Immune hyperactivation has been linked to various vaccines. We present a potential association of newonset systemic lupus erythematosus (SLE) post-COVID-19 immunization. The patient is a 54-year-old male admitted for evaluation of flu-like symptoms two weeks after receiving the second dose of the COVID-19 vaccine. Physical examination revealed high-grade fever, diffuse bilateral non-tender cervical lymphadenopathy, and erythematous maculopapular palpable purpuric lesions on bilateral feet. Laboratory evaluation showed a significant hypocomplementemia (C3 < 11 mg/dL, C4 < 3 mg/dL, and CH50 < 10 U/mL), high titer antinuclear antibody, anti-dsDNA antibodies, anti-Sjogren's syndrome-related antigen A antibodies, anti-Sjogren's syndrome-related antigen B antibodies, anti-Smith antibodies, antiribonucleoprotein antibodies, anti-histone antibodies with a negative malignancy, and infection workup. The patient was treated with a high dose of steroids with a positive response. This case highlights the possibility of SLE, a rare adverse event following COVID-19 vaccination.

In recent work, the Jeffrey liquid with uniform dust particles in a symmetric channel is studied. Moving sinusoidal wave is executed on the walls of the channel, which generates peristaltic transport in the fluid. The governing equations for fluid and dust particles have been formulated using stream function. Perturbation method is used to get analytical solution of the problem by using small wave number. Graphical analysis has been carried out for stream function and velocity of fluid and dust particles. Effects of different parameters such as curvature k, relaxation time [Formula: see text], wave number [Formula: see text] and retardation time [Formula: see text] are debated through graphs for both dust particles and fluid. The noteworthy outcomes are fluid velocity, pressure gradient in the region [Formula: see text] and bolus size increases by increasing [Formula: see text]

Iron supplementation and fortification are the well-known approaches to treat iron deficiency anemia (IDA) in women of reproductive age. The objective of the current randomized controlled trial (RCT) was to evaluate the cumulative effects of prebiotics and iron fortification among women of reproductive age. For this purpose, a total of 75 iron deficient women of childbearing age were recruited and randomly divided into 5 groups (4 treatment groups and 1 control group). Four different types of fortified wheat flour were prepared using two iron fortificants (NaFeEDTA and FeSO4) and two prebiotics [inulin and galacto oligosaccharides (GOS)], while control group was treated with iron fortified flour without any prebiotics. Blood samples were collected from overnight fasted women on monthly basis up to 90 days. Hematological indices such as Hemoglobin (Hb), Hematocrit, Red Blood Cell (RBC) Count and Mean Corpuscular Volume (MCV), as well as iron biomarkers including serum iron, ferritin, transferrin, and Total Iron Binding Capacity (TIBC) were evaluated for analyses. The results showed a considerable positive improvement in all iron biomarkers as well as hematological indices among the treatment groups (P-value &lt; 0.05), as compared to the control group. A maximum Hb (11.86 ± 0.24 mg/dL) and hematocrit value (35.06 ± 1.32%), was reported in group G3 which was treated with fortified wheat flour at a dose of 963 mg/kg GOS + 15 ppm FeSO4. On the other hand, highest mean values for RBC Count (4.73 ± 0.41 mil/mm3), MCV (81.41 ± 3.21 fL), serum iron (75.62 ± 2.79 μg/dL), serum transferrin (16.82 ± 0.30 mg/dL), and TIBC (403.68 ± 7.27 μg/dL) were observed in G4 group receiving the fortified wheat flour at a dose of 963 mg/kg GOS + 30 ppm FeSO4 level. The study concluded that prebiotic fortification along with iron salts helps to enhance iron absorption among iron deficiency anemic women of reproductive age.
