Mitral Stenosis in Pregnancy: A Comprehensive Review of a Challenging Cardio-Obstetric Clinical Entity
Authors: Abdelrahman Safinaz , Yousif Nooraldaem 
Published: February 2019

Background:Mitral stenosis is one of the most commonly encountered valvular heart diseases during pregnancy, the majority are rheumatic in origin and poorly tolerated due to cardiocirculatory changes that occur during pregnancy, labor and postpartum.Objective:The distinctive physiological events that arise during pregnancy and labor and the influence of mitral stenosis are tackled in this article.Methods:Through PUBMED and MEDLINE searches, we reviewed the literature of the last decade as well as the recommendations from guidelines of high-impact worldwide.Results:Cardiac decompensation usually takes place late in pregnancy as the hemodynamic burden of pregnancy become more pronounced as well as after delivery due to an abrupt increase of preload secondary to autotransfusion and aorto-caval decompression. The maternal and fetal complications correlate with the New York Heart Association (NYHA) functional classification and the grade of mitral stenosis. Medical therapy should be tried first. If symptoms continue in spite of optimal medical therapy, invasive procedures are recommended. Several studies revealed that vaginal delivery under epidural anesthesia is endurable and of low-risk unless obstetrically contraindicated.Conclusion:Pregnancy and mitral stenosis remain a complex entity and a well-known trigger of maternal mortality during pregnancy and peri-partum period if not managed adequately. A good appreciation and recognition of the physiology of pregnancy and its impact on the pre-existing mitral stenosis and the presence of a specialized multidisciplinary team to handle such cases significantly decrease maternal and fetal mortality and morbidity.

Published: February 2019

Background:

Staphylococcus aureus is a leading cause of food poisoning resulting from the consumption of contaminated food with staphylococcal enterotoxins. Raw meat is a good medium for the survival and spread of drug-resistant S. aureus.

Objective:
To look for the prevalence of drug-resistant S. aureus in Addis Ababa abattoir enterprise.

Material & Methods:
A cross-sectional study was conducted from November 2013 to April 2014 in Addis Ababa abattoir enterprise. A total of 185 swab samples were collected from the carcasses of sheep, goat and slaughtering materials such as workers’ clothes, vehicles, knives and hands. Isolation and identification of S. aureus were conducted using the conventional culture methods and signatory tests. Antimicrobial sensitivity was conducted using standard methods.

Results:
The overall prevalence rate for S. aureus in the present study was 33%. The higher prevalence rates of S. aureus were recorded from sheep carcasses 36%, followed by 30% from the environment and 16% from goat carcasses. The variation in the prevalence of S. aureus between the carcasses and environment was not statically significant (p > 0.05). More than 90% of S. aureus strains were sensitive to vancomycin, chloramphenicol, gentamicin and kanamycin. While 86.9% S. aureus strains were resistant to penicillin G 80.3% resistant to ampicillin, 63.9% resistant to ceftriaxone, 62.3% resistant to oxacilin, and 62.3% resistant to cefoxitin respectively.

Conclusion:
The present study indicated that the quality of slaughtered sheep carcasses was more contaminated by S. aureus as compared to goat carcasses, during slaughtering, processing, handling and transportation. The presence of MDR strain in the carcasses demonstrates that there is a growing need to control antimicrobial resistance in sheep and goat carcasses.
SPREAD - A Routing Protocol to Meet End-to-end Adjusted Deadline in Real Time Wireless Sensor Networks
Authors: Jain Neetika , Mittal Sangeeta 
Published: February 2019

Background:
Real Time Wireless Sensor Networks (RT-WSN) have hard real time packet
delivery requirements. Due to resource constraints of sensors, these networks need to trade-off energy
and latency.

Objective:
In this paper, a routing protocol for RT-WSN named “SPREAD” has been proposed. The
underlying idea is to reserve laxity by assuming tighter packet deadline than actual. This reserved
laxity is used when no deadline-meeting next hop is available.

Objective:
As a result, if due to repeated transmissions, energy of nodes on shortest path is drained out,
then time is still left to route the packet dynamically through other path without missing the deadline.

Results:
Congestion scenarios have been addressed by dynamically assessing 1-hop delays and avoiding
traffic on congested paths.

Conclusion:
Through extensive simulations in Network Simulator NS2, it has been observed that
SPREAD algorithm not only significantly reduces miss ratio as compared to other similar protocols
but also keeps energy consumption under control. It also shows more resilience towards high data
rate and tight deadlines than existing popular protocols.
Applying Computer Vision Technology to Triaxial Deformation Monitoring of Remedial Construction for a Landslide
Authors: Chen I-Hui , Ho Shei-Chen , Chen Jun-Yang , Lin Yu-Shu , Su Miau-Bin 
Published: February 2019

Background & Objective:
The paper explores a new instrument of computer vision to
measure three-dimension deformation with an Internet of Things (IoT) system including Raspberry
Pi, digital cameras and OpenCV programs in laboratory and field testing so as to monitor the potential
deformation of a structure drainage well in a landslide.

