“Here, the Hungarian people will decide how to raise our children”: Populist rhetoric and social categorization in Viktor Orbán’s anti-LGBTQ campaign in Hungary
Authors: Gera Marton
Published: March 2023

This paper analyzes how the Hungarian prime minister Viktor Orbán uses social categorization and populist rhetoric in an anti-LGBTQ campaign. Drawing on social identity theory and the scholarship on populist rhetoric and anti-LGBTQ politics, the article examines 46 interviews, press statements, public speeches, and op-eds by Orbán. Using critical discourse analysis (CDA) and Wodak’s discourse-historical approach, it shows how the prime minister frames LGBTQ communities as an out-group that poses a threat to Hungarian values and way of living. Similar to the issue of immigration and existing anti-LGBTQ frames in other countries, Orbán presents LGBTQ groups within his well-established anti-Western narrative. In addition, he connects LGBTQ communities to other out-groups that have been portrayed as a threat for a long time. The study sheds new light on the linguistic strategies of Orbán and shows how populist rhetoric and social categorization complement each other in a political campaign.
How to increase noninvasive ventilation effectiveness in bulbar amyotrophic lateral sclerosis patients
Authors: Sancho Jesus , Ferrer Santos
Published: March 2023

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease in which the respiratory muscles are also affected, leading to respiratory failure. Bulbar impairment develops in almost all cases during the course of the disease, becoming severe in the late stages of disease. Noninvasive ventilation (NIV) has been shown to increase survival in ALS; however, severe bulbar dysfunction has a negative impact on NIV tolerance and effectiveness. Therefore, certain steps should be taken to improve NIV outcomes in these patients including optimal ventilatory parameters, adequate interface selection, effective respiratory secretion management and control of bulbar symptoms.
Caveolin-1 is involved in fatty infiltration and bone-tendon healing of rotator cuff tear
Authors: Fang Shanhong , You Mengqiang , Wei Jie , Chen Peng
Published: March 2023

Background

Caveolin-1 has been predicted, based on RNA transcriptome sequencing, as a key gene in rotator cuff tear (RCT) and it is related to fatty infiltration. This study aims to elucidate the upstream and downstream mechanism of Caveolin-1 in fatty infiltration and bone-tendon healing after RCT in rat models.

Methods

Differentially expressed genes related to RCT were screened, followed by functional enrichment analysis and protein-protein interaction analysis. GATA6 was overexpressed and Caveolin-1 was knocked down in tendon stem cells (TSCs) to evaluate their effects on the adipogenic differentiation of TSCs. In addition, a RCT rat model was constructed and injected with lentivirus carrying oe-GATA6, oe-Caveolin-1 alone or in combination to assess their roles in fatty infiltration and bone-tendon healing.

Results and conclusion

Caveolin-1 was identified as a key gene involved in the RCT process. In vitro results demonstrated that Caveolin-1 knockdown inhibited adipogenic differentiation of TSCs by activating the cAMP/PKA pathway. GATA6 inhibited the transcription of Caveolin-1 and inhibited its expression, thus suppressing the adipogenic differentiation of TSCs. In vivo data confirmed that GATA6 overexpression activated the cAMP/PKA pathway by downregulating Caveolin-1 and consequently repressed fatty infiltration, promoted bone-tendon healing, improved biomechanical properties and reduced the rupture risk of injured tendon in rats after RCT. Overall, this study provides novel insights into the mechanistic action of Caveolin-1 in the fatty infiltration and bone-tendon healing after RCT.
Changes in life history parameters and transcriptome profile of Serangium japonicum associated with feeding on natural prey (Bemisia tabaci) and alternate host (Corcyra cephalonica eggs)
Authors: Ali Shaukat , Peng Jing , Liang Jian-Feng , Huang Chuyang , Xie Yong-Hui , Wang Xingmin
Published: March 2023

Background

The mass production of natural predators with prolonged shelf life is a prerequisite for their field application as pest control agents. The traditional methods used for the mass production ofSerangium japonicumrely heavily on the consistent supply of natural prey. This study explains the effects ofB. tabaci(natural prey) andC. cephalonicaeggs (alternative food) on life history and transcriptome profile ofS. japanicum.

Methods

This study compares the effects ofB. tabaci(natural prey) andC. cephalonicaeggs (alternative food) on biology, reproduction, and predatory efficacy, and transcriptome profile ofS. japanicum.

Results

This study revealed thatS. japonicumwas able to successfully complete its life cycle while feeding onB. tabaci(natural prey) andC. cephalonicaeggs (alternative food). TheC. cephalonicaeggs fedS. japonicumindividuals had longer developmental period and lower fecundity as compared to those feeding on whitefly but the survival rates (3rd instar nymphs, 4th instar nymphs and pupae) and predatory efficacy ofC. cephalonicaeggs fedS. japonicumindividuals were significantly similar to to those feeding on whitefly.Transcriptome analysis showed that when faced with dietary changes,S. japanicumcould successfully feed onC. cephalonicaeggs by regulating genes related to nutrient transport, metabolism, and detoxification. Moreover,S. japanicumdegraded excess cellular components through ribosomal autophagy and apoptosis, which provided sufficient materials and energy for survival and basic metabolism.

