Viral hepatitis A in children: a false prosperity?

The article presents current data on the state of the issue of Hepatitis A (HA) in children in the Russian Federation and describes clinical and epidemiologic features of rare cases of severe course of the disease, as well as pathogenetic mechanisms of liver damage mediated by cell immune response. Objective. To identify clinical and epidemiologic features of the modern course of HA and its outcomes in children of Saint Petersburg within the period of 2018— 2023. Materials and methods. The study included 89 children diagnosed with HA, undergoing treatment at the Children's Research and Clinical Center for Infectious Diseases from 2018 to 2023. The analysis of disease progression in this group of patients was presented using clinical-anamnestic, epidemiologic, biochemical, virologic and instrumental data. Results. The analysis of infection sources showed a high frequency of HA infection within the family (44.9 ± 0.8%) and significantly less in childcare facilities and schools (7.9 ± 1.0%). The frequency of children with unidentified sources of infection remained high (47.2 ± 0.7%). One-third of all disease cases were imported from southern regions. Most hospitalized children had icteric HA (64.0 ± 0.6%) of moderate severity (79.8 ± 0.5%). Severe HA was observed in 6 patients (6.7 ± 1.0%). During the study, 17 patients (19.1 ± 0.9%) had a prolonged, complicated course of the disease, including ascites and aplastic anemia (12.6 ± 2.2%). Ascites was found in 4 patients with severe severity and in 5 patients with moderate severity of HA. Conclusions. Currently, there is an upward trend in the incidence of HA in the Russian Federation and Saint Petersburg, especially among schoolchildren (56.2%). A rather high frequency of severe (6.7%) and complicated forms (19.1%) of the disease is observed, and the growth of ascites and aplastic anemia cases in HA draws particular attention.

Abstract 4134777: Predictive Factors for Early Recovery from Mechanical Circulatory Support in Patients with Fulminant Myocarditis

Background: Fulminant myocarditis (FM) requiring veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is fatal and has a complicated clinical course. In such FM cases, predicting which cases are likely to achieve early recovery is crucial for developing acute-phase treatment strategies. We aimed to examine the factors predicting early recovery in fatal cases of FM requiring VA-ECMO using multicenter cohort of patients with myocarditis. Methods: We retrospectively analysed 343 patients with FM requiring VA-ECMO between April 2012 and March 2017. The early recovery group was defined as patients who were successfully weaned off mechanical circulatory support (MCS) within 7 days from MCS deployment and discharged with favorable outcomes. We divided patients into early recovery group and non-early recovery group. Predictors of early recovery were investigated by performing a multivariate analysis, including significant variables ( p <0.05) identified from a univariate analysis of baseline clinical parameters and meaningful variables from previous reports. Results: Among the eligible patients, 71 were assigned to the early recovery group, whereas 272 were assigned to the non-early recovery group. The baseline patient demographics showed the early recovery group was significantly younger (45 [30-63] years vs. 56.5 [40-67] years, p =0.003), had higher WBC counts (11,400 [8,500-16,000] /μL vs. 9,900 [7,162.5-13,297.5] /μL, p =0.009), and had lower CK-MB levels (38.5 [18.0-75.3] U/L vs. 73.0 [42.5-137.0] U/L, p <0.001), than the non-early recovery group. In the histological diagnosis, the proportions of lymphocytic and eosinophilic myocarditis were similar between the two groups, whereas the proportions of giant cell myocarditis tended to be higher in the non-early recovery group. Multivariate analysis showed the independent predictors of early recovery were age ≤40 years (OR: 3.25; 95% CI: 1.42-7.44), WBC ≥ 11,000 /μL (OR: 3.10; 95% CI: 1.39-6.86) and CK-MB ≤ 61 U/L (OR: 2.46; 95% CI: 1.06-5.72), and if all conditions were fulfilled, the early recovery rate increased to 61.5%. Conclusions: Early recovery group had higher inflammatory parameter levels but lower myocardial damage marker levels on admission in addition to age ≤40 years, suggesting that patients having a strong acute-phase inflammatory response with a lower degree of myocardial damage, could recover earlier.

