Bariatric Surgery and Vitamin D: Trends in Older Women and Association with Clinical Features and VDR Gene Polymorphisms

(1) Background: Obesity and its comorbidities can cause burdens and limitations. Bariatric surgery (BS) is indicated as a safe procedure to reduce body mass and improve present comorbidities. However, several complications were reported, such as vitamin D [25(OH)D] deficiency. We evaluated if 25(OH)D serum levels relate to clinical characteristics, symptoms, or habits in women after their BS, and whether the vitamin D receptor (VDR) gene's TaqI and FokI polymorphisms affected 25(OH)D levels and the total body bone mineral density (TBBMD). (2) Methods: This cohort cross-sectional comparative analytical prospective study consisted of 27 women, 61.6 ± 5.0 years, submitted to BS one year prior at a public reference hospital, DF-Brazil. All participants were asked to follow the physical and dietary activity recommendations and received vitamin D3 supplements. Their anthropometric, biochemical, and immunological measurements and blood samples were obtained. (3) Results: 73.3% of participants had low 25(OH)D levels, and their levels correlated positively with TBBMD and negatively with systolic pressure. VDR TaqI did not affect 25(OH)D levels, whereas VDR FokI's allele f presence correlated to a median rise in 25(OH)D levels. Neither polymorphism correlated to TBBMD. (4) Conclusions: 25(OH)D levels were positively correlated with TBBMD, negatively with systolic blood pressure, and were higher in those with the VDR FokI allele f.

An Assessment of Mortality among Elderly Brazilians from Alcohol Abuse Diseases: A Longitudinal Study from 1996 to 2019

Alcohol use disorder (AUD) is a worldwide public health problem, being an important aggravating factor of comorbidities found in the elderly, with the potential to increase mortality indicators for this age group.

OBJECTIVE

To analyze alcohol-induced deaths in elderly people with alcohol-related disorder in Brazil between 1996 and 2019.

METHODS

An ecological study was conducted with secondary data obtained from the Brazilian Unified Health System (SIM) Mortality Information System from 1996 to 2019. TabNet/DATASUS, Excel^® 2016 and SPSS 21^® were used to prepare the results.

RESULTS

Between 1996 and 2019, 85,928 alcohol-induced deaths were recorded among the elderly (>60 years); in 1996, the lowest number of deaths was recorded (n = 1396), and in 2018, there were the highest number of deaths (n = 5667). In the profile of the elderly, there was a predominance of men (88%). Mortality from AUD was due to alcoholic liver disease (62.2%), followed by mental disorders due to alcohol use (37.3%).

CONCLUSIONS

Coping with AUD is a public health problem that aims to reduce the number of deaths from diseases, conditions and injuries in which alcohol consumption is the causative agent, in addition to preventing deaths to which alcohol contributes.

THE EFFECT OF MUSCLE DAMAGE AND THE IL-6-174C/G POLYMORPHISM ON THE SERUM IL-6 LEVELS OF OLDER MEN

ABSTRACT Introduction Fast population aging is a global reality. Today’s major challenge is to promote the healthy aging of more and more people by acting on factors that can be modified, such as physical exercise. Regular exercise could contribute to the prevention of chronic diseases associated with aging. Research has been conducted on the physical training response of elderly individuals, but there is not yet any consensus on the influence of strength training or IL-6 polymorphism on levels of inflammatory markers such as IL-6 and muscle damage marker CK, particularly in healthy elderly male individuals. Objectives The aim of this study was to evaluate the relationship of IL-6 promoter -174 C/G gene polymorphism on systemic IL-6 responses and muscle damage after eccentric strength training in elderly men. Methods This is a prospective, high-quality study. Gene frequency of polymorphism of promoter gene IL6 G-174C was identified using the Hardy-Weinberg test in 28 older male volunteers. The relationships of each genotype with IL-6 and CK serum levels were analyzed. CK and IL-6 levels were determined at pre-training and 0h, 3h, 24h, and 48h post-training periods. Results Differences in baseline and post-training IL-6 levels of genotypic groups were observed for all time periods analyzed (p = 0.029). Eccentric exercise efficiently reduced post-intervention muscle damage, thus showing a statistical difference between the pre- and post-intervention time points ( p = <0.0005). Conclusion Eccentric training influenced CK and IL-6 modulation independently of the polymorphism of the IL-6 promoter gene -174 C/G. Level of evidence II, Prospective comparative type.

Access to medicines: relations with the institutionalization of pharmaceutical services

OBJETIVE

To analyze the relationship between access to medicines by the population and the institutionalization of pharmaceutical services in Brazilian primary health care.

METHODS

This study is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services 2015), a cross-sectional, exploratory, and evaluative study composed of an information survey in a representative sample of cities, stratified by Brazilian regions. Access was defined based on the acquisition of medicines reported by the patient, ranging between: total, partial, or null. The institutionalization of pharmaceutical services was analyzed based on information provided by pharmaceutical services providers and by those responsible for medicines delivery. Chi-square test and multinomial logistic regression were used in the statistical analysis.

RESULTS

Full access to medicines was greater when professionals affirmed there were the following aspects of the dimensions: "management tools," "participation and social control," "financing," and "personnel structure," with significant associations in the bivariate analysis. The "pharmaceutical care" dimension did not achieve such an association. After multinomial logistic regression, full access was more prevalent when those in charge of pharmaceutical services stated that: they always or repeatedly attend meetings of the Municipal Health Council, OR = 3.3 (95%CI 1.5-7.3); there are protocols for medicines delivery, OR = 2.7 (95%CI 1.2-6.1); there is computerized system for managing pharmaceutical services, OR = 3.9 (95%CI 1.9-8.0); those responsible for medicines delivery reported having participated in a course or training for professionals in the past two years, OR = 2.0 (95%CI 1.1-3.5); there is computerized system for pharmaceutical services management, OR = 4.3 (95%CI 2.4-7.5).

CONCLUSIONS

Aspects related to the institutionalization of pharmaceutical services have been strongly related to access to medicines. Our results indicate the need to prioritize its implementation, contributing to its consolidation in Brazil and to the effectiveness of health services regarding the purposes of pharmaceutical services policies.

Polypharmacy: a challenge for the primary health care of the Brazilian Unified Health System

OBJECTIVE

To characterize the polypharmacy in primary health care patients and to identify its associated factors.

METHODS

This is a cross-sectional, exploratory, and evaluative study, part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). The variable of interest was polypharmacy, defined as the use of five or more medicines. We sought to identify the association of sociodemographic variables and indicators of health conditions to polypharmacy. For group comparison, the Pearson's Chi-square test was used. The association between polypharmacy and explanatory variables was evaluated by logistic regression model (p < 0.05). The quality of the adjustment was verified by Hosmer-Lemeshow test.

RESULTS

The prevalence of polypharmacy among medicine users was 9.4% (95%CI 7.8-12.0) in the general population and 18.1% (95%CI 13.6-22.8) in older adults above 65 years old. We found statistically significant association between polypharmacy and age above 45 years, lower self-perception of health, presence of chronic diseases, having health insurance, care in emergency services, and region of the Country. South users presented the highest chances to polypharmacy. The most used medicines were those of the cardiovascular system, being compatible with the national epidemiological profile.

