Correlation of Ferritine and Brain Derived Neurotrophic Factor (BDNF) Levels in Preeclampsia
Authors: Putri Dona Mirsa , Ariadi Ariadi , Yusrawati Yusrawati
Published: July 2021

Iron deficiency anemia that followed by low serum ferritin levels in early pregnancy has an indirect impact on decreasing the expression of Brain Derived Neurotrophic Factor (BDNF) in the maternal hippocampus. BDNF together with its receptor tyrosine kinase B (TrkB) induced the expression of metalloproteinase-9 (MMP-9) which plays an important role in blastocyst implantation, trophoblast invasion and placental development. Decreasing BDNF levels can interfere with those process which caused imbalance of pro-angiogenic and anti-angiogenic factors such as VEGF, PIGF, sFlt1 and sEng that leads to preeclampsia. This study aims to determine the correlation between ferritin and BDNF serum levels in preeclampsia.Keywords: Preeclampsia, ferritin, iron deficiency anemia, Brain Derived Neurotrophic Factor
Differences of Increased Bishop Scores Between Neutrophil Swab Vaginal â‰¤ 5 and > 5 in 41 Weeks of Pregnancy Induced With Misoprostol
Authors: Hartanto Boby , Serudji Joserizal , Defrin Defrin
Published: July 2021

The incidence of labor induction with various indications was to increase. The key to successful labor induction is a ripe cervix. Research shows that the degree of cervical rippening as assessed by the Bishop score is influenced by the level of neutrophils contained in the cervical stroma which can be detected by performing a vaginal swab. Neutrophils will produce collagenase in the form of matrix metalloproteinase - 8 (MMPs - 8) which will degrade cervical collagen fibers, so that the cervix becomes soft and ripe. Misoprostol is the drug most widely used in labor induction today. Purpose: This study was to determine the difference in Bishop score increase between vaginal swab neutrophils â‰¤ 5 and > 5 in pregnancy â‰¥ 41 weeks induced by misoprostol.Keywords: Bishop score, neutrophil, vaginal swab, misoprostol

Angiosarcoma Clinically Mimicking a Targetoid Hemosiderotic Hemangioma
Authors: Nam Hannah , Lim Jordan , Flamm Alexandra
Published: July 2021

Angiosarcoma is a rare malignant entity that typically presents as a rapidly progressing ecchymotic or cellulitis-like lesion with subsequent bleeding or ulceration. Atypical presentations have been described, such as cases mimicking rosacea, making the diagnosis more challenging.  Due to the high rate of local recurrence, metastasis, and disease-specific mortality, early identification and treatment is critical. Here we describe a 69-year-old man with a vascular targetoid lesion clinically consistent with a targetoid hemosiderotic hemangioma (THH); however, biopsy was consistent with an angiosarcoma. Early diagnosis of this lesion resulted in prompt wide local excision and no detection of metastasis. This case report highlights the importance of thorough evaluation of new onset vascular lesions and the unique THH-like presentation of an angiosarcoma.

Authors: Tassavor Michael , Hashim Peter , Babalola Folawiyo , Bhatt Mehul
Published: July 2021

To the Editor: Cutaneous warts are seen in as many as a quarter of immunosuppressed patients. 1 Cell-mediated immunodeficiency, as seen in HIV, is correlated with increased rates of palmoplantar warts. 2 These warts often cause discomfort, and can progress to verrucous carcinoma. As they can be resistant to traditional treatments like cryotherapy, patients must resort to more aggressive and invasive measures like intralesional bleomycin. In this case report, we present an immunocompromised patient with HIV successfully treated for his palmoplantar human papilloma virus (HPV) warts using the nonavalent HPV vaccine (Gardasil 9TM, Merck Inc, Kenilworth, NJ, USA) after only marginal improvement with six treatments of bleomycin.