Marine-Derived Therapeutics for the Management of Glioblastoma: A Case Series and Comprehensive Review of the Literature

Introduction: Glioblastoma is a fatal intracranial neoplasm that is refractory to treatment, with inevitable disease recurrence and progression to death. Marine-derived compounds, including those found in nutraceutical products, may provide therapeutic benefit in the setting of glioblastoma. We present two patient cases whose courses demonstrate a compelling role for marine-derived products in the management of glioblastoma. Cases: Case 1 describes a patient with MGMT promoter unmethylated glioblastoma who went on to complete standard of care chemoradiation along with concurrent use of a majority sea cucumber (MSC) blend known as SeaCare® (SeaCare, Torrington, CT, USA). Her survival of over 2 years significantly exceeds the recognized median survival time of glioblastoma. Case 2 describes a patient with a complicated course who experienced dramatic improvement after the initiation of the MSC blend, with an exceptional survival time of over 4 years post-diagnosis. Discussion: The mechanisms of marine-derived products that underlie these dramatic clinical effects are likely multifaceted but may hinge on the modification of the tumor immune microenvironment and suppression of tumorigenic effects. Specifically, the change in tumor-associated macrophages (TAMs) within the tumor microenvironment is central to this complex interplay. Conclusions: Ultimately, the use of marine products in the treatment of glioblastoma may present a novel and promising therapeutic strategy that warrants further investigation.

Review article: Measuring disease severity in inflammatory bowel disease - Beyond treat to target.

Inflammatory bowel disease (IBD) follows a heterogenous disease course and predicting a patient's prognosis is challenging. There is a wide burden of illness in IBD and existing tools measure disease activity at a snapshot in time. Comprehensive assessment of IBD severity should incorporate disease activity, prognosis, and the impacts of disease on a patient. This review investigates the concept of disease severity in adults with IBD to highlight key components contributing to this. To perform this narrative review, a Medline search was conducted for full-text articles available at 1st March 2024 using search terms which encompassed disease activity assessment, disease severity, prognosis, natural history of Crohn's disease (CD) and ulcerative colitis (UC), and the burden of IBD. Current methods of disease assessment in IBD have evolved from a focus on the burden of symptoms to one that includes inflammatory targets, genetic, serological, and proteomic profiles, and assessments of quality-of-life (QoL), disability, and psychosocial health. Longitudinal studies of IBD suggest that the burden of illness is driven by disease phenotype, clinical markers of complicated disease course (previous intestinal resection, corticosteroid use, perianal disease in CD, recent hospitalisations in UC), gut inflammation, and the impact of IBD on the patient. Disease severity in IBD can be difficult to conceptualise due to the multitude of factors that contribute to IBD outcomes. Measurement of IBD severity may better encapsulate the full burden of illness rather than gut inflammation alone at a single timepoint and may be associated with longitudinal outcomes.

Оцінка інформативності клініко-інструментальних та лабораторних показників у виявленні активності патогенетичних факторів, асоційованих зі змінами перебігу інфаркту міокарда в період воєнного стану

The aim – to establish markers of clinical and functional state development in patients with acute myocardial infarction inherent in wartime.Materials and methods. A cohort of 133 STEMI patients was examined (77.4 % men, 61.7±0.9 years). Part of the patients (group 1) was hospitalized from February to May 2019 (n=87), while the other part of them (group 2) was hospitalized in the period from February 24, 2022 to May 2023 (n=46) within the first 24 hours from the development of symptoms (average time of admission 5.2±0.4 hours). In order to eliminate discrepancies in indicators, which with a low probability are related to the action of wartime factors, comparable samples were made from groups 1 and 2 (52 patients and 17 patients, respectively). Comparison of groups was carried out based on clinical and anamnestic and laboratory parameters of the first day.Results and discussion. At the admission to the hospital, markers of a specific clinical and functional state in patients with STEMI due to the influence of wartime factors are: level of leukocytes > 13.0 · 109/L, monocytes > 0.5 · 109/L, lymphocytes > 1.2 . 109/L, triglycerides > 1.63 mmol/L, heart rate > 76 beats/min, as well as criteria made up of these indicators (in particular, products of the level of monocytes or lymphocytes, the level of triglycerides and heart rate, as well as the 7-component scale, which takes into account heart rate, ESR, glucose and triglyceride levels, as well as the number of monocytes, lymphocytes and platelets). Moreover, the increase in the number of monocytes is not associated with hospital complications in these patients. Instead, the level of triglycerides, the number of lymphocytes and platelets are directly related both to the influence of wartime factors and to the complicated hospital course of STEMI.Conclusions. The influence of wartime factors in patients with STEMI is combined with the response to myocardial damage. It leads to an increase in the risk of a complicated course of the hospital stage, as well as to specific clinical and laboratory changes. These changes make it possible to recognize the impact of wartime factors and patients at high risk of hospital course of myocardial infarction.

