Management of Cardiovascular Diseases by Short-Chain Fatty Acid Postbiotics.

PURPOSE OF REVIEW: Global health concerns persist in the realm of cardiovascular diseases (CVDs), necessitating innovative strategies for both prevention and treatment. This narrative review aims to explore the potential of short-chain fatty acids (SCFAs)-namely, acetate, propionate, and butyrate-as agents in the realm of postbiotics for the management of CVDs. RECENT FINDINGS: We commence our discussion by elucidating the concept of postbiotics and their pivotal significance in mitigating various aspects of cardiovascular diseases. This review centers on a comprehensive examination of diverse SCFAs and their associated receptors, notably GPR41, GPR43, and GPR109a. In addition, we delve into the intricate cellular and pharmacological mechanisms through which these receptors operate, providing insights into their specific roles in managing cardiovascular conditions such as hypertension, atherosclerosis, heart failure, and stroke. The integration of current information in our analysis highlights the potential of both SCFAs and their receptors as a promising path for innovative therapeutic approaches in the field of cardiovascular health. The idea of postbiotics arises as an optimistic and inventive method, presenting new opportunities for preventing and treating cardiovascular diseases.

Evaluating the association between opium abuse, blood lead levels, and the complexity of coronary artery disease.

Opium abuse and exposure to heavy metals elevate the risk of coronary artery disease (CAD). Therefore, we aimed to determine the association between opium abuse and blood lead levels (BLLs) and the CAD complexity. We evaluated patients with acute coronary symptoms who underwent coronary angiography, and those with >50% stenosis in at least one of the coronary arteries were included. Furthermore, Synergy between PCI with Taxus and Cardiac Surgery I (SYNTAX I) score and BLLs were measured. Based on the opium abuse, 95 patients were subdivided into opium (45) and control (50) groups. Differences in demographics and CAD risk factors were insignificant between the two groups. The median BLLs were remarkably higher in the opium group than in controls (36 (35.7) and 20.5 µg/dL (11.45), respectively, p = 0.003). We also revealed no significant differences in SYNTAX score between the two groups (15.0 (9.0) and 17.5 (14.0), respectively, p = 0.28). Additionally, we found no significant correlation between BLLs and the SYNTAX scores (p = 0.277 and r = -0.113). Opium abuse was associated with high BLLs. Neither opium abuse nor high BLLs were correlated with the complexity of CAD. Further studies are warranted to establish better the relationship between opium abuse, BLLs, and CAD.

Investigation of the association between serum uric acid levels and HEART risk score in patients with acute coronary syndrome.

The association between uric acid (UA) and cardio-metabolic conditions has been recognized for a long time. However, recently, a body of evidence has highlighted the independent role of UA in a series of conditions, including renal and cardiovascular diseases. In this light, data regarding the prognostic role of UA in acute coronary syndrome (ACS) is scarce. A total number of 100 patients, 59 males and 41 females, diagnosed with ACS were recruited in this study. At the time of admission to the hospital, the serum level of UA was measured. In addition, the HEART score was calculated based on each patients' profile. Participants were on average 61.37 ± 12.08 years old. The most prevalent risk factors were hypertension (48%), a history of coronary artery disease (40%), and diabetes mellitus (33%). The average serum level of UA was 5.81 ± 1.81 mg/dl, and the calculated HEART score had a median of six (minimum of two and maximum of ten). A positive yet statistically insignificant correlation was found between the measured UA level and the calculated HEART score (R = 0.375, p = 0.090). However, further studies with larger sample size are required to assess the direct association of UA level with major adverse cardiac events in patients with cardiovascular disease.

Radiation Response of Human Leukemia/Lymphoma Cells was Improved by 7-Geranyloxycoumarin.

