Impact of English proficiency on use of Glasgow Coma Scale in geriatric patients with traumatic brain injury.

Background: The relationship between English proficiency (EP), Glasgow Coma Scale (GCS) and traumatic brain injury (TBI) is not well characterized. We aimed to understand the impact of limited English proficiency (LEP) on the evaluation and outcomes of TBI. Methods: Retrospective comparative study in a single institution of patients aged ⪰65 who presented to the emergency department after a fall with head strike between January 2018 and December 2021. TBI was defined as documented loss of consciousness or intracranial hemorrhage (ICH). Relationships between EP, GCS, and TBI were analyzed with multivariable and propensity score-matched models. Results: Of the 2905 included, 1233 (42%) had LEP. Most LEP patients were Asian (60%) while the majority of EP patients were non-Hispanic Caucasians (72%). In a univariate analysis, LEP had higher incidence of decreased GCS and was strongly correlated with risk of TBI (OR 1.47, CI 1.26 to 1.71). After adjusting for multiple covariates including race, LEP did not have a significantly increased risk for GCS score <13 (OR 1.66, CI 0.99 to 2.76) or increased risk of TBI. In the matched analysis, LEP had a small but significantly higher risk of GCS score <13 (OR 1.03, CI 1.02 to 1.05) without an increased risk in TBI. Decreased GCS remained strongly correlated with presence of ICH in LEP patients in the adjusted model (OR 1.39, CI 1.30 to 1.50). Conclusions: LEP correlated with lower GCS in geriatric patients with TBI. This association weakened after adjusting for factors like race, suggesting racial disparities may have more influence than language differences. Moreover, GCS remained effective for predicting ICH in LEP individuals, highlighting its value with suitable translation resources. Level of evidence: This is a Level III evidence restrospective comparative study.

Uncommon Sociodemographic Factors Are Associated With Racial Disparities in Length of Stay Following Oncologic Elective Colectomy.

INTRODUCTION: Although outcome disparities by race have been identified in colorectal cancer, these patterns are challenging to explain using variables that are commonly available in databases. In a single institution serving a diverse community, length of stay (LOS) varies by race following elective oncologic colectomy. We investigated previously unexplored variables that may explain the relationship between race and LOS following elective resection of colorectal neoplasms. METHODS: Retrospective, single institution cohort study from January 2015 to December 2020 for adult patients undergoing elective colorectal cancer resections. Baseline demographic variables and intraoperative factors were analyzed for changes in LOS following elective colorectal resection. Additional retrospective chart review was carried out to determine household member composition and distance from home to hospital. Bivariate analysis was conducted to determine which variables should be included in multivariable analyses. All analyses were conducted using SAS Academic. RESULTS: Most patients (n = 383) were Asian (40%), Black (12%), or Hispanic (26%). Race and LOS were associated with age (P = 0.001 and P < 0.001 for race and LOS, respectively), American Society of Anesthesiologists class (P = 0.004 and P < 0.001), enhanced recovery after surgery protocols (P = 0.006 and P < 0.001), household members (P = 0.009 and P = 0.002), and discharge disposition (P = 0.049 and P < 0.001). In multivariable analysis, household members (P = 0.021) independently remained associated with LOS after controlling for race (P = 0.008) and discharge disposition (P < 0.001). CONCLUSIONS: Household member composition varies with LOS, suggesting that level of support at home may influence decisions regarding discharge disposition, which lead to differences in LOS.

Prehospital Assaults Against Asian Americans, Native Hawaiians, and Pacific Islanders During COVID-19.

INTRODUCTION: Anti-Asian sentiment increased when the SARS-CoV-2 virus reached the United States in 2020. Trends in national assaults occurring during the COVID-19 pandemic in the Asian American, Native Hawaiian, and Pacific Islander (AANHPI) community were evaluated. METHODS: Patients treated for assaults by emergency medical services between January 2019 and December 2021 were extracted from ImageTrend Collaborate, a national database. Multivariable logistic regression models, adjusting for age, sex, and urbanicity, were used to compare assault rates overall and in the AANHPI population. RESULTS: There were 84,825 assaults (8.5% of injury incidents) in 2019; 96,314 (9.2%) in 2020; and 97,841 (8.4%) in 2021. Assaults against AANHPI increased from 870 (7.1 assaults per 100 injuries) to 987 (8.3) and 1150 (7.9) between 2019 and 2021, respectively. Compared to 2019, risk of assaults in 2020 in all races increased (OR 1.08; 1.07, 1.10) but decreased in 2021 (OR 0.97; 0.96, 0.98). However, among AANHPI, risk of assaults increased in both 2020 (OR 1.22; 1.10, 1.35) and 2021 (OR 1.13; 1.03, 1.25). Most AANHPI assault victims were between 25 and 34 y old (11.8% in 2019) with an increase in 2020 (15.6%) and 2021 (14.4%). Assaults against AANHPI with blunt and sharp objects increased annually from 2019 to 2021. CONCLUSIONS: Despite national decreases of assaults in 2021 to pre-COVID baseline, the rate of assaults treated by emergency medical services for the AANHPI population remained elevated. Further studies analyzing in-hospital assault trends will allow for better understanding and will quantify the impact the pandemic and surrounding social influences had on minorities across the United States.

