Cohort profile: The Obesity and Disease Development Sweden (ODDS) study, a pooled cohort.

PURPOSE: The Obesity and Disease Development Sweden (ODDS) study was designed to create a large cohort to study body mass index (BMI), waist circumference (WC) and changes in weight and WC, in relation to morbidity and mortality. PARTICIPANTS: ODDS includes 4 295 859 individuals, 2 165 048 men and 2 130 811 women, in Swedish cohorts and national registers with information on weight assessed once (2 555 098 individuals) or more (1 740 761 individuals), in total constituting 7 733 901 weight assessments at the age of 17-103 years in 1963-2020 (recalled weight as of 1911). Information on WC is available in 152 089 men and 212 658 women, out of whom 108 795 have repeated information on WC (in total 512 273 assessments). Information on morbidity and mortality was retrieved from national registers, with follow-up until the end of 2019-2021, varying between the registers. FINDINGS TO DATE: Among all weight assessments (of which 85% are objectively measured), the median year, age and BMI (IQR) is 1985 (1977-1994) in men and 2001 (1991-2010) in women, age 19 (18-40) years in men and 30 (26-36) years in women and BMI 22.9 (20.9-25.4) kg/m2 in men and 23.2 (21.2-26.1) kg/m2 in women. Normal weight (BMI 18.5-24.9 kg/m2) is present in 67% of assessments in men and 64% in women and obesity (BMI≥30 kg/m2) in 5% of assessments in men and 10% in women. The median (IQR) follow-up time from the first objectively measured or self-reported current weight assessment until emigration, death or end of follow-up is 31.4 (21.8-40.8) years in men and 19.6 (9.3-29.0) years in women. During follow-up, 283 244 men and 123 457 women died. FUTURE PLANS: The large sample size and long follow-up of the ODDS Study will provide robust results on anthropometric measures in relation to risk of common diseases and causes of deaths, and novel findings in subgroups and rarer outcomes.

Twelve-year trends in unprotected left main coronary artery occlusion: insights from a real-world multicentre study.

AIMS: Acute myocardial infarction (AMI) resulting from unprotected left main coronary artery (LMCA) occlusion and subtotal occlusion is a life-threatening condition. Although AMI management has improved in the past two decades, there is limited information on recent trends in patient characteristics, management, and outcomes for acute unprotected LMCA-related AMI. This study aims to assess such trends over a 12 year period. METHODS AND RESULTS: This retrospective multicentre study includes patients with unprotected LMCA occlusion/subtotal occlusion admitted to three tertiary hospitals between 2008 and 2020. The patients were divided into two groups based on the chronology of presentation: a 'past group' (January 2008 to December 2014) and a 'contemporary group' (January 2015 to December 2020). The study compares clinical characteristics, management approaches, and outcomes between the two groups. The study includes 128 patients, with 51 (40%) in the 'past group' and 77 (60%) in the 'contemporary group'. Baseline risk factors did not show statistically significant differences between the two groups, except for hypertension (49% vs. 74%; P = 0.005). Chest pain was more frequent in the 'past group' (98% vs. 89%; P = 0.014), and a trend towards more cardiac arrests was observed in the 'contemporary group' (18% vs. 31%; P = 0.087). Revascularization type did not differ significantly (P = 0.419), but manual thrombectomy was less frequently used (41% vs. 23%; P = 0.032) and stent implantation showed a trend towards higher rates (66% vs. 78%; P = 0.150) in the 'contemporary cohort'. There was a gradual shift from bare-metal to drug-eluting stents, with a significantly higher percentage of ticagrelor/prasugrel loading in the 'contemporary cohort' (5% vs. 79%; P < 0.001). The use of mechanical circulatory support (MCS), although not statistically significant, was higher among patients in the 'past group' (67% vs. 51%; P = 0.073). The type of MCS differed significantly between groups, with a decrease in intra-aortic balloon pump use (67% vs. 42%; P = 0.005) and an increase in veno-arterial extracorporeal membrane oxygenation (4% vs. 22%; P = 0.005) and Impella system (0% vs. 3%) over time. Survival analysis showed no significant differences (P = 0.599; log-rank test) in all-cause mortality between the different time groups, with the long-term survival rate being approximately 30%. CONCLUSIONS: In our real-world population, despite the progressive use of newer drugs and more advanced devices over time, patients with unprotected LMCA occlusion/subtotal occlusion remain a subpopulation with poor prognosis.

