The impact of rounds with a psychiatry team in the intensive care unit: A prospective observational pilot study evaluating the effects on delirium incidence and outcomes.

BACKGROUND: Delirium in the intensive care unit (ICU) is a common but serious condition that has been associated with in-hospital mortality and post-discharge psychological dysfunction. The aim of this before and after study is to determine the effect of a multidisciplinary care model entailing daily ICU rounds with a psychiatrist on the incidence of delirium and clinical outcomes. OBJECTIVE: To assess the impact of a proactive psychiatry consultation model in the surgical ICU on the incidence and duration of delirium. METHODS: This was a prospective, single institution, observational controlled cohort pilot study of adult patients admitted to a surgical ICU. A control group that received standard of care (SOC) with daily delirium prevention care bundles in the pre-intervention period was compared to an intervention group, which had a psychiatrist participate in daily ICU rounds (post-intervention period). The primary outcome was delirium incidence. The secondary outcomes were: delirium duration, ventilator days, hospital and ICU length of stay, and in-hospital mortality. RESULTS: A total of 104 patients were enrolled and equally split between SOC and intervention groups; 95 contributed to analysis. The overall incidence of ICU delirium was 19%. SOC and intervention groups had similar rates of delirium (21% vs 18%, p = 0.72). None of the secondary outcomes statistically significantly differed between the two groups. CONCLUSION: Delirium in ICU patients is a potentially preventable condition with serious sequelae. There was no difference in delirium incidence or duration between patients receiving SOC or patients who had multidisciplinary rounds with a psychiatrist.

Demographic and physiological factors associated with clinically significant eyelid edema in patients following upper eyelid surgery.

PURPOSE: To investigate demographic and physiological variables associated with clinically significant edema after upper eyelid surgery. METHODS: A retrospective chart review was performed on patients who underwent blepharoplasty or external levator advancement with or without lid crease formation between January 2018 and January 2021 at the University of Southern California. Age, sex, pertinent medical history (medications causing edema and comorbidities), and pertinent surgical procedures were all collected. Postoperative photos were graded by two independent physician graders on a newly developed photographic scale ranging from 0 (no edema) to 3 (severe edema). Clinically significant edema of the eyelids was defined as Grade 3 edema at any postoperative point or ≥ Grade 1 edema after 90 days post operation. Patients without postoperative photos were excluded. Mann-Whitney U test, Fisher's exact test, and χ2 test were used to compare groups with and without significant edema. All analyses were conducted using SAS version 9.4 (SAS Institute Inc.) with α=0.05. RESULTS: Out of 217 patients, East Asian participants had higher odds of developing edema than White participants (odds ratio, 7.92; CI, 3.15-19.93, p < 0.0001) and Hispanic participants (odds ratio, 3.47; CI, 1.51-7.97, p = 0.003). Southeast Asian participants also had higher odds of developing CSEE than White participants (odds ratio, 6.19; CI, 1.71-22.43, p = 0.006). Fifty-four (24.9%) patients had clinically significant edema. Although BMI, medical comorbidities, medication use, and age did not affect edema, there was a statistically significant relationship between race and incidence of edema (p = 0.0001). Those in the CSEE group were also more likely to require reoperation (p = 0.0143). CONCLUSIONS: There is a statistically significant relationship between Asian race and the incidence of clinically significant eyelid edema. CSEE is associated with a higher incidence of reoperation.

Relationships between physical activity, healthy eating and cortical thickness in children and young adults.

Prior neuroimaging studies have shown associations between healthy lifestyle factors and cortical thickness; however, results on the direction of this association have been inconsistent. While the majority of studies were performed in older adults within specific weight status categories, little has been reported in younger populations with a range of adiposity, including groups with healthy-weight, overweight, and obesity. Here we investigated relationships between indices of physical activity (PA) and healthy eating with cortical thickness in children and youth/young adults and examined whether these relationships differed by weight status and age groups. Study participants included 119 youth/young adults and 159 children. We hypothesized that greater levels of PA and/or healthy eating index (HEI) composite scores would be positively associated with cortical thickness, and that this association would differ in overweight or obese groups versus normal weight groups, as well as youth/young adults vs. child cohorts. Overall PA (minutes/day) was assessed using 24-hour PA recalls. HEI was calculated to assess diet quality. A structural MRI was performed, and FreeSurfer 6.0 was used to assess cortical thickness in 68 regions of interest (ROI). Mixed effects modeling was performed to investigate associations of PA or HEI with cortical thickness. FDR corrections were applied for multiple ROIs. PA was positively associated with cortical thickness in the caudal middle frontal cortex (FDR adjusted p = 0.042) and cuneus cortex (FDR adjusted p = 0.017) after controlling for sex, age group, and weight status. When stratified by age, in youth/young adults, higher time spent in PA was associated with greater cortical thickness in the frontal, temporal, parietal and occipital cortex, after adjusting for sex and weight group (FDR adjusted ps < 0.05). No significant associations between PA and cortical thickness were observed in children. No significant associations between PA and cortical thickness were observed when stratified by weight group. No significant associations between HEI and cortical thickness were observed. These results indicate that higher time spent in PA is associated with greater cortical thickness, a relationship that appears to be stronger during youth/young adulthood and may be related to more favorable brain health outcomes.

