Es indiscutible, el rol que juega la flora y particularmente las plantas medicinales en la mejora de la calidad de vida de la población mundial. En Perú el saber sobre las plantas y sus aplicaciones se ha trasmitido a través de la historia y hoy en día constituye un legado heredado por las comunidades Andino-amazónicas, las cuales son poseedores de una flora excepcional, única y promisoria; y lamentablemente estas tradiciones se están perdiendo paulatinamente, sobre todo por la expansión demográfica. Por lo descrito, esta investigación tiene como objetivo determinar la importancia de la Flora medicinal promisoria de Jesús, Cajamarca, Perú. Para ello, se aplicaron 96 entrevistas semiestructuradas, mediante la técnica “bola de nieve”, a fin de recabar datos referentes a caracteres taxonómicos: familia, nombre científico y común, así como caracteres etnomedicinales: parte utilizada, tipo de preparación, forma de administración, enfermedad o dolencia tratada, e índice de Valor de Uso, de cada especie. Se reporta para el distrito de Jesus, 24 especies de flora medicinal promisorias, distribuidas en 23 géneros y 18 familias; siendo, las más representativas por su número de especies, las Asteraceae (3), Lamiaceae (3) y Fabaceas (2). Finalmente, de este total, 18 especies promisorias, fueron consideradas como importantes por el poblador del distrito de Jesus, según su Índice de Valor de uso (IVU).
INFORMATION THREATS TO THE STABILITY OF POLITICAL SYSTEM IN THE NORTHERN CAUCASUS
Authors: Salgiriev Ali , Gaziev Vakha , Soltamuradov Magomed , Galbatsov Sultan
Published: December 2020

In the Northern Caucasus, political elites traditionally play a key role in managing political processes, prevent and resolve conflicts, counter sociocultural threats, terrorism, and political extremism. The stability of the political system depends on the degree of political elites’ responsibility and their ability to negotiate with the federal political and administrative elite and to relay the interests of society. New threats to the normal functioning of state authorities are currently emerging, indicating the inefficiency of Russia’s policy aimed at preventing information security threats. In recent years, active social strata (mainly young people) have been mobilized with the aim of overthrowing legitimate authorities and objectionable politicians, changing regimes, etc., using modern network technologies, disinformation and fake news. Due to its historical and socio-cultural characteristics, as well as poly-confessional structure, the population of the Northern Caucasus is highly sensitive to territorial issues, as well as issues of religion, culture, ethnic relations, etc. In many respects, information technologies determine the position and power of high-status actors, primarily political elites, within the political system.
THE IMPACT OF REMITTANCES FROM ABROAD ON SOCIO-ECONOMIC DEVELOPMENT IN TAJIKISTAN
Authors: Khramova Marina , Ryazantsev Sergey , Rakhmonov Abubakr , Kasymov Osim
Published: December 2020

The relevance of this article is due to the importance of labor migration and remittances from migrant workers for the economy of Tajikistan. The purpose of the article is to determine the impact of remittances on living standards in Tajikistan at both the national and local levels. It is known that labor migration has become a significant socio-economic phenomenon for the country and society, involving a large part of Tajikistan’s population. Using statistical and sociological research methods, the authors show the key trends and the scale of labor emigration from Tajikistan in 1990-2020, as well as the socio-demographic structure of migrant worker flows from Tajikistan to the Russian Federation and other countries, with identification of a new trend towards a reorientation of migration flows to OECD countries. It has been established that migrant remittances have a positive impact on GDP growth, helping to open small businesses, develop entrepreneurship, create new jobs in the private sector, and boost construction. Remittances stimulate additional consumption: migrant workers’ households have more opportunities to meet their basic needs for food, consumer goods and durables, education, etc. The negative impact of remittances is that they actually help to meet only current needs, while the creation of new, high-technology jobs is slow and insufficient, lagging behind population growth. The country thus becomes hostage to external market conditions: the demand for foreign labor and crisis phenomena in the receiving countries.

