Altered Low Frequency Heart Rate Variability Associated with Agoraphobia in Panic Disorder:A Retrospective Study

Purpose@#This study aimed to compare the clinical features of panic disorder (PD) with comorbid agoraphobia to those of PD alone. We focused on autonomic nervous system (ANS) alterations reflected in heart rate variability (HRV) and executive function deficits reflected in the Stroop test. @*Materials and Methods@#We retrospectively compared psychometric features, Stroop test results, and resting-state HRV across three groups: a subclinical group with anxiety attack history, a PD group without agoraphobia, and a PD group with agoraphobia. The subclinical group included 10 male and 34 female, the PD without agoraphobia group included 17 male and 19 female, and the PD with agoraphobia group included 11 male and 18 female. @*Results@#The PD with agoraphobia group had higher Symptom Checklist–95 scores than the other groups. Both PD groups had longer reaction times in the Stroop test than the subclinical group. There were no significant differences in HRV parameters between the PD groups with and without agoraphobia. Compared with the subclinical group, the PD with agoraphobia group showed significantly lower values of the natural logarithm of low-frequency HRV. @*Conclusion@#Our results do not support that executive function deficits and ANS alterations are more pronounced with comorbid agoraphobia among PD groups. However, PD with agoraphobia patients showed more complex and severe clinical symptoms in their self-reports. Compared with the subclinical group, PD patients with agoraphobia showed specific features in the natural logarithm of low-frequency HRV. Our findings suggest that agoraphobia comorbidity should be considered when evaluating or treating patients with PD.

Gender differences in the association between food costs and obesity in Korean adults: an analysis of a population-based cohort

BACKGROUND/OBJECTIVES@#Prior studies, mostly conducted in Western countries, have suggested that the low cost of energy-dense foods is associated with an increased risk of obesity. This study aimed to investigate the association between food costs and obesity risk among Koreans who may have different food cost and dietary patterns than those of Western populations. @*SUBJECTS/METHODS@#We used baseline data from a cohort of 45,193 men and 83,172 women aged 40–79 years (in 2006–2013). Dietary intake information was collected using a validated food frequency questionnaire. Prudent and Western dietary patterns extracted via principal component analysis. Food cost was calculated based on Korean government data and market prices. Logistic regression analyses were performed to investigate the association of daily total, prudent, and Western food cost per calorie with obesity. @*RESULTS@#Men in the highest total food cost quintile had 15% higher odds of obesity, after adjusting for demographic characteristics and lifestyle factors (adjusted odds ratio, 1.15; 95% confidence interval, 1.08–1.22; P-trend < 0.001); however, this association was not clear in women (P-trend = 0.765). While both men and women showed positive associations between prudent food cost and obesity (P-trends < 0.001), the association between Western food cost and obesity was only significant in men (P-trend < 0.001). @*CONCLUSIONS@#In countries in which consumption of Western foods is associated with higher food costs, higher food costs are associated with an increased risk of obesity; however, this association differs between men and women.

Measuring Glutathione Regeneration Capacity in Stem Cells

Glutathione (GSH) is a chief cellular antioxidant, affecting stem cell functions. The cellular GSH level is dynamically altered by the redox buffering system and transcription factors, including NRF2. Additionally, GSH is differentially regulated in each organelle. We previously reported a protocol for monitoring the real-time GSH levels in live stem cells using the reversible GSH sensor FreSHtracer. However, GSH-based stem cell analysis needs be comprehensive and organelle-specific. Hence, in this study, we demonstrate a detailed protocol to measure the GSH regeneration capacity (GRC) in living stem cells by measuring the intensities of the FreSHtracer and the mitochondrial GSH sensor MitoFreSHtracer using a high-content screening confocal microscope. This protocol typically analyses the GRC in approximately 4 h following the seeding of the cells onto plates. This protocol is simple and quantitative. With some minor modifications, it can be employed flexibly to measure the GRC for the whole-cell area or just the mitochondria in all adherent mammalian stem cells.

