The debut of benign recurrent intrahepatic cholestasis in acute hepatitis A

Background. Benign recurrent intrahepatic cholestasis is a rare inherited disorder characterized by recurrent episodes of severe hyperbilirubinemia and pruritus that resolve spontaneously. However, attacks of cholestasis may persist for several months and in some cases be associated with frequent recurrences, which may be grounds for liver transplantation.Objective. To present a clinical case of debut benign recurrent intrahepatic cholestasis following acute hepatitis A.Results. A 30-year-old patient was admitted at the Liver Transplantation Center of Moscow Regional Research and Clinical Institute n.a. M.F. Vladimirskiy for a prolonged episode of intrahepatic cholestasis with severe coagulopathy after acute hepatitis A. Total bilirubin was elevated up to 835 µmol/L and INR was 3.6. The manifestations of vitamin K-associated coagulopathy were controlled after the first dose of parenteral menadione sodium bisulfite. Glucocorticosteroids, ursodeoxycholic acid and plasmapheresis turned ineffective in the treatment of hyperbilirubinemia. Due to long-persisting cholestasis resistant to conservative therapy, the patient was considered for inclusion to the liver transplant waiting list. However, spontaneous resolution of the cholestatic episode was achieved at 5 months after the onset of manifestations. Benign recurrent intrahepatic cholestasis type 2 was diagnosed on the basis of the specific clinical signs, laboratory blood tests and genetic testing.Conclusion. The present Case Report shows a long-lasting episode of cholestasis with severe coagulopathy in acute hepatitis A in a patient with benign recurrent intrahepatic cholestasis with subsequent spontaneous resolution of the clinical symptoms at 5 months after their manifestation onset. Therefore, the differential diagnosis of benign recurrent intrahepatic cholestasis should be considered prior to liver transplantation in patients with intrahepatic cholestasis.

The safety of valproic acid treatment in children with epilepsy: a retrospective real-world research

BackgroundLiver damage, coagulopathy, hyperammonemia, fracture, menstrual disorder and amenorrhea are the most concerned adverse drug reactions of valproic acid (VPA). This study was aimed to retrospectively investigate the incidence of adverse drug reactions of VPA in the real world and its association with the age of patients and duration of treatment in order to obtain the safety data of VPA in children with epilepsy.MethodsA total of 1943 patients diagnosed as epilepsy by the Pediatric Neurology Department of Shenzhen Children’s Hospital between December 2013 and December 2023, were included in the study. They received VPA as an initial treatment, and had followed up examinations over a time span of at least two years focusing on the adverse drug reactions of VPA.ResultsThere was no significant difference in the incidence of liver damage, coagulation test abnormalities, and nasal bleeding during VPA monotherapy (30–90 days, 90–180 days, and > 2 years). Adolescent female patients (first visit age ≥ 12 years) showed no significant difference in the incidence of adverse reactions and abnormal ultrasound of the reproductive system pre- versus post-treatment at the first visit, similar for those below 12 years. However, laboratory blood tests revealed significantly age-dependent changes in certain biochemical markers. Two patients stopped VPA treatment due to thrombocytopenia and ovarian cystic mass comorbid with endometrial hyperplasia, recovering after VPA withdrawal. ConclusionsThe initial monotherapy of VPA is generally safe in children with epilepsy of all age ranges. In the real world, VPA does not increase the risk of liver damage, coagulation disorder, elevated blood ammonia, fractures, or low serum sodium, but may significantly decrease the platelet count at 3, 6, 12, and 24 months of treatment. There is no evidence showing that VPA may increase the incidence of impairment of adolescent female reproductive system. Among children under 1 year old, it is recommended to monitor the levels of serum ammonia and aspartate aminotransferase carefully.Trial registrationChiCTR2300075115.

Explainable predictions of a machine learning model to forecast the postoperative length of stay for severe patients: machine learning model development and evaluation.

Predicting the length of stay in advance will not only benefit the hospitals both clinically and financially but enable healthcare providers to better decision-making for improved quality of care. More importantly, understanding the length of stay of severe patients who require general anesthesia is key to enhancing health outcomes. Here, we aim to discover how machine learning can support resource allocation management and decision-making resulting from the length of stay prediction. A retrospective cohort study was conducted from January 2018 to October 2020. A total cohort of 240,000 patients' medical records was collected. The data were collected exclusively for preoperative variables to accurately analyze the predictive factors impacting the postoperative length of stay. The main outcome of this study is an analysis of the length of stay (in days) after surgery until discharge. The prediction was performed with ridge regression, random forest, XGBoost, and multi-layer perceptron neural network models. The XGBoost resulted in the best performance with an average error within 3days. Moreover, we explain each feature's contribution over the XGBoost model and further display distinct predictors affecting the overall prediction outcome at the patient level. The risk factors that most importantly contributed to the stay after surgery were as follows: a direct bilirubin laboratory test, department change, calcium chloride medication, gender, and diagnosis with the removal of other organs. Our results suggest that healthcare providers take into account the risk factors such as the laboratory blood test, distributing patients, and the medication prescribed prior to the surgery. We successfully predicted the length of stay after surgery and provide explainable models with supporting analyses. In summary, we demonstrate the interpretation with the XGBoost model presenting insights on preoperative features and defining higher risk predictors to the length of stay outcome. Our development in explainable models supports the current in-depth knowledge for the future length of stay prediction on electronic medical records that aids the decision-making and facilitation of the operation department.

