Impairment of Executive Functions Associated With Lower D-Serine Serum Levels in Patients With Schizophrenia.

Front Psychiatry 2021 29;12:514579. Epub 2021 Mar 29.

Biomedical Research Center, University Hospital Hradec Kralove, Hradec Kralove, Czechia.

A core symptom that is frequently linked with dysregulation of glutamatergic neurotransmission in regard to schizophrenia is impairment or damage of executive functioning as a component of cognitive deficiency. The amino acid D-serine plays the role of an endogenous coagonist at the glutamatergic -methyl-D-aspartate (NMDA) receptor glycine modulatory site. Considerably reduced serum levels of D-serine were found in patients suffering from schizophrenia compared with healthy control participants. Read More

BH4-deficient hyperphenylalaninemia in Russia.

PLoS One 2021 6;16(4):e0249608. Epub 2021 Apr 6.

Research Centre for Medical Genetics, Moscow, Russia.

A timely detection of patients with tetrahydrobiopterin (BH4) -deficient types of hyperphenylalaninemia (HPABH4) is important for assignment of correct therapy, allowing to avoid complications. Often HPABH4 patients receive the same therapy as phenylalanine hydroxylase (PAH) -deficiency (phenylketonuria) patients-dietary treatment-and do not receive substitutive BH4 therapy until the diagnosis is confirmed by molecular genetic means. In this study, we present a cohort of 30 Russian patients with HPABH4 with detected variants in genes causing different types of HPA. Read More

Preoperative vitamin D deficiency is associated with increased risk of postoperative hypocalcemia after total thyroidectomy.

J Investig Med 2021 Mar 31. Epub 2021 Mar 31.

Department of Internal Medicine and Endocrinology, University of New Mexico Hospital, Albuquerque, New Mexico, USA.

Prior single-institution studies suggest that preoperative vitamin D deficiency (VDD) is associated with postoperative hypocalcemia and a prolonged length of hospital stay following total thyroidectomy. In this study, we employ a multi-institutional, de-identified electronic health records database to address this issue. We hypothesize that total thyroidectomy patients with preoperative VDD will be at an increased associated risk of postoperative hypocalcemia and hospitalization. Read More

Interstitial Lung Disease in Common Variable Immunodeficiency.

Front Immunol 2021 11;12:605945. Epub 2021 Mar 11.

Division of Clinical Immunology, Department of Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, United States.

Interstitial lung disease (ILD) is a common complication in patients with common variable immunodeficiency (CVID) and often associated with other features, such as bronchiectasis and autoimmunity. As the ILD term encompasses different acute and chronic pulmonary conditions, the diagnosis is commonly made based on imaging features; histopathology is less frequently available. From a cohort of 637 patients with CVID followed at our center over 4 decades, we reviewed the data for 46 subjects (30 females, 16 males) who had lung biopsies with proven ILD. Read More

Jonah Ventures, 5485 Conestoga Ct #210, Boulder, CO, 80301, USA.

North American plains bison (Bison bison) have been reintroduced across their former range, yet we know too little about their current diet to understand what drove their past migrations as well as observed continental-scale variation in weight gain and reproduction. In order to better understand the seasonal diets of bison at the continental scale, bison fecal material was collected monthly from April to September in 2019 across 45 sites throughout the conterminous United States. Fecal material was analyzed for dietary quality using near infrared spectroscopy and dietary composition with DNA metabarcoding. Read More

Simultaneous and proportional control of wrist and hand movements by decoding motor unit discharges in real time.

J Neural Eng 2021 Mar 24. Epub 2021 Mar 24.

Department of Mechanical Engineering, Shanghai Jiao Tong University State Key Laboratory of Mechanical System and Vibration, No. 800, Dongchuan Road, Shanghai, 200240, CHINA.

Surface electromyography (EMG) decomposition techniques can be used to establish human-machine interfacing (HMI), but most investigations are implemented offline due to the computational load of the approach. Here, we generalize the offline decomposition algorithm to identify the motor unit (MU) activities in real time, and we propose a MU-based approach for online simultaneous and proportional control of multiple motor tasks.High-density surface EMG signals recorded from forearm muscles were decomposed into motor unit spike trains (MUST) with the proposed decomposition method.
