Sepsis pathophysiology involves a dysregulated immune response to infection, excessive inflammation, and immune paralysis. This study explores the relationships between cell death biomarkers (serum-soluble levels of programmed cell death protein 1 (PD-1), programmed death ligand 1 (PD-L1), and interleukin-7 (IL-7)) and the percentages of various lymphocyte subsets in relation to the severity and progression of sepsis. This prospective, observational study included 87 critically ill patients. We monitored parameters on days 1 (sepsis was diagnosed according to the Sepsis-3 Consensus) and 5. We established an IL-7 cutoff value of 1.94 pg/mL by comparing levels between a healthy control group and patients with sepsis (p < 0.0001). Lymphopenia was observed in all patients, with negative correlations between helper T lymphocytes and cytotoxic and B lymphocytes, and positive correlations involving cytotoxic lymphocytes across all groups. We found correlations between PD-1/PD-L1 and lymphocyte subsets. IL-7 showed a statistical correlation with PD-1 in non-survivors. Assessing lymphocyte levels shows potential as a biomarker for evaluating the progression of sepsis. Monitoring IL-7 levels could help assess survival, as low levels are associated with higher mortality risk. Monitoring IL-7 levels could help assess survival, as low levels are associated with higher mortality risk. Elevated PD-1/PD-L1 expression impairs costimulatory signalling, reducing T cell responses and lymphopenia, which increases the risk of nosocomial infections.

Background and Objectives: Numerous scoring systems have been introduced into modern medicine. None of the scoring systems assessed both anesthetic and surgical risk of the patient, predict the morbidity, mortality, or the need for postoperative intensive care unit admission. The aim of this study was to compare the anesthetic and surgical scores currently used, for a better evaluation of perioperative risks, morbidity, and mortality. Material and Methods: This is a pilot, prospective, observational study. We enrolled 50 patients scheduled for elective surgery. Anesthetic and surgery risk was assessed using American Society of Anesthesiologists (ASA) scale, Physiological and Operative Severity Score for the enumeration of Mortality and morbidity (P-POSSUM), Acute Physiology and Chronic Health Evaluation (APACHE II), and Surgical APGAR Score (SAS) scores. The real and the estimated length of stay (LOS) were registered. Results: We obtained several statistically significant positive correlations: ASA score–P-POSSUM (p < 0.01, r = 0.465); ASA score–SAS, (p < 0.01, r = −0.446); ASA score–APACHE II, (p < 0.01 r = 0.519); predicted LOS and ASA score (p < 0.01, r = 0.676); predicted LOS and p-POSSUM (p < 0.01, r = 0.433); and predicted LOS and APACHE II (p < 0.01, r = 0.454). A significant negative correlation between predicted LOS, real LOS, ASA class, and SAS (p < 0.05) was observed. We found a statistically significant difference between the predicted and actual LOS (p < 001). Conclusions: Anesthetic, surgical, and severity scores, used together, provide clearer information about mortality, morbidity, and LOS. ASA scale, associated with surgical scores and severity scores, presents a better image of the patient’s progress in the perioperative period. In our study, APACHE II is the best predictor of mortality, followed by P-POSSUM and SAS. P-POSSUM score and ASA scale may be complementary in terms of preoperative physiological factors, providing valuable information for postoperative outcomes.

Background and Objectives: Sepsis involves a dysregulated host response, characterized by simultaneous immunosuppression and hyperinflammation. Initially, there is the release of pro-inflammatory factors and immune system dysfunction, followed by persistent immune paralysis leading to apoptosis. This study investigates sepsis-induced apoptosis and its pathways, by assessing changes in PD-1 and PD-L1 serum levels, CD4+ and CD8+ T cells, and Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation (APACHE II) severity scores. Materials and Methods: This prospective, observational, single-centre study enrolled 87 sepsis patients admitted to the intensive care unit at the County Emergency Clinical Hospital in Târgu Mureș, Romania. We monitored the parameters on day 1 (the day sepsis or septic shock was diagnosed as per the Sepsis-3 Consensus) and day 5. Results: Our study found a statistically significant variation in the SOFA score for the entirety of the patients between the studied days (p = 0.001), as well as for the studied patient groups: sepsis, septic shock, survivors, and non-survivors (p = 0.001, p = 0.003, p = 0.01, p = 0.03). On day 1, we found statistically significant correlations between CD8+ cells and PD-1 (p = 0.02) and PD-L1 (p = 0.04), CD4+ and CD8+ cells (p < 0.0001), SOFA and APACHE II scores (p < 0.0001), and SOFA and APACHE II scores and PD-L1 (p = 0.001 and p = 0.01). On day 5, we found statistically significant correlations between CD4+ and CD8+ cells and PD-L1 (p = 0.03 and p = 0.0099), CD4+ and CD8+ cells (p < 0.0001), and SOFA and APACHE II scores (p < 0.0001). Conclusions: The reduction in Th CD4+ and Tc CD8+ lymphocyte subpopulations were evident from day 1, indicating that apoptosis is a crucial factor in the progression of sepsis and septic shock. The increased expression of the PD-1/PD-L1 axis impairs costimulatory signalling, leading to diminished T cell responses and lymphopenia, thereby increasing the susceptibility to nosocomial infections.

