The Effect of Tang Forte (Royal Jelly) Capsule on Hypoglycemia and Clinical Course in COVID-19 Patients Under Corticosteroid Therapy.

Corticosteroids improve the complications of Covid-19 but may cause some side effects such as hyperglycemia. Royal jelly is one of the bee products that exert anti-inflammatory, insulin-like, and hypoglycemic activities. The present study was conducted to investigate the effect of royal jelly capsules on blood sugar and the clinical course of Covid-19 in the patients receiving corticosteroid therapy. In this clinical trial, 72 Covid-19 patients with positive reverse transcription polymerase chain reaction (RT-PCR) test and pulmonary involvement hospitalized in Shahrekord Hajar Hospital were enrolled and randomized into two groups: treatment (receiving corticosteroids and Royal Jelly 1000 mg capsules daily for 7 days) and placebo (given corticosteroids and placebo). Laboratory tests, blood sugar, and clinical courses were determined and compared. Data was analyzed using SPSS version 16. On day 7 after the onset of the intervention, the dosage and frequency of insulin, FBS level, and required corticosteroid showed a decrease in both groups but the inter-group difference was not significant (P > .05). As well, the Spo2 level indicated a non-significant increase and hospital stay length indicated a non-significant decrease in the intervention group (P > .05). Among the symptoms, only headache, cough, and dyspnea indicated an improvement in the intervention group (P < .05). Overall, the results indicated the short-term consumption of royal jelly could not significantly improve blood sugar and the clinical course of Covid-19; however, it could significantly improve headache, cough, and dyspnea in the patients.

Saffron and Its Major Ingredients' Effect on Colon Cancer Cells with Mismatch Repair Deficiency and Microsatellite Instability.

BACKGROUND: Colorectal cancer (CRC) is one of the most common cancers worldwide. One of its subtypes is associated with defective mismatch repair (dMMR) genes. Saffron has many potentially protective roles against colon malignancy. However, these roles in the context of dMMR tumors have not been explored. In this study, we aimed to investigate the effects of saffron and its constituents in CRC cell lines with dMMR. METHODS: Saffron crude extracts and specific compounds (safranal and crocin) were used in the human colorectal cancer cell lines HCT116, HCT116+3 (inserted MLH1), HCT116+5 (inserted MSH3), and HCT116+3+5 (inserted MLH1 and MSH3). CDC25b, p-H2AX, TPDP1, and GAPDH were analyzed by Western blot. Proliferation and cytotoxicity were analyzed by MTT. The scratch wound assay was also performed. RESULTS: Saffron crude extracts restricted (up to 70%) the proliferation in colon cells with deficient MMR (HCT116) compared to proficient MMR. The wound healing assay indicates that deficient MMR cells are doing better (up to 90%) than proficient MMR cells when treated with saffron. CDC25b and TDP1 downregulated (up to 20-fold) in proficient MMR cells compared to deficient MMR cells, while p.H2AX was significantly upregulated in both cell types, particularly at >10 mg/mL saffron in a concentration-dependent manner. The reduction in cellular proliferation was accompanied with upregulation of caspase 3 and 7. The major active saffron compounds, safranal and crocin reproduced most of the saffron crude extracts' effects. CONCLUSIONS: Saffron's anti-proliferative effect is significant in cells with deficient MMR. This novel effect may have therapeutic implications and benefits for MSI CRC patients who are generally not recommended for the 5-fluorouracil-based treatment.

Clinical features, demographics, laboratory and imaging data of patients hospitalized with coronavirus disease 2019 (COVID-19) in Iran.

INTRODUCTION: The Coronavirus disease 2019 (COVID-19) outbreak is an increasing major global public health threat. Mortality rate varies across countries, therefore conducting studies on this disease in different countries is necessary, and will improve disease management worldwide. OBJECTIVE: This study aimed to investigate the COVID-19 disease course characteristics in Iran. METHODS: This is a retrospective study of 108 patients with confirmed COVID-19 from Feb 20 to June 20, 2020, at one Hospital in Iran. In summary, we obtained demographic data, clinical, laboratory, and chest CT findings of patients. The statistical analysis evaluated patients in two groups: recovered or died. RESULT: In brief, cough (70/108, 64.8%) and fever (69/108, 63.9%) were the most common symptoms. CT scan findings of patients with COVID-19 showed that bilateral lung involvement was more common in deceased patients than recovered ones (20/26, 76.9% vs. 30/70, 42.8%, p = 0.026). Laboratory findings of routine blood tests including Erythrocyte sedimentation rate (ESR), Fasting Blood Sugar (FBS), White Blood Cell (WBC), the number of platelets (PLTs) showed a significant difference between the two groups (p <0.05). There were no significant differences in age and gender between the two groups. CONCLUSION: In this study, we described the features of deceased and recovered patients with COVID-19. Our findings suggest that levels of FBS, ESR, WBC, and PLTs, also patterns of lung involvement, existence of underlying disease, respiratory rate, and oxygen saturation can be predictors of mortality risk. Further studies are proposed to investigate these characteristics in different populations.

