OBJETIVO: Investigar os riscos ergonômicos e biomecânicos ocupacionais em profissionais da enfermagem no transporte de pacientes, no centro cirúrgico de um hospital público. METODOLOGIA: Estudo de caráter exploratório, observacional e descritivo. Para tanto, utilizou-se o Questionário Internacional da Atividade Física (IPAQ), que analisa diferentes contextos do cotidiano para estimar o tempo semanal gasto em caminhadas, atividades físicas de intensidade moderada, vigorosa e atividades passivas (tempo sentado). O Questionário Nórdico, possibilita a identificação de distúrbios osteomusculares nos 12 meses e 7 dias anteriores à entrevista. Permite também um diagnóstico do posto de trabalho pela sua relação com a prevalência do local e tempo do surgimento dos sintomas dolorosos. Além disso, aplicou-se a metodologia da Análise Ergonômica do Trabalho (AET). RESULTADOS: De acordo com a análise dos dados coletados participaram deste estudo 44 profissionais da enfermagem, 32 (72,7%) eram do gênero feminino e 13 (29,54%) do gênero masculino. Quando analisado a especialidade: 24 (54,5 %) eram auxiliares de enfermagem, técnicos de enfermagem correspondem à 14 (31,8 %) e Enfermeiros 6 (13,6 %). O questionário IPAQ demonstrou que 16 (35%), destes profissionais mantém-se ativos. Por meio da análise ergonômica do trabalho, as variáveis como, tipo de maca, condições de manutenção, tipo de anestesia, idade do paciente, entre outros, interferem em maiores ou menores esforços no transporte de pacientes. CONCLUSÃO: Desse modo, tornam-se necessárias a adoção de medidas preventivas que visem a melhoria do estado de saúde prevenindo complicações musculoesqueléticas no desempenho das atividades. Além de promover boas condições de trabalho aos profissionais no seu ambiente profissional, bem como trazer benefícios ao hospital.
THE ROLE OF SELF-DISCREPANCY IN GENERATING FUTURE ANXIETY AMONG UNIVERSITY STUDENTS
Authors: Mohammed Al-Ferhat Basem , Saleh Jarwan Ali , J. Zuraikat Malek 
Published: December 2019

Purpose of the study: The current study examines the level of self-perception (realism, idealism, and duty) among Yarmouk University students. It also identifies the level of their self-discrepancy and its relation to future anxiety and explores the differences regarding the level of these self-discrepancies and the future anxiety according to the variables of specialization, the level of the study, and GPA. The study argues that while there is a significant statistical negative relationship between the level of future anxiety and the actual self among university students there is no significant statistical correlation between the level of future anxiety and the ideal self and the ought self.
Methodology: The study was conducted on a sample of (200) university students of the Faculty of Education at Yarmouk University. Higgins’ (1987) scale which consists of (30) paragraphs and the scale of future anxiety which consists of (27) paragraphs were applied to the study sample using the descriptive correlational approach.
Main Findings: There were no significant statistical differences regarding the level of self-discrepancy (real/ideal) and (real/due) due to the variables of specialization, the level of study, and the GPA. Also, there were no significant differences regarding the level of future anxiety among Yarmouk University students according to the variables of specialization, the level of study, and the GPA. Yet, there was a statistically significant negative relationship between the level of future anxiety and the actual self.
Applications of this study: Universities across the globe, such as Yarmouk University and the University of Jordan, may find it significant to know that university students have a moderate level of self-perception and do not have a correspondence between the characteristics of the self in its three dimensions. Thus, such universities may need to think of establishing certain training and counseling programs that aim at developing the students' perception of themselves and their understanding of the self.
Novelty/Originality of this study: Considering that a few Arabic studies address future anxiety among university students who will graduate and impact their local communities, the paper points at the need for establishing certain counseling courses that help university students better understand themselves and decide their needs accordingly.
A STUDY OF EFFECT OF DEMOGRAPHIC FACTORS ON E-GOVERNMENT DIVIDE IN THE REPUBLIC OF MAURITIUS
Authors: Sanmukhiya Chintamanee 
Published: December 2019

