Background and Objectives: Neurological involvement associated with SARS-CoV-2 infection is increasingly recognized. However, the specific characteristics and prevalence in pediatric patients remain unclear. The objective of this study was to describe the neurological involvement in a multinational cohort of hospitalized pediatric patients with SARS-CoV-2. Methods: This was a multicenter observational study of children Results: One-hundred forty-seven (21%) of 697 hospitalized children with SARS-CoV-2 infection had neurological signs/symptoms. Headache (n = 103), encephalopathy (n = 28), and seizures (n = 30) were the most reported. Neurological signs/symptoms were significantly associated with ICU admission (OR: 1.71, 95% CI: 1.15–2.55; p = 0.008), satisfaction of MIS-C criteria (OR: 3.71, 95% CI: 2.46–5.59; p < 0.001), fever during hospitalization (OR: 2.15, 95% CI: 1.46–3.15; p < 0.001), and gastrointestinal involvement (OR: 2.31, 95% CI: 1.58–3.40; p < 0.001). Non-headache neurological manifestations were significantly associated with ICU admission (OR: 1.92, 95% CI: 1.08–3.42; p = 0.026), underlying neurological disorders (OR: 2.98, 95% CI: 1.49–5.97, p = 0.002), and a history of fever prior to hospital admission (OR: 2.76, 95% CI: 1.58–4.82; p < 0.001). Discussion: In this study, approximately 21% of hospitalized children with SARS-CoV-2 infection had neurological signs/symptoms. Future studies should focus on pathogenesis and long-term outcomes in these children.

SARS-CoV-2 infection can lead to multisystem inflammatory syndrome in children (MIS-C). We sought to investigate risk factors for admission to the intensive care unit (ICU) and explored changes in disease severity over time.We obtained data from chart reviews of children younger than 18 years with confirmed or probable MIS-C who were admitted to 15 hospitals in Canada, Iran and Costa Rica between Mar. 1, 2020, and Mar. 7, 2021. Using multivariable analyses, we evaluated whether admission date and other characteristics were associated with ICU admission or cardiac involvement.Of 232 children with MIS-C (median age 5.8 yr), 130 (56.0%) were male and 50 (21.6%) had comorbidities. Seventy-three (31.5%) patients were admitted to the ICU but none died. We observed an increased risk of ICU admission among children aged 13-17 years (adjusted risk difference 27.7%, 95% confidence interval [CI] 8.3% to 47.2%), those aged 6-12 years (adjusted risk difference 25.2%, 95% CI 13.6% to 36.9%) or those with initial ferritin levels greater than 500 μg/L (adjusted risk difference 18.4%, 95% CI 5.6% to 31.3%). Children admitted to hospital after Oct. 31, 2020, had numerically higher rates of ICU admission (adjusted risk difference 12.3%, 95% CI -0.3% to 25.0%) and significantly higher rates of cardiac involvement (adjusted risk difference 30.9%, 95% CI 17.3% to 44.4%). At Canadian sites, the risk of ICU admission was significantly higher for children admitted to hospital between December 2020 and March 2021 than those admitted between March and May 2020 (adjusted risk difference 25.3%, 95% CI 6.5% to 44.0%).We observed that age and higher ferritin levels were associated with more severe MIS-C. We observed greater severity of MIS-C later in the study period. Whether emerging SARS-CoV-2 variants pose different risks of severe MIS-C needs to be determined.

The objective of this study was to describe the clinical course and outcomes in children with technology dependence (TD) hospitalized with SARS-CoV-2 infection.Seventeen pediatric hospitals (15 Canadian and one each in Iran and Costa Rica) included children up to 17 years of age admitted February 1, 2020, through May 31, 2021, with detection of SARS-CoV-2. For those with TD, data were collected on demographics, clinical course and outcome.Of 691 children entered in the database, 42 (6%) had TD of which 22 had feeding tube dependence only, 9 were on supplemental oxygen only, 3 had feeding tube dependence and were on supplemental oxygen, 2 had a tracheostomy but were not ventilated, 4 were on non-invasive ventilation, and 2 were on mechanical ventilation prior to admission. Three of 42 had incidental SARS-CoV-2 infection. Two with end-stage underlying conditions were transitioned to comfort care and died. Sixteen (43%) of the remaining 37 cases required increased respiratory support from baseline due to COVID-19 while 21 (57%) did not. All survivors were discharged home.Children with TD appear to have an increased risk of COVID-19 hospitalization. However, in the absence of end-stage chronic conditions, all survived to discharge.

