Randomized clinical trial of psychological support and sleep adjuvant measures for postoperative sleep disturbance in patients undergoing oesophagectomy

Effect of perioperative intravenous ketamine on postoperative sleep disturbance in patients undergoing non-cardiac surgery: A systematic review and meta-analysis

Background and Aims

Postoperative sleep disturbance (PSD) is a common condition that may lead to pain, cognitive impairment, depression, and delayed recovery. This review evaluates the efficacy of perioperative intravenous ketamine in alleviating PSD and offers evidence-based recommendations for clinical practice.

Methods

A systematic search was performed in PubMed, Embase, Cochrane Library, Wanfang Data, VIP Information Resource System, China National Knowledge Infrastructure and China Biology Medicine disc (SinoMed) up to 6th November 2024. This article included a meta-analysis of randomised controlled trials (RCTs) along with a Grading of Recommendations Assessment, Development and Evaluation analysis.

Results

A total of 2355 patients from 21 RCTs were analysed. The pooled results indicated that ketamine improved sleep quality compared to placebo on the first postoperative day, as evidenced by a reduction in Pittsburgh Sleep Quality Index scores [mean difference (MD): -2.69; 95% confidence interval (CI): -3.95, -1.42; P < 0.0001, I 2 = 96%]. Ketamine also improved sleep quality on the second postoperative day (MD: -2.45; 95% CI: -3.99, -0.91; P = 0.002, I 2 = 96%) and during the first three postoperative days (MD: -2.90; 95% CI: -4.79, -1.00; P = 0.003, I 2 = 97%). In addition, ketamine reduced Visual Analogue Scale scores for pain (MD: -0.38; 95% CI: -0.55, -0.21; P < 0.00001, I 2 = 84%). These results suggest that ketamine reduces PSDs and pain without significantly increasing adverse reactions. However, given the high heterogeneity and limited quality of evidence in this review, the results should be interpreted with caution.

Conclusion

This meta-analysis indicates that administering ketamine during the perioperative period can enhance postoperative sleep quality. However, the optimal dose, timing and method of administration remain undetermined, emphasising the need for further research to establish standardised guidelines.

Prevalence, Risk Factors, and Intervention of Long-Term Sleep Disturbance After Intensive Care Unit Discharge: A Scoping Review

Sleep disturbance in the intensive care unit (ICU) is common and often persistent after discharge. Sleep disturbance after ICU discharge, often classified under post-intensive care syndrome (PICS), affects health-related quality of life (HRQOL). The aim of the current review was to map long-term sleep disturbance after ICU discharge, explore related factors, and suggest prevention and treatment measures, including those related to PICS. We searched the PubMed, CINAHL, and CENTRAL databases until June 12, 2024, using keywords related to ICU, sleep disturbance, and recovery. Inclusion criteria were the inclusion of adult patients, analysis of sleep disturbance after ICU, and evaluation of risk factors or interventions. Reviews, case reports, and non-original studies were excluded. A total of 1,786 studies on sleep disturbance after ICU discharge were initially identified, with 52 studies ultimately included after screening. Prevalence of sleep disturbance after ICU discharge was calculated from 42 studies, with rates of 55.0% at less than one month, 49.6% at 1-3 months, 39.2% at 4-6 months, 23.2% at 7-12 months, and 15.0% over one year. Risk factors for sleep disturbance included older age, female sex, pre-hospital sleep disturbance, ICU and hospital lengths of stay, duration of mechanical ventilation, duration of sedation or analgesia, pain, delirium, and poor sleep quality during hospital ward. Long-term sleep disturbance was associated with PICS. Sleep disturbance was associated with physical disability, cognitive impairment, mental dysfunction (especially depression, post-traumatic stress disorder, and anxiety), and HRQOL, assessed at 4-6 months after hospitalization. Two randomized controlled trials (RCTs) examined interventions for sleep disturbance. Psychological counseling and a 12-month nurse-led collaborative care intervention were found effective in improving long-term sleep disturbance. On the other hand, the use of sleep aids such as earplugs and eye masks in the ICU had no such effect. Sleep disturbance after ICU discharge is common, with over half of the patients being affected within one month, and a link to PICS symptoms exists, highlighting the need for further research on comprehensive interventions.

