RESUMEN
Trichoderma reesei is an economically important enzyme producer with several unique meiotic features. spo11, the initiator of meiotic double-strand breaks (DSBs) in most sexual eukaryotes, is dispensable for T. reesei meiosis. T. reesei lacks the meiosis-specific recombinase Dmc1. Rad51 and Sae2, the activator of the Mre11 endonuclease complex, promote DSB repair and chromosome synapsis in wild-type and spo11Δ meiosis. DNA methyltransferases (DNMTs) perform multiple tasks in meiosis. Three DNMT genes (rid1, dim2 and dimX) differentially regulate genome-wide cytosine methylation and C:G-to-T:A hypermutations in different chromosomal regions. We have identified two types of DSBs: type I DSBs require spo11 or rid1 for initiation, whereas type II DSBs do not rely on spo11 and rid1 for initiation. rid1 (but not dim2) is essential for Rad51-mediated DSB repair and normal meiosis. rid1 and rad51 exhibit a locus heterogeneity (LH) relationship, in which LH-associated proteins often regulate interconnectivity in protein interaction networks. This LH relationship can be suppressed by deleting dim2 in a haploid rid1Δ (but not rad51Δ) parental strain, indicating that dim2 and rid1 share a redundant function that acts earlier than rad51 during early meiosis. In conclusion, our studies provide the first evidence of the involvement of DNMTs during meiotic initiation and recombination.
RESUMEN
This retrospective study assessed the effectiveness and impact of implementing a Modified Early Warning System (MEWS) and Rapid Response Team (RRT) for inpatients admitted to the general ward (GW) of a medical center. This study included all inpatients who stayed in GWs from Jan. 2017 to Feb. 2022. We divided inpatients into GWnon-MEWS and GWMEWS groups according to MEWS and RRT implementation in Aug. 2019. The primary outcome, unexpected deterioration, was defined by unplanned admission to intensive care units. We defined the detection performance and effectiveness of MEWS according to if a warning occurred within 24 h before the unplanned ICU admission. There were 129,039 inpatients included in this study, comprising 58,106 GWnon-MEWS and 71,023 GWMEWS. The numbers of inpatients who underwent an unplanned ICU admission in GWnon-MEWS and GWMEWS were 488 (.84%) and 468 (.66%), respectively, indicating that the implementation significantly reduced unexpected deterioration (p < .0001). Besides, 1,551,525 times MEWS assessments were executed for the GWMEWS. The sensitivity, specificity, positive predicted value, and negative predicted value of the MEWS were 29.9%, 98.7%, 7.09%, and 99.76%, respectively. A total of 1,568 warning signs accurately occurred within the 24 h before an unplanned ICU admission. Among them, 428 (27.3%) met the criteria for automatically calling RRT, and 1,140 signs necessitated the nursing staff to decide if they needed to call RRT. Implementing MEWS and RRT increases nursing staff's monitoring and interventions and reduces unplanned ICU admissions.

PURPOSE: The global prevalence of inflammatory bowel disease (IBD) has steadily risen over the past few decades. Bariatric surgery stands out as an effective strategy for inducing weight loss. This study investigated the impacts of bariatric surgery on the clinical outcomes in patients with IBD. MATERIALS AND METHODS: Data of hospitalized patients aged ≥ 18 years with IBD were extracted from the Nationwide Inpatient Sample (NIS) 2005-2018. The patients were categorized according to whether they underwent bariatric surgery or not. Univariate and multivariable logistic regression analyses were performed to determine the associations between bariatric surgery, prolonged LOS, unfavorable discharge, hospital mortality, and morbidity. RESULTS: Data from 807,843 hospitalized patients with IBD were extracted. After exclusions and propensity-score matching, 80,545 patients were analyzed, with 16,109 undergoing bariatric surgery and 64,436 not. A total of 23% of patients had a prolonged LOS, 8% had unfavorable discharge, and the mortality rate was 1.2%. Multivariable analyses revealed that, compared to patients without bariatric surgery, patients with bariatric surgery had significantly decreased odds of prolonged LOS (adjusted odds ratio [aOR], 0.89; 95% CI 0.85-0.93), unfavorable discharge (aOR, 0.83; 95% CI: 0.77-0.89), and mortality (aOR, 0.54; 95% CI: 0.44-0.67), but had increased odds of morbidity (aOR, 1.09; 95% CI 1.04-1.13). CONCLUSION: In adults with IBD, bariatric surgery is associated with favorable outcomes concerning hospital LOS, discharge status, and mortality. However, the risk of overall morbidity is slightly increased in those who received bariatric surgery compared to those who did not.