Unilateral Vestibular Hypofunction in an Adolescent: Case Report and Literature Review

Objective − The report presents a case of an adolescent girl with vertigo resulting from unilateral vestibular hypofunction, diagnosed after extensive pediatric and otorhinolaryngological evaluations.Case Report − A seventeen-year-old female adolescent sought medical assistance at the pediatric emergency hospital service on several occasions within one year due to feelings of weakness and darkened vision occurring during abrupt standing, exposure to heat, and stress. Symptoms were initially attributed to school obligations, low blood pressure, and the menstrual cycle. After an episode that also involved a brief loss of consciousness, an extensive neurological evaluation was conducted, excluding epileptogenic causes. Subsequent diagnostic procedures included evoked visual potential tests, psychological assessments, laboratory blood tests, thyroid hormone assays, and Borrelia burgdorferi serology, all yielding normal results. Finally, otorhinolaryngological examinations were performed, including pure tone audiometry, tympanometry, video head impulse tests, videonystagmography, and vestibular evoked myogenic potential tests. These tests indicated symptoms arising from unilateral labyrinthine hypofunction of the inner ear. The patient underwent vestibular rehabilitation, resulting in symptom resolution and confirmed functional recovery.Conclusion − Diagnosing vertigo in adolescence is challenging, as impaired balance can manifest as a symptom of various diseases. Presentation with atypical symptoms for peripherally caused balance disorders complicates diagnosis. Otorhinolaryngologists and audio-vestibular diagnosticians play pivotal roles in establishing accurate diagnoses.

Practice in bronchiolitis management in Polish hospitals—a multicenter retrospective cohort study

Bronchiolitis is one of the main reasons for the hospitalization of young children. Based on updated recommendations, only supportive therapy is recommended for treatment. In Poland, many children that are hospitalized with bronchiolitis undergo a treatment that is not supported by current research. The study aimed to assess clinicians’ adherence to the guidelines. This was a multicenter retrospective study of hospitalized infants with bronchiolitis; a cohort study design was utilized. Data were collected in four Pediatric Departments in Poland. All infants aged less than 24 months that had been hospitalized for their first and subsequent episodes of acute bronchiolitis from January 1, 2021, to December 31, 2022, were included. The exclusion criterion was an age over 24 months. A total of 629 infants with a median age of 8.5 months were included in this study. The medical interventions and treatments varied between the four hospitals. Laboratory blood tests were run for almost all children (99.5%), and the percentage of children for which a chest X-ray was performed ranged from 1.3% to 44%. The other measures were the use of intravenous hydration (51.3%-93.3%), use of hypertonic saline nebulization (1.3%-43.6%), use of normal saline nebulization (10%-95.1%), use of oxygen (7.3%-42%), use of beta-mimetics (19.1%-89.4%), use of nebulized steroids (8%-76.9%), use of systemic steroids (0.9%-42%), use of nebulized adrenaline (0%-8.1%), and use of antibiotics (12%-21.8%).Conclusions: In total, 70% of infants who were hospitalized in four hospitals in Poland underwent examinations and treatment methods that are not supported by current guidelines and evidence-based research. This study shows that non-recommended medications are overused in bronchiolitis treatment, and there is a need to take action to implement the guidelines into healthcare providers’ work.What is Known:• Bronchiolitis is a lower respiratory tract viral infection and is one of the main reasons for hospitalization among young children.• Only supportive therapy is recommended in the guidelines.• Bronchodilators, nebulized adrenaline, nebulized or systemic steroids, and antibiotics are not recommended.What is New:• Non-recommended medications are overused in bronchiolitis treatment in Poland.• Up to 70% of hospitalized children in the studied centers underwent treatment that is not supported by guidelines.

