RESUMEN
OBJECTIVES: Most children with uncomplicated urinary tract infections (UTI) can be managed with oral antibiotics. However, identifying those likely to fail oral and need intravenous antibiotics due to complicating features at presentation is challenging. We aimed to derive, validate and test a score to guide initial antibiotic route. DESIGN: This cohort study enrolled children both prospectively and retrospectively. Patients were divided into two groups based on whether they received intravenous or oral antibiotics after 24 hours, including those who switched between routes. Children diagnosed with confirmed UTI were used to derive then validate the score, comparing complicating clinical features between the two groups. Combinations of significantly differentiating features generated receiver operating characteristic curves and the optimal cut-off for intravenous antibiotic use was selected. SETTING: The emergency department of a tertiary paediatric hospital. PARTICIPANTS: All children aged 3 months-17 years with suspected UTI were eligible, and were included if they fulfilled the diagnostic criteria for UTI. OUTCOME MEASURES: The effectiveness of the derived clinical score to differentiate patients at presentation who had complicated UTI requiring ongoing intravenous antibiotics. RESULTS: There were 1240 patients, of whom 167 children aged 12 months-11 years with confirmed UTI comprised the derivation cohort. The combination of features that performed optimally (area under curve 0.85, 95% CI 0.79 to 0.91) were: rigors, urological abnormality, fever (≥38°C), emesis, recurrent (≥3) UTI, tachycardia: the RUPERT score (1 point each, maximum 6). A score ≥3 accurately classified route of antibiotics after 24 hours for 80% patients (sensitivity 77%, specificity 81%). For the 168 patients in the validation cohort, the score accurately classified 76% (sensitivity 67%, specificity 78%). The score tested well in 'probable' UTI and adolescents, and less well in infants. CONCLUSION: The Melbourne RUPERT score provides the first standardised, easy-to-use score to aid clinicians in deciding route of antibiotics for more complicated UTI in children. It now needs prospective validation.

OBJECTIVE: Home management of infants admitted to hospital with bronchiolitis would alleviate pressure on hospital beds. We aim to understand the proportion of children requiring active care interventions (ie, oxygen, fluids), caregiver perspectives and potential impact of transitioning hospital-level care of infants with bronchiolitis to home. METHODS: This is a mixed-methods study in an Australian tertiary paediatric hospital. Semistructured interviews with caregivers of infants with bronchiolitis focused on attitudes towards managing bronchiolitis at home. Interviews were analysed using inductive thematic analysis. Data on bronchiolitis admissions among infants aged 1-12 months were extracted from the electronic medical record from April 2016 to October 2020. Potential bed-days saved were calculated. RESULTS: 18 parents were interviewed, with themes emerging of 'hospital is safe', 'hospital incurs costs' and 'knowledge is power'. During 4.5 years, 2367 infants were admitted to hospital with bronchiolitis: a total of 4557 bed-days. Of these, 40% of infants were admitted for monitoring alone, 25% for nasogastric fluid support, 17% for oxygen therapy and 7.5% for both fluids and oxygen. 11% received treatments not currently feasible at home (high-flow oxygen, intravenous fluids). Oxygen therapy accounted for the largest number of bed-days (242 bed-days/year). CONCLUSION: Managing bronchiolitis at home could have a substantial impact on hospital bed demand, with an estimated 344 bed-days saved per year if all interventions were offered. Parent willingness to transfer to home balances the perceived safety of the hospital versus the financial, logistic and emotional costs. Empowering parents with knowledge was seen as a substantial facilitator of supporting transition to the home.
RESUMEN
Community Pharmacists (CPs) are easily accessible and can advocate for the appropriate use of antibiotics in children. Semi-structured interviews were conducted with 47 CPs and 46 parents/caregivers. Both groups expressed challenges to intervening when antibiotics have already been prescribed and highlighted the need for more support for CPs to make informed decisions.