CONCLUSIONS

Polypharmacy is a reality in the population met within the primary care of Brazilian Unified Health System and may be related to excessive or inappropriate use of medicines. The main challenge to qualify health care is to ensure that prescription of multiple medicines be appropriate and safe.

Conceptions on pharmaceutical services in Brazilian primary health care

OBJECTIVE

To identify and discuss the conceptions of pharmaceutical services in Brazilian Primary Health Care, according to different subjects.

METHODS

This study is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015), which is composed of an information survey in a representative sample of cities, stratified according to Brazilian regions, and a subsample of primary health care services. Municipal secretaries of health, those responsible for pharmaceutical services, and those responsible for medicine delivery in pharmacies/dispensing units of the selected services were interviewed. The questionnaires included one question about the understanding of the interviewee regarding pharmaceutical services. The content analysis technique was used to apprehend, in the statements, the meanings attributed to pharmaceutical services, which were subsequently classified into categories according to their main conceptions.

RESULTS

Among the wide diversity of conceptions on pharmaceutical services (PS), we highlight the ones focused on 1) logistic control of medicines with activities concerning guidance or information on their use and 2) guidance or information to users on the use of medicine. The findings reveal a shifting tendency from a medicine-focused conception to one that considers the users and their needs as the final recipient of these actions. However, the lack of references to conceptions regarding care management and integrality point out the slowness of this change; after all, this is a social and historical process that comprises the production of meanings that transcend legal, logistic, and technical arrangements in pharmaceutical services.

CONCLUSIONS

The diversity of conceptions expresses the several meanings attributed to pharmaceutical services; we also identified, in their reorientation process, a movement that reflects a gradual shift in the technical paradigm, from the focus on medicine logistics to a user-oriented approach of health services.

Technical issues and conservation conditions of medicines in the primary health care of the Brazilian Unified Health System

OBJECTIVE

To characterize the technical issues and conditions of medicines conservation in Primary Health Care of Brazilian regions, responsible for pharmacy/dispensing unit profile; environmental, storage, and dose fractioning conditions; inventory control and waste management; fire and electrical failure safety items; transportation problems; advertising regulation; and pharmacovigilance.

METHODS

This article is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços (National Survey on Access, Use and Promotion of Rational Use of Medicines - Services)-, a cross-sectional and exploratory study, of evaluative nature, consisting of an information survey within a representative sample of municipalities, stratified by Brazilian regions, which constitute the study domains, and a sample of Primary Health Care services. Pharmaceutical services (PS) were directly observed with photographic record and face-to-face interviews with those responsible for the dispensing of medicines and over the telephone with those responsible for pharmaceutical services. Data were processed with the SPSS® software version 21.

RESULTS

The investigated dimensions showed relevant deficiencies and inequalities between the regions, generally more favorable in the Southeast and Midwest regions and weaker in the Northeast and North regions. We verified non-compliance with technical requirements and conditions essential to the conservation of medicines, which may interfere with the maintenance of stability and, thus, on their quality, efficacy, and safety. The regulation of advertising/promotion of medicines is still incipient and there is some progress in the structuring of mechanisms regarding pharmacovigilance.

CONCLUSIONS

The sanitary situation of medicines in Brazilian Primary Health Care is alarming due to the violation of the specific sanitary legislation for dispensing establishments and due to a wide range of requirements essential to the conservation of medicines. We observed a disconnection between the efforts made in the Brazilian Unified Health System to promote access to medicines for all population and the organization and qualification of pharmaceutical services.

Management of pharmaceutical services in the Brazilian primary health care

OBJECTIVE

To identify limiting factors in the management of pharmaceutical services in the primary health care provided by the Brazilian Unified Health System (SUS).

METHODS

This study was based on the data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), and it was conducted by interviews with professionals responsible for pharmaceutical services in Brazilian cities, in 2015. To identify the management limiting factors, we considered the organizational, operational, and sustainability indicators of the management. For the analyses, we included the weights and structure of analysis plan for complex samples. The results were expressed by frequencies and measures of central tendency with 95% confidence interval, considering the Brazilian geographic regions.

RESULTS

We identified the following limiting factors: lack of pharmaceutical services in the Municipal Health Secretariat organization chart (24%) and in the health plan (18%); lack of participation of managers in the Health Board and the absence of reference to this topic in the agenda of meetings (58.4%); lack of financial autonomy (61.5%) and lack of knowledge on the available values (81.7%); lack of adoption of operational procedures (about 50%) for selection, scheduling, and acquisition; and the fact that most professionals evaluate the organization of pharmaceutical services as good and great (58.8%), despite the worrisome indicators.

CONCLUSIONS

Pharmaceutical services management is currently supported by a legal and political framework that should guide and contribute to improve the pharmaceutical services in the Brazilian Unified Health System primary health care. However, there is a mismatch between the goals established by these guidelines and what is actually happening.

Characterization of the selection of medicines for the Brazilian primary health care

OBJECTIVE

To characterize the process of selection of medicines for primary health care in the Brazilian regions.

METHODS

This article is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015), a cross-sectional study that consisted of an information gathering in a sample of cities in the five regions of Brazil. The data used were collected by interviews with those responsible for pharmaceutical services (PS) (n = 506), professionals responsible for the dispensing of medicines (n = 1,139), and physicians (n = 1,558). To evaluate the difference between ratios, we adopted the Chi-square test for complex samples. The differences between the averages were analyzed in generalized linear models with F-test with Bonferroni correction for multiple comparisons. The analyses considered significant had p≤0.05.

RESULTS

The professionals responsible for pharmaceutical services reported non-existence of a formally constituted Pharmacy and Therapeutics Committee (PTC) (12.5%). They claimed to have an updated (80.4%) list of Essential Medicines (85.3%) and being active participants of this process (88.2%). However, in the perception of respondents, the list only partially (70.1%) meets the health demands. Of the interviewed professionals responsible for the dispensing of medicines, only 16.6% were pharmacists; even so, 47.8% reported to know the procedures to change the list. From the perspective of most of these professionals (70.9%), the list meets the health demands of the city. Among physicians, only 27.2% reported to know the procedures to change the list, but 76.5% would have some claim to change it. Most of them reported to base their claims in clinical experiences (80.0%). For 13.0% of them, the list meets the health demands.

CONCLUSIONS

As this is the first national survey of characterization of the process of selection of medicines within primary health care, it brings unpublished data for the assessment of policies related to medicines in Brazil.

Financing of Pharmaceutical Services in the municipal management of the Brazilian Unified Health System

OBJECTIVE

To discuss factors related to the financing of the Basic Component of Pharmaceutical Services within the municipal management of the Brazilian Unified Health System.

METHODS

The Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil - Serviços (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services) is a cross-sectional, exploratory, and evaluative study that performed an information survey in a representative sample, stratified by Brazilian regions It considered different study populations in the sampling plan, which represent primary health care services in the cities. Data were collected in 2015 by two methods: in person, by applying direct observation scripts and interviews with users, physicians, and professionals responsible for the dispensing of medicines in primary care services; by telephone interviews with municipal health managers and municipal professionals responsible for Pharmaceutical Services. The results were extracted from the questionnaires applied by telephone.

