Authors: Quang Le Nhat , Tram Le Thi Bich , Thuy Nguyen Huyen Minh , Toan Pham Duong , Vinh Dang Quang , Huyen Nguyen Thi Thuong 
Published: December 2018

Background: Results from the latest meta-analysis, in fresh cycles, showed that the application of time-lapse monitoring (TLM) together with an embryo-evaluating algorithm was associated with a significantly higher rate of ongoing pregnancy and a lower rate of early pregnancy loss. The aim of this study was to compare the clinical outcomes of frozen embryos classified according to morphokinetic versus morphologic criteria.
Methods: This was a retrospective cohort study, conducted at IVFAS, An Sinh Hospital, Vietnam, from July 2014 to July 2017. Patients undergoing in vitro fertilization (IVF) treatment with antagonist protocol and having freeze-only on day 5 were included. Exclusion criteria were patients (i) treated with in-vitro maturation, (ii) having obstructive azoospermia, or (iii) having uterine abnormalities. Embryos were cultured up to day 5 in TLM system (Primo Vision, Vitrolife, Sweden) or in benchtop (G185, K System, Denmark). The quality of frozen embryos was evaluated based on morphokinetic or morphologic criteria. In the subsequent cycle, endometrial preparation was done by using exogenous estradiol and progesterone. Embryos were thawed and up to 2 embryos were transferred to the uterus. The primary outcome was ongoing pregnancy. The rate of post-thaw survival, post-thawed good/moderate embryo, clinical pregnancy, implantation, miscarriage and ectopic pregnancy were used as secondary endpoints.
Results: A total of 276 patients were recruited, with 138 patients in the morphokinetic group and 138 patients in the morphologic group. Baseline characteristics were comparable between the two groups. There was no significant difference in ongoing pregnancy rate in morphokinetic versus morphologic group (57.2% vs. 60.1%, p=0.71). All secondary outcomes were comparable between the two groups.
Conclusion: In frozen day-5 embryo transfer, the clinical outcomes were similar when embryos were classified according to morphokinetic versus morphologic criteria for freezing. Using morphokinetic criteria to select embryos for freezing did not improve the ongoing pregnancy rate, as compared to morphologic criteria.
Energy expenditure, recovery oxygen consumption, and substrate oxidation during and after body weight resistance exercise with slow movement compared to treadmill walking
Authors: Nakagata T , Yamada Y , Naito H 
Published: December 2018

The benefit of body weight resistance exercise with slow movement (BWRE-slow) for muscle function is well-documented, but not for energy metabolism. We aimed to examine physiological responses [e.g., energy expenditure (EE), respiratory exchange ratio (RER), and blood lactate (La)] during and after BWRE-slow compared to EE-matched treadmill walking (TW). Eight healthy young men (23.4 ± 1.8 years old, 171.2 ± 6.2 cm, 63.0 ± 4.8 kg) performed squat, push-up, lunge, heel-raise, hip-lift, and crunch exercises with BWRE-slow modality. Both the concentric and eccentric phases were set to 3 s. A total of three sets (10 repetitions) with 30 s rest between sets were performed for each exercise (26.5 min). On another day, subjects walked on a treadmill for 26.5 min during which EE during exercise was matched to that of BWRE-slow with the researcher controlling the treadmill speed manually. The time course changes of EE and RER were measured. The EE during exercise for BWRE-slow (92.6 ± 16.0 kcal for 26.5 min) was not significantly different from the EE during exercise for TW (95.5 ± 14.1 kcal, p = 0.36). BWRE-slow elicited greater recovery EE (40.55 ± 3.88 kcal for 30 min) than TW (37.61 ± 3.19 kcal, p = 0.029). RER was significantly higher in BWRE-slow during and 0–5 min after exercise, but became significantly lower during 25–30 min after exercise, suggesting greater lipid oxidation was induced about 30 min after exercise in BWRE-slow compared to TW. We also indicated that BWRE-slow has 3.1 metabolic equivalents in average, which is categorized as moderate-intensity physical activity.
A generalisation to cohesive cracks evolution under effects of non-uniform stress field
Authors: Pham Tuan-Hiep , Laverne Jérôme , Marigo Jean-Jacques 
Published: December 2018

