Spatial Network Connectivity and Spatial Reasoning Ability in Children with Nonverbal Learning Disability.

Nonverbal Learning Disability (NVLD) is characterized by deficits in visual-spatial, but not verbal, reasoning. Nevertheless, the functioning of the neural circuits supporting spatial processing have yet to be assessed in children with NVLD. We compared the resting state functional connectivity of a spatial brain network among children with NVLD, children with reading disorder (RD), and typically developing (TD) children.

Altered network connectivity predicts response to cognitive-behavioral therapy in pediatric obsessive-compulsive disorder.

Obsessive-compulsive disorder (OCD) is commonly associated with alterations in cortico-striato-thalamo-cortical brain networks. Yet, recent investigations of large-scale brain networks suggest that more diffuse alterations in brain connectivity may underlie its pathophysiology. Few studies have assessed functional connectivity within or between networks across the whole brain in pediatric OCD or how patterns of connectivity associate with treatment response.

Interpersonal Violence and Maxillofacial Fractures.

Purpose: Accident Compensation Corporation statistics shows that maxillofacial fracture affects 11,000 people with an approximate $90 million annual cost in New Zealand dollars (NZD). Previous studies have demonstrated interpersonal violence (IPV), road traffic accidents (RTAs), sports injury, and falls being the common causes of maxillofacial fracture. This study investigated the causes and associated alcohol and/or drug use and fracture patterns in patients presenting with maxillofacial fractures in the Wellington region.

Structural neural markers of response to cognitive behavioral therapy in pediatric obsessive-compulsive disorder.

Background: Cognitive behavioral therapy (CBT) is an effective, first-line treatment for pediatric obsessive-compulsive disorder (OCD). While neural predictors of treatment outcomes have been identified in adults with OCD, robust predictors are lacking for pediatric patients. Herein, we sought to identify brain structural markers of CBT response in youth with OCD.

Panel 4: Recent advances in understanding the natural history of the otitis media microbiome and its response to environmental pressures.

Objective: To perform a comprehensive review of otitis media microbiome literature published between 1 July 2015 and 30th June 2019.

Data Sources: PubMed database, National Library of Medicine.

Review Methods: Key topics were assigned to each panel member for detailed review.

Mechanical properties of the shoulder and pectoralis major in breast cancer patients undergoing breast-conserving surgery with axillary surgery and radiotherapy.

Breast-conserving surgery (BCS) and radiotherapy reduce breast cancer recurrence but can cause functional deficits in breast cancer survivors. A cross-sectional study quantified the long-term pathophysiological impact of these treatments on biomechanical measures of shoulder stiffness and ultrasound shear wave elastography measures of the shear elastic modulus of the pectoralis major (PM). Nine node-positive patients treated with radiotherapy to the breast and regional nodes after BCS and axillary lymph node dissection (Group 1) were compared to nine node-negative patients treated with radiotherapy to the breast alone after BCS and sentinel node biopsy (Group 2) and nine healthy age-matched controls.

Expression of Cathepsins B, D, and G by the Embryonic Stem Cell-Like Population within Human Keloid Tissues and Keloid-Derived Primary Cell Lines.

Background: The authors have previously shown that an embryonic stem cell-like population within keloid-associated lymphoid tissues in keloid lesions expresses components of the renin-angiotensin system that may be dysregulated. The authors hypothesized that cathepsins B, D, and G are present within the embryonic stem cell-like population in keloid lesions and contribute to bypass loops of the renin-angiotensin system.

Methods: 3,3'-Diaminobenzidine immunohistochemical staining for cathepsins B, D, and G was performed on formalin-fixed paraffin-embedded sections in keloid tissue samples of 11 patients.

A comprehensive district-level laboratory intervention after the Ebola epidemic in Sierra Leone.

Background: The 2014-2016 Ebola outbreak exposed the poor laboratory systems in Sierra Leone. Immense needs were recognised across all areas, from facilities, diagnostic capacity, supplies, trained personnel to quality assurance mechanisms.

