Published: October 2020

A infecção odontogênica é um grave problema de saúde pública. O atendimento hospitalar fica basicamente direcionado a atenção aos casos mais graves que requerem tratamento imediato de antibioticoterapia endovenosa bem como remoção urgente da causa. Sendo assim, o objetivo é apresentar um caso de paciente de 43 anos de idade, sexo feminino, queixando-se de dor em região de dente 24 com aumento volumétrico evidente assim como drenagem espontânea de exsudato via sulco gengival. O tratamento após exames complementares de rotina foi a exodontia do elemento dentário sob anestesia local em atenção hospitalar associado a drenagem da coleção purulenta. Após eliminação da causa bem como a drenagem, 48 horas destas a paciente recebeu alta hospitalar com retorno programado. Segue sem queixas e sem outras afecções semelhantes.Descritores: Abscesso Periapical; Cirurgia; Terapêutica.ReferênciasMardini S, Gohel A. Imaging of Odontogenic Infections.

Sanitation dynamics: toilet acquisition and its economic and social implications in rural and urban contexts
Authors: Augsburg Britta , Rodríguez-Lesmes Paul 
Published: October 2020

Abstract
This paper uses primary micro-data from Indian households residing in rural villages and poor urban neighbourhoods to shed light on household sanitation decision-making. We use a theoretical economic model to reduce the dimensionality and complexity of this process. Beyond the most commonly analysed motivator, health, we consider economic and non-pecuniary benefits. We provide empirical evidence that each of these margins matter, and do so in both rural and urban contexts, and discuss how our findings can be explored in sanitation policy and programme design.
Modular treatment of arsenic-laden brackish groundwater using solar-powered subsurface arsenic removal (SAR) and membrane capacitive deionization (MCDI) in Vietnam
Authors: Hellriegel U. , Cañas Kurz E. E. , Luong T. V. , Bundschuh J. , Hoinkis J. 
Published: October 2020

Abstract
To evaluate energy efficient concepts for the modular treatment of brackish water, pilot trials for groundwater desalination and arsenic (As) removal were carried out in the Mekong Delta, Vietnam. Groundwater here is affected by naturally occurring high iron (Fe2+) and As concentrations, while, in coastal regions, groundwater is additionally contaminated by high salinity mostly due to seawater intrusion. Desalination was conducted by membrane capacitive deionization (MCDI), which shows low specific energy consumption (SEC). Anoxic groundwater with As(III) and Fe2+ was treated using a pre-oxidation step called subsurface arsenic removal (SAR) with the main advantage that no As-laden waste is produced. The pilot plant was operated using a photovoltaic system (3 kWp) and a small wind turbine (2 kWp). The SEC of drinking water produced was 3.97 kWh/m3. Total dissolved solids (TDS) of 1,560 mg/L were lowered to 188 mg/L, while Fe2+ was reduced from 1.8 mg/L to the below detection limit and As from 2.3 to 0.18 μg/L. The results show that SAR is a feasible remediation technique for Fe2+ and As removal in remote areas, and demonstrate the potential of MCDI for brackish water desalination coupled with renewable energies. However, improvements in energy demand of the MCDI module can still be achieved.

Abstract
This study aimed to find biosurfactant producing and crude oil-degrading bacteria able to decontaminate crude oil from wastewater. The bacteria that were isolated from contaminated sites in an oil refinery plant in Isfahan, Iran, were identified by 16S rDNA sequencing as Achromobacter kerstersii strain LMG3441, Klebsiella pneumonia strain SKBA6, and Klebsiella variicola strain SKV2. According to the results obtained from different tests for the production of biosurfactant among three strains, only Achromobacter kerstersii strain LMG3441 was selected for further study. The pattern of residual hydrocarbons was analyzed by high-resolution gas chromatography-mass spectrometry (GC-MS). This novel and indigenous strain was capable of producing the highest amount of a glycolipid biosurfactant (7.81 g/L) in MSM (mineral salt medium) with 1% (v/v) crude oil as the only source of carbon and energy. The compound showed high surface activation capacity with reduction of surface tension from 40 mN m–1 in the control to 23.3 mN m–1 by the bacterium. The results of GC-MS for assessment of residual hydrocarbons in the MSM and comparison with crude oil as a control showed that 53% of the hydrocarbons in the crude oil were consumed by this novel strain.
Optimization of methylene blue degradation by Aspergillus terreus YESM 3 using response surface methodology
Authors: Mohammed Youssef M. M. , Mabrouk Mona E. M. 
Published: October 2020

