    Abstract In this paper we use a contour integral method to derive a bilateral generating function in the form of a double series involving Chebyshev polynomials expressed in terms of the incomplete gamma function. Generating functions for the Chebyshev polynomial are also derived and summarized. Special cases are evaluated in terms of composite forms of both Chebyshev polynomials and the incomplete gamma function.

    Abstract Abstract Issue With the COVID-19 pandemic, the European Union (EU) is faced with an unprecedented crisis with huge effects on every aspect of our society. As European countries start easing lockdowns, discussions on recovery and investment plans pick up the pace, but it will be vital not to repeat mistakes of the past but focus on a healthy, green and just recovery to increase overall health preparedness and resilience in the face of future pandemics. Description of the problem The recovery from the COVID-19 crisis is the litmus test how serious policy-makers are about the EGD, if they take it as the blueprint for rebuilding or continue investing into yesterday's polluting industries and economies. While at EU level there is a strong commitment for the EGD to be the principle in economic recovery, decisions and bailouts at national level do not necessarily follow suit (yet). One of the actions that are needed is defining conditions for all recovery and investment money being spent. Results With EU Commission President's van der Leyen's proposal for a 750 billion EUR recovery fund was presented end of May (1). The European Green Deal (EGD) proposal (2) shows that European Commission has understood the importance of a healthy planet for healthy people. If successfully implemented, this deal has the potential to achieve major health improvements in the near term while reducing the growing health risks from climate change (3,4), air and chemical pollution. Lessons Shifting from a polluting to a green and healthy economy, with the European Green Deal at the core is possible. The EGD already foresees a zero pollution ambition for the EU: preventing all pollution in order to protect health is the much needed goal upon which European and national leaders must base all recovery actions. Key messages A green recovery can give the necessary financial support for upgrading and modernising our cities and sustainable urban planning. Through the imminent recovery decisions, policy-makers need to seize the historic opportunity to reduce the pressure on the planet’s and people’s health.

    Abstract The Wang sum involving the exponential sums of Lerch's Zeta functions is extended to the finite sum of the Huwitz-Lerch Zeta function to derive sums and products involving cosine and tangent trigonometric functions. The general theorem used to derive these sums and products is in the form of the finite sum over positive integers of the Hurwitz-Lerch Zeta function where the associated parameters are general complex numbers. New Hurwitz-Lerch Zeta function recurrence identities with consecutive neighbours are derived. Some finite sum and product formulae examples involving cosine, tangent and the product of cosine and tangent functions are also derived and evaluated.

    Abstract Whether true inter-individual response differences (IIRD) occur as a result of resistance training on body weight and body composition in older adults with overweight and obesity is not known. To address this gap, data from a previous meta-analysis representing 587 men and women (333 resistance training, 254 control) ≥ 60 years of age nested in 15 randomized controlled trials of resistance training ≥ 8 weeks were included.

    Abstract Background: Point-of-care testing in the emergency department decreases wait times and supports evidence-based patient care. However, hurdles to successful implementation include management of interdisciplinary work flows and establishment of an effective quality control program. As COVID-19 testing is now integrated into screening protocols in emergency and urgent care settings, hospital systems must maintain flexible and adaptable respiratory virus testing to adapt to regional trends in transmission. In response to this challenge, our hospital system established a point-of-care respiratory virus laboratory within the emergency department to test for COVID, influenza A/B, and respiratory syncytial virus (RSV). However, maintaining regulatory compliance and standardized protocols within such a dynamic environment became challenging.
    Methods: We launched a quality improvement initiative to support improved performance and efficiency in the point-of-care laboratory with a focus on regulatory benchmarks. Following a period of observation and discussion with key stakeholders in the emergency department and pathology, an audit tool was developed and to be deployed in collaboration with ED nursing. Utilizing the new tool, ED nursing would perform audits in parallel to audits performed by point-of-care staff.
    Results: Prior to the intervention, the average audit score was approximately 55%; 6 months following the intervention, audit scores have remained stable at approximately 80%, representing a significant improvement in regulatory compliance.
    Conclusions: Creation of a regulatory tool enabled real-time cross-departmental monitoring of regulatory compliance. These findings underscore the importance of developing transparent interdisciplinary work flows and effective communication to improve patient care.

  10. Article ; Online: A propensity score-matched analysis of laparoscopic versus open pancreaticoduodenectomy: Is there value to a laparoscopic approach?

    Abstract Background: Laparoscopic pancreaticoduodenectomy has been found safe and associated with advantages over open pancreaticoduodenectomy in prior studies. We compared outcomes of laparoscopic pancreaticoduodenectomy versus open pancreaticoduodenectomy at a single institution after applying technical aspects and perioperative care learned from laparoscopic pancreaticoduodenectomy to the open pancreaticoduodenectomy practice.
    Methods: From January 2010 to December 2020, all patients undergoing pancreaticoduodenectomy were identified, and information was collected in a prospective fashion. Open pancreaticoduodenectomy (n = 347) and laparoscopic pancreaticoduodenectomy (n = 242) were performed using the same selection criteria, operative technique, and recovery protocols at a single institution. Propensity score matching was performed, and then perioperative data and 90-day outcomes were compared, and statistical analysis was performed.
    Results: A total of 589 patients underwent pancreaticoduodenectomy, including open pancreaticoduodenectomy (n = 347) and laparoscopic pancreaticoduodenectomy (n = 242). After excluding those undergoing total pancreatectomy or major vascular or concomitant organ resection, there were 497 patients (open pancreaticoduodenectomy = 301 and laparoscopic pancreaticoduodenectomy = 196). Propensity score matching was performed, and 187 open pancreaticoduodenectomy patients were matched to 187 laparoscopic pancreaticoduodenectomy patients. Operative time (475 vs 280 minutes) was longer, and estimated blood loss (150 vs 212 mL) was less for laparoscopic pancreaticoduodenectomy than open pancreaticoduodenectomy, respectively. Pancreatic fistula (18.8% vs 5.4%) and delayed gastric emptying (18.8% vs 9.7%) were higher for laparoscopic pancreaticoduodenectomy than open pancreaticoduodenectomy, respectively. Postpancreatectomy hemorrhage, major morbidity, mortality, hospital stay, and readmissions were nonsignificantly higher for laparoscopic pancreaticoduodenectomy than open pancreaticoduodenectomy. Intensive care use and overall costs were significantly higher for laparoscopic pancreaticoduodenectomy than open pancreaticoduodenectomy.
    Conclusion: In our experience, open pancreaticoduodenectomy offers similar to improved outcomes over laparoscopic pancreaticoduodenectomy, with less use of perioperative resources, thereby offering better value to patients requiring pancreaticoduodenectomy.
