Decision-Making in Mastitis Prevention and Control at Regional, Herd and Individual Levels Based on Epidemiological and Economic Studies

The objective of this review is to describe results of epidemiological and economic studies carried out in Brazil that can assist in the decision making process at the region, herd and individual levels for the prevention and control of bovine mastitis. At regional and herd-levels, we present data from a time series analysis comparing somatic cell counts in herds located in Brazil and in the United States (US), an estimation of the prevalence of contagious mastitis pathogens in a specific population of herds located at the state of Minas Gerais, and finally we report the identification of risk factors for new and chronic intramammary infections within herds located at the state of Santa Catarina. The outcomes of epidemiological studies that support the decision making process at herd- and individual-level are related to the decrease in prevalence of contagious mastitis pathogens in the herd as well as the estimate of the economic impact of mastitis occurrence.

Beneficial Effects of Vitamin E against Indomethacin-induced Glutathione Depletion, Acetylcholinesterase Activity, (Na+,K+)-ATPase Activity and Osmotic Fragility of Erythrocyte

Indomethacin, is a well-known non-steroidal anti-inflammatory drug (NSAID), a cyclooxygenase inhibitor and extensively used as a medicine to reduce pain, fever, stiffness, swelling or inflammatory responses. Indomethacin inhibits both COX-1 and COX-2, which in turn, inhibits the production of prostaglandins in the gastrointestinal tract and disrupts the mucosal lining in the gastrointestinal tract leading to intestinal bleeding and perforation.

Urinary Tract Endometriosis: Case Reports

The incidence of urinary tract endometriosis ranges from 0.3 to 12% of all women affected by endometriosis. Endometriosis has been successfully treated at General Surgery Department of National Medical Research Center of Obstetrics, Gynecology and Perinatology named after V.I. Kulakov in Moscow. In the 2012-2016 period, we performed 23 bladder resections, ureterolysis in 35 patients, 3 ureteral resections with reimplantations, 3 ureteral resections and uretero-ureteral anastomosis. All these procedures were performed for urinary tract endometriosis. We present 2 cases of urinary tract endometriosis in women of reproductive age. The possibilities of hormonal therapy in the treatment of endometriosis are limited. Surgical intervention with complete removal of endometrial tissue is the most effective; however, the probability of recurrence still remains high, especially in young patients.

His Bundle Pacing: Short Review of Literature and Technical Aspects

History of pacing has evolved from the primitive state of temporary transvenous pacing by a large fixed machine to leadless modern technology. The pacing site has also been changed from traditional right ventricular apex to various other sites. The concept behind such experiment was due to several complications in the long term from traditional Right Ventricular Apical Pacing (RVAP). The His Bundle pacing results in conduction and contraction similar to and more often called physiological pacing. This mini-review describes the short history of the evolution of the concept of His Bundle pacing and its technical aspects of successful implantation.

Novel Multi-Functional Dental Cement for Enamel Remineralization and AntiCariogenic Bacteria Activity

This experimental study evaluated the release of fluoride and several minerals related to remineralization from novel functional cement, apatite ionomer cement (AIC), and its anti-bacterial properties compared with glass ionomer cement (GIC) and surface pre-reacted glass-ionomer filler containing composite resin (giomer). Conventional GIC (Fuji III, GC Co., Tokyo, Japan) was used as the control and fundamental materials. In the AIC powder, 28% wt of GIC powder was replaced with spherical-shaped hydroxyapatite powder. The giomer, BeautiSealant (Shofu Co., Kyoto, Japan), was used as a positive control. Each specimen was immersed in deionized water and analyzed by inductively coupled plasma atomic emission spectrometry (for Al, Si, P, Ca and Sr) and a fluoride-selective electrode. Antibacterial activity against Streptococccus mutans was evaluated using the adenosine-5’-triphosphate luminescence method. Concentrations of released ions from AIC specimens were significantly higher than those from GIC and giomer specimens. Regarding antibacterial activity, luminescence intensity of the AIC group was significantly lower than that of the control and giomer groups. It was concluded that AIC could be a most suitable material for pit and fissure sealant for enamel remineralization and anti-cariogenic and -bacterial activity.
