Nurses’ experiences in neonatal sepsis prevention and management: a qualitative cross-sectional study at selected hospitals in a metropolitan area

BackgroundNeonatal sepsis represents a significant cause of morbidity and mortality among infants in healthcare settings. This study explored nurses’ experiences in preventing and managing neonatal sepsis in the Tamale metropolis.MethodsAn exploratory, descriptive qualitative cross-sectional study design was used, and data was collected using semi-structured interviews. The sample size was determined at the point of data saturation of fifteen participants. Thematic analysis was employed to identify codes, subthemes, and themes within the interview transcripts.ResultsThree major challenges nurses face in preventing and managing neonatal sepsis, including (1) the absence of a protocol for handling newborns upon admission, (2) an excessive workload that made it difficult for staff to follow infection prevention protocols, and (3) inadequate, obsolete and/or lack of equipment that caused devices to be overused. The nurses also identified critical psychological and emotional difficulties they encounter as a result of working within such a stressful environment. Other activities nurses conducted were handwashing before and after every procedure, infection prevention, and separating the babies in the incubator. In managing babies with neonatal sepsis, nurses provided daily treatment, hygiene care, and supported activities of living. The nurses also assert that the availability of resources, appropriate staff, and critical skills are important for preventing and managing neonatal sepsis.ConclusionThe lack of basic working consumables like gloves, syringes, and needles, inadequate staff, and lack of defined protocol of care were identified as critical challenges that hamper the care provided in neonatal care units. Hospital authorities must focus attention on addressing the critical challenges faced by neonatal care units. Also, measures should be instituted to address the emotional and psychological concerns associated with nursing care. Future research must consider the level of influence of each of the challenges enumerated on nurses’ overall health.

Histopathological Description of Mouse Liver in a Sepsis Model Infected with Escherichia coli Treated with Paederia foetida L. Leaf Extract for Sepsis Prevention

The leaf of Paederia foetida L. is one type of medicinal plant that can be used as a preventive medicine for sepsis. This plant contains secondary metabolites such as alkaloids, flavonoids, triterpenoids, saponins, and other active compounds. The objective of this study was to determine the histopathological description of the liver in a mouse sepsis model infected with E. coli, with the administration of Paederia foetida L. leaf extract for sepsis prevention, and to ascertain the influence and effective dosage of the leaf extract as a preventive measure against liver histopathology in the sepsis model induced by E. coli. The method employed was a Completely Randomized Design (CRD). The study used 24 male white mice divided into 6 (six) groups. Data analysis was conducted using One Way ANOVA. The results of the study revealed the histopathological profile of liver cell degeneration in group PI (100mg/kg BW) at 20.79%±0.03, group PII (200mg/kg BW) at 21.63%±0.02, and group PIII (500mg/kg BW) at 9.08%±0.02. Necrosis rates were observed in group PI (100mg/kgBW) at 22.62%±0.04, group PII (200mg/kg BW) at 17.63%±0.02, and group PIII (500mg/kg BW) at 6.05%±0.02. The presence of polymorphonuclear leukocytes (PMN) was detected in group PI (100mg/kgBW) at 39.56%±0.03, group PII (200mg/kgBW) at 28.05%±0.02, and group PIII (500mg/kg BW) at 18.45%±0.03. The test results showed a significant effect of P. foetida L. leaf extract as a preventive measure against liver histopathology in the mouse sepsis model infected with E. coli, with significant values for necrosis (p=0.000), cell degeneration (p=0.000), and PMN (p=0.000). The most effective dosage of P. foetida L. leaf extract as a preventive measure against liver histopathology in the mouse sepsis model infected with E. coli was the dosage used in group PIII (500mg/kgBW).

Complications associated with loop ileostomy reversal delayed greater than twelve months.

