Handling social considerations and the needs of different groups in public transport planning: a review of definitions, methods, and knowledge gaps
Authors: Hrelja Robert , Levin Lena , Camporeale Rosalia
Published: July 2024

This paper analyses the integration of social considerations into public transport planning. It addresses the challenge of balancing social benefits against objectives such as efficiency and cost minimization. Through a literature review, this paper examines methods for assessing public transport accessibility for potentially disadvantaged groups and identifies knowledge gaps in existing research. The analysis reveals a predominant focus on post-implementation (ex-post) accessibility assessments and a lack of research examining potential impacts (ex-ante) during planning stages. Furthermore, the paper identifies a lack of research on how to weigh social benefits against other more conventional objectives such as efficiency and cost minimization and also against environmental considerations. Research usually proposes changes ex-post based solely on a desire to improve accessibility for potentially disadvantaged groups. Therefore, there is a need for more research on how to manage conflicting interests in planning, for example through composite methods. The paper also highlights the tendency of research to overlook the practical usability of methods developed. The relevance of methods to policy makers and planners responsible for planning public transport systems remains largely unexplored. To develop practically useful methods, research needs a better understanding of the norms governing planning practices. It is common to discuss how the mobility needs of potentially disadvantaged passenger groups should be met in isolation from policy contexts. More research is needed about how the potential tensions between social, economic, and environmental considerations play out in public transport planning practices. All of this leads to a risk of a theory–practice gap, marked by a disconnect between research and the practical needs of the public transport providers. By proposing a more nuanced research approach that better reflects the complexity of real-world planning and the different needs of user groups, research can enable public transport planning for what we term ‘sustainable accessibility’.

Authors: Wang Na , Lin Weihong , Chen Xiaoli , Wu Gaojun , Fang Danhong
Published: July 2024

Background

In this study, we examine the association between the hyperuricemia(HU) and hypertension(HTN) in Chinese young adults. Besides, the correlation between the occurrence of thickened left ventricular wall and HU was identified in patients with HTN.

Methods

In all, 360 patients with HTN and 1991 young adults with normal blood pressure(NBP) were enrolled in the study. Participant characteristics were collected. Univariable and multivariable logistic regression tests were utilized to identify the correlation between the presence of HU and HTN, and the correlation between the occurrence of thickened ventricular septum and HU in patients with HTN.

Results

The prevalence of HU in Chinese young adults with HTN was significantly higher than young adults with NBP(36.39% vs. 16.93%). Univariable analyses revealed that 8 factors were related with the presence of HTN with p value < 0.001, including HU, male, body mass index(BMI) ≥ 24 kg/m2, total cholesterol(TC) > 5.17mmol/L, triglyceride(TG) > 1.70mmol/L, high density lipoprotein cholesterol(HDL-C) < 1.0mmol/L, fasting blood glucose(FBG) > 6.10mmol/L and fatty liver. After adjusting these covariates, multivariable analysis revealed that HU[odds ratio(OR):1.47, 95% confidence interval(CI): 1.10–1.95, p = 0.008] remained independent association with HTN in young adults. Additionally, univariable and multivariable logistic analyses revealed that HU kept the independent effect on the presence of thickened interventricular septum(adjusted OR = 1.81, 95% CI: 1.05–3.11, P = 0.03) and thickened left ventricular posterior wall(adjusted OR = 2.28, 95% CI: 1.28–4.08, P = 0.005) in young adults with HTN.

Conclusion

HU was independently associated with HTN in young adults. HU was independently correlated with thickened left ventricular wall, including interventricular septum and left ventricular posterior wall, in young adults with HTN.
Development and psychometric testing of a scale to measure effective rural emergency transfer (RET)
Authors: Mamalelala Tebogo T. , Holzemer William L. , Seloilwe Esther S. , Iwu Emilia
Published: July 2024

Background

The process of transferring patients from small rural primary care facilities to referral facilities impacts the quality of care and effectiveness of the referral healthcare system. The study aimed to develop and evaluate the psychometric properties of a scale measuring requirements for effective rural emergency transfer.

Methods

An exploratory sequential design was utilized to develop a scale designed to measure requirements for effective emergency transport. Phase one included a qualitative, interview study with 26 nursing transport providers. These transcripts were coded, and items developed for the proposed scale. Phase two included a content validity review by these 16 transport providers of the domains and items developed. Phase three included development and evaluation of psychometric properties of a scale designed to measure requirements for effective emergency transport. This scale was then tested initially with 84 items and later reduced to a final set of 58 items after completion by 302 transport nurses. The final scale demonstrated three factors (technology & tools; knowledge & skills; and organization). Each factor and the total score reported excellent scale reliability.

