Prevalence, trend, and associated risk factors for cleft lip with/without cleft palate: a national study on live births from 2016 to 2021

BackgroundsCleft lip with or without cleft palate (CL/P) is the most common congenital craniofacial anomaly, including non-syndromic cleft lip with or without cleft palate and cleft palate only. Failure in the fusion of median and lateral nasal processes, the maxillary prominence, and soft tissues around the oral cavity can cause CL/P. Previously, the prevalence has been estimated to be 1 among every 1000 births in 2014 among American neonates and no other reports have been available since. Thus, this study aimed to calculate the prevalence and trend of isolated CL/P among American live births from 2016 to 2021 with its associated risk factors.Methods and materialsIn this cross-sectional population-based retrospective study, we used live birth data provided by the National Center for Health Statistics (NCHS) from the Center for Disease Control and Prevention (CDC). We calculated the prevalence per 10,000 live births of isolated (non-syndromic) CL/P from 2016 to 2021. To examine risk factors for developing isolated CL/P, we used logistic regression modelling.ResultsThe total prevalence per 10,000 births from 2016 to 2021 was 4.88 (4.79–4.97), for both sexes, and 5.96 (5.82–6.10) for males, and 3.75 (3.64–3.87) for females. The prevalence did not show any consistent linear decreasing or increasing pattern. We found significant association between increased odds of developing isolated CL/P among cases with 20 to 24 year-old mothers (OR = 1.07, 1.01–1.13, p = 0.013), mothers who smoked 11 to 20 cigarettes per day (OR = 1.46, 1.33–1.60, p < 0.001), mothers with extreme obesity (OR = 1.32, 1.21–1.43, p < 0.001), mothers with grade II obesity (OR = 1.32, 1.23–1.42, p < 0.001), mothers with pre-pregnancy hypertension (OR = 1.17, 1.04–1.31, p = 0.009), mothers with pre-pregnancy diabetes mellitus (OR = 1.96, 1.71–2.25, p < 0.001), and mothers who used assisted reproductive technology (OR = 1.40, 1.18–1.66, p < 0.001).ConclusionsOur findings suggest a minuscule increase, albeit insignificant, in the trend of CL/P prevalence from 2016 to 2021. Developing CL/P had greater odds among mothers with pre-pregnancy diabetes, smoking, obesity, and pre-pregnancy hypertension mothers along with mothers who used assisted reproductive technology. Isolated CL/P had the highest prevalence in non-Hispanic Whites, American Indian or Alaskan Native and Native Hawaiian and Other Pacific Islanders.

A case-control regression analysis of liver enzymes in obesity-induced metabolic disorders in South Asian females.

Excessive body weight may disrupt hepatic enzymes that may be aggravated by obesity-related comorbidities. The current case-control study was designed to evaluate the extent of liver enzyme alteration in obesity-related metabolic disorders. Obese females with BMI ≥ 30 suffering from metabolic disorders were grouped according to existing co-morbidity and their hepatic enzymes were compared with non-obese healthy females. The resultant data was subjected to analysis of variance and mean difference in liver enzymes were calculated at P = 0.05. Analysis of variance indicated that obese diabetic and obese hypertensive females had almost 96% and 67% increase in the concentration of gamma-glutamyl transferase than control, respectively (P<0.0001). The obese females suffering from diabetes and hypertension exhibited nearly 54% enhancement in alanine transaminase level (P<0.0001) and a 17% increase in aspartate aminotransferase concentration (P = 0.0028). Obesity along with infertility decline liver enzyme production and a 31% significant decline in aspartate aminotransferase was observed while other enzyme concentrations were not significantly altered. Regression analysis was performed on the resultant data to understand the association between liver enzyme alteration and the development of metabolic diseases. Regression analysis indicated that obese diabetic and obese diabetic hypertensive women had 20% production of normal liver enzymes and 80% enzymes produced abnormally. Obese hypertensive and obese infertile females had only 5% and 6% normal production of liver enzymes, respectively. This research leads to the conclusion that the ability of the liver to function normally is reduced in obesity-related diabetes and hypertension. This may be due to inflamed and injured liver and poses a serious threat to developing fatty liver disease and ultimately liver cirrhosis.

