Authors: Andrade Jean Jacques da Silva , Cabral Lioney Nobre , Malaspina Odirlei Arruda
Published: October 2017

O freio labial superior quando hipertrófico pode dificultar a higienização, restringir os movimentos de lábio, possibilitar acúmulo de placa bacteriana e prejudicar a fonética. Pode também gerar insatisfação estética para o paciente, além de poder causar diastema em interproxiamal dos incisivos. Este trabalho visa apresentar um caso clínico com um paciente de 17 anos de idade, com o freio labial superior hipertrófico associado a um diastema em interproximal dos incisivos. Houve indicação para remoção cirúrgica do freio labial antes do tratamento restaurador. A técnica de frenectomia escolhida foi a excisional simples. A intervenção cirúrgica foi necessária na remoção do freio labial hipertrófico, para a adequação do meio bucal, criando condições favoráveis ao fechamento do espaço entre os incisivos. Após a remoção do freio o paciente retornou para remoção de sutura e apresentou boa recuperação. Sendo assim também indicado para iniciar o tratamento restaurador estético para o fechamento do diastema.Descritores: Freio Labial; Cirurgia Bucal; Diastema.
Soft Skills in an Online Class
Authors: Moore Kimberly A. , Pearson Brian J.
Published: October 2017

The development of course content and assignments focused on basic horticultural knowledge and theory (hard skills) in an online setting is relatively straightforward and uncomplicated. However, it is slightly more challenging to improve a student’s soft skills like communication, problem solving, critical observation, and professionalism in an asynchronous online classroom environment. To address this challenge, we developed assignments, such as the challenge question, that focused on having students solve situational horticulture problems. In another assignment, we gave students data from an experiment and asked them to summarize and interpret the data. The recent addition of an online scholars ignite assignment (3-minute thesis competition) has turned each student into the teacher for a brief moment and makes the student an active learner and active listener. The addition of etiquette rules to the syllabus, weekly online tasks, and reminders help to develop professionalism and time management skills in addition to organization skills. It is impossible to cover all soft skills in any class but by offering various assignments and assessments, many soft skills are potentially improved.
Performance of Landscape Roses Grown with Minimal Input in the North-central, Central, and South-central United States

Published: October 2017

Landscape roses (Rosa sp.) are popular flowering shrubs. Consumers are less willing or able to maintain landscape beds than in years past and require plants that are not only attractive, but well-adapted to regional climatic conditions, soil types, and disease and pest pressures. Marketing and distribution of rose cultivars occurs on a national level; therefore, it is difficult for U.S. consumers in the U.S. Department of Agriculture (USDA) Plant Hardiness Zones 3 to 5 to identify well-adapted, cold-hardy cultivars. Identifying suitable cultivars that have strong genetic resistance to pests and disease and that will tolerate temperature extremes without winter protection in the USDA Plant Hardiness Zones 3 to 5 is of tremendous value to consumers and retailers in northern states. Twenty landscape rose cultivars, primarily developed in north-central North America, were evaluated at five locations in the United States (three in the north-central United States, one in the central United States, and one in the south-central United States) using the low-input, multiyear Earth-Kind® methodology. Six roses had ≥75% plant survival at the end of the study and were in the top 50% of performers for overall mean horticultural rating at each of the three north-central U.S. sites: ‘Lena’, ‘Frontenac’, ‘Ole’, ‘Polar Joy’, ‘Sunrise Sunset’, and ‘Sven’. Five of these six roses met the same criteria at the central United States (exception ‘Lena’) and the south-central United States (exception ‘Polar Joy’) sites. Cultivar, rating time, and their interaction were highly significant, and block effects were not significant for horticultural rating for all single-site analyses of variance. Significant positive correlations were found between sites for flower number, flower diameter, and overall horticultural rating. Significant negative correlations were found between flower number and diameter within each site and also between black spot (Diplocarpon rosae) lesion size from a previous study and overall horticultural rating for three of the five sites. Cane survival ratings were not significantly correlated with overall horticultural rating, suggesting some cultivars can experience severe winter cane dieback, yet recover and perform well. Data from this study benefit multiple stakeholders, including nurseries, landscapers, and consumers, with evidence-based regional cultivar recommendations and breeders desiring to identify regionally adapted parents.
Studying the Market Potential for Specialty Cultivars of Sunflower Cut Flowers
Authors: Short Kathryne , Etheredge Coleman L. , Waliczek Tina M.
Published: October 2017

