Gestational diabetes and overt diabetes first diagnosed in pregnancy: characteristics, therapeutic approach and perinatal outcomes in a public healthcare referral center in Brazil.

OBJECTIVE: To describe the clinical characteristics, management, and fetal outcomes of patients diagnosed with gestational diabetes mellitus (GDM) or overt diabetes (OD) during pregnancy who followed up at a public healthcare referral center in Brazil. METHODS: A retrospective cohort study based on the medical records of women diagnosed with dysglycemia during pregnancy between January 2015 and July 2017 was conducted. RESULTS: Out of 224 pregnant women evaluated, 70% were overweight/obese. GDM was observed in 78.6% of pregnant women, while 21.4% presented with OD. Approximately 59% of patients could be diagnosed with GDM or OD by fasting plasma glucose (FPG) alterations alone. Exclusive diet therapy was used in 50.9% of patients. The need for insulin therapy was higher in OD patients (60.4%) than in GDM patients (38.1%) (p = 0.006). Women who needed insulin (n = 96) had a mean initial dose of 0.33 IU/kg (±0.27) and a final value of 0.39 IU/kg (±0.34). The cesarean rate was 74.3%. The fetal outcomes evaluated were macrosomia (2.15%), large for gestational age (LGA) fetus (15.83%), intensive care unit (ICU) need (4.32%), Apgar score ≤7 (6.47%), hypoglycemia (14.39%) and jaundice (16.55%). CONCLUSION: Patients with GDM and OD presented with several similar clinical features. Approximately half of the patients presented with adequate glycemic control only with diet management. Patients with OD presented a higher need for insulin therapy. Although overweight and obesity were frequent within both groups, they could possibly explain many of our findings.

Long-term real-life outcomes in a georrefered cohort of acromegalic patients in Brazil.

PURPOSE: Epidemiological data on acromegaly therapeutic outcomes in real-life conditions are scarce in Brazil. Information on the geographical accessibility to the dispensation of medicines and its impact on biochemical control is also poorly known. We aimed to describe the clinical outcomes of long-term therapy in patients with acromegaly at a referral medical centre in Brazil and to perform a spatial analysis of patients according to the distance from home to the drug-dispensing pharmacies aiming to evaluate its impact on biochemical control. METHODS: Global retrospective data analysis of 111 patients followed at the University Hospital of Brasília from January 1980 to March 2015 was performed, as well as a separate review of 17 new cases operated on from April 2015 to June 2019 according to surgery results. Spatial analysis of patients under pharmacological treatment applying Geographic Information System (GIS) software (ArcGIS, ESRI, Redlands, CA) was performed. RESULTS: Considering surgery alone, the cure rate was 23% from 1980 to 2015 and 29.4% from 2015 to 2019. In the long-term follow-up of the 111 patients from 1980 to 2015, 25.2% (n = 29) were cured, 40.6% (n = 44) presented controlled disease and 34.2% (n = 38) were biochemically uncontrolled after a period of follow-up of 8.9 ± 6.4 years. Biochemical control obtained in patients on pharmacological treatment (n = 76) was 58% (n = 44) after 5.8 ± 3.8 years. The distance from home to the drug-dispensing pharmacy did not influence biochemical control (p = 0.7616). CONCLUSIONS: Most patients presented with disease under control. No evidence on the effect of the distance between home and drug-dispensing pharmacies on biochemical control was obtained.

Economics of Acromegaly Treatment in Brazil: A Budget Impact Analysis of Pituitary Surgery Compared with Long-Term Octreotide LAR.

