Long-term prognostic implications of brachial-ankle pulse wave velocity in patients undergoing percutaneous coronary intervention.

Objective: The long-term clinical effect of arterial stiffness in high-risk disease entities remains unclear. The prognostic implications of brachial-ankle pulse wave velocity (baPWV) were assessed using a real-world registry that included patients who underwent percutaneous coronary intervention (PCI). Methods: Arterial stiffness was measured using baPWV before discharge. The primary outcome was net adverse clinical events (NACE), defined as a composite of all-cause death, non-fatal myocardial infarction, non-fatal stroke, or major bleeding. Secondary outcomes included major adverse cardiac and cerebrovascular events (MACCE: a composite of all-cause death, non-fatal myocardial infarction, or non-fatal stroke), and major bleeding. The outcomes were assessed over a 4-year period. Results: Patients (n = 3,930) were stratified into high- and low-baPWV groups based on a baPWV cut-off of 1891 cm/s determined through time-dependent receiver operating characteristic curve analysis. baPWV was linearly correlated with 4-year post-PCI clinical events. The high baPWV group had a greater cumulative incidence of NACE, MACCE, and major bleeding. According to multivariable analysis, the high baPWV groups had a significantly greater risk of 4-year NACE (adjusted hazard ratio [HRadj]: 1.44; 95% confidence interval [CI]: 1.12-1.85; p = 0.004), MACCE (HRadj: 1.40; 95% CI: 1.07-1.83; p = 0.015), and major bleeding (HRadj: 1.94; 95% CI: 1.15-3.25; p = 0.012). Conclusion: In PCI-treated patients, baPWV was significantly associated with long-term clinical outcomes, including ischemic and bleeding events, indicating its value for identifying high-risk phenotypes.

Estimated pulse wave velocity as a forefront indicator of developing metabolic syndrome in Korean adults.

Background/Aims: The predictive value of the estimated pulse wave velocity (ePWV) for the development of metabolic syndrome has not yet been extensively explored. This study aimed to fill this gap by evaluating ePWV as a potential predictor of metabolic syndrome development in middle-aged Korean adults. Methods: Using prospective data obtained from the Ansan-Ansung cohort database, participants without metabolic syndrome at baseline were studied. ePWV was calculated using specific equations based on age and blood pressure. The primary outcome was the incidence of metabolic syndrome during a median follow-up period of 187 months. Results: Among the 6,186 participants, 2,726 (44.1%) developed metabolic syndrome during the follow-up period. ePWV methvalues were categorized into tertiles to assess their predictive value for the development of metabolic syndrome. An ePWV cut-off of 7.407 m/s was identified as a predictor of metabolic syndrome development, with a sensitivity of 0.743 and a specificity of 0.464. Participants exceeding this cut-off, especially those in the third tertile (8.77-14.63 m/s), had a notably higher risk of developing metabolic syndrome. Specifically, the third tertile exhibited a 52.8% cumulative incidence compared with 30.8% in the first tertile. After adjustments, those in the third tertile faced a 1.530-fold increased risk of metabolic syndrome (95% confidence interval, 1.330-1.761). Conclusions: ePWV is a significant predictor of the development of metabolic syndrome. This finding underscores the potential of ePWV as a cardiometabolic risk assessment tool and can thus provide useful information for primary prevention strategies.

Qualitative evaluation of artificial intelligence-generated weight management diet plans.

Importance: The transformative potential of artificial intelligence (AI), particularly via large language models, is increasingly being manifested in healthcare. Dietary interventions are foundational to weight management efforts, but whether AI techniques are presently capable of generating clinically applicable diet plans has not been evaluated. Objective: Our study sought to evaluate the potential of personalized AI-generated weight-loss diet plans for clinical applications by employing a survey-based assessment conducted by experts in the fields of obesity medicine and clinical nutrition. Design setting and participants: We utilized ChatGPT (4.0) to create weight-loss diet plans and selected two control diet plans from tertiary medical centers for comparison. Dietitians, physicians, and nurse practitioners specializing in obesity medicine or nutrition were invited to provide feedback on the AI-generated plans. Each plan was assessed blindly based on its effectiveness, balanced-ness, comprehensiveness, flexibility, and applicability. Personalized plans for hypothetical patients with specific health conditions were also evaluated. Main outcomes and measures: The primary outcomes measured included the indistinguishability of the AI diet plan from human-created plans, and the potential of personalized AI-generated diet plans for real-world clinical applications. Results: Of 95 participants, 67 completed the survey and were included in the final analysis. No significant differences were found among the three weight-loss diet plans in any evaluation category. Among the 14 experts who believed that they could identify the AI plan, only five did so correctly. In an evaluation involving 57 experts, the AI-generated personalized weight-loss diet plan was assessed, with scores above neutral for all evaluation variables. Several limitations, of the AI-generated plans were highlighted, including conflicting dietary considerations, lack of affordability, and insufficient specificity in recommendations, such as exact portion sizes. These limitations suggest that refining inputs could enhance the quality and applicability of AI-generated diet plans. Conclusion: Despite certain limitations, our study highlights the potential of AI-generated diet plans for clinical applications. AI-generated dietary plans were frequently indistinguishable from diet plans widely used at major tertiary medical centers. Although further refinement and prospective studies are needed, these findings illustrate the potential of AI in advancing personalized weight-centric care.