In the United States, there is an increasing demand for field- or greenhouse-grown, specialty, locally grown cut flowers. However, certain cultivars of cut flowers are not readily available in the market. The purpose of this research was to produce a crop of novelty sunflowers (Helianthus annuus ‘Firecracker’) and study the marketability of the cut flowers to wholesale and retail florists and consumers. The plants were grown in greenhouses. Stems were harvested and shown to local floral wholesalers/retailers who were individually interviewed on their perceptions of the cut flower as a product. Farmers’ market patrons were administered a quantitative survey to determine their perspectives on locally sourced products and willingness to pay (WTP) for the specialty cut flower (SCF). Results indicated half of the local florists interviewed responded positively to locally grown floral products in general, with all florists willing to pay at the least the same amount for the SCF as they are currently paying for their standard commercially grown, imported cut sunflowers. Farmers’ market customers expressed a WTP of $1.34/stem and/or $10.13/bunch of 10 stems for the SCF with participants who expressed a higher concern for sourcing local products often more willing to pay a higher price for the SCF. Furthermore, among demographic comparisons, there were no differences in WTP based on age, income, and education. However, females were more likely to purchase the SCF when compared with males, and African-Americans were less likely to buy the SCF and willing to pay less for 10-stem bunches when compared with respondents of other ethnic backgrounds. Although many buyers responded positively to the product, results indicate women and those who prefer to buy local would be a good target demographic market for the product.
Plant Growth and Leachate Electrical Conductivity and pH as Influenced by Controlled-release Fertilizer Blends and Coating Technologies
Authors: Grable Carey , Knight Joshua , Ingram Dewayne L.
Published: October 2017

Although controlled-release fertilizers (CRFs) have been used in container-grown ornamental plants for decades, new coating technologies and blends of fertilizers coated for specific release rates are being employed to customize fertility for specific environments and crops. A study was conducted in the transitional climate of Kentucky to determine the nutrient release rates of three controlled-release blends of 8- to 9-month release and growth response of ‘Double Play Pink’ japanese spirea (Spiraea japonica) and ‘Smaragd’ arbovitae (Thuja occidentalis). Fertilizer 1 (16N–3.5P–8.3K–1.8Mg + trace elements) and Fertilizer 2 (18N–3.1P–8.3K–1.8Mg + trace elements) were prototype blends with different experimental polymer coatings. Fertilizer 3 was a blend of 18N–2.2P–6.6K–1.1Ca–1.4Mg–5.8S + trace elements, which combined 100% resin-coated prills with a polymer coating. Fertilizer 4 was commercially available 15N–3.9P–10K–1.3Mg–6S + trace elements. Fertilizer 3 released its nutrients earlier in the 12-week study than the other three fertilizers and resulted in lower shoot dry weight in both species. The new polymer coating technologies show promise for delivering a predicted release rate and are appropriate for container production of these woody shrubs in Kentucky. An interesting side note of this experiment was that leachate pH measurements across treatments averaged 1.2 units lower for arbovitae (6.3) than for japanese spirea (7.5) at week 12. It was assumed that chemical and/or biological reactions at the root/substrate interface in arbovitae moderated pH increases over the study.
Lettuce Grow: Universities Collaborating with Nonprofits to Provide Child Care Development Educators with Garden Knowledge and Experience
Authors: Fontenot Kathryn , Bush Edward , Gravois Rebecca
Published: October 2017

University-based horticulture departments and extension agents have explored the relationship between gardening programs and consumer knowledge and preferences. Studies have established positive correlations between garden participation and increased science scores and heightened environmental stewardship. The objective of this research was to determine if participation in “Lettuce Grow” garden workshops cohosted by the Louisiana State University Agriculture Center (LSU AgCenter) and Volunteers of America Greater Baton Rouge (VOA-GBR) had positive effects on child care providers’ garden knowledge and willingness to implement garden programming with children aged 5 years and younger. Participation led to a 67% increase (P ≤ 0.05) in horticulture knowledge for participants and resulted in 76.2% of the child care providers actively engaged in growing a garden with youth aged 5 years and under. Based on this experience, we highly recommend universities partner with local nonprofits to engage in deeper meaning, science-based garden extension projects.

