RESUMEN
Objective: The objective of this study was to determine the role of Iranian herbal Zofa® syrup in improving the clinical symptoms of patients with COVID-19. Materials and Methods: This randomized clinical trial was conducted on 105 patients with COVID-19. Patients were randomly assigned to the intervention (n=35) group (received 10 ml of Zofa® syrup every 8 hours/seven days plus standard treatment) or the control (n=70) group (received only standard treatment). Assessments were performed before and after treatment. Results: The groups were comparable regarding age (p=0.980), gender (p=0.584), comorbidities (p=0.318), or drug history (p=0.771). There was no difference between patients' recovery status at the time of discharge (p=0.327) or two weeks post-discharge (p=0.165) in the intervention and control groups. No patient was hospitalized to the intensive care unit (ICU) for supplemental oxygen therapy and no patient died in the intervention group. However, in the control group, three (4.5%) patients were transferred to the ICU, and two (3.03%) patients died. Conclusion: Considering the better recovery status of the patients at the time of discharge and the absence of patient deaths in the intervention group, more additional studies are needed to confirm these findings and elucidate the role of Zofa® in COVID-19.
RESUMEN
OBJECTIVE: Haemorrhoids are one of the most common gastrointestinal and anal diseases. In olive oil and honey propolis, flavonoids have beneficial effects on improving vascular function and decreasing vascular resistance. In this study, we aimed to produce a combination of these two substances in the form of lotions and assess their healing and side effects in comparison with routine treatment, anti-haemorrhoid ointment (containing hydrocortisone and lidocaine). DESIGN: In this randomised clinical trial study, 86 patients with grade 2 or more haemorrhoid degrees, diagnosed by colonoscopy, were divided into two groups, the case (n=44) and control (n=42). The case group was treated with flavonoid lotion, and the control group was treated with anti-haemorrhoid ointment two times per day for 1 month. Patients were followed weekly with history and physical examination. The data of the two groups were collected before and after the intervention and statistically analysed. RESULTS: Post-treatment reduction in haemorrhoid grade was significant in the case group (p=0.02). This ratio was insignificant in the control group (p=0.139). Flavonoid lotion (p<0.05) significantly reduced the signs and symptoms of haemorrhoids more than anti-haemorrhoid ointment. CONCLUSION: According to the results, flavonoid lotion can be an excellent alternative to topical chemical drugs, such as anti-haemorrhoid ointment, in treating haemorrhoid disease. Besides its effectiveness and safety, it can be easily manufactured and widely available to patien.

RESUMEN
Various severe acute respiratory syndrome coronavirus 2 vaccines with different platforms have been administered worldwide; however, their effectiveness in critical cases of COVID-19 has remained a concern. In this national cohort study, 24 016 intensive care unit (ICU) coronavirus disease-2019 (COVID-19) admissions were included from January to April 2022. The mortality and length of ICU stay were compared between the vaccinated and unvaccinated patients. A total of 9428 (39.25%) patients were unvaccinated, and 14 588 (60.75%) patients had received at least one dose of the vaccine. Compared with the unvaccinated, the first, second, and third doses of vaccine resulted in 8%, 20%, and 33% lower risk of ICU mortality in the adjusted model, with risk ratio (RR): 0.92, 95% confidence interval (CI): 0.84-1.001, RR: 0.80, 95% CI: 0.77-0.83, and RR: 0.67, 95% CI: 0.64-0.71, respectively. The mean survival time was significantly shorter in the unvaccinated versus the fully vaccinated patients (hazard ratio [HR]: 0.84, 95% CI: 0.80-0.88); p < 0.001). All vaccine platforms successfully decreased the hazard of ICU death compared with the unvaccinated group. The duration of ICU stay was significantly shorter in the fully vaccinated than in unvaccinated group (MD, -0.62, 95% CI: -0.82 to -0.42; p < 0.001). Since COVID-19 vaccination in all doses and platforms has been able to reduce the risk of mortality and length of ICU-stay, universal vaccination is recommended based on vaccine availability.

