Real-world evidence in extensive disease small cell lung cancer: The missing piece of the puzzle.

Small cell lung cancer (SCLC) is a highly aggressive disease, often diagnosed at an advanced stage and with limited treatment options. In recent years, immunotherapy has been approved in combination with chemotherapy in the first line setting of extensive stage disease (ES-SCLC). However, only 10-15 % of patients with ES-SCLC treated with chemoimmunotherapy (CT-IO) experience a long-term benefit. In addition, patients are often clinically frail due to advanced age, comorbidities, and disease-related symptoms, making SCLC a challenging condition. Real-world evidence (RWE) becomes particularly valuable in this scenario, not only to confirm the results of pivotal trials, but also to evaluate the outcomes of CT-IO in populations that are generally excluded from clinical trials. RWE could also define the role of integrative treatments such as thoracic consolidation radiotherapy and prophylactic cranial irradiation, which are used in selected patients in the clinical practice but were scarcely applied in pivotal trials. In this review, we focused on RWE in ES-SCLC, with the aim of improving clinical decision making. Notably, real-world data have largely confirmed the efficacy and safety of CT-IO observed in pivotal clinical trials, with a possible benefit even in more fragile patients. However, these studies also highlight that a significant proportion of the ES-SCLC population remains untreated due to poor clinical conditions.

Retroperitoneal Soft Tissue Sarcoma and Kidney Autotransplantation: A Case Report

ABSTRACTSoft tissue sarcomas (STSs) are rare malignancies, with retroperitoneal soft tissue sarcoma (RPS) constituting 10%–15% of all STSs. RPS often presents late due to minimal early symptoms, typically requiring complete en‐bloc resection for optimal survival outcomes. Achieving radical resection can be challenging due to the tumor's proximity to vital organs. In cases where the kidney is involved, a nephrectomy can lead to significant morbidity, especially in patients with pre‐existing renal impairment. Kidney autotransplantation offers a unique solution by preserving renal function in these cases, avoiding the need for dialysis and immunosuppressive therapy. This case report presents a 61‐year‐old female with a large RPS encasing her only functioning kidney. After unsuccessful neoadjuvant chemotherapy, she underwent an en‐bloc resection and subsequent autotransplantation. Postoperatively, she experienced complications such as pneumonia and bowel obstruction due to poor clinical status, but after recovery, she has remained disease‐free at 1‐year follow‐up. This case illustrates the potential of kidney autotransplantation in selected cases to prevent treatment‐induced renal failure. Although the risk of recurrence is relevant, autotransplantation provides an option for preserving renal function while allowing for curative resection, with careful consideration of the balance between recurrence risk and morbidity.

Pushing the Boundaries of Ampullectomy for Benign Ampullary Tumors: 25-Year Outcomes of Surgical Ampullary Resection Associated with Duodenectomy or Biliary Resection.

Background: Surgical resection for ampullary lesions lacks clear guidelines. Pancreaticoduodenectomy (PD) is the standard treatment for malignant ampullary tumors but is often excessive for ampullary adenomas (AAs) due to its high morbidity and mortality. Transduodenal ampullectomy (TDA) is generally reserved for small benign lesions where endoscopic treatment fails, but its role in early ampullary cancers is debatable. This study presents our 25-year outcomes with TDA for benign ampullary tumors. Methods: We conducted a retrospective cohort study with prospectively collected data from patients with benign ampullary lesions who underwent TDA between January 1996 and November 2023. Primary outcomes were the 30-day overall and severe (Clavien-Dindo ≥ IIIa) morbidity rates and the 90-day mortality rate. Categoric variables were presented as absolute and relative frequencies, and quantitative variables were presented as means (standard deviation, SD) or medians (range or interquartile range, IQR). Results: Fifty-three patients (29 male; mean [SD] age 62.5 [14.6] years) underwent TDA. The 30-day morbidity rate was 32.1% (17/53 patients), with five (9.4%) cases being severe. The 90-day mortality rate was 1.9%. Definitive histopathology identified 38 (71.7%) AAs and five (9.4%) infiltrating ampullary adenocarcinomas, two (40.0%) of which required subsequent PD. Six (11.3%) patients experienced recurrence. Overall, nine (16.9%) patients died. Conclusions: TDA is a safe and effective technique with acceptable morbidity for non-infiltrating lesions, especially in patients with poor clinical status. Choosing between TDA and PD depends on tumor size, dysplasia grade, and institutional expertise. Lifelong endoscopic surveillance post-TDA is essential for timely recurrence detection.

