    Climacteric symptoms and quality of life in yoga practitioners.
    (2020) Souza, Laura Alves Cota e; Reis, Ilka Afonso; Lima, Angélica Alves
    Background: Yoga is among the most commonly studied complementary therapies for managing climacteric symptoms. However, it is unclear whether yoga practices in premenopause can affect the occurrence of symptoms when women reach menopause. Objective: To assess climacteric symptoms and quality of life in regular yoga practitioners and to determine whether yoga practices before menopause may avoid or mitigate climacteric-related symptoms. Design: This study of 108 women between 40 and 65 years old included 28 women who started to practice yoga in premenopause and had already practiced for at least five years, and as controls 30 physical activity practitioners (PA) who had practiced for at least five years, and 50 sedentary women. Main outcome measures: Climacteric symptoms were evaluated with the Kupperman Menopausal Index (KMI) and the Women’s Health Questionnaire (WHQ). Moreover, we measured the quality of life with the WHQ. Results: The KMI showed that 39.3% of yoga practitioners had no menopausal symptoms, and none reported severe symptoms. The WHQ indicated a few symptoms and a good quality of life for yoga practitioners (3.56; 3.353.80). In addition, we found that the yoga group had significantly less moderate and severe symptoms (p = 0.002) compared with the sedentary group. We also observed that yoga practitioners had less vasomotor symptoms and memory/concentration disorders than PA practitioners (p = 0.010 and p = 0.047) and sedentary women (p = 0.001 and p = 0.001) and also used fewer drugs than the PA (p < 0.001) and the sedentary groups (p = 0.001). Conclusions: Yoga practitioners who started to practice in premenopause had satisfactory results on the frequency and intensity of climacteric symptoms and quality of life. Although further research is required to support our findings, we conclude that yoga practice may represent an efficient non-pharmacological approach to manage and prevent climacteric symptoms.

    (2013) Marinho, Flávia Dias Marques; Reis, Ilka Afonso; Soares, Cristina Duarte Vianna
    Métodos analíticos requerem modelos adequados de ajuste de curva para expressar confiabilidade. Métodos dos mínimos quadrados ordinários ou ponderado (OLSM ou WLSM, respectivamente) foram usados para determinar o modelo matemático mais adequado à curva analítica, iniciando-se do método mais simples (linear) até o quadrático. A normalidade e a homocedasticidade dos resíduos dos modelos foram avaliadas. Curvas analíticas foram construídas pela injeção de 1, 5, 10, 15 e 20 L de sinvastatina 40 μg mL–1 (40, 200, 400, 600 e 800 ng) ou de 10 L de sinvastatina 4, 20, 40, 60 e 80 μg mL–1, empregando cromatografia líquida de alta eficiência com detecção por arranjo de diodos (238 nm). Os melhores modelos foram o linear e o quadrático observados para os conjuntos de dados massas e concentrações, respectivamente. Na faixa de trabalho considerada, WLSM mostrou-se mais apropriado que OLSM. Os diferentes comportamentos apontam para a necessidade de uma escolha sensata do modelo mais adequado para expressar a curva analítica e assegurar a confiabilidade do método utilizado.

    (2019) Brito, Daniela Cristina Sampaio de; Machado, Elaine Leandro; Reis, Ilka Afonso; Carmo, Lilian Pires de Freitas do; Cherchiglia, Mariângela Leal
    BACKGROUND: Depression and anxiety are the most prevalent psychological disorders among end-stage renal disease patients and are associated with various conditions that result in poorer health outcomes, e.g. reduced quality of life and survival. We aimed to investigate the prevalences of depression and anxiety among patients undergoing renal replacement therapy. DESIGN AND SETTING: Cross-sectional study in Belo Horizonte, Brazil. METHODS: Patients’ depression and anxiety levels were assessed using the Beck Inventory. The independent variables were the 36-Item Short-Form Health Survey (SF-36), Charlson Comorbidity Index and Global Subjective Assessment, along with sociodemographic and clinical characteristics. RESULTS: 205 patients were included. Depression and anxiety symptoms were detected in 41.7% and 32.3% of dialysis patients and 13.3% and 20.3% of transplantation patients, respectively. Lower SF-36 mental summary scores were associated with depression among transplantation patients (odds ratio, OR: 0.923; 95% confidence interval, CI: 0.85-0.99; P = 0.03) and dialysis patients (OR: 0.882; 95% CI: 0.83-0.93; P ≤ 0.001). Physical component summary was associated with depression among dialysis patients (OR: 0.906; 95% CI: 0.85-0.96; P = 0.001). Loss of vascular access (OR: 3.672; 95% CI: 1.05-12.78; P = 0.04), comorbidities (OR: 1.578; 95% CI: 1.09-2.27; P = 0.01) and poorer SF-36 mental (OR: 0.928; 95% CI: 0.88-0.97; P = 0.002) and physical (OR: 0.943; 95% CI: 0.89-0.99; P = 0.03) summary scores were associated with anxiety among dialysis patients. CONCLUSIONS: Depression and anxiety symptoms occurred more frequently among patients undergoing dialysis. Quality of life, comorbidities and loss of vascular access were associated factors.

