Effective malaria prevention in pregnant women despite drug resistance
A study in southern Mozambique found that sulfadoxine-pyrimethamine (SP) remains effective for preventing malaria infections in pregnant women, even in areas with high drug resistance. The study showed increased clearance of P. falciparum infections and lower antibodies resulting from parasite colonisation.
“From Osimertinib to Preemptive Combinations” by Dr. Blagosklonny
Researchers propose combining osimertinib with gefitinib to increase progression-free survival rates in EGFR-mutant lung cancer patients. A comprehensive PC approach could dramatically boost PFS for 80% of patients, eliminating harm and improving treatment outcomes.
As cancer therapies improve, more patients with rectal cancer forego surgery
A growing number of rectal cancer patients are choosing a watch-and-wait approach over surgery, with the number increasing nearly 10% between 2006 and 2020. This approach requires frequent follow-ups but may allow patients to avoid long-term bowel dysfunction.
Natural molecule enhances sunscreen efficacy without increasing concentration of conventional UV filters
A study found that adding rosmarinic acid to sunscreen increases sun protection factor by over 41% and reduces the need for synthetic chemicals. The natural antioxidant also provides anti-aging benefits, making it a potential multifunctional compound for improved skin health.
Breast cancer risk models may incorrectly classify many women
A recent study found that breast cancer risk models can lead to vastly different recommendations for individual women, depending on the model used and threshold applied. The study highlighted the importance of considering both sensitivity and inaccurate classification when using these models.
Actinidia arguta (sarunashi) juice inhibits lung cancer in mice
Researchers from Okayama University found that Actinidia arguta (Sarunashi) juice and its component isoquercetin inhibit lung cancer development in mice, accelerating DNA repair and suppressing Akt-mediated growth signaling. The study suggests Sarunashi juice as an attractive candidate for chemoprevention.
Oncotarget: Ibuprofen disrupts protein complex in colorectal cells
Researchers found that ibuprofen inhibits the alternative splicing event generating RAC1B, overexpressed in BRAF-mutated colorectal tumors. Ibuprofen disrupts a WNK1/GSK3β/SRPK1 protein kinase complex, promoting nuclear exclusion of SRPK1 and SRSF1.
Leprosy declines in Morocco after implementation of preventive drug
Since 2012, the number of leprosy cases in Morocco has decreased significantly, with an average annual decline of -16.83%. This improvement is attributed to the implementation of single dose rifampicin chemoprophylaxis, which has helped to interrupt transmission and reduce disability.
HIV: The benefits of prophylaxis of tuberculosis are confirmed
Long-term follow-up confirms that isoniazid prophylaxis reduces both severe morbidity and mortality among HIV-infected individuals. The study provides evidence for the WHO recommendation of isoniazid preventive therapy in HIV-positive patients, even with early antiretroviral treatment.
Seasonal malaria chemoprevention in Senegalese children lowers overall malaria burden
A randomized trial found that preventive antimalarial drugs for children up to 10 years old reduced malaria cases and deaths, especially among older children. The study also showed a significant reduction in severe malaria incidence.
Target for lung cancer chemoprevention identified
Researchers have identified a biomarker for measuring the success of lung cancer chemoprevention, using abnormal cell development (endobronchial dysplasia). The study found that measurements of endobronchial dysplasia can predict how well a chemoprevention agent is working in former smokers.
Paired drugs kill precancerous colon polyps, spare normal tissue
A combination of Vitamin A acetate and TRAIL kills precancerous colon polyps while sparing normal tissue, providing a potential new avenue for chemoprevention. The regimen, tested in mouse models and human colon cancer tissue, appears to address the issue of continuous long-term therapy required for current chemopreventive drugs.
Is short-term Celecoxib intervention a effective method for preventing gastric carcinogenesis?
A new study found that short-term Celecoxib intervention can effectively prevent gastric carcinogenesis in Mongolian gerbils. The research team suggests that COX-2 inhibitors may be used as chemoprevention for people older than 40 years old, especially those with refractory H. pylori infections at high risk of gastric cancer.
