Poor effort on cognitive testing in voluntary research predicts failure in US Army Ranger School: Implications for clinical trial design.

INTRODUCTION: Failure to provide effortful performance on cognitive testing is not uncommon for participants in clinical trials and can significantly impact sensitivity to treatment effect. Whether poor effort on cognitive testing might relate to other behaviors of interest is unknown. In the current investigation, we examined whether effort on baseline cognitive testing in a randomized controlled trial to enhance resiliency in US Army Officers predicted subsequent success in Ranger school. METHODS: Baseline data on six cognitive tests were obtained from 237 US Army Officers entering a military training program prior to attempting Ranger School. Participation was voluntary and the Army was not informed of test scores. "Poor effort" was defined by chance-level accuracy or extreme outlier scores. Logistic regression examined likelihood of Ranger success according to the number of tests with poor effort. RESULTS: Overall, 170 (72%) participants provided good effort on all tests. For these participants, 47% were successful in Ranger, versus 32% with poor effort on one test and 14% with poor effort on two tests. Logistic regression analysis found poor effort on baseline testing predicted reduced likelihood of Ranger success, ß =-.486, p = .005. DISCUSSION: A substantial number of participants exhibited poor effort on testing, and poor effort was predictive of failure in Ranger school. Findings highlight the importance of assessing effort in clinical trials involving cognitive outcomes and suggest application of cognitive effort testing in trials where other motivated behavior is targeted.

Indication Creep of Antenatal Late Preterm Steroids.

OBJECTIVE: While antenatal corticosteroids (ACS) administered in the late preterm period have been shown to reduce respiratory morbidity, this finding was demonstrated in a well-designed randomized controlled trial (the Antenatal Betamethasone for Women at Risk for Late Preterm Delivery [ALPS]) with strict inclusion/exclusion criteria that may differ from clinical practice. The aim of this study was to investigate whether there has been indication creep since use of late preterm ACS became standard of care. STUDY DESIGN: Retrospective cohort study of pregnant women who received late preterm ACS between 2016 and 2019 were identified and separated into epochs of 2016 to 2017 and 2018 to 2019 based on year of exposure. The primary outcome was rate of inappropriate ACS exposure, defined as nonadherence to the inclusion/exclusion criteria of the ALPS trial. Secondary outcomes were rates of nonoptimal ACS exposure (delivery >7 days from ACS or term delivery). Logistic regression was used to generate adjusted odds ratios (aORs) between epochs for the primary outcome adjusting for confounders. RESULTS: There were 660 women who received late preterm ACS during the study period with 229 (34.6 %) deemed inappropriate exposures. The most common reason for inappropriate treatment was preterm premature rupture of membrane (PPROM; 29.0%) with exclusionary cervical examination or contraction frequency. No difference was observed in inappropriate ACS exposure between epochs (aOR = 0.83, 95% confidence interval [CI]: 0.59-1.2). However, there was a reduction in nonoptimal exposure over time (aOR = 0.67, 95% CI: 0.47-0.97) . Women receiving inappropriate ACS were more likely to deliver at term if indicated for maternal/fetal status (50.0 vs. 19.5%, p < 0.001) and preterm labor (66.0 vs. 41.9%; p = 0.015). Further, inappropriate exposure in preterm labor had higher rates of exposure latency >7 days (62.3 vs. 39.1%, p = 0.006) with a longer latency to delivery (3 vs. 16 days; p < 0.001). CONCLUSION: Over one-third of women received late preterm ACS for an indication that could be classified as indication creep. Depending on indication, inappropriate administration is associated with higher rates of nonoptimal exposure. KEY POINTS: · There is potential for indication creep of ACS administration.. · One third of late preterm ACS exposures in our study were inappropriate.. · Utilizing clinical criteria can aid in identifying patients who best benefit from late preterm ACS..

Program to Avoid Cerebrovascular Events through Systematic Electronic Tracking and Tailoring of an Eminent Risk factor: Protocol of a RCT.

