 When video-assisted thoracoscopic segmentectomy with curative intent was performed with sufficient surgical margins, the location of small NSCLC did not affect recurrence risk and prognosis. Video-assisted thoracoscopic segmentectomy for small NSCLC is acceptable, regardless of the tumor location.

 Many authors have investigated the possible adverse effects among patients who underwent elective surgery on Friday when compared with patients operated earlier in the week. Nonetheless, the weekday effect is still a matter of debate. This study aimed at investigating the postoperative morbidity rates after lung cancer surgery and their relationship with the weekday the surgery took place.

 We retrospectively reviewed the clinical records of patients who underwent elective thoracotomic lobectomies for lung cancer. Categorical data were analyzed using the chi-square test or Fisher's exact test. Association between predictors and binary outcomes while considering the weekday stratification was determined with Cochran-Mantel-Haenszel statistics. To characterize the typical Friday patient, a multiple logistic regression analysis was performed.

 A total of 817 patients (2015-2019) were identified. Complication rates divided by day of surgery were 164 (20.07%) for patients operated on Mondays, 182 (22.27%) on Tuesdays, 205 (25.09%) on Wednesdays, 172 (21.05%) on Thursdays, and 94 (11.51%) on Fridays. Crude morbidity rates by weekday were Monday 21.53%, Tuesday 20.51%, Wednesday 27.70%, Thursday 20.0%, and Friday 10.26%. No overall association between day of surgery and overall morbidity was found (ρ = 0.095). Median hospital length of stay was 5 days (range 2-45 days), and there were no statistically significant differences between days. The Cochran-Mantel-Haenszel statistics showed no association between morbidity and the weekday.

 In patients undergoing elective lobectomies for lung cancer, the weekday of surgery was not statistically significantly associated with an increase in the risk of postoperative morbidity.

 Pediatric sternal wound complications (SWCs) include sterile wound dehiscence (SWD) and superficial/deep sternal wound infections (SSWI/DSWI), and are generally managed by repetitive debridement and surgical wound approximation. Here, we report a novel nonsurgical management strategy of pediatric sternotomy wound complications, using serial noninvasive wound approximation technique combined with single-use negative pressure wound therapy (PICO) device.

 Nine children with SWCs were managed by serial approximation with adhesive skin tapes and serial PICO device application. Thorough surgical debridement or surgical approximations were not performed.

 Three patients were clinically diagnosed as SWD, two patients as SSWI, and four patients as DSWI. None of the wounds demonstrated apparent mediastinitis or bone destructions. VS-6063 in vivo PICO device was applied at 16.1 days (range 6-26 days) postoperatively, together with serial wound approximation by skin tapes. The average duration of PICO use was 16.9 days (range 11-29 days) and the wound approximation was achieved in all patients. None of the patients underwent aggressive surgical debridement or invasive surgical approximation by sutures.

 We report our successful management of selected pediatric SWCs, using serial noninvasive wound approximation technique combined with PICO device.

 Prosthetic vascular grafts placed surgically or via endovascular techniques can be subject to the risk of life-threatening graft infections. The Omniflow II vascular prosthesis is a biosynthetic graft that was reported to have favorable properties in resisting infections.

 We retrospectively reviewed our 3 years' experience of using the Omniflow II prostheses for aortoiliac reconstructions in patients considered to carry a substantial risk of subsequent prosthetic graft infections (prevention group) as well as in patients with actively infected prosthetic vascular grafts (treatment group).

 Aorto-bi-iliac (

 = 4) and aortobifemoral (

 = 12) vascular reconstructions were performed using bifurcated Omniflow II prostheses in nine patients in the prevention group and seven patients in the treatment group. During mean follow-up of 28.6 ± 17.2 months, there was one case of graft infection (6.3%) and graft thrombosis (6.3%) with subsequent successful thrombectomy. Early and late surgical revisions were required in eight (50%) and two (12.6%) patients, respectively. All graft prostheses were patent at last follow-up.

 Using bifurcated Omniflow II vascular prostheses in patients with or at a high risk of vascular graft infection is advisable, and is associated with acceptable reinfection and patency rates.

 Mitral valved stents tend to migrate or to develop paravalvular leakage due to high-left ventricular pressure in this cavity. Thus, this study describes a newly developed mitral valved stent anchoring technology.

 Based on an existing mitral valved stent, four anchoring units with curved surgical needles were designed and fabricated using three-dimensional (3D) software and print technology. Mitral nitinol stents assembled with four anchoring units were successively fixed on 10 porcine annuli. Mechanical tests were performed with a tensile force test system and recorded the tension forces of the 10 nitinol stents on the annulus.

 The average maximum force was 28.3 ± 5.21 N, the lowest was 21.7 N, and the highest was 38.6 N until the stent lost contact with the annulus; for the break force (zero movement of stent from annulus), the average value was 18.5 ± 6.7 N with a maximum value of 26.9 N and a minimum value of 6.07 N. It was additionally observed that the puncture needles of the anchoring units passed into the mitral annulus in all 10 hearts and further penetrated the myocardium in only one additional heart.
