People living with epilepsy (PWE) experience higher rates of depression compared with the general population. Depression in PWE is associated with increased seizure burden and reduced quality of life. We aimed to examine clinical and demographic correlates of depression severity using the nine-item Patient Health Questionnaire in PWE experiencing negative health events in the past 6 months.

1. (a) To assess how depressive severity correlated with seizure frequency;

2. (b) To examine how outcomes such as quality of life are influenced by depressive severity;

3. (c) To investigate how demographic factors affect depressive severity.

Depressive severity was defined as a score of 0–9 for no depression to mild symptoms (NMD), 10–19 for moderate depression (MOD) and 20–27 for severe depression. Continuous variables were analysed using the Kruskal–Wallis equality-of-populations rank test, and categorical variables were compared using Fisher’s exact test. Baseline data were taken from Sequential, Multiple Assignment Randomized Trial no. NCT04705441.

The sample of 159 participants had a mean age of 39.46 years (s.d., 12.15), with the majority (n = 131, 82.4%) identifying as White. A total of 48% (n = 76) of participants met the criteria for NMD, 41% (n = 65) met those for MOD and 11% (n = 18) met those for severe depression. The severe depression group had significantly more seizures in the past 30 days, as well as greater perceived stigma, lower social support and lower quality of life, compared with the other groups. Race was found to correlate with depressive severity in NMD and MOD versus the severe depression group.

Among adults with epilepsy, depressive severity was positively correlated with seizure frequency and stigma and negatively correlated with quality of life, social support and overall functioning. These results highlight the importance of routine screening for depression, and of providing management of these symptoms in comprehensive epilepsy care.

This study aimed to determine the prevalence of paternal perinatal depression (PPND) using the Edinburgh Postnatal Depression Scale (EPDS) among fathers/co-parents at an urban obstetric hospital and identify key predictors of positive screening outcomes.

A cross-sectional anonymous online survey was completed by 115 respondents between July 2023 and January 2024. The questionnaire included demographic and clinical items, the EPDS, and the Social Safety and Pleasure Scale (SSPS). An EPDS score ≥ 9 indicated a positive screen for depression. A composite variable for history of mental illness was created based on prior diagnosis, mental health service engagement, and medication use.

Thirty-three percent of participants screened positive for depression (EPDS ≥ 9); 17.4% had scores ≥ 12. A self-reported history of mental illness significantly predicted positive screening (OR = 4.38, p = 0.001). No significant associations were found with demographic, obstetric, or infant-related variables. Lower SSPS scores were significantly associated with higher EPDS scores.

Despite limitations, in particular selection bias and small sample size, fathers and co-parents are at increased risk for depressive symptoms in the perinatal period, particularly those with a mental health history. Routine screening and inclusive models of care are needed to support paternal mental health during this vulnerable time.

To determine the rate of healthcare personnel (HCP) glove or gown contamination with methicillin-resistant Staphylococcus aureus (MRSA) and to estimate which patient care interactions and HCP roles are associated with greater contamination.

Multicenter cohort study.

Five Veterans Affairs medical centers in the United States.

Patients with a positive MRSA clinical or surveillance culture within the past 7 days were enrolled. Five HCP in the room were observed for each patient. After completion of tasks and prior to room exit, HCP gloves and gowns were cultured separately.

We enrolled 799 patients and obtained 3,832 glove and gown cultures. Contamination of HCP gloves or gown with MRSA occurred 713 of 3,832 (18.6%) of the time, while 589 of 3,832 (15.4%) of interactions resulted in contamination of gloves, and 319 of 3,831 (8.3%) of interactions resulted in contamination of gowns. The gloves and gowns of physical therapists and occupational therapists were most frequently contaminated. Any interactions that involved touching the patient resulted in glove or gown contamination in 622 of 2,901 (21.4%) of observations, while touching only the environment resulted contamination in 91 of 931 (9.8%) of observations. Rates of glove or gown contamination were similar in the intensive care unit (ICU) and non-ICU.

Contamination of HCP gloves and gowns with MRSA occurs frequently when caring for Veteran patients particularly when there is direct patient contact. Hospitals may consider optimizing contact precautions by using fewer precautions for low-risk interactions and more precautions for high-risk interactions.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant genetic disorder leading to vascular malformations in different organ systems. Approximately 10% of patients with HHT have brain vascular malformations (BVMs). Due to the negative health consequences related to BVMs, screening with MRI is recommended. There are no health jurisdictional standards for medical imaging protocols in North America or elsewhere. The objective of this project is to adopt a provincial standardized operating protocol (SOP) to improve diagnostic accuracy and reduce inappropriate imaging in patients with and without HHT in Alberta.