BACKGROUND: Geographical and racial disparities in stroke outcomes are especially prominent in the Southeastern United States, which represents a region more heavily burdened with stroke compared to the rest of the country. While stroke is eminently preventable, particularly via blood pressure control, fewer than one third of patients with a stroke have their blood pressure controlled ≥ 75% of the time, and low consistency of blood pressure control is linked to higher stroke risk. OBJECTIVE: To demonstrate that a mHealth technology-centered, integrated approach can effectively improve sustained blood pressure control among stroke patients (half of whom will be Black). DESIGN: The Program to Avoid Cerebrovascular Events through Systematic Electronic Tracking and Tailoring of an Eminent Risk-factor is a prospective randomized controlled trial, which will include a cohort of 200 patients with a stroke, encountered at two major safety net health care systems in South Carolina. The intervention comprises utilization of a Vaica electronic pill tray & blue-toothed UA-767Plus BT blood pressure device and a dedicated app installed on patients' smart phones for automatic relay of data to a central server. Providers will follow care protocols based on expert consensus practice guidelines to address optimal blood pressure management. STUDY OUTCOMES: Primary outcome is systolic blood pressure at 12-months, which is the major modifiable step to stroke event rate reduction. Secondary endpoints include control of other stroke risk factors, medication adherence, functional status, and quality of life. DISCUSSION: We anticipate that a successful intervention will serve as a scalable model of effective chronic blood pressure management after stroke, to bridge racial and geographic disparities in stroke outcomes in the United States.

Effect of Intensive vs Standard Blood Pressure Treatment Upon Erectile Function in Hypertensive Men: Findings From the Systolic Blood Pressure Intervention Trial.

INTRODUCTION: The effect of intensive blood pressure control upon erectile function in men with hypertension, but without diabetes, is largely unknown. AIM: To examine the effects of intensive systolic blood pressure (SBP) lowering on erectile function in a multiethnic clinical trial of men with hypertension. METHODS: We performed subgroup analyses from the Systolic Blood Pressure Intervention Trial ([SPRINT]; ClinicalTrials.gov: NCT120602, in a sample of 1255 men aged 50 years or older with hypertension and increased cardiovascular disease risk. Participants were randomly assigned to an intensive treatment group (SBP goal of <120 mmHg) or a standard treatment group (SBP goal of <140 mmHg). MAIN OUTCOME MEASURE: The main outcome measure was change in erectile function from baseline, using the 5-item International Index of Erectile Function (IIEF-5) total score, and erectile dysfunction ([ED]; defined as IIEF-5 score ≤21) after a median follow-up of 3 years. RESULTS: At baseline, roughly two-thirds (66.1%) of the sample had self-reported ED. At 48 months after randomization, we determined that the effects of more intensive blood pressure lowering were significantly moderated by race-ethnicity (p for interaction = 0.0016), prompting separate analyses stratified by race-ethnicity. In non-Hispanic whites, participants in the intensive treatment group reported slightly, but significantly better change in the IIEF-5 score than those in the standard treatment group (mean difference = 0.67; 95% CI = 0.03, 1.32; P = 0.041). In non-Hispanic blacks, participants in the intensive group reported slightly worse change in the IIEF-5 score than those in the standard group (mean difference = -1.17; 95% CI = -1.92, -0.41; P = 0.0025). However, in non-Hispanic whites and non-Hispanic blacks, further adjustment for the baseline IIEF-5 score resulted in nonsignificant differences (P > 0.05) according to the treatment group. In Hispanic/other participants, there were no significant differences in change in the IIEF-5 score between the two treatment groups (P = 0.40). In a subgroup of 280 participants who did not report ED at baseline, the incidence of ED did not differ in the two treatment groups (P = 0.53) and was without interaction by race-ethnicity. CLINICAL IMPLICATIONS: The effect of intensive treatment of blood pressure on erectile function was very small overall and likely not of great clinical magnitude. STRENGTH & LIMITATIONS: Although this study included a validated measure of erectile function, testosterone, other androgen, and estrogen levels were not assessed. CONCLUSION: In a sample of male patients at high risk for cardiovascular events but without diabetes, targeting a SBP of less than 120 mm Hg, as compared with less than 140 mm Hg, resulted in statistically significant effects on erectile function that differed in accordance with race-ethnicity, although the clinical importance of the differences may be of small magnitude.

