Quantitative and Qualitative Changes in Diet Associated with the Consumption of Ultra-Processed Foods: A Survey on a Representative Sample of Manufacturing Workers in Brazil.

The increasing intake of ultra-processed (UP) foods is causing changes in the profile of food and nutrient consumption, negatively influencing consumer behavior. The present study aimed to evaluate the influence of UP foods on the diet of Brazilian adults, verifying the association between its increasing contribution to total energy and trends in the consumption of other NOVA groups, food subgroups, energy consumption, and macro- and micronutrients. We conducted an observational, cross-sectional study of a probability sample of 921 manufacturing workers in the state of Rio Grande do Norte, Brazil, from a combined stratified and two-stage survey. Trends in consumption across quintiles of UP food contribution to the total energy intake were tested with linear regression. The results showed that higher UP food consumption is associated with a higher intake of energy, carbohydrates and total-, mono- and polyunsaturated fats, saturated fats and trans fats, and the micronutrients calcium, iron and thiamine; and higher consumption of ready-to-eat foods, accompanied by lower consumption of foods that require preparation, such as beans, tubers and roots, vegetables and fruits, which may represent a risk for the development of non-transmissible chronic diseases in this population.

Cerebral venous drainage in patients with dural arteriovenous fistulas: correlation with clinical presentation.

OBJECTIVE: Dural arteriovenous fistulas (DAVFs) are abnormal, acquired arteriovenous connections within the dural leaflets. Their associated symptoms may be mild or severe and are related to the patient's venous anatomy. With the hypothesis that the patient's venous anatomy determines the development of symptoms, the authors aimed to identify which venous anatomy elements are important in the development of major symptoms in patients with a DAVF. METHODS: A multicenter study was performed based on the retrospective analysis of cerebral angiographies with systematic assessment of brain drainage pathways (including fistula drainage) in patients over 18 years of age with a single DAVF. The patients were divided into two groups: those with minor (group 1, n = 112) and those with major (group 2, n = 89) symptoms. Group 2 was subdivided into two groups: patients with hemorrhage (group 2a, n = 47) and patients with severe nonhemorrhagic symptoms (group 2b, n = 42). RESULTS: The prevalence of stenosis in DAVF venous drainage and the identification of tiny anastomoses between venous territories were significantly higher in group 2 (32.6% and 19.1%, respectively) compared with group 1 (2.68% and 5.36%, respectively). Stenosis of DAVF venous drainage was significantly more frequent in group 2a than in group 2b (51.1% vs 11.9%, p < 0.001). Group 2b patients had increased prevalence of shared use of the cerebral main drainage pathway (85.0% vs 53.2%, p = 0.002), the absence of an alternative route (45.0% vs 17.0%, p = 0.004), and the presence of contrast stagnation (62.5% vs 29.8%, p = 0.002) compared with group 2a patients. In patients with high-grade fistulas, the group with major symptoms had increased prevalence of a single draining direction (31.3% vs 8.33%, p = 0.003), stenosis in the draining vein (35.0% vs 6.25%, p = 0.000), the absence of an alternative pathway for brain drainage (31.3% vs 12.5%, p = 0.017), and the presence of contrast stagnation (48.8% vs 22.9%, p = 0.004). CONCLUSIONS: Major symptoms were observed when normal brain tissue venous drainage was impaired by competition with DAVF (predominance in group 2b) or when DAVF venous drainage had anatomical characteristics that hindered drainage, with consequent venous hypertension on the venous side of the DAVF (predominance in group 2a). The same findings were observed when comparing two groups of patients with high-grade lesions: those with major versus those with minor symptoms.

Repeat Prostatic Artery Embolization for Patients with Benign Prostatic Hyperplasia.

