RESUMEN
Background: Childhood trauma is a major threat to the welfare and prosperity of any society. Young adult population is vulnerable due to increasing adverse childhood experiences and the likelihood of serious implications in educational performance and mental health. This survey was aimed to observe the proportion of various types of childhood traumas and their association with different socio-demographic characteristics among young university students of Karachi, Pakistan. Methods: This cross-sectional study was conducted among 300 young university students, during August-December 2023. Initially, cluster sampling was done deemed to the epidemiological survey. Afterwards, from the selected clusters, students from different universities were approached using non-probability convenient sampling technique. Self-reported data were collected through a questionnaire comprising of socio-demographic characteristics along with the types of traumas experienced during their childhood. SPSS Version 26.0 was used to analyse data. Results: Of the 300 university students with a mean age of 22.14±2 years, 55.3% were females. Overall, 63.6% of the participants experienced trauma before 18 years age. The most common trauma types reported were physical/verbal abuse (81%), unlawful touch/sexual abuse (45%), parents separated/divorced (31%) abandoned by parents (20%), lived with an alcoholic/drug addict (18%) or with a mentally ill adult (14%). There were no statistically significant findings between childhood trauma experience and socio-demographic traits. Conclusions: Various profiles of childhood trauma were found prevalent in young university level individuals. Current research does suggest a way forward to prevent this public health issue that can have detrimental consequences on an individual’s mental and physical health and stress reactivity.
RESUMEN
Abstract The present study was aimed to manifest the antibacterial and antifungal activity of methanolic extracts of Salix alba L. against seven Gram-positive and Gram-negative bacterial pathogens e.g. Streptococcus pyogenes, Staphylococcus aureus (1), S. aureus (2), Shigella sonnei, Escherichia coli (1), E. coli (2) and Neisseria gonorrhoeae and three fungal isolates from the air such as Aspergillus terreus, A. ornatus, and Rhizopus stolonifer. Two different serotypes of S. aureus and E. coli were used. The agar well-diffusion method results showed the dose-dependent response of plant extracts against bacterial and fungal strains while some organisms were found resistant e.g. E. coli (1), S. sonnei, A. terreus and R. stolonifer. The highest antibacterial activity was recorded at 17.000±1.732 mm from 100 mg/mL of leaves methanolic extracts against S. pyogenes while the activity of most of the pathogens decreased after 24 h of incubation. The highest antifungal activity was reported at 11.833±1.0 mm against A. ornatus at 50 mg/mL after 48 h of the incubation period. These experimental findings endorse the use of S. alba in ethnopharmacological formulations and suggest the use of methanolic extracts of the said plant to develop drugs to control the proliferation of resistant disease causing pathogenic microbes.
Resumo O presente estudo teve como objetivo manifestar a atividade antibacteriana e antifúngica de extratos metanólicos de Salix alba L. contra sete patógenos bacterianos Gram-positivos e Gram-negativos. Streptococcus pyogenes, Staphylococcus aureus (1), S. aureus (2), Shigella sonnei, Escherichia coli (1), E. coli (2) e Neisseria gonorrhoeae e três isolados de fungos do ar, como Aspergillus terreus, A. ornatus, e Rhizopus stolonifer. Dois sorotipos diferentes de S. aureus e E. coli foram usados. Os resultados do método de difusão em ágar mostraram a resposta dependente da dose de extratos de plantas contra cepas de bactérias e fungos, enquanto alguns organismos foram considerados resistentes, e.g. E. coli (1), S. sonnei, A. terreus e R. stolonifer. A maior atividade antibacteriana foi registrada em 17.000 ± 1.732 de 100 mg/mL de extratos metanólicos de folhas contra S. pyogenes, enquanto a atividade da maioria dos patógenos diminuiu após 24 h de incubação. A maior atividade antifúngica foi relatada em 11,833 ± 1,0 contra A. ornatus a 50 mg/mL após 48 h do período de incubação. Esses achados experimentais endossam o uso de S. alba em formulações etnofarmacológicas e sugerem o uso de extratos metanólicos da referida planta para o desenvolvimento de fármacos que controlem a proliferação de doenças resistentes que causam micróbios patogênicos.
