Optical coherence tomography in patients undergoing cataract surgery.

PURPOSE To assess the ability of spectral domain optical coherence tomography (SD-OCT) to diagnose macular changes pre- and post-cataract surgery and to identify changes in central foveal thickness (CFT) relative to age, sex, and presence of concomitant ophthalmic pathologies, for a period of 6 months post-surgery. METHODS A prospective study of patients evaluated by SD-OCT within 5 h before surgery at 7, 30, 60, 90, and 180 days post-op, with respect to CFT and presence of maculopathy. RESULTS Ninety-eight eyes of 98 patients were evaluated, with the following mean results: age = 71.4 years, pre-op VA = 0.27 logMAR, and final VA = 0.73 logMAR. There were 21 eyes in patients with diabetes mellitus (DM) and 10 eyes with age-related macular degeneration (AMD), three with epiretinal membrane, and four with glaucoma. Sixty eyes had no other ophthalmic-related pathologies (NOO), and had a mean pre-op CFT of 222 μm, which progressively increased up to the 60th day post-op, reaching a mean of 227.2 μm. No pseudophakic cystoid macular edema was observed. The mean CFT was statistically significantly different (p<0.001) between NOO and diabetic patients from 30 days post-op. Four eyes presented with preoperative diagnosis of AMD as measured by ophthalmoscopy. After completion of the OCT, which was performed within 5 h before surgery, six additional patients were found to have AMD. Of the 98 total eyes, 10 were diagnosed with maculopathy only by OCT exam. Binocular indirect ophthalmoscopy (BIO) was unable to detect such changes. CONCLUSION OCT diagnosed preoperative maculopathies in 21.4% of the patients, and was more effective than BIO (11.2%). OCT showed a progressive increase in CFT in diabetics up to 180 days post-operatively, as well as greater CFT in male patients and patients older than 70 years.

Attention deficit hyperactivity disorder (ADHD) is one of the most common mental health disorders and it is threatening especially to the academic performance of children. Its neurobiological diagnosis is essential for clinicians to treat ADHD patients properly. Along with machine learning algorithms, and neuroimaging technologies, especially functional magnetic resonance imaging is increasingly used as biomarker in attention deficit hyperactivity disorder. Also, machine learning methods have been becoming popular at last times. This study presents an optimized 3-dimensional convolutional neural network to classify functional magnetic resonance imaging volumes into two classes to assist experts in diagnosing ADHD. To demonstrate the importance of extracting 3D relationships of data, the method has been tested on ADHD-200 public datasets and its performance on the hold-out testing datasets has been evaluated. Then the network performance has been compared with several recent ADHD detection convolutional neural networks in the literature. It has been observed that the proposed network has a promising performance.

Abstract. Band-spectrum noise has been shown to suppress the visual perception of printed letters. The suppression exhibits a specific dependence on the spatial frequency of the noise, and the frequency domain of most effective inhibition has been related to the size of the letters. In this paper, we address two important questions that were left open by previous studies: (1) Is the observed effect specific to text, and which parameters determine the domain of most effective suppression? (2) What is the origin of the effect in terms of underlying neural processes? We conduct a series of psychophysical experiments that demonstrate that the frequency domain of most effective inhibition depends on the stroke width of the letter rather than on the letter size. These experiments also demonstrate that the effect is not specific to the recognition of letters but also applies to other objects and even to single bars. We attribute the observed effect to nonclassical receptive field (non-CRF) inhibition in visual area V1. This mechanism has previously been suggested …

