About The Study: In this study, gestational hypertension, preeclampsia, and eclampsia were associated with an increased risk of new-onset migraine, headache, epilepsy, sleep disorder, or mental fatigue within months to years after giving birth. Guidelines recommend follow-up after delivery for women with gestational hypertension and preeclampsia for their increased risk of cardiovascular disease. At these visits, caregivers should also pay attention to persisting or new-onset of neurological symptoms, since this group of women ...

Hospitals that have adopted the Center for Medicare and Medicaid (CMS) “hospital-at-home” program, which serves as an alternative to admission to brick-and-mortar facilities, are concentrated in large, urban, not-for-profit, and academic hospitals, new research suggests. The findings are among the first to portray the landscape of hospitals participating in this rapidly growing care model, said Dr. Hashem Zikry, a participant in the National Clinician Scholars Program at UCLA and lead author on the paper, which will be published in the peer-reviewed JAMA. “If CMS’ goal is to continue to expand hospital-at-home, these findings suggest ...

When making decisions about nutrition and diet, the focus is often on the potential impacts to the heart or brain; and gut health can frequently end up an afterthought despite a whole industry revolving around probiotics and digestive aids. With its direct link to those two important organs, should gut health be prioritized more? Imagine an entire civilization of trillions of microorganisms living in harmony inside of your digestive system. This microbiome is unique to each individual and varies greatly based on many genetic and environmental factors. The complexity of gut health can often make diagnosis of maladies difficult, especially when new ...

Quantum sensing is a rapidly developing field that utilizes the quantum states of particles, such as superposition, entanglement, and spin states, to detect changes in physical, chemical, or biological systems. A promising type of quantum nanosensor is nanodiamonds (NDs) equipped with nitrogen-vacancy (NV) centers. These centers are created by replacing a carbon atom with nitrogen near a lattice vacancy in a diamond structure. When excited by light, the NV centers emit photons that maintain stable spin information ...

Key Takeaways An expert workgroup representing primary and specialty care has developed new guidelines for comprehensive evaluation of patients who may have cognitive impairment or dementia due to Alzheimer’s disease or a related disease. Current guidelines for a comprehensive evaluation process are more than 20 years old. Results of the evaluation should be a three-step diagnostic formulation, summarizing the patient’s overall level of impairment, a brief summary of the symptoms they are experiencing, and the likely underlying brain disease(s) and/or conditions contributing to their ...
