The Port Delivery System with ranibizumab (PDS) is an investigational drug delivery system designed to provide continuous intravitreal release of ranibizumab for extended durations. The PDS consists of a permanent, surgically placed, refillable intraocular implant; a customized formulation of ranibizumab; and ancillary devices to support surgery and refill procedures. selleck kinase inhibitor A toxicology program was conducted to evaluate the ocular toxicology and biocompatibility of the PDS to support its clinical development program and product registrational activities. PDS safety studies included a 6-month chronic toxicology evaluation in minipigs as well as evaluation of nonfunctional surrogate implants (comprised of the same implant materials but without ranibizumab) in rabbits. Biocompatibility of the implant and ancillary devices was evaluated in both in vitro and in vivo studies. Implants and extracts from implants and ancillary devices were nongenotoxic, noncytotoxic, nonsensitizing, and nonirritating. Ocular findings were comparable between implanted and sham-operated eyes, and no systemic toxicity was observed. The results of this nonclinical toxicology program demonstrated that the PDS was biocompatible and that intravitreal delivery of ranibizumab via the PDS did not introduce any new toxicology-related safety concerns relative to intravitreal injections, supporting ongoing PDS clinical development and product registrational evaluation.Objective Narrative Exposure Therapy (NET) is a short-term trauma-focused intervention originally developed for treating survivors of war and torture. The neurobiological theoretical foundations of NET would suggest that the approach should have long term beneficial effects. We tested this assumption and also provided an extensive overview of all NET studies for adults, for children (KIDNET), and for perpetrators (Forensic Offender Rehabilitation NET; FORNET). Method Following a systematic literature review, we conducted meta-analyses with all studies that had control conditions, and with all Randomized Controlled Trials (RCTs). We assessed between-groups short- ( less then 6 months) and long-term (≥ 6 months) effect sizes for symptoms of posttraumatic stress disorder (PTSD) and depression. Results In a total of 56 studies from 30 countries comparing 1370 participants treated with NET to 1055 controls, we found large between group effect sizes regarding the reduction of PTSD symptoms in favor of NET. Analyses of RCTs with active controls yielded small to medium effect sizes in the short-term, and large effect sizes in the long-term. Conclusions NET, KIDNET, and FORNET yield beneficial and sustainable treatment results for severely traumatized individuals living in adverse circumstances. Studies in highly developed health care systems comparing NET with other evidence-based trauma-focused interventions are needed.Lipid-rich carcinoma is a rare histotype of canine mammary tumors with cytoplasmic vacuolation. In humans, glycogen-rich carcinoma, secretory carcinoma, and myoepithelial neoplasms are included in the differential diagnosis for lipid-rich carcinoma. The aim of the study was to investigate the existence of histotypes other than lipid-rich in canine mammary carcinomas with vacuolated cytoplasm using a diagnostic algorithm based on histopathology, histochemistry, immunohistochemistry, and ultrastructure and to evaluate the molecular phenotype of these neoplasms. Ten mammary carcinomas were collected, histologically reviewed, and subjected to histochemistry (PAS, PAS with diastase, Alcian blue, Sudan III [1 case], and Congo red [1 case]); immunohistochemistry for CK19, CK5/6, CK14, p63, calponin, vimentin, ER, PR, and HER2; and transmission electron microscopy (TEM). Cytokeratin immunolabeling demonstrated the epithelial origin of all tumors. Sudan III and TEM confirmed the diagnosis of lipid-rich carcinoma in 8 tumors (one amyloid-producing). One tumor was reclassified as a glycogen-rich carcinoma based on PAS reactivity that was diastase-labile, and a second tumor was reclassified as a carcinoma-and-malignant myoepithelioma based on the differentiation markers. Lipid-rich carcinomas were basal-like (5/8), null-type (2/8), and luminal A phenotype (1/8). The glycogen-rich carcinoma was basal-like, while the carcinoma-and-malignant myoepithelioma was luminal A. Vacuolated morphology of neoplastic cells in canine mammary carcinoma can indicate either a neoplasm of luminal epithelial origin with cytoplasmic lipid or glycogen, or vacuolated neoplastic suprabasal myoepithelial cells. Glycogen-rich carcinoma is a novel histological type that should be considered in the differential diagnosis for canine mammary carcinomas with vacuolated cytoplasm.Degenerative changes in the aorta are commonly observed in both dogs and humans, and those changes that occur with age morphologically overlap with those observed in genetic or degenerative diseases. Therefore, recognition of age-related aortic changes is important for diagnosticians, as such histologic findings should be distinguished from lesions of specific diseases. The aortas from 37 dogs without clinical cardiovascular disease ranging in age from 2 months to 15 years were divided into 3 cohorts to assess age-relatedness, and evaluated histologically using standardized nomenclature and diagnostic criteria adapted and modified from the human literature. We found that the histopathologic severity scores for intimal thickening, translamellar medial fibrosis, loss of smooth muscle cell nuclei, and medial microcalcification were higher in older dogs, whereas the scores for both intralamellar and translamellar mucoid extracellular matrix accumulation ("cystic medial necrosis") were not different among age groups. Dogs with translamellar medial fibrosis and aortic medial microcalcification were significantly older compared with dogs without these findings, while the presence of aortic medial chondro-osseous metaplasia was not related to age. Taken together, we demonstrate a range of age-related aortic histologic changes in dogs without clinical cardiovascular disease and suggest that integration of signalment and clinical data can aid in the differentiation of such findings from non-age-related disease processes.