Objective: We aimed to describe the first year of a comprehensive intervention, which started in 2015, in a public hospital's general laboratory serving a population of over 500 000 in a rural district.

A guide to architecture for the public health workforce.

Background: Public health and environmental challenges facing the world in the 21st century, including the ageing population, increasing urbanisation, rise of non-communicable diseases and climate instability, require an interdisciplinary response. A significant proportion of the population's time is spent indoors, be it at home, school, work or in leisure time; the work of an architect can cover all of these sectors, but their role in health and well-being remains an under explored area.

Objective: This article examines the architecture profession's potential to contribute to improved health and well-being of the population through healthier buildings and places.

Parental involvement in decision making about intracranial pressure monitor placement in children with traumatic brain injury.

Objective: Little is known about how parents of children with traumatic brain injury (TBI) participate or feel they should participate in decision making regarding placing an intracranial pressure (ICP) monitor. The objective of this study was to identify the perspectives and decisional or information needs of parents whose child sustained a TBI and may require an ICP monitor.

Methods: This was a qualitative study at one US level I pediatric trauma center.

Identification of Racial Inequities in Access to Specialized Inpatient Heart Failure Care at an Academic Medical Center.

Background: Racial inequities for patients with heart failure (HF) have been widely documented. HF patients who receive cardiology care during a hospital admission have better outcomes. It is unknown whether there are differences in admission to a cardiology or general medicine service by race.

Brain Volume Abnormalities in Youth at High Risk for Depression: Adolescent Brain and Cognitive Development Study.

Objective: Children of parents with depression are two to three times more likely to develop major depressive disorder than children without parental history; however, subcortical brain volume abnormalities characterizing major depressive disorder risk remain unclear. The Adolescent Brain and Cognitive Development (ABCD) Study provides an opportunity to identify subcortical differences associated with parental depressive history.

Method: Structural magnetic resonance data were acquired from 9- and 10-year-old children (N = 11,876; release 1.

APOL1-Associated Collapsing Focal Segmental Glomerulosclerosis in a Patient With Stimulator of Interferon Genes (STING)-Associated Vasculopathy With Onset in Infancy (SAVI).

Apolipoprotein L1 (APOL1) risk variants G1 and G2 are known to result in risk for kidney disease in patients of African ancestry. APOL1-associated nephropathy typically occurs in association with certain environmental factors or systemic diseases. As such, there has been increasing evidence of the role of interferon (IFN) pathways in the pathogenesis of APOL1-associated collapsing glomerulopathy in patients with human immunodeficiency virus (HIV) infection and systemic lupus erythematosus, 2 conditions that are associated with high IFN levels.

The Multi-Scale, Three-Dimensional Nature of Skeletal Muscle Contraction.

Muscle contraction is a three-dimensional process, as anyone who has observed a bulging muscle knows. Recent studies suggest that the three-dimensional nature of muscle contraction influences its mechanical output. Shape changes and radial forces appear to be important across scales of organization.

Pathologic Response to Primary Systemic Therapy With FOLFIRINOX in Patients With Resectable Pancreatic Cancer.

Background: Primary systemic therapy in resectable pancreatic cancer is currently under investigation. FOLFIRINOX has been shown to be effective in both the adjuvant and metastatic settings and is increasingly being used on and off study in the neoadjuvant setting. The objective pathologic response elicited by this regimen in truly resectable disease has not as yet been widely reported.

Clinical Assessment of 5-Fluorouracil/Leucovorin, Nab-Paclitaxel, and Irinotecan (FOLFIRABRAX) in Untreated Patients with Gastrointestinal Cancer Using Genotype-Guided Dosing.

Purpose: 5-Fluorouracil (5-FU)/leucovorin, irinotecan, and nab-paclitaxel are all active agents in gastrointestinal cancers; the combination, FOLFIRABRAX, has not been previously evaluated. UDP Glucuronosyltransferase 1A1 (UGT1A1) clears SN-38, the active metabolite of irinotecan. polymorphism reduces UGT1A1 enzymatic activity and predisposes to toxicity.

