Authors: Owsianowska Joanna 
Published: August 2017

Wstęp: Hemofilia należy do chorób uwarunkowanych genetycznie. Występowanie krwawień, doznawanie bólu, okresowe lub trwałe zmniejszenie aktywności fizycznej czy wreszcie ryzyko wystąpienia kalectwa mogą wywierać negatywny wpływ nawielowymiarowe funkcjonowanie człowieka.Celem pracy było poznanie poziomu jakości życia chorych na hemofilię oraz udzielenie odpowiedzi na następujące pytania badawcze: 1. Jaki poziom jakości życia prezentują chorzy na hemofilię? 2. Która dziedzina jakości życia oceniana jest przez chorych na hemofilię najwyżej, a która najniżej? 3.Czy istnieje związek pomiędzy danymi socjodemograficznymi i sytuacją zdrowotną a jakością życia i jej dziedzinami?Materiały i metody: Badaniami objęto 168 dorosłych pacjentów chorujących na hemofilię, pozostających głównie w systemie leczenia domowego i zamieszkujących różne regiony Polski. Dane socjodemograficzne zebrano za pomocą ankiety własnego autorstwa, natomiast do pomiaru jakości życia zastosowano zaproponowany przez Światową Organizację Zdrowia kwestionariusz WHOQOL-100 służący do oceny sytuacji życiowej pacjentów będącej konsekwencją choroby i stosowanej terapii.Wyniki: Wszyscy badani chorzy byli płci męskiej i chorowali na hemofilię A, co jest zgodne zarówno z epidemiologią schorzenia, jak i z faktem, iż hemofilia A występuje w Polsce znacznie częściej niż hemofilia B. Najliczniejszą grupę (144 mężczyzn) stanowili pacjenci z ciężką postacią choroby, najmniej liczną ze stopniem lekkim (6 osób), natomiast stopień umiarkowany choroby występował u 18 badanych. Trzy czwarte (126 osób) miało wirusowe zapalenie wątroby typu C. W zakresie 6 dziedzin jakości życia zmierzonych za pomocą kwestionariusza WHOQOL-100 najwyższy wynik 14,66 uzyskano wdziedzinie duchowości, religii i osobistych przekonań, natomiast najniższy w dziedzinie fizycznej 12,99, zwłaszcza w podskali mierzącej ból i dyskomfort oraz dziedzinie środowiskowej 12,89.Wnioski: 1. Badana grupa mężczyzn z wrodzoną hemofilią wykazuje średni poziom jakości życia, porównywalny z jakością życia chorych z innych krajów europejskich. 2. Badana grupa chorych najwyżej ocenia dziedzinę związaną z duchowością, religią i osobistymi przekonaniami, natomiast najniżej dziedzinę fizyczną i środowiskową. 3. Na istotne obniżenie globalnej jakości życia wpływa ciężki stopień choroby, wirusowe zapalenie wątroby typu C oraz status rencisty.

Wstęp: Selen (Se) jest składnikiem enzymów oksydoredukcyjnych i cytochromów. Wpływa również na wzrost i proliferację komórek oraz jest niezbędny doprawidłowego funkcjonowania układu immunologicznego. Celem badań było oznaczenie stężenia selenu w wątrobie, nerkach, płucach, sercu i tkance mięśniowej psa domowego (Canis lupus familiaris) z terenu północno-zachodniej Polski.Materiały i metody: Próbki narządów i tkanek pobrano od 15 psów w wieku od 1 miesiąca do 17 lat. Dieta zwierząt była podobna do diety człowieka, z niewielką ilością komercyjnej karmy. Stężenia selenu były oznaczane metodą spektrofluorymetryczną.Wyniki: Największe średnie stężenie Se u badanych psów stwierdzono w nerkach (0,57 ±0,42 mg/kg mokrej masy – m.m.), a najmniejsze w mięśniach (0,11 ±0,09 mg/kg m.m.). Średnie stężenie Se w badanych narządach i tkankach psów można ułożyć w następujący szereg: nerki>wątroba>płuca>serce>mięśnie.Wnioski: U 75% badanych psów wartości stężenia Se w badanych materiałach znajdowały się poniżej optymalnego poziomu, co świadczy o niedoborze Se. Wyniki sądowodem na to, że dieta psów bardzo podobna do diety ludzkiej nie jest wystarczająca dla optymalnego poziomu Se w organizmach zwierząt.

