Severe acute pancreatitis (SAP) is associated with metabolic disorders, hypocalcemia, and multiple organ failure. The objective of this study was to investigate changes in thyroid ultrastructure and function in rats with SAP and to provide a theoretical basis for the clinical treatment of thyroid injury in patients with SAP. 64 male SPF Wistar rats were randomly divided into the SAP group and the control group. Pancreatic enzymatic indicators and thyroid hormones were detected, pathology scores were evaluated, and morphological changes were observed under light microscopy and transmission electron microscopy (TEM) in both groups. The serum levels of triiodothyronine (T3), tetraiodothyronine (T4) and Ca2+ were significantly lower in the SAP group than in the control group (P<0.05), whereas the level of calcitonin (CT) was significantly higher than that in the control group (P<0.05). The thyroid structure (pathology and electron microscopy) of the SAP rats was seriously damaged and worsened over time. SAP can cause thyroid injury through a variety of mechanisms, which can also retroact to pancreatitis to aggravate the inflammatory response. This study may have theoretical significance for basic research on SAP. Key words Severe acute pancreatitis, Thyroid, Structure and functional changes, Transmission electron microscopy.

OBJECTIVE: To present a case of a patient who developed acute Sheehan's syndrome, despite adequate estimated blood loss. CASE REPORT: Sheehan's syndrome is a relatively rare disease with various incidences, mainly due to different obstetric care factors in individual countries. Pathogenetic mechanisms are not fully understood. An important factor is reduced blood flow through the pituitary arteries caused by hypotension in the setting of postpartum hemorrhage. Subsequent clinical manifestations depend on the extent of damage to the pituitary gland, and consequently, on the loss of individual hormones, the secretion of which is controlled by the pituitary gland. Most patients are diagnosed years later. Our case describes a patient with Sheehan's syndrome that developed in the early postpartum period. The patient was successfully diagnosed and adequate replacement therapy was started. CONCLUSION: In summary, acute Sheehan's syndrome is a rare occurrence. Agalactia, amenorrhea, fatigue, and other non-specific symptoms should be considered despite its rarity.

BACKGROUND: Diarrhoea remains a leading cause of death in children. An intestinal adsorbent may reduce diarrhoea duration and severity. METHODS: Randomised controlled feasibility trial with two phases: phase 1 (0-4 hours and double-blind) and phase 2 (up to 5 days and open-label). 50 children aged 6-59 months with acute diarrhoea presenting with no or some dehydration to the emergency paediatric unit and outpatient clinic at Edward Francis Small Teaching Hospital, Banjul, The Gambia were randomised to either standard treatment (oral rehydration fluid and zinc) or standard treatment with polymethylsiloxane polyhydrate for up to 5 days. RESULTS: Recruitment was completed in 7 months. All but one child completed the study. There were no major protocol deviations although patient-held diaries did not collect reliable information. Time from randomisation to the last watery stool (primary outcome) was shorter in the intervention than control arm (mean difference -19.3 hours, 95% CI -30.9 to -7.8). Stool frequency was lower in the intervention arm on days 2 (95% CI -0.8 to -1.3 to -0.3) and 3 (95% CI -0.8; -1.3 to -0.3). One serious event (death) occurred in the control arm. CONCLUSIONS: A randomised, controlled trial is feasible. Further clinical trials are warranted to confirm the efficacy of polymethylsiloxane polyhydrate in acute diarrhoea and inform management guidelines. TRIAL REGISTRATION NUMBER: PACTR202302683128875.

Acute mesenteric ischaemia (AMI) is a sudden onset of impaired bowel perfusion. Has a high mortality rate and is difficult to diagnose. Therapy involves endovascular, surgical, or a combination of both. Because of baseline differences, the comparison between endovascular and open surgical treatment is subject to selection bias. The aim of this study was to evaluate the results of treatment of AMI by open or endovascular approach in combination with laparotomy, and evaluation of treatment strategy in similar situations. Clinical data from 21 patients treated for AMI between 2018 and 2022 were retrospectively reviewed and compared. The primary endpoint of the study was in-hospital mortality. The secondary endpoint was the statistical evaluation of risk factors for mortality. All patients underwent acute endovascular revascularisation. Aspiration thromboembolectomy was performed in nine patients, stenting in seven, PTA in one and surgery in three. Endovascular therapy was unsuccessful for technical reasons in 3 patients. None of the monitored parameters reached statistical significance. The best results were achieved in the early diagnosis group. The overall mortality of acute mesenteric ischaemia in our cohort was 34.8%. Acute mesenteric ischaemia is a serious condition affecting mainly elderly patients with a high mortality rate, but the diagnosis of mesenteric ischaemia is not an automatic death sentence. To achieve the best therapeutic outcome, mesenteric ischaemia needs to be diagnosed and treated at an early stage. The best therapeutic outcomes are achieved in centres with 24-hour access to endovascular revascularisation and surgical therapy.