Diverting loop ileostomy is performed after colectomy to allow for anastomotic healing, and prevention of pelvic sepsis when an anastomotic leak occurs. There is no consensus on the optimal timing of ileostomy closure, and there is limited data on complications associated with ileostomy closure greater than 12 months after creation. The aim of this study is to investigate outcomes of delayed loop ileostomy closure greater than 12 months after creation. Patients undergoing loop ileostomy closure between 2013 and 2023 at Carilion Medical Center, in Roanoke, VA were reviewed. Cohorts compared were defined as Control Group (closure < 4 months) and Delayed Group (closure > 12 months). Demographics and outcomes were compared. Statistical comparisons were performed using either Wilcoxon rank sum test, Pearson's Chi-squared test or Fisher's exact test. Statistical modeling included binary logistic regression for 30-day readmissions and a generalized linear modeling for days till bowel function returns. Adjusted odds ratios, confidence intervals, and p-values were calculated. There were 135 patients in the Control Group and 19 patients in the Delayed Group. Demographics were similar between the groups except for a higher percentage of patients with diabetes, renal failure and history of cancer in Delayed Group (all p < 0.05). Operative time was longer for Delayed loop ileostomy closure (p < 0.05). Patients in the Delayed Group demonstrated a higher hospital readmission rate within 30 days (p < 0.05). Both groups had similar return of bowel function on post-operative day 2, similar length of stay, and similar rates of postoperative ileus (p = NS). Delayed loop ileostomy closure more than 12 months after creation does not delay return of bowel function but may lead to higher hospital readmission rates within 30 days.

Epidemiological characteristics and impact of sepsis on survival after osteoporotic pelvic fracture in Austria.

We performed a retrospective nationwide register-based cohort study which included all in-hospital patients aged ≥ 50 with pelvic fracture (PF) between 2010 and 2018 in Austria. We identified patients who were hospitalized with sepsis within 180 days following a PF event. Aetiology of sepsis was divided by unspecified, gram positive, gram negative and other. Among 59,081 patients hospitalized with PF between 2010 and 2018 we identified 619 (1.05%) patients who were hospitalized with sepsis within 180 days following PF. The cumulative incidence risk of sepsis within 180 days after PF was significantly higher in males (1.4%, 95% CI 1.2%-1.5%) as compared to females (0.92%, 95% CI 0.83%-1.0%), p < 0.001. In the cohort of patients with sepsis, the one-year mortality was 50.4%. Mortality risk was greater for patients who developed sepsis, independently of age, sex and comorbidity status (HR 3.12, 95% CI 2.83-3.44, p < 0.001) as compared to patients without sepsis. With a very high one-year mortality risk among those who develop sepsis, our study emphasizes the substantial impact of sepsis on long term survival in fractured patients. These findings underscore the critical need for sepsis prevention and early detection and management to mitigate its detrimental effects on patient outcomes.

Knowledge and Practice Regarding Prevention of Puerperal Sepsis among Postnatal Mothers in Selected Areas of Kamrup (M), Assam

Background: Postpartum period or puerperium is the period following childbirth during which the body tissues especially the pelvic organs revert back approximately to the prepregnant state both anatomically and physiologically. Each mother has to adjust the physical changes in her own body due to involution and lactation as well as puerperal complication which may occur. Title of the study: A study to assess the knowledge and practice regarding prevention of puerperal sepsis among postnatal mothers in selected areas of Kamrup (M), Assam. Methodology: A quantitative survey approach was adopted to assess the knowledge and practice regarding prevention of puerperal sepsis among postnatal mothers in selected areas of Kamrup (M), Assam. 81 postnatal mothers were selected using multistage simple random sampling technique from selected areas (Lalganesh, Bank Colony, Adagudam, Sankar Nagar, Kailashpur, Sreebhumi Nagar, Hillview Road, Odalbakra, Gobinda Nagar under Odalbakra MPHC of Dhirenpara zone) Kamrup(M), Assam. A structured interview questionnaire and checklist were used to assess the knowledge and practice of the postnatal mothers regarding prevention of puerperal sepsis

Association of 28-day mortality with non-high-density lipoprotein cholesterol and the high-density lipoprotein cholesterol ratio (NHHR) in patients with sepsis: Results of MIMIC-IV database analysis

