We analyzed patients with left ventricular assist device (LVAD) related and specific infection, and aimed to determine whether surgical technique implantation affect the frequency of infection.

We retrospectively analyzed the data of 99 patients who received LVAD at our department between June 2013 and June 2019. Patients were divided into two groups according to the surgical technique. Group A (

 = 58) was conventional sternotomy (CS) and group B (

 = 41) was on-pump minimally invasive left thoracotomy (MILT). Demographics, preoperative risk factors, LVAD infections, surgical incision site, driveline site, and outcomes were compared between these two groups.

Mean follow up time was 589 ± 480 (31-2171) days. Infection was detected in 34% (41/99) of LVAD patients. Admission to emergency department and intensive care unit (ICU) in last 6 months were significantly higher in MILT group. There was no difference between the two groups in terms of driveline exit site infection (CS 28%, MILT 27%) (

 > 0.05). Seven (17%) patients had infection in the thoracotomy incision site area in the MILT group. The rate of ICU hospitalization in the last 6 months was seen as the only independent risk factor increasing the frequency of infection (R = 0.30;

 = 0.016). Survival analysis at 60 days, 1 year and 2 years showed no difference between the two groups (

 = 0.09).

Despite advances in pump technology and surgical technique, infection is still an important cause of mortality and morbidity.

Loeys-Dietz syndrome (LDS) is a rare genetic connective tissue disorder resulting from TGF-ß signaling pathway defects and characterized by a wide spectrum of aortic aneurysm, arterial tortuosity, and various extravascular abnormalities. This study describes the audiologic, otologic, and craniofacial manifestations of LDS.

Consecutive cross-sectional study.

Tertiary medical research institute.

Audiologic and clinical evaluations were conducted among 36 patients (mean ± SD age, 24 ± 17 years; 54% female) with genetically confirmed LDS. Cases were categorized into genetically based LDS types 1 to 4 (

,

, respectively). Audiometric characteristics included degree and type of hearing loss subclinical, conductive, mixed, and sensorineural.

LDS types 1 to 4 included 11, 13, 5, and 7 patients, respectively. In LDS-1, 27% had bilateral conductive hearing loss; 9%, unilateral mixed; and 36%, subclinical. In LDS-2, 38% had conductive hearing loss and 38% subclinical. In LDS-3 and LDS-4, 40% and 43%sent only in LDS-3 and LDS-4. These LDS-associated key clinical presentations may facilitate an early diagnosis of LDS and thus prompt intervention to prevent related detrimental outcomes.In our aging population, there is an increased incidence of concurrent IVC filter and central venous catheter use. One of the risks of concurrent use is filter embolization, which almost always occurs due to the J-tipped guidewire. Zileuton in vivo In this case, we describe the successful placement of a central venous catheter in the femoral vein in a patient with an IVC filter. Some guidelines exist concerning CVC placement in patients with IVC filters, and this case highlights the benefits of placing a CVC in the femoral vein. While little research exists regarding higher rates of IVC filter embolization in internal jugular and subclavian vein access sites, we hypothesize it is due to the conical shape of IVC filters.

High-flow arteriovenous fistulae (HF-AVF) may lead to adverse cardiac remodeling in hemodialysis patients. We have investigated whether a novel external stent is safe and effective in reducing and stabilizing flow rates during a 1-year follow-up after HF-AVF reconstruction.

All patients with HF-AVF (access flow rate ⩾ 1500 ml/min), who underwent HF-AVF reconstruction with external stenting in two centers between June 2018 and May 2020, were included in this retrospective analysis. During HF-AVF reconstruction, the dilated vein segment was resected, underwent volume reduction, and was externally stabilized using a braided cobalt-chromium external stent. AVF flow rates were assessed preoperatively, intraoperatively, and at follow up visits using duplex ultrasound.

Forty-three HF-AVFs in 42 patients were reconstructed and supported with an external stent (mean age 49 years, range 20-86 years; 74% men). Fifty-one percent were forearm AVFs, 49% were upper arm. The mean preoperative flow rate was 2622 ± 893 muired to evaluate the durability of this procedure over the longer term and assess its effect on cardiac remodeling.To improve load capacity and transmission characteristics of crossed-axis helical gear drive, a generation approach of the gear pair with small-angle based on the curve contact element is proposed. Contact principle based on spatial curve meshing relationships is introduced and geometric models of tooth profiles are developed according to a pair of mated conjugate curves. Furthermore, a mathematical model of crossed-axis helical gear drive with small-angle is established. Numerical examples are illustrated for this research using the 10° shaft angle, and the computerized simulation is also developed based on the solid models. According to gear geometry and finite element method, general characteristics including undercutting conditions, sliding ratios and contact stress for tooth profiles are analyzed. Comparisons with crossed-axis involute gears are also carried out. Finally, the gear prototype is processed using the gear milling method and a basic performance test is conducted. Analysis results show that the new gear pair has well contact characteristics. Further studies on the dynamic analysis and precision manufacturing method will be carried out.Education is regarded as an avenue for success while the under-educated are disproportionately more likely to be incarcerated and remain within the correctional system. Current prison reforms have focused on increasing access to educational programming. However, these programs are not designed to address the lack of control, poor self-regulation, low emotional intelligence, inadequate social skills, or lack of internal motivation that hinder progress. Art therapy has been found effective in mitigating these impediments. Recognizing this, a partnership arose between a state Department of Corrections and a State University's graduate art therapy program out of which emerged an Art Therapy in Prisons Program, funded through the Individuals with Disabilities Education Act. Two art therapists provided services to youthful male and female offenders in four institutions to assuage these obstacles. This article explores the genesis and development of this program, and the flexible adjustments required to address the impending COVID-19.
