Handling this process adequately will allow those departments to operate efficiently. Most of its concerns are related to its effectiveness due to the short timeframes that clinical staff have during the process and the lack of valuable, timely and pertinent information available. In several contexts, this problem has been addressed by using clinical decision support systems. However, there is not enough information about architectural approaches dealing with key quality attributes and restrictions involved in those systems. This paper aims to analyze and discuss a feasible architectural approach to implement a clinical decision support system for clinical triage by adapting proposals from other scenarios. As main contribution, this proposal describes the architecture design process applied through a well-known standard and emphasizes tactics for performance, availability and security. For this purpose, an attribute-driven design method was followed, concluding that it is a convenient approach because it allows to iterate easily the entire system by prioritizing key elements. The achieved results are useful for architects, implementers, practitioners and researchers to extend the architecture and apply it.

Since Flexible AC Transmission Systems (FACTS) devices are an increasingly widespread solution to these issues, it is important to study how their allocation procedure should be done. This paper seeks to assess the influence of load share in FACTS devices allocation. Despite this interest, researchers, as well as system planners, have mainly focused on studying single power system configuration rather than using a wider approach. Keeping this in mind, we have iteratively created several load share scenarios based on an IEEE 14-bus test system. Subsequently, we have applied an heuristic procedure in order to demonstrate how load share may affect the results of the FACTS devices allocation procedure. Additionally, we have compared results from two different objective functions so as to evaluate our proposal. Finally, we have pro...

These characteristics can affect the performance of satellite tracking since they limit their movements. For this reason, it is proposed a Stewart platform towards the reorientation system that can accept accelerations and higher speeds during its movement, support large loads that have a higher rigidity and precision to be considered by six actors in parallel and finally, have a better follow-up of your six degrees of freedom. The demand for precision for satellite tracking is high, to determine the accuracy of the Stewart platform, a sensitivity analysis is performed that requires information on the design parameters that must be considered to perform a task with precision. Through the numerical simulations with t...

S-values and direct damage to the DNA were calculated representing the cell (C) and the cell nucleus (N) with concentric spheres of 5 μm and 4 μm in radius, respectively. The considered "target"←"source" configurations, including the cell surface (Cs) and cytoplasm (Cy), were: C←C, C←Cs, N←N, N←Cy and N←Cs. Ionization cluster size distributions were also calculated in a cylinder immersed in water corresponding to a DNA segment of 10 base-pairs in length (diameter 2.3 nm, length 3.4 nm), modeling a radioactive point source moving from the central axis to the edge of the cylinder. For that, the first moment (M1) and cumulative probability of having a cluster size of 2 or more ionizations in the cylindrical volume (F2) were obtained. Finally, the direct damage to the DNA was estimated by quantifying double-s...

It is well-known that under competition for the exchanged metabolite, concentration gradients constrain the distances over which interactions can occur. However, interaction distances are typically quantified in two-dimensional systems or without accounting for competition or other metabolite-removal, conditions which may not very often match natural ecosystems. We here analyze the impact of cell-to-cell distance on unidirectional cross-feeding in a three-dimensional system with competition for the exchanged metabolite. Effective interaction distances were computed with a reaction-diffusion model and experimentally verified by growing a synthetic consortium of 1 µm-sized metabolite producer, receiver and competitor cells in different spatial structures. We show that receivers cannot interact with producers ∼15 µm away from them, as product concentration gradients flat...

Patient reported occasional diarrhea with 4 bowel movements a day, without mentioning blood or mucus. There was no growth of germs in the cultures performed and the antibiotic therapy employed did not improve the condition. The patient underwent biopsy of the lesions, which showed granuloma sketches (no necrosis, no foreign body granuloma characteristics), suggesting a cutaneous manifestation of Crohn's disease. Computed tomography (CT) with enterotomography visualization pattern without evidence of lesions. Colonoscopy showed no alterations and serial biopsies did not indicate acute inflammatory symptoms. Anorectal ultrasonography showed complex fistulas in the upper, middle and lower anal canal, suggesting perineal aggression secondary to CD. In a joint decision between gastroenterologists, pediatricians, dermatologists and coloproctologists, it was decided to introduce Adalimumab, but with slight improvement. Symptoms became more exuberant after two months, with extensive involvement of the perineum and buttocks, with apparent secondary bacterial infection. Proceeding with new hospitalization, antibiotic therapy (ciprofloxacin and clindamycin) and new biopsies, which this time also showed foreign body granulomas, suggestive of SH. Patient had significant improvement of symptoms with antibiotic therapy for 3 months, associated with corticotherapy. Adalimumab was prescribed after antimicrobial therapy to reduce infectious risk. DISCUSSION: The differential diagnosis between perianal CD and SH is a challenge, often delaying treatment. Although SH is admittedly an EIM of CD, association in this disease phenotype is rare, as demonstrated by the study by Kamal N. (2016), where the association of CD and SH was investigated over a 10-year period, and only found 15 patients where 73% had perianal CD. Biological anti-TNF therapy may be effective, although many cases still require surgical intervention. In the case of undiagnosed SH, immunosuppressive therapies may aggravate a subclinical infectious process exposing the patient to a poor clinical outcome, as in the case presented. Multidisciplinary assessment is critical and patient reevaluations should be early, especially in pediatric patients where the disease may cause functional and psychological impairment.

