Abstract PDF Supplementary Material: Background
Textile dyeing workers are at an increased risk of developing occupational respiratory diseases owing to frequent exposure to harmful chemicals, irritants, and high humidity in the workplace. Pulmonary rehabilitation is essential but associated with access and adherence challenges. This study aimed to evaluate the feasibility, effectiveness, accessibility, and safety of an app-based pulmonary telerehabilitation program for this population.
Methods
Forty-five textile dyeing workers with respiratory symptoms underwent a 4-week pulmonary telerehabilitation program consisting of daily gamified respiratory muscle training using a Bluetooth-enabled device and video-guided flexibility exercises. The program was delivered through a mobile application and adherence was monitored using an online platform. Pulmonary function tests, 6-minute walk test, hand grip strength, and St. George’s Respiratory Questionnaire (SGRQ) scores were assessed at baseline (T0) and post-intervention (T1). The adherence, adverse events, and system usability were evaluated.
Results
Improvements were observed in forced expiratory volume in 1 second (FEV1), FEV1/forced vital capacity, maximal inspiratory pressure, and maximal expiratory pressure at T1 compared to T0. The SGRQ activity scores improved after the intervention. The mean adherence rate was 95.69%; three participants had adherence rates <80% for ≥1 week each. The mean System Usability Scale score was high.
Conclusion
The program resulted in significant improvements in pulmonary function and quality of life with high adherence rates and good usability. This may be a promising approach for managing occupational respiratory diseases among textile dyeing workers. Further studies with larger sample sizes and longer follow-up periods are warranted to validate these results and assess the long-term outcomes.

Neurolymphomatosis (NL) is defined as the involvement of the peripheral nervous system in lymphocytic invasion. It is a very rare form of lymphoma that may occur as an initial presentation or recurrence. It affects various peripheral nervous structures and can therefore mimic disc-related nerve root pathology or compressive mononeuropathy. NL often occurs in malignant B-cell non-Hodgkin lymphomas. Notwithstanding its aggressiveness or intractability, NL should be discriminated from other neurologic complications of lymphoma. Herein, we present a case of primary NL as the initial presentation of diffuse large B-cell lymphoma (DLBCL) of the sciatic nerve. The patient presented with weakness and pain in his left leg but had no obvious lesion explaining the neurologic deficit on initial lumbosacral and knee magnetic resonance imaging (MRI). NL of the left sciatic nerve at the greater sciatic foramen was diagnosed based on subsequent hip MRI, electrodiagnostic test, positron emission tomography/computed tomography, and nerve biopsy findings. Leg weakness slightly improved after chemotherapy and radiotherapy. We report a case wherein NL, a rare cause of leg weakness, manifested as the initial presentation of primary DLBCL involving the sciatic nerve at the greater sciatic foramen.
