Lipid metabolic reprogramming mediated by circulating Nrg4 alleviates metabolic dysfunction-associated steatotic liver disease during the early recovery phase after sleeve gastrectomy.

BACKGROUND: The metabolic benefits of bariatric surgery that contribute to the alleviation of metabolic dysfunction-associated steatotic liver disease (MASLD) have been reported. However, the processes and mechanisms underlying the contribution of lipid metabolic reprogramming after bariatric surgery to attenuating MASLD remain elusive. METHODS: A case-control study was designed to evaluate the impact of three of the most common adipokines (Nrg4, leptin, and adiponectin) on hepatic steatosis in the early recovery phase following sleeve gastrectomy (SG). A series of rodent and cell line experiments were subsequently used to determine the role and mechanism of secreted adipokines following SG in the alleviation of MASLD. RESULTS: In morbidly obese patients, an increase in circulating Nrg4 levels is associated with the alleviation of hepatic steatosis in the early recovery phase following SG before remarkable weight loss. The temporal parameters of the mice confirmed that an increase in circulating Nrg4 levels was initially stimulated by SG and contributed to the beneficial effect of SG on hepatic lipid deposition. Moreover, this occurred early following bariatric surgery. Mechanistically, gain- and loss-of-function studies in mice or cell lines revealed that circulating Nrg4 activates ErbB4, which could positively regulate fatty acid oxidation in hepatocytes to reduce intracellular lipid deposition. CONCLUSIONS: This study demonstrated that the rapid effect of SG on hepatic lipid metabolic reprogramming mediated by circulating Nrg4 alleviates MASLD.

Influence of Postoperative Insulin Resistance on Short-Term Outcomes of Radical Gastrectomy for Gastric Cancer: A Microbiome and Metabolome-Based Prospective Cohort Study.

BACKGROUND: Gastrectomy is one of the main treatment modalities for gastric cancer (GC) and induces pathophysiological changes that significantly affect patients' postoperative recovery. In this study, we investigated the relationships between altered insulin resistance (IR), inflammation, and gut microbiota associated with gastrectomy. PATIENTS AND METHODS: This study was a single-center prospective cohort investigation involving 60 patients with GC who underwent gastrectomy between May 2023 and April 2024. Monitoring encompassed IR, inflammation, and nutrition-related markers via blood assays, while gut microbiota analysis employed high-throughput sequencing, and short-chain fatty acids (SCFAs) were examined through targeted metabolomics. The study is registered under the number ChiCTR2300075653. RESULTS: The patients exhibited a significant increase in post-gastrectomy IR markers (P < 0.001), accompanied by elevated inflammation markers (P < 0.001), and also showed decreased nutrition-related indicators (P < 0.001). Notable alterations were observed in the gut microbiota, including reductions in Bifidobacterium and Faecalibacterium, an increase in Streptococcus, and a noteworthy decrease in fecal butyrate. Patients with postoperative IR exhibited poorer inflammation markers (P < 0.05), nutritional indicators (P < 0.05), and postoperative recovery parameters (P < 0.05). Furthermore, significant negative correlations were observed between IR and Bifidobacterium, Faecalibacterium, as well as butyrate. CONCLUSIONS: Patients with GC post-gastrectomy displayed heightened IR, exacerbated inflammation, and compromised nutritional status. Disturbed gut microbiota and reduced fecal butyrate were observed. Gut microbiota and metabolite butyrate production may be predictors of postoperative IR and short-term outcomes in patients with GC.

Feasibility and Accuracy of Wrist-Worn Sensors for Perioperative Monitoring During and After Major Abdominal Surgery: An Observational Study.

INTRODUCTION: Continuous, ambulatory perioperative monitoring using wearable devices has shown promise for earlier detection of physiological deterioration and postoperative complications, preventing 'failure-to-rescue'. This study aimed to compare the accuracy of vital signs measured by wrist-based wearables with gold standard measurements from vital signs monitors or nurse assessments in major abdominal surgery. METHODS: Adult patients were eligible for inclusion in this prospective observational study validating the Empatica E4 wrist sensor intraoperatively and postoperatively. The primary outcomes were the 95% limits of agreement (LoA) between manual and device recordings of heart rate (HR) and temperature evaluated via Bland-Altman analysis. Secondary analysis was conducted using Clarke-Error grid analysis. RESULTS: Overall, 31 patients were recruited, and 27 patients completed the study. The median duration of recording per patient was 70.3 h, and a total of 2112 h of data recording were completed. Wrist-based HR measurement was accurate and moderately precise (bias: 0.3 bpm; 95% LoA -15.5 to 17.1), but temperature measurement was neither accurate nor precise (bias -2.2°C; 95% LoA -6.0 to 1.6). On Clarke-Error grid analysis, 74.5% and 29.6% of HR and temperature measurements, respectively, fell within the acceptable range of reference standards. CONCLUSIONS: Continuous perioperative monitoring of HR and temperature after major abdominal surgery using wrist-based sensors is feasible but was limited in this study by low precision. While wrist-based devices offer promise for the continuous monitoring of high-risk surgical patients, current technology is inadequate. Ongoing device hardware and software innovation with robust validation is required before such technologies can be routinely adopted in clinical practice.

