Coping Strategies and Associated Symptom Burden Among Patients With Advanced Cancer.

BACKGROUND: Few studies examine how patients with advanced cancer cope with stress. The objective of our study was to evaluate coping strategies adopted by patients with cancer and their relationship with symptom burden. METHODS: A secondary data analysis of a prospective cross-sectional survey of patients with cancer and tobacco use was conducted, which examined demographics, symptom burden (Edmonton Symptom Assessment System), and coping strategies (the Brief COPE Questionnaire). Demographic characteristics were summarized by standard summary statistics; we also examined associations between patient characteristics and coping strategies using t-test, rank-sum test, chi-squared test, or Fisher's exact test depending on the distribution of data. RESULTS: Among 399 patients, the majority were female (60%), Caucasian (70%), the mean age was 56.5 (±12.0) years, and the most common malignancies were gastrointestinal (21%) and breast (19%). Patients with cancer adopted multiple adaptive coping strategies, most frequently acceptance (86.7%) and emotional support (79.9%), with humor (18.5%) being the least. Common maladaptive strategies included venting (14.5%) and self-distraction (36.6%), while substance use (1.0%) was infrequently reported. Of the adaptive strategies, female gender was significantly associated with higher engagement with emotional and instrumental support, positive reframing, religious coping, and acceptance (P < .05 for all). College educated patients reported significantly higher implementation of humor, planning, and acceptance. Maladaptive coping strategies such as denial were associated with increased pain and depression, while patients adopting emotional-focused strategies rated decreased emotional distress. CONCLUSIONS: The majority of patients with advanced cancer reported adopting multiple, adaptive coping strategies, and a minority utilized maladaptive or avoidant strategies, rarely substance use, and may need additional psychological support.

Differences in PPD- and mitogen-induced T-cell activation marker expression characterize immunopathology in acute tuberculosis patients.

Impaired T-cell responses to mitogens and high T-cell activation marker (TAM) expression on Mycobacterium tuberculosis-specific T-cells characterize immunopathology in patients with tuberculosis (TB). In a study of patients with TB (n = 60) and asymptomatic contacts (controls, n = 37), we found that TB patients had higher CD38+ T-cell proportions specific for M. tuberculosis protein (PPDMtb), yet total proportions of PPDMtb-specific T-cells were comparable. Notably, both activated (CD38+) and total IFN-γ+ T-cells from TB patients had lower mitogen (phytohemagglutinin, PHA)-induced responses. This impaired mitogen response improved the classification efficacy of the TAM-TB assay, especially employing the PPD/PHA-induced T-cell ratio.

Healthcare provider perceptions and reported practices regarding opioid prescription for patients with chronic cancer pain.

PURPOSE: Data indicates that clinicians might be under-prescribing opioids for patients with chronic cancer pain, and this could impact adequate pain management. Few studies have sought to understand healthcare provider (HCP) perceptions and practices regarding the prescription of opioids for chronic cancer pain. We assessed HCP perceptions and practices regarding opioid prescription for patients with chronic cancer pain since the onset of the COVID-19 pandemic. METHODS: An anonymous cross-sectional survey was conducted among 186 HCPs who attended an opioid educational event in April 2021 and 2022. RESULTS: Sixty-one out of 143 (44%) opioid prescribers reported reluctance to prescribe opioids for chronic cancer pain. In a multivariate logistic model, younger participants (log OR - 0.04, 95% CI - 0.085, - 0.004; p = 0.033) and pain medicine clinicians (log OR - 1.89, CI - 3.931, - 0.286; p = 0.034) were less reluctant, whereas providers who worry about non-medical opioid use were more reluctant to prescribe opioids (log OR 1.58 95% CI 0.77-2.43; p < 0.001). Fifty-three out of 143 (37%) prescribers had experienced increased challenges regarding opioid dispensing at pharmacies, and 84/179 (47%) of all respondents reported similar experience by their patients. Fifty-four out of 178(30%) were aware of opioid-related harmful incidents to patients or their families, including incidents attributed to opioid misuse by a household or family member. CONCLUSION: A considerable number of opioid prescribers were reluctant to prescribe opioids for patients with chronic cancer pain. Many reported challenges regarding dispensing of opioids at the pharmacies. These may be unintended consequences of policies to address the opioid crisis. Future measures should focus on addressing regulatory barriers without undermining the gains already made to combat the opioid crisis.

