Published: July 2024

Background:

Treatment strategies for meniscal tears range from nonoperative management to surgical intervention. However, national trends in cost-related outcomes and patient factors related to the failure of nonoperative management remain poorly understood.

Purpose:

To describe the costs associated with nonoperative versus operative management of meniscal tears in the 2 years after diagnosis and examine the relationship between patient characteristics and timing of surgery.

Study Design:

Cross-sectional study; Level of evidence, 3.

Methods:

This study was conducted using the MarketScan databases. Patients diagnosed with a meniscal tear without concomitant knee osteoarthritis between January 1 and December 31, 2017, were included. The primary outcome was the total cost of meniscal tear-related procedures—including insurance deductibles, coinsurance, and net insurance payments—in the 2 years after diagnosis. Procedures included were as follows: (1) surgery—including meniscectomy or meniscal repair; (2) physical therapy; (3) medication—including nonsteroidal anti-inflammatories, opioids, and acetaminophen; (4) intra-articular injections—including professional fee, hyaluronic acid, and corticosteroids; (5) imaging; and (6) clinic visits to orthopaedic specialists. Patients were grouped as having undergone early surgery (ES) (≤3 months of diagnosis), late surgery (LS) (>3 months after diagnosis), or no surgery (NS). Multivariate logistic regression was performed to determine the likelihood of undergoing surgery early and failing nonoperative treatment.

Results:

The study population included 29,924 patients with a mean age of 43.9 ± 12.9 years (ES: n = 9507 (31.8%); LS: n = 2021 (6.8%); NS: n = 18,396 (61.5%)). Complex (36.6%) and medial (58.8%) meniscal tears were the most common type and location of injuries, respectively. The mean cost of management per patient was $3835 ± $4795. Costs were lower in the NS group ($1905 ± $3175) compared with the ES group ($6759 ± $5155), while the highest costs were observed in the LS group ($7649 ± $5913) ( P < .001). Patients who were men, >40 years, and with a bucket-handle or lateral meniscal tear were more likely to undergo surgery early. Patients who were men, <30 years, and with a complex tear or tear to the lateral meniscus were more likely to fail nonoperative management.

Conclusion:

Nonoperative management had the lowest cost burden and should be recommended for patients with appropriate indications. However, if surgery is necessary, it should be performed earlier.

Introduction: To explore opportunities for individualized postoperative positioning duration in macular hole (MH) surgery. Methods: This post hoc analysis comprised eyes that had full-thickness MH (FTMH) repair in the prospective DISCOVER intraoperative optical coherence tomography (OCT) study. Preoperative spectral-domain OCT (SD-OCT) and postoperative day 1 (POD1) trans-tamponade OCT were analyzed. Preoperative SD-OCT macular cubes were imported and analyzed using a machine learning–enhanced segmentation platform. Nine preoperative segmentation parameters were analyzed (maximum foveal height, apex area, base area, central foveal area, maximum apex diameter, maximum base diameter, maximum depth, minimum foveal width, volume). In addition, 2 new metrics—the macular hole index and tractional hole index—were calculated. POD1 trans-tamponade OCTs were obtained and evaluated for hole closure. Results: Of the 66 eyes with an FTMH, 16 (24%) had a chronic MH and 5 (8%) were reoperations from FTMH nonclosure after previous surgery. Nine eyes (14%) had an open MH on POD1 trans-tamponade OCT (6 chronic MHs [66%]; 2 reoperations [22%]); the remaining 57 MHs (86%) were closed. Multiple segmentation parameters were significantly associated with POD1 closure. Conclusions: Volumetric MH measurements and trans-tamponade POD1 OCT closure status are important in predicting MH closure speed and the need for postoperative positioning. Individualized positioning duration in MH could lower perioperative morbidity and vastly enhance quality of life.

Published: July 2024

The present study proposes an innovative transdermal drug delivery system using ferrocene-incorporated fibers to enhance the bioavailability and therapeutic efficacy of ascorbyl tetraisopalmitate. Using electrospinning technology, the authors created ferrocene polymer fibers capable of highly efficient drug encapsulation and controlled release in response to reactive oxygen species commonly found in wound sites. The approach improves upon previous methods significantly by offering higher drug loading capacities and sustained release, directly targeting diseased cells. The results confirm the potential of ferrocene fibers for localized drug delivery, potentially reducing side effects and increasing patient convenience. The method could facilitate the application of bioactive compounds in medical textiles and targeted therapy.

