RESUMO
PURPOSE: We sought to assess survival outcomes of patients with de novo metastatic breast cancer (dnMBC) who did not receive treatment irrespective of the reason. METHODS: Adults with dnMBC were selected from the NCDB (2010-2016) and stratified based on receipt of treatment (treated = received at least one treatment and untreated = received no treatments). Overall survival (OS) was estimated using the Kaplan-Meier method, and groups were compared. Cox proportional hazards models were used to identify factors associated with OS. RESULTS: Of the 53,240 patients with dnMBC, 92.1% received at least one treatment (treated), and 7.9% had no documented treatments, irrespective of the reason (untreated). Untreated patients were more likely to be older (median 68 y vs 61 y, p < 0.001), have higher comorbidity scores (p < 0.001), have triple-negative disease (17.8% vs 12.6%), and a higher disease burden (≥ 2 metastatic sites: 38.2% untreated vs 29.2% treated, p < 0.001). The median unadjusted OS in the untreated subgroup was 2.5 mo versus 36.4 mo in the treated subgroup (p < 0.001). After adjustment, variables associated with a worse OS in the untreated cohort included older age, higher comorbidity scores, higher tumor grade, and triple-negative (vs HR + /HER2-) subtype (all p < 0.05), while the number of metastatic sites was not associated with survival. CONCLUSIONS: Patients with dnMBC who do not receive treatment are more likely to be older, present with comorbid conditions, and have clinically aggressive disease. Similar to those who do receive treatment, survival in an untreated population is associated with select patient and disease characteristics. However, the prognosis for untreated dnMBC is dismal.

BACKGROUND AND OBJECTIVES: Sociodemographic factors have been shown to impact surgical outcomes. However, the effects of these factors on patients undergoing cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) are not well known. This study aims to evaluate the impact of sociodemographic factors on patients undergoing CRS/HIPEC. METHODS: Adult patients at a tertiary center who underwent CRS/HIPEC were evaluated. Perioperative variables were collected and analyzed. A national database was also used to evaluate patients undergoing CRS/HIPEC. RESULTS: There were 90 patients who underwent CRS/HIPEC (32% non-White). There was no statistically significant difference in postoperative complications, length of stay, or discharge disposition based upon race (white vs. non-White patients), socioeconomic status (SES), or insurance type. Nationally, we found that Black and Hispanic patients were less likely to undergo CRS/HIPEC than Non-Hispanic white patients (Black: odds ratio [OR]: 0.60, [confidence interval {CI}: 0.39-0.94]; Hispanic: OR: 0.52, [CI: 0.28-0.98]). However, there were no significant differences in postoperative complications based upon race/ethnicity. CONCLUSION: Sociodemographic factors including race, SES, and insurance status did not impact postoperative outcomes in patients undergoing CRS/HIPEC at our single institution. On a national level, Black and Hispanic patients underwent CRS/HIPEC at lower rates compared to white patients.

