Short-term effects of gastric bypass versus sleeve gastrectomy on high LDL cholesterol: The BASALTO randomized clinical trial.

BACKGROUND: There has been a substantial increase in the use of laparoscopic sleeve gastrectomy (SG) to treat morbid obesity despite observational evidence demonstrating the superiority of Roux-en-Y gastric bypass (RYGB) for reducing low-density lipoprotein (LDL) cholesterol. The main aim was to ascertain whether high LDL cholesterol levels should be considered when selecting the most appropriate surgical procedure for each patient (RYGB or SG). METHODS: In this single-center, randomized clinical trial using intention-to-treat analysis, 38 patients with severe obesity and elevated levels of LDL cholesterol were randomly assigned to undergo RYGB or SG. The primary outcome was LDL cholesterol remission at 12 months, defined as LDL cholesterol < 3.36 nmol/l without lipid-lowering medications. Secondary outcomes included changes in weight, other comorbidities, qualitative lipoprotein traits, cholesterol esters, glycoproteins, cholesterol absorption and synthesis metabolites and complications. RESULTS: Intention-to-treat analysis revealed that LDL cholesterol remission occurred in 66.6% of RYGB patients compared to 27.8% of SG patients (p = 0.019). Among patients completing follow-up, RYGB demonstrated superior remission (80.0% vs. 29.4%, p = 0.005). Exclusive benefits of RYGB included a reduction in large, medium, and small LDL particles. Cholesterol absorption markers showed differential behavior after both techniques: campesterol (Δ -15.2 µg/mg, 95% CI -30.2 to -0.1) decreased after RYGB, and sitosterol (Δ 21.1 µg/mg, 95% CI 0.9 to 41.2), cholestanol (Δ 30.6 µg/mg, 95% CI 14.8 to 57.9) and campesterol (Δ 18.4 µg/mg, 95% CI 4.4 to 32.3) increased after SG. No differences in weight loss, cholesterol esters, glycoproteins, cholesterol synthesis metabolites or postoperative complications were observed between techniques. CONCLUSION: In conclusion, RYGB is superior to SG in terms of short-term of high LDL cholesterol remission. Furthermore, RYGB also led to a greater improvement in lipoprotein parameters that confer an atherogenic profile. Therefore, the presence of elevated levels of LDL cholesterol should be considered when determining the optimal bariatric surgery procedure for each patient.

Acute-to-chronic glycemic ratio as an outcome predictor in ischemic stroke in patients with and without diabetes mellitus.

OBJECTIVE: Elevated plasma glucose levels are common in patients suffering acute ischemic stroke (AIS), and acute hyperglycemia has been defined as an independent determinant of adverse outcomes. The impact of acute-to-chronic glycemic ratio (ACR) has been analyzed in other diseases, but its impact on AIS prognosis remains unclear. The main aim of this study was to assess whether the ACR was associated with a 3-month poor prognosis in patients with AIS. RESEARCH, DESIGN AND METHODS: Retrospective analysis of patients admitted for AIS in Hospital del Mar, Barcelona. To estimate the chronic glucose levels (CGL) we used the formula eCGL= [28.7xHbA1c (%)]-46.7. The ACR (glycemic at admission / eCGL) was calculated for all subjects. Tertile 1 was defined as: 0.28-0.92, tertile 2: 0.92-1.13 and tertile 3: > 1.13. Poor prognosis at 3 months after stroke was defined as mRS score 3-6. RESULTS: 2.774 subjects with AIS diagnosis were included. Age, presence of diabetes, previous disability (mRS), initial severity (NIHSS) and revascularization therapy were associated with poor prognosis (p values < 0.05). For each 0.1 increase in ACR, there was a 7% increase in the risk of presenting a poor outcome. The 3rd ACR tertile was independently associated with a poor prognosis and mortality. In the ROC curves, adding the ACR variable to the classical clinical model did not increase the prediction of AIS prognosis (0.786 vs. 0.781). CONCLUSIONS: ACR was positively associated with a poor prognosis and mortality at 3-months follow-up after AIS. Subjects included in the 3rd ACR tertile presented a higher risk of poor prognosis and mortality. Baseline glucose or ACR did not add predictive value in comparison to only using classical clinical variables.

