Ozelenela popotna palica svetega Krištofa
Authors: Dobravec Jurij
Published: October 2020

Christians have venerated St Christopher since the Middle Ages. His walking stick, used while crossing the river with the Christ Child on his shoulders, later sprouted and grew into a giant tree. Scholars prevailingly interpret the stick’s greening as a religious symbol. In this paper, I suggest a biological explanation, underpinned by the abilities of revitalisation inherent to many lignin plants species. Additionally, I show that planting the seemingly dry branch on a riverbank might hold environmental instructions about how to mitigate human-caused erosion or similar changes in nature. Being a patron of travellers, the ecological Saint Christopher might serve as a model for the needed greening of the fast-growing tourism industry.

Mӗgil·laṯ Ta‛anîṯ. Traducción, introducción y notas
Authors: Martínez Teresa
Published: October 2020

Traducción y comentario del texto de Mӗgil·laṯ Ta‛anîṯ: treinta y cinco versos en arameo palestino que mencionan una serie de fechas gloriosas en las que se prohibe ayunar. Documento antiguo, citado en la Mišnâ, de gran valor lingüístico e histórico, es la fuente más antigua y fiable para la historia de las luchas entre el judaísmo y el helenismo. Al parecer, se inició su redacción por orden de Alejandro Janeo, cuya victoria en Calcis (92 a. C.) se cita, y se continuó en época de los primeros hasmoneos. La redacción actual es anterior a la destrucción del segundo templo.
La justicia en las aljamas castellanas a fines del siglo XV: la frontera oriental del reino de Castilla
Authors: Cantera Montenegro Enrique
Published: October 2020

En este trabajo se aborda el estudio del mantenimiento del principio de la autonomía judicial en las aljamas judías de las comarcas más orientales de la Corona de Castilla a fines de la Edad Media. En contraste con el siglo XIII, puede apreciarse un paulatino retroceso en la capacidad de actuación de los jueces judíos, lo que obedece a una doble motivación: al decidido empeño de la autoridad monárquica de terminar con cualquier manifestación de autonomía judicial, como paso fundamental en la construcción del nuevo Estado, y a la propia desconfianza de los judíos hacia unos jueces demasiado sometidos a las presiones de las familias más poderosas de las aljamas.
Sevilla y los conversos: los «habilitados» en 1495
Authors: Ladero Quesada Miguel-Angel
Published: October 2020

Después de las revueltas contra los judíos de 1391 y de la intensa actividad catequética de los años 1407 a 1416, Sevilla, como otras ciudades andaluzas, pasó a tener una abundante comunidad judeoconversa que fue objeto de hostilidad y de diversas agresiones entre 1433 y 1474, por motivos religiosos que encubrían o comportaban también otros de carácter socioeconómico y de simple xenofobia. La Inquisición se entableció, a la vista de lo que ocurría en Andalucía, entre otras cosas para dar un cauce legal al problema y que no derivara en detrimento de la autoridad regia. El resultado de este trabajo, que utiliza como base una nómina de 1.750 conversos habilitados en Sevilla durante los últimos meses de 1494 y primeros de 1495, permite precisar cuestiones que hasta ahora permanecían o mal conocidas o erróneamente interpretadas.
Pantanal Transfronteiriço (Bolívia-Brasil- Paraguai) e as áreas protegidas: desafios da gestão diferenciada na zona de fronteira
Authors: Moretti Edvaldo Cesar , Gonçalves Karoline Batista
Published: October 2020

Este artigo visa analisar os desafios advindos do gerenciamento diferenciado das áreas protegidas localizadas na zona de fronteira do Pantanal Transfronteiriço (Bolívia- Brasil- Paraguai). No intuito de chegar a esse objetivo analisamos as políticas e leis voltadas à conservação de ambientes, os sistemas de gerenciamento de áreas protegidas e as principais iniciativas de conservação feitas pela Bolívia, Brasil e Paraguai. No tocante aos procedimentos metodológicos, esses envolveram uma combinação entre pesquisas de campo, entrevistas e pesquisas bibliográficas. Quanto à pesquisa de campo foram realizadas visitas às instituições governamentais responsáveis pelo gerenciamento das áreas protegidas nos três países, visita a algumas Organizações não Governamentais (ONGs), e posteriormente às áreas protegidas objeto desta análise, na qual realizamos entrevistas e coletamos dados e informações. Desse modo, observamos que as áreas protegidas analisadas interferem na dinâmica territorial deste ambiente e produzem novos territórios caracterizados pela apropriação, restrição do uso e iniciativas de conservação. Como resultado desse processo surgem conflitos que envolvem sujeitos, os Estados Nação e grupos de interesse. O que permite concluir que as ações e normativas voltadas ao gerenciamento das áreas protegidas nesta região devem levar em consideração a totalidade deste ambiente, pois a presença da fronteira é definida/identificada somente pelos sujeitos e não para os elementos da natureza.
Mobilidade espacial da população: Análise do fluxo de estudantes de nível superior nos centros regionais no interior de Minas Gerais
Authors: Lobo Carlos , Soares Rafael Santiago , Carvalho Paulo Fernando Braga
Published: October 2020

