Depression Symptoms Moderate Associations between Daily Functioning and Neuropsychological Performance in Mexican American Adults.

The influence of depression on the relationship between cognition and daily living in aging Mexican American adults requires further investigation, given projected trends in general growth as well as prevalence of depression and Alzheimer's disease and related dementias (ADRD) in this population. In the present study, we examined the extent to which depression (assessed using the Geriatric Depression Scale - 15 item version) moderated the association between reported daily functioning (assessed using the Functional Activities Questionnaire [FAQ]) and objective neuropsychological performance in aging Mexican American adults in the National Alzheimer's Coordinating Center cohort. Worse reported daily functioning (higher FAQ scores) was associated with worse memory and language performance among participants without elevated depression symptoms (ps < .05), but no associations were observed among those with elevated symptoms (ps > .05). Moreover, depression did not moderate associations of reported daily functioning with performance in attention and working memory or executive functioning and processing speed (ps > .05). Aging Mexican American adults with elevated depression symptoms may have subjective informant reports of daily functioning that are discrepant from their objective performance on formal tests of memory and language. Within the context of neuropsychological evaluations for ADRD, failure to adequately assess mood to inform the nature of cognitive and/or functional changes could result in misdiagnosis and lead to delayed, premature, and/or improper intervention with this population.

Objective: The present study was an observational case control design. The data of study were collected in the period from first of January 2024 to March 2024. The study was conducted from clinical Laboratory private in Hilla City, Babylon province, Iraq. Material and methods: A total number of subjects involved in this study was 150 patients, from both sex (male and female) with age range (5-85). Blood samples were taken from each one to determination lipid profile tests (total cholesterol, total triglyceride, High and Low-density lipoprotein cholesterol and liver function tests (ALT, AST, ALP, TSB) and investigation the correlation between them. Results: The results showed that, these were significant correlation between these tests according to male groups, the strength and direction of the correlation between TC and TG levels. The value being significant suggests that there was a moderate strong relationship between these variables (0.491). A strong positive correlation between TC and LDL levels (0.799), HDL and ALP levels (0.290), ALT and AST levels (0.777). In addition, a positive association between AST and ALP levels (0.125), TC and LDL levels (0.799). On the other hand, a weak negative association TC and AST levels (0.045), TC and TSB levels (-0.185), TG and HDL levels (-0.04). TG and AST levels (-0.065), TG and TSB levels (-0.184), HDL and ALT levels (0.123), HDL and AST levels (-0.133), ALT and TSB levels (-0.08) and between ALP and TSB levels (-0.08). However, a moderate negative association between TG and LDL levels (-0.32) and a very weak negative association between HDL and TSB (-0.016). Conclusion: In male group, a strong positive correlation between TC and LDL levels, HDL and ALP levels, ALT and AST levels. A positive association between AST and ALP levels, TC and LDL levels, these were significant correlation between these tests according to female groups, the strength and direction of the correlation between TC and TG levels, a moderate strong relationship between these variables, TC and LDL levels, ALT and AST levels, ALT and ALP levels, ALT and TSB levels, AST and ALP levels, AST and TSB levels and ALP and TSB levels. And moderately strong negative correlation between HDL and ALT levels. So, a relatively weak positive correlation between LDL and AST levels in female group. Moderately positive correlation between LDL and ALP levels and between LDL and TSB levels.

Exploring Serum Ferritin's Connection to the Acute Phase Response in Zoo-Managed African Rhinoceroses.

