Consumption of aspartame and other artificial sweeteners and risk of cancer in the Spanish multicase-control study (MCC-Spain).

Use of artificial sweeteners (AS) such as aspartame, cyclamate, saccharin and sucralose is widespread. We evaluated the association of use of aspartame and other AS with cancer. In total 1881 colorectal, 1510 breast, 972 prostate and 351 stomach cancer and 109 chronic lymphocytic leukaemia (CLL) cases and 3629 population controls from the Spanish Multicase-Control (MCC-Spain) study were recruited (2008-2013). The consumption of AS, from table-top sweeteners and artificially sweetened beverages, was assessed through a self-administered and validated food frequency questionnaire (FFQ). Sex-specific quartiles among controls were determined to compare moderate consumers (

Excess Weight in Relation to Lifestyle Habits in Spanish First-Year University Students: Differences between Pre- and Post-COVID-19-A Serial Cross-Sectional Study Based on uniHcos Project.

The objective of this research was to study the relationship between the body weight and diet, physical activity, and other habits among freshmen students by sex, and to determine whether these habits have changed during the post-era of the COVID-19 pandemic. A serial cross-sectional study with data from 11 Spanish universities was carried out. In total, 10,096 first-year university students (73.2% female, mean age = 19.0 ± 1.5 years) completed an online self-administered questionnaire between 2012 and 2022. For some analyses, questionnaires were categorized by the year in which the survey was filled out as Before COVID-19, Lockdown, and New Normal. In total, 72.9% of participants were within the normal weight range, and 17.7% of men and 11.8% of women were overweight (p < 0.001). The students who did not meet the WHO criteria of physical activity, spent more than 7 h per day sitting, and skipped breakfast had a higher prevalence of obesity (p < 0.05). According to the period of study, the prevalence of overweight/obesity Before COVID-19 was 16.1% (95% CI: 15.4-16.9%), while in Lockdown the prevalence was significantly higher (20.2, 95% CI: 17.1-23.8) and in New Normal it was 18.9% (CI: 15.7-22.5). Moreover, the study suggests that during the Lockdown period, there was a reduction in the practice of physical activity and an increase in the prevalence of a healthy diet. For all these, it is necessary to propose public health interventions that improve the lifestyles of university students.

Prevalence of Depression and Fish Consumption among First Year Spanish University Students: UniHcos Project.

The World Health Organization estimates that one fifth of university students have experienced major depressive disorder at some point in their lives. Nutrition may be one of the modifiable factors that influence the development of depression. Specifically, low omega-3 fatty acid and vitamin D levels, both nutrients found in high quantities in fish, have been linked to depressive disorders. The main objective of this study was to evaluate the prevalence of depression among young Spanish university students, in addition to the pattern of fish consumption among students and the possible relationship between fish consumption and the presence of depression. Data were collected retrospectively from a nationally representative sample of 11,485 Spanish university students aged 18 years or older in 11 Spanish universities, from 2012 to 2022. The respondents were analyzed according to frequency of consumption and compliance with weekly recommendations for fish intake and the presence of depression. Regression models were also performed to determine students' odds of depression as a function of compliance with recommendations according to selected sociodemographic variables. The prevalence of depression was 10.5%; it was more prevalent in women, older students and in those with both high and low BMIs. In addition, it was also more prevalent in those that lived outside the family home, with roommates and those who were employed. Sixty-seven percent of the students met the fish intake recommendations. The most common frequency of fish consumption was 1-2 times/week (44.2%), and the least frequent was 2.3% daily fish consumption. Students from northern universities were more likely to consume fish (68.4%) than those from southern universities (66.4%). Non-consumption of fish was found to increase the risk of depression (ORa = 1.45 (1.28-1.64); AF = 31.0% (21.9-39.0)), but it was the student's own conditions that had the greatest influence on the development of the disorder. In summary, a lower consumption of fish seems to be associated with a higher incidence of depression in Spanish university students; however, other social factors of the student may influence the development of the disorder, and all of this should be taken into account for the development of prevention strategies.

Association of occupational heat exposure and colorectal cancer in the MCC-Spain study.

