Abstract
Importance The spleen is often removed in laparotomy after traumatic abdominal injury, with little effort made to preserve the spleen. Objective To explore the association of surgical management (splenic repair vs splenectomy) with outcomes in patients with traumatic splenic injuries undergoing laparotomy and to determine whether splenic repair is associated with lower mortality compared with splenectomy. Design, Setting, and Participants This is a trauma registry-based cohort study using the American College of Surgeons Trauma Quality Improvement Program database from January 2013 to December 2019. Participants included adult patients with severe splenic injuries (Abbreviated Injury Scale [AIS] grades 3-5) undergoing laparotomy after traumatic injury within 6 hours of admission. Data analysis was performed from April to August 2023. Exposures Splenic repair vs splenectomy in patients with severe traumatic splenic injury. Main Outcomes and Measures The primary outcome was in-hospital mortality. Outcomes were compared using different statistical approaches, including 1:1 exact matching with consecutive conditional logistic regression analysis as the primary analysis and multivariable logistic regression, propensity score matching, and inverse-probability weighting as sensitivity analyses. Results A total of 11 247 patients (median [IQR] age, 35 [24-52] years; 8179 men [72.7%]) with a severe traumatic splenic injury undergoing laparotomy were identified. Of these, 10 820 patients (96.2%) underwent splenectomy, and 427 (3.8%) underwent splenic repair. Among patients who underwent an initial splenic salvage procedure, 23 (5.3%) required a splenectomy during the subsequent hospital stay; 400 patients with splenic preservation were matched with 400 patients who underwent splenectomy (matched for age, sex, hypotension, trauma mechanism, AIS spleen grade, and AIS groups [0-2, 3, and 4-5] for head, face, neck, thorax, spine, and lower and upper extremity). Mortality was significantly lower in the splenic repair group vs the splenectomy group (26 patients [6.5%] vs 51 patients [12.8%]). The association of splenic repair with lower mortality was subsequently verified by conditional regression analysis (adjusted odds ratio, 0.4; 95% CI, 0.2-0.9; P = .03). Multivariable logistic regression, propensity score matching, and inverse-probability weighting confirmed this association. Conclusions and Relevance In this retrospective cohort study, splenic repair was independently associated with lower mortality compared with splenectomy during laparotomy after traumatic splenic injury. These findings suggest that efforts to preserve the spleen might be indicated in selected cases of severe splenic injuries.

Abstract
A patient in his 40s with splenic angiosarcoma metastatic to the liver underwent splenectomy, chemotherapy, and partial hepatectomy before being treated on a clinical trial with CTLA4 and PD1 inhibitors. He had received pneumococcal and meningococcal vaccines post-splenectomy. On week 10, he developed grade 3 immune-related colitis, successfully treated with the anti-tumor necrosis factor-alpha inhibitor infliximab and steroids. After 4 cycles of treatment, scans showed partial response. He resumed anti-PD1 therapy, and 6 hours after the second dose of anti-PD1 he presented to the emergency room with hematemesis, hematochezia, hypotension, fever, and oxygen desaturation. Laboratory tests demonstrated acute renal failure and septicemia (Streptococcus pneumoniae). He died 12 hours after the anti-PD1 infusion from overwhelming post-splenectomy infection (OPSI). Autopsy demonstrated non-viable liver tumors among other findings. In conclusion, patients undergoing immunotherapy and with prior history of asplenia should be monitored closely for OPSI as they may be at increased risk.

Abstract
Splenic hamartomas (SHs) are uncommon, benign vascular lesions of unclear etiology and are mostly found incidentally on abdominal images, at surgery, or at autopsy. Since the first case description, in 1861, less than 50 pediatric SH cases have been reported in the literature. In this article, we have performed an analysis of all SH cases in children published in the literature to date and presented our case of an 8-year-old male with SH. These lesions in children were shown to cause symptoms more often than in the adult population. The observed SH sizes in children ranged from a few millimeters to 18 cm, and the symptomatic lesions were mostly larger or multiple. The most common clinical finding was splenomegaly. Signs of hypersplenism were present in children with a single SH larger than 4.5 cm (diameter range: 4.5-18.0 cm) and in those with multiple hamartomas, ranging from a few millimeters to 5 cm. Eighty percent of patients with available laboratory findings had hematological abnormalities such as anemia, thrombocytopenia, or pancytopenia. Other symptoms and signs included abdominal pain, recurrent infections, fever, night sweats, lethargy, growth retardation, and weight loss. The use of multiple imaging modalities may suggest the preoperative diagnosis of a splenic mass in children and determine the therapeutic approach. However, the final diagnosis of SH relies on histopathological evaluation. Surgery, including total or partial splenectomy (PS), is the mainstay of SH management. Although total splenectomy carries a greater risk of overwhelming post-splenectomy infection than PS it has remained the most performed surgical procedure in children with SH. In the majority of pediatric patients with symptomatic SH, resolution of symptoms and resolution or improvement of cytopenias occurred after surgical treatment.

