Incidence and variables associated with 30-day mortality after lung transplantation.

BACKGROUND: With the introduction of the lung allocation score (LAS), sicker patients are prioritized for lung transplantation (LT). There is a lack of data regarding variables independently associated with 30-day mortality after LT. METHODS: We queried the UNOS database for adult patients undergoing LT between 1989 and 2014. Patients with dual organ or previous transplantation and those with missing survival data were excluded. Mortality during the first 30 days after LT was the primary outcome variable. RESULTS: The yearly trends indicate a statistically significant reduction in the 30-day mortality during the study period (P < 0.001, overall mortality: 5.5%) which has continued in the post-LAS era (P = 0. 014, overall mortality: 3.6%). Among patients with 30-day mortality, "primary non-function" (n = 118, 72.8%) was reported as the most common etiology. Transplant indication of vascular diseases, history of non-transplant cardiac or lung surgery, mean pulmonary pressures >35 mm Hg, disabled functional status, ECMO support, high LAS, ischemic time >6 hours, and blunt injury as the mechanism of donor death are independently associated with 30-day mortality. CONCLUSION: The incidence of early mortality after LT continues to decline in the post-LAS era. Apart from the mechanism of donor death and ischemic time, early mortality appears to be primarily driven by the recipient characteristics.

Distance to invasive heart centre, performance of acute coronary angiography, and angioplasty and associated outcome in out-of-hospital cardiac arrest: a nationwide study.

AIMS: To evaluate whether the distance from the site of event to an invasive heart centre, acute coronary angiography (CAG)/percutaneous coronary intervention (PCI) and hospital-level of care (invasive heart centre vs. local hospital) is associated with survival in out-of-hospital cardiac arrest (OHCA) patients. METHODS AND RESULTS: Nationwide historical follow-up study of 41 186 unselected OHCA patients, in whom resuscitation was attempted between 2001 and 2013, identified through the Danish Cardiac Arrest Registry. We observed an increase in the proportion of patients receiving bystander CPR (18% in 2001, 60% in 2013, P < 0.001), achieving return of spontaneous circulation (ROSC) (10% in 2001, 29% in 2013, P < 0.001) and being admitted directly to an invasive centre (26% in 2001, 45% in 2013, P < 0.001). Simultaneously, 30-day survival rose from 5% in 2001 to 12% in 2013, P < 0.001. Among patients achieving ROSC, a larger proportion underwent acute CAG/PCI (5% in 2001, 27% in 2013, P < 0.001). The proportion of patients undergoing acute CAG/PCI annually in each region was defined as the CAG/PCI index. The following variables were associated with lower mortality in multivariable analyses: direct admission to invasive heart centre (HR 0.91, 95% CI: 0.89-0.93), CAG/PCI index (HR 0.33, 95% CI: 0.25-0.45), population density above 2000 per square kilometre (HR 0.94, 95% CI: 0.89-0.98), bystander CPR (HR 0.97, 95% CI: 0.95-0.99) and witnessed OHCA (HR 0.87, 95% CI: 0.85-0.89), whereas distance to the nearest invasive centre was not associated with survival. CONCLUSION: Admission to an invasive heart centre and regional performance of acute CAG/PCI were associated with improved survival in OHCA patients, whereas distance to the invasive centre was not. These results support a centralized strategy for immediate post-resuscitation care in OHCA patients.

Surprise Questions for Survival Prediction in Patients With Advanced Cancer: A Multicenter Prospective Cohort Study.

