AbstractAtmospheric rivers (ARs) are responsible for up to 90% of major flood events along the U.S. West Coast. The timescale of subseasonal forecasting (two weeks to one month) is a critical lead time for proactive mitigation of flood disasters. The NOAA/Climate Testbed Subseasonal Experiment (SubX) is a research-to-operations project with almost immediate availability of forecasts. It has produced a reforecast database that facilitates evaluation of flood forecasts at these subseasonal lead times. Here, we examine the SubX driven forecast skill of AR-related flooding out to 4-week lead using the Distributed Hydrology Soil Vegetation Model (DHSVM), with particular attention to the role of antecedent soil moisture (ASM), which modulates the relationship between meteorological and hydrological forecast skill. We study three watersheds along a transect of the U.S. West Coast: the Chehalis River basin in Washington, the Russian River basin in Northern California, and the Santa Margarita River basin in Southern California. We find that the SubX driven flood forecast skill drops quickly after week 1, during which there is relatively high deterministic forecast skill. We find some probabilistic forecast skill relative to climatology as well as ensemble streamflow prediction (ESP) in week 2, but minimal skill in weeks 3-4, especially for annual maximum floods, notwithstanding some probabilistic skill for smaller floods in week 3. Using ESP and reverse-ESP experiments to consider the relative influence of ASM and SubX reforecast skill, we find that ASM dominates probabilistic forecast skill only for small flood events at week 1, while SubX reforecast skill dominates for large flood events at all lead times.

Background In situations of increased need, such as mass casualty incidents (MCIs) and COVID-19, donated blood products are in shortage across the United States. Medical students are a potential pool for blood donors. The aim of this study was to determine overall attitudes of medical students at a single academic institution toward blood donation during times of increased need. Methods Three anonymous REDCap surveys were administered to all medical students at a rural academic institution. Surveys 1 and 2 were administered preceding and after an institution-wide MCI drill, in September and November 2019, respectively. Survey 3 was administered following a student-organized COVID-19 blood drive in June 2020. Multivariable analysis was performed to determine if factors, ie, experience with MCI drills and emergency medical services (EMS) training, were associated with willingness to donate blood. Furthermore, barriers to donation among those not willing to donate were assessed. Results Overall response rate for MCI surveys (surveys 1 and 2) was 38% (mean age 25.2 years and 50% women). 91% (n = 210) of respondents were willing to donate blood. Previous participation in MCI drills and EMS training was not associated with higher willingness to donate blood. Response rate for survey 3 was 15.6% (59.4% women), and 30 (31.3%) respondents indicated they did not volunteer to donate blood during the COVID-19 drive. Most common reasons for not donating were “other,” medical concerns, and being out-of-town. Conclusions Majority of medical students are willing to donate blood during times of increased need and offer a possible solution to increase blood donor pool.
An Early-Stage Colon Cancer Develops Intrabiliary Growth Type Metastasis 7 Years After Curative Colectomy

Published: April 2021

Although liver metastasis commonly occurs in patients with colorectal cancer (CRC), it is infrequent that it presents several years after curative resection for early-stage disease. Even more unusual is development of intrabiliary growth type metastasis rather than parenchymal metastasis. When this occurs, it can be mistaken for cholangiocarcinoma. We present a case in a patient with history of pT1N0M0 CRC treated with sigmoidectomy 7 years previously who presented with abdominal pain and MRI revealing left hepatic ductal dilation with no accompanying mass. With a recent normal colonoscopy and carcinoembryonic antigen, he was diagnosed with cholangiocarcinoma. Anatomic hepatic resection was performed, and final pathology with immunohistochemistry revealed staining consistent with CRC metastasis rather than cholangiocarcinoma. Intrabiliary growth type metastasis is a rare occurrence, which leads to its misdiagnosis. Patients with an intrabiliary tumor and a history of CRC should have immunohistochemistry to confirm the diagnosis to ensure appropriate adjuvant treatment and counseling.

