Angiopoietin-like protein 4 induces growth hormone variant secretion and aggravates insulin resistance during pregnancy, linking obesity to gestational diabetes mellitus.

Angiopoietin-like protein 4 (ANGPTL4) is a secretory glycoprotein involved in regulating glucose homeostasis in non-pregnant subjects. However, its role in glucose metabolism during pregnancy and the pathophysiology of gestational diabetes mellitus (GDM) remains elusive. Thus, this study aimed to clarify the relationship between ANGPTL4 and GDM and investigate the pathophysiology of placental ANGPTL4 in glucose metabolism. We investigated this issue using blood and placenta samples in 957 pregnant women, the human 3A-sub-E trophoblast cell line, and the L6 skeletal muscle cell line. We found that ANGPTL4 expression in the placenta was higher in obese pregnant women than in lean controls. Palmitic acid significantly induced ANGPTL4 expression in trophoblast cells in a dose-response manner. ANGPTL4 overexpression in trophoblast cells resulted in endoplasmic reticulum (ER) stress, which stimulated the expression and secretion of growth hormone-variant (GH2) but not human placental lactogen. In L6 skeletal muscle cells, soluble ANGPTL4 suppressed insulin-mediated glucose uptake through the epidermal growth factor receptor (EGFR)/extracellular signal-regulated kinases 1/2 (ERK 1/2) pathways. In pregnant women, plasma ANGPTL4 concentrations in the first trimester predicted the incidence of GDM and were positively associated with BMI, plasma triglyceride, and plasma GH2 in the first trimester. However, they were negatively associated with insulin sensitivity index ISI0,120 in the second trimester. Overall, placental ANGPTL4 is induced by obesity and is involved in the pathophysiology of GDM via the induction of ER stress and GH2 secretion. Soluble ANGPTL4 can lead to insulin resistance in skeletal muscle cells and is an early biomarker for predicting GDM.

Clam Extract Decreases Nasal Symptoms and Improves Sleep Quality after Septoturbinoplasty.

Context: Nasal septal deviation (NSD) causes nasal blockage, which results in lower sleep quality among patients. A high percentage of patients still suffer from nasal symptoms as a result of the inflammatory response that occurs with septoturbinoplasty. Freshwater clams are a common food with an anti-inflammatory effect and have been used for promoting liver function for patients in China. Objectives: The study intended to evaluate the effects of clam extract (CE) in reducing inflammatory response, alleviating nasal blockage, and improving sleep quality for NSD patients after septoturbinoplasty. Design: The study was a randomized, controlled pilot that used a prospective design. Setting: The study took place at the Cheng Hsin General Hospital in Taipei, Taiwan. Participants: Participants were 52 patients with NSD at a clinic at the hospital. Intervention: Patients were randomly assigned to 2 groups: (1) an intervention group that received CE capsules and (2) a control group that received empty capsules that were identical in appearance to the CE capsules. Participants received the treatments 3 times a day for 2 weeks after septoturbinoplasty. Outcome Measures: Participants were assessed for nasal-symptom severity, wound inflammation, serum concentration of tumor necrosis factor alpha (TNF-α), and sleep quality. All outcome measures were undertaken at baseline, on various days during the study depending on the measure, and postintervention on day 14 for wound assessment and sleep quality. Results: After the septoturbinoplasty, the intervention group had lower nasal-symptom severity, wound inflammatory response, TNF-α concentration, and sleep disruption than those in the control group (P < .05). Conclusions: After septoturbinoplasty, CE can reduce nasal-symptom severity and inflammatory response and also improve patients' sleep quality. The anti-inflammatory effects of CE indicate that it can be considered to be an adjuvant therapy to improve sleep quality after surgery.

Serum vascular adhesion protein-1 is associated with twelve-year risk of incident cancer, cancer mortality, and all-cause mortality: a community-based cohort study.

