A case of envenomation by neotropical Opisthoglyphous snake Thamnodynastes pallidus (Linnaeus, 1758) (Colubridae: Dipsadinae: Tachymenini) in Brazil

This is a case report of a bite by an Opisthoglyphous snake Thamnodynastes pallidus (Linnaeus, 1758) in an undergraduate herpetologist observed at the Universidade Federal da Paraiba (Rio Tinto, PB, Brazil). The female victim was bitten in her left hand between the index finger and the middle finger and presented symptoms of local envenomation such as bleeding, itching, pain in the wound and swelling. The patient was first seen at the University and afterwards at home during the 36 hours following the incident, when the symptoms disappeared. This is the first case report of an accident by T. pallidus in a human being in Brazil

Production of Acalypha wilkesiana seedlings using stem cuttings

The objective of this work was to evaluate the rooting of cuttings of Acalifa (Acalypha Wilkesiana) with different concentrations of indolbutyric acid (IBA). The matrix plant from which the cuttings were taken, is planted as a hedge and located at the biology institute of the Federal Rural University of Rio de Janeiro in the city of Seropédica-RJ. The experimental design was completely randomized, in a 3x3 factorial, with three different concentrations of IBA (0, 1000 and 2000 mg L-1 or 0, 2000 and 4000 mg L-1 for 15 seconds) and three types of cuttings (herbaceous, semi-woody and woody), with three replications and ten cuttings per plot. The experiments were carried out at two different times, namely: autumn and winter / spring. The following were evaluated: percentage of live cuttings, rooted, with callus and sprouting, number of roots per cut, length of the largest root. Acalypha wilkesiana can be propagated by stem cuttings, whether woody, semi-woody or herbaceous cuttings. However, herbaceous cuttings have a lower percentage of survival and rooting. Also, is a species of easy rooting through cutting of stems, dispensing with the use of AIB. Stems collected in the autumn period yield greater efficiency and productivity in the propagation of cuttings by cuttings.The objective of this work was to evaluate the rooting of cuttings of Acalifa (Acalypha Wilkesiana) with different concentrations of indolbutyric acid (IBA).

Infecções cutâneas associadas à soropositividade ao HIV: uma abordagem completa

A infecção pelo vírus da imunodeficiência humana (human immunodeficiency vírus – HIV) é responsável pela síndrome da imunodeficiência adquirida, que cursa com a deterioração progressiva do sistema imune devido o acometimento de células linfocitárias, macrófagos e células dendríticas. Ademais, essa patologia se configura como um problema de saúde pública tendo em vista o potencial de complicação associado quando não tratada. Diante da grande quantidade de manifestações dermatológicas associadas à soropositividade do HIV, o presente trabalho tem como objetivo elucidar a etiologia, quadro clínico, diagnóstico, tratamento e complicação das infecções cutâneas, ou seja, decorrentes de algum agente etiológico, relacionadas ao HIV. Foi realizada uma busca nas bases de dados: Biblioteca Virtual de Saúde (BVS), Scientific Eletronic Online (Scielo) e PubMed, por meio dos descritores: “HIV” “Manifestações dermatológicas” “Infecções cutâneas”, e 10 artigos foram utilizados para o desenvolvimento do estudo. Os resultados evidenciaram que as infecções cutâneas se dividem de acordo com o grupo etiológico (viral, bacteriano, fúngico, parasitário e ectoparasitário) e sua gravidade varia a partir do acometimento do sistema imune do paciente. Ademais, foi visto que o tratamento é individualizado para cada agente etiológico, mas, o tratamento da imunossupressão decorrente do HIV sempre deve estar associado. Por fim, é necessário estar atento às interações medicamentosas envolvendo antifúngicos, anti-histamínicos e antirretrovirais e às possíveis complicações decorrentes das infecções não tratadas

Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019: a pooled analysis of 1201 population-representative studies with 104 million participants