PURPOSE: To evaluate the safety and efficacy of repeat prostatic artery (PA) embolization (PAE) for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: A single-center retrospective study was conducted from 2009 to 2018 in 108 patients with symptomatic BPH treated with repeat PAE: group A (n = 39; 36.1%) were patients who never showed a response to PAE, and group B (n = 69; 63.9%) were patients who had clinical improvement in the first 6 months following PAE but relapsing symptoms afterward. The main patterns of revascularization were 75% from the previously embolized PA and 25% from collateral vessels (superior vesical, posterior-lateral PA, penile branches). Technical outcomes and adverse events were registered. International Prostate Symptom Score (IPSS), quality of life (QOL), and clinical success were compared between groups. RESULTS: Median follow-up was 18 months (range, 1-36 mo); median interval between PAE and repeat PAE was 420 days (range, 77-2,240 d). Mean procedural time was significantly longer for repeat PAE vs initial PAE (81.1 min vs 67.4 min; P = .0007). There were no major complications and no urinary incontinence. Mean IPSS/QOL improvements were greater in group B vs group A: 9.51 vs 6.13 and 1.30 vs 0.56, respectively (P < .001). The cumulative probability of clinical success after repeat PAE was higher in group B than in group A (P = .0001): 84.1% vs 46.2% at 1 month, 56.7% vs 28.2% at 12 months, and 51.9% vs 16.9% at 24-36 months. CONCLUSIONS: Repeat PAE is safe and effective for recurrence of lower urinary tract symptoms caused by BPH but has limited impact in patients who did not show a response to initial PAE.

Relationships between Motivations for Food Choices and Consumption of Food Groups: A Prospective Cross-Sectional Survey in Manufacturing Workers in Brazil.

Motivations for food choices may determine consumption, and understanding that relationship may help direct strategies for formulating diets. This study aimed to identify associations between motivations for food choices and consumption of food groups. An observational cross-sectional survey was conducted in 921 manufacturing workers from 33 companies in Brazil, based on a stratified two-stage probability sample. Motivations for food choices were assessed with the Food Choice Questionnaire, and intake of food groups was measured using 24-h dietary recall. Consumption was classified into 31 food groups defined according to their nutritional value and the NOVA classification. Data were analyzed with multilevel mixed-effects regression. The results showed that sensory appeal and price were the most important motivations for food choices, while ethical concern was less important. Sensory appeal was positively associated with consumption of industrialized condiments (p = 0.022), price showed a negative correlation with consumption of plant oils (p = 0.022), ethical concern showed positive correlation within consumption white meat (p = 0.065) and negative correlation within pasta dishes (p < 0.001). Regarding the NOVA classification, health correlated with an increase in consumption of unprocessed foods (p = 0.017) and weight control with a decrease in consumption of processed culinary ingredients (p = 0.057).

Long-term effect of the Brazilian Workers' Food Program on the nutritional status of manufacturing workers: A population-based prospective cohort study.

BACKGROUND: The Brazilian Workers Food Program (WFP) is a public policy program of nutritional assistance to workers, with the main objective of improving nutritional conditions, which was implemented 40 years ago and serves over 21.4 million workers. OBJECTIVES: To compare the long-term change in anthropometric indicators of the nutritional status and dietary intake between workers of manufacturing industries adherent to and non-adherent to the WFP. METHODS: A prospective cohort study, based on a combined stratified and multistage probability sampling, was carried out, with two waves with a 4-year interval. The change in body mass index (BMI), waist circumference (WC) and dietary intake at lunch by the 24-hour recall method were compared between groups with analysis of covariance. RESULTS: A total of 273 workers in 16 industries from an initial cohort of 1069 workers in 26 industries of the State of Rio Grande do Norte in Brazil were evaluated in the two waves. The mean age was 37±10 years and 53.1% were male, with no differences between groups in age and sex distribution. BMI increased in both groups (0.44 kg/m2 in non-WFP, p = 0.003, and 0.56 kg/m2 in WFP, p = 0.0006) and WC increased in the WFP group (1.50 cm, p = 0.0006). BMI change over time did not show statistical differences between groups (p = 0.54) but WC had a greater increase in the WFP group (difference 1.37 cm, p = 0.047). There were no differences between groups in the change over time of the dietary intake. CONCLUSION: BMI and WC increased over time in manufacturing workers of industries both adherent and non-adherent to the WFP, but with a greater increase of WC in the WFP group. In order to achieve the objectives of the WFP, there will be a need for periodic evaluation and monitoring of nutritional indicators in these workers and implementation of monitoring and enforcement actions of the WFP.

Design and clinical validation of a software program for automated measurement of mammographic breast density.