OBJECTIVES: During the COVID-19 pandemic, we expanded our Hospital-in-the-Home (HITH) programme to increase capacity and manage COVID-19-positive children. We aimed to assess impact on overall HITH activity and COVID-19-positive outcomes. DESIGN: Prospective comparative cohort study. SETTING: The largest paediatric HITH in Australasia, at The Royal Children's Hospital Melbourne. PATIENTS: Children 0-18 years admitted to HITH during the pandemic. INTERVENTION: We developed a COVID-19 responsive service, and a guideline for COVID-19-positive patients. We compared overall activity prior to and during the pandemic, and COVID-19-positive admissions with different variants. MAIN OUTCOMES: We compared outcomes for all HITH patients before and during the pandemic, and for COVID-19-positive patients admitted first to hospital versus directly to HITH. RESULTS: HITH managed 7319 patients from March 2020 to March 2022, a 21% increase to previously, with a 132% telehealth increase. 421 COVID-19-positive patients (3 days-18.9 years) were admitted to HITH, predominantly high risk (63%) or moderately unwell (33%). Rates of childhood infection in Victoria, with proportion admitted to HITH were: original/alpha variant-3/100 000/month, 0.7%; delta-92/100 000/month, 0.8%; omicron-593/100 000/month, 0.3%. Eligible parents of only 29 of 71 (41%) high-risk children were vaccinated. COVID-19-positive children admitted directly to HITH were less likely to receive COVID-19-specific treatment than those admitted to hospital first (14 of 113 (12%) vs 33 of 46 (72%), p<0.001), reflecting more severe respiratory, but not other features in inpatients. 15 of 159 (10%) were readmitted to hospital, but none deteriorated rapidly. CONCLUSIONS: COVID-19-positive children at high risk or with moderate symptoms can be managed safely via HITH at home, the ideal place for children during the pandemic.

Children are entitled to receive antibiotic therapy that is based on evidence and best practice, but might be overlooked in hospital programmes designed to achieve antimicrobial stewardship [AMS]. This failure to include children could be because children make up small proportion of patients in most hospitals, and are cared for by specialised paediatric staff. We reviewed the evidence and consulted experts in three global regions to develop ten recommendations for good-practice in hospital AMS programmes for children. We performed a review of scientific research, published between Jan 1, 2007, and Oct 17, 2019, concerning AMS, and formed a multinational expert group comprising members from the USA, Canada, the UK, Belgium, Switzerland, Australia, and Aotearoa New Zealand to develop the recommendations. These recommendations aim to help health-care workers who care for children in these regions to deliver best-practice care. We surveyed health-care workers with expertise in antibiotic therapy for children across these regions, and found that the recommendations were considered both very important and generally feasible. These recommendations should be implemented in hospitals to improve antibiotic therapy for children and to stimulate research into future improvements in care.

CONTEXT: Bronchiolitis is the leading cause of pediatric hospital admissions. Hospital-at-Home (HAH) delivers hospital-level care at home, relieving pressure on the hospital system. OBJECTIVES: We aimed to review the feasibility, acceptability, and safety of HAH for bronchiolitis, and assess the cost-impact to hospitals and society. DATA SOURCES: Ovid Medline, Embase, Pubmed, Cochrane Library, CINAHL, and Web of Science. STUDY SELECTION: Studies (randomized control trials, retrospective audits, prospective observational trials) of infants with bronchiolitis receiving HAH (oxygen, nasogastric feeding, remote monitoring). Studies were limited to English language since 2000. DATA EXTRACTION: We reviewed all studies in duplicate for inclusion, data extraction, and risk of bias. RESULTS: Ten studies met inclusion criteria, all for home oxygen therapy (HOT). One abstract on nasogastric feeding did not meet full inclusion criteria. No studies on remote monitoring were found. HOT appears feasible in terms of uptake (70%-82%) and successful completion, both at altitude and sea-level. Caregiver acceptability was reported in 2 qualitative studies. There were 7 reported adverse events (0.6%) with 0 mortality in 1257 patients. Cost studies showed evidence of savings, although included costs to hospitals only. LIMITATIONS: Small number of studies with heterogenous study design and quality. No adequately powered randomized control studies. CONCLUSIONS: Evidence exists to support HOT as feasible, acceptable, and safe. Evidence of cost-effectiveness remains limited. Further research is needed to understand the relevant impact of HAH versus alternative interventions to reduce oxygen prescribing. Other models of care looking at nasogastric feeding support and remote monitoring should be explored.