Results

The initial item pool consisted of 84 items, generated, and synthesized from an extensive literature review and the qualitative descriptive study exploring nurses’ experiences in rural emergency patient transportation. A two-round modified Delphi method with experts generated a scale consisting of 58 items. A cross-sectional study design was used with 302 nurses in rural clinics and health in four rural health districts. A categorical principal components analysis identified three components explaining 63.35% of the total variance. The three factors, technology, tools, personal knowledge and skills, and organization, accounted for 27.32%, 18.15 and 17.88% of the total variance, respectively. The reliability of the three factors, as determined by the Categorical Principal Component Analysis (CATPCA)’s default calculation of the Cronbach Alpha, was 0.960, 0.946, and 0.956, respectively. The RET Cronbach alpha was 0.980.

Conclusions

The study offers a three-factor scale to measure the effectiveness of emergency patient transport in rural facilities to better understand and improve care during emergency patient transport.

Authors: Xie Yue , Guo Ling-yun , Liu Bing , Hu Hui-li , Hu Bing , Chen Tian-ming , Qian Su-yun , Hei Ming-yan , Liu Gang
Published: July 2024

Background

Data on pyogenic liver abscess (PLA) of children in China have been limited. We aimed to summarize the clinical feather, microbiological characteristics, management, and outcome of PLA in children.

Method

We retrospectively reviewed PLA cases from January 2008 to June 2023 at Beijing Children’s Hospital. Clinical characteristics, pathogens and management were analyzed.

Results

We diagnosed 57 PLA patients in our center. The median onset age was 4.5 years and the male-to-female ratio was 1.6:1. The median diagnostic time was nine days and the median length of stay was 22 days. Twenty-eight patients (49.1%) had predisposing factors, around 71.4% of the patients had malignant hematology and primary immunodeficiency disease. Patients with underlying factors were more likely to have extrahepatic organ involvement (p = 0.024), anemia (p < 0.001), single abscess (p = 0.042), unilateral involvement (p = 0.039), and small size of the abscess (p = 0.008). Twenty-four patients (42.1%) had extrahepatic organ involvement. Pathogens were identified in 17 patients (29.8%), the most common pathogens were Klebsiella pneumoniae and Staphylococcus aureus. The positive rate of metagenomic next-generation sequencing (mNGS) was 87.5% (7/8). On multivariable analysis, the extrahepatic organ involved (p = 0.029) and hepatomegaly (p = 0.025) were two independent factors associated with poor outcomes.

Conclusions

PLA is usually seen in children with predisposing factors. Malignant hematology and primary immunodeficiency disease were the most common underlying diseases. Extrahepatic organ involvement and hepatomegaly are associated with poor prognosis. Increased use of mNGS could be beneficial for identifying pathogens.

Authors: Hejazi Sima , Manzour Rezvaneh , Shahsavari Arezoo , Ghasemi Saeed , Roshan-Nejad Mahdieh
Published: July 2024

Background

The Coronavirus disease 2019 (COVID-19) pandemic has significantly affected various aspects of public health. The virus poses a particular threat to individuals with kidney failure undergoing hemodialysis and their caregivers. The present study investigated the experience of family caregivers of individuals undergoing hemodialysis about caring during the COVID-19 pandemic in Iran.

Methods

This qualitative study was conducted with 17 family caregivers of individuals undergoing hemodialysis in Bojnurd, Iran using inductive qualitative content analysis. The participants were selected using convenience and purposive sampling method with maximum variation. Semi-structured interviews were used in data collection based on the interview guide. The data were analyzed with MAXQDA10.

Results

The results culminated in the identification of a main category of the COVID-19 care burden on caregivers and two generic categories including the COVID-19 Overt (financial/constraining) care burden (subcategories: Non-adherence to Health Protocols, COVID-19 Financial Costs, COVID-19 Restrictions and Hemodialysis Appointments, and Decreased Caregiver Support during the COVID-19 Era), and the COVID-19 Covert (emotional/psychological) Care Burden (subcategories: Caregiver’s Loneliness in the Care, Stress of Contracting COVID-19, Psychological Consequences of individuals undergoing hemodialysis Staying at Home, The burden of other Individuals’ Expectations of the Caregiver, and Physical and emotional pressure on the Caregiver).

Conclusion

Caregivers during the COVID-19 period have experienced both overt and covert care burden. The results of this study can contribute to understanding the experiences of caregivers of individuals with chronic diseases such as kidney failure, in critical conditions like the COVID-19 pandemic, by healthcare teams and devising strategies and programs to support them.
Health systems response to climate change adaptation: a scoping review of global evidence
Authors: Ansah Edward Wilson , Amoadu Mustapha , Obeng Paul , Sarfo Jacob Owusu
Published: July 2024

Background

The health system plays a critical role in safeguarding the well-being of communities in the face of health risks associated with climate change. This review maps evidence on health systems' adaptation to climate risk and barriers to effective adaptation.

Methods

This review followed the recommendations by Arksey and O’Malley for conducting scoping review. Search for records was conducted in PubMed, Central, Web of Science, JSTOR, Google, and Google Scholar. Only peer-reviewed papers published in English language were included in this review. All the 63 included studies were critically appraise d.

