Comparison of morphometry and ventricular function of healthy and smoking young people.

BACKGROUND: Tobacco smoke is one of the most significant risk factors for cardiovascular diseases and damages in the myocardial tissue directly. Cardiac magnetic resonance (CMR) has been used and is a promising tool to evaluate morphometry and cardiac function in humans. The objective of this study was to evaluate associations of smoking with morphometry and cardiac function by CMR technique in young adult smokers. METHODS: Altogether, 49 volunteers (22 smokers and 27 non-smokers) were included in the study. The comparisons between groups were performed by multiple linear regression adjusting for body mass index and gender. RESULTS: In the morphometric and functional evaluation of the left ventricle, we observed statistical significant lower values of end-diastolic volume (EDV) (p = 0.02), ejection volume (EV) (p = 0.001) and indexed ejection volume (IEV) (p = 0.007) in smokers when compared to no-smoker group. Right ventricle showed statistical significant lower values of EDV (p = < 0.001), end-systolic volume (p = 0.01), EV (p = < 0.001), IEV (p = 0.001), indexed end-diastolic volume (p = 0.001) and major axis (p = 0.01) in smokers when compared to non-smokers group. CONCLUSIONS: There is a strongly association of smoking in young adult and cardiac function decline, even adjusted by cofounders, which compromises the proper functioning of the heart. Evidence confirms that smoking can directly influence the cardiac function, even without atherosclerosis or other chronic comorbidities, associated with increased risk of cardiovascular diseases.

Exploring the Psychosocial Impact of Wheelchair and Contextual Factors on Quality of Life of People with Neuromuscular Disorders.

Neuromuscular disorders (NMDs) are a group of heterogeneous diseases that show differences in incidence, hereditary, etiology, prognosis, or functional impairments. Wheelchair use (manual or powered) is influenced by several factors, including personal and contextual factors, and comprehensive evaluation of their impact is required in order to optimize prescription and provision of wheelchairs. The authors therefore assessed the influence of wheelchair use on the quality of life (QoL) of 60 participants with NMD using the Psychosocial Impact of Assistive Devices Scale (PIADS). The Functional Independence Measure (FIM) and a specially developed questionnaire were used to obtain information about contextual factors and participants' activity profile of activities of the participants. The results showed that using a wheelchair has psychosocial benefits, with the main determinants of benefit being type of wheelchair (powered), non-ambulation ability, and independence in mobility. Ensuring a good match between user and assistive technology (AT; e.g., wheelchair), as well as the effectiveness of the particular device, will increase the likelihood that the user will adopt it and use it effectively in daily life. Clinical prescription of AT would be improved by making appropriate use of outcome measures.

Physical Activity in Cerebral Palsy: A Current State Study.

This document analyzes a survey conducted in three geographical areas in Spain, focusing on centers for individuals with cerebral palsy (CP). The study aims to determine the adherence rate to recommended physical activity guidelines, assess if there is a decline in interest in physical activity over time, identify the stage at which this decline occurs, and explore potential mechanisms, tools, or strategies to sustain long-term engagement in regular physical activity for this population. The 36-item questionnaire comprises multiple-choice, open-ended, and Likert scale-type questions. Data were collected on physical activity frequency and duration, daily living activities, and demographics. Statistical analysis identified patterns and relationships between variables. Findings reveal that only a 17.6% meets the World Health Organization (WHO) recommendations regarding regular physical activity (RPA), decreasing in frequency or number of days a week, (3.7 d/w to 2.9 d/w; p < 0.01) and duration (50.5 min/d to 45.2 min/d; p < 0.001) with age, especially for those with higher Gross Motor Function Classification System (GMFCS) mobility levels. Obesity slightly correlates with session duration (ρ = -0.207; p < 0.05), not mobility limitations. Gender has no significant impact on mobility, communication, or physical activity, while age affects variables such as body mass index (BMI) and engagement (p < 0.01). A substantial proportion follows regular physical activities based on health professionals' advice, with interest decreasing with age. To improve adherence, focusing on sports-oriented goals, group sessions, and games is recommended. These findings emphasize the importance of personalized programs, particularly for older individuals and those with greater mobility limitations.

