Helicosina, a new genus of Neotropical Limosininae (Diptera: Sphaeroceridae).

The new genus Helicosina is described to include three new Neotropical species characterized by swollen hind femora, cruciate interfrontal setae, strongly flattened notum and a distinctly narrow-elongate surstylus. At least one species is associated with furled Heliconia leaves. The following new species are described: H.

Human prolyl hydroxylase domain 2 reacts with O and 2-oxoglutarate to enable formation of inactive Fe(III).2OG.hypoxia-inducible-factor α complexes.

Hypoxia inducible transcription factors (HIFs) mediate the hypoxic response in metazoans. When sufficient O is present, Fe(II)/2-oxoglutarate (2OG)-dependent oxygenases (human PHD1-3) promote HIFα degradation via prolyl-hydroxylation. We report crystallographic, spectroscopic, and biochemical characterization of stable and inactive PHD2.

Using EMS data to explore community-level factors associated with firearm violence in North Carolina.

Background: Firearm violence is a significant public health issue. However, it is unclear if there is an association between the Social Vulnerability Index (SVI) and the intent of both fatal and nonfatal firearm injuries, and if these associations are modified by community race and ethnic composition. This study examines the association between community-level social vulnerability and firearm injury incidence in North Carolina (NC) using 2021-2022 emergency medical services (EMS) data.

Malpresentation and autism spectrum disorder in the study to explore early development.

Background: An infant's presentation at delivery may be an early indicator of developmental differences. Non-vertex presentation (malpresentation) complicates delivery and often leads to caesarean section, which has been associated with neurodevelopmental delays, including autism spectrum disorder (ASD). However, malpresentation could be an early sign of an existing developmental problem that is also an upstream factor from caesarean delivery.

Acute Kidney Injury in a Previously Healthy 56-Year-Old Male Following a Direct Visual Internal Urethrotomy of a Bulbar Stricture.

Acute kidney injury (AKI) is a frequent finding in acutely ill and hospitalized patients arising from various etiologies. Anuric AKI, a more pronounced form of AKI in which less than 100 cc of urine is produced per day, is most frequently encountered in hospitalized, septic, and post-surgical patients, often secondary to shock or bilateral urinary tract obstruction. The development of anuric AKI in previously healthy patients after outpatient urological procedures presents a unique challenge to physicians, as many outpatient procedures require the routine perioperative administration of multiple nephrotoxic medications.

Symptom Exacerbation and Adverse Events During a Randomized Trial of Early-Stage Rehabilitation After Sport-Related Concussion: Safety Outcomes From the Active Rehab Study.

Context: Authors of few studies have used randomized controlled trials (RCTs) to quantify clinical intervention safety of rehabilitation after sport-related concussion across sport levels.

Objective: Describe symptom exacerbation and adverse events (AEs) associated with two concussion rehabilitation interventions.

Design: Cluster RCT (NCT02988596).

Forty years of struggle in North Carolina: Workplace segregation and fatal occupational injury rates.

Objective: To assess workplace segregation in fatal occupational injury from 1992 to 2017 in North Carolina.

Methods: We calculated occupational fatal injury rates within categories of occupation, industry, race, age, and sex; and estimated expected numbers of fatalities among Black and Hispanic male workers had they experienced the rates of White male workers. We also estimated the contribution of workforce segregation to disparities by estimating the expected number of fatalities among Black and Hispanic male workers had they experienced the industry and occupation patterns of White male workers.

Urban segregation on multilayered transport networks: a random walk approach.

We present a novel method for analysing socio-spatial segregation in cities by considering constraints imposed by transportation networks. Using a multilayered network approach, we model the interaction probabilities of socio-economic groups with random walks and Lévy flights. This method allows for evaluation of new transport infrastructure's impact on segregation while quantifying each network's contribution to interaction opportunities.

Modeling Risk for Lower Extremity Musculoskeletal Injury in U.S. Military Academy Cadet Basic Training.

Introduction: Sport and tactical populations are often impacted by musculoskeletal injury. Many publications have highlighted that risk is correlated with multiple variables. There do not appear to be existing studies that have evaluated a predetermined combination of risk factors that provide a pragmatic model for application in tactical and/or sports settings.

Twenty-five year occupational homicide mortality trends in North Carolina: 1992-2017.

Introduction: Determining industry of decedents and victim-perpetrator relationships is crucial to inform and evaluate occupational homicide prevention strategies. In this study, we examine occupational homicide rates in North Carolina (NC) by victim characteristics, industry and victim-perpetrator relationship from 1992 to 2017.

