Objective: To investigate whether ventilatory factors limit exercise in overweight and obese children during a 6-min step test and to compare ventilatory responses during this test with those of healthy weight children. Conclusions: Young people who are overweight/obese are more likely to display expFL during submaximal exercise compared with children of healthy weight . Use of compensatory breathing strategies appeared to enable overweight children to avoid the experience of breathlessness at this intensity of exercise. Design: Cross-sectional, prospective comparative study. Results: Young people who are overweight or obese are more likely to experience expiratory flow limitation (expFL) during submaximal exercise compared with their healthy weight peers [OR 7.2 (1.4, 37.3), P=0.019]. Subjects who had lower lung volumes at rest were even more likely to experience exercise-induced expFLs [OR 8.35 (1.4-49.3)]. Both groups displayed similar breathing strategies during submaximal exercise. Subjects: Twenty-six overweight/obese subjects and 25 healthy weight subjects with no known respiratory illness.Measurements:Various fatness and fat distribution parameters (using air displacement plethysmography and anthropometry), pulmonary function tests, breath-by-breath gas analysis during exercise, perceived exertion.

- Abstract
Aim: Obesity is a well-established risk factor for the development of colorectal cancer. As such, patients undergoing surgery for colorectal cancer have increasingly higher body mass indices (BMIs). The advances in minimally invasive surgical techniques in recent years have helped surgeons circumvent some of the challenges associated with operating in the setting of obesity. While previous studies suggest that laparoscopy improves outcomes compared with open surgery in obese patients, this has never been established at the population level. Therefore, we designed a retrospective database study using the National Inpatient Sample (NIS) with the aim of comparing laparoscopic with open approaches for obese patients undergoing surgery for colorectal cancer., Method: A retrospective analysis of the NIS from 2015 to 2019 was conducted including patients with a BMI of greater than 30 kg/m
2 undergoing surgery for colorectal cancer. The primary outcomes were postoperative in-hospital morbidity and mortality. Secondary outcomes included postoperative system-specific complications, total admission healthcare cost and length of stay (LOS). Multivariable logistic and linear regressions were utilized to compare the two operative approaches., Results: A total of 4742 patients underwent open surgery and 3231 underwent laparoscopic surgery. We observed a significant decrease in overall postoperative morbidity [17.5% vs. 31.4%, adjusted odds ratio (aOR) 0.56, 95% confidence interval (CI) 0.50-0.64; p < 0.001], gastrointestinal morbidity (8.1% vs. 14.5%, aOR 0.59, 95% CI 0.50-0.69; p < 0.001) and genitourinary morbidity (10.1% vs. 18.6%, aOR 0.61, 95% CI 0.52-0.70; p < 0.001) with the use of laparoscopy. Postoperative LOS was 1.7 days shorter (95% CI 1.5-2.0, p < 0.001) and cost of admission was decreased by $9106 (95% CI $4638-$13 573, p < 0.001) with laparoscopy., Conclusion: Laparoscopic surgery for obese patients with colorectal cancer is associated with significantly decreased postoperative morbidity and improved healthcare resource utilization compared with open surgery. Laparoscopic approaches should be relied upon whenever feasible for these patients., (© 2023 The Authors.

