The present invention provides a fully automatic controlled system, employed for the synthesis of L-6-[18F] Fluorodopa which is mainly used for the diagnosis of Parkinson's disease. 18F, an artificial radioisotope with half-life of 109.8 minutes, is obtained from deuteron bombardment of the neon gas, because of its labeled compound, [18F]-F-DOPA, having capability of penetrating through brain-blood-barrier, it can be utilized to evaluate dopamine metabolism and diagnose Parkinson's disease with PET scanner. The synthesis process of L-6-[18F] Fluorodopa include fluorination, evaporation of freon, hydrolysis, neutralization, separation and collection. The advantages of this automatic system are stability and reproductivity. Also, this system shortens the synthesis time and sequentially, elevates its production rate. Therefore, not only fewer technicians are needed for production, do they reduce exposure to radioactivity. In easy terms, the actual operation procedures of this system can be divided into three steps. First, put the raw material into designed reaction bottle. Afterward, turn on power button and reactive gas valve. Forty minutes after this button is turned on, L-6-[18F] Fluorodopa can be produced for clinical applications.
OBJECTIVES: I. Determine the maximum tolerated dose of gemcitabine in combination with radiation therapy to patients with locally advanced and/or unresectable adenocarcinoma of the pancreas. II. Determine the dose limiting toxic effects of this combination therapy in these patients. III. Evaluate the ability of these patients to tolerate induction and then maintenance therapy with gemcitabine preceding and following combination therapy. IV. Evaluate the efficacy (response rate, pattern of failure, and survival) of this combination therapy in these patients.

OUTLINE: This is a dose escalation study of gemcitabine. Part I: Patients receive gemcitabine as a continuous infusion over 30 minutes once weekly for 3 weeks followed by 1 week of rest. Part II: Gemcitabine IV is administered as a 30 minute infusion twice a week (Monday and Thursday) for 5-6 weeks. Patients receive radiation therapy 5 days a week for 5-6 weeks. In the absence of dose-limiting toxicity (DLT) in the first 6 patients treated, subsequent cohorts of 6 patients each receive escalating doses of gemcitabine on the same schedule. If DLT occurs in 2 of 6 patients at a given dose level, then dose escalation ceases and the next lower dose is declared the maximum tolerated dose. Part III: In the absence of toxicity and disease progression, patients continue gemcitabine for 3 additional courses. Maintenance gemcitabine starts 4 weeks after the completion of radiation therapy and is administered once weekly for 3 weeks followed by 1 week of rest. Patients are followed until death.

PROJECTED ACCRUAL: This study will accrue 15-30 patients in approximately 24 months.

An 80-year-old fit and active gentleman presented with left hip pain and a new central scotoma in his right eye after falling from an electric bicycle. He was able to mobilise independently and presented to ophthalmic services where cotton wool spots were found in both eyes and a presumptive diagnosis of Purtscher's retinopathy (PuR) was made. The patient was referred to the emergency department for assessment of a potential fracture. The subcapital femoral neck fracture was subtle on X-ray and only detected the following day with radiological and orthopaedic review. Two screws were placed to stabilise the fracture with a good outcome for his hip and for his vision. PuR can be seen following trauma to the head, neck or chest, following long bone fracture and in renal failure or pancreatitis. Our case highlights how the non-specific finding of cotton wool spots becomes a highly specific diagnosis in the context of trauma and should lead to careful evaluation for fractures.
OBJECTIVE: To detect key genes of local glucocorticoid therapy in oral lichen planus (OLP) through transcriptome sequencing.
METHODS: The study prospectively enrolled 28 symptomatic patients who visitied Department of Oral Mucosa, Peking University Hospital of Stomatology from November 2019 to March 2023. Topical inunction of 0.1 g/L of dexamethasone was applied for 1 min, 3 times daily for 4 weeks. The patients' signs and pain symptoms were recorded and they were classified as effective group and ineffective group according to the treatment outcome. Their mucosa samples were collected before treatment. After isolating total RNA, transcriptome sequencing was performed. The gene expression data obtained by sequencing were analyzed differently using the DESeq2 package in R software, and the Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis was performed on the basis of the hypergeometric distribution algorithm to describe the biological function of differentially expressed genes (DEGs), accordingly detecting sensitivity related molecular affecting therapeutic effect of dexamethasone.
