Abstract
Limited data exist regarding the relationship between socioeconomic risk factors and failure to thrive (FTT). Using data from the National Health and Nutrition Examination Survey (NHANES) from years 1999 to 2014, we sought to determine whether there was a higher prevalence of underweight (<5th percentile weight-for-age [WFA], weight-for-length [WFL], or body mass index-for-age [BFA]), and, therefore, likely a higher risk of FTT, in US children <3 years with low household income or food insecurity compared with children without these factors. Among 7356 evaluated children, there were no significant differences in the prevalence of underweight by adjusted household income quintile, food security, household Women, Infants, and Children (WIC) status, or federal poverty income ratio. These findings do not support a link between low income or food security and underweight in children and, therefore, do not provide support for an association between low income or food security and FTT.

Abstract
Spin-valley locking is ubiquitous among transition metal dichalcogenides with local or global inversion asymmetry, in turn stabilizing properties such as Ising superconductivity, and opening routes towards 'valleytronics'. The underlying valley-spin splitting is set by spin-orbit coupling but can be tuned via the application of external magnetic fields or through proximity coupling. However, only modest changes have been realized to date. Here, we investigate the electronic structure of the V-intercalated transition metal dichalcogenide V1/3NbS2 using microscopic-area spatially resolved and angle-resolved photoemission spectroscopy. Our measurements and corresponding density functional theory calculations reveal that the bulk magnetic order induces a giant valley-selective Ising coupling exceeding 50 meV in the surface NbS2 layer, equivalent to application of a ~250 T magnetic field. This energy scale is of comparable magnitude to the intrinsic spin-orbit splittings, and indicates how coupling of local magnetic moments to itinerant states of a transition metal dichalcogenide monolayer provides a powerful route to controlling their valley-spin splittings.

Abstract
Abstract
Introduction
Pressure injury (PI) management is a challenge in dependent patients in acute care wards (ACW) despite standard care (regular pressure relief measures, incontinence management, debridement, optimisation of hydration and nutrition).
Method
A Pressure Injury Care Bundle (PICB), introduced by the Department of Geriatrics, enhanced standard care by diligent and regular interdisciplinary team monitoring of patients with PIs following transfer to Long Term Care (LTC) wards and thus may improve outcomes. The PICB was delivered by multiple PI Nurse Champions with education of all nurse assistants and medical staff into PI aetiology/management. Progress was monitored with weekly PI measurements/photography and Nurse Champion-lead team review of all PIs. Data are presented as mean+/-1SD. After 96+/-103 days in the ACW, the PICB was applied to 30 consecutive patients aged 80+/-14 years, (19(60 %) were female). All had stage 2-4 PIs (present in 25(83%) on admission to ACW). On transfer to LTC wards, all patients had severe physical dependency with a mean Charlson Comorbidity Index of 7+/-3, 27(90%) had palliative needs and 24(80%) were bedfast. Cognitive impairment was present in 22(68%) patients with 12(37%) dying due to advanced dementia. Patients were followed for 116+/-274 days.
Results
PI improvement by >2 stages occurred in 11(36%) patients after a mean of 103 days. Ulcers closed fully after 154+/-48 days in a further 15(50 %) patients. However, new ulcers emerged or preterminal (<21 days prior to death) deterioration occurred in 5(17%) patients, related to severe contractures, preterminal poor nutrition and sarcopenia with 16(54%) patients dying.
Conclusion
These results suggest that an intensive multimodal intervention involving best practice enhanced by PI Nurse Champions and delivered by educated staff with regular PI team progress reviews results in significant improvement/healing of PIs in severely dependent patients with palliative needs. Expansion of the PICB to other wards with prospective evaluation has been planned.