Despite serum ferritin's potential as an iron status indicator, its concentrations vary significantly throughout a black rhinoceros's (Diceros bicornis) life, sometimes irrespective of iron load. We explored acute phase response-related biomarkers, serum amyloid A (SAA) and ceruloplasmin (Cp), to better understand the mechanisms influencing serum ferritin changes in managed black rhinoceroses. The objective was to evaluate the relationships between circulating levels of ferritin, SAA, and Cp in black and white rhinoceroses (Ceratotherium simum). We analyzed banked serum samples collected serially from 11 black (n = 222) and 7 white (n = 134), rhinoceroses (rhinos) and classified samples based on SAA values: clinically healthy (< 1 mg/L), subclinical (1-7 mg/L), or clinically abnormal (> 7 mg/L). In black rhinos, serum ferritin was not different between health status categories (p = 0.5292), nor was it correlated with SAA (p = 0.4164). However, Cp activity was significantly lower in clinically healthy sera (p < 0.0001) and had a moderate positive association with SAA (r = 0.477, p < 0.0001). Among the white rhino samples, only five had SAA values greater than 1 mg/L, limiting the assessment of ferritin and Cp activity in the health context. Minor, yet significant, relationships were observed between serum ferritin and Cp activity, negative in black rhinos (r = -0.206; p = 0.0022) and positive in white rhinos (r = 0.289, p = 0.0008). Cp activity may aid in diagnosing illness in black and white rhinos, based on values observed in sera collected near the time of death. However, acute inflammatory processes do not appear to be one of the primary drivers of the high ferritin concentrations detected in some black rhinos.

Exploring Salivary Alpha-Amylase as a Biomarker in Periodontitis: A Comparative Analysis of Disease Stages and Clinical Correlations

Periodontal disease, characterized by bacterial plaque accumulation and subsequent immune response, can lead to gingivitis and periodontitis if untreated. Salivary alpha-amylase (sAA) has emerged as a potential biomarker with implications in periodontal disease progression. Objectives: This study aimed to assess and compare salivary alpha-amylase levels in individuals with periodontitis and healthy controls and to investigate its relationship with clinical parameters of periodontal disease. Forty-five participants were categorized into periodontally healthy (n = 13), Stage I and II Periodontitis (n = 17), and Stage III and IV periodontitis (n = 15) groups. Saliva samples were collected and analyzed using ELISA kits. Statistical analyses included tests for normality, group comparisons, post hoc analysis, and correlation analysis. Significant differences in salivary alpha-amylase levels were observed among severity groups (p &lt; 0.05), with higher levels in periodontitis patients than healthy controls. Spearman correlation revealed moderate positive associations between alpha-amylase levels and probing depth (PD) and clinical attachment loss (CAL). Elevated salivary alpha-amylase levels were found to be associated with more severe periodontal disease, suggesting its potential as a biomarker for periodontitis severity. These findings support the utility of salivary biomarkers in periodontal disease diagnosis and monitoring, although further validation and standardization are warranted for clinical application.

Associations between bedtime media use and sleep outcomes in an adult population-based cohort

Abstract Background We aimed to extend existing research on associations between bedtime media use and sleep in adults by taking relevant covariates into account and testing hypothesised mediating and moderating pathways. Methods Frequency of bedtime media use and sleep outcomes were examined by questionnaire in 4188 adults (59% women, aged 19-94 years) from the Specchio cohort in Geneva, Switzerland. We tested: 1) associations between bedtime media use and sleep (bedtimes, sleep latency, sleep duration, sleep quality, insomnia symptoms, and daytime sleepiness), adjusting for prior sleep, mental health, and health behaviours (physical activity, binge drinking, smoking, total leisure screen time), 2) whether bedtime media use mediates associations between individual susceptibility factors (age, chronotype, and mental health) and sleep, and 3) whether individual susceptibility factors moderate associations between bedtime media use and sleep. Results Often using a screen in the 30 minutes before going to sleep at night was associated with a late bedtime (≥midnight; OR [95% CI]=1.90 [1.44, 2.51], p &amp;lt; 0.001), short sleep duration (&amp;lt;7 hours; 1.21 [1.01, 1.46], p &amp;lt; 0.05), and excessive daytime sleepiness (Epworth score &amp;gt;9; 1.47 [1.25, 1.74], p &amp;lt; 0.001) after adjustment for all covariates. Bedtime media use partly mediated the association between younger age and an evening chronotype and these sleep outcomes. Mental health moderated the association between bedtime media use and sleep quality/insomnia, such that the former was associated with poorer sleep quality/insomnia among individuals with better mental health, but not among those with poorer mental health. Conclusions Frequent bedtime media use was associated with various sleep outcomes, independently of relevant covariates. Limiting the use of screens at bedtime is important to promote sleep among adults. Individuals with poorer mental health likely require additional support to improve their sleep quality. Key messages • Frequent bedtime media use is associated with a late bedtime, short sleep duration, and more daytime sleepiness in adults, and these associations hold after adjustment for relevant covariates. • Frequent bedtime media use mediates the association between individual susceptibility factors and sleep outcomes. Mental health moderates the association between bedtime media use and sleep quality.

