Spontaneous bacterial peritonitis is a life-threatening complication of cirrhosis that can increase healthcare utilization. The impact of albumin administration timing on hospital resource utilization and its optimal timing is unclear, despite its efficacy in improving survival for cirrhosis patients with spontaneous bacterial peritonitis. A retrospective study was conducted to evaluate the influence of the timing of albumin administration on the length of stay and total hospital cost for patients with cirrhosis and spontaneous bacterial peritonitis who require fluid resuscitation. The study utilized de-identified data from Cerner Health Facts® data. Adult inpatients with a diagnosis of cirrhosis and SBP receiving ≥1 antibiotic and fluid resuscitation between January 1, 2009, and April 30, 2018, were included and stratified by albumin administration timing: ≤24 hours from hospital admission ("timely albumin") or >24 hours of admission or no albumin ("non-timely albumin"). We used a Kaplan-Meier curve with log-rank test to evaluate the association between timing of albumin administration and time to hospital discharge and a generalized linear model to examine the association between albumin timing and total hospital costs. We identified 1,308 hospitalizations, of which 301 contained valid cost data. The timely albumin group had a median time to discharge of 6.95 days compared to 7.78 days in the non-timely group ( = 0.02). Cost model showed that receiving timely albumin incurred 16% lower costs ( = 0.027) than patients in the non-timely albumin group. Timely albumin administration with an antibiotic regimen may shorten the length of stay and lower costs, thereby reducing hospital resource utilization in patients with cirrhosis and spontaneous bacterial peritonitis requiring fluid resuscitation.

BACKGROUND
Paracoccidioidomycosis is a neglected tropical disease caused by fungi of the genus Paracoccidioides. A wide range of symptoms is related to the disease; however, lungs and skin are the sites predominantly affected. The disease is mostly seen in people living in rural areas in Latin America.
CASE REPORT
We present a pediatric case of severe disseminated paracoccidioidomycosis that slowly responded to the antifungal treatment. Within three months, symptoms evolved into hepatosplenomegaly, necrotic cervical and abdominal lymph nodes, and splenic abscess. Clinical response to amphotericin B deoxycholate and itraconazole was slow, resulting in pleural and peritoneal cavity effusions, heart failure and shock. Amphotericin B deoxycholate was replaced by the liposomal formulation, with no response. Subsequently, prednisone was added to the treatment, which led to improvement in the clinical response. Serological Paracoccidioides antibody titers were atypical, with very low titers in the critical phase and significant increase during the convalescence phase. The infection was finally cleared up with amphotericin B deoxycholate, liposomal amphotericin B and the use of corticosteroids. Paracoccidioidomycosis serology was non-reactive two years post-discharge.
CONCLUSIONS
Due to the intense inflammatory response triggered by Paracoccidioides cells, giving low-dose prednisone for a short period of time modulated the inflammatory response and supported antifungal treatment.

BACKGROUND
The Trans Rectus Sheath Extra-Peritoneal Procedure (TREPP) is an open procedure in which the mesh is placed in the preperitoneal space and is therefore associated with less chronic post-operative inguinal pain. TREPP is primarily performed under general or spinal anesthesia, however, it is also possible to perform under sedation and local anesthesia with potentially advantages. This retrospective feasibility pilot study investigates the safety and efficiency of TREPP under local anesthesia in the outpatient clinic in comparison with Lichtenstein.
METHODS
Between 2019 and 2022, all patients who underwent an elective inguinal hernia repair under local anesthesia in the outpatient clinic operation theatre were assessed. 34 patients in the TREPP group and 213 patients in the Lichtenstein group were included. Outcomes were complications, operating time, theatre time, and early inguinal hernia recurrence within 8 weeks and 6 months post-operatively.
RESULTS
No significant differences in complications such as wound infection, hematoma, seroma, urine retention and early recurrence between TREPP and Lichtenstein were found. Post-operative pain at 8 weeks was not significantly higher after Lichtenstein (8.8% vs. 18.8%, P = 0.22). Operating time (21.0 (IQR: 16.0-27.3) minutes vs. 39.0 (IQR: 31.5-45.0) minutes, P < 0.001) and theatre time (37.5 (IQR: 30.8-42.5) minutes vs. 54.0 (IQR: 46.0-62.0) minutes, P < 0.001) was significantly shorter for TREPP.
CONCLUSION
This pilot study showed that TREPP appears to be feasible to perform safely under local anesthesia with comparable complication rates and substantially shorter operation time than Lichtenstein. These results justify further research with a larger study population and a longer period of follow up in order to provide firm conclusions.

