Dual-task gait has prognostic value for cognitive decline in Parkinson’s disease

IntroductionCognitive decline frequently occurs in individuals with Parkinson’s disease (PD), but the clinical methods to predict the onset of cognitive changes are limited. Given preliminary evidence of the link between gait and cognition, the purpose of this study was to determine if dual task (DT) gait was related to declines in cognition over two years in PD. MethodsA retrospective two-year longitudinal study of 48 individuals with PD using data from the Parkinson’s Progression Markers Initiative of the Michael J. Fox Foundation. The following data were extracted at baseline: spatiotemporal gait (during single and DT), demographics (age, sex), PD disease duration (time since diagnosis), motor function (Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS)), and cognition (Montreal Cognitive Assessment (MoCA)), with MoCA scores also extracted after two years. ResultsA binomial logistic regression was conducted, with all covariates (above) in block 1 and DT effect (DTE) of gait characteristics in block 2 entered in a stepwise fashion. The final model was statistically significant (χ2(6) = 23.20, p < 0.001) and correctly classified 78.7 % of participants by cognitive status after two years. Only DTE of arm swing asymmetry (ASA) (p = 0.030) was included in block 2 such that a 1 % decline in DTE resulted in 1.6 % increased odds of cognitive decline. ConclusionsIndividuals with greater change in arm swing asymmetry from single to DT gait may be more likely to experience a decline in cognition within two years. These results suggested that reduced automaticity or poor utilization of attentional resources may be indicative of subtle changes in cognition and indicate that DT paradigms may hold promise as a marker of future cognitive decline.

Serum γ-glutamyltransferase levels and obesity status changes the risk of prehypertension in Chinese adults

ObjectiveIt’s well known that γ-Glutamyltransferase (γ-GGT) and obesity plays an important role in the development of preHT. However, the effect of γ-GGT on preHT in populations with different obesity status remains unclear. MethodsFrom February 2014 to January 2018, a total of 20,368 participants were enrolled in this study after excluding those with hypertension and liver diseases. Fasting blood samples were collected to measure γ-GGT and blood lipid levels and glucose indices. Demographic andclinical parameters such assex, age, height, weight, neck circumference (NC), waist circumference (WC), hip circumference (HC), and body fat ratio (BFR); and information on smoking and alcohol consumption were collected by trained medical professionals. ResultsParticipants were divided into three groups based on obesity status. The prevalence of preHT was 83.5 % in the obesity group was higher than that in the overweight group (58.9 %) and the normal group (47.1 %). γ-GGT in different categories of obesity indices were significantly different, and higher obesity indices were found with higher γ-GGT levels. The interaction of γ-GGT and obesity indices such as NC, WC, HC, and BFR on the prevalence of preHT was significant (P = 0.028, 0.002, 0.007, and 0.034, respectively). Serum γ-GGT was found to be positively associated with preHT in participants with normal and overweight body mass indices. ConclusionOur results indicate that γ-GGT is a risk factor for preHT in participants who are nonobese, and that the obesity indices NC, WC, HC, BFR, and γ-GGT were contributing factors in increasing the risk of preHT.

Relationships among age, motivation, and exercise among women Veterans

Physical activity (PA) and exercise are central to maintaining health, however research has shown steep declines in PA and exercise among women Veterans as they age. Though motivation may be an important contributor to initiating and sustaining exercise that may change across the lifespan, little is known about exercise motivation and its relation to age and exercise behavior among women Veterans. This cross-sectional study sought to describe exercise motivations, examine relationships among exercise motivations and age, and explore the degree to which age and motivation predict self-reported exercise behavior among women Veterans. We conducted a secondary data analysis from a regional mail survey of 197 women Veterans (mean age = 51; SD = 10.5) enrolled in Veterans Health Administration primary care in a northeastern region (N = 180 in analysis). Measures included demographics (age, body mass index), self-reported exercise motivation, and an estimate of average weekly exercise. Participants endorsed multiple motivators for exercise, most prominently fitness and health management. Age was significantly negatively related to amount of exercise and with socializing as an exercise motivation. After accounting for body mass index, age was a significant predictor of exercise behavior, and exercise motivations accounted for an additional 7.3% of variance in self-reported weekly exercise. Our results suggest that although motivation is a potentially important predictor of exercise, factors beyond motivation may better predict exercise in women Veterans. Further research is needed on personal and practical facilitators and barriers to exercise in this population.

Are Cellular Bone Matrix Allografts a Viable Option for Mandibular Tissue Engineering and Reconstruction?

