- Abstract
Ovarian tissue transplantation makes it possible to restore fertility; however, the success of this technique depends on the transplant region used. Therefore, this study aimed to evaluate the effect of two subcutaneous regions on canine ovarian transplantation, pinna (Pi) and neck (Ne), for 7 and 15 days. Ovaries collected by ovariosalpingohysterectomy were fragmented using a punch device. Fresh fragments were fixed, and the others were immediately grafted onto the animal itself in the Pi and Ne regions for 7 and 15 days. Recovered fragments were evaluated for histology (morphology, development and stromal density), picrosirius (collagen fibers), and immunohistochemistry (fibrosis and cell proliferation). The results showed that follicular normality rates were lower in Pi-7 (78%) vs. control (90%) and Pi-15 (86%), similar in Ne-7 (92%) and superior in Ne-15 (97%) compared to the control, with the effect of the region Ne (94%) superior (P < 0.05) to Pi (82%). Stromal density reduced in both regions vs. control but was similar within 15 days. Fragments from both regions showed higher fibronectin labeling and deposition of type I and lower type III collagen fibers (P < 0.05) vs. control. Proliferation rates in Ne-7 were higher (P < 0.05) than in control, and Pi-15 was higher (P < 0.05) than Ne-15. In conclusion, the pinna may be a region with greater potential than the neck after a 15-day autotransplantation of canine ovarian tissue., (© 2023.

- Abstract
Background: Arterial hypertension treatment guided by central blood pressures (CPB) rather than peripheral blood pressures (PBP) measurement has the potential to show greater effectiveness in preventing or even regressing stiffness and target organ damage (TOD)., Objective: This study aimed to compare the parameters of CBP and PBP measurements, arterial stiffness, TOD and renal profile in patients with anti-hypertensive treatment guided by CBP or PBP targets., Methods: A randomized clinical trial was conducted in central group (CG) and peripheral group (PG). Patients were randomized, evaluated every 3 months for BP and antihypertensive adjustments during a one-year follow up. The procedures in V1 and V5: anthropometric assessment; CBP/PBP measurements, carotid ultrasound; echocardiography; laboratory tests. Paired and unpaired t -tests and the χ
2 were used (significance level: 5%)., Results: The study evaluated 59 participants (30CG/29PG). The augmentation index (AIx) was higher in the CG (27.3% vs. 20.3%, p = 0.041). Intergroup analysis has found central diastolic BP lower in the CG (78.9 vs. 84.3 mmHg, p = 0.024) and the Alx difference between groups ceased to exist after a one-year follow-up. Intragroup comparisons, after intervention, showed a lower frequency of changed PWV ( p < 0.001) and LVMI ( p = 0.018) in the CG. The PG showed a higher frequency of changed PWV ( p < 0.001) and LVMI ( p = 0.003)., Conclusion: The intervention guided by central BP reduced the central diastolic BP and AIx compared to the PG. There was a reduction in the frequency of changed PWV and LVMI in the CG., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Guimarães Filho, de Oliveira Vitorino, Inuzuka, Barroso, Pacífico Alves Filho, Melo, de Oliveira Urzeda, Lima Sousa, Coca, Veiga Jardim and Barroso.)- Published

- Abstract
Objectives: The purpose of this study was to evaluate the correlation between clinical aspects and urethral lesions with reproductive status and age at neutering in obstructed male cats., Methods: All cats with compatible signs of urethral obstruction (UO) treated at the Veterinary Hospital of the Federal Rural University of Pernambuco from 2019 to 2021 were divided into three groups according to their reproductive status: intact; prepubertal neutered; and post-pubertal neutered. Cats with compatible signs of UO were selected for further analysis. Age, clinical signs, age at neutering and age of the first obstructive event were documented. Cats with recurrent obstructive urinary signs or urethral trauma that made catheterization impossible were referred for perineal urethrostomy. The morphology of the excised penises was assessed by histopathological analysis., Results: Of 84 cats with signs of UO included in this study, 28.6% were classified as intact, 28.6% as prepubertal neutered and 42.8% as post-pubertal neutered. Intact cats had a significantly earlier onset of UO compared with prepubertal and post-pubertal neutered cats, as seen by the age at obstruction (3.6 vs 5.7 and 5.5 years, respectively). Similar clinical signs and histopathological lesions were observed in all groups. The main clinical signs observed were stranguria, hematuria and pollakiuria. All cats had some degree of injury in the penile urethra. The most common lesions were hemorrhage, fibrosis and congestion., Conclusions and Relevance: It appears that intact cats had an earlier onset of UO than neutered cats, regardless of age at neutering. Urethral histopathological lesions and clinical signs were similar in both groups. Pediatric neutering represents a useful tool in the control of abandoned and stray animals and the consequent dissemination of zoonoses, thus having a positive impact on public health.