Abstract
Abstract
Introduction
Chronic subdural haematoma (CSDH) is a common neurosurgical pathology which is increasing in prevalence due to the ageing population. Predicting neurological outcome from defined metrics following surgery for CSDH is key to defining a neuroprognostic tool. Non-reactive pupils, due to coma, is recognised as an indicator of raised intracranial pressure (ICP) and poorer neurological outcome. There remains limited evidence defining its exact effect on outcome in patients with CSDH.
Method
Data from 1278 patients surgically managed for CSDH between 2009 and 2019 were retrospectively reviewed. Those with a GCS of 8 or less pre-operatively were identified (n = 77). These patient’s pupillary response at presentation, inpatient mortality, and Glasgow Outcome Score (GOS) on discharge were recorded from electronic and paper notes.
Results
8 patients (10.3%) had a non-reactive pupil at presentation. 4 patients with an unreactive pupil died as inpatients (50% mortality) versus 2 with bilaterally reactive pupils (2.8%) (p<0.01). Overall, only 1 survivor with non-reactive pupils had a good neurological outcome (GOS 4 or 5) meaning 7 or 87.5% had a poor neurological outcome (GOS 1-3) (p = 0.03). This compares to 35 patients or 50.7% having a poor neurological outcome in the bilaterally reactive pupil group. There is a statistically significant difference in mortality and morbidity in patients with a non-reactive pupil.
Conclusions
An unreactive pupil is a poor prognostic indicator of morbidity and mortality in patients presenting with CSDH.

Abstract
Abstract
Introduction
Seizure is a recognised complication of Chronic Subdural Haematoma (CSDH). Blood Type A has been indicated as a risk factor for developing postoperative seizures in Acute Subdural Haematoma (ASDH). However, to our knowledge there has not been a similar study to see if there is an association between blood type and seizure risk in CSDH.
Method
699 patients who had a CSDH surgically evacuated with burr holes between 2013 and 2019 were identified and their electronic and paper notes were retrospectively reviewed. Clinical information including their blood type and occurrence of postoperative seizure were recorded.
Results
26/699 patients overall had a postoperative seizure (3.7%). Blood type A had a higher overall number of seizures (4.3%, 13/301) than other blood types (3.4%,13/379) however this difference was not statistically significant (p = 0.22).
Conclusions
There is no convincing evidence that patients with blood type A have a higher risk of seizures after CSDH than patients with other blood types. Therefore, there is no reason to manage patients with blood type A differently regarding seizure prophylaxis.

Abstract
Abstract
Introduction
Chronic Subdural Haematoma (CSDH) is a common neurosurgical pathology. Neuroprognostication remains a challenge and evidence remain limited, particularly in patients presenting with a low GCS (8 or lower). Further clarification on neuroprognostication is important to inform surgical decision making.
Method
1278 patients who had CSDH surgically evacuated were retrospectively reviewed for GCS at presentation. 77 patients with GCS of 8 or less were detected. Mortality at discharge and 6 months, GCS, Glasgow Outcome Score (GOS) on discharge, discharge destination and other relevant clinical information were recorded from their paper and electronic notes.
Results
35 patients (45.4%) had a good neurological outcome (GOS 4 or 5). Inpatient mortality was 7.8% (n = 6). 6-month all-cause mortality was 20.7% (n = 16). Only 21.1% were discharged directly to their usual place of residence, with the remainder being discharged to local hospitals or rehabilitation units. Overall GCS (p = 0.003) and motor score (p = 0.013) at presentation was significantly associated with neurological outcome. Only overall GCS was associated with inpatient mortality (p = 0.037) but there was no association with mortality at 6 months (p = 0.603).
Conclusions
GCS of 8 or less in patients with CSDH is an important finding, with significant subsequent neurological morbidity and mortality. Although it is not the only prognostic indicator, a large number of patients had a good outcome despite this, indicating that intervention is not futile in all.