Monocyte pathology in human tuberculosis is due to plasma milieu changes and aberrant STAT signalling.

Monocyte-derived macrophages contribute centrally to immune protection in Mycobacterium tuberculosis infection and changes in monocyte phenotype characterize immunopathology in tuberculosis patients. Recent studies highlighted an important role of the plasma milieu in tuberculosis immunopathology. Here, we investigated monocyte pathology in patients with acute tuberculosis and determined tuberculosis plasma milieu effects on phenotype as well as cytokine signalling of reference monocytes. Patients with tuberculosis (n = 37) and asymptomatic contacts (controls n = 35) were recruited as part of a hospital-based study in the Ashanti region of Ghana. Multiplex flow cytometry phenotyping of monocyte immunopathology was performed and effects of individual blood plasma samples on reference monocytes prior to and during treatment were characterized. Concomitantly, cell signalling pathways were analysed to elucidate underlying mechanisms of plasma effects on monocytes. Multiplex flow cytometry visualization characterized changes in monocyte subpopulations and detected higher expression of CD40, CD64 and PD-L1 in monocytes from tuberculosis patients as compared to controls. Aberrant expression normalized during anti-mycobacterial treatment and also CD33 expression decreased markedly. Notably, higher CD33, CD40 and CD64 expression was induced in reference monocytes when cultured in the presence of plasma samples from tuberculosis patients as compared to controls. STAT signalling pathways were affected by the aberrant plasma milieu and higher levels of STAT3 and STAT5 phosphorylation was found in tuberculosis plasma-treated reference monocytes. Importantly, high pSTAT3 levels were associated with high CD33 expression and pSTAT5 correlated with CD40 as well as CD64 expression. These results suggested plasma milieu effects with potential implications on monocyte phenotype and function in acute tuberculosis.

Cytokine-induced transient monocyte IL-7Ra expression and the serum milieu in tuberculosis.

Bacterial components and cytokines induce IL-7 receptor (IL-7Rα) expression in monocytes. Aberrant low IL-7Rα expression of monocytes has been identified as a feature of tuberculosis immunopathology. Here, we investigated the mechanisms underlying IL-7Rα regulation of monocytes and tuberculosis serum effects on IL-7Rα expression. Serum samples from tuberculosis patients and healthy controls, cytokine candidates, and mycobacterial components were analyzed for in vitro effects on IL-7Rα expression of primary monocytes, monocyte-derived macrophages (MDM), and monocyte cell lines. IL-7Rα regulation during culture and the role of FoxO1 were characterized. In vitro activation-induced IL-7Rα expression in human monocytes and serum samples from tuberculosis patients boosted IL-7Rα expression. Although pathognomonic tuberculosis cytokines were not associated with serum effects, we identified cytokines (i.e., GM-CSF, IL-1ß, TNF-α, IFN-γ) that induced IL-7Rα expression in monocytes and/or MDM comparable to mycobacterial components. Blocking of cytokine subsets (i.e., IL-1ß/TNF-α in monocytes, GM-CSF in MDM) largely diminished IL-7Rα expression induced by mycobacterial components. Finally, we showed that in vitro-induced IL-7Rα expression was transient and dependent on constitutive FoxO1 expression in primary monocytes and monocyte cell lines. This study demonstrated the crucial roles of cytokines and constitutive FoxO1 expression for transient IL-7Rα expression in monocytes.

Impaired T-cell response to phytohemagglutinin (PHA) in tuberculosis patients is associated with high IL-6 plasma levels and normalizes early during anti-mycobacterial treatment.