Learning About Assistive Technology from High School.

This communication will present an educative and research project that has linked the creation of 3D Assistive Technology (AT) for people with disabilities with the training of students of secondary education. STEMBach educational program aims to provide quality scientific education to secondary school students in the fields of science, technology, engineering, and mathematics (STEM) through research projects. Specifically, the text focuses on one project proposed by the TALIONIS research group, which uses 3D printers to design and create assistive technology (AT) for people with disabilities. The project involves students from eight different high schools and ten individuals with disabilities from four non-governmental organizations. The students design and print the AT using software such as Tinkercad and Cura Software. After testing the AT, outcome measurement instruments are used to validate their effectiveness. The project is based on a Learning-by-doing methodology with a structure of service-learning, and the involvement of the students is voluntary. The objectives of the project are to involve the students in research and innovation, to generate resources and AT for people with disabilities, and to determine the effects of AT on the lives of its users. Finally, the project leads to identifying new needs of people with disabilities that could be addressed through further research work.

Cardiac function, myocardial fat deposition, and lipid profile in young smokers: a cross-sectional study.

Background: There is a possibility that cardiac morphometric characteristics are associated with the lipid profile, that is, the composition and concentration of triglycerides, total cholesterol, HDL, LDL, and others lipoproteins in young smokers without comorbidities. Thus, this study aimed to evaluate the association of cardiac morphometric characteristics, myocardial fat deposition, and smoking cessation with the lipid profile of young smokers. Methods: A clinical and laboratory evaluation of lipids and the smoking status was performed on 57 individuals, including both a smoker group and a control group. Cardiac magnetic resonance imaging (MRI) with proton spectroscopy was performed to identify cardiac changes and triglyceride (TG) deposition in myocardial tissue. Results: No differences were observed between the groups (control vs. smokers) in relation to the amount of myocardial TG deposition (p = 0.47); however, when TG deposition was correlated with cardiac MRI variables, a positive correlation was identified between smoking history and myocardial TG deposition [hazard ratio (95% CI), 0.07 (0.03-0.12); p = 0.002]. Furthermore, it was observed that the smoking group had lower high-density lipoprotein cholesterol [51 (45.5-59.5) mg/dl vs. 43 (36-49.5) mg/dl, p = 0.003] and higher TG [73 (58-110) mg/dl vs. 122 (73.5-133) mg/dl, p = 0.01] and very-low-density lipoprotein cholesterol [14.6 (11.6-22.2) mg/dl vs. 24.4 (14.7-26.6) mg/dl, p = 0.01] values. In the control and smoking groups, a negative correlation between TGs and the diameter of the aortic root lumen and positive correlation with the thickness of the interventricular septum and end-diastolic volume (EDV) of both the right ventricle (RV) and left ventricle (LV) were noted. Moreover, in the RV, positive correlations with the end-systolic volume (ESV) index (ESVI), stroke volume (SV), ESV, and EDV were observed. Regarding serum free fatty acids, we found a negative correlation between their values and the diameter of the lumen of the ascending aortic vessel. Lipoprotein lipase showed a positive correlation with the SV index of the RV and negative correlation with the diameter of the lumen of the ascending aortic vessel. Conclusion: Several associations were observed regarding cardiac morphometric characteristics, myocardial fat deposition, and smoking cessation with the lipid profile of young smokers.

Cross-Cultural Validation of Quebec User Satisfaction with Assistive Technology 2.0 for Spanish Population (QUEST-2.0 ES).

