    Aim Squamous cell carcinoma antigen immune complexed with immunoglobulin M (SCCA-IgM) is a useful but not completely satisfactory biomarker of hepatocellular carcinoma (HCC). Considering its gender-specific behavior in preclinical models, we investigated gender-related differences of SCCA-IgM as a prognostic marker in HCC. Patients & methods Two hundred and eight prospectively recruited patients treated with transarterial chemoembolization in a single tertiary care hospital were retrospectively evaluated. Correlations between SCCA-IgM levels, clinical characteristics and survival were assessed according to gender. Results When the disease was advanced, SCCA-IgM was higher in males and lower in females. Levels below 130 AU/ml predicted a significantly longer survival in males (p = 0.007) and a shorter survival in females (p = 0.01). Conclusion In predicting the prognosis of HCC patients, the interpretation of SCCA-IgM should consider gender as a relevant variable.Aim NGAL, IL-18, KIM-1 as well as urinary TIMP2 and IGFBP7 and their mathematical product (TIMP2*IGFBP7) were evaluated for detecting pediatric aminoglycoside acute kidney injury (AG-AKI). Methods In a prospective study, noncritically ill children received aminoglycosides (AG) ≥3 days. The area under the curve (AUC) for biomarkers to detect AKI was calculated by a) days before AKI onset; b) treatment days. Results There were 113 AG episodes (68% febrile neutropenia). The AKI group had a higher proportion with febrile neutropenia. The AKI group had significantly lower NGAL 3 days before AKI, as patients with febrile neutropenia had a lower NGAL during AG treatment (p less then 0.05). NGAL, IL-18 and TIMP2*IGFBP7 had AUC ≥0.73 at 3, 2 and 2 days before AKI onset. Conclusion NGAL, IL-18 and TIMP2*IGFBP7 were modest early biomarkers of AG-AKI. Febrile neutropenia was associated with lower NGAL.

    Effective management of both acute and chronic bronchial infections is mandatory due to their high frequency rate, the relevant morbidity and mortality and the significant burden to health care systems, especially with the aging of population. Bacteria are the main causative pathogens, followed by viruses, and less commonly by fungi. The clinical evaluation of new therapeutic associations is mandatory to cope with the increases in resistance, in association with better infection control and antimicrobial policies.

    The authors searched Medline for any article published in English language up until March 1, 2020 that concerns the treatment of acute exacerbations and chronic infections in chronic obstructive respiratory disease and bronchiectasis.

    As acute exacerbations are a main common and detrimental event in patients with COPD and bronchiectasis, effective antimicrobial therapies and regimens should be optimized. The development of new molecules or combination regimens is vital to patients with severe and/or difficult-to-treat infections. Moreover, chronic infection control is mandatory in these patients to their improve quality of life, respiratory function and prognosis as well as for reducing health care costs.

Vascular insulin resistance, an increased insulin-stimulated endothelial production of ET-1 combined with impaired nitric oxide availability, is the hallmark of obesity-related vasculopathy, but dysregulated adipokine release from obese adipose tissue may contribute to the predominance of ET-1-dependent vasoconstriction. ET-1, in turn, might determine unhealthy obese adipose tissue expansion, with visceral and perivascular adipose tissue changes driving the release of inflammatory cytokines and atherogenic chemokines. In addition, ET-1 might also play a role in the development of the metabolic complications of obesity. Studies have shown inhibition of lipoprotein lipase activity by ET-1, with consequent hypertriglyceridemia. Also, ET-1 in pancreatic islets seems to contribute to beta cell dysfunction, hence affecting insulin production and development of diabetes. Moreover, ET-1 may play a role in nonalcoholic steatohepatitis. Recent clinical trials using innovative design have demonstrated that antagonism of ET-type A receptors protects against some complications of obesity and diabetes, such as nephropathy. These findings encourage further investigation to evaluate whether targeting the ET-1 system could afford better protection against other consequences of the obesity epidemic.Optimizing thawing conditions are required to maximize recovery of semen capacities after cryopreservation. This study aimed to assess the effect of thawing procedures on motility recovery and maintenance of semen capacities over time. A fractional factorial design approach was used to reduce the number of repetitions and simultaneously analyze the different interactions. Thirty canine frozen semen samples were thawed under different thawing conditions. Motility and velocity parameters were recorded using a computer-assisted semen analyzer up to 6 hours after thawing. Ten quadratic models were found to be significant, with the most significant effects observed on the velocity parameters. AS-703026 supplier Second, this study allowed us to evaluate the effect of the proAKAP4 marker on frozen/thawed semen, with regard to motility recovery. ProAKAP4 is the precursor of A-kinase anchor protein 4. It has been studied in several species as a marker to assess sperm quality. In our study, the expression of proAKAP4 was determined using flow cytometry.
