RESUMEN

BACKGROUND: Characteristics and prognosis of patients admitted with strong suspicion of myocardial infarction (MI) but discharged without an MI diagnosis are not well-described. OBJECTIVES: To compare background characteristics and cardiovascular outcomes in patients discharged with or without MI diagnosis. METHODS: The DETermination of the role of Oxygen in suspected Acute Myocardial Infarction (DETO2X-AMI) trial compared 6629 patients with strong suspicion of MI randomized to oxygen or ambient air. The main composite end-point of this subgroup analysis was the incidence of all-cause death, rehospitalization with MI, heart failure (HF) or stroke during a follow-up of 2.1 years (median; range: 1-3.7 years) irrespective of randomized treatment. RESULTS: 1619 (24%) received a non-MI discharge diagnosis, and 5010 patients (76%) were diagnosed with MI. Groups were similar in age, but non-MI patients were more commonly female and had more comorbidities. At thirty days, the incidence of the composite end-point was 2.8% (45 of 1619) in non-MI patients, compared to 5.0% (250 of 5010) in MI patients with lower incidences in all individual end-points. However, for the long-term follow-up, the incidence of the composite end-point increased in the non-MI patients to 17.7% (286 of 1619) as compared to 16.0% (804 of 5010) in MI patients, mainly driven by a higher incidence of all-cause death, stroke and HF. CONCLUSIONS: Patients admitted with a strong suspicion of MI but discharged with another diagnosis had more favourable outcomes in the short-term perspective, but from one year onwards, cardiovascular outcomes and death deteriorated to a worse long-term prognosis.

RESUMEN

The World Health Organization has issued international instructions for certification and classification (coding) of the coronavirus disease (COVID-19) as cause of death. Central to these instructions is the selection of the underlying cause of death for a public health preventive purpose. This article focuses on two rules for this selection: (1) that a death due to COVID-19 should be counted independently of pre-existing conditions that are suspected of triggering a severe course of COVID-19 and (2) that COVID-19 should not be considered as due to anything else. The article argues that observance of the first rule may not always lead to an optimal selection from a preventive point of view and that in the future the ascertainment of an animal source of the coronavirus (SARS-CoV-2) would make it possible to reconceptualize 'COVID-19' and create a zoonotic classification code by means of which a factor of a greater preventive value could be selected than what is currently possible.

RESUMEN

BACKGROUND: Patients with chronic kidney disease (CKD) have poor outcomes following myocardial infarction (MI). We performed an untargeted examination of 175 biomarkers to identify those with the strongest association with CKD and to examine the association of those biomarkers with long-term outcomes. METHODS: A total of 175 different biomarkers from MI patients enrolled in the Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) registry were analysed either by a multiple reaction monitoring mass spectrometry assay or by a multiplex assay (proximity extension assay). Random forests statistical models were used to assess the predictor importance of biomarkers, CKD and outcomes. RESULTS: A total of 1098 MI patients with a median estimated glomerular filtration rate of 85 mL min-1 /1.73 m2 were followed for a median of 3.2 years. The random forests analyses, without and with adjustment for differences in demography, comorbidities and severity of disease, identified six biomarkers (adrenomedullin, TNF receptor-1, adipocyte fatty acid-binding protein-4, TNF-related apoptosis-inducing ligand receptor 2, growth differentiation factor-15 and TNF receptor-2) to be strongly associated with CKD. All six biomarkers were also amongst the 15 strongest predictors for death, and four of them were amongst the strongest predictors of subsequent MI and heart failure hospitalization. CONCLUSION: In patients with MI, a proteomic approach could identify six biomarkers that best predicted CKD. These biomarkers were also amongst the most important predictors of long-term outcomes. Thus, these biomarkers indicate underlying mechanisms that may contribute to the poor prognosis seen in patients with MI and CKD.

