Sex differences in chronic pain are well established with documented predominance in women. This study assessed relationships between age at menarche and chronic pain, site-specific chronic pain, pain characteristics, and chronic widespread pain (CWP). We used data from the Tromsø Study conducted in 2007 to 2008 and 2015 to 2016 (Tromsø 6 and Tromsø 7 waves) including participants aged 30 to 99 years. The associations between age at menarche and chronic pain were examined in Tromsø 6 (n = 6449), Tromsø 7 (n = 5681), and the combination of Tromsø 6 and Tromsø 7 (n = 12,130). Tromsø 7 data were used further to examine the associations between age at menarche and site-specific chronic pain, 4 pain characteristics (pain duration, pain intensity, episode duration, and episode frequency), and CWP. All analyses were adjusted for body mass index, age, and economic status of the household in childhood. Lower age at menarche was associated with an increased risk of chronic pain in all 3 samples (risk ratio for each yor pain across a broad spectrum of pain outcomes.Right ventricular assist devices (RVADs) can be used in patients with acute right heart failure. A novel device that has recently been deployed is the right atrium to pulmonary artery (RA-PA) dual lumen single cannula (DLSC). One of the limitations is that it occupies a large proportion of the right ventricular outflow tract and PA; therefore, standard continuous hemodynamic monitoring with a pulmonary artery catheter is commonly not used. Serial echocardiography is pivotal for device deployment, monitoring device position, assessing RV readiness for decannulation, and surveilling for short-term complications. We performed a retrospective case series of 24 patients with RA-PA DLSC RVAD assessing echocardiographic RV progression and vasoactive infusion requirements. The overall survival was 66.6%. The average vasoactive infusion score at the time of cannulation was 24.9 ± 43.9, at decannulation in survivors 4.6 ± 4.9 vs. 25.4 ± 21.5 in nonsurvivors, and 2.7 ± 4.9 at 48 hours post decannulation. On echocardiography, the average visual estimate of RV systolic function encoded (0 = none and 5 = severe) in survivors was 3.9 ± 1.2, 2.8 ± 1.6, 2.5 ± 1.7, and 2.8 ± 1.9, respectively, and in nonsurvivors 3.8 ± 1.6 and 3.4 ± 1.8, respectively. This demonstrated an RV systolic function improvement over time in survivors as opposed to nonsurvivors. This was also demonstrated in RV size visual estimate, respectively. Quantitatively, at the predefined four timepoints, the RVLV, tricuspid annular plane systolic excursion, and fractional area change all improve over time and there is statistically significant difference in survivors versus nonsurvivors. In this study, we describe a cohort of patients treated with RA-PA DLSC RVAD. We illustrate the critical nature of echocardiographic measures to rate the progression of RV function, improvement in vasoactive infusion requirements, and ventilator parameters with the RA-PA DLSC.There is an increasing interest in the use of bivalirudin for pediatric extracorporeal membrane oxygenation (ECMO) anticoagulation. However, dosing is not well described in those requiring continuous renal replacement therapy (CRRT). We aimed to determine whether CRRT affects bivalirudin dosing in pediatric ECMO patients. Children ≤18 years of age placed on ECMO and anticoagulated with bivalirudin for ≥24 hours from January 2019 to May 2020 were included. Bivalirudin doses were collected for 144 hours from initiation of bivalirudin or CRRT. Analysis was performed to determine whether CRRT, age, or weight affected bivalirudin dosing. Thirty-one children were included, and 11 (35%) required concomitant CRRT. There was no difference in age (median 9.1 versus 3.2 months, p = 0.15) or days on ECMO (median 11 versus 9, p = 0.7) between those who did or did not receive CRRT. The mean bivalirudin dosing was similar in patients who did or did not require CRRT (median and IQR 0.13 mg/kg/hour [0.08-0.26] versus 0.15 mg/kg/hour [0.11-0.22], respectively, p = 0.13). Younger age (p less then 0.001) and lower weight (p less then 0.001) were associated with higher bivalirudin dosing. In our study, bivalirudin dosing did not differ if the patient required CRRT while on ECMO.Driveline infection (DLI) is common after left ventricular assist device (LVAD). Limited data exist on DLI prevention and management. We investigated the impact of standardized driveline care initiatives, specific pathogens, and chronic antibiotic suppression (CAS) on DLI outcomes. 591 LVAD patients were retrospectively categorized based on driveline care initiatives implemented at our institution (2009-2019). Era (E)1 nonstandardized care; E2 standardized driveline care protocol; E3 addition of marking driveline exit site; E4 addition of "no shower" policy. 87(15%) patients developed DLI at a median (IQR) of 403(520) days. S. aureus and P. aeruginosa were the most common pathogens. 31 (36%) of DLI patients required incision and drainage (I&D) and 5 (5.7%) device exchange. P. aeruginosa significantly increased risk for initial I&D (HR 2.7, 95% CI, 1.1-6.3) and recurrent I&D or death (HR 4.2, 95% CI, 1.4-12.5). Initial I&D was associated with a significant increased risk of death (HR 2.92 (1.33-6.44); P = 0.008) when compared to patients who did not develop DLI. Implementation of standardized driveline care protocol (E2) was associated with increased 2-year freedom from DLI compared to nonstandardized care (HR 0.36, 95% CI, 0.2-0.6, P less then 0.01). Additional preventive strategies (E3&E4) showed no further reduction in DLI rates. 