Objectives: Beginning early in the pandemic, there was a worldwide effort to develop effective vaccines against the SARS-CoV-2 virus. Before and after the approval and implementation of vaccines, there were concerns about their need as well as their safety and rapid development. We explored child demographic characteristics and parental concerns to identify factors associated with the decision to vaccinate. Methods: A cohort of 1035 children from Calgary was assembled in 2020 to participate in 5 visits every 6 months for survey completion and blood sampling for SARS-CoV-2 antibodies. Visits 1 to 2 occurred before approval of vaccines for children; Visits 3 to 5 occurred after vaccine approval for different age groups. We described vaccine concerns and utilized logistic regression to examine factors associated with the decision to vaccinate in children ≥5 years of age. Results: Children ≥12 years of age, of non-white or non-black ethnicity, and who had received previous influenza vaccines had higher odds of being vaccinated against SARS-CoV-2. Children with previous SARS-CoV-2 infection had lower odds of being vaccinated. The most common concerns in early 2021 were about vaccine safety. By summer 2022, the most common concern was a belief that vaccines were not necessary. Through the study 88% of children were vaccinated. Conclusions: Age, ethnicity, previous infections, and vaccine attitudes were associated with parental decision to vaccinate against SARS-CoV-2. For children who remained unvaccinated, parents continued to have safety concerns and questioned the necessity of the vaccine. Complacency about the need for vaccination may be more challenging to address and overcome than concerns about safety alone.

BACKGROUND: The continued increase in global migration compels clinicians to be aware of specific health problems faced by refugees, immigrants, and migrants (RIM). This analysis aimed to characterize RIM evaluated at GeoSentinel sites, their migration history, and infectious diseases detected through screening and diagnostic workups. METHODS: A case report form was used to collect data on demographics, migration route, infectious diseases screened, test results, and primary infectious disease diagnosis for RIM patients seen at GeoSentinel sites. Descriptive statistics were performed. RESULTS: Between October 2016 and November 2018, 5,319 RIM patients were evaluated at GeoSentinel sites in 19 countries. Africa was the region of birth for 2,436 patients (46 %), followed by the Americas (1,644, 31 %), and Asia (1,098, 21 %). Tuberculosis (TB) was the most common infection screened and reported as positive (853/2,273, 38 % positive by any method). TB, strongyloidiasis, and hepatitis B surface antigen positivity were observed across all migration administrative categories and regions of birth. Chagas disease was reported only among RIM patients from the Americas (393/394, 100 %) and schistosomiasis predominantly in those from Africa (480/510, 94 %). TB infection (694/5,319, 13 %) and Chagas disease (524/5,319, 10 %) were the leading primary infectious disease diagnoses. CONCLUSIONS: Several infections of long latency (e.g. TB, hepatitis B, and strongyloidiasis) with potential for long-term sequelae were seen among RIM patients across all migration administrative categories and regions of origin. Obtaining detailed epidemiologic information from RIM patients is critical to optimize detection of diseases of individual and public health importance, particularly those with long latency periods.

Atovaquone-proguanil (AP) is used as treatment for uncomplicated malaria, and as a chemoprophylactic agent against Plasmodium falciparum. Imported malaria remains one of the top causes of fever in Canadian returning travelers. Twelve sequential whole-blood samples before and after AP treatment failure were obtained from a patient diagnosed with P. falciparum malaria upon their return from Uganda and Sudan. Ultradeep sequencing was performed on the cytb, dhfr, and dhps markers of treatment resistance before and during the episode of recrudescence. Haplotyping profiles were generated using three different approaches: msp2-3D7 agarose and capillary electrophoresis, and cpmp using amplicon deep sequencing (ADS). A complexity of infection (COI) analysis was conducted. De novo cytb Y268C mutants strains were observed during an episode of recrudescence 17 days and 16 h after the initial malaria diagnosis and AP treatment initiation. No Y268C mutant reads were observed in any of the samples prior to the recrudescence. SNPs in the dhfr and dhps genes were observed upon initial presentation. The haplotyping profiles suggest multiple clones mutating under AP selection pressure (COI > 3). Significant differences in COI were observed by capillary electrophoresis and ADS compared to the agarose gel results. ADS using cpmp revealed the lowest haplotype variation across the longitudinal analysis. Our findings highlight the value of ultra-deep sequencing methods in the understanding of P. falciparum haplotype infection dynamics. Longitudinal samples should be analyzed in genotyping studies to increase the analytical sensitivity.