BACKGROUND: Acromegaly is a rare, chronic and debilitating disease whose treatment places a high burden on health systems. In the reality of the Brazilian public health network, many patients are kept on drug treatment because of barriers to access to surgery. OBJECTIVE: The aim of this study was to estimate the costs and budget impact of routine transsphenoidal endoscopic surgery in relation to those of long-term drug treatment with octreotide long-acting release (LAR) from a cohort of patients followed at the referral medical centre for acromegaly treatment in the Federal District, Brazil. METHODS: Based on micro-costing data collected using mixed methods from a local perspective of the public health system, we performed a budget impact analysis (BIA) on a 3-year time horizon. Uncertainty was handled with deterministic (tornado and scenario) and probabilistic (Monte Carlo simulations) sensitivity analyses. RESULTS: Compared with the continued use of octreotide LAR at a dose of 30 mg every 28 days, the incremental budget impact of conducting two surgeries per month, considering a cure rate of 55%, could bring savings of approximately US$879,362.18 (95% CI 860,176.29-898,548.08) over 3 years. Depending on the key variable values, the savings amplitude ranged from US$431,836.39 to US$1,519,132.04. CONCLUSIONS: Improving access to surgery could result in significant cost reductions in acromegaly treatment. The present study stands out for being the first to estimate the costs of transsphenoidal surgery in the context of the public health system in Brazil.

Correlation of body composition parameters using different methods among Brazilian obese adults / Correlação de parâmetros de composição corporal utilizando diferentes métodos entre adultos obesos brasileiros

Abstract Data comparing anthropometric measurements, bioelectrical impedance analysis (BIA) and dual-energy X-ray absortiometry (DXA) parameters are somehow limited and conflicting. The objective of this study was to correlate anthropometric, BIA and DXA parameters among obese Brazilian adults with focus on the comparison with visceral adipose tissue (VAT) obtained from DXA and in the value of antropometric measurements. Fifty voluntary participants were enrolled. The Spearman correlation test was used to assess the correlation of VAT with anthropometric measurements, BIA and other DXA parameters. The intra-class correlation coefficient (ICC) was used to evaluate concordance between lean mass (LM), fat mass (FM), %body fat (%BF) and %upper body fat (%UBF) obtained from BIA and DXA. Most were female (80%) and had an average body index mass (BMI) of 39.0 (± 6.4) kg/m2. The only anthropometric measurements showing a strong correlation with VAT were abdominal circumference (AC) and waist-to-height ratio (WHtR), but just in females. There was a very good correlation for LM [ICC = 0.951 (CI = 0.913 - 0.972)], FM [ICC = 0.987 (CI = 0.977 - 0.993)], %BF [ICC = 0.961 (CI = 0.931-0.978)], and %UBF [ICC = 0.873 (CI = 0.776 - 0.928)], between data collected through BIA and DXA. Among the anthropometric measurements assessed, only AC and WHtR seems to estimate patients with abdominal fat distribution and higher VAT in females. DXA and BIA proved similar for the evaluation of LM, FM, %BF and %UBF, although DXA has the advantage of estimating VAT.

Resumo Dados comparando medidas antropométricas, análise de impedância bioelétrica (BIA) e parâmetros de absorciometria de raios-X de dupla energia (DXA) são de alguma forma limitados e conflitantes. O objetivo deste estudo foi correlacionar parâmetros antropométricos de BIA e de DXA entre adultos obesos brasileiros, com foco na comparação com tecido adiposo visceral (TAV) obtido na DXA e no valor das medidas antropométricas. Cinquenta participantes voluntários foram inscritos. O teste de correlação de Spearman foi utilizado para avaliar a correlação do TAV com medidas antropométricas, da BIA e de outros parâmetros da DXA. O coeficiente de correlação intra-classe (ICC) foi usado para avaliar a concordância entre massa magra (MM), massa gorda (MG), % de gordura corporal (%GC) e % de gordura corporal na parte superior do corpo (%GSC) obtidos por BIA e DXA. A maioria era do sexo feminino (80%) e apresentava índice de massa corporal médio (IMC) de 39,0 (± 6,4) kg / m2. As únicas medidas antropométricas que mostraram uma forte correlação com o TAV foram a circunferência abdominal (CA) e a relação cintura / estatura (RCE), mas apenas no sexo feminino. Houve uma correlação muito boa para MM [ICC = 0,951 (IC = 0,913 - 0,972)], MG [ICC = 0,987 (IC = 0,977 - 0,993)], % GC [ICC = 0,961 (IC = 0,931-0,978)], e % GSC [ICC = 0,873 (IC = 0,776 - 0,928)], entre os dados coletados através de BIA e DXA. Dentre as medidas antropométricas avaliadas, apenas a CA e a RCE parecem estimar pacientes com distribuição de gordura abdominal e maior TAV no sexo feminino. A DXA e a BIA mostraram-se semelhantes para a avaliação de MM, MG,% GC e % GSC, embora a DXA tenha a vantagem de estimar o VAT.