Gestational Hypertension and Obesity Affecting Quality of Life: Benefits of DASH Diet During Pregnancy

Aim of Study: Pregnant women are likely to suffer from hypertensive disorder and obesity, emphasizing theintegration of important interventions to improve their quality of life. This study aims to examine the role ofDASH dietary interventions in influencing gestational hypertension and obesity during pregnancy affectinghealth. Methodology: For this purpose, a retrospective study was conducted on a sample of 45 pregnantwomen who were diagnosed with gestational hypertension and obesity during routine obstetric monitoringafter 20 gestational weeks. A total of 25 women formed the control group and 20 women were included inDietary Approaches to Stop Hypertension (DASH) diet group. Statistical analysis was performed and the valuesfor each factor were obtained in the form of mean and standard deviation. Results: The results obtained fromretrospective characteristics of patients showed that there were significant differences within the context ofmaternal age, parity, gestational age at intake, smoking habits, usage of folic acid supplement, gestational birthweeks and gestational weight gain (p &lt; 0.05). However, insignificant results were obtained within the context ofeclampsia, pre-eclampsia, gestational hypertension, obesity and postpartum chronic hypertension (p &gt; 0.05).Recommendation: It is strongly recommended that DASH diet should be given for treating pregnant womenwith hypertensive disorder and fear of obesity, however, this needs further large-scale randomized studies.

The long term effect of renal denervation on ambulatory blood pressure in obese patients with resistant hypertension: A systematic review and meta-analysis of randomized control trials

The global surge in obesity is emerging as a significant contemporary public health challenge, linked with an elevated occurrence of cardiovascular risks like hypertension. Obesity exacerbates the complexity of managing resistant hypertension, as it not only increases the prevalence of hypertension but also contributes to medication resistance. Renal denervation (RDN) stands as a potential approach to address resistant hypertension (RH). A systematic search was conducted through PubMed, Science Direct, and Cochrane Library selecting RCT studies until August 2023. The RCTs showed the long term effect of renal denervation on ambulatory blood pressure in individuals with both obesity and resistant hypertension. Meta-analysis was conducted using Review Manager 5.4 software. There were 9 included RCTs with total 1056 resistant hypertensive patients. Meta-analysis of the difference in changes in ambulatory systolic blood pressure was performed in nine available studies. Renal denervation showed significant ambulatory systolic blood pressure reduction (Mean Difference [MD]: -2.30; 95% CI: -4.34, -0.27; p = 0.03) and non-significant ambulatory diastolic blood pressure reduction (Mean Difference [MD]: -1.07; 95% CI: -2.94, 0.8; p = 0.26). RDN could be an additional treatment for resistant hypertension patients. RDN is not recommended to be performed routinely and not recommended for patients with secondary hypertension or eGFR less than 30 mL/min/1.73 m2.

Potentials of Hyperuricemia and Insulin Levels in Predicting Hypertension in Obese Children: A Cross-sectional Study

Background: Recent studies in humans show that increased uric acid predicts hyperinsulinemia and obesity. Objectives: Our study aimed to investigate whether hyperuricemia and insulin levels predict hypertension in obese children. Methods: This analytical cross-sectional study was conducted on the records of 161 obese children aged 5 to 15 years old based on the defined inclusion criteria. Children's blood pressure, height, weight, FBS (fasting blood sugar), HDL (high-density lipoprotein), LDL (low-density lipoprotein), TG (triglyceride), HbA1c (hemoglobin A1c), urine albumin, creatinine, insulin levels, and uric acid were measured. Data were analyzed by SPSS software. The significance level was considered P &lt; 0.05. Results: According to the data obtained from this study, the mean of SBP (systolic blood pressure) and DBP (diastolic blood pressure) in obese children with hyperuricemia was higher than in obese children without hyperuricemia. The average insulin in obese children and hypertension was higher than in obese children without hypertension, especially in males and the age group of 5 - 10 years. The levels of cholesterol and LDL in hypertensive males were higher than in those with hyperuricemia. HDL was higher in children without hyperuricemia than in children with hyperuricemia. The strongest predictors of uric acid were age (P &lt; 0.001, B = 0.183), HbA1c (P = 0.014, B = 0.255), and cholesterol (P = 0.03, B = -0.007), respectively. Conclusions: Based on this study, there is a relationship between uric acid levels and parameters such as obesity and blood pressure, and the findings showed that increased uric acid predicts hyperinsulinemia and obesity. Therefore, this study indicates that physicians and healthcare workers should consider the level and state of uric acid.

