The Impact of Optimism on Cancer-Related and Postsurgical Cancer Pain: A Systematic Review

The risk of cognitive decline and dementia in older adults diagnosed with COVID-19: A systematic review and meta-analysis

BACKGROUND

Cognitive impairment can be caused by infections with various pathogens, including SARS-CoV-2. Research has yet to determine the true incidence and course of cognitive impairment in older adults following COVID-19. Furthermore, research has theorised that COVID-19 is associated with dementia progression and diagnosis but this association has yet to be fully described.

METHODS

A systematic review was registered in Prospero and conducted on the databases PubMed, Embase, Ovid, CENTRAL and Cochrane Library. Studies reporting cognitive impairment and dementia outcomes in post-acute and post-COVID-19 patients aged ≥65 years, and which included control data, were included in this review.

RESULTS

15,124 articles were identified by the search strategy. After eliminating duplicate titles and completing title, abstracts and full-text review, 18 studies were included comprising of 412,957 patients with COVID-19 (46.63 % male) and 411,929 patients without COVID-19 (46.59 % male). The overall mean Montreal Cognitive Assessment (MoCA) score in COVID-19 patients was 23.34 out of 30 (95 % CI [22.24, 24.43]). indicating cognitive impairment. The overall proportion of patients identified as having new onset cognitive impairment was 65 % (95 % CI [44,81]). Subgroup analyses indicated that time since infection significantly improves overall MoCA score and reduces proportion of patients with cognitive impairment.

CONCLUSION

This study indicates that cognitive impairment may be an important sequela of COVID-19. Further research with adequate sample sizes is warranted regarding COVID-19's association with new-onset dementia and dementia progression, and the effect of repeat infections. There is a need for development of diagnostic and management protocols for COVID-19 patients with cognitive impairment.

Body appreciation is associated with optimism/pessimism in patients with chronic kidney disease: Results from a cross-sectional study and validation of the Arabic version of the Optimism-Pessimism Short Scale-2

BACKGROUND

Chronic Kidney Disease (CKD) patients encounter many obstacles that affect their physical and psychological well-being. The primary objective of the present study was to investigate potential correlates of optimism/pessimism in a sample of patients with CKD, including socio-demographics, body appreciation and disordered eating symptoms. As a secondary objective, we proposed to examine the psychometric properties of an Arabic translation of the Optimism-Pessimism Short Scale-2 (SOP2) before its use in our sample.

METHODS

A cross-sectional study was carried out between April and May 2023, enrolling 108 participants from three hospitals in Lebanon providing insights into their sociodemographic characteristics, physical activity levels, body appreciation, optimism, pessimism, and eating attitudes.

RESULTS

Results indicated that the Arabic-language adaptation of the SOP2 has good reliability coefficients. The two facets of the scale displayed a strong correlation to each other, and highly similar correlations with external study variables (i.e., household crowding index, physical activity, body appreciation, disordered eating), suggesting that the SOP2 can be interpreted as a unidimensional measure for the psychological dispositional optimism as proposed by the developers. Furthermore, findings revealed a strong positive correlation between body appreciation and optimism, suggesting that CKD patients who appreciate their bodies tend to exhibit a more optimistic outlook on life. Conversely, higher body appreciation is associated with lower pessimism, indicating that a positive body image may mitigate feelings of hopelessness and despair in CKD patients.

CONCLUSION

This study contributes to the literature in two ways. First, it offers the Arabic SOP2 as an brief tool to administer, and psychometrically sound instrument that can be useful for clinical and research purposes. Second, it unveils a clear correlation between higher body appreciation and a more optimistic, less pessimistic mindset in patients with CKD.

Perceptions and Expectations: A Study on Prognostic Perception and Quality of Life in Patients With Metastatic Renal and Bladder Cancer

PURPOSE

Durable complete response rates for metastatic renal cell carcinoma (mRCC) and metastatic bladder cancer (mBC) are low despite new therapy. Palliative care focuses on life extension and quality of life (QoL), not cure. This study aims to investigate patients' perceptions of treatment outcomes in mRCC and mBC and to assess the influence of QoL and optimism levels on these perceptions.