Coagulopathy and thrombosis associated with SARS-CoV-2 infection are well defined in hospitalized adults and leads to adverse outcomes. Pediatric studies are limited.An international multicentered (n = 15) retrospective registry collected information on the clinical manifestations of SARS-CoV-2 and multisystem inflammatory syndrome (MIS-C) in hospitalized children from February 1, 2020 through May 31, 2021. This sub-study focused on coagulopathy. Study variables included patient demographics, comorbidities, clinical presentation, hospital course, laboratory parameters, management, and outcomes.Nine hundred eighty-five children were enrolled, of which 915 (93%) had clinical information available; 385 (42%) had symptomatic SARS-CoV-2 infection, 288 had MIS-C (31.4%), and 242 (26.4%) had SARS-CoV-2 identified incidentally. Ten children (1%) experienced thrombosis, 16 (1.7%) experienced hemorrhage, and two (0.2%) experienced both thrombosis and hemorrhage. Significantly prevalent prothrombotic comorbidities included congenital heart disease (p-value .007), respiratory support (p-value .006), central venous catheter (CVC) (p = .04) in children with primary SARS-CoV-2 and in those with MIS-C included respiratory support (p-value .03), obesity (p-value .002), and cytokine storm (p = .012). Comorbidities prevalent in children with hemorrhage included age10 years (p = .04), CVC (p = .03) in children with primary SARS-CoV-2 infection and in those with MIS-C encompassed thrombocytopenia (p = .001) and cytokine storm (p = .02). Eleven patients died (1.2%), with no deaths attributed to thrombosis or hemorrhage.Thrombosis and hemorrhage are uncommon events in children with SARS-CoV-2; largely experienced by those with pre-existing comorbidities. Understanding the complete spectrum of coagulopathy in children with SARS-CoV-2 infection requires ongoing research.

Age is the most important determinant of COVID-19 severity. Infectious disease severity by age is typically J-shaped, with infants and the elderly carrying a high burden of disease. We report on the comparative disease severity between infants and older children in a multicenter retrospective cohort study of children 0 to 17 years old admitted for acute COVID-19 from February 2020 through May 2021 in 17 pediatric hospitals. We compare clinical and laboratory characteristics and estimate the association between age group and disease severity using ordinal logistic regression. We found that infants comprised one-third of cases, but were admitted for a shorter period (median 3 days IQR 2-5 versus 4 days IQR 2-7), had a lower likelihood to have an increased C-reactive protein, and had half the odds of older children of having severe or critical disease (OR 0.50 (95% confidence interval 0.32-0.78)). Conclusion: When compared to older children, there appeared to be a lower threshold to admit infants but their length of stay was shorter and they had lower odds than older children of progressing to severe or critical disease. What is Known: • A small proportion of children infected with SARS-CoV-2 require hospitalization for acute COVID-19 with a subgroup needing specialized intensive care to treat more severe disease. • For most infectious diseases including viral respiratory tract infections, disease severity by age is J-shaped, with infants having more severe disease compared to older children. What is New: • One-third of admitted children for acute COVID-19 during the first 14 months of the pandemic were infants. • Infants had half the odds of older children of having severe or critical disease.

