Revealing New Prospects: Antipsychotic Drugs Exert Anti-Tumor Effects against Gastric Cancer through Inducing Apoptosis.

BACKGROUND AND OBJECTIVE: Globally, Gastric Cancer (GC) ranks as the fifth leading cause of cancer-related deaths. GC is a multifaceted malignancy with diverse etiologies; however, understanding the shared molecular mechanisms can aid in discovering novel targeted therapies for GC. This study has employed a drug repositioning approach to explore new drug candidates for treating GC. METHODS: The human GC cell lines AGS, MKN-45, and KATO-III were treated with different concentrations of dopamine, cabergoline, thioridazine, and entacapone to determine effective doses and IC50 values. In vitro, cytotoxic activity on cancer cell lines was screened based on dose/time using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Quantitative Reverse Transcriptase Polymerase Chain Reaction (qRT-PCR) was used to measure the mRNA expression of B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), and Proliferating Cell Nuclear Antigen (PCNA) in each group. The percentage of apoptotic cells was evaluated using Annexin V/PI staining. RESULTS: Dopamine, cabergoline, thioridazine, and entacapone elicited cytotoxic effects on AGS and KATO-III cells in a dose-dependent manner and elevated the percentage of Annexin V-positive cells, suggesting the occurrence of apoptosis. The expression of Bcl-2 and PCNA was significantly decreased, whereas the expression of Bax was considerably increased in the AGS and KATO-III cells compared to that in the blank group (p < 0.05); however, no similar effect was observed in MKN-45 cells. CONCLUSION: Through in vitro experiments, this study provides evidence that the antipsychotic drugs cabergoline, dopamine, thioridazine, and entacapone can inhibit gastric cancer growth in AGS and KATO-III cells. These findings suggest that these drugs could be repurposed as novel therapeutic agents for the treatment of gastric cancer.

Effect of Melissa officinalis on Chemotherapy-Induced Peripheral Neuropathy in Cancer Patients: A Randomized Trial.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a significant cancer treatment side effect that can influence both quality of life and treatment course. Melissa Officinalis (MO), due to its high content of flavonoids, has antioxidant, anti-inflammatory, and neuroprotective properties.  Materials and Methods: The cancer patients diagnosed with CIPN attended a referral center in Sari (Iran). The hydroalcoholic extract of MO leaves was extracted by the maceration method. The control group received a placebo along with gabapentin as the standard treatment, and the intervention group received 500 mg Melissa officinalis 2 times daily for 3 months plus gabapentin. Patients were evaluated at the baseline and 3 months later, according to Common Terminology Criteria for Adverse Effects (CTCAE) and EORTC QLQ-C30 (Integrated System for Quality of Life Assessment).  Results: A total of 40 patients were considered as group D (intervention group), and 35 patients completed the study. Out of 40 subjects in the placebo group (P), 3 patients could not tolerate the drug due to gastrointestinal disturbances. The final values of CTCAE showed a statistically significant difference (p=0.010). Indicators related to the quality of life in both groups showed a significant improvement. In the intervention group, the pain perception and diarrhea experience were significantly reduced. Conclusion: Quality of life indicators were improved by prescribing gabapentin with and without Melissa officinalis. The addition of Melissa officinalis to the chemotherapy regimen may improve diarrhea and pain perception.

Lung cancer vaccination from concept to reality: A critical review of clinical trials and latest advances.

Lung cancer is a highly lethal malignancy that poses a significant burden on public health worldwide. There have been numerous therapeutic approaches, among which cancer vaccines have emerged as a promising approach to harnessing the patient's immune system to induce long-lasting anti-tumor immunity. The current study aims to provide an overview of cancer vaccination in the context of lung cancer to establish a clearer landscape for lung cancer treatment. To provide a comprehensive review, we not only gathered the published studies of lung cancer vaccination and discussed their effectiveness and safety profile but also analyzed all the relevant clinical trials registered on www.clinicaltrials.gov until March 2024. We demonstrated all utilized vaccine platforms along with having a glance at novel technologies such as mRNA vaccines. The present review discussed the challenges and shortcomings of lung cancer vaccination, as well as the way they could be managed to pave the way for reaching the most optimized vaccine formulation.

