Abstract
Background
Rhododendron pudingense, firstly discovered in Puding county of Guizhou province in 2020, have adapted to living in rocky fissure habitat, which has important ornamental and economic values. However, the genetic diversity and population structure of this species have been rarely described, which seriously affects the collection and protection of wild germplasm resources.

Results
In the present study, 13 pairs of primers for polymorphic microsatellite were used to investigate the genetic diversity of 65 R. pudingense accessions from six different geographic populations. A total of 254 alleles (Na) were obtained with an average of 19.5 alleles per locus. The average values of polymorphic information content (PIC), observed heterozygosity (Ho), and expected heterozygosity (He) were 0.8826, 0.4501, and 0.8993, respectively, These results indicate that the microsatellite primers adopted demonstrate good polymorphism, and the R. pudingense exhibits a high level of genetic diversity at the species level. The average genetic differentiation coefficient (Fst) was 0.1325, suggested that moderate divergence occurred in R. pudingense populations. The average values of genetic differentiation coefficient and gene flow among populations were 0.1165 and 3.1281, respectively. The analysis of molecular variance (AMOVA) indicated that most of the population differences (88%) were attributed to within-population variation. The PCoA results are consistent with the findings of the UPGMA clustering analysis, supporting the conclusion that the six populations of R. pudingense can be clearly grouped into two separate clusters. Based on Mantel analysis, we speculate that the PD population may have migrated from WM-1 and WM-2. Therefore, it is advised to protect the natural habitat of R. pudingense in situ as much as possible, in order to maximize the preservation of its genetic diversity.

Conclusions
This is the first comprehensive analysis of genetic diversity and population structure of R. pudingense in Guizhou province. The research results revealed the high genetic diversity and moderate population diferentiation in this horticulture plant. This study provide a theoretical basis for the conservation of wild resources of the R. pudingense and lay the foundation for the breeding or cultivation of this new species.

Published: January 2024

Abstract
Background
This meta-analysis was designed to compare the safety and efficiency of remimazolam with those of propofol in patients undergoing gastroscope sedation.

Methods
We searched PubMed, Cochrane Library, Embase, Ovid, Wanfang Database, China National Knowledge Infrastructure, SINOMED, and ClinicalTrials.gov for studies that reported on remimazolam versus propofol for gastroscope sedation from establishment to February 25, 2023. The sedative efficiency and the incidence of adverse events were assessed as outcomes. Version 2 of the Cochrane risk-of-bias assessment tool was used to assess the risk of bias. Review Manager 5.4 and STATA 17 were used to perform all statistical analyses.

Results
A total of 26 randomized controlled trials involving 3,641 patients were included in this meta-analysis. The results showed that remimazolam had a significantly lower incidence of respiratory depression (risk ratio [RR] = 0.40, 95% confidence interval [CI]: 0.28–0.57; p < 0.01, GRADE high), hypoxemia (RR = 0.34, 95% CI: 0.23–0.49; p < 0.01, GRADE high), bradycardia (RR = 0.34, 95% CI: 0.23–0.51; p < 0.01, GRADE high), dizziness (RR = 0.45, 95% CI: 0.31–0.65; p < 0.01, GRADE high), injection site pain (RR = 0.06, 95% CI: 0.03–0.13; p < 0.01, GRADE high), nausea or vomiting (RR = 0.79, 95% CI: 0.62–1.00; p = 0.05, GRADE moderate), and hypotension (RR = 0.36, 95% CI: 0.26–0.48; p < 0.01, GRADE low).

Conclusions
Remimazolam can be used safely in gastroscopic sedation and reduces the incidence of respiratory depression, hypoxemia, bradycardia, injection site pain, and dizziness compared with propofol, and doesn't increase the incidence of nausea and vomiting.

Published: January 2024

Abstract
Background
Management of the enhanced-fibrinolytic type of disseminated intravascular coagulation (DIC) caused by aortic disorders is the two strategies of surgical intervention and medical treatment based on the patient’s age and comorbidities.

Case presentation
An 81-year-old woman with a history of two previous aortic surgeries and chronic heart and renal failure was admitted for uncontrollable subcutaneous hemorrhage. The hemorrhage was caused by the enhanced-fibrinolytic type of disseminated intravascular coagulation (DIC) caused by periprosthetic graft hematoma after aortic replacement for Stanford type A aortic dissection. Open thoracic hemostasis temporarily controlled the subcutaneous hemorrhage, but she was readmitted for the recurrence seven months after discharge. On the second admission, the combination of anticoagulant and antifibrinolytic agents was successful.

