Article Synopsis
  • The study aimed to analyze how different shift-level nursing organizational factors impact the risk of nosocomial infections (NIs) in very preterm infants in NICUs.
  • Conducted from 2014 to 2018 across three tertiary NICUs in Quebec, the research included 1921 infants and used mixed-effect logistic regression to evaluate data on nursing overtime ratios (OTRs) and nursing provision ratios (NPRs).
  • Results showed that higher nursing overtime was linked to increased odds of NIs, while a higher number of actual nurses compared to recommended levels was associated with lower odds of NIs, indicating the importance of proper staffing in preventing infections.

Background: Umbilical hernia (UH) is a common pediatric condition, for which delaying surgical repair for asymptomatic UH until after age 3 is recommended due to a high incidence of spontaneous closure. We aimed to determine the adherence to guidelines, rate of urgent surgical repair, outcomes, cost, and interinstitutional referral patterns of UH repair in the province of Quebec (Canada).

Methods: This was a population-based retrospective cohort study of children 28 days to 17 years old who underwent UH repair between 2010 and 2020 using health administrative databases.

Objective:  Neonatal intensive care units (NICUs) account for over 35% of pediatric in-hospital costs. A better understanding of NICU expenditures may help identify areas of improvements. This study aimed to validate the Canadian Neonatal Network (CNN) costing algorithm for seven case-mix groups with actual costs incurred in a tertiary NICU and explore drivers of cost.

Article Synopsis
  • The study aimed to evaluate how the occupancy levels of Neonatal Intensive Care Units (NICUs) affect the discharge rates and length of stay for infants born before 33 weeks gestation.
  • Researchers analyzed data from over 3,300 premature infants admitted to five NICUs from 2014 to 2018, using statistical models to understand these associations.
  • Findings revealed that lower occupancy was linked to lower discharge likelihood, while higher occupancy led to increased chances of discharge and a shorter average length of stay.

Article Synopsis
  • The study investigates how nurse staffing levels and occupancy rates in neonatal intensive care units (NICUs) affect the health outcomes of preterm infants born before 33 weeks of gestation.
  • Researchers conducted a retrospective cohort study involving 1870 infants, finding that higher nursing ratios correlated with lower mortality/morbidity rates, while higher occupancy rates linked to increased risks.
  • The findings suggest that maintaining optimal nurse staffing and reducing overcrowding in NICUs could enhance outcomes for very preterm infants, highlighting the need for effective resource management in healthcare settings.

The paper investigates the effects of nursing overtime on nosocomial infections and medical accidents in a neonatal intensive care unit (NICU). The literature lacks clear evidence on this issue and we conjecture that this may be due to empirical and methodological factors. We model the occurrences of both events using a sample of 3979 neonates who represents over 84,846 observations (infant/days).

As human beings, we are bound by time. It is essential for daily functioning, and yet our ability to keep track of time is influenced by a myriad of factors (Block & Zakay, 1997, Psychonomic Bulletin & Review, 4[2], 184-197). First and foremost, time estimation has been found to depend on whether participants estimate the time prospectively or retrospectively (Hicks et al.

Study Objectives: Cognitive-behavioral therapy for insomnia (CBT-I) is the recommended first-line treatment for cancer-related insomnia, but its accessibility is very limited in routine care. A stepped care approach has been recommended as a cost-effective way to make CBT-I more widely accessible. However, no controlled study has yet been published about the efficacy of this approach.

Objective: Despite its high prevalence, cancer-related insomnia typically remains untreated because of a lack of access to cognitive-behavioral therapy for insomnia (CBT-I), the treatment of choice for this condition. While face-to-face CBT-I appears to be optimal in terms of efficacy, self-administered formats may be more cost-effective. The goal of this secondary analysis of a randomized clinical trial was to compare the cost-effectiveness of a professionally-based CBT-I (PCBT-I) to that of a video-based CBT-I (VCBT-I).

Subjective confidence reports are used in numerous research paradigms to examine the extent to which participants are aware of their performance in a task. By examining the discrepancy between objective performance and subjective confidence ratings, inferences can be made about the conditions in which participants have greater explicit knowledge of the representations and processes used to complete a task. In the current study, we examined the effects of prior knowledge on subjective assessments of performance using a categorisation task wherein lists of features that defined exemplars shared latent feature associations on the basis of prior knowledge or had no prior associations.

We investigate the returns to college attendance in Canada in terms of health and mortality reduction. To do so, we first use a dynamic health microsimulation model to document how interventions that incentivize college attendance among high school graduates may impact their health trajectory, health care consumption, and life expectancy. We find large returns both in terms of evity (4.

Objective: This article assesses the effect of reducing consecutive hours worked by residents from 24 to 16 hours on yearly total hours worked per resident in the neonatal intensive care unit (NICU) and evaluates the association of resident duty hour reform, level of trainee, and the number of residents present at admission with mortality in the NICU.

Study Design: This is a 6-year retrospective cohort study including all pediatric residents working in a Level 3 NICU ( = 185) and infants admitted to the NICU ( = 8,159). Adjusted odds ratios (aOR) were estimated for mortality with respect to Epoch (2008-2011 [24-hour shifts] versus 2011-2014 [16-hour shifts]), level of trainee, and the number of residents present at admission.

Function learning research has shown that people tend to underestimate positive linear functions when extrapolating Y for X-values below the training range. Kwantes and Neal (2006) proposed that this underestimation occurs because people anchor their Y-estimates at zero. It is equally plausible, however, that people are biased to make Y-estimates similar to the presented X-value.

Article Synopsis
  • - S. W. Allen and L. R. Brooks (1991) demonstrated that people's memory of specific examples (exemplar memory) can influence how they categorize new information, even if they have a classification rule to follow.
  • - G. Regehr and L. R. Brooks (1993) suggested that for this influence to happen, the stimuli (the things being categorized) need to be distinguishable from one another.
  • - The current study evaluates when exemplar effects appear in categorization with experiments showing that attention to certain interchangeable attributes is necessary for an impact, but these effects can also occur even without attention in more incidental learning conditions.

The goal of this study was to evaluate the possibility that dyslexic individuals require more working memory resources than normal readers to shift attention from stimulus to stimulus. To test this hypothesis, normal and dyslexic adolescents participated in a Rapid Serial Visual Presentation experiment (Raymond, Shapiro, & Arnell, 1992). Surprisingly, the result showed that the participants with dyslexia produced a shallower attentional blink than normal controls.
