Johns Hopkins scientists develop personalized blood tests for cancer using whole genome sequencing

Researchers at Johns Hopkins have developed a new approach to detect cancer using whole genome sequencing, identifying rearrangements of DNA that can be found in tumor cells. This approach, called Personalized Analysis of Rearranged Ends (PARE), may help clinicians tailor treatments and monitor tumor levels after therapy.

All eyes on retinal degeneration

Scientists studying fruit flies have discovered a critical step in fly vision that is also linked to human retinal dystrophies, which cause visual impairments or blindness. The study's findings suggest that using flies as a model organism can lead to the development of new therapies for treating human retinal degeneration.

Making a better medical safety checklist

A Johns Hopkins researcher warns that medical safety checklists are no magic wand and require a culture change to be effective. Checklists can work in certain situations, such as central-line infection prevention, but over-reliance on them can lead to distractions and errors.

Seniors stymied in wait for kidney transplants

A third of seniors over 65 wait too long for lifesaving kidney transplants because their doctors don't list them for organs suitable for younger patients but not for themselves. Older adults have shorter life spans than younger recipients, but accepting older kidneys can increase survival rates.

Sweet! -- sugar plays key role in cell division

Researchers at Johns Hopkins Medicine discovered that sugar-based protein modification called O-GlcNAcylation regulates cell division. Disrupting this process can lead to polyploidy, a condition exhibited by many cancer cells. The findings have implications for new treatments for diseases like cancer.

Argonautes: A big turn-off for proteins

Johns Hopkins researchers have discovered how Argonaute protein binds to microRNAs, shutting down protein production. This finding sheds light on the regulation of genes and has implications for treating diseases linked to genetic regulation, such as cancer.

Children of Spanish-speaking moms watch less TV

Research by Johns Hopkins Medicine found that children of Hispanic mothers who speak Spanish spend nearly two-and-a-half hours watching TV, compared to about 90 minutes for children with English-speaking mothers. The study suggests cultural perceptions and lack of programming in Spanish may contribute to the difference.

Lighter sedation for elderly during surgery may reduce risk of confusion, disorientation after

A new study by Johns Hopkins researchers suggests that limiting the depth of sedation during procedures could safely cut the risk of postoperative delirium by 50 percent. Lighter sedation was associated with a one-day reduction in the duration of delirium in those patients who still emerged from surgery confused and disoriented.

Reasoning through the rationing of end-of-life care

A Johns Hopkins neurologist argues that futile and expensive end-of-life care can be a major contributor to the unaffordable cost of healthcare. He suggests weighing patient autonomy against societal costs and suggests 'nudging' families towards comfort care, particularly in cases of premature births.

Small amounts of lead may damage children's kidneys

A Johns Hopkins Children's Center study found that even small amounts of lead in healthy children's bodies can impair kidney function, with those having higher levels showing decreased kidney filtration rates. The researchers measured kidney function using two tests and found a link between higher lead levels and worse kidney function ...

'Mini' transplant may reverse severe sickle cell disease

A phase I/II study at Johns Hopkins Medicine has shown that mini stem cell transplantation can safely reverse severe sickle cell disease in nine out of ten patients. The procedure, which uses intravenous transplants of blood-forming stem cells from healthy donors, promotes the coexistence of host and donor cells.

Potential new 'twist' in breast cancer detection

Researchers at Johns Hopkins Medicine have discovered a protein called Twist that accurately distinguishes stem cells driving aggressive breast cancer from other cancer cells. The protein's presence alone can flag a tumor cell as a breast cancer stem cell, suggesting new potential for early detection and treatment strategies.

Stem cells battle for space

Researchers found that stem cells from flies lacking SOCS protein had more integrin, allowing them to stick to the niche better than neighboring germline stem cells. This model can be applied to other stem cell niches such as cancer, where cancer stem cells become a danger when they become sticky.
