Published: March 2021

El mielomeningocele es la malformación congénita más grave de la columna vertebral. La mayoría de los pacientes con secuelas de mielomeningocele en el Centro de Rehabilitación Infantil Teletón Aguascalientes (CRIT), tienen pobre o nula actividad física, secundaria al tipo de lesión y discapacidad, lo cual puede influir en el incremento del sobrepeso y la obesidad. Para conocer la prevalencia de obesidad y/o sobrepeso en el grupo de pacientes con mielomeningocele, se estudiaron 91 pacientes que acudieron a la Clínica de lesión medular del CRIT Aguascalientes. Encontramos que el 38.5% de la población fue diagnosticada con algún grado de obesidad, 15.3% tuvo sobrepeso, el 9.9% presento desnutrición leve y el 36.3% presentó peso normal. La localización de la lesión fue en 36.3% en la región lumbar, en 17.6% dorsal y lesión sacra en 9.9% de los casos. Se encontró obesidad mórbida en el 8.8% de los pacientes todos los cuales tuvieron lesión en la región lumbar. La orientación nutricional forma parte de un tratamiento integral que debe imperativamente promover en toda la familia buenos hábitos alimenticios, ya que es finalmente en el hogar donde el paciente logrará los objetivos nutricionales propuestos.

La rehabilitación del segmento anterior de la cavidad oral exige gran estética, por lo que debe ser realizado con toda precisión para otorgar excelentes resultados del tratamiento. Por razones estéticas en la actualidad se han utilizando restauraciones cerámicas libres de metal, principalmente en casos en donde el segmento anterior exige mayor similitud a los dientes adyacentes. En muchos pacientes esta zona presenta una gran variedad cromática. Se pueden localizar muñones pigmentados o supraestructuras de metal entre otros. Los dientes tratados endodónticamente requieren especial atención para su restauración, debido a la mayor posibilidad de fractura por la eliminación de estructura dental. En este trabajo se presenta un caso clínico de un paciente que requirió rehabilitación del segmento anterior de la cavidad oral mediante coronas de Disilicato de Litio y se discuten sus ventajas y desventajas.

El consumo de tabaco es un factor de riesgo en las principales causas de defunción en el mundo, especialmente enfermedades isquémicas, cerebro vasculares, crónicas de vías respiratorias y tumores malignos. Las tendencias muestran aumento de tasas de prevalencia de tabaquismo en adolescentes y jóvenes. Objetivo: Determinar prevalencia del consumo de tabaco en estudiantes de bachillerato. Material y Métodos: Estudio descriptivo observacional transversal prospectivo. Se aplicó la Escala Exploratoria de Consumo de Tabaco (EECT), autoadministrado, que evalúa prevalencia de consumo de tabaco. Resultados: Prevalencia de consumo de tabaco de 82%, 46.4 puntos porcentuales arriba de la media nacional. Edad de inicio del consumo de tabaco de 14.3 años para fumadores activos y exfumadores, 2.8 años más temprano que los resultados de la ENA 2008. La población estudiada se distribuyó en 3 grupos: fumadores activos, exfumadores y no fumadores representando 59%, 23% y 18% respectivamente. Conclusiones: El tabaquismo es un problema de salud pública con implicaciones graves a largo plazo en la salud de la población; las tendencias muestran una relación inversamente proporcional entre la edad de inicio en el consumo, la cual disminuye presentándose cada vez a edades más tempranas y la prevalencia de consumo, la cual evidencia un franco incremento. Las acciones de salud deberán enfocarse a la prevención primaria y principalmente a la población vulnerable representada por niños, adolescentes y jóvenes.
Complicaciones del dispositivo intrauterino
Authors: Arias-Segura Jorge Omar 
Published: March 2021