Republic of Mauritius. Findings would encourage wider e-participation and e-inclusion into policy-making from all segments of the population.
Methodology: A stratified random sample of 310 users and non-users of e-government was used. Logistic regression was estimated. The non-significant Hosmer-Lemeshow test and the Nagelkerke R2 of 0.538 imply that the logit model is useful in predicting the e-government divide.
Main Findings: The classification table shows 81% correct classification. All Wald Chi-Square statistics are reported. This research reveals that marital status and gender do not predict the e-government divide. Age (p<0.01), education (p<0.001), middle income range (p<0.05), dwellership (p<0.01) and public sector employment (p<0.05) affect a citizen’s decision to adopt e-government. The massive investments in e-government initiatives cannot be justified as these have not catered for universal coverage. Young citizens are 20 times more likely than old citizens to adopt e-government.
Implications/Applications: The tendency to use e-government increases as more education is acquired. Rural dwellership almost triples the odds of e-government adoption although these citizens are less educated than their urban counterparts. Public sector employees are 3.6 times more likely to use government websites than the self-employed. Monthly income earners of Rs 20001 to Rs 35000 are 3.3 times more likely to use e-government services than those earning up to Rs 10000. This study is ground-breaking and challenges the belief that rural dwellers are marginalized and reinforces the importance of education within the theoretical framework of the e-government divide.

Published: December 2019

Purpose: The purpose of this study is to investigate the prevalence of posttraumatic distress disorder (PTSD) and depression among children in Gaza, Palestine.
Methodology: This study assessed the psychological effects of the Israeli-Palestinian conflict on children in the Gaza Strip. 286 children aged 9-14 years old, who were exposed to a wide range of war events, were selected from the Gaza Strip to participate in this study. All participants conducted the following scales: the child PTSD Reaction Index(CPTSD-RI), Beck Depression Inventory (BDI), and the Arabic version for PTSD and depression assessment.
Finding: The results show that the mean number of participants witnessing home destroyed and people killed was (88%) and home invasion (76%). Approximately 70% of the participants reported that they witnessed war violence against at least one of their family members. Further, 44 % of the children have a least one death in their family due to the Israeli invasion. Using t-tests, we found that significantly more females have both PTSD and depression than males. Approximately 32.8% of the participants met the criteria for severe depression, and 42.6 % met the criteria for PTSD.
Implications: Our results suggest that it is imperative to provide intervention programs to treat PTSD and depression symptoms among children in Gaza. These programs should take into account the cultural and religious background of the participants.
Originality: This investigation of the Israeli-Palestinian conflict has led to an increase in PTSD and depression symptoms among children in the Gaza Strip.

Aim: The aim of this study was to detect preoperative and intraoperative dental malpractice in the field of implant dentistry in the Kingdom of Saudi Arabia.
Materials and Methods: 115 patients aged ≥ 18 years with at least one professional malpractice in implant dentistry done in dental health premises in Saudi Arabia were included in the study. Clinical and Radiographic examinations were used to detect preoperative complications (poor patient selection, diagnosis, inappropriate treatment planning) and intraoperative complications (damage to adjacent tooth, inferior alveolar nerve damage, sinus penetration, and implant positional failure due to poor surgical execution).The data obtained including age and gender were documented in a patient examination form then statistically analyzed using Chi-Square Test and Spearman’s Correlation Coefficient.
Results: More than half of the patients were females (62.6%). The majority of the patients were in the age group 50-60 years (31.3%). Also, the majority of the patients had implants with malpractice placed in the posterior region. Exactly half of the patients had implants with malpractice placed in the maxilla. In addition, exactly half of the patients had technical errors violating the surrounding structures; (39.1%) of the patients had damage to adjacent tooth, (11.3%) had inferior alveolar nerve damage, and (4.3%) had sinus penetration.
Conclusion: Patients were equally divided between implant positional failure due to preoperative inappropriate treatment planning and that due to intraoperative poor surgical execution. Solid theoretical knowledge and polished surgical skills are key success factors for accurate implant placement.