Evaluation of mRNA Expression of CD244 and Its Adapter Molecules in CD8+ T Cells in Acute Leukemia.

Background: This study investigated the role of the immune-checkpoint receptor (ICR), CD244, and its adapter molecules, in CD8+ T cells in acute leukemia. Methods: Blood samples were obtained from 21 acute lymphoblastic leukemia (ALL) and 6 acute myeloid leukemia (AML) patients and 20 control subjects. Relative gene expression of CD244, immune receptor tyrosine-based switch motif-associated protein (SA), EWS/FLI1-activated transcript 2 (EAT-2), and LncRNA-GSTT1-AS1 were evaluated using quantitative reverse transcription polymerase chain reaction. Results: Expression of CD244, SAP, and EAT-2 were significantly lower in CD8+ T cells from ALL patients than those from control subjects. Interestingly, the expression of SAP was much lower than that of CD244, indicating a lower ratio of SAP to CD244. Also, SAP expression was significantly lower in AML patients compared to the control group. Expression of LncRNA-GSTT1-AS1 showed no significant difference in ALL and AML patients compared to control subjects. Conclusion: The low SAP/CD244 expression ratio in CD8+ T cells in ALL suggests an inhibitory role for CD244 in ALL.

Investigation of Expression Profile of Placenta-specific 1 (PLAC1) in Acute Myeloid and Lymphoid Leukemias.

Background: Placenta-specific 1 (PLAC1) is one of the cancer-testis-placenta antigens that has no expression in normal tissue except placenta trophoblast and testicular germ cells, but is overexpressed in a variety of solid tumors. There is a lack of studies on the expression of PLAC1 in leukemia. We investigated expression of PLAC1 in Acute Myeloid Leukemia (AML) and Acute Lymphoblastic Leukemia (ALL). Methods: In this study, we investigated expression pattern of PLAC1 gene in peripheral blood and bone marrow mononuclear cells of newly-diagnosed patients with AML (n=31) and ALL (n=31) using quantitative real-time PCR. Normal subjects (n=17) were considered as control. The PLAC1 protein expression in the samples were also detected using western blotting. Results: Our data demonstrated that PLAC1 transcripts had 2.7 and 2.9 fold-change increase in AML and ALL, respectively, compared to normal samples. PLAC1 transcript expression was totally negative in all studied normal subjects. Level of PLAC1 mRNA expression in ALL statistically increased compared to normal samples (p=0.038). However, relative mRNA expression of PLAC1 in AML was not significant in comparison to normal subjects (p=0.848). Furthermore, relative mRNA expression of PLAC1 in AML subtypes was not statistically significant (p=0.756). PLAC1 gene expression showed no difference in demographical clinical and para-clinical parameters. Western blotting confirmed expression of PLAC1 in the ALL and AML samples. Conclusion: Considering PLAC1 expression profile in acute leukemia, PLAC1 could be a potential marker in leukemia which needs complementary studies in the future.

Relative Expression of BATF and CD112 in PBMC of Patients with Chronic Lymphocytic Leukemia.

OBJECTIVE: BATF, as a transcription factor, and CD112, as a receptor for TIGIT, are involved in T-cell exhaustion. We investigated BATF and CD112 gene expression in the peripheral blood mononuclear cells from CLL patients and healthy subjects. METHODS: In a case-control study, 33 patients with CLL and 20 sex- and age-matched healthy individual were enrolled. Diagnosis and classification of patients was done according to immunophenotyping via flow cytometry and RAI staging system, respectively. Relative mRNA expression of BATF and CD112 was measured using qRT-PCR. RESULT: Our results showed that the expression of BATF and CD112 in CLL samples were significantly decreased in comparison those of the healthy controls (P = 0.0236 and P = 0.0002, respectively). CONCLUSION: These findings suggest the role of BATF and CD112 not only as a role in T cell exhaustion, but in effector differentiation program in CLL, which warrants further studies in future.

Dopamine receptors gene overexpression in the microenvironment of invasive gastric cancer and its potential implications.

