Objetivo. Establecer la utilidad de los índices de vascularización cervical en la predicción de parto pretérmino inminente. Diseño. Estudio de casos-controles. Institución. Hospital Central “Dr. Urquinaona”, Maracaibo, Venezuela. Participantes. Pacientes con parto pretérmino en los siguientes 7 días (grupo A) y embarazadas con parto pretérmino más allá de los 7 días (grupo B). Métodos. Las embarazadas fueron evaluadas utilizando ecografía transvaginal y seguidas hasta el parto. Principales medidas de resultado. Características generales, índices de vascularización cervical (índice de vascularización, índice de flujo e índice de vascularización / flujo), parto pretérmino inminente y eficacia pronóstica. Resultados. Fueron incluidas 350 pacientes, 75 mujeres presentaron parto pretérmino inminente (grupo A) y 251 pacientes fueron consideradas como controles (grupo B). Las pacientes del grupo A tuvieron valores significativamente más bajos del índice de vascularización e índice de flujo comparado con el grupo B (p = 0,0122 y p < 0,0001, respectivamente). Las pacientes del grupo B presentaron valores significativamente más altos de índice de vascularización / flujo comparadas con las pacientes del grupo A (p = 0,0103). Los tres índices y la combinación de estos no mostraron capacidad de discriminación de parto pretérmino inminente. Conclusiones. Las pacientes con parto pretérmino inminente presentan diferencias significativas en los índices de vascularización comparado con las pacientes que presentan parto pretérmino más allá de los 7 días de la evaluación ecográfica. Sin embargo, no son útiles en la predicción del parto pretérmino inminente.

Introducción. Potenciar la participación de las mujeres durante el embarazo y el parto se alinea con el llamado de la Organización Mundial de la Salud y se vincula con efectos en la satisfacción usuaria, resultados clínicos de salud y una mejor gestión de los prestadores de salud. Objetivo. Descubrir las necesidades de participación en la toma de decisiones de las mujeres durante el proceso del embarazo y parto. Método. Análisis secundario de un estudio cualitativo descriptivo con mujeres hospitalizadas del servicio de puerperio de dos hospitales en Santiago de Chile. El análisis de los datos se realizó utilizando el método propuesto por la Grounded Theory. Resultados. Participaron doce mujeres en dos grupos focales. Del análisis relacional se desprende que la participación en el proceso reproductivo es interferida por dos grupos de factores vinculados a significados culturales y a la vulneración de los derechos de las mujeres. Conclusiones. La participación de las mujeres en las decisiones clínicas durante el proceso de embarazo y parto es aún escasa y el poder sigue manteniéndose en los profesionales de la salud, perpetuándose prácticas de violencia institucional. Para avanzar en una práctica obstétrica centrada en las mujeres, es importante reconocer el papel activo que ellas quieren y pueden cumplir para vivir una experiencia positiva y satisfactoria.

Published: September 2022

Fast and accurate identification of cardiac devices can facilitate device programming and interrogation in various medical settings. We have previously demonstrated the accuracy of the PacemakerID machine learning algorithm for mobile phone cardiac device identification. However, the questions of the reproducibility of this algorithm and whether a single trial sufficiently maximizes accuracy have yet to be answered. Here, we examine 502 chest x-rays performed at a single institution on patients with implantable cardioverter-defibrillators and permanent pacemakers. The PacemakerID mobile phone application was used for five sequential trials on each image and the accuracy of one, three, and five trials were compared. A single trial resulted in a 79% accuracy and 82% positive predictive value with no significant difference (p=0.69) as compared to five trials at identifying device manufacturers. Across all devices, the results of a single trial were not significantly different from those of five trials. Our data demonstrate that a single trial is sufficient to maximize diagnostic accuracy with the PacemakerID mobile phone application, facilitating rapid identification for prompt programming and interrogation of cardiac devices.
Data Collection And Processing System Design For Lithium Based Batteries
Authors: YILDIRIM DALKIRAN Fatma , KAYA Yusuf
Published: September 2022