The Arctic has warmed significantly since the early 1980s and much of this warming can be attributed to the surface albedo feedback. In this study, satellite observations reveal a 1.25 to 1.51% per decade absolute reduction in the Arctic mean surface albedo in spring and summer during 1982 to 2014. Results from a global model and reanalysis data are used to unravel the causes of this albedo reduction. We find that reductions of terrestrial snow cover, snow cover fraction over sea ice, and sea ice extent appear to contribute equally to the Arctic albedo decline. We show that the decrease in snow cover fraction is primarily driven by the increase in surface air temperature, followed by declining snowfall. Although the total precipitation has increased as the Arctic warms, Arctic snowfall is reduced substantially in all analyzed data sets. Light-absorbing soot in snow has been decreasing in past decades over the Arctic, indicating that soot heating has not been the driver of changes in the Arctic snow cover, ice cover, and surface albedo since the 1980s.
RESUMO
BACKGROUND AND AIMS: Although a risk-adjusted approach to preventing postoperative nausea and vomiting (PONV) is generally recommended, the successful implementation of such practice without mandated protocols remains elusive. To date, such a strategy has never been adapted to curb high baseline rates of prophylaxis. MATERIAL AND METHODS: We conducted an observational study on a cohort of patients undergoing elective surgery before and after the implementation of a quality improvement initiative including a risk-stratified approach to prevent PONV. The primary outcome was the number of prophylactic interventions administered. Secondary outcome included the repetition of ineffective medications and the need for rescue medication in the post-anesthesia care unit (PACU). RESULTS: A total of 636 patients were included; 325 patients during the control period and 311 after the intervention. The educational program failed to reduce the amount of prophylactic antiemetics administered (2.0 vs. 2.6, P < 0.001) and the repeat administration of ineffective medications for rescue (16% vs. 20%, P = 0.15). More patients in the intervention group required rescue medication compared to the control group (16.9% vs. 9.7%; P = 0.04). CONCLUSION: Implementation of best practices to combat PONV remains elusive. Our results indicate that difficulties in changing provider behavior also apply to institutions with high prophylactic antiemetic administration rates.
RESUMO
BACKGROUND: Nipple sparing mastectomy (NSM) is increasingly being performed for patients with breast cancer. However, optimal postoperative surveillance has not been defined. METHODS: A prospectively maintained database identified patients with in-situ and invasive cancer who underwent NSM between 2007-2021. Clinical data on postoperative breast surveillance and interventions were collected. Patients who had MRI surveillance versus clinical breast exam (CBE) alone were compared with respect to tumor characteristics, recurrence, and survival. RESULTS: A total of 483 NSMs were performed on 399 patients. 255 (63.9%) patients had invasive ductal carcinoma, 31 (7.8%) invasive lobular carcinoma, 92 (23.1%) DCIS, 6 (1.5%) mixed ductal and lobular carcinoma, 9 (2.3%) others, and 6 (1.5%) unknown. Postoperatively, 265 (66.4%) patients were followed with CBE alone and 134 (33.6%) had surveillance MRIs. At a median follow-up of 33 months, 20 patients (5.0%) developed in-breast recurrence, 6 patients had (1.5%) an axillary recurrence, and 28 with (7.0%) distant recurrence. 14 (53.8%) LRR were detected in the CBE group and 12 (46.2%) were detected in the MRI group (P = .16). Overall survival (OS) was 99%, with no difference in OS between patients who had CBE alone versus MRI (P = .46). MRI was associated with higher biopsy rates compared to CBE alone (15.8% vs. 7.8%, P = .01). CONCLUSIONS: Compared to CBE alone, the use of screening MRI following NSM results in higher rate of biopsy and no difference in overall survival.

RESUMO
Background: Mental fatigue largely influences technical performance in soccer, including offensive and defensive skills. However, these effects on technical performance among the soccer players have not yet been aggregated to be assessed systematically. Objective: The purpose of the review was to evaluate the impact of mental fatigue on soccer players' overall technical skills. Methods: Drawing on Web of Science, PubMed, Scopus, and EBSCOhost (CENTRAL and SPORTDicus), an in-depth search was conducted. PICOS established the eligibility criteria to select the studies as follows: (i) population-healthy soccer players; (ii) intervention-involving any mental-fatigue-prompted protocol; (iii) comparison-control conditions (active or passive without inducing mental fatigue); (iv) outcomes-technical performance (offensive and defensive skill); and (v) study design-randomized controlled trials. Results: A total of eight studies were qualified for inclusion in the systematic literature review. Overall, the results indicate that mental fatigue had significant effects on technical skills, including offensive and defensive skills. Specifically, there were significant effects on errors (ES = 0.977; p < 0.001), number of tackles (ES = -0.739; p = 0.005), and the percentage of successful tackles (ES = -0.628; p = 0.022), while there were no significant effects on the number of passes (ES = 0.240; p = 0.328), the percentage of accurate passing (ES = -0.008; p = 0.985), and the number of successful passes (ES = -0.322; p = 0.217). Conclusion: Overall, a significant effect of mental fatigue on the technical performance (e.g., tackles and errors) of soccer players was detected, while no significant effects on passing skills were detected. Future studies may consider investigating technical performance together with other important results (e.g., decision-making skills or internal load).

