COVID-19 deaths in dental occupations and other healthcare occupations among U.S. decedents in 2020.

Early studies during the COVID-19 pandemic suggested dental occupations were among the highest risk for exposure to SARs-CoV-2 because of multiple factors increasing exposure, including close proximity to unmasked patients and performance of aerosol-generating procedures. However, to date, few studies have investigated COVID-19 deaths in United States dental occupations, and compared COVID-19 deaths among healthcare occupations. We analyzed 2020 mortality data collected by the National Center for Health Statistics' National Vital Statistics System. Multivariable logistic regression was used to generate odds ratios (ORs) and 95% confidence intervals for COVID-19 as the underlying cause of death in relation to occupation in working-age decedents (≤65 years), after adjusting for age, sex, race/ethnicity, education, and medical conditions associated with severe COVID-19. Dental occupations did not have significantly higher risk for COVID-19 death when compared to all other occupations combined. Among healthcare occupations with frequent, direct patient- or client interactions, LPNs and LVNs, and speech and language pathologists had significantly elevated adjusted ORs for COVID-19 death when compared to dentists, dental hygienists, or dental assistants. Similarly, nurse practitioners had significantly higher ORs for COVID-19 mortality than dentists or dental hygienists, and approached significance when compared to dental assistants. Conversely, massage therapists and other health diagnosing and treating practitioners had significantly lower adjusted ORs for COVID-19 death compared with dental occupations. Our study highlights potential differences in work-related transmission of SARs-CoV-2 and subsequent COVID-19 deaths in healthcare occupations, and furthers a previously limited understanding of COVID-19 deaths in healthcare occupations in 2020, before COVID-19 vaccine availability. Our results indicate that dental occupations were not among the highest, nor lowest risk, healthcare occupations for COVID-19 deaths in 2020, despite their known risks of direct exposure.

Efficacy of COVID-19 Oral antivirals in hospitalised oldest-old with high morbidity burden: a target trial emulation study.

Molnupiravir and nirmatrelvir-ritonavir are orally administered pharmacotherapies for mild to moderate COVID-19. However, the effectiveness of these drugs among very old (≥80years), hospitalised patients remains unclear, limiting the risk-benefit assessment of these antivirals in this specific group. This study investigates the effectiveness of these antivirals in reducing mortality among this group of hospitalised patients with COVID-19. Using a territory-wide public healthcare database in Hong Kong, a target trial emulation study was conducted with data from 13 642 eligible participants for the molnupiravir trial and 9553 for the nirmatrelvir-ritonavir trial. The primary outcome was all-cause mortality. Immortal time and confounding bias was minimised using cloning-censoring-weighting approach. Mortality odds ratios were estimated by pooled logistic regression after adjusting confounding biases by stabilised inverse probability weights. Both molnupiravir (HR: 0.895, 95% CI: 0.826-0.970) and nirmatrelvir-ritonavir (HR: 0.804, 95% CI: 0.678-0.955) demonstrated moderate mortality risk reduction among oldest-old hospitalised patients. No significant interaction was observed between oral antiviral treatment and vaccination status. The 28-day risk of mortality was lower in initiators than non-initiators for both molnupiravir (risk difference: -1.09%, 95% CI: -2.29, 0.11) and nirmatrelvir-ritonavir (risk difference: -1.71%, 95% CI: -3.30, -0.16) trials. The effectiveness of these medications was observed regardless of the patients' prior vaccination status. Molnupiravir and nirmatrelvir-ritonavir are moderately effective in reducing mortality risk among hospitalised oldest-old patients with COVID-19, regardless of their vaccination status.

Down syndrome and associated atrioventricular septal defects in a nationwide Norwegian cohort: Prevalence, time trends, and outcomes.

