Abstract : The Covid-19 pandemic caused a downturn in the industrial sectors in Indonesia, including the construction sector, forcing all stakeholders to work together to stop the spread of the pandemic while maintaining business continuity amid Indonesia's massive infrastructure development. The pandemic has also limited monitoring and evaluation of the implementation of OHS procedures in construction projects due to pandemic-related limitations. Therefore, digital technology should be enforced to support accurate OHS reporting effectively, efficiently, and in real-time. This study focuses on using IT and the conformity of RCA implementation in monitoring and evaluating OHS implementation in construction sites. This study used a survey to collect responses from a sample of the person in charge of OHS implementation at a major Indonesian construction company, PT. Wijaya Karya (Persero) Tbk. The data were then analyzed using descriptive and inferential statistical methods: linearity, regression, and correlation tests between variables. The results show that the current RCA implementation has yet to represent the actual circumstances in the sites and that online monthly reporting is linked to IT usage through the online RCA platform. Through this study, the reporting of OHS implementation using information technology can be improved to improve the quality of OHS implementation itself.

Abstract : This study aimed to evaluate the remineralization potential BioMin-F compared to a commonly used standard toothpaste (Signal®) in primary teeth. Thirteen enamel blocks of primary canines were divided randomly into two groups: Group 1 (n = 15; Experimental), BioMin-F toothpaste group, and Group 2: (n = 15; Control), Signal toothpaste. The samples were initially evaluated for baseline surface microhardness; later on, these samples were placed in the demineralizing solution for 69 h, and post-demineralization surface microhardness was measured. Thereafter, the samples were stored in the toothpaste for 3 minutes twice daily for 15 days, and surface microhardness was recorded. The surface microhardness was evaluated using a Vickers microhardness tester. Statistical analysis was done using dependent and independent sample tests. The results showed that there is a statistically significant difference in the mean enamel microhardness after remineralization (p=0.000) between the BioMin-F (353.62) and Signal (300.62) groups in favor of the BioMin-F group. The BioMin-F toothpaste showed promising potential to promote remineralization of demineralized primary human enamel.

Abstract : Coronary artery disease (CAD) is a primary contributor to cardiovascular disease burden, with India having about 29.8 million CAD cases in a population of 1.03 billion, a 3% prevalence. Chronic Total Occlusion (CTO) poses challenges for cardiologists due to complexities, leading to lower success rates compared to non-occluded artery procedures. This prospective observational study aimed to analyze the clinical, risk factors, and echocardiographic profiles of patients with coronary chronic total occlusions (CTOs). It examined angiographic details, quantified disease severity using the SYNTAX score, and assessed technical challenges with the J-CTO score. The research also investigated management patterns and outcomes for CTO patients. Among the 66 enrolled CTO patients, the majority (89%) were males with an average age of 56. Most (72%) had angina class II or higher, and common comorbidities included hypertension (54%) and diabetes (39%). Approximately 82% had multivessel coronary artery disease (CAD), with nearly 80% having SYNTAX scores ≥23. The right coronary artery (RCA) was frequently involved. Percutaneous coronary intervention (PCI) was performed in 57% of cases, while 30% underwent coronary artery bypass grafting (CABG), and 12% received medical management. The predominant CTO-PCI technique was antegrade wire escalation, with polymer-jacketed wires like Fielder XT-A and GAIA II being commonly used. After a three-month follow-up, patients in the revascularization group reported symptom improvement. Notably, male gender, RCA territory CTO, a JCTO score of ≤1, and a SYNTAX score <31.5 were significant predictors of successful PCI outcomes. This study provides valuable insights into coronary CTOs, highlighting factors that influence revascularization success. It suggests potential benefits of intervention within three months in the context of interventional cardiology at a high-volume center in western India. The combined use of J-CTO and SYNTAX scoring systems is recommended for predicting procedural outcomes and technical challenges during PCI.

Abstract : This study aimed to evaluate the remineralization potential of sodium monofluorophosphate (NovaMin®) compared to a commonly used standard toothpaste (Signal®). Thirteen enamel blocks of primary canines were divided randomly into two groups: Group 1 (n = 15; Experimental), NovaMin® toothpaste group, and Group 2: (n = 15; Control), Signal® toothpaste. The samples were initially evaluated for baseline surface microhardness; later on, these samples were placed in the demineralizing solution for 69 h, and post-demineralization surface microhardness was measured. Thereafter, the samples were stored in the toothpaste for 3 minutes twice daily for 15 days, and surface microhardness was recorded. The surface microhardness was evaluated using a Vickers microhardness tester. Statistical analysis was done using dependent and independent sample tests. The results showed that there is a statistically significant difference in the mean enamel microhardness after remineralization (p=0.000) between the NovaMin (399.99) and Signal (300.62) groups in favor of the NovaMin group. The NovaMin toothpaste showed promising potential to promote remineralization of demineralized human enamel.

Abstract : Infertility is a growing health problem around the world, and the reasons for its increasing rates in recent years are still poorly understood. Obesity is currently one of the biggest global health challenges due to its rapid spread and its association with many chronic diseases such as cardiovascular disease and type 2 diabetes. Studies have also shown that obesity is associated with sexual dysfunction in both sexes. Several studies suggested the positive impact of bariatric surgery on testosterone and estradiol impairments, but their results were contradictory. Thus, we aimed in the current study to evaluate the impact of bariatric surgeries on testosterone and estradiol levels. The current prospective study included 66 obese patients with morbid obesity who all underwent bariatric surgery. Testosterone and estradiol concentrations were measured in these patients before surgery and at three, six, and 12 months after the procedure. Our results showed that bariatric surgery resulted in a statistically significant reduction in BMI from 51.3 ± 12.1 to 33.53 ± 7.7 one year after the surgery. In addition, testosterone levels significantly increased from 3.27 ± 1.25 ng/ml to 4 ± 1.14 ng/ml a 12 month post-operatively. However, estradiol levels declined after the surgery but without significant difference. In conclusion, bariatric surgery is effective in reduction BMI and increasing testosterone levels in morbidly obese men underwent bariatric surgery.
