Maternal obesity and metabolic (dysfunction) associated fatty liver disease in pregnancy: a comprehensive narrative review

INTRODUCTION

Obesity and metabolic-associated fatty liver disease (MAFLD) during pregnancy constitute significant problems for routine antenatal care, with increasing prevalence globally. Similar to obesity, MAFLD is associated with a higher risk for maternal complications (e.g. pre-eclampsia and gestational diabetes) and long-term adverse health outcomes for the offspring. However, MAFLD during pregnancy is often under-recognized, with limited management/treatment options.

AREAS COVERED

PubMed/MEDLINE, EMBASE, and Scopus were searched based on a search strategy for obesity and/or MAFLD in pregnancy to identify relevant papers up to 2024. This review summarizes the pertinent evidence on the relationship between maternal obesity and MAFLD during pregnancy. Key mechanisms implicated in the underlying pathophysiology linking obesity and MAFLD during pregnancy (e.g. insulin resistance and dysregulated adipokine secretion) are highlighted. Moreover, a diagnostic approach for MAFLD diagnosis during pregnancy and its complications are presented. Finally, promising relevant areas for future research are covered.

EXPERT OPINION

Research progress regarding maternal obesity, MAFLD, and their impact on maternal and fetal/offspring health is expected to improve the relevant diagnostic methods and lead to novel treatments. Thus, routine practice could apply more personalized management strategies, incorporating individualized algorithms with genetic and/or multi-biomarker profiling to guide prevention, early diagnosis, and treatment.

Safety and effectiveness of tunneled peripherally inserted central catheters versus conventional PICC in adult cancer patients

OBJECTIVES

This study aimed to compare the safety and effectiveness of tunneled peripherally inserted central catheters (T-PICC) vs. conventional PICCs (C-PICC) in adult cancer patients.

METHODS

A multicentre randomized controlled trial was conducted between April 2021 and January 2022 in seven hospitals in China. 564 participants were randomly assigned to T-PICC or C-PICC. These data were collected and compared: the baseline characteristics and catheterization-related characteristics, periprocedural complications, and long-term complications.

RESULTS

Five-hundred fifty-three participants (aged, 52.6 ± 12.3 years; female, 39.1%) were ultimately analyzed. No significant differences in periprocedural complications were found between the T-PICC and C-PICC groups (all p > 0.05). Compared with C-PICC, T-PICC significantly reduced the incidence of long-term complications (26.4% vs. 39.9%, p < 0.001). Specifically, reduced complications were found in central line-associated bloodstream infection (1.8% vs. 5.1%, p = 0.04), thrombosis (1.1% vs. 4.0%, p = 0.03), catheter dislodgement (4.7% vs. 10.1%, p = 0.01), non-infectious oozing (17.3% vs. 28.6%, p = 0.002), local infection (3.6% vs. 7.6%, p = 0.04), skin irritation (6.1% vs. 10.9%, p = 0.046), and reduced unplanned catheter removal (2.2% vs. 7.2%, p = 0.005). No significant differences were found between T-PICC and C-PICC regarding catheter occlusion (6.5% vs. 5.8%, p = 0.73) or skin damage (2.2% vs. 2.9%, p = 0.58).

CONCLUSION

T-PICC is safe and effectively reduces long-term complications.

CLINICAL RELEVANCE STATEMENT

The tunneled technique is effective in reducing PICC-related long-term complications. Thus, it is recommended for cancer patients at high risk of PICC-related complications.

TRIAL REGISTRATION

The registration number on https://www.chictr.org.cn/ is ChiCTR2100044632. The name of the trial registry is "A multicenter randomized controlled study of clinical use of tunneled vs. non-tunneled PICC".

KEY POINTS

Cather-related complications are associated with the technique of catheterization. Compared with conventional PICC, tunneled PICC reduced catheter-related long-term complications. Tunneled PICC placement provides an alternative catheterization method for cancer patients.

Enhanced Recovery After Surgery Guidelines and Hospital Length of Stay, Readmission, Complications, and Mortality: A Meta-Analysis of Randomized Clinical Trials

Importance

A comprehensive review of the evidence exploring the outcomes of enhanced recovery after surgery (ERAS) guidelines has not been completed.

Objective

To evaluate if ERAS guidelines are associated with improved hospital length of stay, hospital readmission, complications, and mortality compared with usual surgical care, and to understand differences in estimates based on study and patient factors.

Data Sources

MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Central were searched from inception until June 2021.

Study Selection

Titles, abstracts, and full-text articles were screened by 2 independent reviewers. Eligible studies were randomized clinical trials that examined ERAS-guided surgery compared with a control group and reported on at least 1 of the outcomes.

Data Extraction and Synthesis

Data were abstracted in duplicate using a standardized data abstraction form. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Risk of bias was assessed in duplicate using the Cochrane Risk of Bias tool. Random-effects meta-analysis was used to pool estimates for each outcome, and meta-regression identified sources of heterogeneity within each outcome.

Main Outcome and Measures

The primary outcomes were hospital length of stay, hospital readmission within 30 days of index discharge, 30-day postoperative complications, and 30-day postoperative mortality.

Results

Of the 12 047 references identified, 1493 full texts were screened for eligibility, 495 were included in the systematic review, and 74 RCTs with 9076 participants were included in the meta-analysis. Included studies presented data from 21 countries and 9 ERAS-guided surgical procedures with 15 (20.3%) having a low risk of bias. The mean (SD) Reporting on ERAS Compliance, Outcomes, and Elements Research checklist score was 13.5 (2.3). Hospital length of stay decreased by 1.88 days (95% CI, 0.95-2.81 days; I2 = 86.5%; P < .001) and the risk of complications decreased (risk ratio, 0.71; 95% CI, 0.59-0.87; I2 = 78.6%; P < .001) in the ERAS group. Risk of readmission and mortality were not significant.

Conclusions and Relevance

In this meta-analysis, ERAS guidelines were associated with decreased hospital length of stay and complications. Future studies should aim to improve implementation of ERAS and increase the reach of the guidelines.

Poland's first vascular access team 3-year analysis: Insights and learnings

BACKGROUND

During the COVID-19 pandemic, Poland saw a surge in interest in midline catheters (MCs) and Long Peripheral Catheters (LPCs) for intravenous therapy. Before this, MCs were not extensively utilised in the country, and there was no formally established Polish vascular access team. MCs, which have been used for years in many countries, are now becoming increasingly common in Poland. This study aimed to analyse the use of MCs in a 3-year perspective of their introduction in daily clinical practice based on a nurse-led Vascular Access Team (VAT).

METHODS

The records of adult patients who received intravenous therapy with 727 MCs and 293 LPCs from January 2021 to December 2023 at the University Clinical Centre of the Medical University of Warsaw were analysed.

RESULTS

The main indication for cannulation was expected intravenous therapy over 5 days (81.66%, n = 833), of which 71.37% (n = 728) of patients in this group had concomitant difficult intravenous access (DIVA). Over 6 years, centrally inserted central catheters (CICCs) inserted due to DIVA were reduced from n = 108 in 2017 to n = 18 in 2023. The end of intravenous therapy was the reason for the removal of 64.6% of catheters (n = 659), including death and switch to CICCs as well. Complications leading to premature removal accounted for 31.2%, such as: occlusion (14.6%), patient self-removal (7.1%) and thrombosis (3.43%).

CONCLUSIONS

The introduction of MCs as a possible option for peripheral venous access reduces the use of CVCs. Developing MCs programmes should be based on investing in staff competencies, which increases success rates. The nurses and physicians should be trained in infusion care to achieve better results in the use of MCs and LPCs. Increasing the competence of nurses in Poland is necessary for the implementation of full-service and top-level functioning of VAT.

Preoperative depression and anxiety associated with younger age and receipt of immediate breast reconstruction

BACKGROUND

As survivorship for breast cancer continues to improve, emphasis of care falls upon improving patients' quality of life. Understanding physical and mental health in the preoperative period is needed to aid surgical decision making and improve patient experience.

METHODS

Consecutive patients awaiting total mastectomy (TM), TM with immediate breast reconstruction (IBR) and breast conserving surgery (BCS) were prospectively recruited. Scores for PHQ-9, GAD-7, Breast-Q, EQ5D(5L), PEG were collected preoperatively. Association was measured with multivariate analyses.

RESULTS

477 participants (374 BSC, 46 ​TM, 84 IBR) were included. Younger patients and those choosing IBR reported worse depression and anxiety symptoms. Clinical tumor features did not affect patient reported outcomes. Higher Breast-Q scores were seen with BCS and lower scores with TM.

CONCLUSIONS

Patients scheduled for IBR and younger patients reported worse symptoms of depression and anxiety, regardless of clinical features. This will help with surgical decision making and identify patients in need for additional perioperative supports.

