Predictive role of monocyte count for significant coronary artery disease identification in patients with stable coronary artery disease.

The coronary artery disease (CAD) remains the leading cause of morbidity that is characterized by broad spectrum of symptoms. Up to 30% of performed angiographies reveal normal coronary arteries. The aim of the study was to find simple predictor for significant epicardial artery stenosis among patients with chronic coronary syndrome. There were 187 patients (131 (709%) men and 56 (30%) women) in the median (Q1-Q3) age of 67 [58-72] presenting with stable CAD symptoms enrolled into the present retrospective analysis. The demographical, clinical and laboratory characteristics between patients with normal and significant coronary artery stenosis were compared. The multivariable analysis revealed coexistence of hypercholesterolemia as significant differentiation factor (odds ratio [OR]: 4.38, 95% confidence interval [CI]: 1.78-10.80, p = 0.001) for significant CAD and inverse relation to serum high density lipoprotein (OR: 0.19, 95% CI: 0.05-0.72, p = 0.015) and relation to creatinine concentration (OR: 1.03, 95% CI: 1.00-1.05, p = 0.012). Among whole peripheral blood count analysis, the significant relation was noticed to be hemoglobin concentration (OR: 1.09, 95% CI: 1.10-1.18, p = 0.022) and monocyte count (OR: 32.3, 95% CI: 1.09-653.6, p = 0.017). Receiver operator curve revealed (AUC: 0.641, p = 0.001) with the optimal cut-off value above 0.45 K/uL for monocyte, yelding sensitivity of 81.82% and specificity of 58.06%. The peripheral monocyte count above 0.45 k/uL may be considered as a predictor of significant coronary artery disease in symptomatic patients with chronic coronary syndrome.

Association of Plasma Zinc Status with Severity of Lesions in Patients with Acne Vulgaris: A Cross-Sectional Study

Background: Zinc (Zn) is an essential trace mineral that plays a critical role in maintaining overall skin health and functionality. Zn deficiency has been linked to various dermatological conditions, including acne, eczema, and delayed wound healing, highlighting the mineral’s indispensable role in promoting skin resilience and health. Some investigators have refuted these findings. Objective: was to determine plasma Zn level and Zn status in patients with Acne vulgaris (AV) belonging to Nowshera, Khyber Pakhtunkhwa (KPK) and to find any possible relationship between Zn status & severity of the acne lesions. Methods: Hundred patients of either sex with untreated AV were randomly selected in a cross-sectional study. Based on the Global Acne Grading System (GAGS) the acne lesions were categorized as mild, moderate & severe. Blood samples were taken for determination of serum Zn. The relationship of Zn status with severity of lesions was determined with Pearson Correlations coefficient (r). Results: The study included 42 males and 58 females with male to female ratio of 1:1.4. Mean age was 21.8 years. The average plasma zinc level across the cohort was 67.4 ± 12.6 µg/dL, with males showing slightly higher zinc levels (69.1 ± 11.8 µg/dL) than females (65.8 ± 13.2 µg/dL), though this difference was not statistically significant (p = 0.092). 22% had mild acne, 46% moderate acne and 32% had severe acne. Patients with severe acne had significantly lower plasma zinc levels (60.2 ± 10.4 µg/dL) compared to those with mild acne (73.1 ± 13.1 µg/dL) (p < 0.01). Pearson’s correlation analysis revealed a significant inverse relationship between plasma zinc status and acne severity (r = -0.43, p < 0.001), indicating that lower zinc levels were associated with more severe acne. No significant gender differences were observed in the relationship between zinc levels and acne severity. Conclusion: Pasma Zn concentration is markedly decreased in patients with AV and the more severe is the lesion, the more Hypozincemia. Hence, Plasma Zn status is associated negatively with severity of AV lesions in the studied population.

Opportunistic Computed Tomography: A Novel Opportunity for Osteoporosis Screening.