BACKGROUND: Measurement of SARS-CoV-2 antibody seropositivity is important to accurately understand exposure to infection and/or vaccination in specific populations. This study aimed to estimate the serologic response to SARS-CoV-2 virus infection and vaccination in children in Calgary, Alberta over a two-year period. METHODS: Children with or without prior SARS-CoV-2 infections, were enrolled in Calgary, Canada in 2020. Venous blood was sampled 4 times from July 2020 to April 2022 for SARS-CoV-2 nucleocapsid and spike antibodies. Demographic and clinical information was obtained including SARS-CoV-2 testing results and vaccination records. RESULTS: 1035 children were enrolled and 88.9% completed all 4 visits; median age 9 years (IQR: 5,13); 519 (50.1%) female; and 815 (78.7%) Caucasian. Before enrolment, 118 (11.4%) had confirmed or probable SARS-CoV-2. By April 2022, 39.5% of previously uninfected participants had a SARS-CoV-2 infection. Nucleocapsid antibody seropositivity declined to 16.4% of all infected children after more than 200 days post diagnosis. Spike antibodies remained elevated in 93.6% of unvaccinated infected children after more than 200 days post diagnosis. By April 2022, 408 (95.6%) children 12 years and older had received 2 or more vaccine doses, and 241 (61.6%) 5 to 11 year-old children had received 2 vaccine doses. At that time, all 685 vaccinated children had spike antibodies, compared with 94/176 (53.4%) of unvaccinated children. CONCLUSIONS: In our population, after the first peak of Omicron variant infections and introduction of COVID-19 vaccines for children, all vaccinated children, but just over one-half of unvaccinated children, had SARS-CoV-2 spike antibodies indicating infection and/or vaccination, highlighting the benefit of vaccination. It is not yet known whether a high proportion of seropositivity at the present time predicts sustained population-level protection against future SARS-CoV-2 transmission, infection or severe COVID-19 outcomes in children.

BACKGROUND: Travelling for medical care is increasing, and this medical tourism (MT) may have complications, notably infectious diseases (ID). We sought to identify MT-related infections (MTRIs) in a large Canadian health region and estimate resulting costs. METHODS: Retrospective and prospective capture of post-MT cases requiring hospital admission or outpatient parenteral antimicrobial therapy was completed by canvassing ID physicians practising in Calgary, Alberta, from January 2017 to July 2019. Cost estimates for management were made with the Canadian Institute for Health Information's (CIHI's) patient cost estimator database tool applied to estimated rates of Canadians engaging in MT from a 2017 Fraser Institute report. RESULTS: We identified 12 cases of MT-related infectious syndromes. Eight had microbial etiologies identified. MTs were young (mean 40.3 [SD 12.2] y) and female (n = 11) and pursued surgical treatment (n = 11). Destination countries and surgical procedures varied but were largely cosmetic (n = 5) and orthopaedic (n = 3). Duration to organism identification (mean 5.3 wk) and treatment courses (mean 19 wk) appeared lengthy. CIHI cost estimates for management of relevant infectious complications of our cases ranged from $6,288 to $20,741, with total cost for cases with matching codes (n = 8) totalling $94,290. CONCLUSIONS: In our series of MTRIs, etiologic organisms often found in Canadian-performed post-procedural infections were identified, and prolonged treatment durations were noted. Young women pursuing cosmetic surgery may be a population to target with public health measures to reduce the incidence of MTRIs and burden of disease.