PURPOSE: Human tuberculosis is characterized by immunopathology that affects T-cell phenotype and functions. Previous studies found impaired T-cell response to phytohemagglutinin (PHA) in patients with acute tuberculosis. However, the influence of disease severity, affected T-cell subsets, and underlying mechanisms remain elusive. METHODS: Here we investigated PHA-induced and antigen-specific T-cell effector cytokines in tuberculosis patients (n = 55) as well as in healthy asymptomatic contacts (n = 32) from Ghana. Effects of Mycobacterium (M.) tuberculosis sputum burden and treatment response were analyzed and compared during follow-up. Finally, cytokine characteristics of the aberrant plasma milieu in tuberculosis were analyzed as a potential cause for impaired PHA response. RESULTS: PHA-induced IFN-γ expression was significantly lower in sputum-positive tuberculosis patients as compared to both, contacts and paucibacillary cases, and efficiently discriminated the study groups. T-cell responses to PHA increased significantly early during treatment and this was more pronounced in tuberculosis patients with rapid treatment response. Analysis of alternative cytokines revealed distinct patterns and IL-22, as well as IL-10, showed comparable expression to IFN-γ in response to PHA. Finally, we found that high IL-6 plasma levels were strongly associated with impaired IFN-γ and IL-22 response to PHA. CONCLUSION: We conclude that impaired T-cell response to PHA stimulation in acute tuberculosis patients (i) was potentially caused by the aberrant plasma milieu, (ii) affected differentially polarized T-cell subsets, (iii) normalized early during treatment. This study shed light on the mechanisms of impaired T-cell functions in tuberculosis and yielded promising biomarker candidates for diagnosis and monitoring of treatment response.

Plasma cytokine levels characterize disease pathogenesis and treatment response in tuberculosis patients.

BACKGROUND: Mycobacterium (M.) tuberculosis-caused immunopathology is characterized by aberrant expression of plasma cytokines in human tuberculosis. Disease severity and long-term anti-mycobacterial treatment are potentially influenced by immunopathology and normalization of plasma cytokine levels during therapy may indicate treatment efficacy and recovery. STUDY DESIGN AND METHODS: In this study, we analyzed the concentrations of selected plasma cytokines (i.e., IL-6, IP-10, IL-10, IL-22, IFNγ, GM-CSF, IL-8) and M. tuberculosis sputum burden in patients with tuberculosis (n = 76). Cytokine levels were compared to healthy contacts (n = 40) and changes under treatment were monitored (i.e., 6 and 16 weeks after treatment start). According to differences in M. tuberculosis sputum burden and conversion, tuberculosis patients were classified as paucibacillary as well as 'rapid' or 'slow' treatment responders. A subgroup of tuberculosis patients had fatal disease courses. RESULTS: Six of seven cytokines were significantly higher in tuberculosis patients as compared to contacts and four of these (i.e., IL-6, IP-10, IL-10, and IL-22) were detectable in the majority of tuberculosis patients. IL-6 showed the strongest discriminating capacity for tuberculosis disease and in combination with IL-10 concentrations efficiently classified paucibacillary tuberculosis cases as well as those with fatal disease outcome. In addition, IL-6 and IP-10 levels decreased significantly after 6 weeks of treatment and analyses of subgroups with differential treatment response showed delayed decline of IL-6 levels in slow treatment responders. CONCLUSIONS: Combinations of different plasma cytokine (namely, IL-6, IL-10, and IP-10) efficiently classified tuberculosis patients with differential mycobacterial burden and especially IL-6 qualified as a biomarker candidate for early treatment response.

Nonmedical opioid use at the end of life: A tale of addiction and a last wish.

BACKGROUND: Nonmedical opioid use (NMOU) has been associated with opioid overdose deaths. This pattern of misuse can be seen in those using opioids for cancer-associated pain. We present a case that highlights the complexities associated with NMOU and a patient's care at the end of life. CASES DESCRIPTION: A patient with a metastatic solid tumor malignancy along with co-occurring history of polysubstance abuse was admitted to an acute palliative and supportive care unit (APSCU). The patient demonstrated behaviors concerning for NMOU during her hospital stay but had increased symptom expression concerning for worsening dyspnea while in the APSCU. Unfortunately, she used home opioids, which was unknown to the team at the time along with requesting for higher doses of opioids that were being prescribed. This caused a worsening respiratory status and affected her care. Using an interdisciplinary approach, the providers managed her symptoms and discharged her safely to see her child. CONCLUSION: This highlights the complexities of the alleviation of suffering in those with NMOU. It is important to continue to manage NMOU at the end of life due to its effects on quality of life. A multimodal approach is recommended to identify and care for these patients.

