Workforce survey of Australian graduate health information managers: Employability, employment, and knowledge and skills used in the workplace

Background: Employability, employment destinations and utilisation of knowledge–skill domains of new graduate health information managers (HIMs) have not been explored. Objectives: To capture the timing from course completion to employment and employment locations of a 5-year cohort of health information management graduates of La Trobe University, Australia, in 2017–2018; identify professional knowledge and skills used by the graduates in executing their roles; and map these to four domains of the health information management curriculum. Method: A mixed-methods descriptive study utilising a survey investigated early career pathways of new graduates of health information management courses from 2012 to 2016. Demographic data included age, year of graduation, lead time from course completion to employment, position title, number of positions held post-graduation and knowledge–skills used in the workplace. Results: Eighty percent (n = 167) of graduates working in Australia with known contact details responded to the survey. Of these, 96.4% (n = 161) worked in at least one “health information management-related” position since graduation. Forty-five percent (n = 72) of graduates obtained a position before course completion, and over 94% (n = 150) were employed in the profession within 6 months of completion. Sixty percent (n = 97) of graduates had worked in two or more positions from 2012 to 2016. The large majority of new graduate HIMs (82.4%) were employed in the public healthcare sector in “health information management” (44%), or “health classification” (28.1%) roles. Most graduates (61%) had utilised at least three or four domains of professional knowledge–skills in the workplace. Whereas 16% (n = 26) of graduates used, solely, their health classification knowledge–skill set, almost 74% (n = 117) undertook some health classification-related activities. Only 16% (n = 26) of graduates were over 40 years of age, and there were no statistically significant differences between Bachelor and Master (Combined Degree Programs) graduates and Graduate-entry Master degree graduates in terms of lead time to employment, number of positions held, type of employing agency and professional knowledge–skills utilised in the workplace. Conclusion: Graduate HIMs have very high employability, demonstrate job mobility consistent with the national trends, are largely represented in the public sector but have presence throughout the healthcare system and utilise most or all of the specialised domains of professional knowledge and skills studied at university.
On the kurtosis of ocean waves in deep water

In this paper, we revisit Janssen’s (2003) formulation for the dynamic excess kurtosis of weakly nonlinear gravity waves in deep water. For narrowband directional spectra, the formulation is expressed as a sixfold integral that depends upon the Benjamin-Feir index and the parameter R = ν/2σ θ , a measure of short-crestedness for the dominant waves with ν and σθ denoting spectral bandwidth and angular spreading. Thus, Janssen’s formulation leads to an analytical solution for the dynamic kurtosis of narrowband directional waves described with a Gaussian type spectrum. For short-crested seas (R > 0) in a focusing (defocusing) regime, dynamic kurtosis grows initially, attaining a positive maximum (negative minimum) at the intrinsic time scale
Recent advances in the development of polyethylenimine-based gene vectors for safe and efficient gene delivery

ABSTRACT Introduction Despite the great therapeutic potential of gene therapy for treating critical diseases, the clinical application is limited by lack of safe and effective gene delivery vectors. Nonviral gene vectors have attracted tremendous attention due to the favorable loading capacity and facile manufacture. Among them, polyethylenimine-based gene vectors (PEIs) hold great promise for highly efficient gene delivery. Areas covered In this review, we outline the multiple biological barriers associated with gene delivery process and point out several challenges exist in the clinical usage of PEIs. We then provide an overview of the most impressive progresses made to overcome such challenges in recent years, including modifications of PEIs (i.e. to enhance biocompatibility, specific targeting effect, and buffering capacity) and stimuli-responsive strategies (i.e. endogenous and exogenous stimuli) for safe and efficient gene delivery. Expert opinion Rational modification of PEIs with diverse functionalized segments or the development of stimuli-responsive PEIs is an appealing strategy to meet some requirements involved in gene delivery. Nevertheless, further optimization by combining the two strategies is needed for the maximized transfection efficiency and minimized side effects, shedding new light on the development of nonviral gene delivery for clinical application.
Evaluation of rodent control to fight Lassa fever based on field data and mathematical modelling

