СОВРЕМЕННОЕ СОСТОЯНИЕ И ПЕРСПЕКТИВЫ ЛЕЧЕНИЯ СВИЩА ПОДЖЕЛУДОЧНОЙ ЖЕЛЕЗЫ
Authors: Lupaltsov V. I. 
Published: February 2018

Цель. Оценка современных методов лечения свища поджелудочной железы (СПЖ) с рекомендациями их выбора на современном этапе.
Материалы и методы. Проанализированы результаты лечение 21 больного по поводу СПЖ в возрасте от 28 до 70 лет. СПЖ с полным повреждением протока поджелудочной железы (ПЖ) сформировался у 11 больных, у 4 из них – после выполнения панкреатодуоденальной резекции. Неполное краевое повреждение отмечено у 10 больных, у 5 из них – после деструктивного острого панкреатита (ОП) с исходом в нагноившуюся кисту ПЖ. У 3 больных СПЖ образовался вследствие травмы живота, у 1 – после продольной панкреатоеюностомии по поводу хронического болевого панкреатита, у 1 – деструктивного ОП хвоста ПЖ. Длительность существования СПЖ от 2 мес до 1 года.
Результаты. При выборе метода лечения использована разработанная нами классификация, основанная на анализе поражения протоковой системы ПЖ. Консервативное лечение проведено 8 больным, оперированы – 13, у 9 из них осуществлено внутреннее дренирование, в том числе у 2 – фистулоэнтеростомия по методике Альперовича, у 1 – продольная панкреатоеюностомия, у 1 – левосторонняя панкреатэктомия с иссечением свища. Все пациенты живы.
Выводы.
Улучшение результатов лечения СПЖ и профилактика их образования зависят от проведения патогенетически обоснованной консервативной терапии ОП, совершенствования техники хирургического вмешательства на ПЖ. По поводу наружного СПЖ с полным повреждением протока ПЖ показано оперативное вмешательство с адекватным курсом консервативной терапии. Хирургическое лечение должно быть индивидуальным, в условиях специализированного стационара.

En clínica médica, uno de los motivos de consulta más frecuentes es el dolor torácico, síntoma que responde a una variada causalidad que va desde un dolor muscular o una neuritis intercosatl hasta el infarto agudo de miocardio, la disección aórtica y la tromboembolia pulmonar; estas últimas que enmarcan una gravedad clínica alta y dependiendo de la topografía comprometida, la rapidéz de la instauración del tratamiento y la certeza del diagnóstico clínico conllevan una alta mortalidad. Así mismo, éstas tres entidades, al ser de origen vascular comparten síntomas y signos que en algunos casos complican un diagnóstico certero, requiriendo un trabajo diagnóstico prolijo y aveces con gran necesidad de apoyo diagnóstico analítico y por imagen.
Presentamos el caso de un dolor torácico que evoca con su clínica un infarto agudo del miocardio con sus tres pilares diagnósticos completos (presentación clínica, cambios electrocardiográficos y elevación enzimática); pero que sin embargo de esto, tuvo una evolución que disoció este diagnóstico con la sospecha inicial y nos llevó, gracias a una alta sospecha clínica a diagnosticar un tromboembolismo masivo.

