Clinical utility of universal antigen rapid test (ART) in the pediatric setting is unknown. We aimed to assess the performance and utility of universal ART in hospitalized children (≥5-year-old) to prevent nosocomial COVID-19 transmission.

Cross-sectional study involving all hospitalized pediatric patients aged ≥5-year-old from 2 periods during Omicron wave. Clinical data, ART and polymerase chain reaction test results were collected.

A total of 444 patients were included from the 2 study periods, and 416 patients (93.7%) had concordant results between ART and polymerase chain reaction. The overall sensitivity and specificity of ART were 83.3% (95% CI 75.2-89.3) and 97.5% (95% CI 95.0-98.8), respectively. Negative predictive values of ART between the Omicron emergence and Omicron peak periods for a probable case group were 71.4% and 66.7%, respectively, and for a suspect case group 91.4% and 75.0%, respectively. Negative predictive values for an unlikely case group was >95% in both periods. Positive predictive value of ART was >85% for probable and suspect case groups in both periods. Seventy-five percent of patients (n=15) who were incorrectly classified as SARS-CoV-2 negative by ART had potentially viable virus. check details No large nosocomial transmission clusters were detected.

Universal ART screening may limit nosocomial outbreaks in hospitalized children. The performance can be optimized by considering clinical symptoms, exposure and periods within COVID waves.

Sphingomonas paucimobilis, an aerobic, non-fermentative, Gram-negative opportunistic bacillus, can colonize everywhere in hospital settings where water is used. We reported a hospital S paucimobilis outbreak that persisted for nearly 2 years despite all necessary preventive measures.

Over a period from February 13, 2020 to December 3, 2021, 67 patients were identified to have S paucimobilis as documented by positive cultures from clinical samples, along with 19 positive environmental samples.

Bacterial regrowth for molecular analysis could be obtained in 49 isolates (39 clinical, 4 extracorporeal membrane oxygenation (ECMO) water heater devices, 1 unused mouthwash solution, 5 water samples from thoracic drainage aspirators). Two distinct clonally indistinguishable genotypes were detected in AP-PCR and PFGE analyses, with 100% consistency. The main cluster was obtained consistently throughout the outbreak from 30 samples (61.2% 24 clinical, 4 ECMO, 1 unused mouthwash solution, 1 water sample from the thodevices, with records of pre- and post-disinfection procedures is of paramount importance for complete elimination of the source of infection.
To investigate the amount of time spent in periodic breathing and its consequences in infants born preterm before and after hospital discharge.

Infants born preterm between 28-32weeks of gestational age were studied during daytime sleep in the supine position at 32-36weeks of postmenstrual age (PMA), 36-40weeks of PMA, and 3months and 6months of corrected age. The percentage of total sleep time spent in periodic breathing (% total sleep time periodic breathing) was calculated and infants were grouped into below and above the median (8.5% total sleep time periodic breathing) at 32-36weeks and compared with 36-40weeks, 3 and 6months.

Percent total sleep time periodic breathing was not different between 32-36weeks of PMA (8.5%; 1.5, 15.0) (median, IQR) and 36-40weeks of PMA (6.6%; 0.9, 15.1) but decreased at 3 (0.4%; 0.0, 2.0) and 6months of corrected age 0% (0.0, 1.1). Infants who spent above the median % total sleep time periodic breathing at 32-36weeks of PMA spent more % total sleep time periodic breathing at 36-40weeks of PMA (18.1%; 7.7, 23.9 vs 2.1%; 0.6, 6.4) and 6months of corrected age 0.9% (0.0, 3.3) vs 0.0% (0.0, 0.0).

Percentage sleep time spent in periodic breathing did not decrease as infants born preterm approached term corrected age, when they were to be discharged home. High amounts of periodic breathing at 32-36weeks of PMA was associated with high amounts of periodic breathing at term corrected age (36-40weeks of PMA), and persistence of periodic breathing at 6months of corrected age.

In some patients with progressive fibrosing interstitial lung disease (ILD), disease is caused by carriage of a mutation in a surfactant-related gene (SRG) such as SFTPC, SFTPA2 (SFTP), or ABCA3. However, no aggregated data on disease evolution and treatment outcome have been presented for these patients.

In adult patients with ILD with an SRG mutation, what is the course of lung function after diagnosis and during treatment and the survival in comparison with patients with sporadic idiopathic pulmonary fibrosis (sIPF) and familial pulmonary fibrosis (FPF)?

We retrospectively examined the clinical course of a cohort of adults with an SRG mutation by screening 48 patients from 20 families with an SRG mutation for availability of clinical follow-up data. For comparison, 248 patients with FPF and 575 patients with sIPF were included.