BackgroundThe correlation between lipid profiles and sepsis has received increasing attention. The ratio of non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol (NHHR) is one of the key lipid profiles. However, in-depth exploration of the correlation between NHHR and the mortality risk of patients with sepsis is limited.MethodsData from the MIMIC-IV (v2.2) database, we review the NHHR relevance and the sepsis severity index using Spearman’s correlation analysis. Additionally, we research NHHR associated with sepsis patients’ survival rate of 28 days using Cox regression analyses of continuous and categorical models. To further validate our findings, we conducted subgroup and sensitivity analyses.ResultsThe study involved 3,142 patients diagnosed with sepsis, according to 28 days after in-hospital survival condition, divided into two groups. In this study, 2932 patients were in the survival group and 210 patients died within 28 days (mortality group). Of note, the mean NHHR of patients in the mortality group exceeded that of the survival group (3.5 vs. 2.9). Additionally, NHHR was positively correlated with the severity index. After adjusting for demographic and laboratory data, an increased NHHR was positively correlated with higher sepsis mortality risk (OR = 1.06; 95% CI: 1.02–1.11; P = 0.013). Subgroup analysis shown the same results. Contributors were be categorized into two groups based on NHHR levels, with a threshold of 2.61. Contrast the mortality risk between low-NHHR group and high-NHHR group, high-NHHR show greater mortality risk on 28-day, 60-day, 90-day, in ICU, and in hospital.ConclusionElevated NHHR is to be correlated with an increased risk of mortality in patients with sepsis. Further research on NHHR may contribute to advancements in sepsis prevention and treatment.

Source Control and Antibiotics in Intra-Abdominal Infections.

Intra-abdominal infections (IAIs) account for a major cause of morbidity and mortality, representing the second most common sepsis-related death with a hospital mortality of 23-38%. Prompt identification of sepsis source, appropriate resuscitation, and early treatment with the shortest delay possible are the cornerstones of management of IAIs and are associated with a more favorable clinical outcome. The aim of source control is to reduce microbial load by removing the infection source and it is achievable by using a wide range of procedures, such as definitive surgical removal of anatomic infectious foci, percutaneous drainage and toilette of infected collections, decompression, and debridement of infected and necrotic tissue or device removal, providing for the restoration of anatomy and function. Damage control surgery may be an option in selected septic patients. Intra-abdominal infections can be classified as uncomplicated or complicated causing localized or diffuse peritonitis. Early clinical evaluation is mandatory in order to optimize diagnostic testing and establish a therapeutic plan. Prognostic scores could serve as helpful tools in medical settings for evaluating both the seriousness and future outlook of a condition. The patient's conditions and the potential progression of the disease determine when to initiate source control. Patients can be classified into three groups based on disease severity, the origin of infection, and the patient's overall physical health, as well as any existing comorbidities. In recent decades, antibiotic resistance has become a global health threat caused by inappropriate antibiotic regimens, inadequate control measures, and infection prevention. The sepsis prevention and infection control protocols combined with optimizing antibiotic administration are crucial to improve outcome and should be encouraged in surgical departments. Antibiotic and antifungal regimens in patients with IAIs should be based on the resistance epidemiology, clinical conditions, and risk for multidrug resistance (MDR) and Candida spp. infections. Several challenges still exist regarding the effectiveness, timing, and patient stratification, as well as the procedures for source control. Antibiotic choice, optimal dosing, and duration of therapy are essential to achieve the best treatment. Promoting standard of care in the management of IAIs improves clinical outcomes worldwide. Further trials and stronger evidence are required to achieve optimal management with the least morbidity in the clinical care of critically ill patients with intra-abdominal sepsis.

Improving prevention and early detection of sepsis among patient groups at risk: Introducing a model for a multimodal information campaign-The SepWiss study protocol.

Sepsis is a life-threatening organ dysfunction due to a dysregulated host response to infection. Annually, sepsis leads to approx. 90.000 deaths in Germany. Risk factors include amongst others older age (>60), innate or acquired dysfunction of the immune system, and underlying chronic diseases of the lung, heart, liver, or kidneys. The manifestation of sepsis is a medical emergency, and patient outcomes depend on timely diagnosis and immediate treatment. In addition, vaccinations e.g., against pneumococci or influenza virus, are a highly effective public health tool to prevent the most common underlying infections that may lead to sepsis. However, a lack of public awareness for the relevance of vaccination and detecting sepsis as an emergency underlines the need for public health interventions that address these issues. SepWiss aims to evaluate the effects of a multimodal information campaign designed to address this lack of awareness among the risk population in Germany. SepWiss is an intervention at state level, consisting of a multimodal information campaign targeting risk groups in the German federal states of Berlin and Brandenburg (intervention region). Based on available evidence, various information formats were developed and implemented by outdoor advertising, social media, educational formats and through stakeholders' platforms, starting in August 2021. The control region comprises of the remaining 14 German federal states. We will analyze vaccination coverage (primary outcome), and sepsis knowledge, the ability to detect sepsis as an emergency, and attitude towards vaccination (secondary outcomes) amongst the risk population in a controlled before-after comparison. The implementation is accompanied by a mixed-method process evaluation. SepWiss is the first project of its kind to evaluate a complex multi-faceted evidence-based information campaign with regards to the topics of vaccination coverage, and the importance of sepsis detection and prevention for the most vulnerable populations in Germany. Results will be valuable for informing further nationwide campaigns. German Registry for Clinical Trials: DRKS00024475. Registered February 24th, 2021.

