Effects of a HIIT Protocol on Cardiovascular Risk Factors in a Type 1 Diabetes Mellitus Population
2021
Cardiovascular complications are important causes of morbidity and mortality of Type 1 Diabetes Mellitus (T1DM) people. Regular exercise is strongly recommended to these patients due to its preventive action against this type of disease. However, a large percentage of patients with T1DM people present a sedentary behavior, mainly, because of the fear of a post-exercise hypoglycemia event and lack of time. High-intensity interval training (HIIT) is an efficient and safe methodology since it prevents hypoglycemia and does not require much time, which are the main barriers for this population to doing exercise and increasing physical conditioning. Nineteen sedentary adults (37 ± 6.5 years) wit…
Physical Activity, Incidence, and Progression of Age-Related Macular Degeneration: A Multicohort Study.
2022
Contains fulltext : 249581.pdf (Publisher’s version ) (Closed access) PURPOSE: To investigate the impact of physical activity (PA) on the incidence or progression of age-related macular degeneration (AMD) in the general population. DESIGN: Meta-analysis of longitudinal cohort studies. METHODS: We included 14,630 adults with no or early AMD at baseline from 7 population-based studies and examined associations of PA with AMD incidence and progression using multistate models (MSM) per study and subsequent random effects meta-analysis. Age effects were assessed using meta-regression. The main outcome measure was the hazard ratio (HR) for incident early or progression to late AMD. RESULTS: At ba…
Renal function and attributable risk of death and cardiovascular hospitalization in participants with diabetes from a registry-based cohort
2021
Abstract Aims To estimate the attributable risk of renal function on all-cause mortality and cardiovascular hospitalization in patients with diabetes. Methods A prospective cohort study in 19,469 adults with diabetes, free of cardiovascular disease, attending primary care in Spain (2008–2011). The estimated glomerular filtration rate (eGFR) and other variables were collected and patients were followed to the first hospitalization for coronary or stroke event, or death, until the end of 2012. The cumulative incidence of the study endpoints by eGFR categories was graphically displayed and adjusted population attributable risks (PARs) for low eGFR was calculated. Results Mean follow-up was 3.2…
Diagnostic radiological examinations and risk of intracranial tumours in adults—findings from the Interphone Study
2021
Abstract Background Exposure to high doses of ionizing radiation is among the few well-established brain tumour risk factors. We used data from the Interphone study to evaluate the effects of exposure to low-dose radiation from diagnostic radiological examinations on glioma, meningioma and acoustic neuroma risk. Methods Brain tumour cases (2644 gliomas, 2236 meningiomas, 1083 neuromas) diagnosed in 2000–02 were identified through hospitals in 13 countries, and 6068 controls (population-based controls in most centres) were included in the analysis. Participation across all centres was 64% for glioma cases, 78% for meningioma cases, 82% for acoustic neuroma cases and 53% for controls. Informa…
Risk of hypertension in women with polycystic ovary syndrome: a systematic review, meta-analysis and meta-regression
2019
Abstract Background A limited number of publications have assessed the prevalence of hypertension (HTN) in polycystic ovary syndrome (PCOS) patients with inconclusive results. Since in general populations the occurrence of hypertension is related to age per se, we investigated the prevalence (P) / relative risk (RR) of HTN in pooled patients with PCOS, vs control population among reproductive age women with PCOS, compared to menopause/aging patients. Methods PubMed, Scopus, ScienceDirect, web of science, and Google scholar were systematically searched for retrieving observational studies published from inception to April 2019 investigating the HTN in patients with PCOS. The primary outcome …
Factors Affecting Early Mortality and 1-Year Outcomes in Young Women With ST-Segment-Elevation Myocardial Infarction Aged Less Than or Equal to 45 Ye…
2018
Given that up to 2% of patients with myocardial infarction (MI) are young women, the purpose of this study was to evaluate factors affecting outcomes in young women with ST-segment-elevation myocardial infarction (STEMI) aged less than or equal to 45 years. We evaluated 796 women with STEMI aged less than or equal to 45 years between 2007 and 2014, and mortality was 4.0%. Death occurred more often in women with prehospital sudden cardiac arrest, and severe symptoms of heart failure; less commonly, the women were subjected to percutaneous coronary intervention (PCI), with a higher rate of incomplete revascularization. Beta blockers (BB) and angiotensin converting enzyme inhibitors were frequ…
Genetic polymorphisms of serotonin transporter and receptor 1A could influence success during embryo implantation and maintenance of pregnancy
2012
Objective To explore whether serotonin-related gene polymorphisms influence clinical outcomes of IVF treatment in recipients using donated oocytes. Design Nested case-control study. Setting University-affiliated infertility clinic. Patient(s) Two hundred forty-five women undergoing IVF treatment with donated oocytes. Intervention(s) None. Main Outcome Measure(s) Genotype and haplotype analysis of the serotonin transporter-linked polymorphic region (5-HTTLPR), rs1800532, rs6295, rs6313, and rs3813929, between recipients grouped according to the results of the oocyte donation for IVF treatment. Result(s) No differences were found between genotype distribution of the tryptophan hydroxylase 1, …
Coagulation, fibrinolysis and haemorheology in premenopausal obese women with different body fat distribution
1994
Recently waist/hip ratio (WHR), a marker of body fat distribution, has been described as a risk factor for cardiovascular disease (CVD). The aim of the present study was to evaluate the influence of body fat distribution on metabolic, haemostatic and haemorheological pattern in premenopausal obese women with different WHR. Fourty premenopausal obese women were subdivided into two groups, matched for age and body mass index (BMI): 20 women with abdominal obesity (WHR = 0.94 +/- 0.02) and 20 women with peripheral obesity (WHR = 0.77 +/- 0.03). Twenty nonobese women were recruited as control group. The abdominal obesity group had significantly higher blood glucose, triglycerides, total cholest…
Association between cardiorespiratory fitness and metabolic health in overweight and obese adults
2021
Background Cardiorespiratory fitness (CRF) has been inversely associated with insulin resistance and clustering of cardiometabolic risk factors among overweight and obese individuals. However, most previous studies have scaled CRF by body mass (BM) possibly inflating the association between CRF and cardiometabolic health. We investigated the associations of peak oxygen uptake (V O2peak) and peak power output (Wpeak) scaled either by BM-1, fat free mass (FFM-1), or by allometric methods with individual cardiometabolic risk factors and clustering of cardiometabolic risk factors in 55 overweight or obese adults with metabolic syndrome. Methods V O2peak and Wpeak were assessed by a maximal cycl…
Associations of maternal circulating 25-hydroxyvitamin D3 concentration with pregnancy and birth outcomes
2015
Objective To investigate the association of maternal circulating 25-hydroxyvitamin D3 [25(OH)D3] concentration with pregnancy and birth outcomes. Design Prospective cohort study. Setting Four geographical areas of Spain, 2003–2008. Population Of 2382 mother–child pairs participating in the INfancia y Medio Ambiente (INMA) Project. Methods Maternal circulating 25(OH)D3 concentration was measured in pregnancy (mean [SD] 13.5 [2.2] weeks of gestation). We tested associations of maternal 25(OH)D3 concentration with pregnancy and birth outcomes. Main outcome measures Gestational diabetes mellitus (GDM), preterm delivery, caesarean section, fetal growth restriction (FGR) and small-for-gestational…
