Examining the Stability and Durability of Child Care Arrangements during the COVID-19 Pandemic in Canada
Authors: Hacioglu Busra , Burns Samantha , Davidson Adrienne , Perlman Michal , White Linda A. 
Published: June 2024

La pandémie de COVID-19 a provoqué d'importantes perturbations dans tous les secteurs du travail et de la vie familiale, y compris les services de garde éducatifs à l'enfance (SGÉE). Les recherches démontrent que l'instabilité (soit les interruptions aux services de garde) et l'absence de durabilité des SGÉE (soit le maintien des mêmes services de garde au fil du temps) peuvent exacerber le stress des parents et nuire au développement de l'enfant. S'inspirant des données d'un sondage original réalisé en décembre 2020 auprès de 882 parents de jeunes enfants de quatre provinces canadiennes, les autrices ont examiné les choix des parents au sujet de la garde d'enfants avant la pandémie et les répercussions de la COVID-19 sur ces dispositions, dans l'immédiat et à long terme. Dans leur échantillon, elles ont trouvé que a) les services hors du domicile étaient plus instables et plutôt moins durables que ceux à domicile; b) la perte d'accès pendant la pandémie à cause de la fermeture des centres de la petite enfance était moins marquée en Colombie-Britannique, ce qui était toutefois contrebalancé par un taux relativement élevé de retraits volontaires; c) l'Ontario a présenté un taux relativement élevé de pertes d'accès en raison des fermetures et des retraits volontaires; d) dans l'ensemble, 64 % des dispositions en matière de garde se sont révélées durables, mais e) la durabilité était plus faible dans les familles à plus faible revenu et en Ontario. En revanche, la durabilité était beaucoup plus élevée au Québec, ce qui fait ressortir le rôle possible des investissements dans les politiques des SGÉE pour protéger les parents et les enfants en cas d’événements déstabilisants.

Published: June 2024

Background: Evidence from previous observational studies suggest that infection by herpes simplex virus (HSV) and varicella zoster virus (VZV) increase the risk of dementia. Objective: To investigate if older adults exposed to HSV treatment have lower risk of dementia than the rest of the population. Methods: We used the 10% Australian Pharmaceutical Benefits Scheme (PBS) database from 2013 to 2022 to ascertain the cross-sectional, time-series and longitudinal association between exposure to HSV treatment and the dispensing of antidementia medicines. Participants were men and women aged 60 years or older. We used Anatomical Therapeutic Chemical (ATC) codes to identify medicines dispensed for the treatment of HSV and dementia. Results: During the year 2022 6,868 (1.2%) of 559,561 of participants aged 60 years or over were dispensed antidementia agent. The odds ratio (OR) of being dispensed an antidementia agent among individuals dispensed treatment for HSV was 0.73 (99% CI = 0.56–0.95). Multilevel logistic regression for the 2013–2022 period for those dispensed HSV treatment was 0.87 (99% CI = 0.75–1.00). Split-time span series from 2013 was associated with hazard ratio of 0.98 (99% CI = 0.89–1.07) for individuals dispensed relative to those not dispensed HSV treatment. All analyses were adjusted for age, sex, and the dispensing of medicines for the treatment of diabetes, hyperlipidemia, hypertension, and ischemic heart disease. Conclusions: The dispensing of antiviral medicines for the treatment of HSV and VZV is consistently, but not conclusively, associated with decreased dispensing of antidementia medicines. This suggests that treatment of HSV and VZV infections may contribute to reduce the risk of dementia.

