Review examines passion fruit and blood pressure in animal and human studies

A systematic review examined whether Passiflora edulis, commonly known as passion fruit, is linked with lower blood pressure. It included six preclinical studies and two human trials; the animal and laboratory findings were generally more extensive than the human evidence. The authors reported possible blood-pressure reductions but emphasized that the human studies were small, varied in the extracts used, and short in duration.

Trial reports 40% complete response with added drugs in high-risk rectal cancer

Researchers studied 96 people with high-risk, locally advanced rectal cancer in a single-center phase II clinical trial. The treatment combined chemotherapy, short-course radiation, and a targeted drug selected for each study cohort. Overall, 40% had a complete response, but the study did not establish how this approach compares with other treatments.

Researchers report stone cultures were linked with more sepsis after urinary stone procedures

A prospective observational study of 143 people undergoing procedures for urinary stones compared pre-surgery urine cultures with cultures taken from the stones during surgery. Stone cultures were positive more often and were associated with postoperative sepsis, while pre-surgery urine culture results were not significantly associated with sepsis. Because this was an observational study, the findings show associations rather than cause and effect.

Study links robot-assisted cancer surgery with fewer short-term complications

Researchers examined short-term outcomes after 36,208 cancer operations performed at one institution from 2016 through 2025. Robot-assisted and other minimally invasive operations were associated with fewer major complications, transfusions and shorter hospital stays than open surgery in several procedure-specific comparisons, but this observational study cannot show that the surgical approach caused those differences.

Review finds higher short-term risks for some people with cirrhosis after keyhole liver surgery

This human-health systematic review and meta-analysis examined outcomes after minimally invasive liver surgery in 12,892 patients, including 5,658 with cirrhosis. Cirrhosis was associated with higher rates of blood transfusion during surgery, conversion to open surgery, complications within 90 days, and death within 90 days, although the researchers said serious risk of bias limits confidence in these findings.

Review finds reinforced staplers linked to fewer pancreatic leaks after surgery

Researchers combined results from 20 randomized trials involving 2,868 patients who had distal pancreatectomy, an operation that removes part of the pancreas. Reinforced staplers were associated with fewer clinically important pancreatic fistulas than suture-based closure, while patch techniques were associated with fewer abdominal fluid collections.

Study links genetic diabetes risk and alcohol intake with Dupuytren’s disease

Researchers analyzed human genetic data from large European-ancestry studies to examine whether diabetes, alcohol intake, obesity-related traits, or smoking might affect the risk of Dupuytren’s disease. Genetic liability for diabetes and higher genetically predicted alcohol intake were associated with a slightly higher risk, while obesity traits and smoking intensity showed no convincing association.

Review links medication-raised blood pressure to better recovery in some stroke patients

A systematic review and meta-analysis examined medication-induced increases in blood pressure during the first 72 hours after certain acute ischemic strokes. Across three studies involving 366 people, those given this treatment were more likely to be functionally independent after 90 days, although the result does not establish that the treatment caused better recovery.

New analysis links combined heart procedures to more rhythm recurrences

This human-focused meta-analysis compared catheter ablation alone with catheter ablation combined with left atrial appendage closure in 3,274 people with atrial fibrillation across 14 studies. The combined approach was associated with more recurrent abnormal heart rhythms and a slightly longer procedure time, while one serious fluid-related complication did not differ significantly between groups. Because the underlying studies were not described in full and randomized trials are still needed, the results are not conclusive.

Study links loneliness and multiple physical conditions in both directions

In a study of adults aged 45 and older from 19 countries, researchers found that multiple physical health conditions and loneliness were associated with one another over time in both directions. Social inactivity appeared to statistically mediate part of the association from physical multimorbidity to later loneliness. The observational design cannot establish cause and effect.

Trial reports weight loss with a daily oral GLP-1 medicine over 16 weeks

In a randomized, placebo-controlled phase II trial of 250 adults with overweight or obesity in China, the oral GLP-1 receptor agonist VCT220 was associated with greater average weight loss over 16 weeks than placebo. The study also reported changes in HbA1c, fasting insulin, and blood pressure, while gastrointestinal side effects were common but usually mild to moderate. Longer-term effects and safety remain uncertain.

Review finds eyelid tumors that spread often resembled harmless growths

This human systematic review combined 73 published case reports and case series involving 95 people with biopsy-confirmed cancer spread to the eyelid. Breast cancer was the most frequent original cancer, and about two-thirds of documented preoperative impressions were benign diagnoses. The findings describe reported patterns, but they do not show how often eyelid lesions are metastatic in the general population.