Published: July 2024

This in vivo mouse model study was conducted to investigate the temporal alteration of the function of CD36 in salivary secretion. CD36 was highly expressed in the parotid gland of BALB/c mice. No significant variations were shown in the CD36 levels in the 8-, 48-, and 72-week-old animals. However, pilocarpine-induced salivary secretion was reduced in an age-dependent manner, showing a significantly low level at the age of 72 weeks. Pilocarpine-induced salivary secretion was significantly reduced by pretreatment with a CD36 inhibitor at 8 and 48 weeks, but not at 72 weeks. In senescence-accelerated mice (SAM), the pilocarpine-induced salivary secretion was significantly reduced at the age of 56 weeks, and a significantly lower amount of CD36 was demonstrated in the parotid gland, compared with the control. These results suggest that the involvement of parotid CD36 in mouse salivary secretion is altered with age.

Published: July 2024

Background

White lupin (Lupinus albus L.) is a high-protein Old World grain legume with remarkable food and feed production interest. It is sown in autumn or early spring, depending on the local agroclimatic conditions. This study aimed to identify allelic variants associated with vernalization responsiveness, in order to improve our knowledge of legume flowering regulatory pathways and develop molecular selection tools for the desired phenology as required for current breeding and adaptation to the changing climate.

Results

Some 120 white lupin accessions originating from a wide range of environments of Europe, Africa, and Asia were phenotyped under field conditions in three environments with different intensities of vernalization, namely, a Mediterranean and a subcontinental climate sites of Italy under autumn sowing, and a suboceanic climate site of France under spring sowing. Two hundred sixty-two individual genotypes extracted from them were phenotyped in a greenhouse under long-day photoperiod without vernalization. Phenology data, and marker data generated by Diversity Arrays Technology sequencing (DArT-seq) and by PCR-based screening targeting published quantitative trait loci (QTLs) from linkage map and newly identified insertion/deletion polymorphisms in the promoter region of the FLOWERING LOCUS T homolog, LalbFTc1 gene (Lalb_Chr14g0364281), were subjected to a genome-wide association study (GWAS). Population structure followed differences in phenology and isolation by distance pattern. The GWAS highlighted numerous loci significantly associated with flowering time, including four LalbFTc1 gene promoter deletions: 2388 bp and 2126 bp deletions at the 5’ end, a 264 bp deletion in the middle and a 28 bp deletion at the 3’ end of the promoter. Besides LalbFTc1 deletions, this set contained DArT-seq markers that matched previously published major QTLs in chromosomes Lalb_Chr02, Lalb_Chr13 and Lalb_Chr16, and newly discovered QTLs in other chromosomes.

Conclusions

This study highlighted novel QTLs for flowering time and validated those already published, thereby providing novel evidence on the convergence of FTc1 gene functional evolution into the vernalization pathway in Old World lupin species. Moreover, this research provided the set of loci specific for extreme phenotypes (the earliest or the latest) awaiting further implementation in marker-assisted selection for spring- or winter sowing.

Background

Unfavourable lipid and glucose levels may play a crucial role in the pathogenesis of gestational diabetes mellitus (GDM). However, there is a lack of prospective studies on the relationship between lipid profiles, lipid ratios and GDM during pregnancy.

Aims

To prospectively investigate the relationship between lipid profile and lipid ratios in early and mid-pregnancy and their pattern of change from early to mid-pregnancy and the risk of GDM.

Methods

This nested case-control study was based on maternal and child healthcare hospitals from Fujian Province, China. We included pregnant women who delivered in the hospital from January 2021 to June 2023. Lipid profiles (TC, TG, ApoA1, ApoB, HDL-c, LDL-c) and fasting glucose were measured before 14 weeks of gestation and between 20 and 28 weeks of gestation, and lipid ratios (triglyceride glucose index, TG/HDL-c and TC/HDL-c) was constructed. Logistic regression was used to assess the relationship between lipid profile, lipid ratios and GDM.

