Abstract
Atopic dermatitis (AD) is a chronic, inflammatory skin condition with a huge disease burden. Attention-deficit/hyperactivity disorder (ADHD) is often diagnosed in children, and is associated with symptoms of inattention, hyperactivity and impulsive behaviour. Observational studies have demonstrated associations between AD and ADHD. However, to date, there has been no formal assessment of causal relationship between the two. We aim to evaluate causal relationships between genetically increased risk of AD and ADHD using Mendelian randomization (MR) approach. Two-sample bi-directional MR was conducted to elucidate potential causal relationships between genetically increased risk of AD and ADHD, using the largest and most recent genome-wide association study datasets for AD and ADHD-EArly Genetics & Lifecourse Epidemiology AD consortium (21 399 cases and 95 464 controls) and Psychiatric Genomics Consortium (20 183 cases and 35 191 controls). Genetically determined increased risk of AD is not associated with ADHD based on genetic information: odds ratio (OR) of 1.02 (95% CI -0.93 to 1.11; p = 0.705). Similarly, genetic determined increased risk of ADHD is not associated with an increased risk of AD: OR of 0.90 (95% CI -0.76 to 1.07; p = 0.236). Horizontal pleiotropy was not observed from the MR-Egger intercept test (p = 0.328) Current MR analysis showed no causal relationship between genetically increased risk of AD and ADHD in either direction in individuals of European descent. Any observed associations between AD and ADHD in previous population studies could possibly be due to confounding lifestyle factors such as psychosocial stress and sleeping habits.

Abstract
By treating a regeneratively mode-locked laser with a short ring length of 5.85 m as a coupled optoelectronic (OE) RF oscillator, the microwave quality factor (Q R F ) of its ring-cavity was characterized with the phase-shift approach. Specifically, the phase shift in the OE feedback loop of the mode-locked laser was varied, and the corresponding frequency shift in the photodetected first harmonic of its emitted pulse train was measured. An optical-gain enhanced Q R F of ∼5.8×104 was measured, which is an order of magnitude larger than the Q R F estimated for the same cavity before regenerative mode-locking. The experimental results were then compared with theoretical models developed to estimate the optical-gain enhanced Q R F of coupled OE oscillators.

Abstract
BACKGROUND Insertion of external ventricular drain (EVD) is one of the most common neurosurgical procedures performed worldwide. This is generally performed freehand, on the basis of anatomical landmarks. There is significant variability in the reported accuracy of freehand placement, lacking Level I evidence. We present the first meta-analysis of freehand EVD placement accuracy and technologies or techniques to enhance accuracy. METHODS We report a systematic review of the Pubmed, Embase, and Cochrane Central databases according to MOOSE (Meta-analysis Of Observational Studies) guidelines. 37 studies were included for qualitative analysis and 19 studies (2983 cases) for quantitative analysis. RESULTS There is substantial heterogeneity in the outcome measures used to report EVD placement accuracy. Of those nineteen studies reporting accuracy using the Kakarla grading system the mean rate of ideal ipsilateral frontal horn placement was 73% (standard deviation ±7%). The use of formal stereotaxic guidance is consistently reported to improve accuracy to >90%, although with variable outcome measures. However, the reported efficacy of other guidance devices or techniques is highly variable. The quality of studies directly comparing all existing non-stereotaxic devices with freehand EVD placement is poor and precludes any assertion of superiority to freehand insertion. CONCLUSIONS We provide the first meta analysis of freehand placement accuracy. There is insufficient data to perform a meta-analysis of the relative efficacy of interventions to improve accuracy. Qualitative synthesis of reports of stereotaxic guidance is suggestive of higher accuracy than freehand placement.

