Helicobacter pylori is a Gram-negative bacterium that is responsible for gastric and duodenal ulcers. H. pylori uses the unusual mqn pathway with aminofutalosine (AFL) as an intermediate for menaquinone biosynthesis. Previous reports indicate that hydrolysis of AFL by 5'-methylthioadenosine nucleosidase (HpMTAN) is the direct path for producing downstream metabolites in the mqn pathway. However, genomic analysis indicates jhp0252 is a candidate for encoding AFL deaminase (AFLDA), an activity for deaminating aminofutolasine. The product, futalosine, is not a known substrate for bacterial MTANs. Recombinant jhp0252 was expressed and characterized as an AFL deaminase (HpAFLDA). Its catalytic specificity includes AFL, 5'-methylthioadenosine, 5'-deoxyadenosine, adenosine, and S-adenosylhomocysteine. The kcat/Km value for AFL is 6.8 × 104 M-1 s-1, 26-fold greater than that for adenosine. 5'-Methylthiocoformycin (MTCF) is a slow-onset inhibitor for HpAFLDA and demonstrated inhibitory effects on H. pylori growth. Supplementation with futalosine partially restored H. pylori growth under MTCF treatment, suggesting AFL deamination is significant for cell growth. The crystal structures of apo-HpAFLDA and with MTCF at the catalytic sites show a catalytic site Zn2+ or Fe2+ as the water-activating group. With bound MTCF, the metal ion is 2.0 Å from the sp3 hydroxyl group of the transition state analogue. Metabolomics analysis revealed that HpAFLDA has intracellular activity and is inhibited by MTCF. check details The mqn pathway in H. pylori bifurcates at aminofutalosine with HpMTAN producing adenine and depurinated futalosine and HpAFLDA producing futalosine. Inhibition of cellular HpMTAN or HpAFLDA decreased the cellular content of menaquinone-6, supporting roles for both enzymes in the pathway.Prurigo nodularis (PN) is a chronic, recalcitrant inflammatory skin condition characterized by the presence of pruritic nodules. The exact pathogenesis of the disease is unknown, although immune and neural dysregulation are indicated in driving the itchscratch cycle. Specifically, interleukin-4 and interleukin-31 pathways have been recently implicated in transmission of the pruritic sensation. There are currently no US FDA-approved targeted therapies for the treatment of PN. This article aims to review our present understanding of the disease pathogenesis and treatments, with a focus on emerging therapeutics. Specifically, this article explores the developing use of monoclonal antibodies nemolizumab and dupilumab, opioid receptor modulation and cannabinoids as potential treatments for PN.
To evaluate the utility of extending the limbus-to-cannula distance to 6.0 mm during pars plana vitrectomy (PPV) for highly myopic eyes.
Four eyes with axial lengths exceeding 31.0 mm, that underwent 25-gauge PPV were retrospectively evaluated. Assuming that cannulas were inserted 3.5 and 6.0 mm from the corneal limbus, the distance from the cannula to the fovea (CF distance) was preoperatively evaluated using anterior segmental optical coherence tomography. Surgical complications were also investigated.
The CF distance was shortened by 1.22±0.05 mm and 1.22±0.09 mm on the temporal and nasal sides, respectively, by inserting the cannula at 3.5 to 6.0 mm from the corneal limbus. As per the preoperatively measured CF distance, one of the cannulas was inserted 6.0 mm from the corneal limbus in 3 eyes. Their cannulas were confirmed to be inserted at the pars plana, and no surgical complications associated with this technique were observed.
Extending the limbus-to-cannula distance to 6.0 mm during PPV could be one of the options to reach the posterior pole in highly myopic eyes. A preoperatively measured CF distance can be a clinical criterion in determining the cannula position.

The US military healthcare services provide the highest level of trusted medical care to its members and to the world population during catastrophic events. These services can be difficult, making moral and ethical situations commonplace. Moral distress results when actions are inconsistent with personal or professional beliefs, resulting in a loss of moral integrity. Moral distress research is well established in the civilian literature and results in poor outcomes and increased expenses. There is little research studying moral distress in military providers.
A clinical nurse specialist-led workshop was conducted with military and civilian experts. The expert panel reviewed the literature, examined instruments, and reviewed tool items for applicability to military healthcare providers.
The team determined the existing civilian moral distress tool was applicable to military providers. Twelve additional items were added to the modified tool. A tool testing plan was developed to test the tool in military critical care nurses on the last day of the workshop for the next phase of this project.
The civilian moral distress tool was adapted for a military version and will be tested in the next phase of the project.

