Discovering the Potential Value of Coenzyme Q10 as an Adjuvant Treatment in Patients With Depression.

PURPOSE/BACKGROUND: Depressive disorder or mental cold is the most common mental disorder, and depression exists all over the world and in all countries and cultures. The results of several studies have shown that using compounds with antioxidant properties has been fruitful in patients with depression. Coenzyme Q10 (CoQ10) is a fat-soluble antioxidant and exerts its antioxidant effect by directly neutralizing free radicals or reducing tocopherol and preventing the inhibition of mitochondrial activity because of oxidative stress. This study aimed to investigate the effects of oral CoQ10 in patients with depression as an adjunctive treatment. METHODS/PROCEDURES: Sixty-nine patients with moderate and severe depression were randomly divided into 2 CoQ10 groups (36) and placebo (33). The first group of patients received CoQ10 supplements at a dose of 200 mg daily for 8 weeks along with standard interventions and treatments for depression, and the second group received standard treatments for depression along with a placebo. The change in the score of Montgomery-Åsberg Depression Rating Scale depression scale was evaluated 4 and 8 weeks after the intervention. Also, at baseline and 8 weeks later at the end of the study, serum levels of total antioxidant capacity, total thiol groups, nitric oxide, malondialdehyde, and interleukin 6 were assessed. FINDINGS/RESULTS: The changes in the depression score at the end of the study showed that, in the group receiving the CoQ10 supplement after 8 weeks, there was a reduction in depression symptoms, which was statistically significant compared with before the start of the study Meanwhile, no significant changes were observed in the patients of the placebo group in terms of symptom reduction. Compared with baseline and the placebo condition, serum levels of nitric oxide and total thiol groups significantly decreased and increased, respectively. Also, no statistically significant changes were observed for interleukin 6, malondialdehyde, and total antioxidant capacity. IMPLICATIONS/CONCLUSIONS: A dose of 200 mg of CoQ10 supplement daily for 8 weeks can reduce depression and fatigue, as well as improve the quality of life of patients with depression. In addition, CoQ10 can significantly improve inflammation and oxidative stress status in patients with depression.

Effects of atypical antipsychotics on serum asprosin level and other metabolic parameters in patients with schizophrenia.

BACKGROUND: In this cross-sectional study, we compared fasting serum asprosin levels and metabolic parameters between patients receiving one of three atypical antipsychotics (olanzapine, risperidone, or aripiprazole) and healthy subjects. METHODS: The study population included 62 adult outpatients with schizophrenia and 22 healthy controls, matched for age and gender. Patients were in remission and had been on stable monotherapy with one of these atypical antipsychotics for over 6 months. Body Mass Index (BMI) and fasting serum levels of asprosin, glucose, HA1c, insulin, and lipid profile were compared across the investigated groups. Additionally, the number of participants meeting the insulin resistance criterion, defined as homeostasis model assessment for insulin resistance (HOMA-IR) >2.5, as well as the number of participants with elevated BMI levels (men >27 kg/m2, women >25 kg/m2) were compared among the groups. RESULTS: We observed statistically significant differences in BMI and fasting serum levels of glucose, HA1c, insulin, triglyceride (TG), high-density lipoprotein cholesterol, and asprosin among patients receiving olanzapine or risperidone, as compared to those receiving aripiprazole and healthy subjects. Patients on aripiprazole exhibited values comparable to healthy subjects, whereas those on risperidone or olanzapine showed significantly higher values, with the highest observed in the olanzapine group. Additionally, the prevalence of participants meeting the insulin resistance criterion and those with elevated BMI was also greater in individuals receiving olanzapine or risperidone compared to those on aripiprazole and healthy subjects. Serum asprosin levels showed a significant positive correlation with BMI and several metabolic parameters, including HbA1c, fasting insulin, HOMA-IR, and TG. No significant differences were observed among the investigated groups in terms of serum levels of total cholesterol and low-density lipoprotein cholesterol. CONCLUSIONS: Our cross-sectional study highlights the association between elevated asprosin levels, weight gain, and metabolic disorders in patients treated with olanzapine and risperidone. Given the bidirectional nature of the relationship between serum asprosin levels and these metabolic disturbances, further research is warranted to elucidate potential causative pathways.

