More patients had grade 3/4 treatment-related AEs during the induction versus maintenance phase (ACP, 40.5% v 8.2%; ABCP, 48.6% v 21.2%; BCP, 44.7% v 11.1%). During induction, the incidence of serious AEs (SAEs) was 28.3%, 28.5%, and 26.4% in the ACP, ABCP, and BCP arms, respectively. During maintenance, SAE incidences were 20.0%, 26.3%, and 13.0%, respectively. Selleck AL3818 Completion rates of the PRO questionnaires were > 88% at baseline and remained ≥ 70% throughout most study visits. Across arms, patients on average reported no clinically meaningful worsening of global health status or physical functioning scores through cycle 13. Patients across arms rated common symptoms with chemotherapy and immunotherapy similarly. Conclusion ABCP seems tolerable and manageable versus ACP and BCP in first-line nonsquamous NSCLC. Treatment tolerability differed between induction and maintenance phases across treatment arms. PROs reflect a minimal treatment burden (eg, health-related quality of life, symptoms) with each regimen.Many patients with sickle cell disease (SCD) need surgical management during their lifetime. The best approach for preoperative transfusion in SCD is still to be determined. In this single-center retrospective study, we included HBSS/HBS-Beta0-thalassemia patients younger than 16 years of age who underwent surgery between January 2008 and July 2019. Preoperative transfusion assignment (PTA) was based on SCD severity and surgical risk. Patients were assigned to no transfusion, simple transfusion, or exchange transfusion. A total of 284 patients were identified and 66 (23%) underwent 78 procedures. Mean age at the time of procedure was 8 (5-11) years, mean baseline hemoglobin was 8.5 (7.8-9.3) g/dl, and mean hemoglobin F was 18.4 ± 8.2%. SCD severity was low-risk in 57 (73%) and high-risk in 21 (27%) patients. Surgical risk was low-risk in 20 (25.6%) and medium-risk in 58 (74.4%) procedures. PTA was no transfusion in 17 (22%), simple transfusion in 40 (51%), and exchange transfusion in 21 (27%) procedures. Postoperative complications occurred in five (6.4%) of procedures only in the simple transfusion group (three acute chest syndrome, one hemolytic anemia, one pain crisis) undergoing medium-risk surgery. Preoperative risk-based transfusion assignment is feasible. Despite a high baseline hemoglobin level in the no transfusion group, none of the patients developed postoperative complications. It is possible that the high baseline hemoglobin F phenotype was protective and indicates the need to study the risk/benefit of interventions used in this phenotype.Objective To characterize clinical, radiographic, and histologic features of canine furcation cysts (CFCs) in dogs and to propose possible mechanisms of CFC development. Animals 20 client-owned dogs with CFCs biopsied between January 1, 2013, and December 31, 2017. Procedures Medical records of the Center for Comparative Oral and Maxillofacial Pathology at the University of Wisconsin-Madison were retrospectively searched to identify records of dogs that had surgical biopsy specimens of mandibular or maxillary cavitary lesions diagnosed as odontogenic cysts and that met additional inclusion criteria. Biopsy sample submission records, medical records, clinical and radiographic images, and histologic samples were reviewed. Clinical, radiographic, and histologic features were evaluated. Results Mean body weight and age of affected dogs were 23.5 kg (51.7 lb) and 8.2 years, respectively. All 20 dogs had a unilateral cyst, with the right (n = 13) or left (7) maxillary fourth premolar tooth affected and viable in all dogs. A predominant clinical sign was a fluctuant swelling of the buccal gingiva and mucosa overlying the CFC, and enucleation of the cyst lining, with or without extraction of the affected tooth, resolved the lesion in most dogs. Conclusions and clinical relevance Our findings indicated that CFC is an odontogenic cyst of uncertain etiopathogenesis and that complete evaluation of the clinical, radiographic, and histologic features of the lesion in affected patients is necessary to distinguish a CFC from other odontogenic cysts and tumors in dogs. Defining CFCs in terms of characteristic features permits accurate diagnosis and appropriate treatment of these previously unclassifiable odontogenic cysts in dogs.Objective To describe the radiographic appearance of benign bone infarcts and bone infarcts associated with neoplasia in dogs and determine the utility of radiography in differentiating benign and malignancy-associated bone infarcts. Sample 49 dogs with benign (n = 33) or malignancy-associated (16) infarcts involving the appendicular skeleton. Procedures A retrospective cohort study was performed by searching a referral osteopathology database for cases involving dogs with a histologic diagnosis of bone infarction. Case radiographs were anonymized and reviewed by 2 board-certified veterinary radiologists blinded to the histologic classification. Radiographic features commonly used to differentiate aggressive from nonaggressive osseous lesions were recorded, and reviewers classified each case as likely benign infarct, likely malignancy-associated infarct, or undistinguishable. Results Only 16 (48%) of the benign infarcts and 6 (38%) of the malignancy-associated infarcts were correctly classified by both reviewers. Medullary lysis pattern and periosteal proliferation pattern were significantly associated with histologic classification. Although all 16 (100%) malignancy-associated lesions had aggressive medullary lysis, 23 of the 33 (70%) benign lesions also did. Eight of the 16 (50%) malignancy-associated infarcts had aggressive periosteal proliferation, compared with 7 of the 33 (21%) benign infarcts. Conclusions and clinical relevance Results suggested that radiography was not particularly helpful in distinguishing benign from malignancy-associated bone infarcts in dogs.Case description A 6-year-old cat underwent tail amputation at the sacrococcygeal joint and was evaluated 5 days later because of necrosis of the skin at the surgery site and tenesmus. Tail amputation had been necessary as a result of vehicular trauma. Clinical findings Neurologic examination of the cat revealed no abnormalities. Clinical evaluation and radiography confirmed dorsal displacement of the rectum as a result of removal of the tail and transected sacrocaudal and rectococcygeal musculature as well as muscles of the pelvic diaphragm. The rectum was dilated and filled with hard feces. Treatment and outcome To correct the dorsal displacement of the rectum, bilateral semitendinosus muscle transposition was performed to restore tissue to the void created by removal of the tail, sacrocaudal muscles, muscles of the pelvic diaphragm, and rectococcygeus muscle. The cat recovered uneventfully from surgery. No further displacement of the rectum occurred and no lameness attributable to bilateral transection of the semitendinosus muscles was noted during a 2-year follow-up period.