Oncoplastic breast surgery (OPS) is gaining in popularity compared with traditional breast conserving surgery due to wider resections and better satisfaction with cosmetic outcomes. This study analyzed OPS versus traditional breast conserving surgery outcomes: wound complications, reoperations for margins or fat necrosis, and ipsilateral recurrence. Methods: This retrospective review compared 191 OPS and traditional breast conserving surgery patients on patient-related factors, primary outcomes, and patient reported outcome measures results. A propensity score method analysis using 1:1 to nearest neighbor was also performed. Results: OPS patients were younger, less likely to be smokers, more likely to be ER+ and PR+, and had larger specimen volumes than did traditional breast conserving surgery patients (P < 0.05). There were also differences in distribution of invasive ductal carcinoma and noninvasive disease (P < 0.05). After the propensity score method, the differences observed between the cohorts disappeared. No differences were observed between groups for wound complication, reoperation for positive margins or fat necrosis, or ipsilateral recurrence. Results of patient reported outcome measures showed greater satisfaction with breast surgery in OPS patients (P < 0.01). Conclusions: We showed that OPS is a noninferior technique that should be discussed with appropriate patients. Operative planning should involve patient preferences in optimizing long-term cosmetic outcomes.
RESUMO
BACKGROUND: Inclusion of pancreaticoduodenectomy has demonstrated higher rates of curative treatment in pancreatic cancer, yet prior research has suggested increased postoperative complications in octogenarians (patients older than 80 years). This study aimed to understand the impact of age on patients undergoing a pancreaticoduodenectomy, focusing on postoperative outcomes and return to intended oncologic treatment. MATERIALS AND METHODS: We conducted a single-institution retrospective cohort study for patients undergoing pancreaticoduodenectomy from 2007 to 2018. Collected data included demographics, preoperative comorbidities, and postoperative data (length of stay, 30-day mortality, 1-year mortality, infection, discharge location). Data were separated into 2 cohorts: octogenarians (≥ 80 years) and nonoctogenarians (< 80). χ2 and independent-sample t tests were used for analysis. RESULTS: A total of 649 patients underwent pancreaticoduodenectomy from 2007 to 2018; 63 (9.7%) were octogenarians. No differences were found in infectious complications (P = .607), 30-day mortality (P = .363), or 1-year mortality (P = .895). Octogenarians had a longer length of stay (P = .003) and were more likely to be discharged to skilled nursing facilities (P < .001). There was no significant difference in neoadjuvant chemotherapy administration, although octogenarians were less likely to receive adjuvant chemotherapy (P = .048) and declined adjuvant therapy at a higher rate (P = .003). CONCLUSION: Performing a pancreaticoduodenectomy in octogenarians can be safe and effective in a properly selected cohort. Although postoperative morbidity and mortality are similar to younger patients, elderly patients are more likely to be discharged to nursing facilities and less likely to receive adjuvant chemotherapy. This study suggests that age alone should not be a discriminating factor when discussing surgical therapy for pancreatic cancer treatment in octogenarians.
RESUMO
INTRODUCTION: Breast cancer is the second most common cause of cancer death in females, and 30% of these patients are over the age of 70 years. Studies have shown deviation from the standard treatment paradigms in the elderly, especially in regard to radiation treatment. METHODS: We performed a retrospective chart review on 118 patients over the age of 70 years diagnosed with breast cancer and pathologically proven axillary disease over an 8-year period at an urban academic hospital to examine which patient factors influenced radiotherapy. RESULTS: Increasing patient age was associated with a decrease in the probability of receiving radiotherapy, while HER2-negative patients were more likely to receive radiation. Neither race, number of coexisting medical conditions, or insurance status showed any influence on radiation treatment. CONCLUSION: Patient age has a significant influence if elderly patients with axillary disease receive radiotherapy. Further investigation and validation are needed to understand why chronological age rather than biological age influences treatment modalities.
RESUMO
BACKGROUND: Textbook oncologic outcome has been described in an effort to improve upon traditional outcomes defining care after pancreaticoduodenectomy for adenocarcinoma. We sought to examine whether minimally invasive pancreaticoduodenectomy increased the likelihood of an optimal textbook oncologic outcome. METHODS: Patients undergoing open pancreaticoduodenectomy or minimally invasive pancreaticoduodenectomy between 2010 and 2015 were identified in the National Cancer Database. Textbook oncologic outcome was defined as R0 resection with American Joint Committee on Cancer compliant lymphadenectomy, no prolonged duration of stay, no 30-day readmission/mortality, and receipt of adjuvant chemotherapy. Propensity score matching was employed to evaluate adjusted rates of textbook oncologic outcome, in addition to overall survival. RESULTS: Among 12,854 patients who underwent pancreaticoduodenectomy, 48.3% were female, and the median patient age was 66 years; 87.5% underwent open pancreaticoduodenectomy, and 12.5% underwent whether minimally invasive pancreaticoduodenectomy. After propensity score matching, there were no noted differences in the likelihood of R0 resection, adequate lymphadenectomy, nonprolonged duration of stay, no readmission, no 30-day mortality, adjuvant chemotherapy, or textbook oncologic outcome among open pancreaticoduodenectomy versus minimally invasive pancreaticoduodenectomy (P > .05). Textbook oncologic outcome was associated with an improved median overall survival (negative textbook oncologic outcome: 21.3 months vs positive textbook oncologic outcome: 27.6 months, P < .001). CONCLUSION: Although textbook oncologic outcome was associated with a survival advantage, it was only achieved in 1 in 4 patients undergoing pancreaticoduodenectomy for adenocarcinoma. Achievement of textbook oncologic outcome was equivalent among patients who underwent minimally invasive pancreaticoduodenectomy compared with open pancreaticoduodenectomy after propensity score matching.

