Everything causes cancer? Beliefs and attitudes towards cancer prevention among anti-vaxxers, flat earthers, and reptilian conspiracists: online cross sectional survey.

OBJECTIVE: To evaluate, using an online non-probability sample, the beliefs about and attitudes towards cancer prevention of people professing vaccination scepticism or conspiracy theories. DESIGN: Cross sectional survey. SETTING: Data collected mainly from ForoCoches (a well known Spanish forum) and other platforms, including Reddit (English), 4Chan (English), HispaChan (Spanish), and a Spanish language website for cancer prevention (mejorsincancer.org) from January to March 2022. PARTICIPANTS: Among 1494 responders, 209 were unvaccinated against covid-19, 112 preferred alternative rather than conventional medicine, and 62 reported flat earth or reptilian beliefs. MAIN OUTCOME MEASURES: Cancer beliefs assessed using the Cancer Awareness Measure (CAM) and Cancer Awareness Measure Mythical Causes Scale (CAM-MYCS) (both validated tools). RESULTS: Awareness of the actual causes of cancer was greater (median CAM score 63.6%) than that of mythical causes (41.7%). The most endorsed mythical causes of cancer were eating food containing additives or sweeteners, feeling stressed, and eating genetically modified food. Awareness of the actual and mythical causes of cancer among the unvaccinated, alternative medicine, and conspiracy groups was lower than among their counterparts. A median of 54.5% of the actual causes was accurately identified among each of the unvaccinated, alternative medicine, and conspiracy groups, and a median of 63.6% was identified in each of the three corresponding counterparts (P=0.13, 0.04, and 0.003, respectively). For mythical causes, medians of 25.0%, 16.7%, and 16.7% were accurately identified in the unvaccinated, alternative medicine, and conspiracy groups, respectively; a median of 41.7% was identified in each of the three corresponding counterparts (P<0.001 in adjusted models for all comparisons). In total, 673 (45.0%) participants agreed with the statement "It seems like everything causes cancer." No significant differences were observed among the unvaccinated (44.0%), conspiracist (41.9%), or alternative medicine groups (35.7%), compared with their counterparts (45.2%, 45.7%, and 45.8%, respectively). CONCLUSIONS: Almost half of the participants agreed that "It seems like everything causes cancer," which highlights the difficulty that society encounters in differentiating actual and mythical causes owing to mass information. People who believed in conspiracies, rejected the covid-19 vaccine, or preferred alternative medicine were more likely to endorse the mythical causes of cancer than their counterparts but were less likely to endorse the actual causes of cancer. These results suggest a direct connection between digital misinformation and consequent erroneous health decisions, which may represent a further preventable fraction of cancer.

Stressful Life Events and Distress in Breast Cancer: A 5-Years Follow-Up.

Background/Objective: Environmental factors such as psychosocial stress have demonstrated to have an impact on the breast cancer (BC) course. This study aims to explore the impact of psychotherapy and stressful life events (SLE) on BC survivors' illness trajectories. Method: 68 women with BC underwent Positive Psychotherapy or Cognitive-Behavioral Stress Management and 37 patients were included as a control group. The effects of distress reduction and SLE on their 5-year recurrence were investigated. Additional analyses examined the effect of receiving vs. not receiving psychotherapy and of the type of therapy on survival and disease-free interval, DFI. Results: A one-point decrease of the Hospital Anxiety and Depression Scale (HADS) after psychotherapy predicted a lower risk of 5-year recurrence, OR = 0.84, p = .037, 95% CI = 0.71-0.99). Also, a one point-increase in the number threatening SLE (OR = 1.92; p = .028, 95% CI = 1.07-3.43) was related to higher 5-year recurrence. Conclusions: The findings highlight the necessity of studying not only a given situation (i.e., psychotherapy, SLE) but its specific impact on individuals.

