Although serum ferritin (SF) has been shown in several studies to be a potential cancer biomarker, the results are inconsistent. Herein, a systematic review was performed to investigate the clinical SF levels in different types of tumors in order to verify the role of SF levels as a biomarker for cancer diagnosis. The search was performed using the PubMed/Medline, Cochrane Library, and Scopus databases. Observational studies comparing SF levels between healthy adults and patients with cancer were included. The meta-analysis was carried out according to the inverse variance and random effects model. The standardized mean differences (SMDs) were assessed at 95% confidence intervals (CIs). We found that SF was higher in patients with cancer (SMD 3.07; CI 1.96,4.17), especially for head and neck cancer (SMD 3.88; CI 0.42,7.34), lung cancer (SMD 1.72; CI 0.67,2.78), pancreatic cancer (SMD 6.79; CI 5.66,7.91), and renal cell carcinoma (SMD 1.77; CI 0.48,3.05). Moreover, in the advanced stages (Stages III and IV), ferritin levels were higher than in healthy adults (SMD 4.89; CI 2.72,7.06, and SMD 8.40; CI 6.99,9.82, respectively). SF acts as a biomarker for pancreatic cancer, renal cell carcinoma, lung cancer, and head and neck cancer and is a sensitive biomarker for the detection of advanced stages of tumors.

The aim of this study was to analyze the relationship between oral diseases and their impact on the daily performance of adult and elderly Brazilians, verify the association of oral diseases with socioeconomic and demographic features, and compare the standard estimate of need with the sociodental assessment of these same needs. The authors evaluated data from 17,398 Brazilians aged between 35-44 years and 65-74 years, taken from the cross-sectional Brazilian Oral Health Survey (Saúde Bucal Brasil - SBBrasil). Regression models were applied to assess associations among impacts on daily performance and income, schooling, gender, region, use of dental services, health perception and dental disease status. McNemar’s test was applied to compare standard versus impact-related estimates of need. The prevalence ratio of these impacts was associated with the sociodemographic versus health perceptions (p < 0.001) of adults and the elderly. Adults also had impacts associated with loss of periodontal attachment (p < 0.001). The prevalence of normative needs was 95.39% for adults and 99.76% for the elderly, whereas the impact-related estimate of need was 50.92% and 43.71%, respectively. The impacted-related approach had a statistically significant association with the normative estimate of need (p < 0.001). This study showed a relationship between oral impact on daily performance of adults and educational level. Sociodemographic features were also related to the impacts on both adults and the elderly, and to health perception. The impacts among the adults were related to the loss of periodontal attachment. In addition, the authors found a sizable difference between the standard versus the sociodental approach, in that the sociodental assessment needs were lower than the needs identified by the standard estimate of need.

Understanding facial trauma behaviors in different populations can help enhance effective prevention and efficient management of public resources in order to offer better treatment in large health systems. The aim of this study was to assess the epidemiology of maxillofacial trauma treated by a public health emergency care service. A cross-sectional study was conducted to assess maxillofacial trauma in patients treated by a public health service of emergency care at a midsize city in southern Brazil. Facial trauma records were retrieved directly from medical records from January 2010 to April 2014. The following variables were collected: patient age, sex, destination of patient after initial treatment, cause of trauma, and type of injury. Statistical analyses were performed using G tests with Williams' corrections (p < .05). The most frequent cause was road traffic collision (39.6%), followed by falls (33.6%) and interpersonal violence (22.0%). The prevalence of falls was higher in older adults. A statistically significant association was observed between age and causes (p < .05). After the initial care provided by the prehospital service, 44.1% of the patients were referred to secondary care centers and 40.1% to hospitals. Traffic accidents were the most common cause of facial trauma in Brazil, with a higher prevalence in young men. Falls were also a big concern for facial injuries, especially among older adults. Although most lesions could be classified as minor trauma, many patients are being treated at hospitals, which may increase the costs to the public health system.