- Abstract
The opioid epidemic, impacted from the proliferation of fentanyl, has added impetus to the need to detect fentanyl, sources of fentanyl, and places where fentanyl and drugs adulterated with fentanyl are available. Many darknet marketplaces (DNMs) have rules that ban fentanyl. However, it is unclear how these affect the fentanyl market. Using the AlphaBay DNM as a case study, we conducted mixed methods qualitative research. We scraped and analyzed data from the AlphaBay I2P website using, among other methods, content and social network analysis, to uncover hidden fentanyl networks. Our research highlights the next evolution of darknet marketplaces - the migration of DNMs from Tor to I2P and the methods that can be used identify fentanyl networks, irrespective of where sites are: I2P, Tor, or multihomed on I2P and Tor. Despite its ban in the Global AlphaBay Rules, our research revealed the sale of fentanyl on the AlphaBay DNM. Unlike previous studies, our findings predominantly revealed the covert sale of fentanyl on AlphaBay and predatory vendors selling illicit drugs, which unbeknownst to buyers, contained fentanyl. To a lesser extent, our findings identified the overt sale of fentanyl patches on AlphaBay. Although we examined only one DNM, the prevalence of the covert sale of fentanyl and the presence of predatory vendors underscores the importance of research that decodes the language of vendors who surreptitiously sell fentanyl or drugs adulterated with fentanyl or other illicit substances. The results of our research can inform strategies aimed at disrupting and dismantling DNM fentanyl networks., (© 2023 American Academy of Forensic Sciences.)

- Abstract
Hate crimes generally have severe victim outcomes compared to other crimes, and therefore warrant further investigation. These types of crimes can often happen in neighborhoods where people from various cultures, socioeconomic backgrounds, religions, etc. meet. Understanding how neighborhood tensions impact the level of hate crimes is important in reducing hate crimes and building community. The current study investigates neighborhood level predictors of hate crimes in a borough of New York City (NYC). Using symbolic threat and defended neighborhoods frameworks, we consider how 311 noise complaints and land use rezoning data can be predictors of hate crimes. We use data from the New York City Police Department (NYPD) and NYC Land Use Tax Output. We find that hate crimes are more likely in the neighborhoods where the noise complaints and land use rezoning are higher than the median. The theoretical implications of these findings are discussed below.

- Abstract
Purpose: Dexamethasone is a glucocorticoid that is often administered intraoperatively as prophylaxis for postoperative nausea and vomiting (PONV). Several randomized controlled trials (RCTs) have examined its use in colorectal surgery. This systematic review aims to assess the postoperative impacts of dexamethasone use in colorectal surgery., Methods: MEDLINE, Embase, and CENTRAL were searched from database inception to January 2023. Articles were included if they compared perioperative intravenous dexamethasone to a control group in patients undergoing elective colorectal surgery in terms of postoperative morbidity. The primary outcomes were prolonged postoperative ileus (PPOI) and PONV. Secondary outcomes included postoperative infectious morbidity and return of bowel function. A pair-wise meta-analysis and GRADE assessment of the quality of evidence were performed., Results: After reviewing 3476 relevant citations, seven articles (five RCTs, two retrospective cohorts) met the inclusion criteria. Overall, 1568 patients received perioperative dexamethasone and 1459 patients received a control. Patients receiving perioperative dexamethasone experienced significantly less PPOI based on moderate-quality evidence (three studies, OR 0.46, 95%CI 0.28-0.74, p < 0.01). Time to first flatus was significantly reduced with intravenous dexamethasone. There was no difference between groups in terms of PONV (four studies, OR 0.90, 95%CI 0.64-1.27, p = 0.55), postoperative morbidity (OR 0.93, 95%CI 0.63-1.39, p = 0.74), or rate of postoperative infectious complications (seven studies, OR 0.74, 95%CI 0.55-1.01, p = 0.06)., Conclusion: This review presents moderate-quality evidence that perioperative intravenous dexamethasone may reduce PPOI and enhance the return of bowel function following elective colorectal surgery. There was no significant observed effect on PONV or postoperative infectious complications., (© 2023. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