Conclusion

Corcyra cephalonicaeggs can be used as an alternate host for the predator,Serangium japonicum,as the survival rates and predatory efficacy of the predator are similar to those feeding on the natural host (B.tabaci). When faced with dietary changes,S. japanicumcould successfully feed onC. cephalonicaeggs as revealed by upregulation of genes related to nutrient transport, metabolism, and detoxification. These findings are of great significance for studying the functional evolution ofS. japonicumin response to dietary changes.
LncRNA HIF1A-AS2: a potential biomarker for early diagnosis of acute myocardial infarction and predictor of left ventricular dysfunction
Authors: Tayae Eman , Amr Eman , Zaki Amr , Elkaffash Dalal
Published: March 2023

Background

Rapid diagnosis of acute myocardial infarction (AMI) is the subject of many clinical studies as it enables an effective therapy, preventing adverse progression of AMI and increasing survival rates. Recent studies have revealed that specific blood-based long non-coding RNAs (lncRNAs) are deregulated in patients with AMI and serve as promising diagnostic and prognostic tools. The current study aimed to determine the potential role of a hypoxia-responsive lncRNA, hypoxia-inducible factor 1A antisense RNA 2 (HIF1A-AS2), as a biomarker for early diagnosis and predictor of left ventricular dysfunction (LVD).

Methods

This study was carried out on 48 patients with AMI and 50 age-and sex-matched controls. The relative quantification of HIF1A-AS2 expression was done using reverse transcription real‐time polymerase chain reaction.

Results

Compared to the control group, HIF1A-AS2 were significantly higher in MI patients (P < 0.001). Interestingly, patients presenting within 3 h of chest pain onset had elevated levels of HIF1A‐AS2 as compared to patients with late presentation. The ROC curve was constructed to assess HIF1A-AS2 as an early marker. It demonstrated higher sensitivity (94%) and specificity (86%). Moreover, the multivariate regression analysis revealed that HIF1A‐AS2 was significantly associated with LVD in the patient group after 6 months follow up (p = 0.018).

Conclusion

Our study suggests that HIF1A‐AS2 may be a potential early diagnostic biomarker of AMI with high sensitivity. In addition, it might have a promising role as a predictor of left ventricular dysfunction.
Syncope as the initial symptom in a patient with nasopharyngeal carcinoma: a case report
Authors: Zhang Lin-lin , Wang Lei , Ge Jie , Sun Shi-kun
Published: March 2023

Background

A high prevalence of nasopharyngeal carcinoma (NPC) has been found in China, but it rarely occurs with syncope. Studies have demonstrated that syncope due to NPC may be related to carotid sinus syndrome, glossopharyngeal irritation, and parapharyngeal and retropharyngeal space lesions. Such patients require evaluation by nasopharyngoscopy and head magnetic resonance imaging/computed tomography. There is no known single effective treatment for these patients. Various interventions may be considered in an effort to relieve syncope, including vasoconstrictive drugs, cardiac pacemaker implantation, radiotherapy and chemotherapy, and surgical resection.

Case presentation

This case report describes a 56-year-old man who developed recurrent syncope with atrial fibrillation, a long RR interval, and hypotension. A single chamber pacemaker was fitted, but it failed to relieve the symptom. Cranial magnetic resonance imaging and pathological tests led to a final diagnosis of NPC. After six courses of chemotherapy and 35 sessions of radiotherapy, the patient became asymptomatic. However, he died from a massive uncontrolled hemorrhage in the nasopharynx two years later.

Conclusions

This case brings attention to the fact that syncope can be a symptom of NPC. Due to the insidiously malignant nature of this cancer, when a patient presents with syncope, clinicians should bear in mind this connection, albeit a rare one. There are at least two ways of treating NPC-associated syncope, but there is disagreement about which is the most effective.

Authors: Liu Xiaoyan , Sun Yan , Zhang Xuyan , Liu Ping , Zhang Kan , Yu Lihua , Su Yujie , Yuan Yuan , Ke Qing , Peng Guoping
Published: March 2023

Background

Rapidly progressive dementia (RPD) is a syndrome originating from various diseases. Recent advances have allowed a better understanding of its categories and spectrum; however, it remains challenging to make an accurate differential diagnosis and prognosis prediction.

Methods

This study was a retrospective evaluation of all participants admitted to the neurology department of a single center in China from January 2015 to December 2019. The screened patients met the RPD criteria and their characteristics were collected to explore a diagnostic pattern of RPD. In addition, outcomes of RPD were evaluated with the Glasgow Outcome Scale (GOS), activities of daily living scale (ADL), and simplified Mini-Mental State Examination (MMSE), and different prognostic analysis methods were performed to determine the prognostic factors of RPD.

