Multiparametric assessment of decongestion in patients admitted with acute heart failure: dynamic changes and correlation with natriuresis

Abstract Background Heart Failure (HF) is a major public health problem, expected to increase in the next few decades. The vast majority of acute HF (AHF) episodes are precipitated by congestion with volume overload and/or fluid redistribution. Current Guidelines stress on the importance of relieving congestion before discharge, recommending anyway only daily assessment of signs and symptoms. Lung ultrasound (LUS) B-lines and other ultrasound markers of congestion has emerged as valuable tools to improve diagnostic accuracy and help clinicians in fluid management. Purpose To assess the dynamic changes of B-lines and other markers of congestion and their relationship with the clinical evaluation, chest X-ray (CXR) and natriuretic peptides in patients admitted for AHF. Methods Fifty-eight patients (age 72±11 ys, 35% women) admitted with acute HF were enrolled. Patients underwent clinical evaluation (Clinical Congestion Score, CCS, including rales, pathological S3 heart sound, pedal oedema, jugular vein distension; range 0-4), and CXR (CXR score, including enlargement and loss of definition of hilar structures, peribronchial and perivascular cuffing, cardiomegaly, pleural effusion; range 0-4). An integrated multiorgan ultrasound exam including LUS B-lines, echocardiography, and venous excess ultrasound (VExUS) score was performed at admission (T0), between 24 and 48 hours from T0 (T1), and at discharge (T2). Follow-up data at 30 days were collected. Results Mean CCS was 1.52±0.99 at T0, with a reduction at T1 (0.86±0.66; p<0.01), and at T2 (0.34±0.66; p<0.01). Sixteen percent of patients with a CCS=0 at T0 showed, however, persistent B-lines on LUS (mean B-lines 19±6). The mean number of B-lines was 26±12 at T0 with a reduction at T1 (17±11; p<0.001), and at T2 (13±11; p<0.001). Other echocardiographic non-invasive hemodynamic parameters, such as pulmonary artery systolic pressure (PASP) and E/e’ showed a reduction only at T2, but not at T1 (figure). The number of B-lines correlated at all time points with CCS, CXR score, VExUS score, and NT-proBNP values (all p<0.05). We divided patients into two groups: "responders" (with ≥15 reduction of B-lines between T0 and T2) and "non-responders" (with <15 reduction of B-lines between T0 and T2). Responders had higher chlorine and sodium urinary excretion at T1 compared to non-responders. The number of B-lines at all time points was associated to 30-days cardiovascular mortality at univariable analysis. Neither CCS nor CXR score were associated with 30-day events. Conclusions In patients with acute HF, B-lines quantification is related to standard congestion assessment based on clinical evaluation, CXR and NT-proBNP, showing, however, a more dynamic behaviour in the assessment of decongestion. B-lines variations are also related to diuresis and chlorine urinary output, a recognized predictor of diuretic response. Persistent congestion is related to an increased risk of hospitalization and death.

Development and validation of a predicting model for risk of rehospitalization within 30 days in heart failure patients with preserved ejection fraction

Abstract Objective This study aimed to develop and validate a predicting model for risk of rehospitalization within 30 days post discharge in patients diagnosed with Heart Failure with Preserved Ejection Fraction (HFpEF). Methods Clinical data of 9555 HFpEF patients registered in the heart failure registry from 2014 to 2022 at our hospital were analyzed. A total of 8160 patients (from 2014-2021) were designated as the training set, and 1395 patients (from 2022) as the validation set. A predictive model was established based on risk factors associated with 30-day rehospitalization due to heart failure identified by the Least Absolute Shrinkage and Selection Operator (LASSO) regression and logistic regression analysis. The model's stability was ensured through Bootstrap internal validation and Temporal validation external validation. Results LASSO and logistic regression analyses identified eight risk factors associated with increased risk of 30-day rehospitalization, including New York Heart Association (NYHA) classification, albumin, c-reactive protein, N-terminal pro b-type natriuretic peptide (NT-proBNP) divided by 100, anemia, pleural effusion, atrial fibrillation, and pulmonary hypertension. The established predictive model demonstrated good discriminative ability in the internal validation with an Area Under the Curve (AUC) value of 0.714, and a 95% confidence interval (CI) of 0.693-0.736 after 500 Bootstrap replicates. In the Temporal validation external validation, the model exhibited robust stability with an AUC value of 0.740 and a 95% CI of 0.693-0.781. When compared to analogous models from prior studies, present model showcased superior predictive accuracy in that both Net Reclassification Improvement (NRI) and Integrated Discrimination Improvement (IDI) values were positive and within their respective 95% confidence intervals (P-values <0.05). Conclusion This study successfully developed and validated a predictive model for 30-day rehospitalization due to heart failure in patients diagnosed with HFpEF. This model might allow the timely identification of high-risk HFpEF patients for 30-day rehospitalization due to heart failure and optimizes the patient management accordingly.

