Beneficial role of healthy eating Index-2015 score & physical activity on COVID-19 outcomes.

BACKGROUND: Nutritional status and physical activity are essential to maintain a strong immune system. No definite pharmacological strategies for Coronavirus disease 2019 treatment are presently available, so natural enhancement of the immune system is in need. Our goal was to assess the correlation of healthy diet and physical activity on COVID-19 disease outcome. METHODS: This cohort study was conducted on 68 adult patients who contracted mild (38) or moderate [30] cases of COVID-19, recruited via a convenience sampling technique from the outpatient clinic, Kasr Al-Aini Faculty of Medicine, Cairo University Hospital. Patients' Healthy Eating Index (HEI) and degree of physical activity as measured by the Global Physical Activity Questionnaire were evaluated and linked with several inflammatory markers. RESULTS: Most of patients with mild COVID-19 patients (92.1%) were physically active, compared to only 50% of moderate COVID-19. The total Metabolic Equivalent Task-min/week was positively correlated with the lymphocyte percentage. The median total HEI score was significantly higher in the patients with mild COVID-19 than with moderate COVID. Significant positive correlations observed among the lymphocyte count and total HEI-2015. There was approximately a 64% reduction in the probability of acquiring moderate COVID-19 illness for each unit rise in The HEI. CONCLUSION: Healthier nutrition and Physical activity correlated with reduced COVID-19 disease severity. TRIAL REGISTRATION: The study was registered on clinical trial.gov maintained by the US National Library of Medicine (CinicalTrials.gov identifier = NCT04447144; https://clinicaltrials.gov/ ) (25/06/2020).

Synthesis and Evaluation of Thioamide and Bromo Derivatives of 1,3-Diphenylpropane-1,3-dione as 5α-Reductase Inhibitors.

BACKGROUND: 1,3-Diphenylpropane-1,3-dione (1) is an acetylacetone ß-diketone in which both of the methyl groups have been replaced with phenyl groups. It is a component of licorice root extract (Glycyrrhiza glabra) and has anti-mutagenic and anti-cancer properties. It functions as a metabolite, an anti-mutagen, and an anti-neoplastic agent. It is an aromatic ketone and a ß-diketone. 1,3-Diphenylpropane-1,3-dione (1) is primarily used in PVC hard and soft materials, including plates, films, profiles, pipes, and fittings. OBJECTIVES: This research aims to examine the utility of 1,3-diphenylpropane-1,3-dione (1) for the synthesis of a variety of new heterocyclic compounds, such as thioamide, thiazolidine, thiophene-2-carbonitrile, phenylthiazole, thiadiazole-2-carboxylate, 1,3,4-thiadiazole derivatives, 2-bromo-1,3-diphenylpropane-1,3-dione, new substituted benzo[1,4]thiazines, phenylquinoxalines, and imidazo[1,2-b][1,2,4]triazole derivatives of potential biological activity Methods: 1,3-Diphenylpropane-1,3-dione (1) was used as a starting compound for the synthesis of 3-oxo-N,3-diphenyl-2-(phenylcarbonyl)propanethioamide (3) and 2-bromo-1,3-diphenylpropane-1,3-dione (25), which can be used for further preparations. The 5α-reductase inhibitor activity of some of the synthesized compounds was also tested in vivo; the ED50 and LD50 data were established, Results: Using IR, 1H-NMR, mass spectroscopy, and elemental analysis, the structures of all produced compounds were elucidated. Some of these prepared compounds were reported as 5α-reductase inhibitors. CONCLUSION: New heterocyclic compounds can be formed via 1,3-diphenylpropane-1,3-dione (1), and some of these compounds can act as 5α-reductase inhibitors.

MicroRNA-17-92a-1 Host Gene (MIR17HG) Expression Signature and rs4284505 Variant Association with Alopecia Areata: A Case-Control Study.

