Sleep and nighttime behavior disorders in older adults: associations with hypercholesterolemia and hypertriglyceridemia at baseline, and a predictive analysis of incident cases at 12 months follow-up.

INTRODUCTION: Sleep disorders, particularly insomnia and obstructive sleep apnea, are associated with dyslipidemia in the general population. The study's aim was to explore the association between pathological Cholesterol and Triglyceride levels, and sleep and nighttime behavior disorders (SNBD) in older adults, whether they might predict SNBD onset, and to emphasize the role of body mass index (BMI) in this association. METHODS: Alzheimer's Disease Neuroimaging Initiative (ADNI) population with complete Cholesterol, Triglyceride, SNBD, and neurocognitive data were included. Logistic regression was performed to study the association between hypercholesterolemia, hypertriglyceridemia, and SNBD at baseline and at 12 months. Relevant confounders, particularly BMI, were adjusted for. RESULTS: Among the 2,216 included cases, 1,045 (47%) were females, and the median age was 73 years (IQR: 68, 78). At baseline, 357 (16%) had SNBD and 327 (18%) at 12 months; 187 of them were incident cases. There were more cases of baseline SNBD in the hypertriglyceridemia group than in those without (19% vs. 14%, P-value = 0.003). Similarly, more follow-up SNBD cases had hypertriglyceridemia at baseline (21% vs. 16%, P-value = 0.025). SNBD cases at baseline had significantly higher serum Triglyceride levels than those without (132 vs. 118mg/dL, P-value < 0.001). Only hypertriglyceridemia was significantly associated with baseline SNBD (crude OR = 1.43, 95%CI: 1.13,1.80, P-value = 0.003), even after adjustment for confounding factors (adj. OR = 1.36, 95%CI: 1.06,1.74, P-value = 0.016) and (BMI-adj. OR = 1.29, 95%CI: 1.00,1.66, P-value = 0.048). None of the dyslipidemia forms did predict incident cases at 12 months. CONCLUSIONS: Hypertriglyceridemia, but not hypercholesterolemia, was associated with higher odds of SNBD. The association was independent of BMI. None of the dyslipidemia forms did predict incident SNBD over 12 months. Sleep disorders should motivate a systematic screening of dyslipidemia in older adults and vice versa.

Epidemiological aspects of the association of the hypertriglyceridemic waist phenotype with metabolic syndrome and cardiovascular risk factors in Morocco. Case the Amazigh population from a geographic region called Souss.

BACKGROUND: The global prevalence of metabolic syndrome (MetS) increases susceptibility to non-communicable diseases such as obesity, type 2 diabetes, and cardiovascular disease, posing significant health risks. Effective prevention and management require objective tools. The hypertriglyceridemic waist (TG+WC+) phenotype is proposed as a less expensive approach to identify individuals with metabolic syndrome and other cardiovascular risk factors. OBJECTIVE: The current aim of this investigation is to study the epidemiological characteristics of the hypertriglyceridemic waist phenotype and their correlations with cardiovascular risk factors and MetS in the Moroccan Amazigh ethnic group from the Souss region of Morocco. MATERIAL AND METHODS: A total of 827 Amazigh adults from the Sousse region of Morocco were divided into four distinct phenotype groups: TG-WC-, TG+WC-, TG-WC+, and TG+WC+ (normal TG- or high TG+ triglycerides/normal WC- or high WC+ waist circumference). The association of the different phenotypes with MetS and other cardiovascular risk factors was established by logistic regression analysis. RESULTS: The prevalence of the TG+WC+ phenotype was 27.7% and varied according to age group and sex. Among subjects with the TG+WC+ phenotype, most were 41-60 years old (53.3%) and in women (74.2%). Participants with the TG+WC+ phenotype had the highest prevalence of dyslipidemia (87.3%), hypoHDLaemia (69.9%), and general obesity (37.12%). The three phenotypes TG-WC-, TG+WC- and TG-WC+ were less associated with MetS and other cardiovascular risk factors. Moreover, people with the TG+WC+ phenotype had a very high odds ratio for MetS. CONCLUSION: These findings suggest that the TG+WC+ phenotype exhibits a robust correlation with MetS and additional variables connected to cardiovascular risk. The TG+WC+ phenotype serves as a valuable clinical instrument for detecting individuals vulnerable to MetS and cardiovascular diseases.

