A novel concept of the heterophase optics-electronics synergistic effect has been demonstrated in a single-layer α/δ-heterophase perovskite CsPbI3 in order to realize white LEDs featuring only one broadband emissive layer.BACKGROUND There have been few studies to evaluate early warning score (EWS) systems, or track and trigger systems (TTS), to identify early clinical deterioration in patients following brain tumor surgery who are admitted to the Intensive Care Unit (ICU). The National Early Warning Score (NEWS2) is an established method used in the U.K. National Health Service to improve care for in-hospital patients. This retrospective study from a single center aimed to compare the performance of NEWS2 with 24 other types of EWS to evaluate unplanned ICU admissions within 72 h after brain tumor surgery. MATERIAL AND METHODS A total of 326 patients with brain tumors were included in the study. Patients who experienced unplanned ICU transfer after surgery (69 cases) were diagnostically matched with patients who did not require intensive care (257 controls). We collected the physiological variables to calculate the area under the receiver operator characteristic curve (AUROC), sensitivity, specificity, Youden index values, cutoff values, positive predictive values, and negative predictive values. RESULTS The NEWS2 identified postoperative brain tumor patients with AUROC (0.860, p=0.000). The Patient-At-Risk (PAR) score was higher than NEWS2 in terms of AUROC value (0.870, P=0.000), Youden index (0.589 vs 0.542). CONCLUSIONS The findings showed that although the NEWS 2 performed well when used to evaluate unplanned ICU admissions within 72 h of postoperative brain tumor patients, the PAR score was also an accurate EWS.BACKGROUND Serratia marcescens infections have historic association with injection drug use. The present report is about a 53-year-old man with a history of intravenous (IV) drug use who presented with acute loss of vision due to endophthalmitis associated with disseminated S. marcescens infection. CASE REPORT A 53-year-old man with a history of active illicit IV drug use presented with a chief complaint of loss of vision in his left eye for 5 days. He also reported having a fever, chills, and shortness of breath. While in the Emergency Department, he became hypotensive and hypoxic. He needed to be intubated and was started on vasopressor support. An ophthalmological examination was suspicious for endophthalmitis. The patient underwent a vitreous tap with injection of intravitreal antibiotics on the day of admission. An echocardiogram showed severe tricuspid endocarditis requiring valve replacement. He also was found to have a left lung/pleural abscess, which was surgically drained. Later, a left eye vitrectomy was performed and the intravitreal antibiotics were repeated; the treatment was unsuccessful and enucleation eventually was required. In addition, the patient had gastric bleeding and underwent esophagogastroduodenoscopy, which showed ischemic stomach ulcers suggestive of septic emboli. Cultures of the patient's blood, tricuspid valve, lung abscess, and vitreous fluid revealed S. marcescens. He was treated long term with a 2-drug antibiotic regimen and discharged in stable condition. CONCLUSIONS We have presented a rare case of acute loss of vision due to endophthalmitis in a patient with a history of IV drug use, which was associated with disseminated infection with the Gram-negative saprophyte S. marcescens.BACKGROUND Patient knowledge gaps about the evaluation and waitlisting process for kidney transplantation lead to delayed and incomplete testing, which compromise transplant access. We aimed to develop and evaluate a novel video education approach to empower patients to proceed with the transplant evaluation and listing process and to increase their knowledge and motivation. MATERIAL AND METHODS We developed 2 theory-informed educational animations about the kidney transplantation evaluation and listing process with input from experts in transplantation and communication, 20 candidates/recipients, 5 caregivers, 1 anthropologist, 3 community advocates, and 36 dialysis or transplant providers. We then conducted an online pre-post study with 28 kidney transplantation candidates to measure the acceptability and feasibility of the 2 videos to improve patients' evaluation and listing knowledge, understanding, and concerns. RESULTS Compared with before intervention, the mean knowledge score increased after intervention by 38% (5.7 to 7.9; P90% of responses indicated positive ratings on trusting the information, comfort level with learning, and engagement. CONCLUSIONS In partnership with stakeholders, we developed 2 educational animations about kidney transplant evaluation and listing that were positively received by patients and have the potential to improve patient knowledge and understanding and reduce patient concerns.Department of Radiology, Mazumdar Shaw Medical Centre - Narayana Multispecialty Hospital, Narayana Health, Estimation of quantity and rate of bleeding is of great value in the management of patients with acute GI bleed. Endoscopy and multiphase contrast enhanced computed tomography (MCECT) are the presently employed two important methods for this purpose. Still there is a lacuna in the methods of precise estimation of amount of bleed, which at the moment are somewhat unreliable and subjectively evaluated. learn more We present the value of dynamic contrast-enhanced CT examination in quantitatively estimating the amount of extravasated blood with the help of three illustrative clinical examples. Technique CT examination, the methodology for assessment of quantity of bleed is presented and the discussion of existing literature regarding the estimation methods is presented.Bommasandra, Bengaluru, India.We present a rare case of a fistula between a pancreatic pseudocyst and the bile duct with saccular dilatation that appeared to be a type I choledocal cyst. There are only 19 described cases in the consulted bibliography. The patient was studied with an ultrasound, CT and MRCP and later surgically intervened. A resection was performed of the extrahepatic biliary and hepaticojejunostomy. There was a subsequent good evolution.