Geographical information system (GIS) as a new tool to evaluate epidemiology based on spatial analysis and clinical outcomes in acromegaly.

Geographical information systems (GIS) have emerged as a group of innovative software components useful for projects in epidemiology and planning in Health Care System. This is an original study to investigate environmental and geographical influences on epidemiology of acromegaly in Brazil. We aimed to validate a method to link an acromegaly registry with a GIS mapping program, to describe the spatial distribution of patients, to identify disease clusters and to evaluate if the access to Health Care could influence the outcome of the disease. Clinical data from 112 consecutive patients were collected and home addresses were plotted in the GIS software for spatial analysis. The buffer spatial distribution of patients living in Brasilia showed that 38.1% lived from 0.33 to 8.66 km, 17.7% from 8.67 to 18.06 km, 22.2% from 18.07 to 25.67 km and 22% from 25.68 to 36.70 km distant to the Reference Medical Center (RMC), and no unexpected clusters were identified. Migration of 26 patients from 11 others cities in different regions of the country was observed. Most of patients (64%) with adenomas bigger than 25 mm lived more than 20 km away from RMC, but no significant correlation between the distance from patient's home to the RMC and tumor diameter (r = 0.45 p = 0.20) nor for delay in diagnosis (r = 0.43 p = 0.30) was found. The geographical distribution of diagnosed cases did not impact in the latency of diagnosis or tumor size but the recognition of significant migration denotes that improvements in the medical assistance network are needed.

Physical activities in daily life and functional capacity compared to disease activity control in acromegalic patients: impact in self-reported quality of life.

OBJECTIVE: To evaluate the quality of life and its association with daily physical activity and disease control in acromegalic patients. SUBJECTS AND METHODS: A cross-sectional, case series study, composed of 42 patients recruited from the Neuroendocrinology Unit of the University Hospital of Brasilia. Level of physical activity was accessed by the International Physical Activity Questionnaire (IPAQ 6-short-form), which evaluates the weekly time spent on physical activity of moderate to vigorous intensity in different contexts of life. Quality of life was evaluated by The Medical Outcome Study Questionnaire Short Form (SF-36). Data was compared to growth hormone (GH) and insulin-like growth factor (IGF-1) levels. Students' t test and Fisher test were used, p < 0.05, SPSS 17.0. RESULTS: Twenty-two women, aged 51.33 ± 14.33 and 20 men, aged 46.2 ± 13.18 were evaluated. Arthralgia was present in 83% of cases. In men, the most common sites of pain were the knees (73%), spine (47% lumbar, and 53% thoracic and cervical segments), hands and wrists (40%). Higher scores on SF-36 were observed in patients with intermediate or high levels of physical activity, in the domains social functioning (75 CI 57.3-92.6), general health (75.5 CI 60.4-90.5), mental health (70 CI 57.8-82.1). CONCLUSIONS: In this study, the presence and severity of physical disability and pain were not associated with initial GH and IGF-1 levels or time of exposure to GH excess. However, the patients considered controlled, with normal a normal age-adjusted IGF-1, presented higher scores in SF-36, in physical and emotional domains, compared with patients with persistent hypersomatotrophism. These findings suggest benefits of metabolic control in self-reported quality of life.

