Additionally, DA induced oxidative stress by increased production of reactive oxygen species accompanied by changes in glutathione, superoxide dismutase, malondialdehyde and protein carbonyl levels. Overall, the obtained results showed adverse genotoxic effects of DA in non-target HPBCs.Snakebite in Mexico is commonly treated with an antivenom which uses Bothrops asper and Crotalus simus venoms as immunogens. Current taxonomic recommendations for the C. simus species complex suggest a novel endemic species from Mexico Crotalus mictlantecuhtli. The aim of this report was to evaluate the immunogenic properties of C. mictlantecuhtli venom and its potential to generate polyclonal antibodies capable of neutralizing other pitviper venoms. We generated an experimental anti-Crotalus mictlantecuhtli serum, using the rabbit model, to test recognition and neutralizing capacity against the homologous venom as well as venoms from C. atrox, C.basiliscus, C. durissus terrificus, C. scutulatus salvini, C. tzabcan and Ophryacus sphenophrys. Pre-incubation neutralization experiments using our experimental serum showed positive results against venoms containing crotoxin, while venoms from two non-neurotoxic pit-vipers were not neutralized. Rescue experiments in mice showed that, when intravenously injected (i.v.), C. mictlantecuhtli venom is not neutralized by a maximum dose of Antivipmyn® and the experimental serum after 5 min of envenomation, albeit mice envenomated intraperitoneally (i.p.) and rescued i.v. with Antivipmyn® survived even at 50 min after envenomation. Our results highlight the importance of using the highly neurotoxic C. mictlantecuhtli venom to increase antivenom effectiveness against Mexican neurotoxic pitvipers.Snakebite envenomation is a global health crisis and is classified as a Category A neglected tropical disease by the World Health Organization (WHO). Procyanidin C1 order Snakebite envenomations account for a significant amount of morbidity and morbidity in tropical and subtropical regions. Recently, publications have illustrated the potential for snake envenomations causing post-traumatic stress disorder (PTSD) in a significant number of patients. Ketamine is on the WHO's list of essential medications and is used for a variety of pharmacologic applications including anesthesia and acute pain management. To date it has not been assessed for pain control in snakebite envenomations. Twelve patients who presented with severe pain secondary to Bitis, Causus, and Atractaspis envenomations were treated with low-dose intravenous ketamine. The patients included 7 males and 5 females with a median age of 37.5 (range 14-64) and a median presentation time of 5.75 h (range 5 min-96 h) after the initial bite occurred. Ten envenomations were pfe, and effective solution for Sub-saharan Africa and other resource-limited settings. Controlled studies need to be done to critically assess our observations.
The role of simulation-based training in coronary artery bypass grafting remains undefined. Barriers to simulator use include clinical and personal obligations, insufficient materials, and lack of mentorship. The purpose of this study was to implement a longitudinal, residency-wide coronary anastomosis simulation curriculum.
A prospective observational study was conducted from 2018 to 2019 at a single academic center. All residents of the Thoracic Surgery training program participated. Each participant was provided a low-fidelity coronary anastomosis simulator, high-quality instruments, and faculty mentor. Formal assessments were held quarterly, and residents were encouraged to practice alone and with their mentor. Baseline and follow-up metrics were compared with simple descriptive statistics.
Seventeen residents and 12 faculty participated in the study. Residents demonstrated increased use of the simulator, with 21% participating in independent practice at baseline and 82% in the fourth quarter (P= .0sment scores, and anastomosis time. Our next step is validating the coronary simulator curriculum by measuring improvement of resident performance in the operating room.
Stereotactic body radiation therapy (SBRT) is increasingly being offered for early stage non-small cell lung cancer (NSCLC). We sought to evaluate long-term survival outcomes after lobectomy and SBRT in patients aged 80 years or more with stage I NSCLC.
The National Cancer Database was queried for patients with clinical stage IA and IB (size 40 mm or smaller) NSCLC who underwent SBRT or lobectomy. Only patients with no comorbidities were selected. Number of lymph nodes (LN) examined was used to stratify lobectomy patients into 0 LN, 1 to 6 LN, and 7 or more LN. Propensity score analysis was used to adjust treatment groups. Kaplan-Meier and multivariate Cox regression analysis were used for survival analysis.
A total of 8964 patients with stage I NSCLC treated with lobectomy were compared with 286 patients who received SBRT. Using propensity matched pairs, lobectomy (7 LN or more) had significantly improved survival as compared with SBRT (median 74 vs 53.2 months, P < .05); however, no survival differences were observed when 0 LN were sampled (median 53.8 vs 52.3 months, P= .88). In multivariate analysis, lobectomy was associated with significantly improved survival (hazard ratio 0.726; 95% confidence interval; 0.580 to 0.910; P= .005). In addition, age, sex, high grade, and tumor size were independent predictors of survival.
Among healthy octogenarians with clinical stage I NSCLC who are good surgical candidates, lobectomy offers better survival than SBRT. Adequate LN dissection allows true nodal staging and opportunity for adjuvant treatment when unsuspected nodal metastases are found.

Non-home hospital disposition is an important patient-centric quality measure, and is increasingly tied to reimbursements. We sought to determine the value of early postoperative functional assessment to predict non-home discharge.
Patients undergoing elective pulmonary lobectomy between May 2017 and December 2018 were identified from The Society of Thoracic Surgery database at a single institution. Early postoperative functional assessment using the Boston University Activity Measure for Post-Acute Care (AM-PAC) basic mobility short form was routinely performed by the inpatient rehabilitation services. The association of baseline patient characteristics and AM-PAC scores with nonhospital discharge was analyzed.
A total of 241 patients (median age 65 years, 59% female) underwent lobectomy. First postoperative functional assessment was performed at a median of 1 day (interquartile range, 1 to 2) after surgery. Median AM-PAC score was 18 (interquartile range, 17 to 19), correlating to a 47% functional impairment in daily activities.