With basic definition, batteries are energy storage systems that convert chemical energy into electrical energy. The usage areas of batteries are increasing day by day. The rapid development of mobile technologies in every field has increased the importance of storage systems with high energy density, low volume, and weight. Until 1990, lead acid, Ni-Cd and Ni-MH storage systems were used extensively. However, rapid technological developments in the field of mobile telephony have revealed the need for lighter and higher energy density batteries. Li-Ion batteries have revolutionized mobile devices in this area, and these batteries have spread rapidly in every field where mobility is important. On the other hand, they also caused concern with their dangerous aspects and a series of precautions had to be taken in their use. In order to determine the precautions, the data of the Li-Ion batteries in use should be collected and evaluated. In this study, battery data during charging and discharging by setting up experimental setup were collected and processed. In addition, data of batteries operating under different electrical and temperature conditions were collected. The collected data were used to determine battery performance and calculate capacity level.
On causes and mechanisms of appearance of mini polymerous Hymenolepididae (Cyclophyllidea, Cestoda), parasites of shrews
Authors: Gulyaev V.D. , Kornienko S.A.
Published: September 2022

The direction of the morphological transformations in the phylogenesis of Hymenolepididae from shrews depends on the nature of dissemination of hexacanths in the external environment. The organization of strobila and proglottids in Neoskrjabinolepis Spassky, 1948 and Lineolepis Spassky, 1958 which have hexacanths going out into the external environment inside the segment-oophor is determined by the group dissemination of hexacanths. At the group dissemination of hexacanths the probability of infection for intermediate hosts depends on their number in the external environment rather than on the fertility of individual proglottids. The nonselective group elimination of free-living larvaе in the external environment results in a higher rate of strobilation, number of proglottids in the strobila and low fertility of proglottids in Neoskrjabinolepis and Lineolepis. However the polymerous strobila of Neoskrjabinolepis and Lineolepis is formed under the obligate high density of infrapopulations in the intestine of small-sized hosts. In turn the selection for miniaturization of the polymerous strobila predetermines heterochronic reorganizations of these cestodes. The acceleration of morphogenesis of the genitals is the evolutionary mechanism of juvenilization of mature proglottids of Neoskrjabinolepis and Lineolepis which leads to a significant decrease in their size and change in their form. The heterochronic reorganizations in the genitals of the strobila are in turn accompanied by coordinated changes in the form and size of gonads in mature proglottids. A considerable fall in fertility (the number of hexacanths) of proglottids in Neoskrjabinolepis and Lineolepis is caused by these changes too.
Spiny-headed worms (Acanthocephala) in the basin of the Sea of Okhotsk: taxonomic and ecological diversity
Authors: Atrashkevich G.I.
Published: September 2022

For the first time the inventory of the taxonomic composition of the spiny-headed worms has been carried out in the basin of the Sea of Okhotsk. It has revealed their high biodiversity. We have registered 100 species and forms of 28 genera of 17 families of 8 orders of 3 classes in composition of the phylum Acanthocephales. Spiny-headed worms of hydrotopic species, both sea and freshwater, totally dominate in the basin of the Sea of Okhotsk. Parasitic systems of the background species of the sea spiny-headed worms are basically composed by the dominant species of intertidal and near-shore sea amphipods, and besides of decapods as intermediate hosts. Structure and biotopic belonging of parasitic systems of the freshwater spiny-headed worms species in the region are determined by the freshwater crustaceans belonging to ostracods of genera Cypria and Candona, amphipods of the genus Gammarus and isopods, namely water slaters of the genus Asellus. Broad transmission of the spiny-headed worms within certain ecosystems and over the basin of the Sea of Okhotsk is realized by their definite and parathenic hosts. Short- and long-distance migrant fishes, birds and mammals are most important among them.

Introduction. Kremenchuk reservoir plays an important role for waterbirds and wetland birds during seasonal migrations. Therefore, we provide the monitoring of the avifauna during seasonal migrations in the central part of the reservoir. The article details the results of the wetland birds and waterbirds censuses in the spring periods of 2014-2016.Purpose. To assess the species composition of wetland birds and waterbirds, their relative numbers, and seasonal dynamics in the spring period in the central part of the Kremenchuk reservoir. To compare the results with those obtained during 2007-2013.Methods. Bird censuses were conducted along the dam through the Kremenchuk Reservoir. Used the route-point method of censuses. In total 17 bird censuses were conducted (5-6 each year).Results. During the period of studies, 36 species of waterbirds and wetland birds were detected. The most numerous migratory species were Anser albifrons, Anas plathyrhynchos, A. penelope, Aythya fuligula, and Larus cachinans. Another 7 species can be considered common (Phalacrocorax carbo, Cygnus olor, Anser fabalis, Bucephala clangula, Fulica atra, Larus ridibundus, and L. canus). Five identified species are listed in the Red Data Book of Ukraine (Cygnus bewickii, Anas strepera, Bucephala clangula, Haliaeetus albicilla, and Haematopus ostralegus). The highest number of birds was observed in the second and third decades of March.Originality. Our data supplement the information on the species composition of wetland and waterbirds, their number, and dynamics in the central part of the Kremenchuk reservoir in the spring. The greatest impact on the number of birds at the local level have temperature, the area of ice cover, the water level in the reservoir.Conclusions. The central part of the Kremenchuk reservoir plays an important role for migratory waterbirds and wetland birds. A significant number of these birds (from 5 to more than 20 thousand) use this area for rest and feeding during the period of the spring migration. The most important for these birds part of the studied area is the water area of the Ornithological Reserve "Lypivskiy".Key words: migration, number, migration waves, phenology.