Severe Covid-19 in pregnant and postpartum women admitted to an intensive care unit: A retrospective cohort study

Background SARS-CoV-2 infection is associated with worse maternal and fetal outcomes. This study aims to describe the characteristics of pregnant and postpartum women with severe Covid-19 admitted to ICU. Methods and findings It’s a retrospective cohort study evaluating pregnant and postpartum women referenced to a specialized ICU between May 2020 and June 2022. Covid-19 was confirmed with RT-PCR or rapid antigen test on a nasopharyngeal swab. Variables were described by median and IQR when numerical, and by frequency and percentage when categorical. OR with 95% CI were calculated for the evaluation of factors related to death. P-values were calculated using Pearson’s ꭓ2-test, Fisher’s exact test, Wilcoxon rank sum test, and Kruskall-Wallis test, and statistical significance was established as &lt; 0·05. Missing data were excluded. All statistical analysis were performed using R software version 4.2.2. Of the 101 admissions, 85 (84·2%) were of pregnant women. Obesity (23·0%) and systemic arterial hypertension (13·0%) were the most prevalent medical conditions. Sixty-six (65·3%) were admitted using some type of oxygen support. Forty-seven (46·5%) evolved to mechanical ventilation. There were 61 events considered obstetric complications, with 8 stillbirths/fetal losses. The overall lethality was 15·8%. Pregnancy interruption, need for non-invasive mechanical ventilation, level of oxygen support at admission, prone maneuver, hemodialysis, and healthcare-related infections were factors associated with death. Evaluating the WHO 7-category ordinary scale, there was a trend of increase in the risk of death with higher punctuation, with a statistically significant difference of women with 5 (OR = 7·27; 95% IC = 1·17–194; p = 0·031) or 6 points (OR = 12·0; 95% IC = 1·15–391; p = 0·038) when compared to the ones with 3 points, i.e., of women admitted with a high-flow non-rebreathing mask or invasive mechanical ventilation, compared with the ones admitted at room air, respectively. The main limitations of this study are the relatively small number of participants, and the use of data derived of medical records—which are susceptible to misclassification and variable amounts of missing data. Conclusions Pregnant and postpartum women with severe Covid-19 have high lethality and a high incidence of clinical and obstetric complications. These findings support that this population should be prioritized in public health strategies that address Covid-19.

Особливості артеріальної гіпертензії при ожирінні

Hypertension in obesity is a fairly common problem, and it has its own characteristics. Obesity promotes inflammation in the body, which can damage blood vessels and lead to atherosclerosis, which also contributes to increased blood pressure. Obesity can lead to increased resistance to blood flow in vessels through various mechanisms, including atherosclerosis, inflammation, and other physiological changes. The main direct physiological mechanism of the development and maintenance of arterial hypertension is endothelial dysfunction, which leads to an increase in vascular tone and further remodeling of the vascular wall, and this is a general result of the influence of known external factors.

Caloric restriction improves inflammation in different tissues of the Wistar rats with obesity and 2K1C renovascular hypertension.

Renovascular hypertension (RHV) is the cause of high blood pressure due to left renal ischemia, and obesity and hypertension cause an inflammatory response. This work analyzed the inflammatory and tissue repair profile in renal, hepatic, and cardiac tissues in an animal model of RVH associated with a high-fat diet and caloric restriction. The expressions of RORγ-t, IL-17, T-bet, and TNF-α decreased and IFN-γ increased in the right kidney. In relation to the left kidney, caloric restriction decreased the expression of IFN-γ. In the liver, caloric restriction decreased RORγ-t, IL-17, and T-bet. Hypertension associated with obesity decreased the expression of IFN-γ, while caloric restriction increased. In the right kidney, hypertension and obesity, associated or not with caloric restriction, increased the area of collagen fibers. In the heart and liver, caloric restriction reduced the area of collagen fibers. Caloric restriction increased vascular endothelial growth factor, reduced levels of growth transformation factor-β1 (TGF-β), and increased collagen I in the left kidney. Hypertension/obesity, submitted or not having caloric restriction, increased TGF-β in liver. The results suggest that caloric restriction has beneficial effects in lowering blood pressure and regulating tissue proinflammatory cytokines. However, there was no change in the structure and composition of tissue repair markers.