Urinary N-acetylglucosaminidase in People Environmentally Exposed to Cadmium Is Minimally Related to Cadmium-Induced Nephron Destruction

Exposure to even low levels of the environmental pollutant cadmium (Cd) increases the risk of kidney damage and malfunction. The body burden of Cd at which these outcomes occur is not, however, reliably defined. Here, multiple-regression and mediation analyses were applied to data from 737 non-diabetic Thai nationals, of which 9.1% had an estimated glomerular filtration rate (eGFR) ≤ 60 mL/min/1.73 m2 (a low eGFR). The excretion of Cd (ECd), and renal-effect biomarkers, namely β2-microglobulin (Eβ2M), albumin (Ealb), and N-acetylglucosaminidase (ENAG), were normalized to creatinine clearance (Ccr) as ECd/Ccr Eβ2M/Ccr, Ealb/Ccr, and ENAG/Ccr. After adjustment for potential confounders, the risks of having a low eGFR and albuminuria rose twofold per doubling ECd/Ccr rates and they both varied directly with the severity of β2-microglobulinuria. Doubling ECd/Ccr rates also increased the risk of having a severe tubular injury, evident from ENAG/Ccr increments [POR = 4.80, p = 0.015]. ENAG/Ccr was strongly associated with ECd/Ccr in both men (β = 0.447) and women (β = 0.394), while showing a moderate inverse association with eGFR only in women (β = −0.178). A moderate association of ENAG/Ccr and ECd/Ccr was found in the low- (β = 0.287), and the high-Cd body burden groups (β = 0.145), but ENAG/Ccr was inversely associated with eGFR only in the high-Cd body burden group (β = −0.223). These discrepancies together with mediation analysis suggest that Cd-induced nephron destruction, which reduces GFR and the tubular release of NAG by Cd, involves different mechanisms and kinetics.

Distributed parameter model of dynamic contrast-enhanced MRI in the identification of IDH mutation, 1p19q codeletion, and tumor cell proliferation in glioma patients

ObjectivesTo investigate the clinical value of hemodynamic parameters derived from dynamic contrast-enhanced MRI (DCE-MRI) in predicting glioma genotypes including isocitrate dehydrogenase (IDH) mutation, 1p/19q codeletion status and the tumor proliferation index (Ki-67) noninvasively. And to compare the diagnostic performance of parameters of distributed parameter (DP)model and extended Tofts (Ex-Tofts) model.Materials and methodsDynamic contrast-enhanced MRI (DCE-MRI) data of patients with glioma were prospectively enrolled from April 2021 to May 2023. The imaging data were analyzed using DP and Ex-Tofts model for evaluating the perfusion and permeability characteristics of glioma. Comparisons were performed according to IDH genotype in all glioma patients and 1p/19q codeletion in IDH mutation glioma patients. Receiver operating characteristic (ROC) curves were generated for DCE-MRI parameters. The Spearman rank correlation coefficients were calculated between DCE MRI parameters and Ki-67 index.ResultsIn IDH-mutation gliomas, a higher blood flow (F) was found in 1p/19q codeletion gliomas than in 1p/19q intact gliomas. No parameter derived from Ex-Tofts model showed significant differences in predicting 1p/19q status. Fractional volume of interstitial space (Ve) derived from both the DP and Ex-Tofts models exhibited optimal performance in predicting IDH genotype (AUC = 0.818, 0.828, respectively). Ve also showed the highest correlations with Ki-67 LI within their respective models in all gliomas (ρ = 0.62, 0.61), indicating comparable moderate positive associations. Ki-67ConclusionDP model showed a clear advantage in predicting 1p/19q status compared to Ex-Tofts model. The DP and Ex-Tofts models performed similarly in predicting IDH mutation and Ki-67 index.