Results

A total of 149 RPD patients among 15,731 inpatients were identified with an average MMSE value of 13.0 ± 4.6 at baseline. Etiological epidemiology revealed infectious, neurodegenerative and toxic/metabolic diseases as the three largest groups, accounting for 26.2%, 20.8% and 16.8% of all cases, respectively. In particular, prevalence rates of Creutzfeldt–Jakob disease (13.4%), Alzheimer’s disease (11.4%), carbon monoxide poisoning (8.1%), neurosyphilis (5.4%) and dementia with Lewy bodies (5.4%) were highest in this series. A recommended diagnostic framework for RPD etiology was thus established. Follow-up evaluations showed a negative correlation between age and GOS scores (r=-0.421, P < 0.001), as well as age and simplified MMSE scores (rs =- 0.393, P < 0.001), and a positive correlation between age and ADL scores (rs =0.503, P < 0.001), and significantly different GOS, ADL and simplified MMSE scores across various etiologies (P = 0.003; F = 9.463, P < 0.001; F = 6.117, P < 0.001).

Conclusion

Infectious, neurodegenerative and toxic-metabolic entities were the most common RPD categories, and establishing a practical approach to RPD etiology would allow better disease management.
Effectiveness of the secondary distribution of HIV self-testing with and without monetary incentives among men who have sex with men living with HIV in China: study protocol for a randomized controlled trial
Authors: Hu Siyue , Lu Ying , He Xi , Zhou Yi , Wu Dan , Tucker Joseph D. , Yang Bin , Tang Weiming
Published: March 2023

Background

The HIV epidemic is still expanding among men who have sex with men (MSM) in China, but HIV testing rates remain suboptimal. Network-based interventions, such as secondary distribution, have shown promise to expand HIV self-testing (HIVST) among partners of MSM living with HIV (MLWH) but have not been widely implemented. Monetary incentives could enhance the secondary distribution of HIVST in some settings. We will conduct a randomized controlled trial to examine the effectiveness of monetary incentives in expanding the secondary distribution of HIVST among MLWH in China.

Methods

We will recruit 200 eligible participants at three antiretroviral therapy (ART) clinics in China. Participants are eligible if they are 18 years of age or over, assigned as male at birth, have had anal sex with men, are living with HIV, are willing to apply for the HIVST kit at ART clinics, and are willing to provide personal contact information for follow-up. Eligible participants will be randomly assigned in a 1:1 ratio to one of two groups: standard secondary distribution group and secondary distribution group with monetary incentives. Participants (defined as “index”) will distribute the HIVST kits to members of their social network (defined as “alter”) and will be required to complete a baseline survey and a 3-month follow-up survey. All alters will be encouraged to report their testing results by taking photos of used kits and completing an online survey. The primary study outcomes will compare the mean number of alters and newly-tested alters motivated by each index participant in each group. Secondary study outcomes will include the mean number of alters who tested positive, the cost per person tested, and the cost per HIV diagnosed for each group.

Discussion

Few studies have evaluated interventions to enhance the implementation of secondary distribution. Our study will provide information on the effectiveness of monetary incentives in expanding HIVST secondary distribution among MLWH. The findings of this trial will contribute to implementing HIVST secondary distribution services among MLWH in China and facilitating HIV case identifications.

Muscle quality index is associated with trouble sleeping: a cross-sectional population based study
Authors: You Yanwei , Chen Yuquan , Zhang Qi , Yan Ning , Ning Yi , Cao Qiang
Published: March 2023

Background

Trouble sleeping is one of the major health issues nowadays. Current evidence on the correlation between muscle quality and trouble sleeping is limited.

Methods

A cross-sectional study design was applied and participants aged from 18 to 60 years in the National Health and Nutrition Examination Survey (NHANES) 2011–2014 was used for analysis. Muscle quality index (MQI) was quantitatively calculated as handgrip strength (HGS, kg) sum/ arm and appendicular skeletal muscle mass (ASM, kg) by using the sum of the non-dominant hand and dominant hand. Sleeping data was obtained by interviews and self-reported by individuals. The main analyses utilized weighted multivariable logistic regression models according to the complex multi-stage sampling design of NHANES. Restricted cubic spline model was applied to explore the non-linear relationship between MQI and trouble sleeping. Moreover, subgroup analyses concerning sociodemographic and lifestyle factors were conducted in this study.

Results

5143 participants were finally included in. In the fully adjusted model, an increased level of MQI was significantly associated with a lower odds ratio of trouble sleeping, with OR = 0.765, 95% CI: (0.652,0.896), p = 0.011. Restricted cubic spline showed a non-linear association between MQI and trouble sleeping. However, it seemed that the prevalence of trouble sleeping decreased with increasing MQI until it reached 2.362, after which the odds ratio of trouble sleeping reached a plateau. Subgroup analyses further confirmed that the negative association between the MQI and trouble sleeping was consistent and robust across groups.