BACKGROUND: Predicting the short-term survival in cancer patients is an important issue for patients, family, and oncologists. Although the prognostic accuracy of the surprise question has value in 1-year mortality for cancer patients, the prognostic value for short-term survival has not been formally assessed. The primary aim of the present study was to assess the prognostic value of the surprise question for 7-day and 30-day survival in patients with advanced cancer. PATIENTS AND METHODS: The present multicenter prospective cohort study was conducted in Japan from September 2012 through April 2014, involving 16 palliative care units, 19 hospital-based palliative care teams, and 23 home-based palliative care services. RESULTS: We recruited 2,425 patients and included 2,361 for analysis: 912 from hospital-based palliative care teams, 895 from hospital palliative care units, and 554 from home-based palliative care services. The sensitivity, specificity, positive predictive value, and negative predictive value of the 7-day survival surprise question were 84.7% (95% confidence interval [CI], 80.7%-88.0%), 68.0% (95% CI, 67.3%-68.5%), 30.3% (95% CI, 28.9%-31.5%), and 96.4% (95% CI, 95.5%-97.2%), respectively. The sensitivity, specificity, positive predictive value, and negative predictive value for the 30-day surprise question were 95.6% (95% CI, 94.4%-96.6%), 37.0% (95% CI, 35.9%-37.9%), 57.6% (95% CI, 56.8%-58.2%), and 90.4% (95% CI, 87.7%-92.6%), respectively. CONCLUSION: Surprise questions are useful for screening patients for short survival. However, the high false-positive rates do not allow clinicians to provide definitive prognosis prediction. IMPLICATIONS FOR PRACTICE: The findings of this study indicate that clinicians can screen patients for 7- or 30-day survival using surprise questions with 90% or more sensitivity. Clinicians cannot provide accurate prognosis estimation, and all patients will not always die within the defined periods. The screened patients can be regarded as the subjects to be prepared for approaching death, and proactive discussion would be useful for such patients.

Clinical evaluation of antifungal de-escalation in Candida infections: A systematic review and meta-analysis.

OBJECTIVES: De-escalation (DES) from echinocandins to azoles is recommended by several medical societies in Candida infections. We summarise the evidence of DES on clinical and microbiological cure and 30-day survival and compare it with continuing the treatment with echinocandins (non-DES). METHODS: We searched MEDLINE, Embase, Web of Science and Scopus. Studies describing DES in inpatients and reporting any of the outcomes evaluated were included. Pooled estimates of the tree outcomes were calculated with a fixed or random-effects model. Heterogeneity was explored stratifying by subgroups and via meta-regression. This systematic review is registered with PROSPERO (CRD42023475486). RESULTS: Of 1853 records identified, 9 studies were included, totalling 1575 patients. Five studies stepped-down to fluconazole; one to voriconazole and three to any of azoles. The mean day of DES was 5.2 (4.6-6.5) days. The clinical cure OR was 1.29 (95% CI: 0.88-1.88); the microbiological cure 1.62 (95% CI: 0.71-3.71); and 30-day survival 2.17 (95% CI: 1.09-4.32). The 30-day survival data into subgroups showed higher effect on critically ill patients and serious-risk bias studies. Meta-regression did not identify significant effect modifiers. CONCLUSIONS: DES is a safe strategy; it showed no higher 30-day mortality and a trend towards greater clinical and microbiological cure.

Factors of Hospital Mortality in Men and Women with ST-Elevation Myocardial Infarction - An Observational, Retrospective, Single Centre Study.

Purpose: There are well-known gender differences in mortality of patients with ST-elevation myocardial infarction (STEMI). Our purpose was to assess factors of hospital mortality separately for men and women with STEMI, which are less well known. Patients and Methods: In 2018-2019, 485 men and 214 women with STEMI underwent treatment with primary percutaneous coronary intervention (PCI). We retrospectively compared baseline characteristics, treatments and hospital complications between men and women, as well as between nonsurviving and surviving men and women with STEMI. Results: Primary PCI was performed in 94% of men and 91.1% of women with STEMI, respectively. The in-hospital mortality was significantly higher in women than in men (14% vs 8%, p=0.019). Hospital mortality in both genders was associated significantly to older age, heart failure, prior resuscitation, acute kidney injury, to less likely performed and less successful primary PCI and additionally in men to hospital infection and in women to bleeding. In men and women ≥65 years, mortality was similar (13.3% vs 17.8%, p = 0.293). Conclusion: Factors of hospital mortality were similar in men and women with STEMI, except bleeding was more likely observed in nonsurviving women and infection in nonsurviving men.