Fasting hypertriglyceridemia in relation to mortality in an elderly male Chinese population.

We investigated fasting hypertriglyceridemia as predictors of all-cause, cardiovascular, and non-cardiovascular mortality in an elderly male Chinese population, while accounting for various conventional cardiovascular risk factors. Our participants were elderly men recruited from residents living in a suburban town of Shanghai (≥60 years of age, n = 1583). Hypertriglyceridemia was defined as a fasting serum triglycerides concentration ≥1.70 mmol/L. Subgroup analyses were performed according to current smoking (yes vs. no), alcohol intake (yes vs. no), and the presence and absence of hypertension and hyperglycemia. During a median of 7.9 years follow-up, all-cause, cardiovascular, and non-cardiovascular deaths occurred in 279, 112, and 167 participants, respectively. After adjustment for confounding factors, fasting hypertriglyceridemia was not significantly (p ≥ .33) associated with the risk of all-cause, cardiovascular, and non-cardiovascular mortality. However, there was significant (p = .03) interaction between hypertriglyceridemia and the presence and absence of hypertension in relation to all-cause mortality. In normotensive, but not hypertensive individuals, hypertriglyceridemia was significantly associated with a higher risk of all-cause mortality (hazard ratio 1.57, 95% confidence interval 1.06-2.31). In further non-parametric analyses in normotensive individuals, the age-standardized rate for all-cause mortality increased from 18.9 in quartile 1 to 20.0, to 24.7, and to 39.9 per 1000 person-years in quartiles 2, 3, and 4 of serum triglycerides concentration, respectively (ptrend = .0004). Similar results were observed for cardiovascular mortality. Our study in elderly male Chinese showed that fasting hypertriglyceridemia was associated with a higher risk of all-cause and cardiovascular mortality in patients with normotension but not those with hypertension.

A cohort analysis of familial partial lipodystrophy from two Mediterranean countries.

AIM: To assess the disease burden of familial partial lipodystrophy (FPLD) caused by LMNA (FPLD2) and PPARG (FPLD3) variants to augment the knowledge of these rare disorders characterized by selective fat loss and metabolic complications. MATERIALS AND METHODS: An observational longitudinal study, including 157 patients (FPLD2: 139 patients, mean age 46 ± 17 years, 70% women; FPLD3: 18 patients, mean age: 44 ± 17 years, 78% women) from 66 independent families in two countries (83 from Turkey and 74 from Spain), was conducted. RESULTS: Patients were diagnosed at a mean age of 39 ± 19 years, 20 ± 16 years after the first clinical signs appeared. Men reported symptoms later than women. Symptom onset was earlier in FPLD2. Fat loss was less prominent in FPLD3. In total, 92 subjects (59%) had diabetes (age at diagnosis: 34 ± 1 years). Retinopathy was more commonly detected in FPLD3 (P < .05). Severe hypertriglyceridaemia was more frequent among patients with FPLD3 (44% vs. 17%, P = .01). Hepatic steatosis was detected in 100 subjects (66%) (age at diagnosis: 36 ± 2 years). Coronary artery disease developed in 26 patients (17%) and 17 (11%) suffered from a myocardial infarction. Turkish patients had a lower body mass index, a higher prevalence of hepatic steatosis, greater triglyceride levels and a tendency towards a higher prevalence of coronary artery disease. A total of 17 patients died, with a mean time to death of 75 ± 3 years, which was shorter in the Turkish cohort (68 ± 2 vs. 83 ± 4 years, P = .01). Cardiovascular events were a major cause of death. CONCLUSIONS: Our analysis highlights severe organ complications in patients with FPLD, showing differences between genotypes and Mediterranean countries. FPLD3 presents a milder phenotype than FPLD2, but with comparable or even greater severity of metabolic disturbances.

Cardiovascular Risk Factors as Predictors of Nutritional Status in Older Mexican Adults.

