Abstract
Determining the factors that contribute to making a reliable prediction of the metabolic syndrome will provide a deeper understanding of the medical indices involved in the prediction and assist in early diagnosis and treatment of patients. The study examined the optimal number of National cholesterol education program adult treatment panel (NCEP ATP) III indices needed to make a reliable prediction of the syndrome, whether each of the five NCEP ATP III indices for predicting the syndrome is equally important and whether a reliable prediction can be made using calculated blood pressure indices - estimated mean arterial pressure and pulse pressure - instead of NCEP ATP III blood pressure indices. The results show that NCEP ATP III indices for determination of the syndrome are not equally important. Moreover, the indices importance and their prediction quality vary according to gender. Optimal results are obtained by using all five NCEP ATP III indices for prediction.

World J Clin Cases 2021; 9:9440-9451. [PMID: 34877279 PMCID: PMC8610887 DOI: 10.12998/wjcc.v9.i31.9440] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 04/15/2021] [Accepted: 09/29/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The identification of risk factors for recurrence in patients with minor ischemic stroke (MIS) is a critical medical need.
AIM To develop a nomogram for individualized prediction of in-hospital recurrence in MIS patients.
METHODS Based on retrospective collection, a single-center study was conducted at the First Affiliated Hospital of Anhui Medical University from January 2014 to December 2019. Univariate and multivariate logistic regression analyses were used to determine the risk factors associated with MIS recurrence. The least absolute shrinkage and selection operator regression was performed for preliminary identification of potential risk factors. Uric acid, systolic blood pressure, serum total bilirubin (STBL), and ferritin were integrated for nomogram construction. The predictive accuracy and calibration of the nomogram model were assessed by the area under the receiver operating characteristic curve (AUC-ROC) and Hosmer-Lemeshow test, respectively.
RESULTS A total of 2216 MIS patients were screened. Among them, 155 were excluded for intravascular therapy, 146 for unknown National Institutes of Health Stroke Scale score, 195 for intracranial hemorrhage, and 247 for progressive stroke. Finally, 1244 patients were subjected to further analysis and divided into a training set (n = 796) and a validation set (n = 448). Multivariate logistic regression analysis revealed that uric acid [odds ratio (OR): 0.997, 95% confidence interval (CI): 0.993-0.999], ferritin (OR: 1.004, 95%CI: 1.002-1.006), and STBL (OR: 0.973, 95%CI: 0.956-0.990) were independently associated with in-hospital recurrence in MIS patients. Our model showed good discrimination; the AUC-ROC value was 0.725 (95%CI: 0.646-0.804) in the training set and 0.717 (95%CI: 0.580-0.785) in the validation set. Moreover, the calibration between nomogram prediction and the actual observation showed good consistency. Hosmer-Lemeshow test results confirmed that the nomogram was well-calibrated (P = 0.850).
CONCLUSION Our present findings suggest that the nomogram may provide individualized prediction of recurrence in MIS patients.

Abstract
Objective To characterise the relationship between fasting blood glucose (FBG) and the
incidence of subsequent vascular events (SVE) during the 6 months following
a mild ischaemic stroke (MIS) in Chinese patients. Methods Data from patients with MIS were retrospectively analysed. The primary
endpoint was an SVE during the 6-month follow-up period. The participants
were allocated to three groups (tertiles), according to their FBG
concentration. Results Of the 260 participants, 51 (19.6%) reported an SVE during the follow-up
period. The incidence of SVE significantly differed among the tertiles of
FBG. The odds ratio (OR) was 2.361 (95% confidence interval [CI]:
1.551–3.594) for FBG as a continuous variable and that for FBG categorised
according to tertile was 13.30 (95% CI: 3.519–50.322) in the fully adjusted
model. Curve fitting showed that the incidence of SVE gradually increased
with increasing FBG, with the highest tertile showing the highest mean
incidence (46.7%; 95% CI: 16.2%–79.9%). In addition, participants with or
without diabetes mellitus, hypertension, headache, dizziness, mild cognitive
impairment or anterior circulation artery lesion showed similar associations
between FBG and the incidence of SVE. Conclusion FBG is an independent predictor of 6-month SVE risk in Chinese patients with
MIS.

Abstract
Stroke is one of the leading causes of death and permanent disability worldwide. Ischemic preconditioning (IPC) is an endogenous protective strategy, which has been reported to exhibit a significant neuroprotective effect in reducing the incidence of ischemic stroke. However, the underlying neuroprotective mechanisms of IPC remain elusive. An increased understanding of the pathogenic mechanisms of stroke and IPC serves to highlight the importance of metabolic reprogramming. In this review, we summarize the metabolic disorder and metabolic plasticity in the incidence and progression of ischemic stroke. We also elaborate how IPC fully mobilizes the metabolic reprogramming to maintain brain metabolic homeostasis, especially for energy and redox homeostasis, and finally protects brain function in the event of an ischemic stroke.