BackgroundTraditional mandibular reconstruction has relied on the use of vascularized and non-vascularized autografts. The use of allografts and tissue engineering modalities has risen as an alternative. PurposeThe purpose of this study was to determine the success of a cellular bone matrix (CBM) allograft composed of lineage committed bone forming cells for mandibular tissue engineering and reconstruction. Study design, setting, sampleA retrospective cohort study was implemented using data from subjects treated with a CBM at the University of Louisville from 2019 to 2023. Subjects were excluded if they were not treated with a CBM, data were not complete, or postoperative follow-up time was less than 3 months. Predictor variablesThe predictor variables were composed of heterogenous variables grouped into the following categories: demographics (age, sex), medical history (history of penicillin (PCN) allergy, history of diabetes mellitus (DM) and tobacco use), etiology (benign tumor, ballistic trauma, non-ballistic trauma, odontogenic cyst, osteomyelitis/MRONJ), mandibular resection length (cm) and type (marginal, segmental), delayed vs immediate reconstruction, and whether an autograft (proximal tibia, TBG) with platelet rich fibrin (PRF) was used in combination with the CBM. Main outcome variableThe primary outcome variable was graft success (yes or no). Success was defined as bony union and defect fill (demonstrated on panoramic radiograph) and mandibular stability (based on postoperative clinical examination at 3 months). CovariatesNot applicable. AnalysesDescriptive statistics were calculated for each variable. To measure the associations between the risk factors and graft success, Fisher’s exact test for categorical variables and the Wilcoxon rank sum test for numeric data were used. A p-value of <0.05 was considered significant. ResultsThe sample included 38 subjects. The median age of all subjects was 46 (IQR 32.6) years. Overall, 28 (73.7%) cases were successful. Subjects with a reported PCN allergy or a history of DM had significantly lower success (2, 7.1% with PCN allergy or DM) compared to those who did not (p = 0.008, PCN allergy; p = 0.03, DM). Conclusions and RelevanceThis is the largest case series of CBM based mandibular reconstruction relative to the available maxillofacial surgery literature. The clinician should consider confirmation of penicillin allergy so penicillin-type antibiotics can be used. CBMs may be an alternative to autografts.

Predictors of Concussion Symptom Reporting Intention among Collegiate Athletes.

Underreporting of concussion symptoms in college athletics presents a challenge for sports medicine clinicians in evaluating and diagnosing such injuries. Some athletes do not report concussion symptoms because they do not recognize that they have a brain injury, however many athletes intentionally withhold symptoms to avoid removal from sport participation. To examine individual factors that influence college athletes' intentions to report concussion symptoms. Cross-sectional study. Collegiate athletics. 2,649 student-athletes from 23 sports, across 22 colleges/universities. The primary outcome was intention to report concussion symptoms. Predictor variables included demographics (age, race/ethnicity, sex, sport type, number of years in sport, number of previous concussions, and perceived concussion symptom knowledge), athletic identity, attitudes toward symptom reporting, perceived social pressure (injunctive and descriptive norms), and perceived behavioral control (capacity and autonomy). Hierarchical ordinary least squares regression revealed positive effects of attitude (b = .063; P = .005), descriptive norms (b = .131; P < .001), injunctive norms (b = .107; P < .001), and capacity (b = .196; P < .001) on intention to report symptoms. Athletic identity and participation in collision sports had small negative indirect effects on intention, while perceived concussion knowledge had a small positive indirect effect. The full regression model explained 14.24% of the variance in concussion reporting intention. These findings may help clinicians develop more focused interventions that address key social and individual determinants of underreporting, including attitude, injunctive and descriptive norms, and capacity to report. Athletic identity, sport type, and perceived understanding of concussion symptoms also influence reporting intention to a lesser extent. Previous research in this area has often failed to address a diverse population of college-age athletes from different sports and NCAA divisions.

Emerging N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) and 6PPD quinone in paired human plasma and urine from Tianjin, China: Preliminary assessment with demographic factors

With increasing concerns about N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD) and 6PPD-quinone (6PPD-Q), relevant environmental investigations and toxicological research have sprung up in recent years. However, limited information could be found for human body burden assessment. This work collected and analyzed 200 samples consisting of paired urine and plasma samples from participants (50 male and 50 female) in Tianjin, China. Low detection frequencies (DF, <15 %) were found except for urinary 6PPD-Q (86 %), which suggested the poor residue tendency of 6PPD and 6PPD-Q in blood. The low DFs also lead to no substantial association between two chemicals. Data analysis based on urinary 6PPD-Q showed a significant difference between males and females (p < 0.05). No significant correlation was found for other demographic factors (Body Mass Index (BMI), age, drinking, and smoking). The mean values of daily excretion (ng/kg bw/day) calculated using urinary 6PPD-Q for females and males were 7.381 ng/kg bw/day (female) and 3.360 ng/kg bw/day (male), and apparently female suffered higher daily exposure. Further analysis with daily excretion and ALT (alanine aminotransferase)/TSH (thyroid stimulating hormone)/ blood cell analysis indicators found a potential correlation with 6PPD-Q daily excretion and liver/immune functions. Considering this preliminary assessment, systematic research targeting the potential organs at relevant concentrations is required.