Perioperative Gastrointestinal Myoelectric Activity Measurement Using Wireless External Patches.

BACKGROUND: Stomach, small intestine, and colon have distinct patterns of contraction related to their function to mix and propel enteric contents. In this study, we aim to measure gut myoelectric activity in the perioperative course using external patches in an animal model. METHODS: Four external patches were placed on the abdominal skin of female Yucatan pigs to record gastrointestinal myoelectric signals for 3 to 5 d. Pigs subsequently underwent anesthesia and placement of internal electrodes on stomach, small intestine, and colon. Signals were collected by a wireless transmitter. Frequencies associated with peristalsis were analyzed for both systems for 6 d postoperatively. RESULTS: In awake pigs, we found frequency peaks in several ranges, from 4 to 6.5 cycles per minute (CPM), 8 to 11 CPM, and 14 to 18 CPM, which were comparable between subjects and concordant between internal and external recordings. The possible effect of anesthesia during the 1 or 2 h before surgical manipulation was observed as a 59% (±36%) decrease in overall myoelectric activity compared to the immediate time before anesthesia. The myoelectrical activity recovered quickly postoperatively. Comparing the absolute postsurgery activity levels to the baseline for each pig revealed higher overall activity after surgery by a factor of 1.69 ± 0.3. CONCLUSIONS: External patch measurements correlated with internal electrode recordings. Anesthesia and surgery impacted gastrointestinal myoelectric activity. Recordings demonstrated a rebound phenomenon in myoelectric activity in the postoperative period. The ability to monitor gastrointestinal tract myoelectric activity noninvasively over multiple days could be a useful tool in diagnosing gastrointestinal motility disorders.

Effect and mechanism of needleless transcutaneous neuromodulation on gastrointestinal function after pancreaticoduodenectomy.

BACKGROUND: Gastrointestinal motility disorders tend to develop after pancreaticoduodenectomy (PD). The objectives of this study were: (1) to investigate the impact of needleless transcutaneous neuromodulation (TN) on the postoperative recuperation following pancreaticoduodenectomy (PD), and (2) to explore the underlying mechanisms by which TN facilitates the recovery of gastrointestinal function after PD. METHODS: A total of 41 patients scheduled for PD were randomized into two groups: the TN group (n = 21) and the Sham-TN group (n = 20). TN was performed at acupoints ST-36 and PC-6 twice daily for 1 h from the postoperative day 1 (POD1) to day 7. Sham-TN was performed at non-acupoints. Subsequent assessments incorporated both heart rate variation and dynamic electrogastrography to quantify alterations in vagal activity (HF) and gastric pacing activity. RESULTS: 1)TN significantly decreased the duration of the first passage of flatus (p < 0.001) and defecation (p < 0.01) as well as the time required to resume diet (p < 0.001) when compared to sham-TN;2)Compared with sham-TN, TN increased the proportion of regular gastric pacing activity (p < 0.01);3) From POD1 to POD7, there was a discernible augmentation in HF induced by TN stimulation(p < 0.01);4) TN significantly decreased serum IL-6 levels from POD1 to POD7 (p < 0.001);5) TN was an independent predictor of shortened hospital stay(ß = - 0.349, p = 0.035). CONCLUSION: Needleless TN accelerates the recovery of gastrointestinal function and reduces the risk of delayed gastric emptying in patients after PD by enhancing vagal activity and controlling the inflammatory response.

Adverse outcomes after surgery after a cerebrovascular accident or acute coronary syndrome: a retrospective observational cohort study.

