O impacto da elevação do nível do mar em doenças tropicais negligenciadas


ResearchBlogging.org
Post de Bruno Sangiorgi
A despeito do aquecimento global ser um assunto polêmico, e para muitos ainda controverso, cabe à ciência estar a par das possíveis consequências advindas deste fenômeno. Tendo como pressuposta a sua ocorrência, será inevitável a elevação do nível dos mares decorrente do derretimento das calotas polares. Ao final do século 21, espera-se que haja uma elevação do nível do mar em até 60cm, levando tanto ao recuo da zona costeira quanto à invasão da água marinha em em rios e lagos de água doce, aumentando no interior do continente a quantidade de águas salinas e salobras, respectivamente.
Dentre os muitos problemas decorrentes deste cenário, foi recentemente estudado seu possível impacto na dinâmica dos vetores de doenças infecciosas. Especial atenção foi dada aos insetos que realizam oviposição em água, pois a redução na quantidade de águas doces, associada a profusão de águas salinas e salobras, poderá influenciar na disponibilidade dos locais para oviposição e na sobrevivência das formas imaturas (ovo, larva e pupa). Estas alterações deverão implicar em flutuações na densidade vetorial, influenciando na redução ou expansão das doenças transmitidas.
Umas das hipóteses apresentadas pelos pesquisadores prevê o aumento na densidade de insetos vetores tolerantes à salinidade, bem como novos locais de ocorrência destes vetores. Baseado no fato que muitas espécies vetoras, principalmente dos gêneros Aedes, Anopheles e Culex, apresentam mecanismos fisiológicos e estruturais que permitem a tolerância a salinidade de formas imaturas, é plausível que o acréscimo na quantidade de águas disponíveis para oviposição seja acompanhado pela expansão numérica das populações e colonização de novas áreas alagadas. Esta suposição é corroborada pela expansão populacional de vetores do gênero Anopheles, seguido por surtos de malária, na região costeira da Ásia após o tsunami de 2004, fato que reproduz o que se entende por invasão marítima.
A nível global, a elevação do nível do mar associada ao aquecimento das zonas temperadas tornará estas regiões mais permissivas a sobrevivência dos insetos vetores. Isto poderá implicar na migração de populações dos vetores para o norte e sul do planeta, afetando uma parcela significativa da população mundial, pois mais da metade dela se localiza a pelo menos 60km das regiões costeiras atuais. Deste modo, extrapolando a hipótese apresentada, o surgimento generalizado de novos focos das doenças tropicais negligenciadas ao redor do globo poderá, no futuro, torná-las menos tropicais e negligenciadas.

Do blog Pós-graduando: Dúvidas sobre o preenchimento do Currículo Lattes

O blog Pós-Graduando tem tratado com frequencia do CV Lattes. Veja o texto que publicou recentemente, com resposta de Geraldo Sorte, do CNPq. (aqui)


"Desde que assumiu suas atividades como membro da Comissão da Plataforma Lattes no CNPq, o Prof. Dr. Manoel Barral-Netto tem coletado sugestões e respondido a dúvidas por meio do seu perfil no Twitter e do seu blog. Sempre fico muito contente quando vejo as atividades do cotidiano acadêmico sendo colocadas em discussão. Afinal, sem discussão não há avanço.
O preenchimento do Currículo Lattes é o segundo tema mais discutido pelos leitores aqui no posgraduando.com e em nosso perfil no Twitter, perdendo apenas para a relação [de amor e/ou ódio] entre orientadores/orientados. Por isso, encaminhei ao professor algumas dúvidas dos nossos leitores, que foram respondidas pelo Geraldo Sorte, responsável pela Plataforma Lattes no CNPq.
PG – O campo “Formação Complementar” é freqüentemente preenchido por eventos diversos, que vão desde palestras até MBAs. Que eventos devem ser considerados como “Formação Complementar”? Quais são os critérios para distingui-lo do campo “Participação em eventos”?
GS – O item “formação complementar” é destinado ao cadastro devprogramas de formação, aperfeiçoamento e atividade de extensão que não sejam cursos acadêmicos formais (cursos de extensão, cursos de formação profissional, oficinas, cursos de línguas, etc. )"

Quais os grandes avanços nas ciências da saúde em 2010?

A publicação NIH Research Matters, no seu último número, fez uma recapitulação das matérias publicadas em 2010 e indica o que considera os grande avanços, divididos em três grande tópicos:
Descobertas clínicas;
Avanços médicos promissores;
Avanços no laboratório.

Coloco abaixo as minhas escolhas da lista deles, veja a matéria completa (aqui).

Clinical Breakthroughs

Prevention, Diagnosis and Treatment of Human Disease

Levels of 2 proteins in cerebrospinal fluid might be used to identify people with Alzheimer's disease before they show clinical symptoms. A distinct Alzheimer's signature—reduced levels of a specific beta-amyloid protein and increased levels of a phosphorylated tau protein—was found in 90% of Alzheimer's patients and 72% of people with mild cognitive impairment. The NIH-funded finding could open new opportunities for developing Alzheimer’s therapies.

Microscope image of yellow-stained tb bacteria.New Test Detects TB in Less than 2 Hours 
An automated test, developed with NIH support, rapidly and accurately detected tuberculosis and drug-resistant TB bacteria. In a study of 1,730 patients, the test identified 98% of all confirmed TB cases in less than 2 hours and up to 90% of TB cases that were missed by a more common diagnostic method. The finding could pave the way for earlier diagnosis and more targeted treatment of this sometimes-deadly disease.