Ainda que a análise dos movimentos espaciais da população seja recorrente na ciência demográfica, sua manifestação no âmbito regional ainda merece atenção. Algumas questões relacionadas à mobilidade espacial da população motivada por estudo e/ou trabalho carecem de discussões: os municípios que receberam maior investimento na expansão do ensino superior no estado têm atraído um maior número de população residente ou “itinerante”? Quais são as dinâmicas de mobilidade para fins de estudo e trabalho associadas a estes centros regionais? Considerando tais questões, esse trabalho tem como objetivo analisar a mobilidade populacional nos cinco principais centros regionais quanto à oferta do ensino superior no interior do estado de Minas Gerais, partindo da hipótese de que a avaliação de diferentes fluxos populacionais (migração e pendularidade) é capaz de expressar a capacidade dos centros regionais na atração de estudantes. Para responder essas questões foram calculados cinco indicadores baseados em razões e proporções usando dados de pendularidade e migração do Censo de 2010 e, para análise espacial dos fluxos, os resultados foram representados cartograficamente. Os resultados mostram que os centros regionais exercem a força da centralidade ao atrair migrantes e pendulares por motivo de estudo no ensino superior e que a proximidade aos centros regionais favorece o movimento pendular.
Mudanças climáticas e impactos sócio-territoriais dos desastres glaciais na Cordilheira Branca, Peru
Authors: Figueiredo Anderson Ribeiro de , Simões Jefferson Cardia , Heidrich Álvaro Luiz , Menegat Rualdo
Published: October 2020

Este artigo discute o histórico de desastres naturais na Cordilheira Branca, Peru, durante o período 1970–2011. O estudo analisou dados gerais sobre desastres nesse intervalo de tempo e de maneira mais ampla os desastres glaciais entre 1725 e 2010 d.C. Historicamente, a região foi afetada por uma série de desastres glaciais que deixaram mais de 26 mil pessoas mortas. Assim, este artigo examina o impacto desses desastres glaciais, considerando que desencadeiam processos de desterritorialização e reterritorialização na região. As seguintes estratégias metodológicas foram adotadas: trabalho de campo; entrevistas semiestruturadas realizadas com sobreviventes dos desastres glaciais e com gestores ambientais; revisão da literatura sobre o tema. Sugere-se que as mudanças climáticas aumentam o risco de desastres glaciais. A partir desses relatos foi possível constatar que a desterritorialização implica na afetação do cotidiano dos habitantes, na quebra de relações e de vínculos com o lugar. Além disso, os desastres glaciais causam um processo abrupto de desterritorialização, consequentemente, uma reterritorialização que se desenvolverá mais lentamente, abrindo intenso campo de disputas entre os diferentes atores envolvidos, despertando conflitos sociais.
Diagnosis and treatment of penile injury: ten years experience of an emergency department
Authors: Panella Paolo , Pepe Pietro , Pennisi Michele
Published: October 2020

Introduction: To evaluate the imaging accuracy in the diagnosis and clinical management of penile injury.Materials and methods: From January 2010 to January 2020, 20 men (median age 40.2 years) were admitted to our Emergency Department with the diagnosis of penile injury; the penile trauma was related to sexual intercourse in 16 cases, masturbation in 3 cases and injury caused by the partner in 1 case. All the patients underwent accurate medical history, clinical examinations and diagnostic imaging. Color Doppler ultrasound (CDU) evaluation was performed by Logiq E9 ecograph (General Electric; Milwaukee, WI) supplied with a linear probe small (7.5-10 MHz); magnetic resonance image (MRI) examination was performed within 3-24 hours from the trauma using a 1.5 Tesla scanner, (ACHIEVA 3T; Philips Healthcare Best, the Netherlands) performing pre-contrast and post-contrast multi-planar turbo spin-echo T1 and T2-weighted sequences. Results: 15/20 (75%) men with high suspicion of the tunica albuginea rupture underwent surgical exploration; conversely, 5/20 (25%) patients underwent conservative management. CDU detected 11/15 (73%) fractures of the penis and in 8 of them the length of the rupture was underestimated (more than 5 millimeters). On the contrary, MRI diagnosed all the albuginea ruptures showed by surgical exploration, but underestimated the length of the lesions in 9/15 (60%) cases. The IIEF-5 score administered six months later penile trauma demonstrated a good performance in all the patients. Conclusions: In our series, all the patients with a tunica albuginea rupture < 5 mm. diagnosed by MRI were submitted to conservative management with a complete functional restitutio ad integrum.
Non-invasive removal of self-locking entrapped nephrostomy tubes
Authors: Campodonico Fabio , Rossi Umberto Geremia , Ennas Marco , Valdata Alessandro , Di Domenico Antonia , Pinna Francesco , Introini Carlo
Published: October 2020

