Longitudinal Alterations in the Control of Lateral Center of Mass Movement During Walking in a Patient With Unilateral Transtibial Amputation: A Case Study.

This study assessed longitudinal changes in the control of the center of mass (CoM) in the lateral direction through gait reacquisition in an individual with unilateral transtibial amputation (UTTA). We examined a male patient with UTTA who could walk on a parallel bar. The marker trajectories and ground reaction forces were measured every two weeks (total: four times) using an optical motion capture system and force plates. After two measurements, the samples were collected without a parallel bar. Subsequently, we evaluated the CoM movement and its segmental coordination through uncontrolled manifold (UCM) analysis. After the second measurement, the walking speed and step length increased. The lateral CoM movements gradually increased toward the prosthetic side until the third measurement. In the fourth measurement, the CoM movement towards the prosthetic side was the smallest and closest to the intact side at the end of the stance phase. In addition, segmental coordination improved significantly. Enhanced gait performance delayed the improvement of segmental coordination for CoM movement in the lateral direction.

Early-onset and uncontrolled diabetes mellitus factors correlate with complications of Peyronie's disease.

BACKGROUND: Peyronie's disease (PD) is a connective tissue disorder that affects the penis and is characterized by abnormal collagen structure in the penile tunica albuginea, resulting in plaque formation and penile deformity. PD's overall prevalence is estimated at 3.2% to 8.9%, with rates as high as 20.3% among men with type 2 diabetes mellitus (DM). However, the characteristics of DM associated with PD complications remain unclear. AIM: To explore clinical associations between DM characteristics and PD complications. METHODS: We conducted a retrospective analysis of patients with DM and PD who presented at our institution between 2007 and 2022. We examined patients' clinical histories, DM- and PD-related clinical parameters, and complications. Penile deformities were assessed through physical examination, photographs, and penile Doppler ultrasound. Patients were categorized into subgroups based on age of DM onset: early (<45 years), average (45-65 years), and late (>65 years). OUTCOMES: Outcomes included effects of DM characteristics on PD development, progression, and severity. RESULTS: In total, 197 patients were included in the evaluation. Early-onset diabetes and elevated hemoglobin A1c (HbA1c) levels exhibited significant correlations with the early development of PD (ρ = 0.66, P < .001, and ρ = -0.24, P < .001, respectively). Furthermore, having DM at an early age was associated with the occurrence of penile plaque (ρ = -0.18, P = .03), and there were no significant differences in plaque dimensions (ρ = -0.29, P = .053). A rise in HbA1c levels after the initial PD diagnosis displayed positive correlations with the formation of penile plaque (ρ = 0.22, P < .006). CLINICAL IMPLICATIONS: These findings emphasize the need for comprehensive assessments and personalized treatment strategies for individuals with DM and PD. Enhanced management approaches can improve outcomes for those facing both challenges. STRENGTHS AND LIMITATIONS: Limitations include the single-site retrospective design with potential selection bias, inaccuracies in medical record data, and challenges in controlling confounding variables. CONCLUSIONS: This study highlights that early-onset diabetes and poor diabetes control, as indicated by a subsequent rise in HbA1c levels following PD diagnosis, are significantly correlated with the onset and severity of PD. Revealing the mechanisms behind these findings will help us develop better management strategies for individuals with DM and PD.

Unhealthy habits and comorbidities associated with uncontrolled asthma in young people.

INTRODUCTION: Asthma is a chronic inflammatory disease of the lower airways that affects more than 260 million people worldwide and has been related to more than 460,000 deaths a year. It is estimated that in 60% of asthma cases, the symptoms are not adequately controlled. The objective of this study was to determine the association between some comorbidities, habits, and health risk behaviors with uncontrolled asthma in a sample of young people with asthma. METHODS: Through a cross-sectional study, data from 1,078 young people aged 17 to 19 years were analyzed. Information was collected through physical examination, direct questioning, and the application of a self-administered questionnaire. RESULTS: In the group of young people with asthma, the prevalence of uncontrolled asthma was 20.6%, of which 53.8% were women, 76.9% suffered from rhinitis, 46.2% were overweight and 23.1% were obese. In the group of young with uncontrolled asthma, gingivitis was detected in 53.8% and alcohol consumption in 84.6%. Logistic regression analysis showed a significant association between allergic rhinitis, gingivitis, carbohydrate intake, alcohol consumption, overweight, and obesity with uncontrolled asthma. CONCLUSIONS: Parents and members of the health team need to identify on time the risk factors associated with uncontrolled asthma in young people with asthma to limit its development and the negative effects it generates. The results of this study should be used to strengthen programs that promote the comprehensive health of adolescents.