Retrospective review. To use opportunistic computed tomography (CT) screening to determine the prevalence of osteoporosis (OP) in patients presenting with spinal fractures and the rate of identification and treatment at our institution. OP remains a highly underdiagnosed and undertreated disease. Opportunistic abdominopelvic CT scans offer a feasible, accessible, and cost-effective screening tool for OP. Retrospective review of 519 patients presenting as trauma activation to the emergency department of a Level 1 Trauma Center after a spinal fracture. Patients were excluded if under the age of 18 or lacking a CT scan upon arrival in the emergency department. Hounsfield Units (HU) were measured at the L1 vertebral level on CT scans to determine bone density levels. Values of ≤100 HU were considered osteoporotic, whereas 101-150 HU were osteopenic. A total of 424 patients were included. The average HU was 204.8 ± 74.3 HU. Of the patients, 16.7% were diagnosed as osteopenic and 9.9% as osteoporotic. The mean age was 65 ± 14 years for osteopenic patients and 77 ± 11 years for osteoporotic. A statistically significant inverse relationship was found between age and bone density. Of the patients, 42.5% with low bone density HU measurements had a previously documented history of OP/osteopenia. There was a statistically significant association between females and low bone density. Patients injured in a fall were statistically significantly more likely to have lower bone densities than those in motor vehicle accidents. Of the osteoporotic patients, 9.5% were treated by our institution's fragility fracture team. Our study shows that among a cohort of patients with spinal fractures, 58% of patients with radiographic signs of OP are currently undiagnosed, resulting in a low treatment rate of OP. Increasing and standardizing the use of opportunistic CT scans would allow an increase in the diagnosis and treatment of OP in patients with spinal fractures. Further, opportunistic CT scans could also be useful for a broader orthopedic population at high risk of fragility fractures. Level II-therapeutic.

Navigating Crisis: Resilience and Mental Well-being in Post-COVID Cyprus Students

Abstract Background The mental health of university students is identified as a major challenge in public health, exacerbated by the COVID-19 pandemic. The pandemic and its aftermath have brought forth several stresses, which have had a substantial influence on university students’ mental health. Understanding how resilience, which is crucial in coping with adversity, influences students’ responses to these difficult circumstances is critical. Objectives This study aims to examine the relationship between resilience and mental health outcomes among university students in the Republic of Cyprus after the COVID-19 pandemic. Methods Using a parallel embedded mixed methods approach, resilience was measured using the Conner-Davidson Resilience Scale (CD-RISC) while mental health outcomes were assessed using the Symptom Checklist 90-Revised (SCL 90-R) among a preliminary sample of 470 students. The association between the two was assessed by linear regression analysis, adjusting for potential confounders, and also stratifying by gender. Results Preliminary findings from this ongoing study revealed a significant inverse relationship between resilience and mental health (beta= -0.58, 95% CI -0.88, -0.29), regardless of gender, age, or socioeconomic status. Stratifying by gender revealed for males, the association between resilience and mental health is (beta= -0.50, 95% CI -0.98, -0.32), whereas for females, it is (beta= -0.63, 95% CI -1.04, -0.22). In short, the influence of resilience on protecting mental health appears to be slightly more prominent in women than in males. Discussion This study enriches our understanding of the intricate interplay between the COVID-19 pandemic, resilience, and mental health outcomes among university students. By prioritizing the psychological well-being of this population group, our findings resonate with the World Health Organization’s advocacy for heightened mental health awareness during crises. Key messages • Prevalence of mental health issues post pandemic era among university students. • Resilience as a buffer for mental health crisis in young adults.

What is the optimal range of fasting stress hyperglycemia ratio for all-cause mortality in American adults: An observational study.

To date, no studies have been conducted to assess the impact of fasting stress hyperglycemia ratio (SHR) on all-cause mortality. Therefore, the objective of our study is to investigate the association between SHR and all-cause mortality in a population of American adults. The study population was derived from NHANES data spanning from 2005 to 2018. The exposure variable SHR was derived from fasting blood glucose (FBG) and glycosylated hemoglobin (HbA1c%), and the specific calculation formula was as follows: (FBG (mmol/L))/(1.59 × HbA1c (%) - 2.59). The outcome variable was all-cause mortality. A total of 18,457 participants were enrolled in this prospective cohort study. Following a median follow-up period of 90 months, all-cause mortality was observed in 10.32% of the subjects. Cox proportional hazards regression model indicates that there is no significant difference between SHR and all-cause mortality in the fully adjusted model, whether analyzed as a continuous or categorical variable (P for trend > 0.05). Through the 2-piecewise Cox proportional hazards regression model, we have determined that the inflection point of SHR in relation to all-cause mortality is 0.88. It has also been observed that when the value of SHR is on the left side of the inflection point (SHR ≤ 0.88), there is a significant 77% (HR: 0.23; 95% CI: 0.10-0.50) reduction in all-cause mortality for each additional unit increase in SHR. Conversely, when the value of SHR exceeds 0.88, there is a substantial 2.40-fold (HR: 2.40; 95% CI: 1.61-3.58) increase in the risk of all-cause mortality (P for log likelihood ratio test < .001). The subgroup analysis results demonstrate that sex has the potential to modify the association between SHR and all-cause mortality within the population exhibiting SHR ≤ 0.88. The relationship between SHR and all-cause mortality follows a U-shaped pattern, where in the lowest risk of death for the average American adult is observed at an SHR value of 0.88. Furthermore, in men with SHR ≤ 0.88, there is a significant inverse relationship between the increase in SHR and the risk of all-cause mortality.