Task-based fMRI predicts response and remission to exposure therapy in obsessive-compulsive disorder.

Exposure and ritual prevention (EX/RP) is an effective first-line treatment for obsessive-compulsive disorder (OCD), but only some patients achieve minimal symptoms following EX/RP. Herein, we investigate whether task-based neural activity can predict who responds best to EX/RP. Unmedicated adult patients with OCD ( = 36) and healthy participants ( = 33) completed the Simon Spatial Incompatibility Task during high-resolution, multiband functional MRI (fMRI); patients were then offered twice-weekly EX/RP (17 sessions).

TNFR2 induced priming of the inflammasome leads to a RIPK1-dependent cell death in the absence of XIAP.

The pediatric immune deficiency X-linked proliferative disease-2 (XLP-2) is a unique disease, with patients presenting with either hemophagocytic lymphohistiocytosis (HLH) or intestinal bowel disease (IBD). Interestingly, XLP-2 patients display high levels of IL-18 in the serum even while in stable condition, presumably through spontaneous inflammasome activation. Recent data suggests that LPS stimulation can trigger inflammasome activation through a TNFR2/TNF/TNFR1 mediated loop in xiap macrophages.

Warm bodies, cool wings: regional heterothermy in flying bats.

Many endothermic animals experience variable limb temperatures, even as they tightly regulate core temperature. The limbs are often cooler than the core at rest, but because the large locomotor muscles of the limbs produce heat during exercise, they are thought to operate at or above core temperature during activity. Bats, small-bodied flying mammals with greatly elongated forelimbs, possess wings with large surfaces lacking any insulating fur.

Cancer stem cell subpopulations in primary colon adenocarcinoma.

Aims: The cancer stem cell concept proposes that tumor growth and recurrence is driven by a small population of cancer stem cells (CSCs). In this study we investigated the expression of induced-pluripotent stem cell (iPSC) markers and their localization in primary low-grade adenocarcinoma (LGCA) and high-grade adenocarcinoma (HGCA) and their patient-matched normal colon samples.

Materials And Methods: Transcription and translation of iPSC markers OCT4, SOX2, NANOG, KLF4 and c-MYC were investigated using immunohistochemical (IHC) staining, RT-qPCR and in-situ hybridization (ISH).

Antibody deficiency testing for primary immunodeficiency: A practical review for the clinician.

Objective: To review selected published studies related to the diagnostic evaluation of antibody deficiency.

Data Sources: Published literature.

Study Selections: Studies related to the diagnostic evaluation of antibody deficiency and existing recommendations were selected.

CD38CD8 T Cells Associated with the Development of Acute GVHD Are Activated, Proliferating, and Cytotoxic Trafficking Cells.

We have previously reported that a peripheral blood absolute CD38CD8 effector memory T cell (TEM) population expansion of >35 cells/µL predicts the development of acute graft-versus-host disease (GVHD). We hypothesized that these T cells are activated, proliferating, and cytotoxic trafficking cells that are not a response to viral reactivation and may be involved in acute GVHD. We characterized peripheral blood T cell populations at the time of maximum CD38CD8 TEM expansion in patients from our originally reported pediatric allogeneic hematopoietic cell transplantation recipient cohort.

The CuePed Trial: How Does Environmental Complexity Impact Cue Effectiveness? A Comparison of Tonic and Phasic Visual Cueing in Simple and Complex Environments in a Parkinson's Disease Population with Freezing of Gait.

Background: The optimal prescription of cueing for the treatment of freezing of gait (FoG) in Parkinson's disease (PD) is currently a difficult problem for clinicians due to the heterogeneity of cueing modalities, devices, and the limited comparative trial evidence. There has been a rise in the development of motion-sensitive, wearable cueing devices for the treatment of FoG in PD. These devices generally produce cues after signature gait or electroencephalographic antecedents of FoG episodes are detected (phasic cues).