RESULTS

Of the sample of 600 eligible cities, we collected 369 interviews (61.5%) with secretaries and 507 (84.5%) with pharmaceutical services managers. 70.8% of the cities have a computerized management system; and 11.9% have qualification/training of professionals. More than half (51.3%) of the cities received funds for the structuring of pharmaceutical services, and almost 60% of these cities performed this type of spending. In 35.4% of cases, municipal secretaries of health said that they use resources of medicines from the Componente Básico da Assistência Farmacêutica (CBAF - Basic Component of Pharmaceutical Services) to cover demands of other medicines, but only 9.7% believed that these funds were sufficient to cover the demands. The existence of a permanent bidding committee exclusively for acquiring medicines was reported in 40.0% of the cities.

CONCLUSIONS

We found serious deficiencies in the public financing of medicines, as well as little concern about the formality in the use of public resources, expenses that meet individual demands to the detriment of the community, insufficient resources allocated to the Basic Component of Pharmaceutical Services, and exhaustion of the financing model.

Characterization of the institutionalization of pharmaceutical services in Brazilian primary health care

OBJECTIVE

To characterize the current stage of the institutionalization of pharmaceutical services in Brazilian cities.

METHODS

This study is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), a cross-sectional, exploratory, and evaluative study composed by an information survey in a representative sample of cities, stratified by Brazilian regions. We interviewed municipal secretaries of health, responsible for pharmaceutical services, and pharmacists responsible for the dispensing of medicines. The variables selected from the interviews were grouped into five dimensions that defined three stages of pharmaceutical services institutionalization: incipient (0%-34.0%), partial (35.0%-69.0%), and advanced (70.0%-100%), estimated based on the interviewees' answers. Frequencies were estimated with 95% confidence intervals. For the statistical association analysis, the Chi-square test was applied, with significance level of p<0.05.

RESULTS

Our results show a partial and heterogeneous process of institutionalization of pharmaceutical services in Brazil, and an advanced stage in formal structures, such as the municipal health plans and the existence of a standardized list of medicines. The analysed variables in the "organization, structure, and financing" dimension configured stages that range from partial to advanced. The management presented partial institutionalization, positively showing the existence of computerized system, but also disparate results regarding the autonomy in the management of financial resources. Indispensable items related to the structure expressed disparities between the regions, with statistically significant differences.

CONCLUSION

The study showed a partial and heterogeneous process of institutionalization of pharmaceutical services in Brazilian cities, showing regional disparities. Variables related to the normative aspects of institutionalization were positively highlighted in all dimensions; however, it is necessary to conduct new studies to evaluate the institutionalization of pharmaceutical services' finalistic activities.

Access to medicines by patients of the primary health care in the Brazilian Unified Health System

OBJECTIVE

To evaluate the access to medicines in primary health care of the Brazilian Unified Health System (SUS), from the patients’ perspective.

METHODS

This is a cross-sectional study that used data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Services, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines), conducted by interviews with 8,591 patients in cities of the five regions of Brazil. Evaluation of access to medicines used concepts proposed by Penshansky and Thomas (1981), according to the dimensions: availability, accessibility, accommodation, acceptability, and affordability. Each dimension was evaluated by its own indicators.

RESULTS

For the “availability” dimension, 59.8% of patients reported having full access to medicines, without significant difference between regions. For “accessibility,” 60% of patients declared that the basic health unit (UBS) was not far from their house, 83% said it was very easy/easy to get to the UBS, and most patients reported that they go walking (64.5%). For “accommodation,” UBS was evaluated as very good/good for the items “comfort” (74.2%) and “cleanliness” (90.9%), and 70.8% of patients reported that they do not wait to receive their medicines, although the average waiting time was 32.9 minutes. For “acceptability,” 93.1% of patients reported to be served with respect and courtesy by the staff of the dispensing units and 90.5% declared that the units’ service was very good/good. For “affordability,” 13% of patients reported not being able to buy something important to cover expenses with health problems, and 41.8% of participants pointed out the expense with medicines.

CONCLUSIONS

Results show 70%–90% compliance, which is compatible with developed countries. However, access to medicines remains a challenge, because it is still heavily compromised by the low availability of essential medicines in public health units, showing that it does not occur universally, equally, and decisively to the population.

Infrastructure of pharmacies of the primary health care in the Brazilian Unified Health System: Analysis of PNAUM - Services data

OBJECTIVE

To characterize the infrastructure of the primary health care pharmacies of the Brazilian Unified Health System, aiming at humanizing the offered services.

METHODS

This is a cross-sectional study, of quantitative approach, from data obtained in the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). Information on 1,175 pharmacies/dispensing units were gathered from direct observation and assessment of dispensing units installations conducted by trained researchers who used a standardized form. The analyzed variables refer to the physical structure of pharmacies or medicine dispensing units of the health units under research.

RESULTS

The pharmacy area was greater than 14 m2 in 40.3% of the sampled units, highlighting those from Midwest (56.9%) and Southeast (56.2%) regions and those of Northeast, with only 23.3%. About 80.2% units had waiting rooms with chairs for patients, 31.8% of them had dispensing areas inferior to 5m2, while in 46.2% these areas were superior to 10m2. Bars were found in service counters in 23.8% of health units, thus separating the patient from the professional; 44.1% had internet access. In most units, the area of medicine storage had no refrigerator or freezer for their exclusive storage and 13.7% had a specific room for pharmaceutical consultation.

CONCLUSION

Aiming at achieving care humanization and improving working conditions for professionals, the structuring of the environment of pharmacy services is necessary. This would contribute to the better qualification of pharmacy services, comprising more than medicine delivery. Data on the Northeast region indicated less favorable conditions to the development of adequate dispensing services. Based on the panorama pointed out, we suggest the expansion of stimulus concerning the physical structure of pharmaceutical services, considering regional specificities.

Main characteristics of patients of primary health care services in Brazil

OBJECTIVE

To characterize patients of primary health care services according to demographic and socioeconomic aspects, habits and lifestyle, health condition, and demand for health services and medicines.

METHODS

This study is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services), a cross-sectional study carried out between 2014 and 2015. Interviews were conducted with patients over the age of 17 years, with a standardized questionnaire, in primary health care services of a representative sample of cities, stratified by regions of Brazil. The analysis was performed for complex samples and weighted according to the population size of each region.

RESULTS

A total of 8,676 patients were interviewed, being 75.8% women, most of them aged from 18 to 39 years; 24.2% men, most of them aged from 40 to 59 years; 53.7% with elementary school; 50.5% reported to be of mixed race ethnicity, 39.7%, white, and 7.8%, black. Half of patients were classified as class C and 24.8% received the Bolsa Familia benefit. Only 9.8% had health insurance, with higher proportion in the South and lower in the North and Midwest. The proportion of men who consumed alcohol was higher than among women, as well as smokers. The self-assessment of health showed that 57% believed it to be very good or good, with lower proportion in the Northeast. The prevalence of chronic diseases/conditions, such as hypertension (38.6%), dyslipidemia (22.7%), arthritis/rheumatism (19.4%), depression (18.5%), diabetes (13.6%), and others are higher in these patients them among the general population. Medicines were predominantly sought in the health care service or in pharmacies of the Brazilian Unified Health System.