OBJECTIVE

Spinal meningiomas pose unique challenges based on the location of their dural attachment. However, there is a paucity of literature investigating the role of dural attachment location on outcomes after posterior-based approach for spinal meningioma resection. The aim of this study was to investigate any differences in outcomes between dural attachment location subgroups in spinal meningioma patients who underwent posterior-based resection.

METHODS

This was a single-institution review of patients who underwent resection of a spinal meningioma from 1997 to 2017. Surgical, oncological, and neurological outcomes were compared between patients with varying dural attachments. Multivariate analysis was utilized.

RESULTS

A total of 141 patients were identified. The mean age was 62 years, and 110 women were included. The sites of dural attachments were as follows: 16 (11.3%) dorsal, 31 (22.0%) dorsolateral, 17 (12.1%) lateral, 40 (28.4%) ventral, and 37 (26.2%) ventrolateral. Most meningiomas were WHO grade I (92.2%) and in the thoracic spine (61.0%). All patients underwent a posterior approach for tumor resection. There were no differences between subgroups in terms of largest diameter of tumor resected (p = 0.201), gross-total resection (GTR) or subtotal resection (p = 0.362), Simpson grade of resection, perioperative complications (p = 0.116), long-term neurological deficit (p = 0.100), or postoperative radiation therapy (p = 0.971). Cervical spine location was associated with reduced incidence of GTR (OR 0.271, 95% CI 0.108–0.684, p = 0.006) on multivariate analysis. The overall incidence of recurrence/progression was 4.6%, with no difference (p = 0.800) between subgroups. Similarly, the average length of follow-up was 28.1 months, with no difference between subgroups (p = 0.413).

CONCLUSIONS

Posterior-based approaches for resection of spinal meningiomas are safe and effective, regardless of dural attachment location, with similar surgical, oncological, and neurological outcomes. Comparison of long-term recurrence rates between dural attachment subgroups is required.

Published: September 2022

OBJECTIVE

Dural ossification (DO) is a common clinical feature in patients with thoracic ossification of the ligamentum flavum (OLF) and associated with the increased risk of perioperative complications. However, few studies have been conducted to determine the incidence and independent risk factors of DO in patients with thoracic OLF. The aim of this retrospective study was to determine the incidence and independent risk factors of DO in patients with thoracic OLF.

METHODS

A total of 107 patients with thoracic OLF who were admitted to the authors’ hospital from December 2020 to December 2021 were included in this study. The independent risk factors of DO in patients with thoracic OLF were determined through univariate analysis followed by multivariate logistic regression analysis with p < 0.05. The diagnostic efficacy of the DO in OLF (DO-OLF) risk classification model was determined on the basis of independent risk factors and evaluated on the basis of sensitivity, specificity, and agreement rate.

RESULTS

The incidence of DO in patients with thoracic OLF was 35% (37/107 patients). The tuberous type according to the Sato classification (OR 9.75, p < 0.01) and larger (≥ 9°) supine local kyphosis angle (LKA) (OR 8.13, p < 0.01) were two independent risk factors of DO in thoracic OLF. The DO-OLF risk classification, a novel approach for the diagnosis of DO in patients with thoracic OLF, was established on the basis of the combination of the tuberous type according to the Sato classification and larger supine LKA. The sensitivity, specificity, and agreement rate of this approach for distinguishing between patients with thoracic OLF at high and low risk of DO were 87%, 93%, and 91%, respectively.

