Validating interRAI Chinese self-reported carer needs (SCaN) assessment and predicting caregiving distress among informal Chinese caregivers of older adults.

BACKGROUND: This study aims to (1) determine the reliability and validity of the interRAI Chinese Self-reported Carer Needs (SCaN) assessment among informal Chinese caregivers of older adults, (2) identify predictors of caregiving distress in Asian regions with long-standing Confucian values of filial piety and family responsibility. METHODS: This cross-sectional study recruited 531 informal Chinese caregivers of older adults in Hong Kong, Shanghai, Taiwan, and Singapore. The scale reliability was examined using Cronbach's alphas (α) and McDonald's omega coefficient (ω). The concurrent validity and discriminant validity were assessed using Spearman rank correlations (rho). To examine the predictors of caregiving distress among informal caregivers of older adults, we employed hierarchical linear regression analyses informed by the Model of Carer Stress and Burden and categorized the predictors into six domains. RESULTS: Results revealed good internal consistency reliability (α = 0.83-0.96) and concurrent validity (rho = 0.45-0.74) of the interRAI Chinese SCaN assessment. Hierarchical linear regression analysis revealed that entering the background factors, primary stressors, secondary stressors, appraisal, and exacerbating factors all significantly enhanced the model's predictability, indicating that the source of caregiving distress is multidimensional. In the full model, caregivers with longer informal care time, lack of support from family and friends, have unmet needs, experience role overload, have sleep problems, and low IADL functioning are at a higher risk of caregiving distress. CONCLUSIONS: The interRAI Chinese SCaN Assessment was found to be a reliable and valid tool among the Chinese informal caregivers of older adults. It would be useful for determining family caregivers' strengths, needs, and challenges, and tailoring interventions that address the potentially modifiable factors associated with caregiving distress and maximize support. Healthcare providers working in home and community settings should be aware of the early identification of caregiving distress and routine assessment of their needs and empower them to continue taking care of their needs and providing adequate care to the care recipient.

Sleep quality among undergraduate occupational therapy students in the University of Santo Tomas during the COVID-19 Pandemic: A descriptive cross-sectional study

Background@#Sleep is an essential occupation for students. It affects one's neurocognitive functions and psychomotor performance, playing a significant role in academic performance, health, and well-being. This study aims to describe the sleep quality and sleep patterns among undergraduate occupational therapy (OT) students at the University of Santo Tomas (UST) during the COVID-19 pandemic.@*Methods@#This descriptive cross-sectional study utilized a record review based on existing data from the UST OT Department's Student Life Survey 2021 database. A total of 205 students from different year levels and academic cohorts of the academic year 2021-2022 participated in the survey, which included the Pittsburgh Sleep Quality Index (PSQI). The data with valid responses (n=204) was analyzed using the measures of central tendency and dispersion, such as mean and standard deviation.@*Results@#Data analysis revealed that 95.59% (n=195) of student respondents had significantly poor sleep quality, while 4.41% (n=9) had good sleep quality. Students in the fifth-year level had the greatest sleep dysfunction as opposed to those in the third-year level who had little sleep dysfunction. Sleep duration and daytime dysfunction received the highest individual scores across all year levels.@*Conclusion@#Having poor sleep quality is a common occurrence among undergraduate OT students in UST during the COVID-19 pandemic. Sleep pattern trends suggest the need for school administrators and educators to create measures to mitigate possible negative effects on their student’s academic performance, health, and overall quality of life, especially during public health emergencies, calamities, and disasters.

Effect of performing real time three-dimensional transesophageal echocardiography in addition to two-dimensional transesophageal echocardiography on operator diagnostic confidence.

BACKGROUND: This study evaluates the effects of performing real time three-dimensional transesophageal echocardiography in addition to conventional two-dimensional transesophageal echocardiography on diagnostic confidence. METHODS: Operator diagnostic confidence in addressing clinical questions posed by the referral was scored using a five-point scale for two-dimensional transesophageal echocardiography alone and the combination of two-dimensional and real time three-dimensional transesophageal echocardiography in 136 consecutive patients undergoing examination in an academic hospital. RESULTS: Mean diagnostic confidence score was higher for the combined studies compared to two-dimensional transesophageal echocardiography alone (4.5 vs. 4.1, P < 0.001)). The addition of real time three-dimensional transesophageal echocardiography increased diagnostic confidence score in 45 (33.1%) patients, and the percentage of studies with total diagnostic confidence rose from 40.4% with two-dimensional transesophageal echocardiography alone to 65.4% after performing real time three-dimensional transesophageal echocardiography. Type of clinical indication was associated with improved score by the combined exams (P < 0.004). The addition of real time three-dimensional transesophageal echocardiography was most likely to improve diagnostic confidence score in studies performed to assess valve disease (56.1%) and least likely in examinations performed for intracardiac infection (14.9%). The location (anterior or posterior) of the primary cardiac pathology was not associated with improved score by the combined studies (P = 0.498). CONCLUSIONS: The addition of real time three-dimensional transesophageal echocardiography to two-dimensional transesophageal echocardiography increases diagnostic confidence in examinations routinely performed in an academic practice. Further studies of the impact of real time three-dimensional transesophageal echocardiography on patient management, outcomes and displacement of or need for downstream testing are warranted.

Coronary sinus electrode does not reduce atrial defibrillation thresholds.

BACKGROUND: Atrial defibrillation can be achieved with a conventional dual-coil, active pectoral implantable cardioverter-defibrillator (ICD) lead system. Shocking vectors that incorporate an additional electrode in the CS have been used, but it is unclear if they improve atrial DFTs. OBJECTIVE: The objective of this prospective, randomized study was to determine if a coronary sinus (CS) electrode reduces atrial defibrillation thresholds (DFTs). METHODS: This was a prospective study of 36 patients undergoing initial ICD implant for standard indications. A defibrillation lead with superior vena cava (SVC) and right ventricular (RV) shocking coils was implanted in the RV. An active can emulator (Can) was placed in a pre-pectoral pocket. A lead with a 4 cm long shocking coil was placed in the CS. Atrial DFTs were determined in the following 3 shocking configurations in each patient, with the order of testing randomized: RV --> SVC + Can (Ventricular Triad), distal CS --> SVC + Can (Distal Atrial Triad), and proximal CS --> SVC + Can (Proximal Atrial Triad). RESULTS: The Proximal and Distal Atrial Triad configurations were both associated with significant reductions in peak current (p < 0.01), but this effect was offset by significant increases in shock impedance (p < 0.01), resulting in no net change in the peak voltage or DFT energy in comparison to the Ventricular Triad configuration (Ventricular Triad: 4.9 +/- 6.6 J, Proximal Atrial Triad: 3.3 +/- 4.1J, Distal Atrial Triad: 4.4 +/- 6.7 J, p > 0.2). CONCLUSION: Shocking vectors that incorporate a CS coil do not significantly improve atrial defibrillation efficacy. Since the Ventricular Triad shocking pathway provides reliable atrial and ventricular defibrillation, this configuration should be preferred for combined atrial and ventricular ICDs.
