Published: July 2020

Background
High-quality medical resources are in high demand worldwide, and the application of artificial intelligence (AI) in medical care may help alleviate the crisis related to this shortage. The development of the medical AI industry depends to a certain extent on whether industry experts have a comprehensive understanding of the public’s views on medical AI. Currently, the opinions of the general public on this matter remain unclear.

Objective
The purpose of this study is to explore the public perception of AI in medical care through a content analysis of social media data, including specific topics that the public is concerned about; public attitudes toward AI in medical care and the reasons for them; and public opinion on whether AI can replace human doctors.

Methods
Through an application programming interface, we collected a data set from the Sina Weibo platform comprising more than 16 million users throughout China by crawling all public posts from January to December 2017. Based on this data set, we identified 2315 posts related to AI in medical care and classified them through content analysis.

Results
Among the 2315 identified posts, we found three types of AI topics discussed on the platform: (1) technology and application (n=987, 42.63%), (2) industry development (n=706, 30.50%), and (3) impact on society (n=622, 26.87%). Out of 956 posts where public attitudes were expressed, 59.4% (n=568), 34.4% (n=329), and 6.2% (n=59) of the posts expressed positive, neutral, and negative attitudes, respectively. The immaturity of AI technology (27/59, 46%) and a distrust of related companies (n=15, 25%) were the two main reasons for the negative attitudes. Across 200 posts that mentioned public attitudes toward replacing human doctors with AI, 47.5% (n=95) and 32.5% (n=65) of the posts expressed that AI would completely or partially replace human doctors, respectively. In comparison, 20.0% (n=40) of the posts expressed that AI would not replace human doctors.

Conclusions
Our findings indicate that people are most concerned about AI technology and applications. Generally, the majority of people held positive attitudes and believed that AI doctors would completely or partially replace human ones. Compared with previous studies on medical doctors, the general public has a more positive attitude toward medical AI. Lack of trust in AI and the absence of the humanistic care factor are essential reasons why some people still have a negative attitude toward medical AI. We suggest that practitioners may need to pay more attention to promoting the credibility of technology companies and meeting patients’ emotional needs instead of focusing merely on technical issues.

Hal yang melatar belakangi penelitian ini adalah banyaknya anak usia 5-6 tahun di kelas B3 TK Dharma Wanita Mendalo Darat yang penguasaan kosakatanya belum mencapai indikator keberhasilan sesuai tahapan usianya. Berdasarkan hasil observasi awal, diperlukan adanya penelitian tindakan kelas yang bertujuan untuk meningkatkan penguasaan kosakata anak melalui permainan scrabble. Permainan scrabble dimainkan dengan aturan yang telah ditetapkan dan telah dimodifikasi sesuai dengan tema. Kemudian anak diperdengarkan rekaman suara sesuai tema dan anak ikut bernyanyi dengan tujuan anak dapat mengingat kata yang akan disusunnya. Setelah permainan selesai, dilanjutkan dengan tanya jawab antara anak dan guru tentang materi yang telah dimainkan oleh anak. Penelitian ini menggunakan jenis penelitian tindakan kelas. Menurut Daryanto (2014) bahwa PTK merupakan penelitian yang dilakukan oleh guru di dalam kelas dan melalui refleksi diri yang bertujuan untuk memperbaiki kualitas pembelajaran di kelas, sehingga hasil belajar anak dapat ditingkatkan. Teknik pengumpulan data menggunakan dokumentasi dan lembar observasi. Penguasaan kosakata anak sebelum adanya tindakan masih belum berkembang dengan baik dengan nilai 25,23% dalam kategori sangat tidak setuju. Setelah dilakukan penelitian pada siklus I dengan menggunakan permainan scrabble mengalami peningkatan pada pertemuan IV menjadi 72,19%. Penguasaan kosakata anak telah mengalami peningkatan namun belum mencapai ketuntasan yang telah ditetapkan sehingga dilanjutkan siklus II. Siklus II menggunakan media pendukung berupa iringan musik rekaman suara sesuai dengan kata pada scrabble dan pemberian reward hingga pertemuan IV dan mengalami peningkatan sebesar 88,57% dan telah melampaui batas ketuntasan yaitu 80%, oleh karena itu penelitian dihentikan pada siklus II.

Published: July 2020

OBJECTIVE
A major obstacle in optimizing the performance of closed-loop automated insulin delivery systems has been the delay in insulin absorption and action that results from the subcutaneous (SC) route of insulin delivery leading to exaggerated postmeal hyperglycemic excursions. We aimed to investigate the effect of Afrezza inhaled insulin with ultrafast-in and -out action profile on improving postprandial blood glucose control during hybrid closed-loop (HCL) treatment in young adults with type 1 diabetes.

RESEARCH DESIGN AND METHODS
We conducted an inpatient, three-way, randomized crossover standardized meal study to assess the efficacy and safety of Afrezza at a low (AL) and a high (AH) dose as compared with a standard SC rapid-acting insulin (aspart) premeal bolus during Diabetes Assistant (DiAs) HCL treatment. Participants received two sequential meals on three study days, and premeal insulin bolus was determined based on home insulin-to-carbohydrate ratio for each meal (rounded up to the closest available Afrezza cartridge dose for AH and down for AL). The primary efficacy outcome was the peak postprandial plasma glucose (PPG) level calculated by pooling data for up to 4 h after the start of each meal. Secondary outcomes included hyperglycemic, hypoglycemic, and euglycemic venous glucose metrics.

RESULTS
The mean ± SD PPG for the rapid-acting insulin control arm and AH was similar (185 ± 50 mg/dL vs. 195 ± 46 mg/dL, respectively; P = 0.45), while it was higher for meals using AL (208 ± 54 mg/dL, P = 0.04). The AH achieved significantly lower early PPG level than the control arm (30 min; P &lt; 0.001), and improvement in PPG waned at later time points (120 and 180 min; P = 0.02) coinciding with the end of Afrezza glucodynamic action.

CONCLUSIONS
Afrezza (AH) premeal bolus reduced the early glycemic excursion and improved PPG during HCL compared with aspart premeal bolus. The improvement in PPG was not sustained after the end of Afrezza glucodynamic action at 120 min.
