Frailty and all-cause and cancer-related mortality in cancer patients: A prospective cohort study.

PURPOSE: To evaluate the associations between frailty and all-cause and cancer-related mortality. Additionally, the objective is to compare the magnitude of these associations between older adults and younger adults. METHODS: We gathered baseline data from NHANES (1999-2018) and developed a cumulative index consisting of 39 items to evaluate frailty. The National Death Index database was utilized to track the survival status of individuals. The Cox regression model was employed to estimate the associations between frailty status and all-cause and cancer-related mortality. RESULTS: Ultimately, 3398 cancer patients were included in the analysis, comprising 910 younger adults and 2488 older adults. Compared to non-frail patients, the elevated all-cause and cancer-related mortality among pre-frail patients was not statistically significant (HRs = 1.312, 95%CI: 0.956-1.800, P = 0.092; HRs = 1.462, 0.811-2.635, P = 0.207). However, a significant elevation of both all-cause and cancer-related mortality risk was observed among frail patients (HRs = 2.213, 1.617-3.030, P < 0.001; HRs = 2.463, 95%CI = 1.370-4.429, P = 0.003). Frailty individuals demonstrated a more pronounced association with the prediction of all-cause mortality in younger (HRs = 2.230, 1.073-4.634, P = 0.032) than in older adults (HRs = 2.090, 1.475-2.960, P < 0.001). Sensitivity analysis consistently revealed robust results. RCS plots suggested a progressively escalating dose-response correlation between frailty and both all-cause and cancer-related mortality risk. CONCLUSIONS: Pre-frailty did not result in an increase in mortality risks compared to non-frailty. However, frailty caused a higher all-cause and cancer-related mortality risk than non-frailty. Identifying those at risk and implementing targeted interventions may contribute to extending healthy life expectancy, regardless of age.

Body mass index and pressure injuries risk in hospitalized adult patients: A dose-response analysis.

BACKGROUND: The association between underweight and pressure injuries (PIs) has been established in several studies. However, there is a lack of well-designed research investigating the connection between overweight and obesity with these injuries. OBJECTIVE: This meta-analysis aims to investigate the dose-response relationship between body mass index (BMI) and the risk of PIs in adult hospitalized patients. METHODS: PubMed, Web of Science, and MEDLINE Databases were searched from inception to May 2024. Observational articles with at least three BMI categories were included in the study. BMI was defined as underweight, normal weight, overweight, and morbid obesity for the meta-analysis. The non-linear relationship between BMI and the risk of PIs in hospitalized adults was investigated using restricted cubic spline models. Fractional polynomial modeling was used. RESULTS: Eleven articles reporting at least 3 categories of BMI met the inclusion criteria, including 31,389 participants. Compared to patients with normal weight, those with underweight, obesity, and morbid obesity exhibited an increased risk of PIs, with odds ratios of 1.70 (95%CI:1.50-1.91), 1.12 (95%CI:1.02-1.24), 1.70 (95%CI:1.13-2.55), respectively. A J-shaped dose-response model was established for the relationship between PI risk and BMI (Pnon-linearity < 0.001, Plinearity = 0.745). CONCLUSION: The J-shaped dose-response pattern revealed that underweight, obesity and morbid obesity heightened the risk of PIs in hospitalized adults. Lower and higher BMI values may signify an increased risk for PIs, particularly among the elderly with lower BMI, providing valuable guidance for medical staff.

Prevalence of anxiety, depression, sleeping problems, cognitive impairment, and suicidal ideation in people with autoimmune skin diseases.