- Abstract
Down Syndrome or trisomy 21 (T21) is a genetic condition caused by the presence of an extra chromosome in pair 21 and is related to a high prevalence of agenesis of permanent teeth and periodontal alterations that may be associated to the loss of permanent teeth at early ages. With the increase in life expectancy of people with T21 in the last decades, it is necessary to expand the knowledge to offer possibilities of treatment with dental implants, aiming to serve this aging population., Aims: The aim of this article is to report a surgical procedure of sinus lift to enable the installation of dental implants in the posterior region of the maxilla., Methods and Results: A 50 year-old patient with T21 was rehabilitated with implants, simultaneously with sinus lift surgery, by the lateral window technique, using xenogenous bone graft and fibrin-rich plasma. After 1 year, the patient was rehabilitated with prosthetics on implants., Conclusion: The feasibility of this technique in patients with Down syndrome could be observed, after 3 years of follow up, with favorable clinical results., (© 2022 Special Care Dentistry Association and Wiley Periodicals LLC.)

- Abstract
Purpose: To investigate the association of the single-nucleotide polymorphism rs35934224 in the TXNRD2 gene with primary open-angle glaucoma in a Brazilian population., Methods: This was a cross-sectional study conducted to verify the association between the rs35934224 TXNRD2 (thioredoxin reductase 2) and primary open-angle glaucoma in a population from the Northeast region of Brazil. A total of 184 individuals were enrolled, including 94 with primary open-angle glaucoma (45 men and 49 women) and 94 controls (40 men and 54 women) from the Recife Eye Institute., Results: The mean age was 68.85 years for the patients with glaucoma and 68.55 years for the controls. Genomic DNA was isolated using commercially available kits, and single-nucleotide polymorphism was detected with real-time polymerase chain reaction using TaqMan probes. The studied population was in Hardy-Weinberg equilibrium. The CT genotype was associated with protection against primary open-angle glaucoma (p=0.022)., Conclusion: Our data suggest an association between TXNRD2 gene polymorphism (rs35934224) with primary open-angle glaucoma in an admixed Brazilian po pulation. This is the first study to investigate this single-nucleo tide polymorphism in Latin American individuals with primary open-angle glaucoma.

- Abstract
Oesophageal cancer is among the ten most common types of cancer worldwide. More than 80% of the cases and deaths related to the disease occur in developing countries. Local socio-economic, epidemiologic and healthcare particularities led us to create a Brazilian guideline for the management of oesophageal and oesophagogastric junction (OGJ) carcinomas. The Brazilian Group of Gastrointestinal Tumours invited 50 physicians with different backgrounds, including radiology, pathology, endoscopy, nuclear medicine, genetics, oncological surgery, radiotherapy and clinical oncology, to collaborate. This document was prepared based on an extensive review of topics related to heredity, diagnosis, staging, pathology, endoscopy, surgery, radiation, systemic therapy (including checkpoint inhibitors) and follow-up, which was followed by presentation, discussion and voting by the panel members. It provides updated evidence-based recommendations to guide clinical management of oesophageal and OGJ carcinomas in several scenarios and clinical settings., Competing Interests: Duilio R Rocha-Filho: personal fees from Bayer, Merck Serono and Servier.

- Abstract
There is a huge gap between the number of patients worldwide requiring versus those actually receiving safe, sustainable, and equitable care for kidney failure. To address this, the International Society of Nephrology coordinated the development of a Strategic Plan for Integrated Care of Patients with Kidney Failure. Implementation of the plan will require engagement of the whole kidney community over the next 5-10 years., (Copyright © 2020 International Society of Nephrology. All rights reserved.)

- Abstract
Objectives: The aim of this study was to evaluate and compare the long-term clinical outcomes and quality of life of cats having undergone perineal urethrostomy (PU) or prepubic urethrostomy (PPU)., Methods: This clinical study followed 28 cats (PU, n = 22; PPU, n = 6) that underwent a urethrostomy, with a minimum of 1 year postoperative follow-up. Medical records, pet owner surveys and urologic laboratory tests were used for assessment. Urologic laboratory tests included serum symmetric dimethylarginine (SDMA), serum creatinine, urinalysis, urine specific gravity (USG), urine protein:creatinine (UPC) ratio and urine culture., Results: The main indications for urethrostomy were multiple catheterizations and PU stricture. The overall complication rates of PU and PPU were 31.8% and 83.3%, respectively. Recurrent urinary tract infection (UTI) and urine scald dermatitis were less frequent in PU than in PPU cats (UTI 22.7% vs 66.6%; dermatitis 4.5% vs 83.3%). Bacteriuria was present in 77.2% and 100% of PU and PPU cats, respectively. Owner satisfaction rates were excellent in 81.8% of PU and 33.3% of PPU cases., Conclusions and Relevance: A proportion of cats that underwent urethrostomy showed bacteriuria, recurrent UTIs and increased levels of SDMA. PPU is important as a salvage procedure; however, it should be limited to cases in which standard techniques for PU cannot be performed, owing to the potential for recurrent complications and lower owner satisfaction.