Association Between Preoperative Sleep Disturbance and Postoperative Delirium in Elderly: A Retrospective Cohort Study

Purpose

Postoperative sleep disturbance, characterized by diminished postoperative sleep quality, is a risk factor for postoperative delirium (POD); however, the association between pre-existing sleep disturbance and POD remains unclear. This study aimed to evaluate the association between preoperative sleep disturbance and POD in elderly patients after non-cardiac surgery.

Patients and methods

This retrospective cohort study was conducted at a single center and enrolled 489 elderly patients who underwent surgery between May 1, 2020, and March 31, 2021. Patients were divided into the sleep disorder (SD) and non-sleep disorder (NSD) groups according to the occurrence of one or more symptoms of insomnia within one month or sleep- Numerical Rating Scale (NRS)≥6 before surgery. The primary outcome was the incidence of POD. Propensity score matching analysis was performed between the two groups. Multiple logistic regression analysis was performed to identify the risk factors for POD.

Results

In both the unmatched cohort (16.0% vs 6.7%, P=0.003) and the matched cohort (17.0% vs 6.2%, P=0.023), the incidence of POD was higher in the SD group than in the NSD group. In addition, the postoperative sleep quality and the VAS score at postoperative 24 h were significantly lower in the SD group than in the NSD group. Multivariate logistic regression analysis indicated that age (Odds Ratio, 1.13 [95% CI: 1.04-1.23], P=0.003) and preoperative sleep disturbance (Odds Ratio, 3.03 [95% CI: 1.09-9.52], P=0.034) were independent risk factors for the development of POD.

Conclusion

The incidence of POD was higher in patients with pre-existing sleep disturbance than those without it. Whether improving sleep quality for preoperative sleep disturbance may help prevent POD remains to be determined.

Effect of transcranial direct current stimulation on postoperative sleep disturbance in older patients undergoing lower limb major arthroplasty: a prospective, double-blind, pilot, randomised controlled trial

Background

Postoperative sleep disturbance (PSD) is a common and serious postoperative complication and is associated with poor postoperative outcomes.

Aims

This study aimed to investigate the effect of transcranial direct current stimulation (tDCS) on PSD in older patients undergoing lower limb major arthroplasty.

Methods

In this prospective, double-blind, pilot, randomised, sham-controlled trial, patients 65 years and over undergoing lower limb major arthroplasty were randomly assigned to receive active tDCS (a-tDCS) or sham tDCS (s-tDCS). The primary outcomes were the objective sleep measures on postoperative nights (N) 1 and N2.

Results

116 inpatients were assessed for eligibility, and a total of 92 patients were enrolled; 47 received a-tDCS and 45 received s-tDCS. tDCS improved PSD by altering the following sleep measures in the a-tDCS and s-tDCS groups; the respective comparisons were as follows: the promotion of rapid eye movement (REM) sleep time on N1 (64.5 (33.5-105.5) vs 19.0 (0.0, 45.0) min, F=20.10, p<0.001) and N2 (75.0 (36.0-120.8) vs 30.0 (1.3-59.3) min, F=12.55, p<0.001); the total sleep time on N1 (506.0 (408.0-561.0) vs 392.0 (243.0-483.5) min, F=14.13, p<0.001) and N2 (488.5 (455.5-548.5) vs 346.0 (286.5-517.5) min, F=7.36, p=0.007); the deep sleep time on N1 (130.0 (103.3-177.0) vs 42.5 (9.8-100.8) min, F=24.4, p<0.001) and N2 (103.5 (46.0-154.8) vs 57.5 (23.3-106.5) min, F=8.4, p=0.004); and the percentages of light sleep and REM sleep on N1 and N2 (p<0.05 for each). The postoperative depression and anxiety scores did not differ significantly between the two groups. No significant adverse events were reported.

Conclusion

In older patients undergoing lower limb major arthroplasty, a single session of anodal tDCS over the left dorsolateral prefrontal cortex showed a potentially prophylactic effect in improving postoperative short-term objective sleep measures. However, this benefit was temporary and was not maintained over time.

Non-pharmacological interventions to improve sleep quality and quantity for hospitalized adult patients-co-produced study with surgical patient partners: systematic review

BACKGROUND

Hospitalized patients experience sleep disruption with consequential physiological and psychological effects. Surgical patients are particularly at risk due to surgical stress and postoperative pain. This systematic review aimed to identify non-pharmacological interventions for improving sleep and exploring their effects on sleep-related and clinical outcomes.