Relationship between obesity indicators and hypertension–diabetes comorbidity in an elderly population: a retrospective cohort study

BackgroundThe prevalence of obesity, hypertension and diabetes is increasing. Hypertension and diabetes are common complications. Additionally, obesity and hypertension–diabetes comorbidity (HDC) are both closely related to insulin resistance. The aim of this study was to determine the association of obesity indicators with HDC in elderly individuals.MethodsThis retrospective cohort study included 74,955 subjects aged ≥ 60 years living in Xinzheng, Henan Province, from January 2011 to December 2019. The data were collected from the annual health examination dataset. Cox proportional hazard regression models and competing-risk survival regression models were used to examine the relationships between the three indicators and HDC risk.ResultsAfter 346,504 person-years of follow-up, HDC developed in 9,647 subjects. After further adjustments for confounders and death competing risks, compared with a body mass index (BMI) of 18.5–23.9 kg/m2, the fully adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of BMI < 18.5, 24–27.9 and ≥ 28 kg/m2 for HDC morbidity were 0.651(0.538,0.788),1.00,1.396(1.336,1.459) and 1.769(1.666,1.878), respectively. Moreover, participants with abdominal obesity measured via waist circumference (WC) or waist-to-height ratio (WtHR) had a higher risk of HDC (HR:1.513; 95% CI: 1.45,1.578 and HR:1.412;95% CI: 1.353,1.473), respectively, than participants with low WC or with low WtHR. In the joint analyses, the highest risk was observed in participants who were overweight and who had central obesity (HR: 1.721; 95% CI: 1.635, 1.811) compared with the nonoverweight and noncentral obesity groups.ConclusionsIncreased BMI, WC and WtHR were associated with an increased risk of HDC. There was an additive interaction between general body adiposity (as measured via BMI) and central obesity (as measured via WC and WtHR) for HDC. Therefore, reasonable control of BMI, WC and WtHR may be an effective measure to prevent HDC among elderly individuals.

Risk Factors, Trends, and Outcomes Associated With Postpartum Sepsis Readmissions.

To evaluate the prevalence, timing, clinical risk factors, and adverse outcomes associated with postpartum readmissions for maternal sepsis. We conducted a retrospective cohort study of delivery hospitalizations and 60-day postpartum readmissions for females aged 15-54 years with and without sepsis using the 2016-2020 Nationwide Readmissions Database. Temporal trends in sepsis diagnoses during delivery hospitalizations and 60-day postpartum readmissions were analyzed with the National Cancer Institute's Joinpoint Regression Program to estimate the average annual percent change with 95% CIs. Logistic regression models were fit to determine whether delivery hospitalization characteristics were associated with postpartum sepsis readmissions, and unadjusted and adjusted odds ratios with 95% CIs were reported. Adverse outcomes associated with sepsis during delivery hospitalization and readmission were described, including death, severe morbidity, a critical care composite, and renal failure. Overall, 15,268,190 delivery hospitalizations and 256,216 associated 60-day readmissions were included after population weighting, of which 16,399 (1.1/1,000 delivery hospitalizations) had an associated diagnosis of sepsis at delivery, and 20,130 (1.3/1,000 delivery hospitalizations) had an associated diagnosis of sepsis with postpartum readmission. A sepsis diagnosis was present in 7.9% of all postpartum readmissions. Characteristics associated with postpartum sepsis readmission included younger age at delivery, Medicaid insurance, lowest median ZIP code income quartile, and chronic medical conditions such as obesity, pregestational diabetes, and chronic hypertension. Postpartum sepsis readmissions were associated with infection during the delivery hospitalization, including intra-amniotic infection or endometritis, wound infection, and delivery sepsis. Sepsis diagnoses were associated with 24.4% of maternal deaths at delivery and 38.4% postpartum, 2.2% cases of nontransfusion severe morbidity excluding sepsis at delivery and 13.6% postpartum, 15.6% of critical care composite diagnoses at delivery and 30.1% postpartum, and 11.1% of acute renal failure diagnoses at delivery and 36.4% postpartum. Sepsis accounts for a significant proportion of postpartum readmissions and is a major contributor to adverse outcomes during delivery hospitalizations and postpartum readmissions.

Abstract 14569: Chemotherapy in Pregnancy: Assessing the Safety of Adriamycin Administration in Pregnancy Complicated by Breast Cancer

