BACKGROUND: Spontaneous intracerebral hemorrhage (ICH) is associated with high case fatality and significant healthcare costs. Recent studies emphasize the critical role of nutritional status in affecting outcomes in neurological disorders. This study investigates the relationship between the Prognostic Nutrition Index (PNI) and in-hospital complications and case fatality among patients with ICH.
METHODS: A retrospective analysis was performed using data from the Changhua Christian Hospital Clinical Research Database between January 2015 and December 2022. Patients under 20 or over 100 years of age or with incomplete medical data were excluded. We utilized restricted cubic spline models, Kaplan-Meier survival analysis, and ROC analysis to assess the association between PNI and clinical outcomes. Propensity score matching analysis was performed to balance these clinical variables between groups.
RESULTS: In this study, 2402 patients with spontaneous ICH were assessed using the median PNI value of 42.77. The cohort was evenly divided between low and high PNI groups, predominantly male (59.1%), with an average age of 64 years. Patients with lower PNI scores at admission had higher in-hospital complications and increased 28- and 90-day case fatality rates.
CONCLUSIONS: Our study suggests that PNI could serve as a valuable marker for predicting medical complications and case fatality in patients with spontaneous ICH.

BACKGROUND: Since 2019, Coronavirus disease-2019 (COVID-19) has raised unprecedented global health crisis. The incidence and impact of atrial fibrillation (AF) on patients with COVID-19 remain unclearly defined.
METHODS: We conducted a retrospective cohort study using ICD-10 codes to identify patients with a primary diagnosis of COVID-19 with or without AF in National Inpatient Sample Database 2020. We compared the outcome of COVID-19 patients with a concurrent diagnosis of AF with those without.
OBJECTIVE: AF will adversely affect the prognosis of hospitalized COVID-19 patients.
RESULTS: A total of 211 619 patients with a primary diagnosis of COVID-19 were identified. Among these patients, 31 923 (15.08%) had a secondary diagnosis of AF. Before propensity score matching, COVID-AF cohort was older (75.8 vs. 62.2-year-old, p < .001) and had more men (57.5% vs. 52.0%, p < .001). It is associated with more comorbidities, mainly including diabetes mellitus (43.7% vs. 39.9%, p < .001), hyperlipidemia (54.6% vs. 39.8%, p < .001), chronic kidney disease (34.5% vs. 17.0%, p < .001), coronary artery disease (35.3% vs. 14.4%, p < .001), anemia (27.8% vs. 18.6%, p < .001), and cancer (4.8% vs. 3.4%, p < .001). After performing propensity score match, a total of 31 862 patients were matched within each group. COVID-AF cohort had higher inpatient mortality (22.2% vs. 15.3%, p < .001) and more complications, mainly including cardiac arrest (3.9% vs. 2.3%, p < .001), cardiogenic shock (0.9% vs. 0.3%, p < .001), hemorrhagic stroke (0.4% vs. 0.3%, p = .025), and ischemic stroke (1.3% vs. 0.7%, p < .001). COVID-AF cohort was more costly, with a longer length of stay, and a higher total charge.
CONCLUSIONS: AF is common in patients hospitalized for COVID-19, and is associated with poorer in-hospital mortality, immediate complications and increased healthcare resource utilization.

