Authors: Kiran Sneh , Sinha Abha Rani
Published: March 2018

Background: Present study was undertaken to evaluate the effectiveness and safety of intrapartum modified biophysical profile along with vibroacoustic stimulation test in the assessment of fetal well-being compared with modified biophysical profile for women with a singleton pregnancy.Methods: This prospective study was carried out on a group of pregnant women of gestational age more than 35 weeks attending the labour room of obstetrics and gynecological department of Patna medical college and hospital, from October 2013 to October 2015. A total 220 pregnant women were selected and randomly divided into two groups, 110 women were given modified biophysical profile and 110 were underwent modified biophysical profile with VAST.Results: Among 110 women, who underwent modified biophysical profile, 80(72.7%) showed reactive response and 30(27.3%) showed non-reactive response. A total 110 women, in whom modified biophysical profile was combined with VAST, 100(91%) showed reactive response and 10 (9%) showed non-reactive response. Statistical comparison for predicting perinatal mortality was done. Modified biophysical profile with VAST had a high sensitivity (100% vs. 80%), specificity (92.5% vs. 75.2%), negative predictive value (100% vs. 98.7%) and positive predictive value (20% vs. 13.3%) as compared to modified biophysical profile. Test accuracy for predicting perinatal mortality was more than mBPP (92.7% vs.75.4%).Conclusions: Addition of VAST in place of NST in modified biophysical profile has high specificity & positive predictive value, shortens the testing time.

Authors: Abbas Ahmed M. , Ali Shymaa S. , Nagy Mohammed , Nasif Fady
Published: March 2018

Cases of Caesarean Scar Ectopic Pregnancy (CSEP) are becoming increasingly common at tertiary care hospitals because of increase in rate of CS. It may lead to horrible consequences, such as uncontrolled bleeding and uterine rupture (UR), which might require hysterectomy and result in subsequent loss of fertility. This report covers a case of a CSEP discovered early at 9 weeks of gestation in a 25-year-old woman coming for antenatal care. Conservative management of the uterus was performed with removal of the sac and repair of the uterine scar. The patient’s postoperative period was uneventful, and she was discharged 3 days after surgery. CSEP should be detected early to prevent its catastrophic sequences. Although it is a rare complication of cesarean section, CSEP must be kept in the minds of obstetricians facing emergency cases.

La neumatosis gástrica es la presencia de aire en la pared del estómago. Es un signo radiológico extremadamente raro en pediatría causado por lesiones microscópicas de la mucosa gástrica. Se presentan cuatro casos de pacientes pediátricos con diagnóstico de neumatosis gástrica atendidos entre el 1 de enero de 2010 y el 31 de diciembre de 2015. Los pacientes presentaron similitudes en sus síntomas como vómito, fiebre y dolor abdominal. El caso dos tuvo antecedente personal patológico de síndrome de Down y el caso cuatro antecedente de laparotomía exploradora por torsión axial del estómago. Se sometieron a cirugía todos los casos con diagnóstico preoperatorio de neumatosis gástrica. Los casos 1 y 4 fueron objeto de segunda intervención quirúrgica por obstrucción intestinal. Se analizan 4 de 5 diagnósticos debido a que un caso clínico no contó con diagnóstico operatorio pues el paciente causó alta voluntaria. La neumatosis gástrica es un signo radiológico que, de acuerdo con sus características, orienta a sospechar una obstrucción gastroduodenal.

CAUSAL FACTORS OF DISHARMONY ISSUES ON LICENSING COASTAL RECLAMATION IN SAMPANG AND BANGKALAN REGENCIES
Authors: Yulianti Rina , Ikhwan Mufarrijul
Published: March 2018

This research is to investigate the contributing factors on the disharmony of licensing coastal reclamation in Sampang and Bangkalan Regencies. Socio legal research approach was used through indepth interviews and observations. The study was conducted in areas with reclamation activities and subsequently considering the relevant documents to analyze as the secondary data. The findings of this research demonstrate factors leading to disharmony of licensing coastal reclamation: the regional government of Sampang and Bangkalan regencies has not synchronized the reclamation policies with the presidential regulation. Reclamation in Sampang and Bangkalan are not based on the Presidential Regulations Number 122 Year 2012 on the Licensing Coastal Reclamation. The license of reclamation in Sampang should have been issued by district or provincial government instead of by the head of village. Reclamation license in Bangkalan should have been issued by the Ministry of Maritime Affairs and Fisheries because it is located in the National Strategic Areas. The fact, it was granted by the local government. Harmonization consequently becomes an important part to construct an integrative law for realizing central and local authority’s conformity in introducing the policy to control of coastal spatial utilization. Keywords: coastal, disharmony, licensing, reclamation.
SUSTAINED CHARACTER BUILDING THROUGH LITERATURE FOR COLLEGE STUDENTS IN INDONESIA
Authors: Hariyanti Tatit , Sudjito Sudjito
Published: March 2018

This article aims at promoting sustained character building through literature especially for college students in Indonesia. Till present, the character building has been restricted to the embedment of good virtues to children and adolescents. The majority of existing studies and researches, therefore, tend to focus their attention on such limited area. Character building ought to be a sustainable effort halted not when one finishes his/her study at elementary or intermediate  grades. It should be maintained all life long. There are two highlighted problems which are going to explore in this paper: first, why literature is still considered to be one of the effective media to establish sustained character building for college students and second, what appropriate Instructional Strategies to con-duct such effort are. The result shows that literature is still effective due to its natural characteristics, its wide spectrum, and its dynamically broadened functions. Under the conviction that the students have already been undergoing  the process of embedment of some core values before, the given literary works containing, elaborating and questioning or challenging the given embedded values are taken to be the source of discussion. The instructional strategies cover discussion, debate, seminar, film appreciation, and creative writing. Keywords: character building, instructional strategies, literature, sustained
The Effect of Vibration Therapy on Reduction of Matrix Metalloproteinase-9 in Diabetic Ulcer
Authors: Sari Yunita , Sutrisna Eman , Hartono Hartono , Paes Camila Quinetti
Published: March 2018

