Cardiovascular and cancer mortality in relation to dietary polychlorinated biphenyls and marine polyunsaturated fatty acids: A nutritional-toxicological aspect of fish consumption
Background. Co-exposure to environmental contaminants
present in fish could mitigate the beneficial
effects of fish consumption and possibly explain
the lack of association observed for mortality in
some geographical regions.
Objective. To assess the independent associations of
dietary exposure to polychlorinated biphenyls
(PCBs) and long-chain omega-3 fish fatty acids
intake with cardiovascular and cancer mortality.
Methods. We used the prospective population-based
Swedish Mammography Cohort and the Cohort of
Swedish Men comprising 32 952 women and 36 545
men, free from cancer, cardiovascular disease and
diabetes at baseline in 1998. Validated estimates of
dietary PCBs and long-chain omega-3 fish fatty acids
[i.e. eicosapentaenoic acid (EPA) and docosahexaenoic
acid (DHA)] intake were obtained via a food
frequency questionnaire at baseline. Information on
death was ascertained through register linkage.
Results. During a mean follow-up of 15.5 years, we
ascertained 16 776 deaths. We observed for cardiovascular
mortality, comparing extreme quintiles
in multivariable models mutually adjusted for
PCBs and EPA-DHA, dose-dependent associations
for dietary PCB exposure, hazard ratio (HR) 1.31
(CI 95%: 1.08 to 1.57; P-trend 0.005) and for
dietary EPA-DHA intake, HR 0.79 (CI 95%: 0.66 to
0.95; P-trend 0.041). For cancer mortality, no clear
associations were discerned.
Conclusion. The beneficial effect of fish consumption
on the cardiovascular system seems compromised
by co-exposure to PCBs – one likely explanation for
the inconsistent associations observed between
fish consumption and mortalityThe Swedish Research Council under the grant no 2017-00822 and 2017-00644 (SIMPLER) supported the stud

High-quality intake of carbohydrates is associated with lower prevalence of subclinical atherosclerosis in femoral arteries: The AWHS study
Background and aims: High-quality of the carbohydrates consumed, apart from their total amount, appear to protect from cardiovascular disease (CVD). However, the relationship between the quality of carbohydrates and the early appearance of atherosclerosis has not yet been described. Our objective was to estimate the association between the quality of dietary carbohydrates and subclinical atherosclerosis in femoral and carotid arteries. Methods: Cross-sectional study of femoral and carotid atherosclerosis assessed using ultrasounds of 2074 middle-aged males, 50.9 (SD 3.9) years old, with no previous CVD, and pertaining to the Aragon Workers’ Health Study (AWHS) cohort. Food frequency questionnaires were used to calculate a carbohydrate quality index (CQI) defined as: consumption of dietary fiber, a lower glycemic index, the ratio of whole grains/total grains, and the ratio of solid carbohydrates/total carbohydrates. The presence of plaques across four CQI intervals was studied using adjusted logistic regression models. Results: The CQI showed a direct inverse association with subclinical atherosclerosis in femoral territories. Participants with a higher consumption of high-quality carbohydrates (13–15 points) were less likely to have femoral plaques when compared with participants in the lowest index interval (4–6 points) (OR = 0.59; 95% CI = 0.39, 0.89; p = 0.005). No association was found between the CQI and the presence of subclinical atherosclerosis in carotid territories. A lower consumption of high-quality carbohydrates tended to be associated with a greater atherosclerosis extension, considered as the odds for having more affected territories (p = 0.011). Conclusions: Among middle-aged males, a high-quality intake of carbohydrates is associated with a lower prevalence of femoral artery subclinical atherosclerosis when compared with a lower consumption. Thus, indicating an early relationship between the quality of carbohydrates and the development of CVD. © 2021 The Author(s
Ultra-processed food consumption is associated with renal function decline in older adults: A prospective cohort study
Ultra-processed food (UPF) consumption has been associated with increased risk of cardiovascular risk factors and mortality. However, little is known on the UPF effect on renal function. The aim of this study is to assess prospectively the association between consumption of UPF and renal function decline. This is a prospective cohort study of 1312 community-dwelling individuals aged 60 and older recruited during 2008–2010 and followed up to December 2015. At baseline, a validated dietary history was obtained. UPF was identified according to NOVA classification. At baseline and at follow-up, serum creatinine (SCr) and estimated glomerular filtration rate (eGFR) levels were ascertained and changes were calculated. A combined end-point of renal decline was considered: SCr increase or eGFR decreased beyond that expected for age. Logistic regression with adjustment for potential confounders was performed. During follow-up, 183 cases of renal function decline occurred. The fully adjusted odds ratios (95% CI) of renal function decline across terciles of percentage of total energy intake from UPF were 1.56 (1.02–2.38) for the second tercile, and 1.74 (1.14–2.66) for the highest tercile; p-trend was 0.026. High UPF consumption is independently associated with an increase higher than 50% in the risk of renal function decline in Spanish older adults