Harnessing Metabolic Indices as a Predictive Tool for Cardiovascular Disease in a Korean Population without Known Major Cardiovascular Event.

BACKGRUOUND: This study evaluated the usefulness of indices for metabolic syndrome, non-alcoholic fatty liver disease (NAFLD), and insulin resistance (IR), as predictive tools for cardiovascular disease in middle-aged Korean adults. METHODS: The prospective data obtained from the Ansan-Ansung cohort database, excluding patients with major adverse cardiac and cerebrovascular events (MACCE). The primary outcome was the incidence of MACCE during the follow-up period. RESULTS: A total of 9,337 patients were included in the analysis, of whom 1,130 (12.1%) experienced MACCE during a median follow-up period of 15.5 years. The metabolic syndrome severity Z-score, metabolic syndrome severity score, hepatic steatosis index, and NAFLD liver fat score were found to significantly predict MACCE at values above the cut-off point and in the second and third tertiles. Among these indices, the hazard ratios of the metabolic syndrome severity score and metabolic syndrome severity Z-score were the highest after adjusting for confounding factors. The area under the receiver operating characteristic curve (AUC) of the 10-year atherosclerotic cardiovascular disease (ASCVD) score for predicting MACCE was 0.716, and the metabolic syndrome severity Z-score had an AUC of 0.619. CONCLUSION: The metabolic syndrome severity score is a highly reliable indicator and was closely associated with the 10-year ASCVD risk score in predicting MACCE in the general population. Given the specific characteristics and limitations of metabolic syndrome severity scores as well as the indices of NAFLD and IR, a more practical scoring system that considers these factors is essential to achieve greater accuracy in forecasting cardiovascular outcomes.

Blood pressure and variability responses to the down-titration of antihypertensive drugs.

OBJECTIVES: Several recent guidelines have proposed the gradual reduction of antihypertensive drugs for patients with well controlled blood pressure (BP). However, no studies have examined alterations in BP variability (BPV) during the down-titration of antihypertensives. This study aims to investigate changes in home BPV during the down-titration of antihypertensives. METHODS: We analyzed 83 hypertensive patients who underwent down-titration of antihypertensives and had available home BP data during the down-titration. Down-titration was performed when home SBP was less than 120 mmHg, regardless of the clinic SBP. Primary exposure variable was the standard deviation (SD) of home BP. RESULTS: Among 83 patients (mean age 66.3 ±â€Š11.9 years; 45.8% men), down-titration led to increase home SBP (from 110.5 to 118.7 mmHg; P  < 0.001), and home DBP (from 68.8 to 72.8 mmHg; P  = 0.001) significantly. There were no significant differences in SDs of SBP [from 6.02 ±â€Š3.79 to 5.76 ±â€Š3.09 in morning, P  = 0.570; from 6.13 ±â€Š3.32 to 6.63 ±â€Š3.70 in evening, P  = 0.077; and from 6.54 (4.80, 8.31) to 6.37 (4.65, 8.76) in home SBP, P  = 0.464] and SDs of DBP during the down-titration of antihypertensive drugs. CONCLUSION: Down-titration of antihypertensive drugs did not have notable impact on clinic BP and home BPV, while significantly increasing home BP. These findings provide important insights indicating that the potential concern related to an increase in BPV in the planned strategy of reducing antihypertensive drugs is not substantial.

Association between Estimated Pulse Wave Velocity and Incident Nonalcoholic Fatty Liver Disease in Korean Adults.