Enhanced Recovery After Surgery protocols mitigate the weekend effect on length of stay following elective colectomy.

BACKGROUND: This study aimed to determine the effect of Enhanced Recovery After Surgery (ERAS) protocols on the weekend effect after elective colectomies. METHODS: This was a retrospective study on all elective colorectal surgeries at a single institution in New York City between January 1, 2015, and December 31, 2020. The length of stay (LOS) by day of the week of surgery and the effect of ERAS using univariable and multivariable analyses were compared. RESULTS: A total of 605 patients were included in the study. Of note, 41 cases were performed on Mondays, 197 cases were performed on Tuesdays, 45 cases were performed on Wednesdays, 187 cases were performed on Thursdays, and 135 cases were performed on Fridays. Univariate analysis showed that, for patients who did not undergo ERAS, Monday and Tuesday were significantly associated with decreased LOS (P < .001). For patients who underwent ERAS, there was no statistically significant difference in LOS (P = .06) when operated on early in the week vs later. After controlling for age, race/ethnicity, comorbidities, complications, functional health status, operation type, duration of surgery, presence of ostomy, and albumin level, adhering to the ERAS protocol was significantly associated with a shorter LOS (P < .001). CONCLUSION: Our study demonstrated that ERAS can mitigate the weekend effect on LOS. ERAS protocols may provide more structure to the expected hospital course and allow patients to reach recovery milestones earlier, facilitating discharge even by covering teams.

Acute Appendicitis in the Epicenter of the COVID-19 Pandemic: A New York City Single-Center Experience.

BACKGROUND: Appendectomy is the gold standard for simple appendicitis. During the coronavirus-19 pandemic, it was estimated that appendectomies in the United States decreased by 24%. We aimed to describe trends in acute appendicitis management at a center located in one of the largest epicenters of the pandemic. METHODS: This is a retrospective cohort study in a single institution located in Queens, New York, of patients who presented with acute appendicitis. A pre-COVID time period, March-June 2019, was compared to peak-COVID, March-June 2020, and late-COVID, March-June 2021. RESULTS: Of the 382 patients admitted with appendicitis during the time periods, 164 were admitted pre-COVID. Appendicitis presentations decreased by 44% during peak-COVID and 23% in late-COVID. Patients were younger during peak-COVID compared to pre-COVID (39 vs 34 years old, P = .036). Incidence of complicated appendicitis in pre-, peak-, and late-COVID was equivalent (41% vs 46% vs 45%) and operative management was similar (85% vs 76% vs 79%). Non-operative patients had shorter lengths of stay (pre- vs peak-COVID: 4.6 vs 2.9 days, P = .006). Readmission rates were similar between the cohorts across time periods. CONCLUSIONS: During peak-COVID, there was a significant decrease in presentation of acute appendicitis but clinical presentation and outcomes remained similar between the cohorts. Patients who were managed non-operatively may be discharged earlier without increased rates of readmissions.

Outcomes of a Colorectal Enhanced Recovery After Surgery Protocol Modified for a Diverse and Urban Community.

