Varicose Vein Education and Informed coNsent (VVEIN) Study: A Randomized Controlled Pilot Feasibility Study.

BACKGROUND: The primary aim of this study was to assess the feasibility of introducing a digital health education tool (dHET) for varicose vein surgery. METHODS: This randomized, feasibility study allocated 40 patients, into dHET (n = 20) or standard consent (SC) (n = 20) groups. Primary outcomes were related to feasibility. Secondary outcomes were knowledge recall, anxiety, and satisfaction. RESULTS: Recruitment and retention rates were 100% and 97.5%, respectively. Acceptability was also rated high, confirming feasibility. There was also no evidence of a difference between groups for early knowledge recall (14 [12-17] vs. 14 [11-16]; P = 0.72) or delayed (at 2 weeks) knowledge recall (15 [13-16] vs. 15 [13-16]; P = 0.89). The dHET module took significantly longer to complete compared to SC (13 min [12-18] vs. 9 min [8-12]; P < 0.01). However, the control group asked significantly more questions about the intended procedure (P = 0.03). There was no evidence of a difference between groups for patient anxiety or satisfaction. CONCLUSIONS: This trial shows that the addition of a dHET is feasible and noninferior to SC. Digital consent provides a unique opportunity to promote patient education and autonomy for better shared decision making. It also offers better documentation of the consent process.

Varicose Vein Education and Informed coNsent (VVEIN) study: a randomised controlled pilot feasibility study.

INTRODUCTION: Doctors have a legal requirement and duty of care to ensure patients are enabled to make an informed decision about their treatment, including discussion of the benefits, risks and alternatives to a procedure. A patient-centred approach to consent has been firmly established in Ireland, and fundamental to this is the ability to engage in a dialogue that offers comprehensible information to patients. Telemedicine has revolutionised the way we can deliver care to patients in the modern era of computers, tablets, and smartphones, and its use has been rapidly expanded. Novel digital strategies to improve the informed consent process for surgical procedures have been increasingly under investigation over the last 10-15 years and may offer a low cost, accessible and tailored solution to consent for surgical interventions. Within vascular surgery, superficial venous interventions have been associated with a high number medicolegal claims and also represents an area within the specialty with rapidly evolving technology and techniques. The ability to communicate comprehensible information to patients has never been greater. Thus, the author's aim is to explore whether it is feasible and acceptable to deliver a digital health education intervention to patients undergoing endovenous thermal ablation (EVTA) to supplement the consent process. METHODS: This is a prospective, single centre, randomised controlled, feasibility trial recruiting patients with chronic venous disease deemed suitable to undergo EVTA. Patients will be randomised to receive either standard consent (SC) or a newly developed digital health education tool (dHET). The primary outcome is feasibility; assessing the recruitment and retention rate of participants and assessing acceptability of the intervention. Secondary outcomes include knowledge retention, anxiety and satisfaction. This feasibility trial is designed to recruit 40 patients, which will allow for a moderate dropout rate. This pilot study will inform the authors of the appropriateness of an adequately powered multicentre trial. DISCUSSION: To examine the role of a digital consent solution for EVTA. This may improve and standardise the consent dialogue with patients and may have the potential to reduce claims related to poor consent processes and disclosure of risks. ETHICAL COMMITTEE REFERENCE: Ethical approval has been sought and received from both the Bon Secours Hospital and RCSI (202109017), on 14 May 2021 and 10 October 2021, respectively.

Is the public ready for a tobacco-free Ireland? A national survey of public knowledge and attitudes to tobacco endgame in Ireland.

