Coping and Perception of Prognosis in Patients With Indolent Non-Hodgkin's Lymphoma

BACKGROUND

Indolent non-Hodgkin's lymphomas (iNHL) are a heterogenous group of mostly incurable diseases with prolonged illness courses and prognostic uncertainty. Yet, studies evaluating coping and perception of prognosis are limited.

METHODS

We conducted a cross-sectional study of adults newly diagnosed with iNHL in the past 3 months at a single academic center. We assessed quality of life (QOL: Functional Assessment of Cancer Therapy-General), psychological symptoms (Hospital Anxiety and Depression Scale), coping (Brief-COPE), and perception of prognosis (Prognosis Awareness Impact Scale).

RESULTS

We enrolled 70.6% (48/68) of eligible patients. Patients had older age (mean = 66.9,sd = 10.5), were female (60.4%), predominantly identified as White (85.4%), and had at least received a college degree (75%). Chronic lymphocytic leukemia (39.6%) and follicular lymphoma (33.3%) were the most common diagnoses. Overall, 27.1% and 14.6% of patients reported clinically significant anxiety and PTSD symptoms, respectively. Patients highly utilized acceptance (56.2%), seeking emotional support (47.9%), and denial (47.9%) as coping strategies at diagnosis. While 66.7% of patients recalled their oncologist assessment of illness as incurable, only 35.4% reported that the illness is unlikely to be cured. Overall, 45.8% indicated that they were worried about prognosis and 31.2% reported perseverating on their prognosis. Higher emotional coping with prognosis was associated with fewer anxiety (B = -0.6, SE = 0.2, P < .001), depression (B = -0.3, SE = .1, P = .005), and PTSD (B = -1.3, SE = 0.4, P < .001) symptoms and better QOL (B = 1.7, SE = 0.4, P < .001).

DISCUSSION

Patients with iNHL report substantial psychological distress, a diversity of coping strategies, and complex cognitive understanding of their prognosis. Interventions, which address prognostic uncertainty and promote positive emotional coping with prognosis, may ameliorate psychological distress in this population.

CT-guided pretreatment biopsy diagnosis in patients with thymic epithelial tumours: diagnostic accuracy and risk of seeding

AIM

To investigate the diagnostic performance of computed tomography (CT)-guided percutaneous transthoracic needle biopsy (PTNB) for thymic epithelial tumours (TETs) and the complication rate after PTNB including seeding after PTNB.

MATERIALS AND METHODS

This retrospective study identified PTNBs for anterior mediastinal lesions between May 2007 and September 2021. The diagnostic performance for TETs and complications were investigated. The concordance of the histological grades of TETs between PTNB and surgery was evaluated. The factors associated with pleural seeding after PTNB were determined using Cox regression analysis.

RESULTS

Of 387 PTNBs, 235 PTNBs from 225 patients diagnosed as TETs (124 thymomas and 101 thymic carcinomas) and 150 PTNBs from 133 patients diagnosed as other than TETs were included. The sensitivity, specificity, and accuracy for TETs were 89.4% (210/235), 100% (210/210), and 93.5% (360/385), respectively, with an immediate complication rate of 4.4% (17/385). The concordance rate of the histological grades between PTNB and surgery was 73.3% (77/105) after excluding uncategorised types of thymomas. During follow-up after PTNB (median duration, 38.8 months; range, 0.3-164.6 months), no tract seeding was observed. Pleural seeding was observed in 26 patients. Thymic carcinoma (hazard ratio [HR], 5.94; 95% confidence interval [CI], 2.07-17.08; p=0.001) and incomplete resection (HR, 3.29; 95% CI, 1.20-9.02; p=0.02) were associated with pleural seeding, while the biopsy approach type (transpleural versus parasternal) was not associated (p=0.12).

CONCLUSIONS

Pretreatment biopsy for TETs was accurate and safe and may be considered for diagnosing TETs, particularly when the diagnosis is challenging and histological diagnosis is mandatory.