Objectives: Adult T-cell leukemia/lymphoma (ATLL) is a blood neoplasm with specific geographic distribution. Although radiotherapy is a palliative treatment that provides long-term local control, single use of radiation leads to complications for patients. To introduce a novel multimodal approach against ATLL, we investigated combinatorial effects of 7-geranyloxycoumarin and radiation in vitro. Methods: Viability of MT-2 cells was determined by resazurin assay upon administration of 7-geranyloxycoumarin alone and followed by radiation. Then, apoptosis was detected by annexin V and propidium iodide, and the expression of candidate genes was analyzed by qPCR. Results: Findings revealed significant (P<.0001) improvement in radiation effects upon 7-geranyloxycoumarin pretreatment, most notably when cells were pretreated with 5 µg/ml 7-geranyloxycoumarin for 96 h, exposed to 6 Gy radiation and recovered for 48 h. These results were confirmed by flow cytometry, as the percentage of early and late apoptotic cells was increased after combinatorial treatment. In addition, significant (P< .0001) changes in CD44, c-MYC, cFLIPL, BMI-1, NF-κB (Rel A), and P53 expression was induced by 7-geranyloxycoumarin and radiation. Conclusions: Current research indicated, for the first time, that combinatorial use of 7-geranyloxycoumarin and ionizing radiation could be considered as an effective therapeutic modality for ATLL.

The effect of trehalose administration on vascular inflammation in patients with coronary artery disease.

BACKGROUND: In recent years, several trials investigated the role of anti-inflammatory agents in reducing cardiovascular events. Trehalose is a natural disaccharide able to reduce inflammation by enhancing macrophage autophagic activity. This action has been demonstrated to attenuate atherosclerotic plaque development in various pro-atherogenic animal models. However, at present, no data about the efficacy of this compound in human subjects have been published. METHODS: We performed a randomized, double-blind trial involving 15 patients with history of myocardial infarction and evidence of systemic inflammation (defined as C-reactive protein > 2 mg/L). The patients were randomly assigned, in 2:1 ratio, to receive either intravenous trehalose (15 g once weekly) or placebo for 12 weeks. The primary efficacy end-point was the change in arterial wall inflammation, assessed by quantifying 18F-FDG PET/CT uptake in carotid arteries and ascending aorta. RESULTS: The MDS TBR change of the index vessel at 3-month follow-up was not significant in treatment and placebo groups. Furthermore, we could not demonstrate any significant difference between the trehalose group and control group in changes of cIMT from baseline to 3 months in the overall population. No significant changes in echocardiographic measurement were noted after trehalose treatment. Except for the change in urea level in placebo group (31.00 ± 6.59 vs. 25.60 ± 6.402 P = 0.038) no other changes were detected after treatment. Also, there was a significant difference between changes in alanine aminotransferase (ALT) trehalose and placebo groups. CONCLUSION: This was the first study that specifically assessed the effects of intravenous trehalose on atherogenesis in human subjects. Trehalose treatment was characterized by an optimal safety profile, but no significant reduction in arterial wall inflammation could be observed. This might be a consequence of the small sample size of this trial. Larger studies are needed to better assess the efficacy of this compound in this clinical context.

Prognostic significance of ATM mutations in chronic lymphocytic leukemia: A meta-analysis.

BACKGROUND: The ATM protein acts as an essential part of the signal transduction pathway upstream of p53 which activates following induction of DNA double-strand breaks (DSBs) and leads to transcriptional proapoptotic genes activation that synchronizes DNA repair. AIM: Several studies have assessed the relationship between ATM mutations and the clinical prognosis in patients with chronic lymphocytic leukemia (CLL). However, its prognostic value has not yet been fully clarified. Hence, we aimed this meta-analysis to investigate the prognostic effect of ATM mutations in patients with CLL. METHOD: The selected clinical studies were extracted from various electronic databases such as PubMed, EMBASE, the Cochrane Library, and Web of Science. In our meta-analysis, Hazard Ratio (HRs) and 95 % confidence interval (CI) for overall survival (OS) were chosen to estimate the prognostic impact of ATM mutations and to compare ATM mutations to those with wild-type. RESULTS: A total of 1299 patients from seven studies were collected. The pooled HRs for OS recommended that patients with CLL had a poorer prognosis HR = 1.24 (95 % CI: 0.97-1.59). The incidence of ATM mutations was found 15.8 % in patients with CLL. Begg's and Egger's tests did not show any significant bias between studies. CONCLUSION: In conclusion, this meta-analysis indicated that ATM mutations were significantly associated with adverse prognostic effect in patients with CLL. However, a randomized controlled prospective study with a large number of patients with different types of ATM mutations is required to assert these results.