Reliability of urine drug testing among patients on buprenorphine transdermal patch.

BACKGROUND: Urine drug testing (UDT) plays a significant role in monitoring patients on chronic opioid therapy (COT) for non-medical opioid use (NMOU). UDT, at times, can be inconsistent and misleading. We present a case where a patient on a buprenorphine patch had false negative results. CASE DESCRIPTION: A female in her 70s with metastatic breast cancer presented with uncontrolled pain from a T6 compression fracture. She had no relief with tramadol 50 mg every 6 hours as needed. Due to an allergic reaction to hydromorphone, our team prescribed a buprenorphine patch of 5 µg/h. Subsequently, she expressed excellent pain control, and the clinician confirmed the patch placement on examination. She underwent a UDT during the visit. The UDT was negative for both buprenorphine and its metabolites. The literature review showed that false negative UDT results are relatively common among patients with low-dose buprenorphine patches. The combination of a thorough physical examination, a review of the Prescription Drug Monitoring Program, and reassuring scores on screening tools placed her at low risk for NMOU. DISCUSSION: Buprenorphine has a ceiling effect on respiratory depression and a lower risk for addiction. However, when used in low doses, the drug might not have enough metabolites in the urine, leading to a false negative UDT. Such results might affect patient-physician relationships. CONCLUSION: In addition to the UDT, a thorough history, screening for NMOU, physical exam, a review of PDMP, and a good understanding of opioid metabolism are necessary to help guide pain management.

Assessing risk for nonmedical opioid use among patients with cancer: Stability of the CAGE-AID questionnaire across clinical care settings.

OBJECTIVES: The Cut down, Annoyed, Guilty, and Eye opener- Adapted to Include Drugs (CAGE-AID) questionnaire (CA) is a validated screening tool used to assess risk for nonmedical opioid use (NMOU) in patients receiving opioids for cancer pain. Data on consistencies and variations in responses to the CA between different clinical settings are lacking. We evaluated the frequency and consistency in scoring of the CA among patients seen between the first inpatient consult (T1) and the first outpatient follow-up (T2) visits. METHODS: A retrospective chart review of 333 consecutive patients seen at both T1 and T2 within 3 months between August 2016 and March 2017 was reviewed. RESULTS: Median age was 58 years (range, 18-87 years); 53% were female. CA was completed for 88% of patients at T1 and 94% at T2. Of these, 10% and 13% were CAGE-AID positive, respectively. CA score changed from negative to positive in 4% and from positive to negative in 1% of patients between T1 and T2. Kappa coefficient for agreement of CA between T1 and T2 was 0.74 (95% CI: 0.62-0.86, p = 0.02). SIGNIFICANT OF RESULTS: Completion rate and consistency of patient responses to the CA were high irrespective of clinical setting. Of these patients, 10% and 13% were CA positive which is suggestive of high risk for NMOU. Further studies are needed to evaluate ways to ensure more consistency in the completion of the CA and enhance its utilization in routine clinical practice.

Interdisciplinary intervention for the management of nonmedical opioid use among patients with cancer pain.

