Tin filter-based spectral shaping has been used for low-dose and ultra-low-dose computed tomography (CT) in several body parts. However, studies of shoulder CT arthrography with spectral shaping are limited.
To investigate image quality and radiation dose of shoulder CT arthrography with tin filter-based spectral shaping at 100 kV (Sn 100 kV) and 140 kV (Sn 140 kV) in comparison with the conventional protocol.
Ninety-nine shoulder CT arthrographies with protocols of Sn 100 kV (n = 32), Sn 140 kV (n = 25), and conventional 120 kV (n = 42) were retrospectively evaluated. Qualitative image quality, CT attenuations of intra-articular contrast mixture and tissues, background noise, contrast-to-noise ratios (CNRs), and figures of merit were assessed. Radiation doses were compared.
CT arthrographies with Sn 100 kV and Sn 140 kV yielded approximately 70% and 60% radiation dose reduction, respectively, compared with the conventional 120 kV (
 < 0.001). MDL-28170 Qualitative image noise and quantitative background noise of Sn 100 kV and Sn 140 kV were significantly less than those of the conventional protocol. Qualitative image contrast, CT attenuations of intra-articular contrast mixture and tissues, and CNRs for Sn 100 were similar to those of the conventional 120 kV. However, Sn 140 kV showed significantly lower qualitative contrast and CNRs than 120 kV. Sn 100 kV was the most dose efficient among the three protocols.
Shoulder CT arthrography with Sn 100 kV substantially reduced radiation dose and image noise and maintained image contrast, compared with the conventional protocol.

Values are understood to be developed during childhood and adolescence but there has been limited exploration of how young people experience values and their function across contexts. This study aimed to explore adolescents' understanding of the concept of 'values' and to elicit their experiences of values. Semi-structured, individual interviews were conducted with 11 adolescents aged 12-17 years. Thematic analysis was used to identify themes. Young people were readily able to discuss the meaning of 'values' and their own personal values. Three main themes were identified (1) what values are (in general, and specific to themselves), (2) where values come from (relationships, education, growing up), and (3) why values are important (prioritising/decision making, reflecting on values is helpful). The adolescents in this study demonstrated an in-depth understanding of the meaning, origins and functions of values. The results suggest young people may welcome and benefit from opportunities to discuss their values, including in therapy.
Deep inferior epigastric perforator (DIEP) flap reconstruction is the gold standard reconstructive technique for women undergoing breast cancer surgery. A preoperative computed tomography angiography (CTA)-dedicated protocol and 3D reconstructions are mandatory for correct surgical planning.
To evaluate the diagnostic performance of a new preoperative CTA protocol and a new reconstruction method in the assessment of DIEP technique.
A total of 263 women (median age 49 years, age range 26-73 years) underwent preoperative CTA examination before DIEP flap breast reconstruction. A CTA-dedicated protocol followed by 3D-reconstructions were performed. Identification, branching pattern, and caliber at origin were assessed for each perforator. Intraoperative findings were the standard of reference. The sensitivity, positive predictive value, and diagnostic accuracy of the preoperative CTA protocol were calculated.
In 255/263 (97%) patients, the dominant perforators assessed by CTA resulted adequate for surgical reconstruction. In 260/263 (99%) cases, the imaging localization of the dominant perforators corresponded with those seen intraoperatively (mean errors ≤1 cm). The preoperative CTA imaging sensitivity, positive predictive value, and diagnostic accuracy in determining the localization of perforators were 99% (95% CI 98-100), 100% and 99% (95% CI 98-100), respectively. No statistically significant differences were found between the CTA findings and the surgical findings for the assessment of branching pattern and caliber of the dominant perforators (
 < 0.001).
The present protocol has demonstrated high accuracy in the CTA imaging assessment of the perforators before DIEP flap reconstruction with high reproducibility between CT and surgical findings.