Efficacy and safety of ambulatory, weekly, high-intensity intravenous diuretic strategy for congestion-refractory heart failure patients: insights from the DEA-HF prospective randomized clinical trial

Abstract Background Congestion and volume overload are strongly associated with low quality of life and pose a significant risk for both rehospitalization and mortality in heart failure (HF) patients. Despite the widespread use of diuretics in HF, the use of weekly, intravenous (IV), high-intensity diuretic treatment has not been prospectively studied in the setting of ambulatory congestion-refractory patients. Purpose To assess the efficacy and safety of weekly high-intensity diuresis regimens in a practical setting of ambulatory day care for chronically congested HF patients. Methods We performed a sub-analysis on data from a prospective, randomized, cross-over controlled study (DEA-HF) originally designed to compare diuresis regimens in the setting of an HF ambulatory daycare unit who had signs of congestion or volume overload despite adherence to guideline-directed medical therapy. Each patient received three different IV diuretic regimens, in one of six randomized sequences: IV furosemide 250mg; IV furosemide 250mg + oral metolazone 5mg; and IV furosemide 250mg + IV acetazolamide 500mg. All regimens given on the same chronological week were pooled, and diuresis efficacy was assessed by measuring excreted urine volume and sodium weight 6 hours post treatment initiation. Additional assessment at one week post each treatment included serum levels of NT-ProBNP, body weight and creatinine as well as congestion score based on the presence of ascites, pleural effusion and pedal edema. Statistical analysis was based on linear mixed models while accounting for the random effect of patient identity. Results A total of 42 patients were recruited. The mean age was 72±9 years, twenty-one subjects (50%) had LVEF ≥ 50%. 74% of patients were NYHA III class. All patients were on contemporary guidelines-directed HF therapy. Analysis of excreted sodium weight and urine volume revealed values of 4202.1±180.1 mg (Mean±SEM) and 1.77±0.07 liter per visit, respectively. No significant differences in efficacy were detected among treatments given in consecutive weeks (P= 0.80 and 0.69 for differences in sodium weight and urine volume, respectively). After 4 weeks, log(NT-ProBNP) was significantly decreased (P=0.044), accompanied by a significant decrease of 2.4±0.62 kg in body weight (P=0.0004) and of 0.92±0.44 points in congestion score (P=0.037). Serum creatinine level was only slightly increased by 0.19±0.04 mg/dl (P=0.0001), demonstrating the overall safety of the high-intensity diuresis strategy. Conclusions In ambulatory, congestion refractory HF patients a strategy based on high-intensity, weekly diuresis therapy was safe and effective for three consecutive weeks. The natriuresis response to the treatments was maintained, NT-ProBNP levels and congestion score were decreased. The strategy may be instrumental for ambulatory HF patients that require diuretic therapy intensification and may allow to prevent hospitalization.

Glutathione s-transferase pi is a marker of loop diuretic resistance in patients with congestive heart failure exacerbation

Abstract Background Loop diuretic resistance (LDR) in patients with heart failure (HF) exacerbation is associated with worse clinical outcomes, greater symptom burden and mortality. Diagnosis and treatment of LDR remains a significant clinical dilemma. Purpose To assess the ability of different urine biomarkers to predict LDR in patients with HF exacerbation. Methods Consecutive patients with congestive HF exacerbation were prospectively included in the study. HF was diagnosed according to ESC 2021 HF Guidelines definition. Congestion was defined as a presence of one or more of the following signs: edema, ascites, pleural effusion. LDR was defined as persistent congestion on the 4th day of hospital stay despite high i.v. loop diuretic dose. Urine biomarkers released from different parts of the nephron (Kidney Injury Molecule-1 - KIM-1, N-acetyl-β-D-glucosaminidase - NAG, uromodulin, glutathione S-transferase Pi - pi-GST, aquaporin-2), transthoracic echo, clinical and biochemical parameters were evaluated on the 1st and 4th day of hospital stay. Results are presented as mean ±standard deviation or median (interquartile range). Results 40 patients were included in the study with median age 84 (72,8; 86) years, median left ventricle ejection fraction (EF) 35.3 (26,5; 49) %, median NT-proBNP 8967.5 (3024; 15241) pg/ml. LDR was found in 14 (35%) patients. Univariate analysis identified the following risk factors for LDR: urine pi-GST concentration on admission and on the 4th day, right ventricle to pulmonary circulation coupling index (TAPSE/PASP ratio), presence of mitral regurgitation, serum creatine concentration, serum urea concentration, serum LDL concentration. Logistic regression analysis identified pi-GST concentration as a significant independent risk factor for LDR in this population: odds ratio (OR) 5.75 [95% confidence interval (CI) 1.271–25.990]. Conclusions Urine pi-GST on admission and after 4 days of treatment might be a marker for a development of LDR in patients with congestive HF exacerbation.