Mortality and patient stratification 30 days after Staphylococcus aureus bacteraemia in patients with cardiac implantable electronic devices - a Danish nationwide cohort study

Abstract Background Staphylococcus aureus bacteraemia (SAB) is a high-risk condition with a reported 30-day mortality of up to 25% even with timely and correct treatment. Patients with cardiac implantable electronic devices (CIEDs) are at increased risk of a complicated course of disease due to the risk of device infection. Purpose We aimed to estimate the 30-day mortality rate following SAB among adult Danish patients with a de novo CIED. Furthermore, we aimed to identify patients with low, intermediate, and high mortality risk following SAB. Methods Using The National Danish Staphylococcus Aureus Bacteriemia Database and The Danish Pacemaker and ICD Register, we identified all Danish patients aged 18 to 99 years with a de novo CIED implantation between 2000 and 2020, and subsequently positive Staphylococcus aureus blood culture. The primary outcome was 30-day all-cause mortality from date of SAB. Clinical variables significantly associated with increased 30-day mortality following SAB were identified (p<0.05 and 95% CI not including 1) using adjusted multivariable Cox regression modelling. We tested variables related to age, sex, calendar year of SAB, device type, timing of infection, previous SAB, concomitant medication, and clinically relevant pre-existing co-morbidities including valvular replacement, recent surgery, and renal dialysis. Patients were awarded 1 point for each of the significant variables present, and the sum was used to stratify into low-, intermediate-, and high-risk groups. The cut-offs between the groups were set at 0 and 2 points (0 points = low risk, 1-2 points = intermediate risk, ≥3 = high risk). Results We identified 1,393 patients with de novo CIED (pacemaker: n=983, implantable cardioverter defibrillator: n=230, cardiac resynchronization therapy w/wo defibrillator capacity: n=180) and subsequent SAB (median time to SAB from CIED implantation: 679 days [IQR 168-1,525]). Median age at the time of SAB diagnosis was 77 years [IQR 68-84] with 72.4% being males. In total, 469 patients died within the first 30 days from SAB, equivalent to an overall 30-day mortality rate of 33.7% (95% CI 31.2-36.2). We identified high age, left sided valvular disease, use of systemic corticosteroids, and SAB occurring >6 months from CIED implantation to be associated with an increased hazard of 30-day mortality following the SAB diagnosis (Fig. 1). The median total sum obtained from the stratification model was 2 points [IQR 1-2]. 30-day all-cause mortality was estimated to 16.2%, 31.6% and 54.9% for the low-, intermediate- and high-risk groups, respectively (Fig. 2). Conclusions In patients with a de novo cardiac implantable electronic device and subsequent Staphylococcus aureus bacteraemia the overall 30-day mortality from date of SAB was 33.7%. Patients with high age, recent surgery, left sided valvular disease, and use of systemic corticosteroids were particularly at risk.Fig. 1.Simplified stratification modelFig. 2.30-day mortality following SAB

The 5-Item Modified Frailty Index (mFI-5) for risk stratification of patients with infective endocarditis undergoing cardiac surgery

Abstract Background population aging has led to an increased burden of frailty as an emerging global health issue, and variables for its quantification in patients with infective endocarditis (IE) are lacking in current surgical risks scores. The 5-item modified frailty index (mFI-5) score has shown to be effective in the prediction of surgical outcomes in other medical scenarios. Purpose this study aimed to assess the role of the mFI-5 in the prediction of surgical outcomes in patients with left-sided IE undergoing cardiac surgery. Methods a total of 112 cases of confirmed left-sided IE undergoing surgery, were consecutively collected and followed during one year after diagnosis in two tertiary hospitals between 2016 and 2021. The mFI-5 score included 5 baseline patient-specific comorbidities: diabetes, congestive heart failure, non-independent functional status (Barthel index <80), hypertension and chronic obstructive pulmonary disease (range 0-5), and patients were categorised as mFI-low (<2, n=65), and mFI-high (>=2, n=47). Results mean age was 66 [SD 15] years, 67% were men and community-acquired infections were 75%. As shown in Table 1, mFI-high patients were older and, aside from the specific comorbidities included in the score, with more chronic kidney disease. The most isolated pathogen was S. viridans (n=32), predominantly in mFI-low, in contrast to enterococcal and polymicrobial IEs, which were more frequent in mFI-high. Larger vegetations were reported in mFI-high [16 (10) vs 13 (9) mm, p 0.03], with no differences regarding infection site or periannular complications. Acute kidney injury, decompensated heart failure and higher natriuretic peptides were more common in mFI-high. Regarding mortality, in-hospital deaths were more frequent in mFI-high group. When analyzing mFI-score as a discrete variable, in-hospital mortality was associated with higher median scores values [2 (2) vs 1(1) points, p 0.02], being 2 points the optimal cutoff point for prediction [AUC 0.64 (95% CI 0.54-0.73), Fig.1A]. Among survivors who completed follow-up (n=82), rehospitalization and all-cause mortality rates in mFI-high exceeded those from mFI-low. Predictors of in-hospital and 1-year mortality were assessed by logistic regression (Fig. 1B), confirming the independent prognostic association of mFI-5-score in patients with IE undergoing surgery. Conclusions patients with IE undergoing cardiac surgery with higher mFI-5 scores were older, more predisposed to enterococcal and polymicrobial infections, and had a greater comorbidity burden with a more complicated clinical course. The mFI-score was independently associated with in-hospital mortality as well as rehospitalizations and 1-year mortality, positioning itself as an additional tool for risk stratification in this cluster of patients.Table 1Figure 1