Background: Vascular adhesion protein-1 (VAP-1), a dual-function glycoprotein, has been reported to play a crucial role in inflammation and tumor progression. We conducted a community-based cohort study to investigate whether serum VAP-1 could be a potential biomarker for predicting incident cancers and mortality. Method: From 2006 to 2018, we enrolled 889 cancer-free subjects at baseline. Serum VAP-1 levels were measured using a time-resolved immunofluorometric assay. Cancer and vital status of the participants were obtained by linking records with the computerized cancer registry and death certificates in Taiwan. Results: During a median follow-up of 11.94 years, 69 subjects developed incident cancers and 66 subjects died, including 29 subjects who died from malignancy. Subjects in the highest tertile of serum VAP-1 had a significantly higher risk of cancer incidence (p=0.0006), cancer mortality (p=0.0001), and all-cause mortality (p=0.0002) than subjects in the other tertiles. The adjusted hazard ratios per one standard deviation increase in serum VAP-1 concentrations were 1.28 for cancer incidence (95% CI=1.01-1.62), 1.60 for cancer mortality (95% CI=1.14-2.23), and 1.38 for all-cause mortality (95% CI=1.09-1.75). The predictive performance of serum VAP-1 was better than that of gender, smoking, body mass index, hypertension, diabetes, and estimated glomerular filtration rate but lower than that of age for cancer incidence, cancer mortality, and all-cause mortality, as evidenced by higher increments in concordance statistics and area under the receiver operating characteristic curve. Conclusion: Serum VAP-1 levels are associated with a 12-year risk of incident cancer, cancer mortality, and all-cause mortality in a general population.

Maternal Plasma Lipids During Pregnancy, Insulin-like Growth Factor-1, and Excess Fetal Growth.

CONTEXT: Maternal lipids during pregnancy and placental growth factors are associated with excess fetal growth. However, how these factors interact to increase the risk of delivering large-for-gestational-age (LGA) neonates remains unclear. In this study, we investigated the relationship between maternal plasma triglycerides (TGs) and free fatty acids (FFAs) during pregnancy, cord blood insulin-like growth factors (IGF), and LGA. OBJECTIVE: In a cell model, we studied the effect of different FAs on placental IGF-1 secretion. METHODS: This cohort study included pregnant women with term pregnancy and without diabetes or hypertensive disorders in pregnancy. Maternal fasting plasma TGs and FFAs were measured in the second trimester. Cord blood IGF-1, IGF-2, and IGF binding protein-1 and protein-3 were measured at the time of delivery. A human trophoblast cell line, 3A-sub-E, was used to evaluate the effect of different FFAs on placental IGF-1 secretion. RESULTS: We recruited 598 pregnant women-neonate pairs. Maternal plasma TG (180 mg/dL [152.5-185.5 mg/dL] vs 166 mg/dL [133-206 mg/dL], P = .04) and cord blood IGF-1 concentrations (72.7 ±â€…23.0 vs 54.1 ±â€…22.8 ng/mL, P < .001) were higher in the LGA group and were significantly associated with birth weight z score. Maternal plasma free palmitic acid (PA) and stearic acid (SA), but not oleic acid (OA) or linoleic acid (LA), were significantly associated with cord blood IGF-1 concentrations. In 3A-sub-E cells, treatment with PA, SA, and LA, but not OA, induced IGF-1 expression and secretion. CONCLUSION: Certain FFAs can induce placental IGF-1 secretion, which suggests a potential pathophysiology linking maternal plasma lipids and LGA.

Protective Effect of Calcitriol on Organ Damage Induced by 5-Fluorouracil Treatment.