Analysis of the health conditions of migrants and asylum seekers in reception centers: From scene investigation to the evaluation of signs of torture

The phenomenon of migration is an international issue that mainly concerns Europe. In Italy, because of its close proximity to Africa, there are many migrant landings, especially on the islands of Lampedusa and Sicily. Migrants and asylum seekers suffer torture on their journey to their destination country, however, most of the time the signs are not always recognizable. In the present study, a scene investigation was carried out in a reception center for level II immigrants in Sicily, in order to evaluate the hygiene conditions of the migrants and asylum seekers inside this center. Subsequently 26 migrants and asylum seekers, all minors and males, were examined in a clinic of the Department of Forensic Medicine of the University of Catania, with the help of a native speaker interpreter and applying the Istanbul Protocol. The scene investigation demonstrated the poor clinical conditions of the reception center and the failure to comply with emergency regulations. The physical examination of the migrants and asylum seekers demonstrated that all the torture reported had taken place in Libya. However, only 4 migrants and asylum seekers showed signs of violence consistent with torture, compatible with the Istanbul Protocol. Nine migrants and asylum seekers (34.6 %) reported having pathologies and asked to undergo a medical examination in a hospital but were not listened to by the reception center staff. Two migrants and asylum seekers reported having worn the same clothes for several weeks to the reception center staff. In particular, all the migrants and asylum seekers reported having suffered torture using blunt instruments, especially beatings with truncheons. One migrant and asylum seeker reported being detained for days without food, instead 1 migrants and asylum seekers reported being kidnapped-blindfolded-stripped naked for days, and 1 migrants and asylum seekers reported having contracted infections, including scabies, with electrical and thermal trauma. Despite the international commitment to the phenomenon of migration, migrants and asylum seekers continue to receive abuse and torture. Furthermore, most migrants and asylum seekers studies primarily involve surveys, and few have applied the Istanbul Protocol to a sizable sample. An original aim of the study is the use of forensic tools to assess the sanitary and hygienic conditions of a migrant reception center, with the secondary aim of assessing alleged cases of torture.

Serum transferrin concentration: a new prognostic biomarker in heart failure with reduced ejection fraction

Abstract Introduction Iron deficiency (ID) is a common comorbidity in patients with reduced heart failure (HFrEF), and is associated with poor clinical status and outcomes, but there is not enough data investigating serum transferrin concentration (STC) as a biomarker HFrEF to predict prognosis and mortality. Purpose We investigated relationship between STC at admission and all-cause mortality during follow-up in HFrEF. Methods We reviewed the medical data of 420 patients hospitalised in our institution for HFrEF over a period of 18 months. Laboratory tests were performed on the first 24 hours of admission. Patients were divided into two groups according to STC, using the value of 199 μg/dl as the cut-off. This value was determined from the ROC analysis to be the value with the highest sensitivity and specificity. Then we analysed relationship between STC at admission and all-cause mortality during follow-up between the two groups, after adjustment of the various variables described in the literature. Results Of 420 patients with HFrEF, 18.6% had STC ≤ 199 μg/dl (group 1) and 81.4% had STC > 199 μg/dl (group 2) with no difference in age and sex distribution (p = 0.873 ; p = 0.304). Patients with low STC were more likely to be diabetic (70.5% vs 46.5% ; p < 0.001), have dyslipidemia (52.6% vs 33%; p = 0.002), and history of chronic renal failure (6.4% vs 2.0% ; p = 0.045). There was no relation between STC and NYHA class (p = 0.776), hospital stay (p = 0.491) nor EF (p = 0.146). Biologically, lower STC was significantly associated with higher serum ferritin (292.77 vs 198.17 ; p < 0.001), TSAT (68.30 vs 22.21 ; p = 0.020) and C-reactive protein (CRP) (124.91 vs 39.98 ; p = < 0.001), lower plasma B-type natriuretic peptide (BNP) (5798.32 vs 6449.97 ; p = 0.002), with no difference in haemoglobin level (p = 0.272) and estimated glomerular filtration rate (eGFR) (p = 0.260). The prevalence of iron deficiency by the ESC criteria was lower in those with low STC; ferritin < 100 μg/l (15.4% vs 29.2% ; p = 0.015) or TSAT < 20% (33.3% vs 51,8% ; p = 0.004). There was no difference between the two groups in term of NYHA class and EF at three months (p = 0.87, p = 0.108). However, all-cause mortality during follow-up was significantly associated with low STC (37.2% vs 17.0% ; p <0.001). (Figure 1) In multivariable analysis, all-cause mortality was independently associated with STC ≤ 199 μg/dl (HR 1.71; 95% CI : 1.08 ; 2.7 ; p = 0.02). This is the same finding for the ischaemic origin of HFrEF (HR 2.1 ; p = 0.001), therapeutic inertia during follow-up (HR 5.53 ; p <0.001) and EF < 36% (HR 1.03 ; p = 0.047) (Figure 2). Conclusion More data are required before the routine use of STC as a biomarker of prognosis in HFrEF, but it may represent a reliable and cost-effective option to predict mortality.FIGURE 1FIGURE 2

