Prevalence of symptoms of COVID-19 in the state of Rio Grande do Sul: results of a population-based study with 18,000 participants.

Objective: To evaluate the prevalence of reports of symptoms of COVID-19 among individuals with and without antibodies and identify those with greater capability to predict the presence of antibodies against SARS-CoV-2.

Methods: The study uses data collected in phases 5 to 8 of Epicovid-19-RS. The presence of antibodies against SARS-CoV-2 was evaluated by a rapid test.

The cost of metastatic prostate cancer using time-driven activity-based costing.

Objective: To estimate the cost of metastatic prostate cancer (mPC) treatment using the time-driven activity-based costing (TDABC) method from the perspective of a philanthropic hospital in the Brazilian public health system (PHS) and to identify determinants of costs.

Methods: We used data from patients who received docetaxel chemotherapy in the Brazilian PHS from September 2012 to May 2017. Direct medical costs were estimated with the TDABC microcosting method, taking into account the multiple departments and services the patients interacted with during their oncological treatment.

Proportional weight loss in six months as a risk factor for mortality in stage IV non-small cell lung cancer.

Objective: To evaluate different weight loss (WL) cut-off points as prognostic markers of 3-month survival after diagnosis of stage IV non-small cell lung cancer (NSCLC).

Methods: This was a prospective study involving 104 patients with metastatic (stage IV) NSCLC who were admitted to a cancer treatment center in southern Brazil between January of 2014 and November of 2016. We evaluated total WL and WL per month, as well as WL and WL per month in the 6 months preceding the diagnosis.

Role of the Nurse Navigator: integrative review.

Objective: To identify scientific literature on oncology nurses who provide patient navigation services as nurse navigators.

Methods: Integrative review of literature searches in the databases LILACS, MEDLINE/PubMed, SCOPUS, SciELO, Web of Science and Science Direct based on the descriptors patient; navigation; nurse; professional; cancer; oncology; navigator; and navigators.

Results: Seventeen articles were identified and grouped according to the following thematic approach: Care Processes; Patients; and Health Workers.

The epidemiology of cancer in Angola-results from the cancer registry of the national oncology centre of Luanda, Angola.

Knowledge of the epidemiological profile of cancer is a key step in planning national cancer policy. The main objective of this study was to characterize the epidemiological profile of cancer in Angola based on cases of cancer registered at the National Oncology Centre (NOC) of Luanda, the only Angolan hospital to specialize in cancer treatment and diagnosis. The study consisted of a cross-sectional historical review of cases treated at the NOC between 2007 and 2011.

Early diagnosis of cutaneous melanoma: an observation in southern Brazil.

Background: The incidence of melanoma cutaneous and the mortalities rates are rising in most countries worldwide.

Objective: to describe the histopathological characteristics of cutaneous melanoma, according to the criteria established by the Brazilian Group of Melanoma, and to evaluate early diagnosis in a cancer treatment referral center.

Methods: we performed a cross-sectional descriptive study of cases of primary cutaneous melanoma identified after excisional biopsy and processed at the pathology laboratory of Complexo Hospitalar Santa Casa between Jan 1st 2000 and Jan 15th 2005.
