Craniofacial condition through pre- in order to post-adolescence.
Disinfection in water treatment and reclamation systems eliminates the potential health risks associated with waterborne pathogens, however it may produce disinfection by-products (DBPs) harmful to human health. Potentially carcinogenic bromate is a DBP formed during the ozonation of bromide-containing waters. To mitigate the problem of bromate formation, different physical/chemical or biological reduction methods of bromate have been investigated. Until now, adsorption-based physical method has proven to be more effective than chemical methods in potable water treatment. Though several studies on biological reduction methods have been carried out in a variety of bioreactor systems, such as in biologically active carbon filters and denitrifying bioreactors, the microbiological mechanisms or biochemical pathways of bromate minimization have not been clearly determined to date. Genetic analysis could provide a broader picture of microorganisms involved in bromate reduction which might show cometabolic or respiratory pathways, and affirm the synergy functions between different contributing groups. The hypothesis established from the diffusion coefficients of different electron donor and acceptors, illustrates that some microorganisms preferring bromate over oxygen contain specific enzymes which lower the activation energy required for bromate reduction. In addition, considering microbial bromate reduction as an effective treatment strategy; field scale investigations are required to observe quantitative correlations of various influencing parameters such as pH, ozone dose, additives or constituents such as ammonia, hydrogen peroxide, and/or chloramine, dissolved organic carbon levels, dissolved oxygen gradient within biofilm, and empty bed contact time on bromate removal or reduction.Phosphorus (P) is a valuable resource, while it is vastly lost with wastewater causing eutrophication. In this study, to recover P, composite biochars were prepared by pyrolyzing biowaste impregnated with FeCl3 or MgCl2. It was found that inherent mineral profiles in the biowastes played important roles in interacting with metal chlorides and determined P sorption and precipitation. Specifically, two biowastes containing distinct mineral contents, sawdust and sediment, were selected as model components, being alone or mixed at 11 (w/w) to prepare biochars with low, moderate and high mineral contents. Results showed that biochar itself could not absorb P, while loading FeCl3 or MgCl2 achieved P recovery rates of approximate 60-100% and 50-100%, respectively, via electrostatic attraction or ligand exchange of PO43- with -OH/-COOH, which was attributed to the enhanced positive charges and -OH/-COOH on the materials by these metal chlorides. OT-82 mw Inherent minerals inhibited FeCl3 transforming into Fe3O4 in pyrolysis and promoted generation of Fe4(PO4)3(OH)3 in P sorption, thus high-mineral content was more appropriate for FeCl3 loading; however, precursors with low-mineral content was suitable for MgCl2 loading, since the bulk-C in biochar acted as porous structure to support MgO crystals with high superficial area (∼255.85 m2 g-1). Besides, FeCl3 and MgCl2 both drove dissolution of inherent minerals significantly, while inherent minerals inhibited release of soluble Fe and Mg2+ into solution, which minimized secondary pollution. This study implied that in constructing composite biochar for catching P, the type of metal chloride should match the inherent minerals in biowastes to maximize P recovery and minimize secondary pollution.Infected abscesses are walled-off collections of pus and bacteria. They are a common sequela of complications in the setting of surgery, trauma, systemic infections and other disease states. Current treatment is typically limited to antibiotics with long-term catheter drainage, or surgical washout when inaccessible to percutaneous drainage or unresponsive to initial care efforts. Antibiotic resistance is also a growing concern. Although bacteria can develop drug resistance, they remain susceptible to thermal and mechanical damage. In particular, short pulses of focused ultrasound (i.e., histotripsy) generate mechanical damage through localized cavitation, representing a potential new paradigm for treating abscesses non-invasively, without the need for long-term catheterization and antibiotics. In this pilot study, boiling and cavitation histotripsy treatments were applied to subcutaneous and intramuscular abscesses developed in a novel porcine model. Ultrasound imaging was used to evaluate abscess maturity for treatment monitoring and assessment of post-treatment outcomes. Disinfection was quantified by counting bacteria colonies from samples aspirated before and after treatment. Histopathological evaluation of the abscesses was performed to identify changes resulting from histotripsy treatment and potential collateral damage. Cavitation histotripsy was more successful in reducing the bacterial load while having a smaller treatment volume compared with boiling histotripsy. The results of this pilot study suggest focused ultrasound may lead to a technology for in situ treatment of acoustically accessible abscesses.
Lobectomy is required in children affected by non-responsive, symptomatic, localized bronchiectasis, but inflammation makes thoracoscopy challenging. We present the first published series of robotic-assisted pulmonary lobectomy in children with bronchiectasis.

Retrospective analysis of all consecutive patients who underwent pulmonary lobectomy for severe localized bronchiectasis (2014-2019) via thoracoscopic versus robotic lobectomy. Four 5mm ports were used for thoracoscopy; a four-arm approach was used for robotic surgery (Da Vinci Surgical Xi System, Intuitive Surgical, California).