Demographic Disparities in Lung Cancer Mortality and Trends in the United States From 1999 Through 2020: A Population-Based CDC Database Analysis.

Lung cancer is the leading cause of cancer-related mortality in the United States and is projected to account for 127,070 deaths in 2023. Although the lung cancer mortality rate has been decreasing over the last decade, demographic disparities in mortality still exist. We sought to determine the impact of demographic factors on lung cancer mortality and trends in the United States. We queried the Centers for Disease Control and Prevention (CDC) database for mortality statistics with an underlying cause of death of lung and bronchus cancer from 1999 through 2020. Age-adjusted mortality rates (AAMR) were calculated per 100,000 people. We assessed the AAMR by demographic variables, including race, geographic density, sex, age, and US census region. Temporal trends were evaluated using Joinpoint regression software, and average annual percent change (APC) was calculated. From 1999 through 2020, lung cancer led to 3,380,830 deaths. The AAMR decreased by 55.1 to 31.8, with an associated average APC of -2.6%. In 1999, men had an AAMR almost twice as high as women, but these differences became less pronounced over time. Rural populations experienced the highest AAMR and the slowest rate of decrease compared with urban populations, who experienced the lowest AAMR and fastest decrease. Non-Hispanic Black individuals experienced the highest AAMR, with an annual decrease of -3.0%. The West experienced the fastest decrease at -3.1% annually, whereas the Midwest experienced the slowest decrease at -2.0% annually. Although the mortality rate of lung cancer has been decreasing since 1999, not all demographic groups have experienced the same rates of decrease, and disparities in outcomes are still prevalent. Vulnerable subgroups need targeted interventions, such as the incorporation of patient navigators, improved screening chest CT scan access and follow-up, and telehealth expansion, which will improve the likelihood of earlier-stage diagnoses and the potential for curative treatments.

Clinical differences between Raoultella spp. and Klebsiella oxytoca.

Raoultella spp. is a genus of bacteria that is known to be closely related to Klebsiella. It has been debated whether Raoultella should be reclassified as a subgroup of Klebsiella. The aim of this study is to compare clinical aspects of Raoultella and Klebsiella oxytoca, a species of Klebsiella that is known to be bacteriologically similar to Raoultella spp. Using data collected at a tertiary care hospital in the United States, we identified 43 patients with Raoultella infection and 1173 patients with Klebsiella oxytoca infection. We compared patient demographics (age and sex), hospitalization status, isolation sites and antibiotic resistance profiles between the two species. There was no significant difference in patient demographics between the two bacteria species. The proportions of intensive care unit (ICU) admission were higher among patients with Raoultella infection (p=0.008). The most common site of isolation was urine for both species (39.5% of all patients with Raoultella spp. vs. 59.3% for K. oxytoca). The second most common site of isolation was blood stream for Raoultella spp. (23.3%) and respiratory tract for K. oxytoca (10.8%). Except for the high proportion of resistant isolates of Raoultella spp. for Trimethoprim/sulfamethoxazole, the antibiotic susceptibility profiles were similar between the two bacteria species. Both were susceptible to ciprofloxacin and meropenem. While there are no significant differences in the patient demographics and antibiotic susceptibility profiles between Raoultella spp. and K. oxytoca, Raoultella may cause more serious infection requiring ICU admissions. Also, Raoultella may cause blood stream infection more frequently than K. oxytoca.

Therapeutic utilization in chronic lymphocytic leukemia: A cross-sectional analysis of the Lymphoma Coalition’s 2022 Global Patient Survey.