Yemlere kestane ve mimoza tanen ekstraktı ilavesinin bazı in vitro rumen fermentasyon parametreleri üzerine etkileri
Authors: Günal Mevlüt
Published: December 2020

Amaç: Bu araştırmada; mimoza ve kestane tanen ekstraktı ilavesinin rumen fermentasyonu üzerine olan etkilerinin incelenmesi amaçlanmıştr.Yöntem ve Bulgular: Rumen sıvısına 0, 25, 50 ve 75 g/kg kuru madde (KM) dozlarında mimoza ve kestane tanen ekstraktı ilavesinin in vitro gaz üretimi, kuru madde sindirilebilirliği, mikrobiyal protein üretimi ile rumen fermentasyonu üzerine olan etkileri incelenmiştir. Rumen sıvısına 25 g/kg KM tanen ekstraktı ilavesi amonyak (NH3) hariç fermentasyon parametreleri üzerinde etkili olmamıştır (P>0.05). Buna karşın rumen sıvısına 75 g/kg KM tanen ekstraktı ilavesi yavaş bir sekilde fermentasyona uğramış kısımdan elde edilen gaz miktarı, potansiyel gaz üretimi ve rumen sıvısı parametrelerinden toplam uçucu yağ asitleri (UYA), asetik asit, butirik asit, asetik/ propiyonik asit oranı, NH3 düzeyi ile karbondioksit (CO2) ve metan (CH4) gazı üretimini önemli düzeyde azaltmıştır (P<0.01). Kestane tanen ekstrakt ilavesiyle karşılaştırıldığında mimoza tanen ekstrakt ilavesi NH3 düzeyi (P<0.01), yavaş bir sekilde fermantasyona uğramış kısımdan elde edilen gaz miktarı ile CH4 miktarıını düşürmüş (P<0.05), propiyonik asit miktarını artırmış (P<0.01), toplam UYA, isobütirik asit, kuru maddenin gerçek sindirim derecesi ile asetik/propiyonik asit oranını ise düşürme eğilimine yöneltmiştir (P>0.05).Genel Yorum: Sonuç olarak, ruminant beslemede 50 g/kg KM’a kadar tanen ekstraktının rasyonda kullanılmasının uygun olacağı, daha yüksek dozda kullanılması durumunda rumen fermentasyonu ve yemden yararlanmayı olumsuz etkileyebileceği, mimoza tanen ekstraktının NH3 ve CH4 üretimindeki düşürücü etkisinin kestane tanen ekstraktından daha yüksek olduğu söylenebilir. Çalışmanın Önemi ve Etkisi: Tanenler kaynağı ve dozuna bağlı olarak, mikrobiyal fermentasyon ve rasyon sindirilebilirliğini düşürebilir. Buna karşın kestane yada mimoza tanen ruminant rasyonlarına uygun düzeylerde katıldığı zaman, ruminal fermentasyon olumsuz etkilenmeksizin CH4 ve NH3 salınımının düşürülmesine yardımcı olabilir.

