Kehamilan resiko tinggi memberikan dampak besar terhadap Angka Kematian Ibu (AKI), salah satunya adalah preeklampsia. Dampak yang dapat ditimbulkan dari preeklampsia pada ibu yaitu kelahiran prematur, oliguria, kematian, sedangkan dampak pada bayi yaitu pertumbuhan janin terhambat, oligohidramnion, dapat pula meningkatkan morbiditas dan mortalitas.Persalinan preterm menyebabkan kematian sampai 28% bayi baru lahir.Tujuan dari penelitian adalah untuk mengetahui hubungan preeklampsia dengan kejadian persalinan preterm.
Rancangan penelitian ini adalah korelasi dengan pendekatan retrospektif.Populasi penelitian ini adalah seluruh ibu bersalin sebanyak 291 responden.Teknik penelitian menggunakan teknik total sampling, dimana seluruh populasi dijadikan sampel.Variabel independen dalam penelitian ini adalah ibu bersalin dengan preeklampsia dan variabel dependent adalah persalinan preterm. Pengumpulan data menggunakan rekam medik pada bulan Maret tahun 2016, pengolahan data dengan menggunakan editing, coding, scoring, dan tabulating. Kemudian dianalisis dengan menggunakan uji statistik Chi kuadrat dengan taraf signifikan 0,05.
Hasil penelitian ini menunjukkan kejadian preeklampsia sebanyak 22 responden (7,6%) dan yang mengalami persalinan preterm sebanyak 27 responden (9,3%). Berdasarkan perhitungan dengan SPSS Versi 22 didapatkan p = 0,975 (p > 0,05). Dari hasil tersebut dapat disimpulkan bahwa H1 ditolak, yang artinya tidak ada hubungan antara preeklampsia dengan persalinan preterm.
Preeklampsia tidak selalu diiringi denganproses persalinan preterm. Petugas kesehatan, khususnya bidan sebagai ujung tombak pada pelayanan kesehatan ibu dan anak, harus dapat mendeteksi secara dini adanya komplikasi dalam kehamilan dengan cara melakukan pemeriksaan kehamilan secara rutin sehingga dapat mendeteksi secara dini adanya kasus gawat darurat,dan dapat berperan aktif dalam menurunkan angka kematian ibu dan bayi.
Hubungan Antara Tingkat Depresi pada Penderita Kanker Payudara Lanjut Lokal dengan Kadar Kortisol Serum Darah
Authors: Budijitno Selamat 
Published: September 2019

Latar belakang : Stress neurologis, melalui sitokin-sitokin internal di dalam sawar otak akan menyebabkan sekresi kortisol oleh kelenjar adrenal melalui HPA axis. Tujuan penelitian ini adalah membuktikan bahwa terdapat korelasi antara pengaruh depresi terhadap kadar kortisol pada penderita tumor payudara stadium III B. Metode : Penelitian ini merupakan penelitian klinis CrossSectional, yang dilakukan pada 40 pasien wanita penderita kanker payudara duktal invasif stadium lanjut lokal (stadium IIIA, IIIB, dan IIIC). Tingkat depresi diukur dengan quesioner standar Beck Depression Inventory (BDI). Kadar kortisol dihitung dengan metode ELISA, dan diambil dari serum sampel pada jam 09.0010.00. Hasil : Kadar kortisol rerata 254,98; SD 48,65 ng/ml, hasil BDI minimum 4, maksimal 9, dengan median 7. Berdasarkan hasil Spearman corellation terdapat hubungan bermakna antara nilai BDI dengan kadar kortisol (p<0,001, r=0,868). Simpulan : Sesuai dengan teori yang ada, kadar kortisol berhubungan erat dengan ekspresi kortisol. Proses sitokin-sitokin internal di otak pada pasien dengan IDC masih berlangsung sesuai teori, tetapi hal ini masih perlu diteliti lebih lanjut lagi. Pada penelitian ini juga terbukti quesioner BDI mempunyai korelasi yang kuat untuk pengukuran tingkat depresi yang dilihat dari parameter kortisol.