Antecedentes/Objetivo: El estrés psicosocial ha demostrado tener un impacto en la evolución del cáncer de mama (CM). Este estudio tiene como objetivo explorar el impacto de la psicoterapia y de los acontecimientos vitales estresantes (AVE) en la supervivencia de pacientes con CM. Método: 113 mujeres con CM recibieron psicoterapia positiva o terapia cognitivo-conductual para manejar el estrés y 37 se incluyeron como grupo control. Se analizaron los efectos de la reducción de la Escala de Ansiedad y Depresión Hospitalaria (HADS) y de los AVE sobre la recurrencia a los cinco años, así como el efecto de recibir psicoterapia y del tipo de enfoque d esta sobre la supervivencia. Resultados: La reducción de un punto en la HADS después de recibir psicoterapia predijo un menor riesgo de recurrencia, OR = 0,84, p = 0,037, IC 95% = 0,71-0,99. Además, cada aumento en el número de AVE vividos como amenazantes (OR = 1,92; p = 0,028, 95% CI = 1,07-3,43) se relacionó con una mayor recurrencia. Conclusiones: Los resultados indican la necesidad de estudiar no solo la presencia de un evento potencialmente impactante en la conducta (psicoterapia o AVE) sino el efecto especifico que ha tenido en cada individuo.

6-Year Risk of Developing Lung Cancer in Spain: Analysis by Autonomous Communities / Riesgo a 6 años de desarrollar cáncer de pulmón en España: análisis por comunidades autónomas

Introduction: Lung cancer screening with low-dose computed tomography (LDCT) has been proposed as a strategy to reduce lung cancer mortality. Since LDCT has side effects there is a need to carefully select the target population for screening programmes. Because in Spain health competences are transferred to the seventeen Autonomous Communities (ACs), the present paper aims to identify individuals at high risk of developing lung cancer in the different ACs. Methods: We used the 2011–2012 data of the Spanish National Interview Health Survey (n=21,006) to estimate the proportion of individuals at high risk of developing lung cancer using a 6-year prediction model (PLCOm2012). This proportion was then extrapolated into absolute figures for the Spanish population, using the population census data of 2018 from the National Institute of Statistics. Results: The proportion of individuals aged 50–74 with a risk of lung cancer ≥2% was 9.5% (15.9% in men, 3.5% in women). This proportion ranged from 6.6% in Región de Murcia to 12.7% in Andalucía and 13.0% in Extremadura. When extrapolated to the Spanish population, it was estimated that a total of 1,341,483 individuals may have a 6-year risk of lung cancer ≥2%. Conclusions: The present study is the first one that evaluated the number of individuals at high risk of developing lung cancer in the different Spanish ACs using a prediction model and selecting people with a 6-year risk ≥2%. Further studies should assess the cost and effectiveness associated to the implementation of a lung cancer screening programme to such population. (AU)

Introducción: La detección del cáncer de pulmón con tomografía computarizada de baja dosis se ha propuesto como una estrategia para reducir la mortalidad por dicho cáncer. Como la tomografía computarizada de baja dosis tiene efectos secundarios, es necesario seleccionar cuidadosamente la población objetivo para los programas de cribado. Debido a que en España las competencias de salud están transferidas a las 17 comunidades autónomas, el presente trabajo tiene como objetivo identificar a las personas con alto riesgo de desarrollar cáncer de pulmón en las diferentes comunidades autónomas. Métodos: Utilizamos los datos de 2011-2012 de la Encuesta Nacional de Salud de España (n=21.006) para estimar la proporción de individuos con alto riesgo de desarrollar cáncer de pulmón utilizando un modelo de predicción a 6 años (PLCOm2012). Esta proporción se extrapoló en cifras absolutas para la población española, utilizando los datos del censo de población de 2018 del Instituto Nacional de Estadística. Resultados: La proporción de individuos de 50 a 74 años con riesgo de cáncer de pulmón≥2% fue del 9,5% (15,9% en hombres, 3,5% en mujeres). Esta proporción osciló entre el 6,6% en la Región de Murcia, el 12,7% en Andalucía y el 13,0% en Extremadura. Cuando se extrapoló a la población española, se estimó que un total de 1.341.483 individuos podrían tener un riesgo de cáncer de pulmón a los 6 años≥2%. Conclusiones: El presente estudio es el primero que evaluó el número de individuos con alto riesgo de desarrollar cáncer de pulmón en las diferentes comunidades autónomas españolas utilizando un modelo predictivo y seleccionando personas con un riesgo a los 6 años≥2%. Se deberían realizar estudios adicionales para evaluar el coste y la efectividad asociados a la implementación de un programa de cribado de cáncer de pulmón para dicha población. (AU)