e19026 Background: Chronic Lymphocytic Leukemia (CLL) is a highly prevalent disease with heterogenous prognostic trajectories. With a multitude of treatment options, we sought to explore therapeutic utilization trends from a global perspective in order to gain a more in-depth understanding of how different treatment regimens are utilized in different health systems. Methods: In 2022, The Lymphoma Coalition designed and globally deployed a survey to patients with lymphoma and CLL in order to gather patient reported outcomes and patient reported experience measures. Data were collected and enumerated with relevant contingency analyses performed to determine associations with a particular treatment regimen in the context of CLL. Results: The entire cohort of patients with CLL was 1289. The median age of the cohort was 65 and ranged from 26 to 97 years old. Biological sex was equally distributed with 50.5% of respondent indicating that they were female. Respondents were derived from 29 countries. The top three contributors to each region were China (50%), Australia (25%) and New Zealand (18%) for Asia-Pacific (N = 227); France (50%), Italy (13%) and Sweden (7%) for Europe (N = 950); Canada (75%) and The United States (25%) for North America (N = 112). Of those, 636 indicated that they received at least one therapy. The use of chemo-immunotherapy was most common (42%) followed by targeted therapy (32%), immunotherapy alone (18%), and chemotherapy alone (16%). Neither age nor biological sex was a significant predictor of therapy. Europe had the highest rates of chemo-immunotherapy utilization (45%) with North America and Asia-Pacific indicating 32% respectively (p = 0.01). Targeted therapy was used at a higher rate in North America (45%) but failed to demonstrate a significant difference against Asia-Pacific and Europe (31%); (p=0.10). Both immunotherapy and chemotherapy alone failed to demonstrate significant differences across regions. Conclusions: The data support that the majority of patients with CLL who require treatment are most likely to receive combination chemo-immunotherapy utilizing rituximab. However, we acknowledge that the data presented here is two years old and that the use of targeted molecular therapy is likely increasing. We found it reassuring that we could not identify any biases in the administration of the therapeutic regimens across the demographics of age and biological sex. Our research in this space will continue as we have deployed the 2024 version of the Global Patient Survey and have focused on increasing respondent participation from North America. With this new data, we plan on producing a time-dependent model to investigate how emerging therapies enter and expand in the CLL therapeutic space.

Principal component analysis as an efficient method for capturing multivariate brain signatures of complex disorders-ENIGMA study in people with bipolar disorders and obesity.

Multivariate techniques better fit the anatomy of complex neuropsychiatric disorders which are characterized not by alterations in a single region, but rather by variations across distributed brain networks. Here, we used principal component analysis (PCA) to identify patterns of covariance across brain regions and relate them to clinical and demographic variables in a large generalizable dataset of individuals with bipolar disorders and controls. We then compared performance of PCA and clustering on identical sample to identify which methodology was better in capturing links between brain and clinical measures. Using data from the ENIGMA-BD working group, we investigated T1-weighted structural MRI data from 2436 participants with BD and healthy controls, and applied PCA to cortical thickness and surface area measures. We then studied the association of principal components with clinical and demographic variables using mixed regression models. We compared the PCA model with our prior clustering analyses of the same data and also tested it in a replication sample of 327 participants with BD or schizophrenia and healthy controls. The first principal component, which indexed a greater cortical thickness across all 68 cortical regions, was negatively associated with BD, BMI, antipsychotic medications, and age and was positively associated with Li treatment. PCA demonstrated superior goodness of fit to clustering when predicting diagnosis and BMI. Moreover, applying the PCA model to the replication sample yielded significant differences in cortical thickness between healthy controls and individuals with BD or schizophrenia. Cortical thickness in the same widespread regional network as determined by PCA was negatively associated with different clinical and demographic variables, including diagnosis, age, BMI, and treatment with antipsychotic medications or lithium. PCA outperformed clustering and provided an easy-to-use and interpret method to study multivariate associations between brain structure and system-level variables. PRACTITIONER POINTS: In this study of 2770 Individuals, we confirmed that cortical thickness in widespread regional networks as determined by principal component analysis (PCA) was negatively associated with relevant clinical and demographic variables, including diagnosis, age, BMI, and treatment with antipsychotic medications or lithium. Significant associations of many different system-level variables with the same brain network suggest a lack of one-to-one mapping of individual clinical and demographic factors to specific patterns of brain changes. PCA outperformed clustering analysis in the same data set when predicting group or BMI, providing a superior method for studying multivariate associations between brain structure and system-level variables.

Esophageal cancer in the United States: A 21-year mortality analysis (1999-2020).