CONCLUSIONS

It was possible to characterize the profile of patients of Primary Health Care, but the originality of the research and its national scope hinders the comparison of results with official data or other articles.

Use of medicines by patients of the primary health care of the Brazilian Unified Health System

OBJECTIVE

To characterize the use of medicines by patients of the primary health care of the Brazilian Unified Health System (SUS).

METHODS

This is a cross-sectional, exploratory, and descriptive study, part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). Interviews were carried out with patients present in the services by semi-structured questionnaires. Sociodemographic, clinical, and use of medicines variables were assessed and the use of medicines in the 30 days prior to the interview was also verified. The population was stratified into three age groups: 18 to 44, 45 to 64, and 65 years or more. The differences between the age groups were verified using the Student’s t-test for continuous variables and chi-square test for the categorical ones. The complex samples analysis plan was employed. The medicines were classified according to the Anatomical Therapeutic Chemical Classification System.

RESULTS

Of the 8,803 patients interviewed, 6,511 (76.2%) reported to have used medicines in the 30 days prior to the interview. On average, each patient used 2.32 medicines, without difference between the sexes. Among medicine users, 18.2% were aged 65 years or more. Compared to the other age groups, older adults presented more comorbidities, used more medicines, and self-reported worse health conditions. They were also less educated, reported worse economic situation, and lived alone. The medicines that were mostly used were “other analgesics and antipyretics” (3^rd ATC level) and Losartan (5^th ATC level).

CONCLUSIONS

Most medicine users had lower education level and presented comorbidities. The most used medicines were the antihypertensive ones. Self-medication was higher among young people. Most patients reported to use generic medicines. The average number of medicines and the prevalence of use increased with age. Due to the characteristics observed and the difficulties in the use of medicines, older adults are in a situation of greater vulnerability.

Indicators related to the rational use of medicines and its associated factors

OBJECTIVE

To evaluate indicators related to the rational use of medicines and its associated factors in Basic Health Units.

METHOD

This is a cross-sectional study carried out in a representative sample of Brazilian cities included in the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos – Serviços, 2015 (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines – Services, 2015). The data were collected by interviews with users, medicine dispensing professionals, and prescribers; and described by prescription, dispensing, and health services indicators. We analyzed the association between human resources characteristics of pharmaceutical services and dispensing indicators.

RESULTS

At national level, the average number of medicines prescribed was 2.4. Among the users, 5.8% had antibiotic prescription, 74.8% received guidance on how to use the medicines at the pharmacy and, for 45.1% of users, all prescribed medicines were from the national list of essential medicines. All the indicators presented statistically significant differences between the regions of Brazil. The dispensing professionals that reported the presence of a pharmacist in the unit with a working load of 40 hours or more per week presented 1.82 more chance of transmitting information on the way of using the medicines in the dispensing process.

CONCLUSION

The analysis of prescription, dispensing, and health services indicators in the basic health units showed an unsatisfactory proportion of essential medicines prescription and limitations in the correct identification of the medicine, orientation to the patients on medicines, and availability of therapeutic protocols in the health services.

Medicine dispensing service in primary health care of SUS

OBJECTIVE

To characterize the medicine dispensing services in the primary health care network in Brazil and in its different regions, aiming to promote the access and rational use of medicines.

METHODS

This is a cross-sectional, quantitative study with data obtained from the Pesquisa Nacional sobre Acesso, Utilização e Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), 2015. Observation visits were carried out in 1,175 dispensing units, and interviews were held with 1,139 professionals responsible for the dispensation of medicines in the dispensing units and 495 municipal coordinators of pharmaceutical services.

RESULTS

More than half (53%) of the units presented a space smaller than 10 m2 for dispensing of medicines; 23.8% had bars or barriers between users and dispenser; 41.7% had computerized system; and 23.7% had counters for individual care. Among those responsible for dispensation, 87.4% said they always or repeatedly inform users how to use the medicines, and 18.1% reported developing some type of clinical activity. Isolated pharmacies presented a more developed physical and personal structure than those belonging to health units, but we found no significant differences regarding the information provided and the development of clinical activities.

CONCLUSIONS

There are major differences in the organization models of dispensation between cities, with regional differences regarding the physical structure and professionals involved. The centralization of medicine dispensing in pharmacies separated from the health services is associated with better structural and professional conditions, as in the dispensing units of the South, Southeast, and Midwest regions. However, the development of dispensation as health service does not prevail in any pharmacy or region of the Country yet.

Health-related quality of life of patients of Brazilian primary health care

OBJECTIVE

To analyze the Health-Related Quality of Life (HRQoL) of patients of the primary health care of the Brazilian Unified Health System (SUS) and its associated factors.

METHODS

This is a cross-sectional study with data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). Data were collected with a questionnaire that included the EuroQol 5 Dimensions (EQ-5D) instrument. Patients from the five regions of Brazil were interviewed. Multiple linear regression was used to analyze their Health-Related Quality of Life and its associated factors.

RESULTS

Of the total of 8,590 patients, the most frequent dimensions were pain/discomfort (50.7%) and anxiety/depression (38.8%). About 10% of the patients reported extreme problems in these dimensions. The following factors were significantly associated with a worse quality of life: being female; having arthritis, osteoarthritis, or rheumatism; cerebrovascular accident; heart disease; depression; health self-assessment as poor or very poor; drinking alcoholic beverages once or more per month; dieting to lose weight, avoiding salt consumption, and reducing fat intake. Significant association was observed between a better quality of life and: living in the North and Southeast regions of Brazil; practicing physical activities; and having a higher educational level. No association was observed with factors related to the health services.

CONCLUSIONS

The Health-Related Quality of Life of patients was influenced by demographic and socioeconomic factors that were related to health conditions and lifestyle, being useful to guide specific actions for promoting health and the integral care to patients of the Brazilian Unified Health System.

Patient satisfaction with pharmaceutical services in Brazilian primary health care

OBJECTIVE

To evaluate patient satisfaction with pharmaceutical services in Brazilian primary health care.

METHODS

This is a cross-sectional, exploratory, and evaluative study on a representative sample from the five Brazilian geopolitical regions resulting from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). The outcome was the patient's satisfaction, obtained using the item response theory. Associations were tested using Pearson's Chi-square test with sociodemographic and health variables, and multiple logistic regression analyses were carried out. The Hosmer-Lemeshow test was used to verify the adequacy of the final model. Logistic regression results were presented as odds ratio.

RESULTS

The overall percentage of patients satisfied with these services was 58.4% (95%CI 54.4-62.3). The "opportunity/convenience" aspect had the lowest satisfaction percentage (49.5%; 95%CI 46.4-52.6) and "interpersonal aspects," the highest percentage (90.5%; 95%CI 88.9-91.8), significantly higher than other aspects. Sex, age group, limitations due to disease, and self-perception of health remained associated in the final multiple logistic model regarding general satisfaction.

CONCLUSIONS

Most of the interviewed users were satisfied with pharmaceutical services in Brazilian cities, and the satisfaction with the customer's service was determinant in the patient's overall satisfaction.