OBJECTIVE: To report the use, and assess the efficacy and outcomes of outpatient parenteral antimicrobial therapy (OPAT) in neonates (≤28 days of age), compared with older infants (1-12 months of age). DESIGN: A prospective 8-year observational study from September 2012 to September 2020. SETTING: The Hospital-in-the-Home (HITH) programme of the Royal Children's Hospital Melbourne. PATIENTS: Neonatal patients (≤28 days of age) were compared with older infants (1-12 months of age) receiving OPAT. INTERVENTIONS: Data were collected including demographics, diagnosis, type of venous access and antibiotic choice. MAIN OUTCOME MEASURES: Success of OPAT, antibiotic appropriateness, complications and readmission rate. RESULTS: There were 76 episodes for which neonates were admitted to HITH for OPAT, and 405 episodes for older infants. Meningitis was the most common diagnosis in both groups (59% and 35%, respectively); the most frequently prescribed antibiotic was ceftriaxone for both groups (61% and 49%). A positive bacterial culture was less frequent in neonates (38% vs 53%, p=0.02). Vascular access complication rate was 19% in neonates compared with 13% in older infants (p=0.2) with no central line-associated bloodstream infection in either group. Rates of appropriate antibiotic prescribing were similarly high between groups (93% vs 90%, p=0.3). The OPAT course was successfully completed in 74 of 74 (100%) neonates and 380 of 396 (96%) older infants (p=0.09). The unplanned readmission rate was low: 4 of 76 (5%) neonates and 27 of 405 (7%) older infants. CONCLUSIONS: OPAT is a safe and effective way of providing antibiotics to selected clinically stable neonatal patients. While appropriate antibiotic use was common, improvements can still be made.
RESUMEN
Invasive fungal disease (IFD) remains a common and serious complication in children treated for leukaemia. Antifungal prescription in children with leukaemia presents unique challenges, particularly due to variation in IFD risk between and within leukaemia treatment protocols, drug toxicities and interactions between antifungals and chemotherapeutic agents. With recent advances in the understanding of IFD epidemiology and large clinical trials in adults assessing antifungals for IFD treatment and prophylaxis, together with paediatric clinical and pharmacokinetic studies, there is a growing body of data to inform optimal antifungal use in children. A panel of infectious diseases and haematology-oncology clinicians with expertise in IFD management compiled a list of 10 key clinical questions following development of the 2021 Australia and New Zealand Mycology Antifungal Consensus Guidelines. A focused literature review was conducted to explore available evidence and identify gaps in knowledge to direct future research. With the changing epidemiology of IFD globally, the ongoing evolution of paediatric leukaemia treatment and the increasing availability of novel antifungal agents, advocacy for paediatric clinical studies will remain vital to optimize IFD prevention and treatment in children with leukaemia.

OBJECTIVES: The role Staphylococcus aureus antimicrobial resistance genes and toxins play in disease severity, management and outcome in childhood is an emerging field requiring further exploration. METHODS: A prospective multisite study of Australian and New Zealand children hospitalised with S. aureus bacteraemia (SAB) occurred over 24 months (2017-2018). Whole genome sequencing (WGS) data were paired with clinical information from the ISAIAH cohort. RESULTS: 353 SAB isolates were sequenced; 85% methicillin-susceptible S. aureus ([MSSA], 301/353) and 15% methicillin-resistant S. aureus ([MRSA], 52/353). There were 92 sequence types (STs), most commonly ST5 (18%) and ST30 (8%), grouped into 23 clonal complexes (CCs), most frequently CC5 (21%) and CC30 (12%). MSSA comprised the majority of healthcare-associated SAB (87%, 109/125), with principal clones CC15 (48%, 11/21) and CC8 (33%, 7/21). Panton-Valentine leukocidin (PVL)-positive SAB occurred in 22% (76/353); predominantly MSSA (59%, 45/76), community-onset (92%, 70/76) infections. For community-onset SAB, the only microbiological independent predictor of poor outcomes was PVL positivity (aOR 2.6 [CI 1.0-6.2]). CONCLUSION: From this WGS paediatric SAB data, we demonstrate the previously under-recognized role MSSA has in harbouring genetic virulence and causing healthcare-associated infections. PVL positivity was the only molecular independent predictor of poor outcomes in children. These findings underscore the need for further research to define the potential implications PVL-producing strains may have on approaches to S. aureus clinical management.