Published: June 2024

Background: People with Parkinson’s disease (PwPD) exhibit various sexual difficulties (SDs) that may be due to motor and/or nonmotor symptoms or the use of antiparkinsonian medication. SDs are often underreported by PwPD and underexplored by physicians. Objective: This study aimed to explore the SDs experienced by PwPD and create a scale for assessing them. Methods: A corpus of items was generated from semistructured interviews to represent the experience of PwPD as closely as possible. The number of items was reduced according to the psychometric properties, and the scale’s structure was subsequently examined. The final phase consisted of measuring the scale’s validity and reliability. Results: After assessment of the original corpus of 59 items by PwPD and clinicians, a 25-item version was obtained. The analysis of item properties led to the removal of fifteen items. An exploratory factor analysis of the first 10-item version with a first PwPD sample identified four components of the SDs among PwPD: “low sexual esteem,” “sexual displeasure,” “impact on sexual position” and “hypersexuality.” With a second PwPD sample, a confirmatory factor analysis demonstrated a satisfactory fit between the model with four components and the data. The 10-item scale had good internal consistency and good temporal reliability. Conclusions: The Parkinson’s Disease Sexual Difficulties Scale (PD-SDS) is a valid screening tool that facilitates the investigation of and communication about PD-related SDs. It is intended to improve the identification of vulnerable PwPD and to target the domain of sexual experience impacted by PD to better support PwPD.

Published: June 2024

Background: The serotonin (5-HT) system can manipulate the processing of exogenous L-DOPA in the DA-denervated striatum, resulting in the modulation of L-DOPA-induced dyskinesia (LID). Objective: To characterize the effects of the serotonin precursor 5-hydroxy-tryptophan (5-HTP) or the serotonin transporter (SERT) inhibitor, Citalopram on L-DOPA-induced behavior, neurochemical signals, and underlying protein expressions in an animal model of Parkinson’s disease. Methods: MitoPark (MP) mice at 20 weeks of age, subjected to a 14-day administration of L-DOPA/Carbidopa, displayed dyskinesia, referred to as LID. Subsequent investigations explored the effects of 5-HT-modifying agents, such as 5-HTP and Citalopram, on abnormal involuntary movements (AIMs), locomotor activity, neurochemical signals, serotonin transporter activity, and protein expression in the DA-denervated striatum of LID MP mice. Results: 5-HTP exhibited duration-dependent suppressive effects on developing and established LID, especially related to abnormal limb movements observed in L-DOPA-primed MP mice. However, Citalopram, predominantly suppressed abnormal axial movement induced by L-DOPA in LID MP mice. We demonstrated that 5-HTP could decrease L-DOPA-upregulation of DA turnover rates while concurrently upregulating 5-HT metabolism. Additionally, 5-HTP was shown to reduce the expressions of p-ERK and p-DARPP-32 in the striatum of LID MP mice. The effect of Citalopram in alleviating LID development may be attributed to downregulation of SERT activity in the dorsal striatum of LID MP mice. Conclusions: While both single injection of 5-HTP and Citalopram effectively mitigated the development of LID, the difference in mitigation of AIM subtypes may be linked to the unique effects of these two serotonergic agents on L-DOPA-derived DA and 5-HT metabolism.

Published: June 2024

OBJECTIVES: Perinatal asphyxia is the main risk factor for mortality and morbidity in neonates and neurological disorders in survived infants. We compared the neonatal and maternal 25 (OH) vitamin D levels in neonates with/without asphyxia. MATERIALS AND METHODS: This cross-sectional research was done on 229 neonates (including 158 neonates [69%] without asphyxia [control group] and 71 neonates [31%] with asphyxia [case group]) from 2020 to 2023 using the available sampling method. 25 (OH) Vit D levels in mothers and neonates were assessed and compared in the 2 groups. The data collection instrument was a researcher-made checklist, containing the maternal and neonatal characteristics and laboratory evaluations. Data were analyzed by SPSS 23 using the t-test. RESULTS: The mean maternal 25 (OH) Vit D levels in the case and control groups were 16.34±11.87 and 22.80±12.67 ng/mL, respectively. The mean neonatal 25 (OH) Vit D levels in the case and control groups were respectively 12.13±8.62 and 19.55±11.62 ng/mL ( P = 0.002). The case group showed severer maternal and neonatal 25 (OH) Vit D deficiency ( P = 0.000) compared to the control group. CONCLUSIONS: Neonatal and maternal 25 (OH) Vit D deficiency can increase the risk of perinatal asphyxia. Therefore, administration of 25 (OH) Vit D supplements to pregnant mothers may reduce the incidence of asphyxia.