- Abstract
Background: Over the last decade, use of laparoscopy for the treatment of colon cancer has been variable despite evidence of benefit, possibly reflecting surgeon expertise rather than other factors., Objective: The purpose of this study was to examine the spatial variation in the use of laparoscopy for colon cancer surgery and to determine what factors may influence use., Design: This was a population-based retrospective analysis from April 2008 to March 2015., Settings: All Canadian provinces (excluding Quebec) were included., Patients: The study included all patients ≥18 years of age undergoing elective colectomy for colon cancer., Main Outcome Measures: The primary outcome was laparoscopy use rates. Predictors of use included patient and disease characteristics, year of surgery, rurality, hospital and surgeon volumes, and distance from a colorectal fellowship training center., Results: A total of 34,725 patients were identified, and 42% underwent laparoscopic surgery. Significant spatial variations in laparoscopy use were identified, with 95% of high-use clusters located ≤100 km and 98% of low-use clusters located >100 km from a colorectal fellowship center. There were no high-use clusters located around large academic centers without colorectal fellowships. At the individual level, patients living within 25 km and 26 to 100 km of a fellowship center were 2.6 and 1.6 times more likely to undergo laparoscopic surgery compared with those >100 km away (95% CI, 2.47-2.79, p < 0.00; 95% CI, 1.53-1.71, p < 0.001). Surgeon and hospital volumes were associated with increased rates of laparoscopy use (p < 0.001)., Limitations: Data were obtained from an administrative database, and despite 85% to 95% published validity, they remain subject to misclassification, response, and measurement bias., Conclusions: Significant spatial variations in the use of laparoscopy for colon cancer surgery exist. After adjusting for patient and system factors, proximity to a colorectal fellowship training center remained a strong predictor of laparoscopy use. There remain regional variations in colon cancer treatment, with discrepancies in the surgical care offered to Canadian patients based solely on location.

Los predictores de uso incluyeron las características del paciente y la enfermedad, el año de la cirugía, la ruralidad, los volúmenes de hospitales y cirujanos, y la distancia a un centro de formación de residentes colorectales.RESULTADOS:Se identificaron 34.725 pacientes, 42% fueron sometidos a cirugía laparoscópica. Se identificaron variaciones espaciales significativas en el uso de laparoscopia, con el 95% de los conglomerados de alto uso ubicados a <100 km y el 98% de los conglomerados de bajo uso ubicados a> 100 km, desde un centro de residencia colorectal. No había grupos de alto uso ubicados alrededor de grandes centros académicos sin residentes colorrectales. A nivel individual, los pacientes que vivían dentro de los 25 km y 26-100 km de un centro de residentes tenían 2,6 y 1,6 veces más probabilidades de someterse a una cirugía laparoscópica, respectivamente, en comparación con aquellos a> 100 km de distancia (95% CI 2,47-2,79, p <0,00; IC del 95% 1,53-1,71, p <0,001). Los volúmenes de cirujanos y hospitales se asociaron con mayores tasas de utilización de laparoscopia (p <0,001).LIMITACIONES:Los datos se obtuvieron de una base de datos administrativa y, a pesar de una validez publicada del 85-95%, siguen sujetos a errores de clasificación, respuesta y sesgo de medición.CONCLUSIONES:Existen variaciones espaciales significativas en el uso de la laparoscopia para la cirugía del cáncer de colon. Después de ajustar por factores del paciente y del sistema, la proximidad a un centro de formación de residentes colorectales siguió siendo un fuerte predictor del uso de laparoscopia. Sigue habiendo variaciones regionales en el tratamiento del cáncer de colon, con discrepancias en la atención quirúrgica ofrecida a los pacientes canadienses basadas únicamente en la ubicación.

- Abstract
Purpose: Children born preterm have impaired lung function and altered lung structure. However, there are conflicting reports on how preterm birth impacts aerobic exercise capacity in childhood. We aimed to investigate how neonatal history and a diagnosis of bronchopulmonary dysplasia (BPD) impact the relationship between function and structure of the lung, and aerobic capacity in school-aged children born very preterm., Methods: Preterm children (≤ 32 w completed gestation) aged 9-12 years with (n = 38) and without (n = 35) BPD, and term-born controls (n = 31), underwent spirometry, lung volume measurements, gas transfer capacity, a high-resolution computer tomography (CT) scan of the chest, and an incremental treadmill exercise test., Results: Children born preterm with BPD had an elevated breathing frequency to tidal volume ratio compared to term controls (76% vs 63%, p = 0.002). The majority (88%) of preterm children had structural changes on CT scan. There were no differences in peak V̇O
2 (47.1 vs 47.7 mL/kg/min, p = 0.407) or oxygen uptake efficiency slope when corrected for body weight (67.6 vs 67.3, p = 0.5) between preterm children with BPD and term controls. There were no differences in any other exercise outcomes. The severity of structural lung disease was not associated with exercise outcomes in this preterm population., Conclusion: Children born preterm have impaired lung function, and a high prevalence of structural lung abnormalities. However, abnormal lung function and structure do not appear to impact on the aerobic exercise capacity of preterm children at school age.- Published