BACKGROUND: The coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to plague the world. While COVID-19 is asymptomatic in most individuals, it can cause symptoms like pneumonia, ARDS (acute respiratory distress syndrome), and death in others. Although humans are currently being vaccinated with several COVID-19 candidate vaccines in many countries, however, the world still is relying on hygiene measures, social distancing, and approved drugs. RESULT: There are many potential therapeutic agents to pharmacologically fight COVID-19: antiviral molecules, recombinant soluble angiotensin-converting enzyme 2 (ACE2), monoclonal antibodies, vaccines, corticosteroids, interferon therapies, and herbal agents. By an understanding of the SARS-CoV-2 structure and its infection mechanisms, several vaccine candidates are under development and some are currently in various phases of clinical trials. CONCLUSION: This review describes potential therapeutic agents, including antiviral agents, biologic agents, anti-inflammatory agents, and herbal agents in the treatment of COVID-19 patients. In addition to reviewing the vaccine candidates that entered phases 4, 3, and 2/3 clinical trials, this review also discusses the various platforms that are used to develop the vaccine COVID-19.

The aim of this study was to evaluate the effect and safety of N-acetylcysteine (NAC) inhalation spray in the treatment of patients with coronavirus disease 2019 (COVID-19). This randomized controlled clinical trial study was conducted on patients with COVID-19. Eligible patients (n = 250) were randomly allocated into the intervention group (routine treatment + NAC inhaler spray one puff per 12 h, for 7 days) or the control group who received routine treatment alone. Clinical features, hemodynamic, hematological, biochemical parameters and patient outcomes were assessed and compared before and after treatment. The mortality rate was significantly higher in the control group than in the intervention group (39.2% vs. 3.2%, p < 0.001). Significant differences were found between the two groups (intervention and control, respectively) for white blood cell count (6.2 vs. 7.8, p < 0.001), hemoglobin (12.3 vs. 13.3, p = 0.002), C-reactive protein (CRP: 6 vs. 11.5, p < 0.0001) and aspartate aminotransferase (AST: 32 vs. 25.5, p < 0.0001). No differences were seen for hospital length of stay (11.98 ± 3.61 vs. 11.81 ± 3.52, p = 0.814) or the requirement for intensive care unit (ICU) admission (7.2% vs. 11.2%, p = 0.274). NAC was beneficial in reducing the mortality rate in patients with COVID-19 and inflammatory parameters, and a reduction in the development of severe respiratory failure; however, it did not affect the length of hospital stay or the need for ICU admission. Data on the effectiveness of NAC for Severe Acute Respiratory Syndrome Coronavirus-2 is limited and further research is required.

The current and ongoing conflict imposed in Gaza has led to severe environmental challenges in Gaza, resulting in a health crisis that demands immediate attention and intervention. A comprehensive study has evaluated the pressing mental health, water and sanitation, access to healthcare, and infectious disease challenges plaguing the region. Mental health issues, particularly among children and adolescents, have surged in the wake of the conflict, with trauma-related symptoms expected to persist. The water and sanitation crises pose severe public health hazards, with an overwhelming majority of water unfit for consumption and escalating infectious diseases. Shortages of medicines, fuel, and breakdowns have profoundly affected access to healthcare in healthcare facilities, significantly impacting women and girls. The academic society is responsible for conducting research, providing education, and training, and advocating for policy changes. At the same time, the united nation's (UN) role is vital in providing aid, advocating for policy changes, and monitoring human rights and health situations. Urgent action is imperative to stabilize the environmental and health impacts and allow humanitarian aid into Gaza to alleviate the severe health problems. This study underlines the critical need for international support and intervention to address the multifaceted health crises in Gaza and prevent further deterioration.
RESUMEN
We performed a review study according to recent COVID-19 vaccines' real-world data to provide comparisons between COVID-19 vaccines regarding their relative efficacy. Although most vaccine platforms showed comparable effectiveness and efficacy, we highlight critical points and recent developments generated in studies that might affect vaccine efficacy including population-dependent effects of the vaccine (transplantation, adiposity, and specific comorbidities, as well as older age, male sex, ethnicity, and prior infection), vaccine type, variants of concern (VOC), and an extended vaccine schedule. Owing to these factors, community-based trials can be of great importance in determining vaccine effectiveness in a systematic manner; thus, uncertainty remains regarding vaccine efficacy. Long immune protection of vaccination with BNT162b2 or ChAdOx1 nCoV-19 has been demonstrated to be up to 61 months and 5-12 months after the previous infection, and boosting infection-acquired immunity for both the first and second doses of the BNT162b2 and ChAdOx1 nCoV-19 vaccines was correlated with high and durable protection. However, large cohort and longitudinal studies are required for the evaluation of immunity dynamics and longevity in unvaccinated, vaccinated, and infected individuals, as well as vaccinated convalescent individuals in real-world settings. Regarding the likelihood of vaccine escape variants evolving, an ongoing examination of the protection conferred against an evolving virus (new variant) by an extended schedule can be crucial.