Authors: García-Caparrós Pedro , Llanderal Alfonso , El-Tarawy Ahmed , Majsztrik John , Lao María Teresa
Published: October 2017

This experiment measured plant growth of a halophyte (species adapted to saline conditions) confetti tree (Maytenus senegalensis) using runoff from kneeholy plants (Ruscus aculeatus). Three irrigation treatments were used, a standard nutrient solution or control (T0), runoff water collected from kneeholy plants irrigated with the standard nutrient solution blended 50:50 with tap water (T1), and 100% runoff water collected from kneeholy plants irrigated with the standard nutrient solution (T2), in which the nutrient concentrations were analyzed by high-performance liquid chromatography. Growth, photosynthetic parameters, and mineral composition were measured at the end of the experiment. Electrical conductivity and pH increased with increasing runoff application (decreased blending). Treatment 2 had significantly higher plant height, number of branches, number of leaves, leaf area index, and dry weight. Treatments 1 and 2 had significantly lower root lengths compared with the control. Chlorophyll concentration and green index color in leaves were greater in T2 and T1 than T0. The mineral composition of roots and leaves was affected by irrigation treatment, resulting in an increase of sodium and chloride concentration and a decline of nitrogen and phosphorous concentration compared with the control. The reuse of runoff water was beneficial for growing this commercially important halophytic species in Spain, a consideration that is particularly relevant in locations with water quality, quantity issues, or both.
Assessing the Economic Contributions and Benefits of Consumer Horticulture

Published: October 2017

Consumer horticulture (CH) programming can result in outcomes and impacts at the individual level, such as money saved by reducing inputs, greater return on the landscape investment, healthier plants, and improved quality of life. It may also lead to community-level impacts that provide public value, such as water quality protection, water conservation, and protection of biodiversity. In addition to documenting such outcomes and impacts, it is important to quantify their economic value, connect the value to actions taken by extension audiences, and demonstrate to extension’s stakeholders a return on investment. However, it is difficult to document the economic contributions of consumer horticulture and even more difficult to document the economic impact of consumer horticulture extension programs. CH reaches individuals and communities directly and indirectly through personal gardens and landscapes, indoor flowers and plants, school and community gardens, and horticulture therapy. The economic contributions and benefits of consumer horticulture are challenging to quantify, but can be evaluated using several different strategies, including measuring the consumer dollars spent and the economy driven by consumers’ purchase of gardening supplies and landscape services. A second strategy is to examine the value of consumers’ gardening actions on environmental ecosystem services that support soils and plants, provide food and raw materials, and regulate functions, such as pollination, storm water catchment, water quality preservation, green waste reduction, and wildlife habitat and diversity. A third strategy is to focus on cultural, social, and health system services, such as education, recreation, and therapy, that result in exercise, nutrition, health, and happiness. Using a combination of these strategies, workgroups of Tennessee extension professionals are balancing the feasibility of data collection with the usefulness of the data gathered by developing realistic and robust outcome indicators that will form the basis for local and statewide reporting.

Published: October 2017

Completely enclosed screen houses can physically exclude contact between the asian citrus psyllid [ACP (Diaphorina citri)] and young, healthy citrus (Citrus sp.) trees and prevent huanglongbing (HLB) disease development. The current study investigated the use of antipsyllid screen houses on plant growth and physiological parameters of young ‘Ray Ruby’ grapefruit (Citrus ×paradisi) trees. We tested two coverings [enclosed screen house and open-air (control)] and two planting systems (in-ground and container-grown), with four replications arranged in a split-plot experimental design. Trees grown inside screen houses developed larger canopy surface area, canopy surface area water use efficiency (CWUE), leaf area index (LAI) and LAI water use efficiency (LAIWUE) relative to trees grown in open-air plots (P < 0.01). Leaf water transpiration increased and leaf vapor pressure deficit (VPD) decreased in trees grown inside screen houses compared with trees grown in the open-air plots. CWUE was negatively related to leaf VPD (P < 0.01). Monthly leaf nitrogen concentration was consistently greater in container-grown trees in the open-air compared with trees grown in-ground and inside the screen houses. However, trees grown in-ground and inside the screen houses did not experience any severe leaf N deficiencies and were the largest trees, presenting the highest canopy surface area and LAI at the end of the study. The screen houses described here provided a better growing environment for in-ground grapefruit because the protective structures accelerated young tree growth compared with open-air plantings while protecting trees from HLB infection.
Protected Fresh Grapefruit Cultivation Systems: Antipsyllid Screen Effects on Environmental Variables inside Enclosures