ImportanceChildren are less likely than adults to have severe outcomes from SARS-CoV-2 infection and the corresponding risk factors are not well established.ObjectiveTo identify risk factors for severe disease in symptomatic children hospitalized for PCR-positive SARS-CoV-2 infection.DesignCohort study, enrollment from February 1, 2020 until May 31, 2021Setting15 children’s hospitals in Canada, Iran, and Costa RicaParticipantsPatients ExposuresVariables assessed for their association with disease severity included patient demographics, presence of comorbidities, clinical manifestations, laboratory parameters and chest imaging findings.Main Outcomes and MeasuresThe primary outcome was severe disease defined as a WHO COVID-19 clinical progression scale of ≥6, i.e., requirement of non-invasive ventilation, high flow nasal cannula, mechanical ventilation, vasopressors, or death. Multivariable logistic regression was used to evaluate factors associated with severe disease.ResultsWe identified 403 hospitalizations. Median age was 3.78 years (IQR 0.53-10.77). At least one comorbidity was present in 46.4% (187/403) and multiple comorbidities in 18.6% (75/403). Severe disease occurred in 33.8% (102/403). In multivariable analyses, presence of multiple comorbidities (adjusted odds ratio 2.24, 95% confidence interval 1.04-4.81), obesity (2.87, 1.19-6.93), neurological disorder (3.22, 1.37-7.56), anemia, and/or hemoglobinopathy (5.88, 1.30-26.46), shortness of breath (4.37, 2.08-9.16), bacterial and/or viral coinfections (2.26, 1.08-4.73), chest imaging compatible with COVID-19 (2.99, 1.51-5.92), neutrophilia (2.60, 1.35-5.02), and MIS-C diagnosis (3.86, 1.56-9.51) were independent risk factors for severity. Comorbidities, especially obesity (40.9% vs 3.9%, pConclusions and RelevancePediatric risk factors for severe SARS-CoV-2 infection vary according to age and can potentially guide vaccination programs and treatment approaches in children.Key pointsQuestionWhat are the risk factors for severe disease in children hospitalized for PCR-positive SARS-CoV-2 infection?FindingsIn this multinational cohort study of 403 children, multiple comorbidities, obesity, neurological disorder, anemia, and/or hemoglobinopathy, shortness of breath, bacterial and/or viral coinfections, chest imaging compatible with COVID-19, neutrophilia, and MIS-C diagnosis were independent risk factors for severity. The risk profile and presence of comorbidities differed between pediatric age groups, but age itself was not associated with severe outcomes.MeaningThese results can inform targeted treatment approaches and vaccine programs that focus on patient groups with the highest risk of severe outcomes.

ObjectiveTo identify risk factors for severe disease in children hospitalised for SARS-CoV-2 infection.DesignMulticentre retrospective cohort study.Setting18 hospitals in Canada, Iran and Costa Rica from 1 February 2020 to 31 May 2021.PatientsChildrenMain outcome measureSeverity on the WHO COVID-19 Clinical Progression Scale was used for ordinal logistic regression analyses.ResultsWe identified 403 hospitalisations. Median age was 3.78 years (IQR 0.53–10.77). At least one comorbidity was present in 46.4% (187/403) and multiple comorbidities in 18.6% (75/403). Eighty-one children (20.1%) met WHO criteria for PCR-positive MIS-C. Progression to WHO clinical scale score ≥6 occurred in 25.3% (102/403). In multivariable ordinal logistic regression analyses adjusted for age, chest imaging findings, laboratory-confirmed bacterial and/or viral coinfection, and MIS-C diagnosis, presence of a single (adjusted OR (aOR) 1.90, 95% CI 1.13 to 3.20) or multiple chronic comorbidities (aOR 2.12, 95% CI 1.19 to 3.79), obesity (aOR 3.42, 95% CI 1.76 to 6.66) and chromosomal disorders (aOR 4.47, 95% CI 1.25 to 16.01) were independent risk factors for severity. Age was not an independent risk factor, but different age-specific comorbidities were associated with more severe disease in age-stratified adjusted analyses: cardiac (aOR 2.90, 95% CI 1.11 to 7.56) and non-asthma pulmonary disorders (aOR 3.07, 95% CI 1.26 to 7.49) in childrenConclusionWe identified risk factors for disease severity among children hospitalised for PCR-positive SARS-CoV-2 infection. Comorbidities predisposing children to more severe disease may vary by age. These findings can potentially guide vaccination programmes and treatment approaches in children.

Background Understanding antibiotic profiles and their resistance patterns can improve hospital quality care and optimize clinical outcomes. This paper characterizes the use of meropenem in the National Children’s Hospital of Caja Costarricense del Seguro Social (CCSS) in Costa Rica, and its role in antibiotic stewardship. Methods This is a retrospective observational study from hospitalized patients under 13 years of age that received meropenem as part of their treatment. Patients were identified through medical and pharmacy records. Data was summarized using frequencies and percentages for categorical variables, means and standard deviations for normally distributed continuous variables, and medians with interquartile ranges (IQR) for non-normally distributed continuous variables. Results A total of 181 of the 309 selected patients met inclusion criteria. Median age was 21 months (IQR: 4.0-79.0). Mean length of stay was 31 days (16.0-58.0). The most frequent diagnosis was septic shock (29%). 87% of patients received at least one antibiotic prior to receiving meropenem; 71% of patients received a second antibiotic simultaneously with meropenem. In 113 (62%) cases, meropenem was prescribed as empirical therapy. The most frequent isolate was extended-spectrum s-lactamase Escherichia coli (24%). 74% of patients who received meropenem as targeted therapy had a favorable outcome. Conclusions Meropenem can be used as monotherapy for complicated, multi-drug resistant, gram negative, bacterial infections, due to its susceptibility profile, convenient dosing schedule, and minimum adverse effects. However, it should be restricted to cases where no other drug is available in order to safeguard its value.