Background Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. Methods We used data from 1990 to 2019 on people aged 30–79 years from population-representative studies with measurement of blood pressure and data on blood pressure treatment. We defined hypertension as having systolic blood pressure 140 mm Hg or greater, diastolic blood pressure 90 mm Hg or greater, or taking medication for hypertension. We applied a Bayesian hierarchical model to estimate the prevalence of hypertension and the proportion of people with hypertension who had a previous diagnosis (detection), who were taking medication for hypertension (treatment), and whose hypertension was controlled to below 140/90 mm Hg (control). The model allowed for trends over time to be non-linear and to vary by age. Findings The number of people aged 30–79 years with hypertension doubled from 1990 to 2019, from 331 (95% credible interval 306–359) million women and 317 (292–344) million men in 1990 to 626 (584–668) million women and 652 (604–698) million men in 2019, despite stable global age-standardised prevalence. In 2019, age-standardised hypertension prevalence was lowest in Canada and Peru for both men and women; in Taiwan, South Korea, Japan, and some countries in western Europe including Switzerland, Spain, and the UK for women; and in several low-income and middle-income countries such as Eritrea, Bangladesh, Ethiopia, and Solomon Islands for men. Hypertension prevalence surpassed 50% for women in two countries and men in nine countries, in central and eastern Europe, central Asia, Oceania, and Latin America. Globally, 59% (55–62) of women and 49% (46–52) of men with hypertension reported a previous diagnosis of hypertension in 2019, and 47% (43–51) of women and 38% (35–41) of men were treated. Control rates among people with hypertension in 2019 were 23% (20–27) for women and 18% (16–21) for men. In 2019, treatment and control rates were highest in South Korea, Canada, and Iceland (treatment >70%; control >50%), followed by the USA, Costa Rica, Germany, Portugal, and Taiwan. Treatment rates were less than 25% for women and less than 20% for men in Nepal, Indonesia, and some countries in sub-Saharan Africa and Oceania. Control rates were below 10% for women and men in these countries and for men in some countries in north Africa, central and south Asia, and eastern Europe. Treatment and control rates have improved in most countries since 1990, but we found little change in most countries in sub-Saharan Africa and Oceania. Improvements were largest in high-income countries, central Europe, and some upper-middle-income and recently high-income countries including Costa Rica, Taiwan, Kazakhstan, South Africa, Brazil, Chile, Turkey, and Iran. Interpretation Improvements in the detection, treatment, and control of hypertension have varied substantially across countries, with some middle-income countries now outperforming most high-income nations. The dual approach of reducing hypertension prevalence through primary prevention and enhancing its treatment and control is achievable not only in high-income countries but also in low-income and middle-income settings

Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)

From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions

Hypothalamic transcriptional expression of the kis-speptin system and sex steroid receptors differs among polycystic ovary syndrome rat models with different endocrine phenotypes

OBJECTIVES: Polycystic ovary syndrome is a heterogeneous endocrine disorder that affects reproductive-age women. The mechanisms underlying the endocrine heterogeneity and neuroendocrinology of polycystic ovary syndrome are still unclear. In this study, we investigated the expression of the kisspeptin system and gonadotropin-releasing hormone pulse regulators in the hypothalamus as well as factors related to luteinizing hormone secretion in the pituitary of polycystic ovary syndrome rat models induced by testosterone or estradiol. METHODS: A single injection of testosterone propionate (1.25 mg) (n= 10) or estradiol benzoate (0.5 mg) (n= 10) was administered to female rats at 2 days of age to induce experimental polycystic ovary syndrome. Controls were injected with a vehicle (n= 10). Animals were euthanized at 90-94 days of age, and the hypothalamus and pituitary gland were used for gene expression analysis. RESULTS: Rats exposed to testosterone exhibited increased transcriptional expression of the androgen receptor and estrogen receptor-b and reduced expression of kisspeptin in the hypothalamus. However, rats exposed to estradiol did not show any significant changes in hormone levels relative to controls but exhibited hypothalamic downregulation of kisspeptin, tachykinin 3 and estrogen receptor-a genes and upregulation of the gene that encodes the kisspeptin receptor. CONCLUSIONS: Testosterone-and estradiol-exposed rats with different endocrine phenotypes showed differential transcriptional expression of members of the kisspeptin system and sex steroid receptors in the hypothalamus. These differences might account for the different endocrine phenotypes found in testosteroneand estradiol-induced polycystic ovary syndrome rats.Fundacao de Amparo Pesquisa do Estado de Sao Paulo (FAPESP) -Brazil 2010/17417-3 2013/12830-8 Master's degree scholarship Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq) -Brazil 134694/2010-