Win ratio analysis of transvenous phrenic nerve stimulation to treat central sleep apnoea in heart failure.

Central sleep apnoea (CSA) is present in 20-40% of heart failure (HF) patients and is associated with poor clinical outcomes and health status. Transvenous phrenic nerve stimulation (TPNS) is an available treatment for CSA in HF patients. The impact on HF outcomes is incompletely understood. The win ratio (WR) allows inclusion of multiple endpoint components, considers the relative severity of each component, and permits assessment of recurrent events in evaluation of clinical benefit. A WR hierarchy was pre-defined for analysis of the HF subgroup of the remedē® System Pivotal Trial. The analysis used three hierarchical components to compare all treated to all control subjects: longest survival, lowest HF hospitalization rate, and ≥2-category difference in Patient Global Assessment at 6months. Sensitivity analyses were performed substituting Epworth Sleepiness Scale and 4% oxygen desaturation index for the third component, and a 4-component WR hierarchy was also evaluated. Ninety-one HF subjects, 43 receiving TPNS and 48 in the control group, provided 2064 pairwise comparisons. More patients treated with TPNS experienced clinical benefit compared with control (WR 4.92, 95% confidence interval 2.27-10.63, P<0.0001). There were 1111 (53.83%) winning pairwise comparisons for the treatment group and 226 (10.95%) for the control group. Similarly, large WRs were observed for all additional WR hierarchies. This WR analysis of the remedē® System Pivotal Trial suggests that TPNS may be superior to untreated CSA in HF patients with CSA using a hierarchical clinical benefit endpoint composed of mortality, HF hospitalization, and health status.

Fecaloma: Classification, Treatment, and Outcomes

Abstract Background: Fecaloma is a mass of hardened and impacted feces. Its prevalence is high in elderly individuals and patients with neuromuscular changes in the gastrointestinal tract. Objectives: The purpose of this study was to analyze the causes, treatment, and outcomes of fecal impaction in a large group of patients. Design: This study was a cross-sectional, observational, retrospective study. Setting: Núcleo de Estudo de Doença de Chagas (Refering Center for Chagas disease), Hospital das Clínicas, Universidade Federal de Goiás, Goiania, Brazil. Patients and Methods: The records of patients referred to perform serology for Chagas disease with a history of fecal impaction were analyzed. Demographic data, causes, extension of fecal mass, complication (volvulus and bowel perforation), type of treatment, and outcomes were obtained. Main Outcomes and Measurements: Differences between two groups of patients with fecaloma: chagasic megacolon and normal population. Sample Size: A total of 1054 patients were included. Results: The median age of the patients was 64 years, with higher prevalence in women at 56.8%, and serology for Chagas disease was positive in 80.3%. Constipation was reported in 80.3% and the use of laxatives in 59.7%. The most prevalent location of fecaloma was in the rectosigmoid (64%), and the most associated complication was volvulus (11%). Most patients were managed with conservative treatment (71.1%), and surgical intervention (28.9%) was needed in complicated patients. Conclusion: Most patients with fecaloma were elderly women and the main cause was Chagas disease. Constipation and the rate of laxative use were significant in this population. Conservative approach resolves most cases. Surgery may be indicated in refractory cases and in cases of volvulus or bowel perforation. Limitations: This is a retrospective study, and many patients do not have an adequate follow-up file. Colonic evaluation is limited by poor clinical condition and age. Barium enema exam may overestimate colorectal dilation due to its methodology. Conflict of Interest: The authors have no conflict of interest to declare.