Introduction: The removal of an encrusted nephrostomy tube can be a challenging maneuver. Urological literature is very bare in detailing techniques for removal of entrapped percutaneous catheters. We present a simple, safe and non-invasive technique of nephrostomy removal using a vascular introducer sheath, useful to manage complicated situations such as nephrostomies blocked for severe encrustations or disabled in their self-locking system. Surgical technique: The nephrostomy tube is cut and the stump is passed with a suture needle. The suture is passed through the inner vascular introducer sheath tip, and the introducer is then removed. The introducer sheath is advanced over the nephrostomy until joining the pigtail segment, under fluoroscopy guidance. Thus the suture is pulled out with strenght to contrast the opposite stiffness of the encrusted coil, until the nephrostomy has safely come out. Comment: The sheath exchange technique is quick, involves less manipulation through the perirenal fascia and kidney, and is suitable for different conditions of entrapped nephrostomies.
Management of complications in penile prosthesis reimplantation: A case report
Authors: Capretti Camilla , Avolio Antonio , Florio Alberto , Giovannozzi Silvia , De Carolis Domenico
Published: October 2020

A 74-years-old patient, without comorbidity, underwent malleable penile prosthesis (MPP) implantation in 2007. In 2015, after a perineal trauma, he experienced stress urinary incontinence, medial extrusion of the left prosthetic cylinder and an urethrocavernous fistula. The cylinder was removed and an artificial urinary sphincter (AUS) implanted, together with a three-component inflatable penile prosthesis (IPP). The left corpus cavernosum (CC) was significantly shorter than the right one due to fibrosis. After 8 months, partial lateral extrusion of the right prosthetic cylinder prompted a replacement with a shorter extensor. Six months after, a new diastasis of the ruptured area occurred due to a further CC shortening. The extensor was removed and the cylinder shortened, with a dermal graft applied to the area. Long-term patient satisfaction was high.
A global snapshot of endourology residency training
Authors: Aslam Asad Ullah , Philipraj Joseph , Jaffrey Sayed , Buchholz Noor
Published: October 2020

Background: Urology has become more complex over the last decades with surgical sophisticated technologies such as endoscopy, laparoscopy and robotic surgery. As these minimally invasive methods gain popularity throughout the world, this has led in some countries to a serious training gap as compared to other countries, and between generations of surgeons within national training systems. There is a huge heterogeneity in urological training between countries, whether developed or developing. This paper attempts to shed some light onto global urological training, comparing a significant number of various national systems, and to outline global tendencies in urological training. It will enable interested readers to see where their own system stands in international comparison, and hopefully enable them to identify training needs to achieve global quality standards. Materials and methods: This is a questionnaire-based assessment which was sent to 240 members of U-merge from 62 countries. In addition, there is ample literature on the requirements of structured training programs and assessments, and we have tried to briefly outline the key points in this paper. Results: We received responses from 32 countries Urology residency training is hugely heterogenous between countries. Only 44% of nations use a structured training program with assessments. Others use the Halstedian apprenticeship approach. Notably, some developing countries do use modern teaching and assessment methods, whereas some developed countries still use the outmoded apprenticeship model. For the interested reader, results have been tabled in detail, and training systems described country by country. Conclusions: Our results have shown a huge heterogeneity in quality urology training between countries and within continents. In systems without national structure of training, it can be assumed that such differences exist even between hospitals/ training institutions. There is no doubt in times of globalization with resident and doctor migration and exchanges that training needs structure and standardization. The still huge gap in developing countries to catch up and be able to afford latest surgical and learning technologies need to be addressed with the help of responsible outreach programs.
Nephroureterostomy as a treatment of obstructive uropathy: A single center experience
Authors: Khan Muhammad Faisal , Babar Maira Saeed , Tsampoukas Georgios , Misra Soumya
Published: October 2020

Objective: To report the outcomes of percutaneous nephroureterostomies performed in a single center a period of ten years. Materials and methods: We retrospectively collected and analyzed data for 52 nephroureterostomy procedures that were performed from September 2008 to August 2018. We present patient’s demographics, indications for the procedure, type of anesthesia, technical difficulties, length of stay in hospital and complications. Results: A total of 52 procedures including 13 bilateral nephroureterostomies were performed on 39 patients. Taking into account the need for replacement of nephroureterostomy procedures during the study period, total number of procedures was 168. Out of a total 39 patients, 32 (84%) of patients had advanced cancer. All procedures were performed as day cases using sedation and had no immediate or early complications. Ten patients or 16% (27 nephroureterostomies out of total 168 procedures) had minor complications. Conclusions: To the best of author’s knowledge, this is the largest case series reporting the outcome of percutaneous nephroureterostomies. We can therefore conclude that percutaneous nephroureterostomy is a useful palliative procedure to relieve ureteric obstruction, when other measures are not possible, and it has low incidence of complications. However, further studies are warranted to compare different procedures used to relieve ureteric obstruction.