BACKGROUND: The growth of antimicrobial resistance worldwide has led to increased focus on antimicrobial stewardship (AMS) and infection prevention and control (IPC) measures, although primarily in high-income countries (HIC). We aimed to compare pediatric AMS and IPC resources/activities between low- and middle-income countries (LMIC) and HIC and to determine the barriers and priorities for AMS and IPC in LMIC as assessed by clinicians in those settings. METHODS: An online questionnaire was distributed to clinicians working in HIC and LMIC healthcare facilities in 2020. RESULTS: Participants were from 135 healthcare settings in 39 LMIC and 27 HIC. Formal AMS and IPC programs were less frequent in LMIC than HIC settings (AMS 42% versus 76% and IPC 58% versus 89%). Only 47% of LMIC facilities conducted audits of antibiotic use for pediatric patients, with less reliable availability of World Health Organization Access list antibiotics (29% of LMIC facilities). Hand hygiene promotion was the most common IPC intervention in both LMIC and HIC settings (82% versus 91%), although LMIC hospitals had more limited access to reliable water supply for handwashing and antiseptic hand rub. The greatest perceived barrier to pediatric AMS and IPC in both LMIC and HIC was lack of education: only 17% of LMIC settings had regular/required education on antimicrobial prescribing and only 25% on IPC. CONCLUSIONS: Marked differences exist in availability of AMS and IPC resources in LMIC as compared with HIC. A collaborative international approach is urgently needed to combat antimicrobial resistance, using targeted strategies that address the imbalance in global AMS and IPC resource availability and activities.

BACKGROUND: Antimicrobial stewardship (AMS) is central to the World Health Organisation Global Action Plan against antimicrobial resistance (AMR). If antibiotics are used without restraint, morbidity and mortality from AMR will continue to increase. In resource-rich settings, AMS can safely reduce antibiotic consumption. However, for children in low- and middle-income countries (LMIC), the impact of different AMS interventions is unknown. AIM: To determine the impact of different AMS interventions on antibiotic use and clinical and microbiologic outcomes in children in LMIC. METHODS: MEDLINE, Embase and PubMed were searched for studies of AMS interventions in pediatric population in LMIC settings. Controlled trials, controlled before-and-after studies and interrupted time series studies were included. Outcomes assessed were antibiotic use, multidrug-resistant organism (MDRO) rates, clinical outcomes and cost. RESULTS: Of 1462 studies, 34 met inclusion criteria including a total population of >5,000,000 in 17 countries. Twenty were in inpatients, 2 in ED, 10 in OPD and 2 in both. Seven studies were randomized controlled trials. All types of interventions reported a positive impact on antibiotic prescribing. AMS bundles with education, and clinical decision tools appeared more effective than guidelines alone. AMS interventions resulted in significantly decreased clinical infections (4/4 studies) and clinical failure (2/2) and reduced MDRO colonization rate (4/4). There was no concomitant increase in mortality (4/4 studies) or length of stay (2/2). CONCLUSION: Multiple effective strategies exist to reduce antibiotic consumption in LMIC. However, marked heterogeneity limit conclusions regarding the most effective approach, particularly regarding clinical outcomes. Overall, AMS strategies are important tools in the reduction of MDRO-related morbidity in children in LMIC.

Antimicrobial resistance is a global health threat and there is an urgent need to manage antibiotic use to slow its development. However, antimicrobial stewardship interventions in low- and middle-income countries (LMIC) have been limited in terms of their resourcing, feasibility and effectiveness in the face of greater challenges in child mortality. We sought to gather together examples of antibiotic use problems faced by clinicians in LMIC, many of which are unique to these settings, and real-world antimicrobial stewardship solutions identified, with the goal of learning broader lessons that might be applicable across LMIC.