e23258 Background: Esophageal cancer (EC) is the sixth leading cause of cancer-related deaths in the United States, with a mere 20% survival rate in the first five years, making it a significant public health concern. Considering the lack of comprehensive evaluations of mortality trends that are undergoing substantial transformations on a global scale, this study aims to provide an update on the mortality rates of esophageal cancer and its trends in the United States. Methods: The mortality trends among adults with EC were analyzed using data from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiological Research (CDC WONDER) database, where EC was presented as a contributing or the underlying cause of death. Code C15 “Malignant Neoplasms of Esophagus” in the International Classification of Disease, tenth revision (ICD-10) was used to identify the data. Crude and age-adjusted mortality rates (AAMRs) per 100,000 people were extracted. Annual percent changes (APCs) in AAMRs with 95% CI were obtained using joint point regression analysis across different demographic (sex, race/ethnicity, and age) and geographic (state, urban-rural, and regional) subgroups. Results: Between 1999 and 2020, 309,725 documented deaths were attributed to esophageal cancer. The overall AAMR decreased from 1999-2020 (6.69 to 5.68). Males had higher consistently higher AAMRs than females (10.96 vs. 2.24). NH White had the highest overall AAMR (6.88), followed by NH Black (6.46), NH American Indian (4.95), Hispanic or Latino (3.31), and NH Asian or Pacific Islander (2.57). CMRs also increased with advancing age and were greatest in individuals over the age of 85 years. AAMR also varied by region (overall AAMR: Midwest: 7.18; Northeast: 6.75; South: 6.07; West: 5.76), and non-metropolitan areas had higher AAMR (non-core areas: 7.09; micropolitan areas: 7.19) than metropolitan areas (large central metropolitan areas: 5.75; large fringe areas: 6.33). The states in the upper 90th percentile of esophageal cancer-related AAMR were Vermont, District of Columbia, West Virginia, Ohio, New Hampshire, and Maine, and exhibited an approximately two-fold increase in AAMRs, compared to states falling in the lower 10th percentile. Conclusions: Over the last two decades, there has been an overall decline in mortality related to EC in the United States. However, demographic and geographic discrepancies in EC-related mortality persist, necessitating additional exploration and development of specifically directed treatments.

Unintentional weight loss, body composition, and all-cause mortality among United States adults with cancer.

e22527 Background: While unintentional weight loss (UWL) is a common presenting symptom of malignancy, weight changes also occur regularly in patients with diagnosed cancer.UWL is often characterized by considerable muscle and fat loss and can lead to cachexia, which may increase risk of mortality. This nationally representative study aims to assess the association between UWL and mortality among adults with history of cancer and characterize differences in body composition. Methods: This was a retrospective cohort study of the National Health and Nutrition Examination Survey 1999-2018 linked to the 2019 National Death Index. We identified adults with self-reported history of cancer, excluding non-melanoma skin cancer. Weight change was determined as the difference between current weight and self-reported weight 1 year prior to interview. We categorized weight change into: UWL (unintentionally losing &gt; 5% of weight), intention weight loss (IWL) (intentional loss &gt; 5% weight), no weight change (NWC) (≤5% weight change), weight gain (WG) ( &gt; 5% weight gain). We estimated risk of all-cause mortality using gender-stratified multivariable Cox regression, adjusting for demographics (age, race, income, education, insurance status), sociobehavioral factors (smoking, alcohol, nutrition, physical activity, self-reported health), comorbidities, and albumin. We additionally identified participants with cancer who had whole-body dual x-ray absorptiometry scans (2011-2018) and assessed body composition measurements including total lean mass, lean-to-fat ratio, subcutaneous fat mass, and visceral fat mass by weight change category using multivariable linear regression. Results: Among 3,153 participants (mean age 62 years, 55% women, 82% non-Hispanic White), the top four primary cancers were breast (21%), prostate (14%), melanoma (11%), and cervical (11%). Approximately 9% of men and 11% of women experienced UWL. Adults with UWL were more likely to have lower socioeconomic status, more functional limitations, and higher comorbidity burden. Across a median 7 years (IQR, 3-11y) follow-up, 22% of females and 34% of men died. Both men and women experiencing UWL had more than 2 times the risk of all-cause mortality compared to NWC (adjusted HR [95% CI]; men: 2.02 [1.47, 2.78]), women: 2.43 [1.78, 3.34]). Participants with UWL had less subcutaneous fat mass (-113g, 95% CI [-242, 16]) and visceral fat mass (-65g, 95% CI [-146, 16]) compared to NWC, though not statistically significance. Conclusions: UWL in patients with history of cancer is independently associated with more than 2 times the risk of all-cause mortality in both men and women. UWL was associated with proportional loss of both subcutaneous and visceral fat mass. Further longitudinal studies examining UWL’s impact on body composition changes and downstream outcomes by cancer type and stage are needed.