RESUMEN

BACKGROUND: Myocardial infarction (MI) with nonobstructive coronary arteries (MINOCA) is receiving increasing interest as a prognostically adverse entity distinct from myocardial infarction with significant coronary artery disease (MI-CAD). However, data are still limited regarding long-term cardiovascular morbidity and cause-specific mortality in MINOCA. METHODS: This is a registry-based cohort study using data from patients admitted to Swedish coronary care units. We investigated various nonfatal outcomes (recurrent MI, hospitalization for heart failure or stroke) and fatal outcomes (cardiovascular, respiratory or cancer-related mortality) in 4069 patients without apparent acute cardiovascular disease, used as non-MI controls, 7266 patients with first-time MINOCA and 69 267 patients with first-time MI-CAD. RESULTS: Almost all event rates (median follow-up 3.8 years) increased in a stepwise fashion across the three cohorts [rates of major adverse events (MAE; composite of all-cause mortality, recurrent MI, hospitalization for heart failure or stroke): n = 268 (6.6%), n = 1563 (21.5%), n = 17 777 (25.7%), respectively]. Compared to non-MI controls, MINOCA patients had an adjusted hazard ratio (HR) of 2.12 (95% confidence interval 1.84-2.43) regarding MAE. MINOCA patients had a substantial risk of cardiovascular mortality and the highest numerical risks of respiratory and cancer-related mortality. Male sex, previous heart failure and chronic obstructive pulmonary disease had a stronger prognostic impact in MINOCA than in MI-CAD. Female MINOCA patients with atrial fibrillation were at particular risk. CONCLUSIONS: Patients with first-time MINOCA have a considerable risk of adverse events. This stresses the need for a comprehensive search of the cause of MINOCA, thorough treatment of underlying disease triggers and close follow-up.

RESUMEN

BACKGROUND: Cardiac troponin (cTn) levels reflect infarct size and depressed left ventricular ejection fraction (LVEF) in patients with non-ST elevation acute coronary syndrome (NSTE-ACS). However, there is very limited information on whether cTn measured with a high-sensitivity (hs) assay would provide incremental prognostic information to the LVEF in NSTE-ACS patients. METHODS: This was a registry-based study (SWEDEHEART registry) investigating 20,652 NSTE-ACS patients with available information on hs-cTnT (highest level recorded during the hospitalization) and the LVEF estimated using echocardiography. All patients had been followed for 1 year. RESULTS: Hs-cTnT levels independently predicted major cardiovascular events (MACE) in cohorts with normal, slightly depressed, moderately depressed, and severely depressed LVEF. The adjusted hazard ratios in these cohorts were 1.18 (95% CI 1.13-1.23), 1.12 (95% CI 1.06-1.18), 1.12 (95% CI 1.06-1.19), and 1.21 (95% CI 1.13-1.30), respectively. Hs-cTnT levels were particularly predictive for cardiovascular mortality and readmission for heart failure. Excluding patients with previous cardiac disease did not affect the overall interrelations of hs-cTnT and LVEF with MACE. CONCLUSIONS: Hs-cTnT levels provide incremental prognostic value independent of the LVEF in patients with NSTE-ACS. Hs-cTnT is particularly predictive for MACE in patients with severely depressed LVEF but also in those with a normal LVEF. Accordingly, a normal LVEF should not be used as an argument not to target patients to thorough workup.

RESUMEN

PURPOSE OF REVIEW: Cardiac troponin (cTn) plays an essential role for assessment of outcome in acute coronary syndrome (ACS). However, the prognostic value of cTn is not absolute. In this mini-review, we summarize the evidence on the utility of established biomarkers of left-ventricular dysfunction, hemodynamic stress, inflammation, and renal dysfunction for risk prediction beyond cTn in ACS. RECENT FINDINGS: Only few biomarkers consistently demonstrate additive prognostic value to cTn levels. The B-type natriuretic peptides (NPs) and growth-differentiation factor-15 (GDF-15) are most promising in this regard. However, there are uncertainties regarding the role of these biomarkers for guidance of treatment decisions, and their prognostic increment to cTn levels measured with high-sensitivity assays is largely unknown. The NPs and GDF-15 provide the strongest prognostic increment to cTn levels in ACS. However, the role of these biomarkers for clinical decision-making in contemporary settings has still to be defined.

