Microfilaremia by Cercopithifilaria bainae in a dog from the central western region of Brazil: case report / Microfilaremia por Cercopithifilaria bainae em um cão da região Centro-Oeste do Brasil: relato de caso

Cercopithifilaria bainae is a nematode belonging to the family Onchocercidae that parasitizes the subcutaneous tissue of dogs. Its transmission occurs through the tick Rhipicephalus sanguineus and its geographical distribution overlaps that of this vector. The present study reports the detection of microfilaremia by C. bainae in an eight-year-old male dog that presented anorexia, hyperthermia, motor incoordination, mydriasis, a nodule in the left testicle and concomitant infection by Ehrlichia sp. Blood samples were analyzed using microscopy, PCR and DNA sequencing. Microfilariae measuring 150±5.5µm in length and 7±1.8µm in width were retrieved. The DNA sequence exhibited 98% identity with C. bainae sequences available in Genbank. This is the first report of microfilaremia by C. bainae in a dog in the central western region of Brazil.(AU)

Blood pressure control in a registry of clinical practice, PINNACLEBRAZIL REGISTRY

INTRODUCTION: The prevalence of hypertension is estimated to be nearly 50% among Brazilian adults. Achieving an adequate control of this CVD risk factor is challenging but truly relevant on a public health perspective, as this is the top ranking cause of all deaths globally. PURPOSE: We aimed to describe crude and simple metrics of blood pressure management (including its control), as based on current guidelinederived recommendations, after one year of the clinical practice registry METHODS: Patients with documented Hypertension were included by using electronic case report form based on the ACC PINNACLE Registry. The registry has been enrolling patients from general practitioners and specialists. The main goal of the PINNACLE program is to improve the quality of care in "real world" clinical practice. Patients data were evaluated after 01 year of follow-up on regular clinical appointments and the differences on clinical practice were evaluated RESULTS: Currently, PINNACLEBrazil has enrolled 7598 patients, with 87% of diagnosed hypertension. Percentage of patients with a diagnosis of hypertension who had a blood pressure measurement <140/90 mmHg was 47.9%(baseline) and 57.3% (followup). Percentage of patients who had a blood pressure < 140/90 mm Hg, or who had a blood pressure >= 140/90 mm Hg and were prescribed >= 2 antihypertensive medications were 67.1% on baseline and 71.2% after 1 year. CONCLUSION: The preliminary data of PINNACLE Registry in Brazil shows that a significant proportion of hypertensive patients (nearly half) have not presented with adequate control of blood pressure levels and, moreover, a large proportion have not been treated with recommended combination of 02 or more antihypertensive medications to reach targeted BP levels the quality of care was improving after 01 year of registry.

Array-CGH analysis in patients with intellectual disability and/or congenital malformations in Brazil.

In several patients, intellectual disability and/or congenital malformation may be attributed to chromosomal changes. In this study, we conducted an array-CGH test of 200 patients from the Northeast of Brazil with intellectual disability and/or congenital malformation. Blood samples were collected from the proband and from their parents when possible. DNA was extracted and investigated using the array-CGH test. Findings were evaluated for the pathogenicity in databases of benign and pathogenic changes (ISCA, UCSC, DGV, and DECIPHER). Forty-seven copy number variations (CNVs) were identified in 43/200 (21.5%) patients, including 25/98 (25.5%) in males and 22/102 (21.57%) in females. We considered 33 of these to be clinically significant, reaching a diagnosis rate of 16.5%. The sizes of the CNVs varied from 102 kb to 24 Mb in deletions and from 115 kb to 140 Mb in duplications. In 10/47 (21.3%) patients, the rearrangement involved a sex chromosome. Thirty-nine patients had one chromosomal aberration, while 2 concomitant abnormalities were detected in 4 patients. Ten of 47 CNVs (21.3%) were > 5Mb in size. Fifteen patients had CNVs related to known syndromes. This research highlights the contribution of submicroscopic chromosomal changes to the etiology of intellectual disability and/or congenital malformation, particularly the implication of chromosomal abnormalities detected using an array-CGH test, with a high rate of 16.5%. Thus, our results support the use of array-CGH replacing standard karyotype as the first-tier cytogenetic diagnostic test for patients with multiple congenital anomalies and/or intellectual disability.