The preventative effects of Lactococcus Lactis metabolites against LPS-induced sepsis.

Sepsis is a syndrome of organ dysfunction caused by a dysregulated host response to infection and septic shock. Currently, antibiotic therapy is the standard treatment for sepsis, but it can lead to drug resistance. The disturbance of the gut microbiota which is affected by sepsis could lead to the development of organ failure. It is reported that probiotics could shape the gut microbiota, potentially controlling a variety of intestinal diseases and promoting whole-body health. In this study, we evaluated the preventive effects of intra- and extracellular products of probiotics on sepsis. The extracellular products of Lactococcus lactis (L. lactis) were identified through the in vivo cell experiments. The preventive effect and mechanism of L. lactis extracellular products on mouse sepsis were further explored through HE staining, mouse survival rate measurement, chip analysis, etc. L. lactis extracellular products increase cell survival and significantly reduce inflammatory factors secreted in a cellular sepsis model. In in vivo experiments in mice, our samples attenuated sepsis-induced pulmonary edema and inflammatory infiltrates in the lungs of mice, and reduced mortality and inflammatory factor levels within the serum of mice. Finally, the mechanism of sepsis prevention by lactic acid bacteria is suggested. Extracellular products of L. lactis could effectively prevent sepsis episodes. In animal experiments, we reported that extracellular products of L. lactis can effectively prevent sepsis, and preliminarily discussed the pathological mechanism, which provides more ideas for the prevention of sepsis. In the future, probiotics may be considered a new way to prevent sepsis.

Research progress on the role of pyroptosis in sepsis-related coagulation disorder

Sepsis is a common and severe infectious disease, and its associated coagulation dysfunction can cause disseminated intravascular coagulation (DIC) and organ failure, leading to a significant increase in mortality. Pyroptosis is a form of programmed cell death mediated by caspase-1 in the classical pathway and caspase-4/caspase-5/caspase-11 in the non-classical pathway, along with the effector molecule gasdermin (GSDM) family. Recent studies have shown that pyroptosis plays an important role in the development of coagulation disorders in sepsis. Pyroptosis leads to the formation of cytoplasmic membrane pores, cell swelling and membrane rupture, as well as the release and enhanced activity of procoagulant contents, strongly promoting the development of systemic coagulation activation and DIC in sepsis. Therefore, exploring the role and molecular mechanisms of pyroptosis in sepsis-related coagulation disorders is of great significance for the prevention and treatment of sepsis. This article provides a review of the mechanisms involved in pyroptosis and coagulation disorders in sepsis, as well as the role and mechanisms of pyroptosis in sepsis-associated coagulation disorders to provide new ideas for sepsis related research.

***ECD*** maternal C-reactive protein as a predictor of neonatal sepsis

ABSTRACT Systemic bacterial infection in the newborn has a significant impact on neonatal mortality and morbidity. Non-invasive prenatal markers of risk could be useful in the prediction and prevention of neonatal sepsis. We evaluated the association of maternal third-trimester serum level of C-Reactive Protein (CRP) with neonatal sepsis in a sample of infants in the JAKids pregnancy and birth cohort study. A population-based nested case–control design was used to identify cases and controls of neonatal sepsis from the subset of infants in the JAKids study whose mothers had serum archived in the early third trimester and who were admitted to newborn intensive care. Cases were 25 neonates with neonatal sepsis identified from hospital records. Controls were a random sample of 62 sepsis-free neonates matched to cases within three gestational age strata – ≤32 weeks, 33–36 weeks, and ≥37 weeks. Mothers of neonatal sepsis cases ≥37 weeks had significantly higher mean levels of maternal CRP protein than mothers of controls (11.0 mg/dL ± 3.0 vs. 8.7 mg/dL ± 5.9; p < .05). Differences in maternal CRP were not found in sepsis cases born ≤32 weeks (9.5 mg/dL ± 4.2 vs 5.8 mg/dL ± 4.0, p = .23) nor in sepsis cases born at 33–36 weeks (9.0 mg/dL ± 3.6 vs 11.9 mg/dL ± 7.8, p = .34). Maternal third-trimester C-reactive protein levels were elevated in mothers of term-born neonates with sepsis, but not in the mothers of preterm neonates with sepsis.