BACKGROUND: Delaying surgery after a major cardiovascular event might reduce adverse postoperative outcomes. The time interval represents a potentially modifiable risk factor but is not well studied. METHODS: This was a longitudinal retrospective population-based cohort study, linking data from Hospital Episode Statistics for NHS England and the Myocardial Ischaemia National Audit Project. Adults undergoing noncardiac, non-neurologic surgery in 2007-2018 were included. The time interval between a preoperative cardiovascular event and surgery was the main exposure. The outcomes of interest were acute coronary syndrome (ACS), acute myocardial infarction (AMI), cerebrovascular accident (CVA) within 1 year of surgery, unplanned readmission (at 30 days and 1 year), and prolonged length of stay. Multivariable logistic regression models with restricted cubic splines were used to estimate adjusted odds ratios (aORs; age, sex, socioeconomic deprivation, and comorbidities). RESULTS: In total, 877 430 people had a previous cardiovascular event and 20 582 717 were without an event. CVA, ACS, and AMI in the year after elective surgery were more frequent after prior cardiovascular events (adjusted hazard ratio 2.12, 95% confidence interval [CI] 2.08-2.16). Prolonged hospital stay (aOR 1.36, 95% CI 1.35-1.38) and 30-day (aOR 1.28, 95% CI 1.25-1.30) and 1-yr (aOR 1.60, 95% CI 1.58-1.62) unplanned readmission were more common after major operations in those with a prior cardiovascular event. After adjusting for the time interval between preoperative events until surgery, elective operations within 37 months were associated with an increased risk of postoperative ACS or AMI. The risk of postoperative stroke plateaued after a 20-month interval until surgery, irrespective of surgical urgency. CONCLUSIONS: These observational data suggest increased adverse outcomes after a recent cardiovascular event can occur for up to 37 months after a major cardiovascular event.

Digital health interventions for postoperative recovery in children: a systematic review.

BACKGROUND: Digital health interventions offer a promising approach for monitoring during postoperative recovery. However, the effectiveness of these interventions remains poorly understood, particularly in children. The objective of this study was to assess the efficacy of digital health interventions for postoperative recovery in children. METHODS: A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, with the use of automation tools for searching and screening. We searched five electronic databases for randomised controlled trials or non-randomised studies of interventions that utilised digital health interventions to monitor postoperative recovery in children. The study quality was assessed using Cochrane Collaboration's Risk of Bias tools. The systematic review protocol was prospectively registered with PROSPERO (CRD42022351492). RESULTS: The review included 16 studies involving 2728 participants from six countries. Tonsillectomy was the most common surgery and smartphone apps (WeChat) were the most commonly used digital health interventions. Digital health interventions resulted in significant improvements in parental knowledge about the child's condition and satisfaction regarding perioperative instructions (standard mean difference=2.16, 95% confidence interval 1.45-2.87; z=5.98, P<0.001; I2=88%). However, there was no significant effect on children's pain intensity (standard mean difference=0.09, 95% confidence interval -0.95 to 1.12; z=0.16, P=0.87; I2=98%). CONCLUSIONS: Digital health interventions hold promise for improving parental postoperative knowledge and satisfaction. However, more research is needed for child-centric interventions with validated outcome measures. Future work should focus development and testing of user-friendly digital apps and wearables to ease the healthcare burden and improve outcomes for children. SYSTEMATIC REVIEW PROTOCOL: PROSPERO (CRD42022351492).

Programmed intermittent bolus versus continuous infusion for catheter-based erector spinae plane block on quality of recovery in thoracoscopic surgery: a single-centre randomised controlled trial.

BACKGROUND: Regional anaesthesia techniques, including the erector spinae fascial plane (ESP) block, reduce postoperative pain after video-assisted thoracoscopic surgery (VATS). Fascial plane blocks rely on spread of local anaesthetic between muscle layers, and thus, intermittent boluses might increase their clinical effectiveness. We tested the hypothesis that postoperative ESP analgesia with a programmed intermittent bolus (PIB) regimen is better than a continuous infusion (CI) regimen in terms of quality of recovery after VATS. METHODS: We undertook a prospective, double-blinded, randomised, controlled trial involving 60 patients undergoing VATS. All participants received ESP block catheters and were randomly assigned to CI or PIB of local anaesthetic regimen for postoperative analgesia. The primary outcome was Quality of Recovery-15 (QoR-15) score 24 h after surgery. Secondary outcomes included postoperative respiratory function, opioid consumption, verbal rating pain score, time to first mobilisation, nausea, vomiting, and length of hospital stay. RESULTS: Overall QoR-15 scores at 24 h after VATS were similar (PIB 115.5 [interquartile range 107-125] vs CI 110 [93-128]; Δ<6, P=0.29). The only quality of recovery descriptor showing a significant difference was nausea and vomiting, which was favourable in the PIB group (10 [10-10] vs 10 [7-10]; P=0.03). Requirement for rescue antiemetics up to 24 h after surgery was lower in the PIB group (4 [14%] vs 11 [41%]; P=0.04). There were no differences in other secondary outcomes between groups. CONCLUSIONS: Delivering ESP block analgesia after VATS via a PIB regimen resulted in similar QoR-15 at 24 h compared with a CI regimen.

Outcomes reported in elective colorectal cancer surgery research for older patients: A scoping review.