Published: October 2017

Huanglongbing (HLB) disease is a threat to most citrus (Citrus sp.) producing areas and is associated with the bacterium Candidatus Liberibacter asiaticus. The disease is transmitted by the vector asian citrus psyllid [ACP (Diaphoria citri)]. Antipsyllid screen houses can potentially reduce and eliminate HLB development in young citrus plantings by excluding the insect vector. These structures are also anticipated to represent a new environmental platform to cultivate high-valued fresh citrus. The purpose of this investigation was to evaluate the effect of screen houses on excluding infective ACP from inoculating grapefruit (Citrus ×paradisi) trees and determine changes on environmental conditions caused by the screen cloth. We tested two coverings [enclosed screen house and open-air (control)] and two planting systems (in-ground and container-grown), with four replications arranged in a split-plot experimental design. Psyllid counting and HLB diagnosis were performed monthly, and the antipsyllid screen excluded the HLB vector from the houses. ACP and HLB-positive trees were found only at the open-air plots. Weather monitoring was performed every 30 minutes from 22 Feb. to 31 July 2014. Solar radiation accumulation averaged 6.7 W·m−2·minute−1 inside the screen houses and 8.6 W·m−2·minute−1 in the open-air. Air temperature was greater inside the screen houses whereas wind gusts were higher in the open-air. Reference evapotranspiration accumulation averaged 3.2 mm·day−1 inside the screen houses and 4.2 mm·day−1 in the open-air. There was no difference in cumulative rainfall between screen houses and open-air. The antipsyllid screen houses reduced solar radiation, maximum wind gust, and reference evapotranspiration (ETo). The environmental conditions inside the protective screen houses are suitable for grapefruit production.
Reliability of Soil Sampling Method to Assess Visible Biodegradable Mulch Fragments Remaining in the Field after Soil Incorporation

Published: October 2017

Biodegradable mulches (BDMs) provide a unique advantage to growers in that they can be tilled into the soil after use, eliminating disposal costs that include time, labor, and equipment needs. Biodegradation of BDMs in the soil can be assessed by the presence of visible mulch fragments; although this is not a direct measure of biodegradation, it provides an initial estimation of mulch biodegradation. We carried out three field experiments to develop a protocol for quantifying BDM fragments in the soil after soil incorporation of mulch. Expt. 1 was done at Mount Vernon, WA, and Knoxville, TN, using five BDMs in four replications, including a polyethylene (PE) mulch reference treatment (three replications and at Mount Vernon only), and a ʽCinnamon Girl’ pumpkin (Cucurbita pepo) test crop. At the end of the growing season, mulches were tilled into the soil to a depth of 6 inches and within 16 days, five soil samples were collected with a golf hole cutter (4 inches diameter and 6 inches deep). Fifty-nine percent of the PE mulch fragments were recovered from the reference treatment. Among the remaining treatments, there was a high plot-to-plot variation as to the percent of the BDM recovered (3% to 95% at Mount Vernon, 2% to 88% at Knoxville). To exclude the possibility of mulch degradation impacting mulch recovery, in Expts. 2 and 3 (at Mount Vernon only), one BDM was laid, then tilled into the soil and sampled using the same sampling core as in Expt. 1, but all in 1 day. In Expt. 2, 15 soil samples were collected per plot, which recovered 70% of the mulch, and in Expt. 3, the entire plot was sampled by collecting 128 soil samples per plot, which recovered 62% of the mulch. In summary, sampling with a relatively large core recovered less than 70% of tilled-in mulch, there was high variability between plots within each treatment because of uneven distribution of the mulch fragments in the plot, and even 50 samples per plot did not provide an accurate estimate of the amount of mulch remaining in the field. Thus, soil sampling with a large core was ineffective, and new sampling methods are needed to assess the amount of BDM remaining in the field after soil incorporation.

Published: October 2017

The creation and educational impact of a reciprocal travel exchange program for student groups in horticulture and allied sciences between Iowa State University (ISU) and the University of Costa Rica (UCR) are described. The program, called the “Intercambio,” (“exchange,” in English), has facilitated group travel for 10- to 12-day periods to farms and agricultural research centers in the host country annually since 1999. The article explores how the Intercambio began and factors that have helped to sustain it, to provide ideas for educators interested in initiating similar exchanges. Analysis of responses to a 2015 written survey of student participants indicated that the Intercambio has exerted a strong impact on academic studies and career choices for 77% of the ISU students and 100% of the UCR students, as well as amplifying interest in the other country and raising cultural understanding and tolerance.