Published: December 2020

Amaç: Bitkilerin yaprak alanının belirlenmesinde kullanılan basit, doğru ve bitkiye zarar vermeyen yöntemler, birçok deneysel karşılaştırmada önemli yer tutmaktadır. Bu çalışmada serada yetiştirilen kavun bitkisinin farklı kalsiyum düzeyleri (0, 5, 10, 20 ve 30 kg/da) ve farklı sulama suyu miktarları (I50, I75, ve I100) altında yaprak alan modellerinin geliştirilmesi ve bu modelden faydalanılarak bitkilere zarar vermeden yaprak alanlarının belirlenmesi amaçlanmıştır.Yöntem ve Bulgular: Bu amaçla her uygulamadan 30’ar adet yaprak toplanmış (toplam 1350 adet) ve bu yaprakların en (W) ve boy (L) ölçümleri dijital kumpasla yapılırken, yaprak alanı (LA) ölçümleri dijital planimetre ile yapılmıştır. Yaprak eni, yaprak boyu ve yaprak alanı değerleri arasındaki ilişkiler MS-Excel 2010 (Microsoft Inc.) yazılımı ile grafiksel olarak incelenmiştir. Yaprak eni, yaprak boyu ve yaprak alanı değerleri arasındaki matematiksel tahmin modelleri ise; Unscrambler yazılımında (Versiyon 9.7, Camo Software, Norway) MLR (Multiple Linear Regression) yöntemine göre oluşturulmuştur. Tahmin modelinin doğrulanması için Tam Çapraz Geçerlilik (Full Cross Validation) yöntemi uygulanmıştır. Modellerin karşılaştırılması amacıyla her bir model için Unscrambler yazılımından elde edilen RMSEP (Root Mean Square Error of Prediction) ve R2 değerleri kullanılmıştır. Kısıtlı su uygulamalarının ortalama yaprak alanını azalttığı belirlenmiş ve bu bağlamda en başarılı modelin; Yaprak Alanı (cm2) = 0.3375 * (W2 + L2) - 0.3539 (RMSEP = 15.76 ve R2 = 0.97) olduğu belirlenmiştir.Genel Yorum: Oluşturulan matematiksel model yardımıyla özellikle bitki gelişimi ile ilgili tüm tarımsal araştırmalarda çok pahalı cihazlarla ve/veya bitki sökümü yapılarak gerçekleştirilebilen bitki yaprak alanları ve Yaprak Alan İndeksi (LAI) değerleri basit doğrudan ölçümlerle belirlenebilecektir. Aynı zamanda yetiştirme sezonu boyunca aynı yaprak üzerinde ölçümlerin alınması da mümkün olabilecektir.Çalışmanın Önemi ve Etkisi: Bu çalışma ile bilgisayara yükleyebildiğimiz basit bir yazılım sayesinde kavunda yaprak alan ölçümlerinin daha kısa sürede ve daha az hata ile sonuçlandırılması amaçlanmıştır. Elde edilen verilerle geliştirilen model yardımıyla kavun üzerinde yapılacak fizyolojik, morfolojik ve diğer çalışmalarda kullanılan toplam yaprak alanının hesaplanmasında özellikle araştırma yapan bilim insanlarına faydalı olacaktır. Bu çalışmadan yararlanılarak ve benzer yöntemlerle diğer bitkiler içinde model oluşturmak mümkün olacaktır.

The escalation of an armed conflict: a look at the antecedents of the confrontation between the Colombian state and the FARC
Authors: Cano-Holguín Nelson , Jiménez-Osorio Javier
Published: December 2020

With one of the longest-running conflicts in the Western Hemisphere, the Colombian state has been facing an internal armed conflict against the FARC since the 1950s. Four milestones set the framework for the most important background in this conflict. The first one, with the murder of leader Jorge Eliecer Gaitan, unleashed acts of severe violence between liberals and conservatives; then, the second milestone was due to the creation of the “national front” that ended the disputes by rotating power between these political parties; however, other minority groups were not taken into account, giving rise to the third milestone, where the FARC guerrillas emerged by claiming a communist model, and the fourth milestone corresponds to heavy military strikes against this guerrilla group that forced the FARC to a negotiate peace accord. Considering the theory of escalation and stagnation of the armed conﬂict, this article aims at summarizing the background that has led to this conﬂict, which had its beginnings in political disputes but gradually escalated to become a serious problem that the country has been suﬀering.

“DECRÈPITA I TEATRAL”? ON LITERARY EXPLORATIONS OF BARCELONA
Authors: Bou Enric
Published: December 2020

Two novels, Montserrat Roig’s El temps de les cireres (1976) and Luis Goytisolo’s Recuento (1973), provide numerous examples of how walking in the city can be a particularly significant experience, profoundly marked by history and politics. This article discusses the ways that Roig and Goytisolo guide their characters and readers into an urban jungle of words with a very precise purpose: the critical interpretation of space according to the values of the writer in the present. Proffering a quasi-archeological reading of a jumble of temporal traces scrawled on the walls of old buildings, Goytisolo’s narrator expresses, in a manner not unlike that of Roig’s characters, a complex mise en question of the past and the present. In Roig’s novel, what comes to the fore is the funereal-like theatricality of the old Ribera neighborhood, which functions not only as a space of habitation but also as a setting for cultural memory and the representation of Catalan history.
BARCELONA, TERRA DE PROMISSIÓ: EL DESCOBRIMENT DE L’ANONIMAT
Authors: Barbal Maria
Published: December 2020