Rationale of the association between Mediterranean diet and the risk of frailty in older adults and systematic review and meta-analysis
Frailty is a geriatric syndrome whose frequency is increasing in parallel with population aging and is of great interest due to its dire consequences: increased disability, hospitalizations, falls and fractures, institutionalization, and mortality. Frailty is multifactorial but nutritional factors, which are modifiable, play a crucial role in its pathogenesis. Epidemiologic evidence supports that high-quality dietary patterns can prevent, delay or even reverse the occurrence of frailty. In order to add new knowledge bridging the gap as the main purpose of the present article we performed a comprehensive review of the rationale behind the association of MedDiet with frailty and a systematic review and meta-analysis updating the latest ones published in 2018 specifically examining the relationship of Mediterranean diet (MedDiet) and incident frailty. Adding the updated information, our results confirmed a robust association of a higher adherence to MedDiet with reduced incident frailty. Key components of the MedDiet, i.e., abundant consumption of vegetables and fruit as well as the use of olive oil as the main source of fat, all of which have been associated with a lower incidence of frailty, may help explain the observed benefit. Future well-designed and sufficiently large intervention studies are needed to confirm the encouraging findings of the current observational evidence. Meanwhile, based on the existing evidence, the promotion of MedDiet, a high-quality dietary pattern, adapted to the conditions and traditions of each region, and considering lifelong and person-tailored strategies, is an open opportunity to reduced incident frailty. This could also help counteract the worrying trend towards the spread of unhealthy eating and lifestyle models such as those of Western diets that greatly contribute to the genesis of chronic non-communicable diseases and disability
Association of cooking patterns with inflammatory and cardio-metabolic risk biomarkers
Diet has been clearly associated with cardiovascular disease, but few studies focus on the influence of cooking and food preservation methods on health. The aim of this study was to describe cooking and food preservation patterns, as well as to examine their association with inflammatory and cardio-metabolic biomarkers in the Spanish adult population. A cross-sectional study of 10, 010 individuals, representative of the Spanish population, aged 18 years or over was performed using data from the ENRICA study. Food consumption data were collected through a face-to-face dietary history. Cooking and food preservation patterns were identified by factor analysis with varimax rotation. Linear regression models adjusted for main confounders were built. Four cooking and food preservation patterns were identified. The Spanish traditional pattern (positively correlated with boiling and sautéing, brining, and light frying) tends to be cardio-metabolically beneficial (with a reduction in C-reactive protein (-7.69%)), except for high density lipoprotein cholesterol (HDL-c), insulin levels, and anthropometrics. The health-conscious pattern (negatively correlated with battering, frying, and stewing) tends to improve renal function (with a reduction in urine albumin (-9.60%) and the urine albumin/creatinine ratio (-4.82%)). The youth-style pattern (positively correlated with soft drinks and distilled alcoholic drinks and negatively with raw food consumption) tends to be associated with good cardio-metabolic health except, for lower HDL-c (-6.12%), higher insulin (+6.35%), and higher urine albumin (+27.8%) levels. The social business pattern (positively correlated with the consumption of fermented alcoholic drinks, food cured with salt or smoke, and cured cheese) tends to be detrimental for the lipid profile (except HDL-c), renal function (urine albumin +8.04%), diastolic blood pressure (+2.48%), and anthropometrics. Cooking and food preservation patterns showed a relationship with inflammatory and cardio-metabolic health biomarkers. The Spanish traditional pattern and the health-conscious pattern were associated with beneficial effects on health and should be promoted. The youth-style pattern calls attention to some concerns, and the social business pattern was the most detrimental one. These findings support the influence of cooking and preservation patterns on health
