Introduction: Hepatitis B virus (HBV) infection is a major global health issues and one of the most dangerous viral infections with a high mortality rate. Newborns and infant vaccination against chronic HBV infection are crucial for preventing mother-to-child transmission (MTCT). This study aimed to conduct a meta-analysis to investigate the factors affecting long-term protection against Hepatitis B Immunization in infancy. Material and Methods: Our literature searches are from PubMed, Science Direct, Web of Science, and ProQuest publications between January 2000 and December 2021. The included literature assessed the risk of bias using the Newcastle Ottawa Quality Assessment Scale. We identify Hepatitis B surface antibodies (anti-HBs) >= 10 mIU/mL as being protective against HBV infection. The results are combined with a random effect or fixed effect model. Results: Eighteen eligible observational studies with a total of 16,642 participants were included. Analysis of factors affecting long-term protection status by assessing anti-HBs titers showed significant results on several factors, including gestational age for anti-HBs titers (OR 2.5; 95\% CI 1.62-3.85; p\<0.0001), weight for age to anti-HBs titers (OR 1.36; 95\% CI 1.06-1.75; p=0.02), length for age to anti-HBs titers (OR 0.01; 95\% CI 0.01-0.02; p\<0.00001), and immunization status based on the number of vaccine doses (4 doses vs 3 doses) to anti-HBs titers (p\<0.00001). Conclusions: Anti-HBs titers of hepatitis B immunization were significantly affected by gestational age, weight for age, length for age, and vaccine doses. Parents of newborns must be informed about basic immunization and provide adequate nutritional intake to the mother and babies to prevent HBV infection.

Background: Multinucleated giant cells were first described by Langhans(MGCs), these MGCs have a role in innate immunity that includes extracellular matrix remodeling associated with granuloma formation; another function of them is to participate in the removal of cellular debris in apoptosis during certain infections. Objective: Generate multinucleated giant cells due to Leishmania (V.) braziliensis infection. Methods: For infection macrophage/parasite ratio of 1 to 10 using the RAW 264.7-line (5 x105/mL) and Leishmania (V.) braziliensis metacyclic promastigotes (50 x105/mL) was a strain maintained in culture Schneider liquid medium, supplemented with 20\% fetal bovine serum and 10 000 U/10 mg/mL penicillin streptomycin at pH 7 and 25 {\textdegree}C in the laboratory. Incubation was continued for 4 days, and microscopic observation at 1000X was performed at 24 hours and 96 hours, respectively. Results: In our study an MGC conversion was observed at 96 hours (50\% {\textpm} 28.2). Conclusions: In vitro MGC model could be used to study the physiopathology of MGC generation by Leishmania (V.) braziliensis infection.

Adequate nutrition intake is one of main factors to strengthen immunity. Traditional and cultural practices of food consumption involve use of several spices in limited quantities as part of food. Spices have offered versatile biological effects due to presence of valuable biochemicals. The aim of the present paper is to review published scientific evidence on potential role of spices in offering innate and adaptive immunity to human body. It has been demonstrated that, turmeric, one of the widely used spices, acts as an anti-viral agent through inhibition of viral entry into cells, suppression of viral replication and modulation of cytokines. A field study revealed that nations with higher consumption of spices have shown lesser COVID-19 cases and higher recovery rates. Further, spices also have shown to possess antioxidant activity superior or equivalent to ascorbic acid and are known to regulate inflammation processes. Evidence generated from the published literature is compelling to arrive at a conclusion that consumption of spices might improve immunity there by offering protection against various diseases including COVID-19. It is also noted that there are lesser number of human clinical trials in this area which warrants immediate attention to provide scientific evidence to immunity offered by spices.
