Survival and disease burden analyses of occupational pneumoconiosis during 1958-2021 in Huangshi city, China: a retrospective cohort study.

BACKGROUND: Pneumoconiosis, a chronic disease stemming from prolonged inhalation of dust particles, stands as a significant global burden of occupational diseases. This study aims to investigate the survival outcomes of pneumoconiosis patients in Huangshi city, China, while also evaluating the disease burden on afflicted patients. METHODS: Data for this study were sourced from the Huangshi Center for Disease Control and Prevention. Survival analyses of pneumoconiosis patients were conducted employing life tables and the Kaplan-Meier method. The Cox proportional hazards models were deployed to identify factors influencing pneumoconiosis patients' survival duration. Competing risks models were employed to confirm the validity of the model outcomes. Additionally, in the disease burden assessment, disability-adjusted life years (DALYs) were computed for various demographic groups and time frames. RESULTS: A total of 5,641 pneumoconiosis cases, diagnosed in Huangshi City, Hubei Province between 1958 and 2021, were incorporated into the cohort analysis. The probability of mortality and the risk ratio increased with advancing age. Notably, the median survival time of stage III pneumoconiosis patients was significantly shorter compared with those in stages I and II. The Cox proportional hazards model and competing risks analyses underscored several significant factors influencing survival time, including dust exposure duration (HR = 1.197, 95% CI: 1.104-1.298), age at first diagnosis (HR = 3.149, 95% CI: 2.961-3.349), presence of silicosis (HR = 1.378, 95% CI: 1.254-1.515), and stage II-III pneumoconiosis (HR = 1.456, 95% CI: 1.148-1.848). Cumulatively, DALYs amounted to 7,974.35 person-years, with an average of 1.41 person-years. The period between 2000 and 2019 witnessed the highest disease burden. CONCLUSION: Our findings highlight the urgent need for improved prevention, earlier detection, and more effective management strategies for the occupational pneumoconiosis population. This study not only underscores the persistent issue of pneumoconiosis in industrial environments but also serves as a crucial call to action for policymakers and healthcare providers.

Cost-effectiveness analysis of antiretroviral drugs for treatment-naive HIV infection in China.

INTRODUCTION: Dolutegravir (DTG)-based regimen was included in the expanded formulary of China's National Free Antiretroviral Treatment Program at the end of 2021. Yet high price of DTG and lack of health economic evaluation in China present barriers for implementation of the regimen. The study aims to investigate the lifetime cost-effectiveness of DTG-based regimen for treatment-naive HIV infection in China. METHODS: A decision-analytic Markov model was used to obtain the costs and effectiveness of four regimens: Arm A, efavirenz (EFV)-based regimen; Arm B, DTG-based regimen; Arm C, elvitegravir/cobicistat/tenofovir alafenamide/emtricitabine (EVG/c/FTC/TAF) regimen; Arm D, abacavir/lamivudine/dolutegravir (ABC/3TC/DTG) regimen. The potential impact of national centralized drug procurement policy was assessed in scenario analysis. The results were further validated through sensitivity analysis. RESULTS: Compared with other three regimens, DTG-based regimen led to the fewest cumulative adverse reactions, opportunistic infections and deaths. Compared with EFV-based regimen, the base-case ICERs for DTG-based regimen were 13,357 (USD/QALY) and 13,424 (USD/QALY) from the healthcare system and societal perspective respectively. In the policy scenario analysis with the procurement price of DTG equal to that of LPV/r, DTG-based regimen would be dominant. The model results remained robust in sensitivity analyses. CONCLUSIONS: DTG-based regimen for treatment-naive patients is likely to be cost-effective and deserve wider implementation in China. This study strongly suggests the centralized procurement of DTG to minimize cost and maximize cost-effectiveness.

Association between long-term exposure to ambient air pollutants and the risk of tuberculosis: A time-series study in Nantong, China.