Abstract
BACKGROUND Whether the acute dizziness would be associated with potentially life-threatening event, which was previously unknown. METHODS Between Jan 2014 and Dec 2016, We performed a retrospective survey to investigate the clinical data of patients with acute dizziness from an intensive care unit (ICU) in China. Inclusion criteria for all cases were presented with acute dizziness at onset, and then with a potentially life-threatening event. Baseline data and 30-days outcomes were collected. RESULTS Approximately 1.0% of ICU patients had an acute dizziness with potentially life-threatening events. The median age of patients was 60 years (range 23 to 81 years), male: female ratio was 1.8:1. The causes of acute dizziness included focal cerebral hemorrhage in 15 cases (60%), shock in 7cases (28%), and cerebral infarction in 3 cases (12%). The most frequent potentially life-threatening event was acute brain failure (24/25), and the most common cause leading to brain failure was the lesion enlarged (54.2%, including hematoma enlargement in 8 cases, large area infarction or new infarction in 3 cases, and intraventricular hemorrhage in 2 cases). The second potentially life-threatening event was septic shock/secondary sepsis (45.8%). The fatality rate for all life- threatening events was in 64%. Compared with the survival group, the patients with lesion enlarged (56.3% vs. 11.1%, p < 0.05), acute respiratory failure (93.8% vs. 55.6% p < 0.05), lactate level (5.3 mmol/l vs. 1.3 mmol/l, p < 0.05), and Sequential Organ Failure Assessment (SOFA) score (6.9 vs. 3.4, p < 0.0001) in the non-survival group were significantly higher, while late mean arterial blood pressure (84.6 mmHg vs.124 mmHg, p < 0.0001), GCS score (5.0 score vs. 15 score, p < 0.0001) in the non-survival group were significantly lower. CONCLUSION Acute dizziness with potentially life-threatening events accounts for about 1% of adult ICU patients. Acute dizziness in ICU patients is associated with a high risk of death within 30 days of onset.

Abstract
OBJECTIVE Metabolic syndrome (MS) is a group of risk factors which includes hypertension, hyperglycemia, abnormal cholesterol levels, and obesity. Red blood cell distribution width (RDW) is a parameter that reflects the heterogeneity of erythrocyte volume. But the relationship between MS and RDW is intricate and remains poorly understood. We hypothesized that high RDW was associated with MS via inflammation. Our study aimed to investigate the association between RDW and MS in Chinese elderly large cohort. If RDW had a strong correlation with MS, RDW could become a predictor of MS? METHODS We recruited 10,887 ostensibly healthy participants aged from 60 to 93 (5795 male, 5092 female). Associations between RDW and other variables were assessed by Pearson correlation. Crude and adjusted odds ratio for MS with 95% confidence intervals was calculated by binary logistic regression models. RESULTS In elderly Chinese, RDW was significantly higher in males than in females. The prevalence of both men and women decreased with the rise of RDW. For both sexes, RDW demonstrated positive correlations with age, systolic blood pressure (0.070 in males,0.058 in females), high density lipoprotein(0.027in males,0.064 in females), negative correlations with triglycerides (- 0.120 in males,-0.074 in females) and fasting glucose (- 0.048 in males,-0.016 in females). Notably, we detected the associated reduced risks at the the third and fourth quartile of RDW in males. In women, there was no statistical significance. CONCLUSION We found the adjusted odds ratios of MS was lower at the third and fourth quartile of RDW in males.

Abstract
Background Neuropathic-like knee pain (NKP) is often reported in individuals with knee pain (KP), but the contribution of specific central and peripheral risk factors to NKP has not been studied previously. The aims of the present study were to determine the prevalence of NKP in a community-derived sample with KP and to identify risk factors associated with NKP. Methods A cross-sectional study was undertaken (n = 9506) in the East Midlands community among responders (aged 40+ years) to a postal questionnaire. Questions included KP severity (numerical rating scale) and type (neuropathic versus nociceptive) using the modified painDETECT questionnaire, as well as age, body mass index (BMI), significant knee injury, widespread pain, pain catastrophising and fatigue. Multinomial regression analysis was used to determine ORs and 95% CIs. Risk factors were categorised into central and peripheral, and proportional risk contribution (PRC) and 95% CI were estimated using ROC. Results KP was reported in 28.2% of responders, of whom 13.65% had NKP (i.e., 3.9% of the total population). Women reported more NKP. After adjustment for age, gender, BMI and pain severity, definite NKP showed associations (aOR, 95% CI) with fibromyalgia (4.07, 2.49–6.66), widespread pain (1.93, 1.46–2.53), nodal osteoarthritis (1.80, 1.28–2.53), injury (1.50, 1.12–2.00), pain catastrophising (5.37, 2.93–9.84) and fatigue (5.37, 3.08–9.35) compared with non-NKP participants. Although only central risk factors contributed to NKP (PRC 8%, 95% CI 2.5–12.5 for central vs. PRC 3%, 95% CI −0.25 to 7.5 for peripheral), both central and peripheral risk factors contributed equally to non-NKP (PRC 10%, 95% CI 5–20 for both). Conclusions NKP appears to be driven largely by central risk factors and may require different prevention/treatment strategies. Trial registration ClinicalTrials.gov, NCT02098070.