METHODS

A systematic literature search was performed in accordance with PRISMA guidelines and was preregistered on the Open Science Framework (doi: 10.17605/OSF.IO/EA6BN) and last updated in November 2023. Studies that evaluated non-pharmacological interventions for hospitalized, adult patients were included. Thematic content analysis was performed to identify hypothesized mechanisms of action and modes of administration, in collaboration with a patient partner. Risk of bias assessment was performed using the Cochrane Risk Of Bias (ROB) or Risk Of Bias In Non-Randomized Studies - of Interventions (ROBINS-I) tools.

RESULTS

A total of 59 eligible studies and data from 14 035 patients were included; 28 (47.5%) were randomized trials and 26 included surgical patients (10 trials). Thirteen unique non-pharmacological interventions were identified, 17 sleep measures and 7 linked health-related outcomes. Thematic analysis revealed two major themes for improving sleep in hospital inpatients: enhancing the sleep environment and utilizing relaxation and mindfulness techniques. Two methods of administration, self-administered and carer-administered, were identified. Environmental interventions, such as physical aids, and relaxation interventions, including aromatherapy, showed benefits to sleep measures. There was a lack of standardized sleep measurement and an overall moderate to high risk of bias across all studies.

CONCLUSIONS

This systematic review has identified several sleep interventions that are likely to benefit adult surgical patients, but there remains a lack of high-quality evidence to support their routine implementation.

The brief measure of preoperative emotional stress screens preoperative maladaptive psychological features and predicts postoperative opioid use: an observational study

BACKGROUND

The Brief Measure of Preoperative Emotional Stress (B-MEPS) is a suitable screening tool for Preoperative Emotional Stress (PES). However, personalized decision-making demands practical interpretation of the refined version of B-MEPS. Thus, we propose and validate cut-off points on the B-MEPS to classify PES. Also, we assessed if the cut-off points screened preoperative maladaptive psychological features and predicted postoperative opioid use.

METHODS

This observational study comprises samples of two other primary studies, with 1009 and 233 individuals, respectively. The latent class analysis derived emotional stress subgroups using B-MEPS items. We compared membership with the B-MEPS score through the Youden index. Concurrent criterion validity of the cut-off points was performed with the severity of preoperative depressive symptoms, pain catastrophizing, central sensitization, and sleep quality. Predictive criterion validity was performed with opioid use after surgery.

RESULTS

We chose a model with three classes labeled mild, moderate, and severe. The Youden index points -0.1663 and 0.7614 of the B-MEPS score classify individuals, in the severe class, with a sensitivity of 85.7% (80.1%-90.3%) and specificity of 93.5% (91.5-95.1%). The cut-off points of the B-MEPS score have satisfactory concurrent and predictive criterion validity.

CONCLUSIONS

These findings showed that the preoperative emotional stress index on the B-MEPS offers suitable sensitivity and specificity for discriminating the severity of preoperative psychological stress. They provide a simple tool to identify patients prone to severe PES related to maladaptive psychological features, which might influence the perception of pain and analgesic opioid use in the postoperative period.

The effectiveness of non-pharmacological sleep interventions for improving inpatient sleep in hospital: A systematic review and meta-analysis

BACKGROUND

Sleep disturbance is common in hospital. The hospital environment can have a negative impact on sleep quality, through factors such as noise, light, temperature, and nursing care disruptions. Poor sleep can lead to delays in recovery, wound healing, and increase risk of post-operative infection.

METHODS

We conducted a systematic review evaluating the effectiveness of non-pharmacological sleep interventions for improving inpatient sleep. The primary outcome was sleep quality, the secondary outcome was length of hospital stay, the harm outcome was adverse events. MEDLINE, Embase, CINAHL, PsycINFO and the Cochrane Library were searched from inception to 17^th February 2022. Meta-analysis was conducted using a fixed effects model, with narrative synthesis for studies with no useable data. Risk of bias was assessed with the Cochrane tool.