Risk factors of all-cause mortality in heart failure with mildly reduced ejection fraction patients with different post-discharge left ventricular ejection fraction variation patterns

Abstract Background The identification of risk factors for all-cause mortality in patients diagnosed with heart failure with mildly reduced ejection fraction (HFmrEF) and exhibiting varying post-discharge left ventricular ejection fraction (LVEF) patterns remains incomplete. This study aimed to determine the independent risk factors of all-cause mortality among HFmrEF patients with different LVEF variation patterns post-discharge. Methods This retrospective study analyzed data from 807 HFmrEF patients admitted to our hospital between January 2015 and August 2020. Patients were categorized into three groups based on LVEF variation patterns within 6 months to one year post-discharge: Group A (transitioning to heart failure with reduced ejection fraction [HFrEF], n=225), Group B (remaining as HFmrEF, n=335), and Group C (reverting to heart failure with preserved ejection fraction [HFpEF], n=227). Patients were followed up for a mean of 33 months, with all-cause mortality as the primary endpoint. Multivariate Cox regression analysis was conducted to identify independent risk factors for all-cause mortality in each group. Results The mortality rates for Groups A, B, and C were 43.11%, 23.94%, and 24.67%, respectively (P<0.001). Independent risk factors for all-cause mortality in Group A included age (HR=1.04, P=0.007), obesity (HR=1.76, P=0.040), higher creatinine (>100 µmol/L, HR=1.83, P=0.029), higher E/e’ (HR=1.06, P=0.001), absence of PCI (HR=0.51, P=0.019), and non-use of ACEI/ARB (HR=0.039, P=0.006). In Group B, independent risk factors for all-cause mortality were age (HR=1.06, P<0.001), higher NT-proBNP (>2505 pg/ml, HR=2.50, P=0.002), and absence of PCI (HR=0.040, P=0.005). Group C exhibited age (HR=1.04, P=0.002), pleural effusion (HR=2.38, P=0.007), higher creatinine (>100 µmol/L, HR=2.84, P<0.001), and non-use of ACEI/ARB (HR=0.42, P=0.021) as significant independent risk factors associated with increased all-cause mortality risk. Conclusion This study highlights distinct risk factors associated with all-cause mortality in HFmrEF patients exhibiting different post-discharge LVEF variation patterns. Age emerged as a consistent risk factor across all groups, underscoring the importance of age-related considerations in managing HFmrEF patients. Additionally, factors such as obesity, renal function, echocardiographic parameters, and medication adherence played varying roles in influencing mortality risk depending on the evolution of LVEF following discharge. These findings emphasize the need for personalized risk stratification and tailored management strategies for HFmrEF patients to improve outcomes and reduce mortality rates.

Decortication with uniport video-assisted thoracoscopic surgery for empyema due to postoperative esophageal leakage: a report of two pediatric cases

BackgroundVideo-assisted thoracoscopic surgery (VATS) is considered useful for the treatment of parapneumonic empyema in children. However, thoracoscopic management of empyema due to esophageal leakage as an operative complication has not been well described in the literature.Case presentationWe successfully decorticated severe empyema using uniport VATS in 2 children (a 2-year-old boy who suffered esophageal perforation after laparoscopic anti-reflux surgery, and a 7-month-old girl who had anastomotic leakage after thoracoscopic repair of esophageal atresia). In these patients, we noticed that pleural effusion rapidly progressed to empyema and caused respiratory insufficiency due to wide-range coverage by fibrotic pleural rind that was successfully decorticated under video-assisted vision from a mini-thoracotomy, followed by spontaneous healing of the leakage.ConclusionsWe did not attempt to closely approach or try to repair the esophageal leakage. We believe that this is an important tip for these situations.

