Published: April 2024

Background
During the COVID-19 pandemic period, it was difficult to carry out regular and scheduled follow-up of patients in the outpatient department, especially during lockdown periods. However, early detection of initial infection or other serious conditions is vital for patients after ocular surgery, such as intravitreal injection (IVI) for age-related macular degeneration (AMD).

Objective
We evaluated the use of a smartphone-based postoperative care chatbot system (PCCS) with an instant bidirectional feedback system for patients to self-report postoperative symptoms and signs.

Methods
During the COVID-19 level 3 epidemic alert in July 2021 in Taiwan, the PCCS alerted the patients to report and grade 6 ocular symptoms and signs associated with ocular inflammation or retinal detachment. Patients used the PCCS for 7 days post surgery to assess their symptoms and signs each day after receiving an alert. Data were automatically collected using a cloud computer system, including symptom grades and messages sent to medical staff for further medical assistance. A user satisfaction questionnaire was administered to the patients on the seventh day post surgery.

Results
In total, 185 patients participated in this study. There were 26 (3.03%) reports of symptom grade deterioration (including increased blurred vision, eye swelling, nausea, and floaters or flashes) from 12 (6.5%) patients. We found no difference in the gender of patients who received an early medical consultation. One case of endophthalmitis was reported, wherein an improvement was observed after prompt administration of IVI antibiotics twice. Overall, 87% (n=185) of patients were satisfied or very satisfied with communicating their symptoms instantly through the app; they were willing to use it again and believed that it could improve the quality of care. Seven of the 185 (3.8%) patients had an earlier medical consultation and 1 (0.5%) had endophthalmitis.

Conclusions
The chatbot system, designed for self-reporting postoperative symptoms and providing instant bidirectional feedback on smartphones, could be beneficial for enhancing the quality of care in early medical consultations without gender differences among patients with AMD receiving IVI, and achieved satisfactory responses from patients.
How to Elucidate Consent-Free Research Use of Medical Data: A Case for “Health Data Literacy”
Authors: Richter Gesine , Krawczak Michael 
Published: April 2024

AbstractThe extensive utilization of personal health data is one of the key success factors of modern medical research. Obtaining consent to the use of such data during clinical care, however, bears the risk of low and unequal approval rates and risk of consequent methodological problems in the scientific use of the data. In view of these shortcomings, and of the proven willingness of people to contribute to medical research by sharing personal health data, the paradigm of informed consent needs to be reconsidered. The European General Data Protection Regulation gives the European member states considerable leeway with regard to permitting the research use of health data without consent. Following this approach would however require alternative offers of information that compensate for the lack of direct communication with experts during medical care. We therefore introduce the concept of “health data literacy,” defined as the capacity to find, understand, and evaluate information about the risks and benefits of the research use of personal health data and to act accordingly. Specifically, health data literacy includes basic knowledge about the goals and methods of data-rich medical research and about the possibilities and limits of data protection. Although the responsibility for developing the necessary resources lies primarily with those directly involved in data-rich medical research, improving health data literacy should ultimately be of concern to everyone interested in the success of this type of research.

Published: April 2024

Abstract

Background
Information about the range of Hounsfield values for healthy teeth tissues could become an additional tool in assessing dental health and could be used, among other data, for subsequent machine learning.

Objective
The purpose of our study was to determine dental tissue densities in Hounsfield units (HU).

Methods
The total sample included 36 healthy children (n=21, 58% girls and n=15, 42% boys) aged 10-11 years at the time of the study. The densities of 320 teeth tissues were analyzed. Data were expressed as means and SDs. The significance was determined using the Student (1-tailed) t test. The statistical significance was set at P<.05.

Results
The densities of 320 teeth tissues were analyzed: 72 (22.5%) first permanent molars, 72 (22.5%) permanent central incisors, 27 (8.4%) second primary molars, 40 (12.5%) tooth germs of second premolars, 37 (11.6%) second premolars, 9 (2.8%) second permanent molars, and 63 (19.7%) tooth germs of second permanent molars. The analysis of the data showed that tissues of healthy teeth in children have different density ranges: enamel, from mean 2954.69 (SD 223.77) HU to mean 2071.00 (SD 222.86) HU; dentin, from mean 1899.23 (SD 145.94) HU to mean 1323.10 (SD 201.67) HU; and pulp, from mean 420.29 (SD 196.47) HU to mean 183.63 (SD 97.59) HU. The tissues (enamel and dentin) of permanent central incisors in the mandible and maxilla had the highest mean densities. No gender differences concerning the density of dental tissues were reliably identified.