Aging is commonly accompanied by increased cardiovascular risk and diet plays a crucial role in health condition. The aim of this study was to determine cardiovascular risk factors as predictors of nutritional risk in Mexican older adults. A cross-sectional study on Mexican patients aged ≥60 years with cardiovascular risk factors affiliated with a medical unit in Northeast Mexico was performed from July to December 2021. The nutritional risk evaluations were performed using the Mini Nutritional Assessment (MNA) questionnaire. After a multivariate analysis, the cardiovascular risk factors identified as independent predictors of risk of malnutrition were hypertriglyceridemia (adjusted OR (AOR): 1.8; 95% CI: 1.03-3.14; p = 0.04) and systolic hypertension I (AOR: 2.28; 95% CI: 1.04-5.02; p = 0.041); age over 80 years (AOR: 5.17; 95% CI: 1.83-14.65, p = 0.002) and elementary school education (AOR: 2.34; 95% CI: 1.20-4.55; p = 0.013) were also related. The cross-sectional design and single-center approach of this study limits the generalizability of the results; however, conducting timely evaluations of blood pressure, triglyceride levels, and risk of malnutrition using the MNA tool for patients aged ≥60 years could prevent illness and reduce mortality within this population group.

Unraveling the link between hypertriglyceridemia, dampness syndrome, and chronic diseases: A comprehensive observational study.

To investigate the dampness syndrome score in hypertriglyceridemia and the correlations between hypertriglyceridemia and other chronic diseases and lifestyle factors. Data were retrospectively obtained from individuals who underwent physical examinations at Guangzhou Cadres Health Management Centre from May 2022 to May 2023. t Test, variance analysis, and chi-square test were used to compare the score of dampness syndrome and the prevalence of hypertriglyceridemia among different subgroups. Pearson, Spearman correlation analysis, and regression analysis were used to explore the correlations between hypertriglyceridemia and dampness syndrome, chronic diseases, and lifestyle factors. The prevalence of hypertriglyceridemia was 26.70%. Clinical test index and dampness syndrome score were significant differences between hypertriglyceridemia group and normal group (P < .05). Subgroup analyses as a function of the degree of triglyceridemia indicated that the dampness syndrome score increased with increasing degree of triglyceridemia (P < .05). Correlation analysis showed that hypertriglyceridemia was correlated with dampness syndrome, overweight/obesity, hypertension, diabetes, and other chronic diseases (P < .05). Multivariate logistic regression analysis showed that age, sex, marriage, education level, smoking, drinking, fruit consumption, vegetable consumption, milk and dairy product consumption, dessert or snack consumption, the degree of dampness syndrome, and engagement in exercise were associated with hypertriglyceridemia (P < .05). Hypertriglyceridemia is associated with a variety of chronic diseases and lifestyle factors, and is closely related to dampness syndrome. The score of dampness syndrome can reflect hypertriglyceridemia to a certain extent. It provides more clinical reference for the treatment of hypertriglyceridemia combined with the analysis of dampness syndrome of traditional Chinese medicine.

Impact of Korean Military Service on the Prevalence of Steatotic Liver Disease: A Longitudinal Study of Pre-enlistment and In-Service Health Check-Ups.

Background/Aims: Young Korean men are obligated to serve in the military for 18 to 21 months. We investigated the effects of military service on steatotic liver disease (SLD) and other metabolic parameters. Methods: Pre-enlistment health check-up performed from 2019 to 2022 and in-service health check-up performed from 2020 to 2022 were merged as paired data. SLD was defined as a hepatic steatosis index of 36 or higher. Hypertension (HTN) and hypertriglyceridemia were also included in the analysis. Results: A total of 503,136 paired cases were included in the analysis. Comparing pre-enlistment and in-service health check-ups, the prevalence of SLD (22.2% vs 17.6%, p<0.001), HTN (7.6% vs 4.3%, p<0.001), and hypertriglyceridemia (8.1% vs 2.9%, p<0.001) decreased during military service. In terms of body mass index, the proportion of underweight (8.2% vs 1.4%, p<0.001) and severely obese (6.1% vs 4.9%, p<0.001) individuals decreased over time. Regarding factors associated with SLD development and resolution, age was positively associated with SLD development (odds ratio, 1.146; p<0.001) and a health check-up interval of <450 days was a protective factor for SLD development (odds ratio, 0.746; p<0.001). Those serving in the marines were less likely to develop SLD, whereas those serving in the navy were more likely to develop SLD. Serving in the army or the navy was negatively associated with SLD resolution, whereas serving in the air force was positively associated with SLD resolution. Conclusions: The prevalence of SLD, HTN, and hypertriglyceridemia decreased substantially during Korean military service.