BACKGROUND: Gastric cancer (GC) is the fifth most common cancer worldwide and the most commonly diagnosed cancer in Iran. The nervous system provides proximity to tumor cells by releasing neurotransmitters such as dopamine and presenting them to the corresponding receptor-bearing tumors. While nerve fibers infiltrate the tumor microenvironment, little is known about the expression levels of dopamine (DA), dopamine receptors (DRs), and catechol-O-methyltransferase (COMT) in GC patients. METHODS: DRs and COMT expression were analyzed in 45 peripheral blood mononuclear cells (PBMCs) and 20 paired tumor and adjacent tissue of GC patients by quantitative polymerase chain reaction. DA was measured in plasma specimens using enzyme-linked immunosorbent assay. Protein-protein interaction analysis was carried out to identify GC-related hub genes. RESULTS: Increased expression of DRD1-DRD3 was found in tumor specimens compared with adjacent non-cancerous specimens (P < 0.05). A positive correlation was found between DRD1 and DRD3 expression (P = 0.009); DRD2 and DRD3 expression (P = 0.04). Plasma levels of dopamine were significantly lower in patients (1298 pg/ml) than in controls (4651 pg/ml). DRD1-DRD4 and COMT were up-regulated in PBMCs of patients compared with controls (P < 0.0001). Bioinformatic analyses showed 30 hub genes associated with Protein kinase A and extracellular signal-regulated kinase signaling pathways. CONCLUSIONS: The findings indicated dysregulation of DRs and COMT mRNA expression in GC and suggest that the brain- gastrointestinal axis may mediate gastric cancer development. Network analysis revealed that combination treatments could be considered for optimizing and improving the precision treatment of GC.

Molecular Imaging of HER2 Expression in Breast Cancer patients Using the [99mTc] Tc-Labeled Small Peptide.

PURPOSE: The accurate determination of human epidermal growth factor receptor 2 (HER2) status can predict response to treatment with HER2-targeted therapy for HER2-positive breast cancer patients. [99mTc]Tc-HYNIC-(Ser)3-LTVPWY ([99mTc]Tc-HYNIC-LY) is a small synthetic peptide molecule targeting of the HER2 receptor. This clinical study evaluated the pharmacokinetic, dosimetry, and efficacy of [99mTc]Tc-HYNIC-LY for determining the HER2 status in primary breast cancer patients. MATERIALS AND METHODS: In total, 24 women with suspected primary breast cancer received an intravenous injection of approximately 20 µg (∼740 MBq) of [99mTc]Tc-HYNIC-LY. In the first 3 patients, blood levels of radioactivity were analyzed for pharmacokinetic evaluation and planar gamma camera imaging was conducted at 30 min and 1, 2, 4, and 24 hour after injection for dosimetry assessment. In the last 21 patients, planar imaging was performed at the baseline, as well as 1, 2, 3, and 4 hour, followed by single-photon emission computed tomography (SPECT) imaging after 4 hour to evaluate the tumor-targeting potential in primary lesions. RESULTS: Injection of [99mTc]Tc-HYNIC-LY was safe and well tolerated. Fast blood clearance provided high-contrast HER2 imaging within 1 to 4 hour. The highest absorbed radiation dose was found for kidneys (6.78E-03 ± 2.62E-04 mSv/MBq), followed by the heart (3.73E-03 ± 1.98E-04 mSv/MBq). The [99mTc]Tc-HYNIC-LY peptide was able to detect HER2 status in primary tumors at an acceptable level. CONCLUSION: The findings of this study indicated that [99mTc]Tc-HYNIC-LY SPECT is safe and feasible for the identification of HER2-positive lesions in primary breast cancer patients, and may provide an accurate and non-invasive modality for guiding HER2 targeted therapy.

Can we consider soluble herpes virus entry mediator (sHVEM) as a tumor marker?