The aim of the present work is to study the stabilizing effect of the non-uniformity of the stress field on the cohesive cracks evolution in two-dimensional elastic structures. The crack evolution is governed by Dugdale's or Barenblatt's cohesive force models. We distinguish two stages in the crack evolution: the first one where all the crack is submitted to cohesive forces, followed by a second one where a non cohesive part appears. Assuming that the material characteristic length dc associated with the cohesive model is small by comparison to the dimension L of the body, we develop a two-scale approach, and using the complex analysis method, we obtain the entire crack evolution with the loading in a closed form for the Dugdale's case and in semi-analytical form for the Barenblatt's case. In particular, we show that the propagation is stable during the first stage, but becomes unstable with a brutal jump of the crack length as soon as the non cohesive crack part appears. We discuss also the influence of all the parameters of the problem, in particular the non-uniform stress and cohesive model formulations, and study the sensitivity to imperfections.

Our aim was to evaluate the anti-tumor necrosis factor
(TNF) response to treatment, which has been in place in the treatment of Rheumatoid Arthritis(RA) andAnkylosing Spondylitis(AS) patients in recent years and has achieved successful results. In this regard,
the follow-up of the disease
is more predictable after the initiation of anti-TNF
therapy; it is aimed to interpret the parameters
used in follow-up more correctly.This
cross-sectional, retrospective study was performed in auniversity hospital between 2010-2016. Files of 24 patients
with AS and 53 patients with RAwere
retrospectively screened. Their clinical situations and laboratory levels were compared before and after the biological
agent treatment. Treatment response with RA was evaluated by Disease Activity Score-28 (DAS28) scale
and AS patients’ treatment response was evaluated
by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scale..A
total of 77 patients were included in the study. Of the participants, 53 were diagnosed as RA and 24 were diagnosed as AS. After
our
study
we
have
determined
statistically reasonable decrease in C-Reactive
protein
(CRP),
white
blood
cell
(wbc),
Platelete, erythrocyte sedimentation rate (ESR) levels but an increase in blood urea nitrogene
(BUN), haemoglobine (Hb), Albumin levels.
The mean baseline
score of BASDAI assessed
before the treatment
in 24 patients with AS was 6.08 and after the treatment
was 3.42; DAS-28 assessed before the treatment
was 5,77 and after the treatment was 3,58 and these
differences was statistically significant.

Patients
treated with biological agents showed a significant improvement in clinical
assessment evaluated by BASDAI in patients with AS and DAS28 in patients with RA.
Significant decrease in CRP, ESH, wbc levels, improvement in chronic disease anemia, increase in albumin level as a negative acute
phase reactant and decrease in thrombocyte
levels were determined because of acute phase
response and regression of inflammation.

ICT-mediated education in youth and adult literacy programmes in the Dominican Republic: an approach to the state of the art
Authors: Sena Rivas Wiselis Rosanna , Herrero Gutiérrez Francisco Javier , Casillas Martín Sonia 
Published: December 2018

ABSTRACT:This research focuses on the relation between Education and ICT/Internet in the Dominican Republic. Specifically, we focus on the context of basic literacy education in young people and adults, the overall aim being to learn the extent to which ICT are used in adult education in that country. To this end, we administered a questionnaire to a sample of teachers to learn what digital resources they have access to, how they are used, and a diagnosis of self-perceived digital competences. The main results point to an ever-increasing number of resources for use in the classroom, although there is still room for improvement. Moreover, the implantation of the Internet as a basic tool for strengthening the educational system is progressing but is not yet complete. We conclude that the lack of resources may be partially contributing to this shortfall in immersion in the new technologies, but that it is necessary to continue to implement programs to reinforce the digital competences of teachers, even at a basic level and taking particular account of older teachers. This would certainly improve the teaching-learning process, especially if we consider that the teachers themselves consider ICT as a key factor in the educational process.KEYWORDS: ICT; education; Dominican Republic; youth and adult literacy programmes; basic digital resources. RESUMO: Esta pesquisa enfoca a relação entre Educação e TIC/Internet na República Dominicana. Especificamente, nos concentramos no contexto da educação básica em alfabetização em jovens e adultos, com o objetivo geral de compreender até que ponto as TIC são usadas na educação de adultos nesse país. Para isso, aplicamos um questionário a uma amostra de professores para saber a que recursos digitais eles têm acesso, como são usados e o diagnóstico de competências digitais percebidas por eles mesmos. Os principais resultados apontam para um número cada vez maior de recursos para uso em sala de aula, embora ainda haja espaço para melhorias. Além disso, a implantação da Internet como ferramenta básica para o fortalecimento do sistema educacional está progredindo, mas ainda não está completa. Concluímos que a falta de recursos pode estar contribuindo parcialmente para essa deficiência na imersão nas novas tecnologias, mas que é necessário continuar a implementar programas para reforçar as competências digitais dos professores, mesmo em um nível básico e tendo particularmente em conta os professores mais velhos. Isso certamente melhoraria o processo de ensino-aprendizagem, especialmente se considerarmos que os próprios professores consideram as TIC como um fator-chave no processo educacional.PALAVRAS-CHAVE: TIC; educação; República Dominicana; programas de alfabetização de jovens e adultos; recursos digitais básicos.

