Published: November 2021

Abstract
Background
Pathogens of the genus Phytophthora are the etiological agents of many devastating diseases in several high-value crops and forestry species such as potato, tomato, cocoa, and oak, among many others. Phytophthora betacei is a recently described species that causes late blight almost exclusively in tree tomatoes, and it is closely related to Phytophthora infestans that causes the disease in potato crops and other Solanaceae. This study reports the assembly and annotation of the genomes of P. betacei P8084, the first of its species, and P. infestans RC1-10, a Colombian strain from the EC-1 lineage, using long-read SMRT sequencing technology.

Results
Our results show that P. betacei has the largest sequenced genome size of the Phytophthora genus so far with 270 Mb. A moderate transposable element invasion and a whole genome duplication likely explain its genome size expansion when compared to P. infestans, whereas P. infestans RC1-10 has expanded its genome under the activity of transposable elements. The high diversity and abundance (in terms of copy number) of classified and unclassified transposable elements in P. infestans RC1-10 relative to P. betacei bears testimony of the power of long-read technologies to discover novel repetitive elements in the genomes of organisms. Our data also provides support for the phylogenetic placement of P. betacei as a standalone species and as a sister group of P. infestans. Finally, we found no evidence to support the idea that the genome of P. betacei P8084 follows the same gene-dense/gense-sparse architecture proposed for P. infestans and other filamentous plant pathogens.

Conclusions
This study provides the first genome-wide picture of P. betacei and expands the genomic resources available for P. infestans. This is a contribution towards the understanding of the genome biology and evolutionary history of Phytophthora species belonging to the subclade 1c.

Abstract
Background
An airway-associated fire in an operating room can have devastating consequences for patients. Breathing circuit warmers (BCWs) are widely used to provide heated and humidified anesthetic gases and eventually prevent hypothermia during general anesthesia. Herein, we describe a case of a BCW-related airway fire.

Case presentation
In this case, an electrical short within a BCW wire caused a fire inside the circuit. Simultaneously, the fire was extinguished, ventilation was stopped, and the endotracheal tube was disconnected from the BCW. The patient was exposed to the fire for less than 10 s, resulting in burns to the trachea and bronchi. Immediately after airway burn, bronchoscopy showed no edema or narrowing except for soot in the trachea and both main bronchus. After the inhalation burn event, prophylactic antibiotics, bronchodilator, mucolytics nebulizer, and corticosteroid nebulizer were started. On bronchoscopy 3 days after the inhalation burn, mucosal erythematous edema was observed and the inflammatory reaction worsened. The inflammatory reaction showed aggravation for up to 2 weeks, and then gradually recovered, and the epithelium and mucous membrane of the upper respiratory tract returned to normal after 4 weeks. Eventually, the patient recovered without long-term complications and was successfully discharged.

Conclusions
This is the first report of a fire caused by BCW. We wanted to share our experience of how we responded to an airway-related fire in an OR and treated the patient. It cannot be overemphasized that the electrical medical appliance associated with the airways are fatal to the patient in the event of a fire, so caution should always be exercised.

Published: November 2021

Abstract
Background
Early and timely fluid treatment or resuscitation are the basic measures for the active treatment of sepsis. Our aim is to further explore the relationship between fluid balance and prognosis in patients with sepsis on a daily basis for 5 days.

Methods
Sepsis patients in eICU Collaborative Research Database were divided into the negative balance group (NB/−) and the positive balance group (PB/+) according to daily fluid balance. The primary outcome was in-hospital mortality. Survival differences between the groups were analyzed by using Cox regression. Then dose-response relationship between fluid balance and in-hospital mortality was studied using restricted cubic splines (RCSs). Furthermore, patients with fluid balance data for the previous three consecutive days were selected and divided into eight groups (“+/+/+”, “+/+/−”, “+/ −/−”, “+/ −/+”, “−/ −/−”, “−/ −/+”, “−/+/+”, and “−/+/−”). Kaplan–Meier curves and Cox regression were used to show the survival difference between groups.