RESUMEN

BACKGROUND/OBJECTIVES: Our objective was to investigate changes in liver fat and insulin sensitivity during a 2-year diet intervention. An ad libitum Paleolithic diet (PD) was compared with a conventional low-fat diet (LFD). SUBJECTS/METHODS: Seventy healthy, obese, postmenopausal women were randomized to either a PD or a conventional LFD. Diet intakes were ad libitum. Liver fat was measured with proton magnetic resonance spectroscopy. Insulin sensitivity was evaluated with oral glucose tolerance tests and calculated as homeostasis model assessment-insulin resistance (HOMA-IR)/liver insulin resistance (Liver IR) index for hepatic insulin sensitivity and oral glucose insulin sensitivity (OGIS)/Matsuda for peripheral insulin sensitivity. All measurements were performed at 0, 6 and 24 months. Forty-one women completed the examinations for liver fat and were included. RESULTS: Liver fat decreased after 6 months by 64% (95% confidence interval: 54-74%) in the PD group and by 43% (27-59%) in the LFD group (P<0.01 for difference between groups). After 24 months, liver fat decreased 50% (25-75%) in the PD group and 49% (27-71%) in the LFD group. Weight reduction between baseline and 6 months was correlated to liver fat improvement in the LFD group (rs=0.66, P<0.01) but not in the PD group (rs=0.07, P=0.75). Hepatic insulin sensitivity improved during the first 6 months in the PD group (P<0.001 for Liver IR index and HOMA-IR), but deteriorated between 6 and 24 months without association with liver fat changes. CONCLUSIONS: A PD with ad libitum intake had a significant and persistent effect on liver fat and differed significantly from a conventional LFD at 6 months. This difference may be due to food quality, for example, a higher content of mono- and polyunsaturated fatty acids in the PD. Changes in liver fat did not associate with alterations in insulin sensitivity.

RESUMEN

OBJECTIVES: The aim of this study was to explore the impact of severe mental illness (SMI) on myocardial infarction survival and determine the influence of risk factor burden, myocardial infarction severity and different treatments. DESIGN, SETTING AND PARTICIPANTS: This population-based cohort study, conducted in Sweden during the period 1997-2010, included all patients with a first diagnosis of myocardial infarction in the Swedish nationwide myocardial infarction register SWEDEHEART (n = 209 592). Exposure was defined as a diagnosis of SMI (i.e. bipolar disorder or schizophrenia) in the national patient register prior to infarction. Bias-minimized logistic regression models were identified using directed acyclic graphs and included covariates age, gender, smoking, diabetes, previous cardiovascular disease, myocardial infarction characteristics and treatment. MAIN OUTCOME MEASURES: The outcomes were 30-day and 1-year mortality, obtained through linkage with national population registers. RESULTS: Patients with bipolar disorder (n = 442) and schizophrenia (n = 541) were younger (mean age 68 and 63 years, respectively) than those without SMI (n = 208 609; mean age 71 years). The overall 30-day and 1-year mortality rates were 10% and 18%, respectively. Compared with patients without SMI, patients with SMI had higher 30-day [odds ratio (OR) 1.99, 95% confidence interval (CI) 1.55-2.56] and 1-year mortality (OR 2.11, 95% CI 1.74-2.56) in the fully adjusted model. The highest mortality was observed amongst patients with schizophrenia (30-day mortality: OR 2.58, 95% CI 1.88-3.54; 1-year mortality: OR 2.55, 95% CI 1.98-3.29). CONCLUSION: SMI is associated with a markedly higher mortality after myocardial infarction, also after accounting for contributing factors. It is imperative to identify the reasons for this higher mortality.

RESUMEN

BACKGROUND AND OBJECTIVES: In the past two decades, an increasing number of nationwide, Swedish Healthcare Quality Registries (QRs) focusing on specific disorders have been initiated, mostly by physicians. Here, we describe the purpose, organization, variables, coverage and completeness of 103 Swedish QRs. METHODS: From March to September 2013, we examined the 2012 applications of 103 QRs to the Swedish Association of Local Authorities and Regions (SALAR) and also studied the annual reports from the same QRs. After initial data abstraction, the coordinator of each QR was contacted at least twice between June and October 2013 and asked to confirm the accuracy of the data retrieved from the applications and reports. RESULTS: About 60% of the QRs covered ≥80% of their target population (completeness). Data recorded in Swedish QRs include aspects of disease management (diagnosis, clinical characteristics, treatment and lead times). In addition, some QRs retrieve data on self-reported quality of life (EQ5D, SF-36 and disease-specific measures), lifestyle (smoking) and general health status (World Health Organization performance status, body mass index and blood pressure). CONCLUSION: Detailed clinical data available in Swedish QRs complement information from government-administered registries and provide an important source not only for assessment and development of quality of care but also for research.