Resilient Older Subjects with Heterozygous Familial Hypercholesterolemia, Baseline Differences and Associated Factors.

Despite elevated low-density lipoprotein (LDL) cholesterol levels, some older subjects with heterozygous familial hypercholesterolemia (HeFH) do not develop atherosclerotic cardiovascular disease (ACVD) during their lifetime. The factors related to this resilient state have not been fully established. The aim of this study was to evaluate differential characteristics between older HeFH subjects with and without ACVD and factors associated with the presence of ACVD. Subjects were part of the Spanish Atherosclerosis Society Dyslipidemia Registry, and those ≥ 70 years old and with HeFH were included. Baseline characteristics of these subjects with and without ACVD were compared. A multivariate analysis was performed to assess factors associated with the presence of ACVD. A total of 2148 subjects with HeFH were included. Resilient subjects were mostly female, younger and presented fewer comorbidities with respect to the ACVD group. Subjects without ACVD had higher baseline high-density lipoprotein (HDL) cholesterol (55.8 ± 17.1 vs. 47.9 ± 15.4 mg/dL; p < 0.001) and lower lipoprotein(a) [Lp(a)] (53.4 ± 67.9 vs. 66.6 ± 85.6 mg/dL; p < 0.001) levels with respect to those in the ACVD group. Lp(a) and the presence of ≥3 risk factors were associated with the presence of ACVD.

Use of phytosterol-fortified foods to improve LDL cholesterol levels: A systematic review and meta-analysis.

AIMS: The main objective was to assess if foods fortified with phytosterols (PS), including plant sterols and plant stanols, reduce low-density lipoprotein cholesterol (LDL-C) concentrations. The secondary objective was to determine the impact of different factors related to PS administration. DATA SYNTHESIS: The search was carried out in MEDLINE, EMBASE, Web of Science, Scopus and The Cochrane Central Register of Controlled Trials (CENTRAL) databases up to March 2023. The meta-analysis was registered in the PROSPERO database (CRD42021236952). From a total of 223 studies, 125 were included. On average, PS lowered LDL-C 0.55 mmol/L [95% confidence interval (CI) = 10.82-12.67], and this decrease was significantly maintained for all analysed subgroups. A greater reduction in LDL-C levels was detected in relation to a higher daily PS dosage. The food format "Bread, biscuits, cereals", conditioned a lower decrease of 0.14 mmol/L (95%CI -8.71 to -2.16) in LDL-C levels, compared to the predominant food format group of "butter, margarine, spreads". No significant differences were detected with the other subgroups (treatment duration, intake pattern, number of daily intakes and concomitant statin treatment). CONCLUSION: The present meta-analysis supported that the use of PS-fortified foods had a beneficial effect on LDL-C lowering. In addition, it was observed that the factors that influence a decline LDL-C levels were PS dose as well as the food format in which they were consumed.

LDL Cholesterol Reduction Variability with Different Types and Doses of Statins in Monotherapy or Combined with Ezetimibe. Results from the Spanish Arteriosclerosis Society Dyslipidaemia Registry.

PURPOSE: Low-density lipoprotein (LDL) cholesterol reduction by statin therapy is dose-dependent, varies among different statins, and has wide inter-individual variability. The present study aimed to compare mean LDL cholesterol reduction and its variability achieved with different doses of the three statins most frequently used in monotherapy or combined with ezetimibe in a real clinical setting. METHODS: Of 5620 cases with primary hypercholesterolemia on the Spanish Arteriosclerosis Society Registry, 1004 with non-familial hypercholesterolemia and complete information on drug therapy and lipid profile were included. RESULTS: The lowest mean percentage LDL cholesterol reduction was observed with simvastatin 10 mg (32.5 ± 18.5%), while the highest mean percentage LDL reduction was obtained with rosuvastatin 40 mg (58.7 ± 18.8%). As to combined treatment, the lowest and highest mean percentage LDL cholesterol reductions were obtained with simvastatin 10 mg combined with ezetimibe (50.6 ± 24.6%) and rosuvastatin 40 mg combined with ezetimibe (71.6 ± 11.1%), respectively. Factors associated with a suboptimal response were male sex, lower age, body mass index, and baseline LDL cholesterol levels. Combined treatment was associated with less variability in LDL cholesterol reduction (OR 0.603, p < 0.001). CONCLUSION: In a real clinical setting, rosuvastatin was superior to the other statins in lowering LDL cholesterol, both as monotherapy or combined with ezetimibe. Factors associated with a suboptimal response in LDL cholesterol decline were male sex, age, body mass index, and baseline LDL cholesterol levels. Combined treatment was associated with less variability in LDL cholesterol improvement.