Conclusions
The evaluation of Hounsfield values for dental tissues can be used as an objective method for assessing their densities. If the determined densities of the enamel, dentin, and pulp of the tooth do not correspond to the range of values for healthy tooth tissues, then it may indicate a pathology.

Published: April 2024

Objective: The aim of this study was to assess the effectiveness of classification-based approach for low back pain care in Finnish primary care.
Design: A benchmarking controlled trial design was used.
Subjects/patients: Three primary healthcare areas and 654 low back pain patients with or without sciatica.
Methods: Classification-based care (using the STarT Back Tool) was implemented using organizational-, healthcare professional-, and patient-level interventions. The primary outcome was change in Patient-Reported Outcomes Measurement Information System, Physical Function (PROMIS PF-20) from baseline to 12 months.
Results: No difference was found between the intervention and control in change in PROMIS PF-20 over the 12-month follow-up (mean difference 0.33 confidence interval –2.27 to 2.9, p = 0.473). Low back pain-related healthcare use, imaging, and sick leave days were significantly lower in the intervention group. Reduction in intensity of low back pain appeared to be already achieved at the 3-month follow-up (mean difference –1.3, confidence interval –2.1 to –0.5) in the intervention group, while in the control group the same level of reduction was observed at 12 months (mean difference 0.7, confidence interval –0.2 to 1.5, treatment*time p = 0.003).
Conclusion: Although classification-based care did not appear to influence physical functioning, more rapid reductions in pain intensity and reductions in healthcare use and sick leave days were observed in the intervention group.

Objectives:
To evaluate and compare the Salt perception threshold and vascular stiffness in pre-hypertensive women with that of normotensive and hypertensive women.

Materials and Methods:
Study design – This was a cross-sectional study. A total of 440 adult females in the age group of 25–60 years from urban and rural areas were included in the study. After initial screening, the subjects were divided into three groups. Group I: Prehypertensive females; Group II: Hypertensive females; and Group III: Normotensive females. Salt perception threshold was determined by salt impregnated taste strips with sodium chloride at different concentrations. Vascular stiffness of the subjects was measured and compared using an oscillometric non-invasive arteriography.

Results:
The salt intake was higher by 2.1 g/day in Group I females and 5.6 g/day in Group II females when compared to Group III females. The salt detection threshold and SPT were higher significantly in pre-hypertensive females and much higher in hypertensive females compared to normotensive females. The mean values of brachial ankle pulse wave velocity (BaPWV) and carotid femoral pulse wave velocity (CFPWV) were found to be significantly higher in Group I females compared to normotensives.

Conclusion:
High SPT in prehypertensive females will lead to high consumption of salt to achieve taste satisfaction. A progressive reduction of salt in food is recommended in these females would significantly decrease the percent progression of pre-HTN to HTN decreasing the risk for cardiovascular morbidity.

This article explains about the Covid-19 crisis that afflicted the Indonesian people on the one hand and the incompetence of the Joko Widodo government (regime) in dealing with it has put the regime in a defensive position on the other hand. Indeed covid-19 is produced by nature. But the regime did not immediately deal with it until about two months later, a period of gold wasted. Though this virus spread very quickly. Lockdown which is the most rational choice as applied by many countries to break the chain of transmission is not a regime option. The reason was that the regime did not want to feed the people living in areas that were locked down or quarantined. Not surprisingly, the people sued for the inaction of the regime to deal with it. Meanwhile, to this day the regime also has not yet provided adequate therapy to prevent more people from falling victim. In fact, officials from the beginning made statements that seemed to play with this dangerous disease. After a hard protest and lawsuit from within and outside the country, Jokowi admitted that his regime deliberately covered up the truth so that the people would not panic. Despite acknowledging mistakes and trying to seriously handle them, the policies taken are inadequate, fickle, and overlapping.

