Difficult intubation, inadequate ventilation and esophageal intubation are the principal causes of death or brain damage related to airway manipulation. The objective of this cross-sectional study was to correlate a preanesthetic evaluation that may be capable of predicting a difficult intubation with the conditions encountered at laryngoscopy and endotracheal intubation. Eighty-one patients submitted to general anesthesia were evaluated at a preanesthetic consultation according to the modified Mallampati classification, the Wilson score and the American Society of Anesthesiologists (ASA) difficult airway algorithm. Findings were then correlated with the Cormack-Lehane classification and with the number of attempts at endotracheal intubation. No statistically significant correlations were found between the patients’ Mallampati classification and their Cormack-Lehane grade or between the Mallampati classification and the number of attempts required to achieve endotracheal intubation. Laryngoscopy proved difficult in four patients and in all of these cases the Wilson score had been indicative of a possibly difficult airway, highlighting its good predicting sensitivity. However, the specificity of this test was low, since another 24 patients had the same Wilson score but were classified as Cormack-Lehane I/II. Moreover, two patients who had a Wilson score ≥ 4 were also classified as Cormack-Lehane grade I/II. The study concluded that the Wilson score, although seldom used in clinical practice, is a highly sensitive predictor of a difficult airway;its specificity, however, is low.

Several studies argue that an ideal biomaterial for urinary catheters is utopian. Based in literature review it seems to be true. However, research advances: the biomaterial itself, new designs, new coatings, associated drugs, etc. Once implanted and interacting with urine, two old problems persist: encrustation and bacterial colonization. In this context, an extracellular product from bacterial synthesis on sugarcane molasses biomaterial has been studied in several experimental and clinical studies. Based on its high biocompatibility, the aim of this study is to evaluate its performance in an in vivo model as an endourologic prosthesis implanted in the bladder of Wistar rats. We evaluate physical, chemical and biological phenomena in comparison to an already established biomaterial, polyurethane. Even though it is not a finished product, the sugarcane biopolymer presented similar performance compared to polyurethane in several analyzed parameters and has an important characteristic: low cost.

Cats Infected by Feline Leukemia Virus—Morpho-Quantitative Evaluation of the Thymus

引用

Open Journal of Animal Sciences 2015年第3期5卷 277-282页

The feline leukemia virus (FeLV) is a complex disease that affects mainly the immune and hematological systems of cats. And because the thymus was closely associated with the immune system, the aim of this study was to quantify the morphological changes in the thymus of naturally infected and uninfected animals. Thymus morphological changes were evaluated by quantifying the following parameters: thymocytes, fat tissue, thymic corpuscles, connective tissue, and type I and III collagen. This study analyzed a total of seven cats, five in the negative group (Fn) and two in the positive (Fp) group. The areas occupied by thymocytes in FeLV negative (Fn) and positive (Fp) animals were, respectively, 55.16% ± 6.15% and 44.81% ± 6.15% (p = 0.39);adipocytes, 42.14% ± 5.97% (Fn) and 53.42% ± 11.3% (Fp) (p = 0.34);blood vessels, 0.85% ± 0.24% (Fn) and 1.75% ± 0.52% (Fp) (p = 0.15). Whereas thymic corpuscles occupied an area of 0.68% ± 0.19% in negative animals (Fn) only. The connective tissue covered area varied between 12.05% ± 0.68% (Fn) and 10.34% ± 0.62% (Fp) (p = 0.009). Collagen type I (p = 0.30) and type III (p = 0.59) were present in, respectively, 1.73% ± 0.3% and 0.44% ± 0.09% in Fn, and 1.44% ± 0.36 and 0.44% ± 0.13% in Fp. The FeLV virus was not able to completely modify the thymus structure of infected animals, considering the areas occupied by thymocytes, adipose tissue, blood vessels and also type I and III collagens. However, the connective tissue underwent a certain degree of remodeling since less connective tissue area was observed in FeLV infected animals. The absence of thymic corpuscles in immunosuppressed animals suggests a possible connection to thymopoiesis.

The Quarter-Horses regularly participate in non-traditional sports that simulate activities on cattle ranches. In the vaquejada races, the horses run at about 30 km/h, reaching maximum heart rates of around 200 bpm, indicating the great physical effort during competitions and with that could impact welfare. To test the hypothesis that vaquejada horses can be evaluated for the quality of welfare through a combination of non-invasive and invasive methods, an experiment was developed that aimed to assess the quality of welfare through thermography and blood biomarkers before and after vaquejada races. Ten vaquejada horses, which were in regular competition, were submitted to the vaquejadas racing test were used. Thermography was performed in 14 regions of interest (head, neck and thorax) in the following phases: pre-race and +1, +4 and +24 hours of the races. Blood samples were collected in pre-race, immediately after and +1, +4 and +24 hours of the races. Results were submitted to ANOVA and Tukey’s test, with p set at 5%. Thermography showed that local temperatures before the race and +24 hours after the races were similar (p > 0.05), as well as between +1 and +4 hours after the races (p > 0.05), which showed higher surface temperatures than the first group (pre-race and +24 hours) (p 0.05) after the exercises. In conclusion, the vaquejada horses evaluated by infrared thermography and blood analyses maintained the quality of well-being, with the physiological elevation of several parameters after the races and recovery in less than 24 hours after the races. Thermographic images were also able to help in the analysis of the regions of interest that have contact with harnesses, demonstrating that the use of adequate and correct equipment does not compromise animal welfare.

