Although the majority of people with Covid-19 will experience mild to moderate symptoms and will recover fully, there is now increasing evidence that a significant proportion will experience persistent symptoms for months after the acute phase of the illness. These symptoms include, among others, fatigue, problems breathing, lack of smell and taste, headaches, and depression and anxiety. It is also clear the virus has lasting fluctuating multiorgan sequelae, including affecting not only the respiratory system but also the heart, liver, and nervous system. We present a protocol for a living systematic review that aims to synthesize the evidence on the prevalence and characteristics of post-acute COVID-19. The living systematic review will be updated regularly, approximately every 6 months, as new evidence emerges. We will include studies that follow up at least 100 people with Covid-19 at 12 or more weeks post Covid-19 onset, with no restrictions regarding country, setting, or language. We will use descriptive statistics and, for outcomes reported in two or more studies, we will use meta-analyses to estimate prevalence with 95% confidence intervals (CIs) using the exact method. Heterogeneity between estimates will be assessed using the I2 statistic. Our findings will also be presented as infographics to facilitate transcription to lay audiences. Ultimately, we aim to support the work of policy makers, practitioners, and patients when planning rehabilitation for those recovering from Covid-19. The protocol has been registered with PROSPERO ( CRD42020211131, 25/09/2020).

Although the majority of patients with COVID-19 will experience mild to moderate symptoms and will recover fully, there is now increasing evidence that a significant proportion will experience persistent symptoms for weeks or months after the acute phase of the illness. These symptoms include, among others, fatigue, problems in breathing, lack of smell and taste, headaches, and also depression and anxiety. It has also become clear that the virus has lasting effects not only on the respiratory system but also on other parts of the body, including the heart, liver, and the nervous system. In this paper we present a protocol for a living systematic review that aims to synthesize the evidence on the prevalence and duration of symptoms and clinical features of post-acute COVID-19 and its long-term complications. The living systematic review will be updated regularly, initially monthly with update cycles under continuous review as the pace of new evidence generated develops through the pandemic. We will include studies that follow up with COVID-19 patients who have experienced persistent mild, moderate or severe symptoms, with no restrictions regarding country, setting, or language. We will use descriptive statistics to analyse the data and our findings will be presented as infographics to facilitate transcription to lay audiences. Ultimately, we aim to support the work of policy makers, practitioners, and patients when planning rehabilitation for those recovering from COVID-19.

Background and Aims: Appendectomy is a common surgical procedure, but no overview of the long-term consequences exists. Our aim was to systematically review the long-term complications of appendectomy for acute appendicitis. Materials and Methods: This systematic review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A protocol was registered on PROSPERO (CRD42017064662). The databases PubMed and EMBASE were searched for original reports on appendectomy with n ≥ 500 and follow-up >30 days. The surgical outcomes were ileus and incisional hernia; other outcomes were inflammatory bowel disease, cancer, fertility, and mortality. Results: We included 37 studies. The pooled estimate of the ileus prevalence was 1.0% over a follow-up period of 4.6 (range, 0.5–15) years. Regarding incisional hernia, we found a pooled estimate of 0.7% prevalence within a follow-up period of 6.5 (range, 1.9–10) years. Ulcerative colitis had a pooled estimate of 0.15% prevalence in the appendectomy group and 0.19% in controls. The opposite pattern was found regarding Crohn’s disease with a pooled estimate of 0.20% prevalence in the appendectomy group and 0.12% in controls. No clear pattern was found regarding most of the examined cancers in appendectomy groups compared with background populations. Pregnancy rates increased after appendicitis compared with controls in most studies. Mortality was low after appendectomy. Conclusion: Appendectomy had a low prevalence of long-term surgical complications. We did not find any significant other long-term complications, though the prevalence of Crohn’s disease was higher and the prevalence of ulcerative colitis was lower after appendectomy than in controls. Appendectomy did not impair fertility.