Results

We found that efforts are being made to create resilient health systems by incorporating climate change into health policies. Investments are being made in innovative technologies, climate-resilient health infrastructure, enhancing healthcare delivery, developing the capacity of climate specialists and agencies to provide high-quality evidence for resilient health systems. We also found that several obstacles prevent health system adaptation to climate risk, including poor policy implementation and evaluation. The obstacles are further exacerbated by financial constraints, including poverty, a lack of political commitment, inadequate data, and deficient healthcare systems, especially in developing countries. There is also a lack of integration of climate change into mental health actions and the health and safety of healthcare workers.

Conclusion

Efforts to develop resilient health systems against climate risks are underway, but persistent obstacles, including inadequate policy implementation, resource limitations, and a lack of integration of climate change into critical health domains, hinder comprehensive adaptation measures, particularly in developing nations.
Perceived discrimination, mental health help-seeking attitudes, and suicide ideation, planning, and attempts among black young adults
Authors: Boyd Donte T. , Quinn Camille R. , Durkee Myles I. , Williams Ed-Dee G. , Constant Andrea , Washington Durrell , Butler-Barnes Sheretta T. , Ewing Aldenise P.
Published: July 2024

Background

Developing an understanding of the negative impact of discrimination is critical when examining the suicidality of Black young adults in the US. Suicide rates among Black young adults have increased at alarming rates. One of the reasons for this increase is the disparities related to access to mental health services, which has long-term health consequences. This study addresses a significant gap in the literature by examining associations between experiences of everyday discrimination, attitudes towards mental health help-seeking attitudes, on the outcomes suicide ideation, planning to die by suicide, and suicide attempts.

Methods

The data came from a national study of the experiences of Black young adults regarding mental, physical, and sexual health. Participants were recruited from across the Midwestern region of the United States through Qualtrics Panels, an online survey delivery service used to recruit study participants. The total sample for this study was N = 362, and the average age of the sample was 21 (SD: 1.96). We used a logistic regression analysis to examine the role of everyday discrimination, mental health support-seeking attitudes, and covariates on the outcomes: suicide ideation, planning to die by committing suicide, and suicide attempts.

Results

Black young adults with positive mental health help-seeking attitudes were 34% less likely to attempt suicide (OR = 0.66; 95% CI: 0.46, 0.96) and 35% less likely to experience suicide ideation (OR = 0.65; 95% CI: 0.47, 0.89). However, those young adults who experienced discrimination daily were more likely to report having attempted suicide (OR = 1.70; 95% CI: 1.34, 2.15).

Conclusions

Our findings offer valuable insights into the complex interplay between experiences of discrimination, attitudes toward seeking mental health support, and suicidal behaviors. However, our research also underscores how experiences of discrimination can significantly exacerbate feelings of isolation, hopelessness, and inadequacy, further contributing to suicidal behaviors in this population. By promoting positive mental health help-seeking behaviors, actively addressing discrimination, and applying an intersectional approach to suicide prevention efforts, we can take significant strides towards building a more supportive and inclusive society. This approach aims to empower individuals to seek help, reduce the risk of suicidal behaviors, and create a more welcoming environment for all members of our community.
Associations of cognitive appraisal and patient activation on disability and mental health outcomes: a prospective cohort study of patients undergoing spine surgery
Authors: Skolasky Richard L. , Finkelstein Joel A. , Schwartz Carolyn E.
Published: July 2024

Background

With the increased use of patient-reported outcomes measures (PROMs) to assess spine surgery outcomes, it is important to understand how patients interpret their health changes over time. The measurement of cognitive-appraisal processes enables the quantification of how individuals think about quality of life (QOL). This study examined how appraisal processes were associated with patients’ views of their role in managing their health—patient activation.

Methods

This longitudinal cohort study from August 2019 to January 2022 included 222 adults undergoing spine surgery for cervical (n = 107) and/or lumbar (n = 148) pathology at an academic medical center. PROMs assessed disability (Neck Disability Index for cervical or Oswestry Disability Index for lumbar) and mental health (PROMIS-29 v2.0), cognitive-appraisal processes (QOLAPv2-SF), and patient activation (Patient Activation Measure). ANOVA models were used to examine the relationships between QOL and cognitive appraisal processes before and after surgery, overall and stratified by patient-activation stage. Effect sizes facilitated interpretation.

Results

There were significant improvements in pain-related disability and mental health following surgery. Cognitive appraisal processes explained substantial amounts of variance, particularly with changes in mental health (45% before surgery, 75% at three months, and 63%, at 12-months after surgery). With respect to physical disability, less disability was associated with a lesser focus on negative aspects of QOL. Appraisal explained the most variance before surgery for high-activation patients. At 12-months post-surgery, however, appraisal explained the most variance for the low-activation patients. Appraisal explained similar amounts of variance in mental health at baseline and three-months post-surgery for all activation groups, but substantially more variance in the low-activation group at 12-months post-surgery. There were differences in the direction of appraisal-outcome associations by activation group in selected appraisal items/domains.