Methods:
A chessboard pattern is detected in the image by the camera so that pixels of chessboard
cornors can be recognized by OpenCV programs. X-direction, Y-direction and Z-distance changes
can be casulated by the similar triangles relationship of camera pixels. For laboratory testing, standard
deviations of the measurement were approximately 0.01 cm.

Results:
For field testing, the study installed four sets of Raspberry Pi in a drainage well within a
landslide and employed OpenCV programs to interpret pixel changes of chessboards at four levels of
the draiage well.

Conclusion:
Overall, the instrument can be employed for triaxial deformation monitoring of the construction
in the field effectively and automatically.
STBCP: An Energy Efficient Sub-threshold Bee Colony-based Protocol for Wireless Sensor Networks
Authors: Kia Ghazaleh , Hassanzadeh Alireza 
Published: February 2019

Background & Objective:
In this paper, a new energy efficient LEACH-based protocol
for wireless sensor network is presented. One of the main issues in Wireless Sensor Networks
(WSNs) is the battery consumption. In fact, changing batteries is a time consuming task and expensive.
It is even impossible in many remote WSNs.

Methods:
The main goal of the presented protocol is to decrease the energy consumption of each
node and increase the network lifetime. Lower power consumption results in longer battery lifetime.
This protocol takes the advantage of sub-threshold technique and bee colony algorithm in order to
optimize the energy consumption of a WSN. Simulation results show that the energy consumption of
the wireless sensor network reduces by 25 percent using STBCP in comparison with recent LEACHbased
protocols. It has been shown that the average energy of the network remains balanced and the
distribution of residual energy in each round is equitable.

Conclusion:
In addition, the lifetime of a network using STBCP protocol has been increased by 23
percent regarding recently presented routing protocols.
Improved DV-Hop Localization Scheme for Randomly Deployed WSNs
Authors: Goyat Rekha , Rai Mritunjay Kumar , Kumar Gulshan , Kim Hye-Jin , Lim Se-Jung 
Published: February 2019

Background:
Wireless Sensor Networks (WSNs) is considered one of the key research area
in the recent. Various applications of WSNs need geographic location of the sensor nodes.

Objective:
Localization in WSNs plays an important role because without knowledge of sensor nodes
location the information is useless. Finding the accurate location is very crucial in Wireless Sensor
Networks. The efficiency of any localization approach is decided on the basis of accuracy and localization
error. In range-free localization approaches, the location of unknown nodes are computed by
collecting the information such as minimum hop count, hop size information from neighbors nodes.

Methods:
Although various studied have been done for computing the location of nodes but still, it is
an enduring research area. To mitigate the problems of existing algorithms, a range-free Improved
Weighted Novel DV-Hop localization algorithm is proposed. Main motive of the proposed study is
to reduced localization error with least energy consumption. Firstly, the location information of anchor
nodes is broadcasted upto M hop to decrease the energy consumption. Further, a weight factor
and correction factor are introduced which refine the hop size of anchor nodes.

Results:
The refined hop size is further utilized for localization to reduces localization error significantly.
The simulation results of the proposed algorithm are compared with other existing algorithms for
evaluating the effectiveness and the performance. The simulated results are evaluated in terms localization
error and computational cost by considering different parameters such as node density, percentage
of anchor nodes, transmission range, effect of sensing field and effect of M on localization error. Further
statistical analysis is performed on simulated results to prove the validation of proposed algorithm. A
paired T-test is applied on localization error and localization time. The results of T-test depicts that the
proposed algorithm significantly improves the localization accuracy with least energy consumption as
compared to other existing algorithms like DV-Hop, IWCDV-Hop, and IDV-Hop.

Conclusion:
From the simulated results, it is concluded that the proposed algorithm offers 36% accurate
localization than traditional DV-Hop and 21 % than IDV-Hop and 13% than IWCDV-Hop.
Michel Graulich y el problema del desfase estacional del año vago mexica
Authors: Iwaniszewski Stanislaw 
Published: February 2019