METHODS

From March 15, 2023, to January 15, 2024, a multicenter, cross-sectional online survey was carried out, targeting patients diagnosed with mRCC and mBC. The survey comprised structured questions aimed at evaluating perceptions concerning disease cure, symptom improvement, daily activity performance, and life extension due to treatment. Additionally, to evaluate optimism and QoL, the European Organization for Research and Treatment of Cancer 30.3 QoL questionnaire and life orientation test were implemented. Study on patients' perceptions of treatment outcomes in metastatic kidney and bladder cancer shows high optimism, inaccurate cure beliefs.

RESULTS

In total, 169 patients participated in the survey; the majority of the patients stated their general health status as good (72.2%) and excellent (13.6%). Patients who rated their overall health status as good-excellent had a higher median general QoL and optimism score compared with those who rated it as fair-poor. In all, 85.2% of patients considered the possibility of a cure very likely or likely. Most participants believed treatment could provide symptom relief (30.2% very likely, 49.1% likely), enhanced ability to perform daily activities (28.4% very likely, 55.6% likely), and life extension (32.5% very likely, 53.3% likely). Patients responding very likely and likely to these questions regarding treatment outcomes had higher QoL and optimism scores than those responding a little likely and not possible.

CONCLUSION

The majority of patients with mRCC and mBC held inaccurate beliefs about treatment outcomes. Better QoL and optimism were associated with increased inaccuracy.

Beyond surgery: Overcoming postoperative depression in cancer patients

Depression is a common occurrence among cancer patients, and it significantly impacts their clinical outcomes and quality of life, with a high incidence during anti-tumor treatment or after surgery. The association between surgery and depression is the result of the interaction of various factors, including physiological, psychological, and social factors, all of which are intertwined and make patients susceptible to depression after surgical treatment. Postoperative depression has a significant negative impact on many aspects of cancer patients, and it requires timely identification and intervention to improve the overall outcome.

Clinical observation of the treatment of refractory cancer pain with cancer pain information platform and IDDS under home analgesia mode: A retrospective study

To evaluate the effectiveness and safety of a cancer pain information platform combined with semi-implantable intrathecal drug delivery systems among the patients with refractory cancer pain under a "home analgesia" model. This was a retrospective study. A total of 49 patients underwent semi-implantable intrathecal drug delivery systems with patient-controlled analgesia in conjunction with the establishment of a cancer pain information platform. Numeric rating scales (NRS), Bruggrmann comfort scale (BCS), high-quality sleep duration, and opioid-related adverse effects were recorded at various time points and analyzed: the day on admission (T0), the day of discharge (T1), 30 days post-discharge (T2), 60 days post-discharge (T3), 90 days post-discharge (T4), 120 days post-discharge (T5), 150 days post-discharge (T6), 180 days post-discharge (T7), and the day before death (T8). Compared with T0, NRS significantly decreased and BCS significantly increased at T1 to T8 time points (P < .05). However, NRS and BCS did not show differences at T1 to T8 time points (P > .05). The duration of high-quality sleep was significantly extended, and the incidence of opioid-related adverse effects was significantly reduced. Postoperative complications included 1 case of cerebrospinal fluid leakage, 3 cases of infection at the butterfly needle insertion site, 6 cases of hospital readmission for equipment malfunction, and no cases of respiratory depression. Eleven patients continued standardized antitreatment after IDDS surgery. The mean survival time for all patients was 135.51 ± 102.69 days, and the survival rate at T7 was 30.61%. The cancer pain information platform combined with semi-implantable IDDS is beneficial for the pain management of refractory cancer patients under the "home analgesia" model, improving their quality of life.

Efficacy and safety of crizotinib in the treatment of advanced non-small cell lung cancer with ROS1 gene fusion: a systematic literature review and meta-analysis of real-world evidence

BACKGROUND

Crizotinib was approved to treat patients with advanced non-small cell lung cancer (aNSCLC) with ROS proto-oncogene 1 (ROS1) gene fusion in 2016. We conducted a systematic literature review to identify real-world evidence (RWE) studies and estimated the efficacy and safety of crizotinib using meta-analyses (MA) for objective response rate (ORR), real-world progression-free survival (PFS), and overall survival (OS).