Conclusion
Management of the enhanced-fibrinolytic type of DIC caused by aortic disorders is important of a successful combination of surgical and medical therapy tailored the patient’s condition.

Abstract
Introduction
Older adults are increasing in number in both developed and developing countries. However, as the world’s aging population grows, the burden of diseases among older people also increases. Despite this, co-occurring health problems due to physical inactivity in older adults have become a concern, and physical inactivity can be caused by different conditions. As a result, for older adults to have better health outcomes, early diagnosis of physical activity status and prevention of non-communicable diseases are crucial. There is a lack of data on the prevalence and associated factors of physical inactivity among older adults that is scarce in sub-Saharan Africa, particularly in the study area, Ethiopia. Therefore, this study aimed to assess the prevalence and associated factors of physical inactivity among older adults in Gondar town, Northwest Ethiopia, in 2022.

Methods
A community-based cross-sectional study was conducted from April 1st to June 30th, 2022, in Gondar town, Northwest Ethiopia. The data was collected by the Global Physical Activity Questionnaire, Volume 2 through face-to-face interviews among 838 participants. Data were entered into Epinfo version 7.1, then exported and analysed using the Statistical Package of Social Science version 25. A binary logistic regression model was performed to identify factors associated with physical inactivity. The result was considered statistically significant based on an adjusted odds ratio of 95% and a p-value less than 0.05.

Result
The prevalence of physical inactivity was 65.6% (95% CI: 62.1–68.9). Being female (AOR: 3.053, 95% CI:1.487–6.267), age group > = 80 (AOR: 4.082, 95% CI:1.234–13.497), primary school level (AOR: 3.020, 95% CI:1.433–6.367), no formal education (AOR: 8.573, 95% CI:2.843–25.847), unemployed (AOR: 10.273, 95% CI:5.628–18.753), and symptoms of depression (AOR: 7.152, 95% CI: 4.786–17.965) were significantly associated with physical inactivity.

Conclusion
Physical inactivity was relatively high among older adults in Gondar town. Being female, older age, having low levels of education, being unemployed, and having depression symptoms were associated with physical inactivity. We suggest promoting the health benefits of physical activity among females by reducing their burden, older age groups, and unemployed older adults, and avoiding depression among individuals.

Published: January 2024

Abstract
Background
This study aimed to assess the impacts of closed-off measures with different strictness levels (lockdown, partial lockdown and non-lockdown) and geographic proximity to patients with coronavirus disease 2019 (COVID-19) on prenatal depression during an epidemic rebound of COVID-19.

Methods
This was a cross-sectional web-based survey including 880 pregnant women. Depressive symptoms were measured by Self-Rating Depression Scale (SDS) and geographic proximity was calculated using Geographic Information Systems. Linear and logistic regression were used to assess the associations of closed-off measures and geographic proximity with SDS scores and depressive symptoms. Restricted cubic splines were used to model non-linear associations between geographic proximity and depression symptoms.

Results
Compared with those living in non-lockdown areas, women in lockdown areas had higher SDS scores (adjusted β: 3.51, 95% CI: 1.80, 5.21) and greater risk of depressive symptoms (adjusted OR: 4.00, 95% CI: 2.18, 7.35), but evidence for partial lockdown was not obvious. A progressive increase in the risk of depressive symptoms was found with decreasing distance to COVID-19 patients when geographic proximity was <8 kilometers. Compared to those in the 5th quintile of geographic proximity, women in the first, second and third quintiles had at least 6 times higher risk of depressive symptoms.

Conclusions
Pregnant women under strict closed-off management during COVID-19 epidemic have high risk of depression. A specific range around the residences of reported COVID-19 patients should be underlined as potential clustering of high prenatal depression levels. Our findings highlight the importance of enhancing mental health management during the COVID-19 epidemic for pregnant women.

Published: January 2024

Abstract
Background
Hypothyroidism is a major manifestation of autoimmune thyroid diseases (AITD). We previously reported that a low selenium (Se) status was linked to an elevated prevalence of thyroid diseases. We hypothesized that Se status may also influence the restoration of thyroid function. Thus, this study aimed to investigate the factors affecting the recovery of thyroid function in patients with (sub-)clinical hypothyroidism, with a specific focus on Se status.

