Inflammatory bowel disease (IBD) is a complex, immune-mediated gastrointestinal disorder with ill-defined etiology, multifaceted diagnostic criteria, and unpredictable treatment response. Innovations in IBD diagnostics, including developments in genomic sequencing and molecular analytics, have generated tremendous interest in leveraging these large data platforms into clinically meaningful tools. Artificial intelligence, through machine learning facilitates the interpretation of large arrays of data, and may provide insight to improving IBD outcomes. While potential applications of machine learning models are vast, further research is needed to generate standardized models that can be adapted to target IBD populations. 相似文献
Aim: The aim of this study was to assess the effect of different orthodontic treatment needs on the OHQoL of adolescents. Materials and methods: 200 subjects (100 males and 100 females), 11 to 15 years of age were recruited for the study. OHQoL was assessed with the short form of the oral health impact profile (OHIP-14), and malocclusion severity was assessed with the index of orthodontic treatment need (IOTN). The Chi-square test was used to analyse the qualitative data. The level of significance was 0.05. Results: The more severe the malocclusion the worse was the impact on the OHQoL. Orthodontic treatment need had almost similar impact on the daily activities of both males and females. Pronunciation and taste was not significantly affected by the need for orthodontic treatment in either males or females. The proportions of orthodontic patients who found it uncomfortable to eat any food and had to interrupt their meals were significantly correlated with orthodontic treatment needs in both males and females. Conclusion: Orthodontic treatment need had an impact on OHQoL of adolescents with no significant difference between males and females. Clinical significance: Orthodontists should be aware of the impact caused by malocclusion and orthodontic treatment on the quality of life of the patients and should provide regular positive reinforcements to them.

The number of African Americans (AAs) on the kidney waiting list is increasing in the United States. Several studies showed that AAs are at higher risk for rejection and graft loss. Because of genetic polymorphisms, AAs may metabolize calcineurin inhibitors faster than Caucasian (C) individuals. The goal of this study is to evaluate the tacrolimus (TAC) dose required to reach therapeutic levels and to assess the impact of clotrimazole on TAC metabolism in AAs compared to C patients. One hundred forty-two AA renal transplant recipients (RTRs) were compared to 309 C RTRs. Demographics were similar in both groups. Induction therapy and maintenance immunosuppression were similar in both groups and included TAC, mycophenolate acid (MPA), and steroids. The goal in all RTRs was to maintain a 12-hour trough level of 10 to 15 ng/mL in the first 3 months, 8 to 10 ng/mL for the first year, and 5 to 8 ng/mL thereafter. To achieve these levels, AA RTRs require a significantly higher dosage of TAC compared to C patients (5.9 ± 2.9 vs 3.6 ± 2 mg/d, respectively, P < .0001). By multivariate analysis, TAC dose requirements were not affected by age, gender, MPA or prednisone dose, diabetes, and renal function. Adding clotrimazole (CTM) to the RTR regimen significantly reduced the TAC dose requirements in all RTRs. When CTM was used, the TAC dose requirement was not statistically significantly different between AA and C patients (2.6 ± 1.2 mg/d vs 1.8 ± 1.5 mg/d, P = .07). We conclude that AAs required a higher TAC dose to reach the desired trough level in RTRs compared to C RTRs. The use of CTM eliminates the need for higher doses of TAC in AA RTRs. Thus, CTM may aid AA RTRs in achieving therapeutic TAC levels while reducing drug costs. 相似文献
We describe a 26-year-old woman who was diagnosed eleven years ago with systemic lupus erythematosus and who had suffered multiple relapses. She presented with class IV lupus nephritis with thrombotic microangiopathy, for which she received three doses of rituximab along with plasmapheresis, with no response, and soon became dialysis dependent. One month after the last dose of rituximab, she presented with dyspnoea and hypoxia. A transbronchial lung biopsy revealed pulmonary fibrosis. A diagnosis of rituximab induced pulmonary fibrosis was made after excluding other causes and she was treated with intravenous methyl prednisolone with which there was marked improvement in symptoms and hypoxemia. This is the first report of rituximab induced pulmonary fibrosis in a patient with lupus nephritis. 相似文献