Dietary calcium intake among Iranian adults: Iranian Multicenter Osteoporosis Study (IMOS-2021).

Adequate dietary consumption of calcium is crucial in the preservation of bone health and the prevention of osteoporosis. This study investigated the prevalence of insufficient dietary calcium intake among individuals aged ≥50 years in Iran. We analyzed data from the Iranian Multicenter Osteoporosis Study (IMOS-2021). Participants aged 50 years and older completed a 168-item food frequency questionnaire. Insufficient dietary calcium intake was characterized as a daily calcium intake of <1000 mg for men aged 50-70 years, and <1200 mg for men over 70 years and women over 50 years and older. Stata v17 statistical software facilitated a survey set analysis to estimate the population's mean and median dietary calcium intake and the prevalence of insufficient dietary calcium intake. The study included 1450 participants with a mean age of 60.7±7.9 years. The estimated mean dietary calcium intake in Iran was 1062.7 mg/day (95% CI: 1029.6-1095.8), with a median intake of 943.5 mg/d (95% CI: 910.5-976.4). The prevalence of insufficient dietary calcium intake in Iran was estimated to be 62.9% (95% CI: 60.0%-65.7%). Notably, the prevalence was higher among women at 75.5% (95% CI: 71.9%-78.8%), compared to men at 47.8% (95% CI: 43.4%-52.3%) with a significant difference (P<0.001). In age-related findings, individuals aged 65 years and older had a higher prevalence of insufficient intake, at 69.0% (95% CI: 63.9%-74.0%), versus those under 65 years, at 60.3% (95% CI: 56.9%-63.8%), with this difference being statistically significant (P = 0.007). Furthermore, a significant inverse relationship was identified between both educational years and socioeconomic status and the prevalence of insufficient dietary calcium intake (Ps for trends<0.001). Our findings revealed a significant prevalence of insufficient dietary calcium intake in women and those aged 65 and older. We advocate for targeted public health strategies to ensure sufficient dietary calcium intake across these populations.

Assessment of Environmental Pollutants and their Relationship with Chronic Respiratory Disease Exacerbations in Jamshoro: A Cross-Sectional Study

Background: COPD and Asthma are a burden to our society and in a city like Jamshoro having industries and power plants in close vicinity, this becomes a greater concern. The objective of this cross-sectional study was to evaluate the relationship between air quality indices (AQIs) and exacerbations in chronic obstructive respiratory diseases such as asthma and COPD, prevalent among the general population in Jamshoro. Methods: This cross-sectional study, conducted from August 2023 to February 2024 at LUMHS, Jamshoro (ERC approval: 14287/23/081), used purposive sampling to recruit 300 adults with asthma or COPD. Air quality data (PM10, PM2.5, NO2, SO2) were collected, and respiratory outcomes were measured via spirometry and a validated questionnaire. Pearson’s correlation and multiple regression analyzed the association between air quality and exacerbations. Ethical approval and informed consent were obtained. Results: There was a significant inverse relationship between PM10, NO2, and FEV1 (r = -0.45, p &lt; 0.01; r = -0.40, p &lt; 0.01). Chi-square analysis indicated a strong association between AQI categories and exacerbation rates (χ² = 25.6, df = 3, p &lt; 0.001). Multiple regression showed that PM10 and NO2 were significant independent predictors of respiratory exacerbation (β = 0.049, p &lt; 0.01; β = 0.038, p &lt; 0.01). Conclusion: The study underscores the adverse respiratory health consequences of poor air quality in Jamshoro and recommends the implementation of effective air quality management policies.