Hypertriglyceridemia, Hypercholesterolemia, Body Mass Index, and the Risk of Acute Pancreatitis.

OBJECTIVE: The purpose of this work was to check the connection between parameters of lipid profile and body mass index (BMI) in relation to the occurrence of acute pancreatitis within a sample of adults from northern China. METHODOLOGY: A total of 123,214 participants from the Kailuan Group were incorporated into this prospective study. The subjects were categorized into quartiles on the basis of their initial levels of triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). On the basis of BMI classification, the individuals in the study were divided into three distinct groups: normal weight, overweight, and obese. The data were analyzed to explore the correlation between lipid profile and BMI with acute pancreatitis. RESULTS: Over a period of 12.59 ± 0.98 years, during the median follow-up duration, a total of 410 new patients with acute pancreatitis were recorded. The occurrence rate and total occurrence of acute pancreatitis demonstrated an upward trend in correlation with elevated levels of TG, TC, and BMI. Following adjustment for multiple variables, it was observed that individuals in the fourth quartile of TG and TC levels demonstrated the highest likelihood of developing acute pancreatitis. Furthermore, our analysis revealed that a proportion of 19.29% of the correlation between BMI and the likelihood of experiencing acute pancreatitis can be attributed to the influence of elevated TG levels, whereas 12.69% of the association was mediated by higher TC. CONCLUSIONS: We found that hypertriglyceridemia, hypercholesterolemia, and obesity were risk factors for acute pancreatitis, especially in young and middle-aged men.TG and TC were the mediating factors between BMI and the risk of acute pancreatitis.

Anthropometry for predicting cardiometabolic disease risk factors in adolescents.

OBJECTIVE: Early screening prevents chronic diseases by identifying at-risk adolescents through anthropometric measurements, but predictive value in diverse groups is uncertain. METHODS: A cross-sectional analysis of 12- to 19-year-old individuals from the 2017-2018 National Health and Nutrition Examination Survey (NHANES) assessed the predictive ability of BMI percentile, total body fat percentage, waist circumference (WC), and waist-hip ratio (WHR) for four cardiometabolic risk factors across race and ethnicity groups using receiver operating characteristic curves. RESULTS: The unweighted sample (N = 1194; 51.2% male individuals; 23.7% Hispanic, 13.2% non-Hispanic Black [NHB], 51.1% non-Hispanic White [NHW], 12.0% other/multirace) had a weighted prevalence of elevated blood pressure of 2.7%, hyperglycemia of 36.8%, hypertriglyceridemia of 4.8%, and low high-density lipoprotein (HDL) cholesterol of 15%. WHR (area under the curve [AUC] = 0.77), WC (AUC = 0.77), and BMI percentile (AUC = 0.73) outperformed total body fat percentage (AUC = 0.56) in predicting elevated blood pressure (p < 0.001 for all). BMI percentile was more accurate than total body fat percentage in predicting hypertriglyceridemia (AUC = 0.70 vs. 0.59; p = 0.02) and low HDL cholesterol (AUC = 0.69 vs. 0.59; p < 0.001). Race and ethnicity-based predictions varied: NHW adolescents had the highest AUC (0.89; p < 0.01) for elevated blood pressure prediction compared with Hispanic and NHB adolescents (AUC = 0.77 for both). Total body fat percentage was more accurate in predicting low HDL cholesterol among Hispanic versus NHW adolescents (AUC = 0.73 vs. 0.58; p = 0.04). CONCLUSIONS: WHR, WC, and BMI percentile are better predictors of cardiometabolic risk factors in adolescents than total body fat percentage. Predictive abilities differed by race and ethnicity, highlighting the importance of tailored risk assessment strategies.

Association of serum uric acid with hypertriglyceridemia in children and adolescents: a cross-sectional study.

