DeepTraSynergy: drug combinations using multimodal deep learning with transformers.

MOTIVATION: Screening bioactive compounds in cancer cell lines receive more attention. Multidisciplinary drugs or drug combinations have a more effective role in treatments and selectively inhibit the growth of cancer cells. RESULTS: Hence, we propose a new deep learning-based approach for drug combination synergy prediction called DeepTraSynergy. Our proposed approach utilizes multimodal input including drug-target interaction, protein-protein interaction, and cell-target interaction to predict drug combination synergy. To learn the feature representation of drugs, we have utilized transformers. It is worth noting that our approach is a multitask approach that predicts three outputs including the drug-target interaction, its toxic effect, and drug combination synergy. In our approach, drug combination synergy is the main task and the two other ones are the auxiliary tasks that help the approach to learn a better model. In the proposed approach three loss functions are defined: synergy loss, toxic loss, and drug-protein interaction loss. The last two loss functions are designed as auxiliary losses to help learn a better solution. DeepTraSynergy outperforms the classic and state-of-the-art models in predicting synergistic drug combinations on the two latest drug combination datasets. The DeepTraSynergy algorithm achieves accuracy values of 0.7715 and 0.8052 (an improvement over other approaches) on the DrugCombDB and Oncology-Screen datasets, respectively. Also, we evaluate the contribution of each component of DeepTraSynergy to show its effectiveness in the proposed method. The introduction of the relation between proteins (PPI networks) and drug-protein interaction significantly improves the prediction of synergistic drug combinations.

CFSSynergy: Combining Feature-Based and Similarity-Based Methods for Drug Synergy Prediction.

Drug synergy prediction plays a vital role in cancer treatment. Because experimental approaches are labor-intensive and expensive, computational-based approaches get more attention. There are two types of computational methods for drug synergy prediction: feature-based and similarity-based. In feature-based methods, the main focus is to extract more discriminative features from drug pairs and cell lines to pass to the task predictor. In similarity-based methods, the similarities among all drugs and cell lines are utilized as features and fed into the task predictor. In this work, a novel approach, called CFSSynergy, that combines these two viewpoints is proposed. First, a discriminative representation is extracted for paired drugs and cell lines as input. We have utilized transformer-based architecture for drugs. For cell lines, we have created a similarity matrix between proteins using the Node2Vec algorithm. Then, the new cell line representation is computed by multiplying the protein-protein similarity matrix and the initial cell line representation. Next, we compute the similarity between unique drugs and unique cells using the learned representation for paired drugs and cell lines. Then, we compute a new representation for paired drugs and cell lines based on the similarity-based features and the learned features. Finally, these features are fed to XGBoost as a task predictor. Two well-known data sets were used to evaluate the performance of our proposed method: DrugCombDB and OncologyScreen. The CFSSynergy approach consistently outperformed existing methods in comparative evaluations. This substantiates the efficacy of our approach in capturing complex synergistic interactions between drugs and cell lines, setting it apart from conventional similarity-based or feature-based methods.

Demanded interdisciplinary subjects for integration in medical education program from the point of view of graduated medical physicians and senior medical students: a nationwide mixed qualitative-quantitative study from Iran.