    (2018) Rocha, Iara Caixeta Marques da; Santos, Letícia Helena Marques dos; Vital, Wendel Coura; Cunha, Gisele Macedo Rodrigues da; Magalhães, Fernanda do Carmo; Silva, Thais Almeida Marques da; Morais, Maria Helena Franco; Oliveira, Edward; Reis, Ilka Afonso; Carneiro, Mariângela
    Background Control strategies adopted by the Brazilian Visceral Leishmaniasis Surveillance and Control Programme (VLSCP) include identifying and culling seropositive infected dogs, early diagnosis and treatment of human cases, chemical control of the vector and population awareness. This study evaluated the effectiveness of the VLSCP on the prevalence and incidence rates of Leishmania infantum in children residing in areas under different VLSCP intervention times. Methods A quasi-experimental epidemiological study with a panel (two cross-sectional) and a concurrent cohort was performed in three areas of Belo Horizonte, southeast Brazil. The first cross-sectional study (I) was carried out with 1875 children, 478 of which were enrolled in the cohort study. In the second cross-sectional study (II), 413 additional children were included, totalizing 891 children. Laboratory diagnosis was performed by ELISA-rK39. Analyses included multilevel logistic and Poisson regression models. Results The incidence rates of L. infantum infection were: 14.4% in the area where VLSCP intervention was initiated in 2006 (AI2006); 21.1% in the area where intervention was initiated in 2008 (AI2008); and 11.6% in the area where intervention was initiated in 2010 (AI2010 - control area). A follow-up period of 24 months showed that the persons-time incidence rates in AI2006, AI2008, and AI2010 were: 6.2/100, 10/100, and 5.6/100 persons/24 months, respectively. The final prevalence rates of infection (cross-sectional II - in 2012), compared to the initial rates (cross-sectional I - in 2010), increased 83.7% in AI2006, 74.1% in AI2008, and decreased 5% in AI2010. Analysis of the effectiveness revealed that children residing in AI2008 are more likely to be infected (OR = 1.84; 95% CI: 1.06-3.23) and present a higher risk of infection (IRR = 1.76; 95% CI: 1.05-2.95) compared to those in AI2010. No statistically significant differences were observed in asymptomatic infection (OR and IRR) in AI2006 compared to AI2010. Conclusions The VLSCP was not effective at controlling L. infantum infection in areas where interventions had respectively been carried out for six and four years. However, it is unclear what the consequences in terms of human infection and diseases would be in the absence of the VLSCP. Efforts to improve the effectiveness of control measures remain a necessary priority.