Conclusion

Overall, this study revealed that MQI can be used as a reliable predictor in odds ratio of trouble sleeping. Maintaining a certain level of muscle mass would be beneficial to sleep health. However, this was a cross-sectional study, and causal inference between MQI and trouble sleeping was worthy of further exploration.
A real-world analysis of hybrid CDA and ACDF compared to multilevel ACDF
Authors: Kim Kee D , Coric Domagoj , Khachatryan Armen , Brady Brenna L , Lillehaugen Timothy , McCormack Mike , Dolman William B , Ditto Richard
Published: March 2023

Background

Multilevel anterior cervical discectomy and fusion (mACDF) is the gold standard for multilevel spinal disease; although safe and effective, mACDF can limit regular spinal motion and contribute to adjacent segment disease (ASD). Hybrid surgery, composed of ACDF and cervical disc arthroplasty, has the potential to reduce ASD by retaining spinal mobility. This study examined the safety of hybrid surgery by utilizing administrative claims data to compare real-world rates of subsequent surgery and post-procedural hospitalization within populations of patients undergoing hybrid surgery versus mACDF for multilevel spinal disease.

Methods

This observational, retrospective analysis used the MarketScan Commercial and Medicare Database from July 2013 through June 2020. Propensity score matched cohorts of patients who received hybrid surgery or mACDF were established based on the presence of spinal surgery procedure codes in the claims data and followed over a variable post-period. Rates of subsequent surgery and post-procedural hospitalization (30- and 90-day) were compared between hybrid surgery and mACDF cohorts.

Results

A total of 430 hybrid surgery patients and 2,136 mACDF patients qualified for the study; average follow-up was approximately 2 years. Similar rates of subsequent surgery (Hybrid: 1.9 surgeries/100 patient-years; mACDF: 1.8 surgeries/100 patient-years) were observed for the two cohorts. Hospitalization rates were also similar across cohorts at 30 days post-procedure (Hybrid: 0.67% hospitalized/patient-year; mACDF: 0.87% hospitalized/patient-year). At 90 days post-procedure, hybrid surgery patients had slightly lower rates of hospitalization compared to mACDF patients (0.23% versus 0.42% hospitalized/patient-year; p < 0.05).

Conclusions

Findings of this real-world, retrospective cohort study confirm prior reports indicating that hybrid surgery is a safe and effective intervention for multilevel spinal disease which demonstrates non-inferiority in relation to the current gold standard mACDF. The use of administrative claims data in this analysis provides a unique perspective allowing the inclusion of a larger, more generalizable population has historically been reported on in small cohort studies.

Authors: Kistemaker K.R.J. , de Graeff A. , Crul M. , de Klerk G. , van de Ven P.M. , van der Meulen M.P. , van Zuylen L. , Steegers M.A.H.
Published: March 2023

Background

Opioid-induced constipation (OIC) is a common symptom in cancer patients treated with opioids with a prevalence of up to 59%. International guidelines recommend standard laxatives such as macrogol/electrolytes and magnesium hydroxide to prevent OIC, although evidence from randomized controlled trials is largely lacking. The aim of our study is to compare magnesium hydroxide with macrogol /electrolytes in the prevention of OIC in patients with incurable cancer and to compare side-effects, tolerability and cost-effectiveness.

Methods

Our study is an open-label, randomized, multicenter study to examine if magnesium hydroxide is non-inferior to macrogol/electrolytes in the prevention of OIC. In total, 330 patients with incurable cancer, starting with opioids for pain management, will be randomized to treatment with either macrogol/electrolytes or magnesium hydroxide. The primary outcome measure is the proportion of patients with a score of < 30 on the Bowel Function Index (BFI), measured on day 14.

The Rome IV criteria for constipation, side effects of and satisfaction with laxatives, pain scores, quality of life (using the EQ-5D-5L), daily use of laxatives and escape medication, and cost-effectiveness will also be assessed.

Discussion

In this study we aim to examine if magnesium hydroxide is non-inferior to macrogol/electrolytes in the prevention of OIC. The outcome of our study will contribute to prevention of OIC and scientific evidence of guidelines on (opioid-induced) constipation.

Ethical considerations of the vaccine development process and vaccination: a scoping review
Authors: Jalilian Habib , Amraei Mahdi , Javanshir Elnaz , Jamebozorgi Khosro , Faraji-Khiavi Farzad
Published: March 2023

Background

Various vaccines have been developed and distributed worldwide to control and cope with COVID-19 disease. To ensure vaccines benefit the global community, the ethical principles of beneficence, justice, non-maleficence, and autonomy should be examined and adhered to in the process of development, distribution, and implementation. This study, therefore, aimed to examine ethical considerations of vaccine development and vaccination processes.

Methods

A scoping review of the literature was conducted based on the Arkesy and O’Malley protocol to identify eligible studies published until November 2021. We searched Web of Science, PubMed, Scopus, and SciELO databases. The search was conducted using combinations of Medical Subject Heading (MeSH) search terms and keywords for Ethics, COVID-19, and vaccines in abstract, keywords, and title fields to retrieve potentially relevant publications. We included any study that reported one of the four principles of medical ethics: autonomy, justice, non-maleficence, and beneficence in the COVID-19 vaccine development and distribution and implementation of vaccinations. Letters, notes, protocols, and brief communications were excluded. In addition, we searched gray literature to include relevant studies (ProQuest database, conferences, and reports). Data were analyzed using framework analysis.