BACKGROUND: This study aimed to ascertain if the incorporation of intensity-modulated radiotherapy (IMRT) with chemotherapy (CTx) offered any advantages for patients diagnosed with stage pT3N0 rectal cancer located in the proximal (upper) region following a complete total mesorectum excision (TME). METHODS: We retrospectively examined medical records of stage II/III rectal cancer patients who had undergone CTx or concurrent chemoradiation (CCRT) with IMRT after a successful TME. We juxtaposed a variety of survival outcomes across two patient cohorts. Each outcome was further classified according to Gunderson's risk stratification between proximal and distal (middle and low) rectal cancer patients, and we evaluated the factors associated with each outcome. RESULTS: The median follow-up duration was 4.9 years. Our research comprised 236 rectal adenocarcinoma patients treated at our institution between 2007 and 2019. They received either the CTx (n = 135) or the CCRT (n = 101) with 10-year locoregional recurrence-free survival (LRRFS) of 90.1% and 96.1%, respectively (p = 0.163). However, after performing multivariate adjustments, a pattern emerged hinting at a better LRRFS for the CCRT group (p = 0.052). Perforation had a strong correlation with locoregional recurrence. No significant differences were observed in other survival between the two treatment arms and their respective subgroups. The CCRT group witnessed significantly higher immediate and chronic complications with p = 0.007 and 0.009, respectively. The CCRT group had two secondary cancer-related fatalities (2%, one attributed to IMRT), and another reported by the CTx group (1%). The sole classified locoregional recurrence within the cohort of 37 individuals treated with CTx for proximal pT3N0 rectal cancer was, in fact, the development of sigmoid colon cancer. CONCLUSION: The results suggest that for patients with proximal pT3N0 rectal cancer post-TME, IMRT is better when not combined with CTx, except in highly perilous scenarios or those involving perforation.

