Analysis of Diagnostic Delay and its Impact on Lung Cancer Survival: Results From the Spanish Thoracic Tumor Registry.

Background: Early detection is crucial to improve lung cancer survival rates. Delays in diagnosis might negatively impact the prognosis of the disease. This study aims to analyze the diagnostic delay in lung cancer patients and describe if there is an association between delay and survival.

Comparative fecal steroid profile during pregnancy, parturition, and lactation between natural fertilization and embryo transfer in ocelots (Leopardus pardalis).

Despite the invaluable role that assisted reproduction technologies (ARTs) play in conservation, pregnancy and parturition rates by embryo transfer (ET) are low for most endangered felids. Thus, efforts to expand the knowledge on pregnancy biology and ET are still required. In this context, we examined fecal sex steroid metabolites (i.

Measuring psychosocial factors and predicting work ability among cemetery workers.

Background: The work of cemetery workers presents high physical demands and significant psychosocial stressors, but there are no studies about the influence of these risk factors on their work ability.

Objectives: The present study aims to analyse how socio-demographic and psychosocial factors are related to work ability among cemetery workers.

Methods: A cross-sectional survey was applied at seven cemeteries of Lisbon, between November and December of 2015.

Complicated intra-abdominal infections worldwide: the definitive data of the CIAOW Study.

The CIAOW study (Complicated intra-abdominal infections worldwide observational study) is a multicenter observational study underwent in 68 medical institutions worldwide during a six-month study period (October 2012-March 2013). The study included patients older than 18 years undergoing surgery or interventional drainage to address complicated intra-abdominal infections (IAIs). 1898 patients with a mean age of 51.

Utilisation of sperm-binding assay combined with computer-assisted sperm analysis to evaluate frozen-thawed bull semen.

Due to homologies between the chicken egg perivitelline membrane with mammalian zona pellucida proteins, spermatozoa of several species are able to bind to this membrane. However, adequate standardisation is required to attest possible applications of this technique for semen evaluation of a given species. Therefore, we thawed and divided cryopreserved semen samples into two aliquotes, one kept in water bath at 37 °C (thawed) and the other submitted to snap-freezing to damage sperm cells (dead spermatozoa).