ABSTRACT The Natal multimammate mouse (Mastomys natalensis) is the reservoir host of Lassa virus, an arenavirus that causes Lassa haemorrhagic fever in humans in West Africa. Because no vaccine exists and therapeutic options are limited, preventing infection through rodent control and human behavioural measures is currently considered to be the only option. In order to assess the efficacy of rodent control, we performed a 4-year field experiment in rural Upper Guinea and developed a mathematical model to simulate different control strategies (annual density control, continuous density control, and rodent vaccination). For the field study, rodenticide baits were placed each year in three rural villages, while three other villages were used as controls. Rodents were trapped before and after every treatment and their antibody status and age were determined. Data from the field study were used to parameterize the mathematical model. In the field study, we found a significant negative effect of rodent control on seroprevalence, but this effect was small especially given the effort. Furthermore, the rodent populations recovered rapidly after rodenticide application, leading us to conclude that an annual control strategy is unlikely to significantly reduce Lassa virus spillover to humans. In agreement with this finding, the mathematical model suggests that the use of continuous control or rodent vaccination is the only strategy that could lead to Lassa virus elimination. These field and model results can serve as a guide for determining how long and frequent rodent control should be done in order to eliminate Lassa virus in rural villages.
Noninvasive diagnosis of urothelial cancer in urine using DNA hypermethylation signatures—Gender matters

Urothelial cancer (UCa) is the most predominant cancer of the urinary tract and noninvasive diagnosis using hypermethylation signatures in urinary cells is promising. Here, we assess gender differences in a newly identified set of methylation biomarkers. UCa‐associated hypermethylated sites were identified in urine of a male screening cohort (n = 24) applying Infinium‐450K‐methylation arrays and verified in two separate mixed‐gender study groups (n = 617 in total) using mass spectrometry as an independent technique. Additionally, tissue samples (n = 56) of mixed‐gender UCa and urological controls (UCt) were analyzed. The hypermethylation signature of UCa in urine was specific and sensitive across all stages and grades of UCa and independent on hematuria. Individual CpG sensitivities reached up to 81.3% at 95% specificity. Albeit similar methylation differences in tissue of both genders, differences were less pronounced in urine from women, most likely due to the frequent presence of squamous epithelial cells and leukocytes. Increased repression of methylation levels was observed at leukocyte counts ≥500/μl urine which was apparent in 30% of female and 7% of male UCa cases, further confirming the significance of the relative amounts of cancerous and noncancerous cells in urine. Our study shows that gender difference is a most relevant issue when evaluating the performance of urinary biomarkers in cancer diagnostics. In case of UCa, the clinical benefits of methylation signatures to male patients may outweigh those in females due to the general composition of women's urine. Accordingly, these markers offer a diagnostic option specifically in males to decrease the number of invasive cystoscopies.
Relative Effect of Current Intensive Lipid-Lowering Drugs on Cardiovascular Outcomes in Secondary Prevention　- A Meta-Analysis of 12 Randomized Trials.