Background: Ellagic acid is a natural polyphenol compound found in pomegranates, walnuts, and many berries. It is not easily absorbed, but it could be metabolized to urolithins by the gut microbiota. Urolithin A, one of the ellagic acid metabolites, has been proved to prolong the lifespan of C. elegans and increases muscle function of mice. The purpose of this current study was to analyze the absorption and metabolites of urolithin A and ellagic acid in mice and the anticancer effects of urolithin A, urolithin B, and ellagic acid in colorectal cancer cells. Methods: Urolithin A and urolithin B were synthesized and analyzed by HPLC and NMR. A pharmacokinetic study of urolithin A was performed in mice by analyzing urolithin A and its metabolites in urines. Absorption and biotransformation of ellagic acid were also studied in mice by analyzing the plasma, liver, and feces. The cytotoxicity of urolithin A, urolithin B, and ellagic acid was assayed in SW480, SW620, HCT 116, and HT-29 cells. Results: Urolithin A and urolithin B were synthesized and purified to reach 98.1% and 99% purity, respectively, and the structures were identified by NMR. In urolithin A intake analysis, urolithin A was only detectable at 3 h, not at 6-24 h; it suggested that urolithin A was rapidly metabolized to some unknown metabolites. Using UPLC-MS/MS analysis, the metabolites might be urolithin A 3-O-glucuronide, urolithin A 3-sulfate, and urolithin A-sulfate glucuronide. After feeding mice with ellagic acid for consecutive 14 days, ellagic acid contents could be detected in the fecal samples, but not in plasma and liver, and urolithin A was not detected in all samples. It suggests that ellagic acid is not easily absorbed and that the biotransformation of ellagic acid to urolithin A by intestinal flora might be very low. From the cytotoxicity assay, it was found that there was anticancer effect in urolithin A and urolithin B but not in ellagic acid. In contrast, ellagic acid promoted the proliferation of SW480 and SW620 cells.
RESUMEN
BACKGROUND: Fever can occur after acute myocardial infarction (MI). The influence of body temperature (BT) after hospital arrival on patients with acute MI has rarely been investigated. METHODS: Patients who were diagnosed with acute MI in the emergency department (ED) of a tertiary teaching hospital between 1 January 2020 and 31 December 2020 were enrolled. Based on the tympanic temperature obtained at the ED triage, patients were categorized into normothermic (35.5°C-37.5°C), hypothermic (< 35.5°C), or hyperthermic (> 37.5°C) groups. The primary outcome was in-hospital cardiac arrest (IHCA), while the secondary outcomes were adverse events. Statistical significance was set at p < 0.05. RESULTS: There were 440 enrollees; significant differences were found among the normothermic (n = 369, 83.9%), hypothermic (n = 27, 6.1%), and hyperthermic (n = 44, 10.0%) groups in the triage respiratory rate (median [IQR]) (20.0 [4.0] cycles/min versus 20.0 [4.0] versus 20.0 [7.5], p = 0.009), triage heart rate (88.0 [29.0] beats/min versus 82.0 [28.0] versus 102.5 [30.5], p < 0.001), presence of ST-elevation MI (42.0% versus 66.7% versus 31.8%, p = 0.014), need for cardiac catheterization (87.3% versus 85.2% versus 72.7%, p = 0.034), initial troponin T level (165.9 [565.2] ng/L versus 49.1 [202.0] versus 318.8 [2002.0], p = 0.002), peak troponin T level (343.8 [1405.9] ng/L versus 218.7 [2318.2] versus 832.0 [2640.8], p = 0.003), length of ICU stay (2.0 [3.0] days versus 3.0 [8.0] versus 3.0 [9.5], p = 0.006), length of hospital stay (4.0 [4.5] days versus 6.0 [15.0] versus 10.5 [10.8], p < 0.001), and infection during hospitalization (19.8% versus 29.6% versus 63.6%, p < 0.001) but not in IHCA (7.6% versus 14.8% versus 11.4%, p = 0.323) or any adverse events (50.9% versus 48.1% versus 63.6%, p = 0.258). Multivariable analysis showed no significant association of triage BT with IHCA or any major complication. CONCLUSION: Triage BT did not show a significant association with IHCA or adverse events in patients with acute MI. However, triage BT could be associated with different clinical presentations and should warrant further investigation.