57(65%) DLI patients received CAS, 44% of them required escalation to intravenous antibiotics and/or I&D. Presence of P. aeruginosa DLI markedly increased risk for I&D or death. Conditional survival of patients progressing to I&D is diminished. Standardized driveline care protocol was associated with a significant reduction in DLI, while additional preventive strategies require further testing.Postinfarct ventricular septal defect (PIVSD) is associated with high mortality and the management of these patients has been a challenge with little improvement in outcomes. We commenced a protocol of veno-arterial extracorporeal membrane oxygenation (VA ECMO) for those patients who present in cardiogenic shock with the aim to improve end-organ function before definitive surgical repair to reduce postoperative mortality. This study reviewed the results of this strategy. This was a single-center, retrospective review of all patients who were admitted to our institution with PIVSD in cardiogenic shock from September 2015 to November 2019. Clinical and investigative data were evaluated. Eight patients were referred with PIVSD during this period in cardiogenic shock. One patient had an anterior PIVSD and the other seven had inferior PIVSD. EN450 mouse Six patients underwent surgical repair at a median (interquartile range, IQR) of 7 (5-8) days after initiation of VA ECMO. Two patients did not undergo surgical repair. Five patients survived after surgery and one patient died postoperatively due to multiorgan failure. Preoperative use of VA ECMO is a feasible strategy for PIVSD and may improve the results of repair.A 32-year-old man, who had developed fulminant myocarditis leading to asystole, underwent implantation of an EVAHEART 2 left ventricular assist system with a double-cuff tipless inflow cannula and a concurrent Fontan operation. Approximately 2 years after the simultaneous EVAHEART 2 implantation and the Fontan operation, the patient underwent heart transplantation. There was no device-related thromboembolism or pump malfunction under adequate antithrombotic management during the postoperative support period. Computed tomography showed no malposition of the inflow cannula irrespective of the left ventricular chamber size. Macroscopically, the left ventricular cavity of the excised heart revealed a smooth inflow ostium with appropriate intimal proliferation and without pannus or wedge thrombus formation. These findings suggest the utility of the double-cuff tipless inflow cannula for long-term clinical applications, which may lead to favorable outcomes during long-term patient management. The double-cuff tipless inflow cannula, which does not protrude into the left ventricular cavity, potentially contributes to the prevention of suction events and the collision of the inflow cannula with the interventricular septum and left ventricular free wall. Further investigation is required to confirm the role of the unique EVAHEART 2 inflow cannula in reducing thromboembolic events.Temporary mechanical circulatory support can be delivered through a variety of techniques, including percutaneous left ventricular assist devices, surgically implanted rotary pumps, and veno-arterial extracorporeal membrane oxygenation. However, limitations include the effects of high afterload, intravascular hemolysis, patient vascular anatomy, surgical morbidity, and limited patient mobility which can hinder patient recovery. We describe a series of patients managed with transapical left ventricular mechanical circulatory support using a dual lumen cannula for the management of cardiogenic shock as a bridge to recovery or definitive decision. This support strategy may represent an additional option in the care for patients with cardiogenic shock that can provide full temporary anterograde mechanical circulatory support while potentially improving patient mobility and minimizing device-related complications.Veno-venous extracorporeal membrane oxygenation (VV ECMO) has been used as a life-supporting modality for patients with severe respiratory failure because of coronavirus disease 2019 (COVID-19). We aim to evaluate the performance of the RESP score in predicting the hospital survival of COVID-19 patients undergoing VV ECMO. We performed retrospective analysis of the extracorporeal life support organization (ELSO) dataset for COVID-19 patients requiring ECMO support to evaluate the performance of RESP score in predicting in hospital survival. All adult (age ≥18) COVID-19 patients receiving VV ECMO for acute respiratory failure enrolled in the ELSO database from March to August 2020 were included in the analysis. A total of 1985 patients from the ELSO registry were identified and analyzed based on pre-ECMO variables. Median RESP score of survivors was 3 (IQR 1-5) compared to 2 (IQR 0-4) in deceased. A logistic model including RESP score variables poorly discriminated survival and death with AUC (area under curve) 0.61 (95% confidence interval 0.59-0.64). In-hospital survival for COVID-19 patients based on RESP score class from I to V was 69.7%, 59.3%, 45.7%, 42.5%, and 32.3%, respectively. Patients with immunosuppression (relative risk = 0.43) and pre-ECMO cardiac arrest (relative risk = 0.48) had lower survival. RESP score is a poor predictor of survival in COVID-19 patients undergoing ECMO. Compared to the original cohort used for RESP score creation, COVID-19 patients in RESP class I-III had worse survival whereas the patients in RESP class IV-V had better survival.