Results
Our study, which included 19,557 patients in a multicenter database, showed that positive fluid balances on days 1, 2, and 3 after sepsis diagnosis were associated with poor prognosis with the HRs of 1.29 (1.20,1.40), 1.13 (1.01,1.27), and 1.25 (1.08,1.44), respectively, while the fluid balance on days 4 and 5 had no effect on the primary outcome. Then RCSs showed an overall trend that the risk of in-hospital mortality on days 1, 2, and 3 increased with increasing fluid balance. For three consecutive days of fluid balance, we studied 9205 patients and Kaplan–Meier curves revealed survival differences among patients in the eight groups. The cox model demonstrated that compared with the “+/+/+” group, the “+/ −/−”, “−/ −/−”, “−/ −/+”, “−/+/+”, and “−/+/−” groups had a lower risk of in-hospital mortality, with HRs of 0.65 (0.45,0.93), 0.72 (0.60,0.86), 0.63 (0.43,0.93), 0.69 (0.48,0.98), and 0.63 (0.42,0.96), respectively.

Conclusions
In patients with sepsis, positive fluid balance on days 1, 2, and 3 was associated with adverse outcomes. For patients with fluid balance for three consecutive days, the “+/−/−”, “−/ −/−”, “−/−/+”, “−/+/+”, and “−/+/−” groups were less likely to die in hospital than the “+/+/+” group.
Contrast-induced encephalopathy mimicking stroke after a second cerebral DSA: an unusual case report
Authors: Li Jiaying , Qi Guanshu , Zhang Huani , Chen Gang , Wang Shuting , Yan Minli , Sun Zhichao 
Published: November 2021

Abstract
Background
Contrast-induced encephalopathy (CIE) is a rare complication of the angiography process. CIE may mimic stroke symptoms clinically and subarachnoid hemorrhage radiologically. Previous CIE cases occurred after the initial digital subtraction angiography (DSA) scan. Here, we encountered an unusual case of CIE mimicking a stroke with an internal carotid artery (ICA) aneurysm and ipsilateral ICA stenosis that occurred after a second DSA procedure.

Case presentation
A 77-year-old female with a history of hypertension and coronary heart disease underwent two cerebral DSA procedures over 1 week. She was given the same nonionic and iso-osmolar Visipaque agent (smaller than 200 ml) for both procedures. However, neurological complications only occurred after the second DSA procedure. On the first diagnostic cerebral DSA, she was diagnosed with an intracranial aneurysm of the left ICA with moderate stenosis (approximately 50%) in the initial part of the ipsilateral ICA. However, after the second aneurysm embolization procedure by DSA, she developed right hemiplegia, aphasia, and epilepsy, mimicking left middle cerebral artery occlusion. An emergency CT showed a diffuse hyperdensity in the left subarachnoid space, mimicking SAH. MRI demonstrated that the lesion was hyperintense on T2WI, FLAIR imaging, and DWI but was normal on ADC mapping. On postoperative Day 6, her neurologic deficits had completely resolved after initial fluid restriction, corticosteroid treatment, and rehydration.

Conclusion
This case indicates that clinicians should consider the occurrence of CIE following any angiography procedure, even if the initial cerebral DSA procedure is successful and without complications.
The association between obesity and quality of life: a retrospective analysis of a large-scale population-based cohort study
Authors: Stephenson J. , Smith C. M. , Kearns B. , Haywood A. , Bissell P. 
Published: November 2021

Abstract
Background
The relationship between obesity and health-related quality of life (HRQoL) may be confounded by factors such as multimorbidity. The aim of the study was to explore this relationship, controlling for long-term conditions and other health, lifestyle and demographic factors in a general adult population. There was specific interest in the impact of high weight status, measured by body mass index (BMI) levels (obesity, morbid obesity) compared with individuals of normal weight.

Methods
Health, lifestyle and demographic data were collected from 64,631 individuals aged 16 years and over registered in the Yorkshire Health Study; a long-term cohort study. Data were collected in 2 waves: from patients attending GP surgeries in the South Yorkshire region; and using online recruitment across the entire Yorkshire and Humber area. Univariable and multivariable regression methods were utilised to identify factors associated with HRQoL as measured by the EQ-5D summary score. Long-term conditions were tested as both covariates and mediating factors on the causal pathway between obesity and HRQoL.