Effectiveness of WeChat-assisted preoperative education to reduce perioperative anxiety in breast cancer patients: a prospective randomized controlled study protocol

BACKGROUND

Breast cancer is the most prevalent cancer among women globally, and surgical procedures continue to be the primary treatment. However, over 50% of patients experience preoperative anxiety due to the unknown and fear associated with surgery. Although drug therapy is commonly used to address this anxiety, its side effects have led to a heated debate regarding its effectiveness. Consequently, non-pharmacological therapies, such as preoperative education, have emerged as an alternative approach to alleviate anxiety. WeChat, a widely popular social media platform, offers a public platform that can potentially be utilized for effective preoperative education. This study aims to evaluate the use of WeChat public platform as a tool for preoperative education in patients undergoing breast surgery.

METHODS

This is a prospective, randomized, and controlled trial will involve 392 adult women scheduled for breast cancer resection. Participants will be randomly assigned to either the WeChat education group or the regular group. In addition to regular preoperative visits, the WeChat education group will also watch science videos through the WeChat public platform. The regular group will only receive education from ward nurses during preoperative visits. The primary outcome measure will be the incidence of preoperative anxiety, defined by scores of the State Anxiety Inventory (SAI) exceeding 40 points. Secondary outcome measures include the incidence of severe anxiety (SAI > 44) on the day before surgery, incidence of anxiety 72 h after surgery, incidence of severe anxiety 72 h after surgery, NRS scores for pain at rest and during activity 24, 48, and 72 h after surgery, incidence of nausea and vomiting within 24 h after surgery, subjective sleep score at 1 week postoperatively, quality of life QoR-15 scores at 1 and 3 months postoperatively, incidence of chronic pain at 3 months postoperatively, bowel function recovery, length of hospital stay, and hospitalization expenses.

DISCUSSION

This is the first clinical trial to investigate the use of WeChat public platform for delivering preoperative education on perioperative anxiety in breast cancer patients. By utilizing the renowned WeChat public platform, our study aims to improve patient outcomes by providing video education that explains the disease, surgery, and anesthesia in a more accessible manner, thereby reducing the incidence of perioperative anxiety. If our hypothesis is confirmed, this non-pharmacological approach can be universally acknowledged as a cost-effective and practical method in clinical care. Its application can also be extended to other medical fields beyond breast cancer.

Peri-operative individually tailored psychological intervention in breast cancer patients improves psychological indices and molecular biomarkers of metastasis in excised tumors

Perioperative stress and inflammatory signaling can invigorate pro-metastatic molecular processes in patients' tumors, potentially worsening long-term survival. Yet, it is unknown whether pre-operative psychotherapeutic interventions can attenuate such effects. Herein, three weeks before surgery, forty women diagnosed with stage I-III invasive ductal/lobular breast carcinoma were randomized to a 6-week one-on-one psychological intervention (6 meetings with a medical psychologist and bi-weekly phone calls) versus standard nursing-staff-attention. The intervention protocol was individually tailored based on evaluation of patients' emotional, cognitive, physiological, and behavioral stress response-patterns, and also included psychoeducation regarding medical treatments and recruitment of social support. Resected primary tumors were subjected to whole-genome RNA sequencing and bioinformatic analyses, assessing a priori hypothesized cancer-relevant molecular signatures. Self-report questionnaires (BSI-18, Hope-18, MSPSS, and a stress-scale) were collected three (T1) and one (T2) week before surgery, a day before (T3) and after (T4) surgery, and three weeks (T5) and 3-months (T6) following surgery. The intervention reduced distress (GSI), depression, and somatization scores (BSI-18: p < 0.01, p < 0.05, p < 0.05; T5 vs. T1). Additionally, tumors from treated patients (vs. controls) showed: (i) decreased activity of transcription control pathways involved in adrenergic and glucocorticoid signaling (CREB, GR) (p < 0.001), pro-inflammatory signaling (NFkB) (p < 0.01), and pro-malignant signaling (ETS1, STAT and GATA families) (p < 0.001, p < 0.01, p < 0.005); (ii) increased M1 macrophage polarization (p < 0.05), and CD4+ T cell activity (p < 0.01); and an unexpected increase in epithelial-to-mesenchymal-transition (EMT) signature (p < 0.005). This is the first randomized controlled trial to show beneficial effects of a psychological perioperative intervention on tumor pro-metastatic molecular biomarkers.

Brachial Tunneled Peripherally Inserted Central Catheters and the Risk of Catheter Complications: A Systematic Review and Meta-Analysis

INTRODUCTION

Situations involving increased workloads and stress (i.e., the COVID-19 pandemic) underline the need for healthcare professionals to minimize patient complications. In the field of vascular access, tunneling techniques are a possible solution. This systematic review and meta-analysis aimed to compare the effectiveness of tunneled Peripherally Inserted Central Catheters (tPICCs) to conventional Peripherally Inserted Central Catheters (cPICCs) in terms of bleeding, overall success, procedural time, and late complications.

METHODS

Randomized controlled trials without language restrictions were searched using PUBMED®, EMBASE®, EBSCO®, CINAHL®, and the Cochrane Controlled Clinical Trials Register from August 2022 to August 2023. Five relevant papers (1238 patients) were included.

RESULTS

There were no significant differences in overall success and nerve or artery injuries between the two groups (p = 0.62 and p = 0.62, respectively), although cPICCs caused slightly less bleeding (0.23 mL) and had shorter procedural times (2.95 min). On the other hand, tPICCs had a significantly reduced risk of overall complications (p < 0.001; RR0.41 [0.31-0.54] CI 95%), catheter-related thrombosis (p < 0.001; RR0.35 [0.20-0.59] IC 95%), infection-triggering catheter removal (p < 0.001; RR0.33 [0.18-0.61] IC 95%), wound oozing (p < 0.001; RR0.49 [0.37-0.64] IC 95%), and dislodgement (p < 0.001; RR0.4 [0.31-0.54] CI 95%).

CONCLUSIONS

The tunneling technique for brachial access appears to be safe concerning intra-procedural bleeding, overall success, and procedural time, and it is effective in reducing the risk of late complications associated with catheterization.

Clinical observation of gastrointestinal function recovery in patients after hepatobiliary surgery

BACKGROUND

The liver is an important metabolic and digestive organ in the human body, capable of producing bile, clotting factors, and vitamins.

AIM

To investigate the recovery of gastrointestinal function in patients after hepatobiliary surgery and identify effective rehabilitation measures.

METHODS

A total of 200 patients who underwent hepatobiliary surgery in our hospital in 2022 were selected as the study subjects. They were divided into a control group and a study group based on the extent of the surgery, with 100 patients in each group. The control group received routine treatment, while the study group received targeted interventions, including early enteral nutrition support, drinking water before gas discharge, and large bowel enema, to promote postoperative gastrointestinal function recovery. The recovery of gastrointestinal function was compared between the two groups.

RESULTS

Compared with the control group, patients in the study group had better recovery of bowel sounds and less accumulation of fluids in the liver bed and gallbladder fossa (P < 0.05). They also had shorter time to gas discharge and first meal (P < 0.05), higher overall effective rate of gastrointestinal function recovery (P < 0.05), and lower incidence of postoperative complications (P < 0.05).

CONCLUSION

Targeted nursing interventions (early nutritional support, drinking water before gas discharge, and enema) can effectively promote gastrointestinal function recovery in patients undergoing hepatobiliary surgery and reduce the incidence of complications, which is worthy of promotion.

Passive sweat wearable: A new paradigm in the wearable landscape toward enabling "detect to treat" opportunities

Growing interest over recent years in personalized health monitoring coupled with the skyrocketing popularity of wearable smart devices has led to the increased relevance of wearable sweat-based sensors for biomarker detection. From optimizing workouts to risk management of cardiovascular diseases and monitoring prediabetes, the ability of sweat sensors to continuously and noninvasively measure biomarkers in real-time has a wide range of applications. Conventional sweat sensors utilize external stimulation of sweat glands to obtain samples, however; this stimulation influences the expression profile of the biomarkers and reduces the accuracy of the detection method. To address this limitation, our laboratory pioneered the development of the passive sweat sensor subfield, which allowed for our progress in developing a sweat chemistry panel. Passive sweat sensors utilize nanoporous structures to confine and detect biomarkers in ultra-low sweat volumes. The ability of passive sweat sensors to use smaller samples than conventional sensors enable users with sedentary lifestyles who perspire less to benefit from sweat sensor technology not previously afforded to them. Herein, the mechanisms and strategies of current sweat sensors are summarized with an emphasis on the emerging subfield of passive sweat-based diagnostics. Prospects for this technology include discovering new biomarkers expressed in sweat and expanding the list of relevant detectable biomarkers. Moreover, the accuracy of biomarker detection can be enhanced with machine learning using prediction algorithms trained on clinical data. Applying this machine learning in conjunction with multiplex biomarker detection will allow for a more holistic approach to trend predictions.

