Watching the Watchmen: Assessment-Biases in Waiting List Prioritization for the Delivery of Mental Health Services
Authors: Kreiseder Fabian , Mosenhauer Moritz 
Published: April 2022

Purpose: While the demand for mental health services increases, supply often stagnates. Providing treatment to those most in need is an important factor in its efficient distribution. We propose and conduct a statistical procedure for detecting rater-biases in patient prioritization tools.
Design / Method / Approach: We gather real-life data from 266 illness severity assessments in an Austrian publicly funded mental health service provider, including a rich set of covariates. To ensure robustness, we merge this data with determinants of mental health and assessment identified by previous research, such as weather or seasonal indicators.
Findings: We find statistically significant effects of rater-biases. These effects are robust to a large array of controls.
Practical Implications: A back-of-the-envelope calculation reveals that the identified rater effects can translate to large changes in the waiting times for patients. Misspecified treatment allocations may lead to worsened symptoms and potentially fatal outcomes.
Originality / Value: Although a growing literature focuses on patient prioritization tools, many articles study these in synthetic contexts using “vignettes”. In comparison, our study adds external validity by considering real-life treatments in the field.
Research Limitations / Future Research: This study can be used as a starting point for deeper, causally focused studies.

Authors: Pasmawati Yanti , Tontowi Alva Edy , Hartono Budi , Wijayanto Titis 
Published: April 2022

Purpose: This research was conducted to analyze the extent to which online customer reviews (OCRs) can stimulate investment backers as a strategy to increase crowdfunding investment.
Design / Method / Approach: This research is quantitative. Natural language processing (NLP) processes review text documents based on linguistic study, a lexicon-based method is used for sentiment analysis classification based on polarity score (pros and cons), while Multiple linear regression forms a model or relationship between online customer reviews and crowdfunding investments. OCRs consisting of numeric and text features were collected from one hundred technology products (3D printing, drones, cameras, wearables) on Kickstarter.com.
Findings: The study results show that, in addition to positive reviews, the number of comments and the number of sentiment reviews can increase consumer interest in investing in technology products on the crowdfunding platform. Moreover, positive reviews have the most positive effect on crowdfunding investments.
Practical Implications: The study results are expected to be used for startup business, especially technology products as a strategy to increase funding investment on a reward-based crowdfunding platform. Startups can take advantage of online customer reviews as one of important factors in stimulating potential backers and backers to invest.
Social implications: The strategy of utilizing online customer reviews can be used especially for technology product-based startup business to get funding support as a resource in completing a product development stage.
Originality / Value: The novelty of this research is that it focuses on a technological product development stage, product campaigns on a reward-based crowdfunding platform, considering online customer reviews through sentimental (online reviews) and numerical characteristics (number of comments, number of sentiment reviews) simultaneously as a strategy to increase investment.
Research Limitations / Future Research: This study has some limitations as it used only online customer reviews as an attribute that affects crowdfunding investment. Future research is expected to explore online customer reviews to determine important attributes (unique words) as consideration for strategies to increase crowdfunding investment.

At the Eleventh Hour. The Principles of Folklore Collection in the Scholarly Oeuvre of Lajos Katona and in Hungarian Folklore Studies at the Turn of the 20th Century
Authors: Landgraf Ildikó 
Published: April 2022

Abstract
In Hungary, the academic study of folklore started at the turn of the 20th century. In the period between 1889 and 1920, institutions for the study of folklore and ethnography were established. The author points out that ethnographic collections in this era were motivated by concern about the loss of folk culture phenomena owing to changes brought by modernisation. Major arguments for the establishment of the Hungarian Ethnographic Society as well as the Museum of Ethnography referred to the need to salvage endangered items of folk culture from vanishing. Folklore collections were interpreted as rescue missions aiming to save material in the penultimate moment. The author of this paper investigates the way in which an outstanding folklorist of the period, Lajos Katona (1862–1910), professor of comparative literary studies, defined the essence, purpose, and method of ethnographic/folklore collections. Katona urged on several occasions that collectors of folklore be equipped with professional guidebooks and other auxiliary materials. He played a role in the popularisation of the activities of the Folklore Fellows, furthering the establishment of a network of voluntary collectors. Empirical data collection in the field is a central notion of folklore studies, one of the most important methodological and epistemological categories of the discipline, which functions as a distinctive feature differentiating it from other fields of study. Therefore, it is of central importance to shed light upon how and why the principles of the collection and recording of folklore phenomena in oral culture have changed.
Gas reserves calculation based on the results of reservoir pressure distribution modeling
Authors: Zakharchuk Oksana 
Published: April 2022