Las técnicas de la “gestión social” de poblaciones impactadas por proyectos hidroeléctricos como instrumento de gobierno
Authors: Muñoz Gaviria Gustavo
Published: October 2017

El presente artículo analiza las técnicas y prácticas de la “gestión social” en la construcción de proyectos hidroeléctricos, como elementos de un dispositivo de gobierno para fijar las condiciones favorables a la expansión del sector. Este es un tipo de dispositivo compuesto por formas de visibilidad, enunciación, poder y subjetividad. La información empírica fue recopilada en 2014 mediante trabajo etnográfico con las poblaciones impactadas por el proyecto Hidroeléctrico Porce III, construido en Antioquia-Colombia en la década de 2000. Este abordaje permitió la desnaturalización de esas técnicas y prácticas, para situarlas en una lógica más amplia de expansión del capital, donde la autogestión de los afectados juega un papel central.

Novice programmerâ€™s misconception of programming reflected on problem-solving plans
Authors: Kwon Kyungbin
Published: October 2017

Understanding the misconception of students is critical in that it identifies the reasons of errors students make and allows instructors to design instructions accordingly. This study investigated the mental models of programming concepts held by pre-service teachers who were novice in programming. In an introductory programming course, students were asked to solve problems that could be solved by utilizing conditional statements. They developed solution plans pseudo-code including a simplified natural language, symbols, diagrams, and so on. Sixteen solution plans of three different types of problems were analyzed. As a result, the studentsâ€™ egocentric and insufficient programming concepts were identified in terms of the misuse of variables, redundancy of codes, and weak strategic knowledge. The results revealed that the students had difficulty designing solution plans that could be executed by computers. They needed instructional supports to master how to express their solution plans in the way computers run. Problem driven instructional designs for novice students were discussed.
Cascade-based multi-scale AI approach for modeling rainfall-runoff process
Authors: Nourani Vahid , Andalib Gholamreza , Sadikoglu Fahreddin , Sharghi Elnaz
Published: October 2017

In this paper, runoff time series of the sub-basins in a cascade form were decomposed by Wavelet Transform (WT) to extract their dynamical and multi-scale features for modeling Multi-Station (MS) rainfall-runoff (R-R) process of the Little River Watershed (LRW) in USA. A Self-Organizing Map (SOM) clustering technique was also employed to find homogeneous extracted sub-series' clusters. As a complementary feature, extraction criterion of mutual information (MI) was utilized for proper cluster agent choice to impose to the artificial intelligence (AI) models (Feed Forward Neural Network, FFNN; Extreme Learning Machine, ELM; and Least Square Support Vector Machine, LSSVM) to predict the runoff of the LRW sub-basins. The performance of wavelet-based runoff prediction was compared to the Markovian-based MS model. The proposed method not only considers the prediction of the outlet runoff but also covers predictions of interior sub-basins behavior. The outcomes showed that the proposed AI-models combined with the SOM and MI tools enhanced the MS runoff prediction efficiency up to 23% in comparison with the Markovian-based models. Nevertheless, benefit of the seasonality of the process along with reduction of dimension of the inputs could help the AI-models to consume pure information of the recorded data.
Remediation of arsenic(III) from aqueous solutions using zero-valent iron (ZVI) combined with potassium permanganate and ferrous ions

Published: October 2017

A system of zerovalent iron combined with potassium permanganate and ferrous irons (Fe(II)-KMnO4-ZVI) was used to remove As(III), one of the most poisonous wastewater pollutants. The Fe(II)-KMnO4-ZVI system was characterized by using X-ray photoelectron spectroscopy and scanning electron microscopy. The As(III) removal efficiency by the Fe(II)-KMnO4-ZVI system under different conditions was investigated and the experimental data were fitted to adsorption kinetics and isotherm models. As(III) could be removed by both physisorption and chemisorption through mixing adsorbents in a very short time (minute scale) with high removal ratios (more than 99.5%) over a wide range of pH (1–9) and concentration (20–100 mg/L). The removal of As(III) by the Fe(II)-KMnO4-ZVI system agreed well with pseudo-first-order reaction kinetics and pseudo-second-order reaction kinetics. The Freundlich isotherm provided a good model of the adsorption system, indicating that the Fe(II)-KMnO4-ZVI system has heterogeneous structure. The results show that the Fe(II)-KMnO4-ZVI system exhibited a high removal efficiency for As(III), which suggested that it might be an effective material for As(III) remediation.
Preparation and characterization of polysulfone/zeolite mixed matrix membranes for removal of low-concentration ammonia from aquaculture wastewater
Authors: Moradihamedani Pourya , Abdullah Abdul Halim
Published: October 2017