Abstract
Abstract
Aim
Efficient, succinct, and salient handover of current issues of surgical inpatients between doctors is an essential process which, if done ineffectively can contribute to patient harm. It was recognised that existing junior neurosurgical handover could be improved and using the Royal College of Surgeons’ and NICE guidelines for clinical handover we aimed to improve the existing handover system, improving doctor’s satisfaction with handover and patient safety.
Method
19 junior doctors on the SHO rota were surveyed to establish their perspective on the existing handover process. Based on this feedback, we redesigned handover combining national bodies’ guidance and local ideas. We resurveyed following these changes to measure improvement.
Results
Initial results showed only 36 % of junior doctors were satisfied with the existing handover procedure and only 50.5% felt the existing handover was safe. After these changes there was a 44% improvement in satisfaction with handover and a 24% improvement in the perceived safety of the handover process.
Conclusions
Handovers should be optimised to improve patient care and doctors working environment. We have improved our existing handover procedure increasing the perceived safety and doctor’s satisfaction of the handover process.

Abstract
Introduction Nosocomial transmission of SARS-CoV-2 has caused significant morbidity/mortality in the COVID-19 pandemic. Because patients auto-emit aerosols containing viable virus, these aerosols can be further propagated when patients undergo certain treatments including continuous positive airway pressure (PAP) therapy. This study aimed to assess the degree of viable virus propagated from mask leak in a PAP circuit. Methods Bacteriophage PhiX174 (108copies/mL) was nebulised into a custom PAP circuit. Mask leak was systematically varied to 0, 7, 21, 28 and 42 L/min at the mask interface. Plates containing Escherichia coli assessed the degree of viable virus settling on surfaces around the room. In order to contain virus spread a ventilated headboard and high efficiency particulate air (HEPA) filter was tested. Results Increasing mask leak was associated with virus contamination in a dose response manner (χ2= 58.24, df=4, p<0.001). Clinically relevant levels of leak (≥21 L/min) were associated with virus counts equivalent to using PAP with a standard vented mask. Viable viruses were recorded on all plates (up to 3.86m from source). A plastic hood with HEPA filtration significantly reduced viable viruses on all plates. HEPA exchange rates of 170 and 470m3/hr eradicated all evidence of virus contamination. Discussion Mask leak from PAP circuits may be a major source of environmental contamination and nosocomial spread of infectious respiratory diseases. Subclinical levels of leak should be treated as an infectious risk. Cheap and low-cost patient hoods with HEPA filtration are an effective countermeasure.

Abstract
Abstract
Introduction
External ventricular drains (EVDs) are commonly used in the management of acute hydrocephalus after subarachnoid haemorrhage (SAH). Infection is the most common complication. There remains controversy over whether frequent sampling is associated with increased risk of infection.
Method
Two cohorts of patients requiring EVD after SAH were retrospectively analysed for suspected and proven CSF infection. The first clinical cohort was of 50 consecutive patients with twice weekly sampling. The second group had alternate daily sampling as part of a prospective research study.
Results
Female to male ratio were (32:18) and (29:15) in clinical vs research group respectively. Average age of both groups was 59. Average length of treatment with EVD in both groups was 10 days. 16/50 (32%) patients had a suspected infection vs 13/44 (30%) and 8/50 (16%) had a proven infection compared to 6/44 (14%) in clinical and research groups, respectively. There was no statistically significant difference between the two groups (suspected infections p = 0.7 and proven infections p = 0.7)
Conclusions
Increased rates in CSF sampling in the research cohort did not result in higher rates of CSF infection. This suggests that rate of sampling, if done following a strict protocol, is not associated with increased risk of infection.

