ABSTRACT

Background:Men with testicular cancer receiving platinum-based chemotherapy have an increased risk of thromboembolic events, with incidence rates between 8-24%. A recent trial evaluating the effect of high-intensity interval training (HIIT) prematurely closed as three out of nine participants (33%) in the intervention group developed a thromboembolic event. The purpose of this retrospective cohort study was: 1) (primary) to evaluate the incidence of thromboembolic events in men receiving chemotherapy for testicular cancer who had participated in HIIT during a 6-week exercise program (Body & Cancer) 2) to describe the feasibility of this program.Material and methods: Forty men who had participated in at least one HIIT session from February 2007 to February 2020 were included. Electronic medical records were searched for incident thromboembolic events (arterial and venous) during Body & Cancerand up to one-year post-chemotherapy. Attendance, cardiorespiratory fitness (VO2-peak), and upper and lower extremity muscular strength (1 repetition maximum (RM)) were obtained from the Body & Cancerdatabase.Results: One participant developed a thromboembolic event during Body & Cancer. No participants developed a thromboembolic event in the follow-up period. In all, data represent 160 HIIT sessions with a median attendance of eight sessions [range 1-19]. Statistically significant increases in upper and lower extremity strength were observed (8.6 (4.2 to 13.0) and 26.0 (14.9 to 37.0) kg, respectively). No significant increase in cardiorespiratory fitness was found (0.14 (-0.03 to 0.31) l/min).Conclusion: While conclusions on the safety of HIIT cannot be drawn, data from the present study do not support previous findings cautioning avoidance of HIIT due to a possible added risk of thromboembolic events in men receiving platinum-based chemotherapy for testicular cancer. Considering the potential for positive effects on cardiovascular outcomes associated with HIIT, future studies with robust design should be performed in this population to confirm these observations.

Clinical presentations of acute pulmonary embolism: A retrospective cohort study

Medicine (Baltimore). 2023 Jul 14;102(28):e34224. doi: 10.1097/MD.0000000000034224.

ABSTRACT

We aimed to investigate whether the unusual clinical presentation of pulmonary embolism (PE) varies by the type of provocation. In this retrospective cohort study, we examined the electronic health records (EHR) records of all patients diagnosed with PE (upon presentation or during hospitalization) presented to our tertiary hospital during 2014 to 2019. Inclusion criteria were the diagnosis of acute PE and age above 18 years. Excluded were all patients to whom complete EHR were not available. The primary outcome was the main presenting symptom, categorized by a multidisciplinary consensus expert committee as either typical or atypical of PE. Comorbidities, vital signs, medications and laboratory results on presentations were recorded. 591 patients were included in the final analysis. Dyspnea was significantly less common and hemoptysis and chest pain more common in the unprovoked PE group (35%, 5%, and 25%, respectively) compared with nonmalignant (42.6%, 0%, and 16.3%) and malignancy-associated (47.7%, 0.9%, and 8.2%) PE (Pv = 0.02, 0.002 and 0.001, respectively). No recorded symptoms were the third most common presentation overall, accounting for a significantly (Pv < 0.001) higher proportion of PE patients with malignancy (19%) whereas atypical presentation was the hallmark of patients with nonmalignant provokation (19.7%) (Pv = 0.005). Accounting for multiple potential confounders, the risk of atypical or asymptomatic presentation was higher with lower heart rates (RR = 0.974 95%C.I. [0.957-0.990]) and higher pulse oximetry saturation (RR = 1.114 95%CI [1.034-1.201]). The clinical presentation of PE varies with different types of provoking factors, with atypical presentation most common in nonmalignant provocation and asymptomatic presentation most prevalent in patients with underlying malignancy. Further studies are needed to determine the effect of said variance on long term clinical outcomes.

The impact of body mass index on oncoplastic breast surgery: A multicenter analysis

J Surg Oncol. 2023 Jul 13. doi: 10.1002/jso.27397. Online ahead of print.

ABSTRACT

BACKGROUND: Obesity has nearly tripled in the last 50 years. During the last decades, oncoplastic breast surgery has become an important choice in the surgical treatment of breast cancer. An association exists between higher body mass index (BMI) and wound complications for major operations, but there is scarce literature on oncoplastic surgery. Hence, our aim was to compare the complication rates among patients who underwent oncoplastic surgery, stratified by BMI.

