Purpose: Our aim was to study the efficacy of combined triple therapy with intravitreal bevacizumab injections (IVB), posterior sub-Tenon injection of triamcinolone acetonide (STTA), and reduced laser fluence photodynamic therapy (RFPDT) in Japanese patients with retinal angiomatous proliferation (RAP).
Design: This was a retrospective, observational, consecutive case series.
Methods: Fifteen consecutive RAP treatment-naïve eyes were treated with triple therapy of IVB, STTA, and RFPDT (25 J/cm(2) of laser fluence). Whenever there was a recurrence of retinal-retinal anastomosis (RRA) or retinal-choroidal anastomosis (RCA) and marked leakage from subretinal neovascularization, the triple therapy was reapplied. When there were only intraretinal exudative and/or hemorrhagic changes without distinct RRA or RCA, IVB alone was applied.
Results: The mean logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) at baseline improved significantly (from 0.489 to 0.294 12 months) (paired t test, p = 0.043). LogMAR BCVA at 12 months was stable or improved by ≥ 0.2 in 14 eyes (93.3 %). Mean number of triple therapy instituted during the 12-month study period was 1.2, and mean number of IVB treatments was 1.4.
Conclusion: Combined IVB, STTA, and RFPDT for RAP was effective in maintaining or improving VA at 1 year. In addition, the number of treatments could be markedly reduced.

Breast cancer is the deadliest cancer among women and its treatment using traditional methods leads the patient to experience adverse effects. However, photodynamic therapy (PDT) is a non-invasive therapy modality that works through a photosensitizing agent, which treating activated by a suitable light source, releases reactive oxygen species capable of treating cancer. Furthermore, recent research indicates that combining PDT and nanoparticles can enhance therapeutic effects.

A 28-year-old woman was diagnosed with high-risk triple-expressor diffuse large B-cell lymphoma (DLBCL) (stage IV, IPI 4, CNS-IPI 5), with lymph node and extranodal involvement. The patient underwent first-line R-CHOP treatment, achieving a partial response with residual mediastinal uptake. A second-line platinum-based therapy with a transplant plan followed, resulting in stable disease; thus, she was considered refractory and started third-line therapy with CAR-T cells, receiving additional chemotherapy as bridging therapy.

Leaky and structurally abnormal blood vessels and increased pressure in the tumor interstitium reduce the infiltration of CAR-T cells in solid tumors, including triple-negative breast cancer (TNBC). Furthermore, high burden of tumor cells may cause reduction of infiltrating CAR-T cells and their functional exhaustion. In this study, various effector-to-target (E:T) ratio experiments are established to model the treatment using CAR-T cells in leukemia (high E:T ratio) and solid tumor (low E:T ratio).

Chronic Obstructive Pulmonary Disease (COPD) is associated with cough, sputum production, and a reduction in lung function, quality of life, and life expectancy. Currently, bronchodilator combinations (β2-agonists and muscarinic receptor antagonists, dual therapy) and bronchodilators combined with inhaled corticosteroids (ICS), triple therapy, are the mainstays for the management of COPD. However, the use of ICS in triple therapy has been shown to increase the risk of pneumonia in some patients.

Introduction: Physical therapy encompasses a broad range of treatment options, often utilized in clinical settings where pharmaceutical interventions are standard. The potential for physical therapy to contribute to sustainable healthcare by reducing environmental impact, while maintaining the quality of care, remains underexplored. This study aimed to map existing research comparing physical therapy to pharmaceuticals, with a specific focus on whether these studies address aspects of sustainable development.
