Background:The complexity of a medication regimen is related to the multiple characteristics of the prescribed regimen and can negatively influence the health outcomes of patients.Objective:To propose cut-off points in the complexity of pharmacotherapy to distinguish between patients with low and high complexities seen in a primary health care (PHC) setting to enable prioritization of patient management.Methods:This is a cross-sectional study, which included 517 adult and elderly patients, analyzing different cut-off points to define the strata of low and high pharmacotherapy complexities based on percentiles of the population evaluated. Data collection began with the solicitation of prescriptions, followed by a questionnaire that was administered by an interviewer. The complexity of a medication regimen was estimated from the Medication Regimen Complexity Index (MRCI). High complexity pharmacotherapy scores were analyzed from patient profiles, the use of health services, and pharmacotherapy. The criteria for subject inclusion in the sample population were as follows: inhabitant of the area covered by the municipality, 18 years or older, and being prescribed at least one drug during the collection period. Exclusion criteria at the time of collection were the use of any medication whose prescription was not available. All medications were accessed through the Primary Healthcare Service (PHS).Results:The median total pharmacotherapy complexity score was 8.5. High MRCI scores were correlated with age, medications taken with in the Brazilian PHS, having at least one potential drug-related problem, receiving up to eight years of schooling, number of medications and polypharmacy (five or more medicines), number of medical conditions, number of medical appointments, and number of cardiovascular diseases and endocrine metabolic diseases. We suggest different complexity tracks according to age (e.g., adult or elderly) that consider the pharmacotherapy and population coverage characteristics as high complexity limits. For the elderly patients, the tracks were as follows: MRCI≥25.4, MRCI≥20.9, MRCI≥17.5, MRCI≥15.7, MRCI≥14.0, and MRCI≥13.0. For adult patients, the limits of high complexity were MRCI≥25.1; MRCI ≥ 23.8; MRCI≥21.0; MRCI≥17.0; MRCI≥16.5; and MRCI≥15.5.Conclusion:The medication regimen complexity is associated with the patient’s illness profile and problems with the use of drugs; therefore, the proposed scores can be useful in prioritizing patients for clinical care by pharmacists and other health professionals.

This study evaluates whether the integration of pharmacists into health-care teams through the delivery of pharmaceutical care-based medication therapy management (MTM) services can improve the clinical outcomes of patients with chronic health conditions in the primary health-care setting. A retrospective descriptive study of 92 outpatients assisted by MTM pharmacists in primary health-care units was carried out over 28 months (median follow-up: 05 months). Patients were followed up by MTM pharmacists, with a total of 359 encounters and a ratio of 3.9 encounters per patient. The prevalence of hypertension, diabetes mellitus and dyslipidaemia was 29.5%, 22.0% and 19.4%, respectively. There was a high prevalence of drug-related problems with a ratio of 3.4 per patient. Pharmacists performed a total of 307 interventions to prevent or resolve drug-related problems. With regard to control of the most prevalent chronic medical conditions, a high percentage of patients reached their therapy goals by the last encounter with the pharmacist: 90.0% for hypertension, 72.3% for diabetes mellitus and 90.3% for dyslipidaemia. MTM services provided by pharmacists resolved drug therapy problems and improved patients' clinical outcomes. This study provides evidence for health-care managers of the need to expand the clinical role of pharmacists within the Brazilian public health-care system.

Objective: To analyze the context of drug use in children aged zero to five years old.Methods: Cross-sectional study based on interviews conducted at home with caregivers (parents, uncles or grandparents) of the children enrolled in ten Family Health Strategy units across different geographical points of the city of Tubarão, Santa Catarina, Brazil.Results: A total of 350 caregivers were interviewed, whose children’s mean age was 2.6 years. Of these, 56.9% had used at least one drug in the 15 days prior to the interview, 31.1% had been exposed to self-medication and 35.7% had used at least one medication obtained by current prescription. The use of medication was associated with the age range up to 24 months, periodic consultation with pediatricians and diagnosis of chronic and acute diseases. Among medicated children, 19.1% inappropriately had been exposed to at least one medication (considering dose, dose interval or period of treatment). Regarding medication storage, 55.2% of interviewees stored them in unsafe places that could be accessed by children and 32.0% in inappropriate places, with exposure to light, heat or humidity. Moreover, 45.2% of the interviewees stored drugs out of their packages, 38.9% without secondary packaging, and 1.6% of drugs had expired date.Conclusions: Drug use is high among children in this age range, and actions aimed at the safe and rational use of these substances in this population should be encouraged.

Pulmonary tuberculosis (PTB) develops by a complex combination of environmental, immunological and socioeconomic factors and genetic susceptibility. The human leukocyte antigen (HLA) is the most polymorphic biological system and plays an essential role in the immune response against PTB. The aim of this study was to carry out a systematic review and meta-analysis evaluating the relationship between HLA-DRB1, HLA-DQB1 and HLA-DQA1 gene polymorphisms as possible risk or protective factors for PTB. A systematic search of the PubMed and Scopus databases was conducted following the guidelines described in the PRISMA statement. Fifty-six alleles were included in the meta-analysis. In the total pooled results, HLA-DRB1*08:03 (OR 1.95, CI 1.29-2.96), HLA-DQB1*06:01 (OR 1.78, CI 1.39-2.28), HLA-DQB1*06:09 (OR 2.27, 95 % CI 1.04-4.96) and HLA-DQA1*01:01 (OR 2.12, CI 1.11-4.03) genes were related to higher susceptibility to PTB. Conversely, the presence of the genes HLA-DRB1*07:01 (OR 0.74, CI 0.56-0.97), HLA-DQB1*03:01 (OR 0.77, CI 0.61-0.97), HLA-DQB1*04:02 (OR 0.57, CI 0.39-0.83), HLA-DQA1*04:01 (OR 0.50, CI 0.26-0.95) and HLA-DQA1*05:01 (OR 0.66, CI 0.48-0.92) demonstrated protection against PTB. In an analysis by ethnic subgroups, we found more genetic associations in Caucasians than in Asians. These findings suggest that HLAs may be used as markers for acquisition and development of PTB. To strengthen PTB susceptibility/resistance, we recommend further multicentric studies in different geographic regions, with certainty of controls' exposure to M. tuberculosis by use of marker of latent or active PTB, with analysis stratified by ethnic groups, with descriptions of specific alleles and carrying out immunological functionality tests.

Myrciaria floribunda, also known as rumberry, is a tree native to the Brazilian Atlantic Forest, where its fruits have the potential for commercial use. This study evaluates the antioxidant potential, determines the phytochemical profile, and chemically characterizes the rumberry fruit. Accessions were sampled from the Rumberry Active Germplasm Bank of the Federal University of Alagoas, Brazil. Physical characteristics, chemical characteristics, and phenolic compound content were analyzed. Chemical profile characterization was carried out using PSMS. Accessions had an average weight of 0.86 g. Accession AC137 presented a higher pulp yield (1.12 g). AC132 and AC156 had larger fruits, AC137 showed greater firmness (5.93 N), and AC160 had a higher and total phenolic content ratio (279.01 ± 11.11). Orange-colored accessions scored higher in evaluated parameters, except for AC160 for phenolic content. Thirty-two compounds were identified on positive ionization mode and 42 compounds on negative ionization mode using PSMS. Flavonoids, followed by the derivatives of benzoic acid, sugars, and phenylpropanoids, were the most prominent. Myricitrin, quercitrin, and catechin stand out as flavonoids that have been reported in previous studies with antioxidant and antimicrobial properties, in addition to health and therapeutical benefits, demonstrating the potential of the rumberry fruit.