Dorsal Lytic Lesions: Cancer or Infection?

Infectious spondylodiscitis is a rare disease and typically presents with an insidious progression characterized by spinal pain that usually starts gradually and progressively worsens over several weeks to months. It occurs through three main mechanisms: direct contamination in cases of trauma or surgery, hematogenous dissemination, or through contiguity. We report the case of a 63-year-old male, admitted due to a history of dorsolumbar pain after falling from a height of 1.5 meters, with four months of evolution, without other accompanying symptoms, and refractory to anti-inflammatory and analgesic therapy. Initial laboratory evaluation revealed normocytic and normochromic anemia and a slight elevation in C-reactive protein. Computed tomography of the spine showed pathological fractures of T7-T9. A percutaneous biopsy was performed, positive for methicillin-sensitive Staphylococcus aureus, and the patient underwent 12 weeks of targeted antibiotic therapy. A surgical procedure with percutaneous posterior arthrodesis from T4 to T12 was performed. With this case, the authors aim to emphasize the importance of biopsy as a complementary diagnostic method to imaging studies in the diagnosis of spondylodiscitis, with the possibility of identifying the causative agent.

From Stress to Sick(le) and Back Again-Oxidative/Antioxidant Mechanisms, Genetic Modulation, and Cerebrovascular Disease in Children with Sickle Cell Anemia.

Sickle cell anemia (SCA) is a genetic disease caused by the homozygosity of the HBB:c.20A>T mutation, which results in the production of hemoglobin S (HbS). In hypoxic conditions, HbS suffers autoxidation and polymerizes inside red blood cells, altering their morphology into a sickle shape, with increased rigidity and fragility. This triggers complex pathophysiological mechanisms, including inflammation, cell adhesion, oxidative stress, and vaso-occlusion, along with metabolic alterations and endocrine complications. SCA is phenotypically heterogeneous due to the modulation of both environmental and genetic factors. Pediatric cerebrovascular disease (CVD), namely ischemic stroke and silent cerebral infarctions, is one of the most impactful manifestations. In this review, we highlight the role of oxidative stress in the pathophysiology of pediatric CVD. Since oxidative stress is an interdependent mechanism in vasculopathy, occurring alongside (or as result of) endothelial dysfunction, cell adhesion, inflammation, chronic hemolysis, ischemia-reperfusion injury, and vaso-occlusion, a brief overview of the main mechanisms involved is included. Moreover, the genetic modulation of CVD in SCA is discussed. The knowledge of the intricate network of altered mechanisms in SCA, and how it is affected by different genetic factors, is fundamental for the identification of potential therapeutic targets, drug development, and patient-specific treatment alternatives.

Acute total occlusion of the unprotected left main coronary artery: Patient characteristics and outcomes.

INTRODUCTION AND OBJECTIVES: Acute total occlusion of the unprotected left main coronary artery (LMCA) is a dramatic event. There are limited data regarding this population. We aimed to describe the clinical presentation and outcomes of patients and to determine predictors of in-hospital mortality. METHODS: This retrospective study included patients presenting with acute (<12 h) myocardial infarction due to total occlusion of the LMCA (TIMI flow 0) between January 2008 and December 2020 in three tertiary hospitals. RESULTS: During this period, 11036 emergent coronary angiographies were performed, 59 (0.5%) of which revealed acute total occlusion of the LMCA. Patients' mean age was 61.2 (SD±12.2) years and 73% were male. No patients had left dominance. At presentation, 73% were in cardiogenic shock, aborted cardiac arrest occurred in 27% and 97% underwent myocardial revascularization. Primary percutaneous coronary intervention was performed in 90% of cases and angiographic success was achieved in 56% of procedures, while 7% of patients underwent surgical revascularization. In-hospital mortality was 58%. Among survivors, 92% and 67% were alive after one and five years, respectively. After multivariate analysis, only cardiogenic shock and angiographic success were independent predictors of in-hospital mortality. Use of mechanical circulatory support and presence of well-developed collateral circulation were not predictive of short-term prognosis. CONCLUSION: Acute total occlusion of the LMCA is associated with a dismal prognosis. Cardiogenic shock and angiographic success play a major role in predicting the prognosis of these patients. The effect of mechanical circulatory support on patient prognosis remains to be determined.

Lidocaine-induced central nervous system toxicity during implantable cardioverter defibrillator placement - A case report and literature review.

