BACKGROUND: Cranial and oral-maxillofacial injuries accounted for 33% of military visits to in-theater (Level III) military treatment facilities for battle injuries during Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF). Even after years of conflict, the size and scope of oral-maxillofacial injuries in military armed conflict is still not fully understood. This study reports U.S. Department of Defense (DoD) rates of oral-maxillofacial injuries that can be used for further surveillance and research...

INTRODUCTION: The most common psychological and cognitive sequelae associated with deployments to Afghanistan (Operation Enduring Freedom) and Iraq (Operation Iraqi Freedom) are mild traumatic brain injury (mTBI) and post-traumatic stress disorder (PTSD). High rates of PTSD are often observed among Veterans with a history of mTBI, and persistent postconcussive symptoms commonly endorsed after mTBI are known to be associated with PTSD. Therefore, this study examined whether PTSD mediates relations between postconcussive symptoms and 2 indices of medical disease burden: 1) the number of disease categories positive for a diagnosis, or system disease burden, and 2) total number of physical diagnoses, or cumulative disease burden...

OBJECTIVE: Veterans from recent military conflicts frequently report persisting symptoms associated with concussion well beyond the expected period of recovery following mild traumatic brain injury. This study examined differences in the reporting of symptoms associated with concussion between clinical and research contexts. METHODS: This naturalistic comparison included 91 Veterans from Operations Enduring Freedom (OEF), Iraqi Freedom (OIF) and New Dawn (OND). All participants were enrolled in a longitudinal study focused on traumatic brain injury and stress-related disorders and had also completed a VHA Comprehensive TBI Evaluation...

We describe a new methodology that sheds light on the fundamental electronic processes that occur at the subsurface regions of inorganic solid photocatalysts. Three distinct kinds of microscopic imaging are used that yield spatial, temporal, and energy-resolved information. We also carefully consider the effect of photon-induced near-field electron microscopy (PINEM), first reported by Zewail et al. in 2009. The value of this methodology is illustrated by studying afresh a popular and viable photocatalyst, hematite, α-Fe2O3 that exhibits most of the properties required in a practical application...

To better understand how sleep/wake dysregulation affects Alzheimer's disease (AD), we compared the cerebrospinal fluid (CSF) orexin and histamine/tele-methylhistamine (HA/t-MHA) levels of 82 patients (41 probable-AD-high level of evidence, 41 mild cognitive impairment MCI-due-to-AD), 24 other neurologic disorders (OND) and 24 controls. We determined the relationships between these biomarkers, the CSF AD biomarkers concentrations, and the clinical sleep profile. CSF orexin-A but not HA/t-MHA levels were higher in MCI and AD than OND and controls...

Many US veterans of Afghanistan and Iraq have multiple physical and psychiatric problems. A major focus of research has been on determining the effects of mild Traumatic Brain Injury (mTBI), but mTBI is rarely diagnosed in the absence of co-occurring conditions such as blast exposure, post-traumatic stress disorder (PTSD), depression, substance abuse, etc. These potentially interactive psychological and physical conditions produce complex patterns of cognitive, psychological, and physical symptoms that impede civilian reintegration and complicate efficient and effective treatment planning...

Many returning OIF/OEF/OND Veterans are seeking higher education in an effort to develop a meaningful career and financial stability. Evidence suggests that student service members/veterans (SSM/Vs) are experiencing less academic success than other students. The purpose of this review is to identify the unique challenges of SSM/Vs and evaluate current campus efforts to facilitate their retention and academic performance. With a focus on SSM/Vs attending colleges and universities, we obtained 57 peer-reviewed and 73 gray literature records published between 2001 and 2015...

There is a great deal of concern about opioid use in Veterans, particularly those that served in Afghanistan (OEF) and Iraq (OIF and OND). The current study provides a detailed pharmacoepidemiologic analysis of opioid use among OEF/OIF/OND Veterans from FY09 to FY12. Data from three data repositories from the Veterans Health Administration (VHA) were used to describe demographic, clinical, and medication characteristics associated with opioid use among OEF/OIF/OND Veterans and among those with TBI. Logistic regression models were used to identify risks associated with chronic opioid use in FY12...