Results

In total, 43 studies were included. Ethical considerations concluded two themes: (1) production and (2) distribution and vaccination. The production process consisted of 16 codes and 4 main Categories, distribution and vaccination process consisted of 12 codes and 4 main Categories. Moreover, the ethical considerations of special groups were divided into four main groups: health care workers (HCWs) (five codes), children and adolescents (five codes), the elderly (one code), and ethnic and racial minorities (three codes).

Conclusion

Due to the externalities of pandemics and the public and social benefits and harms of vaccination, it is not feasible to adhere to all four principles of medical ethics simultaneously and perfectly. This issue confronts individuals and policymakers with several moral dilemmas. It seems that decision-making based on the balance between social benefit and social harm is a better criterion in this regard, and the final decision should be made based on maximizing the public benefit and minimizing the public harm.

Published: March 2023

Background

The identification of effective dementia prevention strategies is a major public health priority, due to the enormous and growing societal cost of this condition. Consumption of a Mediterranean diet (MedDiet) has been proposed to reduce dementia risk. However, current evidence is inconclusive and is typically derived from small cohorts with limited dementia cases. Additionally, few studies have explored the interaction between diet and genetic risk of dementia.

Methods

We used Cox proportional hazard regression models to explore the associations between MedDiet adherence, defined using two different scores (Mediterranean Diet Adherence Screener [MEDAS] continuous and Mediterranean diet Pyramid [PYRAMID] scores), and incident all-cause dementia risk in 60,298 participants from UK Biobank, followed for an average 9.1 years. The interaction between diet and polygenic risk for dementia was also tested.

Results

Higher MedDiet adherence was associated with lower dementia risk (MEDAS continuous: HR = 0.77, 95% CI = 0.65–0.91; PYRAMID: HR = 0.86, 95% CI = 0.73–1.02 for highest versus lowest tertiles). There was no significant interaction between MedDiet adherence defined by the MEDAS continuous and PYRAMID scores and polygenic risk for dementia.

Conclusions

Higher adherence to a MedDiet was associated with lower dementia risk, independent of genetic risk, underlining the importance of diet in dementia prevention interventions.
Differential expression of pyroptosis-related genes in the hippocampus of patients with Alzheimer’s disease
Authors: Xia Pengcheng , Ma Huijun , Chen Jing , Liu Yingchao , Cui Xiaolin , Wang Cuicui , Zong Shuai , Wang Le , Liu Yun , Lu Zhiming
Published: March 2023

Background

Alzheimer’s disease (AD) is a progressive, neurodegenerative disorder with insidious onset. Some scholars believe that there is a close relationship between pyroptosis and AD. However, studies with evidence supporting this relationship are lacking.

Materials and methods

The microarray data of AD were retrieved from the Gene Expression Omnibus (GEO) database with the datasets merged using the R package inSilicoMerging. R software package Limma was used to perform the differential expression analysis to identify the differentially expressed genes (DEGs). We further performed the enrichment analyses of the DEGs based on Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) databases to identify the metabolic pathways with a significant difference. The Gene Set Enrichment Analysis (GSEA) was applied to identify the significant pathways. The protein-protein interaction (PPI) network was constructed based on the STRING database with the hub genes identified. Quantitative real-time PCR (qRT-PCR) analyses based on HT22 cells were performed to validate the findings based on the microarray analysis. Gene expression correlation heatmaps were generated to evaluate the relationships among the genes.

Results

A new dataset was derived by merging 4 microarray datasets in the hippocampus of AD patients in the GEO database. Differential gene expression analysis yielded a volcano plot of a total of 20 DEGs (14 up-regulated and 6 down-regulated). GO analysis revealed a group of GO terms with a significant difference, e.g., cytoplasmic vesicle membrane, vesicle membrane, and monocyte chemotaxis. KEGG analysis detected the metabolic pathways with a significant difference, e.g., Rheumatoid arthritis and Fluid shear stress and atherosclerosis. The results of the Gene Set Enrichment Analysis of the microarray data showed that gene set ALZHEIMER_DISEASE and the gene set PYROPTOSIS were both up-regulated. PPI network showed that pyroptosis-related genes were divided into two groups. In the Aβ-induced HT22 cell model, three genes (i.e., BAX, IL18, and CYCS) were revealed with significant differences. Gene expression correlation heatmaps revealed strong correlations between pyroptotic genes and AD-related genes.

Conclusion

The pyroptosis-related genes BAX, IL18, and CYCS were significantly different between AD patients and normal controls.
Identification of ferroptosis related biomarkers and immune infiltration in Parkinson’s disease by integrated bioinformatic analysis
Authors: Xing Na , Dong Ziye , Wu Qiaoli , Zhang Yufeng , Kan Pengcheng , Han Yuan , Cheng Xiuli , Wang Yaru , Zhang Biao
Published: March 2023

Background

Increasing evidence has indicated that ferroptosis engages in the progression of Parkinson’s disease (PD). This study aimed to explore the role of ferroptosis-related genes (FRGs), immune infiltration and immune checkpoint genes (ICGs) in the pathogenesis and development of PD.