Comparative study of AR infographic posters vs. offline videos for micro-video delivery in cardiology education.

Augmented reality has promised a new paradigm in medical education. Multimedia videos are the most preferred assent for augmentation. So, this study aimed to assess the effect of using an augmented reality infographic poster for delivering micro-videos on the knowledge and satisfaction of medical students in cardiology rotation. Sixty students participated in this quasi-experimental study and were allocated to three study groups; namely routine method, routine method plus offline micro-video delivery, and routine method plus micro-video delivery in an augmented reality infographic poster. The students' knowledge and satisfaction were evaluated through a multiple-choice question pre and post-test and a satisfaction questionnaire respectively. Within-group comparison of pre and post-test scores showed a significant increase in each study group (all p-values = 0.000). The highest post-test score was for the offline micro-video delivery group and pairwise comparisons of post-test scores showed a significant difference between this group and the control one (p-value = 0.013). Additionally, the augmented reality infographic poster group had the highest satisfaction score (p-value = 0.000). This experience showed the positive effect of micro-videos in clinical education. Although students were satisfied with accessing these videos through an augmented reality infographic poster, their knowledge acquisition was better when they received them offline.

Prevention of contrast induced-acute kidney injury using coenzyme Q10 in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

PURPOSE: We assessed the potential effect of CoQ10 administration for the prevention of contrast induced-acute kidney injury (CI-AKI) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). METHODS: One hundred fifty STEMI patients who were candidates for primary PCI, along with intravenous saline hydration, randomly received a placebo or CoQ10. CoQ10 was administrated orally, 400 mg before the procedure and 200 mg twice daily after the procedure for three consecutive days. Serum creatinine concentration and corresponding creatinine clearance (estimated by the CKD Epidemiology Collaboration (CKD-EPI) creatinine equation) were measured at baseline and 24, 48, and 72 h after primary PCI. Furthermore, the serum level of superoxide dismutase (SOD), total antioxidant capacity (TAC), and malondialdehyde (MDA) was measured before and 72 h after primary PCI. RESULTS: The mean serum creatinine concentration before contrast administration was similar in the two groups (0.98 ± 0.08 versus 0.99 ± 0.09 mg/dL). While in both study groups, compared to baseline, the mean serum creatinine concentration increased at 48 and 72 h after contrast exposure, the CoQ10 group showed a lower serum creatinine concentration than the placebo group (P-value = 0.017 and 0.004, respectively). However, comparing the mean values of creatinine clearance between the groups at the study time points did not demonstrate a statistically significant difference. CI-AKI, defined as a > 25% or 0.5 mg/dL increase in baseline serum creatinine concentration, occurred in 8.00% of the cases in the CoQ10 group versus 20.00% in the placebo group (P-value = 0.034). Furthermore, at 72 h, the CoQ10-treated group exhibited higher serum levels of SOD and TAC and a lower MDA level than the placebo-treated group. CONCLUSIONS: Our research's findings proposed CoQ10 supplementation as an adjuvant to saline hydration as a preventive approach against CI-AKI. TRIAL REGISTRATION: The trial was registered at Iranian Registry of Clinical Trials ( https://www.irct.ir/trial/60435 , identifier code: IRCT20120215009014N414). Registration date: 2021-12-29.

Comparison of the efficacy of equivalent doses of dexamethasone, methylprednisolone, and hydrocortisone for treatment of COVID-19-related acute respiratory distress syndrome: a prospective three-arm randomized clinical trial.