Conclusions

Cognitive-appraisal processes demonstrate a significant relationship with QOL among spine surgery patients. These processes explain substantial variance in pain-related disability and mental health, especially among those high in activation before surgery and those low in activation at 12-months post-surgery. Our findings suggest that patients’ ways of thinking about their health may be effective targets of motivational coaching, to help them become more engaged over the recovery trajectory.
Efficacy and safety of transcutaneous auricular vagus nerve stimulation for frequent premature ventricular complexes: rationale and design of the TASC-V trial
Authors: Liu Yu , Wei Xinyao , Wang Lixin , Yang Yanling , Xu Liya , Sun Tianheng , Yang Li , Cai Song , Liu Xiaojie , Qin Zongshi , Bin Lulu , Sun Shaoxin , Lu Yao , Cui Jiaming , Liu Zhishun , Wu Jiani
Published: July 2024

Background

Premature Ventricular Complexes (PVCs) are very common in clinical practice, with frequent PVCs (more than 30 beats per hour) or polymorphic PVCs significantly increasing the risk of mortality. Previous studies have shown that vagus nerve stimulation improves ventricular arrhythmias. Stimulation of the auricular distribution of the vagus nerve has proven to be a simple, safe, and effective method to activate the vagus nerve. Transcutaneous au ricular vagus nerve stimulation (taVNS) has shown promise in both clinical and experimental setting for PVCs; however, high-quality clinical studies are lacking, resulting in insufficient evidence of efficacy.

Methods

The study is a prospective, randomized, parallel-controlled trial with a 1:1 ratio between the two groups. Patients will be randomized to either the treatment group (taVNS) or the control group (Sham-taVNS) with a 6-week treatment and a subsequent 12-week follow-up period. The primary outcome is the proportion of patients with a ≥ 50% reduction in the number of PVCs monitored by 24-hour Holter. Secondary outcomes include the proportion of patients with a ≥ 75% reduction in PVCs, as well as the changes in premature ventricular beats, total heartbeats, and supraventricular premature beats recorded by 24-hour Holter. Additional assessments compared score changes in PVCs-related symptoms, as well as the score change of self-rating anxiety scale (SAS), self-rating depression scale (SDS), and 36-item short form health survey (SF-36).

Discussion

The TASC-V trial will help to reveal the efficacy and safety of taVNS for frequent PVCs, offering new clinical evidence for the clinical practice.

Translation and psychometric evaluation of the Korean version of the Reproductive Concerns After Cancer Scale (RCAC)
Authors: Kang Sook Jung , An Hae Jeong , Hwang Woon Young , Lee Hyerim , Kim Yoonjung
Published: July 2024

Background

Improving cancer survival rates highlights post-treatment fertility implications for reproductive-aged women. To provide fertility care for cancer survivors, nurses need instruments to assess and communicate reproductive concerns with cancer survivors and healthcare providers. This study aimed to translate the Reproductive Concerns after Cancer Scale (RCAC) into Korean and examine its psychometric properties in young female cancer survivors in South Korea.

Methods

The RCAC was translated into Korean, involving expert bilingual translators for initial translation and reverse translation for cultural and semantic accuracy. In detail, the RCAC was translated into Korean and evaluated in a preliminary study involving 10 cancer survivors. Subsequently, a revised version of the instrument was administered to 182 cancer survivors and a psychometric evaluation was conducted. The process included verifying content validity, and then assessing construct validity using exploratory factor analysis and criterion validity. The reliability of the instrument was quantified by measuring its internal consistency using Cronbach’s alpha.

Results

The translated RCAC demonstrated an item-level content validity index of 1.0 and a scale-level index of 1.0. The content was finalized based on preliminary survey findings, which revealed that all participants thought the instrument was clear. The Korean version of the RCAC demonstrated a satisfactory level of validity per exploratory factor analysis, which resulted in a 14-item instrument consisting of three subscales: “fertility potential” (six items), “health problem” (five items), and “acceptance” (three items). The items and subscales explained 57.6% of the variance. Criterion validity was confirmed through an analysis of the correlation between the Korean version of the RCAC and both the FACT-G (r = -0.36, p
< .001) and PHQ-9 (r = 0.38, p
< .001). Cronbach’s alpha coefficient of the Korean version of the RCAC was 0.83.

Conclusions

The Korean version of the RCAC is a valid and reliable instrument for assessing reproductive concerns in female cancer survivors. Thus, this instrument can be used to provide tailored care to female cancer survivors of reproductive age by clarifying and assess their reproductive concerns. This may support the development of guidelines or policies to provide care for those with reproductive concerns who require nursing care.

Published: July 2024

Background

Geroscience focuses on interventions to mitigate molecular changes associated with aging. Lifestyle modifications, medications, and social factors influence the aging process, yet the complex molecular mechanisms require an in-depth exploration of the epigenetic landscape. The specific epigenetic clock and predictor effects of a vegan diet, compared to an omnivorous diet, remain underexplored despite potential impacts on aging-related outcomes.