AIM: Colorectal cancer rates are increasing in older populations, who often have comorbidities and face higher surgical risks and mortality rates. Therefore, surgical outcomes, such as 5-year mortality rates, may not be appropriate, necessitating a focus on postoperative quality of life. However, determining optimal postoperative outcome measures for older colorectal cancer patients poses a challenge. This scoping review aimed to explore currently available data describing postoperative outcomes used to assess older patients undergoing elective colorectal cancer surgery. METHOD: We conducted a comprehensive literature search of major electronic databases from inception to March 2023. Studies exploring frail or older individuals with colorectal cancer undergoing elective surgical procedures, and which reported postoperative outcomes, were included. Outcomes were categorized as surgery-specific versus person-centred and summarized using narrative synthesis. The type and rate of surgery-specific outcomes were tabulated. RESULTS: Of 1366 identified citations, 16 studies focused on person-centred outcomes and 66 reported exclusively on surgery-specific outcomes. Nine 'person-centred outcome' studies reported discharge destination, primarily home discharge. Postoperative delirium ranged from 8.2% to 18.1% in six studies. Four studies explored geriatric syndromes, three analysed activities of daily living, and three studies reported significant quality of life improvement. The 66 'surgery-specific outcome' studies assessed mortality (N = 61); length of stay (N = 40); postoperative complications (N = 47); readmission (N = 18); reoperation (N = 16); and survival (N = 42). CONCLUSION: Person-centred outcomes are underreported, but crucial for guiding patient management. Older patients require adequate information about their postoperative recovery period to enhance wellbeing. Future research must address this gap to improve care for older people undergoing elective colorectal cancer surgery.

Retrospective analysis of preoperative application of triple-modal pre-rehabilitation on postoperative recovery of colorectal cancer patients.

PURPOSE: To retrospectively analyze the difference between triple-modal pre-rehabilitation and common treatment in patients with colorectal cancer (CRC). METHODS: A total of 145 patients with CRC diagnosed by pathology and admitted to our hospital for surgery between June 2020 and June 2022 were included in the study. All patients were divided into two groups: the triple-modal pre-rehabilitation group (pre-rehabilitation group) and the common treatment group. The triple-modal pre-rehabilitation strategy included exercise (3-5 times per week, with each session lasting more than 50 min), nutritional support, and psychological support. The study was designed to assess the potential of the pre-rehabilitation intervention to accelerate postoperative recovery by assessing the 6-min walk test, nutritional indicators, and HADS score before and after surgery. RESULTS: The pre-rehabilitation intervention did not reduce the duration of initial postoperative recovery or the incidence of postoperative complications, but it did increase the patients' exercise capacity (as determined by the 6-min walk test), with the pre-rehabilitation group performing significantly better than the common group (433.0 (105.0) vs. 389.0 (103.5), P < 0.001). The study also found that triple-modal pre-rehabilitation was beneficial for the early recovery of nutritional status in surgical patients and improved anxiety and depression in patients after surgery, especially in those who had not received neoadjuvant therapy. CONCLUSION: The triple-modal pre-rehabilitation strategy is of significant importance for reducing stress and improving the functional reserve of patients with colorectal cancer (CRC) during the perioperative period. The results of our study provide further support for the integration of the triple-modal pre-rehabilitation strategy into the treatment and care of CRC patients.

Outpatient surgery postoperative ambulation and emergency department utilization.

BACKGROUND: The ability to ambulate is an important indicator for wellness and quality of life. A major health event, such as a surgery, can derail this ability, and return to preoperative walking ability is a marker for recovery. Self-reported walking measurements by patients are subject to bias, thus wearable technology such as activity monitors have risen in popularity. We evaluated postoperative ambulation using an accelerometer in outpatient general surgery procedures with the hypothesis that those patients with less postoperative ambulation were at risk for adverse outcomes. METHODS: A retrospective review of patients undergoing outpatient abdominal surgeries from November 2016 to July 2019 at a Veteran Affairs Medical Center. Patients wore an accelerometer preoperatively and postoperatively to measure their ambulation (steps/day). Outcome measures were 30-day readmissions and Emergency Department (ED) utilization. Postoperative ambulation was defined as daily percentages of their preoperative baseline. Patients without preoperative baseline data, > 3 missing days or any missing days prior to reaching baseline were excluded. RESULTS: One-hundred-six patients underwent outpatient abdominal surgery. Twenty-two patients were excluded. Patients stratified into adult (18-64 years, 44 patients, 52%) and geriatric (≥ 65 years, 40 patients, 48%) cohorts. Geriatric patients were less likely to meet their preoperative baseline by postoperative day 7, 35% vs 61%, p = 0.016. Adult patients who failed to meet their preoperative baseline in first postoperative week had higher ED utilization; 4 (24%) vs 1 (4%), p = 0.04. Geriatric patients who failed to meet their baseline trended toward increased ED utilization; 5 (19%) vs. 1 (7%), p = 0.31. CONCLUSION: Patients aged < 65 who fail to return to their preoperative daily step count within one week of outpatient abdominal surgery are 6× more likely to be seen in the ED. Postoperative ambulation may be able to predict ED utilization and recovery after outpatient surgery.