Published: July 2021

Objective: This study was a budget impact analysis based on a budget impact model (BIM) and formularies from different commercial payer types (excluding Medicare and Medicaid). The primary objective of this study was to determine the potential cost savings utilizing precision medicine testing of biologics in patients with psoriasis. The evaluation projects the predicted cost savings of multiple formulary scenarios, simulated through the BIM.
Methods: A budget impact model was constructed to simulate the impact of Mind.Px, a transcriptomic predictive precision medicine test that can discriminate between psoriasis responders and non-responders, on psoriasis drug usage. This model simulated the impact of Mind.Px on different formularies and cost scenarios, considering the efficacy of individual biologics. All formularies used were acquired from the Policy Reporter database.
Results: Several payers representing a spectrum of covered lives populations were used to simulate the impact of Mind.Px through the budget impact model. The budget impact model returned cost savings as low as $5,138 annually to as high as $13,141 annually. Based on the analysis of this subset of payers, the model yielded average cost savings of $8,492 annually as well as an average wasted spend savings of $16,567. All Savings are represented on an annual per patient basis.
Conclusions: These savings demonstrate the potential cost savings that precision medicine testing can provide to ease the economic burden on payers, clinics/hospital systems, and patients, and may fill the need for a better method to prescribe drugs for the treatment of psoriasis.

Authors: Carlos Carmen , Brown Christen , Elliott Erika , Murina Andrea
Published: July 2021

Introduction: Participation in research has become increasingly popular amongst US medical students hoping to match into dermatology residency. While medical students have increasingly high research output by the time of graduation, the preparedness of medical students for independent research is unknown.
Methods: An anonymous survey was distributed to 137 dermatology interest groups across the country. The survey contained 21 multiple choice and free text questions that assessed students’ research experiences and self-assessed competency in key research components. Fifty-seven students participated.
Results: Students were most comfortable with creating posters for presenting research, writing an abstract and reviewing charts to gather pertinent data for research projects. Students reported a below-average comfort level with data analysis. Medical students who participated in more than eight research experiences and those who perform epidemiological research or commentaries have greater confidence in their ability to conduct research. 
Conclusion: Experience in research is associated with the ability to conduct research independently, but there is significant variance in the comfortability to perform essential research-related tasks.

Authors: Clark Kayla , Miori Virginia , Alvarado Jones Virgina , Tsoukas Maria
Published: July 2021

Background:
The COVID-19 pandemic caused substantial disruptions to medical education. We hypothesized that these disruptions may affect students applying to competitive residencies such as dermatology.
Methods:
A 24-question IRB-exempt, online, anonymous survey was distributed to 240 eligible medical students via social media to assess dermatology residency applicants’ concerns due to the COVID-19 pandemic and to collect student-proposed solutions to assist with the virtual application cycle. Eligibility consisted of US MD students applying to dermatology residency in the 2020-2021 or 2021-2022 application cycles. Statistical significance was calculated using the Chi-squared procedure, T-test/ANOVA, Mann Whitney test, and Kruskil Wallis tests with post-hoc Tukey and Mann Whitney tests.
Results:
Of 240 eligible students, 77 students attempted the survey whereas 69 students completed it (response rate 32%, completion rate 89%). Salient findings include students without home dermatology departments (WHD; n=24) who demonstrated concerns about research project changes (p=0.00). Students under-represented in medicine (UIM; n=34) concerned about lack of in-person interviews (p=0.00; p=0.04). MS3 (n=14), concerned about test cost (p=0.00), and effect on test scores because of COVID-19 (p=0.03). WHD and UIM applicants showed concerns about changes in clinical experiences (p=0.03, p= 0.03, respectively). Lastly, WHD, UIM and MS3 expressed concerns about obtaining quality recommendation letters (p=0.00, p=0.04, and p=0.03, respectively).
Conclusion:
Our findings demonstrate the various concerns shared by dermatology residency applicants because of the COVID-19 pandemic. The suggested solutions offered by participants in our study can be used to improve processes for candidates in the 2021-2022 residency application cycle.

