Abstract
PURPOSE Screening for frailty in people admitted with emergency surgical pathology can initiate timely referrals to enhanced perioperative services such as intensive care and geriatric medicine. However, there has been little research exploring surgical healthcare professionals' opinions to frailty assessment, or accuracy in identification. This study aimed to assess the knowledge, behaviour, and attitudes of healthcare professionals to frailty assessment in emergency surgical admissions. METHODS We designed a cross-sectional multicentre study developed by a multiprofessional team of surgeons, geriatricians, and supported by patients. A semi-structured survey examined attitudes and behaviours. Knowledge was assessed by comparing respondents' accuracy in scoring twenty-two surgical case vignettes using the Clinical Frailty Scale. RESULTS Eleven hospitals across England, Wales, and Scotland participated. Two hundred and eleven clinicians responded-20.4% junior doctors, 43.6% middle grade doctors, 24.2% senior doctors, 11.4% nurses and physician associates. Respondents strongly supported perioperative frailty assessment. Most were already assessing for frailty, although frequently not using a standardised tool. There was a strong call for more frailty education. Participants scored 2175 vignettes with 55.4% accurately meeting the gold standard; accuracy improved to 87.3% when categorised into "not frail/mildly frail/severely frail" and 94% when dichotomised to "not frail/frail". CONCLUSION Frailty assessment is well supported by healthcare professionals working in surgery. However, standardised tools are not routinely being used, and only half of respondents could accurately identify frailty. Better education around frailty assessment is needed for healthcare professionals working in surgery to improve perioperative pathway for people living with frailty.

The association between frailty and survival in patients with pleural disease: a retrospective cohort study. BMC Pulm Med 2024; 24:180. [PMID: 38627673 PMCID: PMC11020337 DOI: 10.1186/s12890-024-02981-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 03/25/2024] [Indexed: 04/19/2024] Open
Abstract
BACKGROUND There are currently no data on the relationship between frailty and mortality in pleural disease. Understanding the relationship between frailty and outcomes is increasingly important for clinicians to guide decisions regarding investigation and management. This study aims to explore the relationship between all-cause mortality and frailty status in patients with pleural disease. METHODS In this retrospective analysis of a prospectively collected observational cohort study, outpatients presenting to the pleural service at a tertiary centre in Bristol, UK with a radiologically confirmed, undiagnosed pleural effusion underwent comprehensive assessment and were assigned a final diagnosis at 12 months. The modified frailty index (mFI) was calculated and participants classified as frail (mFI ≥ 0.4) or not frail (mFI ≤ 0.2). RESULTS 676 participants were included from 3rd March 2008 to 29th December 2020. The median time to mortality was 490 days (IQR 161-1595). A positive association was found between 12-month mortality and frailty (aHR = 1.72, 95% CI 1.02-2.76, p = 0.025) and age ≥ 80 (aHR = 1.80, 95% CI 1.24-2.62, p = 0.002). Subgroup analyses found a stronger association between 12-month mortality and frailty in benign disease (aHR = 4.36, 95% CI 2.17-8.77, p < 0.0001) than in all pleural disease. Malignancy irrespective of frailty status was associated with an increase in all-cause mortality (aHR = 10.40, 95% CI 6.01-18.01, p < 0.0001). CONCLUSION This is the first study evaluating the relationship between frailty and outcomes in pleural disease. Our data demonstrates a strong association between frailty and 12-month mortality in this cohort. A malignant diagnosis is an independent predictor of 12-month mortality, irrespective of frailty status. Frailty was also strongly associated with 12-month mortality in patients with a benign underlying cause for their pleural disease. This has clinical relevance for pleural physicians; evaluating patients' frailty status and its impact on mortality can guide clinicians in assessing suitability for invasive investigation and management. TRIAL REGISTRATION This study is registered with the Health Research Authority (REC reference 08/H0102/11) and the NIHR Portfolio (Study ID 8960).

Abstract
Wastewater-based epidemiology has increasingly demonstrated its importance in addressing public health threats. The COVID-19 pandemic brought forth funding for public health agencies to conduct wastewater-based epidemiology. Using a team with diverse skills, a local health department utilized this funding to regularly monitor SARS-CoV-2 in wastewater on university campuses, a K-12 campus, an inpatient psychiatric facility, and a long-term care facility. Between September 2021 and May 2022, more than 760 wastewater samples were collected of which 102 (13.4%) were above a predetermined threshold. When sites exceeded that threshold, local health department staff provided testing resources. Wastewater-based epidemiology is a useful surveillance program that can be effectively conducted by local health departments when provided with funding and a skilled workforce.