Background: Increasing evidence has shown that the risk of tuberculosis (TB) might be related to the exposure to air pollutants; however, the findings are inconsistent and studies on long-term air pollutant exposure and TB risk are scarce. This study aime to assess the relationship between monthly exposure to air pollution and TB risk in Nantong, China. Methods: We collected the time series data on the number of TB cases, as well as environmental and socioeconomic covariates from January 2005 to December 2020. The impact of air pollutant exposure on TB risk was evaluated using the distributed lag nonlinear model (DLNM). Stratified analyses were conducted to examine the effect modifications of sex and age on the association between air pollutants and TB risk. Sensitivity analyses were applied to test the stability of the model. Results: There were a total of 54,096 cases of TB in Nantong during the study period. In the single-pollutant model, for each 10 µg/m3 increase in concentration, the pooled relative risks (RRs) of TB reached the maximum to 1.10 (95% confidence interval (CI): 1.04-1.16, lag 10 months) for particulate matter with aerodynamic diameter less than 2.5 µm (PM2.5), 1.05 (95% CI: 1.01-1.10, lag 9 months) for particulate matter with aerodynamic diameter less than 10 µm (PM10), and 1.11 (95%CI: 1.04-1.19, lag 10 months) for nitrogen dioxide (NO2). Ozone (O3) did not show significant effect on TB risk. Effect modifications of sex and age on the association between air pollutants and TB risk were not observed. The multi-pollutant model results showed no significant variation compared with the single-pollutant model. Conclusions: Our study suggests that air pollutants pose a substantial threat to the TB risk. Reducing air pollution might be crucial for TB prevention and control.

Combined impacts of environmental and socioeconomic covariates on HFMD risk in China: A spatiotemporal heterogeneous perspective.

BACKGROUND: Understanding geospatial impacts of multi-sourced influencing factors on the epidemic of hand-foot-and-mouth disease (HFMD) is of great significance for formulating disease control policies tailored to regional-specific needs, yet the knowledge is very limited. We aim to identify and further quantify the spatiotemporal heterogeneous effects of environmental and socioeconomic factors on HFMD dynamics. METHODS: We collected monthly province-level HFMD incidence and related environmental and socioeconomic data in China during 2009-2018. Hierarchical Bayesian models were constructed to investigate the spatiotemporal relationships between regional HFMD and various covariates: linear and nonlinear effects for environmental covariates, and linear effects for socioeconomic covariates. RESULTS: The spatiotemporal distribution of HFMD cases was highly heterogeneous, indicated by the Lorenz curves and the corresponding Gini indices. The peak time (R2 = 0.65, P = 0.009), annual amplitude (R2 = 0.94, P<0.001), and semi-annual periodicity contribution (R2 = 0.88, P<0.001) displayed marked latitudinal gradients in Central China region. The most likely cluster areas for HFMD were located in south China (Guangdong, Guangxi, Hunan, Hainan) from April 2013 to October 2017. The Bayesian models achieved the best predictive performance (R2 = 0.87, P<0.001). We found significant nonlinear associations between monthly average temperature, relative humidity, normalized difference vegetation index and HFMD transmission. Besides, population density (RR = 1.261; 95%CI, 1.169-1.353), birth rate (RR = 1.058; 95%CI, 1.025-1.090), real GDP per capita (RR = 1.163; 95%CI, 1.033-1.310) and school vacation (RR = 0.507; 95%CI, 0.459-0.559) were identified to have positive or negative effects on HFMD respectively. Our model could successfully predict months with HFMD outbreaks versus non-outbreaks in provinces of China from Jan 2009 to Dec 2018. CONCLUSIONS: Our study highlights the importance of refined spatial and temporal data, as well as environmental and socioeconomic information, on HFMD transmission dynamics. The spatiotemporal analysis framework may provide insights into adjusting regional interventions to local conditions and temporal variations in broader natural and social sciences.

Population-level health and economic impacts of introducing Vaccae vaccination in China: a modelling study.

INTRODUCTION: Given the ageing epidemic of tuberculosis (TB), China is facing an unprecedented opportunity provided by the first clinically approved next-generation TB vaccine Vaccae, which demonstrated 54.7% efficacy for preventing reactivation from latent infection in a phase III trial. We aim to assess the population-level health and economic impacts of introducing Vaccae vaccination to inform policy-makers. METHODS: We evaluated a potential national Vaccae vaccination programme in China initiated in 2024, assuming 20 years of protection, 90% coverage and US$30/dose government contract price. An age-structured compartmental model was adapted to simulate three strategies: (1) no Vaccae; (2) mass vaccination among people aged 15-74 years and (3) targeted vaccination among older adults (60 years). Cost analyses were conducted from the healthcare sector perspective, discounted at 3%. RESULTS: Considering postinfection efficacy, targeted vaccination modestly reduced TB burden (~20%), preventing cumulative 8.01 (95% CI 5.82 to 11.8) million TB cases and 0.20 (0.17 to 0.26) million deaths over 2024-2050, at incremental cost-effectiveness ratio of US$4387 (2218 to 10 085) per disability adjusted life year averted. The implementation would require a total budget of US$22.5 (17.6 to 43.4) billion. In contrast, mass vaccination had a larger bigger impact on the TB epidemic, but the overall costs remained high. Although both preinfection and postinfection vaccine efficacy type might have a maximum impact (>40% incidence rate reduction in 2050), it is important that the vaccine price does not exceed US$5/dose. CONCLUSION: Vaccae represents a robust and cost-effective choice for TB epidemic control in China. This study may facilitate the practice of evidence-based strategy plans for TB vaccination and reimbursement decision making.