Early oral feeding within two hours for parturients compared with delayed oral feeding after cesarean section: a systematic review and meta-analysis.

BACKGROUND: It is recommended that postpartum women undergo early oral feeding (EOF) after cesarean section (CS). However, the optimal early time for oral feeding after CS is unclear. We performed a meta-analysis to assess whether EOF within two hours is superior to delayed oral feeding (DOF) after CS. METHODS: The PubMed, Embase, Cochrane Library, and Google Scholar databases were searched from inception to February 2024 for randomized controlled trials comparing EOF versus DOF after CS. Primary outcomes included the time to normal bowel function. The secondary outcomes included postoperative complications, the time to ambulation after surgery, the time to removal of the catheter, the time to start of a regular diet, the length of hospital stay and patient satisfaction. RESULTS: Data from 8 studies involving a total of 2572 women were obtained. EOF within two hours was significantly associated with shorter durations of return bowel movement (WMD, - 2.41, 95% CI, - 3.80-- 1.02; p < 0.001; I2 = 96%), passage flatus after surgery (WMD, - 3.55, 95% CI, - 6.36-- 0.75; p = 0.01; I2 = 98%), ambulation after surgery (WMD, - 0.96, 95% CI, - 1.80-- 0.13; p = 0.02; I2 = 53%), removal of catheters (WMD, - 15.18, 95% CI, - 25.61-- 4.74; p = 0.004; I2 = 100%) and starting a regular diet (WMD, - 7.03, 95% CI, - 13.13-- 0.92; p = 0.02; I2 = 99%) compared with DOF. EOF was not related to increased vomiting (RR, 1.08; 95% CI, 0.74-1.57; p = 0.69; I2 = 0%), nausea (RR, 1.21; 95% CI, 0.83-1.77; p = 0.33; I2 = 37%), abdominal distension (RR, 0.76; 95% CI, 0.31-1.89; p = 0.55; I2 = 54%) or ileus (RR, 0.91; 95% CI, 0.40-2.06; p = 0.81; I2 = 12%). CONCLUSIONS: This meta-analysis provides evidence that EOF within two hours after CS has comparable safety with DOF, and can accelerate the recovery time for normal bowel function.

Comparison of the Outcomes of Enhanced Recovery After Surgery and Traditional Recovery Pathway in Robotic Hysterectomy for Benign Indications: A Randomized Controlled Trial.

STUDY OBJECTIVE: The present study aimed to evaluate the impact of the implementation of the enhanced recovery after surgery (ERAS) program in patients undergoing robotic hysterectomy for benign indications in comparison with conventional management. DESIGN: Randomized controlled trial. SETTING: North Indian tertiary care hospital. PARTICIPANTS: Patients aged 40 to 60 years willing to sign the informed written consent were included, whereas cases with contraindications for neuraxial anesthesia were excluded. A total of 130 subjects undergoing robotic hysterectomy were divided into ERAS (n = 65) and conventional (non-ERAS) (n = 65) groups. INTERVENTIONS: Components of the ERAS protocol included preoperative counseling, carbohydrate loading, early removal of catheter, and early ambulation. Both groups underwent optimization of medical conditions, standardized anesthesia, and venous thromboembolism prophylaxis. MEASUREMENTS AND MAIN RESULTS: Outcome measures included length of hospital stay (LOHS), time to tolerance of diet, postoperative complications, readmission rates, and quality of life assessed by WHO-QOL BREF. Baseline characteristics were comparable between groups. ERAS group showed significantly lower docking time (4.82 ± 0.73 vs 5.31 ± 0.92 minutes), faster tolerance of diet (0.14 ± 0.35 vs 1.14 ± 0.35 days), and earlier resumption of ambulation (0.42 ± 0.5 vs 1.26 ± 0.44 days). Time for "fit for discharge" (1.43 ± 0.61 vs 2.97 ± 1.1 days) and LOHS (2.85 ± 1.09 vs 3.78 ± 1.29 days) were significantly lower in the ERAS group. Postoperative complications and readmission rates were comparable. Quality-of-life scores favored the ERAS group at postoperative days 1 and 30. CONCLUSION: The combination of ERAS and robotic surgery improves patient outcomes, shortens hospital stays, and enhances postoperative recovery without increasing complications. This research serves as a pioneering effort in assessing the impact of ERAS on robotic hysterectomy for benign indications, providing valuable insights for future multicentric studies and supporting the integration of ERAS protocols to enhance patient outcomes and quality of life.

