RESUMO

OBJECTIVE: We investigated the association of high-sensitivity cardiac troponin (Hs-cTn) with all-cause and cardiovascular mortality in non-diabetic individuals. METHODS: This study included 10,393 participants without known diabetes and cardiovascular disease from the US National Health and Nutrition Examination Survey (NHANES). Serum Hs-cTnI and Hs-cTnT concentrations were measured. Prediabetes was defined as fasting blood glucose between 100 and 125 mg/dL or HbA1c between 5.7 and 6.4%. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for mortality risk. Time-dependent receiver operating characteristics (tROC) curves were utilized to measure the predictive performance of the biomarkers. Net Reclassification Improvement (NRI) were calculated to estimate the improvement in risk classification for adding Hs-cTnT or Hs-cTnI to the standard models based on Framingham risk factors. RESULTS: The mean age of the participants was 48.1 ± 19.1 years, with 53.3% being female and 25.8% being prediabetic. After multivariable adjustment, compared to those with Hs-cTnI concentration less than the limit of detection, the HRs (95% CIs) of the participants with Hs-cTnI concentration higher than the 99th upper reference limit were 1.74 (1.35, 2.24) for all-cause mortality and 2.10 (1.36, 3.24) for cardiovascular mortality. The corresponding HRs (95% CIs) for Hs-cTnT were 2.07 (1.53, 2.81) and 2.92 (1.47, 5.80) for all-cause and cardiovascular mortality. There was a significant interaction between prediabetes and Hs-cTnI on the mortality risk; a positive relationship was only observed in prediabetic individuals. No interaction was observed between prediabetes and Hs-cTnT on mortality risk. The Areas Under tROC indicated both Hs-cTnT and Hs-cTnI show better predictive performance in cardiovascular mortality than in all-cause mortality. NRI (95% CI) for adding Hs-cTnT to the standard model were 0.25 (0.21, 0.27) and 0.33 (0.26, 0.39) for all-cause and cardiovascular mortality. The corresponding NRI (95% CI) for Hs-cTnI were 0.04 (0, 0.06) and 0.07 (0.01, 0.13). CONCLUSIONS: Elevated blood levels of Hs-cTnI and Hs-cTnT are associated with increased mortality. Measurement of Hs-cTnT in non-diabetic subjects, particularly those with prediabetes, may help identify individuals at an increased risk of cardiovascular disease and provide early and more intensive risk factor modification.

RESUMO

Hypertension, a prevalent component of metabolic syndrome (MetS), is a well-known risk factor for cardiovascular diseases (CVD). Psychosis is a feature in the schizophrenia spectrum. Meta-analysis suggests that the prevalence of hypertension in schizophrenia and related disorders is 39%. This may be explained by a unidirectional association between hypertension and psychosis, in that psychosis can be a causative factor of hypertension via antipsychotic medication, inflammation and irregular autonomic nervous system activity through multiple mechanisms. Obesity is a side effect of antipsychotic medication and is a risk factor for hypertension. Obesity leads to raised blood pressure, atherosclerosis, increased triglyceride concentration and decreased high-density lipoprotein concentration. Inflammation accompanies hypertension and obesity. In recent years, the role of inflammation in the onset of psychosis has been increasingly recognised. It underlies the immune dysregulation observed in both schizophrenia and bipolar disorder. Interleukin-6, a marker and driver of inflammation, is related to obesity and plays a role in the pathogenesis of MetS and hypertension. The lack of preventive care of hypertension and other MetS risk factors for patients on antipsychotic medication is reflected in the high incidence of CVD in this population. It is important to detect and treat MetS and hypertension in patients with psychosis in order to reduce cardiovascular morbidity and mortality in this population.

RESUMO

In November 2022, the Clinical Practice Guidelines for the Management of Hypertension in China were updated; the definition of hypertension and the target of treatment was changed from 140/90 mm Hg to 130/80 mm Hg. This was prompted by the results of the Strategy of Blood Pressure Intervention in the Elderly Hypertensive Patients (STEP) study, a large multicenter randomized controlled trial conducted in China. STEP echoed the results of the American Systolic Blood Pressure Intervention Trial (SPRINT), and confirmed that intense lowering of blood pressure is on the whole beneficial. This confirmation is important for the Chinese population, in which strokes outnumber myocardial infarctions. It is also reassuring to know that treating adults aged 60 years or older to achieve a systolic blood pressure of <130 mm Hg is safe, while reducing cardiovascular events, stroke and all-cause mortality. Nevertheless, further studies are needed to delineate the risks and benefits in subgroups, such as the elderly with diabetes or a history of stroke.