A cluster randomised, 16-week, parallel-group multicentre trial to compare the effectiveness of a digital school-based cognitive behavioural resilience/wellbeing-building intervention targeting emotional and behavioural problems in vulnerable Year 4 primary school children in whole classes, to the usual school curriculum: a study protocol to the "CUES for Schools" trial. Trials 2023; 24:253. [PMID: 37013581 PMCID: PMC10071738 DOI: 10.1186/s13063-023-07267-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Accepted: 03/20/2023] [Indexed: 04/05/2023] Open
Abstract
BACKGROUND Around 10% of school-aged children experience mental health difficulties. Many more are 'vulnerable': experiencing emotional and/or behavioural problems reaching clinical levels, and thus at greatest risk of future mental illness. The trial aim is to evaluate the effectiveness of the CUES for schools programme in reducing emotional and behavioural problems in vulnerable children. METHODS The "CUES for Schools" study is a multicentre cluster randomised controlled trial in primary schools in south east England. Schools will be randomised to receive the usual school curriculum, or the CUES programme (1:1). We aim to enrol 74 schools (5550 children including 2220 vulnerable children). CUES is a whole-class teacher-facilitated interactive digital cognitive-behavioural intervention, delivered as 24 short (20-min) modules over 12 weeks, targeting emotional/behavioural regulation skills. Children self-report emotional/behavioural problems at baseline, 8, and 16 weeks, and wellbeing and cognitive vulnerability at 0 and 16 weeks. Adverse events are assessed at 8 and 16 weeks. Teachers rate classroom behaviour at baseline and 16 weeks. School senior leadership teams and individual teachers consent to involvement in the study; parents can opt their child out of CUES sessions, assessments, or research. Children can similarly opt out and assent to research participation. The primary objective of this trial is to evaluate the effectiveness of CUES for schools compared to the usual school curriculum in improving emotional/behavioural problems for vulnerable Year 4 (8-9 years old) children at 16 weeks post-randomisation, as measured using a standardised questionnaire designed for primary schools. The secondary objective is to investigate the impact of the CUES for schools programme on both vulnerable and non-vulnerable children on wellbeing and teacher-rated classroom behaviour. DISCUSSION The study will show whether CUES for schools is more effective than the usual curriculum in reducing emotional and behavioural problems in vulnerable Year 4 children, and thus reducing the risk of mental health difficulties in later adolescent and adult life. As a digital, teacher-facilitated intervention, CUES for schools can be readily implemented, at minimal cost. If effective, CUES for schools therefore has the potential to reduce the impact of emotional/behavioural difficulties on children's learning, behaviour, and relationships and the burden of future mental health morbidity.

Abstract
Emergency laparotomy procedures have high rates of postoperative mortality and morbidity in older patient. Sarcopenia is associated with poor postoperative outcomes in elective surgeries and there is growing evidence for its use as a risk predictor in the emergency setting. The study aimed to evaluate the effect of sarcopenia on postoperative mortality and morbidity following emergency laparotomy. Five electronic databases were systematically searched (MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and Web of Science) from conception until the 14th February 2022. All prospective cohort studies were included. Risk of bias was assessed with the Newcastle-Ottawa score. Pooled meta-analyses were estimated using the Mantel-Haenszel and inverse-generic variance method for mortality and morbidity outcomes. Eleven retrospective cohort studies were included, of which ten were included in the meta-analysis comprising of 3492 patients (1027 sarcopenic, 2465 non-sarcopenic). The study level incidence of sarcopenia ranged from 24.6 to 50.3% with a median rate of 25.1%. Sarcopenia was associated with increased 30-day mortality (OR 2.36, 95% CI, 1.66, 3.37, I2 = 43%), 90-day mortality (OR 2.51, 95% CI, 1.79, 3.52, I2 = 0%), and length of hospital stay (in days) (MD 1.18, 95% CI, 0.42, 1.94, I2 = 0%, P=0.002), but not incidence of postoperative major complications (OR 1.49, 95% CI, 0.86, 2.56, I2 = 70%, P = 0.15). Sarcopenia predicts poor outcomes following emergency laparotomy. We suggest assessment of sarcopenia should be incorporated into acute surgical assessment to identify high risk patients and inform clinical decision-making prior to an emergency laparotomy.

Validity assessment of Michigan's proposed qPCR threshold value for rapid water-quality monitoring of E. coli contamination. WATER RESEARCH 2022; 226:119235. [PMID: 36257159 DOI: 10.1016/j.watres.2022.119235] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 10/01/2022] [Accepted: 10/09/2022] [Indexed: 06/16/2023]
Abstract
Michigan's water-quality standards specify that E. coli concentrations at bathing beaches must not exceed 300 E. coli per 100 mL, as determined by the geometric mean of culture-based concentrations in three or more representative samples from a given beach on a given day. Culture-based analysis requires 18-24 h to complete, so results are not available on the day of sampling. This one-day delay is problematic because results cannot be used to prevent recreation at beaches that are unsafe on the sampling day, nor do they reliably indicate whether recreation should be prevented the next day, due to high between-day variability in E. coli concentrations demonstrated by previous studies. By contrast, qPCR-based E. coli concentrations can be obtained in 3-4 h, making same-day beach notification decisions possible. Michigan has proposed a qPCR threshold value (qTV) for E. coli of 1.863 log10 gene copies per reaction as a potential equivalent value to the state standard, based on statistical analysis of a set of state-wide training data from 2016 to 2018. The main purpose of the present study is to assess the validity of the proposed qTV by determining whether the implied qPCR-based beach notification decisions agree well with culture-based decisions on two sets of test data from 2016-2018 (6,564 samples) and 2019-2020 (3,205 samples), and whether performance of the proposed qTV is similar on the test and training data. The results show that performance of Michigan's proposed qTV on both sets of test data was consistently good (e.g., 95% agreement with culture-based beach notification decisions during 2019-2020) and was as good as or better than its performance on the training data set. The false-negative rate for the proposed qTV was 25-29%, meaning that beach notification decisions based on the qTV would be expected to permit recreation on the day of sampling in 25-29% of cases where the beach exceeds the state standard for FIB contamination. This false-negative rate is higher than one would hope to see but is well below the corresponding error rate for culture-based decisions, which permit recreation at beaches that exceed the state standard on the day of sampling in 100% of cases because of the one-day delay in obtaining results. The key advantage of qPCR-based analysis is that it permits a large percentage (71-75%) of unsafe beaches to be identified in time to prevent recreation on the day of sampling.