Pretransplant Functional Status Predicts Postoperative Morbidity and Mortality after Liver Transplantation in Patients with Cirrhosis

Background/Aims@#This study aimed to investigate whether pretransplant frailty can predict postoperative morbidity and mortality after liver transplantation (LT) in patients with cirrhosis. @*Methods@#We retrospectively reviewed 242 patients who underwent LT between 2018 and 2020 at a tertiary hospital in Korea. @*Results@#Among them, 189 patients (78.1%) received LT from a living donor. Physical frailty at baseline was assessed by the Short Physical Performance Battery (SPPB), by which patientswere categorized into two groups: frail (SPPB <10) and non-frail (SPPB ≥10). Among the whole cohort (age, 55.0±9.2 years; male, 165 [68.2%]), 182 patients were classified as non-frail and 60 patients were classified as frail. Posttransplant survival was shorter in the frail group than the non-frail group (9.3 months vs 11.6 months). Postoperative intensive care unit stay was longer in the frail group than in the non-frail group (median, 6 days vs 4 days), and the 30-day complication rate was higher in the frail group than in the non-frail group (78.3% vs 59.3%). Frailty was an independent risk factor for posttransplant mortality (adjusted hazard ratio, 2.38; 95% confidence interval, 1.02 to 5.57). In subgroup analysis, frail patients showed lower posttransplant survival regardless of history of hepatocellular carcinoma and donor type. @*Conclusions@#Assessment of pretransplant frailty, as measured by SPPB, provides important prognostic information for clinical outcomes in cirrhotic patients undergoing LT.

A Pilot Study on the Development and the Effect of a Cognitive-Behavioral Intervention for Undergraduates at Mental Health High Risk / 정신신체의학

Objectives@#: The purpose of this study was to develop a cognitive-behavioral intervention for college students at high risk for mental health and to investigate its effect on mental health outcomes. @*Methods@#: The program was developed to reduce depressive symptoms and adverse outcomes while promoting resilience and positive effects. It consisted of eight sessions in a small group format for eight weeks. Thirty subjects at high risk for mental health participated in the program. Outcomes on the depressive symptoms, resilience, satisfaction with life, negative affect, and positive affect were evaluated at pre-and post-intervention. @*Results@#: Depressive symptom scores reduced significantly post-intervention compared to pre-intervention (t=3.51, p=0.002). Resilience scores (t=-3.65, p=0.001) and satisfaction with life scores (t=-3.00, p=0.006) increased after intervention than pre-intervention. Positive affect scores decreased post-intervention (t=2.28, p=0.031). There was no significant difference between pre-and post-intervention negative affect scores (t=-0.94, p=0.356). @*Conclusions@#: Present study demonstrated that group-based cognitive-behavioral intervention could be helpful for college students at high risk for mental health to reduce mental health symptoms and improve healthy protective factors.

An adolescent boy with epiploic appendagitis presenting with pain in the left lower quadrant lasting for more than 10 days

We report a case of a 14-year-old Korean boy presenting with pain in the left lower quadrant, persisting for over 10 days. Except for the persistent pain, no other symptoms, such as vomiting and diarrhea, were observed. In addition, laboratory findings were normal. He was eventually diagnosed with epiploic appendagitis, a rare disease in children. This case highlights the need for imaging study for early diagnosis of epiploic appendagitis or surgical emergencies in children who visit emergency departments with pain in the left lower quadrant without specific clinical findings.

Socio-economic disparity in food consumption among young children in eight South Asian and Southeast Asian countries

BACKGROUND/OBJECTIVES@#This study examined socio-economic differences in diverse food consumption among children 6–23 months of age in South Asia and Southeast Asian countries. @*SUBJECTS/METHODS@#Data from Demographic and Health Surveys in four countries in South Asia (n = 15,749) and four countries in Southeast Asia (n = 10,789) were used. Survey-design adjusted proportions were estimated for the following 10 food items: grains, legumes, dark green leafy vegetables (DGLV), vitamin A-rich fruits, vitamin A-rich vegetables, other fruits and vegetables (OFV), fish, meat, dairy, and eggs. An equity gap was defined as an arithmetic difference in the proportion of each food item consumed in the past 24-hours between the wealthiest and lowest quintiles and between rural and urban areas, denoted by percentage points (pp). @*RESULTS@#The consumption of most of the 10 food items was higher in the wealthiest quintiles and urban areas across eight countries. The size of equity gaps was greater in Southeast Asia than in South Asia, particularly for vitamin A-rich fruits (3.3–30.0 pp vs. 0.3–19.6 pp), vitamin A-rich vegetables (12.1–26.7 pp vs. 2.4–5.9 pp), meat (17.7–33.4 pp vs. 3.4–13.4 pp), and dairy (14.7–32.5 pp vs. 3.3–11.4 pp). However, the size of equity gap in egg consumption was greater in Southeast Asia than South Asia (11.2–19.8 pp vs. 11.0–26.7 pp). Relatively narrower gaps were seen in the consumption of grains (0.3–12.9 pp), DGLV (0.6–12.4 pp), and fish (0.1–16.8 pp) across all countries. @*CONCLUSIONS@#Equity gaps in food consumption differed by socio-economic status and region. Reducing equity gaps in nutrient-rich foods and utilizing regionally available food resources may increase child dietary quality.