INTRODUCTION: This study aimed to detect interdisciplinary subjects for integration into the medical education program of Iran. METHODS: A qualitative-quantitative method was used. Firstly, interdisciplinary subjects demanded by medical graduates and senior medical students were defined by qualitative study. In the second stage, questionnaire was developed which based on the findings of qualitative stage, experts' opinion and reviewing of the national general guide of professional ethics for medical practitioners. Questionnaire consisted of demographic, occupational and thirteen interdisciplinary items. These items consisted of social determinants of health, social and economic consequences of disease, social prescribing, physicians' social responsibility, role of gender, racial, ethnic, social and economic issues in approach to patients, role of logic and mathematics in clinical decision-making, philosophy of medicine, maintaining work-life balance, self-anger management, national laws of medicine, religious law in medical practice, health system structure, and teamwork principles. Level and importance of knowledge and self-assessed educational needs were asked about each item. In the third stage, a national online survey was conducted. SPSS 25 was used for statistics. RESULTS: By content analysis of data in qualitative stage, 36 sub-themes and 7 themes were extracted. In the quantitative part, 3580 subjects from 41 medical universities across Iran participated in this study. 2896 (80.9%) were medical graduates and 684 (19.1%) were senior medical students. Overall, knowledge about interdisciplinary items was low to intermediate, while high to very high knowledge ranged from maximally 38.7% about socioeconomic consequences of disease to minimally 17.2% about social prescribing. Participants gave the most importance to the having knowledge about self-anger management (88.3%), maintaining work-life balance (87.2%) and social determinants of health (85.8%), respectively. However, national laws of medicine (77.6%), maintaining work-life balance (75.4%) and self-anger management (74%) were the first top three educational demands by participants. CONCLUSION: This study revealed a low to moderate level of knowledge about interdisciplinary topics among both graduated medical physicians and senior medical students. These groups showed a strong demand and tendency to know and to be educated about these topics. These findings underscore the urgency for educational reforms to meet the interdisciplinary needs of medical professionals in Iran.

Efferocytosis: a double-edged sword in microbial immunity.

Efferocytosis is characterized as the rapid and efficient process by which dying or dead cells are removed. This type of clearance is initiated via "find-me" signals, and then, carries on by "eat-me" and "don't-eat-me" ones. Efferocytosis has a critical role to play in tissue homeostasis and innate immunity. However, some evidence suggests it as a double-edged sword in microbial immunity. In other words, some pathogens have degraded efferocytosis by employing efferocytic mechanisms to bypass innate immune detection and promote infection, despite the function of this process for the control and clearance of pathogens. In this review, the efferocytosis mechanisms from the recognition of dying cells to phagocytic engulfment are initially presented, and then, its diverse roles in inflammation and immunity are highlighted. In this case, much focus is also laid on some bacterial, viral, and parasitic infections caused by Mycobacterium tuberculosis (M. tb), Mycobacterium marinum (M. marinum), Listeria monocytogenes (L. monocytogenes), Chlamydia pneumoniae (CP), Klebsiella pneumoniae (KP), Influenza A virus (IAV), human immunodeficiency virus (HIV), and Leishmania, respectively.

Cell membrane biomimetic nanoparticles in drug delivery.

Despite the efficiency of nanoparticle (NP) therapy, in vivo investigations have shown that it does not perform as well as in vitro. In this case, NP confronts many defensive hurdles once they enter the body. The delivery of NP to sick tissue is inhibited by these immune-mediated clearance mechanisms. Hence, using a cell membrane to hide NP for active distribution offers up a new path for focused treatment. These NPs are better able to reach the disease's target location, leading to enhanced therapeutic efficacy. In this emerging class of drug delivery vehicles, the inherent relation between the NPs and the biological components obtained from the human body was utilized, which mimic the properties and activities of native cells. This new technology has shown the viability of using biomimicry to evade immune system-provided biological barriers, with an emphasis on restricting clearance from the body before reaching its intended target. Furthermore, by providing signaling cues and transplanted biological components that favorably change the intrinsic immune response at the disease site, the NPs would be capable interacting with immune cells regarding the biomimetic method. Thus, we aimed to provide a current landscape and future trends of biomimetic NPs in drug delivery.

Spiritual Care in Hospitalized Patients in Iran: An Action Research Study.

Religious practices can raise the sense of merit and hope through overcoming the feeling of isolation. Studies conducted in this area have indicated that patients may desire to have their spiritual needs met. Nonetheless, sufficient attention has not been paid to these special needs. Therefore, this study aimed to identify the barriers to the provision of spiritual care for hospitalized patients. This is an action research study in which a total of 11 nurses and 76 hospitalized patients were recruited using purposive and convenience sampling, respectively. Data were collected using a combination of qualitative and quantitative methods. In the action cycles, the participants' concerns were examined, constructed, then evaluated, and re-constructed using reflective assessment. The qualitative and quantitative data were analyzed using the content analysis approach and the Mann-Whitney U, Chi-squared, and t-tests, respectively. At the first stage, the results of the content analysis showed the lack of professional knowledge and the existence of organizational barriers in the provision of spiritual care for patients. Reflection in the final stage led to the discovery of four concepts including (a) perceived advantages of change in performance, (b) being capable of providing spiritual care, (c) getting positive feedback, and (d) preparation for improving the provision of spiritual care. The results of the quantitative analysis indicated a significant increase in the mean score of patient satisfaction after the provision of spiritual care (p = .001). The results of this study led the authors to a deeper understanding of various dimensions of spiritual care among patients hospitalized in the cardiology ward and ultimately improved the patients and their families' level of satisfaction.