- Abstract
Introduction and Objectives: Viral hepatitis is an endemic and epidemic disease of relevance in public health. This study estimated the frequency of viral hepatitis by occupational and non-occupational infections and analyzed the factors associated with case notifications in Brazil from 2007 to 2014., Material and Methods: This was an exploratory epidemiological study using the Notifiable Diseases Information System database. Descriptive and multivariate analyses were performed., Results: The frequency of viral hepatitis by occupational infections was 0.7%, of which 1.3% were due to hepatitis A virus (HAV), 45.1% hepatitis B virus (HBV), and 45.3% hepatitis C virus (HCV). There was a significant association of the disease with female sex [AOR=1.31; P=0.048], schooling [AOR=1.71; P<0.001], occupation [AOR=2.74; P<0.001], previous contact with an HBV or HCV-infected patient [AOR=5.77; P<0.001], exposure to accidents with biological materials [AOR=99.82; P<0.001], and hepatitis B vaccination [AOR=0.73; P=0.033]., Conclusion: While there was a low frequency of viral hepatitis by occupational infections in Brazil from 2007 to 2014, these findings might be underreported and have been associated with individual and occupational characteristics. This reinforces the need for the adoption of prevention strategies in the workplace and for completeness of case notifications., (Copyright © 2019. Published by Elsevier España, S.L.U.)

- Abstract
Even today, an effective diagnostic test for aspergillosis in penguins is unknown, being the gold standard post-mortem examinations. The fungal antigen galactomannan (GM) has been used as a biomarker of disease in humans and is detected by the Platelia Aspergillus EIA (BioRad)®, a commercial kit based on the sandwich ELISA technique. It is standardized for use in neutropenic patients, however studies have demonstrated its usefulness also possible for birds. The aim of our study was to evaluate the effectiveness of Platelia Aspergillus EIA® test (BioRad-US) in the diagnosis of aspergillosis in Magellanic penguins, determining sensitivity, specificity, and positive and negative predictive values for different cut-off points. Were included in the study, blood serum samples (n = 29) Magellanic penguins in captivity that died by aspergillosis. Detection of GM was performed following manufacturer's instructions and the GM index was obtained by dividing the average value of OD of the duplicate of the clinical sample by duplicate OD of the average value of the cut-off sample provided by the kit. Through information database results were obtained for the presence of anti-Aspergillus fumigatus antibodies detected by agar gel immunodiffusion (AGID) for all serum samples. Results were analyzed using chi-square test and Kruskal-Wallis from SPSS 20.0, IBM®. ROC curve was obtained and from this, rates of sensitivity, specificity, positive and negative predictive values were also calculated based on four different cutoff points (0.5, 1.0, 1.5 and 2.0). The serum GM index did not differ between animals of the case and control group (pkw =0.097). In determining the ROC curve for serum GM detection the value of area under the curve was 0.635. From the values determined by the coordinate of the curve, four different cut points (0.5, 1.0, 1.5 and 2.0) were analyzed, resulting in sensitivity rates ranging from 86.2 to 34.5% % and specificity between 87% and 26.1%. By comparing the serum GM index in group case as the presence or absence of antibodies detected by AGID was found p=0.503. The detection of GM the Platelia Aspergillus EIA® test seems is not be useful for the diagnosis of aspergillosis in naturally infected penguins.

- Abstract
The Magellanic Penguin ( Spheniscus magellanicus) is native to Argentina, Chile, and the Falkland/Malvinas Islands, and is a regular winter migrant in Uruguayan and Brazilian coastal waters. The species is known to be susceptible to a variety of gastrointestinal nematodes, cestodes, trematodes, and acanthocephalans, as well as renal trematodes and pulmonary nematodes. Schistosomes (Platyhelminthes, Trematoda, Schistosomatidae) and microfilariae (Nematoda, Secernentea, Onchocercidae) were histologically identified in Magellanic Penguins ( Spheniscus magellanicus) that died while under care at rehabilitation centers in southern Brazil. Phylogenetic analysis of the COI gene, ITS-1 region, 5.8S rRNA gene, ITS-2 region, and 28S rRNA gene sequences of the schistosome revealed that it is closely related to, but distinct from, a schistosome reported from the African Penguin ( Spheniscus demersus). The schistosomes from Magellanic and African Penguins were grouped with Gigantobilharzia huronensis, Gigantobilharzia melanoidis, and Dendritobilharzia pulvurenta; however, the lack of a clearly monophyletic origin precludes determining their genus. The incidental discovery of novel parasites during a study that did not specifically aim to investigate the occurrence of helminths underscores the value of histopathological examination as an exploratory diagnostic approach.

- Abstract
Background: The Neck Circumference (NC) is an anthropometric measure to evaluate obesity. The FINDRISC predicts the risk of developing type 2 diabetes mellitus. Our aims were to identify the mean value of NC in individuals with higher (≥15 points) and lower FINDRISC and to establish cutoff values that indicate individuals with higher FINDRISC., Methods: It is a population-based, cross-sectional study representative of the city of Curitiba, Brazil. We studied individuals (>18 years), without diabetes mellitus, between August 2013 and August 2014. We evaluated anthropometric parameters, glycaemia, socioeconomic situation, chronic conditions, and their risk factors. In a sex-specific analysis, data are presented as mean and standard deviation. We performed Pearson's and Spearman's correlation between NC and the waist circumference, body mass index and FINDRISC. Receiver Operating Characteristic curves were estimated for NC and higher FINDRISC. Logistic regression models were built to analyze the association between higher FINDRISC and 1-SD increase in NC., Results: We studied 950 individuals (621 women) with a mean age of 47.4 ± 17.6 years and body mass index of 26.2 ± 5.6 kg/m2. The mean NCs were 34.1 ± 3.1 cm in women and 38.2 ± 3.5 cm in men. Mean NC was lower in women (33.7 ± 2.9 cm vs. 35.8 ± 3.2 cm) and men (37.7 ± 3.4 cm vs. 41 ± 3.6 cm) with lower FINDRISC (p <0.001). All the correlations with NC were significant (p ≤ 0.001). The area under the curve for NC and the higher FINDRISC was 0.702 (95% CI 0.653 - 0.752) for women and 0.762 for men (95% CI 0.679 - 0.845), determining the best cutoff value of 34.5 cm for women and 39.5 cm for men to discriminate individuals with higher FINDRISC. Fully adjusted odds ratios for higher FINDRISC per 1-SD increase in NC in women and men were, respectively 1.89 (95% CI 1.53 - 2.33) and 2.86 (95% CI 1.91 - 4.29)., Conclusion: NC is positively correlated to the body mass index, waist circumference, glycaemia, and FINDRISC scores in a population-based sample of adults. We identified the mean values of NC in higher and lower FINDRISC and established cutoff values for NC and higher FINDRISC., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.)