RESULTS: After 4 weeks treatment by topical dexamethasone, 13 cases of the 28 OLP patients responding well with the sign score reducing from 7.0 (4.5, 9.0) to 5.0 (3.0, 6.3), pain score decreasing from 5.0 (2.0, 5.5) to 2.0 (0.0, 3.5), oral health impact profile lessening from 5.0 (3.5, 9.0) to 1.0 (0.0, 5.0) significantly (P<0.01) were classified as effective group and 15 cases with poor response to the drug were sorted as ineffective group. There were no significant differences of demographic and baseline levels of clinical features, especially disease severity between these two groups. A total of 499 DEGs including 274 upregulated and 225 downregulated genes were identified between effective group and ineffective group. KEGG enrichment analysis showed that upregulated genes in effective group compared with ineffective group including CLDN8, CTNNA3, MYL2 and MYLPF were associated with leukocyte transendothelial migration, while downregulated genes were significantly enriched in tumor necrosis factor (TNF), interleukin-17 (IL-17), nuclear factor kappa B (NF-κB) signaling pathways, and cortisol synthesis and secretory.
CONCLUSION: High expressions of CLDN8, CTNNA3, MYL2 and MYLPF genes in patients with oral lichen planus have a good clinical response to topical dexamethasone, while patients with high expression genes of inflammation pathway such as TNF, IL-17, NF-κB and cortisol synthesis and secretion received poor effect.
Then the therapist performs pressures in the transverse apophysis from D1 to D12 (level of the paravertebral muscles, at a distance of 2 fingers of the spinous apophysis), applying sustained pressure during expiratory time until the articulatory barrier is reached. Three repetitions are performed at each vertebral level. It is done bilaterally, then longitudinal pressures are applied on dorsal vertebrae during expiratory time, 3 repetitions. It ends like treatment 1. This technique aims to normalize possible slight dysfunctions of the spine, enhance the feeling of comfort and pain, and relax the spine. Duration of the treatment is 15 minutes.
Dozee VS device is intended for the contactless continuous monitoring of vital parameters (Heart Rate and Respiratory Rate), and screening for abnormal changes in these parameters. The device is intended to be used to monitor individuals/patients greater than eighteen (18) years of age (40 kg ≤ weight ≤ 120 kg) and can measure their vital signs during sleep and resting state. The data can be viewed on the dashboard, exported and even be directly transferred to the in-house hospital management software. This protocol aims at verifying the safety and effectiveness of the investigational device in a general-care clinical environment. A similar predicate can be found in the FDA-cleared EarlySense 2.0 (K131379) developed by EarlySense Ltd which shall be used as the predicate device. The device also uses the concept of ballistocardiography and employs piezoelectric sensors to create a contact-less continuous monitoring system which monitors the same vital parameters. It has been sold in over 20 U.S. hospitals since 2013, with no recalls or adverse events reported. According to publicly available clinical results, this system has shown an 86% reduction in Code Blue events, and a 45% reduction in Length of Stay (LoS) in the ICU for patients coming from the medical/surgical unit. The technology employed and the indications for use for the EarlySense device is very similar to the Dozee VS device.
This is a prospective, multicenter database that will be populated by sites utilizing N-13 Ammonia and sponsored by Ionetix. Each site with access to N-13 produced under an investigational new drug (IND) application will be eligible to participate. Once the site is activated, the site will enroll patients into the database that are scheduled for clinically indicated PET-MPI with N-13 (as determined by their treating physicians). PET-MPI perfusion, MBF, percent ischemia, pharmacologic stress agent, and gated left ventricular ejection fraction/function values will be collected when available, in an anonymous fashion and uploaded into the database. All patient health identifiers (PHI) will be removed prior to upload. No procedures additional to those clinically indicated will be performed for the purposes of this study.
Oral leukoplakia (OLK) is the most representative oral potentially malignant disorder, with a high risk of malignant transformation and unclear mechanisms of occurrence. Recently, photodynamic therapy (PDT) has exhibited great potential in the treatment of OLK. However, the efficacy of PDT is difficult to predict and varies from person to person. Ferroptosis-related pathways are upregulated in many cancers, and ferroptosis induction is considered to be a potential synergistic strategy for various antitumor therapies, but its role in OLK treatment remains unclear. This study aimed to determine whether ferroptosis induction can enhance the efficacy of PDT in OLK treatment. Our study revealed that solute carrier family 7 member 11 (SLC7A11), a component of a crucial amino acid transporter and a key negative regulator of ferroptosis, was found to be highly expressed in OLK patients with no response to PDT. 5-Aminolevulinic acid (ALA)-PDT is known to cause apoptosis and necrosis, but ferroptosis also occurred under ALA-PDT in OLK cells in our study. Using erastin to induce ferroptosis enhanced the efficacy of ALA-PDT on OLK cells by disrupting the antioxidant system and further elevating intracellular reactive oxygen species levels, leading to increased apoptosis. Furthermore, this combined modality also enhanced the efficacy of ALA-PDT on 4-nitroquinoline-1-oxide (4NQO)-induced OLK lesions in mice. In summary, ferroptosis induction may serve as a potential strategy to enhance the efficacy of ALA-PDT for OLK treatment.