Abstract
Concentrations of dissolved organic carbon (DOC) have increased in lakes throughout North America and Europe over the last three decades. Recovery from acid deposition and climate change have both been postulated as the primary mechanisms for the increase in DOC. To provide a clearer insight into the mechanisms responsible for increasing DOC we evaluated changes in lake and peat porewater chemistry collected in an area of approximately 33,000 km2 surrounding Sudbury, Ontario, a region undergoing dramatic recovery from acidic deposition. DOC concentrations varied considerably among the 44 lakes and over time (samples annually from 1981 to 2018), but the Sens Slope value showed a strong increase in lake DOC concentration over time, at 0.05 mg/ L y-1 (p < 0.001) that was related to increasing pH [0.03 units y-1, p < 0.001] and decreasing lake SO4 concentration [-0.24 mg/ L y-1; p < 0.001], but showed no relationship with temperature or precipitation. Similar strong relationships between DOC and pH (positive) and SO4 (negative) were observed in 18 peatlands sampled in the region. In a spatial analysis of 82 lakes sampled in 2018, concentrations of DOC in lakes were highest in flatter catchments with a greater wetland area, suggesting that wetlands are a major source of DOC in lakes. Optical properties of DOC obtained from extracts of wetland and upland soils at 6 catchments could be distinguished, primarily due to upland litter extracts having distinct optical properties from mineral soils or wetland soils. Optical properties of DOC in lakes however were inconsistent with those measured in soil extracts indicating that they are not useful for distinguishing DOC sources in these lakes. A predictive model was developed to explain DOC trends within Sudbury lakes using a stepwise linear regression combined with hierarchical partitioning to confirm the most influential processes on DOC. Almost 50% of the variability in DOC change in the 44 lakes was explained by the magnitude in lake pH change, catchment size and catchment sparse tree cover showing that recovery from acidic deposition is overwhelmingly responsible for increasing DOC in Sudbury lakes.

Abstract
A 31-year-old immunocompetent, heterosexual man with no relevant medical history presented with 1 week of jaundice, abdominal pain, cough and headache. Examination revealed scleral icterus, right upper quadrant tenderness and hepatomegaly. Initial investigations revealed hyperbilirubinaemia and elevated transaminases. Serum studies were positive for antinuclear antibodies, antimitochondrial antibodies, and herpes simplex virus IgM. Despite being started on intravenous acyclovir, his bilirubin and transaminase levels continued to rise. He was subsequently tested for syphilis given his maculopapular rash on the soles of his feet and it returned positive. He improved clinically with the initiation of penicillin. In this case, we will discuss the presentation, diagnosis and treatment of syphilitic hepatitis.

Abstract
UNLABELLED Among 4238 cancer and 16,418 cancer-free individuals with incident major non-traumatic fractures (hip, clinical vertebral, forearm, humerus), post-fracture osteoporosis care was equally poor for both groups, whether assessed from bone mineral density (BMD) testing, initiation of osteoporosis therapy or either intervention (BMD testing and/or osteoporosis therapy). INTRODUCTION Most individuals sustaining a fracture do not undergo evaluation and/or treatment for osteoporosis. Cancer survivors are at increased risk for osteoporosis and fracture. Whether cancer survivors experience a similar post-fracture "care gap" is unclear. Using population-based databases, we assessed whether cancer patients are evaluated and/or treated for osteoporosis after a major fracture. METHODS From the Manitoba Cancer Registry, we identified cancer cases (first cancer diagnosis between 1987 and 2013) and cancer-free controls with incident major non-traumatic fractures (from provincial physician billing claims and hospitalization databases). The outcomes were performance of BMD testing (from the BMD Registry), initiation of osteoporosis therapy (from drug dispensation database) or either intervention (BMD testing and/or osteoporosis therapy) in the 12 months post-fracture. RESULTS There were 4238 cancer and 16,418 cancer-free individuals who sustained a fracture after the index date (cancer diagnosis) and were followed for at least 1 year post-fracture. Subsequent BMD testing was performed in 11.0% of cancer cases versus 11.5% non-cancer controls (P = 0.43), osteoporosis treatment in 22.9% cancer cases versus 21.8% non-cancer controls (P = 0.15), and either testing or treatment in 28.9% cancer cases versus 28.4% non-cancer controls (P = 0.53). Predictors of BMD testing and/or initiation of therapy were similar for non-cancer and cancer patients. Post-fracture interventions were consistently used more frequently among women, older patients (age 50 years or older), those who sustained fractures in a later calendar period, and (for treatment) after vertebral fracture. Cancer-specific variables (cancer type, years from cancer diagnosis to fracture, specialty of care provider) showed only weak and inconsistent effects. CONCLUSIONS A large care gap exists among cancer patients who sustain a fracture, similar to the general population, whereby the evaluation or treatment for osteoporosis is seldom conducted. Care maps may need to be developed for cancer populations to improve post-fracture care.