Methods

This study examined the impact of an entirely plant-based or healthy omnivorous diet over 8 weeks on blood DNA methylation in paired twins. Various measures of epigenetic age acceleration (PC GrimAge, PC PhenoAge, DunedinPACE) were assessed, along with system-specific effects (Inflammation, Heart, Hormone, Liver, and Metabolic). Methylation surrogates of clinical, metabolite, and protein markers were analyzed to observe diet-specific shifts.

Results

Distinct responses were observed, with the vegan cohort exhibiting significant decreases in overall epigenetic age acceleration, aligning with anti-aging effects of plant-based diets. Diet-specific shifts were noted in the analysis of methylation surrogates, demonstrating the influence of diet on complex trait prediction through DNA methylation markers. An epigenome-wide analysis revealed differentially methylated loci specific to each diet, providing insights into the affected pathways.

Conclusions

This study suggests that a short-term vegan diet is associated with epigenetic age benefits and reduced calorie intake. The use of epigenetic biomarker proxies (EBPs) highlights their potential for assessing dietary impacts and facilitating personalized nutrition strategies for healthy aging. Future research should explore the long-term effects of vegan diets on epigenetic health and overall well-being, considering the importance of proper nutrient supplementation.

Exploring the relationship between condition severity and health-related quality of life in people with haemophilia A across Europe: a multivariable analysis of data from the CHESS II study
Authors: Ferri Grazzi Enrico , Hawes Charles , Camp Charlotte , Hinds David , O’Hara Jamie , Burke Tom
Published: July 2024

Background

Haemophilia A (HA; Factor VIII deficiency) is a congenital X-linked bleeding disorder characterized by trauma-related or spontaneous bleeding events, most notably arising within the intraarticular space and resulting in chronic inflammation and degeneration of affected joints. Endogenous clotting factor activity relative to normal levels determines the severity of HA symptoms, as mild (> 5–40%), moderate (1–5%), or severe (< 1%). Within the current environment of rapid evolution in HA management, we seek to understand the interplay of condition severity and health-related quality of life (HRQoL) to characterise and differentiate unmet needs among people with HA (PwHA).

Methods

A generalised linear regression model (GLM) was developed to explore the relationship between HA severity and EQ-5D-5 L index score from adult HA patients sampled in the “Cost of Haemophilia across Europe – a Socioeconomic Survey II” (CHESS II) cross-sectional, retrospective burden of illness study among adults with hereditary haemophilia A or B from eight European countries. HA patients of any severity with no active inhibitors during the 12 months prior to data capture and a completeEQ-5D-5 L response were included. A base GLM model was specified with covariates for demographic and clinical characteristics (age, body mass index, country, employment, HA severity, annual bleeding rate, problem joints, and chronic pain).

Results

Of 381 evaluable patients, 221 (58.0%) had severe HA, 96 (25.2%) had moderate HA, and 64 (16.8%) had mild HA. Among the covariates included in the GLM model and after controlling for haemophilia-related outcomes, a significant association was observed between mild HA and higher EQ-5D-5 L index score (average marginal effects, 0.084; p = 0.016) relative to severe HA. Patient country of residence and magnitude of HA-related chronic pain were also associated with significant differences in index scores, with the latter showing a negative relationship with HRQoL outcomes.

Conclusions

Condition severity and chronic pain are significant predictors of HRQoL in PwHA. Durable bleeding protection and effective management of chronic pain have the potential to address unmet treatment needs in this population.
Comparison of the measurement properties and consistency between the EQ-5D-3L and EQ-5D-Y-3L in adolescents aged 15–17 in China
Authors: Wang Jiefu , Hong Tianqi , Fang Haoran , Luo Chang , He Xiaoning , Xie Shitong
Published: July 2024

Objective

To evaluate and compare the measurement properties and consistency between the Chinese versions of EQ-5D-3L and EQ-5D-Y-3L among Chinese adolescent populations aged 15–17 years.

Methods

Chinese adolescents aged 15–17 studying in high school were recruited through online survey. Social-demographic characteristics and self-reported EQ-5D-3L and EQ-5D-Y-3L responses were collected in the survey. The consistency of responses between the two measures was assessed using redistribution property, and the consistency of utility values was assessed by intraclass correlation coefficients (ICC). Convergent validity and known-group validity were examined using Spearman’s rank correlation, F-test and effect sizes, respectively. Sensitivity was compared using relative efficiency (RE).