Pneumocystis jirovecii Pneumonia in Patients with Solid Malignancies: A Retrospective Study in Two Hospitals.

Pneumocystis jirovecii pneumonia (PJP) is a rare opportunistic infection in patients with solid malignancies. This study aimed to examine the characteristics of patients with solid cancers and PJP. We retrospectively reviewed the medical records of patients with solid tumors and PJP over an 11-year period, enrolling a total of 47 patients (30-day survival group: n = 20, 30-day mortality group: n = 27). Only 34% of patients received ≥20 mg of prednisolone for ≥2 weeks, and the 30-day mortality rate was 57.4%. The 30-day survival group included more women and patients with colon cancer than the mortality group. Furthermore, absolute lymphocyte counts (ALCs) were decreased at PJP symptom onset, as compared with the values observed 1-3 months earlier. Increased oxygen demand and low ALCs after 5-7 days of PJP treatment were also related to poor prognosis. Due to the limitations of this retrospective study, further studies that adhere to the PJP criteria of the European Organization for Research and Treatment of Cancer and the Mycoses Study Group Education and Research Consortium will be needed to evaluate PJP in solid malignancies more clearly.

Efficacy of Veno-Arterial Extracorporeal Life Support in Adult Patients with Refractory Cardiogenic Shock.

Background: This study aimed to describe the efficacy of veno-arterial extracorporeal life support (VA-ECLS) through early lactate clearance and pH restoration and assess the potential association with 30-day survival following hospital discharge. Methods: Data of patients receiving VA-ECLS for at least 24 h were retrospectively compiled. Blood lactate levels, liver enzymes, and kidney parameters prior to VA-ECLS initiation and at 2, 8, 14, 20, and 26 h of support had been recorded as part of clinical care. The primary outcome was 30-day survival. Results: Of 77 patients who underwent VA-ECLS for refractory cardiogenic shock, 44.2% survived. For all non-survivors, ECLS was initiated after eight hours (p = .008). Blood pH was significantly higher in survivors compared to non-survivors at all time points except for pre-ECLS. Lactate levels were significantly lower in survivors (median range 1.95-4.70 vs 2.90-6.70 mmol/L for survivors vs non-survivors, respectively). Univariate and multivariate analyses indicated that blood pH at 24 h (OR 0.045, 95% CI: 0.005-0.448 for pH <7.35, p = .045) and lactate concentration pre-ECLS (OR 0.743, 95% CI: 0.590-0.936, p = .012) were reliable predictors for 30-day survival. Further, ischemic cardiogenic shock as ECLS indication showed 36.2% less lactate clearance compared to patients with other indications such as arrhythmia, postcardiotomy, and ECPR. Conclusion: ECLS showed to be an effective treatment in reducing blood lactate levels in patients suffering from refractory cardiogenic shock in which the outcome is influenced by the initial lactate level and pH in the early phase of the intervention.

Characteristics and outcomes of out-of-hospital cardiac arrest patients before and during the COVID-19 pandemic in Thailand.

