Background: Cognitive abilities in Alzheimer’s Disease are usually examined by formal tests conducted in a laboratory or facility. Such tests are useful for determining the severity of the disease but do not indicate the types of cognition exhibited in the daily lives of patients. This study shows significant preservation of cognition and quality of life in the daily routine of a woman with severe Alzheimer’s who was given multiple therapeutic interventions. Alzheimer’s disease involves multiple d [...]

Total pancreatectomy (TP) is increasingly being utilized for definitive treatment in patients with debilitating chronic pancreatitis (CP). In an effort to prevent surgical diabetes, the procedure can be performed in conjunction with transplantation of islets of Langerhans recovered from the patients’ own resected pancreas (autologous islet transplantation, AIT). Given that patients undergoing TP and AIT are traditionally assumed not to be at risk for the development of beta-cell autoimmunity, it is possible that th [...]

We report a case of thrombotic microangiopathy (TMA) diagnosed in the kidney allograft of a 59-year-old woman who had developed plasmacytoma type monomorphic posttransplant lymphoproliferative disorder (PTLD) 30 years after a simultaneous pancreas and kidney transplant. This report demonstrates a rare etiology of TMA in a kidney allograft occurring in association with PTLD-associated monoclonal gammopathy. The main teaching points are: 1) PTLD may be considered in the work-up of a new TMA in the immunosuppressed po [...]

Neuroleptic Malignant Syndrome (NMS) and Malignant Catatonia (MC) are conditions with significant overlap and are classically characterized by autonomic dysfunction, rigidity, bradyreflexia, posturing, lead-pipe rigidity in the former and waxy flexibility in the latter, stereotyping, an increase in creatinine kinase, and/or leukocytosis. Onset after inciting factor ranges from days to weeks, as does resolution with appropriate treatment. The overlap in symptomatology with Autism spectrum disorder (ASD) presents a f [...]

Prefabricated zirconia crowns (ZRCs) require a passive fit and more reduction than stainless steel crowns (SSC). To determine the mean and maximum reduction depths in the mesial-buccal and occlusal areas for three ZRC brands and one SSC in posterior primary typodont molars and to compare reduction depths to existing literature to determine the preparation’s proximity to pulpal tissue. Four primary maxillary and mandibular typodont teeth (J and S) were prepared according to the manufacturers’ guidelines for three ZR [...]

Background: Narratives encompass written reflection experiences and hold the potential to display valuable insights into trainees’ thinking. We analyzed narratives from graduate students trained in aging themes, who then interviewed older hospitalized adults (senior partners) about their life experiences. Methods: Three Discovery & Learning Fellows trained on open-ended interviewing, empathy, and aging themes performed semi-structured interviews. Senior partners were hospitalized older veterans. After the [...]

Background: Over the past decade, there has been rising interest in the interaction of Pneumocystis with the environment. This interest has arisen in part from the demonstration that environmental factors have important effects on the viability and transmission of microbes, including Pneumocystis. Environmental factors include climatological factors such as temperature, humidity, and precipitation, and air pollution factors including carbon monoxide, nitrogen dioxide, sulfur dioxide, and particulate matter. Methods [...]

Polycystic ovary syndrome (PCOS) is the most common endocrinopathy causing non-ovulation infertility in women. Women with PCOS have higher levels of luteinizing hormone (LH), testosterone, cholesterol and triglycerides but, in contrast, lower levels of follicular stimulating hormone (FSH) and sex hormone-binding globulin (SHBG) compared with healthy counterparts. Because of the limitations of human studies, animal models of PCOS have been developed to identify appropriate therapeutics and to explore their mechanism [...]

Strongyloides stercoralis infection derived from the donor in solid organ transplant (SOT) places recipients at risk for hyperinfection syndrome and death. We describe the case of a lung transplant recipient who developed strongyloidiasis presenting with GI symptoms and progressing to diffuse alveolar hemorrhage, bacteremia and multi-organ failure. The patient's clinical course illustrates the life cycle of Strongyloides. For treatment, the patient received ivermectin and albendazole. We advocate that early diagnos [...]

This paper presents a three-phase full-bridge boost switch-mode rectifier (SMR) fed switched-reluctance motor (SRM) drive with energy storage buffer. First, the power circuits and control schemes of the two power stages are properly designed. Except for having good line drawn power quality, the boostable DC-link voltage of the SRM drive can enhance the SRM driving performance in wide speed range. And the recovered regenerative braking energy can be sent back to the grid successfully. Then, a battery storage system [...]