Running title: Cellular heterogeneity of human proximal tubules Funding disclosures: The authors have no connection to companies that have financial interests in the manuscript. ABSTRACT Acute tubular necrosis (ATN), elicited by ischemia and/or toxicity, is a potentially life threatening condition. Histologically, ATN corresponds to necrosis and detachment of renal tubular epithelial cells. However, the tubules possess a considerable regenerative capacity, and may be restored. We have previously identified a scattered population of progenitor like cells within the proximal tubules, sharing marker expression with the parietal epithelial cells of Bowman's capsule as well as with renal tubules regenerating after ATN. In the present analysis, we use transmission electron microscopy, immunoelectron microscopy and immunofluorescence of human kidney cortex to further explore these cells. We demonstrate that the cells are smaller and have drastically fewer mitochondria than the surrounding proximal tubule cells. They also display strong expression of several structural proteins such as vimentin, collagen-7A1 and the tight junction protein claudin-1. To functionally assess these cells, we also developed a novel human kidney explant model of ATN demonstrating that the cells are more resilient to injury than the surrounding proximal tubular cells. Taken together the results suggest a novel robust cell type with a contrasting biological role to that of the bulk proximal tubular epithelium.
Lesion of the subiculum reduces the spread of amyloid beta pathology to interconnected brain regions in a mouse model of Alzheimer ' s disease

Background: The progressive development of Alzheimer’s disease (AD) pathology follows a spatiotemporal pattern in the human brain. In a transgenic (Tg) mouse model of AD expressing amyloid precursor protein (APP) with the arctic (E693G) mutation, pathology spreads along anatomically connected structures. Amyloid-β (Aβ) pathology first appears in the subiculum and is later detected in interconnected brain regions, including the retrosplenial cortex. We investigated whether the spatiotemporal pattern of Aβ pathology in the Tg APP arctic mice to interconnected brain structures can be interrupted by destroying neurons using a neurotoxin and thereby disconnecting the neural circuitry. Results: We performed partial unilateral ibotenic acid lesions of the subiculum (first structure affected by Aβ pathology) in young Tg APParc mice, prior to the onset of pathology. We assessed Aβ/C99 pathology in mice aged up to 6 months after injecting ibotenate into the subiculum. Compared to the brains of intact Tg APP arctic mice, we observed significantly decreased Aβ/C99 pathology in the ipsilateral dorsal subiculum, CA1 region of the hippocampus and the retrosplenial cortex; regions connecting to and from the dorsal subiculum. By contrast, Aβ/C99 pathology was unchanged in the contralateral hippocampus in the mice with lesions. Conclusion: These results, obtained in an animal model of AD, support the notion that Aβ/C99 pathology is transmitted between interconnected neurons in AD.

Purpose This paper aims to investigate how employee–organization relationship (EOR) outcomes – types and qualities – are interrelated and how employees' perceptions of types (exchange and communal EORs) and qualities (trust, satisfaction, commitment, and control mutuality) play a role in their evaluations of symmetrical internal communication (SIC) and employee job engagement (EJE). Design/methodology/approach This study conducted an online survey of full-time employees ( N = 804) from major US industries. This study performed a confirmatory factor analysis to check the validity and reliability of the measurement model using latent variables and then conducted structural equation modeling. Findings The findings demonstrate that employees' perceptions of both exchange and communal EORs are associated with each of the four EOR qualities. The results also show that only communal EORs have a significant relationship with perceived SIC and that employees' perceptions about one of the EOR quality indicator, satisfaction with an organization, has a significant association with their perceived EJE.

COUNTING UPPER INTERACTIONS IN DYCK PATHS

Upper and lower interactions are parameters of Dyck paths which are mo- tivated by corresponding parameters in a model of partially directed polymers. We in- vestigate the problem of obtaining the generating function for Dyck paths with respect to upper interactions in terms of basic hypergeometric q-series in which an algebraic term occurs.

Environmental Economy and Policy Research Discussion Paper Series Trading-off Health Risk and Latency: Evidence from Water Pollution in Bangladesh Trading-off Health Risk and Latency: Evidence from Water Pollution in Bangladesh

The Ganges Delta of Bangladesh faces a major environmental and development problem from arsenic groundwater contamination. Here we address the rural population's health preferences and estimate how much a given risk of arsenicosis would have to be postponed to make that risk acceptable. We also derive implicit rates of time preference associated with this health hazard based on an experimental field study in Bangladesh. Results suggest that households exposed to arsenic contaminated water do trade-off risk against latency of developing arsenicosis. The results can also be interpreted as if households face a time-varying (hyperbolic) pure rate of time preference.
Coronavirus Pandemic Predictors of mortality in hemodialysis patients with COVID-19: A single-center experience