Can tele-nursing affect the supportive care needs of patients with cancer undergoing chemotherapy? A randomized controlled trial follow-up study.

PURPOSE: In some countries, telephone-based support is one of the key services used for supporting patients with cancer. However, there is a lack of research on the efficacy of this method in Iran. This study aimed to evaluate the effects of tele-nursing on supportive care needs (SCNs) of patients with cancer undergoing chemotherapy. METHODS: This randomized controlled trial was conducted on 60 patients with cancer undergoing chemotherapy who were randomly assigned and allocated to two groups, an intervention group and a control group. Patients' SCNs were assessed in the baseline, and 1 and 2 months after commencement of the intervention using the SCNs Survey -Short Form 34. The data were analyzed through descriptive statistics, t-test, and repeated measure test, by SPSS version 16. RESULTS: There were no significant statistical differences in the mean score of dimensions and total SCNs between the two groups in baseline (p˃0.05). However, the results showed that the mean score of dimensions and total SCNs in the intervention group were significantly less than the control group, after the intervention (p˂0.05). CONCLUSIONS: Telephone-based support is an effective method to address and reduce SCNs of patients with cancer undergoing chemotherapy through increasing access to support for this population especially who may be in rural and remote settings. During the COVID_19 pandemic and given the vulnerability of patients with cancer, telephone support can be used to avoid unnecessary visits to hospitals and reduced the risk of transmitting the virus to the patients.

Reduction in maternal serum values of glucose and gamma-glutamyltransferase after supplementation with alpha-lipoic acid in women with gestational diabetes mellitus.

AIM: Alpha-lipoic acid (ALA) is a short chain fatty acid which has a key role in energy production. ALA is also known as a universal antioxidant. The aim of the present study was to explore the effects of ALA supplementation in women with gestational diabetes mellitus. METHODS: A randomized double-blind placebo-controlled clinical trial study was designed. Women with gestational diabetes mellitus (n = 60) during 24-28 weeks of gestation were selected and divided randomly into drug (n = 30) and placebo (n = 30) groups. Drug group supplemented with ALA (100 mg/day) for 8 weeks. The biochemical markers were measured before and after the intervention and considered significant at a P-value less than 0.05. RESULTS: Maternal circulating values of fasting blood sugar (P < 0.001), gamma-glutamyltransferase (P < 0.001) and alanine transaminase (P = 0.031) were decreased in the drug group after the intervention. However, values of urea, creatinine, uric acid, aspartate transaminase and alkaline phosphatase were not changed significantly after the trial. CONCLUSION: The present study has shown that supplementation with 100 mg/day of ALA had some beneficial effects on glucose metabolism and liver function in women with gestational diabetes mellitus.

Prediction of academic achievement based on learning strategies and outcome expectations among medical students.

BACKGROUND: One of the most important indicators of the effectiveness of teaching can be the academic achievement of learners, which can be influenced by different factors such as learning methods and individual motivations. The purpose of this study was to determine the ability of predicting academic achievement based on learning motivation strategies and outcome expectations based on a theoretical model. METHODS: This descriptive-analytic study was conducted with the participation of 380 male and female students of nine faculties of medical sciences of Shahid Beheshti University of Tehran. Multi-stage sampling along with the questionnaire of motivational strategies for learning and student outcome expectation scale were used for data collection. The college grade point average (CGPA) of students' past grades was considered as the academic performance variable. Data analysis was performed using Structural Equation Modeling (SEM) in AMOS software. RESULTS: The mean score of the structure of learning strategies, motivational strategies, outcome expectations, and students' GPA did not show significant statistical differences in terms of gender, marital status, residence location, field of study, and educational level. There was a direct and significant relationship between the motivational strategies' structures (R = 0.193, p < 0.001) as well as learning strategies (R = 0.243, p < 0.001) and the CGPA, while there was no relationship between outcome expectations and CGPA. Path analysis revealed that self-regulating learning strategies and motivational strategies can predict the academic achievement of these students. CONCLUSIONS: Considering the importance of active and independent learning among medical students, it is necessary for lecturers to use interactive and student-oriented patterns of teaching. Also, students should become familiar with self-regulating learning skills to better understand the information they receive.

