Global urban environmental change drives adaptation in white clover.

Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural clines was best explained by adaptive evolution, but the degree of parallel adaptation varied among cities. Our results demonstrate that urbanization leads to adaptation at a global scale

Prevalence and Severity of Periodontitis in Indonesian Patients With Rheumatoid Arthritis

<p>Background: Patients with rheumatoid arthritis (RA) may have more prevalent and severe periodontitis than healthy controls. Periodontitis may increase the systemic inflammation in RA. The aim of this study is to assess periodontitis prevalence and severity and its potential association with systemic inflammation in Indonesian patients with RA.</p><p>Methods: A full-mouth periodontal examination including probing depth, gingival recession, plaque index, and bleeding on probing was performed in 75 Indonesians with RA and 75 age-, sex-, and smoking-matched Indonesian controls. A validated questionnaire was used to assess smoking, body mass index, education, and medical conditions. In addition, in all participants, the use of drugs was noted, and erythrocyte sedimentation rates and serum levels of high-sensitivity C-reactive protein (hsCRP), rheumatoid factor, and anti-citrullinated protein antibodies were measured. Differences in periodontitis prevalence and 12 measures of periodontitis severity between patients with RA and controls were analyzed using univariate analyses.</p><p>Results: No significant differences in periodontitis prevalence and 11 measures of periodontitis severity between patients with RA and controls were observed. Conversely, patients with RA had a significantly lower surface area of healthy pocket epithelium versus controls (P = 0.008), and a tendency toward higher hsCRP levels was observed in patients with RA with severe periodontitis compared with patients with RA with no mild or moderate periodontitis (P = 0.063). It has to be noted that all patients with RA were on anti-inflammatory drugs, whereas none of the controls used such drugs.</p><p>Conclusion: Prevalence and severity of periodontitis in Indonesian patients with RA is comparable to controls but with less healthy pocket epithelium than in controls and a tendency toward a higher inflammatory state in patients with RA and severe periodontitis.</p>

Itinerário percorrido pelas mulheres na descoberta do câncer Camino recorrido por las mujeres en la descubierta del cáncer The journey experienced by women through a cancer diagnosis

Este estudo se propõe a desvelar o itinerário vivenciado pelas mulheres no processo de descoberta do diagnóstico de câncer. Como estratégia teórico-metodológica, foram utilizados o Interacionismo Simbólico e a Grounded Theory. Foram informantes do estudo 20 indivíduos 10 mulheres portadoras de câncer e seus respectivos familiares significantes. Os resultados mostram desde o momento em que elas vivenciam as primeiras percepções sobre a alteração fisiológica em seu corpo, passando pela busca de ajuda profissional, até o recebimento do diagnóstico de câncer. O itinerário apresentado permite conhecer aspectos da realidade experienciada anteriormente ao recebimento do diagnóstico e ressalta a importância de os profissionais valorizarem mais as queixas das pessoas que os procuram, percebendo que se esta procura aconteceu é porque a pessoa está preocupada. Esta atitude pode favorecer a identificação precoce do problema e, por conseguinte, garantir melhor prognóstico e qualidade de vida.<br>Este estudio propone revelar el camino vivido por las mujeres en el proceso de descubierta del diagnóstico de cáncer.

Symbolic Interactionism and Grounded Theory were used as theoretical-methodological strategies. Twenty individuals took part in the study - 10 female cancer bearers and their respective significant others. The results are described starting from the moment they experience their first perceptions of the physiologic changes in their bodies, through the search for professional help, to the acknowledgement of a cancer diagnosis. The given itinerary presents aspects of the patients' reality prior to the diagnosis, and emphasizes the importance of professionals giving more credence to the complaints of patients who seek them if the patient made an appointment, it is because that person is concerned. This attitude can promote the early identification of the problem, and consequently guarantee a better prognosis and quality of life
