Measurement of SARS-CoV-2 in air and on surfaces in Scottish hospitals. J Hosp Infect 2023; 133:1-7. [PMID: 36473553 PMCID: PMC9721166 DOI: 10.1016/j.jhin.2022.11.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Revised: 11/27/2022] [Accepted: 11/27/2022] [Indexed: 12/12/2022]
Abstract
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.

Abstract
BACKGROUND Vitamin B12, or cobalamin, is a nutrient that is vital for metabolic function. Absorption of ingested B12 is dependent on intrinsic factor, which is secreted by parietal cells within the stomach. Pernicious anemia is caused by an intrinsic factor deficiency or autoantibodies against intrinsic factor. The presence of parietal cell antibodies can destroy parietal cells, which can also lead to a deficiency in intrinsic factor. Both lead to megaloblastic anemia caused by vitamin B12 deficiency. The typical presentation of pernicious anemia includes fatigue, pale appearance, tingling sensation, depression, alterations to vision and smell, urinary incontinence, psychotic episodes, and weakness. The most effective treatment for pernicious anemia is intramuscular B12. CASE REPORT A 27-year-old woman with a history of vitiligo presented to the emergency department (ED) with bilateral lower extremity weakness, clumsiness, numbness, and tingling. Physical examination revealed ataxia, no sensation below her umbilicus, decreased strength, and hyperreflexia in both lower extremities. Complete blood count in the ED revealed low hemoglobin and hematocrit and elevated mean corpuscular volume, concerning for pernicious anemia. Further laboratory testing upon inpatient admission revealed a low vitamin B12 level and parietal cell antibodies in the blood. The patient's pernicious anemia was treated with intramuscular vitamin B12 injections, which led to near complete resolution of her symptoms. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Early suspicion and detection of pernicious anemia in the ED can prevent serious and permanent hematologic and neurologic damage and the development of other autoimmune disorders.

Abstract
Abstract
Introduction
Objectives of this retrospective study were to describe clinical presentations and mortality outcome of hospitalised patients with COVID-19 omicron variant within two acute district general hospitals and to evaluate demographic factors associated with these presentations and mortality.
Methods
Data was obtained over a month in 2021-22 from a retrospective survey of all patients hospitalised and detected to have SARS-COV-2 omicron variant infection. The trust serves a diverse multi-ethnic inner-city population. Data included socio-demographic details, vaccination status, admitting specialty and mortality outcome. Patients were sub-divided into three groups; Group 1 were admitted with ‘true’ COVID pneumonitis; Group 2 were found to have ‘incidental’ COVID on admission screening; Group 3 were negative for COVID on admission but developed COVID >7days after admission.
Results
Of 553 patients, only 24.1%[133/553] were in Group 1; 322[58.2%] in Group 2; 98[17.7%] in Group 3. Patients with Group 1 and Group 3 were significantly older than those in Group 2 (p<0.001). 30% patients from BAME ethnicity had COVID pneumonitis compared to 19% from white ethnicity[p=0.002]. 20% patients were admitted within non-medical specialties i.e. surgical specialties, paediatrics and obstetrics. Of 36 requiring critical care, only 21 were in Group 1; 20/21[95%] of these were unvaccinated; 7/21 who died were all unvaccinated[100%]. This study showed that common COVID presentations included delirium, falls (and fractures), seizures, COPD, and antenatal problems. 13.7%[76/553] patients died; only 21 were in Group 1[27.6%]. Only 26 deaths were directly attributable to COVID; 4.7%[26/553] of all patients.
Discussion
This large multi-ethnic study has described clinical presentations and mortality of hospitalised patients with omicron. It has determined socio-demographic factors associated with these presentations including ethnicity and vaccination rates. The study useful information for future COVID studies examining outcomes and presentations of omicron and future COVID variants.