The imbalance of mucosal immunity in the lower gastrointestinal tract can lead to chronic inflammatory bowel diseases (IBDs), including Crohn's disease and ulcerative colitis. IBD is a chronic inflammatory disorder that causes small and/or large intestines ulceration. According to previous studies, recombinant interleukin (IL)-10 protein and genetically modified bacteria secreting IL-10 ameliorate dextran sulfate sodium (DSS)-induced colitis in mice. IL-19 is a transcriptional activator of IL-10 and can alter the balance of T helper 1 (Th)1/Th2 cells in favor of Th2. In this study, we aimed to investigate whether the expression of the murine IL-19 gene carried by Salmonella choleraesuis (S. choleraesuis) could ameliorate murine IBD. Our results showed that the attenuated S. choleraesuis could carry and express the IL-19 gene-containing plasmid for IBD gene therapy by reducing the mortality and clinical signs in DSS-induced acute colitis mice as compared to the untreated ones. We also found that IL-10 expression was induced in IL-19-treated colitis mice and prevented inflammatory infiltrates and proinflammatory cytokine expression in these mice. We suggest that S. choleraesuis encoding IL-19 provides a new strategy for treating IBD in the future.
RESUMEN
This paper aims at unpaired shape-to-shape transformation for 3D point clouds, for instance, turning a chair to its table counterpart. Recent work for 3D shape transfer or deformation highly relies on paired inputs or specific correspondences. However, it is usually not feasible to assign precise correspondences or prepare paired data from two domains. A few methods start to study unpaired learning, but the characteristics of a source model may not be preserved after transformation. To overcome the difficulty of unpaired learning for transformation, we propose alternately training the autoencoder and translators to construct shape-aware latent space. This latent space based on novel loss functions enables our translators to transform 3D point clouds across domains and maintain the consistency of shape characteristics. We also crafted a test dataset to objectively evaluate the performance of point-cloud translation. The experiments demonstrate that our framework can construct high-quality models and retain more shape characteristics during cross-domain translation compared to the state-of-the-art methods. Moreover, we also present shape editing applications with our proposed latent space, including shape-style mixing and shape-type shifting, which do not require retraining a model.
RESUMEN
Background: Emergency department (ED) overcrowding is a public health crisis that affects patient care quality. Space management in the ED can affect patient flow dynamics and clinical practice. We proposed a novel design of the "emergency procedure zone" (EPZ). The purpose of the EPZ was to provide an isolated area for clinical practice and procedure teaching, to ensure a secure area with adequate equipment and monitors, and safeguard patient privacy and safety. This study aimed to analyze the impact of the EPZ on procedural practice and patient flow dynamics. Methods: This study was conducted at the ED of a tertiary teaching hospital in Taiwan. Data were collected from 1 March 2019 to 31 August 2020 (pre-EPZ period) and from 1 November 2020 to 30 April 2022 (post-EPZ period). Statistical analyses were performed using IBM SPSS Statistics software. This study focused on the number of procedures and length of stay in the emergency department (LOS-ED). Variables were analyzed using the chi-square test and Mann-Whitney U test. Statistical significance was defined as p < 0.05. Results: There were 137,141 (pre-EPZ period) and 118,386 (post-EPZ period) ED visits recorded during this period. The post-EPZ period showed a significant increase in central venous catheter insertion, chest tube or pigtail placement, arthrocentesis, lumbar puncture, and incision and drainage procedures (p < 0.001). For patients who were directly discharged from the ED, the post-EPZ period also had a higher percentage of ultrasound studies performed in the ED and a shorter LOS-ED for patients who were directly discharged from the ED (p < 0.001). Conclusions: The establishment of an EPZ in the ED has a positive impact on procedural efficiency. The EPZ improved diagnosis and disposition efficiency, shortened the length of stay, and provided benefits such as improved management, patient privacy, and teaching opportunities.

BACKGROUND: Although some studies have reported evidence of the effectiveness of virtual-reality interventions implemented for children undergoing intravenous (IV) cannulation, children's perceptions of virtual-reality interventions implemented during IV cannulation warrant further exploration. AIMS: To explore the school-aged children's perceptions of interactive virtual-reality interventions implemented before and after IV cannulation. METHODS: A qualitative descriptive study was adopted. Sixty-nine children aged 6-12 years from two medical centers were recruited and interviewed from June to September 2020. After the completion of the immersive virtual-reality scene of IV cannulation before undergoing actual IV cannulation and the emotionally cathartic virtual-reality play after the placement process, individual interviews were conducted with the children in the paediatric wards. Inductive content analysis was performed to analyse children's perceptions. The study complied with the Consolidated Criteria for Reporting Qualitative Research. RESULTS: Three categories related to children's perception of interactive virtual-reality interventions implemented before and after IV cannulation were identified: (1) feelings towards and coping strategies employed during IV cannulation; (2) mental preparation through immersion in the virtual-reality scene; and (3) healing effects of immersive cathartic play. CONCLUSIONS: The findings indicate that interactive virtual-reality interventions can help hospitalised children mentally prepare for medical procedures, obtain knowledge regarding such procedures, and overcome their fear of needles. The children's reported perceptions of the virtual-reality interventions indicated that the interventions were age-appropriate, safe and fun. The results of this study highlight the need to more thoroughly understand the perceptions of hospitalised children and may serve as a reference for designing child-friendly care interventions for nursing practice.