Risk factors associated with 30-day hospital readmissions among persons living with HIV in Nantong, China.

OBJECTIVE: To estimate 30-day hospital readmission rates among persons living with HIV (PLWH) at the Nantong Infectious Disease Hospital in China and analyse the related risk factors. METHODS: A single-centre retrospective cohort study was conducted. There were 894 PLWH records obtained from the electronic medical record (EMR) system at the Nantong Infectious Disease Hospital in China, from October 2013 to February 2018. The 30-day readmission rates were calculated, and the risk factors were analysed by generalised estimating equations (GEEs). RESULTS: A total of 1153 hospitalizations from 894 patients were recorded between October 2013 and February 2018. The median time of 30-day readmissions was 13 days (interquartile range (IQR), 6-23). The reasons for all causes, acquired immunodeficiency syndrome (AIDS)-defining illnesses (ADIs), and non-AIDS-defining infections (non-ADIs) were 9.08, 13.52, and 7.91%, respectively. The results from the GEE analysis demonstrated that the risk factors associated with 30-days readmissions were as follows: no antiretroviral therapy (ART) prior to hospitalisations (odds ratio (OR) = 1.90, 95% confidence interval (CI): 1.21-3.00), low CD4 counts (OR = 2.17, 95% CI: 1.33-3.54), and multiple comorbidities (OR = 6.45, 95% CI: 1.62-25.73). CONCLUSION: Early detection of HIV infection and early initiation of ART treatment are the keys to controlling 30-day readmissions.

An Observational Study on HIV and Syphilis Rates and Associated Risk Factors among Elderly Men in Wuxi, China.

BACKGROUND: Acquired Immune Deficiency Syndrome (AIDS) remains a nationwide health problem in China; there were a reported 1,045,000 people living with Human immunodeficiency virus (HIV)/AIDS by the end of October 2020, and the proportion of individuals aged 50 years and older living with HIV has also increased from 8% to 24% over the past two decades. METHODS: A cross-sectional study and an 1:2 matched case-control study were conducted from July to August 2016, in Wuxi city, eastern China. A total of 1,000 men aged 50 years and older completed a face-to-face interview regarding their AIDS-related knowledge and attitudes, as well as risk behaviors. RESULTS: Prevalence was 0.1% for HIV and 2% for syphilis. The awareness rate of AIDS-related knowledge among elderly men was 48.9% (range 40.7%-63.9%). The 1꞉2 matched case-control study indicated that only the AIDS-related attitudes were different between the two groups (χ2=8.726, P=0.013), the conditional logistic regression analysis indicated that scores of AIDS health knowledge were the only significant prognostic factor for the infection (HR=0.754 (0.569- 0.999), P=0.049). CONCLUSION: It was crucial to prevent HIV/AIDS and syphilis infections by improving the awareness of AIDS-related knowledge and changing related attitudes among the elderly. Further research aimed at identifying how these factors impact their sexual decision-making can shed valuable insight into further prevention program in this population.

The Impact of Customized Short Message Service on High-Risk Behaviors Among MSM in China, a Randomized Controlled Trial Study.

An individual based randomized controlled trial (RCT) was designed to evaluate the impact of a customized short message service (SMS) intervention on HIV-related high-risk behaviors among Men who have sex with men (MSM). In total, 631 HIV-negative MSM were enrolled at baseline and divided into intervention and control groups randomly. Nine months later, the intervention group who received additional customized SMS intervention reported significantly lower rates of multiple partners, unclear partner infection status and condomless anal intercourse compared to the control group who received the routine intervention only. Six months post stopping the SMS intervention, the rates of unclear partner infection status and condomless anal intercourse still remained lower report in the intervention group. Our study shown that the customized SMS interventions can significantly reduce the HIV-related high-risk behaviors among MSM and with sustained effects over a period of time.

Identification of novel lncRNAs associated with sensitivity of HIV antiretroviral therapy: A two-stage matched case-control study.

