Influence of triglyceride concentration in lipoprotein (a) as a function of dyslipidemia. / Influencia de la concentración de triglicéridos en la lipoproteína(a) en función de la dislipidemia.

BACKGROUND: Recently, an inverse relationship between the blood concentration of lipoprotein(a) (Lp(a)) and triglycerides (TG) has been demonstrated. The larger the VLDL particle size, the greater the presence of VLDL rich in apoliprotein E and in subjects with the apoE2/E2 genotype, the lower Lp(a) concentration. The mechanism of this inverse association is unknown. The objective of this analysis was to evaluate the Lp(a)-TG association in patients treated at the lipid units included in the registry of the Spanish Society of Atherosclerosis (SEA) by comparing the different dyslipidemias. PATIENTS AND METHODS: Five thousand two hundred and seventy-five subjects ≥18 years of age registered in the registry before March 31, 2023, with Lp(a) concentration data and complete lipid profile information without treatment were included. RESULTS: The mean age was 53.0 ± 14.0 years, with 48% women. The 9.5% of subjects (n = 502) had diabetes and the 22.4% (n = 1184) were obese. The median TG level was 130 mg/dL (IQR 88.0-210) and Lp(a) 55.0 nmol/L (IQR 17.9-156). Lp(a) concentration showed a negative association with TG concentration when TG values exceeded 300 mg/dL. Subjects with TG > 1000 mg/dL showed the lowest level of Lp(a), 17.9 nmol/L, and subjects with TG < 300 mg/dL had a mean Lp(a) concentration of 60.1 nmol/L. In subjects without diabetes or obesity, the inverse association of Lp(a)-TG was especially important (p < 0.001). The median Lp(a) was 58.3 nmol/L in those with TG < 300 mg/dL and 22.0 nmol/L if TG > 1000 mg/dL. No association was found between TG and Lp(a) in subjects with diabetes and obesity, nor in subjects with familial hypercholesterolemia. In subjects with multifactorial combined hyperlipemia with TG < 300 mg/dL, Lp(a) was 64.6 nmol/L; in the range of 300-399 mg/dL of TG, Lp(a) decreased to 38. 8 nmol/L, and up to 22.3 nmol/L when TG > 1000 mg/dL. CONCLUSIONS: Our results show an inverse Lp(a)-TG relationship in TG concentrations > 300 mg/dL in subjects without diabetes, obesity and without familial hypercholesterolemia. Our results suggest that, in those hypertriglyceridemias due to hepatic overproduction of VLDL, the formation of Lp(a) is reduced, unlike those in which the peripheral catabolism of TG-rich lipoproteins is reduced.

Comprehensive Cardiovascular and Renal Protection in Patients with Type 2 Diabetes.

Type 2 diabetes (T2DM) is one of the main public health care problems worldwide. It is associated with a marked increased risk of developing atherosclerotic vascular disease, heart failure, chronic kidney disease and death. It is essential to act during the early phases of the disease, through the intensification of lifestyle changes and the prescription of those drugs that have been shown to reduce these complications, with the aim not only of achieving an adequate metabolic control, but also a comprehensive vascular risk control. In this consensus document, developed by the different specialists that treat these patients (endocrinologists, primary care physicians, internists, nephrologists and cardiologists), a more appropriate approach in the management of patients with T2DM or its complications is provided. A particular focus is given to the global control of cardiovascular risk factors, the inclusion of weight within the therapeutic objectives, the education of patients, the deprescription of those drugs without cardiovascular benefit, and the inclusion of GLP-1 receptor agonists and SGLT2 inhibitors as cardiovascular protective drugs, at the same level as statins, acetylsalicylic acid, or renin angiotensin system inhibitors.

Evolution and trends in referrals to a specialist gender identity unit in Spain over 10 years (2012-2021).