Lidocaine, a local anesthetic, is commonly used in various medical procedures. Despite its widespread use, most physicians are not familiar with the life threatening presentation of lidocaine toxicity and its treatment. Our case demonstrates successful management of local lidocaine-induced systemic toxicity in a 53-year-old female during insertion of an implantable cardioverter defibrillator. Our goal was to raise awareness of the risks and symptoms of local anesthetic toxicity, educate regarding the site of administration and dose of anesthetic delivery as independent risk factors for systemic toxicity and highlight the use of intravenous lipid emulsion as an antidote.

Association between classes and subclasses of polyphenol intake and 5-year body weight changes in the EPIC-PANACEA study.

OBJECTIVE: The aim of this study was to evaluate the associations among the intake of total polyphenols, polyphenol classes, and polyphenol subclasses and body weight change over 5 years. METHODS: A total of 349,165 men and women aged 25 to 70 years were recruited in the Physical Activity, Nutrition, Alcohol, Cessation of Smoking, Eating Out of Home and Obesity (PANACEA) project of the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort from nine European countries. Body weight was measured at baseline and at follow-up after a median time of 5 years. Polyphenol intake, including four main polyphenol classes and eighteen subclasses, was estimated using validated dietary questionnaires and Phenol-Explorer. Multilevel mixed linear regression models were used to estimate the associations. RESULTS: Participants gained, on average, 2.6 kg (±5.0 kg) over 5 years. Total flavonoids intake was inversely associated with body weight change (-0.195 kg/5 years, 95% CI: -0.262 to -0.128). However, the intake of total polyphenols (0.205 kg/5 years, 95% CI: 0.138 to 0.272) and intake of hydroxycinnamic acids (0.324 kg/5 years, 95% CI: 0.267 to 0.381) were positively associated with body weight gain. In analyses stratified by coffee consumption, hydroxycinnamic acid intake was positively associated with body weight gain in coffee consumers (0.379 kg/5 years, 95% CI: 0.319 to 0.440), but not in coffee nonconsumers (-0.179 kg/5 years, 95% CI: -0.490 to 0.133). CONCLUSIONS: Higher intakes of flavonoids and their subclasses are inversely associated with a modest body weight change. Results regarding hydroxycinnamic acids in coffee consumers require further investigation.

Dietary Intake of 91 Individual Polyphenols and 5-Year Body Weight Change in the EPIC-PANACEA Cohort.

Polyphenols are bioactive compounds from plants with antioxidant properties that may have a protective role against body weight gain, with adipose tissue and systemic oxidative stress as potential targets. We aimed to investigate the dietary intake of individual polyphenols and their association with 5-year body weight change in a sub-cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC). This study included 349,165 adult participants from nine European countries. Polyphenol intake was estimated through country-specific validated dietary questionnaires and the Phenol-Explorer database. Body weight was obtained at recruitment and after a mean follow-up time of 5 years. Associations were estimated using multilevel mixed linear regression models. From 91 polyphenols included, the majority (n = 67) were inversely associated with 5-year body weight change after FDR-correction (q < 0.05). The greatest inverse associations were observed for quercetin 3-O-rhamnoside (change in weight for doubling in intake: −0.071 (95% CI: −0.085; −0.056) kg/5 years). Only 13 polyphenols showed positive associations with body weight gain, mainly from the subclass hydroxycinnamic acids (HCAs) with coffee as the main dietary source, such as 4-caffeoylquinic acid (0.029 (95% CI: 0.021; 0.038) kg/5 years). Individual polyphenols with fruit, tea, cocoa and whole grain cereals as the main dietary sources may contribute to body weight maintenance in adults. Individual HCAs may have different roles in body weight change depending on their dietary source.

Emerging Marine Biotoxins in European Waters: Potential Risks and Analytical Challenges.

Harmful algal blooms pose a challenge regarding food safety due to their erratic nature and forming circumstances which are yet to be disclosed. The best strategy to protect human consumers is through legislation and monitoring strategies. Global warming and anthropological intervention aided the migration and establishment of emerging toxin producers into Europe's temperate waters, creating a new threat to human public health. The lack of information, standards, and reference materials delay effective solutions, being a matter of urgent resolution. In this work, the recent findings of the presence of emerging azaspiracids, spirolildes, pinnatoxins, gymnodimines, palitoxins, ciguatoxins, brevetoxins, and tetrodotoxins on European Coasts are addressed. The information concerning emerging toxins such as new matrices, locations, and toxicity assays is paramount to set the risk assessment guidelines, regulatory levels, and analytical methodology that would protect the consumers.