HISTORIQUE: Le nombre de voyages pour obtenir des soins médicaux augmente, et ce tourisme médical (TM) peut être la source de complications, notamment de maladies infectieuses (MI). Les chercheurs ont entrepris de colliger les infections liées au TM (ILTM) dans une grande région sociosanitaire canadienne et d'en estimer les coûts. MÉTHODOLOGIE: Pour procéder à la saisie rétrospective et prospective des cas exigeant une hospitalisation ou un traitement antimicrobien parentéral ambulatoire après le TM, les chercheurs ont sondé les infectiologues d'une grande région sociosanitaire canadienne entre janvier 2017 et juillet 2019. Ils ont évalué les coûts du traitement de ces cas à l'aide de l'outil de la base de données d'évaluation des coûts des patients de l'Institut canadien d'information sur la santé (ICIS), qu'ils ont appliqué aux taux estimatifs de Canadiens qui avaient fait du TM d'après le rapport de l'Institut Fraser de 2017. RÉSULTATS: Les chercheurs ont détecté 12 cas de syndromes infectieux liés au TM, dont huit étaient rattachés à une étiologie microbienne connue. Les touristes médicaux étaient de jeunes (moyenne de 40,3 [ÉT = 12,2] ans) femmes (n = 11) qui voulaient subir une intervention chirurgicale (n = 11). Les destinations et les interventions chirurgicales variaient, mais elles étaient surtout esthétiques (n = 5) et orthopédiques (n = 3). La période avant d'identifier l'organisme (moyenne de 5,3 semaines) et la durée du traitement (moyenne de 19 semaines) semblaient longues. L'ICIS a estimé que les coûts de prise en charge des complications infectieuses pertinentes des cas se situent entre 6 288 $ à 20 741 $, le coût de tous les cas correspondant à un code (n = 8) totalisant 94 290 $. CONCLUSIONS: Dans la série d'ILTM, les chercheurs ont détecté des organismes étiologiques souvent constatés après une intervention réalisée au Canada et ont remarqué que le traitement était plus long. Les jeunes femmes qui veulent subir des interventions de chirurgie esthétique pourraient être une population ciblée pour transmettre des mesures sanitaires, afin de réduire l'incidence d'ILTM et le fardeau de la maladie.

INTRODUCTION: Many families express hesitancy around immunizing their children against COVID-19. We sought to better understand the perspectives of vaccine hesitant caregivers, and develop targeted recommendations for health care workers and policymakers to engage in more effective vaccine discussions. METHODS: We conducted semi-structured telephone interviews with 23 caregivers recruited from a pediatric infectious diseases clinic, including a subset of patients referred to discuss vaccine hesitancy. Thematic analysis of the interviews identified themes that were mapped using behavior change models to identify perceived barriers and facilitators towards COVID-19 immunization. RESULTS: Barriers and facilitators were mapped to the WHO (World Health Organization) 3C's (confidence, complacency, convenience) model of vaccine hesitancy as well as the COM-B (capability, opportunity, motivation) behavior change model. Barriers included mistrust in authorities, misperception of the risk of COVID-19 in children, and perceived health contraindications and negative previous vaccine experiences. Facilitators included positive relationships with healthcare workers, the promise of a "return to normal", and societal pressures to immunize. CONCLUSIONS: Efforts to increase vaccine uptake in the pediatric population must target specific barriers and facilitators to immunization expressed by caregivers. To address these concerns, we suggest: 1. Educating hesitant caregivers by highlighting the long-term pandemic effects on children and the threat of COVID-19 to children's health, 2. Building on the trust caregivers have in healthcare workers by involving frontline workers in public health policy, and 3. Harnessing the power of peer pressure by mobilization of societal pressures and establishing COVID-19 vaccination as the norm in children.

Emergomyces canadensis pulmonary infection was incidentally diagnosed in an asymptomatic patient suspected to have metastatic osteosarcoma. Molecular diagnosis was imperative to fungal identification given overlapping histopathological features with histoplasmosis. This report documents a case of isolated pulmonary emergomycosis in an otherwise immunocompetent patient while discussing diagnostic and management pitfalls of this emerging and underdiagnosed infection.

BACKGROUND: Compassion has received significant scholarly attention over the past decade. Research has been largely theoretical, with interventions focused on self-care practices of healthcare providers (HCPs), rather than implementation at a systems level. This study aimed to identify how compassion can be operationalized within pediatric healthcare. DESIGN AND METHODS: Data was analyzed from a secondary dataset of a larger Straussian grounded theory study of perspectives and experiences of compassion in pediatric healthcare. Patients (n = 33); parents (n = 16); and HCPs (n = 17) were asked specifically how compassion could be implemented within the clinical culture and healthcare system. RESULTS: 66 participants generated an operational model of compassion indicating how compassion could be implemented across the organization and larger healthcare system. The data revealed four themes and associated subthemes: teach and train; recognize and reward; measure and report; and embed compassion across the healthcare system. CONCLUSIONS: Improving compassion in pediatric healthcare needs to extend beyond the efforts of individual HCPs. Compassion is the responsibility of the entire healthcare system and needs to traverse the patient and family experience. In addition to embedding compassion in policy, procedures, practice, and education, compassion should be considered a performance indicator that is measured and reported. PRACTICE IMPLICATIONS: This study provides a preliminary framework for organizational leaders to operationalize compassion across the services, structures, polices, procedures and practices of pediatric healthcare. This includes ongoing compassion training across the organization; assessing compassion, recognizing compassion as a performance indicator, and ensuring that the infrastructure and ancillary services of the organization reflect compassion.

