RESUMO
BACKGROUND: Travellers' perception of their risk for acquiring travel-related conditions is an important contributor to decisions and behaviors during travel. In this study, we aimed to assess the differences between traveller-perceived and expert-assessed risk of travel-related conditions in children and adults travelling internationally and describe factors that influence travellers' perception of risk. METHODS: Children and adults were recruited at the Hospital for Sick Children's Family Travel Clinic between October 2014 and July 2015. A questionnaire was administered to participants to assess their perceived risk of acquiring 32 travel-related conditions using a 7-point Likert scale. Conditions were categorized as vector-borne diseases, vaccine-preventable diseases, food and water borne diseases, sexually transmitted infections and other conditions. Two certified travel medicine experts reviewed each patient's chart and assigned a risk score based on the same 7-point Likert scale. Traveller and expert risk scores were compared using paired t-tests. RESULTS: In total, 207 participants were enrolled to participate in this study, 97 children (self-reported, n = 8; parent-reported, n = 89), and 110 adults. Travel-related risk for adults and parents answering for their children were significantly underestimated when compared to expert-assessed risk for 26 of the 32 assessed conditions. The underestimated conditions were the same for both adults and parents answering for children. Travel-related risk was not over-estimated for any condition. CONCLUSIONS: Adults underestimated their children's and their own risk for most travel-related conditions. Strategies to improve the accuracy of risk perception of travel-related conditions by travellers are needed to optimize healthy travel for children and their families.

OBJECTIVE: To evaluate the cost-effectiveness of distribution of the integrated neonatal care kit (iNCK) by community health workers from the healthcare payer perspective in Rahimyar Khan, Pakistan. SETTING: Rahimyar Khan, Pakistan. PARTICIPANTS: N/A. INTERVENTION: Cost-utility analysis using a Markov model based on cluster randomised controlled trial (cRCT: NCT02130856) data and a literature review. We compared distribution of the iNCK to pregnant mothers to local standard of care and followed infants over a lifetime horizon. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was incremental net monetary benefit (INMB, at a cost-effectiveness threshold of US$15.50), discounted at 3%. Secondary outcomes were life years, disability-adjusted life years (DALYs) and costs. RESULTS: At a cost-effectiveness threshold of US$15.50, distribution of the iNCK resulted in lower expected DALYs (28.7 vs 29.6 years) at lower expected cost (US$52.50 vs 55.20), translating to an INMB of US$10.22 per iNCK distributed. These results were sensitive to the baseline risk of infection, cost of the iNCK and the estimated effect of the iNCK on the relative risk of infection. At relative risks of infection below 0.79 and iNCK costs below US$25.90, the iNCK remained cost-effective compared with current local standard of care. CONCLUSION: The distribution of the iNCK dominated the current local standard of care (ie, the iNCK is less costly and more effective than current care standards). Most of the cost-effectiveness of the iNCK was attributable to a reduction in neonatal infection.

INTRODUCTION: Ethiopia has made remarkable progress in reducing childhood and neonatal mortality in the last two decades. However, with the spread of the COVID-19 pandemic in Ethiopia, disruptions in routine health care pose a significant risk in reversing the gains made in neonatal mortality reduction. METHODS: Using the World Health Organization's health systems building blocks framework we examined the mechanisms by which the pandemic may impact neonatal health. RESULTS: Our analysis suggests that the COVID-19 pandemic and measures taken by the government to control its spread could indirectly set back the gains made in neonatal mortality reduction in Ethiopia by weakening the health system building blocks. On the other hand, by exposing longstanding issues in the health system, the pandemic has pressed health sector stakeholders to urgently test innovative approaches to maintain delivery of essential health care. CONCLUSIONS: We recommend that the Ministry of Health of Ethiopia strike a right balance between the control of the pandemic and ensuring provision of essential neonatal health services. As the pandemic continues to spread in the country, the government should avoid verticalization of pandemic response efforts and adopt a diagonal investment approach to effectively respond to the pandemic as well as build health system resilience to maintain the gains made in the neonatal health.

BACKGROUND: The overall global impact of COVID-19 in children and regional variability in pediatric outcomes are presently unknown. METHODS: To evaluate the magnitude of global COVID-19 death and intensive care unit (ICU) admission in children aged 0-19 years, a systematic review was conducted for articles and national reports as of December 7, 2020. This systematic review is registered with PROSPERO (registration number: CRD42020179696). RESULTS: We reviewed 16,027 articles as well as 225 national reports from 216 countries. Among the 3,788 global pediatric COVID-19 deaths, 3,394 (91.5%) deaths were reported from low- and middle-income countries (LMIC), while 83.5% of pediatric population from all included countries were from LMIC. The pediatric deaths/1,000,000 children and case fatality rate (CFR) were significantly higher in LMIC than in high-income countries (HIC) (2.77 in LMIC vs 1.32 in HIC; p < 0.001 and 0.24% in LMIC vs 0.01% in HIC; p < 0.001, respectively). The ICU admission/1,000,000 children was 18.80 and 1.48 in HIC and LMIC, respectively (p < 0.001). The highest deaths/1,000,000 children and CFR were in infants < 1 year old (10.03 and 0.58% in the world, 5.39 and 0.07% in HIC and 10.98 and 1.30% in LMIC, respectively). CONCLUSIONS: The study highlights that there may be a larger impact of pediatric COVID-19 fatality in LMICs compared to HICs.