Methods
We conducted a 6-year prospective cohort study comparing two counties with different Se concentrations. Demographic and disease data were collected from 1,190 individuals (549 Se-adequate and 641 Se-deficient) who completed a follow-up study in 2019. In addition, urinary iodine (I) levels, thyroid function, and serum and nail Se levels were measured. Logistic regression was used to investigate the relationship between Se deficiency and recovery of thyroid function.

Results
Sex and smoking status was similar between the two counties studied. Thyroid function recovery rate was significantly higher in Se-deficient counties (46.0% vs. 30.6%, P = 0.008). In the multivariate analysis, our results show that female sex (odds ratio [OR] (95% confidence interval [CI]) = 1.875 (1.080–3.257), P = 0.026] and increasing age [OR (95%CI) = 1.028(1.007–1.049), P = 0.009] were associated with the recovery rate. Additionally, our study revealed that while Se status was significant in the univariate analysis, this association appeared to disappear in the multivariate analysis.

Conclusions
Female sex and increasing age have unfavorable effects on the recovery of thyroid function in patients over 30 years of age with (sub-) clinical hypothyroidism.

Abstract
Background
Central obesity is considered as a significant health threat to individuals. Scientific research has demonstrated that intra-abdominal fat accumulation is associated with higher metabolic and cardiovascular disease risks independent of Body Mass Index (BMI). This study aimed to evaluate the efficacy and safety of electro-acupuncture in treating central obesity compared with sham acupuncture.

Method
This was a patient-assessor blinded, randomized, sham-controlled clinical trial. One hundred sixty eight participants aged between 18 and 65 years old with BMI ≥ 25 kg/m2 and waist circumference (WC) of men ≥ 90 cm / women ≥ 80 cm were enrolled and allocated to the acupuncture or sham acupuncture group equally. For the acupuncture group, disposable acupuncture needles were inserted into eight body acupoints, including Tianshu (ST-25), Daheng (SP-15), Daimai (GB-26), Qihai (CV-6), Zhongwan (CV-12), Zusanli (ST-36), Fenglong (ST-40), and Sanyinjiao (SP-6) with electrical stimulation. For the control group, Streitberger’s non-invasive acupuncture needles were utilized at the same acupoints with identical stimulation modalities. The treatment duration was 8 weeks with 2 sessions per week and the follow-up period was 8 weeks. The primary outcome was the change in WC before and after the treatment. The secondary outcomes were the changes in hip circumference, waist-to-hip circumference ratio, BMI, and body fat percentage during the treatment and follow-up period.

Results
The acupuncture group displayed a significant change in WC compared to the sham group both treatment and follow-up period (MD = -1.1 cm, 95% CI = -2.8 to 4.1). Significant change in body fat percentage was recorded for both groups after treatment but no significance was observed during the follow-up period (MD = -0.1%, 95% CI = -1.9 to 2.2). The changes in hip circumference were also significant both treatment and follow-up period for the acupuncture group (MD = -2.0 cm, 95% CI = -3.7 to -1.7). Compared with sham acupuncture, the body weight (MD = -1 kg, 95% CI = -3.3 to 5.3), BMI (MD = -0.5, 95% CI = -0.7 to 1.9) also decreased significantly within and between groups. The incidence of adverse events was similar in the two groups.

Conclusion
This study provided evidence that electro-acupuncture could be effective in treating central obesity by reducing WC, hip circumference, body weight, BMI, and waist-to-hip circumference ratio.

A computational model of circRNA-associated diseases based on a graph neural network: prediction and case studies for follow-up experimental validation
Authors: Niu Mengting , Wang Chunyu , Zhang Zhanguo , Zou Quan 
Published: January 2024