Published: June 2024

BACKGROUND: Fetal inflammatory response syndrome (FIRS), the fetal equivalent of chorioamnionitis, is associated with poorer neonatal outcomes. FIRS is diagnosed through placental histology, namely by the identification of funisitis (inflammation of the umbilical cord) and chorionic vasculitis (inflammation of fetal vessels within the chorionic plate). The aim of this study was to identify and evaluate associations between FIRS and neonatal outcomes in preterm neonates. METHODS: We performed a retrospective cohort study at a level III neonatal intensive care unit (NICU), from January 1st 2008 to December 31st 2022, involving all inborn neonates with a gestational age below 30 weeks. We compared preterm neonates based on whether their placental histology described funisitis with chorionic vasculitis (FCV) or not. RESULTS: The study included 113 preterms, 27 (23.9%) of those had FCV and 86 (76.1%) did not. After adjusting to gestational age, prolonged rupture of membranes and preeclampsia, FCV was independently associated with the development of early-onset sepsis (OR = 7.3, p = 0.021) and cystic periventricular leukomalacia (OR = 4.6, p = 0.004). CONCLUSION: The authors identified an association between FIRS and the development of early-onset sepsis and cystic periventricular leukomalacia, highlighting the importance of early detection and management of this condition in order to improve long-term neonatal outcomes.

This study aims to investigate the influence of steam curing on the performance of high-strength concrete incorporating metakaolin. An experimental study was conducted to investigate the compressive strength, chloride permeability, initial surface absorption, and water absorption, as well as thermal degradation under various steam curing scenarios. Four concrete mixtures were prepared in this study, each with different percentages of metakaolin, as partial substitution of cement weight of 0%, 5%, 10%, and 15%. The water–binder ratio was set to 0.32 in all mixtures. The specimens underwent steam curing for 0, 4, 8, and 16 hours at a temperature of 55 °C. Results indicate that the specimens that have been steam cured and contained metakaolin exhibit improved compressive strength during the initial stages of their strength development. Steam curing has been demonstrated to enhance the concrete’s resistance to chloride penetration and reduce initial surface absorption while increasing water absorption. The optimal replacement of cement with metakaolin to enhance strength and transport properties in high-strength concrete under steam curing regimes is between 10% and 15%. Future research could examine the effects of long-term steam curing on the durability and performance of concrete incorporating an optimal proportion of metakaolin.

IntroductionCompared to households not managing food allergy, households managing food allergy are faced with greater direct and indirect costs. To address these cost burdens, we developed and piloted a milk allergy-friendly food supplement program for lower- and middle-income households managing a dairy allergy in a child age &lt;6 years. Herein, we aimed to evaluate to the impact of this program on food costs, food security, and caregiver mental health using a longitudinal design.MethodsParticipants living in or near the city of Winnipeg, in Manitoba, Canada were recruited from January to February 2022 via social media, word-of-mouth, and a database maintained by the principal investigator. Consenting participants took part in a 6-month allergen-friendly food supplement program that provided them with biweekly deliveries of allergen-friendly foods free of charge. To evaluate the impact of the program on food costs, food security, and well-being, participants completed a series of questionnaires at baseline, mid-point, and at the end of the program. Changes in these variables were assessed via a series of Friedman tests.ResultsThe final sample was comprised of 8 households. Relative to baseline, participants reported higher total direct food costs at midpoint (+5.6%) and endpoint (+13.5%), but these changes did not reach statistical significance. In contrast, total indirect food costs decreased over the course of the study relative to baseline (midpoint = −28.2%; endpoint = −18.5%), but the changes were not found to be statistically significant. Participants did, however, report a statistically significant decrease in costs related to lost time from work or school as a result of their child's food allergy at endpoint relative to baseline (−100%). Few changes in food security, caregiver well-being, or child food allergy quality of life were noted.DiscussionThe provision of allergen-friendly foods helped keep grocery costs below the pace of inflation. Participants also reported reduced costs associated with missed time from work or school as a result of their child's food allergy. Despite these encouraging findings, a relatively high proportion of the current sample reported experiencing food insecurity throughout the study period, suggesting that additional financial support for families is needed.
