the framework presented here for advancing MRI capacity in SSA. While these findings pertain to SSA, the framework provides a model for advancing imaging needs in other low-resource settings.

Dyslipidemia is a risk factor for post- transplant diabetes mellitus, especially in patients who are taking tacrolimus. Although lipotoxicity of dyslipidemia leads to β-cell failure, the handling of lipids by β cells is a mystery in molecular endocrinology. Likewise, lipid droplet homeostasis is appreciated as a key component of lipid metabolism in cells like hepatocytes, but its role in β cells remains to be elucidated.

To evaluate the morphologic changes in β cells with special focus on lipid droplets, we evaluated electron micrographs under metabolic stress conditions of glucotoxicity, lipotoxicity, and glucolipotoxicity in isolated rat insulinoma INS-1E β cells. Cells were treated with palmitic acid (0.5 mM), glucose (33 mM), or both for 16 hours, after which morphologic changes were observed with an electron microscope.

Many lipid droplets were observed in the cytoplasm of healthy β cells in the control group (no treatment). Lipid droplets were also visible in the cytosol, and the cytoplasm was ric seemed important in the homeostasis of β-cell metabolism. In this preliminary study, healthy β cells appeared rich in lipid droplets under normal conditions. However, lipotoxicity depleted and glucolipotoxicity decreased the number of lipid droplets in β cells. Because dyslipidemia causing lipotoxicity is one of the most frequent metabolic problems in transplant patients and increases risk of posttransplant diabetes mellitus, understanding the mystery of lipid droplets in β cells and the pathophysiology of diabetes in transplant patients is important, especially for those taking tacrolimus.Fulminant hepatitis remains a critical health problem owing to its high mortality rate and the lack of effective therapies. An increasing number of studies have shown that glutamine supplementation provides protective benefits in inflammation-related disorders, but the pharmacological significance of glutamine in lipopolysaccharide (LPS)/D-galactosamine (D-Gal)-induced fulminant hepatitis remains unclear. In the present study, the potential effects of glutamine on LPS/D-Gal-induced fulminant hepatitis were investigated. Pretreatment with glutamine decreased plasma activities of alanine and aspartate aminotransferases, and ameliorated hepatic morphological abnormalities in LPS/D-Gal-exposed mice. Glutamine pretreatment also inhibited LPS/D-Gal-induced tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) production. this website In addition, glutamine pretreatment decreased the level of cleaved cysteinyl aspartate-specific proteinase 3 (caspase-3), suppressed the activities of caspase-3, caspase-8, and caspase-9, and reduced the number of cells positive for TdT-mediated dUTP nick-end labeling in LPS/D-Gal-challenged mice. Interestingly, post-treatment with glutamine also provided protective benefits against LPS/D-Gal-induced acute liver injury, although these effects were less robust than those of glutamine pre-treatment. Thus, glutamine may have potential value as a pharmacological intervention in fulminant hepatitis.Silicosis, a progressive, fibrotic occupational lung disease with no known treatment, is an uncommon indication for lung transplant. There is a paucity of research on patients with silicosis who have received lung transplants. The long-term consequences of the native lung in patients with severe chronic silicosis who have had a single-lung transplant are also of interest. We present a case of amyloidosis in a patient who underwent a single-lung transplant for silicosis.Chronic inflammatory demyelinating polyneuropathy (CIDP) is a chronic immune-mediated peripheral form of polyneuropathy. No reliable diagnostic biomarkers are available by which to make the diagnosis of CIDP. As a result, diagnosis of the condition can be challenging. Many patients are not recognized early in the disease course, and on the other end of the spectrum both establishing early and accurate diagnosis as well as avoiding misdiagnosis and overtreatment. Identification of the hallmark clinical, electrophysiological, and laboratory features of the disease are critical to facilitate rapid diagnosis, while an understanding of diagnostic pitfalls can help prevent misdiagnosis. Since the original description of CIDP in the 1970s, over 15 sets of diagnostic criteria have been proposed. The criteria published in 2021 by the European Academy of Neurology / Peripheral Nerve Society (EAN/PNS) were developed for use during routine clinical care and are available in the public domain. These criteria provide clinicians with an invaluable resource by which the data collected during the evaluation of the patient with possible CIDP can be interpreted. One point of importance that bridges diagnosis to treatment is objectification of the treatment response. Interpretation of how patients respond to treatment drives both long-term treatment paradigms and the diagnosis at which these treatments are aimed. Although no approach is perfect, utilization of strength impairment and disability outcomes in clinical practice can help unravel the difficulties in interpreting response to treatment. Just as improvement in these outcomes is considered diagnostically supportive, the absence of objective benefit argues against it and should prompt reconsideration of a CIDP diagnosis.Acute graft-versus-host disease is an extremely rare complication after pediatric liver transplant. Despite a better prognosis in pediatric than in adult recipients, graft-versus-host disease is associated with high mortality. We report 2 cases of pediatric recipients with acute graft-versus-host disease; both had identical clinical presentation. Remission was achieved in both patients, but the first patient developed Epstein-Barr virus-induced posttransplant lymphoproliferative disease and recurrence of graft-versus-host