Objective: To determine the prevalence and profile of smoking among hospitalized patients at a university hospital in the south of Brazil. Methods: This was a descriptive cross-sectional study involving patients over 18 years of age hospitalized for over 24 h at the Federal University of Santa Catarina University Hospital, located in the city of Florianópolis, Brazil. The patients were interviewed on two distinct occasions. We collected demographic data, socioeconomic data, and data regarding smoking. Results: We interviewed 235 patients: 44 (18.7%) were smokers; 77 (32.8%) were former smokers; 114 (48.5%) were nonsmokers; and 109 (46.7%) were passive smokers. The mean age of the smokers was 45.7 ± 15.2 years, and 29 (65.9%) were male. Among the smokers, the median age at smoking initiation was 15 years; the mean smoking history was 32 ± 30.2 pack-years; 36 (81.9%) smoked up to 20 cigarettes/day; 20 (45.4%) had a high or very high degree of nicotine dependence; 32 (72.7%) had already tried to quit smoking; 39 (88.7%) would like to quit smoking; 32 (72.7%) would accept smoking cessation treatment; 13 (29.5%) smoked during hospitalization; and 13 (29.5%) suffered withdrawal syndrome. Regarding the motivation to quit smoking, the number of patients in the "preparation" and "action" stages of change increased from admission to discharge (from 31.8% to 54.8%). Conclusions: The prevalence of smoking in this study was similar to that reported in other studies conducted in Brazil. The results suggest that our sample was significant regarding the population of hospitalized smokers, who are motivated to quit smoking during hospitalization and require a systematized approach for doing so.

Objective: To determine the prevalence of and factors associated with smoking among medical students, as well as to evaluate the profile of this group. Methods: A total of 316 medical students (98.7% of the total) at the University of Passo Fundo, in the city of Passo Fundo, Brazil, completed a self-report questionnaire with questions on tobacco intake and on attitudes related to smoking. In accordance with the World Health Organization guidelines, the students were classified as daily smokers, occasional smokers, former smokers or nonsmokers, those in the two first categories being considered active smokers. Results: We found that 16.5% of the students were active smokers (daily smokers, 5.4%; occasional smokers, 11.1%) and that 3.5% were former smokers. The mean age was 22.2 ± 2.4 years. Factors significantly associated with the smoking habit (p < 0.05) were male gender, paternal smoking, regular alcohol consumption and use of antidepressants or anxiolytics. For the majority (69.2%) of the smokers, the age at smoking onset was 15-19 years of age, and the main motivations to start smoking were self-initiative and influence of friends. The conceptualization of smoking as an illness was significantly higher among the nonsmokers. In 70.6% of the smokers, tobacco intake was 1-10 cigarettes a day. Among the smokers, 92.3% agreed that smoking is harmful to health, 67.3% had tried to quit smoking, 96.0% believed themselves able to do so, and 87.2% intended to quit smoking. Conclusions: The prevalence of smoking remains significant among medical students. Therefore, it is fundamental that we develop more effective strategies for smoking prevention and cessation in order to reduce the number of smokers among future doctors.

Objective: To assess nicotine product use among incoming students at public and private universities in Brazil. Methods: This was a multicenter cross-sectional study including a convenience sample of incoming university students (= 18 years of age). Current use of conventional cigarettes, electronic cigarettes, and other nicotine products, as well as indicators of dependence and knowledge of the consequences of active use of or passive exposure to nicotine products were investigated with the use of a 38-item questionnaire. Descriptive statistics were used to analyze the data. Results: A total of 863 students completed the questionnaire. Of those, most (61%) were female, and most (76.6%) identified themselves as White. In addition, most (86%) were in the 18- to 24-year age bracket, and most (88.6%) attended a public university. In the past 30 days, 20.7% reported using electronic cigarettes, 23.2% reported using conventional cigarettes, and more than 50% reported using other nicotine products. More than 80% agreed that electronic cigarettes are harmful to health and are as damaging as other types of smoking. Over half of the respondents reported using the product shortly after waking up, and, paradoxically, 81% stated that they would quit whenever they wanted. Passive exposure was reported by 21.6%, occurring at home (in 33.6%), in other indoor environments (in 41.7%), and in open environments (in 87.5%). Conclusions: Experimentation and current use of nicotine products are high among incoming students at public and private universities in Brazil. Passive exposure to nicotine products is commonplace. Advanced communication tools are needed, particularly to emphasize the dangers of nicotine dependence. Being a legal drug, nicotine is often perceived as harmless, reinforcing the misconception that it can be used without consequences.

