Descriptive study of COVID-19 vaccinations and infections within an NHS workforce.

BACKGROUND: Healthcare workers were a priority group for coronavirus disease 2019 (COVID-19) vaccination during the pandemic. Occupational exposure may account for some of the increased risk faced. AIMS: Describe COVID-19 vaccine uptake and infection rates in staff across a large NHS board in Scotland to better understand occupational risk during the pandemic. METHODS: Descriptive cross-sectional study. Demographic data were extracted on 5 August 2021 from 26 058 members of staff. COVID-19 vaccination status and positive polymerase chain reaction (PCR) results were extracted on two separate dates to describe the timeline of staff infections between March 2020 and January 2022. RESULTS: There was high uptake of all three vaccine doses across all demographic groups in hospital staff. PCR positivity decreased with increasing age and Scottish Index of Multiple Deprivation score. Staff and nosocomial COVID-19 infections followed peaks in community infection rates. CONCLUSIONS: NHS Lothian is a typical NHS workforce with good vaccine uptake. Beyond very early cases, there seems to be minimal evidence of occupational acquisition of COVID-19. The large number of nosocomial infections at the start of the pandemic may, in fact, reflect lack of community testing at this time. Despite protection from high vaccine coverage, job type and good Infection Prevention and Control practices, it seems that staff remain at high risk of catching the highly transmissible omicron variant from the community rather than work.

A systematic review of MR imaging as a tool for evaluating haemophilic arthropathy in children.

Our purposes were to determine: (i) whether there is direct evidence that currently available MRI techniques are accurate for early diagnosis of pathological findings in haemophilic arthropathy; (ii) whether there is an MRI scoring system that best correlates with clinical/radiological constructs for evaluation of haemophilic arthropathy; (iii) whether there is an MRI scoring system that best correlates with clinical/radiological constructs for evaluation of haemophilic arthropathy. Articles were screened using MEDLINE (n = 566), EMBASE (n = 201), and the Cochrane Library (n = 1). Two independent reviewers assessed articles for inclusion under the overarching purposes of the review by using the Standards for Reporting of Diagnostic Accuracy (STARD) tool, and the quality of the studies were graded using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. The electronic literature search retrieved 777 references (after duplicates were removed). A total of 32 studies were chosen for inclusion from the results of the search and review of bibliographical references. Using the STARD tool, seven studies were of excellent quality of reporting, and using the QUADAS-2 tool, 10 studies were judged to be of adequate quality. There is 'fair' evidence to recommend MRI as an accurate test for detecting evidence of haemophilic arthropathy and the use of second or third generation MRI scales for assessing haemophilic arthropathy. However, there is no evidence that screening of early intra-articular soft tissue bleed with MRI improves the functional status of joints over time.

Measurement of SARS-CoV-2 in air and on surfaces in Scottish hospitals.

BACKGROUND: There are still uncertainties in our knowledge of the amount of SARS-CoV-2 virus present in the environment - where it can be found, and potential exposure determinants - limiting our ability to effectively model and compare interventions for risk management. AIM: This study measured SARS-CoV-2 in three hospitals in Scotland on surfaces and in air, alongside ventilation and patient care activities. METHODS: Air sampling at 200 L/min for 20 min and surface sampling were performed in two wards designated to treat COVID-19-positive patients and two non-COVID-19 wards across three hospitals in November and December 2020. FINDINGS: Detectable samples of SARS-CoV-2 were found in COVID-19 treatment wards but not in non-COVID-19 wards. Most samples were below assay detection limits, but maximum concentrations reached 1.7×103 genomic copies/m3 in air and 1.9×104 copies per surface swab (3.2×102 copies/cm2 for surface loading). The estimated geometric mean air concentration (geometric standard deviation) across all hospitals was 0.41 (71) genomic copies/m3 and the corresponding values for surface contamination were 2.9 (29) copies/swab. SARS-CoV-2 RNA was found in non-patient areas (patient/visitor waiting rooms and personal protective equipment changing areas) associated with COVID-19 treatment wards. CONCLUSION: Non-patient areas of the hospital may pose risks for infection transmission and further attention should be paid to these areas. Standardization of sampling methods will improve understanding of levels of environmental contamination. The pandemic has demonstrated a need to review and act upon the challenges of older hospital buildings meeting current ventilation guidance.

Impaired hypoglycaemia awareness and employment in people with Type 1 diabetes.

BACKGROUND: Impaired awareness of hypoglycaemia (IAH) is common in adults with Type 1 diabetes mellitus (T1DM) and is a major risk factor for severe hypoglycaemia. Little is known about its effect on employment status. AIMS: To examine the effect that IAH has on the employment status or employability of people with T1DM. METHODS: A randomly selected cohort of adults of employment age with T1DM completed a questionnaire detailing the history of their diabetes, their occupational history (including job and industry type) and assessing both their hypoglycaemia awareness status and whether in their view their ability to obtain or retain employment had been adversely affected by having diabetes. RESULTS: A total of 252 patients participated, with the following characteristics: 135 males, mean HbA1c 8.5% [standard deviation (SD) 1.4], mean age 43.3 years (SD 13.2), mean duration of diabetes 21.3 years (SD 12.8) and prevalence of IAH 23.4%. The employment rate was comparable between those with preserved awareness (73%) and the IAH group (66%) (not significant). People with IAH were older (P < 0.05) and also more commonly felt that having diabetes affected their ability to work (P < 0.05). CONCLUSIONS: This study is the first to demonstrate that those with T1DM and IAH remain as economically active as those with normal awareness of hypoglycaemia, although subjects with IAH were significantly more likely to feel that having diabetes had adversely affected their capacity for employment.

