001) and marA (P=.009) were significantly higher in the tigecycline-resistant group than in the tigecycline-intermediate and tigecycline-susceptible groups. Increased expression of acrB was associated with marA expression (r=0.59, P=.013).
We found that the activated MarA-induced overexpression of AcrAB efflux pump plays an important role in the emergence of tigecycline resistance in CRKP isolates.

Due to limitations of coronary angiography (CA), the diagnosis of ostial LM stenosis solely based on CA may result in underdiagnosis of such lesions. Therefore, additional testing is often needed either by pressure wire or intravascular ultrasound (IVUS) to make appropriate diagnosis. We, hereby, present a case of left main ostial stenosis in a 56-year-old male that was missed on multiple coronary angiograms, and highlights many of the considerations in the diagnosis of LM disease.
The Ages and Stages Questionnaire-Talking about Raising Aboriginal Kids (ASQ-TRAK) culturally adapted developmental screening tool is widely used in Australian Aboriginal communities. However, there has been limited exploration of the tool's acceptability to caregivers. The aim of the study is to determine the acceptability of the ASQ-TRAK developmental screening tool to caregivers of Aboriginal children in urban, regional and remote South Australia.
Caregivers of Aboriginal children completed a survey regarding acceptability of the ASQ-TRAK. Convenience samples of caregivers were invited to a telephone interview.
Ninety-two caregivers completed the survey (96% response). Acceptability (92%) and caregiver satisfaction (73%) were high. Families perceived the screen as easy to use and understand, strengths-based and providing valuable information about their child's development.
The ASQ-TRAK tool was highly acceptable to caregivers in Aboriginal communities in South Australia. The study highlights the importance of culturally safe practice and supports ASQ-TRAK implementation. Broader use and further evaluation of the ASQ-TRAK in Aboriginal communities needs consideration.

With the advent of new direct antiviral agents (DAAs) HCV micro-elimination in prison setting became a feasible strategy. We assessed the impact of an intervention for HCV testing and treatment in 2017 and 2018 in a jail (San Vittore,SV) and a prison for sentenced individuals (Opera,OP). A dedicated protocol was applied and implemented over the two years. We collected data on demographics, HCV testing and treatment on all inmates present on 31 October 2017 and 2018. In the two facilities, there were 2,366 and 2,369 inmates in 2017 and 2018 respectively; the majority were men (95.6%; 96.4%) and Italians (57.0%; 61.9%) with a median age of 41 years. Prevalence of lifetime reported drug use remained high (46.5%; 44.2%). HCV screening coverage was 89% in both years, while HCV RNA test coverage increased (90.6%; 99.0%). HCV seroprevalence remained stable (10.1%; 9.2%). In 2017 among inmates with HCV chronic infection 90 (42.4%) individuals had started DAAs treatment and 106 (54.6%) in 2018; of whom 38 (17.9%) and 74 (38.1%) achieved the SVR. The viremic pool decreased significantly over time (SV,24.4%; 15.4%;OP, 16.1%; less then 1%). Among inmates with HCV-positive serology in 2018, 121 (81.0%) were never linked to care before incarceration. Our study showed how a targeted and well-implemented HCV test-and-treat intervention in prison was feasible and effective in achieving micro-elimination. Viral hepatitis elimination agenda may help drawing interest onto this neglected population and bringing prison health higher up in the global public health agenda.
Molecular assays based on reverse transcription-polymerase chain reaction (RT-PCR) provide reliable results for the detection of respiratory pathogens, although diagnostic agreement varies. This study determined the agreement between the RT-PCR assays (Xpert
Flu/RSV vs Allplex
RP1) in detecting influenza A, influenza B, and respiratory syncytial viruses (RSVs) in clinical practice.
We retrospectively identified 914 patient encounters where testing with both Xpert
Flu/RSV and Allplex
RP1 was undertaken between October 2015 and September 2019 in seven hospitals across New South Wales, Australia. The diagnostic agreement of the two assays was evaluated using positive percent agreement, negative percent agreement, and prevalence and bias-adjusted kappa.
The positive percent agreement was 95.1% for influenza A, 87.5% for influenza B, and 77.8% for RSV. The negative percent agreement was 99.4% for influenza A, 99.9% for influenza B, and 100% for RSV. The prevalence and bias-adjusted kappa was 0.98 for influenza A, 0.99 for influenza B, and 0.97 for RSV. In a sensitivity analysis, the positive percent agreement values were significantly higher during the non-influenza season than the influenza season for influenza B and RSV.
The Xpert
Flu/RSV and Allplex
RP1 demonstrated a high diagnostic agreement for all three viruses assessed. The seasonal variation in the positive percent agreement of the two assays for influenza B and RSV may have been due to lower numbers assessed, variability in the virology of infections outside the peak season, or changes in the physiology of the infected host in different seasons.

