Abstract
Background
The hair follicle development process is regulated by sophisticated genes and signaling networks, and the hair grows from the hair follicle. The Tianzhu white yak population exhibits differences in hair length, especially on the forehead and shoulder region. However, the genetic mechanism is still unclear. Isoform sequencing (Iso-seq) technology with advantages in long reads sequencing. Hence, we combined the Iso-seq and RNA-seq methods to investigate the transcript complexity and difference between long-haired yak (LHY) and normal-haired yak (NHY).

Results
The hair length measurement result showed a significant difference between LHY and NHY on the forehead and the shoulder (P-value < 0.001). The skin samples from the forehead and the shoulder of LHY and NHY were pooled for isoform sequencing (Iso-seq). We obtained numerous long transcripts, including novel isoforms, long non-coding RNA, alternative splicing events, and alternative polyadenylation events. Combined with RNA-seq data, we performed differential isoforms (DEIs) analysis between LHY and NHY. We found that some hair follicle and skin development-related DEIs, like BMP4, KRT2, IGF2R, and COL1A2 in the forehead skin; BMP1, KRT1, FGF5, COL2A1, and IGFBP5 in the shoulder skin. Enrichment analysis revealed that DEIs in both two comparable groups significantly participated in skin and hair follicle development-related pathways, like ECM-receptor interaction, focal adhesion, and PI3K-Akt signaling pathways. The results indicated that the hair follicle development of Tianzhu white yak may influence the hair length difference. Besides, the protein-protein interaction (PPI) network of DEIs showed COL2A1 and COL3A1 exhibited a high degree of centrality, and these two genes were suggested as potential candidates for the hair length growth of Tianzhu white yak.

Conclusions
The results provided a comprehensive analysis of the transcriptome complexity and identified differential transcripts that enhance our understanding of the molecular mechanisms underlying the variation in hair length growth in Tianzhu white yak.

Abstract
Background
Cardiopulmonary bypass (CPB) results in brain injury, which is primarily caused by inflammation. Ac2-26 protects against ischemic or hemorrhage brain injury. The present study was to explore the effect and mechanism of Ac2-26 on brain injury in CPB rats.

Methods
Forty-eight rats were randomized into sham, CPB, Ac, Ac/AKT1, Ac/GSK3βi and Ac/AKT1/GSK3βa groups. Rats in sham group only received anesthesia and in the other groups received standard CPB surgery. Rats in the sham and CPB groups received saline, and rats in the Ac, Ac/AKT1, Ac/GSK3βi and Ac/AKT1/GSK3βa groups received Ac2-26 immediately after CPB. Rats in the Ac/AKT1, Ac/GSK3βi and Ac/AKT1/GSK3βa groups were injected with shRNA, inhibitor and agonist of GSK3β respectively. The neurological function score, brain edema and histological score were evaluated. The neuronal survival and hippocampal pyroptosis were assessed. The cytokines, activity of NF-κB, S100 calcium-binding protein β(S100β) and neuron-specific enolase (NSE), and oxidative were tested. The NLRP3, cleaved-caspase-1 and cleaved-gadermin D (GSDMD) in the brain were also detected.

Results
Compared to the sham group, all indicators were aggravated in rats that underwent CPB. Compared to the CPB group, Ac2-26 significantly improved neurological scores and brain edema and ameliorated pathological injury. Ac2-26 reduced the local and systemic inflammation, oxidative stress response and promoted neuronal survival. Ac2-26 reduced hippocampal pyroptosis and decreased pyroptotic proteins in brain tissue. The protection of Ac2-26 was notably lessened by shRNA and inhibitor of GSK3β. The agonist of GSK3β recovered the protection of Ac2-26 in presence of shRNA.

Conclusions
Ac2-26 significantly improved neurological function, reduced brain injury via regulating inflammation, oxidative stress response and pyroptosis after CPB. The protective effect of Ac2-26 primarily depended on AKT1/ GSK3β pathway.