BACKGROUNDSARS-CoV-2 infection can lead to multisystem inflammatory syndrome in children (MIS-C). We investigated risk factors for severe disease and explored changes in severity over time.METHODSChildren up to 17 years of age admitted March 1, 2020 through March 7th, 2021 to 15 hospitals in Canada, Iran and Costa Rica with confirmed or probable MIS-C were included. Descriptive analysis and comparison by diagnostic criteria, country, and admission date was performed. Adjusted absolute average risks (AR) and risk differences (RD) were estimated for characteristics associated with ICU admission or cardiac involvement.RESULTSOf 232 cases (106 confirmed) with median age 5.8 years, 56% were male, and 22% had comorbidities. ICU admission occurred in 73 (31%) but none died. Median length of stay was 6 days (inter-quartile range 4-9). Children 6 to 12 years old had the highest AR for ICU admission (44%; 95% confidence interval [CI] 34-53). Initial ferritin greater than 500 mcg/L was associated with ICU admission. When comparing cases admitted up to October 31, 2020 to those admitted later, the AR for ICU admission increased from 25% (CI 17-33) to 37% (CI 29-46) and for cardiac involvement from 44% (CI 35-53) to 75% (CI 66-84). Risk estimates for ICU admission in the Canadian cohort demonstrated a higher risk in December 2020-March 2021 compared to March-May 2020 (RD 25%; 95%CI 7-44).INTERPRETATIONMIS-C occurred primarily in previously well children. Illness severity appeared to increase over time. Despite a high ICU admission incidence, most children were discharged within one week.

BackgroundA cohort study was conducted to describe and compare the characteristics of SARS-CoV-2 infection in hospitalized children in three countries.MethodsThis was a retrospective cohort of consecutive children admitted to 15 hospitals (13 in Canada and one each in Iran and Costa Rica) up to November 16, 2020. Cases were included if they had SARS-CoV-2 infection or multi-system inflammatory syndrome in children (MIS-C) with molecular detection of SARS-CoV-2 or positive SARS-CoV-2 serology.ResultsOf 211 included cases (Canada N=95; Costa Rica N=84; Iran N=32), 103 (49%) had a presumptive diagnosis of COVID-19 or MIS-C at admission while 108 (51%) were admitted with other diagnoses. Twenty-one (10%) of 211 met criteria for MIS-C. Eighty-seven (41%) had comorbidities. Children admitted in Canada were older than those admitted to non-Canadian sites (median 4.1 versus 2.2 years; pConclusionsApproximately half of hospitalized children with confirmed SARS-CoV-2 infection or MIS-C were admitted with other suspected diagnoses. Disease severity was higher at non-Canadian sites. Neonates, children with comorbidities and those with chest radiographs compatible with COVID-19 were at increased risk for severe or critical COVID-19.Main pointsApproximately half of hospitalized children with laboratory confirmed MIS-C or SARS-CoV-2 infection were admitted with another primary diagnoses. The severity of disease was higher in the middle income countries (Costa Rica and Iran) than in Canada.