Eighteen children were operated (robotic resection, n=7; thoracoscopy, n=11) with infected congenital pulmonary malformation, primary ciliary dyskinesia, and post-viral infection. There were no conversions to open surgery with robotic surgery, but five with thoracoscopy. Total operative time was significantly longer with robotic versus thoracoscopic surgery (mean 247±50 versus 152±57min, p=0.008). There were no significant differences in perioperative complications, length of thoracic drainage, or total length of stay (mean 7±2 versus 8±3 days, respectively). No blood transfusions were required. Two thoracoscopic patients had a type-3 postoperative complication.

Pediatric robotic lung lobectomy is feasible and safe, with excellent visualization and bi-manual hand-wrist dissection - useful properties in difficult cases of infectious pathologies. However, instrumentation dimensions limit use in smaller thoraxes.

Omphalocele is a major congenital anomaly associated with significant morbidity and mortality. Regardless, the influence of maternal use of prescription drugs on the risk of omphalocele has only been addressed in a handful of studies. The aim of this study was to assess the influence of maternal risk factors and prescription drugs in early pregnancy on the risk of omphalocele.

We performed a nationwide register-based case-control study in Finland. The analysis is based on the Finnish Register of Congenital Malformations and Drugs and Pregnancy databases, both upheld by the Finnish Institute for Health and Welfare. All omphalocele cases were identified between Jan 1, 2004, and Dec 31, 2014. Five age-matched controls from the same geographical region were randomly selected for each case. The main outcome measures were maternal risk factors for omphalocele. Our analysis compared the maternal characteristics and the use of prescription drugs during the first trimester of pregnancy between case and control mott risk factors for omphalocele.
In conclusion, these findings may suggest that extended spectrum penicillins in the first trimester reduces the risk of omphalocle formation. Additionally, consistent with earlier studies, previous repeated miscarriages, maternal obesity, and diabetes were significant risk factors for omphalocele.
The present study aimed to investigate the association between estradiol, n-octanoylated, des-octanoylated, total ghrelin, and ghrelin/des-octanoylated ghrelin ratio levels along with pathological parameters and epithelial ovarian cancer (EOC) odds in postmenopausal women.

A case-control study was carried out on 45 patients with EOC and 33 age-matched postmenopausal women as the control group. Plasma levels of estradiol, n-octanoylated, des-octanoylated, and total ghrelin were measured by ELISA method.

Estradiol's plasma levels were significantly higher in patients with EOC than in control women (p <0.001). Although the ratio levels of n-octanoylated, des-octanoylated, total ghrelin, and ghrelin/des-octanoylated ghrelin were not associated with EOC in logistic regression models, estradiol levels were significantly related to the increase in EOC odds (OR 1.083, 95% CI 1.037-1.13, p <0.001). However, estradiol levels in the two first quartiles (Q
, Q
) were associated with decreased odds of EOC (OR 0.011, 95% CI 0.001-0.118, p <0.001, and OR 0.030, 95% CI 0.003-0.284, p=0.002, respectively). For those patients in the third quartile of plasma des-octanoylated and total ghrelin compared to those in the highest (Q4), the multivariate odds ratios of EOC were respectively 0.192 and 0.25.

In conclusion, higher concentrations of des-octanoylated and total ghrelin might be associated with the decreased EOC odds. Furthermore, the findings suggest that high levels of estradiol might be a potential odds factor in EOC, however, lower estradiol levels may have a protective effect on EOC development.

This controller is used for multi-input and multi-output (MIMO) uncertain discrete-time nonlinear systems. This newly developed MTN is dissimilar with the neural network, in which only multiplication and addition are needed for this controller. Thus, real-time control is more easily to be achieved. The theoretical analysis shows that the output errors of the system are convergent and the output signals are semi-globally, uniformly and ultimately bounded. To illustrate the validity of MTN-based adaptive controller (MTNAC), a numerical example is given. The simulation data demonstrate that this MNTAC has better real-time performance and higher robustness compared with neural networks.Unmanned systems like autonomous surface vessels are being enhanced with the communication infrastructure to improve their reliability, efficiency and sustainability. Regardless of the significance advantages, their open communication network and connectivity renders these systems to a variety of cyber-attacks. This paper considers the resilient consensus problem of multi-agent systems (MASs) under an integrity attack. Unlike the existing works in the time domain, a resilient consensus controller is designed and analyzed for MASs in the frequency domain. To this end, analysis and modeling of MASs under the integrity attacks (MU-IA) are addressed in the frequency domain in which each agent is a linear continuous system with an input time delay. A resilient H∞ controller is proposed to tackle the tampering of information due to an integrity attack. The proposed H∞ controller is designed based on an internal stability method for performance tracking and robustness of the MU-IA. A significant strength of this scheme is that the current approach does not enforce any limit on the number of agents or neighboring agents under the integrity attacks.