Availability of essential medicines in primary health care of the Brazilian Unified Health System

OBJECTIVE

To characterize the availability of tracer medicines in pharmaceutical services in primary health care of the Brazilian Unified Health System (SUS).

METHODS

This is a cross-sectional and evaluative study, part of the Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). To analyze the availability of medicines, we verified 50 items selected from the Relação Nacional de Medicamentos Essenciais (Rename - National List of Essential Medicines) of 2012. Observation scripts were applied to medicine dispensing services in the primary health care. Interviews were carried out with patients, health care professionals, and public managers, using semi-structured questionnaires. The availability index was presented as the percentage of health units where the medicines were available. For statistical analysis, absolute, relative, and mean frequencies were presented (with 95% confidence intervals). The comparison of groups was carried out by Pearson Chi-square tests or variance analysis, when needed.

RESULTS

One thousand, one hundred, and seventy-five observation scripts were filled in a national representative sample composed by 273 cities. Statistically significant differences were observed regarding the type of unit, infrastructure, and presence of a pharmacist between regions of Brazil. The average availability of tracer medicines in primary health care was 52.9%, with differences between regions and sampling strata. This index increased to 62.5% when phytotherapic medicines were excluded. We found limited availability of medicines for treatment of chronic and epidemiological diseases, such as tuberculosis and congenital syphilis.

CONCLUSIONS

The low availability of essential medicines purchased centrally by the Brazilian Ministry of Health indicates deficiencies in supply chain management. The different views on the availability of tracer medicines in SUS confirm the general availability verified in this study. Among patients, about 60% said they obtain medicines in SUS units, data consistent with the lack of medicines reported by medicine dispensers and in line with physicians' evaluations.

Workforce in the pharmaceutical services of the primary health care of SUS, Brazil

OBJECTIVE

To characterize the workforce in the pharmaceutical services in the primary care of the Brazilian Unified Health System (SUS). METHODS This is a cross-sectional and quantitative study, with data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015). For the analysis, we considered the data stratification into geographical regions. We analyzed the data on workers in the municipal pharmaceutical services management and in the medicine dispensing units, according to the country's regions. For the statistical association analysis, we carried out a Pearson correlation test for the categorical variables.

RESULTS

We analyzed 1,175 pharmacies/dispensing units, 507 phone interviews (495 pharmaceutical services coordinators), and 1,139 professionals responsible for medicine delivery. The workforce in pharmaceutical services was mostly constituted by women, aged from 18 to 39 years, with higher education (90.7% in coordination and 45.5% in dispensing units), having permanent employment bonds (public tender), being for more than one year in the position or duty, and with weekly work hours above 30h, working both in municipal management and in medicine dispensing units. We observed regional differences in the workforce composition in dispensing units, with higher percentage of pharmacists in the Southeast and Midwest regions.

CONCLUSIONS

The professionalization of municipal management posts in primary health care is an achievement in the organization of the workforce in pharmaceutical services. However, significant deficiencies exist in the workforce composition in medicine dispensing units, which may compromise the medicine use quality and its results in population health.

National Survey on Access, Use and Promotion of Rational Use of Medicines: methods

The Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos -Serviços (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services) aimed to characterize the organization of pharmaceutical services in the Primary Health Care of the Brazilian Unified Health System (SUS). PNAUM - Services is a cross-sectional and evaluative study, with planned sample of 600 cities, held between 2014 and 2015, composed of a remote phase, with telephone interviews with health managers. Of these 600 cities, 300 were selected for a survey on health services. We selected the 27 capitals, the 0.5% largest cities of each region, and the remaining cities were drawn. The estimate of the representative national sample size considered three levels: cities, medicine dispensing services, and patients. The interviews were carried out with a structured questionnaire specific for: municipal secretaries of health, professionals responsible for pharmaceutical services in the city, professionals responsible for the dispensing of medicines, physicians, and patients. The secondary data were obtained in official databases, in the latest update date. PNAUM - Services was the first nationwide research aimed at the assessment and acquisition of national and regional indicators on access to medicines, as well as use and rational use, from the perspective of various social subjects.

Pharmaceutical care in Brazil's primary health care

OBJECTIVE

To characterize the activities of clinical nature developed by pharmacists in basic health units and their participation in educational activities aiming at health promotion.

METHODS

This article is part of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos - Serviços, 2015 (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines - Services, 2015), a cross-sectional and exploratory study, of evaluative nature, consisting of a survey of information in a representative sample of cities, stratified by the Brazilian regions that constitute domains of study, and a subsample of primary health care services. The interviewed pharmacists (n=285) were responsible for the delivery of medicines and were interviewed in person with the use of a script. The characterization of the activities of clinical nature was based on information from pharmacists who declared to perform them, and on participation in educational activities aiming at health promotion, according to information from all pharmacists. The results are presented in frequency and their 95% confidence intervals.

RESULTS

From the interviewed subjects, 21.3% said they perform activities of clinical nature. Of these, more than 80% considered them very important; the majority does not dispose of specific places to perform them, which hinders privacy and confidentiality in these activities. The main denominations were "pharmaceutical guidance" and "pharmaceutical care." The registration of activities is mainly made in the users' medical records, computerized system, and in a specific document filed at the pharmacy, impairing the circulation of information among professionals. Most pharmacists performed these activities mainly along with physicians and nurses; 24.7% rarely participated in meetings with the health team, and 19.7% have never participated.

CONCLUSIONS

Activities of clinical nature performed by pharmacists in Brazil are still incipient. The difficulties found point out to the professionals' improvisation and effort. The small participation in educational activities of health promotion indicates little integration of pharmacists with the health team and of pharmaceutical services with other health actions.

Cerebrospinal Fluid CRH Levels in Late Pregnancy Are Not Associated With New-Onset Postpartum Depressive Symptoms

CONTEXT

CRH participates in the hypothalamic-pituitary-adrenal axis and in neural circuits involved in the pathophysiology of depression. During pregnancy, the placenta produces large amounts of CRH, and production ceases abruptly after delivery. The relationship between CRH in the cerebrospinal fluid (CSF) during pregnancy and peripartum mood disorders has not been investigated.

OBJECTIVES

The objectives were to determine whether there are differences in CSF CRH concentrations of pregnant and nonpregnant women and whether CSF CRH concentrations in late pregnancy are associated with the presence of depressive symptoms during pregnancy and in the early postpartum period.

DESIGN

This was a prospective cohort study conducted from January to April, 2011.

SETTING

The study was conducted in one public and two private hospitals in Brasilia, Brazil.

PATIENTS

Patients included 107 healthy pregnant women who underwent elective cesarean delivery and 22 nonpregnant healthy women who underwent spinal anesthesia for elective surgical sterilization.

INTERVENTION

CRH in CSF was measured in pregnant and nonpregnant women by ELISA.

MAIN OUTCOME MEASURE

The association between CSF CRH concentration at delivery and maternal depression assessed before cesarean section and postpartum (4 to 8 wk) with the Edinburgh Postnatal Depression Scale (EPDS), with a cutoff of ≥ 13.

RESULTS

CRH concentration in the CSF was significantly higher in pregnant (4.1 ± 0.51 log CRH) than in nonpregnant women (3.6 ± 0.26 log CRH) (P < .001). Depressive symptoms starting after delivery occurred in 5.6% of women. CRH concentration in CSF was not different between women without depressive symptoms and women showing such symptoms during pregnancy or in the postpartum period.