Canal to calcar ratio is associated with lumbar compression fractures

Objective: Osteoporosis is one of the major public health problems. Singh (SI) and Genant indexes are the most well-known osteoporosis evaluation methods. Femoral cortical thickness index (CTI) and femoral canal to calcar ratio (CCR) values have been found to be more informative in the literature. This study aimed to investigate the relationship between SI, CTI, CCR, bone mineral density, and blood tests. Patients and Methods: Hospital digital archives were searched and postmenauposal female patients who underwent bone scanning between 2018 and 2020 were included. Demographic data, blood laboratory and bone mineral densitometry (BMD) test results, and radiographic views were collected. The results were statistically analysed and expressed as mean ± standard deviation. Results: The mean age was 66.14±6.82 years. There were 22 patients with lumbar compression according to Genant criteria. Also, 52 patients had osteoporosis and 35 patients had osteopenia according to the spine or hip BMD T scores. CCR was found to be significantly related to lumbar compression (p=0.04). Conclusion: In this study, no correlation was found between CCR value and T score. However, CCR value was found to be associated with lumbar vertebral compression, which is helpful in the diagnosis of osteoporosis. It may be considered as a parameter that should be studied more in the diagnosis of osteoporosis.

The severity of metabolic derangement predicts survival of out-of-hospital cardiac arrest and the benefit of extracorporeal life support

Abstract Aims This study aimed to develop Metabolic Derangement score and validate its prognostic performance in patients with out-of-Hospital Cardiac Arrest (OHCA) and also its discriminative performance in guiding the application of extracorporeal life support (ECLS). Methods and Results From 5,100 patients (average age 67 years, 69% male), Metabolic Derangement score was developed to predict primary outcome (death or poor neurologic outcome, cerebral performance category ≥ 3 at day 30) from initial blood laboratory test including pH, PaCO2, PaO2, potassium, haemoglobin, lactate, and creatinine. It was created using machine learning algorithms and a training set (60%), and validated with a test set (40%). The risk of primary outcome consistently increased from 34% to 100% as the Metabolic Derangement score ranged from 0 to 7. Patients with Metabolic Derangement score ≤ 2 showed no difference in the primary outcome risk between those with or without ECLS. Conversely, those with a Metabolic Derangement score ≥3 had a lower risk with ECLS (difference of restricted mean survival time=6.5 days, 95% CI=3.3-9.6 days, ratio of restricted mean time lost=0.76, 95%CI=0.65-0.88, all p<0.001). Clinical subgroup analyses showed generally consistent results. Metabolic Derangement score also outperformed OHCA-, CAHP-, and NULL-PLEASE-scores in prediction the primary outcome (p<0.05, all). Conclusions The severity of metabolic derangement predicted the clinical outcome of OHCA, and could also identify patients likely to benefit from ECLS.Metabolic Derangement score

How can we reduce healthcare costs by using Enhanced Recovery After Surgery more effectively in different groups of gynaecological patients? A single-centre experience.

The objective of this study was to assess the impact of the Enhanced Recovery After Surgery (ERAS) programme implementation on treatment costs at a university-type centre, using the DRG scheme. Retrospective analysis of patients' data in a group of 604 individuals enroled in the study. We evaluated three groups of patients according to the ERAS clinical protocol (CP): (1) CP oncogynaecology, (2) CP simple hysterectomy, (3) CP laparoscopy. The study aimed to evaluate the impact on the length of stay (LOS), savings in bed-days, and the reduction in direct treatment costs. Three parameters-antibiotic consumption, blood derivative consumption and laboratory test costs-were chosen to compare direct treatment costs. The statistical significance of the difference in the observed parameters was tested by a two-sample unpaired t test with unequal variances at the 0.05 significance level. We analysed data from 604 patients. In all three groups, the length of stay (LOS) was significantly reduced. The most significant reduction was observed in the CP oncogynaecology group, where the LOS was reduced from 11.1 days to 6.8 days (2022) and 7.6 days (2023) compared to 2019 (p < 0.05). Furthermore, there was a notable reduction in inpatient bed-days, which resulted in the capacity being made available to admit additional patients. A statistically significant reduction in direct costs was observed in the group of CP hysterectomy (antibiotic use) and in the CP laparoscopy (laboratory test costs). The implementation of the ERAS principles resulted in a number of significant positive economic impacts-reduction in the LOS and a corresponding increase in bed capacity for new patients. Additionally, direct treatment costs, including those related to antibiotic use or laboratory testing were reduced. The Czech Republic's acute healthcare system, like the majority of European healthcare systems, is financed by the DRG system. This flat-rate payment per patient encourages hospital management to seek cost-reduction strategies. The results of our study indicate that fast-track protocols represent a potential viable approach to reducing the cost of treatment while simultaneously meeting the recommendations of evidence-based medicine.

The Advancement of Appendicitis in Children in the Pre-Pandemic and the Pandemic Year.

