Abstract
BACKGROUND AND PURPOSE Walker-Warburg syndrome, muscle-eye-brain disease, and Fukuyama congenital muscular dystrophy are α-dystroglycan-related muscular disorders associated with brain malformations and eye abnormalities in which no structural inner ear abnormality has been described radiologically. We collected patients from 6 tertiary pediatric hospitals and reported the radiologic features and frequency of inner ear dysplasias. MATERIALS AND METHODS Patients previously diagnosed clinicoradiologically with Walker-Warburg syndrome, muscle-eye-brain disease, or Fukuyama congenital muscular dystrophy were included. We recorded the pathogenic variant, when available. Brain MR imaging and/or CT findings were reviewed in consensus, and inner ear anomalies were classified according to previous description in the literature. We then correlated the clinicoradiologic phenotype with the inner ear phenotype. RESULTS Thirteen patients fulfilled the criteria for the Walker-Warburg syndrome phenotype, 8 for muscle-eye-brain disease, and 3 for Fukuyama congenital muscular dystrophy. A dysplastic cochlea was demonstrated in 17/24. The most frequent finding was a pronounced cochlear hypoplasia type 4 with a very small anteriorly offset turn beyond the normal-appearing basal turn (12/13 patients with Walker-Warburg syndrome and 1/11 with muscle-eye-brain disease or Fukuyama congenital muscular dystophy). Two of 8 patients with muscle-eye-brain disease, 1/3 with Fukuyama congenital muscular dystrophy, and 1/13 with Walker-Warburg syndrome showed a less severe cochlear hypoplasia type 4. The remaining patients without Walker-Warburg syndrome were healthy. The vestibule and lateral semicircular canals of all patients were normal. Cranial nerve VIII was present in all patients with diagnostic MR imaging. CONCLUSIONS Most patients with the severe α-dystroglycanopathy Walker-Warburg syndrome phenotype have a highly characteristic cochlear hypoplasia type 4. Patients with the milder variants, muscle-eye-brain disease and Fukuyama congenital muscular dystrophy, more frequently have a normal cochlea or milder forms of hypoplasia.

Abstract
OBJECTIVE Recently, two influential articles that reported the association of (hydroxy)chloroquine or angiotensin converting enzyme (ACE) inhibitors and coronavirus disease 2019 (COVID-19) mortality were retracted due to significant methodological issues. Therefore, we aimed to analyze the same clinical issues through an improved research method and to find out the differences from the retracted papers. We systematically reviewed pre-existing literature, and compared the results with those of the retracted papers to gain a novel insight. MATERIALS AND METHODS We extracted common risk factors identified in two retracted papers, and conducted relevant publication search until June 26, 2020 in PubMed. Then, we analyzed the risk factors for COVID-19 mortality and compared them to those of the retracted papers. RESULTS Our systematic review demonstrated that most demographic and clinical risk factors for COVID-19 mortality were similar to those of the retracted papers. However, while the retracted paper indicated that both (hydroxy)chloroquine monotherapy and combination therapy with macrolide were associated with higher risk of mortality, our study showed that only combination therapy of hydroxychloroquine and macrolide was associated with higher risk of mortality (odds ratio 2.33; 95% confidence interval 1.63-3.34). In addition, our study demonstrated that use of ACE inhibitors or angiotensin receptor blockers (ARBs) was associated with reduced risk of mortality (0.77; 0.65-0.91). CONCLUSIONS When analyzing the same clinical issues with the two retracted papers through a systematic review of randomized controlled trials and relevant cohort studies, we found out that (hydroxy)chloroquine monotherapy was not associated with higher risk of mortality, and that the use of ACE inhibitors or ARBs was associated with reduced risk of mortality in COVID-19 patients.