This arm will follow a BABA sequence. "A" representing ON beta blockers and "B" representing OFF of beta blockers. Subjects in this arm will have their previously prescribed beta blocker dose reduced until they are completely off of beta blockers during Period 1. They will then crossover into Period 2, where uptitration will begin until they are back on their previously prescribed dose of beta blockers. After Period 2, the subjects have the option to decide if they want to be on or off their beta blocker and proceed with the Follow-Up Phase, or continue to Period 3 if they don't feel ready to make that decision to stay on or go off their beta blocker yet. During Period 3, we will again conduct a dose reduction, until the subject is off of beta blockers. Finally, during Period 4, we will up-titrate them back to their home dose of beta blockers.

It is a open-label single-arm clinical trial. Outcome measurement is the positivity rate of Ga68-PSMA-11 PET-defined progression and Bone Scan-defined progression. The primary objective is to compare the diagnostic positivity in progression of PSMA PET and BS. The 2×2 contingency table with four diagnostic outcomes (both positive, PET positive/BS negative, PET negative/BS positive, and both negative) will be conducted based on the enrolled subjects. Both diagnostic tools (Ga68-PSMA-11 PET and BS) are applied to a given set of individuals. Since both diagnostic tools will performed on each subject, then paired data result and methods that account for the correlated binary outcomes are necessary. McNemar's test will be used to compare the positivity of the two tools. Assuming that Ga68-PSMA-11 PET in patients detect more metastatic lesions/progression by 26.5% (i.e. p10-p01=0.265) and the discordant percentage is 38.5 % (i.e. p10+p01=0.385). Under the hypothesis H0: p10=p01, achieving an 80% power at the 5% of significance level, the sample size is 44. Based on expecting 15% of missing rate, the adjusted sample size will be 52. This calculation was done by PASS software (Power Analysis and Sample Size version 11.0.8, NCSS, Kaysville, Utah, USA).

For PET/CT PSMA scan, the subject will have catheter(s) placed for intravenous administration of \[68Ga\]PSMA-11. Subjects will receive a single intravenous bolus of 2-5 mCi \[68Ga\]PSMA-11 and received PET/CT scan 60 minutes later. PSMA PET-CT scan was performed on a GE Discovery MI PET/CT system. The CT scan parameters were 120 kVp, 30 mA to 300 mA acquired with auto mA , 40× 0.625 collimator configuration, and pitch of 0.984 : 1. All images were reconstructed with a 500 mm field of view and a slice thickness of 5 mm. The PET acquisition time was 3 mins per bed position with maximum overlap (35 slices). Images were reconstructed using Q clear with beta value of 550, PSF correction, and non-TOF (QCHD-S). The matrix is 256 × 256. After image acquisition, the subject will be observed for half an hour, and will be discharged if no adverse event happens. EKG, blood and biochemistry test will be performed before and after first PET scan no more than two weeks. Except baseline Ga68-PSMA-11 PET/CT scan, patients will receive serial PET scans after 3rd injection of Ra-233 and 6th injection of Ra-223. All of the images were interpreted by an experienced nuclear medicine physicians.
To perform taping of the chest, the patient was asked to stand upright with the affected shoulder rotated externally. Five straps of the fan shaped tape were extended to the chest toward the affected axilla with 15% to 20% tension, and the anchor was positioned without tension in the anterior axilla on the sound side.
BACKGROUND: Post-stroke fatigue (PSF) affects 50% of stroke survivors. Current guidance on management of this condition is limited.
AIMS: This systematic review and meta-analysis aimed to identify and analyze all randomized clinical trials (RCTs) of non-pharmacological interventions for the treatment of PSF.