- Abstract
Background: Currently, there is an epidemic expansion of obesity rates worldwide. The increasing number of obese individuals associated with the aging of population leads to increasing number of individuals with type 2 diabetes mellitus (T2DM) at the same rate. The traditional factors that link obesity to T2DM are related to genetics, hypercaloric diet, sedentary lifestyle, and stress. Individuals from lower Socioeconomic Status (SES) have restricted autonomy and opportunities that could lead to more stress and consequently increase in stress hormones, such as cortisol, catecholamines, glucagon, and growth hormone, which might ultimately change fat deposition, increasing visceral fat and increasing the risk of T2DM development., Methods: We conducted a review of the literature on the effects of low SES and the risk of developing T2DM in obese persons., Results: 191 studies were found. The obesity of lower SES individuals is more central than that for individuals from higher socioeconomic position. It is also proposed that the quality of food seems to be lower, with more intake of fat and simple carbohydrates and less of fruits, vegetables and whole wheat bread, in the more disadvantaged social classes. The lower income neighborhoods, without exercise facilities and unsafety are also associated with higher indices of physical inactivity. Cross sectional and prospective studies confirm the relationship between lower socioeconomic status and obesity and diabetes. The lower SES is associated to metabolic implications that are linked to insulin resistance and possibly may also interfere with the ability of beta cell to secrete insulin and change the gut microbiota, increasing even more the future risk of developing diabetes., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.)

- Abstract
Pollution from anthropogenic marine debris (AMD) is currently the most widely distributed and lasting anthropic impact in the marine environment, affecting hundreds of species, including all sea turtles. In this study, the patterns of AMD distribution along the gastrointestinal tract (GT) and their relationship with obstructions and faecalomas in 62 green turtles (Chelonia mydas) that died during rehabilitation in southern Brazil were determined. The GT was split in seven sections, corresponding to the natural organs and intestinal areas morphologically and physiologically distinct. Mean mass (4.24g) and area (146.74cm
2 ) of AMD in the stomach were higher than in other sections. The anterior portion of the rectum had the highest number of obstructions, followed by the stomach. AMD was associated with the obstructions, with positive correlation between faecalomas and AMD masses. Organs and subdivisions showed marked differences in susceptibility to obstructions caused by AMD, which deserves attention in clinical interventions., (Copyright © 2017 Elsevier Ltd.

- Abstract
Different herpesviruses have been associated with respiratory and enteric disease and mortality among seabirds and waterfowl. In 2011, a respiratory disease outbreak affected 58.3% (98/168) of the Magellanic penguins undergoing rehabilitation due to an oil spill off the southern Brazilian coast. Etiology was attributed to a novel herpesvirus identified by histopathology, immunohistochemistry, electron microscopy and molecular studies with partial DNA sequencing. Since migration, rehabilitation and translocation may facilitate the spread of pathogens between populations and trigger the onset of clinical disease in animals with latent infections, investigation of herpesvirus occurrence in asymptomatic seabirds was performed. Samples from free-ranging seabirds were collected in Argentinian Patagonia (Magellanic penguins) and the Abrolhos Archipelago in Brazil (Brown boobies, Masked boobies, Red-billed tropicbirds, White-tailed tropicbirds and South American tern). Furthermore, asymptomatic seabirds housed at the facility where the outbreak occurred were also sampled. In total, 354 samples from eight seabird species were analyzed by PCR for herpesvirus. Four different sequences of herpesviruses were identified, one in Yellow-nosed Albatross, one in Boobies and Tropicbirds and two in Magellanic penguins. Magellanic penguin herpesvirus 1 was identified during the penguin outbreak at the rehabilitation facility in Brazil, while Magellanic penguin herpesvirus 2 was recovered from free-ranging penguins at four reproduction sites in Argentina. Phylogenic analysis of the herpesviruses sequences tentatively identified suggested that the one found in Suliformes and the one associated with the outbreak are related to sequences of viruses that have previously caused seabird die-offs. These findings reinforce the necessity for seabird disease surveillance programs overall, and particularly highlight the importance of quarantine, good hygiene, stress management and pre-release health exams in seabirds undergoing rehabilitation.