In older adults, epidemiological data on incidence rates (IR) of hospital-acquired acute kidney injury (AKI) are scarce. Also, little is known about trajectories of kidney function before hospitalization with AKI.
We used data from biennial face-to-face study visits from the prospective Berlin Initiative Study (BIS) including community-dwelling participants aged 70+ with repeat estimated glomerular filtration rate (eGFR) based on serum creatinine and cystatin C. Primary outcome was first incident of hospital-acquired AKI assessed through linked insurance claims data. In a nested case-control study, kidney function decline prior to hospitalization with and without AKI was investigated using eGFR trajectories estimated with mixed-effects models adjusted for traditional cardiovascular comorbidities.
Out of 2020 study participants (52.9% women; mean age 80.4 years) without prior AKI, 383 developed a first incident AKI, 1518 were hospitalized without AKI, and 119 were never hospitalized during a median follow-up of 8.8 years. IR per 1000 person years for hospital-acquired AKI was 26.8 (95% confidence interval (CI): 24.1-29.6); higher for men than women (33.9 (29.5-38.7) vs. 21.2 (18.1-24.6)). IR (CI) were lowest for persons aged 70-75 (13.1; 10.0-16.8) and highest for ≥ 90 years (54.6; 40.0-72.9). eGFR trajectories declined more steeply in men and women with AKI compared to men and women without AKI years before hospitalization. These differences in eGFR trajectories remained after adjustment for traditional comorbidities.
AKI is a frequent in-hospital complication in individuals aged 70 + showing a striking increase of IR with age. eGFR decline was steeper in elderly patients with AKI compared to elderly patients without AKI years prior to hospitalization emphasising the need for long-term kidney function monitoring pre-admission to improve risk stratification.

OBJECTIVE: We aimed to determine whether the prognostic value of the shock index (SI) and its derivatives is better than that of the Thrombolysis In Myocardial Infarction risk index (TRI) for predicting adverse outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).
METHODS: A total of 257 patients with STEMI undergoing primary PCI from January 2018 to June 2019 were analyzed in a retrospective cohort study. The SI, modified shock index (MSI), age SI (age × the SI), age MSI (age × the MSI), and TRI at admission were calculated. Clinical endpoints were in-hospital complications, including all-cause mortality, acute heart failure, cardiac shock, mechanical complications, re-infarction, and life-threatening arrhythmia.
RESULTS: Multivariate analyses showed that a high SI, MSI, age SI, age MSI, and TRI at admission were associated with a significantly higher rate of in-hospital complications. The predictive value of the age SI and age MSI was comparable with that of the TRI (area under the receiver operating characteristic curve: z = 1.313 and z = 0.882, respectively) for predicting in-hospital complications.
CONCLUSIONS: The age SI and age MSI appear to be similar to the TRI for predicting in-hospital complications in patients with STEMI undergoing primary PCI.

UNASSIGNED: The in-hospital death rate in cases of hip fracture ranges from 6% to 10%. Pneumonia is a serious complication for hip fracture patients that contributes to longer hospital stays and higher mortality rates; however, the prevalence and risk factors are not well established. To address this issue, the present study investigated the incidence of and risk factors for in-hospital postoperative pneumonia (IHPOP) following geriatric intertrochanteric fracture surgery.
UNASSIGNED: Information on 1495 geriatric patients (>65 years) who underwent intertrochanteric fracture surgery at our hospital between October 2014 and December 2018 was extracted from a prospective hip fracture database and reviewed. Demographic information, clinical variables including surgical data, and preoperative laboratory indices that could potentially influence IHPOP were analyzed. Receiver operating characteristic curve analysis was performed and the optimum cutoff value for quantitative data was determined. Univariate and multivariate analyses were carried out to identify risk factors for IHPOP.
UNASSIGNED: The incidence of IHPOP following geriatric intertrochanteric fracture surgery was 3.5% (53/1495 cases). The multivariate analysis showed that age >82 years (odds ratio [OR]=2.54, p=0.004), male sex (OR=2.13, p=0.017), chronic respiratory disease (OR=5.02, p<0.001), liver disease (OR=3.39, p=0.037), urinary tract infection (OR=8.46, p=0.005), creatine kinase (CK) MB>20 U/l (OR=2.31, p=0.020), B-type natriuretic peptide (BNP) ≥75 ng/l (OR=4.02, p=0.001), and d-dimer >2.26 mg/l (OR=2.69, p=0.002) were independent risks factor for the incidence of IHPOP following geriatric intertrochanteric fracture surgery.
UNASSIGNED: The incidence of IHPOP was 3.5% following geriatric intertrochanteric fracture surgery; age, male sex, chronic respiratory disease, liver disease, urinary tract infection, CKMB, BNP, and d-dimer were significant risk factors. Targeted preoperative management based on these factors could reduce the risk of IHPOP and mortality in these patients.