The prevalence of Down syndrome (DS) is approximately 1 per 1000 births and is influenced by increasing maternal age over the last few decades. DS is strongly associated with congenital heart defects (CHDs), especially atrioventricular septal defect (AVSD). Our objectives were to investigate the prevalence of live-born infants with DS having a severe CHD in the Norwegian population over the last 20 years and compare outcomes in infants with AVSD with and without DS. Information on all births from January 1, 2000 to December 31, 2019 was obtained from the Medical Birth Registry of Norway. We also obtained data on all infants with severe CHDs in Norway registered in Oslo University Hospital's Clinical Registry for Congenital Heart Defects during 2000-2019 and accessed individual-level patient data from the electronic hospital records of selected cases. Infants with AVSD and DS were compared to infants with AVSD without chromosomal defects. Crude and adjusted odds ratios (ORs) of infant mortality and need for surgery during the first year of life, with associated 95% confidence intervals (CIs), were estimated by logistic regression. A total of 1 177 926 infants were live-born in Norway during the study period. Among these, 1456 (0.1%) had DS. The prevalence of infants with DS having a severe CHDs was relatively stable, with a mean of 17 cases per year. The most common CHD associated with DS was AVSD (44.4%). Infants with AVSD and DS were more likely to have cardiac intervention during their first year of life compared to infants with AVSD without chromosomal defects (adjusted OR [aOR]: 2.52; 95% CI 1.27, 4.98). However, we observed no difference in infant mortality during first year of life between the two groups (aOR: 1.08; 95% CI 0.43, 2.70). The prevalence of live-born infants with severe CHDs and DS has been stable in Norway across 20 years. Infants with AVSD and DS did not have higher risk of mortality during their first year of life compared to infants with AVSD without chromosomal defects, despite a higher risk of operative intervention.

The optimal degree of core temperature for hypothermic circulatory arrest in complex aortic arch surgery: results from 1310 patients.

The optimal core temperature for hypothermic circulatory arrest during aortic arch surgery remains contentious. This study aims to evaluate patient outcomes under various temperatures within a large single-centre cohort. Between 2010 and 2018, patients diagnosed with type A aortic dissection underwent total arch replacement at Fuwai Hospital were enrolled. They were categorized into 4 groups: deep hypothermia group, low-moderate hypothermia group, high-moderate hypothermia group and mild hypothermia group. Clinical data were analysed to ascertain differences between the groups. A total of 1310 patients were included in this cohort. Operative mortality stood at 6.9% (90/1310), with a higher incidence observed in the deep hypothermia group [29 (12.9%); 35 (6.9%); 21 (4.8%); 5 (3.4%); all adjusted P < 0.05]. Overall 10-year survival was 80.3%. Long-term outcomes did not significantly differ among the groups. Multivariable logistic analysis revealed a protective effect of higher core temperature on operative mortality (odds ratio 0.848, 95% confidence interval 0.766-0.939; P = 0.001). High-moderate hypothermia emerged as an independent protective factor for operative mortality (odds ratio 0.303, 95% confidence interval 0.126-0.727; P = 0.007). Multivariable Cox analysis did not detect an effect of hypothermic circulatory arrest on long-term survival (all P > 0.05). High-moderate hypothermia (24.1-28°C) offers the most effective protection against surgical mortality and is therefore recommended. Different hypothermic circulatory arrest temperatures do not influence long-term survival or quality of life.

The effectiveness of HALP score in predicting mortality in non-ST-elevation myocardial infarction patients.

The HALP score, measured based on hemoglobin, albumin, lymphocyte, and platelet levels, is regarded as a novel scoring system that indicates the status of systemic inflammation and nutritional health. Our study aimed to evaluate the relationship between HALP score and prognosis in non-ST-elevation myocardial infarction (NSTEMI) patients. Between 1 January 2020 and 1 January 2022, 568 consecutive patients diagnosed with NSTEMI from a single center were included in the study retrospectively. The patients were divided into two equal groups according to the median HALP cutoff value of 44.05. Patients were followed for at least 1 year from the date of admission. The average age of the patients was 62.3 ± 10.6 years and 43.7% were female. In-hospital and 1-year mortality were found to be significantly higher in the group with low HALP scores (6.0 vs. 2.1%, P = 0.019 and 22.5 vs. 9.9%, P < 0.001, respectively). In receiver operating characteristic curve analysis, a cutoff level of 34.6 of the HALP score predicted 1-year mortality with 71% sensitivity and 65% specificity (area under the curve: 0.707, 95% confidence interval: 0.651-0.762, P < 0.001). In Kaplan-Meier analysis, higher mortality rates were observed over time in the group with lower HALP scores (log-rank test=16.767, P < 0.001). In Cox regression analysis, the HALP score was found to be an independent predictor of 1-year mortality (odds ratio: 0.969, 95% confidence interval: 0.958-0.981, P < 0.001). We found that a low HALP score could predict in-hospital and 1-year mortality in patients admitted to the hospital with a diagnosis of NSTEMI.