The role and prognostic value of the interleukin 2 gene at multiple myeloma

Aim of the study. To determine the relationship of the polymorphic locus of the IL2 genetic marker (T-330G) with the risk of complicated course of multiple myeloma.Materials and methods. The molecular analysis of the IL2 (T-330G) gene was carried out in the laboratory of Molecular Genetics, cytogenetics and FISH at the Republican Specialized Scientific and Practical Medical Center of Hematology of the Republic of Uzbekistan (Tashkent city). 101 patients aged 34 to 72 years with a reliably established diagnosis of multiple myeloma were examined. IL2 polymorphism (T-330G) was genotyped by real-time PCR using primers from Litech (Russia) using an Applied Biosystems thermal cycler (USA).Results and discussion. An increased risk of complicated course of multiple myeloma compared with healthy individuals was found to be 1.6 times higher among carriers of the mutant G allele (χ2=4.3; p=0.05). Statistically significant differences between unfavorable loci in the group of patients with combined complications of multiple myeloma compared with the control were revealed.Conclusions. The risk of developing multiple myeloma compared with healthy individuals is 1.6 times higher among carriers of the mutant G allele (χ2=4.3; p=0.05) according to the polymorphism of the IL2 gene (T-330G). Along with this, a statistically significant relationship was established between unfavorable loci (G and G/G) with an increase of 2.5 (χ2=9.4; p=0.01) and 3.5 times (χ2=5.3; p=0.03) the risk of developing multiple myeloma complicated by plasmacytoma in combination with nephropathy.

Artificial intelligence systems for predicting disease outcomes in chronic ischemic heart disease patients who have undergone cardiac surgery in respect of anemic syndrome (review).

Materials and methods. The PubMed and RSCI databases were analyzed covering the period of 2000-2023. 906 articles were found using the keywords “artificial intelligence”, “anemia”, coronary artery disease”, “hemoglobin”, “cardiac surgery”, of which 38 met the criteria for inclusion in the analysis. Results. In a number of countries around the world, artificial intelligence (AI) systems have now been created to predict the course of IHD, however, at the moment, data have been published on the single system with AI elements, presented by the developers of the University of Turin (Italy). It has the functionality of predicting the course of IHD and complications of invasive procedures for IHD against the background of anemic syndrome, based on the use of the HAS-BLEED scale. The increase in the number of CABG operations determines the importance of further research into their long-term results and the development of programs for their management, which will take into account such factors that are important for choosing a strategy for their management and the possibility of influencing the risks of an unfavorable prognosis. This review presents published data on the developed and used digital products based on artificial intelligence intended for the management of patients with coronary artery disease, including taking into account basic hematological parameters. Conclusion. Analysis of existing developed AI systems showed a focus on solving prognostic issues. At the same time, in our opinion, the range of analyzed parameters is not wide enough, in particular, taking into account the presence of anemia, which plays one of the key roles in modifying the risk of adverse outcomes (coronary deaths, repeated acute coronary events, progression of CHF).