Early result of minimally invasive cardiac myxoma resection at University Medical Center, Ho Chi Minh City

Objective: The study aimed to evaluate various clinical and paraclinical characteristics, as well as early surgical outcomes of minimally invasive cardiac myxoma resection at University Medical Center HCMC. Subjects and methods: This is a retrospective descriptive case series study involving all patients diagnosed with cardiac myxomas who underwent minimally invasive surgery at University Medical Center HCMC from January 2020 to June 2024. Results: There were 31 patients, consisting of 22 females and 9 males. The mean age was 56,2 ± 10,7 years old (from 37 to 77 years old). The clinical manifestations were diverse: asymptomatic (45,2%), cerebral embolism (6,4%), fatigue (29,0%), dyspnea (35,5%), palpitations (12,9%), and dizziness (12,9%). Echocardiographic results: 90,3% left atrial myxoma, 9,7% right atrial myxoma. The tumor attachment sites: interatrial septum (93,6%), left atrial wall (6,4%). The average tumor size was 36,3 ± 15,1 mm. All tumors were completely resected (100%). Additional surgical procedures: mitral valve repair (3,2%), interatrial septum repair (6,4%). Cardiopulmonary bypass time was 82,4 ± 31,1 minutes (from 49 to 199 minutes), cross - clamp time was 39,2 ± 17,6 minutes (from 18 to 85 minutes), with 3 cases not requiring cardiac arrest. Ventilation time was 13,2 ± 6,3 hours (from 6,7 to 32,4 hours), intensive care unit stay was 52,6 ± 28,1 hours (from 13 to 113,7 hours), postoperative recovery time was 6,9 ± 2,3 days (from 4 to 16 days). Early outcomes: 3 cases of atrial fibrillation with rapid ventricular response, treated medically (9,7%), 1 case of acute kidney injury (3,2%), 4 cases of pleural effusion (12,9%), 3 cases of pneumothorax (9,7%), 1 case of right external iliac artery thrombosis requiring surgical thrombectomy (3,2%), and 2 cases of deep vein thrombosis (6,4%). No surgical site infections, cerebrovascular accidents, or mortality within 30 days post-surgery were reported. Conclusion: Minimally invasive cardiac myxoma resection demonstrates a low complication rate, with no reported tumor recurrence or early postoperative mortality. This technique offers a safe and effective alternative to traditional median sternotomy and may be gradually adopted and implemented in lower - level healthcare facilities.

Optimal anticoagulation strategy for left ventricular assist device patients undergoing thoracentesis: a retrospective study

Abstract Background Left ventricular assist devices (LVADs) are associated with thromboembolic risks necessitating anticoagulation, yet balancing these risks with bleeding concerns remains challenging. Current practice involves warfarin with a target INR of 2-3 alongside anti-platelet therapy. However, consensus on anticoagulation management is lacking, particularly during sub-therapeutic INR or procedural settings. Common strategies include bridging anticoagulation with heparin or enoxaparin, temporary cessation of anticoagulation during the procedure or uninterrupted anticoagulation. Purpose To evaluate and compare the incidence of bleeding and thromboembolic events in LVAD patients undergoing thoracentesis, with a focus on determining the optimal anticoagulation strategy during procedures. Methods Retrospective data was collected over one year from LVAD patients undergoing thoracentesis at a large academic center. Patients were categorized into ‘bridge’ (received intravenous heparin for bridging during thoracentesis) and ‘no-bridge’ (did not receive bridging anticoagulation) groups. Warfarin was paused before procedure and resumed after procedure in both groups. Baseline characteristics, including age, sex, race, BMI, LVAD type, and INTERMACS profile, were recorded. Primary outcomes were major bleeding and thromboembolic events within 30 days of warfarin cessation. Statistical analysis used t-test/Wilcoxon for continuous variables and Chi-square/Fisher exact test for categorical variables. A p-value <0.05 was considered significant. Results During the study, twenty LVAD patients underwent thirty-two thoracenteses (nineteen bridge, thirteen no-bridge). The demographics were similar among the two groups. Warfarin was held for an average of 5.5 ± 4.6 days before and resumed 4.1 ± 4.6 days after the procedure in the bridge group and 3.8± 3.2 days before and 1.7 ± 2.5 days after in the no-bridge group. Major bleeding occurred in 73.7% of bridge group cases versus 30.8% of no-bridge group cases (p=0.059). 63.2% of bridge group patients had a bloody pleural effusion on thoracentesis compared to 46.2% of no-bridge group patients (p value= 0.34). Average transfusion requirements were 2.8 units and 2 units in the bridge and the no-bridge groups respectively (p=0.658). Thromboembolic events included a 10.5% ischemic CVA rate in the bridge group, with none in the no-bridge group. No other arterial thromboembolic events, pump thrombosis or DVT/PE were observed in either group. Conclusion In LVAD patients undergoing thoracentesis, a non-bridging strategy does not appear to elevate the risk of thrombosis compared to a bridging approach. Moreover, the incidence of bleeding, while not statistically significant, trended higher in the bridging group.

