Background: Substantial evidence links loneliness to poor academic outcomes and poor employment prospects. Schools have been shown to be places that mitigate or aggravate loneliness, suggesting a need to consider how schools can better support youth experiencing loneliness.

Methods: We conducted a narrative review on loneliness in childhood and adolescence to examine the literature on how loneliness changes over the school years and how it influences learning.

Temporary Assistance for Needy Families (TANF) is a federal cash welfare program for low-income, working families with children in the United States that requires participation with child support enforcement, if one parent is noncustodial, to receive the cash benefit. Cash assistance has been linked to improved child health and academic achievement, but sanctions to benefits can increase health risks. Our community-engaged, mixed-methods research project sought to identify barriers to TANF among families with young children in Illinois.

Communication across membranes controls critical cellular processes and is achieved by receptors translating extracellular signals into selective cytoplasmic responses. While receptor tertiary structures can be readily characterized, receptor associations into quaternary structures are challenging to study and their implications in signal transduction remain poorly understood. Here, we report a computational approach for predicting receptor self-associations, and designing receptor oligomers with various quaternary structures and signaling properties.

Avascular necrosis (AVN), one of the most common therapy-related and debilitating side effects of antileukemic treatment, can adversely affect a patient's long-term quality of life. Our case study presents a young woman with bilateral elbow AVN and hip AVN after acute lymphoblastic leukemia treatment, with a unique treatment strategy for her elbow pain. The treatment strategy included elbow joint denervation with arthroscopic debridement and distal humerus core decompression.

Purpose: Digit replantation can improve dexterity, functionality, patient satisfaction, and pain following amputation, but rates continue to fall nationally. This study aimed to describe the effects of travel time and distance as barriers to high-volume hospitals, identify geospatial inefficiencies in the presentation of patients to replantation care, and provide an optimal allocation model in which cases are redistributed to select centers to reduce geospatial redundancies and optimize outcomes.

Methods: We reviewed the California Office of Statewide Health Planning and Development hospital discharge database to identify cases of digital amputation and determine outcomes of replantation.

CRISPR-Cas9 is a revolutionary technology because it is precise, fast and easy to implement, cheap and components are readily accessible. This versatility means that the technology can deliver a timely end product and can be used by many stakeholders. In plant cells, the technology can be applied to knockout genes by using CRISPR-Cas nucleases that can alter coding gene regions or regulatory elements, alter precisely a genome by base editing to delete or regulate gene expression, edit precisely a genome by homology-directed repair mechanism (cellular DNA), or regulate transcriptional machinery by using dead Cas proteins to recruit regulators to the promoter region of a gene.

Hydrodynamic attractors have recently gained prominence in the context of early stages of ultrarelativistic heavy-ion collisions at the RHIC and LHC. We critically examine the existing ideas on this subject from a phase space point of view. In this picture the hydrodynamic attractor can be seen as a special case of the more general phenomenon of dynamical dimensionality reduction of phase space regions.

Panniculectomy is an increasingly common operation, given the current obesity epidemic and the increasing prevalence of bariatric surgery. At first glance, it could be considered a technically simple operation; however, this procedure can be fraught with complications, given the patient population and high demands placed on compromised abdominal tissue. Sufficient attention must be given to the nuances of patient optimization and surgical planning to maximize safe and ideal outcomes.

Background: Juvenile forms of parkinsonism are rare conditions with onset of bradykinesia, tremor and rigidity before the age of 21 years. These atypical presentations commonly have a genetic aetiology, highlighting important insights into underlying pathophysiology. Genetic defects may affect key proteins of the endocytic pathway and clathrin-mediated endocytosis (CME), as in DNAJC6-related juvenile parkinsonism.

Dicobalt edetate and hydroxocobalamin are widely used to treat hydrogen cyanide poisoning. However, comparative and quantitative efficacy data are lacking. Although post-exposure treatment is typical, it may be possible to administer these antidotes before exposure to first attenders entering a known site of cyanide release, as supplementary protection to their personal protective equipment.

Early efforts to understand complexity in field theory have primarily employed a geometric approach based on the concept of circuit complexity in quantum information theory. In a parallel vein, it has been proposed that certain deformations of the Euclidean path integral that prepare a given operator or state may provide an alternative definition, whose connection to the standard notion of complexity is less apparent. In this Letter, we bridge the gap between these two proposals in two-dimensional conformal field theories, by explicitly showing how the latter approach from path integral optimization may be given by a concrete realization within the standard gate counting framework.

We apply the recently developed notion of complexity for field theory to a quantum quench through a critical point in 1+1 dimensions. We begin with a toy model consisting of a quantum harmonic oscillator, and show that complexity exhibits universal scalings in both the slow and fast quench regimes. We then generalize our results to a one-dimensional harmonic chain, and show that preservation of these scaling behaviors in free field theory depends on the choice of norm.

Lack of physician familiarity with alternative pain control strategies is a major reason why opioids remain the most commonly used first-line treatment for pain after surgery. This is perhaps most problematic in abdominal wall reconstruction, where opioids may delay ambulation and return of bowel function, while negatively affecting mental status. In this article, we discuss multimodal strategies for optimal pain control in abdominal wall reconstruction.

Article Synopsis
  • ClC chloride channels and transporters play a crucial role in maintaining chloride balance across various organisms, including humans, and mutations in these proteins can lead to inherited diseases.
  • Researchers studied the unfolding process of the ClC transporter from Escherichia coli (ClC-ec1) using single-molecule techniques and discovered that the protein can be split into two independently unfolding halves.
  • This finding supports the idea that the two parts of the ClC protein may have evolved from separate folding units that fused together, suggesting that having smaller, less complex folding domains can help prevent misfolding in larger membrane proteins.