Asthma Control and Associated Factors Among Children with Current Asthma - Findings from the 2019 Child Behavioral Risk Factor Surveillance System - Asthma Call-Back Survey.

Purpose: This study aimed to determine the prevalence and correlates of uncontrolled asthma among children with current asthma in four US states. We also determined the rates and correlates of asthma-related hospitalization, urgent care center (UCC), or emergency department (ED) visits. Participants and Methods: We analyzed the 2019 Behavioral Risk Factor Surveillance Survey (BRFSS) Asthma Call-back Survey (ACBS) datasets. Asthma control status was classified as well-controlled or uncontrolled asthma based on day- and night-time asthma symptoms, activity limitation or use of rescue medications. Multivariable logistic regression models were used to identify the correlates of uncontrolled asthma and asthma-related hospitalization or UCC/ED visits. Results: Among 249 children with current asthma, 55.1% had uncontrolled asthma while 40% reported asthma-related hospitalization or UCC/ED visits in the past year. Non-Hispanic ethnicity, ages of 0-9 and 15-17 years, household income <$25,000, and not having a flu vaccination had higher odds of uncontrolled asthma. Conversely, asthma self-management education and households with two children compared to one were positively associated with uncontrolled asthma. For healthcare utilization, male and non-Hispanic children, along with those from households earning <$25,000 exhibited higher odds of asthma-related hospitalization and UCC/ED visits. Conclusion: Uncontrolled asthma and asthma-related visits to UCC/ED and hospitalization are common among children with current asthma. These outcomes are influenced by low household income and male sex, among other factors which call for multi-faceted interventions by healthcare providers and policymakers. Targeted strategies to effectively manage asthma and reduce the need for emergency healthcare services are recommended.

Mapping of uncontrolled dumpsites in arid regions through remote sensing and image processing.

Due to increased urbanization, the development of new areas, construction of new houses and buildings and uncontrolled dumpsites (UDSs) are becoming a challenge facing local authorities in Saudi Arabia. UDSs pose health risks to the public, potentially deteriorating the environment around them and reducing the value of ongoing development areas. The local municipalities rely on field surveys and citizen reports. This can be inefficient because UDSs are often discovered too late, and remediating them can be costly. This study aimed to assess the conditions of UDSs in two cities in the Eastern Province of Saudi Arabia, Dammam and Hafer Al-Batin, using satellite image classification assessment techniques. The assessment included mapping the UDS locations and studying the spectral reflectance of the materials found in these dumpsites. The study provided a mapping of 62 UDS locations totalling around 13.01 km2 in the broader study area. UDS detections using remote sensing were followed by ground truthing and in situ measurements using a spectroradiometer. In addition, the spectral reflectance of 21 commonly deposited UDS materials was studied, and a spectral library was created for these materials for future use by local authorities.

Analysis of risk factors and clinical implications for diabetes in first-degree relatives in the northeastern region of China.

Background: The prevalence of diabetes has risen fast with a considerable weighted prevalence of undiagnosed diabetes or uncontrolled diabetes. Then it becomes more necessary to timely screen out and monitor high-risk populations who are likely to be ignored during the COVID-19 pandemic. To classify and find the common risks of undiagnosed diabetes and uncontrolled diabetes, it's beneficial to put specific risk control measures into effect for comprehensive primary care. Especially, there is a need for accurate yet accessible prediction models. Objective: Based on a cross-sectional study and secondary analysis on the health examination held in Changchun City (2016), we aimed to evaluate the factors associated with hyperglycemia, analyze the management status of T2DM, and determine the best cutoff value of incidence of diabetes in the first-degree relatives to suggest the necessity of early diagnosis of diabetes after first screening. Results: A total of 5658 volunteers were analyzed. Prevalence of T2DM and impaired fasting glucose were 8.4% (n=477) and 11.5% (n=648), respectively. There were 925 participants (16.3%) with a family history of T2DM in their first-degree relatives. Multivariable analysis demonstrated that family history was associated with hyperglycemia. Among the 477 patients with T2DM, 40.9% had not been previously diagnosed. The predictive equation was calculated with the following logistic regression parameters with 0.71 (95% CI: 0.67-0.76) of the area under the ROC curve, 64.0% of sensitivity and 29% of specificity (P < 0.001): P = \frac{1}{1 + e^{-z}}, where z = -3.08 + [0.89 (Family history-group) + 0.69 (age-group)+ 0.25 (BMI-group)]. Positive family history was associated with the diagnosis of T2DM, but not glucose level in the diagnosed patients. The best cutoff value of incidence of diabetes in the first-degree relatives was 9.55% (P < 0.001). Conclusions: Family history of diabetes was independently associated with glucose dysfunction. Classification by the first-degree relatives with diabetes is prominent for targeting high-risk population. Meanwhile, positive family history of diabetes was associated with diabetes being diagnosed rather than the glycemic control in patients who had been diagnosed. It's necessary to emphasize the linkage between early diagnosis and positive family history for high proportions of undiagnosed T2DM.