Published: December 2019

Grass can be said to be one of the most successful land plants and is found in all types of growing sites and a variety of circumstances. The Poaceae family is the fourth largest family of flowering plants in the world and there are around 11,000 species with 800 genera. A large diversity of species characterizes a stable community. The term swamp is generally closely related to the conditions of standing water, tidal overflows, floods, and mud. This study aims to identify and find out the diversity index (H') of the Poaceae family in the swamp area of Sungai Lumbah village, Barito Kuala district. The steps of this research are determining the location of the study, observing and identifying species, counting the number of clumps per species at each sample point, tabulating data to obtain the diversity index (H '), measuring environmental parameters. Based on observations, 14 species of the Poaceae family were found, namely Bambusa sp., Brachiaria mutica, Digitaria longiflora, Eleusine indica, Eragrostis unioloides, Imperata cylindrica, Ischaemum muticum, Oryza sativa, Panicum paludosum, Panicum repens, Paspalum commersonii, Paspalum conjugatum, Phragmites vallatoria, and Saccharum officinarum. The Poaceae family diversity index in the swampy area of Sungai Lumbah village is moderate (H' = 2.49).

Published: December 2019

Background:
We introduce a quantitative measure of epiphyseal cartilage vascularity and examine vessel networks during human skeletal maturation. Understanding early morphological changes in the distal femoral condyle is expected to provide information on the pathogenesis of developmental diseases such as juvenile osteochondritis dissecans.

Methods:
Twenty-two cadaveric knees from donors ranging from 1 month to 10 years of age were included in the study. Images of bone, cartilage, and vascularity were acquired simultaneously with a 3-dimensional gradient-recalled-echo magnetic resonance imaging (MRI) sequence. The secondary ossification center volume and total epiphysis cartilage volume ratio and articular-epiphyseal cartilage complex and epiphyseal cartilage widths were measured. Epiphyseal cartilage vascularity was visualized for 9 data sets with quantitative susceptibility mapping and vessel filtering, resulting in 3-dimensional data to inform vessel network segmentation and to calculate vascular density.

Results:
Three distinct, non-anastomosing vascular networks (2 peripheral and 1 central) supply the distal femoral epiphyseal cartilage. The central network begins regression as early as 3 months and is absent by 4 years. From 1 month to 3 years, the ratio of central to peripheral vascular area density decreased from 1.0 to 0.5, and the ratio of central to peripheral vascular skeletal density decreased from 0.9 to 0.6. A narrow, peripheral vascular rim was present at 8 years but had disappeared by 10 years. The secondary ossification center progressively acquires the shape of the articular-epiphyseal cartilage complex by 8 years of age, and the central areas of the medial and lateral femoral condyles are the last to ossify.

Conclusions:
Using cadaveric pediatric knees, we provide quantitative, 3-dimensional measures of epiphyseal cartilage vascular regression during skeletal development using vessel image features. Central areas with both early vascular regression and delayed ossification correspond to predilection sites of juvenile osteochondritis dissecans in this limited case series. Our findings highlight specific vascular vulnerabilities that may lead to improved understanding of the pathogenesis and better-informed clinical management decisions in developmental skeletal diseases.

Clinical Relevance:
This paradigm shift in understanding of juvenile osteochondritis dissecans etiology and disease progression may critically impact future patient management. Our findings highlight specific vascular vulnerabilities during skeletal maturation in a group of active young patients seen primarily by orthopaedic surgeons and sports medicine professionals.

Published: December 2019

Abstract
Background:Axillary ultrasound (AUS) is one of the important bases for evaluating the axillary status of breast cancer patients. And it would be helpful for the reassessment of axillary lymph node status in these patients after neoadjuvant chemotherapy(NAC) and guide the selection of their axillary surgical options.The purpose of this study was to evaluate the diagnostic performance of ultrasound,and to find out the factors related to the outcome of ultrasound. Methods:In this retrospective analysis, 172 patients (one bilateral breast cancer) with breast cancer and clinical positive axillary nodes, were enrolled. After NAC, all patients received mastectomy and axillary lymph node dissection (ALND). AUS was used before and after NAC to assess the axilla status. Results:Of the 173 axillae, 137 (79.19%) had pathological metastasis after NAC. The accuracy, sensitivity, specificity, positive predictive value and negative predictive value of axillary ultrasound in this cohort were 68.21%, 69.34%, 63.89%, 87.96% and 35.38% respectively. Univariate analysis showed that primary axillary lymph node(ALN) short axis, progesterone receptors, hormone receptors, the tumor status after NAC, tumor reduction rate, ALN short axis after NAC, physical examination of axilla after NAC and pN impacted the results of AUS(P = 0.000 ~ 0.040). Multivariate analysis of the above indicators showed that ALN short axis after NAC and pN associated with AUS results independently. Conclusion:AUS can accurately assess axilla status after NAC in most breast cancer patients. If the short axis of ALN≥10mm and AUS negative, SLNB could be chosen. However, AUS cannot detect residual lymph node disease after NAC in a short axis of the ALN <10mm.