Association of adherence to the enhanced recovery after surgery pathway and outcomes after laparoscopic total gastrectomy.

OBJECTIVE: The current study used a composite outcome to investigate whether applying the ERAS protocol would enhance the recovery of patients undergoing laparoscopic total gastrectomy (LTG). EXPOSURES: Laparoscopic total gastrectomy and perioperative interventions were the exposure. An ERAS clinical pathway consisting of 14 items was implemented and assessed. Patients were divided into either ERAS-compliant or non-ERAS-compliant group according the adherence above 9/14 or not. MAIN OUTCOMES AND MEASURES: The primary study outcome was a composite outcome called 'optimal postoperative recovery' with the definition as below: discharge within 6 days with no sever complications and no unplanned re-operation or readmission within 30 days postoperatively. Univariate logistic regression analysis and multivariate logistic regression analysis were used to model optimal postoperative recovery and compliance, adjusting for patient-related and disease-related characteristics. RESULTS: A total of 252 patients were included in this retrospective study, 129 in the ERAS compliant group and 123 in the non-ERAS-compliant group. Of these, 79.07% of the patients in ERAS compliant group achieved optimal postoperative recovery, whereas 61.79% of patients in non-ERAS-compliant group did (P = 0.0026). The incidence of sever complications was lower in the ERAS-compliant group (1.55% vs. 6.5%, P = 0.0441). No patients in ERAS compliant group had unplanned re-operation, whereas 5.69% (7/123) of patients in non-ERAS-compliant group had (p = 0.006). The median length of the postoperative hospital stay was shorter in the in the ERAS compliant group (5.51 vs. 5.68 days, P = 0.01). Both logistic (OR 2.01, 95% CI 1.21-3.34) and stepwise regression (OR 2.07, 95% CI 1.25-3.41) analysis showed that high overall compliance with the ERAS protocol facilitated optimal recovery in such patients. In bivariate analysis of compliance for patients who had an optimal postoperative recovery, carbohydrate drinks (p = 0.0196), early oral feeding (P = 0.0043), early mobilization (P = 0.0340), and restrictive intravenous fluid administration (P < 0.0001) were significantly associated with optimal postoperative recovery. CONCLUSIONS AND RELEVANCE: Patients with higher ERAS compliance (almost 70% of the accomplishment) suffered less severe postoperative complications and were more likely to achieve optimal postoperative recovery.

Impact of non-emergency surgical timing on postoperative recovery quality in mild or asymptomatic SARS-CoV-2 infected patients: a grouped cohort study.

OBJECTIVE: To explore the relationship between the timing of non-emergency surgery in mild or asymptomatic SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infected individuals and the quality of postoperative recovery from the time of confirmed infection to the day of surgery. METHODS: We retrospectively reviewed the medical records of 300 cases of mild or asymptomatic SARS-CoV-2 infected patients undergoing elective general anaesthesia surgery at Yijishan Hospital between January 9, 2023, and February 17, 2023. Based on the time from confirmed SARS-CoV-2 infection to the day of surgery, patients were divided into four groups: ≤2 weeks (Group A), 2-4 weeks (Group B), 4-6 weeks (Group C), and 6-8 weeks (Group D). The primary outcome measures included the Quality of Recovery-15 (QoR-15) scale scores at 3 days, 3 months, and 6 months postoperatively. Secondary outcome measures included postoperative mortality, ICU admission, pulmonary complications, postoperative length of hospital stay, extubation time, and time to leave the PACU. RESULTS: Concerning the primary outcome measures, the QoR-15 scores at 3 days postoperatively in Group A were significantly lower compared to the other three groups (P < 0.05), while there were no statistically significant differences among the other three groups (P > 0.05). The QoR-15 scores at 3 and 6 months postoperatively showed no statistically significant differences among the four groups (P > 0.05). In terms of secondary outcome measures, Group A had a significantly prolonged hospital stay compared to the other three groups (P < 0.05), while other outcome measures showed no statistically significant differences (P > 0.05). CONCLUSION: The timing of surgery in mild or asymptomatic SARS-CoV-2 infected patients does not affect long-term recovery quality but does impact short-term recovery quality, especially for elective general anaesthesia surgeries within 2 weeks of confirmed infection. Therefore, it is recommended to wait for a surgical timing of at least greater than 2 weeks to improve short-term recovery quality and enhance patient prognosis.