Correlation of Pre-Operative Myo-Inositol/Creatine Ratio with Histopathological Grade of Glioma

Background: Introduction: Gliomas are the most frequent primary intracerebral tumors in adults &amp; constitute 35–50% of all intracranial neoplasms. In determining a treatment plan, tumor grade is a key consideration for minimizing the risk of unnecessary morbidity and mortality. Objective: To evaluate Correlation of pre-operative Myo-inositol/Creatine ratio with histopathological grade of glioma. Materials and method: This was a cross sectional experimental study. Total 33 patients consistent with selection criteria were enrolled in this study. Myo-inositol/ Creatine ratio was obtained from MRS. Histopathological grade of glioma was obtained from biopsy (hematoxylin and eosin stain or HE stain) report. The obtained results were then grouped categorically. Result: Out of 33 patients, 22 were male and 11 were female. According to histopathology, 14 gliomas were confirmed as high grade and 19 gliomas were confirmed as low grade. Spearman Rank Correlation Test showed a moderate negative association between Myo-inositol/Creatine ratio with glioma grading with coefficient value of r = -0.611 with a statistically significant p-value (p&lt;0.001). We were able to differentiate between low grade (II) and high grade (III + IV) gliomas using the Myoinositol/ Creatine ratio. The levels of MI/Cr were higher (e”0.48) in patients with lowgrade glioma, and lower (&lt;0.48) in patients high grade glioma Conclusion: This study has shown a significant correlation between pre-operative Myo-inositol/Creatine ratio with histopathological grade of glioma. It may help neurosurgeons in taking clinical decisions about patient management and counselling. Bang. J Neurosurgery 2024; 13(2): 57-63

Habitual water intake impacted the body composition of young male athletes in free-living conditions: a cross-sectional study

The study aimed to explore the associations between water intake and body composition and differences of body composition in different water itake and hydration statuses among young male athletes. A cross-sectional study was conducted among 111 young male athletes in Beijing, China. Total drinking fluids (TDF) and water from food were assessed using a 7-day, 24-h fluid intake record questionnaire and the duplicate portion method, respectively. The osmolality of 24-hour urine and blood samples was tested. Body composition was measured using a bioelectrical impedance analyzer twice at 5-min intervals. Participants were divided into two groups based on the recommendations of total water intake (TWI) and TDF in China, as well as into three groups based on 24-h urine osmolality. Pearson's correlation coefficients were calculated to determine the relationship between water intake and body composition. Chi-square tests and Student's t-tests were used to compare differences. A total of 109 participants completed the study. TDF (r = 0.230, p = 0.016; r = 0.234, p = 0.014; r = 0.242, p = 0.011) and TWI (r = 0.275, p = 0.004; r = 0.243, p = 0.011; r = 0.243, p = 0.011) were positively correlated with total body water (TBW), intracellular water (ICW), and extracellular water (ECW). TBW/body weight (BW) was positively associated with TDF percentage of BW (TDF/BW) (r = 0.267, p = 0.005), water from food percentage of BW (r = 0.217, p = 0.024), and TWI percentage of BW (TWI/BW) (r = 0.316, p = 0.001). Participants who met the TDF recommendation of China had 1.3 kg higher skeletal muscle mass (SMM), 0.9 kg higher ICW, and 0.5% higher TBW/BW than those who did not (all p &amp;lt; 0.05), with fat-free mass (FFM) and TBW being higher (p = 0.051; p = 0.050). Those who met the TWI recommendation of China had 1.3 kg higher SMM, 2.4 kg higher FFM, 1.1 kg higher ICW, 0.6 kg higher ECW, and 1.7 kg higher TBW than their counterparts (all p &amp;lt; 0.05). Moderate associations were found between water intake and body composition. No significant differences were observed among participants in three hydration statuses (all p &amp;gt; 0.05). Participants who met the TWI or TDF recommendations had better body composition distribution than their counterparts. Thus, habitual water intake, not hydration status, affects body composition among athletes in free-living conditions.