Urinary phosphate is associated with cardiovascular disease incidence
Elevated phosphate (P) in urine may reflect a high intake of inorganic P salts from food additives. Elevated P in plasma is linked to vascular dysfunction and calcification. Objective, To explore associations between P in urine as well as in plasma and questionnaire-estimated P intake, and incidence of cardiovascular disease (CVD). Methods, We used the Swedish Mammography Cohort-Clinical, a population-based cohort study. At baseline (2004–2009), P was measured in urine and plasma in 1625 women. Dietary P was estimated via a food-frequency questionnaire. Incident CVD was ascertained via register-linkage. Associations were assessed using Cox proportional hazards regression. Results, After a median follow-up of 9.4 years, 164 composite CVD cases occurred (63 myocardial infarctions [MIs] and 101 strokes). Median P (percentiles 5–95) in urine and plasma were 2.4 (1.40–3.79) mmol/mmol creatinine and 1.13 (0.92–1.36) mmol/L, respectively, whereas dietary P intake was 1510 (1148–1918) mg/day. No correlations were observed between urinary and plasma P (r = −0.07) or dietary P (r = 0.10). Urinary P was associated with composite CVD and MI. The hazard ratio of CVD comparing extreme tertiles was 1.57 (95% confidence interval 1.05, 2.35; P trend 0.037)—independently of sodium excretion, the estimated glomerular filtration rate, both P and calcium in plasma, and diuretic use. Association with CVD for plasma P was 1.41 (0.96, 2.07; P trend 0.077). Conclusion, Higher level of urinary P, likely reflecting a high consumption of highly processed foods, was linked to CVD. Further investigation is needed to evaluate the potential cardiovascular toxicity associated with excessive intake of P beyond nutritional requirement
Dimensiones del arco posterior de C2 para el guiado de tornillos translaminares. Estudio radiológico en población española
Background. To describe the feasibility of the posterior
arch of C2 accepting two crossing screws in the Spanish
population.
Methods. One hundred and fifty patients who underwent
a routine neck CT scan for non-cervical pathology were
enrolled. Submillimeter slices (thickness 0.7 mm) every
0.4 mm were performed with a 64 multi-detector CT scan,
which allows isometric measurements. We measured the
length and height of the cortical and cancellous (endomedullar) region of the lamina and the spinous process,
inclination, maximal screw length and spinolaminar angle.
Results. The average (standard deviation) measurements
of the lamina were: width of the left cortical 7.2 (1.5) mm,
right cortical 6.9 (1.3) mm, width of the cancellous part of
the left lamina 4.8 (1.5) mm, right side 4.6 (1.4) mm. The
mean left cortical height was 13.0 (1.5) mm and 13.1 (1.6)
mm for the right. The mean height of the cancellous part
was 9.0 mm for both sides. The average measurements of
the spinous process were: cortical length 15.7 (3.5) mm,
endomedullar length 12.5 (3.9) mm; cortical height 11.9
(2.2) mm, endomedullar height 8.4 (2.1) mm; spinolaminar angle 49º (4); the maximum screw length 3.18 cm, and
the inclination angle 143º.
Conclusion. A CT scan with submillimeter slices is necessary in order to avoid malpositioning of the screws. The
outer cortical measurements are 2 to 4 mm bigger than
the endomedullar ones. Taking into account the dimensions of the spinous process, 24% of the population would
not be candidates for this crossing screw technique.Fundamento. Describir la capacidad del arco posterior

Método. Se reclutaron 150 pacientes a los que se les realizó un escáner del cuello por patología no cervical. Para
el estudio se utilizó un 64 multi-detector TAC realizando
cortes submilimétricos (0,7 mm de grosor) cada 0,4 mm,
permitiendo obtener medidas isométricas. Se midieron
anchura y altura cortical y endomedular de la lámina y
de la espinosa, inclinación de la lámina, máxima longitud
de tornillo y ángulo espinolaminar.
Resultados. Las media (desviación estándar) de las medidas de la lámina fueron: anchura cortical izquierda 7.2
(1,5) mm, cortical derecho 6,9 (1,3) mm, anchura endomedular izquierda 4,8 (1,5) mm, derecha 4,6 (1,4) mm La
altura media cortical izquierda fue 13,0 (1,5) mm y de 13,1
(1,6) mm para la derecha. La altura media endomedular
fue de 9,0 mm en ambos lados. Las medidas medias de la
espinosa fueron: longitud media cortical 15,7 (3,5) mm,
longitud endomedular 12,5 (3,9) mm; altura cortical 11,9
(2,2) mm, altura endomedular de 8,4 (2,1) mm; ángulo espinolaminar 49º (4); la longitud máxima de tornillo 3,18
cm; y el ángulo de inclinación 143º.