Methods

The microarray data of PD patients and healthy controls (HC) from the Gene Expression Omnibus (GEO) database was downloaded. Weighted gene co-expression network analysis (WGCNA) was processed to identify the significant modules related to PD in the GSE18838 dataset. Machine learning algorithms were used to screen the candidate biomarkers based on the intersect between WGCNA, FRGs and differentially expressed genes. Enrichment analysis of GSVA, GSEA, GO, KEGG, and immune infiltration, group comparison of ICGs were also performed. Next, candidate biomarkers were validated in clinical samples by ELISA and receiver operating characteristic curve (ROC) was used to assess diagnose ability.

Results

In this study, FRGs had correlations with ICGs, immune infiltration. Then, plasma levels of LPIN1 in PD was significantly lower than that in healthy controls, while the expression of TNFAIP3 was higher in PD in comparison with HC. ROC curves showed that the area under curve (AUC) of the LPIN1 and TNFAIP3 combination was 0.833 (95% CI: 0.750–0.916). Moreover, each biomarker alone could discriminate the PD from HC (LPIN1: AUC = 0.754, 95% CI: 0.659–0.849; TNFAIP3: AUC = 0.754, 95% CI: 0.660–0.849). For detection of early PD from HC, the model of combination maintained diagnostic accuracy with an AUC of 0.831 (95% CI: 0.734–0.927), LPIN1 also performed well in distinguishing the early PD from HC (AUC = 0.817, 95% CI: 0.717–0.917). However, the diagnostic efficacy was relatively poor in distinguishing the early from middle-advanced PD patients.

Conclusion

The combination model composed of LPIN1 and TNFAIP3, and each biomarker may serve as an efficient tool for distinguishing PD from HC.
Quality of total hip arthroplasty health care based on four years of patient-reported outcomes in the Netherlands
Authors: Pronk Yvette , van der Weegen Walter , Schreurs Berend Willem , Pilot Peter
Published: March 2023

Background

Joint arthroplasty registries have incorporated patient-reported outcomes (PROs) to evaluate outcomes from a patients’ perspective to improve total hip arthroplasty (THA). To draw valid conclusions on PROs, a minimum response rate (RR) of 60% is advised. This study investigated (1) if the quality of THA health care based on PROs improved over the years in the Netherlands, (2) if RRs improved over the years, and (3) difference in PROs over the years in hospitals with RR ≥ 60% compared to RR < 60%.

Methods

Longitudinal study with publicly available datasets from 2016 to 2019. Primary outcome was increase/decrease in PRO change scores including 95%CI ranges over the years between preoperatively and 3 months postoperatively (pre-3 m), and 12 months postoperatively (pre-12 m). Improved quality of health care was arbitrary defined as when ≥ 3 of 4 included scores or ranges were statistically significant improved. Secondary outcome was increase/decrease in RRs over the years. Subgroups RR ≥ 60% and RR < 60% were compared.

Results

Hospitals (%) collecting THA PROs increased from 78 to 92%. EQ VAS change score increased over the years, and 95%CI ranges of EQ VAS, EQ-5D descriptive system and NRS pain during activity decreased over the years at pre-3 m (p < 0.05). All THA pre-12 m PRO change scores and 95%CI ranges remained equal (p > 0.05). Pre-3 m RR remained equal (around 43%, p = 0.107) and pre-12 m RR decreased 9% (49% to 40%, p = 0.008). Pre-3 m subgroup RR ≥ 60% was too small to analyse (5%). No difference was found between pre-12 m subgroups (RR ≥ 60% = 16%), p > 0.05).

Conclusions

Quality of THA health care based on PROs seems equal in the Netherlands between 2016 and 2019. Although more hospitals participated in PRO collection, low RRs with large IQRs are observed and only 16% of the hospitals achieved the advised RR ≥ 60%. Multiple recommendations are provided to improve PRO collection and use.
Apigenin reduces the suppressive effect of exosomes derived from irritable bowel syndrome patients on the autophagy of human colon epithelial cells by promoting ATG14
Authors: Fu Rui , Liu Saiyue , Zhu Mingjin , Zhu Jiajie , Chen Mingxian
Published: March 2023

Background

Inflammatory bowel disease (IBS) is a chronic disorder of the gastrointestinal tract. Exosomes have been involved in various pathological processes including IBS. Apigenin has been reported to suppress inflammatory bowel disease (IBS). However, the regulatory roles of exosomes derived from IBS patients (IBS-exos) on human colon epithelial cells are still unclear.

Methods

Exosomes were collected from IBS patients (IBS-exos) and co-cultured with CACO-2 cells. Apigenin was used to treat IBS-exos-treated CACO-2 cells. By exploring the public data bank, we figured out the regulators control the autophagy of CACO-2 cells.

Results

Administration of apigenin dose-dependently abolished the inhibitory effect of IBS-exo on the autophagy of CACO-2 cells. A mechanistic study showed that miR-148b-3p bound to 3′UTR to suppress ATG14 and decrease autophagy. Moreover, results suggested that ATG14 overexpression promoted the autophagy of CACO-2 cells in the presence of miR-148b-3p mimic.