Abstract
We demonstrated a 20.97 GHz regeneratively mode-locked Er fiber laser that has a short ring length of 5.84 m. The short active ring enabled large filter-rejection of adjacent supermodes during extraction of its clock signal for regenerative feedback. Very stable mode locking was observed with the generation of ∼5.5ps Gaussian pulses. A characterization of the noise pedestals in the photodetected first and second harmonics of the mode-locked pulses indicated there was cross-correlated coupling between the timing and amplitude jitter. From an analysis of the noise pedestals in these harmonics, as well as the noise spectrum at baseband, we estimated an amplitude jitter of ∼0.19%, and a timing jitter of ∼60fs. Using a generalized harmonic analysis approach, we estimated a cross correlation of 0.11% between the timing and amplitude jitter.

Abstract
This article discusses risk management processes in Britain’s civil nuclear industry from a corporate governance perspective. As an example of a hazardous industry that can inflict catastrophic environmental damage and fatalities, effective governance of Britain’s nuclear industry is a critical issue. Yet the industry’s history of corporate governance suggests that processes of corporate governance have regularly failed to meet core requirements of its stakeholders. A core requirement is for governance designs that recognize the interests of public owner–stakeholders. In meeting this requirement, the article offers a framework for a relationship-driven form of corporate governance that enables meaningful stakeholder engagement in decision-making.

Abstract
Study background: A retrospective study to compare the rate of facet joint violation (FJV) in lumbar posterior spinal instrumentation using open pedicle screw, percutaneous pedicle screw, and cortical bone trajectory (CBT) technique. CBT is a new posterior spinal instrumentation technique in which a more caudal entry point can minimize iatrogenic damage to the cranial facet joint. Only one recent study reports incidence of FJV of 11%; however, no previous reports comment on radiological outcomes comparing to traditional open and percutaneous screws. Methods: We reviewed 90 patients who underwent lumbar posterior spinal instrumentation from January 2016 to June 2017. Postoperative computer tomography scans were performed to evaluate FJV. Incidence of FJV was graded by three reviewers according to Seo classification. Results: Totally, 446 screws (open 43.4%, percutaneous 37.8%, CBT 18.9%) were inserted. Among these, 6.3% (28/446) had screw head or rod in contact with facet joint and 0.9% (4/446) had screws directly invaded the facet joint. Overall, FJV was 7.2% (CTB = 3.4%, open = 10.4%, and percutaneous = 4.5%, p = 0.075). Conclusion: CBT technique has potential advantage in reducing FJV. It has a unique entry site at lateral aspect of pars interarticular with a caudomedial to craniolateral pathway. It is a reasonable alternative to open or percutaneous techniques in lumbar posterior spinal instrumentation.

Abstract
Abstract
Objective
Repetitive head injuries common in combat sports have been associated with increased risk for cognitive dysfunction. Interestingly, the Professional Fighter’s Brain Health Study (PFBHS) team has observed improvements in fighters’ cognitive performance following their transition to inactive fighting status. As this phenomenon was explored, it was hypothesized that fighters’ cognitive performance will initially improve following their discontinuation of fighting.
Methods
Longitudinal demographic, fighting history, and cognitive functioning data from 31 fighters who discontinued fighting during their participation in the PFBHS. Cognitive functioning was assessed via CNS Vital Signs and C3/iComet computerized batteries. Number of professional fights, as well as inactive fighting status, was determined using published professional online records. Fighters were considered inactive if they had gone two or more years without a professional match.
Results
Paired-samples t test was conducted to evaluate cognitive functioning in fighters at time 1 (actively fighting) and time 2 (inactive fighting status). When comparing cognitive function at across time points, performance on CNS Vital Signs measures of verbal memory, processing speed, psychomotor speed, and reaction time, as well as C3/iComet measures of set-shifting and complex reaction time, significantly improved at time 2 (all p’s < 0.05). Interestingly, performance did not improve across time points on a C3/iComet measure of processing speed (Trailmaking Test Part A).
Conclusions
Cognitive performance improved on most measures when fighters transitioned to inactive fighting status. Given the limited sample size, future analysis is necessary to evaluate the relationship between fighting status and cognitive performance in a larger sample size.