Elemental Chemometrics as Tools to Depict Stalked Barnacle (Pollicipes pollicipes) Harvest Locations and Food Safety.

The stalked barnacle Pollicipes pollicipes is an abundant species on the very exposed rocky shore habitats of the Spanish and Portuguese coasts, constituting also an important economical resource, as a seafood item with high commercial value. Twenty-four elements were measured by untargeted total reflection X-ray fluorescence spectroscopy (TXRF) in the edible peduncle of stalked barnacles sampled in six sites along the Portuguese western coast, comprising a total of 90 individuals. The elemental profile of 90 individuals originated from several geographical sites (N = 15 per site), were analysed using several chemometric multivariate approaches (variable in importance partial least square discriminant analysis (VIP-PLS-DA), stepwise linear discriminant analysis (S-LDA), linear discriminant analysis (LDA), random forests (RF) and canonical analysis of principal components (CAP)), to evaluate the ability of each approach to trace the geographical origin of the animals collected. As a suspension feeder, this species introduces a high degree of background noise, leading to a comparatively lower classification of the chemometric approaches based on the complete elemental profile of the peduncle (canonical analysis of principal components and linear discriminant analysis). The application of variable selection approaches such as the VIP-PLS-DA and S-LDA significantly increased the classification accuracy (77.8% and 84.4%, respectively) of the samples according to their harvesting area, while reducing the number of elements needed for this classification, and thus the background noise. Moreover, the selected elements are similar to those selected by other random and non-random approaches, reinforcing the reliability of this selection. This untargeted analytical procedure also allowed to depict the degree of risk, in terms of human consumption of these animals, highlighting the geographical areas where these delicacies presented lower values for critical elements compared to the standard thresholds for human consumption.

VCAM1, HMOX1 and NOS3 differential endothelial expression may impact sickle cell anemia vasculopathy.

Endothelial dysfunction plays a major role in sickle cell anemia (SCA) systemic vasculopathy, with upregulation of adhesion molecules (e.g., VCAM-1), decreased nitric oxide bioavailability, and oxidative stress. We aimed to assess the modulation role of pro-inflammatory and pro-oxidative stimuli on endothelial VCAM1, NOS3, and HMOX1 expression. We also evaluated the effect of the main SCA therapeutic agent, hydroxyurea, on that modulation. Our results showed that two VCAM1 promoter haplotypes, we previously associated with pediatric cerebral vasculopathy and severe hemolysis in SCA, increased promoter activity in TNF-α-stimulated transfected EA.hy926 and HBEC cell lines, consistent with a higher VCAM1 expression in macro and microvascular settings. In non-transfected cells, we also observed TNF-α-induced VCAM1 overexpression as well as heme-induced overexpression of HMOX1 in both cell models. Heme did not affect VCAM1 nor NOS3 expression and the latter was also not affected by TNF-α stimulus. Hydroxyurea treatment lowered TNF-induced VCAM1 and NOS3 expression but did not affect heme-induced HMOX1 expression. These data further indicate that VCAM1 haplotypes we studied lead to higher VCAM1 expression affecting not only cerebral but also systemic vasculopathy risk. The differential endothelial expression of VCAM1, NOS3, and HMOX1 also confirms their genetic modulation role in SCA systemic vasculopathy.

Fighting the pandemic with collaboration at heart: Report from cardiologists in a COVID-19-dedicated Portuguese intensive care unit.

INTRODUCTION AND OBJECTIVES: The coronavirus disease 2019 (COVID-19) spread quickly around the world. Although mainly a respiratory illness, there is growing interest in non-respiratory manifestations, particularly cardiovascular ones. At our center, mobilization of cardiologists with intensive care training was needed. Our aim is to describe patients with severe COVID-19 admitted to a Portuguese intensive care unit (ICU), the cardiovascular impact of the disease and the experience of cardiologists working in a COVID-19 ICU. METHODS: Data from adult patients with COVID-19 admitted to the ICU of Centro Hospitalar de Vila Nova de Gaia/Espinho between 16 March 2020 and 21 April 2020 were analyzed retrospectively. RESULTS: Thirty-five patients were admitted. Mean age was 62.6±6.0 years and 23 (65.7%) were male. Dyslipidemia was the most common cardiovascular risk factor (65.7%, n=23), followed by hypertension (57.1%, n=20). Mean ICU stay time was 15.9±10.0 days. Patients had high rates of mechanical ventilation (88.6%, n=31) and vasopressor support (88.6%, n=31). Low rates of new onset left systolic dysfunction were detected (8.5%, n=2). One patient required venoarterial extra-corporeal membrane oxygenation. Mortality was 25% (n=9). Acute myocardial injury and N-terminal pro-B-type natriuretic peptide (NT-proBNP) elevation was detected in 62.9% (n=22). Patients that died had higher NT-proBNP compared to those discharged alive (p<0.05). Care by cardiologists frequently changed decision making. CONCLUSIONS: The cardiovascular impact of COVID-19 seems relevant but is still widely unknown. Studies are needed to clarify the role of cardiac markers in COVID-19 prognosis. Multidisciplinary care most likely results in improved patient care.

