INTRODUCTION: Type 2 diabetes mellitus (T2DM) and obesity are both related to increased risk of cardiovascular disease and mortality. Early atherosclerotic vascular changes can be detected by non-invasive tests like carotid artery intima-media thickness (cIMT) and pulse wave velocity (PWV). Both cIMT and PWV are significantly impaired in T2DM patients and in obese patients, but the additional effect of T2DM on these vascular measurements in obese subjects has not been evaluated. METHODS: Two hundred morbidly obese patients with or without T2DM were enrolled in a prospective cohort study and underwent extensive laboratory testing, including cIMT and PWV measurements...

Hydatid cyst (echinococcosis) is an endemic parasitic disease, usually encountered in those dealing with agriculture and livestock. The most frequently affected organs are the liver and the lungs. The disease is very rarely encountered in soft tissues. Diagnosing a soft-tissue hydatid cyst may be challenging unless the mass possesses the characteristic features of a hydatid cyst. Soft-tissue hydatid cysts may be treated percutaneously, just like those encountered in the liver. In this case report, we present the radiological findings and modified percutaneous aspiration-injection-reaspiration (PAIR) treatment of a hydatid cyst located in the posterior aspect of the thigh...

Biological soil crusts (biocrusts) account for a substantial portion of primary production in dryland ecosystems. They successionally mature to deliver a suite of ecosystem services, such as carbon sequestration, water retention and nutrient cycling, and climate regulation. Biocrust assemblages are extremely well adapted to survive desiccation and to rapidly take advantage of the periodic precipitation events typical of arid ecosystems. Here we focus on the wetting response of incipient cyanobacterial crusts as they mature from "light" to "dark...

We compared the efficacy and safety of low-molecular-weight heparins (LMWHs) in patients with cancer who are at low risk of venous thromboembolism (VTE). Patients were treated by medical oncologists in Turkey at 15 sites, where they were enrolled and followed up for a period of 12 months. Due to the study design, there was no specific treatment protocol for LMWH. Primary end points were efficacy and the time to change in VTE status. Of the included 250 patients, 239 (95.6%), 176 (70.4%), 130 (52.0%), and 91 (36...

Despite of high rates of adverse childhood experiences (ACEs) in pathological gamblers, researchers have rarely studied which types of ACEs often co-occur and how these profiles of ACEs are related to current psychopathology. We aimed to identify profiles of ACEs in pathological gamblers and examined how these profiles were related to gambling-related characteristics and current general psychopathology. In 329 current or lifetime pathological gamblers, diagnosed with the Composite Diagnostic Interview for DSM-IV, 10 types of ACEs were measured using the Adverse Childhood Experiences Questionnaire...

The aim of this study was to assess whether serum markers would be useful as a new predictor of preterm birth in patients with spontaneous, late preterm labour. Patients diagnosed with late preterm labour were divided into preterm delivery (229 patients) and term delivery (178 patients) groups. The two groups were compared in terms of clinical characteristics and levels of serum markers (leukocyte subtypes, platelet, C-reactive protein [CRP], neutrophil to lymphocyte ratio [NLR] and platelet to lymphocyte ratio [PLR]), which were obtained at admission...

Study Design: Atlas fractures are evaluated according to the fracture type and ligamentous injury. External immobilization may result in fracture nonunion. Objective: The ideal treatment method for non-stabilized atlas fractures is limited fixation without restricting the range of motion of the atlantoaxial and atlantooccipital joints. Summary of Background Data: Such a result can be established by using either anterior fixation or posterior lateral mass fixation...

INTRODUCTION: Hypertrophic olivary degeneration (HOD) occurs as a result of posterior fossa or brainstem lesions that disrupt the dentato-rubro-olivary tract, well known as the Guillain-Mollaret triangle. Clinical and radiological hallmarks of this condition are palatal myoclonus and T2 hyperintensity of the inferior olivary complex on MRI, respectively. Since symptomatic HOD may complicate the recovery of patients with posterior fossa or brainstem lesions, the purpose of this study is to evaluate clinical and imaging findings of patients with HOD...

BACKGROUND: Systolic dyssynchrony index (SDI) using three-dimensional echocardiography (3DE) was shown to be a reliable measure of left ventricular (LV) dyssynchrony. However, the prognostic value of SDI on long-term outcomes after cardiac resynchronization therapy (CRT) remains unknown. METHODS AND RESULTS: A total of 414 patients (mean age 67±10 years, 60% ischemic etiology) with 3DE evaluation before CRT implantation were included. SDI was evaluated as continuous value and in quartiles...

In this paper, we propose a vectorized noncircular MUSIC (VNCM) algorithm based on the concept of the coarray, which can construct the difference and sum (diff-sum) coarray, for direction finding of the noncircular (NC) quasi-stationary sources. Utilizing both the NC property and the concept of the Khatri-Rao product, the proposed method can be applied to not only the ULA but also sparse arrays. In addition, we utilize the quasi-stationary characteristic instead of the spatial smoothing method to solve the coherent issue generated by the Khatri-Rao product operation so that the available degree of freedom (DOF) of the constructed virtual array will not be reduced by half...

AIM: Today, spinal cord injury (SCI) can be rehabilitated but cannot be treated adequately. This experimental study was conducted to investigate possible beneficial effects of methylprednisolone and parecoxib in treatment of SCI. MATERIALS AND METHODS: Forty-eight male Wistar albino rats were assigned into CONTROL, acute (MP-A, PX-A, and PXMP-A), and subacute (MP-S, PX-S, and PXMP-S) stage groups. Then, to induce SCI, a temporary aneurysm clip was applied to the spinal cord following T7-8 laminectomy, except in the CONTROL group...

Direction-of-arrival (DOA) and range estimation is an important issue of sonar signal processing. In this paper, a novel approach using Hilbert-Huang transform (HHT) is proposed for joint bearing and range estimation of multiple targets based on a uniform linear array (ULA) of hydrophones. The structure of this ULA based on micro-electro-mechanical systems (MEMS) technology, and thus has attractive features of small size, high sensitivity and low cost, and is suitable for Autonomous Underwater Vehicle (AUV) operations...

Long-term epigenetic reprogramming of innate immune cells in response to microbes, also termed "trained immunity," causes prolonged altered cellular functionality to protect from secondary infections. Here, we investigated whether sterile triggers of inflammation induce trained immunity and thereby influence innate immune responses. Western diet (WD) feeding of Ldlr -/- mice induced systemic inflammation, which was undetectable in serum soon after mice were shifted back to a chow diet (CD). In contrast, myeloid cell responses toward innate stimuli remained broadly augmented...

INTRODUCTION: Patients with Su Type III fractures based on total knee arthroplasty (TKA) constitute a patient group with problematic treatment and management. Although it has difficulties, open reduction and internal fixation is one of the treatment options. METHOD: A retrospective evaluation was made of 22 patients surgically treated in our clinic with double locking, low contact titanium plate and screw for a Su Type III periprosthetic fracture based on TKA. The patients were evaluated with bone mineral densitometry, postoperative Knee Society Score (KSS), WOMAC and radiological evaluations...
