Infections of Biliary Tract

Biliary tract infections include cholangitis and cholecystitis. They are associated with high morbidity and mortality in elderly patients with comorbid disease. The most common infecting organisms are Enterobacteriaceae ascending from the gastrointestinal tract, Gram-positive pathogens like Enterococci spp.; the infections are rarely caused by fungi, viruses, and parasites. The prime reason for biliary tract infections is the ascending infection due to the reflux of duodenal contents and also the blood-borne infection or infection spreading through the portal-venous channels. The other predisposing conditions causing biliary tract infections include critical illnesses such as trauma, burns, sepsis, HIV infection, immunosuppression, diabetes, non-biliary surgery, and childbirth. The infection is reduced by β-lactam antibiotics or their derivatives, cephalosporins, carbapenems, fluoroquinolones, etc. Empiric treatment with piperacillin/tazobactam or a cephalosporin with or without metronidazole is recommended for moderate and severe acute cholecystitis irrespective of whether there is growth by culture. Patients with severe cholecystitis are unfortunately difficult to identify properly, both clinically and radiologically, because clinical symptoms are unexpected, and imaging investigations are frequently ambiguous. However, there are significant differences in morbidity and death rates between individuals with mild cholecystitis and those with severe cholecystitis. Preventing related consequences requires early identification and effective therapy of individuals at risk of severe cholecystitis

ISOLATION OF MULTI DRUG RESISTANT BACTERIA FROM BORE WATER SAMPLES IN AND AROUND VISAKHAPATNAM

Objective: The aim of the present study was to determine the levels of groundwater contamination by isolating total coliforms, fecal coliforms, and bacterial pathogens. Methods: A total of 32 water samples, comprising 5 samples from each GVMC urban area zone, Visakhapatnam were randomly collected from different areas. Evaluation of Total and fecal coliform counts was done by using multiple-tube fermentation technique and were reported as the most probable number (MPN) of organisms present per 100 ml of sample. Results: The samples collected from the zones Yendada (zone I), Marripalem (zone IV), Chinna musidiwada (zone VI) showed the highest total and fecal coliform counts (MPN>180). Nearly 30 samples (94%) yielded bacterial isolates. Among the isolates Pseudomonas spp. showed highest susceptibility to cefepime and imipenem antibiotics. All the microorganisms isolated were multidrug resistant with a multidrug antibiotic resistant index more than 0.2. Conclusion: These multidrug-resistant (MDR) organisms are considered as a major threat to the public health and should receive more attention

The COVID-19 vaccination acceptance/hesitancy rate and its determinants among healthcare workers of 91 Countries: A multicenter cross-sectional study.

The aim of this study was to investigate the COVID-19 vaccination acceptance rate and its determinants among healthcare workers in a multicenter study. This was a cross-sectional multi-center survey conducted from February 5 to April 29, 2021. The questionnaire consisted of 26 items in 6 subscales. The English version of the questionnaire was translated into seven languages and distributed through Google Forms using snowball sampling; a colleague in each country was responsible for the forward and backward translation, and also the distribution of the questionnaire. A forward stepwise logistic regression was utilized to explore the variables and questionnaire factors tied to the intention to COVID-19 vaccination. 4630 participants from 91 countries completed the questionnaire. According to the United Nations Development Program 2020, 43.6 % of participants were from low Human Development Index (HDI) regions, 48.3 % high and very high, and 8.1 % from medium. The overall vaccination hesitancy rate was 37 %. Three out of six factors of the questionnaire were significantly related to intention to the vaccination. While 'Perceived benefits of the COVID-19 vaccination' (OR: 3.82, p-value<0.001) and 'Prosocial norms' (OR: 5.18, p-value<0.001) were associated with vaccination acceptance, 'The vaccine safety/cost concerns' with OR: 3.52, p-value<0.001 was tied to vaccination hesitancy. Medical doctors and pharmacists were more willing to take the vaccine in comparison to others. Importantly, HDI with OR: 12.28, 95 % CI: 6.10-24.72 was a strong positive determinant of COVID-19 vaccination acceptance. This study highlighted the vaccination hesitancy rate of 37 % in our sample among HCWs. Increasing awareness regarding vaccination benefits, confronting the misinformation, and strengthening the prosocial norms would be the primary domains for maximizing the vaccination coverage. The study also showed that the HDI is strongly associated with the vaccination acceptance/hesitancy, in a way that those living in low HDI contexts are more hesitant to receive the vaccine

Self-reported antibiotic stewardship and infection control measures from 57 intensive care units: An international ID-IRI survey

We explored the self-reported antibiotic stewardship (AS), and infection prevention and control (IPC) activities in intensive care units (ICUs) of different income settings. A cross-sectional study was conducted using an online questionnaire to collect data about IPC and AS measures in participating ICUs. The study participants were Infectious Diseases-International Research Initiative (IDI-IR) members, committed as per their institutional agreement form. We analyzed responses from 57 ICUs in 24 countries (Lower-middle income (LMI), n = 13; Upper-middle income (UMI), n = 33; High-income (HI), n = 11). This represented (similar to 5%) of centers represented in the ID-IRI. Surveillance programs were implemented in (76.9%-90.9%) of ICUs with fewer contact precaution measures in LMI ones (p = 0.02); (LMI:69.2%, UMI:97%, HI:100%). Participation in regional antimicrobial resistance programs was more significantly applied in HI (p = 0.02) (LMI:38.4%,UMI:81.8%,HI:72.2%). AS programs are implemented in 77.2% of institutions with AS champions in 66.7%. Infectious diseases physicians and microbiologists are members of many AS teams (59%&amp;50%) respectively. Unqualified healthcare professionals(42.1%), and deficient incentives(28.1%) are the main barriers to implementing AS. We underscore the existing differences in IPC and AS programs' implementation, team composition, and faced barriers. Continuous collaboration and sharing best practices on APM is needed. The role of regional and international organizations should be encouraged. Global support for capacity building of healthcare practitioners is warranted.