A Pilot study on correlation between Zinc and Magnesium serum concentrations and coronary slow flow phenomenon.

BACKGROUND: The pathophysiology of slow flow includes microvascular disorders, endothelial dysfunction, subclinical atherosclerosis, inflammation and anatomical factors. The role of magnesium and zinc in the development of microvascular and endothelial dysfunctions as well as atherosclerosis has been proven in previous studies, and the mechanism of the development has been studied. The aim of current study was to evaluate the serum concentration of zinc and magnesium in patients with epicardial coronary artery slow flow. DESIGN: 125 patients who referred to Ghaem Hospital in Mashhad were selected based on inclusion and exclusion criteria. Magnesium and Zinc levels were evaluated in patients. The plasma levels of studied elements were compared among the different groups and the rate of coronary artery slow flow was evaluated based on the TIMI score. RESULTS: The results of present study indicated that the serum level of Magnesium in the studied groups did not show a significant correlation with rate of coronary artery slow flow (P> 0.05). Serum Zinc concentration was significantly different in the studied groups, which means serum Zinc level in patients without coronary artery occlusion and  without epicardial slow flow were significantly higher than other groups (P> 0.01). CONCLUSION: In the present study, no significant relationship was found between the serum level of zinc and magnesium with the intensity of coronary artery slow flow based on TIMI, and further studies seem to be needed to investigate this relationship.

Intravenous Curcumin Mitigates Atherosclerosis Progression in Cholesterol-Fed Rabbits.

Orally administered curcumin has been found to have a moderate therapeutic effect on dyslipidemia and atherosclerosis. The present study was conducted to determine lipid-modulating and antiatherosclerosis effects of injectable curcumin in the rabbit model of atherosclerosis induced by a high cholesterol diet (HCD). New Zealand white male rabbits were fed on a normal chow enriched with 0.5% (w/w) cholesterol for 8 weeks. Atherosclerotic rabbits were randomly divided into three groups, including a control group receiving intravenous (IV) injection of the saline buffer, two treatment groups receiving IV administration of the injectable curcumin at low (1 mg/kg/week) and high (10 mg/kg/week) over 4 weeks. Plasma lipid parameters, including low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), and total cholesterol (TC) were measured. Aortic arch atherosclerotic lesions were assessed using hematoxylin and eosin (H&E) staining. The low dose of curcumin significantly reduced plasma levels of TC, LDL-C, and TG by -14.19 ± 5.19%, -6.22 ± 1.77%, and - 29.84 ± 10.14%, respectively, and increased HDL-C by 14.05 ± 6.39% (p < 0.05). High dose of curcumin exerted greater lipid-modifying effects, in which plasma levels of TC, LDL-C, and TG were significantly (p < 0.05) decreased by -56.59 ± 10.22%, -44.36 ± 3.24%, and - 25.92 ± 5.57%, respectively, and HDL-C was significantly increased by 36.24 ± 12.5%. H&E staining showed that the lesion severity was lowered significantly in the high dose (p = 0.03) but not significantly (p > 0.05) in the low-dose curcumin groups, compared to control rabbits. The median (interquartile range) of plaque grades in the high dose and low dose, and control groups was found to be 2 [2-3], 3 [2-3], and 4 [3-4], respectively. The injectable curcumin could significantly improve dyslipidemia and alleviate atherosclerotic lesion in HCD-induced atherosclerotic rabbits.

Anterior Column Realignment: Analysis of Neurological Risk and Radiographic Outcomes.