Objective: To determine the prevalence of smoking and to describe the profile and smoking habits of students attending the Universidade de Brasília (University of Brasília) in Brasília, Brazil. Methods: A total of 1341 students responded to a smoking questionnaire, adapted from the World Health Organization questionnaire, including questions directed at smokers, former smokers and nonsmokers. Twenty different courses in the areas of health, exact sciences and human sciences were evaluated. The students included in the study were duly enrolled in day courses and were evaluated during the second semester of 2003. Results: The overall prevalence of smoking was 14.7%. Approximately 80.8% of the students were nonsmokers, and 4.5% were former smokers. In the study sample, 57.3% of the students were male. No significant difference (p > 0.05) in the prevalence of smoking was observed in terms of gender or class year. The mean age of the study population was 21.6 ± 3.6 years, and the mean age at which the smoking habit was acquired was 17 ± 2.8 years. The percentage of smokers was higher in the Geology, Communication, and History courses (32.9, 26.3 and 24.4%, respectively). Mean consumption was 7.5 cigarettes per day. The majority (72.6%) of the students used commercial cigarettes rather than other types of tobacco. Conclusion: The high prevalence of smoking observed in the present study is similar to that reported for other universities and indicates the need for smoking control policies in university environments.

Objective: To evaluate the effectiveness of a smoking cessation program, delivered by trained health care professionals, in patients hospitalized for acute respiratory disease (RD) or heart disease (HD). Methods: Of a total of 393 patients evaluated, we included 227 (146 and 81 active smokers hospitalized for HD and RD, respectively). All participants received smoking cessation treatment during hospitalization and were followed in a cognitive-behavioral smoking cessation program for six months after hospital discharge. Results: There were significant differences between the HD group and the RD group regarding participation in the cognitive-behavioral program after hospital discharge (13.0% vs. 35.8%; p = 0.003); smoking cessation at the end of follow-up (29% vs. 31%; p < 0.001); and the use of nicotine replacement therapy (3.4% vs. 33.3%; p < 0.001). No differences were found between the HD group and the RD group regarding the use of bupropion (11.0% vs. 12.3%; p = 0.92). Varenicline was used by only 0.7% of the patients in the HD group. Conclusions: In our sample, smoking cessation rates at six months after hospital discharge were higher among the patients with RD than among those with HD, as were treatment adherence rates. The implementation of smoking cessation programs for hospitalized patients with different diseases, delivered by the health care teams that treat these patients, is necessary for greater effectiveness in smoking cessation.

Objective: To determine the prevalence of smoking and the frequency of smoking cessation counseling among patients at a university hospital, as well as to compare smokers and former smokers in terms of smoking history. Methods: A cross-sectional study involving 629 patients at the Federal University of Paraná Hospital de Clínicas, located in the city of Curitiba, Brazil. Results: Of the 629 patients, 206 (32.7%) were male, 76 (12.1%) were smokers, 179 (28.5%) were former smokers, and 374 (59.5%) were nonsmokers. The mean age of the patients was 49.9 ± 15.0 years (range, 18-84 years). Of the 76 smokers and 179 former smokers, 72 (94.7%) and 166 (92.7%), respectively, were questioned about tobacco use. Smoking history and degree of nicotine dependence were higher among the former smokers (p = 0.0292 and p = 0.0125, respectively). Gender, age at smoking initiation, physician inquiry about tobacco use, and smoking cessation counseling were comparable between the two groups. The smoking cessation rate was 0.70. The prevalence of heavy smoking varied by gender and by age bracket, being higher in males and in the 41-70 year age bracket. Conclusions: The smoking prevalence in this group of patients was lower than that reported for patients at another university hospital, for adults in Curitiba, and for adults in Brazil. The smoking cessation rate was higher in these patients than in the general population of Curitiba. Smokers and former smokers differed regarding age, smoking history, and degree of nicotine dependence. Heavy smoking and a moderate or high degree of nicotine dependence were not obstacles to smoking cessation.