Effects of coenzyme Q10 supplementation on serum values of adiponectin, leptin, 8-isoprostane and malondialdehyde in women with type 2 diabetes.

Patients with type 2 diabetes mellitus (T2DM) have been known to be suffering from coenzyme Q10 (CoQ10) deficiency which results in some complications in them. The purpose of this clinical trial study was to evaluate the effects of CoQ10 supplementation on serum values of adiponectin (A), leptin (L), 8-isoprostane, malondialdehyde (MDA), the A/L ratio in women with T2DM. Sixty-eight women with T2DM were enrolled in the current study and were randomly divided into drug (n = 34) and placebo (n = 34) groups who were consuming 100 mg CoQ10 and 100 mg cellulose acetate per day for 12 weeks, respectively. Measurements were performed at the beginning and after the intervention. Serum values of adiponectin (p = .001) and the A/L ratio (p = .001) were increased while values of leptin (p = .041), MDA (p = .023), 8-isoprostane (p = .004) were decreased significantly in drug group after intervention. This study had shown that CoQ10 supplementation in women with T2DM was effective in elevation of adiponectin and the A/L ratio and reduction of leptin, MDA and 8-isoprostane which could result in improving insulin resistance and modulating oxidative stress situation.

A comparison between effects of sudoku and mandala painting on anxiety of breast cancer patients undergoing chemotherapy.

Introduction: Once diagnosed with breast cancer, many women may experience psychological complications, such as anxiety. The grueling treatments that such patients may undergo, for example, chemotherapy, not only cause specific complications for them but also increase their anxiety level. A technique to manage these psychological consequences in patients with breast cancer is to play Sudoku or do Mandala painting. Purpose: This study aimed to compare the effects of Sudoku and Mandala painting on the anxiety level of patients with breast cancer undergoing chemotherapy. Methodology: This randomized clinical trial was conducted on 70 patients with breast cancer in Arak, Iran. The patients who met the inclusion criteria were selected through purposive sampling, and then they were assigned to one of the Mandala painting or Sudoku groups using block randomization. The data were collected using a demographics form and the Spielberger State-Trait Anxiety Inventory (STAI). All participants in both groups completed the research questionnaires before the intervention. The obtained data were analyzed using descriptive and inferential statistics in SPSS-26. Results: The results indicated that there was a significant difference between the pre-test and post-test anxiety scores in both Sudoku and Mandala painting groups (P = 0.0001). The difference between the pre-test and post-test mean anxiety scores was 6.09 ± 4.02 in the Sudoku group and 48.93 ± 13.8 in the Mandala painting group. The results of the inter-group comparison also showed a significant difference between the two groups in post-test mean anxiety score (P = 0.0001), proving that Mandala painting was more effective in reducing the anxiety of patients. Conclusion: Mandala painting was more effective than Sudoku in reducing the anxiety level of patients with breast cancer. It can be hence concluded that Mandala painting can be used as a relaxing art therapy technique in these patients.

Interface between Resolvins and Efferocytosis in Health and Disease.