Published: May 2024

Abstract
Background
In Flanders, general practitioners (GPs) were among the first ones to collect data regarding COVID-19 cases. Intego is a GPs’ morbidity registry in primary care with data collected from the electronic medical records from a sample of general practices. The Intego database contain elaborate information regarding patient characteristics, such as comorbidities. At the national level, the Belgian Public Health Institute (Sciensano) recorded all test-confirmed COVID-19 cases, but without other patient characteristics.

Methods
Spatio and spatio-temporal analyses were used to analyse the spread of COVID-19 incidence at two levels of spatial aggregation: the municipality and the health sector levels. Our study goal was to compare spatio-temporal modelling results based on the Intego and Sciensano data, in order to see whether the Intego database is capable of detecting epidemiological trends similar to those in the Sciensano data. Comparable results would allow researchers to use these Intego data, and their wealth of patient information, to model COVID-19-related processes.

Results
The two data sources provided comparable results. Being a male decreased the odds of having COVID-19 disease. The odds for the age categories (17,35], (35,65] and (65,110] of being a confirmed COVID-19 case were significantly higher than the odds for the age category [0,17]. In the Intego data, having one of the following comorbidities, i.e., chronic kidney disease, heart and vascular disease, and diabetes, was significantly associated with being a COVID-19 case, increasing the odds of being diagnosed with COVID-19.

Conclusion
We were able to show how an alternative data source, the Intego data, can be used in a pandemic situation. We consider our findings useful for public health officials who plan intervention strategies aimed at monitor and control disease outbreaks such as that of COVID-19.

Abstract
Introduction
Human immunodeficiency virus (HIV) remains a significant health challenge affecting many people including those from sub-Saharan Africa (SSA). Even though HIV can be transmitted through various means, mother-to-child transmission (MTCT) remains the major route of transmission in children under the age of five. This study examined the correlates of knowledge of HIV transmission during pregnancy among reproductive-age women in Ghana.

Methods
Data for this study were obtained from the 2014 Ghana Demographic and Health Survey. The sample consisted of 9,106 women aged 15 to 49 years. We conducted both descriptive and multivariable logistic regression analyses to determine the prevalence and factors associated with knowledge of HIV transmission during pregnancy. The results were presented using frequencies, percentages, and adjusted odds ratios (aOR) with their corresponding 95% confidence intervals (CI).

Results
Approximately, 69.41% of women of reproductive age knew of HIV transmission during pregnancy. Women who had two (aOR = 1.32, 95% CI [1.01, 1.72]) or three (aOR = 1.37, 95% CI [1.07, 1.76]) births were more knowledgeable of HIV transmission during pregnancy. Women who read the newspaper (aOR = 1.56, 95% CI [1.31, 1.86]), listened to the radio (aOR = 1.23, 95% CI [1.05, 1.45]), lived in rural areas (aOR = 1.30, 95% CI [1.09, 1.54]) or ever been tested for HIV (aOR = 1.20, 95% CI [1.05, 1.37]) were more likely to be knowledgeable of HIV transmission during pregnancy than their counterparts in the reference categories. Compared to those in the Western Region, women in the Upper East (aOR = 0.45, 95% CI [0.32, 0.63]), Upper West (aOR = 0.54, 95% CI [0.35, 0.85]), Ashanti (aOR = 0.75, 95% CI [0.58, 0.97]) and Greater Accra Regions (aOR = 0.74, 95% CI [0.56, 0.98]) were less knowledgeable of HIV transmission during pregnancy.

Conclusions
The study highlights a gap in the knowledge of HIV transmission during pregnancy among women in Ghana. Continuous public education is required to educate women on HIV transmission from mothers to their children during pregnancy and how this may be interrupted. Such programs should involve the use of the media and take into consideration the demographic and geographic characteristics highlighted as determinants in this study. This will ultimately contribute to the reduction of MTCT of HIV in Ghana.

Published: May 2024

Abstract
Background
Chronic kidney disease (CKD) is a common postoperative complication in patients who undergo radical nephrectomy for renal tumours. However, the factors influencing long-term renal function require further investigation.