Respiratory and physical therapy in the intensive care unit after liver transplantation for acute-on-chronic liver failure: a case report.

Acute-on-chronic liver failure (ACLF) is a severe clinical condition for which liver transplantation (LT) is the only curative option. Due to the recipients' generally poor pre-operative clinical conditions and extensive surgery, post-LT respiratory disorders are very common and significantly contribute to related morbidity and mortality. We report the case of a 49-year-old patient with ACLF grade 3 who has been taken care of by the Respiratory Physiotherapy Team since hospital admission. After the extubation, the patient was supported with non-invasive ventilation and mechanical in-exsufflation; meanwhile, early resistance and functional training were started. No adverse events occurred during physiotherapy sessions, and the patient returned home without respiratory support. Respiratory and physical therapy in the intensive care unit after LT were safe and feasible interventions for this patient. Given the high incidence of postoperative pulmonary complications and the high rehabilitation needs, we suggest that physiotherapy should be provided for ACLF recipients.

Clinical characteristics and short-term outcomes in patients with cardiogenic shock undergoing mechanical circulatory support escalation from intra-aortic balloon pump to impella: From the J-PVAD registry.

An escalation strategy from intra-aortic balloon pump (IABP) to Impella (AbioMed, Danvers, MA, USA) is proposed in patients with cardiogenic shock (CS) refractory to IABP therapy, but its clinical data are lacking. This study aimed to elucidate the clinical characteristics and short-term outcomes in patients undergoing IABP-Impella escalation. From the Japanese nationwide registry of Impella (J-PVAD), a total of 2578 patients with CS receiving Impella support were classified into the IABP-Impella group (n = 189) or the Primary Impella group (n = 2389). We applied 1:3 propensity score (PS) matching, selecting 185 patients and 555 patients, respectively. Before matching, the IABP-Impella group presented longer shock-to-Impella time, worse laboratory data, and more frequent inotropes and pulmonary artery catheter use than the Primary Impella group. After matching, the baseline characteristics were well-balanced. Regarding the 30-day clinical outcomes in the PS-matched cohort, there were no significant differences in the rates of mortality and major complications (a composite of bleeding, hemolysis, infection, stroke, myocardial infarction, limb ischemia, and vascular injury) between the groups. However, The IABP-Impella group showed a significantly higher rate of infection (10.3 % vs. 5.6 %, p = 0.042) and additional mechanical circulatory support use (34.1 % vs. 23.8 %, p = 0.008) than the Primary Impella group. Compared to patients with primary Impella support, those undergoing IABP-Impella escalation showed similar 30-day mortality and major complications despite poorer clinical conditions before Impella support and a more complicated clinical course after Impella insertion.

Prevalence of ruptured small and very small aneurysms: a retrospective single-centre study.

