Health experts are urging for heightened public awareness and the dispelling of misconceptions to improve the coverage rate of the human papillomavirus (HPV) vaccine in China. HPV, a leading cause of cervical cancer, claimed 350,000 lives globally in 2022, with China accounting for 16% of these fatalities. Starting November 10, China will integrate the HPV vaccine into its national immunization program, offering free bivalent HPV vaccines to girls aged 13 and above born after November 10, 2011. This marks a significant shift from previous policies that targeted children under six, now extending to adolescents and focusing on preventing a malignant tumor caused by chronic infection, particularly in women. Du Heng of the Gates Foundation emphasized the long-term impact of this initiative, noting that full outcomes may take 20 to 30 years to manifest. As of June, 18 provincial-level regions in China have already provided free HPV vaccinations to about 5 million girls annually, targeting those aged 9 to 14. In Beijing, for instance, girls in the 7th grade and above can receive free domestically developed bivalent vaccines, which protect against the two most common HPV strains responsible for 70-80% of cervical cancers. Despite these efforts, some parents remain hesitant, citing concerns about the necessity and safety of the vaccine. However, experts like Qiao Youlin from Peking Union Medical College believe that these challenges are temporary and will improve with increased health awareness. The World Health Organization aims for 90% of girls globally to be fully vaccinated against HPV by the age of 15 by 2030, as part of its strategy to eliminate cervical cancer. In China, the free vaccination policy has already covered many eligible girls, showcasing significant progress. Experts also stress the importance of regular cervical cancer screenings and the role of men in HPV prevention, as their infection rate is as high as 45%, often without symptoms. Eliminating cervical cancer is seen as a shared societal responsibility, achievable through enhanced scientific awareness and collective action.

A groundbreaking study published in the international journal *Nature Cardiovascular Research* highlights that women may experience significantly greater cardiovascular benefits from exercise compared to men. Conducted by a collaborative team led by Professor Wang Yan and Associate Researcher Chen Jiajin from Xiamen Cardiovascular Hospital Xiamen University and Shanghai Chest Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, the research analyzed wearable device data from 85,000 participants. The findings reveal that women need only 250 minutes of weekly exercise to reduce their risk of coronary heart disease by 30%, whereas men require 530 minutes to achieve the same level of protection. For individuals already diagnosed with coronary heart disease, women exercising 51 minutes weekly can lower their mortality risk by 30%, while men need 85 minutes for similar results. Coronary heart disease remains a leading cause of death globally, with organizations like the World Health Organization recommending at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity weekly activity for adults. The study challenges the ‘one-size-fits-all’ approach to exercise guidelines, advocating for gender-specific recommendations to optimize heart disease prevention and treatment.

Jakarta, Indonesia, is grappling with a significant environmental and public health crisis as microplastics contaminate its air and water. A 2022 study by the National Research and Innovation Agency (BRIN), published in the Marine Pollution Bulletin, revealed the presence of microplastics in rainwater samples collected across the city. These tiny plastic particles, ranging from 1 nanometer to 5 millimeters in size, originate from both household and industrial sources, indicating widespread atmospheric contamination. The study also found that the deposition rate of microplastics increases during the rainy season, exacerbating the issue. In response, the Jakarta Environment Agency has pledged to enhance plastic waste management and reduce single-use plastics. Agency head Asep Kuswanto emphasized the urgency of addressing this ‘environmental warning,’ noting that plastic pollution has now permeated the skies above Jakarta. Researchers, led by Muhammad Reza Cordova, observed microplastics as small as 0.3 to 0.5 millimeters in rainwater samples from North Jakarta. Reza warned that the situation may worsen due to rising plastic consumption, particularly during the dry season when rainfall is scarce. The health implications of microplastic exposure are severe, with potential risks including inflammation, respiratory illnesses, and even cancer. A 2024 Cornell University study highlighted that Indonesians ingest an alarming 15 grams of microplastics monthly, the highest globally. Coastal communities, heavily reliant on seafood, are particularly vulnerable. Despite these risks, many fishermen remain unaware of the dangers, continuing to consume fish from polluted waters. Yuyun Ismawati, co-chair of the International Pollutants Elimination Network, criticized the government for prioritizing industrial investments over public health, urging stricter pollution monitoring and waste import regulations. The Jakarta administration has begun expanding its monitoring systems to trace microplastics in the air and rainwater, but the long-term health and environmental impacts remain a pressing concern.