The object of this study is the gas-bearing layer B-26 of the Zakhidne-Radchenkivsʹke gas condensate field (Ukraine). A bottleneck in the process of exploration and experimental and industrial operation of the Zakhidne-Radchenkivsʹke gas condensate field was the ambiguous data on extractive reserves (values that were calculated by different authors range from 14 thousand to 424 million m3). At present, the field is mothballed, which is why the use of a new approach to calculating the initial gas reserves could be useful for deciding to start developing a single productive layer B-26.
During the study, such theoretical research methods were used as the system analysis of the information used, numerical modeling based on the combined finite-element-difference method, the methods of visual representation of the information received, as well as analytical methods. The method of calculating gas reserves proposed in this work combines a volumetric method and the simulation of filtration processes using a combined finite-element-difference method. The latter makes it possible to take into consideration the structure of the reservoir, which is heterogeneous in terms of permeability, and to adequately, at the quantitative level, to describe the distribution of non-stationary reservoir pressure around the extractive well. By applying an analytical formula based on the values of average reservoir and downhole pressures, the radii of the well's feed circuit at different stages of the reservoir development have been calculated. Thus, the active area (and volume) of the reservoir can be determined, according to which the extractive reserves of the deposit are calculated. The mining reserves of the Zakhidne-Radchenkivsʹke field, estimated in this way, amount to 174 million m3 of gas.
The method for calculating reserves proposed in this study could prove useful for deciding on the further development of the Zakhidne-Radchenkivsʹke gas condensate field. Combining the volumetric method with the results of modeling filtration processes is an operational method for calculating the reserves of the reservoir, opened by one mining well. In this case, the application of the combined finite-element-difference method makes it possible to take into consideration the complex heterogeneous structure of the reservoir and predict the distribution of reservoir nonstationary pressures around the extractive well.
The current study that used the Zakhidne-Radchenkivsʹke gas condensate field in Ukraine as an example is interesting when calculating the reserves of layers of complex structure all over the world, whereby the productive reservoir is opened by a single mining well.
Therapeutic Yoga for the Management of Chronic Nonspecific Neck Pain: Current Evidence and Mechanisms

Published: April 2022

Abstract
Chronic nonspecific neck pain (CNNP), which is neck pain in the absence of attributable structural and neurological findings, is often challenging for medical and rehabilitation professionals to treat. Conventional treatments such as medications and physical therapy often fail to provide lasting relief, which leads patients to pursue complementary therapies such as yoga. This review discusses the evidence from nine studies, including four randomized controlled trials, which suggests that a supervised yoga program may decrease pain intensity, disability, and mood symptoms in adults with CNNP. Cervical range of motion and quality of life (both physical and mental) may also improve with yoga intervention, although this is less consistent across studies. Evidence of yoga’s superiority to other exercise-based practices such as pilates was conflicting. Adverse effects of yoga, such as exacerbation of neck pain, were relatively uncommon, minor, and often transient. This article also comprehensively reviews the pathophysiology of CNNP, therapeutic mechanisms of yoga, and limitations in the evidence (including risk-of-bias assessment). Future studies should attempt to: (1) compare the effectiveness of different lineages of yoga for individuals with CNNP, (2) determine the optimal length and duration of these yoga interventions, (3) better characterize the physical and psychological mechanisms of yoga, (4) compare yoga to other exercise- and mindfulness-based practices, (5) evaluate the effect of yoga on sleep in the CNNP population, and (6) explore the applicability/efficacy of virtual yoga instruction.