Abstract
OBJECTIVE Hematologic cancer patients with Coronavirus Disease 2019 (COVID-19) tend to have a more serious disease course than observed in the general population. Herein, we comprehensively reviewed existing literature and analyzed clinical characteristics and mortality of patients with hematologic malignancies and COVID-19. MATERIALS AND METHODS Through searching PubMed until June 03, 2020, we identified 16 relevant case studies (33 cases) from a total of 45 studies that have reported on patients with COVID-19 and hematologic malignancies. We investigated the clinical and laboratory characteristics including type of hematologic malignancies, initial symptoms, laboratory findings, and clinical outcomes. Then, we compared those characteristics and outcomes of patients with hematologic malignancies and COVID-19 to the general population infected with COVID-19. RESULTS The median age was 66-year-old. Chronic lymphocytic leukemia was the most common type of hematologic malignancy (39.4%). Fever was the most common symptom (75.9%). Most patients had normal leukocyte counts (55.6%), lymphocytosis (45.4%), and normal platelet counts (68.8%). In comparison to patients with COVID-19 without underlying hematologic malignancies, dyspnea was more prevalent (45.0 vs. 24.9%, p=0.025). Leukocytosis (38.9 vs. 9.8%, p=0.001), lymphocytosis (45.4 vs. 8.2%, p=0.001), and thrombocytopenia (31.3 vs. 11.4%, p=0.036) were significantly more prevalent and lymphopenia (18.2 vs. 57.4%, p=0.012) less prevalent in patients with hematologic malignancies. There were no clinical and laboratory characteristics predicting mortality in patients with hematologic malignancies. Mortality was much higher in patients with hematologic malignancies compared to those without this condition (40.0 vs. 3.6%, p<0.001). CONCLUSIONS Co-occurrence of hematologic malignancies and COVID-19 is rare. However, due to the high mortality rate from COVID-19 in this vulnerable population, further investigation on tailored treatment and management is required.

Abstract
Multi-modality treatment strategies are more becoming commonplace in veterinary oncology practice yet the evidence base is far inferior to what has been generated in people. Surgery is unquestionably the cornerstone of most solid tumour treatment plans but certain scenarios dictate combining surgery with systemic chemotherapy and radiation therapy as an adjunct. By using these in the neoadjuvant setting, one can leverage certain effects of the treatment to improve local disease control, improve overall survival, gain insight into drug efficacy, reduce surgical morbidity and reduce long-term complications. An unintended consequence of combining therapies is an increased flow of information between members of the care team upfront that in almost all cases leads to improved patient outcomes albeit a difficult metric to quantify. This review sets out to explore some of the principles of neoadjuvant therapies and discuss potential opportunities to expand the evidence base in veterinary medicine.

A commercial autogenous injection vaccine protects ballan wrasse (Labrus bergylta, Ascanius) against Aeromonas salmonicida vapA type V. FISH & SHELLFISH IMMUNOLOGY 2020; 107:43-53. [PMID: 33011432 DOI: 10.1016/j.fsi.2020.09.040] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Revised: 09/22/2020] [Accepted: 09/28/2020] [Indexed: 06/11/2023]
Abstract
Atypical Aeromonas salmonicida (aAs) and Vibrionaceae related species are bacteria routinely recovered from diseased ballan wrasse used as cleaner fish in the Atlantic salmon farming industry. Autogenous (i.e. farm specific inactivated) multivalent vaccines formulated from these microorganisms are widely used to protect farmed wrasse despite limited experimental proof that they are primary pathogens. In this study, the components of a commercial multivalent injection vaccine containing four strains of Aeromonas salmonicida and one strain of Vibrio splendidus previously isolated from ballan wrasse in Scotland, were tested for infectivity, pathogenicity and virulence via intra peritoneal injection at pre-deployment size (25-50 g) and the efficacy of the vaccine for protection against aAs assessed. Injection with 3.5 × 109, 8 × 109 1.8 × 109 and 5 × 109 cfu/fish of Vibrio splendidus, V. ichthyoenteri, Aliivibrio logeii and A. salmonicida, respectively, did not cause significant mortalities, lesions or clinical signs after a period of 14 days. IP injection with both aAs and Photobacterium indicum successfully reproduced the clinical signs and internal lesions observed during natural outbreaks of the disease. Differences in virulence (LD50 at day 8-post infection of 3.6 × 106 cfu/fish and 1.6 × 107 cfu/fish) were observed for two aAs vapA type V isolates. In addition, the LD50 for Photobacterium indicum was 2.2 × 107 cfu/fish. The autogenous vaccine was highly protective against the two aAs vapA type V isolates after 700-degree days of immunisation. The RPSFINAL values for the first isolate were 95 and 91% at 1 × 106 cfu/fish and 1 × 107 cfu/fish, respectively, and 79% at 1 × 107 cfu/fish for the second isolate tested. In addition, significantly higher anti aAs seral antibodies (IgM), were detected by ELISA in vaccinated fish in contrast with control (mock vaccinated) fish. These results suggest wrasse can be effectively immunised and protected against aAs infection by injection with oil adjuvanted vaccines prepared with inactivated homologous isolates.