BACKGROUND: To identify long non-coding RNAs (lncRNAs) that may be used as potential biomarkers of sensitivity to antiretroviral therapy (ART) against human immunodeficiency virus (HIV) infection. METHOD: A two-stage matched case-control study was conducted. First, in the screening stage, peripheral blood lymphocytes (PBLs) of six subjects receiving lamivudine-based ART (3 ART-resistant and 3 ART-sensitive subjects with matching durations of ART) were subjected to comprehensive microarray expression profiling in order to screen out lncRNAs associated with ART sensitivity. Secondly, during the validation stage, promising lncRNAs were evaluated via a 1:4 matched case-control study using 50 subjects (10 ART-resistant and 40 ART-sensitive subjects with matching durations of ART). RESULTS: Seven lncRNAs were screened out (P < 1.06 × 10-3) in the first stage. Among these, two lncRNAs (n341598 and n407911) survived validation conducted at the second stage (n341598: P < 0.001; n407911: P = 0.007), while another lncRNA n406445 showed marginally significant (P = 0.049). All three showed higher expression in ART-resistant subjects compared to that in ART-sensitive subjects. The area under the ROC curve (AUC) for n341598 was 0.867 (95 % CI: 0.796-0.966; P < 0.001), which was better than that for n406445 (0.702) and n407911 (0.780). Meanwhile, the AUC for n341598 was better than that of any combination of the three lncRNAs. CONCLUSION: Our study identified three highly expressed lncRNAs in patients with HIV ART-resistant, among which the lncRNA n341598 may be utilized as an optimal biomarker to distinguish ART-resistant and ART-sensitive patients. Further studies aimed at revealing the molecular mechanisms underlying the regulation of ART sensitivity by n341598 are warranted to complement our findings.

Self-efficacy mediates the associations of diabetes distress and depressive symptoms with type 2 diabetes management and glycemic control.

BACKGROUND: Adults with type 2 diabetes (T2D) often experience two common diabetes-related psychological distress: diabetes distress and depressive symptoms. Both are associated with adverse diabetes outcomes including poor self-management and glycemic control. However, diabetes distress and depressive symptoms differ in their associations with diabetes outcomes in T2D patients. OBJECTIVE: This study proposes a hypothetical model to examine whether self-efficacy mediates the adverse effects of depressive symptoms and/or diabetes distress on self-care behaviors and glycemic control. Additionally, we examined the bi-directional relationships between diabetes distress and depressive symptoms to identify potential underlying mechanisms. METHODS: This study conducted in 15 rural health clinics in Jiangsu province China. 900 adults with T2D participated in the prospective cohort study. The data Diabetes distress (the 17-item Diabetes Distress Scale, DDS17), depressive symptoms(the 10-item Center for Epidemiologic Studies Depression Scale, CESD-10), self-efficacy, self-care behaviors (diet and physical activity), metabolic variables (fasting plasma glucose, FPG) and demographic characteristics were assessed at baseline. Subsequent 12-month Hemoglobin A1C (HbA1c) were measured after baseline. Hierarchical multiple regression and bootstrap mediation analysis were used to test the effects and pathways among these associations. RESULTS: Of 843 participants (93.67%) of total cohort with available subsequent 12-month HbA1c levels, mean age was 66.08 years and 66.55% were women, 25.15% of them had depressive symptoms (CES-D ≥ 10), 12.20% had moderate diabetes distress (mean DDS ≥2) and 4.98% had the both two psychological distress. Hierarchical multiple regression showed higher DDS score significantly predicted unhealthy diet(ß = -1.10, P < 0.001) but not physical activities, while CESD score was negatively associated with physical activity (ß = -0.06, P < 0.001) but not diet. No independent effects of the two psychological distress variables on subsequent 12-month HbA1c were observed. Mediation analysis supported that elevated self-efficacy solely mediated the negative effect of both diabetes distress and depressive symptoms on diet (DDS score: ß = -0.238, 95 BCE% CI [-0.350, -0.141]; CESD score: ß = -0.010, 95 BCE% CI [-0.016, -0.005]), physical activities (DDS score: ß = -0.446, 95 BCE% CI [-0.630, -0.283]; CESD score: ß = -0.019, 95 BCE% CI [-0.030, -0.010]) and subsequent 12-month HbA1c (DDS score: ß = 0.105, 95 BCE% CI [0.030,0.189]; CESD score: ß = 0.004, 95 BCE% CI [0.001,0.009]). Additionally, the interplay of diabetes distress and depressive symptoms exerts their effects on diabetes outcomes directly and indirectly via self-efficacy. CONCLUSIONS: Self-efficacy may contribute to better diabetes outcomes and ameliorate negative effects of diabetes distress and depressive symptoms.