Objective: To describe the epidemiological profile of tuberculosis cases reported among health care workers in the Tuberculosis Control Program of the Cassiano Antonio of Moraes University Hospital in Vitoria, Brazil. Methods: A retrospective descriptive study of secondary data was conducted between 2002 and 2006. Results: Twenty-five cases of health care workers with tuberculosis were reported: 8 in nursing technicians (32%); 4 in doctors (16%); 3 in nurses (12%); 2 in radiology technicians (8%) and 8 in professionals from other categories (32%). Of those 25 health care workers, 14 (56%) were male and 11 (44%) were female. The incidence of the disease was highest among those from 35 to 39 years of age. The predominant clinical presentation was extrapulmonary (12 cases, 48%), followed by pulmonary (11 cases, 44%) and a combination of the two (2 cases, 8%). Regarding comorbidities, AIDS, alcoholism and smoking, respectively, were present in 33.3% of the study population. Outcomes were as follows: 22 cases of cure (88%); 2 transfers (8%); and 1 death (4%). The proportion of health care workers diagnosed with tuberculosis in the period studied was 2.53%. Conclusions: The results show the need for heath care workers who work in the tuberculosis control program to fill out the field "professional occupation" on the tuberculosis case registry database reporting forms. In addition, this situation draws attention to the need to implement an occupational tuberculosis control program.

Despite the considerable efforts made in the fight against smoking in the last decades, there are still substantial numbers of people who, in full knowledge of the health hazards, begin smoking or continue smoking. Recent studies have focused on the genetic bases of the nicotine addiction. Various genetic polymorphisms have been associated with smoking. However, environmental factors have also been shown to play a role. In this review, we present some of the principal data collected in genetic studies of smoking behavior. The results obtained through this line of research will eventually aid clinicians in individualizing the type, dosage and duration of treatment for patients with nicotine dependence in accordance with the genotype of each smoker, thereby maximizing the efficacy of the proposed treatment regimen.

Objective: To determine the prevalence of ventilator-associated pneumonia in an intensive care unit, as well as to identify related factors and characterize patient evolution. Methods: This study evaluated 278 patients on mechanical ventilation for more than 24 hours in a university hospital. Results: Ventilator-associated pneumonia developed in 38.1% of the patients, translating to 35.7 cases/1000 ventilator-days: 45.3% were caused by gram-negative agents (Pseudomonas aeruginosa accounting for 22%); and multidrug resistant organisms were identified in 43.4%. In the ventilator-associated pneumonia group, time on mechanical ventilation, time to mechanical ventilation weaning, hospital stays and intensive care unit stays were all longer (p < 0.001). In addition, atelectasis, acute respiratory distress syndrome, pneumothorax, sinusitis, tracheobronchitis and infection with multidrug resistant organisms were more common in the ventilator-associated pneumonia group (p < 0.05). Mortality rates in the intensive care unit were comparable to those observed in the hospital infirmary. Associations between ventilator-associated pneumonia and various factors are expressed as odds ratios and 95% confidence intervals: acute sinusitis (38.8; 3.4-441); > 10 days on mechanical ventilation (7.7; 4.1-14.2); immunosuppression (4.3; 1.3-14.3); acute respiratory distress syndrome (3.5; 1.4-9.0); atelectasis (3.0; 1.2-7.3); cardiac arrest (0.18; 0.05-0.66); and upper gastrointestinal tract bleeding (0.07; 0.009-0.62). The variables found to be associated with in-hospital death were as follows: chronic renal failure (26.1; 1.9-350.7); previous intensive care unit admission (15.6; 1.6-152.0); simplified acute physiologic score II > 50 (11.9; 3.4-42.0); and age > 55 years (4.4; 1.6-12.3). Conclusion: Ventilator-associated pneumonia increased the time on mechanical ventilation and the number of complications, as well as the length of intensive care unit and hospital stays, but did not affect mortality rates.