Clinical and microbiological characteristics of anaerobic bacteremia during 1994–2019: A Danish population-based cohort study

ObjectivesBacteremia with anaerobic bacteria is generally a marker of severe prognosis. However, population-based data is lacking. Our aim was to describe the epidemiology and the 30-day mortality rate of anaerobic bacteremia in a Danish population-based setting. MethodsIn this population-based cohort study, all first-time episodes of anaerobic bacteremia from the North Denmark Bacteremia Research Database during 1994–2019 were identified. Information on comorbidities, discharge diagnoses, and mortality was retrieved. 30-day mortality rates were calculated and a multivariate logistic regression analysis to identify risk factors for death was performed. Results1750 episodes with anaerobic bacteremia were identified, corresponding to an incidence rate of 12.5 per 100,000 inhabitants (increasing from 11.2 in 1994–2014 to 17.7 in 2015–2019). Of these episodes, a third were polymicrobial, and the majority (70 %) of patients had one or more comorbid conditions. Abdominal infection was the source of bacteremia in 61 % of patients, while it was unknown for 15 %. The most frequently isolated genera were Bacteroides (45 %), Clostridium (20 %) and Fusobacterium (6 %). The overall crude 30-day mortality rate was 27 %, but rates were even higher for patients of high age, with liver disease, and solid tumors. The odds ratio (OR) for 30-day mortality was 1.32 for Clostridium species, and 1.27 for polymicrobial bacteremia with aerobic bacteria. ConclusionsThe incidence rate of anaerobic bacteremia increased, and the 30-day mortality rate remained high during the study period. Multiple factors influence 30-day mortality rates, including high age, liver disease, solid tumor, polymicrobial bacteremia, and bacteremia with Clostridium species.

Effects of early surgery for cervical fracture dislocation on 30-day mortality using the Japanese Diagnosis Procedure Combination database.

Retrospective study of data abstracted from the Diagnosis Procedure Combination (DPC) database. This study aimed to investigate the effects of surgery in the early phase. The optimal timing of surgery for cervical fracture dislocation (CFD) remains unclear because only a few clinical studies with approximately 100 patients have been published. This study included 4,653 adult patients with a definitive diagnosis of CFD from the DPC database. The database contains nationwide inpatient data collected from >1,000 acute care hospitals in Japan. The DPC database contains information regarding hospitalization, such as diagnosis, treatment, medical history, complications, and hospitalization outcomes. This study identified 460 pairs of patients after one-to-one propensity-score matching (PSM). Treatment outcomes were compared between patients who underwent surgery for CFD within 72 hours (early group) and later (delayed group) after admission. The main outcomes included 30-day mortality, inhospital death, and major complications. The secondary outcomes were improvement in the Barthel index, length of hospital stay, and discharged home rate. After adjusting for PSM, the early group had a significantly higher 30-day mortality rates than the delayed group (3.0% vs. 0.4%, p=0.006). In the multivariate logistic regression analysis after PSM, the early group was associated with an increased risk of 30-day mortality (odds ratio, 8.05; 95% confidence interval, 2.15-5.26; p=0.007). This study indicated that early surgery for CFD resulted in increased 30-day mortality.

A decade of robotic beating-heart totally endoscopic coronary bypass (TECAB) at a single institution: Outcomes with 10-year follow-up