Level of understanding and consumption of ultra-processed food in a Mediterranean population: A cross-sectional study.

BACKGROUND AND AIMS: Since the population may not be aware of ultra-processed food (UPF) consumption as a result of ignorance or non-recognition, this study aimed to ascertain the main characteristics of subjects regarding their knowledge of different easily acquired foods through a questionnaire in Google Forms format with 52 questions. Secondary objectives were to determine whether the profile of UPF consumers can be defined based on sex, age, sociodemographic factors, and lifestyle. METHODS AND RESULTS: Responses were received from 1037 participants from a convenience sample; of these, 83 (8.0%) were sporadic or non-users, and 954 (92.0%) were frequent UPF consumers. The participants of the upper tertile correctly matched >12 food items, those of the medium tertile matched 12-9 items, and those of the lower tertile matched <9 items. Factors independently associated with participants who better identified UPF (upper tertile) compared to those of the lower tertile (reference) were female sex (OR: 2.54, 95%CI: 1.70-3.79; p < 0.001), age between 21 and 50 (OR: 3.63, 95% CI: 2.56-5.15; p < 0.001), living with family (OR: 0.64, 95% CI: 0.41-9.96; p = 0.033), and eating more fruit (≥3 pieces/day, OR: 2.30, 95% CI: 1.61-3.27; p < 0.001). CONCLUSIONS: These findings highlight the high consumption and low degree of awareness of UPF among consumers based mainly on food composition.

Impact of statin therapy on LDL and non-HDL cholesterol levels in subjects with heterozygous familial hypercholesterolaemia.

BACKGROUND AND AIMS: Cardiovascular risk in heterozygous familial hypercholesterolaemia (HeFH) is driven by LDL cholesterol levels. Since lipid response to statin therapy presents individual variation, this study aimed to compare mean LDL and non-HDL cholesterol reductions and their variability achieved with different types and doses of the most frequently prescribed statins. METHODS AND RESULTS: Among primary hypercholesterolaemia cases on the Spanish Arteriosclerosis Society registry, 2894 with probable/definite HeFH and complete information on drug therapy and lipid profile were included. LDL cholesterol reduction ranged from 30.2 ± 17.0% with simvastatin 10 mg to 48.2 ± 14.7% with rosuvastatin 40 mg. After the addition of ezetimibe, an additional 26, 24, 21 and 24% reduction in LDL cholesterol levels was obtained for rosuvastatin, 5, 10, 20 and 40 mg, respectively. Subjects with definite HeFH and a confirmed genetic mutation had a more discrete LDL cholesterol reduction compared to definite HeFH subjects with no genetic mutation. A suboptimal response (<15% or <30% reduction in LDL cholesterol levels, respectively with low-/moderate-intensity and high-intensity statin therapy) was observed in 13.5% and, respectively, 20.3% of the subjects. CONCLUSION: According to the LDL cholesterol reduction in HeFH patients, the ranking for more to less potent statins was rosuvastatin, atorvastatin and simvastatin; however, at maximum dosage, atorvastatin and rosuvastatin were nearly equivalent. HeFH subjects with positive genetic diagnosis had a lower lipid-lowering response. Approximately 1 in 5 patients on high-intensity statin therapy presented a suboptimal response.

Effects of Preoperative Quadruple Therapy for Helicobacter pylori on Bariatric Surgery Metabolic Outcomes.

