Caregivers of advanced cancer patients face challenges impacting their quality of life (QoL). While evidence suggests that family sense of coherence (FSOC) can enhance individual psychological well-being and reduce distress symptoms, the precise mechanism through which FSOC improves caregivers' QoL remains unclear. This study aimed to explore the relationships among FSOC, psychological resilience, psychological distress, and QoL in primary caregivers of advanced cancer patients. A cross-sectional observational study was undertaken from June 2020 to March 2021 across five tertiary hospitals in China. Instruments included a general characteristic questionnaire, the Family Sense of Coherence Scale, the Patient Health Questionnaire-4, the 10-item Connor–Davidson Resilience Scale, and the 8-item SF-8 health survey. Pearson's correlation and chain mediation analyses were performed using IBM SPSS (version 21) and PROCESS macro (version 3.4). Out of 290 valid questionnaires, results demonstrated that FSOC directly and positively influences caregivers' QoL. Psychological distress partially mediated the FSOC-QoL association, with paths "FSOC-psychological distress-QoL" and "FSOC-psychological resilience-psychological distress-QoL" contributing 43.08% and 6.72% of the total effect, respectively. Furthermore, this study distinguished physical and mental aspects of QoL, confirming both conform to the chain mediation model. FSOC impacts caregivers' QoL directly and indirectly through the mediation of psychological distress and the chain mediation effect of "psychological resilience-psychological distress". These insights enhance our understanding of the complex interplay between FSOC and QoL, underscoring the potential benefits of bolstering FSOC to strengthen caregiver resilience, alleviate distress, and ultimately elevate their QoL.

Objective: Glucose metabolism is impacted by circadian disruption. Dinner-bedtime interval (DBI) was an accessible indicator to reflect the alignment between dinner time and circadian clock. We aimed to investigate the association of DBI with type 2 diabetes mellitus (T2DM). Methods: 7676 adult subjects from the Henan Rural Cohort were included. Their demographic information including dinner time and bedtime was collected. Fasting venous blood samples were collected for biochemical determinations. Generalized linear regression model was used to analyze the factors influencing DBI. Furthermore, logistic regression incorporated with restricted cubic spline model was applied to evaluate the association between DBI and T2DM. Results: The results of multiple linear regression model showed that age (β: -0.018, 95% CI: -0.021, -0.015) was negatively correlated with DBI. Female (β: 0.311, 95% CI: 0.229, 0.393), junior high school education (β: 0.246, 95% CI: 0.187, 0.306), high school education or above (β: 0.346, 95% CI: 0.259, 0.433), average monthly income with 1000–1999 CNY(0.102, 95% CI: 0.032, 0.171), average monthly income ≥ 2000 CNY (β: 0.164, 95% CI: 0.076, 0.251), moderate physical activity (β: 0.134, 95% CI: 0.071, 0.197), current smokers (β: 0.214, 95% CI: 0.118, 0.309), current drinkers (β: 0.099, 95% CI: 0.008, 0.190) were positively correlated with DBI. Furthermore, DBI was significantly associated with T2DM (adjusted OR: 0.910, 95%CI: 0.845–0.979, P = 0.012). DBI longer than 3 h was associated with decreased risk of T2DM (adjusted OR: 0.773, 95%CI: 0.648–0.921, P = 0.004). Conclusions: DBI larger than 3 h is beneficial to T2DM prevention. Further investigation is required to verify the association. [ABSTRACT FROM AUTHOR]

Particulate matter (PM10) changes have been confirmed as one of the contributory factors affecting human health, the association between PM10 pollution and the hospitalization of chronic obstructive pulmonary disease (COPD) with comorbidity diseases was rarely reported. The same inpatient more than twice times admissions with COPD illness from January 1, 2016 to December 31, 2021 were identified from hospitals in the 17 cities of Henan, Central China. City-specific associations were firstly estimated using the case time series (CTS) model and then combined to obtain the regional average association. The multivariate meta-analytic model produces pooled estimates of the set of coefficients representing the PM10-COPD hospitalizations association across the 17 cities. Cause-specific hospitalization analyses were performed by COPD patients with different comorbidity combinations. A total of 34,348 elderly (age ≥ 65) subjects were analyzed and with a total of 35,122.35 person-years. These coefficients can be used to compute the linear exposure–response curve expressed as relative risk (RR) in per 10 µg/m3 increase in PM10 at lag03, which was 1.0091 (95% CI 1.0070–1.0112) for COPD with comorbidity, 1.0089 (95% CI 1.0067–1.0110) for COPD with circulatory system diseases, 1.0079 (95% CI 1.0052–1.0105) for COPD with respiratory system diseases, 1.0076 (95% CI 1.0032–1.0121) for COPD with endocrine system diseases, and 1.0087 (95% CI 1.0013–1.0162) for COPD with genitourinary system diseases, respectively. Some heterogeneity was found across cities, with estimates ranging from 1.0227 in the Puyang and Jiaozuo to 1.0053 in Henan Provance, China. The effect of higher PM10, on average, was higher in studies for northern cities, with a steeper raise in risk: per 10 µg/m3 increase in PM10, the RR from 1.0062 (95% CI 1.0030–1.0093) for the 10th percentile of latitude to 1.0124 (95% CI 1.0089–1.0160) for the 90th percentile. Our findings indicated that PM10 exposure may increase the risk of hospitalizations for COPD with comorbidity. Moreover, there might be a higher morbidity risk associated with PM10 in northern latitudes, indicating that stricter air quality standards could potentially reduce PM10-related morbidity among individuals with COPD. These findings have implications for the implementation of effective clean air interventions aligned with national climate policies. [ABSTRACT FROM AUTHOR]