AIM: Ireland will not meet the tobacco endgame goal set in its 2013 Tobacco-Free Ireland (TFI) policy of reducing smoking prevalence to less than 5% by 2025. Public opinion on tobacco endgame, a key lever to realise this goal, is uncharted in Ireland. This study aimed to measure public knowledge and attitudes to tobacco endgame. METHODS: A telephone-administered cross-sectional survey of 1000 randomly dialled members of the general public was conducted in 2022. Prevalence of awareness, perceived achievability and support for the TFI goal and tobacco endgame measures was calculated and compared across tobacco product use status. Logistic regression identified factors independently associated with goal support. FINDINGS: Although TFI goal awareness was low (34.0%), support was high (74.6%), although most (60.2%) believed it achievable beyond 2025. Product-focused measures were popular while support for supply-focused measures was mixed: for example, 86.1% supported nicotine content reduction while 40.3% supported user licencing. Phasing out tobacco sales was highly supported (82.8%); for most, this was contingent on support for currently addicted users. TFI goal support was independently associated with female sex (adjusted odds ratio (aOR) 1.47, 95% CI 1.05 to 2.07), higher education (aOR 1.80, 95% CI 1.21 to 2.66) and non-tobacco product use (aOR 2.67, 95% CI 1.66 to 4.30). CONCLUSIONS: Despite low awareness, tobacco endgame support is strong in Ireland. Public appetite for radically reducing tobacco product appeal and availability combined with public views on endgame achievability subject to extended timelines should be used to re-invigorate tobacco endgame discussion and planning in countries at risk of failing to meet declared targets.

Public attitudes to implementing financial incentives in stopsmoking services in Ireland.

INTRODUCTION: Financial incentives improve stop-smoking service outcomes. Views on acceptability can influence implementation success. To inform implementation planning in Ireland, public attitudes on financial incentives to stop smoking were measured. METHODS: A cross-sectional telephone survey was administered to 1000 people in Ireland aged ≥15 years in 2022, sampled through random digit dialing. The questionnaire included items on support for financial incentives under different conditions. Prevalence of support was calculated with 95% Confidence Intervals (CIs) and multiple logistic regression identified associated factors using adjusted odds ratios (AORs) with 95% CIs. RESULTS: Almost half (47.0%, 95% CI: 43.9-50.1) of the participants supported at least one type of financial incentive to stop smoking, with support more prevalent for shopping vouchers (43.3%, 95% CI: 40.3-46.5) than cash payments (32.1%, 95% CI: 29.2-35.0). Support was similar for universal and income-restricted schemes. Of those who supported financial incentives, the majority (60.6%) believed the maximum amount given on proof of stopping smoking should be under €250 (median=100, range: 1-7000). Compared to their counterparts, those of lower education level (AOR=1.49; 95% CI: 1.10-2.03, p=0.010) and tobacco/e-cigarette users (AOR=1.43; 95% CI: 1.02-2.03, p=0.041) were significantly more likely to support either financial incentive type, as were younger people. CONCLUSIONS: While views on financial incentives to stop smoking in Ireland were mixed, the intervention is more acceptable in groups experiencing the heaviest burden of smoking-related harm and most capacity to benefit. Engagement and communication must be integral to planning for successful implementation to improve stop-smoking service outcomes.

A modified Delphi process to form an expert consensus in Ireland on the essential information to be included in shared decision making for varicose vein surgery.

OBJECTIVE: To reach consensus on a core set of essential information for inclusion in the informed consent process to standardize consent for VV surgery. METHODS: Using a modified electronic Delphi (e-Delphi) method, a panel of experts in Ireland, were asked to rate statements of essential information to include in the informed consent process with patients. Statements were rated using a 5-point Likert scale. The definition of consensus was declared at 70% agreement by the panel. RESULTS: Twenty-three panel members accepted the invitation to participate across three e-Delphi rounds. Consensus was reached on 33/42 statements, covering general and procedural information and the risks, benefits and alternatives of varicose veins (VV) surgery. Several statements remained equivocal, having not met consensus by the panel. CONCLUSION: Considerable consensus was reached within the panel of experts but some gaps in available research were also highlighted. This consensus may provide the framework to aid physicians to deliver a standardized discussion of the key elements of consent and shared decision making with patients.

Digital technology in informed consent for surgery: systematic review.