INTRODUCTION: Home-based treatment of febrile neutropenia (FN) in children with cancer with oral or intravenous antibiotics is safe and effective. There are limited data on the economic impact of this model of care. We evaluated the cost-effectiveness of implementing an FN programme, incorporating home-based intravenous antibiotics for carefully selected patients, in a tertiary paediatric hospital. METHODS: A decision analytic model was constructed to compare costs and outcomes of the home-based FN programme, with usual in-hospital treatment with intravenous antibiotics. The programme included a clinical decision rule to stratify patients by risk for severe infection and home-based eligibility criteria using disease, chemotherapy and patient-level factors. Health outcomes (quality of life) and probabilities of FN risk classification and home-based eligibility were based on prospectively collected data between 2017 and 2019. Patient-level costs were extracted from hospital administrative records. Cost-effectiveness was expressed as the incremental cost per quality-adjusted life year (QALY). FINDINGS: The mean health care cost of home-based FN treatment in low-risk patients was Australian dollars (A$) 7765 per patient compared to A$20,396 for in-hospital treatment (mean difference A$12,632 [95% CI: 12,496-12,767]). Overall, the home-based FN programme was the dominant strategy, being more effective (0.0011 QALY [95% CI: 0.0011-0.0012]) and less costly. Results of the model were most sensitive to proportion of children eligible for home-based care programme. CONCLUSION: Compared to in-hospital FN care, the home-based FN programme is cost-effective, with savings arising from cheaper cost of caring for children at home. These savings could increase as more patients eligible for home-based care are included in the programme.

AIM: Victoria experienced two 'waves' of COVID-19 between March and September 2020 and more cases than any other jurisdiction in Australia. Although world-wide reports of COVID-19 reflect that children are less likely to experience severe disease compared with adults, hospitalisations and deaths have been reported. We report testing and outcomes of children with SARS-CoV-2 infection presenting to a tertiary paediatric hospital in Melbourne. METHODS: We conducted a prospective cohort study at The Royal Children's Hospital (RCH), including all children and adolescents (aged 0-18 years) who presented and were tested for SARS-CoV-2 over a 6-month period, between 21 March 2020, up to the 21 September 2020. Detailed epidemiological and clinical data were recorded. RESULTS: A total of 19 708 tests for SARS-CoV-2 were performed in 14 419 patients. One hundred and eighty patients tested positive for SARS-CoV-2 (1.2%). 110 (61%) were symptomatic, 60 (33%) were asymptomatic and 10 (6%) were pre-symptomatic. Close contacts of a positive case were associated with a higher risk of a testing positive for SARS-CoV-2 (120/2027 (6%) vs. 60/14589 (0.4%), RD 5.5 (95% CI 4.5 to 6.5), P < 0.001). Eighteen (10%) SARS-CoV-2-positive patients were admitted to hospital with one patient requiring intensive care. All patients recovered fully with no deaths. CONCLUSION: In Victorian children presenting to a tertiary hospital, SARS-CoV-2 infection caused predominantly mild or asymptomatic infection, with most children not requiring hospitalisation.

BACKGROUND: Staphylococcus aureus is a common cause of bacteremia, yet the epidemiology and predictors of poor outcome remain inadequately defined in childhood. METHODS: ISAIAH (Invasive Staphylococcus aureus Infections and Hospitalizations in children) is a prospective, cross-sectional study of S. aureus bacteremia (SAB) in children hospitalized in Australia and New Zealand over 24 months (2017-2018). RESULTS: Overall, 552 SABs were identified (incidence 4.4/100 000/year). Indigenous children, those from lower socioeconomic areas and neonates were overrepresented. Although 90-day mortality was infrequent, one-third experienced the composite of: length of stay >30 days (26%), intensive care unit admission (20%), relapse (4%), or death (3%). Predictors of mortality included prematurity (adjusted odds ratio [aOR],16.8; 95% confidence interval [CI], 1.6-296.9), multifocal infection (aOR, 22.6; CI, 1.4-498.5), necrotizing pneumonia (aOR, 38.9; CI, 1.7-1754.6), multiorgan dysfunction (aOR, 26.5; CI, 4.1-268.8), and empiric vancomycin (aOR, 15.7; CI, 1.6-434.4); while infectious diseases (ID) consultation (aOR, 0.07; CI .004-.9) was protective. Neither MRSA nor vancomycin trough targets impacted survival; however, empiric vancomycin was associated with nephrotoxicity (OR, 3.1; 95% CI 1.3-8.1). CONCLUSIONS: High SAB incidence was demonstrated and for the first time in a pediatric setting, necrotizing pneumonia and multifocal infection were predictors of mortality, while ID consultation was protective. The need to reevaluate pediatric vancomycin trough targets and limit unnecessary empiric vancomycin exposure to reduce poor outcomes and nephrotoxicity is highlighted. One in 3 children experienced considerable SAB morbidity; therefore, pediatric inclusion in future SAB comparator trials is paramount to improve outcomes.