Quantifying Changes in Dexterity as a Result of Piano Training in People with Parkinson's Disease.

People with Parkinson's disease often show deficits in dexterity, which, in turn, can lead to limitations in performing activities of daily life. Previous studies have suggested that training in playing the piano may improve or prevent a decline in dexterity in this population. In this pilot study, we tested three participants on a six-week, custom, piano-based training protocol, and quantified dexterity before and after the intervention using a sensor-enabled version of the nine-hole peg test, the box and block test, a test of finger synergies using unidimensional force sensors, and the Quantitative Digitography test using a digital piano, as well as selected relevant items from the motor parts of the MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and the Parkinson's Disease Questionnaire (PDQ-39) quality of life questionnaire. The participants showed improved dexterity following the training program in several of the measures used. This pilot study proposes measures that can track changes in dexterity as a result of practice in people with Parkinson's disease and describes a potential protocol that needs to be tested in a larger cohort.

Adherence to inhaled corticosteroid therapy and treatment escalation in the Swedish adult asthma population.

BACKGROUND: Patients with uncontrolled asthma should be evaluated for medication adherence. This study aimed to identify characteristics associated with poor adherence to inhaled corticosteroids (ICS) and to explore adherence prior to treatment escalation. METHODS: This nationwide longitudinal cohort study included adult asthma patients (n = 30880) with a healthcare visit including Asthma Control Test (ACT) and registered in the Swedish National Airway Register between 1 July 2017 and 28 February 2019 (index date). Patient data was crosslinked to other national registers. Treatment steps two years pre- and one year post-index, were identified by prescribed drugs. Poor adherence was defined as Medication Possession Ratio <80 %. RESULTS: Poor adherence was identified in 73 % of patients in treatment steps 2-5, where of 35 % had uncontrolled asthma (ACT≤19). In adjusted models, poor adherence was associated with better disease control; ACT≤19 (OR 0.78, 95 % CI 0.71-0.84), short-acting ß2-agonist (SABA) overuse (0.69, 0.61-0.79) and exacerbations (0.79, 0.70-0.89) in steps 2-3. Among patients with uncontrolled asthma, poor adherence was associated with SABA overuse (1.71, 1.50-1.95), exacerbations (1.29, 1.15-1.46), current smoking (1.38, 1.21-1.57) and inversely associated with asthma management education (0.85, 0.78-0.93. Similar results were observed in steps 4-5. When investigating post-index treatment, 53 % remained stationary, 30 % stepped down and 17 % escalated treatment. Prior to escalation, 49 % had poor adherence. CONCLUSIONS: Poor ICS adherence was associated with better asthma control. Among uncontrolled patients, poor adherence was associated with SABA overuse and exacerbations. Our result highlights the importance of asthma management education to improve adherence in uncontrolled patients.

The Amount and Pattern of Reciprocal Compensations Predict Performance Stability in a Visually Guided Finger Force Production Task.

