Urine osmolarity (OsmU) is the gold standard for the evaluation of the kidney's urine concentration capacity; nevertheless, urinary density (UD) is often used as a surrogate for its estimation. ⋯ The estimation of the OsmU from UD showed adequate performance. If an osmometer is unavailable, we recommend using the factor 35 for clean samples and 32 with adjusted UD for samples with proteinuria and/or glycosuria.

In colorectal cancer (CRC), regional lymphadenectomy provides prognostic information and guides management. The current consensus states that at least 12 lymph nodes (LN) should be evaluated. The aims of this study were to identify whether the number of LN is a predictor for survival and recurrence, and to reveal the role of LN ratio (LNR) and perineural invasion (PNI) in predicting prognosis after curative resection of CRC. ⋯ An LN retrieval < 10 increased local and distant recurrence rates. LNR was an independent prognostic factor for survival in Stage III tumors. PNI was the only significant independent prognostic factor affecting disease-free survival in our patients.

Pulmonary arterial hypertension (PAH) is a fatal complication in patients with connective tissue disease (CTD). ⋯ Patients with a partial response to the acute pulmonary vasodilator test with inhaled iloprost had a longer clinical deterioration-free period than non-responders.

Rheumatoid arthritis (RA) can affect the lungs in different manners, with interstitial lung disease (ILD) as the most serious manifestation. Although lung and joint compromise could be thought to evolve in parallel, there are data suggesting the opposite. In this study, we evaluated the relationship between lung and joint involvement in RA ILD. ⋯ We only found a good correlation between ESR and ground glass score. It is possible that different pathways of the immune response mediate damage in lungs and joints.

The use of single-photon emission computed tomography and positron emission tomography (PET) has proven to be helpful in differentiating Parkinson's disease (PD) from other movement disorders with a sensitivity of up to 95%. ⋯ The [11C]DTBZ PET has an excellent accuracy for differentiating idiopathic PD from other disorders.