Background Opioid analgesics remain mainstay of treatment for trauma-related pain despite growing concerns for opioid dependency or misuse. The purpose of this study was to evaluate opioid prescribing at hospital discharge after traumatic injury. Methods This is a single-center, retrospective analysis of patients ≥18 years of age admitted for ≥24 hours with a primary diagnosis of traumatic injury. Those with alcohol use disorder, polysubstance abuse, chronic opioid use, or in-hospital mortality were excluded. The primary outcome was the incidence of patients prescribed opioids at discharge. Secondary outcomes included percent of patients who received nonopioids, intensive care unit (ICU) admission, and hospital length of stay (LOS). Results Of the 927 encounters, 471 were included. The mean age was 60 ± 23 years, and 62.0% were male. The majority were blunt trauma, and 49.9% were falls. Mean initial injury severity score (ISS) was 9 ± 7.2. Of the 70.4% of patients prescribed opioids, 39.4% were discharged on opioids. Age ≥30 years, ICU admission, ISS <9, or Charlson Comorbidity Index >1 was less likely to have opioids prescribed at discharge. Most received nonopioids (93.6%) and multimodal analgesia (84.3%). The median hospital and ICU LOS were 5 (3-9) and 2 (0-4) days, respectively. Discussion Only 39.4% had opioids prescribed at discharge. Opioid-reductive strategies may decrease in-hospital and discharge opioid prescribing. While opioid analgesics remain a mainstay of trauma-associated pain management, institution-wide opioid-sparing strategies can further reduce discharge opioid prescribing after trauma.

Published: April 2021

Introduction We explore nonclinical factors affecting the amount of time from admission to the operating room for patients requiring nonelective repair of ventral hernias. Methods Using the 2005-2012 Nationwide Inpatient Sample, we identified adult patients with a primary diagnosis of ventral hernia without obstruction/gangrene, who underwent nonelective repair. The outcome variable of interest was time from admission to surgery. We performed univariate and multivariable analyses using negative binomial regression, adjusting for age, sex, race, income, insurance, admission day, comorbidity status (van Walraven score), diagnosis, procedure, hospital size, location/teaching status, and region. Results 7,253 patients met criteria, of which majority were women (n = 4,615) and white (n = 5,394). The majority of patients had private insurance (n = 3,015) followed by Medicare (n = 2,737). Median time to operation was 0 days. Univariate analysis comparing operation <1 day to ≥1 day identified significant differences in race, day of admission, insurance, length of stay, comorbidity status, hospital location, type, and size. Negative binomial regression showed that weekday admission (IRR 4.42, P < .0001), private insurance (IRR 1.53-2.66, P < .0001), rural location (IRR 1.39-1.76, P < .01), small hospital size (IRR 1.26-1.36, P < .05), white race (IRR 1.30-1.34, P < .01), healthier patients (van Walraven score IRR 1.05, P < .0001), and use of mesh (IRR 0.39-0.56, P < .02) were associated with shorter time until procedure. Conclusion Shorter time from admission to the operating room was associated with several nonclinical factors, which suggest disparities may exist. Further prospective studies are warranted to elucidate these disparities affecting patient care.

Background Intussusception is the most common cause of bowel obstruction in children aged 3 months to 6 years of age. We sought to describe patterns of incident childhood intussusception. Methods A retrospective longitudinal cohort study utilizing population-based health administrative data and a validated case definition was used to identify patients <18 years of age treated for intussusception between January 1, 1997 and December 31, 2016 in Ontario, Canada. Descriptive statistics, graphical analyses, and a Poisson regression model were performed for trend analysis. Results The overall incidence of intussusception in Ontario children (<18 years) was 3.3 cases/100,000 child years (cyrs), 95% CI [3.2.3.5]. The overall incidence increased from .9 cases/100,000 cyrs to 2.3 cases/100,000 cyrs. The highest incidence was in children aged 6-12 months at 28.9 cases/100,000 cyrs, 95% CI [26.2.31.9]. Incidence increased in all age-groups between 6 months and 5 years (at a rate of 5% to 16% per year; all P < .05). Month of year did not predict intussusception counts in a log-linear Poisson models, nor did rotavirus immunization implementation in 2011. There was a 3-fold variability across geographic areas in the province. There was a high rate of readmission for recurrence within 1 year (10.7%). Conclusion The incidence of intussusception more than doubled in Ontario from 1997 to 2016. The incidence increased for children aged between 6 months and 5 years at a rate of 5-16% per year, suggesting that an increased rate of idiopathic intussusception is responsible for the increase in the province.
Occupational Justice—Colonial Business as Usual? Indigenous Observations From Aotearoa New Zealand: La justice occupationnelle : sous régime colonial comme d’habitude? Observations d’autochtones d'Aotearoa en Nouvelle-Zélande
Authors: Emery-Whittington Isla G. 
Published: April 2021

Background. Western ideologies and systems of occupation and justice are implicated in the colonization of indigenous peoples worldwide. Yet, colonialism, racism, and privilege are minimally acknowledged and examined within occupational therapy and occupational science literature, as evidenced in uncritical development of notions of “occupational justice.” Purpose. First, to open a discussion of how and why theories and approaches to justice have developed as they have in Aotearoa New Zealand. Second, to further a burgeoning field of Indigenous perspectives and critiques of colonial theorizing within the profession, while highlighting local Indigenous justice frameworks including Te Tiriti o Waitangi and Matike Mai Aotearoa. Key Issues. Colonialism is minimally examined in occupational justice approaches and promotion. Implications. Honest examination of colonialism alongside Indigenous justice frameworks can advance critical praxes of decolonising occupation and re-connect occupation with justice and equity.

