Wealth is health: High economic status in Cameroon correlates with protective gear use in traffic injuries and improved clinical outcomes.

Introduction: Africa is the least motorized populated continent, yet it experiences the highest traffic fatality rate. Despite laws mandating helmet and seatbelt use, data on protective gear use among Cameroonian road traffic injury (RTI) patients remains sparse.

Methods: We extracted Cameroon Trauma Registry data prospectively collected from 10 hospitals during July 2022 to December 2023.

Diversity in the US Academic Microsurgery Pathway.

Although the representation of women and ethnic minority students in the US medical schools has recently increased, discrepancies in representation among plastic surgery residents and faculty continue. The state of sex and ethnic diversity in academic microsurgery remains minimally investigated. We aimed to evaluate the sex, race, and ethnicity demographics among academic microsurgeons and identify underrepresentation along the leadership pathway.

Prehospital factors associated with mortality among road traffic injury patients: analysis of Cameroon trauma registry data.

Background: Cameroon is amongst the worst affected countries by road traffic injuries with an estimated 1443 disability-adjusted life years per 100,000 population. There have been very limited reports on the crucial prehospital response to road traffic injuries in Cameroon. This study aimed to identify prehospital factors associated with RTI mortality in Cameroon.

Prevalence and Factors Associated With Alcohol-Related Road Traffic Injuries in Cameroon.

Introduction: While the negative effects of drunk driving, including road traffic injuries (RTIs) have been well documented in high-income countries, little has been reported in African countries like Cameroon. This study aimed to measure the prevalence of alcohol-related RTIs (ARRTIs), its associated factors, and its association with injury severity.

Methods: The Cameroon Trauma Registry prospectively collects trauma data from 10 hospitals in Cameroon.

Who seeks care after intimate partner violence in Cameroon? sociodemographic differences between a hospital and population sample of women.

Introduction: Little is known regarding health care seeking behaviors of women in sub-Saharan Africa, specifically Cameroon, who experience violence. The proportion of women who experienced violence enrolled in the Cameroon Trauma Registry (CTR) is lower than expected.

Methods: We concatenated the databases from the October 2017-December 2020 CTR and 2018 Cameroon Demographic and Health Survey (DHS) into a singular database for cross-sectional study.

Functional stress responses in Glaucophyta: Evidence of ethylene and abscisic acid functions in Cyanophora paradoxa.

Glaucophytes, an enigmatic group of freshwater algae, occupy a pivotal position within the Archaeplastida, providing insights into the early evolutionary history of plastids and their host cells. These algae possess unique plastids, known as cyanelles that retain certain ancestral features, enabling a better understanding of the plastid transition from cyanobacteria. In this study, we investigated the role of ethylene, a potent hormone used by land plants to coordinate stress responses, in the glaucophyte alga Cyanophora paradoxa.

From targets to solutions: Implementing a trauma quality improvement bundle in Cameroon.

Background: Global surgery research efforts have been criticized for failure to transition from problem identification to intervention implementation. We developed a context-appropriate trauma quality improvement (TQI) bundle to ameliorate care gaps at a regional referral hospital in Cameroon. We determined associations between bundle implementation and improvement in trauma resuscitation practices.

Crystalloid resuscitation is associated with decreased treatment delays and improved systolic blood pressures in a blood-constrained setting.

Objectives: We analyzed resuscitation practices in Cameroonian patients with trauma as a first step toward developing a context-appropriate resuscitation protocol. We hypothesized that more patients would receive crystalloid-based (CB) resuscitation with a faster time to administration than blood product (BL) resuscitation.

Methods: We included patients enrolled between 2017 and 2019 in the Cameroon Trauma Registry (CTR).

Mobile health follow-up screening to risk stratify patients in need of further care in a low resource setting: Results from a prospective multisite implementation study.

Background: Routine in-person follow-up for injured patients after hospital discharge is unfeasible in low- and middle-income countries where trauma morbidity and mortality are the highest. Mobile technology screening may facilitate early detection of complications and timely treatment. In this prospective, multisite implementation study, we cross-validate the performance of a cellphone screening tool developed to risk stratify trauma patients in need of further care after discharge in Cameroon.

From Genes to Ambiguity: A Case Study Exploring the Enigmatic Connection Between Chromosome 13q Deletion Syndrome and Ambiguous Genitalia.