BACKGROUND: Informed consent is an ethical and legal requirement in healthcare and supports patient autonomy to make informed choices about their own care. This review explores the impact of digital technology for informed consent in surgery. METHODS: A systematic search of EBSCOhost (MEDLINE/CINAHL), Embase, Cochrane Central Register of Controlled Trials and Web of Science was performed in November 2021. All RCTs comparing outcomes of both digital and non-digital (standard) consent in surgery were included. Each included study underwent an evaluation of methodological quality using the Cochrane risk of bias (2.0) tool. Outcomes assessed included comprehension, level of satisfaction and anxiety, and feasibility of digital interventions in practice. RESULTS: A total of 40 studies, across 13 countries and 15 surgical specialties were included in this analysis. Digital consent interventions used active patient participation and passive patient participation in 15 and 25 studies respectively. Digital consent had a positive effect on early comprehension in 21 of 30 (70 per cent) studies and delayed comprehension in 9 of 20 (45 per cent) studies. Only 16 of 38 (42 per cent) studies assessed all four elements of informed consent: general information, risks, benefits, and alternatives. Most studies showed no difference in satisfaction or anxiety. A minority of studies reported on feasibility of digital technology in practice. CONCLUSION: Digital technologies in informed consent for surgery were found to have a positive effect on early comprehension, without any negative effect on satisfaction or anxiety. It is recommended that future studies explore the feasibility of these applications for vulnerable patient groups and busy surgical practice.

Effective maNagement of depression among patients witH cANCEr (ENHANCE): a protocol for a hybrid systematic review and network meta-analysis of randomised controlled trials of interventions for depressive symptoms.

BACKGROUND: Depression is common among patients with cancer and is associated with lower treatment participation, lower satisfaction with care, poorer quality of life, greater symptom burden and higher healthcare costs. Various types of interventions (e.g. pharmacological, psychotherapy) are used for the treatment of depression. However, evidence for these among patients with cancer is limited. Furthermore, the relative effectiveness and acceptability of different approaches are unknown because a direct comparison between all available treatments has not been carried out. We will address this by conducting a network meta-analysis (NMA) of interventions for depression among people with cancer using a hybrid overview of reviews and systematic review methodology. METHODS: We will search for and extract data from systematic reviews of randomised controlled trials (RCTs) of depression interventions for patients with cancer from inception, before performing a supplemental search for more recent RCTs. We will include RCTs comparing pharmacological, psychotherapy, exercise, combination therapy, collaborative care or complementary and alternative medicine interventions with pill placebo, no treatment, waitlist, treatment as usual or minimal treatment control groups, or directly in head-to-head trials, among adults who currently have cancer or have a history of any cancer and elevated depressive symptoms (scores above a cut-off on validated scales or meeting diagnostic criteria). Our primary outcomes will be change in depressive symptoms (standardised mean difference) and intervention acceptability (% who withdrew). Our secondary outcomes will be 6-month change in depressive symptoms, health-related quality of life, adverse events and mortality. We will independently screen for eligibility, extract data and assess risk of bias using the RoB 2 tool. We will use frequentist random-effects multivariate NMA in Stata, rankograms and surface under the cumulative ranking curves to synthesise evidence and obtain a ranking of intervention groups. We will explore heterogeneity and inconsistency using local and global measures and evaluate the credibility of results using the Confidence in NEtwork Meta-Analysis (CINeMA) framework. DISCUSSION: Our findings will provide the best available evidence for managing depression among patients with cancer. Such information will help to inform clinical guidelines, evidence-based treatment decisions and future research by identifying gaps in the current literature.

Mixed methods evaluation of the 'real-world' implementation of group-based behavioral stop smoking support through Facebook.

INTRODUCTION: While promising evidence from trials of social-media-based stop smoking support informs service-planning, there is a need for more prospective, observational studies of smoking cessation interventions to build 'real-world' evidence. Specifically, user experiences have been under-explored with qualitative methods to date. This mixed-method evaluation of a closed Facebook group-based behavioral stop smoking support program, which was conducted in Ireland in 2018, aimed to address these issues. METHODS: Pre- and post-program surveys measured smoking abstinence (self-reported 7-day point prevalence), changes in smoking attitudes and behavior, and participant experiences. Engagement with Facebook was measured through counting 'likes' and comments, and was used to categorize groups as 'more active' and 'less active' over a 12-week period of support. Thematic content analysis of semi-structured participant interviews explored program experience in depth. RESULTS: In total, 13 of 52 participants reported smoking abstinence post-program (25.0%, 95% CI: 14.0-39.0). Participant engagement with Facebook was variable and decreased over the program. Membership of a 'more active' group was associated with better reported participant experience (e.g. 90.9% agreeing 'Facebook group helped me to quit or reduce smoking', versus 33.3% in the 'less active' group, p<0.05). Qualitative analysis identified three over-arching themes: importance of social interactions; perception of health information; and appeal of online support. CONCLUSIONS: Facebook can be used to deliver group-based behavioral stop smoking support in the real world. In Ireland, the one-month post-program abstinence outcomes achieved by other stop smoking services is approximately 50%, and while the outcomes for this service was lower (25%), it is still better than outcomes estimated for unassisted quitting. Engagement and peer-to-peer interactivity should be maximized to support positive participant experience.

