Undescended testis: timing of referral and surgical intervention, Urology Center, Benghazi, Libya
Authors: Tarhoni O , Etabbal A , Trkawi A
Published: February 2018

Background: Undescended testis (UDT) is the failure of testes to descend into the scrotum. It is classified according to the site of arrest into; Intra-abdominal, deep inguinal ring, canalicular, or emergent from the superficial inguinal ring. The diagnosis of UDT is mainly clinical and its treatment is usually surgical. The aim of our study is to analyze age distribution at the time of diagnosis and treatment to determine if the international guideline recommendations are followed in our institution or not.

PATIENTS & METHODS: A retrospective study was carried at Urological Center by reviewing the files of 75 consecutive patients admitted to the hospital in the period from July 2011 to April 2014. A data flow sheet was used to record and analyze the patients' personal data, age at diagnosis, physical findings, type of surgical procedure, and the age of the patients at the time of surgery, as well as surgical findings.

Results: Total number of patients enrolled in the study was 75 patients. Fifty-two cases were diagnosed at birth, 14 cases discovered incidentally, and 9 cases were presented with reducible inguinal swelling with or without pain. The 75 patients had 93 UDTs, 49 UDTs on right side and 44 UDTs on left side. Sixty-nine UDTs were clinically palpable while the other 24 UDTs were not palpable (74.2% and 25.8% respectively). The mean age at the time of diagnosis was 3.7 ± 8.3 years. However, the mean age at the time of surgery was 10.8 ± 10 years. The surgical procedures performed were: orchiopexy (n=58, 62.3 %,), orchiopexy combined with ipsilateral hernial repair (n=16, 17.2%) and orchiectomy (n=19, 20.4%).

Conclusion: In our institution, the mean age at orchiopexy was significantly delayed beyond the recommended time of surgery because of delayed diagnosis or referral.

Published: February 2018

Green roof is a low impact development (LID) practice used to mitigate imperviousness in urban areas and to reduce flood risks. In order to have sufficient designs and accurate runoff predictions, computer models should be utilized with full understanding of green roofs' hydrologic processes. Evapotranspiration is usually considered important by researchers in the water balance modeling of a green roof. The Storm Water Management Model (SWMM) version 5.1 is widely utilized rainfall-runoff modeling software which has LID controls capable of modeling green roofs. A previous study has evaluated the performance of this model in green roof simulations for single events without considering evapotranspiration in its application, but attained negative outcomes. Thus, the objective of this study is to determine the significance of considering evapotranspiration in producing accurate runoff simulations specifically using SWMM 5.1. The results of this study have shown that when evapotranspiration was not considered, simulations failed to agree with observed values, whereas when evapotranspiration was considered, simulated runoff volumes attained a very good fit with the observed runoff volumes proving the significance of evapotranspiration as an important parameter in green roof modeling.

Published: February 2018

Long-standing wastewater and reclaimed water irrigation systems degrade groundwater quality and thus pose great risks to local soils and even to human health. In this study, seasonal variations in hydrochemical characteristics of groundwater were assessed to determine possible processes that induce groundwater degradation. Beijing was used as the focus area. A total of 82 wells at the southeast irrigation region of Beijing were investigated in 2014. Descriptive statistics, correlation analysis, Piper diagram, and saturation indices were used to distinguish seasonal variations in hydrochemistry in shallow and deep groundwater and possible reclaimed water irrigation effects. The main natural controlling processes include mineral precipitation and dissolution, cation exchange reactions, and dilution effects in shallow and deep groundwater. However, cation exchange reactions are considered to be intense in deeper aquifer. Additionally, shallow groundwater sites subjected to salinization and nitrate contamination were associated with intensive agricultural input and reclaimed water leaching. Sites continuously contaminated by nitrate were mainly distributed on highly permeable sediments. Irrigation with deep groundwater may reduce soil drainage conditions due to a high percentage of sodium. Overall, seasonal replenishment for subterranean quaternary aquifers from rainfall or irrigation plays a vital role in seasonal variation in shallow groundwater hydrochemistry.
Modeling of extreme risk in river water quality under climate change
Authors: Rehana S. , Dhanya C. T.
Published: February 2018