Results

762 respondents (48.8% male; age 15–17 years;) were recruited. The EQ-5D-3L showed a more severe ceiling effect than EQ-5D-Y-3L (78.2% vs. 66.0%). Respondents reported higher proportions of having problems in four dimensions using the EQ-5D-Y-3L than using the EQ-5D-3L. The consistency of corresponding dimensions between the two measures was relatively good, while non-negligible proportions of inconsistency were observed in “pain/discomfort” (11.4%) and “anxiety/depression” (15.7%) dimensions. The ICC of the utility values between the EQ-5D-3L and EQ-5D-Y-3L was 0.852 (p < 0.001). The Spearman’s rank correlation (range: 0.385–0.620) indicated an acceptable convergent validity between the correlative dimensions of the EQ-5D-3L and EQ-5D-Y-3L. The EQ-5D-Y-3L had a higher efficiency than the EQ-5D-3L at detecting differences across EQ VAS subgroups (ES = 1.793 for EQ-5D-3L, ES = 1.920 for EQ-5D-Y-3L). Mixed results were observed in sensitivity.

Conclusions

Both the EQ-5D-3L and EQ-5D-Y-3L are demonstrated to be valid and generally consistent for measuring HRQoL among adolescents aged 15–17 years in China. Respondents reported higher proportions of having problems using the EQ-5D-Y-3L than using the EQ-5D-3L. More research is warranted to compare the discriminant validity and test-retest reliability between the two measures.
The Buerger’s rabbit model: a closer step to unravelling thromboangiitis obliterans?
Authors: Li Jia-Long , Kwan Kristine J. S. , Lin Xue-Guang , Wang Jie , Chen Bo , Lu Yi-Jie , Wang Bo , Xie Shi-Shuai , Zhou Jiong , Yu Bo , Deng Ying , Jiang Shuai , Tang Jing-Dong
Published: July 2024

Objective

Thromboangiitis obliterans (TAO) remains clinical challenging due to its rarity and underwhelming management outcomes. This study aimed to describe a novel TAO rabbit model that demonstrates a closer resemblance to TAO.

Methods

Thirty-six New Zealand rabbits underwent the surgical implantation of calibrated gelatin sponge particles (CGSPs) into their right femoral artery. The CGSPs were soaked in different solutions to simulate different types of thrombi: normal (NT; normal saline); inflammatory TAO thrombus (TAO; dimethylsulfoxide [DMSO]), and DMSO with methotrexate (MTX). All groups underwent clinical assessment, digital subtraction angiography (DSA) and histopathological analysis at time points day 0 (immediate), week 1 (acute), week 2 (subacute), and week 4 (chronic).

Results

The TAO rabbit presented with signs of ischemia of the right digit at week 4. On DSA, the TAO rabbits exhibited formation of corkscrew collaterals starting week 1. On H&E staining, gradual CGSP degradation was observed along with increased red blood cell aggregation and inflammatory cells migration in week 1. On week 2, disorganization of the tunica media layer and vascular smooth muscle cell (VSMC) proliferation was observed. In the TAO rabbit, migrated VSMCs, inflammatory cells, and extracellular matrix with collagen-like substances gradually occluded the lumen. On week 4, the arterial lumen of the TAO rabbit was filled with relatively-organized VSMC and endothelial cell clusters with less inflammatory cells. Neorevascularization was found in the MTX-treated group.

Conclusion

The novel TAO rabbit model shows a closer resemblance to human TAO clinically, radiographically, and histopathologically. Histological analysis of the IT progression in the TAO model suggests that it is of VSMC origin.
Single-cell hdWGCNA reveals metastatic protective macrophages and development of deep learning model in uveal melanoma
Authors: Sun Yifang , Wu Jian , Zhang Qian , Wang Pengzhen , Zhang Jinglin , Yuan Yonggang
Published: July 2024

Background

Although there has been some progress in the treatment of primary uveal melanoma (UVM), distant metastasis remains the leading cause of death in patients. Monitoring, staging, and treatment of metastatic disease have not yet reached consensus. Although more than half of metastatic tumors (62%) are diagnosed within five years after primary tumor treatment, the remainder are only detected in the following 25 years. The mechanisms of UVM metastasis and its impact on prognosis are not yet fully understood.

Methods

scRNA-seq data of UVM samples were obtained and processed, followed by cell type identification and characterization of macrophage subpopulations. High-dimensional weighted gene co-expression network analysis (HdWGCNA) was performed to identify key gene modules associated with metastatic protective macrophages (MPMφ) in primary samples, and functional analyses were conducted. Non-negative matrix factorization (NMF) clustering and immune cell infiltration analyses were performed using the MPMφ gene signatures. Machine learning models were developed using the identified metastatic protective macrophages related genes (MPMRGs) to distinguish primary from metastatic patients. A deep learning convolutional neural network (CNN) model was constructed based on MPMRGs and cell type associations. Lastly, a prognostic model was established using the MPMRGs and validated in independent cohorts.

Results

Single-cell RNA-seq analysis revealed a unique immune microenvironment landscape in primary samples compared to metastatic samples, with an enrichment of macrophage cells. Using HdWGCNA, MPMφ and marker genes were identified. Functional analysis showed an enrichment of genes related to antigen processing progress and immune response. Machine learning and deep learning models based on key genes showed significant effectiveness in distinguishing between primary and metastatic patients. The prognostic model based on key genes demonstrated substantial predictive value for the survival of UVM patients.