Objective: Both true and false extracranial carotid artery aneurysms (ECAA) are a potential source of morbidity and mortality. While ECAA have historically been treated surgically, endovascular reconstruction with stenting is an emerging treatment option. The aim of our study was to report clinical/radiologic outcomes following endovascular repair of ECAAs. Methods: A comprehensive systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Results: A total of 68 case reports and case series, comprising 162 patients, were included. Most patients presented with at least one symptom or sign related to the ECAA (89.5%; N = 145/162). In 42.6% (N = 69/162) and 46.3% (N = 75/162) of the cases polytetrafluoroethylene covered and uncovered stents were deployed respectively. Immediate post-procedural imaging demonstrated complete aneurysm exclusion in 86.4% (N = 140/162) of the cases and minimal filling of the aneurysm sack in 10.5% (N = 17/162) of all cases. Perioperative adverse event rates were 3.1% for stroke, 1.2% for transient ischemic attack (TIA) and 4.3% for mortality. During a mean follow-up of 21.8months, there were additionally observed one stroke, two TIAs and three deaths. Overall 88.6 % of the patients (N = 117/132) remained asymptomatic, partially recovered or at least did not suffer from new neurologic deficits during follow up, with no signs of stenosis or occlusion of the carotid artery. Conclusions: Endovascular stenting for the treatment of ECAAs is feasible with acceptable short- and long-term clinical and radiologic outcomes. Prospective real-world studies are needed to further validate the safety and the long-term patency of endovascular repair.

ObjectiveTo identify randomised controlled trials (RCTs) of physical activity (PA) interventions with objective PA outcomes in adults and to evaluate whether intervention effects were sustained beyond 12 months.DesignSystematic review and meta-analysis.Data sourcesSeven databases (Medline, Embase, PsycINFO, Web of Science, Cochrane library, CINAHL (Cumulative Index of Nursing and Allied Health Literature) and ASSIA (Applied Social Sciences Index and Abstracts)) were searched from January 2000 until December 2019.Eligibility criteriaRCTs reporting objective PA outcomes beyond 12 months with community-based participants aged ≥18 years were included; those where controls received active interventions, including advice to increase PA levels, were excluded.Data extraction and synthesisTwo independent reviewers completed extraction of aggregate data and assessed risk of bias. Meta-analyses used random-effects models at different follow-up points. Primary outcomes were daily steps and weekly minutes of moderate-to-vigorous PA (MVPA).ResultsOf 33 282 records identified, nine studies (at generally low risk of bias) were included, five in meta-analyses with 12 months to 4 year follow-up. We observed 12 month increases for intervention vs control participants in steps/day (mean difference (MD)=554 (95% CIs: 384 to 724) p<0.0001, I2=0%; 2446 participants; four studies) and weekly MVPA minutes (MD=35 (95% CI: 27 to 43) p<0.0001, I2=0%; 2647 participants; four studies). Effects were sustained up to 4 years for steps/day (MD=494 (95% CI: 251 to 738) p<0.0001, I2=0%; 1944 participants; four studies) and weekly MVPA minutes (MD=25 (95% CI: 13 to 37) p<0.0001, I2=0%; 1458 participants; three studies).ConclusionsThere are few PA interventions with objective follow-up beyond 12 months, more studies are needed. However, this review provided evidence of PA intervention effects beyond 12 months and sustained up to 4 years for both steps/day and MVPA. These findings have important implications for potential long-term health benefits.PROSPERO registration numberCRD42017075753.