Introduction: Nonalcoholic fatty liver disease (NAFLD) is associated with vascular dysfunction, one of the signs of which is arterial stiffness. Carotid-femoral pulse wave velocity (PWV), which is considered the gold standard measure of arterial stiffness, can be estimated using two commonly assessed clinical variables: age and blood pressure. This study aimed to evaluate the association between estimated PWV (ePWV) and the prevalence and incidence of NAFLD among Korean adults. Methods: This study used data from the Ansan-Ansung cohort study, a subset of the Korean Genome and Epidemiology Study, and included 8,336 adult participants with and without NAFLD at baseline. The participants were subdivided into three tertile groups according to ePWV. Results: At baseline, the prevalence of NAFLD was 10.5, 27.5, and 35.0% in the first (lowest), second, and third (highest) tertiles of ePWV, respectively. During the 18-year follow-up period, 2,467 (42.9%) incident cases of NAFLD were identified among 5,755 participants who did not have NAFLD at baseline. After adjustment for clinically relevant variables, participants in the second (adjusted hazard ratio [HR], 1.25; 95% confidence interval [CI], 1.12-1.40) and third (adjusted HR, 1.42; 95% CI, 1.24-1.64) tertiles of ePWV had a significantly higher risk of incident NAFLD than those in the first tertile. Conclusion: Higher ePWV is independently associated with an elevated risk of NAFLD in the general population.

A prognostic value of estimated pulse wave velocity in idiopathic sudden sensorineural hearing loss.

PURPOSE: Arterial stiffness, represented by estimated pulse wave velocity (ePWV), is the independent surrogate marker for cardiovascular event. The aim of the study was to investigate the significance of ePWV in the treatment outcome of idiopathic sudden sensorineural hearing loss (SSNHL). METHODS: One hundred and ten patients with idiopathic SSNHL who hospitalized between April 2019 and March 2022 were evaluated. Arterial stiffness was calculated with formula for ePWV and other cardiovascular parameters of body mass index (BMI), and serum lipid level was determined. All patients received systemic high-dose steroid therapy and intratympanic steroid injections as a salvage management. Treatment outcome was assessed at 6 months after treatment, and classified as recovery and nonrecovery groups according to hearing recovery. RESULTS: The initial pure-tone hearing threshold was 72.6 ± 23.8 dB and final hearing threshold was 52.63 ± 31.10 dB. After treatment, 60 (54.5%) patients included in recovery group and other 50 (45.5%) were classified as nonrecovery group. Age, days of onset to treatment, BMI, waist circumference, and ePWV were higher in the nonrecovery group compared to recovery group in univariate analysis (p = 0.039, p = 0.049, p = 0.003, p = 0.004, p = 0.007, respectively). In multivariate analysis, days of onset to treatment, BMI, and ePWV were associated with recovery (p = 0.030, p = 0.007, p = 0.022). CONCLUSION: Higher ePWV, a measure of arterial stiffness, was associated with a poor hearing recovery of SSNHL.

Long-term outcomes and adverse effects of teduglutide in patients with short bowel syndrome: Highlighting hyperamylasemia and hyperlipasemia.

PURPOSE: Short bowel syndrome is a malabsorptive condition that occurs due to surgical removal or a congenital absence of a significant portion of the small intestine. Patients with short bowel syndrome often rely on parenteral support for extended periods or even their entire lives. Teduglutide, a glucagon-like peptide-2 analog, has shown promising results in reducing dependency on parenteral support in these patients by promoting intestinal adaptation and enhancing nutrient absorption. However, the long-term safety of teduglutide remains a concern, particularly with respect to its potential for the development of hyperamylasemia and hyperlipasemia. METHODS: This study involved patients who received teduglutide from December 2012 to December 2022 at Boston Medical Center. We evaluated outcomes and adverse events, focusing on hyperamylasemia and hyperlipasemia, through chart review. RESULTS: Thirteen eligible patients were identified who had used teduglutide. Of these, the majority (84.6%) experienced a reduction in parenteral support. A high incidence (72.7%) of nonpathological pancreatic enzyme elevation was observed in patients treated with teduglutide. These elevations were often dose dependent and were not associated with any clinical signs of acute pancreatitis or abnormal imaging findings. CONCLUSION: This study highlights the need for further investigations into the long-term safety of teduglutide and the importance of closely monitoring amylase and lipase levels in patients undergoing treatment with teduglutide.