    Impact of clinical, sociodemographic and quality of life factors on dialysis patient survival : a nine-year follow-up cohort study.
    (2020) Brito, Daniela Cristina Sampaio de; Machado, Elaine Leandro; Reis, Ilka Afonso; Cherchiglia, Mariângela Leal
    Although renal replacement therapy has contributed to the survival of chronic kidney failure (CKF) patients, mortality remains a major concern. This study aimed to identify the factors associated with mortality in a prospective cohort of CKF patients. Sociodemographic, clinical, nutritional, lifestyle and quality of life data were collected from 712 patients. The instruments used were the Short-Form Health Survey (SF-36), Global Subjective Assessment (GSA) and Charlson Comorbidity Index (CCI) questionnaires. A total of 444 patients died during the study. After five years of follow-up, factors such as not being married (hazard ratio – HR = 1.289, 95%CI: 1.001; 1.660), a low frequency of leisure activities (HR = 1.321; 95%CI: 1.010; 1.727) and not be ing transplanted (HR = 7.246; 95%CI: 3.359; 15.630) remained independently associated with the risk of mortality. At the end of the follow-up period, factors such as not being married (HR = 1.337, 95%CI: 1.019; 1.756), not being transplanted (HR = 7.341, 95%CI: 3.829; 14.075) and having a worse nutritional status (HR = 1.363, 95%CI: 1.002; 1.853) remained independently associated with an increased risk of mortality, whereas a high schooling level (10 to 12 years, HR = 0.578, 95%CI: 0.344; 0.972; and over 12 years, HR = 0.561, 95%CI: 0.329; 0.956) and a better SF-36 physical functioning score (HR = 0.992, 95%CI: 0.987; 0.998) were protective factors associated with survival. The survival of patients with CKF is associated with factors not restricted to the clinical spectrum. The following factors were associated with high mortality: not being married, low schooling level, a limited social routine, a longer time on dialysis, worse nutritional status, and worse physical functioning.

    Influência da temperatura em estudos de dissolução de formas farmacêuticas contendo sinvastatina.
    (2012) Marinho, Flávia Dias Marques; Diniz, Mirella Monique Lana; Zanon, José Carlos da Costa; Reis, Ilka Afonso; Lima, Angélica Alves; Soares, Cristina Duarte Vianna
    O antihiperlipêmico sinvastatina está disponível no mercado nacional na forma de comprimidos e cápsulas manipuladas. Método por cromatografia a líquido de alta eficiência com detecção no ultravioleta (l 238 nm) foi utilizado para quantificar sinvastatina em cápsulas e comprimidos em tampão fosfato de sódio monobásico 0,01 M contendo laurilsulfato de sódio 0,5%, pH 7, utilizado como diluente ou meio de dissolução. A estabilidade de curto prazo do fármaco das amostras foi avaliada no diluente, mantido a diferentes temperaturas. A estabilidade de curto prazo (até 24 h) de soluções de sinvastatina, não submetidas ao teste de dissolução, foi satisfatória para o fármaco isolado e para cápsulas, o que não se verificou para comprimidos. A estabilidade da sinvastatina em soluções mantidas a 22-24 ºC por 8 h, após o teste de dissolução foi satisfatória para o fármaco isolado e para cápsulas contendo butilhidroxitolueno como excipiente. Os resultados de amostras de sinvastatina cápsulas contendo vitamina B12 e de comprimidos indicam a necessidade de refrigeração das soluções em estudos de dissolução, caso a análise cromatográfica tenha duração superior a 4 h e 2 h, respectivamente, como descrito.

    Modality transition on renal replacement therapy and quality of life of patients : a 10-year follow-up cohort study.
    (2019) Brito, Daniela Cristina Sampaio de; Machado, Elaine Leandro; Reis, Ilka Afonso; Moreira, Daniela Pena; Nébias, Thiago Henrique Mascarenhas; Cherchiglia, Mariângela Leal
    Purpose Despite advance in renal replacement therapy (RRT), patients with chronic end-stage renal disease (ESRD) face various limitations, and renal transplantation (Tx) is the treatment that impacts most on quality of life (QoL). This study aimed to assess changes in QoL in a cohort of ESRD dialysis patients. Methods Sociodemographic, clinical, nutritional, lifestyle, and QoL data were collected from 712 patients at baseline (time 1) and after 10 years of follow-up (time 2) for patients surviving. The QoL was assessed through the 36-Item Short Form Health Survey (SF-36) and the multiple linear regression model was used to analyze the factors associated with change in QoL. Results A total of 205 survivors were assessed and distributed into three groups according to current RRT (Dialysis–Dialysis, Dialysis–Tx, and Dialysis–Tx–Dialysis). At time 1, only age was significantly different among groups; at time 2, transplant patients sustained greater social participation, job retention, and improvement in SF-36 scores. The factors associated with change in QoL were more time on dialysis interfering negatively on physical functioning (p=0.002), role-physical limitations (p =0.002), general health (p =0.007), social functioning (p=0.02), role-emotional (p = 0.003), and physical components ( p =0.002); non-participation in social groups at times 1 and 2 reducing vitality (p=0.02) scores; and having work at time 2, increasing vitality (p=0.02) and mental health (p =0.02) scores. Conclusions QoL was shown to be dynamic throughout the years of RRT, transplantation being the treatment with more benefits to the ESRD. More time on dialysis and limited social and occupational routine were associated with a reduction in QoL.