Introduction In peritoneal dialysis (PD) patients, volume overload is related to cardiac dysfunction and mortality, while intravascular volume depletion is associated with a rapid decline in the residual renal function (RRF). This study sought to determine the clinical usefulness of bioimpedance spectroscopy (BIS)-guided fluid management for preserving RRF and cardiac function in PD patients. Subjects and methods This is a multicenter, prospective, open-label study that was conducted over a 1-year period (NCT01887262). Non-anuric (urine volume > 500 mL/day) subjects on PD were enrolled. Subjects in the control group received fluid management based on the clinical information alone. Those in the BIS group received BIS-guided fluid management along with clinical information. Results The subjects ( N = 137, mean age 51.3 ± 12.8 years, 54% male) were randomly assigned to the BIS group ( n = 67) or to the control group ( n = 70). There were no significant differences between the 2 groups with regard to age, sex ratio, cause of kidney failure, duration of PD, baseline comorbidity, RRF, PD method, or peritoneal transport type. At baseline, the 2 groups were not different in terms of RRF (glomerular filtration rate [GFR], 5.1 ± 2.9 vs 5.5 ± 3.7 mL/min/1.73 m2). After follow-up, changes in the GFR between the 2 groups were not different (-1.5 ± 2.4 vs -1.3 ± 2.6 mL/min/1.73 m2, p = 0.593). Over the 1-year study period, both groups maintained stability of various fluid status parameters. Between the 2 groups, there were no differences in the net change of various fluid status parameters such as overhydration (OH) and extracellular water/total body water (ECW/TBW). A net change in ECW over 1 year was slightly but significantly higher in the control group (net increase, 0.57 ± 1.27 vs 0.05 ± 1.63 L, p = 0.047). However, this difference was not translated into an improvement in RRF in the BIS group. There were no differences in echocardiographic parameters or arterial stiffness at the end of follow-up. Conclusion Routine BIS-guided fluid management in non-anuric PD patients did not provide additional benefit in volume control, RRF preservation, or cardiovascular (CV) parameters. However, our study cannot be generalized to the whole PD population. Further research is warranted in order to investigate the subpopulation of PD patients who may benefit from routine BIS-guided fluid management.

La pratique soignante en unité pour malades difficiles invite à la réflexion sur la singularité des relations cliniques qui peuvent s’y instaurer. Dans un contexte où le patient est dans le refus et parfois l’opposition agressive aux soins, comment aborder la question de l’alliance thérapeutique ? Une situation clinique permet ici d’illustrer la complexité du tissage de ce lien dans deux espaces de soin médiatisés que sont l’ergothérapie et la psychomotricité.
Athletic Training Students' and Preceptors' Perceptions of Active Learning Time and Bug-In-Ear Technology During Clinical Education Experiences
Authors: Nottingham Sara L. , Kasamatsu Tricia M. , Montgomery Melissa M. 
Published: February 2018

Context:
Engaging clinical experiences that allow extensive active learning and patient care interactions are important for the professional development of athletic training students. Understanding students' use of clinical time is important when attempting to improve these experiences.

Objective:
To gain participants' perspectives on active learning during clinical education both with and without the use of bug-in-ear technology.

Design:
Qualitative.

Setting:
Three high schools, 2 rehabilitation clinics, 1 university, and 1 community college clinical sites within 3 Commission on Accreditation of Athletic Training Education–accredited undergraduate athletic training programs.

Patients or Other Participants:
Thirteen athletic training students (11 female, 2 male; 22 ± 2 years old, 2 ± 1 years enrolled in the current accredited athletic training program) and 8 preceptors (5 female, 3 male; 35 ± 10 years old, 3 ± 3 years of experience as a preceptor) volunteered for this study.

Main Outcome Measure(s):
After observation of the participants' clinical education experiences, individual in-person interviews were audiorecorded and transcribed verbatim. We used an inductive process of open, axial, and selective coding to identify themes. Trustworthiness was established with member checking, multiple-analyst triangulation, and data source triangulation.

Results:
Three themes emerged from the data. Participants recognize that students spend much of their clinical time interacting with patients, completing administrative tasks, and doing custodial work. Participants noted their awareness of student activities increased after using the active learning assessment instrument. Lastly, participants perceived that bug-in-ear technology improved the efficiency of task completion but not the actual tasks completed.