CONCLUSIONS

The incidence of DO in patients with thoracic OLF was 35%. The tuberous type according to the Sato classification and larger supine LKA (≥ 9°) were independent risk factors of DO in patients with thoracic OLF. The novel DO-OLF risk classification approach could serve as an efficient method for predicting DO in patients with thoracic OLF.

Published: September 2022

OBJECTIVE

Vestibular and ocular motor dysfunction occurs in an estimated 60%–90% of concussion patients. The Vestibular/Ocular Motor Screening (VOMS) tool is validated for use in concussion patients older than 9 years. The goal of the current study was to adapt the current VOMS tool for a pediatric sample of children aged 5–9 years and establish its clinical utility in this patient population.

METHODS

In this case-control study, 80 symptomatic concussion patients (n = 33 [41%] female) aged 5–9 years (mean age 7.40 ± 1.09 years) and 40 (n = 18 [45%] female) age- and sex-matched uninjured controls (mean age 7.10 ± 1.26 years) completed the VOMS–Child (VOMS-C), a version of the VOMS adapted for younger patients. Differences in binary "yes" or "no" symptom provocation for headache, dizziness, and nausea/"tummy ache" across the 7 items of the VOMS-C, and near point of convergence (NPC) distance, were examined. Logistic regression (LR) models were built to classify concussion and controls. Predicted probabilities were generated from the LR model and entered into receiver operating characteristic (ROC) curve models to generate area under the curve (AUC) values.

RESULTS

VOMS-C item provocation ranged from 13% to 30% for concussed patients and 3% to 20% for controls. The LR model distinguished concussed participants from controls (R2 = 0.39; p < 0.001), with significant predictors being smooth pursuits, family depression history, and NPC distance. The ROC analysis had an AUC of 0.81 (95% CI 0.73–0.89; p < 0.001) in the good range.

CONCLUSIONS

Accurate diagnosis of concussion in the clinic setting requires comprehensive evaluation in multiple domains, including detailed clinical interview, neurocognitive testing, and vestibular/ocular motor assessment, regardless of patient age. Our results provide preliminary support for the VOMS-C as a developmentally appropriate tool for concussion management.

Published: September 2022

Purpose: to study the current state of water resources of the Bolshoy Egorlyk and Western Manych river basins used for irrigation purposes. Materials and methods: on the basis of modern research methods using statistical data, an analysis of runoff volume used for land irrigation and the volume of recirculated water from irrigation to natural surface water bodies of the Bolshoy Egorlyk and Western Manych rivers was made. Results. The analysis carried out showed that the largest water withdrawals from the river basins are made in June-July. On the section of the river Bolshoy Egorlyk from the Novotroitskoe reservoir to the border of the Rostov region and the Stavropol Territory, the total water withdrawal is 103.66 million m³/year, the main water consumers are irrigation and pond fish farming. From the border of Rostov region and Stavropol Territory to the mouth, water is withdrawn from surface sources only for irrigation. Water withdrawal on the site on the Western Manych river from the Novomanychskaya dam to the Proletarsky waterworks for irrigation needs is currently not being produced. The total water withdrawal from the Western Manych river from the Proletarsky to the Veselovsky waterworks is 256.14 million m³/year, the main water consumption is for irrigation. Conclusions. The current state of water resources of the Bolshoy Egorlyk and Western Manych rivers used for irrigation of agricultural land, is characterized as satisfactory. An increase in the level of irrigation development is possible during modernization and reconstruction of irrigation systems and structures, the installation of protective coatings to eliminate seepage losses, as well as equipping structures with water distribution automation systems and hydrometric devices.
1933 Arctic Expedition on the Icebreaking Steamer A. Sibiryakov: Personal Diary of the Microbiologist B. L. Isachenko
Authors: Brovina Alexandra
Published: September 2022

In 1933, a scientific expedition to the northern Kara Sea on the icebreaking steamer A. Sibiryakov was conducted, organized by the All-Union Arctic Institute. Among the expedition participants was the founder of Russian marine and geological microbiology, Academician B. L. Isachenko (also spelled Issatschenko), who kept a personal diary during the expedition. This article analyzes this valuable historical source that contains the descriptions of various events that occurred during the expedition and Isachenko’s opinion on these events as well as his reflections on the optimal forms of organizing Arctic expeditions. The diary also sheds light on the inner world of the scientist who found himself in the extreme working conditions. The results he obtained during the expedition lead to the conclusions about the global human impact and future immense burden on the Arctic ecosystem.
Active Volcanoes, Active Imaginations: Fire-Spitting Mountains and Subterraneous Roars in the German Territories in the Summer of 1783
Authors: Kleemann Katrin
Published: September 2022