Preliminary data from different cohorts of small sample size or with short follow-up indicate poorer prognosis in people with obesity compared with other patients. This study aims to precisely describe the strength of association between obesity in patients hospitalized with coronavirus disease 2019 (COVID-19) and mortality and to clarify the risk according to usual cardiometabolic risk factors in a large cohort.
This is a prospective cohort study including 5,795 patients aged 18 to 79 years hospitalized from February 1 to April 30, 2020, in the Paris area, with confirmed infection by severe acute respiratory syndrome coronavirus 2. Adjusted regression models were used to estimate the odds ratios (ORs) and 95% CIs for the mortality rate at 30 days across BMI classes, without and with imputation for missing BMI values.
Eight hundred ninety-one deaths had occurred at 30 days. Mortality was significantly raised in people with obesity, with the following ORs for BMI of 30 to 35 kg/m
, 35 to 40 kg/m
, and >40 kg/m
1.89 (95% CI 1.45-2.47), 2.79 (95% CI 1.95-3.97), and 2.55 (95% CI 1.62-3.95), respectively (18.5-25 kg/m
was used as the reference class). This increase holds for all age classes.
Obesity doubles mortality in patients hospitalized with COVID-19.

We aimed to develop a clinical prediction rule for risk stratification to avoid CT head imaging in older adult patients with minor head injury, named Computed Tomography of the Head for the patients at Advanced age (CTHEAD). This was a single-center observational study in Japan that used retrospective chart review data to service a prediction rule that was prospectively validated. Patients aged ≥ 65 years who presented to our emergency department with a chief complaint of head trauma and a Glasgow Coma Scale (GCS) of ≥13 were eligible. Patients were excluded if they had GCS score less then 13, anticoagulant therapy, focal neurologic symptoms, posttraumatic seizures, penetrating injury, evident depressed fracture, unknown mechanism, or CT not undertaken. The primary outcome was acute traumatic lesion on head CT. We screened 1,494 patients; 538 were included in the derivation cohort, ande amnesia. link2 External validation of this rule is needed.We show the synthesis of a redox-active quinone, 2-methoxy-1,4-hydroquinone (MHQ), from a bio-based feedstock and its suitability as electrolyte in aqueous redox flow batteries. We identified semiquinone intermediates at insufficiently low pH and quinoid radicals as responsible for decomposition of MHQ under electrochemical conditions. Both can be avoided and/or stabilized, respectively, using H 3 PO 4 electrolyte, allowing for reversible cycling in a redox flow battery for hundreds of cycles.
The 2019 novel coronavirus (severe acute respiratory syndrome coronavirus 2) is causing cases of severe pneumonia. Lung ultrasound (LUS) could be a useful tool for physicians detecting a bilateral heterogeneous patchy distribution of pathologic findings in a symptomatic suggestive context. The aim of this study was to focus on the implications of limiting LUS examinations to specific regions of the chest.
Patients were evaluated with a standard sequence of LUS scans in 14 anatomic areas. A scoring system of LUS findings was reported, ranging from 0 to 3 (worst score, 3). The scores reported on anterior, lateral, and posterior landmarks were analyzed separately and compared with each other and with the global findings.
Thirty-eight patients were enrolled. A higher prevalence of score 0 was observed in the anterior region (44.08%). On the contrary, 21.05% of posterior regions and 13.62% of lateral regions were evaluated as score 3, whereas only 5.92% of anterior regions were classified as score 3. Findings from chest computed tomography performed in 16 patients with coronavirus disease 2019 correlated with and matched the distribution of findings from LUS.
To assess the quantity and severity of lung disease, a comprehensive LUS examination is recommended. Omitting areas of the chest misses involved lung.

Gene expression analysis of the conceptus and maternal reproductive tissues is a favourable method to assess the embryonic maternal interaction. The reliability of the commonly used method reverse transcription-quantitative polymerase chain reaction (RT-qPCR) depends on proper normalization to stable reference genes (RGs). link3 The objective of this study was to determine the expression stability of 10 potential RGs in maternal reproductive tissues and foetal tissues, and to analyse the effect of RG selection on the calculation of the relative expression of target genes. The expression stability of 10 potential RGs was analysed in eight different tissues from three pregnant dairy cows. Three programs-GeNorm, NormFinder and Bestkeeper-were used to identify the best RGs. According to all three programs, the most stable RG was CNOT11, whereas the least stable RGs were GAPDH and HPRT1.
