Global trends and differences in the burden of alcohol use disorders attributable to childhood sexual abuse by sex, age, and socio-demographic index: Findings from the Global Burden of Disease Study 2019.

BACKGROUND: Childhood sexual abuse (CSA) is a severe global problem associated with alcohol use disorder (AUD). Previous studies have confirmed this relationship; however, there is a lack of research on the disease burden of AUD attributable to CSA. OBJECTIVE: To analyze global spatiotemporal trends and differences in the disease burden of AUD attributable to CSA and its relationship with age, sex, and the sociodemographic index (SDI). PARTICIPANTS AND SETTING: Data from the Global Burden of Disease 2019 Public Database. METHODS: Summary exposure value (SEV) was used to evaluate CSA. Disability-adjusted life year (DALY), years lived with disability (YLD), years of life lost (YLL), and their annual rates of change were used to evaluate disease burden. Cluster analysis based on Ward's method was used to examine the global burden associated with age, sex, and SDI. A 95 % uncertainty intervals (UI), excluding 0, was considered statistically significant. RESULTS: In 2019, 1.63 million (95 % UI 0.23-3.90 million) DALYs of AUD were caused by CSA and the age-standardized rates (ASRs) of DALY was 19.77 (95 % UI 2.78-47.46) globally. Annual rates of change in DALY of people over 65 years of age increased from 1990 to 2019 in all regions except the High-middle SDI regions. The ASRs of DALY of females in High SDI regions, were always at a much higher level than other SDI regions, and showed an upward trend from 1990 to 2019 (DALY 1990: 20.38 [95 % UI 2.87-47.77], 2019: 23.61 [95 % UI 3.55-54.94]). CONCLUSIONS: Substantial geographical differences were observed in the burden of AUD attributable to CSA. The level of CSA exposure was inconsistent with the related burden of AUD in different regions according to the sociodemographic index. The burden of disease increased in the elderly population and in females in high sociodemographic index regions.

Prevalence and associated factors of abortion among women with severe mental disorders.

BACKGROUND: Abortion behaviors among individuals with mental disorders presented major obstacles to women's health. However, few studies reported the prevalence and associated factors of abortion among women with severe mental disorders in China. Consequently, this study aims to investigate the prevalence of abortion among female patients in rural communities and identify potential health risks. METHOD: This was a cross-sectional study of 276 women aged 18 years and older with severe mental disorders in rural areas of Shandong Province, China. The pregnancy history, abortion history and socio-demographic characteristics of women were investigated by questionnaire. Logistic regression analysis was employed to examine the associated factors for different abortion behaviors. RESULT: The study showed that 82.61 % (228/276) of patients had a pregnancy history. Among the patients with a pregnancy history, 43.42 % (99/228) reported having had at least one abortion, and 15.79 % (36/228) had more than one. In the other side, 31.58 % (72/228) of them experienced spontaneous abortion, while 12.72 % (29/228) experienced induced abortion. Age at first gestation (aOR 0.80, 95 % CI 0.70-0.90) and age at last gestation (aOR 1.17, 95 % CI 1.07-1.27) were both associated with abortion. Anxiety was related to spontaneous (aOR 1.08, 95 % CI 1.02-1.15) and repeat abortions (aOR 1.10, 95 % CI 1.01-1.19). In addition, religion (aOR 10.47, 95 % CI 2.81-39.01), number of children≥2 (aOR 0.18, 95 % CI 0.04-0.77), and family functioning (aOR 1.31, 95 % CI 1.06-1.63) were associated with induced abortion. CONCLUSION: Women with severe mental disorders in rural regions have notably higher rates of abortion compared to the general female population, particularly for spontaneous abortions. Gestational age and anxiety of pregnant patients deserve attention and preventive measures to avoid the outcomes of abortion.

Differentiating the association between age of alcohol use initiation and conditional suicidal behaviors among adolescents.