The massive emigration of people from villages, towns, and small cities to the metropolis of Barcelona in the 1960s has constituted the primary motivation for my writing. In the fol1owing article, I reflect on the various meanings that movement to the Catalan capital has for the characters in three of my novels: Pedra de tartera, Càmfora, and Carrer Bolívia. The city becomes a home and a dream; it becomes a site of anonymity full of challenges and promises; it becomes, in short, a test of adaptation. There is no real return to the point of departure, only the transformation of the individual citizen and of the urban body.
Database “Pro-family (pronatalist) communities in the social network VKontakte”
Authors: Kalabikhina Irina E. , Banin Evgeny P.
Published: December 2020

The database contains uploading text comments from the social network VKontakte in .csv format (UTF-8 encoding). The comments are collected from communities discussing pregnancy, childhood, motherhood, etc. Uploading contains comments to posts with which the interaction took place. The absolute number of likes was used as a criterion (comments were collected where the number of likes is greater than or equal to 5). Text data was pre-processed (stemmization and lemmatization).

The data is suitable for thematic analysis (e.g. LDA – Latent Dirichlet Allocation), for modelling the graph structure of communities (the link_comment variable contains a unique post identifier, link_author contains a unique user identifier), for analysis of tonalities of statements and formation of a dictionary of demographic connotation in Russian. Analysis of the tonalities of statements enables measuring the dynamics of “demographic temperature” in pro-family (pronatalist) communities.
†Camelosphecia gen. nov., lost ant-wasp intermediates from the mid-Cretaceous (Hymenoptera, Formicoidea)
Authors: Boudinot Brendon E. , Perrichot Vincent , Chaul Júlio C. M.
Published: December 2020

Fossils provide primary material evidence for the pattern and timing of evolution. The newly discovered “beast ants” from mid-Cretaceous Burmite, †Camelospheciagen. nov., display an exceptional combination of plesiomorphies, including absence of the metapleural gland, and a series of unique apomorphies. Females and males, represented by †C. fossorsp. nov. and †C. venatorsp. nov., differ in a number of features which suggest distinct sexual biologies. Combined-evidence phylogenetic analysis recovers †Camelosphecia and †Camelomecia as a clade which forms the extinct sister group of the Formicidae. Notably, these genera are only known from alate males and females; workers, if present, have yet to be recovered. Based on ongoing study of the total Aculeata informed by the beast ant genera, we provide a brief diagnosis of the Formicoidea. We also provide the first comprehensive key to the major groupings of Mesozoic Formicoidea, alongside a synoptic classification in which †Zigrasimeciinaestat. nov. and †Myanmyrma marauderacomb. nov. are recognized. Finally, a brief diagnosis of the Formicoidea is outlined.

Authors: Song Weilin , Chen Andrew X. , Conti Thais F. , Greenlee Tyler E. , Hom Grant L. , Rachitskaya Aleksandra V. , Singh Rishi P.
Published: December 2020

BACKGROUND AND OBJECTIVES:

This study aims to characterize check-in kiosk usage within a multi-disciplinary ophthalmic clinic.

PATIENTS AND METHODS:

Chart review of patients aged 18 or older seen at Cole Eye Institute, Cleveland Clinic, from August 1, 2019, to October 31, 2019. Primary endpoint was percentage of patients who used a check-in kiosk. Secondary endpoints were demographic characteristics and visual acuity (VA) of the two groups.

RESULTS:

Of 13,752 patients, 3,542 (26%) used a check-in kiosk. Kiosk users were significantly younger than kiosk non-users (median [interquar-tile range (IQR)]: 63.6 [49.4–72.6] vs. 66.6 [55.0–75.4];
P
< .0001), had a lower proportion of Medicaid patients (282 [8%] vs. 930 [10%];
P
< .0001), and lived in areas with a greater median income (mean [± standard error]: $58,421 [± 399) vs. $54,992 [±236];
P
< .0001). On average, they also had better VA (mean ETDRS [95% confidence interval]: 80.5 [80–80.9] vs. 78.3 [78–78.6];
P
< .0001).

CONCLUSIONS:

Significant demographic and VA differences were observed between kiosk users and non-users and may influence kiosk usage.

Macular Sequelae Following Exudative Retinal Detachment After Laser Photocoagulation for Retinopathy of Prematurity
Authors: Zhang David L. , Shapiro Michael J. , Schechet Sidney A. , Rabiah Peter K. , Rodriguez Sarah H. , Blair Michael P.
Published: December 2020

BACKGROUND AND OBJECTIVE:

To report a series of exudative retinal detachments (ERDs) following laser photocoagulation for retinopathy of prematurity (ROP).