Results

Of 1586 pregnant women, 741 were diagnosed with GDM. After adjusting for potential confounders, TG, ApoA1, ApoB, LDL-c, triglyceride glucose index, TG/HDL-c, and TC/HDL-c in early pregnancy were positively associated with the risk of GDM (odds ratios [95% CI] for extreme interquartile comparisons were 2.040 (1.468–2.843), 1.506 (1.091–2.082), 1.529 (1.110–2.107), 1.504 (1.086–2.086), 1.952 (1.398–2.731), 2.127 (1.526–2.971), and 2.370 (1.700-3.312), all trend P < 0.05). HDL-c was negatively associated with the risk of GDM (0.639: 0.459–0.889, trend P all less than 0.05). Similarly, in mid-pregnancy, lower levels of HDL-c, higher levels of triglyceride glucose index, TG/HDL-c ratio, and TC/HDL-c ratio were associated with increased risk of GDM (all trends P < 0.05). Stably high levels (both ≥ median for early and mid-pregnancy) of triglyceride glucose index, TG/HDL-c and TC/HDL-c were associated with increased risk of GDM (OR [95% CI]: 2.369 (1.438–3.940), 1.588 (1.077–2.341), 1.921 (1.309–2.829), respectively). The opposite was true for HDL-c, where stable high levels were negatively associated with GDM risk (OR [95% CI]: 0.599 (0.405–0.883)).

Conclusion

Increases in triglyceride glucose index, TG/HDL-c ratio, and TC/HDL-c ratio in early and mid-pregnancy, as well as their stable high levels from early to mid-pregnancy, are associated with a higher risk of GDM. In contrast, increased levels of HDL-c, both in early and mid-pregnancy, and their stable high levels from early to mid-pregnancy were associated with a lower risk of GDM. That highlighted their possible clinical relevance in identifying those at high risk of GDM.
Cytokines in PD-1 immune checkpoint inhibitor adverse events and implications for the treatment of uveitis
Authors: Brown Aaron C. , Quiroz José , Parikh Devayu A. , Li Yafeng , Ritzer Lukas , Rosen Richard , Deobhakta Avnish
Published: July 2024

Immune checkpoint inhibitors (ICI) such as Programmed cell Death 1 (PD-1) inhibitors have improved cancer treatment by enhancing the immune system’s ability to target malignant cells. Their use is associated with immune-related adverse events (irAEs), including uveitis. The profile of pro-inflammatory cytokines underlying Anti-PD-1-induced uveitis shares significant overlap with that of non-infectious uveitis. Current corticosteroid treatments for uveitis while effective are fraught with vision threatening side effects. The cytokine profile in ICI-related uveitis has a large overlap with that of noninfectious uveitis, this overlap strongly supports the potential for therapy that activates the PD-1 axis in the eye to treat uveitis. Indeed, ICI related uveitis often resolves with cessation of the ICI, restoring the endogenous PD-1 axis. The potential benefit of targeting many pro-inflammatory cytokines via local PD-1 axis activation is mitigating ocular inflammation while minimizing adverse effects.

Published: July 2024

Food insecurity is a global public health issue associated with noncommunicable diseases. Individual factors are strongly associated with food insecurity, but there is limited literature on the broader impact of both the social and food environments on food insecurity in non-English speaking European countries, given that the research was predominantly conducted in Anglophone settings. In addition, these studies have mostly been conducted in urban areas. Therefore, this study aimed to identify the main determinants of food insecurity among adults living in peri-urban areas in Flanders, Belgium. Data on socio-demographics, neighborhood social cohesion, social isolation, and perceived food environments were collected from 567 adults through a self-administered questionnaire, and objective data on the food environment were obtained through (commercial) databases on food outlets. Food insecurity was measured using the USDA Household Food Security Survey Module. Multivariable logistic regression models revealed that lower socioeconomic status (OR14.11,95%CI:4.72;61.11), reasonable (OR4.16,95%CI: 2.11;8.47) to poor and very poor (OR6.54,95%CI: 2.11;8.47) subjective health status, and living in private (OR7.01, 95% CI:3.0;17.0) or government-assisted (OR6.32,95%CI: 3.13;13.26) rental housing significantly increased the odds of food insecurity. Additionally, residing in a neighborhood with low (OR2.64, 95% CI:1.13;6.26) to medium (OR2.45,95% CI:1.21;5.11) social cohesion, having a neutral opinion (OR4.12,95%CI:1.51;11.54) about the availability of fruit and vegetables in one's neighborhood, and having an opinion that fruit and vegetable prices are too expensive (OR5.43,95% CI 2.26;14.4) significantly increased the odds of experiencing food insecurity. This study underscores the need for policies that consider factors related to social and food environments, in addition to individual factors, to effectively address food insecurity.
“I would love to see these big institutions… throwing their weight around”: qualitative findings regarding health and social sector collaborations to address community-level socioeconomic adversity
Authors: Brown Erika M. , Fraze Taressa K. , Gottlieb Laura M. , Fichtenberg Caroline
Published: July 2024

Background

Health and social sector organizations are increasingly working together to mitigate socioeconomic adversity within their communities. We sought to learn about the motivations, experiences, and perspectives of organizations engaged in these collaborations.

