RESUMO

PURPOSE: To determine whether socioeconomic disparities have an impact on the likelihood of suicide among prostate cancer patients. METHODS: Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) database for patients diagnosed with malignant prostate cancer between 2005 and 2020. The socioeconomic disparities of the patients were evaluated by median household income (MHI) and ethnicity. Ethnicity included Spanish-Hispanic-Latino and non-Spanish-Hispanic-Latino. A Cox proportional risk model was utilized. Using the Kaplan-Meier approach, the cumulative incidence of suicide mortality was measured. RESULTS: A total of 857,418 US population with prostate cancer were included. In the multivariate analysis, individuals with MHI over $75,000 had a lower risk of suicide mortality than those with MHI between $54,999 and $74,999 in all patients (aHRs: 0.693, 95 CI%: 0.603-0.797). Spanish-Hispanic-Latino displayed lower overall suicide mortality in all patients (aHRs: 0.426, 95% CI: 0.323-0.561). In the subgroup analysis of different ages, individuals with MHI over $75,000 had a lower risk of suicide than those with MHI between $54,999 and $74,999 in patients 60 to 79 years (aHRs: 0.668, 95% CI: 0.562-0.794) and individuals with MHI below $54,999 had higher suicide risk than those with MHI between $54,999 and $74,999 in patients 80+ years (aHRs: 1.786, 95% CI: 1.100-2.902). Hispanic-Latino individuals had lower overall suicide mortality in 00 to 59 years (aHRs: 0.420, 95% CI: 0.240-0.734), 60 to 79 years (aHRs: 0.445, 95% CI: 0.319-0.621), 80+ years (aHRs: 0.363, 95% CI: 0.133-0.988). CONCLUSION: Socioeconomic disparities, including MHI and ethnicity, are important factors strongly related to suicide risk in prostate cancer patients. The lower MHI individuals and non-Spanish-Hispanic-Latino individuals were associated with higher suicide risk.

RESUMO

Environmental air pollutants (black carbon (BC), nitrogen oxides (NOx), particulate matter with diameter < 2.5 µm (PM2.5), nitrogen dioxide (NO2), particulate matter with diameter <10 µm (PM10), and ozone (O3)) are one of the major menaces to mankind's health globally. This analysis reviews the association between exposure to these air pollutants and the chance of developing brain tumors in adults (total brain tumors, malignant brain tumors, and benign brain tumors). Studies published by April 2022 were searched. Raw effect sizes were converted to standardized effect sizes per 10 µg/m3 increase. Random effect models were applied to calculate combined effect size and 95% confidence intervals (CIs) were computed. A total of 8 articles were included for meta-analysis. The pooled effect size (ES) for per 10 µg/m3 BC intake was 1.67 (95% CI: 1.25, 2.22), P = 0.449. For every 10 µg/m3 rise in NO2 concentration, ES was 1.03 (95% CI: 1.01, 1.05), P = 0.319. Meanwhile, there was a boundary association between NOx and adult brain tumors (ES and 95% CI: 1.01; 1.00, 1.01/10 µg/m3; P = 0.716). While there was no conjunction between PM2.5, PM10, O3 (PM2.5: ES and 95% CI: 1.04; 0.99, 1.08/10 µg/m3; P = 0.834; PM10: ES and 95% CI: 1.01; 0.97, 1.04/10 µg/m3; P = 0.627; O3: ES and 95% CI: 0.97; 0.94, 1.00/10 µg/m3; P = 0.253). This research shows testimony of a significant link between air pollutants and brain tumors in adults, especially when exposed to BC, NO2, and NOx. This evidence emphasizes the importance of improving air quality as part of a comprehensive approach to prevent the occurrence and deterioration of brain tumors.

RESUMO

BACKGROUND: Colorectal cancer (CRC) is widely acknowledged as a prevalent malignancy and the second most common cause of cancer-related mortality worldwide. The aim of this study was to examine the independent impact of Median Household Income (MHI) on prognosis and survival outcomes in patients with CRC. METHODS: Data from 17 cancer registries of the United States Surveillance, Epidemiology, and End Results program, with follow-up extended until November 2022 was analyzed. A Cox proportional hazards regression analysis was conducted to evaluate the influence of different levels of MHI on survival outcomes among patients with CRC. A total of 761,697 CRC patient records were retrieved from the SEER database. RESULTS: The Cox regression analysis results indicated that patients with higher MHI exhibited improved overall survival outcomes when compared to those with lower MHI (MMHI: P < 0.001; HMHI: P < 0.001). Regardless of the specific tumor location, gender, stage of CRC, or treatment method, higher MHI is consistently linked to improved survival outcomes. However, this association was not found to be statistically significant among American Indian/Alaska Native (MMHI: P = 0.017; HMHI: P = 0.081), Asian or Pacific Islander (MMHI: P = 0.223; HMHI: P = 0.002) and unmarried or domestic partner patients (MMHI: P = 0.311; HMHI: P = 0.011). CONCLUSION: These results emphasize the importance of considering socioeconomic factors, such as income level, in understanding and addressing disparities in survival outcomes of CRC patients.