Previous work suggests that synergistic activity among motor elements implicated in force production tasks underlies enhanced performance stability associated with visual feedback. A hallmark of synergistic activity is reciprocal compensation, that is, covariation in the states of motor elements that stabilizes critical performance variables. The present study examined if characteristics of reciprocal compensation are indicators of individuals' capacity to respond adaptively to variations in the resolution of visual feedback about criterion performance. Twenty healthy adults (19.25 ± 1.25 years; 15 females and five males) pressed two sensors with their index fingers to produce a total target force equivalent to 20% of their maximal voluntary contraction under nine conditions that differed in the spatial resolution of real-time feedback about their performance. By combining within-trial uncontrolled manifold and sample entropy analyses, we quantified the amount and degree of irregularity (i.e., non-repetitiveness) of reciprocal compensations over time. We found a U-shaped relationship between performance stability and gain. Importantly, this relationship was moderated by the degree of irregularity of reciprocal compensation. Lower irregularity in reciprocal compensation patterns was related to individuals' capacity to maintain (or minimize losses in) performance under changes in feedback resolution. Results invite future investigation into how interindividual variations in reciprocal compensation patterns relate to differences in control strategies supporting adaptive responses in complex, visually guided motor tasks.

Treatable traits and exacerbation risk in patients with uncontrolled asthma prescribed GINA step 1-3 treatment: A nationwide asthma cohort study.

BACKGROUND AND OBJECTIVE: Uncontrolled asthma in patients treated for mild/moderate disease could be caused by non-pulmonary treatable traits (TTs) that affect asthma control negatively. We aimed to identify demographic characteristics, behavioural (smoking) and extrapulmonary (obesity, comorbidities) TTs and the risk for future exacerbations among patients with uncontrolled asthma prescribed step 1-3 treatment according to the Global Initiative for Asthma (GINA). METHODS: Twenty-eight thousand five hundred eighty-four asthma patients (≥18 y) with a registration in the Swedish National Airway Register between 2017 and 2019 were included (index-date). The database was linked to other national registers to obtain information on prescribed drugs 2-years pre-index and exacerbations 1-year post-index. Asthma treatment was classified into step 1-3 or 4-5, and uncontrolled asthma was defined based on symptom control, exacerbations and lung function. RESULTS: GINA step 1-3 included 17,318 patients, of which 9586 (55%) were uncontrolled (UCA 1-3). In adjusted analyses, UCA 1-3 was associated with female sex (OR 1.34, 95% CI 1.27-1.41), older age (1.00, 1.00-1.00), primary education (1.30, 1.20-1.40) and secondary education (1.19, 1.12-1.26), and TTs such as smoking (1.25, 1.15-1.36), obesity (1.23, 1.15-1.32), cardiovascular disease (1.12, 1.06-1.20) and depression/anxiety (1.13, 1.06-1.21). Furthermore, UCA 1-3 was associated with future exacerbations; oral corticosteroids (1.90, 1.74-2.09) and asthma hospitalization (2.55, 2.17-3.00), respectively, also when adjusted for treatment step 4-5. CONCLUSION: Over 50% of patients treated for mild/moderate asthma had an uncontrolled disease. Assessing and managing of TTs such as smoking, obesity and comorbidities should be conducted in a holistic manner, as these patients have an increased risk for future exacerbations.

Three Levels of Neural Control Contributing to Performance-stabilizing Synergies in Multi-finger Tasks.

We tested a hypothesis on force-stabilizing synergies during four-finger accurate force production at three levels: (1) The level of the reciprocal and coactivation commands, estimated as the referent coordinate and apparent stiffness of all four fingers combined; (2) The level of individual finger forces; and (3) The level of firing of individual motor units (MU). Young, healthy participants performed accurate four-finger force production at a comfortable, non-fatiguing level under visual feedback on the total force magnitude. Mechanical reflections of the reciprocal and coactivation commands were estimated using small, smooth finger perturbations applied by the "inverse piano" device. Firing frequencies of motor units in the flexor digitorum superficialis (FDS) and extensor digitorum communis (EDC) were estimated using surface recording. Principal component analysis was used to identify robust MU groups (MU-modes) with parallel changes in the firing frequency. The framework of the uncontrolled manifold hypothesis was used to compute synergy indices in the spaces of referent coordinate and apparent stiffness, finger forces, and MU-mode magnitudes. Force-stabilizing synergies were seen at all three levels. They were present in the MU-mode spaces defined for MUs in FDS, in EDC, and pooled over both muscles. No effects of hand dominance were seen. The synergy indices defined at different levels of analysis showed no correlations across the participants. The findings are interpreted within the theory of control with spatial referent coordinates for the effectors. We conclude that force stabilization gets contributions from three levels of neural control, likely associated with cortical, subcortical, and spinal circuitry.