Cutis marmorata telangiectatica congenita (CMTC) is an uncommon, congenital, cutaneous vascular disease with an unknown pathogenesis. Although considered as a benign condition, anomalies such as body asymmetry are frequently associated. Herein we present a series of patient with diagnosis of CMTC with a focus on clinical outcomes. In our series, limb length abnormalities were the most common associate anomaly, occurring in 24% of the subjects, similar to other series with rates of 33% and 27% but higher than the general population (6.7%). Importantly, dermatologist should be aware of the frequently associated anomalies in CMTC, such as leg length discrepancy, which may have serious consequences if not recognized and treated.
Utility of targeted balloon protection of the venous sinus for endovascular treatment of dural arteriovenous fistula by transarterial embolization with Onyx: A case report and literature review
Authors: Tagawa Masahiko , Inoue Akihiro , Murayama Kentaro , Matsumoto Shirabe , Ozaki Saya , Nishikawa Masahiro , Shigekawa Seiji , Watanabe Hideaki , Kunieda Takeharu
Published: July 2021

Background:

Onyx has already been reported as an effective and safe agent in transarterial embolization of cranial dural arteriovenous fistula (d-AVF). However, successful treatment is related to not only complete shunt obliteration but also preservation of a normal route of venous drainage. Here, we present a case of transverse sigmoid d-AVF in which successful treatment was achieved by transarterial Onyx embolization with targeted balloon protection of the venous drainage.

Case Description:

A 70-year-old man presented with a 3-month history of tinnitus in the left ear and mild headache. Magnetic resonance imaging (MRI) showed a cluster of abnormal blood vessels in the area of the left transverse sinus (TS)-sigmoid sinus (SS) junction. Cerebral angiography demonstrated a Cognard type IIa d-AVF at the left TS-SS junction, supplied mainly by vessels such as the left middle meningeal artery, left occipital artery, and left meningohypophyseal trunk. In the venous phase, the ipsilateral TS-SS was recognized as a functional sinus and the left vein of Labbe drained into the TS near the drainage channel. Based on these findings, we decided to perform endovascular treatment under a transarterial approach with Onyx using targeted balloon protection of the venous sinus to protect against Onyx migration and preserve antegrade sinus flow. The patient recovered well without sequelae, and follow-up MRI 12 months later showed complete disappearance of the d-AVF.

Conclusion:

This treatment strategy using targeted balloon protection may be very useful to preserve antegrade sinus flow in patients with Cognard type IIa d-AVF.

Objective: To perform a comparative analysis of MRI data obtained in the early postoperative period after repeated lumbar microdiscectomies in patients with and without epidural injection of “Nubiplant” polyacrylamide hydrogel (HG).
Material and methods: The MRI data of the lumbar spine in the early postoperative period after repeated removal of herniated disc (on the 3-15th day) in 84 (100%) patients were analyzed: 30 (35,7%) patients were injected intraoperatively epidurally with “Nubiplant” HG to prevent epidural fibrosis (main group (MG) and in 54 (64,3%) patients the HG was not injected (control group (CG).
Results: Comparative analysis of MRI data on the 3-15th day after surgery showed that the frequency of epidural edema and hemorrhage signs within the postoperative area in the MG was significantly lower as compared to the CG (p = 0,0444 and p = 0,0288 respectively).
To assess the accuracy of the epidural administration of an artificial biopolymer Nubiplant during lumbar microdiscectomy, in the early postoperative period the following MRI criteria could be helpful: i) absence of the dural sac deformation and dislocations of the spinal root; ii) well-defined margin of the adjacent spinal root; iii) homogeneous MRI signals of the Nubiplant zone; iv) absence of Nubiplant areas outside the postoperative area; v) sufficient sectoral coverage of the adjacent root with epidurally administered Nubiplant (optimally >1800). Nubiplant” HG in the patients of the MG was evaluated, and MRI criteria for assessing the correctness of its introduction were proposed.
Conclusions: In the early period after repeated lumbar microdiscectomies (on the 3-15th day), intraoperative epidural injection of “Nubiplant” HG was accompanied by a significant decrease of epidural edema and hemorrhage signs within the postoperative area. The proposed criteria of correctness of HG “Nubiplant” introduction allow unifying the approaches in radiological assessment of this patients.

