Reliable localization and tracking of the eye region in the pediatric hospital environment is a significant challenge for clinical decision support and patient monitoring applications. Existing work in eye localization achieves high performance on adult datasets but performs poorly in the busy pediatric hospital environment, where face appearance varies because of age, position and the presence of medical equipment.

We developed two new datasets a training dataset using public image data from internet searches, and a test dataset using 59 recordings of patients in a pediatric intensive care unit. We trained two eye localization models, using the Faster R-CNN algorithm to fine-tune a pre-trained ResNet base network, and evaluated them using the images from the pediatric ICU.

The convolutional neural network trained with a combination of adult and child data achieved an 79.7% eye localization rate, significantly higher than the model trained on adult data alone. With additional pre-processing to equalize ke pediatric patient monitoring. The moderate size of our added training dataset shows that it is feasible to develop an internal training dataset for clinical computer vision applications, and apply it with transfer learning to fine-tune existing pre-trained models.
To understand if presence of mental stress-induced myocardial ischemia (MSIMI) is associated with higher prevalence of cognitive impairment at baseline and its decline over time.

A cohort of participants with stable coronary atherosclerosis underwent acute mental stress testing using a series of standardized speech/arithmetic stressors. The stress/rest digital vasomotor response to mental stress (sPAT) was assessed to measure microvascular constriction during mental stress. Patients received 99mTc-sestamibi myocardial perfusion imaging at rest, with mental stress and with conventional (exercise/pharmacological) stress. Cognitive function was assessed both at baseline and at a 2year follow-up using the Trail Making Test parts A and B and the verbal and visual memory subtests of the Wechsler Memory Scale.

We studied 486 individuals (72% male, 32.1% Black, 62±9 (mean±SD) years old). After multivariable adjustment for baseline demographics, risk factors, and medication use, presence of MSIMI was associated with 21% and 20% slower completion of Trail-A and Trail-B, respectively (p for all <0.01). After a 2-year follow-up period, presence of MSIMI was associated with a 33% slower completion of Trail-B, denoting cognitive decline (B=0.33, 95% CI, 0.04, 0.62). A lower sPAT, indicating greater vasoconstriction, mediated the association between MSIMI and worsening Trail-B performance by 18.2%. Ischemia with a conventional stress test was not associated with any of the cognitive tests over time.

MSIMI is associated with slower visuomotor processing and worse executive function at baseline and with greater decline in these abilities over time.

This review aimed at systematically evaluating the efficacy and safety of Yinqiao powder combined with western medicine in the treatment of pneumonia.

A systematic search for randomized controlled trials (RCTs) focusing on pneumonia treatment using a combination of Yinqiao powder and western medicine was performed in PubMed, the Cochrane Library, EMBASE, Web of Science, CNKI, Wanfang, Weipu (VIP) and CBM. The retrieval time limit was from the establishment of the database to June 2020. Two researchers independently screened the literature, extracted the data and evaluated the bias risk of the included studies. A meta-analysis was performed using RevMan5.3 software. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

