ABSTRACT
Background There have been growing concerns about the wellbeing of staff in inpatient mental health settings, with studies suggesting that they have higher burnout and greater work-related stress levels than staff in other healthcare sectors. When addressing staff wellbeing, psychological safety can be a useful concept. However, there is no measure of psychological safety that is suitable for use in inpatient mental health settings. Edmondson (1999) is the most commonly used measure of psychological safety, but it was designed for use in general physical healthcare settings. As inpatient mental health settings are unique environments, transferability of knowledge from physical to mental healthcare settings cannot be assumed. Methods We sought to develop questionnaire items that capture psychological safety amongst healthcare staff working in acute inpatient mental healthcare settings. We used the nominal group technique, a consensus method involving rounds of discussion, idea generation and item rating/ranking to identify priorities. Twenty-eight stakeholders participated, including 4 who had lived experience of mental health problems, 11 academics and 18 healthcare professionals (eight participants identified with more than one category). The study involved a workshop with three parts: 1) an overview of current research and limitations of the Edmondson (1999) measure as outlined above, 2) discussion on what items should be retained from the Edmondson (1999) measure, and 3) discussion on what items should be added to the Edmondson (1999) measure. Results Twenty-one items were generated and retained to capture psychological safety in inpatient mental health settings. These measure professionals' sense of being valued by their team and organisation, feeling supported at work, feeling physically safe and protected from physical harm, and knowing they can raise concerns about risk and safety. Conclusion This is the first study to generate questionnaire items suitable for measuring staff psychological safety in mental health settings. These have been generated via a consensus method to ensure stakeholder's views are reflected. Further research is needed to evaluate factor structure, internal reliability and convergent validity.
ABSTRACT
Bacteria are preyed upon by diverse microbial predators, including bacteriophage and predatory bacteria, such as Bdellovibrio bacteriovorus While bacteriophage are used as antimicrobial therapies in Eastern Europe and are being applied for compassionate use in the United States, predatory bacteria are only just beginning to reveal their potential therapeutic uses. However, predation by either predator type can falter due to different adaptations arising in the prey bacteria. When testing poultry farm wastewater for novel Bdellovibrio isolates on Escherichia coli prey lawns, individual composite plaques were isolated containing both an RTP (rosette-tailed-phage)-like-phage and a B. bacteriovorus strain and showing central prey lysis and halos of extra lysis. Combining the purified phage with a lab strain of B. bacteriovorus HD100 recapitulated haloed plaques and increased killing of the E. coli prey in liquid culture, showing an effective side-by-side action of these predators compared to their actions alone. Using approximate Bayesian computation to select the best fitting from a variety of different mathematical models demonstrated that the experimental data could be explained only by assuming the existence of three prey phenotypes: (i) sensitive to both predators, (ii) genetically resistant to phage only, and (iii) plastic resistant to B. bacteriovorus only. Although each predator reduces prey availability for the other, high phage numbers did not abolish B. bacteriovorus predation, so both predators are competent to coexist and are causing different selective pressures on the bacterial surface while, in tandem, controlling prey bacterial numbers efficiently. This suggests that combinatorial predator therapy could overcome problems of phage resistance.IMPORTANCE With increasing levels of antibiotic resistance, the development of alternative antibacterial therapies is urgently needed. Two potential alternatives are bacteriophage and predatory bacteria. Bacteriophage therapy has been used, but prey/host specificity and the rapid acquisition of bacterial resistance to bacteriophage are practical considerations. Predatory bacteria are of interest due to their broad Gram-negative bacterial prey range and the lack of simple resistance mechanisms. Here, a bacteriophage and a strain of Bdellovibrio bacteriovorus, preyed side by side on a population of E. coli, causing a significantly greater decrease in prey numbers than either alone. Such combinatorial predator therapy may have greater potential than individual predators since prey surface changes selected for by each predator do not protect prey against the other predator.

Well-differentiated neuroendocrine tumors (NET) of the ileum are generally slow-growing tumors with metastatic potential that may cause systemic symptoms from the secretion of serotonin, cortisol, and other biologically active substances. Likewise, steroid cell tumors of the ovary are slow-growing tumors that cause systemic symptoms from the functional production of androgens, estrogens, and other hormones. To the best of our knowledge, synchronous ileal NET and ovarian steroid cell tumors have not been previously reported in the English literature. We present a case of a 59-yr-old woman with 2 primary tumors that were found incidentally: a Stage III (T2N1M0) 1.6 cm well-differentiated NET (NET G2) of the terminal ileum with metastasis to a mesenteric lymph node and a 2.4 cm steroid cell tumor of the left ovary. The patient had suffered from hyperandrogenism for several years before diagnosis of an ovarian steroid cell tumor, but had no symptoms attributable to the NET. From review of the literature, this is the first case description of these 2 primaries arising in the same individual.

BACKGROUND: Clinical functional assessments of balance often lack specificity and sensitivity in discriminating and predicting falls among community-dwelling older adults. AIMS: We determined the feasibility of using a smart-device application measuring balance to discriminate fall status among older adults. We also evaluated differences between smart-device balance measurements when secured with or without a harness. METHODS: A cross-sectional study design to determine the ability of the Sway Balance smart-device application (SWAY) to discriminate older adults based on fall history. The Berg Balance Scale (BBS) and Activities-Specific Balance Confidence Scale (ABC) were used as comparative, clinically based assessments. Community-dwelling older adults with (n = 25) and without (n = 32) a history of fall(s) participated. Multivariate analysis of variance was used to determine differences among assessments based on fall history. Logistic regression models determined the ability of each assessment to discriminate fall history. RESULTS: Older adults with and without a history of falls were not significantly different on SWAY (P = 0.92) but were different on BBS (P = 0.01), and ABC (P < 0.001). Similarly, SWAY did not discriminate fall history (P = 0.92), while BBS and ABC both discriminated fall history (P < 0.01). Paired t tests between SWAY scores with and without a harness indicated no differences (P ≥ 0.05). CONCLUSION: Among the older adults studied, the BBS and ABC measures discriminated groups defined by fall history, while the SWAY smart-device balance application did not. Modifications to the application may improve the discriminating ability of the measure in the recognition of fall status in older adults.