Assessment of the Effects of Biochar on the Physicochemical Properties of Saline–Alkali Soil Based on Meta-Analysis

Enhancing global agricultural sustainability critically requires improving the physicochemical properties of saline–alkali soil. Biochar has gained increasing attention as a strategy due to its unique properties. However, its effect on the physicochemical properties of saline–alkali soil varies significantly. This study uses psychometric meta-analysis across 137 studies to synthesize the findings from 1447 relatively independent data sets. This study investigates the effects of biochar with different characteristics on the top 20 cm of various saline–alkali soils. In addition, aggregated boosted tree (ABT) analysis was used to identify the key factors of biochar influencing the physicochemical properties of saline soils. The results showed that biochar application has a positive effect on improving soil properties by reducing the sodium adsorption ratio (SAR) and the exchangeable sodium percentage (ESP) by 30.31% and 28.88%, respectively, with a notable 48.97% enhancement in cation exchange capacity (CEC). A significant inverse relationship was found between soil salinity (SC) and ESP, while other factors were synergistic. Biochar application to mildly saline soil (&lt;0.2%) and moderately saline soil (0.2–0.4%) demonstrated greater improvement in soil bulk density (SBD), total porosity (TP), and soil moisture content (SMC) compared to highly saline soil (&gt;0.4%). However, the reduction in SC in highly saline soil was 4.9 times greater than in moderately saline soils. The enhancement of soil physical properties positively correlated with higher biochar application rates, largely driven by soil movements associated with the migration of soil moisture. Biochar produced at 401–500 °C was generally the most effective in improving the physicochemical properties of various saline–alkali soils. In water surplus regions, for mildly saline soil with pH &lt; 8.5, mixed biochar (pH 6–8) at 41–80 t ha−1 was the most effective in soil improvement. Moreover, in water deficit areas with soil at pH ≥ 8.5, biochar with pH ≤ 6 applied at rates of &gt;80 t ha−1 showed the greatest benefits. Agricultural residue biochar showed superior efficiency in ameliorating highly alkaline (pH ≥ 8.5) soil. In contrast, the use of mixed types of biochar was the most effective in the amelioration of other soil types.

Assessment of Paraoxonase 1 and Arylesterase Activities and Lipid Profile in Bodybuilders: A Comparative Study of Physical Activity and Anthropometry on Atherosclerosis.

Background and Objectives: Atherosclerosis, driven by dyslipidaemia and oxidative stress, is a leading cause of cardiovascular morbidity and mortality. This study evaluates the effects of vigorous-intensity bodybuilding exercise (VIBBE) on atherosclerosis biomarkers-including paraoxonase-1 (PON1) and arylesterase (ARE) activities-and lipid profiles in male bodybuilders who do not use anabolic-androgenic steroids. Comparisons were made with individuals engaged in moderate-intensity aerobic exercise (MIAE), as well as overweight/obese sedentary (OOS) and normal-weight sedentary (NWS) individuals. Materials and Methods: A cross-sectional study was conducted involving 122 healthy male participants aged 18-45 years, divided into four groups: VIBBE (n = 31), OOS (n = 30), MIAE (n = 32), and NWS (n = 29). Anthropometric assessments were performed, and fasting blood samples were collected for biochemical analyses, including lipid profiles and PON1 and ARE activities. Statistical analyses compared the groups and evaluated correlations between adiposity measures and atherosclerosis biomarkers. Results: The VIBBE group exhibited significantly lower levels of low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and logarithm of the TG to high-density lipoprotein cholesterol (HDL-C) ratio [log(TG/HDL-C)] compared to the OOS group (p < 0.05 for all), indicating improved lipid profiles. However, these improvements were not significant when compared to the NWS group (p > 0.05), suggesting that VIBBE may not provide additional lipid profile benefits beyond those associated with normal weight status. PON1 and ARE activities were significantly lower in the VIBBE group compared to the MIAE group (p < 0.05 for both), suggesting that VIBBE may not effectively enhance antioxidant defences. Correlation analyses revealed significant inverse relationships between PON1 and ARE activities and adiposity measures, including body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), body fat percentage (BFP), fat mass index (FMI), and obesity degree (OD) (p < 0.05 for all). Positive correlations were observed between oxLDL and log(TG/HDL-C) and adiposity measures (p < 0.05 for all). Conclusions: Vigorous-intensity bodybuilding exercise improves certain lipid parameters compared to sedentary obese individuals but does not significantly enhance antioxidant enzyme activities or further improve lipid profiles beyond those observed in normal-weight sedentary men. Conversely, moderate-intensity aerobic exercise significantly enhances PON1 and ARE activities and improves lipid profiles, offering superior cardiovascular benefits. These findings underscore the importance of incorporating moderate-intensity aerobic exercise into physical activity guidelines to optimize cardiovascular health by balancing improvements in lipid metabolism with enhanced antioxidant defences.