Background: Knowledge about neurological manifestations of SARS-CoV-2 in children is limited. We describe neurological manifestations in an international cohort of hospitalized pediatric patients. Methods: This is a multi-national observational study involving tertiary healthcare institutions in Canada, Costa Rica and Iran. We included patients 1 day-18 years admitted for any medical reason February 1, 2020-January 31, 2021 with laboratory evidence of SARS-CoV-2 infection by RT-PCR or serological testing. Descriptive analyses and logistic regression were performed where appropriate using JASP version 0⋅13. Findings: 298 hospitalized children with confirmed SARS-CoV-2 infection (median age 3⋅9 years [IQR 0⋅6-10⋅1]) from Canada (n=152), Costa Rica (n=115) and Iran (n=31) were included. Fifty-one (17%) had neurological manifestations, of which headache (73%), seizures (23%) and altered mental status (6%) were most frequently seen. Children with neurological symptoms had equivalent rates of comorbidities overall but were more likely to have underlying chronic neurological conditions. Additionally, those with neurological symptoms were more likely to be admitted to the ICU (15/51 [29%] vs. 32/247 [13%]; p =0⋅0033) and had longer length of hospital stay (6 days [IQR 3-8] vs. 4 days [IQR 2-7]; p =0⋅0060). Abnormalities were found in all children with neurological manifestations who received neuroimaging (n=6). Neurological manifestations were seen in 19% of the Iranian cohort, 23% of the Costa Rican cohort, and 12% of the Canadian cohort. Country of residence Costa Rica (adjusted OR: 2⋅520, 95% CI: 1⋅325-4⋅791, p =0⋅005), ICU admission (adjusted OR: 2⋅678, 95% CI: 1⋅307-5⋅486, p =0⋅007) and number of acute SARS-CoV-2 infection symptoms (adjusted OR: 1⋅355, 95% CI: 1⋅232-1⋅491, p

Secondary bacterial infections following Viperidae snakebite envenomation in children are common. Among 75 patients admitted because of snakebites at the only pediatric hospital in Costa Rica, 16 (21.3%) had a culture-confirmed secondary bacterial infection. Morganella morganii (37.5%), Aeromonas hydrophila (31.2%), and Providencia rettgeri (18.7%) were the most common pathogens. Empiric prophylaxis is still recommended and should be based on local etiological agents and antimicrobial susceptibilities.

Background Differences in clinical presentation and viral loads according to age in young children with RSV, and their correlation with disease severity are poorly defined. The aim of this study was to define age-dependent the differences in demographic, clinical factors and viral loads between children < 2 years of age with mild RSV infection evaluated as outpatients versus those hospitalized with severe RSV infection. Figure 1. Sign and Symptoms according to disease severity and age in infants with RSV infection. Most relevant signs and symptoms were stratified in outpatients (orange) vs inpatients (blue) by age in (A) < 3 months, (B) between 3 and 6 months, and (C) > 6 to 24 months of age. The Y axis represents the signs and symptoms in the two disease severity groups and the X axis the frequency of that specific symptom (%). Numbers next to bars represent the exact number of patients with that specific sign/symptom. Comparisons by Fisher exact test. Symbol (*) indicate significant 2-sided p values Figure 2. Viral load differences according to age in infants with RSV infection. The Y axis represents RSV loads in log10 copies/mL and the X axis differences in viral loads in outpatients (orange) and inpatients (blue) in the three age groups. Comparisons by Mann Whitney test. Methods Previously healthy children < 2 years old with mild (outpatients) and severe (inpatients) RSV infection were enrolled and nasopharyngeal swabs were obtained for RSV typing and quantitation by real-time PCR. Patients were stratified by age (0-< 3, 3-6, and >6-24 months) and multivariable analyses were performed to identify clinical and viral factors associated with severe disease. Results From 2014-2018 we enrolled 534 children with RSV infection: 130 outpatients and 404 inpatients. Median duration of illness was 4 days for both groups, yet viral loads were higher in outpatients than inpatient in the three age groups (Fig 1). Wheezing was more frequent in outpatients of older age (>3 months) than in inpatients (p< 0.01), while fever was more common in inpatients that outpatients (p< 0.01) and increased with age (Fig 2). Adjusted analyses confirmed that increased work of breathing and fever were consistently associated with hospitalization irrespective of age, while wheezing in infants >3 months, and higher RSV loads in children >6-24 months were independently associated with reduced disease severity. Conclusion Age had a significant impact defining the interactions among viral loads, specific clinical manifestations and disease severity in children with RSV infection. These observations highlight the importance of patient stratification when evaluating interventions against RSV.