Physical activities in daily life and functional capacity compared to disease activity control in acromegalic patients: impact in self-reported quality of life / Avaliação da atividade física na prática de vida diária comparada com o nível de atividade da doença em pacientes acromegálicos: impacto na percepção da qualidade de vida

OBJETIVO: Avaliar a qualidade de vida e sua associação com a prática de vida diária e controle metabólico em pacientes portadores de acromegalia. SUJEITOS E MÉTODOS: Estudo seccional de série de casos, composto por 42 pacientes recrutados na Unidade de Neuroendocrinologia do Hospital Universitário de Brasília. O nível de atividade física foi estimado pelo Questionário Internacional de Atividade Física (IPAQ-6), que avalia o tempo gasto semanalmente em atividades físicas que variam de intensidade em diferentes contextos de vida. A qualidade de vida foi avaliada pelo questionário SF-36. Os dados obtidos foram comparados aos níveis de hormônio do crescimento (GH) e fator de crescimento semelhante à insulina (IGF-1). Os testes t Students e Fisher foram aplicados e p < 0,05 foram considerados significativos, SPSS 17.0. RESULTADOS: Avaliaram-se 22 mulheres com idades de 51,33 ± 14,33 e 20 homens com idades de 46,2 ±13,18. Artralgia foi relatada em 83% dos pacientes. Em homens, os sítios de dor mais comuns foram os joelhos (73%), coluna vertebral (47% lombar, 53% segmentos torácico e cervical), mãos e quadris (40%). Os maiores escores no SF-36 foram observados em pacientes com níveis intermediário ou alto de atividade física, sobretudo nos domínios social (75 CI 57,3-92,6), saúde geral (75,5 CI 60,4-90,5), saúde mental (70 CI 57,8-82,1). CONCLUSÕES: A presença e a severidade do prejuízo no desempenho físico e dor não se associaram com Gh e IGF-1 no diagnóstico, tempo de exposição prévio à doença. Todavia, pacientes considerados controlados apresentaram melhores escores nos domínios físico e emocional, comparados com pacientes com hipersomatotrofismo persistente. Tais achados sugerem benefícios do controle metabólico na qualidade de vida.

Perfil microbiológico e desfechos clínicos de úlceras em pés de diabéticos internados / Microbiological profile and clinical outcome of severe foot ulcers of diabetic inpatients

Descrever o perfil microbiológico e os desfechos clínicos de úlceras graves em pés diabéticos de pacientes internados em um hospital universitário de atenção terciária no estado do Ceara, Brasil. Métodos: Conduziu-se uma análise retrospectiva de dados obtidos nos prontuários médicos de todos os pacientes diabéticos internados entre janeiro de 2006 a junho de 2007, nas enfermarias do Serviço de Endocrinologia e Diabetes do Hospital Universitário Walter Cantídio (Universidade Federal do Ceará), por úlceras graves em pés diabéticos, com no mínimo grau 2 da classificação de Wagner, refratárias ao tratamento ambulatorial. Dados clínicos (sexo, idade, tempo de diabetes e co-morbidades) de cada paciente assim como as características microbiológicas do material colhido das suas ulceras em pés ou das suas peças cirúrgicas (amputações) foram obtidos. Resultados: Foram identificados no período 17 diabéticos, todos tipo 2, com idade de 58,11±10,8 anos e 12,4±8,4 anos de doença, 58,8% homens. Das úlceras, 41,1% eram grau 2, 35,2% grau 3, 11,7% grau 4 e 11,7% grau 5 de Wagner, 64,7% com menos de 3 meses de evolução. Realizaram limpeza cirúrgica 82,3% dos pacientes e amputações 47%, sendo identificada osteomielite em 47% dos casos. Antibioticoterapia empírica foi iniciada em todos os pacientes, sendo ciprofloxacina/metronidazol o esquema mais usado (76,5%). Houve cultura negativa em 12,5% das realizadas. Nas positivas, os germes mais freqüentes foram: S. aureus (57,1%); S. viridans (28,7%); P. aeruginosas (28,7%) e M. morganii (28,7%) A maioria (75%) dos S. aureus isolados eram meticilino-resistentes, mas sensíveis à vancomicina. Conclusão: Observouse a presença de flora polimicrobiana com grande número de patógenos multirresistentes e elevada prevalência de osteomielite e amputações em diabeticos portadores de úlceras graves, neuropatia e doença vascular periférica.

