Analysis of queries about over-the-counter overdosing reveals pervasive abuse

2023-12-22

(Press-News.org) Kyoto, Japan – A non-prescription drug abuse crisis in Japan seems only one overdose away. The demand for a particular anti-cough drug has been rising, along with the social impact of its abuse due to its psychosomatic effects.

The ease of obtaining information online about how to acquire over-the-counter medications or OTCs for achieving overdose, however, does not appear to be the real problem.

Now, a study by a team of researchers at Kyoto University suggests that reliable information about OTC abuse needs to be readily available and effectively disseminated.

"We focused on potential OTC abusers at risk of addiction though they did not show sufficient symptoms to justify or necessitate visits to medical institutions or support facilities," says corresponding author Azusa Kariya of KyotoU's Graduate School of Medicine and School of Public Health.

Users of Japan's largest consumer-generated media -- or CGM -- service, Yahoo! Chiebukuro, post their questions and responses about OTCs primarily to learn more about overdosing, such as access to the drugs, their efficacy and effects, and health risks.

Abuse results from two causes: one is from seeking symptomatic relief from some physical pain and overdosing to the point of addiction. The other occurs when people intentionally overdose to cause either self-harm or psychosomatic changes.

Kariya's team also found that OTC abusers and potential abusers sought advice on quitting their drug addiction on the Yahoo! community website. Most poignantly, the team discovered that OTC overdosers resist consulting others in person, making the CGM a convenient source of anonymously obtained information.

"Our study aims to make sense of our CGM data to identify possible overdosers. We could then be better positioned to cooperate with health professionals and seek support from pharmacies to reduce OTC abuse," adds Kariya.

Kariya's team searched the names of commonly abused OTCs, tracked the keywords overdose and OD, and tallied the number of relevant questions posted on the Yahoo! site.

The number of OD-related queries containing the keyword BRON -- an antitussive and expectorant -- has increased sharply, pointing to the significant impact of community-based websites.

Furthermore, the team extracted 467 items of question data that met the eligibility criteria from 528 items of BRON-tagged text data, generating 26 codes and six categories. Three main themes resulted: expectations for overdose, anxieties about overdose, and troubles in quitting overdose.

"The current crisis that mental health professionals are confronting is just the tip of the iceberg. We must dive below to see the scale of abuse hidden from view," reflects Kariya.

Robots versus humans: Which would children trust more when learning new information?

2023-12-22

In this digital age, children are exposed to overwhelming amounts of information online, some of it unverified and increasingly generated by non-human sources, such as AI-driven language models. As children grow older, the ability to assess a source’s reliability is an important skill in cultivating critical thinking. Children aged three to five years display selective trust based on the informant’s past accuracy when faced with both humans and robots, according to a study published in the journal Child Development titled, ‘Younger, not older, ...

AI tool aids in screening for nerve disorder

2023-12-22

Researchers at the Indian Institute of Science (IISc), in collaboration with Aster-CMI Hospital, have developed an AI tool that can identify the median nerve in ultrasound videos and detect carpal tunnel syndrome (CTS). The study was published in IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control. CTS arises when the median nerve, which runs from the forearm into the hand, is compressed at the carpal tunnel part of the wrist, resulting in numbness, tingling or pain. It ...

Big impacts from small changes in cell

2023-12-22

Tiny things matter – for instance, one amino acid can completely alter the architecture of the cell. Researchers at the Universities of Göttingen and Warwick investigated the structure and mechanics of the main component of the cytoskeleton of the cell: a protein known as actin. Actin is found in all living cells where it has a range of important functions – from muscle contraction to cell signalling and cell shape. This protein comes in two different varieties termed “isoforms”, which are known as gamma actin and beta actin. The difference between the two proteins is ...

Jupiter was targeted by exoplanet hunter

2023-12-22

For the first time, an instrument to find planets light years away was used on an object in the Solar System, in a study on Jupiter's winds. We find ourselves at a time when it has become almost commonplace to discover planets orbiting another star, with more than 5,000 already registered. The first distant worlds to incorporate this list were mainly giant planets, similar to but also very different in many ways from Jupiter and Saturn. Astrophysicists have already begun to obtain data on the atmospheres of exoplanets, but fundamental ...

Pandemic lessons: Insights into how mobility restrictions affect healthcare costs

2023-12-22

Osaka, Japan - As the world grappled with lockdowns and restrictions brought by the COVID-19 pandemic, researchers at Osaka Metropolitan University conducted an extensive study to elucidate the link between changes in human mobility and the impact on medical costs associated with lifestyle-related diseases. Dr. Haruka Kato and Professor Atsushi Takizawa of the Graduate School of Human Life and Ecology at Osaka Metropolitan University were concerned by the negative health effects resulting from the restriction of ...

Controlling thermoelectric conversion in magnetic materials by magnetization direction

2023-12-22

1. NIMS has succeeded in directly observing the "anisotropic magneto-Thomson effect," a phenomenon in which the heat absorption/release proportional to an applied temperature difference and charge current (i.e., Thomson effect) changes anisotropically depending on the magnetization direction in magnetic materials. This research is expected to lead to further development of basic physics and materials science related to the fusion area of thermoelectrics and spintronics, as well as to development of new functionalities to control thermal energy with magnetism. 2. The Thomson effect has long been known as one of the fundamental ...

Stinky, bitter, and painful: A novel insect repellent attacks multiple sensory pathways

2023-12-22

Okazaki, Japan – crop damage in agriculture and the transmission of vector-borne diseases by insect pests have become worldwide threat nowadays. Chemical treatments such as insecticides and repellents have been a major strategy against insect pests for centuries. Due to limited understanding of mechanisms of insect avoidance behavior, however, development of insect repellents has been delayed. To discover compounds that effectively repel insect pests, it is important to focus on key molecules associated with sensory, particularly aversive, responses. In this study, researchers ...

Microglia act as a “facilitator and stabilizer” for anesthesia

2023-12-22

Though it may be a surprise to the millions of people who undergo general anesthesia every year for medical procedures, the biological mechanism for how different anesthetics block consciousness is still not fully understood. However, researchers may be one step closer after uncovering the way small immune cells in the brain called microglia are impacted by general anesthesia. The research was presented in a paper published in eLife on 22/Dec/2023. “We found that microglia play an important role in regulating the body’s response to general anesthesia. ...

3D-printed flat-bone-mimetic bioceramic scaffolds for cranial restoration

2023-12-22

The cranial bone in the human body performs very important functions, such as protecting the brain and enabling the passage of the cranial nerves that are essential to physiological functioning. Critical-sized cranial defects can disrupt both the physical and psychological well-being of patients. Restoration of critical-sized cranial defects by cranioplasty is challenging for reconstructive surgeons, who prefer to use autologous bone grafts. The acquisition of autologous bone requires additional surgeries concomitant with risks such as free flap loss, infection, deep venous thrombosis, and nerve injury. These limitations necessitate the development ...
