Published: October 2024

Background: Triphasic waves (TWs) on electroencephalograms (EEGs) have predominantly been observed in adults, often associated with Creutzfeldt‒Jakob disease and metabolic encephalopathy. However, TWs have also been linked to various nonmetabolic and structural abnormalities. Additionally, reports of TWs in children are rare.
Case Presentation: We present the case of an 8-year and 5-month-old boy with basal ganglia lesion who exhibited TWs in the local C3 lead on electroencephalography. Subsequent EEGs revealed no additional abnormalities. During the follow-up at 1 year and 8 months, there was no significant change in the patient's condition.
Conclusion: Triphasic waves can occur in children with basal ganglia lesions, but their underlying causes may differ from those previously reported. Further research is needed to elucidate the mechanisms and clinical significance of TWs in pediatric patients.

Published: October 2024

Background: Post-stroke depression (PSD) is a common complication, occurring in approximately one-third of these patients. The neurological symptoms of PSD affect patients' daily life and subsequent recovery. Analyzing the pathogenesis of post-stroke depression from a psychological perspective, it was found that PSD patients often feel despair and anxiety, and it is crucial to explore non-pharmacological ways to improve post-stroke depressive symptoms. A combination of exercise and rich environmental stimulation (RES) has been found effective in improving post-stroke depressive symptoms. Therefore, this study aimed to explore the effects of exercise and rich environmental stimulation on PSD in rats and their potential underlying mechanisms and to provide a theoretical basis for managing PSD.
Methods: The PSD rat model was constructed, and the depression-like behaviors of rats in each group were evaluated using the open field test (OFT), sucrose preference test (SPT), and forced swimming test (FST). Moreover, changes in the morphological behavior of rat hippocampus were observed using hematoxylin-eosin (HE) staining and Nissl staining. The expression levels of 5-hydroxytryptamine (5-HT) and norepinephrine (NE) in hippocampus tissues were assessed using enzyme linked immunosorbent assay (ELISA), and the levels of tryptophan-related proteins were determined employing western blot analysis. Additionally, a kynurenine-3-monooxygenase (KMO) inhibitor was administered to the combined stimulation group, and the levels of tryptophan (TRP), 5-HT, kynurenine (KYN), 3-hydroxy-kynurenine (3-HK), and quinolinic acid (QA) were evaluated using liquid chromatography mass spectrometry/mass spectrometry (LC-MS/MS).
Results: Treadmill exercise combined with rich environmental stimulation significantly reduced the immobility time in the FST (p < 0.01), increased the exploratory behavior in the OFT (p < 0.05), and increased the sucrose water consumption in the SPT (p < 0.01), indicating that the depression-like behavior was improved. Treadmill exercise combined with rich environmental stimulation also improved the shape of the damaged hippocampus and increased the number of neurons in the hippocampus. Additionally, treadmill exercise combined with rich environmental stimulation significantly increased the levels of 5-HT and NE in hippocampus tissues (p < 0.01) and decreased KMO protein level (p < 0.01). In the KMO inhibitor group, the neural function was efficiently restored, the levels of 3-HK, QA, and KMO in the hippocampus were substantially reduced (p < 0.01), and the expression level of 5-HT was increased (p < 0.01).
Conclusions: Exercise stimulation combined with enriched environmental stimuli alleviates post-stroke depression in rats, and the underlying mechanisms may be related to TRP/KYN/3-HK/QA excitotoxicity pathways and increased 5-hydroxytryptamine levels.

Published: October 2024

In our 19 years’ experience at King Chulalongkorn Memorial Hospital, we were able to observe 21 pediatric cases with anaplastic large cell lymphoma (ALCL). Of these 21 cases, 4 (19% of ALCL cases) had concurrent hemophagocytic lymphohistiocytosis (HLH). All developed fever, lymphadenopathy and exaggerated signs of capillary leakage syndrome such as generalized edema, pleural effusion or ascites. The hyperinflammation was demonstrated with fever, hypoalbuminemia and elevated inflammatory markers. A high index of suspicion is warranted to recognize concurrent HLH when patients develop cytopenia, splenomegaly, liver dysfunction and pleural or pericardial effusions. For HLH with unknown etiology but with lymphadenopathy, lymph node biopsy should be considered as a part of secondary HLH workup to rule out malignant-associated hemophagocytic syndrome. Treatment with lymphoma-directed therapy should not be contraindicated once a diagnosis of ALCL is made. Instead, one should be cautious whenever a hyperinflammatory state and multi-organ dysfunction exists because HLH-sensitive agents such as corticosteroid, etoposide, cyclosporin A, cyclophosphamide, IVIG and others should be urgently administrated. The mortality was quite high (50%) in our institution. Initial treatment with HLH protocol saved the lives of the other 2 patients (50%), both of whom were cured later with lymphoma-directed protocol.

