Objectives: To provide a comprehensive review of the use of electronic patient-reported outcomes measures (ePROs) as digital health tools to assess health-related quality of life (HRQoL) in women with breast, ovarian, cervical, and endometrial cancers., Methods: A systematic review was conducted to identify studies that used ePROs to evaluate HRQoL in women diagnosed with breast and gynecological cancers. The review followed the 2020 update of the PRISMA guidelines and a pre-registered protocol in PROSPERO (CRD42024516737). Inclusion criteria encompassed studies focusing on ePROs for HRQoL assessment in the specified cancers, without language restrictions, and published between January 2000 and December 2023. Studies were retrieved from PubMed, Web of Science, and Scopus. Two reviewers independently screened titles, abstracts, and full texts to identify eligible studies., Results: The search yielded 4978 articles. After removing duplicates, 900 articles were assessed for eligibility by screening the titles and abstracts. After screening the full text of 168 articles, a total of 16 studies were included in this systematic review. These studies were mainly conducted in Europe and the Americas and included different study designs such as randomized controlled trials (four articles), prospective studies (seven articles), and feasibility and validation studies (five articles). The majority of the studies focused on breast cancer (87.5%), with fewer studies addressing ovarian and cervical cancers. A variety of ePRO tools were used, including the FACT and EORTC QLQ. Findings show that ePROs enhance therapeutic management, treatment adherence, and HRQoL through improved symptom monitoring and communication between patients and providers., Conclusion: The integration of ePROs in oncology care facilitates a patient-centered approach, enhances communication between patients and healthcare providers, and supports personalized treatment strategies. These findings underscore the importance of incorporating ePROs into routine cancer care to improve overall patient outcomes and HRQoL., Competing Interests: The authors declared no potential conflicts of interest concerning the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Background: Findings related to the association between persistent organic pollutants (POPs) and gestational diabetes mellitus (GDM) are inconclusive., Objectives: To estimate the strength of the association between POP exposure and GDM in a systematic review with meta-analysis., Search Strategy: MEDLINE, Scopus and Web of Science were searched until July 2023., Selection Criteria: Cohort and case-control studies analysing the association between POPs and GDM., Data Collection and Analysis: We assessed the risk of bias using the Quality in Prognosis Studies scale (QUIPS). Standardised mean differences were pooled using random-effect models., Main Results: Sixteen articles including 12 216 participants were selected. The risk of bias was high in four articles (25%), moderate in 11 (68.75%) and low in one (6.25%). Small mean difference between GDM cases and controls was observed for PFHpA (0.26, 95% confidence interval [CI] 0.1-0.35, I 2  = 0.0%), PCB180 (0.37, 95% CI 0.19-0.56; I 2  = 25.3%), BDE47 (0.23, 95% CI 0.0-0.45, I 2  = 0%), BDE99 (0.36, 95% CI 0.14-0.59; I 2  = 0%), BDE100 (0.42, 95% CI 0.19-0.64; I 2  = 0%) and HCB (0.22, 95% CI 0.01-0.42, I 2  = 39.6%). No considerable difference was observed for the rest of POPs., Conclusion: Small mean differences between GDM cases and controls were observed for some POPs. However, evidence shows mostly moderate quality and results were heterogeneous. Improved research methodology is needed to assess POPs and GDM risk., (© 2023 The Authors.

Objective: To evaluate the effect of replacing 1 h/week of watching television with 1 h/week of light to moderate (LMPA) or vigorous physical activity (VPA) before and during pregnancy on the risk of gestational diabetes mellitus (GDM)., Methods: A case-control study was conducted in pregnant women. Physical activity and television watching before and during pregnancy were assessed using the Paffenbarger Physical Activity Questionnaire. Each type of activity was classified according to intensity (metabolic equivalent of task; MET): less than 6 METs is LMPA, 6 METs or more is VPA. The duration of physical activity and watching television was calculated, and logistic regression models were used to estimate adjusted odds ratios (aOR) and 95% confidence intervals for their association with GDM risk. The isotemporal substitution model was used to calculate the effect of replacing 1 h/week of watching television with the same duration of physical activity., Results: The GDM cases (n = 290) spent less time performing VPA than controls without GDM (n = 1175) and more time watching television during pregnancy (P < 0.05). During pregnancy, the risk of GDM increased for each hour of watching television (aOR = 1.02; 95% confidence interval 1.00-1.03). Women who spent more time watching television during pregnancy were likely to develop GDM (aOR >14 h/week vs. 0-6 h/week  = 2.03; 95% confidence interval 1.35-3.08). Replacing 1 h/week of watching television with 1 h/week of VPA during pregnancy could decrease the chance of developing GDM (aOR = 0.66; 95% confidence interval 0.43-1.00)., Conclusions: A simple change of 1 h/week of watching television for 1 h/week of VPA in pregnant women may reduce the risk of GDM considerably., (© 2023 The Authors.