The Dysregulation of Essential Fatty Acid (EFA) Metabolism May Be a Factor in the Pathogenesis of Sepsis.

I propose that a deficiency of essential fatty acids (EFAs) and an alteration in their (EFAs) metabolism could be a major factor in the pathogenesis of sepsis and sepsis-related mortality. The failure of corticosteroids, anti-TNF-α, and anti-interleukin-6 monoclonal antibodies can be attributed to this altered EFA metabolism in sepsis. Vitamin C; folic acid; and vitamin B1, B6, and B12 serve as co-factors necessary for the activity of desaturase enzymes that are the rate-limiting steps in the metabolism of EFAs. The altered metabolism of EFAs results in an imbalance in the production and activities of pro- and anti-inflammatory eicosanoids and cytokines resulting in both hyperimmune and hypoimmune responses seen in sepsis. This implies that restoring the metabolism of EFAs to normal may form a newer therapeutic approach both in the prevention and management of sepsis and other critical illnesses.

Einflussfaktoren auf die eigene Anwendung der Sepsis-Kompetenz und ihre Förderung bei Patientinnen und Patienten: Ergebnisse einer Mixed-Methods-Studie mit Gesundheitsfachpersonen

BackgroundSepsis is a life-threatening and relatively common emergency which is often recognized too late or not at all. Therefore, the “SepsisWissen” (SepsisKnowledge) project aimed to bring about changes in health care professionals’ behavior in the area of sepsis prevention and early detection. It addressed the health care professionals themselves (e. g., their own vaccination, hygiene and early detection behavior) and their patient counseling behavior. To promote this behavior, the SepsisWissen campaign included offers such as trainings or print products. The subsequent core question is: From the health professionals’ perspective, which barriers and facilitators affect their own application of sepsis competence and their promotion of their patients’ sepsis competence? MethodsThis paper was based on a cross-sectional mixed-methods study part of “SepsisWissen” witha)semi-structured interviews with 17 providers andb)a quantitative survey among 135 providers.Part a) was analyzed using qualitative oriented content analysis based on Mayring, part b) was analyzed descriptively.The interviewees included physicians, nurses, pharmacists, assistants to physicians and pharmacists and, additionally, one paramedic in the quantitative sample. Some of them had attended “SepsisWissen” trainings. ResultsThe qualitative data analysis identified 41 conducive and hindering factors, which can be assigned to the following eight major topics: 1) syndrome sepsis; 2) predisposing factors for health professionals' own acquisition and application of sepsis competence; 3) enabling factors for health professionals themselves; 4) behavior and lifestyle of patients; 5) reinforcing factors for patients; 6) public health education; 7) political, administrative, and organizational context; 8) environmental factors. In the qualitative and quantitative surveys, the suggestion to improve the sepsis competence of the population and to reduce misinformation, respectively, through public education (e.g., via schools or the media). DiscussionSepsis training for health professionals was considered as a facilitating factor for taking potential sepsis symptoms and patients’ respective statements more seriously. Future training formats should convey more explicitly how health professionals can better communicate their own sepsis knowledge to their patients. They request instruments to support their communication, such as checklists for lay persons. According to the interviews, health workers themselves need recurring external reminders for the topic of sepsis. Organizational and political conditions should be improved. From the health professionals’ point of view, it is essential to offer better reimbursement for prevention and counseling services and to allocate adequate time resources for both. ConclusionHealth professionals could increase their potential to apply and promote sepsis competence if general conditions were optimized. From their perspective, it is most important to relieve them of some of their patient counselling burden by initiating more public education.

Machine learning reveals ferroptosis features and a novel ferroptosis classifier in patients with sepsis.