Fifteen RCTs involving 1705 patients were included in the analysis. The meta-analysis results revealed the total effective rate of the treatment group [RR=1.21, 95% CI (1.15, 1.27), P<0.00001], bacterial clearance ue to the limitation of the quality and quantity of the included studies, more high-quality studies should be performed to verify our conclusions.
The current evidence indicated that the Yinqiao powder combined with western medicine can improve total efficiency in the treatment of pneumonia patients. The combination therapy performed better when compared to western medicine alone in the cooling time, bacterial clearance rate, T cell count, decline rates of CRP and PCT as well as in the incidences of adverse reactions. However, there was no significant difference in the decline rates of neutrophils and leucocytes between the two groups. The funnel plot, Egger's test and Begg's test indicated publication bias, which may be associated with unpublished negative study results. Due to the limitation of the quality and quantity of the included studies, more high-quality studies should be performed to verify our conclusions.Insomnia is common in patients with tinnitus and negatively affects tinnitus symptoms and quality of life. This systematic review aimed to synthesise evidence of the effectiveness of cognitive behavioural therapy (CBT) based interventions on insomnia in adults with tinnitus. We conducted a comprehensive database search (MEDLINE, CINAHL, Web of Science, CENTRAL, ClinicalTrials.gov and PROSPERO) for published, unpublished and ongoing randomised controlled trials of CBT in adults with tinnitus. Five trials met the inclusion criteria for the systematic review, with four of these providing data for the meta-analysis. This demonstrated a statistically significant reduction in Insomnia Severity Index (a standard diagnostic questionnaire of insomnia used in clinical settings) following CBT (-3.28, 95% CI -4.51, -2.05, P= less then 0.001). There was no evidence of statistical heterogeneity (I2 = 0%). Risk of bias was considered low in all categories except blinding of participants, personnel, and/or the assessment of outcomes. Here, for the first time, we demonstrate that CBT-based interventions can significantly improve sleep in adults with tinnitus.CRC is a heterogeneous disease due to global molecular alterations, including mismatch-repair-deficient (dMMR) and microsatellite instability-high (MSI-H). Immunotherapy has achieved durable responses in a subset of patients with dMMR-MSI-H metastatic CRC. It has been showed that Loss of ZG16 is highly associated with colorectal cancer. However, whether ZG16 modulates tumor immunity in colorectal cancer is unclear. In this study, we demonstrated that the expression of ZG16 is associated with distant metastasis and lymphatic invasive in colorectal cancer. Besides, ZG16 is negatively correlated to PD-L1 expression in patient with CRC and overexpression of ZG16 blocks PD-L1 expression in colorectal cancer cells. learn more In addition, overexpression of ZG16 promotes NK cells survival and proliferation, which is dependent on NKG2D expression. Our data demonstrate that ZG16 plays a role in modulation of immune response in colorectal cancer. The strong correlation between ZG16 and PD-L1 suggests that ZG16 may serve a biomarker to stratify patient who will benefit from immunotherapy.Neutron activation analysis is the reference method used for offline determination of the neutron flux density in defined positions. It can be used in the nuclear energy industry-as well as in medical- or space applications. For accurate neutron flux evaluation, well-known and reliable cross sections are needed. In the thermal and fast energy region, many reliable monitoring reactions exists, however, in case of the epithermal and intermediate energy region, there are practically no dosimetry nuclear reactions sensitive specifically in this energy range. Due to this fact, both new data are being measured and methodologies are under development to describe and test this energy region. It was found that various neutron filters can be used to cut parts of neutron spectra and thus methodology based on spectrum filtering could potentially be employed to survey cross sections of interest. It this paper, the use of 3 different filters - B4C, Cd, and In is studied, on the case of the 55Mn(n,γ) reaction. Measured values of that cross section in the given filtered reference spectra are reported.One of the commonly performed studies in nuclear medicine are bone scans with [99mTc]Tc-methylene diphosphonate (MDP) for detecting various bone lesions, including cancer metastasis. The recent emergence of commercially available 68Ge/68Ga radionuclide generators makes it possible to provide 68Ga-labelled bisphosphonates as positron emission tomography (PET) tracers for bone imaging. Preliminary human studies suggested that [68Ga]Ga-HBED-CC-BP ([68Ga]Ga-P15-041) in conjunction with PET/computed tomography (CT) showed accumulation in known bone lesions, fast clearance from blood and soft tissue, and an ability to provide high contrast images. A simple and efficient lyophilized P15-041 kit formulation for the rapid production of [68Ga]Ga-P15-041 with excellent radiochemical purity (RCP) under ambient temperature without the need for purification is described. link2 It is demonstrated that clinical doses of [68Ga]Ga-P15-041 can be prepared manually within minutes with an excellent purity (> 90%) and readily meet the dose release criteria. When [68Ga]Ga-P15-041 was evaluated in a patient with cancer, the imaging agent clearly showed accumulations in multiple lesions. In conclusion, [68Ga]Ga-P15-041, prepared by a lyophilized kit, might be an excellent bone imaging agent for widespread clinical application.We report an unusual case of synchronous papillary carcinoma of thyroglossal duct cyst (TGDC) and thyroid gland. Here, the radiology findings, surgical approach and subsequent management, and pathology of an synchronous papillary carcinoma of TGDC and thyroid gland are described.Extraskeletal Ewing sarcoma (EES) is a rare soft tissue tumor, and EES of the head and neck is particularly rare. Radiographic imaging of these lesions is crucial given their anatomical complexity and infrequent incidence. Conventional EES imaging features include a large, hyperintense, heterogeneously enhancing lesion, with frequent invasion of local structures. In this case report, a 19-year old male presented with left facial swelling and pain. He underwent sclerotherapy and bleomycin treatment for a presumed lymphatic malformation. link3 Initial imaging demonstrated a rim-enhancing lesion within the left buccal space with no muscle invasion or bony erosion present. Two years later, imaging identified an enlarging buccal mass with destruction of the zygomatic arch and inferolateral orbital wall. The patient underwent surgical resection of the mass. Pathology confirmed the mass to be a small round blue cell tumor and FISH testing confirmed the presence of the EWSR1 gene arrangement that is consistent with EES. The patient tolerated the procedure well and underwent chemoradiation therapy. At three years postoperatively, the patient remains disease free. The presented case demonstrates an unusual presentation of a buccal space EES as a rim-enhancing, centrally hypointense mass with no bony erosion or muscular invasion. The location and atypical imaging appearance of this case offer insight for future diagnosis of EES.
