UNASSIGNED: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become the most common chronic liver disease worldwide and is increasingly being diagnosed at younger ages, affecting more than one-third of young people with obesity.
UNASSIGNED: To evaluate associations between perinatal conditions and risk of MASLD and associated progressive liver disease.
UNASSIGNED: This nationwide, population-based case-control study included all biopsy-confirmed cases of MASLD in Sweden. Individuals aged 25 years or younger (hereafter, young individuals) with biopsy-proven MASLD between January 1, 1992, and December 31, 2016, were matched to up to 5 general population control individuals. Granular data on maternal and perinatal characteristics were retrieved from the Swedish Medical Birth Register. Data were analyzed from June 2023 to June 2024.
UNASSIGNED: Birth weight (low [<2500 g], reference [2500 to <4000 g], or high [≥4000 g]), gestational age (GA), and birth weight for GA (small for GA [SGA; <10th percentile], appropriate for GA [10th-90th percentile], or large for GA [LGA; >90th percentile]), compared between patients and matched controls.
UNASSIGNED: The main outcome was odds of biopsy-proven MASLD and MASLD-associated progressive liver disease (ie, liver fibrosis or cirrhosis) according to birth weight, GA, and birth weight for GA, adjusted for matching factors.
UNASSIGNED: In total, 165 young individuals with biopsy-proven MASLD (median age at diagnosis: 12.0 years [IQR, 4.4-16.9 years]; 100 [60.6%] male) were matched with 717 controls. There was an association between low birth weight and future development of MASLD (adjusted odds ratio [AOR], 4.05; 95% CI, 1.85-8.88) but no association between high birth weight and odds of MASLD (AOR, 0.64; 95% CI, 0.38-1.08) compared with the reference birth weight. An association was seen for SGA (AOR, 3.36; 95% CI, 2.00-5.64) compared with appropriate size for GA (reference category) but not for LGA (AOR, 0.57; 95% CI, 0.27-1.20). Progressive liver disease was more common in individuals born with low birth weight (AOR, 6.03; 95% CI, 1.66-21.87) or SGA (AOR, 4.90; 95% CI, 2.15-11.14).
UNASSIGNED: In this nationwide study of young individuals with biopsy-proven MASLD, low birth weight and SGA were associated with development of MASLD and progressive liver disease, suggesting a need for structured screening measures to diagnose these conditions early in high-risk individuals.

BACKGROUND: Preeclampsia is a unique vascular disease during pregnancy that generally appears after 20 of weeks gestation or until 6 weeks after delivery. Left undiagnosed, preeclampsia can lead rapidly to death of both mother and fetus.
OBJECTIVE: To verify the efficacy of peripheral blood inflammatory markers (BIMs)in diagnosing preeclampsia and compare them with results from other studies.
METHODS: Our retrospective case-control study comprised two patient groups. Pregnant women with preeclampsia and pregnant women without preeclampsia were compared for BIMs: neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and mean platelet volume (MPV). The primary endpoint of our research was to assess the predictive power of BIMs for preeclampsia diagnosis.
RESULTS: The sample size was calculated based on expected differences of BIMs between the control and study groups. Comparison of quantitative variables was conducted with independent sample t-test or alternatively by Wilcoxon rank sum test. The MPV values were slightly higher in the preeclampsia group, but not statistically significant. NLR and PLR did differentiate between study and control groups.
CONCLUSIONS: The diagnostic accuracy of BIMs is unsatisfactory for preeclampsia diagnosis. Discrepancies concerning these values need to be clarified. Further large prospective studies are necessary to validate the potential factor accuracy in preeclampsia diagnosis.