BACKGROUND: This prospective controlled clinical trial aimed to compare the efficacy of methylprednisolone, dexamethasone, and hydrocortisone at equivalent doses in patients with severe COVID-19. METHODS: In total, 106 patients with mild to moderate COVID-19-related acute respiratory distress syndrome (ARDS) were randomized to receive either dexamethasone (6 mg once a day), methylprednisolone (16 mg twice a day), or hydrocortisone (50 mg thrice a day) for up to 10 days. All participants received a standard of care for COVID-19. The primary and secondary efficacy outcomes included all-cause 28-day mortality, clinical status on day 28 assessed using the World Health Organization (WHO) eight-category ordinal clinical scale, number of patients requiring mechanical ventilation and intensive care unit (ICU) care, number of ventilator-free days, length of hospital and ICU stay, change in PaO2:FiO2 ratios during the first 5 days after treatment, and incidence of serious adverse events. P-values below 0.008 based on Bonferroni's multiple-testing correction method were considered statistically significant. RESULTS: According to the obtained results, there was a trend toward more favorable clinical outcomes in terms of needing mechanical ventilation and ICU care, number of ventilator-free days, change in PaO2:FiO2 ratios during the first 5 days after treatment, clinical status score at day 28, length of ICU and hospital stay, and overall 28-day mortality in patients receiving dexamethasone compared to those receiving methylprednisolone or hydrocortisone; however, likely due to the study's small sample size, the difference between groups reached a significant level only in the case of clinical status score on day 28 (p-value = 0.003). There was no significant difference in the incidence of serious adverse events between the study groups. CONCLUSION: Based on the results, severe cases of COVID-19 treated with dexamethasone might have a better clinical status at 28-day follow-up compared to methylprednisolone and hydrocortisone at an equivalent dose. Larger multicenter trials are required to confirm our findings.

Coenzyme Q10 as a potential add-on treatment for patients suffering from painful diabetic neuropathy: results of a placebo-controlled randomized trial.

BACKGROUND: We hypothesized that the addition of coenzyme Q10 (CoQ10) to pregabalin might be helpful in improving symptoms in patients suffering from painful diabetic neuropathy (PDN). METHODS: One hundred twelve patients with PDN were randomly allocated to receive CoQ10 + pregabalin (57 patients) or placebo + pregabalin (55 patients). Besides pregabalin (150 mg/day), the patients, upon their group assignment, received CoQ10 at a dosage of 100 mg every 8 h or matched placebo for 8 consecutive weeks. The primary efficacy measure was the changes in the pain intensity from baseline to endpoint measured on an 11-point NRS (numeric rating scale). Secondary efficacy measures included the changes in the pain-associated sleep interference score (SIS) as well as the patients' global improvement with treatment measured on the Clinicians' and Patients' Global Impression of Change (CGIC/PGIC). RESULTS: On the intent­to­treat population (ITT) analysis, the CoQ10 + pregabalin regimen resulted in significantly greater pain relief than the placebo + pregabalin regimen. By the end of week 2, the decrease in the mean pain NRS score was similar in both groups, but at the end of weeks four and eight, the decrease in the mean pain NRS score was significantly greater in patients taking CoQ10 + pregabalin than in those taking placebo + pregabalin (p value = 0.01 and < 0.001, respectively). Likewise, at the end of week 8, the decrease in the pain-associated SIS was significantly greater in the patients supplemented with CoQ10 compared to placebo. Furthermore, the proportion of the responder patients (those having ≥ 50% decline in the mean pain NRS score) as well as the proportion of patients rated ''very much'' or ''much improved'' on the CGIC/PGIC scales were also significantly higher in the CoQ10 + pregabalin-treated patients than placebo + pregabalin-treated patients. CONCLUSIONS: Our data support the idea that diabetic patients suffering from PDN may benefit from using antioxidant and anti-inflammatory supplements like CoQ10. However, further studies are required before supplementation with CoQ10 can be recommended for treating PDN. TRIAL REGISTRATION: The trial was registered at Iranian Registry of Clinical Trials (identifier code: IRCT20120215009014N385). Registration date: 2021-02-21.

Evaluation of serum levels of asprosin and other metabolic profiles in patients with idiopathic tonic-clonic generalized epilepsy on treatment with valproic acid.

BACKGROUND: This cross-sectional research was undertaken to determine the serum levels of asprosin, a novel white adipose tissue-derived glucogenic adipokine, in epileptic patients on valproic acid treatment. METHODS: Sixty-six patients diagnosed with idiopathic tonic-clonic generalized epilepsy were divided into three groups: those treated with valproic acid (n = 22), those treated with lamotrigine (n = 22), and twenty-two newly diagnosed or untreated patients. A control group was twenty-two, healthy volunteers with a similar distribution of gender and age. Body mass index (BMI) and fasting serum levels of asprosin, glucose, glycohemoglobin (HbA1c), insulin, and lipid profile were measured for both patients and control groups. Additionally, homeostasis model assessment for insulin resistance (HOMA-IR) was also calculated for the investigated groups. RESULTS: The mean BMI values and fasting serum levels of glucose, HbA1c, insulin, total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglyceride were much higher in subjects treated with valproic acid than those in the other study groups. Furthermore, a higher number of participants in the valproic acid group fulfilled the insulin resistance criterion (defined as HOMA-IR > 2.5) compared with those in other study groups. The mean fasting serum asprosin concentration was also significantly higher in the valproic acid group than in other study groups. This was while the values of the study parameters were comparable in the healthy, un-treated, and lamotrigine groups. CONCLUSIONS: Our finding suggested that elevated asprosin level might be one of the pathological mechanisms involved in the development of obesity, insulin resistance, and metabolic disturbances related to valproic acid treatment.