Saffron Crudes and Compounds Restrict MACC1-Dependent Cell Proliferation and Migration of Colorectal Cancer Cells.

The high mortality rate of colorectal cancer (CRC) patients is directly associated with metastatic dissemination. However, therapeutic options specifically for metastasis are still limited. We previously identified Metastasis-Associated in Colon Cancer 1 (MACC1) as a major causal metastasis-inducing gene. Numerous studies confirmed its value as a biomarker for metastasis risk. We investigated the inhibitory impact of saffron on MACC1-induced cancer cell growth and motility. Saffron crudes restricted the proliferation and migration of MACC1-expressing CRC cells in a concentration- and MACC1-dependent manner. Saffron delays cell cycle progression at G2/M-phase and does not induce apoptosis. Rescue experiments showed that these effects are reversible. Analysis of active saffron compounds elucidated that crocin was the main compound that reproduced total saffron crudes effects. We showed the interaction of MACC1 with the cancer stem cell (CSC) marker DCLK1, which contributes to metastasis formation in different tumor entities. Saffron extracts reduced DCLK1 with crocin being responsible for this reduction. Saffron's anti-proliferative and anti-migratory effects in MACC1-expressing cells are mediated by crocin through DCLK1 down-regulation. This research is the first identification of saffron-based compounds restricting cancer cell proliferation and motility progression via the novel target MACC1.

Elevated Risk for Sessile Serrated Polyps in African Americans with Endometrial Polyps.

BACKGROUND: Colorectal and endometrial lesions increase with age. It is not known if these two precursor lesions in sporadic cases associate with each other. AIM: To determine the association between colorectal polyps and endometrial polyps (EP) in African Americans. METHODS: We reviewed records of patients referred to gynecology clinics and had colonoscopy at Howard University Hospital from January 2004 to December 2015. We defined cases as all patients who had EP and underwent colonoscopy. For controls, we used EP-free patients who underwent colonoscopy. Logistic regression analysis was used to assess the association between colon polyps and EP. RESULTS: The median age was 60 years in 118 Cases and 57 years in 664 Controls. The overall colorectal polyps prevalence in the two groups was not statistically different (54% in controls vs. 52% in cases, P = 0.60). Sessile serrated adenoma/polyps (SSPs) were more frequent in cases (8% vs. 2% in controls, P = 0.003). Sigmoid and rectal locations were more prevalent in controls than cases. In multivariate analysis and after adjusting for age, diabetes mellitus (DM), and BMI, SSPs were associated with EP occurrence with an odds ratio of 4.6 (CI 1.2-16.7, P = 0.022). CONCLUSION: Colorectal polyp prevalence was similar in EP patients compared to EP-free controls. However, we observed a significant association between higher-risk SSPs in patients with EP. The prevalence of smoking and DM was higher in these patients. Females with EP might benefit from a screening for colonic lesions in an age-independent manner.

Can the rate and location of sessile serrated polyps be part of colorectal Cancer disparity in African Americans?

BACKGROUND: Up to 30% of colorectal cancers develop through the serrated pathway. African Americans (AAs) suffer a disproportionate burden of colorectal cancer. The aim of this study was to evaluate clinicopathological features of AA patients diagnosed with sessile serrated polyps (SSPs). METHODS: We conducted a retrospective study of all colonoscopies (n = 12,085) performed at Howard University Hospital, from January 1st, 2010 to December 31st, 2015, of which 83% were in AA patients, (n = 10,027). Among AAs, pathology reports confirmed 4070 patients with polyps including 252 with SSPs. Demographic and clinical variables (i.e. sex, age, BMI, anatomic location, clinical symptoms, polyp size, and clinical indications were collected at colonoscopy. RESULTS: In the AA population, the median age was 56 with interquartile range (IQR) of 51 to 62 years, 54% were female, and 48% had a BMI > 30. The most common reason for colonoscopy was screening (53%), whereas the prevalent reasons for diagnostic colonoscopies were changes in bowel habits (18%) and gastrointestinal bleeding (17%). The total number of SSPs among the 252 AA (diagnosed with SSPs) was 338. Of these, 9% (n = 29/338) had some degree of cytological dysplasia, primarily in the ascending colon (n = 6/42, 14%), Transverse colon (n = 2/16, 13%) and rectosigmoid (n = 19/233, 8%). About 24% of patients had more than 2 polyps. Most patients (76%) had distal SSPs (rectal and rectosigmoid), in comparison to 14% of proximal polyps and 10% of bilateral locations. Median SSA/P size for all locations was 0.6 cm. CONCLUSION: The prevalence of SSPs accounts for 6% of all polyps in AA patients and was diagnosed in 2.5% of all colonoscopies (n = 252/10,027), which is higher than Caucasians in the US. SSPs were predominantly located in the left side, as compared to published literature showing the predominance in the right side of the colon. Screening of CRC will have the chance to detect high risk SSA/P in this population.