    A qualidade, o custo e a dispensação de sinvastatina cápsulas em farmácias magistrais.
    (2013) Marinho, Flávia Dias Marques; Prado, Ana Paula da Silva; Zanon, José Carlos da Costa; Reis, Ilka Afonso; Lima, Angélica Alves; Soares, Cristina Duarte Vianna
    Com base na RDC/ANVISA 67/2007, avaliou-se o serviço prestado na dispensação de sinvastatina cápsulas em farmácias magistrais. Vinte e quatro (16%) das 150 farmácias magistrais foram aleatoriamente selecionadas nas regiões de Belo Horizonte-MG, observando a distribuição geográfica. A qualidade do produto, os aspectos da dispensação e o custo foram considerados em estudos de correlação. Os resultados foram submetidos a análises estatísticas descritivas e inferenciais. Em apenas 25% destas farmácias, o fax da prescrição foi solicitado. Todos os pedidos foram entregues no prazo, porém sem comprovação da dispensação. Em uma das entregas, o medicamento era o incorreto. Seis (25%) dos produtos apresentaram rotulagem incompleta (ausência de posologia 16,3% ou de identificação do médico/paciente 8,7%). Apenas 11 (45,8%) das amostras apresentaram qualidade satisfatória. O custo do medicamento manipulado variou entre R$20,40 e R$44,00 com valor médio R$31,18. Não se observou associação entre a qualidade do medicamento e os aspectos do custo, prazo de entrega e localização geográfica. Verifica-se que a maioria das farmácias magistrais ainda precisa adequar-se à legislação para garantir à população uma assistência farmacêutica de qualidade.

    (2011) Marinho, Flávia Dias Marques; Zanon, José Carlos da Costa; Sakurai, Emília; Reis, Ilka Afonso; Lima, Angélica Alves; Soares, Cristina Duarte Vianna
    No Brasil, a sinvastatina está comercialmente disponível na forma de comprimidos e cápsulas manipuladas. Poucos relatos estão disponíveis sobre a qualidade e, consequentemente, a eficácia dessas cápsulas. A qualidade de 30 lotes de sinvastatina 20 mg cápsulas do mercado foi avaliada através da determinação de peso, uniformidade de conteúdo, desintegração (Farmacopéia Brasileira), doseamento e teste de dissolução (monografia comprimidos USP32). Método por CLAE foi desenvolvido para o doseamento, uniformidade de conteúdo e teste de dissolução; além disso, especificações foram estabelecidas. Dos 30 lotes avaliados, 29 apresentaram desintegração da cápsula até 45 min e a variação do peso individual foi ± 10% ou ± 7,5% em relação ao peso médio, se ≤ ou > 300 mg, respectivamente. Apenas 27 lotes preencheram os critérios do teste de dissolução com valores ≥ 80% da quantidade rotulada, em 45 min, 21 lotes apresentaram conteúdo de sinvastatina entre 90,0-110,0% do valor rotulado e 19 lotes apresentaram pelo menos 9 em 10 cápsulas, com valores de uniformidade de conteúdo entre 85,0 -115,0% da quantidade rotulada com RSD ≤ 6,0%. Apenas 14 de todos os lotes (30) atenderam completamente os padrões de qualidade farmacopéicos. O estabelecimento das condições para os testes e de especificações para os parâmetros das cápsulas de sinvastatina mostrou que houve diferenças relevantes na qualidade farmacopeica entre os lotes das cápsulas manipuladas por distintas farmácias. A eficácia do tratamento hipercolesterolêmico poderia estar comprometida para 53,33% dos produtos testados.