El DIU (dispositivo intrauterino) es uno de los métodos anticonceptivos más utilizados en todo el mundo, los principales tipos son el sistema de liberación intrauterina de levonorgestrel (SIU-LNG) y la “T” fabricada con cobre (Copper T380A). A pesar de tener alta eficacia para prevenir embarazos no deseados, su uso no está libre de complicaciones. Una de ellas es la perforación uterina, ésta se relaciona con la pobre experiencia del médico y su incidencia es de 1.3 de cada 1000 inserciones, al existir ésta es factible que el DIU se desplace a órganos contiguos y produzca sintomatología según el sitio al que haya migrado; su manejo aún sigue siendo contradictorio aunque es inevitablemente quirúrgico. Cuando un DIU está instalado adecuadamente y ocurre embarazo las dos principales complicaciones que pueden ocurrir son abortos espontáneos y embarazo ectópico, además de parto prematuro, sangrado, corioamnionitis, desprendimiento de placenta y mayor prevalencia de invasión microbiana a cavidad amniótica. De ser posible deberá ser retirado en etapas tempranas del embarazo. La falta de visualización de los hilos del DIU en el orificio cervical externo es una complicación relativamente frecuente (4,5 a 18%); ante esta situación existen diversas maneras para retirarlo, tanto farmacológicas como instrumentadas, lo cual depende de cada caso en particular.

Background: Staging of multiple myeloma (MM) requires quantification of lesions and serum biomarkers. Sestamibi (MIBI) scan can detect medullary and extra-medullary lesions whereas pathological fracture of MM when associated with osteoblastic activity which can be imaged by methyl diphosphonate (MDP).
Patients and methods: This case report is of a biopsy proven case of MM with serum biomarkers inconclusive for staging. With evidence of multiple pathological rib fractures on conventional radiography, the patient was sent for MDP scan as she was unable to afford any other modality for whole body survey. A complimentary MIBI scan was therefore done.
Results: MDP scan revealed multiple osteoblastic lesions in spine and ribs. The MIBI scan was conclusive for stage II active disease.
Conclusions: MIBI scan added to diagnostic information and aided an inexpensive staging. MIBI scan can be an affordable work-up tool for MM.

Published: March 2021

Background: The effectiveness of antibiotics for the treatment of severe bacterial infections in newborns in resource-limited settings has been determined by empirical evidence. However, such an approach does not warrant optimal exposure to antibiotic agents, which are known to show different disposition characteristics in this population. Here we evaluate the rationale for a simplified regimen of gentamicin taking into account the effect of body size and organ maturation on pharmacokinetics. The analysis is supported by efficacy data from a series of clinical trials in this population.Methods: A previously published pharmacokinetic model was used to simulate gentamicin concentration vs. time profiles in a virtual cohort of neonates. Model predictive performance was assessed by supplementary external validation procedures using therapeutic drug monitoring data collected in neonates and young infants with or without sepsis. Subsequently, clinical trial simulations were performed to characterize the exposure to intra-muscular gentamicin after a q.d. regimen. The selection of a simplified regimen was based on peak and trough drug levels during the course of treatment.Results: In contrast to current World Health Organization guidelines, which recommend gentamicin doses between 5 and 7.5 mg/kg, our analysis shows that gentamicin can be used as a fixed dose regimen according to three weight-bands: 10 mg for patients with body weight &lt;2.5 kg, 16 mg for patients with body weight between 2.5 and 4 kg, and 30 mg for those with body weight &gt;4 kg.Conclusion: The choice of the dose of an antibiotic must be supported by a strong scientific rationale, taking into account the differences in drug disposition in the target patient population. Our analysis reveals that a simplified regimen is feasible and could be used in resource-limited settings for the treatment of sepsis in neonates and young infants with sepsis aged 0–59 days.

Abstract
The effects of ultra-high-pressure annealing (UHPA) on the surface of Mg-ion-implanted GaN were investigated by X-ray photoelectron spectroscopy (XPS). After Mg ion implantation or Mg–N co-implantation, GaN was annealed at 1400 °C for 5 min under a nitrogen pressure of 1 GPa. No deterioration of the surface stoichiometry occurred after UHPA despite the extremely high annealing temperature. The angle-resolved XPS with calibration showed that the surface Fermi level was pinned at 0.5 eV from the conduction band edge after dehydrogenation subsequent to UHPA. However, the absence of pinning at the charge neutrality level showed that surface disorder was absent after UHPA. The surface photovoltaic effect as evidence of the achievement of p-type conduction even in the near-surface region was more remarkable for Mg–N-ion-implanted samples after dehydrogenation subsequent to UHPA. There is the possibility that the density of N-vacancy-related defects was reduced more by Mg–N co-implantation.
Single-chip mixer-based subarray beamformer for sub-Nyquist sampling in ultrasound imaging
Authors: Kanemoto Daisuke , Spaulding Jonathon , Murmann Boris 
Published: March 2021