Methods: Occupational homicides were identified from records of the NC Office of the Chief Medical Examiner system and the NC death certificates.

Space object identification and classification from hyperspectral material analysis.

This paper presents a data processing pipeline designed to extract information from the hyperspectral signature of unknown space objects. The methodology proposed in this paper determines the material composition of space objects from single pixel images. Two techniques are used for material identification and classification: one based on machine learning and the other based on a least square match with a library of known spectra.

The prFMNH-binding chaperone LpdD assists UbiD decarboxylase activation.

The UbiD enzyme family of prenylated flavin (prFMN)-dependent reversible decarboxylases is near ubiquitously present in microbes. For some UbiD family members, enzyme activation through prFMNH binding and subsequent oxidative maturation of the cofactor readily occurs, both in vivo in a heterologous host and through in vitro reconstitution. However, isolation of the active holo-enzyme has proven intractable for others, notably the canonical Escherichia coli UbiD.

Impact of alcohol driving-while-impaired license suspension duration on future alcohol-related license events and motor vehicle crash involvement in North Carolina, 2007 to 2016.

Background/purpose: License suspensions are a strategy to address alcohol-impaired driving behavior and recidivism following an alcohol driving while impaired (alcohol-DWI) conviction. Little is known about the specific impacts of conviction-related suspensions on safety outcomes and given recent fluctuations in alcohol-impaired driving behavior, crashes, and suspension trends, updated and focused assessments of this intervention are necessary. This study aimed to 1) examine the association between type of recent alcohol-DWI suspension and having a secondary alcohol-related license outcome and/or future crash event in North Carolina (NC) between 2007 and 2016; and 2) assess potential modification of these associations by race/ethnicity.

Forty-year trends in fatal occupational injuries in North Carolina.

Background: We describe progress in the control of deaths on-the-job due to fatal occupational injury in North Carolina over the period 1978-2017.

Methods: Forty years of information on fatal occupational injuries in North Carolina has been assembled from medical examiners' reports and death certificates, supplemented by newspaper and police reports. Cases were defined as unintentional fatal occupational injuries among adults.

Efficacy of a Novel Telehealth Application in Health Behavior Modification and Symptomology in Military Service Members at Risk for Post-traumatic Osteoarthritis.

Introduction: Mobile applications (apps) may be beneficial to promote self-management strategies to mitigate the risk of developing post-traumatic osteoarthritis in military members following a traumatic knee injury. This study investigated the efficacy of a mobile app in facilitating behavior modification to improve function and symptomology among military members.

Materials And Methods: This is a preliminary pre and post hoc analysis of a randomized control trial.

Fatal occupational injuries in North Carolina, 1992-2017.

Objectives: After declining for several decades, fatal occupational injury rates have stagnated in the USA since 2009. To revive advancements in workplace safety, interventions targeting at-risk worker groups must be implemented. Our study aims to identify these at-risk populations by evaluating disparities in unintentional occupational fatalities occurring in North Carolina (NC) from 1992 to 2017.

Medications for Opioid Use Disorder and Mortality and Hospitalization Among People With Opioid Use-related Infections.

Background: Severe skin and soft tissue infections related to injection drug use have increased in concordance with a shift to heroin and illicitly manufactured fentanyl. Opioid agonist therapy medications (methadone and buprenorphine) may improve long-term outcomes by reducing injection drug use. We aimed to examine the association of medication use with mortality among people with opioid use-related skin or soft tissue infections.

Virtual Reality for Preoperative Planning in Complex Surgical Oncology: A Single-Center Experience.

Introduction: Virtual reality models (VRM) are three-dimensional (3D) simulations of two-dimensional (2D) images, creating a more accurate mental representation of patient-specific anatomy.

Methods: Patients were retrospectively identified who underwent complex oncologic resections whose operations differed from preoperative plans between April 2018 and April 2019. Virtual reality modeling was performed based on preoperative 2D images to assess feasibility of use of this technology to create models.

Age, period and cohort-related trends in prescription opioid use in the USA, 1999-2018.

Background: To provide insight into the longitudinal dynamics of opioid use throughout the overdose crisis, this study estimated the separate influences of age, period and cohort on prescription opioid use during 1999-2018 in the USA.

Methods: Data from 10 cycles of the cross-sectional National Health and Nutrition Examination Survey were used to conduct an age-period-cohort analysis of the prevalence of prescription opioid use (n=63 500 across 1999-2018). Temporal trends were graphically visualised.