Influence of Simvastatin as Augmentative Therapy in the Treatment of Generalized Anxiety Disorder: A Pilot Randomized, Placebo-Controlled Study.

BACKGROUND: Preliminary evidence is promising regarding the anxiolytic effects of statins in animal models of anxiety. Hence, this study aimed to evaluate the efficacy of simvastatin augmentation versus placebo in the treatment of patients with generalized anxiety disorder (GAD) with residual symptoms despite treatment with selective serotonin reuptake inhibitors (SSRIs). METHODS: A double-blind, 8-week controlled trial was conducted from August 2018 to December 2019 in an outpatient psychiatry clinic in Hamadan, Iran. A total of 138 patients with a diagnosis of GAD were assessed for eligibility. Of them, 84 patients who met the study criteria were randomly assigned either to the adjuvant simvastatin (20 mg/day) or to the placebo group. Standard medication consisting of SSRIs was consistent 2 months prior to and during the study. The severity of anxiety symptoms for each patient was assessed based on the Hamilton Anxiety Rating Scale (HAM-A) score at baseline, week 4, and week 8 after treatment. Additionally, blood lipid values were assessed at baseline and on completion of the study. RESULTS: Thirty-three out of 42 patients in the intervention group and 35 out of 42 patients in the control group completed the 8 weeks of the study period. Compared to the placebo group, in the simvastatin group cholesterol, triglycerides, and low-density lipoprotein significantly decreased, and high-density lipoprotein significantly increased over time. General linear model analysis demonstrated that although over time a higher decrease in mean HAM-A scores was observed in the intervention group compared to the control group, this difference was not statistically significant (p = 0.11). In addition, at the end of the study, the number of responders and remitters was comparable in the two groups. CONCLUSIONS: The results from this clinical study did not support the potential efficacy of adjunctive simvastatin in the treatment of patients with GAD. Thus, large-scale and long-term clinical trials are required to more accurately assess the potential efficacy of statins in the treatment of patients with anxiety disorders.

ADA gene haplotype is associated with coronary-in-stent-restenosis.

BACKGROUND: Cardiovascular diseases (CVDs) are the most common and the first cause of death worldwide. While some studies have investigated the association of the Adenosine Deaminase (ADA) gene with CDVs, its roles on in-stent restenosis (ISR) has not been studied. METHODS AND RESULTS: In this study, we investigated the role of ADA gene variants in both genetic and haplotype models on the risk of ISR. 91 samples were included in this study. The subjects were divided into two groups regarding having or not-having ISR (n = 40 ISR+ and n = 51 ISR-). The genotyping for G22A (rs73598374) and A4223C (rs452159) polymorphisms was performed using PCR-RFLP method. Statistical analysis was performed by SPSS v. 20 and Haploview 4.2 softwares. The basic demographic conditions in ISR groups were statistically similar. There was a significant association between A allele of rs452159 ISR groups after adjustment (allelic model: P value = 0.028, OR(95%CI) = 0.366(0.149-0.899)), while rs73598374 polymorphism shows no significant association with ISR. In haplotype analysis, the GA (G:rs73598374/A:rs452159) haplotype decreased the risk of ISR (P value = 00.025, OR(95%CI) = 0.382(0.161-0.907)). CONCLUSIONS: This study suggests that A allele of ADA rs452159 polymorphism and GA (G:rs73598374/A:rs452159) haplotype may be related to decreased risk of ISR in CAD patients receiving drug-eluting stent and offers more observational studies on ADA variants in other populations to generate a potential haplotype panel for ISR risk assessment.