RESULTS

76 studies identified with 5375 people randomised comparing 85 interventions. Interventions focused on physical sleep aids (n = 26), relaxation (n = 25), manual therapy (n = 12), music (n = 9), psychological therapy (n = 5), light therapy (n = 3), sleep protocols (n = 2), milk and honey (n = 1), exercise (n = 1), and nursing care (n = 1). In meta-analysis, medium to large improvements in sleep quality were noted for sleep aids, relaxation, music, and manual therapies. Results were generally consistent in studies at lower risk of bias. Length of hospital stay and adverse events were reported for some studies, with benefit in some trials but this was not consistent across all interventions.

CONCLUSIONS

Physical sleep aids, relaxation, manual therapy and music interventions have a strong evidence base for improving inpatient sleep quality. Research is needed to evaluate how to optimise interventions into routine care.

The Health of Healthcare Professionals in Italian Oncology: An Analysis of Narrations through the M.A.D.I.T. Methodology

From the analysis of the scientific literature relating to the health of oncological patients, the need to consider the global dimension of health of individuals emerges, which subsumes the bodily dimension and involves all the actors who offer their contribution to it in different ways. In this direction, the state of the art of the health construct offered by healthcare professionals highlights a lack of scientific contributions to the specific subject although these professionals are fundamental figures in oncological diagnosis setups. Considering, therefore, the healthcare roles as an integral part of the interactive framework where the oncological patient is placed, this paper offers the results of an Italian study relating to the health of healthcare professionals who take charge of patients with a neoplasia diagnosis. In particular, through an analysis of the discursive productions of 61 participants (healthcare workers, oncological patients and citizens) by the M.A.D.I.T. methodology (Methodology for the Analysis of Computerized Textual Data), this study aimed at observing the discursive reality of health offered by healthcare workers. The collected data highlight a low degree of health expressed by the healthcare professionals, who are strongly typified by rhetoric such as “the one who is destined to suffer psychologically”. These narrations limit the possibilities of development of different narrations in depicting these professionals: critical repercussions in the interaction with the oncological patients emerged, as well as in their global health degree. In conclusion, the results show the need for deep investigation into the impact that the health degree of health professionals can have on the patients they take charge of.

Managing the Consequences of Oncological Major Surgery: A Short- and Medium-Term Skills Assessment Proposal for Patient and Caregiver through M.A.D.I.T. Methodology

The effects of cancer surgery and treatment harm patients’ life and working ability: major causes of this can be intensified by the postoperative symptoms. This study, the first part of the HEAGIS project (Health and Employment after Gastrointestinal Surgery), proposes a method to assess patients and caregivers’ competences in dealing with postoperative course and the related needs to improve the adequate competences. In this observational study, an ad hoc structured interview was conducted with 47 patients and 15 caregivers between the third and fifteenth postoperative day. Oesophageal (38%), esophagogastric junction (13%), gastric (30%), colon (8%) and rectum (11%) cancer patients were considered. Computerized textual data analysis methodology was used to identify levels of competences. Text analysis highlighted three different levels (low, medium and high) of four specific types of patients and caregivers’ competences. In particular, the overall trend of the preview of future scenarios and use of resource competences was low. Less critical were situation evaluation and preview repercussion of own actions’ competences. Caregivers’ trends were similar. The Kruskal–Wallis test did not distinguish any differences in the level of competences related to the characteristics of the participants. Patients and caregivers are not accurate in planning the future after surgery, using personal beliefs rather than referring to physicians, and not recognizing adequate resources. The medium-low competences’ trend leads to unexpected critical situations, and patients could not deal with them in a maximally effective way. Both patients and caregivers should be taken over by healthcare professionals to improve patients’ competences and make the curative surgery effective in daily life.

Totally Implantable Venous Access Devices: A Randomized Controlled Trial on the Effect of Psychological Support on Quality of Life and Body Image (BI-PORT)

Background: The presence of totally implantable venous access devices (TIVADs), as any permanent or semipermanent medical devices, has an impact on the quality of life (QoL) of patients. Therefore, the purpose of this trial was to evaluate the efficacy of psychological support for patients undergoing this procedure.