Methods

We conducted semi-structured, 60-minute interviews with 34 leaders from 25 health and social sector organizations between January-April 2021. Interviews explored motivations, benefits and challenges, and ways in which health sector organizations can most effectively address community-level socioeconomic adversity. Interviews were audio recorded and transcribed; themes were coded using Dedoose software.

Results

Partnerships were primarily motivated by mission-driven organizations and key health sector leaders who were interested in addressing root causes of poor health; policies such as certificate of need laws and value-based care incentives that aligned community-level investments with health sector organizations’ financial interests facilitated these efforts. While partnerships were mostly regarded as mutually beneficial ways to increase impact (for the health sector) and resource access (for the social sector), social sector organizations voiced frustrations regarding the outsized expectations, unsustained interest, and lack of partnership from their health sector collaborators. Despite these frustrations, both health and social sector interviewees supported the health sector’s continued involvement in community-level socioeconomic initiatives and expansion of policy and systems efforts.

Conclusions

Cross-sector, community-level socioeconomic initiatives were mutually beneficial, but social sector organizations experienced more frustrations. Policy and organizational changes within the health sector can further mobilize and sustain support for these efforts.
Can good neighbourhood perception magnify the positive effect of favourable built environment on recreational walking in China?
Authors: Guo Huagui , Li Yayu , Liu Yufei , Zhang Shuyu , Zhang Yanji , Ho Hung Chak
Published: July 2024

Background

It remains unknown whether good neighbourhood perception can enhance the benefits of favourable built environment to physical activity. Moreover, the moderation pattern is less understood in developing countries.

Objectives

This work aims to examine the moderation effects of perceived neighbourhood safety and aesthetics on the relationship between built environment and time for recreational walking.

Methods

We performed the examination using a sample of 760 residents in Fuzhou City, China. The Negative Binomial Regression Model was developed to examine the moderation roles of neighbourhood safety and aesthetics on the impact of built environment, adjusting for the effects of location, socioeconomic, personal preferences and social environment factors. Moreover, two sensitivity analyses were performed to test whether the moderators found are robust to the control of residential self-selection, and differential measures of conceptually-comparable aspects of built environment.

Results

We found stronger associations of time for recreational walking with road density and proportion of parks and squares POIs for residents with high perception of neighbourhood safety, compared to those with low perception of neighbourhood safety. There was a greater effect of the proportion of parks and squares POIs, when perceived aesthetics was high than when perceived aesthetics was low. The findings of neighbourhood safety and aesthetics as moderator, were robust in the two sensitivity analyses. No significant moderation effect was found for land use diversity.

Conclusions

High perceived neighbourhood safety can magnify the positive effects of road connectivity and accessibility to parks and squares. Neighbourhood aesthetics positively moderates the association of time for recreational walking with accessibility to parks and squares. The findings emphasize the need to consider safety- and aesthetics-specific differences in estimates of built environment effects. Improvements in neighbourhood safety and aesthetics are key to effective interventions in built environment to better promote physical activity.
Non-participation in breast screening in Denmark: Sociodemographic determinants
Authors: von Euler-Chelpin My , Napolitano George , Lynge Elsebeth , Borstrøm Søren , Vejborg Ilse
Published: July 2024

Background

Internationally, non-participation in breast screening increased with decreasing level of education indicating importance of information campaigns to enhance awareness of screening. However, in Denmark in the 1990s the association between education and non-participation was U-shaped. We therefore analyzed recent Danish data.

Methods

Data derived from the Capital Region of Denmark, biennial, organized breast screening program 2008–2020, where women aged 50–69 were personally invited to screening. Non-participation was measured as number of women with no participation out of women eligible for at least three invitations. Sociodemographic determinants were identified by linkage to public registers. Results were reported as age adjusted odds ratios (OR) of non-participation including 95% confidence intervals (CI).