Prevalence, risk factors, natural history, and prognostic significance of Modic changes in the cervical spine: a comprehensive systematic review and meta-analysis of 12,754 participants.

OBJECTIVE: Modic changes (MCs) in the cervical spine are common, but remain an under-researched phenomenon, particularly regarding their prevalence, natural history, risk factors, and implications for surgical outcomes. This systematic review and meta-analysis endeavors to elucidate the multifactorial dimensions and clinical significance of cervical MCs. METHODS: Following PRISMA guidelines, a comprehensive systematic search was performed using Medline (via PubMed), EMBASE, Scopus, and Web of Science databases from their dates of inceptions to September 4, 2023. All identified articles were meticulously screened based on their relevance to our investigative criteria. Bias was assessed using quality assessments tools, including Quality in Prognosis Studies (QUIPS) and Newcastle-Ottawa Scale (NOS). Diverse datasets encompassing MCs prevalence, demographic influences, risk factors, cervical sagittal parameters, and surgical outcomes were extracted. Meta-analysis using both random and common effects model was used to synthesis the metadata. RESULTS: From a total of 867 studies, 38 met inclusion criteria and underwent full-text assessment. The overall prevalence of cervical MCs was 26.0% (95% CI: 19.0%, 34.0%), with a predominance of type 2 MCs (15% ; 95% CI: 0.10%, 0.23%). There was no significant difference between MCs and non-MCs in terms of neck pain (OR:3.09; 95% CI: 0.81, 11.88) and radicular pain (OR: 1.44; 95% CI: 0.64, 3.25). The results indicated a significantly higher mean age in the MC group (MD: 1.69 years; 95% CI: 0.29 years, 3.08 years). Additionally, smokers had 1.21 times the odds (95% CI: 1.01, 1.45) of a higher risk of developing MCs compared to non-smokers. While most cervical sagittal parameters remained unaffected, the presence of MCs indicated no substantial variation in pain intensity. However, a significant finding was the lower Japanese Orthopaedic Association (JOA) scores observed in MC patients at the 3-month (MD: -0.34, 95% CI: -0.62, -0.07) and 6-month (MD: -0.40, 95% CI: -0.80, 0.00) postoperative periods, indicating a prolonged recovery phase. CONCLUSION: This study found a predominant of type 2 MCs in the cervical spine. However, there was no significant mean difference between MCs and non-MC groups regarding neck pain and radicular pain. The results underscore the necessity for expansive, longitudinal research to elucidate the complexity of cervical MCs, particularly in surgical and postoperative contexts.

The impact of nursing interventions on the rehabilitation outcome of patients after lumbar spine surgery.

BACKGROUND: This study aimed to investigate the impact of nursing interventions on the rehabilitation outcomes of patients after lumbar spine surgery and to provide effective references for future postoperative care for patients undergoing lumbar spine surgery. METHODS: The study included two groups: a control group receiving routine care and an observation group receiving additional comprehensive nursing care. The comprehensive care encompassed postoperative rehabilitation, pain, psychological, dietary management, and discharge planning. The Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), Short-Form 36 (SF-36) Health Survey, self-rating depression scale (SDS) and self-rating anxiety scale(SAS) were used to assess physiological and psychological recovery. Blood albumin, haemoglobin, neutrophil counts, white blood cell counts, red blood cell counts, inflammatory markers (IL-6, IL-10, and IFN-γ) were measured, and the incidence of postoperative adverse reactions was also recorded. RESULTS: Patients in the observation group exhibited significantly improved VAS, ODI, SF-36, SDS and SAS scores assessments post-intervention compared to the control group (P < 0.05). Moreover, levels of IL-6, IL-10, and IFN-γ were more favorable in the observation group post-intervention (P < 0.05), indicating a reduction in inflammatory response. There was no significant difference in the incidence of postoperative adverse reactions between the groups (P > 0.05), suggesting that the comprehensive nursing interventions did not increase the risk of adverse effects. CONCLUSION: Comprehensive nursing interventions have a significant impact on the postoperative recovery outcomes of patients with LSS, alleviating pain, reducing inflammation levels, and improving the overall quality of patient recovery without increasing the patient burden. Therefore, in clinical practice, it is important to focus on comprehensive nursing interventions for patients with LSS to improve their recovery outcomes and quality of life.

Clinical application of a modified wiltse approach in middle and lower thoracic vertebrae: a case-control study of thoracic fracture patients.