Microparticles (MPs) are small membrane-bound vesicles that arise from activated and dying cells and enter the blood to display pro-inflammatory and pro-thrombotic activities. MPs are 0.1-1.0 μm in size and incorporate nuclear, cytoplasmic and membrane molecules as they detach from cells. This process can occur with cell activation as well as cell death, with particles likely corresponding to blebs that form on the cell surface during apoptosis. To measure particle expression, flow cytometry allows determination of particle numbers based on size as well as surface markers that denote the cell of origin; platelet MPs are usually the most abundant type in blood. As shown in in vitro and in vivo systems, MPs can promote inflammation and thrombosis resulting from their content of cytokines like IL-1 and pro-coagulant molecules like tissue factor. Certain particle types can be anti-inflammatory, however, suggesting a range of immunomodulatory activities depending on the cell of origin. Studies on patients with a wide range of rheumatic disease show increased MP numbers in blood, with platelet and endothelial particles associated with vascular manifestations; increased numbers of particles also occur in the joint fluid where they may drive cytokine production and activate synoviocytes. In autoimmune diseases such as SLE and RA, MPs may also contribute to disease pathogenesis by the formation of immune complexes. MPs thus represent novel subcellular structures that can impact on the pathogenesis of rheumatic disease and serve as biomarkers of underlying cellular disturbances. 相似文献

To describe the demographics, clinical features, and treatment outcomes with systemic steroids in eyes presenting with post-fever retinitis (PFR) from Central India.
Methods
Single-center, retrospective analysis of 147 eyes of 98 PFR cases between 2011 and 2019.
Results
Mean age of the study cohort was 33.46?±?12.76 years, with 72 males and 26 females. The mean interval between the onset of fever and the diminution of vision was 21.10?±?13.54 days (range 0–60 days). The number of PFR cases increased over the nine years with 89 cases (90.1%) presenting during winters. Unilateral involvement was seen in 49 cases, while 49 had bilateral involvement. Clinical characteristics included: multifocal retinitis (n?=?122; 61.2%), hemorrhages (n?=?132; 89.8%), disc edema (n?=?57; 38.8%), anterior chamber reaction (n?=?28; 19%), and vitritis (n?=?103; 70.1%). Treatment included intravenous followed by oral steroids in 70 patients and oral steroids exclusively in 23; five patients denied treatment. The visual acuity improved from 1.09?±?0.52 LogMAR to 0.29?±?0.42 LogMAR (p?<?0.05).
Conclusion
There has been an increase in the prevalence of PFR cases over the last decade with clustering during the winters. Multifocal retinitis, retinal hemorrhages, and vitritis were the most common clinical findings in our series. The retinitis resolved with improvement in vision following steroid therapy in all eyes.
Color vision deficiency (CVD) is a condition that results in individuals being unable to distinguish differences between certain colors. Occupational color vision standards were introduced in aviation in 1919 by The Aeronautical Commission of the International Civil Air Navigation Authority. Concern has been expressed during the last few years that the current color vision standards in aviation may be too stringent and, at the same time, also variable across the world. The tests employed do not always reflect the tasks pilots encounter in today’s aviation environment. This ambiguity leads to the possible exclusion of deserving applicants for selection as aircrew. The compatibility of CVD with aircraft crew is assessed by medical personnel using clinical diagnosis tests on the ground level. These clinical tests were developed specifically to detect the presence, nature, and severity of CVD. No clinical tests yet provide a measure of operational performance in operating an aircraft. Arbitrary pass marks have been assigned to clinical tests such that a failing candidate will either be subject to operational restrictions or excluded completely. The prescribed clinical tests and associated pass marks vary considerably between regulators. While an individual may be subject to no restrictions in one jurisdiction, they may be excluded in another. This article highlights newer diagnostic techniques adopted by different countries for assessing color vision to see for the scope of evidence-based guidelines for minimum color vision requirements for flight crew as well as for civil aviation in India. 相似文献
