Leishmaniasis is considered one of the different neglected tropical diseases by the World Health Organization. Over the past few decades to tackle leishmaniasis, effective and novel drugs have progressed. But few are expensive some other medication shows poor effects and few drugs with long treatment lead to cause resistance. But it is very important to start a better medication against leishmania so researchers came to the front of the utilization of natural products which are considered a better option. Finding active compounds in medicinal plants is another alternative to currently accessible medications. Materials and methods: This study examined and reported the far more potential natural products used to treat disease caused by Leishmania spp. Leishmaniasis, plant metabolites, in vivo, in vitro, and treatment against leishmaniasis have been used as search terms in the Google Scholar, PubMed, and Science Direct databases, and only papers published between 2015 and 2021 have been chosen for further analysis. Results: The use of novel natural compounds with leishmanicidal action as well as the leishmanicidal activity of natural compounds against promastigote, axenic, and intracellular amastigote forms were included in roughly 20 research papers that were reviewed.Conclusion: Due to their capacity to selectively target parasites without harming host cell viability, herbal plants are a possible source of new anti-leishmanial medication. Future leishmaniasis treatments will draw on the isolated compounds as a source, completing those already offered in clinics.

Background: Lung cancer patients have a higher chance of getting infected and showing severe outcomes from coronavirus disease 2019 (COVID-19). This infection influences the respiratory system, albeit other organs are also involved with high risk related to health. The blend of COVID-19 disease and lung cancer predicts a higher mortality rate and more serious clinical results. Objective: This research reports the Systemic Review and Meta-analysis correlation between COVID-19 patients with lung cancer and comprehensive proof with regards to the mortality of these patients. Methods: A systematic review and meta-analysis are planned to evaluate the data from a PubMed systematic search on Lung Cancer Patients reported by COVID-19, as well as an efficient literature review and information research from 2019 to 2021. Results: 22 out of 3639 review and research literature assessments were gathered, and 10951 patients were COVID +ve and suffering from cancer, with 21% of the patients suffering from SCLC and NSCLC, and lung cancer accounting for 6% of the mortality. Conclusion: Lung cancer Patients who are suffering from COVID-19 additionally reflected the seriousness of the illness and higher rates of intensive care unit confirmations and mechanical ventilation. COVID-19 in patients with lung cancer is related to extreme disease and expanded mortality compared with patients with different tumours and everyone. There is conflicting proof of explicit lung cancer therapies' results. Until more conclusive data is available, lung cancer-coordinated therapy should be restarted as soon as possible in mild to moderate cases to avoid decline and cancer-related mortality.

Background: Leishmaniasis is a neglected disease with a global spread that affects both domestic and wild animals in addition to people. Leishmania donovani is the suspected anthroponotic cause of VL in India, where it is an endemic disease. The reservoir hosts play a crucial role in the life cycle of the Leishmania parasite. The complicated connection between the pathogen, vector, and reservoir exhibits geographical and temporal diversity. Human-to-human and, to a lesser extent, human-to-animal transmission is the principal mechanism for the maintenance of anthroponotic diseases. Scope and approach: A deliberate, systematic search was conducted on PubMed, Science Direct, and Google Scholar using keywords such as "Leishmania donovani," "zoonotic visceral leishmaniasis," and "wild animal reservoir for leishmania donovani." 530 potentially significant references were obtained from these 507 were disallowed due to copy avoidance, irrelevant titles, research publications from nations other than India, or modified compositions. The remaining 20 investigations were later rejected because they did not meet the criteria for inclusion. Finally 3 research papers with 867 goats, 161 cattles, 106 chickens, 26 sheep, 3 buffaloes, 406 dogs and 309 rats were reported. Conclusion: According to the review, goats are the epidemic's primary host and possible reservoir in several regions of India. In the endemic regions of the disease, some species of rodents along with the canines appear to be maintaining the L. donovani transmission cycle.