Conclusion

The current study showed that apigenin dose-dependently abolished the inhibitory effect of IBS-exo on CACO-2 cell autophagy by regulating miR-148b-3p/ATG14 signaling.

The COVID-19 pandemic led to worldwide health service disruptions, due mainly to insufficient staff availability. To gain insight into policy responses and engage with policy-makers, the World Health Organization (WHO) developed a global approach to assess and measure the impact of COVID-19 on the health workforce. As part of this, WHO, together with the Pan American Health Organization (PAHO), supported an impact analysis of COVID-19 on health workers and policy responses, through country case studies in Latin America and the Caribbean (LAC).

Methods

We sought to identify lessons learned from policies on human resources for health (HRH) during health emergencies, to improve HRH readiness. First, we performed a rapid literature review for information-gathering. Second, we used the WHO interim guidance and impact measurement framework for COVID-19 and HRH to systematically organize that information. Finally, we used the Health Labour Market Framework to guide the content analysis on COVID-19 response in eight LAC countries and identify lessons learned to improve HRH readiness.

Results

Planning and implementing the COVID-19 response required strengthening HRH governance and HRH data and information systems. The results suggest two main aspects for HRH governance crucial to enabling an agile response: (1) aligning objectives among ministries to define and produce regulation and policy actions; and (2) agreeing on the strategy for HRH management between the public and private sectors, and between central and local governments. We identified three areas for improvement: (a) HRH information systems; (b) methodologies to estimate HRH needs; and (c) teams to analyse information for decision-making. Three key actions were identified during countries monitored, reviewed, and updated their response stages: (i) strengthening response through primary health care; (ii); planning HRH needs to implement the vaccination plan; and (iii) securing long-term HRH availability.

Conclusion

Countries coordinated and articulated with different stakeholders to align objectives, allocate resources, and agree on policy actions to implement the COVID-19 response. Data and information for HRH preparedness and implementation were key in enabling an agile COVID-19 response and are key areas to explore for improved pandemic preparedness.

Background

Missed nursing care undermines nursing standards of care and minimising this phenomenon is crucial to maintaining adequate patient safety and the quality of patient care. The concept is a neglected aspect of human resource for health thinking, and it remains understudied in low-income and middle-income country (LMIC) settings which have 90% of the global nursing workforce shortages. Our objective in this review was to document the prevalence of missed nursing care in LMIC, identify the categories of nursing care that are most missed and summarise the reasons for this.

Methods

We conducted a systematic review searching Medline, Embase, Global Health, WHO Global index medicus and CINAHL from their inception up until August 2021. Publications were included if they were conducted in an LMIC and reported on any combination of categories, reasons and factors associated with missed nursing care within in-patient settings. We assessed the quality of studies using the Newcastle Ottawa Scale.

Results

Thirty-one studies met our inclusion criteria. These studies were mainly cross-sectional, from upper middle-income settings and mostly relied on nurses’ self-report of missed nursing care. The measurement tools used, and their reporting were inconsistent across the literature. Nursing care most frequently missed were non-clinical nursing activities including those of comfort and communication. Inadequate personnel numbers were the most important reasons given for missed care.

Conclusions

Missed nursing care is reported for all key nursing task areas threatening care quality and safety. Data suggest nurses prioritise technical activities with more non-clinical activities missed, this undermines holistic nursing care. Improving staffing levels seems a key intervention potentially including sharing of less skilled activities. More research on missed nursing care and interventions to tackle it to improve quality and safety is needed in LMIC.

Published: March 2023

Background

Weather is a potentially important influence on how time is allocated to sleep, sedentary behaviour and physical activity across the 24-h day. Extremes of weather (very hot, cold, windy or wet) can create undesirable, unsafe outdoor environments for exercise or active transport, impact the comfort of sleeping environments, and increase time indoors. This 13-month prospective cohort study explored associations between weather and 24-h movement behaviour patterns.

Methods

Three hundred sixty-eight adults (mean age 40.2 years, SD 5.9, 56.8% female) from Adelaide, Australia, wore Fitbit Charge 3 activity trackers 24 h a day for 13 months with minute-by-minute data on sleep, sedentary behaviour, light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) collected remotely. Daily weather data included temperature, rainfall, wind, cloud and sunshine. Multi-level mixed-effects linear regression analyses (one model per outcome) were used.

Results

Ninety thousand eight hundred one days of data were analysed. Sleep was negatively associated with minimum temperature (-12 min/day change across minimum temperature range of 31.2 °C, p = 0.001). Sedentary behaviour was positively associated with minimum temperature (+ 12 min/day, range = 31.2 oC, p = 0.006) and wind speed (+ 10 min/day, range = 36.7 km/h, p< 0.001), and negatively associated with sunshine (-17 min/day, range = 13.9 h, p < 0.001). LPA was positively associated with minimum temperature (+ 11 min/day, range = 31.2 °C, p = 0.002), cloud cover (+ 4 min/day, range = 8 eighths, p = 0.008) and sunshine (+ 17 min/day, range = 13.9 h, p < 0.001), and negatively associated with wind speed (-8 min/day, range = 36.7 km/h, p < 0.001). MVPA was positively associated with sunshine (+ 3 min/day, range = 13.9 h, p < 0.001) and negatively associated with minimum temperature (-13 min/day, range = 31.2 oC, p < 0.001), rainfall (-3 min/day, range = 33.2 mm, p = 0.006) and wind speed (-4 min/day, range = 36.7 km/h, p < 0.001). For maximum temperature, a significant (p < 0.05) curvilinear association was observed with sleep (half-U) and physical activity (inverted-U), where the decrease in sleep duration appeared to slow around 23 °C, LPA peaked at 31 oC and MVPA at 27 °C.