A predictive factor for axillary lymph node metastasis in invasive ductal breast cancer: the value of tumor and breast volume ratio
Authors: Kubat Mehmet , Dinç Soykan 
Published: December 2018

Background: The objective of this study was to witness the effect of tumor volume/breast volume ratio on the presence of axillary lymph node metastasis and to examine the strategy in surgical treatment approach for patients.Methods: This study was carried out prospectively by examining the patients undergoing modified radical mastectomy surgery due to breast cancer (n=99). Breast volumes were measured through liquid overflow method in graduated bowl tumor volume was measured according to ellipsoid volume formula with diameters determined by pathological specimen, ultrasonography or MRI.Results: Axillary lymph node metastasis (ALNM) was positive in 64.6% of them (n=64). Average breast volume was found to be 693.89cm³ in the measurement of mastectomy materials. Average tumor volume was found to be 9.58cm³. In line with these results, average tumor volume/breast volume (vTm/vMm) ratio was: 0.0176. Author found axillary lymph node metastasis possibility significantly higher in patients with vTm/vMm ratio>0.016 (Odds ratio 9.437, p-value 0.007).Conclusions: The presence of ALNM is the most important factor in indicating the prognosis of patients with invasive breast cancer and planning the treatment. Thus, knowing whether there exists an ALNM or not during preoperative period draws the attention of both the doctors performing treatment and patients. In this study efficiencies of largest tumor diameter, tumor volume and tumor volume (vTm)/Breast volume (vMm) ratio in indicating ALNM presence in cases with T2 invasive ductal breast cancer were evaluated. It was found that vTm/vMm ratio was a recent and effective prognostic criterion in determining ALNM.

Published: December 2018

Background: Wound closure techniques have evolved from suture material to advanced techniques that include skin staplers, skin glue and adhesive tapes. Based on efficacy of advanced suturing techniques patient may be benefited with better cosmesis, lesser postoperative pain, less wound infection and lesser hospital stay. The aim of the study was to compare the results of adhesive glue with suture material in skin closure in hernia surgeries.Methods: This study involves 100 patients undergoing open inguinal hernia surgery. In 50 of the patient’s skin closure was done with conventional suturing (3-0 ETHILON) and other 50 patients with tissue glue (2-octyl cyanoacrylate). Observation regarding postoperative pain, skin closure time and scar assessment were made, and their results were compared.Results: The mean time taken for skin closure in adhesive group was 2.72±1.32minutes and that of suture group was 4.88±1.533minutes. This difference was of great significance with p value of <0.001. The visual analogue scale shows mean value of 5.3±0.68 for suture group and for skin group it was 3.68±0.62. This value was of great significance with p value <0.001. Postoperative pain was comparatively less in tissue glue group. Postoperative scar was analysed with Vancouver scar scale at regular intervals. The mean score for suture group was 8.3±0.8 and for skin glue group it was 2.8±0.75. These differences of score was of great significance with p value <0.001.Conclusions: Adhesive glue is superior to conventional suturing in clean elective surgeries. It is a safe and an effective method of skin closure with less postoperative pain and better cosmesis of the scar.