Published: September 2019

Pendahuluan : Proses pemberian air susu ibu (ASI) segera setelah bayi lahir, 30 menit hingga satu jam setelah bayi lahir disebut Inisiasi Menyusu Dini (IMD). Bayi dikatakan berhasil dalam melakukan IMD jika bayi dapat melekat dan dapat menyusu pada puting payudara ibu dalam 30 menit hingga satu jam pertama setelah lahir. Dan dikatakan gagal jika proses tersebut tidak dapat dilalui. Namun, tidak semua bayi dapat melalui proses ini.
Tujuan : Untuk menentukan faktor-faktor resiko yang mempengaruhi kegagalan inisiasi menyusu dini berdasarkan faktor maternal, neonatal dan persalinan.
Metode : penelitian case control, dilaksanakan di R.S. Dr. Kariadi, Semarang antara bulan Januari hingga Maret 2016.Faktor resiko yang diteliti adalah usia ibu saat melahirkan, keinginan untuk melakukan IMD, jumlah paritas, tingkat pendidikan ibu, dan usia gestasi sebagai faktor maternal, durasi persalinan kala II, warna cairan amnionsebagai faktor persalinan danÂ berat badan lahir, skor Apgar yang sebagai faktor neonatal. Data diambil dari rekam medis pasien dan berdasarkan wawancara dengan orang tua yang dilakukan di bangsal perinatologi R.S. Dr. Kariadi.
Hasil : Subyek penlitian terdiri dari 60 bayi yang terdiri dari 30 bayi yang berhasil melakukan IMD sebagai grup kontrol dan 30 bayi yang gagal dalam melakukan IMD sebagai grup kasus. Pada penelitian ini 18,3% subyekdengan durasi persalinan kala II > 1 jam dan 81,7% subyekdengan durasi persalinan kala II â‰¤1 hour. Faktor Maternal dan neonatal tidak bermakna secara statistik sebagai faktor resiko yang mempengaruhi kegagalan IMD, tetapi faktor persalnan terutama durasi persalinan kala II lebih dari 1 jam merupakan faktor resiko yang bermakna terhadap kegagalan IMD (OR=6; 95% CI 1,030â€“ 30,725, p=0,02).
Kesimpulan : Durasi persalinan kala II lebih dari 1 jam merupakan faktor resiko yang mempengaruhi kegagalan IMD.

Introduction: Enteropathogenic Escherichia coli is an important causative agent of diarrhea in both developed and developing countries.
Methodology: We assessed the antibiotic resistance profile and the ability of 71 Enteropathogenic Escherichia coli (EPEC) isolates from children in the age group 6 years, or younger, to form biofilm. These children were hospitalized in Cosme and Damião Children Hospital in Porto Velho, Western Brazilian Amazon, between 2010 and 2012, with clinical symptoms of acute gastroenteritis.
Results: The highest frequency of atypical EPEC (aEPEC) isolates reached 83.1% (59/71). Most EPEC isolates presented Localized Adherence Like (LAL) pattern in HEp-2 cells (57.7% - 41/71). Biofilm production was observed in 33.8% (24/71) of EPEC isolates, and it means statistically significant association with shf gene (p = 0.0254). The highest antimicrobial resistance rates and a large number of multiresistant isolates 67.6% (48/71), regarded cefuroxime (CXM), ampicillin (AMP), trimethoprim-sulfamethoxazole (SXT) and tetracycline (TET), respectively, mainly in typical EPEC (tEPEC). Furthermore, 96% (68/71) of EPEC isolates in the present study were resistant to at least one antibiotic, whereas only 3 isolates were sensitive to all the tested drugs.
Conclusion: Based on our findings, there was increased aEPEC identification. EPEC isolates showed high resistance rate; most strains showed multiresistance; thus, they work as warning about the continuous need of surveillance towards antimicrobial use. Besides, the ability of forming biofilm was evidenced by the EPEC isolates. This outcome is worrisome, since it is a natural resistance mechanism of bacteria.

Published: September 2019

Introduction: Klebsiella pneumoniae is an opportunistic pathogen accounting for 5-7% of hospital acquired infections. The emergence of carbapenem-resistant Klebsiella pneumoniae has been increasing rapidly over recent years causing many therapeutic problems worldwide. This study aimed to research the antimicrobial resistance profile, detect β-lactamase genes among clinical isolates of K. pneumoniae, and determine their clonal relatedness.
Methodology: All Klebsiella pneumoniae isolates were obtained from teaching hospitals in Urmia, Iran. Antimicrobial susceptibility testing was done by the disk diffusion method. Furthermore, minimum inhibitory concentrations of imipenem were determined by applying Etest strips. Screening of β-lactamase-producing isolates was performed by the combined disk method and modified Hodge test. The detection of β-lactamase genes was conducted by polymerase chain reaction (PCR), and isolates’ clonal relatedness was evaluated by random amplified polymorphic DNA (RAPD)-PCR.
Results: Overall, 45 out of 182 (24.7%) K. pneumoniae isolates were non-susceptible to imipenem. The combined disk method and modified Hodge test revealed that 93.3% and 71.1% of the imipenem non-susceptible isolates were β-lactamase producers, respectively. The presence of blaVIM, blaNDM, blaKPC, and blaIMP genes was confirmed in 48.9%, 15.6%, 11.1%, and 6.7% of the β-lactamase-producing isolates, respectively. RAPD-PCR revealed that 73% of these isolates were classified into six different clusters.
Conclusions: A relatively high prevalence of β-lactamase genes was seen among multidrug-resistant isolates of K. pneumoniae. Most patients infected with β-lactamase-producing isolates had a history of long-term hospitalization and nosocomial infections. The predominance of β-lactamase genes in intensive care unit and internal units alarm clinicians to the growth of hospitalization and mortality rates.