PATIENTS AND METHODS:

Retrospective case series.

RESULTS:

Eleven eyes of seven infants were identified who developed ERD following laser. Median gestation age was 25 weeks (interquartile range [IQR]: 24–27 weeks), and median birth weight was 662 grams (IQR: 538–850 grams). Median postmenstrual age at time of laser was 35 weeks (IQR: 33–39 weeks). ERD was diagnosed at a median of 7 days (IQR: 5–7 days) after laser and was managed with steroids. Bevacizumab was also used for certain cases. Time to resolution ranged from 1 to 5 weeks. Macular pigment changes, atrophy, window defect on fluorescein angiography, and photoreceptor loss on optical coherence tomography were noted in some cases following ERD resolution. Excluding one patient who expired at 3 months, median length of follow-up was 10 years (IQR: 9–13.5 years). Overall, only one patient, who presented with less severe ERD, had normal vision.

CONCLUSIONS:

ERD is an uncommonly reported complication following laser for ROP. Macular changes following ERD resolution may have negative visual consequences.

The Extent of Retinal Involvement of Canthaxanthin Crystalline Retinopathy Demonstrated by Multimodal Imaging
Authors: Iyer Prashanth G. , Shen Mengxi , Trivizki Omer , Barikian Anita , Chaudhry Amina , Rosenfeld Philip J. , Yehoshua Zohar
Published: December 2020

Limited information is known about the extent of canthaxanthin crystalline retinopathy on the retinal layers. The authors describe a 51-year-old woman who was taking canthaxanthin for tanning purposes for 7 years. Three years after cessation of this agent, she presented with asymmetric crystalline retinopathy affecting both eyes. She was lost to follow-up, and upon returning 4 years later, the crystalline retinopathy persisted but the number of crystals had decreased. Using swept-source optical coherence tomography, the authors showed that the crystalline retinopathy affected all retinal layers. In addition, retinal pigmented epithelial detachments were present suggesting persistent damage caused by the canthaxanthin.

Published: December 2020

Diffuse unilateral subacute neuroretinitis (DUSN) is a rare ocular infectious disease caused by migrating larvae of a nematode. DUSN is often a diagnostic challenge as it is difficult to identify the pathogenic nematode on funduscopic examination because it moves frequently and often resides within the subretinal space. Herein, the authors present a patient with unilateral, chronic visual loss who was noted to have a live, motile worm within the vitreous cavity. Initial attempts to treat with laser photocoagulation were unsuccessful. In the accompanying video, the authors report the first case of a live intraocular parasite successfully removed with pars plana vitrectomy.
The Brezis-Nirenberg type double critical problem for a class of Schrödinger-Poisson equations
Authors: Cai Li , Zhang Fubao
Published: December 2020

In this paper, we study the following Schrödinger-Poisson equations with double critical exponents:

   $ \begin{equation*} \left\{ \begin{array}{lr} -\Delta u = |u|^4u+\phi |u|^3 u +\lambda u,\quad& in\,\,\Omega,\\ -\Delta \phi = |u|^5,\quad& in\,\,\Omega,\\ u = \phi = 0,\quad& on\,\,\partial\Omega, \end{array} \right. \end{equation*} $

where $ \Omega $ is a bounded domain in $ \mathbb{R}^3 $ with Lipschitz boundary, $ \lambda $ is a real parameter satisfying suitable conditions. Using variational methods, we show the existence and nonexistence of nontrivial solutions for the Schrödinger-Poisson equations.

Published: December 2020

Las unidades de cirugía para experimentación animal son instalaciones complejas de planificar y diseñar. Es por ello que para afrontar un proyecto de este tipo resulta recomendable visitar o recopilar la información que se encuentra disponible sobre unidades similares ya construidas, para así poder analizar los diferentes modelos conceptuales y los flujos de trabajo que puedan servir de referencia. En este trabajo, a través de expresiones gráficas, se estudia el modelo organizativo, diseño conceptual y características constructivas de las unidades quirúrgicas experimentales de cinco Institutos de Investigación Sanitaria Acreditados por el Instituto de Salud Carlos III. A partir de la puesta en común de los resultados obtenidos del análisis de varios centros se pretende establecer unas pautas de comportamiento o protocolos que puedan ser de utilidad a los profesionales responsables del diseño, construcción y puesta en funcionamiento de nuevos quirófanos experimentales.