Electrocardiography score based on the Minnesota code classification system predicts cardiovascular mortality in an asymptomatic low-risk population.

BACKGROUND: The use of a single abnormal finding on electrocardiography (ECG) is not recommended for stratifying the risk of cardiovascular (CV) events in low-risk general populations because of its low discriminative power. However, the value of a scoring system containing multiple abnormal ECG findings for predicting CV death has not been sufficiently evaluated. METHODS: In a prospective community-based cohort study, 8417 participants without atherosclerotic CV diseases (ASCVDs) and any related symptoms were followed for 18 years. The standard 12-lead ECGs were recorded at baseline and the ECG findings were categorized using the Minnesota code classification. CV deaths were defined as death from myocardial infarction (MI), chronic ischemic heart disease, heart failure, fatal arrhythmia, cerebrovascular event, pulmonary thromboembolism, peripheral vascular disease and sudden cardiac arrest and identified using the Korean National Statistical Office (KOSTAT) database. RESULTS: In a multivariate Cox proportional hazard (CPH) model, major and minor ST-T wave abnormalities, atrial fibrillation (AF), Q waves in the anterior leads, the lack of Q waves in the posterior leads, high amplitudes of the left and right precordial leads, left axis deviation and sinus tachycardia were associated with higher risks of CV deaths. The ECG score consisted of these findings showed modest predictive values represented by C-statistics that ranged from 0.632 to 760 during the follow-up and performed better in the early follow-up period. The ECG score independently predicted CV death after adjustment for relevant covariates in a multivariate model, and improved the predictive performance of the 10-year ASCVD risk estimator and a model of conventional risk factors including age, diabetes and current smoking. The combined ECG score (Harrell's C-index: 0.852, 95% confidence interval [CI], 0.828-0.876) composed of the ECG score and the conventional risk factors outperformed the 10-year ASCVD risk estimator (Harrell's C-index: 0.806; 95% CI, 0.780-0.833) and the model of the conventional risk factors (Harrell's C-index: 0.841, 95% CI, 0.817-0.865) and exhibited an excellent goodness of fit between the predicted and observed probabilities of CV death. CONCLUSIONS: The ECG score could be useful to predict CV death independently and may add value to the conventional CV risk estimators regarding the risk stratification of CV death in asymptomatic low-risk general populations.

The ECG score based on the Minnesota code classification can independently predict CV death and significantly improve the predictive power of the conventional CV risk estimators in asymptomatic low-risk general population.The combined ECG score comprised the ECG score, age and the presence of diabetes and current smoking predicted CV mortality more accurately than the conventional SV risk estimators.ECG may still be a viable CV risk stratification tool for population-based health screening projects.

The Use of Phentermine for Obesity in Psychiatric Patients With Antipsychotics.

OBJECTIVE: Phentermine is a commonly used weight-loss agent in the United States, but there is a little information about the use of phentermine for patients with obesity taking antipsychotic medications. METHODS: We gathered 57 patients with obesity taking antipsychotic medications whose phentermine treatment was simultaneous with or after any type of antipsychotic exposure and collected data of clinical information, initial/follow-up anthropometric variables, and adverse events (AEs) for the 6-month study period. RESULTS: In total, the mean body weight reduction (BWR) was 4.45 (7.04) kg, and the mean BWR percent (BWR%) was 3.92% (6.96%) at 6 months. Based on the response to phentermine, the patients were classified into two groups: the responder (n=25; BWR% ≥5%) and nonresponder (n=32; BWR% <5%) groups. The responder group's mean BWR and BWR% were 10.13 (4.43) kg and 9.35% (4.09%), respectively, at 6 months. The responders had higher rates of anticonvulsant combination therapy (ACT; responder, 72.0% vs. non-responder, 43.8%; p=0.033) and a shorter total antipsychotic exposure duration (responder, 23.9 [16.9] months vs. non-responder, 37.2 [27.6] months; p= 0.039). After adjusting age, sex, and initial body weight, ACT maintained a significant association with phentermine response (odds ratio=3.840; 95% confidence interval: 1.082-13.630; p=0.037). In the final cohort, there was no report of adverse or new-onset psychotic symptoms, and the common AEs were sleep disturbances, dry mouth, and dizziness. CONCLUSION: Overall, phentermine was effective and tolerable for patients with obesity taking antipsychotic medications, and ACT (predominantly topiramate) augmented the weight-loss effect of phentermine.