Purpose: to analyze the results of the treatment recurrent «inferior» retinal detachments (RD) depending on the volume of surgical intervention.Patients and methods. 81 patients (81 eyes) with recurrent «inferior» RD were included in this retrospective study. Groups were identified depending on the volume of surgical treatment of recurrents RDs: scleral buckling (SB), pars plana vitrectomy (PPV), combined surgery: PPV with SB, PPV with retinotomy (RT), including the use of perfluorocarbon fluid (PFCL). The volume of surgical treatment was assessed before recurrent RD, after the first and second recurrent «inferior» RD, the distribution of the grade and type of proliferative vitreoretinopathy (PVR) complicating these recurrents RD with different treatment tactics, analyzed the functional results and anatomical success (retinal reattachment) after surgical treatment of the first and second recurrents RD.Results. Primary anatomical success was achieved in 304 from 385 patients (79 %). In 81 cases, the first recurrent RD was detected (21 %). Surgical treatment of the first recurrent RD included: in 39 cases (48 %) — PPV; in 9 cases (11 %) — PPV with SB; in 13 cases (16 %) — PPV with RT. In 20 cases (25 %) for short-term tamponade with PFCL was used when performing PPV with RT. The second recurrent RD occurred in 42 cases, which accounted for 52 % of the first recurrent RD. The anterior type of PVR was in all cases (100 %). All patients underwent repeated surgery: PPV (100 %), of which in 15 cases (35.7 %) — PPV with RT; the use of short-term postoperative tamponade with PFCL was in 18 cases (42.9 %); additional SB — in 9 cases (21.4 %). Anatomical success was achieved in 100 % of cases after surgical treatment of the second recurrent RD, but in 8 cases (19 %) a retinal redetachment occurred.Conclusion. The increase in PVR continues to be the main cause of recurrent RD. In patients with recurrent «inferior» retinal detachments, grade C PVR type 4, 5, the additional use of SB for PPV, RT and the use of PFCL as a short-term postoperative tamponade allows achieving better results (functional and anatomical). During surgery of the second recurrent RD, when there are pronounced changes in the retina, performing SB is impractical, the alternative is RT.

Authors: Denisova E. V. , Kuzin A. V. 
Published: April 2022

Alkaptonuria is rare autosomal recessive multisystem disease, caused by mutations in the homogentisine oxidase gene, which leads to the deposition of metabolites of homogentisic acid in organs and tissues (ochronosis).The purpose: to study spectrum of ophthalmic manifestations of alkaptonuria in Russian cohort of patients of different ages.Material and methods. Ophthalmological examination of 9 patients: 5 adults aged from 39 to 64 years and 4 children aged from 3 to 6 years with confirmed diagnosis of “alkaptonuria” was performed.Results. In all adult patients bilateral brown-black scleral pigmentation and yellow-brown deposits in the conjunctiva in the region of the palpebral fissure were detected paralymbally, the severity of which correlated with age, tortuosity and vasodilation of the conjunctiva in areas of deposits. In 1 out of 4 children minimal deposits of yellow pigment were found in the conjunctiva of the limb. In patients older than 60 years typical small brownish deposits were observed in the cornea near the limb in the region of the palpebral fissure.Conclusion. Eye changes are one of the most common clinical manifestations of alkaptonuria. Typical manifestations are the sclera’s pigmentation, conjunctiva and cornea in the limb. Ophthalmological examination is non-invasive informative method that can help in early diagnosis, differential diagnostics, assessment of the dynamics of the disease and the effectiveness of the therapy.

Purpose: The vitreous body (CT), due to the complexity of its structure, remains one of the least studied anatomical structures to this day. In the literature there are attempts to describe the anatomy of the vitreous body, since the II century. The most relevant works are the studies of J. Worst et al. in 1973, in which the authors proposed new methods of CT preparation with the introduction of dyes. Despite many years of research on the structure and functions of the vitreous body and the presence of a large number of works, and there are no methods and protocols for macromicroscopic examination of the vitreous body to develop a method and propose a protocol for macromicroscopic examination of the vitreous body (VB), allowing to obtain new data on VB topographic anatomy.Materials and methods. The proposed method of macromicroscopic examination was used to study the VB topographic anatomy of 38 cadaver eyeballs. In order to color transparent structures of the vitreous, poorly soluble metallic salts (barium sulfate and copper acetate) were used. Macroscopic examination was performed using a Topcon OMS-800 operating microscope with a magnification of ×8 to ×21, microscopic changes were evaluated by light microscopy at ×50, ×100, ×200, ×400, ×630 multiple magnification with Leica DM LB2 microscope followed by photographic recording. The algorithm for macroscopic examination performing.Results and discussion. The result of macroscopic preparation was the compilation of individual anatomical and topographic maps of patients. A distinctive feature of the developed method is the ability to dissect any VB structure and to isolate each cortical layer with the possibility of studying its anatomical and topographic features and relationships with underlying tissues (internal limiting membrane, ciliary body, lens capsule). In addition, the method allows to maintain the shape and integrity of the specimens after passing through all stages of histological processing. In order to fixate VB samples, we used a method with fixing VB structures on a special adhesive-metric tablet, and placing them in a biopsy bag placed in a biopsy cassette. After that, filled in formalin, the specimens were delivered to the laboratory, where all the stages of standard processing took place.Conclusion. The developed technique of macromicroscopic examination of the vitreous allows to create an individual map of the VB topographic anatomy. After collecting of sufficient material and its statistical processing, it is possible to provide maps of the VB topographic anatomy in normal, age-related and pathological conditions.