Eco-chic or trendy-chic? Decoding consumer preferences in sustainable and fast fashion across the EU

Abstract The ongoing transformation of the fashion industry is driven by an increasing focus on sustainability, ethical practices, and responsible consumer behavior. Simultaneously, social media platforms have emerged as influential forces in this field, shaping fashion trends and consumer preferences. Despite a substantial body of literature investigating consumer preferences between fast and sustainable fashion, a gap in understanding the intricate relationship between fashion preferences, socio-economic profiling, and social media engagement is evident. Thus, this research was aimed at comparatively decoding EU consumers’ preferences for fast fashion against sustainable fashion by exploring the interplay of demographic factors ‒ age, gender, and geographical location ‒ on fashion preferences, as expressed through the digital engagement with fashion-related content on the Meta social platforms. The research methodology implied resorting to logistic regression analysis, aiming to uncover the underlying patterns that fundamentally characterize consumers’ preferences for fashion in the EU. The results provide novel insights into how digital engagement with fashion-related content can act as a barometer for regional fashion identities and preferences, useful for the identification of both convergence and inflection points. Moreover, findings offer a robust foundation for crafting strategies that promote sustainable fashion practices, tailored to specific EU age, gender, and location demographics, by leveraging the insights gained about EU consumer preferences.

Relationship Between Lipid Profile and Body Mass Index in Patients With Polycystic Ovarian Syndrome: A Cross-Sectional Study Among Indian Women of Reproductive Age.

Introduction Characterized by a range of symptoms including irregular menstrual cycles, hirsutism, and infertility, polycystic ovarian syndrome (PCOS) also poses substantial metabolic challenges. Among these, dyslipidemia and obesity are particularly concerning due to their long-term implications for cardiovascular health.The present study explores the intricate relationship between lipid profile and body mass index (BMI) in patients with PCOS presenting to the Department of Obstetrics and Gynaecology,King George's Medical University, Lucknow, a tertiary care teaching hospital in Northern India. Methods The present work involves analysis of clinical characteristics of 230 premenopausal women between 18-45 years of age diagnosed with PCOS (according to Rotterdam Criteria). Patientswith conditions such as congenital adrenal hyperplasia; Cushing's syndrome; uncontrolled hypertension, smoking,hypogonadism; using oral contraceptives; pregnant or lactating mothers; smoking or drug addiction; psychiatric illness; and those diagnosed with androgen-secreting tumors were excluded. For each participant, data was collected pertaining to demographics (age, marital status), clinical presentation,height, and weight (for BMI calculation), and total lipid profile comprising of total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and very low-density lipoprotein cholesterol (VLDL-C). Thepatients were stratified according to their BMI as per the WHO Asian classification, andPearson's correlation coefficient was calculated to see the correlation between lipid profile and BMI. Results The final analysis was done on 228 patients, with a mean age of25.22 (±4.82) years, and 45.6% were currently married. Among the participants, 28.1% of the participants were overweight, and 42.5% of them classified as obese, while the remaining 29.4% had a BMI in the normal range.The mean (SD) total cholesterol was 172.26 (49.55) mg/dl, and 65 patients (28.5%) had elevated serum cholesterol (≥200 mg/dl). Triglycerides were raised (≥ 150 mg/dl) in a majority of the study participants (n=160, 70.2%). While none of the patients had high VLDL-C, LDL-C was elevated in 52 patients (22.8%). HDL-C levels were lower than the threshold value of 50 mg/dl in 152 participants (66.7%). On performing correlation analysis, a significant negative correlation was noted between HDL-C and BMI in the entire study cohort (r=-0.342, p=0.003). Overweight patientsexhibited a statistically significant positive correlation between triglycerides and BMI (r=2.628, p=0.002). Participants with BMI in the overweight range demonstrated statistically significant correlations with HDL-C (r=-0.497, p=0.017) and triglycerides (r=2.628, p=0.002); and BMI of obese patients significantly correlated with total cholesterol (r=0.301, p=0.037) and triglycerides (r=0.146, p=0.028). Conclusion The findings of the study underscore the multifaceted nature of PCOS, affecting reproductive health as well as metabolic components. The significant correlations between BMI and lipid parameters, specifically, HDL-C, triglycerides, and total cholesterol, highlight the importance of weight management in reducing cardiovascular risks in women with PCOS.

EHR documentation of cost discussions and financial interventions for a cohort of patients with advanced cancer: Findings from a retrospective chart review-based study.