Impella support for cardiogenic shock and high-risk percutaneous coronary intervention: A single-center experience.

INTRODUCTION AND OBJECTIVES: The use of mechanical circulatory support is increasing in cases of cardiogenic shock (CS) and high-risk percutaneous coronary intervention (HR-PCI). The Impella® is a percutaneous ventricular assist device that unloads the left ventricle by ejecting blood to the ascending aorta. We report our center's experience with the use of the Impella® device in these two clinical settings. METHODS: We performed a single-center retrospective study including all consecutive patients implanted with the Impella® between 2007 and 2019 for CS treatment or prophylactic support of HR-PCI. Data on clinical and safety endpoints were collected and analyzed. RESULTS: Twenty-two patients were included: 12 were treated for CS and 10 underwent an HR-PCI procedure. In the CS-treated population, the main cause of CS was acute myocardial infarction (five patients); hemolysis was the most frequent device-related complication (63.7%). In-hospital, cumulative 30-day and one-year mortality were 58.3%, 66.6% and 83.3%, respectively. In the HR-PCI group, all patients had multivessel disease (mean baseline SYNTAX I score: 44.1±13.7). In-hospital, 30-day and one-year mortality were 10.0%, 10.0% and 20.0%, respectively. There were no device- or procedure-related deaths in either group. CONCLUSION: The short- and long-term results of Impella®-supported HR-PCI were comparable to those in the literature. In the CS group, in-hospital and short-term outcomes were poor, with high mortality and non-negligible complication rates.

INTRODUÇÃO E OBJETIVOS: A doença pelo novo coronavirus (COVID-19) espalhou-se rapidamente pelo globo. Embora tenha atingimento essencialmente respiratório, existe interesse nas manifestações extrarrespiratórias, nomeadamente nas cardiovasculares. No nosso centro, foi necessária a mobilização de cardiologistas com experiência em cuidados intensivos para enfrentar este desafio. O objetivo desta investigação é descrever a população internada com COVID-19 grave numa UCI portuguesa, o impacto cardiovascular desta doença e a nossa experiência enquanto cardiologistas numa UCI COVID-19. MÉTODOS: Dados de adultos com COVID-19 internados na UCI do Centro Hospitalar de Vila Nova de Gaia/Espinho entre 16/03/2020 e 21/04/2020 foram analisados retrospetivamente. RESULTADOS: Foram internados 35 doentes. A média de idade foi 62,6±6,0 anos e 23 (65,7%) doentes eram homens. A dislipidemia foi o fator de risco cardiovascular mais prevalente (65,7%, n=23), seguida pela hipertensão (57,1%, n=20). O tempo médio de internamento em UCI foi 15,9±10,0 dias. A necessidade de ventilação mecânica (88,6%, n=31) e suporte vasopressor (88,6%, n=31) foi alta, mas poucos doentes desenvolveram disfunção sistólica de novo (n=2,85%). A mortalidade foi de 25% (n=9). Foi detetada lesão miocárdica aguda e elevação do NT-proBNP em 62,9% (n=22) dos doentes, sendo os níveis de NT-proBNP mais elevados nos doentes que faleceram (p<0,05). A participação de cardiologistas na UCI alterou frequentemente a decisão clínica. CONCLUSÃO: O impacto cardiovascular da COVID-19 parece relevante mas é parcamente conhecido, sendo necessários mais estudos para clarificar o papel dos marcadores cardíacos no prognóstico da COVID-19. As equipas multidisciplinares provavelmente melhoram os cuidados de saúde prestados a estes doentes.