BACKGROUND: Uric acid (UA), a liver-derived metabolite, is intimately tied to metabolic disorders. Although ample research underscores its connection with hypertriglyceridemia (HTG), studies focusing on adolescents remain limited. To fill the gaps in epidemiology,this study focused on analyzing the relationship between the levels of uric acid and HTG in a demographic sample comprising adolescents from the United States. METHODS: In this study, a total of 4,435 participants through the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2020. The exposure variable was serum uric acid (SUA), the effect variable was HTG, and the covariates included demographic, questionnaire, physical examination and laboratory indicators. We utilized weighted logistic regression and meticulous subgroup evaluations to discern the intrinsic link between SUA and HTG. Stratified analyses augmented the validation of this association, while smooth curve fitting probed for potential nonlinear correlations. RESULTS: The study included 4,435 participants. Male adolescents exhibit elevated SUA levels. After adjusting for all variables, the weighted multiple logistic regression model revealed that SUA was positively correlated with HTG risk (OR = 1.006, 95% CI: 1.005-1.007). This relationship was consistent across the three tertiles group of SUA (T1: OR = 1.006 [95% CI: 1.005-1.007]; T2: OR = 1.006 [95% CI: 1.005-1.007]; T3: OR = 1.004 [95% CI: 1.003-1.006]; P for trend < 0.001). Stratified analyses confirmed that the positive correlation between SUA and HTG risk was significant, irrespective of sex, age or race. CONCLUSIONS: In American children and adolescents aged 12 to 18 years, there was a pronounced association between SUA and HTG. SUA could serve as a risk indicator for HTG. It is recommended that children diagnosed with HTG should be regularly tested for SUA levels. In addition, it is recommended that SUA be included in the comprehensive care of children diagnosed with HTG.

Association of admission serum triglyceride levels with intensive care unit hospitalization rates in acute pancreatitis patients: A retrospective study.

Acute pancreatitis (AP) is a complex and unpredictable condition, of which hypertriglyceridemia (HTG) is the third most prevalent cause. This study aimed to conduct a retrospective analysis of clinical data from hospitalized AP patients to uncover a potential correlation between triglyceride (TG) levels and the necessity for intensive care unit (ICU) admission. This retrospective cohort study utilized the Medical Information Mart for Intensive Care IV 2.2 (MIMIC-IV) critical care dataset, incorporating data from 698 patients with hypertriglyceridemic acute pancreatitis (HTG-AP). The analysis employed the RCS model along with univariate and multivariate logistic regression methods to affirm the association between triglyceride levels and ICU admission. Subgroup analysis was performed to investigate specific populations. The study included 698 patients with AP, 42.41% of whom experienced HTG during hospitalization. RCS analysis revealed a linear association between TG levels and risk of ICU admission (p for nonlinear = .219, p for overall = .009). Multivariate logistic regression analysis indicated an increased risk of ICU admission in the TG range of 1.7-5.65 mmol/L (aOR = 1.83, 95% CI 1.12-2.99, P = .015) and TG >11.3 mmol/L (aOR = 5.69, 95% CI 2.36-13.74, P < .001) compared to the normal group. Similar results were observed across the various subgroups. As triglyceride levels increased, there was a corresponding increase in ICU admissions. Patients within the 1.7 to 5.65 mmol/L and > 11.3 mmol/L triglyceride groups exhibited higher rates of ICU admissions. Moreover, we observed a higher risk of ICU hospitalization even with mild TG elevation.

Glycemic Index, Glycemic Load and Dyslipidemia in Adolescents from Chiapas, Mexico.

Cardiovascular disease risk throughout the life course is increased by abnormal blood lipid levels in youth. The dietary glycemic index (GI) and glycemic load (GL) during adolescence might be related to abnormal blood lipids. This study aimed to analyze the association between dietary GI, GL and dyslipidemia in adolescents from two marginalized regions of Chiapas, Mexico. A cross-sectional study was conducted with 213 adolescents. Food intake was assessed using 24 h recalls. The association between dyslipidemia and dietary GI or GL was tested by using logistic regression models. Low HDL-c was the most prevalent risk factor (47.4%), followed by hypertriglyceridemia (25.4%). In this population, overall dietary GI was not associated with dyslipidemia. A high dietary GL was associated with 2.39 higher odds of low HDL-c (95% CI: 1.21-4.74) when compared to low GL. Female adolescents with high dietary GL had 3.20 higher odds of hypertriglyceridemia (95% CI: 1.03-9.88), whereas no association was found for males. No associations were observed between overall dietary GL and total cholesterol or LDL-c. In adolescents from urban and rural communities in Chiapas, a high dietary GL was associated with a detrimental effect on HDL-c. In female adolescents, high GL was associated with hypertriglyceridemia.