Abstract
Splenectomy often accompanies distal pancreatectomy for pancreatic cancer. However, debates persist on splenic function loss impact. Prior studies in mice revealed splenectomy promotes pancreatic cancer growth by altering CD4/Foxp3 and CD8/Foxp3 ratios. The effect on other immune cells remains unclear. Clinical observations indicate splenectomy induces immunosuppression, heightening recurrence and metastasis risk. Here, we established an orthotopic pancreatic cancer model with splenectomy and observed a significant increase in tumor burden. Flow cytometry revealed elevated MDSCs, CD8+PD-1high+ T cells, and reduced CD4+ T cells, CD8+ T cells, and natural killer cells in tumors. Bulk sequencing identified increased MicroRNA (miRNA) hsa-7b-5p post-splenectomy, correlating with staging and immunosuppression. Similar results were obtained in vivo by constructing a KPC-miRNA hsa-7b-5p-sh cell line. These findings suggest that splenectomy enhances the expression of miRNA hsa-7b-5p, inhibits the tumor immune microenvironment, and promotes pancreatic cancer growth.

Abstract
Wandering spleen, or hypermobile spleen, arises from the elongation or maldevelopment of the spleen's suspensory ligaments. This condition is a rare clinical entity, primarily affecting children, with a higher prevalence among adult females in the active reproductive age group. Manifestations may include an asymptomatic abdominal mass or intermittent abdominal discomfort due to the torsion and subsequent spontaneous detorsion of the spleen. This case report details the presentation of a 14-year-old female initially misdiagnosed as having gastroenteritis who later experienced acute abdomen. Subsequent ultrasonography and computed tomography scan revealed splenic torsion, confirmed during exploratory laparotomy, which demonstrated an infarcted spleen. The definitive therapeutic intervention was a total splenectomy. This clinical entity should be taken into account in the differential diagnosis of acute abdominal pain in order to aid in early diagnosis and management. This could allow us to avoid splenectomy whenever possible and instead do splenopexy, especially in pediatric cases, as the spleen plays a crucial role in the reticuloendothelial system.

Abstract
The spleen is one of the most commonly injured organs in blunt abdominal trauma, accounting for a vast portion of solid organ injuries, and may lead to rapid haemodynamic instability, requiring urgent operative intervention. Total splenectomies result in relative immunocompromise, with a risk of overwhelming post-splenectomy infection (OPSI) post splenectomy. This case reports the surgical management of a 20-year-old male with a grade IV splenic laceration after a motor vehicle accident. The patient underwent a trauma laparotomy with a partial splenectomy because of early take-off of the upper-lobar branch of his splenic artery, with an absorbable mesh wrap to tamponade the spleen. The patient avoided the need for a total splenectomy and was discharged after six days in the hospital with an uncomplicated recovery.

Abstract
Invasive pneumococcal disease is a serious infection with an elevated case-fatality rate that can be even higher among patients with asplenia. Its impact has been blunted by the widespread use of vaccines; even recently, in 2021, two new pneumococcal conjugate vaccines emerged. The authors present a case of a 58-year-old male, splenectomised with the immunisation schedule complete, who died of invasive pneumococcal disease with a fulminant course. It is highlighted that fever in a patient with impaired splenic function is an emergency, and despite the success of immunisation in reducing pneumococcal carriage and invasive disease, serotypes continue to change. Also, the local epidemiology may help guide situations where the immunisation recommendations are dubious regarding the implementation of the new vaccines.

Abstract
PURPOSE To determine whether a novel intervention improves the adherence to guideline-based preventive measures in asplenic patients at risk of post-splenectomy sepsis (PSS). METHODS We used a prospective controlled, two-armed historical control group design to compare a novel, health action process approach (HAPA)-based telephonic intervention involving both patients and their general practitioners to usual care. Eligible patients were identified in cooperation with the insurance provider AOK Baden-Wuerttemberg, Germany. Patients with anatomic asplenia (n = 106) were prospectively enrolled and compared to a historical control group (n = 113). Comparisons were done using a propensity-score-based overlap-weighting model. Adherence to preventive measures was quantified by the study-specific 'Preventing PSS score' (PrePSS score) which includes pneumococcal and meningococcal vaccination status, the availability of a stand-by antibiotic and a medical alert card. RESULTS At six months after the intervention, we estimated an effect of 3.96 (95% CI 3.68-4.24) points on the PrePSS score scale (range 0-10) with mean PrePSS scores of 3.73 and 7.70 in control and intervention group, respectively. Substantial improvement was seen in all subcategories of the PrePSS score with the highest absolute gains in the availability of stand-by antibiotics. We graded the degree of participation by the general practitioner (no contact, short contact, full intervention) and noted that the observed effect was only marginally influenced by the degree of physician participation. CONCLUSIONS Patients who had received the intervention exhibited a significantly higher adherence to guideline-based preventive measures compared to the control group. These data suggest that widespread adoption of this pragmatic intervention may improve management of asplenic patients. Health insurance provider-initiated identification of at-risk patients combined with a patient-focused intervention may serve as a blueprint for a wide range of other preventive efforts leading to patient empowerment and ultimately to better adherence to standards of care.