Introduction: Treatment of Pregnancy Associated Breast Cancer (PABC) with radiation and endocrine therapy is challenging due to potential risks to the fetus. Surgical treatment is safe throughout pregnancy, and chemotherapy agents such as anthracyclines are safe during 2 nd and 3 rd trimesters. Case Presentation: A 39-year-old G4P3 female presented at 8 weeks gestation with a twin pregnancy and a right breast mass with bloody nipple discharge. Past medical history was significant for obesity and chronic hypertension. Biopsy of the mass confirmed weakly ER+/PR-/HER2-, node+, stage IIb PABC. After radical mastectomy and axillary lymph node dissection, 4 Adriamycin and Cyclophosphamide (AC) based adjuvant chemotherapy cycles q3 weeks were started at 12 weeks of gestation with a maternal and fetal echocardiogram, brain natriuretic peptide and troponin measurements after each cycle. A baseline echocardiogram revealed cardiomyopathy with an LVEF of 45% and a severely dilated left ventricle. She was New York Heart Association class II at baseline. Carvedilol 6.25 mg BID was started prior to beginning AC and titrated to 12.5 mg BID due to palpitations after 1 st AC cycle. She tolerated 4 AC cycles with no change in EF from baseline, no symptoms of heart failure, and a normal fetal echocardiogram. Weekly Paclitaxel was resumed to complete 12 cycles prior to radiation treatment. She delivered healthy male and female infants at 32 weeks with no complications (M: APGAR 5 and 7; F: APGAR 8 and 7). Postpartum EF decreased to 40%, necessitating titration of carvedilol to 25mg BID and the addition of Sacubitril/Valsartan 24/26 mg BID. Chest pain complaint after delivery prompted evaluation with computed tomography-based angiogram and cardiac magnetic resonance imaging (CMR), ruling out coronary artery disease. Despite this, no evidence of microvascular disease on CMR symptomatic relief was reported on long-acting nitrates. Discussion: This case demonstrates the importance of multidisciplinary patient management, particularly for those with low LVEF who are at higher risk of decompensation. Despite not knowing the etiology of PABC, she could be suffering from thrombotic microangiopathy of small coronary vessels, which explains relief from nitrates.

Effectiveness of health management among individuals at high risk of stroke: An intervention study based on the health ecology model and self-determination theory (HEM-SDT)

BackgroundStroke is the second leading cause of death in adults worldwide. However, up to 80% of strokes can be prevented by modifying risk factors. ObjectiveThe study aims to assess the effectiveness of the Health Ecology Model and Self-Determination Theory (HEM-SDT) based health management intervention among individuals at high risk of stroke. MethodsA randomized controlled trial was conducted in Zhengzhou from May 1st, 2020, to December 31st, 2020. A total of 229 participants were recruited for the study, with 116 individuals at high risk of stroke being randomly assigned to the HEM-SDT health management group, while 113 participants were enrolled in the control group, following their current routine practices. The Generalized Estimating Equation model (GEE) was used to analyze the differences in health knowledge, belief and, behavior between the two groups at the beginning of the intervention, and at 6-month intervals after the intervention. The chi-square test was utilized to assess the control rate of risk factors. ResultsAfter 6 months of intervention, there were significant improvements in health knowledge, behavior, and belief among the participants. The study found significant differences in the interaction effects between time and group for health knowledge (Mean, SD = 25.62 ± 3.88, 95%CI: 7.944–9.604, P＜0.001), health belief (Mean, SD = 87.18 ± 14.21, 95%CI: 23.999–29.887, P＜0.001), and health behavior (Mean, SD = 173.28 ± 24.22, 95%CI: 22.332–36.904, P＜0.001). Additionally, the rates of hypertension, hyperglycemia, dyslipidemia, high or medium risk condition of stroke, obesity, hyperhomocysteinemia, smoking, alcohol consumption, and lack of exercise also showed statistical significance (P＜0.05) after the intervention. ConclusionThe HEM-SDT health management model improves the health knowledge, behavior, and beliefs in people at high risk of stroke and remarkably it shows improvement in modifiable risk factors. It can be recommended for systematic health management in people at high-risk of stroke.

Body Mass Index, Adverse Pregnancy Outcomes, and Cardiovascular Disease Risk.