BACKGROUND: Mammographic breast density is an important predictor of breast cancer, but its measurement has limitations related to subjectivity of visual evaluation or to difficult access for automatic volumetric measurement methods. Herein, we describe the design and clinical validation of Aguida, a software program for automated quantification of breast density from flat mammography images. MATERIALS AND METHODS: The software program was developed in MatLab. After image segmentation separating the background from the breast image, the operator positions a cursor defining a region of interest on the pectoralis major muscle from the mediolateral oblique view. Then, in the craniocaudal view, the threshold for separation of the dense tissue is based on the optical density of the pectoral muscle, and the proportion of dense tissue is calculated by the program. Mammograms obtained from 2 different occasions in 291 women were used for clinical evaluation. RESULTS: The intraclass correlation coefficient (ICC) between breast density measurements by the software and by a radiologist was 0.96, with a bias of only 0.67 percentage points and a 95% limit of agreement of 13.5 percentage points; the ICC was 0.94 in the interobserver reliability assessment by two radiologists with different experience; and the ICC was 0.98 in the intraobserver reliability assessment. The distribution among the density classes was close to the values obtained with the volumetric software. CONCLUSIONS: Measurement of breast density with the Aguida program from flat mammography images showed high agreement with the visual determination by radiologists, and high inter- and intra-observer reliability.

Randomized Clinical Trial of Balloon Occlusion versus Conventional Microcatheter Prostatic Artery Embolization for Benign Prostatic Hyperplasia.

PURPOSE: To compare balloon occlusion prostatic artery embolization (bPAE) with conventional microcatheter PAE (cPAE). MATERIALS AND METHODS: In this single-center trial, between November 2017 and November 2018, 89 patients with symptomatic benign prostatic hyperplasia were randomly assigned to cPAE (n = 43) or bPAE (n = 46). All patients received embolization with 300-500 µm Embosphere microspheres and were evaluated before and 1 and 6 months after PAE. Primary outcome measure was change from baseline in International Prostate Symptom Score (IPSS). Student t test was used for between-group comparisons of change from baseline, and paired t test was used for within-group comparisons. RESULTS: At baseline, groups were identical (P > .05). Unilateral PAE was performed in 4 patients receiving cPAE and 3 patients receiving bPAE (9.30% and 6.52%, P = .708). Procedural and fluoroscopy times, dose area product, air kerma, embolic volume, and mean prostate-specific antigen (PSA) 24 hours after PAE did not differ between groups (P > .05). Coils were used in 6 patients receiving cPAE and 4 patients receiving bPAE (14.0% and 8.70%, P = .51). Assessments at 6 months after PAE showed mean IPSS reduction was 7.58 ± 6.88 after cPAE and 8.30 ± 8.12 after bPAE (P = .65); mean prostate volume reduction was 21.9 cm3 ± 51.6 (18.2%) after cPAE and 6.15 cm3 ± 14.6 (7.3%) after bPAE (P = .05); mean PSA reduction was 0.9 ng/mL ± 2.22 after cPAE and 0.22 ng/mL ± 1.65 after bPAE (P = .10). Penile skin lesions (n = 3) and rectal bleeding (n = 2) were documented only in patients receiving cPAE (11.9%, P = .01). No major adverse events occurred. CONCLUSIONS: bPAE is as effective as cPAE in treating benign prostatic hyperplasia with a potential to reduce nontarget embolization.

Risk assessment of patient factors and medications for drug-related problems from a prospective longitudinal study of newborns admitted to a neonatal intensive care unit in Brazil.

OBJECTIVE: To identify patient factors and medications associated with the occurrence of drug-related problems (DRPs) in neonates admitted to neonatal intensive care units (NICUs). DESIGN: Prospective, longitudinal study. SETTING: NICU of a teaching hospital in Brazil. PARTICIPANTS: Data were collected from the records of the clinical pharmacy service of all neonates admitted between April 2014 and January 2017, excluding neonates with length of stay in the NICU <24 hours or without prescribed drugs. PRIMARY OUTCOME MEASURES: Occurrence of one or more DRP (conditions interfering in the patient's pharmacotherapy with potential undesired clinical outcomes). RESULTS: The study observed 600 neonates who had a median length of stay in the NICU of 13 days (range 2-278 days). DRPs were identified in most neonates (60.5%). In a multivariate logistic regression model, the factors independently associated with DRP were gestational age (adjusted OR (AOR) 0.85, 95% CI 0.81 to 0.89), 5 min Apgar <7 (AOR 1.74, 95% CI 1.00 to 3.13), neurological disease (AOR 2.49, 95% CI 1.09 to 5.69), renal disease (AOR 5.75, 95% CI 1.85 to 17.8) and cardiac disease (AOR 2.36, 95% CI 1.31 to 4.24). The medications with greater risk for DRP were amphotericin B (AOR 4.80), meropenem (AOR 4.09), alprostadil (AOR 3.38), vancomycin (AOR 3.34), ciprofloxacin (AOR 3.03), gentamicin (AOR 2.43), cefepime (AOR 1.88), amikacin (AOR 1.82) and omeprazole (AOR 1.66). These medicines represented one-third of all prescribed drugs. CONCLUSIONS: Gestational age, 5 min Apgar <7, and neurological, cardiac and renal diseases are risk factors for DRP in NICUs. Alprostadil, omeprazole and several anti-infectives were associated with greater risk of DRP.