Removal of low-concentration ammonia (1–10 ppm) from aquaculture wastewater was investigated via polysulfone (PSf)/zeolite mixed matrix membrane. PSf/zeolite mixed matrix membranes with different weight ratios (90/10, 80/20, 70/30 and 60/40 wt.%) were prepared and characterized. Results indicate that PSf/zeolite (80/20) was the most efficient membrane for removal of low-concentration ammonia. The ammonia elimination by PSf/zeolite (80/20) from aqueous solution for 10, 7, 5, 3 and 1 ppm of ammonia was 100%, 99%, 98.8%, 96% and 95% respectively. The recorded results revealed that pure water flux declined in higher loading of zeolite in the membrane matrix due to surface pore blockage caused by zeolite particles. On the other hand, ammonia elimination from water was decreased in higher contents of zeolite because of formation of cavities and macrovoids in the membrane substructure.

BACKGROUND

Naturalistic driving studies, designed to objectively assess driving behavior and outcomes, are conducted by equipping vehicles with dedicated instrumentation (eg, accelerometers, gyroscopes, Global Positioning System, and cameras) that provide continuous recording of acceleration, location, videos, and still images for eventual retrieval and analyses. However, this research is limited by several factors: the cost of equipment installation; management and storage of the large amounts of data collected; and data reduction, coding, and analyses. Modern smartphone technology includes accelerometers built into phones, and the vast, global proliferation of smartphones could provide a possible low-cost alternative for assessing kinematic risky driving.

OBJECTIVE

We evaluated an in-house developed iPhone app (gForce) for detecting elevated g-force events by comparing the iPhone linear acceleration measurements with corresponding acceleration measurements obtained with both a custom Android app and the in-vehicle miniDAS data acquisition system (DAS; Virginia Tech Transportation Institute).

METHODS

The iPhone and Android devices were dashboard-mounted in a vehicle equipped with the DAS instrumentation. The experimental protocol consisted of driving maneuvers on a test track, such as cornering, braking, and turning that were performed at different acceleration levels (ie, mild, moderate, or hard). The iPhone gForce app recorded linear acceleration (ie, gravity-corrected). The Android app recorded gravity-corrected and uncorrected acceleration measurements, and the DAS device recorded gravity-uncorrected acceleration measurements. Lateral and longitudinal acceleration measures were compared.

RESULTS

The correlation coefficients between the iPhone and DAS acceleration measurements were slightly lower compared to the correlation coefficients between the Android and DAS, possibly due to the gravity correction on the iPhone. Averaging the correlation coefficients for all maneuvers, the longitudinal and lateral acceleration measurements between iPhone and DAS were rlng=0.71 and rlat=0.83, respectively, while the corresponding acceleration measurements between Android and DAS were rlng=0.95 and rlat=0.97. The correlation coefficients between lateral accelerations on all three devices were higher than with the corresponding longitudinal accelerations for most maneuvers.

CONCLUSIONS

The gForce iPhone app reliably assessed elevated g-force events compared to the DAS. Collectively, the gForce app and iPhone platform have the potential to serve as feature-rich, inexpensive, scalable, and open-source tool for assessment of kinematic risky driving events, with potential for research and feedback forms of intervention.
Терапевтичний потенціал бактеріофагів та ендолізинів при лікуванні гострих респіраторних інфекцій, викликаних бактеріальними патогенами
Authors: Abaturov А.Е. , Kryuchko Т.А.

