Introduction: Sepsis is a significant cause of morbidity and mortality worldwide. Current clinical practice, however, lacks reliable diagnostic indicators for it and its prognosis. Aim: The present study aimed to investigate the efficacy of delta neutrophil index (DNI), which reflects the proportion of circulating immature granulocytes, in predicting infections and sepsis. Materials and methods: A prospective non-interventional single-center clinical follow-up study was performed in a Bulgarian ICU between January 1, 2017 and May 31, 2018. We analyzed adult patients: 45 patients met the sepsis criteria, as defined in SEPSIS-3, whereas 37 were infected patients fulfilling no criteria of sepsis. Logistic regression and Roc-curve analysis were used to evaluate the severity and prognostic value of DNI as a prediction marker in critically ill septic patients. Results: The results have shown that at DNI values of 1.4 there is 73% sensitivity and 87% specificity (AUC 0.764, 95% CI 0.650–0.878, p=0.0001) to assume the presence of sepsis. Additionally, DNI was significantly associated with the severity of the condition of patients, the organ dysfunction and the IL-8 marker. Conclusions: DNI may serve as a useful marker for early diagnosis of sepsis and could support decision making process regarding its treatment at an early stage of a disease development.

Unveiling Respiratory Challenges in Cerebral Palsy: A Comprehensive Review

Children diagnosed with cerebral palsy (CP) frequently face a range of intricate health challenges that go beyond their main condition. Respiratory problems represent one of the most crucial factors contributing to morbidity and mortality. This review employed a systematic approach to identify and collate recent findings on the respiratory microbiota in children with CP. The review emphasizes notable microbial alterations in the respiratory systems of children with CP, marked by a decrease in beneficial bacteria (such as Corynebacterium spp. and Dolosigranulum spp.) and an increase in opportunistic pathogens like Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumonia. These changes probably increase the vulnerability of children with CP to frequent respiratory infections, ongoing inflammation, and infections that are resistant to antibiotics. Key factors influencing the composition of microbiota include living in urban areas, socioeconomic factors, seasonal variations, vaccination status, dietary habits, breastfeeding, etc. Although new research has shed significant light on this topic, there are still considerable gaps in our understanding of how these microbial communities develop and interact with the immune responses of the host. Future research should focus on longitudinal studies to track microbiota changes over time and identify interventions that optimize respiratory health in CP.

In 2019, the world faced another of the potentially deadly viruses affecting humanity. The new virus, COVID-19, was extremely virulent when it first appeared, with aggressive behaviour toward people unprepared at the time to deal with the infection.Months later, we already know much about its pathophysiology, but new and unknown pathophysiological aspects of the disease are revealed in time. The clinical picture is not unequivocal at times, with symptoms quite unlike those we have previously considered normal in respiratory infections tending to appear. There have been reports of an increase in the frequency of neoplasms or disease progression due to delayed treatment. Treatment of COVID-19 is still a mirage, and people are struggling with the implications for recovery, the health and economic crisis, and the psychological effects of traumatic stress.

Rhinovirus/enterovirus complex is traditionally associated with self limiting, uncomplicated upper respiratory tract infections. However, emerging clinical evidence suggests a more pathogenic profile. Members of the genus Enterovirus (family Picornaviridae) are increasingly recognized for their capacity to invade the lower respiratory tract, leading to significant pulmonary morbidity. Recent studies indicate that RV/EV infections are frequently complicated by bacterial coinfection and the development of complicated pneumonia. This case report presents the clinical course of a 64-year-old welder admitted to the intensive care unit due to severe right lobar pneumonia and severe hypoxemia. Investigations confirmed invasive pneumococcal disease with Streptococcus pneumoniae bacteremia, with a concomitant rhinovirus/enterovirus infection. This viral-bacterial interplay induced acute systemic inflammation along with coagulopathy, respiratory dysfunction, and multiorgan failure that fulfilled the Sepsis-3 definitions. The clinical course was prolonged and fluctuating despite the introduction of a prompt, well-focused intravenous antibiotic regimen. This case demonstrates the occupational susceptibility of welders who have additional risk factors (i.e., smoking and inadequate vaccination status) to invasive pneumococcal disease. Additionally, this case report highlights the potential for precipitous decline in the context of a viral and bacterial co-infection and therefore, the need for early recognition of potential sepsis along with prompt implementation of antimicrobial therapy.
