Blended learning for teacher professional learning
LÀrare behöver professionellt lÀrande för att skolresultaten ska förbÀttras. För att det ska göra skillnad för alla elever sÄ behöver alla lÀrare delta i den. Samtidigt visas en brist pÄ organiserat professionellt lÀrande för lÀrare (Skolverket, 2013).
Digitaliseringen skapar nya möjligheter. LÀrande online kÀnnetecknas av att vara flexibel tids- och rumsmÀssigt. NÄgot som kan möta det tidsmÀssiga hinder som skolledare uttrycker (Skolinspektionen, 2015). Forskning, av Means et al. (2009), visar att lÀrande med blended learning; dÀr undervisning och lÀrande i det fysiska rummet kombineras med undervisning och lÀrande online, ger bÀttre effekt Àn lÀrande helt fysiskt respektive helt online. Denna studie har tittat pÄ hur de olika undervisningsmiljöerna i blended learning; fysiskt respektive online, kan tillÀmpas för att skapa förutsÀttningar för ett framgÄngsrikt professionellt lÀrande. Metoden metasyntes har anvÀnts för att sÀtta samman resultat frÄn olika studier i syfte att skapa en samling vetenskapligt grundade rÄd; en best practice att luta sig pÄ vid framtida planering. Studien Àr teoretiskt influerad av ett sociokulturellt perspektiv pÄ lÀrande.
Metasyntesen visar att blended learning kan vara en god form att tillÀmpa. Det Àr tydligt att de bÄda undervisningsmiljöerna; fysiskt och online, Àr viktiga. Vid de fysiska trÀffarna vÄrdas och stÀrks sociala relationer, medan onlinemiljön erbjuder en betydelsefull tids- och rumsmÀssig flexibilitet. FörutsÀttningar för ett framgÄngsrikt professionellt lÀrande med blended learning Àr att strukturella resurser som god IT-miljö och avsatt tid för lÀrandet finns.
Metasyntesen Àr tÀnkt som ett stöd för skolledare och andra beslutsfattare inför planering av framtida professionellt lÀrande för grundskollÀrare.Teachers need professional learning opportunities to improve school results. To have impact for all students, all teachers need to participate. However, there is currently an acknowledged lack of organized professional learning for teachers (Skolverket, 2013).
Technology creates new possibilities. Online learning is known to be flexible in terms of time and space, a feature that can help meet the time-related obstacles that school leaders report (Skolinspektionen, 2015). Research, by Means et al. (2009), shows that blended learning, a method where teaching and learning face-to-face is combined with teaching and learning online, has a better effect then exclusively face-to-face or online approaches. This study has explored how the different teaching environments in a blended learning approach; face-to-face and online, can be used to create successful professional learning opportunities. The method used is research synthesis to combine results from different studies in order to create an overarching account of best practice to draw on during future planning. The study is theoretical influenced by a sociocultural view of learning.
The research synthesis shows that blended learning can be a promising approach. It is clear that both the teaching environments; face-to-face and online, are important. It shows that social relationships are particularly strengthened by face-to-face meetings, while online solutions offer increased flexibility in terms of time and space. The results also show that necessary conditions for successful blended learning initiatives include structural resources such as good ICT and allocated time for learning.
This research synthesis is intended to support school leaders and policymakers in the planning of future teacher professional learning

Efficacy and safety of resveratrol, an oral hemoglobin F-augmenting agent, in patients with beta-thalassemia intermedia
Recently, resveratrol showed induction of ĂÂł-globin mRNA synthesis in human erythroid precursors and reducing oxidative stress in red cells of thalassemia patients in many in vitro studies. We aimed to investigate the efficacy and safety of resveratrol, for the first time, in non-transfusion-dependent beta-thalassemia intermedia (B-TI) in Southern Iran. In this double-blind randomized clinical trial, 54 patients with B-TI were investigated during 6Ă months between October 2016 and March 2017. Patients were randomly allocated into three groups by simple randomization method. Group 1 (hydroxyurea (HU) and placebo, 18 patients), group 2 (resveratrol/piperine and placebo, 16 patients), and group 3(HU and resveratrol/piperine, 20 patients). Primary end point was considered as change in hemoglobin (Hb) levels and need for blood transfusion. Drug safety was considered as a secondary end point. Mean age of the patients was 28.2 ñ 5.6 (18Ăąïżœïżœ42) years. Response rate was not significantly different among the three groups (P > 0.05). Higher percentages of adverse events were detected in groups 2 (31.3) and 3 (25) compared to group 1 (5.6). However, the difference was not statistically significant (P > 0.05). All reported adverse events were gastrointestinal symptoms. Resveratrol showed a similar efficacy with HU in the small population of non-transfusion B-TI patients during a 6-month follow-up. Complications, mostly gastrointestinal, were observed more frequently in resveratrol groups compared to the HU group. Although it was not statistically significant, more attention should be given to safety and efficacy of resveratrol as an oral HbF-augmenting agent.

