RESUMO

BACKGROUND: The pandemic coronavirus disease 2019 (COVID-19) has been associated with substantial mortality worldwide. Efforts have continued to find an effective treatment for COVID-19. In vitro activity of interferon (IFN) subtypes has been shown against the SARS-CoV and MERS-CoV. Furthermore, the superiority of IFN-ß over IFN-α2b and IFN-α2a has been demonstrated in MERS treatment. Early studies showed a low plasma level of IFNs in the peripheral blood or lungs of patients with severe COVID-19. This study assessed the effects of IFN-alpha-2a and -beta-1a on the prognosis of patients with covid-19 infection. METHODS: We conducted a triple-blind randomized clinical trial on adult patients with moderate to severe COVID-19 from April 2021 to June 2021. The patients were diagnosed based on clinical and laboratory findings and randomly assigned into four groups (A, B, C, and D) using the envelope allocation method. Patients in group A received IFN ß-1a; group B received IFN ß-1a placebo; group C received IFN α-2a, and group D was treated with IFN α-2a placebo. All patients concomitantly received the national protocol medications as well. RESULTS: A total of 95 eligible patients were randomly assigned into groups. National Early Warning Score 2 (NEWS2) index showed significant differences between groups only on the first day of admission (p-value = 0.001). CT scan scores on the first and tenth days slightly improved, although they were not statistically significant. Duration of hospitalization and hospital discharge did not significantly differ among all treated groups (Table 1). Mortality rates showed no significant statistical difference between the groups. However, viral clearance significantly accelerated in the patients receiving IFN ß-1a or IFN α-2a (p < 0.05). CONCLUSION: It seems that IFN α-2a and IFN ß-1a are ineffective in treating COVID-19 patients. Further randomized clinical trials with large sample sizes are needed to estimate the effects of IFN α-2a or IFN ß-1a on the outcomes of COVID-19 disease.

RESUMO

Myocardial infarction without ST-segment elevation (NSTEMI) is considered an inflammatory disorder associated with a high mortality rate worldwide. High-sensitivity C-reactive protein (hs-CRP) is an important inflammatory marker for NSTEMI and related to cardiovascular events. Colchicine, as a potent anti-inflammatory drug, is frequently prescribed for the treatment of gout and pericarditis. The present study aimed to evaluate the effects of colchicine, as an anti-inflammatory drug, on hs-CRP levels in NSTEMI patients. We performed a randomised, double-blind, placebo-controlled trial involving 150 NSTEMI patients referred to Imam Reza and Ghaem Hospitals affiliated to Mashhad University of Medical Sciences. The patients were randomised to receive colchicine or placebo along with optimal medications for 30 days. The hs-CRP was measured at the admission and end of the study. Our results revealed that, in both colchicine and placebo groups, hs-CRP levels were significantly mitigated in NSTEMI patients compared to baseline (P < 0.001). However, the decreasing properties of colchicine on hs-CRP levels were remarkably stronger than placebo following the 30 days of treatment (P < 0.001). Nevertheless, neither colchicine nor placebo treatment could achieve hs-CRP levels lower than 2 mg/L. There were no significant differences between the effects of colchicine on the hs-CRP decrease in diabetic and non-diabetic, male and female, and normal and preserved LVEF NSTEMI patients. It can be concluded that colchicine may prevent the disease progression and succedent cardiovascular events in NSTEMI patients by attenuating the inflammation.

