Pulse oximeters miss hypoxemia more often in people with darker skin, study finds

This large prospective UK study compared five low-cost fingertip pulse oximeters with arterial blood gas measurements and found that readings varied systematically by skin tone and oxygen saturation level. Small average overestimations in darker skin translated into clinically meaningful increases in missed hypoxemia at commonly used SpO2 thresholds.

Father's early behavior linked to child's heart and metabolic health years later

How a new father behaves toward his baby can change family dynamics in a way that affects the child's heart and metabolic health years later, according to a new study by researchers in the Penn State College of Health and Human Development.

New noninvasive technique can quickly collect 3D images of the human body

In a proof-of-concept study funded by the National Institutes of Health, researchers from the Keck School of Medicine of USC and the California Institute of Technology (Caltech) have shown that an innovative, noninvasive technique can be used to quickly collect 3D images of the human body, from head to foot.

Repurposed Alzheimer’s medication offers low-cost hope for sickle cell anemia

Sickle cell anemia is the world's most common genetic disorder. It causes the red blood pigment hemoglobin to crystallize, which results in rigid, malformed red blood cells with a sickle shape.

IV iron dextran more cost-effective than oral iron for women with heavy menstrual bleeding and IDA

A single dose of intravenous (IV) iron dextran is the cost-effective treatment for women with heavy menstrual bleeding and iron deficiency anemia (IDA), according to new research published in Blood Advances.

Common blood signals explain why chronic diseases cluster as we age

This population-based study shows that shared and pattern-specific blood biomarkers reflect biological vulnerability underlying multimorbidity and the pace at which chronic diseases accumulate in older adults. Metabolic and systemic stress markers such as GDF15, HbA1c, cystatin C, and insulin consistently tracked higher disease burden and faster accumulation, with findings replicated across cohorts.

Simple fruit granola intervention shows promising cardio-renal signals in CKD patients

A single-arm intervention study in Japanese adults with moderate chronic kidney disease found that replacing breakfast with fruit granola for two months lowered systolic blood pressure, reduced LDL-related lipid markers, and decreased a urinary marker of tubular injury. Renal function remained stable, bowel habits improved, and findings were exploratory due to the small, open-label design.

Heavy menstrual bleeding linked to iron deficiency in teenage girls

More than half of teenage girls experienced heavy bleeding and 40 per cent had an iron deficiency. The research, led from Lund University in Sweden, also shows that young teenage girls who experience heavy menstrual bleeding – and are therefore at greater risk of iron deficiency – can be identified using a simple questionnaire.

Intermittent fasting edges daily calorie cuts for blood pressure and long-term cardiovascular risk estimates

In a real-world registry study of adults with overweight or obesity, 5:2 intermittent fasting and daily calorie restriction both improved blood pressure over 12 weeks. Intermittent fasting produced modestly greater reductions in systolic and pulse pressure and a larger drop in BMI-based 30-year cardiovascular risk scores, without superior lipid or glycaemic effects.

Why the form of vitamin B12 you take may matter more than your intake

This comprehensive review examines vitamin B12 absorption, physiological roles, deficiency states, and dietary sources, with particular attention to differences between natural and synthetic forms. The authors conclude that while all B12 forms raise circulating levels, methylcobalamin may offer advantages in specific clinical contexts, especially where absorption or metabolic conversion is impaired.

Filtered coffee shows a causal link to healthier HbA1c levels

Genetically predicted filtered coffee consumption is causally associated with lower HbA1c levels, while other coffee preparation methods show no such benefit. This effect appears to be partly mediated by increases in propionate producing gut bacteria, particularly Veillonella.

Early warning for diabetes: AI model identifies prediabetes risk with high accuracy

A Scientific Reports study developed a pattern neural network that integrates total antioxidant status with clinical and metabolic markers to predict prediabetes in Indian adults. The model achieved very high accuracy and highlighted oxidative stress and waist circumference as key predictors, supporting earlier detection before progression to type 2 diabetes.

Home-delivered, medically tailored groceries benefit people with diabetes facing food insecurity

A new study in the Journal of Nutrition Education and Behavior (JNEB), published by Elsevier, evaluated a 12-week home-delivered food and education program among adults in Northwest Arkansas.

Poor dietary iron weakens lung memory T cells after flu infection

Dietary iron deficiency in mice alters lung T cell activation during influenza infection and leads to memory T cells that are present in normal or increased numbers but have impaired antiviral cytokine responses. These functional deficits are most pronounced in lung CD8-positive memory T cells and persist even under optimal recall conditions.

Quality improvement project dramatically boosts iron deficiency screening in pregnancy

Within a year of initiation, a multidisciplinary project to improve screening and treatment for iron deficiency in pregnancy resulted in a sixfold rise in screening rates for iron deficiency in pregnant patients, a 20-fold rise in the number of intravenous (IV) iron infusions, and a significant improvement in median hemoglobin levels.

Intravenous iron shows safe and beneficial outcomes for patients with bacterial infection and anemia

Treatment with intravenous (IV) iron significantly improved survival and increased hemoglobin levels in patients with iron-deficiency anemia who were hospitalized for an acute bacterial infection, according to an analysis of data from more than 85,000 patients.

Challenges and opportunities in delivering gene therapies for sickle cell disease and beta thalassemia

The first study assessing the real-world commercial roll-out of gene therapies for sickle cell disease and beta thalassemia offers lessons learned to inform best practices as manufacturers and medical centers prepare to meet growing demand for gene therapies in the coming years.

New evidence shows hematopoietic cell transplantation offers durable relief for sickle cell disease

Patients who underwent hematopoietic cell transplantation for sickle cell disease saw high rates of survival without disease symptoms and low rates of severe side effects or complications years after their procedure, according to a new study.

Exa-cel shows complete success in early pediatric trials for sickle cell disease and beta-thalassemia

Preliminary results from two trials of the gene therapy exagamglogene autotemcel (exa-cel) suggest the therapy offers an effective cure for beta-thalassemia and sickle cell disease in children younger than 12.

Higher PFAS levels reduce blood sugar improvements after teen bariatric surgery

A new USC study shows teens with higher blood levels of per- and polyfluoroalkyl substances (PFAS) measured before bariatric surgery had smaller improvements in blood sugar over five years, including fasting glucose and hemoglobin A1c (HbA1c), which measures average blood sugar levels over the past 60-90 days.