Abstract
INTRODUCTION Alterations in the endothelium and endothelial adhesion proteins such as von Willebrand factor (vWF) play major roles in hypercoagulability in thalassemia. vWF protein release leads to platelet aggregation and thrombi formation at the site of vascular injury. It is then degraded by the proteolytic enzyme ADAMTS13. Thrombospondin-1 is a multifactorial glycoprotein, which was reported to compete with ADAMTS13 for sites of vWF proteolysis. In this study, levels of vWF, ADAMTS13, and TSP-1 proteins were determined in β-thalassemia major patients. A possible association between TSP-1 and vWF and ADAMTS-13 was also evaluated. METHODS The study was conducted on 80 β-thalassemia major patients and 80 age and sex matched healthy controls. The 80 patients were sub-divided into two groups; splenectomised and non-splenectomised. vWF, ADAMTS13 and TSP-1 plasma level were measured using ELISA technique. RESULTS There was no significant difference in vWF and TSP-1 levels between patients and controls (p > 0.05). However, ADAMTS13 levels and ADAMTS13 activity/vWF antigen ratio were significantly higher in patients compared to controls (p < 0.05). VWF antigen and TSP-1 level were significantly higher in splenectomised patients (p = 0.025 and p < 0.001, respectively). We also observed a significant decrease in ADAMTS13 activity/vWF antigen ratio among splenectomised compared to non- splenectomised patients (p = 0.019). Correlation analysis showed a significant negative correlation between TSP-1 and vWF Collagen Binding Activity (r = -0.394, p = 0.021) and a positive correlation with ADAMTS13 activity/vWF antigen ratio (r = 0.356, p = 0.039) in splenectomised compared to non- splenectomised patients. CONCLUSION Our findings highlight the adequacy of patient management protocols for β-TM in Kuwait as patients presented with comparable levels of platelets, vWF and TSP-1 compared to normal controls. The reported increase in ADAMTS13 in patients may be required to maintain normal levels of vWF. Although no active thrombotic episodes were reported at the time of the study, the significant rise in platelets, vWF:Ag and TSP-1 levels in splenectomised patients may indicate a tendency towards hypercoagulability. Monitoring of splenectomised patients is recommended.

Abstract
Thalassemia is a major public health concern in India. The thalassemic burden in India is high, with an estimated 100,000 patients diagnosed with β-thalassemia syndrome. However, the exact number is unknown because of the absence of National Registries for patients. India alone contributes to approximately 25% of the global β-thalassemia burden. A possible option to control this burden is to endorse education and awareness programs, compulsory prenatal screening, and develop suitable facilities for genetic counseling, and availability of cost-effective diagnostic tests in India, especially in rural areas. In addition to the various clinical complications associated with thalassemia, lifelong intervention creates mental and physical trauma in patients and their relatives. Government and nongovernment organizations have initiated screening programs to prevent thalassemia. However, prenatal screening is not mandatory, and the reachability of screening programs in rural areas is yet to begin. This review article will discuss the progress in thalassemia research in India, including its prevalence, spectrum of β-thalassemia mutations, preventive and therapeutic measures, and awareness programs. More importantly, we will discuss the need and roadmap to strengthen prevention programs in India.

Abstract
Introduction The recent discovery of TAK981(Subasumstat), the first-in-class selective inhibitor of SUMOylation, enables new immune treatments. TAK981 is already in clinical trials to potentiate immunotherapy in metastatic tumors and hematologic malignancies. Cancer patients have more than ten times higher risk of infections, but the effects of TAK981 in sepsis are unknown and previous studies on SUMO in infections are conflicting. Methods We used TAK981 in two sepsis models; polymicrobial peritonitis (CLP) and LPS endotoxemia. Splenectomy was done in both models to study the role of spleen. Western blotting of SUMO-conjugated proteins in spleen lysates was done. Global SUMO1 and SUMO3 knockout mice were used to study the specific SUMO regulation of inflammation in LPS endotoxemia. Splenocytes adoptive transfer was done from SUMO knockouts to wild type mice to study the role of spleen SUMOylation in experimental sepsis. Results and discussion Here, we report that inhibition of SUMOylation with TAK981 improved survival in mild polymicrobial peritonitis by enhancing innate immune responses and peritoneal bacterial clearance. Thus, we focused on the effects of TAK981 on the immune responses to bacterial endotoxin, showing that TAK981 enhanced early TNFα production but did not affect the resolution of inflammation. Splenectomy decreased serum TNFα levels by nearly 60% and TAK981-induced TNFα responses. In the spleen, endotoxemia induced a distinct temporal and substrate specificity for SUMO1 and SUMO2/3, and both were inhibited by TAK981. Global genetic depletion of SUMO1, but not SUMO3, enhanced TNFα production and metabolic acidosis. The transfer of SUMO1-null, but not wild-type, splenocytes into splenectomized wild-type mice exacerbated TNFα production and metabolic acidosis in endotoxemia. Conclusion These results suggest that specific regulation of splenic SUMO1 can modulate immune and metabolic responses to bacterial infection.