Nurse-Administered Propofol Sedation Training Curricula and Propofol Administration in Digestive Endoscopy Procedures: A Scoping Review of the Literature

Although efficacy and safety of nonanesthesiologist administration of propofol and nurse-administered propofol sedation practices have been amply demonstrated in patients at low American Society of Anesthesiologists physical status risk, they are still severely limited. To date, it is quite difficult to find a protocol or a shared training program. The aim of the study was to verify requirements, types of training, and operating methods described in the literature for the administration of propofol by a nurse. A scoping review of the literature was conducted in accordance with the PRISMA-ScR guidelines and in line with Arksey and O'Malley's framework, within four main databases of biomedical interest: MEDLINE, CINAHL, Scopus, and Web of Science. We selected studies published during the last 20 years, including only nurses not trained in anesthesia. Seventeen articles were eligible. Despite the differences between the training and administration methods, efficacy and safety of deep sedation managed by trained nurses were comparable, just like when sedation was administered by certified registered nurse anesthetists. Training programs have been investigated in detail by only a small number of studies, although its efficacy and safety have been widely demonstrated. It is important, then, to collect evidence that allows developing of unified international guidelines for training methods to offer safe and cost-effective quality sedation.

The Total Intra Venous Anesthesia Effect Versus Volatile Anesthesia, on Stress and Pain Levels, in Patients Undergoing Breast Reconstruction in Ambulatory Surgery Center Total Intra Venous Anesthesia Protocol and Stress Response

AIM

To compare pain and stress response through cortisol and DHEA levels, implementing. Total intra venous anesthesia (TIVA) versus general anesthesia with volatile anesthetics (VOL).

DESIGN

This is a prospective randomized correlation study with consecutive measurements.

METHODS

In an ambulatory surgical center from October of 2019 to August of 2020, patients who underwent breast reconstruction with autologous fat grafting were randomized into 2 groups. Patients in the TIVA group (n = 23) received intravenous anesthesia and those in the VOL group (n = 23) received volatile anesthesia (desflurane). Demographic, anthropometric and clinical data were recorded. Arterial systolic (SP) and diastolic (DP) blood pressure, heart rate and oxygen saturation were recorded. Pain and stress levels were evaluated through salivary cortisol and DHEA levels at 4 different time points: T0) 1 hour before induction, T1) during the induction, T2) during anesthesia maintenance, and T3) in recovery phase. Statistical analysis was performed with SPSS 25.0 at significant level α = .05.

FINDINGS

There were no statistically significant differences between the 2 groups regarding demographic features. Interestingly that there was a statistically significant difference in the vital sign monitoring where patients in the TIVA group reported with higher levels of SP(T2) and DP (T2), whilst DHEA (T1) levels was correlated positively with patient's age and cortisol (T1) levels and negatively with DP (T3).

CONCLUSIONS

This study supports the use of TIVA as a safe and effective option for anesthesia in patients undergoing breast reconstruction with autologous fat grafting.

Implementation of Tunneled Peripherally Inserted Central Catheters Placement in Cancer Patients: A Randomized Multicenter Study

This study sought to evaluate the impact of the subcutaneous tunneling technique on peripherally inserted central catheter (PICC) placement. We randomized 694 patients who needed PICC placement to either the tunneled PICCs (experimental group) or the non-tunneled PICCs (control group) from August to December 2021. The cumulative frequency of complications was assessed as the primary outcome. Secondary outcomes comprised of the amount of bleeding, catheter insertion time, self-reported pain score, and one-puncture success rate. After 6 months of follow-up, the tunneled PICCs group showed a significant decrease in the frequency of total complications, especially in infection (3.0% vs. 7.1%, p = .021) and catheter-related thrombosis (3.3% vs. 8.3%, p = .008), although approximately 0.5 ml bleeding and 3.5 min time were increased. This randomized multicenter study supports the efficacy of subcutaneous tunneling technology in reducing PICC-related complications, enhancing patient comfort, and encouraging using subcutaneous tunneling technology for PICC placement.

Giant lipoma in the Retzius space resected under laparoscopy: A case report

Lipoma is a common type of benign soft tissue tumor that can occur in the shoulders, neck and back, in addition to other body parts. The Retzius space is a small anatomical space between the pubic symphysis and the bladder located extraperitoneally and filled with loose fatty connective tissue. Giant lipomas are rare in the Retzius space. A 61-year-old Chinese male arrived at Beijing Yanhua Hospital (Beijing, China) due to frequent urination, and CT scan images of the lower abdomen observed a large pelvic mass and left inguinal hernia. Preoperative clinical manifestations and auxiliary examination suggested that the tumor originated from the urinary bladder wall. The maximum tumor diameter was ~25 cm and abdominal pressure was increased. Therefore, laparoscopic pelvic tumor resection combined with inguinal hernia repair was attempted. Intraoperatively, the tumor was found to originate from the Retzius space and the postoperative pathological diagnosis was lipoma. The present case report may serve as a reference for minimally invasive treatment of this type of rare disease in future.

Simulation of Image-Guided Microwave Ablation Therapy Using a Digital Twin Computational Model

Emerging computational tools such as healthcare digital twin modeling are enabling the creation of patient-specific surgical planning, including microwave ablation to treat primary and secondary liver cancers. Healthcare digital twins (DTs) are anatomically one-to-one biophysical models constructed from structural, functional, and biomarker-based imaging data to simulate patient-specific therapies and guide clinical decision-making. In microwave ablation (MWA), tissue-specific factors including tissue perfusion, hepatic steatosis, and fibrosis affect therapeutic extent, but current thermal dosing guidelines do not account for these parameters. This study establishes an MR imaging framework to construct three-dimensional biophysical digital twins to predict ablation delivery in livers with 5 levels of fat content in the presence of a tumor. Four microwave antenna placement strategies were considered, and simulated microwave ablations were then performed using 915 MHz and 2450 MHz antennae in Tumor Naïve DTs (control), and Tumor Informed DTs at five grades of steatosis. Across the range of fatty liver steatosis grades, fat content was found to significantly increase ablation volumes by approximately 29-l42% in the Tumor Naïve and 55-60% in the Tumor Informed DTs in 915 MHz and 2450 MHz antenna simulations. The presence of tumor did not significantly affect ablation volumes within the same steatosis grade in 915 MHz simulations, but did significantly increase ablation volumes within mild-, moderate-, and high-fat steatosis grades in 2450 MHz simulations. An analysis of signed distance to agreement for placement strategies suggests that accounting for patient-specific tumor tissue properties significantly impacts ablation forecasting for the preoperative evaluation of ablation zone coverage.

One-lung ventilation with a bronchial blocker in thoracic patients

BACKGROUND

Lung isolation is a technique used in a multitude of surgeries to ensure single-lung ventilation with collapse of the contralateral lung, as to achieve improved access and visualization of relevant anatomical structures. Despite being accepted and having favorable outcomes, bronchial blockers (BBs) are not to this day the main device of choice among anaesthesiologists.

METHODS

In this retrospective and descriptive study, we analyzed the safety and efficacy of a BB in all types of thoracic surgeries in our centre between 2015 and 2022, excluding patients with massive hemoptysis or empyema, or who had undergone a prior pneumonectomy.

RESULTS

One hundred and thirty-four patients were intervened due to lung cancer (67.9%), respiratory disease (23.9%), and non-respiratory disease (8.2%) undergoing lung surgeries (65.7%), pleural and mediastinal surgeries (29.9%), chest wall surgeries (3.0%) and other surgeries (1.5%). In most cases, lung collapse was considered excellent (63.9%) or good (33.1%) with only 4 cases (3.0%) of poor lung collapse. More than 90% of patients did not present intraoperative or immediate postoperative complications. No statistically significant differences were found between lung collapse and the demographic, clinical or BB-related variables (p > 0.05). However, we found a significatively higher proportion of excellent lung collapses in VATS surgeries and lateral decubitus positioning, as well as a significatively less proportion of poor lung collapses (p < 0.05). Moreover, there was a significantly higher proportion of excellent lung collapses when the BB was placed in the left bronchus (p < 0.05).

CONCLUSIONS

With these results, in our experience BBs constitute an effective alternative, capable of achieving pulmonary collapse in all kinds of thoracic procedures with satisfactory safety rates due to their minimal complications.

Establishment and Validation of the LI-RADS Morphologic Type II Hepatocellular Carcinoma Early Recurrence Risk Scoring System

BACKGROUND

Tumor morphology links to early recurrence of hepatocellular carcinoma. Controversy exists regarding the recurrence risk of Liver Imaging Reporting and Data System morphologic Type II hepatocellular carcinoma. This study aims to explore risk factors for early recurrence of Type II hepatocellular carcinoma.

METHODS

Retrospective analysis of hepatocellular carcinoma patients who underwent curative resection and preoperative contrast-enhanced MRI from June 2016 to June 2020. Our patients formed the development set, and hepatocellular carcinoma patients from the TCIA database served as validation. Univariable and multivariable Cox regression identified independent risk factors for early recurrence. A risk scoring system was established for risk stratification, and an early recurrence prediction model was developed and validated.