RESUMEN

BACKGROUND/OBJECTIVES: Tissue-specific glucocorticoid metabolism is altered in obesity, and may increase cardiovascular risk. This dysregulation is normalized by short-term calorie restriction and weight loss, an effect that varies with dietary macronutrient composition. However, tissue-specific glucocorticoid metabolism has not been studied during long-term (>6 months) dietary interventions. Therefore our aim was to test whether long-term dietary interventions, either a paleolithic-type diet (PD) or a diet according to Nordic nutrition recommendations (NNR) could normalize tissue-specific glucocorticoid metabolism in overweight and obese women. SUBJECTS/METHODS: Forty-nine overweight/obese postmenopausal women were randomized to a paleolithic diet or a diet according to NNR for 24 months. At baseline, 6 and 24 months anthropometric measurements, insulin sensitivity, excretion of urinary glucocorticoid metabolites in 24-hour collections, conversion of orally administered cortisone to plasma cortisol and transcript levels of 11ß hydroxysteroid dehydrogenase type 1 (11ßHSD1) in subcutaneous adipose tissue were studied. RESULTS: Both diet groups achieved significant and sustained weight loss. Weight loss with the PD was greater than on NNR diet after 6 months (P<0.001) but similar at 24 months. Urinary measurement of 5α-reductase activity was increased after 24 months in both groups compared with baseline (P<0.001). Subcutaneous adipose tissue 11ßHSD1 gene expression decreased at 6 and 24 months in both diet groups (P=0.036). Consistent with increased liver 11ßHSD1, conversion of oral cortisone to cortisol increased at 6 months (P=0.023) but was unchanged compared with baseline by 24 months. CONCLUSIONS: Long-term weight loss in postmenopausal women has tissue-specific and time-dependent effects on glucocorticoid metabolism. This may alter local-tissue cortisol exposure contributing to improved metabolic function during weight loss.

RESUMEN

OBJECTIVES: Ectopic fat accumulation in liver and skeletal muscle may be an essential link between abdominal obesity, insulin resistance and increased risk of cardiovascular disease after menopause. We hypothesized that a diet containing a relatively high content of protein and unsaturated fat [mainly monounsaturated fatty acids (MUFAs)] but limited carbohydrates and saturated fat would reduce lipid content in liver and muscle and increase insulin sensitivity in postmenopausal women. SUBJECTS: Ten healthy, nonsmoking postmenopausal women with a body mass index (BMI) >27 (28-35) kg m(-2) were included in the study. INTERVENTIONS: Participants were instructed to consume an ad libitum Palaeolithic-type diet intended to provide approximately 30 energy percentage (E%) protein, 40 E% fat (mainly MUFAs) and 30 E% carbohydrate. Intramyocellular lipid (IMCL) levels in calf muscles and liver triglyceride levels were quantified using proton magnetic resonance spectroscopy ((1) H-MRS) before and 5 weeks after dietary intervention. Insulin sensitivity was estimated by homoeostasis model assessment (HOMA) indices and the euglycaemic hyperinsulinaemic clamp technique. RESULTS: Mean energy intake decreased by 25% with a weight loss of 4.5 kg. BMI, waist and hip circumference, waist/hip ratio and abdominal sagittal diameter also decreased significantly, as did diastolic blood pressure (mean -7 mmHg), levels of fasting serum glucose, cholesterol, triglycerides, LDL/HDL cholesterol, apolipoprotein B (ApoB) and apolipoprotein A1 (ApoA1), urinary C-peptide and HOMA indices. Whole-body insulin sensitivity did not change. Liver triglyceride levels decreased by 49%, whereas IMCL levels in skeletal muscle were not significantly altered. CONCLUSIONS: A modified Palaeolithic-type diet has strong and tissue-specific effects on ectopic lipid deposition in postmenopausal women.