Resumen: Como se sabe, varios investigadores observaron que en el siglo XVI, el significado de los nombres de las veintenas del calendario mexica no coincide con el ciclo de las estaciones. Ya que el año vago mexica (xihuitl) de 365 días es proximadamente un cuarto día inferior al año trópico de 365.2422 días, el año mexica (xihuitl) se estaba desplazando del año trópico a un ritmo fijo. Michel Graulich (1976, 1979) supuso que la falta de la correspondencia de los nombres de los ritos y de las veintenas con las estaciones del año se debió a la firmeza de este desplazamiento, y calculando hacia atrás concluyó que fue durante el periodo de 680 a 683 e.c. cuando los nombres de las veintenas por última vez coincidieron con las estaciones. El presente trabajo revisa sus conceptos y cálculos.Summary: As it is known, several researchers observed that in the sixteenth century, the meanings of the names of the twenty-day cycles of the Mexica calendar do not match the cycle of the seasons. As the vague Mexica year (Xihuitl) of 365 is approximately a quarter of a day shorter than the tropical year (also known as a solar year) of 365.2422 days, the Mexica year (Xihuitl) used to supplant the tropical year at a steady rhythm. Michel Graulich (1976, 1979) assumed that the lack of coincidence between the names of the rituals and of the twenty-day cycles with the seasons of the year was due to the firm nature of the passage of time and by calculating backwards, he concluded that the names of the twenty-day cycles coincided with the seasons was during the period from 680 to 683 A.D. This paper reviews his concepts and calculations.Résumé : De nombreux chercheurs ont observé qu’au XVIe siècle, la signification des noms des vingtaines du calendrier mexica ne coïncidait pas avec le cycle des saisons. L’année vague mexica (xihuitl) de 365 jours comptant un quart de jour de moins que l’année tropique de 365,2422 jours, elle s’est décalée vis-à-vis de cette dernière à un rythme constant. Michel Graulich (1976, 1979) a déduit que l’absence de correspondance entre les noms des rites ou des vingtaines et les saisons était dû à ce déphasage progressif et, en remontant dans le temps, il a calculé que c’est vers 680-683 E.C. que les noms des vingtaines avaient coïncidé pour la dernière fois avec les saisons de l’année. Le présent article révise ses concepts et ses calculs.

Beyond Rhetoric: How Context Influences Education Policy Advocates’ Success
Authors: Winton Sue , Jervis Lauren 
Published: February 2019

This article discusses findings from a study of a 22-year campaign to change special education assessment policy in Ontario by the advocacy organization People for Education (P4E) and explains how dominant discourses enabled the government to leave the issue unresolved. Based on a rhetorical analysis of 58 documents, the article identifies strategies used by P4E to persuade Ontario’s government and citizens to view students’ uneven access to educational assessments as a problem. Further, since this problem differently impacts children by class and geographical location, it perpetuates inequities. Despite using strategies deemed effective in other change efforts, arguments mobilized by P4E have not been persuasive in a neoliberal context that champions responsibilized individualism, meritocracy, human capital development, and reduced funding of public services.

Balancing altruism and self-interest: GP and patient implications
Authors: O’Riordan Chris 
Published: February 2019

Abstract
This paper explores how general practitioners (GPs) address potentially opposing motivations stemming from being altruistic and self-interested, and the implications for patients and GPs. The author finds that GPs address dual goals of patient care and profit generation. This can be challenging, while professional values (altruism) encourage a patient focus, business realities (self-interest) mandate other priorities. Viewing clinicians as altruistic in isolation of business needs is unrealistic, as is the notion that profit is the dominant motivation. A blending of interests occurs, pursuing reasonable self-interest, patients’ best interests are ultimately met. GPs need a profit focus to sustain/improve the practice, benefitting patients through continued availability and capacity for enhancement. Therefore, it is argued that GPs behave in a manner that is ‘part altruistic, part self-interested’ and mutually beneficial. These insights should be considered in designing incentive systems for GPs, raising compelling questions about contemporary understanding of the nature of professionals.

Authors: MAFRA Adriana Luiz Sartoreto , SILVA Adriana da , BENTO Carina Adriele 
Published: February 2019

A Esclerose Lateral Amiotrófica (ELA) é uma doença neurodegenerativa caracterizada pela depleção progressiva dos neurônios motores superiores e inferiores. Nestes anos, modificações profundas no atendimento e tratamento para o doente de ELA ocorreram, além do reconhecimento que a mesma não afeta somente a pessoa com a doença, mas causa um profundo impacto na famí­lia e, especialmente, naquela pessoa mais próima do paciente que, frequentemente torna-se o seu cuidador. O objetivo do presente estudo foi definir o que é ELA traçando um breve relato epidemiológico da doença no mundo e no Brasil, descrevendo seu quadro clínico e etiológico, assim como seu diagnóstico e tratamento, buscando avaliar a qualidade de vida do doente e identificar os cuidados que devem ser realizados com o doente pelos profissionais da saúde. Para o alcance do objetivo geral e os especí­ficos, optamos pelo método da revisão de literatura. O levantamento bibliográfico foi realizado pela Internet, no banco de dados Lilacs (Literatura Latino-Americana em Ciências de Saúde) e na base de dados BDENF (Base de Dados Bibliográficos Especializada na área de Enfermagem do Brasil), consideradas as principais da área da saúde brasileira. Determinar quais são os fatores que causam impacto na vida dos indiví­duos com ELA pode auxiliar na tomada de decisões e na elaboração de planejamentos e de intervenções, tratamento e servios. Intervenções especificamente desenhadas para aumentar a efetividade da relação entre pacientes e cuidadores podem melhorar o bem-estar psicológico de ambas as partes.