Accumulating evidence indicates the implication of microRNAs (miRs) in cutaneous and hair follicle immunobiology. We evaluated, for the first time, the miR-17-92a-1 cluster host gene (MIR17HG) expression in peripheral blood of 248 unrelated alopecia areata (AA) patients compared to 244 matched controls using Real-Time qPCR. We also tested its association with different rs4284505A>G genotypes (based on TaqMan allelic discrimination PCR) and the available clinical data. The adjusted odds ratio (OR) and 95% confidence interval (CI) were calculated for each genetic association model. The upregulation of miR-17 was observed in the serum of patients with alopecia compared to controls (p-value = 0.004). The ROC curve showed high diagnostic performance of miR-17 in differentiating between patients and controls (AUC = 0.85, p-value < 0.001). rs4284505*A/G heterozygotes were more susceptible to the disease (OR = 1.57, 95% CI = 1.01−2.45) under the over-dominant model. Interestingly, patients with the rs4284505*G/G genotype had a higher level of miR-17 than those with the A/A and A/G genotypes. The G/G genotype was associated with the severe phenotype (p-value = 0.038). A/G carriers were the youngest (p-value < 0.001), had more frequent scalp infection (p-value = 0.006), exhibited the worst dermatology life quality index score (p-value = 0.037), and responded less to treatment (p-value = 0.033). In conclusion, MIR17HG expression and the rs4284505 variant were significantly associated with AA and could play a role in pathogenesis and phenotype in the Egyptian population. Further multi-center studies in other ethnicities are warranted to replicate the findings.

Early Detection of Cartilage Degradation Among Heavy Manual Workers Using Serum Level of Collagen Type II Metabolite.

BACKGROUND: Work-related musculoskeletal disorders are common health problems in brick manufacturers, where mechanical load leads to degenerative joint diseases. Collagen type II metabolite (C2C) is a small peptide excreted in urine, and its serum concentration can directly reflect articular cartilage decomposition. OBJECTIVE: Early detection of musculoskeletal disorders among brick workers, using serum C2C as a biomarker of cartilage damage. METHODS: This study involved 88 male brick workers in Arab Abu Saed matched to 88 age- and sex-matched controls. Full history taking, pain assessment using the Standardized Nordic Questionnaire, and complete clinical examination were done for both groups. Serum C2C was measured using a competitive immunoassay method. RESULTS: Brick workers involved in the study were of a mean age 30.66 ± 7.90 years and mean work duration 14.80 ± 7.89 years, matched to 88 controls. The majority of the participants (77.3%) were of normal body mass index. An increase in pain/discomfort was found among the exposed group. Serum C2C had an increased mean among the exposed group compared with the control. Pearson correlation between serum C2C level, body mass index, age, and years of employment showed no correlation. CONCLUSIONS: Musculoskeletal disorders are prevalent among brick workers who adopt specific awkward postures, unhealthy working conditions, and nonexistent safety procedures, for prolonged periods. Detection of serum C2C level can be used as a predictive biomarker for the early detection of musculoskeletal disorders among brick workers.

Association of interleukin-36α gene expression in Egyptian patients with systemic lupus erythematosus with organ involvement and disease activity.

Systemic lupus erythematosus (SLE) is a complex systemic autoimmune disease characterized by a wide spectrum of clinical manifestations with varying severity. The dysregulation of cytokines contributes strongly to disease pathogenesis. Recently, it has been shown that the imbalanced antagonist/agonist profile of interleukin (IL)-36 cytokines, might play a role in autoimmune disorders. Our aim is to investigate mRNA expression of Interleukin-36α (IL-36α) in the peripheral blood of Egyptian systemic lupus erythematosus (SLE) patients and its association with disease activity and organs involvement. We assessed the relative expression of IL-36α mRNA by real time polymerase chain reaction and the comparative CT method on the peripheral blood of 49 SLE patients, and 40 healthy controls. Patients were subjected to thorough history and clinical examination, in addition to routine hematological, biochemical, and serological studies. Disease activity was evaluated using the SLE Disease Activity Index (SLEDAI). The relative expression of IL-36α mRNA was significantly higher in SLE patients compared to healthy controls (4.3±2.9 vs 1, respectively, P<0.0001). Fold change of IL-36α expression was significantly increased in patients with moderate and high disease activity (SLEDAI>5) than patients with mild disease activity (SLEDAI≤5) (4.3±1.2 vs 2.7±2.0, respectively, P=0.006) and positively correlated with SLEDAI (r=0.505, P=0.001). Regarding major organ involvement, the mean±SD expression of IL-36α in patients with arthritis and mucocutaneous involvement was significantly higher compared to those without organ involvement (4.2±1.5 vs 2.8±1.8, P=0.039 and 4.1±1.4 vs 2.8±2.1, P=0.041, respectively). In conclusion, the IL-36α is significantly more expressed in SLE patients compared to healthy controls and correlated with SLE disease activity and arthritis. IL-36α expression could be a useful biomarker for SLE disease activity in Egyptian patients with SLE.