Communication About Chimeric Antigen Receptor T-Cell (CAR-T) Therapy

Chimeric Antigen Receptor T-cell (CAR-T) therapy has revolutionized the treatment of patients with hematologic malignancies, yet treatment may coincide with the potential for life-threatening toxicities. Currently, no studies have investigated how oncologists communicate with patients about CAR-T therapy or what patients and their caregivers want to know prior to consenting for CAR-T therapy. This study characterizes the content of oncologist communication with patients and caregivers about the risks and benefits of CAR-T therapy and explore the information preferences of patients and their caregivers about CAR-T therapy. We conducted a multimethod study of 20 patients with hematologic malignancies referred for CAR-T therapy at the Massachusetts General Hospital and 10 caregivers. We audio recorded the initial outpatient visit with the oncologist to review and sign consent for CAR-T therapy. We subsequently surveyed patients and caregivers about information gaps that remained after consent. We then interviewed patients and caregiver about their perceptions of oncologist communication and information preferences after the consent visit, 1 month, and 3 months post-CAR-T therapy treatment. Qualitative data analysis was conducted using the framework approach. Six major themes regarding communication about CAR-T therapy were identified: (1) oncologists create a narrative of power and innovation about CAR-T therapy, (2) oncologists set clear expectations regarding CAR-T therapy, (3) oncologists preferentially discuss positive treatment outcomes and less frequently address treatment failures or uncertainties, (4) oncologists couple their discussion about risks of CAR-T therapy with assurances about risk mitigation strategies, (5) oncologists engage in empathetic communication throughout the consent visit, (6) patients and caregivers vary in their preferences regarding communication about CAR-T therapy but largely favor a positive discourse during the consent visit and (7) patients who completed CAR-T therapy and their caregivers report significant knowledge gaps during and after treatment. Overall, patients and caregivers felt well informed about CAR T-therapy yet identified communication gaps regarding, advanced care planning, treatment failure and treatment toxicities. A predominantly positive discourse between patients, caregivers, and oncologists around CAR-T therapy leaves patients and caregivers with significant knowledge gaps about negative outcomes. Further research is needed to help oncologists communicate about treatment uncertainties and help patients and their caregivers prepare for negative outcomes of CAR-T therapy.

Coping in patients with hematologic malignancies undergoing hematopoietic cell transplantation

ABSTRACT

Patients undergoing hematopoietic cell transplantation (HCT) must cope with physical and psychological symptoms. Yet, studies examining pre-HCT coping are limited. We aimed to characterize pre-HCT coping, evaluate the association of coping with baseline quality of life (QOL) and psychological distress, and identify sociodemographic factors associated with pre-HCT coping. We conducted a cross-sectional analysis of baseline data from a multisite randomized supportive care intervention trial among patients with hematologic malignancies undergoing allogeneic or autologous HCT. We assessed patient-reported QOL, psychological distress, and coping within 72 hours of admission for HCT. We used the median split method to dichotomize coping and multivariate regression analyses to characterize the association of coping with psychological distress and QOL. Of patients awaiting HCT (n = 360; mean age, 55.4 years; 49.7% autologous), 43.5% were high users of approach-oriented coping, whereas 31.3% were high users of avoidant coping. Patients reported high use of emotional support (60.9%), acceptance (51.2%), self-blame (33%), and denial (31.3%). Older age (≥65 years) was associated with less frequent use of avoidant coping (odds ratio, 0.5; P = .01). Approach-oriented coping was associated with better pre-HCT QOL (Beta(B) = 6.7; P = .001), and lower depression (B = -1.1; P = .001) and anxiety (B = -0.9; P = .02) symptoms. Avoidant coping was associated with worse pre-HCT QOL (B = -13.3; P < .001) and symptoms of depression (B = 1.9; P < .001), anxiety (B = 3.1; P < .001), and posttraumatic stress disorder (B = 8.1; P < .001). Pre-HCT coping is strongly associated with psychological distress and QOL. These data support the need for interventions to address coping during HCT hospitalization. This clinical trial was registered at www.clinicaltrials.gov as #NCT03641378.

Blueberry Supplementation Effects on Neuronal and Pathological Biomarkers in Subjects at Risk for Alzheimer's Disease: A Pilot Study

Background

There is a need to develop non-invasive practical lifestyle interventions for preventing Alzheimer's disease (AD) in people at risk, such as those with mild cognitive impairment (MCI). Blueberry consumption has been associated with reduced risk of dementia in some epidemiologic studies and with improvements in cognition in healthy aging adults. Blood-based biomarkers have emerged at the forefront of AD therapeutics research spurred by the development of reliable ultra-sensitive "single-molecule array" assays with 100-1000-fold greater sensitivity over traditional platforms.