Nutrients in the US Diet: Naturally Occurring or Enriched/Fortified Food and Beverage Sources, Plus Dietary Supplements: NHANES 2009-2012.

BACKGROUND: Nutrients are added to the diet through fortification/enrichment and dietary supplements (DSs). Meeting the US Dietary Reference Intakes (DRIs) varies by nutrient and population subsegments. OBJECTIVE: The aim of this study was to assess the relative role of naturally occurring, enriched/fortified, and DS sources of 15 micronutrients with reference to the DRIs. METHODS: We used the NHANES 2009-2012 (≥2 y old, n = 16,975) data, the ILSI North America Fortification database, and the National Cancer Institute usual intake method. RESULTS: Prevalence of nutrient intake from naturally occurring sources below the Estimated Average Requirement (EAR) varied from 5% for vitamin B-12 to 100% for vitamin D, with ≥40% of the population below the EAR for 8 of the 14 nutrients (ages ≥2 y). With enrichment/fortification, the percentage below the EAR decreased to the following for vitamins A (35%), C (34%), and B-6 (7%), folate (8%), thiamin (5%), riboflavin (3%), niacin (1%), and iron (2%). Nutrients from DSs further improved intakes related to the EAR for 12 nutrients (ages ≥2 y). For 9-18-y-olds, the percentages of nutrient intakes below the EAR were 14-50% higher than for 2-8-y-olds. The Tolerable Upper Intake Level (UL) was exceeded among children aged 2-8 y for folate (41.7%), niacin (10.1%), and zinc (39.9%), whereas among ages ≥2 y and 9-18 y no prevalence of intakes over the UL exceeded 10%. CONCLUSIONS: Fortification/enrichment constitutes a meaningful contribution to reducing the percentage of individuals with less than the EAR for their demographic. These data underscore the need to encourage better dietary patterns to improve the intake of nutrients at risk of low intake.

Blood Pressure, Sexual Activity, and Erectile Function in Hypertensive Men: Baseline Findings from the Systolic Blood Pressure Intervention Trial (SPRINT).

INTRODUCTION: Erectile function, an important aspect of quality of life, is gaining increased research and clinical attention in older men with hypertension. AIM: To assess the cross-sectional association between blood pressure measures (systolic blood pressure [SBP]; diastolic blood pressure [DBP]; and pulse pressure [PP]) and (i) sexual activity and (ii) erectile function in hypertensive men. METHODS: We performed analyses of 1,255 male participants in a larger randomized clinical trial of 9,361 men and women with hypertension aged ≥50 years. MAIN OUTCOME MEASURES: The main outcome measures were self-reported sexual activity (yes/no) and erectile function using the 5-item International Index of Erectile Function (IIEF-5). RESULTS: 857 participants (68.3%) reported being sexually active during the previous 4 weeks. The mean (SD) IIEF-5 score for sexually active participants was 18.0 (5.8), and 59.9% of the sample reported an IIEF-5 score <21, suggesting erectile dysfunction (ED). In adjusted logistic regression models, neither SBP (adjusted odds ratio = 0.998; P = .707) nor DBP (adjusted odds ratio = 1.001; P = .929) was significantly associated with sexual activity. In multivariable linear regression analyses in sexually active participants, lower SBP (ß = -0.04; P = .025) and higher DBP (ß = 0.05; P = .029) were associated with better erectile function. In additional multivariable analyses, lower PP pressure was associated with better erectile function (ß = -0.04; P = .02). CLINICAL IMPLICATIONS: Blood pressure is an important consideration in the assessment of erectile function in men with hypertension. STRENGTHS & LIMITATIONS: Assessments of blood pressure and clinical and psychosocial variables were performed using rigorous methods in this multi-ethnic and geographically diverse sample. However, these cross-sectional analyses did not include assessment of androgen or testosterone levels. CONCLUSIONS: Erectile dysfunction was highly prevalent in this sample of men with hypertension, and SBP, DBP, and PP were associated with erectile function in this sample.

