Quality of life among patients with beta-thalassemia major in Shahrekord city, Iran
Background and aims: Nowadays introduction of regular blood transfusion therapy has
obviously improved the life expectancy of patients with thalassemia. However, these
patients face with newer challenges which influence their quality of life (QoL). In this
study, the aim of this study was to measure QoL among patients with β-thalassemia
major (β-TM).
Methods: A cross-sectional study was done at the thalassemia centre of Shahrekord
University of Medical Sciences. All the forty patients with β-thalassemia which were
more than 12 years old referred to blood transfusion and participated in this study. Then,
they were asked to fill out the Short Form Health Status Survey (SF-36) questionnaire.
The questionnaire evaluates 8 health areas including physical functioning (PF), rolephysical
(RP), bodily pain (BP), general health (GH), vitality (VT), social functioning
(SF), role-emotional (RE) and mental health (MH). The scores of each participant were
calculated and data were analyzed using SPSS.
Results: There were 18 men and 22 women, and the mean age was 21.69±5.74 years
(range 12-38). No significant difference was seen in QoL between men and women
(68.72±19.79 versus 67.47±18.80, P=0.84). The mean±SD score of PF, RP, BP, GH, VT,
SF, MH was 80.5±16, 83.75±29.17, 71.94±24.22, 57.48±23.93, 54.36±22.51,
68.94±23.37, 66.33±36.04 and 58.51±23.68, respectivly. No significant differences were
detected in all mentioned scores between men and women (P>0.05).
Conclusion: Although most of the participants had suitable physical functioning,
thalassemia had a negative effect on emotional role, social functioning and mental health
of patients. It shows the importance of psychosocial supports for these patients
Cannabinoid receptors contribute to astroglial Ca2+-signalling and control of synaptic plasticity in the neocortex
Communication between neuronal and glial cells is thought to be very important for many brain functions. Acting via release of gliotransmitters, astrocytes can modulate synaptic strength. The mechanisms underlying ATP release from astrocytes remain uncertain with exocytosis being the most intriguing and debated pathway. We have demonstrated that ATP and D-serine can be released from cortical astrocytes in situ by a SNARE-complex-dependent mechanism. Exocytosis of ATP from astrocytes can activate post-synaptic P2X receptors in the adjacent neurons, causing a downregulation of synaptic and extrasynaptic GABA receptors in cortical pyramidal neurons. We showed that release of gliotransmitters is important for the NMDA receptor-dependent synaptic plasticity in the neocortex. Firstly, induction of long-term potentiation (LTP) by five episodes of theta-burst stimulation (TBS) was impaired in the neocortex of dominant-negative (dn)-SNARE mice. The LTP was rescued in the dn-SNARE mice by application of exogenous non-hydrolysable ATP analogues. Secondly, we observed that weak sub-threshold stimulation (two TBS episodes) became able to induce LTP when astrocytes were additionally activated via CB-1 receptors. This facilitation was dependent on activity of ATP receptors and was abolished in the dn-SNARE mice. Our results strongly support the physiological relevance of glial exocytosis for glia–neuron communications and brain function
Effect of aromatherapy on anxiety and pain in patients undergoing cholecystectomy
Background and aims: Aromatherapy means application of concentrated essences from different types of plants (such as flowers) for treatment of different types of diseases. Aromatherapy works for stress, anxiety, psychosomatic problems, muscular and rheumatic pains, gastrointestinal problems, menopause and postpartum depression. The present study aimed to study the effect of aromatherapy on anxiety and pain in patients undergoing cholecystectomy. Methods: This is a single-blinded clinical trial study which was conducted with participation of 60 patients undergoing cholecystectomy in Sina Treatment Center, Tabriz, Iran in 2012-2013. The patients were randomly assigned using table of random numbers. In intervention group, the patients inhaled 10 drops of rose water with 12 concentration for three minutes 8 and 16 hours after surgery. For control group, routine care continued in the ward. The data were analyzed by SPSS using descriptive statistics and inferential statistics, one-way ANOVA and post hoc Tukey’s test). Results: Comparison of changes in pain and anxiety scores between the two group indicated that the developed changes in pain and anxiety level (mean relief of pain and anxiety 8 and 16 hours after surgery) in the aromatherapy group was significantly different from the control group (P<0.001) and the level of relief of pain and anxiety was higher in aromatherapy group than the control group 8 and 16 hours after surgery (P<0.001). Conclusion: The findings indicated the positive effect of rose water-mediated aromatherapy on relief of pain and anxiety in patients 8 and 16 hours after surgery. Aromatherapy could be used as a cheap, noninvasive, complication-free, and non-pharmacologic nursing care
Serobiochemical Alterations in Subclinically Affected Dromedary Camels with Trypanosoma Evansi in Iran
The aim of this study was to investigate the effects of subclinical Trypanosoma evansi infection on serum biochemical parameters of dromedary camels. Jugular vein blood samples were taken weekly for three successive weeks from 110 apparently healthy male camels and examined for the presence of trypomastigote form of T. evansi in blood smears. The parasite was seen in 17 (15.45%) blood smears. Various serum biochemical parameters i.e., glucose, urea, cholesterol, triglyceride, calcium, magnesium, sodium, potassium, phosphorus, total protein, albumin, triiodothyronine (T3), thyroxine (T4), cortisol, and activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and creatine kinase (CK) were determined. Infected camels had significantly lower serum glucose, T3 and T4 concentrations (P<0.05), and significantly higher triglycerides concentration and ALT activity (P<0.05). It was concluded that subclinical infection of camels with T. evansi can also affect some biochemical parameters