Objective

The purpose of this study was to examine the effect of blueberry supplementation in MCI on six blood biomarkers: amyloid-beta 40 (Aβ40), amyloid-beta 42 (Aβ42), phosphorylated Tau181 (ptau181), neurofilament light (NfL), Glial Fibrillary acidic protein (GFAP), and Brain-Derived Neurotrophic Factor (BDNF).

Methods

This was a 12-week, open-label, pilot trial of 10 participants with MCI (mean age 80.2 years + 5.16). Subjects consumed 36 grams per day of lyophilized blueberry powder in a split dose consumed with breakfast and dinner. Baseline and endpoint venous blood was analyzed using an ultrasensitive SIMOA assay. Our aim was to test if blueberry supplementation would particularly impact p-tau181, NfL, and GFAP elevations associated with the neurodegenerative process.

Results

There were no statistically significant (p < 0.05) changes from baseline to endpoint for any of the biomarker values or in the ratios of Aβ42 / Aβ40 and ptau181/ Aβ42. Adverse effects were mild and transient; supplementation was relatively well tolerated with all subjects completing the study.

Conclusion

To our knowledge, this is the first study to prospectively examine the effects of blueberry supplementation on a panel of blood biomarkers reflecting the neurodegenerative process. Our findings raise two possibilities - a potential stabilization of the neurodegenerative process or a lack of a direct and acute effect on beta-amyloid/tau/glial markers. A larger controlled study is warranted.

Characteristics and Outcomes of Recipients of Heart Transplant with Coronarvirus Disease 2019 Who Received Casirivimab Plus Imdevimab Infusion

Purpose

Heart transplant (HT) recipient are at increased risk of adverse outcomes following COVID-19 infection and may benefit from monoclonal antibody infusion to mitigate progression to clinically severe disease. The aim of this study is to describe the outcomes of HT patients who experienced mild to moderate coronavirus disease 2019 (COVID-19), with subsequent administration of casirivimab plus imdevimab administration.

Methods

A retrospective review of all HT recipients who were infected with COVID-19, and subsequently infused with monoclonal antibodies in a large academic medical center between January 1, 2021 to September 1, 2021.

Results

14 HT patients were included in the analysis. The median age was 57.5 (interquartile range [IQR], 41.5-64) years, 10 (71%) were men, and median time from HT was 3.48 (IQR, 1.00-11.82) years. Comorbid conditions included hypertension in 6 patients (43%), diabetes in 4 (29%), and chronic kidney disease in 6 (43%). Eight patients (57%) were previously vaccinated, predominantly with the Pfizer-BioNTech vaccine. Three participants (21%) were admitted after clinical progression of COVID-19. Among patients managed at the study institution, mycophenolate mofetil was discontinued in two patients (14%) and calcineurin inhibitor was maintained at previous levels in all fourteen patients (100%). Of the admitted patients, 1 was treated with high dose corticosteroids alone and 2 were treated with corticosteroids plus remdesivir. No patient required intubation. All 3 patients were discharged home and no patients in this cohort died.

Conclusion

In this single-center case series, HT patients with mild-moderate COVID-19 who were treated with monoclonal antibody infusion had a hospitalization rate of 21% and 100% survival. Further studies are required to optimize management of COVID-19 infection in the HT population.

Association of low skeletal muscle mass with the presence of advanced colorectal neoplasm: integrative analysis using three skeletal muscle mass indices

AIM

This study aimed to evaluate an association between colorectal neoplasm (CRN) and skeletal muscle mass using three widely accepted skeletal muscle mass indices (SMIs) in a large population at average risk.

METHOD

We performed a cross-sectional study using a screening colonoscopy database of 33 958 asymptomatic subjects aged 40-75 years. Appendicular skeletal muscle mass (ASM) was measured using a bioelectrical impedance analyser. ASM adjusted for height squared (ASM/ht² ), weight (ASM/wt) and body mass index (ASM/BMI) were used as indices for muscle mass. Logistic regression models were used to evaluate the association between SMIs and CRN.