MicroRNA-22 enhances the differentiation of mouse induced pluripotent stem cells into alveolar epithelial type II cells
Authors: Tao Fan , Wang Feng , Zhang Weichen , Hao Yaming
Published: October 2020

Considerable evidence has verified that microRNAs (miRNAs) play important roles in various cellular processes including differentiation. However, the regulatory roles of miRNAs involved in the differentiation of induced pluripotent stem cells (iPSC) into lung epithelial cells are still unknown. In this study, we first evaluated the current protocols to differentiate iPSC into alveolar epithelial type II (AEC II) cells, but the efficiency is low. We next identified that miR-22 can efficiently enhance the differentiation of iPSC into AEC II cells under the stimulation of proper growth factors and growing on appropriate matrix. Moreover, the AEC II cells generated from iPSC with miR-22 overexpression can proliferate and secrete lung surfactant. Here, we discovered a previously unknown interaction between miR-22 and iPSC differentiation but also provide a potential target for the effective derivation of AEC II from iPSCs for cell-based therapy.
Application of Color Doppler Ultrasound to Evaluate Chemotherapeutic Effect on Primary Thyroid Lymphoma
Authors: Hu Cheng-Chuan , Wang Chih-Wei , Chen Jia-Hong
Published: October 2020

Primary thyroid lymphoma (PTL) is a rare disease which responds well to rituximab-based chemotherapy. Here, we describe a case who was diagnosed through core needle biopsy as having diffuse large B-cell lymphoma in the right lobe of thyroid gland. Positron emission tomography computed tomography (PET-CT) revealed no other foci of hot spots, so PTL was considered. She was treated with rituximab plus bendamustine for three cycles, and color Doppler ultrasound revealed significant reduction of blood flow signals in the tumor but no significant decrease of its size (<25% extent). Then, the chemotherapy regimen was adjusted to rituximab, cyclophosphamide, vincristine, prednisone (R–COP), and complete remission was noted on ultrasound and PET-CT after three cycles of R–COP treatment. This case is reported to tell that color Doppler ultrasound, in addition to PET-CT, is useful to evaluate chemotherapeutic effect on PTLs.

Published: October 2020

Secretory carcinoma of the breast is a rare subtype of breast cancer. It can occur at any age but is usually diagnosed in patients under 30 years. It is the most common subtype of breast malignancy in the pediatric population and has a favorable outcome. Surgical excision is the best treatment and adjuvant therapies are still under debate. We present the case report of a 26-year-old patient with secretory carcinoma of the breast, including imaging, histologic findings, and clinical outcome.
Utility of Ultrasound Strain Elastography to Differentiate Benign from Malignant Lesions of the Breast
Authors: Kanagaraju Vikrant , Dhivya B. , Devanand B. , Maheswaran V.
Published: October 2020

Background:

The purpose of this study was to determine the utility and diagnostic performance of strain elastography (SE) in differentiating benign from malignant lesions of the breast.

Methods:

In this prospective study, 50 palpable breast masses in 50 patients were examined by mammography, B-mode ultrasound (US) and SE. Lesions were categorized using Breast Imaging Reporting and Data System (BIRADS) scoring based on mammographic and sonographic features. Elasticity scores were assessed on a five-point scale based on the distribution of strain, and the lesion size on SE imaging and B-mode (elasticity imaging/B mode [EI/B] ratio) was compared. Findings were correlated with the BIRADS assessment and diagnostic performance of sonoelastography was evaluated taking histopathology as reference standard.

Results:

Histopathology revealed 29 (58%) malignant and 21 (42%) benign lesions. Infiltrative ductal carcinoma and fibroadenoma were the most common malignant and benign lesions, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of SE was 100%, 76.1%, 85.2%, 100%, and 90%, respectively. Higher elasticity score was significantly associated with malignant histopathology (P < 0.00001). The mean EI/B ratio for malignant lesions was 1.36 ± 0.24 while that of benign lesions was 1.03 ± 0.30 (P = 0.000).

Conclusion:

Real-time SE of the breast, with its superior sensitivity and specificity, could provide improved characterization of benign and malignant breast masses compared with mammography and conventional US. Due to greater diagnostic accuracy, SE can be an effective adjunctive tool to B-mode US in predicting malignancy of breast, as well as in reducing the need for biopsies in benign breast lesions.
Echotexture Analysis of L4 Supraspinous Enthesis in Ankylosing Spondylitis
Authors: Lai Kuo-Lung , Kuo Fang-Chuan , Tseng Chih-Wei , Chen Hsin-Hua , Liao Yin-Yin
Published: October 2020

Background:

Enthesopathy is a main characteristic of ankylosing spondylitis (AS). However, ultrasonographic features of supraspinous enthesis in AS have not yet been reported.

