To solve the low oral bioavailability of curcumin (CUR) due to the limits imposed by gastrointestinal (GI) barrier, we constructed a nano delivery system to evaluate the effect of N-acetyl-L-cysteine (NAC) on intestinal absorption and oral bioavailability of CUR. CUR was first encapsulated in bovine serum albumin nanoparticles (CUR-BSA-NPs), and then was further modified by NAC (CUR-NBSA-NPs). In situ single-pass intestinal perfusion assay demonstrated that CUR-NBSA-NPs displayed excellent permeation and absorption rates in GI tract. Additionally, the distribution study in GI tract revealed that more NBSA-NPs were absorbed by intestinal segments compared to the BSA nanoparticles. selleck chemicals llc Plasma concentration-time curves in rats showed that AUC0-t, Cmax and MRT0-t values of CUR after oral administration of CUR-NBSA-NPs were increased to 3.25-, 4.42-, and 1.43-fold compared with that of CUR suspension. In conclusion, NAC promotes oral absorption of CUR, thereby improving its oral bioavailability.
Although prior endovascular intervention is a risk factor for inferior outcomes after infrainguinal bypass, there are few studies evaluating the effect of prior aortoiliac endovascular intervention (AIEI) on outcomes after aortofemoral bypass (AFB). We sought to determine if prior AIEI was predictive of adverse events after AFB.

The Vascular Quality Initiative was queried for all patients who underwent AFB form 2009 to 2019. Urgent/emergent cases and repeat procedures were excluded. Primary outcomes were major perioperative complications, major adverse limb event (MALE)-free survival, and long-term survival. Multivariable logistic regression identified predictors of major complications. Predictors of MALE-free survival were identified with Cox proportional hazards modeling.

There were 3,056 patients who underwent AFB; 618 had a prior AIEI. Mean age was 60.3±8.7years, and 58.7% of patients were men. There was no difference in major complications between the 2 groups (AIEI 23.8%, no AIEI 24.5%; P-value=0.emia, 95% CI 1.16-1.41; P<0.001), diabetes (HR 1.29, 95% CI 1.05-1.59; P=0.014), simultaneous peripheral vascular intervention (HR 2.06, 95% CI 1.02-4.15; P=0.044), CHF (HR 1.60, 95% CI 1.18-2.18; P=0.002), end-stage renal disease on hemodialysis (HR 5.07, 95% CI 2.45-10.48; P<0.001), and presenting hemoglobin<9g/dl (HR 1.76, 95% CI 1.02-3.02; P=0.041). One-year survival for the prior AIEI group was 94.5% (95% CI 92.2-96.1%) and 94.0% (95% CI 92.9-94.9%) for the group with no prior AIEI (logrank P=0.486). Prior AIEI did not predict any of the primary outcomes in multivariable analysis.

An endovascular-first approach for aortoiliac occlusive disease appears to be safe and does not portend to inferior results after AFB.

The aim of this study is to investigate the impact of the coronavirus disease 2019 (COVID-19) lockdown period on the number and type of vascular procedures performed in the operating theater.

A total of 38 patients who underwent 46 vascular procedures during the lockdown period of March 16th until April 30th, 2020, were included. The control groups consisted of 29 patients in 2019 and 54 patients in 2018 who underwent 36 and 66 vascular procedures, respectively, in the same time period. Data were analyzed using SPSS Statistics.

Our study shows that the lockdown during the COVID-19 pandemic resulted in a significant increase in the number of major amputations (42% in 2020 vs. 18% and 15% in 2019 and 2020, respectively; P-value 0.019). Furthermore, we observed a statistically significant difference in the degree of tissue loss as categorized by the Rutherford classification (P-value 0.007). During the lockdown period, patients presented with more extensive ischemic damage when than previous years. We observed no difference in vascular surgical care for patients with an aortic aneurysm.

Measurements taken during the lockdown period have a significant effect on non-COVID-19 vascular patient care, which leads to an increased severe morbidity. In the future, policy makers should be aware of the impact of their measurements on vulnerable patient groups such as those with peripheral arterial occlusive disease. For these patients, medical care should be easily accessible and adequate.

The aim of this study was to report the experience of one of the major "hubs" for vascular surgery in Lombardy, Italy, during the first 7weeks after total lockdown due to COVID-19 pandemic.

Data from all patients treated at our Department since the decision of the regional healthcare authorities of Lombardy to centralize surgical specialties creating a hub/spoke system (March 9, 2020) were prospectively collected and compared with a retrospectively collected cohort from the same period of year 2019. Primary study end point was defined as primary clinical success. Secondary end points were defined as in-hospital mortality and/or any in hospital major adverse event or lower limb amputation.

One hundred sixteen patients were treated (81 men, 70%; median age 71years, IQR 65-81). Thirty-two patients (28%) were addressed from spoke hospitals directly referring to our hub, 19 (16%) from hospitals belonging to other hub/spoke nets, 48 (41%) came directly from our emergency department, and 17 (15%) were already VID and COVID era were comparable in our experience.The objective of this work was to determine whether folic acid (FA) reduces the embryonic ethanol (EtOH) exposure induced behavioral and morphological defects in our zebrafish fetal alcohol spectrum disorder (FASD) model. Teratogenic effects, mortality, the excitatory light-dark locomotion (ELD), sleep (SL), thigmotaxis (TH), touch sensitivity (TS), and optomotor response (OMR) tests were evaluated in larvae (6-7 days post-fertilization) using four treatment conditions Untreated, FA, EtOH and EtOH + FA. FA reduced morphological defects on heart, eyes and swim bladder inflation seen in EtOH exposed fish. The larvae were more active in the dark than in light conditions, and EtOH reduced the swimming activity in the ELD test. EtOH affected the sleep pattern, inducing several arousal periods and increasing inactivity in zebrafish. FA reduces these toxic effects and produced more consistent inactivity during the night, reducing the arousal periods. FA also prevented the EtOH-induced defects in thigmotaxis and optomotor response of the larvae.