CONCLUSION

CRH concentration in the CSF was higher in pregnant women than in nonpregnant women. However, in this sample, CSF CRH in late pregnancy was not associated with new-onset depressive symptoms in the early postpartum period.

Relações hipotéticas entre os determinantes sociais da saúde que influenciam na obesidade em idosos

Os elevados índices de prevalência de obesidade em idosos suscitam a necessidade de compreender os fatores envolvidos nesta desordem nutricional, por meio de métodos quantitativos que permitam uma análise relacional desses determinantes. O objetivo deste estudo foi propor um modelo hipotético que estabeleça as relações entre os determinantes sociais da saúde associados à obesidade em idosos. Para a construção do modelo hipotético, foram delineadas as variáveis latentes e observadas de acordo com a análise de 45 artigos nacionais e internacionais e em concordância com o referencial da Modelagem de Equações Estruturais. Foi construído um diagrama representativo para evidenciar as correlações entre os 11 determinantes sociais da saúde relacionados à obesidade no idoso: atividade física, tabagismo, etilismo, consumo alimentar, contato social, ocupação, renda, escolaridade, idade, sexo e estado civil. Espera-se que as relações hipotéticas estabelecidas no estudo contribuam para a compreensão das relações dos fatores que estão envolvidos nesse contexto visando ao desenvolvimento de estratégias para a saúde da pessoa idosa.

A influência da composição corporal na força de homens idosos brasileiros

INTRODUÇÃO: A população de idosos representa 10% do total da população brasileira. A diminuição da musculatura esquelética é provavelmente a alteração mais significativa, sendo associada à idade e algumas enfermidades, e é determinante na perda da força muscular. OBJETIVO: Avaliar a relação entre composição corporal e a força de preensão palmar de homens idosos brasileiros. MÉTODO: Quarenta e seis homens com idade igual ou superior a 60 anos foram divididos em 4 grupos de acordo com a percentagem de gordura e valor de massa magra. Foram definidas as medianas para %G = 28,65 e massa magra = 54,35 kg. Para as avaliações utilizou-se teste de bioimpedância elétrica e dinamômetro de preensão palmar. RESULTADOS: Observam-se diferenças significativas entre os quatro grupos quanto à massa magra e percentil de massa gorda (p≥0,05), caracterizando as especificidades de cada grupo quanto às variáveis analisadas. CONCLUSÃO: Os resultados demonstram que os níveis de força de preensão palmar não dependem unicamente da massa magra, mas também %G, em que a correlação entre massa magra e percentual de gordura pode indicar uma melhor ou pior condição para realizar o esforço isométrico de preensão manual.

Comparison of percentage body fat and body mass index for the prediction of inflammatory and atherogenic lipid risk profiles in elderly women

OBJECTIVE

To compare the clinical classification of the body mass index (BMI) and percentage body fat (PBF) for the prediction of inflammatory and atherogenic lipid profile risk in older women.

METHOD

Cross-sectional analytical study with 277 elderly women from a local community in the Federal District, Brazil. PBF and fat-free mass (FFM) were determined by dual energy X-ray absorptiometry. The investigated inflammatory parameters were interleukin 6 and C-reactive protein.

RESULTS

Twenty-five percent of the elderly women were classified as normal weight, 50% overweight, and 25% obese by the BMI. The obese group had higher levels of triglycerides and very low-density lipoproteins than did the normal weight group (P≤0.05) and lower levels of high-density lipoproteins (HDL) than did the overweight group (P≤0.05). According to the PBF, 49% of the elderly women were classified as eutrophic, 28% overweight, and 23% obese. In the binomial logistic regression analyses including age, FFM, and lipid profile, only FFM (odds ratio [OR]=0.809, 95% confidence interval [CI]: 0.739-0.886; P<0.0005) proved to be a predictor of reaching the eutrophic state by the BMI. When the cutoff points of PBF were used for the classification, FFM (OR=0.903, CI=0.884-0.965; P=0.003) and the total cholesterol/HDL ratio (OR=0.113, CI=0.023-0.546; P=0.007) proved to be predictors of reaching the eutrophic state.

CONCLUSION

Accurate identification of obesity, systemic inflammation, and atherogenic lipid profile is key to assessing the risk of cardiometabolic diseases. Classification based on dual energy X-ray absorptiometry measures, along with biochemical and inflammatory parameters, seems to have a great clinical importance, since it allows the lipid profile eutrophic distinction in elderly overweight women.

Elderly women with metabolic syndrome present higher cardiovascular risk and lower relative muscle strength

Objective:

To compare the metabolic, anthropometric, arterial blood pressure, and muscle strength parameters of elderly women with and without metabolic syndrome.

Methods:

A case-control study with 27 (67.3±4.8 years of age, 31.0±5.0kg/m²) elderly women with metabolic syndrome and 33 (68.8±5.6 years of age, 27.2±5.3kg/m²) sedentary control elderly women. They were submitted to an evaluation of body composition by means of dual-energy X-ray absorptiometry and muscle strength testing with 10 maximal repetitions of knee extension.

Results:

When compared to the elderly women without metabolic syndrome, those with the metabolic syndrome had higher levels for body mass (72.2±13.5 versus 63.4±14.6kg, p=0.03), body mass index (31.0±5.0 versus 27.2±5.3kg/m^2, p=0.007), fat mass (30.9±9.9 versus 24.4±8.5kg, p=0.01), systolic arterial pressure (125.1±8.2 versus 119.3±8.7mmHg, p=0.01), diastolic arterial pressure (75.5±6.9 versus 71.4±6.7mmHg, p=0.03), mean arterial pressure (92.5±6.2 versus 87.1±6.7mmHg, p=0.004), blood glucose (103.8±19.1 versus 91.1±5.9mg/dL, p=0.001), triglycerides (187.1±70.2 versus 116.3±36.7mg/dL, p=0.001), and creatine kinase (122.6±58.6 versus 89.8±32.5U/L, p=0.01); lower levels were found for fat-free mass (55.9±5.8 versus 59.3±6.7%; p=0.05), HDL-C (40.7±5.0 versus 50.5±10.1mg/dL, p=0.001), and relative muscle strength (0.53±0.14 versus 0.62±0.12, p=0.01).

Conclusion:

Elderly women with metabolic syndrome have a higher cardiovascular risk and less relative muscle strength when compared to those without metabolic syndrome. Relative muscle strength may be related to the cardiovascularr risk factors of the metabolic syndrome.

Effects of a recreational physical activity and healthy habits orientation program, using an illustrated diary, on the cardiovascular risk profile of overweight and obese schoolchildren: a pilot study in a public school in Brasilia, Federal District, Brazil

INTRODUCTION

Educative strategies need to be adopted to encourage the consumption of healthy foods and to promote physical activity in childhood and adolescence. The effects of recreational physical activity and a health-habit orientation program using an illustrated diary on the cardiovascular risk profile of overweight and obese children was investigated.

