Ciliary muscle morphology in emmetropia and ocular biometric correlates

Purpose: Recent studies have documented a link between axial myopia and ciliary muscle morphology; yet, the variation in biometric characteristics of the emmetropic ciliary muscle are not fully known. Ciliary muscle morphology, including symmetry, was investigated between both eyes of emmetropic participants and correlated to ocular biometric parameters. Methods: Anterior segment optical coherence tomography (Zeiss, Visante) was utilised to image both eyes of 49 emmetropic participants (mean spherical equivalent refractive error (MSE) ≥ -0.55; < +0.75 D), aged 19 to 26 years. High resolution images were obtained of nasal and temporal aspects of the ciliary muscle in the relaxed state. MSE of both eyes was recorded using the Grand Seiko WAM 5500; axial length (AXL), anterior chamber depth (ACD) and lens thickness (LT) of the right eye were obtained using the Haag-streit Lenstar LS 900 biometer. A bespoke semi-objective analysis programme was used to measure a range of ciliary muscle parameters. Results: Temporal ciliary muscle overall length (CML) was greater than nasal CML, in both eyes (right: 3.58 ± 0.40 mm and 3.85 ± 0.39 mm for nasal and temporal aspects, respectively, P < 0.001; left: 3.65 ± 0.35 mm and 3.88 ± 0.41 mm for nasal and temporal aspects, respectively, P < 0.001). Temporal ciliary muscle thickness (CMT) was greater than nasal CMT at 2 mm and 3 mm from the scleral spur (CM2 and CM3, respectively) in each eye (right CM2: 0.29 ± 0.05 mm and 0.32 ± 0.05 mm for nasal and temporal aspects, respectively, P < 0.001; left CM2: 0.30 ± 0.05 mm and 0.32 ± 0.05 mm for nasal and temporal aspects, respectively, P < 0.001; right CM3: 0.13 ± 0.05 mm and 0.16 ± 0.04 mm for nasal and temporal aspects, respectively, P < 0.001; left CM3: 0.14 ± 0.04 mm and 0.17 ± 0.05 mm for nasal and temporal aspects, respectively, P < 0.001). AXL was positively correlated with ciliary muscle anterior length (AL) (e.g. P < 0.001, r2 = 0.262 for left temporal aspect), CML (P = 0.003, r2 = 0.175 for right nasal aspect) and ACD (P = 0.01, r2 = 0.181). Conclusions: Morphological characteristics of the ciliary muscle in emmetropic eyes display high levels of symmetry between the eyes. Greater CML and AL are linked to greater AXL and ACD, indicating ciliary muscle growth with normal ocular development.

Can aberrometry provide rapid and reliable measures of subjective depth of focus following multifocal intraocular lens implantation?

Purpose: To determine whether the ‘through-focus’ aberrations of a multifocal and accommodative intraocular lens (IOL) implanted patient can be used to provide rapid and reliable measures of their subjective range of clear vision. Methods: Eyes that had been implanted with a concentric (n = 8), segmented (n = 10) or accommodating (n = 6) intraocular lenses (mean age 62.9 ± 8.9 years; range 46-79 years) for over a year underwent simultaneous monocular subjective (electronic logMAR test chart at 4m with letters randomised between presentations) and objective (Aston open-field aberrometer) defocus curve testing for levels of defocus between +1.50 to -5.00DS in -0.50DS steps, in a randomised order. Pupil size and ocular aberration (a combination of the patient’s and the defocus inducing lens aberrations) at each level of blur was measured by the aberrometer. Visual acuity was measured subjectively at each level of defocus to determine the traditional defocus curve. Objective acuity was predicted using image quality metrics. Results: The range of clear focus differed between the three IOL types (F=15.506, P=0.001) as well as between subjective and objective defocus curves (F=6.685, p=0.049). There was no statistically significant difference between subjective and objective defocus curves in the segmented or concentric ring MIOL group (P>0.05). However a difference was found between the two measures and the accommodating IOL group (P<0.001). Mean Delta logMAR (predicted minus measured logMAR) across all target vergences was -0.06 ± 0.19 logMAR. Predicted logMAR defocus curves for the multifocal IOLs did not show a near vision addition peak, unlike the subjective measurement of visual acuity. However, there was a strong positive correlation between measured and predicted logMAR for all three IOLs (Pearson’s correlation: P<0.001). Conclusions: Current subjective procedures are lengthy and do not enable important additional measures such as defocus curves under differently luminance or contrast levels to be assessed, which may limit our understanding of MIOL performance in real-world conditions. In general objective aberrometry measures correlated well with the subjective assessment indicating the relative robustness of this technique in evaluating post-operative success with segmented and concentric ring MIOL.