Celiac disease (CD) is a human autoimmune disease triggered by toxic gluten peptides. Recently, oral enzyme therapy has been proposed to ameliorate the health condition of CD patients based on the concept of removing pepsin-insensitive gluten-derived pro-immunogenic peptides. A Burkholderia peptidase, Bga1903, with promising gluten-degrading activity was characterized previously. Here, we report the crystal structure of Bga1903, in which the core has a α/ß/α fold featured with a twisted six-stranded parallel ß-sheet sandwiched between two layers of α-helices. The mutations at the substrate-binding pocket that might enhance the peptidase's affinity toward tetrapeptide PQPQ were predicted by FoldX. Accordingly, four single-substitution mutants, G351A, E380L, S386F, and S387L, were created. The specificity constant (kcat/KM) of wild type toward chromogenic peptidyl substrates Z-HPK-pNA, Z-HPQ-pNA, Z-HPL-pNA, and Z-QPQ-pNA are 30.2, 7.9, 3.3, and 0.79 s-1·mM-1, respectively, indicating that the QPQ motif, which frequently occurs in pro-immunogenic peptides, is not favorable. Among the mutants, E380L loses the hydrolytic activity toward Z-HPK-pNA, suggesting a critical role of E380 in preferring a lysine residue at the P1 position. S387L shows a 17-fold increase in the specificity constant toward Z-QPQ-pNA and hydrolyzes the pro-immunogenic peptides more efficiently than the wild-type peptidase.

BACKGROUND: Aerosols and droplets are the transmission routes of many respiratory infectious diseases. The COVID-19 management guidance recommends against the use of nebulized inhalation therapy directly in the emergency room or in an ambulance to prevent possible viral transmission. The three-dimensional printing method was used to develop an aerosol inhalation treatment mask that can potentially prevent aerosol dispersion. We conducted this utility validation study to understand the practicability of this new nebulizer mask system. RESULTS: The fit test confirmed that the filter can efficiently remove small particles. The different locations of the mask had an excellent fit with a high pressure making a proper face seal usability. The full-face mask appeared to optimize filtration with pressure and is an example of materials that perform well for improvised respiratory protection using this design. The filtering effect test confirmed that the contamination of designated locations could be protected when using the mask with filters. As in the clinical safety test, a total of 18 participants (10 [55.6%] females; aged 33.1 ± 0.6 years) were included in the final analysis. There were no significant changes in SPO2, EtCO2, HR, SBP, DBP, and RR at the beginning, 20th, 40th, or 60th minutes of the test (all p >.05). The discomfort of wearing a mask increased slightly after time but remained within the tolerable range. The vision clarity score did not significantly change during the test. The mask also passed the breathability test. CONCLUSION: The results of our study showed that this mask performed adequately in the fit test, the filtering test, and the clinical safety test. The application of a full-face mask with antiviral properties, together with the newly designed shape of a respirator that respects the natural curves of a human face, will facilitate the production of personal protective equipment with a highly efficient filtration system. METHODS: We conducted three independent tests in this validation study: (1) a fit test to calculate the particle number concentration and its association with potential leakage; (2) a filtering effect test to verify the mask's ability to contain aerosol spread; and (3) a clinical safety test to examine the clinical safety, comfortableness, and visual clarity of the mask.