Conclusions:
Since several factors influence the amount of active learning time spent during students' clinical education, athletic training programs may benefit from looking at their own students' time spent during clinical education. Asking students and preceptors to assess active learning time may help them and clinical education coordinators identify ways to increase active learning and decrease unengaged and managerial time.
Roles of Mentoring for Novice Athletic Training Faculty Members
Authors: Nottingham Sara L. , Mazerolle Stephanie M. , Barrett Jessica L. 
Published: February 2018

Context:
Mentorship is a valuable resource for athletic trainers who are transitioning to new roles such as a student, preceptor, or autonomous clinician. While mentorship has been identified as an important component of education, little is known about the role of mentorship during the transition from doctoral student to faculty member during the first several years in academia.

Objective:
Obtain faculty members' perspectives on the role of mentorship as it relates to their experiences as a tenure-track faculty member.

Design:
Qualitative, phenomenological research.

Setting:
Higher education institutions with Commission on Accreditation of Athletic Training Education-accredited programs.

Patients or Other Participants:
Twelve novice faculty members (9 female, 3 male) and 12 experienced faculty members (3 female, 9 male) participated in this study.

Main Outcome Measure(s):
We developed and piloted an interview guide designed to gain participants' perspectives on their experiences with and perceptions of mentorship in relation to their faculty roles and responsibilities. Semistructured telephone interviews were completed with each individual and transcribed verbatim. Data were analyzed using a phenomenological approach, and saturation was obtained. Trustworthiness was established with the use of member checking, multiple-analysts triangulation, and data source triangulation.

Results:
Two themes emerged regarding roles of mentorship: (1) support and guidance and (2) navigating institutional politics and expectations. Mentors supported novice faculty members in their responsibilities of teaching, research, and service, particularly when mentees perceived a weakness in 1 area. Mentors also helped novice faculty members navigate the tenure and promotion process and politics of their institution.

Conclusions:
Mentorship appears to be an important mechanism of support for novice faculty members as they transition to their tenure-track faculty roles. Mentorship appears to be particularly valuable when there is a perceived lack of preparation for 1 aspect of a faculty position. Novice faculty members should seek out mentors within and beyond their institution for support.
Right-handed Hopf algebras and the preLie forest formula
Authors: Menous Frédéric , Patras Frédéric 
Published: February 2018

Three equivalent methods allow to compute the antipode of the Hopf algebras of Feynman diagrams in perturbative quantum field theory (QFT): the Dyson–Salam formula, the Bogoliubov formula, and the Zimmermann forest formula. Whereas the first two hold generally for arbitrary connected graded Hopf algebras, the third one requires extra structure properties of the underlying Hopf algebra but has the nice property to reduce drastically the number of terms in the expression of the antipode (it is optimal in that sense).
The present article is concerned with the forest formula: we show that it generalizes to arbitrary right-handed polynomial Hopf algebras. These Hopf algebras are dual to the enveloping algebras of preLie algebras – a structure common to many combinatorial Hopf algebras which is carried in particular by the Hopf algebras of Feynman diagrams.

Abstract. The study of persistent organic pollutants (POPs) in low-latitude tropical and subtropical urban cities is necessary to assess their local and global impacts on ecosystems and human health. Despite studies on levels of POPs in water, soils, and sediments, analysis of the distribution patterns, seasonality, and sources of POPs in urban regions of Nepal remain limited. Polyurethane foam (PUF)-based passive air samplers were deployed in three major cities in Nepal: Kathmandu (the capital city), Pokhara, and Hetauda (agricultural cities). Dichlorodiphenyltrichloroethane (DDT) and hexachlorocyclohexane (HCH) were the dominant organochlorine pesticides in the atmosphere at all sites. The average concentrations of POPs were  ∑ DDTs, 8.7–1.0  ×  103 pg m−3;  ∑ HCHs, 5.3–3.3  ×  103 pg m−3; HCB, 5.8–3.4  ×  102 pg m−3;  ∑ endosulfan, BDL–51 pg m−3; and  ∑ 6PCBs, 1.4–47 pg m−3. Isomer and metabolite ratio analyses suggested that the concentrations present were from both new and historical applications of the POPs. Vegetable production sites and their market places appeared to be the major DDT and HCH source areas. Higher atmospheric concentrations of DDT and HCH occurred during the pre-monsoon and monsoon seasons, and winter, respectively, closely associated with their local application for soil preparation and vegetable spraying. The estimated travel distances of the POPs (HCB, α-HCH, γ-HCH, and p, p′-DDT) under the Nepalese tropical climate were all above 1000 km, suggesting that high precipitation levels in the tropical climate were not enough to scavenge the POPs and that Nepal could be an important source region for POPs. Due to their close proximity and cold trapping (driven by low temperatures), the high Himalayas and the Tibetan Plateau are likely the key receptors of POPs emitted in Nepal. These results add to the information available on POPs from tropical developing countries.