OBJECTIVE: Heat exposure and heat stress/strain is a concern for many workers. There is increasing interest in potential chronic health effects of occupational heat exposure, including cancer risk. We examined potential associations of occupational heat exposure and colorectal cancer (CRC) risk in a large Spanish multi-case--control study. METHODS: We analyzed data on 1198 histologically confirmed CRC cases and 2690 frequency-matched controls. The Spanish job-exposure matrix, MatEmEsp, was used to assign heat exposure estimates to the lifetime occupations of participants. Three exposure indices were assessed: ever versus never exposed, cumulative exposure and duration (years). We estimated odds ratios (OR) and 95% confidence intervals (CI) using unconditional logistic regression adjusting for potential confounders. RESULTS: Overall, there was no association of ever, compared with never, occupational heat exposure and CRC (OR 1.09, 95% CI 0.92-1.29). There were also no associations observed according to categories of cumulative exposure or duration, and there was no evidence for a trend. There was no clear association of ever occupational heat exposure and CRC in analysis conducted among either men or women when analyzed separately. Positive associations were observed among women in the highest categories of cumulative exposure (OR 1.81, 95% CI 1.09-3.03) and duration (OR 2.89, 95% CI 1.50-5.59) as well as some evidence for a trend (P<0.05). CONCLUSION: Overall, this study provides no clear evidence for an association between occupational heat exposure and CRC.

A new look into uveitis in Colombia: changes in distribution patterns and clinical characteristics over the last 25 years.

PURPOSE: To describe the distribution patterns and clinical characteristics of patients diagnosed with uveitis at a specialized uveitis center in Bogotá, Colombia, from 2013 to 2021 and compare these patterns with the previously reported between 1996 and 2006. METHODS: We performed an observational descriptive cross-sectional study systematically reviewing clinical records of patients attending between 2013 and 2021. Data were analyzed and compared with previous reports. RESULTS: Of the 489 patients with uveitis, 310 were females (63.4%). The mean age of onset was 38.7, with a range between 1 and 83 years. Bilateral (52.8%), anterior (45.8%), non-granulomatous (90.8%), and recurrent (47.6%) were the most common types of uveitis found in our population sample. The most common cause of uveitis in this study was idiopathic, followed by toxoplasmosis and HLA-B27 + associated uveitis, which differs from the previous Colombian study where ocular toxoplasmosis was the most frequent cause. This highlights a significant shift from infectious etiologies to more immune-mediated processes as the cause of uveitis in Colombia nowadays. CONCLUSION: The results of this study provide a comparison between the clinical patterns of presentation of uveitis from 1996 to 2006 and the patterns observed from 2013 to 2021, enhancing awareness about the changing dynamics of uveitis in Colombia to guide a better understanding of the diagnosis, classification, and correlation with other systemic conditions of the disease.

Health-Related Quality of Life (HRQOL) Instruments and Mobility: A Systematic Review.

Physical function is one of the most important constructs assessed in health-related quality of life (HRQOL), and it could be very useful to assess movement ability from the perspective of the patient. The objective of this study was to compare the content of the domains related to mobility covered by the HRQOL questionnaires based on the International Classification of Functioning, Disability and Health (ICF) and to evaluate their quality according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidance. For this, a systematic review was carried out in the databases Scopus, Web of Science and Science Direct. The inclusion criteria were development and/or validation studies about generic HRQOL measures, and the instruments had to include items related to mobility and studies written in English or Spanish. The comparison of content was performed using the ICF coding system. A total of 3614 articles were found, 20 generic HRQOL instruments were identified and 120 (22.4%) mobility-related items were found. Walking was the most represented category. Low-quality evidence on some measurement properties of the generic HRQOL instruments was revealed. The CAT-Health is a useful questionnaire to be used in rehabilitation due to its psychometric properties and its content.

Prognostic implication of TERT promoter mutation and circulating tumor cells in muscle-invasive bladder cancer.

PURPOSE: Current clinical prognostic factors are not accurate enough to identify and monitor those muscle-invasive bladder cancer (MIBC) patients at high risk of progression after radical cystectomy (RC). Here, we determined genetic alterations in the tumor and circulating tumor cell (CTC) enumeration to find biomarkers useful for the management of MIBC after RC. METHODS: Thirty-nine MIBC patients undergoing RC were included. Tumoral tissue DNA was analyzed by next generation sequencing. CTCs were isolated from blood collected before RC and one, four and 12 months later. RESULTS: Sixteen (41%) patients progressed in a median time of 8.5 months and 11 (69%) of these patients harbored the TERT c.-124C > T mutation. All progressive patients harboring the TERT c.-124C > T mutation presented a significant increase in CTC number 12 months after RC compared to those without the mutation. Additionally, CTC number at 12 months was identified as an independent prognostic biomarker for tumor progression and cancer specific survival (CSS). Ten (63%) progressive patients showed an increment of CTC number with a median anticipation period of four months compared with imaging techniques. CONCLUSIONS: The TERT c.-124C > T mutation could be considered a biomarker of aggressivity. CTC enumeration is a useful tool for identifying MIBC patients at high risk of progression and CSS after RC and for detecting tumor progression earlier than imaging techniques.