Abstract
Synthetic dyes released from many industries cause pollution problems in aquatic environments affecting public health. The present study aimed to explore the potentiality of Aspergillus terreus YESM 3 (accession number LM653117) for colour removal of three different dyes: methylene blue (MB), malachite green (MG) and safranin (S). Results showed that the tolerance index of the studied fungus against tested dyes decreased in the order: methylene blue, safranin and malachite green. Removal of methylene blue colour was improved by using Box–Behnken design. Optimum condition for methylene blue biodegradation in Czapek Dox broth was achieved at pH 6, of 31.41 mg/L dye concentration and an inoculum of 5.7778 × 104 (conidia/mL) with biodegradation of 89.41%. Thus, a novel and eco-friendly system for the biodegradation of dyes using Box–Behnken design has been efficiently developed. Accordingly, A. terreus YESM 3 can be professionally used for bioremediation of methylene blue dye in wastewater and removal of environmental pollution.

Published: October 2020

Background:
Recruitment of gene modifying bone marrow mesenchymal stem cells
(BMSCs) has been considered an alternative to single-cell injection in articular cartilage repair.

Purpose:
This study aimed to investigate whether the effect of runt-related transcription factor
2(Runx2) overexpression bone marrow mesenchymal stem cells in vivo could improve the quality
of repaired tissue of a knee cartilage defect in a rabbit model.

Methods:
Thirty-two New Zealand rabbits were randomly divided into four groups. The blank
group (Con) did not receive anything, the model group (Mo) was administered saline, the simple
stem cell group (MSCs) received MSCs injection, and the Runx2 transfection group (R-MSCs) received
Runx2 overexpression MSCs injection. After adapting to the environment for a week, a 5
mm diameter cylindrical osteochondral defect was created in the center of the medial femoral
condyle. Cell and saline injections were performed in the first and third weeks after surgery. The
cartilage repair was evaluated by macroscopically and microscopically at 4 and 8 weeks.

Results:
Macroscopically, defects were filled and surfaces were smoother in the MSCs groups than
in the Mo group at 4th week. Microscopically, the R-MSCs group showed coloration similar to surrounding
normal articular cartilage tissue at 8 weeks in masson trichrome staining. The COL-II,
SOX9, and Aggrecan mRNA expressions of MSCs were enhanced at 4 weeks compared with R-MSCs,
then the expression reduced at 8 weeks, but was still higher than Mo group level (P<0.05).
The western blot examination revealed that the COL-IIand SOX9 expression of MSCs was higher
than R-MSCs at 4 weeks, then the expression reduced at 8 weeks, but was still higher than the Mo
level (P<0.05). The IL-1β content in the joint fluid also revealed that cartilage repair with R-MSCs
was better than that with MSCs at 8 weeks (P<0.05).

Conclusions:
The R-MSCs group showed cellular morphology and arrangement similar to surrounding
normal articular cartilage tissue, and Runx2 overexpression of MSCs resulted in overall superior
cartilage repair as compared with MSCs at 8 weeks.

Authors: Patel Nalin G. , Patel Dhruvkumar M. , Patel Mukundkumar V. , Patel Maitri M. , Patel Tanmay R. , Patel Suyog Y. 
Published: October 2020

Background:
High-frequency ultrasound (HFUS) is a mobile, radiation-free imaging
tool for the diagnosis of musculoskeletal disorders. We aim to demonstrate the diagnostic value of
dynamic HFUS for undiagnosed lower chest, upper abdomen, and loin pain with this case series.