BACKGROUND: Neuromyelitis Optica Spectrum Disorder can be associated with parainfectious and post-infectious triggers. Dengue virus infection is one of the most common arbovirus infections in the world, and may present with neurological manifestations. OBJECTIVES: We present a case of DENV-associated with LETM and positive aquaporin-4 IgG, and a systematic review of published cases. METHODS: Medline (Ovid) and PubMed were search through June 2021, for case reports, series and observational studies that described patients with DENV-associated LETM and/or NMOSD. RESULTS: An adolescent girl who had recently immigrated from a Dengue-endemic region presented with a LETM with high positive AQP4-IgG titer and seropositive DENV IgM/IgG antibodies. She responded well to steroids and subsequently started maintenance rituximab for her NMOSD diagnosis. LITERATURE REVIEW: 22 publications describing 27 patients met inclusion criteria. In addition to this case, three published cases met current criteria for NMOSD with serological evidence of acute DENV infection. CONCLUSIONS: It is unknown whether there is a pathophysiological association between DENV infection and NMOSD. Regardless, if an immune-mediated event is suspected, particularly NMOSD, appropriate immunotherapy should be considered early. Decision regarding long term immunotherapy may depend on index of suspicion of true NMOSD, and this is where AQP4-IgG status and follow-up is helpful.

BACKGROUND: Maternal and newborn mortality is high immediately after childbirth and up to 42 days postnatally despite the availability of interventions. Postnatal care is crucial in preventing mortality and improving the health of women and newborns. This prospective cohort study investigated the initiation and utilization of postnatal care at health facilities and explored users' and providers' perspectives on utilization of postnatal care services. METHODS: A sequential explanatory mixed method was used involving women who were followed from the 3rd trimester of pregnancy to 3-4 months postnatally in Northwest, Tanzania. From January to December 2018, a door-to-door survey was conducted 3-4 months postnatally among 1385 of these women. A convenience sample of women and community health workers participated in focus group discussions, and traditional birth attendants and nurses participated in key informant interviews to complement quantitative data. Data analyses were conducted using STATA version 13 and NVIVO version 12. STUDY FINDINGS: Approximately, one half of participants attended postnatal care within 42 days after delivery. Postnatal care seeking within 48 h after delivery was reported by 14.6 % of the participants. Women who attended antenatal care at least four times, delivered at health facilities or experienced delivery-related complications were more likely to seek postnatal care. Limited knowledge on the postnatal care services and obstetric complications after childbirth, and not being scheduled for postnatal care by health providers negatively influenced services uptake. Overwhelming workload and shortages of supplies were reported to hinder the provision of postnatal care services. CONCLUSIONS: Utilization of postnatal care services remains low in this setting as a result of a number of disparate and complex factors that influence women's choices. Provision of effective postnatal care is hindered by lack of supplies, staffing, and inadequate infrastructure. To ensure accessibility and availability of quality services in this setting, both demand and supply sides factors need to be addressed.

OBJECTIVE: Compassion has long been considered a cornerstone of quality pediatric healthcare by patients, parents, healthcare providers and systems leaders. However, little dedicated research on the nature, components and delivery of compassion in pediatric settings has been conducted. This study aimed to define and develop a patient, parent, and healthcare provider informed empirical model of compassion in pediatric oncology in order to begin to delineate the key qualities, skills and behaviors of compassion within pediatric healthcare. METHODS: Data was collected via semi-structured interviews with pediatric oncology patients (n = 33), parents (n = 16) and healthcare providers (n = 17) from 4 Canadian academic medical centers and was analyzed in accordance with Straussian Grounded Theory. RESULTS: Four domains and 13 related themes were identified, generating the Pediatric Compassion Model, that depicts the dimensions of compassion and their relationship to one another. A collective definition of compassion was generated-a beneficent response that seeks to address the suffering and needs of a person and their family through relational understanding, shared humanity, and action. CONCLUSIONS: A patient, parent, and healthcare provider informed empirical pediatric model of compassion was generated from this study providing insight into compassion from both those who experience it and those who express it. Future research on compassion in pediatric oncology and healthcare should focus on barriers and facilitators of compassion, measure development, and intervention research aimed at equipping healthcare providers and system leaders with tools and training aimed at improving it.