METHODS

We searched MEDLINE®, Embase, and Cochrane CENTRAL from January 2016 to March 2023 using Ovid® for published single-arm or comparative RWE studies evaluating patients (N ≥ 20) receiving crizotinib monotherapy for aNSCLC with ROS1 gene fusion. Pooled estimates for ORR and grade 3/4 adverse events (AEs) were derived using the metafor package in R while pooled estimates for median real-world PFS (rwPFS) and OS were derived using reconstructed individual patient data from published Kaplan-Meier curves. The primary analysis included all studies regardless of crizotinib line of therapy; a subgroup analysis (SA) was conducted using studies evaluating patients receiving first-line crizotinib.

RESULTS

Fourteen studies met the eligibility criteria and were considered feasible for MA. For the primary analysis, the pooled ORR (N = 9 studies) was 70.6 % (95 % confidence interval [CI]: 57.0, 81.3), median rwPFS was 14.5 months (N = 11 studies), and OS was 40.2 months (N = 9 studies). In the SA, the pooled ORR (N = 4 studies) was 81.1 % (95 % CI: 76.1, 85.2) and the median rwPFS (N = 4 studies) and OS (N = 2 studies) were 18.1 and 60 months, respectively. All MAs were associated with significant heterogeneity (I2 > 25 %). Grade 3/4 AEs occurred in 18.7 % of patients (pooled estimate).

CONCLUSION

The results from this study are consistent with clinical trial data and, taken collectively, supports crizotinib as a safe and effective treatment across different lines of therapy in patients with ROS1 aNSCLC in the real-world setting.

A perspective on a precision approach to pain in cancer; moving beyond opioid therapy

PURPOSE

Cancer-related pain is primarily treated with opioids which while effective can add significant patient burden due to side effects, associated stigma, and timely access. The purpose of this perspective discussion is to argue for a precision approach to pain in cancer based on a biopsychosocial and spiritual model which we argue can offer a higher quality of life while limiting opioid use.

CONCLUSIONS

Pain in cancer represents a heterogenous process with multiple contributing and modulating factors. Specific characterization of pain as either nociceptive, neuropathic, nociplastic, or mixed can allow for targeted treatments. Additional assessment of biopsychosocial and spiritual issues can elucidate further points of targeted intervention which can lead to overall greater pain control.

Chronic Pain, Hopelessness, and Suicide Risk Among Adult Medical Inpatients

BACKGROUND

Medically ill adults are at elevated risk for suicide. Chronic pain and hopelessness are associated with suicide; however, few studies have examined the interaction between chronic pain and hopelessness in predicting suicide risk among hospitalized adults.

OBJECTIVE

This study aimed to describe the association between chronic pain, hopelessness, and suicide risk, defined as recent suicidal ideation or lifetime suicidal behavior. In addition, we examined the interaction between chronic pain and hopelessness.

METHODS

This was a secondary analysis of a multisite study to validate the Ask Suicide-Screening Questions (ASQ) among adult medical inpatients. Participants reported if they experienced chronic pain that impacted daily life and if they felt hopeless about their medical condition and provided their current pain rating on a 1 to 10 scale, with 10 being the most severe pain. A t-test compared pain severity scores by ASQ outcome. A binary logistic regression model described the association between chronic pain, hopelessness, and suicide risk; parameter estimates are expressed as odds ratios (OR) for interpretation. The interaction between chronic pain and hopelessness was examined in both the transformed (logit) and natural (probability) scales of the generalized linear model.

RESULTS

The sample included 720 participants (53.2% male, 62.4% White, mean age: 50.1 [16.3] years, range = 18-93). On the ASQ, 15.7% (113/720) of patients screened positive. Half (360/720) of the sample self-reported chronic pain. Individuals who screened positive had higher pain rating scores than those who screened negative (t = -4.2, df = 147.6, P < 0.001). Among all patients, 27.2% (196/720) felt hopeless about their medical condition. In the logistic regression model, patients with chronic pain (adjusted OR: 2.29, 95% confidence interval [CI]: 1.21-4.43, P = 0.01) or hopelessness (adjusted OR: 5.69, 95% CI: 2.52-12.64, P < 0.001) had greater odds of screening positive on the ASQ. The interaction effect between pain and hopelessness was not significant in the transformed (B = -0.15, 95% CI: -1.11 to 0.82, P = 0.76) or natural (B = 0.08, 95% CI: -0.07 to 0.23, P = 0.28) scale.