Published: July 2021

Las habilidades blandas han ido tomando gran relevancia en el ámbito académico y laboral, debido a que estas se relacionan con mayores posibilidades de empleabilidad y éxito profesional. El presente artículo es una revisión documental de tipo panorámica sobre dichas habilidades en diferentes contextos, cuyo objetivo es identificar las principales investigaciones y sus abordajes en torno al campo educativo, sobre todo en el contexto universitario, y el laboral. Para ello se revisaron y analizaron treinta estudios sobre el tema, a partir de los cuales se encontraron algunas tendencias, como, por ejemplo, que la mayoría de ellos estaban escritos en idioma inglés; que en los años 2009 y 2012 fue donde más se publicaron documentos sobre el tema; que la metodología más utilizada fue la cuantitativa; que existen diversas denominaciones para este tipo de habilidades, entre otras tendencias. Frente a las posibles limitaciones, se encontró que el abordaje en Latinoamérica sobre estas habilidades ha sido escaso, así como las publicaciones en español; sin embargo, en la última década se ha despertado un fuerte interés por el tema, por ello se espera que aumente el número de investigaciones y publicaciones al respecto. Se concluye que es necesario fortalecer la instrucción en competencia blandas en el contexto universitario, puesto que estas complementan las competencias duras, lo que permite una formación integral de los estudiantes y mayores probabilidades de ingresar y mantenerse en el mundo laboral, dado que son también una necesidad en estos contextos organizacionales.

Published: July 2021

The challenges of online learning, created by the COVID-19 pandemic, have prompted a significant demand in researching this particular field of education. The adaptation to online learning, unfortunately, was applied in a context of unprepared teachers and students. This situation was caused by the new format of education, which differs significantly from massive open online courses, traditional learning or distance learning. The new hybrid model of education, prompted by the pandemic, has certainly become a trend that could incite future transformations in terms of teaching and learning. To better understand the specifics of this type of online learning, we asked the students (N = 705) from the University POLITEHNICA of Bucharest to express their opinion on their learning experience during the pandemic. The survey included the problems and expectations of the interviewees, and the research results were analyzed in the article. Our goal was to improve educational practices in the virtual educational environment. In this regard, we analyzed the important components of online learning, focusing on the following ones: the quality of the educational resources used to support the content, the improvement of the quality of the teacher- student relationships, time management, online assessment. The article also provides solutions for effective online learning, from the students’ perspective.

Published: July 2021

ABSTRAKPenelitian dengan topik robot hexapod telah banyak dikembangkan, namun sampai saat ini masih sedikit yang mengulas tentang kontrol keseimbangannya. Permasalahan yang kerap muncul adalah ketika robot berada dalam bidang miring, robot dapat terjatuh jika robot tidak dapat menyeimbangkan badan. Begitu pula dengan robot hexapod EILERO yang telah kami bangun. Untuk mengatasi permasalahan itu, selain pemodelan kinematik dan kinematika terbalik yang tepat, juga diperlukan suatu sistem keseimbangan yang baik. Dalam penelitian ini, kami menggunakan fuzzy logic untuk mengontrol keseimbangan robot EILERO dengan umpan balik data kemiringan dari sebuah sensor IMU. Setelah melalui beberapa pengujian yang komprehensif, didapatkan hasil bahwa robot dapat menyeimbangkan diri pada kondisi kemiringan papan pijakan antara -15° dan 15° pada orientasi kemiringan roll dan pitch. Robot mampu merespon dengan capaian steady state di bawah 3000 ms. Dengan demikian, robot EILERO semakin stabil dalam melintasi bidang yang tidak datar.Kata kunci: hexapod, EILERO, kinematika terbalik, fuzzy logic ABSTRACTResearch on the topic of the hexapod robot has been developed a lot, but until now there is little that has been discussed about balance control. The problem that often arises is that when the robot is on an inclined plane, the robot can fall if the robot cannot balance its body. Likewise with the EILERO hexapod robot that we have built. To solve this problem, besides proper kinematic modeling and inverse kinematic modeling, a good balance system is also needed. In this study, we used fuzzy logic to control the balance of the EILERO robot, with tilt data feedback from an IMU sensor. After going through several comprehensive tests, the results show that the robot can balance itself on the slope of the stepboards between -15 ° and 15 ° in the orientation of roll and pitch tilt. The robot is able to respond with steady state achievements below 3000 ms. Thus, the EILERO robot is increasingly stable in traversing uneven planes.Keywords: hexapod, EILERO, inverse kinematic, fuzzy logic