Published: September 2019

Le cancer colorectal (CCR) touche chaque année environ 43 000 personnes en France et est responsable de près 18 000 décès par an. Le Programme national de dépistage organisé contribue à sa détection précoce. La mise à disposition du kit se fait auprès du médecin traitant ou, à défaut, auprès du centre régional en charge de la personne invitée. Bien souvent, la démarche consistant à se rendre chez son médecin traitant pour récupérer le test n’est pas faite et la participation au dépistage organisé en pâtit. Notre projet vise à évaluer l’impact de la mise à disposition de ce test dans les pharmacies sur le dépistage du cancer colorectal en Corse. L’article décrit la méthode employée pour mobiliser les pharmaciens des officines du territoire et les fournir en kits de dépistage ainsi que le suivi des personnes qui ont participé au test. Les résultats présentés mettent en évidence un impact très positif de l’expérimentation, avec une progression du taux de réalisation à 36 % sur la période.

Leren exonereren: een aantal gezichtspunten ten aanzien van het contractueel reguleren van aansprakelijkheid
In deze bijdrage wordt de rol die exoneraties in b2b-verhoudingen spelen besproken en formuleert de auteur regels die bij het opstellen van een goede exoneratiebepaling van nut kunnen zijn. De auteur wijst op het belang van het juridisch (logistiek) kwalificeren van de overeenkomst, de vraag of de schadeplicht voortvloeit uit een temporeel of kwalitatief ten achter blijven en op de uitleg van exoneraties. Onderzocht wordt ook of toetsing van het beding aan de beperkende werking van de redelijkheid veel verschilt van de norm ‘onredelijk bezwarend’ uit artikel 6:233 sub a Burgerlijk Wetboek en de omstandigheden die in de rechtspraak een rol spelen bij de beantwoording van de vraag of een exoneratie terzijde moet worden gesteld.

Academic SEO – increasing the visibility of research output
Authors: Schilhan Lisa , Kaier Christian 
Published: September 2019

In times of an ever-increasing information overload, Academic Search Engine Optimization (ASEO) supports findability of relevant information and contributes to the FAIR principles. It enhances efficiency in literature and data search and therefore plays an increasing role in the research lifecycle.
ASEO is an important aspect to consider when preparing a scientific manuscript for publication. Authors can increase the visibility of their papers in library catalogues, databases, repositories and search engines with simple measures like choosing informative author keywords. The more (meta-)data these search algorithms can use, the higher the probability that a data set or paper will show up in a result list. ASEO enables search algorithms and readers to quickly and unambiguously identify relevant content, thus also helping institutions to increase research visibility. In addition, authors and publishers share an interest in describing content in a way that makes it easy to find it.
Librarians, with their extensive knowledge and wealth of experience in literature research and metadata management such as keyword assignment, can provide valuable advice on the role of as correct and complete metadata as possible and on suitable keywords for search algorithms. For this reason, the Publication Services at Graz University Library have recently started offering training and workshops for authors.
The presentation will provide an introduction into strategies to enhance visibility and findability of online content, such as research articles, with some theoretical background as well as practical examples.

AbstractLithium metal anodes with high energy density are important for further development of next‐generation batteries. However, inhomogeneous Li deposition and dendrite growth hinder their practical utilization. 3D current collectors are widely investigated to suppress dendrite growth, but they usually occupy a large volume and increase the weight of the system, hence decreasing the energy density. Additionally, the nonuniform distribution of Li ions results in low utilization of the porous structure. A lightweight, 3D Cu nanowire current collector with a phosphidation gradient is reported to balance the lithiophilicity with conductivity of the electrode. The phosphide gradient with good lithiophilicity and high ionic conductivity enables dense nucleation of Li and its steady deposition in the porous structure, realizing a high pore utilization. Specifically, the homogenous deposition of Li leads to the formation of an oriented texture on the electrode surface at high capacities. A high mass loading (≈44 wt%) of Li with a capacity of 3 mAh cm−2 and a high average Coulombic efficiency of 97.3% are achieved. A lifespan of 300 h in a symmetrical cell is obtained at 2 mA cm−2, implying great potential to stabilize lithium metal.
Advanced Multifunctional Field Effect Devices Using Common Gate for Both 2D Transition‐Metal Dichalcogenide and InGaZnO Channels

