BackgroundAssessment of the efficiency of interventions is paramount to achieving equitable health-care systems. One key barrier to the widespread use of economic evaluations in resource allocation decisions is the absence of a widely accepted method to define cost-effectiveness thresholds to judge whether an intervention is cost-effective in a particular jurisdiction. We aimed to develop a method to estimate cost-effectiveness thresholds on the basis of health expenditures per capita and life expectancy ...

We measured the temporal relationship between weight recovery, expression of hypothalamic‐opioid activity and pituitary GnRH responsiveness, and resumption of ovulatory cycles. DESIGN Five patients with anorexia nervosa were prospectively studied during ...

The combined processes; rapid solidification, addition of Cu3P compound and heat treatments to improve the mechanical properties of the hypereutectic Al-13Si, Al-20Si and Al-20Si-1.5Fe-0.7Mn alloys (in wt. %) was studied. Optical microscopy and scanning electron microscopy were used to characterize the microstructures. The mechanical properties were evaluated by tensile tests. It was found that the cooling rate (20-50°C/s) used to solidify the alloys plus the addition of Cu3P compound favored the formation ...

New local/regional climatic data were compared with floral and faunal records from central Patagonia to investigate how faunas evolve in the context of local and global climates. Oxygen isotope compositions of mammal fossils between c. 43 and 21 Ma suggest a nearly constant mean annual temperature of 16 ± 3 °C, consistent with leaf physiognomic and sea surface studies that imply temperatures of 16–18 °C. Carbon isotopes in tooth enamel track atmospheric δ13C, but with a positive deviation at 27.2 Ma, ...

Political participation has frequently been associated with individual resources; that is, individuals with higher incomes, higher educational levels and more time tend to participate in the political process to a greater extent than other individuals do. The present study suggests that in addition to resources, an individual's beliefs about economic distribution are an important determinant of participation both in elections and in protests.

The judicious use of cis-Pt as an intravenously administrable Pt(II) drug for chemotherapy requires the evaluation of its interactions with blood proteins. Therefore, the combined use of modern analytical chemical speciation and of analytical proteomics approaches to study these interactions is described here. The method involves incubation of cis-Pt with standard proteins and human serum samples. The separation of the proteins is conducted by liquid chromatography in an anion exchange column (Mono ...

BACKGROUND AND OBJECTIVE Male pseudohermaphroditism due to 5α‐reductase deficiency was originally described in 1974. Recently, 5α‐reductase Type 2 gene defects have been found generally to be due to point mutations within the 5 exons of the 5α‐reductase‐2 gene. In this report, we describe the molecular study of patients with 5α‐reductase deficiency. DESIGN Previously diagnosed patients with 5α‐reductase deficiency were sampled in order to perform molecular studies. PATIENTS Eight 5α‐reductase deficient ...

The aim of this study was to compare 5-year cost-effectiveness and clinical outcomes of patients with oral rapamycin (OR) plus bare-metal stent versus the drug-eluting stent (DES) strategy. During 2006 to 2007, a total of 200 patients were randomized to OR (n = 100) and DES (n = 100). Primary end point was to compare costs of initial procedure and cost-effectiveness of both revascularization strategies. Safety was evaluated by the composite of death, myocardial infarction, and cerebrovascular accident. ...

Numerous proposals have been presented in recent years to tackle particular aspects of the working pipeline towards creating a functional end-to-end system, such as object detection, tracking, path planning, sentiment or intent detection, amongst others. Nevertheless, few efforts have been made to systematically compile all of these systems into a single proposal that also considers the ...

Epidemiological and decision models are important tools to estimate disease burden. The purpose of this study was to identify models to assess the burden of diseases attributable to SSBs consumption or the potential impact of health interventions. Methods We carried out a systematic review and literature search up to August 2018. Pairs of reviewers independently selected, ...

BackgroundWorldwide, smoking tobacco causes 7 million deaths annually, and this toll is expected to increase, especially in low-income and middle-income countries. In Latin America, smoking is a leading risk factor for death and disability, contributes to poverty, and imposes an economic burden on health systems. Despite being one of the most effective measures to reduce smoking, tobacco taxation is underused and cigarettes are more affordable in Latin America than in other regions. Our aim was ...