RESULTS

In a multivariable-adjusted model, the risk of an advanced CRN increased linearly with decreasing quartiles for all three SMIs. The adjusted odds ratios (ORs) for advanced CRN in quartiles 1, 2 and 3 of ASM/wt compared with that in quartile 4 were 1.279, 1.196 and 1.179, respectively (P_trend  = 0.017); for ASM/BMI, ORs were 1.307, 1.144 and 1.091, respectively (P_trend  = 0.002); and for ASM/ht² , ORs were 1.342, 1.169 and 1.062, respectively (P_trend  = 0.002). The risk of distally located advanced CRN was higher in quartile 1 than in quartile 4 for all three SMIs (ASM/wt, OR = 1.356; ASM/BMI, OR = 1.383; ASM/ht² , OR = 1.430).

CONCLUSION

Our study demonstrated that low skeletal muscle mass was consistently associated with the presence of advanced CRN in a population at average risk regardless of the operational definition of the SMI, and it was particularly associated with distal advanced CRN.

Survival Benefit of Early Cancer Detection Through Regular Endoscopic Screening for De Novo Gastric and Colorectal Cancers in Korean Liver Transplant Recipients

BACKGROUND

De novo malignancy is not uncommon after liver transplantation (LT). Gastric cancer is one of the most common malignancies in both the Korean general population and LT recipients, and colorectal cancer prevalence is gradually increasing.

METHODS

Among 3690 adult recipients who underwent LT from January 1999 and December 2013, the screening patterns and prognosis of 26 cases of gastric cancer and 22 cases of colorectal cancer were analyzed.

RESULTS

For gastric cancer, the mean patient age was 54.6 ± 6.2 years at LT and 59.5 ± 6.7 years at cancer diagnosis, with a post-transplant interval of 60.2 ± 29.8 months. Patients were divided into regular (n = 18) and non-regular (n = 8) screening groups, with early cancer found in 14 and 0 patients; their 2-year survival rates after cancer diagnosis were 93.1% and 33.3% (P = .006), respectively. Endoscopic resection was successfully performed in 8 patients, all in the regular screening group. For colorectal cancer, the mean patient age was 53.3 ± 6.1 years at LT and 58.1 ± 6.7 years at cancer diagnosis, with a post-transplant interval of 54.3 ± 38.0 months. Patients were divided into regular (n = 19) and non-regular (n = 3) screening groups, with early cancer found in 12 and 0 patients; their 2-year survival rates after cancer diagnosis of 92.3% and 33.3% (P = .003), respectively. Endoscopic resection was successfully performed in 6 patients, all in the regular screening group.

CONCLUSIONS

LT recipients are strongly advised to undergo regular screening studies for various de novo malignancies, especially cancers common in the general population. Regular endoscopic screening contributes to the timely detection of gastric and colorectal cancers, improving post-treatment survival outcomes.

Heat-killed Lactobacillus spp. cells enhance survivals of Caenorhabditis elegans against Salmonella and Yersinia infections

This study examined the effect of feeding heat-killed Lactobacillus cells on the survival of Caenorhabditis elegans nematodes after Salmonella Typhimurium and Yersinia enterocolitica infection. The feeding of heat-killed Lactobacillus plantarum 133 (LP133) and Lactobacillus fermentum 21 (LP21) cells to nematodes was shown to significantly increase the survival rate as well as stimulate the expression of pmk-1 gene that key factor for C. elegans immunity upon infection compared with control nematodes that were only fed Escherichia coli OP50 (OP50) cells. These results suggest that heat-killed LP133 and LF21 cells exert preventive or protective effects against the Gram-negative bacteria Salm. Typhimurium and Y. enterocolitica. To better understand the mechanisms underlying the LF21-mediated and LP133-mediated protection against bacterial infection in nematodes, transcriptional profiling was performed for each experimental group. These experiments showed that genes related to energy generation and ageing, regulators of insulin/IGF-1-like signalling, DAF genes, oxidation and reduction processes, the defence response and/or the innate immune response, and neurological processes were upregulated in nematodes that had been fed heat-killed Lactobacillus cells compared with nematodes that had been fed E. coli cells.

SIGNIFICANCE AND IMPACT OF THE STUDY

In this study, the feeding of heat-killed Lactobacillus bacteria to Caenorhabditis elegans nematodes was shown to decrease infection by Gram-negative bacteria and increase the host lifespan. C. elegans has a small, well-organized genome and is an excellent in vivo model organism; thus, these results will potentially shed light on important Lactobacillus-host interactions.

Higher serum uric acid as a protective factor against incident osteoporotic fractures in Korean men: a longitudinal study using the National Claim Registry

In this large longitudinal study of 16,078 Korean men aged 50 years or older, we observed that baseline elevation of serum uric acid level significantly associated with a lower risk of incident fractures at osteoporosis-related sites during an average follow-up period of 3 years.

