Precise Image-level Localization of Intracranial Hemorrhage on Head CT Scans with Deep Learning Models Trained on Study-level Labels.

Purpose To develop a highly generalizable weakly supervised model to automatically detect and localize image-level intracranial hemorrhage (ICH) by using study-level labels. Materials and Methods In this retrospective study, the proposed model was pretrained on the image-level Radiological Society of North America dataset and fine-tuned on a local dataset by using attention-based bidirectional long short-term memory networks. This local training dataset included 10 699 noncontrast head CT scans in 7469 patients, with ICH study-level labels extracted from radiology reports.

Communities Disproportionately Affected by Carbon Monoxide Exposure After Winter Storm Uri.

Extreme cold in February 2021 precipitated prolonged power failure in Texas. In Houston, many patients presented for carbon monoxide exposure from neighborhoods with lower per capita income, higher rates of limited English proficiency, and greater median Social Vulnerability Indices than Greater Houston. Weather-related disasters disproportionately affect socially vulnerable communities.

Upscaling net ecosystem CO exchanges in croplands: The application of integrating object-based image analysis and machine learning approaches.

Accurately estimating the net ecosystem exchange of CO (NEE) in cropland ecosystems is essential for understanding the impacts of agricultural practices and climate conditions. However, significant uncertainties persist in the estimation of regional cropland NEE due to landscape heterogeneity and variations in the efficacy of upscaling models. Here, we applied an integrated approach that combined object-based image analysis (OBIA) techniques with advanced machine learning (ML) approaches to upscale regional cropland NEE.

Predictors of salvage therapy for parasagittal meningiomas treated with primary surgery, radiosurgery, or surgery plus adjuvant radiotherapy.

Objective: Parasagittal meningiomas (PM) are treated with primary microsurgery, radiosurgery (SRS), or surgery with adjuvant radiation. We investigated predictors of tumor progression requiring salvage surgery or radiation treatment. We sought to determine whether primary treatment modality, or radiologic, histologic, and clinical variables were associated with tumor progression requiring salvage treatment.

Cranial Nerve Palsies in the Setting of Arachnoid Cysts: A Case Series and Literature Review.

Background: Arachnoid cysts (ACs) are benign lesions typically believed to not cause neurologic defects in the adult population and are most often found incidentally on imaging. We describe 2 patients with ACs potentially leading to isolated cranial nerve (CN) dysfunction.

Methods: We describe 2 patients, 1 with a fourth nerve palsy and the other with a sixth nerve palsy found to have ACs on MRI brain imaging in locations that potentially caused a compressive CN palsy.

State-Specific Medicaid/CHIP Eligibility Criteria and Their Impact on Health Care Access for Foreign-born Children Living in the United States.

Introduction: Foreign-born children are subject to discrepant state policies in determining eligibility for Medicaid/Children's Health Insurance Program (CHIP) coverage. The objective of this study was to determine the effect of these policies on health care access.

Methods: Data from the National Survey of Children's Health (NSCH) were used to assess associations between health care access outcomes and three categories of state health insurance eligibility: restrictive (only U.

Spanish-Speaking Caregivers' Perception of Emergency Physicians' Interpersonal and Communication Skills in a Pediatric Emergency Department.

Objectives: Medical communication is more than just the delivery of information; language differences between physicians and patients/caregivers create a challenge to providing effective care in the pediatric emergency department (ED). Overcoming this barrier is vital to providing high-quality care. We evaluated Spanish- versus English-speaking caregivers' perception of their pediatric ED physicians' interpersonal and communication skills.

Housing inadequacy in rural Saskatchewan First Nation communities.

Housing and house conditions on First Nation communities in Canada are important determinants of health for community members. Little is known about rural First Nation housing in the Canadian Prairies. The aim was to survey houses in two rural First Nation communities in Saskatchewan, Canada to understand housing conditions, prevalence of mold/mildew and dampness, and sources, locations and frequency of mold and dampness.

Monkeypox-Associated Central Nervous System Disease: A Case Series and Review.

Objective: Monkeypox virus (MPXV) disease has been declared a public health emergency by the World Health Organization, creating an urgent need for neurologists to be able to recognize, diagnosis, and treat MPXV-associated neurologic disease.

Methods: Three cases of MPXV-associated central nervous system (CNS) disease occurring during the 2022 outbreak, and their associated imaging findings are presented, with 2 cases previously published in a limited capacity in a public health bulletin.

Results: Three previously healthy immunocompetent gay men in their 30s developed a febrile illness followed by progressive neurologic symptoms with presence of a vesiculopustular rash.

Case Report: Anterior Spinal Cord Ischemia Following Embolization of Cerebellar Arteriovenous Malformation: An Illustrative Case and Review of Spinal Cord Vascular Anatomy.