UNASSIGNED: To determine the misclassification rate of the keratoconus percentage (KISA%) index efficacy in eyes with progressive keratoconus.
UNASSIGNED: This was a retrospective case-control study of consecutive patients with confirmed progressive keratoconus and a contemporaneous normal control group with 1.00 diopters or greater regular astigmatism. Scheimpflug imaging (Pentacam HR) was obtained for all patients. KISA% index and inferior-superior (IS) values were obtained from the Pentacam topometric/keratoconus staging map. Receiver operating characteristic curves were generated to determine the area under the receiver operating characteristic curve (AUROC), sensitivity, and specificity values.
UNASSIGNED: There were 160 eyes from 160 patients evaluated, including 80 eyes from 80 patients with progressive keratoconus and 80 eyes from 80 control patients. There were 20 eyes (25%) with progressive keratoconus misclassified by the KISA% index, with 16 eyes (20%) of the progressive keratoconus cohort classified as normal (ie, KISA% < 60). There were 4 eyes (5%) with progressive keratoconus that would classify as having \"normal topography\" using the published criteria for very asymmetric ectasia with normal topography of KISA% less than 60 and IS value less than 1.45. All controls had a KISA% index value of less than 15. The optimal cut-off value to distinguish cohorts was 15.31 (AUROC = 0.972, 93.75% sensitivity). KISA% index values of 60 and 100 achieved low sensitivity (80% and 73.75%, respectively).
UNASSIGNED: The KISA% index misclassified a significant proportion of eyes with progressive keratoconus as normal. Although highly specific for clinical keratoconus, the KISA% index lacks sensitivity, does not effectively discriminate between normal and abnormal topography, and thus should not be used in large data analysis or artificial intelligence-based modeling.

BACKGROUND: Sarcopenia is common in children after liver transplantation (LTx). Resistance training (RT) may be effective in combating sarcopenia.
OBJECTIVE: The purpose of the study was to test the feasibility and impact of a 12-week RT program on skeletal muscle mass (SMM), muscle strength, physical performance (PP), and child-parent perspectives about RT.
METHODS: Children (6-18 years) post-LTx and healthy controls (HC) underwent progressive RT using resistance bands. SMM and adipose tissue (MRI: abdomen and thigh), muscle strength (handgrip, push-ups, sit-to-stand), and PP (6-minute walk test [6MWT], timed-up-and-down-stair test [TUDS]) were measured before and after 12-weeks of RT.
RESULTS: Ten children post-LTx (11.9 ± 3.5 years) and 13 HC (11.7 ± 3.9 years) participated. LTx children significantly increased abdominal SM-index (+4.6% LTx vs. a -2.7% HC; p = 0.01) and decreased visceral adipose tissue-index (-18% LTx vs. -0.8% HC; p = 0.04) compared to HC. No thigh SMI changes were noted. Significant increases in 6MWT distance (LTx; p = 0.04), number of push-ups (p = 0.04), and greater reduction times for TUDS (-10.6% vs. +1.7%; p = 0.05) occurred after 12 weeks. Higher thigh muscle-fat content was associated with worse physical performance. These results were impacted by adherence (≥75% vs. <75%) and family engagement.
CONCLUSIONS: RT in children post-LTx is feasible and effective. RT in children post-LTx may alleviate adverse outcomes associated with sarcopenia.

OBJECTIVE: This study investigated whether kidney transplant donors experience increased arterial stiffness compared with the general population and how arterial stiffness changes over time.
METHODS: Our study included 59 kidney transplant donors and 27 healthy volunteers. All subjects underwent cardio-ankle vascular index measurements. We studied fibroblast growth factor23, klotho, monocyte chemoattractant protein-1, N-terminal pro-B-type natriuretic peptide, indoxyl sulfate, and p-cresyl sulfate levels.
RESULTS: Cardio-ankle vascular index level was higher in donors 6 to 11 years after donation (8.02 ± 0.24 m/s) than in donors 2 to 6 years after donation (7.02 ± 0.27 m/s) and healthy volunteers (6.65 ± 0.22 m/s). Cardioankle vascular index level was positively correlated with age (r = 0.382, P < .001) and levels of triglyceride (r = 0.213, P = .049), blood urea nitrogen (r = 0.263, P = .014), creatinine (r = 0.354, P = .001), calcium (r = 0.228, P = .035), indoxyl sulfate (r = 0.219, P = .042), p-cresyl sulfate (r = 0.676, P ≤ .001), and monocyte chemoattractant protein-1 (r = 0.451, P ≤ .001) and negatively correlated with estimated glomerular filtration rate (r = -0.383, P < .001). Multiple linear regression analysis revealed that age (P = .026, B = 0.244), mean arterial blood pressure (P < .001, B = 0.446), blood urea nitrogen (P = .006, B = 0.302), creatinine (P = .032, B = 0.236), estimated glomerular filtration rate (P = .003, B = -0.323), fibroblast growth factor-23 (P = .007, B = 0.294), N-terminal pro-B-type natriuretic peptide (P = .005, B = 0.304), and monocyte chemoattractant protein-1 (P ≤ .001, B = 0.434) independently predicted cardio-ankle vascular index levels.
CONCLUSIONS: Even without additional risk factors, kidney donors should be followed closely for arterial stiffness and cardiovascular disease, especially in the long-term (>5 years) after kidney transplant.

