This study aimed to determine whether pupils who have breakfast just before a cognitive demand, do not regularly skip breakfast, and consume a high-quality breakfast present higher cognitive performance than those who do not; furthermore, to establish differences according to their nutritional status. In this study, 1181 Chilean adolescents aged 10–14 years participated. A global cognitive score was computed through eight tasks, and the body mass index z-score (BMIz) was calculated using a growth reference for school-aged adolescents. The characteristics of breakfast were self-reported. Analyses of covariance were performed to determine differences in cognitive performance according to BMIz groups adjusted to sex, peak height velocity, physical fitness global score, and their schools. A positive association was found in adolescents’ cognitive performance when they had breakfast just before cognitive tasks, did not regularly skip breakfast, presented at least two breakfast quality components, and included dairy products. No significant differences were found between breakfast components, including cereal/bread and fruits/fruit juice. Finally, pupils who were overweight/obese who declared that they skipped breakfast regularly presented a lower cognitive performance than their normal-BMIz peers. These findings suggest that adolescents who have breakfast just prior to a cognitive demand and regularly have a high quality breakfast have better cognitive performance than those who do not. Educative nutritional strategies should be prioritized, especially in “breakfast skippers” adolescents living with overweight/obesity.  相似文献

IntroductionWe aimed to evaluate the success of bladder neck injections of triamcinolone at the time of transurethral bladder neck incision (BNI) for prevention of recurrent vesicourethral anastomotic stenosis (VUAS) following prostate cancer treatment.MethodsThis is a retrospective cohort study examining patients with recurrent VUAS post-radical prostatectomy (RP) ± radiation treated with triamcinolone injections at the time of BNI. VUAS was diagnosed by symptoms followed by cystoscopy or urethrography. The outpatient procedures were done under general anesthesia. Cold knife incisions were made at the three, nine, and 12 o’clock BN positions, followed by triamcinolone injections (4 mg/mL) into the three and nine o’clock incision sites. Treatment outcomes were determined with cystoscopy.ResultsEighteen men underwent 25 procedures over a four-year period. Median age at diagnosis of VUAS was 65 (interquartile range [IQR] 61–68); median time to VUAS from RP was eight months (IQR 5–12). Fourteen patients (78%) had radiation treatment. The cohort had 128 unsuccessful VUAS treatments, with a median of five failed treatments per patient (IQR 3–10). Failed treatments included BN dilation, BNI, BN injection of mitomycin C, and urethral stent placement. Success rate after a mean of 16.3 months (standard deviation [SD] 8.1) from the time of triamcinolone injection was 83% (15/18). Six patients went on to have successful incontinence surgery. Five patients (28%) had treatment complications (bleeding, urinary tract infection, pain, and urinary extravasation). The three non-responders are stable and awaiting re-treatment with triamcinolone injection.ConclusionsTriamcinolone bladder neck injections for post-RP VUAS are a useful and safe treatment for recurrent stenosis.  相似文献

BackgroundPenile prostheses are the third option in the treatment of erectile dysfunction, however, despite their proven effectiveness, the occurrence of infections, advanced age of patients and comorbidities are the main limiting factors for this treatment modality. In the continuous search for biointegrated, clinically durable and minimally invasive treatment options, a possible model of penile prosthesis was sought through the use of intracavernous bacterial cellulose (BC) gel, in an experimental model of orchiectomized rabbits.MethodsThirty adult New Zealand rabbits were equally distributed into three groups: BC; vehicle and control. Each group was then subdivided according to the follow-up time of 3 and 6 months. Bilateral orchiectomy was performed 3 weeks before injection in the BC and vehicle groups. Pachymetry measurements of the penile axis, diameter and length were performed in situ. Histomorphometry analyzes of the corpora cavernosa (CC), thickness of the tunica albuginea, cell density, collagen and elastic fibers post-injection were also performed, in addition to immunohistochemistry for newly formed vessels.ResultsThe implant of BC increased both the length and thickness of the penis three and six months after the last injection, with a consequent increase in the diameter of the CC. On the other hand, the filling effect was not observed in the control and vehicle groups, confirming the degradation of this tissue after orchiectomy and the effectiveness of BC as a filling agent. Histomorphometry analyzes corroborate the mass effect of BC integrated into the tissue, permeated by predominantly lymphomononuclear inflammatory infiltrate, multinucleated giant foreign body cells, fibroblasts, elastic fibers and newly formed vessels, without degradation or loss of volume, even after six months of implantation.ConclusionsBiocompatibility and biointegration to the host tissue make BC a prosperous penile filling material, with local application and minimally invasive.  相似文献