A retrospective data analysis on the induction medications used in trauma rapid sequence intubations and their effects on outcomes.

PURPOSE: Rapid sequence intubation (RSI) in trauma patients is common; however, the induction agents used have been debated. We determined which induction medications were used most frequently for adult trauma RSIs and their associations with hemodynamics and outcomes. We hypothesized that etomidate is the most commonly used induction agent and has similar outcomes to other induction agents. METHODS: This retrospective review at two U.S. level I trauma centers evaluated adult trauma patients undergoing RSI within 24 h of admission, between 01/01/2016 and 12/31/2017. We compared patient characteristics and outcomes by induction agent. Comparisons on the primary outcome of in-hospital mortality and secondary outcomes of peri-intubation hypotension, hospital and ICU length of stay (LOS), ventilator days, and complications used logistic regression or negative binomial regression. Regression models adjusted for hospital site, age, patient severity measures, and intubation location. RESULTS: Among 1303 trauma patients undergoing RSI within 24 h of admission, 948 (73%) were intubated in the emergency department (ED) and 325 (25%) in the operating room (OR). The most common induction agents were etomidate (68%), propofol (17%), and ketamine (11%). In-hospital mortality was highest in the etomidate group (25.5%), followed by ketamine (17%), and propofol (1.8%). CONCLUSION: Etomidate was most commonly used in ED intubations; propofol was most used in the OR. Compared to propofol, patients induced with etomidate had higher mortality and complication rates. Findings should be interpreted with caution given limited generalizability and residual confounding by indication.

Primary signet ring cell histology does not portend worse survival for early stage lung cancer following lobectomy.

INTRODUCTION: Signet ring cell (SRC) histology is considered a poor prognostic factor in various cancers. However, primary SRC lung adenocarcinoma is rare and poorly understood. METHODS: The National Cancer Database was queried to identify treatment-naïve patients who received lobectomy for primary SRC or non-SRC pT1-2N0 lung adenocarcinoma <4 cm within four months of diagnosis. SRC lung adenocarcinoma was defined by ICD-O-3 code 8490, while non-SRC lung adenocarcinoma was defined by ICD-O-3 codes 8140, 8141, 8143, 8147, 8255, 8260, 8310, 8481, 8560, and 8570-8574. The Kaplan-Meier curve and log-rank test was used to compare five-year OS between SRC versus non-SRC lung adenocarcinoma cohorts. The impact of SRC histology on risk of death was assessed using the Cox proportional hazards regression model. RESULTS: 48,399 patients were included in this study: 62 with primary SRC lung adenocarcinoma and 48,337 with non-SRC lung adenocarcinoma. The mean age of the overall cohort was 67.0 ± 9.6 years. Five-year OS following lobectomy did not differ significantly between SRC lung adenocarcinoma and non-SRC lung adenocarcinoma cohorts (SRC 73.9% vs. non-SRC 69.3%, p = 0.64). SRC histology did not significantly impact risk of death within five years after lobectomy (HR 0.89, p = 0.66). CONCLUSIONS: Following lobectomy for pT1-2N0 tumors <4 cm, patients with primary SRC lung adenocarcinoma do not experience worse five-year OS or increased risk of death within five years relative to those with non-SRC lung adenocarcinoma. Additional study, including exploration of emerging molecular profiling data, may serve to better define optimal treatment for this histopathologic group of lung adenocarcinomas.

Parental decisions following prenatal diagnosis of sex chromosome aneuploidy in Hong Kong.

AIM: According to the published work, pregnancy termination rates due to prenatal diagnosis of fetal sex chromosome aneuploidies (SCA) vary widely. Some potentially modifiable and non-modifiable factors have been reported to be associated with parental decision. This study aimed to evaluate the rate of pregnancy termination for fetal SCA and the factors influencing parents' decisions in Hong Kong. METHODS: This was a 21-year retrospective cohort study of parents' decisions following prenatal diagnosis of SCA. Univariate and multivariate analyses for the association between demographic factors, prenatal factors, or counseling provided and decision-making were conducted. RESULTS: The study included 399 pregnancies with prenatal diagnosis of SCA and the overall termination rate was 55.6% (91.7%, 48.0%, 23.4%, 4.8%, and 22.7% for 45,X, 47,XXY, 47,XXX, 47,XYY, and mosaicism, respectively). Pregnancies with ultrasound abnormalities were associated with higher termination rates than pregnancies with normal ultrasound findings (91.3% vs 28.3%, P < 0.0001). From multivariate regression analysis on 226 pregnancies with normal ultrasound examination, a higher likelihood to terminate was found in pregnancies affected by 45,X and 47,XXY (adjusted odds ratio, 4.72, P < 0.0001). Increased maternal age and history of infertility were associated with lower likelihood to terminate (adjusted odds ratio, 0.9, P = 0.012; and 5.12, P = 0.038, respectively). The pregnancy termination rate declined over time. CONCLUSION: A significant correlation was found between the termination of SCA-affected pregnancy and the presence of fetal sonographic abnormalities, type of SCA, maternal age, and presence of infertility.
