A computational algorithm for optimal design of a bioartificial organ scaffold architecture
Authors: Bukač Martina , Čanić Sunčica , Muha Boris , Wang Yifan 
Published: November 2024

We develop a computational algorithm based on a diffuse interface approach to study the design of bioartificial organ scaffold architectures. These scaffolds, composed of poroelastic hydrogels housing transplanted cells, are linked to the patient’s blood circulation via an anastomosis graft. Before entering the scaffold, the blood flow passes through a filter, and the resulting filtered blood plasma transports oxygen and nutrients to sustain the viability of transplanted cells over the long term. A key issue in maintaining cell viability is the design of ultrafiltrate channels within the hydrogel scaffold to facilitate advection-enhanced oxygen supply ensuring oxygen levels remain above a critical threshold to prevent hypoxia. In this manuscript, we develop a computational algorithm to analyze the plasma flow and oxygen concentration within hydrogels featuring various channel geometries. Our objective is to identify the optimal hydrogel channel architecture that sustains oxygen concentration throughout the scaffold above the critical hypoxic threshold.
The computational algorithm we introduce here employs a diffuse interface approach to solve a multi-physics problem. The corresponding model couples the time-dependent Stokes equations, governing blood plasma flow through the channel network, with the time-dependent Biot equations, characterizing Darcy velocity, pressure, and displacement within the poroelastic hydrogel containing the transplanted cells. Subsequently, the calculated plasma velocity is utilized to determine oxygen concentration within the scaffold using a diffuse interface advection-reaction-diffusion model. Our investigation yields a scaffold architecture featuring a hexagonal network geometry that meets the desired oxygen concentration criteria. Unlike classical sharp interface approaches, the diffuse interface approach we employ is particularly adept at addressing problems with intricate interface geometries, such as those encountered in bioartificial organ scaffold design. This study is significant because recent developments in hydrogel fabrication make it now possible to control hydrogel rheology and utilize computational results to generate optimized scaffold architectures.
Important features of bench press performance in non-disabled and Para athletes: A scoping review
Authors: Buhmann Rob , Sayers Mark , O’Brien Julia , Borg David 
Published: November 2024

Purpose
Understanding important features for performance in non-disabled bench press and Paralympic powerlifting may inform talent identification and transfer models. The aim of this scoping review was to describe features associated with bench press performance.

Methods
We conducted a systematic search of three electronic databases (PubMed, SportDiscus and EMBASE) to identify studies involving non-disabled and Para athlete populations that investigated features related to bench press one-repetition maximum (1RM), across six domains (anthropometric, body composition, demographic, technical, disability and neuromuscular). Search terms included “resistance training”, “para powerlifting’ and “one repetition max”. No date restrictions were include in searches. Studies using adult participants, with at least six-months of bench press experience, who were able to bench press their body mass were included.

Results
Thirty-two studies met our inclusion criteria. Twenty-four studies involved non-disabled athletes (total n = 2,686; 21.9% female) and eight involved Para athletes (total n = 2,364; 39.4% female). Anthropometric (17 studies) and body composition (12 studies) features were most studied; half of the 32 studies investigated features from a single domain. Of anthropometric variables, upper arm circumference shared the strongest association with bench press 1RM in non-disabled (r = 0.87) and para-athletes (r = 0.65). Upper limb fat free mass (r = 0.91) and body mass index (r = 0.46) were the body composition variables sharing the strongest association with bench press 1RM in non-disabled and para-athletes. Few studies considering the uncertainty of their results. Practices of open and transparent science, such as pre-registration and data sharing, were absent.

Conclusion
The development of bench press talent identification and sport transfer models will require future studies to investigate both non-training and training modifiable features, across multiple domains. Large longitudinal studies using information from athlete monitoring databases and multivariable model approaches are needed to understand the interacting features associated with bench press performance, and for the development of talent identification models.
Smoking cessation and prognosis during long-term follow-up after stroke, TIA, and acute coronary syndrome—results from the randomized controlled NAILED trial
Authors: Irewall Anna-Lotta , Åslund Lina , Ögren Joachim , Mooe Thomas 
Published: November 2024

Background and aims
About 50% of patients continue to smoke after stroke and myocardial infarction. We aimed to assess the effect of a multiple risk factor intervention on long-term smoking cessation and to explore a possible association between early smoking cessation and long-term prognosis.

Material and methods
Consecutive patients with stroke/TIA/acute coronary syndrome (ACS) at Östersund Hospital during 2010–2014 were included, randomized to intervention or usual care (1:1), and followed through 2017. This substudy included participants that reported current smoking during hospitalization and were alive at 1 month post discharge when the intervention began (n = 321). The smoking cessation intervention was part of a telephone-based, multiple risk factor intervention delivered by a nurse and consisted of brief advice delivered annually. Smoking cessation at the last follow-up was analyzed as the primary outcome. Smoking cessation at other time points and association between early smoking cessation and prognosis (CV events, survival) were secondary outcomes.