Obesity is a well-established risk factor for both adverse pregnancy outcomes (APOs) and cardiovascular disease (CVD). However, it is not known whether APOs are mediators or markers of the obesity-CVD relationship. This study examined the association between body mass index, APOs, and postpartum CVD risk factors. The sample included adults from the nuMoM2b (Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-To-Be) Heart Health Study who were enrolled in their first trimester (6 weeks-13 weeks 6 days gestation) from 8 United States sites. Participants had a follow-up visit at 3.7 years postpartum. APOs, which included hypertensive disorders of pregnancy, preterm birth, small-for-gestational-age birth, and gestational diabetes, were centrally adjudicated. Mediation analyses estimated the association between early pregnancy body mass index and postpartum CVD risk factors (hypertension, hyperlipidemia, and diabetes) and the proportion mediated by each APO adjusted for demographics and baseline health behaviors, psychosocial stressors, and CVD risk factor levels. Among 4216 participants enrolled, mean±SD maternal age was 27±6 years. Early pregnancy prevalence of overweight was 25%, and obesity was 22%. Hypertensive disorders of pregnancy occurred in 15%, preterm birth in 8%, small-for-gestational-age birth in 11%, and gestational diabetes in 4%. Early pregnancy obesity, compared with normal body mass index, was associated with significantly higher incidence of postpartum hypertension (adjusted odds ratio, 1.14 [95% CI, 1.10-1.18]), hyperlipidemia (1.11 [95% CI, 1.08-1.14]), and diabetes (1.03 [95% CI, 1.01-1.04]) even after adjustment for baseline CVD risk factor levels. APOs were associated with higher incidence of postpartum hypertension (1.97 [95% CI, 1.61-2.40]) and hyperlipidemia (1.31 [95% CI, 1.03-1.67]). Hypertensive disorders of pregnancy mediated a small proportion of the association between obesity and incident hypertension (13% [11%-15%]) and did not mediate associations with incident hyperlipidemia or diabetes. There was no significant mediation by preterm birth or small-for-gestational-age birth. There was heterogeneity across APO subtypes in their association with postpartum CVD risk factors and mediation of the association between early pregnancy obesity and postpartum CVD risk factors. However, only a small or nonsignificant proportion of the association between obesity and CVD risk factors was mediated by any of the APOs, suggesting APOs are a marker of prepregnancy CVD risk and not a predominant cause of postpartum CVD risk.

Effect and mechanism of Qing Gan Zi Shen decoction on heart damage induced by obesity and hypertension

Ethnopharmacological relevanceQing Gan Zi Shen Decoction (QGZS) is a traditional Chinese formula. It has been extensively used for decades in the treatment of hypertension combined with metabolic diseases, but its cardioprotective effects and underlying mechanisms are poorly understood. Aim of the studyTo explore the cardioprotective effects and potential mechanisms of QGZS in an animal model of obese hypertension. Materials and methodsIn this study, spontaneously hypertensive rats (SHRs) were utilized as an animal model to examine the effects of a high-fat diet and two concentrations of QGZS. Echocardiography, hematoxylin eosin (H&E) staining, and wheat germ agglutinin (WGA) staining were employed to assess the cardiac structure and function of the SHRs throughout a 16-week therapy period. Furthermore, Western blotting (WB) and immunofluorescence (IF) were employed to identify the levels of Nrf2 expression in the mitochondria, cytoplasm, and nucleus of the myocardium. Additionally, transmission electron microscopy and enzyme-linked immunosorbent assay (ELISA) were utilized to measure mitochondrial morphology and pro-inflammatory cytokine levels, respectively. Furthermore, Western blotting (WB), immunohistochemistry (IHC), and immunofluorescence (IF) techniques were employed to quantify the levels of marker proteins associated with myocardial fibrosis, cardiac inflammation, oxidative stress, and mitochondrial dysfunction. ResultsQGZS inhibited weight gain and depressed systolic and mean arterial pressures in high-fat-fed SHRs. Echocardiographic results demonstrated that QGZS prevented the increase in left ventricular mass, restricted the growth of left ventricular diameter, and improved ejection fraction (EF), fractional shortening (FS), and the ratio of early diastolic peak velocity of transmitral flow (E) to late diastolic peak velocity (A) in high-fat-fed SHRs. This suggested that QGZS prevented ventricular remodeling and protected cardiac systolic and diastolic functions. H&E and WGA staining showed that QGZS improved cardiomyocyte disorders and restricted cardiomyocyte hypertrophy. The underlying mechanisms, QGZS attenuated the oxidative stress state, including reducing the generation of reactive oxygen species (ROS) in the myocardium, revitalizing the antioxidant enzyme system, and protecting mitochondrial function. Moreover, QGZS alleviated the pro-inflammatory state in high-fat-fed SHRs. What's more, QGZS significantly increased the expression level of Nrf2 in nuclei and mitochondria in rat heart tissues, exerting a proximate Nrf2 agonist effect. ConclusionsQGZS exerted cardioprotective effects, in part due to its increasing expression of Nrf2 protein in the heart, which promoted Nrf2 nuclear expression.

Association between Morning Surge and Left Ventricular Hypertrophy in Obese Hypertensive Patients.

