Oral Health Status of Refugee Children in Montreal

Abstract

This study aimed to assess the oral health status of refugee children in comparison with that of Canadian children. In addition, we investigated the extent to which demographic factors are associated with caries experience in this population. Children with a confirmed refugee status and Canadian children (control group) matched for age and sex composed the study population. A comprehensive review of dental charts was completed to assess children's demographic data, caries experience, oral hygiene and gingival health status. The majority of refugee children had never seen a dentist before their arrival to Canada. Refugee children had significant higher dmft/DMFT scores than Canadian children (7.29 ± 5.1 and 4.47 ± 5, respectively; p < 0.0001). Furthermore, individual factors, such as refugee status (OR = 5.08; 95% CI = 2.31–11.1) and child age (OR = 2.17; 95% CI = 1.04–4.51) were significantly associated with caries experience. Access to appropriate dental care to refugee children should be a key priority for health care providers and policy makers.

Changes in responsiveness to allatostatin treatment accompany shifts in stress reactivity in young worker honey bees

Abstract

Exposing honey bees to isopentylacetate (IPA) can cause stress-related changes in learning performance. In bees of foraging age, IPA's effects on learning are mimicked by C-type allatostatins (AstCC, AstCCC) injected into the brain. Here we ask whether allatostatins induce a similar response in young (6-day-old) bees and if so, whether their effects on learning performance are modulated by queen mandibular pheromone (QMP). We found that young bees exposed to IPA responded less to the conditioned stimulus during training than controls (Type 1-like stress response). AstCC treatment induced a similar response, but only in bees maintained without QMP. Bees exposed to QMP responded to AstCC with increased odour responsiveness and odour generalisation in the 1-h memory test (Type 2-like response). Type 2-like responses could be induced also by the A-type allatostatin, AstA. However, in bees exposed to QMP, AstA-induced odour generalisation was absent. Effects of AstCCC treatment in young bees were weak, indicating that responsiveness to this peptide changes with age. Our findings are consistent with the hypothesis that honey bee allatostatins play a role in stress reactivity, but suggest in addition that allatostatin signalling is age dependent and susceptible to modulation by pheromone released by the queen bee.

Serum Concentrations of Lidocaine During Bariatric Surgery

Lidocaine has been shown to be clinically beneficial during bariatric surgery. However, information about lidocaine serum concentrations in this setting is scarce. This prospective clinical trial included 42 obese patients undergoing laparoscopic bariatric surgery. They received lidocaine based on adjusted body weight. Administration began with a 1.5 mg·kg−1 bolus of intravenous lidocaine followed by a continuous infusion of 2 mg·kg−1·hour−1. After skin closure, administration was decreased to 1 mg·kg−1·hour−1 until discharge from the recovery room. No serum concentrations of lidocaine were outside the usual accepted range (1.5–5 µg·mL−1). Accepted for publication October 3, 2018. Funding: None. The authors declare no conflicts of interest.

Comparison of Invasive and Noninvasive Blood Pressure Measurements for Assessing Signal Complexity and Surgical Risk in Cardiac Surgical Patients

BACKGROUND: Continuous arterial blood pressure (ABP) is typically recorded by placement of an intraarterial catheter. Recently, noninvasive ABP monitors have been shown to be comparable in accuracy to invasive measurements. In a previous study, we showed that the fluctuations in beat-to-beat ABP measurements were not random variations but had a complex dynamical structure, and that ABP dynamical complexity was inversely associated with surgical risk estimated using the Society of Thoracic Surgeons (STS) index. Dynamical complexity is a mathematical construct that reflects the capacity of a physiological system to adapt to stimuli. The objectives of present study were to: (1) determine whether noninvasive beat-to-beat ABP measurements also exhibit a complex temporal structure; (2) compare the complexity of noninvasive versus invasive ABP time series; and (3) quantify the relationship between the complexity of noninvasive ABP time series and the STS risk scores. METHODS: Fifteen adult patients undergoing coronary artery bypass graft, valve, or combined coronary artery bypass graft/valve surgery ;were enrolled in this observational study. Preoperative ABP waveforms were simultaneously recorded for ≥15 minutes using a radial artery catheter (invasive) and a continuous noninvasive arterial pressure monitor. Beat-to-beat systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), and mean arterial pressure (MAP) time series were extracted from the continuous waveforms. Complexity was assessed using the multiscale entropy method. The Wilcoxon signed-rank test was used to compare the mean ranks of indices derived from invasive versus noninvasive ABP time series. Spearman correlation coefficients were used to quantify the relationship between invasive and noninvasive indices. Linear regression analysis was used to quantify the association between each of the complexity indices and the STS risk scores. RESULTS: Beat-to-beat fluctuations in noninvasive ABP measurements were not random but complex; however, their degree of complexity was lower than that of fluctuations in invasively obtained ABP signals (SBP: 7.05 vs 8.66, P