RESUMO

PURPOSE: To estimate the prevalence of metabolic syndrome (MetS) in the US National Health and Nutrition Examination Survey (NHANES) 2011-18. METHODS: This study included 8183 eligible nonpregnant participants aged ≥20 years from the NHANES 2011-18. MetS was defined as the presence of at least three of the following components: central obesity, reduced high-density lipoprotein cholesterol, elevated triglycerides, elevated blood pressure, and elevated fasting blood glucose. The prevalence of MetS was estimated taking into account the complex sampling. The time trend was evaluated using logistic regression. RESULTS: The total prevalence of MetS increased from 37.6% [95% confidence interval (CI): 34.0%-41.4%] in 2011-12 to 41.8% (95% CI: 38.1%-45.7%) in 2017-18 (P for trend = .028). Among the MetS components, the prevalence of elevated glucose increased from 48.9% (95% CI: 45.7%-52.5%) in 2011-12 to 64.7% (95% CI: 61.4%-67.9%) in 2017-18 (P for trend <.001). The prevalence of MetS in participants with low educational attainment increased from 44.4% (95% CI: 38.8%-50.1%) in 2011-12 to 55.0% (95% CI: 50.8%-59.1%) in 2017-18 (P for trend = .01). CONCLUSION: The prevalence of MetS increased during 2011-18, notably in participants with low educational attainment. Lifestyle modification is needed to prevent MetS and the associated risks of diabetes and cardiovascular disease. Key messages What is already known on this topic: Prevalence of metabolic syndrome is an index of the cardiometabolic health of a population. What this study adds: The prevalence of metabolic syndrome in US adults increased during 2011-18, notably in participants with low educational attainment. How this study might affect research, practice, or policy: Lifestyle modification is needed to prevent metabolic syndrome and the associated risks of diabetes and cardiovascular disease.

RESUMO

Importance: Patients with diabetes are at higher risk for obstructive airway disease (OAD). In recent meta-analyses of post hoc analyses of cardiorenal trials, sodium-glucose cotransporter 2 inhibitors (SGLT2Is) were suggested to reduce the risk of OAD adverse events. However, a clinical investigation of this association is warranted. Objective: This study aimed to investigate the association of SGLT2I use vs dipeptidyl peptidase-4 inhibitor (DPP4I) use with OAD incidence and exacerbation events in patients with type 2 diabetes. Design, Setting, and Participants: This retrospective population-based cohort study used electronic health data from a territory-wide electronic medical database in Hong Kong. Data were collected for patients with type 2 diabetes who were prescribed SGLT2Is or DPP4Is between January 1, 2015, and December 31, 2018. Patients were followed for a median of 2.2 years between January 1, 2015, and December 31, 2020. A prevalent new-user design was adopted to match patients based on previous exposure to the study drugs. Propensity score matching was used to balance baseline characteristics. Exposures: Patients with type 2 diabetes using SGLT2Is (exposure of interest) or DPP4Is (active comparator). Main Outcomes and Measures: The main outcomes were the first incidence of OAD and the count of OAD exacerbations. The risk of incident OAD was estimated using a Cox proportional hazards regression model. The rate of exacerbations was estimated using zero-inflated Poisson regression. Statistical analysis was performed on November 13, 2022. Results: This study included 30 385 patients. The propensity score-matched non-OAD cohort (incidence analysis) consisted of 5696 SGLT2I users and 22 784 DPP4I users, while the matched OAD cohort (exacerbations analysis) comprised 381 SGLT2I users and 1524 DPP4I users. At baseline, 56% of patients in the non-OAD cohort were men and the mean (SD) age was 61.2 (9.9) years; 51% of patients in the OAD cohort were men and the mean age was 62.2 (10.8) years. Compared with DPP4I use, SGLT2I use was associated with a lower risk of incident OAD (hazard ratio, 0.65 [95% CI, 0.54-0.79]; P < .001) and a lower rate of exacerbations (rate ratio, 0.54 [95% CI, 0.36-0.83]; P = .01). The associations were consistent in sex subgroup analysis. Conclusions and Relevance: The findings of this retrospective cohort study of patients with type 2 diabetes in Hong Kong suggest that SGLT2I use was associated with a reduced risk of incident OAD and a lower rate of exacerbations in a clinical setting compared with DPP4I use. These findings further suggest that SGLT2Is may provide additional protective effects against OAD for patients with type 2 diabetes and that further investigation is warranted.

