A Narrative Review of Congenital Syphilis in the United States: Innovative Perspectives on a Complex Public Health and Medical Disease.

Over the past two decades, congenital syphilis cases have risen 11-fold in the United States. While disparities across geography, race, and ethnicity exist, lack of timely screening or treatment is identified in 88% of cases nationally. Congenital syphilis is a public health and medical problem rooted in systematic and societal structural determinants of health and healthcare limitations.

Purpose in life and stress: An individual-participant meta-analysis of 16 samples.

Background: Purpose in life is a psychological resource that has been associated with better regulation of stress. The present research reports a coordinated analysis of the association between purpose in life and subjective stress and evaluates potential sociodemographic and mental health moderators of this association.

Methods: With individual participant data from 16 samples (total =108,391), linear regression examined the association between purpose in life and general subjective feelings of stress, controlling for sociodemographic characteristics.

In 'IX: people and places-diverse populations and locations of care', authors address the following themes: 'LGBTQIA+health in family medicine', 'A family medicine approach to substance use disorders', 'Shameless medicine for people experiencing homelessness', '''Difficult" encounters-finding the person behind the patient', 'Attending to patients with medically unexplained symptoms', 'Making house calls and home visits', 'Family physicians in the procedure room', 'Robust rural family medicine' and 'Full-spectrum family medicine'. May readers appreciate the breadth of family medicine in these essays.

A thyroidea ima artery variation providing collateral circulation to the mediastinum.

The thyroidea ima artery (TIA) is a highly variable arterial deviation of the blood supply to the thyroid gland with critical implications for surgical neck procedures such as tracheostomy. Though relatively common in the population at large (~ 4%), most TIA variations are related to the origin of the artery and whether it emerges from the common sites of the brachiocephalic trunk, aortic arch, and right common carotid artery, or another more unique vessel-as opposed to its dispersion pattern. TIA variants generally supply the thyroid gland, occasionally co-occurring with absent thyroid arteries.

Purpose in life, stress mindset, and perceived stress: Test of a mediational model.

Purpose in life is associated with less perceived stress and more positive worldviews. This study examined whether people with more purpose adopt a mindset that views stress as beneficial rather than harmful and whether this mindset is one mechanism between purpose and less stress. We used a short-term longitudinal study (=2,147) to test stress mindset as a mediator between purpose in life measured prior to the pandemic and stress measured early in the pandemic.

Circular mitochondrial-encoded mRNAs are a distinct subpopulation of mitochondrial mRNA in Trypanosoma brucei.

Since the first identification of circular RNA (circRNA) in viral-like systems, reports of circRNAs and their functions in various organisms, cell types, and organelles have greatly expanded. Here, we report the first evidence, to our knowledge, of circular mRNA in the mitochondrion of the eukaryotic parasite, Trypanosoma brucei. While using a circular RT-PCR technique developed to sequence mRNA tails of mitochondrial transcripts, we found that some mRNAs are circularized without an in vitro circularization step normally required to produce PCR products.

A year in review: brain barriers and brain fluids research in 2022.

This aim of this editorial is to highlight progress made in brain barrier and brain fluid research in 2022. It covers studies on the blood-brain, blood-retina and blood-CSF barriers (choroid plexus and meninges), signaling within the neurovascular unit and elements of the brain fluid systems. It further discusses how brain barriers and brain fluid systems are impacted in CNS diseases, their role in disease progression and progress being made in treating such diseases.

Oral anticoagulation use in non-valvular atrial fibrillation patients in rural setting.

Background: The 2019 ACC/AHA/HRS guidelines established direct oral anticoagulants (DOACs) as first line therapy over warfarin for non-valvular atrial fibrillation (AF).

Methods: Ambulatory clinic patients with non-valvular AF or atrial flutter seen between 10/1/2019-7/12/2020 included. High-risk AF defined as males CHADS-VASc score ≥2 and females ≥3.

Advances in brain barriers and brain fluids research in 2021: great progress in a time of adversity.

This editorial highlights advances in brain barrier and brain fluid research in 2021. It covers research on components of the blood-brain barrier, neurovascular unit and brain fluid systems; how brain barriers and brain fluid systems are impacted by neurological disorders and their role in disease progression; and advances in strategies for treating such disorders.

A Middle Pleistocene Denisovan molar from the Annamite Chain of northern Laos.

