RESUMO
OBJECTIVE: This article aims to estimate the differences in environmental impact (greenhouse gas [GHG] emissions, land use, energy used, acidification and potential eutrophication) after one year of promoting a Mediterranean diet (MD). METHODS: Baseline and 1-year follow-up data from 5800 participants in the PREDIMED-Plus study were used. Each participant's food intake was estimated using validated semi-quantitative food frequency questionnaires, and the adherence to MD using the Dietary Score. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The association between MD adherence and its environmental impact was calculated using adjusted multivariate linear regression models. RESULTS: After one year of intervention, the kcal/day consumed was significantly reduced (-125,1 kcal/day), adherence to a MD pattern was improved (+0,9) and the environmental impact due to the diet was significantly reduced (GHG: -361 g/CO2-eq; Acidification:-11,5 g SO2-eq; Eutrophication:-4,7 g PO4-eq; Energy use:-842,7 kJ; and Land use:-2,2 m2). Higher adherence to MD (high vs. low) was significantly associated with lower environmental impact both at baseline and one year follow-up. Meat products had the greatest environmental impact in all the factors analysed, both at baseline and at one-year follow-up, in spite of the reduction observed in their consumption. CONCLUSIONS: A program promoting a MD, after one year of intervention, significantly reduced the environmental impact in all the factors analysed. Meat products had the greatest environmental impact in all the dimensions analysed.

OBJECTIVES: We tested the effects of a weight-loss intervention encouraging energy-reduced MedDiet and physical activity (PA) in comparison to ad libitum MedDiet on COVID-19 incidence in older adults. DESIGN: Secondary analysis of PREDIMED-Plus, a prospective, ongoing, multicentre randomized controlled trial. SETTING: Community-dwelling, free-living participants in PREDIMED-Plus trial. PARTICIPANTS: 6,874 Spanish older adults (55-75 years, 49% women) with overweight/obesity and metabolic syndrome. INTERVENTION: Participants were randomised to Intervention (IG) or Control (CG) Group. IG received intensive behavioural intervention for weight loss with an energy-reduced MedDiet intervention and PA promotion. CG was encouraged to consume ad libitum MedDiet without PA recommendations. MEASUREMENTS: COVID-19 was ascertained by an independent Event Committee until December 31, 2021. COX regression models compared the effect of PREDIMED-Plus interventions on COVID-19 risk. RESULTS: Overall, 653 COVID-19 incident cases were documented (IG:317; CG:336) over a median (IQR) follow-up of 5.8 (1.3) years (inclusive of 4.0 (1.2) years before community transmission of COVID-19) in both groups. A significantly lowered risk of COVID-19 incidence was not evident in IG, compared to CG (fully-adjusted HR (95% CI): 0.96 (0.81,1.12)). CONCLUSIONS: There was no evidence to show that an intensive weight-loss intervention encouraging energy-reduced MedDiet and PA significantly lowered COVID-19 risk in older adults with overweight/obesity and metabolic syndrome in comparison to ad libitum MedDiet. Recommendations to improve adherence to MedDiet provided with or without lifestyle modification suggestions for weight loss may have similar effects in protecting against COVID-19 risk in older adults with high cardiovascular risks.