BACKGROUND: Anterior column realignment (ACR) is a less invasive alternative to 3-column osteotomy for the correction of sagittal imbalance. We hypothesized that ACR would correct sagittal imbalance with an acceptable neurological risk. OBJECTIVE: To assess long-term neurological and radiographic outcomes after ACR. METHODS: Patients ≥18 yr who underwent ACR from 2005 to 2013 were eligible. Standing scoliosis radiographs were studied at preoperation, postoperation (≤6 wk), and at minimum 2 yr of follow-up. Clinical/radiographic data were collected through a retrospective chart review, with thoracic 1 spino-pelvic inclination (T1SPi) used as the angular surrogate for sagittal vertical axis. RESULTS: A total of 26 patients had complete data, with a mean follow-up of 2.8 yr (1.8-7.4). Preoperative, sagittal parameters were lumbar lordosis (LL) of -16.1°, pelvic incidence (PI)-LL of 41.7°, T1SPi of 3.6°, and pelvis tilt (PT) of 32.4°. LL improved by 30.6° (P < .001) postoperation. Mean changes in PT (-8.3), sacral slope (8.9), T1SPi (-4.9), and PI-LL (-33.5) were all significant. The motion segment angle improved by 26.6°, from 5.2° to -21.4° (P < .001). Neurological complications occurred in 32% patients postoperation (n = 8; 1 patient with both sensory and motor). New thigh numbness/paresthesia developed in 3 (13%) patients postoperation; only 1 (4%) persisted at latest follow-up. A total of 6 (24%) patients developed a new lower extremity motor deficit postoperation, with 4 (8%) having persistent new weakness at last follow-up. Out of 8 patients with preoperative motor deficit, half saw improvement postoperation and 75% improved by last follow-up. CONCLUSION: There was net motor improvement, with 24% of patients improving and 16% having persistent new weakness at latest follow-up; 60% were unchanged. Radiographic results demonstrate that ACR is a useful tool to treat severe sagittal plane deformity.

Prognostic significance of SF3B1 mutations in patients with myelodysplastic syndromes: A meta-analysis.

Splicing factor 3B subunit 1 (SF3B1) is a complex takes part in intron splicing of pre-mRNA and mutations within it have been reported frequently in myeloid malignancies including myelodysplastic syndromes (MDS). However, its prognostic value has been controversial. Hence, we aimed this meta-analysis to investigate the prognostic effect of SF3B1 mutations in patients with MDS. Several electronic databases were searched in of EMBASE, PubMed, the Cochrane Library and Web of Science (published up to November 2017) to obtain eligible studies. The pooled Hazard Ratio (HRs) and 95% confidence interval (CI) for overall survival (OS) and leukemia-free survival (LFS) as the primary and secondary endpoint, respectively, were chosen and extracted to determine the prognostic impact of SF3B1 mutations and to compare SF3B1 mutations to those with wild-type. Nine cohort studies with a total of 2259 patients were obtained, and the pooled HRs for OS was 0.93 (95% CI: 0.56-1.52, p-value = 0.78) and revealed no significant effect on overall survival of MDS patients by random effect models. Our meta-analysis suggested that SF3B1 has no impact on OS of patients with MDS, however, an adequately designed prospective study with a large number of patients with different type of SF3B1 mutations is needed to confirm these results. Additionally, Begg's and Egger's tests did not show any publication bias.

Wolff-Parkinson-White syndrome and de Winter patterns; An implication for paying special attention to electrocardiogram.

BACKGROUND: Despite recent advances in diagnostic techniques in cardiology, electrocardiography (ECG) has yet remained the first and corner stone of detecting emergency cardiac events including myocardial infarction (MI). There are some ECG findings which are considered as equivalents to MI. De Winter ST-T wave pattern is one of the important ECG findings which is thought to be related to left anterior descending artery occlusion. However, the coexistence of this ECG pattern with other ECG abnormalities are not reported widely. In this report, we discussed a unique case of de Winter ST-T wave pattern in a patient with Wolff-Parkinson-White (WPW) syndrome for the first time. CASE REPORT: A 43-year-old man was referred because of an intermittent typical chest pain. The patient had no cardiovascular risk factor, and was not on any medication; laboratory tests showed elevated and raising troponin I. The first ECG showed pre-excitation (WPW) as well as de winter pattern. According to patient's symptoms and suggestive ECG for probable left anterior descending (LAD) occlusion, emergent angiography was scheduled. The coronary angiography revealed sever LAD artery occlusion. The patient was symptom free after successful percutaneous coronary intervention, and was discharged on medication. The patient remained asymptomatic in 1-year follow-up period. CONCLUSION: Presence of de Winter ST-T changes with other ECG abnormalities is a rare issue, and here we addressed the first case of WPW and de Winter. The physicians should be aware that ECG changes in patients with WPW should not be interpreted as de Winter ST-T changes and vice versa.