Background: Immune checkpoint molecules have critical roles in directing immune responses into co-inhibitory and co-stimulatory signals. Herpes virus entry mediator (HVEM) is a receptor of tumor necrosis factor receptor superfamily with unique features due to its interaction with both inhibitory and stimulatory ligands. The aim of this study was to measure the serum level of the soluble form of HVEM in patients with gastric, colorectal and breast cancers and evaluating its diagnostic and prognostic value. Methods: The concentration of the soluble HVEM (sHVEM) was determined in the serum of 36 patients with breast cancer, 50 patients with colorectal cancer and 59 patients with gastric cancer using ELISA method. Moreover, 50 healthy donors (HD) as well as 31 patients with non-ulcer dyspepsia (NUD) were used as control groups. The patients' samples were obtained from the Biobank of Cancer Research Center, Mazandaran University of Medical Sciences, Sari, Iran. Results: The level of sHVEM was significantly higher in patients with gastric (P=0.001) and breast cancer (P=0.01) than in control groups (HD). The higher level of sHVEM was observed in colorectal cancer patients in comparison with HD group, although it was not significant. Moreover, the elevated level of sHVEM was shown to be higher significantly in stage III and IV compared to stage I and II in breast cancer (P=0.03). Similar finding was detected in gastric and colorectal cancers, but not to be statistically significant. Conclusion: The results of the present study suggest that the serum level of sHVEM may be considered as a promising indicator for diagnosis as well as evaluating the progression of cancers such as gastric, breast and colorectal cancers.

Association between Serum Progastrin Biomarker Level and Gastric Cancer.

BACKGROUND AND OBJECTIVE: gastric cancer is the fifth most prevalent cancer and the fourth cause of death because of cancer. In Iran, northern and northwestern regions are considered gastric cancer hot spots. Identifying serum biomarkers could be helpful in early diagnosis of patients with gastric adenocarcinoma (GAC). Increase in progastrin level has been reported in different cancers. Given the diagnostic value of this biomarker, this study aimed to determine the diagnostic role of progastrin serum biomarker in patients with gastric cancer. METHODOLOGY: In this case-control study, forty patients with gastric cancer who were diagnosed by endoscopy and pathologic findings and visited Mazandaran Comprehensive Cancer Center. The participants had received no treatment yet and entered this study. The participants in case group were compared with the control group including forty-two individuals with no history of gastrointestinal cancer in their first-degree relatives and visiting the lab for routine tests. Progastrin serum level was assessed using ELISA kit. The Kruskal-Wallis test and Mann Whitney test, both non-parametric) were used for statistical analysis and the relation between the variables was examined using Pearson's correlation coefficient at 95% confidence level in SPSS 16. FINDINGS: In this study, progastrin serum level was significantly higher in patients with gastric cancer compared with normal participants (P = 0.035). Progastrin serum level had no significant relation with tumor clinicopathologic parameters (p-value > 0.05). CONCLUSION: Increase in progastrin may be utilized as a predictive factor for gastric cancer.

Tim-3 and PD-1 blocking cannot restore the functional properties of natural killer cells in early clinical stages of chronic lymphocytic leukemia: An in vitro study.

Background: Programmed death-1 (PD-1) and T-cell immunoglobulin- and mucin-domain-containing molecule-3 (Tim-3) are two major immune checkpoint receptors expressed on immune cells and their expression is related to the exhaustion phenotype. In the present in vitro study, blocking of PD-1 and Tim-3 molecules was performed on isolated natural killer (NK) cells from patients with chronic lymphocytic leukemia (CLL) to restore their functional properties. Materials and Methods: NK cells fraction was positively isolated from fresh peripheral blood of 18 CLL patients, treated with anti-PD-1 and anti-Tim-3 blocking monoclonal antibodies and co-cultured with K562 target cells to evaluate their apoptosis induction by Annexin V-PI method. Blocked NK cells were also incubated with anti-CD107a antibody to assess their degranulation properties by flow cytometry. The level of secreted tumor node factor-alpha (TNF-α) and interferon-gamma (IFN-γ) by NK cells was also measured by ELISA. Results: Our results showed similar functional properties in terms of degranulation and apoptosis of K562 target cells by isolated NK cells from CLL patients in PD-1/Tim-3 blocked and control groups. It was also shown that blocking of PD-1 and Tim-3 could not improve the production of pro-inflammatory TNF-α and IFN-γ cytokines by isolated NK cells from CLL patients. Conclusion: Altogether, our results indicated that pretreatment of NK cells with anti-PD-1 and anti-Tim-3 blocking antibodies in CLL patients at early clinical stages cannot improve their functional properties. Besides many other malignancies, the application of checkpoint inhibitors in CLL needs more investigations and complementary studies.