ObjectiveRobotic beating-heart totally endoscopic coronary bypass (TECAB) is performed using single or bilateral internal thoracic arteries with good results. Despite slow adoption and limited industry support, we have evolved our practice and continue to routinely perform TECAB. We describe our series of 874 patients undergoing robotic beating-heart TECAB with up to 10-year follow-up. MethodsA retrospective review of all patients (n = 874) undergoing robotic beating-heart TECAB (July 2013 to April 2024) was performed. Patients were contacted for midterm follow-up, and angiographic data were collected in those undergoing hybrid revascularization. Multivariate regression analysis and Cox proportional hazard modeling were used to analyze risk factors for early/midterm outcomes. Primary end points were midterm all-cause mortality and major adverse cardiac/cerebrovascular events. ResultsMean Society of Thoracic Surgeons score was 1.5 ± 2.2%. In total, 470 (54%) underwent multivessel TECAB, of whom 86% received bilateral internal thoracic arteries. There was 1 intraoperative conversion (0.11%). Mean length of stay was 2.3 ± 0.8 days. Hospital mortality was 0.80% (observed/expected 0.54). A total of 393 patients (45%) underwent hybrid revascularization. Early graft patency was 97% (left internal thoracic artery-left anterior descending artery patency 98%). Midterm follow-up was 100% at mean 48 months (longest 10.6 years). Cardiac-related mortality and all-cause mortality were 2.2% and 18%, respectively. Freedom from major adverse cardiac/cerebrovascular events was 93%. In multivariate analysis, left-main disease ≥70% was a risk factor for midterm cardiac mortality (odds ratio, 6.7; confidence interval, 1.9-24, P = .003). ConclusionsIn this series of 874 patients with up to 10-year follow-up, we show that robotic TECAB can be performed with excellent early and midterm results using an iterative approach, despite significant challenges. Further industry support and wider surgeon adoption are necessary to ensure sustainability of this procedure.

Bleeding and long-term survival after lung resections: nationwide observational cohort study.

Bleeding following lung surgery can lead to reoperation and blood transfusions, potentially impairing outcomes. This study aimed to assess how bleeding complications affect long-term survival and postoperative complications in a nationwide contemporary group of patients undergoing lung resections. Adult patients who underwent lung resections, for both malignant and nonmalignant diagnoses, between 2013-2021, were included from the Swedish national registry for thoracic surgery. Patients with bleeding complications, defined as requiring reexploration and/or transfusions, were compared to patients without bleeding complications regarding long-term survival and postoperative complications. We used propensity scores and optimal full matching to account for differences in baseline characteristics between the groups. The cohort comprised 15,617 adult patients, of which 646 patients (4.1%) had bleeding complications. The unadjusted 90-day mortality was 9.4% vs. 1.0% in the bleeding group vs. no bleeding group, respectively. After matching, the odds ratio (OR) for 90-day mortality in the bleeding group compared with the no bleeding group was 3.66 [95% confidence interval (CI): 2.17-6.17]. Long term overall survival was lower among patients in the bleeding group, adjusted hazard ratio (95% CI) for all-cause mortality was 1.47 (1.29-1.69). Postoperative complications were more common in the bleeding group (OR: 3.00, 95% CI: 2.38-3.79), including infections (OR: 2.80, 95% CI: 1.86-4.20). Bleeding complications were more frequent during the first third of the study time period as compared to the last third (P<0.001). Patients with bleeding complications had reduced long-term survival and higher incidence of postoperative complications. A declining trend in bleeding rates over time was noted.

Effect of Preoperative Clopidogrel on Outcomes of Isolated Coronary Artery Bypass Graft: An STS National Database Analysis

BackgroundWe analyzed The Society of Thoracic Surgeons Database to investigate risks and optimal timing for coronary artery bypass grafting (CABG) after clopidogrel administration. MethodsPatients were categorized based on clopidogrel use within 5 days and further stratified by days from the last dose (0 to 5 days). Controls were patients who did not receive clopidogrel within 5 days of surgery. The primary outcome was operative mortality, and secondary outcomes included mediastinal reexploration for bleeding and blood product use. ResultsAmong 148,317 isolated CABG, 19,553 patients (13.2%) received clopidogrel within 5 days. Minimal differences in operative mortality (2.8% vs 2.1%, P < .001), but higher rates of mediastinal reexploration (3.5% vs 2.1%, P < .001) and blood product utilization (72.7% vs 56.8%, P < .001) were observed in the clopidogrel group. The adjusted odds ratio of operative mortality peaked on the day of clopidogrel administration but was comparable to controls thereafter. The odds of reexploration were highest on day 0, decreasing gradually to a plateau after day 3. Patients who underwent operations on day 3 after clopidogrel administration had similar odds of operative mortality and mediastinal reexploration for bleeding and shorter total and preoperative lengths of stay but higher blood product use compared with day 5. ConclusionsCABG within 5 days from clopidogrel is associated with a modest increase in operative mortality and reexploration for bleeding and a substantial increase in blood product use. Risks decreased with increasing time from discontinuation, plateauing after 3 days from clopidogrel. CABG at 3 days yields comparable outcomes as 5 days, reducing the waiting period.

