It is shown that the proposed modeling approach can predict the field-dependent shear yield stress much better than the single-chain model. In addition, it is identified that the shear yield stress is increased as the particle volume fraction increases and surfactant coating thickness decreases. SKIII It is believed that the proposed constitutive model can be effectively used to estimate the field-dependent shear yield stress of MRFs with a high concentration of iron particles.The purpose of this study was to identify the significant risk factors of urinary bladder recurrence (UBR) after nephroureterectomy (NUx) in patients with upper tract urothelial carcinoma (UTUC). A total of 550 patients diagnosed with UTUC between January 2001 and December 2015 were included in this retrospective study. The median age of our patients was 68 (range 24-93) and the median follow-up time after NUx was 40.3 months (range 8-191). The most important censored point of this study was the first episode of UBR. Of the 550 patients, UBR occurred in 164 patients (29.8%). One hundred and forty-two (86.6%) patients with UBR were identified within two years after NUx for UTUC, with the median time interval between NUx and UBR being 8.4 months (range 3-59.8). Through univariate analysis, the positive surgical margin (p = 0.049) and tumor multifocality (p = 0.024) were both significant prognostic factors for UBR-free survival after NUx in patients with UTUC. However, only tumor multifocality (p = 0.037) remained a significant prognostic factor by multivariate analysis. In conclusion, tumor multifocality is a significant risk factor of UBR after nephroureterectomy in patients with upper tract urothelial carcinoma.Middle East respiratory syndrome (MERS) is a respiratory disease caused by a zoonotic coronavirus (MERS-CoV). Camel handlers, including slaughterhouse workers and herders, are at risk of acquiring MERS-CoV infections. However, there is limited evidence of infections among camel handlers in Africa. The purpose of this study was to determine the presence of antibodies to MERS-CoV in high-risk groups in Kenya. Sera collected from 93 camel handlers, 58 slaughterhouse workers and 35 camel herders, were screened for MERS-CoV antibodies using ELISA and PRNT. We found four seropositive slaughterhouse workers by PRNT. Risk factors amongst the slaughterhouse workers included being the slaughterman (the person who cuts the throat of the camel) and drinking camel blood. Further research is required to understand the epidemiology of MERS-CoV in Africa in relation to occupational risk, with a need for additional studies on the transmission of MERS-CoV from dromedary camels to humans, seroprevalence and associated risk factors.Backgound Traditional anthropometrics such as body mass index (BMI) or waist circumference (WC) do not fully capture the complex biology of body fat (BF) in the elderly. The Clinica Universidad de Navarra-Body Adiposity Estimator (CUN-BAE) index, based on BMI, is proposed as a better indicator of BF. However, its relation with BMI is not clear. The aim was to compare the agreement between CUN-BAE, BMI, and WC in those aged ≥50 years. Methods A cross-sectional sample of 3153 Caucasian healthy adults was taken from the MCC-Spain study. The Pearson's correlation and its 95% confidence interval (CI), adiposity distribution, and Kappa Index (95%CI) were calculated. Results The correlation of CUN-BAE with WC is 0.18 (95%CI 0.14-0.21) and that with BMI is moderate (r 0.58; 95%CI 0.55-0.60), but both increased strongly by sex. Agreement (normal weight/overweight/obesity) of CUN-BAE with BMI is 7% and with WC is 18%. Conclusions The correlation and the degree of agreement of CUN-BAE with BMI and WC are low in individuals aged over 50, but it is higher by sex. Thus, this different criterion of obesity may have clinical applications. More studies with a gold standard are needed to evaluate the CUN-BAE in elderly adults.This study aimed to assess body image impairments of individuals with Marfan syndrome and to determine to what extent psychological, physical, and sociodemographic factors influence body image. We assessed the physical fitness and psychosocial health of 42 patients with Marfan syndrome at the beginning of an inpatient rehabilitation program. All participants filled out a body image questionnaire consisting of two scales (1) Negative Body Evaluation and (2) Vital Body Dynamics. We compared body image data of the study sample with the German representative norming sample and carried out two separate regression analyses in order to determine which variables were associated with the two dimensions of patients' body image. Body image of individuals with Marfan syndrome appeared to be significantly impaired, with high percentile ranks for Negative Body Evaluation (women = 88, men = 91) and low percentile ranks for Vital Body Dynamics (women = 11, men = 4). Vital Body Dynamics was predicted by age (p = 0.016) and by depression (p less then 0.001), and Negative Body Evaluation was predicted by anxiety (p = 0.001). Body image in individuals with Marfan syndrome is not primarily determined by objective measures of fitness or by objective cardiac impairment but by psychological variables like depression and anxiety and by age. This finding can inform treatment and rehabilitation concepts. Accepting Marfan syndrome, including the acceptance of being visually different, may not only demand medical treatment and physical rehabilitation but also psychological treatment for depression and anxiety.Patients on dialysis are frequently administered high doses of potassium binders such as calcium polystyrene sulfonate (CPS) and sodium polystyrene sulfonate (SPS), which exacerbate constipation. Here, we compare the degree of constipation induced by CPS and SPS using a loperamide-induced constipation model to identify the safer potassium binder. Constipation model was created by twice-daily intraperitoneal administration (ip) of loperamide hydrochloride (Lop; 1 mg/kg body weight) in rats for 3 days. Rats were assigned to a control group, Lop group, Lop + CPS group or Lop + SPS group, and a crossover comparative study was performed. Defecation status (number of feces, feces wet weight, fecal water content and gastrointestinal transit time (GTT)) was evaluated. In the Lop + CPS group, GTT was significantly longer, and fecal water content was reduced. In the Lop + SPS group-although the fecal water content and GTT were unaffected-the number of fecal pellets and the fecal wet weight improved. Thus, SPS was less likely to cause constipation exacerbation than CPS.