AbstractBackgroundCircular RNAs (circRNAs) have been confirmed to play a vital role in the occurrence and development of diseases. Exploring the relationship between circRNAs and diseases is of far-reaching significance for studying etiopathogenesis and treating diseases. To this end, based on the graph Markov neural network algorithm (GMNN) constructed in our previous work GMNN2CD, we further considered the multisource biological data that affects the association between circRNA and disease and developed an updated web server CircDA and based on the human hepatocellular carcinoma (HCC) tissue data to verify the prediction results of CircDA.ResultsCircDA is built on a Tumarkov-based deep learning framework. The algorithm regards biomolecules as nodes and the interactions between molecules as edges, reasonably abstracts multiomics data, and models them as a heterogeneous biomolecular association network, which can reflect the complex relationship between different biomolecules. Case studies using literature data from HCC, cervical, and gastric cancers demonstrate that the CircDA predictor can identify missing associations between known circRNAs and diseases, and using the quantitative real-time PCR (RT-qPCR) experiment of HCC in human tissue samples, it was found that five circRNAs were significantly differentially expressed, which proved that CircDA can predict diseases related to new circRNAs.ConclusionsThis efficient computational prediction and case analysis with sufficient feedback allows us to identify circRNA-associated diseases and disease-associated circRNAs. Our work provides a method to predict circRNA-associated diseases and can provide guidance for the association of diseases with certain circRNAs. For ease of use, an online prediction server (http://server.malab.cn/CircDA) is provided, and the code is open-sourced (https://github.com/nmt315320/CircDA.git) for the convenience of algorithm improvement.

AbstractRecently, the presence of different nanoparticles (NPs) has developed targeting drug delivery in treatment of cancer cell. Targeted drug delivery systems using NPs have shown great promise in improving the efficacy of intracellular uptake as well as local concentration of therapeutics with minimizing side effects. The current study planned to synthesized resveratrol-loaded magnetic niosomes nanoparticles (RSV-MNIONPs) and evaluate their cytotoxicity activity in pancreatic cancer cells. For this aim, magnetic nanoparticles (MNPs) were synthesized and loaded into niosomes (NIOs) by the thin film hydration technique and then characterized via DLS, FT-IR, TEM, SEM and VSM techniques. Moreover, the cytotoxic activity of the RSV-MNIONPs on the Capan-1 cells line was assessed by the MTT test. The distribution number of RSV-MNIONPs was gained about 80 nm and 95 nm with surface charge of − 14.0 mV by SEM and TEM analysis, respectively. RSV loading efficacy in NIOs was about 85%, and the drug releases pattern displayed a sustained discharge with a maximum amount about 35% and 40%, within 4 h in pH = 7.4 and pH = 5.8, respectively. The cytotoxicity of the RSV-MNIONPs in the presence of an external magnetic field is higher than that of the RSV, indicating enhanced cellular uptake in their encapsulated states. Furthermore, RSV loaded MNNPs were found to induce more cell cycle arrest at the G0/G1 checkpoint than free RSV. Compared with RSV-treated cells, the mRNA expression levels of BAX, Bcl2, FAS, P 53, Cyclin D and hTERT, were significantly changed in cells treated with RSV loaded MNNPs. The niosomes NPs approaches have been widely used to attain higher solubility, improved bioavailability, enhanced stability, and control delivery of RSV. Our formulation displayed antitumor activity and can be considered an appropriate carrier with a great potential for future usage in cancer therapy.
Using alone at home: What’s missing in housing-based responses to the overdose crisis?

Published: January 2024

Abstract
Background
Against the backdrop of North America’s overdose crisis, most overdose deaths are occurring in housing environments, largely due to individuals using drugs alone. Overdose deaths in cities remain concentrated in marginal housing environments (e.g., single-room occupancy housing, shelters), which are often the only forms of housing available to urban poor and drug-using communities. This commentary aims to highlight current housing-based overdose prevention interventions and to situate them within the broader environmental contexts of marginal housing. In doing so, we call attention to the need to better understand marginal housing as sites of overdose vulnerability and public health intervention to optimize responses to the overdose crisis.

Harm reduction and overdose prevention in housing
In response to high overdose rates in marginal housing environments several interventions (e.g., housing-based supervised consumption rooms, peer-witnessed injection) have recently been implemented in select jurisdictions. However, even with the growing recognition of marginal housing as a key intervention site, housing-based interventions have yet to be scaled up in a meaningful way. Further, there have been persistent challenges to tailoring these approaches to address dynamics within housing environments. Thus, while it is critical to expand coverage of housing-based interventions across marginal housing environments, these interventions must also attend to the contextual drivers of risks in these settings to best foster enabling environments for harm reduction and maximize impacts.

Conclusion
Emerging housing-focused interventions are designed to address key drivers of overdose risk (e.g., using alone, toxic drug supply). Yet, broader contextual factors (e.g., drug criminalization, housing quality, gender) are equally critical factors that shape how structurally vulnerable people who use drugs navigate and engage with harm reduction interventions. A more comprehensive understanding of these contextual factors within housing environments is needed to inform policy and programmatic interventions that are responsive to the needs of people who use drugs in these settings.