PURPOSE: To assess the effects of Helicobacter pylori (HP) eradication with an omeprazole, clarithromycin, amoxicillin, and metronidazole (OCAM) regimen on the metabolic profile and weight loss 12 months after bariatric surgery (BS). METHODS: Retrospective analysis of a prospective cohort of patients with morbid obesity undergoing BS. HP presence was tested preoperatively by gastric biopsy and treated with OCAM when positive. Short-term metabolic outcomes and weight loss were evaluated. RESULTS: HP infection was detected in 75 (45.7%) of the 164 patients included. OCAM effectiveness was 90.1%. HP-negative patients had a greater reduction in glucose levels at 3 (-14.6 ± 27.5 mg/dL HP-treated vs -22.0 ± 37.1 mg/dL HP-negative, p=0.045) and 6 months (-13.7 ± 29.4 mg/dL HP-treated vs -26.4 ± 42.6 mg/dL HP-negative, p= 0.021) and greater total weight loss (%TWL) at 6 (28.7 ± 6.7% HP-treated vs 30.45 ± 6.48% HP-negative, p= 0.04) and 12 months (32.21 ± 8.11% HP-treated vs 35.14 ± 8.63% HP-negative, p= 0.023). CONCLUSIONS: Preoperative treatment with OCAM has been associated to poorer glycemic and weight loss outcomes after BS. More research is needed on the influence of OCAM on gut microbiota, and in turn, the effect of the latter on metabolic and weight loss outcomes after BS.

Real-World Evidence of Off-Label Use of Commercially Automated Insulin Delivery Systems Compared to Multiple Daily Insulin Injections in Pregnancies Complicated by Type 1 Diabetes.

Aims: To compare glycemic control and maternal-fetal outcomes of women with type 1 diabetes (T1D) using hybrid closed loop (HCL) versus multiple daily insulin injections (MDI) plus continuous glucose monitoring. Methods: Multicenter prospective cohort study of pregnant women with T1D in Spain. We evaluated HbA1c and time spent within (TIR), below (TBR), and above (TAR) the pregnancy-specific glucose range of 3.5-7.8 mmol/L. Adjusted models were performed for adverse pregnancy outcomes, including baseline maternal characteristics and center. Results: One hundred twelve women were included (HCL n = 59). Women in the HCL group had a longer duration of diabetes and higher rates of prepregnancy care. There was no between-group difference in HbA1c in any trimester. However, in the second trimester, MDI users had a greater decrease in HbA1c (-6.12 ± 9.06 vs. -2.16 ± 7.42 mmol/mol, P = 0.031). No difference in TIR (3.5-7.8 mmol/L) and TAR was observed between HCL and MDI users, but with a higher total insulin dose in the second trimester [+0.13 IU/kg·day)]. HCL therapy was associated with increased maternal weight gain during pregnancy (ßadjusted = 3.20 kg, 95% confidence interval [CI] 0.90-5.50). Regarding neonatal outcomes, newborns of HCL users were more likely to have higher birthweight (ßadjusted = 279.0 g, 95% CI 39.5-518.5) and macrosomia (ORadjusted = 3.18, 95% CI 1.05-9.67) compared to MDI users. These associations disappeared when maternal weight gain or third trimester HbA1c was included in the models. Conclusions: In a real-world setting, HCL users gained more weight during pregnancy and had larger newborns than MDI users, while achieving similar glycemic control in terms of HbA1c and TIR.

Telehealth model versus in-person standard care for persons with type 1 diabetes treated with multiple daily injections: an open-label randomized controlled trial.

Objective: Increasing evidence indicates that the telehealth (TH) model is noninferior to the in-person approach regarding metabolic control in type 1 diabetes (T1D) and offers advantages such as a decrease in travel time and increased accessibility for shorter/frequent visits. The primary aim of this study was to compare the change in glycated hemoglobin (HbA1c) at 6 months in T1D care in a rural area between TH and in-person visits. Research design and methods: Randomized controlled, open-label, parallel-arm study among adults with T1D. Participants were submitted to in-person visits at baseline and at months 3 and 6 (conventional group) or teleconsultation in months 1 to 4 plus 2 in-person visits (baseline and 6 months) (TH group). Mixed effects models estimated differences in HbA1c changes. Results: Fifty-five participants were included (29 conventional/26 TH). No significant differences in HbA1c between groups were found. Significant improvement in time in range (5.40, 95% confidence interval (CI): 0.43-10.38; p < 0.05) and in time above range (-6.34, 95% CI: -12.13- -0.55;p < 0.05) in the TH group and an improvement in the Diabetes Quality of Life questionnaire (EsDQoL) score (-7.65, 95% CI: -14.67 - -0.63; p < 0.05) were observed. In TH, the costs for the participants were lower. Conclusions: The TH model is comparable to in-person visits regarding HbA1c levels at the 6-month follow-up, with significant improvement in some glucose metrics and health-related quality of life. Further studies are necessary to evaluate a more efficient timing of the TH visits.