Introduction: The COVID-19 pandemic has disproportionately affected patients with preexisting comorbidities, particularly dialysis patients. The aim of this study was to determine predictors of mortality in this population. Methodology: We conducted an observational, retrospective, cohort study collecting data from pre and post-vaccine from the electronic medical records of a single dialysis center at Hygeia International Hospital Tirana, Albania. Results: Of 170 dialysis patients, 52 were diagnosed with COVID-19. The prevalence of COVID-19 infection in our study was 30.5%. The mean age was 61.5 ± 12.3 years and 65.4% were men. The mortality rate in our cohort was 19.2%. Mortality rates were higher in patients with diabetic nephropathy ( p < 0.04) and peripheral vascular disease ( p < 0.01). Elevated C-reactive protein (CRP) ( p < 0.018), high red blood cell distribution width (RDW) ( p < 0.03), and low lymphocyte and eosinophil counts, were found to be risk factors for severe COVID-19 disease. ROC analysis identified lymphopenia and eosinopenia as the strongest predictors of mortality. After the vaccine administration, the mortality rate in the vaccinated population was 8%, in contrast to the 66.7% mortality rate that was found in the unvaccinated group ( p < 0.001). Conclusions: Our study revealed that risk factors for the development of severe COVID-19 infection were RDW, low lymphocyte and eosinophil counts, elevated levels of CRP. Lymphopenia and eosinopenia were determined as the most important predictors of mortality, in our cohort. Mortality was notably lower among vaccinated patients.
Hydrodynamic interactions are key in thrust-generation of hairy flagella

The important role of unicellular ﬂagellated micro-organisms in aquatic food webs is mediated by their ﬂagella, which enable them to swim and generate feeding currents. The ﬂagellum in many predatory ﬂagellates is equipped with hairs (mastigonemes) that reverse the direction of thrust compared to the thrust due to a smooth ﬂagellum. Conventionally, the mechanism of such reversal has been attributed to drag-based thrust of individual hairs, neglecting their hydrodynamic interactions. However, at natural densities of hairs, hydrodynamic interactions are important. In fact, using fully resolved three-dimensional computational ﬂuid dynamics, we show here that hydrodynamic interactions are key to thrust-generation and reversal in hairy ﬂagellates, making their hydrodynamics fundamentally different from the slender-body theory governing smooth ﬂagella. We reveal the signiﬁcant role of the curvature of the ﬂagellum, and using model analysis we demonstrate that strongly curved ﬂagellar waveforms are optimal for thrust-generation. Our results form a basis for understanding the diverse ﬂagellar architectures and feeding modes of predatory ﬂagellates.
This item is the archived peer-reviewed author-version of: Professionals' views on the development process of a structural collaboration between child and adolescent psychiatry and child welfare : an exploration through the lens of the life cycle model Reference:

This study, as a part of a participatory action research project, reports the development process of an innovative collaboration between child and adolescent psychiatry and child welfare, for adolescent girls with multiple and complex needs. The findings emerge from a qualitative descriptive analysis of four focus groups with 30 professionals closely involved in this project, and describe the evolution of the collaborative efforts and outcomes through time. Participants describe large investments and negative consequences of rapid organizational change in the beginning of the collaboration project, while benefits of the intensive collaboration only appeared later. A shared person-centred vision and enhanced professionals’ confidence were pointed out as important contributors in the evolution of the collaboration. Findings were compared to the literature and showed significant analogy with the life cycle model for shared service centres that describe the maturation of collaborations from a management perspective. These findings enrich the knowledge about the development process of collaboration in health and social care. In increasingly collaborative services, child and adolescent psychiatrists and policy makers should be aware that gains from a collaboration will possibly only be achieved in the longer term, and benefit from knowing which factors have an influence on the evolution of a collaboration project.
Comparative analysis of extreme ultraviolet solar radiation proxies during minimum activity levels