Sepsis is an organ malfunction disease that may become fatal and is commonly accompanied by severe complications such as multiorgan dysfunction. Patients who are already hospitalized have a high risk of death due to sepsis. Even though early diagnosis is very important, the technology and clinical approaches that are now available are inadequate. Hence, there is an immediate necessity to investigate biological markers that are sensitive, specific, and reliable for the prompt detection of sepsis to reduce mortality and improve patient prognosis. Mounting research data indicate that ferroptosis contributes to the occurrence, development, and prevention of sepsis. However, the specific regulatory mechanism of ferroptosis remains to be elucidated. This research evaluated the expression profiles of ferroptosis-related genes (FRGs) and the diagnostic significance of the ferroptosis-related classifiers in sepsis. We collected three peripheral blood data sets from septic patients, integrated the clinical examination data and mRNA expression profile of these patients, and identified 13 FRGs in sepsis through a co-expression network and differential analysis. Then, an optimal classifier tool for sepsis was constructed by integrating a variety of machine learning algorithms. Two key genes, ATG16L1 and SRC, were shown to be shared between the algorithms, and thus were identified as the FRG signature of classifier. The tool exhibited satisfactory diagnostic efficiency in the training data set (AUC = 0.711) and two external verification data sets (AUC = 0.961; AUC = 0.913). In the rat cecal ligation puncture sepsis model, in vivo experiments verified the involvement of ATG16L1 and SRC in the early sepsis process. These findings confirm that FRGs may participate in the development of sepsis, the ferroptosis related classifiers can provide a basis for the development of new strategies for the early diagnosis of sepsis and the discovery of new potential therapeutic targets for life-threatening infections.

Prostate biopsy sepsis prevention: external validation of an alcohol needle washing protocol.

Transrectal ultrasound-guided prostate biopsy (TRUS-Bx) is associated with a 1-8% risk of post-biopsy sepsis (PBS). A recent study described an isopropyl alcohol needle washing protocol that significantly decreased PBS rates. The current study examined the efficacy of this technique in our clinic population. Data were reviewed for 1250 consecutive patients undergoing TRUS-Bx at the Charlie Norwood VA Medical Center from January 2017 to January 2023. Needle washing was adopted in February 2021. Complications occurring within 30 days after TRUS-Bx were recorded. There were 912 patients in group 1 (without needle washing) and 338 in group 2 (with needle washing). Groups had equivalent demographic features, and men of African descent comprised 70% of patients. Standard 12 core biopsies were done in 83% and 82% in groups 1 and 2, respectively (p = 0.788). Total complication rates were 4% and 2% in groups 1 and 2, respectively (p = 0.077). There were 13 sepsis events in group 1 (1.4%) and none in group 2 (p = 0.027). Clavien-Dindo Grade I-III complications occurred in 25 (2.7%) and 7 (2.1%) patients in groups 1 and 2, respectively (p = 0.505). Standard antibiotic prophylaxis (PO fluoroquinolone and IM gentamicin) was given in 80% and 86% of patients in groups 1 and 2, respectively (p = 0.030). Subset analysis limited to patients who received standard prophylaxis showed a significant difference in sepsis rates (1.5% vs 0%; p = 0.036). Adoption of isopropyl alcohol needle washing was associated with a significant decrease in PBS events.

IJCM_120A: Factors associated with neonatal sepsis in tertiary care hospitals of Mangalore: A retrospective study

Background: Neonatal sepsis remains a significant cause of morbidity and mortality globally, particularly in developing countries like India. Early and late onset sepsis present unique challenges in diagnosis and management, with maternal and neonatal factors playing crucial roles in the manifestation of the condition. Methodology: Data were collected from tertiary care hospitals affiliated with Kasturba Medical College, Mangaluru. A structured proforma was used to gather information on maternal factors, birth history, neonatal conditions, and complications. Statistical analysis was performed using Chi- square test and student’s ‘t’ test. Results: Out of 132 cases, 50.75% were early onset sepsis (EOS) and 49.25% were late onset sepsis (LOS). Blood culture reports were positive in 46.1% cases. Maternal comorbidities included gestational diabetes mellitus (GDM), antepartum hemorrhage (APH), and pregnancy-induced hypertension (PIH). Neonatal comorbidities such as convulsions, congenital malformations, neonatal jaundice, preterm birth, and low birth weight were observed. Positive blood culture reports correlated with low birth weight and preterm births. Staphylococcus aureus was the most common organism, followed by Citrobacter Spp., Enterobacter Spp., and Pseudomonas aeruginosa. Sensitivity analysis revealed varying degrees of susceptibility to different antibiotics. Conclusion: Maternal factors like GDM, APH, and PIH showed no significant correlation with neonatal sepsis, whereas neonatal factors such as low birth weight and preterm birth were associated with an increased risk. Consanguinity also emerged as a potential risk factor. Staphylococcus aureus was the predominant causative organism, with varying antibiotic sensitivities. This study underscores the importance of understanding maternal and neonatal factors in the prevention and management of neonatal sepsis.