Chemotherapy is a major therapeutic strategy for patients with cancer. Owing to the severe inflammatory response of chemotherapy, patients experience extreme discomfort during treatment, and this may interrupt treatment completion. The vitamin D3 has a role in anti-inflammation, but no study has explored whether vitamin D3 has beneficial effects on patients undergoing chemotherapy. In this study, we investigated the effect of calcitriol (Vit-D) on inflammatory responses during 5-fluorouracil (5-FU) treatment. Rats were divided into five groups and treated with 1:1 dilution of 5-FU with equal amount of 0.9% saline, 1:3 dilution of 5-FU with 0.9% saline threefold dilution, 5-FU, Vit-D, or 5-FU + Vit-D. A single dose of 15 mg/kg of 5-FU was intravenously administered for 4 h, and the blood biochemical substances and inflammatory cytokines were assessed after the intervention. The 5-FU group had higher AST, ALT, LDH, and CPK levels than those in the 5-FU + Vit-D group. The 5-FU + Vit-D group had a lower TNF-α value than the 5-FU. The IL-6 levels in the 5-FU + Vit-D group were also significantly lower than those in 5-FU. Calcitriol administration during 5-FU therapy can alleviate the production of inflammatory cytokines and liver damage.

Status of endocrinology and metabolism specialists in Taiwan.

BACKGROUND: The literature emphasizes the importance of matching the demand and supply of endocrinology and metabolism (EM) specialists. This study analyzed the current status of EM specialists in Taiwan. The gender effects on the workplace of EM specialists were also evaluated. METHODS: The number of internal medicine (IM) specialists was obtained from the websites of the Ministry of Health and Welfare. Data about EM specialists were retrieved from the database of the Endocrine Society of the Republic of China (ESROC; Taiwan). Differences in age distribution and workplace levels or locations between female and male EM specialists were analyzed. RESULTS: Since 1988, 809 physicians were certified as EM specialists. The average age of 739 EM specialists (509 male, 230 female) who remained as active members of the ESROC was 49.9 ± 11.1 years. The age distribution (p < 0.001) and workplace location (p = 0.043) were significantly different between male and female EM specialists. Divided by decades, the ratio of female-to-male EM specialists revealed an increasing tendency (p < 0.001). The percentage of EM specialists among IM specialists, certified 2 years previously, declined from 14.0% in 2017 to 7.9% and 8.3% in 2018 and 2019, respectively. CONCLUSION: The female-to-male ratio of EM specialists increased gradually. Compared to males, female EM specialists were relatively younger, and more of them had clinical practice in northern Taiwan. The percentage of IM specialists becoming EM specialists declined in the last 2 years. The equilibrium between the supply and demand of EM specialists deserves further investigation.

Progression of insulin resistance: A link between risk factors and the incidence of diabetes.

AIMS: Insulin resistance (IR) changes over time during the development of type 2 diabetes. Some reports showed that obesity was associated with progression of IR. However, no study has explored if change of IR predicts incident diabetes, and no study has investigated other factors associated with the change. METHODS: In this study, 1184 subjects without diabetes at baseline were enrolled in 2006-2016 with a median follow-up period of 4.5 years. Diabetes was diagnosed by oral glucose tolerance test and hemoglobin A1c, or if anti-diabetic agents were used. HOMA2-IR and ISI0,120 were used to estimate IR. RESULTS: The annual changes of HOMA2-IR(ΔHOMA2-IR/year) and ISI0,120(ΔISI0,120/year) were associated with BMI, waist circumference(WC), glucose, HbA1c, triglyceride and HDL-cholesterol. Subjects with pre-diabetes or metabolic syndrome were associated with a more rapid increase of IR. ΔHOMA2-IR/year and ΔISI0,120/year were correlated with annual changes of BMI and WC. The hazard ratios for ΔHOMA2-IR/year and ΔISI0,120/year to predict incident diabetes were 1.39 (95% CI 1.22-1.59, p < 0.001) and 0.13 (95% CI 0.09-0.19, p < 0.001) in adjusted models, respectively. CONCLUSIONS: Change of IR can be used as a surrogate marker of incident diabetes. The progression of IR is an important pathophysiologic link between risk factors and the incidence of diabetes.

Targeting fibrinogen-like protein 1 is a novel therapeutic strategy to combat obesity.

