Community Health Agents (CHAs) play a crucial role in assisting the population. Due to the complexity of functions and situations to which they are exposed, they can present with emotional problems. The aim of this article was to verify the prevalence of anxiety symptoms and the association with sociodemographic and occupational factors in community health agents. It is a cross-sectional and populational study that used a questionnaire to collect data on the sociodemographic, economic and occupational conditions and the State Trait Anxiety Inventory (STAI). Descriptive analyses and multiple Poisson regression were performed with robust variation, considering a 5% significance level (p <0.05) for the final model. A total of 673 community health agents were evaluated. The prevalence of anxiety symptoms in the STAI-State was 47.4% and in the STAI-trait, 42.4%. The time working as a CHA longer than five years was associated with the STAI-state (p<0.001) and the STAI-trait (p=0.018), where as the female gender was associated with the STAI-trait (p=0.011). A high prevalence of anxiety symptoms in community health agents was verified. Health promotion strategies aimed at improving and monitoring the mental health of these workers by reducing anxiety disorders is required.

Purpose: To verify the prevalence of vocal complaints and their association with sociodemographic, economic, occupational, and behavioral factors among the population of Community Health Agents (CHA)., Methods: This is a cross-sectional and analytical study conducted in the city of Montes Claros, MG, in which 674 CHA participated. Data were collected via a self-administered questionnaire that includes sociodemographic, economic, behavioral, occupational, and voice-use aspects based on the Screening Index for Voice Disorder (SIVD). Bivariate analysis was performed by Pearson's chi-square test and Poisson multiple regression with robust variance to verify the association between the variables., Results: There was a high prevalence of vocal complaints, the most cited being dry throat, throat clearing, tiredness when talking, and hoarseness. We observed a significant association between female gender, lack of restful sleep, alcohol use, regular to very poor self-rated health, and anxiety., Conclusion: There was a significant percentage of vocal complaints, and the associated factors found will guide actions to promote vocal and general health.

Patients under treatment with oral anticoagulants present specific needs for which nursing care plays an important role, especially to prevent complications. The present review was carried out aiming at discussing nursing diagnoses for these patients by using the system of the North American Nursing Diagnoses Association--NANDA. Diagnoses for such patients depict the risk of bleeding and rethrombosis almost always due to the ineffective control of the therapeutic regimen and the deficit in the volume of fluids during active bleeding. Also, nursing interventions and assessment criteria are proposed for such conditions. The authors see the team's preparation to deal with such therapy as relevant for successful assistance.

In order to contribute to a better understanding of the possible role of hepatits B and C in the etiopathogenis of HCC in the East Amazon, there were studied 36 patients in Belém/PA. Serological hepatitis markers were evaluated and polymerase chain reaction assays were used to detect HBV-DNA and HCV-RNA. Alcohol abuse was observed in 33.3% and cirrhosis in 83.3%. In 88.9% of the sample, one or more hepatitis B markers were positive. Also, 8.3% those patients had anti-HCV simultaneously positive. The HBsAg serological test was positive in 58.3%; anti-HBc in 86%; anti-HBe in 85.7%; anti-HBe in 9.5%; IgM anti-HBc in 57.1%. The HBV DNA was found in 37.7% and in 65% of the HBsAg positive. The HCV RNA was detected in 8.5% and in 100% of the patients positive to anti-HCV. The AFP was above the normal value in 88.9% of patients, with levels up to 400ng/ml in 75% of them. In conclusion, hepatitis B virus infection seems to be important in the etiology of HCC and improving measures such immunization and screening in the risk population should be emphasyzed.

The Liver Diseases Program of the Hospital Santa Casa de Misericordia do Pará was create because of the need to attend patients with liver diseases of the Amazônia area, taking as priority to attend with quality, diagnosis of aetiologies, clinical following and specific treatment. This study aim to describe dates related to epidemiology, aetiologics agents and histopathologic analysis. One thousand sixty nine patients were evaluated through medical, laboratory, endoscopic, ultrasound or computerized tomography and histopathologic examination. Nine hundred thirty five (63.6%) patients within 1469 patients were diagnose as chronic liver disease. The average age was 50 year, 666 (71.2%) were male, and the most patients lived in Belem, State of Pará. The aetiologic agents most prevail were alcoholism (53.7%) and viral hepatitis (39.1%). Hepatic biopsy were done in 403 (43.1%) within the 935 patients and the results showed chronic hepatitis (34%) and chirrosis (34%). In summary the chronic liver disease in the amazon region is more prevail in male than female, the alcoholism is the principal aetiologie, and the most of these cases were diagnose in the severe phase.

Hepatitis B virus (HBV) infection presents itself with a variety of clinical manifestations. The present work aims to describe the prevalence of HBV genotypes and the occurrence of precore mutation A-1896 in a population group of the Eastern Amazon region of Brazil and to correlate them with the clinical presentation of chronic HBV infection. 51 HBsAg carriers (HBV-DNA positive) were selected and divided into three groups: A (14 asymptomatic subjects), B (20 HBeAg positive symptomatic patients) and C (17 HBeAg negative symptomatic patients). Using an automa ed DNA sequencer ABI model 377 by sequencing for determined of genotypes and precore mutation. The results showed that the genotype A was the most commonly found (81.1%, 89.5% and 93.7% in groups A, B and C, respectively) and precore mutation A-1896 was described in 11.5% (3/26) of group A subjects. Genotype A of HBV was the most prevalent (89.1%) and low occurrence of precore mutation A-1896, both not associate with the worst outcome of the chronic infection of HBV.