Context matters: The importance of investigating random effects in hierarchical models for early childhood education researchers

This paper highlights the importance of examining individual, classroom, and school-level variables simultaneously in early childhood education research. While it is well known that Hierarchical Linear Modeling (HLM) in school-based studies can be used to account for the clustering of students within classrooms or schools, less known is that HLM can use random effects to investigate how higher-level factors (e.g., effects that vary by school) moderate associations between lower-level factors. This possible moderation can be detected even if higher-level data are not collected. Despite this important use of HLM, a clear resource explaining how to test this type of effect is not available for early childhood researchers. This paper demonstrates this use of HLM by presenting three analytic examples using empirical early childhood education data. First, we review school-level effects literature and HLM concepts to provide the rationale for testing cross-level moderation effects in education research; next we do a short review of literature on the variables that will be used in our three examples (viz., teacher beliefs and student socioemotional behavior); next we describe the dataset that will be analyzed; and finally we guide the reader step-by-step through analyses that show the presence and absence of fixed effects of teacher beliefs on student social outcomes and the erroneous conclusions that can occur if school-level moderation (i.e., random effects) tests are excluded from analyses. This paper provides evidence for the importance of testing for how teachers and students impact each other as a function of school differences, shows how this can be accomplished, and highlights the need to examine random effects of clustering in educational models to ensure the full context is accounted for when predicting student outcomes.

Response to tigilanol tiglate in dogs with mast cell tumors.

Information regarding response rate to tigilanol tiglate for mast cell tumors in dogs is limited. Report the response rate and durability of tigilanol tiglate intratumoral treatment in dogs with mast cell tumors presented to veterinary oncologists. One hundred forty-nine dogs; 151 individual tumors. Multicenter, retrospective survey-based study. Veterinary oncologists subscribed to the American College of Veterinary Internal Medicine (ACVIM) oncology listserv were solicited for information from dogs treated with tigilanol tiglate. An electronic survey was used to collect information at initial treatment, 1 month and 1 year after treatment. Most tumors were cutaneous, occurred on the limbs and were cytologically low grade. Seventy-five percent of dogs achieved a complete response after 1 dose of tigilanol tiglate 1 month after treatment. This response was durable at 1 year in 64% of dogs for which data were available (n = 88). Wound formation, an expectation after treatment, occurred after a median of 7 days (range, 1-91 days), with a median wound area of 4.71 cm2 (range, 0.09-100 cm2). Wounds took a median of 30 days to heal completely (range, 14-154 days). A moderate association between tumor volume and wound size was confirmed. Tigilanol tiglate is an effective local treatment option for mast cell tumors in dogs with a predictable clinical course and response. Because of the unique mode of action and clinical course, client education and careful case selection is necessary before electing tigilanol tiglate for local treatment.

Comparisons and associations of psychological factors and the number of painful sites in wheelchair basketball athletes with and without shoulder pain: A cross-sectional case-control study

Objective To compare psychological factors and the number of painful sites between wheelchair basketball athletes (WBA) with and without shoulder pain and examine their associations with shoulder pain. Design A cross-sectional, case-control study. Methods Forty-three WBA participated. Shoulder pain was assessed with the Wheelchair User's Shoulder Pain Index (WUSPI), pain catastrophizing with the Pain Catastrophizing Scale (PCS), kinesiophobia by the Tampa Kinesiophobia Scale (TKS), self-efficacy with the General Self-Efficacy Scale (GSES), and the number of painful sites using the Nordic Musculoskeletal Questionnaire. Disability and sport-related data were collected. Spearman’s correlation coefficients were calculated. Mann-Whitney U and independent samples t-tests were used for between-group comparisons. Results Athletes with shoulder pain (n = 21) had an increased number of painful sites (P < .050) and higher PCS (P = .003). The WUSPI exhibited moderate associations with the number of painful sites during the last year (rho = .581) and past seven days (rho = .602), and PCS (rho = .470), and a weak association with the TKS (rho = .333)(P < .050). The number of painful sites with disability exhibited moderate associations with PCS (rho = .427) and GSES (rho = –.473)(P < .050). WBA classification levels showed moderate associations with the WUSPI (rho = –.400) and the number of painful sites during the last year (rho = –.437), and a weak association with the number of painful sites during past seven days (rho = –.315)(P < .050). The PCS showed weak associations with the number of painful sites during the last year (rho = .365) and the past seven days (rho = .398)(P < .050). Conclusions Results suggest considering WBA classes, pain catastrophizing, self-efficacy and multisite pain in the pain management of WBA.

