An Observational Study on Patients With COVID-19 Infection Admitted to the Intensive Care Unit With Respect to Their Vaccination Status.

Background SARS-CoV-2 (COVID-19) created unprecedented recurrent waves of pandemic globally. Apart from COVID-19-appropriate behavior, vaccinating the population was proposed to be the most effective measure to control these outbreaks. However, the outcomes of vaccinated patients admitted to the intensive care unit (ICU) and their comparison with unvaccinated counterparts, especially in developing countries, have not been extensively studied. Materials and methods Our study examined consecutive patients with positive RT-PCR for COVID-19 admitted to the ICU from August 1, 2021, to July 31, 2022. Prior vaccination status and its relation to demographics, disease severity, mortality, and length of stay were analyzed. Results Among 436 patients admitted to the ICU, 76 (15.4%) were unvaccinated and 369 (84.6%) were vaccinated against COVID-19. Vaccinated patients were significantly older and hypertensive, and had comparatively less severity of illness than unvaccinated patients. Crude ICU and hospital mortality were significantly lower among vaccinated patients than unvaccinated patients (15.2% versus 25.4% and 16% versus 22.3%, respectively; P<0.05). Furthermore, risk-adjusted multivariate analysis demonstrated a strong but statistically nonsignificant inverse association between vaccination status and ICU mortality (odds ratio (OR)=0.540, 95% confidence interval (CI)=0.290-1.006, P=0.052). Conclusion In severe COVID-19-infected patients who required admission to the ICU, the majority were vaccinated. However, the severity of illness and hospital mortality was significantly lower among vaccinated patients with breakthrough infections.

Safety of Enteral Nutrition Practices: Overcoming the Contamination Challenges.

Enteral nutrition (EN) has host of benefits to offer to critically ill patients and is the preferred route of feeding over parenteral nutrition. But along with the many outcome benefits of enteral feeding come the potential for adverse effects that includes gastrointestinal (GI) disturbances mainly attributed to contaminated feeds. Currently, EN is practiced using blenderized/kitchen prepared feeds or scientifically developed commercial feeds. Commercial feeds based on their formulation may be divided as ready-to-mix powder formulas or ready-to-hang sterile liquid formulas. A holistic view on potential sterility of EN from preparation to patient delivery would be looked upon. These sterility issues may potentially result in clinical complications, and hence process-related errors need to be eliminated in hospital practice, since immunocompromised intensive care unit patients are at high risk of infection. This review intends to discuss the various EN practices, risk of contamination, and ways to overcome the same for better nutrition delivery to the patients. Among the various types of enteral formulas and delivery methods, this article tries to summarize several benefits and risks associated with each delivery system using the currently available literature.

Clotting Catastrophies in the Intensive Care Unit.

Clotting catastrophies are rarely encountered challenges in the Intensive Care Unit (ICU) and their presentation and progress maybe devastating and fulminant. Dramatic onset and involvement of multiple vascular beds should alert the clinician to look for these disorders. Outcomes may be improved with rapid diagnosis and prompt institution of specific therapies and interdisciplinary liaison holds the key to success. HOW TO CITE THIS ARTICLE: Sinha S, Todi SK.

Transfer Time from the Intensive Care Unit and Patient Outcome: A Retrospective Analysis from a Tertiary Care Hospital in India.

BACKGROUND AND AIMS: Patients' outcome after ICU transfer reflect hospital's post-ICU care status. This study assessed association of after-hour ICU transfer on patient outcome. SUBJECTS AND METHODS: Single-centre, retrospective analysis of data between March 2016 and April 2017 was performed at a tertiary-care hospital in India. Patient data were collected on all consecutive ICU admissions during study period. Patients were categorized according to ICU transfer time into daytime (08:00-19:59 hours) and after-hour (20:00-07:59 hours). Patients transferred to other ICUs/hospitals, died in ICU, or discharged home from ICU were excluded. Only ?rst ICU admission was considered for outcome analysis. Primary outcome-hospital mortality; secondary outcomes-ICU readmission and hospital length of stay (LOS). All analysis were adjusted for illness severity. RESULTS: Of 1857 patients admitted during study period,1356 were eligible for study; out of which 53.9% were males and 383(28%) patients transferred during after-hour. Mean age of two groups (daytime vs. after-hour 65.7±15.2 vs. 66.3±16.2 years) was similar (p = 0.7). Mean APACHE IV score was comparable between daytime vs. after-hour transfers (45.6±20.4 vs 46.8±22; p = 0.05). Unadjusted hospital mortality rate of after-hour-transfers was significantly higher compared to daytime-transfers (7.1% vs. 4.1%; p = 0.02). After adjustment with illness severity, after-hour-transfers were associated with significantly higher hospital mortality compared to daytime-transfers(aOR1.7, 95%CI 1.1,2.8; p = 0.04). Median duration of hospital LOS and ICU readmission though higher for after-hour-transfers, was not statistically significant in adjusted analysis (aORhospitalLOS1.1, 95% CI 0.8, 1.4, p = 0.5; aORreadmission 1.6, 95% CI 0.9,2.7; p = 0.06, respectively). CONCLUSION: After-hour-transfers from ICU is associated with significantly higher hospital mortality. Hospital LOS and readmission rates are similar for daytime and after-hour -transfers.

Practice Guidelines for Nutrition in Critically Ill Patients: A Relook for Indian Scenario.

BACKGROUND AND AIM: Intensive-care practices and settings may differ for India in comparison to other countries. While international guidelines are available to direct the use of enteral nutrition (EN), there are no recommendations specific to Indian settings. Advisory board meetings were arranged to develop the practice guidelines specific to Indian context, for the use of EN in critically ill patients and to overcome challenges in this field. METHODS: Various existing guidelines, meta-analyses, randomized controlled trials, controlled trials, and review articles were reviewed for their contextual relevance and strength. A systematic grading of practice guidelines by advisory board was done based on strength of the supporting evidence. Wherever Indian studies were not available, references were taken from the international guidelines. RESULTS: Based on the literature review, the recommendations for developing the practice guidelines were made as per the grading criteria agreed upon by the advisory board. The recommendations were to address challenges regarding EN versus parenteral nutrition; nutrition screening and assessment; nutrition in hemodynamically unstable; route of nutrition; tube feeding and challenges; tolerance; optimum calorie-protein requirements; selection of appropriate enteral feeding formula; micronutrients and immune-nutrients; standard nutrition in hepatic, renal, and respiratory diseases and documentation of nutrition practices. CONCLUSION: This paper summarizes the optimum nutrition practices for critically ill patients. The possible solutions to overcome the challenges in this field are presented as practice guidelines at the end of each section. These guidelines are expected to provide guidance in critical care settings regarding appropriate critical-care nutrition practices and to set up Intensive Care Unit nutrition protocols.

Genomic and phylogenetic analysis of hapatitis C virus strains from Argentina

HCV genomic characterization was performed by nucleotide sequence analysis (n=50) combined with restriction fragment length polymorphism (RFLP) of the 5UTR region in 82 isolates coresponding to different Argentine groups. Genotype 1 was detected in 70.7 percent of the samples (58 out of 82), genotype 2 in 21.9 percent (18 of 82) and genotypes 3 in the remaining 6 sera (7.3 percent). HCV ib subtype contributed with 35.3 percent to the whole population studied (29 of 82) and was detected in 6 out of 21 sporadic cases. Besides their epidemiological significance, these results should be taken into account when future vaccines are considered on the basis of geographical HCV genotypic prevalence. (AU)