Fibrinogen-like-protein 1 (FGL1) is a novel hepatokine that plays an important role in hepatic steatosis and insulin resistance. Although FGL1 expression can be detected in adipose tissues, the functions of FGL1 in adipose tissues are still unknown. In this study, 356 participants with (body mass index (BMI) ≥25 kg/m2 ; n = 134) or without obesity (BMI <25 kg/m2 ; n = 222) were recruited, and we found that the plasma FGL1 concentrations were significantly higher in obese group than those of in the normal weight group, and were positively correlated with age, BMI, waist circumference, fat content, plasma glucose at 2 hours during an oral glucose tolerance test, and the insulin sensitivity index. In univariate analyses, BMI, waist circumference, total fat, visceral fat, and subcutaneous fat areas were positively correlated with FGL1 levels. After adjusting for age and gender, obesity indices, including the BMI and different fat areas, remained significantly associated with FGL1 levels. In order to investigate the causal relationship between FGL1 and obesity, animal and cell models were used. Overexpression of FGL1 in epididymal adipose tissue by lentiviral vector encoding FGL1 increased the fat pad size, whereas FGL1-knockdown by lentiviral vector encoding short-hairpin RNA targeted to FGL1 decreased high-fat diet-induced adiposity. In addition, 3T3-L1 adipocytes were used to clarify the possible mechanism of FGL1-induced adipogenesis. FGL1 induced adipogenesis through an ERK1/2-C/EBPß-dependent pathway in 3T3-L1 adipocytes. These findings highlight the pathophysiological role of FGL1 in obesity, and FGL1 might be a novel therapeutic target to combat obesity.

Overweight and obesity are associated with clustering of metabolic risk factors in early pregnancy and the risk of GDM.

AIM: Overweight and obesity are important risk factors of gestational diabetes mellitus (GDM). Clustering of metabolic risk factors in early pregnancy may be a potential pathogenesis between the link of overweight/obesity and GDM. Since it remains unexplored, we investigated if overweight and obesity are associated with clustering of metabolic risk factors in early pregnancy and the risk of GDM in this cohort study. METHODS: Total 527 women who visited National Taiwan University Hospital for prenatal care in between November 2013 to April 2018 were enrolled. Risk factors of GDM in the first prenatal visit (FPV) were recorded. Overweight/obesity was defined if body mass index ≥24 kg/m2. GDM was diagnosed from the result of a 75g oral glucose tolerance test in 24-28 gestational weeks. RESULTS: Overweight/obesity was associated with clustering of metabolic risk factors of GDM, including high fasting plasma glucose, high HbA1c, insulin resistance, high plasma triglyceride and elevated blood pressure in FPV (p<0.05). There was a positive relationship between the number of metabolic risk factors and the incidence of GDM (p <0.05). The odds ratios of HbA1c and diastolic blood pressure were higher in overweight/obese women, compared with those in normal-weight women. CONCLUSIONS: Overweight/obesity is associated with clustering of metabolic risk factors in early pregnancy, which is correlated with higher risk of GDM. Our findings suggest that metabolic risk factors during early pregnancy should be evaluated in overweight/obese women.

Long-term results of palatal implantation for severe obstructive sleep apnea patients with prominent retropalatal collapse.