Abstract
Background Extragenital gonococcal infections are common among men who have sex with men (MSM); however, data comparing antimicrobial susceptibilities of urogenital and extragenital Neisseria gonorrhoeae isolates are limited. We investigated differences in gonococcal antimicrobial susceptibility by anatomic site among cisgender MSM using specimens collected through CDC’s enhanced Gonococcal Isolate Surveillance Project (eGISP) and Strengthening the U.S. Response to Resistant Gonorrhea (SURRG). Methods During January 1, 2018–December 31, 2019, 12 eGISP and 8 SURRG sites collected urogenital, pharyngeal, and rectal isolates from cisgender MSM in STD clinics. Gonococcal isolates were sent to regional laboratories for antimicrobial susceptibility testing by agar dilution. To account for correlated observations, linear mixed-effects models were used to calculate geometric mean minimum inhibitory concentrations (MICs) and mixed-effects logistic regression models were used to calculate the proportion of isolates with elevated or resistant MICs; comparisons were made across anatomic sites. Results Participating clinics collected 3,974 urethral, 1,553 rectal, and 1,049 pharyngeal isolates from 5,456 unique cisgender MSM. There were no significant differences in the geometric mean MICs for azithromycin, ciprofloxacin, penicillin, and tetracycline by anatomic site. For cefixime and ceftriaxone, geometric mean MICs for pharyngeal isolates were higher compared to anogenital isolates (p< 0.05). The proportion of isolates with elevated ceftriaxone MICs (≥ 0.125 µg/ml) at the pharynx (0.67%) was higher than at rectal (0.13%) and urethral (0.18%) sites (p< 0.05). ![]()
Conclusion Based on data collected from multi-jurisdictional sentinel surveillance projects, antimicrobial susceptibility patterns of N. gonorrhoeae isolates may differ among MSM at extragenital sites, particularly at the pharynx. Continued investigation into gonococcal susceptibility patterns by anatomic site may be an important strategy to monitor and detect the emergence of antimicrobial resistant gonorrhea over time.

Abstract
Introduction The COVID-19 pandemic has had an extensive impact on the frail older population, with significant rates of COVID-related hospital admissions and deaths amongst this vulnerable group. There is little evidence of frailty prevalence amongst patients hospitalised with COVID-19, nor the impact of frailty on their survival. Methods Prospective observational study of all consecutive patients admitted to Salford Royal NHS Foundation (SRFT) Trust between 27th February and 28th April 2020 (wave 1), and 1st October to 10th November 2020 (wave 2) with a diagnosis of COVID-19. The primary endpoint was in-hospital mortality. Patient demographics, co-morbidities, admission level disease severity (estimated with CRP) and frailty (using the Clinical Frailty Scale, score 1–3 = not frail, score 4–9 = frail) were collected. A Cox proportional hazards regression model was used to assess the time to mortality. Results A total of 693 (N = 429, wave 1; N = 264, wave 2) patients were included, 279 (N = 180, 42%, wave 1; N = 104, 38%, wave 2) were female, and the median age was 72 in wave 1 and 73 in wave 2. 318 (N = 212, 49%, wave 1; N = 106, 39%, wave 2) patients presenting were frail. There was a reduction in mortality in wave 2, adjusted Hazard ratio (aHR) = 0.60 (95%CI 0.44–0.81; p = 0.001). There was an association between frailty and mortality aHR = 1.57 (95%CI 1.09–2.26; p = 0.015). Conclusion Frailty is highly prevalent amongst patients of all ages admitted to SRFT with COVID-19. Higher scores of frailty are associated with increased mortality.

Abstract
Introduction
The COVID-19 pandemic has had an extensive impact on the frail older population, with significant rates of COVID-related hospital admissions and deaths amongst this vulnerable group. There is little evidence comparing the prevalence and impact of frailty amongst patients hospitalised with COVID-19 in wave 1 vs wave 2 of the pandemic.
Methods
Prospective observational study of all consecutive patients admitted to Salford Royal NHS Foundation Trust (SRFT) between 27th February and 28th of April 2020 (wave 1), and 1st October to 10th November 2020 (wave 2) with a diagnosis of COVID-19. The primary endpoint was in-hospital mortality. Patient demographics, co-morbidities, biochemical parameters, and frailty (using the Clinical Frailty Scale, score 1–4 = not frail, score 5–9 = frail) were collected. A Cox proportional hazards model associating wave and frailty with mortality was used. A logistic regression model was used to associate patient characteristics with wave. Both models adjusted for patient characteristics.
Results
A total of 700 patients were included (N = 429, wave 1; N = 271, wave 2). In wave 1, 42% (N = 180) were female; median age was 72; 37% (N = 160) were non-survivors, 49% (N = 212) were frail (CFS 5–9). In wave 2, 38% (N = 104) were female; median age was 73; 30% (N = 80) were non-survivors, 39% (N = 106) were frail. There was a reduction in mortality in wave 2, aHR = 0.71 (95% CI 0.53–0.94). Frailty was associated with increased mortality, after adjustment for age, wave and other patient characteristics. Patients were more frail in wave 1, and the effect of frailty was more pronounced in wave 1 vs wave 2.
Conclusion
Frailty is highly prevalent amongst patients of all ages admitted to SRFT with COVID-19. Higher scores of frailty are associated with increased mortality.