Text messaging as a tool to improve cancer screening programs (M-TICS Study): A randomized controlled trial protocol.

BACKGROUND: Short message service (SMS) based interventions are widely used in healthcare and have shown promising results to improve cancer screening programs. However, more research is still needed to implement SMS in the screening process. We present a study protocol to assess the impact on health and economics of three targeted SMS-based interventions in population-based cancer screening programs. METHODS/DESIGN: The M-TICs study is a randomized controlled trial with a formal process evaluation. Participants aged 50-69 years identified as eligible from the colorectal cancer (CRC) and breast cancer (BC) screening program of the Catalan Institute of Oncology (Catalonia, Spain) will be randomly assigned to receive standard invitation procedure (control group) or SMS-based intervention to promote participation. Two interventions will be conducted in the CRC screening program: 1) Screening invitation reminder: Those who do not participate in the CRC screening within 6 weeks of invite will receive a reminder (SMS or letter); 2) Reminder to complete and return fecal immunochemical test (FIT) kit: SMS reminder versus no intervention to individuals who have picked up a FIT kit at the pharmacy and they have not returned it after 14 days. The third intervention will be performed in the BC screening program. Women who had been screened previously will receive an SMS invitation or a letter invitation to participate in the screening. As a primary objective we will assess the impact on participation for each intervention. The secondary objectives will be to analyze the cost-effectiveness of the interventions and to assess participants' perceptions. EXPECTED RESULTS: The results from this randomized controlled trial will provide important empirical evidence for the use of mobile phone technology as a tool for improving population-based cancer screening programs. These results may influence the cancer screening invitation procedure in future routine practice. TRIAL REGISTRATION: Registry: NCT04343950 (04/09/2020); clinicaltrials.gov.

Role of community pharmacies in a population-based colorectal cancer screening program.

In Catalonia (Spain), population-based colorectal cancer (CRC) screening offers biennial fecal occult blood testing to men and women aged 50-69 years old. The program is organized in screening hubs, most of which use a pharmacy-based model to distribute and collect fecal immunochemical test (FIT) kits The comprehensive evaluation of CRC screening programs, which include the role and implications of pharmacy involvement, is essential to ensure program quality and identify areas for further improvement. The present study aimed to assess the adherence of community pharmacies to the CRC screening program and to analyze data on FIT kit distribution and collection in the Metropolitan area of Barcelona (Catalonia, Spain). Time to FIT completion was assessed by Kaplan-Meier estimation, and with the log-rank test. A Cox regression model was used to adjust for other variables associated with the completion of FIT such as sex, age, deprivation score index and previous screening behavior. Overall, 82.4% of pharmacies adhered with CRC screening program. Out of 82,902 FIT kits distributed to screening invitees 77,524 completed FIT kits were returned to pharmacies (93.5%) with a participation of 39.8% among the 193,766 invitees. From those who completed a FIT, the median time to return the kit was 3 days. FIT completion time was significantly lower among women, older age, high deprivation score index and previous CRC screening (p < 0.005). Our findings highlight the large involvement of community pharmacists with CRC screening program as well as a high quality in the process of FIT distribution and collection.

An exploratory study in breast cancer of factors involved in the use and communication with health professionals of Internet information.