BACKGROUND: In low and middle-income countries, pregnancy and delivery complications may deprive women and their newborns of life or the realization of their full potential. Provision of quality obstetric emergency and childbirth care can reduce maternal and newborn deaths. Underutilization of maternal and childbirth services remains a public health concern in Tanzania. The aim of this study was to explore elements of the local social, cultural, economic, and health systems that influenced the use of health facilities for delivery in a rural setting in Northwest Tanzania. METHODS: A qualitative approach was used to explore community perceptions of issues related to low utilization of health facilities for childbirth. Between September and December 2017, 11 focus group discussions were conducted with women (n = 33), men (n = 5) and community health workers (CHWs; n = 28); key informant interviews were conducted with traditional birth attendants (TBAs; n = 2). Coding, identification, indexing, charting, and mapping of these interviews was done using NVIVO 12 after manual familiarization of the data. Data saturation was used to determine when no further interviews or discussions were required. RESULTS: Four themes emerge; self-perceived obstetric risk, socio-cultural issues, economic concerns and health facility related factors. Health facility delivery was perceived to be crucial for complicated labor. However, the idea that childbirth was a "normal" process and lack of social and cultural acceptability of facility services, made home delivery appealing to many women and their families. In addition, out of pocket payments for suboptimal quality of health care was reported to hinder facility delivery. CONCLUSION: Home delivery persists in rural settings due to economic and social issues, and the cultural meanings attached to childbirth. Accessibility to and affordability of respectful and culturally acceptable childbirth services remain challenging in this setting. Addressing barriers on both the demand and supply side could result in improved maternal and child outcomes during labor and delivery.

INTRODUCTION: International travellers contribute to the rapid spread of Zika virus (ZIKV) and its sentinel identification globally. We describe ZIKV infections among international travellers seen at GeoSentinel sites with a focus on ZIKV acquired in the Americas and the Caribbean, describe countries of exposure and traveller characteristics, and assess ZIKV diagnostic testing by site. METHODS: Records with an international travel-related diagnosis of confirmed or probable ZIKV from January 2012 through December 2019 reported to GeoSentinel with a recorded illness onset date were included to show reported cases over time. Records from March 2016 through December 2019 with an exposure region of the Americas or the Caribbean were included in the descriptive analysis. A survey was conducted to assess the availability, accessibility and utilization of ZIKV diagnostic tests at GeoSentinel sites. RESULTS: GeoSentinel sites reported 525 ZIKV cases from 2012 through 2019. Between 2012 and 2014, eight cases were reported, and all were acquired in Asia or Oceania. After 2014, most cases were acquired in the Americas or the Caribbean, a large decline in ZIKV cases occurred in 2018-19.Between March 2016 and December 2019, 423 patients acquired ZIKV in the Americas or the Caribbean, peak reporting to these regions occurred in 2016 [330 cases (78%)]. The median age was 36 years (range: 3-92); 63% were female. The most frequent region of exposure was the Caribbean (60%). Thirteen travellers were pregnant during or after travel; one had a sexually acquired ZIKV infection. There was one case of fetal anomaly and two travellers with Guillain-Barré syndrome. GeoSentinel sites reported various challenges to diagnose ZIKV effectively. CONCLUSION: ZIKV should remain a consideration for travellers returning from areas with risk of ZIKV transmission. Travellers should discuss their travel plans with their healthcare providers to ensure ZIKV prevention measures are taken.