RESUMO

BACKGROUND: There is controversial evidence about the effect of cerebellar low-frequency stimulation in patients with essential tremor (ET). OBJECTIVES: In this study we assessed safety and effectiveness of 1 Hz (low-frequency) cerebellar repetitive transcranial magnetic stimulation (rTMS) on tremor severity in patients with essential tremor in a sham-controlled crossover trial. METHODS: A total of 23 patients assigned into two groups to receive either sham (n = 10) or rTMS (n = 13) treatment, with crossing over after a two-month washout period. Intervention consisted of 900 pulses of 1 Hz rTMS at 90% resting motor threshold or the same protocol of sham stimulation over each cerebellar hemisphere for 5 consecutive days. Tremor severity was assessed by Fahn-Tolosa-Marin (FTM) scale at baseline and at days 5, 12 and 30 after intervention. The FTM consists of 3 subscales including tremor severity rating, performance of motor tasks, and functional disability. Carry-over and treatment effects were analyzed using independent samples t-test. RESULTS: There was no significant improvement in the total FTM scores in rTMS compared to the sham stimulation on day 5 (p = 0.132), day 12 (p = 0.574), or day 30 (p = 0.382). Similarly, FTM subscales, including tremor severity rating, motor tasks, and functional disability did not improve significantly after rTMS treatment. Mild headache and local pain were the most frequent adverse events. CONCLUSION: Although cerebellar rTMS seems to have acceptable safety when used in ET patients, this study could not prove any efficacy for it in reduction of tremor in these patients. Larger studies are needed to evaluate efficacy of this therapeutic intervention and to provide evidence about the optimal stimulation parameters.

RESUMO

BACKGROUND: Aluminium phosphide (ALP) or rice pill is a substance used in developing countries due to its low cost as pesticides. The availability of this substance has been lead to an increased rate of the use of this toxic inorganic compound for suicide. Complications are considered to be dose-related toxicity and hospitalisation time, varying from hemodynamic disorder, hypoglycemia, hyperglycemia, shock, cardiotoxicity, pulmonary and renal failures. The consumption of this substance is one of the major causes of mortality due to heart arrhythmia. QT dispersion represents a regional difference in ventricular repolarisation and electrical instability of the heart. AIM: The purpose of this study was to investigate the effect of ALP poisoning on QT dispersion. METHODS: In this study, 70 patients with ALP poisoning were enrolled, and 10 patients were excluded due to the exclusion criteria. QT dispersion rate was calculated in 60 patients using the standard electrocardiography at the time of referral. The above data were compared with the control group, which included 40 subjects with normal coronary angiography, and without cardiovascular risk factors. RESULTS: The findings presented herein indicated a significant correlation between QT dispersion and control group (P < 0.0.5). There was a significant relationship between the severity of acidosis and the patient's tablets -taking a number (P < 0.05). However, there was no relationship between QT dispersion with the severity of acidosis and mortality in patients. CONCLUSION: Because there is no CAD risk factor in the population, it can be concluded that increase in QT dispersion in these individuals can be due to ALP poisoning; nevertheless, this is not considered to be a factor in increasing the morbidity of these patients.

RESUMO

OBJECTIVE: Mycobacterium marinum causes a rare cutaneous disease known as fish tank granuloma (FTG). The disease manifestations resemble those associated with Cutaneous Leishmaniasis (CL). The aim of this study was to determine whether FTG was the cause of cutaneous lesions in patients who were referred to the Parasitology laboratory of Imam Reza Hospital in Mashhad to be investigated for CL. MATERIALS/METHODS: One hundered patients, clinically diagnosed with CL between April 2014 and March 2015, were included in this study. Ziehl-Neelsen staining was performed to identify acid-fast Mycobacterium in addition to bacterial cultures using Löwenstein-Jensen medium. Skin lesion samples were also collected and kept on DNA banking cards for PCR testing. RESULTS: Twenty-nine of the 100 individuals with skin lesions, and therefore suspected of suffering from CL, tested positive for Mycobacterium marinum by PCR. Of these, 21 (72.4%) were male and 8(27.6%) were female. In 97% of these cases the lesions were located on hands and fingers. These patients had a history of manipulating fish and had been in contact with aquarium water. A sporotrichoid appearance was observed in 58.6% of the patients with mycobacterial lesions; 67% of patients had multiple head appearance. CONCLUSION: Patients suspected to have CL and who test negative for CL could be affected by FTG. Therefore, after obtaining an accurate case history, molecular diagnosis is recommended for cases that give a negative result by conventional methods.