Abstract
BACKGROUND Surgical intervention presents a fundamental therapeutic choice in the management of colorectal malignancies. Complications, the most serious one being anastomotic leak (AL), still have detrimental effects upon patients' morbidity and mortality. We aimed to assess whether NSAIDs, and their sub-categories, increase AL in colonic anastomoses and to identify whether this affects specific anastomotic sites. MATERIALS AND METHODS A systematic search of MEDLINE, Cochrane Library, ClinicalTrials.gov, Web of Science, Science Direct, Google Scholar was conducted between January 1, 1999 till the October 30, 2020. Cohort studies and randomized control trials examining AL events in NSAID-exposed, colorectal cancer patients were included. NSAIDs were grouped according to the 2019 NICE guidelines in non-specific (NS-NSAIDs) and specific COX-2 inhibitors. The primary outcome was AL events in NSAID-exposed patients undergoing operations with either ileocolic, colocolic or colorectal anastomoses. Secondary outcomes included NSAID category-specific AL events and demographic confounding factors increasing AL risk in this patient population. RESULTS Fifteen studies involving 25,395 patients were included in the systematic review and meta-analysis. Of all anastomoses, colocolic anastomoses were found to be statistically more prone to AL events in the NS-NSAID-exposed population [OR 3.24 (95% CI 0.98-10.72), p = 0.054]. Male gender was an independent confounder increasing AL rate regardless of NSAID exposure. CONCLUSION The association between NSAID exposure and AL in oncology patients remains undetermined. Whilst in present work, colocolic anastomoses appear to be more sensitive to AL events, the observed association may be anastomotic site and NSAID-category dependent.

Abstract
PURPOSE To report the course of ataxia in children up to 2 years post-operatively, following surgical resection of a posterior fossa tumour (PFT). METHODS Thirty-five children, (median age 9 years, range 4-15) having resection of PFT, were assessed using the Scale for the Assessment and Rating of Ataxia (SARA), Brief Ataxia Rating Scale (BARS) and the mobility domain of the Paediatric Evaluation of Disability Index (PEDI-m) at initial post-operative period (baseline), 3 months, 1 year and 2 years post-operatively. RESULTS Baseline median scores of the SARA and BARS were 8.5 (range 0-35.5), and 7 (0-25) respectively. Ataxia improved at 3 months (median SARA and BARS reduction 3.5 and 4, respectively). Additional gradual improvements in SARA were recorded at 1 (median reduction 2) and 2 years post-operatively (median reduction 0.5). Median baseline PEDI-m was 54.75 (range 15.2-100) with improvement at 3 months (median increase 36.95) and small improvement at 1 year (median increase 2.5) and 2 years (median increase 5.8). Children with medulloblastoma and midline tumours (median baseline SARA 10 and 11, respectively) demonstrated more severe ataxia than children with low-grade gliomas and unilateral tumours (median baseline SARA 7.5 and 6.5, respectively). CONCLUSION The largest improvement in ataxia scores and functional mobility scores is demonstrated within the first 3 months post-operatively, but ongoing gradual improvement is observed at 2 years. Children with medulloblastoma and midline tumour demonstrated higher ataxia scores long term.

Increased care at discharge from COVID-19: The association between pre-admission frailty and increased care needs after hospital discharge; a multicentre European observational cohort study. BMC Med 2020; 18:408. [PMID: 33334341 PMCID: PMC7746415 DOI: 10.1186/s12916-020-01856-8] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2020] [Accepted: 11/17/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The COVID-19 pandemic has placed significant pressure on health and social care. Survivors of COVID-19 may be left with substantial functional deficits requiring ongoing care. We aimed to determine whether pre-admission frailty was associated with increased care needs at discharge for patients admitted to hospital with COVID-19. METHODS Patients were included if aged over 18 years old and admitted to hospital with COVID-19 between 27 February and 10 June 2020. The Clinical Frailty Scale (CFS) was used to assess pre-admission frailty status. Admission and discharge care levels were recorded. Data were analysed using a mixed-effects logistic regression adjusted for age, sex, smoking status, comorbidities, and admission CRP as a marker of severity of disease. RESULTS Thirteen hospitals included patients: 1671 patients were screened, and 840 were excluded including, 521 patients who died before discharge (31.1%). Of the 831 patients who were discharged, the median age was 71 years (IQR, 58-81 years) and 369 (44.4%) were women. The median length of hospital stay was 12 days (IQR 6-24). Using the CFS, 438 (47.0%) were living with frailty (≥ CFS 5), and 193 (23.2%) required an increase in the level of care provided. Multivariable analysis showed that frailty was associated with an increase in care needs compared to patients without frailty (CFS 1-3). The adjusted odds ratios (aOR) were as follows: CFS 4, 1.99 (0.97-4.11); CFS 5, 3.77 (1.94-7.32); CFS 6, 4.04 (2.09-7.82); CFS 7, 2.16 (1.12-4.20); and CFS 8, 3.19 (1.06-9.56). CONCLUSIONS Around a quarter of patients admitted with COVID-19 had increased care needs at discharge. Pre-admission frailty was strongly associated with the need for an increased level of care at discharge. Our results have implications for service planning and public health policy as well as a person's functional outcome, suggesting that frailty screening should be utilised for predictive modelling and early individualised discharge planning.