Severe Sepsis During Treatment for Childhood Leukemia and Sequelae Among Adult Survivors

Children undergoing treatment for leukemia are at increased risk of severe sepsis, a dysregulated immune response to infection leading to acute organ dysfunction. As cancer survivors, they face a high burden of long-term adverse effects. The association between sepsis during anticancer therapy and long-term organ dysfunction in adult survivors of childhood cancer has not been examined. To determine whether severe sepsis during therapy for leukemia in childhood is associated with subsequent chronic health conditions in adult survivors. This cohort study included 644 adult survivors of childhood leukemia who were diagnosed between January 1, 1985, and July 19, 2010, and participated in the St Jude Lifetime Cohort Study. Participants were excluded if they received hematopoietic cell transplant or had relapsed leukemia. Data collection ended June 30, 2017. Data were analyzed from July 1, 2020, to January 5, 2024. Severe sepsis episodes, defined according to consensus criteria as septic shock, acute respiratory distress syndrome, or multiorgan dysfunction associated with infection occurring during anticancer therapy, were abstracted by medical record review for all participants. Common Terminology Criteria for Adverse Events-defined chronic health condition outcomes were independently abstracted. Associations between sepsis and cumulative incidence of chronic health conditions (eg, cardiovascular, pulmonary, kidney, neurological, and neurocognitive outcomes) were compared by adjusted hazard ratios from Cox proportional hazards logistic regression. Inverse propensity score weighting was used to adjust for potential confounders, including age, year of diagnosis, and leukemia type. The study sample consisted of 644 adult survivors of pediatric leukemia (329 women [51.1%] and 315 men [48.9%]; including 56 with a history of acute myeloid leukemia and 585 with a history of acute lymphoblastic leukemia) who were most recently evaluated at a median age of 24.7 (IQR, 21.2-28.3) years at a median time after leukemia diagnosis of 17.3 (IQR, 13.7-21.9) years. Severe sepsis during treatment of acute childhood leukemia occurred in 46 participants (7.1%). Participants who experienced severe sepsis during treatment were more likely to develop moderate to severe neurocognitive impairment (29 of 46 [63.0%] vs 310 of 598 [51.8%]; adjusted hazard ratio, 1.86 [95% CI, 1.61-2.16]; P < .001) significantly affecting attention, executive function, memory and visuospatial domains. Sepsis was not associated with long-term risk of cardiovascular, pulmonary, kidney, or neurological chronic health conditions. In this cohort study of long-term outcomes in survivors of pediatric leukemia, severe sepsis during anticancer therapy for leukemia was associated with a selectively increased risk for development of serious neurocognitive sequelae. Efforts to reduce the effects of anticancer therapy on long-term function and quality of life in survivors might include prevention of severe sepsis during therapy and early detection or amelioration of neurocognitive deficits in survivors of sepsis.

Causal relationship between telomere length and sepsis: a bidirectional Mendelian randomization study

