RESUMO

Goat milk proteins are unique in their nutritional and functional properties and have become increasingly popular in recent years. A variety of methods have been studied for extracting and isolating these proteins, with coprecipitation being a particularly effective approach. Compared to cow milk proteins, goat milk proteins contain higher levels of certain amino acids such as tryptophan and cysteine, while maintaining similar nutritional properties. Additionally, they have superior functional properties, including better emulsifying and foaming properties, which make them an attractive option for developing new food products. Research has shown that goat milk proteins have several health benefits, including immunomodulatory effects, allergy management, anti-inflammatory, and antioxidant effects, as well as antimicrobial and anticancer properties. They have the potential to be used as a treatment for autoimmune diseases, allergies, and other immune system disorders due to their ability to modulate the production of cytokines and other immune system components. Furthermore, their antimicrobial properties can help prevent the growth of harmful bacteria and reduce the risk of infection. Future research will focus on the potential of goat milk proteins as a functional food ingredient, their effects on gut health and microbiota, and their therapeutic potential for various health conditions. This research may lead to the development of new functional foods that promote health and prevent disease, and potentially pave the way for the use of goat milk proteins as a therapeutic agent for various health conditions.

RESUMO

RATIONALE AND OBJECTIVES: To examine the clinical outcomes of yttrium-90 (Y90) transarterial radioembolization (TARE) for primary hepatocellular carcinoma (HCC) through the evaluation of a 5-year institutional experience. MATERIALS AND METHODS: This retrospective study evaluated 88 consecutive patients with primary HCC receiving Y90 TARE treatment at an academic medical center from 2017 to 2021. Disease distribution was bilobar in 60.2% of patients with an average lesion diameter of 5.0 ± 3.4 cm and Barcelona Clinic Liver Cancer stage B or C in 77% of the participants. Clinical outcomes were elucidated by examination of complications, liver function tests, biochemical response, and radiographic response. Objective response ratio (ORR) and progression-free survival (PFS) were also calculated. RESULTS: The mean administered Y90 radiation dose was 127.8 ± 20.2 Gy. No significant complications or LFT elevations occurred post-therapy. Of the 73.9% of patients with α-fetoprotein-producing tumors, 67.8% experienced a complete or partial biochemical response 1 month post-treatment. The ORR was 83.3% on 6-month imaging and PFS was 9.6 ± 8.5 months. Functional outcomes (Eastern Cooperative Oncology Group) were maintained or improved in 79.6% and 76.1% of patients by 6 months and 1 year post-treatment, respectively. The mean survival was 14.7 ± 12.1 months. At 6 months post-treatment, 77.3% of patients were downstaged to or maintained Milan criteria, which was sustained for 74.4% and 70.0% of patients 1 year and 2 years after treatment, respectively. CONCLUSION: Y90-TARE is a safe and effective therapy for primary HCC. Enduring outcomes further act as a realistic bridge to liver transplantation, with a majority of patients maintaining Milan criteria and preserving their functional status long term.

RESUMO

PURPOSE: Despite the survival benefit of transarterial chemoembolization (TACE) for unresectable hepatocellular carcinoma (HCC), a majority of tumors recur, attributed to hypovascularity and treatment resistance. Preclinical studies show that moderate radiation doses induce changes in tumor permeability and perfusion, suggesting an opportunity for TACE sensitization by radiation. In this prospective phase 1 trial, we evaluated the feasibility, safety, tolerability, response, and functional magnetic resonance imaging (MRI) changes associated with single-fraction stereotactic body radiation therapy (SBRT) followed by TACE within 24 hours. METHODS AND MATERIALS: Patients with HCC, 1 to 3 lesions, Childs-Pugh A/B liver function, and no major vascular invasion were enrolled. The primary objective was to establish the feasibility of single-dose SBRT (7.5 or 10 Gy) followed by TACE within 24 hours. Secondary endpoints included safety, tolerability, perfusional changes via functional MRI, overall response rate (ORR), clinical benefit rate (CBR), freedom from local progression, progression-free survival, and overall survival. RESULTS: Sixteen patients were enrolled, and 13 received SBRT and TACE. Median follow-up was 15.3 months. Best overall ORR and CBR were 76.9% and 92.3%, respectively. The 1- and 3-month ORR was 76.9% and 69.2%, respectively, and 1- and 3-month CBR was 92.3% and 69.2%, respectively. Median overall survival, progression-free survival, and freedom from local progression were 14.0, 5.2, and 5.9 months, respectively. Crude rates of grade 1+ and grade 2+ toxicity were 85% and 38%, respectively. No grade 3 to 4 toxicities were recorded. One grade 5 toxicity occurred due to hemorrhage 4 days after TACE. On dynamic contrast-enhanced MRI, the transfer rate constant from blood plasma to extracellular extravascular space (kpe) increased within 6 hours post-SBRT but decreased by 24 hours. CONCLUSIONS: We hypothesized a strategy of SBRT preceding TACE for the purpose of enhancing TACE delivery and efficacy and tested this strategy in a small pilot study. We found that single-dose SBRT followed by TACE within 24 hours is feasible and tolerable. Dynamic contrast-enhanced MRI revealed acute changes in tumor permeability/perfusion after SBRT. Additional studies are needed to establish the safety and efficacy of this combination and the effects of SBRT on the HCC microenvironment.