Treatment of concomitant persistent chylothorax and superior vena cava syndrome through innominate vein-right atrial bypass.

Persistent chylothorax is a major challenge in paediatric patients. We present a case of a 6.5-kg, one-year-old boy with SVCS and persistent chylothorax, who underwent successful surgery without cardiopulmonary bypass. His medical history included multiple co-morbidities such as myeloproliferative disease, short bowel syndrome, and central vein catheterizations. The patient also had IV thrombosis, progressing to SVC, and was on anticoagulants. Despite dietary changes and somatostatin, his high-output chylous pleural effusion persisted. He was treated with innominate vein-to-right atrial bypass using a 6 mm Dacron graft. Postoperatively, there was a significant reduction in effusion and accelerated recovery. Somatostatin failure was likely due to mechanical obstruction of the thoracic duct.

A real-world pharmacovigilance study of FDA Adverse Event Reporting System (FAERS) for gemcitabine

ABSTRACT Background Gemcitabine is widely used in the treatment of various cancers. This study aims to evaluate gemcitabine-associated adverse events (AEs) using the Food and Drug Administration Adverse Event Reporting System (FAERS) database. Research design and methods We analyzed data spanning from January 2004 to June 2023. Employing reporting odds ratio (ROR) and Bayesian confidence propagation neural network (BCPNN) algorithms, we identified AEs with positive signals in patients administered gemcitabine. Results Out of 16,623,939 reports, 23,645 involved gemcitabine as the ‘primary suspected (PS)’ resulting in 74,306 AEs. Consistent with the reports in the specification and clinical trials, thrombocytopenia, pyrexia, neutropenia, and anemia were the most common AEs. Notably, our study identified some unexpected AEs such as abdominal pain, pleural effusion, ascites, and gastrointestinal hemorrhage, among others. The most significant SOC was ‘Blood and lymphatic system disorders’. The median onset time for gemcitabine-related AEs was 24 days (interquartile range [IQR] 6–82 days), with most cases occurring within the initial 30 days following gemcitabine administration. Conclusion Gemcitabine is associated with a broad spectrum of AEs affecting multiple organ systems, with a notable incidence of hospitalization. The study highlights both expected and unexpected AEs, which could enhance future clinical applications and safety of gemcitabine.

Diagnostic value of ultrasound for community-acquired pneumonia in children and its correlation with serum PCT level and PCIS.

This study aimed to evaluate the diagnostic value of ultrasound for community-acquired pneumonia (CAP) in children. Clinical information of children diagnosed with CAP and a control group of healthy children was collected, and lung ultrasound detection was performed. The lung ultrasound score (LUS) was assessed, and venous blood samples were collected. Serum indexes, including white blood cell count, were analyzed using an automatic immunoassay analyzer, while serum procalcitonin (PCT) level was measured using an enzyme-linked immunosorbent assay. The pediatric critical illness score (PCIS) was also performed for all subjects. White blood cell count, absolute neutrophil count, and respiratory index were significantly higher in the CAP group than those in the control group, while the oxygenation index was markedly lower. Ultrasound detection results showed that the CAP group exhibited significantly higher detection rates of pleural effusion, interstitial lung changes, lung consolidation, B-lines, air bronchogram signs, and reduced or absent lung sliding signs compared with the control group. In addition, the LUS and PCT levels were markedly higher in the CAP group, while the PCIS was notably lower. Further analysis exhibited that the LUS in the CAP group was significantly positively correlated with PCT levels and negatively correlated with PCIS. The receiver operating characteristic curve indicated that the area under the curve of LUS for diagnosing children with lung infection was 0.841. LUS is closely related to serum PCT level and PCIS. Lung ultrasound detection demonstrates high sensitivity and specificity, indicating its valuable clinical diagnostic utility for CAP in children.

