Digenetic trematodes infection in a Bothrops moojeni (Viperidae) population from a fauna rescue in Porto Primavera, São Paulo State

No presente estudo é descrita a infecção por trematódeos digenéticos parasitas da cavidade oral e esôfago em uma população de serpentes Bothrops moojeni provenientes de resgate de fauna em Porto Primavera, Estado de São Paulo. Foi observada prevalência de infecção de 68%. O grau de infecção (número de trematódeos por serpente) variou de 2 a 51 helmintos. Os trematódeos encontrados foram Ophisthogonimus spp. e Sticholecitha serpentis. A alta prevalência de infecção foi associada com a drástica alteração ambiental e o estresse multi-fatorial aos quais os animais foram submetidos, que poderiam ter favorecido o ciclo dos parasitas.

Trajetória de profissionais da saúde de um hospital colônia para hanseníase

Leprosy as a public health problem , there is still quite some time , even with treatment for decades . Your health-disease process is marked by a historical backdrop of stigma , prejudice, social exclusion and authoritarian decisionducts , in order to extinguish the disease milieu under the regime of compulsory confinement of the patient. In this perspective , the Brazilian public health twentieth century adopted policies of compulsory isolation , which meant that those who receive a diagnosis of leprosy were isolated from society and their families in hospitals colonies . Objective is, to the study, rescue the trajectory of health professionals in the Colony Hospital St. Francis of Assisi , in Natal / RN ; Identify the policy was perceived as compulsory institutionalization imposed for leprosy patients by health professionals ; describe the behaviors Professional Hospital adopted in Cologne ; Retrieve information about the existence and functioning of the Hospital and Create a documentary of historical fragments of leprosy from the point of view of professionals from a former colony. Exploratory - descriptive method with a qualitative approach , using the methodological framework thematic oral history was used . Obtained approval by the IRB of the Federal University of Rio Grande do Norte, under Protocol No 461 403 and CAAE 19476913.9.0000.5537 . Be interviewed during the period of November and December 2013 , five health professionals who worked in the hospital colony , using audio recorder and images to capture and record the statements. The interviews were transcribed , textualized, transcriadas and sent to reviewers to step conference of the reports. Subsequently , analysis of the stories was made from the proposed content analysis of Bardin . The results and discussion are presented in the form of article: Opinion of nursing professionals who worked in a hospital for leprosy colony , which aimed to : identify the opinion of nurses who worked in hospital colony on the lives of patients . In this article, three main themes were highlighted and discussed from the reports of colaboradoes : I - The socialization process of internal II - 16 Prejudice , stigma and discrimination III - Social exclusion versus inclusion . We conclude that , in the context of the colony hospital, the performance of health professionals contributed significantly to that stigma , prejudice and social exclusion would be minimized and that the experience of asylum seekers in the colony were not seen more traumatic

The Impact of Tacrolimus as Rescue Therapy in Children Using a Double Immunosuppressive Regimen After Heart Transplantation

Background. Organ transplant recipients with refractory rejection or intolerance to the prescribed immunosuppressant may respond to rescue therapy with tacrolimus. We sought to evaluate the clinical outcomes of children undergoing heart transplantation who required conversion from a cyclosporine-based, steroid-free therapy to a tacrolimus-based regimen. Methods. We performed a prospective, observational, cohort study of 28 children who underwent conversion from cyclosporine-based, steroid-free therapy to a tacrolimus-based therapy for refractory or late rejection or intolerance to cyclosporine. Results. There was complete resolution of refractory rejection episodes and adverse side effects in all patients. The incidence rate (X100) of rejection episodes before and after conversion was 7.98 and 2.11, respectively (P <= .0001). There was a 25% mortality rate in patients using tacrolimus after a mean period of 60 months after conversion. Conclusion. Tacrolimus is effective as rescue therapy for refractory rejection and is a therapeutic option for pediatric patients.

Protein quality control disruption by PKC beta II in heart failure: rescue by the selective PKC beta II inhibitor, beta IIV5-3

Myocardial remodeling and heart failure (HF) are common sequelae of many forms of cardiovascular disease and a leading cause of mortality worldwide. Accumulation of damaged cardiac proteins in heart failure has been described. However, how protein quality control (PQC) is regulated and its contribution to HF development are not known. Here, we describe a novel role for activated protein kinase C isoform beta II (PKC beta II) in disrupting PQC. We show that active PKC beta II directly phosphorylated the proteasome and inhibited proteasomal activity in vitro and in cultured neonatal cardiomyocytes. Importantly, inhibition of PKC beta II, using a selective PKC beta II peptide inhibitor (beta IIV5-3), improved proteasomal activity and conferred protection in cultured neonatal cardiomyocytes. We also show that sustained inhibition of PKC beta II increased proteasomal activity, decreased accumulation of damaged and misfolded proteins and increased animal survival in two rat models of HF. Interestingly, beta IIV5-3-mediated protection was blunted by sustained proteasomal inhibition in HF. Finally, increased cardiac PKC beta II activity and accumulation of misfolded proteins associated with decreased proteasomal function were found also in remodeled and failing human hearts, indicating a potential clinical relevance of our findings. Together, our data highlights PKC beta II as a novel inhibitor of proteasomal function. PQC disruption by increased PKC beta II activity in vivo appears to contribute to the pathophysiology of heart failure, suggesting that PKC beta II inhibition may benefit patients with heart failure.