In the summer of 1783, a sulphuric, dry fog that lasted for several weeks covered much of Europe. As a result, the sun, moon and other celestial objects appeared 'blood-red'. Speculation in Europe was rife as to the cause of this unusual weather. In Iceland, the Laki fissure had erupted; from June 1783 to February 1784, it released the greatest volume of lava of any eruption on planet Earth in the last millennium. The ejected gases travelled to Europe and beyond via the jet stream. Unaware of the Icelandic eruption, some contemporaries from the German Territories hypothesised that the dry fog emanated from a local source, namely one or more supposed German volcanoes. This paper traces the reports of these 'eruptions' from the perspective of environmental history and presents translations of pertinent newspaper articles that have, for the most part, remained unstudied, in order to evaluate the possible reasons for the emergence of this idea.
Maize is Life! Maize Production and Environmental Transformation in Wartime Rhodesia: 1965-1979
Authors: Kwashirai Vimbai
Published: September 2022

This research examines linkages in maize production, the liberation struggle and environmental transformation in Rhodesia, now Zimbabwe, 1965-1979. The paper is about discourses on rural livelihoods and ecological transformation in times of crises. It uses the case study research strategy to examine wartime production of the staple maize in ten communal areas of Mount Darwin District by the Korekore people, part of the Shona ethnic group, the largest in Zimbabwe. To a large extent, the Korekore depended on maize-dominated diets and incomes. Their maize economy had far-reaching environmental ramifications in the form of deforestation and soil erosion leading to loss of biodiversity. This was at a time when the entire Mount Darwin District was the epicentre of fourteen years of, at first, low intensity warfare followed by widespread intensive and extensive rural-based guerrilla fighting, which altered maize based livelihoods and the environment. Mount Darwin District offers the best opportunity to analyse how maize farming, war and ecology interacted, because the war of independence not only began in this region in 1965, but the Korekore bore the brunt of the fighting - including confinement in several so called protected villages, keeps or makipi. Maize production was steady during the first phase of the war, 1965-72, but its potential for growth was hamstrung and disrupted with the intensification of conflict, 1973-79. While maize agriculture remained a key livelihood strategy, its continuous cultivation on the same fields resulted in environmental degeneration.
The History of the Anthropocene: Meanings and Research Trajectories
Authors: Luciano Eugenio
Published: September 2022

Over the past two decades, the Anthropocene has become a concept of multidisciplinary interest and research. A topic of particular interest has been the history of the Anthropocene. The underlying ambiguity of this topic opens it up to four different meanings, each engendering a discrete research trajectory within the emerging field of Anthropocene studies. The present contribution maps these four research trajectories stemming respectively from geology, Earth system science, environmental history and conceptual history. It also explores ways in which these histories overlap, complement or conflict with one another in understanding the global phenomenon that the Anthropocene represents. As the concept of the Anthropocene grows into a social, political and even educational vehicle for environmental communication, organising knowledge in and of the Anthropocene is an urgent task. This task requires going outside disciplinary comfort zones and engaging with neighbouring as well as distant disciplines with curiosity so as to disclose the full potential of the Anthropocene concept.

SECL: Sampling enhanced contrastive learning
Authors: Tang Yixin , Cheng Hua , Fang Yiquan , Cheng Tao
Published: September 2022

Instance-level contrastive learning such as SimCLR has been successful as a powerful method for representation learning. However, SimCLR suffers from problems of sampling bias, feature bias and model collapse. A set-level based Sampling Enhanced Contrastive Learning (SECL) method based on SimCLR is proposed in this paper. We use the proposed super-sampling method to expand the augmented samples into a contrastive-positive set, which can learn class features of the target sample to reduce the bias. The contrastive-positive set includes Augmentations (the original augmented samples) and Neighbors (the super-sampled samples). We also introduce a samples-correlation strategy to prevent model collapse, where a positive correlation loss or a negative correlation loss is computed to adjust the balance of model’s Alignment and Uniformity. SECL reaches 94.14% classification precision on SST-2 dataset and 89.25% on ARSC dataset. For the multi-class classification task, SECL achieves 90.99% on AGNews dataset. They are all about 1% higher than the precision of SimCLR. Experiments show that the training convergence of SECL is faster, and SECL reduces the risk of bias and model collapse.