To describe the microbiological profile and clinical outcomes of diabetic foot ulcers of inpatients of a tertiary university hospital, at Ceara, Brazil. Methods: We conducted a retrospective analysis of medical charts data of all diabetic inpatients of the Endocrine and Diabetes Unit of Walter Cantídio University Hospital (Federal University of Ceará), admitted from January, 2006 to June, 2007 for severe foot ulcers (minimum of grade 2 of Wagner`s classification), which were refractory to ambulatory treatment. Clinical data from each patient were recorded (sex, age, diabetes duration, and comorbidities) as well as microbiological characteristics of foot ulcers and surgical (amputations) material. Results: We identified 17 diabetic patients, all type 2, aged 58.11 ± 10.8 years and 12.4 ± 8.4 years of disease, 58.8% male. Of ulcers, 41.1% were grade 2; 35.2% grade 3; 11.7% grade 4 and 11.7% grade 5 of Wagner; 64.7% with less than 3 months of evolution. Debridement was performed in 82.3% of patients and amputation in 47%; osteomyelitis was identified in 47% of cases. All patients started empiric antibiotic therapy, where ciprofloxacin/metronidazole was the most used scheme (76.5%). Cultures were negative in 12.5% of the patients. In the positive ones, the most prevalent bacterial pathogens detected in the culture materials were: S. aureus (57.1%); S. viridans (28.7%); P. aeruginosas (28.7%); M. morganii (28.7%). The majority (75%) of isolated S. aureus were methicillin-resistant, but were sensitive to vacomicin. Conclusion: We observed the presence of polymicrobial flora with a large number of multiresistant pathogens and high prevalence of osteomyelitis and amputations in diabetic patients with severe ulcers, neuropathy and peripheral vascular disease.

Artroplastia infectada por fungos: análise secundária de dados / Fungus-infected arthroplasty: secondary data analysis

O objetivo desta pesquisa foi proceder à revisão sistemática, com análise secundária de dados dos relatos de casos de artroplastia com infecção rúngica, levantados dos bancos de dados Medline, Embase e Lilacs, entre 1966 e março de 2004. O número de publicaçÒes teve linha de tendência ascendente (R2 = 0,3593) no período estudado, sendo 68,9 por cento (n = 40) a partir de 1992. Dos 58 relatos de caso, o agente etiológico mais comum foi o gênero Candida (n = 51; 87,9 por cento) e na maioria a infecção foi em artroplastia do joelho (n = 29; 50 por cento). O tempo compreendido entre o aparecimento dos sintomas até o diagnóstico foi longo (média de 1,2 ano). Após a verificação da presença do fungo na cultura, a mesma só foi considerada verdadeira na primeira pesquisa em apenas 60por cento (n = 30) dos casos que continham a informação. Os casos restantes, inicialmente considerados falsos-contaminantes, só foram validados na segunda pesquisa micológica em 24por cento (n = 12), após uma terceira pesquisa em 14 por cento (n = 7), e até após uma quarta pesquisa em um caso (2 por cento). As revistas com linha editorial restrita à Ortopedia publicaram apenas 27 (46,5 por cento) casos, pouco mais do que os 34,5por cento (n = 20) relatados nas revistas de Infectologia. É provável que a incredulidade da presença do fungo ou o pouco interesse em relatar os casos, por parte dos ortopedistas sejam as causas do viés de diagnóstico e o conceito pré-formado de que a artroplastia infectada por fungos seja um evento improvável e raro