- Abstract
Aim: We assessed the feasibility of telehealth spirometry assessments for children with cystic fibrosis (CF) living in a regional setting., Method: Patients with acceptable computer hardware at home were provided with a SpiroUSB (Vyaire) spirometer. Spirometry was performed during 'home admissions' or for ongoing home monitoring in children living outside metropolitan Melbourne. At the end of the session, the family forwarded the data to the Royal Children's Hospital, Melbourne., Results: Twenty-two patients aged 7 to 17 years participated, with spirometry successful in 55 of 59 (93%) attempted sessions according to American Thoracic Society/European Respiratory Society criteria. The median distance between the subject's home and the hospital was 238 km (range 62-537 km) which equated to a travel time saving of 5 hours and 34 min per hospital visit., Conclusion: Home-based telehealth spirometry is feasible in children with CF and can support the CF team during home-based admissions and for ongoing outpatient monitoring., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

- Abstract
Purpose: The uptake of minimally invasive surgery (MIS) for colorectal cancer (CRC) varies between jurisdictions. We aimed to identify the factors associated with the uptake of MIS for early-stage CRC and its oncologic outcomes in the Canadian province of Ontario., Methods: This study includes all patients with CRC in Ontario from 2007 to 2017. A logistic regression analysis was used to identify the predictors of MIS and a flexible parametric survival model to estimate survival rates based on MIS versus open surgery., Results: In total, 14,675 patients with CRC were identified of which 29.5% had MIS resections. The likelihood of undergoing MIS decreased with age, disease stage, and distance to the regional cancer center, and increased with year of diagnosis. The likelihood of mortality for MIS was significantly lower compared to open surgery (p < 0.001). In terms of survival, MIS was most beneficial to older patients with stage II disease, despite their lower likelihood of receiving MIS., Conclusions: Despite the lower uptake of MIS among older patients and patients with stage II disease, these patients had the greatest long-term survival benefit from MIS. This suggests further use of laparoscopy to patient populations that are often excluded., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

- Abstract
Purpose: The widespread use of laparoscopy has brought forth the question of how to manage a macroscopically normal-appearing appendix in cases of clinically suspected appendicitis. This study aimed to determine the current practices of pediatric general surgeons in Canada regarding this matter., Methods: An online survey was created following the American Pediatric Surgical Association (APSA) guidelines and distributed via email to the Canadian Association of Pediatric Surgeons (CAPS) staff surgeons. The questions assessed clinician characteristics, standard practice, and rationale. Results were analyzed using descriptive statistics., Results: A total of 54/72 (75%) CAPS members practicing in Canada completed the survey. All (100%) agreed they would remove a normal-appearing appendix during laparoscopy for suspected acute appendicitis. The most common reasons were: possibility of microscopic appendicitis (39/54, 72.2%), avoiding future diagnostic confusion (28/54, 51.9%), and patient preference/consent discussion (21/54, 38.9%). Most (53/54, 98.1%) had performed a negative appendectomy and 49/54 (90.7%) agreed there were no sufficient guidelines., Conclusions: The majority of pediatric surgeons agree sufficient guidelines do not exist to support decision making when a normal-appearing appendix is found during laparoscopy for suspected acute appendicitis. This survey shows that removal of the appendix in this case would be supported by the majority of Canadian pediatric surgeons., Type of Study: Survey LEVEL OF EVIDENCE: VII (Expert Opinion)., (Copyright © 2020 Elsevier Inc.