Abstract. Soil is a major contributor to the biosphere–atmosphere exchange of carbonyl sulfide (COS) and carbon monoxide (CO). COS is a tracer with which to quantify terrestrial photosynthesis based on the coupled leaf uptake of COS and CO2, but such use requires separating soil COS flux, which is unrelated to photosynthesis, from ecosystem COS uptake. For CO, soil is a significant natural sink that influences the tropospheric CO budget. In the boreal forest, magnitudes and variabilities of soil COS and CO fluxes remain poorly understood. We measured hourly soil fluxes of COS, CO, and CO2 over the 2015 late growing season (July to November) in a Scots pine forest in Hyytiälä, Finland. The soil acted as a net sink of COS and CO, with average uptake rates around 3 pmol m−2 s−1 for COS and 1 nmol m−2 s−1 for CO. Soil respiration showed seasonal dynamics controlled by soil temperature, peaking at around 4 µmol m−2 s−1 in late August and September and dropping to 1–2 µmol m−2 s−1 in October. In contrast, seasonal variations of COS and CO fluxes were weak and mainly driven by soil moisture changes through diffusion limitation. COS and CO fluxes did not appear to respond to temperature variation, although they both correlated well with soil respiration in specific temperature bins. However, COS : CO2 and CO : CO2 flux ratios increased with temperature, suggesting possible shifts in active COS- and CO-consuming microbial groups. Our results show that soil COS and CO fluxes do not have strong variations over the late growing season in this boreal forest and can be represented with the fluxes during the photosynthetically most active period. Well-characterized and relatively invariant soil COS fluxes strengthen the case for using COS as a photosynthetic tracer in boreal forests.
Representation of solar tides in the stratosphere and lower mesosphere in state-of-the-art reanalyses and in satellite observations
Authors: Sakazaki Takatoshi , Fujiwara Masatomo , Shiotani Masato 
Published: February 2018

Abstract. Atmospheric solar tides in the stratosphere and the lower mesosphere
are investigated using temperature data from five state-of-the-art
reanalysis data sets (MERRA-2, MERRA, JRA-55, ERA-Interim, and CFSR)
as well as TIMED SABER and Aura MLS satellite
measurements. The main focus is on the period 2006–2012 during
which the satellite observations are available for direct comparison
with the reanalyses. Diurnal migrating tides, semidiurnal migrating
tides, and nonmigrating tides are diagnosed. Overall the reanalyses
agree reasonably well with each other and with the satellite
observations for both migrating and nonmigrating components,
including their vertical structure and the seasonality. However, the
agreement among reanalyses is more pronounced in the lower
stratosphere and relatively weaker in the upper stratosphere and
mesosphere. A systematic difference between SABER and the reanalyses is
found for diurnal migrating tides in the upper stratosphere and the
lower mesosphere; specifically, the amplitude of trapped modes
in reanalyses is significantly smaller than that in SABER, although
such difference is less clear between MLS and the reanalyses. The
interannual variability and the possibility of long-term changes in
migrating tides are also examined using the reanalyses during
1980–2012. All the reanalyses agree in exhibiting a clear quasi-biennial oscillation (QBO) in the tides, but the most significant
indications of long-term changes in the tides represented in the
reanalyses are most plausibly explained by the evolution of the
satellite observing systems during this period. The tides are also
compared in the full reanalyses produced by the Japan Meteorological
Agency (i.e., JRA-55) and in two parallel data sets from this agency:
one (JRA-55C) that repeats the reanalysis procedure but without any
satellite data assimilated and one (JRA-55AMIP) that is
a free-running integration of the model constrained only by observed
sea surface temperatures. Many aspects of the tides are closer in
JRA-55C and JRA-55AMIP than these are to the full reanalysis JRA-55,
demonstrating the importance of the assimilation of satellite data
in representing the diurnal variability of the middle atmosphere. In
contrast to the assimilated data sets, the free-running model has no
QBO in equatorial stratospheric mean circulation and our results
show that it displays no quasi-biennial variability in the tides.
Water, energy and agricultural landuse trends at Shiroro hydropower station and environs