Background: The COVID-19 pandemic affected the health of millions of people, both directly through infection and indirectly through delayed diagnosis and treatment of non-COVID-19 illnesses. The aim of this study was to check the impact of the COVID-19 pandemic on the diagnosis and treatment of appendicitis in children. Methods: The study was carried out at the Department of Paediatric Surgery of the Marciniak Hospital (Wrocław, Poland) and covered two periods, the pre-pandemic one (P1, 01/03/2019-29/02/2020) and the pandemic one (P2, 01/03/2020-28/02/2021). Results: The number of admissions of patients with suspected appendicitis and observation-only patients decreased during the pandemic (400/289 and 226/160, respectively). Although the number of operated children was similar during both analyzed periods (P1: 174, P2: 160), the rate of surgical interventions was significantly higher during P2 (55.4%) than during P1 (43.5%) (χ2 test: p = 0.00272). The values of the variables quantifying disease progression and severity of inflammation, selected inflammation-related parameters detected by laboratory blood tests, latencies from the onset of symptoms to the admission and from the admission to the operation, and total duration of hospitalization did not differ significantly between the pre-pandemic and pandemic periods. Conclusions: These results show that the COVID-19 pandemic led to more rigorous and careful triage of pediatric patients suspected of acute appendicitis that did not have a negative impact on patient outcomes.

INTEGRATIVE INDICATORS OF ENDOGENOUS INTOXICATION, INFLAMMATORY ACTIVITY, AND SPECIFIC REACTIVITY IN PATIENTS WITH COVID-19

The aim of the study is to identify changes in blood laboratory parameters, integrative indicators of endogenous intoxication, inflammation, and specific reactivity in patients with coronavirus disease. Patients and methods. The study included 77 patients with COVID-19, taking into account the inclusion and exclusion criteria. The comparison group consisted of 68 practically healthy people of the corresponding age. Laboratory blood tests were performed, on the basis of which integrative indicators of endogenous intoxication, inflammation and specific reactivity were calculated. Results. The data of the general blood test showed no significant differences between the patients of the groups, the indicators remained within acceptable limits. A slight inflammatory reaction in patients with COVID-19, especially in the period from 3 to 6 months, is confirmed by an increase in the level of endogenous intoxication (LII, LSI, NLRI, HII) in the group of patients compared to healthy individuals. During the same period, there are signs of activation of the cellular immune system in response to the presence of latent bacterial infection or endogenous intoxication, which is confirmed by a decrease in inflammation activity (LGI, LESRI, CI). Reduced indices of nonspecific reactivity (RC, ILYM, AI) confirmed the activation of the cellular immune system, given the decrease in the number of lymphocytes relative to granulocytes. Changes in integrative indices did not depend on the presence of Long-COVID symptoms. In the period from 12 months after the coronavirus disease, the development of autoimmune processes is possible, since there was a tendency to decrease the indices of endogenous intoxication (NLRI, LSI) simultaneously with an increase in the indices of inflammatory activity (LGI, LESRI, TI) and indices of nonspecific reactivity (RC, Ilymph, AI).

Icteria interference for 34 clinical chemistry analytes on different analytical platforms: Method or analyzer dependent?

ObjectivesIn this study, we aimed to investigate the effect of increasing bilirubin concentration on 34 commonly measured clinical chemistry analytes on four different analytical platforms. We hypothesized that differences in icteria interference are not only method dependent, but also analyzer dependent. MethodsSerum pool was prepared using leftover samples after routine laboratory blood testing. Serum pool was then spiked with dissolved bilirubin stock. Measurements were performed on all four locations at the same time. All measurements were done in duplicate. Mean value was calculated as: (value1 + value2)/2. Those values were multiplied by corresponding dilution factors obtained during the preparation of icteric samples. For each icteric sample (Ix), bias against native (I0) sample was calculated as ((value Ix– valueI0)/ valueI0) × 100 %. Bias was calculated with actual average values. Obtained bias values were compared against acceptance criteria according to External quality assurance (EQA) providers. Difference in bilirubin concentration across platforms was tested using Friedman ANOVA. P values < 0.05 were considered statistically significant. Data are collected and analyzed in MS Excel 2016 (Microsoft, Redmond, Washington) and MedCalc® Statistical Software version 20.015 (MedCalc Software Ltd, Ostend, Belgium). ResultsMany of the tested parameters demonstrated low sensitivity to icterus interference. The highest sensitivity to icterus was observed for triglycerides, cholesterol, and urate. ConclusionsOur results indicate that while some common icteric interferences were consistent across all tested platforms, others were specific to the analyzer used, even when employing the same analytical methods.

Comparative analysis of medial pivot vs. posterior stabilized total knee arthroplasty in patients with valgus deformed osteoarthritic knees: a retrospective cohort study.