RESUMO

Cardiovascular disease is one of the most important causes of morbidity and mortality in the world. Treatment in most patients is percutanseous coronary intervention. One of new generation drug-eluting stent (DES) is Sirolimus Eluting Stent. The current study was aimed to investigate the clinical outcomes and complications of treatment with supraflex stent during one year follow up in patients with coronary artery disease. This cross-sectional study was performed on patients with myocardial ischemia who were candidate for coronary angioplasty between 2017-2018 in Imam Reza Hospital, Mashhad, Iran.. Patients were followed for four primary end points including Target lesion revascularization (TLR), stent thrombosis (ST), myocardial infarction (MI) and cardiac death (CD) for one year. Descriptive data were analyzed by Freidman at a significance level of 0.05. A total of 287 patients were enrolled in the study. There was no TLR, MI, ST and CD records in the one month follow up. Six months follow up demonstrated three TLR patients and three MI patients, but no ST and death were reported. After one year follow up, three cases of CD and four ST cases were found in patients treated with supraflex stent. Based on the Freidman test, the highest rate of TLR was revealed in a six-month follow-up when comparing with one-month and twelve-month follow-up (p = 0.05). No significant relationship was found between the other cases. The most common complications associated with supraflex stent were TLR and MI in six-month follow-up. The most likely occurrence of CD and ST were found in one year follow up.

RESUMO

OBJECTIVE: The aim of this study was to investigate the impact of perioperative administration of N-acetylcysteine, selenium and vitamin C on the incidence and outcomes of acute kidney injury after off-pump coronary bypass graft surgery. METHODS: 291 patients requiring elective off-pump coronary bypass graft surgery were randomized to receive either N-acetylcysteine, vitamin C and selenium 600 mg, 1500 mg, 0.5 mg, and nothing orally twice a day, respectively, from the day before to 2 days after surgery. They were assessed for the development of acute kidney injury using Acute Kidney Injury Network criteria, time of onset, its severity and duration, duration of mechanical ventilation, intensive care unit and hospital length of stay, and in-hospital mortality. RESULTS: 272 patients completed the study. The total incidence of acute kidney injury was 22.1% (n=60) with 14 (20.9%), 15 (22.1%), 21 (31.8%), and 10 (14.1%) patients in the vitamin C, NAC, selenium, and control groups, respectively (P=0.096). We did not register significant differences in the incidence, the time of occurrence, the severity and the duration of acute kidney injury, as well as the duration of mechanical ventilation, the intensive care unit and hospital length of stay, and the in-hospital mortality among the four groups. CONCLUSION: We found that perioperative administration of N-acetylcysteine, vitamin C and selenium were not effective in preventing acute kidney injury and associated morbidity and mortality after off-pump coronary bypass graft surgery.

RESUMO

AIM: Peak atrial longitudinal strain (PALS) is used to evaluate left atrium (LA) function in patients with mitral stenosis (MS), before and after percutaneous transmitral commissurotomy (PTMC) and mitral valve replacement (MVR). METHODS: Patients with severe symptomatic MS, who were referred to our echocardiographic laboratory for a diagnostic examination before cardiac surgery or PTMC from October of 2014 to October of 2015, were included in the study. RESULT: The peak systolic global LA strain improved post-PTMC (P < 0.001) and post-MVR (P = 0.012). This difference was statistically highly significant. CONCLUSION: PALS is impaired in patients with severe symptomatic MS and improved acutely after treatment and may be a good indicator of LA function and may predict the right time for intervention on mitral valve.