Methods:

Forty-seven AS patients and 22 healthy individuals were enrolled and completed the study. L4 supraspinous entheses were assessed through an ultrasound (US) unit with the participants in a lateral decubitus position. Entheseal echogenicity was interpreted upon inspection of the US image. An entheseal grayscale (GS) value determination, along with an echotexture analysis using a gray-level co-occurrence matrix algorithm, was performed. The thoracolumbar fascia just above the enthesis was also analyzed. An enthesis-to-fascia ratio (EFR) of each texture feature was used for the purpose of intergroup comparison.

Results:

The prevalence of abnormal entheseal echogenicity in the AS and healthy groups was 19.1% and 13.6%, respectively (P = 0.42). The AS group experienced a higher GS EFR (0.56 [0.10–1.08] vs. 0.40 [0.12–0.89], P = 0.007), higher contrast EFR (0.62 [0.15–1.23] vs. 0.49 [0.23–1.33], P = 0.049), higher variance EFR (0.44 [0.06–1.21] vs. 0.35 [0.13–1.10], P = 0.023), and lower homogeneity EFR (1.07 [0.97–1.27] vs. 1.11 [1.04–1.19], P = 0.011) in comparison to the healthy group.

Conclusion:

Echotexture analysis identified the subtle structural changes in L4 supraspinous enthesis in AS patients. It proved to be superior to the inspection method and may possess the potential for providing early detection of supraspinous enthesopathy in AS.
Ultrasonographic Measurements of the Liver, Gallbladder Wall Thickness, Inferior Vena Cava, Portal Vein and Pancreas in an Urban Region, Malaysia
Authors: Khammas Abdul Sattar Arif , Mahmud Rozi
Published: October 2020

Background:

Ultrasonographic (USG) measurements of the liver length, gallbladder wall thickness (GBWT), diameters of the inferior vena cava (IVC), portal vein (PV), and pancreas are valuable and reliable in diagnosis hepatobiliary and pancreas conditions. This study is aimed to determine the normal values of liver length, GBWT, AP diameters of the IVC and PV, AP diameter of the head and body of the pancreas.

Methods:

A prospective cross–sectional study was carried out in this study. A total of the 408 participants were randomly recruited using a systematic method. According to the USG reports, the subjects who had normal USG report for liver, biliary system, and pancreas were described as normals, whereas the subjects who had hepatobiliary diseases such as fatty liver, liver cysts, hemangioma, cirrhosis, gallbladder wall thickening, acute cholecystitis, gallstones, and polyps were recorded as abnormal subjects.

Results:

Of the 408 participants with a mean of 52.6 ± 8.4 years old. Of those, 294 (72.1%) participants were normal and 114 (27.9%) subjects were reported as abnormal. More than half of the study population was males, 52.9% versus 47.1% of females. There was a significant difference of liver length, head, and body of the pancreas between genders (P = 0.004, 0.002, and P < 0.001, respectively). Moreover, the pancreatic body only was significantly correlated with age (P = 0.026). There also was a significant difference of the liver length, head, and body of the pancreas between normal and abnormal subjects (P < 0.001, P = 0.007, and P < 0.001).

Conclusion:

Liver length, diameter of the head, and body of the pancreas were significantly associated with gender and hepatobiliary diseases. In addition, only the diameter of the body of the pancreas was significantly correlated with age.

Authors: Lin Li-Chan , Cheng Yueh-Chin , Chang Chiung-Hsin
Published: October 2020

We describe a case of fetal congenital mesoblastic nephroma (CMN) who was diagnosed with ultrasound at 32 weeks of gestation; after delivery, the neonate received left radical nephrectomy, and pathology report confirmed the diagnosis. All cross-sectional imaging studies, such as ultrasonography, computed tomography (CT) scanning, and magnetic resonance imaging, may help to define the organ of origin and the relationship to the ipsilateral kidney. To our knowledge, this is the first case of fetal CMN who was diagnosed in the third trimester and then with a live-born baby in Taiwan. The prenatal examination such as three-dimensional ultrasound and CT image was performed to help us for prenatal diagnosis.

Published: October 2020

Radiopharmaceutical injection is challenging as it poses radiation exposure to staff as well as patient. Infrared light-assisted devices have been available since many years and have garnered mixed reviews in the pediatric age group. However, there are no data on outcome of infrared assistance for radiopharmaceutical injection. We compared results of first-attempt intravenous access (in cubital veins) with and without infrared assistance device for injection of radiopharmaceuticals. All adult patients who underwent nuclear scan in the initial weeks of infrared device installation were injected utilizing infrared device assistance. These were compared with those who underwent injection without infrared assistance. Three hundred consecutive patients were studied for success of intravenous injection with and without infrared assistance. Of these, 150 were injected with and 150 without infrared assistance. A success rate of 72%/51.3% was noted with and without infrared assistance, respectively, on the first attempt which was statistically significant. In our initial experience, assistance with infrared device was found to improve the outcome of first-attempt intravenous access for injection of radiopharmaceuticals. This method has potential of improving outcome for radiopharmaceutical injection.