Adjuvant use of melatonin for relieving symptoms of painful diabetic neuropathy: results of a randomized, double-blinded, controlled trial.

PURPOSE: The trial aimed to investigate the effectiveness of exogenous melatonin as an adjuvant to pregabalin for relief of pain in patients suffering from painful diabetic neuropathy (PDN). PATIENTS AND METHODS: This randomized, double-blind, placebo-controlled trial was carried out between October 2019 and December 2020 in an outpatient specialty clinic in Iran. One-hundred-three type 2 diabetic patients suffering from PDN were randomized into either the melatonin group (n = 52) or the placebo group (n = 51). Besides pregabalin at a dose of 150 mg per day, patients started with melatonin or an identical placebo, at a dose of 3 mg/day at bedtime for 1 week, which was augmented to 6 mg/day for further 7 weeks. The primary outcomes were changes in mean NRS (numerical rating scale) pain score from baseline to endpoint and responder rate (patients with a reduction of 50% and higher in average pain score compared with baseline). Secondary endpoints were changes in mean NRS pain-related sleep-interference score, overall improvement evaluated by Patient and Clinical Global Impressions of Change (PGIC, CGIC), and impact of the intervention on patient's Health-related quality of life (QOL). All analyses were conducted on an Intention-to-Treat (ITT) analysis data set. RESULTS: At the study endpoint, treatment with melatonin resulted in a considerably higher reduction in the mean NRS pain score in comparison with placebo (4.2 ± 1.83 vs. 2.9 ± 1.56; P-value < 0.001). In terms of treatment responders, a greater proportion of melatonin-treated patients satisfied the responder criterion than placebo-treated patients (63.5% vs. 43.1%). Melatonin also reduced pain-related sleep interference scores more than did placebo (3.38 ± 1.49 vs. 2.25 ± 1.26; P-value < 0.001). Further, at the endpoint, more improvement was also seen in terms of PGIC, CGIC, and Health-related QOL in patients treated with melatonin than placebo. Melatonin was also well tolerated. CONCLUSION: The present results showed that melatonin as an adjunct therapy to pregabalin might be helpful for use in patients with PDN. However, confirmation of these results requires further studies.

Efficacy and safety of sulforaphane for treatment of mild to moderate depression in patients with history of cardiac interventions: A randomized, double-blind, placebo-controlled clinical trial.

AIM: Depression has been recognized as one of the disorders associated with cardiac interventions such as percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG). In the present study, we evaluated the efficacy and safety of sulforaphane in treatment of depression induced by cardiac interventions. METHODS: After initial screening, 66 patients with previous history of at least one cardiac intervention and current mild to moderate depression were randomly assigned to two parallel groups receiving either sulforaphane (n = 33) or placebo (n = 33) for six successive weeks. Efficacy was assessed using the Hamilton Rating Scale for Depression (HAM-D) at baseline and week 2, 4, and 6. Safety of the treatments was checked during the trial period. RESULTS: Sixty participants completed the clinical trial (n = 30 in each group). Baseline demographic and clinical parameters were all similar among groups. Repeated measures analysis indicated that the sulforaphane group exhibited greater improvement in HAM-D scores throughout the trial (P < 0.001). Response to treatment (≥50% reduction in the HAM-D score) rate was higher in the sulforaphane group at trial endpoint (30% vs 6.67%, P = 0.042). Remission (HAM-D score ≤ 7) rate was also higher in the sulforaphane group; however, the difference was not significant (23.33% vs 3.33%, P = 0.052). Finally, no significant difference was observed between the two groups in terms of frequency of side effects. CONCLUSIONS: Sulforaphane could safely improve depressive symptoms induced by cardiac interventions. Further clinical trials with larger sample sizes and longer follow-up periods are warranted to confirm our results.

Influence of adjuvant Coenzyme Q10 on inflammatory and oxidative stress biomarkers in patients with bipolar disorders during the depressive episode.