BACKGROUND: Autoimmune skin diseases (ASDs) such as psoriasis and vitiligo, in addition to causing visible skin symptoms, are closely associated with psychological health issues. However, a comprehensive understanding of the prevalence of these psychological comorbidities in affected individuals is lacking. This study aims to identify the prevalence of anxiety, depression, sleeping problems, cognitive impairment, and suicidal ideation in people with ASDs. METHOD: PubMed, MEDLINE, Web of Science, and Cochrane Library searches were conducted from 1993 to May 2024. Observational studies reporting prevalence data for anxiety, depression, sleeping problems, cognitive impairment, and suicidal ideation among people with ASDs were included in the analysis. The Newcastle-Ottawa scale was used to evaluate the quality of studies. RESULTS: The study included 114 studies from 37 countries including 823,975 participants. The estimated pooled prevalence of anxiety in patients with ASDs was 33.3% (95% CI: 27.3-29.3%). The estimated pooled prevalence of depression was 33.7% (95% CI: 29.2-38.1%). The estimated pooled prevalence of sleeping problems was 45.0% (95% CI:31.6-58.4%). The estimated pooled prevalence of cognitive impairment and suicidal ideation was 30.8% (95% CI:15.0-46.7%) and 21.6% (95% CI:13.4-29.8%), respectively. The most common mental disorder in patients with systemic lupus erythematosus and psoriasis was sleeping problems at 55.9% (95% CI: 35.6-76.1%, I2 = 97%) and 39.0% (95% CI: 21.1-56.9%, I2 = 99%). CONCLUSION: Among patients with ASDs, anxiety, depression, sleeping problems, cognitive impairment, and suicidal ideation were common. The most prevalent mental disorder among patients with systemic lupus erythematosus and psoriasis was sleeping problems. Those with ASDs may experience considerable psychological burdens, and integrated mental health support is necessary for their treatment.

Effect of Tranexamic Acid on Hidden Blood Loss in Percutaneous Endoscopic Transforaminal Lumbar Interbody Fusion: A Retrospective Study.

Purpose: Percutaneous endoscopic transforaminal lumbar interbody fusion (PE-TLIF) has become one of the most popular minimally invasive surgeries today. However, the issue of hidden blood loss (HBL) in this surgery has received little attention. This study aims to examine the HBL in PE-TLIF surgery and the effect of tranexamic acid (TXA) on blood loss. Methods: In our research, We conducted a retrospective analysis of 300 patients who underwent PE-TLIF from September 2019 to August 2023. They were divided into 2 groups based on whether they received intravenous TXA injection before surgery. The variables compared included: demographic data, pre-and postoperative hemoglobin (HB), hematocrit (HCT), platelets (PLT), red blood cells (RBC), total blood loss (TBL), visible blood loss (VBL), HBL, operation time, postoperative hospital stay, inflammatory markers, coagulation parameters, and adverse events. Results: Regarding demographic characteristics, besides the operation time, no significant differences were observed between the two groups. Compared with the control group, the TXA group showed a significant reduction trend in TBL, HBL, and VBL (P < 0.05). On the first day after surgery, there were significant differences in prothrombin (PT), activated partial thromboplastin time (APTT), and D-dimer (D-D) levels between the two groups. Similarly, HCT also found similar results on the third day after surgery. No adverse events occurred in either group. Conclusion: Research has found that there is a significant amount of HBL in patients undergoing PE-TLIF. Intravenous injection of TXA can safely and effectively reduce perioperative HBL and VBL. Additionally, compared to the control group, the TXA group shows a significant reduction in operation time.

Reduction of selenite to selenium nanoparticles by highly selenite-tolerant bacteria isolated from seleniferous soil.

The microbial reduction of selenite to elemental selenium nanoparticles (SeNPs) is thought to be an effective detoxification process of selenite for many bacteria. In this study, Metasolibacillus sp. ES129 and Oceanobacillus sp. ES111 with high selenite reduction efficiency or tolerance were selected for systematic and comparative studies on their performance in selenite removal and valuable SeNPs recovery. The kinetic monitoring of selenite reduction showed that the highest transformation efficiency of selenite to SeNPs was achieved at a concentration of 4.24 mM for ES129 and 4.88 mM for ES111. Ultramicroscopic analysis suggested that the SeNPs produced by ES111 and ES129 had been formed in cytoplasm and subsequently released to extracellular space through cell lysis process. Furthermore, the transcriptome analysis indicated that the expression of genes involved in bacillithiol biosynthesis, selenocompound metabolism and proline metabolism were significantly up-regulated during selenite reduction, suggesting that the transformation of selenite to Se0 may involve multiple pathways. Besides, the up-regulation of genes associated with nucleotide excision repair and antioxidation-related enzymes may enhance the tolerance of bacteria to selenite. Generally, the exploration of selenite reduction and tolerance mechanisms of the highly selenite-tolerant bacteria is of great significance for the effective utilization of microorganisms for environmental remediation.

Efficacy of recombinant human epidermal growth factor in pressure injury healing: evidence from Chinese randomized controlled trials.

