    Tujuan penelitian ini adalah merancang alat peraga sederhana untuk mencegah kesetrum pada praktikum instalasi listrik bertegangan 220 volt yang terkesan natural. Penelitian ini adalah penelitian eksperimen laboratorium terhadap rancangan rangkaian 2 (dua) trafo step-down 2 Ampere bekas. Hasil penelitian menunjukkan bahwa trafo 1 step-down yang digunakan untuk menurunkan tegangan listrik 220 volt menjadi 12 volt yang dirangkai secara seri dengan trafo 2 yang diposisikan sebagai tafo step-up yang menaikkan tegangan listrik 12 volt menjadi 220 volt dapat menghasilkan tegangan listrik keluaran sebesar 220 volt. Keluaran trafo 2 sebesar 220 volt telah dapat menyalakan lampu 5W/220V dan tidak menyebabkan kesetrum ketika setiap bagian rangkaian tersebut dipegang secara langsung oleh praktikan. Rangkaian 2 trafo tersebut yang menghasilkan tegangan 220 volt dan menyebabkan tidak kesetrum ini dinamakan Trafasi-220. Simpulan penelitian ini adalah rancangan Trafasi-220 sederhana dapat mencegah kesetrum dan dapat dipergunakan siswa secara aman dalam praktikum instalasi listrik bertegangan 220 volt.Saran penelitian ini adalah perlu dilakukan penelitian tentang pengaruh penggunaan Trafasi-220 sederhana ini terhadap peningkatan keberanian siswa dalam praktikum instalasi listrik pada mata pelajaran Keterampilan Elektro

    Prioritising the most needed paediatric antiretroviral formulations: the PADO4 list

    Despite considerable progress in paediatric HIV treatment and timely revision of global policies recommending the use of more effective and tolerable antiretroviral regimens, optimal antiretroviral formulations for infants, children, and adolescents remain limited. The Paediatric Antiretroviral Drug Optimization group reviews medium-term and long-term priorities for antiretroviral drug development to guide industry and other stakeholders on formulations most needed for low-income and middle-income countries. The group convened in December, 2018, to assess progress since the previous meeting and update the list of priority formulations. Issues relating to drug optimisation for neonatal prophylaxis and paediatric treatment, and those relating to the investigation of novel antiretrovirals in adolescents and pregnant and lactating women were also discussed. Continued focus on identifying, prioritising, and providing access to optimal antiretroviral formulations suitable for infants, children, and adolescents is key to ensuring that global HIV treatment targets can be met

    A case report and short review on changing trends in the site of occurrence of adenomatoid odontogenic tumor: Unravelling the past 15 years

    Adenomatoid odontogenic tumor (AOT) is an uncommon benign odontogenic lesion, with debatable histogenesis and variable histopathology. A systematic and diverse insight into the evolution, clinical presentation, histology, and immunohistochemical findings of this lesion is reviewed and presented. We reviewed the data published from 2000 to 2014 of approximately 255 cases that revealed a significant change in the incidence of predominant site involved, in contrast to the findings published by Reichart. We have also included the chronological order of events leading to the coining of the term AOT, which shows the curiosity that has been dedicated to understanding the lesion. Immunohistochemistry is considered to be a hallmark in pathology for learning the molecular pathogenesis and giving a correct final diagnosis. Several markers have been used to investigate and understand this lesion, and a compilation of the findings has been tabulated

    Interventional Cardiology and Catheter-Based Interventions in Pregnancy

    No full text
    Cardiovascular disease is the leading cause of maternal mortality worldwide and has been increasing in prevalence over the last several decades. Pregnancy is associated with significant hemodynamic changes that can overwhelm the maternal cardiovascular reserve, and may exacerbate previously asymptomatic cardiovascular disease. Complications associated with these may cause substantial harm to both the mother and the fetus, and the management of these conditions is often challenging. Numerous novel treatments and interventions have demonstrated the safety and efficacy of managing these conditions outside of pregnancy. However, there are little data regarding their use in the pregnant population. In this review, we describe the common cardiovascular diseases encountered during pregnancy and discuss their management strategies, with a particular focus on the role of percutaneous, catheter-based therapeutic interventions

    Myopathy Associated With Statins and SGLT2 - A Review of Literature.

    No full text
    Drug-induced myopathy is a well-described clinical entity characterized by muscle damage leading to symptoms ranging from myalgias to rhabdomyolysis and acute kidney injury. Many pharmacotherapies are known to precipitate myopathic symptoms. Recent case reports suggest a potential relationship between the use of sodium/glucose cotransport 2 (SGLT2) inhibitors and onset of myopathy. The pathogenesis of this has yet to be elucidated. The relevance of this association is augmented by the recent popularity of SGLT2 inhibitors as well as the tendency for them to be prescribed alongside statins. This study reviewed the literature on the incidence and mechanism of drug-induced myopathy in patients with type 2 diabetes mellitus who are taking SGLT2 inhibitors with and without the use of statins

    Predictors of permanent pacemaker insertion after TAVR: A systematic review and updated meta-analysis

    OBJECTIVES: The aim of this analysis was to evaluate the predictors associated with increased risk of permanent pacemaker implantation (PPMI) following transcatheter aortic valve replacement (TAVR). BACKGROUND: While TAVR has evolved as the standard of care for patients with severe aortic stenosis, conduction abnormalities leading to the need for PPMI is one of the most common postprocedural complications. METHODS: A systematic literature search was performed to identify relevant trials from inception to May 2020. Summary effects were calculated using a DerSimonian and Laird random-effects model as odds ratio with 95% confidence intervals for all the clinical endpoints. RESULTS: Thirty-seven observational studies with 71 455 patients were identified. The incidence of PPMI following TAVR was 22%. Risk was greater in men and increased with age. Patients with diabetes mellitus, presence of right bundle branch block, baseline atrioventricular conduction block, and left anterior fascicular block were noted to be at higher risk. Other significant predictors include the presence of high calcium volume in the area below the left coronary cusp and noncoronary cusp, use of self-expandable valve over balloon-expandable valve, depth of implant, valve size/annulus size, predilatation balloon valvuloplasty, and postimplant balloon dilation. CONCLUSION: Fourteen factors were found to be associated with increased risk of PPMI after TAVR, suggesting early identification of high-risk populations and targeting modifiable risk factors may aid in reducing the need for this post TAVR PPMI

    Linkage, initiation and retention of children in the antiretroviral therapy cascade

    In 2012, there were an estimated 2 million children in need of antiretroviral therapy (ART) in the world, but ART is still reaching fewer than 3 in 10 children in need of treatment. [1, 7] As more HIV-infected children are identified early and universal treatment is initiated in children under 5 regardless of CD4, the success of pediatric HIV programs will depend on our ability to link children into care and treatment programs, and retain them in those services over time. In this review, we summarize key individual, institutional, and systems barriers to diagnosing children with HIV, linking them to care and treatment, and reducing loss to follow-up (LTFU). We also explore how linkage and retention can be optimally measured so as to maximize the impact of available pediatric HIV care and treatment services
