Clinical applications of exosomes in cosmetic dermatology.

Introduction: Exosomes are extracellular vesicles that transport bioactive substances during normal and abnormal cellular physiological processes. The unique properties of exosomes can be exploited for use as biomarkers and targeted drug delivery vehicles, and are, for this reason, gaining increasing attention in the field of dermatology. This review aims to synthesise the existing evidence supporting exosomes in regenerative and cosmetic dermatology.

Evaluating Renal Disease in Pediatric-Onset Antineutrophil Cytoplasmic Antibody-Associated Vasculitis: Disease Course, Outcomes, and Predictors of Outcome.

Objective: We aimed to study the disease course, outcomes, and predictors of outcome in pediatric-onset antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) affecting the kidneys.

Methods: Patients eligible for this study had a diagnosis of granulomatosis with polyangiitis (GPA), microscopic polyangiitis, or ANCA-positive pauci-immune glomerulonephritis, were 18 years or younger at diagnosis, had renal disease defined by biopsy or dialysis dependence, and had clinical data at diagnosis and at either 12 or 24 months. Ambispective data from A Registry for Children with Vasculitis/Pediatric Vasculitis Initiative Registry was used.

Inferring disease progression stages in single-cell transcriptomics using a weakly supervised deep learning approach.

Application of single-cell/nucleus genomic sequencing to patient-derived tissues offers potential solutions to delineate disease mechanisms in humans. However, individual cells in patient-derived tissues are in different pathological stages, and hence, such cellular variability impedes subsequent differential gene expression analyses. To overcome such a heterogeneity issue, we present a novel deep learning approach, scIDST, that infers disease progression levels of individual cells with weak supervision framework.

Innovative strategies and implementation science approaches for health delivery among migrants in humanitarian settings: A scoping review.

Introduction: Over 100 million displaced people rely on health services in humanitarian contexts, defined as unstable or transitory settings created in response to complex emergencies. While services are often described, there is a dearth of evidence on best practices for successful implementation to guide efforts to optimize health delivery. Implementation science is a promising but underutilized tool to address this gap.

Monitoring youth-appealing advertising on social media for the e-cigarette brand Lost Mary.

Lost Mary is a popular e-cigarette brand among youth in the United States. This study aimed to analyze Lost Mary's branded social media activity and assess whether marketing efforts may have contributed to its youth appeal. We conducted a content analysis of 53 Lost Mary posts published on social media platforms from 2022 to 2023.

Assessments of working group effectiveness in the planning of the New Jersey Kids Study: An applied mixed-methods study on the science of team science.

Introduction: The New Jersey Kids Study (NJKS) is a transdisciplinary statewide initiative to understand influences on child health, development, and disease. We conducted a mixed-methods study of project planning teams to investigate team effectiveness and relationships between team dynamics and quality of deliverables.

Methods: Ten theme-based working groups (WGs) (e.

The Hidden Burden: Unveiling the Cervical Cancer Burden Among Recent Afghan Women Immigrants in the United States.

Cervical cancer is a significant global health issue, ranking as the second most prevalent cancer among women of reproductive age. While prevention strategies like HPV vaccination and screening have made it highly preventable, these benefits are mostly seen in high-HDI nations. In contrast, LMICs lag behind, with Afghanistan facing a growing crisis due to war, poverty, and lack of awareness.

Sheep Head Cadaveric Model for the Transmeatal Extensions of the Retrosigmoid Approach.

The transmeatal extension of the retrosigmoid approach is an important procedure used in the treatment of various pathologies affecting the posterior fossa, petroclival region, and jugular foramen. Mastering this technique requires a high level of manual skill, particularly in temporal bone drilling. The objective of this study was to describe an easily accessible and cost-effective model of the transmeatal extension of the retrosigmoid approach using cadaveric sheep heads.

Endoscopic Local Excision (ELE) with Knife-Assisted Resection (KAR) Techniques Followed by Adjuvant Radiotherapy and/or Chemotherapy for Invasive (T1bsm2,3/T2) Early Rectal Cancer: A Multicenter Retrospective Cohort.

Resected rectal polyps with deep invasion into the submucosa (pT1b-sm2,3) or the muscle layer (pT2) are currently confronted with surgery due to non-curative resection. We evaluated the efficacy, safety, and locoregional control of adjuvant radiotherapy (RT) and/or chemotherapy (CT) following endoscopic KAR (knife-assisted resection) in patients with invasive early rectal cancers who are unwilling or unsuitable for additional surgical resection. Fifty-one patients with early rectal cancers, pT1b or pT2, underwent post-resection adjuvant RT and/or CT in 15 centers worldwide.

Time delay and evidence profiles forming clinical recommendations of US surgical society guidelines.

Introduction: Surgical society guidelines facilitate implementation of up-to-date, evidence-based care, but concerns regarding the contemporality and quality of evidence can hinder adherence. We aimed to evaluate the time gap between evidence publication and their inclusion within clinical guidelines-the publication-to-guideline delay-and characterize the quality of evidence within contemporary surgical society guidelines.

Study Design: This cross-sectional study analyzed guidelines published by U.

The RNA chaperone protein ProQ is a pleiotropic regulator in enteropathogenic Escherichia coli.

Enteropathogenic Escherichia coli (EPEC) is a gastrointestinal pathogen that affects individuals of all age groups, with infections ranging from subclinical colonization to acute or persistent diarrhea. The bacterium's ability to cause diarrhea depends on the locus of enterocyte effacement (LEE) pathogenicity island. Although regulation of the LEE has been systematically characterized, until the last decade, studies mainly focused on its transcriptional control.

Placental abruption and perinatal mortality in twins: novel insight into management at preterm versus term gestations.

Twins suffer a disproportionately higher burden of adverse perinatal outcomes than singletons. However, the degree to which preterm delivery shapes the relationship between abruption and perinatal mortality in twins is unknown. Through causal mediation decomposition, we examine how preterm delivery mediates the effect of abruption on perinatal mortality among twins using the US-matched multiple birth data (1995-2000).

Imaging the large-scale and cellular response to focal traumatic brain injury in mouse neocortex.

Traumatic brain injury (TBI) affects neural function at the local injury site and also at distant, connected brain areas. However, the real-time neural dynamics in response to injury and subsequent effects on sensory processing and behaviour are not fully resolved, especially across a range of spatial scales. We used in vivo calcium imaging in awake, head-restrained male and female mice to measure large-scale and cellular resolution neuronal activation, respectively, in response to a mild/moderate TBI induced by focal controlled cortical impact (CCI) injury of the motor cortex (M1).

Nailfold microscopy in adult-onset dermatomyositis in association with myositis antibodies.

Dermatomyositis (DM) is an immune mediated inflammatory disease classically associated with muscular and cutaneous involvement. Existing studies have suggested characteristic nailfold findings may be observed in DM, indicating a potential role for nailfold microscopic examination in the diagnosis of DM. To that end, we performed a systematic review of literature pertaining to nailfold microscopic, capillaroscopic, and dermoscopic findings observed in patients with DM, with a secondary review of the association of nailfold microscopic findings with myositis-specific antibody (MSA) and myositis-associated antibody (MAA) status.

Essential Reads in Rhinology: A Bibliometric Analysis.

Aims: Rhinology is a progressive subspecialty within otolaryngology. Bibliometric analysis is a powerful method to survey the landscape of literature on a specific topic and identify publication trends. We aimed to analyze the 50 most impactful English-language rhinology manuscripts of all time to create a targeted reading list for otolaryngologists.