Association between dietary fiber intake and chronic kidney disease in adults with and without hypertension in the United States: a cross-sectional study of NHANES 2009–2020

While previous research has highlighted the potential advantages of increasing dietary fiber intake (DFI) for managing hypertension and chronic kidney disease (CKD), there is a gap in large-scale empirical studies examining the relationship between DFI and CKD among hypertensive and nonhypertensive cohorts independently. This study involved 22,871 participants sourced from the NHANES database spanning 2009 to 2020, who were divided into hypertensive (n = 9,861) and nonhypertensive (n = 13,010) groups. The analysis revealed a significant inverse correlation between DFI and CKD prevalence across the sample after adjusting for various covariates (OR = 0.98, 95% CI: 0.97–0.99, p = 0.001). Within the subset of hypertensive individuals, this inverse association mirrors the findings of the overall sample, indicating that a higher DFI was associated with a reduced occurrence of CKD (OR = 0.97, 95% CI: 0.96–0.99, p < 0.001). However, this correlation was not detected in the nonhypertensive group (OR = 0.99, 95% CI: 0.98–1.01, p = 0.285). The RCS analysis further confirmed a pronounced nonlinear inverse relationship between DFI and CKD prevalence in both the entire cohort and the hypertensive group but not in the nonhypertensive group. Further scrutiny of the hypertensive group revealed that individuals with a higher DFI had 33% lower odds of CKD progression for the moderate risk level and 36% lower odds for the high to very high risk level. Subgroup analyses confirmed the consistency of these relationships across various demographics. In summary, this investigation revealed a significant inverse relationship between DFI and CKD prevalence in US adults with hypertension, a relationship not observed in nonhypertensive individuals.

Environmental stress and salivary cortisol levels in preterm infants.

Preterm infants are exposed to numerous environmental stressors during their Neonatal Intensive Care Unit (NICU) stay, particularly during the first week after birth. The aim of this study is to assess whether salivary cortisol levels are correlated with Neonatal Infant Stressor Scale (NISS) scores in preterm infants during the first week of life. We also quantified the changes in both NISS scores and cortisol levels in the first week, and whether cortisol levels are associated with gestational age. Preterm infants (n = 38, birth weight <1250 g and/or gestational age <29 weeks) were included. Saliva samples were collected on day 0-3 (early) and day 4-7 (late), and cortisol concentrations were measured by immunoassay. NISS scores were assessed retrospectively for the six hours preceding each saliva collection. NISS scores were not significantly correlated with salivary cortisol levels at either time point. However, infants born at <28 weeks gestation had higher median cortisol levels than infants born at >28 weeks (p = 0.0068), and there was also a significant inverse relationship between NISS score and gestational age (p = 0.04). There was no significant difference between the early and late time points for either NISS scores or cortisol levels. Cortisol levels are elevated in infants <28 weeks gestation but do not correlate with NISS scores. NISS scores are inversely related to gestational age, likely reflecting increased exposure to interventions and invasive procedures for the smallest infants.

DTI fiber-tracking parameters adjacent to gliomas: the role of tract irregularity value in operative planning, resection, and outcome.

The goal of glioma surgery is maximal tumor resection associated with minimal post-operative morbidity. Diffusion tensor imaging-tractography/fiber tracking (DTI-FT) is a valuable white-matter (WM) visualization tool for diagnosis and surgical planning. Still, it assumes a descriptive role since the main DTI metrics and parameters showed several limitations in clinical use. New applications and quantitative measurements were recently applied to describe WM architecture that surround the tumor area. The brain adjacent tumor area (BAT) is defined as the region adjacent to the gross tumor volume, which contains signal abnormalities on T2-weighted or FLAIR sequences. The DTI-FT analysis of the BAT can be adopted as predictive values and a guide for safe tumor resection. This is an observational prospective study on an extensive series of glioma patients who performed magnetic resonance imaging (MRI) with pre-operative DTI-FT analyzed on the BAT by two different software. We examined DTI parameters of Fractional anisotropy (FA mean, min-max), Mean diffusivity (MD), and the shape-metric "tract irregularity" (TI) grade, comparing it with the surgical series' clinical, radiological, and outcome data. The population consisted of 118 patients, with a mean age of 60.6 years. 82 patients suffering from high-grade gliomas (69.5%), and 36 from low-grade gliomas (30.5%). A significant inverse relationship exists between the FA mean value and grading (p = 0.001). The relationship appears directly proportional regarding MD values (p = 0.003) and TI values (p = 0.005). FA mean and MD values are susceptible to significant variations with tumor and edema volume (p = 0.05). TI showed an independent relationship with grading regardless of tumor radiological features and dimensions, with a direct relationship with grading, ki67% (p = 0,05), PFS (p < 0.001), and EOR (p < 0.01). FA, MD, and TI are useful predictive measures of the clinical behavior of glioma, and TI could be helpful for tumor grading identification and surgical planning.