Prostatic Artery Embolization for Benign Prostatic Hyperplasia: Prospective Randomized Trial of 100-300 µm versus 300-500 µm versus 100- to 300-µm + 300- to 500-µm Embospheres.

PURPOSE: This study compared the safety and efficacy of prostatic arterial embolization (PAE) with that of trisacryl gelatin microspheres of different sizes for treatment of benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: This study consisted of a single-center, randomized controlled clinical trial in 138 patients who underwent PAE for BPH between July 2015 and December 2016. Patients were randomized to PAE using microspheres of different sizes: group A patients were treated with microspheres 100-300 µm, group B with 300-500 µm, and group C with 100-300 µm followed by 300-500 µm. All patients were evaluated before and at 1, 3, 6, 12, and 18 months after PAE. Baseline data were comparable across the 3 groups, using the following mean International Prostate Symptom Score/quality of life (IPSS/QoL); prostate volume (PV) scores, respectively: 23.0/4.14; 87.9 cm3 (group A); 23.0/4.09; 89.0 cm3 (group B); and 24.2/4.29; 81.0 cm3 (group C) (P > 0.05). RESULTS: Mean IPSS/QoL scores; PV after PAE were: 9.98/2.49; 65.1 cm3 (group A); 8.24/2.26; 63.1 cm3 (group B); and 10.1/2.69; 53.1 cm3 (group C) (P = 0.23; P = 0.39; P = 0.24). There were 26 clinical failures. The cumulative probabilities of clinical success at 18 months were 76.7% in group A, 82.6% in group B, and 83.3% in group C (P = 0.68). Nontarget embolization was prevented in 6 patients by coil embolization. All adverse events were mild and self-limited with rates of 86.0% in group A (37 of 43); 41.3% in group B (19 of 46); and 58.3% in group C (28 of 48) (P < 0.001). Dysuria was the most frequent adverse event (28 of 137 [20.4%]). CONCLUSIONS: PAE outcomes were not significantly different among microspheres of different sizes. The use of 100- to 300-µm microspheres was associated with an increased risk of minor adverse events.

Safety and Efficacy of Prostatic Artery Chemoembolization for Prostate Cancer-Initial Experience.

PURPOSE: To evaluate outcome of prostatic artery chemoembolization for patients with prostate cancer (PCa). MATERIALS AND METHODS: This single-center prospective cohort study was conducted between August 2013 and July 2016 in 20 patients with PCa who underwent chemoembolization. Mean patient age was 67.5 years ± 6.4. Gleason score was 6-10, and staging was T2N0M0. Fifteen patients refused prostatectomy and 5 wanted to stop hormonal therapy because of side effects. For chemoembolization, Chelidonium majus mother tincture 1 mL was slowly injected into the prostatic arteries. Docetaxel 1 mL and 150-300 µm Embosphere (Merit Medical Systems, Inc, South Jordan, Utah) microspheres 0.5 mL were thoroughly mixed, and the mixture was slowly injected by the same route. Embolization of prostatic arteries was finished with 150-300 µm Embosphere microspheres. Technical success was defined as bilateral prostatic artery embolization. Biochemical failure was defined as prostate specific antigen (PSA) decrease to < 2 ng/mL followed by recurrence when PSA increased to > 2 ng/mL within 1 month after success. RESULTS: Technical success was 80.0% (16/20 patients). Biochemical failure was 18.7% (3/16 patients). There was 1 short-term biochemical recurrence at 4 months and 2 midterm recurrences (12-18 months). Biochemical success at 12-18 months was 62.5% (10/16 patients). Adverse events (31.3%) included a small area (2 cm2) of bladder wall ischemia, which was removed by surgery (n = 1); transient acute urinary retention (n = 1) and urinary urgency (n = 1) for 1 week; sexual dysfunction (n = 2), which completely recovered after 10 and 12 months, respectively. CONCLUSIONS: Prostatic artery chemoembolization allowed a biochemical response in patients with localized PCa and is a promising treatment.