Association between Age-Adjusted Endothelial Activation and Stress Index and Intensive Care Unit Mortality in Patients with Severe COVID-19.

Endothelial activation and stress index (EASIX) reflects endothelial dysfunction or damage. Because endothelial dysfunction is one of the key mechanisms, a few studies have shown the clinical usefulness of original and age-adjusted EASIX (age-EASIX) in patients with coronavirus disease 2019 (COVID-19). We aimed to evaluate the clinical utility of age-EASIX in predicting intensive care unit (ICU) mortality in critically ill patients with COVID-19 in South Korea. Secondary analysis was performed using clinical data retrospectively collected from 22 nationwide hospitals in South Korea between January 1, 2020, and August 31, 2021. Patients were at least 19 years old and admitted to the ICU for severe COVID-19, demanding at least high-flow nasal cannula oxygen therapy. EASIX [lactate dehydrogenase (U/L)×creatinine (mg/dL)/platelet count (109 cells/L)] and age-EASIX (EASIX×age) were calculated and log2-transformed. The mean age of 908 critically ill patients with COVID-19 was 67.4 years with 59.7% male sex. The mean log2 age-EASIX was 7.38±1.45. Non-survivors (n=222, 24.4%) in the ICU had a significantly higher log2 age-EASIX than of survivors (8.2±1.52 vs. 7.1±1.32, p&lt;0.001). log2 age-EASIX was significantly associated with ICU mortality (odds ratio, 1.541; 95% confidence interval, 1.322 to 1.796; p&lt;0.001) and had a better area under the receiver operating characteristic curve than of the sequential organ failure assessment (SOFA) score in predicting ICU mortality (0.730 vs. 0.660, p=0.001). Age-EASIX is significantly associated with ICU mortality and has better discriminatory ability than the SOFA score in predicting ICU mortality.

Effectiveness of vacuum-assisted wound closure and mesh-mediated fascial traction in open abdomen management.

To determine the effectiveness of vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) in patients undergoing open abdomen management (OAM). Data from cases with OAM for at least five days who were admitted to our institution between January 2011 and December 2020 were included. We compared the patient's age, sex, medical history, indication for initial surgery, APACHE II scores, indication for OAM, operative time, intraoperative blood loss, intraoperative transfusion, success of primary fascial closure (rectus fascial closure and bilateral anterior rectus abdominis sheath turnover flap method), success of planned ventral hernia, duration of OAM, and in-hospital mortality between patients undergoing VAWCM (VAWCM cases, n = 27) and vacuum-assisted wound closure (VAWC) alone (VAWC cases, n = 25). VAWCM cases had a significantly higher success rate of primary fascial closure (70% vs. 36%, p = 0.030) and lower in-hospital mortality (26% vs. 72%, p = 0.002) than VAWC cases. A multivariate logistic regression analysis showed that VAWCM was an independent factor influencing in-hospital mortality (odds ratio, 0.14; 95% confidence interval: 0.04-0.53; p = 0.004). VAWCM is associated with an increased rate of successful primary fascial closure and may reduce in-hospital mortality.

Door-to-antibiotic time and mortality in patients with sepsis: Systematic review and meta-analysis