Combined Blockade Of PD-1 and TIGIT is not Sufficient to Improve the Function Of CD8+ T-Cells in Chronic Lymphocytic Leukemia.

BACKGROUND AND OBJECTIVE: Blockade of immune checkpoint receptors in the treatment of cancers has been mentioned in several studies. Here, we investigated the efficacy of combined blockade of two inhibitory receptors, PD-1 and TIGIT, in restoring functional features of CD8+ T-cells in CLL. METHODS: CD8+ T-cells were separated from the peripheral blood of 11 CLL patients and targeted with malignant B-cells isolated from the same patients. Cells were then stimulated with anti-CD3/CD28 and PMA/ionomycin to assess their proliferative response and cytotoxic activity using MTT and CD107a degranulation assays, respectively. Cytokine production of isolated CD8+ T-cells was also determined using ELISA. RESULTS: There were no significant differences in proliferation and cytotoxic activity of CD8+ T-cells co-blocked with anti-PD-1/TIGIT compared to those single blocked with anti-PD-1, anti-TIGIT, or the control antibody. There was no significant difference in cytokine production of mentioned groups, either. CONCLUSIONS: Collectively, combined blockade of PD-1 and TIGIT failed to restore the proliferation and function of CD8+ T-cells isolated from CLL patients.

A 47-year-old man with rare serous cyst adenocarcinoma of the testis.

Although papillary serous cyst adenocarcinoma of the ovary is a common tumor, the incidence of ovarian-type papillary serous cyst adenocarcinoma in the testis is rare. Based on medical documents, there are only about 50 cases reported about testicular and paratesticular serous tumors.[1],[2],[3] Herein, we report a case of low-grade serous cyst adenocarcinoma of the testis that did unilateral orchiectomy and then came with retroperitoneal mass and lung metastasis. Chemotherapy was well tolerated, and now, after 1 year, he does not have any complaint.

Treatment by PI3K/mTOR Inhibitor BEZ235 Combined with TLR-7/8 Agonist Interfere with Immune Evasion Mechanisms of WEHI-3 Mouse Leukemia Cells.

BACKGROUND: Several PI3K/Akt/mTOR pathway inhibitors and TLR agonists induce tumor cell death. However, the mechanisms of these therapeutic approaches in acute myeloid leukemia (AML) cells are still unknown. OBJECTIVES: To investigate the effects of BEZ235, as a dual inhibitor of PI3K and mTOR pathways, and TLR7/8 agonist R848 on the expression and regulation of the immune inhibitory molecules in myeloid leukemia cells. METHODS: WEHI-3 leukemia cells were incubated with dual PI3K and mTOR inhibitor BEZ235 and TLR7/8 agonist R848 for 48 hrs. Firstly, cell viability was assessed by MTT method. The semi-quantitative relative mRNA expression of Galectin-9 (Gal-9), PD-L1, PVR, and STAT3 was assessed according to HPRT as a housekeeping gene. Finally, the protein expression of phosphorylated STAT3 was evaluated by western blotting analysis. RESULTS: WEHI-3 cells showed growth inhibition following treatment with BEZ235 and R848 whose combination exerted more proliferation arrest. The mRNA expression of Gal-9, PD-L1 and PVR immune checkpoint molecules significantly reduced in treated cells with BEZ235 and R848. Combined treatment indicated more reduction compared with the single treatment. Finally, the expression and phosphorylation of STAT3 were down-regulated after a single or dual treatment with BEZ235 and R848. CONCLUSION: Our results conclude that treatment with the combination of BEZ235 and R848 interferes with immune evasion mechanisms through STAT3-signaling pathway in WEHI-3 leukemia cells.