Acute inflammation resolution acts as a vital process for active host response, tissue support, and homeostasis maintenance, during which resolvin D (RvD) and E (RvE) as mediators derived from omega-3 polyunsaturated fatty acids display specific and stereoselective anti-inflammations like restricting neutrophil infiltration and pro-resolving activities. On the other side of the coin, potent macrophage-mediated apoptotic cell clearance, namely efferocytosis, is essential for successful inflammation resolution. Further studies mentioned a linkage between efferocytosis and resolvins. For instance, resolvin D1 (RvD1), which is endogenously formed from docosahexaenoic acid within the inflammation resolution, thereby provoking efferocytosis. There is still limited information regarding the mechanism of action of RvD1-related efferocytosis enhancement at the molecular level. The current review article was conducted to explore recent data on how the efferocytosis process and resolvins relate to each other during the inflammation resolution in illness and health. Understanding different aspects of this connection sheds light on new curative approaches for medical conditions caused by defective efferocytosis and disrupted inflammation resolution.

Complementary and alternative medicine application in cancer patients in Iran.

PURPOSE: Nowadays, complementary and alternative medicine (CAM) is used by cancer patients all over the world. The aim of this study was to investigate the prevalence of CAM use in patients with cancer in Iran. METHODS: This descriptive-analytical study was conducted on 320 cancer patients in Arak. For gathering information, a researcher-made questionnaire was used. This questionnaire was consisted of two parts: demographic and clinical information; and patient's attitude toward using complementary and alternative medicine treatments and their effectiveness, as well as how much they used different kinds of these treatments. The data were analyzed using SPSS software version 16. RESULTS: Our findings showed that average age of participants was 55.11 ± 15.58. Most of them had leukemia (25.9%) and underwent chemotherapy (55%), and 141 (44.3%) of individuals were using CAM. Majority of patients (73.2%) were using CAM to improve physical conditions, 61.4% were using it simultaneously with conventional medical treatments, and 25% to reduce pain. Participants have reported visiting holy places, yoga, prayer therapy, and using medicinal plants and special diets, respectively. CONCLUSION: Considering the high number of patients using CAM treatments, proper planning and implementation to educate professional members of health team, especially doctors and nurses about CAM treatments is essential. The most important CAM treatments to be educated are spiritual therapies, yoga, medicinal plants, and diet therapy. Moreover, support and education about using these kinds of treatment should be considered in the supportive care program for patients with cancer.

CRISPR: A Promising Tool for Cancer Therapy.

The clustered regularly interspaced short palindromic repeats system, called CRISPR, as one of the major technological advances, allows geneticists and researchers to perform genome editing. This remarkable technology is quickly eclipsing zinc-finger nucleases (ZFNs) and other editing tools, and its ease of use and accuracy have thus far revolutionized genome editing, from fundamental science projects to medical research and treatment options. This system consists of two key components: a CRISPR-associated (Cas) nuclease, which binds and cuts deoxyribonucleic acid (DNA) and a guide ribonucleic acid (gRNA) sequence, directing the Cas nuclease to its target site. In the research arena, CRISPR has been up to now exploited in various ways alongside gene editing, such as epigenome modifications, genome-wide screening, targeted cancer therapies, and so on. This article reviews the current perceptions of the CRISPR/Cas systems with special attention to studies reflecting on the relationship between the CRISPR/Cas systems and their role in cancer therapy.

The Effects of Passive Blinking on Exposure Keratopathy among Patients in Intensive Care Units.

Background: Patients in Intensive Care Units (ICUs) are at risk of eye disorders such as Exposure keratopathy (EK) due to impaired blinking and incomplete eye closure. The aim of this study was to assess the effects of passive blinking exercise (PBE) on EK among patients in ICUs. Materials and Methods: This single-blind, randomized, clinical trial was conducted in 2017. The study participants included 51 patients purposively recruited from the three ICUs of Valiasr Teaching Hospital, Arak, Iran. Through coin tossing, one eye of each participant was randomly allocated to the intervention group and the other to the control group. The eye in the control group received routine eye care, whereas the eye in the intervention group received routine eye care and PBE for a week. EK prevalence and severity were assessed daily for 7 consecutive days using fluorescein eye staining papers and an ophthalmoscope with a cobalt blue filter. Results: The study groups did not significantly differ from each other in terms of the baseline prevalence and severity of EK. After the intervention, the prevalence of EK (χ 2 = 13.44, df = 1, p < 0.001) and the prevalence of grade II EK (χ 2 = 8.33, df = 1, p = 0.003) in the intervention group were significantly lower than the control group. Conclusions: PBE is effective in significantly reducing EK prevalence and severity among patients in ICUs. Therefore, critical care nurses are recommended to use PBE for EK prevention and management.