Twenty-three patients with ILD (median age, 45 years; 11 men) with an SRG mutation fulfilled criteria. At diagnosis, patients with an SRG mutation were younger and less ofteed survival despite possible beneficial effects of treatment.
This study showed that patients with ILD with an SRG mutation experience progressive loss of lung function with severely reduced survival despite possible beneficial effects of treatment.The aim of the study is to characterize and hierarchically modify chitosan using partially lateritized khondalite (PLK) rock. PLK is a metamorphic rock rich in mineral oxides and is not commercialized thus, treated as a mining reject. Chitosan was sequentially altered to Chitosan-PLK (Ch-PLK) and Chitosan-PLK-Epichlorohydrin (Ch-PLK-ECH) and both the materials were characterized by FT-IR, SEM, EDX, XRD, XRF and BET surface area analysis. The adsorbents were used for removal of cyanide ions from aqueous solution using batch adsorption experiments. The experiments were performed varying operational parameters and were optimized using RSM. The conditions optimized by RSM were carried out, more than 90 % of CN- adsorption was observed. The isotherm and kinetics studies have shown that the adsorption process fitted well with Langmuir isotherm model and pseudo second order kinetics. Using Langmuir isotherm, the maximum adsorption capacities of Ch-PLK and Ch-PLK-ECH towards cyanide ions at 30 °C were found to be 23.98 mg g-1 and 65.27 mg g-1 respectively. Thermodynamic studies described that adsorption process was spontaneous, enthalpy-driven over entire temperature range. Column studies established that the adsorbents may be applicable to large volume of samples. The adsorbents were tested for regeneration for 5 adsorption-desorption cycles suggesting reusability of the materials.Bacteriophage-derived endolysins and bacterial autolysins (hereinafter lysins) represent a completely new class of efficient antibacterials. They prevent the development of bacterial resistance and help protect commensal microbiota, producing cell wall lysis. Here we have investigated whether the acquisition of enzymatic active domains (EADs) and cell wall binding domains (CWBDs) of balancing efficiencies could be a way of tuning natural lysin activity. The concept was applied to produce a chimeric lysin of superior antibacterial capacity using the endolysin Skl and the major pneumococcal autolysin LytA. Combination of the Skl EAD and the cell wall choline-binding domain (CBD) of LytA in the chimera QSLA increased the bacterial killing by 2 logs or more compared to parental enzymes at an equal concentration and extended the substrate range to resistant and emergent pneumococci and other pathogens of the mitis group. Contrarily, QLAS, containing LytA EAD and Skl CBD, was inactive against all tested strains, although domain structures were preserved and hydrolysis of purified cell walls maintained in both chimeras. As a whole, our study provides a novel clue to design superior lysins to fight multidrug-resistant pathogens based on domain selection, and a powerful in-vivo active lysin (QSLA) with promising therapeutic perspectives.Structural properties and aggregation tendency can be significantly influenced by histidine behaviors (histidine on Nδ-H state is defined as δ, likewise, Nε-H ε and both Nδ-H and Nε-H p). In current study, we investigated structural properties of Aβ(1-40) peptide during protonation evolution stage of one, two, and three by total 19 independent replica exchange molecular dynamics simulations using implicit solvent. Our results show that any kind of protonated state will promote β-sheet structure formation in comparison with deprotonated (εεε). With increase in number of protonation, the lowest β-sheet content increased. The highest averaged β-sheet structure content was detected in (δpδ) (46.0 %), (εpp) (36.8 %), and (ppp) (16.0 %) in each protonation stage. With three β-strand structures, (δpδ) shows more stable features and high hydrophobic properties. Further analysis confirmed that H13 and H14 are more important than H6. Specifically, H13 and H14 have a synergistic effect for structural formations by controlling H-bond networks in H13(p) with V39/V40 and H14(p/δ) with G37/G38. Finally, the Pearson correlation coefficient results confirmed that experimental result (ref. 44) is corresponding to our (εpp) system. Our current study will be conducive to understanding the effects of the histidine behaviors, it provides new insights for exploration protein folding and misfolding processes.Marine polysaccharides are a kind of natural polysaccharides which isolated and extracted from marine organisms. Now some marine polysaccharides, such as chitosan, sodium alginate and agar, have been proven to exhibit antibacterial, antioxidant functions and biocompatibility, which are often used to preserve food or improve the physicochemical properties of food. However, they still have the defects of unsatisfactory preservation effect and biological activity, which can be remedied by its modification. Chemical modification is the most effective of all modification methods. The advances in common chemical modification methods of chitosan, sodium alginate, agar and other marine polysaccharides and research progress of modified products in food processing and preservation were summarized, and the influence of additional reaction conditions on the existence of chemical modification sites of polysaccharides was discussed. The modification of functional groups in natural marine polysaccharides leads to the change of molecular structure, which can improve the physical, chemical and biological properties of marine polysaccharides. Chemically modified products have been used in various fields of food applications, such as food preservatives, food additives, food packaging, and food processing aids. In general, chemical modification has excellent potential for food processing and preservation, which can improve the function of marine polysaccharides.