Potential Molecular Markers for Cholecystic Inflammation-Induced Carcinogenesis Based on RNA-Seq Gene Screening.

BACKGROUND: Uncontrolled inflammation plays an important role in the initiation and progression of tumors. The repeated circulation and continuous stimulation of gallbladder epithelium caused by gallstones is an important risk factor for gallbladder cancer. METHODS: To study pathogenesis, samples were collected for chronic cholecystitis caused by gallstones and early and advanced gallbladder cancer with gallstones and subjected to RNA-seq analysis. Gene Ontology and Kyoto Gene and Genome Encyclopedia analyses were used to elucidate the protein-protein interaction network and identify differentially expressed genes. RESULTS: Nine potential molecular markers, VTN, CHAD, AKR1C4, ABCC2, AOX1, ADH1A, ADH1C, PLA2G2A, and CYP4F3, with elevated expression gradients in cholecystitis and early and advanced gallbladder cancer, were identified. Using qPCR and immunohistochemistry on clinical tissues, we confirmed three factors, VTN, CYP4F3, and AOX1, to be worthy of further research. To demonstrate that these three genes are potential molecular markers for gallbladder cancer, their cellular biological functions were confirmed in gallbladder cancer cell lines through siRNA transfection. CONCLUSION: The potential molecular markers CYP4F3, VTN, and AOX1 for cholecystitis and different stages of gallbladder cancer were identified. Further studies on differentially expressed genes vital in gallbladder cancer progression can help provide potential targets for the early diagnosis and treatment of gallbladder cancer.

White Coat Hypertension & Cardiovascular Outcomes.

PURPOSE OF REVIEW: This review aims to inform the reader of the complexity of blood pressure responses when comparing blood pressure measured in the medical environment to that outside the medical environment. In addition, we summarize what is known about current predictors of white coat hypertension, reevaluate the relationship of white coat hypertension to cardiovascular outcomes, and provide some clinical guidance on management. RECENT FINDINGS: Differences in outcomes exist when white coat effect occurs in unmedicated people versus the white coat effects in those on antihypertensive therapy. White coat hypertension is relatively common, carries a small but definite increase in cardiovascular risk, and is prone to conversion to sustained hypertension. Future research will hopefully tease out the roles of ancillary findings that characterize a white coat hypertensive (like modest elevations in creatinine, glucose and triglycerides) in the elevated cardiovascular risk, and test the effectiveness of mitigation strategies in these patients.

The Association Between Vitamin D Deficiency and the Level of Fasting C Peptide Among Patients With Uncontrolled Type 2 Diabetes Mellitus: A Retrospective Cohort Study.

This study investigates the relationship between vitamin D deficiency and uncontrolled type 2 diabetes mellitus (T2DM) indicated by elevated glycosylated hemoglobin (HbA1c) levels, alongside assessing the association between fasting C peptide levels and uncontrolled T2DM, considering their roles in ß-cell function and insulin secretion. The study employs a cohort design, selecting individuals diagnosed with T2DM aged 18 years or older with baseline data on vitamin D, fasting C peptide, and HbA1c. Data were collected through electronic medical records and follow-up assessments at regular intervals. Binary logistic regression analyses were conducted to explore associations between exposure variables and uncontrolled T2DM. Significant associations were observed between vitamin D and C peptide levels with uncontrolled diabetes, with coefficients of -0.097 and -0.222, respectively. Higher vitamin D and C peptide levels are linked to a decreased likelihood of uncontrolled diabetes. In conclusion, there is a potential connection between vitamin D levels, C peptide levels, and uncontrolled diabetes mellitus (HbA1C > 7%), while higher levels of both vitamin D and C peptide appeared to correlate with a decreased likelihood of uncontrolled diabetes.

Association between pulse pressure and carotid plaques in old adults with uncontrolled hypertension: results from a community-based screening in Hangzhou, China.

