In heart failure syndrome, myocardial dysfunction causes an increase in neurohormonal activity, which is an adaptive and compensatory mechanism in response to the reduction in cardiac output. Neurohormonal activity is initially stimulated in an attempt to maintain compensation; however, when it remains increased, it contributes to the intensification of clinical manifestations and myocardial damage. Cardiac remodeling comprises changes in ventricular volume as well as the thickness and shape of the myocardial wall. With optimized treatment, such remodeling can be reversed, causing gradual improvement in cardiac function and consequently improved prognosis.

This study aimed to estimate the resource consumption and societal impact of otitis media (OM) in children younger than five years of age in Portugal. An Internet survey on generic childhood symptoms and diseases was administered to a sample of parents. This self-report survey had been previously implemented in other European countries. Medically confirmed OM was defined as symptoms of earache or “running ear” and/or a diagnosis of OM provided by a medical doctor. Direct medical, nonmedical, and indirect nonmedical costs were calculated for individual cases. Mean total costs per OM episode were estimated at €334. This corresponds to an estimated societal impact of 72 million €/year, of which 39% were indirect nonmedical costs. An epidemiological study should help to confirm the results of this study, and evaluate whether an intervention to reduce the occurrence and/or duration of OM may have an impact on societal costs and quality of life for affected families.

ObjectiveTo assess Spanish and Portuguese patients’ and physicians’ preferences regarding type 2 diabetes mellitus (T2DM) treatments and the monthly willingness to pay (WTP) to gain benefits or avoid side effects.MethodsAn observational, multicenter, exploratory study focused on routine clinical practice in Spain and Portugal. Physicians were recruited from multiple hospitals and outpatient clinics, while patients were recruited from eleven centers operating in the public health care system in different autonomous communities in Spain and Portugal. Preferences were measured via a discrete choice experiment by rating multiple T2DM medication attributes. Data were analyzed using the conditional logit model.ResultsThree-hundred and thirty (n=330) patients (49.7% female; mean age 62.4 [SD: 10.3] years, mean T2DM duration 13.9 [8.2] years, mean body mass index 32.5 [6.8] kg/m2, 41.8% received oral + injected medication, 40.3% received oral, and 17.6% injected treatments) and 221 physicians from Spain and Portugal (62% female; mean age 41.9 [SD: 10.5] years, 33.5% endocrinologists, 66.5% primary-care doctors) participated. Patients valued avoiding a gain in bodyweight of 3 kg/6 months (WTP: €68.14 [95% confidence interval: 54.55–85.08]) the most, followed by avoiding one hypoglycemic event/month (WTP: €54.80 [23.29–82.26]). Physicians valued avoiding one hypoglycemia/week (WTP: €287.18 [95% confidence interval: 160.31–1,387.21]) the most, followed by avoiding a 3 kg/6 months gain in bodyweight and decreasing cardiovascular risk (WTP: €166.87 [88.63–843.09] and €154.30 [98.13–434.19], respectively). Physicians and patients were willing to pay €125.92 (73.30–622.75) and €24.28 (18.41–30.31), respectively, to avoid a 1% increase in glycated hemoglobin, and €143.30 (73.39–543.62) and €42.74 (23.89–61.77) to avoid nausea.ConclusionBoth patients and physicians in Spain and Portugal are willing to pay for the health benefits associated with improved diabetes treatment, the most important being to avoid hypoglycemia and gaining weight. Decreased cardiovascular risk and weight reduction became the third most valued attributes for physicians and patients, respectively.