Variation in Relative Risk Perceptions and Tobacco Use by Race and Socioeconomic Status among Older Adults who Smoke: Evidence from the Population Assessment of Tobacco and Health (PATH) Study.

Older adults who smoke face significant risk of tobacco-related disease and hold misperceptions about health risks posed by nicotine product use. This study examined whether socioeconomic status and race are associated with variation in cigarette/e-cigarette relative risk perceptions, whether relative risk perceptions are associated with tobacco use behaviors, and whether socioeconomic status and race moderate associations between perceptions and use behaviors. Five waves of PATH Study yielded data from 1,879 adults >55 who smoked within the past 30 days during Wave 1. Adjusted longitudinal logistic models estimated associations between higher vs. lower SES ("low-SES": less than high school diploma/GED. and annual household income<$25,000) and race (White vs. Black/African American; AA) and e-cigarette/cigarette relative risk perceptions, behavioral intentions, and e-cigarette use. Lower-SES adults were more likely to report e-cigarettes were very/extremely harmful to health (AOR: 1.74, p<0.01) and less likely to report e-cigarettes were less harmful than cigarettes (AOR: 0.65, p<0.01). Black/AA adults were less likely to report that e-cigarettes were less harmful than cigarettes. Participants rating e-cigarettes as equally/more harmful than cigarettes exhibited lower odds of intending to quit smoking or switch to e-cigarettes. Finally, Black/AA adults who also perceived e-cigarettes equally/more harmful than cigarettes exhibited greater odds of trying to reduce rather than quit smoking (AOR: 1.58, p=0.02). Many older adults who smoke perceive e-cigarettes as equally or more harmful than cigarettes, particularly low-SES and Black/AA older adults. Differences in relative risk perceptions among high priority populations could negatively influence cessation attempts and switching behaviors. This study found that Black/AA and low-SES older adults who smoke cigarettes were more likely to perceive e-cigarettes as harmful or more harmful than cigarettes. The absence of accurate, evidence-based information regarding the relative health risks associated with the long-term use of various tobacco products may impede policy efforts to reduce disparities in smoking-related disease through increased cessation and/or harm reduction.

The impact of social media screen-exposure time on suicidal ideation among Pakistani adolescents.

Adolescence is a crucial life stage for the individual identity formation. The growing employment of social media and screen-exposure among teenagers and the concerning rise in suicide ideation rates in this susceptible group both suggested this study. Thus, we explored the association between adolescents' suicidal ideation and their daily social media screen-exposure. We surveyed 502 students, aged 13 to 19 years old, recruited in colleges and universities of Punjab, Pakistan. The survey was based on a 28-item self-reported questionnaire and demographic data collection. Approximately 40% of adolescents reporting suicidal ideation showed an extended social media screen-exposure, as well as significant depressive feelings and problematic personality traits. In particular, suicidal ideation increased by 0.39 for each one-unit increase in screen-exposure time and levels of depression increased by 0.21 times by unit of screen-exposure. The correlation coefficients further indicated a moderate positive association between depression and suicidal thoughts as well as personality traits played as mediators between social media screen-exposure time and suicidal ideation among adolescents. Our study found a positive association, even if modest, between the use of social media screens and suicidal ideation among adolescents. This evidence may suggest to adopt specific strategies to address the use of media among youths and prevent mental disorders related to the prolonged and inappropriate use of digital technologies in those users with a vulnerable personality.

APX2009 sensitizes hypoxic breast cancer cells to doxorubicin by increasing its accumulation and caspase-3/7-mediated apoptosis.

