1. Therapeutic Potential of 3D-Printed Nifurtimox for Chagas Disease: Effects on Survival, Parasitemia Control and Immune Modulation.
In a T. cruzi mouse model, 3D-printed amorphous nifurtimox improved dissolution/bioavailability and outperformed conventional nifurtimox in controlling parasitemia and modulating inflammatory cytokines. At 100 mg/kg, it achieved complete parasite clearance and sustained protection even under immunosuppression, with effects comparable or superior to benznidazole.
Impact: Demonstrates a formulation-driven efficacy gain and durable sterilizing activity in vivo, suggesting a practical pathway to improve Chagas therapy. The use of 3D printing to create an amorphous drug state is a translatable technological advance.
Clinical Implications: If replicated in humans, an amorphous 3D-printed nifurtimox could enable lower dosing with superior efficacy and tolerability versus conventional therapy, potentially reshaping first-line treatment for Chagas disease.
Key Findings
- 3D-printed nifurtimox (50 and 100 mg/kg) controlled parasitemia better than conventional nifurtimox and modulated inflammatory cytokines in cardiac and skeletal muscle.
- At 100 mg/kg, 3D nifurtimox achieved complete parasite clearance with sustained protection even under immunosuppression.
- Enhanced efficacy is attributed to improved dissolution/bioavailability via 3D printing, converting nifurtimox to an amorphous solid; effects were comparable or superior to benznidazole (100 mg/kg).
Methodological Strengths
- Direct head-to-head comparison with conventional nifurtimox and reference benznidazole at defined doses
- Immunosuppression challenge demonstrating durability of parasite clearance
Limitations
- Preclinical mouse study with unspecified sample size, limiting generalizability to humans
- Safety, pharmacokinetics, and long-term toxicity profiles were not detailed
Future Directions: Conduct dose-ranging GLP toxicology and pharmacokinetic studies, followed by Phase I/II trials to evaluate safety, exposure, and efficacy versus standard therapy in acute and chronic Chagas disease.
OBJECTIVE: The Trypanosoma cruzi immunopathology is sustained by a progressive inflammatory process triggered by parasite antigens, resulting in structural and functional changes in infected organs. Current etiological treatments of benznidazole and nifurtimox show limited efficacy and high toxicity, particularly during chronic infection stages. To address these limitations, a novel 3D printing formulation was applied to nifurtimox (3D nifurtimox) to improve its dissolution and reduce cytotoxicity. This study evaluated the therapeutic efficacy of 3D nifurtimox in experimental T. cruzi infection. METHODS: Female Swiss mice were infected with 4 × 10 RESULTS: 3D nifurtimox at 50 and 100 mg/kg showed more efficacy in controlling blood parasites in mice surviving and regulating inflammatory cytokine patterns in cardiac and skeletal muscle tissues than conventional nifurtimox. In addition, 3D nifurtimox 100 mg/kg demonstrated complete parasite clearance and sustained protection even under immunosuppression. The improved efficacy is likely related to enhanced dissolution and bioavailability afforded by the 3D printing process, which transformed nifurtimox into an amorphous solid state. CONCLUSION: 3D nifurtimox represents a promising new version of nifurtimox capable of being used in low doses with comparable or superior effects to benznidazole (100 mg/kg) and can be considered a promising tool for anti-T. cruzi therapies.
2. Risk factors for breast fibrosis and unfavorable cosmetic outcomes after breast conserving therapy in the contemporary treatment era: a systematic review.
Across 12 prospective studies (12,118 patients), both fibrosis and poor cosmetic outcomes after modern BCT were associated with age, larger tumors, re-resection, poor early cosmesis, higher boost dose/volume, poorer dose homogeneity, whole-breast dose, and adjuvant chemotherapy. Dose homogeneity emerged as an additional modern predictor; sequencing chemotherapy before radiotherapy may mitigate risk.
Impact: Provides an up-to-date synthesis of modifiable and non-modifiable predictors influencing fibrosis and cosmesis in BCT, informing personalized planning and sequencing of therapies.
Clinical Implications: Optimize radiotherapy planning to improve dose homogeneity and carefully select boost dose/volume; consider sequencing chemotherapy before radiotherapy in patients requiring both to reduce fibrosis/poor cosmesis risk.
Key Findings
- Twelve prospective studies (12,118 patients) were synthesized using standardized bias tools (QUIPS, Cochrane).
- Risk factors for both fibrosis and poor cosmesis included older age, larger tumor size, re-resection, poor early cosmesis, higher boost dose and volume per 10 cc, dose homogeneity index, whole-breast irradiation dose, and adjuvant chemotherapy.
- No specific risk factors were identified for complex oncoplastic techniques or ultra-hypofractionated schedules in current data.
- Dose homogeneity was newly highlighted as a modern predictor; sequencing chemotherapy before radiotherapy should be considered.
Methodological Strengths
- Prospective-only inclusion with large aggregated sample size and standardized bias assessment (QUIPS, Cochrane tools)
- Focus on contemporary techniques (oncoplastic surgery, 3D radiotherapy) increases applicability
Limitations
- Heterogeneity across studies and lack of randomized data limit causal inference
- Insufficient high-quality data for complex oncoplastic techniques and ultra-hypofractionated radiotherapy
Future Directions: Large, multidisciplinary prospective cohorts capturing detailed dosimetry (including homogeneity indices) and standardized cosmetic assessments, and trials testing treatment sequencing.