RESUMEN

Despite poor prognosis, patients with type 2 myocardial infarction (MI) tend to be underdiagnosed and undertreated compared to those with type 1 MI. Whether this discrepancy has improved over time is uncertain. We conducted a registry-based cohort study investigating type 2 MI patients managed at Swedish coronary care units (n = 14,833) during 2010-2022. Multivariable-adjusted changes (first three vs last three calendar years of the observation period) were assessed regarding diagnostic examinations (echocardiography, coronary assessment), provision of cardioprotective medications (betablockers, renin-angiotensin-aldosterone-system inhibitors, statins) and 1-year all-cause mortality. Compared to type 1 MI patients (n = 184,329), those with type 2 MI less often had diagnostic examinations and cardioprotective medications. Increases in the use of echocardiography (OR 1.08 [95% confidence interval 1.06-1.09]) and coronary assessment (OR 1.06 [95% confidence interval 1.04-1.08]) were smaller compared to type 1 MI (pinteraction < 0.001). The provision of medications did not increase in type 2 MI. All-cause mortality rate in type 2 MI was 25.4% without temporal change (OR 1.03 [95% confidence interval 0.98-1.07]). Taken together, the provision of medications and all-cause mortality did ot improve in type 2 MI despite modest increases in diagnostic procedures. This emphasizes the need of defining optimal care pathways in these patients.

RESUMEN

BACKGROUND: While the clinical importance of cardiac troponin is well-known in type 1 myocardial infarction (MI), evidence on this topic in type 2 MI is limited. We assessed the clinical and prognostic implications of high-sensitivity cardiac troponin (hs-cTnT) concentrations in a large sample of patients with type 2 MI. METHODS: Retrospective registry-based cohort study (SWEDEHEART) including 4607 patients with type 2 MI and 43,405 patients with type 1 MI, used for comparisons. Patients with ST-elevation MI were excluded. Multivariable-adjusted regressions were applied to investigate the associations of hs-cTnT concentrations (highest measured value during each hospitalization) with clinical variables and prognosis during a median follow-up of up to 1.9 years. RESULTS: Hs-cTnT concentrations (median 264 [25th, 75th percentiles 112-654] ng/L) were significantly associated with various cardiovascular risk factors and comorbidities in type 2 non-ST elevation MI (NSTEMI) but only weakly with the underlying triggering condition. Most of these findings including the magnitude of hs-cTn release were similar to type 1 NSTEMI. Hs-cTnT (ln) independently predicted all-cause mortality (hazard ratio 1.13 [95% confidence interval 1.09-1.17]) and major adverse events (hazard ratio 1.13 [95% confidence interval 1.10-1.17]) in type 2 NSTEMI, similar as for type 1 NSTEMI according to interaction analysis. The associations of hs-cTnT (ln) with poor prognosis tended to be stronger in type 2 NSTEMI patients without known cardiovascular disease. CONCLUSIONS: Hs-cTnT concentrations independently predict adverse outcome in type 2 NSTEMI. The similarities to type 1 NSTEMI however, are striking and emphasize the difficulty to distinguish both MI types.

RESUMEN

Despite improvements in the treatment of myocardial infarction (MI), risk-associated management disparities may exist. We investigated this issue including temporal trends in a large MI cohort (n = 179,291) registered 2005-2017 in SWEDEHEART. Multivariable models were used to study the associations between risk categories according to the GRACE 2.0 score and coronary procedures (timely reperfusion, invasive assessment ≤ 3 days, in-hospital coronary revascularization), pharmacological treatments (P2Y12-blockers, betablockers, renin-angiotensin-aldosterone-system [RAAS]-inhibitors, statins), structured follow-up and secondary prevention (smoking cessation, physical exercise training). High-risk patients (n = 76,295 [42.6%]) experienced less frequent medical interventions compared to low/intermediate-risk patients apart from betablocker treatment. Overall, intervention rates increased over time with more pronounced increases seen in high-risk patients compared to lower-risk patients for in-hospital coronary revascularization (+ 23.6% vs. + 12.5% in patients < 80 years) and medication with P2Y12-blockers (+ 22.2% vs. + 7.8%). However, less pronounced temporal increases were noted in high-risk patients for medication with RAAS-blockers (+ 8.5% vs. + 13.0%) and structured follow-up (+ 31.6% vs. + 36.3%); pinteraction < 0.001 for all. In conclusion, management of high-risk patients with MI is improving. However, the lower rates of follow-up and of RAAS-inhibitor prescription are a concern. Our data emphasize the need of continuous quality improvement initiatives.