Abstract
Post-splenectomy patients are at increased risk of infection. This complication is called overwhelming post-splenectomy infection (OPSI), which is uncommon but has high mortality. We describe a case of a man in his 80s who presented with septic shock with purpura fulminans caused by pyelonephritis. He had undergone a splenectomy in his 50s and had been taking prednisolone for the past six months for suspected immunoglobulin G4 (IgG4)-related disease. He was admitted to the intensive care unit but died the day after admission. OPSI is generally caused by encapsulated bacteria. However, in the present case, the causative agent was Escherichia coli, a bacterium that typically causes urinary tract infections. Post-splenectomy patients are known to have compromised bacterial clearance, and accumulation of bacteria such as E. coli can induce acute sepsis after splenectomy. Thus, physicians must have a high index of suspicion when treating splenectomy patients for the possibility that they may rapidly deteriorate to severe conditions such as OPSI, and the patients must be informed about the risk of severe infections, which can be fatal.

Abstract
Context Gaucher's disease (GD) is a rare inherited metabolic disorder caused by the defective activity of glucocerebrosidase. Enzyme replacement therapy (ERT) and substrate reduction therapy are the treatment of choice. Total splenectomy has a role when the child develops complications of massive splenomegaly. There are only a few case series of partial splenectomy in GD in the pediatric age group. Aims To study the role, technical feasibility, and challenges of partial splenectomy in children with GD with hypersplenism. Materials and Methods Retrospective review of children of GD who had partial splenectomy between February 2016 and April 2018. Demographics, clinical findings, laboratory, operative details, transfusion requirements, and perioperative, immediate, and late complications were retrieved. Clinical courses after discharge were obtained from follow-up data. Results Eight children with GD underwent partial splenectomy between 2016 and 2018. The median age at surgery was 3 years and 6 months (range -2 years to 8 years). Five children underwent partial splenectomy successfully, of which one child required postoperative ventilatory support for 48 h owing to lung atelectasis. Three children underwent completion splenectomy due to bleed from the cut surface of the splenic remnant. One of the children who underwent completion splenectomy expired on the postoperative day 5 due to refractory shock with multi-organ dysfunction. Conclusion Partial splenectomy has a definite role in selected children who present with massive splenomegaly with mechanical effects and/or hypersplenism while awaiting ERT.

Abstract
This report describes a case of cochlear implantation to treat profound deafness three months after a diagnosis of bacterial meningitis in a patient with a remote history of splenectomy. A 71-year-old woman with a remote history of a splenectomy over 20 years before presented with bilateral profound deafness that occurred as sequela from pneumococcal meningitis three months prior. The patient had been vaccinated against the 23-valent polysaccharide pneumococcal vaccine (PPV-23). The audiometric evaluation revealed no response in either ear. Imaging was suggestive of complete ossification of the right cochlea with partial ossification of the basal turn of the left cochlea. She underwent successful left-sided cochlear implantation. Standard post-implantation speech outcomes include consonant-nucleus-consonant (CNC) word and phoneme scores and Az-Bio in quiet and noise. The patient noted subjective improvement in her hearing. Performance measures markedly improved when compared to her pre-operative evaluation, which showed no aided sound detection. This case report highlights the possibility of meningitis many years after splenectomy that can result in profound deafness with labyrinthitis ossificans and the potential for hearing rehabilitation for cochlear implantation.

Abstract
OBJECTIVE To justify organ-preserving variants of total pancreatectomy. MATERIAL AND METHODS We retrospectively analyzed the results of classic and modified total pancreatectomy between September 2010 and March 2021. Implementing pylorus-sparing total pancreatectomy with preservation of stomach, spleen, gastric and splenic vessels, we thoroughly analyzed exocrine/endocrine disorders after total pancreatectomy and changes in immune status after splenectomy. Serum C-reactive protein and ferritin were assessed in 1, 3, 5, 7, 14 and 30 days after surgery in both groups. We also estimated daily glycemic profile after total pancreatectomy in classical and organ-preserving modifications. RESULTS We performed 37 total pancreatectomies including 12 pylorus-preserving total pancreatectomies with preservation of stomach, spleen, gastric and splenic vessels. General and specific postoperative complication rate was significantly lower after modified surgery compared to classic total pancreatectomy with gastric resection and splenectomy. CONCLUSION Modified total pancreatectomy is preferable for low-grade pancreatic tumors.