INTRODUCTION: Suicide and early alcohol use initiation are public health concerns. Previous studies have explored the associations between age of alcohol use initiation and suicidal behaviors, which progresses from ideation to action. Distinguishing between the various associations can help gain a deeper understanding of suicidal behaviors and aid in developing social suicide prevention strategies. METHODS: The study utilized the Youth Risk Behavior Survey to investigate this association. A total of 17 209 students were finally included in the study. Conditional suicidal behaviors included no suicidal behavior (NS), suicidal ideation without a plan or attempt (SINPA), suicide plan without an attempt (SPNA) and suicide attempt (SA). RESULTS: Among 17 209 students, the prevalence of suicidal ideation, suicide plan, and suicide attempt were 21.4%, 17.3%, and 11.1%, respectively. Moreover, 15.2% of the students used alcohol before age 13, whereas 31.7% of students used alcohol at age 13 or older. Compared to NS, students using alcohol showed significant associations with SA (OR = 2.34, p < .001; OR = 1.29, p < .01), SPNA (OR = 1.68, p < .001; OR = 1.19, p < .05) and SINPA (OR = 1.55, p < .001; OR = 1.40, p < .001). Comparing with SINPA and SNPA, students using alcohol before age 13 were associated with SA (OR = 1.61, p < .001; OR = 1.46, p < .001), whereas those using alcohol at or after the age 13 were not associated with SA (OR = 0.98, p > .05; OR = 1.09, p > .05). DISCUSSION: This study demonstrated that early alcohol use initiation was significantly associated with suicide attempts among students with suicidal ideations or plans.

Global, regional and national burdens of bipolar disorders in adolescents and young adults: a trend analysis from 1990 to 2019.

Background: Bipolar disorder is identified as a cause of severe damage to the physical, psychological and social functioning of adolescents and young adults. Aims: The aim of this study is to ascertain the trends in the burden of bipolar disorder among individuals aged 10-24 years at global, regional and national levels from 1990 to 2019. Methods: The data analysed in this study were from the Global Burden of Diseases 2019. The numbers, rates per 100 000 population, average annual percentage changes (AAPCs) of incidence, prevalence and years lived with disability (YLDs) of bipolar disorder are reported at the global, regional and national levels among individuals aged 10-24 years. Global trends by age, sex and Social Development Index (SDI) were further analysed. Results: Globally, the incidence of bipolar disorder among adolescents and young adults increased from 79.21 per 100 000 population (95% uncertainty interval (UI): 58.13 to 105.15) in 1990 to 84.97 per 100 000 population (95% UI: 61.73 to 113.46) in 2019, AAPC 0.24 (95% confidence interval (CI): 0.22 to 0.26). In the past three decades, there has been an increase in incidence, prevalence and YLDs in both males and females. The largest increase in incidence between 1990 and 2019 was observed in those aged 20-24 years old (from 51.76 per 100 000 population (95% UI: 26.81 to 87.20) in 1990 to 58.37 per 100 000 population (95% UI: 30.39 to 98.55) in 2019; AAPC 0.42 (95% CI: 0.38 to 0.47)). By the SDI quintile, the largest increase in incidence was observed in the middle SDI; however, the high SDI countries had the highest incidence. Regionally, the largest increase in incidence was observed in southern Latin America. At the national level, the most pronounced increase in the incidence was in Greenland. Conclusions: The global increase in incidence among adolescents and young adults between 1990 and 2019 indicates that strategies to improve their mental health still need to be emphasised.

Risk of second cancer in esophageal squamous cell carcinoma and adenocarcinoma survivors: a population-based analysis in SEER dataset.

Background: Previous studies have reported increased risk of second cancer in both esophageal squamous cell cancer (ESCC) and esophageal adenocarcinoma (EAC) survivors. This study aimed to examine the risk and influential factors of second cancer in ESCC and EAC patients. Methods: This population-based cohort study included 7,297 ESCC patients and 11,812 EAC patients who were in 1992-2019 from the Surveillance, Epidemiology, and End Results (SEER) program in the United States. These patients were followed up until diagnosis of second cancer, death, or end of the study (December 31, 2019). We calculated standard incidence ratio (SIR) and 95% confidence interval (CI) of second cancer and performed competing-risk regression to estimate the subdistribution hazard ratios (sHR) comparing categories of patients' characteristics. Results: After a total of 49,509.38 person-years of follow-up, 431 (5.9%) ESCC patients and 636 (5.9%) EAC patients developed a second cancer. An overall increased risk of second cancer was observed in both ESCC patients (SIR: 1.66, 95% CI: 1.51-1.83) and EAC patients (SIR: 1.11, 95% CI: 1.02-1.20). ESCC patients were at increased risk of second malignancy in oral cavity and pharynx (SIR: 12.57, 95% CI: 9.87-15.79), stomach (SIR: 3.03, 95% CI: 1.77-4.85), nose and larynx (SIR: 4.79, 95% CI: 2.47-8.37), and lung and bronchus (SIR: 2.44, 95% CI: 1.96-2.99), but decreased risk of prostate cancer (SIR: 0.73, 95% CI: 0.52-0.99). EAC patients had increased risk of second malignancies in stomach (SIR: 4.41, 95% CI: 3.23-5.89), lung and bronchus (SIR: 1.26, 95% CI: 1.02-1.54), and kidney (SIR: 1.57, 95% CI: 1.05-2.25). The risk of second cancer was higher in female ESCC patients than in males (sHR: 1.34, 95% CI: 1.11-1.63) and decreased with more advanced tumor stage in both ESCC patients (sHR: 0.62, 95% CI: 0.50-0.76 for regional stage; sHR: 0.27, 95% CI: 0.20-0.36 for distant stage) and EAC patients (sHR: 0.47, 95% CI: 0.40-0.56 for regional stage; sHR: 0.10, 95% CI: 0.07-0.13 for distant stage). Conclusions: Both ESCC and EAC patients are at considerable risk of certain types of second cancer.