Background: The success of repeat surgery for recurrent trigeminal neuralgia (TN)—with microvascular decompression (MVD), percutaneous rhizotomy (PR), or stereotactic radiosurgery (SRS)—is not well-studied. We performed a systematic review and meta-analysis of the literature on repeat surgery recurrent TN, focusing on the durability of pain relief and relative efficacy of MVD, PR, and SRS. Methods: A PRISMA systematic review of Medline/Embase/Pubmed identified studies of adults with unilateral idiopathic TN undergoing repeat surgery. The primary outcome of complete pain relief (CPR) at last follow-up was analyzed with a multivariate mixed-effects meta-analysis of proportions. Results: Seventy-eight studies met criteria; 61 were included in meta-analyses, containing 29/14/25 cohorts with 900/684/1353 patients undergoing MVD/PR/SRS respectively (mean age 64.7 years, 41% males). Initial CPR was 69% (74%/85%/52%). CPR at mean 39.7 month follow-up (38.3/38.8/41.0) was 48% (59%/60%/34%). Initial CPR for both MVD (CPR: 0.78 [0.70-0.85]) and PR (CPR: 0.93 [0.83-0.98]) was superior to SRS (CPR: 0.48 [0.35-0.61]). At follow-up, MVD (0.45 [0.32-0.58]) and PR (0.45 [0.30-0.60]) trended towards superior CPR versus SRS (0.25 [0.15-0.37]). Conclusions: Half of recurrent TN patients achieve good pain control 3 years after repeat surgery. MVD/PR showed superior initial pain relief and likely better long-term relief. These findings can inform surgical decision-making in this challenging population.

Background: Lockdown measures implemented to contain the Covid-19 virus have increased health inequalities, with families from deprived and ethnically diverse backgrounds most likely to be adversely affected. This paper describes the experiences of families living in the multi-ethnic and deprived city of Bradford, England. Methods: A wave of survey data collection using a combination of email, text and phone with postal follow-up during the first Covid-19 UK lockdown (10th April to 30th June 2020) with parents participating in two longitudinal studies. Cross tabulations explored variation by ethnicity and financial insecurity. Text from open questions was analysed using thematic analysis. Results: Of 7,652 families invited, 2,144 (28%) participated. The results presented are based on the 2,043 (95%) mothers’ responses: 957 (47%) of whom were of Pakistani heritage, 715 (35%) White British and 356 (18%) other ethnicity 971 (46%) lived in the most deprived decile of material deprivation in England. and 738 (37%) were financially insecure. Many families lived in poor quality (N=574, 28%), overcrowded (N=364, 19%) housing. Food (N=396, 20%), employment (N=728, 37%) and housing (N=204, 10%) insecurities were common, particularly in those who were furloughed, self-employed not working or unemployed. Clinically important depression and anxiety were reported by 372 (19%) and 318 (16%) mothers. Ethnic minority and financially insecure families had a worse experience during the lockdown across all domains, with the exception of mental health which appeared worse in White British mothers.  Open text responses corroborated these findings and highlighted high levels of anxiety and fear about Covid-19. Conclusions: There is a need for policy makers and commissioners to better support vulnerable families during and after the pandemic. Future work will use longitudinal data from before the pandemic, and from future surveys during the pandemic, to describe trajectories and the long-term consequences of the pandemic on vulnerable populations.

Abstract Introduction: While several previous meta-analyses have documented the short-term efficacy of cognitive-behavioral therapy (CBT), its long-term efficacy remains unknown. Posttraumatic stress disorder (PTSD) is a serious, debilitating, often chronic and disabling disease. Objective: To estimate the long-term efficacy of CBT in the treatment of PTSD by assessing the maintenance of the effect after one year of follow-up. Method: We performed a systematic review through electronic database searches including ISI Web of Science, PubMed, PsycInfo and Pilots. We included randomized studies in which CBT was compared with a control group (waiting list or usual care) in adults with PTSD that reported at least one year of CBT follow-up. Results: Our search identified 2,324 studies and 8 were selected. CBT was shown to be effective in the treatment of PTSD in the post-treatment period. Improvement in PTSD symptoms was statistically significant in relation to the control group. The improvement observed in the treatment group or single group (formed by both treatment group and control group, which was submitted to the intervention after a few weeks on the waiting list) was maintained in the follow-up. Conclusion: Due to the lack of control groups in the follow-up period in six of the eight studies included in this review, there is still no proper methodological basis to assert that CBT has lasting effects in the treatment of PTSD. Our study found serious methodological shortcomings and the need to fill this gap in the literature through the development of studies with robust and sophisticated designs.

