Subcutaneous dirofilariasis due to Dirofilaria immitis in a dog in Brazil: first report.

The aim of this study was to report on the presence of microfilariae of Dirofilaria immitis causing nodular pyogranulomatous dermatitis in a dog in the state of Rio Grande do Norte, northeastern Brazil. A 4-year-old male dachshund dog with lesions in the nostrils and left dorsolateral regions was treated. Tests were requested to aid in making the diagnosis, such as skin cytology, Knott's test, thick smear and histopathology of the lesions.

Decline in functional status after intensive care unit discharge is associated with ICU readmission: a prospective cohort study.

Objectives: To compare the functional status at intensive care unit (ICU) discharge of patients who were later readmitted to the ICU and patients discharged home and to verify whether a decline in functional status is associated with ICU readmission.

Design: Prospective cohort study.

Setting: ICU at a tertiary teaching hospital.

Relationship between availability of physiotherapy services and ICU costs.

Objective: To determine whether 24-h availability of physiotherapy services decreases ICU costs in comparison with the standard 12 h/day availability among patients admitted to the ICU for the first time.

Methods: This was an observational prevalence study involving 815 patients ≥ 18 years of age who had been on invasive mechanical ventilation (IMV) for ≥ 24 h and were discharged from an ICU to a ward at a tertiary teaching hospital in Brazil. The patients were divided into two groups according to h/day availability of physiotherapy services in the ICU: 24 h (PT-24; n = 332); and 12 h (PT-12; n = 483).

Assessing functional status after intensive care unit stay: the Barthel Index and the Katz Index.

Objective: To assess the functional status of post-ICU patients using the Barthel Index (BI) and the Katz Index (KI) and to assess which is more suitable for this population.

Design: Retrospective longitudinal study.

Setting: Public tertiary hospital in São Paulo (Brazil).

Recovery of functional capacity in severe trauma victims at one year after injury: association with trauma-related and hospital stay aspects.

[Purpose] The aim of this study was to investigate the functional capacity of trauma survivors one year after hospital discharge and to identify associations with trauma- and hospital stay-related aspects in a developing country. [Subjects and Methods] This study included severe trauma patients (Injury Severity Score ≥16; ≥18 years old) who were admitted to an intensive care unit in Sao Paulo, Brazil. Hospital stay data were collected from the patients' records.

Effects of non-aqueous fluids-associated drill cuttings discharge on shelf break macrobenthic communities in the Campos Basin, Brazil.

This paper assesses the effects of non-aqueous fluids (NAF)-associated drill cuttings discharge on shelf break macrobenthic communities in the Campos Basin, off the southeast Brazilian coast, Rio de Janeiro State. Samples were taken with a 0.25-m2 box corer from surrounding two oil and gas wells on three monitoring cruises: before drilling, three months after drilling, and 22 months after drilling.
