Sex-related mortality differences in young adult septic shock patients

Septic shock survival rate and host immune response are intimately interlaced. In the last years, biological and pre-clinical studies demonstrated sex-specific differences in the immune response to infection. In the hypothesis that survival rate is related to the hormonal framework, the aim of the present study was to observe sex-specific differences in 28-day mortality rate between women of childbearing potential and same-age men. This multicenter study was conducted in six Italian intensive care units (ICUs). We enrolled consecutive patients ≤ 55 years old admitted to the Intensive Care Unit from January 2011 to January 2020, who were diagnosed with septic shock at the time of ICU admission or during the ICU stay. We gathered baseline characteristics and outcomes. The primary outcome was 28-day mortality; secondary outcomes included ICU mortality, in-hospital mortality and length of stay in the ICU and in the hospital. Moreover, data from >55 years old patients were collected and analyzed. We enrolled 361 young patients with septic shock: 215 were males (60%) and 146 females (40%). While baseline and ICU characteristics were similar between the two groups, males had a higher 28-day mortality rate (39.5% vs. 29%, p = 0.035), ICU mortality rate (49% vs. 38%, p = 0.040) and hospital mortality rate (61% vs. 50%, p = 0.040) as compared to females. Findings were confirmed in patients with septic shock at ICU admission. Young adult females developed septic shock less frequently than young males, displaying a reduced mortality rate as compared to that of their same-age male counterpart. These findings may stimulate future research and therapies

Enhancing citizens response to out-of-hospital cardiac arrest: A systematic review of mobile-phone systems to alert citizens as first responders

Introduction: Involving laypersons in response to out-of-hospital cardiac arrest through mobile-phone technology is becoming widespread in numerous countries, and different solutions were developed. We performed a systematic review on the impact of alerting citizens as first responders and to provide an overview of different strategies and technologies used. Methods: We searched electronic databases up to October 2019. Eligible studies described systems to alert citizens first responders to out-of-hospital cardiac arrest through text messages or apps. We analyzed the implementation and performance of these systems and their impact on patients\u2019 outcomes. Results: We included 28 manuscripts describing 12 different systems. The first text message system was implemented in 2006 and the first app in 2010. First responders accepted to intervene in median (interquartile) 28.7% (27\u201329%) of alerts and reached the scene after 4.6 (4.4\u20135.5) minutes for performing CPR. First responders arrived before ambulance, started CPR and attached a defibrillator in 47% (34\u201358%), 24% (23\u201327%) and 9% (6\u201314%) of cases, respectively. Pooled analysis showed that first responders activation increased layperson-CPR rates (1463/2292 [63.8%] in the intervention group vs. 1094/1989 [55.0%] in the control group; OR = 1.70; 95% CI, 1.11\u20132.60; p = 0.01) and survival to hospital discharge or at 30 days (327/2273 [14.4%] vs. 184/1955 [9.4%]; OR = 1.51; 95% CI, 1.24\u20131.84; p < 0.001). Conclusions: Alerting citizens as first responders in case of out-of-hospital cardiac arrest may reduce the intervention-free time and improve patients\u2019 outcomes

Tracheal intubation in patients at risk for cervical spinal cord injury: A systematic review

14sinoneBackground: Tracheal intubation in patients at risk for secondary spinal cord injury is potentially difficult and risky. Objectives: To compare tracheal intubation techniques in adult patients at risk for secondary cervical spinal cord injury undergoing surgery. Primary outcome was first-attempt failure rate. Secondary outcomes were time to successful intubation and procedure complications. Design: Systematic review and meta-analysis of randomized controlled trials (RCTs) with trial sequential analysis (TSA). Data Sources: Databases searched up to July 2019. Eligibility: Randomized controlled trials comparing different intubation techniques. Results: We included 18 trials enrolling 1972 patients. Four studies used the “awake” approach, but no study compared awake versus non-awake techniques. In remaining 14 RCTs, intubation was performed under general anesthesia. First-attempt failure rate was similar when comparing direct laryngoscopy or fiberoptic bronchoscopy versus other techniques. A better first-attempt failure rate was found with videolaryngoscopy and when pooling all the fiberoptic techniques together. All these results appeared not significant at TSA, suggesting inconclusive evidence. Intubating lighted stylet allowed faster intubation. Postoperative neurological complications were 0.34% (no significant difference among techniques). No life-threatening adverse event was reported; mild local complications were common (19.5%). The certainty of evidence was low to very low mainly due to high imprecision and indirectness. Conclusions: Videolaryngoscopy and fiberoptic-assisted techniques might be associated with higher first-attempt failure rate over controls. However, low to very low certainty of evidence does not allow firm conclusions on the best tracheal intubation in patients at risk for cervical spinal cord injury.noneCabrini L.; Baiardo Redaelli M.; Filippini M.; Fominskiy E.; Pasin L.; Pintaudi M.; Plumari V.P.; Putzu A.; Votta C.D.; Pallanch O.; Ball L.; Landoni G.; Pelosi P.; Zangrillo A.Cabrini, L.; Baiardo Redaelli, M.; Filippini, M.; Fominskiy, E.; Pasin, L.; Pintaudi, M.; Plumari, V.
