Infectious disease (ID) is one of the top-most serious threats to human health globally, further aggravated by antimicrobial resistance and lack of novel immunization options. Andrographis paniculata (Burm. f.) Wall. ex Nees and its metabolites have been long used to treat IDs. Andrographolide, derived from A. paniculata, can inhibit invasive microbes virulence factors and regulate the host immunity. Controlled clinical trials revealed that A. paniculata treatment is safe and efficacious for acute respiratory tract infections like common cold and sinusitis. Hence, A. paniculata, mainly andrographolide, could be considered as an excellent candidate for antimicrobial drug development. Considering the importance, medicinal values, and significant role as antimicrobial agents, this study critically evaluated the antimicrobial therapeutic potency of A. paniculata and its metabolites, focusing on the mechanism of action in inhibiting invasive microbes and biofilm formation. A critical evaluation of the secondary metabolites with the aim of identifying pure compounds that possess antimicrobial functions has further added significant values to this study. Notwithstanding that A. paniculata is a promising source of antimicrobial agents and safe treatment for IDs, further empirical research is warranted.

Thalassemia is one of the most common life-threatening yet preventable congenital hemoglobin disorders especially in South Asian regions like Bangladesh. It has become a rising public health concern for Bangladesh as 6–12% of the population are carriers and many of them are unaware of it. The purpose of the study is to inspect the knowledge and attitude towards thalassemia among the general people of Bangladesh. A cross-sectional survey was conducted in eight administrative regions of Bangladesh between January and October of 2020. A structured questionnaire was designed to collect information about thalassemia and socio-demographic characteristics. Multivariate logistic regression models were used to identify factors associated with knowledge of thalassemia. A p-value <0.05 was considered significant. Of the 1,248 participants, only 47.4% had heard of thalassemia. Half of the participants who heard about the disease had no idea that thalassemia was not a transfusion transmitted disease. Only 49.8% of participant correctly identified consanguineous marriages as an important risk factor. Majority of them knew that marriage between two carriers can lead to a child with thalassemia major. About 72.5% knew that blood tests are a diagnosis method to determine thalassemia. Among the socio-demographic variables, the level of education of the respondents was identified as an independent predictor for knowledge (p<0.05) on thalassemia. For example, graduate (aOR: 24.88; 95% CI: 6.238–99.232) or post-graduate (aOR: 33.18; 95% CI: 7.864–140.001) participants were more aware of thalassemia than non-graduates. However, about 68.2% of the participants showed a positive attitude towards premarital screening of themselves or their family members and 85.3% were willing to donate blood to thalassemia patients. The study shows that there is a need to disseminate the information on thalassemia since the knowledge gap is huge among people. These findings will strengthen the implementation of thalassemia major awareness through educational programs, health counseling, premarital screening and campaigning.

Background: Thalassemia is one of the most common life-threatening yet preventable congenital hemoglobin disorders especially in South Asian regions like Bangladesh. It has become a rising public health concern for Bangladesh as 6-12% of the population are carriers and many of them are unaware of it. The purpose of the study is to inspect the knowledge and attitude towards thalassemia among the general people of Bangladesh. Methods: A cross-sectional survey was conducted in eight administrative regions of Bangladesh between January and October of 2020. A self-administrative close-ended questionnaire was designed to collect information about thalassemia and socio-demographic characteristics. Pearson’s chi-square (χ2) test and One-way ANOVA were performed to assess the association between the demographic variables with knowledge and practice regarding thalassemia. A p-value <0.05 was considered significant.Results: Of the 1623 participants, only 44.7% (726/1623) had heard of thalassemia. The mean knowledge of thalassemia was scored 4.75 ± 2.05 out of a total possible score of 10. Half of the participants had no idea that thalassemia was not a transfusion transmitted disease. About 73.1% knew that blood tests are a diagnosis process to determine thalassemia. The urban residing participants had the highest (5.10 ± 1.99) and participants with primary education had the lowest (3.38 ± 1.37) mean score of knowledge. Participants' knowledge score varied significantly by marital status, living pace, literacy and occupation (p< 0.05). However, about 68.2% and 85.5% of the participants showed a positive attitude towards premarital screening of themselves or their family members and donating blood to thalassemia patients, respectively. Conclusion: The study shows that there is a need to disseminate the information on thalassemia since the knowledge gap is huge among people. These findings will assist the implementation of significant steps such as educational programs, health counseling, premarital screening, campaigning, etc. to increase the awareness of thalassemia.

Justicia gendarussa is a well-known medicinal plant from ancient times that has been using to treat a variety of ailments. The main objectives of the current study were to assess the phytochemicals, molecular identification of the plant, and determination of MIC, as well as antimicrobial and anti-inflammatory activities of various types of plant extracts (aqueous, ethanolic, methanolic, diethyl-ether, dichloromethane, and ethyl-acetate extracts) of J. gendarussa (leaves) against 11 human pathogens, including bacteria and fungi. In the present study, J. gendarussa was identified as a medicinal plant based on ITS gene amplification by PCR. The screening of the presence of important phytochemicals that carry high significance from a therapeutic standpoint was also carried out. The antimicrobial activity was assessed by following the disc diffusion and broth dilution procedures. The highest antimicrobial activity was observed against S. aureus (16 mm), S. flexneri (15 mm), and C. albicans (15 mm) compared with gentamicin (10 μg/disc) and fluconazole (25 μg/disc). Besides this, methanolic extract showed the highest anti-inflammatory activity (76% membrane protection). The MIC values (8–2048 μg/ml) of aqueous extract were observed against both types of bacteria and fungi, with the highest MIC value recorded at (2048 μg/ml) for S. flexneri. This study is the primary investigation in Bangladesh where molecular identification of this medicinal plant was carried out and the anti-inflammatory activity of this plant was evaluated by the HRBC membrane stabilization method. In conclusion, our findings suggest that this plant may be useful in research and development for discovering a broad spectrum of modern herbal medicines.