BACKGROUND: International studies have reported an increase in referrals to gender identity units, a shift in the assigned sex ratio of adolescents, a decrease in the age at first visit, and a growing presence of individuals with nonbinary gender identities. AIM: To investigate whether these trends are present in a Spanish sample of individuals referred to a gender identity unit over the last 10 years. METHODS: We conducted a retrospective chart review of 913 consecutive referrals to a gender identity unit between 2012 and 2021 and retrieved information regarding sex assigned at birth, age at first visit, and expressed gender identity. We stratified the patients into 5 age categories: children (<12 years), adolescents (12-17 years), young adults (18-25 years), adults (26-45 years), and older adults (>45 years). The data were analyzed via descriptive and regression analyses. OUTCOMES: Outcomes included the number of annual referrals, age at first visit, assigned sex ratio, and individuals with nonbinary gender identities. RESULTS: The number of referrals increased 10-fold, from 18 in 2012 to 189 in 2021. The rates of increase over time were significantly more pronounced for adolescents and young adults and significantly greater for those assigned female at birth (AFAB). The age of referrals at first visit decreased, and AFAB individuals were, on average, younger than individuals assigned male at birth. The assigned sex ratio favored AFAB patients among adolescents (2.4:1) and young adults (1.75:1). Logistic regression showed that the odds of a new referral being AFAB increased by 9% per calendar year and that adolescent and young adult new referrals were significantly more likely to be AFAB. There were 21 referrals of nonbinary individuals starting in 2017, making up 6.4% of applications in 2021 and 2.9% during the last 5 years. CLINICAL IMPLICATIONS: The evolution and trends observed in this study highlight the need for expanded resources, competent care, and careful reflection about implications for best practice. STRENGTHS AND LIMITATIONS: This investigation involves a large sample of patients and is the first in our country to include people of all ages. However, the findings might not be generalizable to other gender identity units or the broader population of gender-diverse individuals. CONCLUSION: Overall, our findings were consistent with previous international reports. We observed a marked increase in referrals, particularly among AFAB adolescents and young adults, a decreased age at first visit, and a growing presence of nonbinary individuals.

Medical detransition following transgender identity reaffirmation: two case reports.

Background Recently, increased social and scientific attention has been paid to gender detransition, a phenomenon in which individuals discontinue gender-affirming medical interventions (GAMI) aimed at alleviating gender dysphoria (GD). Yet, clinical knowledge of detransitioners and their experiences is still scarce. Case reports published in the literature suggest that both internal and external factors may influence this decision. Methods Two transgender individuals treated for GD at a gender identity unit presented with a desire to discontinue GAMI. A description of their clinical evolution is presented. Results Increased body satisfaction, self-esteem, self-acceptance, and self-empowerment with respect to their transgender identity were mentioned by the patients as reasons for discontinuing gender-affirming treatments. Coinciding factors included reduced GD, positive changes in social environments, better interpersonal functioning, and higher levels of psychological well-being in general. Conclusions Gender detransition is an under-researched phenomenon. These cases highlight the need for a more nuanced approach to gender-related clinical presentations, which involves providing individuals the opportunity to work on their social ecosystems and explore alternative options to manage GD before initiating GAMI.

Percutaneous ethanol injection therapy as the first line of treatment of symptomatic thyroid cysts.

BACKGROUND: Our aim was to evaluate the efficacy and security of ultrasound-guided percutaneous ethanol injection therapy (US-PEIT) for the treatment of recurrent symptomatic thyroid cysts in two high-resolution consultations of thyroid nodule in the Valencian Community. PATIENTS AND METHODS: The study comprised thirty-three consecutive patients (51 ±â€¯12 years, 76% women) with symptomatic benign thyroid cysts relapsed after drainage and benign cytology prior to treatment. Through ultrasound, maximum cyst diameter and volume were determined, and the content of the cyst was drained. We then instilled between 2 and 4 ml of ethanol (according to initial volume). We followed up with ultrasound at one, 3, 6 and 12 months and we calculated the total volume and the Volume Reduction Rate (VRR). We evaluated the perceived pain using a visual analog scale. RESULTS: The initial median cyst volume was 11.6 ml (8.5-16.5) A single session of US-PEIT was required in 22 patients (67%), two in 8 (24%) and three in 3 (9%). During PEIT, 49% of the patients experienced virtually no pain, 39% mild pain and 12% moderate pain. There were no complications. After 6 months of follow up the median VRR was 93% (84-98). All the patients achieved a volume reduction of more than 50%, 94% of more than 70% and 56% of more than 90%. Twenty-four patients completed a year of follow-up, achieving a VRR of 97% (93-98). CONCLUSIONS: In our experience US-PEIT has proven to be an effective, safe treatment of symptomatic thyroid cysts. For this reason it can be considered as the first line of treatment and included in the portfolio of services of a high-resolution consultation.