Risk factors for incident delirium among urological patients: a systematic review and meta-analysis with GRADE summary of findings. BMC Urol 2020; 20:169. [PMID: 33109133 PMCID: PMC7590461 DOI: 10.1186/s12894-020-00743-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Accepted: 10/14/2020] [Indexed: 12/02/2022] Open
Abstract
Background Post-operative delirium is an important, yet under-researched complication of surgery. Patients undergoing urological surgery may be at especially high risk of POD, as they are often older, and interventions can be associated with conditions that trigger delirium. The main aim of this systematic review was to evaluate the available evidence for risk factors in this patient group. Methods Five databases were searched (MEDLINE, Web of Science, EMBASE, CINAHL and PsychInfo) between January 1987 and June 2019. The Newcastle–Ottawa Scale was used to assess for risk of bias. Pooled odds ratio or mean difference (MD) for individual risk factors were estimated using the Mantel–Haenzel and inverse variance methods. Results Seven articles met the inclusion criteria, giving a total population of 1937. The incidence of POD ranged from 5 to 29%. Three studies were deemed low risk of bias and four at a high risk of bias. Nine risk factors were suitable for meta-analysis, with age (MD 4.314 95% CI 1.597, 7.032 p = 0.002) and the clock drawing test (MD − 2.443 95% CI − 3.029, − 1.857 p < 0.001) having a statistically significant association with POD in pooled analyses. Conclusion Delirium is common in urological patients. This review has identified a lack of studies in this surgical population, with wide heterogeneity and high risk of bias. It also highlights a number of potential risk factors for post-operative delirium, of which some are modifiable. However, the strength of evidence is weak at present and so future research should focus on assessing comparable risk factors in this patient group in order to inform future clinical practice. Review registration The review protocol was prospectively registered with the PROSPERO database (reference CRD42017054613)

Abstract
Background Hospital admissions for non-coronavirus disease 2019 (COVID-19) pathology have decreased significantly. It is believed that this may be due to public anxiety about acquiring COVID-19 infection in hospital and the subsequent risk of mortality. Aim To identify patients who acquire COVID-19 in hospital (nosocomial COVID-19 infection (NC)) and their risk of mortality compared to those with community-acquired COVID-19 (CAC) infection. Methods The COPE-Nosocomial Study was an observational cohort study. The primary outcome was the time to all-cause mortality (estimated with an adjusted hazard ratio (aHR)), and secondary outcomes were day 7 mortality and the time-to-discharge. A mixed-effects multivariable Cox's proportional hazards model was used, adjusted for demographics and comorbidities. Findings The study included 1564 patients from 10 hospital sites throughout the UK, and one in Italy, and collected outcomes on patients admitted up to April 28th, 2020. In all, 12.5% of COVID-19 infections were acquired in hospital; 425 (27.2%) patients with COVID died. The median survival time in NC patients was 14 days compared with 10 days in CAC patients. In the primary analysis, NC infection was associated with lower mortality rate (aHR: 0.71; 95% confidence interval (CI): 0.51–0.98). Secondary outcomes found no difference in day 7 mortality (adjusted odds ratio: 0.79; 95% CI: 0.47–1.31), but NC patients required longer time in hospital during convalescence (aHR: 0.49, 95% CI: 0.37–0.66). Conclusion The minority of COVID-19 cases were the result of NC transmission. No COVID-19 infection comes without risk, but patients with NC had a lower risk of mortality compared to CAC infection; however, caution should be taken when interpreting this finding.

Abstract
Abstract
Background
Older adults undergoing emergency abdominal surgery have significantly poorer outcomes than younger adults. For those who survive, the level of care required on discharge from hospital is unknown and such information could guide decision-making. The ELF (Emergency Laparotomy and Frailty) study aimed to determine whether preoperative frailty in older adults was associated with increased dependence at the time of discharge.
Methods
The ELF study was a UK-wide multicentre prospective cohort study of older patients (65 years or more) undergoing emergency laparotomy during March and June 2017. The objective was to establish whether preoperative frailty was associated with increased care level at discharge compared with preoperative care level. The analysis used a multilevel logistic regression adjusted for preadmission frailty, patient age, sex and care level.
Results
A total of 934 patients were included from 49 hospitals. Mean(s.d.) age was 76·2(6·8) years, with 57·6 per cent women; 20·2 per cent were frail. Some 37·4 per cent of older adults had an increased care level at discharge. Increasing frailty was associated with increased discharge care level, with greater predictive power than age. The adjusted odds ratio for an increase in care level was 4·48 (95 per cent c.i. 2·03 to 9·91) for apparently vulnerable patients (Clinical Frailty Score (CFS) 4), 5·94 (2·54 to 13·90) for those mildly frail (CFS 5) and 7·88 (2·97 to 20·79) for those moderately or severely frail (CFS 6 or 7), compared with patients who were fit.
Conclusion
Over 37 per cent of older adults undergoing emergency laparotomy required increased care at discharge. Frailty scoring was a significant predictor, and should be integrated into all acute surgical units to aid shared decision-making and discharge planning.