Abstract
INTRODUCTION Pancreatic surgery expands the indications and the use of total pancreatectomy. Considering a rather high rate of postoperative complications, the search for the ways to improve its outcomes is extremely relevant. The purpose of this study is justification and implementation of organ-preserving variants of total pancreatectomy. MATERIAL AND METHODS Retrospective analysis of treatment results after classic and modified total pancreatectomy in the surgical clinic of Botkin Hospital was performed from September 2010 to March 2021. During the development and implementation of pylorus-preserving total pancreatectomy with preservation of the stomach, spleen, gastric and splenic vessels, we thoroughly analyzed aspects of exocrine/endocrine disorders and changes of the immune status after performing the modified technique. RESULTS We performed 37 total pancreatectomies, including 12 pylorus-preserving total pancreatectomies with preservation of the stomach, spleen, gastric, and splenic vessels. General and specific postoperative complication rate in patients after the modified operation was significantly lower compared to the results of classic total pancreatectomy with gastric resection and splenectomy. CONCLUSION Modified total pancreatectomy is a method of choice for pancreatic tumors of low malignant potential.

Abstract
This is the second part of the thalassaemia update series which focuses on the dental journey of thalassaemia patients and the challenges encountered. This paper is a guide for recently qualified dentists who may not be experienced in the clinical implications of thalassaemia. A patient focus group was carried out with the UK Thalassaemia Society (UKTS) using a semi-structured interview format. All participants suffered from beta-major thalassaemia. The interview was conducted at the UKTS head office in London, UK. Participants consented for this interview and written consent forms were reviewed and completed by the author. The objectives were to: 1) review feedback from thalassaemia patients on the quality of dental care they receive in primary dental services; 2) evaluate the influence of social media in the thalassaemia community and how this has affected the self-confidence of thalassaemia patients; and 3) identify protocols that can be implemented for the primary care management and criteria for secondary care referral of thalassaemia patients.

Abstract
Sickle cell disease (SCD) is caused by a point mutation in the beta-globin gene. SCD is characterized by chronic hemolytic anemia, vaso-occlusive events leading to tissue ischemia, and progressive organ failure. Chronic inflammatory state is part of the pathophysiology of SCD. Patients with SCD have extremely variable phenotypes, from mild disease to severe complications including early age death. The spleen is commonly injured in SCD. Early splenic dysfunction and progressive spleen atrophy are common. Splenomegaly and hypersplenism can also occur with the loss of the crucial splenic function. Acute, life-threatening spleen-related complications in SCD are well studied. The association of laboratory parameters with the spleen status including hyposplenism, asplenia, and splenomegaly/hypersplenism, and their implication in vaso-occlusive crisis and long-term complications in SCD remain to be determined. We evaluated the association between the spleen status with clinical and laboratory parameters in 31 SCD patients: Group a) Patients with asplenia/hyposplenism (N = 22) (including auto-splenectomy and splenectomized patients) vs. Group b) patients with splenomegaly and or hypersplenism (N = 9). Laboratory studies included: Complete Blood Count, reticulocyte count, iron metabolism parameters, C Reactive Protein (CRP), Hb variant distribution, and D-dimer. Metabolic and morphological red blood cell (RBC) studies included: density gradient (by Percoll), glucose consumption, lactate release, and K+ leakage, fetal RBC (F-Cells) and F-Reticulocytes, annexinV+, CD71+, oxidative stress measured by GSH presence in RBC and finally Howell Jolly Bodies count were all analyzed by Flow Cytometry. Scanning electron microscopy analysis of RBC was also performed. Patients with asplenia/hyposplenism showed significantly higher WBC, platelet, Hematocrit, hemoglobin S, CRP, D-dimer, Gamma Glutamyl Transferase (GGT), cholesterol, transferrin, annexin V+ RBCs, CD71+ RBCs, together with a markedly lower F Reticulocyte levels in comparison with splenomegaly/hypersplenism patients. In summary, important differences were also found between the groups in the studied RBCs parameters. Further studies are required to elucidate the effect of the spleen including hyper and hypo-splenia on laboratory parameters and in clinical manifestations, vascular pathology, and long-term complications of SCD. The benefits and risks of splenectomy compared to chronic transfusion need to be evaluated in clinical trials and the standard approach managing hypersplenism in SCD patients should be re-evaluated.