BACKGROUND: Emerging evidence suggests that frailty may be a significant predictor of poor outcomes in older individuals hospitalized due to COVID-19. This study aims to determine the prognostic value of frailty on intrahospital patient survival. METHODS: This observational, multicenter, nationwide study included patients aged 70 years and older who were hospitalized due to COVID-19 in Spain between March 1 and December 31, 2020. Patient data were obtained from the SEMI-COVID-19 Registry of the Spanish Society of Internal Medicine. Frailty was assessed using the Clinical Frailty Scale. The primary outcome was hospital survival. Cox proportional hazards models were used to assess predictors of survival. RESULTS: A total of 1,878 participants (52% men and 48% women) were included, with 1,351 (71.9%) survivors and 527 (28.1%) non-survivors. The non-survivor group had higher mean age (83.5 vs. 81 years), comorbidities (6.3 vs. 5.3 points on the Charlson index), degree of dependency (26.8% vs. 12.4% severely dependent patients), and frailty (34.5% vs. 14.7% severely frail patients) compared to survivors. However, there were no differences in terms of sex. Our results demonstrate that a moderate-severe degree of frailty is the primary factor independently associated with shorter survival [HR 2.344 (1.437-3.823; p<0.001) for CFS 5-6 and 3.694 (2.155-6.330; p<0.001) for CFS 7-9]. CONCLUSION: Frailty is the main predictor of adverse outcomes in older patients with COVID-19. The utilization of tools such as the Clinical Frailty Scale is crucial for early detection in this population.

INTRODUCTION: Older patients are more likely to have cognitive dysfunction, and a great proportion of patients undergone surgical procedures are older adults. Postoperative cognitive dysfunction (POCD) has been shown as a consistent complication after major surgical procedures such as heart surgery. AIM: To determine the presence of long-term POCD in ≥65-year-old patients undergoing coronary artery bypass grafting and aortic valve replacement, and to establish related risk factors. METHODS: We prospectively and sequentially included 44 patients with coronary disease and aortic stenosis scheduled for heart surgery. Follow-up of all patients was standardized and a neurocognitive evaluation were performed preoperatively and at 1, 6 and 12 months after surgery. RESULTS: Patients experienced a significantly postoperative cognitive dysfunction (33.5%, 63.4% and 38.9% at 1, 6 and 12 months, respectively) from baseline (20.5%). Patient-associated aspects such as age (p<0.01), history of smoking (p<0.01), arterial hypertension (p=0.022), diabetes mellitus (p=0.024), heart failure (p=0.036) and preoperative cognitive dysfunction (p<0.01), and surgery-associated aspects such as EuroSCORE (p<0.01) and operation time (p<0.01) were identified as related risk factors. CONCLUSIONS: Older patients who underwent heart surgery had long-term POCD. Both patient- and surgery-related risk factors were established as related risk factors. These findings suggest that the prevalence of cognitive dysfunction after cardiac surgery in older patients could be related to a possible progression to dementia. In addition, many of the risk factors identified may be modifiable but in practice, these patients are not attended to for their possible cognitive impairment.

As the coronavirus-2019 disease (COVID-19) pandemic, caused by the infection with severe acute respiratory syndrome (SARS-CoV-2) coronavirus type 2, has progressed, persistent COVID-19 syndrome is an increasingly recognized problem on which a significant volume of medical literature is developing. Symptoms may be persistent or appear, after an asymptomatic period, weeks or months after the initial infection. The clinical picture is as markedly heterogeneous and multisystemic as in the acute phase, so multidisciplinary management is required. In addition, their appearance is not related to the severity of the initial infection, so they can affect both mild patients, even asymptomatic, and seriously ill patients who have required hospitalization. Although it can affect people of any age, it is more common in middle-aged women. The sequelae can generate a high impact on the quality of life, and in the work and social environment. The objective of this paper is to review persistent COVID-19 syndrome, to know its clinical manifestations and the strategies for the management and follow-up of these patients.