RESULTS

95 Type II hepatocellular carcinoma patients were in the development set, and 29 cases were in the validation set. Early recurrence rates were 33.7% and 37.9%, respectively. Multivariate analysis revealed age, histological grade, AFP, and intratumoral hemorrhage as independent risk factors for early recurrence. The model's diagnostic performance for early recurrence was AUC = 0.817 in the development set. A scoring system classified patients into low-risk (scores ≤ 3) and high-risk (scores > 3) groups. The high-risk group had significantly lower recurrence-free survival (40.0% vs 73.2%, P = 0.001), consistent with the validation set (25.0% vs 73.3%, P = 0.028).

CONCLUSIONS

The risk scoring system demonstrated excellent discrimination and predictive ability, aiding clinicians in assessing early recurrence risk and identifying high-risk individuals effectively.

A GAVeCeLT bundle for PICC-port insertion: The SIP-Port protocol

In the last decade, a new type of brachial port has been introduced in clinical practice, the so-called "PICC-port." This is a brachial port, but inserted according to the methodologies and technologies currently adopted for the insertion of peripherally inserted central catheters (PICCs). Several studies have shown that PICC-port insertion is safe, not associated with any relevant immediate or early complication, and that the expected incidence of late complications is significantly lower if compared to "traditional" brachial ports (i.e. inserted without ultrasound guidance). Furthermore, PICC-ports yield excellent esthetic results and are associated with optimal patient compliance. This paper describes an insertion bundle-developed by GAVeCeLT, the Italian Group of Long Term Venous Access Devices, and nicknamed "SIP-Port" (Safe Insertion of PICC-Ports)-which consists of few evidence-based strategies aiming to further minimize all immediate, early, or late complications potentially associated with PICC-port insertion. Also, this insertion bundle has been developed for the purpose of defining more closely the differences between a traditional brachial port and a PICC-port. The SIP-Port bundle is currently adopted by all training courses on PICC-port insertion held by GAVeCeLT. It includes eight steps: (1) preprocedural ultrasound assessment utilizing the RaPeVA (Rapid Peripheral Venous Assessment) protocol; (2) appropriate skin antiseptic technique and maximal barrier precautions; (3) choice of appropriate vein, in terms of caliber and site; (4) clear identification of the median nerve and of the brachial artery during the venipuncture; (5) ultrasound-guided puncture and cannulation of the vein; (6) ultrasound-guided tip navigation; (7) intra-procedural assessment of tip location by intracavitary ECG or by trans-thoracic echocardiography; (8) appropriate creation and closure of the subcutaneous pocket.

Impact of interventions to improve recovery of older adults following planned hospital admission on quality-of-life following discharge: linked-evidence synthesis

Objectives

To understand the impact of multicomponent interventions to improve recovery of older adults following planned hospital treatment, we conducted two systematic reviews, one of quantitative and one of qualitative evidence, and an overarching synthesis. These aimed to: • understand the effect of multicomponent interventions which aim to enhance recovery and/or reduce length of stay on patient-reported outcomes and health and social care utilisation • understand the experiences of patients, carers and staff involved in the delivery of interventions • understand how different aspects of the content and delivery of interventions may influence patient outcomes.

Review methods

We searched bibliographic databases including MEDLINE ALL, Embase and the Health Management Information Consortium, CENTRAL, and Cumulative Index to Nursing and Allied Health Literature and Allied and Complementary Medicine Database, conducted forward and backward citation searching and examined reference lists of topically similar qualitative reviews. Bibliographic database searches were completed in May/June 2021 and updated in April 2022. We sought primary research from high-income countries regarding hospital inpatients with a mean/median age of minimum 60 years, undergoing planned surgery. Patients experienced any multicomponent hospital-based intervention to reduce length of stay or improve recovery. Quantitative outcomes included length of stay and any patient-reported outcome or experience or service utilisation measure. Qualitative research focused on the experiences of patients, carers/family and staff of interventions received. Quality appraisal was undertaken using the Effective Public Health Practice Project Quality Assessment Tool or an adapted version of the Wallace checklist. We used random-effects meta-analysis to synthesise quantitative data where appropriate, meta-ethnography for qualitative studies and qualitative comparative analysis for the overarching synthesis.

Results

Quantitative review: Included 125 papers. Forty-nine studies met criteria for further synthesis. Enhanced recovery protocols resulted in improvements to length of stay, without detriment to other outcomes, with minimal improvement in patient-reported outcome measures for patients admitted for lower-limb or colorectal surgery. Qualitative review: Included 43 papers, 35 of which were prioritised for synthesis. We identified six themes: 'Home as preferred environment for recovery', 'Feeling safe', 'Individualisation of structured programme', 'Taking responsibility', 'Essential care at home' and 'Outcomes'. Overarching synthesis: Intervention components which trigger successful interventions represent individualised approaches that allow patients to understand their treatment, ask questions and build supportive relationships and strategies to help patients monitor their progress and challenge themselves through early mobilisation.

Discussion

Interventions to reduce hospital length of stay for older adults following planned surgery are effective, without detriment to other patient outcomes. Findings highlight the need to reconsider how to evaluate patient recovery from the perspective of the patient. Trials did not routinely evaluate patient mid- to long-term outcomes. Furthermore, when they did evaluate patient outcomes, reporting is often incomplete or conducted using a narrow range of patient-reported outcome measures or limited through asking the wrong people the wrong questions, with lack of longer-term evaluation. Findings from the qualitative and overarching synthesis will inform policy-making regarding commissioning and delivering services to support patients, carers and families before, during and after planned admission to hospital.

From clinical variables to multiomics analysis: a margin morphology-based gross classification system for hepatocellular carcinoma stratification

OBJECTIVE

Selecting interventions for patients with solitary hepatocellular carcinoma (HCC) remains a challenge. Despite gross classification being proposed as a potential prognostic predictor, its widespread use has been restricted due to inadequate studies with sufficient patient numbers and the lack of established mechanisms. We sought to investigate the prognostic impacts on patients with HCC of different gross subtypes and assess their corresponding molecular landscapes.

DESIGN

A prospective cohort of 400 patients who underwent hepatic resection for solitary HCC was reviewed and analysed and gross classification was assessed. Multiomics analyses were performed on tumours and non-tumour tissues from 49 patients to investigate the mechanisms underlying gross classification. Inverse probability of treatment weight (IPTW) was used to control for confounding factors.

RESULTS

Overall 3-year survival rates varied significantly among the four gross subtypes (type I: 91%, type II: 80%, type III: 74.6%, type IV: 38.8%). Type IV was found to be independently associated with poor prognosis in both the entire cohort and the IPTW cohort. The four gross subtypes exhibited three distinct transcriptional modules. Particularly, type IV tumours exhibited increased angiogenesis and immune score as well as decreased metabolic pathways, together with highest frequency of TP53 mutations. Patients with type IV HCC may benefit from adjuvant intra-arterial therapy other than the other three subtypes. Accordingly, a modified trichotomous margin morphological gross classification was established.

CONCLUSION

Different gross types of HCC showed significantly different prognosis and molecular characteristics. Gross classification may aid in development of precise individualised diagnosis and treatment strategies for HCC.

Impact of enhanced recovery pathways on patient-reported outcomes after abdominal surgery: a systematic review

INTRODUCTION

Evidence supports that enhanced recovery pathways (ERPs) reduce length of stay and complications; however, these measures may not reflect the perspective of patients who are the main stakeholders in the recovery process. This systematic review aimed to appraise the evidence regarding the impact of ERPs on patient-reported outcomes (PROs) after abdominal surgery.

METHODS

Five databases (Medline, Embase, Biosis, Cochrane, and Web of Science) were searched for randomized controlled trials (RCTs) addressing the impact of ERPs on PROs after abdominal surgery. We focused on distinct periods of recovery: early (within 7 days postoperatively) and late (beyond 7 days). Risk of bias was assessed using Cochrane's RoB 2.0. Results were appraised descriptively as heterogeneity hindered meta-analysis. Certainty of evidence was evaluated using GRADE.

RESULTS

Fifty-six RCTs were identified [colorectal (n = 18), hepatopancreaticobiliary (HPB) (n = 11), upper gastrointestinal (UGI) (n = 10), gynecological (n = 7), urological (n = 7), general surgery (n = 3)]. Most trials had 'some concerns' (n = 30) or 'high' (n = 25) risk of bias. In the early postoperative period, ERPs improved patient-reported general health (colorectal, HPB, UGI, urological; very low to low certainty), physical health (colorectal, gynecological; very low to low certainty), mental health (colorectal, gynecological; very low certainty), pain (all specialties; very low to moderate certainty), and fatigue (colorectal; low certainty). In the late postoperative period, ERPs improved general health (HPB, UGI, urological; very low certainty), physical health (UGI, gynecological, urological; very low to low certainty), mental health (UGI, gynecological, urological; very low certainty), social health (gynecological; very low certainty), pain (gynecological, urological; very low certainty), and fatigue (gynecological; very low certainty).