Bacterial immobilisation is a technique by which bacteria are embedded into or adsorbed onto a carrier material thereby increasing bacterial tolerance to harsh environments. This technique can be used to enhance bacterial activity and to degrade pollutants. Immobilised bacterial beads that contain nanomagnetic particles allow bead recycling and reuse. In this study, our objective was to produce cross-linked nanomagnetic chitosan beads (MCBs) for the biodegradation of benzophenone-type UV filter chemicals such as 2,4-dihydroxybenzophenone (BP-1) and oxybenzone (BP-3). We found that the optimal concentration for creating these MCBs to be 1.2% by weight chitosan and 10% by weight nano-magnetite. We selected and isolated six benzophenone-n (BPs)-biodegrading bacteria identified to be various Pseudomonas spp., a Gordonia sp., and Rhodococcus zopfii; these were used to create MCBs that were able to effectively biodegrade BP-1 or BP-3 as a sole carbon source. Both BPs were effectively biodegraded and mineralised over 8 days in the presence of the selected MCB-immobilised bacterial strains. The highest pseudo-first-order constant rates for BP biodegradation were 8.7 × 10-3 h-1 for BP-1 (strain BP1-D) and 1.02 × 10-3 h-1 for BP-3 (strain BP3-1). The mechanical strength of the MCBs was measured to be above 90% based on recovered weight. The MCBs released their bacteria at rates in the range of 104-105 CFU/day. We also determined the pathway through which the BPs were being aerobically biodegraded based on the GC/MS profiles of the intermediates. Our findings provide a novel strategy for treating BPs via the use of reusable and recyclable MCBs that are cheap, easy and fast to synthesise.

PURPOSE: Obesity has been considered one of the risk factors with more critical disease progression and poor treatment response in rheumatoid arthritis (RA). We herein utilized an extensive, nationally representative database to examine the impact of bariatric surgery on clinical outcomes in RA patients. MATERIALS AND METHODS: This retrospective analysis utilized nationally representative data of the Healthcare Cost and Utilization Project-National Inpatient Sample database (HCUP-NIS) from 2005 to 2018. Associations between bariatric surgery and in-hospital outcomes of RA patients were determined by the univariate and multivariate logistic regression analyses. RESULTS: After 1:4 propensity score (PS) matching, totally 33,075 hospitalized adults with RA were included as primary cohort for subsequent analyses. Among them, 6615 patients had prior bariatric surgery and 26,460 patients had not. After adjusting for relevant confounders in the multivariate analysis, prior bariatric surgery was significantly and independently associated with reduced odds for any morbidity and in-hospital mortality (aOR: 0.41, 95% CI: 0.27-0.61, p < 0.01) as compared with no prior bariatric surgery. Adults with RA who had prior bariatric surgery also had a significantly lower odds for having unfavorable discharge and prolonged length of stay (LOS) as compared with those without bariatric surgery (aOR: 0.43, 95% CI: 0.39-0.46, p < 0.01). CONCLUSIONS: Prior bariatric surgery is associated with better in-patient outcomes among RA, including in-hospital mortality, major morbidities, discharge destination, and LOS.

BACKGROUND/PURPOSE: Interfacility transfer (IFT) in Asian communities is seldom discussed. We aimed to describe the characteristics of IFT in Taiwan and to explore the adequacy of care during transfer. METHODS: A retrospective, cross-sectional, descriptive study was conducted using standardized, paper-based interfacility ambulance transfer records between 1 January 2018 and 31 January 2018 from Tainan City, Taiwan. The mode of patient care needed was classified as advanced life support (ALS) or basic life support (BLS) cares based on clinical conditions. ALS providers were defined as physicians and EMT-Paramedics, while BLS providers were defined as nurse practitioners, nurses, EMT-1s and EMT-2s. RESULTS: Of the 377 (227 [60.2%] were >65 years old; 219 [58.1%] were male) IFTs enrolled in the final analysis, 210 (55.7%) patients met the ALS transfer criteria, with poor consciousness (n = 158), tachypnea (n = 17), tachycardia (n = 5), bradycardia (n = 7), hypertension (n = 12), hypotension (n = 13), hypoxia (n = 4), endotracheal intubation (n = 18), a tracheostomy (n = 25), a precipitous labor (n = 1), and after resuscitation for out-of-hospital cardiac arrest (n = 10) or in-hospital cardiac arrest (n = 3). None of the patients who required ALS care had adequate ambulance staffing. Of the 167 BLS IFTs, 9 (5.4%) patients deteriorated and required ALS care during transportation, which included worsened consciousness (n = 2), tachycardia (n = 1), hypertension (n = 2), hypotension (n = 1), and hypoxia (n = 3). The rates of deterioration during BLS-transferals from the emergency departments, general wards, nursing facilities, and unknown areas were 4.8%, 4.7%, 7.7%, and 7.1%, respectively (p = 0.93). CONCLUSION: The patient care during IFT in Taiwan is inadequate currently and should warrant attention.