Conclusion

Our study identified key macrophage subpopulations related to metastatic samples, which have a profound impact on shaping the tumor immune microenvironment. A prognostic model based on macrophage cell genes can be used to predict the prognosis of UVM patients.
Cross-talk between circRNAs and m6A modifications in solid tumors
Authors: Liu Fenfang , Gu Wendong , Shao Yingjie
Published: July 2024

Circular RNAs (circRNAs) possess unique biological properties and distribution characteristics that enable a variety of biological functions. N6-methyladenosine (m6A), a prevalent epigenetic modification in organisms, is regulated by factors including methyltransferases (writers), demethylases (erasers), and m6A-binding proteins (readers). These factors play critical roles in various pathophysiological processes. There is growing evidence that m6A modifications are common within circRNAs, affecting their synthesis, translation, translocation, degradation, and stability. Additionally, circRNAs regulate biological processes that influence m6A modifications. This review explores the metabolism and functions of m6A modifications and circRNAs, their interactions, and their specific regulatory mechanisms in different tumors, offering insights into m6A-circRNA interaction in cancer.

Diabetic retinopathy (DR), a well-known microvascular complication of diabetes mellitus, remains the main cause of vision loss in working-age adults worldwide. Up to now, there is a shortage of information in the study regarding the contributing factors of DR in diabetes. Accumulating evidence has identified glycemic variability (GV), referred to fluctuations of blood glucose levels, as a risk factor for diabetes-related complications. Recent reports demonstrate that GV plays an important role in accounting for the susceptibility to DR development. However, its exact role in the pathogenesis of DR is still not fully understood. In this review, we highlight the current landscape and relevant mechanisms of GV in DR, as well as address the mechanism-based therapeutic strategies, aiming at better improving the quality of DR management in clinical practice.

Traumatic brain injury (TBI) remains a leading cause of death and disability that places a great physical, social, and financial burden on individuals and the health system. In this review, we summarize new research into the metabolic changes described in clinical TBI trials, some of which have already shown promise for informing injury classification and staging. We focus our discussion on derangements in glucose metabolism, cell respiration/mitochondrial function and changes to ketone and lipid metabolism/oxidation to emphasize potentially novel biomarkers for clinical outcome prediction and intervention and offer new insights into possible underlying mechanisms from preclinical research of TBI pathology. Finally, we discuss nutrition supplementation studies that aim to harness the gut/microbiome-brain connection and manipulate systemic/cellular metabolism to improve post-TBI recovery. Taken together, this narrative review summarizes published TBI-associated changes in glucose and lipid metabolism, highlighting potential metabolite biomarkers for clinical use, the cellular processes linking these markers to TBI pathology as well as the limitations and future considerations for TBI “omics” work.

Background

Lung cancer, which is diagnosed two to three times more frequently in patients over the age of 70, is a leading cause of cancer-specific mortality. Given the elevated risk of morbidity and mortality, surgical intervention may not always be the most appropriate primary treatment option. This study aims to evaluate specific risk factors associated with postoperative morbidity and mortality in elderly patients and to optimize patient selection therefore improving surgical outcomes.

Patients and methods

The study encompassed a cohort of 73 patients aged 75 and above who underwent surgical treatment for non-small cell lung cancer (NSCLC) at the Department of Thoracic Surgery of the P. Hertsen Moscow Oncological Research Institute between 2015 and 2021. All patients underwent preoperative evaluation, including PET/CT staging and functional assessment, carried out by a multidisciplinary team comprising thoracic surgeons, anesthesiologists, and other medical specialists.

Results

The investigation revealed a postoperative mortality rate of 5.5% and a postoperative morbidity incidence of 16.4%, with occurrences of atrial fibrillation in 41.6%, persistent air leak in 33.3%, and pneumonia in 25% of complicated cases. At the one-year follow-up, 88% of patients remained free from relapse, whereas at three years, this rate stood at 66%. During the follow-up period, 16 patients (22%) passed away, with a median survival duration of 44 months. Survival rates at one year, three years, and five years were 71%, 66%, and 35%, respectively. Multivariate analysis disclosed several significant factors predicting a complex postoperative period, including stage IIIb (p = 0.023), pN1 (p = 0.049), pN2 (p = 0.030), and central location (p = 0.007). Additionally, overall survival was primarily influenced by a Charlson comorbidity index of 6 (p = 0.044), stage Ia2 (p = 0.033), and the necessity for thoracotomy (p = 0.045).

Conclusion

Each case of lung cancer in patients aged 75 and older necessitates an individualized approach. Given the higher mortality rate relative to younger patients, comprehensive risk assessment and preoperative management of underlying comorbidities are imperative, with the involvement of anesthesiologists, intensive care physicians, cardiologists, and other relevant specialists as needed.

Background

To understand the clinical characteristics and prognosis of respiratory syncytial virus (RSV)-related encephalopathy in children.