Objective
This study was designed to investigate the trends in renal function changes and risk factors for renal function deterioration in renal tumour patients after radical nephrectomy.

Methods
We monitored changes in renal function before and after surgery for 3 years. The progression of renal function was determined by the progression and degradation of CKD stages. Univariate and multivariate logistic regression analyses were used to analyse the causes of renal function progression.

Results
We analysed the data of 329 patients with renal tumours who underwent radical nephrectomies between January 2013 and December 2018. In this study, 43.7% of patients had postoperative acute kidney injury (AKI), and 48.3% had CKD at advanced stages. Further research revealed that patients’ renal function stabilized 3 months after surgery. Additionally, renal function changes during these 3 months have a substantial impact on the progression of long-term renal function changes in patients.

Conclusion
AKI may be an indicator of short-term postoperative changes in renal function. Renal function tests should be performed in patients with AKI after radical nephrectomy to monitor the progression of functional impairment, particularly within the first 3 months after radical nephrectomy.
Epithelial-to-mesenchymal transition and NF-kB pathways are promoted by a mutant form of DDB2, unable to bind PCNA, in UV-damaged human cells
Authors: Perucca Paola , Bassi Elisabetta , Vetro Martina , Tricarico Anna , Prosperi Ennio , Stivala Lucia Anna , Cazzalini Ornella 
Published: May 2024

Abstract
Background
DNA-Damaged Binding protein 2 (DDB2) is a protein involved in the early step of Nucleotide Excision Repair. Recently, it has been reported that DDB2 is involved in epithelial-to-mesenchymal transition (EMT), key process in tumour invasiveness and metastasis formation. However, its role is not completely known.

Methods
Boyden chamber and cell adhesion assays, and ICELLigence analysis were performed to detect HEK293 adhesion and invasion. Western blotting and gelatine zymography techniques were employed to assess the EMT protein levels and MMP enzymatic activity. Immunofluorescence analysis and pull-down assays facilitated the detection of NF-kB sub-cellular localization and interaction.

Results
We have previously demonstrated that the loss of DDB2-PCNA binding favours genome instability, and increases cell proliferation and motility. Here, we have investigated the phenotypic and molecular EMT-like changes after UV DNA damage, in HEK293 clones stably expressing DDB2Wt protein or a mutant form unable to interact with PCNA (DDB2PCNA−), as well as in HeLa cells transiently expressing the same DDB2 constructs. Cells expressing DDB2PCNA− showed morphological modifications along with a reduced expression of E-cadherin, an increased activity of MMP-9 and an improved ability to migrate, in concomitance with a significant upregulation of EMT-associated Transcription Factors (TFs), whose expression has been reported to favour tumour invasion. We observed a higher expression of c-Myc oncogene, NF-kB, both regulating cell proliferation and metastatic process, as well as ZEB1, a TF significantly associated with tumorigenic potential and cell migratory ability. Interestingly, a novel interaction of DDB2 with NF-kB was detected and found to be increased in cells expressing the DDB2PCNA−, suggesting a direct modulation of NF-kB by DDB2.

Conclusion
These results highlight the role of DDB2-PCNA interaction in counteracting EMT since DDB2PCNA− protein induces in HEK293 transformed cells a gain of function contributing to the acquisition of a more aggressive phenotype.

Abstract
Background
Patients with bipolar disorder (BD) show abnormalities in glucolipid metabolism and reproductive hormone levels, which are of concern in women with BD. This study was dedicated to investigating the glucolipid and reproductive hormone levels of female patients, and to preliminarily investigating their relationships with cognition.

Methods
A total of 58 unmedicated female BD patients, 61 stable-medicated female BD patients, and 63 healthy controls (HC) were recruited in this study. Serum glycolipid indexes and reproductive hormones were measured. Cognitive function was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and the Stroop Color-Word Test (Stroop test).