- Abstract
Evidence regarding the prevalence of expiratory flow limitation (EFL) during exercise and the ventilatory response to exercise in children born preterm is limited. This study aimed to determine the prevalence of EFL as well as contributing factors to EFL and the ventilatory response to exercise in preterm children with and without bronchopulmonary dysplasia (BPD). Preterm children (≤32 weeks gestational age) aged 9-12 years with (n=64) and without (n=42) BPD and term controls (n=43), performed an incremental treadmill exercise test with exercise tidal flow-volume loops. More preterm children with BPD (53%) had EFL compared with preterm children without BPD (26%) or term controls (28%) (p<0.05). The presence of EFL was independently associated with decreased forced expiratory volume in 1 s/forced vital capacity z-score and lower gestational age (p<0.05). There was no difference in peak oxygen uptake between preterm children with BPD and term controls (48.0 versus 48.4 mL·kg
-1 ·min-1 ; p=0.063); however, children with BPD had a lower tidal volume at peak exercise (mean difference -27 mL·kg-1 , 95% CI -49- -5; p<0.05). Children born preterm without BPD had ventilatory responses to exercise similar to term controls. Expiratory flow limitation is more prevalent in children born preterm with BPD and is associated with airway obstruction and a lower gestational age., Competing Interests: Conflict of interest: K.

- Abstract
Throughout our day-to-day activities, we are subjected to numerous stimuli that compete for our attention; consequently, we must prioritize stimuli for further processing and influence over behaviour. Previous research has demonstrated that the extent to which task-irrelevant distractors are processed is mediated by the nature of the cognitive task, and the level of processing load. Importantly though, the interaction between cognitive task, processing load, and emotional distractor processing remains unclear. This is a particularly important question given the unique ways that emotion interacts with attention, and the fact that some other forms of processing load have been shown to reduce emotional distractor encoding. In the present study, participants were presented with emotional distractors during a perceptual and working memory task, under varying levels of load. In Experiment 1, we showed that the impact of emotional distractors on behaviour was reduced under conditions of high relative to low perceptual load. However, in sharp contrast, high working memory load was associated with increased emotional distraction. Importantly, these results were replicated in Experiment 2. Overall, the impact of processing load on emotional distraction varies according to the cognitive function being performed. These results raise the intriguing possibility that working memory operations deplete some of the cognitive resources needed to control the impact of emotion on behaviour. The findings, therefore, may have important implications for clinical populations featuring cognitive dysfunction and emotional dysregulation.

- Abstract
Background: Bronchopulmonary dysplasia (BPD) is a common respiratory complication of preterm birth and associated with long-term respiratory sequelae. Chest computed tomography (CT) is a sensitive tool to obtain insight in structural lung abnormalities and may be a predictor for later symptoms., Objectives: To give an overview of chest CT scoring methods that are used to evaluate chest CT scans of BPD patients. To review which structural lung abnormalities are described in children and adults with BPD and whether these are related to clinical outcomes., Methods: An extensive literature search was conducted for relevant studies on chest CT imaging in patients born preterm with BPD., Results: We retrieved 316 original papers of which 16 articles and three abstracts fulfilled our inclusion criteria. Overall, we identified nine different semi-quantitative scoring methods. Chest CT scans revealed structural abnormalities in >85% of BPD patients. These abnormalities are decreased pulmonary attenuation, opacities, bronchial wall thickening, and consolidations. Some have been found to be negatively correlated with lung function and respiratory symptoms., Conclusions: None of the currently described scoring systems are appropriately validated or superior over another. Future studies are needed to generate a validated and universal chest CT quantitative scoring method for patients with BPD.