Recurrence of hypertriglyceridemia-associated acute pancreatitis: A multicenter, prospective cohort study.

OBJECTIVES: There are scarce prospective data on recurrent hypertriglyceridemia-associated acute pancreatitis (HTG-AP). This study aimed to investigate the incidence, potential prognostic factors, and clinical relevance of recurrent HTG-AP. METHODS: This study is a multicenter, prospective cohort study. Adult patients with the first HTG-AP attack enrolled in the PERFORM registry between November 2020 and December 2021 were involved. All the study patients were followed up for more than two years with a two-round schedule. The Cox proportional-hazards model was applied to analyze the potential factors. Quality of life was evaluated using the EuroQol five-dimensional five-level health scale (EQ-5D-5L). RESULTS: A total of 184 patients from 25 sites were included in the study, and 161 patients completed the two-round follow-up. Among them, the mean follow-up time for the study patients was 31±4 months, and the incidence rate of recurrent HTG-AP attack was 23 % (37/161). All patients with recurrent episodes required readmission to the hospital. The EQ visual analog scale (VAS) score was significantly lower in patients with recurrent episodes compared to those without (76±10 vs. 82±12; P = 0.02) at the latest follow-up. Age <40 years old (hazard ratio [HR], 3.6; 95 % confidence interval [CI], 1.5-8.7; P = 0.004) and a history of diabetes (HR, 2.6; 95 %CI, 1.3-5.1; P = 0.005) were identified as potential predictor factors for recurrence. CONCLUSIONS: Recurrence of HTG-AP is common, especially for younger patients with diabetes. Recurrence necessitated additional hospital readmissions and was associated with compromised quality of life.

Incidence of non-AIDS defining comorbidities among young adults with perinatally acquired HIV in North America.

OBJECTIVE: The aim of this study is to describe the incidence of diabetes mellitus type 2 (T2DM), hypercholesterolemia, hypertriglyceridemia, hypertension, and chronic kidney disease (CKD) from 2000 to 2019 among North American adults with perinatally acquired HIV (PHIV) aged 18-30 years. DESIGN: Description of outcomes based on electronic health records for a cohort of 375 young adults with PHIV enrolled in routine HIV care at clinics contributing data to the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD). METHODS: We estimated overall, sex, and race-stratified cumulative incidences using Turnbull estimation, and incidence rates using quasi-Poisson regression. T2DM was defined as glycosylated hemoglobin more than 6.5% or based on clinical diagnosis and medication use. Hypercholesterolemia was based on medication use or total cholesterol at least 200 mg/dl. Hypertriglyceridemia was based on medication use or fasting triglyceride at least 150 mg/dl or nonfasting at least 200 mg/dl. Hypertension was based on clinical diagnosis. CKD was defined as estimated glomerular filtration rates less than 90 ml/mi|1.73 m 2 for at least 3 months. RESULTS: Cumulative incidence by age 30 and incidence rates from age 18 to 30 (per 100 person-years) were T2DM: 19%, 2.9; hypercholesterolemia: 40%, 4.6; hypertriglyceridemia: 50%, 5.6; hypertension: 22%, 2.0; and CKD: 25%, 3.3. Non-Black women had the highest incidence of hypercholesterolemia and hypertriglyceridemia, Black adults had the highest hypertension incidence, and Black men had the highest CKD incidence. CONCLUSION: There was a high incidence of five chronic comorbidities among people with PHIV. Earlier screening at younger ages might be considered for this unique population to strengthen prevention strategies and initiate treatment in a timely way.

Clinical characteristics and pregnancy outcome analysis of 20 cases of acute pancreatitis during pregnancy.