Total knee arthroplasty (TKA) is highly effective for end-stage knee osteoarthritis, providing long-term benefits and anticipated increased prevalence. The study compares Medial Pivot TKA's (MP-TKA) historical success for varus deformities with recent findings suggesting comparable outcomes for valgus deformities. Despite prevalent use of Posterior Stabilized TKA (PS-TKA) for valgus deformities, this research explores the unexplored comparative efficacy of MP-TKA vs. PS-TKA in knee osteoarthritis patients with valgus deformity. This single-centrecohort study focused on 57 knees in 53 patients undergoing TKA for knee osteoarthritis with valgus deformity. Conducted between January 2013 and April 2021, the study compared MP-TKA and PS-TKA. Surgeries adhered to a medial parapatellar approach and modified gap technique, with perioperative interventions for pain, bleeding, and swelling. Outcome measurements included knee joint range of motion, radiographic evaluation, patients-reported outcomes, operative time, blood laboratory tests, estimated blood loss, and postoperative adverse events, and analyzed between the two groups. Postoperative hip-knee-ankle angles showed no significant difference between MP-TKA and PS-TKA. The pie crust technique was similarly used in both groups, and deformity correction showed no significant difference. Range of motion and clinical outcomes, measured by WOMAC and JOA scores, were comparable postoperatively. MP-TKA had a shorter surgical duration (p = 0.01), and PS-TKA exhibited higher estimated blood loss (p = 0.01) without significant complications in either group. This pioneering study compares the outcomes of MP TKA and PS TKA in patients with valgus-deformed osteoarthritic knees. Compared to PS TKA, MP TKA shows a prolonged operative duration and increased blood loss, likely due to the requirement for patellar replacement. However, postoperative range of motion and clinical outcomes are similar. Both groups exhibit favorable midterm clinical results, supporting the viability of MP TKA for valgus deformed knees. The study, consistent in surgical approach, highlights MP TKA's effectiveness for valgus deformities.

Cryptosporidiosis in puppies: clinical and epizootical characteristics

Gastrointestinal diseases of puppies aged 2–6 months account for 62% of all pathologies of these animals registered in the clinic. The lifestyle of dogs is associated with close tactile contact with the environment. The presence of protozoa in the digestive tract causes the inclusion of its representatives in the pathological process, which leads to the complication of disorders that have arisen due to various etiological factors. The study aimed to determine the role of the ubiquitous protozoa Cryptosporidium spp. in the pathogenesis of digestive tract diseases in puppies. General clinical, laboratory tests of blood (haematological, biochemical), faeces (coprogram, parasitological), statistical processing were performed. It was found that protozoa were detected in 52 % of sick animals with digestive disorders. The protozoan fauna included Cryptosporidium spp. (100 %), Isospora spp. (29 %), Giardia lamblia (21 %). Animals with cryptosporidium were examined without associations. The manifestation of the disease was noted most often in puppies with weak immune system functions, especially in the age group of 4–5 months, which is associated with the period of tooth change and a decrease in the overall immunological reactivity of the body. Clinically, the disease is characterized by enteritis development with accompanying symptoms. A characteristic clinical sign that should guide further diagnostic search is watery diarrhoea with an unpleasant odour, foamy, mucus, sometimes blood streaks. Laboratory findings include hypoalbuminemia with a decrease in the albumin-globulin ratio, hyperbilirubinaemia due to conjugated bilirubin, hyperfermentation of indicator enzymes of the liver and pancreas, and uremia. Such indicators indicate concomitant insufficiency of the digestive glands – the liver and pancreas, and a general inflammatory reaction. In coprological diagnostics, the qualitative data of the coprogramme confirm the lesions of the small intestine, liver and pancreas. Examination of fecal smears stained by the Ziehl-Nielsen method revealed cryptosporidium oocysts. The average intensity of invasion was 786.4 ± 23.1 oocysts per gram of feces.

Рослинні компоненти в комплексній терапії гострого циститу в жінок: оптимізація ефективності, профілактика та безпечність

Aim - to study anti-inflammatory and antioxidant effects of phytochemicals in young women with acute cystitis. Materials and methods. The study included 50 women with acute cystitis aged between 18 and 35 years. The patients were divided into two groups. The control group (n=25) received standard antibacterial therapy for 7 days, and patients in the intervention group (n=25) additionally took a combined herbal preparation at a dosage of 1 capsule twice a day for 30 days and then a further 60 days at a dosage of 1 capsule once a day. Follow-up visits were made 7 days, 1 month and 3 months after the start of treatment. During the study, the dynamics of the complaints, the results of the ACSS questionnaire, laboratory tests of urine and blood were evaluated, and the parameters of the oxidative stress-antioxidant status system were determined. Results. After the course of etiotropic treatment, it was found that the average duration of acute cystitis` symptoms in the control group was 1.67 times longer than in the intervention group. After one month of taking the herbal combination drug, the antioxidant defence system was stabilized: the indicators of oxidative stress in the intervention group had a significantly greater positive dynamic than in the control group; the indicators of the antioxidant system reached normal levels and had significant differences compared to the control group. In the intervention group, there was a restoration of neutrophil membrane-associated pyridine nucleotide oxidase activity and an increase in the functional reserve of phagocytic cells, a significant increase in the number of cells capable of phagocytosis was noted, and the absorptive activity of neutrophils was also significantly higher than in the control group. During the 3-month prophylactic course of treatment with the herbal remedy, the absence of recurrent disease was observed in 96% of patients in the intervention group, in contrast to the control group, where the absence of reinfection was observed in only 72% of patients. Conclusions. The use of a combined herbal preparation at a dosage of 1 capsule twice a day in addition to standard therapy for acute cystitis in women significantly reduces the duration of clinical symptoms and promotes faster clinical and laboratory recovery. After 30 days of use, oxidative stress, antioxidant protection and phagocytic activity of neutrophils are normalized. Complex therapy of acute cystitis with the inclusion of herbal medicine for 3 months is associated with a significantly lower number of cases of urinary tract reinfection compared with treatment without herbal medicine. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors.

