Does job value boost self-efficacy and protect against burnout among teachers in Oman?

Introduction. The purpose of this study was to examine if the perception of teaching value and a teacher's self-efficacy (SE) are related to burnout. Previous research has shown a strong relation between teachers SE and burnout. Rarely, however, job value has been included in any of the previous studies. Method. A stratified random sample (N =2446) of Omani teachers was drawn. Three measures: Job value, Maslach burnout inventory (MBI) and the teachers' sense of efficacy scale (TSES) were used. Confirmatory factor analysis was performed to test the proposed factor structure of the measures as well as the proposed structural model. Results. The invariance tests proved that the structure of constructs and the relations between constructs were invariant across gender. Job value significantly related to both SE and burnout dimensions. Consistent with predictions, SE of student engagement related to all three burnout dimensions; whereas the other two dimensions of SE didn’t relate to burnout dimensions in the expected direction. Job value and SE explained significant variances in each of the burnout dimensions. Discussion and Conclusion. The results of this study highlight the importance of job value and SE of engaging students as cognitive self-regulatory mechanisms used in the stressful situations like teaching and to help control stress and burnout. Ministry of education, media and socity at large should be aware of the social status of teaching and teachers and provide more respect to the teachers and their job. Such respect would improve the morale of teachers and help them become more efficacious and less exhausted

The Factor structure of the Rosenberg Self-Esteem Scale among school students and university students in Oman

هدفت الدراسة الحالية إلى اختبار البنية العاملية لمقياس روزنبرغ لتقدير الذات، وفحص ما إذا كانت هذه البنية تتساوى لدى عينتين عمريتين. فقد أفادت دراسات عدة أن تقدير الذات ينمو ويتطور ويصبح أكثر واقعية وتمايزًا مع التقدم في العمر. وقد استجاب لمقياس تقدير الذات 365 طالبًا من طلبة المدارس و119 من طلبة الجامعة. يتكون مقياس تقدير الذات لروزنبرغ من 10 فقرات، نصفها تمت صياغته صياغة موجبة، والنصف الآخر تمت صياغته صياغة سالبة. وقد تبين أن مقياس تقدير الذات يتمتع بثبات مقبول لا سيما لدى طلبة الجامعة. وقد تبين أن المقياس يتمتع ببنية عاملية مقبولة لدى كل من العينتين، فقد تشبعت كل فقرات المقياس على عامل تقدير الذات بدرجة جوهرية. إلا أن وجود عامل واحد فقط؛ لم يمثل البيانات بشكل مقبول، فقد كان التطابق ضعيفًا بين العامل الواحد والبيانات. في حين أن وجود عاملين أحدهما موجب والآخر سالب، مثّلا البيانات بدرجة معقولة. ولكن عند اختبار فرضية تساوي المعالم لدى العينتين، اتضح أن المعالم التي تمثل التشبعات كانت متساوية لدى المجموعتين، بينما لم تتساو معالم الثوابت والبواقي والعلاقات بين البواقي. وخلصت الدراسة إلى أن النموذج الأكثر مطابقة للبيانات هو نموذج عامل السمة وعامل الطريقة السالبة في الصياغة، في إشارة إلى تأثير طريقة الصياغة على البنية العاملية، والدرجة التي يفرزها مقياس روزنبرغ. كما تبين الدراسة أهمية الانتباه إلى طريقة صياغة الفقرات عند تفسير الدرجات التي يفرزها هذا المقياس وغيره من المقاييس التي تحوي عبارات موجبة وأخرى سالبة.The aim of this study was to test the structure of Rosenberg Self-Esteem Scale (RSES) and explore if the structure is invariant across school students (n=365) and university students (n=119). Previous research has shown that self-esteem so as other personality traits are developmental in nature; and self-esteem becomes more differentiated and realistic with age. Two samples responded to RSES which has 10 items half of which was written in the positive format and the other half in negative format. RSES showed reasonable internal consistency, especially among university students. Also, the scale produced a reasonable structure among both groups as the items measured the factor substantially. Item loadings were invariant across the two groups. However, other parameters (intercepts, residuals and correlations among residuals) were not invariant indicating that the items measured the trait equally valid for school and university students. However, the level of self-esteem as indicated by item scores was not invariant as school children scored higher than university students in most of the items. The results imply that using negative items has an effect on both the structure and magnitude of self-esteem. Scale developers and users may need to be cautioned when they interpret the resultant scores of scales with positive and negative items

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.

