In this work, we develop a novel approach to cross-view gait recognition with the view angle of a probe gait sequence unknown. We formulate a Gaussian Process (GP) classification framework to estimate the view angle of each probe gait sequence. To measure the similarity of gait sequences captured at different view angles, we model the correlation of gait sequences from different views using Canonical Correlation Analysis (CCA) and use the correlation strength as similarity measure. This differs significantly from existing approaches, which reconstruct gait features in different views either through 2D view transformation or 3D calibration. Without explicit reconstruction, our approach can cope with feature mis-match across view and is more robust against feature noise. Our experiments validate that the proposed method significantly outperforms the existing state-...

The patient presents with local and/or radicular pain, followed by loss of sensory, motor, bladder, and bowel function. Case Report: A 25-year-old patient presented with left-sided weakness preceded by nontraumatic upper back pain. He denied any past medical illness and being on any regular medications. He had decreased strength in the left lower limb, left upper limb, and right lower limb, with intact strength in the right upper limb. The patient exhibited decreased sensation of pain and touch on the right side of the lower limb, bilateral loss of proprioception, and intact reflexes and anal tone. He had weakness on the left side of the body and contralateral decreased sensation of pain and touch on the right side. These symptoms were suggestive of Brown-Séquard syndrome, while the bilateral loss of proprioception suggested posterior cord syndrome. Magnetic resonance imaging showed an acute spinal subdural canal hematoma producing cord compression. The patient had an urgent laminectomy and hematoma evacuation. Afterward, his neurological function improved. Conclusions: Spontaneous spinal subdural hematoma can occur without any known pathology or remarkable trauma. It can compress the spinal cord and produce cerebral stroke-like symptoms. Hence, spinal hematoma should be ruled out in any patient presenting with a neurological deficit.

It does not display any structural cardiac abnormalities. It was first described in 1992, as the syndrome of ‘right bundle branch block, persistent ST segment elevation, and sudden death.’ Brugada phenocopy (BP) is a relatively new term used to describe electrocardiogram (ECG) patterns that resemble BS but are due to other reversible causes such as electrolyte abnormalities, fever, cocaine or alcohol intoxication, and side effect of certain medications such as sodium channel blockers, beta blockers, antidepressants, alpha adrenergic blockers, etc. Earlier studies have shown that patients taking sodium channel blocking antiepileptic drugs (AEDs) especially phenytoin can have Brugada type 1 like ECG pattern. Previously, type 2 ECG pattern secondary to supra-therapeutic phenytoin level has not been described. We describe a case with type 2 Brugada ECG pattern due to supra-therapeutic phenytoin level;...

It is most common in patients with solid tumors.[1][2][3] Tumor lysis syndrome is a metabolic and oncologic emergency frequently encountered in clinical practice. This condition is prevalent in both adult and pediatric oncology patients undergoing chemotherapy. Most of the symptoms seen in patients with tumor lysis syndrome are related to the release of intracellular chemical substances that causes impairment to the functions of target organs. This can lead to acute kidney injury (AKI), fatal arrhythmia, and even death. This condition is the most common oncological emergency. Cancer is a leading cause of morbidity and mortality in the United States and the second leading cause of death. Cancer, as a disease entity, has a wide range ...

However the early detection of breast cancer is dependent on both radiologist’s ability to read mammograms and the quality of mammograms images. Mammography is the effective technique for the screening of breast cancer and abnormalities detection. Screening is one of the key factor to reduce the death rates. The strong correlation between abnormalities and breast cancer shows that radiologists could get benefit by the CAD (Computer aided Diagnosis) system with abilities of automated breast tissue classification. The aim of this paper is to present a survey of existing mammograms, enhancement and segmentation techniques, with the clear classification and analysis of each technique.

Methods Retrospective data was collected for 1181 patients admitted to the largest hospital in Qatar with COVID-19 pneumonia. The area under the curve (AUC), calibration curves, and other metrics were bootstrapped to examine the performance of the models. Variables constituting the CURB-65 and PSI scores underwent further analysis using the Least Absolute Shrinkage and Selection Operator (LASSO) along with logistic regression to develop a model predicting CCI. Complex machine learning models were built for comparative analysis. Results The PSI performed better than CURB-65 in predicting 30-day mortality (AUC 0.83, 0.78 respectively), while CURB-65 outperformed PSI in predicting CCI (AUC 0.78, 0.70 respectively). The modified PSI/CURB-65 model (respiratory rate, oxygen saturation, hematocrit, age, sodium, and glucose) predicting CCI had excellent accuracy (AUC 0.823) and good calibration. Conclusions Our study recalibrated, externally validated the PSI and CURB-65 for predicting 30-day mortality and CCI, and developed a model for predicting CCI. Our tool can potentially guide clinicians in Qatar to stratify patients with COVID-19 pneumonia.

Scanning electron microscopy displayed mostly polyhedral shapes with no surface fractures. XRD displayed characteristic A type pattern and decrease in per cent crystallinity (22.53–20.41%) was observed as the dose increased from 5 to 20 kGy. DPPH % inhibition and FRAP values were increased in a dose dependent manner. Pasting properties (peak, final and setback viscosity) decreased with irradiation. Pasting temperature also significantly decreased with irradiation for all the irradiated starches. The transition temperatures, enthalpy of gelatinization, pH and apparent amylose content of starch decreased significantly with increase in irradiation dose.

The incidence of hypernatremia is higher in ambulatory peritoneal dialysis (PD) than in hemodialysis (HD) patients. In PD patients it is often a result of excessive ultrafiltration but in HD it is often a result of dialysate composition errors. Dialysate composition errors can inadvertently cause either hyponatremia or hypernatremia. We present two cases of symptomatic hypernatremia which manifested as increased thirst, excessive weight gain and worsening hypertension in HD patients. The hypernatremia was caused by a combination of errors in online conductivity reading and a faulty hand held conductivity meter. Symptoms were relieved in both patients after replacement of the dialysis machine.

Results showed that the proximate composition of the flour did not change significantly. However, pasting properties showed a significant (p 0.05) decrease in peak viscosity, final viscosity, setback viscosity, trough viscosity and pasting temperature as the dosage increased. Swelling, syneresis and solubility improved with dosage. Oil absorption capacity and water absorption capacity increased significantly with dosage from 1.03 to 1.45 and 1.56e2.63 g/g of flour respectively. pH decreased significantly with dosage. Gelatinization temperature increased, while as enthalpy decreased significantly. Texture profile properties also decreased with dosage.