BACKGROUND: Assistive technologies (ATs) are resources to promote the independence and participation of people with a disability. The use of standardized tools, based on outcome measures, is essential for guaranteeing high-quality rates. The Quebec User Evaluation of Satisfaction with AT-2.0 (QUEST) is a scale to assess the satisfaction of people using any AT. OBJECTIVES: To translate and culturally validate the QUEST-2.0 for the Spanish population (QUEST 2.0-ES). METHODS: A validation cross-design and descriptive study. The test-retest reliability, validity, and internal consistency of QUEST 2.0-ES were studied. It was divided into two phases: Sample 1 was formed by 26 persons; in sample 2, 30 persons participated. The conditions included neurological conditions, amputations, rare diseases, and deafness. RESULTS: Thirty-five men and 21 women participated in total. The majority of AT used were those for mobility. QUEST 2.0-ES analysis showed internal consistency values between the test (α = 0.87) and retest versions (α = 0.89). The internal consistency was high for AT (test, α = 0.83; retest, α = 0.87) and Service (test, α = 0.80; retest, α = 0.80). The temporal reliability (1-2 weeks) for test-retest was 0.88. CONCLUSION: QUEST 2.0-ES showed good psychometric properties in terms of validity and test-retest reliability, and it is a good tool to assess the user's satisfaction with ATs and services.

Assessment and counseling to get the best efficiency and effectiveness of the assistive technology (MATCH): Study protocol.

AIMS: To determine the psychosocial impact of assistive technology(AT) based on robotics and artificial intelligence in the life of people with disabilities. BACKGROUND: The best match between any person with disabilities and its AT only can be gotten through a complete assessment and monitoring of his/her needs, abilities, priorities, difficulties and limitations. Without this analysis, it's possible that the device won't meet the individual's expectations. Therefore, it is important that any project focused on the development of innovating AT for people with disabilities includes the perspective of outcome measures as an important phase of the research. In this sense, the integration of the assessment, implementation process and outcome measures is crucial to guarantee the transferability for the project findings and to get the perspective from the final user. METHODS: Pilot study, with prospective, longitudinal and analytical cohort. The study lasts from July 2020 until April 2023. The sample is formed by people with disabilities, ages from 2-21, that will participate from the first stage of the process (initial assessment of their abilities and needs) to the final application of outcome measures instruments (with a complete implication during the test of technology). DISCUSSION: Only with the active participation of the person is possible to carry out a user-centered approach. This fact will allow us to define and generate technological solutions that really adjust to the expectations, needs and priorities of the people with disabilities, avoiding the AT from being abandoned, with the consequent health and social spending.

Screening of microorganisms producing cold-active oxidoreductases to be applied in enantioselective alcohol oxidation. An Antarctic survey.

Several microorganisms were isolated from soil/sediment samples of Antarctic Peninsula. The enrichment technique using (RS)-1-(phenyl)ethanol as a carbon source allowed us to isolate 232 psychrophile/psychrotroph microorganisms. We also evaluated the enzyme activity (oxidoreductases) for enantioselective oxidation reactions, by using derivatives of (RS)-1-(phenyl)ethanol as substrates. Among the studied microorganisms, 15 psychrophile/psychrotroph strains contain oxidoreductases that catalyze the (S)-enantiomer oxidation from racemic alcohols to their corresponding ketones. Among the identified microorganisms, Flavobacterium sp. and Arthrobacter sp. showed excellent enzymatic activity. These new bacteria strains were selected for optimization study, in which the (RS)-1-(4-methyl-phenyl)ethanol oxidation was evaluated in several reaction conditions. From these studies, it was observed that Flavobacterium sp. has an excellent enzymatic activity at 10 °C and Arthrobacter sp. at 15 and 25 °C. We have also determined the growth curves of these bacteria, and both strains showed optimum growth at 25 °C, indicating that these bacteria are psychrotroph.

A Framework for a New Approach to Empower Users Through Low-Cost and Do-It-Yourself Assistive Technology.