Self-injurious and suicidal behaviour in a transsexual adolescent and young adult population, treated at a specialised gender identity unit in Spain.

INTRODUCTION: Nonsuicidal self-injury (NSSI) and suicidal behavior (SB) have a significant prevalence in transsexual people. The published data is confusing as it does not distinguish between ideation and realization, age groups, gender, or the degree of medical intervention. Their actual prevalence in Spain is unknown. OBJECTIVE: Our objective was to investigate the prevalence of NSSI behavior and SB in adolescents and young transsexual adults, differentiating between ideation and consummated behavior, prior to their receiving any type of gender-affirming medical treatment. MATERIAL AND METHODS: We retrospectively reviewed the medical history of a cohort of transsexual people aged between 10 and 35 years, treated at the Gender Identity Unit of the Valencian Community. We analyzed the data collected regarding the presence of four variables: NSSI ideation, NSSI behavior, ideas of suicide and suicide attempts, as well as differences according to age group and gender. RESULTS: The final sample consisted of 110 transsexual men and 90 transsexual women. Of these, 21% had made a suicide attempt, 50% had had suicidal ideas, 31% had a history of NSSI behavior and 35% had had NSSI ideas. No differences were found based on gender. Regarding age, subjects under 20 years of age presented a significantly higher prevalence regarding suicidal ideas compared to young adults (43% vs. 25%), while in the remaining variables, no statistically significant differences were found. CONCLUSIONS: The prevalence of a history of suicidal ideas and behavior in the Spanish adolescent and young transsexual population is significant and does not differ according to gender or age range. The prevalence of NSSI ideas and behavior differs and is more frequent in adolescent transsexuals.

Secondary thoracolumbar deformity and sagittal imbalance due to osteoporosis in a young man with Cushing's disease: A case report.

INTRODUCTION: To describe an unusual case of Cushing's disease with spontaneous axial pain due to multiple consecutive vertebral fractures which led to secondary deformity that required surgical treatment. PRESENTATION OF CASE: A 43-year-old man was referred to our service with back pain without previous trauma. He was diagnosed of refractory arterial hypertension and we observed centripetal obesity during exploration. With clinical findings and laboratory studies, ACTH-dependent Cushing's syndrome due to a pituitary microadenoma was diagnosed and the patient underwent an endoscopic-assisted endonasal transsphenoidal resection. Dual energy X-ray absorptiometry (DXA) revealed spine and hip osteoporosis. Moreover, X-ray, MR and CT showed multiple vertebral osteoporotic compression fractures in thoracic and thoracolumbar area. Secondary kyphosis thoracolumbar deformity and sagittal imbalance was treated by two-level Smith-Petersen osteotomies (SPO) and instrumented posterolateral arthrodesis T10-L3 using fenestrated pedicles screws with polymethyl methacrylate (PMMA). At six years of follow-up dual energy X-ray absorptiometry (DXA) recovered normal values (T-score lumbar spine L2-L4 1.4 and T-score hip -1.9) and X-ray study showed an adequate sagittal vertebral axis. DISCUSSION: Osteoporosis is a common feature of CD and fractures occur in 30-50% of cases. Treating the underlying cause reduces the risk of new fractures. Medical therapy is usually enough but consecutive multiple vertebral fractures related to glucocorticoid excess may lead to secondary painful deformity. CONCLUSION: Vertebral compression fractures result from secondary corticoid-induced osteoporosis in Cushing's disease. Early detection and treatment of primary disease decreases the risk of new fractures. However, unusual secondary spinal deformity or disability may require surgery.

Transsexuality: Transitions, detransitions, and regrets in Spain. / Transexualidad: transiciones, detransiciones y arrepentimientos en España.