Methods: This randomized controlled trial (RCT) aimed to compare the efficacy of a psychological intervention vs. standard care on QoL in patients receiving TIVAD for chemotherapy treatment (ClinicalTrials.gov NCT02075580). The trial was conducted at the Veneto Institute of Oncology IOV-IRCCS (Padua, Italy) between October 2013 and September 2018. Participants were neoplastic adults receiving TIVAD for chemotherapy treatment for any cancer, not undergoing visible demolitive interventions, without psychopathological diagnosis and language understanding. The exclusion criteria were patients without a diagnosis of cancer, with psychopathological diagnosis, or with language misunderstanding.

Results: The variation of C30-QL2 and BR32-BI was not statistically different between intervention and control arms in men and women. However, the variation of C30-SF was statistically better in the intervention than control arm in men [mean difference (MD) 22.3, 95% CI 3.5 to 41.0] but not in women (MD −2.7, 95% CI −24.0 to 18.7). The variations of the other secondary outcome measures were not statistically different between intervention and control arms.

Conclusion: Psychological support did not show any clear advantages on global QoL and body image perception in patients at 15 days after TIVAD insertion for chemotherapy. In contrast, male patients might benefit from even a very short psychological counseling before or during chemotherapy even if they do not seem to ask for it.

The Role of Perioperative Sleep Disturbance in Postoperative Neurocognitive Disorders

Postoperative neurocognitive disorder (PND) increases the length of hospital stay, mortality, and risk of long-term cognitive impairment. Perioperative sleep disturbance is prevalent and commonly ignored and may increase the risk of PND. However, the role of perioperative sleep disturbances in PND remains unclear. Nocturnal sleep plays an indispensable role in learning, memory, and maintenance of cerebral microenvironmental homeostasis. Hospitalized sleep disturbances also increase the incidence of postoperative delirium and cognitive dysfunction. This review summarizes the role of perioperative sleep disturbances in PND and elucidates the potential mechanisms underlying sleep-deprivation-mediated PND. Activated neuroinflammation and oxidative stress; impaired function of the blood-brain barrier and glymphatic pathway; decreased hippocampal brain-derived neurotrophic factor, adult neurogenesis, and sirtuin1 expression; and accumulated amyloid-beta proteins are associated with PND in individuals with perioperative sleep disorders. These findings suggest that the improvement of perioperative sleep might reduce the incidence of postoperative delirium and postoperative cognitive dysfunction. Future studies should further investigate the role of perioperative sleep disturbance in PND.

Sleep Disturbances After General Anesthesia: Current Perspectives

The purpose of this article is to review (1) sleep mechanism under general anesthesia, harmful effects of postoperative sleep disturbances; (2) risk factors associated with postoperative sleep disturbances; (3) measures to prevent and improve postoperative sleep disturbances. General anesthesia changes the postoperative sleep structure especially in elderly patients after major surgery and results in a high incidence rate of sleep disturbances. Sleep disturbances produce harmful effects on postoperative patients and lead to a higher risk of delirium, more cardiovascular events, and poorer recovery. Some researchers do propose non-pharmacological treatments such as attention to environmental and psychological factors, application of electroacupuncture (EA) technology and pharmacological treatments are helpful, but larger high-quality clinical trials with longer following-up are needed to further investigate the efficacy and safety.

QOLEC2: a randomized controlled trial on nutritional and respiratory counseling after esophagectomy for cancer

Background

Esophagectomy for cancer strongly impairs quality of life. The aim of this trial was to evaluate the effect of the nutritional and respiratory counseling on postoperative quality of life.

Methods

At hospital discharge, patients were randomized into four groups receiving respectively: nutritional and respiratory counseling, nutritional counseling alone, respiratory counseling alone, or standard care. The main endpoint was the impairment in quality of life in the first month after surgery. Linear mixed effect models were estimated to assess mean score differences (MDs) in quality of life scores.

Results

Patients receiving nutritional counseling reported less appetite loss (MD − 17.7, 95% CI − 32.2 to −3.3) than those not receiving nutritional counseling at 1 month after surgery. Dyspnea was similar between patients receiving vs. those not receiving respiratory counseling (MD − 3.1, 95% CI − 10.8 to 4.6). Global quality of life was clinically similar between patients receiving vs. those not receiving nutritional counseling over time (MD 0.9, 95% CI − 5.5 to 7.3), as well as in patients receiving vs. those not receiving respiratory counseling over time (MD 0.7, 95% CI − 5.9 to 7.2).

Conclusions

Intensive postoperative care does not affect global quality of life even if nutritional counseling reduced appetite loss.