INTRODUCTION

Male osteoporosis and related fractures are becoming recognized as important public health concerns. Oxidative stress has detrimental effects on bone metabolism, and serum uric acid (UA) is known to be a strong endogenous antioxidant. In the present study, we performed a large longitudinal study with an average follow-up period of 3 years to clarify the role of UA on the risk of incident osteoporotic fractures (OFs).

METHODS

A total of 16,078 Korean men aged 50 years or older who had undergone comprehensive routine health examinations were enrolled. Incident fractures at osteoporosis-related sites (e.g., hip, spine, distal radius, and proximal humerus) that occurred after the baseline examinations were identified from the nationwide claims database of the Health Insurance Review and Assessment Service of Korea by using selected International Classification of Diseases, 10th revision codes.

RESULTS

In total, 158 (1.0 %) men developed incident OFs. The event rate was 33.1 per 10,000 person-years. Subjects without incident OFs had 6.0 % higher serum UA levels than subjects with OFs (P = 0.001). Multivariable-adjusted Cox proportional hazard analyses adjusted for age, body mass index, glomerular filtration rate, lifestyle factors, medical and drug histories, and the presence of baseline radiological vertebral fractures revealed that the hazard ratio per standard deviation increase of baseline UA levels for the development of incident OFs was 0.829 (95 % CI = 0.695-0.989, P = 0.038).

CONCLUSIONS

These data provide the epidemiological evidence that serum UA may act as a protective factor against the development of incident OFs in Korean men.

Helical tomotherapy versus conventional radiation to deliver abdominopelvic radiation

While whole abdominopelvic radiation (APRT) provided satisfactory radiation dosimetry for the treatment of cancers with peritoneal dissemination, APRT was abandoned due to unsatisfactory tumor control from necessary radiation shielding of vital organs. Our goal was to develop a helical tomotherapy (TOMO) abdominopelvic radiation technique improving target tissue coverage while dose-limiting vital organs, especially hematopoietic bone marrow. This study reports our clinical development of a TOMO abdominopelvic radiation technique for treatment of patients with advanced stage ovarian cancer. Novel chemoradiosensitizing agent clinical trials incorporating our TOMO abdominopelvic radiation technique for treatment of patients with recurrent ovarian cancer are under development.

Association of restrictive ventilatory dysfunction with insulin resistance and type 2 diabetes in koreans

AIMS

To investigate associations of obstructive and restrictive patterns of ventilatory dysfunction with insulin resistance and type 2 diabetes mellitus (DM) in Koreans.

METHODS

We cross-sectionally examined clinical, laboratory, and pulmonary function data on 35,456 Korean adults (age 18-93 years, 40% women) recorded during regular health check-ups. Insulin resistance (IR) was determined from fasting serum insulin concentration and homeostasis model assessment (HOMA).

RESULTS

Individuals with type 2 DM and those with pre-diabetes (impaired fasting glucose levels) showed a higher prevalence of both restrictive (18% and 11%, respectively, VS. 8%; P<0.01) and obstructive (4.3% and 3.2%, respectively, VS. 2.3%; P<0.01) ventilatory dysfunction than did individuals with normal fasting glucose levels. Compared to subjects with normal ventilatory function, those with restrictive or obstructive ventilatory dysfunction were older, had higher systolic and diastolic blood pressure, and had elevated glucose and HbA1c levels. However, serum triglyceride, fasting insulin, and HOMA-IR were higher only in subjects with restrictive ventilatory dysfunction, and not in those with obstructive ventilatory dysfunction. On logistic regression analysis, the age and gender-adjusted odds ratio (OR) of restrictive ventilatory dysfunction for type 2 DM was 1.59 (95% confidence interval, 1.43-1.78). The increased OR remained significant after controlling for exercise, drinking, and smoking habits, presence of hypertension, body mass index, and waist circumference (OR=1.38 [1.23-1.55]). However, further adjustment for HOMA-IR attenuated the OR (1.11 [0.97-1.26]), making the OR statistically insignificant. In contrast, obstructive ventilatory dysfunction was not independently related to type 2 DM status.

CONCLUSION

Restrictive ventilatory dysfunction is independently associated with type 2 DM, probably VIA insulin resistance.