Correlation between fish consumption and the risk of mild cognitive impairment in the elderly living in rural areas / 한국영양학회지

Purpose@#This study examines the correlation between fish consumption and the risk of mild cognitive impairment in the elderly living in rural areas. @*Methods@#The Yangpyeong cohort data collected from Yangpyeong in July 2009 and August 2010 was used as the data set. Adults greater than or equal to 60 years who have completed the Korean version of the Mini-Mental State Examination (MMSE-KC) were selected for the study. After excluding participants with less than 500 kcal of energy intake (n = 2), a total of 806 adults were enrolled as the final subjects. Cognitive function was assessed using the MMSE-KC, and dietary intake was collected using the quantitative food frequency questionnaire comprising 106 foods or food groups. @*Results@#The educational level, proportion of people who exercise, fruits and vegetable intake, and energy intake, tended to increase with fish intake among men, while increasing age resulted in decreased fish consumption. Among women, the educational level, proportion of subjects who exercise, proportion of subjects currently taking dietary supplements, fruits and vegetable intake, and energy intake, tended to increase with fish consumption, whereas increasing age showed decreasing fish consumption. Increased fish intake resulted in a higher MMSE-KC score after adjusting for the confounding variables in women (p for trend = 0.016), but no significant trend was observed between fish intake and MMSE-KC score in men. Fish intake was inversely related to the risk of mild cognitive impairment after adjusting for covariates in women (Q1 vs. Q4; odds ratio, 0.46 [0.23–0.90]; p for trend = 0.009). @*Conclusion@#This study determined that increased fish consumption is correlated with reduced risk of mild cognitive impairment in the female elderly. Further longitudinal studies with larger samples are required to determine a causal relationship between fish intake and cognitive function.

Serum vitamin D status and metabolic syndrome: a systematic review and dose-response meta-analysis

RESULTS@#The pooled estimates (95% CI) for MetS per 25-nmol/L increment in serum vitamin D concentration were 0.80 (95% CI, 0.76–0.84; I2 = 53.5) in cross-sectional studies, and 0.85 (95% CI, 0.72–0.98; I2 = 85.8) in cohort studies. Similar results were observed, irrespectively of age of study population, study location, MetS criteria, and adjustment factors. There was no publication bias for the dose-response meta-analysis of serum vitamin D concentrations and MetS. @*CONCLUSIONS@#Dose-response meta-analysis demonstrated that a 25-nmol/L increment in the serum vitamin D concentration was associated with 20% and 15% lower risks of MetS in cross-sectional studies and cohort studies, respectively.

The effect of lecturing about communication skill with standardized patient for medical students / 의료커뮤니케이션

Background@#: Effective communication between doctors and patients is very important not only for diagnosis and treatment but also for building trust. Although teaching communication skills is very important in medical schools, there are limitations such as the number of students and the uncertainty of the patient population. Therefore, this study evaluates the effect of Fishbowl method to teach communication skills to medical students, which involves the medical students communicating with standardized patients in front of a large classroom and being observed by rest of the students. @*Methods@#: This study involves 10 weeks of educating 126 fourth grade medical students and graduates. During this period, total 8 classes were taken by subjects, where each class lasts 2 hours and is conducted by observing treatments of the standardized patients on 14 clinical topics by randomly selected medical students and giving feedback on the communication skills of the selected medical students. The educational effect was evaluated based on the scores of the clinical performance examination before and after the classes. @*Results@#: The scores assessed for medical history taking before and after the training are increased by 2.45 (p<0.001) and the scores for patient-doctor relationship is increased by 7.56 (p<0.001). @*Conclusions@#: It is expected to improve the communication skills of medical students by large scale lectures with standardized patients.