Abstract
Abstract
Introduction
Obstructive sleep apnea (OSA) is characterized by repetitive episodes of pharyngeal collapse. The genioglossus is a major upper airway dilator muscle thought to be important in OSA pathogenesis. Upper airway (UA) muscle training has reported benefits in some OSA patients. Our goal was to assess the effect of upper airway muscle training on OSA outcomes.
Methods
Sixty five patients with OSA (AHI>10/h) were divided in three subgroups: 1) Treated with auto-CPAP (n=21), 2) Previously failed or refused CPAP therapy (no treatment), (n=24), 3) Currently treated with an oral appliance who still have residual OSA (AHI>10/h), (n=20). All subjects were given a custom-made tongue strengthening device. Within each group we conducted a prospective, randomized, controlled study examining the effect of upper airway muscle training. In each subgroup, subjects were randomized to UA muscle training (volitional protrusion against resistance) or sham group (negligible resistance), with 1:1 ratio over 6 weeks of treatment (twice daily for 20 min/session). In the baseline and the final visit, subjects completed home sleep testing, questionnaires (ESS, PSQI), acoustic pharynogometry, Iowa Oral Performance Instrument (IOPI), and Psychomotor Vigilance Test (PVT).
Results
Results remain blinded; 33 patients received treatment Y and 32 patients received treatment Z. To date, we have not observed a main effect of treatment group on several measures of OSA severity. Some changes in subjective measures over time were observed but difficult to interpret until unblinding occurs.
Conclusion
Treatment of OSA using upper airway muscle training exercises requires further study. Whether muscle training is a viable approach for a definable subset of OSA patients remains unclear.

Abstract
Abstract
Lung cancer is the leading cause of cancer-related death in men in 87 countries and in women in 26 countries. The commensal microbiota lives on the epithelial barriers of the host and is vital for the health of the organism. Specific microbial species have been described to affect neoplastic pathology both at the gastrointestinal tract level and systematically in organs that are not normally associated with the gut microbiota. Studies have revealed the importance of the gut microbiota in the efficacy of anti-cancer therapies (chemo and immunotherapy) However, the role of lung microbiome in lung cancer remains largely unknown. We aimed to study the role of the lung microbiota during lung carcinogenesis progression in the context of p53/K-ras mutation and its impact on the tumor microenvironment. To further analyze the impact of the lung microbiota on lung cancer initiation, P53-Kras mutant germ-free mice will be colonized by intranasal instillation with bacteria identified in human lungs samples from lung cancer patients such as Variovorax paradoxus (V.paradoxus) and Acidovorax temperans (A.temperans) and the tumor burden will be calculated. Our data indicates Germ-free mice instilled with V. paradoxus trended towards an increase tumor burden compared to respective controls while A. temperans -associated germ-free mice seems to delay tumor growth. Germ-free mice, at 18 and 24 weeks post-Ad-Cre virus instillation, tends to have an increased tumor burden than their SPF counterparts. Also, changes in immune infiltrate were observed after flow cytometric analysis with preliminary data showing a decrease in CD45 positives cells the cells in mice instilled with V. paradoxus as well as an increase in Monocytes and Macrophages populations.