Assessment of low-dose paranasal sinus CT imaging using a new deep learning image reconstruction technique in children compared to adaptive statistical iterative reconstruction V (ASiR-V).

PURPOSE: To compare the effects of deep learning image reconstruction (DLIR) and adaptive statistical iterative reconstruction V (ASiR-V) on image quality in low-dose computed tomography (CT) of paranasal sinuses in children. METHODS: Low-dose CT scans of the paranasal sinuses in 25 pediatric patients were retrospectively evaluated. The raw data were reconstructed with three levels of DLIR (high, H; medium, M; and low, L), filtered back projection (FBP), and ASiR-V (30% and 50%). Image noise was measured in both soft tissue and bone windows, and the signal-to-noise ratios (SNRs) and contrast-to-noise ratios (CNRs) of the images were calculated. Subjective image quality at the ethmoid sinus and nasal cavity levels of the six groups of reconstructed images was assessed by two doctors using a five-point Likert scale in a double-blind manner. RESULTS: The patients' mean dose-length product and effective dose were 36.65 ± 2.44 mGy·cm and 0.17 ± 0.03 mSv, respectively. (1) Objective evaluation: 1. Soft tissue window: The difference among groups in each parameter was significant (P < 0.05). Pairwise comparisons showed that the H group' s parameters were significantly better (P < 0.05) than those of the 50% post-ASiR-V group. 2. Bone window: No significant between-group differences were found in the noise of the petrous portion of the temporal bone or its SNR or in the noise of the pterygoid processes of the sphenoids or their SNRs (P > 0.05). Significant differences were observed in the background noise and CNR (P < 0.05). As the DLIR intensity increased, image noise decreased and the CNR improved. The H group exhibited the best image quality. (2) Subjective evaluation: Scores for images of the ethmoid sinuses were not significantly different among groups (P > 0.05). Scores for images of the nasal cavity were significantly different among groups (P < 0.05) and were ranked in descending order as follows: H, M, L, 50% post-ASiR-V, 30% post-ASiR-V, and FBP. CONCLUSION: DLIR was superior to FBP and post-ASiR-V in low-dose CT scans of pediatric paranasal sinuses. At high intensity (H), DLIR provided the best reconstruction effects.

Comparison of different obesity indices associated with type 2 diabetes mellitus among different sex and age groups in Nantong, China: a cross-section study.

BACKGROUND: Obesity is associated with type 2 diabetes mellitus (T2DM). However, the obesity index that is most closely related to type 2 diabetes remains controversial. Therefore, the aim of this study was to compare the associations of five anthropometric indices (body mass index [BMI], body adiposity index, waist circumference [WC], waist-to-hip ratio, and waist-to-height ratio [WHtR]) with T2DM among Chinese adults divided into four groups according to sex and age. METHODS: A total of 4007 adult participants (1669 men and 2338 women) were included in the study. Odds ratios (ORs) and 95% confidence intervals were used with binary logistic regression models to estimate the risk of T2DM for each obesity index. Furthermore, we compared the area under the receiver operating characteristic curve (AUC) of each obesity index for the criterion of T2DM under the influence of risk factors. RESULTS: WC had the highest OR (3.211 and 1.452) and AUC (0.783 and 0.614) in both age groups of men. However, WHtR (OR = 2.366, AUC = 0.771) and BMI (OR = 1.596, AUC = 0.647) were the optimal criteria for predicting T2DM among females in the 18-59 and ≥ 60 years age groups, respectively. CONCLUSIONS: This study suggests that there is a positive association between obesity-related anthropometric indices and T2DM in different sex and age groups. WC appears to be the optimal anthropometric index for predicting T2DM in men. The optimal obesity indices related to T2DM were WHtR and BMI for women aged 18-59 and ≥ 60 years, respectively.

A novel regQTL-SNP and the risk of lung cancer: a multi-dimensional study.