Results
Increasing levels of obesity are associated with reduced HRQoL, although this difference is negligible between those of normal weight and those who are overweight. Individuals with obesity and morbid obesity score 4.9 and 11.3 percentage points less on the EQ-5D summary scale respectively than those of normal weight. Concurrent physical, and particularly mental health-related long-term conditions are substantively related to HRQoL: those with 3 or more reported mental or physical health conditions score 29.8 and 14.6 percentage points less on the EQ-5D summary scale respectively than those with fewer conditions. Long-term conditions can be conceptualised as lying on the causal path between obesity and HRQoL, but there is weak evidence for a partial mediating relationship only.

Conclusions
To conclude, in agreement with the established literature we have found a clear inverse relationship between increasing weight status and decreasing HRQoL and confirmed the mediating role of long-term conditions in the reduction of HRQoL in people with obesity. Nevertheless, a high BMI remains independently related to HRQoL, suggesting that ‘healthy people with obesity’ may be in transition to an unhealthy future.

Abstract
Background
Cervical cancer (CC) is the cancer with the most incidents and the leading cause of cancer mortality among women in South Africa. CC screening is one of the most cost-effective control approaches for the disease burden. This study assessed the determinants and individual-level indicators of cervical cancer screening uptake among women of reproductive age in South Africa.

Methods
We analyzed data from the 2016 South Africa Demographic Health Survey. Our analysis focused on 5903 women (15–49 years). We conducted Chi-square test for bivariate analysis, and multivariate binary logistics regression was used to analyze independent association between individual-level factors and women who have had Pap smear testing. Statistical significance was set at p < 0.05.

Results
The mean age at cervical cancer screening uptake among women in South Africa was 40.8 years (SD 18.6, range 15–95 years). A majority of the women (39.3%) were aged 45 years and above and 54.6% of them resides in urban settlements. About 35.4% of women (n = 2098) have had a Pap smear test, with 66.5% of them who had a Pap smear test resides in Western Cape province. The proportion of women who had a Pap smear test was significantly higher among those with higher educational attainment (68.7%, p = 0.000), in the rich wealth index (50.1%, p = 0.000), and those with health insurance cover (60.3%, p = 0.000). Pap smear testing was found to be more prevalent among women aged 45+ years, were in the white population group, had higher education, were divorced, and had health insurance cover. The predominance of Pap smear test was 14% higher among women who are working in the professional/formal sector (AOR; 1.38, 95% CI; 1.14–1.69). The uptake of Pap smear test was also higher among women aged 35–44 years.

Conclusions
The prevalence of cervical cancer uptake is substantially low among women aged 15–24 years in South Africa and shows a degree of between-provinces differences. Therefore, heath educational interventions aimed at increasing the uptake of cervical cancer screening services in South Africa are critically needed.
Satisfying medical and rehabilitation needs positively influences returning to work after a work-related injury: an analysis of national panel data from 2018 to 2019
Authors: Bae Suk Won , Lee Min-Yong , Park Shin Who , Lee Gangpyo , Leigh Ja-Ho 
Published: November 2021

Abstract
Background
This study examined how meeting the medical needs of injured workers after initial treatment may affect their return to work, using data from the Panel Study of Workers’ Compensation Insurance.

Methods
This study was designed as a longitudinal study, which used data from the second-year, follow-up survey conducted in the secondary cohort of the Panel Study of Workers’ Compensation Insurance. The odds ratio (OR) and 95% confidence interval were estimated through binomial and multinomial logistic regression analyses to examine the effects of unmet medical needs on workers’ return to original work and return to work overall (including reemployment).