BACKGROUND: Few studies have assessed interventions aimed at managing nonmedical opioid use (NMOU) behavior among patients with cancer. The authors developed the Compassionate High-Alert Team (CHAT) intervention to manage patients receiving opioids for cancer pain who demonstrate NMOU behavior. The objective of this study was to determine the change in frequency of NMOU behaviors, pain intensity, and opioid requirements among those who received the intervention. METHODS: A total of 130 patients receiving opioids for cancer pain that had documented evidence of NMOU and received the CHAT intervention were reviewed. Demographic and clinical information such as NMOU behaviors, pain scores, and morphine equivalent daily dose at baseline, 3, and 6 months post-intervention was obtained. RESULTS: NMOU behaviors significantly decreased from a median (interquartile range) of 2 (1-3) at baseline to 0 (0-1) at both 3 and 6 months post-intervention (p < .001). A total of 45 of 75 (60%) and 31 of 50 (62%) of CHAT recipients achieved complete response to the intervention at 3 and 6 months, respectively. Higher baseline number of NMOU behaviors was independently associated with patient response to the intervention (odds ratio [OR], 1.97; 95% confidence interval [CI],1.09-4.28, p = .049 at 3 months; OR, 2.5; 95% CI, 1.20-6.47, p = .03 at 6 months). The median pain score decreased from 7 at baseline to 6 at both 3 and 6 months (p = .01). Morphine equivalent daily dose did not significantly change during that same period (143 mg/day vs. 139 mg/day, p = .13). CONCLUSIONS: Most patients who received the CHAT intervention improved in their NMOU behaviors and pain intensity scores 3 and 6 months post-intervention. These preliminary findings support the efficacy of CHAT in managing patients receiving opioids for cancer pain who demonstrate NMOU behavior.

Comprehensive, integrated, and phased whole-genome analysis of the primary ENCODE cell line K562.

K562 is widely used in biomedical research. It is one of three tier-one cell lines of ENCODE and also most commonly used for large-scale CRISPR/Cas9 screens. Although its functional genomic and epigenomic characteristics have been extensively studied, its genome sequence and genomic structural features have never been comprehensively analyzed. Such information is essential for the correct interpretation and understanding of the vast troves of existing functional genomics and epigenomics data for K562. We performed and integrated deep-coverage whole-genome (short-insert), mate-pair, and linked-read sequencing as well as karyotyping and array CGH analysis to identify a wide spectrum of genome characteristics in K562: copy numbers (CN) of aneuploid chromosome segments at high-resolution, SNVs and indels (both corrected for CN in aneuploid regions), loss of heterozygosity, megabase-scale phased haplotypes often spanning entire chromosome arms, structural variants (SVs), including small and large-scale complex SVs and nonreference retrotransposon insertions. Many SVs were phased, assembled, and experimentally validated. We identified multiple allele-specific deletions and duplications within the tumor suppressor gene FHIT Taking aneuploidy into account, we reanalyzed K562 RNA-seq and whole-genome bisulfite sequencing data for allele-specific expression and allele-specific DNA methylation. We also show examples of how deeper insights into regulatory complexity are gained by integrating genomic variant information and structural context with functional genomics and epigenomics data. Furthermore, using K562 haplotype information, we produced an allele-specific CRISPR targeting map. This comprehensive whole-genome analysis serves as a resource for future studies that utilize K562 as well as a framework for the analysis of other cancer genomes.

Sequence variants associating with urinary biomarkers.

Urine dipstick tests are widely used in routine medical care to diagnose kidney and urinary tract and metabolic diseases. Several environmental factors are known to affect the test results, whereas the effects of genetic diversity are largely unknown. We tested 32.5 million sequence variants for association with urinary biomarkers in a set of 150 274 Icelanders with urine dipstick measurements. We detected 20 association signals, of which 14 are novel, associating with at least one of five clinical entities defined by the urine dipstick: glucosuria, ketonuria, proteinuria, hematuria and urine pH. These include three independent glucosuria variants at SLC5A2, the gene encoding the sodium-dependent glucose transporter (SGLT2), a protein targeted pharmacologically to increase urinary glucose excretion in the treatment of diabetes. Two variants associating with proteinuria are in LRP2 and CUBN, encoding the co-transporters megalin and cubilin, respectively, that mediate proximal tubule protein uptake. One of the hematuria-associated variants is a rare, previously unreported 2.5 kb exonic deletion in COL4A3. Of the four signals associated with urine pH, we note that the pH-increasing alleles of two variants (POU2AF1, WDR72) associate significantly with increased risk of kidney stones. Our results reveal that genetic factors affect variability in urinary biomarkers, in both a disease dependent and independent context.

Random urine drug testing among patients receiving opioid therapy for cancer pain.

