We aimed to explore the impact of 7-Fr sheaths on the incidence of early radial artery occlusion (RAO) after transradial coronary intervention (TRI) in Chinese patients. RAO precludes future use of the vessel for vascular access. Transradial catheterization is usually performed via 5-Fr or 6-Fr catheters; 7-Fr sheath insertion enables complex coronary interventions but may increase the RAO risk. We prospectively enrolled 130 consecutive patients undergoing complex TRI using 7-Fr sheaths. Radial artery ultrasound assessment was performed before and after TRI. Early RAO was defined as the absence of flow on ultrasound within 6-24 hr after TRI. Multivariate logistic regression was used to determine the factors related to early RAO after TRI. 7-Fr sheaths were mainly used for chronic total occlusion (44.6%), bifurcation (30.0%), and tortuous calcification (25.4%) lesions. All patients were successfully sheathed. Percutaneous coronary intervention (PCI) procedural success was 96.2%; 119 patients (91.5%) had preserved radial artery patency after TRI. All 11 RAO cases (8.5%) were asymptomatic. The radial artery diameter was significantly larger postoperatively (3.1 ± 0.4 mm) than preoperatively (2.6 ± 0.5 mm) (p < .001). No parameters significantly differed between patients with and without RAO. TRI history was the only independent risk factor of early RAO (odds ratio 6.047, 95% confidence interval 1.100-33.253, p = .039). 7-Fr sheath use after transradial access for complex PCI is feasible and safe. Evaluating the radial artery within 24 hr after TRI allows timely RAO recognition, important for taking measures to maintain radial artery patency and preserve access for future TRIs. 7-Fr sheath use after transradial access for complex PCI is feasible and safe.

Readiness for practice is an ongoing concern in surgery. Surgeons who have completed general surgery training are expected to be proficient in performing common emergency procedures. The aim of this study was to assess the experience and autonomy of general surgery trainees in New Zealand in 10 emergency general surgery procedures, and identify factors associated with reaching primary operator (PO) thresholds. Operative logbook data from all New Zealand general surgery trainees from 2013 to 2017 were analysed. Data for 10 emergency general surgery procedures were extracted to determine PO and autonomous PO (mentor not scrubbed) rates. A threshold of 70% for PO and APO rates was used to define two levels of proficiency. A total of 120 trainees performed 40 865 included procedures. https://www.selleckchem.com/products/isoproterenol-sulfate-dihydrate.html Trainees met the PO threshold for all procedures by Surgical Education and Training (SET) 5. The APO threshold was met for three of 10 procedures (appendicectomy, drainage of perianal abscess and perforated peptic ulcer repair). Final APO rates for the other procedures ranged from 18% to 58%. On multivariate analysis, SET year and case volume were associated with increased odds of meeting the PO and APO thresholds. Female trainees were less likely to reach the PO and APO thresholds for three of 10 and four of 10 procedures, respectively. Trainees had increasing PO and autonomous PO rates over the course of their training. Graduating New Zealand general surgeons likely have sufficient operative experience in emergency general surgery procedures. However, rates of autonomy are lower, and further research is needed to determine whether this affects readiness for independent practice.

Obesity alters the pharmacokinetic (PK) properties of drugs making it difficult to determine the appropriate dose when administering weight-based medications. Alternative descriptors of body weight, such as lean body mass (LBM) and ideal body weight (IBW), are sometimes used in these situations. We performed a single-centre, randomized, controlled, open-label, 3×3 crossover trial to determine whether recombinant factor VIII (rFVIII) dosing based on LBM and IBW achieves a targeted FVIII recovery with better precision than based on total body weight (TBW) in overweight and obese, adult males with haemophilia A. Participants were randomized to 1 of 6 possible FVIII concentrate dosing sequence scenarios (TBW, LBM and IBW). Recombinant FVIII was administered on 3 separate weeks following a washout period of at least 72hours. A total of 19 participants were randomized and completed the study. FVIII recovery was lower at 30 minutes post-rFVIII infusion in LBM vs TBW and IBW vs TBW-based dosing, mean difference -0.38 (95% CI -0.56, -0.20) and -0.28 (95% CI -0.47, -0.10) IU/dL per IU/kg, respectively. In LBM vs TBW and IBW vs TBW-based dosing, there was a non-significant increase in the proportion of participants with a targeted FVIII recovery of 2.00±0.20IU/dl per IU/kg, OR=1.93 (95% CI 0.44, 8.55) and OR=3.65 (0.80, 16.72), respectively. Based on our study's findings, overweight and obese patients with haemophilia A may benefit from an individualized PK analysis using LBM and IBW to determine the most accurate, and potentially cost-effective, method of achieving targeted FVIII recovery.

To investigate paediatric outpatients' nutritional status using bioelectrical impedance analysis and anthropometric z-scores. A retrospective data analysis of tertiary paediatric hospital outpatients from 2017 to 2019 was conducted. Patients were categorised into three groups (non-illness, illness and simple obesity) according to clinical diagnoses. The nutritional status was evaluated using anthropometric and bioelectrical impedance analysis. In addition, body composition measurements of patients in three subgroups of the illness group and age- and gender-matched healthy controls were compared. A total of 2015 paediatric outpatients were enrolled. According to body mass index z-scores, undernutrition prevalence among participants was 14.0% (non-illness group, 21.3%; illness group, 11.4%). Body composition measurements indicated that 41.6% of participants had a low fat-free mass index, and the proportions of participants with a low fat-free mass index in the non-illness, illness and simple obesity groups were 48.
