDXGD combined with val-acyclovir. The quality of the literature was evaluated using the Cochrane assessment tool to reduce the risk of bias. RevMan 5.4.1 software was used to perform the meta-analysis. Results: Five studies involving 414 participants were identified in this systematic review. Studies were of low to moderate methodological quality based on the risk of bias assessment. The results of our meta-analysis showed the relative benefits of LDXGD combined with valacyclovir in effective rates compared with valacyclovir alone (four studies; P=0.97, I2=0%, OR=4.48, 95%CI [1.89,10.67]), pain intensity (visual analogue scale) (MD: -1.40 mm; 95% CI [-1.89 to -0.92]), The incidence of PHN (RR 0.24; 95% CI [0.10, 0.55]; I2 =0%) and time to crust formation (MD= -1.66 days; 95% CI [2.01,1.30]). The safety of LDXGD combined with valacyclovir remains unclear. Conclusion: Our systematic evaluation provides evidence for the clinical effectiveness and safety of LDXGD combined with valacyclovir for the treatment of herpes zoster. Further trials are necessary to collect evidence for the use of LDXGD. Keywords: Herpes zoster; Longdanxiegan decoction; Valacyclovir; Systematic review; Randomized control trial.

Introduction: Neuroleptics are commonly used drugs to treat different conditions (e.g. psychosis, migraines) in the acute care setting and the emergency department. Their side effects can be disabling or, worse, fatal. The use of diphenhydramine to prevent those side-effects is widespread, but remains controversial. We performed a systematic review to determine if prophylactic administration of diphenhydramine (PAD) reduces the incidence of neuroleptic side-effects. Methods: Data sources: Medline, Embase, Cochrane Library, PsycInfo and Web of Science were searched. References from reviews that were identified in the search and from included studied were also reviewed for inclusion. Study selection: Randomized controlled trials evaluating any neuroleptic with PAD versus the same neuroleptic alone or with any inactive agent. Primary outcome was incidence of any extra-pyramidal side-effect. Secondary outcomes were akathisia, usage of rescue medication, subjective restlessness, neuroleptic malignant syndrome, sedation and sedation intensity. Data extraction: Independent reviewers scanned identified citations, extracted data and assessed for risk of bias. Data analysis: Meta-analysis was performed using random effect models. Heterogeneity and quality of evidence were assessed using, respectively, I2 and the GRADE approach. Results: Results: Of 1566 identified citations, nine studies (n=1436) met all eligibility criteria. Four studies were specifically designed to assess for neuroleptic side-effects. Four studies were at high risk of bias. In primary analysis, PAD had no effect on the incidence of extra-pyramidal symptoms (7 studies, n=1393 patients, RR 0.70 [0.40-1.22]), akathisia (5 studies, n=1094 patients, RR 0.81 [0.36-1.82]) and sedation (5 studies; n=1079, RR 1,48 [0.90-2.42]). Higher dosage of diphenhydramine was not associated with a greater reduction of extra-pyramidal side-effects. In a sensitivity analysis excluding an outlier study (n=120, RR 6.63 [1.55-28,35]), PAD was associated with a significant decrease in extra-pyramidal side-effects (6 studies, n=1273, RR 0.56 [0,38-0.82]), but not with any of the secondary outcome measures. Conclusion: Conclusion: When excluding an outlier study, PAD was associated with a significant reduction of extra-pyramidal side-effects. However, PAD did not significantly influence the incidence of akathisia. Overall quality of evidence is low. Further studies are warranted. PAD represents an interesting treatment option against neuroleptic side-effects, but its widespread usage whitout strong evidence to support it raises concerns.