RESUMO
RATIONALE: CD36 is a scavenger receptor located on monocytes which is involved in foam cell transformation. AIM: To evaluate CD36 expression under different glycemic states in both healthy subjects and in atherosclerotic patients. SUBJECTS AND METHODS: In order to evaluate the possible effects of hyperglycemia on CD36 expression in healthy subjects, an in vitro experiment was carried out using monocyte in three different conditions: extreme hyperglycemia (HG), euglycemia (EG) and in the absence of glucose. On the other hand, three groups of atherosclerotic patients were evaluated according to their glycemic conditions: normoglycemic (NG), prediabetic (preDM) and diabetic (DM) patients. CD36 expression (mRNA, non-glycated and glycated protein) was analyzed in monocytes. RESULTS: CD36 mRNA expression in the in vitro experiment peaked at 4 and 24 h under HG conditions. No differences in mRNA levels were found in the EG and control group. The level of non-glycated proteins was higher in HG and EG conditions compared with control group. Glycated protein expression was inhibited by glucose in a sustained manner. In atherosclerotic patients, a significant association was observed when comparing glycated CD36 protein expression in DM with NG patients (p = 0.03). No significant differences were found in mRNA and non-glycated CD36 expression in these patients. Moreover, BMI, insulin, weight and treatment were shown to be related to CD36 expression (mRNA, non-glycated and glycated protein levels, depending of the case) in atherosclerotic patients. CONCLUSIONS: Hyperglycemia is an important modulator of CD36 mRNA and non-glycated protein expression in vitro, increasing de novo synthesis in healthy subjects. In atherosclerotic patients, there are progressive increases in CD36 receptors, which may be due to a post-translational stimulus.
RESUMO
BACKGROUND: The impact of a lifestyle intervention (LSI) program for the long-term management of subjects with metabolic syndrome in a primary care setting is not known. METHODS: This 3-year prospective controlled trial randomized adult subjects with metabolic syndrome to receive intensive LSI or to usual care in a community health centre in Malaga, Spain. LSI subjects received instruction on Mediterranean diet and a regular aerobic exercise program by their primary care professionals. Primary outcome included changes from baseline on different components of metabolic syndrome (abdominal circumference, blood pressure, HDL-cholesterol, fasting plasma glucose and triglycerides). RESULTS: Among the 2,492 subjects screened, 601 subjects with metabolic syndrome (24.1%) were randomized to LSI (n = 298) or to usual care (n = 303); of them, a 77% and a 58%, respectively, completed the study. At the end of the study period, LSI resulted in significant differences vs. usual care in abdominal circumference (-0.4 ± 6 cm vs. + 2.1 ± 6.7 cm, p < 0.001), systolic blood pressure (-5.5 ± 15 mmHg vs. -0.6 ± 19 mmHg, p = 0.004), diastolic blood pressure (-4.6 ± 10 mmHg vs. -0.2 ± 13 mmHg, p < 0.001) and HDL-cholesterol (+4 ± 12 mg/dL vs. + 2 ± 12 mg/dL, p = 0.05); however, there were no differences in fasting plasma glucose and triglyceride concentration (-4 ± 35 mg/dl vs. -1 ± 32 mg/dl, p = 0.43 and -0.4 ± 83 mg/dl vs. +6 ± 113 mg/dl, p = 0.28). CONCLUSION: Intensive LSI counseling provided by primary care professionals resulted in significant improvements in abdominal circumference, blood pressure and HDL-cholesterol but had limited effects on glucose and triglyceride levels in patients with metabolic syndrome.

BACKGROUND: The existence of seasonal variability in patients with acute pulmonary embolism (PE) has been debated for years, with contradictory results. The aim of this study was to identify the trend and possible existence of a seasonal pattern in hospitalizations for PE in Spain. METHODS: We analyzed the hospital discharge database of the Spanish National Health System from 2001 to 2010. Patients aged > 14 years diagnosed with PE were selected and a time series was constructed considering mean daily admissions for PE by month. The trend and seasonality factor of the series were determined using time-series analysis, and time-series modeling was used for analysis. Exponential smoothing models and the autoregressive integrated moving average test were used to generate a predictive model. RESULTS: From 2001 to 2010, there were 162,032 diagnoses of PE (5.07 per 1000 hospitalizations). In 105,168 cases, PE was the reason for admission. The PE diagnosis rate ranged from 4.14 per 1000 in 2001 to 6.56 per 1000 in 2010; and hospital admissions due to PE ranged from 2.67 to 4.28 per 1000 hospital discharges. Time-series analysis showed a linear increase in the incidence and a significant seasonal pattern with 17% more admissions in February and 12% fewer in June-July with respect to the central tendency (difference from February to June, 29%). CONCLUSIONS: The incidence of hospitalizations for PE showed a linear increase and a seasonal pattern, with the highest number of admissions in winter and the lowest number in summer.