RESUMEN

BACKGROUND AND AIM: In northern Sweden, consumption of both filtered and boiled coffee is common. Boiled coffee, especially popular in rural areas, is known to raise blood lipids, a risk factor for acute myocardial infarction (MI). To our knowledge, only one epidemiological study, a case-control study from Sweden, has investigated boiled coffee in MI, noting an increased risk at high consumption levels in men, and no association in women. The aim of the present nested case-referent study was to relate consumption of filtered and boiled coffee to the risk of first MI. METHODS AND RESULTS: The study subjects were 375 cases (303 men, 72 women) and 1293 matched referents from the population-based Northern Sweden Health and Disease Study. Coffee consumption was assessed by food frequency questionnaire. Risk estimates were calculated by conditional logistic regression. A statistically significant positive association was found between consumption of filtered coffee and MI risk in men [odds ratio for consumption > or = 4 times/day versus < or = 1 time/day 1.73 (95% CI 1.05-2.84)]. In women, a similar association was observed, but for boiled coffee [odds ratio 2.51 (95% CI 1.08-5.86)]. After adjustment for current smoking, postsecondary education, hypertension, and sedentary lifestyle, the results for women were no longer statistically significant. CONCLUSION: Consumption of filtered coffee was positively associated with the risk of a first MI in men. A similar tendency was observed for boiled coffee in women, but the result was not statistically significant in multivariate analysis. Further investigation in a larger study is warranted.

RESUMEN

The purpose of this study was to investigate the importance of enjoyment of exercise in a health care-based intervention aimed at promoting physical exercise in primary health care patients. In a controlled study design, the intervention group was offered a wide range of group exercises over 3 months, followed by support in designing their own exercise program. The control group received usual care. Enjoyment of exercise and exercise level were measured. Associations between enjoyment and exercise level were analyzed using Spearman's rank correlation coefficients. Changes in enjoyment between and within study groups were analyzed by the independent and paired t-test. Associations were found between enjoyment and exercise level (r=0.36, P<0.01), as well as between changes in enjoyment and changes in exercise level (r=0.34, P<0.01). At the 12-month follow-up, enjoyment of exercise was 25% higher in the intervention group than in the control group (P<0.01). In this group of primary health care patients, enjoyment of exercise was associated with exercise level. Enjoyment of exercise seems to be a mediator of exercise level. Furthermore, health care-based interventions seem to be able to affect enjoyment of exercise. Enjoyment of exercise may be important for the long-term effectiveness, of health care-based interventions.

RESUMEN

BACKGROUND: Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCAs) is an increasingly recognized entity. No previous study has evaluated predictors for new major adverse cardiacvascular events (MACEs) and death in patients with MINOCA. METHODS: We conducted an observational study of MINOCA patients recorded between July 2003 and June 2013 and followed until December 2013 for outcome events. Out of 199,163 MI admissions, 9092 consecutive unique patients with MINOCA were identified. The mean age was 65.5 years and 62% were women. MACE was defined as all-cause mortality, rehospitalization for acute MI, ischemic stroke and heart failure. Hazard ratio and 95% confidence interval (HR; 95% CI) was calculated using Cox-regression. RESULTS: A total of 2147 patients (24%) experienced a new MACE and 1254 patients (14%) died during the mean follow-up of 4.5 years. Independent predictors for MACE after adjustment, were older age (1.05; 1.04-1.06), diabetes (1.44; 1.21-1.70), hypertension (1.25; 1.09-1.43), current smoking (1.38; 1.15-1.66), previous myocardial infarction (1.38; 1.04-2.82), previous stroke (1.69; 1.35-2.11), peripheral vascular disease (1.55; 1.97-2.23), chronic obstructive pulmonary disease (1.63; 1.32-2.00), reduced left ventricular ejection fraction (2.00; 1.54-2.60), lower level of total cholesterol (0.88; 0.83-0.94) and higher level of creatinine (1.01; 1.00-1.03). Independent predictors for all cause death were age, current smoking, diabetes, cancer, chronic obstructive pulmonary disease, previous stroke, reduced left ventricular fraction, lower level of total cholesterol and higher levels of creatinine and CRP. CONCLUSIONS: The clinical factors predicting new MACE and death of MINOCA patients seem to be strikingly similar to factors previously shown to predict new cardiovascular events in patients with MI and obstructive coronary artery disease.