BACKGROUND: Assistive Technology (AT) refers to "assistive products and related systems and services developed for people to maintain or improve functioning and thereby to promote well-being". Improving the process of design and creation of assistive products is an important step towards strengthening AT provision. PURPOSE: (1) to present a framework for designing and creating Low-Cost AT; (2) to display the preliminary results and evidence derived from applying the framework. METHODOLOGY: First, an evidence-based process was applied to develop and conceptualize the framework. Then, a pilot project to validate the framework was carried out. The sample was formed by 11 people with disabilities. The measure instruments were specific questionnaire, several forms of the Matching Person-Technology model, the Psychosocial Impact of Assistive Device Scale, and a tool to assess the usability and universal design of AT. RESULTS: The framework integrates three phases: Identification (Design), Creation (Making the prototype), and Implementation (Outcome Measures), based on the principles of Design Thinking, and with a user-centered perspective. The preliminary results showed the coherence of the entire process and its applicability. The matching between person and device was high, representing the importance of involving the user in the design and selection of AT. CONCLUSIONS: The framework is a guide for professionals and users to apply a Low-Cost and Do-It-Yourself perspective to the provision of AT. It highlights the importance of monitoring the entire procedure and measuring the effects, by applying the outcome measures.

A Study on Physical Exercise and General Mobility in People with Cerebral Palsy: Health through Costless Routines.

Sedentary behavior (SB) is a common problem that may produce health issues in people with cerebral palsy (CP). When added to a progressive reduction in motor functions over time, SB can lead to higher percentages of body fat, muscle stiffness and associated health issues in this population. Regular physical activity (RPA) may prevent the loss of motor skills and reduce health risks. In this work, we analyzed data collected from 40 people (20 children and teenagers, and 20 adults) who attend two specialist centers in Seville to obtain an up-to-date picture regarding the practice of RPA in people with CP. Roughly 60% of the participants showed mostly mid/severe mobility difficulties, while 38% also had communicative issues. Most of the participants performed light-intensity physical activity (PA) at least once or twice a week and, in the majority of cases, had a neutral or positive attitude to exercising. In the Asociación Sevillana de Parálisis Cerebral (ASPACE) sample test, the higher the International Classification of Functioning, Disability and Health (ICF), the higher the percentage of negative responses to doing exercise. Conversely, in the Centro Específico de Educación Especial Mercedes Sanromá (CEEEMS), people likes PA but slightly higher ratios of positive responses were found at Gross Motor Function Classification System (GMFCS) levels V and II, agreeing with the higher personal engagement of people at those levels. We have also performed a literature review regarding RPA in CP and the use of low-cost equipment. As a conclusion, we found that RPA produces enormous benefits for health and motor functions, whatever its intensity and duration. Costless activities such as walking, running or playing sports; exercises requiring low-cost equipment such as elastic bands, certain smartwatches or video-games; or therapies with animals, among many others, have all demonstrated their suitability for such a purpose.

Pressure-Induced Alopecia: Presence of Thin Hairs as a Trichoscopic Clue for the Diagnosis.

Pressure-induced alopecia (PA) is an unusual pattern of circumscribed hair loss that occurs after ischemic changes on the scalp. Trichoscopic findings described in the literature are scarce, nonspecific, and include black dots, broken hairs, circle hairs, and erythema. However, we report 3 cases of PA in which trichoscopy also showed many vellus and thin hairs. Possibly, the maintenance of these hair shafts may be explained by the more superficial insertion of their bulbs on the skin and/or their lower metabolic rates, making them suffer less from local hypoxia. Therefore, the authors suggest that these relevant signs should be added as a clue for the diagnosis of PA in doubtful cases.

Different Clusters in Patients with Chronic Obstructive Pulmonary Disease (COPD): A Two-Center Study in Brazil.