ObjectivesTo evaluate whether the timing of initial antibiotic administration in patients with sepsis in hospital affects mortality. MethodsThis systematic review and meta-analysis included studies from inception up to 19 May 2022. Interventional and observational studies including adult human patients with suspected or confirmed sepsis and reported time of antibiotic administration with mortality were included. Data were extracted by two independent reviewers. Summary estimates were calculated by using random-effects model. The primary outcome was mortality. ResultsWe included 42 studies comprising 190,896 patients with sepsis. Pooled data showed that the OR for patient mortality who received antibiotics ≤1 hr was 0.83 (95 %CI: 0.67 to 1.04) when compared with patients who received antibiotics >1hr. Significant reductions in the risk of death in patients with earlier antibiotic administration were observed in patients ≤3 hrs versus >3 hrs (OR: 0.80, 95 %CI: 0.68 to 0.94) and ≤6 hrs vs 6 hrs (OR: 0.57, 95 %CI: 0.39 to 0.82). ConclusionsOur findings show an improvement in mortality in sepsis patients with early administration of antibiotics at <3 and <6 hrs. Thus, these results suggest that antibiotics should be administered within 3 hrs of sepsis recognition or ED arrival regardless of the presence or absence of shock.

Pediatric Hematology and Oncology Patients on Extracorporeal Membrane Oxygenation: Outcomes in a Multicenter, Retrospective Cohort, 2009-2021.

To describe characteristics associated with survival for pediatric patients with an oncologic diagnosis or hematopoietic cell transplant (HCT) supported with extracorporeal membrane oxygenation (ECMO). Multicenter, retrospective study. Sixteen PICUs in the United States and Israel. We included patients aged younger than 19 years with an oncologic diagnosis or HCT who required ECMO support between 2009 and 2021. None. A total of 149 patients were included in the study cohort. There were 118 patients with an oncologic diagnosis and 31 that received HCT. The indications for ECMO were respiratory failure (46%), combined respiratory and cardiac failure (28%), and cardiac failure (25%). Venovenous (V-V) ECMO was used in 45% of patients, with 53% of patients being placed on venoarterial (V-A) ECMO. For oncologic and HCT groups, survival to ECMO decannulation was 52% (62/118) and 64% (20/31), and survival to hospital discharge was 36% (43/118) and 42% (13/31), respectively. After adjusting for other factors, requiring cardiopulmonary resuscitation was associated with greater odds ratio of mortality (3.0 [95% CI, 1.2-7.7]). Survival to ECMO decannulation of pediatric oncologic and HCT patients in this study was 52-64%, depending upon diagnosis. However, survival to hospital discharge remains poor. Future research should prioritize understanding factors contributing to this survival gap within these patient populations.

All-cause 30-day mortality associated with hysterectomy in Sweden from 2015 to 2021 using data from the Swedish perioperative register

ObjectiveHysterectomy is one of the most common gynaecological procedures. All-cause mortality within 30 days is an important indicator of care quality.The primary objectives of this quality project were to study all-cause 30-day mortality following hysterectomy in Sweden and the impact of age, ASA class, and malignant indication on outcomes. Population and methodsAll hysterectomy procedures documented in the Swedish Perioperative Register (SPOR) were included from 2015 to 01-01 until 2021-12-31. Patient demographics and perioperative observations were collected and analysed. Main outcome measureAll-cause 30-day mortality. ResultsThe study cohort consisted of 25,391 patients with a mean age of 55.0 ± 13.8, and 54 % of patients were ASA I-II. All-cause 30-day mortality was low: only 1 patient died within the first 24 h, and 23 deaths were noted within 30 days among 25,391 procedures studied; equal to a perioperative mortality rate (POMR) 0.09 %. Higher age, higher ASA class, malignant indication, and combined general and neuraxial anaesthesia increased numerical POMR. Elderly (>65-years) and ASA III-IV were associated with significant increased un- and adjusted Odds Ratio for death within 30-days at 4.3 (95%CI 1.3–14.3, p = 0.02) and 15.3 (95%CI 4.8–84.4, p = 0.001) respectively. ConclusionsAll-cause 30-day mortality associated with hysterectomy in Sweden during recent years is low with a POMR of 0.09 %. Higher age and more pronounced higher ASA class increased the odds ratio for all-cause 30-day mortality. Further efforts to optimise the perioperative care of elderly and frail patients are important.

Outcomes of Patients With Newly Diagnosed AML and Hyperleukocytosis.