CONCLUSION

This review supports that ERPs may have a positive impact on patient-reported postoperative health status (i.e., general, physical, mental, and social health) and symptom experience (i.e., pain and fatigue) after abdominal surgery; however, data were largely derived from low-quality trials. Although these findings contribute important knowledge to inform evidence-based ERP implementation, there remains a great need to improve PRO assessment in studies focused on postoperative recovery.

LI-RADS Morphological Type Predicts Prognosis of Patients with Hepatocellular Carcinoma After Radical Resection

PURPOSE

This study aimed to explore the association of preoperative magnetic resonance imaging (MRI) tumor morphological classification with early recurrence (ER) and overall survival (OS) after radical surgery of hepatocellular carcinoma (HCC).

PATIENTS AND METHODS

A retrospective analysis of 296 patients with HCC who underwent radical resection was performed. On the basis of LI-RADS, tumor imaging morphology was classified into three types. The clinical imaging features, ER, and survival rates of three types were compared. Univariate and multivariate Cox regression analyses were conducted to identify prognostic factors associated with OS and ER after hepatectomy for HCC.

RESULTS

There were 167 tumors of type 1, 95 of type 2, and 34 of type 3. In patients with type 3 HCC, postoperative mortality and ER were significantly higher than in patients with type 1 and type 2 (55.9% versus 32.6% versus 27.5% and 52.9% versus 33.7% versus 28.7%). In multivariate analysis, the LI-RADS morphological type was a stronger risk factor for predicting poor OS [hazard ratio (HR) 2.77, 95% confidence interval (CI) 1.59-4.85, P < 0.001] and ER (HR 2.14, 95% CI 1.24-3.70, P = 0.007). A subgroup analysis revealed that type 3 was associated with poor OS and ER in > 5 cm cases but not in < 5 cm cases.

CONCLUSIONS

ER and OS of patients with HCC undergoing radical surgery can be predicted using the preoperative tumor LI-RADS morphological type, which could help to select personalized treatment plans for patients with HCC in the future.

Efficacy of rigid-angle bronchial blockers for uniportal video-assisted thoracoscopic tumor resection

Background

For uniportal video-assisted thoracoscopic surgery (VATS), which is greatly dependent on satisfactory lung collapse without lung compression from another port, few reports have elucidated the intraoperative efficacy of bronchial blockers (BBs). We hypothesized that operation time would be prolonged if BBs required more intraoperative repositioning during surgical manipulation. We compared the operation times of different surgical procedures performed using BBs with double-lumen tubes (DLTs) in uniportal VATS.

Materials and Methods

Patients who underwent intubated uniportal VATS were enrolled retrospectively from March to May 2019. Data on the patient, anesthetic, and surgical factors were collected. Regression analyses were performed to determine the effect of various factors on operation time.

Results

317 patients who underwent uniportal VATS were included. Wedge resection constituted 70.7%, and anatomic resection constituted 29.3% of procedures. BBs were applied for left- and right-side wedge resection (85.6% and 78.7%, respectively) and left- and right-side anatomic resection (74.1% and 56.4%, respectively). The surgical factors significantly affecting operation time were operation procedures (P < .01), number of lymph nodes sampled (P < .001), and size of tumors (P < .01).

Conclusions

The efficacy of BBs was comparable to that of DLTs for uniportal VATS wedge resection. With significantly less preference for right-side anatomic resection, the efficacy of DLTs was comparable with that of BBs, which were applied in more than half of right-side uniportal anatomic VATS. We conclude that even in uniportal VATSs, rigid-angled BBs demonstrate comparable efficacy with feasible alternatives.

Factors related to preoperative uncertainty among patients with breast cancer in Wenzhou, China: A cross-sectional study

Background

One of the most prevalent psychological signs of breast cancer is uncertainty, which is more prevalent in Chinese patients during the preoperative period. Despite the numerous factors contributing to preoperative uncertainty, there is limited relevant research conducted in China.

Objective

This study aimed to describe the current state of preoperative uncertainty and to investigate the relationship between anxiety, illness perception, social support, and preoperative uncertainty in patients with breast cancer in Wenzhou, China.

Methods

This cross-sectional research used a simple random sampling technique to select 122 participants from a university hospital in Wenzhou, China, from July 2022 to December 2022, employing validated instruments. Descriptive statistics and Pearson's correlation coefficient were utilized to analyze the data.

Results

The average preoperative uncertainty scores of the patients fell within a moderate range (M = 61.92, SD = 7.51). Significant correlations were found between anxiety (r = 0.638, p <0.01), illness perception (r = 0.704, p <0.01), social support (r = -0.481, p <0.01), and preoperative uncertainty.

Conclusions

The results can assist healthcare professionals, especially nurses, in recognizing the factors contributing to uncertainty before surgery in patients with breast cancer. This knowledge enables them to promptly address and minimize this issue, leading to improved outcomes.

Patients with palpitations experience a higher symptom burden prior to breast cancer surgery

PURPOSE

Anxiety, depression, sleep disturbance, fatigue, cognitive dysfunction, and pain are common symptoms reported by patients with breast cancer. Recent evidence suggests that palpitations, a feeling of the heart racing or pounding, may be equally common. Study purpose was to compare the severity and clinically meaningful occurrence rates of common symptoms and quality of life (QOL) outcomes between patients with breast cancer who did and did not report palpitations prior to surgery.

METHODS

Patients (n = 398) were classified as having or not having palpitations using a single item from the Menopausal Symptoms Scale. Valid and reliable measures were used to assess state and trait anxiety, depression, sleep disturbance, fatigue, energy, cognitive function, breast symptoms, and QOL. Between group differences were evaluated using parametric and non-parametric tests.

RESULTS

Patients with palpitations (15.1%) reported significantly higher severity scores for state and trait anxiety, depression, sleep disturbance, and fatigue as well as significant decrements in energy and cognitive function (all p < .05). A higher percentage of these patients had clinically meaningful levels of state anxiety, depression, sleep disturbance and decrements in cognitive function (all p < .05). Except for spiritual well-being, QOL scores were lower in the palpitations group (all p < .001).

CONCLUSION

Findings support the need for routine assessment of palpitations and management of multiple symptoms in women prior to breast cancer surgery.

Expert consensus on the clinical application of totally implantable venous access devices in the upper arm (2022 Edition)

With the widespread adoption of ultrasound guidance, Seldinger puncture techniques, and intracardiac electrical positioning technology for the placement of peripherally inserted central catheters in recent years, an increasing number of medical staff and patients now accept peripheral placement of totally implantable venous access devices (TIVADs) in the upper arm. This approach has the advantage of completely avoiding the risks of hemothorax, pneumothorax, and neck and chest scarring. Medical specialties presently engaged in this study in China include internal medicine, surgery, anesthesiology, and interventional departments. However, command over implantation techniques, treatment of complications, and proper use and maintenance of TIVAD remain uneven among different medical units. Moreover, currently, there are no established quality control standards for implantation techniques or specifications for handling complications. Thus, this expert consensus is proposed to improve the success rate of TIVAD implantation via the upper-arm approach, reduce complication rates, and ensure patient safety. This consensus elaborates on the technical indications and contraindications, procedures and technical points, treatment of complications, and the use and maintenance of upper-arm TIVAD, thus providing a practical reference for medical staff.

Ultrasound assessment of residual gastric volume in older adults undergoing staged-bilateral total knee arthroplasty after consuming carbohydrate-containing fluids: a prospective observational study

BACKGROUND

We compared preoperative residual gastric volume (GV) between the first and second stages of total knee arthroplasty (TKA) in older adults after drinking carbohydrate-containing fluid 2 h prior to surgery.

METHODS

In this study, 36 patients, aged > 65 years, scheduled for staged bilateral TKA with one-week interval, were enrolled. The patients consumed 400 ml of carbohydrate-containing fluid 2 h prior to surgery. Before the induction of spinal anesthesia, the gastric antral cross-sectional area was measured at the first and second TKA using ultrasound, and the residual GV was calculated. The primary outcome was the residual GV. Qualitative GV (grades 0, 1, and 2) and analgesic consumption after the first TKA were assessed as secondary outcomes.

RESULTS

The GV (median [Q1, Q3]) was greater in the second-stage TKA (41.1 [22.5, 62.8] ml) than in the first-stage TKA (10.3 [0.0, 27.1] ml) (P < 0.001). In the qualitative assessment, the distribution was not different between the two stages of TKA (P = 0.219) and only one patient showed grade 2 gastric content in the second TKA. When opioid consumption was converted to an equivalent dose of morphine, an average of 53.9 mg of morphine was required after the first TKA.