METHODS

The weight and height of 314 schoolchildren aged between 9 and 11 years old, in a public school in Brasilia, Federal District, Brazil, were recorded. According to the body mass index (BMI) classification proposed by the World Health Organization, 84 were overweight or obese for their age and sex. Of these children, 34 (40%) participated in the study. Students were divided into two groups matched for sex, age, BMI, percent body fat (%BF): the intervention group (IG, n = 17) and the control group (CG, n = 17). The IG underwent a program of 10 weeks of exercise with recreational activities and health-habit orientation using an illustrated diary of habits, while no such interventions were used with the CG during the study period. Before and after the intervention, the children's weight, height, BMI, %BF, waist circumference (WC), maximum oxygen intake (VO2max), total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides, glucose, eating habits, and physical activity level (PAL) were assessed. In analyzing the data, we used descriptive statistics and paired and unpaired t-tests, using a significance level of 0.05. For assessment of dietary habits, a questionnaire, contingency tables, and the chi-squared test were used, with <0.05 set as the significance level.

RESULTS

After 10 weeks of intervention, the IG showed a reduction in BMI (pre: 22.2 ± 2.1 kg/m(2) versus [vs] post: 21.6 ± 2.1 kg/m(2), P < 0.01); WC (pre: 70.1 ± 6.1 cm vs post: 69.1 ± 5.8 cm, P < 0.01); %BF (pre: 29.2% ± 4.6% vs post: 28.0% ± 4.8%, P < 0.01); systolic blood pressure (P < 0.01); VO2max (P = 0.014); TC (P < 0.01); LDL (P < 0.01); triglycerides (P < 0.01); and intake of candy (P < 0.01) and soda drinks (P < 0.01), while an increase in the consumption of fruit (P < 0.01) and PAL (P < 0.01) were observed. The CG did not show any change in the health parameters assessed.

CONCLUSION

The program was effective in reducing risk factors for cardiovascular disease and the use of an illustrative diary may have been the key to this result, since students were motivated to change their poor eating habits and to increase their physical activity level.

Intervenção interdisciplinar enquanto estratégia para o Uso Racional de Medicamentos em idosos

A presente pesquisa avaliou a efetividade de intervenções interdisciplinares, envolvendo médicos, farmacêuticos e nutricionistas, destinadas à promoção do Uso Racional dos Medicamentos. Trata-se de um estudo de caráter prospectivo e analítico, com uma população de mulheres idosas, onde a efetividade da intervenção foi avaliada de acordo com indicadores de Uso Racional dos Medicamentos preconizados pela Organização Mundial de Saúde. As análises estatísticas foram realizadas utilizando-se do teste t ou one-way ANOVA para variáveis discretas, e o teste de qui-quadrado para avaliação categórica das variáveis. Após a intervenção, houve uma redução média no consumo de medicamentos em relação às consultas da pré-intervenção (p=0,001). Os medicamentos utilizados na terapêutica cardiovascular foram os mais consumidos, o que se encontra em consonância com as doenças autoreferidas pelas idosas. Foi possível verificar que a intervenção interdisciplinar em idosas pôde contribuir para melhoria dos indicadores de Uso Racional dos Medicamentos, em especial os de prescrição.

Cost of antimicrobial treatment of patients infected with multidrug-resistant organisms in the Intensive Care Unit

This study aims to compare the costs of antimicrobial drugs used in the treatment of patients infected with multidrug-resistant organisms (MDRO) or those not infected with this type of organisms in an intensive care unit (ICU). It is a retrospective comparative case-control study, performed in a public hospital in the capital city of Brazil, comprising the years 2007, 2008 and 2009. Information on age, sex, length of hospitalization, clinical outcome, antimicrobial drugs, microorganisms and microbial sensitivity to antibiotics was collected. Spearman and Mann-Whitney tests were used for statistical analysis. The level of significance was set at p < 0.05. The sample consisted of 401 patients with a mean age of 51.36 years (± 19.68) being 226 (56.4%) male. As for the length of stay, 32.9% of the patients remained more than 20 days, with 195 discharged and 206 deaths. Global cost of antimicrobial treatment was US$ 1113 221.55 during the three year period. Treatment cost for patients with MDRO was higher than for those without (p = 0.010). At least one MDR strain was isolated in 54.6% of the patients. According to these results, nosocomial infections due to MDRO and the high costs involved may endanger the effectiveness of antimicrobial therapy in ICU and Health Centers.

Does the Agaricus blazei Murill mushroom have properties that affect the immune system? An integrative review

There has been a significant increase in the use of mushrooms for therapeutic and medicinal purposes, in particular, use of the species Agaricus blazei Murrill, a basidiomycota of Brazilian origin. The objective of this study was to identify scientific evidence regarding the influence of A. blazei Murrill on the immune system. We undertook an integrative review of indexed publications published between 2000 and 2009, using the following question as a guideline: "What evidence can be found in the literature regarding the influence of A. blazei Murrill on the immune system?" Fourteen studies verified that there is in vitro and in vivo research demonstrating this mushroom's influence on the immune system. All research was characterized as evidence level 7 (preclinical study [animals/in vitro]). The research shows that A. blazei Murrill functions through bioactive compounds via mechanisms that are not yet entirely clear, although it has been shown that they promote action on the innate and adaptive immunological response, activation of the complement system, and synthesis of pro- and anti-inflammatory cytokines and even aid in diapedesis. Despite broad scientific evidence demonstrating relevant immunomodulatory properties of A. blazei Murrill, randomized clinical trials with human subjects are still needed in order for the mushroom to be put into clinical practice.

[Albumin and drug therapy in the prognosis of hospitalized elderly]

OBJECTIVE

This study aimed to investigate the relationship between serum albumin levels, drugs used, length of hospitalization and number of diseases with the prognosis of hospitalized elderly.

METHODS

A descriptive cross-sectional and retrospective study was carried out using a review of medical charts. Variables collected were disease motivating admission, albumin, drugs used and their affinity for albumin and length of stay in an elderly population of a Brazilian public hospital. We used multiple regression to assess whether age, length of stay, medication with or without affinity to albumin and number of drugs motivating admission were causes of death. The relation between dependent and independent variables was analyzed by two-way ANOVA.

RESULTS

The sample consisted of 277 elderly, 151 with hypoalbuminemia and those using an average of 6.6 +/- 3.80 different prescription drugs most of which had affinity for albumin (4.96 +/- 2.64). Results showed that the number of drugs with affinity for albumin and hospital stay were predictors of death (r = 0.47, R2 = 0.224), (F(8.170) = 6.13; p=0.001). The relation between dependent and independent variables resulted in the mathematical equation: (death= 0.545 - 0.374 (albumin) - 0.195 (days of hospitalization) + 0.175 (number of drugs with affinity for albumin)).

CONCLUSION

The mathematical equation obtained by this study demonstrated that albumin and days of hospitalization were inversely correlated with death and directly correlated with the number of drugs bound to albumin.