To assess the level of supportive care needs of caregivers of colorectal cancer patients and explore the related key influencing factors. Totaling 283 caregivers of patients with colorectal cancer were investigated in this study. Firstly, caregivers were invited to complete a set of questionnaires, including the general information questionnaire, the Supportive Care Needs Survey-Partners and the Caregivers of cancer patients, the Caregiver Preparedness Scale, the Benefit Finding Scale, and the Comprehensive Score for Financial Toxicity. Univariate and multivariate linear regression were performed to investigate the associated factors of supportive care needs. The caregivers of patients with colorectal cancer have a moderate level of needs, scored at 2.71 ± 0.42. Caregiver preparedness, benefit finding, and financial toxicity were significantly negatively associated with the supportive care needs of caregivers (r = − 0.555, P < 0.001; r = − 0.534, P < 0.001; and r = − 0.615, P < 0.001, respectively). Our multivariate regression analysis identified some factors that directly affected the supportive care needs of caregivers, including the duration of illness, tumor stage, the age and educational level of caregivers, caregiver preparedness, benefit finding, and financial toxicity (R2 = 0.574, F = 23.337, P < 0.001). Supportive care needs are common among caregivers of colorectal cancer patients. Higher caregiver preparedness, benefit finding, and financial toxicity tend to ease these needs. Healthcare workers should have an in-depth understanding of the needs of caregivers of colorectal cancer patients and actively provide targeted financial/informational/technical/emotional support to promote nursing skills and reduce caregivers’ burdens.

Purpose: The status and associated factors of the health-related quality of life of non-small-cell lung cancer (NSCLC) patients under targeted anti-cancer therapy have not been investigated. Self-management and coping style have been proven to be closely related to patients' health-related quality of life. Based on these observations, this study was designed to firstly assess the status of health-related quality of life, and then explore the relationships among coping styles, self-management, and health-related quality of life of NSCLC patients with skin adverse drug reactions under targeted therapy.Methods: We performed a cross-sectional study including 536 NSCLC patients with skin adverse drug reactions under targeted therapy in cancer clinics of three hospitals in China between May 2020 and May 2021. Structured questionnaires, including the Functional Assessment of Cancer Therapy-Epidermal Growth Factor Receptor Inhibitor 18, Cancer Patient Self-management Evaluation Scale, and Medical Coping Modes Questionnaire, were used to collect data. Relationships among coping style, self-management, and health-related quality of life were identified by Pearson correlation analysis and a multiple linear regression algorithm.Results: The total score of health-related quality of life was 46 ± 12.84 in 536 NSCLC patients with skin adverse drug reactions undergoing targeted therapy. Health-related quality of life was positively correlated with self-management (r = 0.785, P < 0.01) and facing (r = 0.807, P < 0.01) and negatively correlated with yield (r =  - 0.718, P < 0.01), avoidance (r =  - 0.711, P < 0.01), and the severity of skin adverse reactions (r =  - 0.722, P = 0.000). Via multiple linear regression analysis, we identified some significant factors associated with health-related quality of life, including age, education level, combination of medicine, Charlson Comorbidity Index, stages of disease, facing, yield, symptom management, daily activity management, psychological and emotional management, self-efficacy, and self-management (P < 0.05).Conclusions: NSCLC patients with skin adverse drug reactions undergoing targeted therapy generally had a compromised health-related quality of life. The critical factors that were associated with the status of health-related quality of life were age, education level, comorbidity, the combinatorial application of drugs, stage of disease, self-management, and coping styles.