A river water quality management model under average climatic conditions may not be able to account for the extreme risk of low water quality which is more prominent under an increase in river water temperature and altered river flows. A modeling framework is developed to assess the risk of river low water quality extremes by integrating a statistical downscaling model based on Canonical Correlation Analysis, risk quantification model based on Frank Archimedean Copula function and multiple logistic regression model integrated with a river water quality simulation model, QUAL2 K. The results reveal that the combination of predicted decrease in low flows of approximately 57% and increase in maximum river water temperatures of approximately 1.2°C has shown an increase of about 46% in risk of low water quality conditions for the future scenarios along Tunga-Bhadra River, India. The extreme risk of low water quality is observed to increase by 50.6% for the period 2020–2040 when compared with the current extreme conditions of 4.5% and average risk conditions of about 3% for the period 1988–2005. The study captured the occurrence of extremes of low water quality with evidence of a strong link between climate and water quality impairment events.
A mathematical hypothesis to research the effects of heat and humidity from the TGR on the local climate
Authors: Luo Qing , Zhang Hongjie , Lin Lin , Chen Min , Sun Yahong
Published: February 2018

Previous research studies focused only on data of local air temperature and humidity, ignoring the water body itself, which cannot definitively answer the question of how the Three Gorges Reservoir's (TGR) water affects the local climate overall. To understand the effect of the TGR on the local climate quantitatively, this paper provides an original mathematical hypothesis and proves in theory there is only one way to calculate the transfer of heat and humidity between the TGR and the local air. Based on this mathematical hypothesis, a detailed research method to explore the effects of the TGR's heat and humidity on local climate was formed. A field investigation was conducted and a research site was selected in Chongqing. This study has determined the effects of the TGR's heating or cooling on the air during the measuring period. A mathematical model to assess the effects of heat and humidity from the TGR on local climate was set up. The final results based on the mathematical model show that the average air temperature decreased 0.67 K and the average moisture content increased 0.25 g/kg during the 24 hours measuring time for the area studied.
Prevention and Treatment for Chemotherapy-Induced Peripheral Neuropathy: Therapies Based on CIPN Mechanisms
Authors: Hu Lang-Yue , Mi Wen-Li , Wu Gen-Cheng , Wang Yan-Qing , Mao-Ying Qi-Liang
Published: February 2018

Background:

Chemotherapy-induced peripheral neuropathy (CIPN) is a progressive,
enduring, and often irreversible adverse effect of many antineoplastic agents, among which sensory
abnormities are common and the most suffering issues. The pathogenesis of CIPN has not been
completely understood, and strategies for CIPN prevention and treatment are still open problems for
medicine.

Objectives:

The objective of this paper is to review the mechanism-based therapies against sensory
abnormities in CIPN.

Methods:

This is a literature review to describe the uncovered mechanisms underlying CIPN and to
provide a summary of mechanism-based therapies for CIPN based on the evidence from both animal
and clinical studies.

Results:

An abundance of compounds has been developed to prevent or treat CIPN by blocking ion
channels, targeting inflammatory cytokines and combating oxidative stress. Agents such as glutathione,
mangafodipir and duloxetine are expected to be effective for CIPN intervention, while
Ca/Mg infusion and venlafaxine, tricyclic antidepressants, and gabapentin display limited efficacy
for preventing and alleviating CIPN. And the utilization of erythropoietin, menthol and amifostine
needs to be cautious regarding to their side effects.

Conclusions:

Multiple drugs have been used and studied for decades, their effect against CIPN are
still controversial according to different antineoplastic agents due to the diverse manifestations
among different antineoplastic agents and complex drug-drug interactions. In addition, novel therapies
or drugs that have proven to be effective in animals require further investigation, and it will
take time to confirm their efficacy and safety.