Intensivists' Direct Management without Residents May Improve the Survival Rate Compared to High-Intensity Intensivist Staffing in Academic Intensive Care Units: Retrospective and Crossover Study Design

BACKGROUND@#Medical staff members are concentrated in the intensive care unit (ICU), and medical residents are essentially needed to operate the ICU. However, the recent trend has been to restrict resident working hours. This restriction may lead to a shortage of ICU staff, and there is a chance that regional academic hospitals will face running ICUs without residents in the near future.@*METHODS@#We performed a retrospective observational study (intensivist crossover design) of medical patients who were transferred to two ICUs from general wards between September 2017 and February 2019 at one academic hospital. We compared the ICU outcomes according to the ICU type (ICU with resident management under high-intensity intensivist staffing vs. ICU with direct management by intensivists without residents).@*RESULTS@#Of 314 enrolled patients, 70 were primarily managed by residents, and 244 were directly managed by intensivists. The latter patients showed better ICU mortality (29.9% vs. 42.9%, P = 0.042), lower cardiopulmonary resuscitation (CPR) (10.2% vs. 21.4%, P = 0.013), lower continuous renal replacement therapy (CRRT) (24.2% vs. 40.0%, P = 0.009), and more advanced care planning decisions before death (87.3% vs. 66.7%, P = 0.013) than the former patients. The better ICU mortality (hazard ratio, 1.641; P = 0.035), lower CPR (odds ratio [OR], 2.891; P = 0.009), lower CRRT (OR, 2.602; P = 0.005), and more advanced care planning decisions before death (OR, 4.978; P = 0.007) were also associated with intensivist direct management in the multivariate cox and logistic regression analysis.@*CONCLUSION@#Intensivist direct management might be associated with better ICU outcomes than resident management under the supervision of an intensivist. Further large-scale prospective randomized trials are required to draw a definitive conclusion.

Efficacy and Safety of Ghrelin Agonists in Patients with Diabetic Gastroparesis: A Systematic Review and Meta-Analysis

Background/Aims@#Ghrelin agonists are emerging proki-netic agents for treating gastroparesis. Although recent clini-cal trials have demonstrated their efficacy in patients with diabetic gastroparesis (DG), the impact of such agents on symptoms and gastric dysmotility remains unclear. We per-formed a systematic review and meta-analysis to evaluate the efficacy and safety of ghrelin agonists in patients with DG. @*Methods@#A search of common electronic databases (MEDLINE, Embase, and Cochrane Central Register of Con-trolled Trials) was preformed, using keyword combinations that referenced ghrelin and DG and retrieving all eligible ran-domized controlled trials (RCTs) of ghrelin agonists versus placebo in patients with DG. The primary outcome measure was the change in patient-reported overall gastroparesis symptom scores. Secondary outcomes included the change in gastric emptying time, specific symptoms related to gas-troparesis, and adverse events. A random-effects model was applied to all study outcomes. Heterogeneity among stud-ies was determined by the chi-square test and I 2 statistics. @*Results@#We selected six RCTs of patients with DG (n=557) for meta-analysis. Ghrelin agonist administration (vs pla-cebo) significantly improved overall gastroparesis symptoms (standardized mean difference, –0.34; 95% confidence interval, –0.56 to –0.13) and significantly improved symp-toms related to gastroparesis, including nausea, vomiting, early satiety, and abdominal pain. Adverse events recorded for ghrelin agonists and placebo did not differ significantly.There was no significant heterogeneity among eligible stud-ies. @*Conclusions@#Compared with placebo, ghrelin agonists are effective and well-tolerated for the treatment of DG.

Changes in Direct Healthcare Costs before and after the Diagnosis of Inflammatory Bowel Disease: A Nationwide Population-Based Study