An innovative ensemble model based on deep learning for predicting COVID-19 infection.

Nowadays, global public health crises are occurring more frequently, and accurate prediction of these diseases can reduce the burden on the healthcare system. Taking COVID-19 as an example, accurate prediction of infection can assist experts in effectively allocating medical resources and diagnosing diseases. Currently, scholars worldwide use single model approaches or epidemiology models more often to predict the outbreak trend of COVID-19, resulting in poor prediction accuracy. Although a few studies have employed ensemble models, there is still room for improvement in their performance. In addition, there are only a few models that use the laboratory results of patients to predict COVID-19 infection. To address these issues, research efforts should focus on improving disease prediction performance and expanding the use of medical disease prediction models. In this paper, we propose an innovative deep learning model Whale Optimization Convolutional Neural Networks (CNN), Long-Short Term Memory (LSTM) and Artificial Neural Network (ANN) called WOCLSA which incorporates three models ANN, CNN and LSTM. The WOCLSA model utilizes the Whale Optimization Algorithm to optimize the neuron number, dropout and batch size parameters in the integrated model of ANN, CNN and LSTM, thereby finding the global optimal solution parameters. WOCLSA employs 18 patient indicators as predictors, and compares its results with three other ensemble deep learning models. All models were validated with train-test split approaches. We evaluate and compare our proposed model and other models using accuracy, F1 score, recall, AUC and precision metrics. Through many studies and tests, our results show that our prediction models can identify patients with COVID-19 infection at the AUC of 91%, 91%, and 93% respectively. Other prediction results achieve a respectable accuracy of 92.82%, 92.79%, and 91.66% respectively, f1-score of 93.41%, 92.79%, and 92.33% respectively, precision of 93.41%, 92.79%, and 92.33% respectively, recall of 93.41%, 92.79%, and 92.33% respectively. All of these exceed 91%, surpassing those of comparable models. The execution time of WOCLSA is also an advantage. Therefore, the WOCLSA ensemble model can be used to assist in verifying laboratory research results and predict and to judge various diseases in public health events.

Effects of Saccharomyces cerevisiae quorum sensing signal molecules on ethanol production in bioethanol fermentation process.

In this study, the concentrations of Saccharomyces cerevisiae quorum sensing signal molecules (QSMs) were determined, not to mention the exploration of the effects of exogenous S. cerevisiae QSMs on the sole fermentation of S. cerevisiae and co-fermentation of S. cerevisiae and Lactobacillus plantarum. The results showed that the concentrations of three signal molecules (2-phenylethanol (2-PE), tyrosol and tryptophan) produced by S. cerevisiae increased with a higher bacteria density, which tends to become stable up to 118.02, 32.05 and 1.93 mg/L respectively when cultivating for 144 h. Among the three signaling molecules, only 2-PE promoted the ethanol production capacity of S. cerevisiae. The ethanol concentration of the sole fermentation of S. cerevisiae loaded with 120 mg/L 2-PE reached 3.2 g/L in 9 h, which was 58.7% higher than that of the group without 2-PE addition. Moreover, 2-PE reduced the negative impact of L. plantarum on S. cerevisiae. Within 12 h of the co-fermentation of L. plantarum and S. cerevisiae, the ethanol concentration in the co-fermentation group loaded with 2-PE reached 5.6 g/L, similar to that in the group fermenting with sole S. cerevisiae, and the yeast budding rate was also restored to 28.51%. qRT-PCR results of S. cerevisiae which was in sole fermentation with 2-PE addition for 9 h showed that the relative expression levels of ethanol dehydrogenase gene ADH1 in S. cerevisiae decreased by 25% and the relative expression levels of MLS1, CIT2, IDH1,CIT1 decreased by 26%, 30%, 22%,18%, respectively, meant that the glyoxylic and tricarboxylic acid cycles were greatly inhibited, which promotes the accumulation of ethanol. The results of this study provide basic data for using QSMs more than antibiotics in the the prevention of contamination during the industrialized bioethanol production.