In hospitalized diabetic patients, the recommended insulin therapy is basal bolus plus correction-dose regimen instead of sliding-scale insulin. The purpose of this study was to evaluate the effect of the implementation of a new protocol based on basal bolus therapy on managing diabetes in a university hospital setting. We performed a cross-sectional study before and 12 months after a 4-month intervention period to implement a basal bolus regimen in hospitalized patients. Non-critical patients admitted into the hospital for at least 72 h were included. Changes in prescribing habits, glucose control and incidence of hypoglycemia were evaluated. An increase in the use of the new protocol and a decrease in sliding scale were observed after the intervention. In the pre-intervention group, a total of 59.2% glucose readings were between 70 and 180 mg/dL versus 57.1% after the intervention, without observing statistical differences. Significant reductions in hypoglycemia between pre- and post-intervention (13.04 vs. 4.08%, p = 0.0215) were observed. The percentage of hospitalized diabetic patients who had HbA1c was 10.43 and 4.08% in pre- and post-intervention phases, respectively. The protocol showed beneficial outcomes in terms of fewer hypoglycemia episodes and reflected a change in prescription habits, but it did not improve glycemic control. Furthermore, the percentage of patients who had an HbA1c test during their hospitalization remained very low after the intervention. This fact may seriously limit the correct management of hyperglycemia after the hospital discharge.

Inflammatory markers are elevated in type 2 diabetic patients (DP) and may predict the development of type 2 diabetes. Our aims were to analyze differences in the expression of inflammatory and immunological molecules between DP and healthy subjects and to investigate whether glycemic control might prevent the overexpression of inflammatory markers in DP. Twenty-two DP with advanced atherosclerosis and eight healthy blood donors were included. DP were classified as well (HbA1c ≤ 6.5) or poorly controlled (HbA1c > 6.5). In "in vitro" studies, monocytes were exposed to low (5.5 mM) or high glucose (26 mM) concentrations in the absence or presence of insulin. Expression profiling of 14 inflammatory genes was analyzed using TLDA analysis. "In vivo" results show that monocytes from DP had increased levels of monocyte chemoattractant protein (MCP-1) and interleukin 6 (IL6) and lower levels of Toll-like receptor 2 (TLR2) mRNA than healthy subjects. Well-controlled DP had lower levels of IL-6 than poorly controlled DP, suggesting that glycemic control may prevent IL6 mRNA alterations associated with diabetes. "In vitro" results demonstrate that glucose directly and significantly induced MCP-1 and IL6 and reduced TLR2 mRNA expression. Insulin at high dose (100 IU/ml) dramatically enhanced the upregulatory effects of glucose on MCP-1 and IL-6 and reduced per se TLR2 mRNA expression. MCP-1, IL-6 and TLR2 are key inflammatory players altered in monocytes from type 2 DP. Both hyperinsulinemia and hyperglycemia contribute to alter the expression of these genes. The glycemic control only significantly prevented IL6 overexpression in this group of patients.

AIMS: To analyse the differences in the prevalence of diabetes and dysglycaemia using fasting plasma glucose and HbA(1c) criteria. METHODS: Analytical cross-sectional study undertaken in a random sample of 2144 individuals (age 18-80 years) without known diabetes from the primary care setting in Malaga (Spain). Dysglycaemia was defined as fasting plasma glucose 5.6-6.9 mmol/l or HbA(1c) 39-46 mmol/mol (5.7-6.4%) and diabetes as fasting plasma glucose ≥ 7.0 mmol/l or HbA(1c)≥ 48 mmol/mol (≥ 6.5%). RESULTS: The proportion of subjects who were normoglycaemic was significantly higher using fasting plasma glucose than HbA(1c) (83.5 vs. 65%) (P < 0.0001). Compared with fasting plasma glucose, HbA(1c) detects more cases of dysglycaemia (32 vs. 14.8%) (P < 0.0001) and diabetes (3 vs. 1.7%) (P < 0.0001). CONCLUSIONS: In our environment, using HbA(1c) for the diagnosis of pre-diabetes and diabetes could increase the target population for preventive and therapeutic measures. Further cost-effectiveness studies are needed before the widespread diagnostic use of HbA(1c) can be recommended.