OBJECTIVE: To evaluate the efficacy of recombinant human epidermal growth factor (rhEGF) in healing pressure injuries (PIs). METHODS: A meta-analysis was conducted of randomized controlled trials (RCTs) involving rhEGF in the treatment of PIs that were identified in PubMed, Web of Science, the Cochrane Library, and China National Knowledge Infrastructure (CNKI). The population, intervention, comparison, outcomes, study design (PICOS) strategy was applied to determine analysis eligibility. The Cochrane risk of bias tool was used, and statistical analysis, including sensitivity analysis, was performed of 3 outcomes indicators: the primary outcome was total efficacy of rhEGF in treating PIs, and the secondary outcomes were the proportion of complete healing and the time to complete healing. Total efficacy refers to the proportion of cases that have been cured, obviously effective, or effective. Complete healing refers to cases where the wound has healed, scabbed, and the scab has sloughed off. RESULTS: Sixteen RCTs were included, comprising a total of 1,206 patients. Study and control group size varied by outcomes. The total effective healing rate in rhEGF group was 97.18%, which was significantly higher than 83.38% in control group (OR: 5.69, [95% CI: 3.61, 8.97], z=7.49, P < .001). The proportion of complete healing in the rhEGF group was 73.30%, which was higher than 39.52% in control group (OR: 3.88, [95% CI: 3.01, 5.01], z=10.39, P < .001). Furthermore, the healing time using rhEGF was shorter (SMD: -2.14 days, [95% CI: -2.60, -1.67], z=9.07, P < .001). Sensitivity analyses indicated that the results were robust. CONCLUSIONS: The meta-analysis indicated that rhEGF was effective in healing PIs with few negative effects. Further research beyond Chinese populations involving larger studies and studies that distinguish between results found in using rhEGF alone or in combination are recommended.

Combined with the first dorsal (plantar) metatarsal artery pedicle free bilobed flap with a cell scaffold for the repair of a mid-distal adjacent finger defect: a retrospective study.

PURPOSE: Assessing the clinical effectiveness of combining with the first dorsal (plantar) metatarsal artery pedicle free bilobed flap with a cell scaffold to repair mid-distal defects in adjacent fingers. METHODS: From September 2012 to April 2022, 21 patients with 42 mid-distal defects of adjacent fingers underwent treatment using combined with the first dorsal (plantar) metatarsal artery pedicle free bilobed flap with a cell scaffold. The flaps size ranged from 2.1 cm * 1.6 to 4.9 cm * 3.2 cm. Follow-up evaluations included assessing function, sensation, and appearance, etc. of the injured fingers and donor areas. RESULTS: All 42 flaps survived in 21 patients without any vascular crises, and the wounds healed in phase I. The mean follow-up time was 12.2 months (range 7-22 months). During follow-up, in injured fingers, according to the Michigan Hand Outcomes Questionnaire (MHOQ), the functional recovery and appearance were satisfactory; in Dargan Function Evaluation (DFE), the results were both "excellent" in fourteen patients, "excellent" and "good" in five patients, both "good" in one patient, "good" and "general" in one. In static two-point discrimination (2PD), the variation ranges from 4 to 9 mm in injured fingers and 6-10 mm in donor toes. Cold Intolerance Severity Score (CISS) is mild in all patients. The visual analogue score (VAS) showed no pain in the injured fingers and donor toes. No deformities or other complications were noted at the donor toes. According to Chinese Manchester Foot Pain and Disability Index (C-MFPDI), there was no morbidity on foot function in all donor areas. CONCLUSION: The surgical procedure of combined with the first dorsal (plantar) metatarsal artery pedicle free bilobed flap with a cell scaffold for the repair of mid-distal adjacent fingers defect is highly satisfactory. This approach helps the injured fingers to achieve good function, sensibility and appearance, while also achieving satisfactory results in the donor toes.

Mortality of children and adolescents co-infected with tuberculosis and HIV: a systematic review and meta-analysis.