FUNCTIONAL STATE OF RENAL PARENCHYMA IN CHILDREN WITH DYSMETABOLIC NEPHROPATHY

Abstract. Metabolic nephropathy in children is a relevant issue in our time, as the prevalence of this disease is increasing. Negative consequences of metabolic nephropathy include a gradual deterioration of kidney function. A significant aspect is the fact that metabolic nephropathy can lead to the development of chronic kidney disease in children. Chronicity requires continuous medical monitoring and treatment to support kidney function and prevent further complications, such as renal insufficiency and other metabolic disorders. There is no doubt that one of the leading pathogenetic factors in kidney dysfunction is hypoxia. It can be caused by both hemodynamic disturbances associated with renal pathology and tissue respiration disorders in congenital dysplasia of the kidney's connective tissue, which arises in the embryo under the influence of epigenetic factors in utero and is further exacerbated by various epigenetic factors in postnatal life. Purpose of the work to investigate the functional state of kidney parenchyma in children with dysmetabolic nephropathy. Materials and methods. Two groups of children were examined: those with a complicated course of dysmetabolic nephropathy, a history of inflammatory episodes of the urinary system organs (Group I - UN, 52 children), and dysmetabolic nephropathy with persistent crystalluria (Group II - DN, 56 children). A control group consisted of 65 healthy children. Tubular reabsorption, as a partial function of the proximal segment of the nephrons, was assessed based on urinolysis test data, specifically the levels of excretion of inorganic phosphates, proteinuria, amino acids, reduced sugars (maltose, sucrose, fructose by Benedict's test), glucose (by Gaines's test), and calcium (by Sulcovitch's test). The level of creatinine and glycosaminoglycan (GAG) excretion in daily urine in children with dysmetabolic nephropathy was determined and compared with data from healthy children in the control group. Research results. In children from both observation groups, a significantly high frequency of hyperphosphaturia (94.23% and 96.42%), calciuria (94.23% and 89.28%), glucosuria (78.85% and 73.21%), increased excretion of amino acids in the urine (40.38% and 37.5%), microproteinuria (32.69% and 28.57%), and increased excretion of reduced sugars (28.85% and 26.79%) were observed. The daily excretion of creatinine, glycosaminoglycans, and oxypyrrolidine in the urine of children with dysmetabolic nephropathy indicates a significantly reduced level of creatinine in the daily urine in the majority of children in Group I (0.56±0.19 g/L, 80.77% of those examined) and more than half of the children in Group II (0.83±0.08 g/L, 57.14% of those examined), compared to the data from healthy children in the control group (1.25±0.75 g/L, 0.0%). Conclusions. The analysis of the functional state of the kidney tissue in oxalate dysmetabolic nephropathy in children allows us to testify to the presence of tubular and glomerular partial renal tissue failure. Significant decreases in creatinine excretion and increased excretion of glycosoaminoglycans in the urine and significantly higher levels of oxyproline in the urine indicate the presence of glomerular type partial renal failure in oxalate dysmetabolic nephropathy in children and the presence of undifferentiated dysplasia of the renal connective tissue with the onset of its sclerosis with subsequent transition to interstitial nephritis. The presence of these changes in the vast majority of children with complicated course of oxalate dysmetabolic nephropathy in the period of clinical and laboratory remission of the inflammatory process indicates the priority of renal connective tissue dysplasia and paucity of renal failure in the pathogenesis of dysmetabolic nephropathy and its severity in children. Indicators of oxyproline creatinine, glycosoaminoglycans and oxyproline excretion can be used as epigenetic markers of susceptibility to dysmetabolic nephropathy in general and its more severe course in particular. Keywords: dysmetabolic nephropathy, functional state, kidney parenchyma, nephron.

Emergency department visits and hospitalizations attributable to recent Epstein-Barr virus infection

Objective Infectious mononucleosis (IM) or mono is typically caused by primary infection with Epstein-Barr virus (EBV) and may have a months-long, complicated course. We utilized population-based data to add to the limited literature on health care utilization following EBV infection. Methods The Rochester Epidemiology Project includes medical records for ∼60% of residents living in 27 counties of Minnesota (MN) and Wisconsin (WI). Persons meeting a case definition of recent EBV infection from 1 January 1998 to 31 December 2021 were compared to three persons not meeting the definition, matched on case’s sex, age, and index date. Emergency department (ED) visits and hospitalizations in the two groups were compared during 5-years’ follow-up divided into three periods (short-term ≤3 months, mid-term >3 months–1 year, long-term >1–5 years). Adjusted hazard ratios (AHR) were estimated to account for the potential influence of confounding variables. Results In total, 6,423 persons had a recent EBV infection and were matched to 19,269 comparators. The risk of an ED visit was significantly higher among cases in the short-term period (24.3% vs referents: 7.6%, p <.001; AHR = 3.71, 95% CI = 3.41–4.03). Cases also had an increased risk of hospitalization in the short-term (5.2% vs 1.6%: referents, p <.001; AHR = 3.53, 95% CI = 2.94–4.24). For ED visits but not hospitalization, the excess risk persisted into the mid-term follow-up period. Persons without a concurrent clinical diagnosis of IM continued to have an increased risk of hospitalizations up to 1 year after index date (AHR = 1.45, 95% CI = 1.09–1.91) and an increased risk of ED visits up to 5 years after the index date (AHR = 1.29, 95% CI = 1.14–1.46). Conclusion There is a substantial short- and mid-term increased risk of serious health care encounters associated with recent EBV infection. Mid- and long-term risks are increased in patients who do not have a concomitant diagnosis of IM.