Tuberculous Pleurisy in a Patient with a History of Breast Cancer: Diagnostic Challenges and Management Options

Background: Tuberculosis (TB) and cancer are increasingly prevalent diseases that can be challenging to diagnose due to similarities in clinical and radiological findings. This case report describes a 46-year-old woman with a history of breast cancer who developed tuberculous pleurisy (TP). Case presentation: A 46-year-old woman who underwent mastectomy and chemotherapy for BC in 2023 had hypertension, but no history of TB. The patient presented with dry cough, fever, and stomach discomfort, with an oxygen saturation level of 60%, but no respiratory distress before their appointment. Microscopy and culture tests were negative for Mycobacterium TB, A positive result was observed with an IFN-γ level of 0.35 IU/ml and 26% of the negative control after TB antigen stimulation. Histological analysis using hematoxylin and eosin staining showed Langhans giant cells, epithelioid cell granulomas, caseous necrosis, and necrotic foci. These findings indicate granulomatous inflammation with no signs of malignancy. Following the diagnosis, the patient received a daily dose of 300 mg isoniazid, 600 mg rifampin, 1500 mg pyrazinamide, and 10 mg pyridoxine for six months without any adverse effects. Conclusion: Physicians must employ a combination of diagnostic techniques, including morphological and microbiological confirmation, to accurately diagnose pleural effusion in this patient population.

Recurrent pulmonary thromboembolism with cardiac tamponade as initial manifestations of lupus and antiphospholipid syndrome: a case report

Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease with an important course due to systemic compromise. SLE is frequently associated with antiphospholipid syndrome, and pulmonary thromboembolism (PE) is particularly common. It is extremely rare for PE to be the initial clinical presentation and even more uncommon for it to coincide with cardiac tamponade, representing a challenge in diagnosis and management. We present a case of a 42-year-old woman with recurrent PE with severe pleural and pericardial effusion, hemodynamic instability, and cardiac tamponade. Laboratory workup revealed hypocomplementemia, leukopenia, negative SLE antibodies, and a positive lupus anticoagulant. This case emphasizes the importance of determining the etiology of PE, assessing risk classification, and implementing proper management, which are crucial for the patient's survival and outcome.

A Unique Case of Hypervirulent Klebsiella Pneumoniae Invasive Syndrome with Endogenous Endophthalmitis and Left Renal Vein Thrombosis without Liver Abscess.

This case report presents a rare instance of hypervirulent Klebsiella pneumoniae invasive syndrome (KPIS) without hepatic involvement. It highlights an atypical presentation as this syndrome is characterized by liver abscesses. A 54-year-old female of South Asian descent presented to the emergency department with abdominal pain, fever, chills, nausea, and vomiting. Lab investigations showed hyperglycaemia, leukocytosis, and elevated procalcitonin. Imaging revealed bilateral acute pyelonephritis with early abscess formation in the left kidney, bilateral pleural effusions, diffuse multi-lobar consolidations, minimal ascites, and left renal vein thrombosis. The patient was treated as a case of septic shock secondary to hypervirulent K. pneumoniae with complications evolving into acute pyelonephritis and endogenous endophthalmitis. K. pneumoniae, known for its polysaccharide capsule, can lead to severe complications in immunocompromised patients, such as endogenous endophthalmitis, liver abscess, and pyelonephritis. Endophthalmitis, a critical ocular emergency, can result in permanent vision loss. The patient's ocular outcomes remain uncertain due to a lack of follow-up, but prompt interdisciplinary intervention led to the resolution of other comorbidities. This case highlights the importance of considering hypervirulent K. pneumoniae as a cause of severe infection without liver abscess. It also underscores the importance of immediate multidisciplinary management to address the systemic complications associated with this infection and the importance of connecting different symptoms to one aetiology. Klebsiella pneumoniae invasive syndrome (KPIS) should be considered in patients with positive Klebsiella pneumoniae infection affecting more than one organ system.KPIS may present atypically, such as in the absence of liver abscesses and with the presence of thrombosis.Hypervirulent and hypermucoviscous strains of Klebsiella pneumoniae should be considered in cases of KPIS.