BACKGROUND We aimed to investigate the comparative cardiovascular benefits of high-dose statin, ezetimibe-statin, and PCSK9 inhibitor-statin treatments in secondary prevention patients.Methods and Results:We selected 12 randomized controlled trials (n=131,978 patients) using PubMed and Embase (inception-June 1, 2018). Subgroup differences were explored by meta-regression and Cochran Q test. The relative effects of high-dose statin, ezetimibe-statin, and PCSK9 inhibitor-statin on major cardiovascular events (MACE), and revascularization were varied and decreased gradually, of which high-dose statin resulted in lower risk of MACE and revascularization than PCSK9 inhibitor-statin per 1 mmol/L reduction of low-density lipoprotein cholesterol (LDL-C): risk ratio (RR) for MACE, 0.86 (95% confidence interval (CI), 0.81-0.90) for high-dose statin, 0.90 (95% CI, 0.83-0.96) for ezetimibe-statin, and 0.94 (95% CI, 0.92-0.96) for PCSK9 inhibitor-statin; RR for revascularization, 0.84 (95% CI, 0.77-0.90) for high-dose statin, 0.91 (95% CI, 0.81-1.00) for ezetimibe-statin, and 0.94 (95% CI, 0.90-0.97) for PCSK9 inhibitor-statin. Similar relative effects of intensive lipid-lowering treatment were also observed in analyses of myocardial infarction and stroke, although no significant difference between groups was identified. CONCLUSIONS In secondary prevention patients, the relative benefits of high-dose statin, ezetimibe-statin, and PCSK9 inhibitor-statin treatments were varied and decreased gradually, of which high-dose statin was significantly superior to PCSK9 inhibitor-statin for improving MACE and revascularization per 1 mmol/L reduction of LDL-C.
Health Regulatory Focus, Selection Optimization and Compensation Strategy and Sports Practice: A Mediational Analysis

Abstract This study aimed to investigate associations of health promotion and prevention regulatory foci with sports practice, and examined the Selection, Optimization and Compensation (SOC) process behind the positive relationship between health promotion focus and sports practice. A cross-sectional study was conducted with 513 French volunteer sports participants aged from 18 to 82. Participants completed an online self-report survey measuring health regulatory foci, SOC strategy, Amount of Sports Practice (ASP), health condition, and educational level. Path analysis main results (χ2 = 16.64; df = 5; p < .01; RMSEA = 0.067; CFI = 0.98; R2 = .24) demonstrated that ASP was positively related with health promotion focus (β = .13, p < .01), SOC strategy (β = .28, p < .001) and negatively related with health prevention focus (β = –.20, p < .001). SOC strategy was positively related with health promotion focus (β = .39, p < .001) and bootstrapping analyses revealed that this strategy partially mediated the positive relationship between health promotion focus and ASP, 95% CI [. 13, . 29]. Finally, additional analyses showed that it was specifically the elective selection, optimization and compensation sub-components of SOC strategy which played mediating roles in this link, [. 13, . 29] < 95% CI < [. 13, . 29]. For the first time in the literature, these results evidenced direct links between health regulatory foci and sports practice, and a mechanistic pathway between health promotion focus and sports practice. The theoretical and applied implications of these results for sports promotion are discussed.
Adrenocortical and autonomic attunement between romantic partners in emerging adulthood

Abstract Parent-child physiological attunement, particularly during stressful situations, appears adaptive as shared stress reactivity may promote dyadic engagement. Romantic partners eventually replace parents as the primary support figure, yet it remains unclear whether romantic partners buffer physiological stress or display physiological attunement as most studies on adults examine attunement during conflict paradigms. The present study examined physiological attunement in 63 emerging adult romantic partner dyads (one partner was the active participant, the other the observer) during the Trier Social Stress Task (TSST). Heart rate (HR) and respiratory sinus arrhythmia (RSA) were continuously monitored across the visit. Repeated saliva samples were assayed for cortisol. Physiological attunement was operationalized as a correlation in biomarkers between the TSST participant and their partner; sex, social support, and physical proximity were examined as moderators. We then compared the biomarker profiles of partnered-TSST participants to individuals who participated in the TSST solo (n = 63) to determine if partner presence buffered stress biomarker reactivity during the TSST. RSA attunement between partners was found but was not further moderated by social support or sex. Adrenocortical attunement was moderated, such that lower social support and increased proximity resulted in higher attunement. HR attunement was higher when the participant was male and when partners were in close physical proximity. Compared to TSST solo, romantic partner presence increased participant cortisol levels and altered HR reactivity, suggesting that emerging adult romantic partners do not buffer physiological stress reactivity. Future research should examine whether physiological attunement and partner presence is protective in more established relationships.
Do two venous anastomoses decrease venous thrombosis during limb reconstruction?