INTRODUCTION: Enhanced recovery after surgery (ERAS) colorectal programs have been shown to improve the length of stay (LOS) without increasing hospital resource utilization at academic centers worldwide. A multidisciplinary ERAS protocol that includes preoperative, intraoperative, and postoperative management guidelines was recently implemented at our urban, racially diverse, and academically affiliated community hospital. A delivery option was provided to reduce barriers to care. Given our unique patient population, the objective of our study was to determine if improvements in outcomes were reproducible in our hospital. METHODS: This is a retrospective study of patients undergoing elective colectomy at New York-Presbyterian Queens Hospital between January 1, 2015, and December 31, 2020. Patient outcomes were compared between surgeries performed under standard practice (all colectomies prior to April 2017) and those performed after the implementation of the ERAS protocol. Demographic and perioperative data were abstracted from a prospectively derived database used to submit data to the National Surgical Quality Improvement Program. Additional data were obtained from chart review. RESULTS: Six hundred five elective colectomies were performed by 12 surgeons (range 1-228 cases) during the study period. Of these, 22 were performed open (41% followed ERAS), 467 were performed laparoscopically (57% followed ERAS), and 116 were performed robotically (74% followed ERAS). The average patient age was 64 y. Of which, 55% were male; 34% were Asian, 27% were non-Hispanic Caucasian, 27% were Hispanic, and 11% were Black or African American (all P-values > 0.05 for ERAS versus non-ERAS). Average duration of procedure was longer in the ERAS group (262 min versus 243 min, P = 0.04), although when stratified by procedure type, this relationship held true only for laparoscopic procedures. Hospital LOS was significantly shorter in the ERAS group (4.3 versus 5.4 d, P < 0.001) and this relationship held true for procedures performed both laparoscopically (4.2 versus 5.3 d, P = 0.01) and robotically (4.1 versus 5.1 d, P = 0.04). Of the ERAS group, patients who opted for delivery of ERAS components (n = 205) had the shortest LOS when compared to patients who picked up components (n = 91) or opted out of ERAS (n = 309) (4.1 versus 4.4 versus 5.2 d, P = 0.003). No significant differences were found for 30-d mortality, 30-d readmission, wound infection, or other postoperative complications (all P-values > 0.05). CONCLUSIONS: Implementation of an ERAS protocol in an urban, diverse, academically affiliated community hospital is associated with reductions in LOS for colectomies performed both laparoscopically and robotically. Facilitating ERAS compliance with a delivery option was also associated with improvements in hospital LOS. Preoperative nutrition supplementation was not associated with outcomes. No differences in mortality, readmission rates, or rates of postoperative complications were found.

Impact of Medicaid Expansion on the Diagnosis, Treatment, and Outcomes of Stage II and III Rectal Cancer Patients.

BACKGROUND: Insurance status has been associated with disparities in stage at cancer diagnosis. We examined how Medicaid expansion (ME) impacted diagnoses, surgical treatment, use of neoadjuvant therapies (NCRT), and outcomes for Stage II and III rectal cancer. STUDY DESIGN: We used 2010-2017 American College of Surgeons National Cancer Database (NCDB) to identify patients ages 18-65, with Medicaid as primary form of payment, and were diagnosed with Stage II or III rectal cancer. Patients were stratified based on Census bureau division's ME adoption rates of High, Medium, Low. Overall trends were examined, and patient characteristics and outcomes were compared before and after ME date of 1/1/2014. RESULTS: Over 8 years of NCDB data examined, there was an increasing trend of Stage II and III rectal cancer diagnoses, surgical resection, and use of NCRT for Medicaid patients. We observed an increase in age, proportion of White Medicaid patients in Low ME divisions, and proportion of fourth income quartile patients in High ME divisions. Univariate analysis showed decreased use of open surgery for all 3 categories after ME, but adjusted odds ratios (aOR) were not significant based on multivariate analysis. NCRT utilization increased after ME for all 3 ME adoption categories and aOR significantly increased for Low and High ME divisions. ME significantly decreased 90-day mortality. CONCLUSIONS: Medicaid expansion had important impacts on increasing Stage II and III rectal cancer diagnoses, use of NCRT, and decreased 90-day mortality for patients with Medicaid. Our study supports increasing health insurance coverage to improve Medicaid patient outcomes in rectal cancer care.

Repetitive Transcranial Magnetic Stimulation as a Treatment for Veterans with Cognitive Impairment and Multiple Comorbidities.

