The role of peer support education model on the quality of life and self-care behaviors of patients with myocardial infarction

ObjectiveThis study aimed to assess the effect of peer education on the quality of life and self-care behaviors of patients with myocardial infarction.MethodsIn this clinical trial, 70 patients with myocardial infarction meeting the inclusion criteria were assigned to experimental (n = 35) or control (n = 35) groups using block randomization. Patients in the intervention group received two one-hour training sessions on the third day after myocardial infarction during the CCU stay along with routine care. Education intervention was performed by peers. The control group will follow routine care. All patients selected were assessed using McNews' quality of life questionnaire and Miller self-care questionnaire, respectively before the intervention and also one month after discharge. Chi-square and t-test were used to analyze the data.ResultsAfter the intervention, the mean of quality of life and the mean score of self-care behaviors in the experimental group were significantly higher compared to the control group.ConclusionsAccording to the results, to improve the quality of life and promote the self-care behaviors in such patients, using peer education along with healthcare professionals is recommended.Practice ImplicationThis patient education approach had a significant impact on quality of life and self-care behavior.     

Aberrant p16 methylation, a possible epigenetic risk factor in familial esophageal squamous cell carcinoma

Aim. Detection of methylation in the p16 gene, an inhibitor of cyclin D-dependent protein kinase, as a new tumor marker for early detection of esophageal squamous cell carcinoma (ESCC) in DNA derived from blood and serum. Method. A large family with clustering of ESCC was assessed in Khorasan province in northeastern Iran. The family had three histologically proven cases of ESCC in two consecutive generations and several other deceased cases with histories of ESCC. DNA from blood of 28 living family members in three consecutive generations, 30 sporadic ESCC cases (from serum, blood, and tumor tissues), and 30 healthy volunteers (from blood) were examined for the methylation status of p16 promoter using methylation-specific PCR (MSP). Results. Aberrant p16 promoter methylation was found in 64.3% (n=28) of ESCC family members and none (n=30) of our normal volunteers. Five of the 28 family members with esophageal cancer symptoms had negative endoscopy results for ESCC, while four of these members had p16 hypermethylation in their blood. The family members with negative endoscopy and positive p16 promoter methylation are being monitored closely for signs of ESCC development through regular check-ups and chromoendoscopies. In sporadic ESCC in northeastern Iran, 73.3% (n=30) of tumor tissue samples had p16 hypermethylation. Serum and blood samples from the same patients showed p16 hypermethylation in 26.6% and 43.3% of the samples, respectively. Conclusion. Aberrant p16 methylation may be a valuable diagnostic tool as a tumor marker for the early identification of individuals in high risk ESCC families.

Randomized controlled trial of aripiprazole versus risperidone for the treatment of amphetamine-induced psychosis

Background: Lifetime prevalence of amphetamine-induced psychotic disorder is reported as being up to 23% for methamphetamine (MA) abusers. Approximately 25% of those with a baseline DSM-IV diagnosis of substance-induced psychosis are diagnosed with primary psychosis at one-year follow-up. Evidence on the treatment of amphetamine psychosis is very limited. Objectives: To investigate the efficacy of risperidone versus aripiprazole in treatment of amphetamine-induced psychotic symptoms. Methods: In a double-blind study, 45 participants were randomly allocated to either aripiprazole 15?mg or risperidone 4?mg daily over a six-week trial. Positive and negative symptoms of psychosis were assessed using the Scale for Assessment of Negative Symptoms (SANS) and the Scale for Assessment of Positive Symptoms (SAPS) at baseline and completion of the trial. Results: SANS and SAPS scores decreased significantly in both groups. Mean SAPS score reduction in risperidone and aripiprazole group was 16.20 and 10.80, respectively, after trial course (p?p?=?0.08). Conclusions: Both aripiprazole and risperidone were effective for patients diagnosed with amphetamine-induced psychotic disorder. However, risperidone had the greater effect on positive psychotic symptoms while patients with negative symptoms may respond better to aripiprazole. There is a case for further studies evaluating the efficacy of atypical antipsychotics in this disorder.     

Development of hydrophobic reduced graphene oxide as a new efficient approach for photochemotherapy

Nowadays, chemotherapy is one of the crucial and common therapies in the world. So far, it has been revealed to be highly promising, yet patients suffer from the consequences of severe negative medical dosages. In order to overcome these issues, the enhancement of photothermal chemotherapy with reduced graphene oxide (rGO) as a photothermal agent (PTA) is widely utilised in current medical technologies. This is due to its high near-infrared region (NIR) response, in vitro or in vivo organism biocompatibility, low risk of side effects, and effective positive results. Moreover, rGO not only has the ability to ensure that selective cancer cells have a higher mortality rate but can also improve the growth rate of recovering tissues that are untouched by necrosis and apoptosis. These two pathways are specific diverse modalities of cell death that are distinguished by cell membrane disruption and deoxyribonucleic acid (DNA) disintegration of the membrane via phosphatidylserine exposure in the absence of cell membrane damage. Therefore, this review aimed to demonstrate the recent achievements in the modification of rGO nanoparticles as a PTA as well as present a new approach for performing photochemotherapy in the clinical setting.

rGO of QD-rGO nanocomposite could absorb and convert into heat when harvested under NIR radiation, resulting cell death with reduction of fluorescence.