Results
Patients with BD showed significant cognitive impairment (p < 0.05), which was not affected by medication. Triglycerides (TG), luteinizing hormone (LH), and high-density lipoprotein cholesterol (HDL-c) were altered in stable-medicated BD patients. In addition, regression analysis showed that progesterone (PRGE) and prolactin (PRL) were negatively associated with cognitive performance in stable-medicated BD patients.

Conclusions
Female BD patients may have cognitive deficits and abnormal levels of glycolipids and reproductive hormones. And abnormal levels of glycolipids and reproductive hormones may be associated with cognitive dysfunction in female BD patients.

Authors: Hu Jiayan , Zou Hede , Qiao Xiyun , Wang Yuxi , Lv Mi , Zhang Kunli , Wang Fengyun 
Published: May 2024

Abstract
Background
Oxidative stress is closely related to gut health. Exposures to oxidative stress in one’s diet and lifestyle can be evaluated by the oxidative balance score (OBS). However, the relationship between OBS and intestinal habits is unknown. This study aimed to investigate the relationships between OBS and intestinal habits (chronic diarrhea and chronic constipation) and the underlying mechanisms involved.

Methods
Using data from the National Health and Nutrition Examination Survey (NHANES) database from 2005 to 2010, we included a total of 8065 participants. Twenty dietary and lifestyle factors were selected for the OBS calculates. Chronic constipation and chronic diarrhea were defined using the Bristol stool form scale (BSFS) types 1 and 2 and the BSFS 6 and 7, respectively. Multivariate logistic regression, subgroup analysis, and restricted cubic splines (RCS) analysis were used to evaluate the relationship between OBS and defecation habits. Finally, we used mediation analysis to explore the indirect effects of oxidative stress and inflammatory markers on these associations.

Results
After adjusting for all the covariates, multivariate logistic regression analysis revealed that OBS was negatively correlated with diarrhea (OR = 0.57; 95%CI = 0.39–0.83; P = 0.008)and positively correlated with constipation (OR = 1.75; 95%CI = 1.19–2.25; P = 0.008). The RCS showed a nonlinear relationship between OBS and diarrhea (P for nonlinearity = 0.02) and a linear relationship between OBS and constipation (P for nonlinearity = 0.19). Mediation analysis showed that the C-reactive protein (CRP) concentration and white blood cell (WBC) count mediated the correlation between OBS and diarrhea by 6.28% and 6.53%, respectively (P < 0.05).

Conclusions
OBS is closely related to changes in patients' defecation habits. Oxidative stress and inflammation may play a role in the relationship between the two. This result emphasizes the importance of the public adjusting their lifestyle and dietary habits according to their own situation. However, further prospective studies are needed to analyze the relationship between oxidative stress and changes in defecation habits.
Effects of electronic screen exposure time on hypertensive disorders in pregnancy: a retrospective cohort study
Authors: Tang Shaidi , Liu Yun , Gu Ying , Yang Qianqian , Wang Qian 
Published: May 2024

Abstract
Background
We previously conducted a case-control study and found that exposure to electronic screen before nocturnal sleep was associated with hypertensive disorders in pregnancy (HDP). Hence, we carried out this cohort study aiming to identify the effects of screen exposure time on the incidence rate and severity of HDP.

Methods
A retrospective cohort study was conducted from January 2022 and July 2022 from three hospitals in Wuxi and Changzhou cities. A total of 732 women were recruited and the information included socio-demographic characteristics, screen exposure and outcomes. Generalized estimating equations and binary non-conditional logistic models were applied to multivariate analysis, calculating the odds ratios (ORs) and 95% confidence intervals (CIs) of screen exposure time.

Results
The duration order of total screen time was smartphone > computer > television, while the duration order of screen time before nocturnal sleep was smartphone > television > computer. Multivariate analyses showed that the susceptibility of HDP among women who exposed to television before nocturnal sleep was 81.5% percent higher than those not exposed (P = 0.018, OR[95%CI] = 1.815[1.106–2.981]). In addition, total daily exposure time of television in the third trimester of pregnancy significantly increased the severity of HDP (P = 0.021, OR[95%CI] = 3.641[1.213–10.927]).