Methods

A retrospective analysis of the data of children who were diagnosed with RSV-related encephalopathy and admitted to the paediatric intensive care unit (PICU) of Beijing Children’s Hospital between November 2016 and November 2023 was performed.

Results

Four hundred and sixty-four children with RSV infection were treated in the PICU, and eight of these patients (1.7%) were diagnosed with RSV-related encephalopathy. The mean age of the patients was 24.89 (5.92 ∼ 36.86) months. Two patients had underlying diseases. The time from the onset of illness to impaired consciousness was 3 (1.88–3.75) days. Five patients had convulsions, and three patients had an epileptic status. The serum procalcitonin (PCT) level was 1.63 (0.24, 39.85) ng/ml for the eight patients, and the cerebrospinal fluid (CSF) protein level was 232 (163 ∼ 848) g/L. Among the 8 patients, four patients underwent electroencephalogram (EEG) monitoring or examination. One patient showed continuous low-voltage, nonresponsive activity, and another patient displayed persistent slow waves, the remaining two patients had negative results. One patient had a combination of acute necrotizing encephalopathy (ANE) and acute encephalopathy with biphasic seizures and late reduced diffusion (AESD). Additionally, one patient had ANE, and another had acute brain swelling (ABS). One patient died in the hospital, and the other seven patients were discharged with improvement. Routine follow-up was conducted for 4.58(0.5 ∼ 6.50) years, and all patients fully recovered.

Conclusions

RSV-related encephalopathy could have varying clinical manifestations, and some types, such as ANE and ABS, are dangerous and can lead to death.

Authors: Adechina Adefounke Prudencia , Assogba Yaou Pierrot , Tchiakpe Edmond , Yessoufou Akadiri
Published: July 2024

Background

Antiretroviral drugs in people living with HIV-1 (PLHIV-1) often trigger side effects which may lead to discontinuation or failure of treatment. Human Leukocyte Antigen B*57:01 (HLA-B*57:01) allele is known to predict hypersensitivity reactions to Abacavir. Very few data are available on the prevalence of HLA-B*57:01 allele in PLHIV-1 in African countries. This study aimed to screen for HLA-B*57:01 allele in PLHIV-1 in Benin.

Methods

This pilot study was carried out on one hundred ten PLHIV-1 enrolled in two health facilities in Benin. Socio-demographic and clinical data were collected. Biological data were determined and HLA-B*57:01 allele was genotyped, using Single Specific Primer-Polymerase Chain Reaction in blood samples.

Results

70% of participants were female. PLHIV-1 were under TDF + 3TC + DTG (47.2%) or TDF + 3TC + EFV (57.3%). Their median age was 41 [36-48.75] years and the average CD4 + T cell count was 249 [130-381.25] cells/µl. The average viral load in treatment failure PLHIV-1 was 4.7 [3.9–5.2] Log10. At the inclusion date, twenty-nine (26.4%) PLHIV-1 under TDF + 3TC + EFV have developed hypersensitivity reactions. None of 110 patients had shown HLA-B*5701 allele.

Conclusion

Our study revealed that HLA-B*57:01 allele was very rare in PLHIV-1 in Benin, suggesting that its screening before starting the Abacavir regimen did not seem necessary.

Published: July 2024

Background

An epidemic of Hepatitis E infection occurred in Kitgum district, northern Uganda in 2009. In that epidemic, more than 10,422 people were infected, and over 166 deaths were registered. Kitgum District Health Management Information Systems (HMIS) showed that Hepatitis E cases continued to occur in Mucwini more than in Kitgum Matidi sub-county despite instituting similar epidemic control measures in the two communities. The tenacity of the virus in Mucwini sub-county had remained unclear. This study aimed to assess communities’ views and perspectives on the differential prevalence of Hepatitis E in the two sub-counties of Kitgum Matidi and Mucwini in northern Uganda.

Methods

A mixed study using qualitative and quantitative methods was used. Four Focus group discussions and six key informant interviews were conducted with the village health teams, local council chairpersons, health workers, and community members. These participants were chosen purposively because of their expertise and experience in community health services. Face-to-face interview guides were administered to obtain detailed information on factors associated with the differential occurrence of Hepatitis E in the two sub-counties. This study was approved by a local IRB and the Uganda National Council of Science and Technology (UNCS&T).

Results

The most substantial findings were the differences in prevention and control practices in the two communities. Residents of Mucwini were less compliant with infection, prevention, and control guidelines, and disagreements between local councilors and village health teams in Mucwini over allowances led to poor implementation and non-adherence to guidelines on community control of the epidemic.

Conclusion

A differentially higher prevalence of Hepatitis E in Mucwini than in Kitgum Matidi resulted from poor personal and community hygiene and non-adherence to behavior change communication among residents of Mucwini than their counterparts in Kitgum Matidi. The authors recommend a more proactive approach to managing an epidemic by securing the willingness of the affected community to adopt appropriate infection prevention and control guidelines. In addition, disagreements among stakeholders should be resolved quickly so that all community members adhere to control measures.
