The effect of the type of anaesthesia on long-term outcomes after cancer resection surgery: a narrative review.

Background: The peri-operative period may create a biological environment conducive to cancer cell survival and dissemination. Microscopic residual tumours (micrometastases) can be dislodged even with excellent surgical technique. At the same time, the stress response from surgery can temporarily impair immune function and activate inflammatory processes, increasing the risk of tumour proliferation.

SSO optimized FOFPID regulator design for performance enhancement of doubly fed induction generator based wind turbine system.

A wind turbine system (WTS) is a highly coupled and nonlinear system where the output power depends upon highly uncertain wind speed. Therefore, the quality of produced power becomes a challenging problem for researchers. Direct Vector Control (DVC) is a powerful and widely utilized power control strategy to deal with winds that vary rapidly and randomly.

New avenue of diagnostic stewardship: procedural stewardship for recurrent urinary tract infections in female patients.

Introduction: Societal guidelines offer a weak recommendation to perform cystoscopy for female patients with recurrent urinary tract infections (rUTI) of advanced age and/or with high-risk features. These guidelines lack the support of robust data and are instead based on expert opinion. In this retrospective cohort study, we aim to determine the utility of cystoscopy in patients with and without high-risk features for rUTI.

Anaesthesia and cancer recurrence: the influence of perioperative anaesthetic technique on cancer recurrence after surgery.

Purpose Of Review: Cancer is a leading cause of death worldwide, and incidence is increasing. Excisional surgery is essential in approximately 70% of solid organ tumours. Emerging research in onco-anaesthesiology suggests that perioperative anaesthetic and analgesic techniques might influence long-term oncologic outcomes.

How Often Do You Think About Your Relationship With Nature? The Measurement of Environmental Identity Salience and Its Relationship With Proenvironmental Behaviors.

Extant research finds that environmental identity is an important motivational factor for proenvironmental behavior. However, studies typically focus on investigating the effects of the strength of this identity. Based on insights from identity research, we theorize that the influence of individuals' environmental identity on their proenvironmental behavior may depend on other identity dimensions as well.

Effects of curcumin supplementation on vitamin D levels in women with premenstrual syndrome and dysmenorrhea: a randomized controlled study.

Background: Vitamin D has an established role in female reproduction. There is also evidence for an association between vitamin D levels and menstrual problems such as premenstrual syndrome (PMS) and dysmenorrhea. Curcumin, is a bioactive polyphenol constituent of turmeric, that can potentially interact with vitamin D receptors and its molecular targets.

Tracheal intubation in the critically ill patient.

Tracheal intubation is among the most commonly performed and high-risk procedures in critical care. Indeed, 45% of patients undergoing intubation experience at least one major peri-intubation adverse event, with cardiovascular instability being the most common event reported in 43%, followed by severe hypoxemia in 9% and cardiac arrest in 3% of cases. These peri-intubation adverse events may expose patients to a higher risk of 28-day mortality, and they are more frequently observed with an increasing number of attempts to secure the airway.

Effects of Soy Isoflavones on Glycemic Parameters and Blood Pressure in Peritoneal Dialysis Patients: A Randomized, Double Blind, Placebo-Controlled Trial.

Introduction: High serum concentrations of glucose, advanced glycation end products (AGEs), and hypertension are some of the major risk factors for cardiovascular disease and peritoneal membrane fibrosis in peritoneal dialysis (PD) patients. Some investigations in nonuremic individuals have indicated that isoflavones can reduce serum glucose, blood pressure, and increase insulin sensitivity. However, such study in this field in PD patients is still lacking.

Tomato powder is more effective than lycopene to alleviate exercise-induced lipid peroxidation in well-trained male athletes: randomized, double-blinded cross-over study.

Background: Consumption of nutritional supplements to optimize recovery is gaining popularity among athletes. Tomatoes contain micronutrients and various bioactive components with antioxidant properties. Many of the health benefits of tomatoes have been attributed to lycopene encouraging athletes to consume pure lycopene supplements.

Connectedness With Nature and Individual Responses to a Pandemic: An Exploratory Study.

Most recent epidemics have originated in complex human-nature interactions and yet, our knowledge is very limited regarding the psychological aspects of human-nature relationships that underlie individual human responses in times of pandemic crises. We propose that the concept of connectedness with nature and associated individual difference measures offer a relevant and useful lens to inform us about how humans think, feel and behave in such critical times. Our two-wave study, conducted with 486 United States residents at the end of March 2020 (wave 1) and 533 United States residents at the beginning of May 2020 (wave 2), focuses on the 2020 coronavirus situation.

High doses of sodium nitrate prior to exhaustive exercise increases plasma peroxynitrite levels in well-trained subjects: randomized, double-blinded, crossover study.

Ten well-trained male subjects participated in a randomized, double-blinded, crossover study. They ingested 8, 16, and 24 mmol sodium nitrate or placebo (NaCl) dissolved in water at 2.

Carbon nanotube as a carrier in drug delivery system for carnosine dipeptide: A computer simulation study.

Biological application of carbon nanotube in drug delivery is our main concern in this investigation.

Design and real time implementation of single phase boost power factor correction converter.

This paper presents a real time implementation of the single-phase power factor correction (PFC) AC-DC boost converter. A combination of higher order sliding mode controller based on super twisting algorithm and predictive control techniques are implemented to improve the performance of the boost converter. Due to the chattering effects, the higher order sliding mode control (HOSMC) is designed.

This paper proposes analysis and control of a single-phase power factor corrector (PFC). The proposed control is capable of achieving a unity power factor for each DC link voltage or load fluctuation. The method under study is composed of two intelligent approaches, a fuzzy logic controller to ensure an output voltage at a suitable value and predictive current control.

Effects of oral enalapril and verapamil on dialysis adequacy and solute clearance in chronic ambulatory peritoneal dialysis.

Peritoneal dialysis offers several advantages such as better clearance of intermediate/large molecules and better preservation of renal residual function when compared with hemodialysis. However, dialysis adequacy is one of the subjects of concern of this modality. There are some drugs that are capable of influencing solute transport in the peritoneum, such as acetyle co-enzyme inhibitors (ACE-I) medications and calcium channel blockers.

Analysis and design of sliding mode controller gains for boost power factor corrector.

This paper presents a systematic procedure to compute the gains of sliding mode controller based on an optimization scheme. This controller is oriented to drive an AC-DC converter operating in continuous mode with power factor near unity, and in order to improve static and dynamic performances with large variations of reference voltage and load. This study shows the great influence of the controller gains on the global performances of the system.