CONCLUSIONS

There were significant independent associations between (1) chronic pain and suicide risk and between (2) hopelessness and suicide risk. Future research should examine the temporality and mechanisms underlying these relationships to inform prevention efforts for medically ill adults.

The relation of dietary protein intake before and during the pregnancy with gestational diabetes mellitus (GDM): A GRADE-assessed systematic review and dose-response meta-analysis of epidemiologic studies

BACKGROUND

Although previous studies investigated the relation of protein intake and gestational diabetes mellitus (GDM), their findings were controversial. Therefore, we aimed to summarize this association, through a comprehensive systematic review and dose-response meta-analysis.

METHODS

Electronic databases including MEDLINE (PubMed), ISI Web of Science, Scopus and motor engineering of Google Scholar were systematically searched up to April 2023. Observational studies which investigated odds of GDM in relation to protein intake were included.

RESULTS

A total of 31,005 participants with 3451 cases of GDM from 13 eligible investigations were included in the systematic review and meta-analysis. Comparing the highest and lowest intakes of total, animal, and plant proteins revealed the summary RRs of 1.82 (95% CI: 1.42, 2.33), 1.79 (95% CI: 1.50, 2.14), and 0.98 (95% CI: 0.81, 1.20), respectively, indicating a significant positive association between total and animal protein intake and GDM. In the dose-response analyses, each 5% increment in energy intake from total protein during pregnancy was related to 20% increased odds of GDM (RR = 1.20; 95% CI: 1.09, 1.33). In the non-linear dose-response analyses, we found a non-linear association for animal protein intake during pregnancy (P for non-linearity <0.001); so that, a risk increase was seen from zero to 10% of energy intake from animal proteins, however, a risk reduction was seen after 10% of energy intake. However, there was not any significant non-linear trend between plant protein intake during pregnancy and risk of GDM. Based on the GRADE assessment, the quality of evidence for total, animal and plant protein was rated as "moderate", "moderate" and "very low", respectively.

CONCLUSION

We found a significant positive association between total protein intake and GDM; however, the associations of animal and plant protein intake with GDM were dose-dependent.

Risk of death and readmission among individuals with heart failure and HIV: A systematic review and meta-analysis

The association between human immunodeficiency virus (HIV) status and readmissions and death outcomes in patients with established heart failure (HF) remains unclear. We conducted a systematic search of PubMed, EMBASE, Cochrane Library, and Web of Science up to March 1st, 2023, for cohort studies of adult patients (≥18 years) diagnosed with HF and recorded HIV status at baseline. Our analysis included 7 studies with 10,328 HF patients living with HIV and 48,757 HF patients without HIV. Compared to HF patients without HIV, those with HIV had a higher risk of all-cause deaths (HR: 1.20, 95% CI: 1.15-1.25). HIV infection was also associated with increased risks of HF-associated readmission (HR: 1.34, 95% CI: 1.03-1.75) and all-cause readmission (HR: 1.27, 95% CI: 1.10-1.46). Our study highlights the independent association between HIV and poor HF outcomes, emphasizing the need for improved management in individuals living with HIV.

Pelvic floor dysfunction after colorectal cancer treatment is related to physical and psychological health and body image: A cross-sectional study

PURPOSE

Pelvic floor dysfunction (PFD) often occurs in patients with colorectal cancer (CRC), which can affect their quality of life. However, the precise factors that related to PFD in CRC patients remain elusive. The main objective of this study was to identify the variables associated with PFD following CRC treatment and establish a foundation for the development of a tailored rehabilitation plan specific to this population.

METHODS

The classification of 149 patients with CRC was conducted according to the type of medical treatment they underwent. PFD was evaluated using the Urogenital Distress Inventory 6 (UDI-6) and Colorectal-Anal Distress Inventory 8 (CRADI-8) questionnaires. The study employed the Short form 36 health survey (SF-36) and Body Image Scale (BIS) to evaluate physical and psychological health as well as body image disorders. The connection between PFD and independent variables was determined through logistic regression analyses.

RESULTS

Of all patients, more than 50% reported experiencing dysfunction, with the highest proportion observed in the PRT (primary radiotherapy) group. The LRR/RR (robotic-assisted colorectal resection or laparoscopic colorectal resection) group revealed a significant association between high BMI (Body Mass Index) and alcohol consumption with PFD. Moreover, in the PRT group, PFD was correlated with poorer physical condition (OR = 0.94, 95% CI = [0.88-1.00]).