Objective The objective of this study was to assess the effects of single and multiple secondary tasks on officers’ performance and cognitive workload under normal and pursuit driving conditions. Background Motor vehicle crashes are a leading cause of police line of duty injuries and deaths. These crashes are mainly attributed to the use of in-vehicle technologies and multi-tasking while driving. Method Eighteen police officers participated in a driving simulation experiment. The experiment followed a within-subject design and assessed the effect of single or multiple secondary tasks (via the mobile computer terminal (MCT) and radio) and driving condition (normal vs. pursuit driving) on officers’ driving performance, cognitive workload, and secondary task accuracy and reaction time. Results Findings suggested that police officers are protective of their driving performance when performing secondary tasks. However, their workload and driving performance degraded in pursuit conditions as compared to normal driving situations. Officers experienced higher workload when they were engaged with secondary tasks irrespective of the task modality or type. However, they were faster but less accurate in responding to the radio as compared to the MCT. Conclusion Police officers experience high mental workload in pursuit driving situations, which can reduce their driving performance and accuracy when they are engaged in some secondary tasks. Application The findings might be helpful for police agencies, trainers, and vehicle technology manufacturers to modify the existing policies, training protocols, and design of police in-vehicle technologies in order to improve police officer safety.

Published: April 2021

Objectives Medicaid’s Early and Periodic Screening, Diagnostic and Treatment (EPSDT) pediatric benefit is designed to meet children’s medically necessary needs for care. A 2018 Centers for Medicare & Medicaid Services (CMS) Bulletin advised Medicaid programs to ensure that their dental payment policies and periodicity schedules include language that highlights that medically necessary care should be provided even if that care exceeds typical service frequency or intensity. We assessed the extent to which Medicaid agencies’ administrative documents reflect EPSDT’s flexibility requirement. Methods From August 2018 through July 2019, we retrieved dental provider manuals, periodicity schedules, and fee schedules in all 50 states and the District of Columbia; analyzed these administrative documents for consistency with the CMS advisory; and determined whether instructions were provided on how to bill for services that exceed customary frequencies or intensities. Results Dental-specific periodicity schedules were not evident in 11 states. Eighteen states did not include flexibility language, for example, as advocated by the American Academy of Pediatric Dentistry. Flexibility language was not evident in 24 dental provider manuals or in 47 fee schedules. Only 8 states provided billing instructions within fee schedules for more frequent or intensive services. Conclusion Updating Medicaid agency administrative documents—including dental provider manuals and periodicity and fee schedules—holds promise to promote individualized dental care as ensured by EPSDT.
Managing energy performance in buildings from design to operation using modelling and calibration

Published: April 2021

To manage the concerns regarding the energy performance gap in buildings, a structured and longitudinal performance assessment of buildings, covering design through to operation, is necessary. Modelling can form an integral part of this process by ensuring that a good practice design stage modelling is followed by an ongoing evaluation of operational stage performance using a robust calibration protocol. In this paper, we demonstrate, via a case study of an office building, how a good practice design stage model can be fine-tuned for operational stage using a new framework that helps validate the causes for deviations of actual performance from design intents. This paper maps the modelling based process of tracking building performance from design to operation, identifying the various types of performance gaps. Further, during the operational stage, the framework provides a systematic way to separate the effect of (i) operating conditions that are driven by the building’s actual function and occupancy as compared with the design assumptions, and (ii) the effect of potential technical issues that cause underperformance. As the identification of issues is based on energy modelling, the process requires use of advanced and well-documented simulation tools. The paper concludes with providing an outline of the software platform requirements needed to generate robust design models and their calibration for operational performance assessments. Practical application The paper’s findings are a useful guide for building industry professionals to manage the performance gap with appropriate accuracy through a robust methodology in an easy to use workflow. The methodological framework to analyse building energy performance in-use links best practice design stage modelling guidance with a robust operational stage investigation. It helps designers, contractors, building managers and other stakeholders with an understanding of procedures to follow to undertake an effective measurement and verification exercise.