BACKGROUND: There is a broad pulse pressure (PP) and a high prevalence of carotid plaques in old adults. Previous studies have indicated that PP is strongly associated with carotid plaque formation. This study aimed to explore this association in old adults with uncontrolled hypertension. METHODS: 1371 hypertensive patients aged ≥ 60 years with uncontrolled hypertension were enrolled in a community-based screening in Hangzhou, China. Carotid plaques were assessed using ultrasonography. Logistic regression models were used to estimate the association between PP and carotid plaques by odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Carotid plaques were detected in 639 (46.6%) of subjects. Multiple plaques were found in 408 (63.8%) and soft plaques in 218 (34.1%). Elevated PP was associated with a high prevalence of carotid plaques. After adjusting for traditional risk factors, compared to patients within the lowest tertile of PP, those within the highest tertiles had an increased risk of carotid plaques (OR 2.061, CI 1.547-2.745). For each 1-SD increase, the risk increased by 40.1% (OR 1.401, CI 1.237-1.587). There was a nonlinear association between PP and carotid plaques (P nonlinearity = 0.039). The risk increased rapidly after the predicted PP level reached around 60 mmHg. The associations were stronger among participants with multiple and soft plaques. CONCLUSIONS: Our findings suggested that PP was independently associated with carotid plaques in old adults with uncontrolled hypertension who have an increased risk of atherosclerosis.

Asthma control in the United States: relationships between short-acting ß2-agonist and systemic corticosteroid use.

BACKGROUND: Asthma control assessment is based on impairment (current symptoms) and risk (exacerbation history). OBJECTIVE: To understand the extent of uncontrolled asthma, we assessed relationships between prescription fills for systemic corticosteroids (SCS) and short-acting ß2-agonists (SABA) as risk and impairment markers, respectively. METHODS: Annual SCS and SABA fills among US patients with asthma were evaluated by a retrospective analysis of IQVIA Longitudinal Access and Adjudication Data. Patient severity was assigned based on GINA step-therapy level. Exacerbations were evaluated by SCS fills within 12 months of a first asthma prescription fill. Uncontrolled asthma was defined as ≥2 SCS and/or ≥3 SABA fills annually. Individual patient relationships between SCS and SABA fills were assessed by Pearson's correlation coefficient. RESULTS: 4,506,527 patients were included: 15% had ≥2 SCS fills, 29% had ≥3 SABA fills, 37% fulfilled either or both criteria. If only SCS were assessed, 22% treated as mild-to-moderate and 27% as severe asthma would have been misclassified as controlled. If only SABA use was evaluated, 8% treated as mild-to-moderate and 11% as severe asthma would have been misclassified. Overall, 81% of uncontrolled asthma occurred in patients treated for mild-to-moderate disease. Among patients with ≥2 SCS fills, mean SABA fills were 2.9; the correlation between SCS and SABA fills per patient was significant but weak (r=0.18; p<0.001). CONCLUSION: High symptom burden and SCS exposures are not limited to severe asthma but are also characteristic in patients treated for mild-to-moderate disease. Both impairment and risk assessments are required to understand the full extent of uncontrolled asthma across disease severities.

Eruptive xanthoma as a warning sign of uncontrolled hypertriglyceridemia presenting with acute pancreatitis and uncontrolled type II diabetes mellitus: A case report.

Key Clinical Message: Managing diabetic ketoacidosis (DKA) in individuals with severe dyslipidemia necessitates a comprehensive approach. While rehydration and continuous insulin infusion are fundamental components of DKA management due to the underlying insulin deficiency, the presence of severe hyperlipidemia with eruptive xanthomas warrants additional consideration. Early initiation of lipid-lowering agents can expedite the resolution of cutaneous lesions and substantially mitigate the risk of severe complications such as pancreatitis, along with attenuating long-term cardiovascular risks. Abstract: Xanthomas are the benign lesions which are generated by localized lipid deposits in the skin, tendons, and subcutaneous tissue. They appear clinically as yellowish papules, nodules, or plaques. Acute pancreatitis and eruptive xanthomas can occur as complications of hyperlipidemia. Uncontrolled diabetes mellitus in one of the risk factors for hypertriglyceridemia. Early recognition and treatment of the eruptive xanthomatosis as a warning sign of hypertriglyceridemia can decrease the morbidity and mortality due to acute pancreatitis. Here, we discuss a case of 37-years old female patient with uncontrolled type II diabetes mellitus presented with acute pancreatitis and eruptive xanthomas as result of raised triglycerides and uncontrolled diabetes.

A game-theoretic approach for modelling pedestrian-vehicle conflict resolutions in uncontrolled traffic environments.