Intrauterine appendicular perforation leading to meconium peritonitis is exceptionally rare, with few reported cases in the literature. This case underscores the diagnostic challenges and high mortality associated with neonatal appendicular perforation. Neonatal appendicitis and subsequent perforation are uncommon due to the funnel shape of the fetal appendix, which reduces susceptibility to luminal obstruction. While advances in neonatal care and diagnostic modalities have improved outcomes, challenges persist in timely diagnosis and management. We present the case of a preterm infant, one of dichorionic-diamniotic (DCDA) twins delivered via cesarean section, who developed gross abdominal distension and respiratory distress shortly after birth. Diagnostic abdominocentesis revealed meconium-stained fluid, prompting further investigation with imaging and subsequent exploratory laparotomy. Extensive adhesions and cecal perforation were observed, necessitating a cecostomy. Despite interventions, the infant's condition deteriorated, leading to a fatal outcome. Intrauterine appendicular perforation leading to meconium peritonitis is a rare and difficult-to-diagnose condition. Antenatal suspicion and early surgical intervention are crucial for improving outcomes. Factors contributing to neonatal appendicular perforation include ischemia, obstruction, and infective etiologies. Neonatal appendicular perforation is a rare but life-threatening condition requiring a high index of suspicion for prompt diagnosis and management. Advances in diagnostic tools and antenatal monitoring have contributed to improved outcomes, highlighting the importance of considering this diagnosis in cases of unexplained neonatal abdominal distension.

Review
Post-surgical abdominal adhesions, although poorly understood, are highly prevalent. The molecular processes underlying their formation remain elusive. This review aims to assess the relationship between neutrophil extracellular traps (NETs) and the generation of postoperative peritoneal adhesions and to discuss methods for mitigating peritoneal adhesions. A keyword or medical subject heading (MeSH) search for all original articles and reviews was performed in PubMed and Google Scholar. It included studies assessing peritoneal adhesion reformation after abdominal surgery from 2003 to 2023. After assessing for eligibility, the selected articles were evaluated using the Critical Appraisal Skills Programme checklist for qualitative research. The search yielded 127 full-text articles for assessment of eligibility, of which 7 studies met our criteria and were subjected to a detailed quality review using the Critical Appraisal Skills Programme (CASP) checklist. The selected studies offer a comprehensive analysis of adhesion pathogenesis with a special focus on the role of neutrophil extracellular traps (NETs) in the development of peritoneal adhesions. Current interventional strategies are examined, including the use of mechanical barriers, advances in regenerative medicine, and targeted molecular therapies. In particular, this review emphasizes the potential of NET-targeted interventions as promising strategies to mitigate postoperative adhesion development. Evidence suggests that in addition to their role in innate defense against infections and autoimmune diseases, NETs also play a crucial role in the formation of peritoneal adhesions after surgery. Therefore, therapeutic strategies that target NETs are emerging as significant considerations for researchers. Continued research is vital to fully elucidate the relationship between NETs and post-surgical adhesion formation to develop effective treatments.

Ly6C Monocytes Are Metabolically Reprogrammed in the Blood during Inflammatory Stimulation and Require Intact OxPhos for Chemotaxis and Monocyte to Macrophage Differentiation.
Acute inflammation is a rapid and dynamic process involving the recruitment and activation of multiple cell types in a coordinated and precise manner. Here, we investigate the origin and transcriptional reprogramming of monocytes using a model of acute inflammation, zymosan-induced peritonitis. Monocyte trafficking and adoptive transfer experiments confirmed that monocytes undergo rapid phenotypic change as they exit the blood and give rise to monocyte-derived macrophages that persist during the resolution of inflammation. Single-cell transcriptomics revealed significant heterogeneity within the surface marker-defined CD11bLy6GLy6C monocyte populations within the blood and at the site of inflammation. We show that two major transcriptional reprogramming events occur during the initial six hours of Ly6C monocyte mobilisation, one in the blood priming monocytes for migration and a second at the site of inflammation. Pathway analysis revealed an important role for oxidative phosphorylation (OxPhos) during both these reprogramming events. Experimentally, we demonstrate that OxPhos via the intact mitochondrial electron transport chain is essential for murine and human monocyte chemotaxis. Moreover, OxPhos is needed for monocyte-to-macrophage differentiation and macrophage M(IL-4) polarisation. These new findings from transcriptional profiling open up the possibility that shifting monocyte metabolic capacity towards OxPhos could facilitate enhanced macrophage M2-like polarisation to aid inflammation resolution and tissue repair.