Genetic polymorphisms have been linked to the differential waning of vaccine-induced immunity against COVID-19 following vaccination. Despite this, evidence on the mechanisms behind this waning and its implications for vaccination policy remains limited. We hypothesize that specific gene variants may modulate the development of vaccine-initiated immunity, leading to impaired immune function. This study investigates genetic determinants influencing the sustainability of immunity post-mRNA vaccination through a genome-wide association study (GWAS). Utilizing a hospital-based, test negative case-control design, we enrolled 1,119 participants from the Taiwan Precision Medicine Initiative (TPMI) cohort, all of whom completed a full mRNA COVID-19 vaccination regimen and underwent PCR testing during the Omicron outbreak. Participants were classified into breakthrough and protected groups based on PCR results. Genetic samples were analyzed using SNP arrays with rigorous quality control. Cox regression identified significant single nucleotide polymorphisms (SNPs) associated with breakthrough infections, affecting 743 genes involved in processes such as antigenic protein translation, B cell activation, and T cell function. Key genes identified include CD247, TRPV1, MYH9, CCL16, and RPTOR, which are vital for immune responses. Polygenic risk score (PRS) analysis revealed that individuals with higher PRS are at greater risk of breakthrough infections post-vaccination, demonstrating a high predictability (AUC = 0.787) in validating population. This finding confirms the significant influence of genetic variations on the durability of immune responses and vaccine effectiveness. This study highlights the importance of considering genetic polymorphisms in evaluating vaccine-induced immunity and proposes potential personalized vaccination strategies by tailoring regimens to individual genetic profiles.

Pain is a widespread and troubling clinical and social problem with important effects on society and individuals. The purpose is to assess the relationship between pain and eating behavior, macro-micronutrient intake, and dietary inflammation index. The study was carried with a total of 80 patients, consisting of 40 patients diagnosed with pain and 40 patients not diagnosed with pain, who applied to a private hospital in Istanbul as outpatients with a questionnaire face-to-face consisting of questions about sociodemographic characteristics, anthropometric measurements, pain-related information, Eating Attitude Test (EAT-19), and 24-hour food consumption record. The statistical analysis of the data was conducted with SPSS v27 package program. People who had pain had higher levels of disrupted eating attitudes than those who did not have pain. The \"Bulimia\" subfactor mean score of the EAT-19 was higher in those with pain (P < .05). No difference was found between the case-control groups regarding the mean dietary inflammation index (DII) score and energy, macro- and micronutrient consumption values (P > .05). No difference was detected between the case-control groups with disrupted eating attitudes regarding the median DII score (P > .05). The median DII score was significantly higher in individuals with pain and normal eating attitudes than in those without pain and with disrupted eating attitudes (P < .05). There is a relationship between pain, eating attitudes, and DII, the median DII score of those who had pain and had normal eating attitudes was higher.

BACKGROUND: Autism and schizophrenia spectrum disorders (SSDs) both feature atypical social cognition. Despite evidence for comparable group-level performance in lower-level emotion processing and higher-level mentalizing, limited research has examined the neural basis of social cognition across these conditions. Our goal was to compare the neural correlates of social cognition in autism, SSDs, and typically developing controls (TDCs).
METHODS: Data came from two harmonized studies in individuals diagnosed with autism or SSDs and TDCs (aged 16-35 years), including behavioral social cognitive metrics and two functional magnetic resonance imaging (fMRI) tasks: a social mirroring Imitate/Observe (ImObs) task and the Empathic Accuracy (EA) task. Group-level comparisons, and transdiagnostic analyses incorporating social cognitive performance, were run using FSL\'s PALM for each task, covarying for age and sex (1000 permutations, thresholded at p < 0.05 FWE-corrected). Exploratory region of interest (ROI)-based analyses were also conducted.
RESULTS: ImObs and EA analyses included 164 and 174 participants, respectively (autism N = 56/59, SSD N = 50/56, TDC N = 58/59). EA and both lower- and higher-level social cognition scores differed across groups. While canonical social cognitive networks were activated, no significant whole-brain or ROI-based group-level differences in neural correlates for either task were detected. Transdiagnostically, neural activity during the EA task, but not the ImObs task, was associated with lower- and higher-level social cognitive performance.
CONCLUSIONS: Despite attempting to match our groups on age, sex, and race, significant group differences remained. Power to detect regional brain differences is also influenced by sample size and multiple comparisons in whole-brain analyses. Our findings may not generalize to autism and SSD individuals with co-occurring intellectual disabilities.
CONCLUSIONS: The lack of whole-brain and ROI-based group-level differences identified and the dimensional EA brain-behavior relationship observed across our sample suggest that the EA task may be well-suited to target engagement in novel intervention testing. Our results also emphasize the potential utility of cross-condition approaches to better understand social cognition across autism and SSDs.