RegQTL, a novel concept, indicates that different genotypes of some SNPs have differential effects on the expression patterns of miRNAs and their target mRNAs. We aimed to identify the association between regQTL-SNPs and lung cancer risk and to explore the underlying mechanisms. The two-stage case-control study included the first stage in a Chinese population (626 lung cancer cases and 667 healthy controls) and the second stage in a European population (18,082 lung cancer cases and 13,780 healthy controls). Functional annotations were conducted based on the GTEx and the TCGA databases. Functional experiments were performed to explore the underlying biological mechanisms in vitro and vivo. After strict screening, five candidate regQTL-SNPs (rs7110737, rs273957, rs6593210, rs3768617, and rs6836432) were selected. Among them, the variant T allele of rs3768617 in LAMC1 was found to significantly increase the risk of lung cancer (first stage: P = 0.044; second stage: P = 0.007). The eQTL analysis showed that LAMC1 expression level was significantly higher in subjects with the variant T allele of rs3768617 (P = 1.10 × 10-14). In TCGA paired database, the regQTL annotation indicated the different expression patterns between LAMC1 and miRNA-548b-3p for the distinct genotypes of rs3768617. Additionally, LAMC1 knockdown significantly inhibited malignant phenotypes in lung cancer cell lines and suppressed tumor growth. A novel regQTL-SNP, rs3768617, might affect lung cancer risk by modulating the expression patterns of miRNA-548b-3p and LAMC1. RegQTL-SNPs could provide a new perspective for evaluating the regulatory function of SNPs in lung cancer development.

Acupuncture Reduced the Risk for Insomnia in Stroke Patients: A Propensity-Score Matched Cohort Study.

Background: Post-stroke insomnia (PSI) affects the quality of life for stroke patients, reduces the likelihood of successful rehabilitation, and produces additional complications following stroke. Previous reports have provided some information regarding PSI risk factors, but little is known concerning protective factors for PSI. This study analyzed the relationship between acupuncture and insomnia in stroke patients and explored the use of acupuncture as a preventive treatment. Methods: Patients diagnosed with stroke from 2010 to 2019 were identified in the case database of the First Affiliated Hospital of Guangzhou University of Chinese These patients followed until 2020, and numerous factors were examined, including gender, age, stroke type, stroke location, and baseline comorbidities. A 1:1 propensity score was used to match an equal number of patients receiving acupuncture with stroke patients who did not receive acupuncture (N = 1,680 for each group). The purpose of the study was to compare the incidence of insomnia in these two stroke cohorts. We used the Cox regression model and Kaplan-Meier method to estimate the risk of insomnia as the outcome event. Results: Compared with the non-acupuncture cohort in general, stroke patients who received acupuncture treatment exhibited a lower risk of insomnia after adjusting for age, gender, stroke type, stroke location, and comorbidities (adjusted hazard ratio HR = 0.27, 95% confidential interval = 0.23 to 0.32). Acupuncture also reduced the risk of PSI for both genders. The respective risks were HR = 0.28 (adjusted) for males and HR = 0.26 (adjusted) for females. Acupuncture also lowered the risk for PSI for different age groups. The risks were HR = 0.22 (adjusted) for individuals 18 to 39 years of age, HR = 0.31 (adjusted) for individuals 40 to 59 years of age, HR = 0.28 (adjusted) for those 60 to 79 years of age, and HR = 0.18 (adjusted) for individuals 80 years of age and older. Concerning the stroke type, regardless of whether the stroke was ischemic, hemorrhagic, or a combination of the two stroke types, patients who received acupuncture exhibited lower risk (adjusted HR = 0.28, 0.17, and 0.49, respectively). Concerning stroke location, except for the cerebral hemispheres (adjusted HR = 1.10, 95% confidential interval = 0.12 to 1.01), the risk of PSI after receiving acupuncture was lower for the frontal lobe (adjusted HR = 0.42), the basal ganglia (adjusted HR = 0.22), the radiation crown (adjusted HR = 0.42), the diencephalon (adjusted HR = 0.20), or multiple partial strokes (adjusted HR = 0.26), the risk of PSI after receiving acupuncture was lower. For all baseline complications, acupuncture reduced the risk of insomnia. The cumulative incidence of insomnia in the acupuncture cohort was significantly lower than the non-acupuncture cohort (log-rank test, P = 0.000). Limitations: First, our research only included patients from a single center. Second, we did not classify the post-stroke insomnia severity. Second, the information was extracted manually. Overall, the sample size was small, and we needed to increase the sample size to strengthen the conclusions. Conclusion: Acupuncture treatment reduced the risk of insomnia in stroke patients. Future research be conducted with increased sample sizes and further elaboration on the specific acupuncture protocols that were used.

Assessment of Hearing Screening Combined With Limited and Expanded Genetic Screening for Newborns in Nantong, China.