RESUMO

AIMS AND OBJECTIVES: To determine the global prevalence of nursing burnout syndrome and time trends for the last 10 years. BACKGROUND: The prevalence of burnout syndrome varied greatly in different regions in the last 10 years, so the average prevalence and time trends of nursing burnout syndrome for the last 10 years were not completely clear. DESIGN: A meta-analysis conducted in the PRISMA guidelines. METHODS: CINAHL, Web of Science, and PubMed were searched for trials on the prevalence of nursing burnout syndrome from 2012 to 2022 systematically. Hoy's quality assessment tool was used to evaluate the risk of bias. The global prevalence of nursing burnout syndrome was estimated, and subgroup analysis was used to explore what caused heterogeneity. Time trends for the last 10 years were evaluated by meta-regression using Stata 11.0. RESULTS: Ninety-four studies reporting the prevalence of nursing burnout were included. The global prevalence of nursing burnout was 30.0% [95% CI: 26.0%-34.0%]. Subgroup analysis indicated that the specialty (p < .001) and the region (p < .001) and the year (p < .001) were sources of the high heterogeneity. Meta-regression indicated that it tended to increase gradually for the last 10 years (t = 3.71, p = .006). The trends increased in Europe (t = 4.23, p = .006), Africa (t = 3.75, p = .006) and obstetrics (t = 3.66, p = .015). However, no statistical significance was found in ICU (t = -.14, p = .893), oncology (t = -0.44, p = .691) and emergency department (t = -0.30, p = .783). CONCLUSIONS: A significant number of nurses were found to have moderate-high levels of burnout syndrome for the last 10 years. The meta-analysis also indicated an increased trend over time. Therefore, more attention to the prevalence of nursing burnout syndrome is urgently required. RELEVANCE TO CLINICAL PRACTICE: High prevalence of nursing burnout may attract more attention from the public. This analysis may serve as an impetus for relevant policy to change nurses' working conditions and reduce the occurrence of burnout.

RESUMO

Aim: To develop a Cancer Patient Suicidal Ideation Scale (CAPASIS) and test its reliability and validity. Patients & methods: An initial CAPASIS was developed. Clinical assessment was conducted using an adjusted initial scale with 239 cancer patients for item reduction and 253 for scale validation. Results: Item selection analyses resulted in 22 items. The revised model fits were acceptable (normal chi-square [χ2/df] = 1.919; standardized root mean residual  = 0.057; root mean square error of approximation = 0.060; goodness fit index = 0.882; adjusted goodness fit index [AGFI] = 0.844; Tucker-Lewis index = 0.898; comparative fit index  = 0.915; incremental fit index  = 0.917). The Cronbach's alpha coefficient was 0.911. Conclusion: The CAPASIS has good validity and reliability, with a six-factor structure of 'entrapment', 'defeat', 'isolation', 'hopelessness', 'burdensomeness' and 'humiliation', which can help identify patients with suicidal ideation.

RESUMO

BACKGROUND: During the COVID-19 epidemic, palliative care has become even more indispensable for cancer patients. AIM: To identify the changes in palliative care for cancer patients and improvements in palliative care quality during the COVID-19 pandemic. DESIGN: A systematic review and narrative synthesis was conducted in PubMed, Embase and Web of Science. An evaluation tool using mixed methods was used to assess the quality of the study. The main relevant themes identified were used to group qualitative and quantitative findings. RESULTS: A total of 36 studies were identified, primarily from different countries, with a total of 14,427 patients, 238 caregivers and 354 health care providers. Cancer palliative care has been experiencing several difficulties following the COVID-19 pandemic, including increased mortality and infection rates as well as delays in patient treatment that have resulted in poorer prognoses. Treatment providers are seeking solutions such as electronic management of patients and integration of resources to care for the mental health of patients and staff. Telemedicine plays an important role in many ways but cannot completely replace traditional treatment. Clinicians strive to meet patients' palliative care needs during special times and improve their quality of life. CONCLUSIONS: Palliative care faces unique challenges during the COVID-19 epidemic. With adequate support to alleviate care-related challenges, patients in the home versus hospital setting will be able to receive better palliative care. In addition, this review highlights the importance of multiparty collaboration to achieve personal and societal benefits of palliative care. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