BACKGROUND
Sepsis accounts for substantial morbidity and mortality motivating investigators to continue the search for pathways and molecules driving the pathogenesis of the disease. The current study examined if the novel C-type Lectin Receptor (CLR), Clec2d, plays a significant role in the pathogenesis of sepsis.
METHODS
Clec2d knockout (KO) mice were fully backcrossed onto the C57\BL6 background. Acute endotoxemia was induced with an intraperitoneal (i.p.) injection of lipopolysaccharide (LPS). Sepsis was induced in two different models, Cecal Ligation and Puncture (CLP) and Pseudomonas aeruginosa pneumonia. Both models were treated with antibiotics and fluid resuscitation. In the sepsis models, physiologic and hematologic measurements were measured at 24 hours by collecting a small sample of peripheral blood. Mortality was followed for 14 days.
RESULTS
A total of 197 mice were studied, 58 wild type (WT) and 54 knock-out (KO) in the LPS model; 27 wild type and 21 KO mice in the CLP model; and 22 WT and 15 KO mice in the pneumonia model. Clec2d KO mice had greater mortality in the LPS and CLP studies but not the pneumonia model. There were significant differences in multiple parameters determined 24 hours post sepsis between mice who would subsequently died and those lived. Consistent with previous reports in the CLP model, higher concentrations of IL-6, increased numbers of peripheral blood lymphocytes and greater renal injury were found in the dying mice. In contrast, in the pneumonia model IL-6 was higher in the surviving mice, however, the IL-6 levels in the pneumonia model (0.6 ± 0.3 ng/ml mean ± SEM) were less than 2% of the IL-6 levels of mice that died in the CLP model (41 ± 9 ng/ml, mean ± SEM). There were no differences in the lymphocyte count or renal injury between living and dying mice in the pneumonia model. In both sepsis models dying mice had lower heart rates, respiratory rates, and body temperatures. These values were also lower in the KO mice compared to the WT in CLP, but the breath rate and body temperature were increased in the KO pneumonia mice.
CONCLUSION
The C-type lectin receptor Clec2d plays a complicated role in the pathogenesis of sepsis which varies with source of infection as demonstrated in the models used to study the disease. These data highlight the heterogeneity of the responses to sepsis and provide further evidence that a single common pathway driving sepsis organ injury and death likely does not exist.

Traditional surgical treatment of widespread purulent peritonitis has some disadvantages that emphasizes the need for new approaches to postoperative care. The authors present successful treatment of diffuse purulent peritonitis using a combination of 'open abdomen' technology and VAC therapy. This approach reduces abdominal inflammation and intra-abdominal pressure. Combination of 'open abdomen' technology and VAC therapy provides effective control of inflammation and stabilization of patients with purulent peritonitis.

Immunotherapy has been shown to provide clinical benefit in selected patients with head and neck squamous cell carcinoma (HNSCC), regardless of human papillomavirus (HPV) infection, and including recurrent/metastatic (R/M) platinum refractory tumors. Hyperprogression is an uncommon negative outcome of treatment with immunotherapy. We present the case of a patient with HPV+ HNSCC who presented hyperprogression after immunotherapy and a rare metastasis location with peritoneal carcinomatosis and subcutaneous nodules. HPV+ HNSCC is related to distant recurrence after a longer interval of time and more diverse metastasis sites compared with HPV- disease. However, the literature on peritoneal metastasis in HNSCC remains limited, with few documented cases. To the best of our knowledge, this is the first case reporting peritoneal carcinomatosis after hyperprogression in HNSCC.

Microbial infection-induced sepsis causes excessive inflammatory response and multiple organ failure. An effective strategy for the treatment of sepsis-related syndromes is still needed. Rosuvastatin, a typical β-hydroxy β-methylglutaryl-CoA reductase inhibitor licensed for reducing the levels of low-density lipoprotein cholesterol in patients with hyperlipidemia, has displayed anti-inflammatory capacity in different types of organs and tissues. However, its effects on the development of sepsis are less reported. Here, we found that the administration of Rosuvastatin reduced the mortality of sepsis mice and prevented body temperature loss. Additionally, it inhibited the production of inflammatory cytokines such as tumor necrosis factor (TNF-α), Interleukin-6 (IL-6), interleukin-1β (IL-1β), and migration inhibitory factor (MIF) in peritoneal lavage supernatants of animals. The increased number of mononuclear cells in the peritoneum of sepsis mice was reduced by Rosuvastatin. Interestingly, it ameliorated lung inflammation and improved the hepatic and renal function in the sepsis animals. Further experiments show that Rosuvastatin inhibited lipopolysaccharide (LPS)-induced production of proinflammatory cytokines in RAW 264.7 macrophages by preventing the activation of nuclear factor kappa-B (NF-κB). Our findings demonstrate that the administration of Rosuvastatin hampered organ dysfunction and mitigated inflammation in a relevant model of sepsis.