e23150 Background: Financial Toxicity (FT), the adverse impact of high medical costs on quality of life, notably affects many oncology patients. In a prior initiative to improve quality of life for advanced cancer patients, a palliative care-trained nurse practitioner (PCNP) was embedded in an academic oncology practice. Patients completed the Edmonton Symptom Assessment System (ESAS) and Canadian Problem Checklist (CPC) to gauge physical symptoms, psychosocial issues, and financial concerns. However, the incidence of self-reported financial issues and electronic health record (EHR) documentation of cost discussions and interventions remain unclear for this patient group. Methods: The study included adult oncology patients with advanced cancer seen by the PCNP from January 1, 2020, to January 1, 2022. We assessed incidence of self-reported financial concerns via CPC checklists in this cohort. Ten charts underwent detailed manual review for evidence of cost discussions or referral to finance-related interventions for up to 1 year from the initial consult with the PCNP or until death. During the review, we identified keywords in documentation of cost discussions and finance-related interventions to create a keyword library. We iteratively compared the library to our reference standard manual chart review to ensure 100% sensitivity. We then employed this keyword library to evaluate the remaining charts. Descriptive statistics were employed to assess correlations between self-reported financial concerns, chart documentation of cost discussions or financial interventions, and patient demographics. Results: Out of 109 eligible patients, 71% (77) completed pre-visit questionnaires, with 30% (23) reporting financial issues. Of this group, 43% (10) died during the study period. Average follow-up was 5.0 months among the decedents. Among those reporting financial concerns, 65% (15) had documented cost discussions or financial assistance referrals in the EHR, involving physicians, social workers, and other clinic staff. Most interventions addressed medication costs and referrals to financial assistance as indicated. Patient demographics (age, sex, insurance type) showed no apparent association with chart documentation of cost discussions or financial assistance. Conclusions: We used retrospective chart review to evaluate the extent of documentation of cost discussions and finance-related intervention in a cohort of patients with advanced cancer. In our patient cohort, 30% self-reported financial concerns, a proportion consistent with previously reported incidence of FT among oncology patients. Notably, 35% of the patients with known financial concerns had no other relevant documentation in the EHR. More work is needed to establish best practices for systematic screening for FT and interventions to support patients.

Breaking through barriers: Unraveling challenges in clinical trial participation among oncologic patients in a developing country.

11144 Background: Clinical trials are vital for advancing cancer research and treatment development, yet obstacles to participation impede progress, particularly in regions with limited clinical research awareness, such as Brazil. Methods: This study was conducted in a single cancer center in São Paulo, Brazil, between 2020 and 2022. A tailored questionnaire comprising demographic (age, gender, income) and barrier-related sections explored patient-related (10 questions), protocol-related (7 questions), and physician-related (5 questions) barriers. Results: Among 206 oncologic patients enrolled in the study, 43.7% were from the public healthcare system, and 56.3% had private insurance. Patients who self-declared as white were 59.7%, and those who self-declared as brown/black were 35.9%. Patient-related challenges included unfamiliarity with trial participants (84.6%), concerns about daily life disruptions (75.4%), and transportation difficulties (66.2%). Protocol-related obstacles involved fears of unknown side effects (62.3%), inability to choose treatment (47.6%), and potential assignment to a placebo group (46.8%). Physician-related barriers included communication issues, strained doctor-patient relationships (94.7%), and patient deference to doctors' decisions (55.4%). Higher-income patients and those in the public health system demonstrated greater clinical research awareness. Conclusions: The study emphasizes the critical role of patient education in overcoming barriers to clinical trial participation in oncologic patients. Furthermore, it underscores the necessity of addressing disparities among minority populations, such as non-white individuals with lower incomes, to transform clinical research and ensure universal access to newer therapies. Efforts should be directed towards inclusivity, bridging awareness gaps, and fostering a comprehensive understanding of the benefits of clinical trial participation for all cancer patients.

Impact of aromatase inhibitors on mortality and hospitalization costs in patients with breast cancer: A National Inpatient Sample analysis 2020.

e13160 Background: Breast cancer is a significant public health concern globally, affecting millions of individuals each year. Aromatase inhibitors are a class of medications commonly used in the treatment of hormone receptor-positive breast cancer. The significance of the study lies in the impact of aromatase inhibitors on mortality and also healthcare-related costs for the treatment of breast cancer. Methods: The National Inpatient Sample database (2020) was used to identify adult patients with breast cancer using ICD-10 codes. Demographics (age, race, sex, region, and hospital size), co-morbidities, and hospitalization costs were compared between the two groups of patients: those who are on aromatase inhibitors and those who are not. The odds of mortality were analyzed. A p&lt;0.05 was considered statistically significant. Results: Out of 166870 patients who had breast cancer, 12975(7.7%) were on aromatase inhibitors. The aromatase inhibitors group was relatively older (median age, 69.4 years vs 64 years) and predominantly white (71.50% vs 66%) compared to the non-aromatase inhibitors group. The prevalence of heart failure and osteoporosis was greater in the aromatase inhibitors group than in the non-aromatase inhibitors group. The adjusted odds ratio of mortality in the aromatase inhibitors group was 0.45, 95% CI (0.39-0.50, p&lt;0.0001). Furthermore, the average total cost of hospitalization in the aromatase inhibitor group was $6426 less than the non-aromatase inhibitor group. Conclusions: Our study findings indicate that breast cancer patients treated with aromatase inhibitors experienced lower odds of mortality and lesser costs of hospitalization. However, the aromatase inhibitor group was found to have a higher prevalence of heart failure and osteoporosis. Hence, further research needs to be done on potential adverse effects and long-term effects of the aromatase inhibitors treatment.