Results

Among 196,085 women, 86% participated. Using women with low education as baseline, the OR for professional bachelors was 0.64; and for academics 0.75. The strongest determinants of non-participation were being non-married OR 2.03; born outside Denmark OR 2.04; being self-employed OR 1.67; retired OR 3.12; on public support OR 3.66; or having co-morbidity OR 1.56.

Conclusion

The U-shaped association between education and non-participation in breast screening prevailed. The data further indicated that screening participation was low in women with pertinent health and social problems.

Published: July 2024

Background

Adverse birth outcomes, including preterm birth, low birth weight, and stillbirth, remain a major global health challenge, particularly in developing regions. Understanding the possible risk factors is crucial for designing effective interventions for birth outcomes. Accordingly, this study aimed to develop a predictive model for adverse birth outcomes among childbearing women in Sub-Saharan Africa using advanced machine learning techniques. Additionally, this study aimed to employ a novel data science interpretability techniques to identify the key risk factors and quantify the impact of each feature on the model prediction.

Methods

The study population involved women of childbearing age from 26 Sub-Saharan African countries who had given birth within five years before the data collection, totaling 139,659 participants. Our data source was a recent Demographic Health Survey (DHS). We utilized various data balancing techniques. Ten advanced machine learning algorithms were employed, with the dataset split into 80% training and 20% testing sets. Model evaluation was conducted using various performance metrics, along with hyperparameter optimization. Association rule mining and SHAP analysis were employed to enhance model interpretability.

Results

Based on our findings, about 28.59% (95% CI: 28.36, 28.83) of childbearing women in Sub-Saharan Africa experienced adverse birth outcomes. After repeated experimentation and evaluation, the random forest model emerged as the top-performing machine learning algorithm, with an AUC of 0.95 and an accuracy of 88.0%. The key risk factors identified were home deliveries, lack of prenatal iron supplementation, fewer than four antenatal care (ANC) visits, short and long delivery intervals, unwanted pregnancy, primiparous mothers, and geographic location in the West African region.

Conclusion

The region continues to face persistent adverse birth outcomes, emphasizing the urgent need for increased attention and action. Encouragingly, advanced machine learning methods, particularly the random forest algorithm, have uncovered crucial insights that can guide targeted actions. Specifically, the analysis identifies risky groups, including first-time mothers, women with short or long birth intervals, and those with unwanted pregnancies. To address the needs of these high-risk women, the researchers recommend immediately providing iron supplements, scheduling comprehensive prenatal care, and strongly encouraging facility-based deliveries or skilled birth attendance.
A retrospective descriptive review of community-engaged research projects addressing rural health priorities
Authors: Nasir Bushra Farah , Chater Bruce , McGrail Matthew , Kondalsamy-Chennakesavan Srinivas
Published: July 2024

Background

Most rural populations experience significant health disadvantage. Community-engaged research can facilitate research activities towards addressing health issues of priority to local communities. Connecting scholars with community based frontline practices that are addressing local health and medical needs helps establish a robust pipeline for research that can inform gaps in health provision. Rural Health Projects (RHPs) are conducted as part of the Doctor of Medicine program at the University of Queensland. This study aims to describe the geographic coverage of RHPs, the health topic areas covered and the different types of RHP research activities conducted. It also provides meaningful insight of the health priorities for local rural communities in Queensland, Australia.

Methods

This study conducted a retrospective review of RHPs conducted between 2011 and 2021 in rural and remote Australian communities. Descriptive analyses were used to describe RHP locations by their geographical classification and disease/research categorisation using the International Classification of Diseases and Related Health Problems – 10th Revision (ICD-10) codes and the Human Research Classification System (HRCS) categories.

Results

There were a total of 2806 eligible RHPs conducted between 2011 and 2021, predominantly in Queensland (n = 2728, 97·2%). These were mostly conducted in small rural towns (under 5,000 population, n = 1044, 37·2%) or other rural towns up to 15,000 population (n = 842, 30·0%). Projects mostly addressed individual care needs (n = 1233, 43·9%) according to HRCS categories, or were related to factors influencing health status and contact with health services (n = 1012, 36·1%) according to ICD-10 classification.

Conclusions

Conducting community focused RHPs demonstrates a valuable method to address community-specific rural health priorities by engaging medical students in research projects while simultaneously enhancing their research skills.
Core contents for a menopausal health literacy intervention for South Korean middle-aged women: an e-Delphi study
Authors: Lee Haein , Kim Junghee
Published: July 2024

Background

The attention on improving health literacy (HL) for self-management at the population level in many countries has been increasing. Although self-management among middle-aged women in the menopausal transition are important public health issues, few studies have developed the menopausal HL intervention reflecting the multidimensional aspects of HL. We aimed to generate consensus from an expert panel on the core contents of the menopausal HL intervention for middle-aged women based on the HL conceptual framework of the European Health Literacy Survey.

