Randomized Controlled Trial Comparative Study
Radioguided occult lesion localization versus wire-guided localization for non-palpable breast lesions: randomized controlled trial.
This prospective randomized clinical study was conducted to compare radioguided occult lesion localization (ROLL) with wire-guided localization to evaluate optimum localization techniques for non-palpable breast lesions. ⋯ The present study indicated that the ROLL technique is as effective as wire-guided localization for the excision of non-palpable breast lesions. In addition, ROLL improved the outcomes by reducing localization and operation time, preventing healthy tissue excision and achieving clearer margins.

Randomized Controlled Trial
Echocardiographic evaluation during weaning from mechanical ventilation.
Echocardiographic, electrocardiographic and other cardiorespiratory variables can change during weaning from mechanical ventilation. ⋯ No differences were observed between Doppler echocardiographic variables and electrocardiographic and other cardiorespiratory variables during pressure support ventilation and T-tube. However cardiac structures were smaller, isovolumetric relaxation time was larger, and oxygenation level was greater in successfully weaned patients.

Tinnitus is the perception of sound in the absence of an acoustic external stimulus. It affects 10-17% of the world's population and it a complex symptom with multiple causes, which is influenced by pathways other than the auditory one. ⋯ This specific subgroup -somatosensory tinnitus - is present in 65% of cases, even though it tends to be underdiagnosed. As a consequence, it is necessary to establish evaluation protocols and specific treatments focusing on both the auditory pathway and the musculoskeletal system.

Death at the beginning of life is tragic but not uncommon in neonatal intensive care units. In Portugal, few studies have examined the circumstances surrounding the final moments of neonates. We evaluated the care given to neonates and their families in terminal situations and the changes that had occurred one decade later. ⋯ Despite an increase in the withholding and withdrawing of therapeutic activities and improvements in pain management and family support, many neonates still receive curative and aggressive practices at the end of life.

The purpose was to assess functional (balance L-L and A-P displacement, sit-to-stand test (SST) and Tinetti scale - balance and gait) and neurophysiological aspects (patellar and Achilles reflex and strength) relating these responses to the BODE Index. ⋯ The individuals with COPD had functional and neurophysiological alterations in comparison with the control group. The BODE Index was correlated with the Tinetti scale and the SST. Both are functional tests, easy to administer, low cost and feasible, especially the SST. These results suggest a worse prognosis; however, more studies are needed to identify the causes of these changes and the repercussions that could result in their activities of daily living.