Liver function assessment based on hepatobiliary contrast agent-enhanced magnetic resonance imaging

BACKGROUND: Liver function assessment is very important in clinical practice. The use of magnetic resonance imaging for the anatomical and functional evaluation of the liver is possible in actual clinical practice. AIM: To examine the possibility of using hepatobiliary contrast-enhanced magnetic resonance imaging for the evaluation of liver function. MATERIALS AND METHODS: Datasets of patients who underwent gadoxetic acid-enhanced magnetic resonance imaging were retrospectively reviewed. Patients were divided into two groups: group 1 included patients with impaired liver function, and group 2 included those with normal liver function. Based on magnetic resonance imaging in the hepatobiliary phase, the liver parenchyma signal intensity and its ratio to spleen signal intensity and portal vein signal intensity were estimated. Differences among these parameters were compared between groups. The correlation between liver parenchyma signal intensity and laboratory blood tests reflecting liver function (total bilirubin, albumen, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma glutamyl transpeptidase, and prothrombin time) were analyzed. RESULTS: Datasets of 53 patients (25 men and 28 women, aged 24–84 years) were analyzed. Group 1 included 19 patients, whereas group 2 included 34. The median liver parenchyma signal intensity was 919.05 [669.65; 1258.35] in group 1 and 1525.13 [1460.5; 1631.4] in group 2 (p=0.0000001). The median ratio of liver parenchyma signal intensity to spleen signal intensity was 1.2 [1.04;1.7] in group 1 and 1.7 [1.46; 1.96] in group 2 (p=0.00076). The median ratio of liver parenchyma signal intensity to portal vein signal intensity was 1.44 [1.29; 1.83] in group 1 and 1.6 [1.43; 1.83] in group 2 (p=0.1). The estimated correlation values between liver parenchyma signal intensity and blood tests parameters were as follows: total bilirubin (r=–0.61; p=0.000001), albumen (r=0.13; p=0.61), aspartate aminotransferase (r=–0.57; p=0.000009), alanine aminotransferase (r=–0.44; p=0.001), alkaline phosphatase (r=–0.45; p=0.0007), gamma glutamyl transpeptidase (r=–0.5; p=0.0003), prothrombin time (r=–0.34; p=0.04). CONCLUSION: The study reflects the ability to assess liver function using indices (liver parenchyma signal intensity and its ratio to spleen signal intensity) derived from gadoxetic acid-enhanced magnetic resonance imaging. However, this study did not confirm the assumed effectiveness of using the liver parenchyma signal intensity to portal vein signal intensity ratio as an index of liver function. A significant inverse correlation was identified between liver parenchyma signal intensity and blood test parameters in reflecting liver function, except for albumin. The results indicate the possibility of using magnetic resonance imaging to assess liver function.

Nutritional disorders as a predictor of rapid diagnosis and disease progression in patients with amyotrophic lateral sclerosis

Background: One of the symptoms of amyotrophic lateral sclerosis (ALS) is progressive loss of body weight. Moreover, in various forms of ALS, regardless of the presence of dysphagia at the onset of the disease, there are similar changes in nutritional status. The problem of nutritional support in patients with ALS, as well as monitoring nutritional status over time in this group of patients remains relevant. Purpose: to evaluate the severity and rate of increase in nutritional disorders in patients with ALS and their relationship with the rate of disease progression, as well as the life expectancy of these patients. Materials and methods: The study included 49 patients diagnosed with ALS who died from 2018 to 2023. All participants underwent a neurological examination, measurement of anthropometric parameters, and laboratory blood tests; 61 % (n=30) of the patients underwent bioimpedance analysis of body composition over time. Results: The highest rate of body weight loss was recorded in the group of patients with quickly diagnosed ALS: it accounted for 1.9 (1.6; 2.2) kg/month. The highest rate of loss of skeletal muscle mass was noted in the same group of patients at 0.4 (0.38;0.46) kg/month. In the group with a quickly diagnosed disease, only 20 % of the patients underwent gastrostomy insertion; in the group with a slow diagnosis rate, 25 % of the patients underwent gastrostomy; only 50 % of the patients received special therapeutic nutrition. Conclusions: Patients with rapid disease progression have a short period of ALS diagnosis and rapidly increasing nutritional disorders, reflected in higher rates of losing weight and skeletal muscle mass. However, patients with rapid diagnosis of the disease had the lowest level of nutritional support. Lack of time to make the difficult decision to insert a gastrostomy tube and perform the necessary preoperative examination is the main reason for the low rate of gastrostomy tube placement in patients with rapidly progressing disease. In this regard, the development of new measures and algorithms for dynamic monitoring of the nutritional status of patients with ALS, as well as increasing awareness of the need for timely gastrostomy, is required. Bioimpedance analysis of body composition can be one of the methods for monitoring the patient’s nutritional status, allowing one to assess the dynamics of decrease in skeletal muscle mass as the most labile component of body composition in patients with ALS.

