Effectiveness of Acceptance and Commitment Therapy for Depression, Psychological Well-Being and Feeling of Guilt in 7 - 15 Years Old Diabetic Children

Background: Diabetes imposes restrictions on physical, emotional, and social functioning of children and adolescents. Objectives: The aim of this study was to determine effectiveness of acceptance and commitment therapy (ACT) for depression, psychological well-being and feeling of guilt in 7 - 15 years old diabetic children. Patients and Methods: This was a clinical trial with pre-test and post-test design with control group. The study population consisted of 34 participants selected using convenient sampling out of all 7 - 15 years old patients that referred to the Diabetes Association of Tabriz. They were randomly allocated into two equal groups (experimental and control). The experimental group participated in therapy sessions and the control group did not receive any intervention. The research instruments were reynolds child depression scale (RCDS), eysenck feelings of guilt scale and satisfaction with life scale (SWLS). Results: Multivariate covariance analysis (MANCOVA) showed that the treatment was effective on variables of depression, psychological well-being and feeling guilty in 7 - 15 years old diabetic children (P < 0.001). Conclusions: The aforementioned treatment is effective and suggested to be used in other psychosomatic diseases of children.

Kawasaki Disease and Peripheral Gangrene in Infancy

Introduction: Early diagnosis and treatment of Kawasaki disease as the most common cause of acquired heart disease in childhood, may significantly improve the prognosis. Diagnosing infantile Kawasaki (younger than a year) is difficult because of obscure symptoms; at the same time they are at the higher risk of coronary abnormalities. Case Presentation: We report three infants with prolonged (more than 5 days) fever and peripheral gangrene without any other clinical manifestations of Kawasaki disease. Kawasaki was diagnosed due to dilation of coronary artery and other aortic branches, thrombocytosis, and rising of ESR and CRP. All patients were treated with high dose aspirin, IVIG and pulse therapy with methylprednisolone. Additionally, cytotoxic drugs or infliximab were used for two of them because of severe aneurysms in the aortic branches. All 3 patients received aspirin with anti-platelet aggregation dose and 2 patients heparin as an anti-coagulant agent for longtime. After adequate treatment, peripheral gangrene, arterial dilations and aneurysms improved, but during 12 months follow-up coronary aneurysms did not improve completely. Conclusions: Peripheral gangrene must be regarded as an important sign of infantile Kawasaki disease early treatment of which can prevent severe permanent coronary involvements and sequels.

Autophagy in photodynamic therapy

Macroautophagy (autophagy) is crucial for cell survival during starvation and plays important roles in human diseases. It is a highly conserved intracellular degradation system in eukaryotes for removal and recycling of cytoplasmic components including damaged proteins and organelles to obtain energy. The relationship between cancer and autophagy has been extensively studied in recent years. In cancer and cancer therapy, autophagy acts as a double-edged sword. Photodynamic therapy (PDT) is a kind of tumor therapy applied with a tumor-localizing photosensitizing agent which is followed by activation with the light of a specific wavelength. How much is autophagy involved in photodynamic therapy? The work in this area is still limited.

The interaction between Sertoli cells and luekemia inhibitory factor on the propagation and differentiation of spermatogonial stem cells in vitro

Background: Sertoli cells play a pivotal role in creating microenvironments essential for spermatogonial stem cells (SSCs) self-renewal and commitment to differentiation. Maintenance of SSCs and or induction of in vitro spermiogenesis may provide a therapeutic strategy to treat male infertility. Objective: This study investigated the role of luekemia inhibitory factor (LIF) on the propagation of SSCs and both functions of Sertoli cells on the proliferation and differentiation of these cells. Materials and Methods: SSCs were sorted from the testes of adult male mice by magnetic activated cell sorting and thymus cell antigen 1 antibody. On the other hand, isolated Sertoli cells were enriched using lectin coated plates. SSCs were cultured on Sertoli cells for 7 days in the absence or presence of LIF. The effects of these conditions were evaluated by microscopy and expression of meiotic and post meiotic transcripts by reverse transcriptase polymerase chain reaction. Results: Our data showed that SSCs co-cultured with Sertoli cells in the presence of LIF formed colonies on top of the Sertoli cells. These colonies had alkaline phosphatesase activity and expressed SSCs specific genes. SSCs were enjoyed limited development after the mere removal of LIF, and exhibiting expression of meiotic and postmeiotic transcript and loss of SSCs specific gene expression (p< 0.05). Conclusion: Our findings represent co-culture of SSCs with Sertoli cells provides conditions that may allow efficient proliferation and differentiation of SSCs for male infertility treatment.