Although often regarded as a foreign disease, latent tuberculosis or tuberculosis disease will be encountered in many clinical situations by the Canadian child health practitioner. There are key differences between tuberculosis in children and adults. In the present article, the changing epidemiology of tuberculosis in children in Canada and around the world, the pathogenesis of infection, diagnostic tests, and clinical management of childhood latent tuberculosis and tuberculosis disease are reviewed.
Même si la tuberculose latente et la tuberculose sont souvent considérées comme des maladies étrangères, le dispensateur canadien de soins des enfants les observera souvent dans bien des situations cliniques. Il y a des différences clés entre la tuberculose chez l'enfant et chez l'adulte. Dans le présent article, les auteurs analysent l'évolution de l'épidémiologie de la tuberculose chez les enfants du Canada et de l'étranger, la pathogenèse de l'infection, les tests diagnostiques et la prise en charge de la tuberculose latente et de la tuberculose pendant l'enfance.
RESUMO
OBJECTIVE: Invasive Neisseria meningitidis serogroup B (MenB) disease is a low incidence but severe infection (mean annual incidence 0.19/100,000/year, case fatality 11%, major long-term sequelae 10%) in Ontario, Canada. This study assesses the cost-effectiveness of a novel MenB vaccine from the Ontario healthcare payer perspective. METHODS: A Markov cohort model of invasive MenB disease based on high quality local data and data from the literature was developed. A 4-dose vaccination schedule, 97% coverage, 90% effectiveness, 66% strain coverage, 10-year duration of protection, and vaccine cost of C$75/dose were assumed. A hypothetical Ontario birth cohort (n=150,000) was simulated to estimate expected lifetime health outcomes, quality-adjusted life years (QALYs), and costs, discounted at 5%. RESULTS: A MenB infant vaccination program is expected to prevent 4.6 invasive MenB disease cases over the lifetime of an Ontario birth cohort, equivalent to 10 QALYs gained. The estimated program cost of C$46.6 million per cohort (including C$318,383 for treatment of vaccine-associated adverse events) were not offset by healthcare cost savings of C$150,522 from preventing MenB cases, resulting in an incremental cost of C$4.76 million per QALY gained. Sensitivity analyses showed the findings to be robust. CONCLUSIONS: An infant MenB vaccination program significantly exceeds commonly used cost-effectiveness thresholds and thus is unlikely to be considered economically attractive in Ontario and comparable jurisdictions.

BACKGROUND: The availability of quality data to inform policy is essential to reduce maternal deaths. To characterize maternal deaths in settings without complete vital registration systems, we designed and assessed the inter-rater reliability of a tool to systematically extract data and characterize the events that precede a nationally representative sample of maternal deaths in India. METHOD/PRINCIPAL FINDINGS: Of 1017 nationally representative pregnancy-related deaths, which occurred between 2001 and 2003, we randomly selected 105 reports. Two independent coders used the maternal data extraction tool (questions with coding guidelines) to collect information on antenatal care access, final pregnancy outcome; planned place of birth and care provider; community consultation, transport, admission, hospital referral; and verification of cause of death assignment. Kappa estimated inter-rater agreement was calculated and classified as poor (K≤0.4), moderate (Kâ=â0.4≤0.6), substantial (Kâ=â0.6≤ 0.8) and high (K>0.8) using the criteria from Landis & Koch. The data extraction tool had high agreement for gestational age, pregnancy outcome, transport, death en route and admission to hospital; substantial agreement for receipt of antenatal care, planned place of birth, readmission and referral to higher level hospital, and whether or not death occurred in the intrapartum period; moderate to substantial agreement for classification of deaths as direct or indirect obstetric deaths or incidental deaths; moderate agreement for classification of community healthcare consultation and total number of healthcare contacts; and poor agreement for the classification of deaths as sudden deaths and other/unknown cause of death. The ability of the tool to identify the most-responsible-person in labour varied from moderate agreement to high agreement. CONCLUSIONS: This data extraction tool achieved good inter-rater reliability and can be used to collect data on events surrounding maternal deaths and for verification/improvement of underlying cause of death.

Haemophilus influenzae type b (Hib) is an important cause of invasive bacterial disease in children, including meningitis and pneumonia. The introduction of Hib conjugate vaccines into routine vaccination schedules has contributed to a substantial reduction in the burden of Hib-related disease in many developed countries. However, introduction of Hib conjugate vaccines in developing countries has progressed more slowly. We review the worldwide use and effectiveness of Hib conjugate vaccines. At present, 119 countries have programmes for routine Hib immunisation. WHO estimates that in the developed world 92% of the eligible population is vaccinated against Hib; however, average coverage is 42% in developing countries and only 8% in the poorest countries. Africa and southeast Asia have the lowest rates of Hib vaccine introduction. Vaccine costs and debate about the burden of disease are obstacles to the global use of Hib conjugate vaccine. Even with new funding support, there are many ongoing challenges and vaccine use remains suboptimal, particularly in developing countries.

Clinical studies have shown the human papillomavirus (HPV) vaccines to be very effective at preventing persistent infection by vaccine serotypes. The development of these new vaccines heralds a new era in cancer prevention. Gardasil, Merck's quadravalent HPV vaccine, has recently been licensed in Canada for women aged 9 to 26 years of age. It necessitates that health professionals become familiar with the vaccine, the evidence supporting its effectiveness and issues related to vaccine strategy, cost effectiveness, and remaining research questions. The vaccine is recommended in Canada for females aged 9 to 13 years and should also be offered to females aged 14 to 26 years. Ongoing research will determine the duration of protection conferred by the vaccine, and the potential need for booster doses. In conjunction with continued screening programs, the HPV vaccine offers the potential to dramatically reduce the burden of cervical cancer in Canada, and to do so in a cost-effective manner.