Abstract
Background The perinatal mortality rates are five times higher in twin pregnancies than singleton pregnancies, therefore antenatal management and safe delivery of twin pregnancies are important issues in obstetrics. This study aimed at providing data on the proportion of twin deliveries in four public hospitals in Dar es Salaam and an insight on the fetal outcomes in relation to their modes of delivery.Methods This was a cross sectional study in which all women who delivered twin babies were interviewed and medical records on their delivery summary were obtained in the labour and post-natal wards in four public hospitals in Dar es Salaam between July and December 2011. Post-natal follow up was done on seventh day by contacting women by telephone to establish the neonatal status.Results There were 33,638 total deliveries of which 672 were twin deliveries making the prevalence of 2.0% (20 per 1,000 births). Of all twin deliveries analyzed (666 pairs), 373(56.0%) had the diagnosis of twin pregnancy made antenatally. Vaginal delivery was the major mode of delivery (77.3%). whereas combined delivery in which the first twin was delivered vaginally and the second twin by caesarian section accounted for only 2.6%. At birth 1252(94%) of twins were alive, 60(4.5%), were fresh stillbirths and 20(1.5%) were macerated stillbirths. Low Apgar score was more to first twins delivered vaginally compared to first twins (p-value=0.003). Low Apgar score (AS <7) was more amongst second twins delivered vaginally at 30 minutes or longer 27(48.2%) compared to twins delivered in less than 30 minutes 72(15.4%), (p-value=0.001).Conclusion There was a significant association between vaginal delivery and low Apgar score at one minute. Long duration of twin to twin delivery interval was associated with low Apgar score of the second twins delivered vaginally. Perinatal mortality rate was also higher in the second twins compared to the first twins. The time delivery interval of the second twin should be made as short as possible by active management of all second twins. Neonatal facilities are required in all hospitals conducting twin deliveries to care for premature babies.

Abstract
Background: Monocytes play a crucial role in Alzheimer's disease (AD), and docosahexaenoic acid (DHA) treatment has a neuroprotective effect for many neurodegenerative diseases. However, mechanisms that regulate monocyte and Aβ protein interaction in AD and the effects of DHA on monocytes in the context of AD are not fully understood. Methods: The experiments were designed to further explore possible mechanisms of interaction between monocytes and Aβ plaques. Another objective of this study was to investigate a potential mechanism for Aβ-mediated regulation of necroptosis and the MAPK and NF-kB signaling pathways, as well as how these pathways might be modulated by DHA in human THP-1 monocytes. We also investigated whether DHA indirectly suppressed THP-1 cell-mediated neuronal activation. We used cell viability and cytotoxicity assays, flow cytometry, transwell migration assays, and Western blotting to perform our study. Results: Our findings indicate that Aβ25-35 regulates two aspects of THP-1 cells necroptosis. We also observed that increased resistance to apoptosis in THP-1 cells that is correlated with THP-1 monocyte differentiation. Our results also indicated that DHA treatment restored migration of THP-1 monocytes that had been treated with Aβ25–35. Pre-treatment of THP-1 monocytes with DHA effectively inhibited Aβ-induced activation and markedly suppressed protein expression of TNF-α，IL-1β and IL-6. We also found that THP-1 cell necroptosis was induced by Aβ25–35 through modulation of RIPK1/RIPK3 and phosphorylation status of ERK1/2 and could be attenuated by DHA treatment. Conclusion: Aβ25–35-mediated induction of necroptosis through activation of the RIPK1/RIPK3 and RIPK1/ ERK1/2 signaling pathways in THP-1 monocytes can be attenuated by DHA treatment, indicating that DHA treatment could be a promising new therapy for AD management.