Bipolar disorder (BPD) is a severe and chronic mental disease with high rates of social and functional disability. To explain the emergence and maintenance of BPD, increasing attention has been focused on dimensions of inflammation and oxidative stress (OTS). Coenzyme Q10 (CoQ10) is known for its anti-oxidant and anti-inflammatory effects; accordingly, the aim of the present study was to investigate, if compared to placebo, adjuvant CoQ10 might favorably impact on serum levels of inflammatory and OTS biomarkers in patients with BPD during their depressive phase. A total of 89 BPD patients, currently in a depressive episode were allocated by block randomization either to the adjuvant CoQ10 (200 mg/day) condition or to the placebo condition. At baseline and 8 weeks later at the end of the study, serum levels of total antioxidant capacity (TAC), total thiol groups (TTG), catalase activity (CAT), nitric oxide (NO), malondialdehyde (MDA), tumor necrosis factor-alpha (TNF-α), interlukin-6 (IL-6), and IL-10 were assessed. 69 patients completed the 8-week lasting study. Compared to baseline and to the placebo condition, serum levels of TTG and TAC significantly increased, and TNF-α, IL-10, and NO statistically decreased over time in the adjuvant CoQ10 condition. No statistically significant changes were observed for CAT, MDA, and IL-6. The pattern of results suggests that compared to placebo and over a time lapse of 8 weeks, adjuvant CoQ10 favorably impacted on OTS and inflammatory biomarkers in patients with BPD during the depressive episode. Thus, CoQ10 might be considered a safe and effective strategy for treatment of patients with BPD during their depressive phase.

Evaluating the Effect of Coenzyme Q10 Augmentation on Treatment of Bipolar Depression: A Double-Blind Controlled Clinical Trial.

BACKGROUND: Bipolar disorder (BPD) is a chronic and recurrent mood disorder characterized by episodes of mania, hypomania, and major depression. Based on available evidence, mitochondrial dysfunction, oxidative stress, and inflammation have important roles in the pathophysiology of bipolar depression. More specifically, it seems that coenzyme Q10 (CoQ10), a mitochondrial modulator, as well as an antioxidant and anti-inflammatory agent, might be effective in modulating these pathophysiological pathways. Accordingly, the aim of this study was to investigate whether and to what extent, compared with placebo, adjuvant CoQ10 might improve symptoms of depression in patients with BPD. METHODS: A total of 69 patients with BPD with a current depressive episode were randomly assigned either to the adjuvant CoQ10 (200 mg/d) or to the placebo group. Standard medication consisting of mood stabilizers and antidepressants was consistent 2 months prior and during the study. Depression severity for each patient was assessed based on the Montgomery-Asberg Depression Rating Scale scores at baseline, fourth week, and eighth week of the study. RESULTS: Symptoms of depression decreased over time in both groups. Compared with the placebo group, adjuvant CoQ10 to a standard medication improved symptoms of depression after 8 weeks of treatment. In addition, at the end of the study, it turned out that more responders were observed in the CoQ10 group, compared with the placebo group. CoQ10 had minimal adverse effects and was well tolerated. CONCLUSIONS: The present pattern of results suggests that among patients with BPD, compared with placebo, adjuvant CoQ10 probably because of its antioxidant and anti-inflammatory properties can improve symptoms of depression over a period of 8 weeks.

Delayed Myocardial Infarction Associated With Rituximab Infusion: A Case Report and Literature Review.

To report a case of delayed myocardial infraction after rituximab infusion. A 52-year-old woman with history of refractory idiopathic thrombocytopenic purpura had hypertension, seizure, and mild coronary artery disease and received rituximab; after 24 hours, she returned back with chest pain, nausea, and vomiting. Her electrocardiogram showed a ST-elevation in the II, III, aVF, and aVR lead and ST depression in I and aVL lead; after another complementary test, the myocardial infraction was confirmed. The patient was sent to the intensive care unit, and after 8-day hospitalization, she was discharged. Based on the Naranjo Probability Scale, the likelihood of rituximab-induced acute myocardial infarction in this case was probable. Rituximab is generally well tolerated; however, cardiovascular effects of this drug can be fatal. The side effects usually occur during or a short time after infusion; this case demonstrated that rituximab side effects may occur with delay. This case demonstrates, although a rare phenomenon, myocardial infraction may occur after 24 hours and clinicians should be aware of this fatal effect even after a period of time in patients receiving rituximab, especially in patients with history of coronary artery disease.

Evaluation of the safety and efficacy of direct oral anticoagulants compared with vitamin-k antagonists in the treatment of left ventricular thrombosis. A systematic review and meta-analysis.