Atherogenic dyslipidaemia in type 2 diabetes mellitus: The PREDISAT study.

Extremely variable prevalence rates of atherogenic dyslipidaemia (AD) in type 2 diabetes (T2DM) subjects have been reported. The primary aim was to assess AD prevalence in Spanish T2DM subjects. Secondary objectives were to evaluate the differential clinical characteristics between T2DM subjects with and without AD, to describe lipid profile evolution and use of lipid-lowering treatment in clinical practice by the Spanish Lipid Units. Data was obtained from the National Registry of Dyslipidaemias of the Spanish Atherosclerosis Society, from a multicentric sub-study focused on AD prevalence in T2DM subjects (PREDISAT study). The inclusion criteria were subjects diagnosed of T2DM with age ≥18 years old. A total of 385 T2DM subjects with a mean age of 61 years and 246 (64%) men were included. The mean follow-up was 22 ± 7.4 months. At baseline, 41.3% of the T2DM subjects presented AD, this percentage decreasing to 34.8% with therapeutic intervention. AD prevalence varied in different age groups and appeared to be more prevalent in younger T2DM subjects. Those with AD had a more atherogenic lipid profile at baseline, with higher total cholesterol, triglyceride and non-(high-density lipoprotein) HDL cholesterol levels at baseline, together with lower HDL cholesterol concentrations, without achieving lipid subfraction goals during follow-up. Although almost 90% of the AD subjects were under lipid-lowering treatment, most were receiving only one drug, being statins the most used treatmentA high AD prevalence in T2DM subjects was observed, being age a determinant factor, with a modest decline during follow-up. Although almost 90% of the AD subjects were under lipid-lowering drugs, most were only receiving monotherapy with statins.

Acute-to-Chronic Glycemic Ratio as a Predictor of COVID-19 Severity and Mortality.

OBJECTIVE: To evaluate the association between acute-to-chronic (A/C) glycemic ratio and mortality and severity outcomes for patients with type 2 diabetes (T2D) hospitalized with coronavirus disease 2019 (COVID-19). RESEARCH DESIGN AND METHODS: A total of 91 patients were included. We measured glycemia at admission and estimated the average chronic glucose levels to calculate the A/C glycemic ratio. The primary outcome was a composite of in-hospital mortality, intensive care unit admission, and mechanical ventilation. RESULTS: Thirty-five patients had a primary outcome event, presenting a significant association with the A/C glycemic ratio (hazard ratio [HR] 1.57 [95% CI 1.14-2.15], P = 0.005). In comparisons with the 2nd tertile, the 3rd tertile of the A/C glycemic ratio was associated with the primary outcome (HR 3.39 [95% CI 1.31-8.75], P = 0.012). In the multivariate analysis, after additional adjustment for age, sex, comorbidities, inflammatory markers, and corticosteroid therapy, the association for the 3rd tertile (HR 3.96 [95% CI 1.35-11.59], P = 0.012) remained significant. CONCLUSIONS: In patients with T2D hospitalized with COVID-19, the imbalance between acute glycemia at admission and chronic metabolic control is associated with worse prognosis.

Familial Hypercholesterolemia: Do HDL Play a Role?

Cardiovascular disease (CVD) in heterozygous familial hypercholesterolemia (HeFH), the most frequent monogenic disorder of human metabolism, is largely driven by low-density lipoprotein (LDL) cholesterol concentrations. Since the CVD rate differs considerably in this population, beyond the lifetime LDL cholesterol vascular accumulation, other classical risk factors are involved in the high cardiovascular risk of HeFH. Among other lipoprotein disturbances, alterations in the phenotype and functionality of high-density lipoproteins (HDL) have been described in HeFH patients, contributing to the presence and severity of CVD. In fact, HDL are the first defensive barrier against the burden of high LDL cholesterol levels owing to their contribution to reverse cholesterol transport as well as their antioxidant and anti-inflammatory properties, among others. In this context, the present narrative review aimed to focus on quantitative and qualitative abnormalities in HDL particles in HeFH, encompassing metabolic, genetic and epigenetic aspects.

