  The goal of this systematic review and meta-analysis is to understand cardiovascular health outcomes following wildfire and determine if fuel type clarifies variation in the association. The systematic review included English, peer-reviewed, primary data analysis studies that explored wildfire exposures with associated cardiovascular morbidity or mortality health outcomes published up to October 17, 2023 and identified through five databases (PROSPERO Protocol #CRD42024589994). We extracted article details, fire exposure metrics, cardiovascular health outcome metrics, study design, measures of association (risk ratio [RRs], incidence rate ratios [IRRs] and 95 % confidence intervals [CIs]), covariates, confounding factors, and stratified analyses from each article. Risk of bias was assessed using the Cochrane tool. Random effects meta-analyses, stratified by natural or structure/peat fuel types were conducted. Pooled estimates for all cardiovascular disease (pRR:1.04, 95 % CI: 1.01, 1.07), dysrhythmia (pRR:1.05, 95 % CI: 1.01, 1.09), and hypertensive disease (pRR:1.04, 95 % CI: 1.01, 1.07) were significantly associated with fire exposure. There were significant between group differences between wildfires with structure/peat sources compared to natural sources for all cardiovascular ED visits (RR structure/peat: 1.08, 95 % CI: 1.03, 1.12; RR natural: 1.03, 95 % CI: 1.00, 1.05) and dysrhythmia ED visits (RR structure/peat: 1.10, 95 % CI: 1.04, 1.09; RR natural: 1.02, 95 % CI: 0.98, 1.06). When exploring pooled estimates of risk for cardiovascular health, we find higher estimates and narrower CIs for structure/peat sources compared to natural wildfires with largely null estimates and wider CIs. Future detailed and consistent information about wildfire fuel types will help to inform better wildfire response.

Helicobacter pylori Diagnostic Testing Accuracy in a High-Prevalence Native American Population of Northern Arizona. Microorganisms, 13(Issue 8). doi:10.3390/microorganisms13081920

  Helicobacter pylori (H. pylori) is a common gastric pathogen and a leading cause of non-cardia gastric cancers. Known determinants can affect the diagnostic accuracy of invasive clinical methods for H. pylori diagnosis. The objective of this study was to determine the diagnostic accuracy of the CLOtest, a rapid urease test, and the histopathologic examination compared with polymerase chain reaction (PCR) in esophagogastroduodenoscopy patients from a population with high prevalence and other risk factors that may influence diagnostic accuracy. From 2018 to 2022, patients were recruited from a medical care center serving the southwestern Navajo Nation. Summary statistics were calculated using PCR as the comparator to the CLOtest and histopathologic examination. Among the 466 study participants, 27.1% (95% CI 22.9, 31.7%) tested positive for H. pylori using PCR to detect pathogen DNA. Sensitivity was lowest for the CLOtest (57.0%; 95% CI 45.8, 67.6) and highest for the combination the CLOtest and histopathology (72.2%; 95% CI 62.8, 80.4). Patient history of infection or possible GI bleeding influenced sensitivity by over 5%. In high H. pylori prevalence areas, emphasis should be placed on ensuring adequate treatment of suspected positive infections as false-positive results were rare. Including a more sensitive test might reduce the number of individuals falsely classified as H. pylori negative.

  Mental health concerns in adults are increasingly common, especially among parents and caregivers, and our current conventional treatments often fail to take effective treatment for the whole family into consideration. Adults' emotional health can be inextricably linked to the mental health of their children. If a child's therapy is successful in helping the child while also engaging, educating, and empowering caregivers, this both has an indirect impact on caregivers' health, and the potential to directly and indirectly benefit the affected adults by nurturing a future healthy relationship. Theraplay is an integrative, intense, play-based, therapist-directed, and parent/caregiver-engaged therapy that helps forge healthy attachments between children and their adults. Theraplay has demonstrated marked benefits for multiple ailments in children, as reviewed below, and, by intentionally integrating their adult in the therapy, has potential to positively impact mental health of the caregivers engaged in their child's treatment. The effects of forging or restoring a child's ability to form healthy relationships could provide long-term, continuing benefits for the child and, potentially, their caregivers.

  The insulin receptor possesses tyrosine kinase activity which is thought to mediate the biological effects of insulin upon target cells. pp120 is a liver-specific glycoprotein of apparent molecular size of 120 kDa that is phosphorylated on tyrosine residues by the receptors for insulin, insulin-like growth factor-I, and epidermal growth factor. Previously, we demonstrated that pp120 is identical to a liver-specific ecto-ATPase. In the present study, we have cloned the rat gene encoding pp120/ecto-ATPase. The gene is contained within approximately 15 kilobases of genomic DNA, and consists of nine exons interrupted by eight introns. Using the reverse transcriptase/polymerase chain reaction, we isolated cDNA clones complementary to rat liver mRNA encoding pp120/ecto-ATPase. Sequence analysis indicated the presence of two populations of cDNA's that differ by the presence or absence of a 53-base pair (bp) fragment encoding the juxta-membrane region of the cytoplasmic domain. By cloning the corresponding region of the ecto-ATPase gene, we demonstrated that the 53-bp represents exon 7 of the gene. This 53-bp exon undergoes alternative splicing, thereby giving rise to two mRNA variants. Deletion of this 53-bp cassette exon introduces a frameshift, and results in a premature chain termination codon that truncates the cytoplasmic domain. The truncated cytoplasmic domain contains 10 rather than 71 amino acid residues. Because the short isoform of ecto-ATPase lacks the putative sites for tyrosine- and serine-specific phosphorylation, this alternative splicing may have a major effect upon the physiological function of the enzyme.
