Purpose: This systematic review aims to assess and summarize the clinical values of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) parameter changes as early biomarkers of tumor responses following radiation therapy (RT) in patients with spinal metastases. Materials and Methods: A systematic search was conducted on five electronic databases: PubMed, Scopus, Science Direct, Cochrane, and Embase. Studies were included if they mentioned DCE-MRI parameter changes before and after RT in patients with spinal metastases with a correlation to tumor responses based on clinical and imaging criteria. The Quality Assessment of Diagnostic Accuracy Studies 2 was used to assess study quality. Results: This systematic review included seven studies involving 107 patients. All seven studies evaluated the transfer constant (Ktrans), six studies evaluated the plasma volume fraction (Vp), three studies evaluated the extravascular extracellular space volume fraction, and two studies evaluated the rate constant. There were variations in the type of primary cancer, RT techniques used, post-treatment scan time, and median follow-up time. Despite the variations, however, the collected evidence generally suggested that significant differences could be detected in DCE-MRI parameters between before and after RT, which might reflect treatment success or failures in long-term follow-up. Responders showed higher reduction and lower values of Ktrans and Vp after RT. DCE-MRI parameters showed changes and detectable recurrences significantly earlier (up to 6 months) than conventional MRI with favorable diagnostic values. Conclusion The results of this systematic review suggested that DCE-MRI parameter changes in patients with spinal metastases could be a promising tool for treatment-response assessment following RT. Lower values and higher reduction of Ktrans and Vp after treatment demonstrated good prediction of local control. Compared to conventional MRI, DCE-MRI showed more rapid changes and earlier prediction of treatment failure.

Purpose: The practice of feedback is influenced by the characteristics of students, teachers, and the clinical environment. Most studies on feedback have been conducted in Western settings with different sociocultural backgrounds to Indonesia. This study explores feedback in Indonesian clinical clerkship using a sociocultural lens and aims to provide an exemplar of adaptive practice relevant to non-Western settings. Methods: This qualitative study was conducted using an interpretive phenomenology approach. Data were collected through focus groups with students and teachers and interviews with program coordinators. Data were transcribed verbatim and grouped according to data sources, coded, and analyzed thematically. Results: Themes identified from the focus group discussions and interviews were categorized as student, teacher, and environmental factors. Student factors include dependence on feedback, tendencies to use a group approach, difficulties recognizing social rules, a perceived lack of resilience, and tendencies to doubt praise. Factors related to teachers include a high level of expertise, being extremely busy, having a strong commitment, and being unsure of students’ acceptance of feedback. Clinical environment factors influence interactions between teachers and learners and include high power distance and collectivistic values. A safe environment is needed to ensure effective feedback interactions. Conclusion High power distance, collectivism, and generational characteristics of students likely impact feedback practice in clinical settings. Designing a safe environment is essential for effective feedback practice.

Background and Objectives: Post-extubation dysphagia (PED) is a condition characterized by swallowing difficulty following the removal of breathing tube. Untreated dysphagia leads to increased morbidity and mortality; however, no study has been conducted on the proportion of PED at RSUPN Dr. Cipto Mangunkusumo (RSCM), using flexible endoscopic evaluation of swallowing (FEES), or on the factors that contribute to its occurrence.Subjects and Method Anamnesis and medical record review were conducted on post-extubation patients in the RSCM intensive care unit (ICU) meeting inclusion criteria. Research subjects underwent maximum phonation time (MPT) examination thrice. FEES examination was carried out twice, with 24 hours of post-extubation on all subjects and 72 hours of postextubation on those with PED on initial FEES examination. Results: The study involved 33 subjects who met the inclusion criteria. The proportion of mild to severe PED determined by FEES 24 hours after extubation was 66.7%, and those exhibiting laryngeal injury was 87.9%. The bivariate analysis revealed a significant correlation between the number of comorbidities, intubation duration, laryngeal injury severity, and MPT value with the incidence of PED in the RSCM ICU. Moreover, the multivariate analysis showed that the duration of intubation exceeding 24 hours had a statistically significant association with the incidence of PED (p=0.003; OR 15.30; 95% CI 2.46-95.19). Conclusion The proportion of mild to severe dysphagia in post-extubation patients in the RSCM ICU is quite high. Intubation duration exceeding 24 hours and having more than one comorbidity significantly contribute to the increased risk of dysphagia in post-extubated patients in the RSCM ICU.

Objective: Stress urinary incontinence (SUI) is a common problem that affects the quality of life of women worldwide. Pelvic floor muscle training (PFMT) is an effective conservative first-line treatment for SUI. However, low compliance with PFMT is one of the main reasons for therapeutic failure. Indirect supervision using a guidebook may improve PFMT outcomes. To develop a PFMT guidebook using the analyze, design, development, implementation, and evaluation (ADDIE) method. Methods: A guidebook was developed from July 2020 to April 2021 using the ADDIE method. This prospective study used mixed methods, namely qualitative analysis, focus group discussions, and in-depth interviews, and involved various experts from urogynecology, urology, medical rehabilitation, and physiotherapy departments. A pilot study was conducted on patients with SUI to evaluate the effectiveness of the guidebook. Results: The ADDIE method was successfully implemented to develop the PFMT guidebook. The formative evaluation of the ADDIE steps mainly focused on the PFMT technique, content clarity, illustration, design, and color choice of the book. After the pilot study, the guidebook significantly improved Incontinence Impact Questionnaire, Short Form, 1-hour pad test, and perineometer scores. However, the pilot study showed no significant improvement in Urogenital Distress Inventory, Short Form scores. Conclusion The PFMT guidebook developed using the ADDIE method improved outcomes in patients with SUI.

Background and Objective: Premature ventricular complex (PVC) burden exhibits one of three circadian types, classified as fast-type, slow-type, and independent-type PVC. It is unknown whether PVC circadian types have different heart rate variability (HRV) parameter values. Therefore, this study aimed to evaluate differences in HRV circadian rhythm among fast-, slow-, and independent-type PVC. Methods: This cross-sectional observational study consecutively recruited 65 idiopathic PVC subjects (23 fast-, 20 slow-, and 22 independent-type) as well as five control subjects. Each subject underwent a 24-hour Holter to examine PVC burden and HRV. HRV analysis included components that primarily reflect global, parasympathetic, and sympathetic activities. Repeated measures analysis of variance was used to compare differences in HRV circadian rhythm by PVC type. Results. The average PVC burden was 15.7%, 8.4%, and 13.6% in fast-, slow-, and independent-type idiopathic PVC subjects, respectively. Global, parasympathetic nervous system, and sympathetic nervous system HRV parameters were significantly lower in independenttype PVC versus fast- and slow-type PVC throughout the day and night. Furthermore, we unexpectedly found that tendency towards sympathetic activity dominance during nighttime was only in independent-type PVC. Conclusion The HRV parameters are reduced in patients with independent-type PVC compared to fast- and slowtype PVC. Future research is warranted to determine possible differences in the prognosis between the three PVC types.