Hydrophilic or Lipophilic Statins?

Drugs can be classified as hydrophilic or lipophilic depending on their ability to dissolve in water or in lipid-containing media. The predominantly lipophilic statins (simvastatin, fluvastatin, pitavastatin, lovastatin and atorvastatin) can easily enter cells, whereas hydrophilic statins (rosuvastatin and pravastatin) present greater hepatoselectivity. Although the beneficial role of statins in primary and secondary cardiovascular prevention has been unequivocally confirmed, the possible superiority of one statin or other regarding their solubility profile is still not well-established. In this respect, although some previously published observational studies and clinical trials observed a superiority of lipophilic statins in cardiovascular outcomes, these results could also be explained by a greater low-density lipoprotein cholesterol reduction with this statin type. On the other hand, previous studies reported conflicting results as to the possible superiority of one statin type over the other regarding heart failure outcomes. Furthermore, adverse events with statin therapy may also be related to their solubility profile. Thus, the aim of the present review was to collect clinical evidence on possible differences in cardiovascular outcomes among statins when their solubility profile is considered, and how this may also be related to the occurrence of statin-related adverse effects.

Bariatric Surgery and Hypertension.

A clear pathogenetic association exists between obesity and arterial hypertension, becoming even more evident in subjects with severe obesity. Bariatric surgery has proved to be the most effective treatment for severe obesity, with its benefits going beyond weight loss. The present review aimed to determine the effects of bariatric surgery on arterial hypertension evident in short- and long-term follow-ups. Moreover, the differences between surgical techniques regarding hypertension remission are described as well as the possible pathophysiologic mechanisms involved. In addition, the effects of bariatric surgery beyond blood pressure normalization are also analyzed, including those on target organs and cardiovascular morbidity and mortality.

Familial combined hyperlipidaemia/polygenic mixed hyperlipidaemia. / Hiperlipemia familiar combinada/hiperlipemia mixta poligénica.

Familial combined hyperlipidaemia (FCH) is the most prevalent form of familial hyperlipidaemia with a multigenic origin and a complex pattern of inheritance. In this respect, FCH is an oligogenic primary lipid disorder due to interaction of genetic variants and mutations with environmental factors. Patients with FCH are at increased risk of cardiovascular disease and often have other associated metabolic conditions. Despite its relevance in cardiovascular prevention, FCH is frequently underdiagnosed and very often undertreated. In this review, emphasis is placed on the most recent advances in FCH, in order to increase its awareness and ultimately contribute to improving its clinical control.

Prognostic Value of the Acute-to-Chronic Glycemic Ratio at Admission in Heart Failure: A Prospective Study.

Acute hyperglycemia has been associated with worse prognosis in patients hospitalized for heart failure (HF). Nevertheless, studies evaluating the impact of glycemic control on long-term prognosis have shown conflicting results. Our aim was to assess the relationship between acute-to-chronic (A/C) glycemic ratio and 4-year mortality in a cohort of subjects hospitalized for acute HF. A total of 1062 subjects were consecutively included. We measured glycaemia at admission and estimated average chronic glucose levels and the A/C glycemic ratio were calculated. Subjects were stratified into groups according to the A/C glycemic ratio tertiles. The primary endpoint was 4-year mortality. Subjects with diabetes had higher risk for mortality compared to those without (HR 1.35 [95% CI: 1.10-1.65]; p = 0.004). A U-shape curve association was found between glucose at admission and mortality, with a HR of 1.60 [95% CI: 1.22-2.11]; p = 0.001, and a HR of 1.29 [95% CI: 0.97-1.70]; p = 0.078 for the first and the third tertile, respectively, in subjects with diabetes. Additionally, the A/C glycemic ratio was negatively associated with mortality (HR 0.76 [95% CI: 0.58-0.99]; p = 0.046 and HR 0.68 [95% CI: 0.52-0.89]; p = 0.005 for the second and third tertile, respectively). In multivariable analysis, the A/C glycemic ratio remained an independent predictor. In conclusion, in subjects hospitalized for acute HF, the A/C glycemic ratio is significantly associated with mortality, improving the ability to predict mortality compared with glucose levels at admission or average chronic glucose concentrations, especially in subjects with diabetes.