RESUMO

Apoptosis is a universal cellular defense mechanism against viral infection. Curcumin, an anti-inflammatory phytochemical, induces apoptosis through mitochondrial and receptor-mediated pathways, as well as activation of caspase cascades. Here, we investigated the impact of supplementation with curcumin on the expression of a panel of apoptosis- and cytotoxicity-related genes in patients suffering from HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP), a progressive demyelinating neuroinflammatory disease caused by HTLV-1 infection. Twenty-one HAM/TSP patients enrolled in this study. Curcumin nanomicelles (80mg/day, orally) were administered once a day for 12 weeks. The mRNA levels of total Fas (tFas), membrane-bound Fas (mFas), Fas-Ligand (FasL), TNF-related apoptosis-inducing ligand (TRAIL), perforin, granzyme A, granzyme B and granulysin were analyzed before and after treatment in peripheral blood lymphocytes. Protein levels of Fas, FasL, TRAIL and granulysin were also measured in serum using ELISA. Curcumin supplementation inhibited FasL mRNA production and up-regulated the expression of pro-apoptotic molecules granzyme A (at the mRNA level) and granulysin (at the protein level), suggesting degranulation of granulysin-bearing cells following curcumin supplementation. Conversely, Curcumin did not affect Fas, TRAIL, perforin, granzyme B at the mRNA level, and anti-apoptotic molecules sFas, sFasL and sTRAIL at the protein level. The present results suggest that curcumin supplementation increases cytotoxicity-related molecules granzyme A and granulysin in patients with HAM/TSP.

RESUMO

BACKGROUND: Bedside teaching is a patient-based teaching method in medical education. The present study has been conducted with the aim of investigating the quality of bedside teaching in the internal wards of Qaem and Imam Reza Educational Hospitals. METHODS: This study follows a mixed qualitative-quantitative approach using checklists on educational clinical rounds in Imam Reza and Qaem Hospitals in Mashhad. In the first stage consisting of qualitative study, the parts related to the quality of bedside teaching were recognized and a checklist was designed in three domains of patient comfort (8 questions), targeted teaching (14 questions) and group dynamics (8 questions), and its reliability and validity were verified. In the next step, data were collected and then analyzed using SPSS 16 software through statistical techniques of independent t-test, one-way ANOVA and variance analysis. RESULTS: In total, 113 educational rounds were investigated in this study. Among them, 59 (52.2%) and 54 (47.8%) educational rounds have been investigated in Imam Reza and Qaem Hospitals, respectively. The average total score of bedside teaching was 180.8 out of 300 in the internal wards of both Imam Reza and Qaem Hospitals. CONCLUSION: The results of this study showed that generally the quality of bedside teaching in Imam Reza and Qaem Hospitals of Mashhad is low according to the qualitative standards considered in this study. Holding educational workshops along with more familiarity of the professors with effective bedside teaching strategies could be effective in improving the quality of educational rounds.

RESUMO

OBJECTIVES: Currently little research exists examining self-mutilation (SM) in samples of forensic referrals. The present study provides a comprehensive review on the frequency, etiology, and morphologic characteristics of self-inflicted injuries in a sample of outpatients' forensic referrals. METHODS: In a prospective cross-sectional study, during 3 years, we examined 9874 outpatients' forensic referrals and found 1248 SM cases in Ghouchan (an urban and suburban area of Iran). RESULTS: Based on forensic medical examinations, it was found that 12.6% of all outpatients' forensic referrals had engaged in SM behavior at sometime. Males had significantly higher rates of SM than females (76.9 vs. 23.1%, respectively). The mean age was found to be significantly lower in patients with SM (23.6 +/- 8.5) than patients without SM (40.0 +/- 10.5) (P < 0.001). Rate of being single and unemployed was higher in the SM group (58.2, 56.1%, respectively) than in the group without SM (19.1, 22.8%, respectively). Superficial cuts and scratches were found to be the most common type of SM (79.5%), followed by bruises (10.8%), burns (3.4%), deep cuts (3.2%), fractures (0.6%), and other miscellaneous injuries (2.5%). Upper extremities including forearms, wrists, and arms opposite the dominant hand were the most common areas of injury. CONCLUSIONS: Nonsuicidal self-injury, the deliberate-direct destruction of body tissue without suicidal intent is a relatively common event in forensic referrals. It is very important to distinguish between this and other types from forensic point of view. Forensic practitioners must be expert and trained for this purpose.