Background
Becoming a mother is a very important process because of the impact it can have on women and their families. Currently, there is no validated questionnaire that evaluates the process of becoming a mother in the Spanish population. Moreover, no consistent results have been obtained to identify significant differences between primiparous and multiparous mothers.

Aim
(1) Linguistic and metric validation of the Being a Mother scale (BaM-13) in the Spanish population, (2) analysis of possible differences between primiparous and multiparous mothers’ experience of motherhood.

Methods
Instrumental design. In 2016–2017, a sample of 579 mothers with children between 6 and 11 months of age completed the Spanish version of BaM-13. The instrument was translated using forward and back translation. Construct validity, internal consistency, and criterion validity were empirically analyzed.

Results
Factorial analyses showed that the scale presented two adequate factors. Internal consistency of the global scale (α = 0.818, ω = 0.861), the Postnatal bonding factor (α = 0.773, ω = 0.784), and the Adult’s experience factor (α = 0.710, ω = 0.721) was adequate. Significant associations were found with postpartum depression (r = 0.560), parental competence (r = − 0.584) and postnatal bonding (r = − 0.327). In terms of parity, primiparous mothers have greater difficulty in postnatal bonding, compared to multiparous mothers (p = 0.006).

Conclusions
The Spanish version of the BaM-13 scale is valid for measuring mothers’ experience of motherhood in a wide range of domains. The findings of the study show the importance of considering parity in the experience of becoming a mother, highlighting the approach to postnatal bonding in primiparous mothers. Additionally, we underline that it should not be assumed that multiparous mothers experience fewer difficulties in their motherhood process.

Published: October 2024

Objective
To assess the efficacy and safety of intracavitary electrocardiography (IC-ECG)-guided peripherally inserted central catheter (PICC) placements in pediatric patients, emphasizing improvements over traditional placement methods.

Methods
A literature search was conducted in April 2024 across PubMed, Cochrane Library, and EMBASE. Studies focusing on pediatric patients and reporting the efficacy and safety of IC-ECG-guided PICC placement via the upper extremity were included. This study was registered with the PROSPERO database (CRD42024549037) in accordance with PRISMA guidelines.

Results
Eleven studies were included, comprising five randomized controlled trials (RCTs) and six quasi-experimental studies. The pooled analysis showed that IC-ECG had an applicability and feasibility of 97% and 98%, respectively. The first puncture success rate was 91%, and the overall success rate was 98%. Sensitivity and specificity were 97% and 80%, respectively. IC-ECG significantly reduced overall complications compared to traditional methods (RR: 0.31, 95% CI [0.20–0.46], p < 0.00001), particularly in phlebitis (RR: 0.25, 95% CI [0.11–0.57], p = 0.001) and arrhythmias (RR: 0.09, 95% CI [0.01–0.70], p = 0.021). Similar results were observed in neonates. Only one case of catheter-related bloodstream infection (CRBSI) was reported, and no arrhythmia events were noted.

Conclusion
IC-ECG-guided PICC placement is a highly effective and safe method for pediatric patients, including neonates, offering significant advantages over traditional techniques. Further high-quality studies are needed to standardize procedural techniques and explore cost-effectiveness.

Chromodomain helicase DNA binding proteins (CHDs) are characterized by N‐terminal tandem chromodomains and a central adenosine triphosphate‐dependent helicase domain. CHDs govern the cellular machinery's access to DNA, thereby playing critical roles in various cellular processes including transcription, proliferation, and DNA damage repair. Accumulating evidence demonstrates that mutation and dysregulation of CHDs are implicated in the pathogenesis of developmental disorders and cancer. However, we know little about genomic and transcriptomic alterations and the clinical significance of most CHDs in human cancer. We used TCGA and METABRIC datasets to perform integrated genomic and transcriptomic analyses of nine CHD genes in more than 10 000 primary cancer specimens from 32 tumor types, focusing on breast cancers. We identified associations among recurrent copy number alteration, gene expression, clinicopathological features, and patient survival. We found that CHD7 was the most commonly gained/amplified and mutated, whereas CHD3 was the most deleted across the majority of tumor types, including breast cancer. Overexpression of CHD7 was more prevalent in aggressive subtypes of breast cancer and was significantly correlated with high tumor grade and poor prognosis. CHD7 is required to maintain open, accessible chromatin, thus providing fine‐tuning of transcriptional regulation of certain classes of genes. We found that CHD7 expression was positively correlated with a small subset of classical oncogenes, notably NRAS, in breast cancer. Knockdown of CHD7 inhibits cell proliferation and decreases gene expression of several CHD7 targets, including NRAS, in breast cancer cell lines. Thus, our results demonstrate the oncogenic potential of CHD7 and its association with poor prognostic parameters in human cancer.
On the choice of the demand and hydraulic modeling approach to WDN real‐time simulation
Authors: Creaco Enrico , Pezzinga Giuseppe , Savic Dragan 
Published: June 2017