Late Roman Pottery from the Theatre of Nicaea in Bithynia
Authors: Meriç Aygün Ekin
Published: December 2020

The Roman theatre in Nicaea is the most famous and well preserved monument from the Roman Imperial Period which was built under the supervision of the Bithynia governor, Plinius, during the rule of Trajan.1 The examined Late Roman pottery was found in a rubbish dump which covered the theatre. Following the stratigraphy and dating of the dump it is estimated to be from between 368 A.D. and 557 A.D. There is a renovation of the colonnaded gallery probably after the earthquake of 368 A.D. which is mentioned in the records.2 Many coins of the fourth century A.D. which were found during excavations might also be related with this renovation. But further earthquakes resulted in the theatre being gradually destroyed and abandoned. It seems that the theatre was used as a rubbish dump after the late fourth century A.D. until the earthquake of 557 A.D. A great number of African Red Slip ware has been found in this fill of the theatre. The main ceramic types are plates and bowls –Hayes Forms 53, 61 and 67– which have recently been classified as Africana D by S. Tortorella. A small group of Phocean Red Slip Ware “Late Roman C”, mainly bowls, dated to early in the 4th century until its disappearance in the third quarter of the sixth century A.D. have also been attested in the theatre of Nicaea. There is some “Eastern Sigillata C”, mainly in Hayes 3, also discovered in this dump. We have discovered some Light Colored Ware fragments in the Nicaea theatre which appear to be quite similar to the ones found in Parion. Recently E. Ergürer has published a group of Light Colored Ware dated between the fifth early sixth centuries A.D. from Parion.3 The production center of this ware is not securely determined so far but it is interesting to note that this ware is quite common both in Bithynia, Propontis and the Troad. As a result the aforementioned wares, which are treated for the first time in Nicaea, were found in the same rubbish dump over the theatre and are dated between the late fourth century and third quarter of the sixth century A.D.
Early Chalcolithic Pottery from Tepecik-Çiftlik and Gelveri, Central Anatolia: From Local to Supra-Regional Ceramic Style
Authors: Godon Martin , Özbudak Ozan
Published: December 2020

We intend to decipher both a chronological and a cultural problematic raised by the sudden appearance of geometric incised decorations on Anatolian pottery, seemingly at the beginning of the sixth millennium cal B.C. Frequently designated as ‘Gelveri type’ in reference to the Gelveri-Güzelyurt Cappadocian pottery assemblage, the lack of a reliable chronology based on a good stratigraphy at the site made it difficult to cope with the nature of the development of such pottery style. Excavations at Tepecik-Çiftlik as well as recent archaeological work at Gelveri have provided us with new stratigraphic and decoration-related technological evidence. Hence, we have the possibility to analyse the emergence and the development of such pottery styles within a reliable archaeological context. Seen on such a large geographical scale, covering at least the entire Anatolian plateau, the nature of this pottery style development cannot be considered as a pottery phenomenon in itself only. It is necessary to investigate the cultural interactions at play, enabling stylistic patterns to be shared within different cultural areas.

Endourological treatment for urinary stones and other obstructive urinary tract diseases is minimally invasive but in some cases it involves serious complications. This collection of cases describes some complications of endourological procedures and how they were treated. Case 1: A case of right ultrasound-guided percutaneous nephrostomy found to be misplaced in the inferior vena cava. The case was safely managed, but it showed that ultrasound guidance alone may be insufficient so it is recommended that percutaneous nephrostomy should be always placed under fluoroscopic control, either alone or in combination with ultrasound guidance. Case 2: A case of renal subcapsular hematoma occurring on retrograde intrarenal surgery at high perfusion pressure. The hematoma was drained under combined ultrasonic and radiological guidance. Post treatment recovery was uneventful. Large stone size, severe ipsilateral hydronephrosis, long operation time, higher hydrostatic pressure of the irrigating solution and low ureteral wall compliance are supposed to be risks factors associated with renal subcapsular formation. Management strategy should be tailored to patient’s clinical conditions. In hemodynamically stable patients, large hematoma drainage is recommended to prevent further complications and favours early recovery. Case 3: A case of double J stent fracture discovered one month after the insertion to relieve obstruction from a 1 cm stone in the right proximal ureter. The distal fragment of the stent was removed by cystoscopy while the proximal fragment was removed by semirigid ureteroscopy in two sessions due to fever and extensive calcification. Case 4: A mini-invasive technique for transurethral replacement of completely encrusted urinary stents in female patients. This technique allows the interventional radiologist to replace obstructed urinary stents by avoiding more invasive and traumatic urological procedures with sedation.
Observational study on the effects of a topical formulation in patients with premature ejaculation