Rescue technique for salvaging toric intraocular lens alignment

Accurate alignment of a toric intraocular lens (IOL) is a requisite to achieving the intended reduction in astigmatism at the time of cataract surgery. However, it requires a reasonably clear view of the limbal vascular anatomy, which is sometimes altered by chemosis from a subconjunctival anesthetic injection or a hemorrhage. We describe a technique that can quickly restore vascular anatomy and facilitate toric IOL alignment.

Capsulorhexis rescue after peripheral radial tear-out: Quick-pull technique

We describe a technique to rescue the continuous curvilinear capsulorhexis (CCC) in cases in which complete radial tears make it impossible to use normal traction forceps. A circumferential path and rapid movement are applied in the plane of the anterior capsule in the direction of the center pupil. This technique was used in 50 cases. In 47, the CCC could be completed; in 3, it could not and surgery was continued with low-parameter phacoemulsification. No other intraoperative complications occurred.

Pharmacological Rescue of Dendritic Pathology in the Ts65Dn Mouse Model of Down Syndrome

Down syndrome (DS) is a genetic pathology characterized by brain hypotrophy and severe cognitive disability. Although defective neurogenesis is an important determinant of cognitive impairment, a severe dendritic pathology appears to be an equally important factor. It is well established that serotonin plays a pivotal role both on neurogenesis and dendritic maturation. Since the serotonergic system is profoundly altered in the DS brain, we wondered whether defects in the hippocampal development can be rescued by treatment with fluoxetine, a selective serotonin reuptake inhibitor and a widely used antidepressant drug. A previous study of our group showed that fluoxetine fully restores neurogenesis in the Ts65Dn mouse model of DS and that this effect is accompanied by a recovery of memory functions. The goal of the current study was to establish whether fluoxetine also restores dendritic development and maturation. In mice aged 45 days, treated with fluoxetine in the postnatal period P3-P15, we examined the dendritic arbor of newborn and mature granule cells of the dentate gyrus (DG). The granule cells of trisomic mice had a severely hypotrophic dendritic arbor, fewer spines and a reduced innervation than euploid mice. Treatment with fluoxetine fully restored all these defects. Moreover the impairment of excitatory and inhibitory inputs to CA3 pyramidal neurons was fully normalized in treated trisomic mice, indicating that fluoxetine can rescue functional connectivity between the DG and CA3. The widespread beneficial effects of fluoxetine on the hippocampal formation suggest that early treatment with fluoxetine can be a suitable therapy, possibly usable in humans, to restore the physiology of the hippocampal networks and, hence, memory functions. These findings may open the way for future clinical trials in children and adolescents with DS.

Trattamento della malattia paranale complessa di Crohn: rescue therapy dopo fallimento dei farmaci biologici

La malattia paranale di Crohn rappresenta una condizione clinica complessa e invalidante. La chirurgia da sola è efficace nel migliorare i sintomi mediante il controllo della sepsi, ma è raramente associata alla guarigione definitiva. L'introduzione dei farmaci biologici ha aumentato le possibilità di chiusura definitiva delle fistole. Tuttavia molti pazienti non rispondono a questo trattamento bio-chirurgico combinato. Il ruolo del mucosal healing del retto ottenuto con i farmaci non è al momento ancora chiaro. L'obiettivo del presente studio è quello di identificare possibili terapia alternative per pazienti non responsivi ai biologici. Lo studio ha valutato efficacia e sicurezza della chirurgia riparativa, confezionamento di flap mucosi endorettali e posizionamento di protesi biologiche, nei pazienti non responsivi ai biologici ma che grazie ad essi abbiano ottenuto un mucosal healing del retto.

OPA1 isoforms and protein domains in the rescue of mitochondrial dysfunctions

Mutations in OPA1 gene have been identified in the majority of patients with Dominant Optic Atrophy (DOA), a blinding disease, and the syndromic form DOA-plus. OPA1 protein is a mitochondrial GTPase involved in various mitochondrial functions, present in humans in eight isoforms, resulting from alternative splicing and proteolytic processing. In this study we have investigated the specific role of each isoform through expression in OPA-/- MEFs, by evaluating their ability to improve the defective mitochondrial phenotypes. All isoforms were able to rescue the energetic efficiency, mitochondrial DNA (mtDNA) content and cristae integrity, but only the presence of both long and short forms could recover the mitochondrial morphology. In order to identify the OPA1 protein domains crucial for its functions, we selected and modified the isoform 1, shown to be one of the most efficient in preserving mitochondrial phenotype, to express three specific OPA1 variants, namely: one with a different N-terminus portion, one unable to generate short form owing to deletion of S1 cleavage site and one with a defective GTPase domain. We demonstrated that the simultaneous presence of the N- and C-terminus of OPA1 was essential for the mtDNA maintenance; a cleavable isoform generating s-forms was necessary to completely rescue the energetic competence and the presence of the C-terminus was sufficient to partially recover the cristae ultrastructure. Lastly, several pathogenic OPA1 mutations were inserted in MEF clones and the biochemical features investigated, to correlate the defective phenotypes with the clinical severity of patients. Our results clearly indicate that this cell model reflects very well the clinical characteristics of the patients, and therefore can be proposed as an useful tool to shed light on the pathomechanism underlying DOA.
