Caring Contacts to Reduce Psychiatric Morbidity Following Hospitalization During the COVID-19 Pandemic: A Pilot Randomized Controlled Trial.

OBJECTIVES: Caring Contacts are an emerging intervention that aims to reduce distress and suicide risk after acute psychiatric care. This trial aimed to determine whether, during a pandemic, there was any evidence that the mental health benefits and reduction in suicidal ideation (SI) associated with delivering Caring Contacts to recently discharged psychiatric patients were greater than a control communication. The secondary objective was to identify whether the predicted benefits were greater among people living alone or those diagnosed with depression. METHOD: A single-site pilot randomized clinical trial (n = 100), with patients recruited from the adult Inpatient Psychiatry Unit at Sunnybrook Health Sciences Centre, Toronto, Canada between August 2020 and May 2021. Participants were randomized (1:1) to the Caring Contact or control group. Participants received three Caring Contact or control communications via email or mail (on days 4, 21, and 56 post-discharge). Mental health symptoms were assessed using the self-report Hopkins Symptom Checklist-25 (HSCL-25) scores at discharge (baseline) and when participants received each communication. Analysis of variance was used for the primary comparisons and exploratory analyses for subgroups. RESULTS: Both groups experienced a significant worsening of mental health symptoms at all time points post-discharge relative to baseline. There were no significant differences between groups at any time point, however, on day 4 there was a 24.2% and 72.6% attenuated worsening in the Caring Contact group compared to the control group for total symptom severity and SI, respectively. There was no significant interaction effect for the depression subgroup or those living alone. CONCLUSIONS: While this pilot study was not powered to identify significant differences between groups, results are indicative of feasibility and acceptability of the intervention and provide some indication that Caring Contacts may have benefited patients in the days following discharge, supporting the need for larger-scale trials. The study was registered with clinicaltrials.gov (study ID NCT04456062).

Exploring the Effects of Using an Oral Appliance to Reduce Movement Dysfunction in an Individual With Parkinson Disease: A Single-Subject Design Study.

BACKGROUND AND PURPOSE: Clinical reports suggest that wearing an oral appliance can improve the gait and balance of an individual with Parkinson disease (PD). Our primary purpose was to systematically explore this effect using a single-subject study design and quantitative motion analysis. Secondarily, we sought to examine the quality-of-life outcomes following 1-month of routine oral appliance wear. METHODS: The participant was a 73-year-old ambulatory man with mid-stage PD. Using an A-B-A design, for which a custom-made oral appliance served as the intervention, kinematic and kinetic data were captured during performance of Four Square Step Test, serpentine walk, and tandem walk tasks. Grip strength was quantified with a dynamometer. Quality-of-life outcomes were collected after 1 month of appliance wear using the Parkinson Disease Questionnaire-39 (PDQ-39). Perceived changes in balance, mobility, and quality of life were captured from the participant using an 11-point Global Rate of Change (GRC) scale. RESULTS: Changes in mobility, postural control, and grip strength during appliance wear were suggestive of reduced movement dysfunction. The PDQ-39 revealed a significant improvement in quality of life, primarily related to increased emotional well-being, decreased stigma, and increased communication. GRC scores indicated a clinically significant improvement in ease of movement in the community (+3), ease of movement during the performance of activities of daily living (+4), and in standing balance while performing activities of daily living (+4). DISCUSSION AND CONCLUSIONS: Study findings provided quantitative evidence supporting the effectiveness of oral appliance wear for reducing movement dysfunction in a patient with mid-stage PD.Video Abstract available for more insights from the authors (see Supplemental Digital Content 1, http://links.lww.com/JNPT/A155).

Long-term burden of care and radiation exposure in survivors of esophageal atresia.

BACKGROUND: Patients with esophageal atresia with or without tracheoesophageal fistula (EA/TEF) historically have had a high risk of neonatal mortality but the majority of patients are now expected to live into adulthood. However, the long-term burden of care among recent EA/TEF survivors has not been documented. METHODS: A single-institution retrospective review of newborns with EA/TEF treated from 2001-2005 was conducted, including initial and total hospitalization length of stay, and number of clinic visits and procedures requiring general anesthesia in the first three years of life. Exposure to and number of radiological studies involving ionizing radiation (IR) were recorded. RESULTS: Seventy-one of 78 (91%) patients survived to discharge and 69 were included for analysis. Mean length of initial hospital stay was 51.3 (range 9-390) days. By age 3 years, patients required 4.5 (mean, range 1-23) procedures performed under general anesthesia, attended 13.5 (mean, range 3-40) outpatient visits and were exposed to 17.4 mSv (mean, range 3.0-59.9) of IR from 40 (mean, range 5-165) radiological studies. CONCLUSION: Patients with EA/TEF need complex and frequent hospital-based care from infancy to early childhood. Opportunities to critically review clinical services and imaging needs should be explored to improve the experience of patients and their families.

Shell hardness and compressive strength of the Eastern oyster, Crassostrea virginica, and the Asian oyster, Crassostrea ariakensis.

The valves of oysters act as a physical barrier between tissues and the external environment, thereby protecting the oyster from environmental stress and predation. To better understand differences in shell properties and predation susceptibilities of two physiologically and morphologically similar oysters, Crassostrea virginica and Crassostrea ariakensis, we quantified and compared two mechanical properties of shells: hardness (resistance to irreversible deformation; GPa) and compressive strength (force necessary to produce a crack; N). We found no differences in the hardness values between foliated layers (innermost and outermost foliated layers), age class (C. virginica: 1, 4, 6, 9 years; C. ariakensis: 4, 6 years), or species. This suggests that the foliated layers have similar properties and are likely composed of the same material. The compressive force required to break wet and dry shells was also not different. However, the shells of both six- and nine-year-old C. virginica withstood higher compressive force than C. virginica shells aged either one or four, and the shells of C. ariakensis at both ages studied (4- and 6-years-old). Differences in ability to withstand compressive force are likely explained by differences in thickness and density between age classes and species. Further, we compared the compressive strength of differing ages of these two species to the crushing force of common oyster predators in the Chesapeake Bay. By studying the physical properties of shells, this work may contribute to a better understanding of the mechanical defenses of oysters as well as of their predation vulnerabilities.