OBJECTIVES: The Pre-school Osteoarticular Infection (POI) study aimed to describe the burden of disease, epidemiology, microbiology and treatment of acute osteoarticular infections (OAI) and the role of Kingella kingae in these infections. METHODS: Information about children 3-60 months of age who were hospitalized with an OAI to 11 different hospitals across Australia and New Zealand between January 2012 and December 2016 was collected retrospectively. RESULTS: A total of 907 cases (73%) were included. Blood cultures grew a likely pathogen in only 18% (140/781). The peak age of presentation was 12 to 24 months (466/907, 51%) and Kingella kingae was the most frequently detected microorganism in this age group (60/466, 13%). In the majority of cases, no microorganism was detected (517/907, 57%). Addition of PCR to culture increased detection rates of K. kingae. However, PCR was performed infrequently (63/907, 7%). CONCLUSIONS: This large multi-national study highlights the need for more widespread use of molecular diagnostic techniques for accurate microbiological diagnosis of OAI in pre-school aged children. The data from this study supports the hypothesis that a substantial proportion of pre-school aged children with OAI and no organism identified may in fact have undiagnosed K. kingae infection. Improved detection of Kingella cases is likely to reduce the average length of antimicrobial treatment.

AIM: To (i) determine the appropriateness of antimicrobial prescribing in the neonatal intensive care unit (NICU) and (ii) assess the impact of a collaborative antimicrobial stewardship (AMS) intervention on prescribing practices. METHODS: The intervention was a weekly AMS audit-feedback joint ward round (6-month period) of Neonatology and Infectious Diseases clinicians in a tertiary neonatal intensive care unit in Melbourne, Australia. Antibiotic prescriptions were audited and recommendations delivered in real time. The proportion of recommendations implemented was used to assess acceptability of the intervention. RESULTS: During the study period, there were 23 AMS rounds, during which 249 patients were reviewed at 627 separate episodes. Of these, 233 (37%) episodes were for patients receiving antimicrobials. Of these, 147 (63%) received empirical antimicrobial treatment, 43 (18%) targeted antimicrobial treatment and 43 (18%) antimicrobial prophylaxis. There were 58 (25%) of 233 episodes of inappropriate antibiotic use, and 62 recommendations for improvement. Most common recommendations were to narrow (33/62, 53%) or stop (12/62, 19%) antimicrobials. The majority (45, 73%) of recommendations were accepted, resulting in significant improvement in the proportion of the 233 episodes that had completely appropriate antibiotic prescribing: 175 (75%) to 217 (93%) (relative risk 1.2, 95% confidence intervals 1.1-1.3, P < 0.001). CONCLUSIONS: A collaborative audit-feedback AMS intervention was effective in identifying inappropriate antimicrobial prescriptions and impacted positively on treatment plans. Ancillary benefits were improved communication between departments and the revision of antimicrobial prescribing guidelines.

BACKGROUND: Candida species are the most common cause of systemic fungal infections in children. Risk factors for candidemia vary in different patient populations, posing challenges for clinical prediction of infection. We describe the epidemiology and clinical disease of candidemia in children admitted to a tertiary pediatric hospital. METHODS: Retrospective audit of children ≤18 years of age with candidemia at a tertiary pediatric hospital over a 16-year period. RESULTS: There were 139 episodes of candidemia in 124 children. A central venous catheter was present in 94% of episodes, prior antibiotic exposure in 86% and parenteral nutrition in 43%. During the study period, the proportion of candidemia due to non-albicans Candida spp. increased primarily due to a rise in C. krusei. Colonization with Candida spp. in the 30 days before developing candidemia was identified in 40% of episodes and the species was concordant in 60%. Infection at other sites was rare, including pulmonary dissemination (9/38, 24%), renal fungal disease (9/114, 8%), fungal endophthalmitis (8/102, 8%) and hepatosplenic nodules (5/92, 5%). Overall, 8/127 (6%) isolates were fluconazole-resistant (7 C. krusei and 1 C. glabrata) and 7/127 (6%) had intermediate susceptibility to fluconazole. The overall 30-day mortality was 12% and significant risk factors for mortality on multivariate analysis were male sex, liver disease and mucositis. CONCLUSIONS: Our study outlines low rates of disseminated candidiasis and low mortality associated with candidemia at our institution. Additionally, it suggests that prior colonization may be an important risk factor, however, this should be validated in large prospective controlled studies.