ObjectivesAlthough devastating acute effects associated with snake envenoming are well described, the long-term sequelae resulting from these envenomings have not been adequately addressed, especially in the paediatric population. The aim of our study is to describe the clinical characteristics among paediatric patients in Costa Rica who developed long-term sequelae secondary to snakebite envenoming.DesignRetrospective descriptive study of paediatric patients under 13 years who were admitted with a history of a recent snakebite at the National Children’s Hospital in Costa Rica from January 2001 to December 2014.ResultsWe enrolled 74 patients admitted to our centre due to envenoming, and separated those who did not develop sequelae (50 patients) from those who did (24 patients). Of those who presented acute complications during hospitalisation, local wound infection and clinically diagnosed compartmental syndrome were significantly higher in the group that developed sequelae thereafter. Hypertrophic scars (66.7%), functional limitation of affected limb (37.5%) and the need of skin graft (37.5%) were the most common sequelae. The median follow-up of patients with long-term sequelae after discharge was 25.4 months (5.6–59.4). No deaths were reported during this time period.ConclusionsGiven the high economic, personal and healthcare burden that entails follow-up of these patients, efforts should be carried out to prevent the factors associated with sequelae among the affected population.

Background: Introduced in June 2017 by the World Health Organization (WHO) as a Neglected Tropical Diseases, snakebite envenoming is a global health problem. In Costa Rica, an incidence of 15 per 100,000 inhabitants and a mortality rate of 0·15 per 100,000 inhabitants per year were reported from 2005-2012. Children are also affected and prone to complications. Methods: Retrospective descriptive 14-year study of children with envenomings by Viperidae snakebites managed at the tertiary pediatric hospital in Costa Rica. Findings: 80 patients (pts) were included and classified as having mild (17 pts, 29·3%), moderate (58 pts, 72·5%) or severe (5 pts, 6·2%) envenoming. 52/80 (65%) patients received treatment within the first four hours, three (3·75%) between 5-8 hours, three between 9-12 hours, four (4%) between 13-16 hours, two (2·5%) between 17-20 hours, and seven (8·75%) after 20 hours. Edema was documented in 76/80 (95%), pain in 58 (72·5%), local bleeding in 23 (28·8%), emesis in 10 (12·5%), bullae formation in 8 (10%), and tissue necrosis in three (3·8%) pts. Complications presented according with degree of envenoming, being more common in severe cases: wound infection occurred in 14/58 (24·1%) with moderate envenoming and 5/5 pts with severe envenoming (p

Background Costa Rica (CR) has local transmission of Zika Virus (ZIKV) Infection since February 2016. Perinatal exposure (PE) and infection (PI) cases have been documented. Following a national protocol, reporting and follow-up of patients is mandatory. 2018 data of CR reported 272 women with confirmed ZIKV infection during pregnancy. Even though neurological sequelae are described in PI, including microcephaly, affected patients can develop symptoms within months after birth with development, language, and behavior alterations. Methods Retrospective descriptive study of patients born from August 1, 2016 until July 31, 2018, with laboratory confirmed PE. Follow-up was performed at referral hospital. Results 101 patients were enrolled (37% of all national confirmed perinatal ZIKV exposure during study period). Median age of first evaluation was 5 months (range: 0.6–21). 86/101 (86%) were classified as adequate term infants. 34/101 (33.7%) mothers got infected at first trimester, 55 (54.4%) at second, and 11 (10.8%) at third trimester. No data available in one. 8/101 (8%) patients had microcephaly at birth, with only 3/101 (3%) with persistence at follow-up, and 3/101 (3%) developed it later (after 9 months). 3/101 (3%) had confirmed congenital ZIKV syndrome (laboratory confirmation in symptomatic children), and 2 (2%) congenital ZIKV infection (laboratory confirmation in asymptomatic child). 6/101 (6%) had tone abnormalities and global development delay. 9 (9%) had central nervous system (CNS) ultrasound abnormalities, and 3 (3%) developed seizures. 2 (2%) had visual abnormalities, 1 (1%) had hearing impairment, 4 (4%) developed eating abnormalities, 6 (6%) developed language delay, and 4 (4%) had hyperactive behavior. All findings were divided according to maternal trimester of infection. Conclusion PI is a health problem in CR. Microcephaly at is infrequent, with international data showing it affects less than 1% of newborns. Most motor and development delay were documented in patients infected early during pregnancy, but specific language and behavior abnormalities also affected patients with later PE. Mortality was not documented, but significant CNS abnormalities were evident in congenital ZIKV syndrome patients. Disclosures All authors: No reported disclosures.