Abstract
Congenital asplenia is a rare disorder commonly associated with other visceral and cardiac congenital anomalies. Isolated congenital asplenia is even less common than syndromic forms. The risk of severe bacterial infections associated with asplenia is the most concerning clinical implication and carries a significant mortality risk. Prophylactic measures against the clinical syndrome known as overwhelming postsplenectomy infections (OPSI) include vaccination, prophylactic and emergency antibiotics and health education including fever management and travel advice. This case series describes fourteen adults with congenital asplenia and polysplenia syndrome, most of whom were diagnosed incidentally as adults, and outlines the nature of their diagnosis, clinical phenotype, family history and key pathology findings.

Abstract
INTRODUCTION : Streptococcus pneumoniae is the most frequent cause of overwhelming post-splenectomy infections. Pneumococcal vaccination is generally recommended for splenectomized individuals. However, most of our knowledge comes from a few observational studies or small randomized clinical trials. We conducted this systematic review to assess the evidence of efficacy, antibody response, and the best timing for pneumococcal vaccination in splenectomized individuals. AREAS COVERED : The systematic review was conducted according to the PRISMA guidelines. We screened 489 articles, included 21 articles, and assessed the risk of bias using Cochrane RoB 2 and ROBINS-I. We summarized the findings narratively due to the heterogeneity of the studies. EXPERT OPINION Splenectomized individuals seem to have adequate antibody responses to pneumococcal vaccines. No differences in antibody responses were observed compared to healthy controls, except in one study. The studies were heterogeneous, and the majority had moderate to high degree of bias. There is a lack of clinical evidence for efficacy and best timing of pneumococcal vaccination in splenectomized individuals. Randomized clinical trials addressing these issues are needed.

Abstract
The spleen is a secondary lymphoid organ that belongs to the reticular-endothelial system, directly connected to blood circulation. The spleen is greatly involved in the immune response, especially against capsulated bacteria. Splenectomy plays a fundamental role in the treatment of numerous pediatric hematologic disorders. Taking into account all the possible complications (especially infections) linked to this procedure, alternatives to total splenectomy have been sought. Partial splenectomy has been proposed as a treatment that allows the reduction of infectious risk. This approach has proven safe and feasible in most patients, but multicentric and prospective studies are necessary to more accurately define the indications for performing partial splenectomy. However, vaccinations and antibiotic prophylaxis remain fundamental for preventing serious infections, even in the case of partial splenectomy. We review anatomical and functional properties of the spleen, with a focus on medical or surgical indications to splenectomy, aiming to give practical educational information to patients and their families after splenectomy. Furthermore, we discuss the feasibility of partial splenectomy in children with hematologic diseases who require splenectomy.

Abstract
Aim The spleen plays an important role in the immune response, and patients with impaired spleen function are at risk of overwhelming post‐splenectomy infection. This study investigated whether the spleen volume could predict the prognosis of patients with bacteremia caused by encapsulated organisms. Methods This was a single‐center, retrospective observational study at Tokyo Medical University Hospital. Twenty patients with encapsulated bacteria (Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, and Capnocytophaga canimorsus) detected in blood culture between January 2017 and July 2020 were included in the study and categorized into two groups: survive and nonsurvive groups. We investigated the association between spleen volume (SV), spleen volume index (SVI), and in‐hospital mortality. The SVI was defined as: SVI‐H, spleen volume cm3/height m; SVI‐BW, spleen volume cm3/body weight kg; and SVI‐A, spleen volume cm3 × age/100. Results The number of patients in the survive group was 17, and that of the non‐survive group was 3. The SV and SVI were smaller in the nonsurvive group than in the survive group (P < 0.05). The calculated the SV cut‐off for the prediction of prognosis was 36 cm3 with a sensitivity of 94.1% and specificity of 66.7% with a positive predictive value of 94.1% and a negative predictive value of 66.7%. Conclusions The SV and SVI could be used to predict the prognosis of bacteremia caused by encapsulated organisms. If the spleen volume as measured by computed tomography is small, more intensive treatment should be considered.

Abstract
Babesiosis is attracting increasing attention as a worldwide emerging zoonosis. The first case of human babesiosis in Europe was described in the late 1950s and since then more than 60 cases have been reported in Europe. While the disease is relatively rare in Europe, it is significant because the majority of cases present as life-threatening fulminant infections, mainly in immunocompromised patients. Although appearing clinically similar to human babesiosis elsewhere, particularly in the USA, most European forms of the disease are distinct entities, especially concerning epidemiology, human susceptibility to infection and clinical management. This paper describes the history of the disease and reviews all published cases that have occurred in Europe with regard to the identity and genetic characteristics of the etiological agents, pathogenesis, aspects of epidemiology including the eco-epidemiology of the vectors, the clinical courses of infection, diagnostic tools and clinical management and treatment.