Saffron: The Golden Spice with Therapeutic Properties on Digestive Diseases.

Saffron is a natural compound that has been used for centuries in many parts of the world as a food colorant and additive. It was shown to have the ability to mitigate various disorders through its known anti-inflammatory and anti-oxidant properties. Several studies have shown the effectiveness of saffron in the treatment of various chronic diseases like inflammatory bowel diseases, Alzheimer's, rheumatoid arthritis as well as common malignancies of the colon, stomach, lung, breast, and skin. Modern day drugs generally have unwanted side effects, which led to the current trend to use naturally occurring products with therapeutic properties. In the present review, the objective is to systematically analyze the wealth of information regarding the potential mechanisms of action and the medical use of saffron, the "golden spice", especially in digestive diseases. We summarized saffron influence on microbiome, molecular pathways, and inflammation in gastric, colon, liver cancers, and associated inflammations.

Adiponectin, Leptin, IGF-1, and Tumor Necrosis Factor Alpha As Potential Serum Biomarkers for Non-Invasive Diagnosis of Colorectal Adenoma in African Americans.

The potential role of adiponectin, leptin, IGF-1, and tumor necrosis factor alpha (TNF-α) as biomarkers in colorectal adenoma is not clear. Therefore, we aimed to investigate the blood serum levels of these biomarkers in colorectal adenoma. The case-control study consisted of serum from 180 African American patients with colon adenoma (cases) and 198 healthy African Americans (controls) at Howard University Hospital. We used ELISA for adiponectin, leptin, IGF-1, and TNF-α detection and quantification. Statistical analysis was performed by t-test and multivariate logistic regression. The respective differences in median leptin, adiponectin, IGF-1, and TNF-α levels between control and case groups (13.9 vs. 16.4), (11.3 vs. 46.0), (4.5 vs. 12.9), and (71.4 vs. 130.8) were statistically significant (P < 0.05). In a multivariate model, the odds ratio for adiponectin, TNF-α, and IGF-1 were 2.0 (95% CI = 1.6-2.5; P < 0.001), 1.5 (95% CI = 1.5(1.1-2.0); P = 0.004), and 1.6 (95% CI = 1.3-2.0; P < 0.001), respectively. There was a positive correlation between serum adiponectin and IGF-1 concentrations with age (r = 0.17, P < 0.001 and r = 0.13, P = 0.009), TNF-α, IGF-1, and leptin concentration with body mass index (BMI) (r = 0.44, P < 0.001; r = 0.11, P = 0.03; and r = 0.48, P < 0.001), respectively. Also, there was a negative correlation between adiponectin and leptin concentrations with BMI (r = -0.40, P < 0.001), respectively. These data support the hypothesis that adiponectin, IGF-1, and TNF-α high levels correlate with higher risk of colon adenoma and can thus be used for colorectal adenomas risk assessment.

Effect of Anti-Cyclic Citrullinated Peptide and HLA-DRB1 Subtypes on Clinical Disease Activity Index in Rheumatoid Arthritis Patients.