Published: September 2022

Coral reefs need strong management and protection efforts. However, public awareness and legal instruments concerning coral reefs are still insufficient. An ecosystem service model perspective is needed for the optimum management of that ecosystem. This study examined the relationship between ecosystem services management in international, national and local environmental laws and the coral reef ecosystem. An analytical descriptive qualitative method with the environmental services model and statutory regulation approaches was used. The researcher found a good relationship between the ecosystem services management in the international, national and local environmental laws and the policy planning concerning the sustainable development of the coral reef ecosystem. However, not all of the existing regulations support the environmental services model. It is because the regulatory framework is not complete, and existing norms do not support the efforts to improve people’s welfare.
A multi-frequency electromagnetic vibration energy harvester based on ferrofluid
Authors: Chen Long , Wang Siqi , Yuan Fang , Li Decai
Published: September 2022

A multi-frequency planar electromagnetic generator is proposed to harvest energy from low-frequency vibrations efficiently in a wide frequency range. The vibration energy harvester is composed of two single-degree-of-freedom resonant systems with different natural frequencies. Two permanent magnets are used as single-degree-of-freedom spring mass to respond to external vibrations, and controlled by another permanent magnet with magnetic attraction. In addition, ferrofluid adsorbed on the poles of two moving permanent magnets can reduce the damping significantly to improve the utilization of low-frequency micro vibrations. Experiments show that, during human walking and jogging, the fabricated generator can obtain 1.3718 mW and 1.4227 mW output power, respectively.
The cardiac autonomic control system response to vestibular stimulation in subjects with BPPV compared with healthy controls
Authors: Kalderon Liran , Chaimoff Moshe , Katz-Leurer Michal
Published: September 2022

BACKGROUND: Vestibulo-sympathetic reflexes (VSR) demonstrate the autonomic interaction between the vestibular system and the cardiovascular system, however little is known about this interaction in patients with benign paroxysmal positional vertigo (BPPV). Although the main complaint of patients with BPPV is vertigo, additional symptoms such as nausea and sweating raise questions whether patients with BPPV have impaired VSR. OBJECTIVE: The aim of this study is to assess the cardiac autonomic control system (CACS) response to vestibular stimulation in subjects with BPPV compared with healthy controls. METHODS: This is a case-control study. Heart-rate variability (HRV) parameters were monitored in two groups (30–70 years old)- subjects with BPPV (N = 18) and gender and age-matched healthy controls (N = 18), at rest and during vestibular stimulation. RESULTS: No significant differences were found between groups in HRV parameters during rest. Both groups demonstrated an autonomic response to vestibular stimulation, yet no differences were found between groups. CONCLUSIONS: Patients with BPPV seem to have an intact cardiac response to vestibular stimulation. Over-activation of the Vestibular Semicircular Canals, as shown in BPPV, doesn’t seem to alter the VSR in the cardiac autonomic control system.

BACKGROUND: The lesions besides lateral ventricle and motor recovery following rehabilitation have hardly been studied. OBJECTIVE: To explore the relationship between the size, location of infarction beside the lateral ventricle and motor recovery following rehabilitation. METHODS: A prospective cohort of 55 patients submitted to a Rehabilitation Medical Center between January 2015 and June 2019 who suffered a single cerebral infarction beside the lateral ventricle were included in the study. The size and distance between the posterior margin and the frontal-middle line (FML) of the lesion were measured. Follow-up was conducted until the recovery was no longer progressing. Barthel index and Brunstrom stages were used to evaluate the outcome (full recovery, partial recovery and poor recovery). Variance analysis and nonparametric test were used for the comparison between groups. Multivariate logistic regression analysis was used to screen the factors affecting the outcomes. The Pearson correlation coefficient was used to compare the volume of infarction, behind the FML and the outcomes. RESULTS: Among the 55 patients, the outcome was full recovery (n = 28), partial recovery (n = 13) and poor recovery (n = 14). Multivariate logistic regression analysis showed that volume and location of the infarction were significantly correlated with the outcome (p = 0.039, 0.050). The lesion volume in the full recovery patients was significantly smaller than that in the poor recovery patients (p < 0.01). The posterior edge of the lesion in the full recovery patients behind the FML was statistically significant compared with that in the poor recovery patients (p < 0.01). Spearman correlation analysis showed that the motor recovery was negative correlation to lesion volume (r = –0.508, P < 0.01) and location (r = –0.450, P < 0.01) of the infarction. CONCLUSION: The motor recovery of patients with cerebral infarction beside lateral ventricle is related to the volume and location of the lesion. The larger the volume of the lesion, and the farther the posterior margin of the lesion to the FML, the worse the motor recovery.

