Abstract

Slip migration must be controlled to maintain the performance and quality of flexible packaging. Inorganic based anti-block materials can be used to control the slip migration. This paper reported the effect of anti-block type on the inhibition of slip migration on polyethylene monolayer film. A series of formulations were made with three different anti-block additives, namely talc, natural silica, and synthetic silica, along with erucamide. The optical properties (haze) and friction properties (COF) were measured to assess the film characteristics as the development of slip migration in the presence of anti-block additives. Characterization of the anti-block material was conducted by SEM-EDX, slip additive type was examined by GC-MS, while the slip content on the surface was analysed by FTIR. The result showed that after seven days, synthetic silica anti-block gives COF up to 0.095, with the trace erucamide content on the film surface of 394 ppm, the lowest amongst other types of the anti-block used. The smaller particle size and higher silica content on synthetic silica anti-block resulted in better friction properties which act as a good barrier to limit a migration of erucamide onto the film surface.

Abstract

Purpose: Retinopathy of prematurity (ROP) is a vaso-proliferative disease of the retina associated with prematurity and is well known to be the leading cause of childhood blindness worldwide. Given the prevalence of ROP and the increasing demand for efficient screening solutions, this systematic review aims to update the current development of Artificial Intelligence (AI) technologies for ROP diagnosis and screening, considering the appropriate AI types that align with the specific needs and workloads of ROP screening programs. Methods: We performed a systematic literature review of the English online literature databases by applying a general search strategy on April 20, 2024. Search phrases included multiple variants of terms including "ROP", "retinopathy of prematurity", "artificial intelligence", "diagnosis", "sensitivity analysis", "specificity", "area under the curve". Findings: A total of 12 studies were identified from varied countries. Summary: Review of the published literature demonstrate high sensitivity across different studies, indicating their strong potential for early detection of ROP but demonstrating variability in specificity. The review also underscores the importance of domain adaptation and validation across diverse populations to ensure generalizability. AI integration in clinical practice, especially in telemedicine, can enhance early detection, standardize diagnoses, and alleviate the burden on healthcare professionals, particularly in low-resource settings.

Abstract

Introduction: The COVID-19 pandemic has forced many conventional -face-to-face health promotion events to be conducted in an adaptive manner to keep healthcare in promotion, prevention, and even curative measures delivered to healthcare providers and patients. The same applies to leprosy, where Indonesia is still ranked as the third largest country with leprosy burden. This study aims to give rise to newer methods of health promotion on leprosy during this COVID-19 pandemic. Methods: Online training and case presentation workshop in the form of a KATAMATAKU webinar [MOU1] and live streaming via YouTube were held in August 2020. There were 120 general practitioners, 30 nurses, and 35 healthcare providers who registered and joined this event.[MOU2]  Pre- and post-test [MOU3] were conducted to evaluate the participants' knowledge about the topics lectured during this training[MOU4] . Pre- and post-test were conducted using an online form, and all participants needed to answer several questions from each session. Participants were evaluated before the webinar began and after all sessions. We assessed the different scores from the pre- and post-test. Results: In the general practitioner group, median scores were 68 (27 – 95) and 82 (50 – 100) for pre- and post-test scores, respectively, with a mean difference between post and pre-test of 14.23+9.72. In nurses and other health care providers, the median for the pre-test score was 56 (22-89), and the post-test was 72 (39 – 100), with a mean difference between the post and pre-test of 18.93+10.27. Conclusion: In the pandemic situation, online seminars can be chosen as an effective method for health promotion to increase health care provider's knowledge. Pre- and post-test can be performed to evaluate participant's knowledge after the training. Regular training using online methods can be held in order to maintain participants' knowledge. We hope it can impact all health providers to continue their participation in the management of leprosy.

Abstract

Leprosy has a high incidence of physical complications that will impact directly the physiological, economic, and social status of patients. Indonesia has a high burden of the disease, and several leprosy settlements are still spread in the country. Neglasari Village, Sitanala, Tangerang serves as one of the places of residence of people who have had leprosy. A health service initiative known as Identifikasi Tanda-Tanda Mata, Ekstremitas, dan Kulit pada Kusta (KATAMATAKU) was launched as a collaboration of health services among multi-departments (ophthalmology, dermatovenereology, and medical rehabilitation). Sitanala has a relatively high incidence of people who have had leprosy with disabilities of the hand, foot, and eye. As a continuation of this health service and combined with the efforts to improve the welfare of leprosy patients, in November 2019, a multidisciplinary program titled KATAMATAKU Universitas Indonesia, was conducted. This program aimed to determine the demographic data regarding the health, psychological, social, and economic status of the leprosy population at Sitanala The project consisted of a collaborative anti-stigma program by the Faculty of Psychology, Public Health, Social and Political Sciences, Cultural Sciences, Administrative Sciences, and Vocational Educational Program; thematic health program, which supports the improvement of physical abilities and empowerment of former leprosy patients, by the Faculty of Medicine, Dentistry, Nursing, and Pharmacy; thematic economics program, which aims to increase the economic capacity of the leprosy community, by the Faculty of Economics and Business, Mathematics and Natural Sciences, and Engineering. This program enabled the construction of a multidimensional management model, in which every aspect plays important roles to improve the patients’ quality of life.