AML presenting with hyperleukocytosis is associated with poor outcomes. We aim to understand the factors associated with early mortality and overall survival (OS) to help guide management and improve early mortality. We retrospectively reviewed data from 129 consecutive patients with newly diagnosed AML and a WBC count ≥100 × 109/L between January 2010 and April 2020. Logistic regression models estimated odds ratios for 4-week mortality. Cox proportional hazard models estimated hazard ratios for OS. The median age was 65 years (range, 23-86); the median WBC was 146 × 109/L (range, 100-687). Seventy-five (58%) patients had clinical leukostasis (CL). FLT3, NPM1, and RAS pathway mutations were detected in 63%, 45%, and 27% of patients, respectively. Cytoreduction consisted of hydroxyurea in 124 (96%) patients, cytarabine in 69 (54%), and leukapheresis in 31 (24%). The cumulative 4-week and 8-week mortality rates were 9% and 13%, respectively, all in patients age 65 years and older. By multivariate analysis, older age, CL, and thrombocytopenia <40 × 109/L were independently associated with a higher 4-week mortality rate. After a median follow-up of 49.4 months, the median OS was 14.3 months (95% CI, 7 to 21.6), with 4-year OS of 29%. Age 65 years and older, CL, tumor lysis syndrome, elevated LDH ≥2,000 U/L, elevated lactate ≥2.2 mmol/L, and poor-risk cytogenetics were independent factors associated with worse OS. Hyperleukocytosis is a life-threatening hematologic emergency. Early recognition and intervention including cytoreduction, blood product support, antibiotics, and renal replacement therapy may help mitigate the risk of morbidity and early mortality.

Gender differences in presentation, management, and outcomes among Egyptian patients with acute coronary syndrome: a single-centre registry

BackgroundDespite a significant rise in cardiovascular disease (CVD)-related mortality in low- and middle-income countries (LMICs), data are scarce regarding the quality of care provided, particularly for women.MethodsThis is a prospective observational, cross-sectional study. Acute coronary syndrome (ACS) patients presented to the Cardiology Department at Tanta University, Egypt, between September 1, 2023, and December 31, 2023, were enrolled. The study assessed gender disparities by comparing men and women regarding presentation, management, and major adverse cardiovascular events (MACE) occurrence during hospitalization and 30 days after discharge.ResultsA total of 400 ACS patients were included, with 29.5% being women. Women were comparatively older (59 ± 9 years vs. 55 ± 13 years), with a significantly higher prevalence of hypertension (70.3% vs. 47.5%) and diabetes (55% vs. 36.8%). Non-ST-segment elevation myocardial infarction (Non-STEMI) was more common in women (35.29% vs. 21%). Dyspnea was expressed by 34.4% of women (vs. 21.35% of men). Women were hospitalized later (9.29 h vs. 6.74 h). In-hospital outcomes were poorer for women with worse NYHA classes III and IV. Additionally, the odds ratio (OR) for in-hospital cardiac mortality was 0.303 (95% CI 0.103–0.893) for women compared to men. However, a one-month follow-up for MACE post-hospital discharge did not indicate significant gender differences.ConclusionsThe current study suggests that women with ACS in Egypt exhibit a higher risk profile for CVD compared to men and tend to present later with atypical symptoms. Women additionally experience poorer in-hospital MACE and higher cardiac mortality. Therefore, increasing awareness about ACS syndrome and eliminating obstacles that delay hospital admission are imperative.

Inpatient mortality and outcomes of COVID-19 among patients with non-ischemic cardiomyopathy: A propensity matched analysis

BackgroundPatients with chronic medical conditions, particularly cardiovascular diseases, are at a greater risk of adverse outcomes due to COVID-19. The effect of COVID-19 on patients with non-ischemic cardiomyopathy (NICM) is not known well. ObjectivesTo study the impact of COVID-19 infection on NICM hospital mortality and other outcomes. MethodsThis study included a cohort of patients from the 2020 and 2021 National Inpatient Sample databases. Patients hospitalized for COVID-19 with and without NICM were matched using a 1:1 propensity score-matching ratio. Outcomes analyzed were in-hospital mortality, rates of acute kidney injury (AKI), acute myocardial infarction (AMI), cardiogenic shock, cardiac arrest, mechanical ventilation, tracheal intubation, pulmonary embolism (PE), ventricular tachycardia (VT), ventricular fibrillation (VF), length of stay (LOS), and total hospitalization charges. ResultsA total of 2,532,652 patients met the inclusion criteria (1,199,008 females [47.3 %], predominantly white 1,456,203 (57.5 %); mean [SD] age 63 [5.4] years), including 64,155 (2.5 %) patients with a history of NICM. Following propensity matching, 10,258 COVID-19 patients with and without NICM were matched. Patients with NICM had higher rates of AMI (11.1 vs. 7.1 %, p < 0.001), cardiogenic shock (2 vs. 0.6 %, p < 0.001), cardiac arrest (4.4 vs. 3.2 %, p < 0.01), mechanical ventilation (13.7 vs 12 %, p < 0.01), VT (8.5 vs. 2.2 %, p < 0.001), and VF (1.0 vs 0.25 %, p < 0.001). The odds ratios for in-hospital mortality, AKI, and PE did not differ significantly. ConclusionA History of NICM does not affect COVID-19 mortality but increases the risk of cardiovascular complications.