BACKGROUND: There is limited information regarding the true frequency of nonmedical opioid use (NMOU) among patients receiving opioid therapy for cancer pain. Data to guide patient selection for urine drug testing (UDT) as well as the timing and frequency of ordering UDT are insufficient. This study examined the frequency of abnormal UDT among patients with cancer who underwent random UDT and their characteristics. METHODS: Demographic and clinical information for patients with cancer who underwent random UDT were retrospectively reviewed and compared with a historical cohort that underwent targeted UDT. Random UDT was ordered regardless of a patient's risk potential for NMOU. Targeted UDT was ordered on the basis of a physician's estimation of a patient's risk for NMOU. RESULTS: In all, 552 of 573 eligible patients (96%) underwent random UDT. Among these patients, 130 (24%) had 1 or more abnormal results; 38 of the 88 patients (43%) who underwent targeted UDT had 1 or more abnormal results. When marijuana was excluded, 15% of the random group and 37% of the targeted group had abnormal UDT findings (P < .001). It took a shorter time from the initial consultation to detect 1 or more abnormalities with the random test than the targeted test (median, 130 vs 274 days; P = .02). Abnormal random UDT was independently associated with younger age (P < .0001), male sex (P = .03), Cut Down, Annoyed, Guilty, and Eye Opener-Adapted to Include Drugs positivity (P = .001), and higher Edmonton Symptom Assessment System anxiety (P = .01). CONCLUSIONS: Approximately 1 in 4 patients receiving opioids for cancer pain at a supportive care clinic who underwent random UDT had 1 or more abnormalities. Random UDT detected abnormalities earlier than the targeted test. These findings suggest that random UDT is justified among patients with cancer pain.

Haplotype-resolved and integrated genome analysis of the cancer cell line HepG2.

HepG2 is one of the most widely used human cancer cell lines in biomedical research and one of the main cell lines of ENCODE. Although the functional genomic and epigenomic characteristics of HepG2 are extensively studied, its genome sequence has never been comprehensively analyzed and higher order genomic structural features are largely unknown. The high degree of aneuploidy in HepG2 renders traditional genome variant analysis methods challenging and partially ineffective. Correct and complete interpretation of the extensive functional genomics data from HepG2 requires an understanding of the cell line's genome sequence and genome structure. Using a variety of sequencing and analysis methods, we identified a wide spectrum of genome characteristics in HepG2: copy numbers of chromosomal segments at high resolution, SNVs and Indels (corrected for aneuploidy), regions with loss of heterozygosity, phased haplotypes extending to entire chromosome arms, retrotransposon insertions and structural variants (SVs) including complex and somatic genomic rearrangements. A large number of SVs were phased, sequence assembled and experimentally validated. We re-analyzed published HepG2 datasets for allele-specific expression and DNA methylation and assembled an allele-specific CRISPR/Cas9 targeting map. We demonstrate how deeper insights into genomic regulatory complexity are gained by adopting a genome-integrated framework.

The development of a nomogram to determine the frequency of elevated risk for non-medical opioid use in cancer patients.

OBJECTIVE: Non-medical opioid use (NMOU) is a growing crisis. Cancer patients at elevated risk of NMOU (+risk) are frequently underdiagnosed. The aim of this paper was to develop a nomogram to predict the probability of +risk among cancer patients receiving outpatient supportive care consultation at a comprehensive cancer center. METHOD: 3,588 consecutive patients referred to a supportive care clinic were reviewed. All patients had a diagnosis of cancer and were on opioids for pain. All patients were assessed using the Edmonton Symptom Assessment Scale (ESAS), Screener and Opioid Assessment for Patients with Pain (SOAPP-14), and CAGE-AID (Cut Down-Annoyed-Guilty-Eye Opener) questionnaires. "+risk" was defined as an SOAPP-14 score of ≥7. A nomogram was devised based on the risk factors determined by the multivariate logistic regression model to estimate the probability of +risk. RESULTS: 731/3,588 consults were +risk. +risk was significantly associated with gender, race, marital status, smoking status, depression, anxiety, financial distress, MEDD (morphine equivalent daily dose), and CAGE-AID score. The C-index was 0.8. A nomogram was developed and can be accessed at https://is.gd/soappnomogram. For example, for a male Hispanic patient, married, never smoked, with ESAS scores for depression = 3, anxiety = 3, financial distress = 7, a CAGE score of 0, and an MEDD score of 20, the total score is 9 + 9+0 + 0+6 + 10 + 23 + 0+1 = 58. A nomogram score of 58 indicates the probability of +risk of 0.1. SIGNIFICANCE OF RESULTS: We established a practical nomogram to assess the +risk. The application of a nomogram based on routinely collected clinical data can help clinicians establish patients with +risk and positively impact care planning.