Comparison of Morning and Evening Operation Under General Anesthesia on Intraoperative Anesthetic Requirement, Postoperative Sleep Quality, and Pain: A Randomized Controlled Trial

OBJECTIVE

Postoperative sleep disorders can cause serious adverse effects on postoperative outcomes. The purpose of our study was to compare the effects of the timing of surgery under general anesthesia on intraoperative anesthetic drug requirements, postoperative sleep quality and pain in patients.

MATERIALS AND METHODS

Eighty-four patients who underwent selective laparoscopic abdominal surgeries under general anesthesia were randomly assigned to the Day Group (8:00-12:00) or the Night Group (18:00-22:00). The portable sleep monitor (PSM) was used to determine sleep quality on the night before surgery (Sleep-preop), the first night after surgery (Sleep POD 1), and the third night after surgery (Sleep POD 3). The visual analog scale (VAS) was used to evaluate postoperative pain scores and the Athens Insomnia Scale (AIS) was used for assessing insomnia symptoms. The total dose of general anesthetics required and adverse effects after surgery were also assessed.

RESULTS

Compared to Sleep-preop, patients presented with a lower sleep efficiency and a higher AIS score during Sleep POD 1 and Sleep POD 3. Furthermore, the Night Group had a significantly lower proportion of rapid eye movement sleep, stable sleep, and unstable sleep than did the Day Group at Sleep POD 1 and Sleep POD 3. The dosage of propofol and remifentanil required in the Day Group was significantly higher than that in the Night Group. Furthermore, patients in the Day Group had better pain relief, with a lower VAS score at 1, 6, 12, and 24 hours after surgery. The incidences of postoperative nausea and vomiting and dizziness were significantly higher in the Night Group than those in the Day Group.

CONCLUSION

Morning operations required a higher dose of anesthetic drugs than did evening operations, which may be related to the circadian rhythm. The degree of postoperative sleep disorders was greater when the operation was performed in the evening than in the morning, which was also associated with increased pain perception and increased incidence of postoperative adverse effects. Thus, our results suggest that patients with hyperalgesia and sleep disorders may benefit from operations performed in the morning.

Psychological support for patients with cancer: evidence review and suggestions for future directions

PURPOSE OF REVIEW

Psychological distress and mental health comorbidity are common in cancer. Various therapeutic frameworks have been used for interventions to improve psychological wellbeing and quality of life in cancer patients with mixed results. This article reviews contributions to that literature published since January 2017.

RECENT FINDINGS

The majority of new psychological intervention research in cancer has used cognitive behavioural therapy (CBT) or mindfulness-based interventions. CBT has been considered a gold-standard intervention and recent evidence justifies continuation of this. Recent reviews call into question the validity of evidence for mindfulness-based interventions. A smaller number of trials using acceptance and commitment therapy, meta-cognitive therapy, dignity therapy and coaching have emerged, and whereas findings are promising, additional fully powered trials are required. Weaker evidence exists for counselling, support-based and narrative therapy interventions.

SUMMARY

Efficacious, timely and acceptable psychological interventions are a necessary component of comprehensive cancer care. There is some way to go before the evidence conclusively points towards which interventions work for which cancer groups and for which specific outcomes. Methodological limitations must be addressed in future trials; at the forefront remains the need for fully powered, head-to-head comparison trials.

Psychological support of esophageal cancer patient?

Important questions are still open about psychological aspects in esophageal cancer (EC) and about the related psychological support. How to cope with the cancer diagnosis and poor prognosis: a psychological counselling may be a valid option to personalize the communication to patients with a poor prognosis. How to cope with long chemoradiotherapy: after neoadjuvant therapy, patients know that curative process is not completed, and they perceive the severity of the neoadjuvant side effects, considering themselves "fragile" and far from a healthy condition before the major surgery they are going to undergo. Therefore, this is a particularly crucial point when psychological support may be useful. How to cope with change of nutritional habits: esophagectomy for cancer strongly impairs nutritional function in the early postoperative period and feeding Jejunostomy impairs emotional function. How to cope with sleep disturbances: most cancer patients report disturbed sleep after cancer diagnosis and/or following cancer treatment. Psychological intervention aims to identify underlying concerns worsening sleep quality. How to cope with postoperative complications: the occurrence of such complications reduces patient's satisfaction and has a negative effect on doctor-patient relationship. How to cope with long-term functions impairment: EC patients need a plan for the future.