Objective: To determine the epidemiological profile of inpatients at a TB referral hospital. Methods: This was a descriptive, retrospective study of the medical charts of patients with TB hospitalized at the Hospital Estadual Santa Maria (HESM), in the city of Rio de Janeiro, Brazil, between January of 2002 and December of 2003. Data were collected using a standardized form. Results: Of the 451 patients included in the study, 313 (69.4%) had been referred to the HESM from health care clinics, and 302 (67.0%) were male. Most of the patients were in the 30-59  year age bracket, 443 (98.2%) lived in the greater metropolitan region of Rio de Janeiro, and 298 (66.1%) lived in the city of Rio de Janeiro itself. The most common reason for hospitalization was poor health status (in 237, 52.5%). The most common comorbidity was AIDS (in 137, 30.4%). The most common signs and symptoms at admission were weight loss, fever and productive cough. Sputum smear microscopy was positive in 122 (71.0%) of the patients presenting with productive cough at admission. Of the 212 patients being retreated, 156 (73.6%) reported noncompliance with previous treatment. Regarding the outcome, 273 (65.8%) of the patients were referred to municipal health care centers, 83 (18.4%) died, 44 (9.8%) were cured, and 27 (6%) were discharged against medical advice. Conclusions: Providing hospitals specializing in TB is relevant for TB control, especially in metropolitan regions. In addition to taking biosafety measures, these hospitals must be prepared to treat patients with TB-related comorbidities and social problems. This study has resulted in improvements at the HESM.

In 2010, 96 patients suspected of being infected with the influenza A (H1N1) virus were hospitalized at the Hospital São Paulo, located in the city of São Paulo, Brazil. Of those 96 patients, 4 (4.2%) were found to be infected with influenza A virus-3 with influenza A (H1N1) and 1 with seasonal influenza A-and 2 patients (2.1%) were found to be infected with influenza B virus. Most (63.5%) of the suspected cases occurred in children, as did half of the positive cases. The second wave of influenza A (H1N1) infection was weaker in São Paulo. The decrease in the number of hospitalizations for H1N1 infection in 2010 might be attributable to vaccination.

Objective: To describe the clinical and therapeutic aspects of pulmonary tuberculosis and compare the adverse effects of the treatment and its outcome in elderly and nonelderly patients. Methods: This was a case-control study of 117 elderly individuals (over the age of 60 years) and 464 nonelderly individuals (aged 15-49 years). All subjects presented pulmonary tuberculosis that had been diagnosed and treated at the Thoracic Diseases Institute of the Federal University of Rio de Janeiro between 1980 and 1996. Results: In the elderly group, pulmonary tuberculosis was found to be correlated with diabetes (OR = 3.98; 95% CI = 2.07-7.65; p = 0.001), lung disease (OR = 7.24; 95% CI = 3.64‑14.46; p = 0.001) and heart disease (OR = 5.86; 95% CI = 2.88-11.95; p = 0.001). Smoking (OR = 2.07; 95% CI = 1.26‑3.42; p = 0.002) and alcohol abuse (OR = 1.63; 95% CI = 1.01-2.68; p = 0.041) were also more common in the elderly group. In the elderly group, the treatment more frequently resulted in adverse reactions (OR = 1.62; 95% CI = 1.04-2.54; p = 0.024), especially gastrointestinal reactions (OR = 1.64; 95% CI = 1.01-2.77; p = 0.047), and treatment efficacy was lower: cure rate, 51%; mortality rate, 24%. Treatment adherence was low (approximately 77%) in both groups. Conclusions: In the elderly group, adverse reactions were more common, treatment outcomes were less favorable, there was a greater frequency of clinical complications and deaths related to drug toxicity, and the prevalence of concomitant diseases was higher.