Purpose: The objectives are to explore the prevalence of DNR orders, the factors influencing them, and the association between DNR signing and health care utilization among advanced cancer patients.Methods: This was a retrospective cohort study. Data from cancer decedents in three hospitals in China from January 2016 to December 2017 during their last hospitalization before death were obtained from the electronic medical records system.Results: In total, 427 cancer patients were included; 59.0% had a DNR order. Patients who had solid tumors, lived in urban areas, had more than one comorbidity, and had more than five symptoms were more likely to have DNR orders. The cut-off of the timing of obtaining a DNR order was 3 days, as determined by the median number of days from the signing of a DNR order to patient death. Patients with early DNR orders (more than 3 days before death) were less likely to be transferred to the intensive care unit and undergo cardiopulmonary resuscitation, tracheal intubation, and ventilation, while they were more likely to be given morphine and psychological support compared with those with late (within 3 days before death) and no orders.Conclusions: Advanced cancer patients with solid tumors living in urban areas with more symptoms and comorbidities are relatively more likely to have DNR orders. Early DNR orders are associated with less aggressive procedures and more comfort measures. However, these orders are always signed late. Future studies are needed to better understand the timing of DNR orders. [ABSTRACT FROM AUTHOR]

Purpose: Several lines of clinical research support the efficacy of Cognitive behavioral therapy (CBT) with a large number of population and various disease conditions, however, the true effects of CBT interventions on Quality of Life of breast cancer patients remain unknown. The aim of the study was to evaluate the effect of Cognitive Behavioral Therapy on the Quality of Life of breast cancer patients. Methods: A systematic review of articles published using Web of Science (1950–January 2020); Medline via EBSCO (1992–January 2020); Science direct via ELSEVIER (1996–January 2020); SCOPUS (2004–January 2020); and PubMed (1946–January 2020 excluding Medline from 1992–January 2020) were included. Additional studies were included after checking reference lists of all relevant studies; searching ongoing trials and research registers and manual search. Data extraction was conducted by two independent authors and a third independent author checked the data extraction. The PRISMA statement was adopted. Result: Eleven Randomized controlled trials (RCT) with 1690 breast cancer patients were included in this review. The overall effect size of cognitive behavioral therapy on QoL of breast cancer patients was medium 0.39 (95% CI 0.12–0.66, P < 0.00001, I2 = 83%). Five studies had shown statistically significant improvement in functional and symptoms scales in the treatment group than the control group. Conclusion: CBT is effective in improving the Quality of Life of breast cancer patients. In future research, further randomized controlled trials with adequate randomization, allocation concealment, and appropriate blinding may be needed. [ABSTRACT FROM AUTHOR]

Fluvial erosion due to hydraulic force and bank failure under the influence of gravity are the two physical processes of riverbank erosion. This paper presents a new, simple, semi-analytical method to estimate the rate of fluvial erosion of non-cohesive riverbanks caused by hydraulic force. The derived equation is built based on the critical flow velocity concept, rather than the commonly used shear stress approaches. Because the distribution of the shear stress of a side wall varies considerably with the side wall's cross-sectional profile, it is difficult to estimate the shear stress distribution along a river bank. In contrast, the cross-sectional contours of flow velocity close to the side wall are parallel to the wall to some extent, which suggests that the flow velocity is more reliable and more easily measured in comparison to the shear stress. Large-scale laboratory experiments were conducted to evaluate the critical-velocity-based model. The calculated results agree well with the measured data. This semi-analytical approach is promising for estimating the fluvial bank erosion rate in the field. [ABSTRACT FROM AUTHOR]

Evaluation of bone marrow involvement (BMI) by conventional bone marrow biopsy (BMB) can generate false-negative results if marrow disease is focal. The sensitivity of 18F-2-fluoro-2-deoxy- d-glucose positron emission tomography/computed tomography (FDG-PET/CT) in assessing BMI in extranodal NK/T cell lymphoma (ENKL) has not been determined. We retrospectively collected clinical data from a series of 55 patients with newly diagnosed ENKL, who have received both FDG-PET/CT and BMB prior to treatment. BMB results were used as reference standard. Twelve patients (21.8 %) were considered positive lymphomatous infiltration by FDG-PET/CT (PET-CT/BM+), and five patients (9 %) were identified positive by BMB (BMB/BM+). There was a discordant result in seven patients who were PET-CT/BM+ but BMB/BM−. The sensitivity and specificity of FDG-PET/CT for identifying BMI were 100 and 86 %, respectively. Then, we analyzed the overall survival (OS) and progression-free survival (PFS) of patients who were PET-CT/BM+ and PET-CT/BM−. The median follow-up time was 16 months (range, 3 to 43 months). PET-CT/BM+ patients possessed worse 2-year OS than PET-CT/BM− patients (84.8 vs 67.9 %, P < 0.05). The estimated 2-year PFS for PET-CT/BM− and PET-CT/BM+ patients were 72.7 and 41.9 % ( P < 0.05), respectively. However, it was hard to conclude that patients who were PET-CT/BM+ had similar survivals to advanced-stage patients due to the low number of patients who were PET-CT/BM+. In conclusion, FDG-PET/CT can complementally detect positive BMI patients missed by BMB in ENKL. The utility of FDG-PET/CT for defining bone marrow status has important prognostic value.