Spinal cord ischemia (SCI) is a rare entity with high mortality and morbidity which can arise from causes such as atherosclerosis, aortic dissection or aneurysm, thromboembolic events or systemic hypotension, and is a potential complication of spinal surgery. Published literature contains very few reports of SCI as a complication of intracranial interventions, highlighting the uncommon nature of SCI in these circumstances. We report the occurrence of anterior SCI in a 69-year-old patient following successful embolization of a cerebellar arteriovenous malformation (AVM), marked by upper extremity weakness, lower extremity paraplegia, loss of bladder and bowel control, and hypercapnic respiratory failure requiring mechanical ventilation.

Pathologically stiff erythrocytes impede contraction of blood clots.

Background: Blood clot contraction, volume shrinkage of the clot, is driven by platelet contraction and accompanied by compaction of the erythrocytes and their gradual shape change from biconcave to polyhedral, with the resulting cells named polyhedrocytes.

Objectives: Here, we examined the role of erythrocyte rigidity on clot contraction and erythrocyte shape transformation.

Methods: We used an optical tracking methodology that allowed us to quantify changes in contracting clot size over time.

Children in Immigrant Families: Advocacy Within and Beyond the Pediatric Emergency Department.

In the United States, 1 in 4 children lives in an immigrant family. State and national policies have historically precluded equitable access to health care among children in immigrant families. More recently, increasingly restrictive policies, political rhetoric, and xenophobic stances have made immigrant families less able to access health care and less comfortable in attempting to do so, thus increasing the likelihood that patients will present to the emergency department.

Low socioeconomic status and eating in the absence of hunger in children aged 3-14.

A growing body of research indicates that one's early life experiences may play an important role in regulating patterns of energy intake in adulthood. In particular, adults who grew up under conditions characterized by low socioeconomic status (SES) tend to eat in the absence of hunger (EAH), a pattern that is not generally observed among higher-SES individuals. In the current study, we sought to examine (a) the environmental correlates of low SES that drive the association between low childhood SES and EAH and (b) whether the relationship between these variables is already manifest in children ages 3-14.

Childhood malnutrition within the indigenous Wayuú children of northern Colombia.

Malnutrition contributes to nearly half of all preventable deaths in children under the age of five. While the burden of disease is heaviest in Sub-Saharan Africa, South, and Southeast Asia, malnutrition in Latin America remains high, especially within indigenous communities. This study evaluates the prevalence of malnutrition and its relationship with access to healthcare resources within 172 indigenous Wayuú communities in La Guajira, Colombia.

An international stakeholder survey of the role of chiropractic qualifying examinations: .

Objective: Many countries require examinations as a gateway to chiropractic licensure; however, the relevance of these exams to the profession has not been explored. The purposes of this study were to analyze perceptions of international stakeholders about chiropractic qualifying examinations (CQEs), observe if their beliefs were in alignment with those that society expects of professions, and suggest how this information may be used when making future decisions about CQEs.

Methods: We designed an electronic survey that included open-ended questions related to CQEs.

NO Emissions From Two Agroecosystems: High Spatial Variability and Long Pulses Observed Using Static Chambers and the Flux-Gradient Technique.

With the addition of nitrogen (N), agricultural soils are the main anthropogenic source of NO, but high spatial and temporal variabilities make NO emissions difficult to characterize at the field scale. This study used flux-gradient measurements to continuously monitor NO emissions at two agricultural fields under different management regimes in the inland Pacific Northwest of Washington State, USA. Automated 16-chamber arrays were also deployed at each site; chamber monitoring results aided the interpretation of the flux gradient results.

Comparison of chiropractic student lexicon at two educational institutions: a cross-sectional survey.

Objective: To evaluate student perceptions of chiropractic cultural authority, role in healthcare and use of terms at two chiropractic institutions, the Canadian Memorial Chiropractic College (CMCC) and Parker University (Parker).

Methods: A unique survey was developed and administered electronically to Year 2-3 students (n=387) at CMCC and as a paper-based surveys to trimester 4-5 (comparison with Year 2) and 6-7 (comparison with Year 3) (n=277) students at Parker. Responses were anonymous.

A Traumatic Quinceañera: Acute Superior Mesenteric Artery Syndrome in an Adolescent Girl.

A 15-year-old girl presented with 3 days of progressive abdominal distention, pain, and bilious hematemesis. Her symptoms began after her quinceañera, during which she wore a tight corset. On examination, she was thin and had significant abdominal distention and pain.

Women Interact More Comfortably and Intimately With Gay Men-But Not Straight Men-After Learning Their Sexual Orientation.

Research suggests that the development of close, opposite-sex friendships is frequently impeded by men's often one-sided sexual attraction to women. But what if this element were removed? The current research tested the hypothesis that women engage in more comfortable and intimate interactions with a gay (but not a straight) man immediately after discovering his sexual orientation. In two studies, female participants engaged in imagined or actual initial interactions with either a straight man or a gay man.