SUMMARY OF REVIEW: Six electronic databases were searched from inception to January 2023 for English-language RCTs investigating the efficacy of non-pharmacological interventions versus passive controls in patients with PSF. The primary outcome was fatigue severity at the end of the intervention. The Cochrane risk-of-bias (ROB)2 tool was used to assess evidence quality. A total of 7990 records were retrieved, 333 studies were scrutinized, and 13 completed RCTs (484 participants) were included. Interventions included psychological therapies, physical therapies, and brain stimulation. Nine studies provided sufficient data for meta-analysis, of which seven also had follow-up data. Fatigue severity was lower in the intervention groups at the end of the intervention compared with control (participants = 310, standardized mean difference (SMD) = -0.57, 95% confidence intervals (CIs) (-0.87 to -0.28)) and at follow-up (participants = 112, SMD = -0.36, 95% CIs (-0.83 to 0.10)). Certainty in the effect estimate was downgraded to low for a serious ROB and imprecision. Subgroup analysis revealed significant benefits with physical therapy and brain stimulation but not psychological therapies, though sample sizes were low.
CONCLUSION: Non-pharmacological interventions improved fatigue but the quality of evidence was low. Further RCTs are needed for PSF management.
Symptoms may include: mask-like facies; drooling, tremors; pill-rolling motion; cogwheel rigidity; and shuffling gait. Reassurance and sedation are important. In most cases, these symptoms are readily controlled when an anti-parkinsonism agent is administered concomitantly. Anti-parkinsonism agents should be used only when required. Generally, therapy of a few weeks to two to three months will suffice. After this time patients should be evaluated to determine their need for continued treatment. (Note: Levodopa has not been found effective in pseudo-parkinsonism.) Occasionally it is necessary to lower the dosage of trifluoperazine HCl or to discontinue the drug.
The immune-fibrosis axis plays a critical role in cardiac remodeling after acute myocardial infarction. Imaging approaches to monitor temporal inflammation and fibroblast activation in mice have seen wide application in recent years. However, the repeatability of quantitative measurements remains challenging, particularly across multiple imaging centers. We aimed to determine reproducibility of quantitative inflammation and fibroblast activation images acquired at 2 facilities after myocardial infarction in mice. Methods: Mice underwent coronary artery ligation and sequential imaging with 68Ga-DOTA-ECL1i to assess chemokine receptor type 2 expression at 3 d after myocardial infarction and 68Ga-FAPI-46 to assess fibroblast activation protein expression at 7 d after myocardial infarction. Images were acquired at 1 center using either a local or a consensus protocol developed with the second center; the protocols differed in the duration of isoflurane anesthesia and the injected tracer dose. A second group of animals were scanned at the second site using the consensus protocol. Image analyses performed by each site and just by 1 site were also compared. Results: The uptake of 68Ga-DOTA-ECL1i in the infarct territory tended to be higher when the consensus protocol was used (P = 0.03). No difference was observed between protocol acquisitions for 68Ga-FAPI-46. Compared with the local protocol, the consensus protocol decreased variability between individual animals. When a matched consensus protocol was used, the 68Ga-DOTA-ECL1i infarct territory percentage injected dose per gram of tissue was higher on images acquired at site B than on those acquired at site A (P = 0.006). When normalized to body weight as SUV, this difference was mitigated. Both the percentage injected dose per gram of tissue and the SUV were comparable between sites for 68Ga-FAPI-46. Image analyses at the sites differed significantly, but this difference was mitigated when all images were analyzed at site A. Conclusion: The application of a standardized acquisition protocol may lower variability within datasets and facilitate comparison of molecular radiotracer distribution between preclinical imaging centers. Like clinical studies, multicenter preclinical studies should use centralized core-based image analysis to maximize reproducibility across sites.
The invention relates to application of alpha2-3 neuraminidase in induction of transplantation immune tolerance. The invention relates to a neuraminidase, namely alpha2-3 Neuraminidase (alpha2-3Neu for short), which is one of several kinds of neuraminidases, is a high-specification exoglycosidase, and mainly catalyzes the hydrolysis of an alpha2-3 glucosidic bond. The pretreatment of the alpha2-3Neu at proper concentration can obviously enhance the affinity of donor Bone Marrow Cells (dBMCs) and liver, and the dBMCs which are peripherally intravenously infused are distributed in the receptor liver in a targeted way and can form a hematopoietic cell colony. When a receptor has been infused with the dBMCs of a pretreatment group of the alpha2-3Neu at the proper concentration for 15 days, typical sex determining gene (SRY) sequences of Y chromosomes of a donor can be detected in most receptors, which indicates that the pretreatment of the alpha2-3Neu more easily induces the formation of chimerism. The dBMCs pretreated by the alpha2-3Neu, combining CyclosporinA (CsA), can obviously prolong the survival time of a skin graft of the donor. The alpha2-3Neu has good induction effect in transplantation immune tolerance.