CONCLUSIONS

Residual GV after drinking carbohydrate-containing fluid differed according to the stage of TKA, showing a larger residual GV in the second TKA than in the first one. In older adults scheduled to undergo bilateral staged TKA, caution is required in preoperative fasting practice, especially in second-stage surgery.

Receptive music therapy versus group music therapy with breast cancer patients hospitalized for surgery

Hospitalization for breast surgery is a distressing experience for women. This study investigated the impact of music therapy (MT), an integrative approach that is characterized by the establishment of a therapeutic relationship between patients and a certified music therapist, through different musical interventions targeted to the specific needs of the patients. The impact of two different MT experiences was compared on anxiety and distressing emotions.

METHODS

One hundred fifty-one patients during hospitalization for breast surgery were randomly assigned to two music therapy treatment arms: individual/receptive (MTri) vs. group/active-receptive integrated (MTiGrp). Stress, depression, anger, and need for help were measured with the emotion thermometers (ET) and State Trait Anxiety Inventory Y-1 form (STAY-Y1). Data were collected before and after the MT intervention.

RESULTS

Both types of MT interventions were effective in reducing all the variables: stress, depression, anger, and anxiety (T Student p‹0.01). Patients' perception of help received was correlated with a significant reduction in anxiety and distressing emotions during hospitalization for breast surgery.

CONCLUSION

Considerations regarding the implementation of MT interventions in clinical practice are discussed. In individual receptive MT, there was a significant decrease in anxiety levels, whereas in the integrated MT group, there was a higher perception of help received and use of inter-individual resources.

Improvement of inflammatory response and gastrointestinal function in perioperative of cholelithiasis by Modified Xiao-Cheng-Qi decoction

BACKGROUND

In the perioperative period of biliary surgery, various factors can induce the release of a large number of inflammatory factors, leading to an imbalance in pro-inflammatory and anti-inflammatory responses and resulting in gastrointestinal (GI) dysfunction. Enhanced Recovery After Surgery protocols in biliary surgery have been shown to reduce the stress response and accelerate postoperative recovery. It is crucial to reduce the inflammatory response and promote the recovery of GI function after biliary surgery, both of which are the basis and key for perioperative care and postoperative recovery.

AIM

To better understand the effects of Modified Xiao-Cheng-Qi decoction (MXD) on inflammatory response and GI function in the perioperative management of cholelithiasis and their correlation.

METHODS

This was a prospective randomized placebo-controlled trial, in which 162 patients who received biliary tract surgery were randomly assigned to three groups: MXD group, XD group, and placebo-control group. The observed parameters included frequency of bowel sounds, time of first flatus and defecation, time of diet, and amount of activity after surgery. The serum levels of C-reactive protein (CRP), interleukin (IL)-6, IL-10, serum amyloid A protein (SAA), and substance P were measured by the enzyme-linked immunosorbent assay. Then, the spearman correlation coefficient was used to analyze the relationship between the indicators of GI function and inflammation.

RESULTS

Compared to the placebo-control, improvements in GI function were observed in the MXD groups including reduced incidence of nausea, vomiting, and bloating; and earlier first exhaust time, first defecation time, and feeding time after surgery (P < 0.05). On the 1^st and 2^nd d after surgery, IL-6, CRP and SAA levels in MXD group were lower than that in placebo control, but substance P level was higher, compared to the control (P < 0.05). Functional diarrhea occurred in both MXD and XD groups without any other adverse effects, toxic reactions, and allergic reactions. Diarrhea was relieved after the discontinuation of the investigational remedies. Bowel sounds at 12 h after surgery, the occurring time of the first flatus, first defecation, postoperative liquid diet and semi-liquid diet were significantly correlated with levels of IL-6, CRP, SAA and substance P on second day after surgery (P < 0.05).

CONCLUSION

Treatment with MXD can relieve inflammatory response and improve GI function after surgery. Moreover, there are significant correlations between them. Furthermore, it does not cause serious adverse reactions.

Postoperative Discomfort Among Laparotomy Patients from a Selected Hospital at Mangaluru: An Observational Study

Background Factors causing postoperative discomfort after laparotomy are numerous and must be explored in depth. The postoperative distress may significantly affect the patient's state of well-being. Hence, the present study aims to assess the factors contributing to discomfort after laparotomy.

Aim The aim was to assess and compare the discomfort between open and laparoscopic abdominal surgery.

Objectives of the Study

1. To analyze the causes of patient's discomfort after abdominal surgery.

2. To compare the discomfort between open and laparoscopic abdominal surgery.

3. To determine the association between pain and selected variables among open and laparoscopic abdominal surgery.

Materials and Methods An exploratory approach with a prospective observational design was adopted for this study. Using the purposive sampling technique, 100 patients were selected to open and 100 to laparoscopic abdominal surgery groups. Data were collected using demographic and clinical proforma and standardized postoperative discomfort inventory 6 and 24 hours after the surgery. The assessment focused on the study variables such as symptoms after the surgery and the factors contributing to the postoperative discomfort.

Statistical Analysis The collected data were analyzed using descriptive and inferential statistics using the SPSS software version 20.

Results Among 200 participants, most of the open (68%) and laparoscopic abdominal surgeries (42%) belong to 25 to 35 years of age. Also, 54% and 13% were diabetic in open and laparoscopic abdominal surgery groups, respectively. Most samples (56% in open and 68% in laparoscopic surgery) stayed 5 and 10 hours in postoperative ICU. In open and laparoscopic abdominal surgeries, pain is the primary (100%) cause of postoperative discomfort after 6 hours of surgery. Movement restriction is also the reason for significant discomfort both in open (98%) and laparoscopic (100%) abdominal surgeries.

In contrast, pain (99% and 100%), movement restriction (92% and 95%), and abdominal distention (61% and 34%) were the major problems contributing to the patient's discomfort after 24 hours of both open and laparoscopic surgeries too. There was a significant difference in causes of patient discomfort between open and laparoscopic abdominal surgery after 6 hours (P < 0.05), except for discomfort related to IV drip (P = 0.852), constipation (P = 0.2), and chills (P = 0.6).

Conclusion Even though pain is the major distressing factor both in open and laparoscopic surgeries, the current study highlights a few other factors that affect postoperative recovery. Nurses' attention to such distressing factors will fasten patients' recovery and quality of life after abdominal surgery.

Demographic and clinical predictors of post-operative atrial fibrillation in cardio-surgical patients

AIMS

Post-operative atrial fibrillation is defined as an episode of atrial fibrillation that occurs 1-5 days after a surgical procedure in patients without a previous history of atrial fibrillation. Multiple factors such as demographics, cardiac surgical, endogenous, or mental health may relate to post-operative atrial fibrillation.The aim of this study was to identify multivariable high-risk factors for post-operative atrial fibrillation and to propose a risk-assessment tool.

METHODS AND RESULTS

A cross-sectional observational study was conducted in a University Hospital of Greece. Predictor variables examined demographic and clinical variables, anxiety, depression, health-related quality of life, frailty, perioperative mortality (European System for Cardiac Operative Risk Evaluation II), and 10-year survival/mortality risk (Charlson Comorbidity Index score). The outcome variable was post-operative atrial fibrillation. Multivariable analysis was assessed to identify predictors of post-operative atrial fibrillation.Ninety-one patients were included in our sample. Post-operative atrial fibrillation was diagnosed in 44 (48.4%). Factors associated with post-operative atrial fibrillation are the following: age group of 66-75 years [OR 5.78, 95% confidence interval (CI) 1.37-24.34], Charlson Comorbidity Index score (OR 1.42, 95% CI 1.07-1.89), and hours of mechanical ventilation (OR 1.03, 95% CI 1.00-1.06). The Charlson Comorbidity Index score was identified as an independent predictor of post-operative atrial fibrillation (exp: 1.412, 95% CI: 1.017-1.961).

CONCLUSION

Patients with post-operative atrial fibrillation had a higher Charlson Comorbidity Index score. The Charlson Comorbidity Index was identified as an independent clinical predictor of post-operative atrial fibrillation. The risk-assessment tool proposed includes age, Charlson Comorbidity Index score, and hours of mechanical ventilation. Future studies are needed to establish such an assessment.

Differences in Preoperative Health-Related Quality of Life between Women Receiving Mastectomy or Breast Conserving Surgery in a Prospectively Recruited Cohort of Breast Cancer Patients

As rates of total mastectomy rise, the relationships between surgery modality with domains of health-related quality of life is not well understood. This study reports differences in depression, anxiety, pain, and health status among a cohort of women scheduled to receive total mastectomy or breast-conserving surgery. Patient-reported outcomes measured preoperative differences between patients receiving total mastectomy or breast-conserving surgery in a cross-sectional design. Regression analyses was used to model health outcomes and adjust for patient demographics on patient measures. Participants scheduled for total mastectomy were more likely to report more severe symptoms of depression and anxiety. This association was non-significant after adjusting for demographic differences. Younger participants were more likely to be scheduled for total mastectomy. Age was negatively associated with symptoms of depression and anxiety. Screening patients for mental health symptoms may be particularly important among younger patients who were more likely to report depression and anxiety before their surgery and were more likely to receive total mastectomy.