OBJECTIVE: To study the impact of the spontaneous use of Internet on breast cancer patients and on their relationship with health professionals. METHODS: A mixed methodology was used. Two questionnaires were designed through three focus groups, and then administered to 186 patients and 59 professionals in order to assess: (1) patients' use of Internet for health-related information and (2) the impact of this information on patients' psychological outcomes and on their relationship with professionals. RESULTS: Patients spent more time looking for illness-related information after diagnosis, using interactive communities more than static information websites. Patients and professionals disagreed about the use of Internet in terms of the knowledge it provides, and its psychological impact. The main barrier reported by patients regarding the sharing of online information with their professionals was the belief that it would damage their relationship. CONCLUSIONS: Both professionals and patients have a protectionist conception of the therapeutic relationship. This attitude tends to dismiss the positive impact that the use of Internet and the new communication tools may have in cancer patients. New resources should provide an "Internet Prescription" and modes of interaction to facilitate a more open digital communication.

Physical Test to Estimate Suitable Workloads for an Exercise Program in Breast Cancer Survivors.

Guillamó, E, Travier, N, Oviedo, GR, Fonseca-Nunes, A, Alamo, JM, Cos, F, Roca, A, Niño, O, Agudo, A, and Javierre, C. Physical test to estimate suitable workloads for an exercise program in breast cancer survivors. J Strength Cond Res 34(12): 3593-3599, 2020-Epidemiologic studies suggest that patients with breast cancer who gain weight after diagnosis have a higher risk of recurrence and death. Regular physical exercise can help minimize postdiagnosis weight gain. The objective of the study was to assess the effectiveness of a physical test for individualizing the workloads used during a fitness program. To continuously individualize the intensity of the training, a test was designed and integrated into the sessions. The test consisted in monitoring heart rate and workload during 2 bouts of cycling at moderate intensity. The workload parameters recorded during the tests were later used as reference values to plan the intensity of the next in-person training sessions. The 5 tests conducted during the 12 weeks of the intervention showed significant differences in intensity (F = 3.034, p = 0.047). Compared with the first evaluation, the intensities measured during the third, fourth, and fifth tests presented increases of 9.9% (p = 0.02), 13.2% (p = 0.019), and 17.5% (p = 0.002), respectively. A significant increase in workload with respect to body weight was observed in the physical assessment performed after the program (t = 13.2, p = 0.0001). The peak oxygen consumption with respect to body weight (peak V[Combining Dot Above]O2) achieved by the subjects during the assessment at the end of the program had also increased (t = 9.72, p = 0.0001). The intensity test, introduced in the training sessions along with the physical exercise program, was an easy-to-use, practical tool for monitoring intensity. It allows an adjustment of the workload over the program period that respects the individual progression of each patient.

Communication Channels Used by Women to Contact a Population-Based Breast Cancer Screening Program in Catalonia, Spain.

Communication is a corner stone of population-based breast cancer screening programs that need to invite all the women from their target population and provide them with balanced information on screening to guaranty informed participation. Invited women also need to be able to contact screening programs to get further information on screening procedures and/or cancel and reschedule appointments. This study describes the communication channels used by women invited for breast cancer screening to contact the program. The study population consisted of 141,684 women, aged 50-69 years, who were invited during 2015-2016 for screening by the Catalan Breast Cancer Screening Program (Spain). Multiple logistic regression models were performed to assess the association between age, screening history, socioeconomic status and reasons for contacting the program and the outcome variables (contact with the program; contact through information and communication technology (ICT) channels). Among the 141,684 women invited for BC screening, 22.5% contacted the screening office mainly to reschedule (42.2%) and cancel (29.2%) appointments. While the communication channel mostly used was the telephone, 24.8% of the women used ICT. ICT was more frequently used by women who had never been screened. Women who wanted to change their appointment were 65% (OR 1.65, 95%CI 1.54-1.76) more likely to use ICT than women who wanted to cancel it. This study showed the need to reinforce communication between women and breast cancer screening programs and the importance of offering communication channels suiting all women's needs to facilitate appointments' rescheduling and cancelling and therefore improve screening programs' efficiency.

Longitudinal Adherence to Immunochemical Fecal Occult Blood Testing vs Guaiac-based FOBT in an Organized Colorectal Cancer Screening Program.