OBJECTIVE: Children and adolescents with HIV infection are well known to face a heightened risk of tuberculosis. However, the exact mortality rates and temporal trends of those with HIV-tuberculosis (TB) co-infection remain unclear. We aimed to identify the overall mortality and temporal trends within this population. METHODS: PubMed, Web of Science, and Embase were employed to search for publications reporting on the mortality rates of children and adolescents with HIV-TB co-infection from inception to March 2, 2024. The outcome is the mortality rate for children and adolescents with HIV-TB co-infection during the follow-up period. In addition, we evaluate the temporal trends of mortality. RESULTS: During the follow-up period, the pooled mortality was 16% [95% confidence interval (CI) 13-20]. Single infection of either HIV or TB exhibit lower mortality rates (6% and 4%, respectively). We observed elevated mortality risks among individuals aged less than 12 months, those with extrapulmonary TB, poor adherence to ART, and severe immunosuppression. In addition, we observed a decreasing trend in mortality before 2008 and an increasing trend after 2008, although the trends were not statistically significant ( P  = 0.08 and 0.2 respectively). CONCLUSIONS: Children and adolescents with HIV-TB co-infection bear a significant burden of mortality. Timely screening, effective treatment, and a comprehensive follow-up system contribute to reducing the mortality burden in this population.

Brain development in newborns and infants after ECMO.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) not only significantly improves survival rates in severely ill neonates but also is associated with long-term neurodevelopmental issues. To systematically review the available literature on the neurodevelopmental outcomes of neonates and infants who have undergone ECMO treatment, with a focus on motor deficits, cognitive impairments, sensory impairments, and developmental delays. This review aims to understand the incidence, prevalence, and risk factors for these problems and to explore current nursing care and management strategies. DATA SOURCES: A comprehensive literature search was performed across PubMed, EMBASE, and Web of Science using a wide array of keywords and phrases pertaining to ECMO, neonates, infants, and various facets of neurodevelopment. The initial screening involved reviewing titles and abstracts to exclude irrelevant articles, followed by a full-text assessment of potentially relevant literature. The quality of each study was evaluated based on its research methodology and statistical analysis. Moreover, citation searches were conducted to identify potentially overlooked studies. Although the focus was primarily on neonatal ECMO, studies involving children and adults were also included due to the limited availability of neonate-specific literature. RESULTS: About 50% of neonates post-ECMO treatment exhibit varying degrees of brain injury, particularly in the frontal and temporoparietal white matter regions, often accompanied by neurological complications. Seizures occur in 18%-23% of neonates within the first 24 hours, and bleeding events occur in 27%-60% of ECMO procedures, with up to 33% potentially experiencing ischemic strokes. Although some studies suggest that ECMO may negatively impact hearing and visual development, other studies have found no significant differences; hence, the influence of ECMO remains unclear. In terms of cognitive, language, and intellectual development, ECMO treatment may be associated with potential developmental delays, including lower composite scores in cognitive and motor functions, as well as potential language and learning difficulties. These studies emphasize the importance of early detection and intervention of potential developmental issues in ECMO survivors, possibly necessitating the implementation of a multidisciplinary follow-up plan that includes regular neuromotor and psychological evaluations. Overall, further multicenter, large-sample, long-term follow-up studies are needed to determine the impact of ECMO on these developmental aspects. CONCLUSIONS: The impact of ECMO on an infant's nervous system still requires further investigation with larger sample sizes for validation. Fine-tuned management, comprehensive nursing care, appropriate patient selection, proactive monitoring, nutritional support, and early rehabilitation may potentially contribute to improving the long-term outcomes for these infants.

Non-pharmacological interventions for preventing suicide attempts: A systematic review and network meta-analysis.

Suicide attempts can cause serious physical harm or death. It would be crucial to gain a better understanding of the comparative efficacy of non-pharmacological interventions. We aimed to identify which non-pharmacological interventions are more effective in preventing suicide attempts. PubMed, Web of Science, and EMBASE databases were searched systematically from their inception until 3 April 2023. To be eligible for inclusion, randomized controlled trials (RCTs) had to meet the following criteria: Participants were individuals who had suicidal ideation or a history of severe self-harm or attempted suicide. A network meta-analysis was performed using a random effects model to estimate the treatment effect of various non-pharmacological interventions. (PROSPERO registration number: CRD42023411393). We obtained data from 54 studies involving 17,630 participants. Our primary analysis found that Cognitive therapy (CT) (OR=0.19, 95%CI =0.04-0.81), Dialectical Behavior Therapy (DBT) (OR=0.37, 95%CI =0.13-0.97), Cognitive-behavioral therapy (CBT) (OR=0.42, 95%CI =0.17-0.99), and Brief intervention and contact (BIC) (OR=0.65, 95%CI=0.44-0.94) were superior to TAU (within the longest available follow-up time) in preventing suicide attempts, while other intervention methods do not show significant advantages over TAU. Secondary analysis showed that the two intervention measures (CT and BIC) were effective when follow-up time did not exceed 6 months, but there was no effective intervention measure with longer follow-up times. CT, DBT, CBT, and BIC have a better effect in preventing suicide attempts than other non-pharmacological interventions. Additional research is necessary to validate which interventions, as well as which combinations of interventions, are the most effective.