Clinical observations have shown the risk of cardiovascular disease during asthmatic changes. Whether and how asthma causes heart failure is the subject of debate. Here, we aimed to investigate the possibility of cardiomyocyte mitophagy in a rat model of asthma. Twelve mature Wistar rats were randomly allocated into the Control and Asthmatic rats (n = 6). To induce asthma, ovalbumin was injected intraperitoneally on days 1 and 8 and procedure followed by nebulization from days 14 to 32. After 2 weeks, we performed the pathological examination of both lungs and heart using Hematoxylin-Eosin staining. Real-time PCR analysis was used to measure the expression of mitophagic factors, such as Optineurin, Pink1, and mitofusin 1 and 2. Typical changes like increased inter-alveolar septa thickness and interstitial pneumonia were evident in asthmatic lungs. In cardiac tissue, slight inflammatory response, and hydropic degeneration with an eosinophilic appearance were detected in the cytoplasm of cardiomyocytes. Real-time PCR analysis showed mitophagic response in pulmonary and cardiac tissues via upregulation of mitophagy-related genes like Optineurin and Pink-1 in asthmatic lungs and hearts compared to the control group (p < 0.05). Likewise, asthmatic changes increased the expression of genes associated with mitochondrial fusion in the lungs and heart. The expression of mitofusin1 and 2 was significantly increased following inflammatory response in pulmonary and cardiac tissues (p < 0.05). Our findings showed the expression of certain factors related to mitophagy during chronic asthmatic conditions. The findings open a new avenue in the understanding of cardiomyocyte injury during asthma.

Recently, circular RNAs (circRNAs) have appealed to a growing interest due to their abundant expression and potential functions in cancer development. The most biological function of circRNAs may include acting as a sponge for miRNAs and proteins in different physio/pathological conditions. CircRNAs promote cancer progression by regulating several procedures such as growth, invasion, metastasis, angiogenesis, and drug resistance. Emerging evidence has shown that circRNAs frequently have tumor-specific expression, proposing these molecules serve as diagnostic and prognostic cancer biomarkers. Furthermore, circRNAs may be used as a potential target for the treatment of cancers as they can sponge oncogenic miRNAs and proteins. Exosomes, a subtype of extracellular vesicles mediate intercellular communication, contain circRNAs and deliver them to target cells inducing cancer development through different signaling pathways. Exosomal circRNAs may serve as a diagnostic and prognostic biomarker for cancers. Targeting exosomes may represent novel approaches for the treatment of cancers through using them as cell-free therapy and drug-delivery system and inhibiting their biogenesis and distribution. However, research on circRNAs biology is advancing and some concerns such as technical issues in the characterization and analysis of circRNAs along with biological understanding gaps necessary to be considered to transfer this undeveloped field to the vanguard of clinical studies. In this review, we discuss the existing information on the formation of circRNA and its roles in the tumor as a biomarker and treatment target. Furthermore, we describe tumor-derived exosomes enclosed circRNAs and their possible roles in cancer development and their potential as biomarkers and therapeutic approaches.