Exploitation of Marine Molecules to Manage Alzheimer's Disease.

Neurodegenerative diseases are sociosanitary challenges of today, as a result of increased average life expectancy, with Alzheimer's disease being one of the most prevalent. This pathology is characterized by brain impairment linked to a neurodegenerative process culminating in cognitive decline and behavioral disorders. Though the etiology of this pathology is still unknown, it is usually associated with the appearance of senile plaques and neurofibrillary tangles. The most used prophylaxis relies on anticholinesterase drugs and NMDA receptor antagonists, whose main action is to relieve symptoms and not to treat or prevent the disease. Currently, the scientific community is gathering efforts to disclose new natural compounds effective against Alzheimer's disease and other neurodegenerative pathologies. Marine natural products have been shown to be promising candidates, and some have been proven to exert a high neuroprotection effect, constituting a large reservoir of potential drugs and nutraceutical agents. The present article attempts to describe the processes of extraction and isolation of bioactive compounds derived from sponges, algae, marine bacteria, invertebrates, crustaceans, and tunicates as drug candidates against AD, with a focus on the success of pharmacological activity in the process of finding new and effective drug compounds.

(De)Politicizing Polyamory: Social Media Comments on Media Representations of Consensual Non-Monogamies.

Our research sits at the intersection of communication studies, sociology, cyberculture, and political philosophy and theory. In 2014, a 10+-min segment on polyamory aired on Portuguese open-access national television, during the prime-time newscast, and was viewed by several million people, according to official reports. The news piece was also advertised and shared online, especially via Facebook, by the network's official page. Moreover, the piece was aired within the context of a segment that celebrated the 40-year anniversary of the 1974 liberal revolution that overthrew the right-wing dictatorial regime that ruled Portugal for more than half of the twentieth century. This context served to frame polyamory (alongside other topics) as explicitly political by presenting them as freedoms seized by that liberal revolution. This study used a mixed-method approach to the analysis of online comments on Facebook made with respect to the referred news piece, by deploying both content analysis and critical discourse analysis to try to understand how the political nature of polyamory is negotiated (affirmed or disavowed), and what ideal of the "political" is mobilized in that negotiation, in connection with other elements of intimate citizenship and modes of systemic discrimination. Through this analysis, we will deepen our understanding of how lay people construe the "political" and the (non-)politicalness of polyamory. It also helps advance contemporary understandings of how polyamory is represented in mainstream media, understood by audiences, and how media-and debates on online social networks-can both amplify and help fight against harmful stereotypes of minorities. Through this research, we contribute to political theory by opening up new ways of conceptualizing the realm of the political as an open-ended definition that must encompass changes in modes of sociality, including a politics of relating as a sub-field, likewise to the study of social movements, and their strategies, around consensual non-monogamies. Overall, results show that the recognition of the validity of polyamory is not the same as the realization that relationship orientation is a political issue in itself and that a privatized mode of understanding politics seems prevalent as well as the default framework used in the comments we analyzed. In addition to that, and as other research has already noted, incivility and hate speech was prevalent in online comments and discussions, further dampening the political potential of dissident modes of existence, especially given that incivility is also deployed by those speaking in favor of Othered identities and experiences.

Preventable fractions of cancer incidence attributable to 7-years weight gain in the Norwegian Women and Cancer (NOWAC) study.

There is a lack of tangible measures for directed public health action to halt the increase in weight and cancer. We estimated the fraction and preventable cases of all and major body fatness-related cancers attributable to 7-years weight gain (≥ 2 kg). We assessed validated self-reported anthropometrics from 44,114 women aged 34-49 years at the enrolment in 1991-1992 and from a second questionnaire in 1998, with follow-up through December 31, 2015. Over 18 years, 3216 body fatness-related cancers and 2041 deaths were reported. Nearly 70% of women experienced weight gain and the average weight change was 4 kg. We observed a substantial proportional impact of weight gain on pancreatic cancer with a population attributable fraction (PAF) of 41.8% (95% CI 8.1-63.1) and a high absolute impact on postmenopausal breast cancer with 4403 preventable cases (95% CI 1064-7299) and a PAF of 16.8% (95% CI 4.1-27.8), and colorectal cancer with 3857 preventable cases (95% CI 1313-5990) and a PAF of 22.6% (95% CI 7.7-35.1). Avoiding weight gain over seven years in middle adulthood could have prevented a considerable proportion of the cancer burden and thousands of cancer cases in women in Norway.
