    Background: Cystic Fibrosis (CF) is a potentially lethal genetic disorder. The most frequent mutation worldwide in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene is designated as the Delta F508 mutation. This mutation was found in only 33% of Pakistani patients studied. Since the common Pakistani mutations remain to be identified, appropriate screening tools are required to identify disease. Sweat chloride determinations remain the gold standard for diagnosing CF. This study was done to emphasize the importance of using the correct tests.Methods: The study was conducted at the Aga Khan University Hospital. The CFTR delta F508 mutation was tested on blood samples from patients suspected with CF. Sweat chloride analysis using pilocarpine iontopharesis was done with a positive value of greater than 60 meq/L.Results: 57 pediatric samples were screened for the delta F508 mutation and were positive in only 10.6% of all patients tested. 12/57 (21%) had a preliminary sweat test. 6/12 (50%) of these patients had an abnormal sweat test and 3/6 patients with an abnormal sweat chloride (50%) had deltaF508 mutations-- 2/6 (33%) were homozygotes and 1 was a compound heterozygote. Since 79% did not have a sweat test, it was difficult to assess whether this subset of patients had cystic fibrosis with a CFTR mutation other than the delta F508 tested or no CF.Conclusion: Sweat chloride analysis is critical to distinguish CF from other causes of severe pulmonary and pancreatic insufficiencies and to define patients requiring further analysis

    Introduction: Instantly after declaring COVID-19 as a pandemic, many conspiracy theories sprouted through word of mouth and social media. Pakistan is vulnerable to such conspiracy narratives and has experienced failures of polio vaccination programs due to such claims. Recently, two well-known political figures raised voice against COVID-19 vaccines in Pakistan, stating that COVID-19 is a grand illusion by non-Muslims and a great agenda against Muslim countries. This theory is much discussed in the local community, supporting COVID-19 vaccine hesitancy. The current crises created by the COVID-19 pandemic is impacting all dimensions of life. Vaccines have been developed to fight the pandemic and prevent the corona virus. Misperceptions about vaccines persist despite the evidence of vaccine safety. The study aims to identify the misconceptions of the general public of Malikpur community towards COVID-19 vaccine hesitancy and also different conspiracy theories, acceptance, and preference for the COVID-19 vaccine. This study is conducted in Malikpur a rural Community Lahore, Pakistan. Methods: A cross sectional study was carried out through an adaptive questionnaire on a representative random sample of 98 resident of above 18 years old from Malikpur community, Lahore Pakistan. The SPSS software was utilized for statistical data analysis. COVID-19 vaccine hesitancy. Conclusion: This study revealed the existence of conspiracy beliefs regarding the COVID-19 vaccine spread by the social media and word of mouth in Malikpur Community Lahore, Pakistan. These beliefs are posing a major threat to the upcoming immunization program for the control of COVID-19 in Pakistan. We urge healthcare authorities in Pakistan to take measures against such claims before they penetrate to the general community. Anti-vaccine actions could undermine efforts to end the COVID-19 pandemic. We believe that ethical and responsible conduct of mass media, a careful advisory from the Pakistan Electronic Media Regulatory Authority, measures from healthcare authorities, practical maneuvers to increase public awareness and publication of beliefs and opinions from health professionals will help in neutralizing such misleading claims. Because Pakistan is experiencing an overload of disease, with a rise in confirmed cases, immediate action is important to eradicate any possible barriers to a future COVID-19 vaccination program. Results: Many people of Malikpur Community has misconception regarding COVID-19 vaccine that is need to be eradicated as soon as possible otherwise pandemic will not end.

    Cancer is the major challenge across world and the adenocarcinoma of prostate malignancy is the second most prevalent male cancer. Various medicinal plants are used for the treatment and management of various cancers. Matricaria chamomilla L., is one of the extensively used Unani medicament for the treatment of various type of diseases. In the current study we evaluated most of the parameters prescribed for drug standardization using pharmacognostic approaches. The 2,2 Diphenyl-1-picryl hydrazyl (DPPH) method was utilized for the analysis of antioxidant activity in the flower extracts of M. chamomilla. Moreover, we analyzed the antioxidant and cytotoxic activity of M. chamomilla (Gul-e Babuna) through in-vitro method. DPPH (2,2-diphenyl-1-picryl-hydrazl-hydrate) method was utilized for the analysis of antioxidant activity in the flower extracts of M. chamomilla. CFU and wound healing assay were performed to determine the anti-cancer activity. The results demonstrated that various extracts of M. chamomilla fulfilled most of the parameters of drug standardization and contained good antioxidant and anticancer activities. The ethyl acetate showed higher anticancer activity followed by aqueous, hydroalcoholic, petroleum benzene and methanol by CFU method. Also, the wound healing assay demonstrated that ethyl acetate extract has more significant effect followed by methanol and petroleum benzene extract on prostate cancer cell line (C4-2). The current study concluded that the extract of M. chamomilla flowers could act as good source of natural anti-cancer compounds.CCRUM, New Delhi; Science and Engineering Research Board, Department of Science and Technology, Government of India; SERB research grant; Princess Nourah bint Abdulrahman University, Riyadh, Saudi Arabia; South African Medical Research Council (SAMRC) and the National Research Foundation (NRF).https://www.jcancer.orgam2024Medical OncologySDG-03:Good heatlh and well-bein