Бактеріофаги являють собою віруси, які за рахунок рецептор/ліганд-взаємодії здатні специфічно зв’язуватися з бактеріальною стінкою і відновлюватися всередині певних мікроорганізмів. Літичні ферменти бактеріофагів ефективно руйнують клітинну стінку бактерій, але на відміну від антибіотиків не впливають на життєдіяльність симбіотичної флори. На сьогодні існує велика кількість наукових матеріалів, що стосуються ефективності антистрептококових, антистафілококових, антиклебсієльозних, антисинегнійних бактеріофагів і ендолізинiв, які здатні викликати загибель антибіотикорезистентних бактерій, у зв’язку з чим їх використовують як бактерицидні лікарські засоби, що є потенційно ефективним терапевтичним методом протимікробної терапії. Високий рівень ефективності бактерицидної дії ендолізинів дозволяє висловити припущення, що майбутні лікарські засоби, створені на молекулярній основі ендолізинів, можуть стати ключовими протимікробними препаратами при лікуванні інфекційних захворювань.
Сучасні аспекти діагностики, лікування та профілактики ожиріння в дітей
Authors: Saltanova S.D.
Published: October 2017

Ожиріння є однією з актуальних медико-соціальних проблем сучасності. Відзначається збільшення поширеності ожиріння серед дітей. Кількість дітей у світі віком до 5 років із надлишковою масою тіла та ожирінням становить 44 мільйони. Ожиріння в дитячому віці є фактором ризику для розвитку тяжкої супутньої патології. Дитяче ожиріння — тяжкий прогностичний фактор ожиріння в дорослих. Реєструється підвищений рівень передчасної смерті в дорослих, які страждали від ожиріння в дитинстві. Заходи профілактики та лікування дитячого ожиріння повинні бути спрямовані на всю родину, а не тільки на хвору дитину. З метою профілактики ожиріння слід обмежувати надлишкове вживання калорій. Для підвищення ефективності профілактики ожиріння в дітей вживання енергії потрібно поєднувати з підвищенням фізичної активності. Основним методом лікування ожиріння в дітей є модифікація способу життя, що включає корекцію харчування, призначення фізичних навантажень та поведінкову терапію. Впровадження шкільних програм, що передбачають збільшення фізичної активності та оптимізацію харчування школярів, підвищує ефективність боротьби з дитячим ожирінням. Фармакотерапія при ожирінні в дітей призначається при неефективності програм з модифікації способу життя. Для медикаментозного лікування ожиріння в дітей застосовується орлістат. Ефективність фармакотерапії підвищується при її поєднанні з комплексними програмами з модифікації способу життя. За кордоном при морбідному ожирінні в підлітків у разі неефективності нехірургічного лікування використовується баріатрична хірургія. У результаті оперативного втручання знижується індекс маси тіла, покращується перебіг супутніх захворювань, підвищується якість життя пацієнтів. Баріатрична хірургія пов’язана з ризиком розвитку побічних ефектів, що потребує проведення безперервного моніторингу ускладнень. Для лікування та профілактики ожиріння в дітей необхідним є мультидисциплінарний підхід із залученням спеціалістів різного профілю.

Провокуючі фактори дебюту моторних симптомів хвороби Паркінсона
Authors: Boiko A.V.
Published: October 2017

Актуальність. Хвороба Паркінсона (ХП) — одне з найбільш частих нейродегенеративних захворювань. Незважаючи на 200-річчя його наукового вивчення, етіологія ХП залишається до кінця невідомою. Раніше встановлено, що латентна і премоторна фаза на 4–10 років передують розвитку класичних проявів ХП. Залишається відкритим питання виділення провокуючого фактора клінічної маніфестації моторних симптомів ХП. Мета дослідження: визначити найбільш часті провокуючі фактори розвитку моторних симптомів ХП шляхом проведення анкетного опитування пацієнтів. Матеріали та методи. Опитано 120 пацієнтів з ХП. Анкета розроблена автором для виявлення факторів, що провокують маніфестацію ХП. Отримані клінічні дані й результати анкетування піддали статистичній обробці. Рівень значущості р приймали рівним 0,05. Результати. 53,33 % (64 пацієнта) зв’язали розвиток моторних симптомів ХП із перенесеною значущою гострою психотравмуючою ситуацією. Часовий інтервал між дією стресового чинника і дебютом захворювання варіював від 1 дня до 4 років (медіана (Me) 5,2 місяця; 95% ДІ 2,1–9,1 місяця). Перенесені гострі респіраторні інфекції в дебюті розвитку або за 2–4 місяці до розвитку ХП відзначили 3,33 % (4 людини). Больові синдроми різної локалізації були виявлені у 8,33 % (10 осіб). Відсутність будь-якого провокуючого фактора відзначили 35 % (42 опитаних). Обробка клінічних даних (стать, вік дебюту ХП і склад за клінічними формами ХП) не виявила статистично значущих відмінностей між групами з різними провокуючими факторами дебюту ХП. Висновки. Розвиток моторних симптомів ХП у багатьох пацієнтів може бути спровоковано низкою факторів, серед яких переважав дистрес. Сформульована автором гіпотеза формування зони абсолютної рефрактерності в дофамінергічній системі після стресового впливу в дебюті моторних симптомів ХП потребує експериментального підтвердження.