Abstract
Metabolic syndrome (MetS) is the constellation of metabolic risk factors that might foster development of type 2 diabetes and cardiovascular disease. Abdominal obesity and insulin resistance play a prominent role among all metabolic traits of MetS. Because intervention including weight loss can reduce these morbidity and mortality in MetS, early detection of the severity and complications of MetS could be useful. Recent advances in imaging modalities have provided significant insight into the development and progression of abdominal obesity and insulin resistance, as well as target organ injuries. The purpose of this review is to summarize advances in diagnostic imaging modalities in MetS that can be applied for evaluating each components and target organs. This may help in early detection, monitoring target organ injury, and in turn developing novel therapeutic target to alleviate and avert them.

Abstract
Objectives The body variable associated with the diagnosis of Metabolic Syndrome (MetS) is an elevated waist circumference (WC), although a number of other variables have been suggested. Among these, an elevated waist-to-height ratio (WHtR), ie a value higher than 0.5, that may identify abnormality, independently from height. An elevated WHtR provided the best correlation with MetS in a prior study in a large Italian population. In order to assess the validity of this conclusion, a long-term follow-up study re-examined this population, also in order to detect possible associations with cardiovascular (CV) risk. Methods and results 1,071 subjects with a complete follow-up of over 6 years were evaluated with a comparative assessment of the three anthropometric variables, namely WHtR, WC and body mass index (BMI). WHtR≥ 0.5 had the highest sensitivity for the identification of MetS, both in males and females (94.1% and 86.7% respectively). WHtR was of reduced specificity, occurring, yet less frequently (17.7% in males and 30% in females), in patients without MetS. By contrast, enlarged WC occurred with a lower frequency in male patients who developed MetS (30.2%) whereas in females, frequency was higher than in males (69.3%). Finally, a BMI≥ 25 kg/m2 had intermediate sensitivity and specificity regardless of gender. WC showed the highest odds ratio (2.62, 95%CI: 1.18–5.78) for the prediction of CV occurrence. Conclusion The present study confirms WHtR as an excellent screening tool in identifying MetS carriers, but, different from reports in other countries, it shows a lower specificity in our population.

Abstract
OBJECTIVES Studies have showed the associations between different definitions of metabolic syndrome (MetS) and risk of ischemic stroke were inconsistent. In this study, we compared associations of different MetS definitions with ischemic stroke in Chinese elderly population. METHODS A total of 1713 individuals aged 70-84years from Rugao Longevity and Ageing Study were analyzed. The MetS was defined by four different criteria: Chinese Adult Dyslipidemia Prevention Guide, International Diabetes Federation (IDF), Updated ATPIII (Updated ATPIII) by American heart association/American heart, lung and blood institute (AHA/NHLBI), and Joint Interim Statement(JIS) recommended by IDF and the American heart association/American national institutes of health/American heart, lung and blood institute (AHA/NIH/NHLBI). RESULTS Prevalence of MetS in the whole population was 24.0% (Chinese guide), 32.5% (IDF), 38.8% (Updated ATPIII) and 24.0% (JIS) and in stroke population was 27.1% (Chinese guide), 41.1% (IDF), 48.8% (Updated ATPIII) and 27.1% (JIS), respectively. The agreement between definitions was highest in Updated ATPIII vs. IDF (kappa=0.863). It showed that only definitions of IDF (OR 1.55, 95%CI 1.04-2.31, p=0.031) and Updated ATPIII (OR 1.64, 95%CI 1.11-2.42, p=0.013) were independently associated with risk of ischemic stroke in multivariable logistic regression analysis. The risk of ischemic stroke increased with the increasing of numbers of Mets components in Updated ATPIII (p<0.05). CONCLUSION In this population, Updated ATPIII criteria was a more suitable definition of Mets than definitions of Chinese guide, IDF and JIS for screening high-risk individuals of ischemic stroke, and the additive effects of Mets components might play a greater role than its composition alone in ischemic stroke.