Examining the association between musculoskeletal injuries and carpal tunnel syndrome in manual laborers.

INTRODUCTION: The association between musculoskeletal injuries and carpal tunnel syndrome (CTS) has not been investigated in a large, population-based study. METHODS: Latino manual laborers were recruited as part of a study of work-related health conditions. Each had a clinical examination, completed a hand diagram, and had nerve conduction studies. RESULTS: A total of 512 individuals completed all testing. An association was found between rotator cuff syndrome and CTS, with an adjusted odds ratio of 2.25 (P = 0.01) for the right arm, 2.08 (P = 0.03) for the left arm, and 1.84 (P = 0.03) for all individuals. Associations between epicondylitis and CTS did not reach statistical significance. CONCLUSIONS: Individuals with rotator cuff syndrome have a higher prevalence of CTS. Further investigations will be needed to examine for causation and to determine if 1 condition typically occurs first and leads to the other. Muscle Nerve 54: 31-35, 2016.

Blood Pressure, Sexual Activity, and Dysfunction in Women With Hypertension: Baseline Findings From the Systolic Blood Pressure Intervention Trial (SPRINT).

INTRODUCTION: Sexual function, an important component of quality of life, is gaining increased research and clinical attention in older women with hypertension. AIM: To assess the association between systolic blood pressure (SBP) and other variables, and sexual activity and sexual dysfunction in hypertensive women. METHODS: Baseline analysis of 635 women participants of a larger randomized clinical trial of 9361 men and women. MAIN OUTCOME MEASURES: Self-reported sexual activity (yes/no), and sexual function using the Female Sexual Function Inventory (FSFI). RESULTS: 452 participants (71.2%) reported having no sexual activity during the previous 4 weeks. The mean (SD) FSFI score for sexually active participants was 25.3 (6.0), and 52.6% of the sample reported a FSFI score ≤26.55 designating sexual dysfunction. In logistic regression models, SBP was not significantly associated with sexual activity (AOR = 1.002; P > .05). Older age (AOR = 0.95, P < .05), and lower education (AOR for < high school vs college degree = 0.29, P < .05) were associated with lower odds of being sexually active, as was living alone versus living with others (AOR = 0.56, P < .05). Higher weekly alcohol consumption was associated with increased odds of being sexually active (AOR = 1.39; P < .05). In logistic regression models among sexually active participants, SBP was not associated with sexual dysfunction (AOR = 1.01; P > .05). Higher depressive symptoms from the Patient Health Questionnaire-9 (PHQ-9) was associated with higher odds of sexual dysfunction (AOR = 1.24, P < .05), as was increased number of physical comorbidities (AOR = 1.25, P < .05). Diuretic use was associated with lower odds of being sexually active in participants with chronic kidney disease (AOR = 0.33, P < .05). CONCLUSION: Younger age, higher education, living with others, and higher weekly alcohol consumption were significantly associated with higher odds of being sexually active in a sample of middle-aged and older women with hypertension. Increased depressive symptoms and increased physical comorbidities were significantly associated with increased odds of sexual dysfunction. SBP was not significantly associated with sexual activity or sexual dysfunction.

A multi-site randomized clinical trial to reduce suicidal ideation in suicidal adult outpatients with Major Depressive Disorder: Development of a methodology to enhance safety.