Pengaturan motor induksi pompa air biasanya menggunakan saklar tekanandengan histerisis. Kekurangan dari transduser ini adalah lebar histerisis yangterbatas dan penggunaan saklar mekanik untuk pengaturannya sehingga cepat ausdan berisik. Untuk mengatasinya dengan mengganti saklar mekanik dengan saklarelektrik triac dan penggunaan sistem mikrokontroler untuk mengatur waktu on/offtriac dan memanipulasi karakteristik saklar mekanik. Sistem terdiri dari saklarelektrik triac yang dikontrol sistem mikrokontroler dengan penyalaan sudut phasa.Besarnya sudut penyalaan ditentukan berdasarkan waktu on/off saklar tekananyang ditentukan oleh debit air yang keluar. Dengan mengatur sudut penyalaan,waktu histerisis on/off dapat diatur untuk debit air yang berbeda. Sistem KendaliOn/Off dapat digunakan untuk memanipulasi dan mengubah karakteristik saklartekanan dari 0.75s – 12s menjadi 6.2s – 10.1s untuk debit air 2 – 11 LPM danwaktu rata-rata on, ton_off = 7.4s dibanding ton_kon = 2.94s, sehingga sistempompa air kurang berisik suaranya

Implementation of Indonesian Education in the New Normal Era after the global Covid-19 pandemic uses an online learning system in accordance with new policies and regulations from the government to break the chain of virus spread in the community. With this system, teachers and students are required to understand online learning media quickly. However, students feel bored with the online learning system because it tends to be monotonous and many tasks are given. In addition, teachers are not necessarily proficient in using these online learning facilities and media, especially to make online learning interesting so that students do not get bored. Therefore, a webinar was conducted to improve teacher’s understanding of interesting online learning media such as Kahoot, Mentimeter, and Quizizz. Based on the results of quantitative calculations through the participant’s pre and post-tests, the participant’s knowledge changes were 28% on Mentimeter, 23% on Kahoot, and 18% on Quizizz.

Security is always an issue both in individuals and communal attentions. Any forms of threats and crimes that occur in the village area of Karyawangi Parongpong, such as motor vehicle theft, violence, drug abuse, gambling, and others are caused by a lack of supervision from local authorities. The limitation of surveillance distance is one of the problems. Thus, an effective and appropriate security system in a place is indispensable. In this paper, the design of the security system using IoT modules and ESP32 Camera, will be elaborated for karyawangi Parongpong's village. The system secures a village environment by detecting an intruder on the road, triggering Passive Infra Red (PIR) sensor, capturing all activities with ESP32 camera, and then sending data to a smart mobile phone through with Telegram application. These service activities were aimed at the improvement of security systems and increase knowledge of technology advances for rural communities in the Karyawangi Village environment, especially in security systems based on IoT.
Resource abundance and distribution drive bee visitation within developing tropical urban landscapes
Authors: Wojcik Victoria
Published: July 2021

Urban landscapes include a mix of biotic and anthropogenic elements that can interact with and influence species occurrence and behaviour. In order to outline the drivers of bee (Hymenoptera: Apoidea) occurrence in tropical urban landscapes, foraging patterns and community characteristics were examined at a common and broadly attractive food resource, Tecoma stans (Bignoniaceae). Bee visitation was monitored at 120 individual resources in three cities from June 2007 to March 2009. Resource characteristics, spatial distribution, and other local and regional landscape variables were assessed and then used to develop descriptive regression models of forager visitation. The results indicated that increased bee abundance and taxon richness consistently correlated with increased floral abundance. Resource distribution was also influential, with more spatially aggregated resources receiving more foragers. Individual bee guilds had differential responses to the variables tested, but the significant impact of increased floral abundance was generally conserved. Smaller bodied bee species responded to floral abundance, resource structure, and proximity to natural habitats, suggesting that size-related dispersal abilities structure occurrence patterns in this guild. Larger bees favoured spatially aggregated resources in addition to increased floral abundance, suggesting an optimization of foraging energetics. The impact of the urban matrix was minimal and was only seen in generalist feeders (African honey bees). The strongly resource-driven foraging dynamics described in this study can be used to inform conservation and management practices in urban landscapes. download Appendix