BACKGROUND: Most previous reports on palatal implantation for patients with severe obstructive sleep apnea have been anecdotal. Our objective in this study was to assess the long-term outcomes of palatal implantations from objective as well as subjective perspectives when applied to patients with severe obstructive sleep apnea and prominent retropalatal collapse. METHODS: This retrospective review was conducted in a single institution using subjective data (Epworth Sleepiness Scale and visual analog scales of snoring sounds and sleep quality) and objective data (respiratory disturbance index, minimum O2 saturation, sleep efficiency, and snoring index using a polysomnograph) before and after surgery. A total of ten patients were enrolled in this study. The median time between pre-operative sleep-related tests and the operation date was 1.0 months and the median time between operation date and post-operative sleep-related tests was 33.0 months. RESULTS: Significant improvements were observed in the visual analog scale scores of snoring (p = 0.004), visual analog scale scores of sleep quality (p = 0.005), and Epworth Sleepiness Scale (p = 0.012). Eight of the ten patients reported a reduction of at least 50% on the visual analog scale of snoring sounds, which was the criterion of subjective surgical success. We also observed significant improvements in the respiratory disturbance index (p = 0.009) and minimum O2 saturation (p = 0.033). Two of the ten patients presented a reduction in respiratory disturbance index of ≥50% and a subsequent respiratory disturbance index of <20, which were the criteria of objective surgical success. A percentage change in respiratory disturbance index was negatively associated with prominent retrolingual collapse and the length of the soft palate. CONCLUSION: Patients with severe obstructive sleep apnea and prominent retropalatal collapse may benefit from palatal implantation from a subjective perspective. Palatal implantation could be considered an alternate form of treatment for some cases of severe obstructive sleep apnea, due to the likelihood of improvement in clinical symptoms and the normalization of sleep quality.

Screening gestational diabetes mellitus: The role of maternal age.

OBJECTIVE: Using a specific cutoff of fasting plasma glucose (FPG) to screen gestational diabetes mellitus (GDM) can reduce the use of oral glucose tolerance tests (OGTT). Since the prevalence of GDM increases with age, this screening method may not be appropriate in healthcare systems where women become pregnant at older ages. Therefore, we aimed to develop a screening algorithm for GDM that takes maternal age into consideration. METHODS: We included 945 pregnant women without history of GDM who received 75g OGTT to diagnose GDM in 2011. Screening algorithms using FPG with or without age were developed. Another 362 pregnant women were recruited in 2013-2015 as the validation cohort. RESULTS: Using FPG criteria alone, more GDM diagnoses were missed in women ≥35 years than in women <35 years (13.2% vs. 5.8%, p <0.001). Among GDM women ≥35 years, 63.6% had FPG <92 mg/dL (5.1 mmol/L). Use of the algorithm with an "age plus FPG" cutoff could reduce the use of OGTT (OGTT%) from 77.6% to 62.9%, while maintaining good sensitivity (from 91.9% to 90.2%) and specificity (from 100% to 100%). Similar reduction in OGTT% was found in the validation cohort (from 86.4% to 76.8%). In the simulation, if the percentage of women ≥35 years were 40% or more, the screening algorithm with an "age plus FPG" cutoff could further reduce OGTT% by 11.0%-18.8%. CONCLUSIONS: A screening algorithm for GDM that takes maternal age into consideration can reduce the use of OGTT when women become pregnant at older ages.

Adrenocorticotropic hormone levels before treatment predict recurrence of Cushing's disease.

BACKGROUND/PURPOSE: Cushing's disease (CD) is the most common cause of endogenous Cushing's syndrome. Transsphenoidal surgery (TSS) is the first choice of treatment. Predicting prognosis after treatment can benefit further strategies of management, but currently there is no convenient predictor. This study aims to investigate characteristic changes after treatment and to identify potential prognostic predictors. METHODS: We retrospectively studied the records of CD patients presenting to the National Taiwan University Hospital, Taipei, Taiwan between 1992 and 2011. They were categorized according to treatment response. Clinical features and examination findings were compared between groups. RESULTS: Forty-one patients with CD were included. The follow-up time was 0.26-19.3 years. The time interval between the onset of symptoms and diagnosis was 2.1-120.0 months. The initial remission rate of CD after the first treatment was 82.9%. Mean body mass index (BMI) was 27.4 kg/m2 before treatment and 26.0 kg/m2 3 months after treatment. The patients in remission had a greater decrease in BMI after treatment and lower dehydroepiandrosterone sulfate (DHEAS) levels before treatment, compared with the recurrent group (both p < 0.05). Adrenocorticotropic hormone (ACTH) levels before treatment showed a significant positive correlation with recurrent diseases (p < 0.05). CONCLUSION: A larger decrease in BMI after treatment and lower DHEAS levels before treatment were noted for the patients who stayed in CD remission. Higher ACTH levels before treatment predicted a recurrence of CD. These are potentially simple and practical predictors of prognosis.