Methods

The panel comprised 20 experts from multiple disciplines (nursing, medicine, public health, and food and nutrition). We conducted the e-Delphi process in three rounds, asking the panel to evaluate and prioritize the appropriateness of the core contents and provide open-ended responses to additional comments about the menopausal HL intervention. The e-Delphi questionnaire was developed based on the HL framework, integrating health and HL domains.

Results

The experts reached a consensus on 38 components of the intervention. Among the 19 components of the four health domains, health topics in healthcare and disease prevention were more appropriate than those in health promotion. For the 19 HL competency components, strengthening the ability to access, appraise, and apply health information was more important than strengthening the ability to understand information. Finally, a consensus was achieved on the 12 priorities for intervention content by HL domains integrated with health domains. For example, contents included proper access to reliable information resources, understanding the definition and process of menopause, judging abnormal health symptoms, and performing the health checkups necessary for menopausal women.

Conclusions

Our findings provide evidence for HL skills that nurses and other health professionals can consider when developing interventions to improve self-management among middle-aged women. Future research should focus on incorporating the core contents of multidimensional HL skills into menopausal HL interventions to improve self-management among middle-aged women.
Feasibility and acceptability of studying full-time nurse faculty salaries
Authors: Malin Kathryn J. , Zemlak Jessica , Christianson Jaqueline , Leiberg Jessica , Grabert Lisa
Published: July 2024

Background

The nursing shortage is driven, in part, by the critical shortage of nursing faculty. Consequently, qualified potential nursing students are being turned away from nursing schools each year. The preeminent issue influencing the United States nurse faculty workforce shortage is salary; financial compensation is higher in clinical and private-sector settings than educational settings. The purpose of this study is to describe current full-time nurse faculty salary, sources of income, and perceived need for more income, as well as the feasibility and acceptability of research focused on full-time nurse faculty salaries, so to guide future nursing faculty workforce research.

Methods

Using a cross-sectional study design, full-time nursing faculty working in a Midwestern state in the United States completed a survey inclusive of fixed choice and free text response options focused on income (individual gross, faculty, and secondary), demographics, and feasibility/acceptability of the survey instrument. Descriptive statistics were used to describe salary, sources of income, and perceived need for additional income. Feasibility and acceptability were evaluated by descriptive statistics examining three feasibility and acceptability questions, and by comparing demographic differences between participants who answered income questions compared to those who did not using t tests, x2 tests, and Wilcoxon signed rank tests.

Results

One hundred and eighty-three full-time nurse faculty completed the survey in six weeks, representing 27% of the full-time nurse faculty workforce in the state. Over half of participants, 57%, reported having another job(s) in addition to their full-time faculty position to support basic living expenses. Most respondents reported willingness to share financial/salary data and viewed the survey to be acceptable.

Conclusions

Research focused on nursing faculty salaries was feasible and acceptable to those who chose to participate in the study. Perceived income needs may be an important factor driving career decisions for nursing faculty. Future research should focus on delineating how salary influences the decision to enter or stay in the nursing faculty workforce. Further, this study can inform policy recommendations on how to best measure and report nurse faculty salary and the gap between clinical salaries and faculty salaries.

Published: July 2024

Background

Uterine corpus endometrial carcinoma (UCEC) is a prevalent gynecologic malignancy with a favorable prognosis if detected early. However, there is a lack of accurate and reliable early detection tests for UCEC. This study aims to develop a precise and non-invasive diagnostic method for UCEC using circulating cell-free DNA (cfDNA) fragmentomics.

Methods

Peripheral blood samples were collected from all participants, and cfDNA was extracted for analysis. Low-coverage whole-genome sequencing was performed to obtain cfDNA fragmentomics data. A robust machine learning model was developed using these features to differentiate between UCEC and healthy conditions.

