Governor's Task Force on Efficiencies and Cost-Effectiveness in Iowa State Government,Final Report, December 1983

A special task force was formed and worked through its various committees to uncover and investigate possible areas for cutting costs and saving money in State Government operations. A total of 81 recommendations are made in this report, with potential savings of over $32 million during the next several years.

Critical appraisal of single port access cholecystectomy.

BACKGROUND: Single port access (SPA) cholecystectomy is a new concept in laparoscopic surgery. A review of existing results was performed to evaluate critically the current state of SPA with specific reference to feasibility, safety, learning curve, indications and cost-effectiveness. METHODS: All papers identified in MEDLINE until 15 February 2010 and all other relevant papers obtained from cited references were reviewed, without any language restriction. Case reports and series of fewer than three patients were excluded. RESULTS: After selection, 24 studies including 895 patients were analysed. None was randomized. Feasibility seems to be established, with a conversion rate of 2 per cent. SPA was not standardized and there was much technical variation. The learning curve could not be determined. Median follow-up time was 3 (range 0.25-12) months. The overall published complication rate was 5.4 per cent and the biliary complication rate 0.7 per cent. The rate of umbilical complications ranged from 2 to 10 per cent. CONCLUSION: SPA cholecystectomy seems feasible, but standardization, safety and the real benefits for patients need further assessment. Uncontrolled wide adoption of this approach may be responsible for a rise in biliary complications.

Optimal public rationing and price response.

We study optimal public health care rationing and private sector price responses. Consumers differ in their wealth and illness severity (defined as treatment cost). Due to a limited budget, some consumers must be rationed. Rationed consumers may purchase from a monopolistic private market. We consider two information regimes. In the first, the public supplier rations consumers according to their wealth information (means testing). In equilibrium, the public supplier must ration both rich and poor consumers. Rationing some poor consumers implements price reduction in the private market. In the second information regime, the public supplier rations consumers according to consumers' wealth and cost information. In equilibrium, consumers are allocated the good if and only if their costs are below a threshold (cost effectiveness). Rationing based on cost results in higher equilibrium consumer surplus than rationing based on wealth.

Génériques des médicaments antiépileptiques [Generics of antiepileptic drugs]

Generic substitution of antiepileptic drugs (EAD) have limited use because epilepsy is a chronic disease, seizure recurrence has an important impact of the quality of life and the potential risk of accidents. EADs have a narrow therapeutic window, non negligible side effects and complex interactions. Bioavailability of generic EADs, tested in healthy men during a limited period of time must be within the 90% IC, in which means that serum levels can range from 80% to 125% of the original drug. A slight drop in serum level could increase the risk of seizure recurrence, as indicated by several publications. Although no formal studies regarding cost effectiveness and the rate of seizure recurrence is available yet, the prevailing consensus recommends not to replace an original antiepileptic drug by a generic, due to the harmful risk of seizure recurrence.

Detecció de matrícules amb sistemes de baix cost

En aquest projecte s'avaluen els mètodes utilitzats per els mecanismes de detecció de matrícules, i es proposarà un algorisme de detecció de matrícules dissenyat específicament per a sistemes de baix cost com ara els ordinadors actuals. Utilitzarem eines al nostre abast, com càmeres fotogràfiques domèstiques o de mòbil per analitzar el rendiment de l'algorisme

Spare non-occupational HIV post-exposure prophylaxis by active contacting and testing of the source person.

OBJECTIVE: HIV-1 post-exposure prophylaxis (PEP) is frequently prescribed after exposure to source persons with an undetermined HIV serostatus. To reduce unnecessary use of PEP, we implemented a policy including active contacting of source persons and the availability of free, anonymous HIV testing ('PEP policy'). METHODS: All consultations for potential non-occupational HIV exposures i.e. outside the medical environment) were prospectively recorded. The impact of the PEP policy on PEP prescription and costs was analysed and modelled. RESULTS: Among 146 putative exposures, 47 involved a source person already known to be HIV positive and 23 had no indication for PEP. The remaining 76 exposures involved a source person of unknown HIV serostatus. Of 33 (43.4%) exposures for which the source person could be contacted and tested, PEP was avoided in 24 (72.7%), initiated and discontinued in seven (21.2%), and prescribed and completed in two (6.1%). In contrast, of 43 (56.6%) exposures for which the source person could not be tested, PEP was prescribed in 35 (81.4%), P < 0.001. Upon modelling, the PEP policy allowed a 31% reduction of cost for management of exposures to source persons of unknown HIV serostatus. The policy was cost-saving for HIV prevalence of up to 70% in the source population. The availability of all the source persons for testing would have reduced cost by 64%. CONCLUSION: In the management of non-occupational HIV exposures, active contacting and free, anonymous testing of source persons proved feasible. This policy resulted in a decrease in prescription of PEP, proved to be cost-saving, and presumably helped to avoid unnecessary toxicity and psychological stress.

Constraint and cost of oxidative stress on reproduction: correlative evidence in laboratory mice and review of the literature.

ABSTRACT: BACKGROUND: One central concept in evolutionary ecology is that current and residual reproductive values are negatively linked by the so-called cost of reproduction. Previous studies examining the nature of this cost suggested a possible involvement of oxidative stress resulting from the imbalance between pro- and anti-oxidant processes. Still, data remain conflictory probably because, although oxidative damage increases during reproduction, high systemic levels of oxidative stress might also constrain parental investment in reproduction. Here, we investigated variation in oxidative balance (i.e. oxidative damage and antioxidant defences) over the course of reproduction by comparing female laboratory mice rearing or not pups. RESULTS: A significant increase in oxidative damage over time was only observed in females caring for offspring, whereas antioxidant defences increased over time regardless of reproductive status. Interestingly, oxidative damage measured prior to reproduction was negatively associated with litter size at birth (constraint), whereas damage measured after reproduction was positively related to litter size at weaning (cost). CONCLUSIONS: Globally, our correlative results and the review of literature describing the links between reproduction and oxidative stress underline the importance of timing/dynamics when studying and interpreting oxidative balance in relation to reproduction. Our study highlights the duality (constraint and cost) of oxidative stress in life-history trade-offs, thus supporting the theory that oxidative stress plays a key role in life-history evolution.