SURGICAL TREATMENT OF RECTAL CANCER WITH PRESERVATION OF THE LEFT COLIC ARTERY AND ICG NAVIGATION

Goal. To analyze the peculiarities of surgical diagnosis of lymphogenic metastasis in patients with colorectal cancer. Generalization of data from Ukrainian and foreign literature, results of randomized studies and meta-analyses. The study is based on the results of observation of 88 patients with colorectal cancer (CRC) of the prospective study group. To analyze the features of surgical diagnostics of lymphogenic metastasis in patients with colorectal cancer. Materials and methods. The results of surgical treatment of 88 patients with rectal cancer were analyzed and systematized. These patients underwent examination and treatment in 2023-2024 at the "Prykarpattian Clinical Oncology Center of the Ivano-Frankivsk Regional Council." The study included patients with stage II-III colorectal cancer (T2-3N0-2M0) without complicated courses. All patients received treatment based on NCCN recommendations. Surgical treatment was performed in standard volume with the removal of all regional lymph node groups and preservation of the left colic artery using real-time lymph node mapping with indocyanine green. All patients were divided into two study groups: Group I included 45 patients who underwent anterior or low anterior resection of the rectum with preservation of the left colic artery. This group was subdivided into two subgroups: Ia – 13 patients who underwent intraoperative indocyanine green injection for real-time lymph node visualization. Ib – 32 patients who did not receive this drug but underwent the same volume of surgery. Group II consisted of 43 patients who underwent anterior or low anterior resection of the rectum with high ligation of the inferior mesenteric artery. This group served as the control group. Results. The main mechanisms of lymphogenic metastasis in colorectal cancer patients in Ivano-Frankivsk were characterized. Literature data on the features of surgical diagnostics of colorectal cancer metastasis were summarized. A review of literature shows the social significance of these studies, as this pathology often leads to patient disability, requiring surgical interventions and further palliative treatment due to the widespread metastasis associated with this disease. The priority task for researchers remains the search for the most effective treatment methods for this pathology, based on randomized studies of colorectal cancer treatment and international protocols. According to the literature, surgical treatment of colorectal cancer remains insufficiently effective at the current stage of oncology. Modern methods offer low 5-year survival rates, emphasizing the need to study factors for individualized treatment. The overall 5-year survival rate for colorectal cancer patients from 2018-2022 was (45.8±2.3)%. The effectiveness of using real-time ICG navigation for lymph node mapping and preservation of the left colic artery in stage II-III (T2-4N1-2M0) rectal cancer patients has been proven. This technique allows for optimal lymphadenectomy, reducing the frequency of surgical complications by 14.7% (p&lt;0.05). Conclusion. Ensuring radical resection of rectal cancer while maximizing blood supply preservation to the anastomosis is the main goal of colorectal surgeons. Over the past two decades, surgical techniques have significantly improved due to advancements in surgical equipment. It is anticipated that surgical technologies will further evolve towards enhancement and individualization in the future. Our procedure serves as an example of modern and personalized rectal cancer surgery.