Result
After a mean follow-up of 4.2 years, 171 participants reported nonsmoking, with no significant difference between the intervention and control group (50.3% vs. 56.3%, absolute difference 5.9%, 95% CI −5.0 to 16.7, p = 0.286). Of these, 80.7% had stopped smoking within 1 month after discharge. The intervention did not improve smoking cessation proportions in the long or short term, and there was no apparent effect on smoking cessation attempts or sustained abstinence. Smoking cessation within 1 month was associated with lower all-cause mortality (HR 0.52, 95% CI 0.32–0.87), and there was a nonsignificant trend towards a lower incidence of CV events (HR 0.71, 95% CI 0.45–1.12).

Conclusion
Annual brief advice by a nurse as part of a multiple risk factor follow-up did not improve long-term smoking cessation after stroke/TIA/ACS. Continued smoking past 1 month was associated with worse prognosis.

Published: November 2024

Background
Breast cancer patients face significant psychological challenges, including difficulties in accepting the diagnosis, treatment, and long-term impact of the disease. Acceptance and Commitment Therapy (ACT) has shown promise in enhancing acceptance and psychological flexibility in various populations. This study aims to investigate the effectiveness of ACT in promoting disease acceptance among breast cancer patients through a randomized controlled trial.

Methods
This study will recruit 90 breast cancer patients and randomly allocate them to an ACT intervention or control group. The ACT intervention, focusing on acceptance, mindfulness, value clarification, and committed action, will be delivered over 4 weeks. Meanwhile, the control group will receive standard care with non-therapeutic intervention. The study’s primary outcome is disease acceptance, while secondary outcomes include depression, anxiety, social support, quality of life (QoL), and psychological inflexibility. Data will be collected at three points: baseline, post-intervention, and three-month follow-up. Statistical analysis will compare outcomes between groups to evaluate the effectiveness and mechanism of this intervention using covariance and mediation analysis.

Discussion
This study evaluates the effectiveness of ACT in promoting disease acceptance among breast cancer patients. It hypothesizes that the ACT group will show higher disease acceptance and improvements in social support, QoL, and psychological flexibility compared to the control group. The findings will contribute to research on psychological interventions and demonstrate ACT’s effectiveness in enhancing disease acceptance.

Trial registration
The research project is registered in the ClinicalTrials (NCT05327153).

Authors: Liu Wenchi , Yu Xing , Chen Jinhong , Chen Weizhi , Wu Qiaoyi 
Published: November 2024

Background
People with traumatic brain injury (TBI) are at high risk for infection and sepsis. The aim of the study was to develop and validate an explainable machine learning(ML) model based on clinical features for early prediction of the risk of sepsis in TBI patients.

Methods
We enrolled all patients with TBI in the Medical Information Mart for Intensive Care IV database from 2008 to 2019. All patients were randomly divided into a training set (70%) and a test set (30%). The univariate and multivariate regression analyses were used for feature selection. Six ML methods were applied to develop the model. The predictive performance of different models were determined based on the area under the curve (AUC) and calibration curves in the test cohort. In addition, we selected the eICU Collaborative Research Database version 1.2 as the external validation dataset. Finally, we used the Shapley additive interpretation to account for the effects of features attributed to the model.

Results
Of the 1555 patients enrolled in the final cohort, 834 (53.6%) patients developed sepsis after TBI. Six variables were associated with concomitant sepsis and were used to develop ML models. Of the 6 models constructed, the Extreme Gradient Boosting (XGB) model achieved the best performance with an AUC of 0.807 and an accuracy of 74.5% in the internal validation cohort, and an AUC of 0.762 for the external validation. Feature importance analysis revealed that use mechanical ventilation, SAPSII score, use intravenous pressors, blood transfusion on admission, history of diabetes, and presence of post-stroke sequelae were the top six most influential features of the XGB model.

Conclusion
As shown in the study, the ML model could be used to predict the occurrence of sepsis in patients with TBI in the intensive care unit.

Published: November 2024

Background
Hypertension is a risk factor for cardiovascular events. Inflammation plays an important role in the development of essential hypertension. Studies assessing the association between complete blood count-based inflammatory scores (CBCIS) and hypertension are scarce. Therefore, this study aimed to determine the relationship between CBCIS and hypertension among individuals with and without human immunodeficiency virus (HIV).

