Retrospective study of histopathological grades of mammary neoplasms in domestic bitches

The epidemiological and clinicopathological characteristics of mammary neoplasms in domestic bitches are valuable information to analyze the behavior of the disease and are a potential resource to promote advances in mammary neoplasms. The objective of this research work was to evaluate and analyze the classification of histopathological grades in the various mammary neoplasms in domestic bitches and to identify possible risk factors such as age, breed, nutrition and lack of sterilization and how these factors influence in the appearance of mammary neoplasms and the survival time of the patients. The most frequent tumors were complex adenoma, benign mixed tumor, complex carcinoma, and mixed-type carcinoma. The most frequently affected breeds were the Poodle, Cocker Spaniel, Yorkshire Terrier, German Shepherd and only the Cocker, with the Labrador showing the highest risk. In general, the data indicate that mammary neoplasms mainly affect entire females, adults older than 8 years of different races; It presents with high mortality and short survival in patients with a large malignant tumor; however, the most affected breeds are not necessarily the most predisposed. Furthermore, feeding factors and early sterilization do not play an important role in the presence of mammary neoplasms in domestic bitches.

Comorbidity of overweight and obesity in dogs and cats

Overweight and Obesity are the most common nutritional diseases in dogs and cats. The big difference between overweight in pets and humans is that animals do not have the ability to control their weight. They depend solely and exclusively on what their owner serves them. From one year of age it is essential to provide them with the recommended diet for their age, species and breed. Otherwise, we will lead them to become overweight, and from there to obesity. Obesity is defined as excess body fat sufficient to cause disease. When the animal consumes more calories than it expends, fat accumulates in the body. In dogs, overweight begins when the animal exceeds between 15 and 30% the weight established as normal for the breed. Above 30%, we would be talking about obesity. In the case of cats, they are considered overweight when they exceed their “ideal weight” by more than 10%, and they are considered obese when they exceed it by 20%. Health and longevity are affected by excessive fat deposits in the body. Diseases associated with obesity and overweight include traumatic or degenerative orthopedic disorders, cardiovascular disease manifesting with congestive heart failure, exercise and heat intolerance, predisposition to diabetes mellitus, hypertension, hyperlipidemia, transitional cell carcinoma of the bladder. and compromised immune function. On the other hand, obesity and overweight increase the risk of suffering from breast tumors, and this is related not only to obesity but also to the consumption of homemade food and red meat. This bibliographic review of literature seeks to gather and summarize scientific, updated and specific information about the pathologies that are associated with overweight and obesity in dogs and cats, with the aim of understanding the physiology of the pathology and how the Medical professional A veterinarian can intervene in a timely manner to control these disorders associated with pet nutrition.

Simulation of fire outbreaks in polyurethane footwear warehouses using inorganic fire retardants

Introduction: currently, a significant increase has been observed in the number of fires that especially affect commercial footwear stores, without effective preventive measures being adopted to reduce possible losses. A simulation of a polyurethane footwear warehouse was carried out using the Consolidated Model of Fire and Smoke Transport (CFAST) software and the SmokView smoke viewer. To have a point of comparison, the fire scenario was first modeled without implementing any prevention or control measures. Then, a second fire scenario was simulated by designing a water sprinkler system in the enclosure room with the highest thermal load following the UNE 12845 standard and the NFPA 13 standard. Afterwards, to check the effectiveness of the smoke removal and the temperature of the fire in the premises, an inorganic fire retardant based on Mg (OH)2 was used in the feed water of the Sprinklers system, modifying the Heat Growth Curve (CCC) by 18%. Objectives: The objectives of the study were to evaluate the effectiveness of different fire mitigation strategies in a footwear warehouse through simulations with CFAST software, identifying innovative technologies to reduce firepower release (HRR) and optimize fire activation times. suppression systems. Methodology: The fire simulation was carried out using the CFAST software, considering the environmental conditions of the city of Ambato and the thermodynamic properties of the materials in the footwear warehouse. A water Sprinkler system was designed according to NFPA 13 and UNE 12845 regulations. In addition, the effect of the inorganic fire retardant based on Mg (OH)2 on the Sprinkler system was evaluated. Results: the results indicate a smoke saturation time of 1510sec and an enclosure temperature of 34°C at 34sec without a fire protection system. In the simulation of a water-based firefighting system, the following were determined: a) the smoke saturation time in all rooms at 67 seconds, b) the time necessary to cool the room was 1500 seconds. to reach 34°C. Finally, the fire simulation using the fire retardant reduced the cooling time of the room by 22.56% until it reached a cold temperature of 35 °C. The simulation was carried out for the city of Ambato, at an altitude of 2560 m, with a temperature of 16 °C, a pressure of 97172.02 for a relative humidity of 65% and a limit amount of oxygen of 15%. Conclusions: The implementation of fire mitigation strategies, such as the use of water sprinkler systems and the use of inorganic fire retardants, can significantly reduce response times in the event of a fire and minimize the risk of material and human losses in commercial establishments. footwear. It is crucial to consider the technical effectiveness and economic viability of these measures to promote their adoption into local regulations and improve fire safety throughout the commercial sector.