Results

The cfDNA fragmentomics-based model showed high predictive power for UCEC detection in training (n = 133; AUC 0.991) and validation cohorts (n = 89; AUC 0.994). The model manifested a specificity of 95.5% and a sensitivity of 98.5% in the training cohort, and a specificity of 95.5% and a sensitivity of 97.8% in the validation cohort. Physiological variables and preanalytical procedures had no significant impact on the classifier’s outcomes. In terms of clinical benefit, our model would identify 99% of Chinese UCEC patients at stage I, compared to 21% under standard care, potentially raising the 5-year survival rate from 84 to 95%.

Conclusion

This study presents a novel approach for the early detection of UCEC using cfDNA fragmentomics and machine learning showing promising sensitivity and specificity. Using this model in clinical practice could significantly improve UCEC management and control, enabling early intervention and better patient outcomes. Further optimization and validation of this approach are warranted to establish its clinical utility.
FFP2 induced breathing resistance does not affect metabolism and well-being during brisk walking and stair climbing - a randomized controlled trial
Authors: Engeroff Tobias , Hartel Niclas , Niederer Daniel , Nienhaus Albert , Groneberg David A. , Vogt Lutz
Published: July 2024

Objectives

N95 or Type II filtering face pieces (FFP2) are often worn during work hours or on public transportation to prevent airborne infection. The aim of this randomized controlled crossover study is to assess the impact of FFP2 induced breathing resistance on pulmonary function, blood gas values and discomfort during walking and stair climbing.

Methods

N = 16 healthy adults (24.8 ± 2.2 years; 10 females, ) participated. Interventions included (1) six minutes of walking in a 16-meter-long hallway (612 m) and (2) eight minutes of stair climbing in a two-story staircase (420 stairs), both with and without a FFP2 (> 48 h wash-out). Spiroergometric data (Ventilation, breathing frequency, tidal volume, oxygen uptake and carbon dioxide exhalation (primary outcome), end tidal carbon dioxide- and oxygen pressure) and self-reported response (Perceived exertion, dyspnoea and pain) were assessed during activities. Blood gas analysis (capillary carbon dioxide- (pCO2) (primary outcome) and oxygen partial pressure (pO2), pH, lactate and base excess) was measured immediately after cessation of activities. Manipulation effects (FFP2 versus no mask) were tested using repeated measures analyses of variance.

Results

Analysis showed no effect of FFP2 on pCO2 or other blood-gas parameters but on carbon dioxide exhalation during walking: (mean 1067, SD 209 ml/min) (mean 1908, SD 426 ml/min) (F(15) = 19.5; p < 0.001; ηp2 = 0.566) compared to no mask wearing (mean 1237, SD 173 ml/min; mean 1908, SD 426 ml/min). Ventilation was decreased and dyspnoea was increased by FFP2 during activities. FFP2 led to lower oxygen uptake and lower end tidal oxygen but higher end tidal carbon dioxide during stair climbing.

Conclusions

FFP2 decreased ventilation based on slower breathing patterns and led to limitations in pulmonary gas exchange and increased subjective dyspnoea. However, invasive diagnostics revealed no signs of clinically relevant metabolic effects immediately after everyday physical activities.

Published: July 2024

Stroke is a significant global burden, causing extensive morbidity and mortality. In metabolic states where glucose is limited, ketone bodies, predominantly β-hydroxybutyrate (BHB), act as alternative fuel sources. Elevated levels of BHB have been found in the ischemic hemispheres of animal models of stroke, supporting its role in the pathophysiology of cerebral ischemia. Clinically, higher serum and urinary BHB concentrations have been associated with adverse outcomes in ischemic stroke, highlighting its potential utility as a prognostic biomarker. In both animal and cellular models, exogenous BHB administration has exhibited neuroprotective effects, reduction of infarct size, and improvement of neurological outcomes. In this review, we focus on the role of BHB before and after ischemic stroke, with an emphasis on the therapeutic potential and mechanisms of ketone administration after ischemic stroke.

Published: July 2024

Background

It has been proposed that anti-angiogenesis therapy could induce tumor "vascular normalization" and further enhance the efficacy of chemotherapy, radiotherapy, target therapy, and immunotherapy for nearly twenty years. However, the detailed molecular mechanism of this phenomenon is still obscure.