Abstract
BACKGROUND Sedentary occupations have increased by more than 10% in Western countries over the last two decades, and the yearly global cost of physical inactivity has been estimated to be $53.8 billion. As workers tend to move less in the workplace, they are more likely to develop a sedentarism-related chronic condition and to be absent from work due to illness, although research evidence on the issue remains unclear. AIMS To investigate associations between physical activity (PA) and sickness absenteeism in the workplace among Spanish university workers. METHODS We conducted cross-sectional research with data from 1025 workers aged 18-65 years (43% women) from a Spanish university. Physical Activity Vital Sign (PAVS) and International Physical Activity Questionnaire (IPAQ) short versions were used to evaluate levels of PA. Workplace absenteeism was self-reported by participants. Written questionnaires distributed during medical checks included PAVS, IPAQ and the question about absenteeism among other information. The association between PA and sickness absenteeism was examined using adjusted multiple linear regression. RESULTS After adjusting for age, sex, job function, chronic conditions, sedentarism and smoking, each weekly hour of PA reduced sickness absence by -1.20 (95% confidence interval: -2.40-0.00) days per year. CONCLUSIONS The implementation of PA promotion strategies aimed at university employees may lead to a reduction of days off work due to illness.

Abstract
BACKGROUND To date there is limited literature on the prevalence of chronic skin conditions and its association with levels of physical activity (PA) in Spain. AIM To determine the prevalence of chronic skin disease and to compare levels of PA between people with and without chronic skin disease in a large representative sample of Spanish adults aged 15-69 years. METHODS Data from the Spanish National Health Survey 2017 were analysed. Chronic skin disease was assessed using a yes/no question. PA was measured using the short form of the International Physical Activity Questionnaire. Total PA metabolic equivalent of task min/week were calculated, and PA was included in the analyses as a continuous and a five-category variable. RESULTS This cross-sectional study included 17 777 adult participants (52.0% women; mean ± SD age 45.8 ± 14.1 years), of whom 940 (5.3%) had chronic skin disease. After adjusting for several potential confounders, there was a negative association between chronic skin disease and PA (OR = 0.87, 95% CI 0.76-1.00, P = 0.05), which was significant for men (OR = 0.76, 95% CI 0.62-0.93, P = 0.01) but not for women (OR = 0.97, 95% CI 0.81-1.16, P = 0.72). CONCLUSIONS In this large representative sample of Spanish adults, the prevalence of chronic skin disease was low. Levels of PA were lower in men with than in men without chronic skin conditions, but this association was not seen in women.