Safety, efficacy, and cost-effectiveness of minimally invasive esophagectomies versus open esophagectomies: an umbrella review.

Traditionally, esophageal oncological resections have been performed via open approaches with well-documented levels of morbidity and mortality complicating the postoperative course. In contemporary terms, minimally invasive approaches have garnered sustained support in all areas of surgery, and there has been an exponential adaptation of this technology in upper GI surgery with the advent of laparoscopic and robotic techniques. The current literature, while growing, is inconsistent in reporting on the benefits of minimally invasive esophagectomies (MIEs) and this makes it difficult to ascertain best practice. The objective of this review was to critically appraise the current evidence addressing the safety, efficacy, and cost-effectiveness of MIEs versus open esophagectomies. A systematic review of the literature was performed by searching nine electronic databases to identify any systematic reviews published on this topic and recommended Joanna Briggs Institute approach to critical appraisal, study selection, data extraction and data synthesis was used to report the findings. A total of 13 systematic reviews of moderate to good quality encompassing 143 primary trials and 36,763 patients were included in the final synthesis. Eleven reviews examined safety parameters and found a generalized benefit of MIE. Efficacy was evaluated by eight systematic reviews and found each method to be equivalent. There were limited data to judiciously appraise cost-effectiveness as this was only evaluated in one review involving a single trial. There is improved safety and equivalent efficacy associated with MIE when compared with open esophagectomy. Cost-effectiveness of MIE cannot be sufficiently supported at this point in time. Further studies, especially those focused on cost-effectiveness are needed to strengthen the existing evidence to inform policy makers on feasibility of increased assimilation of this technology into clinical practice.

Thoracolumbar Burst Fractures: A Systematic Review and Meta-Analysis Comparing Posterior-Only Instrumentation Versus Combined Anterior-Posterior Instrumentation.

STUDY DESIGN: Meta-analysis. OBJECTIVE: To compare the clinical, functional, and radiological outcomes of posterior-only versus combined anterior-posterior instrumentation in order to determine the optimal surgical intervention for thoracolumbar burst fractures. SUMMARY OF BACKGROUND DATA: Unstable thoracolumbar burst fractures warrant surgical intervention to prevent neurological deterioration and progressive kyphosis, which can lead to significant pain and functional morbidity. The available literature remains largely inconclusive in determining the optimal instrumentation strategy. METHODS: Electronic searches of MEDLINE (1948-May 2020), EMBASE (1947-May 2020), The Cochrane Library (1991-May 2020), and other databases were conducted. Cochrane Collaboration guidelines were used for data extraction and quality assessment. Outcomes of interest were divided into three categories: radiological (degree of postoperative kyphosis correction; loss of kyphosis correction at final follow-up), functional (visual analogue scale [VAS] pain score; Oswestry Disability Index [ODI] score), and clinical (intraoperative blood loss; length of stay [LOS]; operative time; the number and type of postoperative complications). RESULTS: Four randomized control trials (RCTs) were retrieved, including 145 randomized participants. Seventy-three patients underwent posterior-only instrumentation and 72 underwent combined instrumentation. No significant difference was found in the degree of postoperative kyphosis correction (P = 0.39), VAS (centimeters) at final follow-up (P = 0.67), ODI at final follow-up (P = 0.89) or the number of postoperative complications between the two approaches (P = 0.49). Posterior-only instrumentation was associated with lower blood loss (P < 0.001), operative time (P < 0.001), and LOS (P = 0.01). Combined instrumentation had a lower degree of kyphosis loss at final follow-up (P = 0.001). There was heterogeneity in the duration of follow-up between the included studies (mean follow-up range 24-121 months). CONCLUSION: The available literature remains largely inconclusive. In order to reliably inform practice in this area, there is a need for large, high-quality, multicenter RCTs with standardized reporting of outcomes, with a particular focus on outcomes relating to patient function and severe complications causing long-term morbidity.Level of Evidence: 2.