The meaning of life and its relationship to existential anxiety among middle school teachers

The current research aims to identify the meaning of life and its relationship to existential anxiety among middle school teachers. To achieve the research objectives, the researcher adopted the Wong scale to measure the meaning of life, and to build the existential anxiety scale. The researcher applied the two scales to a sample of 308 male and female teachers. The data were then analyzed using the computer program for the Statistical Package for Social Sciences (SPSS). The results were: high level of meaning of life among the research sample, moderate level of existential anxiety among the research sample, no statistically significant differences according to the gender variable (males, females) in each of: meaning of life, existential anxiety, no statistically significant differences according to the variable of academic specialization (scientific specializations and humanities specializations) in each of: meaning of life, existential anxiety, there is a statistically significant inverse relationship between the meaning of life and existential anxiety among middle school teachers. The research concluded by discussing the results and presenting some recommendations and suggestions.

The relationships between dietary inflammatory and antioxidant index with inflammatory markers in children with acute lymphocytic leukemia

Purpose The purpose of this study is to investigate the relationship between dietary total antioxidant capacity (DTAC) and the dietary inflammatory index (DII) with inflammatory status in children recently diagnosed with Acute Lymphoblastic Leukemia (ALL). As the relationship between diet quality scores and inflammation remains uncertain in this population, the authors carried out a hospital-based cross-sectional study. Design/methodology/approach The study used a cross-sectional design involving 54 children recently diagnosed with ALL. Dietary data was collected using a 147-item semi-quantitative food frequency questionnaire developed for the Tehran Lipid and Glucose Study. Inflammatory status was evaluated using various indicators like C-reactive protein (CRP), neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), Glasgow prognostic score (GPS) and Complete blood count-based inflammatory score. Findings The authors found no significant relationship between DII with inflammatory indices and length of hospitalization in patients. However, a significant inverse relationship was observed between the antioxidant indices ferric-reducing ability of plasma, total reactive antioxidant potential and Trolox equivalent antioxidant capacity with the inflammatory index MLR, respectively (ß: −0.19, p = 0.001), (ß: −0.42, p = 0.02), (ß: −0.53, p = 0.005). Also, a significant inverse relationship between FRAP and CRP was observed in the crude model (ß: −0.13, p = 0.05). FRAP was also inversely correlated with GPS and PLR, respectively (ß: −0.08, p = 0.02), (ß: −0.26, p = 0.03). No additional significant links were discovered between food scores and the outcomes studied. Originality/value This study found no link between DII with inflammatory markers or hospitalization duration in children with ALL. However, the authors did observe a noteworthy inverse relationship between DTAC and certain inflammatory markers like MLR. To achieve more dependable findings, further research in this area is necessary.

The relationship of hematologic parameters and lipid profile with acute ischemic stroke