RESUMO

BACKGROUND: Human papillomavirus (HPV) infection has been proposed to be an unconventional risk factor for cardiovascular diseases. We investigated the association between HPV infection and cardiovascular diseases among women with or without HPV vaccination. METHODS: This cross-sectional study included 9,353 women aged between 20 to 59 years old who were tested for vaginal HPV DNA in the National Health and Nutrition Examination Survey (NHANES) 2003-2016. Cardiovascular diseases were defined as the presence of self-reported coronary heart diseases, heart attacks, angina pectoris, and stroke. The association between HPV and cardiovascular diseases was studied using logistic regression, with adjustment for the potential confounders. RESULTS: A total of 40.8% of women were HPV DNA positive; 3.0% had cardiovascular diseases; and 9.0% of women received the HPV vaccine. The presence of vaginal HPV infection was associated with cardiovascular diseases (odd ratio [OR] = 1.66, 95% confidence interval [CI] 1.28-2.16), which remained significant (OR = 1.54, 95% CI 1.15-2.08) after adjustment for sociodemographic characteristics, lifestyle behaviors, medical history, family history of cardiovascular diseases, and antihypertensive drugs. The association was absent among those who were vaccinated against HPV (OR= 0.50, 95% CI 0.07-3.51) but present among those who were not (OR = 1.63, 95% CI 1.18-2.25). CONCLUSIONS: There was an association between HPV infection and cardiovascular diseases. This association was not significant among women vaccinated against HPV. The effect of HPV vaccination on cardiovascular diseases requires further investigation.

RESUMO

CONTEXT: Individuals with type 2 diabetes mellitus (DM) have an increased risk of pneumonia and septic shock. Traditional glucose-lowering drugs have recently been found to be associated with a higher risk of infections. It remains unclear whether sodium-glucose cotransporter 2 inhibitors (SGLT2is), which have pleiotropic/anti-inflammatory effects, may reduce the risk of pneumonia and septic shock in DM. METHODS: MEDLINE, Embase, and ClinicalTrials.gov were searched from inception up to May 19, 2022, for randomized, placebo-controlled trials of SGLT2i that included patients with DM and reported outcomes of interest (pneumonia and/or septic shock). Study selection, data extraction, and quality assessment (using the Cochrane Risk of Bias Assessment Tool) were conducted by independent authors. A fixed-effects model was used to pool the relative risk (RRs) and 95% CI across trials. RESULTS: Out of 4568 citations, 26 trials with a total of 59 264 patients (1.9% developed pneumonia and 0.2% developed septic shock) were included. Compared with placebo, SGLT2is significantly reduced the risk of pneumonia (pooled RR 0.87, 95% CI 0.78-0.98) and septic shock (pooled RR 0.65, 95% CI 0.44-0.95). There was no significant heterogeneity of effect size among trials. Subgroup analyses according to the type of SGLT2i used, baseline comorbidities, glycemic control, duration of DM, and trial follow-up showed consistent results without evidence of significant treatment-by-subgroup heterogeneity (all Pheterogeneity > .10). CONCLUSION: Among DM patients, SGLT2is reduced the risk of pneumonia and septic shock compared with placebo. Our findings should be viewed as hypothesis generating, with concepts requiring validation in future studies.