- Abstract
Background: Pompe disease is a progressive metabolic myopathy. Involvement of respiratory muscles leads to progressive pulmonary dysfunction, particularly in supine position. Diaphragmatic weakness is considered to be the most important component. Standard spirometry is to some extent indicative but provides too little insight into diaphragmatic dynamics. We used lung MRI to study diaphragmatic and chest-wall movements in Pompe disease., Methods: In ten adult Pompe patients and six volunteers, we acquired two static spirometer-controlled MRI scans during maximum inspiration and expiration. Images were manually segmented. After normalization for lung size, changes in lung dimensions between inspiration and expiration were used for analysis; normalization was based on the cranial-caudal length ratio (representing vertical diaphragmatic displacement), and the anterior-posterior and left-right length ratios (representing chest-wall movements due to thoracic muscles)., Results: We observed striking dysfunction of the diaphragm in Pompe patients; in some patients the diaphragm did not show any displacement. Patients had smaller cranial-caudal length ratios than volunteers (p < 0.001), indicating diaphragmatic weakness. This variable strongly correlated with forced vital capacity in supine position (r = 0.88) and postural drop (r = 0.89). While anterior-posterior length ratios also differed between patients and volunteers (p = 0.04), left-right length ratios did not (p = 0.1)., Conclusions: MRI is an innovative tool to visualize diaphragmatic dynamics in Pompe patients and to study chest-walland diaphragmatic movements in more detail. Our data indicate that diaphragmatic displacement may be severely disturbed in patients with Pompe disease.

- Abstract
Purpose: Chemotherapy is often poorly tolerated in elderly patients or patients with poor performance status. This trial was designed to determine whether low-dose weekly docetaxel/estramustine was efficacious with acceptable toxicity., Patients and Methods: Dexamethasone was administered as premedication. Subjects received docetaxel 25 mg/m2 intravenously on days 2, 9, and 16 and estramustine 140 mg orally twice daily on days 1-3, 8-10, and 15-17. Cycles were 28 days. Participants received < or = 6 cycles unless progression or intolerable toxicity occurred., Results: Fifty-eight subjects were enrolled at 31 sites in the US Oncology Network. Median age was 78 years (range, 64-92 years); performance status scores (0, 1, 2, and 3) were 36%, 38%, 24%, and 2%, respectively; 55 subjects received > or = 1 cycle of treatment; and 4 participants were nonevaluable because they completed < 2 cycles. Among the 56 treated subjects, 38 (68%) had a decreased prostate-specific antigen level (> or = 50% compared with baseline level and maintained for 4 weeks). There were 40 subjects with measurable tumor(s). Responses, assessed using Response Evaluation Criteria in Solid Tumors, were 1 complete response (2.5%), 7 partial responses (17.5%), 26 stable diseases (65%), and 6 progressive diseases (15%). At 1 year, 17% of participants were progression free; median progression-free survival was 5.3 months (range, 1-14.5 months); estimated 1-year survival was 65%. There were no grade 4 treatment-related events. Grade 3 treatment-related events included fatigue/asthenia (11%) and arrhythmia, dehydration, cerebral ischemia, thrombocytopenia, and dyspnea (4% each). There was 1 treatment-related death (acute respiratory distress syndrome)., Conclusion: These findings suggest that elderly men with advanced-stage prostate cancer tolerate this regimen, with significant responses and prolonged progression-free survival. These patients should not be excluded from chemotherapeutic interventions based on age alone.

- Abstract
Forty-six previously untreated patients with advanced non-small cell lung cancer (NSCLC) were entered into a Hoosier Oncology Group phase II trial of daily oral etoposide 50 mg/m2/d. The dose limiting toxicity was granulocytopenia. The non-hematologic toxicity was mild, with only 19% of patients developing Grade 3 or 4 leukopenia. Two partial responses of 10 and 16 weeks duration were seen in 43 evaluable patients, for an overall response rate of 4%. We conclude that daily oral etoposide has minimal activity in advanced NSCLC, and does not improve response rates over conventional 1-5 day intravenous etoposide administration.
