Childhood Respiratory Illnesses Before and After COVID-19 Pandemic Restrictions.

Introduction With the COVID-19 pandemic, multiple studies described a significant drop in common respiratory viruses in children with the lockdown and restrictions. With the lifting of pandemic precautions, we had the ability to observe new patterns of respiratory illnesses in children and emergency department visits. Materials and methods We studied all respiratory nucleic acid amplification test results in emergency patients from a large metropolitan children's hospital from the years 2018 to 2023.

Thalamocortical control of cell-type specificity drives circuits for processing whisker-related information in mouse barrel cortex.

Excitatory spiny stellate neurons are prominently featured in the cortical circuits of sensory modalities that provide high salience and high acuity representations of the environment. These specialized neurons are considered developmentally linked to bottom-up inputs from the thalamus, however, the molecular mechanisms underlying their diversification and function are unknown. Here, we investigated this in mouse somatosensory cortex, where spiny stellate neurons and pyramidal neurons have distinct roles in processing whisker-evoked signals.

Microbiome modulates immunotherapy response in cutaneous squamous cell carcinoma.

The gut microbiome is increasingly recognized to alter cancer risk, progression and response to treatments such as immunotherapy, especially in cutaneous melanoma. However, whether the microbiome influences immune checkpoint inhibitor (ICI) immunotherapy response to non-melanoma skin cancer has not yet been defined. As squamous cell carcinomas (SCC) are in closest proximity to the skin microbiome, we hypothesized that the skin microbiome, which regulates cutaneous immunity, might affect SCC-associated anti-PD1 immunotherapy treatment response.

Caring for the caregiver in dementia.

Caregiver stress is higher for dementia caregiving than other types. By focusing on the family, FPs can help to ease the burden.

Integration and evaluation of chest X-ray artificial intelligence in clinical practice.

Purpose: To integrate and evaluate an artificial intelligence (AI) system that assists in checking endotracheal tube (ETT) placement on chest x-rays (CXRs) in clinical practice.

Approach: In clinical use over 17 months, 214 CXR images were ordered to check ETT placement with AI assistance by intensive care unit (ICU) physicians. The system was built on the SimpleMind Cognitive AI platform and integrated into a clinical workflow.

Ten-m4 plays a unique role in the establishment of binocular visual circuits.

The patterning of binocular vision requires distinct molecular pathways for inputs arising from each side of the nervous system. Recent studies have demonstrated important roles for members of the Ten-m/Odz/teneurin family in the development of ipsilateral retinal projections. Here, we further highlight the significance of this gene family in visual development by identifying a role for Ten-m4 during the formation of the ipsilateral projection in the mouse.

The "Syringe Hickey": An Alternative Skin Marking Method for Lumbar Puncture.

Background: Lumbar puncture is a procedure that is commonly performed in emergency departments. Despite their absence from procedure kits, emergency physicians often use skin markers to delineate landmarks for a lumbar puncture. We prefer to create a temporary indentation in the skin using the suction of a syringe.

Fumarate induces vesicular release of mtDNA to drive innate immunity.

Mutations in fumarate hydratase (FH) cause hereditary leiomyomatosis and renal cell carcinoma. Loss of FH in the kidney elicits several oncogenic signalling cascades through the accumulation of the oncometabolite fumarate. However, although the long-term consequences of FH loss have been described, the acute response has not so far been investigated.

Early Opportunities to Explore Occupational Identity Change: Qualitative Study of Return-To-Work Experiences After Stroke.

Background: Rates of return-to-work after stroke are low, yet work is known to positively impact people's wellbeing and overall health outcomes.

Objective: To understand return-to-work trajectories, barriers encountered, and resources that may be used to better support participants during early recovery and rehabilitation.

Participants: The experiences of 31 participants (aged 25-76 years) who had or had not returned to work after stroke were explored.

A Multisite Assessment of Inpatient Safety Event Rates During the Coronavirus Disease 2019 Pandemic.