Clostridium difficile is a nosocomial enteric pathogen, considered the main etiological agent of antibiotic-associated diarrhea in hospitals. C. difficile is resistant to several antimicrobial agents used in empiric treatment protocols, which confers selective advantages to this species as compared with other members of the intestinal microbiota. The aim of this study was to evaluate and identify possible alterations of the intestinal microbiota population resulting from the use of antimicrobials associated with infections by C. difficile (CDI). Denaturing Gradient Gel Electrophoresis (DGGE) was used to evaluate fecal samples from two groups: healthy subjects and patients with C. difficile-associated diarrhea (CDAD). A decrease in bacterial diversity was highlighted by the low number of bands in samples from CDAD patients, compared with healthy subjects. This may indicate that antibiotic treatment would affect bacterial diversity, leading to a significant difference between the intestinal microbiota of these two groups, but further studies are still needed. Firmicutes and Verrucomicrobia phyla were detected mainly in healthy individuals, and these could be related to protection factors against the CDI. Klebsiella variicola/K. pneumoniae were found mostly in samples from CDI patients. This study shows the effects of antimicrobials and the CDI itself on human intestinal microbiota.

Infrared thermography (IRT) has emerged for evaluation of animal welfare. To test the hypothesis that cattle subjected to vaquejada increased temperature in the eye (CLO) and tail due to physical effort, a research was developed that aimed to measure maximum surface temperature in the CLO and base of tail using IRT. Eighty Nellore cattle were used, which were subjected to physical effort in three periods (morning, afternoon and night). IRT was performed at CLO and base of tail, in rest pen/corral (control) and during the vaquejada (pre- and post-run). Tails’ analysis was divided in 3 points (E1, E2 and E3). ANOVA and Tukey’s test (p < 0.001) were used for analysis. Temperatures were higher in morning and afternoon and different from those at night on control (p < 0.001). During vaquejada with one run, CLO was higher in pre-run, followed by a slight reduction in post-run (p < 0.001). Analyzing temperatures variations at tail, higher temperatures were observed in the morning, followed by the evening and night (p < 0.001), but without differences within the pre- and post-run periods. Temperatures at tail’s points were higher in morning period in cattle with two runs (p < 0.001). Finally, it was concluded that there were no increases in CLO or at tail’s points after vaquejada races. The IRT method was efficient in determining surface temperatures in CLO and tail points in cattle under the same conditions and may be a good noninvasive method for clinical and welfare assessments.

In recent decades, the intensity of training and equestrian competitions has significantly increased, thus the assessment of the well-being of the equine athlete has become essential in all equestrian modalities. The aim of this study was to ascertain whether equine athletes submitted to a vaquejada simulation test (VqST), comprised of three races, presented changes in blood biomarkers related to stress and health status. Fourteen healthy Quarter Horses, used as pull horses in this equestrian modality, were evaluated. Ten animals were submitted to the VqST and the remaining four were used as a control group. Blood samples were collected pre-test (during fast), immediately after, and at 1, 4 and 24 hours of recovery. The assessed blood biomarkers included cortisol, interleukin (IL)-6, IL-1β, iron, urea, creatinine, and gamma-glutamyl transferase (GGT) concentrations and results were analyzed using One Way ANOVA (time) with the SigmaStat 13.0 software. No differences between sample times were detected in both groups (p > 0.05) and no differences were found between groups (p > 0.05). The results suggest that all horses were well conditioned for the level of effort imposed by the three vaquejada races. The adaptation to physical exercise may enable the regulation of the acute response to stress in the tissues involved in the exercises, with no differences being observed in stress and health biomarkers, such as IL-6, IL-1β and cortisol. In conclusion, well-conditioned vaquejada horses exhibit a balanced regulation of biological processes, which contributes an increased athletic longevity and better quality of athletic life.

The use of medicinal plants as therapeutic and economic resources has been on the rise in recent years. In Brazil, however, increasing doubt is being cast on the quality of these products, owing to the prevalence of adulteration and fraud. Solar radiation can cause serious damage to human skin, as a result, mostly, of ultraviolet light, which is a cause of skin cancer. Photoprotective substances are capable of absorbing, reflecting, or refracting ultraviolet radiation and thus protecting skin from exposure to sunlight. The present study aimed to characterize samples and examine the phytochemical profile and photoprotective potential of bark and leaves of Erythrina velutina Willd. The samples underwent five extraction methods using 80% ethanol. The phenolic content was measured using spectrophotometry. Antioxidant activity was examined using the DPPH and the photoprotective properties of the plant extracts were assessed using the method developed by Mansur. There was a quantitative difference in some groups of metabolites, with higher levels of tannin in the bark and of flavonoids in the leaves. The latter showed greater DPPH free radical scavenging capacity than the bark, although higher levels of SPF were obtained from the bark, with no statistically significant differences between methods. The results indicate that Erythrina velutina Willd. has potential as a photoprotector.