The research frontier of cesarean section recovery: A bibliometric analysis

Background

Cesarean section (CS) has become an effective means to solve dystocia and some obstetric complications, and to save the lives of women and perinatal women. Disparities in quality obstetric care and rehabilitation in CS result from differences in health care systems across regions, and more scientific and reasonable rehabilitation programmes and management measures will benefit more parturient and newborns worldwide who must take CS. In this study, we performed a bibliometric analysis to collect a graphical representation of the CS recovery.

Methods

A total of 995 documents of CS recovery were retrieved from the Web of Science Core Collection (WOSCC) on December 31, 2021, and then VOS viewer 1.6.18 was used for visual analysis.

Results

Over the last 20 years, the researches of CS recovery have gradually increased and it will continue to grow in the next period. Anesthesia and Analgesia is the most popular journal in CS recovery. Most of the representative achievements are concentrated in the relevant institutions of European and American countries, Brendan Carvalho and Ian J. Wrench are among the outstanding scholars in this field, but the overall outcome is limited by limited regional work and lack of broad cooperation and representation. "CS," "surgery," "management," "recovery," "enhanced recovery," and "risk factors" are high frequency keywords, and there is a close relationship between "management" and "enhanced recovery" around the CS and they also become one of the key factors to regulate the condition of patients.

Conclusion

This work firstly analyzed the research condition of CS recovery by a bibliometric analysis. According to the practice guideline, it produces some outstanding representative productions, which involves enhanced recovery after surgery (ERAS) and will continue to be the focus of researchers. More substantive research articles and large-scale clinical studies may greatly enhance the scientific value, and it is necessary to strengthen the ERAS guideline and cooperation between researchers, generate broader consensus and results, and ultimately provide help for CS recovery.

Pathology of catheter-related complications: what we need to know and what should be discovered

Despite the considerable efforts made to increase the prevalence of autogenous fistula in patients on hemodialysis, tunneled cuffed catheters are still an important access modality and used in a high percentage of the hemodialysis population. However, because of the conundrum posed by tunneled cuffed catheters, patients can develop a multitude of complications, including thrombosis, infections, formation of a fibrin sheath, and central vein stenosis, resulting in increased morbidity and mortality as well as placing a heavy burden on the healthcare system. However, with an increasing number of studies now focusing on how to manage these catheter-related complications, there has been less translational research on the pathology of these complications. This review of the most recent literature provides an update on the pathological aspects of catheter-related complications, highlighting what we need to know and what is yet to be discovered. The future research strategies and innovations needed to prevent these complications are also addressed.

The association between double-lumen tube versus bronchial blocker and postoperative pulmonary complications in patients after lung cancer surgery

Background

Both double-lumen tube (DLT) and bronchial blocker (BB) are used for lung isolation in patients undergoing lung cancer surgery. However, the effects of different devices for lung isolation remain inconclusive. Present study was designed to investigate the association between the choice of the two devices and postoperative pulmonary complications (PPCs) in patients with lung cancer.

Methods

In this retrospective cohort study, patients who underwent lung cancer surgery between January 1, 2020 and October 31, 2020 were screened. Patients were divided into two groups according to different devices for lung isolation: DLT group and BB group. Primary outcome was the incidence of a composite of PPCs during postoperative in-hospital stay.

Results

A total of 1721 were enrolled for analysis, of them, 868 received DLT and 853 BB. A composite of PPCs was less common in patients with BB (25.1%, [214/853]) than those received DLT (37.9% [329/868] OR 0.582 95% CI 0.461-0.735 P < 0.001). Respiratory infection was less common in BB group (14.4%, [123/853]) than DLT group (30.3%, [263/868], P<0.001). The incidence of non-PPCs complications was not statistically significant between the 2 groups.

Conclusions

For patients undergoing surgery for lung cancer, the use of BB for lung isolation was associated with a reduced risk of PPCs when compared with DLT.

Personality, Preoperative Anxiety, and Postoperative Outcomes: A Review

Research has shown that personality is associated with anxiety levels in the general population. However, little is known about the relationship between personality and preoperative anxiety and the subsequent health outcomes in patients undergoing surgery. Therefore, this review aimed to identify studies that explored the relationship between personality traits and preoperative anxiety, as well as their association with postoperative outcomes. Existing literature shows that anxiety may play an intermediary role in the relationship between personality and postoperative outcomes. Severe anxiety may partially explain the adverse effects of certain personality traits, such as neuroticism, on postoperative outcomes. However, the relationship between personality traits, preoperative anxiety, and postoperative outcomes remains unclear. Interventions such as clinical evaluation, preoperative counseling, and management strategies can be of great value in identifying and resolving patients' anxiety and negative emotions to improve postoperative outcomes.

The Effects of Aromatherapy on Anxiety and Depression in People With Cancer: A Systematic Review and Meta-Analysis

Background

Anxiety and depression are highly prevalent in people with cancer. Medical therapies are usually prescribed to alleviate anxiety and depression, but they are associated with a variety of adverse effects. Recently, aromatherapy showed potential as a complementary medicine to improve psychological health and wellbeing. However, its effectiveness on relieving anxiety and depression has not been established.

Objective

This study explored the beneficial effects of aromatherapy on psychological symptoms such as anxiety and depression in people with cancer.

Methods

We searched international databases including PubMed, Web of Science, Cochrane Library, Embase, Medline, Ebscohost, ProQuest and Scopus from inception to 31 May 2021. The risk of bias was assessed using the Cochrane Collaboration's tool for assessing risk of bias. The systematic review and meta-analysis were performed according to the PRISMA guidelines. Quantitative analysis was performed on the studies that met our inclusion criteria, and Meta-analysis was performed on the studies with available data by RevMan software.

Results

The quality of the literatures were assessed carefully by two researchers, a total of 17 studies were included in the systematic review and 10 articles were conducted in meta-analysis. The aromatherapy was effective in relieving anxiety (SMD = -0.49, p < 0.05) in people with cancer. Subgroup analysis suggested that most effective methods were aromatic massage (SMD = -0.70, p < 0.005), aromatherapy with lavender essential oils (SMD = -1.12, p < 0.01), short-time interventions (duration < 4weeks) (SMD = -0.87, p < 0.05) and studies in Asia (SMD = -0.83, p < 0.05). Regarding depression and psychological wellbeing, there were no difference between aromatherapy and control groups.

Conclusion

In cancer patients, the aromatherapy was effective for relieving anxiety. However, there was no beneficial effect on depression and psychological wellbeing.

Double-lumen tube versus bronchial blocker in lymphadenectomy along the left recurrent laryngeal nerve for esophageal cancer: a propensity-matched analysis

BACKGROUND

Lymph node (LN) dissection along left recurrent laryngeal nerve (RLN) is challenging in esophagectomy for esophageal cancer, and double-lumen endotracheal tube (DLT) impedes the exposure of this area. The aim of this study was to determine whether bronchial blockers (BB) could be a better choice for this procedure.

METHODS

The clinical characteristics of patients who received McKeown esophagectomy with radical lymph node dissection in Wuhan Tongji Hospital between August 2017 and July 2019 were retrospectively analyzed. The 1:1 propensity score match analysis was performed to compare the short-term effectiveness, the numbers of lymph nodes dissected, and the patterns of recurrence and survival between the two groups.

RESULTS

A total of 294 patients (192 and 102 in the DLT and BB group, respectively) were enrolled in the study. After matching, 204 patients (102 pairs) who underwent one-lung ventilation with DLT or BB displayed no significant variance in baseline characteristics. The BB group had higher number of LNs resected along left RLN (1.8 ± 2.3 vs. 2.5 ± 2.5, P = 0.001). For patients with metastatic left RLN LN, the BB group had longer medium survival time (15 vs. 32 months, P = 0.045), and tended to have longer medium recurrence-free survival time (6 vs. 15 months, P = 0.079), and lower rate of upper mediastinal and cervical LN recurrence (30.00% vs. 66.67%, P = 0.198). The postoperative complications were similar in both groups.

CONCLUSIONS

Compared with DLT, using BB in esophagectomy may allow more radical lymphadenectomy along left RLN.

Data management in diabetes clinical trials: a qualitative study

Background

Clinical trials play an important role in expanding the knowledge of diabetes prevention, diagnosis, and treatment, and data management is one of the main issues in clinical trials. Lack of appropriate planning for data management in clinical trials may negatively influence achieving the desired results. The aim of this study was to explore data management processes in diabetes clinical trials in three research institutes in Iran.

Method

This was a qualitative study conducted in 2019. In this study, data were collected through in-depth semi-structured interviews with 16 researchers in three endocrinology and metabolism research institutes. To analyze data, the method of thematic analysis was used.

