Brazilian Consensus on Photoprotection

Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of nonmelanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection

Effects of alirocumab on types of myocardial infarction: insights from the ODYSSEY OUTCOMES trial

Aims  The third Universal Definition of Myocardial Infarction (MI) Task Force classified MIs into five types: Type 1, spontaneous; Type 2, related to oxygen supply/demand imbalance; Type 3, fatal without ascertainment of cardiac biomarkers; Type 4, related to percutaneous coronary intervention; and Type 5, related to coronary artery bypass surgery. Low-density lipoprotein cholesterol (LDL-C) reduction with statins and proprotein convertase subtilisin–kexin Type 9 (PCSK9) inhibitors reduces risk of MI, but less is known about effects on types of MI. ODYSSEY OUTCOMES compared the PCSK9 inhibitor alirocumab with placebo in 18 924 patients with recent acute coronary syndrome (ACS) and elevated LDL-C (≥1.8 mmol/L) despite intensive statin therapy. In a pre-specified analysis, we assessed the effects of alirocumab on types of MI. Methods and results  Median follow-up was 2.8 years. Myocardial infarction types were prospectively adjudicated and classified. Of 1860 total MIs, 1223 (65.8%) were adjudicated as Type 1, 386 (20.8%) as Type 2, and 244 (13.1%) as Type 4. Few events were Type 3 (n = 2) or Type 5 (n = 5). Alirocumab reduced first MIs [hazard ratio (HR) 0.85, 95% confidence interval (CI) 0.77–0.95; P = 0.003], with reductions in both Type 1 (HR 0.87, 95% CI 0.77–0.99; P = 0.032) and Type 2 (0.77, 0.61–0.97; P = 0.025), but not Type 4 MI. Conclusion  After ACS, alirocumab added to intensive statin therapy favourably impacted on Type 1 and 2 MIs. The data indicate for the first time that a lipid-lowering therapy can attenuate the risk of Type 2 MI. Low-density lipoprotein cholesterol reduction below levels achievable with statins is an effective preventive strategy for both MI types.For complete list of authors see http://dx.doi.org/10.1093/eurheartj/ehz299</p

Effect of alirocumab on mortality after acute coronary syndromes. An analysis of the ODYSSEY OUTCOMES randomized clinical trial

Background: Previous trials of PCSK9 (proprotein convertase subtilisin-kexin type 9) inhibitors demonstrated reductions in major adverse cardiovascular events, but not death. We assessed the effects of alirocumab on death after index acute coronary syndrome. Methods: ODYSSEY OUTCOMES (Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab) was a double-blind, randomized comparison of alirocumab or placebo in 18 924 patients who had an ACS 1 to 12 months previously and elevated atherogenic lipoproteins despite intensive statin therapy. Alirocumab dose was blindly titrated to target achieved low-density lipoprotein cholesterol (LDL-C) between 25 and 50 mg/dL. We examined the effects of treatment on all-cause death and its components, cardiovascular and noncardiovascular death, with log-rank testing. Joint semiparametric models tested associations between nonfatal cardiovascular events and cardiovascular or noncardiovascular death. Results: Median follow-up was 2.8 years. Death occurred in 334 (3.5%) and 392 (4.1%) patients, respectively, in the alirocumab and placebo groups (hazard ratio [HR], 0.85; 95% CI, 0.73 to 0.98; P=0.03, nominal P value). This resulted from nonsignificantly fewer cardiovascular (240 [2.5%] vs 271 [2.9%]; HR, 0.88; 95% CI, 0.74 to 1.05; P=0.15) and noncardiovascular (94 [1.0%] vs 121 [1.3%]; HR, 0.77; 95% CI, 0.59 to 1.01; P=0.06) deaths with alirocumab. In a prespecified analysis of 8242 patients eligible for ≥3 years follow-up, alirocumab reduced death (HR, 0.78; 95% CI, 0.65 to 0.94; P=0.01). Patients with nonfatal cardiovascular events were at increased risk for cardiovascular and noncardiovascular deaths (P<0.0001 for the associations). Alirocumab reduced total nonfatal cardiovascular events (P<0.001) and thereby may have attenuated the number of cardiovascular and noncardiovascular deaths. A post hoc analysis found that, compared to patients with lower LDL-C, patients with baseline LDL-C ≥100 mg/dL (2.59 mmol/L) had a greater absolute risk of death and a larger mortality benefit from alirocumab (HR, 0.71; 95% CI, 0.56 to 0.90; Pinteraction=0.007). In the alirocumab group, all-cause death declined wit h achieved LDL-C at 4 months of treatment, to a level of approximately 30 mg/dL (adjusted P=0.017 for linear trend). Conclusions: Alirocumab added to intensive statin therapy has the potential to reduce death after acute coronary syndrome, particularly if treatment is maintained for ≥3 years, if baseline LDL-C is ≥100 mg/dL, or if achieved LDL-C is low.