CONCLUSIONS

PFD is a commonly complained-about issue among patients with CRC. Early intervention targeted towards these factors may aid in the alleviation of associated distress and contribute towards the individualization of CRC rehabilitation programs, consequently improving the quality of life for patients.

Prognostic models for chronic postsurgical pain-Current developments, trends, and challenges

PURPOSE OF REVIEW

Prognostic models for chronic postsurgical pain (CPSP) aim to predict the likelihood for development and severity of CPSP in individual patients undergoing surgical procedures. Such models might provide valuable information for healthcare providers, allowing them to identify patients at higher risk and implement targeted interventions to prevent or manage CPSP effectively. This review discusses the latest developments of prognostic models for CPSP, their challenges, limitations, and future directions.

RECENT FINDINGS

Numerous studies have been conducted aiming to develop prognostic models for CPSP using various perioperative factors. These include patient-related factors like demographic variables, preexisting pain conditions, psychosocial aspects, procedure-specific characteristics, perioperative analgesic strategies, postoperative complications and, as indicated most recently, biomarkers. Model generation, however, varies and performance and accuracy differ between prognostic models for several reasons and validation of models is rather scarce.

SUMMARY

Precise methodology of prognostic model development needs advancements in the field of CPSP. Development of more accurate, validated and refined models in large-scale cohorts is needed to improve reliability and applicability in clinical practice and validation studies are necessary to further refine and improve the performance of prognostic models for CPSP.

Identifying risk factors for chronic postsurgical pain and preventive measures: a comprehensive update

INTRODUCTION

Chronic postsurgical pain (CPSP) is a prevalent condition that can diminish health-related quality of life, cause functional deficits, and lead to patient distress. Rates of CPSP are higher for certain types of surgeries than others (thoracic, breast, or lower extremity amputations) but can occur after even uncomplicated minimally invasive procedures. CPSP has multiple mechanisms, but always starts as acute postsurgical pain, which involves inflammatory processes and may encompass direct or indirect neural injury. Risk factors for CPSP are largely known but many, such as female sex, younger age, or type of surgery, are not modifiable. The best strategy against CPSP is to quickly and effectively treat acute postoperative pain using a multimodal analgesic regimen that is safe, effective, and spares opioids.

AREAS COVERED

This is a narrative review of the literature.

EXPERT OPINION

Every surgical patient is at some risk for CPSP. Control of acute postoperative pain appears to be the most effective approach, but principles of good opioid stewardship should apply. The role of regional anesthetics as analgesics is gaining interest and may be appropriate for certain patients. Finally, patients should be better informed about their relative risk for CPSP.

The role of optimism in manifesting recovery outcomes after coronary artery bypass graft surgery: A systematic review

OBJECTIVE

Coronary artery bypass graft (CABG) is a major surgery conducted in coronary heart disease management. Postoperative recovery is a crucial process for patients undergoing CABG. This systematic review evaluates current evidence regarding the association between trait optimism and recovery outcomes in patients following coronary artery bypass graft surgery.

METHODS

This review followed the Preferred Reporting Items of Systematic Review and Meta-Analysis (PRISMA) 2020 Guideline. The inclusion criteria focused on observational study that examined study participants aged ≥18 years old undergoing elective CABG and measurement of trait optimism with validated methods (i.e. LOT, LOT-R) and at least one recovery outcome. Studies in non-English languages and duplicates were excluded. A systematic literature search was carried out on PubMed, Scopus, and Web of Science electronic databases. Search results were screened based on the eligibility criteria. The Newcastle-Ottawa Scale was used to assess the quality of each included study.

RESULTS

The search yielded a total of 1853 articles, in which 7 articles fulfilled the eligibility criteria and were subsequently included in the analysis. Measurement of trait optimism was conducted on 1276 patients who underwent a non-emergency/elective CABG. Optimism was significantly associated with several categories of recovery, including reduced rehospitalization rate, complications, pain, and physical symptoms along with improved quality of life, rate of return to normal life, and psychological status.

CONCLUSION

Our review showed that trait optimism was associated with recovery outcomes following CABG surgery. However, the heterogeneity of recovery outcomes may hamper the clinical benefit of trait optimism in CABG. (PROSPERO CRD42022301882).