Suicide death, suicidal ideation and suicide attempt in patients with diabetes: A systematic review and meta-analysis.

AIMS: Diabetes has been indicated to be a risk factor for suicide. We aim to estimate the prevalence of suicide in patients with diabetes. DESIGN: A meta-analysis using PRISMA methodology was adopted to examine the incidence of suicide in diabetic patients. DATA SOURCES: From inception to October 2022, three online databases (PubMed, China National Knowledge Infrastructure and Web of Science) were used to search studies. REVIEW METHODS: We used random-effects model to analysis. And our primary outcome was the incidence of suicide death per 100 person-years, and other outcomes were prevalence of suicidal ideation and suicide attempt. To explore the sources of heterogeneity in our study, we performed subgroup and meta-regression analyses. RESULTS: The suicide death rate in diabetic patients was 0.027 per 100 person-years, with a higher rate for Type 1 Diabetes Mellitus compared to Type 2 Diabetes Mellitus. The prevalence of suicidal ideation in diabetes patients was 0.175, with a higher prevalence in Type 1 Diabetes Mellitus compared to Type 2 Diabetes Mellitus. The prevalence of suicide attempts in diabetes patients was 0.033, indicating a higher rate for Type 2 Diabetes Mellitus compared to Type 1 Diabetes Mellitus. CONCLUSIONS: The results indicate a high rate of suicide among people with diabetes, and this study identifies populations and regions at high risk for suicide. Our review emphasizes interventions in mental health and the improvement of suicide prevention programmes. IMPACT: The study investigated suicide death, suicidal ideation and suicide attempt in diabetic individuals. Suicide rates are elevated among diabetic patients, and various patient groups face distinct suicide risks. It is important to prioritize the mental well-being of diabetic individuals and enhance interventions, including personalized approaches, to inform public health efforts aimed at preventing and addressing suicide among diabetic patients. PATIENT OR PUBLIC CONTRIBUTION: No patient or public involvement.

Effect of Socioeconomic Disparities on Suicide Risk in Patients With Prostate Cancer During 2005 to 2020: A Population Study.

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.

Targeting the Main Sources of Reactive Oxygen Species Production: Possible Therapeutic Implications in Chronic Pain.

Humans have long been combating chronic pain. In clinical practice, opioids are first- choice analgesics, but long-term use of these drugs can lead to serious adverse reactions. Finding new, safe and effective pain relievers that are useful treatments for chronic pain is an urgent medical need. Based on accumulating evidence from numerous studies, excess reactive oxygen species (ROS) contribute to the development and maintenance of chronic pain. Some antioxidants are potentially beneficial analgesics in the clinic, but ROS-dependent pathways are completely inhibited only by scavenging ROS directly targeting cellular or subcellular sites. Unfortunately, current antioxidant treatments donot achieve this effect. Furthermore, some antioxidants interfere with physiological redox signaling pathways and fail to reverse oxidative damage. Therefore, the key upstream processes and mechanisms of ROS production that lead to chronic pain in vivo must be identified to discover potential therapeutic targets related to the pathways that control ROS production in vivo. In this review, we summarize the sites and pathways involved in analgesia based on the three main mechanisms by which ROS are generated in vivo, discuss the preclinical evidence for the therapeutic potential of targeting these pathways in chronic pain, note the shortcomings of current research and highlight possible future research directions to provide new targets and evidence for the development of clinical analgesics.

The tRNA-GCN2-FBXO22-axis-mediated mTOR ubiquitination senses amino acid insufficiency.