Background: There is a risk of novel mutations of SARS-CoV-2 that may render COVID-19 resistant to most of the therapies, including antiviral drugs and vaccines. The evidence around the application of therapeutic plasma exchange (TPE) for the management of critically ill patients with COVID-19 is still provisional, and further investigations are needed to confirm its eventual beneficial effects. Aims: To assess the effect of TPE on the risk of mortality in patients with COVID-19-associated pneumonia, using three statistical procedures to rule out any threats to validity. Methods: We therefore carried out a single-centered retrospective observational non-placebo-controlled trial enrolling 73 inpatients from Baqiyatallah Hospital in Tehran (Iran) with the diagnosis of COVID-19-associated pneumonia confirmed by real-time polymerase chain reaction (RT-qPCR) on nasopharyngeal swabs and high-resolution computerized tomography chest scan. These patients were broken down into two groups: Group 1 (30 patients) receiving standard care (corticosteroids, ceftriaxone, azithromycin, pantoprazole, hydroxychloroquine, lopinavir/ritonavir), and Group 2 (43 patients) receiving the above regimen plus TPE (replacing 2 l of patients' plasma by a solution, 50% of normal plasma, and 50% of albumin at 5%) administered according to various time schedules. The follow-up time was 30 days and all-cause mortality was the endpoint. Results: Deaths were 6 (14%) in Group 2 and 14 (47%) in Group 1. However, different harmful risk factors prevailed among patients not receiving TPE rather than being equally split between the intervention and control group. We used an algorithm of structural equation modeling (of STATA) to summarize a large pool of potential confounders into a single score (called with the descriptive name "severity"). Disease severity was lower (Wilkinson rank-sum test p < 0.001) among patients with COVID-19 undergoing TPE (median: -2.82; range: -5.18; 7.96) as compared to those not receiving TPE (median: -1.35; range: -3.89; 8.84), confirming that treatment assignment involved a selection bias of patients according to the severity of COVID-19 at hospital admission. The adjustment for confounding was carried out using severity as the covariate in Cox regression models. The univariate hazard ratio (HR) of 0.68 (95%CI: 0.26; 1.80; p = 0.441) for TPE turned to 1.19 (95%CI: 0.43; 3.29; p = 0.741) after adjusting for severity. Conclusions: In this study sample, the lower mortality observed among patients receiving TPE was due to a lower severity of COVID-19 rather than the TPE effects.
RESUMEN
For successful translation of targeting nanomedicines from bench to bedside, it is vital to address their most common drawbacks namely rapid clearance and off-target accumulation. These complications evidently originate from a phenomenon called "protein corona (PC) formation" around the surface of targeting nanoparticles (NPs) which happens once they encounter the bloodstream and interact with plasma proteins with high collision frequency. This phenomenon endows the targeting nanomedicines with a different biological behavior followed by an unexpected fate, which is usually very different from what we commonly observe in vitro. In addition to the inherent physiochemical properties of NPs, the targeting ligands could also remarkably dictate the amount and type of adsorbed PC. As very limited studies have focused their attention on this particular factor, the present review is tasked to discuss the best simulated environment and latest characterization techniques applied to PC analysis. The effect of PC on the biological behavior of targeting NPs engineered with different targeting moieties is further discussed. Ultimately, the recent progresses in manipulation of nano-bio interfaces to achieve the most favorite therapeutic outcome are highlighted.

Cardiovascular disease is one of the leading causes of mortality globally. Atherosclerosis is an important step towards different types of cardiovascular disease. The role of oxidized low-density lipoprotein (oxLDL) in the initiation and progression of atherosclerosis has been thoroughly investigated in recent years. Moreover, clinical trials have established that diabetic patients are at a greater risk of developing atherosclerotic plaques. Hence, we aimed to review the clinical and experimental impacts of various classes of antidiabetic drugs on the circulating levels of oxLDL. Metformin, pioglitazone, and dipeptidyl peptidase-4 inhibitors were clinically associated with a suppressive effect on oxLDL in patients with impaired glucose tolerance. However, there is an insufficient number of studies that have clinically evaluated the relationship between oxLDL and newer agents such as agonists of glucagon-like peptide 1 receptor or inhibitors of sodium-glucose transport protein 2. Next, we attempted to explore the multitude of mechanisms that antidiabetic agents exert to counter the undesirable effects of oxLDL in macrophages, endothelial cells, and vascular smooth muscle cells. In general, antidiabetic drugs decrease the uptake of oxLDL by vascular cells and reduce subsequent inflammatory signaling, which prevents macrophage adhesion and infiltration. Moreover, these agents suppress the oxLDL-induced transformation of macrophages into foam cells by either inhibiting oxLDL entrance, or by facilitating its efflux. Thus, the anti-inflammatory, anti-oxidant, and anti-apoptotic properties of antidiabetic agents abrogate changes induced by oxLDL, which can be extremely beneficial in controlling atherosclerosis in diabetic patients.

