Association between perceived stress and health-risk behaviours in workers.

Individuals who experience stress can engage in health-risk behaviours that may decrease work performance. The aim of this study was to determine perceived stress levels in Brazilian workers and verify whether perceived stress was associated with health-risk behaviours. Stress levels of 1,270 workers (1,019 men, 251 women) were assessed using the Perceived Stress Scale. The health-risk behaviours investigated were low intake of vegetables and fruits, daily smoking, high-risk alcohol consumption, physical inactivity, and the presence of obesity. The Student's t-test or one-way analysis of variance was used to assess differences in stress levels. Ordinal regression was used to determine the association between the degrees of stress and health-risk behaviours. Women had higher perceived stress levels than men. In addition, perceived stress levels were higher in those who had low socioeconomic status, were unmarried, had a negative perception of their health, were smokers, or had obesity. Smoking and the presence of two or more health-risk behaviours were associated with 1.84 (95% CI: 1.24-2.73) times and 1.49 (95% CI: 1.18-1.89) times higher odds of experiencing higher degrees of stress, respectively. In women, such an association was observed with the presence of obesity (odds ratio: 2.0; 95% CI: 1.01-3.98).

Peginterferon alfa-2a (40KD) (PEGASYS) plus ribavirin (COPEGUS) in retreatment of chronic hepatitis C patients, nonresponders and relapsers to previous conventional interferon plus ribavirin therapy.

Peginterferon alfa plus ribavirin is currently the treatment of choice for chronic hepatitis C. Peginterferon alfa-2a (40KD) plus ribavirin has given an overall sustained virological response of 18% in F3/F4 previous nonresponder US patients. We evaluated the effectiveness of peginterferon alfa-2a (40KD) plus ribavirin in Brazilian patients who were relapsers or nonresponders to previous interferon-based therapy. One-hundred-thirty-four patients with biopsy-proven chronic hepatitis C, HCV RNA positive, elevated ALT and who were either relapsers (n=37) or nonresponders (n=97) to at least 24 weeks of conventional interferon/ribavirin therapy were retreated with peginterferon alfa-2a (40KD) 180mg/qw and ribavirin 800 mg bid for 48 weeks. Efficacy was assessed as virological response (defined as undetectable HCV RNA) at the end of treatment (EoT) and at the end of follow-up (SVR - Sustained Virological Response). Safety assessments consisted of clinical and laboratory evaluations. In the patient sample, 72% were genotype 1 and 34% were cirrhotic. In an intention-to-treat analysis, relapser patients showed 78% EoT response and 51% SVR. Nonresponders showed 57% EoT response and 26% SVR. Positive predictive factors of SVR were non-1 genotype and relapser state. Six percent of the patients interrupted treatment because of adverse events and 45% had dose reduction (mainly associated with leucopenia and anemia). Brazilian patient relapsers and nonresponders to conventional interferon and ribavirin treatment can achieve a sustained virological response when retreated with peginterferon alfa-2a (40KD) and ribavirin. The safety profile is similar to that of naive patients.

[Psychiatric nursing and modern nursing in Rio de Janeiro: a history lesson]. / A enfermagem psiquiátrica e a enfermagem moderna no Rio de Janeiro: uma lição da história.

The present study is the result of an essay written for the discipline Research Laboratory of Nursing History. It refers to the interest and struggle of the Brazilian Association of Nursing (ABEN), in the 1940s, in Rio de Janeiro, to make professionals of this area aware of the need of the inclusion of nursing in the psychiatric field in Rio de Janeiro. Our objective is to present the difficulties of this insertion, although the beginnings and the regulation of the nursing profession in Brazil started in a school of nursing, in the Psychiatric Hospital of Rio de Janeiro. In order to present the difficulties for this inclusion, we analyzed the documents that prescribed the regulation of the nursing profession, in the psychiatric area of the hospital mentioned above. Results indicate that standards established by Anna Nery Nursing School were broken, since psychiatric assistance was denied by this school until 1949, while the Nursing School Alfredo Pinto provided this kind of care since 1890. It is important to point out the strategic and historical role of ABEn as the coordinator and motivator of discussions regarding the course of the nursing profession.