Background: Chronic obstructive pulmonary disease (COPD) has a functional definition. However, differences in clinical characteristics and systemic manifestations make COPD a heterogeneous disease and some manifestations have been associated with different risks of acute exacerbations, hospitalizations, and death. Objective: Therefore, the objective of the study was to evaluate possible clinical clusters in COPD at two study centers in Brazil and identify the associated exacerbation and mortality rate during 1 year of follow-up. Methods: We included patients with COPD and all underwent an evaluation composed of the Charlson Index, body mass index (BMI), current pharmacological treatment, smoking history (packs-year), history of exacerbations/hospitalizations in the last year, spirometry, six-minute walking test (6MWT), quality of life questionnaires, dyspnea, and hospital anxiety and depression scale. Blood samples were also collected for measurements of C-reactive protein (CRP), blood gases, laboratory analysis, and blood count. For the construction of the clusters, 13 continuous variables of clinical importance were considered: hematocrit, CRP, triglycerides, low density lipoprotein, absolute number of peripheral eosinophils, age, pulse oximetry, BMI, forced expiratory volume in the first second, dyspnea, 6MWD, total score of the Saint George Respiratory Questionnaire and packs-year of smoking. We used the Ward and K-means methods and determined the best silhouette value to identify similarities of individuals within the cluster (cohesion) in relation to the other clusters (separation). The number of clusters was determined by the heterogeneity values of the cluster, which in this case was determined as four clusters. Results: We evaluated 301 COPD patients and identified four different groups of COPD patients. The first cluster (203 patients) was characterized by fewer symptoms and lower functional severity of the disease, the second cluster by higher values of peripheral eosinophils, the third cluster by more systemic inflammation and the fourth cluster by greater obstructive severity and worse gas exchange. Cluster 2 had an average of 959±3 peripheral eosinophils, cluster 3 had a higher prevalence of nutritional depletion (46.1%), and cluster 4 had a higher BODE index. Regarding the associated comorbidities, we found that only obstructive sleep apnea syndrome and pulmonary thromboembolism were more prevalent in cluster 4. Almost 50% of all patients presented an exacerbation during 1 year of follow-up. However, it was higher in cluster 4, with 65% of all patients having at least one exacerbation. The mortality rate was statistically higher in cluster 4, with 26.9%, vs 9.6% in cluster 1. Conclusion: We could identify four clinical different clusters in these COPD populations, that were related to different clinical manifestations, comorbidities, exacerbation, and mortality rate. We also identified a specific cluster with higher values of peripheral eosinophils.

Assistive technology based on client-centered for occupational performance in neuromuscular conditions.

Knowledge of the patient's own perception of functioning and dependence, and of environmental factors, is of significant value. The main goals of this study are (1) to obtain a general profile of the occupational performance of persons with neuromuscular disorders (NMD) and their needs related to that performance and (2) to determine the support resources (assistive technologies [AT], adjustment, and/or caregiver) required to improve or maintain their level of independence.This cross-sectional study involved 24 persons with NMD. The functional independence measure (FIM), the checklist of a home's accessibility level, and a specific questionnaire were administered.The sample included 14 women (58.3%) and 10 men (41.7%). A mean of 61.7 (standard deviation = 17.2) was obtained for FIM motor, over 91, indicating a moderate level of dependence. The AT most frequently used was a wheelchair (70.8%). Architectural barriers were detected in the majority of users' homes (87.5%).Concise assessment of the independence needs of people with NMD, according to their occupational performance, and prescription of resources to meet those needs are required. This procedure should be implemented in healthcare programs, including care to a caregiver.

Geographic stomatitis: An enigmatic condition with multiple clinical presentations.

Geographic stomatitis is an uncommon inflammatory condition of unknown etiology. It is characterized by reddish areas surrounded by white borders affecting any location in the oral cavity and presenting a migratory and cyclic pattern. The most common affected sites include buccal mucosa, labial mucosa and mucobuccal fold. Some patients can complain of pain or burning sensation. There are few reports in the literature about this entity and its relationship with other oral and cutaneous conditions such as fissured tongue, Reiter's syndrome, atopy and psoriasis has been suggested but it is still controversial. In the present study we describe three cases of geographic stomatitis associated with fissured tongue. Lesions involved the buccal mucosa, labial mucosa, soft palate and mucobuccal fold and all cases were diagnosed based on their clinical features. All patients were oriented about the innocuous behavior of the condition and were advised to avoid exposure of the lesions to irritation factors. The three presented cases highlighted the importance of a detailed oral mucosal examination by clinicians and provided further information about the natural history and clinical presentation of geographic stomatitis. Key words:Geographic stomatitis, geographic mucositis, geographic tongue.