BACKGROUND The optimal number of veins to be anastomosed in perforator flaps for limb reconstruction and its influence on the results remain controversial. Venous thrombosis of microvascular anastomoses is a commonly recorded complication in soft tissue reconstruction. OBJECTIVE To evaluate the effect of two venous anastomoses in the incidence of venous thrombosis for limb reconstruction using anterolateral thigh (ALT) microsurgical free flaps. METHODS This was a cross-sectional study on patients undergoing limb reconstruction using ALT flap during 2014-2017. Perioperative information was recorded and patients were divided in two groups: group 1 (one venous anastomosis; 17 patients) and group 2 (two venous anastomoses; 21 patients). Complications were investigated. RESULTS Overall, 38 microsurgical flaps were included. The mean age was 33 years, and 32 patients were male. The most prevalent wounds were traumatic. Group 1 presented a higher complication rate than group 2 (47% vs. 24%; p = 0.065), although the difference was not significant. Group 1 presented a higher rate of venous anastomotic thrombosis (p = 0.032) than group 2. The overall success rate was 92%. CONCLUSION For limb reconstruction using ALT microsurgical free flaps, two venous anastomoses are associated with a low rate of venous thrombosis in microvascular anastomoses.
Breast Augmentation

Learning Objectives: After studying this article, the participant should be able to: 1. Assess patient physical characteristics that influence implant selection. 2. Adopt a system to aid in implant size selection. 3. Become cognizant of the advantages and disadvantages of incision, pocket plane, and implant options. 4. Understand implant positioning concepts and aseptic implant handling methods. 5. Manage untoward postoperative sequelae 6. Understand secondary surgery concepts. Summary: Breast augmentation is the most commonly performed aesthetic surgical procedure. Choices of incisions, pocket plane, and myriad implant characteristics constitute the basis for surgical planning. Analysis of physical characteristics and inclusion of the patient in implant selection contribute to overall satisfaction and reduce requests for secondary surgery. Technical expertise in implant positioning and aseptic handling helps to prevent capsular contracture, implant malposition, and other shape problems. Despite the need for secondary surgery in some, patient satisfaction is high.

MFSD8 gene mutations; evidence for phenotypic heterogeneity

ABSTRACT Background: Cone–rod dystrophies are a group of genetically and phenotypically heterogeneous inherited degenerative retinal diseases primarily affecting macular and cone system function. MFSD8 loss-of-function variants are mainly related to the variant late-infantile neuronal ceroid lipofuscinoses which present with progressive motor and mental regression in combination with seizures, ataxia, and visual impairment. Material and methods: Clinical examination and genomic DNA extraction were collected from two unrelated Iranian families presenting with autosomal recessive cone–rod dystrophy. The candidate disease-causing variant was screened with whole-exome sequencing and bioinformatics analyses. Sanger sequencing was used for validation and co-segregation analysis. Results: Two previously reported variants (c.1361T>C; p.M454T and c.1235C>T; p.P412L) and in a compound heterozygous pattern in one family and a homozygous variant (c.1361T>C; p.M454T) identical to one of the variants in the first family in MFSD8 gene were identified. Both confirmed by Sanger sequencing and co-segregated with disease status. Conclusions: Here and for the first time, we reported on two previously variant late-infantile neuronal ceroid lipofuscinoses-associated variants in MFSD8 but in association with a form of cone–rod dystrophy known as non-syndromic macular dystrophy with central cone involvement. Our results support this concept that variant late-infantile neuronal ceroid lipofuscinoses and non-syndromic macular dystrophy with central cone involvement are not different disease entities, but rather allelic diseases and phenotypic variants of the same mutation. Consideration of the milder MFSD8 phenotypes is important against the potentially severe consequences of life-threatening conditions associated with MFSD8 mutations in order to prevent the danger of misdiagnosis as well as the accuracy of genetic counseling.
Gasdermin D: in vivo evidence of pyroptosis in spontaneous labor at term