Published: September 2019

AbstractVarious functions are introduced from a unique field‐effect device structure which combines or merges transition metal dichalcogenide (TMD) and InGaZnO (IGZO) channels together on one common gate: multivalue field effect transistors (FETs), photodetecting devices, and signal frequency doublers. Judging by the individual transfer characteristics of two FET devices, the n‐IGZO FET always shows higher drain current and more positive‐side turn‐on voltage than those of n‐TMD channel FETs. As a result, a combined transfer characteristic presents two‐step drain current levels, so that their load‐resistance inverter might demonstrate three value output voltage signals. Those ternary value inverter devices with n‐IGZO/n‐ReSe2 or n‐IGZO/n‐WSe2 combination also operate as a photodetector, responding to visible/near infrared (IR) photons with a fast photodynamics of 30 ms rising/falling time. The most interesting is the ambipolar device achieved from n‐IGZO FET/p‐MoTe2 FET combination circuit. The ambipolar device circuit operates as an alternating current (AC) signal frequency doubler and demonstrates twofold organic light emitting diode blinking in one AC period. This unprecedented technique for the multifunctional field effect TMD devices incorporating n‐IGZO FETs will open a new path toward future electronics.
Contorted Polycyclic Aromatic Hydrocarbons with Two Embedded Azulene Units
Authors: Yang Xuan , Rominger Frank , Mastalerz Michael 
Published: September 2019

AbstractPolycyclic aromatic hydrocarbons (PAHs) that contain both five‐ and seven‐membered rings are rare, and those where these rings are annulated to each other and build azulene units have, to date, mainly been generated in minute amounts on surfaces. Herein, a rational approach to synthesize soluble contorted PAHs containing two embedded azulene units in the bulk is presented. By stepwise detachment of tert‐butyl groups, a series of three azulene embedded PAHs with different degrees of contortion has been made to study the impact of curvature on aromaticity and conjugation. Furthermore, the azulene PAHs showed high fluorescence quantum yields in the NIR regime.
Ultrafast Intercalation Enabled by Strong Solvent–Host Interactions: Understanding Solvent Effect at the Atomic Level

Published: September 2019

AbstractSolvents play an essential role in many areas of chemistry and is the cornerstone of understanding reactivity in solution‐phase reactions. Solvent effects have been widely observed in intercalation reactions; however, understanding of the influence of solvents on the thermodynamics and kinetics remains largely elusive in intercalation chemistry. Now, the solvent‐dependent kinetics of ferrocene intercalation into a layered vanadyl phosphate (VOPO4⋅2 H2O) host is presented, with a special focus on primary alcohols. From methanol to 1‐hexnaol, the intercalation rate peaks in 1‐propanol (80 times faster than the slowest case in methanol). Similar kinetics of exfoliation are also found in these solvents without ferrocene. The correlation between intercalation and exfoliation is understood at atomic level by DFT calculations, which reveal the role of pre‐intercalated solvent molecules play in intralayer interactions, interlayer expansion, and layer sliding.

Single‐track year‐round education for improving academic achievement in U.S. K‐12 schools: Results of a meta‐analysis
Authors: Fitzpatrick Dan , Burns Jason 
Published: September 2019

AbstractBackgroundResearch shows that over summer break, students forget approximately 1 month of learning in math and reading; furthermore, some studies find that low‐income students lose ground relative to peers. Year‐round education (YRE) redistributes schooldays to shorten summer. Prior analyses pooled single‐track YRE (academic intervention in which all students attend school on a common calendar) and multitrack YRE (fiscal intervention countering overcrowding, in which groups of students attend school on staggered schedules).Search MethodsSystematic search of 22 online databases in summer 2017 yielded 494 de‐duplicated results; 81 warranted full‐text examination. After applying selection criteria, nine studies met criteria but did not report data that allowed effect size calculation. Thirty studies constituted our analytic sample.Selection CriteriaStudies needed to be of K‐12 single‐track YRE (not multitrack, not a mix of single‐ and multitrack, and not a study that did not specify track), with no accompanying extended instructional time. Studies needed to be from 2001 to 2016, include outcome data, and include a comparison group.DataWe extracted 55 math g, 58 reading g, 29 math odds ratio, and 27 reading odds ratio effect sizes.ResultsStudents at single‐track YRE schools show modestly higher achievement in both math and reading—by a magnitude similar to estimates of summer learning loss—but comparable proficiency. Unexpectedly, the effect was no greater for historically disadvantaged students. Math effects may be larger in middle than elementary school, but the reason is unclear. Importantly, studies of schools that shortened summer to the fewest weeks showed the largest effects in both subjects.