Evaluation of smoking cessation treatment initiated during hospitalization in patients with heart disease or respiratory disease.

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.

Smoking and Early COPD as Independent Predictors of Body Composition, Exercise Capacity, and Health Status.

The effects of tobacco smoke, mild/moderate COPD disease and their combined effect on health status (HS), body composition (BC), and exercise capacity (EC) impairment are still unclear. We hypothesized that smoking and early COPD have a joint negative influence on these outcomes. We evaluated 32 smokers (smoking history >10 pack/years), 32 mild/moderate COPD (current smokers or former smokers), and 32 never smokers. All individuals underwent medical and smoking status evaluations, pre and post-bronchodilator spirometry, BC [fat-free mass (FFM) and FFM index (FFMI)], EC [six-minute walk distance (6MWD)] and HS [Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36)]. FFM (p = 0.02) and FFMI (p = 0.008) were lower in COPD than never smokers. 6MWT, as a percentage of reference values for the Brazilian population, was lower in COPD and smokers than never smokers (p = 0.01). Smokers showed worse SF-36 score for functional capacity than never smokers (p<0.001). SF-36 score for physical functioning (p<0.001) and role-emotional (p<0.001) were impaired in COPD patients than smokers. SF-36 scores for physical functioning (p<0.001), role-physical (p = 0.01), bodily pain (p = 0.01), vitality (p = 0.04) and role-emotional (p<0.001) were lower in COPD than never smokers. Multiple linear regression analysis showed that both COPD diagnosis and smoking were inversely associated with FFMI, 6MWD and HS. Smoking and early COPD have a joint negative influence on body composition, exercise capacity and health status.

Prevalence of Bluetongue virus serotype 4 in cattle in the State of Sao Paulo, Brazil.

Bluetongue (BT) is considered endemic in several regions of Brazil. The State of Sao Paulo was divided into 7 cattle production regions (circuits) according the different systems of breeding, operational and logistical capacity of the state veterinary service. At least 1 animal from each property (a total of 1,716 farms) was tested by competitive ELISA for the presence of antibodies against BTV. Sero­positive sera were subsequently also tested by virus neutralization tests (VNT) using serial dilutions from 1:10 (cutoff) up to 1:640 (in MEM). BTV­4 neutralizing antibodies were detected in 86% (1,483/1,716) of the animals tested. These results show that BTV­4 is endemic and widespread in the State of San Paulo and indirectly confirm that in the State there are favourable conditions for the multiplication of competent vectors. However, as no clinical signs have ever been reported in cattle in the region, BTV­4 infection is likely to occur silently in the State of Sao Paulo.

Preventing smoking during pregnancy: the importance of maternal knowledge of the health hazards and of the treatment options available.

OBJECTIVE: To examine the pattern of tobacco use and knowledge about tobacco-related diseases, as well as to identify popular types of electronic media, in pregnant women, in order to improve strategies for the prevention or cessation of smoking among such women. METHODS: A cross-sectional study involving 61 pregnant women, seen at primary care clinics and at a university hospital, in the city of Botucatu, Brazil. For all subjects, we applied the Hospital Anxiety and Depression Scale. For subjects with a history of smoking, we also applied the Fagerström Test for Nicotine Dependence, and we evaluated the level of motivation to quit smoking among the current smokers. RESULTS: Of the 61 pregnant women evaluated, 25 (40.9%) were smokers (mean age, 26.4 ± 7.4 years), 24 (39.3%) were former smokers (26.4 ± 8.3 years), and 12 (19.8%) were never-smokers (25.1 ± 7.2 years). Thirty-nine women (63.9%) reported exposure to passive smoking. Of the 49 smokers/former smokers, 13 (26.5%) were aware of the pulmonary consequences of smoking; only 2 (4.1%) were aware of the cardiovascular risks; 23 (46.9%) believed that smoking does not harm the fetus or newborn infant; 21 (42.9%) drank alcohol during pregnancy; 18 (36.7%) reported increased cigarette consumption when drinking; 25 (51.0%) had smoked flavored cigarettes; and 12 (24.5%) had smoked a narghile. Among the 61 pregnant women evaluated, television was the most widely available and favorite form of electronic media (in 85.2%), as well as being the form most preferred (by 49.2%). CONCLUSIONS: Among pregnant women, active smoking, passive smoking, and alternative forms of tobacco consumption appear to be highly prevalent, and such women seem to possess little knowledge about the consequences of tobacco use. Educational programs that include information about the consequences of all forms of tobacco use, employing new and effective formats tailored to this particular population, should be developed, in order to promote smoking prevention and cessation among pregnant women. Further samples to explore regional and cultural adaptations should be evaluated.

