Virtual Coach-Guided Online Acceptance and Commitment Therapy for Chronic Pain: Pilot Feasibility Randomized Controlled Trial.

Background: Veterans are disproportionately affected by chronic pain, with high rates of pain diagnoses (47%-56%) and a 40% higher rate of prevalence of severe pain than nonveterans. This is often accompanied by negative functional outcomes and higher mortality. Combined with research suggesting medical treatments for chronic pain are often insufficient, there is an urgent need for nonmedical pain self-management programs.

Stepwise Functional Brain Architecture Correlates with Atrophy in Progressive Supranuclear Palsy.

Background: Stepwise functional connectivity (SFC) detects whole-brain functional couplings of a selected region of interest at increasing link-step topological distances.

Objective: This study applied SFC to test the hypothesis that stepwise architecture propagating from the disease epicenter would shape patterns of brain atrophy in patients with progressive supranuclear palsy-Richardson's syndrome (PSP-RS).

Methods: Thirty-six patients with PSP-RS and 44 age-matched healthy control subjects underwent brain magnetic resonance imaging on a 3-T scanner.

Lipschütz ulcers due to SARS-CoV-2 infection: a neglected diagnosis in emergency room.

Background: Primary acute genital ulcers, or Lipschütz ulcers (LU), are nonsexually transmitted, painful, self-limiting, nonrecurrent vulvar ulcers with unclear pathogenesis, representing a challenging diagnosis in emergency setting. LU have recently been described in association with severe acute respiratory syndrome coronaVirus 2 (SARS-CoV-2) infection and vaccination.

Objective: The aim of this study is to describe 2 cases of LU due to SARS-CoV-2 infection, highlighting the diagnostic process, differential diagnosis, disease course, and management options.

Dual-task gait training improves cognition and resting-state functional connectivity in Parkinson's disease with postural instability and gait disorders.

Objectives: To assess whether dual-task gait/balance training with action observation training (AOT) and motor imagery (MI) ameliorates cognitive performance and resting-state (RS) brain functional connectivity (FC) in Parkinson's disease (PD) patients with postural instability and gait disorders (PIGD).

Methods: 21 PD-PIGD patients were randomized into 2 groups: (1) DUAL-TASK + AOT-MI group performed a 6-week training consisting of AOT-MI combined with practicing observed-imagined gait and balance exercises; and (2) DUAL-TASK group performed the same exercises combined with landscape-videos observation. At baseline and after training, all patients underwent a computerized cognitive assessment, while 17 patients had also RS-fMRI scans.

Impact of Socio-Demographic Attributes and Mutual Gaze of Virtual Humans on Users' Visual Attention and Collision Avoidance in VR.

This study investigated the extent that the non-verbal behaviors of virtual humans (VHs) and their socio-demographic attributes altered users' collision avoidance behaviors in Virtual Reality (VR). Users interacted with VHs representing different levels of ethnicities and gender, exhibiting different conditions of physical movement, and gaze behaviors. The VHs were depicted in three major ethnic conditions namely Asian, Caucasian, and Black.

Action observation and motor imagery improve motor imagery abilities in patients with Parkinson's disease - A functional MRI study.

Introduction: Motor imagery (MI) skills can be affected in Parkinson's disease (PD). We aimed at assessing MI and brain functional changes after action observation and MI training (AOT-MI) associated with gait/balance exercises in PD patients with postural instability and gait disorders (PD-PIGD).

Methods: Twenty-five PD-PIGD patients were randomized into two groups: DUAL-TASK + AOT-MI group performed 6-week gait/balance training combined with AOT-MI; DUAL-TASK group performed the same exercises without AOT-MI.

Propranolol for the treatment of infantile hemangiomas: a nine-year monocentric experience from a tertiary hospital.

Background: Propranolol is currently considered the first-line therapy for problematic infantile hemangiomas (IH), the most common benign vascular neoplasm of infancy.

Objectives: We present a retrospective observational study aimed at assessing the efficacy of propranolol in 44 IH patients.

Materials & Methods: A nine-year retrospective review considering clinicodemographical and therapy-related variables was performed on medical records of infants treated for IH with oral propranolol.

New insights into the molecular basis of spinal neurofibromatosis type 1.

Spinal neurofibromatosis (SNF) is a form of neurofibromatosis type 1 (NF1) characterized by bilateral neurofibromas involving all spinal roots. The pathogenic mechanisms determining the SNF form are currently unknown. To verify the presence of genetic variants possibly related to SNF or classic NF1, we studied 106 sporadic NF1 and 75 SNF patients using an NGS panel of 286 genes encoding RAS pathway effectors and neurofibromin interactors and evaluated the expression of syndecans (SDC1, SDC2, SDC3, SDC4), the NF1 3' tertile interactors, by quantitative real-time PCR.

Gender differences in microRNA expression in levodopa-naive PD patients.

Gender is an important factor influencing epidemiological and clinical features of Parkinson's disease (PD). We aimed to evaluate gender differences in the expression of a panel of miRNAs (miR-34a-5p, miR-146a, miR-155, miR-29a, miR-106a) possibly involved in the pathophysiology or progression of disease. Serum samples were obtained from 104 PD patients (58 men and 46 women) never treated with levodopa.

An Online Acceptance and Mindfulness Intervention for Chronic Pain in Veterans: Development and Protocol for a Pilot Feasibility Randomized Controlled Trial.

Background: In the veteran community, chronic pain is particularly prevalent and often debilitating. Until recently, veterans with chronic pain were offered primarily pharmacological intervention options, which rarely suffice and can also have negative health consequences. To better address chronic pain in veterans, the Veterans Health Administration has invested in novel, nonpharmacological behavior interventions that target both pain management and chronic pain-related functional issues.

Cerebellar alterations in Parkinson's disease with postural instability and gait disorders.

Background: Few studies interrogated the involvement of cerebellum in modulating gait in Parkinson's disease (PD) patients with postural instability and gait disorders (PD-PIGD). This study aimed at assessing cerebellar atrophy and activity alterations during functional MRI (fMRI) gait-simulating motor- and dual-tasks in PD-PIGD.

Methods: Twenty-one PD-PIGD and 23 healthy controls underwent clinical assessment, structural MRI, and fMRI including a motor-task (foot anti-phase movements) and a dual-task (foot anti-phase movements while counting backwards by threes).

Comparative analysis of detoxification-related gene superfamilies across five hemipteran species.

Background: Hemiptera is one of the most speciose orders of insects, and the most speciose considering Hemimetabola. Through their evolutive history, hemipterans with different feeding habits have adapted to deal with different chemical challenges. Three major gene families are involved in xenobiotic detoxification in insects: the cytochromes P450 (CYPs), carboxyl/cholinesterases (CCEs), and glutathione transferases (GSTs).

A monolateral pigmented lesion of the nipple.

Pigmented mammary Paget's disease is a very rare variant of mammary Paget's disease linked to an underlying carcinoma in almost all cases. We present the case of a 62-year-old female patient who came to our attention for the evaluation of a monolateral asymptomatic pigmented lesion of the right nipple, which turned out to be a pigmented mammary Paget's disease unassociated to an underlying malignancy - an extremely rare entity only anecdotally reported in literature. The two main peculiarities of our patient's lesion, the importance of immunohistochemistry in the differential diagnosis and the theories on its pathogenesis are discussed.