Effects of Vitamin E on Doxorubicin Cytotoxicity in Human Breast Cancer Cells in Vitro.

OBJECTIVE: This study aimed to evaluate in vitro synergistic anticancer effect of doxorubicin combined with Vitamin E. METHODS: The MTT assay was utilized to assess the cytotoxicity of Vitamin E and vitamin E combined with doxorubicin and vital activities of SKBR3, MDA-MB-231, and HFF cells over a 24-hour incubation period. In addition, the antioxidant properties of these interventions and the decrease of reactive oxygen species (ROS) content caused by the treatment were evaluated. RESULTS: The antiproliferative effect of doxorubicin increased significantly in combination with vitamin E (Doxcorobicin 2µM vs. Vitamin E 120µM, P=0.000). Despite reducing cell ROS content due to vitamin E treatment, the combination of vitamin E and doxorubicin showed no significant synergistic effect (Doxcorobicin 2µM vs. Vitamin E 120µM, P=0.998). CONCLUSION: This study indicated that the doxorubicin-vitamin E treatment reduced the viability of breast cancer cells with the minimum side effects on normal cells. In addition, the high dosage of vitamin E intensified the cytotoxicity of doxorubicin.

CD8+ T-cells Co-expressing PD-1 and TIGIT Are Highly Frequent in Chronic Lymphocytic Leukemia.

The role of immune checkpoint receptors in T-cell exhaustion has been demonstrated in several cancers. We investigated the co-expression of TIGIT/PD-1 and LAG-3/PD-1 cells in patients with chronic lymphocytic leukemia (CLL). The frequencies of TIGIT+PD-1+CD8+and LAG-3+PD-1+CD8+cells and relative mRNA expression of LSECtin and CD155 were examined in PBMCs from 33 CLL patients and 20 controls. The percentage of TIGIT+PD-1+CD8+cells was significantly higher in CLL patients than in control subjects, with the preference in advanced stage patients. However, LAG-3+PD-1+CD8+cell percentage was significantly lower in CLL patients than in the control subjects and no significant difference were found between the early and advanced stages of the disease. An increase in the mRNA expression level of LSECtin, but not that of CD155, was observed in CLL patients compared to the control subjects. Collectively, a higher co-expression of PD-1 and TIGIT on CD8+ T-cells in CLL compared to control subjects suggests an important role of TIGIT in T-cell exhaustion in CLL patients especially those with advanced disease.

Malus domestica reduces chemotherapy-induced nausea and vomiting: A randomized double-blind placebo-controlled clinical trial.

BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) is considered as the most common complications of chemotherapy which has a detrimental influence on the quality of life of patients with cancer. We assessed the efficacy of Apple (Malus domestica) syrup for reducing CINV. MATERIALS AND METHODS: This study was a randomized, double-blind, placebo-controlled trial carried out in a Hematooncology Clinic affiliated to Mazandaran University of Medical Sciences, Sari, Iran (from October 2017 to August 2018). Subjects were randomly allocated to receive apple syrup or placebo along with their previous antiemetic treatment and chemotherapy regimen, three times a day. Thirty-four patients received apple syrup (n = 16) or placebo (n = 18). Statistical analysis was conducted using SPSS software Version 21® (SPSS Inc., Chicago, IL, USA). A P < 0.05 indicated statistical significance. RESULTS: Both acute and delayed nausea grades were significantly lower in M. domestica syrup in comparison to placebo syrup (P = 0.001 and 0.001, respectively). The duration of nausea (P = 0.04) was lower in intervention group compared to placebo group. CONCLUSION: These findings demonstrated that M. domestica syrup can reduce the severity and duration of nausea in cancer patients who received chemotherapy.

Nationwide Prevalence of Diabetes and Prediabetes and Associated Risk Factors Among Iranian Adults: Analysis of Data from PERSIAN Cohort Study.