Conclusions

Generally, adults tended to be less active and more sedentary during extremes of weather and sleep less as temperatures rise. These findings have the potential to inform the timing and content of positive movement behaviour messaging and interventions.

Trial registration

The study was prospectively registered on the Australian New Zealand Clinical Trial Registry (Trial ID: ACTRN12619001430123).
Atf4 regulates angiogenic differences between alveolar bone and long bone macrophages by regulating M1 polarization, based on single-cell RNA sequencing, RNA-seq and ATAC-seq analysis

In the repair of maxillofacial bone defects, autogenous craniofacial bone can often provide superior clinical results over long bone grafts. Most current studies have focused on the osteogenic differences between alveolar bone marrow (ABM) and long bone marrow (LBM), however, studies about the angiogenic differences between the two are currently lacking. We downloaded single-cell RNA sequencing (scRNA-seq) of mouse ABM and LBM respectively from the public database, and the data were processed by using Seurat package. CellphoneDB2 results showed that macrophages had the strongest interaction with mesenchymal stem cells (MSCs) and endothelial cells (ECs). ELISA results confirmed that ABM macrophages secreted a higher level of vascular endothelial growth factor A (Vegfa) compared to LBM macrophages, which further promoted angiogenesis of ECs and MSCs. Using SCENIC package, six key transcription factors (TFs) were identified to regulate the difference between ABM and LBM macrophages, and activating transcription factor 4 (Atf4) was confirmed to be more expressed in ABM macrophages by polymerase chain reaction (PCR) and western blot (WB), with predicted target genes including Vegfa. Besides, the result of scRNA-seq implied ABM macrophages more in M1 status than LBM macrophages, which was confirmed by the following experiments. From the results of another assay for transposase accessible chromatin sequencing (ATAC-seq) and RNA-seq about M1 macrophages, Atf4 was also confirmed to regulate the M1 polarization. So, we suspected that Atf4 regulated the different expression of Vegfa between ABM and LBM macrophages by activating M1 polarization. After knocking down Atf4, the expression of M1 polarization markers and Vegfa were downregulated and vasculogenic differences were eliminated, which were subsequently reversed by the addition of LPS/IFN-γ. Our study might provide a new idea to improve the success rate of autologous bone grafting and treatment of oral diseases.

Authors: D’Aurizio Giulia , Di Stefano Ramona , Socci Valentina , Rossi Alessandro , Barlattani Tommaso , Pacitti Francesca , Rossi Rodolfo
Published: March 2023

Background

The emotional regulation process plays a pivotal role in daily-life functioning, modulating goal-directed and adaptive behavior. Conversely, altering this cognitive function can disrupt self-regulation and bring emotional dysregulation. Emotional instability could represent a core characteristic of BPD, also modulating the BPD symptom's onset. This systematic review aims to summarize the existing literature reporting the role of emotional instability in BPD to better define the role of the impairment of the emotional processes in the onset of the cognitive and behavioral symptoms of this complex mental disorder.

Methods

MEDLINE, Scopus and Web of Science were independently searched for relevant studies. Eligible studies had to be identifiable through database searching, published and accessible. This systematic review was conducted according to PRISMA guidelines. The search period was from 2012 to 14 September 2022.

Results

A pool of 120 studies was identified, out of which 11 met the selection criteria and were included. Overall, the studies confirm a relationship between emotional instability and borderline personality disorder.

Conclusions

The evidences retrieved seem to point out the role of the emotional impairment not only in worsening of the disorder, but could also be one of the risk factors for its onset.
Clinical application of MR-Linac in tumor radiotherapy: a systematic review
Authors: Liu Xin , Li Zhenjiang , Yin Yong
Published: March 2023

Recent years have seen both a fresh knowledge of cancer and impressive advancements in its treatment. However, the clinical treatment paradigm of cancer is still difficult to implement in the twenty-first century due to the rise in its prevalence. Radiotherapy (RT) is a crucial component of cancer treatment that is helpful for almost all cancer types. The accuracy of RT dosage delivery is increasing as a result of the quick development of computer and imaging technology. The use of image-guided radiation (IGRT) has improved cancer outcomes and decreased toxicity. Online adaptive radiotherapy will be made possible by magnetic resonance imaging-guided radiotherapy (MRgRT) using a magnetic resonance linear accelerator (MR-Linac), which will enhance the visibility of malignancies. This review's objectives are to examine the benefits of MR-Linac as a treatment approach from the perspective of various cancer patients' prognoses and to suggest prospective development areas for additional study.