For studying the atmospheric behavior horizontally, we used a laser beam that is propagated in a horizontal path at a laboratory room scale and an Optical Turbulence Generator OTG, inserted along the optical path. The airspeed was controlled inside the OTG and some physical variables like temperature and relative humidity were measured for verifying their effects on the local atmosphere. The experimental results show these effects over the angle structure function, the laser beam centroid shifting, and the statistical measurements by using imaging processing which are important to model oneself on environment conditions in an open field.

Additionally, a pre-formed injectable cryogel allows the potential for minimally invasive treatment of bone nonunions that would normally require surgical intervention. Such a defect is due to compromised signaling pathways by biological or biomechanical disturbance during fracture healing. The addition of powdered platelet-rich plasma (PRP) introduces soluble factors normally found in the early inflammatory stages of bone healing, allowing the bone to restart the healing process with the cryogel scaffold as a template for bone formation. A physical characterization of methacrylated alginate (MAA) and PRP-loaded cryogels was performed to determine the most suitable fabrication methods for bone applications. Further investigations were performed to assess cell proliferation and infiltration of MG-63 cells on the scaffolds, the rate of PRP elution, and the bioactive molecules being eluted at various time points. In this study, it was found that higher concentrations of PRP and MAA caused an increase in mechanical stiffness; compromising the shape memory properties of the cryogel. However, the addition of freeze-thaw cycles increased the porosity of the matrix while providing a more compressible scaffold that eluted PRP at a faster rate.

We examined associations of maternal medical comorbidities with cesarean delivery among nulliparous, term, singleton, vertex (NTSV) deliveries in Texas. Nulliparous, term, singleton, vertex deliveries to women aged 15-49 years were identified using the 2015 Texas birth file (Center for Health Statistics, Texas Department of State Health Services). A risk factor index was constructed (score range 0-4), including preexisting/gestational diabetes mellitus, preexisting/gestational hypertension/eclampsia, infertility treatment, smoking during pregnancy, and prepregnancy overweight/obesity, and categorized as 0, 1, 2, and 3+ based on the number of risk factors present. Multivariable logistic regression analyses were conducted to examine associations between the categorized risk factor index and cesarean delivery, overall and by materna...

Manuka honey (MH), indigenous to New Zealand, contains a Unique Manuka Factor that provides an additional antibacterial agent. While there are many potential benefits to incorporating MH into wounds, there is currently no ideal way to deliver the material to the site of injury. Cryogels are a type of scaffold that possess high porosity, mechanical stability, and a sponge-like consistency. This study uniquely incorporates varying amounts of MH into cryogel scaffolds, utilizing its properties in a sustained release fashion to assist in the overall healing process, while using the cryogel structure as a tissue template. All cryogels were evaluated to determine the effects of MH on porosity, swelling potential, mechanical durability, and cell compatibility. The release of MH was also quantified to evaluate bacterial clearance potential, and the scaffolds were m...

There are different architectural approaches for implementing CDSS. Some of these approaches are based on cloud computing, which provides on-demand computing resources over internet. The goal of this paper is to determine and discuss key issues and approaches involving architectural designs in implementing a CDSS using cloud computing. To this end, we performed a standard Systematic Literature Review (SLR) of primary studies showing the intervention of cloud computing on CDSS implementations. Twenty-one primary studies were reviewed. We found that CDSS architectural components are similar in most of studies. Cloud-based CDSS are most used in Home Healthcare and Emergency Medical Systems. Alerts/Reminders and Knowledge Service are the most common implementations. Major challenges are around security, performance and compatibility. We concluded on the benefits of implementing a cloud-based CDSS, since it allows cost-efficient, ubiquitous and elastic computing resources. We highlight that some studies show weaknesses regarding the conceptualization of a cloud-based computing approach and lack of a formal methodology in the architectural design process.