The effect of curcumin in prevention of contrast nephropathy following coronary angiography or angioplasty in CKD patients.

INTRODUCTION: Contrast-induced nephropathy (CIN) is the most common cause of iatrogenic acute kidney injury. It is happened more commonly in patients with underlying kidney diseases. It is appeared that the oxidative stress is the main mechanism of contrast nephropathy. Curcumin is suggested as an herbal antioxidant agent, so we decided to assess the effect of curcumin in preventing of this complication in patients with underlying chronic kidney disease (CKD) who need coronary angiography. METHODS AND MATERIALS: We conducted double blind, placebo-controlled clinical trial in 60 moderate to severe CKD patients who underwent coronary angiography or angioplasty. Adjusted dose of Iodixanol was used as contrast agent in all of them. Curcumin or placebo administered orally, 1.5 g daily from 2 days before procedure to 3 days after it. CIN was defined by an increased serum creatinine level≥0.3mg/dl or an increase to ≥1.5 times of the baseline within 48 hours after procedure. Urinary NGAL test was also done the next day after angiography. RESULTS: CIN occurred in 12(20%) of patients, 5(16.7%) in Curcumin group and 7(23.3%) in placebo group (odds ratio [OR], 0.56; 95% confidence interval [CI], 0.18 to 2.36; P0.51). Serum Creatinine was increased after72 hours of intervention from 1.65±0.26 mg/dl to 1.79±0.33 mg/dl in Curcumin group and from 1.61±0.23 mg/dl to 1.86±0.35 in placebo group. There is no significant difference between the mean increase in serum creatinine concentration in the placebo group and Curcumin group (difference of 0.006 mg/dL; 95% CI, - 0.06 to 0.08; P0.85). Urinary NGAL test was significantly higher in patients with AKI (p=0.000), but there weren't differences in its level in two groups (p=0.761)  Conclusion: It is appeared prophylactic oral Curcumin hasn't protective effects on CIN in high risk patients who have undergone coronary procedure.

The association between serum irisin levels and cardiovascular disease in diabetic patients.

BACKGROUND: Cardiovascular disease is the most common cause of mortality and morbidity in diabetic patients. Insulin resistance has been shown to be reduced by the secretion of irisin from muscle and adipose tissues. This study was aimed at determining the relationship between serum irisin levels and angiographically defined coronary artery disease (CAD) in type II diabetic patients. METHODS: In this case-control study, 30 diabetic subjects with angiographically defined CAD were compared with 30 age- and sex-matched diabetic subjects without CAD in terms of clinical and laboratory parameters including serum irisin levels. RESULTS: Serum levels of Irisin were significantly higher in the diabetic group without CAD compared with the group with CAD (P = 0.048). Serum irisin levels showed a significant positive correlation with BMI (r = 0.374, P = 0.004) and fasting insulin (r = 0.303, P = 0.021), and a significant negative correlation with diabetes duration (r = -0.384, P = 0.002). Based on the results of the binary logistic regression model, circulating levels of irisin were associated with the presence of CAD in diabetes (p = 0.038) after adjusting for potential confounders. CONCLUSION: Serum irisin levels were lower in the diabetic patients with cardiovascular complication compared with the uncomplicated diabetic patients. Therefore, additional larger scale studies are needed to determine the role of irisin in monitoring CAD in diabetic patients.

Association of high level of hs-CRP with in-stent restenosis: A case-control study.

