TL;DR: In a young woman with clinical evidence of acute cutaneous, musculoskeletal, and neurologic manifestations of systemic lupus erythematosus, computed tomography (CT) showed enlarged, centrally hypoattenuating mesenteric and retroperitoneal lymph nodes.
Abstract: In a young woman with clinical evidence of acute cutaneous, musculoskeletal, and neurologic manifestations of systemic lupus erythematosus, computed tomography (CT) showed enlarged, centrally hypoattenuating mesenteric and retroperitoneal lymph nodes. After treatment with steroids, the CT appearance of the lymph nodes returned to normal. The differential diagnosis of lymph nodes with central hypoattenuation includes Mycobacterium tuberculosis infection, metastatic disease (especially squamous cell carcinoma and germ cell tumor), Whipple's disease, and celiac disease in addition to lupus lymphadenitis.

TL;DR: It is doubtful FM sonography will be widely used unless it is at least as useful as conventional (AM) sonography in all common applications.
Abstract: A new type of ultrasound signal processing (“FM sonography”) appears to be beneficial compared to conventional ultrasound (“AM sonography”) in some applications (e.g., diffuse liver disease and prostatic carcinoma). Despite these possible advantages, it is doubtful FM sonography will be widely used unless it is at least as useful as conventional (AM) sonography in all common applications.
Fifty-five patients with suspected gallbladder disease were independently evaluated with both AM and FM sonography. The two modalities were blindly and prospectively compared for accuracy in detecting gallstones and for image quality. No statistically significant difference was found between images produced by FM and conventional signal processing. FM had an accuracy of detecting gallstones of 98.1%, compared to 96.2% for AM. Overall, FM accuracy was 97.7%, while AM had an overall accuracy of 97.3%. Other useful sonographic signs were evaluated (gallbladder wall thickness, diameter of common duct). No AM/FM difference was noted.
Our data suggest that FM-only imaging could be performed in patients with suspected gallbladder disease without loss of accuracy.

TL;DR: In this article, the authors highlight six areas of innovation that have the potential to reduce the burden of diabetes for individuals living with the condition and their families as well as provide measurable benefits for all stakeholders involved in diabetes care.
Abstract: The digital health revolution is transforming the landscape of medicine through innovations in sensor data, software, and wireless communication tools. As one of the most prevalent chronic diseases in the United States, diabetes is particularly impactful as a model disease for which to apply innovation. As with any other newly developed technologies, there are three key questions to consider: 1) How can the technology benefit people with diabetes?, 2) What barriers must be overcome to further advance the technology?, and 3) How will the technology be applied in the future?. In this article, we highlight six areas of innovation that have the potential to reduce the burden of diabetes for individuals living with the condition and their families as well as provide measurable benefits for all stakeholders involved in diabetes care. The six technologies which have the potential to transform diabetes care are (i) telehealth, (ii) incorporation of diabetes digital data into the electronic health record, (iii) qualitative hypoglycemia alarms, (iv) artificial intelligence, (v) cybersecurity of diabetes devices, and (vi) diabetes registries. To be successful, a new digital health technology must be accessible and affordable. Furthermore, the people and communities that would most likely benefit from the technology must be willing to use the innovation in their management of diabetes.

TL;DR: Initial hemodynamic patterns are associated with final outcome in patients with severe head injuries and further studies are warranted to investigate whether treatment guided by such information can improve survival.
Abstract: Secondary brain insults influence outcome significantly in patients with severe head injuries. Inadequate tissue perfusion should be identified and treated early to avoid such insults. Conventional hemodynamic monitoring (blood pressure, heart rate, urine output) is not a reliable method for evaluating circulatory function in such patients. Invasive monitoring by means of pulmonary artery catheters may offer more precise information on early circulatory abnormalities. The objective of this study was to study the hemodynamic patterns of patients with severe closed head trauma by invasive methods and to correlate the derived information with survival. Fifty-nine consecutive patients with blunt trauma, closed head injuries, and Glascow Coma Scale < 8 were studied. Pulmonary artery catheters were placed in all patients shortly after admission, and flow and flow-derived variables were monitored for 96 hours or patient demise. Survivors had higher cardiac index, oxygen delivery, and oxygen consumption values compared to nonsurvivors during the first 24 hours after injury. Following this period increased values were recorded in both groups. These temporal hemodynamic patterns were similar for patients with isolated head trauma and patients with other associated injuries. Thus initial hemodynamic patterns are associated with final outcome in patients with severe head injuries. Aggressive early hemodynamic monitoring may reveal subtle but significant changes. Further studies are warranted to investigate whether treatment guided by such information can improve survival.

TL;DR: Investigation of the Rose Questionnaire for prediction of outcome in patients with suspected myocardial infarction indicated that subjects with positive questionnaires were less likely to have infarctions confirmed at discharge, except for those with a prior history of myocardia.
Abstract: The Rose Questionnaire, developed to facilitate screening for the presence of coronary artery disease, has shown good utility for white men and more variable utility among Latino, African-American, and female subjects. This study investigated its utility for prediction of outcome in patients with suspected myocardial infarction. A total of 1428 white, Latino, and African-American subjects completed questionnaires after emergency admission, which were correlated with diagnoses at the time of discharge from a public hospital and private hospital. Results indicated that subjects with positive questionnaires were less likely to have infarction confirmed at discharge, except for those with a prior history of myocardial infarction, than those with a negative response. These data are important in evaluating the overall utility of the Rose Questionnaire and the significance of angina.