Influence of early dose reduction of ticagrelor on clinical outcomes following percutaneous coronary intervention for complex lesions.

Ticagrelor-based dual antiplatelet therapy (DAPT) provides potent antiplatelet inhibition but may increase the bleeding risk in Asian populations. We investigated the influence of early ticagrelor dose reduction (120 mg) on clinical outcomes in Korean patients undergoing percutaneous coronary intervention (PCI). A multicenter prospective clinical cohort study was conducted with patients who received standard-dose ticagrelor-based DAPT (180 mg) after PCI for complex lesions. Major adverse cardiovascular event (MACE: a composite of cardiovascular death, myocardial infarction, stroke, and repeat revascularization), bleeding, and net adverse clinical events (NACE: a composite of MACE and bleeding) were assessed. Among the 772 patients on standard-dose ticagrelor-based DAPT, 115 (14.8%) switched to low-dose ticagrelor-based DAPT (120 mg) within 6 months. Common reasons for the regimen changes were switching as planned (38.8%), dyspnea (25.5%), and bleeding (23.6%). A multivariable Cox proportional hazard model (CPH) showed that the risks of MACE, bleeding, and NACE were not different between the low-dose and standard-dose groups throughout the entire follow-up period and the period beyond 6 months post-PCI. Time-varying multivariable CPH models of the ticagrelor dose reduction yielded similar results. A reduction of the ticagrelor dose within 6 months after PCI is feasible and safe even in patients with complex lesions harboring a high ischemic event risk.

Evaluating the Compliance, Efficacy, and Cost of Formulated Vitamins Versus Separate Supplements in Post-bariatric Surgery Patients.

OBJECTIVE: Micronutrient deficiencies are common complications after bariatric surgery as alterations to the gastrointestinal tract change absorption. Patients are recommended to take supplements including multivitamins, B complex, calcium, vitamin D, and iron after bariatric surgery, and can take these as specifically formulated vitamins for post-bariatric patients or separate vitamin supplements. We investigated the compliance, efficacy, and cost of specifically formulated vitamins for post-bariatric patients in comparison to separate vitamin supplements. METHODS: We surveyed 126 post-bariatric adult patients between February 1, 2022, and August 31, 2022, who had undergone bariatric surgery between 2014 and 2021 to assess the type of supplements taken, compliance, and cost. Demographics, type of bariatric surgery, and serum micronutrient levels were evaluated for all patients. RESULTS: There were 51 patients taking formulated vitamins and 75 patients taking separate vitamins. The formulated vitamin group demonstrated greater adherence to optimal vitamin dosage (formulated vitamin group, 76.5% vs. separate supplement group, 30.7%; p < 0.001) and higher compliance (formulated vitamin group, 90.2% vs. separate supplement group, 66.7%; p = 0.002). The costs associated with both groups were comparable. No significant difference was observed in the incidence of micronutrient deficiency between the groups. CONCLUSIONS: Our study shows that formulated vitamins do not offer significant difference in micronutrient levels or cost compared to separate standard vitamin supplements. However, formulated bariatric vitamins have improved compliance compared to separate vitamin supplements.

Case report: Exploring teduglutide as a therapeutic option for refractory microscopic colitis: insights and implications.

Microscopic colitis is a chronic inflammatory condition of the colon characterized by chronic watery diarrhea, generally with endoscopically normal or nonspecific findings, and can be diagnosed by histopathological examination of colon mucosal biopsies. Some patients experience severe symptoms that do not respond to conventional medical treatment. A glucagon-like peptide-2 (GLP-2) analog, teduglutide, is used in patients with short bowel syndrome (SBS) dependent on parenteral support. In this case report, we describe a patient with microscopic colitis who demonstrated significant symptom improvement following teduglutide treatment.

Prior bariatric surgery and risk of poor in-hospital outcomes in COVID-19: findings from a National Inpatient Sample.