Global economic burden of unmet surgical need for appendicitis

Background: There is a substantial gap in provision of adequate surgical care in many low-and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods: Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results: Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion: For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially

Pooled analysis of WHO Surgical Safety Checklist use and mortality after emergency laparotomy

Background The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery has not been assessed on a global scale. The aim of this study was to evaluate reported checklist use in emergency settings and examine the relationship with perioperative mortality in patients who had emergency laparotomy. Methods In two multinational cohort studies, adults undergoing emergency laparotomy were compared with those having elective gastrointestinal surgery. Relationships between reported checklist use and mortality were determined using multivariable logistic regression and bootstrapped simulation. Results Of 12 296 patients included from 76 countries, 4843 underwent emergency laparotomy. After adjusting for patient and disease factors, checklist use before emergency laparotomy was more common in countries with a high Human Development Index (HDI) (2455 of 2741, 89.6 per cent) compared with that in countries with a middle (753 of 1242, 60.6 per cent; odds ratio (OR) 0.17, 95 per cent c.i. 0.14 to 0.21, P <0001) or low (363 of 860, 422 per cent; OR 008, 007 to 010, P <0.001) HDI. Checklist use was less common in elective surgery than for emergency laparotomy in high-HDI countries (risk difference -94 (95 per cent c.i. -11.9 to -6.9) per cent; P <0001), but the relationship was reversed in low-HDI countries (+121 (+7.0 to +173) per cent; P <0001). In multivariable models, checklist use was associated with a lower 30-day perioperative mortality (OR 0.60, 0.50 to 073; P <0.001). The greatest absolute benefit was seen for emergency surgery in low- and middle-HDI countries. Conclusion Checklist use in emergency laparotomy was associated with a significantly lower perioperative mortality rate. Checklist use in low-HDI countries was half that in high-HDI countries.Peer reviewe

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 &lt; 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

Global variation in anastomosis and end colostomy formation following left-sided colorectal resection

Background End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection. Methods This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associated with colostomy formation versus primary anastomosis were explored using a multilevel, multivariable logistic regression model. Results In total, 1635 patients from 242 hospitals in 57 countries undergoing left-sided colorectal resection were included: 113 (6·9 per cent) from low-HDI, 254 (15·5 per cent) from middle-HDI and 1268 (77·6 per cent) from high-HDI countries. There was a higher proportion of patients with perforated disease (57·5, 40·9 and 35·4 per cent; P < 0·001) and subsequent use of end colostomy (52·2, 24·8 and 18·9 per cent; P < 0·001) in low- compared with middle- and high-HDI settings. The association with colostomy use in low-HDI settings persisted (odds ratio (OR) 3·20, 95 per cent c.i. 1·35 to 7·57; P = 0·008) after risk adjustment for malignant disease (OR 2·34, 1·65 to 3·32; P < 0·001), emergency surgery (OR 4·08, 2·73 to 6·10; P < 0·001), time to operation at least 48 h (OR 1·99, 1·28 to 3·09; P = 0·002) and disease perforation (OR 4·00, 2·81 to 5·69; P < 0·001). Conclusion Global differences existed in the proportion of patients receiving end stomas after left-sided colorectal resection based on income, which went beyond case mix alone

Optimismo y pesimismo de alumnos de educación física y otros: invariabilidad de estructura 1 Resumen Optimism and Pessimism of Physical Education and Non- Physical Education Students: Invariance of Structure Abstract

Introducción. Optimismo y pesimismo son dos constructos psicológicos que juegan un papel significativo en la higiene mental humana y psicológica. Estas dos construcciones están fuertemente correlacionadas, pero negativamente. Optimismo y pessimisim puede estar influenciada por la cultura. El presente estudio intenta para poner a prueba la estructura del optimismo y pesimisimo a través de dos países: Emiratos Árabes Unidos y Omán. Además, los estudiantes de educación física fueron comparados con los estudiantes de educación no-física. Método. Estudiantes universitarios de SQU en Omán (n = 103) y el UAEU (n = 200) participaron en el estudio. La muestra SQU fue principalmente de estudiantes de educación física (hombres = 60, mujeres = 43). El instrumento consiste en treinta ítems tipo Likert. El optimismo y el pesimismo se evaluó a través de 15 items, cada uno. Resultados. El análisis factorial exploratorio identificó claramente dos factores más que un factor bipolar. El número de factores (2), el patrón de cargas de cada factor , las correlaciones de los factores y singularidad eran invariables a través de Educación Física (PE) y las muestras de no P.E (NPE) . El MANOVA reveló que los sujetos educación física se mostraron más optimistas que los que no eran deeducación física. Sin embargo, no se encontraron diferencias significativas en el pesimismo entre los PE educación física y los que eran de educación física. Discusión y Conclusiones. Los resultados revelaron que optimismo y pesimismo pueden influidas por el entorno inmediato, así como el tipo de estudio. En cuanto a la estructura, el instrumento fue tan válida y fiable en Omán y en los Emiratos Árabes Unidos, ya que era válido y fiable en Kuwait, donde se desarrolló el instrumento original y estandarizado