Abstract
Abstract
Introduction
Demographic evaluation of urgent community response teams [UCR] is important to ensure equity of access and clinical outcomes for patients from all socio-demographic groups using such services. This retrospective descriptive study aimed to evaluate demographic and mortality differences between patients referred to UCR in terms of those managed in the community [Group1] versus those subsequently hospitalised [Group2].
Methods
Data was obtained over a 12-month period [2021-2022] for all new patients referred to a 7-day consultant-led UCR that serves a multi-ethnic, inner-city population. Data included demographic details, source of referral, urgency of referral and mortality within 60 days.
Results
Of 995 patients, 75.6%[n=752] were in Group 1; 24.4%[243] were in Group 2. The two groups were comparable in terms of age [mean(SD): 80.1(12.6) vs 80.0(11.4), p=ns] and gender [males:39.4% vs 42.4%,p=ns]. There were similar proportion of Black and minority ethnic patients within the two groups [21.0% (158) vs 24.7% (60), p=ns]. Source of referral were comparable between the two groups[p=ns]; overall, 67.7%[674] were from GP practices, 5.6%[56] Community Practitioners, 4.7%[47] NHS111, 2.7%[27] Ambulance, 32%[32] Palliative care, 5.9%[59] Emergency department, 10.1%[100] post-hospitalisation. Compared to Group 1 [46.9% (353)], significantly more patients in Group 2 were referred for urgent assessment within 2 hours [65.4% (159), p<0.001]. More patients died in Group2 within 60 days [22.2% (54) vs 11.3% (85), p<0.001].
Discussion
This large survey has described age, gender and ethnic similarities between the two groups, demonstrating equity of provision irrespective of protected characteristics. As might be clinically expected, patients referred for hospitalisation were assessed more urgently and had higher mortality rates compared to those managed in the community. This study provides valuable information for clinicians and researchers of similar UCR services in future.

Abstract
Abstract
Introduction
Diagnosis of Transient Ischaemic Attack [TIA] is important to minimise risk of future strokes. This retrospective descriptive study aimed to describe frequency of alternative diagnoses in a busy inner-city neurovascular clinic and evaluate processes of assessment and investigations of ‘true’ TIA patients.
Methods
Data was obtained over a 2-year period [2019-2020] for all new patients assessed in a busy consultant-provided daily week-day neurovascular service that serves a million multi-ethnic, population. Data collected included socio-demographic details, final clinical diagnoses, and process measures including speed of assessment and rate of neurological and cardiological investigations.
Results
Of 1764 patients, 39.3%[694] were diagnosed as TIA; 60.7%[1070] had 40 distinct differential diagnoses. Top ten diagnoses included migraine including ocular migraine [9.5%], Syncope [5.5%], Local Eye conditions (non-neurological)[5.3%], non-cervical radiculopathy [4.0%], Benign Paroxysmal Positional Vertigo [4.0%], Previous/Incidental Stroke [3.7%], Transient Global Amnesia [2.4%], Orthostatic Hypotension [1.8%], Non-migraine Headache syndromes [1.6%], Cervical Neuropathy [1.3%]. 10.9%[193] had no organic pathological diagnosis. For 694 TIA patients, 100% had neuroimaging [CT/MRI] and 98% had carotid dopplers on or before day of clinic. Non-urgent cardiovascular investigations performed included echocardiogram [83%], Holter monitoring [75%] and bubble echocardiogram [5%].
Discussion
This large survey has described the frequency of TIA and alternative diagnoses in a dedicated neurovascular service. The study highlights the importance of accurate diagnosis of TIA by experienced clinicians for appropriate secondary prevention. We also described the efficiency, and speed of assessment and proportion of investigations undertaken in these patients. This study provides valuable information to clinicians, researchers and commissioners of stroke services in future.