- Abstract
Objectives The aim of this study was to compare the sensitivity of acetate tape impression with skin squeezing and superficial skin scraping methods for the diagnosis of burrowing mites ( Notoedres cati) in cats. Methods Samples were collected from 50 cats showing signs of notoedric mange. The most affected region was selected for sampling using acetate tape impression with skin squeezing, and superficial skin scraping. Results No significant difference was observed in the number of mites found by both methods, regardless of the stage of development of the mite. The tests showed a high correlation to the total number of mites (r = 0.928). However, in two animals it was possible to confirm the presence of N cati only by the acetate tape impression test. Conclusions and relevance We conclude that the acetate tape impression test is a good method for confirming the presence of N cati in cats. In our experience, this technique is as sensitive as superficial skin scraping, even in animals presenting with a low infestation. Moreover, the technique is less traumatic and allows the collection of clinical specimens in more sensitive locations, such as the eyelids, lips and paws.

- Abstract
Aspergillosis, an opportunistic mycosis caused by the Aspergillus genus, affects mainly the respiratory system and is considered one of the most significant causes of mortality in captive penguins. This study aimed to examine a 6-yr period of cases of aspergillosis in penguins at the Centro de Recuperação de Animais Marinhos (CRAM-FURG), Rio Grande, Brazil. A retrospective cohort study was conducted using the institution's records of penguins received from January 2004 to December 2009. Animals were categorized according to the outcome "aspergillosis," and analyzed by age group, sex, oil fouling, origin, prophylactic administration of itraconazole, period in captivity, body mass, hematocrit, and total plasma proteins. A total of 327 Magellanic penguins (Spheniscus magellanicus) was studied, 66 of which died of aspergillosis. Proportionate mortality by aspergillosis was 48.5%, and incidence density was 7.3 lethal aspergillosis cases per 100 penguins/mo. Approximately 75% of the aspergillosis cases occurred in penguins that had been transferred from other rehabilitation centers, and this was considered a significant risk factor for the disease. Significant differences were also observed between the groups in regard to the period of time spent in captivity until death, hematocrit and total plasma proteins upon admission to the center, and body mass gain during the period in captivity. The findings demonstrate the negative impacts of aspergillosis on the rehabilitation of Magellanic penguins, with a high incidence density and substantial mortality.

- Abstract
Aim: To assess the effects of each traditional cardiovascular risk factor (hypertension, diabetes mellitus, dyslipidemia, and smoking), including the presence of coronary artery disease (CAD), on carotid intima-media thickness (CIMT) and to assess the degree of carotid plaque occurrence., Methods: A total of 553 outpatients (216 men and 337 women; mean age 67.06 ± 12.44 years) who underwent a carotid artery ultrasound were screened for carotid plaque and CIMT measurements., Results: The CIMT medians were higher in males ( P < .001) and in patients with hypertension ( P < .001). A linear increase occurred in mean CIMT of 0.0059 mm for each year of increase in age. The presence of plaque indicated a tendency to correlate with CIMT ( P = .067). The presence of hypertension associated with diabetes ( P = .0061; estimated difference 0.0494 mm) or dyslipidemia ( P = .0016; estimated difference 0.0472 mm) or CAD ( P = .0043; estimated difference 0.0527 mm) increased the mean CIMT measurements. The probability of plaque occurrence in carotid arteries is influenced by the age ( P < .001) and is higher in patients with dyslipidemia ( P = .008) and CAD ( P < .001)., Conclusions: Hypertension is the strongest cardiovascular risk factor that increases CIMT, followed by age and male sex. Age and dyslipidemia increase the probability of carotid plaque. Increased CIMT and plaque could be present in the same patient caused by different risk factors and with independent effects on the artery wall and different clinical prognoses.

- Abstract
Objective: The present study aimed to evaluate whether patient education level interferes in the percentage of pain relief or increase using visual analogue scale (VAS) and subjective pain perception., Patients and Methods: Ninety-five patients presenting acute shoulder pain due to enthesitis were evaluated. They were asked to quantify the pain using VAS before steroid articular infiltration. One week later, patients reevaluated the pain using VAS and orally stated the percentage of perceived pain increase or relief. The information gathered was then compared among three patient educational levels (elementary, high school, and university)., Results: Percentages of improvement stated orally and utilizing VAS presented no statistically significant differences among the three educational status levels (p = 0.804)., Conclusion: Patient educational status caused no impact in the results of acute pain self-assessment with VAS and oral evaluation.

- Abstract
Seabird rehabilitation is a valuable strategy to mitigate the impacts of oil pollution and other anthropogenic factors, and can significantly contribute to the conservation of penguins. However, infectious diseases such as avian malaria (Plasmodium spp.) can hamper the success of rehabilitation efforts. We combined morphological and molecular diagnostic methods to investigate the epidemiology and pathology of Plasmodium in Magellanic penguins (Spheniscus magellanicus) at rehabilitation centers along 2500 km of the coastline of Brazil. True prevalence of malarial parasites was estimated between 6.6% and 13.5%. We identified five species, three of which had not been described infecting penguins (P. cathemerium, P. nucleophilum, P. unalis); an additional five distinct Plasmodium lineages were also distinguished, and albeit unidentified these clearly correspond to species that also have not yet been reported in penguins. Our results indicate that the diversity of plasmodia that may infect these birds is greater than previously recognised. Considering the well-defined seasonality observed in this study, it is clear that rehabilitation centers could benefit by narrowing their preventative efforts on penguins maintained or admitted during the Austral spring-summer, particularly by preventing mosquitoes from coming into contact with penguins.