Published: December 2020

Premature ejaculation (PE) has been defined as the inability to control or delay ejaculation, resulting in dissatisfaction or distress of the patient. Although PE is the most frequent sexual dysfunction, it is still underdiagnosed. An accurate clinical history is the best diagnostic approach that, in the majority of cases, is enough to differentiate between primary and acquired PE. Nowadays, treatment is not curative but is effective in increasing the intravaginal ejaculatory latency time (IELT), improving the sexual satisfaction of the couple [...].
Lean Six Sigma and Athletic Training: A Primer for Athletic Training Educators
Authors: Noller Christine , Berry David C.
Published: December 2020

Context

Lean as a quality improvement philosophy is new to athletic training despite widespread use in health care for many years.

Objective

To introduce the concepts of Lean and Lean Six Sigma and create a primer document for athletic training educators in the classroom.

Background

Lean requires organizations to exercise effort along with several dimensions simultaneously to improve patient quality and efficiency while controlling costs and reducing waste. When appropriately executed, Lean transforms how an organization and its employees work, creating an avid quest for quality improvement and, ultimately, patient safety.

Synthesis

Lean is a cultural transformation that changes how an organization operates. It requires new habits, skills, and attitudes throughout the organization, from executives to front-line staff. Lean is a journey, not a destination. The culture of Lean involves the relentless pursuit of continuous quality improvement and is composed of 6 principles and numerous tools.

Recommendation(s)

Whether athletic trainers approach Lean or Lean Six Sigma in a leadership role, or as a stakeholder in a Kaizen event, all should have a working knowledge of the principles, methods, elements, philosophy, and tools of robust process improvement. Moreover, while no best-practice statement exists about how to incorporate Lean Six Sigma into a curriculum, addressing process improvement early may allow immersive-experience students an opportunity to engage in a process improvement initiative, facilitating a greater appreciation of the content, and offer opportunities to engage professionals from other disciplines.

Conclusion(s)

Lean is reproducible in sports medicine clinics, orthopedic practices, and outpatient and athletic health care facilities, but only when athletic trainers understand the application. Moreover, for this reason, athletic training programs should strongly consider adding a robust process improvement course/content to their graduate curriculums.
Tight frames and related geometric problems
Authors: Ivanov Grigory
Published: December 2020

A tight frame is the orthogonal projection of some orthonormal basis of
$\mathbb {R}^n$
onto
$\mathbb {R}^k.$
We show that a set of vectors is a tight frame if and only if the set of all cross products of these vectors is a tight frame. We reformulate a range of problems on the volume of projections (or sections) of regular polytopes in terms of tight frames and write a first-order necessary condition for local extrema of these problems. As applications, we prove new results for the problem of maximization of the volume of zonotopes.
On Moser’s regularization of the Kepler system: Positive and negative energies
Authors: Ferrer Sebastián , Crespo Francisco
Published: December 2020

We present a generalization of Moser’s theorem on the regularization of Keplerian systems that include positive and negative energies. Our approach does not consider the geodesics of the hyperboloid embedded in a Lorentz space for the unbounded orbits, as it is previously done in the literature. Instead, we connect the Keplerian positive and negative energy orbits with the harmonic oscillator with negative and positive frequencies. The connection is established through the canonical extension of the stereographic projection, as it is done in Moser’s original paper. How we base our study reveals that Kustaanheimo–Stiefel map KS and Moser regularizations are alternative ways of showing the spatial Kepler system as a subdynamics of the 4D harmonic oscillator.