Abstract
The spleen is a commonly injured organ in blunt abdominal trauma. Splenic preservation, however, is important for immune function and prevention of overwhelming infection from encapsulated organisms. Splenic artery embolization (SAE) for high-grade splenic injury has, therefore, increasingly become an important component of non-operative management (NOM). SAE decreases the blood pressure to the spleen to allow healing, but preserves splenic perfusion via robust collateral pathways. SAE can be performed proximally in the main splenic artery, more distally in specific injured branches, or a combination of both proximal and distal embolization. No definitive evidence from available data supports benefits of one strategy over the other. Particles, coils and vascular plugs are the major embolic agents used. Incorporation of SAE in the management of blunt splenic trauma has significantly improved success rates of NOM and spleen salvage. Failure rates generally increase with higher injury severity grades; however, current management results in overall spleen salvage rates of over 85%. Complication rates are low, and primarily consist of rebleeding, parenchymal infarction or abscess. Splenic immune function is felt to be preserved after embolization with no guidelines for prophylactic vaccination against encapsulated bacteria; however, a complete understanding of post-embolization immune changes remains an area in need of further investigation. This review describes the history of SAE from its inception to its current role and indications in the management of splenic trauma. The endovascular approach, technical details, and outcomes are described with relevant examples. SAE is has become an important part of a multidisciplinary strategy for management of complex trauma patients.

Abstract
There are numerous advantages of splenic vessel preservation in performing the minimally invasive spleen preserving distal pancreatectomy. Dissection along the splenic artery, and a medial to lateral dissection of the splenic vein, is associated with high risk of injury and bleeding. Proximal control of the splenic artery with vessel loops, which require tightening or adjustment with the advent of distal bleeding, is inefficient. Instead, a modified technique (the Royal North Shore Technique), whereby a vascular clamp is placed on the splenic artery, reduces splenic artery inflow and indirectly, splenic vein returns. This allows for more accurate and injury-free dissection of the now non-distended splenic vein and the associated tributaries, and maintains a relatively bloodless field in the event of arterial injury.

Abstract
Background: When oncologically feasible, avoiding unnecessary splenectomies prevents patients who are undergoing distal pancreatectomy (DP) from facing significant thromboembolic and infective risks. Methods: A systematic search of MEDLINE, Embase, and Web Of Science identified 11 studies reporting outcomes of 323 patients undergoing intended spleen-preserving minimally invasive robotic DP (SP-RADP) and 362 laparoscopic DP (SP-LADP) in order to compare the spleen preservation rates of the two techniques. The risk of bias was evaluated according to the Newcastle–Ottawa Scale. Results: SP-RADP showed superior results over the laparoscopic approach, with an inferior spleen preservation failure risk difference (RD) of 0.24 (95% CI 0.15, 0.33), reduced open conversion rate (RD of −0.05 (95% CI −0.09, −0.01)), reduced blood loss (mean difference of −138 mL (95% CI −205, −71)), and mean difference in hospital length of stay of −1.5 days (95% CI −2.8, −0.2), with similar operative time, clinically relevant postoperative pancreatic fistula (ISGPS grade B/C), and Clavien–Dindo grade ≥3 postoperative complications. Conclusion: Both SP-RADP and SP-LADP proved to be safe and effective procedures, with minimal perioperative mortality and low postoperative morbidity. The robotic approach proved to be superior to the laparoscopic approach in terms of spleen preservation rate, intraoperative blood loss, and hospital length of stay.

Abstract
The spleen is the most commonly injured organ in blunt abdominal trauma. Patients who are hemodynamically unstable due to splenic trauma undergo definitive operative management. Interventional radiology plays an important role in the multidisciplinary management of the hemodynamically stable trauma patient with splenic injury. Hemodynamically stable patients selected for nonoperative management have improved clinical outcomes when splenic artery embolization is utilized. The purpose of this article is to review the indications, technical aspects, and clinical outcomes of splenic artery embolization for patients with high-grade splenic injuries.