BACKGROUND/AIMS: Suicide is a major public health concern, yet there are very few randomized clinical trials that have been conducted to reduce suicidal ideation in patients at risk of suicide. We describe the rationale and refinements of such a trial that is designed to assess the effect of a hypnotic medication on suicidal ideation in adult outpatients currently experiencing suicidal ideation. METHODS: "Reducing Suicidal Ideation Through Insomnia Treatment" is a multi-site randomized clinical trial that includes three recruiting sites and one data management site. This 4-year study is in its second year of recruitment. The purpose of the study is to compare hypnotic medication versus placebo as an add-on treatment to a selective serotonin reuptake inhibitor as a means of reducing suicidal ideation in depressed adult outpatients with insomnia and suicidal ideation. The safety features of the study follow the 2001 National Institutes of Health guidelines for studies that include patients at risk of suicide. RESULTS: In total, 584 potential participants have undergone telephone screening; 67% of these failed the phone screen, most often due to an absence of expressed suicidal ideation (26% of the telephone screen fails). A total of 115 people appeared for a face-to-face baseline assessment, and 40 of these had completed a taper off of their ineffective psychotropic medications before the baseline assessments. In all, 64% of those who completed baseline assessments failed to proceed to randomization, most commonly because of no clinically significant suicidal ideation (51% of those excluded at baseline). One participant was offered and accepted voluntary psychiatric hospitalization in lieu of study participation. Thus far, 40 participants have been randomized into the study and 88.7% of scheduled visits have been attended, with 93.8% adherence to the selective serotonin reuptake inhibitor and 91.6% adherence to the randomized hypnotic versus placebo. None of the randomized participants have required hospitalization or had a suicide attempt. CONCLUSION: By carefully considering the inclusion and exclusion criteria and other safety features, the safe conduct of randomized clinical trials in suicidal adult patients is possible, including the inclusion of participants who have undergone a prescribed tapering off of psychotropic medications prior to baseline assessment.

Muscle intrusion as a potential cause of carpal tunnel syndrome.

INTRODUCTION: The aim of this study was to determine whether there is an association between flexor digitorum and lumbrical muscle intrusion into the carpal tunnel and carpal tunnel syndrome (CTS). METHODS: Five hundred thirteen manual laborers (1026 wrists) were evaluated with ultrasound to determine whether those with CTS had more muscle intrusion into the carpal tunnel than those without CTS. One hundred ninety of the participants without CTS at baseline (363 wrists) were followed over 1 year to determine whether muscle intrusion at baseline predicted the development of CTS. RESULTS: Participants with CTS had more muscle within the carpal tunnel with the wrist in the neutral (P=0.026) and flexed (P=0.018) positions than those without CTS. Baseline muscle intrusion did not predict development of CTS at 1 year. CONCLUSIONS: Muscle intrusion into the carpal tunnel is associated with CTS, but muscle intrusion alone does not predict the development of CTS over the course of a year.

Self-reported skin symptoms and skin-related quality of life among Latino immigrant poultry processing and other manual workers.

BACKGROUND: Manual labor employment occurs in environments with exposures likely to impact skin-related quality of life (SRQOL). OBJECTIVES: The objectives of this paper are to (1) document the dimensions of SRQOL, (2) examine its association with skin symptoms, and (3) identify the predictors of SRQOL in Latino manual workers. METHODS: A population-based survey of 733 Latino manual workers obtained Dermatology Life Quality Index (DLQI) and skin symptoms in the prior year. RESULTS: Two-thirds of workers were employed in production. Skin symptoms in prior year were reported by 23%. Impaired SRQOL was reported by 23%. In multivariate analyses, reduced SRQOL was associated with age, occupation, childhood indigenous language use, and experience of skin symptoms in the prior year. CONCLUSIONS: Despite overall high SRQOL exposures in some immigrant occupational groups produce reduce SRQOL. This rural, immigrant population faces significant obstacles to obtaining dermatological care; efforts are needed to improve their SRQOL.

One-year incidence of carpal tunnel syndrome in Latino poultry processing workers and other Latino manual workers.

OBJECTIVE: To determine the incidence of carpal tunnel syndrome (CTS) over 1 year in Latino poultry processing workers. METHODS: Symptoms and nerve conduction studies were used to identify Latino poultry processing workers (106 wrists) and Latinos in other manual labor occupations (257 wrists) that did not have CTS at baseline, and these individuals were then evaluated in the same manner 1 year later. RESULTS: Based on wrists, the 1-year incidence of CTS was higher in poultry processing workers than non-poultry manual workers (19.8% vs. 11.7%, P = 0.022). Poultry workers had a higher odds (1.89; P = 0.089) of developing CTS over 1 year compared to non-poultry manual workers. DISCUSSION: Latino poultry processing workers have an incidence of CTS that is possibly higher than Latinos in other manual labor positions. Latino poultry workers' high absolute and relative risk of CTS likely results from the repetitive and strenuous nature of poultry processing work.