BACKGROUND: The notion of person-centered care has been important in investigating relationships between people with dementia and paid carers, and measures are available to assess this. It has been suggested that person-centered care may be a useful construct to apply to understand family-care relationships. However, no measures of person-centered care in this context exist. The study aimed to develop an observational measure of person-centered care for this purpose. METHOD: First, a coding system incorporating a range of behaviors that could be considered person-centered or non-person-centered was constructed. Examples included a code relating to whether the person with dementia was involved in planning a task, and a code relating to how the spouse responded to confusion/distress. Second, 11 couples, where one partner had a dementia, were recruited and videotaped cooperating on an everyday task. The system was applied to the care-giving spouse's behaviors, labeling examples of behavior as person-centered or non-person-centered. The final step involved assessing the inter-rater reliability of the system. RESULTS: The system captured nine categories of behavior, which were each divided into person-centered and non-person-centered types. The system had good reliability (Cohen's κ coefficients were: 0.65 for category and whether behaviors needed to be placed in a category; 0.81 for category excluding the decision about whether behaviors needed to be placed in a category; and 0.79 in relation to whether behaviors were person-centered or non-person-centered.). CONCLUSIONS: Although the small sample size limits the implications of the results, the system is a promising quantitative measure of spousal person-centered care.

INTRODUCTION: At present, pregnant women in the U.S. are recommended to receive tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) and influenza vaccines. This study assessed maternal coverage of these 2 vaccinations. METHODS: Data for this retrospective cohort study were extracted from 2 large administrative claims databases, the MarketScan Commercial and Multi-State Medicaid Databases, for 2009-2017 and analyzed in 2018. Women aged 15-44 years on the date of pregnancy end were included. Pregnancies with gestational age of less than 23 weeks were excluded from the Tdap vaccination endpoint owing to the optimal recommended gestational age for Tdap vaccination. Multivariable logistic regression models identified predictors of vaccination. RESULTS: The Tdap vaccination subpopulation included 1,421,452 Commercial and 523,635 Medicaid pregnancies; the influenza vaccination subpopulation included 1,862,705 Commercial and 628,079 Medicaid pregnancies. There were marked increases in vaccination coverage from 2010 to 2017: from 1.0% to 56.3% (Commercial) and from 0.5% to 31.4% (Medicaid) for Tdap, and from 14.7% to 31.3% (Commercial) and from 9.7% to 17.5% (Medicaid) for influenza. The likelihood of Tdap/influenza vaccination increased significantly with receipt of the other vaccine and more pregnancy-related healthcare visits. CONCLUSIONS: Although maternal Tdap and influenza vaccination coverage increased substantially from 2010 to 2017 among large, geographically diverse U.S. cohorts, coverage remained suboptimal, potentially putting newborns at risk of pertussis and influenza. Strategies to increase maternal vaccination coverage could target women identified to have a reduced likelihood of vaccination: those who are younger, black, residing in rural areas, with multiple gestation, and a prepregnancy inpatient admission.

Lymphedema is a chronic, progressive disease with no curative treatment. Breast cancer therapy is the most common cause of secondary lymphedema in the developed world. Treatment includes nonsurgical and surgical strategies. Conservative measures are reserved for subclinical lymphedema. Surgical options are divided into physiologic (to restore function) and reductive (to remove diseased tissue). Early stage disease is managed with physiologic procedures. Reductive treatment is reserved for moderate to severe staged disease owing to high morbidity. Surgical options effectively decrease edema and improve quality of life. However, further research is necessary to best establish management of lymphedema.

Cases of Vibrio infections in the United States have tripled from 1996 to 2009 and these infections are most often associated with the consumption of seafood, particularly oysters (Crassostrea virginica). Information is needed on how to reduce numbers of Vibrio parahaemolyticus and Vibrio vulnificus in bi-valve molluscan shellfish (for example, oysters). The purpose of this study was to evaluate the effectiveness of high salinity relaying or treatment in recirculating aquaculture systems (RASs) as methods to reduce the abundance of V. parahaemolyticus and V. vulnificus in oysters. For relaying field trials, oysters were collected from approved harvest waters, temperature abused outside under a tarp for 4 h, and then transferred to high (29 to 33 ppt.) and moderate (12 to 19 ppt.) salinities. For RAS treatment trial, oysters were transferred to 32 to 34 ppt. salinity at 15 °C. After 7, 14, 21, and in some instances 28 d, oysters were collected and analyzed for V. parahaemolyticus and V. vulnificus levels using multiplex real-time PCR. Initial levels of V. parahaemolyticus and V. vulnificus ranged from 3.70 to 5.64 log10 MPN/g, and were reduced by 2 to 5 logs after 21 to 28 d in high salinity water (29 to 34 ppt.). Oyster mortalities averaged 4% or less, and did not exceed 7%. Relaying of oysters to high salinity field sites or transfer to high salinity RAS tanks was more effective in reducing V. vulnificus compared with V. parahaemolyticus. These results suggest that high salinity relaying of oysters is more effective in reducing V. vulnificus than V. parahaemolyticus in the oyster species used in this study.