The prognosis of extranodal nature killer (NK)/T cell lymphoma (ENKL) is dismal because of its aggressive course and multidrug resistance. Currently, for patients with relapsed/refractory ENKL, l-asparaginase-based regimens such as l-asparaginase, ifosfamide, methotrexate, etoposide, and dexamethasone (SMILE) or l-asparaginase, methotrexate, and dexamethasone (AspaMetDex) are recommended. We retrospectively investigated the efficacy and safety of gemcitabine, pegaspargase, cisplatin, and dexamethasone (DDGP) combination chemotherapy in the treatment of 17 relapsed/refractory ENKL patients. Clinical data from these patients were collected and analyzed. The primary end point was overall response rate (ORR). All patients were subjected to 2 to 6 cycles of DDGP chemotherapy, and the median number of cycles of DDGP regimen administrated was four. The ORR was 88.2 % (15/17), with nine patients (52.9 %) achieved complete response (CR) and six patients (35.3 %) achieved partial response (PR). The median follow-up time was 17 months (range 2-28 months). The 1-year overall survival (OS) rate and 1-year progression-free survival (PFS) were 82.4 and 64.7 %, respectively. For those CR responders, the median PFS was 17 months. Grade 3/4 neutropenia occurred in nine patients (52.9 %) and grade 3/4 thrombocytopenia occurred in six patients (35.3 %). DDGP combination chemotherapy produces favorable outcomes in relapsed/refractory ENKL, and more attention should be paid to treatment-related myelosuppression. Further prospective trials are expected to define the efficacy. [ABSTRACT FROM AUTHOR]

Background: Amifostine has been shown to be capable of minimizing radiotherapy-induced oral mucositis, but whether it protects small intestinal mucosae from high-dose methotrexate-induced damage is presently unknown. Aim: We aimed to evaluate the protective effect of amifostine against high-dose methotrexate-induced small intestinal mucositis and its mechanism. Methods: Ninety Kunming mice were randomly divided into five experimental groups: saline control; high-dose methotrexate (HDMTX) group: treated with a single high dose of methotrexate; calcium folinate (CF) group: treated with high-dose methotrexate followed with CF; Amifostine group: treated with amifostine, followed with high-dose methotrexate; and amifostine-CF group: treated with amifostine pre-high-dose methotrexate and followed by CF post-high-dose methotrexate. Mouse weight, villus height and crypt depth, stool consistency, white blood cell count, death and survival were recorded. Bax and Bcl-2 mRNA expression were quantified by semi-quantitative PCR. Results: Compared to the mice treated with HDMTX, CF, and amifostine, mice treated with Amifostine-CF group were heavier and had greater villus height, crypt depth, and normal white blood cell count and lower diarrhea rate and mortality than the HDMTX, CF and amifostine groups. There was a significant decrease in enterocyte apoptosis in amifostine-CF mice compared with the HDMTX and CF groups. Conclusions: The effect of amifostine plus CF was greater than amifostine or CF alone in preventing high-dose methotrexate-induced intestinal mucositis and improving intestinal recovery in mice.

The aim of this study was to observe the effect of the Prunella vulgaris L extract on the Jurkat human T lymphoma cell line. Jurkat cells were cultivated with different concentrations of the extract from Prunella vulgaris L. The MTT assay and flow cytometry were employed to determine the cells’ proliferation inhibition ratio and the apoptosis rates, respectively. Agarose gel electrophoresis was used to observe cellular DNA fragmentation, and western blotting was used to observe changes in Bcl-2 and Bax protein expression. The Prunella vulgaris L extract remarkably inhibited the proliferation of Jurkat cells. This inhibition exhibited dose dependence, with an IC50 of 20.23 ± 0.31 μg/mL. Agarose gel electrophoresis showed that the apoptosis strap became wider and brighter, and flow cytometry showed that the apoptosis rate increased in a concentration-dependent manner. Western blotting showed that Bcl-2 protein was down-regulated and Bax protein was up-regulated during apoptosis. The extract from Prunella vulgaris L induced apoptosis of Jurkat cells by down-regulating Bcl-2 protein and up-regulating Bax protein. These actions inhibited the growth of Jurkat cells.