E-Cigarette-Only and Dual Use among Adolescents in Ireland: Emerging Behaviours with Different Risk Profiles.

E-cigarette-only use and dual-use are emerging behaviours among adolescent nicotine product users which have not yet been sufficiently explored. This study examines the prevalence of, and the factors associated with, nicotine product use in adolescence. The study is a cross-sectional analysis of the 2018 Planet Youth survey completed by 15-16 year olds in the West of Ireland in 2018. The outcome of interest was current nicotine product use, defined as use at least once in the past 30 days. A main effects multinomial logistic regression model was used to examine the association between potential risk and protective factors and nicotine product use. Among 4422 adolescents 22.1% were current nicotine product users, consisting of 5.1% e-cigarette only users, 7.7% conventional cigarette only users, and 9.3% dual-users. For risk factors, the odds of association were weaker for e-cigarette only use compared to conventional cigarette and dual use. Participating in team sport four times/week or more significantly reduced the odds of conventional cigarette and dual use but had no association with e-cigarette only use (Cig: adjusted odds ratio (AOR) 0.63, 95% confidence interval (CI) 0.44-0.90; Dual-use: AOR 0.63, 95% CI 0.43-0.93). Similarly, having higher value for conventional social norms reduced the odds of conventional cigarette and dual use but not e-cigarette only use. This is the first study to show, among a generalisable sample, that dual-use is the most prevalent behaviour among adolescent nicotine product users in Ireland. Risk factor profiles differ across categories of use and prevention initiatives must be cognisant of this.

Prospective study of provided smoking cessation care in an inpatient psychiatric setting.

OBJECTIVE: People with mental health difficulties (MHD) are more likely to smoke and to have smoking-related diseases, yet little research has investigated the provision of smoking cessation care in psychiatric inpatient settings. This study aimed to evaluate current levels of cessation care provided, and 3-month quit-rates, in one such setting in Ireland. METHODS: From January to October 2016, inpatients across all 8 adult wards of St Patrick's University Hospital were recruited to participate in a baseline face-to-face survey (N = 246), assessing demographic information, smoking history and quit attempts, motivation to quit, nicotine dependence, attitudes towards cessation advice and actual care received. For baseline current smokers (n = 84) who consented, casenotes were also audited for documentation of smoking status and cessation care (n = 77/84) while quit rates were assessed at three months (n = 72/84), including a carbon monoxide test for those who reported quitting. RESULTS: Current smoking prevalence was 34% (n = 84/246). At baseline 75% of smokers wanted to quit and 48% reported they would like cessation advice while in hospital. Few reported receiving cessation advice from any healthcare professional in the past year (13%), while just 6% had smoking cessation care clearly documented in their casenotes. The 3-month quit-rate was 17%, with a 100% pass rate for those completing an objective CO validation test. CONCLUSION: Despite a high current smoking prevalence among psychiatric inpatients, and similar motivation and quit rates to other populations, current cessation care rates are low. Smoking cessation care needs to be prioritised in psychiatric settings.

Implementation of a Quit Smoking Programme in Community Adult Mental Health Services-A Qualitative Study.