INTRODUCTION: Angiotensin system inhibitors are associated with improved prognosis in patients with gastrointestinal and hepatobiliary cancers. Data suggest that renin-angiotensin system signaling stimulates the tumor's immune microenvironment to impact overall survival. The goal of this study is to investigate the role of angiotensin system inhibitor use on the overall survival and disease-free survival of esophageal cancer patients. METHODS: Retrospective review of esophagectomy patients with esophageal adenocarcinoma and squamous cell cancer at a single institution tertiary care center from 2007 to 2018 was performed. Outcomes include overall survival and disease-free survival. Patient characteristics were compared with t test and χ2 test. Survival was analyzed with Kaplan-Meier and Cox proportional-hazards regression. RESULTS: One hundred seventy-one patients were identified and 123 underwent esophagectomy for cancer. No significant differences in patient demographics were found between angiotensin system inhibitor users and non-angiotensin system inhibitor users except for the rates of hypertension (40% vs 94%, Pâ¯<â¯.01) and diabetes (16% vs 47%, Pâ¯<â¯.01). Distributions of tumor neoadjuvant therapy, adjuvant therapy, pathology, staging, margins, and surgical approach were similar. Postoperatively, there was no difference in major adverse cardiovascular events or infection rates. This study did not find any differences in overall survival and disease-free survival between angiotensin system inhibitor users and non-angiotensin system inhibitor users. CONCLUSION: Angiotensin system inhibitors have been shown to improve survival and decrease relative risk for several types of cancers; however, our data do not support the same effect on esophageal cancer patients undergoing curative intent surgery. Further research is needed to investigate potential nuances in angiotensin system inhibitor dose, chronicity of use, esophageal pathology, and applicability to nonsurgical candidates.
RESUMO
Enhanced recovery after surgery (ERAS) is a multimodal protocol applied towards perioperative patient care. ERAS programs are implemented by a multidisciplinary team centered around the patient, incorporating outpatient clinical staff, preoperative nurses, anesthesiologists, operative nurses, postoperative recovery staff, floor inpatient nurses, dieticians, physical therapists, social workers, and surgeons. Initial studies on perioperative care measures focused on cardiac surgery. Subsequently, the development of the ERAS Study Group in 2001 focused on colorectal surgery and postoperative outcome measures. Today, ERAS protocols have been implemented across many surgical subspecialties including: bariatric, breast, plastic, cardiac, colorectal, esophageal, head and neck, hepatic, gynecologic, neurosurgical, orthopedic, pancreatic, thoracic, and urologic surgery. The goal of ERAS programs is to promote rapid recovery as quantified by decreasing the length of hospital stay, complications, and cost of specific surgical interventions. In the setting of the opioid crisis in America, there is also an increasing focus on minimizing perioperative narcotic use. The purpose of this review is to compare ERAS protocols across surgical subspecialties, focusing on quantified metrics of improvement, and to provide a clear and concise summary of the literature in regards to current ERAS practices and success rates.

BACKGROUND: Patients with gastroenteropancreatic neuroendocrine tumors often present with stage IV disease. Primary tumor resection in these patients remains controversial. Herein, we studied the impact of primary tumor removal, identified variables associated with prolonged survival for each neuroendocrine tumor subtype, and determined factors that influence surgeons to perform primary tumor resection. METHODS: Patients with metastatic gastroenteropancreatic neuroendocrine tumors diagnosed from 2004 to 2014 were identified from the National Cancer Database. Nested Cox proportional hazards and logistic regression models were used to assess variables associated with survival and primary resection. RESULTS: A total of 14,510 patients met inclusion criteria. On multivariable analysis, resection of the primary tumor and grade 1 or 2 tumors was associated with prolonged survival in all subtypes (P < .001). Organ-specific variables associated with prolonged survival in patients undergoing primary tumor resection included the following: low grade for all organs; young age for pancreatic, small intestinal, colonic, and rectal neuroendocrine tumor; tumor size for colonic and rectal neuroendocrine tumor; and tumor location for colonic neuroendocrine tumor. Low tumor grade was found to be significantly associated with removal of the primary tumor across all organs. CONCLUSION: This study is the first suggesting that primary tumor resection is associated with prolonged survival for all gastro-entero-pancreatic NETs. Additional variables related to survival for each NET subtype were identified and might help select patients who benefit from primary tumor removal.

Trends in satellite-derived cloud and surface properties for 1982 to 1999 show that the Arctic has warmed and become cloudier in spring and summer but has cooled and become less cloudy in winter. The increase in spring cloud amount radiatively balances changes in surface temperature and albedo, but during summer, fall, and winter, cloud forcing has tended toward increased cooling. This implies that, if seasonal cloud amounts were not changing, surface warming would be even greater than that observed. Strong correlations with the Arctic Oscillation indicate that the rise in surface temperature and changes in cloud amount are related to large-scale circulation rather than to local processes.