Sedentary behavior is associated with physical activity, functional capacity, and a history of stroke in patients with heart failure. A cross-sectional study

Sedentary behavior (SB) has emerged as an important risk factor for poor health. Evidence showed that patients with heart failure (HF) exhibit high levels of SB, and that high SB increases mortality among such patients. We aimed to identify factors associated with SB in HF patients. Methods: A cross-sectional study was carried out with adults with HF and categorized under New York Heart Association (NYHA) functional class I-III. Sociodemographic, clinical, and health information were gathered. Evaluation of SB (by sitting time) and moderate-to-vigorous physical activity (MVPA) was performed by self-reported measures. Functional capacity was assessed using the Duke Activity Status Index. Simple and multivariate linear regression analyses were performed to identify the most suitable predictive model. Results: The sample (n = 80) comprised predominantly of patients in functional class I, men, and with an average age of 50.8 years. Time spent on SB totaled to 7.69 ± 2.35 h/day. Weekly volume of MVPA, functional capacity, and previous stroke were predictors of higher SB. Using simple linear regression analysis, the variables body mass index, quality of life, NYHA functional class, total comorbidities, dyslipidemia, MVPA in the leisure domain, and the use of diuretics, statins, and sildenafil were shown to have a statistically significant association with SB. Conclusion: In patients with HF, a longer time spent in SB was associated with low volumes of MVPA, low functional capacity, and history of stroke. More studies are needed to corroborate these findings.(AU)

Spontaneous Pregnancy with a Live Birth after Conventional and Partial Uterine Fibroid Embolization.

Purpose To determine pregnancy rates after conventional and partial uterine fibroid embolization (UFE). Materials and Methods The study received institutional review board approval and all patients gave written informed consent. A retrospective analysis of data collected prospectively was performed between June 2004 and June 2014 in a cohort of 359 women (mean age, 35.9 years ± 4.8) with uterine fibroids and/or adenomyosis who were unable to conceive. The median follow-up period was 69 months (range, 6-126 months). Under local anesthesia, both uterine arteries were embolized. In 160 patients, partial embolization was intentionally performed to preserve fertility, which may be decreased after conventional UFE. In partial UFE, only the small arterial vessels to the fibroids were embolized, leaving the large vessels of the fibroids patent. The Kaplan-Meier method and Cox regression were used for the statistical analysis. Results During follow-up, 149 women became pregnant, 131 women had live births, and 16 women had several pregnancies, resulting in a total of 150 live newborns. It was the first pregnancy for 85.5% (112 of 131) of women. Spontaneous pregnancy rates at 1 year and 2 years after UFE were 29.5% and 40.1%, respectively. The probability of successful pregnancy with live birth at 1 year and 2 years was 24.4% and 36.7%, respectively. Clinical success for fibroid-related symptoms was 78.6% (282 of 359). A dominant submucosal fibroid and ischemia greater than or equal to 90% had greater likelihood of spontaneous pregnancy. Complication rates in patients treated with partial UFE (14.6%) were not greater than rates in patients treated with conventional UFE (23.1%, P = .04). Conclusion Conventional and partial UFE may be safe and effective outpatient procedures for women with uterine fibroids who want to conceive. © RSNA, 2017.

Medium- and Long-Term Outcome of Prostate Artery Embolization for Patients with Benign Prostatic Hyperplasia: Results in 630 Patients.