Little is known about the experiences of people with severe mental health difficulties in smoking cessation interventions. This study aimed to review the implementation of a smoking cessation programme across 16 community mental health day services. The aim was to establish the experience from both service user and facilitator perspectives and refine implementation for future groups. In-depth interviews were conducted with 20 service users and four focus groups held with 17 facilitators. Thematic analysis was used to analyse the data for emergent themes in relation to key enablers and barriers to implementation. Data from service users and facilitators revealed that implementation was enabled by an open and engaged recruitment approach; the resourcefulness of facilitators; programme materials and group-based format; combining the cessation programme with other and broader health initiatives; and participants' motivations, including health and money. Barriers included the structure of the service; the lack of a joined-up approach across the health services; literacy issues and the serial/logical process assumed by the programme. Barriers perceived as more specific to those with mental health difficulties included the use of smoking as a coping mechanism, lack of alternative activities/structure and lack of consistent determination. The tobacco free policy, implemented shortly before the programme, interestingly emerged as both a barrier and an enabler. In conclusion, although this group-based cessation programme in community mental health settings was well-received overall, a number of key barriers persist. A joined-up approach which addresses the culture of smoking in mental health settings, inconsistencies in smoking policies, and provides consistent cessation support, is needed. Care needs to be taken with the timing as overall it may not be helpful to introduce a new smoking cessation programme at the same time as a tobacco free policy.

Medical student INtervention to promote effective nicotine dependence and tobacco HEalthcare (MIND-THE-GAP): single-centre feasibility randomised trial results.

BACKGROUND: Although brief cessation advice from healthcare professionals increases quit rates, smokers typically do not get this advice during hospitalisation, possibly due to resource issues, lack of training and professionals' own attitudes to providing such counselling. Medical students are a potentially untapped resource who could deliver cessation counselling, while upskilling themselves and changing their own attitudes to delivering such advice in the future; however, no studies have investigated this. We aimed to determine if brief student-led counselling could enhance motivation to quit and smoking cessation behaviours among hospitalised patients. METHODS: A mixed-methods, 2-arm pilot feasibility randomised controlled trial with qualitative process evaluation enrolled 67 hospitalised adult smokers, who were recruited and randomized to receive a brief medical student-delivered cessation intervention (n = 33) or usual care (n = 34); 61 medical students received standardised cessation training and 33 were randomly assigned to provide a brief in-hospital consultation and follow-up support by phone or in-person one week post-discharge. Telephone follow-up at 3- and 6-months assessed scores on the Motivation to Stop Smoking Scale (MTSS; primary outcome) and several other outcomes, including 7-day point prevalent abstinence, quit attempts, use of cessation medication, and ratings of student's knowledge and efficacy. Data were analysed as intention to treat (ITT) using penalised imputation, per protocol, and random effects repeated measures. Focus group interviews were conducted with students post-intervention to elicit their views on the training and intervention process. RESULTS: Analyses for primary and most secondary outcomes favoured the intervention group, although results were not statistically significant. Point prevalence abstinence rates were significantly higher for the intervention group during follow-up for all analyses except 6-month ITT analysis. Fidelity was variable. Patients rated students as being "very" knowledgeable about quitting and "somewhat" helpful. Qualitative results showed students were glad to deliver the intervention; were critical of current cessation care; felt constrained by their inability to prescribe cessation medications and wanted to include cessation and other behavioural counselling in their normal history taking. CONCLUSIONS: It appears feasible for medical students to be smoking cessation interventionists during their training, although their fidelity to the intervention requires further investigation. A definitive trial is needed to determine if medical students are effective cessation counsellors and if student-led intervention could be tailored for other health behaviours. TRIAL REGISTRATION: NCT02601599 (retrospectively registered 1 day after first participant recruited on November 3rd 2015).

Exploring smoking, mental health and smoking-related disease in a nationally representative sample of older adults in Ireland - A retrospective secondary analysis.

OBJECTIVE: Smoking is the leading preventable cause of death among individuals with mental health difficulties (MHD). The aim of the current study was to determine the impact of smoking on the physical health of older adults with MHD in Ireland and to explore the extent to which smoking mediated or moderated associations between MHD and smoking-related diseases. METHODS: Cross-sectional analysis of a nationally representative sample of 8175 community-dwelling adults aged 50 and over from The Irish Longitudinal Study on Ageing (TILDA) was undertaken. Multivariate adjusted logistic regression models were used to assess the association between MHD, smoking (current/past/never) and smoking-related diseases (respiratory disease, cardiovascular disease, smoking-related cancers). A number of variables were employed to identify individuals with MHD, including prescribed medication, self-reported diagnoses and self-report scales. RESULTS: MHD was associated with current (RRRs ranging from 1.84 [1.50 to 2.26] to 4.31 [2.47 to 7.53]) and former (RRRs ranging from 1.26 [1.05 to 1.52] to 1.99 [1.19 to 3.33]) smoking and also associated with the presence of smoking-related disease (ORs ranging from 1.24 [1.01 to 1.51] to 1.62 [1.00 to 2.62]). Smoking did not mediate and rarely moderated associations between MHD and smoking-related disease. CONCLUSIONS: Older adults in Ireland with MHD are more likely to smoke than those without such difficulties. They also experience higher rates of smoking-related disease, although smoking had no mediating and no consistent moderating role in these analyses. Findings underscore the need for attention to the physical health of those with MHD including support in smoking cessation.