Abstract
Abstract
Background
Jigawa and Kano States, Northern Nigeria have some of the worst human development outcomes globally for adolescents across a wide range of health indicators. Our aim was to understand health awareness, beliefs, and behaviours of adolescents in school in Jigawa and Kano States, to inform prioritization and development of health promotion interventions in the region.
Methods
We carried out a cross-sectional survey followed by focus group discussions (FGDs) with adolescents aged 15 to 20 years from four schools in Jigawa and Kano States (July-August 2019). Adolescents (274 per school) were randomly selected stratified by class-year (SS1 and SS2); 64 participated in FGDs (8 groups of 8). Trained researchers administered a questionnaire face-to-face via smart phones. Topics included: mental health; tobacco use; substance misuse; violence and unintentional injury; physical and dietary behaviours; and hygiene. FGDs investigated topics in greater depth. Here we report prevalence and predictors of mental health calculated from survey responses, and thematic analysis of interview findings.
Results
One thousand and seventy-nine students completed the survey (98%);∼50% girls. Preliminary analysis showed prevalence of moderate-severe anxiety was higher in girls than boys (6.8% girls, 0.8% boys, p < 0.001); and moderate-severe depression (10.3% girls, 0.5% boys, p < 0.001). Up to 50% boys and girls experienced violence or abuse in school, and 16% used a prescription drug without a prescription in past 30 days. Multivariable logistic regression showed female gender (aOR =4.0, 95% CI; 2.7,6.0); 30-day off-prescription drug use - aOR=2.3 (1.5,3.8); and being hit or slapped by a teacher - aOR=1.7, (1.1, 2.6) were predictors of moderate to severe anxiety. Results were similar for moderate to severe depression. Qualitative findings supported and contextualized these results.
Conclusions
Results will inform school-based interventions to improve health of adolescents in the region.
Key messages
Administering a health questionnaire to gather health information of adolescents in school in Kano and Jigawa states, Nigeria was feasible. Health questionnaire and focus group data will be shared with school and community leaders to shape school-based interventions to improve health outcomes amongst adolescents.

Abstract
Abstract
Background
Bowel cancer is common and accounts for 10% of all cancer mortality. Early detection significantly reduces mortality. In the UK, the NHS Bowel Cancer Screening Programme invites adults aged 60-74 years to carry out a home screening test biennially. The national target for test completion is 60%; completion is substantially lower (∼30%) amongst South Asian populations. Our aim was to develop a community-based intervention to increase completion of the home bowel screening test in South Asians.
Methods
Multi-methods comprising two stages: 1) group and individual interviews with South Asians aged 50-74 years purposively sampled from community groups for maximum variation. Semi-structured interviews based on the Theoretical Domains Framework (TDF) investigated determinants of bowel screening completion. Interviews were recorded, transcribed, and analysed using framework analysis and findings mapped onto the COM-B Behaviour Change Wheel; 2) Co-production of intervention during two workshops with key stakeholders and target population.
Results
To-date 25 adults recruited of Indian, Pakistani and Bangladeshi ethnicity with variation in age, gender, first language, faith, and compliance with bowel screening. Key barriers and TDF domains that they mapped to were: - lack of knowledge about bowel cancer and screening; lack of language, literacy and physical ability (skills) to carry out the home test; confidence to carry it out correctly (belief about capabilities); appropriate space and time to carry out the test (environmental context and resources); putting off undertaking the test (memory attention and decision processes); risk perception and fear of cancer (emotions). Enablers were: social influences from peers; goals and motivations.
Conclusions
Early results suggest an intervention comprising education, persuasion, modelling and enablement functions could increase completion of the home test.
Key messages
Community engagement and working with community leaders enhanced the success of recruitment. The TDF was a useful framework for identifying barriers to home bowel screening test by South Asians in the South East of England.

Abstract
INTRODUCTION It is important to collate the literature that has assessed dietary intake within military settings to establish which methods are commonly used and which are valid so that accurate nutrition recommendations can be made. This scoping review aims to identify which methods are typically used to assess dietary intake in military settings and which of these have been validated. This review also aims to provide a recommendation as to which method(s) should be used in military settings. METHODS This scoping review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Searches were conducted in PubMed, Web of Science and SPORTDiscus with the most recent search executed on 12th June 2020. Eligible studies had to report original data, assess and quantify dietary intake and have been published in peer-reviewed academic journals. The reporting bias was calculated for each study where possible. RESULTS Twenty-eight studies used a single method to assess dietary intake and seven studies used a combination of methods. The most commonly used methods were the gold standard food intake/waste method, Food Frequency Questionnaire (FFQ) or a food diary (FD). The only method to date that has been validated in military settings is weighed food records (WFR). CONCLUSIONS The food intake/waste method or WFR should be used where feasible. Where this is not practical the FFQ or FD should be considered with control measures applied. There is currently not sufficient evidence to state that using multiple methods together improves validity.