BACKGROUND: Obesity and obesity-related co-morbidities are risk factors for severe coronavirus disease 2019 (COVID-19). OBJECTIVES: As bariatric surgery effectively addresses obesity-related conditions, we hypothesized that prior bariatric surgery may be associated with a reduced risk of severe COVID-19. Small-scale studies have suggested favorable outcomes; however, large-scale nationwide database studies are scarce. SETTING: A retrospective analysis of the 2020 Healthcare Cost and Utilization Project National Inpatient Sample. METHODS: All patients diagnosed with COVID-19 were examined and stratified by history of bariatric surgery. We performed 1:1 propensity score matching and compared patients with COVID-19 with and without prior bariatric surgery. The primary outcome was in-hospital mortality rate. Secondary outcomes included total hospital costs, length of hospital stay, and intensive treatment needs. Multivariate logistic regression analysis was performed to identify independent factors associated with in-hospital mortality. RESULTS: In-hospital mortality rate was significantly lower in patients with prior bariatric surgery (6.2% versus 8.7%, P = .001). Furthermore, sepsis, acute kidney injury, and mechanical ventilation rates were significantly lower in patients with COVID-19 and prior bariatric surgery, resulting in a reduced need for intensive treatment (12.1% versus 14.9%, P = .005). The total hospitalization costs were lower, and the length of hospital stay was shorter in patients with prior bariatric surgery, demonstrating statistical significance. Old age, male sex, body mass index >50, and co-morbidities were significantly associated with in-hospital mortality in patients with COVID-19 and prior bariatric surgery. CONCLUSIONS: Prior bariatric surgery was independently associated with decreased mortality and better in-hospital outcomes in patients hospitalized for COVID-19.

Clinical and life style factors related to the nighttime blood pressure, nighttime dipping and their phenotypes in Korean hypertensive patients.

BACKGROUND: Non-dipping or reverse dipping patterns are known to be associated with adverse cardiovascular prognosis among the general population and clinical cohort. Few large sized studies have explored factors including sleep duration and sleep quality related to nighttime blood pressure (BP) and nocturnal dipping patterns. METHODS: Among 5,360 patients enrolled  in Korean multicenter nationwide prospective Registry of ambulatory BP monitoring (KORABP), 981 subjects with complete data on sleep duration, sleep quality assessed using a 4-point Likert scale, and clinical variables were included in the analysis. Phenotypes of nighttime BP pattern were categorized as extreme dipper, dipper, non-dipper, and reverse dipper. Hypertension was defined as a 24-h ambulatory BPs were 130/80 mmHg or higher. RESULTS: Among 981 subjects, 221 were normotensive, 359 were untreated hypertensive, and 401 were treated hypertensive. Age of the participants were 53.87 ± 14.02 years and 47.1% were female. In overall patients, sleep duration was 431.99 ± 107.61 min, and one to four points of sleep quality were observed in 15.5%, 30.0%, 30.4%, and 24.2%, respectively. Of the 760 hypertensive patients, extreme dipper, dipper, non-dipper, and reverse dipper were observed in 58 (7.63%), 277 (36.45%), 325 (42.76%), and 100 (13.16%), respectively. In multiple linear regression analysis, sleep duration (ß = 0.0105, p < 0.001) and sleep quality (ß = -0.8093, p < 0.001) were associated with nighttime systolic BP and sleep quality was associated with extent of nighttime systolic BP dipping (ß = 0.7622, p < 0.001) in hypertensive patients. In addition, sleep quality showed positive association with dipper pattern (odds ratio [OR] = 1.16, 95% confidence interval [CI] = 1.03-1.30) and showed negative association with reverse dipper pattern (OR = 0.73, 95% CI = 0.62-0.86) in multiple logistic regression analyses. CONCLUSION: When adjusted covariates, less sleep duration and poor sleep quality were positively associated with nighttime systolic BP. Additionally, sleep quality was the independent associated factor for dipper and reverse dipper phenotypes. The study also found that male sex, low estimated glomerular filtration rate, high ambulatory BP, low office BP, and poor sleep quality were associated with blunted nighttime SBP dipping.

Association between D-dimer and long-term mortality in patients with acute severe hypertension visiting the emergency department.

OBJECTIVE: High levels of D-dimer, a marker of thrombotic events, are associated with poor outcomes in patients with various cardiovascular diseases. However, there has been no research on its prognostic implications in acute severe hypertension. This study investigated the association between D-dimer levels and long-term mortality in patients with severe acute hypertension who visited the emergency department. DESIGN AND METHOD: This observational study included patients with acute severe hypertension who visited the emergency department between 2016 and 2019. Acute severe hypertension was defined as a systolic blood pressure ≥ 180 mmHg or a diastolic blood pressure ≥ 100 mmHg. Among the 10,219 patients, 4,127 who underwent D-dimer assay were analyzed. The patients were categorized into tertiles based on their D-dimer levels at the time of emergency department admission. RESULTS: Among the 4,127 patients with acute severe hypertension, 3.1% in the first (lowest) tertile, 17.0% in the second tertile, and 43.2% in the third (highest) tertile died within 3 years. After the adjustment for confounding variables, the third tertile of the D-dimer group (hazard ratio, 6.440; 95% confidence interval, 4.628-8.961) and the second tertile of the D-dimer group (hazard ratio, 2.847; 95% confidence interval, 2.037-3.978) had a significantly higher risk of all-cause mortality over 3 years than the first tertile of the D-dimer group. CONCLUSIONS: D-dimer may be a useful marker for identifying the risk of mortality among patients with acute severe hypertension who visit the emergency department.