Introduction: Data on the relationship between personality profile and nicotine addiction may help health professionals in the design and improvement of programs for the treatment and prevention of addiction. Objective: To investigate the relationship between the personality profile and nicotine addiction in a group of smoking undergraduate students. Methods: A total of 1,245 undergraduate students were randomly selected among 10,500 students enrolled at the UFMT - Cuiabá campus in 2001. A standard questionnaire was applied for social characterization and to determine the pattern of cigarette consumption, with 80 students being considered smokers. These students were then submitted to the Fagerström Test (1978) of nicotine addiction and to the reduced version of the Comrey Personality Scale (CPS) which determines personality dimensions. Results: Analysis of the mean scores (Student t-test) revealed a marginal or inversely proportional borderline association between addiction and the Order x Lack of Compulsion scale (p = 0.06), and a negative or inversely proportional association between the CPS Extroversion x Introversion (p = 0.002) and Control of Validity scales (p = 0.04). Linear regression of the Fagerström Test points confirmed the inversely proportional borderline association between addiction and the Order x Lack of Compulsion (p = 0.06) and CPS Extroversion x Introversion scales (p = 0.02). However, controlling for interference of daily cigarette consumption, only the Extroversion x Introversion scale remained associated with addiction (p = 0.001). Conclusions: Smoker and nicotine dependent students are less extrovert than non-dependent smokers.

In 2005 and 2006, 8,121 clinical specimens submitted to the Mycobacteriology Laboratory of the Clementino Fraga Filho University Hospital/Thoracic Diseases Institute, in the city of Rio de Janeiro, Brazil, were inoculated on Löwenstein-Jensen medium containing glycerol and pyruvate. There were 79 mycobacteria isolates that presented growth only on pyruvate-containing medium, and those isolates were selected for the presumptive identification of Mycobacterium bovis. The selected isolates were screened with biochemical tests, PCR amplification (with the specific primers Rv0577 and Rv1510), and pyrazinamide susceptibility tests. All of the strains isolated showed specific phenotypical and genotypical patterns characteristic of M. tuberculosis, and no M. bovis strains were detected.

Objective: To determine the prevalence of smoking in the adult population of Brazil, in order to propose recommendations for the reduction of tobacco use. Methods: This was a population-based, cross-sectional study including a sample composed of residents (≥ 18 years of age) of the capital cities of 26 Brazilian states and in the Federal District of Brasília, Brazil. For the determination of sample size, a 95% confidence interval and a 2% sample error were defined. The participants were selected and interviewed by means of the Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL, Telephone-based System for the Surveillance of Risk and Protective Factors for Chronic Diseases).The proportion of smokers and the number of cigarettes smoked per day were estimated and stratified according to sociodemographic variables. In addition, the male/female ratio was estimated for the prevalence of smoking. Results: The prevalence of smoking was 16.1% (20.5% among males and 12.4% among females). The proportion of adults that reported smoking ≥ 20 cigarettes a day was 4.9%, being greater in males (6.5% vs. 3.6%). The prevalence of smoking was greater among individuals with a lower level of education (≤ 8 years of schooling). The number of cigarettes smoked per day by males was approximately the double that smoked by females. Conclusions: The VIGITEL estimates indicate a reduction in the prevalence of smoking, which was, however, still greater among males than among females. The VIGITEL has been fundamental to monitoring smoking, as well as to informing decisions regarding public policies for health promotion and the prevention of chronic nontransmissible diseases.

Objective: To analyze the prevalence of electronic cigarette (e-cigarette) awareness and experimentation among university students, as well as the characteristics associated with that awareness. Methods: This was a cross-sectional study, conducted in 2015, in which 489 university students at the Federal University of Mato Grosso (Cuiabá campus), Brazil, were interviewed with the use of a specific questionnaire. We estimated the prevalence of e-cigarette awareness and use, as well as analyzing the major characteristics associated with that awareness and use. Results: The prevalence of e-cigarette awareness was 37%, and the rate of e-cigarette experimentation was 2.7%. Awareness of e-cigarettes was found to be associated with marital status, work status, the level of parental education, and the presence or absence of smokers in the family. Conclusions: A high proportion of university students were aware of e-cigarettes. Although the prevalence of those who had experimented with e-cigarettes was low, there is concern that there could be an increase in the use of these types of device. There is a need for measures targeting university students, in order to build awareness of and prevent e-cigarette use.