Importance: Early identification and intervention for newborns with hearing loss (HL) may lead to improved physiological and social-emotional outcomes. The current newborn hearing screening is generally beneficial but improvements can be made. Objective: To assess feasibility and evaluate utility of a modified genetic and hearing screening program for newborn infants. Design, Setting, and Participants: This population-based cohort study used a 4-stage genetic and hearing screening program at 6 local hospitals in Nantong city, China. Participants were newborn infants born between January 2016 and June 2020 from the Han population. Statistical analysis was performed from April 1 to May 1, 2021. Exposures: Limited genetic screening for 15 variants in 4 common HL-associated genes and newborn hearing screening (NHS) were offered concurrently to all newborns. Hearing rescreening and/or diagnostic tests were provided for infants with evidence of HL on NHS or genetic variants on screening. Expanded genetic tests for a broader range of genes were targeted to infants with HL with negative results of limited genetic tests. Main Outcomes and Measures: The detection capability for infants with hearing impairment who passed conventional hearing screening, as well as infants with normal hearing at risk of late-onset HL due to genetic susceptibility. Results: Among a total of 35 930 infants, 32 512 infants completed the follow-up and were included for analysis. Among the infants included in the analysis, all were from the Han population in China and 52.3% (16 988) were male. The modified genetic and hearing screening program revealed 142 cases of HL and 1299 cases of genetic variation. The limited genetic screening helped identify 31 infants who passed newborn hearing screening, reducing time for diagnosis and intervention; 425 infants with normal hearing with pathogenic SLC26A4 variation and 92 infants with MT-RNR1 variation were at risk for enlarged vestibular aqueduct and aminoglycoside-induced ototoxicity respectively, indicating early aversive or preventive management. Conclusions and Relevance: This study found that performing modified genetic and hearing screening in newborns was feasible and provides evidence that the program could identify additional subgroups of infants who need early intervention. These findings suggest an advantage for universal adoption of such a practice.

Quercetin alleviates chronic renal failure by targeting the PI3k/Akt pathway.

Chronic renal failure (CRF) threatens human health greatly and attracts worldwide concerns of health professionals in the public health sector. In our preliminary study, we found that Compound capsule (Shengqing Jiangzhuo Capsule, SQJZJN) had a significant therapeutic effect on CRF. Quercetin is one of the main components of this Compound capsule. In this study, we investigated the effect of Quercetin monomer on CRF and the regulation of PI3k/Akt pathway. Network pharmacology analysis methods were employed to analyze the SQJZJN/Quercetin/PIK3R1 network relationships. In this study, a CRF rat model was prepared using the gavage adenine solution method and detected the indicators of Creatinine (Cr), Blood Urea Nitrogen (BUN), and Uric Acid (UA). After treating the rat model with Quercetin and PIK3R1-interfering lentivirus, respectively, we observed the changes on the histological morphology of the kidney and detected apoptosis using TUNEL staining. Gene and protein expression associated with renal function were detected using qPCR, WB and immunofluorescence. Quercetin was identified as the main ingredient of SQJZJN by the network pharmacological screening and Quercetin at 1.5 and 3 g/(kg.d) concentrations could effectively alleviate the CRF symptoms, reduce the levels of Cr, BUN, and UA, and markedly inhibit cell apoptosis demonstrated by the intragastric administration. Furthermore, the protein expression of p-PI3K, p-AKT, NLRP3, caspase1, AQP1, and AQP2 in all groups was detected by immunofluorescence and western blot assays, indicating that Quercetin could reduce the expression of NLRP3, caspase1, p-PI3k, and p-Akt, and increase the expression of AQP1 and AQP2 in the renal tissues of CRF rats. Being labeled with biotin and incubated with the total protein extracted from kidney tissues, Quercetin could bind to PIK3R1. Following the PIK3R1 interference lentivirus was injected into the CRF model rats by tail vein, the CRF symptoms were effectively alleviated in the PIK3R1 interference group, consistent with the effect of Quercetin. Taken together, Quercetin, a major component of SQJZJN, might minimize renal fibrosis and apoptosis in CRF rats by inhibiting the PI3k/Akt pathway through targeting PIK3R1. By regulating AQP1 and AQP2, both water retention and toxin accumulation were reduced.

Auricular acupressure promotes uterine involution after cesarean section: A randomized controlled trial.