Reconstruction of Alzheimer's Disease Cell Model In Vitro via Extracted Peripheral Blood Molecular Cells from a Sporadic Patient.

The establishment of human-induced pluripotent stem cell (iPSC) models from sporadic Alzheimer's disease (sAD) patients is necessary and could potentially benefit research into disease etiology and therapeutic strategies. However, the development of sAD iPSC models is still limited due to the multifactorial nature of the disease. Here, we extracted peripheral blood mononuclear cells (PBMCs) from a patient with sAD and induced them into iPSC by introducing the Sendai virus expressing Oct3/4, Sox2, c-Myc, and Klf4, which were subsequently induced into neural cells to build the cell model of AD. Using alkaline phosphatase staining, immunofluorescence staining, karyotype analysis, reverse transcription-polymerase chain reaction (RT-PCR), and teratoma formation in vitro, we demonstrated that the iPSC derived from PMBCs (PBMC-iPSC) had a normal karyotype and potential to differentiate into three embryonic layers. Immunofluorescence staining and quantitative real-time polymerase chain reaction (qPCR) suggested that PBMC-iPSCs were successfully differentiated into neural cells. Detection of beta-amyloid protein oligomer (AßO), beta-amyloid protein 1-40 (Aß 1-40), and beta-amyloid protein 1-42 (Aß 1-42) indicated that the AD cell model was satisfactorily constructed in vitro. In conclusion, this study has successfully generated an AD cell model with pathological features of beta-amyloid peptide deposition using PBMC from a patient with sAD.

Zebrafish: A Promising Model for Evaluating the Toxicity of Carbon Dot-Based Nanomaterials.

Carbon dots (CDs) exhibit a wide range of desirable properties including excellent photoluminescence, photostability, and water solubility, making them ideally suitable for use in the context of drug delivery, bioimaging, and related biomedical applications. Before these CDs can be translated for use in humans, however, further research regarding their in vivo toxicity is required. Owing to their low cost, rapid growth, and significant homology to humans, zebrafish (Danio rerio) are commonly employed as in vivo model systems in the toxicity studies of nanomaterials. In the present report, our group employed a hydrothermal approach to synthesize CDs and then assessed their toxicity in zebrafish. The resultant CDs were roughly 2.4 nm spheroid particles that emitted strong blue fluorescence in response to the excitation at 365 nm. These CDs did not induce any evident embryonic toxicity or did cause any apparent teratogenic effects during hatching or development when dosed at 150 µg/mL. However, significant effects were observed in zebrafish embryos at CD concentrations >200 µg/mL, including pericardial and yolk sac edema, delayed growth, spinal cord flexure, and death. These high CD concentrations were further associated with the reduction in zebrafish larval locomotor activity and decreased dopamine levels, reduced frequencies of tyrosine hydroxylase-positive dopaminergic neurons, and multiple organ damage. Further studies will be required to fully understand the mechanistic basis for CD-mediated neurotoxicity, with such studies being essential to fully understand the translational potential of these unique nanomaterials.

Tanshinone IIA Attenuates Insulin Like Growth Factor 1 -Induced Cell Proliferation in PC12 Cells through the PI3K/Akt and MEK/ERK Pathways.

The insulin like growth factor 1 (IGF-1) and its receptor (IGF-1R) facilitate tumor proliferation and progression. Tanshinone IIA (TSN) is an active diterpene quinone isolated from the roots of the herbal plant Salvia miltiorrhiza. TSN inhibits the proliferation of various types of cancer cells but its role in the IGF-1R-induced proliferation of pheochromocytoma (PC12) cells and the potential mechanisms are largely unknown. This study aims to investigate the anti-proliferative effect of TSN in PC12 cells and its role on IGF-1R signaling transduction. PC12 cells were treated with IGF-1 with or without TSN, methyl thiazolytetrazolium (MTT) assay, and cell counting kit-8 and flow cytometry were used to evaluate the proliferation of PC12 cells. The role of TSN on the apoptosis of PC12 cells were detected by flow cytometry as well. The effects of TSN and IGF-1 on the phosphorylation of IGF-1R, protein kinase B (Akt), extracellular-signal related kinase 1/2 (ERK1/2) and other downstream targets were analyzed by Western blotting analysis. Our results showed that IGF-1 promoted the growth of PC12 cells in a dose-dependent manner and increased the phosphorylation of IGF-1R, whereas TSN attenuated the effect of IGF-1. Interestingly, TSN did not induce cell apoptosis in PC12 cells. Moreover, TSN attenuated the phosphorylation of Akt and ERK1/2 induced by IGF-1, and the phosphorylation of glycogen synthase kinase-3ß, forkhead box O3a (FOXO3a) and c-Raf were also inhibited by TSN. Furthermore, TSN inhibited cell growth induced by IGF-1 and blocked the activation of IGF-1R in SH-SY5Y cells. Taken together, TSN has an inhibitory effect on the proliferation of PC12 cells via down-regulation of the phosphorylated IGF-1R and its downstream signaling.