Acrylamide is a probable carcinogen. Its main sources are the diet and tobacco. The association between acrylamide intake from the diet and tobacco and prostate cancer (PCa) has not been previously evaluated. We aimed to evaluate the relationship between dietary acrylamide intake and exposure to acrylamide through cigarettes and PCa risk. A population-based case-control (CAPLIFE) study was conducted, including 428 incident PCa cases and 393 controls. Smoking and dietary information, with a validated food frequency questionnaire, was collected. We calculated the amount of acrylamide from both sources, and tertiles (Ts) were created. Multivariable logistic regression and restricted cubic spline models were applied to assess the association between exposure to acrylamide and PCa risk. The median was similar for acrylamide in both dietary and smoking acrylamide among PCa cases and controls. No association was observed between dietary acrylamide intake and overall PCa risk (adjusted OR T3vsT1 = 0.90 (95% CI 0.59, 1.37)). A risk trend was observed for acrylamide exposure from cigarette smoking ( p -trend = 0.032), with the highest odds in those subjects with the high exposure to acrylamide through cigarettes (adjusted OR T3vsT1 = 1.67 (95% CI 0.92, 3.04)). The restricted cubic splines suggested a linear relationship. In conclusion, acrylamide from smoking could be positively associated with PCa risk, but no association was observed for dietary acrylamide.

Background: Despite the fact that several studies have investigated the association between serum copper levels (S-Cu) and the risk of cardiovascular diseases, this relationship remains unclear. The aims of this study were to investigate the association between S-Cu and risk of major adverse cardiovascular events (MACE), including total stroke, ischemic stroke, hemorrhagic stroke, myocardial infarction and cardiovascular mortality, and identify potential sources of results heterogeneity., Methods: We carried out a systematic review and meta-analysis. The selection criteria were: (1) Observational studies (cohort studies, case-control studies and hybrid studies); (2) Studies containing quantitative data about the relationship between S-Cu and risk of MACE; (3) Estimating association measures; and (4) Studies written in English, French or Spanish. Overall pooled Odds ratio (pOR) and 95% confidence intervals (95% CI) of MACE for the highest vs. lowest S-Cu category were calculated using random-effects models., Results: Sixteen studies with a total of 41,322 participants were included in the meta-analysis: 10 prospective cohort studies, 5 nested case-control studies and 1 case-control study. Comparing highest vs. lowest category, high S-Cu levels were associated with total stroke (pOR: 1.49, 95% CI 1.22-1.82; I 2  = 0%, p  = 0.54), myocardial infarction (pOR: 1.31, 95% CI 1.17-1.46; I 2  = 0.0%, p  = 0.92) and cardiovascular mortality (pOR: 1.60, 95% CI 1.39-1.86; I 2  = 0.0%, p  = 0.54). Subgroup analysis showed that studies with a hybrid design had higher risks for cardiovascular mortality (pOR: 3.42, 95% CI 1.98-5.92) and ischemic stroke (pOR: 1.54, 95% CI 1.30-1.83)., Conclusion: High S-Cu levels were associated with an increased risk of total stroke, myocardial infarction and cardiovascular mortality. Hybrid studies seems to modify the strength of the association between S-Cu and the risk of cardiovascular mortality and ischemic stroke., Systematic Review Registration: [https://www.crd.york.ac.uk/prospero/display&#95;record.php?ID=CRD42022370782], identifier [CRD42022370782]., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Muñoz-Bravo, Soler-Iborte, Lozano-Lorca, Kouiti, González-Palacios Torres, Barrios-Rodríguez and Jiménez-Moleón.)

Several epidemiological studies stress the association between a diet based on high fruits and vegetables intake and a better health condition. However, elderly Europeans cannot manage the recommended fruits and vegetables consumption. This systematic review aims to explore the main factors related to fruits and vegetables consumption in elderly Europeans. We conducted literature searches on Medline, Scopus, and Web of Science from inception to May 2022. Published articles including data related to certain fruits and vegetables consumption among elderly Europeans were selected. The New Castle-Ottawa Scale and National Heart, Lung, and Blood Institute tools were used for methodological quality assessment by two authors independently. A total of 60 articles were retrieved, and data from twenty-one high-quality cross-sectional studies and five moderate-to-high-quality cohort studies, including a total of 109,516 participants, were synthesized. Associated factors mostly analyzed were those relating to demographic and socioeconomic status, such as sex, age, marital status, educational level, and income. However, the findings show a high discrepancy. Some evidence suggests a possible positive association, while other evidence shows an inverse or no association at all. The relationship between demographic and socioeconomic factors with fruits and vegetables consumption is not at all clear. More epidemiological studies with an appropriate design and corresponding statistical methods are required.

Several epidemiological studies have analyzed the effects of lifestyle modification on reducing the risk of gestational diabetes mellitus (GDM); however, their results remain inconsistent. This umbrella review aims to evaluate the effects of diet and/or physical activity interventions during pregnancy on preventing GDM. Systematic reviews and meta-analysis of randomized clinical trials reporting preventive effects of diet and/or physical activity in reducing the incidence of GDM were included from PubMed, Web of Science, Scopus and Cochrane library. Two authors independently assessed the overlapping and quality of the 35 selected reviews using AMSTAR 2. The results, although variable, tend to defend the protective role of diet and physical activity interventions separately and independently of each other in the prevention of GDM. However, the results for the combined interventions show a possible protective effect; however, it is not entirely clear because most of the analyzed meta-analyses tend to approach 1, and heterogeneity cannot be ruled out. Establishing conclusions about the most efficient type of intervention and a dose-effect relationship was not feasible given the low quality of systematic reviews (83% low to critically low) and the variability in reporting interventions. Therefore, more studies with better quality and definition of the interventions are required. The protocol was previously registered in PROSPERO as CRD42021237895.
