FEMALE SAUDI DEPENDENT STUDENTS AND LANGUAGE LEARNING INVESTMENT AND RESISTANCE: A CASE STUDY OF FOUR FEMALE MUSLIM SAUDI STUDENTS IN THE US
Driven by Nortons (2012) concept of investment and the role of agency and identity in second language acquisition, this study investigated the relationship between religion, cultural identity, and language learning investment among four female Saudi dependent students in an intensive English institute (IEI) in the US. The study examined how students invested their agency as mothers and wives to learn English and how such factors as their Islamic garb, co-educational classes, family, friends, teachers, and class activities increased or decreased their learning opportunities.Data were collected through semi-structured interviews with each participant. Two had dropped out of the IEI, and two were still enrolled at the time of data collection. Data were also collected by observing the enrolled participants once a week in a language class for two months. Short follow-up interviews were conducted after each observation to learn more about their weekly performance and any challenges they encountered. The findings revealed that aspects of participants religious and cultural identity influenced their investment in learning English. Experiencing a co-educational class for the first time increased the feeling of anxiety toward participating in class for some students, and negative attitudes toward their Islamic garb could also influence their language learning investment in class. As a result, they showed two types of resistance: 1) disengagement from classroom activities as indicated by not attending class, not engaging in activities, skipping exams, and failing courses and 2) resistance against Islamophobia and discrimination, which worked as a facilitator for one student to learn English. Furthermore, these dependent students were expected to meet responsibilities at home, which could constrain their language learning investment. Some resisted their positioning as students and failed to learn English in class because they could not compromise between their roles as wives/mothers and students. In contrast, participants who negotiated their cultural identity found ways to invest in learning English that did not contradict their values, such as practicing with Americans outside class, not sitting next to male classmates, using websites to practice rather than attending social events, reading books, and watching television and movies in English
Effect of Organic Soil Acidity on the Properties of Iraqi Soil
There are many problems with the constructing over organic soils as the existence of these types of soils always produces geotechnical and engineering problems for regional development. The geotechnical properties of inorganic soil greatly differ from organic soils, which is known for its high water content, low shear strength, high compressibility, acidity and long-term settlement. In this paper, two soils are chosen according to its organic content and acidity content then physical and chemical properties is done to know them characteristics and leaching process is performed to reduce its acidity that affect the properties of it and study the change of leaching on these properties. Dry hydrated lime is added to the natural and leached soils depending on the optimum lime content to improve their performance. From the physical tests, shear strength tests and consolidation test it can be noticed that the soils are behave better after leaching as it reduced in plasticity index, compressibility, and swelling and increase in shear strength. Furthermore, the leached soils are needed less percentage of lime content to produce a pH of 12.4 and the stabilized leached organic soils are behave better than the stabilized natural soils.

172650.pdf (publisher's version ) (Open Access)BACKGROUND: There is a need to better understand the depression phenomenon and to clarify why some students become depressed and others don't. The purpose of this study was to compare the prevalence of depressive symptoms among health professions' (HP) students, and to explore the association between socio-demographic factors (e.g. year of study, discipline, gender) and depressive symptoms. METHODS: In this descriptive-analytic, cross-sectional study, stratified proportionate sampling strategy was used to select the study sample during the academic year 2012-2013. The students from four health professions' schools situated within a large, public university located in Riyadh, Saudi Arabia were screened for depressive symptoms using the 21-item Beck Depression Inventory (BDI II). Chi-square test, student t-test and ANOVA were used to compare different categorical variables. RESULTS: The overall response rate was 79.0 %, the highest among dental students 86.1 %, and lowest among nursing (49.7 %). The overall prevalence rate of depressive symptoms was 47.0 %; it was highest among dentistry students (51.6 %), followed by medicine (46.2 %), applied medical sciences (AMS) (45.7 %) and lowest among nursing students (44.2 %). A statistically significant association was found between the presence and severity of depressive symptoms on one hand and the female gender (p = 0.000) and year of study on the other hand. CONCLUSION: This study seems to indicate an alarming rate of depressive symptoms. Female gender, dentistry, the third year for all schools and fifth year for medicine and dentistry have the highest association with depressive symptoms. Future studies may be needed to explore further the reasons and explanations for the variation in the prevalence of depressive symptoms among these groups. The factors that deserve exploration include curricular variables and personal factors such as the students' study skills
Influence of premolar extraction or non-extraction orthodontic therapy on the angular changes of mandibular third molars
Abstract Aim: To compare the angular changes of the third molars relative to the occlusal planeand to the second molar long axis in extraction group and compare these changes with a non extractiongroup.Materials and methods: The study included pre and post treatment panoramic radiographrecords of 90 subjects treated by first premolar extractions and 90 subjects who had been treatedwith non extraction orthodontic therapy (n=90). Two angular variables were measured. Firstly,the angle between the long axis of the third molar and the occlusal plane (M3–OP) and secondly,the angle between the long axis of the third molar and the long axis of the second molar (M3–M2).Data were analyzed by paired and student’s t-test.Result: The analyzed data to assess the changes in the third molar angulation from pretreatmentto post treatment did not vary significantly in both the groups (pdecreased angular values. The M3–OP angular difference was (7.3± 2.45) in extraction group ascompared to (5.85 ± 1.77) in non extraction group. The M3–M2 angular difference of (4.26±3.11) in extraction group and (2.98 ±1.74) in non-extraction group was observedConclusion: Extraction of premolars did not demonstrate considerable changes on the angulationof the third molars. The factors other than premolar extractions may influence the angulationof the third molars.</p

Objective: To assess the occurrence of GERD after bariatric surgery and surgery impact on GERD. Methods: This research employs a cross-sectional study design to investigate the impact of bariatric surgery on Gastroesophageal Reflux Disease (GERD) among individuals who have undergone various types of bariatric surgeries. Results: The study included 302 participants. The most frequent weight among them was more than 96 kg (n= 130, 43%) followed by 76-85 kg (n= 51, 16.9%). The most frequent height among study participants was 1.61-1.70 m (n= 100, 33.1%) followed by 1.51-1.60 m (n= 99, 32.8%). The most frequent body mass index (BMI) value among study participants was more than 35 kg/m2 (n= 126, 41.7%) followed by 25-29.9 kg/m2 (n= 67, 22.2%). The most frequent age among study participants was 26-36 years (n= 104, 34.4%) followed by 15-25 years (n= 83, 27.5%). The most frequent gender among study participants was Female (n= 162, 53.6%) followed by Male (n= 140, 46.4%). Participants were asked about the type of obesity surgery. The most frequent was Gastric sleeve (n=222, 73.5%), followed by Gastric bypass (n=33, 10.9%). Conclusion: Study results showed that most of the study participants are extremely obese according to their BMI. The most common obesity surgery type was a Gastric sleeve followed by a Gastric bypass. The most of participants were a non-smoker. Most of them had weight loss. In addition, most of the study participants had good social connection
Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis
BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study
Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world.
Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231.
Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001).
Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication
Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries
Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