Abstract
BACKGROUND Physical activity can improve cognitive function of older adults, but the influence of sedentary behaviour on cognition is less clear. This systematic review investigated associations between sedentary behaviour and cognitive function in older adults without dementia, and possible mechanisms involved. METHODS Major databases were searched for studies in English between 01/01/1999 and 31/10/2019. The systematic review followed COSMOS-E guideline and a pre-registered protocol (CRD42019122229). Risk of bias was assessed using NICE Quality appraisal checklist. Findings were narratively synthesized and presented. FINDINGS Eighteen studies comprised of 13 cross-sectional and five longitudinal analyses (n = 40,228). Evidence suggested varied associations between varied sedentary behaviours and cognitive function in older adults. 50% of study analyses did not control for physical activity. 3/18 studies demonstrated associations between higher sedentary levels and lower levels of brain biomarkers, while 1/18 showed auto-regulatory effect in the left hippocampus. Conducting a meta-analysis was not justifiable due to considerable methodological, participant, outcome and exposure heterogeneity. CONCLUSION There is a lack of clarity about the overall and independent association between sedentary behaviour and cognition in older age. Underlying mechanisms are similar to physical activity and probably multi-modal. More studies with robust designs and methodology are needed to confirm effect of sedentary behaviour on cognition.

Abstract
Background Increasing resistance drives empirical use of less potent and previously reserved antibiotics, including for urinary tract infections (UTIs). Molecular profiling, without culture, might better guide early therapy. Objectives To explore the potential of AusDiagnostics multiplex tandem (MT) PCR UTI assays. Methods Two MT-PCR assays were developed successively, seeking 8 or 16 resistance genes. Amplification was tracked in real time, with melting temperatures used to confirm product identity. Assays were variously performed on: (i) extracted DNA; (ii) cultured bacteria; (iii) urine spiked with reference strains; and (iv) bacteria harvested from clinical urines. Results were compared with those from sequencing, real-time SybrGreen PCR or phenotypic susceptibility. Results Performance was similar irrespective of whether DNA, cultures or urines were used, with >90% sensitivity and specificity with respect to common β-lactamases, dfr genes and aminoglycoside resistance determinants except aadA1/A2/A3, for which carriage correlated poorly with streptomycin resistance. Fluoroquinolone-susceptible and -resistant Escherichia coli (but not other species) were distinguished by the melting temperatures of their gyrA PCR products. The time from urine to results was <3 h. Conclusions The MT-PCR assays rapidly identified resistance genes from Gram-negative bacteria in urines as well as from cultivated bacteria. Used directly on urines, this assay has the potential to guide early therapy.

Abstract
BACKGROUND Given the high burden and prevalence of depression, various guidelines underscore the role of healthcare providers in supplying advice on physical activity (PA) as a potential modifying factor influencing the incidence and severity of depressive symptoms in adults. We aimed to investigate the extent to which healthcare providers provide PA advice to adults with depressive symptoms in the US. METHODS Data on adults aged 20-64 years (n = 4971) in the National Health and Nutrition Examination Study between 2011 and 2016 were analysed. Depressive symptoms were assessed using the Patient Health Questionnaire and response options were categorised as "none or minimal", "mild", "moderate-severe". Receipt of PA advice from a healthcare provider was self-reported. We restricted our study sample to adults free from chronic diseases. RESULTS Higher odds of receiving advice to exercise were reported among adults with mild (OR = 1.7, 95% CI: 1.3-2.3) and moderate-severe depressive symptoms (OR = 1.7, 95% CI: 1.0-2.8). Furthermore, exercise advice was more commonly reported among adults who were overweight, obese, Hispanic, Asian, being insured with private insurance, with education higher than high school, and had access to a routine place for health care. LIMITATIONS Social and culutral aspects of overweight/obesity may prohibit generalizations. Cross sectional design does not allow for causal realtionships. CONCLUSIONS In the US, fewer than one in three adults experiencing symptoms of depression report having received exercise advice from a healthcare provider. Providing such advice may be a sustainable clinical strategy in reducing the incidence and severity of depression symptoms.