Central pathological review and molecular classification of medulloblastoma in countries with limited resources: A commitment to equitable access.

10062 Background: Medulloblastoma, the most common malignant pediatric brain tumor, exhibits molecular heterogeneity influencing prognosis and treatment decisions. This study focuses on feasibility the pathological review and molecular classification with cost-effective methods. Methods: From December 2018 to November 2023, we analysed samples of patients referred to our laboratory. Data were collected on patient demographics (age, gender, origin), pathological review and specific medulloblastoma subtypes identified. The study was performed without costs for parents or institutions. Results: During the study period, 146 patients were included. The predominant age groups being 0 to 4 years (20.1%) and 5 to 9 years (36.1%) The mean age was 10.2 years. 55.6% of patients were female and 43.8% were male. Ninety-three patients were from Brazil and 7% from Latin America. Of the 117 samples that could be analyzed, 43% was classified as group 4, 37% were sonic hedgehog (SHH) group, 10% were group 3 and 4% were WNT group. Five percent of the samples had inconclusive results, with two patients had diagnoses other than medulloblastoma. Seventy percent of samples had a turnaround time for molecular classification results around 30 days. Conclusions: This study highlights the importance of central review pathology and molecular classification in medulloblastoma management. Our results emphasize the feasibility of centralized pathology review and molecular classification in countries with limited resources and provide equity for all patients. Based on this experience, we have expanded for other brain and pediatric tumors. Our effort contributes to ensuring that every patient benefits from the advancements in personalized medicine and this represents a real step to offer the same chances of cure for everyone.

Impact of Economic Factors on the Process of Population Transition from Labour Activity to Pension in the Republic of Moldova

Abstract The purpose of research is to analyse the impact of population ageing process on labour force market, as well as economic factors on the transition from labour activity to pension in the Republic of Moldova. The change in the structure of labour force to wards elder ages, as well as interruption of active economic activity and retirement is one of the factors in economic growth slowdown, which is conditioned by a reduction of labour force reproduction and its growth. In this situation, in order to mitigate the negative consequences of labour force deficit, it is necessary to take effective measures to increase labour productivity not only to ensure economic growth, but also to ensure the welfare of the country’s population and meet the necessities of an increased share of the population-dependents (both the elderly population and children under 15). Taking into account the relevance of the above-mentioned problem, the analysis of the relationship between economic factors and the transition from labour activity to pension in the conditions of demographic ageing was carried out, including the evaluation of the role of economic factors in making a decision to exit from the labour market to pension. In this context, the comparative quantitative and qualitative analysis of tendencies in the economically active and employed population was carried out, including pre- and pension ages and the phenomenon of precarious employment, the demographic coefficient of dependence on old age, the dependence of pension from the income level, and the financial stability of the Social Insurance Budget. The proposals to improve the effectiveness of government policies in regulation and harmonization the transition from the labour market to pension, including the continuation of active economic activity was elaborated in order to reduce the negative consequences connected with the process of population ageing and to ensure the stability of labour market development. The article is developed in the framework of the research Subprogramme “The demographic transition in the Republic of Moldova: particularities, socioeconomic implications and demographic resilience straightening” (2024-2027).

Trends and Missing Links in (De)Hydration Research: A Narrative Review.

Despite decades of literature on (de)hydration in healthy individuals, many unanswered questions remain. To outline research and policy priorities, it is fundamental to recognize the literature trends on (de)hydration and identify current research gaps, which herein we aimed to pinpoint. From a representative sample of 180 (de)hydration studies with 4350 individuals, we found that research is mainly limited to small-scale laboratory-based sample sizes, with high variability in demographics (sex, age, and level of competition); to non-ecological (highly simulated and controlled) conditions; and with a focus on recreationally active male adults (e.g., Tier 1, non-athletes). The laboratory-simulated environments are limiting factors underpinning the need to better translate scientific research into field studies. Although, consistently, dehydration is defined as the loss of 2% of body weight, the hydration status is estimated using a very heterogeneous range of parameters. Water is the most researched hydration fluid, followed by alcoholic beverages with added carbohydrates (CHO). The current research still overlooks beverages supplemented with proteins, amino acids (AA), and glycerol. Future research should invest more effort in "real-world" studies with larger and more heterogeneous cohorts, exploring the entire available spectrum of fluids while addressing hydration outcomes more harmoniously.