BACKGROUND: Since the introduction of direct oral anticoagulants (DOACs) and their comparison with vitamin K antagonists (VKAs), conflicting results have been reported regarding the optimal treatment for left ventricular thrombosis (LVT). OBJECTIVES: In this meta-analysis, we intend to comprehensively evaluate the safety and efficacy of these treatments. METHODS: All clinical trials and cohorts that compared the efficacy or safety of VKAs with DOACs in the treatment of LVTs were systematically searched until April 15, 2023. RESULTS: The results of 32 studies with a pooled sample size of 4213 patients were extracted for meta-analysis. DOACs, especially rivaroxaban and apixaban, cause faster resolution, lower mortality, and fewer complications (SSE and bleeding events) than VKAs in the management of LVTs. CONCLUSION: Compared with VKAs, DOACs result in significantly faster (only rivaroxaban) and safer resolution of left ventricular thrombosis.

The miracle of IVUS for unforeseen stent thrombosis: A case report.

Stent thrombosis is a serious complication with high morbidity and mortality rates resulting in cardiac death or nonfatal myocardial infarction that occurs following stent placement during percutaneous coronary intervention (PCI). Stent underexpansion or malapposition are avoidable risk factors for stent thrombosis. Sufficient postdilation should be considered to mitigate this risk, especially with the guidance of intravascular ultrasound (IVUS). We present the case of a 60-year-old man developing a thrombotic lesion inside a stent 2 weeks after PCI for Non-ST-Segment Elevation Myocardial Infarction (NSTEMI), which was strongly related to stent underexpansion and malapposition. This case highlights the importance of IVUS in evaluating procedural success, particularly in assessing stent expansion and apposition.

Comparison of therapeutic effects of N-Acetylcysteine with pregabalin in improving the clinical symptoms of painful diabetic neuropathy: a randomized, double-blind clinical trial.

OBJECTIVES: Painful diabetic neuropathy (PDN) is highly prevalent and annoyingly in patients with diabetes. The aim of this study was to investigate the effects of oral N-acetylcysteine (NAC) compared to pregabalin in PDN. METHODS: One hundred two eligible patients with type 2 diabetes and PDN were randomly recievied pregabalin (150 mg/day) or N-Acetylcysteine (NAC) (600 mg/ twice a day) for 8 weeks. Mean pain score, Sleep interference score (SIS), Patient Global Impression of Change (PGIC), Clinical Global Impression of Change (CGIC), and also, serum levels of total antioxidant capacity (TAC), total thiol groups (TTG), catalase activity (CAT), nitric oxide (NO), and malondialdehyde (MDA) were assessed at baseline and at the end of the study. RESULTS: NAC was well tolerated in all patients. The decrease in mean pain scores and increase in SIS was similar between two groups. More improvement in PGIC and CGIC from the baseline was reported in NAC group. NAC, significantly, decreased serum levels of MDA, and NO, but increased TAC, TTG, and CAT. Pregabalin, significantly, decreased serum levels of MDA, and NO and increased TAC. DISCUSSION: NAC is efficacious in alleviate symptoms of PDN which is probably related to its antioxidant effects. TRIAL REGISTRATION: The research protocol received approval from the Ethics Committee of Hamadan University of Medical Sciences (IR.UMSHA.REC.1397.137). The trial registry URL and number in Iranian Registry of Clinical Trials (IRCT): https://www.irct.ir/trial/33313 , IRCT20180814040795N2 (Registration date: 2019-01-21, Retrospectively registered).

Successful management of a delayed presentation of traumatic descending thoracic aorta pseudoaneurysm: a literature review based on a case report.