Abstract
Abstract
Objective
Research demonstrates neurodevelopmental diagnoses may increase likelihood of failing scores on ImPACT embedded validity indicators that flag questionable effort. New criteria have been proposed to enhance sensitivity of these indicators although their utility in athletes with neurodevelopmental diagnosis have not been thoroughly examined. This study investigates the effect of neurodevelopmental history on frequency of invalid performance on the standard and three proposed validity indicators.
Methods
Participants included 41,214 high school athletes (Mage = 15.1; 44.2% female; Meducation = 9.1) who completed baseline ImPACT testing. Athletes included these groups: ADHD (3.7%), Learning Disability (LD; 1.5%), Autism (0.2%), ADHD+LD (0.6%), Autism+ADHD/LD (0.1%), athletes with special education history but no diagnosis reported (SpEd; 2.8%), and healthy athletes (91.1%). Odds ratios were calculated to determine differences in invalid performance by both standard and proposed cutoffs.
Results
Neurodevelopmental disorder was associated with increased invalid performance using standard and proposed cutoffs with odds ratios ranging from 1.32 to 3.25. Invalid performance differed significantly across groups for both standard and two sets of proposed criteria (chi square p < .00001). For standard cutoffs, athletes with ADHD, LD, and ADHD/LD were significantly more likely than healthy athletes to have invalid performance. This pattern remained similar across the two sets of proposed criteria.
Conclusions
Results indicate increased incidence of invalid ImPACT performance based on standard and proposed validity indicators in athletes who self-report neurodevelopmental disorders. Findings indicate current and proposed cutoffs may not accurately capture low effort for neurodevelopmental populations. Future research should examine utility of separate cutoff criteria and expanded norms for athletes with neurodevelopmental history.

Abstract
Aim To evaluate the outcome of these complex fractures using a volar approach and the DePuy Synthes variable-angle 2.4-mm distal radius rim plate. This plate is precontoured to the volar rim for placement distal to the watershed line allowing purchase of the rim fragment of the lunate facet. Its low profile and smooth edges are designed to minimize flexor tendon irritation. Method We report on a consecutive series of far distal AO-23B3 and AO-23C3 fractures treated using this plate in a tertiary hand center between November 2011 and May 2014. Range of motion, grip strength, and complications were assessed at the final clinical review. Disabilities of the arm, shoulder, and hand (DASH) and patient evaluation measure (PEM) scores were assessed at 12 months after surgery. Results Twenty-six patients were included in this review. Six patients were lost to follow-up at 3 months. This plate was used in isolation in 17 cases, and in combination with a dorsal plate, in cases of dorsal instability after volar plating, in 10 patients. DASH and PEM scores 1 year after surgery were 17.6 and 27%, respectively. Visual analog scores for patient treatment satisfaction and severity of pain showed good satisfaction with treatment and mild intermittent pain on activity. Postoperative range of motion was variable and grip strength was of 71% of the uninjured contralateral side. There were no cases of flexor or extensor tendon rupture. Tendon irritation was noted in two patients. Removal of metal was performed in four patients. Loss of reduction occurred in one case and neurologic complications in two cases. Conclusion This implant is specifically designed for the management of far distal complex intra-articular fractures of the distal radius. Despite the complexity of these fracture patterns and the challenge they pose to accurate reduction and stable fixation, outcomes were satisfactory in this small series. There were no cases of tendon rupture. Removal of metal is not necessary in all cases, but prompt removal should be performed in cases of tendon irritation in view of the risk of tendon rupture.