Abstract
RATIONALE The aim of this study was to analyze the metabolomics of lung with different host inflammation of acute respiratory distress syndrome (ARDS) for the identification of biomarkers for predicting severity under different inflammatory conditions. METHODS Cecal ligation and puncture (CLP) and lipopolysaccharide (LPS)-intratracheal injection induced acute lung injury (ALI) were used. A mouse model was used to explore lung metabolomic biomarkers in ALI/ARDS. The splenectomy model was used as an auxiliary method to distinguish between hyper- and hypo-inflammatory subtypes. Plasma, lung tissue and bronchoalveolar lavage fluid (BALF) samples were collected from mice after CLP/LPS. The severity of lung injury was evaluated. Expression of tumor necrosis factor-α (TNF-α) in mice serum and lung was tested by enzyme-linked immunosorbent assay (ELISA) and polymer chain reaction (PCR). Polymorphonuclear cells in BALF were counted. The lung metabolites were detected by gas chromatography/mass spectrometry (GC/MS), and the metabolic pathways predicted using the KEGG database. RESULTS The LPS/CLP-Splen group had more severe lung injury than the corresponding ALI group; that in the CLP-Splen group was more serious than in the LPS-Splen group. TNF-α expression was significantly elevated in the serum and lung tissue after LPS or CLP, and higher in the LPS/CLP-Splen group than in the corresponding ALI group. The level of TNF-α in the CLP-Splen group was elevated significantly over that in the LPS-Splen group. Both these groups also showed significant neutrophil exudation within the lungs. During differential inflammation, more differential metabolites were detected in the lungs of the CLP group ALI mice than in the LPS group. A total of 41 compounds were detected in the lungs of the CLP and CLP-Splen groups. Contrastingly, eight compounds were detected in the lungs of the LPS and LPS-Splen groups. The LPS-Splen and CLP-Splen groups had significant neutrophil exudation in the lung. Random forest analysis of lung-targeted metabolomics data indicated 4-hydroxyphenylacetic acid, 1-aminocyclopentanecarboxylic acid (ACPC), cis-aconitic acid, and hydroxybenzoic acid as strong predictors of the hyper-inflammatory subgroup in the CLP group. Furthermore, with splenectomy, 13 differential metabolic pathways between the CLP and LPS groups were revealed. CONCLUSIONS Hyper-inflammatory subgroups of ARDS have a greater inflammatory response and a more active lung metabolism. Combined with the host inflammation background, biomarkers from metabolomics could help evaluate the response severity of ARDS.

Abstract
COVID-19 has led to disruption in routine immunization programs around the globe and here in Canada. The National Advisory Committee on Immunization (NACI) in Canada has indicated that this sets the stage for serious outbreaks of vaccine-preventable diseases. The World Health Organization has evidence-based guidance on how to address missed opportunities for vaccination, albeit predominately applicable for low- and middle-income countries. In Canada, immunization applies beyond infant and childhood immunization, with immunization across the life course being recommended by NACI. Three components stand out and must be integrated and used concurrently for best effect on catch-up in Canada: (1) Identify who has been missed across the life course; (2) detect delivery gaps, adapt and adjust, and develop multipronged tailored strategies for catch-up; and (3) communicate, document, evaluate and readjust the immunization programs. All must be adapted to the reality of the evolving COVID-19 pandemic. We cannot go back to a pre-COVID-19 world. However, ensuring that routine immunization and catch-up programs are done well during this pandemic strengthens the immunization foundation in Canada for when COVID-19 vaccines become available.

Abstract
Background Liver cirrhosis occurs in approximately 80–90% of patients with hepatocellular carcinoma (HCC), and hepatic resection may be dangerous because of well-documented liver cirrhosis, which may be accompanied by portal hypertension (PH). Here we report a patient with advanced HCC with gastric varices and PH who experienced a good clinical course after undergoing balloon-occluded retrograde transvenous obliteration (BRTO), percutaneous transhepatic portal vein embolization (PTPE), hand-assisted laparoscopic (HALS) splenectomy, and right lobectomy of the liver. Case presentation A 72-year-old man had two HCCs with gastric varices. CT revealed one tumor (4.5 cm) located in segment 7, involving the right hepatic vein, adjacent to the middle hepatic vein. Another tumor (2.7 cm) was located in segment 6. He first underwent BRTO for gastric varices and PTPE for planned right lobectomy of the liver. To reduce PH, HALS splenectomy was performed, and uncomplicated right lobectomy of the liver was performed 10 weeks after the first visit. He has remained free of recurrence for at least 1 year. Conclusions Our patient underwent uncomplicated BRTO, PTPE, HALS splenectomy, and right lobectomy of the liver for advanced HCC with PH. Controlling portal pressure is important when hepatic resection is required to treat HCC with PH.

Abstract
BACKGROUND Splenic vein stenosis and occlusion, which are known causes of left-sided portal hypertension, often occur secondary to trauma, pancreatitis, or invasion or compression by pancreatic tumors. However, few reports have described idiopathic splenic vein stenosis. CASE PRESENTATION A 70-year-old man was referred to our hospital for examination of isolated gastric varices. He had no history of liver disease, pancreatitis, or abdominal trauma. Computed tomography revealed stenosis of almost the entire length of the splenic vein, and development of gastric fundal and short gastric varices. No inflammatory changes or neoplastic lesions of the pancreas were observed in any imaging study. The patient was diagnosed with left-sided portal hypertension caused by idiopathic splenic vein stenosis, and splenectomy was performed. The postoperative course was smooth, and improvement of the gastric varices was shown by upper gastrointestinal endoscopy at 3 months after the operation. CONCLUSIONS Idiopathic splenic vein stenosis is an extremely rare cause of left-sided portal hypertension. Splenectomy is one of the most effective treatments for left-sided portal hypertension caused by idiopathic splenic vein stenosis.
