Therefore, cardiovascular events may even be long-term complications of seasonal BP variation in pediatric hypertensive patients. Overall, these data strongly suggest an important effect of ambient temperature on BP in children. Additional studies in pediatric cohorts are needed to define how best to incorporate such variation into clinical practice.We previously demonstrated that immunohistochemistry for γ-H2AX, a biomarker of DNA damage, is useful for early detection of urinary bladder carcinogens in rats. In a 28-day repeated-dose study, γ-H2AX was shown to have high sensitivity for detection of bladder carcinogens. However, no reports have evaluated whether a combination of multiple biomarkers may further improve sensitivity. Accordingly, in this study, we aimed to evaluate the applicability of bladder tissue and cancer stem cell markers, including cytokeratin 14 (KRT14), aldehyde dehydrogenase 1A1 (ALDH1A1), and cluster of differentiation 44 (CD44), as complementary markers for early detection of bladder carcinogens. Bladder samples obtained from male F344 rats orally treated with 14 bladder carcinogens and five nonbladder carcinogens for 28 days were used for immunohistochemical analysis of stem cell markers. In the bladder carcinogen-treated rats, increases in KRT14, ALDH1A1, and CD44 expression were observed in 9, 10, and 10 out of 14 groups, respectively, whereas the five nonbladder carcinogens did not cause upregulation of these markers. Although most epithelial cells with KRT14 or ALDH1A1 expression were also positive for CD44, KRT14 and ALDH1A1 expression were mutually exclusive. Twelve bladder carcinogens showed increases in at least one of the three markers, indicating that the combined evaluation showed higher sensitivity than the use of individual markers alone. Importantly, two of three bladder carcinogens that did not induce γ-H2AX immunostaining showed stem cell marker expression. Our results demonstrated that these stem cell markers may be useful as complementary markers for γ-H2AX in evaluation of bladder carcinogens.Cancer patients with diabetes have an increasing risk of Dox-induced cardiotoxicity. Despite previous studies reporting benefits of dapagliflozin on the cardiovascular system, it remains unknown whether dapagliflozin has a cardioprotective effect in cancer patients with diabetes. We aimed to investigate the potential of dapagliflozin for preventing doxorubicin (Dox)-induced cardiotoxicity. Using Taiwan National Health Insurance Database, the incidence of heart failure of cancer patients with or without diabetes was investigated. Streptozotocin (STZ)-induced diabetic rats were pretreated with oral dapagliflozin for 6 weeks followed by Dox for 4 weeks via intraperitoneal injection. Sequential echocardiography was applied to assess cardiac function. For in vitro analysis, cardiomyocytes cultured in high glucose were treated with dapagliflozin at 10 μM and subsequently exposed to Dox at 1 μM. Apoptosis and endoplasmic reticulum (ER) stress-related protein expression were measured. Among the studied patients, those with diabetes had a higher risk of major adverse cardiovascular events including the development of heart failure. In diabetic rats, dapagliflozin reduced cardiac fibrosis and significantly improved cardiac function. Dapagliflozin effectively inhibited Dox-induced apoptosis and reactive oxygen species in cardiomyocytes under high glucose. Mechanistically, we showed that dapagliflozin decreased the cardiac expression of Bax and cleaved caspase 3 but increased Bcl-2. Dapagliflozin also significantly reduced ER stress-associated proteins including GRP78, PERK, eIF-2α, ATF-4, and CHOP. Our study revealed for the first time that dapagliflozin mitigated Dox-induced cardiomyocyte apoptosis in diabetes. These results indicate that dapagliflozin could be useful for preventing cardiotoxicity in diabetic cancer patients receiving Dox treatment.
Portal vein embolization (PVE) is widely used to promote the hypertrophy of a future liver remnant (FLR) and reduce posthepatectomy liver failure. The aim of this study was to evaluate the efficacy of transileocecal portal embolization (TIPE) associated with staging laparoscopy (hybrid lap-TIPE) for a planned hepatectomy in advanced hepatobiliary cancers.

The hybrid lap-TIPE procedure consisted of staging laparoscopy for complete screening of the abdominal cavity with cytoreductive surgery and subsequent TIPE. Data on hybrid lap-TIPE, performed between March 2013 and February 2020, were collected retrospectively.

Hybrid lap-TIPE was conducted for 52 patients, and a subsequent TIPE was accomplished in 42 patients (80.8%), since staging laparoscopy detected latent or unresectable factors in 13 patients (25.0%), among which 2 patients with hepatocellular carcinoma and 1 with colorectal liver metastasis received laparoscopic cytoreductive surgery for latent lesions in the FLR. Finally, radical hepatectomy was completed in 36 patients (69.2%), including 3 patients who underwent cytoreductive surgery. The most common operation was an extended right hepatectomy (50.0%), followed by right hepatectomy (30.6%), including 3 hepatopancreatoduodenectomies. The overall morbidity associated with hybrid lap-TIPE and hepatectomy was 7.1% and 41.7%, respectively. The mortality associated with hybrid lap-TIPE and hepatectomy was 0% and 5.6%, respectively. The rates of 2-year survival and 2-year disease-free survival were 64.8% and 61.9%, respectively, after hepatectomy.

Hybrid lap-TIPE is safe and could be a useful treatment option for patients with advanced hepatobiliary cancer because it can help to identify optimal candidates for PVE followed by a planned hepatectomy.

Guidelines recommend specific treatment goals for pulmonary arterial hypertension (PAH) patients functional class I or II, 6-min walk distance (6MWD) ≥ 380 to 440m, normal natriuretic peptide levels, and normal right-sided invasive hemodynamics. Only observational registry data support this recommendation. Our aim was to test these goals in a large group 1 PAH cohort against long-term survival.

We analyzed the PHIRST and TRIUMPH populations (n = 563, age 53.5 ± 14.7years, female sex 79%). The predictor variables were the treatment goals measured at the end of the placebo-controlled phase (16 and 12weeks, respectively). selleck chemicals The primary outcome was all-cause mortality at the end of follow-up during the open-label extension phase.

There were 73 deaths during median follow of 1072days (range 27 to 2177). Patients who achieved a functional class I or II had better survival. Both a 6MWD ≥ 380m and ≥ 440m were associated with lower mortality, but survival was better in patients able to walk ≥ 440m. The best long-term survival was achieved with functional class I or II and 6MWD ≥ 440m.