Longitudinal adherence is a critical component of the efficacy of stool-based screening programs because they should be repeated every 1-2 years. Few data have been published on the uptake in multiple rounds of fecal occult blood test-based (FOBT) colorectal cancer (CRC) screening. We calculated two measures of longitudinal adherence to biennial FOBT (guaiac fecal occult blood test:gFOBT or fecal immunochemical test:FIT) to better understand its impact on the programmatic effectiveness of a population-based CRC screening program (2000-2017). Ongoing population-based CRC program of men and women aged 50-69 years. Variables: Age at first CRC screening invitation, sex, number of screening invitations, number of screens, deprivation score, and uptake rate. Logistic regression models were used to assess the independent effect of sex, age at first invitation, deprivation, and the type of screening test offered on adherence. The uptake rate for guaiac fecal occult blood test (gFOBT) was 23.9%, and for the fecal immunochemical test (FIT), it was 37.4%. The overall rate of consistently screened invitees after seven rounds of screening was 14.2%, being 20.6% for those individuals who used FIT and 14.3% for those who used gFOBT. Factors associated with continued participation (consistent vs. inconsistent screenees) showed that the longitudinal adherence was associated with age, screening test used, and number of invitations. Continued participation was lower in individuals who were screened using FIT than among those screened using gFOBT [OR, 0.68; 95% confidence interval (CI), 0.57-0.81]. The overall rate of consistently screened invitees for colorectal cancer screening was higher with FIT than gFOBT. Studying the rate of individuals being current for screening may help to anticipate potential benefits before the long-term outcome data are available.

Feasibility and Effects of Structured Physical Exercise Interventions in Adults with Relapsing-Remitting Multiple Sclerosis: A Pilot Study.

Multiple sclerosis (MS) is a chronic neurological disease which affects young adults at a time of maximum personal, professional and social growth. Recent guidelines on physical activity have established that exercise is an essential component of the clinical management of people with MS with mild or moderate degree of disability. The main purpose of this study was to test the feasibility and the effects of two different 40-week structured physical exercise interventions (a supervised high intensity interval training plus home exercise program and a self-applied home-based exercise program) on clinical evolution, psychological wellbeing, quality of life, fatigue, cardiorespiratory fitness, strength and balance of people with MS. Twenty-nine participants with relapsing-remitting MS (RRMS) participated in this study. All of them were fully ambulatory and with minimal disability (Expanded Disability Status Scale <3), for at least the last six months. Participants selected to be part of a combined face-to-face plus home exercise group (CFTFG; n = 8); a self-applied home-based exercise group (HG; n = 11) or a control group (CG; n = 10). A total of 23 participants completed the protocol (79.3%), of which 8 participants (100%) from the CFTFG, 7 (63.6%) from the HG and 8 (80%) from the CG. During the first 20-weeks of training, adherence from the CFTFG reached 77.5% and from the HG reached 50 %. During the second 20-weeks of training, adherence from the CFTFG reached 62.5% and from the HG reached 45.4%. After 20-weeks of training, a significant improvement in the absolute VO2 peak and in the 30-second sit to stand test was observed in the CFTFG (all p < .05). This study confirms that offering a 40-week structured exercise programme to a group of fully ambulatory and minimally disabled persons with RRMS is feasible and safe. Any adverse event related to the trial was reported by the participants.

Changes in metabolic risk, insulin resistance, leptin and adiponectin following a lifestyle intervention in overweight and obese breast cancer survivors.

