Development and Comprehensive Summative Evaluation of An Evidence-Based Caretaker's Handbook For Home-Based Physiotherapy And Activities Of Daily Living In Geriatric Neurological Patients

Aisiri P Kottur — 2026-04-04

Background: Diabetic neuropathy (DN) is a prevalent complication of diabetes mellitus leading to significant sensory and motor deficits. Conventional treatment focuses primarily on symptom control and glycemic regulation, offering limited neuromuscular function restoration. Low-intensity blood flow restriction training (LIBFRT) has emerged as a rehabilitation strategy that combines low-load resistance exercise with vascular occlusion to stimulate muscle adaptation at reduced mechanical stress, potentially suitable for DN patients.

Objective: This review aims to systematically synthesize existing evidence concerning the efficacy and safety of LIBFRT in DN management, evaluating intervention parameters, diagnostic criteria, clinical outcomes, and adverse events.

Methods: A comprehensive literature search identified 12 interventional studies (2010–2025) involving patients with clinically and neuro physiologically confirmed DN undergoing LIBFRT.Data extracted included occlusion pressures, exercise intensity, frequency, duration, outcome measures (muscle strength, neuropathic symptoms, nerve conduction, functional performance), and safety profiles.

Results: Protocols typically employed 20–40% 1-RM with individualized limb occlusion pressures (40–60% arterial occlusion) conducted 2–3sessions weekly for 4–8weeks. Across studies, LIBFRT improved muscle strength and mass, reduced neuropathic pain, stabilized/improved nerve conduction velocities, and enhanced functional mobility and balance. Safety data revealed no significant adverse vascular or neuropathic events.

Conclusion: LIBFRT appears to be a safe and effective adjunct in DN rehabilitation, promoting neuromuscular recovery and symptom alleviation. It merits incorporation into multidisciplinary care, but further large-scale RCTs with longer follow-up are warranted to refine protocols and confirm sustained benefits. Background: Parkinson disease and stroke among elderly patients pose high needs due to the need of home-based rehabilitation. The family caregivers offer most of the care but do not have the comprehensive and evidence based resources. The research findings show that trained caregivers enhance patient outcomes by 2040 percent[1][2][3] and lower healthcare expenses by 27-40 percent[1]. This is a project that will synthesize all the research evidence into a convenient handbook to assist the caretakers.

Purpose: To prepare a draft and summative assessment of a comprehensive and evidence-based handbook to support family members in the recovery of their stroke or ADL-assisted geriatric patients with stroke or Parkinson disease.

Methods: PubMed, Cochrane, EMBASE, PEDro, CINAHL were searched using systematic literature review (1999-2025) to select 30 high quality studies (12 systematic review/meta-analysis, 8 RCT, 10 observational/validation). Evidence summarized into 7-section handbook based on Functional Independence Measure (FIM) level[29]. Clinician/educator review of 8 experts. Pilot testing on 15 caregivers.

Findings Final handbook will include 124 pages and 48,000+ words. Seven key overall sections with detailed contents in all the areas of rehabilitation. Expert panel ratings (5-point Likert): Content Accuracy 4.6/5.0, Clarity 4.5/5.0, Clinical Utility 4.7/5.0, Safety Emphasis 4.8/5.0. Pilot implementation: the confidence of caregivers rose dramatically (3.2 to 7.8/10)[6], safety incidents reduced 75 percent[5], patient functional outcomes enhanced[2]. A high level of satisfaction and a high rate of recommendation was reported among all caregivers.

Conclusions: This clinical handbook fills important gaps in resources in home rehabilitation. FIM-level organization, condition-specific adaptations, safety protocols, and useful templates help caregivers to provide effective, safe, and scalable home-based rehabilitation. Extensive distribution via medical institutions, schools and online highly encouraged[23].

Chimeric Antigen Receptor (CAR)-T cell Therapy in Hematological Malignancies: Current Advances, Challenges, And Future Perspectives

Thota Lakshmi — 2026-04-16

Chimeric antigen receptor T-cell (CAR-T) therapy represents a groundbreaking advancement in cancer immunotherapy and has significantly transformed the treatment landscape for hematological malignancies. This innovative adoptive cellular therapy involves the genetic engineering of a patient’s T lymphocytes to express synthetic receptors capable of recognizing specific tumor-associated antigens on malignant cells. By enabling T cells to directly identify and eliminate cancer cells in a major histocompatibility complex-independent manner, CAR-T therapy has emerged as a highly effective therapeutic strategy for patients with relapsed or refractory hematologic cancers. In recent years, CAR-T therapies targeting antigens such as CD19 and B-cell maturation antigen (BCMA) have demonstrated remarkable clinical efficacy in diseases including acute lymphoblastic leukemia, diffuse large B-cell lymphoma, and multiple myeloma. Several CAR-T cell products have received regulatory approval and have shown high overall response rates and durable remissions in heavily pretreated patients who previously had limited treatment options.

Despite these encouraging outcomes, CAR-T therapy is associated with several limitations and safety concerns, including cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome, antigen escape, complex manufacturing procedures, and high treatment costs. Ongoing research efforts are focused on improving CAR design, enhancing T-cell persistence, identifying novel tumor targets, and developing universal or allogeneic CAR-T cell platforms. Additionally, emerging strategies such as dual-target CAR-T cells, gene-editing technologies, and combination therapies with immune checkpoint inhibitors are being investigated to further improve therapeutic efficacy and reduce adverse effects. This review provides a comprehensive overview of CAR-T cell therapy, including its mechanism of action, structural design, clinical applications in hematological malignancies, approved CAR-T therapies, treatment-related toxicities, current challenges, and future perspectives in the evolving field of cancer immunotherapy.