BACKGROUND: Reports relying on population-based data and using epidemiologic methodologies such as case-control study designs for malaria in travellers and multivariable regression analysis of risk factors are rare. The aim of this study was to investigate the epidemiologic characteristics of travellers who tested positive for malaria after visiting friends and relatives in malaria-endemic areas to determine the risk of malaria associated with such travel. METHODS: Using routinely collected data from a population-based laboratory database, we conducted a case-control study of symptomatic people returning from travel to malaria-endemic areas who presented for malaria testing in Calgary from 2013 to 2017. We used a multivariable logistic regression to analyze the association between the presence of malaria and other risk factors. RESULTS: There were 251 confirmed malaria cases during the study period, of which 219 were matched to 1129 returning travellers without malaria. Based on the multivariable regression, the odds of a traveller who visited friends and relatives in malariaendemic areas being diagnosed with malaria was 2.82 (95% confidence interval [CI] 1.42-5.92) times greater than that of other travellers to these regions. Adults (odds ratio [OR] 3.62, 95% CI 1.66-8.84), males (OR 2.70, 95% CI 1.56-4.80), travellers to Africa (OR 11.52, 95% CI 6.33-22.05) and those who did not seek pretravel advice (OR 0.38, 95% CI 0.20-0.70) were more likely to be diagnosed with malaria. Although those travelling to visit friends and relatives tended to stay longer in endemic areas than other travellers, visit duration was not associated with an increased likelihood of malaria in the model. The annual incidence of malaria was highest (13.34 per 100 000) in metropolitan wards associated with lower socioeconomic status and immigrant communities. INTERPRETATION: Travellers who visited friends and relatives in malaria-endemic areas were less likely than other travellers to these regions to seek pretravel advice, take prophylaxis and have a visit duration less than 2 weeks; travelling to Africa and being male increased the odds of being diagnosed with malaria, independent of other factors. These data suggest that targeted strategies to provide pretravel care to travellers who visit friends and relatives in malaria-endemic areas may aid in reducing the burden of malaria in this population.

PROBLEM: Compassion has been described as a central construct or essential feature of quality healthcare and is as important to patients' and families' overall healthcare experience as the health interventions and treatments they receive. However, there is little shared understanding of what constitutes compassion, how it is delivered within a pediatric setting, and pediatric patients' and families perspectives and preferences for receiving it. ELIGIBILITY CRITERIA: Studies that (1) described the nature of the existing literature on compassion in pediatric healthcare; (2) summarized key concepts in the existing evidence base that pertain to compassion in pediatric healthcare; and 3) identified factors that are associated with compassion in pediatric healthcare were eligible for inclusion in this review. SAMPLE: Twenty-nine papers were included in the review. RESULTS: Findings revealed several factors are associated with compassion in pediatric healthcare, including continuity of care, communication, and coordination of care. Most notably, identified studies treated compassion in a subsidiary fashion, and this review revealed no studies that provided a patient-informed evidence-based definition of compassion in the pediatric healthcare setting. CONCLUSION: Future research is required to generate a comprehensive and accurate understanding of the terms 'compassion' and 'compassionate care' when used in the context of pediatric healthcare. IMPLICATIONS: This research will inform the therapeutic processes and ultimately enable the development of strategies to improve the delivery of compassionate healthcare to pediatric patients.

BACKGROUND: Due to ongoing political instability and conflict in many parts of the world, migrants are increasingly seeking asylum and refuge in Canada. METHODS: We examined demographic and travel correlates of illnesses among migrants to Canada to establish a detailed epidemiologic framework of this population for Canadian practitioners. Data on ill-returned Canadian travellers presenting to a CanTravNet site between 1 January 2015 and 31 December 2015 were analyzed. RESULTS: During the study period, 2415 ill travellers and migrants presented to a CanTravNet site, and of those, 519 (21.5%) travelled for the purpose of migration. Sub-Saharan Africa (n = 160, 30.8%), southeast Asia (n = 84, 16.2%) and south central Asia (n = 75, 14.5%) were the most common source regions for migrants, while the top specific source countries, of 98 represented, were the Philippines (n = 45, 8.7%), China (n = 36, 6.9%) and Vietnam (n = 31, 6.0%). Compared with non-migrant travellers, migrants were more likely to have a pre-existing immunocompromising medical condition, such as HIV or diabetes mellitus (P < 0.0001), and to require inpatient management of their illness (P < 0.0001). Diagnoses such as tuberculosis (n = 263, 50.7%), hepatitis B and C (n = 78, 15%) and HIV (n = 11, 2.1%) were over-represented in the migrant population compared with non-migrant travellers (P < 0.0001). Most cases of tuberculosis in the migrant population (n = 263) were latent (82% [n = 216]); only 18% (n = 47) were active. CONCLUSIONS: Compared with non-migrant travellers, migrants were more likely to present with a communicable infectious disease, such as tuberculosis, potentially complicated by an underlying immunosuppressing condition such as HIV. These differences highlight the divergent healthcare needs in the migrant population, and underscore the importance of surveillance programmes to understand their burden of illness. Intake programming should be adequately resourced to accommodate the medical needs of this vulnerable population of new Canadians.