To date, there has been a notable lack of peer-reviewed or publicly available data documenting rates of hospital quality outcomes and patient safety events during the coronavirus disease 2019 pandemic era. The dearth of evidence is perhaps related to the US health care system triaging resources toward patient care and away from reporting and research and also reflects that data used in publicly reported hospital quality rankings and ratings typically lag 2-5 years. At our institution, a learning health system assessment is underway to evaluate how patient safety was affected by the pandemic.

Dynamic partitioning of branched-chain amino acids-derived nitrogen supports renal cancer progression.

Metabolic reprogramming is critical for tumor initiation and progression. However, the exact impact of specific metabolic changes on cancer progression is poorly understood. Here, we integrate multimodal analyses of primary and metastatic clonally-related clear cell renal cancer cells (ccRCC) grown in physiological media to identify key stage-specific metabolic vulnerabilities.

Forming Micro-and Nano-Plastics from Agricultural Plastic Films for Employment in Fundamental Research Studies.

Microplastics (MPs) and nanoplastics (NPs) dispersed in agricultural ecosystems can pose a severe threat to biota in soil and nearby waterways. In addition, chemicals such as pesticides adsorbed by NPs can harm soil organisms and potentially enter the food chain. In this context, agriculturally utilized plastics such as plastic mulch films contribute significantly to plastic pollution in agricultural ecosystems.

Predictors of Invasiveness in Adenocarcinoma of Lung with Lepidic Growth Pattern.

Lung adenocarcinoma with lepidic growth pattern (LPA) is characterized by tumor cell proliferation along intact alveolar walls, and further classified as adenocarcinoma in situ (AIS), minimally invasive adenocarcinoma (MIA) and invasive lepidic predominant adenocarcinoma (iLPA). Accurate diagnosis of lepidic lesions is critical for appropriate prognostication and management as five-year survival in patients with iLPA is lower than in those with AIS and MIA. We aimed to evaluate the accuracy of CT-guided core needle lung biopsy classifying LPA lesions and identify clinical and radiologic predictors of invasive disease in biopsied lesions.

Tumor-Derived Lactic Acid Modulates Activation and Metabolic Status of Draining Lymph Node Stroma.

Communication between tumors and the stroma of tumor-draining lymph nodes (TDLN) exists before metastasis arises, altering the structure and function of the TDLN niche. Transcriptional profiling of fibroblastic reticular cells (FRC), the dominant stromal population of lymph nodes, has revealed that FRCs in TDLNs are reprogrammed. However, the tumor-derived factors driving the changes in FRCs remain to be identified.

Arterial Line Placement Pitfalls Can Be Demonstrated and Visualized With an Inexpensive, Wearable Trainer.

Background: Radial arterial line placement is commonly performed in various clinical settings, including the emergency department. However, learners are successful on the first attempt only half of the time. Simulation can provide learners with procedure practice opportunities outside of clinical practice to increase confidence and chances of success.

Comprehensive literature review on the radiographic findings, imaging modalities, and the role of radiology in the COVID-19 pandemic.

Since the outbreak of the coronavirus disease 2019 (COVID-19) pandemic, over 103214008 cases have been reported, with more than 2231158 deaths as of January 31, 2021. Although the gold standard for diagnosis of this disease remains the reverse-transcription polymerase chain reaction of nasopharyngeal and oropharyngeal swabs, its false-negative rates have ignited the use of medical imaging as an important adjunct or alternative. Medical imaging assists in identifying the pathogenesis, the degree of pulmonary damage, and the characteristic features in each imaging modality.

Development of a Programme Theory for Early Intervention Vocational Rehabilitation: A Realist Literature Review.

Purpose Little is currently known about how early intervention vocational rehabilitation (EIVR) works for people with newly acquired neurological conditions such as traumatic brain injury, acquired brain injury and spinal cord injury. This study aims, from a realist framework, to identify relevant literature and develop an initial programme theory to understand how EIVR might work for people experiencing acquired neurological disability. Realist reviews are ideally placed to address the identified knowledge gap as they assist in gaining a deeper understanding of how the intervention works, for whom it works best, and the contexts that promote the activation of desired outcomes.