Avaliações clínica, ecográfica e anatomofisiológica do alotransplante parcial de vesícula urinária com células-tronco mesenquimais alogênicas derivadas do tecido adiposo em coelhos / Clinical, sonographic, anatomic and physiological assessments of partial allotransplant urinary bladder with allogeneic mesenchymal stem cells derived from adipose tissue in rabbits

Os problemas relacionados ao armazenamento vesical são muitos e relevantes. Eles, além de influírem de forma efetiva na qualidade de vida, podem eventualmente evoluir para falência renal. Existem vários trabalhos, os quais descrevem as propriedades imunomoduladoras e imunossupressoras das células-tronco mesenquimais derivadas do tecido adiposo (ADSCs). Objetiva-se com o presente avaliar clínica, ecográfica e anatomofisiologicamente o alotransplante parcial de bexiga a fresco em coelhos, utilizando como agente imunomodulador ADSCs alogênicas. Para isso foram utilizados 25 coelhos, sendo um deles macho e doador das ADSCs, e os outros 24 eram fêmeas, submetidas a alotransplante parcial de bexiga, sendo tratadas com ciclosporina (GCi) ou células-tronco mesenquimais (GCe). Conclui-se que as ADSCs foram suficientes para evitar sinais clínicos e ecográficos de rejeição ao alotransplante de vesícula urinária, mantendo a estrutura anatomofisiológica vesical por até 30 dias em coelhos.

The problems related to bladder storage are many and significant. In addition to effectively impacting the quality of life, they can eventually progress to kidney failure. There are several studies which describe the immunomodulatory and immunosuppressive properties of ADSCs. The aim of this study is to clinically, through sonography, anatomically and physiologically evaluate fresh partial allograft bladder from rabbits using allogeneic ADSCs as immunomodulator agents. For such, 25 rabbits were used, one being a male ADSCs donor, and the other 24 females who underwent simultaneous partial allograft bladder, being treated with cyclosporine (GCi) or mesenchymal stem cells (GCe). It was concluded that ADSCs were sufficient to prevent clinical and ultrasound signs of allograft rejection of the urinary bladder. These bladders retained the anatomophysiological structure for 30 days in rabbits.

Association between advanced oxidation protein products and 5-year mortality risk among amazon riparian elderly population.

Proteins are important targets of several modifications caused by oxidative stress, leading to structural changes and consequently partial or total loss of their functions. The oxidized proteins include advanced oxidation protein products (AOPP) derived from oxidation-modified albumin, as well as fibrinogen and lipoproteins. An increase in AOPP levels indicates an oxidative stress state and the presence of coexisting inflammation. Several investigations have also suggested an association between high AOPP levels and aging-related diseases. However, the link between elevated AOPP levels and elderly mortality risk has not yet been investigated. Here, we report on a 5-year longitudinal study that investigated the potential association between AOPP levels and mortality using a population-based representative sample of riparian elders living in Brazilian Amazon region (Maués-AM). Age, sex, socioeconomic and cultural conditions, chronic morbidities, polypharmacy, and previous morbidities were also tested as potential confounders. The AOPP levels were measured in 540 (84.78%) individuals, all of whom were followed over a 5-year period in order to establish the mortality rate. Within this study period, 74 (13.7%) elders died and 466 (86.3%) survived. The AOPP levels were higher among the elders who died within the 5-year period (46.27 ± 40.6 mmol/L) compared with those who survived (36.79 ± 20.84 mmol/L) (p = 0.002). The analysis confirmed the link between high AOPP levels and mortality risk, independent of other intervenient factors. These results suggest that elevated AOPP levels could be used to predict mortality risk in elderly patients.

Inhibitory effects of the essential oil of Mentha pulegium on the isolated rat myometrium.

The effects of the essential oil of Mentha pulegium L. (EOMP), a plant commonly known as "pennyroyal" or "poejo" that is used in folk medicine as an abortifaceant, were assessed on the isolated rat myometrium. Myometrial strips were stimulated with 10 nM oxytocin or 10 microM PGF (2alpha). EOMP (10 - 300 microg/mL) concentration-dependently and reversibly inhibited the amplitude of oscillatory contractions, being approximately 3-fold more active against contractions stimulated by oxytocin than those by PGF (2alpha) (IC (50) values of 45.7 +/- 5.6 microg/mL and 160.9 +/- 5.9 microg/mL , respectively), although the maximal inhibitory effect occurred at the same concentration (300 microg/mL ) in both cases. This action was shared by pulegone (30 - 300 microM), the principal component of the essential oil (IC (50) values of 21.8 +/- 2.1 microg/mL and 12.7 +/- 4.6 microg/mL , respectively). Nifedipine (30 nM - 30 microM) also abolished agonist-stimulated contractions, and was approximately twice and 12 times as potent as EOMP in inhibiting oxytocin- and prostaglandin F (2alpha) (PGF (2alpha))-stimulated contractions, respectively. In conclusion, our results show that the essential oil of the abortifaceant plant Mentha pulegium exerts an inhibitory effect on the contractile activity of the isolated rat myometrium. This oil shares a common effect with the voltage-dependent calcium channel (VDCC) blocker nifedipine, although ostensibly acting via a different mechanism. It thus appears that EOMP and pulegone do not exert direct toxic effects on the myometrium per se that would cause abortion, and other possibilities such as systemic metabolism of plant constituents may rather underlie the abusive use of Mentha pulegium in popular medicine.