Characterization of Sociodemographic and Clinicopathological Features in Brazilian Patients with Vulvar Squamous Cell Carcinoma

Aim: To investigate sociodemographic and clinical-epidemiological profiles of patients with vulvar carcinoma in Sao Paulo, the largest city of Brazil, to establish a more consistent profile of these features once the incidence of vulvar carcinoma has risen considerably. Data regarding the epidemiological aspects of this tumor are scarce. Methods: A retrospective study was performed using 300 medical records from patients diagnosed with squamous cell carcinoma of the vulva and surgically treated at A.C. Camargo Hospital in Sao Paulo, Brazil, from 1978 to 2009. Results: The median age of onset was 70 years, ranging from 15 to 98 years, and most women were white (88.51%). Most patients (83.54%) had little or no schooling and had the lowest survival curve. Many patients were diagnosed in the early stages of the disease (57.09% FIGO IB), 59% had complications due to surgery and 43.71% had disease recurrence, of which about 70% died. Conclusions: Our study adds 300 Brazilian cases of vulvar carcinoma to the world literature. Given the high rate of disease recurrence and mortality in Brazil, we conclude that regular gynecologic evaluation and educational policies should be reinforced in order to raise awareness for vulvar cancer.

Aspectos epidemiológicos da hanseníase na cidade de Recife, PE em 2002 Epidemiologic aspects of leprosy in the city of Recife, Pernambuco state, 2002

FUNDAMENTOS: Ainda é de grande importância a hanseníase como problema de Saúde Pública no Brasil, devido a sua alta endemicidade. OBJETIVO: Determinar as principais características dessa enfermidade na cidade de Recife no ano de 2002. MÉTODOS: Realizou-se estudo observacional retrospectivo, mediante o preenchimento de um questionário específico, analisando-se 100 prontuários de pacientes assistidos em centro de referência do Recife em 2002. Elaborou-se um banco de dados, e a análise foi feita utilizando-se o software EPI-Info-6. Obtiveram-se as freqüências simples das variáveis, e realizou-se análise bivariada, estudando-se as diferenças entre as proporções por meio do qui-quadrado. O ponto de corte foi p<0,05. RESULTADOS: Observou-se aumento da freqüência dos casos de hanseníase com a idade (7% dos casos ocorreram em crianças e adolescentes, e 11% em maiores de 65 anos) (p<0,001). A distribuição por sexo mostrou diferença significativa (masculino 57%, feminino 43%) (p<0,001). A forma tuberculóide possui a maior prevalência, com 42% dos casos (p<0,001) e maior incidência no sexo feminino, enquanto no sexo masculino prevaleceu a dimorfa (x²=18,83; p<0,001). As formas paucibacilares (tuberculóide e indeterminada) apresentaram lesão única ou variação de duas a cinco lesões em 55,4% e 37,5% dos casos, respectivamente (x²=37,04; p<0,001). CONCLUSÕES: Foi possível constatar que a cidade ainda é uma região endêmica devido à grande incidência da forma tuberculóide no meio, indicador epidemiológico sugestivo de tendência crescente da endemia na região. Só o diagnóstico e o tratamento precoce dos casos poderão quebrar a cadeia de transmissão da doença.<br>BACKGROUND: As a problem of Public Health in Brazil, leprosy is still important due mainly to its high endemicity. OBJECTIVES: Determine the main characteristics of this disease in the city of Recife, Pernambuco state (PE), in 2002. METHODS: Based on data acquired from a questionnaire completed by patients, a retrospective study was carried out to analyze 100 handbooks of patients attended to in a reference center of Recife in 2002. A data base was elaborated and EPI-INFO-6 software was used for the analysis. Simple variable frequencies were obtained and a bi-varied analysis was made by studying ratio differences by means of chi-square. The cut off point was p<0.05. RESULTS: An increase of leprosy was observed to occur with age (7.0% of cases in children and adolescents and 11.0% in adults over 65 years of age), (p<0.001). Distribution per sex showed significant differences (male 57.0%, female 43.0%), (p<0.001). The tuberculoid form had the highest prevalence in all of the age ranges studied, with 42.0% of cases (p<0.001), and its incidence was highest in females, while borderline cases predominated in males (x²=18.83; p<0.001). The paucibacillary forms (tuberculoid and indeterminate) showed only one lesion or two-to-five lesions in 55.4% and 37.5% of the cases, respectively (x²=37.04; p<0.001). CONCLUSIONS: It was possible to demonstrate that Recife is still an endemic region due to a high incidence of the tuberculoid form, i.e. the epidemiological pointer suggestive of increased endemic diseases in the region. Only with the diagnosis and early treatment of the cases can the transmission of the illness chain be broken

Not all identification tasks are born equal: testing the involvement of production processes in perceptual identification and lexical decision

The distinction between identification and production processes suggests that implicit memory should require more attention resources when there is a competition between alternative solutions during the test phase. The present two experiments assessed this hypothesis by examining the effects of divided attention (DA) at encoding on the high- and low-response-competition versions of perceptual identification (Experiment 1) and lexical decision (Experiment 2). In both experiments, words presented in the high-response-competition condition had many orthographic neighbours and at least one higher-frequency neighbour, whereas words presented in the low-response-competition condition had few orthographic neighbours and no higher-frequency neighbour. Consistent with the predictions of the identification/production distinction, Experiment 1 showed that DA reduced repetition priming in the high-, but not in the low-response-competition version of perceptual identification; in contrast, DA had comparable effects in the two versions of lexical decision (Experiments 2). These findings provide the first experimental evidence in support of the hypothesis that perceptual identification, a task nominally based on identification processes, might involve a substantive production componen