Cross-linking in children with keratoconus: a systematic review and meta-analysis.

Keratoconus can behave more aggressively in pediatric than in adult patients. We systematically reviewed the literature to determine the effectiveness of corneal collagen cross-linking (CXL) in children. For this study, MEDLINE® and Cochrane databases were searched for all studies examining the effects of standard, trans-epithelial or accelerated CXL protocols in patients age 18 years or younger. Primary outcomes were; uncorrected visual acuity (UCVA) and maximum keratometry (Kmax) and secondary outcomes were; best-corrected visual acuity (BCVA), mean refractive spherical equivalent (MRSE), central corneal thickness (CCT) and endothelial cell density (ECD). Standardized mean differences (SMD) and 95% confidence intervals were calculated, comparing baseline values with those at 6, 12 and 24 months. A total of 13 papers, published between May 2011 and December 2014 examining 490 eyes of 401 patients with a mean age of 15.25 (±1.5) years, were included in the qualitative analysis in this review. Nine papers were included in the meta-analysis, showing significant improvement in UCVA and BCVA and stable Kmax at 12 months, and stable UCVA, improved BCVA and improved Kmax at 24 months in the standard protocol group UCVA, BCVA and KMax were stable at 12 months in the trans-epithelial group. Mean refractive spherical equivalent (MRSE), CCT and ECD remained stable in both groups. In conclusion it was found that standard CXL may be effective in halting progression of keratoconus in pediatric patients at 1 year. However, larger, more long-term studies are required to ascertain its effectiveness.

Systematic review and meta-analysis of the impact of depression on subsequent smoking cessation in patients with chronic respiratory conditions.

OBJECTIVE: To systematically review the impact of depression on subsequent smoking cessation in prospective studies of chronic respiratory patients. METHOD: A systematic search of electronic databases (MEDLINE, PsycINFO, CINAHL) was conducted to identify prospective studies of chronic respiratory patients that measured depression at baseline and smoking status at follow-up, dating from 1st January 1990 to 21st February 2014. The standardized mean difference (SMD) and 95% confidence interval (CI) for the association between baseline depressive symptoms and subsequent smoking cessation was estimated from available data using random effects meta-analysis. RESULTS: A total of 1314 citations were retrieved and 197 articles were further evaluated by two reviewers. Seven articles provided sufficient data to estimate the association between depressive symptoms and subsequent smoking cessation. Those with elevated depressive symptoms were significantly less likely to quit smoking at follow-up than those not reporting elevated depressive symptoms (SMD=-.31, 95% CI -.43 to -.19; I(2)=0%, P=.506). CONCLUSIONS: The association between depression and subsequent smoking was poorly reported or omitted in most studies. However, the available evidence suggests that depression decreases the likelihood that patients with chronic respiratory conditions will quit smoking. Future research is needed to determine how best to manage depression and smoking cessation in this population.

Transarterial Embolization of Angiomyolipoma: A Systematic Review.