- Abstract
Background: C.E.R.A. is a continuous erythropoietin receptor activator with characteristics that permit a once-monthly schedule of administration for the maintenance treatment for chronic kidney disease (CKD) patients. The main objective of this study was to assess the maintenance of Hb concentration with once-monthly intravenous and/or subcutaneous C.E.R.A. therapy in Latin American dialysis patients with chronic renal anemia previously treated with epoetin alfa s.c or i.v 1-3 times per week., Methods: This was a single-arm, open-label, multicenter, 32-week study of anemic patients with CKD previously treated with epoetin alfa sc or iv 1-3 times per week. After a 4-week screening period, during which mean Hb levels were maintained between 10.5 and 12.5 g/dL on their previous erythropoiesis stimulating agent, eligible patients entered a 16-week C.E.R.A. dose titration period followed by a 4-week efficacy evaluation period (EEP) and a 28-week safety follow-up. The starting dose of C.E.R.A. was based on the previous dose of epoetin alfa. Doses of C.E.R.A. were then adjusted to maintain Hb levels within ±1.0 g/dL of the reference concentration and between 10.5 and 12.5 g/dL. The Hb reference concentration was defined as the mean of all Hb levels during screening. The primary end point was the proportion of patients maintaining a mean Hb concentration (g/dL) within ±1 g/dL of their reference Hb and between 10.5 and 12.5 g/dL during the EEP., Results: A total of 163 patients from 27 centers in Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Peru, Uruguay, and Venezuela entered the treatment period and 102 completed the prescribed course of C.E.R.A. Forty-five patients (43.7 %) maintained a mean Hb concentration within ±1 g/dL of their reference Hb value and between 10.5 and 12.5 g/dL during the EEP. The median monthly dose remained constant at 120 μg during the titration period and during the EEP. On the average, there were only 2.3 dose changes per patient in 28 weeks of treatment, covering 7 C.E.R.A. scheduled administrations. 53 % of all dose changes were dose decreases, 47 % increases. A total of 10 AEs and 4 SAEs were considered to be related to the study treatment., Conclusions: Once-monthly C.E.R.A. treatment effectively maintains stable Hb concentrations in patients with chronic renal anemia undergoing dialysis with a good safety and tolerability profile.

- Abstract
Purpose: To examine the prevalence of ocular surface complaints in Brazilian patients with glaucoma or ocular hypertension who used topical intraocular pressure (IOP)-lowering regimens., Methods: In this multicenter, noninterventional, single-visit study, adults with glaucoma or ocular hypertension treated with an IOP-lowering regimen were administered the 12-item ocular surface disease index (OSDI) questionnaire. Each response was scored on a 5-point scale, with 0 indicating symptom present none of the time and 4 indicating symptom present all of the time. The average of the 12 item responses for each patient was transformed to a scale from 0 to 100, with higher scores representing worse disabilities. OSDI results then were categorized as absence of OSD (scores of 0-12), mild OSD (scores of 13-22), moderate OSD (scores of 23-32), or severe OSD (scores of 33100)., Results: The 173 enrolled patients had a mean age of 61.2 years, were women in 65.3% of cases, and had glaucoma in 89.0% of cases and ocular hypertension in 11.0% of cases. OSDI scores for 158 patients using 1 IOP-lowering therapy indicated no OSD in 37.3% of patients (59/158), mild OSD in 20.9% (33/158), moderate OSD in 17.1% (27/158), and severe OSD in 24.7% (39/158). For the 120 patients using 1 IOP-lowering medication and having a known duration of diagnosis of glaucoma or ocular hypertension, mean OSDI scores were numerically higher (worse) for the 39 patients with a diagnosis ≥6 years long (score 25 [± 20], indicating moderate OSD) than for the 81 patients with a diagnosis lasting <6 years (score 22 [± 20], indicating mild OSD); however, no significant differences in OSDI scores by duration of diagnosis were evident in means (P=0.49), distributions (P≥0.26), or correlation (P=0.77)., Conclusions: A large proportion of Brazilian patients treated with 1 IOP-lowering therapy had some ocular surface complaints.

- Abstract
The effects of polysaccharides, including xyloglucan from Hymenaea courbaril (XG), galactomannans from Schizolobium parahybae (GMSP) and Mimosa scabrella (GMMS), xanthan gum (XT), sodium hyaluronate (HNa) and Fucogel(®) (FG), on the rheological behavior of cosmetic emulsions were evaluated. These incorporations gave rise to six emulsified systems, denoted XGE, GMSPE, GMMSE, XTE, HNaE and FGE, respectively. The emulsion consistency was found to follow the trend GMSPE>XGE>HNaE>FGE>XTE>GMMSE. In general, the addition of polysaccharides increased the viscoelastic properties of the emulsions and decreased the creep compliance. The neutral polysaccharides (GMSPE, GMMSE) led to better stability of the emulsions after storing for 20 days relative to charged polymers. It was found that polysaccharides XG, GMSP and GMMS, which come from the seeds of native Brazilian plant species, might be used to modify the flow properties and stabilities of oil-water emulsions., (Copyright © 2012 Elsevier Ltd.