Multiple fora were held among the five Alberta Health Services zones with stakeholders from urban, suburban and rural radiology groups, neurology, pulmonology and hematology. The consensus process took five years to complete between 2015 and 2020. The content of the fora was approved by all participants.

The SOP was implemented in February 2020 and defines that screening for BVMs must include standard unenhanced brain MRI (sagittal T1, axial fluid-attenuated inversion recovery and axial T2) with susceptibility-weighted imaging (SWI), a 3T or 1.5T magnet strength and minimum imaging standards to include 3 mm contiguous slice thickness.

Incorporation of SWI allowed for the elimination of MR contrast to improve access to the local performance of studies within the province, facilitating virtual care.

A provincial SOP for BVM screening in patients with suspected or confirmed HHT was successfully implemented in Alberta. Gadolinium was avoided, as it was felt to be unnecessary for screening purposes and might complicate imaging at more remote sites.

It remains unclear which individuals with subthreshold depression benefit most from psychological intervention, and what long-term effects this has on symptom deterioration, response and remission.

To synthesise psychological intervention benefits in adults with subthreshold depression up to 2 years, and explore participant-level effect-modifiers.

Randomised trials comparing psychological intervention with inactive control were identified via systematic search. Authors were contacted to obtain individual participant data (IPD), analysed using Bayesian one-stage meta-analysis. Treatment–covariate interactions were added to examine moderators. Hierarchical-additive models were used to explore treatment benefits conditional on baseline Patient Health Questionnaire 9 (PHQ-9) values.

IPD of 10 671 individuals (50 studies) could be included. We found significant effects on depressive symptom severity up to 12 months (standardised mean-difference [s.m.d.] = −0.48 to −0.27). Effects could not be ascertained up to 24 months (s.m.d. = −0.18). Similar findings emerged for 50% symptom reduction (relative risk = 1.27–2.79), reliable improvement (relative risk = 1.38–3.17), deterioration (relative risk = 0.67–0.54) and close-to-symptom-free status (relative risk = 1.41–2.80). Among participant-level moderators, only initial depression and anxiety severity were highly credible (P > 0.99). Predicted treatment benefits decreased with lower symptom severity but remained minimally important even for very mild symptoms (s.m.d. = −0.33 for PHQ-9 = 5).

Psychological intervention reduces the symptom burden in individuals with subthreshold depression up to 1 year, and protects against symptom deterioration. Benefits up to 2 years are less certain. We find strong support for intervention in subthreshold depression, particularly with PHQ-9 scores ≥ 10. For very mild symptoms, scalable treatments could be an attractive option.

There is wide variation in institutional sedation strategies in paediatric cardiac ICU. Validated tools such as State Behavioral Scale and Richmond Agitation Sedation Scale were created to help standardise sedation practices.

This is a multi-phase, multicentre, prospective project with the goal of optimising safety and comfort for paediatric cardiac ICU patients. Phase one consisted of an educational intervention with a self-paced, web-based video module on optimal sedation practices using validated sedation screening tools. Participant knowledge was assessed via a de-identified, unmatched pre- and post-test survey. Survey scores were reported as an aggregate average score and compared using a t-test.

There were 259 pre-tests, and 142 post-tests collected during the video-assisted educational intervention. There was a significant increase in mean score on the post-test compared to the pre-test for both instruments: from 4 to 4.8/10 for State Behavioral Scale (p = 0.01) and from 4.5 to 4.9 for Richmond Agitation Sedation Scale (p = 0.04). 81% of respondents who completed the Richmond Agitation Sedation Scale post-test and 88.1% of those who completed the State Behavioral Scale post-test said their practice would change based on the new knowledge acquired.

We report that our newly developed learning module intervention was effective in increasing short-term knowledge about optimal sedation and sedation scoring. Ongoing phase two efforts include evaluation of long-term compliance of validated sedation screening tools and developing an objective score to measure individual cumulative opioid dosing in the cardiac critical care unit.