Ruptured solitary fibrous tumor of the pleura with hemothorax: a case report

BackgroundThe majority of the patients with a solitary fibrous tumor (SFT) of the pleura are asymptomatic, and rupture of an SFT with hemothorax is rare.Case presentationA 48-year-old man was taken by ambulance to our hospital because of sudden onset of left chest pain. Two months before the referral, a tumor was detected in the left upper lobe of the lung by screening computed tomography at another hospital, and further observation was recommended, because the tumor was suspected to be benign. Our contrast-enhanced computed tomography analysis of the chest revealed a solid tumor (5 cm in diameter) with an irregular enhancement effect close to the pericardium and pleural effusion in the left thoracic cavity. Pleural effusion was not detected in the previous imaging analysis. CT number of the pleural effusion was 40 HU, and the pleural effusion was suspected to be hematogenous. Therefore, rupture of the tumor with bleeding was suspected as the cause of the effusion because of the sudden onset. Preoperative diagnosis was a mediastinal tumor, such as a teratoma, because the tumor was close to the pericardium. Thoracoscopic surgery was performed with the patient in the right lateral decubitus position; bloody pleural effusion was observed and drained. The tumor originated from the visceral pleura of the left upper lobe of the lung and was resected with a surgical stapler. Macroscopic analyses of the resected tumor indicated that bleeding were caused by the rupture of the tumor at the defect of the capsule wall. The operation took 63 min. The postoperative pathological diagnosis was a benign SFT. Hemorrhage was observed just under the capsule wall of the tumor. The postoperative course of the patient was uneventful, and he was discharged 2 days after surgery.ConclusionsEven when an SFT is neither huge nor malignant, rupture can occur, and resection should be considered regardless of the size or malignant characteristics. After an SFT rupture, careful follow-up is needed to monitor for the intrathoracic recurrence or dissemination of the tumor.

Minimally Invasive Transhiatal Esophagectomy Using Antegrade Inversion Technique in Esophageal Cancer: 10-Year Experience from a Tertiary Care Center.

Background: Esophageal cancer surgery aims for curative intent but carries high complication rates. Transthoracic esophagectomy is the dominant approach, however, transhiatal esophagectomy (THE) offers selective advantages in certain clinical scenarios. Minimally invasive THE (MI-THE) is an evolving technique with limited data. Methods: This retrospective study reviewed 38 patients with esophageal cancer who underwent MI-THE using "Antegrade Inversion Technique" between 2013 and 2023 at a tertiary care center. Perioperative outcomes were analyzed. Data were presented as mean with standard deviation, median with interquartile range, and percentages. Results: Most patients (86.8%) had early-stage cancer. Median operative time was 375 minutes, hospital stay was 8 days, and intensive care unit stay was 3 days. All patients achieved a negative resection margin. Pleural effusion (57.9%) was the most common complication, followed by pneumothorax (31.6%) and surgical site infection (15.8%). Anastomotic leak rate was 13.2%. There was no mortality. Conclusions: MI-THE appears safe and feasible with encouraging perioperative outcomes, particularly for early-stage disease and high-risk patients. While potentially offering advantages over open THE, further research is needed to definitively establish its role compared to traditional approaches.

Study on the Consistency of Point-of-Care Ultrasound and Chest X-ray in the Diagnosis of Postoperative Thoracic Abnormalities in Children with Congenital Heart Disease

Objective: This study aimed to explore the consistency of point-of-care ultrasound (POCUS) and chest X-ray in the diagnosis of postoperative thoracic abnormalities in children with congenital heart disease. Methods: The clinical data of 68 children with congenital cardiosurgery in our hospital from January 2021 to August 2024 were retrospective analyzed. Six children were excluded, and 62 cases were finally included. POCUS was performed 24 hours after surgery. After the examination of POCUS, chest X-ray examination was conducted. The results of POCUS and chest X-ray examinations in children, as well as the clinical incidence of postoperative thoracic abnormalities were recorded. The effect of POCUS and chest X-ray in the diagnosis of postoperative thoracic abnormalities was compared. Results: POCUS had slightly higher diagnostic sensitivity of pleural effusion and atelectasis than chest X-ray. The sensitivity of POCUS in diagnosing pulmonary edema was consistent with that of chest X-ray. However, POCUS had slightly lower sensitivity in diagnosing pneumothorax than chest X-ray. The specificity of POCUS in diagnosing pneumothorax and atelectasis was consistent with that of chest X-ray. However, POCUS had slightly higher specificity in the diagnosis of pleural effusion and pulmonary edema than chest X-ray. The kappa values of POCUS and chest X-ray in diagnosing pleural effusion, pneumothorax, atelectasis and pulmonary edema were 0.546, 0.565, 0.502 and 0.701, respectively. Conclusion: POCUS and chest X-ray examinations have good consistency in the diagnosis of postoperative thoracic abnormalities in children with congenital heart disease.

