BACKGROUND: Primary care providers are well positioned to respond to the opioid crisis by providing buprenorphine/naloxone (B/N) through shared medical appointments (SMA). While quantitative research has been previously conducted on SMAs with B/N, we conducted a qualitative assessment from the patients' point of view, considering whether and how group visits provide value for patients. METHODS: Twenty-five participants with opioid use disorder (OUD) who were enrolled in a weekly B/N group visit at a family medicine clinic participated in either of two one-hour-long focus groups, which were conducted as actual group visits...

BACKGROUND: Conservative treatment in spine deformities and spine related disorders is mainly based on proper individual proprioceptive and motor control training. For these reasons, conservative treatment involves the stimulation of individual capability of perceiving/reducing deformities, blocks and/or improper spine posture by voluntary control. The literature describes that habitually adopted relaxed postures often exacerbate low back pain. Typically, youths can be referred to therapeutic programs aimed at improving the quality of body posture along with fostering the awareness of the importance of correct posture...

M-type (Kv7, KCNQ) potassium channels are proteins that control the excitability of neurons and muscle cells. Many physiological and pathological mechanisms of excitation operate via the suppression of M channel activity or expression. Conversely, pharmacological augmentation of M channel activity is a recognized strategy for the treatment of hyperexcitability disorders such as pain and epilepsy. However, physiological mechanisms resulting in M channel potentiation are rare. Here we report that intracellular free zinc directly and reversibly augments the activity of recombinant and native M channels...

RNA editing is a post-transcriptional process that alters the nucleotide sequence of RNA transcripts to generate transcriptome diversity. Among the various types of RNA editing, adenosine-to-inosine (A-to-I) RNA editing is the most frequent type of RNA editing in mammals. Adenosine deaminases acting on RNA (ADAR) enzymes, ADAR1 and ADAR2, convert adenosines in double-stranded RNA structures into inosines by hydrolytic deamination. Inosine forms a base pair with cytidine as if it were guanosine; therefore, the conversion may affect the amino acid sequence, splicing, microRNA targeting, and miRNA maturation...

We report on a theoretical study of the spin Hall Effect (SHE) and weak antilocalization (WAL) in graphene/transition metal dichalcogenide (TMDC) heterostructures, computed through efficient real-space quantum transport methods, and using realistic tight-binding models parametrized from ab initio calculations. The graphene/WS2 system is found to maximize spin proximity effects compared to graphene on MoS2, WSe2, or MoSe2, with a crucial role played by disorder, given the disappearance of SHE signals in the presence of strong intervalley scattering...

Humans have 4 million exocrine sweat glands, which can be classified into two types: eccrine and apocrine glands. Sweat secretion is a constitutive feature, which is directly involved in thermoregulation and metabolism. Sweat secretion is regulated by both the central nervous system(1) and autonomic nervous system.(2) In peripheral areas, the ANS, especially the sympathetic nervous system (SNS), mediates the transmission of neurotransmitters to sweat glands. Two principal chemical mediators, acetylcholine and noradrenaline (NA)/adrenaline (ADR), are released by the SNS, which stimulate sweat secretion...

The microtubule (MT)-associated protein Tau is a natively unfolded protein, involved in a number of neurodegenerative disorders, collectively called tauopathies, aggregating in neurofibrillary tangles (NFT). It is an open question how the conversion from a MT bound molecule to an aggregation-prone Tau species occurs and, also, if and how tauopathy-related mutations affect its behavior in the cell. To address these points, we exploited a genetically encoded FRET sensor based on the full length Tau protein, to monitor in real time Tau conformational changes in different conditions in live cells...

Although members of the Association for Behavioral and Cognitive Therapies have made significant strides toward the collective goals outlined in our mission statement, we routinely acknowledge that our ability to develop empirically supported treatments exceeds our success in improving dissemination and implementation of said interventions. Further, as noted by Kazdin and Blase (2011), even if we succeeded in having every clinician worldwide administer our best treatments with excellent competency, we still would be unsuccessful in markedly impacting the worldwide burden of mental illness because most treatments require intensive labor by expensive providers...

Anticipatory processing, maladaptive attentional focus, and postevent processing are key cognitive constructs implicated in the maintenance of social anxiety disorder (SAD). The current study examined how treatment for SAD concurrently affects these three cognitive maintaining processes and how these processes are associated with each other as well as with symptom change from pre- to posttreatment. The sample consisted of 116 participants with SAD receiving group cognitive behavioral therapy. All three cognitive maintaining processes were measured relative to a speech task and again relative to a conversation task...

