Reverse Auction: A Potential Strategy for Reduction of Pharmacological Therapy Cost

Background:Polypharmacy is a significant economic burden.Objective:We tested whether using reverse auction (RA) as compared with commercial pharmacy (CP) to purchase medicine results in lower pharmaceutical costs for heart failure (HF) and heart transplantation (HT) outpatients.Methods:We compared the costs via RA versus CP in 808 HF and 147 HT patients followed from 2009 through 2011, and evaluated the influence of clinical and demographic variables on cost.Results:The monthly cost per patient for HF drugs acquired via RA was $10.15 (IQ 3.51-40.22) versus $161.76 (IQ 86.05‑340.15) via CP; for HT, those costs were $393.08 (IQ 124.74-774.76) and $1,207.70 (IQ 604.48-2,499.97), respectively.Conclusion:RA may reduce the cost of prescription drugs for HF and HT, potentially making HF treatment more accessible. Clinical characteristics can influence the cost and benefits of RA. RA may be a new health policy strategy to reduce costs of prescribed medications for HF and HT patients, reducing the economic burden of treatment.

Correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas de "coast cross nº 1" e a análise física e química de um latossol vermelho amarelo: I. Concentrações de nutrientes nas folhas em função das frações granulométricas do solo

Foi realizado um levantamento em 41 áreas de um solo classificado como Latossol Vermelho Amarelo, com amostragens de solo e de folhas da forrageira "Coast Cross nº 1" objetivando o estudo de correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas e as análises físicas do solo. Os autores observaram que a concentração de potássio nas folhas correlaciona-se negativamente com a fração silte do solo. A concentração de cobre nas folhas correlaciona-se negativamente com a fração areia fina e positivamente com argila. Ferro, manganês, zinco, sódio, boro e alumínio não apresentam correlações entre as suas concentrações foliares e os teores de argila no solo.

Correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas de "Coast Cross nº 1" e a análise física e química de um Latossolo vermelho amarelo II: Concentração de nitrogênio e fósforo

Foi realizado um levantamento em 41 pontos de um Latossolo Vermelho Amarelo, com amostragem de solo e folhas da forrageira "Coast Cross Nº 1", objetivando o estudo de correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas e as análises químicas do solo. As folhas foram secas e analisadas para N, P. As amostras de solo foram secas e analisadas pelos seguintes métodos: índices pH (água e CaCl2 0,01 M), matéria orgânica (digestão úmida) , P, K, B, Cu, Fe, Mn, Zn e Na pelo extrator de Mehlich. P através de resina iônica. Ca, Mg e Al pelo KC1 1 N. As frações granulométricas foram dispersas por NaOH 0,1 Ne separadas pelo método da pipeta. Foram observadas correlações entre as concentrações de elementos nas folhas e as determinações no solo. Nitrogênio nas folhas correlacionou-se negativamente com fósforo do solo e positivamente com manganês e enxofre. Fósforo nas folhas correlacionou-se negativamente com cálcio do solo.

Cross-infection experiments with "isospora" of cats and dogs

Feces of 34 dogs out of 251 (13.5%) from guanabara were positive for Isospora. From these 19 (7.5%) were i. rivolta, 13 (5.2%) were I. canis and 2 (0,7) were i. bigemina. "Free-sporocysts" of I. rivolta were eliminated by 9 dogs (3.5%). A "Caryospora-like" oocyst was seen once. Cross-infection experiments performed with Isospora from dogs and cats failed to produce infection while inoculations of these Isospora in their natural hosts succeeded. The results suggest that the species of Isospora occurring in cats are different from those of dogs.

Cross-suppression of specific immune responses after oral tolerance

Adult normal inbred mice rendered tolerant to OVA by previous oral exposure do not respond to intraperitonela immunization with DNP-OVA in adjuvant. These tolerant mice also form less DNP-specific antibodies to DNP-KLH when immunized with mixtures of DNP-KLH and DNP-OVA, or less HGG-specific antibodies when immunized with cross-linked conjugates of OVA and HGG. These same procedures increased DNP-specific or HGG-specific responses in non-tolerant control mice. The cross-supperssion was ineffective, however, to inhibit already ongoing antibody responses.

Relationship of physical activity with motor skills, aerobic fitness and body fat in preschool children: a cross-sectional and longitudinal study (Ballabeina).

Adiposity, low aerobic fitness and low levels of activity are all associated with clustered cardiovascular disease risk in children and their high prevalence represents a major public health concern. The aim of this study is to investigate the relationship of objectively measured physical activity (PA) with motor skills (agility and balance), aerobic fitness and %body fat in young children. This study is a cross-sectional and longitudinal analyses using mixed linear models. Longitudinal data were adjusted for baseline outcome parameters. In all, 217 healthy preschool children (age 4-6 years, 48% boys) participated in this study. PA (accelerometers), agility (obstacle course), dynamic balance (balance beam), aerobic fitness (20-m shuttle run) and %body fat (bioelectric impedance) at baseline and 9 months later. PA was positively associated with both motor skills and aerobic fitness at baseline as well as with their longitudinal changes. Specifically, only vigorous, but not total or moderate PA, was related to changes in aerobic fitness. Higher PA was associated with less %body fat at baseline, but not with its change. Conversely, baseline motor skills, aerobic fitness or %body fat were not related to changes in PA. In young children, baseline PA was associated with improvements in motor skills and in aerobic fitness, an important determinant of cardiovascular risk.

A cross-sectional survey of attitudes to HIV risk and rapid HIV testing among clients of sex workers in Switzerland.

OBJECTIVES: To assess attitudes to HIV risk and acceptability of rapid HIV testing among clients of street-based female sex workers (FSW) in Lausanne, Switzerland, where HIV prevalence in the general population is 0.4%. METHODS: The authors conducted a cross-sectional study in the red light district of Lausanne for five nights in September of 2008, 2009 and 2010. Clients of FSW were invited to complete a questionnaire in the street assessing demographic characteristics, attitudes to HIV risk and HIV testing history. All clients interviewed were then offered anonymous finger stick rapid HIV testing in a van parked on-site. RESULTS: The authors interviewed 112, 127 and 79 clients in 2008, 2009 and 2010, respectively. All were men, average age 32-37 years old; 40-60% were in a stable relationship. History of unprotected sex was higher with non-commercial partners (33-50%) than with FSW (6-11%); 29-46% of clients had never undergone an HIV test. Anonymous rapid HIV testing was accepted by 45-50% of clients. Out of 109 HIV tests conducted during the three study periods, none was reactive. CONCLUSIONS: On-site HIV counselling and testing is acceptable among clients of FSW in this urban setting. These individuals represent an unquantified population, a proportion of which has an incomplete understanding of HIV risk in the face of high-risk behaviour, with implications for potential onward transmission to non-commercial sexual partners.