Published: April 2024

Dalam penelitian mengidentifikasi pengaruh ukuran buffer dalam proses duplikasi file dengan ukuran file 1 gigabyte (GB) dan menggunakan sistem file tmpfs. Baseline code menggunakan operasi tingkat-rendah (low-level operation) seperti open(), creat(), read(), dan write(). Penelitian ini bertujuan untuk mengoptimasi proses duplikasi file menggunakan tiga metode. Pada tahap awal, penulis mengidenfikasi beberapa isu yang terdapat pada operasi read/write pada sistem file linux. Terdapat tiga metode yang akan diinvestgasi dalam penelitian ini, pertama, meningkatkan ukuran buffer, kedua membandingkan fungsi creat() dan open(), ketiga menganalisa fungsi O_Direct() pada tmpfs. Untuk duplikasi file, ukuran buffer menjadi hambatan kinerja pada proses sistem file ini. Karena jumlah read() tergantung pada ukuran buffer, sehingga operasi baca-tulis terus beralih antara mode pengguna dan mode kernel.

Saat ini beton banyak mengalami inovasi untuk menghasilkan beton yang lebih baik dan ramah lingkungan. Beton telah banyak dimodifikasi dengan mencampurkan berbagai agregat buatan sebagai pengganti agregat kasar, salah satunya yaitu penggunaan tanah diatomae. Tujuan dari penelitian ini untuk mengetahui pengaruh penggunaan tanah diatomae sebagai agregat buatan terhadap kuat tekan beton. Metode campuran beton yang digunakan pada penelitian ini mengikuti aturan berdasarkan SNI 7656-2012. Substitusi agregat buatan dibuat dengan persentase 25%, 50%, 75%, dan 100% terhadap berat volume absolut kerikil. Benda uji dibuat sebanyak 20 sampel berbentuk silinder berukuran 10 x 20 cm dengan umur beton 28 hari. Agregat buatan memiliki berat jenis 1,964 kg/m3, penyerapan air (absorpsi) 12,360%, dan berat volume padat 1201 kg/m3. Hasil pengujian kuat tekan beton campuran agregat buatan mengalami persentase penurunan sebesar 13,86%-37,02% dari kuat tekan beton normal. Sedangkan untuk berat isi beton mengalami penurunan sebesar 6,105% - 16,68%. Penyerapan air agregat kasar buatan yang cukup besar mempengaruhi mutu agregat, namun pada penggunaannya juga mengurangi berat isi dari beton itu sendiri.

Waktu istirahat bayi iyalah saat ia tertidur, maka dari itu perlunya perhatian khusus untuk kenyamanan tempat tidur bayi yang biasanya pada ayunan. Permasalahan yang sering muncul ialah pada kaum ibu biasanya tidak jauh dengan kegiatan rumahan seperti memasak dan lain-lain. Ibu-ibu yang memiliki bayi berusia 0 sampai dengan 6 bulan tidak dapat jauh dari bayinya dikarenakan harus menidurkan bayinya untuk dapat melakukan pekerjaan lain. Maka dari itu dibuatlah alat yang menjadi solusi dari permasalahan tersebut. Alat yang dibuat bertujuan mengayunkan bayi secara otomatis sehingga ibu dapat melakukan pekerjaan lain dengan tetap memonitor bayi saat teridur. Jaringan internet sangat berguna untuk melakukan pengontrolan pada bayi saat ibunya melakukan pekerjaanseperti memasak maupun lainya. Ayunan bayi otomatis yang dibuat menggunakan sistem kontrol pergerakan, suara, maupun saat bayi buang air. Sensor yang digunakan ialah PIR, Suara dan MQ-2. Penggunaan mikrokontroler sisesuaikan dengan kebutuhan, dikarenakan menggunakan teknologi Internet of Things maka ESP32 yang berperan melakukan eksekusi program sesuai dengan algoritma yang di tanamkan pada modul tersebut. Pengujian yang dilakukan pada sensor PIR dan sensor suara dalam mendeteksi pergerakan objek dan suara berdasarkan jarak kerja sensor. Pada jarak kerja 0 sampai engan 1 meter dari sensor pergerakan objek terdeteksi, jarak kerja 1 sampai dengan 2 meter sensor masih mendeteksi adanya pergerakan objek, sensor tidak mendeteksi saat pergerakan objek di atas 5 meter jarak kerja, dikarenakan sudah melebihi jarak kerja maksimal untuk sensor PIR. Akan tetapi sensor suara masih mendeteksi suara dalam jarak 5 sampai dengan 6 meter, jarak kerja sensor suara lebih jauh jangkauannya dibandingkan sensor PIR.