Introduction The Nellix endovascular aneurysm sealing (EVAS) system has been a topic of discussion. Early results were promising but did not deliver on the long-term and the device has been recalled from the market. This study compares literature for EVAS and conventional endovascular aneurysm repair (EVAR). Methods A systematic review and analysis was conducted according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. PubMed, Embase, and Cochrane Library were searched and identified the eligible studies. Proportion rates for the outcomes of interest were extracted. Subgroup analyses were performed for EVAS and EVAR. Results A total of 12 studies were included (EVAS n = 4, EVAR n = 8) including 10,255 patients (EVAS n = 784, EVAR n = 9441). The longest duration of follow-up was 3.4 years for EVAS and 5.0 years for EVAR studies. Throughout follow-up the overall all-cause mortality rates were 6% for EVAS and 13% for EVAR, and endoleak of any type was described in 10% of EVAS and 17% of EVAR patients. The migration rate >10 mm was 8% for EVAS and 0% for EVAR and aneurysm growth >5 mm was found in 11% of EVAS and 3% of EVAR cases. Total reintervention rate was 13% for EVAS and 7% for EVAR patients. For all analyzed outcome parameters heterogeneity was >50%. Conclusion There is a tendency toward lower mortality and overall endoleak rates for EVAS compared to EVAR but with a higher rate of migration, aneurysm growth, and reintervention. Despite lower overall endoleak rates there was a tendency toward less type II and more type I endoleaks after EVAS compared to EVAR. Substantial heterogeneity however limits robust statistical analyses, and is probably caused by significant instructions for use breach in EVAS-treated patients. We call for more high-quality and long-term follow-up studies on both EVAS and EVAR in order to confirm the trends found in this study.

OBJECTIVEThe role of mechanical thrombectomy in pediatric acute ischemic stroke is uncertain, despite extensive evidence of benefit in adults. The existing literature consists of several recent small single-arm cohort studies, as well as multiple prior small case series and case reports. Published reports of pediatric cases have increased markedly since 2015, after the publication of the positive trials in adults. The recent AHA/ASA Scientific Statement on this issue was informed predominantly by pre-2015 case reports and identified several knowledge gaps, including how young a child may undergo thrombectomy. A repeat systematic review and meta-analysis is warranted to help guide therapeutic decisions and address gaps in knowledge.METHODSUsing PRISMA-IPD guidelines, the authors performed a systematic review of the literature from 1999 to April 2019 and individual patient data meta-analysis, with 2 independent reviewers. An additional series of 3 cases in adolescent males from one of the authors’ centers was also included. The primary outcomes were the rate of good long-term (mRS score 0–2 at final follow-up) and short-term (reduction in NIHSS score by ≥ 8 points or NIHSS score 0–1 at up to 24 hours post-thrombectomy) neurological outcomes following mechanical thrombectomy for acute ischemic stroke in patients < 18 years of age. The secondary outcome was the rate of successful angiographic recanalization (mTICI score 2b/3).RESULTSThe authors’ review yielded 113 cases of mechanical thrombectomy in 110 pediatric patients. Although complete follow-up data are not available for all patients, 87 of 96 (90.6%) had good long-term neurological outcomes (mRS score 0–2), 55 of 79 (69.6%) had good short-term neurological outcomes, and 86 of 98 (87.8%) had successful angiographic recanalization (mTICI score 2b/3). Death occurred in 2 patients and symptomatic intracranial hemorrhage in 1 patient. Sixteen published thrombectomy cases were identified in children < 5 years of age.CONCLUSIONSMechanical thrombectomy may be considered for acute ischemic stroke due to large vessel occlusion (ICA terminus, M1, basilar artery) in patients aged 1–18 years (Level C evidence; Class IIb recommendation). The existing evidence base is likely affected by selection and publication bias. A prospective multinational registry is recommended as the next investigative step.
