Laparoscopy is superior to open surgery for elective colectomy, but its role in emergency colectomy remains unclear. Previous studies were small and limited by confounding because surgeons may have ...selected lower-risk patients for laparoscopy. We therefore studied the effect of attempting laparoscopy for emergency colectomies while adjusting for confounding using multiple techniques in a large, nationwide registry.
Using National Surgical Quality Improvement Program data, we identified emergency colectomy cases from 2014 to 2018. We first compared outcomes between patients who underwent laparoscopic versus open surgery, while adjusting for baseline variables using both propensity scores and regression. Next, we performed a negative control exposure analysis. By assuming that the group that converted to open did not benefit from the attempt at laparoscopy, we used the observed benefit to bound the effect of unmeasured confounding.
Of 21,453 patients meeting criteria, 3,867 underwent laparoscopy, of which 1,375 converted to open. In both inverse probability of treatment weighting and regression analyses, attempting laparoscopy was associated with improved 30-day mortality, overall morbidity, anastomotic leak, surgical site infection, postoperative septic shock, and length of hospital stay compared with open surgery. These effects were consistent with the lower bounds computed from the converted group.
Laparoscopic surgery for colorectal emergencies appears to improve outcomes compared with open surgery. The benefit is observed even after adjusting for both measured and unmeasured confounding using multiple statistical approaches, thus suggesting a benefit not attributable to patient selection.
An epithelioid hemangioma (EH) is a rare benign vascular lesion that is usually seen in superficial small vessels within the dermis and subcutaneous tissue. Intravascular epithelioid hemangiomas of ...large and medium-sized vessels are rare, and only a handful of cases have been reported in the literature. Intravascular epithelioid hemangiomas are biologically benign and best treated by complete surgical excision. On occasion, lesions have been associated with aneurysmal changes in the affected vessel. Local recurrence may occur, and close clinical follow-up is advised. Herein, we report the second case in the literature of an EH originating from the popliteal artery. A 57-year-old male patient presented with a one-month history of knee pain without claudication. Imaging highlighted a right popliteal aneurysm, 5x5 cm, with partial distal thrombosis and inadequate outflow. The patient subsequently underwent popliteal artery ligation above and below the aneurysm, reconstructed with a superficial femoral artery (SFA) to distal anterior tibial artery (ATA) reverse saphenous vein bypass graft. Patient recovery was complicated by the development of a 5x5 cm right-sided mid-thigh hematoma, requiring evacuation under anesthesia. A post-one-year arterial duplex of the affected limb demonstrated a recurrent enlarging popliteal aneurysm measuring 5.7x4.8x9.1 cm. The aneurysm was reported to be mostly thrombosed with noted vascularity, but patency of the original bypass was noted. The patient underwent excision of the recurrent aneurysm with subsequent ligation of the feeding arteries. Pathology and histology confirmed the final diagnosis of EH of the popliteal artery. An 18-month follow-up after the excision procedure demonstrated no recurrence of vascular lesion and patency of the original bypass graft.
A bstract Background: Football demands mastery of diverse motor skills, emphasizing intricate micro-movements. Effective warm-up protocols, such as raise, activate, mobilize, and potentiate (RAMP), ...are crucial for injury prevention and performance enhancement. RAMP systematically elevates heart rate, activates muscles, mobilizes joints, and potentiates neuromuscular systems. Its structured approach optimally prepares athletes for intensive training and on-field activities. Aim: This study aims to evaluate the effect of RAMP warm-up on speed, agility, and endurance in male football players. Materials and Methods: Fifty football players meeting specific criteria were chosen, briefed on study procedures, and provided written consent. They were randomly assigned to either a 4-week RAMP warm-up or a traditional warm-up group. Speed, agility, and endurance were assessed before and after the intervention using diverse tests. Result: Statistical tests included paired t tests for intra-group and independent t tests for inter-group comparisons. Intra-group analysis showed notable improvements in the 30-m sprint, agility t test, and Yo-Yo endurance. Between-group analysis indicated significant enhancements in functional performance for the RAMP warm-up group. Specifically, RAMP warm-up was effective in improving speed ( P = 0.001), agility ( P = 0.001), and endurance ( P = 0.002). Conclusion: The study demonstrated that the RAMP warm-up effectively improved the speed, agility, and endurance of football players, highlighting its potential as a valuable addition to training programs.
Geriatric patients with rib fractures are at risk for developing complications and are often admitted to a higher level of care (intensive care units ICUs) based on existing guidelines. Forced vital ...capacity (FVC) has been shown to correlate with outcomes in patients with rib fractures. Complete spirometry may quantify pulmonary capacity, predict outcome, and potentially assist with admission triage decisions.
We prospectively enrolled 86 patients, 60 years or older with three or more isolated rib fractures presenting after injury. After informed consent, patients were assessed with respect to pain (visual analog scale), grip strength, FVC, forced expiratory volume 1 second (FEV1), and negative inspiratory force on hospital days 1, 2, and 3. Outcomes included discharge disposition, length of stay (LOS), pneumonia, intubation, and unplanned ICU admission.
Mean age was 77.4 (SD, 10.2) and 43 (50.0%) were female. Forty-five patients (55.6%) were discharged home, median LOS was 4 days (interquartile range, 3-7). Pneumonias (2), unplanned ICU admissions (3), and intubation (1) were infrequent. Spirometry measures including FVC, FEV1, and grip strength predicted discharge to home and FEV1, and pain level on day 1 moderately correlated with the LOS. Within each subject, FVC, FEV1, and negative inspiratory force did not change for 3 days despite pain at rest and pain after spirometry improving from day 1 to 3 (p = 0.002, p < 0.001 respectively). Change in pain also did not predict outcomes and pain level was not associated with respiratory volumes on any of the 3 days. After adjustment for confounders, FEV1 remained a significant predictor of discharge home (odds ratio, 1.03; 95% confidence interval, 1.01-1.06) and LOS (p = 0.001).
Spirometry measurements early in the hospital stay predict ultimate discharge home, and this may allow immediate or early discharge. The impact of pain control on pulmonary function requires further study.

The COVID-19 pandemic has led to an increase in SARS-CoV-2-test positive potential organ donors. The benefits of life-saving liver transplantation (LT) must be balanced against the potential risk of ...donor-derived viral transmission. Although emerging evidence suggests that the use of COVID-19-positive donor organs may be safe, granular series thoroughly evaluating safety are still needed. Results of 29 consecutive LTs from COVID-19-positive donors at a single center are presented here.
A retrospective cohort study of LT recipients between April 2020 and December 2022 was conducted. Differences between recipients of COVID-19-positive (n = 29 total; 25 index, 4 redo) and COVID-19-negative (n = 472 total; 454 index, 18 redo) deceased donor liver grafts were compared.
COVID-19-positive donors were significantly younger (
= 0.04) and had lower kidney donor profile indices (
= 0.04) than COVID-19-negative donors. Recipients of COVID-19-positive donor grafts were older (
= 0.04) but otherwise similar to recipients of negative donors. Donor SARS-CoV-2 infection status was not associated with a overall survival of recipients (hazard ratio, 1.11; 95% confidence interval, 0.24-5.04;
= 0.89). There were 3 deaths among recipients of liver grafts from COVID-19-positive donors. No death seemed virally mediated because there was no qualitative association with peri-LT antispike antibody titers, post-LT prophylaxis, or SARS-CoV-2 variants.
The utilization of liver grafts from COVID-19-positive donors was not associated with a decreased overall survival of recipients. There was no suggestion of viral transmission from donor to recipient. The results from this large single-center study suggest that COVID-19-positive donors may be used safely to expand the deceased donor pool.