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) remains one of the leading causes of death worldwide, and bystander CPR with public-access defibrillation improves OHCA survival outcomes. The COVID-19 pandemic has posed many challenges for emergency medical services (EMS), including the suggestion of compression-only resuscitation and recommendations for complete personal protective equipment, which have created operational difficulties and prolonged response time. However, the risk factors affecting OHCA outcomes during the pandemic are poorly defined. This study aimed to assess the characteristics and outcomes of OHCA patients before and during the COVID-19 pandemic in Thailand. METHODS: This single-center, retrospective cohort study used data from electronic medical records and EMS paper records. All OHCA patients who visited Ramathibodi Hospital's emergency department before COVID-19 (March 2018 to December 2019) and during COVID-19 (March 2020-December 2021) were identified, and the number of emergency department returns of spontaneous circulation (ED-ROSC) and characteristics in OHCA patients before and during the COVID-19 pandemic in Thailand were collected. RESULTS: A total of 136 patients were included (78 men [59.1%]; mean [SD] age, 67.9 [18] years); 60 of these were during the COVID-19 period (beginning March 2020), and 76 were before the COVID-19 period. The overall baseline characteristics that differed significantly between the two groups were bystander witness and mode of chest compression (p-values < 0.001 and < 0.001, respectively). The ED ROSC during the COVID-19 period was significantly lower than before the COVID-19 period (26.67% vs. 46.05%, adjusted OR 0.21, p-value < 0.001). There were significant differences in survival to admission between the COVID-19 period and before (25.00% and 40.79%, adjusted OR 0.26, p-value 0.005). However, 30-day survivals were not significantly different (3.3% during the COVID-19 period and 10.53% before the COVID-19 period). CONCLUSIONS: During the COVID-19 pandemic in Thailand, ED ROSC and survival to admission in out-of-hospital cardiac arrest patients were significantly reduced. Additionally, the witness responses and mode of chest compression were very different between the two groups. TRIAL REGISTRATION: This trial was retrospectively registered on 7 December 2021 in the Thai Clinical Trial Registry, identification number TCTR20211207006.

Survival to hospital discharge is equivalent to 30-day survival as a primary survival outcome for out-of-hospital cardiac arrest studies.

AIM: The 2015 Utstein guidelines stated that 30-day survival could be used as an alternative to survival to hospital discharge (STHD) as the primary survival outcome in out-of-hospital cardiac arrest (OHCA) studies. We sought to ascertain the equivalence (concordance) of these two survival outcome measures. METHODS: We conducted a population-based retrospective cohort study of OHCA patients who were attended by St John Western Australia (SJ-WA) paramedics in Perth, WA between 1999 and 2018. OHCA patients were included if they received either an attempted resuscitation by SJ-WA or bystander defibrillation; were a resident of WA; and were transported to a hospital emergency department (ED). STHD was determined through hospital record review and 30-day survival via the WA Death Registry and cemetery registration data. RESULTS: The study cohort comprised a total of 7953 OHCA patients, predominantly male (70%), with a median (IQR) age of 63 (46-77 years), a presumed cardiac arrest aetiology (78.9%), and the majority occurred in a private residence (66.8%). Survival rates were identical for STHD and 30-day survival, with both being (13.78%, 95% CI: 13.02-14.54%) (p = 0.99). The overall concordance between the two survival rates was 99.6%. There were only 30 (0.4%) discordant cases in total: 15 cases with STHD-yes but 30-day survival-no; and 15 cases with STHD-no but 30-day survival-yes. CONCLUSION: We found that STHD and 30-day survival were equivalent survival metrics in our OHCA Registry. However, given potential differences in health systems, we suggest that 30-day survival is likely to enable more reliable comparisons across jurisdictions.

A predictive score for 30-day survival for patients undergoing major lower limb amputation for peripheral arterial obstructive disease.

To analyze outcomes following major lower extremity amputations (mLEAs) for peripheral arterial obstructive disease, gangrene, infected non-healing wound and to create a risk prediction scoring system for 30-day mortality. In this single-center, retrospective, observational cohort study. All patients treated with above-the-knee amputation (AKA) or below-the-knee amputation (BKA) between January 1st, 2010 and June 30th, 2018 were identified. The primary outcome of interest was early (≤ 30 days) mortality. Secondary outcomes were postoperative complications and freedom from amputation stump revision/failure. We identified 310 (77.7%) mLEAs performed on 286 patients. There were 188 (65.7%) men and 98 (34.3%) women with a median age of 79 years (IQR, 69-83 years). We performed 257 (82.9%) AKA and 53 (17.1%) BKA. There were 49 (15.8%) early deaths, which did not differ among the age quartiles of this cohort (15.4% vs. 14.3% vs. 15.4% vs. 19.5%, P = 0.826). Binary logistic regression analysis identified age > 80 years (OR 2.24, 95% CI 1.17-4.31; P = 0.015), chronic obstructive pulmonary disease (OR 2.12, 95% CI 1.11-4.06; P = 0.023), and hemodialysis (OR 2.52, 95% CI 1.15-5.52; P = 0.021) to be associated with early mortality. The final score (range 0-10) identified two subgroups with different mortality at 30 days: lower-risk (score < 4, 10.8%), and higher-risk (score ≥ 4: 28.7%; OR 3.2, 95% CI 1.63-6.32; P < 0.001). In our experience, mLEAs still have a 14% mortality rate over the years. Our lower-risk group (score < 4) is characterized by a lower rate of perioperative death and longer survival.