Comorbidity of tinea pedis and onychomycosis and evaluation of risk factors in Latino immigrant poultry processing and other manual laborers.

OBJECTIVES: Latino immigrant workers experience elevated rates of skin disease that result from their working and living conditions. Working in manual occupations exposes workers to a variety of challenges, including occlusive shoes, vigorous physical activity, and wet conditions. These challenges predispose workers to fungal infection. The objectives of this article are to examine the comorbidity of tinea pedis and onychomycosis and to identify possible risk factors among Latino immigrant poultry and nonpoultry workers in western North Carolina. METHODS: Data were obtained from a cross-sectional study conducted between June 2009 and November 2010 in rural western North Carolina among 518 manual Latino immigrant workers to assess their occupational injuries. Participants completed a face-to-face interview and a dermatologic examination. RESULTS: Nearly one-third of the participants (32%) were diagnosed as having onychomycosis and more than one-third (37.8%) were diagnosed as having tinea pedis. There was a greater prevalence of tinea pedis in men than women (71.3% vs 28.7%, respectively). Of the 518 participants, 121 (23.5%) had both conditions. Participants who reported the use of occlusive shoes as "always" or "most of the time" had a higher prevalence of comorbid onychomycosis and tinea pedis than the rest of the group. CONCLUSIONS: Comorbidity of tinea pedis and onychomycosis is common among immigrant Latino men and women who perform manual labor. Further studies confirming the presence and type of dermatophyte should be conducted.

Recurrent neonatal acute kidney injury: incidence, predictors, and outcomes in the neonatal intensive care unit.

OBJECTIVE: Determine recurrent neonatal acute kidney injury (rAKI) incidence, risk factors, and associated outcomes. STUDY DESIGN: Single-center retrospective cohort of neonates admitted to the NICU 1/1/20-6/30/21. Comparisons were made between those with no AKI, single AKI episode (sAKI), and rAKI. Multivariable linear and logistic regression models were used to assess associations between rAKI and length of mechanical ventilation (LMV), length of hospitalization stay (LOS), mortality, and hypertension (HTN) at discharge. RESULTS: The incidence of AKI in the cohort of 869 infants was 19%: 705 (81%) no AKI, 100 (12%) sAKI, 64 (7%) rAKI. Both sAKI and rAKI were independently associated with longer LMV and LOS. sAKI was independently associated with almost 4x higher odds of mortality than rAKI. CONCLUSION: In this single center cohort of neonates, sAKI independently predicts mortality, however rAKI is independently associated with increased LMV and LOS suggesting rAKI is clinically important and warrants further study.

Post-natal steroid exposure in very low birthweight neonates and associations with acute kidney injury.

OBJECTIVE: The relationship between adrenal insufficiency (AI), post-natal steroids (PNS) and neonatal acute kidney injury (AKI) remains understudied. We investigated associations between PNS and AKI in very low birthweight (VLBW) neonates, hypothesizing PNS is associated with reduced AKI. STUDY DESIGN: We conducted a single-center retrospective review of VLBW infants comparing those with and without PNS exposure. Associations between PNS exposure and AKI were evaluated using generalized linear mixed-modeling adjusted for confounders. RESULT: Of 567 neonates, 97 (17.1%) were exposed to PNS and 130 (22.9%) experienced AKI. Infants with PNS had lower gestational age, birthweight, Apgar scores, and experienced more AI versus those without PNS (all p < 0.05). PNS was associated with AKI (aRR 1.72, 95% CI 1.09-2.72) though hydrocortisone alone was not. CONCLUSION: PNS exposure, but not hydrocortisone alone, is associated with increased AKI in VLBW neonates. Further analysis is needed to investigate the role of AI and AKI.