- Abstract
The parenchymal distribution of the splenic artery was studied in order to obtain anatomical basis for partial splenectomy. Thirty two spleens were studied, 26 spleens of healthy horses weighing 320 to 450 kg, aged 3 to 12 years and 6 spleens of fetus removed from slaughterhouse. The spleens were submitted to arteriography and scintigraphy in order to have their vascular pattern examined and compared to the external aspect of the organ aiming establish anatomo-surgical segments. All radiographs were photographed with a digital camera and the digital images were submitted to a measuring system for comparative analysis of areas of dorsal and ventral anatomo-surgical segments. Anatomical investigations into the angioarchitecture of the equine spleen showed a paucivascular area, which coincides with a thinner external area, allowing the organ to be divided in two anatomo-surgical segments of approximately 50% of the organ each.

- Abstract
Oil pollution is a significant conservation concern. We examined data from six institutions along the coast of South America: Emergency Relief Team of the International Fund for Animal Welfare, Fundación Mundo Marino, Centro de Recuperação de Animais Marinhos, Natura Patagonia, Associação R3 Animal, and Mar del Plata Aquarium and data from resightings in Argentina, Brazil, Chile and Falkland/Malvinas Islands. From 2000 to 2010, 2183 oiled Magellanic penguins were rehabilitated as part of the routine activities of these institutions or during emergency responses to eight oil spills in which they were involved; all rehabilitated penguins were flipper banded and released. Since their release, 41 penguins were resighted until 31 December 2011. The results demonstrate that, when combined with other prevention strategies, the rehabilitation of Magellanic penguins is a strategy that contributes to the mitigation of adverse effects of oil spills and chronic pollution to the species., (Copyright © 2012 Elsevier Ltd.

- Abstract
Objective: To evaluate PAI-1 genotypes in a group of infertile women with or without endometriosis and control subjects., Design: Case-control study., Setting: Human Reproduction Center of Medicina do ABC Faculty., Population: One hundred and forty infertile women with endometriosis, 64 women with idiopathic infertility and 148 fertile women as control subjects., Methods: The PAI-1 4G/5G polymorphism was identified by restriction fragment length polymorphism-polymerase chain reaction., Main Outcome Measures: Genotype distribution and allele frequency of the 4G/5G polymorphism of the PAI-1 gene., Results: The frequencies of genotypes 4G/4G, 4G/5G and 5G/5G of the PAI-1 gene in the infertile women with endometriosis were 38.6, 37.1 and 24.3%, respectively, and in the control group 24.3, 33.8 and 41.9%, respectively (p=0.003). When the infertile women with endometriosis were divided according to their endometriosis stage, genotypes 4G/4G, 4G/5G and 5G/5G were identified, respectively, in 36.7, 32.9 and 30.4% of the patients with minimal/mild endometriosis (p=0.102) and in 41.0, 42.6 and 16.4% of the patients with moderate/severe endometriosis (p=0.001); in the women with idiopathic infertility, these genotypes were found at a frequency of 29.7, 34.3 and 36%, respectively (p=0.637)., Conclusion: The data suggest that, in Brazilian women, the PAI-1 4G/5G polymorphism may be associated with a risk of endometriosis-associated infertility., (© 2011 The Authors Acta Obstetricia et Gynecologica Scandinavica© 2011 Nordic Federation of Societies of Obstetrics and Gynecology.)

- Abstract
Purpose: to evaluate the frequency of TP53 codon 72 polymorphism in infertile women with endometriosis, women with idiopathic infertility, controls and its relation to the disease., Methods: a case-control study that included 198 infertile women with endometriosis, 70 women with idiopathic infertility and 169 fertile women without endometriosis as control. Detection of TP53 codon 72 gene polymorphism (rs1042522, Arg/C:Pro/G), that promotes a C/G exchange in the coding region of the gene, was performed by real time Polymerase Chain Reaction (PCR), using the TaqMan system of primers, that flank the implicated region and probes labeled with different fluorescent dyes, one for allele C and other for allele G. When two dyes were observed, the patient was considered to be heterozygous CG. In the presence of only one dye, the individual was considered to be homozygous CC or GG. The χ2 test was used to compare allele and genotype frequencies between groups. All p-values were two-tailed and a p-value <0.05 was considered to be statistically significant., Results: we found no statistically significant difference in the distribution of TP53 codon 72 polymorphism genotypes CC, CG or GG (p=0.7) and alleles C or G (p=0.4) between infertile patients with endometriosis and controls (p=0.4), regardless of the stage of the disease. In relation to infertility, no statistically significant difference in the genotype or allele distribution (p=1.0 and p=0.9, respectively) was observed between idiopathic infertile women and controls. Considering the dominant inheritance model, again, no statistically significant difference was found even in the endometriosis (p=0.5) or the idiopathic infertility group (p=0.9) when compared to controls. Regarding the recessive inheritance model no statistically significant difference was found, with p=0.6 and p=1.0, respectively, for the endometriosis and idiopathic infertility groups., Conclusion: the results suggest that the TP53 codon 72 polymorphism does not confer genetic susceptibility to endometriosis and/or infertility in the Brazilian population, not even the severe form of the disease.