Neuroleptic strategies for terminal agitation in patients with cancer and delirium at an acute palliative care unit: a single-centre, double-blind, parallel-group, randomised trial.

BACKGROUND: The role of neuroleptics for terminal agitated delirium is controversial. We assessed the effect of three neuroleptic strategies on refractory agitation in patients with cancer with terminal delirium. METHODS: In this single-centre, double-blind, parallel-group, randomised trial, patients with advanced cancer, aged at least 18 years, admitted to the palliative and supportive care unit at the University of Texas MD Anderson Cancer Center (Houston, TX, USA), with refractory agitation, despite low-dose haloperidol, were randomly assigned to receive intravenous haloperidol dose escalation at 2 mg every 4 h, neuroleptic rotation with chlorpromazine at 25 mg every 4 h, or combined haloperidol at 1 mg and chlorpromazine at 12·5 mg every 4 h, until death or discharge. Rescue doses identical to the scheduled doses were administered at inception, and then hourly as needed. Permuted block randomisation (block size six; 1:1:1) was done, stratified by baseline Richmond Agitation Sedation Scale (RASS) scores. Research staff, clinicians, patients, and caregivers were masked to group assignment. The primary outcome was change in RASS score from time 0 to 24 h. Comparisons among group were done by modified intention-to-treat analysis. This completed study is registered with ClinicalTrials.gov, NCT03021486. FINDINGS: Between July 5, 2017, and July 1, 2019, 998 patients were screened for eligibility, with 68 being enrolled and randomly assigned to treatment; 45 received the masked study interventions (escalation n=15, rotation n=16, combination n=14). RASS score decreased significantly within 30 min and remained low at 24 h in the escalation group (n=10, mean RASS score change between 0 h and 24 h -3·6 [95% CI -5·0 to -2·2]), rotation group (n=11, -3·3 [-4·4 to -2·2]), and combination group (n=10, -3·0 [-4·6 to -1·4]), with no difference among groups (p=0·71). The most common serious toxicity was hypotension (escalation n=6 [40%], rotation n=5 [31%], combination n=3 [21%]); there were no treatment-related deaths. INTERPRETATION: Our data provide preliminary evidence that the three strategies of neuroleptics might reduce agitation in patients with terminal agitation. These findings are in the context of the single-centre design, small sample size, and lack of a placebo-only group. FUNDING: National Institute of Nursing Research.

Urine Drug Testing in Cancer Pain Management.

Urine drug test (UDT) is an effective tool used in chronic opioid therapy to ensure patient adherence to treatment and detect nonmedical opioid use. The two main types of UDT used in routine clinical practice are the screening tests or immunoassays and the confirmatory tests or laboratory-based specific drug identification tests such as gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry, or tandem mass spectrometry. UDT produces objective data on some nonmedical opioid use that may otherwise go undetected, such as the use of undisclosed medications, the nonuse of prescribed medications, and the use of illegal drugs. It allows clinicians to initiate an open and effective conversation about nonmedical opioid use with their patients. However, the test has certain limitations that sometimes compromise its use. Its interpretation can be challenging to clinicians because of the complexity of the opioid metabolic pathways. Clear guidelines or recommendations regarding the use of UDT in cancer pain is limited. As a result, UDT appears to be underused among patients with cancer pain receiving opioid therapy. More studies are needed to help standardize the integration and use of UDT in routine cancer pain management. IMPLICATIONS FOR PRACTICE: Despite its potential benefits, urine drug testing (UDT) appears to be underused among patients with cancer pain receiving opioid therapy. This is partly because its interpretation can be challenging owing to the complexity of the opioid metabolic pathways. Information regarding the use of UDT in opioid therapy among patients with cancer is limited. This review article will improve clinician proficiency in UDT interpretation and assist oncologists in developing appropriate treatment plans during chronic opioid therapy.