BACKGROUND: This systematic review aimed to identify risk factors for fibrosis and unfavorable cosmetic outcomes after breast conserving therapy (BCT) for breast cancer in the light of contemporary oncoplastic surgery and 3D-radiotherapy techniques. METHODS: The systematic literature search was carried out in Embase, Ovid Medline, Cochrane Central Register of Controlled Trials, and CINAHL. Studies published after 2005, reporting two or more risk factors for fibrosis or unfavorable cosmetic outcomes as primary outcomes were eligible for inclusion. Only prospective studies with 100 or more patients analyzed were included. The Quality In Prognosis Studies tool and Cochrane risk-of-bias tool were used to assess risk of bias. Patient, tumor, and treatment-related predictors were identified. RESULTS: Twelve papers investigating 12.118 patients were identified. Risk factors for both the development of fibrosis and unfavorable cosmetic outcomes were increasing age, larger tumor size, re-resection, poor early cosmetic outcomes before the start of radiotherapy, high boost dose, boost volume per 10 cc, homogeneity-index, dose whole breast irradiation, and adjuvant chemotherapy. No specific risk factors in the setting of BCT with complex oncoplastic surgery techniques or ultra-hypo fractionated radiotherapy were identified in this review. CONCLUSION: The risk factors identified in this review are largely similar to those found in 2D-radiotherapy studies; dose homogeneity was additionally identified. Administering chemotherapy before radiotherapy should be considered for patients requiring both treatments. However, the lack of sufficient high-quality data regarding BCT with (complex) oncoplastic surgery techniques and ultra-hypo fractionated radiotherapy schedules address the need for large, multidisciplinary prospective studies with long-term follow-up.
3. Comprehensive Facial Skin Rejuvenation With Long-Term Regular Intense Pulsed Light Therapy: A Real-World Study.
In a 236-patient real-world retrospective study, long-term regular IPL improved erythema, pigmentation, and wrinkle indices with no severe adverse events. Regular treatment intervals and higher total session number independently predicted better outcomes, while Fitzpatrick Type IV skin had a lower response rate.
Impact: Provides quantifiable, multi-domain evidence for long-term IPL efficacy and identifies actionable dosing cadence predictors, supporting protocol optimization in aesthetic practice.
Clinical Implications: Adopt regular IPL treatment intervals and adequate total sessions to maximize cumulative rejuvenation effects; counsel Fitzpatrick Type IV patients on lower expected response.
Key Findings
- Significant improvements in erythema, pigmentation, and wrinkle indices after long-term IPL (all p < 0.05).
- Regular treatment intervals (OR = 13.62) and higher total session number (OR = 3.80) independently predicted better outcomes.
- Fitzpatrick Type IV skin had lower response rates (OR = 0.12, p = 0.001); no severe adverse events were reported.
Methodological Strengths
- Objective VISIA imaging used to quantify erythema, pigmentation, and wrinkles
- Multivariable logistic regression identified independent predictors
Limitations
- Retrospective design without a control group introduces selection and confounding biases
- Single-technology, single-setting real-world data may limit generalizability, especially to darker skin types
Future Directions: Prospective controlled trials stratified by Fitzpatrick type and interval cadence to validate predictors and optimize IPL protocols.
BACKGROUND: Intense pulsed light (IPL) therapy is widely used for facial rejuvenation, targeting vascular, pigmentary, and textural changes. However, comprehensive, real-world evidence evaluating long-term, regular IPL treatment across multiple dimensions of skin improvement remains limited. OBJECTIVES: This study aimed to assess the efficacy and safety of long-term, regular IPL therapy in improving facial erythema, pigmentation, and wrinkles, and to identify predictors of favorable response. METHODS: This retrospective real-world study included 236 patients who underwent six or more IPL sessions between 2020 and 2025. Patients were categorized as acne, rosacea, or cosmetic subjects. VISIA imaging quantified erythema, pigmentation, and wrinkle indices, while the Global Aesthetic Improvement Scale (GAIS) was used to assess aesthetic outcomes. Logistic regression identified predictors of good response. RESULTS: Significant improvements were observed in erythema, pigmentation, and wrinkle indices after treatment (all p < 0.05). Regular treatment intervals and total number of sessions were independently associated with better outcomes (OR = 13.62 and 3.80, respectively, both p < 0.05). Patients with Fitzpatrick Type IV skin showed lower response rates (OR = 0.12, p = 0.001). VISIA analyses demonstrated quantifiable reductions in erythema and pigmentation areas, while wrinkles showed notable textural improvement. No severe adverse events occurred. CONCLUSIONS: Long-term, regular IPL therapy effectively improves facial erythema, pigmentation, and wrinkles, confirming its value as a comprehensive rejuvenation strategy. Regular treatment intervals optimize cumulative effects, while objective imaging enhances precision in outcome evaluation. These findings support IPL as a safe, evidence-based, and multidimensional approach to long-term facial rejuvenation.
