ABSTRACT

Objective

The COVID-19 pandemic prompted the widespread adoption of telemedicine as an alternative to in-person care. This systematic scoping review evaluated the effectiveness, cost-efficiency, and challenges of telemedicine for patients with rheumatic diseases.

Methods

A comprehensive search of the MEDLINE database was conducted using specific terms related to rheumatoid or juvenile arthritis, and telemedicine. The literature search included studies published up to March, 2024. In this review, we only considered studies assessing telemedicine as an alternative to in-person care.

Results

The search, conducted on 15 March 2024, generated 258 references. Eight reports from three randomized controlled trials and three observational studies were included. Randomized controlled trials have shown that the outcomes of telemedicine intervention are comparable to those of in-person care in terms of disease activity, functional status, and quality of life, while enabling fewer outpatient visits and cost-effectiveness. However, the high dropout rates highlight the importance of patient preferences and comprehensive education. Observational studies revealed similar findings but were limited by a high confounding bias.

Conclusion

Telemedicine offers economic advantages and maintains clinical outcomes comparable to those of in-person care. Its success depends on structured patient education and alignment with patient preferences. Further research is required, particularly in the context of healthcare in Japan.

We investigated the roles of low-density lipoprotein receptor-related protein (LRP) 4 and its ligand Agrin in the pathophysiology of cartilage degeneration. Immunohistochemical analysis of human normal articular cartilage and cartilage tissues from patients with osteoarthritis (OA) obtained during surgery of the knee joint showed marked LRP4 expression in the early stages of OA, which then decreased with cartilage degeneration, whereas Agrin was consistently increased with cartilage degeneration. In normal human articular chondrocytes (NHACs), mild cyclic tensile strain (CTS) (0.5 Hz, 5% elongation, 2 h) increased the expression of LRP4 and aggrecan (ACAN), while intense CTS (0.5 Hz, 10% elongation, 6 h) increased the expression of Agrin without affecting LRP4 expression. Treatment with recombinant human (rh) Agrin downregulated the mRNA expression of LRP4 and ACAN, but upregulated the expression of LRP5/6, SRY-box transcription factor 9 (SOX9), Runt-related transcription factor 2 (RUNX2), and a disintegrin and metalloproteinase with thrombospondin motifs-4 (ADAMTS-4). Immunocytochemistry and Western blot analysis showed that rhAgrin treatment upregulated the expression of β-catenin and SOX9. Agrin knockdown by siAGRN transfection partially reduced the nuclear protein expression of β-catenin, which was increased with intense CTS. LRP4 knockdown by siLRP4 transfection increased the expression of LRP5/6, SOX9, RUNX2, ADAMTS-4, and Agrin. These results suggested that intense CTS increases the expression of Agrin, which might interfere with the role of LRP4 in the inhibition of LRP5/6 and their downstream β-catenin signaling, leading to cartilage degeneration.

ABSTRACT

Objective

To investigate the effect of the use of biologic disease-modifying antirheumatic drugs (bDMARDs) on surgical site infection (SSI) and delayed wound healing (DWH) in rheumatoid arthritis (RA) patients undergoing orthopaedic surgery.

Methods

We retrospectively reviewed the records of 965 elective orthopaedic procedures undertaken in RA patients. The incidences of SSI and DWH were compared between the bDMARDs user and nonuser groups. Subsequently, univariate and multivariate logistic regression analyses were performed to evaluate risk factors for SSI and DWH after propensity score matching. The incidence of postoperative flare-up was also examined.

Results

In 965 procedures, SSI and DWH were identified in 12 and 28 cases, respectively. SSI and DWH were identified in 3 and 17 of 414 procedures treated with bDMARDs, respectively. Flare-up occurred in 21 cases. Propensity score matching identified 315 cases in both groups, with no significant difference in incidence between the two groups. No risk factors for SSI were identified, whereas age, diabetes mellitus, foot and ankle surgery, and a history of musculoskeletal-related infection were identified as risk factors for DWH.

Conclusion

The use of bDMARDs was not associated with an increased incidence of SSI or DWH, with the incidence of flare-up being relatively low.

Insomnia can coexist with chronic pain and is a major cause of rapidly increasing medical expenses. However, insomnia has not been fully evaluated in patients with chronic pain. This retrospective study aimed to identify the risk factors for insomnia in patients with chronic non-cancer pain. A total of 301 patients with chronic non-cancer pain were enrolled. Patients with the Athens insomnia scale scores ≥ 6 and < 6 were classified into insomnia (+) and insomnia (−) groups, respectively. All patients completed self-report questionnaires as part of their chronic pain treatment approach. Univariate and multivariate analyses were performed to predict insomnia. We found that 219 of 301 (72.8%) patients met the AIS criteria for insomnia. Significant differences were depicted between patients with and without insomnia in terms of body mass index, numeric rating scale, pain catastrophizing scale, hospital anxiety, and depression scale (HADS), pain disability assessment scale, EuroQol 5 dimension (EQ5D), and pain self-efficacy questionnaire. Multiple regression analysis identified the numeric rating scale, HADS, and EQ5D scores as factors related to insomnia in patients with chronic non-cancer pain. Anxiety, depression, and disability were associated with a greater tendency toward insomnia. HADS and EQ5D scores are useful screening tools for preventing insomnia in patients with chronic non-cancer pain.

BACKGROUND: The purpose of this study was to examine two techniques for Carpal Tunnel Syndrome, mini-Open Carpal Tunnel Release (mini-OCTR) and Endoscopic Carpal Tunnel Release (ECTR), to compare their therapeutic efficacy. METHODS: Sixteen patients who underwent mini-OCTR in palmar incision and 17 patients who underwent ECTR in the wrist crease incision were included in the study. All patients presented preoperatively and at 1, 3, and 6 months postoperatively and were assessed with the Visual Analogue Scale (VAS) and the Disabilities of Arm, Shoulder and Hand Score (DASH). We also assessed the pain and cosmetic VAS of the entire affected hand or surgical wound, and the patient's satisfaction with the surgery. RESULTS: In the objective evaluation, both surgical techniques showed improvement at 6 months postoperatively. The DASH score was significantly lower in the ECTR group (average = 3 months: 13.6, 6 months: 11.9) than in the mini-OCTR group (average = 3 months: 27.3, 6 months: 20.6) at 3 and 6 months postoperatively. Also, the pain VAS score was significantly lower in the ECTR group (average = 17.1) than in the mini-OCTR group (average = 36.6) at 3 months postoperatively. The cosmetic VAS was significantly lower in the ECTR group (average = 1 month: 15.3, 3 months: 12.2, 6 months: 5.41) than in the mini-OCTR group (average = 1 month: 33.3, 3 months: 31.2, 6 months: 24.8) at all time points postoperatively. Patient satisfaction scores tended to be higher in the ECTR group (average = 3.3) compared to the mini-OCTR group (average = 2.7). CONCLUSIONS: ECTR in wrist increase incision resulted in better pain and cosmetic recovery in an early postoperative phase compared with mini-OCTR in palmar incision. Our findings suggest that ECTR is an effective technique for patient satisfaction.