RESUMO

BACKGROUND & AIMS: The prevalence of nonalcoholic fatty liver disease (NAFLD) has reached epidemic proportions globally as a result of the rapid increase in obesity. However, there is no Food and Drug Administration-approved pharmacotherapy available for NAFLD. This study investigated the role of autotaxin, a secreted enzyme that hydrolyzes lysophosphatidylcholine to produce lysophosphatidic acid (LPA), in the pathogenesis of NAFLD and to explore whether genetic or pharmacologic interventions targeting autotaxin ameliorate NAFLD. METHODS: The clinical association of autotaxin with the severity of NAFLD was analyzed in 125 liver biopsy-proven NAFLD patients. C57BL/6N mice or fibroblast growth factor 21 (FGF21)-null mice were fed a high-fat diet or a choline-deficient diet to investigate the role of the autotaxin-FGF21 axis in NAFLD development by hepatic knockdown and antibody neutralization. Huh7 cells were used to investigate the autocrine effects of autotaxin. RESULTS: Serum autotaxin levels were associated positively with histologic scores and NAFLD severity. Hepatocytes, but not adipocytes, were the major contributor to increased circulating autotaxin in both patients and mouse models with NAFLD. In mice, knocking-down hepatic autotaxin or treatment with a neutralizing antibody against autotaxin significantly reduced high-fat diet-induced NAFLD and high fat- and choline-deficient diet-induced nonalcoholic steatohepatitis and fibrosis, accompanied by a marked increase of serum FGF21. Mechanistically, autotaxin inhibited the transcriptional activity of peroxisome proliferator-activated receptor α through LPA-induced activation of extracellular signal-regulated kinas, thereby leading to suppression of hepatic FGF21 production. The therapeutic benefit of anti-autotaxin neutralizing antibody against NAFLD was abrogated in FGF21-null mice. CONCLUSIONS: Liver-secreted autotaxin acts in an autocrine manner to exacerbate NAFLD through LPA-induced suppression of the peroxisome proliferator-activated receptor α-FGF21 axis and is a promising therapeutic target for NAFLD.

RESUMO

OBJECTIVE: Hypertension and arthritis are two common diseases in the general population, with multiple common risk factors. This study aimed to assess the association between hypertension (HTN) and arthritis. PATIENTS AND METHODS: This cohort study included 48,372 eligible non-pregnant participants aged ≥ 20 years who had valid data on hypertension and arthritis from the National Health and Nutrition Examination Survey (NHANES) 1999-2018. The association between hypertension and arthritis was studied by logistic regression, adjusting for demographics, socioeconomic factors, excess sodium intake, physical activity, ever smoking, diabetes status and body mass index (BMI). RESULTS: Among the participants, 48.0% (95% CI: 47.2-48.9) had hypertension and 24.5% (95% CI: 23.8-25.3) had self-reported arthritis. Hypertension was associated with arthritis [OR = 2.90, (95% CI: 2.74-3.07), p < 0.01], which remained significant [OR = 1.27, (95% CI:1.18-1.37), p < 0.01] after adjustments. Stratified by the types of arthritis, the association remained significant in rheumatoid arthritis (RA) [OR = 1.25, (95% CI: 1.11-1.41), p < 0.01] and osteoarthritis (OA) [OR = 1.32, (95% CI: 1.16-1.50); p < 0.01]. There was no clear association between hypertension and OA in participants aged 60 years old and above [OR = 1.08, (95% CI: 0.92-1.26); p = 0.37]. CONCLUSIONS: In this large nationally representative survey over 20 years, arthritis, including both RA and OA, was strongly associated with hypertension. Our study demonstrates a need for hypertension screening and blood control among patients with arthritis.Key MessagesArthritis was associated with hypertension.Both rheumatoid arthritis and osteoarthritis are strongly associated with hypertension.There is an urgency for hypertension screening and blood control among patients with arthritis.

RESUMO

INTRODUCTION: Obesity is a public health crisis in the USA. This study aimed to estimate the prevalence of obesity and severe obesity in US children and adolescents and identify novel targetable risk factors associated with childhood obesity. METHODS: From the US National Health and Nutrition Examination Survey from 1999 to 2018, 35,907 children aged 2-19 with body mass index (BMI) data were included. Obesity and severe obesity were defined as BMI ≥95th percentile and ≥120% of 95th percentile of US Centers for Disease Control and Prevention growth charts, respectively. Trends in the prevalence of obesity and subgroup analyses according to socioeconomic factors and language used in the interview were analyzed. RESULTS: The prevalence of obesity and severe obesity increased from 14.7 [95% confidence interval: 12.9-17.0]% to 19.2 [17.2-21.0]% and 3.9 [2.9-5.0]% to 6.1 [4.8-8.0]% in 1999-2018, respectively (p = 0.001 and p = 0.014, respectively). In 2017-2018, the prevalence of obesity among children from Spanish-speaking households was 24.4 [22.4-27.0]%, higher than children from English-speaking households (p = 0.027). CONCLUSION: The prevalence of childhood obesity kept increasing in 1999-2018. The problem is worse in children from Spanish-speaking households. Novel and targeted public health intervention strategies are urgently warranted to effectively halt the rising epidemic of childhood obesity.