To retrospectively assess the occurrence and consequences of subarachnoid haemorrhages (SAH) caused by ruptured intracranial aneurysms (RIA), particularly focusing on the treatment outcomes of small aneurysms treated with either endovascular embolisation or surgical intervention. We retrospectively analysed data from 408 patients (144 males and 264 females) who were hospitalised between 2013 and 2022 at the Department of Neurosurgery and Neurology in University Hospital Nr 2 in Bydgoszcz, Poland. Clinical conditions at admission, assessed using the Glasgow Coma Scale, Hunt-Hess scale (H-H), modified Rankin scale (mRS), as well as age and sex, were recorded. Additionally, aneurysm data including size, localisation, and the method and outcome of endovascular or surgical treatment were examined. Among the 408 patients hospitalised due to SAH, the most common localisation of the 375 RIAs was the anterior communicating artery (AcomA) complex (111 cases, 29.6%), followed by the medial cerebral artery (MCA) (95 cases, 25.3%), internal carotid artery (ICA) (94 cases, 25%), and the vertebrobasilar complex (consisting of the basilar artery (BA) - 25 cases, vertebral artery (VA) - 13 cases, anterior inferior cerebellar artery (AICA) - one case, and posterior inferior cerebellar artery (PICA) - four cases), which accounted for 43 SAH cases (11.46%). In 33 cases, neither RIA nor a haemorrhage source was identified, or arteriography showed no cerebral arteries contrast flow. Among the examined group of 375 RIAs, 45 (12%) were microaneurysms (≤ 3 mm), 35 (9%) were small aneurysms (3 ≤ 5 mm), 89 (24%) were medium-sized (5 ≤ 7 mm), and 151 (40%) were large aneurysms (> 7 mm), serving as the source of SAH. A better outcome was significantly associated with lower initial H-H grade (p < 0.001), higher GCS (p < 0.001), lower mRS at admission (p < 0.001), younger age (p < 0.001), smaller size (≤ 3 mm) (p < 0.001), and endovascular treatment (p < 0.001). In this series, over 21% of patients suffered from SAH resulting from ruptured small aneurysms (≤ 5 mm), with 12% specifically attributed to ruptured very small aneurysms (≤ 3 mm), despite large aneurysms (> 7 mm) being the most prevalent source of bleeding in 40% of cases. A worse prognosis was primarily associated with the severity of SAH, reflected in poorer clinical status at admission and older age. Endovascular embolisation was found to be effective and associated with better outcomes compared to surgical treatment.

Circadian lighting effect for inpatients with schizophrenia: A prospective cohort study.

In schizophrenia, nonspecific lighting likely causes sleep timing disturbances, leading to distress and poorer clinical status. However, the effect of exposure to circadian lighting on psychopathology outcome in schizophrenia remains unknown. Hence, this study aimed to develop such an intervention and investigate its impact on schizophrenia. Twenty schizophrenia patients at a psychiatric nursing institute were monitored over 10weeks, with assessments using the Brief Psychiatric Rating Scale (BPRS) and Mini-Mental State Examination (MMSE) conducted at baseline, weeks 3 (T1), 7 (T2), and 10 (T3). Circadian lighting significantly improved BPRS scores between T1-T2 (p<.05) and T1-T3 (p<.001), with affectivity scores also showing significant enhancements postintervention. Notably, female participants exhibited substantial improvements in BPRS scores from T1 to T3 (p<.01), while male participants demonstrated significant gains in MMSE scores from T1 to T2 (p<.01). Circadian lighting presents a promising intervention for improving psychiatric outcomes in schizophrenia, with distinct benefits observed across different psychopathological aspects and genders. These findings underscore the potential of lighting chronotherapy in psychiatric clinical practice and warrant further exploration in related research.

Diaphragmatic Herniation with Pneumothorax Due to Barotrauma – Lessons to Learn: A Case Report

Diaphragmatic hernia is usually congenital or follows thoracoabdominal injury. Diaphragmatic hernia combined with pneumothorax is a rare combination in the clinical setting, where pneumothorax is usually secondary to hollow viscera perforation in the long-term complications of diaphragmatic herniation or rupture of ectopic endometrium over the diaphragm during menstruation. Unlike the aforementioned conditions, we describe a 67-year-old man with chronic diaphragmatic hernia who suffered from pneumothorax and pneumoperitoneum secondary to pulmonary bulla by barotrauma during mechanical ventilation. Computed tomography showed scattered free gas in the thoracic and abdominal cavities, while there was no tenderness and rebound tenderness. The patient was managed conservatively with low PEEP and a lung-protective mechanical ventilation strategy. Finally, the oxygenation index gradually rose from 58 to 107. Unfortunately, in light of the patient’s poor clinical status and significant comorbidities, the patient passed away peacefully 3 weeks after hospital admission. Diaphragmatic hernia combined with pneumothorax should be differentiated from tension pneumothorax. Whether to intubate chest drainage depends on the cause of pneumothorax and pneumoperitoneum, as well as the risks and benefits of chest drainage. Additionally, mechanical ventilation should be applied cautiously, and respiratory parameters should be adjusted reasonably in patients at high risk of pneumothorax.

Resilience After High-Grade Subarachnoid Hemorrhage: A Prospective Cohort Study on Quality of Life.