Exposure keratopathy and its associated risk factors in patients undergoing general anesthesia in nonocular surgeries.

INTRODUCTION: The most common eye injury during and after general anesthesia is corneal abrasion which can occur at any time after anesthesia and even up to 24 h after it. The aim of this study was to investigate the incidence and factors associated with corneal injury in patients undergoing nonocular surgery. METHODS: This was a descriptive cross-sectional study. A total of 170 patients, who were admitted to the operating room and met the inclusion criteria, were selected through simple nonprobability sampling. Data collection forms were used in order to assess the incidence of corneal injury and its related risk factors. The National Eye Institute scale with fluorescein paper and cobalt blue light by slit lamp were utilized to examine exposure keratopathy. RESULTS: Overall, the results showed that the incidence of keratopathy immediately after eye care removal was found to be 64.7% in the operating room, 65.9% in the recovery room, and 41.2% in 24 h after the surgery. Smokers' patients and drug abusers under general anesthesia underwent endotracheal intubation, received more opioids preoperatively, and had more perioperative bleeding and fluid intake. Moreover, in patients who had received more oxygen flow in the recovery room; the rate of keratopathy was higher. CONCLUSION: Smoking, drug usage, and receiving endotracheal intubation are the risk factors of keratopathy. Therefore, for high-risk patients and procedures, it is indispensable to both obtain preoperative information and take intraoperative precautions in order to prevent eye injuries. Future studies are needed to demonstrate these finding.

Randomized controlled trial of the foot reflexology on pain and anxiety severity during dressing change in burn patients.

BACKGROUND: One of the most important problems in burn patients was pain, especially in dressing changes. This pain can lead to anxiety in the patient. The aim of this study was to determine the effect of foot reflexology on pain and anxiety severity in burn patients. METHODS: This study was a randomized controlled trial, in which 66 patients with burn injuries referred to Vali-e-asr Hospital, Arak, Iran participated. After obtaining written consent, patients were enrolled to study according to inclusion criteria and then, divided into intervention (n = 33) and control (n = 33) groups using simple random allocation. In the intervention group, in addition to standard care, reflexology was performed for one week on Saturday, Monday and Wednesday (three times in a week). The intervention was done one hour before dressing change in a separate room for 30 min. The control group received only standard care during this time (both intervention and control groups were the same in the type of treatment, and reflexology was considered as an extra care in the intervention group). Severity of pain and anxiety in both groups was measured using visual analog scale twice a day (5-10 min before dressing change and 5-10 min after dressing change) for six days. SPSS software ver. 15 was used for statistical analysis. Mean and standard deviation were used for quantitative variables and qualitative variables were reported as frequency and percentage. Data were analyzed using Chi­square, Mann-Whitney, Fisher's exact tests, and paired t-test. The Kolmogorov-Smirnov test was used to check the normality of data. RESULTS: The results showed no significant difference in severity of pain (p = 0.25) and anxiety (p = 0.37) between the two groups on the first day, before the intervention. In the following days, the results showed no significant difference between the two groups in the second and third treatments after intervention . However, the mean pain scores showed a significant difference between the two groups in the forth (p = 0.005), fifth (p = 0.001), and sixth (p = 0.001) days after intervention. Anxiety scores also showed a significant difference between the two groups on the fourth (p = 0.01), fifth (p = 0.001), and sixth (p = 0.001) days. CONCLUSIONS: Our results showed foot reflexology is an appropriate and safe intervention for management of pain and anxiety of burn patients. Therefore, it can be used as a complementary method alongside other methods.

The effect of mandala colouring on anxiety in hospitalized COVID-19 patients: A randomized controlled clinical trial.