INTRODUCTION: Atrial fibrillation (AF) can cause or aggravate heart failure (HF). Catheter ablation (CA) is an effective treatment for AF. This study focused on the feasibility and outcomes of emergent AF ablation performed during hospitalization for acute HF. METHODS AND RESULTS: We retrospectively investigated patients who underwent emergent CA for AF during hospitalization for acute HF in 2018-2024. Arrhythmia recurrence was the primary endpoint. The combination of arrhythmia recurrence, HF hospitalization, and all-cause death was the secondary endpoint. Patients were censored 1 year after the index procedure. We included 46 patients, 35% females, with median age of 67 [interquartile rage: 61, 72] years and left ventricular ejection fraction (LVEF) of 25 [23, 28]%. Thermal CA was performed in 14 patients, and pulsed field ablation (PFA) in 32 patients. Procedure time was significantly shorter with PFA compared to thermal CA (77 [57, 91] vs. 166 [142, 200] minutes, p < 0.001). Fluoroscopy time was longer with PFA (9.5 [7.6, 12.0] vs. 3.9 [2.9, 6.0] minutes, p < 0.001), with a borderline trend towards higher radiation dose (75 [53, 170] vs. 50 [30, 94] μGy.m2, p = 0.056). Extrapulmonary ablation was frequent (86% and 84% for thermal CA and PFA, p > 0.9). The estimated freedom from the primary endpoint was 79% after PFA and 64% after thermal CA (p = 0.44). The estimated freedom from the secondary endpoint was 76% after PFA and 57% after thermal CA (p = 0.43). LVEF improved by 24% ± 2% (p < 0.001) in patients with the first manifestation of HF and by 14% ± 4% (p = .004) in patients with decompensated HF diagnosed earlier. CONCLUSIONS: Emergent CA of AF during acute HF hospitalization is safe and associated with improved LVEF and good clinical outcomes. In the PFA era, the rate of these procedures is progressively increasing as they are readily available and easy to perform compared to thermal ablation.

Recurrent acute otitis media (rAOM) poses a significant challenge in children aged 1 to 6 years, characterized by frequent and treatment-resistant ear infections. While existing studies predominantly focus on alterations in the nasopharyngeal microbiome associated with rAOM, our research explores the understudied association with the gut microbiome. In this cross-sectional observational prospective study, we enrolled 35 children aged 1 to 6 years during the 2021/2022 cold season. The test group comprised children with rAOM (n = 16), and the control group consisted of generally healthy children (n = 19). Samples (stool and nasopharyngeal swabs) were collected in late spring to ensure an antibiotic-free period. Detailed metadata was gathered through a questionnaire examining factors potentially influencing microbiota. Microbiota composition was assessed through amplicon sequencing of the V3-V4 region of the 16S rRNA gene. Our findings revealed limited alterations in gut microbiota composition among children with rAOM compared to healthy controls. Six bacterial taxa (Veillonella, Lachnospiraceae, Ruminococcaceae, Lachnospiraceae, Bacteroides and Blautia) were differentially represented with weak statistical significance. However, several bacterial taxa displayed correlations with multiple consecutive infections, with Turicibacter showing the most significant association. Additionally, day care centre attendance emerged as a potent gut microbiota modifier, independent of rAOM. Although our study identified limited differences in gut microbiota composition between children with rAOM and healthy controls, the observed correlations between the number of infections and specific bacterial taxa suggest a potential link between rAOM and the gut microbiota, warranting further investigation.