Clinical characteristics and benefit of cataract intervention amongst UK domiciliary eye care recipients

Purpose: Given the ageing UK population and the high prevalence of activity-limiting illness and disability in the over 65s, the demand for domiciliary eye care services is set to grow significantly. Over 400,000 NHS domiciliary eye examinations are conducted each year, yet minimal research attention has been directed to this mode of practice or patient needs amongst this group. The study aimed to compare clinical characteristics and benefits of cataract surgery between conventional in-practice patients and domiciliary service users. Methods: Clinical characteristics were compared between patients in North-West England receiving NHS domiciliary eye care services (n = 197; median age 76.5 years), and an age-matched group of conventional in-practice patients (n = 107; median age 74.6 years). Data including reason for visit; logMAR uncorrected and best corrected distance (UDVA and CDVA) and near acuities (UNVA and CNVA); presence of ocular pathology and examination outcome were documented retrospectively. To compare the benefit of cataract surgery in terms of functional capacity between the patient groups, individuals undergoing routine referral for first-eye surgery completed the VF-14 questionnaire pre-operatively, and at 6 weeks post-operatively. Results: UDVA was similar between the two groups (median 0.48 and 0.50 logMAR in the domiciliary and practice groups, P = 0.916); CDVA was significantly worse in the domiciliary group (median 0.18 vs 0.08 logMAR, P<0.001), who were more likely to have clinically-significant cataract. Both groups showed similar improvements in VF-14 scores following cataract surgery (mean gains 24.4 ± 11.7, and 31.5 ± 14.7 points in the in-practice and domiciliary groups, respectively. P = 0.312). Conclusions: Patients receiving domiciliary eye care services are more likely to have poorer corrected vision than in-practice patients of a similar age, partly due to a higher prevalence of significant cataract. Despite limitations in their activities due to illness and disability, domiciliary patients experience similar gains in self-reported functional capacity following cataract surgery

Lessons from the 2015 earthquake(s) in Nepal: implication for rehabilitation.

PURPOSE: There has been an increase in the number of natural disasters in recent history, and the rate of disability is increasing among survivors. The most recent major natural disaster was the earthquake(s) that occurred in Nepal on 25 April 2015 and 12 May 2015. In total, more than 8500 people were killed and over 18,500 people were left injured. This article aims to demonstrate the role of rehabilitation professionals in post-disaster relief and beyond in Nepal. METHOD: This is an experiential account of physiotherapists present during the earthquake and participating in the post-disaster relief. RESULTS: Rehabilitation professionals played an important role in the acute phase post-disaster by providing essential services and equipment. However, discharge planning emerged as an important role for rehabilitation providers in the early days of post-disaster and signaled a relatively new and innovative function that facilitated the heavy imbalance between little supply and tremendous demand for care. In the coming years, rehabilitation will need to support local initiatives that focus on minimizing the long-term effects among people with a newly acquired disability. CONCLUSIONS: Rehabilitation serves an important role across the continuum in post-disaster relief from the initial stages to the months and years following an event. IMPLICATIONS FOR REHABILITATION: Driven by medical advances in acute field medicine, the relative proportion of casualties following natural disasters is decreasing, while relative rates of disability are rising among survivors. In post-disaster settings, the growing number of people with newly acquired disabilities will be added to the existing proportion of the population who lived with disabilities, creating a significant growth in the total number of people with disabilities (PWDs) in communities that are often ill prepared to provide necessary services. Rehabilitation interventions in the initial stages of emergency humanitarian response can minimize the long-term effects among people with newly acquired disabilities through early activation and prevention of secondary effects. Rehabilitation providers thus appear to have an important mediating effect on outcomes of disabilities in the early stages, but must also be strong partners with PWDs to advocate for social and political change in the long term.

Combined analysis of variation in core, accessory and regulatory genome regions provides a super-resolution view into the evolution of bacterial populations

The use of whole-genome phylogenetic analysis has revolutionized our understanding of the evolution and spread of many important bacterial pathogens due to the high resolution view it provides. However, the majority of such analyses do not consider the potential role of accessory genes when inferring evolutionary trajectories. Moreover, the recently discovered importance of the switching of gene regulatory elements suggests that an exhaustive analysis, combining information from core and accessory genes with regulatory elements could provide unparalleled detail of the evolution of a bacterial population. Here we demonstrate this principle by applying it to a worldwide multi-host sample of the important pathogenic E. coli lineage ST131. Our approach reveals the existence of multiple circulating subtypes of the major drug–resistant clade of ST131 and provides the first ever population level evidence of core genome substitutions in gene regulatory regions associated with the acquisition and maintenance of different accessory genome elements.