RESUMO

CONTEXT: Diabetic kidney disease is a major burden among diabetic patients. Sodium-glucose cotransporter 2 inhibitors (SGLT2is) were shown to reduce renal outcomes in clinical trials and real-world studies. However, head-to-head comparisons with individual classes of glucose-lowering agents warranted further investigation. OBJECTIVE: This work aimed to investigate the associations between SGLT2is use vs dipeptidyl peptidase-4 inhibitors (DPP4is) use and 4 renal outcomes: end-stage renal disease (ESRD), albuminuria, acute renal failure (ARF), and the rate of estimated glomerular filtration rate (eGFR) change using a territory-wide electronic medical database in Hong Kong. METHODS: For this retrospective cohort study, the "prevalent new-user" design was adopted to account for previous exposure to study drugs. Propensity score matching was used to balance baseline characteristics. Electronic health data of type 2 diabetes patients using SGLT2is and DPP4is between 2015 and 2018 were collected. RESULTS: The matched cohort consisted of 6333 SGLT2is users and 25 332 DPP4is users, with a median follow-up of 3.8 years. Compared to DPP4is, SGLT2is use was associated with lower risks of ESRD (hazard ratio [HR]: 0.51; 95% CI, 0.42-0.62; P < .001) and ARF (HR: 0.59; 95% CI, 0.48-0.73; P < .001), and a slower decline in eGFR. The associations remained statistically significant among patients with or without rapid eGFR decline and patients who added or switched to SGLT2is from DPP4is. The association with albuminuria was inconsistent across analyses. CONCLUSION: Compared to DPP4is, SGLT2is use was associated with reduced risks of ESRD and ARF, and a slower eGFR decline in a real-world setting. The associations remained statistically significant in patients with or without preindex rapid eGFR decline.

RESUMO

BACKGROUND: Little is known whether patients with lower health literacy could retain the practice and knowledge of home blood pressure monitoring (HBPM) after an educational programme. METHODS: A cluster randomised controlled trial in five primary care clinics recruited participants with uncontrolled hypertension. Clinics were randomised either to a HBPM group education (Risk Assessment and Management Programme (RAMP-group), or individual counselling of self-management (RAMP-individual). Health literacy was assessed by the Chinese Health Literacy Scale for Chronic Care. Practice and knowledge of HBPM were surveyed by a 10-item HBPM knowledge checklist and patient record review 6 months after interventions. Predictors for regular HBPM and good HBPM knowledge were assessed by multivariate logistic regression models. RESULTS: 287 participants (RAMP-group: 151; RAMP-individual: 136) were follow-up for 6 months. 272 participants completed the knowledge questionnaires (response rate 94.8%). 67.8% of the participants performed HBPM regularly, and there was no statistical difference between both interventions. Age more than 65 (adjusted odds ratios (aOR) 2.58, 95% CI 1.37 to 4.86, p=0.003), not working (aOR 2.34, 95% CI 1.10 to 4.97, p=0.027)and adequate health literacy (aOR 2.25, 95% CI 1.28 to 3.95, p=0.005) predicted regular HBPM. Participants in RAMP-group demonstrated a significant lower body weight than those in RAMP-individual (-0.3±2.0 kg vs +0.7 ±1.7 kg, p<0.001).The RAMP-group participants were eight times more likely to have full HBPM knowledge score than the RAMP-individual participants (aOR 8.46, 95% CI 4.68 to 15.28, p<0.001). CONCLUSION: Patients could retain HBPM knowledge better after RAMP-group than RAMP-individual. Older, retired and patients with adequate health literacy were more likely to continue weekly HBPM 6 months after education. TRIAL REGISTRATION NUMBER: NCT02551393.