BACKGROUND: In-stent restenosis (ISR) is one adverse outcome of coronary stent implantation. Although using drug-eluting stents has reduced the rate of ISR, it remains a major problem. Here, we have investigated the relationship between several patient characteristics including serum high sensitive C-reactive protein (hs-CRP) and ISR. METHODS: This was a case-control study comprising 104 individuals with ISR and 202 patients without. Baseline characteristics were collected using a questionnaire. Fasting blood glucose (FBG), serum triglycerides (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and serum high sensitivity C-reactive protein (hs-CRP) were measured using commercial kits on an auto-analyzer. Data were analyzed using SPSS software and a p value ≤ 0.05 was considered significant. RESULTS: Diabetes mellitus (p < 0.001), stent type (p = 0.005), serum hs-CRP (p = 0.006), FBG (p = 0.038) and serum TG (p = 0.039) were significantly associated with ISR. The association between hs-CRP and ISR remained significant after adjustment for stent type and DM. For patients with a serum hs-CRP <2.64 mg/dL, ISR was only associated with diabetes mellitus (p = 0.016); while for individuals with a serum hs-CRP ≥2.64 mg/dL, ISR was also associated with the presence of diabetes mellitus, serum triglycerides and stent type. CONCLUSION: Higher levels of serum hs-CRP were significantly associated with the occurrence of ISR.

Successful treatment of prosthetic pulmonary valve thrombosis with reteplase: a case report.

Pulmonary prosthetic valve thrombosis is a serious and rare complication with high mortality. Using reteplase for treatment of prosthesis thrombosis is rarely reported. We report the first case in Iran of a thrombosed pulmonary valve in a patient who had undergone repair of tetralogy of Fallot, which was successfully treated twice with intravenous thrombolytic therapy with reteplase.

Dobutamine stress-induced ischemic right ventricular dysfunction in patients with three-vessel coronary artery disease.

BACKGROUND: Dobutamine stress echocardiography (DSE) is a non-invasive technique to detect coronary artery diseases (CAD). There are limited studies on evaluation of the right ventricular function by stress echocardiography. The appropriate evaluation of RV function and early diagnosis of its failure can help to improve outcomes for the patients undergoing cardiac surgery. OBJECTIVE: To determine right ventricular dysfunction in patients with three-vessel CAD by using DSE. METHODS: This cross-sectional study was among 13 patients who were candidates for coronary artery bypass grafting (CABG) referred to Ghaem Hospital, Mashhad, Iran; from September 2015 to May 2016. After a physical examination and initial measures, DSE was performed and echocardiographic parameters were recorded by a cardiologist. Paired-samples t-test was performed using SPSS Software v.16.0 for data analysis. RESULTS: The study included 13 patients (9 males) with a mean age of 65.4±7.6 years. The mean of TAPS was 16.9±4.5 mm and 15.7±2.9 mm before and after stress echocardiography, respectively (p=0.69). Systolic right ventricular (SRV) peak increased from before DSE compared with after DSE (8.0±2.2 vs. 13.7±4.2 mm/s, p<0.001). In addition, after dobutamine injection, right ventricular (RV) cardiac output decreased in 7 patients and one patient was affected by post-ejection shortening. CONCLUSION: It seems that TAPS and RV cardiac output after injection of dobutamine, can be used as markers for the recognition of ischemic RV dysfunction.

Curcumin in heart failure: A choice for complementary therapy?

Heart failure is a major public health concern and one of the most common reasons for a cardiac hospital admission. Heart failure may be classified as having a reduced or preserved ejection fraction and its severity is based on the symptom score. Given the aging population, it is predicted that admissions with heart failure will increase. Whilst pharmacological therapy has improved the associated morbidity and mortality, there is a need for additional therapies to improve the clinical outcome as the death rate remains high. Curcumin is a natural product derived from turmeric that appears to have cardiovascular benefit through a number of mechanisms. In this review, we have assessed the mechanisms by which curcumin may exert its effects in different models of heart failure and show that it has promise as a complementary treatment in heart failure.

Pulsating mass following plain old balloon angioplasty on left anterior descending artery (LAD) via radial access.