Abstract Objective: Pyroptosis is an inflammatory form of programmed cell death that is mediated by the activation of the inflammasome and depends on the pore-forming function of gasdermin D. Therefore, the detection of gasdermin D represents in vivo evidence of pyroptosis. We recently showed that there is intra-amniotic inflammasome activation in spontaneous labor at term; however, evidence of pyroptosis is lacking. The objectives of this study were to investigate (1) whether gasdermin D is detectable in the amniotic fluid of women who delivered at term; (2) whether amniotic fluid gasdermin D concentrations are associated with the process of spontaneous labor at term; and (3) whether gasdermin D is expressed in the chorioamniotic membranes from these patients. Methods: This retrospective cross-sectional study included amniotic fluid samples from 41 women who underwent spontaneous labor at term (n = 17) or delivered at term without labor (n = 24). As a readout of pyroptosis, gasdermin D was determined in amniotic fluid samples using a specific and sensitive ELISA kit. The 90th percentile of amniotic fluid gasdermin D concentrations was calculated among women without spontaneous labor at term (reference group). The association between high amniotic fluid gasdermin D concentrations (≥90th percentile in the reference group) and spontaneous labor at term was tested using the Fisher’s exact test. A p value <. 05 was considered significant. Multiplex immunofluorescence staining and phenoptics (multispectral imaging) were performed to determine gasdermin D expression in the chorioamniotic membranes and to colocalize this protein with the inflammasome-related molecules caspase-1 and interleukin-1β. Results: (1) Gasdermin D is present in the amniotic fluid of women who delivered at term; (2) the 90th percentile of amniotic fluid gasdermin D concentrations in women who delivered at term without spontaneous labor was 3.4 ng/mL; (3) the proportion of women with amniotic fluid gasdermin D concentrations above the threshold was higher in those who underwent term labor than in those who delivered at term without labor; (4) amniotic fluid concentrations of gasdermin D > 3.4 ng/mL were significantly associated with the presence of spontaneous labor in women who delivered at term (odds ratio 6.0, p-value .048); and (5) the protein expression of gasdermin D is increased in the chorioamniotic membranes of women who underwent spontaneous labor at term and is colocalized with caspase-1 and IL-1β. Conclusions: Gasdermin D is increased in the amniotic fluid and chorioamniotic membranes of women who underwent spontaneous labor at term compared to those without labor. These data provide evidence implicating pyroptosis in the mechanisms that lead to the sterile inflammatory process of term parturition.
The complex relationship between olivine abundance and thermal inertia on Mars

We examine four olivine‐bearing regions at a variety of spatial scales with thermal infrared, visible to near‐infrared, and visible imagery data to investigate the hypothesis that the relationship between olivine abundance and thermal inertia (i.e., effective particle size) can be used to infer the occurrence of olivine chemical alteration during sediment production on Mars. As in previous work, Nili Fossae and Isidis Planitia show a positive correlation between thermal inertia and olivine abundance in Thermal Emission Spectrometer (TES) and Thermal Emission Imaging System (THEMIS) data, which could be interpreted as indicating olivine chemical weathering. However, geomorphological analysis reveals that relatively olivine‐poor sediments are not derived from adjacent olivine‐rich materials, and therefore, chemical weathering cannot be inferred based on the olivine‐thermal inertia relationship alone. We identify two areas (Terra Cimmeria and Argyre Planitia) with significant olivine abundance and thermal inertias consistent with sand, but no adjacent rocky (parent) units having even greater olivine abundances. More broadly, global analysis with TES reveals that the most typical olivine abundance on Mars is ~5–7% and that olivine‐bearing (5–25%) materials have a wide range of thermal inertias, commonly 25–600 J m−2 K−1 s−1/2. TES also indicates that the majority of olivine‐rich (>25%) materials have apparent thermal inertias less than 400 J m−2 K−1 s−1/2. In summary, we find that the relationship between thermal inertia and olivine abundance alone cannot be used in infer olivine weathering in the examined areas, that olivine‐bearing materials have a large range of thermal intertias, and therefore that a complex relationship between olivine abundance and thermal inertia exists on Mars.