Background/Aims@#We aimed to investigate the differences in direct healthcare costs between patients with and without inflammatory bowel disease (IBD) and changes in direct healthcare costs before and after IBD diagnosis. @*Methods@#This population-based study identified 34,167 patients with IBD (11,014 patients with Crohn’s disease and 23,153 patients with ulcerative colitis) and 102,501 age-and sex-matched subjects without IBD (the control group) from the National Health Insurance database using the International Classification of Disease, 10th revision codes and the rare intractable disease registration program codes. The mean healthcare costs per patient were analyzed for 3 years before and after IBD diagnosis, with follow-up data available until 2015. @*Results@#Total direct healthcare costs increased and peaked at $2,396 during the first year after IBD diagnosis, but subsequently dropped sharply to $1,478 during the second year after diagnosis. Total healthcare costs were higher for the IBD patients than for the control group, even in the third year before the diagnosis ($497 vs $402, p<0.001). The costs for biologics for the treatment of IBD increased steeply over time, rising from $720.8 in the first year after diagnosis to $1,249.6 in the third year after diagnosis (p<0.001). @*Conclusions@#IBD patients incurred the highest direct healthcare costs during the first year after diagnosis. IBD patients had higher costs than the control group even before diagnosis. The cost of biologics increased steeply over time, and it can be assumed that biologics could be the main driver of costs during the early period after IBD diagnosis.

Substantial risk of recurrence even after 5 recurrence-free years in early-stage hepatocellular carcinoma patients

Background/Aims@#Although hepatocellular carcinoma (HCC) is notorious for its high recurrence rate, some patients do not experience recurrence for more than 5 years after resection or radiofrequency ablation for early-stage HCC. For those with five recurrence-free period, the risk of HCC recurrence within the next 5 years remains unknown. @*Methods@#A total of 1,451 consecutive patients (median, 55 years old; males, 79.0%; hepatitis B virus-related, 79.3%) with good liver function (Child-Pugh class A) diagnosed with early-stage HCC by Barcelona Clinic Liver Cancer Staging and received radiofrequency ablation or resection as an initial treatment between 2005 and 2010 were analyzed. @*Results@#During a median follow-up period of 8.1 years, 961 patients (66.2%) experienced HCC recurrence. The cumulative recurrence rates increased to 39.7%, 60.3%, and 71.0% at 2, 5, and 10 years, respectively, and did not reach a plateau. Five years after HCC diagnosis, 487 patients were alive without experiencing a recurrence. Among them, during a median of 3.9 additional years of follow-up (range, 0.1–9.0 years), 127 patients (26.1%) experienced recurrence. The next 5-year cumulative recurrence rate (5–10 years from initial diagnosis) was 27.0%. Male sex, higher fibrosis-4 scores, and alpha-fetoprotein levels at 5 years were associated with later HCC recurrence among patients who did not experience recurrence for more than 5 years. @*Conclusions@#The HCC recurrence rate following 5 recurrence-free years after HCC treatment was high, indicating that HCC patients warrant continued HCC surveillance, even after 5 recurrence-free years.

Potential etiology, prevalence of cirrhosis, and mode of detection among patients with non-B non-C hepatocellular carcinoma in Korea

Background/Aims@#We systematically evaluated the clinical characteristics, prevalence of cirrhosis, and mode of detection in virus-unrelated (non-B non-C, NBNC) hepatocellular carcinoma (HCC) patients in Korea. @*Methods@#A total of 447 consecutive treatment-naïve NBNC-HCC adult patients who were registered at the Samsung Medical Center HCC registry in Korea from 2010 to 2013 were analyzed. NBNC was defined as negative hepatitis B surface antigen and negative anti-hepatitis C virus antibody. Presence of cirrhosis was determined based on histological, radiological, endoscopic, and serologic results. Mode of detection was classified as either under surveillance, incidental, or symptomatic. @*Results@#Heavy alcohol use was the most common potential etiology in NBNCHCC (NBNC-A, alcohol) (59.7%). Ten patients had other identifiable causes (NBNC-O, other identifiable cause) such as autoimmune hepatitis. The rest (38.0%) had no-identifiable cause (NBNC-NA-NO, non-alcohol, no-other identifiable cause). In NBNC-NA-NO group, 83.5% (96/115) of patients with available hepatitis B core immunoglobulin G antibody (HBcIgG) showed HBcIgG positivity, and 80.6% (137/170) had metabolic risk factors (diabetes, obesity, hypertension, and/ or dyslipidemia). Cirrhosis was present in 90.0%, 70.4%, and 60.0% of NBNC-O, NBNC-A, and NBNC-NA-NO patients, respectively. The proportion of patients diagnosed under surveillance was 25.5% across all patients, with specific proportions being 80.0%, 27.7%, and 18.8% for NBNC-O, NBNC-A, and NBNC-NA-NO, respectively. @*Conclusions@#Among NBNC-HCC patients, heavy alcohol use or any other identifiable cause was not found in 38.0%. These NBNC-NA-NO HCC patients showed a high prevalence of HBcIgG positivity and metabolic risk factors, suggesting that prior hepatitis B virus infection and metabolic risk factors may be major contributing factors in the hepatocarcinogenesis in NBNC-NA-NO patients.

