CONTEXT AND OBJECTIVE: Many researchers have suggested that aspirin prevents migraines. However, the evidence is unclear. The aim of this study was to analyze the available evidence on the effect of aspirin as a migraine prophylactic. DESIGN AND SETTING: Systematic review, conducted at the Pontifícia Universidade Católica do Paraná, Brazil, and at the University of São Paulo, Brazil. METHODS:We performed electronic searches in the databases of MEDLINE/PubMed, Embase, WEB OF SCIENCE, the World Health Organization, CENTRAL and OpenGrey, and we also searched manually for interventional studies published before April 2016 that compared the effects of aspirin with a control, in adults. Two authors independently extracted data on the publication, population recruited, intervention (aspirin dosage, follow-up and combined treatment) and main outcomes (frequency, severity and duration of migraine). We evaluated the quality of the studies using the Cochrane risk-of-bias tool. RESULTS: Our search retrieved 1,098 references, of which 8 met the selection criteria for this systematic review. The total population was 28,326 participants (18-64 years old); most (96%) were men. The dosage varied from 50 to 650 mg/day across the studies. The risk of bias was generally low or unclear. The only outcome for which most of the studies included (6/8) reported a significant reduction was frequency of migraine, which was reduced at an aspirin dosage of at least 325 mg/day. CONCLUSION: Aspirin can reduce the frequency of migraines. However, the optimal dosage is unclear. RESUMO

BackgroundPsoriasis is a chronic inflammatory skin disease that often progresses with nail alterations. It is suspected that there is a correlation between nail psoriasis and enthesitis of the distal interphalangeal joint, seeming to serve as a predictor.ObjectivesTo analyze the profile of patients with nail psoriasis and correlate the presence of nail alterations with psoriatic arthritis, quality of life, extent of psoriasis and the histopathology of the nail.MethodsAn observational cross-sectional study with 40 patients with a diagnosis of psoriasis and without systemic treatment. The patient profile was researched, including quality of life and evaluated for the presence of psoriatic arthritis. The severity of the skin psoriasis and the presence of nail lesions were evaluated. Nail fragments were collected and analyzed through clipping. It obtained 100% of positivity for psoriasis in the histopathology exam of the nail plate.ResultsOf the 40 patients, 65% were diagnosed with nail psoriasis. Suggestive findings of psoriatic arthritis in hands were present in 33%, being more frequent in those with nail alteration (p = 0.01). In 92.3% of patients diagnosed with psoriatic arthritis in the hands there was some nail injury. The most frequent injuries were pitting and onycholysis.ConclusionsPatients with nail psoriasis are usually men, with worse quality of life and higher chance of psoriatic arthritis. The correlation between the nail involvement of psoriasis and psoriatic arthritis in hands confirms the association between these two forms. The clinical diagnosis of nail psoriasis did not correlate with the histological diagnosis.

To determine the effect of bariatric surgery (BS) on the prevalence of pelvic floor dysfunctions (PFD), specifically on urinary incontinence (UI), pelvic organ prolapse (POP), and fecal incontinence (FI). Data Sources: A systematic review (PROSPERO registration no. CRD42017068452) with a literature search was performed using the PubMed, Scopus, and SciELO databases for all publications related to BS and PFD, with no language restrictions, from inception to September 2018. Methods of Study Selection: Two authors screened for study eligibility and extracted data. Only prospective cohorts assessing women with morbid obesity and the prevalence of PFD before and after BS in multiple academic and private centers were included. UI, POP, and FI were defined according to the International Urogynecological Association/International Continence Society joint consensus, and diagnosis was made based on self-report or questionnaires. Tabulation, Integration, and Results: Our search strategy retrieved 957 results. Of those, 28 studies were included for full analysis, and 20 studies (n = 3684 patients) were selected for final analysis. The main reasons for exclusion were missing data before and after BS (n = 7) and combined data of men and women who underwent BS (n = 1). Laparoscopic Roux-en-Y gastric bypass was the most common surgical technique. Pooled analysis (16 studies) showed that women had a mean body mass index reduction of 12.90 kg/m 2 after treatment (95% confidence interval [CI],-14.82 to-10.97; p < .0001). The relative risk reduction was 67% (n = 19; odds ratio [OR], 0.33; 95% CI, 0.26−0.41; p < .0001) for UI, 52% (n = 5; OR, 0.48; 95% CI, 0.22−1.07; p = .07) for POP, and 20% (n = 9; OR, 0.80; 95% CI, 0.53−1.21; p = .29) for FI. Funnel plots for UI and FI did not suggest any publication bias. With regard to the standardized questionnaires for PFD, the International Consultation on Incontinence−Short Form, Pelvic Floor Impact Questionnaire-7 and its subscale Colorectal-Anal Impact Questionnaire-7, Pelvic Floor Distress Inventory-20, and its subscale Urinary Distress Inventory-6 showed statistically significantly lower scores. Sexual function, represented by the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12, showed no statistically significant improvement after surgery. Conclusion: BS has a significant impact on reducing UI, but FI and POP, in obese women.