Illustration of the heart and blood vessels.Gene Variants Tied to Poor Outcomes with Heart Drug 
Clopidogrel, a widely prescribed anti-clotting drug, was known to be less effective for heart patients with 2 copies of a variant gene, or up to 4% of the population. An NIH-funded study showed that patients with just 1 variant—another 26% of the population—may also be at risk. The finding advances our understanding of how to tailor medications based on genetic makeup.

Photo of a girl wearing a headscarf.Immunotherapy Boosts Pediatric Cancer Survival A new antibody-based therapy prompted an immune system attack on tumor cells and significantly improved the survival rates of children with neuroblastoma, a deadly nervous system cancer. In an NIH-funded of 226 children with neuroblastoma, the new immunotherapy plus standard therapy raised the survival rate to 66%, compared to 46% for those receiving standard therapy. The study was stopped early because of the positive results.

Photo of hands holding a medicine vial and a DNA label.Patient's Whole Genome Reveals Disease and Medication Risks
By evaluating the entire genome of a 40-year-old man, scientists pinpointed gene variants linked to cardiovascular disease and several other conditions in the man’s family, as well as diseases not known to be in his family. Some variants predicted the man’s likely responses to common medications, including certain heart medications. This NIH-funded study provides a glimpse into how whole-genome sequencing might one day be used in the clinic.

Photo of a girl blowing on a dandelion.Best Treatment Differs for Kids With Asthma
Most children who have trouble controlling their asthma with low-dose inhaled corticosteroids show improvement by increasing the dose or adding another medication, an NIH-funded study reported. However, the best option differed for each child. The clinical study of over 150 children identified characteristics, such as ethnicity, that raise the likelihood of one treatment working better than another. The finding highlights the need for a personalized approach to treating pediatric asthma.

Promising Medical Advances

Findings with Potential for Enhancing Human Health

NIH researchers developed a method to generate antibodies that attack a diverse array of influenza viruses in animals. The success moves scientists closer to a universal flu vaccine—one that protects against multiple viral strains for several years. After receiving a vaccine that targets a particular viral protein, followed by a booster shot, animals produced broadly neutralizing antibodies. Most were protected from death after exposure to the deadly 1934 flu virus.

Photo of a woman reading a nutrition label.The Health Benefits of Cutting Salt 
A computer model of heart disease in U.S. adults suggested that reducing salt intake by 3 grams per day could cut the number of new cases of coronary heart disease each year by as many as 120,000, stroke by 66,000 and heart attack by nearly 100,000. It could also prevent up to 92,000 deaths and save up to $24 billion in health care costs a year, the NIH-funded researchers estimated.

Nearly 40% of the energy consumed by 2- to 18-year-olds comes in the form of "empty" calories, according to a study by NIH scientists. Half of those empty calories come from the solid fats and added sugars in just 6 sources: soda, fruit drinks, dairy desserts, grain desserts, pizza and whole milk. Experts recommend that kids limit their intake of empty calories to 20% or less of their total calories.

Microscope image of clumps of spherical bacteria.Preventing Bacterial Infections from Medical Devices
NIH scientists identified a protein that helps bacteria break away from medical devices like catheters and spread throughout the body. By treating mice with antibodies that block the protein, the researchers prevented the bacteriumStaphylococcus epidermidis from spreading from a catheter to most other organs. The finding gives insight into how complex bacterial communities called biofilms cause disease and opens up new avenues for curbing biofilm-related infections.

Insights from the Lab

Noteworthy Advances in Basic Research
Molecular model of CXCR4 structure.
Controlling Computers with Your Mind 
A brain-computer interface let people control pictures on a computer screen by activating just a few brain cells. NIH-funded scientists monitored brain cell activity via wires that sent information from patients’ brains to a computer. In a simple computer game, participants were able to use their thoughts to control the images on the monitor nearly 70% of the time. The findings shed light on how single brain cells contribute to attention and conscious thought.

Electron micrograph of rod-shaped bacteria.Gut Bacteria May Influence Metabolic Syndrome
An NIH-funded study suggested that gut microbes, along with part of the immune system, may contribute to metabolic syndrome. Mice lacking an important immune receptor grew heavier than control mice and developed several features of metabolic syndrome. When gut microbes from these mice were transplanted into control mice, the recipient mice overate, became obese and diabetic. The next step will be to explore how gut microbes affect people's eating behavior.

Coaxing the Body's Cells to Repair Damaged Joints 
NIH-supported scientists developed a technique to regenerate damaged leg joints in rabbits. The researchers created porous scaffolds in the shape of leg bone tips and added a gel to aid cartilage development. By 3 to 4 weeks after surgery, the rabbits could move around almost as well as normal rabbits. Within 4 months, both bone and cartilage had regenerated. The accomplishment could point the way toward joint renewal in humans.

Photo of a young woman studying.Stress Hormone Causes Epigenetic Changes 
Researchers found that chronic exposure to a stress hormone altered DNA in the brains of mice, prompting changes in gene expression. NIH-supported scientists found that giving mice a stress hormone caused epigenetic modifications—changes to DNA that don’t alter sequences but influence gene expression—to a gene that has been tied to posttraumatic stress disorder and mood disorders in people. The finding provides clues into how stress might affect behavior.