Mammalian target of rapamycin complex 1 (mTORC1) monitors cellular amino acid changes for function, but the molecular mediators of this process remain to be fully defined. Here, we report that depletion of cellular amino acids, either alone or in combination, leads to the ubiquitination of mTOR, which inhibits mTORC1 kinase activity by preventing substrate recruitment. Mechanistically, amino acid depletion causes accumulation of uncharged tRNAs, thereby stimulating GCN2 to phosphorylate FBXO22, which in turn accrues in the cytoplasm and ubiquitinates mTOR at Lys2066 in a K27-linked manner. Accordingly, mutation of mTOR Lys2066 abolished mTOR ubiquitination in response to amino acid depletion, rendering mTOR insensitive to amino acid starvation both in vitro and in vivo. Collectively, these data reveal a novel mechanism of amino acid sensing by mTORC1 via a previously unknown GCN2-FBXO22-mTOR pathway that is uniquely controlled by uncharged tRNAs.

The connection between six common air pollution particles and adult brain tumors: a meta-analysis of 26,217,930 individuals.

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.

Explaining nitrogen turnover in sediments and water through variations in microbial community composition and potential function.

Anthropogenic activities greatly impact nitrogen (N) biogeochemical cycling in aquatic ecosystems. High N concentrations in coastal aquaculture waters threaten fishery production and aquaculture ecosystems and have become an urgent problem to be solved. Existing microbial flora and metabolic potential significantly regulate N turnover in aquatic ecosystems. To clarify the contribution of microorganisms to N turnover in sediment and water, we investigated three types of aquaculture ecosystems in coastal areas of Guangdong, China. Nitrate nitrogen (NO3--N) was the dominant component of total nitrogen in the sediment (interstitial water, 90.4%) and water (61.6%). This finding indicates that NO3--N (1.67-2.86 mg/L and 2.98-7.89 mg/L in the sediment and water) is a major pollutant in aquaculture ecosystems. In water, the relative abundances of assimilation nitrogen reduction and aerobic denitrifying bacteria, as well as the metabolic potentials of nitrogen fixation and dissimilated nitrogen in fish monoculture, were only 61.0%, 31.5%, 47.5%, and 27.2% of fish and shrimp polyculture, respectively. In addition, fish-shrimp polyculture reduced NO3--N content (2.86 mg/L) compared to fish monoculture (7.89 mg/L), which was consistent with changes in aerobic denitrification and nitrate assimilation, suggesting that polyculture could reduce TN concentrations in water bodies and alleviate nitrogen pollution risks. Further analysis via structural equation modeling (SEM) revealed that functional pathways (36% and 31%) explained TN changes better than microbial groups in sediment and water (13% and 11%), suggesting that microbial functional capabilities explain TN better than microbial community composition and other factors (pH, O2, and aquaculture type). This study enhances our understanding of nitrogen pollution characteristics and microbial community and functional capabilities related to sediment-water nitrogen turnover in three types of aquaculture ecosystems, which can contribute to the preservation of healthy coastal ecosystems.

Impact of the National Nursing Development Plan on nursing human resources in China: An interrupted time series analysis for 1978-2021.

BACKGROUND: Shortages of nurses and unequal distribution of nursing staff have been huge challenges for global health services. OBJECTIVES: The aim of our study was to evaluate the impact of the National Nursing Development Plan on nursing human resources in China. METHODS: An interrupted time series design was used in this study. The data for this study were extracted from the National Health Statistics Yearbook from 1978 to 2021. The Ministry of Health issued the National Nursing Development Plan (2005-2010) in July 2005. Subsequently, the strategic plan was issued every 5 years: the National Nursing Development Plan (2011-2015), the National Nursing Development Plan (2016-2020), and the National Nursing Development Plan (2021-2025). This study used five indicators including 1) the number of registered nurses (RNs) in China, 2) the number of RNs per 1000 population in China, 3) the proportion of RNs in health technical personnel in China, 4) the doctor-nurse ratio and 5) the number of nurses working in primary medical institutions to evaluate the changing trend of nursing human resources in China from 1978 to 2021. RESULTS: Interrupted time series analysis showed that after the implementation of the National Nursing Development Plan (2005-2010), the building of nurses in China was gradually strengthening, and the number of RNs in China increased by 0.198 million per year (95%CI 0.174-0.223; P < 0.001); the number of RNs per 1000 population (Coefficient = 0.139; 95%CI 0.123-0.154; P < 0.001); the proportion of RNs in the total number of health professionals in China has increased from 29.6 % to 44.6 % (Coefficient = 0.010; 95%CI 0.009-0.010; P < 0.001); in China, the doctor-nurse ratio increased by 0.024 (95%CI 0.019-0.029; P < 0.001). In 2021, the number of RNs working in primary medical institutions increased by approximately 0.86 million compared with that in 2005, and the proportion of RNs in the country increased by 1.4 %. The development of nurses is especially tilted to the primary level to meet the health and nursing needs of the primary level. CONCLUSIONS: The implementation of the National Nursing Development Plan has greatly expanded the scale of nursing human resources in China and significantly optimized the efficiency of allocation.