The association of targeted therapy with chemotherapy is encouraged to increase the treatment efficiency, especially in hypoxic triple-negative breast cancer. The APE1 redox activity has stood out as a potential tumor target. However, the effect of the association of the APE1 redox inhibitors with doxorubicin in hypoxia still needs to be evidenced. Therefore, our objective was to investigate the effect of the APX2009 (APE1 inhibitor) on the sensitization of breast cancer cells to doxorubicin in normoxia and hypoxia. The WST-1 assay was used to evaluate cell viability after APX2009 and doxorubicin application under normoxia and hypoxia conditions in the MCF-7 and MDA-MB-231 cells. Apoptosis was analyzed by annexin assay and detection of caspases-3/7 activity by luminescence-based assay. The clinical association between APE1 inhibition signature and doxorubicin sensitivity was evaluated by bioinformatics analyses. MDA-MB-231 and MCF-7 cell lines were more sensitive to APX2009 in normoxia than in hypoxia. Co-treatment with APX2009 and doxorubicin in hypoxia further decreased the viability of triple-negative MDA-MB-231 cells than treatment alone, which was accompanied by doxorubicin intracellular accumulation, and increase of apoptotic cells percentage, and caspases-3/7 activity. Moderate association was found between APE1 inhibition signature and doxorubicin sensitivity in the hypoxic basal subtype. The findings suggest that APX2009 sensitizes the MDA-MB-231 cells to doxorubicin in hypoxia by doxorubicin intracellular accumulation and caspases-3/7-mediated apoptosis.

Do adverse childhood experiences increase the risk of postpartum traumatic stress and depression?

This study was conducted to determine the effect of childhood adverse experiences on the risk of postpartum posttraumatic stress disorder (PP-PTSD) and postpartum depression (PPD). This descriptive study was conducted with 417 mothers between 1 March and 30 April 2022. Data were collected using a demographic and obstetric information form, the Adverse Childhood Experiences Questionnaire (ACE), City Birth Trauma Scale (CityBiTS) and Edinburgh Postpartum Depression Scale (EPDS) through the Google Forms platform. The mothers participating in the study had a mean age of 30.47 ± 4.21 years, 65.9% (n = 275) had at least one ACE, 10.3% (n = 43) met all of the DSM-5 PTSD criteria according to the CityBiTS, and 91.8% (n = 383) had at least one traumatic stress symptom. Correlation analysis revealed weak positive associations between number of ACEs and CityBiTS score (p < 0.001, r = 0.328) and EPDS score (p < 0.001, r = 0.291) and a moderate positive association between CityBiTS and EPDS scores (p < 0.001, r = 0.601). PP-PTSD was found to be a partial mediator variable between ACE and PPD. The presence of ACE in mothers was found to increase the risk of developing PPD, both alone and when combined with traumatic birth experience. Therefore, we believe that screening for a history of ACE during pregnancy, investigating traumatic birth experiences in the postpartum period, closer follow-up of mothers with both ACE and traumatic birth experiences and increasing support systems will be beneficial in the prevention and early diagnosis of PPD.

Balance and Walking Speed Outcomes in Individuals Receiving Inpatient Rehabilitation for Acute Cerebellar Stroke.

Cerebellar strokes account for only 2-3% of all strokes occurring annually in the United States but represent a disproportionally higher share of morbidity and mortality. Evidence examining the effect of inpatient rehabilitation on functional outcomes following a cerebellar stroke is limited. This study aimed to examine the effects of inpatient rehabilitation on balance and walking speed in individuals with cerebellar stroke. A secondary purpose of this study was to examine the length of inpatient rehabilitation stay of the included patients. A retrospective analysis was conducted using review of patient records during their inpatient rehabilitation stay from January 2021 to February 2022 at a large hospital system in the southeast United States. Balance and gait outcomes were examined on admission and discharge from inpatient rehabilitation that included physical therapy interventions. A paired t-test examined for changes in outcomes from admission to discharge. Pearson correlation examined for the association between length of stay and outcomes. A total of 15 records were reviewed. There were significant improvements in the Berg Balance Scale (BBS), Postural Assessment Scale for Stroke (PASS), and the 10-Meter Walk Test (10MWT) (p's < 0.01) from admission to discharge with large effect sizes (range d = 0.70-1.67) following inpatient rehabilitation. The average length of stay was 12.67 days (SD = 6.5) and the mean total hours of combined occupational, physical, and speech therapy was 27.33 (SD = 6.52) h. There was a moderate association between length of stay and PASS (r = 0.525, p = 0.04) and BBS (r = 0.546, p = 0.04) outcomes. Patients who underwent inpatient rehabilitation following acute cerebellar strokes demonstrated improvements in balance and gait speed. Study results could assist clinicians designing interventions for patients with cerebellar strokes in the inpatient rehabilitation setting.