Narcissism Is Not Associated With Success in U.S. Army Soldier Training.

INTRODUCTION: Narcissism has been studied for its role in leadership using various versions of the Narcissistic Personality Inventory (NPI). Narcissism is described as having a "dark and negative" side as well as a "positive or bright" side. The bright side of narcissism, in particular, has been studied for its role in leadership. In studies among military personnel in Finland and Hungary, the NPI has been associated with positive leadership traits. We assessed if measures of narcissistic personality were predictive of entrance to and graduation from the Army Ranger Course among United States (U.S.) Army personnel. MATERIALS AND METHODS: We included the NPI as one of the measures in the Ranger Resilience and Improved Performance on Phospholipid-bound Omega-3's (RRIPP-3) study. RRIPP-3 was a double-blind, placebo-controlled dietary supplement intervention trial at Fort Benning, GA, that enrolled 555 officers when they entered the U.S. Army Infantry Basic Officer Leadership Course (IBOLC) with the intention to complete the U.S. Ranger School. RRIPP-3 volunteer participants consumed eight dietary supplements daily containing 2.3 g of omega-3 (krill oil) or macadamia nut oil (control) over a 20-week period. Blood spot samples were collected to monitor intake compliance. Cognitive functioning, resilience, and mood were assessed at approximately 14 and 16 weeks. Dietary intake was also assessed. The 40-item, forced-choice NPI was included to assess if three factors of narcissism: Leadership/Authority, Grandiose/Exhibitionism, and Entitlement/Exploitativeness measures of narcissistic personality were associated with entrance to and graduation from the Army Ranger Course. RESULTS: Of the 555 soldiers enrolled in RRIPP-3, there were no statistically significant differences in the total NPI scores comparing U.S. Army IBOLC officers who enrolled (n = 225) versus did not enroll (n = 330, p = .649) or graduated (n = 95; versus did not graduate [n = 460, p = .451]) from the Ranger Course. None of the three-factor NPI subscales differed statistically comparing either enrollment in (p = .442, .510, and .589, respectively) or graduation from the Ranger Course (p = .814, .508, and .813, respectively). CONCLUSIONS: Although narcissism has been positively associated with military trainee success in other countries, we did not find an association between narcissism and trainee success among U.S. Army trainees, and accordingly the level of narcissism did not predict trainee success or failure.

Latency of late preterm steroid administration to delivery and risk of neonatal hypoglycemia.

BACKGROUND: Late preterm antenatal corticosteroid administration has been associated with an increased risk of neonatal hypoglycemia. The mechanism is thought to be secondary to transient fetal hyperinsulinemia, which may be more likely if delivery occurs during peak antenatal corticosteroid levels. OBJECTIVE: This study aimed to investigate whether there is a latency interval between antenatal corticosteroid administration and delivery that places neonates at the greatest risk of hypoglycemia. STUDY DESIGN: This was a retrospective matched cohort study of pregnant women who received antenatal corticosteroid vs unexposed women between 34 0/7 and 36 6/7 weeks of gestation from 2016 to 2019. Unexposed women were those who did not receive antenatal corticosteroid matched according to gestational age at delivery, diabetes mellitus status, and maternal body mass index from 2010 to 2015. Latency periods from initial steroid administration to delivery were defined in grouped intervals until ≥72 hours. The primary outcome was neonatal hypoglycemia, defined as a neonatal glucose level of <40 mg/dL within 24 hours of life. Poisson regression was used to generate an adjusted relative risk of hypoglycemia for each latency period adjusting for confounders. RESULTS: A total of 812 women were included in the analysis (406 exposed and 406 unexposed). Women who received antenatal corticosteroids were more likely to be nulliparous (P=.009); moreover, the women were well matched on pregnancy complications and baseline demographics. Neonatal hypoglycemia was more frequently identified in women receiving antenatal corticosteroids than in women not receiving antenatal corticosteroids (42% vs 26%; P<.001). Severe hypoglycemia, defined as a glucose level of <20 mg/dL, was significantly more common in patients receiving antenatal corticosteroids than in patients not receiving antenatal corticosteroids (8.4% vs 2.7%; P<.001). Latency time intervals of 12 to 71 hours from antenatal corticosteroid administration were significantly associated with neonatal hypoglycemia in exposed women compared with unexposed women after adjustment; within this time frame, the highest risk was 24 to 47 hours after antenatal corticosteroid administration (adjusted relative risk, 2.09; 95% confidence interval, 1.29-3.38). CONCLUSION: In the late preterm period, the risk of neonatal hypoglycemia is the greatest in the latency period of 12 to 71 hours between steroid administration and delivery. Neonates exposed to antenatal corticosteroids were more likely to experience severe hypoglycemia within 24 hours of life than unexposed neonates.