Treatment of patients who present with poor clinical condition is often postponed until neurological improvement is observed. Despite previous studies, it is still unclear how survivors perceive their quality of life (QoL). This study aimed to evaluate self-perceived QoL in patients with aneurysmal subarachnoid hemorrhage who present with poor clinical condition, as defined by World Federation of Neurosurgical Societies (WFNS) grades 4 to 5, compared with those who present in more favorable clinical condition (WFNS 1-3). Between 2011 and 2021, 1160 patients with aneurysmal subarachnoid hemorrhage were admitted to the Amsterdam UMC. Among the 845 patients who survived, 537 participated in the QoL questionnaires. Patient characteristics, complications, EQ-5D questionnaires, modified Rankin Scale, and Hospital Anxiety and Depression Scale were analyzed using the nonparametric Mann-Whitney U test for continuous variables or the Pearson χ 2 test for categorical variables. Of the 537 responders, 452 (84%) presented with low grade (WFNS 1-3) and 85 (16%) presented with high grade (WFNS 4-5). The high-grade group reported a self-perceived QoL score of 70 (of 100), while the low-grade group reported a score of 75 ( P = .12). The mean EQ-5D index value was 0.74 for the high-grade group and 0.81 for the low-grade group ( P < .01). In the high-grade group, 61 patients (72%) had a favorable outcome (modified Rankin Scale 0-3) compared with 419 (94%) in the low-grade group ( P < .001). High-grade WFNS patients rated their QoL as satisfactory, with only a marginal 5-point difference on a 100-point scale compared with low-grade WFNS patients. In addition, almost three-quarters of high-grade WFNS survivors achieved a favorable outcome. Given that a subset of patients, despite presenting with a poor clinical condition, still achieve a favorable outcome, these findings reinforce our perspective advocating for early and comprehensive treatment.

Predictors and surgical outcome of hemorrhagic metastatic brain malignancies

PurposeIntracerebral metastases present a substantial risk of tumor-associated intracerebral hemorrhage (ICH). This study aimed to investigate the risk of hemorrhagic events in brain metastases (BM) from various primary tumor sites and evaluate the safety and outcomes of surgical tumor removal.MethodsA retrospective, single-center review of medical records was conducted for patients who underwent BM removal between January 2016 and December 2017. Patients with hemorrhagic BM were compared to those with non-hemorrhagic BM. Data on preoperative predictors, perioperative management, and postoperative outcomes were collected and analyzed.ResultsA total of 229 patients met the inclusion criteria. Melanoma metastases were significantly associated with preoperative hemorrhage, even after adjusting for confounding factors (p = 0.001). Poor clinical status (p = 0.001), larger tumor volume (p = 0.020), and unfavorable prognosis (p = 0.001) independently predicted spontaneous hemorrhage. Importantly, preoperative use of anticoagulant medications was not linked to increased hemorrhagic risk (p = 0.592). Surgical removal of hemorrhagic BM, following cessation of blood-thinning medication, did not significantly affect intraoperative blood loss, surgical duration, or postoperative rebleeding risk (p > 0.096). However, intra-tumoral hemorrhage was associated with reduced overall survival (p = 0.001).ConclusionThis study emphasizes the safety of anticoagulation in patients with BM and highlights the safety of neurosurgical treatment in patients with hemorrhagic BM when blood-thinning medication is temporarily paused. The presence of intra-tumoral hemorrhage negatively impacts survival, highlighting its prognostic significance in BM patients. Further research with larger cohorts is warranted to validate these findings and elucidate underlying mechanisms.

Clinical outcomes of posterior fossa arteriovenous malformations: a single center experience