[Esophagus-enteric anastomosis ulceration caused by alendronate]. / Ulceração de anastomose esôfago-entérica causada por alendronato.

BACKGROUND: Alendronate sodium is an aminobisphosphonate indicated for the treatment of osteoporosis in post-menopausal women and has been associated with esophagitis in many reports. Esophageal stenosis, gastrointestinal symptoms as dyspepsia, nausea, vomiting and abdominal pain could be present. OBJECTIVE: Report a case of a patient who underwent total gastrectomy with Y-en-Roux anastomosis for a gastric carcinoid tumor and developed an esophagus-enteric anastomosis ulceration after the use of alendronate. PATIENT AND METHOD: A 63-year-old woman started medical therapy with alendronate in a dose of 10 mg daily. After a period of one month of medical treatment with this drug she began to complain of dysphagic symptoms and abdominal pain. She was submitted to endoscopic examination that showed an esophageal ulceration, an enteric ulceration of the anastomosis and an esophageal stenosis. RESULTS: Medical treatment with alendronate was discontinued and the symptom of abdominal pain disappeared. The intensity of dysphagia has decreased. The ulcerated lesion remitted although esophageal stenosis did not. The patient was subsequently treated with esophagus-enteric anastomosis dilation. She improved in her general state and nowadays she is free of symptoms. CONCLUSION: Alendronate sodium could cause lesions of the inferior esophageal portion or in distal segments of the gastrointestinal tube, in patients with a fast gastrointestinal transit. Special attention must be given to gastrectomized patients that use this drug because of the possibility to develop mucosal lesions in the enteric anastomosed part and its fearful complications as stenosis.

Phase II trial of paclitaxel and ifosfamide as a salvage treatment in metastatic breast cancer.

PURPOSE: Treatment results in patients failing first-line chemotherapy in metastatic breast cancer (MBC) are still unsatisfactory, with patients exhibiting poor responses to salvage therapy and a short overall survival. Both paclitaxel and ifosfamide are able to produce objective tumor responses in this disease. Therefore, the antitumor effects and toxicity of their combined use could be worthwhile studying in patients progressing after doxorubicin-containing combinations. PATIENTS AND METHODS: This Phase II trial of paclitaxel/ifosfamide included patients with bi-dimensionally measurable metastatic breast cancer in second or third relapse, following anthracycline-containing regimens; ECOG PS < 2, and adequate hepatic, cardiac, renal, and hematological functions. Paclitaxel 175 mg/m2 was given on day 1, in a 3-hour infusion with appropriate antiallergic pre-medication; while ifosfamide 1.8 g/m2 was given on days 2, 3, 4 with mesna 360 mg/m2 i.v., 15 minutes before and 4 hours after ifosfamide administration, and 720 mg/m2 P.O. 8 hours later at home, also on days 2, 3, 4. The cycles were repeated every 21 days, on an outpatient basis. RESULTS: Twenty-four patients were accrued for the study and 23 were considered eligible for the evaluation of toxicity and response. Previous chemotherapy included: CMF/FAC (16 cases); CMF plus mitoxantrone/FAC/cisplatin, vinblastine, mitomycin C (2 cases): and FAC/mitomycin C, vinblastine, and etoposide (5 cases). There were 11 (48%) objective responses (95% C.I.:27-69%), including 2 (9%) CR and 9 (39%) PR (95% C.I.:0-21% and 19-61%, respectively). Five (22%) patients attained disease stabilization. Median response duration was 7+ months (range 4 to 20+), and the median overall survival was 12 months (range 4-23+). The regimen was well tolerated. WHO nausea/ vomiting grades 1-2, alopecia grade 3, and neutropenia grades 1-2 were seen in most patients. Four patients experienced mild neuropathy, while it was grade 3 in 1 case. Seven patients had grade 3 neutropenia. In addition, grade 4 neutropenia associated with fever was documented in other 4 cases. No hypersensitivity reactions were seen. One case of reversible tachycardia after drug administration was seen. Myalgia grades 1-2 was also reported in some patients. CONCLUSION: These results suggest that the present regimen has significant activity in heavily pretreated patients with a MBC, with a manageable toxicity profile. Further trials exploiting the above mentioned drug combination are warranted.
