Next generation sequencing is in the process of evolving from a technology used for research purposes to one which is applied in clinical diagnostics. Recently introduced high throughput and benchtop instruments offer fully automated sequencing runs at a lower cost per base and faster assay times. In turn, the complex and cumbersome library preparation, starting with isolated nucleic acids and resulting in amplified and barcoded DNA with sequencing adapters, has been identified as a significant bottleneck. Library preparation protocols usually consist of a multistep process and require costly reagents and substantial hands-on-time. Considerable emphasis will need to be placed on standardisation to ensure robustness and reproducibility. This review presents an overview of the current state of automation of library preparation for next generation sequencing. Major challenges associated with library preparation are outlined and different automation strategies are classified according to their functional principle. Pipetting workstations allow high-throughput processing yet offer limited flexibility, whereas microfluidic solutions offer great potential due to miniaturisation and decreased investment costs. For the emerging field of single cell transcriptomics for example, microfluidics enable singularisation of tens of thousands of cells in nanolitre droplets and barcoding of the RNA to assign each nucleic acid sequence to its cell of origin. Finally, two applications, the characterisation of bacterial pathogens and the sequencing within human immunogenetics, are outlined and benefits of automation are discussed. OBJECTIVE To review GRADE methodology and discuss the clinical application of conditional recommendations in clinical guidelines, specifically in the context of anaphylaxis. DATA SOURCES Articles describing GRADE, evidence synthesis, evidence to recommendation frameworks, and shared decision making were used to discuss conditional recommendations of the 2020 Anaphylaxis GRADE guideline. STUDY SELECTIONS A narrative review detailing concepts of GRADE and approaches to translate conditional recommendations to individualized and contextualized patient care. RESULTS GRADE methodology encourages a nuanced relationship between certainty of evidence and strength of recommendations. Strengthof recommendation must incorporate key factors including the balance between benefits/harms, patient values /preferences, and resource allocation (costs), with equity, feasibility, and acceptability also often included as considerations. GRADE guidelines provide recommendations that are characterized by directionality (for or against) and strength (strong or conditional). A conditional recommendation is tailored to context and primarily applied through a lens of patient preferences related to the likelihood of outcomes of importance and a shared decision-making approach. While the 2020 Anaphylaxis GRADE guideline better informs the practice of anaphylaxis prevention through (i) identification and mitigation of risk factors for biphasic anaphylaxis and (ii) evaluation of the use of glucocorticoid and/or antihistamine pretreatment, all GRADE recommendations, while directional, are conditional and as such should not be universally applied to every circumstance. CONCLUSION Clinical guidelines provide an important opportunity to critically appraise evidence and translate evidence to practice. Patients, clinicians, and policy makers should appreciate the strength of recommendation and certainty of evidence, and understand how this impacts guideline applicability and implementation. BACKGROUND Little is known about the measurement properties of Patient-Oriented Scoring Atopic Dermatitis (PO-SCORAD) in adults with AD. Even less is known about how PO-SCORAD performs compared to the Patient-Oriented Eczema Measure (POEM). OBJECTIVE To examine the measurement properties of PO-SCORAD and compare them with POEM. METHODS A prospective dermatology-practice based study of 291 AD patients (age 1872 years). RESULTS PO-SCORAD and POEM were moderately correlated with each other (Spearman rho=0.56); had weak-moderate correlations with Numeric Rating Scale (NRS) worst-itch and average-itch, Dermatology Life Quality Index (DLQI), ItchyQOL, Patient-Reported Outcomes Measurement Information System (PROMIS™) SleepDisturbance (SD) and Sleep-Related Impairment (SRI), Patient Health Questionnaire-9 (PHQ-9) and Eczema Area and Severity Index (EASI) (P less then 0.001). POEM had significantly stronger correlations with DLQI, ItchyQOL and EASI than did POSCORAD. PO-SCORAD and POEM had fair discriminant validity. Changes from baseline in PO-SCORAD and POEM were moderately correlated with each other, weakly to strongly correlated with NRS worst-itch and average-itch, DLQI, ItchyQOL, PROMIS SD, PROMIS SRI, PHQ9 and EASI and showed good test-retest reliability. There was no differential item functioning of items, or floor or ceiling effects for POSCORAD or POEM. The thresholds for meaningful change for PO-SCORAD and POEM were -15.5 and -5.0, respectively. Median completion time for PO-SCORAD and POEM was 3 and 1 minutes, respectively. CONCLUSION PO-SCORAD and POEM showed good construct and cross-cultural validity, reliability, and responsiveness in adults with AD, and were feasible for use in clinical trials and practice. However, POEM showed better measurement properties than PO-SCORAD. Prenatal caffeine exposure (PCE) induces developmental toxicity of multi-organ and susceptibility to multi-disease in offspring. However, the effects of PCE on osteoarthritis susceptibility in adult offspring and its intrauterine programming mechanism remain to be further investigated. Here, we found that PCE induced susceptibility to osteoarthritis in male adult offspring rats, which was related to the inhibited function of cartilage matrix synthesis from fetuses to adults. Meanwhile, PCE consistently downregulated the H3K9ac