BACKGROUND: Data on the serologic status of childhood vaccines, cytomegalovirus (CMV) and Epstein-Barr virus (EBV), are limited in inflammatory bowel disease (IBD). Therefore, we evaluated vaccine coverage and seroprotection, along with CMV and EBV seropositivity, in pediatric IBD. METHODS: In a cross-sectional study, demographic data, IBD history, vaccine records, and serum for antibodies against measles, mumps, rubella, diphtheria, tetanus, varicella, hepatitis B (HBV), CMV, and EBV were collected from children with IBD. We evaluated potential factors associated with serologic status. RESULTS: Of 156 subjects, vaccine coverage was up to date for age in 93.5% for measles, mumps, rubella, 95.6% for diphtheria, tetanus, pertussis, polio, hemophilus influenza B, 75.8% for HBV, and 93.5% for varicella, including past infection and vaccination. Seroprotection was present in 65.8% for measles, 60.5% for mumps, 79.1% for rubella, 79.5% for diphtheria, 80.8% for tetanus, 70.5% for varicella, and 62.8% for HBV of subjects. Older age at diagnosis was associated with seroprotection among subjects with complete HBV (odds ratio [OR], 1.20; 95% confidence interval [CI], 1.03-1.39) and rubella series (OR, 1.18; 95% CI, 1.02-1.37). Older age at serum collection was associated with seroprotection among subjects with prior varicella vaccination or infection (OR, 1.69; 95% CI, 1.33-2.15). Only 25.2% and 37.8% demonstrated seropositivity to CMV and EBV, respectively. Among subjects on immunosuppressive medications, 75.3% and 62.4% were seronegative for CMV and EBV, respectively. CONCLUSIONS: Children with IBD have low serologic protection to childhood vaccines in spite of high vaccine coverage and universal vaccinations. Children with IBD, including a large proportion on immunosuppressive medications, have low seropositivity to CMV and EBV.

BACKGROUND: Despite the significant benefits of early detection and management of pregnancy related complications during antenatal care (ANC) visits, not all pregnant women in Tanzania initiate ANC in a timely manner. The primary objectives of this research study in rural communities of Geita district, Northwest Tanzania were: 1) to conduct a population-based study that examined the utilization and availability of ANC services; and 2) to explore the challenges faced by women who visited ANC clinics and barriers to utilization of ANC among pregnant women. METHODS: A sequential explanatory mixed method design was utilized. Household surveys that examined antenatal service utilization and availability were conducted in 11 randomly selected wards in Geita district. One thousand, seven hundred and nineteen pregnant women in their 3rd trimester participated in household surveys. It was followed by focus group discussions with community health workers and pregnant women that examined challenges and barriers to ANC. RESULTS: Of the pregnant women who participated, 86.74% attended an ANC clinic at least once; 3.62% initiated ANC in the first trimester; 13.26% had not initiated ANC when they were interviewed in their 3rd trimester. Of the women who had attended ANC at least once, the majority (82.96%) had been checked for HIV status, less than a half (48.36%) were checked for hemoglobin level, and only a minority had been screened for syphilis (6.51%). Among women offered laboratory testing, the prevalence of HIV was 3.88%, syphilis, 18.57%, and anemia, 54.09%. In terms of other preventive measures, 91.01% received a tetanus toxoid vaccination, 76.32%, antimalarial drugs, 65.13%, antihelminthic drugs, and 76.12%, iron supplements at least once. Significant challenges identified by women who visited ANC clinics included lack of male partner involvement, informal regulations imposed by health care providers, perceived poor quality of care, and health care system related factors. Socio-cultural beliefs, fear of HIV testing, poverty and distance from health clinics were reported as barriers to early ANC utilization. CONCLUSION: Access to effective ANC remains a challenge among women in Geita district. Notably, most women initiated ANC late and early initiation did not guarantee care that could contribute to better pregnancy outcomes.