Abstract
BACKGROUND Rosacea is a common chronic facial dermatosis. Classification of rosacea has evolved from subtyping to phenotyping. OBJECTIVES To update our systematic review on interventions for rosacea. METHODS We searched CENTRAL, MEDLINE, Embase, LILACS, Science Citation Index and ongoing trials registers (March 2018) for randomized controlled trials. Study selection, data extraction, risk-of-bias assessment and analyses were carried out independently by two authors. Grading of Recommendations, Assessment, Development and Evaluations (GRADE) was used to assess certainty of evidence. RESULTS We included 152 studies (46 were new), comprising 20 944 participants. Topical interventions included brimonidine, oxymetazoline, metronidazole, azelaic acid, ivermectin and other topical treatments. Systemic interventions included oral antibiotics, combinations with topical treatments or other systemic treatments. Several studies evaluated laser or light-based treatment. We present the most current evidence for rosacea management based on a phenotype-led approach. CONCLUSIONS For reducing temporarily persistent erythema there was high-certainty evidence for topical brimonidine and moderate certainty for topical oxymetazoline; for erythema and mainly telangiectasia there was low-to-moderate-certainty evidence for laser and intense pulsed light therapy. For reducing papules/pustules there was high-certainty evidence for topical azelaic acid and topical ivermectin; moderate-to-high-certainty evidence for doxycycline 40 mg modified release (MR) and isotretinoin; and moderate-certainty evidence for topical metronidazole, and topical minocycline and oral minocycline being equally effective as doxycycline 40 mg MR. There was low-certainty evidence for tetracycline and low-dose minocycline. For ocular rosacea, there was moderate-certainty evidence that oral omega-3 fatty acids were effective and low-certainty evidence for ciclosporin ophthalmic emulsion and doxycycline.

Abstract
BACKGROUND frail patients in any age group are more likely to die than those that are not frail. We aimed to evaluate the impact of frailty on clinical mortality, readmission rate and length of stay for emergency surgical patients of all ages. METHODS a multi-centre prospective cohort study was conducted on adult admissions to acute surgical units. Every patient presenting as a surgical emergency to secondary care, regardless of whether they ultimately underwent a surgical procedure was included. The study was carried out during 2015 and 2016.Frailty was defined using the 7-point Clinical Frailty Scale. The primary outcome was mortality at Day 90. Secondary outcomes included: mortality at Day 30, length of stay and readmission within a Day 30 period. RESULTS the cohort included 2,279 patients (median age 54 years [IQR 36-72]; 56% female). Frailty was documented in patients of all ages: 1% in the under 40's to 45% of those aged 80+. We found that each incremental step of worsening frailty was associated with an 80% increase in mortality at Day 90 (OR 1.80, 95% CI: 1.61-2.01) supporting a linear dose-response relationship. In addition, the most frail patients were increasingly likely to stay in hospital longer, be readmitted within 30 days, and die within 30 days. CONCLUSIONS worsening frailty at any age is associated with significantly poorer patient outcomes, including mortality in unselected acute surgical admissions. Assessment of frailty should be integrated into emergency surgical practice to allow prognostication and implementation of strategies to improve outcomes.

Abstract
This study assessed attitudes toward HIV and awareness of previous HIV prevention campaigns among young black men in the United States of America (USA). The study also ascertained the appropriateness of HIV testing messages for young black men and explored the use of social networking sites to deliver HIV testing messages for social media marketing campaigns. Nineteen (n = 19) black male college students attending a public university in Atlanta, GA, USA from September 2016 to October 2016 participated in three focus groups. The focus groups consisted of a group interview querying experiences with HIV and STI testing, awareness of HIV campaigns, solicited feedback on campaign messages and the use of social networking sites to deliver messages. Data analysis involved the grounded theory approach to identify emergent themes. Fear, stigma and low risk perception were discussed as barriers to HIV testing. HIV prevention, social support and new sexual partners were discussed as reasons for testing. There was a general lack of awareness of existing HIV testing campaigns. Messaging with a universal appeal and disseminated through Twitter, Instagram and Snapchat may counter narratives of fear, stigma and low risk perception to increase HIV testing among young black men.

Abstract
BACKGROUND Low albumin is a prognostic factor associated with poor surgical outcomes. We aimed to examine the predicative ability of easily obtainable point-of-care variables in combination, to derive a practical risk scale for predicting older adults at risk of poor outcomes on admission to the emergency general surgical setting. METHODS This is an international multi-center prospective cohort study conducted as part of the Older Persons Surgical Outcomes Collaboration (www.OPSOC.eu). The effect of having hypoalbuminemia (defined as albumin ≤3.5 g/dL) on selected outcomes was examined using fully adjusted multivariable models. In a subgroup of patients with hypoalbuminemia, we observed four risk characteristics (Male, Anemia, Low albumin, Eighty-five and over [MALE]). Subsequently, the impact of incremental increase in MALE score (each characteristic scoring 1 point (maximum score 4) on measured outcomes was assessed. RESULTS The cohort consisted of 1406 older patients with median (IQR) age of 76 (70-83) years. In fully adjusted models, hypoalbuminemia was significantly associated with undergoing emergency surgery (1.32 (95%CI 1.03-1.70); p = 0.03), 30-day mortality (4.23 (2.22-8.08); p < 0.001), 90-day mortality (3.36 (2.14-5.28); p < 0.001) (primary outcome), and increased hospital length of stay, irrespective of whether a patient received emergency surgical intervention. Every point increase in MALE score was associated with higher odds of mortality, with a MALE score of 4 being associated with 30-day mortality (adjusted OR(95% CI) = 33.38 (3.86-288.7); p = 0.001) and 90-day mortality (11.37 (3.85-33.59); p < 0.001) compared to the reference category of those with MALE score 0. CONCLUSIONS The easy to use and practical MALE risk score calculated at point of care identifies older adults at a greater risk of poor outcomes, thereby allowing clinicians to prioritize patients who may benefit from early comprehensive geriatric assessment in the emergency general surgical setting.