INTRODUCTION: Health care demand by transsexual people has recently increased, mostly at the expense of young and adolescents. The number of people who report a loss of or change in the former identity feeling (identity desistance) has also increased. While these are still a minority, we face more and more cases of transsexual people who ask for detransition and reversal of the changes achieved due to regret. OBJECTIVE: To report our experience with a group of transsexual people in detransition phase, and to analyze their personal experience and their associated conflicts. MATERIAL AND METHODS: A cohort of 796 people with gender incongruence attending the Identity Gender Unit of Doctor Peset University Hospital from January 2008 to December 2018 was studied. Four of the eight documented cases of detransition and/or regret are reported as the most representative. RESULTS: Causes of detransition included identity desistance, non-binary gender variants, associated psicomorbidities, and confusion between sexual identity and sexual orientation. CONCLUSION: Detransition is a growing phenomenon that implies clinical, psychological, and social issues. Inadequate evaluation and use of medicalization as the only means to improve gender dysphoria may lead to later detransition in some teenagers. Comprehensive care by a multidisciplinary and experienced team is essential. As there are no studies reporting the factors predictive of detransition, caution is recommended in cases of atypical identity courses.

Spanish population trends in Internet searches for information on different diets. / Tendencia de la población española de búsqueda en internet sobre información relacionada con diferentes dietas.

OBJECTIVE: To use Google Trends to explore the trends of interest of the Spanish population regarding information related to different types of diets, focused on those that are popular and with evidence-based studies, over the last 10years. MATERIAL AND METHODS: The search trends referred to the terms «Mediterranean diet¼, «ketogenic diet¼, «low fat diet¼, «intermittent fasting¼ and «vegan diet¼ were analyzed. The relative search volumes (RSV) of the terms were compared. The direction of the trend was studied using the Spearman's correlation coefficient (SC). RESULTS: «Mediterranean diet¼ was the most widely searched term, with a median RSV of 16 (interquartile range [IQR] 6; range 8-100), though it exhibited a decreasing chronological trend (SC=-0.216). It was followed by «ketogenic diet¼, with an RSV of 8 (IQR 9; range 1-57); «vegan diet¼, with an RSV of 4 (IQR 5; range 0-16); «intermittent fasting¼, with an RSV of 2 (IQR 5; range 0-27), and «low fat diet¼, with an RSV of 1.16 (IQR 0; range 0-2). The term with the best correlation over time was «intermittent fasting¼ (SC=0.96), followed by «ketogenic diet¼ (SC=0.91) and «vegan diet¼ (SC=0.85). CONCLUSIONS: In Spain, the interest of the population in information about the Mediterranean diet is greater than for other diets. However, in recent years there has been a progressive increase in interest (measured as RSV) in other diets such as the ketogenic diet, vegan diet or intermittent fasting, and there has been a decrease in interest in the Mediterranean diet. The low fat diet does not generate interest in the Spanish population.

Trends on Diabetes Mellitus's healthcare management in Spain 2007-2015.

AIMS: To analyze the trends on diabetes mellitus (DM) healthcare management in Spain. METHODS: Retrospective observational study between January 1st 2007 and 31th December 2015 with DM as the principal diagnosis. The main clinical outcome measures were all-cause, in-hospital mortality and 30-day readmissions. We also analyze three Prevention Quality Indicators (PQI) for DM. RESULTS: The number of hospitalization episodes decreased significantly as well as the frequentation rate and average length of stay (Incidence Rate Ratio [IRR] = 0.963, p < 0.001; 0.91, p < 0.001 and 0.986, p < 0.001, respectively). Crude in-hospital mortality and readmissions rates and risk-standardized in-hospital mortality rates (RSMR), however, remained stable (IRR = 0.988, p = 0.073; IRR = 1.003, p = 0.334 and IRR = 0.997, p = 0.116, respectively). A relevant variability in RSMR, both at hospital (Median Odds Ratio 1.49) and regional level, was found. High volume hospitals (≥105 DM discharges at year) showed better outcomes. High variability was also found in PQI indicators al regional level. CONCLUSION: The present analysis shows an improvement in hospitalizations related to DM in Spain in the period 2007-2015. There was also a decrease in the frequentation rate and in the average length of stay. These findings are probably explained by quality improvements in the healthcare management of the DM at the ambulatory level. However, there were important differences in the management of diabetic inpatients both at the hospital and the regional level.

Short- and Long-Term Effects of Weight Loss on the Complement Component C3 After Laparoscopic Gastric Bypass in Obese Patients.

