Overactivation of kynurenine pathway, particularly overactivation of indoleamine 2,3-dioxygenase (IDO) predicts poor prognosis of several cancers such as gastrointestinal cancers, gynecological cancers, hematologic malignancies, breast cancer, lung cancer, glioma, melanoma, prostate cancer and pancreatic cancer. Furthermore, kynurenine increases the invasion, metastasis and chemoresistance of cancer cells. Recently, IDO inhibitors entered clinical trials and successfully passed their safety tests and showed promising therapeutic efficacy for cancers such as melanoma, brain cancer, renal cell carcinoma, prostate cancer and pancreatic cancer. However, a phase III trial of epacadostat, an IDO inhibitor, could not increase the efficacy of treatment with pembrolizumab for melanoma. In this review the expanding knowledge towards kynurenine pathway and its application in each cancer is discussed separately.Cardiovascular diseases are the leading cause of death and morbidity worldwide. Atherosclerotic cardiovascular disease (ASCVD) is affected by both environmental and genetic factors. Microenvironmental disorders of the human gut flora are associated with a variety of health problems, not only gastrointestinal diseases, such as inflammatory bowel disease, but also extralintestinal organs. Hydrogen sulfide (H2S) is the third gas signaling molecule other than nitric oxide and carbon monoxide. In the cardiovascular system, H2S plays important roles in the regulation of blood pressure, angiogenesis, smooth muscle cell proliferation and apoptosis, anti-oxidative stress, cardiac functions. This review is aiming to explore the potential role of gut microbiota in the development of atherosclerosis through hydrogen sulfide production as a novel therapeutic direction for atherosclerosis.
Egg allergy is the second most common food allergy in children. Persistent food allergy increases the risk of anaphylaxis and reduces the quality of life.
To determine the efficacy of oral immunotherapy (OIT) with raw egg white powder and study its effects on humoral responses in children with persistent egg allergy.
Fifty children aged 6 to 17 years with egg allergy, diagnosed by double-blind, placebo-controlled food challenge, were randomized 32 to 8 months of OIT with a maintenance dose of 1 g of egg white protein or 6 months of avoidance after which the avoidance group crossed over to OIT. We examined changes in IgE, IgG
, and IgA concentrations to Gal d 1-4 during OIT compared with avoidance and assessed clinical reactivity at 8 and 18 months.
After 8 months, 22 of 50 children (44%) on OIT and 1 of 21 (4.8%) on egg avoidance were desensitized to the target dose, 23 of 50 (46%) were partially desensitized (dose <1 g), and 5 of 50 (10%) discontinued. IgG
concentrations to Gal d 1-4 and IgA to Gal d 1-2 increased significantly, whereas IgE to Gal d 2 decreased. A heatmap analysis of the IgE patterns revealed 3 distinct clusters linked with the clinical outcome. High baseline egg white-specific IgE and polysensitization to Gal d 1-4 related with failure to achieve the maintenance dose at 8 months. After 18 months of treatment, 36 of 50 patients (72%) were desensitized and 8 of 50 (16%) partially desensitized.
OIT with raw egg enables liberation of egg products into the daily diet in most patients. Subjects with high egg white-specific IgE concentrations and sensitization to multiple egg allergen components at baseline benefit from prolonged treatment.

We compared the long-term outcomes of small and large diameter balloon angioplasty for Budd-Chiari syndrome (BCS) with inferior vena cava (IVC) involvement in a retrospective cohort study.
Of 119 patients with BCS and IVC involvement, 23 had undergone small diameter balloon angioplasty (diameter, 14-20mm; group A) and 96 had undergone large diameter balloon angioplasty (diameter, 24-30mm; group B). The patients were considered cured clinically if the IVC was patent with no symptom or signs evident.
From January 2010 to December 2016, 119 BCS patients with IVC involvement had undergone balloon angioplasty, with angioplasty successful in all 119 patients. One patient died of pulmonary embolism after dilation in group A. TGF-beta inhibitor Abdominal pain was the most common complication during dilation and was experienced by significantly more patients in group B (77.1%) than in group A (47.8%; P= .009). Of the 119 patients, 91 (76.5%) were considered cured, with significantly more patients in group B (82.3%) than in group A (52.2%; P= .005). The mean follow-up period was 41.3± 2.2months. In group B, the 1-, 3-, and 5-year primary and secondary patency rates were 82.2%± 4.2%, 69.8%± 5.4%, and 54.0%± 7.0% and 97.5%± 1.7%, 92.5%± 3.3%, and 90.2%± 3.9%, respectively. The patency rates at all follow-up intervals were lower in group A than in group B. The clinical response rate in group B was also significantly greater than that in group A (96.9% vs 78.3%; P= .007). The 1-, 3-, and 5-year survival rates were 100%, 88.7%± 7.6%, and 88.7%± 7.6% and 96.5%± 2.0%, 92.5%± 3.0%, and 86.0%± 5.4% in groups A and B, respectively.
Large diameter balloon angioplasty is safe and effective for BCS patients with IVC involvement, yielding better patency rates and long-term outcomes compared with small diameter balloon angioplasty.

Misleading historical nomenclature, such as the May-Thurner, pelvic congestion, and nutcracker syndromes, often fails to recognize the interrelationship of many pelvic symptoms and their underlying pathophysiology. Based on a perceived need, the American Vein and Lymphatic Society convened an international, multidisciplinary panel charged with the development of a discriminative classification instrument for PeVD. This instrument, the Symptoms-Varices-Pathophysiology ("SVP") classification for PeVD, includes three domains-Symptoms (S), Varices (V), and Pathophysiology (P), with the pathophysiology domain encompassing the Anatomic (A), Hemodynamic (H), and Etiologic (E) features of the patient's disease. An individual patient's classification is designated as SVPA,H,E. For patients with pelvic origin lower extremity signs or symptoms, the SVP instrument is complementary to and should be used in conjunction with the Clinical-Etiologic-Anatomic-Physiologic (CEAP) classification.