Abstract
Abstract
Purpose:Randomized clinical trials describe the benefit of chemo-and immunotherapy for specific breast cancer patients with selected patient and disease characteristics. However, variability in practice occurs despite evidence-based guidelines [1]. The overall survival benefit for the whole population of breast cancer patients in Australia, if evidence-based guidelines for chemo-and immunotherapy were implemented, is unknown. Our study's purpose was to estimate the overall population survival benefit of routinely using evidence-based practice.
Methods and Materials:Decision trees with evidence-based indications for chemotherapy have been previously defined [2]. Each branch corresponds to a specific cohort who have, or do not have, defined indications for chemotherapy and/or immunotherapy. Chemo -and immunotherapy benefit was defined as the absolute incremental benefit of either chemotherapy and/or immunotherapy over no chemo- and/or immunotherapy for radical and palliative indications. Multiple electronic citation databases were systematically queried, including Medline and the Cochrane Library. In cases where there were multiple sources of the same level of evidence, hierarchical meta-analysis was performed. The benefits of chemo- and immunotherapy were estimated for 1, 5, 10-year survival. To assess the robustness of our estimates, sensitivity analyses were performed.
Results: The estimated 1-year, 5-year and 10-year absolute population-based overall survival benefits of optimally utilized chemo- and immunotherapy for breast cancer in Australia are 1.0% (95% CI, 0.9%-1.2%), 4.4% (95% CI, 4.3%-4.6%) and 5.2% (%-%), respectively. They are summarized in the Table 1.

Conclusion: Chemo- and immunotherapy agents improves overall survival in breast cancer at 1-, 5- and 10-years. Chemo-and immunotherapy provides a modest survival benefit to this patient population in Australia when it is used in accordance with guideline recommendations. These outcomes may allow comparison of treatment outcomes in a jurisdiction against what would be considered optimal based on evidence.

Abstract
BACKGROUND Human polo-like kinase 1 (PLK1) expression has been associated with inferior outcomes in colorectal cancer. Our aims were to analyse PLK1 in rectal cancer, and its association with clinicopathological variables, overall survival as well as tumour regression to neoadjuvant treatment. METHODS PLK1 expression was quantified with immunohistochemistry in the centre and periphery (invasive front) of rectal cancers, as well as in the involved regional lymph nodes from 286 patients. Scores were based on staining intensity and percentage of positive cells, multiplied to give weighted scores from 1-12, dichotomised into low (0-5) or high (6-12). RESULTS PLK1 scores in the tumour periphery were significantly different to adjacent normal mucosa. Survival analysis revealed that low PLK1 score in the tumour periphery had a hazard ratio of death of 0.59 in multivariate analysis. Other predictors of survival included age, tumour depth, metastatic status, vascular and perineural invasion and adjuvant chemotherapy. There was no statistically significant correlation between PLK1 score and histological tumour regression in the neoadjuvant cohort. CONCLUSION Low PLK1 score was an independent predictor of superior overall survival, adjusting for multiple clinicopathological variables including treatment.

Abstract
BACKGROUND Recent data show a falling cancer mortality in the general population without a similar shift in immigrant outcomes, leading to a greater cancer burden and mortality for immigrants. Our aims were to compare perceived patterns of care in immigrants and native-born cancer patients. PATIENTS AND METHODS This was a hospital-based sample of first-generation immigrants and Australian-born Anglo patients in the first year following diagnosis. It was restricted to Chinese, Arabic, or Greek speakers. Eligible participants, recruited via 16 oncology clinics, were over 18, with cancer (any type or stage), and having commenced treatment at least 1 month previously. Five hundred and seventy-one CALD patients (comprising 145 Arabic, 248 Chinese, and 178 Greek) and a control group of 274 Anglo-Australian patients participated. RESULTS Immigrants had difficulty communicating with the doctor (73% versus 29%) and understanding the health system (38% versus 10%). Differences were found in 'difficulty knowing who to see' (P = 0.0002), 'length of time to confirm diagnosis' (P = 0.04), wanting more choice about a specialist and hospital (P < 0.0001); being offered the opportunity to see a counselor (P < 0.0001); and actually seeing one (P < 0.0001). There were no significant self-reported differences regarding how cancer was detected, time to see a health professional, or type first seen; however, immigrants reported difficulty knowing who to see. Previous studies showed differences in patterns of care according to socioeconomic status (SES) and educational level. Despite adjusting for age, sex, education, marital status, SES, time since diagnosis, and type of cancer, we did not find significant differences. Instead, we found that understanding of the health system and confidence understanding English were important factors. CONCLUSIONS This study confirmed that immigrants with cancer perceive an inferior quality of cancer care. We highlight potentially modifiable factors including assistance in navigating the health system, translated information, and cultural competency training for health professionals.
