Researchers aim to find the best treatment sequence to extend patient survival.
A clinical study found that young, single black women in South Africa and men who have sex with men (MSM) and transgender women (TGW) in the US and Thailand adhered to a daily pill regimen for HIV prevention. The study suggests that daily PrEP dosing is an effective strategy for this population.
A decade-long NIH-funded trial found that antiretroviral therapy consistently suppresses HIV, greatly reducing sexual transmission to uninfected partners. The study demonstrates the enduring power of HIV-controlling treatment in protecting heterosexuals from transmission.
HPTN 067 study finds that high-risk populations in Bangkok, Harlem, and South Africa can adhere to daily PrEP regimens with high levels of coverage and satisfaction. The study suggests that non-daily dosing regimens could be a cost-effective alternative for increasing accessibility to PrEP.
A clinical trial found that patients with activated B-cell-like (ABC) subtype of DLBCL responded better to ibrutinib than those with germinal center B-cell-like (GCB) subtype. This study suggests the use of ABC gene signature to identify patients likely to respond to the drug.
The HPTN 052 study demonstrates that early antiretroviral therapy significantly reduces HIV transmission in serodiscordant couples, with a sustained 93% reduction when the HIV-infected partner is on treatment and viral load suppressed. The trial also found that timely ART initiation can lead to improved health outcomes.
Researchers at UT Southwestern Medical Center have shown that a new drug, DSM265, kills malaria parasites in the blood and liver by targeting their ability to replicate. This could lead to a single-dose cure for malaria, with potential applications as both a treatment and preventive measure.
The trial showed that early FDG-PET-positive patients benefit from intensification of chemotherapy, leading to improved progression-free survival rates. However, omitting involved-node radiotherapy in early PET-negative patients did not demonstrate non-inferiority to the standard treatment in terms of progression-free survival.
Peripartum cardiomyopathy (PPCM) is a rare disorder characterized by weakened heart pumping, affecting otherwise healthy pregnant women. A new study highlights the need for further investigation into prevention and treatment options, as current evidence is scarce and of poor quality.

However, results were more equivocal for patients with traumatic injury, leaving room for further investigation.
A new study found that certain immune responses may play a role in blocking systemic HIV infection after exposure. T-cell responses against specific HIV-1 antigens were significantly higher and more frequent among those who remained uninfected compared to those who became infected, associated with reduced risk of infection.
Researchers found that serotonin receptor antagonists, commonly used to prevent nausea and vomiting after surgery, may also increase the risk of irregular heartbeats. The safest options were ondansetron plus dexamethasone for adults and dolasetron for all ages, with inconclusive findings for children.

The addition of pharmacists led to substantial improvements in patient health, including a significant impact on blood pressure control.
A study by the University of Sydney found that an ABC TV program questioning the link between cholesterol and heart disease resulted in 14,000 fewer people taking statins per week. The program's impact was seen in those at high risk of cardiovascular disease, potentially leading to preventable heart attacks and strokes.
A new trial design, called a two-by-two trial, can account for behavior-treatment interactions and provide more accurate efficacy results. By randomizing both treatment and probability of treatment, researchers can quantify the effects of treatment, behavior, and their interaction.
A study by the University of Arizona's BIO5 Institute has identified potential protective compounds in dust samples from Amish farming communities. The findings suggest that these natural environmental products could be transformed into medicines to promote lung health and prevent asthma. The research aims to understand the biological ...

A new study published in Anesthesiology found that resuming angiotensin receptor blockers within two days after surgery decreases death rates in the first month following surgery. Resuming these medications also reduced rates of infection, pneumonia, heart failure and kidney failure.
A review of 10 studies found no human data to support claims that eating placenta reduces postpartum depression or pain. Unknown risks to women and babies are also a concern due to lack of regulation and inconsistent dosing.
A new study found that keeping blood sugar levels under good control for many years can reduce the risk of heart attack, stroke, or amputation. The researchers conclude that a long-term average A1C level of around 8 is enough to achieve most cardiovascular benefits.
A RAND Corporation study found that implementing CDS tools led to a small reduction in inappropriate advanced imaging studies, increasing the proportion of tests rated as appropriate. However, challenges persist due to limited criteria availability and tool limitations.
