Psychometric Properties of the Persian Generalized Trust Scale: Confirmatory Factor Analysis and Rasch Models and Relationship with Quality of Life, Happiness, and Depression
Get PDFThe psychometric properties of the Generalized Trust Scale (GTS) are well established. Furthermore,previousstudieshavefoundthattheGTSispositivelyassociatedwithbetter mental health and lower distress, and the literature finds that trust is good for mental health. However, current literature does not have any psychometric evidence concerning the Persian GTS. This study translated the GTS into Persian and validated its psychometric properties. After translating the GTS into Persian using robust and standardized translation procedure, 1200 Iranians (mean age=34.83 years; 583 [48.6%] males) completed the GTS, along with the Hospital Anxiety and Depression Scale (HADS), Short Form-12 (SF-12), and Oxford Happiness Questionnaire Short Form (OHQ-SF). The factor structure of Persian GTS was confirmed by a unidimensional model with a method factor (comparative fit index=0.998; Tucker-Lewis index=0.992). The unidimensional model was also supported by Rasch analysis (mean square=0.75 to 1.31). Other properties of the Persian GTS were satisfactory. More specifically, test-retest reliability was good (intraclass correlational coefficient=0.865), internal consistency was good (α=0.881), and concurrent validity was supported (standardized β=−0.086 with depression in the HADS [p=0.045];=−0.162 with anxiety in the HADS [p<0.001];= 0.077 with mental component score in the SF-12 [p=0.044]; =0.624 with OHQ-SF [p<0.001]).Thesix-itemPersianGTShas promisingpsychometricpropertiesand can be an effective measure to assess trust among Iranians

TheEffectofUsingOliveOilandFishOilProphylactic Dressings on Heel Pressure Injury Development in Critically Ill Patients
Get PDFIntroduction and Aim: Prevention of pressure injuries in patients hospitalized in intensive care units is significantly important. Therefore, in the present study, the effect of using olive oil and fish oil prophylactic dressings on the development of heel pressure injuries was investigated. Methods: The present study was a clinical trial conducted in the intensive care unit of Shahid Beheshti Hospital, in Yasuj. Fifty patients, who were at moderate to high risk of pressure injuries development, were randomly divided into two groups based on the mean score of the Braden scale. In one group, patients’ heels were dressed using olive oil prophylactic dressing, and in the other group, patients’ heels were dressed using fish oil prophylactic dressing. The dressings were changed 3 times a day. Collected data were then analyzed using SPSS v16. Results: No significant difference was determined in demographic variables among the two groups (p<0.05). In terms of the development of heel pressure injuries, none of the patients in the olive oil and fish oil groups had pressure injuries. Conclusion: Therewerenostatisticallysignificantdifferencesineithertreatmentgrouprelated to heel pressure injuries outcomes during the 7 days observed in the study. Additionally, both dressings had the same effects. Further studies are recommended in this regard

Comparison of the effects of sertraline and L-carnitine on intradialytic hypotension; a double blind clinical trial
Get PDFIntroduction: Although some studies have reported the positive effect of sertraline and
L-carnitine on intradialytic hypotension (IDH), a common complication of dialysis, however
the results are controversial.
Objectives: The aim of this study was to compare the effects of sertraline and L-carnitine on
blood pressure in patients with chronic renal failure who were undergoing dialysis.
Patients and Methods: This double-blind clinical trial was conducted on 32 hemodialysis
patients who suffered from IDH in more than 50% of dialysis sessions. Patients were randomly
divided into two groups of sertraline (50 mg daily) and L-carnitine (1000 mg daily), with 16
patients in each group. Duration of treatment was four weeks, then patients were followed up for
additional three weeks. The changes in patients’ blood pressure were monitored in each group
and the results compared between the two groups.
Results: Of all, 18 patients (56%) were female, 14 patients (44%) were male, and their mean
(SD) age was 60±15 years. At the end of the study, mean systolic blood pressure (SBP), mean
diastolic blood pressure (DBP), and mean arterial pressure (MAP) were significantly increased
in both the sertraline and L-carnitine groups (P<0.05). In addition, nadir SBP, nadir DBP,
and nadir MAP in each group were significantly increased compared to pre-treatment period
(P<0.001). An increase of more than 5 mm Hg in SBP, DPB, and MAP was observed in half of
the subjects in the sertraline group and more than two-thirds of the patients in the L-carnitine
group, however there was no significant difference between the two groups (P>0.05).
Conclusion: The findings of this study showed that the administration of sertraline or L-carnitine
for one month could significantly increase SBP, DBP, MAP, and nadir blood pressures in dialysis
patients suffering from IDH during dialysis sessions because there was no significant difference
between the two drug
Synthesis of immobilised Ni-doped TiO2 nanoparticles through hydrothermal route and their efficiency evaluation in photodegradation of formaldehyde
Get PDFThe aim of the present study was to synthesis Ni-doped TiO2 nanoparticles (NPs) in order to evaluate their effectiveness in photocatalytic
degradation of formaldehyde in the aqueous phase. The Ni-doped
TiO2 NPs were synthesised using a mild hydrothermal method. They
were then immobilized on glass plates by the calcination method.
Characterisation of Ni-doped TiO2 NPs was also carried out using
scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses. The SEM images showed the uniform distribution of assynthesised NPs on the surface of glass plates, with multidimensional
crystalline structures. The results indicated that increasing the dopant
weight ratio to 0.7% enhanced the photocatalytic degradation efficiency of formaldehyde; however, a further increase in the dopant
weight ratio reduced the process efficacy. According to the results,
increasing the initial pH from acidic and neutral to alkaline conditions
decreased the efficacy of the process. Furthermore, the results showed
that increasing the amount of nanocatalyst and decreasing the initial
concentration of formaldehyde favoured the photocatalytic degradation of formaldehyde

Evidence for hyperprolactinemia in migraineurs: a systematic review and meta-analysis
Get PDFBackground One of the hypothalamus-pituitary axis hormones which may play a crucial role in pathophysiology of migraine is
prolactin which is secreted from anterior pituitary gland and synthesized by various immune system cells as well. Whether
prolactin blood levels can affect the migraine pathogenesis is an open question. Therefore, investigating prolactin circulatory
levels in migraineurs may pave the way to underpin the mechanisms of migraine pathophysiology at biochemical levels. In the
current investigation, the prolactin blood levels in the migraine subjects were investigated using systematic review and metaanalysis.
Methods Using online and specialized biomedical databases including Google Scholar, Medline, Pubmed, Pubmed Central,
Embase, and Scopus, without the beginning date restriction until Feb 2019, the systematic review retrieved 11 publications in this
systematic review after fulfilling for the inclusion and exclusion criteria. For heterogeneity, extent calculation statistical testing
was applied. In the present study, the levels of circulatory prolactin in migraineurs assessed using standardized mean difference
(SMD) as the effect size.
Results Q quantity and I

% statistic index showed a high heterogeneity in the 13 selected publications (188.370 and 92.568,
respectively) and random-effects model was chosen for further analyses. The meta-analysis on a total number of 460 migraineurs
and 429 healthy controls found that the weighted pooled SMD for the effects of prolactin blood concentrations on migraine
pathogenesis was as follows: SMD = 1.435 (95% confidence interval, 0.854–2.015).
Conclusion The current investigation presents evidence that prolactin blood levels are higher in migraineurs than healthy
subjects