Method
This was a cross-sectional study among 344 participants at Serenje District Hospital and Serenje Urban Clinic. We used structured questionnaires to collect sociodemographic, clinical and laboratory characteristics. CBCIS included lymphocyte-monocyte ratio (LMR), neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), derived neutrophil-lymphocyte ratio (d-NLR), and differential white blood cells. The primary outcome variable was hypertension defined as systolic and diastolic blood pressure higher than or equal to 140/90 mmHg. Logistic regression was used to estimate the association between hypertension and CBCIS in statistical package for social science (SPSS) version 22.0.

Results
The participants had a median age of 32 years (interquartile range (IQR) 24–42) and 65.1% (n = 224) were female. The prevalence of hypertension was 10.5% (n = 36). Among those with hypertension, 55.6% (n = 20) were female and 44.4% (n = 16) were male. The CBCIS significantly associated with hypertension in people living with HIV (PLWH) was PLR (adjusted odds ratio (AOR) 0.98; 95% confidence interval (CI) 0.97–0.99, p = 0.01) while in people without HIV, AMC (AOR 15.40 95%CI 3.75–63.26), ANC (AOR 1.88 95%CI 1.05–3.36), WBC (AOR 0.52 95%CI 0.31–0.87) and PLR (AOR 0.98 95%CI 0.97–0.99) were the factors associated with hypertension. Compared to people without HIV, only WBC, ANC, NLR, and d-NLR were good predictors of hypertension among PLWH.

Conclusion
Our study indicates a notable HIV-status driven association between CBCIS and hypertension, suggesting the use of CBICS as potential biomarkers for hypertension risk with substantial implications for early detection and preventive measures.

Published: November 2024

BACKGROUND: The people with an excessive amount of adipose tissue have elevated levels of free fatty acids (FFA) in the blood, which ultimately leads to disorders of lipid metabolism and insulin resistance, which are the main factors in the development of diabetes mellitus.AIM: To study the content of FFA in blood plasma, as well as their association with body weight in men.MATERIALS AND METHODS: A single-center observational one-stage study was conducted. The sample was formed by a random representative method, comparable by sex and age. The levels of FFA were determined in the blood plasma by high-performance liquid chromatography with mass spectrometry.RESULTS: The study included 250 men. The selected participants were divided into groups according to their body mass index (BMI): Group 1 — 62 people with BMI≤24.9 kg/m2, Group 2 — 101 people with BMI 25.0–29.9 kg/m2, Group 3 — 87 people with BMI≥30.0 kg/m2. Obese men were divided into: Group 4 — 62 people with BMI 30.0–34.9 kg/m2, Group 5 — 19 people with BMI 35.0–39.9 kg/m2, Group 6 — 6 people with BMI≥40.0 kg/m2.The content of docosatetraenoic acid was higher in groups 2 (p=0.002) and 5 (p=0.003), when compared with group 1. The content of gamma-linolenic acid was higher in group 3 than in group 1 (p=0.041). Concentration of oleic; linoleic; dihomo-gamma-linolenic; midic; arachidonic; eicosapentaenoic acids were higher in group 5 than in group 1 (p=0.007, p=0.023, p=0.004, p=0.019, p=0.006, p=0.001, respectively), and also than in group 2 (p=0.006, p=0.017, p=0.007, p=0.007, p=0.008, p=0.001, respectively). The content of nervonic acid is higher in groups 1 (p=0.029) and 2 (p=0.012) than in group 4. Obesity is associated with increased levels of gamma-linolenic (1.030, 1.006–1.056, p=0.015) and eicosapentaenoic acids (1.061, 1.000–1.125, p=0.045), and a decrease in the level of nervonic acid (0.953, 0.913–0.994, p=0.027).CONCLUSION: The FFA levels of blood plasma is significantly different in men with normal body weight and the presence of obesity. The content of oleic, gamma-linolenic, midic, digomo-gamma-linolenic, arachidonic, docosatetraenoic and ­eicosapentaenoic acids was significantly higher in men with grade 2 obesity. An increase in the level of gamma-linolenic and eicosapentaenoic acids, and a decrease in the level of nervonic acid are associated with obesity, regardless of the age.