INTRODUCTION TO SPECIAL ISSUE 4 : PLANNING MALAYSIA JOURNAL
Authors: Mohammed Osman Mariana , Rabe Noor Suzilawati
Published: February 2018

This issue of Planning Malaysia Journal includes a mixture of articles addressing various issues in contemporary urban planning. Article 1 raises the question of whether green initiatives in educational institutions, especially universities, were successful in producing green graduates. A survey among green and non-green universities students showed that there is no significant difference in the level of perception, attitude and responsible environmental behaviour between green and non-green universities graduates. Thus, it suggests that students’ involvement in universities’ green initiatives should be increased.Article 2 discusses the impacts of street urban design on the perceived safety by women respondents. As women’s role in the cities becoming more pronounced, the authors suggest that streets and urban design should consider the safety of women so that street can become a safe and highly utilised public space. Article 3 looks at the factors affecting house prices in Malaysia in order to determine the alternative benchmark for Islamic home financing scheme. It shows that house price index are influenced by economic growth, demand for housing loan and construction materials. Article 4, in the meantime, compares the Islamic home financing schemes on offer in Malaysia nowadays, and suggest that there is a need for banks to move on from the Al-Bay Bithaman Ajil to Musharakah Mutanaqisah Partnership housing financing scheme.Article 5 looks how innovative management of natural resources leads to increased participation of the local community and improved revenue for rural businesses. These, in turn, motivates local stakeholders to continue preserving the resources. Article 6 examines the practices regarding food waste management in hotels in Langkawi. It found that there was a lack of emphasis from the hotels on their policy related to wastage of food and unsustainable food consumption pattern by their guests. This reflects on the lack of practices towards sustainable food waste management by the hotel sector.Article 7 identifies changes and threats to Malay landscape preservation in traditional Malays houses in Melaka and Kelantan. It concludes that threats to such preservation include inappropriate use of garden space, problems regarding house ownership, inadequate fund for maintenance, and current development trend that leads to traditional Malay garden setting being replaced by modern setting.Article 8 discusses the use of agroforestry approach to improve sustainability of oil palm smallholdings. Rapid development and expansion of natural forest into oil palm land has decreased the agricultural sustainability of Malaysian oil palm production. However, the article shows that sustainability of oil palm smallholdings can be improved through agroforestry, which at the same time was found to also improve income of the smallholders.

Authors: Klassen Karen Michelle , Borleis Emily S , Brennan Linda , Reid Mike , McCaffrey Tracy A , Lim Megan SC
Published: February 2018

BACKGROUND

Health campaigns have struggled to gain traction with young adults using social media, even though more than 80% of young adults are using social media at least once per day. Many food industry and lifestyle brands have been successful in achieving high levels of user engagement and promoting their messages; therefore, there may be lessons to be learned by examining the successful strategies commercial brands employ.

OBJECTIVE

This study aims to identify and quantify social media strategies used by the food industry and lifestyle brands, and health promotion organizations across the social networking sites Facebook and Instagram.

METHODS

The six most engaging posts from the 10 most popular food industry and lifestyle brands and six health promotion organizations were included in this study. A coding framework was developed to categorize social media strategies, and engagement metrics were collected. Exploratory linear regression models were used to examine associations between strategies used and interactions on Facebook and Instagram.

RESULTS

Posts from Facebook (143/227, 63.0%) and Instagram (84/227, 37.0%) were included. Photos (64%) and videos (34%) were used to enhance most posts. Different strategies were most effective for Facebook and Instagram. Strategies associated with higher Facebook interactions included links to purchasable items (beta=0.81, 95% CI 0.50 to 1.13, P<.001) featuring body image messages compared with food content (beta=1.96, 95% CI 1.29 to 2.64, P<.001), and where the content induced positive emotions (beta=0.31, 95% CI 0.04 to 0.57, P=.02). Facebook interactions were negatively associated with using pop culture (beta=–0.67, 95% CI –0.99 to –0.34, P<.001), storytelling (beta=–0.86, 95% CI –1.29 to –0.43, P<.001) or visually appealing graphics (beta=–0.53, 95% CI –0.78 to –0.28, P<.001) in their posts compared with other strategies. Posting relatable content was negatively associated with interactions on Facebook (beta=–0.29, 95% CI –0.53 to –0.06, P=.01), but positively associated on Instagram (beta=0.50, 95% CI 0.05 to 0.95, P=.03). Instagram interactions were negatively associated with weight loss (beta=–1.45, 95% CI –2.69 to –0.21, P=.02) and other content (beta=–0.81, 95% CI –1.57 to –.06, P=.04) compared with food content.

CONCLUSIONS

Health promotion professionals and organizations can improve engagement using positive messaging and tailoring posts appropriate for different social media channels.