Results

The five themes that emerged from data analysis included (1) clinical trial data collection, (2) technologies used in data management, (3) data security and confidentiality management, (4) data quality management, and (5) data management standards. In general, the findings indicated that no clear and standard process was used for data management in diabetes clinical trials, and each research center executed its own methods and processes.

Conclusion

According to the results, the common methods of data management in diabetes clinical trials included a set of paper-based processes. It seems that using information technology can help facilitate data management processes in a variety of clinical trials, including diabetes clinical trials.

Impact of enhanced recovery protocols after pancreatoduodenectomy: meta-analysis

BACKGROUND

This individual-patient data meta-analysis investigated the effects of enhanced recovery after surgery (ERAS) protocols compared with conventional care on postoperative outcomes in patients undergoing pancreatoduodenectomy.

METHODS

The Cochrane Library, MEDLINE, Embase, Scopus, and Web of Science were searched systematically for articles reporting outcomes of ERAS after pancreatoduodenectomy published up to August 2020. Comparative studies were included. Main outcomes were postoperative functional recovery elements, postoperative morbidity, duration of hospital stay, and readmission.

RESULTS

Individual-patient data were obtained from 17 of 31 eligible studies comprising 3108 patients. Time to liquid (mean difference (MD) -3.23 (95 per cent c.i. -4.62 to -1.85) days; P < 0.001) and solid (-3.84 (-5.09 to -2.60) days; P < 0.001) intake, time to passage of first stool (MD -1.38 (-1.82 to -0.94) days; P < 0.001) and time to removal of the nasogastric tube (3.03 (-4.87 to -1.18) days; P = 0.001) were reduced with ERAS. ERAS was associated with lower overall morbidity (risk difference (RD) -0.04, 95 per cent c.i. -0.08 to -0.01; P = 0.015), less delayed gastric emptying (RD -0.11, -0.22 to -0.01; P = 0.039) and a shorter duration of hospital stay (MD -2.33 (-2.98 to -1.69) days; P < 0.001) without a higher readmission rate.

CONCLUSION

ERAS improved postoperative outcome after pancreatoduodenectomy. Implementation should be encouraged.

Citation analysis on the research frontiers and evolution of enhanced recovery after surgery

AIMS

To evaluate the research frontiers and evolution laws in the field of enhanced recovery after surgery (ERAS) and to predict the next direction of development.

BACKGROUND

In recent years, the clinical applications of ERAS have been widely recognized by the medical community. Nursing work is present throughout the entire process, and nurses not only play a role in multidisciplinary coordination, but also maintain independent professional characteristics.

METHODS

The citation analysis method was used to analyze the research documents in the Web of Science database over the last 10 years.

RESULTS

The number of documents in the field published from 2011 to 2020 increased annually. The application in colorectal surgery was the most important research frontier. From 2016 to 2020, the research frontiers were diversified. The application in colorectal surgery remains the most important research frontier, and perioperative nursing will play an important role in the future.

CONCLUSIONS

This study used citation analysis to analyze the research frontiers and evolution of ERAS in the last 10 years.

IMPLICATIONS FOR NURSING MANAGEMENT

This research will help nursing managers to carry out research and clinical promotion plans in the ERAS field and guide the transformation of scientific research achievements into nursing practice.

Preoperative checklist to reduce the risk of cardiac implantable electronic device infections

Cardiac implantable electronic device (CIED) infection represents a dramatic event with a high mortality rate (>3x) despite antibiotic therapy and device extraction; therefore, the real winning strategy in this situation could be represented by prevention. Antibiotic prophylaxis and antibiotic-releasing envelope are effective in improving patient outcome; however, healthcare costs related to CIED infections remain high over the years. In this review we would keep the attention on a pre-surgical checklist to reduce the risk of CIED infections. In fact, checklist is an effective instrument for medical care quality improvement mainly used in surgery, but not very commonly in cath-lab and electrophysiology procedures. All steps of this checklist are of proven effectiveness in reducing the risk of CIED infections but, up till now, they are not considered together in a pre-surgical approach.

Hypotension during propofol sedation for colonoscopy: an exploratory analysis

BACKGROUND

Intraoperative and postoperative hypotension occur commonly and are associated with organ injury and poor outcomes. Changes in arterial blood pressure (BP) during procedural sedation are not well described.

METHODS

Individual patient data from five trials of propofol sedation for colonoscopy and a clinical database were pooled and explored with logistic and linear regression. A literature search and focused meta-analysis compared the incidence of hypotension with propofol and alternative forms of procedural sedation. Hypotensive episodes were characterised by the original authors' definitions (typically systolic BP <90 mm Hg).

RESULTS

In pooled individual patient data (n=939), 36% of procedures were associated with episodes of hypotension. Longer periods of propofol sedation and larger propofol doses were associated with longer-lasting and more-profound hypotension. Amongst 380 patients for whom individual BP measurements were available, 107 (28%) experienced systolic BP <90 mm Hg for >5 min, and in 89 (23%) the episodes exceeded 10 min. Meta-analysis of 18 RCTs identified an increased risk ratio for the development of hypotension in procedures where propofol was used compared with the use of etomidate (two studies; n=260; risk ratio [RR] 2.0 [95% confidence interval: 1.37-2.92]; P=0.0003), remimazolam (one study; n=384; RR 2.15 [1.61-2.87]; P=0.0001), midazolam (14 studies; n=2218; RR 1.46 [1.18-1.79]; P=0.0004), or all benzodiazepines (15 studies; n=2602; 1.67 [1.41-1.98]; P<0.00001). Hypotension was less likely with propofol than with dexmedetomidine (one study; n=60; RR 0.24 [0.09-0.62]; P=0.003).

CONCLUSIONS

Hypotension is common during propofol sedation for colonoscopy and of a magnitude and duration associated with harm in surgical patients.

Effect of balanced anaesthesia with and without modified pectoralis nerve block on postoperative analgesia after breast surgeries: A randomised controlled trial

Background and Aims:

Modified pectoral nerve block (PEC) has been reported to have variable effects on perioperative pain in patients undergoing surgery for carcinoma breast. This randomised controlled trial was conducted to study the effect of modified PEC on postoperative pain relief in patients undergoing breast surgery.

Methods:

Fifty patients with carcinoma breast undergoing breast surgery were randomised to receive a modified PEC block consisting of 30 ml of ropivacaine 0.2% after induction of anaesthesia (PEC group) or no block (GA group) in this prospective randomised trial. Time to first rescue analgesia was recorded as primary outcome. Other secondary outcomes recorded were postoperative visual analogue scale (VAS) scores, number of rescue boluses and 24-h fentanyl consumption.

Results:

There was no significant difference in time to first rescue analgesia between the two groups, with mean difference (95% confidence interval) of 22.91 (−6.8 to 52.69) min. Amount of fentanyl required to keep pain VAS less than 3 was also comparable between the two groups, mean (standard deviation) of 42.0 μg (17.42) in GA group versus 43.24 μg (17.22) in PEC group; P = 0.830.20/25 patients required rescue analgesia in GA group as compared to 17/25 in PEC group (P = 0.334). The postoperative VAS scores were also comparable between the groups at all time intervals.

Conclusion:

Balanced anaesthesia supplemented with modified PEC block performed after general anaesthesia did not improve the postoperative pain in patients undergoing modified radical mastectomy.

Stress and autonomic nerve dysfunction monitoring in perioperative gastric cancer patients using a smart device

Background

Heart rate variability (HRV), a sensitive marker of stress and autonomic nervous disorders, was significantly decreased in cardiovascular disease, inflammation, and surgical injury. However, the effect of radical gastrectomy on HRV parameters needs to be further investigated.

Methods

A prospective, observational study including 45 consecutive enrolled patients undergoing radical gastrectomy in our enhanced recovery after surgery (ERAS) programs was conducted. Frequency‐ and time‐domain parameters of HRV from 1 day prior to operation to 4 days postoperatively were continuously measured. Meanwhile, plasma cortisol and inflammatory markers were recorded and correlated to HRV parameters.

Results

Heart rate variability showed a solidly circadian rhythm. Anesthesia severely disturbed HRV parameters, resulting in a reduction of most of the HRV parameters. Frequency‐domain parameter (including VLF) and time‐domain parameters (including the SDNN, SDANN, and triangular index) of HRV demonstrated a significant reduction compared to preoperative values on the postoperative day 1 (Pod1), and these HRV parameters could return to baseline on Pod2 or Pod3, indicating surgical stress and autonomic nerve dysfunction existed in the early postoperative period. Inflammatory biomarkers were significantly elevated on Pod1 and Pod3. Plasma cortisol decreased significantly on Pod1 and Pod3. Both inflammatory biomarkers and plasma cortisol had no significant correlation with HRV parameters.

Conclusions

Compared with plasma cortisol and inflammation biomarkers, HRV is more sensitive to detect surgical stress and autonomic nervous dysfunction induced by radical gastrectomy in patients with gastric cancer.