    (2012) Marinho, Flávia Dias Marques; Santos, Amanda Leão dos; Soares, Cristina Duarte Vianna; Reis, Ilka Afonso; Zanon, José Carlos da Costa; Lima, Angélica Alves
    Commonly used HPLC acetonitrile solvent has been through a worldwide shortage with a cost increase in 2008 and 2009. In order to get around this situation, a method by RP-HPLC employing methanol and aqueous acid mobile phase was developed and validated to evaluate simvastatin. The quality control assay and dissolution studies of this lipid-lowering drug were performed in diluents methanol and 0.01 M phosphate buffer with 0.5% SDS, pH 7, respectively. Dissolution test aliquots did not go through sample treatment, as described in USP SIM tablets monograph by ultraviolet spectrophotometry. The proposed method is fast, simple, feasible and robust.

    Spatial and temporal trends of visceral leishmaniasis by mesoregion in a southeastern state of Brazil, 2002-2013.
    (2017) Silva, Thais Almeida Marques da; Vital, Wendel Coura; Barbosa, David Soeiro; Oiko, Carla Sayuri Fogaça; Morais, Maria Helena Franco; Tourinho, Bruna Dias; Melo, Diogo Portella Ornelas de; Reis, Ilka Afonso; Carneiro, Mariângela
    This article presents the spatial and temporal distribution of visceral leishmaniasis (VL) in Minas Gerais State and identifies the greater risk areas of transmission. This study is both timely and substantive because Minas Gerais is an important Brazilian state in the number of cases of visceral leishmaniasis. The results showed that during the 12-year time series the VL had a heterogeneous spatial and temporal distribution in the state of Minas Gerais. Among the 12 existing mesoregions, six (Central Mineira, Jequitinhonha, Metropolitan area of Belo Horizonte, Northwest of Minas, North of Minas, and Vale do Rio Doce) were responsible for the expansion and maintenance of VL in the state. Among them, the Vale do Rio Doce and Jequitinhonha mesoregions presented a considerable increase in the incidence rates of the disease in the last period. In the other six mesoregions only sporadic cases of the disease were reported during the study period. The results of in this study may contribute to a better understanding the dynamic of the disease in Minas Gerais. Also these findings can provide subsidies to assist the actions of the control program of VL.

    Spatiotemporal dynamics and risk estimates of COVID-19 epidemic in Minas Gerais State : analysis of an expanding process.
    (2021) Vital, Wendel Coura; Cardoso, Diogo Tavares; Ker, Fabricio Thomaz de Oliveira; Magalhães, Fernanda do Carmo; Bezerra, Juliana Maria Trindade; Viegas, Ana Maria; Morais, Maria Helena Franco; Bastos, Leonardo Soares; Reis, Ilka Afonso; Carneiro, Mariângela; Barbosa, David Soeiro
    COVID-19 is an infectious disease caused by the recently discovered coronavirus SARS-Cov-2. The disease became pandemic affecting many countries globally, including Brazil. Considering the expansion process and particularities during the initial stages of the epidemic, we aimed to analyze the spatial and spatiotemporal patterns of COVID-19 occurrence and to identify priority risk areas in Minas Gerais State, Southeast Brazil. An ecological study was performed considering all data from human cases of COVID-19 confirmed from the epidemiological week (EW) 11 (March 08, 2020) to EW 26 (June 27, 2020). Crude and smoothed incidence rates were used to analyze the distribution of disease patterns based on global and local indicators of spatial association and space-time risk assessment. Positive spatial autocorrelation and spatial dependence were found. Our results suggest that the metropolitan region of the State capital Belo Horizonte (MRBH) and Vale do Rio Doce mesoregions, as major epidemic foci in the beginning of the expansion process, have had important influence on the dispersion of SARS-CoV-2 in Minas Gerais State. Triangulo Mineiro/Alto Paranaiba region presented the highest risk of infection. In addition, six statistically significant spatiotemporal clusters were identified in the State, three at high risk and three at low risk. Our findings contribute to a greater understanding of the space-time disease dynamic and discuss strategies for identification of priority areas for COVID-19 surveillance and control.