Practices and perceptions regarding intravenous opioid infusion and cancer pain management.

BACKGROUND: In view of the recent opioid crisis, ways to promote safe and effective opioid-related practices are needed. Faster intravenous (iv) opioid infusion rates can result in increased adverse effects and risk for nonmedical opioid use. Data on best practices regarding safe iv opioid administration for cancer pain are limited. This study examined iv opioid bolus infusion practices and perceptions about opioids in cancer pain among 4 groups of inpatient oncology nurses. METHODS: An anonymous cross-sectional survey was conducted among oncology nurses working in medical, surgical, intensive care unit (ICU), and emergency department (ED) settings. An iv opioid bolus infusion speed less than 120 seconds was considered too fast. RESULTS: The participant response rate was 59% (731 of 1234). Approximately 58%, 54%, and 58% of all nurses administered morphine, hydromorphone, and fentanyl, respectively, in less than 120 seconds. The median morphine infusion speeds were 55, 60, 60, and 85 seconds for ICU, surgical, ED, and medical unit nurses, respectively (P = .0002). The odds ratios for infusing too fast were 2.04 and 2.52 for ED (P = .039) and ICU nurses (P = .003), respectively, in comparison with medical unit nurses, and they were 0.27 and 0.18 with frequent (P = .003) and very frequent use of a timing device (P = .0001), respectively, in comparison with no use. CONCLUSIONS: More than half the nurses working in the inpatient setting reported administering iv opioids too fast. ICU nurses administered opioids the fastest. Nurses who frequently used a timing device were less likely to infuse too fast. Further research is needed to standardize and improve the safe intermittent administration of iv opioids to patients with cancer.

Concurrent use of opioids with benzodiazepines or nonbenzodiazepine sedatives among patients with cancer referred to an outpatient palliative care clinic.

BACKGROUND: The concurrent use of opioids with benzodiazepines (BZD) or nonbenzodiazepine sedatives (S) recently was found to be associated with an increased risk of overdose death compared with the use of opioids alone. In the current study, the authors examined the frequency and trend of concurrent opioid/BZD-S use and its associated risk factors among patients with cancer. METHODS: Data regarding the frequency and trend of concurrent opioid/BZD-S use were extracted for 1500 randomly selected patients referred to the outpatient palliative care clinic at The University of Texas MD Anderson Cancer Center between the calendar years of 2011 and 2016. To explore associated risk factors, the authors compared the demographic and clinical predictors of 418 patients each in the concurrent opioid/BZD-S group and opioids-only group. RESULTS: In 2011, at the time of referral to the palliative care clinic, 96 of 221 patients with cancer (43%) were prescribed concurrent opioids/BZD-S. This rate progressively declined to 67 of 217 patients (31%) by 2016 (P = .0008). Patients in the concurrent opioid/BZD-S group had a higher percentage of females (233 individuals; 55% [P = .007]) and whites (323 individuals; 77% [P = .002]), and patients reported higher scores regarding depression (P = .0001), anxiety (P ≤ .0001), drowsiness (P = .048), and worst feeling of well-being (P = .001). The morphine equivalent daily dose was significantly higher in concurrent opioid/BZD-S group (median of 67.5 mg/day [interquartile range (IQR), 30-135 mg/day] vs 60 mg/day [IQR, 30-105 mg/day]; P = .034). Multivariate analysis demonstrated that anxiety (P ≤ .0001), white race (P = .0092), and poor Eastern Cooperative Oncology Group performance status (P = .0017) were significantly associated with concurrent use. CONCLUSIONS: The concurrent use of opioids with BZD-S has declined but continues to be frequent among patients with cancer. Anxiety, white race, and poor Eastern Cooperative Oncology Group performance status were associated with its use. More research is needed to explore which medications can replace these agents.