6728 Bilateral Adrenal Hemorrhage: Cause Or Consequence?

Abstract Disclosure: M.N. Rayan: None. R. Horner: None. A. Valenciaga: None. L.E. Ryan: None. Introduction: Before the advent of the CT scan, bilateral adrenal hemorrhage was primarily discovered post-mortem in patients who had succumbed to sepsis, burns, or anticoagulant therapy. Today, non-traumatic hemorrhage is recognized as an infrequent, yet potentially lethal diagnosis causing clinical deterioration in acutely ill patients. Clinical Case: Our patient is a 64-year-old-male with a medical history of Myelodysplastic Syndrome initially presented to an external ED with abdominal pain. CT abdomen revealed hepatomegaly, splenomegaly, and new bilateral adrenal masses—absent in an MRI conducted a year earlier. He was treated conservatively and subsequently discharged. Two weeks later, he returned to the hospital with severe right sided flank pain. His hemoglobin and platelet counts dropped from 11.5 g/dL and 309 K/uL during the previous ED visit to 7.7 g/dL and 80 K/uL, respectively. Additionally, his PT/INR, PTT, fibrinogen, and D-Dimer levels were elevated. A repeat CT scan indicated a significant enlargement of the right adrenal mass, raising suspicion of adrenal hemorrhage. He was appropriately transfused, and a BM biopsy was performed to evaluate for acute transformation of underlying MDS. Cortisol levels were monitored daily for adrenal insufficiency. A complicated hospital course ensued marked by worsening anemia, thrombocytopenia, and coagulopathy, accompanied by high fevers and new-onset atrial fibrillation. Mixing studies showed absence of a factor inhibitor ruling out acquired forms of Hemophilia. Infectious workup including fungal and viral serologies returned negative. A PET scan revealed several small hypermetabolic hypodense liver lesions, and hypermetabolic activity diffusely in the spleen, and adrenal glands leading to suspicion of metastasis. Results of the BM biopsy returned revealing hypercellularity, with aggregates of hemosiderin-laden macrophages replacing the bone marrow space with associated necrosis. Worsening abdominal pain with hematochezia prompted an endoscopy, confirming a diagnosis of metastatic melanoma. Concurrently, seizure activity and altered mentation led to a head CT, revealing new metastatic lesions that confirmed the rapid progression of the disease. Subsequently, the patient was transitioned to comfort care and passed away. Clinical Lesson: It is crucial to review the various causes of adrenal hemorrhage, understand the challenges associated with interpreting adrenal imaging, emphasize the need to monitor adrenal function, and consider the occasional necessity for tissue sampling. In this clinical scenario, metastases with hemorrhage were the most likely etiology. The causes of adrenal hemorrhage are not always apparent; in this presentation, the consequence of the underlying disease state ultimately led to the initial presenting symptom of abdominal pain.

A short duration of mechanical ventilation alters redox status in the diaphragm and aggravates inflammation in septic mice

BackgroundMechanical ventilation (MV) is a life support method used to treat patients with respiratory failure. High tidal volumes during MV can cause ventilator-induced lung injury (VILI), but also affect other organs, such as the diaphragm (Dia) causing ventilator-induced diaphragmatic dysfunction (VIDD). VIDD is often associated with a complicated course on MV. Sepsis can induce inflammation and oxidative stress, contributing to the impairment of the Dia and worsening of the prognosis. This study evaluated the additive or synergistic effects of a short course of mechanical ventilation on Dia in healthy and septic adult mice. Methods32 adult male C57BL/6 mice were randomly into four groups: Control (CG), non-ventilated animals instilled with saline solution (PBS1x); Lipopolysaccharide (LPS), non-ventilated animals instilled with PBS solution containing lipopolysaccharide; Mechanical Ventilation (MV) for 1 h, ventilated animals instilled with PBS solution; and Mechanical Ventilation and LPS (MV+LPS), ventilated animals instilled with PBS solution containing LPS. At the end of the experimental protocol, the animals were euthanized, then blood and diaphragm tissue samples were collected. ResultsEvaluation of leukocyte/blood parameters and diaphragm muscle showed that MV, LPS and the combination of both were able to increase neutrophil count, creatine kinase, inflammatory mediators and oxidative stress in all groups compared to the control. MV and sepsis combined had additive effects on inflammation and lipid peroxidation. ConclusionsA short course of Mechanical ventilation promotes inflammation and oxidative stress and, its combination with sepsis further increases local and systemic inflammation.

Maternal and newborn outcomes in patients with endometriosis-associated infertility

Aim. To identify the characteristics of pregnancy and childbirth in women with endometriosis-associated infertility (EAI).Materials and Methods. Here we performed retrospective case-control study which included 115 women with histologically verified endometriosis and 250 women without this condition. Statistical analysis was conducted using the IMB SPSS Statistics 20 software package. The data distribution was assessed using the Kolmogorov-Smirnov test. Quantitative data are presented as median (Me) and interquartile range (Q1 – Q3) using the Mann-Whitney test. The level of statistical significance for testing the null hypothesis was set at p &lt; 0.05.Results. Pregnancy in patients with EAI was statistically significantly more often complicated by placenta previa compared to the control group: 6 (5.2%) versus 3 (1.2%) (p = 0.031). Patients with EAI were delivered via cesarean section in 49.6% of cases, compared to 13.2% in those without EAI (p &lt; 0.001). Labor in women with EAI was statistically significantly more often complicated by uterine inertia (hypotonic labor, 7.0% versus 2.4% in those without EAI, p = 0.043), retained placenta (4.3% vs 0.4%, p = 0.013); and hypotonic bleeding (3.5% vs 0.4%, p = 0.036). Maternal and neonatal outcomes including birth weight, Apgar scores at 1 and 5 minutes, and the duration of hospital stay did not differ significantly between the groups.Conclusions. Patients with EAI are characterized by a complicated course of pregnancy and childbirth with a higher incidence of placenta previa, abnormal labor, hypotonic bleeding, retained placenta, and cesarean delivery. Hence, the development of respective therapeutic and preventive measures is required to prevent these complications.