Postoperative sleep disorders and their potential impacts on surgical outcomes

Postoperative sleep disturbance is a common occurrence with significant adverse effects on patients including delayed recovery, impairment of cognitive function, pain sensitivity and cardiovascular events. The development of postoperative sleep disturbance is multifactorial and involves the surgical inflammatory response, the severity of surgical trauma, pain, anxiety, the use of anesthetics and environmental factors such as nocturnal noise and light levels. Many of these factors can be managed perioperatively to minimize the deleterious impact on sleep. Pharmacological and non-pharmacological treatment strategies for postoperative sleep disturbance include dexmedetomidine, zolpidem, melatonin, enhanced recovery after surgery (ERAS) protocol and controlling of environmental noise and light levels. It is likely that a combination of pharmacological and non-pharmacological therapies will have the greatest impact; however, further research is required before their use can be routinely recommended.

Long-term quality of life after esophagectomy with gastric pull-up

BACKGROUND AND OBJECTIVES

Data on long-term health-related quality of life (HRQL) after esophagectomy for cancer show contradictory results. The aim was to analyze long-term HRQL at 3 or more years after esophagectomy.

METHODS

Survivors were identified among patients who had undergone esophagectomy during 2007-2013 using the local clinic database. Quality of life was assessed using the European Organization for Research and Treatment of Cancer QLQ-C30 and OG25 questionnaires. Specific aspects were selected a priori and compared with published scores from European healthy subjects (mean difference, MD).

RESULTS

Sixty-five long-term survivors (median follow-up 4 years) were identified. All functional scales and most symptom scales were clinically similar between EC long-term survivors and European healthy subjects. Survivors reported more problems concerning eating (MD 13.1, 95% C.I. 10.6-15.6) and reflux (MD 19.7, 95% C.I. 15.9-23.5). HQRL variation from discharge to long term was available in 27 participants who reported improvements in role functioning (MD 40.1, 95%C.I. 24.3-56.0) and dysphagia (MD -41.9, 95% C.I. -51.7 to 32.0).

CONCLUSIONS

Long-term HRQL after esophagectomy is similar between EC survivors and European healthy subjects, despite persisting reflux and eating problems. Further research may focus on improvements of postoperative alimentary habits.

Immunonutrition before esophagectomy: Impact on immune surveillance mechanisms

Preoperative oral immunonutrition was demonstrated to improve immune response and to decrease the infection rate in patients with cancer. This study aimed to assess how immunonutrition could influence the immune cell response in the mucosal microenvironment of esophageal adenocarcinoma. Therefore, A prospective cohort of consecutive patients undergoing esophagectomy for esophageal adenocarcinoma was enrolled. A subgroup of them was given preoperative oral immunonutrition with Oral Impact® and was compared to those who received no preoperative supplementation. Mucosal samples from healthy esophagus were obtained at esophagectomy. Histology, immunohistochemistry, gene expression analysis, and cytofluorimetry were performed. Markers of activation of antigen-presenting cells (CD80, CD86, and HLA-I), innate immunity (TLR4 and MyD88), and cytotoxic lymphocyte infiltration and activation (CD8, CD38, CD69, and CD107) were measured. In all, 50 patients received preoperative Oral Impact® and 129 patients received no nutritional support. CD80, CD86, MyD88, and CD69 messenger RNA expression was significantly increased in patients receiving immunonutrition compared to controls. In the subgroup of patients with stages I-II cancer, the rate of epithelial cells expressing CD80 and HLA-ABC was significantly higher in those receiving immunonutrition compared to controls as well as CD8+ CD28+ cell rate. Immunonutrition administration before surgery was significantly associated to increased degranulating CD8 and natural killer cells (CD107+) infiltrating the healthy esophageal mucosa. All the comparisons were adjusted for cancer stage and preoperative therapy. In conclusion, in healthy esophageal mucosa of patients undergoing esophagectomy, a 5-day course of immunonutrition enhances expression of antigen-presenting cells activity and increased CD8+ T cell activation and degranulating activity. Further studies are warranted to understand the clinical implication in terms of cancer recurrence.