The interactions of motorised vehicles with pedestrians have always been a concern in traffic safety. The major threat to pedestrians comes from the high level of interactions imposed in uncontrolled traffic environments, where road users have to compete over the right of way. In the absence of traffic management and control systems in such traffic environments, road users have to negotiate the right of way while avoiding conflict. Furthermore, the high level of movement freedom and agility of pedestrians, as one of the interactive parties, can lead to exposing unpredictable behaviour on the road. Traffic interactions in uncontrolled mixed traffic environments will become more challenging by fully/partially automated driving systems' deployment, where the intentions and decisions of interacting agents must be predicted/detected to avoid conflict and improve traffic safety and efficiency. This study aims to formulate a game-theoretic approach to model pedestrian interactions with passenger cars and light vehicles (two-wheel and three-wheel vehicles) in uncontrolled traffic settings. The proposed models employ the most influencing factors in the road user's decision and choice of strategy to predict their movements and conflict resolution strategies in traffic interactions. The models are applied to two data sets of video recordings collected in a shared space in Hamburg and a mid-block crossing area in Surat, India, including the interactions of pedestrians with passenger cars and light vehicles, respectively. The models are calibrated using the identified conflicts between users and their conflict resolution strategies in the data sets. The proposed models indicate satisfactory performances considering the stochastic behaviour of road users - particularly in the mid-block crossing area in India - and have the potential to be used as a behavioural model for automated driving systems.

The effect of motor experience on knee stability and inter-joint coordination when cutting at different angles.

BACKGROUND: Most studies on cutting have focused on the biomechanics of the knee and lower-limb muscle activation characteristics, with less consideration given to the influence of motor experience on control strategies at the joint level. This study aimed to investigate the differences in knee stability and inter-joint coordination between high- and low-level athletes when cutting at different angles. METHODS: A Vicon motion capture system and a Kistler force table were used to obtain kinematic and ground reaction force data during cutting. Joint dynamic stiffness and vector coding were used to assess knee stability and inter-joint coordination. Uncontrolled manifold analysis was used to clarify whether there was synergy among lower-limb joints to maintain postural stability during cutting. RESULTS: During the load acceptance phase, skilled subjects had the smallest joint stiffness at 90° compared with novice subjects (P < 0.05). Compared with novice subjects, skilled subjects had smaller knee-hip ellipse areas at 90° and 135° (P < 0.05), but larger knee-ankle ellipse areas at 135° (P < 0.05). The synergy index in load acceptance was significantly higher (P < 0.05) for skilled subjects at 90° and 135°. CONCLUSIONS: Advanced subjects can adjust joint control strategies to adapt to the demands of large-angle cutting on the change of direction. Advanced subjects can reduce knee stability for greater flexibility during cutting compared with novice subjects. By increasing the degree of synergy among the lower-limb joints, advanced athletes can maintain high postural stability.

The causal associations between interoception, self-regulation, non-purposeful eating behaviors, and weight status in college women: a longitudinal cross-lagged model analysis.

AIMS: Excessive weight gain has led to increased obesity and mortality risk among college students. Issues with maintaining a healthy weight may be attributed to poor internal awareness and unhealthy eating behaviors. The study's purpose was to determine the longitudinal effects among interoception, self-regulation, nonpurposeful eating behaviors, and weight status (BMI) among college women. METHODS: Data from 103 females were collected via Qualtrics over 3 timepoints (T1, T2, T3) during an academic semester. Repeated measures ANOVA and cross-lagged model analyses were used. Significant changes were found in interoceptive responsiveness, external, and uncontrolled eating throughout 3 timepoints. RESULTS: Longitudinally, significant causal effects were found among the study measures. Among all models, higher interoceptive responsiveness (T1) predicted increased self-regulation (T2). Higher non-purposeful eating behaviors (T1) predicted reduced self-regulation (T2). Higher BMI (T1) predicted reduced non-purposeful eating behaviors (T2), however higher BMI (T2) predicted increased non-purposeful eating (T3) and reduced interoceptive responsiveness (T3). Significant causal effects were found within each non-purposeful eating behavior models. CONCLUSION: Overall, the research study provided foundational evidence of the importance of self-regulatory skills to help prevent unhealthy eating behaviors and increased weight status in college women. Future interventions educating college women to become more internally aware and better self-regulate are needed.