Table 1. Tree growth index and reconstructed precipitation series from 515 BC to AD 1993 based on the archaeological and living tree ring datasets from Dulan and Shenge, China

Annual precipitation for the last 2,500 years was reconstructed for northeastern Qinghai from living and archaeological juniper trees. A dominant feature of the precipitation of this area is a high degree of variability in mean rainfall at annual, decadal, and centennial scales, with many wet and dry periods that are corroborated by other paleoclimatic indicators. Reconstructed values of annual precipitation vary mostly from 100 to 300 mm and thus are no different from the modern instrumental record in Dulan. However, relatively dry years with below-average precipitation occurred more frequently in the past than in the present. Periods of relatively dry years occurred during 74-25 BC, AD 51-375, 426-500, 526-575, 626-700, 1100-1225, 1251-1325, 1451-1525, 1651-1750 and 1801-1825. Periods with a relatively wet climate occurred during AD 376-425, 576-625, 951-1050, 1351-1375, 1551-1600 and the present. This variability is probably related to latitudinal positions of winter frontal storms. Another key feature of precipitation in this area is an apparently direct relationship between interannual variability in rainfall with temperature, whereby increased warming in the future might lead to increased flooding and droughts. Such increased climatic variability might then impact human societies of the area, much as the climate has done for the past 2,500 years.

Discourse on equality in organizations. A case study of the chemical industry in Tarragona

This paper presents a proposal for analyzing discourses on gender equality in organizations. The research is carried out as a case study, focusing on the chemical industry in Tarragona. To the question: why there are still so many differences between women and men in labour market, despite having multiple tools to avoid inequalities? we propose to focus on discourses of equality to find an answer. The viewpoint that companies have on gender is crucial in enabling policies for equality. To ensure that policies are truly aimed at promoting equality, it is needed a gender approach that nowadays is not widespread in organizations. From these considerations, we present a fourfold typology of discourses on equality in organizations.

Cooperative or collaborative learning: Is there a difference in university students’ perceptions?

The hypothesis that the same educational objective, raised as cooperative or collaborative learning in university teaching does not affect students’ perceptions of the learning model, leads this study. It analyses the reflections of two students groups of engineering that shared the same educational goals implemented through two different methodological active learning strategies: Simulation as cooperative learning strategy and Problem-based Learning as a collaborative one. The different number of participants per group (eighty-five and sixty-five, respectively) as well as the use of two active learning strategies, either collaborative or cooperative, did not show differences in the results from a qualitative perspective.

What is this thing called Historical Archaeology?

Historical archaeology, in its narrow temporal sense -as an archaeology of the emergence and subsequent evolution of the Modern world- is steadily taking pace in Spanish academia. This paper aims at provoking a more robust debate through understanding how Spanish historical archaeology is placed in the international scene and some of its more relevant particularities. In so doing, the paper also stresses the strong links that have united historical and prehistorical archaeology since its inception, both in relation to the ontological, epistemological and methodological definition of the first as to the influence of socio-political issues in the latter. Such reflection is partly a situated reflection from prehistory as one of the paper’s authors has been a prehistorian for most of her professional life.

Climate change-related regime shifts have altered spatial synchrony of plankton dynamics in the North Sea

During the 1980s, the North Sea plankton community underwent a well-documented ecosystem regime shift, including both spatial changes (northward species range shifts) and temporal changes (increases in the total abundances of warmer water species). This regime shift has been attributed to climate change. Plankton provide a link between climate and higher trophic-level organisms, which can forage on large spatial and temporal scales. It is therefore important to understand not only whether climate change affects purely spatial or temporal aspects of plankton dynamics, but also whether it affects spatiotemporal aspects such as metapopulation synchrony. If plankton synchrony is altered, higher trophic-level feeding patterns may be modified. A second motivation for investigating changes in synchrony is that the possibility of such alterations has been examined for few organisms, in spite of the fact that synchrony is ubiquitous and of major importance in ecology. This study uses correlation coefficients and spectral analysis to investigate whether synchrony changed between the periods 1959–1980 and 1989–2010. Twenty-three plankton taxa, sea surface temperature (SST), and wind speed were examined. Results revealed that synchrony in SST and plankton was altered. Changes were idiosyncratic, and were not explained by changes in abundance. Changes in the synchrony of Calanus helgolandicus and Para-pseudocalanus spp appeared to be driven by changes in SST synchrony. This study is one of few to document alterations of synchrony and climate-change impacts on synchrony. We discuss why climate-change impacts on synchrony may well be more common and consequential than previously recognized.