Abstract B025: Surveillance outcome in individuals at high risk of pancreatic cancer

Abstract INTRODUCTION: Pancreatic ductal adenocarcinoma (PDAC) has a poor 5-year survival rate. PDAC surveillance is recommended in high-risk individuals (HRIs) with strong PDAC family history or a pathogenic germline variant (PGV) in a PDAC susceptibility gene. We aimed to explore a potential correlation between genetic status, extent of family history, pancreatic findings, and surveillance implications in heterogeneous PDAC HRIs. METHODS: from January 2015 up to date, a total of 340 HRIs from 291 families visited our pancreatic cancer high-risk clinic. Surveillance included annual clinic visits, EUS/MRI imaging, genetic and laboratory blood testing. Participants completed a questionnaire that included personal and familial medical history, dietary habits, daily activities with emphasis on smoking habits, alcohol use, and physical activity. RESULTS: Our cohort was divided into 3 groups: familial pancreatic cancer that include individuals with family history of 2 or more first degree family (FDR) with PDAC (FPC; 96 individuals), familial non-FPC, families with at least 2 biological relatives with PDAC and not meeting FPC criteria, (119 individuals), and hereditary pancreatic cancer (PC), individuals with PGV in a PC susceptibility gene and a family member with PDAC carrying the same PGV (124 individuals). The cohort average age at first visit was 54 years with 44% male and 56% female ratio. Seventy percent of the cohort was of Jewish Ashkenazi decent. Genetic testing was performed in several steps, first BRCA1/2 founder mutations was performed in all individuals followed by genetic panels and whole exome sequencing (WES). PGVs were detected in 36.4% of all families. There was no significant difference in the genetic finding between the FPC and non-FPC groups (11% and 9.6% respectively). Of the study cohort 35% were screened by EUS and 8% by MRI/MRCP. Pancreatic lesions detected included 11 cases of new PDAC (3.2%), 69 cystic lesions (20.3%), 43 cases early chronic pancreatitis (12.6%) and 11 cases of main pancreatic duct dilation (3.2%). To better understand the risk of PDAC development in HRIs we recently added a novel cell-free chromatin blood test for early cancer detection (in collaboration with SENSEERA, Israel) and compared it to EUS imaging results. The test provides multidimensional epigenetic information that sheds light on the identity and the transcriptional state of the cells that are dying in the body of the patient. Our preliminary results show nice separation between the healthy control and PC groups. PC HRIs show slight increase in score compared to the general population while individuals with worrisome features show substantial increase compared to HRIs with no EUS findings. DISCUSSION: Surveillance seems effective for detection of early-stage PDAC and precursor lesions. However, screening strategy can be improved by adding newer modalities like chromatin-based tests that might help to further define the risk of cancer development in HRIs.

Surgery do save life in cervical spinal injury: 5 years study of a tertiary care in East Java, Indonesia

Cervical spine has the most movement in spine therefore it has high risk of injury which may involve vertebrae, soft tissue and spinal cord. Trauma to cervical has highest risk of neurologic deficits due to spinal cord injury (SCI) causing high number of morbidity and mortality. Retrospective study was conducted with descriptive-analytic design by total sampling of cervical spinal injury patients in Dr. Soetomo General Academic Hospital from January 2018 to June 2023. Patient demographic and survival analysis of patients was described using Kaplan-Meier chart and logistic regression test to find factors contributing to patients’ survival. Gender, age, mechanism of injury, surgical approach, duration, intra-operative bleeding, lesion level, time to surgery, and initial blood laboratory had no significant impact while neurological status and operative treatment have significant survival probability. Patients with American Spinal Injury Association Impairment Scale (AIS) A score have lower survival rate which associated with respiratory muscle weakness, cardiovascular and autonomic nervous system dysfunction. Any unstable cervical fracture is advised for surgery while decompression surgery is recommended for improving outcome and ease of rehabilitation. Clinical implication of this study recommends surgery for cervical spinal injury with 5.6 times more chance of survival than non-operative patients. Initial AIS neurological status and surgery performed contributes to survival. Level of cervical lesion, age, gender, mechanism of injury, surgical approach, duration, blood laboratory tests do not have a significant impact on survival while fastest time admission to surgery does not reflect higher chance of survival probability.