BACKGROUND: Obesity is a widespread disease associated with serious complications. Obesity is a risk factor for many chronic diseases. The most common type of obesity is polygenic obesity, the pathogenesis of which involves external and internal factors, including genetic ones.AIM: Search and study of the association of variants of the nucleotide sequence rs9939609 of the FTO gene, rs7903146 of the TCF7L2 gene, rs1799883 of the FABP2 gene, rs1800497 of the DRD2 gene, rs17782313 of the MC4R gene with morbid obesity in women.MATERIALS AND METHODS: Study design is case-control study. The morbid obesity group and the control group were formed from the DNA bank of participants of the international project HAPIEE. Genotyping was performed by PCR-RFLP and real-time PCR (TaqMan probes, Applied Biosystems, USA). Statistical analysis was performed in SPSS software using Pearson’s chi-square test, Fisher’s exact two-tailed test with Yates’ correction for continuity. The significance level was used p<0.05.RESULTS: Morbid obesity group included 192 women (mean age 57.02± .16 years) with BMI over 40 kg/m2, control group included 450 women (mean age 55.44±7.41 years) with normal BMI (18.5-24.9 kg/m2). There were no statistically significant differences between the groups in the frequencies of genotypes and alleles rs7903146 of the TCF7L2 gene, rs1799883 of the FABP2 gene, rs1800497 of the DRD2 gene (p>0.05). In the group of morbid obesity, the proportion of carriers of the TT genotype rs9939609 of the FTO gene was statistically significantly lower, and the AT genotype was significantly higher than in the control group (OR=0.579, 95% CI 0.399-0.840, p=0.004; OR=1.408, 95% CI 1.003- 1.976, p=0.047, respectively). The heterozygous TC genotype rs17782313 of the MC4R gene is statistically significantly more common (OR=1.825, 95% CI 1.257-2.652, p=0.002), while the homozygous TT genotype is less common (OR=0.500, 95% CI 0.346-0.723, p<0.001) in group of morbid obesity compared with the control group.CONCLUSION: Heterozygous genotypes of the rs9939609 of the FTO gene (AT) and rs17782313 of the MC4R gene (TC) are risk genotypes; the homozygous genotype TT of the variants is protective for morbid obesity in women. Single nucleotide variants rs7903146 of the TCF7L2 gene, rs1799883 of the FABP2 gene, and rs1800497 of the DRD2 gene are not associated with morbid obesity in women.
Two-year study of the VLF spectrum of heart rate variability in connection with changes in the body composition of girls from 10 to 12 years old
Authors: Filatova O. V. , Shishkina N. A. 
Published: November 2024

BACKGROUND: morphological changes during the pubertal growth spurt can serve as a model for variation in body composition and, in particular, body fat mass (BFM) without any interventions in the human body and associated changes in heart rate variability (HRV).AIM: to study concomitant changes in the VLF spectrum of heart rate variability and body composition in girls during a Two-year study in the age range from 10 to 12 years.MATERIALS AND METHODS: electrocardiography, anthropometry, bioimpedansometry.RESULTS: we conducted a three-year open, uncontrolled, non-randomized study-observation of 60 girls in the age range from 10 to 12 years. This age range made it possible to obtain a wide variation in the rate of increase in body fat mass (BFM%) from negative to positive values. The oscillation power of the very low-frequency component (VLF, ms2 and %) in the HR variability increased statistically significantly with decreasing BFM %. In response to an increase in BMT%, reverse changes were observed. The VLF parameter (ms2) is associated with a positive moderate relationship with the basal metabolic rate (BM) at the age of 10 years (r=0.314, p=0.013). At the same age, the BFM % parameter is associated with an average negative relationship with the BM parameter (r=–0.681, p<0.001).CONCLUSION: in pubertal girls, the change in the composite body composition with a decrease in fat mass is associated with an increase in the absolute (ms2) and relative (%) power of oscillations of the very low-frequency VLF component in HRV.

AIM: To determine the value of urine osmolality when conducting a test with 3% hypertonic sodium chloride solution, which allows for the differential diagnosis of diabetes insipidus (DI) and primary polydipsia (PP).METHODS: An interventional cross-sectional study was conducted at the (Endocrinology Research Center. The study included 90 patients with polyuria-polydipsia syndrome from September 2021 to September 2023. All patients underwent sequential two tests with osmotic stimulation: 3% hypertonic saline infusion test and a water deprivation test. The final diagnosis was established based on the results of a fluid deprivation test, the patient’s anamnestic data (previous operations, diseases of the hypothalamic-pituitary region, the presence of mental illnesses), MRI data (the presence of a hyperintense signal from the posterior pituitary on T1-weighted images, a detected tumor or infiltrative formation of the hypothalamic-pituitary area, presence of Rathke’s pouch cyst).RESULTS: 48 patients with a final diagnosis of DI and 42 with a final diagnosis of PP were analysed. A cut-off point for urine osmolality during infusion test with 3% hypertonic saline was found: values less than or equal to 377 mOsm/kg support the diagnosis of DI, and values higher than 377 mOsm/kg support the diagnosis of PP. The sensitivity of the criterion is 89%, 95% CI (77%; 97%), specificity — 98% (87%; 100%), PPV — 98% (88%; 100%), NPV — 89% (76%; 96%), accuracy 93% (86%; 98%).CONCLUSION: The proposed criterion for differential diagnosis has comparable diagnostic accuracy in relation to the differential diagnosis of DI and PP, while the safety of the test may be higher.