Adiposity and physical activity are modifiable factors that could be important determinants of breast cancer (BC) prognosis through their effects on endogenous reproductive hormones, chronic inflammation and metabolic changes. Therefore, it is necessary to evaluate whether offering lifestyle interventions to BC survivors could affect the levels of certain biomarkers involved in these mechanisms. We designed a pre-post intervention study offering diet and exercise sessions over 12 weeks to 42 overweight/obese BC survivors. Before and after the intervention, we obtained dietary information, anthropometry and cardiorespiratory fitness (CRF) measurements and blood samples to measure metabolic risk, insulin resistance and adipokines biomarkers. Wilcoxon signed-rank tests and Spearman partial correlation coefficients were used to compare pre- and post-measurements and assess the correlations between changes in biomarkers and changes in anthropometry and CRF. Breast cancer survivors showed significant improvements in metabolic risk biomarkers and insulin resistance indicators along with a non-significant leptin decrease and a significant adiponectin decrease. The improvements in metabolic risk biomarkers, insulin resistance indicators and leptin were moderately correlated (0.32 ≤ |r| ≤ 0.55) with the decrease in body mass index and the increase in CRF. Diet and exercise interventions implemented in overweight/obese BC survivors may improve metabolic risk, insulin resistance and leptin biomarkers.

Identifying high-risk individuals for lung cancer screening: Going beyond NLST criteria.

BACKGROUND: There are two main types of strategies to identify target population for lung cancer screening: 1) strategies based on age and cumulative smoking criteria, 2) risk prediction models allowing the calculation of an individual risk. The objective of this study was to compare different strategies to identify the proportion of the Spanish population at high risk of developing lung cancer, susceptible to be included in a lung cancer screening programme. METHODS: Cross-sectional study. We used the data of the Spanish National Interview Health Survey (ENSE) of 2011-2012 (21,006 individuals) to estimate the proportion of participants at high risk of developing lung cancer. This estimation was performed using the U.S. national lung screening trial (NLST) criteria and a 6-year prediction model (PLCOm2012), both independently and in combination. RESULTS: The prevalence of individuals at high risk of developing lung cancer according to the NLST criteria was 4.9% (7.9% for men, 2.4% for women). Among the 1,034 subjects who met the NLST criteria, 533 (427 men and 106 women) had a 6-year lung cancer risk ≥2.0%. The combination of these two selection strategies showed that 2.5% of the Spanish population had a high risk of developing lung cancer. However, this selection process did not take into account different groups of subjects <75 years old having an individual risk of lung cancer ≥2%, such as heavy smokers <55 years old who were long-time former smokers, and ever-smokers having smoked <30 pack-years with other risk factors. CONCLUSIONS: Further research is needed to determine which selection strategy achieves a higher benefit/harm ratio and to assess other prevention strategies for individuals with elevated risk for lung cancer but who do not meet the screening eligibility criteria.

Sedentary and Physical Activity Patterns in Adults with Intellectual Disability.

Little is known about the patterns of sedentary time (ST) and physical activity (PA) levels throughout the week among adults and older adults with Intellectual Disability (ID). We analyzed ST and PA patterns of adults and older adults with ID. Forty-two adults and 42 older adults with mild to severe ID participated in this study. Height and weight were obtained to calculate Body Mass Index (BMI). Body fat and fat-free mass percentages were also obtained. Patterns of PA levels and ST were assessed with GT3X Actigraph accelerometers. Adults performed higher amounts of total PA and moderate to vigorous PA than older adults during the week, on weekdays and in center time (all p > 0.05). No differences between males and females were found for either PA levels or ST. Only 10.7% of the participants met the global recommendations on PA for health. The participants of the current study showed low PA levels and a high prevalence of ST. Interestingly, when comparing age and/or sex groups, no differences were observed for ST. Our findings provide novel and valuable information to be considered in future interventions aiming to increase PA levels and reduce ST.

The association between adult attained height and sitting height with mortality in the European Prospective Investigation into Cancer and Nutrition (EPIC).