ObjectiveTo examine the relationship among frailty index, hearing measures, and hearing‐related quality of life (QOL) in older recipients of cochlear implants.Study DesignCross‐sectional survey.SettingAcademic medical center.MethodsAdults aged ≥65 years at the time of receiving cochlear implants between July 13, 2000, and April 3, 2019, were asked to complete a questionnaire on hearing‐related QOL. Chart review was performed to identify patients’ characteristics. Correlations were calculated between frailty index and audiologic outcome measures as well as between speech recognition scores and QOL scores. Linear regression models were developed to examine the impact of clinical characteristics, frailty index, and hearing measures on hearing‐related QOL.ResultsData for 143 respondents were included. The mean age was 80.7 years (SD, 7.1), with a mean 27.8 years of hearing loss (SD, 17.4) before implantation. The mean frailty index was 11.1 (SD, 10.6), indicating that patients had 1 or 2 of the measured comorbidities on average. No correlation was found between lower frailty index (better health) and hearing scores, including pure tone averages (PTAs) and speech recognition scores. Lower frailty index and larger improvement in PTA after cochlear implantation predicted better QOL scores on univariate analysis (respectively, P =. 002, β = −0.42 [95% CI, −0.68 to −0.16]; P =. 008, β = −0.15 [95% CI, −0.26 to −0.04]) and multivariate analysis (P =. 047, β = −0.28 [95% CI, −0.55 to −0.01]; P =. 006, β = −0.16 [95% CI, −0.28 to −0.05]). No speech recognition scores correlated with QOL after cochlear implantation.ConclusionsFrailty index does not correlate with hearing scores after cochlear implantation in older adults. Lower frailty index and more improvement in PTA predict better QOL scores after cochlear implantation in older adults.
Effect of Anemia on Work Productivity in Both Labor- and Nonlabor-Intensive Occupations: A Systematic Narrative Synthesis
Authors: Marcus Hannah , Schauer Claudia , Zlotkin Stanley 
Published: April 2021

Background: Anemia is highly prevalent particularly in low- and middle-income countries. Iron deficiency contributes to an estimated 50% of anemia cases. Iron interventions have become central to global anemia treatment and prevention; however, few iron interventions have been scaled up to the national level, despite their proven effectiveness. While both cross-sectional and interventional studies on the effect of anemia and iron supplementation on worker productivity have been conducted, there have been few systematic reviews conducted. As such, a synthesis of previously conducted primary research is warranted and may provide a more comprehensive overview of the strength of currently available evidence, potentially helping to inform national policy on matters relating to funding and legislation for population-level iron interventions. Objectives: The objective of this study was to synthesize available evidence on the effect of both anemia and therapeutic iron interventions on productivity in working adults. Methods: All relevant English language studies were systematically obtained from both MEDLINE and EMBASE and assessed for evidence of differing productivity levels across groups stratified by iron intervention or anemia status. Potential mediating variables were reported, and the results were narratively summarized. Results: The available data from 12 included studies provide strong evidence that anemia negatively impacts occupational performance and that therapeutic iron interventions can yield substantial productivity gains. Conclusions: Despite their limitations, these findings make an important contribution to the literature highlighting the impact of iron deficiency and population-wide iron interventions on work productivity and occupational performance.

Purpose: To examine if tweeting bias exists within imaging literature by determining if diagnostic test accuracy (DTA) studies with positive titles or conclusions are tweeted more than non-positive studies. Methods: DTA studies published between October 2011 to April 2016 were included. Positivity of titles and conclusions were assessed independently and in duplicate, with disagreements resolved by consensus. A negative binomial regression analysis controlling for confounding variables was performed to assess the relationship between title or conclusion positivity and tweets an article received in the 100 days post-publication. Results: 354 DTA studies were included. Twenty-four (7%) titles and 300 (85%) conclusions were positive (or positive with qualifier); 1 (0.3%) title and 23 (7%) conclusions were negative; and 329 (93%) titles and 26 (7%) conclusions were neutral. Studies with positive, negative, and neutral titles received a mean of 0.38, 0.00, and 0.45 tweets per study; while those with positive, negative, and neutral conclusions received a mean of 0.44, 0.61, and 0.38 tweets per study. Regression coefficients were -0.05 (SE 0.46) for positive relative to non-positive titles, and -0.09 (SE 0.31) for positive relative to non-positive conclusions. The positivity of the title ( P = 0.91) or conclusion ( P = 0.76) was not significantly associated with the number of tweets an article received. Conclusions: The positivity of the title or conclusion for DTA studies does not influence the amount of tweets it receives suggesting that tweet bias is not present among imaging diagnostic accuracy studies.