BackgroundFunctional dyspepsia is the main cause of upper abdominal discomfort affecting 5-10% of the world population. Despite various therapeutic approaches, up to 50% of patients with functional dyspepsia seek alternative treatments. In the present study we evaluated the effect of curcumin supplementation along with famotidine therapy on severity of functional dyspepsia. A total of 75 patients with functional dyspepsia according to Rome III criteria were allocated into intervention (N = 39) or control (N = 36) groups. The intervention group was treated with a combination of 500 mg curcumin and 40 mg famotidine daily for 1 month. The control group received placebo and 40 mg famotidine. Severity of dyspepsia symptoms was determined using the Hong Kong questionnaire at baseline, after the 1 month treatment and after a 1 month follow-up. The presence of H. pylori antigens in the stool samples was also investigated in all subjects. No significant difference was observed between intervention and control groups in biochemical indices, severity of dyspepsia and rate of H. pylori infection. A significant decrease was observed in severity of dyspepsia (p < 0.001) and rate of H. pylori infection (p = 0.004) immediately after the treatment and follow-up in the curcumin intervention group. This study indicated that curcumin therapy could be a favorable supplementation in the symptom management of functional dyspepsia. Moreover, curcumin could help efficient eradication of H. pylori in these patients.

Anti-arrhythmic agents, like amiodarone, interfere at different stages of the ischemic stroke. However, amiodarone was accompanied with immunological pulmonary complications and adverse neurological effects. We hypothesize that magnesium sulfate in combination with amiodarone holds promise for stroke treatment. Thirty-six patients with confirmed diagnosis of ischemic stroke and atrial fibrillation who received bolus amiodarone were randomly assigned to magnesium sulfate every 24 h or similar volume of normal saline (as placebo) for 5 days. Various severity test scores were used to evaluate the symptoms. Routing biochemistry were also measured at days 1 and 5. Treatment with MgSO4 results in a significant reduction in serum levels of NGAL, Hb, T.Bill, IL-6, IL-8, SNSE, S100B, EGF, PAF, CRP and IgG. Also, MgSO4 treatment significantly improved the RASS, Candida, SOFA, NIHSS and APACHE scores. Moreover, reduction of IL-6, IL-8, SNSE, EGF and APACHE score and increase in RASS score were significantly higher in MgSO4 group compared with placebo. Intravenous administration of MgSO4 in amiodarone-treated stroke patients improved the inflammatory, immunological and neurological indicators and reduced disability in ICU-admitted AIS patients, suggesting that this treatment scheme may prevent amiodarone-induced complications in these patients.

Non-small cell lung cancer (NSCLC) is one of the most common types of lung cancer worldwide. It metastasizes rapidly and has a poor prognosis. The first-line treatment for most patients is a combination of chemotherapy and radiation. In many subjects, using targeted treatments alongside chemoradiation has shown a better outcome in terms of progression and quality of life for patients. These targeted treatments include small biological inhibiting molecules and monoclonal antibodies. In this review, we have assessed studies focused upon the treatment of non-small cell lung cancer. Some therapies are approved, such as bevacizumab and atezolizumab, while some are still in clinical trials, such as ficlatuzumab and ipilimumab, and others have been rejected due to inadequate disease control, such as figitumumab.