RESUMO

PURPOSE: To explore the high-risk period of the occupation of suicide after diagnosis; and clarify the risk factors of suicidal behaviors (suicidal ideation, suicide attempt, and suicidal death) behind the lung cancer patients during the cancer cure process. METHODS: This scoping review was conducted through the whole month of April 2021. We extracted data of the suicide mortality after diagnosis and latent risk factors of suicidal behaviors among lung cancer patients where we used to study from the two online databases which are PubMed and Web of Science. Two online databases were searched and written in English without age restriction. To note that the standardized mortality ratio (SMR), person-years, and odds ratio (OR) associated with lung cancer were documented. RESULTS: Out of 570 records, 23 studies mentioned suicidal behaviors and lung cancer met the included criteria. Eleven (n = 47.8%) of the selected publications reported changes in suicide mortality. None of them reported suicidal ideation or suicide attempt after diagnosis. The individuals with lung cancer have significantly higher rates of suicidal death (SMR, 2.04-13.4) during the first years after diagnosis and decrease over subsequent years (SMR, 0.66-3.17). The median time from cancer diagnosis to suicide death was around 7 months. Across all studies with the 22 studies that examined factors, we extracted the data of the suicidal ideation (n = 3), suicide attempt (n = 1), and suicidal death (n = 18) in individuals. For patients with suicidal ideation, there was a significantly higher incidence in males than in females. Among patients who attempted suicide, the incidence of mental illness is greater than the incidence of physical illness. Factors for suicidal death, including gender (male, 56.3-100%), prognosis tumors (poor, 25.8-66.3%), marital status (widowhood or unmarried, 19-75.7%), and age of patients (> 70 years, 24.5-47%) with lung cancer, play a vital role. Treatment of lung cancer is expected to affect a patient in his/her mental state. CONCLUSION: Overall, our finding indicates that lung cancer patients have been presented with a higher incidence of suicide death in a specific period, especially the early years after diagnosis. Discovering risk factors for suicide helps prevent potential suicide. It is essential to screen lung cancer patients for suicidal ideation, especially those with high-risk factors. Future prospective studies are necessary to confirm these findings to support care.

RESUMO

Parkinson's disease (PD) is pathologically characterized by selective loss of dopaminergic neurons in the midbrain and the existence of intracellular protein inclusions termed Lewy bodies, largely composed of α-synuclein. Genetic studies have revealed that rare point mutations in the gene encoding α-synuclein including A30P, A53T, and E46K are associated with familial forms of PD, indicating a pathological role for mutant α-synuclein in PD etiology. However, the mechanisms underlying the neuronal toxicity of mutant α-synuclein are still to be elucidated. Growing evidence has suggested a deleterious effect of mutant α-synuclein on the autophagy-lysosome pathway. In this study, we discovered that overexpression of human E46K mutant α-synuclein impaired macroautophagy in mammalian cells. Our data showed that overexpression of E46K mutant α-synuclein impaired autophagy at an early stage of autophagosome formation via the c-Jun N-terminal kinase 1 (JNK1)-Bcl-2 but not the mammalian target of rapamycin (mTOR) pathway. Overexpressed E46K mutant α-synuclein inhibited JNK1 activation, leading to a reduced Bcl-2 phosphorylation and increased association between Bcl-2 and Beclin1, further disrupting the formation of Beclin1/hVps34 complex, which is essential for autophagy initiation. Furthermore, overexpression of E46K mutant α-synuclein increased the vulnerability of differentiated PC12 cells to rotenone treatment, which would be partly due to its inhibitory effects on autophagy. Our findings may shed light on the potential roles of mutant α-synuclein in the pathogenesis of PD.

RESUMO

Six novel iridal-type triterpenoids with a previously unreported 3,6-dihydro-2H-pyran moiety, named spirioiridotectals A-F (1-6), were isolated from the ethanol extract of the rhizomes of Iris tectorum. Their structures were elucidated on the basis of extensive spectroscopic analysis. Furthermore, in in vitro bioactivity assays, compounds 1, 2, and 6 exhibited neuroprotective activities against serum-deprivation-induced PC12 cell damage.
