Text messages could be key to helping TB patients quit smoking, according to study

Tuberculosis (TB) patients who smoke will recover far more quickly if they can quit—and help could come from their mobile phones, according to new research.

As part of the trial, patients were sent encouraging and supportive text messages to see if it would help them to quit smoking more quickly.

The results, published in the JAMA, revealed that nearly three times the number of participants who received text messages quit smoking for six months, compared to participants receiving the standard printed information.

Key enzyme controls both weight gain and cholesterol levels in animal models

Obesity is a global epidemic and a major cause of morbidity and mortality because it increases the risk for comorbidities, including heart disease and fatty liver disease (MASLD). Rates of these disorders have risen as the world increasingly adopts energy-dense diets and sedentary lifestyles.

Nitric oxide is a gas molecule with pleiotropic actions in the body. These effects of nitric oxide are carried out through its binding to proteins. Too much or too little nitric oxide binding (to key proteins) causes disease.

In a study published in Science Signaling, a research team from University Hospitals and Case Western Reserve University discovered a novel enzyme (SCoR2) that removes nitric oxide from proteins controlling fat build up. Removal of nitric oxide turned on fat synthesis, establishing that SCoR2 is needed to make fat.

Neurovascular dynamics in the spinal cord from development to pathophysiology

The spinal cord vasculature in development and pathophysiology.

In brain, retina, and spinal cord the vasculature plays an active role as regulator of homeostasis and repair, but vascular cells adopt region-specific traits.

However, vascular organization and properties of spinal cord remain understudied.

Although it is assumed that spinal cord and brain neurovascular systems are built and function in the same way, the researchers challenge this view by examining specific properties underlying spinal cord vascular development, physiology, and pathology.

They highlight unique angioarchitecture and homeostatic mechanisms, and discuss how neurovascular disruption contributes to spinal disorders and regenerative failure after injury. https://sciencemission.com/Neurovascular-dynamics-in-the-sc

Ruiz de Almodóvar et al. review the unique properties of spinal cord vasculature and its interactions with neural tissue across development, physiology, and disease, highlighting future directions to address open questions in neurovascular biology and translation.

Current Risk Scores Miss Nearly Half of First Heart Attacks

Current cardiac screening tools used to prevent myocardial infarction (MI) failed to identify nearly half of people who are at risk for MI, according to a new study. Those patients had low or borderline risk as per both standard and newer risk calculators for atherosclerotic cardiovascular disease (ASCVD). Most developed symptoms within 48 hours before the event, and many would not have been recommended statins or further testing if evaluated 2 days earlier.

Nearly half of adults with a first myocardial infarction show low or borderline risk on current risk estimators. Most develop symptoms only within 48 hours and would not qualify for statins earlier.

Expanded Lung Cancer Screening Could Avert Many More Deaths

Two modeling studies suggest that making more people eligible for lung cancer screening would prevent tens of thousands of deaths in the US each year — but at what cost?

Two new modeling studies suggest that expanding lung cancer screening — to include more smokers or even lifelong nonsmokers — would save thousands more lives in the US every year. But not everyone is convinced the projected benefits would outweigh the harms.

In one study, published in JAMA, researchers at the American Cancer Society (ACS) found that only about 19% of currently eligible Americans underwent lung cancer screening in 2024.

That, the study projected, could translate to roughly 15,000 lung cancer deaths averted over 5 years. But 100% screening uptake would save three times as many lives.
