Sex Differences in Short- and Long-Term Survival after Acute Type A Aortic Dissection.

Background and Objectives: Acute type A aortic dissection (AAD) is a life-threatening disease. No differences between men and women have been made in the treatment of AAD so far and knowledge about sex differences regarding long-term outcomes is limited. Materials and Methods: Between 01/2004 and 12/2021, 874 patients were operated on for AAD, including 313 (35.8%) women and 561 (64.2%) men. Clinical and surgical records, including long-term follow-up information, were obtained and analyzed retrospectively. To account for differences in the outcome determined by different preoperative life expectancies, a subgroup analysis for a set of patients matched according to their remaining life expectancy was performed. Results: At the time of AAD, women were older than men (69.1 ± 13.0 vs. 61.8 ± 13.3 years, p < 0.001) and had a shorter remaining statistical life expectancy (18.6 ± 10.8 vs. 21.4 ± 10.4 years, p < 0.001). Significantly more DeBakey type II AAD was found in women (37.1% vs. 25.7%, p < 0.001). Comorbidities and preoperative status at the time of presentation were similar in women and men. More hemiarch procedures (63.3% vs. 52.0%, p < 0.001) and less arch replacements (8.6% vs. 16.6%, p < 0.001) were performed in women, resulting in shorter cross-clamp times for women (92 ± 39 vs. 102 ± 49 min, p < 0.001). The in-hospital mortality was similar in women and men (11.5% vs. 12.7%, p = 0.618). Long-term survival was significantly shorter in women compared to men (9.8 [8.1-11.5] vs. 15.1 [11.9-18.4] years, p = 0.011). A matched subgroup analysis revealed that when comparing groups with a similar remaining life expectancy, the long-term survival showed no significant differences between women and men (9.8 [7.9-11.6] vs. 12.4 [10.1-14.7] years, p = 0.487). Conclusions: There are sex differences in AAD, with DeBakey type II dissection being more frequent in women. The seemingly worse long-term outcome can mostly be attributed to the shorter remaining statistical life expectancy at the time of presentation.

Surgery for Infective Endocarditis after Primary Transcatheter Aortic-Valve Replacement-A Retrospective Single-Center Analysis.

Transcatheter aortic-valve replacement (TAVR) is increasingly being used for the treatment of aortic-valve stenosis. Therefore, the total number of patients with an aortic-valve prosthesis is increasing, causing the incidence of prosthetic-valve endocarditis to increase. METHODS: Between March 2016 and July 2019, ten patients underwent surgery due to prosthetic-valve endocarditis after TAVR. They were identified in our institutional database and analyzed. RESULTS: Infective endocarditis was diagnosed 17 ± 16 month after TAVR. Mean age was 79 ± 4.4 years. Microbiological detection showed 6/10 positive blood cultures for enterococcus faecalis. Median EuroScore II was 24.64%. The mean size of the surgically replaced aortic prosthesis was 23.6 ± 1.3 and that of the TAVR was 28.4 ± 2.3 mm. The surgically implanted aortic valves had a mean gradient of 8.5 ± 2.2 mmHg. One patient died in hospital due to septic multiorgan failure. After discharge, all patients survived with a mean follow-up of 9 ± 8 month. CONCLUSIONS: With a rising number of patients after TAVR, prosthetic-valve endocarditis will increasingly occur in patients who were previously considered high or intermediate risk. Our results show that patients with TAVR infective endocarditis can be operated on with good results. Surgical therapy should not be withheld from TAVR patients with infective endocarditis.

[What female surgeons wish for!] / Was Chirurginnen sich wünschen!

BACKGROUND: Surgical specialties have a recruitment problem. A magnification of the problem is often seen in the "feminization" of medicine but the causes are multifactorial. Female physicians of the association "Die Chirurginnen e. V." want to raise enthusiasm for their profession and strengthen the affinity for a surgical specialty by increasing the visibility and networking of female surgeons. The aim of this article is to present the results of a survey among female surgeons and to discuss them in the focus of the current shortage of personnel. METHODOLOGY: An anonymized online survey was conducted internally within the association ("Die Chirurginnen e. V.") in October 2022. The survey contained a total of 57 questions and was divided into 7 sections (demographic data, questions about wishes in professional life, private life, social life, towards professional associations, politics and the association). Descriptive statistics were used for the analysis. RESULTS: A total of 358 female surgeons participated in the survey. This represented a response rate of 25.5% of association members (as of October 2022: n = 1406). The mean age was 39.25 years (±8.06 years; range 25-65 years), 37% (n = 133) were in the specialty of orthopedic and trauma surgery and 26% (n = 93) were in the specialty of visceral surgery. The remainder were distributed across a variety of different surgical specialties. The desire for change was preferentially in the area of continuing surgical education, the implementation of working time models, and the organization of the personal workday (operating room time, administrative tasks, time for patients, bureaucracy). DISCUSSION: Motivated and dedicated surgeons are needed to counteract the already existing and increasingly severe shortage of manpower. In recent decades, the proportion of female students and physicians has been increasing, so the needs for recruitment must be increasingly considered. The disparity between men and women at the management level must be gradually resolved. In addition, alternative working models for both genders need to be established in daily practice. By providing a good compatibility of family/private life and career, surgery can remain an attractive profession for future generations.

Lactococcus garvieae Endocarditis in a Prosthetic Aortic Valve: A Case Report and Literature Review.

BACKGROUND: Lactococcus garvieae (LG) is a gram-positive coccus known to be a major pathogen in aqua farming, which is responsible for severe outbreaks. Its incidence in humans is extremely rare. Prior to 1985, all bacteria in the genus Lactococcus were included in the Streptococcus genus. The first human infection was documented in 1991, and since then, the relevance and clinical significance in humans has increased. CASE DESCRIPTION: We present the clinical course of an LG endocarditis in a 78-year-old man who had a history of exertional dyspnea. The patient's blood tests showed increased inflammation values, and a transesophageal ultrasound (TEE) showed a stenosis of the prosthetic aortic valve. Blood cultures were positive for LG, leading to a diagnosis of infective endocarditis. After 6 weeks of intravenous antibiotics and a prosthetic aortic valve replacement, the patient made a good recovery. REVIEW OF THE LITERATURE: After the first documented case in 1991 to 2018, 25 cases of LG endocarditis have been described in PubMed and MEDLINE. We reviewed all reported cases of LG endocarditis, commenting on predisposing risk factors, the course and outcome of the disease. CONCLUSION: LG endocarditis is a rare disease. Consumption of raw fish, abnormalities of the digestive tract, immune deficiency, and underlying cardiac conditions appear to be risk factors for an infective endocarditis due to LG. Improved determination techniques are likely to lead to a better and faster identification of the bacterium. This identification allows a faster and individualized therapy, which in turn affects the outcome.