Parenteral fish oil as a pharmacological agent to modulate post-operative immune response: a randomized, double-blind, and controlled clinical trial in patients with gastrointestinal cancer.

BACKGROUND: Fish oil-based lipid emulsions (FOLEs) have shown post-operative immunological and clinical benefits in parenteral nutrition. AIM: To assess post-operative immune response after short-term pre-operative parenteral infusion of isolated FOLE in gastrointestinal cancer patients. METHODS: The patients (n = 63) received pre-operative peripheral infusion (0.2 g fat/kg body weight/d) of FOLE (Omegaven(®)) or control lipid emulsion (MCT/LCT; Lipovenos MCT(®)) for 3 days. Post-operative concentrations of inflammatory mediators, leukocyte functions, surface molecules, infections, and length of intensive care unit (ICU) and hospital stay were measured. RESULTS: FOLE patients had a significant increase of IL-10 levels on day 3, decrease of IL-6 and IL-10 levels on day 6, lower decrease in leukocyte oxidative burst, maintenance of monocyte percentage expressing HLA-DR and CD32, and increase of CD32 neutrophil expression compared to MCT/LCT patients. No changes were observed in the frequency of post-operative infections or length of ICU and hospital stay. CONCLUSIONS: Short-term pre-operative infusion of FO alone improves the post-operative immune response of gastrointestinal cancer patients without significantly changing post-operative infections or length of ICU and hospital stay. ID:NCT01218841.

Evaluation of smoking cessation treatment initiated during hospitalization in patients with heart disease or respiratory disease / Avaliação de um tratamento para cessação do tabagismo iniciado durante a hospitalização em pacientes com doença cardíaca ou doença respiratória

ABSTRACT 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).

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.

RESUMO Objetivo: Avaliar a eficácia de um programa de cessação de tabagismo, oferecido por profissionais da saúde treinados, para pacientes hospitalizados por doença cardíaca (DC) ou doença respiratória (DR). Métodos: Foram avaliados 393 pacientes, sendo incluídos 227 (146 e 81 pacientes tabagistas ativos hospitalizados com DC e DR, respectivamente) que receberam intervenção para cessação tabágica durante a internação com seguimento de seis meses após a alta hospitalar. Resultados: Houve diferenças significativas entre os grupos DC e DR em relação à participação na intervenção cognitivo-comportamental após a alta hospitalar (13,0% vs. 35,8%; p = 0,003); cessação do tabagismo ao final do seguimento (29% vs. 31%; p < 0,001); e uso de terapia de reposição de nicotina (3,4% vs. 33,3%; p < 0,001). Em relação ao uso da bupropiona, não houve diferença entre os grupos DC e DR (11,0% vs. 12,3%; p = 0,92). A vareniclina foi usada em apenas 0,7% dos pacientes do grupo DC. Conclusões: Nesta amostra, os pacientes com DR apresentaram maior taxa de cessação tabágica após seis meses da alta hospitalar e maior adesão ao tratamento. A incorporação de programas de cessação do tabagismo para pacientes hospitalizados com patologias diversas, promovidos pelas equipes que os atendem, é necessária para que ocorra uma maior efetividade na cessação tabágica.