BACKGROUND: Different approaches have been proved effective for combating the COVID-19 pandemic. Accordingly, in silico drug repurposing strategy, has been highly regarded as an accurate computational tool to achieve fast and reliable results. Considering SARS-CoV-2's structural proteins and their interaction the host's cell-specific receptors, this study investigated a drug repurposing strategy aiming to screen compatible inhibitors of FDA-approved drugs against viral entry receptors (ACE2 and CD147) and integral enzyme of the viral polymerase (RdRp). METHODS: The study screened the FDA-approved drugs against ACE2, CD147, and RDRP by virtual screening and molecular dynamics (MD) simulation. RESULTS: The results of this study indicated that five drugs with ACE2, four drugs with RDRP, and seven drugs with CD147 achieved the most favorable free binding energy (ΔG < -10). This study selected these drugs for MD simulation investigation whose results demonstrated that ledipasvir with ACE2, estradiol benzoate with CD147, and vancomycin with RDRP represented the most favorable ΔG. Also, paritaprevir and vancomycin have good binding energy with both targets (ACE2 and RdRp). CONCLUSIONS: Ledipasvir, estradiol benzoate, and vancomycin and paritaprevir are potentially suitable candidates for further investigation as possible treatments of COVID-19 and novel drug development.
RESUMEN
AIM: We aimed to describe the epidemiological and clinical characteristics of Iranian patients with COVID-19. METHODS: In this single-center and retrospective study, patients with confirmed COVID-19 infections were enrolled. Univariate and multivariate logistic regression methods were used to explore the risk factors associated with outcomes. RESULTS: Of 179 patients with confirmed COVID-19 infection, 12 remained hospitalized at the end of the study and 167 were included in the final analysis. Of these, 153 (91.6%) were discharged and 14 (8.38%) died in hospital. Approximately half (50.9%) of patients suffered from a comorbidity, with diabetes or coronary heart disease being the most common in 20 patients. The most common symptoms on admission were fever, dyspnea, and cough. The mean durations from first symptoms to hospital admission was 8.64 ± 4.14 days, whereas the mean hospitalization time to discharge or death was 5.19 ± 2.42 and 4.35 ± 2.70 days, respectively. There was a significantly higher age in non-survivor patients compared with survivor patients. Multivariate regression showed increasing odds ratio (OR) of in-hospital death associated with respiratory rates >20 breaths/min (OR: 5.14, 95% CI: 1.19-22.15, p = 0.028) and blood urea nitrogen (BUN) >19 mg/dL (OR: 4.54, 95% CI: 1.30-15.85, p = 0.017) on admission. In addition, higher respiratory rate was associated with continuous fever (OR: 4.08, 95% CI: 1.18-14.08, p = 0.026) and other clinical symptoms (OR: 3.52, 95% CI: 1.05-11.87, p = 0.04). CONCLUSION: The potential risk factors including high respiratory rate and BUN levels could help to identify COVID-19 patients with poor prognosis at an early stage in the Iranian population.

BACKGROUND: Colorectal cancer (CRC) is the third and the fourth most common cancer in Iranian men and women, respectively. Curcuminoids are known to exertprotective effects against several kinds of cancers. We aim to assess the effects of curcuminoids on serum pro- and anti-inflammatory cytokines and quality of life in patients with colorectal cancer undergoing chemotherapy. MATERIAL AND METHODS: This study was a double-blind placebo-controlled trial in patients with CRC (stage 3) aged ≥20 years, who had chemotherapy after the surgery and were referred to Baqiyatallah Oncology Clinic. Patients were randomly assigned to the treatment group receiving curcuminoids capsules (500 mg/day) (n = 36), or the control group taking placebo capsules (n = 36) for 8 weeks. Erythrocyte sedimentation rate (ESR) and serum levels of C-reactive protein (CRP) and 12 pro- and anti-inflammatory cytokines including tumor necrosis factor (TNF-α), interleukin-1α (IL-1α), IL-1ß, IL-2, IL-4, IL-6, IL-8, IL-10, monocyte chemoattractant protein (MCP-1), interferon γ (IFN-γ), epidermal growth factor (EGF), and vascular endothelial growth factor (VEGF)] were measured at baseline and at the end of the intervention. The EORTC-QLQ-C30 instrument was used to assess the quality of life before and after the intervention. Statistical analyses were performed using SPSS software. RESULTS: A total of 67 subjects completed the study as three and two subjects were lost to follow-up in the curcuminoid and placebo groups, respectively. A significant change in CRP (p = 0.002) and ESR (p = 0.0001) was observed in patients supplemented with curcuminoids at the end of 8 weeks compared to placebo. Moreover, IL-1α showed a decreasing trend after curcuminoid supplementation compared to placebo (p = 0.077). A significant improvement in functional (p = 0.002) and global quality of life (p = 0.020) scales was observed in the curcuminoid group. CONCLUSIONS: The results showed that curcuminoids supplementation for a period of 8 weeks (500 mg/day) can improve ESR and serum levels of CRP in stage-3 CRC subjects and improve the global quality of life and functional scales compared to placebo.