Early Coronary Angiography Is Associated with Improved 30-Day Outcomes among Patients with Out-of-Hospital Cardiac Arrest.

We evaluated the association between early coronary angiography (CAG) and outcomes in resuscitated out-of-hospital cardiac arrest (OHCA) patients, by linking data from the Singapore Pan-Asian Resuscitation Outcomes Study, with a national registry of cardiac procedures. The 30-day survival and neurological outcome were compared between patients undergoing early CAG (within 1-calender day), versus patients not undergoing early CAG. Inverse probability weighted estimates (IPWE) adjusted for non-randomized CAG. Of 976 resuscitated OHCA patients of cardiac etiology between 2011-2015 (mean(SD) age 64(13) years, 73.7% males), 337 (34.5%) underwent early CAG, of whom, 230 (68.2%) underwent PCI. Those who underwent early CAG were significantly younger (60(12) vs. 66(14) years old), healthier (42% vs. 59% with heart disease; 29% vs. 44% with diabetes), more likely males (86% vs. 67%), and presented with shockable rhythms (69% vs. 36%), compared with those who did not. Early CAG with PCI was associated with better survival and neurological outcome (adjusted odds ratio 1.91 and 1.82 respectively), findings robust to IPWE adjustment. The rates of bleeding and stroke were similar. CAG with PCI within 24 h was associated with improved clinical outcomes after OHCA, without increasing complications. Further studies are required to identify the characteristics of patients who would benefit most from this invasive strategy.

A systematic review of survival following anti-cancer treatment for small cell lung cancer.

OBJECTIVES: We conducted a systematic review and meta-analysis of survival following treatment recommended by the European Society of Medical Oncology for SCLC in order to determine a benchmark for novel therapies to be compared with. MATERIALS AND METHODS: Randomized controlled trials and observational studies reporting overall survival following chemotherapy for SCLC were included. We calculated survival at 30 and 90-days along with 1-year, 2-year and median. RESULTS: We identified 160 for inclusion. There were minimal 30-day deaths. Survival was 99 % (95 %CI 98.0-99.0 %, I233.9 %, n = 77) and 90 % (95 %CI 89.0-92.0 %, I279.5 %, n = 73) at 90 days for limited (LD-SCLC) and extensive stage (ED-SCLC) respectively. The median survival for LD-SCLC was 18.1 months (95 %CI 17.0-19.1 %, I277.3 %, n = 110) and early thoracic radiotherapy (thoracic radiotherapy 18.4 months (95 %CI 17.3-19.5, I278.4 %, n = 100)) vs no radiotherapy 11.7 months (95 %CI 9.1-14.3, n = 10), prophylactic cranial irradiation (PCI 19.7 months vs No PCI 13.0 months (95 %CI 18.5-21.0, I275.7 %, n = 78 and 95 %CI 10.5-16.6, I281.1 %, n = 15 respectively)) and better performance status (PS0-1 22.5 months vs PS0-4 15.3 months (95 %CI 18.7-26.1, I272.4 %, n = 11 and 95 %CI 11.5-19.1 I277.9 %, n = 13)) augmented this. For ED-SCLC the median survival was 9.6 months (95 %CI 8.9-10.3 %, I295.2 %, n = 103) and this improved when irinotecan + cisplatin was used, however studies that used this combination were mostly conducted in Asian populations where survival was better. Survival was not improved with the addition of thoracic radiotherapy or PCI. Survival for both stages of cancer was better in modern studies and Asian cohorts. It was poorer for studies administering carboplatin + etoposide but this regimen was used in studies that had fewer patient selection criteria. CONCLUSION: Early thoracic radiotherapy and PCI should be offered to people with LD-SCLC in accordance with guideline recommendations. The benefit of the aforementioned therapies to treat ED-SCLC and the use of chemotherapy in people with poor PS is less clear.