AIMS: To study the prevalence of cardiovascular risk factors in an urban population of Malaga, Spain and its relationship with educational level. METHODS: A cross-sectional study was performed with a random representative sample of 2270 individuals from the adult population (1880 years) from a specific Health-Care Centre in Malaga City. All participants underwent a clinical interview, including social-demographical information and a physical examination. A blood sample was also drawn. RESULTS: The mean age of the participants was 43.6 ± 15.6 years and 57.6% had a low educational level. The prevalence of cardiovascular risk factors was: smoking 27.7%, hypertension 33.1%, diabetes 7.1% and dyslipidaemia 65.4%. Over 60% were either overweight or obese, and 76.7% had a sedentary lifestyle. Except for smoking and a low-HDL cholesterol, the prevalence of the other cardiovascular risk factors increased with age. A low educational level was associated with a high prevalence of cardiovascular risk factors, and this association was significant with regard to smoking, obesity, abdominal obesity and hypertriglyceridaemia. CONCLUSIONS: The population studied presents a high prevalence of cardiovascular risk factors, especially dyslipidaemia and obesity. The low academic level was associated with an increased prevalence of smoking, obesity and dyslipidaemia. People with a low socio-cultural level are a priority target for introducing policies to prevent and control cardiovascular disease.

AIM: To study the prevalence of hypertriglyceridemic waist (HTGW) in an urban adult Spanish population and its association with type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). METHODS: We undertook a cross-sectional analysis in a random sample of 2270 individuals (18-80 years of age). All participants provided a clinical history and underwent a physical examination. Blood and urine analyses were conducted. HTGW was diagnosed using anthropometric criteria for the European population (waist circumference: for men, ≥ 94 cm; for women, ≥ 80 cm) and fasting plasma triglycerides (TGs) ≥ 1.71 mmol l(-1) (≥ 150 mg per 100 ml). RESULTS: The prevalence of HTGW was 14.5% (men: 18.2%, women: 10.8%) and was significantly greater in men <59 years (P<0.001). HTGW was associated with older individuals, a low educational level and, in men, with a sedentary lifestyle (P<0.001). Subjects with HTGW had higher levels of total cholesterol, low-density lipoprotein-cholesterol (LDL-c) and uric acid, lower levels of high-density lipoprotein-cholesterol, a higher blood pressure, a greater degree of obesity and a higher prevalence of T2DM (20.00 vs 6.4%, P<0.001) (odds ratio (OR) 3.61; 95% confidence interval (95% CI), 2.60-5.01) and CVD (8.5 vs 3.4%, P<0.001) (OR 2.63; 95% CI, 1.66-4.16). The association of HTGW with T2DM and CVD disappeared after adjusting for age. The degree of concordance between HTGW and the metabolic syndrome (MS) was moderate, with both the Adult Treatment Panel III Report (ATP-III) and the International Diabetes Federation criteria (κ=0.51 and κ=0.58, respectively). Subjects with isolated HTGW as compared with those with isolated MS (ATP-III) were younger, had greater levels of total cholesterol, LDL-c and TGs and a lower prevalence of obesity, high blood pressure and dysglycemia. CONCLUSION: HTGW is a phenotype of cardiometabolic risk prevalent in the adult population in our environment. HTGW may be an alternative to MS to detect the population at risk for T2DM and CVD, especially in young individuals who do not fulfill the criteria for MS.