Adult height and sitting height may reflect genetic and environmental factors, including early life nutrition, physical and social environments. Previous studies have reported divergent associations for height and chronic disease mortality, with positive associations observed for cancer mortality but inverse associations for circulatory disease mortality. Sitting height might be more strongly associated with insulin resistance; however, data on sitting height and mortality is sparse. Using the European Prospective Investigation into Cancer and Nutrition study, a prospective cohort of 409,748 individuals, we examined adult height and sitting height in relation to all-cause and cause-specific mortality. Height was measured in the majority of participants; sitting height was measured in ~253,000 participants. During an average of 12.5 years of follow-up, 29,810 deaths (11,931 from cancer and 7,346 from circulatory disease) were identified. Hazard ratios (HR) with 95% confidence intervals (CI) for death were calculated using multivariable Cox regression within quintiles of height. Height was positively associated with cancer mortality (men: HRQ5 vs. Q1 = 1.11, 95%CI = 1.00-1.24; women: HRQ5 vs. Q1 = 1.17, 95%CI = 1.07-1.28). In contrast, height was inversely associated with circulatory disease mortality (men: HRQ5 vs. Q1 = 0.63, 95%CI = 0.56-0.71; women: HRQ5 vs. Q1 = 0.81, 95%CI = 0.70-0.93). Although sitting height was not associated with cancer mortality, it was inversely associated with circulatory disease (men: HRQ5 vs. Q1 = 0.64, 95%CI = 0.55-0.75; women: HRQ5 vs. Q1 = 0.60, 95%CI = 0.49-0.74) and respiratory disease mortality (men: HRQ5 vs. Q1 = 0.45, 95%CI = 0.28-0.71; women: HRQ5 vs. Q1 = 0.60, 95%CI = 0.40-0.89). We observed opposing effects of height on cancer and circulatory disease mortality. Sitting height was inversely associated with circulatory disease and respiratory disease mortality.

Determination of oleanolic acid in human plasma and its association with olive oil intake in healthy Spanish adults within the EPIC Spain cohort study.

SCOPE: Oleanolic acid (OA) is an important triterpenic compound found in olive oil, however little is known about its concentrations in human plasma. We aimed to determine plasma OA levels in a healthy Spanish population and compare them with estimates of dietary olive oil intake. METHODS AND RESULTS: The final study sample included 141 individuals randomly selected from the European Prospective Investigation into Cancer and Nutrition Spanish cohort. Dietary olive oil intake was estimated using validated dietary history questionnaires. OA concentrations were determined in plasma (from the participants' stored blood samples) using a HPLC-MS method. Correlation coefficients between OA and olive oil intake were calculated, adjusting for center; sex; age; consumption of olives, apples, grapes, and red wine; and fasting state. The mean OA concentration in olive oil nonconsumers was 0.72 ng/mL (SD 0.82), while in the high olive oil intake group it was 1.32 ng/mL (SD 1.14). The fully adjusted partial Spearman correlations coefficients reached 0.36 (p-value < 0.001) overall, varying minimally by sex and fasting state. CONCLUSION: This is the first study providing steady-state concentrations of triterpenes in humans. The results show that there was low-to-moderate correlation between OA concentrations and olive oil intake in this population.

Physical activity and risk of Amyotrophic Lateral Sclerosis in a prospective cohort study.

Previous case-control studies have suggested a possible increased risk of Amyotrophic Lateral Sclerosis (ALS) with physical activity (PA), but this association has never been studied in prospective cohort studies. We therefore assessed the association between PA and risk of death from ALS in the European Prospective Investigation into Cancer and Nutrition. A total of 472,100 individuals were included in the analysis, yielding 219 ALS deaths. At recruitment, information on PA was collected thorough standardised questionnaires. Total PA was expressed by the Cambridge Physical Activity Index (CPAI) and analysed in relation to ALS mortality, using Cox hazard models. Interactions with age, sex, and anthropometric measures were assessed. Total PA was weakly inversely associated with ALS mortality with a borderline statistically significant trend across categories (p = 0.042), with those physically active being 33% less likely to die from ALS compared to those inactive: HR = 0.67 (95% CI 0.42-1.06). Anthropometric measures, sex, and age did not modify the association with CPAI. The present study shows a slightly decreased-not increased like in case-control studies-risk of dying from ALS in those with high levels of total PA at enrolment. This association does not appear confounded by age, gender, anthropometry, smoking, and education. Ours was the first prospective cohort study on ALS and physical activity.