BACKGROUND: Despite decades of research efforts, current treatments for Alzheimer's disease (AD) are of limited effectiveness and do not halt the progression of the disease and associated cognitive decline. Studies have shown that repetitive transcranial magnetic stimulation (rTMS) may improve cognition. OBJECTIVE: We conducted a pilot study to investigate the effect of rTMS on cognitive function in Veterans with numerous medical comorbidities. METHODS: Participants underwent 20 sessions, over the course of approximately 4 weeks, of 10 Hz rTMS at the left dorsolateral prefrontal cortex with intensity of 120% resting motor threshold. Outcome measures including memory, language, verbal fluency, and executive functions were acquired at baseline, end of treatment, and 4 months after the last rTMS session. Twenty-six Veterans completed the study (13 in the active rTMS group, 13 in the sham rTMS group). RESULTS: The study protocol was well-tolerated. Active, compared to sham, rTMS showed improved auditory-verbal memory at the end of treatment and at 4-month follow-up. However, the active rTMS group demonstrated a trend in decreased semantic verbal fluency at the end of treatment and at 4-month follow up. CONCLUSION: These preliminary results show rTMS is safe in general in this elderly Veteran population with multiple co-morbidities. Patients in the sham group showed an expected, slight decline in the California Verbal Learning Test scores over the course of the study, whereas the active treatment group showed a slight improvement at the 4-month post-treatment follow up. These effects need to be confirmed by studies of larger sample sizes.

Simultaneous FDG-PET/MRI detects hippocampal subfield metabolic differences in AD/MCI.

The medial temporal lobe is one of the most well-studied brain regions affected by Alzheimer's disease (AD). Although the spread of neurofibrillary pathology in the hippocampus throughout the progression of AD has been thoroughly characterized and staged using histology and other imaging techniques, it has not been precisely quantified in vivo at the subfield level using simultaneous positron emission tomography (PET) and magnetic resonance imaging (MRI). Here, we investigate alterations in metabolism and volume using [18F]fluoro-deoxyglucose (FDG) and simultaneous time-of-flight (TOF) PET/MRI with hippocampal subfield analysis of AD, mild cognitive impairment (MCI), and healthy subjects. We found significant structural and metabolic changes within the hippocampus that can be sensitively assessed at the subfield level in a small cohort. While no significant differences were found between groups for whole hippocampal SUVr values (p = 0.166), we found a clear delineation in SUVr between groups in the dentate gyrus (p = 0.009). Subfield analysis may be more sensitive for detecting pathological changes using PET-MRI in AD compared to global hippocampal assessment.

Sedation mediates part of Citalopram's effect on agitation in Alzheimer's disease.

BACKGROUND: We found a benefit of citalopram for agitation in the Citalopram for Agitation in Alzheimer's Disease study (CitAD), and wondered if this was mediated by a sedative effect. CitAD was a randomized, placebo-controlled, double-blind, parallel group trial conducted at 8 academic centers in the United States and Canada from August 2009 to January 2013. One hundred sixty-two participants with probable Alzheimer's disease (AD) and clinically significant agitation were analyzed in this study. Participants received a psychosocial intervention and were randomized to receive either citalopram or placebo (approximately half assigned to each group). Participants were rated on the Neurobehavioral Rating Scale Agitation subscale and measures of sedation (i.e., fatigue and somnolence). METHODS: Using the MacArthur Foundation procedures for documenting a mediator effect, we performed a secondary analysis examining whether sedation mediates the effect of treatment on agitation outcome. RESULTS: We found a statistically significant mediating effect of sedation on agitation outcomes, but the magnitude of the effect was small, only explaining 11% of the variance in agitation, with a significant, but modest effect size of 0.16 (95% CI: 0.08 to 0.22). CONCLUSIONS: The benefit of citalopram was partly due to sedation but largely due to other mechanisms of action.

Apolipoprotein ε4 is associated with lower brain volume in cognitively normal Chinese but not white older adults.

Studying ethnically diverse groups is important for furthering our understanding of biological mechanisms of disease that may vary across human populations. The ε4 allele of apolipoprotein E (APOE ε4) is a well-established risk factor for Alzheimer's disease (AD), and may confer anatomic and functional effects years before clinical signs of cognitive decline are observed. The allele frequency of APOE ε4 varies both across and within populations, and the size of the effect it confers for dementia risk may be affected by other factors. Our objective was to investigate the role APOE ε4 plays in moderating brain volume in cognitively normal Chinese older adults, compared to older white Americans. We hypothesized that carrying APOE ε4 would be associated with reduced brain volume and that the magnitude of this effect would be different between ethnic groups. We performed whole brain analysis of structural MRIs from Chinese living in America (n = 41) and Shanghai (n = 30) and compared them to white Americans (n = 71). We found a significant interaction effect of carrying APOE ε4 and being Chinese. The APOE ε4xChinese interaction was associated with lower volume in bilateral cuneus and left middle frontal gyrus (Puncorrected<0.001), with suggestive findings in right entorhinal cortex and left hippocampus (Puncorrected<0.01), all regions that are associated with neurodegeneration in AD. After correction for multiple testing, the left cuneus remained significantly associated with the interaction effect (PFWE = 0.05). Our study suggests there is a differential effect of APOE ε4 on brain volume in Chinese versus white cognitively normal elderly adults. This represents a novel finding that, if verified in larger studies, has implications for how biological, environmental and/or lifestyle factors may modify APOE ε4 effects on the brain in diverse populations.