- Abstract
The ability to think strategically is an admired and a sought-after leadership requirement, yet we know little about how it develops. The purpose of this study is to identify specific experiences that contribute to the development of an individual's ability to think strategically. We identified eight work experiences, including different types of organizational projects, processes, and relationships, that contribute to an individual's strategic thinking ability. We also delineate specific characteristics material to each experience. These characteristics indicate that considerable time and focus are required to develop the ability to think strategically. In addition, the experiences are not all accessed equally: Women are less likely to have nonrelational experiences, while chief executive officers are more likely to have the most challenging ones. In addition, we found differences regarding work-related continuing education activities. Respondents rated nonhealthcare conferences and reading behind all other identified experiences that contribute to strategic thinking ability. Individuals can implement several strategies to improve their strategic thinking ability, including deliberately incorporating the requisite experiences into their development plans, ensuring that the experiences incorporate the required characteristics, and improving the benefit received from attending educational programs in nonhealthcare industries. Organizations can implement several strategies to ensure the experiences are as effective as possible, such as appraising gender differences across the experiences and reviewing the organization's strategic planning processes for the characteristics that best encourage strategic thinking.

- Abstract
Oxamniquine is an antiparasitic agent commonly used in therapeutics against Schistosoma mansoni. Although it is well tolerated, some adverse effects justify the search for new compounds with prolonged biological action, so that monomeric and polymeric oxamniquine prodrugs were designed. Synthetic results assisted by molecular modeling study showed the possibility to obtain the corresponding monomeric forms of the oxamniquine methacrylate (1) and oxamniquine acrylamide (2). Successful copolymerization procedure only occurred on the methacrylic compound, generating the oxamniquine methacrylate copolymer (3). Submitted to a preliminary in vivo biological evaluation, a similar oxamniquine profile was observed to the monomeric forms although an inadequate drug release may be responsible for the methacrylic copolymer failure.

- Abstract
Background/aims: Scanning laser polarimetry (SLP) uses a confocal scanning laser ophthalmoscope with an integrated polarimeter to evaluate the thickness of the retinal nerve fibre layer (RNFL). The aim of this study was to verify the ability of the SLP to detect differences in RNFL thickness between normal and glaucomatous eyes and between glaucomatous eyes subdivided in groups by the severity of visual field damage., Methods: This was a cross sectional retrospective study. The charts of 40 healthy subjects and 68 glaucoma patients who underwent complete ophthalmological examination, optic disc stereophotography, peripapillary, and macular SLP imaging were reviewed. The right eye of subjects eligible for the study was enrolled. Only eyes with SLP examinations indicating a minimised effect of anterior segment birefringence based on macular image were included. The ability of retardation parameters to discriminate between healthy and glaucomatous eyes was evaluated. Based on visual field loss, glaucoma patients were subdivided in three subgroups (early, moderate, and severe). RNFL thickness between healthy control group and glaucoma subgroups was compared. RNFL thickness and visual field loss correlation was evaluated., Results: There was a significant difference in superior and inferior maximum RNFL thickness between normal and glaucomatous eyes (p<0.001). With these two parameters, the area under receiver operator characteristic curve was 0.75 and 0.74, respectively. Superior and inferior RNFL thickness was significantly different between healthy control group and all glaucoma subgroups (p<0.001) and between glaucoma subgroups (p<0.05), except for early and moderate glaucoma subgroups (p>0.05). Linear regression showed a weak correlation between RNFL thickness and visual field loss., Conclusion: These results suggest that once visual field loss is established, smaller reductions in the RNFL thickness detected by SLP are necessary for a given reduction of mean defect value.

- Abstract
Purpose: To study the unaffected fellow eye in patients with glaucoma and unilateral visual field defect, using conventional automated achromatic perimetry, blue-yellow short-wavelength automated perimetry (SWAP), and a nerve fiber layer analyzer (GDx; Laser Diagnostic Technologies, San Diego, CA)., Methods: Eighteen patients in whom a unilateral visual field defect was detected on conventional computerized threshold perimetry were selected. The contralateral eyes of these patients were studied with normal conventional threshold perimetry using blue-yellow perimetry and also were studied with the nerve fiber layer analyzer. Also, 18 eyes of 18 sex- and age- (+/-3 years) matched persons without glaucoma were selected as a control group., Results: Of the 18 contralateral eyes, seven (38.8%) showed a visual field defect on blue-yellow conventional perimetry, and 10 (55.5%) showed a defect of the nerve fiber layer when evaluated with the nerve fiber analyzer. Of the 10 eyes with abnormal visual fields on the nerve fiber analyzer, six (60.0%) also showed a defect on blue-yellow perimetry. In the control group, no eyes showed visual field defect on SWAP, but three eyes (16.6% false positive rate) showed a visual field defect on the nerve fiber layer analyzer., Conclusion: These findings suggest that what appeared to be unilateral visual field defects may in fact have been bilateral in at least 33.3% of our patients (n = 6) for whom there was agreement between results of SWAP and the nerve fiber layer analyzer.