Abstract
BACKGROUND Many children in developed countries do not receive recommended vaccines on time. However, knowledge about factors related to timeliness remains limited. Quantifying the relative impact of parental attitudes compared with socio-demographic factors for delayed immunization would inform policy responses. METHODS Participants in the nationally representative Longitudinal Study of Australian Children were matched with their vaccination histories in the Australian Childhood Immunisation Register (N = 4,121). Information about the children and their families were collected in face-to-face interviews in 2003-2004. We considered whether children had completed the primary course for each recommended antigen due by 6 months old. Children were categorized as either fully immunized, delayed, or totally non-immunized. The outcome was examined using logistic regression. Population attributable fractions were estimated for key predictors. RESULTS Delayed immunization was significantly associated with indicators of social disadvantage as well as parental disagreement with immunization. Attributable fractions for delayed immunization included lone motherhood (3.8%; 95% confidence interval CI [0.8, 6.7]), larger family size (39.5%; 95% CI [31.2, 46.8]), residential mobility (3.3%; 95% CI [0.1, 6.5]), lack of private hospital insurance (9.4%; 95% CI [0.7, 17.3]), a medical condition in the child (2.0%; 95% CI [0.2, 3.9]), and parental disagreement with immunization (2.1%; 95% CI [0.3, 3.9]). CONCLUSIONS Parental attitudes accounted for a relatively small percentage of delayed infant immunization. In contrast, many children who did not receive vaccines on time were characterized by social disadvantage, especially larger family size. Researchers and policy-makers should consider how to make timely immunization easier for busy parents.

Abstract
Abstract
Chemotherapy induced toxicity severely affect the cancer survivors and lowers the quality of life. By 2020, there will be more than 18 million of cancer survivors all over the world. Majority of them might develop long term nephrotoxicity, ototoxicity and gut toxicity. In addition, chemotherapy may also facilitate the initiation and progression of cachexia. Recent studies have shown that gut microbiota modulates the efficacy of anti-cancer chemotherapy, however very limited knowledge is available regarding the role of gut microbiota in regulating systemic toxicity and cachexia. We hypothesized that gut microbiota modulates cisplatin induced systemic toxicity as well as cachexia. Four groups (n=10 in each group) of 6-8 weeks old C57B/6 mice were treated with cisplatin, cisplatin+antibiotics cocktails (ABX), ABX only and control. ABX cocktail contained primaxin, vancomycin and neomycin. This experiment was validated using C57B/6 germ free mice. We performed anti-p-γ-H2AX based toxicity assay for DNA damage. In addition, we performed immunohistochemistry for studying cachexia. H&E staining and DNA damage were assessed by light and super resolution confocal microscopy (Zeiss 880) and quantified by 3-D reconstruction using IMARIS. We also performed high content imaging to evaluate DNA damage in bone marrow and spleen. Body weight and kidney blood content were also analyzed to determine the degree of toxicity. Depletion of gut microbiota significantly reduced nephrotoxicity and gut toxicity. In addition, we found that depletion of gut microbiota prevents muscle and adipose tissue loss by down-regulating UCP-1and PGC-1α in adipose tissue and MURF-1 and Atrogin-1 in muscle. Experiments are confirmed by using Germ free mice. Our data suggest that modulation of gut microbiota may be utilized to reduce chemotherapy associated cachexia and systemic toxicity.

Abstract
X-ray backscatter imaging can be used for a wide range of imaging applications, in particular for industrial inspection and portal security. Currently, the application of this imaging technique to the detection of landmines is limited due to the surrounding sand or soil strongly attenuating the 10s to 100s of keV X-rays required for backscatter imaging. Here, we introduce a new approach involving a 140 MeV short-pulse (< 100 fs) electron beam generated by laser wakefield acceleration to probe the sample, which produces Bremsstrahlung X-rays within the sample enabling greater depths to be imaged. A variety of detector and scintillator configurations are examined, with the best time response seen from an absorptive coated BaF2 scintillator with a bandpass filter to remove the slow scintillation emission components. An X-ray backscatter image of an array of different density and atomic number items is demonstrated. The use of a compact laser wakefield accelerator to generate the electron source, combined with the rapid development of more compact, efficient and higher repetition rate high power laser systems will make this system feasible for applications in the field.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) infection continues to be a substantial global problem with significant associated morbidity and mortality. This review summarises the discussions that took place at the 4th MRSA Consensus Conference in relation to the current treatment options for serious MRSA infections and how to optimise whichever therapy is embarked upon. It highlights the many challenges faced by both the laboratory and clinicians in the diagnosis and treatment of MRSA infections.