PURPOSE: This study aimed to evaluate the effectiveness of an interactive virtual reality (VR) play intervention including instructional play and emotional catharsis play sessions in reducing children's pain and fear during intravenous placement. METHODS: A randomized controlled trial with parallel groups was conducted. The sample consisted of 134 hospitalized children aged 6-12 years (intervention group: n = 69; comparison group: n = 65). The intervention involved one immersive intravenous scene in VR before the actual intravenous placement and one emotional catharsis VR play after injection. The comparison group received an educational photo book about intravenous placement before receiving intravenous placement. The children and their caregivers rated their pain and fear by using the Wong-Baker FACES Pain Rating Scale and the Children's Fear Scale. The time required for successful intravenous insertion was also compared between the two groups. RESULTS: Children's pain (p = .028) and fear scores (p = .004) were significantly lower in the intervention group than in the comparison group. Their caregivers' pain and fear scores (both p < .001) were significantly lower in the intervention group. The time required for successful intravenous insertion did not differ significantly between the intervention and comparison groups. CONCLUSIONS: The interactive play intervention with VR effectively reduced children's levels of pain and fear during the intravenous placement procedure. The results of this study can serve as a reference for the implementation of a feasible, child-friendly care practice for clinical intravenous placement in school-aged children.

A record outbreak of community-spread COVID-19 started on 10 May 2021, in Taiwan. In response to the COVID-19 pandemic, care facilities have adopted various protocols using instant communication technology (ICT) to provide remote yet timely healthcare while ensuring staff safety. The challenges of patient evaluation in the emergency department (ED) using ICT are seldom discussed in the literature. The objective of this study was to investigate the factors influencing the utility of ICT for patient assessment in emergency settings during the pandemic. The patient flow protocol and the ED layout were modified and regionalized into different areas according to the patient's risk of COVID-19 infection. Nine iPads were stationed in different zones to aid in virtual patient assessment and communication between medical personnel. A focus group study was performed to assess and analyze the utility of the ICT module in the ED. Eight emergency physicians participated in the study. Of them, four (50%) had been directly involved in the development of the ICT module in the study hospital. Three main themes that influenced the application of the ICT module were identified: setting, hardware, and software. The setting theme included six factors: patient evaluation, subspecialty consultation, patient privacy and comfortableness, sanitation, cost, and patient acceptability. The hardware theme included six factors: internet connection, power, quality of image and voice, public or personal mode, portable or fixed mode, and maintenance. The software theme included six factors: platform choices, security, ICT accounts, interview modes, video/voice recording, and time limitation. Future studies should focus on quantifying module feasibility, user satisfaction, and protocol adjustment for different settings.

With the continuing rise of lipidomic studies, there is an urgent need for a useful and comprehensive tool to facilitate lipidomic data analysis. The most important features making lipids different from general metabolites are their various characteristics, including their lipid classes, double bonds, chain lengths, etc. Based on these characteristics, lipid species can be classified into different categories and, more interestingly, exert specific biological functions in a group. In an effort to simplify lipidomic analysis workflows and enhance the exploration of lipid characteristics, we have developed a highly flexible and user-friendly web server called LipidSig. It consists of five sections, namely, Profiling, Differential Expression, Correlation, Network and Machine Learning, and evaluates lipid effects on cellular or disease phenotypes. One of the specialties of LipidSig is the conversion between lipid species and characteristics according to a user-defined characteristics table. This function allows for efficient data mining for both individual lipids and subgroups of characteristics. To expand the server's practical utility, we also provide analyses focusing on fatty acid properties and multiple characteristics. In summary, LipidSig is expected to help users identify significant lipid-related features and to advance the field of lipid biology. The LipidSig webserver is freely available at http://chenglab.cmu.edu.tw/lipidsig.