BACKGROUND: Postpartum subinvolution of the uterus is a more common condition after cesarean section. Auricular acupressure (AA) is widely used for the treatment of postpartum diseases. However, few studies have explored the effects of AA as a treatment of uterine involution following cesarean section to date. This study aimed to assess the efficacy and safety of AA for uterine involution after cesarean section. METHODS: A total of 109 women who underwent cesarean section participated in this study. They were randomly allocated to either real AA or sham AA in a 1:1 ratio by a computer program. For 3 days, the real AA and sham AA groups received treatment 3 times daily. A series of assessments at 42 days after cesarean section, namely on the uterine size, the incidence of hydrometra, the first anal exsufflation time, bleeding volume at 6 hours, bleeding volume at 6-24 hours along with other general assessments were carried out. RESULTS: A total of 89 women completed the study. The uterine size at 42 days after a cesarean section was 6.3 cm smaller in the real AA group than in the sham AA group (P < 0.01). The incidence of hydrometra on day 42 postpartum was lower in the real AA group than in the sham AA group (P < 0.01). The lochia duration and the first anal exsufflation time after cesarean section were shorter in the real AA group than in the sham AA group (P < 0.05). CONCLUSION: AA improves uterine involution after cesarean section. TRIAL REGISTRATION: ChiCTR1800015569.

[Effect of rehabilitation robot rehabilitation training synchronizing acupuncture exercise therapy on postoperative rehabilitation with hip fracture].

OBJECTIVE: To compare the therapeutic effect between rehabilitation robot rehabilitation training synchronizing acupuncture exercise therapy and simple acupuncture exercise therapy on lower limb function and life activity ability for postoperative patients with hip fracture. METHODS: A total of 50 elderly postoperative patients with hip fracture were randomly divided into an observation group and a control group, 25 cases in each group. Both groups were treated with acupuncture at hip three points of the affected side and lateral line 1 of vertex, anterior oblique parietotemporal line of the healthy side, hip three needles were retained for 30 min. The scalp acupuncture needles were continue retained, the observation group was given acupuncture exercise therapy to synchronize lower limb rehabilitation robot rehabilitation training, and the control group was given acupuncture exercise therapy. The two groups were treated once a day, 7 times as a course of treatment, and totally 4 courses were required. The Harris score, Barthel index score and quadriceps femoris isokinetic muscle strength indexes [peak torque (PT), average power (AP), flexor peak torque/extensor peak torque (F/E)] were compared between the two groups before and after treatment. RESULTS: After treatment, the Harris score, Barthel index score, PT and AP were higher than those before treatment (P<0.05), and F/E was lower than that before treatment in the two groups (P<0.05). After treatment, the Harris score, Barthel index score, PT and AP in the observation group were higher than those in the control group (P<0.05), and the F/E in the observation group was lower than that in the control group (P<0.05). CONCLUSION: Rehabilitation robot rehabilitation training of lower limbs synchronizing acupuncture exercise therapy could enhance the hip joint activity function and quadriceps muscle group function of elderly postoperative patients with hip fracture, and effectively improve the lower limb function and life activity ability.

Further engineering of R. toruloides for the production of terpenes from lignocellulosic biomass.

BACKGROUND: Mitigation of climate change requires that new routes for the production of fuels and chemicals be as oil-independent as possible. The microbial conversion of lignocellulosic feedstocks into terpene-based biofuels and bioproducts represents one such route. This work builds upon previous demonstrations that the single-celled carotenogenic basidiomycete, Rhodosporidium toruloides, is a promising host for the production of terpenes from lignocellulosic hydrolysates. RESULTS: This study focuses on the optimization of production of the monoterpene 1,8-cineole and the sesquiterpene α-bisabolene in R. toruloides. The α-bisabolene titer attained in R. toruloides was found to be proportional to the copy number of the bisabolene synthase (BIS) expression cassette, which in turn influenced the expression level of several native mevalonate pathway genes. The addition of more copies of BIS under a stronger promoter resulted in production of α-bisabolene at 2.2 g/L from lignocellulosic hydrolysate in a 2-L fermenter. Production of 1,8-cineole was found to be limited by availability of the precursor geranylgeranyl pyrophosphate (GPP) and expression of an appropriate GPP synthase increased the monoterpene titer fourfold to 143 mg/L at bench scale. Targeted mevalonate pathway metabolite analysis suggested that 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGR), mevalonate kinase (MK) and phosphomevalonate kinase (PMK) may be pathway bottlenecks are were therefore selected as targets for overexpression. Expression of HMGR, MK, and PMK orthologs and growth in an optimized lignocellulosic hydrolysate medium increased the 1,8-cineole titer an additional tenfold to 1.4 g/L. Expression of the same mevalonate pathway genes did not have as large an impact on α-bisabolene production, although the final titer was higher at 2.6 g/L. Furthermore, mevalonate pathway intermediates accumulated in the mevalonate-engineered strains, suggesting room for further improvement. CONCLUSIONS: This work brings R. toruloides closer to being able to make industrially relevant quantities of terpene from lignocellulosic biomass.