Impact of Fatty Acid Supplementation on Cognitive Performance among United States (US) Military Officers: The Ranger Resilience and Improved Performance on Phospholipid-Bound Omega-3's (RRIPP-3) Study.

Studies have assessed omega-3 fatty acids and cognitive decline among older adults and cognitive development among children, although less is known about cognitive or neurological effects among young adults. We examined whether omega-3 supplementation from krill oil could improve cognition and resilience among young military officers compared to a control. This double-blind, placebo-controlled trial enrolled 555 officers (mean age 23.4 ± 2.8, 98.6% male) entering the United States (US) Army Infantry Basic Officer Leaders Course (IBOLC) with the intention to complete the US Ranger Course. Volunteer participants consumed eight dietary supplements daily of krill oil containing 2.3 g omega-3 or control (macadamia nut oil) over an approximate 20-week period. Cognitive functioning, resilience, and mood were assessed during a well-rested period at approximately 14 weeks and after a battlefield simulation at 16 weeks. Blood spot samples were collected to monitor compliance and dietary intake was assessed. All hypotheses were tested using both 'Intention to Treat' (ITT) and 'As Per Protocol' (APP) approaches. Of the 555 randomized individuals, 245 (44.1%) completed the study. No statistically significant group-by-time interactions indicating treatment effect were found on any outcomes. Poor compliance was indicated by lower than expected omega-3 elevations in the treatment group, and may have contributed to a failure to detect a response.

Very low birth weight infants receive full enteral nutrition within 2 postnatal weeks.

OBJECTIVE: Identify whether an enteral nutrition goal of reaching full feeds by 7 postnatal days for infants 1-1.5 kg and by 14 postnatal days for infants <1 kg was feasible and its associated outcomes. STUDY DESIGN: Very low birth weight infant cohort admitted in the first postnatal day and categorized as either Epoch 1 or Epoch 2, 12 months before and after implementation of a revised feeding protocol were compared. RESULT: In Epoch 2, 83% infants born 1-1.5 kg and 77% infants born <1 kg reached full feeds by 7 and 14 days compared to 26% and 25%, respectively in Epoch 1 (p < 0.0001). Central line and parental nutrition days were significantly lower in Epoch 2 compared to Epoch 1 with sustained and potentially improved infant growth. CONCLUSION: An evidence-based advancement feeding protocol was associated with achieving full feeds within the first 2 postnatal weeks for very low birth weight infants.

Modeling Possible Outcomes of Updated Daily Values on Nutrient Intakes of the United States Adult Population.

The United States (US) Food and Drug Administration has updated the Daily Values (DVs) for the Nutrition Facts Label on packaged foods. We used the National Health and Nutrition Examination Survey 2009-2012 data with the International Life Sciences Institute, North America Fortification Database, which identifies intrinsic, mandatory enriched, and fortified sources of nutrients in foods and beverages, to model the new DVs' potential impact on adult (≥19 years of age) intake. We assumed that manufacturers will adjust voluntary fortification to maintain percent DV claims. We assessed the percent of the US population whose usual intake (UI) was < the Estimated Average Requirement (EAR), and ≥ the Upper Limit (UL) based on the current DVs, and modeled estimated UI and %