One important reason why diabetic ulcer fails to heal is an increase of collagen degradation by matrix metalloproteinase-9 (MMP-9). Vibration therapy is one of complementary therapies which can reduce inflammation and improve reepithelialization. However, up to present, there is no study that investigate the effect of vibration on reduction of MMP-9 in diabetic ulcer. Therefore, the effect of vibration on reduction of collagen degradation in diabetic ulcer is still unknown. If vibration can reduce collagen degradation in diabetic ulcer, nurse can recommend patients to apply vibration not only during inflammation and proliferation phase, but also during maturation phase since MMP-9 also contributes to collagen degradation during maturation phase.The purpose of this study was to investigate the effect of vibration on reduction of MMP-9 in diabetic ulcer. Diabetic rats were divided into two groups, vibration and control groups. The intensity of polymorphonuclears cells (PMNs) and fibroblast, collagen appearance, and the presence of positive cells for MMP-9 were compared. Fibroblast, PMNs and collagen appearance were stained with H and E staining, and MMP-9 was stained by immunohistochemistry method. The difference in the intensity of fibroblast and PMNs was analyzed by Mann-Whitney U test. The result showed that the intensity of PMNs was significantly lower, and the intensity of fibroblast was higher in vibration group than in control. Collagen alignment in the vibration group was more organized in a more regular fashion than in control group. The intensity of positive cells for MMP-9 was lower in the vibration group than in control group. This study showed that vibration could reduce MMP-9, therefore it could be concluded that vibration could reduce collagen degradation of diabetic ulcer. This study bring implication in the clinical setting that vibration therapy should also be applied during maturation phase since MMP-9 is also released in the maturation phase.
“Jelly VAC” for Negative-Pressure Therapy for Complex Wound Closure
Authors: Bergin Patrick F. , Wild Jason R. , Weber Timothy G.
Published: March 2018

Case:

A 35-year-old man sustained an open calcaneal fracture with bone loss, and a 57-year-old woman sustained an avulsion of the entirety of the plantar skin. Both patients were treated with multiple debridements and soft-tissue coverage. “Jelly-VAC” (vacuum-assisted closure) therapy was used after each debridement and during the soft-tissue coverage.

Conclusion:

Jelly-VAC therapy is a promising alternative that allows negative-pressure therapy with the use of ultrasound jelly to prevent air leakage into the wound. We propose using this technique in areas where obtaining a seal is difficult, where VAC therapy is contraindicated because of adhesive dressings (i.e., with damaged or poor-quality skin), or when long-term VAC therapy is needed to prevent wound maceration or there is a need for “VAC holidays.”
Needs analyses for task-based curriculum design: How useful can it be for general purpose L2 courses?
Authors: Liakina Natallia , Michaud Gabriel
Published: March 2018

When designing a task-based language curriculum, it is essential to conduct a needs analysis (NA) to gain insight into the needs and goals of the student population (Long SLA and TBLT 6). This article illustrates the steps of the process by which an NA was designed and implemented in two university-level B2 level oral communication French as a Second Language courses to investigate students’ perceptions of the TBLT approach, students’ motivations, needs and desired outcomes in order to develop task-based syllabi. This article also addresses the challenges of responding to the needs of a diverse student population in order to determine thematic content and to design the authentic real-life tasks that would appeal to different individual students while taking into account the sociolinguistic and cultural context of the Francophone province of Quebec.The NA consisted of an analysis of the Common European Framework of Reference for Languages (CEFR), an online questionnaire given to both students (n = 48) and teachers (n = 8), and semi-structured interviews with students (n = 8). Despite the apparent heterogeneity of the participants in the two general purpose oral communication language classes, results suggest common, domain-independent goals and themes that would sufficiently cater to the needs and objectives of each individual in the group while also meeting the academic requirements of a university-level course.

Background:

Fatty acids are common dietary nutrients particularly in economically developed countries.
Research has revealed that omega-3fatty acids exert beneficial effects in the progression of atherosclerosis
and cardiovascular disease. Moreover, eicosapentaenoic acid and docosahexaenoic acid possess a number of
biological actions which improve cardio-metabolic health. Omega-3 fatty acids display remarkable anti-oxidant,
anti-inflammatory, anti-thrombotic and anti-arrhythmogenic actions. Furthermore, they improve the levels of
triglycerides, glucose metabolism and endothelial function.

Methods:

The aim of this review article is to present physical, biochemical and biological properties of omega-3
fatty acids and summarize the most important mechanisms of action on arterial wall properties and arterial stiffness
in atherosclerosis.

Results:

Omega-3 fatty acids may prevent the progression of atherosclerosis. Endothelial dysfunction and arterial
stiffness can be regulated by the supplementation of omega-3 fatty acids.

Conclusion:

The mechanisms of action of omega-3 fatty acids on cardiovascular health and arterial stiffening
have been established. However, further research is needed in order to translate the conflicting results among the
studies and improve the therapeutic options of cardiovascular disease.