During development, the deletion of DNA from chromosome 13's short arm (q) causes a chromosomal abnormality known as chromosome 13q deletion syndrome. Chromosome 13 terminal deletions are rare and may cause various congenital disabilities, and only a few cases have been reported in the literature. The extent of chromosome 13q deletion syndrome changes lacks consistent clinical features, with no recorded cases of genital ambiguity until now.

Non-ionizing radiation modeling to predict ambient irradiance in work areas at an indoor cannabis farm.

Agricultural workers frequently experience potentially hazardous exposure to non-ionizing radiation from both solar and artificial sources, and measurement of this exposure can be expensive and impractical for large populations. This project develops and evaluates a vegetative radiative transfer model (VRTM) to predict irradiance in a grow room of an indoor cannabis farm. The model uses morphological characteristics of the crop, manufacturer provided lamp emissions data, and dimensional measurements of the grow room and cannabis hedgerows to predict irradiance.

The CBS test: Development, evaluation & cross-validation of a community-based injury severity scoring system in Cameroon.

Injury-related deaths overwhelmingly occur in low and middle-income countries (LMICs). Community-based injury surveillance is essential to accurately capture trauma epidemiology in LMICs, where one-third of injured individuals never present to formal care. However, community-based studies are constrained by the lack of a validated surrogate injury severity metric.

Blue orchard bee (Hymenoptera: Megachilidae) origin and orchard growing region affect female retention at artificial nest sites in cherry orchards.

The blue orchard bee, Osmia lignaria Say (Hymenoptera: Megachilidae), is a solitary, cavity-nesting species used for pollinating spring blooming crops. Commercial stocks are sourced from a few locations in the western United States but are sold across the country. However, the existence of local adaptations of these bees is unknown, such as the propensity to nest in nearby provided materials or to disperse broadly beyond release sites.

Pleural and Pericardial Effusion With COVID-19 and Systemic Lupus Erythematosus and Its Recurrence: A Case Study.

As a chronic autoimmune disease, systemic lupus erythematosus (SLE) primarily affects young women and does not discriminate against any particular organs. In December 2019, coronavirus disease 2019 (COVID-19) spread worldwide, with many speculations of cardiac involvement in the pathogenesis of infection. Moreover, in cases where cardiac symptoms were described, they consisted solely of chest pain or a general deterioration in health if the patient presented with pleural effusion or pericardial effusion.

Back to the basics: Clinical assessment yields robust mortality prediction and increased feasibility in low resource settings.

Introduction: Mortality prediction aids clinical decision-making and is necessary for trauma quality improvement initiatives. Conventional injury severity scores are often not feasible in low-resource settings. We hypothesize that clinician assessment will be more feasible and have comparable discrimination of mortality compared to conventional scores in low and middle-income countries (LMICs).

Wearable Spectroradiometer for Dosimetry.

Available wearable dosimeters suffer from spectral mismatch during the measurement of broadband UV and visible radiation in environments that receive radiation from multiple sources emitting differing spectra. We observed this type of multi-spectra environment in all five Washington State cannabis farms visited during a field study investigating worker exposure to ultraviolet radiation in 2018. Spectroradiometers do not suffer from spectral mismatch in these environments, however, an extensive literature review conducted at the time of writing did not identify any spectroradiometers that were directly deployable as wearable dosimetry devices.

Predictors of Dairy Worker Pre-Test and Post-Test Performance on a Dairy Safety Knowledge Test: Impact of Education Level and Native Language.

Background: Efficacy-driven assessments of linguistically appropriate occupational health and safety training (OHS) for dairy workers remain uncommon. This study analyzes predictors of performance on a dairy safety knowledge test using pre-and-post knowledge assessments. The safety training course was delivered by iPad™ to Idahoan dairy workers, managers, and owners.

Multi-informant validity evidence for the SSIS SEL Brief Scales across six European countries.

The SSIS SEL Brief Scales (SSIS SEL) are multi-informant (teacher, parent, and student) measures that were developed to efficiently assess the SEL competencies of school-age youth in the United States. Recently, the SSIS SEL was translated into multiple languages for use in a multi-site study across six European countries (Croatia, Greece, Italy, Latvia, Portugal, and Romania). The purpose of the current study was to examine concurrent and predictive evidence for the SEL Composite scores from the translated versions of the SSIS SEL Scales.