Results
The returned to original work OR of workers whose rehabilitation needs were met was 1.35 (1.12–1.63) while the return to work OR was 1.20 (1.03–1.41). The returned to original work OR of workers whose medical needs were met was 1.64 (1.18–2.27) while the return to work OR was 1.39 (1.07–1.80). In terms of disability rating, the return to work ORs of workers with mild disabilities whose medical/rehabilitation needs were not met and those of workers without disabilities were 1.71 (1.17–2.49) and 1.97 (1.27–3.08), respectively. In the case of regular/temporary workers, the returned-to-work ORs of workers whose medical/rehabilitation needs were not met were 1.54 (1.12–2.13) and 1.27 (1.03–1.56), respectively.

Conclusions
For workers who sustained work-related injuries, providing medical accessibility and meeting rehabilitation needs were found to be important predictors of return to work after initial treatment.
Tweeting about twenty: an analysis of interest, public sentiments and opinion about 20mph speed restrictions in two UK cities
Authors: Semwal Tushar , Milton Karen , Jepson Ruth , Kelly Michael P. 
Published: November 2021

Abstract
Background
Twenty miles per hour (20mph) speed limits (equivalent to roughly 30kmh) have become part of public health policies to reduce urban road collisions and casualties, especially in Western countries. Public opinion plays a crucial role in opposition to and acceptance of policies that are advocated for improving public health. Twenty miles per hour speed limit policies were implemented in Edinburgh and Belfast from 2016 to 2018. In this paper, we extract public opinion and sentiments expressed about the new 20mph speed limits in those cities using publicly available Twitter data.

Methods
We analysed public sentiments from Twitter data and classified the public comments in plain English into the categories ‘positive’, ‘neutral’, and ‘negative’. We also explored the frequency and sources of the tweets.

Results
The total volume of tweets was higher for Edinburgh than for Belfast, but the volume of tweets followed a similar pattern, peaking around 2016, which is when the schemes were implemented. Overall, the tone of the tweets was positive or neutral towards the implementation of the speed limit policies. This finding was surprising as there is a perception among policymakers that there would have been public backlash against these sorts of policy changes. The commonly used hashtags focused largely on road safety and other potential benefits, for example to air pollution.

Conclusions
Overall, public attitudes towards the policies were positive, thus policymakers should be less anxious about potential public backlash when considering the scale-up of 20mph speed restrictions.
Molecular characterization of NDM-1-producing Pseudomonas aeruginosa isolates from hospitalized patients in Iran
Authors: Shahin Mojtaba , Ahmadi Ali 
Published: November 2021

Abstract
Background
The emergence of carbapenem-resistant Pseudomonas aeruginosa is one of the most important challenges in a healthcare setting. The aim of this study is double-locus sequence typing (DLST) typing of blaNDM-1 positive P. aeruginosa isolates.

Methods
Twenty-nine blaNDM-1 positive isolates were collected during three years of study from different cities in Iran. Modified hodge test (MHT), double-disk synergy test (DDST) and double-disk potentiation test (DDPT) was performed for detection of carbapenemase and metallo-beta-lactamase (MBL) producing blaNDM-1 positive P. aeruginosa isolates. The antibiotic resistance genes were considered by PCR method. Clonal relationship of blaNDM-1 positive was also characterized using DLST method.

Results
Antibiotic susceptibility pattern showed that all isolates were resistant to imipenem and ertapenem. DDST and DDPT revealed that 15/29 (51.8%) and 26 (89.7%) of blaNDM-1 positive isolates were MBL producing isolates, respectively. The presence of blaOXA-10,blaVIM-2, blaIMP-1 and blaSPM genes were detected in 86.2%, 41.4%, 34.5% and 3.5% isolates, respectively. DLST typing results revealed the main cluster were DLST 25-11 with 13 infected or colonized patients.

Conclusions
The presence of blaNDM-1 gene with other MBLs encoding genes in P. aeruginosa is a potential challenge in the treatment of microorganism infections. DLST showed partial diversity among 29 blaNDM-1 positive isolates.