Chronic disease poses a major problem for the Australian healthcare system as the leading cost-burden and cause of death. Gastroesophageal reflux disease (GORD) typifies the problems with a growing prevalence and cost. We hypothesise that a scintigraphic test could optimise the diagnosis, especially in problematic extraoesophageal disease.
Data was collected from 2 groups of patients. Patients undergoing fundoplication for severe GORD (n = 30) and those with atypical symptoms (n = 30) were studied by scintigraphy and 24-hour oesophageal pH, impedance and manometry.
Mean age of cohort was 55.8 years with 40 females and 20 males. Body mass index was a mean of 28.3. DeMeester score was normal in 12/60 with atypical symptoms and abnormal in the rest. Good correlation was shown between scintigraphy and impedance, manometry and distal pH readings. Pulmonary aspiration was shown in 25/60 (15 with atypical symptoms) and LPR in 20/30. Several impedance, manometric and scintigraphic finding were good predictors of lung aspiration of refluxate.
Scintigraphy provides a good tool for screening patients with typical and atypical symptoms of GORD. It is well correlated with the standard methods for the diagnosis and provides visual evidence of LPR and lung aspiration.

Our aim is to study the trend of cause of death and risk factors affecting prognosis in the patients. We retrospectively reviewed patients in Surveillance, Epidemiology and End results database from 2004 to 2015. The change trend between cause of death and follow-up time was studied by calculating the proportion of cause of death at different periods and analyzing the cumulative risk. COX risk regression model was performed by univariate and multivariate analyses for survival analysis. Finally, 23,652 patients were enrolled. In the whole cohort, lung cancer accounted for 18.68% of deaths, followed by other causes (9.57%), heart disease (5.12%) and COPD (3.89%). With the increasing of follow-up time, the cumulative incidence of lung cancer was always the highest, but the growth rate in the late follow-up period was slower than that caused by heart disease and COPD. The proportion of death due to lung cancer decreased from 53.1%-73.1% in 0-30 months after follow-up to 7.8%-41.4% in 90 months after follow-up, while the proportion of deaths due to heart disease and COPD increased. Age was an independent risk factor for lung cancer-, heart disease- and COPD-specific survival, while lobectomy resection was a protective factor, even in patients older than 70 years old. In conclusion, during the follow-up period, lung cancer was still the main cause of death, but the proportion of patients died of heart disease and COPD increased gradually, especially in elderly. Furthermore, age was an important independent factor affecting prognosis, particularly for heart disease- and COPD-related mortality. The application of wedge resection in elderly patients needs further exploration.Plant diseases caused by a variety of pathogens can have severe effects on crop plants and even plants in natural ecosystems. Despite many effective conventional approaches to control plant diseases, new, efficacious, environmentally sound and cost-effective approaches are needed, particularly with our increasing human population and the effects on crop production and plant health caused by climate change. RNA interference (RNAi) is a gene regulation and antiviral response mechanism in eukaryotes; transgenic and non transgenic plant-based RNAi approaches have shown great effectiveness and potential to target specific plant pathogens and help control plant diseases, especially when no alternatives are available. Here we discuss ways in which RNAi has been used against different plant pathogens, and some new potential applications for plant disease control.
Cardiac hypertrophy is a key biological response to injurious stresses such as pressure overload and, when excessive, can lead to heart failure. Innate immune activation by danger signals, through intracellular pattern recognition receptors such as nucleotide-binding oligomerization domain 1 (Nod1) and its adaptor receptor-interacting protein 2 (RIP2), might play a major role in cardiac remodeling and progression to heart failure. We hypothesize that Nod1/RIP2 are major contributors to cardiac hypertrophy, but may not be sufficient to fully express the phenotype alone.
To elucidate the contribution of Nod1/RIP2 signaling to cardiac hypertrophy, we randomized Nod1
, RIP2
, or wild-type mice to transverse aortic constriction or sham operations. Cardiac hypertrophy, fibrosis, and cardiac function were examined in these mice.
Nod1 and RIP2 proteins were upregulated in the heart after transverse aortic constriction, and this was paralleled by increased expression of mitochondrial proteins, including mitochVS signaling complex may represent an attractive new therapeutic approach toward heart failure.
To describe the rationale for, and benefits of, trainees and psychiatrists to be involved in medico-political volunteering.
Volunteering for professional organisations and other bodies may be considered as an important advocacy role for psychiatrists. Such volunteering is meaningful through shared goals and achievements, as well as developing a sense of mastery and significance as part of a larger quest. Volunteering is also a professional developmental process that both enhances individual skills/career development as well as organisational efficacy.