BACKGROUND: Trans-radial coronary intervention is a popular technique due to patient comfort and lower complication rate. The main complications of this method are artery spasm, vessel perforation, and formation of pseudo-aneurysm. CASE REPORT: In this report, an unusual complication of radial access angiography was encountered. Shortly after the procedure, the patient's right arm began to swell and a pulsating mass grew over the medial aspect of the arm. Right brachial artery angiography was performed immediately for rolling out brachial artery perforation. There was no evidence of extravasation in brachial angiography. Surprisingly, the mass began to disappear after some active flexion and extension at elbow joint. The same problem occurred again after percutaneous coronary intervention (PCI) on left anterior descending artery (LAD) in this case 2 days later and was resolved by the same maneuver. CONCLUSION: It can be conculded that the brachial artery path was shifted and became entrapped after the procedure due to low soft tissue support.

Curcumin, hemostasis, thrombosis, and coagulation.

Atherothrombotic cardiovascular disease is a major cause of mortality throughout the world. Platelet activation and aggregation play a central role in hemostasis and thrombosis. Herbal medicines have been traditionally used in the management of cardiovascular disease and can help in modifying its progression, particularly in hemostasis and the coagulation process, as well as altering platelet function tests and some coagulation parameters. Curcumin is a polyphenol derived from the Curcuma longa plant and has been used extensively in complementary and alternative medicine, as it is nontoxic and safe with various therapeutic properties. Modern scientific research has demonstrated its anti-inflammatory, antioxidant, anti-carcinogenic, antithrombotic, and cardiovascular protective effects. The present study reviewed previous studies in the literature, which support the positive activity of curcumin in hemostasis, anticoagulation, and fibrinolysis. We also presented molecular mechanisms associated with the antiplatelet and anticoagulant activities of curcumin and potential implications for the treatment of cardiovascular disease.

Preliminary results of anterior lumbar interbody fusion, anterior column realignment for the treatment of sagittal malalignment.

OBJECTIVE Sagittal malalignment decreases patients' quality of life and may require surgical correction to achieve realignment goals. High-risk posterior-based osteotomy techniques are the current standard treatment for addressing sagittal malalignment. More recently, anterior lumbar interbody fusion, anterior column realignment (ALIF ACR) has been introduced as an alternative for correction of sagittal deformity. The objective of this paper was to report clinical and radiographic results for patients treated using the ALIF-ACR technique. METHODS A retrospective study of 39 patients treated with ALIF ACR was performed. Patient demographics, operative details, radiographic parameters, neurological assessments, outcome measures, and preoperative, postoperative, and mean 1-year follow-up complications were studied. RESULTS The patient population comprised 39 patients (27 females and 12 males) with a mean follow-up of 13.3 ± 4.7 months, mean age of 66.1 ± 11.6 years, and mean body mass index of 27.3 ± 6.2 kg/m2. The mean number of ALIF levels treated was 1.5 ± 0.5. Thirty-three (84.6%) of 39 patients underwent posterior spinal fixation and 33 (84.6%) of 39 underwent posterior column osteotomy, of which 20 (60.6%) of 33 procedures were performed at the level of the ALIF ACR. Pelvic tilt, sacral slope, and pelvic incidence were not statistically significantly different between the preoperative and postoperative periods and between the preoperative and 1-year follow-up periods (except for PT between the preoperative and 1-year follow-up, p = 0.018). Sagittal vertical axis, T-1 spinopelvic inclination, lumbar lordosis, pelvic incidence-lumbar lordosis mismatch, intradiscal angle, and motion segment angle all improved from the preoperative to postoperative period and the preoperative to 1-year follow-up (p < 0.05). The changes in motion segment angle and intradiscal angle achieved in the ALIF-ACR group without osteotomy compared with the ALIF-ACR group with osteotomy at the level of ACR were not statistically significant. Total visual analog score, Oswestry Disability Index, and Scoliosis Research Society-22 scores all improved from preoperative to postoperative and preoperative to 1-year follow-up. Fourteen patients (35.9%) experienced 26 complications (15 major and 11 minor). Eleven patients required reoperation. The most common complication was proximal junctional kyphosis (6/26 complications, 23%) followed by vertebral body/endplate fracture (3/26, 12%). CONCLUSIONS This study showed satisfactory radiographic and clinical outcomes at the 1-year follow-up. Proximal junctional kyphosis was the most common complication followed by fracture, complications that are commonly associated with sagittal realignment surgery and may not be mitigated by the anterior approach.