Objective: This study aims to investigate the effect of routine laboratory parameters on clinical outcomes in patients with acute ischemic stroke (AIS). Materials and Methods: Our study was designed as retrospective and cross-sectional. 94 patients with AIS who received inpatient treatment in our clinic with a diagnosis of AIS were included in the study. Laboratory data, demographic, and clinical characteristics were recorded at the time of admission. Neurological disabilities of the patients 3 months after treatment were evaluated with the modified Rankin Scale (mRS). Patients were divided into two groups (good prognosis (mRS 0-2) and poor prognosis (mRS 3-6)). Results:Of the 94 patients included in the study, 47 were men and 47 were women. The mean age was 71.18±11.92 years. Laboratory parameters hemoglobin, eosinophil, triglyceride, total-cholesterol, and ldl-cholesterol values were significantly lower in the group with mRS≥3. As a result of ROC analysis, the area under the curve of hemoglobin, eosinophil, total-cholesterol, ldl-cholesterol, and triglyceride was significantly higher[(AUC: 0.710 95%CI: 0.60-0.81); Sensitivity=67.6%, Specificity=67.9%, p=0.001]. In the multivariable logistic regression model, only the NIHSS score (National Institutes Of Health Stroke Scale Scores) was independently associated with the degree of disability (p=0.001). NIHSS is an independent factor in predicting stroke outcomes. Conclusion: It was determined that there was a significant inverse relationship between the routine laboratory parameters hemoglobin level, eosinophil level, LDL and total cholesterol levels, and infarct volume with the NIHSS scores of hemoglobin and LDL-cholesterol.

9208 Sex Hormones and Abdominal Muscle Area and Radiodensity in Men: A Multi-Ethnic Study of Atherosclerosis

Abstract Disclosure: A. Osmancevic: None. M. Allison: None. I. Miljkovic: None. C. Vella: None. P. Ouyang: None. P. Trimpou: None. B. Daka: None. Context: Information on the associations of testosterone, estradiol and sex hormone binding globulin (SHBG) levels with abdominal muscle volume and quality in men are unclear. Objective: To investigate the association between fasting serum sex hormones and CT-derived abdominal muscle area and radiodensity in adult men. Design: Cross sectional observational study using data from the Multi-Ethnic Study of Atherosclerosis. Participants: A community-based sample of 907 men aged 45-84 years; 878 men with complete data were included in the analysis. Main Outcome Measure(s): CT scans of the abdomen were interrogated for muscle characteristics. Multivariable linear regressions were used to test the associations. Results: After adjustment for age, race/ethnicity, visceral fat, CRP, lifestyle factors, comorbidities and medicine use, higher levels of both total testosterone and estradiol, but not SHBG, were associated with higher abdominal muscle area (B= 1.79, 95% CI 0.1 to 3.4, &amp; B=1.79, 95% CI 0.4 to 3.2, respectively). After the same adjustment, levels of total testosterone showed a significant positive association (B= 0.3, 95% CI 0.0 to 0.6), while a significant inverse relationship was observed for SHBG with abdominal muscle radiodensity (B=-0.34, 95% CI -0.6 to -0.1). Conclusion: Our results indicate significant associations between sex hormones and abdominal muscle characteristics in men from several different race/ethnic groups. These findings reveal novel insights into the previously unrecognized role that SHBG may play in skeletal muscle adipose tissue distribution. Presentation: 6/2/2024

After the same adjustment, levels of total testosterone showed a significant positive association (B= 0.3, 95% CI 0.0 to 0.6), while a significant inverse relationship was observed for SHBG with abdominal muscle radiodensity (B=-0.34, 95% CI -0.6 to -0.1). Conclusion: Our results indicate significant associations between sex hormones and abdominal muscle characteristics in men from several different race/ethnic groups. These findings reveal novel insights into the previously unrecognized role that SHBG may play in skeletal muscle adipose tissue distribution. Presentation: 6/2/2024

9208 Sex Hormones and Abdominal Muscle Area and Radiodensity in Men: A Multi-Ethnic Study of Atherosclerosis

Abstract Disclosure: A. Osmancevic: None. M. Allison: None. I. Miljkovic: None. C. Vella: None. P. Ouyang: None. P. Trimpou: None. B. Daka: None. Context: Information on the associations of testosterone, estradiol and sex hormone binding globulin (SHBG) levels with abdominal muscle volume and quality in men are unclear. Objective: To investigate the association between fasting serum sex hormones and CT-derived abdominal muscle area and radiodensity in adult men. Design: Cross sectional observational study using data from the Multi-Ethnic Study of Atherosclerosis. Participants: A community-based sample of 907 men aged 45-84 years; 878 men with complete data were included in the analysis. Main Outcome Measure(s): CT scans of the abdomen were interrogated for muscle characteristics. Multivariable linear regressions were used to test the associations. Results: After adjustment for age, race/ethnicity, visceral fat, CRP, lifestyle factors, comorbidities and medicine use, higher levels of both total testosterone and estradiol, but not SHBG, were associated with higher abdominal muscle area (B= 1.79, 95% CI 0.1 to 3.4, &amp; B=1.79, 95% CI 0.4 to 3.2, respectively). After the same adjustment, levels of total testosterone showed a significant positive association (B= 0.3, 95% CI 0.0 to 0.6), while a significant inverse relationship was observed for SHBG with abdominal muscle radiodensity (B=-0.34, 95% CI -0.6 to -0.1). Conclusion: Our results indicate significant associations between sex hormones and abdominal muscle characteristics in men from several different race/ethnic groups. These findings reveal novel insights into the previously unrecognized role that SHBG may play in skeletal muscle adipose tissue distribution. Presentation: 6/2/2024