Conclusiones. Para evitar la colocación errónea de los tornillos es necesario un estudio de TAC con cortes submilimétricos. La diferencia entre las medidas corticales y endomedulares oscila entre 2 y 4 mm. Teniendo en cuenta las dimensiones
de la espinosa, un 24% de la población no sería candidato a
esta técnica de tornillos cruzados translaminares
Trajectories of alcohol consumption during life and the risk of developing breast cancer
Background: Whether there are lifetime points of greater sensitivity to the deleterious effects of alcohol intake on the breasts remains inconclusive. Objective: To compare the influence of distinctive trajectories of alcohol consumption throughout a woman’s life on development of breast cancer (BC). Methods: 1278 confirmed invasive BC cases and matched (by age and residence) controls from the Epi-GEICAM study (Spain) were used. The novel group-based trajectory modelling was used to identify different alcohol consumption trajectories throughout women’s lifetime. Results: Four alcohol trajectories were identified. The first comprised women (45%) with low alcohol consumption (<5 g/day) throughout their life. The second included those (33%) who gradually moved from a low alcohol consumption in adolescence to a moderate in adulthood (5 to <15 g/day), never having a high consumption; and oppositely, women in the third trajectory (16%) moved from moderate consumption in adolescence, to a lower consumption in adulthood. Women in the fourth (6%) moved from a moderate alcohol consumption in adolescence to the highest consumption in adulthood (=15 g/day), never having a low alcohol consumption. Comparing with the first trajectory, the fourth doubled BC risk (OR 2.19; 95% CI 1.27, 3.77), followed by the third (OR 1.44; 0.96, 2.16) and ultimately by the second trajectory (OR 1.17; 0.86, 1.58). The magnitude of BC risk was greater in postmenopausal women, especially in those with underweight or normal weight. When alcohol consumption was independently examined at each life stage, =15 g/day of alcohol consumption in adolescence was strongly associated with BC risk followed by consumption in adulthood. Conclusions: The greater the alcohol consumption accumulated throughout life, the greater the risk of BC, especially in postmenopausal women. Alcohol consumption during adolescence may particularly influence BC risk. © 2021, The Author(s)
Mediterranean diet and invasive breast cancer risk in the predimed trial
Trabajo presentado en el X Congreso Internacional de la Dieta Mediterránea, celebrado en Barcelona (España) del 02 al 03 de abril de 2014.[Introduction]: Rates of breast cancer incidence have been rising over the past 3 decades. Dietary factors may play a role in the risk of breast cancer. Some observational cohort studies have suggested that the Mediterranean diet may reduce the risk of breast cancer but no randomized controlled trial had investigated this issue. We aimed to evaluate the effect of two interventions with Mediterranean diet on the primary prevention of breast cancer in a randomized controlled trial.
[Methods]: The PREDIMED study (Prevención con Dieta Mediterránea) is a randomized, singleblind, and controlled trial conducted in Spanish primary healthcare centres. Out of 4,282 women recruited (aged 60 to 80 years), 1,478 were assigned to a Mediterranean diet supplemented with extra-virgin olive oil, 1,288 to a Mediterranean diet supplemented with mixed nuts and 1,393 to a control diet (advice to reduce dietary fat). Primary analyses were performed on an intention-to-treat basis. Poisson regression analyses were used to assess the relationship between the nutritional intervention and the incidence of confirmed invasive breast cancer.
[Results]: After a median of 4.3 years after randomization, participants in both Mediterranean diet groups (extra-virgin olive oil or nuts) had a 55% relative reduction (95%CI: 9% to 78%) in the risk of invasive breast cancer compared with participants assigned to a control group (with the recommendation to follow a low-fat diet). Observed rates (per 1000 person-years) were 1.14, 1.82 and 2.90 for the Mediterranean diet with extra-virgin olive oil group, the Mediterranean diet supplemented with nuts group and the control group, respectively. The multivariable-adjusted rate ratios versus the control group were 0.34 (95% CI: 0.14 to 0.83) for the Mediterranean diet with extra-virgin olive oil group, and 0.60 (95% CI: 0.26 to 1.35) for the Mediterranean diet supplemented with nuts group.
[Conclusions]: This is the first large randomized trial assessing the role of a dietary pattern on breast cancer incidence. Our results suggest that an intervention promoting adherence to the Mediterranean dietary pattern, specially when it is supplemented with extra-virgin olive oil, may contribute to a substantial reduction in the incidence of invasive breast cancer risk in women 60 years and older. However, a longer follow-up of our participants is needed to obtain more precise estimates