A Case of Abnormal Liver Function Tests in a Patient Receiving Total Parenteral Nutrition.

Hepatic dysfunction is prevalent in patients receiving total parenteral nutrition (TPN), resulting from steatosis, cholestasis, and cholecystitis. Regular assessments and monitoring of TPN patients are essential, even for clinically stable patients on long-term TPN. Furthermore, it is crucial to establish a differential diagnosis for hepatic dysfunction and investigate for other possible causes of elevated liver enzymes and underlying liver conditions. We present the case of a 56-year-old female patient with severe protein-calorie malnutrition on TPN, who exhibited significantly elevated liver enzymes during the routine periodic assessment. Subsequent investigation revealed that the patient had been taking traditional Chinese herbal medications concurrently with TPN. After discontinuing the herbal medications, the patient's liver enzymes returned to normal levels within 3 weeks.

Association of microscopic hematuria with long-term mortality in patients with hypertensive crisis.

BACKGROUND: Microscopic hematuria is associated with increased risk of developing chronic kidney function impairment and even death. However, data on the long-term mortality risk associated with microscopic hematuria among patients with hypertensive crisis are scarce. We hypothesized that microscopic hematuria at initial presentation in patients with hypertensive crisis would be associated with increased long-term mortality. METHODS: This retrospective study included patients admitted to the emergency department between 2016 and 2019 for hypertensive crisis (systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 110 mmHg). Microscopic hematuria was defined as ≥ 3 red blood cells per high-power field on microscopic evaluation of urine. RESULTS: Among 3595 patients, 1359 (37.8%) had microscopic hematuria. The 3-year all-cause mortality in patients with and without microscopic hematuria was 25.5% and 16.3%, respectively. After adjusting for confounding variables, patients with microscopic hematuria (adjusted HR, 1.30; 95% CI 1.10-1.54) showed a significantly higher risk of 3-year all-cause mortality than patients without microscopic hematuria. In a subgroup analysis based on the presence of proteinuria, microscopic hematuria was a significant predictor of all-cause mortality in patients without proteinuria (adjusted HR, 1.61; 95% CI 1.28-2.03) but not in patients with proteinuria. CONCLUSION: Microscopic hematuria was a significant predictor of all-cause mortality in patients with hypertensive crisis. Our study suggests that microscopic hematuria can be a useful prognostic marker and may permit early detection of patients with an increased risk of death. Clinicians in the emergency department should consider screening for kidney function using urine analysis during the initial assessment of patients with hypertensive crisis.

Association between B-type natriuretic peptide and long-term mortality in patients with acute severe hypertension visiting the emergency department.

B-type natriuretic peptide (BNP) is a well-established prognostic factor for cardiovascular disorders. However, the association between BNP levels and mortality in patients with acute severe hypertension remains unclear. This study aimed to investigate the association between BNP levels and long-term mortality in patients with acute severe hypertension visiting the emergency department (ED). This retrospective study included patients aged ≥ 18 years who were admitted to the ED between 2016 and 2019 with acute severe hypertension (systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 100 mmHg). Patients were categorized into tertiles according to BNP levels upon admission to the ED. Of the 3099 patients with acute severe hypertension, 6.4% in the first (lowest) tertile, 24.8% in the second tertile, and 44.4% in the third (highest) tertile of BNP died within 3-years. After adjusting for clinically relevant variables, patients in the second tertile of BNP (adjusted hazard ratio [HR], 2.64; 95% confidence interval [CI], 1.96-3.55), and patients in the third tertile of BNP (adjusted HR 4.18; 95% CI, 3.09-5.64) had a significantly higher risk of 3-year all-cause mortality than those in the first tertile of BNP. Therefore, BNP may be valuable for the initial assessment to identify high-risk patients among those with acute severe hypertension.