Suitability of the Aortic Neck Anatomy for Endovascular Aneurysm Repair in Korean Patients with Abdominal Aortic Aneurysm

Purpose@#To evaluate the aortic neck anatomy in Korean patients with abdominal aortic aneurysms (AAAs). @*Materials and Methods@#We examined computed tomography scans of 343 patients with AAAs (≥5.5 cm for men or ≥5 cm for women) between 2009 and 2018. Eligibility of neck anatomy for endovascular aneurysm repair (EVAR) was assessed with the standard instructions for use (IFU) (length ≥15 mm, suprarenal angulation (SRA) ≤45°, infrarenal angulation (IRA) ≤60°, and diameter 18-32 mm) and the extended IFU (length ≥10 mm, SRA ≤60°, IRA ≤75°, and diameter 17-32 mm). @*Results@#There were 71 women (20.7%), and 61 patients (17.8%) with rupture. Women had smaller neck diameters (21.3 vs. 23.4 mm, P<0.001 for proximal neck; 22.2 vs. 24.5 mm, P<0.001 for distal neck), and higher angulations (51.5° vs. 37.8°, P<0.001 for SRA; 77.7° vs. 57.0°, P<0.001 for IRA) than men. However, the neck length was not significantly different. Patients with ruptured AAAs had shorter neck lengths (21.0 vs. 26.8 mm, P=0.005) than those with intact AAAs. However, the neck diameters and angulations were not significantly different. EVAR eligibility for standard and extended IFUs was found in 37.5% and 55.1% of men, and 11.3% and 25.4% of women (P<0.001 for both IFUs); neck anatomy was eligible in 34.0% of intact AAAs and 23.0% of ruptured AAAs (P=0.098). @*Conclusion@#A significant proportion of the Korean patients did not meet the IFU for EVAR, mainly due to the angulated neck. Women, and patients with ruptured AAAs, were less likely to meet the IFU criteria.

Clinical Features and Outcomes of Tuberculosis in Inflammatory Bowel Disease Patients Treated with Anti-tumor Necrosis Factor Therapy / 대한소화기학회지

BACKGROUND/AIMS: Anti-tumor necrosis factor (TNF) therapy is used widely for the treatment of inflammatory bowel disease (IBD). In the present study, the characteristics and outcomes of tuberculosis (TB) in IBD patients treated with anti-TNF therapy were compared with those of non-IBD TB patients.METHODS: Twenty-five IBD patients who initially developed TB during anti-TNF therapy were enrolled in this study. Seventy-five age- and gender-matched non-IBD TB patients were selected as controls in a 1:3 ratio.RESULTS: The proportion of non-respiratory symptoms was higher in the IBD patients than in the non-IBD patients (12 [48.0%] in the IBD patients vs. 15 [20.0%] in the non-IBD patients; p=0.009). Eight (32.0%) IBD patients and 19 (25.3%) non-IBD patients had extra-pulmonary lesions (p=0.516). The frequency of positive smear results for acid-fast bacilli (AFB) was significantly higher in the non-IBD patients than in the IBD patients (three [12.0%] IBD patients vs. 27 [36.0%] non-IBD patients; p=0.023). Active TB was cured in 24 (96.0%) patients in the IBD group and in 70 (93.3%) patients in the non-IBD group (p=0.409). The TB-related mortality rates were 4.0% and 1.3% in the IBD patients and non-IBD patients, respectively (p=0.439).CONCLUSIONS: The rate of extrapulmonary involvement, side effects of anti-TB medications, and clinical outcomes did not differ between the IBD patients who initially developed TB during anti-TNF therapy and non-IBD patients with TB. On the other hand, the IBD patients had a lower rate of AFB smear positivity and a higher proportion of non-respiratory symptoms.

Intensivists' Direct Management without Residents May Improve the Survival Rate Compared to High-Intensity Intensivist Staffing in Academic Intensive Care Units: Retrospective and Crossover Study Design