Published: August 2017

Ropień zagardłowy u osób dorosłych jest schorzeniem występującym rzadko. W niewielkiej liczbie przypadków jest to powikłanie zębopochodnego stanu zapalnego implikowanego przyjmowaniem metotreksatu. Przypadek taki został opisany w niniejszej pracy.W rozpoznaniu ropnia zagardłowego istotną rolę odgrywa diagnostyka obrazowa ze wskazaniem na tomografię komputerową szyi z kontrastem. Po właściwym ustaleniu rozpoznania niezbędne jest szybkie wdrożenie właściwego postępowania terapeutycznego: zachowawczego w postaci antybiotykoterapii o szerokim spektrum, a w uzasadnionych sytuacjach również chirurgicznego. U chorych leczonych chirurgicznie stosuje się przezszyjny dostęp do przestrzeni zagardłowej. W przypadku opisanym w niniejszej pracy zastosowano drenaż przestrzeni zagardłowej za pomocą drenu płuczącego własnej konstrukcji, który umożliwił skuteczne odprowadzenie treści ropnej. Postępowanie to pozwoliło na uniknięcie niebezpiecznego powikłania, jakim jest zstępujące martwicze zapalenie śródpiersia, i umożliwiło całkowite wyleczenie chorego.Słowa kluczowe: dren płuczący; drenaż przestrzeni zagardłowej; ropień zagardłowy; tomografia komputerowa z kontrastem.

Published: August 2017

Leczenie gruźlicy płuc powietrzem i odpowiedni dietą znane było od kilku tysięcy lat. Zagadnienie to rozpatrywane było m.in. przez Aulusa Corneliusa Celsusa (53 r. p.n.e.–7 r. n.e.), Areteusza zKapadocji (I–II. w.), Pliniusza Starszego (24–79) i Galena. Przyjmuje się, że pierwsze sanatorium przeciwgruźlicze zostało założone w Görbersdorfie (Sokołowsko) na Śląsku w 1854 r. przez Hermanna Brehmera (1821–1889), lekarza niemieckiego, który leczył choroby dróg oddechowych. Jednak już wcześniej zajmowano się tym problemem. Angielski lekarz William Buchan (1729–1805) w wydanym w 1769 r. dziele „Domestic medicine or the family physician” zalecał na gruźlicę płuc czyste i świeże powietrze, odżywianie się mlekiem oraz przejażdżki konne. George Bodington (1799–1882), autor „Essay on the treatment and cure of pulmonary consumption on principles natural, rational and successful”, na 14 lat przed Brehmerem przedstawił zasady leczenia sanatoryjnego gruźlicy płuc powietrzem i dietą w Sutton Coldfield w hrabstwie Warwickshire. W 1846 r. John Forbes (1787–1861) i Charles James Blasius Williams (1805–1889) założyli The Hospital for Consumption and Diseases of the Chest w Brompton, duży zakład przeznaczony wyłącznie dla chorych na gruźlicę. Były to osiągnięcia niezwykle istotne dla leczenia sanatoryjnego gruźlicy płuc.

Evaluation of Imazapic Applications for Establishment of Southeastern Wildrye
Authors: Rushing J. Brett , Thornton Matthew T. 
Published: August 2017

Core Ideas
Southeastern wildrye can be successfully established using imazapic as a pre‐ and post‐emergence herbicide.
Lower rates of imazapic are successful at controlling winter annual weeds, such as henbit and little barley, during establishment of southeastern wildrye.
Southeastern wildrye end of season dry matter yields decrease with increasing rates of imazapic.
Southeastern wildrye [Elymus glabriflorus (Vasey ex L.H. Dewey) Scrib & C.R. Ball] is a native, cool‐season, perennial grass that shows promise as a forage crop for the southeastern United States. Little is known about the proper methods of establishment for this species, particularly its ability to tolerate pre‐ and post‐emergence applications of imazapic. Replicated field trials were established in Newton and Starkville, MS, in the fall of 2014 and 2015. Pre‐ and post‐emergence treatments included an untreated control, and application rates of 0.035, 0.07, 0.105, and 0.14 kg ai ha−1, which were applied to conventionally seeded plots. Seedling counts and height data were collected at bi‐weekly intervals, along with visual ratings for weed control. End of season dry matter (DM) yields were also recorded for both establishment years. As expected, higher rates (0.105 and 0.14 kg a.i. ha−1) of imazapic caused significant damage to emerging seedlings in both pre‐ and post‐emergence applications. These rates resulted in greater weed control, but ultimately, in reduced DM yields. Lower pre‐emergence application rates (0.035–0.07 kg a.i. ha−1) resulted in acceptable weed control, and minimal seedling damage. Results from these field trials demonstrates the ability to successfully establish southeastern wildrye with the use of imazapic, thus providing beneficial information for the development of this species as a forage crop for the Southeast.