Method

Overexpression and knockout of CCL28 in human lung adenocarcinoma cell line A549 and murine lung adenocarcinoma cell line LLC, respectively, were utilized to establish mouse models. Single-cell sequencing was performed to analyze the proportion of different cell clusters and metabolic changes in the tumor microenvironment (TME). Immunofluorescence and multiplex immunohistochemistry were conducted in murine tumor tissues and clinical biopsy samples to assess the percentage of pericytes coverage. Primary pericytes were isolated from lung adenocarcinoma tumor tissues using magnetic-activated cell sorting (MACS). These pericytes were then treated with recombinant human CCL28 protein, followed by transwell migration assays and RNA sequencing analysis. Changes in the secretome and metabolome were examined, and verification of retinoic acid metabolism alterations in pericytes was conducted using quantitative real-time PCR, western blotting, and LC–MS technology. Chromatin immunoprecipitation followed by quantitative PCR (ChIP-qPCR) was employed to validate the transcriptional regulatory ability and affinity of RXRα to specific sites at the ANGPT1 promoter.

Results

Our study showed that after undergoing anti-angiogenesis treatment, the tumor exhibited a state of ischemia and hypoxia, leading to an upregulation in the expression of CCL28 in hypoxic lung adenocarcinoma cells by the hypoxia-sensitive transcription factor CEBPB. Increased CCL28 could promote tumor vascular normalization through recruiting and metabolic reprogramming pericytes in the tumor microenvironment. Mechanistically, CCL28 modified the retinoic acid (RA) metabolism and increased ANGPT1 expression via RXRα in pericytes, thereby enhancing the stability of endothelial cells.

Conclusion

We reported the details of the molecular mechanisms of "vascular normalization" after anti-angiogenesis therapy for the first time. Our work might provide a prospective molecular marker for guiding the clinical arrangement of combination therapy between anti-angiogenesis treatment and other therapies.
Administration of bicarbonates through percutaneous gastrostomy with continuous nocturnal infusion in a patient with Kearns-Sayre disease: a life changing therapeutical paradigm
Authors: Traunero Arianna , Baldo Francesco , Magnolato Andrea , Di Leo Grazia , Barbi Egidio , Bruno Irene
Published: July 2024

Background

Mitochondrial diseases (MDs) are systemic disorders that can affect multiple organs. Renal manifestations, including renal tubular acidosis, are common because kidneys are particularly vulnerable to energy deprivation. Treatment of MDs is often complex and electrolyte replacement can be difficult especially in pediatric patients, because large and repeated amounts of oral supplements are needed but are not well tolerated.

Case presentation

We describe the case of a girl affected by Kearns-Sayre disease with severe renal tubular acidosis. The management of her metabolic acidosis was challenging because she showed persistent low levels of serum bicarbonates despite a progressive incrementation of oral bicarbonates. Furthermore, as a result to the ingestion of large amounts of alkali, the girl developed an aversion to oral supplementation. After positioning a percutaneous gastrostomy (PEG) and starting enteral administration of bicarbonates (with daily boluses and continuous nocturnal infusion), she finally obtained an adequate electrolyte control, with a significant increase in her quality of life.

Conclusions

In MDs, the combination of nocturnal continuous enteral administration of alkali plus diurnal boluses may represent a valid solution to correct metabolic acidosis. It can also result in an improved patients’ quality of life, particularly in pediatric settings, where compliance to oral therapy is often lacking due to the large and repeated amounts of unpalatable bicarbonates solutions required.

Published: July 2024

Background

Transient erythroblastopenia of childhood (TEC) is an acquired, self-limited pure red cell aplasia that usually occurs in children 4 years old and younger. This clinical condition has been priorly described to be linked to numerous viral and immunologic mechanisms. COVID-19, caused by the coronavirus SARS-CoV-2, was initially discovered in China in December 2019. The disease quickly spread worldwide, resulting in pandemic.

Case Presentation

This manuscript reports a new clinically relevant condition associated to COVID-19, describing a child with clinical and biochemical signs of Pure Red Blood cells aplasia and complete absence of erythroblasts at the bone marrow needle aspiration with signs of erythrophagocytosis, resembling morphological signs such as in hemophagocytic lymphohistiocytosis (HLH), temporally associated to SARS-CoV-2 infection.

Conclusion

This report highlights a newly described continuum laboratory and clinical spectrum of immune/hematological dysregulations secondary to SARS-CoV-2. SARS-CoV‐2 infection-linked TEC has never been described in literature, but, according to our findings, should be considered in all the patients with transient erythroblastopenia without congenital red blood cell abnormalities and serology negative for major infections associated with TEC. This condition must be considered in the same spectrum of MIS-C and the inter-links among the two clinical manifestations, as well as a potential interdependence among them, should be considered in the future.