COVID-19 significantly affects patients' mental health, triggering a wide range of psychological disorders, including anxiety. The aim of this study was to investigate the effect of mandala colouring on the anxiety of hospitalized COVID-19 patients. In this randomized controlled clinical trial, 70 hospitalized patients with COVID-19 were randomly divided between the intervention and control groups. Standard care was provided for both groups. The intervention group spent 30 min/day for six consecutive days performing mandala colouring. Patient anxiety was measured prior and subsequent to the intervention in both groups using the Spielberger State-Trait Anxiety Inventory. Data were analysed using SPSS software version 25. The mean anxiety score was not significantly different between the two groups before the intervention (P = 0.08). Subsequent to the intervention, the mean anxiety score in the intervention and control groups was 44.05 ± 4.67 and 67.85 ± 6.25, respectively, indicating a statistically significant (P = 0.0001) decrease in the anxiety measured among the intervention group as compared with that of the control group. The results of this study show that 30 min of mandala colouring daily is an effective strategy for reducing anxiety in hospitalized COVID-19 patients. Mandala colouring can complement routine treatment and provides a non-pharmaceutical option for decreasing patient anxiety.

Improving the endothelial dysfunction in type 2 diabetes with chromium and vitamin D3 byreducing homocysteine and oxidative stress: A randomized placebo-controlled trial.

BACKGROUND: Chromium picolinate (CrPic) and vitamin D3 are known as two antioxidant micronutrients. Through inducing endothelial dysfunction, oxidants such as homocysteine (Hct) and malondialdehyde (MDA) lead to cardiovascular disease in type 2 diabetes mellitus (T2DM). No published data has directly examined the effects of these two antioxidants on improving the endothelial dysfunction in T2DM throughreducing homocysteine and oxidative stress. METHODS: Subjects (n = 92) in this randomized, double blind, placebo-control study were randomly assigned to receive oral placebo (group I), D3 (group II: 50,000 IU/ week), chromium picolinate (CrPic) (group III: 500 µg/day), and both vitamin D3 and CrPic (group IV) for four months. Fasting blood samples were drawn at study baseline and following intervention to determine Hct, MDA, total antioxidant capacity (TAC), total thiol groups (SHs), vascular cell adhesion molecule- 1 (VCAM-1), and plasminogen activator inhibitor-1 (PAI-1). RESULTS: After intervention, MDA significantly decreased in groups II and IV; TAC significantly increased in group IV, and SHs significantly augmented in group III; Hct was significantly reduced in groups II, III, and IV; and VCAM-1 significantly decreased in groups III and IV and PAI-1 was significantly reduced in groups II, III, and IV. CONCLUSION: Our findings suggest that through reducing homocysteine and oxidative stress and improving endothelial dysfunction, chromium and vitamin D3 co-supplementation might be predictive and preventive of cardiovascular diseasesassociated with T2DM.

The effect of Benson's relaxation response on sleep quality and anorexia in cancer patients undergoing chemotherapy: A randomized controlled trial.

BACKGROUND AND OBJECTIVES: Patients with cancer experience many side effects due to its nature and usual treatments. Sleep disorders and anorexia are the most commonly reported symptoms in cancer patients undergoing chemotherapy. The present study aimed to investigate the effect of Benson's Relaxation Response (BRR) on sleep quality and anorexia in cancer patients undergoing chemotherapy. METHODOLOGY AND PARTICIPANTS: In the present clinical trial, a total of 84 patients were enrolled and randomly divided into two groups of experimental and control. Benson's relaxation response was administered to the experimental group twice a day over 5 consecutive days. Data was collected using St. Mary's Hospital Sleep Questionnaire (SMHSQ) and anorexia questionnaire with Visual Analog Scale (VAS). RESULTS: The results of our study showed a significant improvement in the sleep quality in the experimental group at 24 (p = 0.02) and 48 (p = 0.001) hours after the intervention compared to the control group. Benson's relaxation response (BRR) also had a significant effect on the anorexia in the experimental group at 24 (7.5 ± 1.6) and 48 (6.9 ± 2.1) hours after the intervention compared to the control group. No side effects were reported during the study and follow-up period. CONCLUSION: Benson's relaxation response as a complementary method may improve sleep quality and anorexia in cancer patients undergoing chemotherapy. Further studies with greater sample size and longer follow-up period are needed to confirm the current findings.