Análise do perfil de automedicação em mulheres idosas brasileiras

Idosos compõem o grupo etário mais medicalizado na sociedade, o que pode levar ao uso irracional de fármacos. Este trabalho descreve estudo transversal que avaliou a automedicação de idosas atendidas no ambulatório de Atenção ao Idoso do Hospital da Universidade Católica de Brasília. As variáveis socioeconômicas analisadas consistiram na faixa etária, escolaridade e renda familiar mensal. As classes medicamentosas envolvidas em automedicação foram analisadas conforme prevalência, adequação à faixa etária e possíveis interações medicamentosas. Das 218 pacientes entrevistadas, 26% relataram praticar automedicação. Parcela (40%) desses medicamentos era de venda sob prescrição. Medicamentos antiinflamatórios, analgésicos e antipiréticos foram os mais usados sem orientação profissional, seguido pelos fitoterápicos/medicamentos naturais e cardiovasculares. Entre as pacientes automedicadas, 65% apresentaram baixa escolaridade, enquanto 32% apresentaram renda menor ou igual a um salário mínimo. O consumo por automedicação não se mostrou variar conforme a condição socioeconômica. Foram observadas interações medicamentosas potencialmente severas e uso impróprio envolvendo os eventos de automedicação.

Retail prices of essential drugs in Brazil: an international comparison

OBJECTIVES

Price is a key obstacle for consumer access to essential drugs, especially in developing countries. This study sought to compare the retail prices of essential drugs on the private market in Brazil with that of two international pricing standards.

METHODS

The retail price of all drugs on Brazil's Essential Drugs List, July 2000 edition, were compared to the retail price of the same drugs on the Swedish market and on a referential bulk-price indicator from low-cost suppliers on the international market. Ratios of Brazil's prices to Sweden's prices and Brazil's prices to the international bulk mean price-per-unit for each drug were calculated. Using linear regression analysis, the ratios were also studied in relation to the number of manufacturers.

RESULTS

For the 132 drugs that were listed on both Brazil's and Sweden's lists, unitary retail prices in Brazil were 1.9 times higher. Of the 94 drugs found on both Brazil's list and the international unit-price indicator, Brazil's national mean unit prices were 13.1 more expensive. No relationship was found between the number of manufacturers for each product and the ratios of prices.

CONCLUSIONS

Average retail prices of essential drugs in Brazil are significantly higher than in Sweden. Furthermore, international bulk prices indicate that drugs are brought to market by Brazil's private pharmacies at prices that may be excessively high in relation to production costs, creating high profit margins. The expected price-lowering effects of competition were not identified.

Non-alcoholic fatty liver disease and metabolic syndrome in Brazilian middle-aged and older adults

CONTEXT AND OBJECTIVES

Non-alcoholic fatty liver disease (NAFLD) is a complex clinicopathological entity characterized by diffuse or focal fat accumulation in the hepatic parenchyma of patients who deny abusive alcohol consumption. This study aimed to assess idiopathic NAFLD in community-dwelling, middle-aged and older adults living in the Brazilian Federal District. Associations between NAFLD and components of metabolic syndrome and the whole syndrome were investigated.

DESIGN AND SETTINGS

This was a cross-sectional study on 139 subjects aged 55 years or older.

METHODS

NAFLD was diagnosed by means of clinical procedures, to exclude subjects with signs of liver disorders, abusive alcohol consumption and influence from hepatotoxic drugs. Phenotypes were graded based on ultrasound examination. Metabolic syndrome was defined using the NCEP ATP III criteria. Laboratory tests were performed to assist clinical examinations and define the syndrome. RESULTS NAFLD was present in 35.2% of the subjects. Taken together, the two most intense phenotypes correlated with increased serum fasting glucose, triglyceride and VLDL cholesterol levels. Metabolic syndrome was diagnosed in 25.9% of the sample. In addition to associating NAFLD with specific traits of metabolic syndrome, non-parametric analysis confirmed the existence of a relationship (p < 0.05) between the steatotic manifestation and the syndromic condition.

CONCLUSION

Compared with the literature, this study reveals greater frequency of idiopathic NAFLD among Brazilian middle-aged and older adults than is described elsewhere. The findings also suggest that impaired glycemic metabolism coupled with increased fat delivery and/or sustained endogenous biosynthesis is the most likely physiopathogenic mechanisms underlying the onset of NAFLD in this population.

An estimation of the frequency of gestational toxoplasmosis in the Brazilian Federal District

Acute infections by the protozoan Toxoplasma gondii during pregnancy (gestational toxoplasmosis) are known to cause serious health problems to the fetus (congenital toxoplasmosis). In Brasília, there have been few studies on the incidence of toxoplasmosis. This report summarizes a retrospective study performed on 2,636 selected pregnant women attended by the public health system of Guará, a satellite-city of Brasília. In this survey, 17 cases of gestational toxoplasmosis were detected; 15 of which were primary maternal infection and the remaining 2 were consistent with secondary maternal infection. These results suggest an annual seroconversion rate of 0.64 percent (90 percent confidence interval: 0.38, 0.90).

A terapia medicamentosa no idoso: cuidados na medicação

A literatura médica reconhece que o envelhecimento predispõe a um consumo aumentado de medicamentos prescritos e não-prescritos. No entanto, mudanças fisiológicas relacionadas ao envelhecimento, tais como a modificação da composição corporal e a redução das funções renal e hepática, podem alterar em muito a farmacocinética e a farmacodinâmica de diversos fármacos, fazendo com que indivíduos idosos estejam suscetíveis com maior freqüência a efeitos adversos ou terapêuticos mais intensos. Neste cenário, a literatura médica tem sido constantemente enriquecida com estudos que apontam explicitamente para medicamentos específicos ou categorias de medicamentos cujo consumo por indivíduos idosos deve ser evitado ou utilizado com cautela. Este trabalho se propõe a descrever brevemente algumas informações consensuais acerca destes medicamentos impróprios para idosos, ressaltando alguns fármacos que se encontram disponíveis à população brasileira.

Access to Essential Drugs in 11 Brazilian Cities: A Community-based Evaluation and Action Method

The Brazilian Institute for Defense of Consumers' (IDEC) health and legal professionals gathered with partner associations and researchers from the University of Brasilia shaped this study to develop and apply simple methods for community and consumer organizations to monitor the availability of essential drugs for primary care in their local public health services. A cross-sectional study was conducted in 11 Brazilian cities. The instrument gave priority to the feasibility of use by community organizations over statistically representative designs. It also worked from the assumption that all Health Centers should stock the drugs recommended for ambulatory care on Brazil's national list of essential drugs, in agreement to federal legislation. The instrument was found to be feasible for use by the participating organizations, and its utilization revealed a picture of severe deficiency of essential medicines in the Brazilian public health system, expressed as an overall availability of only 55.4% of the 61 drugs investigated. Models for legal action in support of individual and community access to essential drugs were developed by IDEC's legal staff to assist community organization in following up the results with an action program. These models were made available on the organization's web-site and widely disseminated nationally.

Polymyositis: clinical investigation in two sisters

We present an investigation of a case of polymyositis affecting two sisters of one same parenthood. Their cases have been documented for almost two decades, being investigated by means of a diagnostic protocol which combined clinical findings as well as laboratorial, histopathological and image tests. In both cases, clinical manifestations started in childhood, without signs of involvement of the central and peripheral nervous system. Both patients proved to respond to a therapeutics based on corticosteroids. The degree of relatedness between their parents corroborate the notion that genetic factors may contribute to the development of the disease.