The Pleistocene presence of the genus Homo in continental Southeast Asia is primarily evidenced by a sparse stone tool record and rare human remains. Here we report a Middle Pleistocene hominin specimen from Laos, with the discovery of a molar from the Tam Ngu Hao 2 (Cobra Cave) limestone cave in the Annamite Mountains. The age of the fossil-bearing breccia ranges between 164-131 kyr, based on the Bayesian modelling of luminescence dating of the sedimentary matrix from which it was recovered, U-series dating of an overlying flowstone, and U-series-ESR dating of associated faunal teeth.

Geographically diverse canid sampling provides novel insights into pre-industrial microbiomes.

Canine microbiome studies are often limited in the geographic and temporal scope of samples studied. This results in a paucity of data on the canine microbiome around the world, especially in contexts where dogs may not be pets or human associated. Here, we present the shotgun sequences of fecal microbiomes of pet dogs from South Africa, shelter and stray dogs from India, and stray village dogs in Laos.

Molnupiravir; molecular and functional descriptors of mitochondrial safety.

Molnupiravir is an orally active nucleoside analog antiviral drug that recently was approved by the U.S. FDA for emergency treatment of adult patients infected with the SARS-CoV-2 (COVID-19) virus and at risk for severe progression.

Weaving pathways: talking with our Elders.

While there exists a relative paucity of completed healthcare directives nationally in the USA, even fewer exist within minority populations. This report describes one model for bringing advance care planning and discussions to American Indian and Alaska Native (AIAN) communities. In 2018, Honoring Choices of Minnesota approached the Center of American Indian and Minority Health (CAIMH), housed in the University of Minnesota Medical School, to collaborate on a project to increase healthcare directives in AIAN communities.

Cost determinants among adults hospitalized with respiratory syncytial virus in the United States, 2017-2019.

Background: Respiratory syncytial virus (RSV) infections are common in adults, but data describing the cost of RSV-associated hospitalization are lacking due to inconsistency in diagnostic coding and incomplete case ascertainment. We evaluated costs of RSV-associated hospitalization in adult patients with laboratory-confirmed, community-onset RSV.

Methods: We included adults ≥ 18 years of age admitted to three hospital systems in New York during two RSV seasons who were RSV-positive by polymerase chain reaction (PCR) and had more than or equal to two acute respiratory infection symptoms or exacerbation of underlying cardiopulmonary disease.

Exploring the Scope and Dimensions of Vaccine Hesitancy and Resistance to Enhance COVID-19 Vaccination in Black Communities.

Background: The long history of distrust that characterizes the relationship between the Black/African-American population and the US Medical community makes COVID-19 vaccine hesitancy of great concern. A needs assessment of the Black/African-American community assessed willingness and explored the perceptions of community members regarding COVID-19 vaccination.

Methods: The study used a mixed-methods approach.

Canadian Indigenous Cognitive Assessment (CICA): Inter-rater reliability and criterion validity in Anishinaabe communities on Manitoulin Island, Canada.

Introduction: Despite increasing dementia rates, few culturally informed cognitive assessment tools exist for Indigenous populations. The Canadian Indigenous Cognitive Assessment (CICA) was adapted with First Nations on Manitoulin Island, Canada, and provides a brief, multi-domain cognitive assessment in English and Anishinaabemowin.

Methods: Using community-based participatory research (CBPR) methods, we assessed the CICA for inter-rater and test-retest reliability in 15 individuals.

Predictive power of SARS-CoV-2 wastewater surveillance for diverse populations across a large geographical range.

The COVID-19 pandemic has exacerbated the disparities in healthcare delivery in the US. Many communities had, and continue to have, limited access to COVID-19 testing, making it difficult to track the spread and impact of COVID-19 in early days of the outbreak. To address this issue we monitored severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA at the population-level using municipal wastewater influent from 19 cities across the state of Minnesota during the COVID-19 outbreak in Summer 2020.

Probabilistic models of biological enzymatic polymerization.

In this study, hierarchies of probabilistic models are evaluated for their ability to characterize the untemplated addition of adenine and uracil to the 3' ends of mitochondrial mRNAs of the human pathogen Trypanosoma brucei, and for their generative abilities to reproduce populations of these untemplated adenine/uridine "tails". We determined the most ideal Hidden Markov Models (HMMs) for this biological system. While our HMMs were not able to generatively reproduce the length distribution of the tails, they fared better in reproducing nucleotide composition aspects of the tail populations.