Abstract
Background
Multiple sclerosis (MS) is a chronic autoimmune disease driven by sustained inflammation in the central nervous system. One of the pathological hallmarks of MS is extensive free radical production. However, the subsequent generation, potential pathological role, and detoxification of different lipid peroxidation-derived reactive carbonyl species during neuroinflammation are unclear, as are the therapeutic benefits of carbonyl quenchers. Here, we investigated the reactive carbonyl acrolein and (the therapeutic effect of) acrolein quenching by carnosine during neuroinflammation.

Methods
The abundance and localization of acrolein was investigated in inflammatory lesions of MS patients and experimental autoimmune encephalomyelitis (EAE) mice. In addition, we analysed carnosine levels and acrolein quenching by endogenous and exogenous carnosine in EAE. Finally, the therapeutic effect of exogenous carnosine was assessed in vivo (EAE) and in vitro (primary mouse microglia, macrophages, astrocytes).

Results
Acrolein was substantially increased in inflammatory lesions of MS patients and EAE mice. Levels of the dipeptide carnosine (β-alanyl-l-histidine), an endogenous carbonyl quencher particularly reactive towards acrolein, and the carnosine-acrolein adduct (carnosine-propanal) were ~ twofold lower within EAE spinal cord tissue. Oral carnosine treatment augmented spinal cord carnosine levels (up to > tenfold), increased carnosine-acrolein quenching, reduced acrolein-protein adduct formation, suppressed inflammatory activity, and alleviated clinical disease severity in EAE. In vivo and in vitro studies indicate that pro-inflammatory microglia/macrophages generate acrolein, which can be efficiently quenched by increasing carnosine availability, resulting in suppressed inflammatory activity. Other properties of carnosine (antioxidant, nitric oxide scavenging) may also contribute to the therapeutic effects.

Conclusions
Our results identify carbonyl (particularly acrolein) quenching by carnosine as a therapeutic strategy to counter inflammation and macromolecular damage in MS.
The balance between AIM2-associated inflammation and autophagy: the role of CHMP2A in brain injury after cardiac arrest
Authors: Shao Rongjiao , Wang Xintao , Xu Tianhua , Xia Yiyang , Cui Derong 
Published: November 2021

AbstractBackgroundActivation of the absent in melanoma 2 (AIM2) inflammasome and impaired autophagosome clearance in neurons contribute significantly to cardiac arrest and return of spontaneous circulation (CA-ROSC) injury, while the mechanism by which the AIM2 inflammasome is regulated and relationship between the processes remain poorly understood. Recently, charged multivesicular body protein 2A (CHMP2A), a subunit of endosomal sorting complex required for transport (ESCRT), was shown to regulate phagophore closure, and its depletion led to the accumulation of autophagosomes and induced cell death. Here, we investigated whether CHMP2A-mediated autophagy was an underlying mechanism of AIM2-associated inflammation after CA-ROSC and explored the potential link between the AIM2 inflammasome and autophagy under ischemic conditions.MethodsAIM2 inflammasome activation and autophagic flux in the cortex were assessed in the CA-ROSC rat model. We injected LV-Vector or LV-CHMP2A virus into the motor cortex with stereotaxic coordinates and divided the rats into four groups: Sham, CA, CA+LV-Vector, and CA+LV-CHMP2A. Neurologic deficit scores (NDSs), balance beam tests, histopathological injury of the brain, and expression of the AIM2 inflammasome and proinflammatory cytokines were analyzed.ResultsAIM2 inflammasome activation and increased interleukin 1 beta (IL-1β) and IL-18 release were concurrent with reduced levels of CHMP2A-induced autophagy in CA-ROSC rat neurons. In addition, silencing CHMP2A resulted in autophagosome accumulation and decreased autophagic degradation of the AIM2 inflammasome. In parallel, a reduction in AIM2 contributed to autophagy activation and mitigated oxygen–glucose deprivation and reperfusion (OGD-Rep)-induced inflammation. Notably, CHMP2A overexpression in the cortex hindered neuroinflammation, protected against ischemic brain damage, and improved neurologic outcomes after CA.ConclusionsOur results support a potential link between autophagy and AIM2 signaling, and targeting CHMP2A may provide new insights into neuroinflammation in the early phase during CA-ROSC.