Bariatric surgery improves metabolic and nonalcoholic fatty liver disease markers in metabolically healthy patients with morbid obesity at 5 years.

BACKGROUND: No studies have evaluated the effect of metabolic and bariatric surgery (MBS) on nonalcoholic fatty liver disease (NAFLD) and cardiometabolic markers in metabolically healthy patients with morbid obesity (MHMO) at midterm. OBJECTIVES: To assess the effect of MBS on NAFLD and cardiometabolic markers in MHMO patients and ascertain whether metabolically unhealthy patients with morbid obesity (MUMO) remain metabolically healthy at 5 years after MBS. SETTING: University hospital. METHODS: A total of 191 patients with a body mass index >40 kg/m2 and at least 5 years of follow-up were retrospectively analyzed. Lost to follow-up were 37.6% (151 of 401 patients). Patients were classified as MHMO if 1 or 0 of the cardiometabolic markers were present using the Wildman criteria. The degree of liver fibrosis was assessed using the NAFLD fibrosis score (NFS). RESULTS: Forty-one patients (21.5%) fulfilled the criteria for MHMO. They showed significant improvements in blood pressure (from 135.1 ± 22.1 and 84.2 ± 14.3 mm Hg to 117.7 ± 19.2 and 73.0 ± 10.9 mm Hg), plasma glucose (from 91.0 ± 5.6 mg/dL to 87.2 ± 5.2 mg/dL), homeostatic model assessment for insulin resistance (from 2.2 ± .9 to 1.0 ± .8), triglycerides (from 88.0 [range, 79.5-103.5] mg/dL to 61.0 [range, 2.0-76.5] mg/dL), alanine aminotransferase, gamma-glutamyl transpeptidase NFS (from -1.0 ± 1.0 to -1.9 ± 1.2), and high-density lipoprotein cholesterol (from 56.9 ± 10.5 mg/dL to 77.9 ± 17.4 mg/dL) at 5 years after surgery. A total of 108 MUMO patients (84.4%) who became metabolically healthy after 1 year stayed healthy at 5 years. CONCLUSIONS: MBS induced a midterm improvement in cardiometabolic and NAFLD markers in MHMO patients. Seventy-six percent of MUMO patients became metabolically healthy at 5 years after MBS.

Lipid-lowering treatment in secondary prevention of ischaemic cerebrovascular disease. / Tratamiento hipolipemiante en la prevención secundaria de la enfermedad cerebrovascular isquémica.

Stroke is the second cause of death after myocardial infarction, and the main cause of acquired disability. Patients with ischaemic stroke have a higher risk of future vascular events, including recurrent stroke, myocardial infarction, and death by vascular cause. The initial epidemiological studies demonstrated a weak or non-existent relationship between cholesterolaemia and stroke. Subsequently, statin intervention trials showed a reduction in the risk of recurrence of cerebrovascular events. The Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL), the first clinical trial designed to assess effects of statin therapy in secondary stroke prevention, highlighted the reduction of stroke recurrence with atorvastatin 80mg/daily in patients with a recent ischaemic established or transient stroke, with a modest increase in the rate of haemorrhagic stroke. Successive studies have also reported the benefits of statin therapy combined with ezetimibe or PCSK9 inhibitors in primary and secondary ischaemic stroke prevention. Since 80% of recurrent cerebrovascular events could be prevented, it is considered of interest to carry out a narrative review of the benefits of lipid-lowering therapy in the secondary prevention of ischaemic cerebrovascular disease.

Atherosclerosis and inflammation. New therapeutic approaches. / Arteriosclerosis e inflamación. Nuevos enfoques terapéuticos.

The recognition of atherogenesis as an active process rather than a passive cholesterol storage disease has underlined key inflammatory mechanisms. Hence, innate and adaptive immune responses play an important role in the onset and progression of atherosclerosis. More recently, some clinical studies were designed to address the impact of anti-inflammatory intervention strategies in reducing risk of cardiovascular disease beyond the management of classic risk factors. Therefore, we review first the pathophysiological contribution of inflammation to atherosclerosis and the effect of lipid-lowering drugs on inflammatory biomarkers. Next, we address the effect of classic anti-inflammatory drugs, pharmacological therapies targeting specific inflammatory mediators and vaccines in cardiovascular prevention.