Efficacy of β-mannanase on broiler growth performance and energy utilization in the presence of increasing dietary galactomannan. Poult Sci 2018; 97:549-556.

Abstract
An experiment was conducted to investigate the impact of β-mannanase inclusion on growth performance, viscosity, and energy utilization in broilers fed diets varying in galactomannan (GM) concentrations. Treatments were arranged as a 3 (GM concentration) × 3 (β-mannanase inclusion) factorial randomized complete block design with 12 replicates of 29 male broilers per replicate for a 42-d experiment. Efforts were made to reduce the amount of soybean meal, and thus GM, in the basal diet with guar gum included at 0, 0.21, or 0.42% to achieve a GM supplementation of 1,500 and 3,000 ppm, respectively. Beta-mannanase was included at 0, 200, or 400 g/ton. Broilers were fed a starter (d 0 to 14), grower (d 15 to 28), and finisher diets (d 29 to 42). Growth performance was monitored and ileal contents collected on d 14, 28, and 42 to determine ileal digestible energy (IDE) and intestinal viscosity. Increasing levels of GM negatively (P < 0.05) influenced body weight (BW) following the starter and grower periods and increased (P < 0.01) mortality corrected feed conversion ratio (FCR) throughout the study. Reduced growth performance was associated with increased (P < 0.05) intestinal viscosity and decreased (P < 0.05) IDE when GM inclusion was increased. Inclusion of β-mannanase in diets containing supplemental GM on d 28, increased average BW to levels similar to diets without supplemental GM. Improvements in FCR were also observed with β-mannanase inclusion in diets containing supplemental GM. Ileal digestible energy was increased (P < 0.05) with the addition of β-mannanase on d 28 of age. Multiple interactions in growth performance, intestinal viscosity, and IDE were associated with β-mannanase administration. In conclusion, β-mannanase improved IDE, reduced intestinal viscosity, and improved growth performance; however, the observed benefit was dependent upon dietary GM concentration.

Abstract
β-galactomannans found in soy-based broiler feed are known to cause physiological effects that are hypothesized to be related to gut inflammation. Previous studies have shown that the incorporation of β-mannanase in the diet or as a supplement results in improvements to certain performance parameters related to gut health and feed conversion. Using kinome analysis, we characterized the mechanism of β-galactomannan activity and supplementation with β-mannanase on the gut of commercial broilers to understand the mode of action. Two doses of β-mannanase (200 and 400 g/ton of feed) with and without inclusion of additional β-galactomannan (3,000 ppm) were tested at 3 time points (d 14, d 28, and d 42 post hatch). Broilers were fed starter (d 0 to 14), grower (d 15 to 28), and finisher diets (d 29 to 42). Jejuna were collected from birds from each treatment condition and time point. Cluster analysis of the kinome data showed that birds clustered first by age, then predominantly by whether β-mannanase had been included in the diet. Biological pathway analysis showed that the inclusion of additional β-galactomannan into the diet resulted in increased signaling related to immune response, relative to our normal control diet (with reduced soybean meal). The addition of β-mannanase to the enhanced β-galactomannan diet eliminated the majority of this immune-related signaling, indicating that the feed-induced immune response within the jejuna had been eliminated by the addition of β-mannanase. We also saw changes in specific metabolic and gut function pathways in birds fed β-mannanase. These observed changes in β-mannanase-fed birds are likely the mechanism for the enhanced performance and feed conversion observed in birds given β-mannanase in their diets.

Abstract
BACKGROUND Frailty is prevalent in the older adult population (≥65 years of age) and results in adverse outcomes in the emergency general surgical population. OBJECTIVE To determine whether frailty exists in the younger adult emergency surgical population (<65 years) and what influence frailty may have on patient related outcomes. DESIGN Prospective observational cohort study. SETTING Emergency general surgical admissions. PARTICIPANTS All patients ≥40 years divided into 2 groups: younger adults (40-64.9 years) and older adult comparative group (≥65). MEASUREMENTS Over a 6-month time frame the following data was collected: demographics; Scottish Index of Multiple Deprivation (SIMD); blood markers; multi-morbidities, polypharmacy and cognition. Frailty was assessed by completion of the Canadian Study of Health and Ageing (CSHA). Each patient was followed up for 90 days to allow determination of length of stay, re-admission and mortality. RESULTS 82 young adults were included and the prevalence of frailty was 16% (versus older adults 38%; p=0.001) and associated with: multi-morbidity; poly-pharmacy; cognitive impairment; and deprivation. Frailty in older adults was only significantly associated with increasing age. CONCLUSIONS This novel study has found that frailty exists in 16% of younger adults admitted to emergency general surgical units, potentially leading to adverse short and long-term outcomes. Strategies need to be developed that identify and treat frailty in this vulnerable younger adult population.