PURPOSE: To confirm that prostatic artery embolization (PAE) has a positive medium- and long-term effect in symptomatic benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Between March 2009 and October 2014, 630 consecutive patients with BPH and moderate-to-severe lower urinary tract symptoms refractory to medical therapy for at least 6 months or who refused any medical therapy underwent PAE. Outcome parameters were evaluated at baseline; 1, 3, and 6 months; every 6 months between 1 and 3 years; and yearly thereafter up to 6.5 years. RESULTS: Mean patient age was 65.1 years ± 8.0 (range, 40-89 y). There were 12 (1.9%) technical failures. Bilateral PAE was performed in 572 (92.6%) patients and unilateral PAE was performed in 46 (7.4%) patients. The cumulative clinical success rates at medium- and long-term follow-up were 81.9% (95% confidence interval [CI], 78.3%-84.9%) and 76.3% (95% CI, 68.6%-82.4%). There was a statistically significant (P < .0001) change from baseline to last observed value in all clinical parameters: International Prostate Symptom Score (IPSS), quality-of-life (QOL), prostate volume, prostate-specific antigen, urinary maximal flow rate, postvoid residual, and International Index of Erectile Function. There were 2 major complications without sequelae. CONCLUSIONS: PAE had a positive effect on IPSS, QOL, and all objective outcomes in symptomatic BPH. The medium- (1-3 y) and long-term (> 3-6.5 y) clinical success rates were 81.9% and 76.3%, with no urinary incontinence or sexual dysfunction reported.

Predictors of Clinical Outcome after Prostate Artery Embolization with Spherical and Nonspherical Polyvinyl Alcohol Particles in Patients with Benign Prostatic Hyperplasia.

Purpose To assess predictors of outcome after prostate artery embolization (PAE) for benign prostatic hyperplasia with spherical particle polyvinyl alcohol (sPVA) and compare outcomes with the use of nonspherical particle polyvinyl alcohol (nsPVA). Materials and Methods This was a single-center retrospective institutional review board-approved study conducted from 2009 to 2015 in patients undergoing PAE with sPVA (n = 186; mean age ± standard deviation, 65.5 years ± 7.7) and nsPVA (n = 300; mean age, 65.3 years ± 7.6). The two cohorts were compared and analyzed for predictors of outcome with a Cox proportional hazards model and linear regression. Post-PAE prostate ischemia was measured with contrast material-enhanced magnetic resonance (MR) imaging in 23 patients with nsPVA and 25 patients with sPVA. The 24-hour post-PAE prostate-specific antigen (PSA) level was registered in 133 patients with sPVA. Prognostic values of MR imaging and PSA levels 24 hours after PAE were assessed with Cox and random-effects regressions. Results Predictors of clinical failure were older age (age over 65 years, P = .002), unilateral procedure (P = .002), and higher baseline International Prostate Symptom Score (IPSS, P = .033). Adjusted hazard ratio for clinical failure of sPVA was 1.273 (P = .16). Acute urinary retention was a predictor of lower IPSS after PAE (P = .002). The mean proportion of prostate ischemia was 11% with sPVA and 10% with nsPVA (P = .65). Lower IPSS after PAE was associated with a higher proportion of prostate ischemia (P = .009). Patients with a PSA level of at least 75 ng/mL (75 µg/L) 24 hours after PAE had a greater decrease in IPSS (P = .01). Prostate ischemic volume and PSA level 24 hours after PAE were correlated (Pearson r = 0.64, P = .014). Conclusion Clinical outcome was similar after PAE with sPVA and nsPVA. Younger age (up to 65 years), bilateral PAE, lower baseline IPSS, and acute urinary retention were predictors of better clinical outcome. The PSA level 24 hours after PAE correlated with prostate ischemia, and both correlated with clinical outcome. (©) RSNA, 2016.

Clinical Utility of the Mig-SCog.

BACKGROUND: Mig-SCog is a 9-item questionnaire developed to quantify attack-related cognitive complaints in migraine (M). The items relate to executive function and language, and the total Mig-SCog score is the sum of those scales. OBJECTIVE: To evaluate the Mig-SCog scores regarding cognitive symptoms during a variety of conditions. METHODS: We conducted a prospective comparative study of the Mig-SCog scores (1) between migraine and tension-type headache (TTH) patients during a headache; (2) in migraine patients between migraine attacks, non-headache pain and pain-free status; (3) in migraine patients during and outside a migraine attack. RESULTS: One hundred forty-nine patients (98 M and 51 TTHA). Total Mig-SCog score was higher in migraine patients than TTH (8.0 ± 4.1 vs 3.4 ± 3.2, P < .0001). Sixty-three patients took part in the next part of the study. Migraine patients rated the Mig-SCog higher for migraine (7.9 ± 4.6) than for non-headache pain (2.3 ± 2.9, P < .0006) or pain-free (1.6 ± 2.4, P < .0006). In the final phase of the study, 38 patients Mig-SCog scores were not significantly different whether obtained during or outside an M attack (P = .26). CONCLUSIONS: Attack-related subjective cognitive symptoms, assessed by Mig-SCog scores, differed between migraine and TTH patients. The Mig-SCog scores from migraine patients were found to be higher during migraine than during non-headache pain or pain-free conditions. Patient scoring from memory for usual attacks was not significantly different to scoring within attacks, We believe this demonstrates negligible recall bias.