Increasingly, patients of advanced age are coming for evaluation of periampullary tumors. Although several studies have demonstrated the safety of resecting periampullary tumors in older patients, few long-term survival data have been reported. Between 1983 and 1992 various periampullary masses were resected in 70 patients over age 65 (range 65–87 years). Total pancreatectomy was performed in 11 patients, and 59 patients underwent pancreaticoduodenectomy. The mean duration of hospitalization was 17 ± 15 days. Major complications occurred in 27 patients (39%), and operative mortality rate was 8.5%. Overall median survival was 24 months; and 5-year survival was 25%. Perioperative outcome was compared in patients aged 65 to 74 years and in patients ≥75 years old. The older age group required longer periods in the surgical intensive care unit postoperatively, but the long-term survival was similar in the two age groups. Radical resection with the intent to cure periampullary tumors is safe in selected patients of advanced age, and long-term survival is in the range of expected survival for younger patients with the same tumors.  相似文献

OBJECTIVE: To study the patterns and determinants of psychoactive drug use by Lisbon University students. MATERIALS AND METHODS: A cross-sectional survey was conducted, from January to April 2000, in a probabilistic sample of 1,147 students. Information about use of psychoactive drugs and co-variates was collected by a questionnaire administered by trained interviewers. Psychoactive drugs were considered to be all medicines classified in group N (nervous system) of the ATC system except the anesthetics (subgroup N01) and the analgesics (subgroup N02). RESULTS: 91 students (7.9%) had taken psychoactive drugs during the fortnight before the interview, 39 of whom (42.8%) mentioned continuous use. The prevalence of use was significantly higher in females (9.6%), older than 25 years (13.1%), married (16%), who considered themselves to have a weak health status (21.7%), as under intense stress (15.5%). After adjustment by multivariate analysis the variables sex, self-evaluation of health status and daily stress retained a higher significant association with psychoactive drug use. A total of 132 drugs were reported as being used in that period. Tranquilizers (ATC = N05B or N05C) were used by 82 students (7.2%), while 22 (1.9%) consumed psychoactive stimulants (N06B) and 19 (1.7%) antidepressants (N06A). In all of these therapeutical subgroups, females had higher consumption prevalence than males, but the difference was statistically significant only for tranquilizers (P < 0.001). Anxiety, depression and insomnia were the most frequently stated health problems. More than 90% of drug consumers considered they had a compliant attitude and about 60% considered themselves well-informed about adverse effects of the drug used. The reported prevalence of self-medication for psychoactive drugs used was 12.8%. CONCLUSIONS: The prevalence of psychoactive drug use among students of Lisbon University was higher than expected, considering age group and the usual health status of this population. The administration of a questionnaire was a very useful tool to characterise the pattern of use and the consumer's knowledge about the drugs consumed.  相似文献

We present a small child with febrile peaks and syncopal episodes secundary to ventricular tachycardia, in whom it was eventually possible to demostrate the Brugada Syndrome with a special presentation in the ECG; early repolarization pattern in lead I and a aVL and Brugada pattern during fever in V1‐V2. This is, to our knowledge, tha first case with this special ECG presentation in a small child.  相似文献

Toxocara spp. infection and the seroconversion rate in the Amazon have been poorly investigated. This study analyzed individual and household-level risk factors for the presence of IgG antibodies to Toxocara spp. in urban Amazonian children over a period of 7 years and evaluated the seroconversion rates over a 1-year follow-up. In children < 59 months of age, the overall prevalence rate was 28.08% in 2003 and 23.35% in 2010. The 2010–2011 seroconversion rates were 13.90% for children 6–59 months of age and 12.30% for children 84–143 months of age. Multilevel logistic regression analysis identified child age, previous wheezing, and current infection with hookworm as significant associated factors for Toxocara spp. seropositivity in 2003. In 2010, age, previous helminthiasis, and having a dog were associated with seropositivity, whereas having piped water inside the household was a protective factor. Control programs mainly need to target at-risk children, water quality control, and animal deworming strategies.  相似文献