MicroRNA-382-5p aggravates breast cancer progression by regulating the RERG/Ras/ERK signaling axis.

Aberrant activation of the Ras/ERK pathway mediates breast cancer initiation and aggressiveness. Therefore, it is important to identify miRNAs that modulate the Ras/ERK pathway during breast carcinogenesis and progression. The Ras GTPase superfamily member RERG (Ras-related and estrogen-regulated growth inhibitor) acts as a tumor suppressor to reduce breast cancer cell proliferation and tumor formation and has been suggested to have a regulatory role in the Ras/ERK pathway. In this study, we found that RERG exerted its tumor suppressor role by attenuating the activation of Ras/ERK signaling effectors. Furthermore, we found that miR-382-5p directly targets and represses RERG to attenuate the inhibitory effects of RERG on the oncogenic Ras/ERK pathway. Thereby, miR-382-5p promoted breast cancer cell viability, clonogenicity, survival, migration, invasion and in vivo tumorigenesis/metastasis. In clinical interpretation, miR-382-5p expression was negatively correlated with RERG expression, and it also significantly functioned as an independent oncomiR for the higher incidence and poorer prognosis of breast cancer. This novel connection highlights new diagnostic and prognostic roles for miR-382-5p and RERG in breast cancer.

Diagnosis of more gestational diabetes lead to better pregnancy outcomes: Comparing the International Association of the Diabetes and Pregnancy Study Group criteria, and the Carpenter and Coustan criteria.

AIMS/INTRODUCTION: The International Association of the Diabetes and Pregnancy Study Group (IADPSG) criteria for gestational diabetes are associated with increased prevalence. However, it remains unknown if intervention for more women with gestational diabetes mellitus by the IADPSG criteria results in better pregnancy outcomes than adopting the Carpenter and Coustan (C&C) criteria in Asian populations. MATERIALS AND METHODS: This was a retrospective cohort study. A total of 1,840 women, 952 subjects by the IADPSG criteria and 888 subjects by the C&C criteria, who delivered singletons in 2011 in a single tertiary center, were included in the study. The same therapeutic interventions were offered to women with gestational diabetes mellitus by the two criteria. Maternal and neonatal outcomes were evaluated. RESULTS: Adopting the IADPSG criteria increased the prevalence of gestational diabetes mellitus diagnosis to 13.44%, compared with 2.59% by the C&C criteria. The diagnosis was made 3 weeks earlier by the IADPSG criteria (27 vs 30.5 weeks, P < 0.0001). Adopting the IADPSG criteria was associated with reduced risk of primary cesarean section (adjusted odds ratio 0.79, 95% confidence interval 0.63-0.998, P < 0.05) and having any one of the adverse fetal outcomes (adjusted odds ratio 0.79, 95% confidence interval 0.64-0.998, P < 0.05), including birthweight >90th percentile, jaundice, admission to neonatal intensive care unit, birth trauma, neonatal hypoglycemia and fetal death. CONCLUSIONS: Adopting the IADPSG criteria is associated with improved pregnancy outcomes, at the expense of increased prevalence of gestational diabetes mellitus diagnosis.

Genetic determinants of antithyroid drug-induced agranulocytosis by human leukocyte antigen genotyping and genome-wide association study.