Weight gain can trigger mechanisms that increase blood pressure. Nevertheless, obesity causes structural changes in the myocardium, including increased ventricular mass, atrial dilatation, and diastolic and systolic dysfunction. Additionally, blood pressure variations, like morning surge (MS) in obese hypertensive patients may have clinical relevance in cardiovascular events. Although morning blood pressure surge is a physiological phenomenon, excess MS can be considered an independent risk factor for cardiovascular events. To evaluate MS values and their association with left ventricular hypertrophy (LVH) and nocturnal dipping (ND) in obese and non-obese hypertensive patients. A cross-sectional study that evaluated BP measurements by ambulatory blood pressure monitoring (ABPM) and the presence of LVH by echocardiography in 203 hypertensive outpatients, divided into two groups: 109 non-obese and 94 obese hypertensives patients. The significance level was set at 0.05 in two-tailed tests. A MS above 20 mmHg by ABPM was detected in 59.2% of patients in the non-obese group and 40.6% in the obese group. LVH was found in 18.1% and 39.3% of patients in the non-obese and obese groups, respectively, p<0.001. In the "obese group", it was observed that a MS>16 mmHg was associated with LVH, [prevalence ratio: 2.80; 95%CI (1.12-6.98), p=0.03]. For the non-obese group, the cut-off point of MS for this association was >22 mmHg. High MS was positively associated with LVH, with a particular behavior in the hypertensive obese group.

Osteoarthritis knee and modifiable cardiovascular risk factors: play in tandem.

To know the frequency of modifiable cardiovascular risk factors in knee osteoarthritis patients. Cross sectional study was done at Department of Rheumatology Indus Medical College, Tando Mohammad Khan from March 25, 2022 to November 24, 2022. Total 246 Osteoarthritis of knee cases with (Kellgren-Lawrence grad-II and above) on x-ray, were selected after demographic details, blood pressure, body mass index and physical examination was done, 5ml of venous blood was drawn by phlebotomist, sent for fasting blood sugar, serum lipids analysis and Framingham 10years risk score was calculated afterward for each participant. In this study males (126) and females (120). Overall (78%) had risk factors, Patients having one CVD risk factor were (22.8%), two risk factors in (21.1%), three in (21.5%), four (9.8%) and five factors in (1.6%) while frequency of modifiable cardiovascular risk shows obesity (45.5%) hypertension (40.2%) intermediate to high risk of framingham score (40%) diabetes mellitus (25%), smoking (17%), high low density lipoproteins (8.1%). In males obesity(54.2%), hypertension (47.5% ) and (45.8%) were on medication, diabetes mellitus(31.7%), smoker(31%), high risk FRS(39.2%), K-L grade-IV(58.4%) and in females: obesity (42%), hypertension (43.7%) and (40.5%) were on medication, diabetes mellitus in (19%), smoking (4%), high risk FRS (13.5%), K-L Grade-4 (42%), significant association of diabetes mellitus, smoking, FRS and K-L grades with gender (p<0.05). In OA knee there is high prevalence of modifiable cardiovascular risk factors and together these imposes a major health risk for future cardiac events and disability.

Vasoactive mediators of hypertension in obesity.

Obesity is associated with hypertension. However, the mechanisms involved are not fully understood. Therefore, we investigated the relationship between obesity and vasoactive mediators. In this cross-sectional study, blood pressure (BP) and vasoactive mediators of hypertension are compared among 135 adults in the nonobese, obese, and morbidly obese body mass index (BMI) ranges (BMI ≤27, 30-40, and >40 kg/m2, respectively). Angiotensinogen, angiotensin II, renin, aldosterone, endothelin-1 (ET-1), neprilysin, atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), cyclic guanosine monophosphate (cGMP), and cyclic adenosine monophosphate (cAMP) levels were measured and their relationship to BP, BMI, race, and gender were investigated. Systolic and diastolic BP (SBP and DSP) were significantly higher in subjects with obesity and morbid obesity compared with nonobese. Angiotensin II, ET-1, and neprilysin were significantly higher in subjects with morbid obesity while BNP was lower. Levels of angiotensinogen, renin, aldosterone, ANP, cGMP, and cAMP did not differ between the groups. BMI was positively related to SBP, DBP, angiotensin II, ET-1, and neprilysin, and inversely related to cGMP and BNP. Age, male gender, and African-American race were associated with higher SBP. SBP was positively related to angiotensin II and ET-1 and inversely related to aldosterone, renin, and cGMP. On multivariate analyses, age, BMI, gender, and race were the main determinants of SBP, and excluding these variables, angiotensin II, aldosterone, renin, and ET-1 accounted for 21.1% ability to predict SBP. Obesity, especially morbid obesity, is associated with higher BP, higher angiotensin II and ET-1 (vasoconstrictors), and lower levels BNP and cGMP (vasodilators). SBP variability can be partly explained by angiotensin II, aldosterone, renin, and ET-1.NEW & NOTEWORTHY Our data show that obesity, especially morbid obesity, is associated with higher blood pressure levels and increases angiotensin II and endotherlin-1 (ET-1) (vasoconstrictors) and lower levels BNP and cGMP (vasodilators) and that systolic blood pressure variability can be partly explained by levels of angiotensin II, aldosterone, renin, and ET-1. The effect of these mediators on blood pressure is in addition to the effects of other known factors related to age, male gender, and AA race.