Abstract
The Large Underground Xenon (LUX) experiment is a dual-phase xenon time-projection chamber operating at the Sanford Underground Research Facility (Lead, South Dakota). The LUX cryostat was filled for the first time in the underground laboratory in February 2013. We report results of the first WIMP search data set, taken during the period from April to August 2013, presenting the analysis of 85.3 live days of data with a fiducial volume of 118 kg. A profile-likelihood analysis technique shows our data to be consistent with the background-only hypothesis, allowing 90% confidence limits to be set on spin-independent WIMP-nucleon elastic scattering with a minimum upper limit on the cross section of 7.6 × 10(-46) cm(2) at a WIMP mass of 33 GeV/c(2). We find that the LUX data are in disagreement with low-mass WIMP signal interpretations of the results from several recent direct detection experiments.

Abstract
This paper focuses on antimicrobial stewardshipin human healthcare, and some concepts possibly transferable to veterinary medicine. Antimicrobial stewardship is a multidisciplinary effort to reduce antimicrobial resistance in human pathogens, when future drug development is dwindling. These strategies encourage healthcare staff to use antimicrobials prudently and, when needed, for as short a duration and with as narrow a spectrum as possible. Various methods are involved in stewardship within the healthcare setting, often implemented simultaneously, which sometimes makes evaluation of specific measures difficult. All healthcare workers must accept responsibility for stewardship, although the role of infectious diseases physicians, microbiologists, pharmacists and infection control practitioners is crucial, as are appropriate surveillance systems and information technology. Support from management and government is also beneficial. Considering the frequent use of antimicrobials in animals, it would seem sensible to apply a similarly critical approach to conserve the efficacy of the antimicrobials still available, now and in the future.

Abstract
Hepatic stellate cells (HSCs) play an important role in several (patho)physiologic conditions in the liver. In response to chronic injury, HSCs are activated and change from quiescent to myofibroblast-like cells with contractile properties. This shift in phenotype is accompanied by a change in expression of intermediate filament (IF) proteins. HSCs express a broad, but variable spectrum of IF proteins. In muscle, syncoilin was identified as an alpha-dystrobrevin binding protein with sequence homology to IF proteins. We investigated the expression of syncoilin in mouse and human HSCs. Syncoilin expression in isolated and cultured HSCs was studied by qPCR, Western blotting, and fluorescence immunocytochemistry. Syncoilin expression was also evaluated in other primary liver cell types and in in vivo-activated HSCs as well as total liver samples from fibrotic mice and cirrhotic patients. Syncoilin mRNA was present in human and mouse HSCs and was highly expressed in in vitro- and in vivo-activated HSCs. Syncoilin protein was strongly upregulated during in vitro activation of HSCs and undetectable in hepatocytes and liver sinusoidal endothelial cells. Syncoilin mRNA levels were elevated in both CCl4- and common bile duct ligation-treated mice. Syncoilin immunocytochemistry revealed filamentous staining in activated mouse HSCs that partially colocalized with α-smooth muscle actin, β-actin, desmin, and α-tubulin. We show that in the liver, syncoilin is predominantly expressed by activated HSCs and displays very low-expression levels in other liver cell types, making it a good marker of activated HSCs. During in vitro activation of mouse HSCs, syncoilin is able to form filamentous structures or at least to closely interact with existing cellular filaments.

Abstract
Meticillin-resistant Staphylococcus aureus causes an evolving clinical presentation of pneumonia. Health-care-acquired infection differs from community-associated disease, with important implications for treatment. Current antibiotics are less than ideal, and broader management strategies are crucial to prevent complacency.