OBJECTIVE: This study investigated the clinical characteristics and pregnancy outcomes of acute pancreatitis during pregnancy (APIP). METHODS: A retrospective analysis was conducted on 20 cases of APIP admitted to Hubei Maternal and Child Health Hospital from January 2017 to September 2021. The etiology, clinical manifestations, and perinatal outcomes of APIP were analyzed using descriptive statistical analysis of the collected data. RESULTS: The incidence of APIP in our hospital was 20 (0.02%) cases, all of which occurred in the late stage of pregnancy. Hypertriglyceridemic acute pancreatitis (HTG-AP) was the primary cause of APIP in 10 (50.0%) patients. A total of 11 (55.0%), seven (35.0%) and two (10.0%) patients had mild acute pancreatitis (MAP), moderately severe acute pancreatitis (MSAP) and severe acute pancreatitis (SAP), respectively. Pregnant women with HTG-AP had significantly elevated serum triglyceride levels, had higher prepregnancy body mass indices, were more prone to developing diabetes and were more likely to progress to SAP. With a multidisciplinary approach and individualized treatment plans, there were no maternal deaths, and fetal death only occurred in one (5.0%) case. CONCLUSION: HTG-AP is prone to advancing to more severe states, and it is becoming more common every year. Therefore, blood lipid management during pregnancy should be emphasized. Pregnant women with digestive symptoms or severe hyperlipidaemia should be screened for APIP in a timely manner and receive clinical intervention to improve maternal and fetal outcomes during the perinatal period.

Elevated plasma triglycerides increase the risk of psoriasis: a cohort and Mendelian randomization study.

BACKGROUND: It is increasingly clear that triglyceride-rich lipoproteins are proinflammatory and cause low-grade systemic inflammation. However, it is currently unknown whether elevated plasma triglycerides are causally related to the development of psoriasis, a skin disorder driven by chronic inflammation. OBJECTIVES: To determine if elevated plasma triglycerides are associated with increased risk of psoriasis in observational and Mendelian randomization analysis. METHODS: Consecutive individuals from the Copenhagen General Population Study were included. We used plasma triglycerides (n = 108 043) and a weighted triglyceride allele score (n = 92 579) on nine known triglyceride-altering genetic variants. Genetic results were replicated in 337 159 individuals from the UK Biobank. Psoriasis was defined using the International Classification of Diseases, version 10 (ICD-10) code for hospital contact in the main analyses, and prescription of topical antipsoriatics for mild psoriasis in the sensitivity analysis. RESULTS: During a follow-up of median (range) 9.3 (0.1-15.1) years from 2003 to 2015 through 2018, 855 (1%) individuals were diagnosed with psoriasis by ICD-10 in the observational analysis and 772 (1%) in the Mendelian randomization analysis. In the observational analysis, the multivariable adjusted hazard ratio for psoriasis by ICD-10 was 1.26 [95% confidence interval (CI) 1.15-1.39] per doubling in plasma triglycerides with a corresponding causal odds ratio of incident psoriasis of 2.10 (95% CI 1.30-3.38). Causality was confirmed from data from the UK Biobank. Results were similar but slightly attenuated when we used topical antipsoriatic prescriptions for mild psoriasis. CONCLUSIONS: Elevated plasma triglycerides are associated with an increased risk of psoriasis in observational and Mendelian randomization analysis.

Psoriasis is a common skin condition, characterized by inflammation in the body (the body's response to an unwanted agent). People with psoriasis often have higher lipid levels in their blood compared with people without psoriasis. Some studies have shown that triglyceride-rich lipoprotein (a certain type of lipid) is irritative to the body and can cause inflammation. However, it is unclear whether high levels of triglycerides in the blood can cause them to penetrate into the skin and trigger the onset of psoriasis. We aimed to test this question in 100,000 people from a Danish population without previously diagnosed psoriasis. Specifically, we measured plasma triglycerides at initial examination and at the same time assessed the same people for genetic variants that impact on the concentration of plasma triglycerides. Importantly, genetic variants are inherited by chance, meaning that we could look specifically at whether a change in triglycerides was the mechanism that causes psoriasis. Next, we observed these people for about 10 years and noted any new occurrence of psoriasis during follow-up. We found that the risk of developing psoriasis was higher both as a function of plasma triglyceride concentration and the genetic variants that increase plasma triglyceride concentration. Overall, our study findings suggest that high levels of triglycerides in the blood could be a causal risk factor for the development of psoriasis.

Cumulative exposure to hypertriglyceridemia and risk of type 2 diabetes in young adults.