The Influence of Modifiable Risk Factors on Postoperative Outcomes in Patients Receiving Surgery for Resection for Acoustic Neuroma.

Acoustic neuromas are the most common tumor of the cerebellopontine angle that are associated with a number of symptoms that negatively impact a patient's quality of life. While the mainstay of treatment for these benign tumors remains microsurgical resection, there is limited research exploring how certain modifiable risk factors (MRFs) may affect the perioperative course. The purpose of this study was to investigate how MRFs including malnutrition, obesity, dyslipidemia, uncontrolled hypertension, and smoking may affect postoperative rates of readmission and nonroutine discharges. We utilized the 2016 and 2017 Healthcare Cost and Utilization Project Nationwide Readmissions Database. MRFs were queried using appropriate International Classification of Diseases, Tenth Revision (ICD-10) coding for categories including malnutrition, obesity, dyslipidemia, smoking, alcohol, and hypertension. The statistical analysis was done using RStudio (Version 1.3.959). Chi-squared tests were done to evaluate differences between categorical variables. The Mann-Whitney U-testing was utilized to evaluate for statistically significant differences in continuous data. The "Epitools" package was used to develop logistic regression models for postoperative complications and post hoc receiver operating characteristic curves were developed. Pertaining to nonroutine discharge, predictive models using malnutrition outperformed all other MRFs as well as those with no MRFs (P < .05). In the case of readmission, models using malnutrition outperformed those of obesity and smoking (P < .05). Again, an increase in predictive power is seen in models using dyslipidemia when compared to obesity, smoking, or uncontrolled hypertension. Lastly, models using no MRFs outperformed those of obesity, smoking, and uncontrolled hypertension (P < .05). This is the first study of its kind to evaluate the role of MRFs in those undergoing surgical resection of their acoustic neuroma. We concluded that certain MRFs may play a role in complicating a patient's perioperative surgical course.

Diabetes and pregnancy study (DAPSY): a 10-year single-center cohort study of pregnancies affected by diabetes.

The aim of our study was to investigate to what degree clinical characteristics can contribute to incidence and structure of pregnancy and childbirth complications in women with diabetes, and to reveal key risk factors for adverse outcomes. We conducted a retrospective single-center cohort study from January 2008 through December 2017, including 3069 singleton pregnancies, affected by type 1 diabetes (T1D, n = 498), type 2 diabetes (T2D, n = 214), and gestational diabetes mellitus (GDM, n = 2357). More than 10years duration of T1D associated with increased risk for preterm birth (RR 2.03, 95% CI 1.28-3.20) and preeclampsia (RR 1.57, 95% CI 1.09-2.26). Diabetic nephropathy, same as diabetic proliferative retinopathy, was associated with increased risk of C-section, preeclampsia development, SGA delivery. In patients with T1D who received CSII (12%), we do not report superior outcomes compared to MDI. Pre-pregnancy HbA1c level less than 6.5% reduced the risk of preeclampsia for T1D (RR 0.28, 95% CI 0.19-0.67) and risk of LGA birth for T2D (RR 0.43, 95% CI 0.19-0.92). Achieving glycemic target values by full-term pregnancy reduced the risk of excessive fetal adiposity (RR 0.81 for T1D, RR 0.39 for T2D). For T2D and GDM, the leading risk factors were obesity and chronic hypertension. For patients with GDM, insulin administration and early diagnosis of GDM were the significant risk factors for adverse outcomes. Diabetes during pregnancy is challenging for the clinician, but optimizing glycemic control, treatment regimens, and close attention to comorbidities can help to reduce the risks and ensure appropriate quality diabetes management.