Analysis of rehabilitation of individuals after cholecystectomy in sanatorium-resort conditions as a prerequisite for the development of the concept of physical therapy

Laparoscopic cholecystectomy (LCС) is the most commonly performed surgical intervention. The presence of diseases of several body systems in individuals may indicate metabolic syndrome. The consequences of cholecystectomy are manifested by various symptoms and are generally called postcholecystectomy syndrome. The purpose of the article is to analyze the methods and means of rehabilitation of patients after LCC at the sanatorium stage on the example of the functioning of the Department "Lavanda Sanatorium" of CJSC "Ukrprofozdorovnytsia" of the sanatorium-resort complex "Morshynkurort". Research methods: analysis and synthesis of scientific and methodological literature, analysis of methods and means of rehabilitation of patients after LCC for one calendar year. A total of 1296 people diagnosed with gallbladder and biliary tract diseases received rehabilitation services, including those after LCC. Patients undergoing rehabilitation in the post-acute and long-term stages after surgical interventions are treated at the Lavanda Sanatorium department. The treatment period is from 18-24 days at the patient's request. The criteria for the quality of rehabilitation services were as follows: improvement of health, disappearance of pain, dyspeptic phenomena, increased appetite, normalization of bowel movements, normalization of instrumental and laboratory blood tests, etc. Patients after LCC have signs of metabolic and postcholecystectomy syndromes. In addition to the dysfunction of the gastrointestinal tract, there are also limitations of other various body systems, their functions, activities and participation. Therefore, it is necessary to use the international assessment tool "International Classification of Functioning and Participation" and, according to the established disorders, to set individual rehabilitation goals for patients. The use of mineral therapeutic water from well No. 3 in the village of Horishne, Stryi district, Lviv region, in a dilution of 3.0-3.4 g/dm3 on the functional state of the liver of patients after LCC in the conditions of the Morshynkurort sanatorium-resort complex leads to an improvement in liver function, which is confirmed by the results of biochemical studies of patients' blood. Conclusions. Preformed physical factors (physical procedures), heat therapy, various baths, mud therapy, reflexology, microclysters, exercise therapy and massage are traditionally the most popular in the prescription department. However, the use of such remedies, in addition to the use of mineral healing water, is a matter of great debate among the professional community and requires more detailed study in terms of evidence-based practice in health care.

Feline leishmaniosis in the Mediterranean Basin: a multicenter study

BackgroundCats are now recognized as competent hosts for Leishmania infantum and a blood source for sand fly vectors. Although canine leishmaniosis (CanL) is endemic in Mediterranean Basin countries, large-scale epidemiological studies are lacking for feline leishmaniosis (FeL). This study aimed to assess the prevalence of L. infantum infections, associated risk factors, clinical signs, and clinicopathological abnormalities in domestic cat populations from six Mediterranean Basin countries.MethodsFrom 2019 to 2022, blood and serum samples of cats (n = 2067) living in Italy (n = 300), Greece (n = 297), Portugal (n = 295), France (n = 231), Israel (n = 313), and Spain (n = 631) were collected along with animal data (i.e., age, sex, breed, housing conditions, and geographical origin), clinical signs, and laboratory blood test parameters. Cats were grouped according to their age as kittens (up to 1 year), young (older than 1 and younger than 7 years), mature (between 7 and 10 years), and senior (older than 10 years). Serum samples were tested for L. infantum by immunofluorescence antibody test (IFAT) and enzyme-linked immunosorbent assay (ELISA), and blood samples of seropositive cats were tested for L. infantum kinetoplast deoxyribonucleic acid (kDNA). Viral infection by feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV) was molecularly addressed in all cats enrolled. Statistical analysis was performed to evaluate the association between the risk of L. infantum infection and independent variables, and among co-infection of L. infantum with FIV and/or FeLV, clinical signs, and clinicopathological abnormalities.ResultsOverall, 17.3% (358/2067) of cats scored positive for L. infantum by serological tests. Specifically, 24.7% were from Portugal, 23.2% from Greece, 16.6% from Israel, 15% from Spain, 13.3% from France, and 12.6% from Italy. Leishmania infantum DNA was detected in 15 seropositive animals. Housing condition and FIV infection proved to be risk factors for FeL. Leishmania seropositivity was significantly associated with weight loss, lymphadenomegaly, gingivostomatitis, and oral ulcers, as well as with reduced albumin and albumin/globulin ratio, increased total globulins and total proteins, leukocytosis, and thrombocytosis.ConclusionsThis study provides, for the first time, a large-scale epidemiological survey on FeL and its clinical presentation, revealing that L. infantum circulates among domestic cats, especially shelter/free-roaming and FIV-infected animals, living in CanL endemic countries of the Mediterranean Basin.Graphical