Facile preparation and dual responsive behaviors of starch-based hydrogel containing azo and carboxylic groups.

Starch-based hydrogel containing azo group (SHA) was prepared through radical cross-linking reaction among starch- and PVA-based macromonomers, acrylic acid (AA) and 4-acryloyoxyazobenzene (AHAB). AHAB was prepared through an acylation reaction between acryloyl chloride and 4-hydroxyazobenzene (p-HAB), which was obtained by the diazo coupling reaction between aniline and phenol. The structure of SHA was confirmed with Fourier transform infrared spectrometer, thermogravimetric analysis and UV-Visible spectroscopy. SHA displayed pH-sensitive swelling in buffer saline. SHA film also exhibited a reversible trans-cis-trans photoisomerization behavior when they were subjected to alternative UV and visible light irradiation or dark storage. The dual-responsive characteristic was easily to be tailored via varying the initial amount of AHAB or AA.

Safety and efficacy of chloral hydrate for conscious sedation of infants in the pediatric cardiovascular intensive care unit.

This study evaluates the safety and efficacy of chloral hydrate administration for the conscious sedation of infants in the pediatric cardiovascular intensive care unit (PCICU).We conducted a retrospective review of the charts of 165 infants with congenital heart disease who received chloral hydrate in our PCICU between January 2014 and December 2014. Chloral hydrate was administered orally or rectally to infants using doses of 50 mg/kg. We collected and analyzed relevant clinical parameters.The overall length of time to achieve sedation was ranged from 5 to 35 min (10.8 ±â€Š6.2 min); the overall mean duration of sedation was ranged from 15 to 60 min (33.5 ±â€Š11.3 min); and the overall mean length of time to return to normal activity was 10 min to 6 h (34.3 ±â€Š16.2 min). The length of the PCICU stay was ranged from 3 to 30 days (8.2 ±â€Š7.1 days). Physiologically, there were no clinically significant changes in heart rate, mean arterial pressure, respiratory rate, or peripheral oxygen saturation before, during, or after use of the chloral hydrate. There were no significant differences regarding sedative effects in the subgroups (cyanotic vs acyanotic group, with pulmonary infection vs without pulmonary infection group, and with pulmonary hypertension vs without pulmonary hypertension group).Our experience suggests that chloral hydrate is a safe and efficacious agent for conscious sedation of infants in the PCICU.

Platelet-derived growth factor-stimulated versican synthesis but not glycosaminoglycan elongation in vascular smooth muscle is mediated via Akt phosphorylation.

Proteoglycans are associated with the initiation of atherosclerosis due to their binding of apolipoproteins on lipid particles leading to retention in the vessel wall. The signaling pathways through which growth factors regulate the synthesis and structure of proteoglycans are potential therapeutic targets. Platelet-derived growth factor (PDGF) is present in atherosclerotic plaques and activates phosphorylation of the serine/threonine kinase Akt. We have investigated the role of Akt in the signaling pathways for proteoglycan core protein expression and elongation of glycosaminoglycan chains on proteoglycans secreted by human vascular smooth muscle cells. The pharmacological inhibitor of Akt phosphorylation, SN30978, blocked PDGF stimulated phosphorylation of Akt. SN30978 caused concentration dependent inhibition of PDGF stimulated radiosulfate incorporation into secreted proteoglycans and the response was blocked by the PDGF receptor antagonists Ki11502 and imatinib. Analysis of the size of the biglycan molecules by SDS-PAGE showed that PDGF increased the apparent size of biglycan but this effect on glycosaminoglycan chain elongation was blocked by Ki11502 but not by SN30978. PDGF also stimulated total protein core protein synthesis assessed as (35)S-methionine/cysteine incorporation and specifically the expression of versican mRNA. Both of these responses were blocked by SN30978. This data shows that PDGF-stimulated proteoglycan core protein synthesis but not glycosaminoglycan chain elongation is mediated via Akt phosphorylation. These data identify potential pathways for the development of agents which can pharmacologically regulate individual components of the synthesis of proteoglycans.