Graves' disease is the leading cause of hyperthyroidism affecting 1.0-1.6% of the population. Antithyroid drugs are the treatment cornerstone, but may cause life-threatening agranulocytosis. Here we conduct a two-stage association study on two separate subject sets (in total 42 agranulocytosis cases and 1,208 Graves' disease controls), using direct human leukocyte antigen genotyping and SNP-based genome-wide association study. We demonstrate HLA-B*38:02 (Armitage trend Pcombined=6.75 × 10(-32)) and HLA-DRB1*08:03 (Pcombined=1.83 × 10(-9)) as independent susceptibility loci. The genome-wide association study identifies the same signals. Estimated odds ratios for these two loci comparing effective allele carriers to non-carriers are 21.48 (95% confidence interval=11.13-41.48) and 6.13 (95% confidence interval=3.28-11.46), respectively. Carrying both HLA-B*38:02 and HLA-DRB1*08:03 increases odds ratio to 48.41 (Pcombined=3.32 × 10(-21), 95% confidence interval=21.66-108.22). Our results could be useful for antithyroid-induced agranulocytosis and potentially for agranulocytosis caused by other chemicals.

Deleterious effects of aggressive rapid crystalloid resuscitation on treatment of hyperinflammatory response and lung injury induced by hemorrhage in aging rats.

BACKGROUND: Large-volume, rapid crystalloid infusion may increase endothelial cell damage and induce shear stress, potentially leading to multiple-organ dysfunction syndrome. Limited guideline data for fluid administration are currently available, especially for the aging population. The aim of the present study was to compare the degree of organ damage in conscious aging rats when different resuscitation speeds were used during the treatment of hemorrhagic shock (HS). METHODS: Eighteen aging male Wistar-Kyoto rats were randomly divided into the following three groups: the control group, 30-min rapid resuscitation group, and 12-h slow resuscitation group. To mimic HS, 40% of the total blood volume was withdrawn. Fluid resuscitation (1:3) was given at 30 min after the blood withdrawal. Blood biochemical parameters including glucose, lactic acid, and lactate dehydrogenase (LDH) were measured along with the levels of serum and bronchoalveolar lavage fluid, tumor necrosis factor alpha (TNF-α), and interleukin 10 by enzyme-linked immunosorbent assay. The lungs were examined for pathologic changes, and the injury score at 24 h after HS was calculated. RESULTS: Compared with slow-rate resuscitation, initially rapid and immediate resuscitation significantly increased the serum levels of glucose, LDH, and proinflammatory cytokines (TNF-α and interleukin 10), and bronchoalveolar lavage fluid levels of white blood cells, TNF-α, and LDH as well as produced pathologic changes in the organ. The lung injury scores were higher after induced HS in aging rats. CONCLUSIONS: The slow and continuous (12 h) fluid resuscitation rate ameliorated HS-induced organ damage in conscious aging rats.

Dyslipidemia, kidney disease, and cardiovascular disease in diabetic patients.

This article reviews the relationship between dyslipidemia, chronic kidney disease, and cardiovascular diseases in patients with diabetes. Diabetes mellitus is associated with complications in the cardiovascular and renal system, and is increasing in prevalence worldwide. Modification of the multifactorial risk factors, in particular dyslipidemia, has been suggested to reduce the rates of diabetes-related complications. Dyslipidemia in diabetes is a condition that includes hypertriglyceridemia, low high-density lipoprotein levels, and increased small and dense low-density lipoprotein particles. This condition is associated with higher cardiovascular risk and mortality in diabetic patients. Current treatment guidelines focus on lowering the low-density lipoprotein cholesterol level; multiple trials have confirmed the cardiovascular benefits of treatment with statins. Chronic kidney disease also contributes to dyslipidemia, and dyslipidemia in turn is related to the occurrence and progression of diabetic nephropathy. Different patterns of dyslipidemia are associated with different stages of diabetic nephropathy. Some trials have shown that treatment with statins not only decreased the risk of cardiovascular events, but also delayed the progression of diabetic nephropathy. However, studies using statins as the sole treatment of hyperlipidemia in patients on dialysis have not shown benefits with respect to cardiovascular risk. Diabetic patients with nephropathy have a higher risk of cardiovascular events than those without nephropathy. The degree of albuminuria and the reduction in estimated glomerular filtration rate are also correlated with the risk of cardiovascular events. Treatment with angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers to reduce albuminuria in diabetic patients has been shown to decrease the risk of cardiovascular morbidity and mortality.