The inferomedial femoral neck is compromised by age but not disease: Fracture toughness and the multifactorial mechanisms comprising reference point microindentation. J Mech Behav Biomed Mater 2017; 75:399-412. [PMID: 28803114 PMCID: PMC5619645 DOI: 10.1016/j.jmbbm.2017.06.036] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2017] [Revised: 06/26/2017] [Accepted: 06/28/2017] [Indexed: 12/19/2022]
Abstract
The influence of ageing on the fracture mechanics of cortical bone tissue is well documented, though little is known about if and how related material properties are further affected in two of the most prominent musculoskeletal diseases, osteoporosis and osteoarthritis (OA). The femoral neck, in close proximity to the most pertinent osteoporotic fracture site and near the hip joint affected by osteoarthritis, is a site of particular interest for investigation. We have recently shown that Reference Point micro-Indentation (RPI) detects differences between cortical bone from the femoral neck of healthy, osteoporotic fractured and osteoarthritic hip replacement patients. RPI is a new technique with potential for in vivo bone quality assessment. However, interpretation of RPI results is limited because the specific changes in bone properties with pathology are not well understood and, further, because it is not conclusive what properties are being assessed by RPI. Here, we investigate whether the differences previously detected between healthy and diseased cortical bone from the femoral neck might reflect changes in fracture toughness. Together with this, we investigate which additional properties are reflected in RPI measures. RPI (using the Biodent device) and fracture toughness tests were conducted on samples from the inferomedial neck of bone resected from donors with: OA (41 samples from 15 donors), osteoporosis (48 samples from 14 donors) and non age-matched cadaveric controls (37 samples from 10 donoros) with no history of bone disease. Further, a subset of indented samples were imaged using micro-computed tomography (3 osteoporotic and 4 control samples each from different donors) as well as fluorescence microscopy in combination with serial sectioning after basic fuchsin staining (7 osteoporotic and 5 control samples from 5 osteoporotic and 5 control donors). In this study, the bulk indentation and fracture resistance properties of the inferomedial femoral neck in osteoporotic fracture, severe OA and control bone were comparable (p > 0.05 for fracture properties and <10% difference for indentation) but fracture toughness reduced with advancing age (7.0% per decade, r = -0.36, p = 0.029). Further, RPI properties (in particular, the indentation distance increase, IDI) showed partial correlation with fracture toughness (r = -0.40, p = 0.023) or derived elastic modulus (r = -0.40, p = 0.023). Multimodal indent imaging revealed evidence of toughening mechanisms (i.e. crack deflection, bridging and microcracking), elastoplastic response (in terms of the non-conical imprint shape and presence of pile-up) and correlation of RPI with damage extent (up to r = 0.79, p = 0.034) and indent size (up to r = 0.82, p < 0.001). Therefore, crack resistance, deformation resistance and, additionally, micro-structure (porosity: r = 0.93, p = 0.002 as well as pore proximity: r = -0.55, p = 0.027 for correlation with IDI) are all contributory to RPI. Consequently, it becomes clear that RPI measures represent a multitude of properties, various aspects of bone quality, but are not necessarily strongly correlated to a single mechanical property. In addition, osteoporosis or osteoarthritis do not seem to further influence fracture toughness of the inferomedial femoral neck beyond natural ageing. Since bone is highly heterogeneous, whether this finding can be extended to the whole femoral neck or whether it also holds true for other femoral neck quadrants or other material properties remains to be shown.

Role of nutritional status and intervention in oesophageal cancer treated with definitive chemoradiotherapy: outcomes from SCOPE1. Br J Cancer 2016; 115:172-7.

Abstract
BACKGROUND Malnutrition is common in oesophageal cancer. We aimed to identify nutritional prognostic factors and survival outcomes associated with nutritional intervention in the SCOPE1 (Study of Chemoradiotherapy in OesoPhageal Cancer with or without Erbitux) trial. METHODS Two hundred and fifty eight patients were randomly allocated to definitive chemoradiotherapy (dCRT) +/- cetuximab. Nutritional Risk Index (NRI) scores were calculated; NRI<100 identified patients at risk of malnutrition. Nutritional intervention included dietary advice, oral supplementation or major intervention (enteral feeding/tube placement). Univariable and multivariable analyses using Cox proportional hazard modelling were conducted. RESULTS At baseline NRI<100 strongly predicted for reduced overall survival (hazard ratio (HR) 12.45, 95% CI 5.24-29.57; P<0.001). Nutritional intervention improved survival if provided at baseline (dietary advice (HR 0.12, P=0.004), oral supplementation (HR 0.13, P<0.001) or major intervention (HR 0.13, P=0.003)), but not if provided later in the treatment course. Cetuximab patients receiving major nutritional intervention had worse outcomes compared with controls (13 vs 28 months, P=0.003). CONCLUSIONS Pre-treatment assessment and correction of malnutrition may improve survival outcomes in oesophageal cancer patients treated with dCRT. Nutritional Risk Index is a simple and objective screening tool to identify patients at risk of malnutrition.

Abstract
Tritium emissions are one of the main concerns with regard to CANDU reactors and Canadian nuclear facilities. After the Fukushima accident, the Canadian Nuclear Regulatory Commission suggested that models used in risk assessment of Canadian nuclear facilities be firmly based on measured data. Procedures for measurement of tritium as HTO (tritiated water) are well established, but there are no standard methods and certified reference materials for measurement of organically bound tritium (OBT) in environmental samples. This paper describes and discusses an inter-laboratory comparison study in which OBT in three different dried environmental samples (fish, Swiss chard and potato) was measured to evaluate OBT analysis methods currently used by CANDU Owners Group (COG) members. The variations in the measured OBT activity concentrations between all laboratories were less than approximately 20%, with a total uncertainty between 11 and 17%. Based on the results using the dried samples, the current OBT analysis methods for combustion, distillation and counting are generally acceptable. However, a complete consensus OBT analysis methodology with respect to freeze-drying, rinsing, combustion, distillation and counting is required. Also, an exercise using low-level tritium samples (less than 100 Bq/L or 20 Bq/kg-fresh) would be useful in the near future to more fully evaluate the current OBT analysis methods.