Published: August 2017

Less than 50% of applied nitrogen (N) fertilizer is typically recovered by corn (Zea mays L.) due to climatic constraints, soil degradation, overapplication, and losses to air and water. Two application methods, two N sources, and two inhibitors were evaluated to reduce N losses and enhance crop uptake. The treatments included broadcast urea (BrUrea), BrUrea with a urease inhibitor (BrUrea+UI), BrUrea with a urease and a nitrification inhibitor (BrUrea+UI+NI), injection of urea ammonium nitrate (InjUAN), and injected with one or both inhibitors (InjUAN+UI, InjUAN+UI+NI), and a control. The BrUrea treatment lost 50% (64.4 kg N ha−1) of the applied N due to ammonia volatilization, but losses were reduced by 64% with BrUrea+UI+NI (23.0 kg N ha−1) and by 60% with InjUAN (26.1 kg N ha−1). Ammonia losses were lower and crop yields were greater in 2014 than 2013 as a result of the more favorable weather when N was applied in 2014. When ammonia volatilization was reduced by adding a urease inhibitor, N2O emissions were increased by 30 to 31% with BrUrea+UI and InjUAN+UI compared with BrUrea and InjUAN, respectively. Pollution swapping was avoided when both inhibitors were used (BrUrea+UI+NI, InjUAN+UI+NI) as both ammonia volatilization and N2O emissions were reduced, and corn grain yields increased by 5% with BrUrea+UI+NI and by 7% with InjUAN+UI+NI compared with BrUrea and InjUAN, respectively. The combination of two N management strategies (InjUAN+UI+NI) increased yields by 19% (12.9 t ha−1) compared with BrUrea (10.8 t ha−1).Core Ideas
Ammonia volatilization resulted in 50% loss of applied urea over 2 yr.
When urease inhibitors were added with urea, ammonia volatilization was reduced by 64%.
Injection of UAN reduced ammonia volatilization by 60% compared with broadcast urea.
N2O emissions were increased by 30 to 31% when urease inhibitors were applied.
Pollution swapping was avoided when both urease and nitrification inhibitors were used.
Correction of Known Position Errors in a Spherical Near to Far-Field Transformation for Long Antennas
Authors: Cicchetti Renato , D’Agostino Francesco , Ferrara Flaminio , Gennarelli Claudio , Guerriero Rocco , Migliozzi Massimo 
Published: August 2017

Background:
This paper provides the experimental validation of an efficient iterative procedure to correct known position errors in a spherical near to far-field (NTFF) transformation for elongated antennas which uses a minimum number of NF measurements.

Method:
This transformation exploits a non-redundant sampling representation of the voltage detected by the probe obtained by shaping a long antenna with a prolate ellipsoid. The uniform samples, those at the points set by the representation, are accurately reconstructed from the acquired not regularly distributed (non-uniform) ones by using an iterative scheme, which requires a one to one relationship between each uniform sampling point and the corresponding non-uniform one. Then a 2-D optimal sampling formula is adopted to evaluate the input data needed to perform the traditional spherical NTFF transformation from the retrieved non-redundant uniform samples.