RESUMO

Radiation-induced pneumonitis (RP) is a rare complication of radioembolization with yttrium-90 ((90)Y) microspheres. The present report describes a case of RP in a patient with liver metastases from a gastrointestinal stromal tumor after radioembolization with (90)Y glass microspheres. This patient developed clinical, functional, and radiographic findings consistent with RP, with near-complete pulmonary parenchymal recovery and no clinical evidence of relapse or progressive decline in pulmonary function over a 9-month period. As clinical use of radioembolization expands, rare adverse events such as RP may become more frequent. It is essential that interventional radiologists, radiation/medical oncologists, and nuclear medicine physicians recognize this potential complication.

RESUMO

BACKGROUND: Radiomicrosphere therapy (RT) utilizing yttrium-90 (90Y) microspheres has been shown to be an effective regional treatment for primary and secondary hepatic malignancies. We sought to determine a large academic institution's experience regarding the extent and frequency of gastrointestinal complications. METHODS: Between 2004 and 2007, 27 patients underwent RT for primary or secondary hepatic malignancies. Charts were subsequently reviewed to determine the incidence and severity of GI ulceration. RESULTS: Three patients presented with gastrointestinal bleeding and underwent upper endoscopy. Review of the pretreatment angiograms showed normal vascular anatomy in one patient, sclerosed hepatic vasculature in a patient who had undergone prior chemoembolization in a second, and an aberrant left hepatic artery in a third. None had undergone prophylactic gastroduodenal artery embolization. Endoscopic findings included erythema, mucosal erosions, and large gastric ulcers. Microspheres were visible on endoscopic biopsy. In two patients, gastric ulcers were persistent at the time of repeat endoscopy 1-4 months later despite proton pump inhibitor therapy. One elderly patient who refused surgical intervention died from recurrent hemorrhage. CONCLUSION: Gastrointestinal ulceration is a known yet rarely reported complication of 90Y microsphere embolization with potentially life-threatening consequences. Once diagnosed, refractory ulcers should be considered for aggressive surgical management.

RESUMO

We presented an unusual case of ophthalmic herpes zoster masquerading as orbital cellulitis, resulting in delay in appropriate treatment. A 65-year-old woman presented with left periorbital pain and swelling of a week duration. Examination revealed periorbital edema and inflammation but no proptosis. The erythema extended onto the brow. There was no change in visual acuity and cranial nerve function was normal. She was apyrexial and all other parameters were within normal limits. The patient was admitted with an initial diagnosis of sinusitis with orbital cellulitis/dacryocystitis and intravenous co-amoxiclav and a non-steroidal anti-inflammatory drug were administered. The following day, there was little change in her condition with the ocular movements being normal and vision remaining unaffected. She was apyrexial but the periorbital swelling persisted. Computed tomography of the sinuses did not show sinusitis or a periorbital collection. The third day after admission and 10 days after the initial appearance of pain, vesicles appeared on the left forehead, which enabled a diagnosis of herpes zoster of the ophthalmic branch of the trigeminal nerve. She was then treated with acyclovir with a good result.