INTRODUCTION: Transarterial embolization is increasingly used in the management of renal angiomyolipoma. The level of evidence establishing the safety and efficacy of transarterial embolization has not increased in parallel. MATERIALS AND METHODS: Using the MOOSE (Meta-analysis Of Observational Studies in Epidemiology) criteria a systematic review of transarterial embolization of angiomyolipoma was performed to establish procedural safety and efficacy. A MEDLINE® PubMed® search revealed 1,739 publications, of which 31 studies met eligibility criteria. RESULTS: A total of 524 cases of transarterial embolization of angiomyolipoma were included in analysis. Self-limiting post-embolization syndrome developed following 35.9% of embolizations and further morbidity developed in 6.9%. No procedural mortality was reported. At a mean followup of 39 months the mean size reduction was 3.4 cm (-38.3% of angiomyolipoma diameter). Unplanned repeat embolization or surgery was required in 20.9% of cases during this period. The most frequent indications for repeat procedures included angiomyolipoma revascularization in 30.0% of cases, unchanged or increasing size in 22.6%, refractory or recurring symptoms in 16.7% and representation with acute retroperitoneal hemorrhage in 14.3%. Treatment included a combination of 2 or more embolic agents in 46.8% of cases, ethanol monotherapy in 41.7%, coil monotherapy in 6.2% and foam or microparticle monotherapy in 5.2%. CONCLUSIONS: Transarterial embolization of angiomyolipoma demonstrates low rates of mortality and serious complications. Re-treatment rates and size reduction at a mean followup of 39 months are presented. Longitudinal data assessing long-term size reduction and re-treatment rates are lacking. Recommendations guiding the indications for transarterial embolization and clear followup require further longitudinal data.

Sex dependent risk factors for mortality after myocardial infarction: individual patient data meta-analysis.

BACKGROUND: Although a number of risk factors are known to predict mortality within the first years after myocardial infarction, little is known about interactions between risk factors, whereas these could contribute to accurate differentiation of patients with higher and lower risk for mortality. This study explored the effect of interactions of risk factors on all-cause mortality in patients with myocardial infarction based on individual patient data meta-analysis. METHODS: Prospective data for 10,512 patients hospitalized for myocardial infarction were derived from 16 observational studies (MINDMAPS). Baseline measures included a broad set of risk factors for mortality such as age, sex, heart failure, diabetes, depression, and smoking. All two-way and three-way interactions of these risk factors were included in Lasso regression analyses to predict time-to-event related all-cause mortality. The effect of selected interactions was investigated with multilevel Cox regression models. RESULTS: Lasso regression selected five two-way interactions, of which four included sex. The addition of these interactions to multilevel Cox models suggested differential risk patterns for males and females. Younger women (age<50) had a higher risk for all-cause mortality than men in the same age group (HR 0.7 vs. 0.4), while men had a higher risk than women if they had depression (HR 1.4 vs. 1.1) or a low left ventricular ejection fraction (HR 1.7 vs. 1.3). Predictive accuracy of the Cox model was better for men than for women (area under the curves: 0.770 vs. 0.754). CONCLUSIONS: Interactions of well-known risk factors for all-cause mortality after myocardial infarction suggested important sex differences. This study gives rise to a further exploration of prediction models to improve risk assessment for men and women after myocardial infarction.

The association between self-reported lifestyle changes and health-related quality of life in coronary patients: the EUROASPIRE III survey.

BACKGROUND: Patients with coronary heart disease often suffer from an impaired health-related quality of life (HRQoL). A healthier lifestyle not only extends individuals' lengths of life but might also improve their HRQoL. The aim of this study was to explore the relation between self-reported lifestyle changes and HRQoL in European coronary patients. METHODS: Data on 8745 coronary patients, from 22 countries, participating in the EUROASPIRE III survey (2006-2007) were used. These patients hospitalized for coronary artery bypass graft, percutaneous coronary intervention, acute myocardial infarction, or myocardial ischaemia were interviewed and examined at least 6 months and no later than 3 years after their hospital admission to gather information on their HRQoL, self-reported lifestyle changes, and risk factors. RESULTS: Significantly better HRQoL scores were found in ex-smokers compared to current smokers. Patients who made an attempt to increase their physical activity level had a better HRQoL compared to those who had not made an attempt. Furthermore dietary changes were associated with HRQoL, with better outcomes in patients who tried to reduce fat and salt intake and increase fish, fruit, and vegetable intake. The intention to change behaviour was not associated with HRQoL. CONCLUSIONS: Better HRQoL scores were found in those coronary patients who adopted a healthier lifestyle. The actual lifestyle changes - smoking cessation, increasing physical activity, and adopting a healthy diet - and not the intention to change are associated with better HRQoL outcomes.