Conclusion:
Finally, laboratory proofs have been reported to demonstrate the validity of the presented technique from a practical viewpoint.
On the Cellular and Molecular Mechanisms of Drug-Induced Gingival Overgrowth
Authors: Ramírez-Rámiz Albert , Brunet-LLobet Lluís , Lahor-Soler Eduard , Miranda-Rius Jaume 
Published: August 2017

Introduction:Gingival overgrowth has been linked to multiple factors such as adverse drug effects, inflammation, neoplastic processes, and hereditary gingival fibromatosis. Drug-induced gingival overgrowth is a well-established adverse event. In early stages, this gingival enlargement is usually located in the area of the interdental papilla. Histologically, there is an increase in the different components of the extracellular matrix.Objective:The aim of this manuscript is to describe and analyze the different cellular and molecular agents involved in the pathogenesis of Drug-induced gingival overgrowth.Method:A literature search of the MEDLINE/PubMed database was conducted to identify the mechanisms involved in the process of drug-induced gingival overgrowth, with the assistance of a research librarian. We present several causal hypotheses and discuss the advances in the understanding of the mechanisms that trigger this gingival alteration.Results:In vitrostudies have revealed phenotypic cellular changes in keratinocytes and fibroblasts and an increase of the extracellular matrix with collagen and glycosaminoglycans. Drug-induced gingival overgrowth confirms the key role of collagenase and integrins, membrane receptors present in the fibroblasts, due to their involvement in the catabolism of collagen. The three drug categories implicated: calcineuron inhibitors (immunosuppressant drugs), calcium channel blocking agents and anticonvulsant drugs appear to present a multifactorial pathogenesis with a common molecular action: the blockage of the cell membrane in the Ca2+/Na+ ion flow. The alteration of the uptake of cellular folic acid, which depends on the regulated channels of active cationic transport and on passive diffusion, results in a dysfunctional degradation of the connective tissue. Certain intermediate molecules such as cytokines and prostaglandins play a role in this pathological mechanism. The concomitant inflammatory factor encourages the appearance of fibroblasts, which leads to gingival fibrosis. Susceptibility to gingival overgrowth in some fibroblast subpopulations is due to phenotypic variability and genetic polymorphism, as shown by the increase in the synthesis of molecules related to the response of the gingival tissue to inducing drugs. The authors present a diagram depicting various mechanisms involved in the pathogenesis of drug-induced gingival overgrowth.Conclusion:Individual predisposition, tissue inflammation, and molecular changes in response to the inducing drug favor the clinical manifestation of gingival overgrowth.

Published: August 2017

Background:Military and nonmilitary organizations need the capability to support their expeditionary forces by selecting a temporary base of operations that projects a minimal footprint and reduces logistical burdens. For example, strategically sited temporary bases anticipate impacts on the local context and its population of siting and operating temporary bases.Objective:This paper describes a methodology to assess the practicality of incorporating local construction materials when planning for contingency operations in a given region. While the assessment methodology was originally developed for military planners, the principles and methods are applicable to any organization that is considering building and operating temporary locations in foreign nations.Method:The methodology assesses factors such as population densities, main building types, geographical regions, port locations, railroad locations, road networks, airport locations, flood-risk areas, and construction materials. The methodology optimizes all factors to yield the best material-based solution for site selection. To demonstrate the developed methodology, two hypothetical case studies are described–Dhaka in Bangladesh for its high-population density and Maiduguri in Nigeria for its low-population density and potential for disruption.Results:This methodology provides a contingency site selection process that does not currently exist and will assist in the reduction of materiel demand, minimize footprint, and reduce the risk to personnel. The methodology captures factors such as population densities, main building types, geographical regions, port locations, railroad locations, road networks, airport locations, flood-risk areas, and construction materials and optimizes all factors to yield the best material-based solution for site selection.Conclusion:This methodology provides a contingency site selection process that does not currently exist for mission planners. It is designed to produce a methodology with a goal of developing a GIS-based decision support tool to assist in siting bases of operations.
Grandparents’ Perspectives on Parent-Adult Child Relationships During the Transition to Grandparenthood
Authors: Munz Elizabeth A 
Published: August 2017

Objective:
The aim of this study on the transition to grandparenthood is to capture grandparents’ perspectives on their relationship and communication with their adult children when their adult children was expecting their first child or became new parents within the past year. More specifically, the study aimed to uncover 1) Intergenerational issues identified by grandparents during the transition to grandparenthood and 2) Factors influencing grandparents’ communication and relationships with their adult children during this time of family transition.