AIM: This study aimed to examine whether cumulative exposure to hypertriglyceridemia is associated with an increased risk of developing type 2 diabetes in young adults. METHODS: The study included 1,840,251 participants aged 20-39 years who had undergonefourconsecutiveannualhealth checkups and had no history of type 2 diabetes. Participants werecategorized into five groups (exposure score 0-4) based on the frequencies of hypertriglyceridemia diagnosis over a four-year period. The primary outcome was newly diagnosed type 2 diabetes. Exploratory analyses were performed for the different subgroups. RESULTS: During a follow-up period of 6.53 years, 40,286 participants developed type 2 diabetes. The cumulative incidence of type 2 diabetes significantly increased with higher exposure scores for hypertriglyceridemia (log-rank test, P < 0.001). The multivariable-adjusted hazard ratios for incident diabetes were 1.674 (95 % CI, 1.619, 1.732), 2.192 (95 % CI, 2.117, 2.269), 2.637 (95 % CI, 2.548, 2.73), and 3.715 (95 % CI, 3.6, 3.834) for participants with scores of 1-4, respectively, compared with those with an exposure score of 0. CONCLUSIONS: In this large-scale prospective cohort study of young adults, cumulative exposure to hypertriglyceridemia was significantly associated with an increased risk of type 2 diabetes, independent of lifestyle-related factors.

Comparison of Sampson and extended Martin/Hopkins methods of low-density lipoprotein cholesterol calculations with direct measurement in pediatric patients with hypertriglyceridemia.

OBJECTIVE: The Friedewald equation is the commonly used method of low-density lipoprotein cholesterol (LDL-C) calculation, requiring reflex to direct LDL-C measurement when triglycerides (TG) ≥ 400 mg/dL. Recently formulated Sampson and extended Martin/Hopkins methods have been validated with TG up to 800 mg/dL and thus have the potential to replace direct LDL-C measurement. Given the growing prevalence of childhood dyslipidemia, the objective of this study was to compare Sampson and extended Martin/Hopkins methods of LDL-C calculation with the direct measurement in a pediatric cohort with 400 ≤ TG ≤ 799 mg/dL. METHODS: This study retrieved standard lipid panels and corresponding direct LDL-C measurements of 131 patients with 400 ≤ TG ≤ 799 mg/dL from a pediatric population. Following the application of Sampson and extended Martin/Hopkins calculations, calculated values were compared with direct LDL-C measurements using ordinary least squares linear regression analysis and bias plotting. RESULTS: Both Sampson and extended Martin/Hopkins LDL-C calculations exhibited a strong correlation with the direct measurements (Pearson r = 0.89) in patients with 400 ≤ TG ≤ 800 mg/dL. Average percentages of bias of 45% and 21% were found between the direct LDL-C measurements and Sampson or extended Martin/Hopkins calculations, respectively. CONCLUSION: Both Sampson and extended Martin/Hopkins calculations are applicable as clinical alternatives of direct LDL-C measurement in pediatric patients given 400 ≤ TG ≤ 799 mg/dL.

Postprandial triglycerides across the aging spectrum: A secondary analysis utilizing an abbreviated fat tolerance test.

BACKGROUND & AIMS: Elevated postprandial triglycerides are an independent cardiovascular disease risk factor and observed in older adults. However, differences in postprandial triglycerides across the spectrum of adulthood remain unclear. METHODS AND RESULTS: We performed a secondary analysis of six studies where adults (aged 18-84 years; N = 155) completed an abbreviated fat tolerance test (9 kcal/kg; 70% fat). Differences in postprandial triglycerides were compared in those ≥50 and <50 years and by decade of life, adjusting for sex and BMI. Compared to those <50 years, participants ≥50 years had higher fasting, 4 h, and Δ triglycerides from baseline (p's < 0.05). When examining triglyceride parameters by decade, no differences were observed for fasting triglycerides, but 50 s, 60 s, and 70s-80 s displayed greater 4 h and Δ triglycerides versus 20 s (p's ≤ 0.001). The frequency of adverse postprandial triglyceride responses (i.e., ≥220 mg/dL) was higher in participants ≥50 versus <50 years (p < 0.01), and in 60 s compared to all other decades (p = 0.01). CONCLUSION: Older age was generally associated with higher postprandial triglycerides, with no divergence across the spectrum of older adulthood. In our sample, postprandial triglyceride differences in older and younger adults were driven by those >50 years relative to young adults in their 20 s. REGISTRATION: N/A (secondary analysis).