Published: February 2018

Aluminum and steel are used to be a construction for a building outdoor panel. Aluminum and steel are connected by bolt and nut. An atmosphere due to a corrosion of the aluminum. The corrosion possibly to cause the hole diameter of bolt and nut to become larger. Thus the bolt and nut can not enough strong to hold the panel. The panel may collapse. The aim of the research is first to answer a question where does the corrosion starts. The second is to know the effect of ratio surface area of steel with aluminum on the corrosion rate of aluminum. The research is started to cut a steel and aluminum flat into variation surface areas. Next, the steel and aluminum are bolted as samples for corrosion test. The samples are divided into two groups. The group A was immersed in NaCl (10%) and the groups B was immersed in HCl 10%. The corrosion rate is calculated with loss weight method. The conclusions are as follow. The corrosion does not start from the bolt hole but from the edge of aluminum. Increasing the ratio of surface area (steel/aluminum) increases the corrosion rate of aluminum.

Published: February 2018

Non-destructive testing is a wide group of analysis techniques used in science and industry to evaluate the properties of a structure without causing damage to it. The main objective of this project is to carry out experiment to detect leakage in pipeline using nonlinear acoustic modulation method. The nonlinear acoustic modulation approach with low frequency excitation and high frequency acoustic wave is used to reveal modulations in the presence of leak. The pipe used in this experiment was galvanized iron pipe. The experiment is started with the experiment of undamaged specimen and followed by the experiment of damaged specimen with manually applied leak. The results obtained are being observed and the difference between the specimen without leak and with leak can be distinguished. The distance of the leak and the distance of the outlet detected is nearly accurate to the exact location which is leak at 4.0 m and outlet at 6.0 m. Therefore, the results demonstrate that leakage can be detected using nonlinear acoustic modulation, and proved the objective of distinguish the difference between the results of specimen without leak and with leak has succeeded. The damage detection process can be eased with the knowledge on the signal features.

Published: February 2018

In this paper, we present a bandpass filter that passed frequency of 1.7 GHz – 1.8 GHz. It is applied for an uplink frequency in 4G 1800MHz. This filter is created by using substrate PCB TMM-10i and has a compact size of 42 mm x 42 mm. The compact size is also important besides selectivity. The selectivity is achieved by implementing cascade square loop resonator method which generated transmission zeros. Actually, transmission zeros are obtained from the coupled resonator. The bandpass filter is designed by adding an external resonator on each square of the resonator loop and a patch to the inside of the square loop resonator. The parameter performances are simulated by HFSS. The parameter performances for return loss value is 14.24 dB at frequency 1.75 GHz and insertion loss value is 0.65 dB at frequency 1.75 GHz. By using VNA Anritsu MS 2026A, prototype bandpass filter is measured. The measurement results for return loss value is 6.8 dB and insertion loss value is 2.2 dB.

Introdução: O uso de analgésicos opióides na dor crônica vem sendo relatado na literatura como um dos principais fármacos utilizados nessa experiência sensorial e emocional desagradável, relacionada ao dano tecidual real ou potencial, sendo sempre uma experiência subjetiva. O sistema nervoso central (SNC) é o responsável pela percepção dolorosa, que envolve estímulos nociceptivos e a reação emocional. A dor crônica pode estar relacionada a pacientes oncológicos prolongados, portadores de doenças como: câncer de mama, ovário, próstata, pulmão, mielomas múltiplos, entre outros que envolvem o comprometimento funcional e a qualidade de vida do paciente. Os principais usos terapêuticos para alívio da dor incluem opioides, antidepressivos tricíclicos e anti-inflamatórios não esteroidais (AINES). Sendo os opioides considerados os analgésicos mais potentes, entre eles morfina, codeína, tramadol e oxicodona. Dentre estes é valido destacar a codeína e a morfina que são fármacos utilizados de primeira escolha para dor de intensidade leve a moderada. Metodologia: O estudo foi feito na farmácia ambulatorial do HC-UFPE, através da coleta e avaliação de dados dos processos de 195 pacientes do Programa da Dor Crônica, que pertence ao Componente Especializado da Assistência Farmacêutica do Ministério da Saúde, durante o ano de 2015.Resultados e Discussão: Do cadastro de 195 pacientes analisados, 91 utilizaram morfina e 104 codeína.