RESUMEN

BACKGROUND/OBJECTIVES: Different diets are used for weight loss. A Paleolithic-type diet (PD) has beneficial metabolic effects, but two of the largest iodine sources, table salt and dairy products, are excluded. The objectives of this study were to compare 24-h urinary iodine concentration (24-UIC) in subjects on PD with 24-UIC in subjects on a diet according to the Nordic Nutrition Recommendations (NNR) and to study if PD results in a higher risk of developing iodine deficiency (ID), than NNR diet. SUBJECTS/METHODS: A 2-year prospective randomized trial in a tertiary referral center where healthy postmenopausal overweight or obese women were randomized to either PD (n=35) or NNR diet (n=35). Dietary iodine intake, 24-UIC, 24-h urinary iodine excretion (24-UIE), free thyroxin (FT4), free triiodothyronine (FT3) and thyrotropin (TSH) were measured at baseline, 6 and 24 months. Completeness of urine sampling was monitored by para-aminobenzoic acid and salt intake by urinary sodium. RESULTS: At baseline, median 24-UIC (71.0 µg/l) and 24-UIE (134.0 µg/d) were similar in the PD and NNR groups. After 6 months, 24-UIC had decreased to 36.0 µg/l (P=0.001) and 24-UIE to 77.0 µg/d (P=0.001) in the PD group; in the NNR group, levels were unaltered. FT4, TSH and FT3 were similar in both groups, except for FT3 at 6 months being lower in PD than in NNR group. CONCLUSIONS: A PD results in a higher risk of developing ID, than a diet according to the NNR. Therefore, we suggest iodine supplementation should be considered when on a PD.

RESUMEN

A case-referent study nested within a population-based health survey investigated the associations between psychosocial stress, such as work stress and low emotional support, and future development of type 2 diabetes among occupationally working middle-aged men and women. All participants in a health survey conducted during 1989-2000 (n=33,336) in Umeå in northern Sweden, were included. We identified 191 cases, who were not diabetic initially but were diagnosed with type 2 diabetes after 5.4+/-2.6 years. Two age- and sex-matched referents were selected for each case. Multivariate logistic regression analyses and interaction effects between variables were evaluated. In women, passive or tense working situations were associated with future type 2 diabetes with odds ratios 3.6 (95% confidence interval 1.1-11.7) and 3.6 (1.0-13.3), respectively, and also low emotional support 3.0 (1.3-7.0). These associations were not seen in men. In women, they remained after adjustment for BMI, civil status and educational level, and there were also tendencies for interactions between work stress and low emotional support. In conclusion, work stress and low emotional support may increase the risk of type 2 diabetes in women, but not in men. These findings contribute to our understanding of psychosocial stress as potential risk factors for type 2 diabetes in a Swedish population.

RESUMEN

A multifactorial grading score (MGS) for invasive squamous cell carcinoma of the uterine cervix has demonstrated its capacity to predict survival in a 5-10 year perspective and metastasis frequencies, and is a valuable tool for treatment schedules. In this study it was shown that the power of prognosis is valid even up to 20 years. In this material from 619 cervical carcinoma patients the MGS scores turned out to remain as strong as earlier proven. Earlier studies have shown that MGS is superior to other mono- and multifactorial grading systems, histological differentiation into cell types, age, clinical stage, irradiation and DNA-analysis. Treatment of cervical squamous cell carcinoma is more specific today to meet the patients' need for instance to preserve fertility or to minimize operation and eventually radiotherapy. The MGS score is a strong prognostic tool in patients with cervical carcinoma.