The aim of this study was to explore the perceived quality of sleep and sleep disturbances in hospitalized patients.
A prospective descriptive, exploratory, cross-sectional study was conducted at a 172-bed community hospital in Northeast Ohio. A convenient sample of 100 hospitalized patients was recruited from medical/surgical, progressive care, and intensive care units.
Participants used the Richards-Campbell Sleep Questionnaire to report sleep. A quality of sleep assessment survey was used to collect information regarding 17 factors leading to decreased quality of sleep.
Mean sleep score was 47.92 for each question regarding sleep depth, latency, awakenings, time spent awake, and overall sleep quality. Pearson's correlation showed a significantly positive correlation between measure of noise and sleep score. Five environmental factors were identified as most disruptive to sleep pain, laboratory draws, staff, blood pressure checks, and intravenous alarms.
The positive correlation between sleeping well and higher noise levels is noteworthy. Raising awareness about the importance of sleep in the hospital setting and introducing interventions to promote a quiet environment and minimize sleep-disturbing factors may increase patient satisfaction scores and improve healing.

The aim of this study was to design a quantitative evaluation of the promotion plan for clinical nurse specialists in China.
The evaluation indexes were selected and established by inquiring 22 experts and using the analytic hierarchy process. The promotion plan was sent to 22 specialized nurses. The reference value was established by comparing the results from predictions made by experts and the self-evaluation of specialized nurses.
This study used the Delphi method and mixed qualitative and quantitative methods, which not only determined the entry of the promotion plan but also calculated its weight, and obtained the baseline score through a small range of empirical studies.
This promotion plan included basic promotion conditions, 5 primary indicators, 15 secondary indicators, and 61 tertiary indicators and was designed by experts who had a high degree of authority in this field. The self-evaluation results of 19 specialist nurses showed a reference value of 30 points per 3 years using the promotion plan. For clinical nursing managers, it is a management tool to evaluate specialist nurses, which can provide a basis for the promotion of specialist nurses.
The promotion plan for clinical nurse specialists in China formed by this research is quantifiable, scientific, and instructive.

The present study aimed to establish an index system for the performance evaluation of specialty nurses (SNs) in tertiary hospitals.
An objective index system for performance evaluation of SN has not yet been established in China.
A 2-round Delphi survey sought opinions from experts about the index system for SNs' performance evaluation in tertiary hospitals in China.
Delphi survey was used to inquire approximately 20 experts from the fields of nursing management, nursing education, and clinical nursing. We determined the weight coefficient of each index of performance evaluation based on the opinion. Finally, the index of the quality evaluation was established for SN.
A total of 20 experts from 10 provinces in China reached a consensus on the tertiary indexes of the assessment model. The indexes contained first-level (4), second-level (16), and third-level (24) indicators. The 4 aspects of the performance evaluation, including clinical specialist practice assessment, nursing research, education assessment, medical cooperation recognition, and personal comprehensive ability assessment, reached consensus.
Establishing the performance evaluation for SNs aided the SNs in achieving the best clinical practice after training. The performance evaluation still needed to be continuously improved.

Incivility contributes to employee dissatisfaction, turnover, patient errors, and a disrespectful culture. Turnover rates and employee exit interviews alerted hospital leaders to uncivil behaviors exhibited by staff. A clinical nurse specialist (CNS) team captured this as an opportunity to create a civility program to develop team cohesiveness and improve patient safety. The purpose of this process improvement project was to identify uncivil behaviors in a pediatric hospital.
Using the Plan-Do-Study-Act model, an interprofessional team led by CNSs collaborated on a program to assess, intervene, and evaluate a program to improve civility. A preprogram survey, the Negative Acts Questionnaire-Revised, was used to assess staff perceptions of their work environment. Staff attended an education program on ways to recognize and intervene in situations involving less than standard civil behavior. Classes included communication application in uncivil situations using scenarios paired with evidence-based practice articles. Unit leaders reset behavioral expectations learned from a leader-specific class on managing unproductive behaviors.
Staff completed a postprogram Negative Acts Questionnaire-Revised survey 6 months after conclusion of classes. Survey results indicated the civility program effected a reduction in frequency of negative behaviors indicating an overall positive shift in workplace civility.
The program provided staff with tools to recognize and intervene for improving civility, which impacted the overall work environment and patient safety.