Clinical case of complicated and recurrent course of Cl. difficile-associated colitis in a child under 1 year of age

Currently, antibiotic-associated diarrhea caused by Clostridioides difficile (Cl. difficile) is one of the problems of the health care system in many countries of the world and the main causative agent of healthcare-associated infections. The article describes a clinical case from our own practice of the occurrence of Cl. difficile associated diarrhea (CDI) in a child in the first year of life. In the described clinical case, the child developed the first episode of CDI against the background of antibiotic therapy, which, due to the inadequate duration of treatment, led to a relapse of the disease and the development of complications in the form of sepsis. Thus, with clinical case, we want to draw the attention of practitioners to the problem of CDI in young children. Currently, despite significant changes in the diagnosis of CDI, the diagnosis of CDI in young children is challenging, requiring the development of accurate diagnostic criteria for diagnosis and the definition of additional diagnostic markers to distinguish healthy carriage from disease.

The role of coronavirus infection in lung injury, which contributes to the occurrence of complicated course of community-acquired pneumonia

Annotation. The review article focuses on the role of coronavirus infection in lung damage, which contributes to the complicated course of community-acquired pneumonia. Based on the scientometric databases Web of science, Scopus, PubMed, a retrospective analysis of the literature on this topic for 2013-2023 was conducted. 32 sources were selected after reviewing the abstracts of the articles and reading their full text. The results of the search indicate that most people infected with SARS-CoV-2 do not develop severe illness, and the infection is likely to be limited to the upper respiratory tract. However, in some people, infection with the virus leads to severe pneumonia dominated by immunopathology, probably caused by lower respiratory tract infection. Alveolar damage can be a direct consequence of cell infection or an indirect consequence caused by local inflammatory reactions. People with severe COVID-19 often have a tendency to have a delayed immune response. Inflammation and coagulation further exacerbate pro-inflammatory and/or profibrotic reactions, which contributes to the development of complications. Uncontrolled inflammation ultimately leads to severe immunopathology characteristic of COVID-19. In this regard, understanding the pathogenesis of SARS-CoV-2 infection and how it contributes to critical illness and its complications may help to improve risk allocation and develop targeted therapies to reduce the acute and long-term consequences of this disease.

Comparison of Outcomes after Autologous Breast Reconstruction: Latissimus Dorsi with Immediate Fat Transfer versus Abdominally Based Free Flaps.

Autologous breast reconstruction confers favorable patient reports of satisfaction and quality of life compared with implant-based reconstruction over a lifetime. The latissimus dorsi with immediate fat transfer (LIFT) is an alternative approach to abdominally based free flaps (Ab-FF), which expands fully autologous reconstruction to nonmicrosurgeons. This study compared the 2 procedures concerning their clinical and patient-reported outcomes 1 year postoperatively. The authors conducted a retrospective review of LIFTs and Ab-FFs performed between March of 2017 and August of 2022. The primary outcomes were postoperative complications, reoperations, and longitudinal BREAST-Q scores. BREAST-Q modules included Satisfaction with Breasts, Satisfaction with Abdomen, Satisfaction with Back, Psychosocial Well-being, Physical Well-being: Chest, Physical Well-being: Abdomen, Physical Well-being: Back, and Sexual Well-being. Of the 281 included patients (408 breasts), 211 received Ab-FF and 70 received LIFT. One-year follow-up (median [interquartile range], 12 [12] months) demonstrated that Ab-FF independently predicted dehiscence, reoperation procedures, and revisional surgery. LIFT independently increased the odds of seroma. Obesity predicted dehiscence, and bilateral reconstructions predicted revisional fat grafting. BREAST-Q scores fluctuated over time but were similar across all measured domains by 1 year postoperatively. Although Ab-FF is the standard approach for fully autologous reconstruction, LIFT procedures may be associated with a less complicated postoperative course while eliciting similar patient-reported outcomes. LIFT may be preferred to limit postoperative complications, particularly in patients with obesity. LIFT can be used by plastic surgeons who are not trained in microsurgical procedures or do not have an environment that fosters Ab-FF. Therapeutic, III.