Role of the Stress Index in Predicting Mortality among Patients with Traumatic Femoral Fractures.

Traumatic femoral fractures, often resulting from high-energy impacts such as traffic accidents, necessitate immediate management to avoid severe complications. The Stress Index (SI), defined as the glucose-to-potassium ratio, serves as a predictor of mortality and adverse outcomes in various trauma contexts. This study aims to evaluate the prognostic value of the SI in patients with traumatic femoral fractures. This retrospective cohort study included adult trauma patients aged 20 or above with traumatic femoral fractures from the Trauma Registry System at a level 1 trauma center in southern Taiwan between 1 January 2009 and 31 December 2022. At the emergency room, serum electrolyte levels were assessed using baseline laboratory testing. By dividing blood glucose (mg/dL) by potassium (mEq/L), the SI was calculated. The best cut-off value of the SI for predicting mortality was determined using the Area Under the Curve (AUC) of Receiver Operating Characteristic (ROC). A total of 3717 patients made up the final group, of which 3653 survived and 64 died. In comparison to survivors, deceased patients had substantially higher blood glucose levels (199.3 vs. 159.0 mg/dL, p < 0.001) and SIs (53.1 vs. 41.6, p < 0.001). The optimal SI cut-off value for predicting mortality was 49.7, with a sensitivity of 53.1% and a specificity of 78.7% (AUC = 0.609). High SI was associated with increased mortality (4.2% vs. 1.0%, p < 0.001) and longer hospital stays (12.8 vs. 9.5 days, p < 0.001). The adjusted odds ratios of mortality, controlled by comorbidities, the Glasgow Coma Scale, and the Injury Severity Score, were significantly higher in patients with a higher SI (AOR 2.05, p = 0.016) than those with a lower SI. Elevated SI upon admission correlates with higher mortality and extended hospital stay in patients with traumatic femoral fractures. Although the SI has a moderate predictive value, it remains a useful early risk assessment tool, necessitating further prospective, multi-center studies for validation and standardization.

The prevalence, risk factors, and outcomes of acute pulmonary embolism complicating sepsis and septic shock: a national inpatient sample analysis

The study aimed to evaluate the prevalence, risk factors, and clinical outcomes of pulmonary embolism in patients diagnosed with sepsis with and without shock. The National Inpatient Sample was used to identify adults with sepsis with and without shock between 2017 and 2019. The prevalence of acute pulmonary embolism and the association of acute pulmonary embolism with in-hospital mortality, hospital length of stay for survivors, and overall costs of hospitalization were evaluated. Multivariable logistic and linear regression analyses, adjusted for various parameters, were used to explore these associations. Of the estimated 5,019,369 sepsis hospitalizations, 1.2% of patients with sepsis without shock and 2.3% of patients with septic shock developed pulmonary embolism. The odds ratio for in-hospital mortality was 1.94 (95% confidence interval (CI) 1.85–2.03, p < 0.001). The coefficient for hospital length of stay was 3.24 (95% CI 3.03–3.45, p < 0.001). The coefficient for total costs was 46,513 (95% CI 43,079–49,947, p < 0.001). The prevalence of pulmonary embolism in patients diagnosed with sepsis with and without shock was 1.2 and 2.3%, respectively. Acute pulmonary embolism was associated with higher in-hospital mortality, longer hospital length of stay for survivors, and higher overall costs of hospitalization.