Conclusions
Based on this preliminary study, we would suggest that pregnant women do not watch television before nocturnal sleep. While in the third trimester of pregnancy, total exposure time of television should be limited. Investigations from other areas and experimental studies should be conducted to verify the conclusion.
The 8th AJCC classification is inferior to a new neck stage based on intraparotid lymph node in parotid gland cancer
Authors: Han Xiaoxue , Yang Changyu , Tan Xuexin , Li Yuexiao 
Published: May 2024

Abstract
Background
Lymph node (LN) status is an important prognostic factor for parotid gland cancer (PGC). This study aimed to analyze the impact of extranodal extension (ENE) of intraparotid LN and LN metastasis burden on survival in PGC.

Methods
Patients with surgically treated PGC and at least one metastatic cervical LN were retrospectively enrolled. Primary outcome variables were distant metastasis-free survival (DMFS), disease-specific survival (DSS), and overall survival (OS). The impact of ENE and LN metastasis burden was assessed using the Cox model.

Results
A total of 292 patients were included. ENE in cervical or intraparotid LN was not associated with DMFS, DSS, or OS. Intraparotid LN metastasis had a significant impact on prognosis, and the presence of only one metastatic intraparotid LN offered an approximately 1.5-fold risk of distant metastasis. Prognostic models based on the number of positive LNs (1 vs. 2–3 vs. 4+) were superior to the AJCC N stage in terms of DMFS, DSS, and OS.

Conclusions
ENE of cervical or intraparotid LN has a limited effect on the prognosis of PGC, and the number of positive LNs is better than the AJCC N stage in LN status evaluation.
The quality of life and work productivity are affected by the presence of nausea/vomiting in patients taking iron preparations for heavy menstrual bleeding or anemia: a population-based cross-sectional survey in Japan
Authors: Ito Kyoko , Mitobe Yuko , Inoue Ryo , Momoeda Mikio 
Published: May 2024

Abstract
Background
Patients with iron deficiency anemia are treated with iron preparations, but gastrointestinal symptoms such as nausea and vomiting occur frequently. These symptoms may negatively affect the quality of life and work productivity in patients with iron deficiency anemia. This study assessed the impact of nausea and vomiting on the quality of life and work productivity of patients taking iron preparations for heavy menstrual bleeding or anemia.

Methods
An online survey was conducted among patients taking iron preparations for heavy menstrual bleeding or anemia. Demographic data and information about medication use and the health condition were collected. The patients were asked to answer the 5-level EQ-5D version, and work productivity and activity impairment questionnaires. The outcomes were reported by patients in the presences of nausea, vomiting, and nausea or vomiting. The association with the 5-level EQ-5D version utility score for the severity and frequency of the symptoms were also assessed.

Results
A total of 385 patients were enrolled, and 96 were patients with nausea or vomiting, of which 94 were with nausea and 27 were with vomiting. The 5-level EQ-5D version utility scores for the patients with nausea, vomiting, and nausea or vomiting were significantly lower than those of the patients without these symptoms (p < 0.001 for each). The 5-level EQ-5D version utility score was correlated with the severity of nausea and the frequency of vomiting per day (p < 0.001 for each). As for the work productivity and activity impairment, the presenteeism, the overall work impairment, and the activity impairment of the patients with nausea, vomiting, and nausea or vomiting were significantly higher than those without these symptoms (p < 0.001 for each). The absenteeism was slightly higher trend was observed, but not significant.

Conclusion
Patients taking iron preparations who have nausea or vomiting experience a significant burden in terms of poorer quality of life and higher work productivity impairment.

Cardiac organoids do not warrant additional moral scrutiny
Authors: Simons Jannieke N , van der Graaf Rieke , van Delden Johannes JM 
Published: May 2024

AbstractCertain organoid subtypes are particularly sensitive. We explore whether moral intuitions about the heartbeat warrant unique moral consideration for newly advanced contracting cardiac organoids. Despite the heartbeat’s moral significance in organ procurement and abortion discussions, we argue that this significance should not translate into moral implications for cardiac organoids.