METHODS: Patient data were analyzed from the National Surgical Quality Improvement Program database (NSQIP) for oncoplastic breast procedures (2005-2020). Patients were stratified according to World Health Organization obesity classifications. Multivariate logistic regression was performed to assess risk factors for complications (overall, operative, and wound-related).

RESULTS: From a total of 6887 patients who underwent oncoplastic surgery, 4229 patients were nonobese, 1380 had Class 1 obesity (BMI: 30 to <352 ), 737 Class 2 obesity (BMI: 35 to <402 ), and 541 Class 3 obesity (BMI: ≥ 40 kg/m2 ). Greater operative time was found according to higher BMI (p < 0.001). Multivariate analysis adjusted for baseline characteristics showed that patients with obesity Class 2 (odds ratio [OR] = 1.51, 95% confidence interval [CI]: 1.03-2.23, p = 0.037) and 3 (OR = 1.87, 95% CI 1.24-2.83, p = 0.003) had increased risk of overall and wound complications compared with Nonobese patients. Comparing obese with nonobese patients, there were no differences in rates of deep SSI, organ/space SSI, pneumonia, reintubation, pulmonary embolism, deep vein thrombosis, urinary tract infection, stroke, bleeding, postoperative sepsis, length of stay, and readmission.

CONCLUSIONS: Oncoplastic surgery is a safe procedure for most patients. However, caution should be exercised when performing oncoplastic surgery for patients with Class 2 or 3 obesity (BMI ≥ 35 kg/m2 ), given there was a higher rate of overall and wound-specific complications, compared with patients who were not obese or had Class 1 obesity.

Markers of right ventricular dysfunction predict 30-day adverse prognosis of pulmonary embolism on pulmonary computed tomographic angiography

Medicine (Baltimore). 2023 Jul 14;102(28):e34304. doi: 10.1097/MD.0000000000034304.

ABSTRACT

To investigate the value of parameters of the pulmonary artery and right ventricular function in predicting the 30-day poor prognosis of patients with acute pulmonary embolism (APE). The heart rate, respiratory rate, systolic blood pressure, Wells score for APE, history of recent operation or immobilization, history of cancer, respiratory failure, smoking were significantly (P < .05) different among the control, good prognosis, and poor prognosis groups. The maximal short diameter of the right and left ventricle (RVD/LVD) ratio (P < .001) and left pulmonary artery (LPA) (P = .01) were significantly different between the good and poor prognosis groups. Systolic blood pressure (odds ratio [OR]: 0.98, P = .045) and the RVD/LVD ratio (OR: 12.57, P = .02) were significant independent risk factors for poor prognosis. The risk for poor prognosis significantly increased when the RVD/LVD ratio was >1.11 (cutoff value) with the area under the curve (AUC) of 0.71 (95% confidence interval [CI]: 0.61-0.80, P < .001). LPA (OR: 9.12, P = .01) and RVD/LVD (OR: 4.62, P = .012) were the significant independent risk factors for poor prognosis in the central pulmonary embolism. The LPA of 2.1 cm had the highest predictive value for poor prognosis in the central APE (AUC: 0.68; sensitivity 84.6%; specificity 53.1%). The RVD/LVD ratio and systolic blood pressure are significant risk factors for short-term prognosis in patients with APE. When the LPA is >2.1 cm in the central APE or the RVD/LVD is >1.11, the risk of poor prognosis increases, which can be used as important indicators for predicting the prognosis of patients with APE. Two hundred forty-three APE patients and 61 patients without APE who underwent computed tomographic pulmonary angiography (CTPA) were retrospectively enrolled as the experimental and the control group, respectively. APE patients who were followed up at the 30-day time point were divided into the good prognosis (n = 195) and poor prognosis group (n = 32). The main pulmonary artery (MPA) to the aorta (AO) ratio, maximal diameter of the LPA and right pulmonary artery (RPA), ratio of the RVD/LVD and the height and volume of the pulmonary artery (PAh and PAV, respectively) were analyzed after indexing to the body surface area.