Bone Markers Status in Gravesâ disease before and after Treatment
"nBackground:  Bone turnover is reported to increase in favor of resorption in overt hyperthyroidism and the rate of resorp­tion is associated with the levels of thyroid hormones. As persistent increase in bone turn over is responsible for accelerated bone loss, patients with Graves' disease may have increased risk for osteoporosis. The aim of this study was to determine relationship between Graves' disease and bone markers."nMethods: The subjects of our study were 31 consecutive untreated GD patients and 37 normal volunteers who were matched on sex proportion and age ranging was diagnosed by suppressed levels of TSH and elevated level of free T3 and free T4 and positive thyroid receptor antibody. Through a clinical trial study executed in endocrinology and metabolism research center, we investigated the relationship between serum osteocalcin & cross-laps with Graves' disease and then kinds of treatment with PTU and methimazole after 8 weeks follow up."nResults: No significant differences in age and sex between patients and controls were found. Significant differences in se­rum bone markers and thyroid hormones were detected between patients and controls before therapy (p< 0.001). After treatment we found a significant improvement and returning to normal range in all serum lab tests. There were not any dif­ferences in the effect of treatment on thyroid hormones and bone markers between two groups."nConclusion: We found close relationship between Graves' disease and bone markers. So that treatment of Graves' disease can improve bone turn over. These findings indicated that early diagnosis and management of Graves' disease can be effec­tive for osteoporosis prevention in these patients
HYPOTHYROIDISM FOLLOWING THYROID SURGERY
Postsurgical hypothyroidism and its incidence has not been fully investigated. In this study, the incidence of hypothyroidism and its possible risk factors at Shariati Hospital was assessed. One hundred and two patients with benign thyroid diseases, who had undergone thyroidectomy, were investigated with regards to thyroid function profile during period of one year after the operation every three months with post-operative sample as the baseline. Hypothyroidism was developed in 36 patients (35.2%) on average 5 ± 3.2 months after surgery. Factors such as increased age, operation type, histopathologic type, underlying disease, lymphocytic infiltration and use of levothyroxine before surgery were associated with the increased incidence of hypothyroidism. It seems that use of indicators such as Graves' disease and lymphocytic infiltration in pathologic specimens should be helpful in projecting the potential occurrence of hypothyroidism in patients undergoing thyroidectomy

Influence of disruption of the acromioclavicular and coracoclavicular ligaments on glenohumeral motion: a kinematic evaluation
Background: Changes to the integrity of the acromioclavicular (AC) joint impact scapulothoracic and clavicular kinematics. AC ligaments provide anterior-posterior stability, while the coracoclavicular (CC) ligaments provide superior-inferior stability and a restraint to scapular internal rotation. The purpose of this cadaveric study was to describe the effect of sequential AC and CC sectioning on glenohumeral (GH) kinematics during abduction (ABD) of the arm. We hypothesized that complete AC ligament insult would result in altered GH translation in the anterior-posterior plane during abduction, while subsequent sectioning of both CC ligaments would result in an increasing inferior shift in GH translation. Methods: Six cadaveric shoulders were studied to evaluate the impact of sequential sectioning of AC and CC ligaments on GH kinematics throughout an abduction motion in the coronal plane. Following an examination of the baseline, uninjured kinematics, the AC ligaments were then sectioned sequentially: (1) Anterior, (2) Inferior, (3) Posterior, and (4) Superior. Continued sectioning of CC ligamentous structures followed: the (5) trapezoid and then the (6) conoid ligaments. For each group, the GH translation and the area under the curve (AUC) were measured during abduction using an intact cadaveric shoulder. Total translation was calculated for each condition between ABD 30° and ABD 150° using the distance formula, and a univariate analysis was used to compare total translation for each axis during the different conditions. Results: GH kinematics were not altered following sequential resection of the AC ligaments. Disruption of the trapezoid resulted in significant anterior and lateral displacement of the center of GH rotation. Sectioning the conoid ligament further increased the inferior shift in GH displacement. Conclusion: A combined injury of the AC and CC ligaments significantly alters GH kinematics during abduction. Type III AC separations, result in a significant change in the shoulderâs motion and may warrant surgical reconstruction to restore normal function
