To the Editor.— Two recent reviews in Pediatrics1,2 provide much interesting information on the effect of home visits on the health of women and children. However, I was disappointed not to find in either article more than token reference to the cost of the programs reviewed. In this day of increasingly scarce health care resources, we no longer have the luxury of evaluating programs such as these without detailed consideration of their cost-benefit ratio.

AbstractThe authors review the main concepts regarding the importance of cleaning/disinfection of ultrasonography probes, aiming a better comprehension by practitioners and thus enabling strategies to establish a safe practice without compromising the quality of the examination and the operator productivity. In the context of biosafety, it is imperative to assume that contact with blood or body fluids represents a potential source of infection. Thus, in order to implement cleaning/disinfection practice, it is necessary to understand the principles of infection control, to consider the cost/benefit ratio of the measures to be implemented, and most importantly, to comprehend that such measures will not only benefit the health professional and the patient, but the society as a whole.

AbstractThe costs and benefits of vaccinating troops on United Nations tours in Yugoslavia against hepatitis A were compared. The marginal cost of one case of hepatitis A avoided by vaccination was calculated and compared with the marginal cost of achieving the same outcome by passive immunization. The cost-benefit ratio (medium estimate) for troops at low risk of contracting hepatitis A was 0.01 and for those at high risk was 0.03.Vaccinating troops against hepatitis A for a single deployment appears to be an inefficient procedure, especially in troops at low risk. However, in professional troops from countries of low hepatitis A endemicity who are likely to be involved in several operational deployments, vaccination becomes more efficient the more times the same troops are deployed.

The present study makes a comparative analysis of the cost-benefit ratio between Conventional Concrete (CC) and High Performance Concrete (CAD). To obtain the consumption rates of concrete, steel and shape of each case, two studies of the same structure were carried out, changing only one variable: the characteristic strength of concrete to compression (fck). In the first case, the 25 Megapascal fck (MPa) representing the CC was applied, and in the second case, 50 MPa fck corresponding to the CAD. For analysis of the structural elements, the Cypecad Software was used. It was found that one of the initial hypotheses, that the consumption of concrete, steel and form would decrease with the use of CAD, was confirmed. The second hypothesis, that the CAD would be more financially advantageous than the CC, was not confirmed, but factors that may have led to this non-confirmation were pointed out.

Background: Sperm sexing is increasing in use because pre-determining the sex of the calf allows greater profitability and promotes significant gains in the productive systems that utilize the technique. Deployment of a low-cost and practical preservation methodology may further favor the cost-benefit ratio. Flow cytometry, the most commonly used sexing technique, has high costs and is very restricted. As an alternative, immunosexing has been studied, which uses sex-specific monoclonal antibodies. Thus, the objective of this study was to evaluate the immunosexing technique in conjunction with cryopreservation in ACP-102c and examine its economic aspects with regard to ram semen.Materials, Methods & Results: Ejaculates from two ram individuals were collected with the aid of an artificial vagina, evaluated, and submitted to the immunosexing protocol, according to the manufacturer's recommendations, using the Monoclonal Antibody Kit specific for mammalian sperm with “Y” chromosomes (HY; HY Biotechnology, Rio de Janeiro-RJ, Brazil). After sexing, the supernatant was resuspended in the cryopreservation diluent: ACP (ACP-102c + 20% egg yolk + 7% glycerol), packaged in 0.25 mL straws, refrigerated to 4°C, stabilized for 30 min, frozen in liquid nitrogen vapors (-60°C) for 15 min, immersed in liquid nitrogen, and stored in cryogenic cylinders. The samples were thawed and evaluated for sperm kinetics both by using computerized semen analysis with SCA® software (Sperm Class Analyzer version 5.0) and subjectively comparing specimens from the two animals using conventional microscopy (40x). Plasma membrane integrity (IMP) and sperm cell morphology were evaluated by the smear staining technique using eosin-nigrosine dye, and the percentages of healthy and normal spermatozoa were determined. A bibliographic survey and a market study of similar products and technologies were carried out to provide an economic viability metanalysis of the bioproduct (ACP-102c) and bioprocess (immunosex). The data were analyzed using R-project©, and comparisons made between animals and between thawing periods using T test. There were no statistically significant differences between animals and between periods (P > 0.05), except for the normal sperm parameter, in which animal A1 had the lowest percentage (P < 0.05). As for the cost-benefit ratio, flow cytometry as a technique is more laborious and expensive, while immunosexing associated with cryopreservation in ACP-102c diluent has proven more practical, with regards to both sperm sexing techniques and diluents for sperm conservation.Discussion: In general, the quality of cryopreserved sexed semen was lower than that of non-sexed semen; however, in this study, both in the comparison between animals and between evaluation periods, similar values of motility, viability, and sperm morphology were obtained for sexed and several non-sexed cryopreserved semen samples, demonstrating that immunosexing did not severely affect the sperm structure, and that the ACP-102c conservation medium was efficient at maintaining the plasma membrane of these sperm. In the evaluation of economic aspects, it was observed that immunosexing, associated with cryopreservation in ACP-102c diluent, proved to be the most practical technique, requiring only conventional equipment, and allowing a greater field of application, since the immunosexing semen can be used for primiparous and multiparous females. Thus, it was concluded that immunosexing associated with cryopreservation in an ACP-102c diluent was more cost-effective, more practical, and had significantly improved sperm quality results after sexing.