Single sagittal craniosynostosis surgical treatment with the "Peau d́ours" technique. Single-center experience in Mexico.

Scaphocephaly (SC) is defined as an elongation of the anteroposterior axis of the skull resulting from the abnormal fusion of the sagittal suture. This study describes the "Peau d'ours" technique and results for correcting SC. We conducted a consecutive and retrospective analysis of patients treated from 2011 to 2016. We evaluated the gender, age, and surgical outcomes. A total of 53 patients were enrolled with a mean age of 19 months old. The advantages of this technique are healthy coronal and lambdoid suture preservation and symmetrical parietal bone flap opening. This technique is safe and simple to reproduce, allowing good surgical outcomes with a low incidence of secondary craniosynostosis. This technique is ideal for patients older than six months old.

Severe sequelae in bilateral acute iris transillumination syndrome secondary to the use of oral moxifloxacin: a case report.

BACKGROUND: Moxifloxacin is a fourth-generation fluoroquinolone used as a second-line treatment for multiple bacterial infections. Uveitis has been described as an adverse effect related to this medication. Although several case reports have been published describing uveitis and bilateral acute iris transillumination syndrome related to moxifloxacin, we present a unique case of a patient with severe sequelae associated with bilateral acute iris transillumination syndrome secondary to the use of oral moxifloxacin. CASE PRESENTATION: A 45-year-old Colombian hispanic female presented bilateral conjunctival hyperemia, decreased visual acuity, blurred vision, photophobia, and ocular pain after 15 days of treatment with systemic moxifloxacin for an upper tract respiratory infection. The patient presented unilateral anterior chamber pigment dispersion, mydriatic and nonreactive pupils, extensive iris transillumination defects, and secondary glaucoma. Blood and aqueous humor tests were negative for infectious and autoimmune diseases. Moxifloxacin-induced bilateral acute iris transillumination syndrome was diagnosed. Permanent sequelae such as ocular pain, photophobia, and focus difficulty secondary to severe bilateral iridian atrophy and inability of synkinetic reflex were left. Additionally, glaucoma was diagnosed, and Ahmed valve implantation was required. CONCLUSIONS: We should be aware of the possible association between moxifloxacin and bilateral acute iris transillumination syndrome. A detailed anamnesis, adequate examination, and laboratory tests are necessary to reach an early diagnosis and treatment to avoid unnecessary therapies. Larger studies should be carried out to understand the pathophysiology, diagnosis, management, and sequelae of the disease.

Sleep duration and napping in relation to colorectal and gastric cancer in the MCC-Spain study.

Sleep duration is a novel and potentially modifiable risk factor for cancer. We evaluated the association of self-reported sleep duration and daytime napping with odds of colorectal and gastric cancer. We included 2008 incident colorectal cancer cases, 542 gastric cancer cases and 3622 frequency-matched population controls, recruited in the MCC-Spain case-control study (2008-2013). Sleep information, socio-demographic and lifestyle characteristics were obtained through personal interviews. Multivariable adjusted logistic regression models were used to estimate odds ratios (OR) with 95% confidence intervals (CI) for cancer, across categories of sleep duration (≤ 5, 6, 7, 8, ≥ 9 hours/day), daytime napping frequency (naps/week) and duration (minutes/nap). Compared to 7 hours of sleep, long sleep was associated with increased odds of colorectal (OR≥9 hours: 1.59; 95%CI 1.30-1.94) and gastric cancer (OR≥9 hours: 1.95; 1.37-2.76); short sleep was associated with increased odds of gastric cancer (OR≤5 hours: 1.32; 0.93-1.88). Frequent and long daytime naps increased the odds of colorectal (OR6-7 naps/week, ≥30 min: 1.32; 1.14-1.54) and gastric cancer (OR6-7 naps/week, ≥30 min: 1.56; 1.21-2.02). Effects of short sleep and frequent long naps were stronger among participants with night shift-work history. Sleep and circadian disruption may jointly play a role in the etiology of colorectal and gastric cancer.

The Effect of Lifestyle Intervention on Health-Related Quality of Life in Adults with Metabolic Syndrome: A Meta-Analysis.