Fluid collections are common manifestations of local complications of acute pancreatitis (AP). The determination of fluid collections is important in stratifying the severity of the course of acute pancreatitis and choosing the appropriate management. In this study, the frequency of detection of fluid effusions by various instrumental methods and their clinical significance in 677 patient was assessed, taking into account the severity of the course of AP and anatomical localization of fluid accumulations. The computed tomography (CT) method showed its advantage in detecting fluid effusions in the pleural cavities, while the ultrasound method showed its indisputable significant advantage in the diagnosis of fluid effusions located parapancreatically and in the lesser sac: the highest frequency of detection of fluid effusion was in 65.3% of all patients in the general group using CT compared to 39% using ultrasound and 12.5% using chest X-ray (p<0.05). Each of the above methods showed different sensitivity depending on the anatomical areas of fluid effusion detection. In particular, the CT method revealed the presence of fluid in the pleural cavities in 50.7% of the total group, in the abdominal cavity in 36.0% of cases, and only in 8.0% of cases in the parapancreatic or lesser sac. The opposite picture was revealed when using the ultrasound method, in which fluid was found in the parapancreatic/lesser sac in the largest number of cases - 28.1%, in the abdominal cavity - in 22.6% of cases, and in the pleural cavity - in 14.3% of cases.

Referrals to emergency services are frequently made for acute appendicitis and renal colic. This conundrum of patients with acute appendicitis and right ureteral stones frequently presents itself to emergency physicians. The hematological parameters of patients suffering from acute appendicitis and right ureteral stones were compared in this study. From May 2022 to April 2023 the patients who applied to emergency department were reviewed retrospectively. Of these patients, age, sex, complete blood test results including white blood cell, procalcitonin and C-reactive protein were recorded. The platelet to lymphocyte ratio and the neutrophil to lymphocyte ratio were calculated by dividing the platelet count by the lymphocyte, and the neutrophil count by the lymphocyte count, respectively. We used the receiver operating characteristic curves to assess the diagnostic efficacy of hematological markers. There were 106 patients in the study. The mean age of the patients was 43.83 ± 15.82 years. The significant difference was found for age, white blood cell, neutrophil, lymphocyte, neutrophil to lymphocyte ratio, platelet to lymphocyte ratio and monocyte between groups. The white blood cell and neutrophil to lymphocyte ratio have the biggest area than the other parameters in the receiver operating characteristic curves. Patients with acute appendicitis have a high level of neutrophil to lymphocyte ratio, platelet to lymphocyte ratio than ureteral stones. Further studies are needed to define the diagnostic efficacy of hematological markers for acute appendicitis and ureteral stones.

Acute cellular rejection (ACR) frequently occurs following lung transplantation (LuTx) and represents a risk factor for the development of chronic lung allograft dysfunction (CLAD) as well as long-term survival. The histopathological diagnosis of ACR carries a burden of interobserver variability. The widespread utilization and cost-effectiveness of immunohistochemistry (IHC) was proven beneficial in diagnosing rejection in human kidney transplantations and LuTx rat models. However, its potential for ACR detection in patients remains unexplored. We analyzed surface markers (CD3, CD4, CD8, CD20, CD68, CD47, PD-1, PD-L1, and CD31/PECAM-1) on lung tissue cryobiopsy samples collected within 6 months post-LuTx from 60 LuTx recipients, 48 of whom were diagnosed with ACR. Additionally, serum samples from 51 patients were analyzed using a multiplex bead-based Luminex assay. The cytokines and markers included PD-L1, IL2, TNFα, IFNγ, and Granzyme B. We observed a significant increase in PD-L1 tissue expression within the rejection group, suggesting a concerted effort to suppress immune responses, especially those mediated by T-cells. Furthermore, we noted significant differences in PECAM-1 levels between ACR/non-ACR. Additionally, peripheral blood C-reactive-protein levels tended to be higher in the ACR group, while Luminex serum analyses did not reveal any significant differences between groups. In conclusion, our findings suggest the potential value of PECAM-1 and PD-L1 markers in diagnosing ACR.

This is an overview of relation between acute and chronic pancreatitis and between acute pancreatitis and pancreatic cancer. Acute pancreatitis and recurrent acute pancreatitis are an etiological factor of chronic pancreatitis. Population-based studies have calculated the risk of acute recurrent pancreatitis after the first attack of acute pancreatitis to be 20% and development of chronic pancreatitis after first attack of acute pancreatitis is 10%. An important risk factor is tobacco smoking. Acute and chronic pancreatitis are risk factors for pancreatic cancer. The risk of acute pancreatitis is related to the number of recurrences of acute pancreatitis, but not the etiology of acute pancreatitis. Acute pancreatitis, as well as chronic pancreatitis, are risk factors for pancreatic cancer. After an attack of acute pancreatitis or recurrent acute pancreatitis a patient should be regarded as a high risk.