INTRODUCTION: Over the past decades prevalence of diabetes has increased in Iran and other countries. This study aimed to update the prevalence of diabetes and prediabetes in Iran and to determine associated sociodemographic risk factors, as well as diabetes awareness and control. METHODS: This is a nationally representative cross-sectional survey that included 163,770 Iranian adults aged 35-70 years, from different ethnic backgrounds, between 2014 and 2020. Diabetes was diagnosed at fasting blood sugar of ≥ 6.99 mmol/L (126 mg/dL), or receiving blood glucose-lowering treatment. Multivariable logistic regression was applied to detect determinants associated with prevalence of diabetes and prediabetes, as well as predictors of diabetes awareness and glycemic control. RESULTS: Sex- and age-standardized prevalence of diabetes and prediabetes was 15.0% (95% CI 12.6-17.3) and 25.4% (18.6-32.1), respectively. Among patients with diabetes, 79.6% (76.2-82.9) were aware of their diabetes. Glycemic control was achieved in 41.2% (37.5-44.8) of patients who received treatment. Older age, obesity, high waist to hip ratio (WHR), and specific ethnic background were associated with a significant risk of diabetes and prediabetes. Higher awareness of diabetes was observed in older patients, married individuals, those with high WHR, and individuals with high wealth score. Moreover, glycemic control was significantly better in women, obese individuals, those with high physical activity, educational attainment, and specific ethnic background. CONCLUSIONS: The prevalence of diabetes and prediabetes is increasing at an alarming rate in Iranian adults. High proportion of uncontrolled patients require particular initiatives to be integrated in the health care system.

The effect of a supportive program on coping strategies and stress in women diagnosed with breast cancer: A randomized controlled clinical trial.

AIM: To investigate the effect of a supportive program on coping strategies and stress in women with breast cancer. DESIGN: A randomized, two-armed, controlled trial. METHODS: Sixty women were randomly allocated to intervention group (N = 30) and control group (N = 30). The interventions were held in six sessions, weekly from August 2018-March 2019 It was consisting of education regarding breast cancer; progressive muscle relaxation; stress management; emotional coping; and problem-solving strategies. RESULTS: At baseline, there was no difference between the two groups regarding the mean score of coping strategies and stress. Supportive program group participants experienced a significantly higher increase on their problem-oriented coping strategies score in comparison with the control group. At the same time, scores in emotion-oriented coping strategies and stress decreased significantly in the intervention group compared with the control group. Result of this study can be used to develop relevant interventions targeting coping strategies to reduce stress among women with breast cancer.

Improvement in use of best practice in the care of patients with oral mucositis in a comprehensive cancer center in Iran: a best practice implementation case study.

INTRODUCTION: Oral mucositis is a common debilitating complication of cancer treatments, particularly chemotherapy and radiation. OBJECTIVES: The purpose of this study was to improve oral mucositis prevention and control among cancer patients through the implementation of best practice guidelines in a tertiary referral center in Northern Iran. METHODS: A clinical audit design was utilized in this implementation project. A preimplementation audit was conducted against nine best practice criteria for the prevention and treatment of oral mucositis among new cases of cancer patients in November and December 2019. Fifty cancer patients and 20 nurses participated in this phase of the clinical audit. The next step included a facilitated multidisciplinary focus group identifying targeted strategies and implementing them, completed in late December 2019. A postimplementation audit was then conducted on another 50 cancer patients and the same 20 nurses in January and early February 2020. The project utilized the Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research into Practice software. RESULTS: The preimplementation audit revealed gaps between the current practice and best practice across eight of the nine criteria. After implementing the targeted strategies, the outcomes improved across most of the criteria in the follow-up audit: 80% increase was observed in compliance of staff education, 100% increase in providing standard oral hygiene protocol in place, 64% increase in carrying out a dental examination and conducting initial oral cavity examination, and also 34% increase in conducting of ongoing oral cavity examination by a dentist, and finally 100% increase in providing preventive and therapeutic oral care regimens in place and oral pain assessment using a validated tool. CONCLUSION: The results of this project indicate that clinical auditing is an effective approach to the assessment of evidence-based care practices for oral mucositis among new cancer patients. Evidence-based oral mucositis management among cancer patients can be achieved by educating the patients and nursing staff using the newest guidelines and dentists' comprehensive dental and oral hygiene examinations.
