The results of this study suggest that neuroticism may produce variations in young people's identity development.A mononuclear Mn(I) pincer complex [Mn(Ph2 PCH2 SiMe2 )2 NH(CO)2 Br] was disclosed to catalyze the pinacolborane (HBpin)-based CO2 hydroboration reaction. Density functional calculations were conducted to reveal the reaction mechanism. The calculations showed that the reaction mechanism could be divided into four stages (1) the addition of HBpin to the unsaturated catalyst C1; (2) the reduction of CO2 to HCOOBpin; (3) the reduction of HCOOBpin to HCHO; (4) the reduction of HCHO to CH3 OBpin. The activation of HBpin is the ligand-assisted addition of HBpin to the unsaturated Mn(I)-N complex C1 generated by the elimination of HBr from the Mn(I) pincer catalyst. The sequential substrate reductions share a common mechanism, and every hydroboration commences with the nucleophilic attack of the Mn(I)-H to the electron-deficient carbon centers. C188-9 mw The hydride transfer from Mn(I) to HCOOBpin was found to be the rate-limiting step for the whole catalytic reaction, with a total barrier of 27.0 kcal/mol, which fits well with the experimental observations at 90 °C. The reactivity trend of CO2 , HCOOBpin, HCHO, and CH3 OBpin was analyzed through both thermodynamic and kinetic analysis, in the following order, namely HCHO>CO2 >HCOOBpin≫CH3 OBpin. Importantly, the very high barrier for the reduction of CH3 OBpin to form CH4 reconciles with the fact that methane was not observed in this catalytic reaction.

Portal hypertension (PH) is associated with complications including refractory ascites and variceal haemorrhage and can be treated endovascularly with a Transjugular Intrahepatic Portosystemic Shunt (TIPS). Portal vein puncture during TIPS using real-time transabdominal ultrasound guidance is one of many portal vein puncture techniques and is seldom used compared with other methods. The purpose of this manuscript is to describe this technique and its associated procedural outcomes at a quaternary liver transplant hospital.

Clinical data of all patients who underwent ultrasound-guided TIPS at our institution between 1 January 2009 and 1 January 2019 were retrospectively obtained from electronic medical records and reviewed. Patient demographics, indications, procedural outcomes and complications were recorded.

Forty-four ultrasound-guided TIPS procedures were performed during the study period. The most common indication for TIPS was refractory ascites (n=26; 57%) and variceal haemorrhage (n=12; 26%). Teciated with lower intraprocedural complication rates, fluoroscopy times, contrast volumes and radiation doses in our experience. Radiation doses, FTs and contrast volumes were also considerably lower than recommended limits.

This study aimed to identify patients with stage IB1-IIA2 cervical cancer at low risk for lymph node metastasis (LNM) using preoperative magnetic resonance imaging (MRI) parameters.

Clinical and MRI data of patients with stage IB1-IIA2 cervical cancer who underwent radical surgery between 2010 and 2015 were retrospectively reviewed. Clinical stage IB1-IIA2 cervical cancer was diagnosed according to the 2009 International Federation of Gynecology and Obstetrics staging system. The low-risk criteria for LNM were identified using logistic regression analysis. The performance of the logistic regression analysis was estimated through receiver operating characteristic curve analysis.

Of 453 patients, 105 (23.2%) exhibited pathological LNM (p-LNM). The maximal tumor diameter (adjusted odds ratio [aOR], 1.586; 95% confidence interval [CI], 1.312-1.916; p<0.001) and LNM (aOR, 2.384; 95% CI, 1.418-4.007; p=0.001) on preoperative MRI (m-LNM) were identified as independent risk factors for p-LNM using a multivariate logistic analysis. The p-LNM rate was 4.0% for low-risk patients (n=124) identified using the current criteria (maximal tumor diameter <3.0cm and no sign of m-LNM). The 5-year disease-free survival rate of low-risk patients was significantly greater than the rate of patients with a maximal tumor diameter ˃3.0cm and/or signs of m-LNM (90.4% vs. 82.1%; p=0.033).

The low-risk criteria for p-LNM were a maximal tumor diameter <3.0cm and no sign of m-LNM. Patients with stage IB1-IIA2 cervical cancer at low risk for m-LNM could be candidates for radical surgery; hence, they have a lesser need for adjuvant chemoradiotherapy, thus avoiding the severe comorbidities it causes.

The low-risk criteria for p-LNM were a maximal tumor diameter less then 3.0 cm and no sign of m-LNM. Patients with stage IB1-IIA2 cervical cancer at low risk for m-LNM could be candidates for radical surgery; hence, they have a lesser need for adjuvant chemoradiotherapy, thus avoiding the severe comorbidities it causes.Non-alcoholic liver disease (NAFLD) is a metabolic liver disease associated with visceral adiposity and insulin resistance. Recently, NAFLD has been described in lean individuals who additionally have impaired metabolic parameters similar to their non-lean counterparts. We aimed to explore this further in Saudi Arabia. From 2016 to 2019, we prospectively studied a group of newly diagnosed NAFLD patients at a tertiary hospital in Saudi Arabia. Patients were classified into three groups lean (body mass index [BMI] less then 25), overweight (BMI ≥25 and less then 30), and obese (BMI ≥30). We made comparisons between these groups on basic clinical, demographic, and laboratory parameters. In total, 1753 patients were recruited and 1262 patients met the inclusion criteria. Altogether, 159 (12.6%), 365 (29%), and 737 (58.4%) patients were in the lean, overweight, and obese categories, respectively. Lean NAFLD patients were, on average, younger than those in the overweight group (mean 49.95 ± 15.3) and had a significantly higher high-density lipoprotein value (HDL) (mean 52.56 ± 16.27). Sex, hyperlipidemia, type 2 diabetes, and hypertension were significantly associated with BMI. Lean NAFLD patients displayed the features of metabolic syndrome including elevated glycosylated hemoglobin and abnormal lipid profile but had higher serum HDL. This is in contrast to the widely held belief that lean individuals have no dysmetabolic changes compared to overweight individuals. Recognition of this problem is essential so that lean NAFLD patients can be screened for metabolic changes and managed appropriately to prevent complications.