Objectives: To estimate the short-term (1 year) cost-effectiveness of Insulin Detemir (IDet) compared with Neutral Protamine Hagedorn (NPH) insulin for Type 1 (T1DM) and Type 2 Diabetes Mellitus (T2DM) in Portugal. Methods:A short-term cost-effectiveness model was adapted to the Portuguese National Health System (NHS), to estimate the Incremental Cost-Effectiveness Ratio (ICER) of IDet vs. NPH in terms of euros per quality-adjusted life years (€/QALY) gained. Non-severe hypoglycemia (NSH) rate for both diabetes types, and weight change, only for T2DM, were the clinical benefit variables. Three scenarios were estimated in which NPH was assigned three different values corresponding to a cohort of recent insulinization and a cohort of long-run insulinization from the UK Hypoglycemia Study and from a Spanish observational study. For all scenarios, the hypoglycemia Rate Ratio (RR) for T1DM was based on the CADTH Technology Report while for T2DM it was based on the head-to-head NCT00104182 randomized clinical trial. For T2DM, weight gain was also included in the model, based on the same RCT. Disutility values to calculate quality-adjusted life years (QALYs) were associated to NSH events and to BMI unit gain. Costs (Euros 2014), estimated from the perspective of the Portuguese NHS, included only insulin treatment and mild hypoglycemia management. Results:For the three scenarios a range of 0.025 -0.076 QALYs for T1DM and 0.014 -0.051 QALYs for T2DM were gained for IDet vs. NPH due to NSH and weight gain avoidance, in return of an incremental cost of €159.38 -€248.98 for T1DM and €209.66 -€274.44 for T2DM. This resulted in IDet vs. NPH ICER ranging between €2,096.23 and €9,936.98/QALY for T1DM and €4,145.75 and €19,999.87/QALY for T2DM.Conclusions: IDet appears as a cost-effective alternative to NPH in Portugal for T1DM and T2DM in all considered scenarios due to lower hypoglycemic rate and less weight gain.

Fundamento: Estudos revelam que pacientes com insuficiência cardíaca (IC) e frequência cardíaca (FC) <70 batimentos por minuto (bpm) evoluem melhor e têm menor morbimortalidade em comparação com FC >70. Entretanto, muitos pacientes com IC mantêm FC elevada.Objetivo: Avaliar se os pacientes acompanhados em ambulatório de cardiologia têm sua FC controlada e como estava a prescrição dos medicamentos que reduzem a mortalidade na IC. Métodos: Foram analisados de forma consecutiva pacientes que passaram em consulta e que já acompanhavam em ambulatório de cardiologia, idade > 18 anos e com diagnóstico de IC e fração de ejeção do ventrículo esquerdo (FEVE) <45%. Os pacientes em ritmo sinusal foram divididos em dois grupos: FC ≤70 bpm (G1) e FC >70 bpm (G2). Na análise estatística, foram utilizados os testes t de Student, Qui-quadrado. Foi considerado significante p <0,05. Utilizamos o programa Statistical Package for the Social Sciences (SPSS) para análise. Resultados: Foram avaliados 212 pacientes de forma consecutiva. Destes, 41 (19,3%) apresentavam fibrilação atrial ou eram portadores de marca-passo e foram excluídos desta análise; assim, 171 pacientes foram analisados. Os pacientes em ritmo sinusal tinham idade média de 63,80 anos (±11,77), sendo 59,6% homens e FEVE média de 36,64% (±7,79). Com relação à etiologia, a isquêmica estava presente em 102 pacientes (59,65%), enquanto a cardiopatia chagásica em 17 pacientes (9,9%); 131 pacientes eram hipertensos (76,6%), enquanto 63 pacientes (36,84%) eram diabéticos. Quanto à FC, 101 pacientes apresentaram FC ≤70 bpm (59,06%) G1 e 70 pacientes (40,93%) FC >70 bpm (G2). A FC média no G1 foi de 61,53 bpm (±5,26) e no G2, 81,76 bpm (±9,52), p <0,001.A quase totalidade dos pacientes (98,8%) estava sendo tratada com carvedilol prescrito na dose média de 42,14 mg/dia (±18,55) no G1 versus 42,48 mg/dia (±21,14) no G2, p=0,911. A digoxina foi utilizada em 5,9% dos pacientes no G1 versus 8,5% no G2, p=0,510. A dose média de digoxina no G1 foi de 0,19 mg/dia (±0,06) e no G2 foi de 0,19 mg/dia (±0,06), p=0,999. A maioria dos pacientes (87,72%) utilizou o inibidor da enzima de conversão da angiotensina (IECA) ou bloqueador do receptor da angiotensina (BRA), e 56,72% utilizaram espironolactona. A dose média de enalapril foi de 28,86 mg/dia (±12,68) e de BRA foi de 87,80 mg/dia (±29,80). A maioria dos pacientes utilizou IECA ou BRA e com doses adequadas. Conclusão: O estudo revelou que 40,93% dos pacientes estavam com FC acima de 70 bpm, apesar de o betabloqueador ter sido prescrito para praticamente todos os pacientes e em doses elevadas. Outras medidas precisam ser adotadas para manter a FC mais controlada nesse grupo de frequência mais elevada.
