RESUMEN
Background: Since its outbreak, the COVID-19-pandemic has had a tremendous impact on healthcare systems worldwide. We conducted a comparative study to analyze the pandemic's consequence on microsurgical reconstructions at a reconstructive plastic surgery center in Sweden. Method: All free flaps performed at a single center between March 2019 and 2021 were analyzed. The patient cohort was divided into two groups, with a period of 1 year in each group: non-COVID-19 year and COVID-19 year. The periods were compared regarding the number and type of surgeries and patient characteristics. Results: In the year prior to the pandemic, 123 free flap surgeries were performed, compared with 103 surgeries during the COVID-19 year. There was a significant shift in the most common site for free flap reconstruction: from the breast [which decreased by 42% (66-38)] to head and neck [which increased by 22% (41-50); OR 0.53 (P = 0.02)]. This was also reflected by a significant increase in hospital stay for free flap patients during the COVID-19 year (P = 0.02). Conclusions: During the COVID-19 pandemic, a shift was seen from breast reconstructions toward head and neck reconstructions as the most common free flap procedure performed. An increasing backlog of elective breast reconstructions demands increased resources and tougher priorities, which challenge the healthcare system in the post-COVID-19 era.
RESUMEN
Autologous free tissue transfer is today an integral part of reconstructive plastic surgery, but still lacks generally accepted guidelines regarding antithrombotic agents. We hypothesized that the overuse of antithrombotic agents could be a risk factor for free flap complications and therefore studied a treatment protocol adjustment. METHODS: Consecutive free flaps between 2005 and 2020 at a single center were analyzed for complications in relation to the use of pre- and intraoperative treatment with three different antithrombotic agents. The use of preoperative low molecular weight heparin (LMWH), intraoperative heparin, and dextran were analyzed in relation to outcome variables, thromboembolic events, or reexploration for hematoma. RESULTS: Nine hundred thirty-one patients underwent 1000 microvascular free flaps for breast (n = 487), head and neck (n = 365), and extremity (n = 148) reconstruction. Within the first postoperative week, 44 cases had a thromboembolic event and 58 cases underwent hematoma-related reexploration. In the multivariate analysis, thromboembolic events were associated with extremity reconstruction (P = 0.02) and smoking (P = 0.02). Hematoma-related reexploration was more common with triple antithrombotic therapy compared with all other treatment regimes (P < 0.05). The number of antithrombotic agents used perioperatively was linearly decreased, from three to none, over the elapsed time period (P < 0.001). CONCLUSIONS: Hematoma was the most common reason for reexploration and was further associated with the use of multiple antithrombotic agents. Cessation of triple treatment was associated with less hematomas and further reduction of antithrombotic agents did not result in any increase of thromboembolic events. Evidence-based guidelines are warranted for antithrombotic regimes in standard free flap surgery.
RESUMEN
BACKGROUND: Secondary prevention after acute coronary syndrome (ACS) is essential to reduce morbidity and mortality, but related studies have been fairly small or performed as clinical trials with non-representative patient selection. Long-term follow-up data are also minimal. A nurse-led follow-up for risk factor improvement may be effective, but the evidence is limited. OBJECTIVE: The aims of this study are to perform an adequately sized, nurse-led, long-term secondary preventive follow-up with inclusion of an unselected population of ACS patients. The focus will be on lipid and blood pressure control as well as tobacco use and physical activity. METHODS: The study will consist of a randomized, controlled, long-term, population-based trial with two parallel groups. Patients will be included during the initial hospital stay. Important outcome variables are total cholesterol, low-density lipoprotein (LDL) cholesterol, and sitting systolic and diastolic blood pressure. Outcomes will be measured after 12, 24, and 36 months of follow-up. Trained nurses will manage the intervention group with the aim of achieving set treatment goals as soon as possible. The control group will receive usual care. At least 250 patients will be included in each group to reliably detect a difference in mean LDL of 0.5 mmol/L and in mean systolic blood pressure of 5 mmHg. RESULTS: The study is ongoing and recruitment of participants will continue until December 31, 2014. CONCLUSIONS: This study will test the hypothesis that a nurse-led, long-term follow-up after an ACS with a focus on achieving treatment goals as soon as possible is an effective secondary preventive method. If proven effective, this method could be implemented in general practice at a low cost.

RESUMEN
BACKGROUND: Incidence, any trend over time, and predictors of ischemic stroke after an acute myocardial infarction (AMI) in diabetic patients are unknown. METHODS AND RESULTS: Data for 173,233 unselected patients with an AMI, including 33,503 patients with diabetes mellitus, were taken from the Swedish Register of Information and Knowledge about Swedish Heart Intensive Care Admissions (RIKS-HIA) during 1998 to 2008. Ischemic stroke events were recorded during 1 year of follow-up. Patients with diabetes mellitus more often had a history of cardiovascular disease, received less reperfusion therapy, and were treated with acetylsalicylic acid, P2Y12 inhibitors, and statins to a lesser extent compared with patients without diabetes mellitus. However, the use of evidence-based therapies increased markedly in both groups during the study period. The incidence of ischemic stroke during the first year after AMI decreased from 7.1% to 4.7% in patients with diabetes mellitus and from 4.2% to 3.7% in patients without diabetes mellitus. Risk reduction was significantly larger in the diabetic subgroup. Reperfusion therapy, acetylsalicylic acid, P2Y12 inhibitors, and statins were independently associated with the reduced stroke risk. CONCLUSIONS: Ischemic stroke is a fairly common complication after an AMI in patients with diabetes mellitus, but the risk of stroke has decreased during recent years. The increased use of evidence-based therapies contributes importantly to this risk reduction, but there is still room for improvement.