: Four extreme ultraviolet (EUV) solar radiation proxies (Magnesium II core-to-wing ratio (MgII), Lyman α flux ( F α ), 10.7-cm solar radio flux ( F 10.7 ), and sunspot number ( Rz )) were analyzed during the last four consecutive solar activity minima to investigate how they differ during minimum periods and how well they represent solar EUV radiation. Their variability within each minimum and between minima was compared by considering monthly means. A comparison was also made of their role in filtering the effect of solar activity from the critical frequency of the ionospheric F 2 layer, f o F 2 , which at mid to low latitudes depends mainly on EUV solar radiation. The last two solar cycles showed unusually low EUV radiation levels according to the four proxies. Regarding the connection between the EUV “true” variation and that of solar proxies, according to the f o F 2 filtering analysis, MgII and F α behaved in a more stable and suitable way, whereas Rz and F 10.7 could be overestimating EUV levels during the last two minima, implying they would both underestimate the inter-minima difference of EUV when compared with the first two minima.

On the effects of Catalan contact in the variable expression of Spanish future tense A contrastive study of Alcalá de Henares, Madrid and Palma, Majorca

This paper aims to test the influence of Catalan-Spanish bilingualism in the variable distribution of the morphological future (MF) cantaré and the peri-phrastic variant (PF) voy a cantar in Spanish. As Catalan does not have a PF, it has been suggested that in the areas where Spanish coexists with Catalan the MF is relatively more used. A contrastive study of a bilingual community (Palma de Mallorca) and a Spanish monolingual one (Alcalá de Henares) confirms this hypothesis: the frequency of use of the MF among bilinguals is double what it is in a non-contact setting. At the same time, however, the two speech communities yield similar results in regard to the semantic values associated to each of the forms.
Practioner Review: Assessment and treatment of PTSD in children and adolescents

Post-traumatic Stress Disorder (PTSD) is a syndrome deﬁned by the intrusive re-experiencing of a trauma, avoidance of traumatic reminders, and persistent physiological arousal. PTSD is associated with high levels of comorbidity and may increase the risk for additional disorders over time. While controversies remain regarding the applicability of the PTSD criteria to very young children, it has proved to be a useful framework for guiding assessment and treatment research with older children and adolescents. This article presents an overview of the literature on the clinical characteristics, assessment, and treatment of PTSD in children and adolescents.

Fund managers are double agents; they serve both fund investors and owners of management firms. This conflict of interest may result in trading to support securities prices. Tests of this hypothesis in the Spanish mutual fund industry indicate that bank-affiliated mutual funds systematically increase their holdings in the controlling bank stock around seasoned equity issues, at the time of bad news about the controlling bank, before anticipated price drops, and after non-anticipated price drops. The results seem mainly driven by bank managers’ incentives. Ownership of asset management companies thus matters and can distort capital allocation and asset prices.

Fishery and bionomics of tunas at Mangalore

Karnataka waters, on the upper part of S.W. coast of India produce an average total of 786 tonnes of tuna annually (1972-'81) forming 0.7% of the state's marine fish catch and 5 % of the total tuna catch of India. Of late, the production rate of this resource in the state had gone upto an average of 1,729 tonnes per year (1979-81). This rapid progress was achieved by the introduction of modern fishing techniques such as purse seining, deployment of mechanised crafts for drift gill netting and synthetic materials for gears.
during reading in relation to the sulci of

Neurological studies suggest that the angular gyrus region of the inferior parietal lobule may be critical for reading. However, unambiguous demonstration of angular gyrus involvement from lesion and functional neuroimaging studies is lacking, partly because of the absence of detailed morphological descriptions of this region. On the basis of our recent anatomical examination of this region and a tightly controlled functional magnetic resonance imaging paradigm, the present investigation demonstrated reading-related activity in the region of the angular gyrus that lies between the central and posterior branches of the caudal superior temporal sulcus, namely cytoarchitectonic area PG. Analysis of functional connectivity showed increased functional coupling during reading of area PG with the language areas of Broca and Wernicke, and a region previously identified as the visual word form area. Thus, the parietal reading area has been precisely localized, and its interactions with other cortical areas during reading have been demonstrated.