Survival of in-hospital cardiac arrest in men and women in a large Swedish cohort.

BACKGROUND: Cardiac arrest is more common in men than women and a few studies have shown inferior 30-day survival for men than for women. The difference might relate to patient characteristics, intra arrest factors or post arrest care. AIM: To assess differences in 30-day survival between men and women after an in-hospital cardiac arrest (IHCA). MATERIAL AND METHODS: All patients ≥18 years suffering an IHCA at Karolinska University Hospital between 2007 and 2017 were included. Data regarding the IHCA, patient characteristics, Charlson co-morbidity index (CCI) and 30-day survival were obtained from electronic patient records. Differences in survival between men and women were assessed with adjusted logistic regression models and presented as Odds Ratios with 95% Confidence Intervals (OR, 95% CI). Adjustments included age, CCI, place of cardiac arrest, first rhythm, ECG-surveillance and witnessed or not. RESULTS: In all, 1639 patients suffered an IHCA, of whom 650 (40%) were women and 193 (30%) of them survived to 30 days compared to 28% of the men. No differences were found in the studied patient characteristics, intra arrest factors or post-ROSC treatments. Men had similar survival as women (crude OR 0.93 95% CI 0.74-1.15 and adjusted OR 0.77 95% CI 0.58-1.03 respectively). CONCLUSION: This cohort study illuminates an almost equal distribution in characteristics and treatment as well as outcome, 30-day survival after IHCA between men and women. However, our study confirms previous findings of disadvantageous prerequisites among women, but also indicates that preceeding vital signs differ which might indicate residual confounding.

Trends in co-morbidities and survival for in-hospital cardiac arrest -A Swedish cohort study.

OBJECTIVES: Co-morbidities affect survival after in-hospital cardiac arrests (IHCA). The risk population for IHCA, i.e. the hospitalised patients, have a doubled increase in co-morbidities over time. A similar increase in co-morbidities among IHCAs might explain the relatively poor survival ratios despite improved care. AIM: To assess changes in the burden of baseline age-adjusted Charlson co-morbidity index (ACCI) scores among IHCAs as well as to assess its impact on survival in three time periods. MATERIAL AND METHODS: All patients ≥18 years suffering an IHCA at Karolinska University Hospital between 1st January 2007 and 31st December 2015 were included. Data regarding the IHCA, patient characteristics, ACCI and 30 day survival were obtained from electronic patient records. Parameters included in ACCI were assessed as ICD-10 codes in the medical file at admission to hospital. The median ACCI with interquartile range (IQR) was presented per year. ACCI was categorised into low 0-2points, moderate 3-5points, high 6-8 points and very high ≥9 points. Differences in survival between 2007 and 2009 and 2010-2012 as well as 2013-2015 were stratified per ACCI category and assessed with adjusted logistic regression models and presented as Odds Ratios with 95% Confidence Intervals (OR, 95% CI). Adjustments included hospital site, sex, first rhythm, ECG-surveillance, witnessed or not, and location of the IHCA. RESULTS: In all, 1373 patients suffered an IHCA, of whom 376 (27%) survived at least 30 days. The ACCI remained almost constant over time at median 4, IQR 3-6. Patients with low or moderate ACCI more than doubled their survival in 2013-2015 compared to 2007-2009 (adjusted OR 2.61 95% CI1.38-4.94 and OR 1.87 95% CI 1.14-3.09 respectively). CONCLUSION: This cohort study illuminates an almost constant burden of co-morbidities over time among patients suffering an IHCA. Further, the study highlights that 30-day survival has almost doubled from 2007 to 2009 to 2013-2015 among those with low to moderate AccI.