and expression levels of transforming growth factor β receptor 1 (TGFβR1), and then blocked TGFβ signaling pathway, which contributed to the suppressed cartilage matrix synthesis. NSC 125973 Moreover, the high level of corticosterone caused by PCE reduced the H3K9ac level on TGFβR1 promoter region through acting on glucocorticoids receptor (GR) and recruiting histone deacetylase 2 (HDAC2) into the nucleus of fetal chondrocytes. Taken together, PCE induced osteoarthritis susceptibility in male adult offspring rats, which was attributed to the low-functional programming of TGFβR1 induced by corticosterone via GR/HDAC2 signaling. Deoxynivalenol (DON), a toxic secondary metabolite produced by Fusarium species that mainly infests cereals such as wheat and corn, threatens human and livestock health. The present study describes the characterization of a novel bacterial strain, Pelagibacterium halotolerans ANSP101 which is capable of transforming DON to less-toxic product 3-keto-deoxynivalenol by the oxidation of the C3 hydroxyl group. Strain ANSP101 was isolated from a seawater sample from a depth of 55 m in Chinese Bohai sea. link2 The strain was identified as Pelagibacterium halotolerans by morphology characterization and 16S rDNA gene sequencing. The DON degrading activity of strain ANSP101 was predominantly attributed to the bacterial cell lysate. Besides, the cell lysate was sensitive to sodium dodecyl sulfate, heat, and proteinase K treatment, indicating that the intracellular proteins or enzymes are responsible for the DON degradation. The optimal temperature and pH for the maximal degradation of DON were 40 °C and pH 8.0 by the cell lysate. These results provide the potential use of P. halotolerans ANSP101 as a detoxification agent for DON decontamination in cereals and feed. BACKGROUND Postoperative pneumonia is the third most common complication in surgical patients. However, little is known regarding pneumonia after craniotomy, which is the most commonly performed surgery in the neurosurgery department. AIM To investigate the incidence of pneumonia and its association with the length of hospital stay, identify risk factors, and build a prediction model with nomogram. METHODS The study population was based on the American College of Surgeons National Surgical Quality Improvement Program 2005-2017. Both multivariate logistic regression models and linear regression models were employed. FINDINGS The overall incidence rate of postoperative pneumonia is 3.11% in a total of 57,201 surgeries. The risk factors include age >55, male, lower body mass index, diabetes, functional dependent, ventilator dependence, history of severe chronic obstructive pulmonary disease, hypertension, systemic sepsis, white blood cells >12,000, emergency case, American Society of Anesthesiologists class ≥3, general anesthesia, and total operation time >240 min. Ten featured factors are used in nomogram (C-statistic 0.803). Postoperative pneumonia was associated with extended hospital stay. Compared to other postoperative complications, pneumonia showed the second-highest impact on the extension of hospital stay (4.7 days). CONCLUSION This study identified several preoperative risk factors for postoperative pneumonia after craniotomy, novel factors including male, low BMI warrants further investigation. The novel nomogram could serve as a reliable tool for evaluating postoperative pneumonia risk preoperatively. Pyrazinamide is an active pharmaceutical compound for the treatment of tuberculosis. It possesses at least four crystalline polymorphs. link3 Polymorphism may cause solubility problems as the case of ritonavir has clearly demonstrated; however, polymorphs also provide opportunities to improve pharmaceutical formulations, in particular if the stable form is not very soluble. The four polymorphs of pyrazinamide constitute a rich system to investigate the usefulness of metastable forms and their stabilization. However, despite the existence of a number of papers on the polymorphism of pyrazinamide, well-defined equilibrium conditions between the polymorphs appear to be lacking. The main objectives of this paper are to establish the temperature and pressure equilibrium conditions between the so-called α and γ polymorphs of pyrazinamide, its liquid phase, and vapor phase and to determine the phase-change inequalities, such as enthalpies, entropies, and volume differences. The equilibrium temperature between α and γ was experimentally found at 392(1) K. Moreover, vapor pressures and solubilities of both phases have been determined, clearly indicating that form α is the more stable form at room temperature. High-pressure thermal analysis and the topological pressure-temperature phase diagram demonstrate that the γ form is stabilized by pressure and becomes stable at room temperature under a pressure of 260 MPa. Bacterial levan is a fructose homopolymer that offers great potential in biotechnological applications due to biocompatibility, biodegradability and non-toxicity. This biopolymer possesses diverse multifunctional features, which translates into a wide range of applicability, including in industry, consumer products, pharmaceuticals and biomedicine. Extensive research has identified great potential for its exploitation in human health. In addition, nanostructured systems have provided significant advances in the area of health, mainly with respect to disease diagnosis and treatment. While the functional properties of these natural polysaccharide-based polymers are desirable in these systems, research in this area has been limited to few natural polymers, such as chitosan, alginate and dextran, which obscures the true potential of levan in the production of nanostructured systems for biotechnological and medical applications. The present review considers the latest research in the field to focus on the use of levan as a promising biopolymer for the development of nanomaterials.