What scientific information on non-structural elements seismic risk people need to know ? Part 2: tools for risk communication
Authors: Solarino Stefano , Amaral Ferreira Monica , Musacchio Gemma , Rupakhety Rajesh , O’Neill Hugo , Falsaperla Susanna , Marta Vicente , Lopes Mario , Sousa Oliveira Carlos
Published: October 2020

The present paper describes the process of moving from a research study of most common vulnerable non-structural elements, to deliver solutions, tools and guidelines to improve understanding of and responsiveness to community concerns about seismic risk and non-structural elements. The observed damage to non-structural elements following recent earthquakes in Italy, Portugal and Iceland, were used for designing communication tools under the KnowRISK EU project for multi-stakeholders (students, business and citizens): the Practical Guide, the Students Short Guide, the KnowRISK Portfolio of Solutions, the Move, Protect and Secure video, the augmented reality apps, the maquettes, the students notebooks, videos, board games and hands-on tools. The philosophy behind these deliverables is that some risks, once identified, can be eliminated or reduced by informing people and suggesting preventive or emergency measures. These tools are devoted to improving the seismic performance of non-structural elements and to reduce the associated economic losses, loss of functionality, and potential threats to life safety. The rationale behind the selection of the information that people need to know for converting knowledge to more safety is discussed and a description of the transference of the findings of research to communication solutions is presented. The tools were planned following the engagement-model in risk communication to ensure that needs of communities and selected stakeholders were acknowledged, and that recipients are addressed in a way that appeals to them. Different media and communication channels such as print, television, online, face-to face communication and interviews were used for risk communication.
A Primary Care Provider’s Guide to Wheelchair Prescription for Persons With Spinal Cord Injury
Authors: Michael Erin , Sytsma Terin , Cowan Rachel E.
Published: October 2020

The wheelchair is an essential tool for individuals with spinal cord injury (SCI). When the capacity and fit of a wheelchair is matched to the needs and abilities of an individual with SCI, health, function, community participation, and quality of life are maximized. Throughout an individual’s life, function and health status can decline (or improve), necessitating a new wheelchair and/or seating components (eg, cushions and backrests). Additionally, a patient’s current wheelchair may be identified as a factor contributing to a health concern or functional deficit, again necessitating wheelchair adjustments. Primary care physicians often manage the complex and lifelong medical needs of individuals with SCI and play a key role in wheelchair evaluation and prescription. This article provides a broad overview of indicators that a new wheelchair is needed, describes the wheelchair prescription process, identifies important team members, reviews the major wheelchair components, and provides guidance to match components to patients’ needs and abilities.
A Primary Care Provider’s Guide to Social Justice, the Right to Care, and the Barriers to Access After Spinal Cord Injury
Authors: Kuemmel Angela , Basile Josh , Bryden Anne , Ndukwe Ngozi , Simoneaux Kelley Brooks
Published: October 2020

People living with spinal cord injury (SCI) face numerous barriers to primary care. This article identifies these barriers as social justice issues to emphasize their significance and the inequality of primary care received by people with SCI. Primary care providers have a responsibility to provide equal and accessible care to all patients and to remediate any obstacles to care. Understanding the well-documented barriers of competence, physical, policy and procedural, communication, and attitudes impacting primary care for people with SCI will bring much-needed awareness and opportunity for meaningful change. This article is a call to action for social justice within primary care and provides helpful recommendations for removing and addressing barriers. Better health care outcomes for people with SCI are possible if primary care physicians and providers become social justice advocates for their patients with SCI.

DIGESTIBILIDAD DE LA MATERIA SECA DE HENO DE MANÍ RIZOMA PERENNE (A GLABRATA) COSECHADO EN EL TRÃ"PICO CARIBEÃ‘O
Authors: Teodoro M. Ruiz
Published: October 2020

