Background: Neck pain is a common condition that is often difficult to diagnose. Previous literature has investigated diagnostic accuracy of examination measures, but the strength and clinical applicability are limited. This overview of systematic reviews aimed to investigate clinical features for diagnosing neck pain and its associated disorders.

Article Synopsis
  • Most people in the US are exposed to PFAS, which can lead to health risks, especially in low-income communities near PFAS-polluting facilities.
  • In a study in Southern California, researchers connected PFAS levels in plasma samples with data on water contamination, food access, and pollution sources to analyze exposure impacts.
  • Results showed that higher PFAS levels in drinking water and the presence of Superfund sites increased PFAS concentrations in participants' blood, highlighting the need to address PFAS exposure in disadvantaged areas.

Background: There is no guideline regarding whether patients treated with intravenous corticosteroids for acute severe ulcerative colitis (ASUC) should be monitored in the hospital after transitioning to oral steroids. Our study aimed to: (1) compare rates of oral steroid transition failure and 30-day readmission between ASUC hospitalizations with extended inpatient monitoring compared to accelerated inpatient monitoring, and (2) identify predictors of oral steroid transition failure.

Methods: A retrospective cohort study of ulcerative colitis (UC) related admissions at UCSF from 2014 to 2022 was conducted comparing rates of steroid transition failures in extended inpatient monitoring (≥ 24 h on oral steroids prior to discharge) to accelerated inpatient monitoring (< 24 h on oral steroids).

  • A cross-sectional study explored the relationship between air pollution, specifically fine particulate matter, and neurocognitive performance in 9- to 10-year-old children in the US, using data from the Adolescent Brain Cognitive Development Study.
  • The researchers analyzed 15 chemical components of air pollution by evaluating children's residential addresses and applied various modeling techniques to assess cognitive outcomes, including general ability and executive function.
  • The findings revealed that exposure to certain pollution mixtures, particularly ammonium nitrates and traffic-related pollutants, was linked to poorer cognitive performance, while some unexpected positive associations were also noted.

Background: Little is known about how childhood exposure to traffic-related air pollution (TRAP) and stress interact to affect adults' cardiometabolic health. We examined this interaction and assessed the impact of over 10 years of childhood TRAP exposure on cardiometabolic health.

Methods: From 2018 to 2023, 313 young adults from the Southern California Children's Health Study were enrolled in a follow-up assessment.

Purpose: Patients with Crohn's disease (CD) and subsequent ocular manifestations may have worse outcomes when compared to matched patients with CD without ocular disease.

Methods: In this retrospective cohort study, an aggregated electronic health records research network, TriNetX (Cambridge, MA, USA), was used to identify patients diagnosed with CD stratified by the presence or absence of ocular involvement with at least 1 year of follow-up. Propensity score matching (PSM) was performed to control for baseline demographics and medical comorbidities.

In this study, associations between prenatal exposure to fine particulate matter (PM2.5) from 9 sources and development of autism spectrum disorder (ASD) were assessed in a population-based retrospective pregnancy cohort in southern California. The cohort included 318,750 mother-child singleton pairs.

  • rVSVΔG-ZEBOV-GP is a vaccine that helps protect people from the Ebola virus and is the first one to be officially approved for this purpose.
  • This study wanted to see how well a booster shot given 18 months after the first vaccine dose helped keep the immune response strong for a longer time.
  • Healthy adults who might be at risk of exposure to Ebola participated in the trial, and the results measured their antibody levels 36 months after the first vaccination to compare those who got the booster with those who did not.

  • Dry needling (DN) is a popular treatment for musculoskeletal pain, but there are concerns about potential serious adverse events in sensitive areas like the spine.
  • This study aimed to explore whether a specific DN technique could allow a needle to penetrate the ligamentum flavum and potentially the spinal canal at the thoracolumbar junction.
  • The results showed that using ultrasound guidance, a dry needle could successfully enter the spinal canal, indicating the technique's feasibility and emphasizing the importance of ultrasound in safely conducting dry needling in critical areas.

While fine particulate matter (PM) has been associated with autism spectrum disorder (ASD), few studies focused on ultrafine particles (PM). Given that fine and ultrafine particles can be highly correlated due to shared emission sources, challenges remain to distinguish their health effects. In a retrospective cohort of 318,371 mother-child pairs (4549 ASD cases before age 5) in Southern California, pregnancy average PM and PM were estimated using a California-based chemical transport model and assigned to residential addresses.

  • Opioid use in hospitalized patients with inflammatory bowel disease doesn't help with pain and might keep them in the hospital longer.
  • A study tracked patients with acute severe ulcerative colitis and found that those using a lot of opioids had delays in getting other important treatments.
  • Patients who used high amounts of opioids were more likely to leave the hospital with opioids, while overall, the use of opioids didn't change their hospital stay length or costs.

JCO The APHINITY trial (ClinicalTrials.gov identifier: NCT01358877) previously demonstrated that pertuzumab added to adjuvant trastuzumab and chemotherapy improved invasive disease-free survival (iDFS) for patients with early human epidermal growth factor receptor 2-positive (HER2+) breast cancer (BC). Here, we report the preplanned third interim analysis of overall survival (OS) and a descriptive updated iDFS analysis with 8.

Objective: To test whether the association between flavor at first vape and continued use is mediated through subjective experience at first vape.

Study Design: In a 2020 cross-sectional survey, 955 young adult ever-vapers recalled their first flavor vaped, subjective experiences at first use, current vaping behavior, nicotine dependence, and quit attempts. A latent class model grouped first-use subjective experiences into classes.

  • Echogenicity of the carotid arterial wall, indicated by IM-GSM values, is a new marker for subclinical atherosclerosis, where lower values suggest more lipid buildup; our study tracked these values from childhood into adulthood.
  • In our research involving 240 participants, IM-GSM decreased significantly from an average of 108.2 in childhood to 75.6 in adulthood, with various factors such as weight, blood pressure, and parental education influencing these levels.
  • The study concludes that a decrease in IM-GSM with age highlights the importance of maintaining a healthy weight and blood pressure in children to possibly prevent future atherosclerosis.

Background: We tested whether snus marketing with modified risk tobacco product (MRTP) claims: (a) promotes accurate knowledge about snus's health effects in young adults and (b) encourages use intentions in only those who use combustible tobacco without attracting other young adult populations.

Methods: A randomised between-subjects experiment was embedded in a 2020 web survey of participants from Los Angeles (aged 19-23 years). Participants viewed mass-marketed snus advertising materials with (n=1212) vs without (n=1225) US Food and Drug Administration-authorised MRTP claims.

  • This study explores the link between adolescent cannabis use and the ongoing use of nicotine products, aiming to inform prevention strategies.
  • Researchers analyzed data from 14-17-year-olds in Southern California, focusing on different types of cannabis use (smoking, vaping, edibles) and their effects on nicotine use persistence over a 6-month period.
  • Findings suggest that adolescents who use cannabis are significantly more likely to continue using nicotine products, especially e-cigarettes, while cannabis use did not appear to influence the persistence of combustible tobacco use.