disease after the immunosuppression regimen was altered. The treatment options and clinical considerations for care of such patients are discussed. It is important to maintain a high degree of suspicion for graft-versus-host disease in every posttransplant patient with persistent skin rash, with or without fever and diarrhea, and confirm the diagnosis.A wide range has been reported for the ultrasonographic measurements of the normal adrenal gland in rabbits. Therefore, having sufficient information about the normal measurements of the adrenal gland and their relationship with indicators such as weight, sex and the diameter of the internal abdominal aorta will be of great help in diagnosing diseases of the adrenal gland. In the present study, 21 healthy adult intact rabbits were selected. The abdominal cavity of the animals was examined using ultrasound; adrenal gland parameters such as length, width, height, circumference and area on the right and left sides were measured in both sagittal and transverse planes. Additionally, the diameter of the abdominal aorta in the sagittal plane was imaged. After statistical analysis, the parameters of the adrenal glands on the right and left showed a positive significant correlation with the weight and the diameter of the abdominal aorta, although no significant correlation was found between these parameters and sex. The ratio of adrenal gland parameters to abdominal aortic diameter was calculated and the statistical analysis of the values showed that, except for the ratio of left adrenal area to aortic diameter, the other ratio of adrenal gland parameters to abdominal aortic diameter was not significantly related to weight. Therefore, these ratios can be used as suitable indicators for assessing the change in size of the adrenal gland of rabbits of different sizes. Knowing the relationship between normal adrenal measurements and the indices such as weight, sex and diameter of the abdominal aorta can help clinicians and researchers evaluate the changes in the size of the adrenal gland.A novel one-pot transition metal-free and Brönsted acid mediated 1,6-conjugate addition of bisnuleophilic diol on biselectrophilc para-quinone methide followed by ipso cyclization assisted by NBS has been developed under mild reaction conditions, offers a new approach to synthesize spiro 1,4-dioxane cyclohexadienone derivatives. This strategy features broad substrate scope of p-QMs with high functional group tolerance and good yields of spirocyclic scaffolds (60-92 %). N-Bromo succinimide an important role in an ipso spirocyclization with high efficiency.Mucormycosis can result in serious morbidity and mortality, especially in transplant recipients. In this case report, we present a 3-year-old female patient with maple syrup urine disease who developed mucormycosis infection after deceased donor split liver transplant. Progressive segmental necrosis of the small intestines and new ischemic areas were observed after repeated abdominal surgeries. Microscopic examination of biopsy material revealed mucormycosis. Early recognition is crucial for treatment, and patients with clinical suspicion can be treated empirically with antifungal medicine. However, diagnostic tests with accurate and fast results are needed and more effective therapeutic methods should be developed for better outcomes.Common variable immunodeficiency can be associated with various hepatic conditions, the most common being nodular regenerative hyperplasia. Multiple cases of liver transplant in adults with common variable immunodeficiency have been reported. Here, we report a 51-year-old man with common variable immunodeficiency and noncirrhotic portal hypertension due to nodular regenerative hyperplasia who underwent liver transplant. The patient received tacrolimus/steroid immunosuppression and remained rejection free; however, he developed cytomegalovirus infection, disseminated nocardiosis, Pseudomonas pneumonia, and Clostridioides difficile- associated colitis. All infections were successfully managed. The graft was well functioning after 18 months; however, alkaline phosphatase remained elevated and a liver biopsy showed evidence of recurrent nodular regenerative hyperplasia. The patient was started on a steroid taper, which led to normalization of the alkaline phosphatase. Two years later, a repeat biopsy confirmed recurrent nodular regenerative hyperplasia. Immunosuppression was kept low, and intravenous immunoglobulin infusions were continued. More than 10 years later, the patient is alive with a functioning graft. This case emphasizes that intensified prophylaxis for infections and less intense immunosuppression may be strategies to enable long-term survival in liver transplant recipients with common variable immunodeficiency and nodular regenerative hyperplasia relapse despite recently reported poor outcomes in this patient population.

Computer-assisted scoring is gaining prominence in the evaluation of renal histology; however, much of the focus has been on identifying larger objects such as glomeruli. Total inflammation impacts graft outcome, and its quantification requires tools to identify objects at the cellular level or smaller. The goal of the current study was to use CD45 stained slides coupled with image analysis tools to quantify the amount of non-glomerular inflammation within the cortex.

Sixty renal transplant whole slide images were used for digital image analysis. Multiple thresholding methods using pixel intensity and object size were used to identify inflammation in the cortex. Additionally, convolutional neural networks were used to separate glomeruli from other objects in the cortex. This combined measure of inflammation was then correlated with rescored Banff total inflammation classification and outcomes.

Identification of glomeruli on biopsies had high fidelity (mean pixelwise dice coefficient of .858). Continuous total inflammation scores correlated well with Banff rescoring (maximum Pearson correlation .