Lobar graft evaluation in cadaveric lobar lung redo transplantation after living-donor lobar lung transplantation: a case report

BackgroundLung transplantation is a vital option for patients with end-stage lung disease. However, it faces a significant challenge due to the shortage of compatible donors, which particularly affects individuals with small chest cavities and pediatric patients. The novel approach of cadaveric lobar lung transplantation is a promising solution to alleviate the donor shortage crisis. Both the mid-term and long-term outcomes of lobar lung transplantation are comparable to those of standard lung transplantation. However, patients undergoing lobar lung transplantation reported a significantly higher rate of primary graft dysfunction compared to patients undergoing standard lung transplantation. Therefore, careful donor selection is critical to improve outcomes after lobar transplantation. However, no established method exists to evaluate each lung lobar graft of deceased donors. This case report describes a case of cadaveric lobar lung transplantation to overcome size mismatch and donor shortage, with particular emphasis on lobar graft evaluation.Case presentationA 39-year-old woman with scleroderma-related respiratory failure was listed for deceased donor lung transplantation due to a rapidly progressing disease. Faced with a long waiting list and impending mortality, she underwent bilateral living-donor lobar lung transplantation donated by her relatives. Post-transplant complications included progressive pulmonary vein obstruction and pleural effusion, which ultimately required retransplantation. An oversized donor with pneumonia in the bilateral lower lobes was allocated. Lung ultrasound was used to evaluate each lung lobar graft during procurement. The right upper and middle lobes and left upper lobe were confirmed to be transplantable, and lobar lung redo transplantation was performed. The patient’s post-transplant course was uneventful, and she was discharged home and returned to her daily activities.ConclusionsThis case highlights the clinical impact of cadaveric lobar lung transplantation as a feasible and effective strategy to overcome the shortage of donor lungs, especially in patients with small thoracic cavities. By establishing donor lung evaluation techniques and overcoming anatomical and logistical challenges, cadaveric lobar lung transplantation can significantly expand the donor pool and offer hope to those previously considered ineligible for transplantation.

Safety and risk analysis of total resection surgery for thoracic and lumbar spinal tumors: a decadal analysis of 103 cases

Study designRetrospective cohort study.PurposeTo explore the complications and risk factors for total resection (TR) of primary thoracic and lumbar spinal tumors over the past decade at our institution.MethodsPatients meeting inclusion criteria (primary spinal tumors, thoracic or lumbar location, TR at our center) were included. Demographic characteristics, surgical data, perioperative complications and management results were reviewed. Patients were stratified by tumor site, the number of excised segments, and recurrence status to elucidate distinctive characteristics.ResultsThe cohort comprised 103 patients, with a mean age of 35.8 years. On average, 1.83 vertebral segments were resected per patient. Perioperative complications were substantial, totaling 166 events, with 71 classified as major and 95 as minor, yielding an average of 1.61 complications per patient. No perioperative deaths occurred, but 79 patients (76.7%) experienced at least one complication. Multiple vertebral sections correlated with a higher complication rate (P = 0.031), and lumbar surgeries exhibited elevated risks of large vascular injury (P = 0.001), neurological deterioration, and cerebrospinal fluid leakage compared to thoracic cases. Conversely, thoracic spinal procedures showed a higher rate of pleural effusion (P = 0.004). Binary logistics stepwise regression identified multi-segmental resection as the independent risk factor for major perioperative complications.ConclusionsTR of primary spinal tumors is associated with a high perioperative complication rate, although most events have a favorable prognosis. Complication characteristics vary based on the surgical site, number of excised segments, and surgical history. A nuanced preoperative evaluating approach considering patient age, surgical segments, and extent of resection is crucial.

Unveiling the Rarity: Pleural Metastasis of Papillary Thyroid Cancer – A Case Report and Clinical Implications

Papillary thyroid cancer (PTC) is an epithelial malignancy arising from the follicular cells within the thyroid, typically slow-growing with a benign course (5-year survival >99% in locally contained malignancies). However, in unusual cases, this condition can spread to the pleura, leading to a malignant pleural effusion. The authors present a case of an 80-year-old female presenting with dyspnoea following treatment for suspected bacterial pneumonia. Imaging revealed a substantial left-sided pleural effusion. Despite interventions such as thoracentesis and intravenous antibiotics, the pleural effusion persisted. Subsequent video-assisted thoracic surgery revealed pleural biopsies positive for PTC, a disease previously believed to have been cured almost 6 decades ago. Pleural involvement in patients with PTC is exceptionally rare. A literature review conducted between 1992–2023 revealed merely seven published reports documenting PTC metastasis to the pleura. The authors’ case emphasises the significance of exploring various potential causes of a patient showing signs of subacute dyspnoea, particularly in individuals previously diagnosed with PTC, as it emphasises the possibilities of unforeseen recurrence, featuring the uncertainties and complexities of managing PTC.