Published: February 2018

Estudos evidenciam que um percentual significativo da população sofre de estresse laboral, e um dos motivos é a adaptação ao uso das tecnologias digitais. Embora as tecnologias, estejam potencializando inúmeras transformações na forma de viver em sociedade, elas podem produzir problemas físicos e sociais na saúde dos professores. Tal situação pode levá-los a sofrer de mal-estar causado pelo uso das tecnologias digitais, denominado tecnostress. Este artigo tem como objetivo compreender a relação entre a formação docente e o tecnostress no que se refere a  utilização de tecnologias digitais em escolas públicas. Para tanto, desenvolveu-se uma pesquisa quantitativa/qualitativa através de um questionário composto por sete questões fechadas e uma aberta, realizada com 49 professores de matemática da região sul do Rio Grande do Sul. Priorizamos para este artigo a questão aberta que foi analisada pelo viés qualitativo, e utilizou-se para tal a Análise Textual Discursiva (ATD). Emergiram três categorias: Interesse dos Alunos e Potencialidades das Tecnologias da Informação e Comunicação - TIC; Formação docente; e Infraestrutura. Neste estudo será analisada a categoria Formação do Professor, considerando-se o crescente acesso a tecnologias digitais, a demanda social presente nos espaços escolares e a importância da formação inicial e continuada que atendam à realidade. Observou-se que as tecnologias são importantes potencializadoras nos processos educacionais, porém a falta formação que aborde o uso das tecnologias de forma pedagógica, causa sentimentos de mal-estar nos docentes - o tecnostress. Para minimizar esses efeitos é necessário investir em formações condizentes com a realidade tecnológica vivida pelos alunos.

A educação nos anos iniciais do Ensino Fundamental, na educação infantil e na educação de jovens e adultos no Brasil acontece, quase que majoritariamente, pela atuação do profissional pedagogo. Dessa forma, tal profissional precisa aventura-se também pelo Ensino de Ciências. Sabendo que muitas vezes os cursos de Pedagogia oferecem poucas disciplinas acerca de fundamentos e metodologias dentro do tema, os cursos de extensão ainda na formação inicial desses profissionais podem ser muitos positivos para sua prática. Nesse contexto, o presente trabalho faz um relato sobre um curso de extensão oferecido para pedagogos em formação, no intuito de fornecer possibilidades para um ensino de ciências contextualizado. Objetivamos discutir e refletir acerca da necessária aproximação dos conteúdos científicos com cotidiano dos estudantes através da articulação do conhecimento científico com, no caso, a cultura. O tema do curso foi sobre culturas alimentares e sua articulação com alguns dos processos envolvidos no ato de alimentar-se e nutrir-se. A intenção de trabalhar ciências de forma contextualizada é para romper com o ensino transmissivo, que não foca na reflexão e na utilidade desse conhecimento na vida dos estudantes.

Cypermethrin is a large spectrum action insecticide, globally employed to control pests in agriculture and some human and domestic animals ectoparasites. This study aimed to evaluate its toxicity and reproduction impairment in male guinea pig. Forty adult male guinea pigs were divided into 4 groups and orally submitted to 0, 92, 137.5 and 275 mg/kg body weight/day for 90 days. The weight of the liver increased significantly, while that of kidneys decreased significantly in treated animals compared to controls. Serum concentrations of creatinine, urea, ALAT, ASAT, total cholesterol, prostatic acid phosphatase increased significantly, while the testicular total protein level decreased significantly in groups given the insecticide relatively to the control. The testes weight, libido, serum level of testosterone, mobility, sperm count and the percentage of spermatozoa with entire plasma membrane decreased significantly in animals exposed to cypermethrin with reference to controls. The percentages of abnormal spermatozoa increased significantly in animals submitted to 137.5 or 275 mg/kg body weight (bw) of cypermethrin compared to control ones. On the testis histological sections of pesticide-treated animals, immature germinal cells were observed in the lumen of seminiferous tubules. Cypermethrin was toxic in male guinea pig and damaged reproductive parameters.