Takotsubo syndrome (TTS) and acute myocardial infarction (AMI) occasionally occur during hospitalization for non-cardiac diseases. However, no study has compared the clinical characteristics between in-hospital TTS and AMI. Using the Diagnosis Procedure Combination database in Japan between 2010 and 2014, we retrospectively identified eligible inpatients who were admitted for non-cardiac diseases and developed TTS (n = 230) or AMI (n = 611) as an early in-hospital complication diagnosed by coronary angiography within 7 days after admission. We examined factors associated with developing in-hospital TTS or AMI using multivariable logistic regression. We also compared 30-day and overall in-hospital mortality between patients with TTS and AMI using 1:1 propensity score matching. Despite similar age (72.7 ± 12.4 vs. 72.8 ± 10.4 years), patients with TTS were more often female (63.5 vs. 32.9%) and underweight (24.8 vs. 14.1%) and were more likely to have had impaired activities of daily living (ADL) and impaired consciousness than those with AMI. Multivariable logistic regression analysis showed that female sex [adjusted odds ratio: 4.16 (95% confidence interval: 2.73-6.34)], impaired ADL [2.33 (1.18-4.60)], chronic pulmonary disease [3.33 (1.49-7.44)], and pneumonia [3.00 (1.81-4.98)] were associated with developing TTS relative to AMI, while overweight status, aortic disease, cerebrovascular disease, peripheral arterial disease, and dyslipidemia were associated with developing AMI relative to TTS. Propensity score-matched analysis (189 pairs) showed that 30-day in-hospital mortality was not significantly different between patients with TTS and AMI (15.3 vs. 19.0%, p = 0.41), but overall in-hospital mortality was significantly lower in patients with TTS than in those with AMI (19.6 vs. 29.1%, p = 0.041). This study suggests that although in-hospital TTS and in-hospital AMI are similarly likely to occur in older patients, in-hospital TTS is more likely to occur in female patients with impaired ADL and/or respiratory disease and carries a similar 30-day mortality risk but a lower overall in-hospital mortality risk compared with in-hospital AMI. Our results indicate the importance of differentiating TTS from AMI in hospital settings.

OBJECTIVE: Diabetic foot ulcer (DFU) is a major complication in patients with diabetes mellitus and the leading cause of non-traumatic amputation in adults. Patients with DFU are usually fragile due to chronic diabetic comorbidities; therefore, tedious debridement and intervention procedures may not be well tolerated in patients with DFU. This study aimed to identify a casual relationship between in-hospital complications and treatment for limb-threatening DFUs.
METHODS: From 2009 to 2011, 1130 consecutive patients who were admitted to the Diabetic Foot Care Center in Chang Gung Medical Center were surveyed. Rates of in-hospital mortality or events that lead to transfer to the intensive care unit (ICU) for various severe complications were retrospectively analyzed.
RESULTS: Forty-seven patients (4.2%) experienced in-hospital complications (28 patients died). Major adverse cardiac events (MACE) (n=21, 44.7%) were the most common complications, followed by nosocomial infection (n=18, 38.3%). Previous myocardial infarction was a risk factor for MACE. The presentation of MACE was fulminant (eg, acute pulmonary edema, cardiogenic shock,cardiac arrest), and occurred within 10 days of admission or within 10 days following a major procedure in most cases. ST-T segment abnormality at rest was the most common presentation of electrocardiography for MACE.
CONCLUSIONS: MACE should be prevented during treatment for limb-threatening DFU in high-risk patients. Acute stress might have caused MACE during the first 10 days after admission or a major procedure.