BACKGROUND: Headache is an illness with high prevalence and adverse effects on quality of life. As oral or dental problems such as pain can trigger or aggravate it, we aimed to investigate and compare oral and dental health status in patients affected with chronic headaches and healthy individuals.
METHODS: The present case-control study included 60 patients with chronic headaches (case) and 60 healthy individuals (control) in Rasht, Iran. The demographic characteristics and clinical examinations, including decayed/missing/filled teeth (DMF-T) and community periodontal index of treatment needs (CPITN) indices, as well as bruxism, frequency of tooth brushing and flossing, and maxillary and mandibular tooth wear were recorded in a checklist. Data analysis was performed using the IBM SPSS version 28 at a significance level of 0.05.
RESULTS: The case group consisted of 25 men (41.7%) and 35 women (58.3%) with an average age of 32.55 ± 6.62 years, while the control group had 27 men (45%) and 33 women (55%) with an average age of 30.95 ± 6.33 years. The study groups were not significantly different in bruxism, frequency of tooth brushing and flossing, DMFT, CPTIN, and maxillary and mandibular tooth wear.
CONCLUSIONS: It seems that chronic headaches do not significantly affect the oral and dental health of the sufferers. Moreover, it appears that these patients are well aware of the role of oral and dental hygiene in triggering or aggravating the episodes of headaches.

BACKGROUND: Accumulating evidence shows that free fatty acids (FFA) are associated with gestational diabetes mellitus (GDM). However, most of the studies focus on a few specific types of FFA, such as α-linolenic acid (C18:3n3) and Arachidonic acid (C20:4n6) or a total level of FFA.
OBJECTIVE: This study aimed to test the association between a variety of FFAs during the first trimester and the risk of GDM.
METHODS: The participants came from the Zhoushan Pregnant Women Cohort (ZWPC). A 1:2 nested case-control study was conducted: fifty mothers with GDM were matched with 100 mothers without GDM by age, pre-pregnancy body mass index (BMI), month of oral glucose tolerance test (OGTT) and parity. Thirty-seven FFAs (including 17 saturated fatty acids (SFA), 8 monounsaturated fatty acids (MUFA), 10 polyunsaturated fatty acids (PUFA) and 2 trans fatty acids (TFA)) in maternal plasma during the first trimester were tested by Gas Chromatography-Mass Spectrometry (GC-MS). Conditional logistic regression models were performed to assess the associations of FFA with the risk of GDM.
RESULTS: Nine FFAs were respectively associated with an increased risk of GDM (P < 0.05), and four FFAs were respectively associated with a decreased risk of GDM (P < 0.05). SFA risk score was associated with a greater risk of GDM (OR = 1.34, 95% CI: 1.12-1.60), as well as UFA risk score (OR = 1.26, 95% CI: 1.11-1.44), MUFA risk score (OR = 1.70, 95%CI: 1.27-2.26), PUFA risk score (OR = 1.32, 95%CI: 1.09-1.59) and TFA risk score (OR = 2.51, 95%CI: 1.23-5.13). Moreover, joint effects between different types of FFA risk scores on GDM were detected. For instance, compared with those with low risk scores of SFA and UFA, women with high risk scores of SFA and UFA had the highest risk of GDM (OR = 8.53, 95%CI: 2.41-30.24), while the Odds ratio in those with a low risk score of SFA and high risk score of UFA and those with a high risk score of SFA and low risk score of UFA was 6.37 (95%CI:1.33- 30.53) and 4.25 (95%CI: 0.97-18.70), respectively.
CONCLUSIONS: Maternal FFAs during the first trimester were positively associated with the risk of GDM. Additionally, there were joint effects between FFAs on GDM risk.
CONCLUSIONS: Elevated FFA levels in the first trimester increased the risk of GDM.