BACKGROUND: Blunt traumatic aortic injury (BTAI) is the second leading cause of death due to traumas in young patients. The primary presentation might be chest or interscapular pain, difficulty in breathing, and, in severe cases, hypotension. Considering the rapid deterioration of these patients' clinical conditions, prompt diagnosis and treatment initiation are crucial. In these injuries, the most involved parts of the aorta are the isthmus (distal to the left subclavian artery) and the descending part in the thorax. Therefore, the main diagnostic strategies include transthoracic echocardiography, CT angiography, and endovascular diagnostic approaches. Case presentation The patient was a 19-year-old male presenting with the symptoms of chest pain, dyspnea, and extremities excruciating pain after a car turnover. The initial evaluation showed no abnormal cardiovascular finding except bilateral hemothorax, addressed with chest tubes. Twelve hours later, when the patient was under observation for orthopedic surgeries, his chest pain and dyspnea started, and TTE and CTA showed a grade three descending aneurysm of the aorta. The patient was treated immediately with an endovascular procedure of stent implantation. A delayed debranching surgery was also performed, which resulted in desirable outcomes and uneventful follow-up. CONCLUSION: Although open thoracic surgery is the main and almost the only option for treating aneurysms of the aorta in hemodynamically unstable patients, the endovascular procedure has shown superior outcomes in selected patients with appropriate anatomy. Debranching surgery, which can be done simultaneously or with delay after the initial procedure, has proven protective against thromboembolic cerebral events. CLINICAL KEY POINT: Patients with an aneurysm of the aorta should be transported to a medical center with a multidisciplinary team for an urgent evaluation and treatment. The initial resuscitation and diagnosis are challenging, considering the fatal nature of these injuries, and the selection of the treatment is based on the patient's clinical condition and evaluated anatomy in cardiovascular imaging.

Iatrogenic combined common iliac and lateral sacral artery perforation during coronary angiography: A case report and review of literature.

Key Clinical Message: Arterial rupture is one of the rare but known and devastating complications of the angiogram, which can ultimately lead to loss of limb and life. Therefore, it is recommended that this complication be included in the consent form and that the operator and the logistics team be prepared for this scenario. Moreover, categorizing the patients based on risk factors to be more cautious during the procedure for high-risk patients can be considered a reasonable strategy. Abstract: One of the rare but lethal complications of femoral artery catheterization for coronary angiography is arterial rupture, which can cause a range of negligible to massive retroperitoneal hemorrhage. This case presents a woman with unstable angina who underwent coronary catheterization. After arterial sheath placement, extravasation of blood from the right common iliac and lateral sacral arteries was seen, a diagnosis that has been reported rarely before. The bleeding was controlled with balloon inflation in the lateral sacral artery and a stent graft implantation in the right common iliac artery. The patient remained asymptomatic during the procedure and the short- and long-term follow-up. Interventional cardiologists and radiologists who access the femoral artery for any procedure should be aware of this possible event. Sometimes, this situation manifests with nonspecific symptoms such as weakness, lethargy, and pallor. Moreover, more logistical preparation and training are needed to overcome these unexpected conditions.

Impact of Clinical Pharmacist-conducted Medication Reconciliation at Admission and Discharge on Medication Safety in Patients Hospitalized with Acute Decompensated Heart Failure.

BACKGROUND: Most studies have focused on the impact of medication reconciliation on one of the points of hospital admission or discharge. In this study, we aimed to investigate the impact of medication reconciliation at both admission and discharge on medication safety in patients hospitalized with acute decompensated heart failure. METHODS: This was a prospective, single-center, cohort study conducted in a tertiary care cardiovascular hospital from October 2022 to March 2023 on patients hospitalized with acute decompensated heart failure. Patients were considered eligible if they were taking at least five chronic medications prior to hospital admission. Medication reconciliation was carried out for the study patients by a clinical pharmacy team both at admission and discharge. Further, the study patients also received comprehensive discharge counseling as well as post-discharge follow-up and monitoring. RESULTS: Medication reconciliation was applied for 129 patients at admission and 118 of them at discharge. The mean time needed for medication reconciliation presses was 32 min per patient on admission and 22min per patient on discharge. Unintentional medication discrepancies were relatively common both at admission and discharge in the study participants, but compared to admission, discrepancies were less frequent at discharge (178 versus 72). Based on the consensus review, about 30% of identified errors detected at both admission and discharge were judged to have the potential to cause moderate to severe harm to the patient, and most of the clinical pharmacists' recommendations on unintended discrepancies were accepted by physicians and resulted in changes in medication orders (more than 80%). Further, the majority of the participants were 'very satisfied' or 'satisfied' with the clinical pharmacy services provided to them during hospitalization and after hospital discharge (89.90%). CONCLUSIONS: Our results demonstrated that heart failure patients are vulnerable to medication discrepancies both at admission and discharge and implementing a comprehensive medication reconciliation by clinical pharmacists could be helpful in improving medication safety in these patients.