To identify risk factors for methicillin-susceptible (MSSA) and methicillin-resistant S. aureus (MRSA) nasal carriage and surgical site infection (SSI) among patients undergoing fracture fixation procedures who were included in a quality improvement protocol involving screening patients for S. aureus nasal carriage and treating carriers with intranasal mupirocin and chlorhexidine bathing.

Retrospective cohort study.

Level 1 trauma center.

1,254 adults who underwent operative fixation of 1,298 extremity or pelvis fractures between 8/1/2014 – 7/31/2017.

We calculated rates of S. aureus nasal carriage and SSI. We used multivariable stepwise logistic regression and selected the final models based on Akaike information criterion.

Of the 1,040 screened first procedures, 262 (25.19%) were performed on S. aureus nasal carriers: 211 (20.29%) on MSSA carriers and 51 (4.90%) on MRSA carriers. Long-term care facility residence (odds ratio [OR] 3.38; 95% confidence interval [CI] 1.17–9.76) was associated with MRSA nasal carriage. After adjusting for statistically and clinically significant variables, MRSA carriage was significantly associated with any SSI (OR 4.58; 95% CI 1.63–12.88), S. aureus SSI (OR 10.11; 95% CI 3.25–31.42), and MRSA SSI (OR 27.25; 95% CI 5.33–139.24), whereas MSSA carriage was not. Among S. aureus carriers, any chlorhexidine use was documented for 232 (88.55%), and any intranasal mupirocin was documented for 85 (40.28%) MSSA carriers and 33 (64.71%) MRSA carriers.

MRSA carriage was associated with a significant risk of SSI after operative fracture fixation. Many carriers did not undergo decolonization, suggesting that a simplified decolonization protocol is needed.

Negative symptoms are a key feature of several psychiatric disorders. Difficulty identifying common neurobiological mechanisms that cut across diagnostic boundaries might result from equifinality (i.e., multiple mechanistic pathways to the same clinical profile), both within and across disorders. This study used a data-driven approach to identify unique subgroups of participants with distinct reward processing profiles to determine which profiles predicted negative symptoms.

Participants were a transdiagnostic sample of youth from a multisite study of psychosis risk, including 110 individuals at clinical high-risk for psychosis (CHR; meeting psychosis-risk syndrome criteria), 88 help-seeking participants who failed to meet CHR criteria and/or who presented with other psychiatric diagnoses, and a reference group of 66 healthy controls. Participants completed clinical interviews and behavioral tasks assessing four reward processing constructs indexed by the RDoC Positive Valence Systems: hedonic reactivity, reinforcement learning, value representation, and effort–cost computation.

k-means cluster analysis of clinical participants identified three subgroups with distinct reward processing profiles, primarily characterized by: a value representation deficit (54%), a generalized reward processing deficit (17%), and a hedonic reactivity deficit (29%). Clusters did not differ in rates of clinical group membership or psychiatric diagnoses. Elevated negative symptoms were only present in the generalized deficit cluster, which also displayed greater functional impairment and higher psychosis conversion probability scores.

Contrary to the equifinality hypothesis, results suggested one global reward processing deficit pathway to negative symptoms independent of diagnostic classification. Assessment of reward processing profiles may have utility for individualized clinical prediction and treatment.

Information on the time spent completing cognitive testing is often collected, but such data are not typically considered when quantifying cognition in large-scale community-based surveys. We sought to evaluate the added value of timing data over and above traditional cognitive scores for the measurement of cognition in older adults.

We used data from the Longitudinal Aging Study in India-Diagnostic Assessment of Dementia (LASI-DAD) study (N = 4,091), to assess the added value of timing data over and above traditional cognitive scores, using item-specific regression models for 36 cognitive test items. Models were adjusted for age, gender, interviewer, and item score.

Compared to Quintile 3 (median time), taking longer to complete specific items was associated (p < 0.05) with lower cognitive performance for 67% (Quintile 5) and 28% (Quintile 4) of items. Responding quickly (Quintile 1) was associated with higher cognitive performance for 25% of simpler items (e.g., orientation for year), but with lower cognitive functioning for 63% of items requiring higher-order processing (e.g., digit span test). Results were consistent in a range of different analyses adjusting for factors including education, hearing impairment, and language of administration and in models using splines rather than quintiles.

Response times from cognitive testing may contain important information on cognition not captured in traditional scoring. Incorporation of this information has the potential to improve existing estimates of cognitive functioning.