The Chinese Verbal Learning Test specifically assesses hippocampal state.

BACKGROUND: Recently, the Chinese Verbal Learning Test (ChVLT) was developed to assess episodic memory in Chinese speakers. The goal of this analysis was to determine whether memory consolidation as measured by the ChVLT was specifically associated with hippocampal volume in patients with cognitive impairment. METHODS: We administered the ChVLT to 22 Chinese-speaking patients with mild cognitive impairment and 9 patients with dementia and obtained hippocampal and cortical volumes from T1-weighted magnetic resonance imaging. RESULTS: Linear regression revealed that hippocampal volume explained 9.9% of the variance in delayed memory (P = .018) after controlling for the effects of age, education, immediate recall after the last learning trial, overall level of cognitive impairment, and volumes of other cortical regions. CONCLUSION: These results indicate that the ChVLT is specifically correlated with hippocampal volume, supporting its utility for detecting hippocampal disease and monitoring hippocampal state over time.

Depressive symptoms in Chinese-American subjects with cognitive impairment.

OBJECTIVES: To compare the prevalence of depressive symptoms and frequency of antidepressant use between a group of elderly Chinese-American subjects with and without cognitive impairment and a group of matched white subjects. A secondary aim was to examine the clinical and demographic predictors of depressive symptoms across these groups. METHODS: The study was conducted at an academic neurology subspecialty clinic. This was a case-control study with 140 Chinese-American subjects and 140 demographically and cognitively matched white subjects. In each group, there were 48 cognitively normal and 92 cognitively impaired participants (49 with mild cognitive impairment, 43 with Alzheimer disease). The proportion of individuals with significant depressive symptoms, as indicated by a Geriatric Depression Scale score ≥6 of 15, and frequency of antidepressant use were compared across groups by using χ(2) analysis. Factors predicting depressive symptoms, including racial and diagnostic group, age, gender, Mini-Mental State Examination score, level of functional impairment, education level, and medical comorbidities, were assessed by using linear regression analysis. RESULTS: Significant depressive symptoms were more common in cognitively impaired Chinese-American (35%) than cognitively impaired white (15%; χ(2)[1] = 9.4; p = 0.004) subjects. Chinese-American subjects with cognitive impairment were less likely to be receiving treatment for depression (12%) than white subjects with cognitive impairment (37%; χ(2)[1] = 15.6; p = 0.002). Racial and diagnostic group, age, level of functional impairment, Mini-Mental State Examination score, and education level were all statistically significant independent predictors of Geriatric Depression Scale score. CONCLUSIONS: Elderly Chinese-American subjects with cognitive impairment are at increased risk for unrecognized and untreated depressive symptoms compared with elderly white subjects with cognitive impairment. Education level may contribute to this risk or it may be a surrogate marker for other factors contributing to depressive symptoms in this group.

Frontotemporal dementia in eight Chinese individuals.

Frontotemporal dementia (FTD) has rarely been reported in Chinese populations. There are many potential reasons for this, including possible hesitancy on the part of patients or families to bring FTD-related symptoms to medical attention. Here, we present data on eight Chinese individuals, all of whom met criteria for the behavioral variant of FTD or the semantic variant of primary progressive aphasia. These patients presented for neurological evaluation at a relatively advanced stage. The mean MMSE score at initial presentation was 15. Behavioral symptoms were common and usually elicited during the medical history only after direct questioning. Delay in presentation was attributed to a variety of issues, including family disagreements about whether the symptoms represented a disease and lack of medical insurance. These cases illustrate that the symptoms of FTD in Chinese-Americans are similar to those in Caucasians but various factors, some potentially culturally relevant, may influence the likelihood and timing of clinical presentation for FTD, as well as other dementias. Additional study of FTD in diverse ethnic groups needs to address barriers to clinical presentation, including factors that may be culturally specific.