9390 Does Znt8a Have An Association With The Duration Of Diabetes? Case Series And Literature Review

Abstract Disclosure: N.M. Rivera Vargas: None. C.S. Botero Suarez: None. S.K. Suryanarayanan: None. S. Saad-Omer: None. Context: Latent autoimmune Diabetes of adults (LADA) is a form of autoimmune diabetes with features of Type 2 Diabetes but positive autoantibodies resembling Type 1 Diabetes. Latent autoimmune diabetes in adults (LADA), has a mixed phenotype with positive islet-cell antibodies (ICA), glutamic acid decarboxylase autoantibodies (GADA), protein tyrosine phosphatase autoantibodies (IA2A), insulin autoantibodies (IAA), or zinc transporter-8 autoantibodies (ZnT8A). Since the discovery of ZnT8A, the relevance and clinical utility of this marker has sparked interest. Although ZnT8A is used as a complementary diagnostic aid in children, its utility in adults seems to be unclear. Objective: We report a case series of 26 subjects referred to the Orlando VA Endocrine clinic with measured ZnT8A. We hypothesize that higher ZnT8A will be found in adult autoimmune diabetes with newly diagnosed diabetes rather than those with a longer duration of diabetes. We also explore the association between ZnT8A and family history, duration of diabetes, diabetes complications, and C-peptide levels. Method: A case series of 26 adult patients with diabetes mellitus with a positive ZnT8A (≥15 U/mL). We reviewed medical records of these cases to include ZnT8A levels, years of diabetes diagnosis, C-peptide levels, and diabetes complications. Patients were classified into subgroups based on ZnT8A levels into &amp;lt; 350 U/mL or ≥ 350 U/mL. Results: The 26 patients reviewed had a mean (SD) age of 46 (13) years. The mean (SD) duration of diabetes was 16 (12) years, and HbA1C was 8.4 (1.1) %. Poisson regression analysis showed a statistically significant inverse relationship between ZnT8A and years of diabetes (regression coefficient: -0.028; 95% confidence interval: -0.03 to -0.25; p-value &amp;lt;0.001). Diabetic ketoacidosis was present in 35% of subjects, while diabetic neuropathy was noted in 58% of subjects with positive ZnT8A. Patients with a high ZnT8Ab above 350 U/mL displayed a weak trend towards a lower C-peptide mean (p-value 0.42), and lower prevalence of DKA (p-value 0.42) which was not statistically significant. Conclusion: In this case series of patients with adult-onset diabetes, there seems to be a statistically significant inverse relationship between ZnT8A levels and duration of diabetes suggesting a reduction of ZnT8A levels over time. Although limited by a small number of subjects, this may suggest the need for screening with autoantibodies in the setting of diabetes earlier in the disease process. Presentation: 6/2/2024

Government Spending and Industrial Sector Performance in Algeria: Using the ARDL Approach

The study aimed to investigate the impact of government spending on Algeria's industrial sector during the period from 1995 to 2022, with a focus on its effect on the dependent variable. To achieve this, competitive industrial performance was used as an indicator to measure the sector's performance. Additionally, independent variables such as inflation, international oil prices, GDP, and the growth of non-hydrocarbon exports were analysed. The study employed the Auto-Regressive Distributed Lag (ARDL) model to conduct the economic analysis, considering the slow time lags of these variables. The study concluded that there was a positive short-term relationship between government spending and competitive industrial performance in the first year. However, it turned into an inverse relationship in the following year and became insignificant by the third year. In the long term, the study found a significant positive impact of government spending on competitive industrial performance. Additionally, the study identified a significant positive relationship between oil prices and competitive industrial performance, while both inflation and non-hydrocarbon export growth had a significant inverse relationship with competitive industrial performance. The study also found no significant relationship between GDP and competitive industrial performance.