Prostate Embolization as an Alternative to Open Surgery in Patients with Large Prostate and Moderate to Severe Lower Urinary Tract Symptoms.

PURPOSE: To evaluate efficacy of prostate artery embolization (PAE) in patients with benign prostatic hyperplasia (BPH), prostate volume (PV) > 100 cm(3). MATERIALS AND METHODS: This was a single-center retrospective cohort study. Between March 2009 and September 2014, PAE was performed in patients with a diagnosis of BPH, PV > 100 cm(3), and moderate to severe lower urinary tract symptoms (LUTS) refractory to medical treatment for at least 6 months or who had acute urinary retention. Success was defined as improved symptoms (International Prostate Symptom Score ≤ 15 and decrease of ≥ 25% from baseline score), improved quality of life (measured as score of ≤ 3 points or decrease of ≥ 1 point from baseline), and no need for additional treatment. RESULTS: PAE was performed in 152 patients 48-87 years old (mean ± SD 67.4 y ± 7.5) with mean PV of 134.2 cm(3) ± 41.8 (range, 101-383 cm(3)). PAE was technically successful in 149 patients (98.0%). Symptomatic control was achieved for a median of 18 months ± 15.5 (range, 3-66 mo). There were 33 clinical failures (23.6%); 23 occurred in the short-term (≤ 6 mo), and 10 occurred in the medium-term (6-24 mo); there were no long-term failures (> 36 mo). Cumulative clinical success rates were 90%, 87.9%, 83.5%, 81.1%, and 77.8% at 1, 3, 6, 12, and 18 months and 72.4% thereafter to 66 months (5.5 y). CONCLUSIONS: PAE provides sustained short-, medium-, and long-term control for LUTS in patients with BPH and PV > 100 cm(3).

Subjective Cognitive Symptoms During a Migraine Attack: A Prospective Study of a Clinic-Based Sample.

BACKGROUND: A migraine attack aggregates a range of different symptoms, besides pain, that contribute to attack-related disability. Cognitive dysfunction is an unacknowledged part of the migraine attack. OBJECTIVE: To provide a profile of the frequency and character of migraine attack-related cognitive symptoms occurring during the headache phase of the attack. STUDY DESIGN: Cross-sectional survey. SETTING: Clinical-based sample of episodic migraine patients. METHODS: Sequential patients were screened about the occurrence of cognitive symptoms during migraine attacks using an open-ended question followed by a self-fulfilled symptom checklist. RESULTS: Of 165 migraine patients (15 men, age average 37.3 ± 10.7 years), 89.7% described cognitive symptoms during the headache phase of the migraine attack. On average 2.5 ± 1.6 symptoms were reported per patient, uninfluenced by demographic or disease-related variables. The most common spontaneous symptoms related to executive functions, such as poor ability to concentrate (37%), difficulty in reasoning (25%), and thinking (23%). The pattern of responses on the symptoms checklist corroborated with those reported spontaneously and quantitative scores of the checklist were higher in patients with spontaneous symptoms. LIMITATIONS: Open-ended questions tend to overestimate frequency; data accuracy may be influenced by the population chosen (clinical-based, some using prophylactic treatment). CONCLUSIONS: This study detailed the frequency and characteristics of migraine attack-related subjective cognitive symptoms and found its frequency to be similar to reports of other migraine defining symptoms (ex. nausea, photophobia) in recent clinical series. Patients' reports were consistent and dominated by complaints of attention difficulties, diminished cognitive efficiency, and processing speed impairment.

The impact of cognitive symptoms on migraine attack-related disability.