Background: Agnosia for objects is often overlooked in neuropsychology, especially with respect to rehabilitation. Prosopagnosia has been studied more extensively, yet there have been few attempts at training it. The lack of training protocols may partially be accounted for by their relatively low incidence and specificity to sensory modality. However, finding effective rehabilitations for such deficits may help to reduce their impact on the social and psychological functioning of individuals. Objective: Our aim in this study was to provide clinicians and researchers with useful information with which to conduct new studies on the rehabilitation of object agnosia and prosopagnosia. To accomplish this, we performed a systematic and comprehensive review of the effect of neuropsychological rehabilitation on visual object and prosopagnosia. Methods: The Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines were followed. In addition, the Single-Case Experimental Design (SCED) and the Critical Appraisal Skills Programme (CASP) scales were used to assess the quality of reporting. Results: Seven articles regarding object agnosia, eight articles describing treatments for prosopagnosia, and two articles describing treatments for both deficits were included. Conclusions: In the light of the studies reviewed, treatments based on analysis of parts seem effective for object agnosia, while prosopagnosia appears to benefit most from treatments relying on holistic/configural processing. However, more attempts at rehabilitation of face and object agnosia are needed to clarify the mechanisms of these processes and possible rehabilitations. Moreover, a publication bias could mask a broader attempt to find effective treatments for visual agnosia and leaving out studies that are potentially more informative.

BACKGROUND: Adopting awkward postures at work has a great impact on productivity and work-related musculoskeletal disorders. Considering anthropometric data in the design of products and workplaces can diminish this impact. The traditional univariate-percentile-approach is one of the most implemented in the anthropometric analysis, even though it has proved limitations in comparison with multivariate-approaches. OBJECTIVE: To develop univariate and multivariate hand models considering four anthropometric dimensions, and to theoretically compare the univariate and multivariate accommodation percentages. METHODS: Univariate percentile models corresponding to the database of real subject nearest-neighbors to the 5th and 95th percentiles were obtained for the male and female population. Two multivariate approaches were implemented on the central 90% of both populations: 2D principal component analysis and archetypal analysis. The accommodation percentage for each family of models was obtained based on the population that simultaneously fit all the anthropometric dimensions. The goodness-of-fit and McNemar’s tests were performed to statistically analyze the accommodation percentages. RESULTS: Eight human hand models were obtained via Principal Component Analysis while two, three, four, and eight Archetypal Analysis models (male-population) and two, three, six, and eight Archetypal Analysis models (female-population) were selected after a root-sum-of-squares analysis for k = 1, ...  ,10 archetypes. CONCLUSION: The results showed that the Principal Component Analysis models obtained a higher accommodation level, followed by the Archetypal Analysis and percentile models (male population). In the case of the female population, models obtained by multivariate-Archetypal Analysis (k = 8) obtained a higher accommodation percentage.

This review provides detailed information on the synthesis, structure, properties, methods for studying, and areas of application conductive polymers synthesized on the basis of phenylenediamines. Conductive polymers based on phenylenediamines are cationic salts of highly conjugated polymers and are synthesized by electrochemical or chemical oxidation. Chemical oxidative polymerization has led to the formation of various functional polymers. Depending on the reaction conditions, polyphenylenediamines are produced as powders, colloidal dispersions, thin films, or composites. The close similarity of the chemical structure of polyanilines and polyphenylenediamines endows both groups with some similar properties, such as, for example, redox activity. They act as reductants of noble-metal compounds to the corresponding metals. Due to electrical conductivity and redox activity, as well as the dependence of electrical conductivity on the degree of protonation, it is possible to create various sensors based on polyphenylenediamines. In addition, polyphenylenediamines can be used as one of the components of composite materials, for example, in anticorrosion coatings. In general, some main groups of applications for polyphenylenediamines can be distinguished. The literature indicates a number of areas of their application; they include the corrosion protection of metals, catalysis, electrorheology, sensors, energy-conversion devices, electrochromism, noble-metal recovery, and water treatment. At the same time, polymers of phenylenediamines can be used in medicine, unlike aniline and its oligomers, which have potential toxicity