RESUMO

Diuretic-induced hypokalaemia is a common and potentially life-threatening adverse drug reaction in clinical practice. Previous studies revealed a prevalence of 7%-56% of hypokalaemia in patients taking thiazide diuretics. The clinical manifestations of hypokalaemia due to diuretics are non-specific, varying from asymptomatic to fatal arrhythmia. Diagnosis of hypokalaemia is based on the level of serum potassium. ECG is useful in identifying the more severe consequences. A high dosage of diuretics and concomitant use of other drugs that increase the risk of potassium depletion or cardiac arrhythmias can increase the risk of cardiovascular events and mortality. Thiazide-induced potassium depletion may cause dysglycaemia. The risk of thiazide-induced hypokalaemia is higher in women and in black people. Reducing diuretic dose and potassium supplementation are the most direct and effective therapies for hypokalaemia. Combining with a potassium-sparing diuretic or blocker of the renin-angiotensin system also reduces the risk of hypokalaemia. Lowering salt intake and increasing intake of vegetables and fruits help to reduce blood pressure as well as prevent hypokalaemia.

RESUMO

CONTEXT: Patients with diabetes are at a higher risk of pneumonia and pneumonia mortality. Sodium glucose co-transporter 2 inhibitors (SGLT2is), the latest class of glucose-lowering agents, were shown to reduce the risk of pneumonia in clinical trials. However, the real-world effectiveness of SGLT2is on the risk of pneumonia is largely unknown. OBJECTIVE: To investigate the associations between SGLT2is use and the risk of pneumonia and pneumonia mortality compared with dipeptidyl peptidase-4 inhibitors (DPP4is) using an electronic medical database in Hong Kong. DESIGN: A retrospective cohort study. The "prevalent new-user" design was adopted to account for the previous exposure to the study drugs being compared. Propensity score (PS) matching (1:4) was used to balance the baseline characteristics of the 2 groups. SETTING AND PARTICIPANTS: Electronic health data of type 2 diabetes patients using SGLT2is and DPP4is between 2015 and 2018 was collected from the Clinical Data Analysis and Reporting System. MAIN OUTCOME MEASURES: Pneumonia incidence and mortality. RESULTS: The PS-matched cohort consisted of 6664 users of SGLT2is and 26 656 users of DPP4is, with a mean follow-up of 3.8 years. Poisson regression showed that SGLT2is use was associated with lower risk of pneumonia compared with DPP4is with an absolute rate difference of 4.05 per 1000 person-years (95% CI, 2.61-5.51). The corresponding incidence rate ratio was 0.71 (95% CI, 0.62-0.81). Similar reduction in risk of pneumonia death was observed (hazard ratio 0.57; 95% CI, 0.42-0.77). CONCLUSION: Compared with DPP4is, SGLT2is use was associated with a reduced risk of pneumonia and pneumonia mortality in a real-world setting.

RESUMO

BACKGROUND: Emerging evidence showed that bone metabolism and cardiovascular disease (CVD) are closely related. We previously observed a potential immediate risk of cardiovascular mortality after hip fracture. However, whether there is an immediate risk of cardiovascular events after hip fracture is unclear. The aim of this study was to evaluate the risk for major adverse cardiovascular events (MACEs) between patients having experienced falls with and without hip fracture. METHODS: This retrospective population-based cohort study used data from a centralized electronic health record database managed by Hong Kong Hospital Authority. Patients having experienced falls with and without hip fracture were matched by propensity score (PS) at a 1:1 ratio. Adjusted associations between hip fracture and risk of MACEs were evaluated using competing risk regression after accounting for competing risk of death. RESULTS: Competing risk regression showed that hip fracture was associated with increased 1-year risk of MACEs (hazard ratio [HR], 1.27; 95% confidence interval [CI], 1.21-1.33; p < .001), with a 1-year cumulative incidence difference of 2.40% (1.94%-2.87%). The HR was the highest in the first 90-days after hip fracture (HR of 1.32), and such an estimate was continuously reduced in 180 days, 270 days, and 1 year after hip fracture. CONCLUSIONS: Hip fracture was associated with increased immediate risk of MACEs. This study suggested that a prompt evaluation of MACE among older adults aged 65 years and older who are diagnosed with hip fracture irrespectively of cardiovascular risk factors may be important, as early management may reduce subsequent risk of MACE.