Center-surround antagonism has been used as the canonical model to describe receptive fields of retinal ganglion cells (RGCs) for decades. We describe a newly identified RGC type in the mouse, called the ON delayed (OND) RGC, with receptive field properties that deviate from center-surround organization. Responding with an unusually long latency to light stimulation, OND RGCs respond earlier as the visual stimulus increases in size. Furthermore, OND RGCs are excited by light falling far beyond their dendrites...

We examined the use of the Personality Assessment Inventory (PAI) in a small sample of 47 U.S. military veterans of the conflicts in Iraq and Afghanistan. Approximately half of the sample met criteria for posttraumatic stress disorder (PTSD) based on the Clinician-Administered PTSD Scale. PAI profiles were compared between the PTSD and non-PTSD groups. The PTSD group had clinically significant scores (≥ 70 T) on the PAI for 5 clinical scales (anxiety, anxiety-related disorders, depression, paranoia, and schizophrenia) and 10 clinical subscales consistent with the typical symptom picture for PTSD...

OBJECTIVE: This study focuses on the first (S1) and sec-ond (S2) heart sound recognition based only on acoustic charac-teristics; the assumptions of the individual durations of S1 and S2 and time intervals of S1-S2 and S2-S1 are not involved in the recognition process. The main objective is to investigate whether reliable S1 and S2 recognition performance can still be attained under situations where the duration and interval information might not be accessible. METHODS: A deep neural network (DNN) method is proposed for recognizing S1 and S2 heart sounds...

OBJECTIVE: To assess the ownership and use of mosquito nets in 2014, in Mozambique. METHODS: This observational and cross-sectional study assessed, in February and March 2015, 69 districts (nine of 11 provinces of Mozambique) that have benefited from the mass distribution of mosquito nets. The Lot Quality Assurance Sampling methodology was used. Each locality was denominated supervision area. The Lot Quality Assurance Sampling opts for a minimum of 19 households (in this case, we decided for a minimum of 100 households per district) from each supervision area to assess an indicator (in this case, two indicators were assessed: ownership and use of mosquito nets)...

Background: A few decades ago, patients with Chagas disease were predominantly rural workers, with a low risk profile for obstructive coronary artery disease (CAD). As urbanization has increased, they became exposed to the same risk factors for CAD of uninfected individuals. Dobutamine stress echocardiography (DSE) has proven to be an important tool in CAD diagnosis. Despite being a potentially arrhythmogenic method, it is safe for coronary patients without Chagas disease. For Chagas disease patients, however, the indication of DSE in clinical practice is uncertain, because of the arrhythmogenic potential of that heart disease...

PTSD is characterized by both affective and cognitive dysfunction. Affectively, PTSD is associated with both heightened emotional reactivity and disengagement. Cognitively, perseverative thinking is a core feature of the disorder. In order to assess the interactive effects of affective and cognitive correlates of PTSD symptoms, 47 OEF/OIF/OND veterans completed an emotional faces matching task while EEG (i.e., late positive potential; LPP) was recorded, and separately completed the Wisconsin Card Sorting Test (WCST) to assess perseverative errors...

Laboratory-specific reference values for cerebrospinal fluid (CSF) Alzheimer disease (AD) biomarkers are necessary. Our objective was to apply well-known CSF biomarkers and redetermine their diagnostic cutoff values for AD in South Korea. CSF samples from matched control subjects (n=71), patients with AD dementia (ADD, n=76), and other neurological disorders with cognitive decline (OND, n=47) were obtained from 6 Korean dementia clinics according to a standardized protocol. CSF biomarker concentrations were measured using enzyme-linked immunosorbent assay...

An investigation was conducted for 20 different types of sludge in order to identify the key organic compounds in extracellular polymeric substances (EPS) that are important in assessing variations of sludge filterability. The different types of sludge varied in initial total solids (TS) content, organic composition and pre-treatment methods. For instance, some of the sludges were pre-treated by acid, ultrasonic, thermal, alkaline, or advanced oxidation technique. The Pearson's correlation results showed significant correlations between sludge filterability and zeta potential, pH, dissolved organic carbon, protein and polysaccharide in soluble EPS (SB EPS), loosely bound EPS (LB EPS) and tightly bound EPS (TB EPS)...