Abstract
Introduction
Diagnosis of Transient Ischaemic Attack [TIA] is important to minimise risk of future strokes. This retrospective descriptive study aimed to evaluate socio-demographic and risk factor differences between TIA and TIA ‘mimics’ in patients presenting to an inner-city neurovascular clinic.
Methods
Data was obtained over a 2-year period [2019-2020] for all new patients assessed in a consultant-provided daily week-day neurovascular service that serves a million multi-ethnic, population. Data collected included socio-demographic details, clinical risk factors, source of referral and final clinical diagnoses.
Results
Of 1764 patients, 39% [694] were diagnosed as TIA; 61% [1070] were TIA mimics with 40 distinct differential diagnoses. Compared to TIA mimics, TIA patients were older [mean(SD): 69.3(13.8) vs 59.7(16.1),p<0.001]; higher prevalence of TIA mimics in females vs males [66% vs 54%; p<0.001]. There were proportionately more patients with TIA mimics from Black and minority ethnic groups (401/610:66%) compared whites (669/1154:58%)[p=0.034]. Compared to TIA mimics, TIA patients had higher prevalence of hypertension [56% vs 40%,p<0.001], Diabetes [22% vs 14%,p<0.001], Atrial Fibrillation [10% vs 4%,p<0.001], Chronic Heart Disease [18% vs 9%,p<0.001] and moderate to severe carotid stenosis [5% vs 0.4%,p<0.001]. Prevalence of other risk factors in TIA patients included Patent Foramen Ovale [1.4%], Cardiolipin Antibodies [3.2%], and Thrombophilia [2.3%]. 14% of TIA patients had no identifiable risk factors.
Discussion
This large survey has described socio-demographic [age, gender and ethnicity] differences and prevalence of risk factors between TIA patients and TIA mimics. These differences may be useful in terms accurate diagnosis of TIA by experienced clinicians. This study provides valuable information for clinicians and researchers of stroke services in future.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Streptococcus mutans a key pathogen, produces biofilm, acids and extracellular polysaccharides in the oral cavity; which leads to the development of dental caries. Control of these pathogenic markers can prevent dental caries. Uvaria chamae P. Beauv. is a medicinal plant traditionally used for many ailments including oral infections. Root, leaves and bark extracts has proven antibacterial activity including activity against caries causing S. mutans. However, its effect on the virulence properties of S. mutans, responsible for the development of dental caries, has not been studied. AIM OF THE STUDY This study investigated the phytochemical constituents, anti-S. mutans, anti-adherence and anti-acidogenic activity of U. chamae root extract. MATERIALS AND METHODS Extracts were prepared and phytochemical analysis was performed. Minimum inhibitory concentrations (MIC) were determined, and MIC and sub-MIC concentrations of the best solvent were selected for their effect on the virulence factors of S. mutans. The results were analysed using one-way ANOVA and Wilcoxon Rank Sum Tests. RESULTS The dichloromethane extract, with proanthocyanidin as a major chemical constituent, produced an MIC of 0.02 mg/ml. At 6 h, exposure to 0.005, 0.01, and 0.02 mg/ml extract significantly reduced S. mutans adherence by 39, 59, and 77% respectively (p < 0.05). Uvaria chamae also significantly inhibited acid production in S. mutans at 10, 12, 14 and 16 h (p < 0.05). At ½ MIC, the plant extract caused remarkable downregulation of the virulence genes responsible for the adherence, biofilm formation, extracellular polysaccharide synthesis and acid production. CONCLUSIONS This suggests that U. chamae extract may potentially be used to inhibit the proliferation of S. mutans and silencing the expression of pathology-related genes, which will prevent the development of dental caries.

Abstract
OBJECTIVES To better understand the explanatory-pragmatic distinction in the design and interpretation of randomized controlled trials (RCTs). METHODS We review the explanatory-pragmatic distinction in clinical trial design. We use the PRECIS-2 tool to evaluate the trial design of selected RCTs on percutaneous vertebroplasty for osteoporotic vertebral compression fractures. We discuss difficulties in the selection of criteria and in the construction of PRECIS diagrams. We also examine how inconsistency in the selection of various items of trial design can cause confusion in the interpretation of results. RESULTS The selection of criteria and the scoring of multiple PRECIS domains were subjective and thus debatable. The pragmascope patterns of various vertebroplasty trials were heterogeneous. Many trials had both pragmatic and explanatory components. Some placebo-controlled trial goals seem to have been explanatory, but their design actually included enough pragmatic items such that the meaning of negative trial results remains ambiguous. CONCLUSION The results of a trial cannot be interpreted without understanding the various design choices made along the explanatory-pragmatic spectrum.

Abstract
Chronic inflammatory diseases are highly comorbid with anxiety in humans. The extent to which chronic inflammation is responsible for this relationship remains to be determined. We therefore tested the hypothesis that prolonged, but not brief, gut inflammation is sufficient to evoke anxiety-related behaviours in mice. We used the discriminative fear to context conditioning paradigm to assess fear generalization, which is a prominent feature of anxiety disorders. Gut inflammation was induced by exposure to dextran sodium sulfate (DSS) in the drinking water, a well-established rodent model of ulcerative colitis evoking prolonged inflammation. Neither acute (1 × 5 day cycle) nor chronic (3 × 5 day cycles) exposure to DSS affected fear responses when tested shortly after conditioning. Mice in all groups generated more fear responses (freezing) in a chamber previously paired with mild shock, as compared to a chamber with no pairing. This suggests DSS exposure had no effect on acquisition or expression of conditioned fear. Acute and control animals showed this same contextual control of freezing when tested 9 days later. In contrast, at this remote time point, the chronically treated animals exhibited increased freezing in the unpaired chamber such that freezing was equivalent in both contexts. These animals, however, showed intact preference for the unpaired chamber when allowed to freely move between chambers. These data suggest that some mnemonic process engaged after training, such as memory consolidation, is affected by past chronic inflammation so as to generalize negative associations and engage fearful responding in inappropriate contexts, despite intact knowledge that the chambers have different affective associations sufficient for place preference.