Case Series:
A cricketer presented with long-standing left-sided dull ache lower chest and upper abdominal
pain, aggravated on exertion and leaning forward. His previous laboratory and previous
imaging tests were unrevealing. Dynamic HFUS of his left ribs during hooking maneuver demonstrated
slipping of the eighth rib over the seventh rib associated with clicking. He also reported tenderness
over this region. He was diagnosed with slipping rib syndrome (SRS), and was treated with
the eighth nerve block under the HFUS guidance. The second and third cases presented with chronic
undiagnosed waxing and waning loin pain despite extensive laboratory and radiological workup.
Both patients demonstrated twelfth rib HFUS probe tenderness in a sitting position with a specific
movement that reproduced the pain during the dynamic HFUS study. The diagnosis of twelfth rib
syndrome (TRS) was confirmed and treated successfully with a local intercostal nerve block.

Review of the Literature:
HFUS is the most underutilized imaging tool for the diagnosis of unexplained
upper abdominal and lower chest pain syndromes. We identified only a few such reported
cases managed with the help of HFUS.

Conclusion:
The dynamic HFUS is a valuable imaging modality for the undiagnosed lower chest,
upper abdominal, or loin pain.

La otredad en la extimidad
Authors: Odetti Verónica Beatriz 
Published: October 2020

El presente artículo busca destejer las nuevas configuraciones de la subjetividad en el contexto de la extimidad (Sibilia, 2008), es decir, pensar reflexivamente estos nuevos modos de ser y estar en las redes, poniendo especial atención a la configuración de las subjetividades desde la alteridad. Para tal fin se tensionan las propuestas teóricas de Lévinas, Maturana y Sibilia. Emerge entonces una nueva gestión del yo en sus coordenadas espaciales y temporales signadas por la virtualidad y las redes sociales, donde el rostro (Lévinas, 1987) y la legitimidad del otro (Maturana, 1997) adquieren presencia en un like o emojis o stikers. No hay rostro ni emociones que permitan configurar la alteridad, aparecen caricaturas que remedan emociones y que buscan suplir ese lugar del otro en la configuración de las subjetividades instantáneas, instagrameables y fugaces que se nos presentan.
PENGARUH PENYETELAN HYPERPARAMETER TERHADAP KINERJA PREDIKSI RANDOM FOREST PADA PENDETEKSIAN SPAM
Authors: SALMAN NUR , SARI MUSTIKA 
Published: October 2020

Random Forest memiliki versi modifikasi dan sejumlah hyperparameter yang terpasang “default” pada aplikasi. Penelitian terdahulu telah membahas bahwa penyetelan hyperparameter dapat berpengaruh terhadap kinerja sistem. Namun, penyetelan hyperparameter secara manual bukan pekerjaan yang sederhana untuk sebuah algoritma yang kompleks. Mempertimbangkan bahwa banyak dataset keamanan data yang berdimensi tinggi, maka otomatisasi dan efisiensi menjadi pertimbangan dalam pekerjaan ini. Penyetelan hyperparameter bertujuan membentuk kombinasi hyperparameter yang dapat meningkatkan kinerja prediksi. Penelitian ini memuat perbandingan kinerja evaluasi hasil prediksi dengan penyetelan hyperparameter. Hasil yang diperoleh pada pendeteksian spam dengan 3-fold dan 5-fold-cross-validation, variabel menunjukkan bahwa kinerja prediksi meningkat menjadi 95% dan 95.4% pada Accuracy dan mencapai 98.5% dan 98.7% pada AUC, sementara ukuran tingkat kesalahan menurun hingga .50 dan .46 untuk MMCE dan .75 dan .80 untuk Brier Score.Kata Kunci — penyetelan, hyperparameter, kinerja, prediksi.