La digestibilidad verdadera de la materia seca in vitro (DVMSIV) del maní rizoma perenne (MRP) fue evaluada en Lajas (núm. Pl 276233, 262826, 262833, 262839 y los cvs Florigraze y Arbrook) y Juana Díaz (núm. PI 276233, 262839 y el cv Florigraze). En ambas localidades, el forraje se cortó a intervalos de seis, nueve y 12 semanas en cada una de las cuatro estaciones del año. La DVMSIV del forraje no fue afectada por el genotipo del MRP evaluado. Las medias fueron 64.3 y 62.5% para los MRP evaluados en Lajas y Juana Díaz, respectivamente. A medida que se alargó el intervalo de corte de seis a 12 semanas la DVMSIV se redujo (P < 0.01) en una forma cuadrática. En ambos estudios, la digestibilidad del forraje cosechado a las seis y nueve semanas fue similar; al aumentar de nueve a 12 semanas hubo una reducción relativa en la DVMSIV de 6.6 y 10.6% en Lajas y Juana Díaz, respectivamente. La estación de crecimiento afectó (P < 0.01) la DVMSIV. El forraje cosechado durante el verano tuvo la digestibilidad más alta en ambas localidades. El efecto de la estación de crecimiento fue mayor en el forraje cosechado a un intervalo de 12 semanas y menor en el forraje cosechado a las seis semanas de crecimiento. La alta digestibilidad de los genotipos evaluados sugiere que el MRP es una alternativa viable para la producción de heno de alta calidad en el trópico caribeño.

La producción de forraje puede variar substancialmente durante el ciclo anual en las islas tropicales de Puerto Rico y Santa Cruz. Se ha hipotetizado que las temperaturas frías, los bajos niveles de radiación solar, y la baja precipitación en diciembre y enero son los causantes de las disminuciones en el crecimiento del forraje. Para examinar cuantitativamente estas hipótesis se utilizó un modelo de crecimiento en forraje para simular el rendimiento bajo diferentes ambientes. Los datos climáticos por un periodo de tres a seis años se obtuvieron para tres localidades en Puerto Rico y una localidad en Santa Cruz. Las temperaturas mínimas estuvieron siempre cerca o por encima de los 20°C; por lo tanto, no parecieron causar serias pérdidas en la producción de forraje. El modelo de forraje predijo una reducción en la producción de forraje en los meses de invierno debido a una disminución en los niveles de radiación solar; sin embargo, los rendimientos estimados fueron un 70 a 80% de los rendimientos del verano. Si bien el enraizamiento superficial a una profundidad menor de 45 cm podría causar disminución de los rendimientos en algunas situaciones, la precipitación inadecuada no podría explicar las grandes disminuciones ocurridas en los meses de invierno. Esta investigación indica que un factor adicional a los evaluados contribuye a la pérdida en el rendimiento del forraje durante el invierno. Se especula que la corta duración del día influye directamente sobre la regulación del crecimiento de la planta de forma tal que el rendimiento de forraje disminuye en los meses de invierno.
Crecimiento y absorción de nutrientes en mangostín crecido bajo niveles de sombra
Authors: Ricardo Goenaga  , Edmundo Rivera
Published: October 2020

El mangostín es una fruta tropical con gran potencial económico. Sin embargo, su producción comercial es limitada debido al largo período juvenil que necesita antes de producir frutas por primera vez. Hay muy poca información sobre las mejores prácticas agronómicas para acelerar el crecimiento y desarrollo de plántulas de mangostín. Se establecieron dos experimentos de 22 meses de duración cada uno para determinar el efecto de varios niveles de sombra artificial y fertilización en el crecimiento de plántulas de mangostín. Las plántulas fueron crecidas bajo 0,30,50,70 y 90% sombra y recibieron 3,6 y 9 g por tiesto de un abono comercial con análisis 15-4.8-10.8% (N-P-K) a los tres, ocho y 15 meses después de la siembra. Las plántulas crecidas bajo 50% de sombra y fertilizadas con 9 g de abono acumularon una cantidad significativamente mayor de materia seca, desarrollaron tallos más gruesos y crecieron más altas que las plántulas con los otros tratamientos. Plantas crecidas a pleno sol apenas se desarrollaron o murieron.

Se estudió el desarrollo de Tibraca obscurata Bergroth y T. limbativentris Stal en arroz en el suroeste de Colombia. Tibraca limbativentris requirió mayor tiempo para completar su desarrollo que T. obscurata. Las hembras de T. limbativentris requirieron más tiempo para completar su desarrollo que los machos, pero el desarrollo de T. obscurata fue similar en los dos sexos. Las hembras de T. limbativentris son más longevas que los machos. Tibraca limbativentris depositó aproximadamente 200 huevos en un periodo de 86 días. El tiempo de incubación de los huevos fue igual para los dos sexos (6.5 d).
Anatomía patológica de la base de la raíz pivotante y los tallos de alfalfa afectada con pudrición de la corona inducida por Phoma medicaginis Malbr. & Roum. var. medicaginis Boerema
Authors: Rocío del P. Rodríguez
Published: October 2020

La necrosis interna de la base de la raíz pivotante y de los tallos es un síntoma común asociado a la pudrición de la corona de alfalfa por Phoma. Los tejidos necrosados se examinaron utilizando técnicas histológicas e histoquímicas en preparaciones permanentes y semipermanentes. La necrosis ocurrió solamente en los tejidos leñosos afectando los elementos vasculares, fibras y el parénquima de los rayos. En la base de la raíz pivotante los tejidos del centro de la estela estaban completamente degradados y algunas células de parénquima mostraron hiperplasia. Se observó oclusión con goma y peetina en los elementos del xilema secundario. Las áreas infectadas estuvieron rodeadas de peridermo de herida limitando la colonización radial del patógeno pero no la longitudinal. Se observaron diferentes tipos de oclusión en los tallos posiblemente de la misma composición a la encontrada en la base de la raíz pivotante. Se observaron hifas dentro de los elementos traqueales.