Survival of Escherichia coli and Salmonella spp. after application of sewage sludge to a Pinus radiata forest.

AIMS: This study investigated the survival of Escherichia coli and Salmonella spp. in sewage sludge applied to young and old Pinus radiata forest in Spring and Autumn/Winter. METHODS AND RESULTS: Large numbers of E. coli were present in sludge applied to the forest blocks but Salmonella spp. numbers were low or nondetectable. In the mature stand in Spring, numbers of E. coli returned to back-ground after 3 weeks and die-off was significantly correlated with per cent solids of sludge. E. coli survived longer in mature and young stands in Autumn/Winter where numbers did not significantly decrease until weeks 5 and 13, respectively. Salmonella spp. was detectable in the mature stand until week 4 and in the young stand until week 11 in Autumn/Winter. CONCLUSIONS: Microbial die-off was related to desiccation of the sewage sludge, and was faster in warmer, drier conditions. SIGNIFICANCE AND IMPACT OF THE STUDY: In many countries, environmental and health risks associated with the application of sewage sludge to land are minimized by 'best management practice' guidelines, where risks are managed by restriction of public access to these sites. This study provides supporting evidence that withholding periods of greater than 6 months are sufficient to reduce microbial contaminants to background levels.

Change with time in patients' reactions to committal.

The influence of time on patients' reactions to involuntary committal is a variable seldom considered in reports. The reactions to committal of thirty-four subjects interviewed one week/one month/three months/six months post committal are reported. Generally committal was viewed neutrally. The major changes in attitudes related to knowledge of the fact of committal and of rights of appeal. The importance of these findings for the management of committed patients is stressed.

Adult children of alcoholics in treatment programs for anxiety disorders and substance abuse.

Studies of the first-degree relatives of patients with alcoholism and anxiety disorders have identified a significant overlap of these disorders. Forty percent of the patients in an outpatient anxiety disorder program were adult children of alcoholics (ACOA), a proportion similar to that found in the substance abuse program. The ACOAs in both programs were younger, had higher co-dependency scores and were younger when they had their first psychiatric contact than the controls. The adult children of alcoholics who had anxiety disorders were more likely to be female and their alcoholic parents were less likely to have had psychiatric antecedents to alcoholism. Aside from substance abuse, similarities in sociodemographic variables and the impact of the parents' alcoholism were noted, reinforcing the hypothesis that vulnerabilities to anxiety disorders and alcoholism overlap.

On evaluating patient satisfaction: methodological issues.

The survey of patient satisfaction with the mental health services provided is recommended but involves a methodological dilemma. Concerns include a definition problem, the delineation of a representative sample, the selection of a survey technique and the type of questions to be used. A literature review and the authors' own experience with the process are presented. The investigation of patient satisfaction while, as yet, limited in the critical information it can provide for the evaluation of services, will help pinpoint areas where the most patient dissatisfaction exists. The process can also be useful therapeutically, but patient satisfaction, although an important outcome measure, is not systematically related to other measures of treatment success. Methodological suggestions to improve the validity of the data gathered conclude the paper.

Patients' attitudes at the time of their commitment.

The discussion concerning who should be committed and by whom, has dominated the psychiatric literature for many years (1). More recently, the issue of whether committal allows merely for incarceration in the least restrictive alternative or whether it also entitles patients to be treated against their will, if necessary, has also received attention (2-5). As yet, few studies have attempted to define the characteristics of the committed population (6-11). Even fewer studies have attempted to define what patients themselves thought of their committal to hospital (12-15) and for the most part, have not obtained their opinions regarding the broader issues of committal that are being debated in the professional literature. This study seeks to elicit the opinions of patients in these matters.

Patients' reactions to their commitment.

The authors surveyed the reactions toward commitment of 61 respondents out of a sample of 100 patients who had been committed to hospital during a one year period. The patients reported little change in their life situation as a result of committal and most viewed committal quite neutrally. They generally felt uninformed of their rights and indicated little intent to appeal the commitments, but wished to be assured that their rights were being considered and protected. Most saw psychiatrists as the professional group best equipped to bring about a committal. The importance of consumer surveys in controversial areas such as this is underscored.

The adult children of alcoholics in a psychiatric population.

The issues confronting adult children of alcoholics (ACOA) are well publicized but their empirical basis remains limited. The screening of 250 consecutive psychiatric admissions to a general hospital revealed a significant prevalence of ACOAs across diagnoses. Compared to the other patients, the ACOA group was younger but with no other socioeconomic difference. The diagnoses of substance abuse and phobic disorders were more frequent. The group was psychiatrically hospitalized at an earlier age. The impact of an ACOA status varied with the parental biological relation and gender, and with the premorbid antecedents of parental alcoholism.
