Background: Use of tobacco poses significant health risks, particularly in surgical patients, where smoking is a well-established risk factor for postoperative complications. Patients are often seen in the pre-assessment clinic 2-4 weeks prior to surgery, presenting a window of opportunity to intervene. The objective of our systematic review and meta-analysis is to explore the impact of short-term smoking cessation on postoperative outcomes, focusing on the critical 2-4-week period preceding surgery.

During lucid dreaming (LD), dreamers are aware that they are dreaming and may be able to influence the oneiric content. There has been recent debate about the relative importance of the ability to influence the dream and having agency over the pure awareness of dreaming. To underline this, we examined the associations of lucid dreams without agency (LD-Ag) and lucid dreams with agency (LD + Ag) to sleep and mental health problems and long COVID during the pandemic.

This study aimed to (1) examine the diagnostic performance of two ultra-rapid cognitive screening tools, the Ascertain Dementia Eight-item Questionnaire (AD8) and Mini-Cog, against a tool validated in surgical populations, the Montreal Cognitive Assessment (MoCA); and (2) compare preoperative patient-centered assessments and postoperative outcomes between those with and without cognitive impairment (CI).
Methods: CI was classified by scoring ≥2 on the AD8, ≤2 on the Mini-Cog, and/or ≤25 on the MoCA in non-cardiac patients ≥65 years old.

Background: Frailty is a state of increased vulnerability and decreased physiological reserve, which can reduce one's capacity to cope with external stressors such as a major surgery. We aimed to (1) investigate the preoperative and postoperative prevalence of frailty in older surgical patients; and (2) evaluate preoperative risk factors associated with postoperative frailty.
Methods: This multicentre prospective study included 307 non-cardiac surgical patients aged ≥65 years.
Study Objectives: To identify common preoperative concerns in older surgical populations and explore their attitudes towards prehabilitation, functional, and cognitive assessments.
Design: Multicenter cross-sectional study.
Setting: Preoperative questionnaire examining preoperative concerns and attitudes towards prehabilitation, functional, and cognitive assessments.
Background: Further characterization is needed to capture the trajectory of health-related quality of life in older surgical populations with cognitive impairment. This study aimed to (1) compare the perioperative trajectory of health-related quality of life between older noncardiac surgical patients with and without cognitive impairment; (2) assess preoperative health-related quality of life values associated with adverse clinical outcomes; and (3) explore preoperative factors associated with poorer health-related quality of life over time.
Methods: Health-related quality of life was assessed online using the EuroQol 5-Dimension 5-Level questionnaire preoperatively and postoperatively at 30, 90, and 180 days.
Background: A longitudinal examination of postoperative depression is important for risk assessment. We aimed to explore the prevalence and trajectory of depression in older surgical patients, before surgery, and at 30, 90, and 180 days after surgery, associated risk factors, and clinical outcomes.
Methods: This prospective cohort study assessed 307 male and female surgical patients aged ≥65 yr in two preoperative clinics in Canada.
Introduction: The prevalence of dementia is rising due to an aging population. Given the known risks of obstructive sleep apnea (OSA) on cerebrovascular health, we hypothesized that markers of OSA would correlate with reduced hippocampal volumes in individuals with cognitive impairment due to neurodegenerative, vascular, or mixed (NVM) etiologies.
Methods: Data from 166 patients were retrospectively analyzed.
The present study aimed to describe the prevalence rates of frequent (i.e., at least weekly) dream recall and nightmares with consideration for differences in age, gender and sleep duration in 16 countries using equivalent assessment methods.

The present overview comprehensively discusses the findings from this collaboration. Involving sleep researchers across the globe, ICOSS used a harmonised questionnaire to cover changes in sleep and sleep disorders, as well as physical and mental health.

Previous reviews estimated postoperative neurocognitive disorder or cognitive dysfunction (POCD) prevalence without accounting for the sample size or study quality. The prevalence of POCD in this population requires further investigation.

With the inclusion of patient and public involvement, we undertook a Delphi consensus process to update previously recommended endpoints to be used in clinical trials evaluating treatments aiming to improve patient comfort after surgery.
Methods: We undertook a systematic review to identify domains and outcome measures of patient comfort used in perioperative studies.

Background And Aims: Postoperative sleep disturbances are associated with delayed recovery and increased incidences of complications. This systematic review aims to determine the impact of perioperative pharmacological therapies on postoperative sleep quality in the hospital.
Material And Methods: We searched MEDLINE, MEDLINE ePubs and In-Process Citations (Daily), Embase Classic + Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and PubMed for randomized controlled trials (RCTs) from inception to May 2022, with continued literature surveillance until August 2023.
Background And Aims: Delayed neurocognitive recovery (DNR) and postoperative neurocognitive disorder (P-NCD) are common postoperative complications affecting older patients. This review evaluates perioperative approaches for preventing DNR and P-NCD in older noncardiac surgical patients.
Material And Methods: We searched databases for relevant articles from inception through June 2022 and updated in May 2023 (PROSPERO ID CRD42022359289).

Respiratory depression during sleep is a major health challenge after surgery. The main cause is reduction in breathing due to opioids, which are commonly used for management of postoperative pain. The consequences are hypoxemia and hypercapnia, which may increase the risk of cardiovascular complications, mortality, and healthcare utilization.
View Article and Find Full Text PDFAims: Early detection and management of sleep disturbances can improve postoperative outcomes given the high prevalence of sleep disturbances and unrecognized cognitive impairment in older surgical patients. There is an association between sleep disturbances and cognitive impairment in the general population. However, the relationship in older surgical patients has not been systematically investigated.

This systematic review and meta-analysis aimed to evaluate the risk of peri-procedural adverse events in OSA patients undergoing procedural sedation in ambulatory settings, compared to those without OSA.
Methods: Four databases were systematically searched for studies published from January 1, 2011 to January 4, 2024.
Background: There is a significant gap in research exploring changes in postoperative health-related quality of life (HRQoL) among patients aged 65 years and older undergoing hip or knee arthroplasty.
Objectives: To investigate the variations in HRQoL improvement, as evaluated by patient-reported outcome measures following total hip arthroplasty, total knee arthroplasty, and partial knee arthroplasty between the young-old and old-old adults.
Methods/design: We searched six online databases (including MEDLINE, Embase) from their inception dates to May 15, 2023.

Study Rationale: Although the STOP-Bang questionnaire has been validated for its efficacy and diagnostic performance in various settings, there is no review that summarizes the pertinent evidence of the STOP-Bang questionnaire in the different populations. We aimed to review the evidence of the diagnostic performance of the STOP-Bang questionnaire, correlation between STOP-Bang scores and the probability of obstructive sleep apnea (OSA), and its clinical application in various populations.
Study Impact: This review guides healthcare providers in the sleep medicine and perioperative medicine disciplines to be better informed when using the STOP-Bang questionnaire in the different populations.