Published: October 2017

У статті надано аналіз світової епідеміологічної статистики з проблеми черепно-мозкової травми (ЧМТ). Згідно з літературними даними, показники поширеності ЧМТ в світі становлять від 83 до 580 на 100 тис. населення на рік; показники смертності населення від ЧМТ — від 6,3 до 40,8 на 100 тис. населення на рік, причому ці показники залежать від якості статистичної вибірки. Проведено аналіз епідеміологічних показників, що характеризують ЧМТ в Республіці Білорусь, і дана оцінка їх динаміці за останні 5 років. Поширеність ЧМТ знизилася з 247,3 в 2011 р. до 201,4 в 2013 р., потім підвищилася до 239,6 в 2015 р. Смертність населення мала стійку тенденцію до зниження з 20,2 в 2011 р. до 10,4 в 2015 р. При цьому відзначено зниження догоспитальної летальності з 69,5 % у 2011 р. до 37,7 % у 2015 р. Загальнодержавні й галузеві (охорона здоров’я) заходи щодо поліпшення якості надання медичної допомоги пацієнтам з ЧМТ забезпечили суттєве покращення результатів: зниження смертності населення від ЧМТ на 48,5 %, зниження летальності при ЧМТ серед постраждалих на 47,6 %. Було доведено, що включення в комплексну терапію препаратів цитиколін, гемодеріват і L-лізину есцинат значно покращує виживаність пацієнтів із тяжкою ЧМТ.
Алгоритм ранньої діагностики гетеротопічної осифікації у хворих із травмою хребта та спинного мозку
Authors: Povoroznyuk V.V. , Bystrytska M.A. , Balatska N.I.
Published: October 2017

В статті наведені особливості маркерів ремоделювання кісткової тканини в пацієнтів із травмою хребта та спинного мозку (ТХСМ) і гетеротопічною осифікацією (ГО). ТХСМ призводить як до підвищення маркерів резорбції, так і до формування кісткової тканини з переважанням процесів резорбції. Розвиток ГО характеризується значним підвищенням формування кісткової тканини порівняно з практично здоровими особами та пацієнтами з ТХСМ без ГО. Алгоритм ранньої діагностики ГО у цієї категорії хворих включає виділення групи ризику розвитку ГО, активне визначення клінічних ознак ГО в період найбільш частого початку її розвитку (3 тижні — 6 місяців), визначення концентрації остеокальцину та/або P1NP у сироватці крові. Показники маркера формування кісткової тканини P1NP ≥ 187,3 нг/мл та рівень остеокальцину ≥ 49,6 нг/мл можна розглядати як вірогідний предиктор розвитку ГО в пацієнтів із ТХСМ.
Патогенез транзиторных ишемических атак: проблема подтипов
Authors: Vinychuk S.M. , Fartushna O.Ye.
Published: October 2017

Патофизиология транзиторных ишемических атак (ТИА) определяется многими неблагоприятными факторами. Поэтому выделение ведущих патофизиологических механизмов, которые формируют определенные патогенетические подтипы ТИА и определяют их гетерогенность, остается перспективным направлением клинической ангионеврологии и во многом предопределяет выбор терапевтической стратегии и объем средств дифференцированной неотложной медицинской помощи больным. Целью нашей работы было изучение и обобщение данных научной литературы о патогенезе ТИА и проблеме их подтипов. Был проведен аналитический обзор научных публикаций за последние 15 лет с использованием современных наукометрических баз данных и фондов научных библиотек Украины, ЕС, Великобритании, США. Проведенный анализ свидетельствует, что определение ведущего патогенетического механизма ТИА имеет принципиальное значение для проведения дифференцированных лечебно-профилактических мероприятий и курации таких пациентов. Поэтому для врачей-неврологов приоритетным остается выделение из комплекса патофизиологических механизмов ведущих, которые формируют патогенетический подтип ТИА, определяют характерные клинические проявления и течение ТИА, объем, продолжительность и обратимость неврологического дефицита, то есть особенности восстановления неврологических функций, неврологическое выздоровление при различных подтипах заболевания.