Many neurodegenerative disorders, including Alzheimer's, Parkinson's and the prion diseases, are characterized by a conformational conversion of normally soluble proteins or peptides into pathological species, by a process of misfolding and self-assembly that leads ultimately to the formation of amyloid fibrils. Recent studies support the idea that multiple intermediate species with a wide variety of degrees of neuronal toxicity are generated during such processes. The development of a high level of knowledge of the nature and structure of the pathogenic amyloid species would significantly enhance efforts to underline the molecular origins of these disorders and also to develop both accurate diagnoses and effective therapeutic interventions for these types of conditions...

Dopamine-β-hydroxylase (DBH, EC 1.14.17.1), an oxido-reductase that catalyses the conversion of dopamine to norepinephrine, is largely expressed in sympathetic neurons and adrenal medulla. Several regulatory and structural variants in DBH associated with various neuropsychiatric, cardiovascular diseases and a few that may determine enzyme activity have also been identified. Due to paucity of studies on functional characterization of DBH variants, its structure-function relationship is poorly understood. The purpose of the study was to characterize five non-synonymous (ns) variants that were prioritized either based on previous association studies or Sorting Tolerant From Intolerant (SIFT) algorithm...

Aplastic anemia (AA) is nowadays considered to be a clonal disorder arising from a defective hematopoietic stem cell developing after a generalized insult to bone marrow. Immunosuppressive treatment (IST) of AA causes suppression of the target dominant population of haematopoietic cells allowing the defective non targeted clones to expand. This may give rise to acute leukemia. Cytogenetic studies for chromosomal aberrations such as trisomy and monosomy may help in detecting such conversions. We present a case of acquired AA in a 60-year-old male presenting with pancytopenia and hypoplastic marrow treated with antithymocyte globulin, converting into myelodysplastic syndrome and later on acute promyelocytic leukemia after being in remission for 4 years...

BACKGROUND: Schizophrenia (SCH) and depression (DEP) are prevalent psychiatric disorders and share common and distinguished elements in their pathophysiology. A triple network model composed of the default mode network (DMN), salience network (SN) and central executive network (CEN) may represent a major abnormality across several psychiatric disorders including SCH and DEP. However, common and distinct dysfunctional patterns between SCH and DEP across three core networks remain unclear...

Hypertensive disorder in pregnancy (HDP) refers to a series of diseases that cause the hypertension during pregnancy, including HDP, preeclampsia (PE) and eclampsia. This study screens differentially expressed proteins of placenta tissues in PE cases using 2D LC-MS/MS quantitative proteomics strategy. A total of 2281 proteins are quantified, of these, 145 altering expression proteins are successfully screened between PE and control cases (p<0.05). Bioinformatics analysis suggests that these proteins are mainly involved in many biological processes, such as oxidation reduction, mitochondrion organization, and acute inflammatory response...

BACKGROUND: Eating problems in patients with advanced dementia are strongly associated with their deteriorating survival. Food and drink intake in people with dementia may be supported by specific interventions, but the effectiveness of such interventions is backed by almost no evidence. However, comprehensive geriatric assessment (CGA) might potentially clarify the etiology of decreased oral intake in people with dementia; thus improving their clinical outcomes. METHODS: This study was a single-arm, non-randomized trial that included historically controlled patients for comparison...

OBJECTIVE: Previous studies provide mixed evidence that physical activity engagement (PAE) in adolescence is associated with later mental health outcomes. This study aimed to examine the association between PAE at age 14 and mental health outcomes at age 21 using a large birth cohort study. MATERIAL AND METHODS: Prospective data from the Mater-University of Queensland Study of Pregnancy, consisting of 3493 young adults, were analyzed. PAE at age 14 was estimated using self-report, and participants were categorized into; (1) frequent, (2) infrequent, or (3) no PAE group...

Phosphoglucomutase 3 (PGM3) protein catalyzes the conversion of N-acetyl-d-glucosamine-6-phosphate (GlcNAc-6-P) to N-acetyl-d-glucosamine-1-phosphate (GlcNAc-1-P), which is required for the synthesis of uridine diphosphate N-acetylglucosamine (UDP-GlcNAc) an important precursor for protein glycosylation. Mutations in PGM3 gene have been recently shown to underlie a new congenital disorder of glycosylation often associated to elevated IgE. Herein, we report twelve PGM3 deficient patients. They belong to three highly consanguineous families, originating from a rural district in the west central Tunisia...