Published: October 2020

Se evaluó el uso de productos de papel reciclado como material para carnada de pollos parrilleros y sus efectos sobre el crecimiento, desempeño productivo y lesiones en las patas. Se criaron 168 pollos parrilleros hasta la edad de mercado (42 d) en un galpón con laterales abiertos localizado en la Granja Experimental para Animales Pequeños de la Estación Experimental Agrícola de Lajas. Las aves se asignaron a 12 jaulas de piso con carnada de cascarilla de arroz (CDA) como control; una mezcla 50:50 de CDA y papel blanco triturado (PBT); o una mezcla 50:50 de CDA y papel de periódico triturado (PPT) en un diseño completamente aleatorizado repetido cuatro veces. Se evaluó el peso corporal, consumo de alimento, conversión alimenticia, rendimiento de la canal, laceraciones de la pechuga, quemadura del cojín de la pata y la mortalidad. El porcentaje de humedad de la carnada se determinó a los 14, 28 y 42 d de edad. El material utilizado como carnada no afectó el peso corporal, consumo de alimento, laceraciones de la pechuga ni la mortalidad de las aves. Sin embargo, los pollos criados en PBT mostraron un menor consumo de alimento y un mayor peso corporal al compararse con aquellos criados en CDA y PPT. No se observaron diferencias significativas en la conversión de alimento de los siete a los 28 d de edad. A los 35 y 42 d, los pollos criados en PBT mostraron una menor conversión de alimento que las aves criadas en CDA, mientras que la conversión de alimento de los pollos criados en PPT fue similar a la de los demás tratamientos. No se encontraron diferencias en el rendimiento de la canal entre los tratamientos estudiados. En todos los periodos de muestreo, el porcentaje de humedad de la carnada fue significativamente mayor en PPT que en las demás carnadas. No se observaron problemas de áreas húmedas en ninguna de las carnadas estudiadas. Se observaron diferencias significativas en quemaduras del cojín de las patas, siendo la incidencia mayor en los pollos criados en PPT, menor en CDA e intermedia en aquellos criados en PBT. Los resultados sugieren que los productos de papel reciclado pueden ser una excelente alternativa como material de carnada para el levante de pollos parrilleros. La utilización de PBT aparenta mejorar el desempeño productivo y reducir la incidencia de quemaduras del cojín de las patas.
Subproductos vegetales como fuente de fibra para vacas lactantes consumiendo dietas bajas en forraje.

Se evaluó la efectividad de la fibra en la semilla de algodón entera (SA), salvado de trigo (ST) y la cascarilla de arroz en vacas Holstein en lactancia temprana (30 a 50 días) recibiendo dietas mezcladas bajas en fibra detergente neutra (FDN). Los tratamientos experimentales evaluados fueron (T1) control, dieta formulada para 25% FDN con 19% FDN provisto por heno picado (FDNH); (T2) dieta formulada para 35% FDN con 19% FDNH y el exceso de FDN provisto por la mezcla de SA, AT, y cascarilla de arroz en el concentrado; (T3) dieta formulada para 25% FDN con 10% FDNH y el remanente provisto por la mezcla de los tres subproductos en el concentrado. Todas las vacas se alimentaron con heno de alfalfa al 6% del consumo total de MS y con heno de yerba pangóla hasta alcanzar el FDNH deseado. Las diferencias entre los tratamientos no fueron estadísticamente significativas (P > 0.05) para consumo de MS (18.3 kg/d), consumo a base de peso vivo (3.22%), producción de leche (32.7 kg/d) y concentración de proteína láctea (2.65%). El reducir la concentración de FDNH a 10% (T3) resultó en una reducción relativa en la concentración de grasa láctea de un 15% (P < 0.01) comparado a la alimentación con 19% FDNH (T1 yT2). Aún cuando la dieta T3 resultó en un mayor consumo de energía para la producción de leche (NEL), la eficiencia energética en la producción de leche (Mcal-leche/Mcal-alimento) resultó aproximadamente 15% menor que al consumir las dietas con 19% FDNH (T1 yT2). La fibra adicional en la mezcla de subproductos en el concentrado (T2) no fue efectiva en promover o en aumentar la grasa láctea y tampoco pudo evitar una reducción en la grasa por debajo de 3.0% cuando se redujo la FDNH (T3). Por consiguiente, la FDN en la mezcla de subproductos no demostró ser de efectividad ruminal bajo las condiciones de este experimento.