Purpose. Scientific substantiation of methodological approaches to the development of a “quality of life” (QoL) questionnaire after cataract phacoemulsification (PEC) in patients with visually stressful work (VLT), based on a “medico-social” health model.Methods. The study was carried out on the basis of methodological standards for the development of new tools for assessing symptoms in clinical medicine developed by specialists from the International Center for the Study of Quality of Life (St. Petersburg). This article presents the first stage of development aimed at the formation of a preliminary version of the questionnaire. The initial volume of questions (complaints) of the patient was carried out in the following areas: individual interviews (according to the standard developed methodology) with 50 patients with ZNT; analysis of proven methods for studying QOL in cataracts (“NEI-VFQ”, “Cataract Symptom Scale”, “Catquest-9SF”, etc.); analysis of proven methods for studying QoL in keratorefractive surgery and asthenopic conditions in patients with RNT; analysis of the classification structure of the International Classification of Functioning (ICF) from the standpoint of the development of characteristic “domains”.Results. The data obtained indicate that a total of 35 patient complaints were identified (7 — “visual”; 6 — “professional”; 16 — “functional”; 4 — “household”; 4 — “medical and psychological”). The fundamental difference between the development of the methodology for assessing the patient’s QoL after performing PE is the use of a “social model” of health, which confirms the leading (46 % of all complaints) place for “functional” manifestations of the patient’s subjective status, based on specific “domains” of the ICF. Along with this, the practical application of the basic provisions of the ICF involves scaling the severity of the patient’s complaints in the context of the ratio of the duration of the complaint to the total active time of the patient with a gradation: “Mild problems” (5–24 %); “Moderate problems” (25–49 %); “Severe problems” (50–95 %); “Absolute problems” (96–100 %).Conclusion. The results of the first stage of the development of the patient’s QoL questionnaire after the FEC testify to the compliance with clinical standards in terms of content validity, since the questions, scales and general content reflect the significance for the patient and important parameters from a clinical and functional point of view. A distinctive feature and scientific novelty of the questionnaire is the use of a “social model” of health based on the development of “domains” of the international classification of functioning, as well as optimization of the procedure for scaling patient responses.

This article presents the third part of an experimental study on the prospects and possibilities of using quantum dots and bioconjugates created on their basis in the treatment of inflammatory diseases of the eye. Taking into account the previously obtained results on the possibility of “safe” use of CdTe/Cd and InP/ZnSe/ZnS quantum dots on an animal model under conditions of intravitreal administration, theaimof the current stage was to analyze their antimicrobial activity in a bacteriological laboratory.Materials and methods.As QDs, we took two types of artificial fluorophores capable of generating superoxide radicals synthesized according to a special technical assignment at the Federal State Unitary Enterprise “Research Institute of Applied Acoustics”, Dubna, Moscow Region: type 1 — colloidal solution of QD CdTe / Cd MPA 710 10 % of the mass. Type 2 — colloidal solution of QD InP / ZnSe / ZnS 650 10 % wt. The study included “museum” and nosocomial strains of microorganisms, and the activity of points was assessed using the diskdiffusion method, followed by an assessment of the zones of inhibition of bacterial growth. Concentrations of 0.1 %, 0.01 %, and 0.001 % quantum dots were tested, as well as solutions of bioconjugates (antibiotic + quantum dots) of Vancomycin, Levofloxacin, Ceftazidime and Cefotaxime.Results.Based on the data obtained, it was concluded that quantum dots potentiate the action of the sensitivity of individual microorganisms, both outpatient and hospital strains.