BACKGROUND: The C3 complement component (C3c) is increasingly recognized as a cardiometabolic risk factor, but how it is affected after weight loss through gastric bypass is a question yet to be answered. METHODS: A total of 66 obese patients underwent laparoscopic gastric bypass. Anthropometric parameters, total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol (HDLc), low-density lipoprotein cholesterol (LDLc), glucose, insulin, HOMA-IR, liver enzymes, high-sensitivity C-reactive protein (hsCRP), and C3c levels were evaluated at baseline and at 1 and 5 years post-surgery. RESULTS: All anthropometric and biochemical parameters improved significantly after surgery, although a deterioration was detected with respect to the percentage of excess of weight loss, insulin, TC, LDLc, and lactate dehydrogenase 5 years post-surgery. Despite this, a remission rate of 84 % was observed in the presence of metabolic syndrome after 5 years follow-up. hsCRP and C3c were reduced significantly after surgery and maintained throughout the experimental period. In addition, C3c was correlated with BMI and insulin at all time points. The multivariate regression model, in which C3c was a dependent variable, revealed that aspartate aminotransferase and BMI were independent variables at baseline, alkaline phosphatase and insulin were independent at 1 year post-surgery, and insulin, BMI, and TC were independent at 5 years post-surgery. CONCLUSIONS: C3c may be a marker of the chronic inflammatory process underlying insulin resistance. Its association with BMI and liver enzymes supports a major role in metabolic activity, although future research is needed to clarify the nature of the molecular mechanisms involved and the physiological significance of these findings.

[Metabolic syndrome in patients with coronary heart disease. Results of using different diagnostic criteria]. / Síndrome metabólico en pacientes con cardiopatía isquémica. Resultados obtenidos con la utilización de diferentes criterios.

A unified definition of metabolic syndrome, considered a common feature of cardiovascular risk, is lacking. The aim of this study was to compare the prevalence of this syndrome in patients with ischemic heart disease using two diagnostic criteria: the European Group of Resistance to Insulin and the National Cholesterol Education Program. We designed an observational, cross-sectional study of the factors that make up metabolic syndrome in subjects diagnosed with coronary heart disease. A total of 169 patients aged 35 to 79 years were studied (129 men and 40 women). With the European group criterion the percentage of patients with metabolic syndrome was 43.7%, whereas the American group criterion yielded a prevalence of 40.8% (no significant difference). The prevalence of metabolic syndrome among patients with ischemic heart disease is high. The diagnostic criteria used are similar and do not differ significantly, although diagnostic concordance was only 50%.

[Prevalence of metabolic syndrome in patients with coronary heart disease]. / Prevalencia del síndrome metabólico entre pacientes con cardiopatía isquémica.

BACKGROUND AND OBJECTIVE: We aimed to know the prevalence of classical cardiovascular risk factors, hyperinsulinism, insulin resistance and metabolic syndrome (MS) in a population with coronary heart disease (CHD) as compared with a population without personal or familial history of cardiovascular risk factors. SUBJECTS AND METHOD: This was an observational and transversal study of cardiovascular risk factors making up the MS in an adult population. 367 subjects aged 35-79 years (268 men and 99 women) were studied; 185 had CHD (141 men and 44 women) and 182 (127 men and 55 women) were included as a control population. 82 individuals of the control group who had no MS components were selected for the calculation of parameters of hyperinsulinism and the HOMA (Homeostasis Model Assessment) index in order to evaluate the insulin resistance. RESULTS: As compared with the control group, patients with CHD showed higher blood pressure (systolic and dyastolic), body mass index (BMI), triglicerydes and apo B100 concentrations, and lower HDL-c and apo A1 values. They also exhibited higher values of glycemia and insulinemia and consequently a higher HOMA index. The values of insulin and HOMA (percentil 75), obtained from the selected group for this purpose, were 12 U/ml and 3.03, respectively. In the CHD population, 38.28% (95% CI, 31.13-45.95) had hyperinsulinism, 47.02% (95% CI, 39.70-54.47) had insulin resistance (HOMA) and 41.08% (95% CI, 33.98-48.55) had MS. CONCLUSIONS: There was a high prevalence of cardiovascular risk factors in the CHD population. Patients with CHD have higher hyperinsulinism and insulin resistance as well as a greater prevalence of MS. Despite treatment, a clear association exists between MS and CHD in both men and women.