Numerous observational studies have elucidated a connection between leukocyte telomere length (LTL) and sepsis, yet its fundamental cause remains enigmatic. Thus, the current study’s objective is to employ a bidirectional Mendelian randomization (MR) approach to scrutinize the causality between LTL and sepsis. We selected single nucleotide polymorphisms (SNPs) associated with LTL (n = 472,174) and sepsis from a genome-wide association study (GWAS), including Sepsis (n = 486,484, ncase = 11,643), Sepsis (28 day death in critical care) (n = 431,365, ncase = 347), Sepsis (under 75) (n = 462,869, ncase = 11,568), Sepsis (28 day death) (n = 486,484, ncase = 1896), and Sepsis (critical care) (n = 431,365, ncase = 1380), as instrumental variables (IVs). The inverse variance weighted (IVW) MR method was employed as the primary approach, and various sensitivity analyses were conducted to assess the validity of this instrument and potential pleiotropy. Using the IVW method, we uncovered a potential causal relationship between genetically predicted LTL reduction and increased susceptibility to sepsis, with an odds ratio (OR) of 1.161 [95% confidence interval (CI) 1.039–1.297, p = 0.008]. However, reverse MR analysis did not indicate any impact of sepsis on LTL. Our forward MR study highlights a potential causal relationship between LTL as an exposure and increased susceptibility to sepsis. Specifically, our findings suggest that individuals with genetically determined shorter LTL may be at an increased risk of developing sepsis. This may contribute to the development of novel diagnostic and therapeutic strategies for the prevention, diagnosis, and treatment of sepsis.

The efficacy and acceptability of anti-inflammatory omega-3 polyunsaturated fatty acid supplements in sepsis management: a network meta-analysis of randomized controlled trials

Sepsis is a critical medical condition associated with high mortality for patients. Current pharmacological strategies for sepsis management or prevention had not achieved satisfactory results. The omega-3 fatty acids, with anti-inflammatory benefits, are considered to be promising agents for sepsis management/prevention. The aim of this network meta-analysis (NMA) is to compare the efficacy of various dosages and formulations of fish oil supplements for sepsis management and sepsis prevention. The current NMA consisted of two parts: (1) sepsis management and (2) sepsis prevention. The PubMed, ClinicalKey, Embase, ProQuest, Cochrane CENTRAL, ScienceDirect, Web of Science, and ClinicalTrials.gov databases were systematically searched to date of February 22nd, 2024 for relevant randomized controlled trials (RCTs). RCTs were eligible for inclusion if they enrolled participants with a diagnosis of sepsis or who with high risk for sepsis. All NMA procedures were conducted under the frequentist model. The primary outcomes assessed are (1) mortality rate in sepsis treatment or (2) incidence of sepsis in sepsis prevention. Our NMA, based on 28 RCTs and 1718 participants (mean age=51.6 years, mean female proportion=35.6 %), showed that (1) high dose parenteral fish oil supplement yield the lowest mortality rate in sepsis management in adult patients, and (2) high dose enteral fish oil supplement yield the lowest incidence of sepsis in pediatric patients. This study provides compelling evidence that high-dose fish oil supplements provide beneficial effects for both sepsis management and sepsis prevention. Our findings provide a preliminary rationale for future large-scale RCTs to investigate the role of fish oil supplementation in sepsis management or prevention.

Use of the "Sepsis Risk Calculator" in Belgian Newborns: A Retrospective Cohort Study.

Prevention of early-onset neonatal sepsis (EONS) is a frequent reason why many newborns receive unnecessary antibiotics. The Sepsis Risk Calculator (SRC) was developed by the Kaiser Permanente Institute as a multivariate risk assessment of EONS, aiming to reduce laboratory testing and empiric neonatal antibiotic therapy. Our objective was to assess the potential of the SRC in reducing antibiotic use in our setting. Late preterm and term newborns who received antibiotics from 2019 to 2020 in a tertiary Belgian hospital were included. Newborn-specific data were collected and entered into the online SRC, retrospectively calculating a sepsis risk score and providing recommendations for antibiotic administration. False-positive indications for treatment by the SRC were estimated based on previously published data. Antibiotic therapy rates according to the SRC recommendations were compared to the actual rate of antibiotic therapy. Of 5891 births, 414 newborns received antibiotics and were eligible for this study, representing a rate of 7.6% of newborns receiving antibiotics following our current guidelines. The SRC would have recommended antibiotic administration for 2.7%, reducing antibiotic therapy by 64.5%. Of 5 possible cases of EONS, 3 would have received antibiotics in the first 24 hours according to the SRC. In this Belgian cohort, use of the SRC has the potential to significantly decrease by 64.5% the newborns that receive antibiotics. This reduction would primarily concern asymptomatic newborns. If use of the SRC was to be implemented in Belgian maternities, strict clinical surveillance practices should be ensured.
