Objective:
The clinical presentation of depressive disorders might be influenced by age, and its diagnosis and treatment can be affected by ageism-related bias. A network analysis can reveal symptom patterns unrecognized by the reductionistic approach. Therefore, this study explores the network structure of depression and anxiety symptoms in older Asian patients with depressive disorders and examines age-related differences in the context of ageism.
Methods:
We used data from the Research on Asian Psychotropic Prescription Patterns for Antidepressants, Phase 3 study and included 2,785 psychiatric patients from 11 Asian countries. Depression and anxiety symptoms were assessed using the Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7. Network analyses were conducted to identify symptom interconnections and centrality among older (>65 years), middle-aged (35–64 years), and young (18–34 years) adult groups. The network structures were also compared using a network comparison test.
Results:
Depressed mood was the most central symptom across all age groups. Network comparisons revealed no significant structural differences among the three age groups, despite several variations in terms of global strength. The network structure of the older group was characterized by strong interconnections between somatic symptoms (insomnia-energy) and core depressive symptoms (little interest or pleasure-feelings of hopelessness).
Conclusion
This study reveals that the network structures of depression and anxiety symptoms have relatively consistent interconnections across age groups, despite subtle age-based differences. Specifically, older adults tend to present anxiety and depression symptoms as physical complaints. These findings challenge ageist stereotypes and advocate for inclusive, age-neutral approaches to treatment.

Objective:
To implement early rehabilitation interventions by physical therapists is recommended. However, the effectiveness of early rehabilitation for severe coronavirus disease 2019 (COVID-19) patients in the prevention of post-intensive care syndrome (PICS) is unclear. We analyzed a multicenter prospective observational study (Post-Intensive Care outcomeS in patients with COronaVIrus Disease 2019) to examine the association between early rehabilitation interventions and PICS physical impairment.
Methods:
An analysis was performed on COVID-19 patients who were admitted to intensive care units (ICUs) between March 2020 and March 2021, and required mechanical ventilation. The primary outcome was the incidence of PICS physical impairment (Barthel Index≤90) after one year. Multivariate logistic regression analysis was used to estimate the association between early rehabilitation interventions and PICS physical impairment by adjusting ICU mobility scale (IMS) during seven-day following ICU admission, and clinically relevant risk factors.
Results:
The analysis included 259 patients, 54 of whom developed PICS physical impairment one year later. In 81 patients, physical therapists intervened within seven days of ICU admission. There was no significant difference in mean IMS by day seven of admission between the early and non-early rehabilitation patients (0.70 and 0.61, respectively). Multivariate logistic regression analysis showed that early rehabilitation interventions were significantly associated with a low incidence of PICS physical impairment (odds ratio, 0.294; 95% confidence interval, 0.123–0.706; p=0.006).
Conclusion
Early rehabilitation interventions by physical therapists were an independent factor associated with the decreased development of PICS physical impairment at one year, even though early rehabilitation had no significant effect on IMS.

Objective: The initial and operational costs of telemedicine are major barriers to its adoption. We aimed to investigate and identify the barriers to adopting a telemedicine system in a Japanese rural general hospital without incurring setup and operational costs.Materials and Methods: Our study was conducted between May and August 2018, and included six general practitioners working at a rural general hospital. We extracted data collected from messages (date and time, sender and recipient, and counts and contents of messages) and conducted semi-structured interviews, which were then analyzed using quantitative and qualitative methods.Results: We quantitatively analyzed the total counted of the 179 messages. The total counts recorded for each physician were 56 (A), 20 (B), 3 (C), 74 (D), 5 (E), and 21 (F). The mean monthly counts were 2.17 (May), 8.50 (June), 11.50 (July), and 7.67 (August). Interview data from the six physicians yielded 13 codes that included various points of dissatisfaction acting as barriers to using our system, which we grouped into mental and physical barriers. Mental barriers included suspicion of carrying, feelings of isolation, and loss, whereas physical barriers included portability, user authentication, internet speed, group chat system, notice, search image, typing, chat system, print facility, and limited function.Conclusion: The representative barriers to introducing a telemedicine system at a rural general hospital in Japan without initial and running costs could be classified as feelings of isolation and suspicion of carrying (mental barriers); and notice, portability, and user authentication (physical barriers). Continued investigation in this area is warranted, and solutions to these barriers could improve the shortage of medical staff in the context of declining birth rates and aging populations in Japan.

Objective:
The purposes of this trial were to demonstrate the feasibility and effectiveness of the hybrid of intracavitary and interstitial brachytherapy (HBT) for locally advanced cervical cancer patients in the phase I/II prospective clinical trial.
Methods:
Patients with FIGO stage IB2-IVA uterine cervical cancer pretreatment width of which was ≥5 cm measured by magnetic resonance imaging were eligible for this clinical trial. The protocol therapy included 30–30.6 Gy in 15–17 fractions of whole pelvic radiotherapy concurrent with weekly CDDP, followed by 24 Gy in 4 fractions of HBT and pelvic radiotherapy with a central shield up to 50–50.4 Gy in 25–28 fractions. The primary endpoint of phase II part was 2-year pelvic progression-free survival (PPFS) rate higher than historical control of 64%.
Results:
Between October 2015 and October 2019, 73 patients were enrolled in the initial registration and 52 patients proceeded to the secondary registration. With the median follow-up period of 37.3 months (range, 13.9–52.9 months), the 2- PPFS was 80.7% (90% confidence interval [CI]=69.7%–88%). Because the lower range of 90% CI of 2-year PPFS was 69.7%, which was higher than the historical control ICBT data of 64%, therefore, the primary endpoint of this study was met.
Conclusion
The effectiveness of HBT were demonstrated by a prospective clinical study. Because the dose goal determined in the protocol was lower than 85 Gy, there is room in improvement for local control. A higher dose might have been needed for tumors with poor responses.