Abstract
Compressed sensing (CS) has been proposed as a method of breaking the seemingly inherent tradeoff between sampling rate and resolution in a variety of applications, such as ultrasound imaging. Although various studies have demonstrated the effectiveness of using CS for sub-Nyquist sampling in ultrasound imaging, a dedicated integrated circuit (IC) has not yet been presented. This work introduces a single-chip mixer-based subarray beamformer, an important component for sub-Nyquist sampling in a CS ultrasound imaging system. The beamformer chip, which performs mixing, filtering, and summation of delayed signals within a subarray, is implemented using a single operational transconductance amplifier. We evaluated the performance of the proposed mixer-based subarray beamformer circuit fabricated using a 65 nm CMOS process with 0.4 mW ch−1 power consumption from a 1.2 V supply. Measurement results indicate that the prototype chip is suitable for subarray beamforming with a 5 ns resolution digital mixing sequence. The IC presented here is the first known implementation of a mixer-based subarray beamformer for sub-Nyquist sampling in ultrasonic applications and is expected to reduce sampling data requirements by a factor of 32.

Authors: Zhang Shengdong , You Shihui , Li Wei 
Published: March 2021

Abstract
A structure of tunable magnetorheological mechanical topological insulator that uses magnetorheological elastomers as matrix and pure iron as scatterer is designed. By changing the external magnetic field, the elastic modulus of the matrix is affected, and the size and width of the bandgap are adjusted to give the structure adjustability. The waveguide characteristics, the adjustability of topology edge state, the effect of point defects, and the time-domain characteristics of the structure are studied by the finite element method. The tunable range of the structure is increased by 446%; the elastic wave can propagate well in the linear channel and Z channel, there is a certain loss of the elastic amplitude at the output; the point defects have a great influence on the transmission loss, and the abrupt peak value is easy to appear, and there is a “transition region” near the upper and lower boundaries.

Abstract
Thermodynamic analysis and experimental demonstration of β-Ga2O3 growth by metalorganic vapor phase epitaxy using triethylgallium (TEG) and oxygen (O2) precursors were performed. Thermodynamic analysis revealed that the O2 supplied is preferentially used for the combustion of hydrocarbons and H2 derived from TEG. Therefore, the use of high growth temperatures and high input VI/III ratios is essential for the complete combustion of hydrocarbons and H2, and β-Ga2O3 growth. The use of an inert gas as the carrier gas was also determined as necessary to grow β-Ga2O3 at high temperatures. Based on these results, a (

The existence of a Deed Witness is part of the formal aspect of the deed. Without a witness deed, t the notary deed as a Notary Deed, but only has the power of proof as an underhand deed. In addition, the actions of Notary employees as witnesses to deeds in each Notary’s deed are included in the notary fi eld, so that if it is linked to Article 16 paragraph (1) letter f of the Notary Position Law regarding keeping everything concerning deeds made by Notaries, the employees should a notary as a witness to the deed must be able to keep the contents of the deed confi dential. This article intends to fi nd out about the process of summoning notary employees who are witnesses to the deed for investigation and trial in connection with the confi dentiality of the contents of the deed and protecting the confi dentiality of the contents of the deed in the investigation and judicial process involving notary offi ce employees as witnesses to the deed. The results show that summoning notary employees who are deed witnesses for investigation and trial based on UUJN is that there are no rules for special procedures for calling witnesses to deeds in the investigation and trial process. A witness to deed does not have the right of refusal as a notary, therefore what applies is the provision as reference to KUHAP and HIR/Rbg. Protection of the confi dentiality of the contents of the deed in the investigation and judicial process involving notary offi ce employees as witnesses to the deed that there is no obligation for notary employees who are witnesses to the deed to keep the contents of the deed secret during the investigation and trial process. Notary employees who are witnesses to the deed do not completely violate the law because there are no rules in UUJN that regulate the oath to keep the contents of the deed confi dential