There are multiple clocks that time us: Cross-sectional and longitudinal associations among 14 alternative indicators of age and aging.

Aging is a complex process influenced by mechanisms operating at numerous levels of functioning. Multiple biomarkers of age have been identified, yet we know little about how the different alternative age indicators are intertwined. In the Berlin Aging Study II (nmin= 328; nmax= 1,517, women = 51%; 14.27 years of education), we examined how levels and seven-year changes in indicators derived from blood assays, MRI brain scans, other-ratings, and self-reports converge among older adults. We included eight epigenetic biomarkers (incl. five epigenetic "clocks"), a BioAge composite from clinical laboratory parameters, brain age, skin age, subjective age, subjective life expectancy, and future health horizon. We found moderate associations within aging domains, both cross-sectionally and longitudinally over seven years. However, associations across different domains were infrequent and modest. Notably, participants with older BioAge had correspondingly older epigenetic ages. Our results suggest that different aging clocks are only loosely interconnected and that more specific measures are needed to differentiate healthy from unhealthy aging.

A clinical outcomes data archive for a comprehensive fetal diagnosis and treatment center.

Data on near and long-term outcomes are critical for the care of all maternal-fetal patients presenting to a fetal center. This is important since physiologic and neurodevelopmental attributes do not manifest until childhood when multi-level factors influence health outcomes. Electronic health records (EHR) documentation structures are not designed for acquisition of key attributes, and changes over time and between-clinician differences can affect resultant output. Therefore, EHR derived datasets have limited ability to accurately characterize the clinical presentation and care trajectory of patients with congenital anomalies. Moreover, the fetus lacks a digital identity and requires relinking attributes documented in the maternal chart to those in the pediatric EHR. This conundrum amplifies in the setting of multiple gestation, returning maternal patients, and pregnancies with fetal demise. Current data systems result in incomplete abstraction of variables that may confound, mediate, or moderate critical associations. Our objective was to develop and implement a prospective data capture platform to transform EHR data into an analytic-grade database for multi-purpose use. A unified platform for longitudinal follow-up of maternal-child dyads named the Clinical Outcomes Data Archive (CODA) was constructed. CODA was designed using a data dictionary based on multidisciplinary input, a relational identity for each patient, fetus, and pregnancy, and a process by which EHR-sourced and chart-abstracted data are validated. Descriptive analyses were performed for data acquired between July 2022 - July 2023, and a comparison of studies before and after implementation of CODA is presented. 5,394,106 data points were validated for 7,662 patients across 12 conditions. 2% of data points were found to be unreliable or undocumented. 91% of data points were sourced from the EHR. 85% of condition-specific variables required manual chart abstraction. The study conducted with CODA contributed to 18 studies. CODA successfully merges EHR-sourced and manually abstracted documentation for longitudinal study of the maternal-child dyad.

Mid- to long-term radiological and respiratory outcomes following surgery for older early-onset scoliosis patients with Marfan syndrome

This study aimed to elucidate mid- to long-term radiological and respiratory outcomes in patients aged 7–11 years at index surgery with Marfan syndrome and early-onset scoliosis (EOS) in a retrospective multicenter study. Primary outcomes were final thoracic height and final percentage of predicted vital capacity (%VC) at or after 16 years of age. We identified 21 (6 male and 15 female) patients with a mean age of 9.9 years and mean follow-up period of 149.3 months. Fifteen patients underwent primary fusion, whereas six underwent growth-friendly surgery (GFS). The mean preoperative and final T1–T12 heights were 204.0 mm and 248.0 mm, respectively. Final pulmonary function tests were available for 16 patients, and the mean final %VC was 54.0% with 10 patients exhibiting a final %VC < 60%. A significant moderate association was observed between the final T1–T12 height and final %VC. The predicted final T1–T12 height required for a final %VC of 60% was approximately 260 mm. Although most older patients with Marfan syndrome and EOS acquired a considerably large final T1–T12 height, a larger thoracic height was required for satisfactory respiratory function in many cases; hence, GFS may be indicated even in this population.