The aim of this meta-analysis was to assess the effects of a lifestyle intervention through health education on nutrition, physical activity, and healthy habits on physical and mental health-related quality of life (HRQoL), in adults with metabolic syndrome (MetS). The databases used were PubMed, WOS, and Scopus. The inclusion criteria were: observational, longitudinal and randomized clinical trial (RCT) study designs, adults (both sexes), with at least two criteria of MetS, lifestyle intervention and comparison with a control group, and a measurement of HRQoL with a validated questionnaire. We analyzed the Hedges' g and SF-36 score. I2 statistics were calculated and possible publication and small study biases were assessed using Egger's test and funnel plots. Seven RCTs were selected for meta-analysis, based on 637 study participants. Significant improvements were found in the physical dimensions of the HRQoL scores for subjects in the active intervention compared to the group that received general lifestyle information (Hedges' g 0.61, 95% confidence interval (CI) = 0.31-0.91). Mental health-related quality of life was also significantly improved in the intervention group compared with the control group (Hedges' g 0.84, 95% CI = 0.64-1.03). In conclusion, our results suggest that, according to the RCTs selected for this meta-analysis, a lifestyle intervention significantly improves HRQoL in all its domains.

Effects of resective epilepsy surgery on the social determinants of health.

OBJECTIVES: The aim of this study is to analyze changes in the Social Determinants of Health (SDH) in patients undergoing epilepsy surgery in Mexico. MATERIALS AND METHODS: We retrospectively analyzed 102 adult patients who underwent brain resection for focal epilepsy (2002-2014) with at least 4 years of follow-up; described clinical variables (age, race, sex, age of onset of epilepsy, age at the time of surgery, type of surgery, side of surgery) and sociodemographic variables including education, income, race/ethnicity, occupation, and marital status. STATISTICAL ANALYSIS: Descriptive and inferential statistics were used. RESULTS: 54.9% (56) of the participants were women, with a mean age of 38.2 (±9.6) years at the time of the survey. The average and mean duration of drug-resistant epilepsy before surgery after diagnosis was 19.6 (±9.3) years; 77.9% (77) had temporal lobe surgeries and 24.5% (25) had extra-temporal lobe surgeries; 80.4% (82) and 19.6% (20) of patients were classified as Engel I and Engel II, respectively, with at least 4 years of postoperative follow-up. Education level (26.9%, p=<0.001), employment rate (4.9%, p= <0.001), and income (9.8%, p = 0.024) increased after surgery; 20.5% of patients were married after surgery. CONCLUSIONS: Following focal resective epilepsy surgery there was a significant increase in the education level, financial income and employment at 4 years' postoperative follow-up.

Electrocorticographic Patterns in Epilepsy Surgery and Long-Term Outcome.

PURPOSE: The role of intraoperative electrocorticography (iECoG) and of its patterns in epilepsy surgery have shown contradictory results. Our aim was to describe iECoG patterns and their association with outcome in epilepsy surgery. METHODS: We retrospectively analyzed 104 patients who underwent epilepsy surgery (2009-2015) with pre- and postresection iECoG. We described clinical findings, type of surgery, preresection iECoG patterns according to Palmini et al., 1995 (sporadic, continuous, burst, and recruiting interictal epileptiform discharges-IEDs) and postresection iECoG outcome (de novo, residual, and without IEDs). The Engel scale was used to evaluate the outcome. Descriptive statistics, Kaplan-Meier, the logistic regression model, and analysis of variance tests were used. RESULTS: We included 60.6% (63/104) females, with a mean age of 35 (±10.2) years at the time of epilepsy surgery. The etiologies were hippocampal sclerosis (63.5%), cavernomas (14.4%), cortical dysplasia (11.5%), and low-grade tumors (10.6%). The most common preresection iECoG pattern was sporadic IEDs (47%). Postresection iECoG patterns were de novo (55.7%), residual (27.8%), and without IEDs (16.3%). Mean follow-up was 19.2 months. Engel scale was as follows: Engel I (91 patients, 87.5%), Engel II (10 patients, 9.6%), and Engel III (three patients, 2.9%). Analysis by mixed-design analysis of variance showed a significant difference between etiology groups with a strong size effect (P = 0.021, η = 0.513) and also between preresection iECoG patterns (P = 0.008, η = 0.661). CONCLUSIONS: Preresection iECoG patterns and etiology influence Engel scale outcome in lesional epilepsy surgery.
