First Detection of Extensively Drug-Resistant Salmonella Typhi Isolates Harboring VIM and GES Genes for Carbapenem Resistance from Faisalabad, Pakistan.

Rapid emergence of resistance in Salmonella enterica serovar Typhi (Salmonella Typhi) against most of the available therapeutic options for typhoid has rendered its treatment more difficult. This study sought to determine the current scenario of antimicrobial resistance in local isolates of Faisalabad following several treatment failure reports. Out of 300 clinical specimens collected in 2018, 45 isolates were identified as Salmonella Typhi. To assess changes, we compared their antibiogram profile with 31 Salmonella Typhi strains isolated in 2005. The isolates collected during 2018 showed a significant rise in antimicrobial drug resistance as compared with isolates revived from the cultures of 2005, including 15 multidrug-resistant (MDR), 20 extensively drug-resistant, and 14 pan drug-resistant isolates compared with only 8 MDRs from 2005. Notably, in 2018 isolates, resistance to azithromycin was seen in 75% of the isolates. Extended-spectrum beta-lactamase production was detected in 47% of Salmonella Typhi isolates and 18% isolates showed resistance against carbapenems. The sequences of two carbapenemase genes, VIM and GES, found in Salmonella Typhi were submitted in NCBI. The carbapenem resistance is rare in Enterobacteriaceae and probably first time reported in Salmonella Typhi. H58 haplotype was identified in the 2018 Salmonella Typhi isolates and PCR-restriction fragment length polymorphism method identified 16.7% of H58 strains that belonged to lineage I, 19.4% of H58 strains that belonged to lineage II, and the remaining 63.9% that belonged to the node. The regional difference in the antimicrobial resistance trend needs effective epidemiological studies.

Knowledge, Awareness, and Perceptions Regarding Autism Among Parents in Karachi, Pakistan.

Background The prevalence of autism is growing worldwide. Owing to parents being the primary caregivers in most situations, their ability to recognize the signs and symptoms of autism and respond appropriately is of paramount importance in aiming to provide the best healthcare to autistic individuals. This study was conducted with the aim of ascertaining the parent's knowledge and awareness of autism. Methods A cross-sectional survey was conducted among parents residing in Karachi, Pakistan. We excluded any individuals belonging to the medical profession, those who have autistic children, and those who couldn't completely comprehend English and Urdu. A sample size of 339 parents was selected. A validated and pre-tested questionnaire was administered among the study participants to record demographic information, knowledge, and perceptions regarding autism and its signs and symptoms. Data were analyzed using Statistical Package for Social Sciences (SPSS version 23.0, IBM Corp., Armonk, NY, US). A knowledge score was calculated for opinions about autism and its sign and symptoms individually to reflect a participant's overall knowledge regarding autism. Results From our study population, 75% of our population had heard of autism, with those who knew of someone with the disorder displaying greater awareness. However, our participants displayed poor knowledge scores, with a mean score of 5.59 in the section concerning correct opinions on autism and that of 6.84 in the section testing knowledge of signs and symptoms. Despite this, 95.6% of the participants were willing to get their children treated, in the event of them being diagnosed with autism. Conclusion Unfortunately, our population displayed a lack of awareness and knowledge regarding autism. To fill this gap, awareness programs should be conducted to promote parent's knowledge regarding autism, so as to allow for early diagnoses and an appropriate treatment plan/therapy. On a positive note, most were willing to get their children tested and treated in case of a diagnosis. However, only a small number of participants knew of autism centers in Karachi. General practitioners are needed to play a key role in counseling parents about autism.

Barriers to Colorectal Cancer Screening in Pakistan.

Background The prevalence of colorectal cancer (CRC) is growing in Pakistan; however, there are no national screening programs or guidelines in place to curb its development. This study was conducted with the aim of ascertaining public awareness and attitudes regarding CRC and current screening practices. Furthermore, the study assessed perceived barriers which could impact future screening processes. Methods A cross-sectional, questionnaire-based study was conducted among urban dwellers of Karachi, Pakistan. We excluded any individuals belonging to the medical profession, those diagnosed previously with CRC or having any significant co-morbidity. The validated and pre-tested questionnaire was administered among the study participants to record demographic information, awareness of CRC risk factors, symptoms and screening tests. Attitudes towards screening and perceived barriers to screening were also assessed. Data were analyzed using Statistical Package for Social Sciences (SPSS version 20.0) (IBM Corp., Armonk, NY). A knowledge score, out of a total of 14 points was calculated to reflect a participant's overall knowledge regarding CRC risk factors and signs/symptoms. Results The prevalence of CRC screening in eligible individuals (50 years or older) was 2.6% in our study population. Positive attitudes towards CRC management and screening were observed, with 75.1% (n = 296) acknowledging the preventive role of screening tests. Despite this only 14.9% (n = 58) of study participants expressed a future desire to undergo screening. Major barriers to screening were reported to be "a lack of knowledge regarding the screening procedure", a "lack of screening facilities" and that the "screening procedure is too expensive". A majority (n = 285, 72.3%) of the participants expressed a greater willingness to undergo screening if their doctor recommended it. Conclusion A national CRC screening and awareness program should be launched to promote awareness and facilitate screening in risk groups. General practitioners are needed to play a key role in counseling patients and endorsing healthy screening practices.