TWEETABLE ABSTRACT: The implementation of the National Nursing Development Plan has greatly expanded the scale of nursing human resources in China and significantly optimized the efficiency of allocation.

Socioeconomic status on survival outcomes in patients with colorectal cancer: a cross-sectional study.

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.

Global trends and frontiers of research on total disc replacement: A bibliometric analysis.

With the increased risk of complications associated with traditional spinal fusion for the treatment of degenerative disc disease, total disc replacement (TDR) has received increasing attention in recent years. Despite the rapid development of its related research fields, its research status and the hotspot analysis are still unclear. Our goal was to identify and analyze the global research trends on TDR using bibliometric tools. All TDR data were obtained from the WoSCC. The information of research field was collected, including title, author, institutions, journals, countries, references, total citations, and years of publication for further analysis. From 1993 to 2022, a total of 1167 articles and 11,348 references were included in this field. These publications are mainly from 53 countries/regions and 174 journals, led by the United States and China. According to the citation report, the US was absolutely in the leading position in this research field. The most contribution institution and author were Sichuan University and Liu H. Spine and European Spine Journal were the most active journal on TDR research, with 205 and 118 articles. Meanwhile, they were also the most frequently cited journals. The "bone loss," "cervical arthroplasty," "hybrid surgery" were the most frequently cited areas of TDR research. Meanwhile, the latest research hotspots and directions were "cervical disc arthroplasty," "7 year follow up," "heterotopic ossification." The scientific research on TDR has increased considerably in recent years. This study clarifies the current research status and future development trends in order to guide clinicians and researchers in the field of TDR. It can be inferred that cervical disc arthroplasty and bone loss will be the research focus in the future.

Prevalence of suicidal ideation and correlated risk factors during the COVID-19 pandemic: A meta-analysis of 113 studies from 31 countries.

The purpose of this study was to estimate the prevalence of suicidal ideation and correlated risk factors during the COVID-19 pandemic. Web of Science (WOS) and PubMed were searched according to a pre-set strategy. A total of 132 studies were identified, 104 of which were included in the meta-analysis. The prevalence of suicidal ideation was approximately 14.7% (95%CI: 12.5%, 16.8%, P < 0.01) in the general population, approximately 22.4% (95%CI: 17.1%, 27.8%, P < 0.01）in adolescents, approximately 21.0% (95%CI: 12.8%, 29.2%, P < 0.01) in psychiatric patients, approximately 20.6% (95%CI: 18.7%, 22.5%, P < 0.01）in university students, approximately 18.9% (95%CI: 8.3%, 29.5%, P < 0.01) in younger adults, approximately 10.6% (95%CI: 1.0%, 20.2%, P = 0.031) in COVID-19 patients and approximately 7.4% (95%CI: 4.3%, 10.5%, P < 0.01) in healthcare workers. The prevalence in North America was approximately 16.0% (95%CI: 13.6%-18.4%, P < 0.001), approximately 14.5% in Asia (95%CI: 9.5%-19.4%, P < 0.001), approximately 10.5% in Europe (95%CI: 8.5%-12.4%, P < 0.001), and approximately 20.5% in South America (95%CI: 19.5%-21.5%, P < 0.001). The following were risk factors which might be correlated with suicidal ideation: severe anxiety symptoms, mild to moderate depression, a strong feeling of loneliness/social isolation, poor sleep quality, having COVID-19-related experience, having quarantine or lockdown experience, being female, being single or divorced, having financial problems and having a history of suicidal ideation/attempt. This article reports the prevalence of suicidal ideation and discussing potential risk factors during the pandemic among general population and vulnerable groups. Early detection and follow-up were necessary for the noteworthy population.