Published: February 2018

Abstract. The study examines the interplay among water resources, hydropower generation and agricultural landuse at the Shiroro hydropower station and its environs, in north-central Nigeria. Non-parametric trend analysis, hydropower footprint estimation, reservoir performance analysis, change detection analysis, and inferential statistics were combined to study the water-energy and food security nexus. Results of Mann–Kendall test and Sen's slope estimator for the period 1960 to 2013 showed a declining rainfall trend at Jos, around River Kaduna headwaters at −2.6 mm yr−1, while rainfall at Kaduna and Minna upstream and downstream of the reservoir respectively showed no trend. Estimates of hydropower footprint varied between 130.4 and 704.1 m3 GJ−1 between 1995 and 2013. Power generation reliability and resilience of the reservoir was 31.6 and 38.5 % respectively with year 2011 being the most vulnerable and least satisfactory. In addition to poor reliability and resilience indices, other challenges militating against good performance of hydropower generation includes population growth and climate change issues as exemplified in the downward trend observed at the headwaters. Water inflow and power generation shows a weak positive relationship with correlation coefficient (r) of 0.48, indicating less than optimal power generation. Total area of land cultivated increased from 884.59 km2 in 1986 prior to the commissioning of the hydropower station to 1730.83 km2 in 2016 which signifies an increased contribution of the dam to ensuring food security. The reality of reducing upstream rainfall amount coupled with high water footprint of electricity from the reservoir, therefore requires that a long term roadmap to improve operational coordination and management have to be put in place.

Published: February 2018

Abstract. The Gash Delta Spate Irrigation System (GDSIS), located in eastern Sudan with a net command area of 100 000 ha (an area currently equipped with irrigation structures), was established in 1924. The land is irrigated every 3 years (3-year rotation) or every 2 years (2-year rotation) so that about 33 000 or 50 000 ha respectively can be cultivated annually. This study deals with assessing the performance of the 3- and 2-year rotation systems using the Monte Carlo simulation. Reliability, which is a measure of how frequently the irrigation water supply satisfies the demand, and vulnerability, which is a measure of the magnitude of failure, were selected as the performance criteria. Combinations of five levels of intake ratio and five levels of irrigation efficiency for the irrigation water supply of each rotation system were analysed. Historical annual flow data of the Gash River for 107 years were fit to several frequency distributions. The Weibull distribution was the best on the basis of the Akaike information criteria and was used for simulating the ensembles of annual river flow. The reliabilities and vulnerabilities of both rotation systems were evaluated at typical values of intake ratio and irrigation efficiency. The results show that (i) the 3-year rotation is more reliable in water supply than the 2-year rotation, (ii) the vulnerability of the 3-year rotation is lower than that of the 2-year rotation and (iii) therefore the 3-year rotation is preferable in the GDSIS. The sensitivities of reliability and vulnerability to changes in intake ratio and irrigation efficiency were also examined.