Akar kuning merupakan salah satu tumbuhan obat asli Kalimantan yang terdiri dari sedikitnya tiga spesies yaitu Fibraurea tinctoria Lour., Arcangelisia flava Merr. dan Coscinium fenestratum (Gaertn.) Colebr. Bagian batang dan akar dari tumbuhan ini dimanfaatkan secara tradisional oleh etnis asli Kalimantan seperti Dayak dan Banjar serta Kutai untuk mengobati beberapa penyakit seperti malaria, hepatitis/liver dan kencing manis. Khasiat tersebut didukung oleh berbagai penelitian yang menyebutkan akar kuning mengandung senyawa kimia yang berperan sebagai hepatoprotektor, antibakteri, anti malaria dan anti kanker. Jenis Coscinium fenestratum memiliki nilai komersial tinggi di India dan Srilangka sebagai bahan baku industri obat modern. Perdagangannya di negara tersebut telah diatur sangat ketat karena berimbas pada kelangkaan jenis tersebut akibat eksploitasi besar-besaran. Meskipun akar kuning memiliki potensi besar sebagai bahan baku industri obat modern, namun saat ini informasi perdagangan akar kuning di Indonesia masih sangat terbatas. Kajian ini dilakukan untuk mengumpulkan informasi perdagangan akar kuning di sejumlah pasar tradisional di Kalimantan Selatan. Informasi dasar ini diharapkan dapat menjadi pertimbangan dalam menentukan strategi pengembangan dan pemanfaatan akar kuning sebagai komoditas Hasil Hutan Bukan Kayu (HHBK). Berdasarkan pengumpulan data di lapangan, kebutuhan akar kuning untuk industri jamu tradisional di Kalimantan Selatan masih relatif sedikit. Ketersediaan akar kuning masih memadai dan belum terjadi eksploitasi besar-besaran di alam untuk pasokan akar kuning di wilayah Kalimantan Selatan.

El síndrome hemofagocítico, considerado como una entidad poco frecuente, de etiología multifactorial, y cuya presentación es la de un cuadro grave y de alta letalidad, ofrece dificultades en la aproximación diagnostica temprana. Se presenta el caso de un niño de 26 meses de edad, con síndrome febril prolongado asociado a pancitopenia y visceromegalias (hepatoesplenomegalia) rápidamente crecientes en el curso de la evolución. Durante la hospitalización requiere varias transfusiones de hemoderivados sin mejoría. Se descartan enfermedades infecciosas como toxoplasmosis, citomegalovirus, SIDA, hepatitis B y sífilis, al igual que etiología linfo y mieloproliferativa. Se usan herramientas de laboratorio que orientan el diagnóstico a linfohistiocitosis hemofagocitica secundaría a infección por Virus Epstein-Barr, y recibe tratamiento con Inmunoglobulina y esteroides con evolución satisfactoria. Es importante considerar dentro de las causas de síndrome febril prolongado, patologías como la linfohistiocitosis hemofagocítica, secundaria a agentes comunes en nuestro medio como el Epstein Barr virus.

Objetivo: Determinar la frecuencia del consumo de alcohol y caracterizar las variables relacionadas con el consumo entre estudiantes de los programas presenciales de medicina y enfermería de la Universidad Surcolombiana. Métodos: Estudio descriptivo transversal y prospectivo durante el año académico 2012. La totalidad de estudiantes encuestados fue 413, quienes respondieron un cuestionario de auto reporte que incluyó el test para identificación de trastornos relacionados con alcohol(AUDIT) y otras preguntas adicionales. Se realizó análisis univariado y bivariado, utilizando el programa Microsoft Office Excel 2007 y EPI Info 7. Resultados: Del total de la población, 53% eran hombres, siendo este el grupo de mayor consumo de bebidas alcohólicas, con un riesgo mayor (OR 4.7, chi 11.57, p 0.0006) sobre el género femenino, de igual forma al comparar el consumo de los estudiantes de medicina sobre los de enfermería, fuede 80%, y 20% respectivamente ((OR 3,26 Chi 7,04 p 0,0079)). La edad en relación al riesgo alto de consumo se encuentra en mayor proporción en mayores de 20 años de edad, considerándose un riesgo bajo para la mayoría de los encuestados (OR 1,09 Chi 0,05 p 0,819). Conclusiones: Pertenecer al género masculino evidencia un riesgo mayor de consumo de bebidas alcohólicas, al igual que ser estudiante de medicina en comparación con enfermería, determina un riesgo mayor para tener trastornos asociados al consumo de alcohol, por el contrario la edad no reporto ser un factor de riesgo alto para desarrollar estos trastornos.