BACKGROUND: The Wiltse approach has been extensively employed in thoracolumbar surgeries due to its minimal muscle damage. However, in the middle and lower thoracic spine, the conventional Wiltse approach necessitates the severance of the latissimus dorsi and trapezius muscles, potentially leading to muscular injury. Consequently, we propose a modified Wiltse approach for the middle and lower thoracic vertebrae, which may further mitigate muscular damage. METHODS: From May 2018 to April 2022, 60 patients with spinal fractures in the middle and lower thoracic vertebrae (T5-12) were enrolled in this study. Thirty patients underwent surgery using the modified Wiltse approach (Group A), while the remaining 30 patients received traditional posterior surgery (Group B). The observation indices included operation time, intraoperative blood loss, incision length, number of C-arm exposures, postoperative drainage, postoperative ambulation time, discharge time, as well as preoperative and postoperative Cobb's angle, percentage of anterior vertebral body height (PAVBH), visual analog scale (VAS) Score, and Oswestry disability index (ODI). RESULTS: Compared to the traditional posterior approach, the modified Wiltse approach demonstrated significant advantages in operation time, intraoperative blood loss, length of incision, postoperative ambulation time, postoperative drainage, and discharge time, as well as postoperative VAS and ODI scores. No significant differences were observed between the two groups in terms of number of C-arm exposures, postoperative Cobb's angle, or postoperative PAVBH. CONCLUSION: We propose a modification of the Wiltse approach for the middle and lower thoracic vertebral regions, which may further minimize muscular damage and facilitate the recovery of patients who have undergone surgery in the middle and lower thoracic vertebrae.

Effect of intraperitoneal infusion of ropivacaine combined with dexmedetomidine in patients undergoing total laparoscopic hysterectomy: a single-center randomized double-blinded controlled trial.

PURPOSE: To investigate the effect of intraperitoneal infusion of ropivacaine combined with dexmedetomidine and ropivacaine alone on the quality of postoperative recovery of patients undergoing total laparoscopic hysterectomy (TLH). METHODS: Female patients scheduled to undergo a TLH under general anesthesia at Fujian Maternity and Child Health Hospital were included. Before the end of pneumoperitoneum, patients were laparoscopically administered an intraperitoneal infusion of 0.25% ropivacaine 40 ml (R group) or 0.25% ropivacaine combined with 1 µg/kg dexmedetomidine 40 ml (RD group). The primary outcome was QoR-40, which was assessed before surgery and 24 h after surgery. Secondary outcomes included postoperative NRS scores, postoperative anesthetic dosage, the time to ambulation, urinary catheter removal, and anal exhaust. The incidence of dizziness, nausea, and vomiting was also analyzed. RESULTS: A total of 109 women were recruited. The RD group had higher QoR scores than the R group at 24 h after surgery (p < 0.05). Compared with the R group, NRS scores in the RD group decreased at 2, 6, 12, and 24 h after surgery (all p < 0.05). In the RD group, the time to the first dosage of postoperative opioid was longer and the cumulative and effective times of PCA compression were less than those in the R group (all p < 0.05). Simultaneously, the time to ambulation (p = 0.033), anal exhaust (p = 0.002), and urethral catheter removal (p = 0.018) was shortened in the RD group. The RD group had a lower incidence of dizziness, nausea, and vomiting (p < 0.05). CONCLUSION: Intraperitoneal infusion of ropivacaine combined with dexmedetomidine improved the quality of recovery in patients undergoing TLH.

Enhanced recovery after surgery versus conventional postoperative care in patients undergoing hysterectomy: a systematic review and meta-analysis.

PURPOSE: Hysterectomy is a common gynecological surgery associated with significant postoperative discomfort and extended hospital stays. Enhanced recovery after surgery (ERAS), a multidisciplinary approach, has emerged as a strategy aimed at improving perioperative outcomes and promoting faster patient recovery and satisfaction. This meta-analysis aimed to evaluate the impact of ERAS protocols on clinical outcomes, such as hospital stay length, readmission rates, and postoperative complications, in patients undergoing gynecological hysterectomy. METHODS: Following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, a systematic review and meta-analysis were conducted. Databases including PubMed, Embase, and Cochrane library were searched for relevant studies published up to January 31, 2023. A total of seventeen studies were selected based on predefined eligibility and exclusion criteria. Meta-analysis was carried out using a random-effects model with the STATA SE 14.0 software, focusing on outcomes like length of hospital stay, postoperative complications, and readmission rates. RESULTS: ERAS protocols significantly reduced the length of hospital stays and incidence of postoperative complications such as ileus, without increasing readmission rates or the level of patient-reported pain. Notable heterogeneity was observed among included studies, attributed to the variation in patient populations and the specificity of the documented study protocols. CONCLUSION: The findings underscore the effectiveness of ERAS protocols in enhancing recovery trajectories in gynecological hysterectomy patients. This reinforces the imperative for broader, standardized adoption of ERAS pathways as an evidence-based approach, fostering a safer and more efficient perioperative care paradigm.