Method:
Participants were 19 grandparents in the U.S., 15 grandmothers and 4 grandfathers who were about to welcome the first child of one of their children (N = 8), who had welcomed the first child of one of their children in the past year (N = 10), or who had both a child who was expecting and a child who had welcomed their first child within the past year (N = 1). Qualitative data analysis was conducted on transcripts from the grandparent interviews utilizing the constant comparative technique and thematic analysis to identify categories and emergent themes.

Results:
Grandparent participants shared their perspectives on the intergenerational transmission of parenting practices, reflected on changes in parental roles over time, and identified communication facilitator and barriers during this time of transition. These categories and emergent themes are explicated in the results section along with supporting excerpts from grandparent interviews.

Conclusion:
The transition to grandparenthood impacts communication and relationships between grandparents and their adult children by shaping the content, frequency, and medium of communication. Understanding grandparents’ perspectives on this time of transition adds to existing research on families focused mainly on the adult child’s perspective.

Authors: Batacchi Zona , Robinson-Cohen Cassianne , Hoofnagle Andrew N. , Isakova Tamara , Kestenbaum Bryan , Martin Kevin J. , Wolf Myles S. , de Boer Ian H. 
Published: August 2017

Background and objectives
Vitamin D supplements are prescribed to correct low circulating concentrations of 25-hydroxyvitamin D. In CKD, vitamin D metabolism is complicated by decreased conversion of 25-hydroxyvitamin D to 1,25-dihydroxyvitamin D by CYP27B1 and possibly decreased conversion of 25-hydroxyvitamin D to 24,25-dihydroxyvitamin D by CYP24A1. The aim of this study was to determine the effects of vitamin D2 supplementation on vitamin D metabolism in health and CKD.

Design, setting, participants, & measurements
We conducted a treatment-only intervention study of 25 individuals with CKD (eGFR<60 ml/min per 1.73 m2) and 44 individuals without CKD from three academic centers, all with screening 25-hydroxyvitamin D <30 ng/ml. Each participant was prescribed vitamin D2 (ergocalciferol) 50,000 IU orally twice weekly for 5 weeks. We tested whether changes in plasma concentrations of vitamin D metabolites and vitamin D metabolic ratios differed by CKD status. Plasma 1,25-dihydroxyvitamin D3-to-25-hydroxyvitamin D3 ratio and 24,25-dihydroxyvitamin D3-to-25-hydroxyvitamin D3 ratio were calculated as estimates of CYP27B1 and CYP24A1 function, respectively.

Results
With treatment, plasma 25-hydroxyvitamin D2 and total 25-hydroxyvitamin D concentrations increased similarly for participants with and without CKD. For participants without CKD, 1,25-dihydroxyvitamin D2 increased (2.8±1.3–32.9±1.4 pg/ml), whereas 1,25-dihydroxyvitamin D3 decreased (45.6±1.9–14.6±1.9 pg/ml), resulting in no significant change in total 1,25-dihydroxyvitamin D; 1,25-dihydroxyvitamin D3-to-25-hydroxyvitamin D3 ratio decreased (3.0±0.2–1.7±0.2 pg/ng), and 24,25-dihydroxyvitamin D3-to-25-hydroxyvitamin D3 ratio increased (115.7±7.8–195.2±7.9 pg/ng). Individuals with CKD had lower baseline levels and smaller changes in magnitude for 1,25-dihydroxyvitamin D2 (2.1±1.6–24.4±1.6 pg/ml; P interaction =0.01), 1,25-dihydroxyvitamin D3-to-25-hydroxyvitamin D3 ratio (1.8±0.2–1.1±0.2 pg/ng; P interaction =0.05), and 24,25-dihydroxyvitamin D3-to-25-hydroxyvitamin D3 ratio (72.0±9.1–110.3±9.3 pg/ng; P interaction <0.001). Fibroblast growth factor-23 and parathyroid hormone were not significantly changed in either group.

Conclusions
Vitamin D2 supplementation decreases conversion of 25-hydroxyvitamin D3 to 1,25-dihydroxyvitamin D3 and induces vitamin D3 catabolism as evidenced by changes in D3 metabolites and vitamin D metabolic ratios. These effects occur without significant changes in fibroblast growth factor-23 or parathyroid hormone and are blunted in CKD.
