Colorectal cancer (CRC) screening with fecal occult blood tests (FOBTs) improves outcomes in men moreso than women, and especially in men with left-sided tumors, say Finnish researchers.

Scientists have modeled the first step in human development in a laboratory with the goal of better understanding how organs form. In the new study, the researchers edited groups of human pluripotent stem cells to silence genes important for cellular mechanics. The alterations prompted the cells to move around and self-organized until they were divided into two groups: Those that had been manipulated and those that had not.
Family care of an older adult has emerged as an essential element of the U.S. health care system, with 83% of long-term care provided to older adults coming from family members or other unpaid helpers. As the population of older adults grows, so too does the expectation of family care for persons living with dementia.
Triple therapy reduces chronic obstructive pulmonary disease (COPD) exacerbations and improves lung function and quality of life more than dual therapy or monotherapy in patients with advanced COPD, according to a new review and meta-analysis.
Breathlessness is a common symptom in advanced disease and can lead to panic and anxiety for patients and their family. It can trouble people even when resting or performing light activities around the home. With our aging population and increasing multi-morbidity, the number of people affected by breathlessness worldwide is set to rise.
Researchers have generated six Zika virus antibodies that could be used to test for and possibly treat a mosquito-borne disease that has infected more than 1.5 million people worldwide. The antibodies "may have the dual utility as recognized Zika virus subtypes and may be further developed to treat Zika virus infection," corresponding author Ravi Durvasula, MD, and colleagues report in a study published in the journal PLOS ONE.
Researchers have discovered how bacterium manage to destroy enemy DNA, while keeping their own genetic material safe. When foreign bodies attack, the molecular militia that comprises our immune system goes to war. In the chaos of battle, this cavalry must be careful not to fire on its own soldiers; and organisms ranging from humans to bacteria have evolved special mechanisms to avoid this type of mix-up.
Researchers have developed a systematic way to compare the immune responses of humanized mice versus humans. They used this new testing platform to show that a newly developed humanized mouse shares significant immune-system responses with humans.
Researchers have discovered that certain derivatives of amodiaquine, a medication used to treat malaria, could provide a new therapeutic approach to patients infected with Ebola virus disease by blocking the viruses from entering cells.
Using a small and inexpensive biosensor, researchers at UBC Okanagan, in collaboration with the University of Calgary, have built a diagnostic tool that provides health care practitioners almost instant diagnosis of a bacterial infection.
Researchers have found that their individual perception of genetically modified organisms might impact their judgments about whether or not nanotechnology-enabled products should be labeled in stores. If an individual is skeptical about the safety of genetically modified foods, chances are they are wary of nanotechnology, too.