Objective: To determine the prevalence and characteristics of smoking among inpatients at a university hospital, as well as to evaluate their motivation, interest, and need for help in quitting smoking. Methods: A prospective study involving inpatients treated between May of 2008 and April of 2009 on the cardiovascular disease wards at the Antonio Pedro University Hospital, located in the city of Niterói, Brazil. All inpatients were asked to complete a questionnaire designed to collect data regarding demographics, reasons for admission, and smoking status. The smokers also responded to additional questions regarding their smoking habits. The level of nicotine dependence was determined with the Fagerström Test for Nicotine Dependence. Results: Of the 136 inpatients who participated in the study, 68 (50.0%) were male. The mean age was 60.7 years. The prevalence of smoking was 13.2%. Among the 49 patients with coronary disease, 36 (73.5%) were smokers or former smokers. The majority of the patients presented with a high level of nicotine dependence and reported withdrawal symptoms during hospitalization. Although most smokers were motivated to quit smoking, they admitted that they needed help to do so. Conclusions: Because smoking is forbidden in the hospital environment and most inpatients who smoke are highly motivated to quit, health professionals should view the hospitalization period as an opportunity to promote smoking cessation.

This was a cross-sectional study aimed at determining the association between exposure to tobacco displays at the point of sale and susceptibility to smoking in schoolchildren in the 14- to 17-year age bracket. Of the participating students, 69.0%, 21.3%, and 9.7% were classified as never smokers, experimenters, and smokers, respectively. Of the participants who were classified as being exposed to smoking, 18.9% were susceptible to smoking. Of the participants who were classified as being unexposed to smoking, 12.9% were susceptible to smoking (OR = 1.56; 95% CI: 1.04 -2.35; p = 0.029). Exposure to point-of-sale tobacco displays is associated with smoking susceptibility in Brazilian adolescents.

Objective: To identify nontuberculous mycobacteria (NTM) isolated from sterile sites in patients hospitalized between 2001 and 2006 at the Clementino Fraga Filho University Hospital, located in the city of Rio de Janeiro, Brazil. Methods: During the study period, 34 NTM isolates from sterile sites of 14 patients, most of whom were HIV-positive, were submitted to phenotypic identification and hsp65 PCR-restriction enzyme analysis (PRA). Results: Most isolates were identified as Mycobacterium avium, followed by M. monacense, M. kansasii, and M. abscessus. Conclusions: The combination of PRA, a relatively simple and inexpensive method, with the evaluation of a few phenotypic characteristics can allow NTM to be accurately identified in the routine of clinical laboratories.

Background: Synergism between tuberculosis and HIV is responsible for the increased morbidity-mortality rate in AIDS patients. Objective: To delineate the profile of patients with tuberculosis and AIDS in the city of Rio Grande by relating demographic, clinical and laboratory data. Method: The sample comprised all cases of tuberculosis defined by identification of Mycobacterium tuberculosis that occurred in the AIDS Service of the University Hospital/FURG between September, 1997 and December, 2000, which added to a total of 31 patients confirmed as definite cases of AIDS. Using the Ogawa-Kudoh culture method and the Kinyoun bacilloscopy, 33 clinical pulmonary and extrapulmonary specimens were analyzed. Identification of M. tuberculosis was made by the usual phenotype methods. The method of proportions was chosen to establish resistance of isolated strains. Results: The mean age was of 33.8±9.9 years, with a man/woman ratio of 2.87:1 and 80.7% of Caucasians. All patients (n=31) exhibited overall or specific clinical manifestations of turberculosis at the time of suspicion diagnosis. In 20 of the cases risk factors were observed: use of injected drugs, alcoholism, malnutrition, imprisonment. Pulmonary disease occurred in 19 cases, extrapulmonary in 10 and the association of both in two. Lymph node commitment was more frequent among those with extrapulmonary disease. The isolated strains (33) were identified as M. tuberculosis and 28 were tested and showed sensibility to Isoniazid and Rifampin. Conclusion: In AIDS patients, tuberculosis appeared with various clinical manifestations, jeopardizing both men and women of less favored social conditions while at a fully productive stage of their lives.
