Smoking is a known risk factor for postoperative mortality and morbidity. However, the significance of cumulative smoking dose in preoperative risk assessment has not been established. We examined the influence of preoperative cumulative smoking dose on surgical outcomes after lobectomy for primary lung cancer.

A total of 80,989 patients with primary lung cancer undergoing lobectomy from 2014 to 2016 were enrolled. Preoperative cumulative smoking dose was categorized by pack-years (PY) nonsmokers, PY= 0; light smokers, 0 < PY < 10; moderate smokers, 10 ≤ PY < 30; and heavy smokers, 30 ≤ PY. The risk of short-term outcomes was assessed according to PY by multivariable analysis adjusted for other covariates.

Postoperative 30-day mortality, as well as pulmonary, cardiovascular, and infectious complications, increased with preoperative PY. Multivariable analysis revealed that the odds ratios (ORs) for postoperative mortality compared with nonsmokers were 1.76 for light smokers (P= .044), 1.60 for moderate smokers (P= .026), and 1.73 for heavy smokers (P= .003). The ORs for pulmonary complications compared with nonsmokers were 1.20 for light smokers (P= .022), 1.40 for moderate smokers (P < .001), and 1.72 for heavy smokers (P < .001). Heavy smokers had a significantly increased risk of postoperative cardiovascular (OR, 1.26; P= .002) and infectious (OR, 1.39; P= .007) complications compared with nonsmokers.

The risk of mortality and morbidity after lung resection could be predicted according to preoperative cumulative smoking dose. These findings contribute to the development of strategies in perioperative management of lung resection patients.

Appropriate conduit selection for right ventricle (RV)-to-pulmonary artery (PA) connection has been extensively studied, with older implantation age, pulmonary (vs aortic) homografts, and true sizing associated with increased longevity. Notably, patients with PA arborization abnormalities (ie, major aortopulmonary collateral arteries [MAPCAs]) are reported to require earlier and more frequent conduit interventions. We aim to understand the behavior of large-diameter aortic homografts in patients with MAPCAs, which are programmatically utilized at our institution.

This is a single-center retrospective cohort study including all children less than 12 years of age who underwent RV-PA connection using an aortic homograft greater than or equal to 16 mm diameter between 2002 and 2019, with a primary outcome of freedom from any RV-PA reintervention and a secondary outcome of freedom from surgical reintervention. Patients were grouped by absolute and indexed conduit sizes for further analysis.

A total of 336 conduits were followed for a median of 3.0 years; transcatheter (n= 30) or surgical (n= 35) reintervention was performed on 64 conduits. Estimated freedom from reintervention and surgical replacement was 84% and 90% at 5 years. Younger age and smaller absolute conduit size were associated with earlier reintervention, but conduit Z-score (median 3.5) was not associated with outcome.

The programmatic use of oversized aortic homograft RV-PA conduits in the surgical repair of MAPCAs provides a focused experience that demonstrates similar longevity to reported best alternatives. Secondarily, conduit oversizing may improve durability and enables an increased likelihood of nonoperative reintervention.

Integrated thoracic surgery (I-6) programs have become popular over traditional general surgery (GS) pathways since their inception in 2007. Chitosan oligosaccharide NF-κB inhibitor However the effect of I-6 programs on GS resident training remains unknown. The purpose of this study was to evaluate the effect of I-6 programs on the thoracic operative experience of co-located GS residents.

Thoracic surgery cases recorded by residents in GS programs co-located with I-6 programs until 2019 were analyzed. Cases were reviewed 5 years before (TSR-5) through 5 years after (TSR-5) the matriculation of the first thoracic resident in the co-located I-6 program. To contextualize the overall trends in the field Accreditation Council for Graduate Medical Education GS resident case logs from 1990 to 2018 were analyzed and total thoracic surgery cases recorded. Statistical analysis was performed with linear regression.

Residents in 19 GS programs with co-located I-6 programs showed an increase in total thoracic cases from 3710 to 4451 (Δ/year of+85.05 cases a year; P= .03) balanced by an increase in GS residents from 107 to 126 (Δ/year of+1.45; P= .01) with no significant overall change in the median thoracic operative case volume (31.00 at both thoracic residency before and after 5 years). Nationally from 1990 to 2018 there was no change in the total thoracic operative experience for GS graduates.

The introduction of I-6 programs did not negatively impact thoracic operative experience for residents in co-located GS programs. Adequate training of both I-6 and GS residents at the same institution is feasible.

Although intentionally added chemicals (e.g., food additives) and food contact materials (e.g., packaging, pesticides) have been assessed for safety to some degree, the full extent to which they can affect health and reproduction has not been reported. The aim of this study was to determine the in vitro and in vivo effects of food additives on the male rat brain and sperm/testes, particularly through oxidative stress. Results from our in vitro study demonstrated that the administration of the common food additive, stevioside, a major component of the common sweetener stevia, as well as the preservatives, diphenyl and orthophenyl phenol (OPP), induced reactive oxygen species (ROS) production in sperm, and led to sperm dysfunction. These effects were inhibited by the addition of the antioxidant α-tocopherol. Moreover, OPP treatment (1/10,000 of no observed adverse effect) induced ROS production in sperm and lipid peroxidation in the epididymis and hippocampus after two weeks in vivo.