INTRODUCTION: Rheumatoid arthritis (RA) is a crippling disease with a global prevalence of approximately 0.5%-1% in adults. Genetic, environmental and immunologic factors contribute importantly to pathogenesis of RA. American College of Rheumatology (ACR) assists in early diagnosis of the disease. AIM: The aim of this study was to investigate the effects of HLA-DRB1 gene and anti-Cyclic Citrullinated Peptide (CCP) antibody on Clinical Disease Activity Index (CDAI) and to determine the frequency of HLA-DRB1 alleles in the patients with RA. MATERIALS AND METHODS: In this descriptive-analytical study, 64 patients with RA referring rheumatology clinic of Hajar Hospital, Shahr-e-Kord, Iran were enrolled based on ACR criteria (1987) by convenience sampling. All patients were examined to assess primary CDAI and referred to laboratory for serologic tests [Rheumatoid Factor (RF) and anti-CCP]. After the patients' DNA was extracted, HLA-DRB1 was determined per single specific primer-polymerase chain reaction by inno-train kits. The patients were re-examined six months later. RESULTS: The most prevalent type of HLA-DRB1 in the studied patients was 04. In patients with HLA-DRB1 (04), HLA-DRB1 (01), and HLA-DRB1 (15), CDAI decreased pronouncedly after six months, but in other patients it did not (p<0.05). Of the patients, 81.3% had high titers of anti-CCP, but no association between anti-CCP and CDAI was found. CONCLUSION: RA could be a multifactorial disease. The patients with HLA-DRB1 (04), HLA-DRB1 (01) and HLA-DRB1 (15) showed a good response to routine treatments. The patients with HLA-DRB1 (04) are likely to have no decrease in secondary CDAI. High titers of anti-CCP in patients may indicate the severity of RA in the studied region and perhaps environmental, genetic and unknown or idiopathic factors are aetiologically crucial.

Association of Deficiency of Coagulation Factors (Prs, Prc, ATIII) and FVL Positivity with Preeclampsia and/or Eclampsia in Pregnant Women.

BACKGROUND: Thrombophilia is a pathological state of increased blood coagulability. It causes problems during pregnancy including preeclampsia, stillbirth, repeated abortions, and detached pair. Out of the most prevalent factors causing inherited thrombophilia, protein S (Prs), protein C (Prc), and antithrombin III (ATIII) deficiency, and Factor V Leiden (FVL) mutation could be mentioned. This study aimed to investigate association of these parameters with preeclampsia. METHODS: In this case-control study, 142 pregnant women with preeclampsia referred to Obstetric Clinic of Hajar Hospital, southwest of Iran, were assigned to the case group after clinical laboratory tests and according to specialist point of view and 142 pregnant women with normal blood pressure were assigned to the control group. After obtaining consent and completing relevant questionnaire, a 4-cc blood sample was taken from the patients. Coagulation factors and FVL rate were measured and after 6 months patients were followed- up. Data analysis was done by SPSS software using t-test. RESULTS: In view of deficiency of Prs, Prc, and ATIII, no statistically significant association was observed between case and control groups (P>0.05). Statistical t-test indicated that the rate of FVL deficiency in pregnant patients with preeclampsia was significantly different from that in the control group (p=0.03). In addition, the body mass index of case group was significantly higher than that of control group prior to pregnancy (P=0.001). In case group, preeclampsia history contributed to development of current preeclampsia in contrast to control group (p<0.001). The patients of case group were followed up after 6 months in view of blood pressure and all had a normal mean blood pressure at the completion of the study. CONCLUSION: Measurement of FVL deficiency could help to decrease the unpleasant complications of vascular disorders during pregnancy. But, screening test for pre-eclampsia does not seem necessary to determine the deficiency of coagulation factors, Prs, Prc, and ATIII.

Effect of self - care education on quality of life in patients with primary hypertension: comparing lecture and educational package.

BACKGROUND: Hypertension is a dangerous risk factor for public health. It profoundly affects the patients' quality of life. However, there is lack of agreement on the best method for self-care management in patients with hypertension. OBJECTIVES: This study was conducted to compare the effect of lecture and educational pamphlets on quality of life (QOL) in patients with primary hypertension. PATIENTS AND METHODS: A quasi-experimental study was performed on 90 patients with chronic primary hypertension referred to two outpatient clinics in Kashan city. Patients were randomly divided into three groups including lecture group, educational package group, and control group. The participants' quality of life was measured using the SF-36 questionnaire at the beginning of the study, and two months later. Data was analyzed using ANOVA and Chi-Square tests. RESULTS: No significant differences were observed between the three groups for demographics characteristics and QOL before the intervention except for marital status. Mean scores of QOL dimensions of the intervention groups were increased at the end of the study, except for the dimension of bodily pain. Tukey post-Hoc test showed that except for general health, the two intervention groups were not significantly different in other dimensions, and significant differences were observed between the control group and the two intervention groups (P < 0.05). At start and the end of the study, the mean differences in the general health dimension in three groups were 2.25 ± 0.1, 0.07 ± 0.01, and -1.70 ± 0.01 respectively. There were significant differences among groups (P = 0.04). CONCLUSIONS: Lecture and educational package can both improve some dimensions of the QOL in patients with hypertension. However, as pamphlets are cheap and easy to use, this method may be used as an effective method for self-care education in health care settings in Iran, where the system is faced with nursing shortage.