AbstractThis paper aims to analyze two demand modeling approaches, i.e., top‐down deterministic (TDA) and bottom‐up stochastic (BUA), with particular reference to their impact on the hydraulic modeling of water distribution networks (WDNs). In the applications, the hydraulic modeling is carried out through the extended period simulation (EPS) and unsteady flow modeling (UFM). Taking as benchmark the modeling conditions that are closest to the WDN's real operation (UFM + BUA), the analysis showed that the traditional use of EPS + TDA produces large pressure head and water discharge errors, which can be attenuated only when large temporal steps (up to 1 h in the case study) are used inside EPS. The use of EPS + BUA always yields better results. Indeed, EPS + BUA already gives a good approximation of the WDN's real operation when intermediate temporal steps (larger than 2 min in the case study) are used for the simulation. The trade‐off between consistency of results and computational burden makes EPS + BUA the most suitable tool for real‐time WDN simulation, while benefitting from data acquired through smart meters for the parameterization of demand generation models.

AbstractTransport of fine‐grained sediment from unpaved forest roads into streams is a concern due to the potential negative effects of additional suspended sediment on aquatic ecosystems. Here we compared turbidity and suspended sediment concentration (SSC) dynamics in five nonfish bearing coastal Oregon streams above and below road crossings, during three consecutive time periods (“before”, “after road construction/improvement”, and “after forest harvest and hauling”). We hypothesized that the combined effects of road construction/improvement and the hauling following forest harvest would increase turbidity and SSC in these streams. We tested whether the differences between paired samples from above and below road crossing exceeded various biological thresholds, using literature values of biological responses to increases in SSC and turbidity. Overall, we found minimal increases of both turbidity and SSC after road improvement, forest harvest, and hauling. Because flow is often used as a surrogate for turbidity or SSC we examined these relationships using data from locations above road crossings that were unaffected by roads or forest harvest and hauling. In addition, we examined the association between turbidity and SSC for these background locations. We found a positive, but in some cases weak association between flow and turbidity, and between flow and SSC; the relationship between turbidity and SSC was more robust, but also inconsistent among sites over time. In these low order streams, the concentrations and transport of suspended sediment seems to be highly influenced by the variability of local conditions. Our study provides an expanded understanding of current forest road management practice effects on fine‐grained sediment in streams and introduces alternative metrics using multiple thresholds to evaluate potential indicators of biological relevance.

AbstractTo improve lithium and sodium ion battery technology, it is imperative to understand how the properties of the different components are controlled by their chemical structures. Operando structural studies give us some of the most useful information for understanding how batteries work, but it remains difficult to separate out the contributions of the various components of a battery stack (e.g., electrodes, current collectors, electrolyte, and binders) and examine specific materials. We have used operando X‐ray diffraction computed tomography (XRD‐CT) to study specific components of an essentially unmodified working cell and extract detailed, space‐resolved structural information on both crystalline and amorphous phases that are present during cycling by Rietveld and pair distribution function (PDF) methods. We illustrate this method with the first detailed structural examination of the cycling of sodium in a phosphorus anode, revealing surprisingly different mechanisms for sodiation and desodiation in this promising, high‐capacity anode system.

Published: June 2017

AbstractThe discovery of new gigantic molecules formed by self‐assembly and crystal growth is challenging as it combines two contingent events; first is the formation of a new molecule, and second its crystallization. Herein, we construct a workflow that can be followed manually or by a robot to probe the envelope of both events and employ it for a new polyoxometalate cluster, Na6[Mo120Ce6O366H12(H2O)78]⋅200 H2O (1) which has a trigonal‐ring type architecture (yield 4.3 % based on Mo). Its synthesis and crystallization was probed using an active machine‐learning algorithm developed by us to explore the crystallization space, the algorithm results were compared with those obtained by human experimenters. The algorithm‐based search is able to cover ca. 9 times more crystallization space than a random search and ca. 6 times more than humans and increases the crystallization prediction accuracy to 82.4±0.7 % over 77.1±0.9 % from human experimenters.
Adsorptive Separation of CO2 from Flue Gas by Temperature Swing Adsorption Processes
Authors: Salazar Duarte Gabriel , Schürer Benedikt , Voss Christian , Bathen Dieter 
Published: June 2017

AbstractCO2 capture from fossil fueled power stations plays a major role in balancing environmental protection with economic growth. Besides absorption and membrane processes, adsorption processes allow for the removal of CO2 from flue gases and the recovery of the adsorbed CO2 with high purity. In recent years, several pressure swing adsorption as well as temperature adsorption processes have been postulated for carbon capture. In this work, an overview of the different adsorptive methods is exposed with a focus on thermally regenerated adsorption processes. Since the classical temperature swing adsorption process shows some drawbacks, indirectly heated temperature swing adsorption processes have been postulated, which can be categorized into two groups: electro‐thermal swing adsorption and indirect heat transfer.