BACKGROUND: The socio-economic impact of migraine is mostly related to work loss either by absenteeism or decreased work performance. Migraine-associated cognitive dysfunction during an attack may contribute to these difficulties. OBJECTIVE: The objective of this article is to analyze the presence and relevance of cognitive symptoms during migraine attacks and to relate their intensity and symptom-related disability with other migraine-defining symptoms. METHODS: Consecutive migraine patients of a headache clinic completed diaries scoring each migraine symptom (including cognitive symptoms) intensity and symptom-related disability. RESULTS: Of 100 consecutive patients included in this study, 34 (all females, age average 31.8 ± 8.8 years) returned information on 229 attacks, on average 6.7 per participant. Every symptom's intensity was always rated slightly higher than the disability it caused. Pain was the symptom scored with the highest intensity and disability, followed by cognitive symptoms (difficulty in thinking and worsening with mental effort) and photo- and phonophobia. Scoring was independent of any of the clinical variables. Attack intensity and disability scores correlated with intensity and disability from pain and from worsening with mental effort. CONCLUSIONS: Attack-related cognitive symptoms are intense and disabling. Some attack-related cognitive symptoms correlate to intensity and disability subjectively attributed to the migraine attack. Cognitive performance should be addressed as a valuable secondary endpoint in trials of acute migraine treatment.

Rationality of Antimicrobial Prescriptions in Community Pharmacy Users.

BACKGROUND: Although there is a conflict between the treatment benefits for a single individual and society, restrictions on antibiotic use are needed to reduce the prevalence of resistance to these drugs, which is the main result of irrational use. Brazil, cataloged as a pharmemerging market, has implemented restrictive measures for the consumption of antibiotics. The objective of this study was to investigate the quality of antimicrobial prescriptions and user knowledge of their treatment with these drugs. METHODS AND FINDINGS: A two-stage cross-sectional, combined and stratified survey of pharmacy users holding an antimicrobial prescription was conducted in the community between May and November 2014. A pharmacist analyzed each prescription for legibility and completeness, and applied a structured questionnaire to the users or their caregivers on their knowledge regarding treatment and user sociodemographic data. An estimated 29.3% of prescriptions had one or more illegible items, 91.3% had one or more missing items, and 29.0% had both illegible and missing items. Dosing schedule and patient identification were the most commonly unreadable items in prescriptions, 18.81% and 12.14%, respectively. The lack of complete patient identification occurred in 90.53% of the prescriptions. It is estimated that 40.3% of users have used antimicrobials without prescription and that 46.49% did not receive any guidance on the administration of the drug. CONCLUSIONS: Despite the measures taken by health authorities to restrict the misuse of antimicrobials, it was observed that prescribers still do not follow the criteria of current legislation, particularly relating to items needed for completion of the prescription. Moreover, users receive little information about their antimicrobial treatment.

Cognitive dysfunction during migraine attacks: a study on migraine without aura.

BACKGROUND: Cognitive difficulties contribute to patients' disability during migraine attacks and have been overlooked in migraine research. Neuropsychological studies performed during attacks have produced inconsistent findings due to design differences and limitations. OBJECTIVE: Our objective is to document changes in cognitive performance of migraine patients during migraine attacks with a comprehensive battery of cognitive/behavioral tests, while controlling for potential confounders. METHOD: A prospective two-period, randomized, cross-over study compared within-subject neuropsychological evaluation in two conditions-during a naturally occurring untreated migraine attack and a headache-free period. RESULTS: Thirty-nine patients with episodic migraine (37 females, average 38 years old) were included and 24 completed the study. Participants performed worse during the attack in the majority of cognitive tests, compared to the headache-free status, and significantly so in word reading speed (p = 0.013), verbal learning (p = 0.01), short-term verbal recall with (p = 0.01) and without (p = 0.013) semantic cueing and delayed recall with (p = 0.003) and without (p = 0.05) semantic cues. Differences found were unrelated to age, gender, literacy, condition order, interval between evaluations, anxiety, pain intensity or duration of the attack. DISCUSSION: Cognitive performance decreases during migraine attacks, especially in reading and processing speed, verbal memory and learning, supporting patients' subjective complaints. These findings suggest the existence of a reversible brain dysfunction during attacks of migraine without aura, which can relate specifically to migraine or be a consequence of acute pain processing by the brain.