Background and Objectives: The severe systemic response to urinary tract infections known as urosepsis is associated with significant morbidity and mortality rates. The neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) are simple blood tests that could be useful in predicting the outcome of sepsis. Materials and Methods: A prospective observational study was conducted at a tertiary care hospital, where our team studied 223 patients with urosepsis. The patients underwent Sepsis-3 criteria-based urosepsis and septic shock stratification followed by survivor and non-survivor classification. Clinical scores (Sequential Organ Failure Assessment-SOFA, National Early Warning Score-NEWS), laboratory markers (NLR, PLR, PCT-procalcitonin), and patient outcomes were then analysed. Results: An admission NLR ≥ 13 was a strong predictor of septic shock (adjusted Odds Ratio (OR) 2.10, 95% Confidence Interval (CI) 1.25–3.54) and in-hospital mortality (adjusted OR 2.45, 95% CI 1.40–4.28). While the prognostic value of the PLR remained moderate, the NLR demonstrated superior predictive power. As easily measurable biomarkers, the NLR and PLR provide valuable information to help clinicians identify at-risk patients during the early stages of urosepsis. Conclusions: The NLR is an independent predictor with high predictive value for both septic shock and mortality, performing as well as established clinical scores. The combination of these parameters with clinical assessments could lead to better early decisions and improved outcomes for patients with urosepsis.

Obesity Hypoventilation Syndrome (OHS), also known as Pickwickian syndrome, is a complex disorder characterized by obesity (BMI > 30 kg/m2), daytime hypercapnia (PaCO2 ≥ 45 mmHg), and sleep-disordered breathing, primarily affecting individuals with severe obesity. Its diagnosis requires the exclusion of other causes of alveolar hypoventilation and involves comprehensive assessments, including clinical history, physical examination, pulmonary function tests, arterial blood gases, and sleep studies. The pathophysiology of OHS involves mechanical constraints from excessive adipose tissue, diminished central respiratory drive often linked to leptin resistance, mitochondrial dysfunction, and oxidative stress, all contributing to impaired ventilation and systemic inflammation. The condition often coexists with obstructive sleep apnea (OSA), exacerbating nocturnal hypoxia and hypercapnia, which can lead to severe cardiopulmonary complications such as pulmonary hypertension and right-sided heart failure. Epidemiologically, the rising global prevalence of obesity correlates with an increased incidence of OHS, yet underdiagnosis remains a significant challenge, often resulting in critical presentations like acute hypercapnic respiratory failure. Management primarily centers on non-invasive ventilation modalities like CPAP and BiPAP, with an emphasis on individualized treatment plans, continuous monitoring, and addressing comorbidities such as hypertension and diabetes. Pharmacological interventions are still evolving, focusing on supportive care and metabolic regulation. Long-term adherence, psychological factors, and complications like ventilator failure or device intolerance highlight the need for ongoing multidisciplinary management. Overall, advancing our understanding of OHS’s multifactorial mechanisms and optimizing tailored therapeutic strategies are crucial for improving patient outcomes and reducing mortality associated with this increasingly prevalent syndrome.

The COVID-19 pandemic has increased the need for intensive care personnel. Romania has a low number of physicians per inhabitant. The stress of pandemics upon an already weak medical health system triggered some psychological effects upon burnt-out personnel. The main objective is to provide an insight into the psychological status of Romanian ICU personnel by evaluating their level of anxiety. The secondary objectives aim to identify the level of post-traumatic stress disorder and anxiety in different groups and to identify the personnel most affected psychologically. This study enrolled adult responders from the ICU of Târgu Mureș Emergency Clinical County Hospital, Romania, participating voluntarily. The evaluation tests were the State-Trait Anxiety Inventory and Post-Traumatic Stress Test. Out of the 126 eligible participants, 87 adult employees were enrolled—with a 69% response rate. The study comprised three groups: doctors, nurses, and auxiliary personnel. All three groups scored for moderate anxiety symptoms. COVID-19-related anxiety was strongly correlated with age and number of working years in all groups. Increased PTSD scores were observed in doctors and nurses. All ICU personnel who dealt with COVID-19 patients presented with moderate anxiety and post-traumatic stress disorder symptoms. The years of ICU experience had a positive impact on anxiety symptoms.