BackgroundPosterior fossa arterio-venous malformations (pfAVMs) are challenging lesions due to the anatomical particularities of the posterior fossa, and the high incidence of hemorrhagic presentation. The two most important goals when treating AVMs are preserving neurological function and preventing rupture, or a second hemorrhage. The aim of this study was to analyze the clinical and imaging features of pfAVMs to identify the factors that influence the prognosis of these patients.MethodsWe conducted a single-center retrospective observational study that included patients treated at our institution with pfAVMs between January 1997 and December 2021.ResultsA total of 48 patients were included. A good modified Rankin score (mRS) was observed in 33 cases (69%) at presentation. Thirty-four patients (71%) presented with a ruptured AVM. Out of these, 19 patients (40%) had intraventricular hemorrhage. Microsurgical resection was performed in 33 cases (69%), while in the other cases, the patients opted for conservative management (7 cases, 15%), stereotactic radiosurgery (SRS) (6 cases, 12%), or endovascular treatment (2 cases, 4%). Patients ≤ 30 years old were more prone to hemorrhagic presentation (OR: 5.23; 95% CI: 1.42–17.19; p = 0.024) and this remained an independent risk factor for rupture after multivariate analysis as well (OR: 4.81; 95% CI: 1.07–21.53; p = 0.040). Following multivariate analysis, the only factor independently associated with poor prognosis in the surgically treated subgroup was a poor clinical status (mRS 3–5) at admission (OR: 96.14; 95% CI: 5.15–1793.9; p = 0.002).ConclusionsManagement of posterior fossa AVMs is challenging, and patients who present with ruptured AVMs often have a poor clinical status at admission leading to a poor prognosis. Therefore, proper and timely management of these patients is essential.

Echocardiography-Guided Radiofrequency Ablation for Cardiac Tumors

BackgroundPatients with cardiac tumors may present challenges for surgical resection due to poor clinical condition. Echocardiography-guided transapical radiofrequency ablation for cardiac tumors (TARFACT) potentially offers a less invasive palliative therapy option. ObjectivesThis study aimed to evaluate the safety and efficacy of TARFACT. MethodsFive patients with cardiac tumors (mucinous liposarcoma, myocardial hypertrophy with inflammatory cell infiltration mass, fibrous tissue tumor hyperplasia, myocardial clear cell sarcoma, and cardiac rhabdomyoma) were included. All patients underwent TARFACT and were assessed with electrocardiogram, echocardiographic imaging, biochemical analysis, and pathological confirmation. ResultsThe median follow-up for all patients was 9 (range 4-12) months. Three surviving patients were alive at their last follow-up (9, 12, and 12 months, respectively), whereas 2 patients with late-stage tumors survived 6 months and 13 months after TARFACT, respectively. After TARFACT, all patients showed significant reductions in tumor size: the mean length decreased from 6.7 ± 2.0 cm to 4.7 ± 1.8 cm (P = 0.007); and the mean width decreased from 5.0 ± 2.1 cm to 2.5 ± 0.7 cm (P = 0.041). NYHA functional class also improved: median (IQR) decreased from 3.0 (1.5) to 2.0 (1.0) (P = 0.038), Peak E-wave on echocardiography showed a mean increase from 64.4 ± 15.7 cm/s to 76.6 ± 18.6 cm/s (P = 0.008), and NT-pro BNP levels had a median (IQR) reduction from 115.7 (252.1) pg/mL to 55.0 (121.6) pg/mL (P = 0.043). ConclusionsTARFACT is a novel palliative treatment option for cardiac tumors, reducing accessible tumors and improving clinical symptoms in a preliminary group of patients.

Bridge to transplant in single-ventricle anatomy: subpulmonary support with EXCOR ventricular assist device associated with pulmonary artery reconstruction.

Patients with a single ventricle circulation continue to be a challenge for a heart transplant. The patients in this cohort, often in poor clinical condition with frequent hepatic and renal impairment having undergone previous multiple surgical procedures, are often allosensitive and consequently have an increased risk of post-transplant complications. Although the most recently published series results are improved, this group of patients, with preserved ventricular function, continues to have a higher mortality rate. Moreover, the operation can be complicated by anatomical differences among the pulmonary arteries. This case report presents a child with tricuspid atresia and pulmonary vascular resistance contraindicating Fontan surgery, unfavourable anatomy of the central pulmonary arteries and in poor clinical condition. An EXCOR ventricular assist device (Berlin Heart) was used for sub- pulmonary mechanical circulatory support and pulmonary bifurcation reconstruction, as a bridge to a transplant.

Factors to improve odds of success following medial opening-wedge high tibial osteotomy: a machine learning analysis

BackgroundAlthough high tibial osteotomy (HTO) is an established treatment option for medial compartment osteoarthritis, predictive factors for HTO treatment success remain unclear. This study aimed to identify informative variables associated with HTO treatment success and to develop and internally validate machine learning algorithms to predict which patients will achieve HTO treatment success for medial compartmental osteoarthritis.MethodsThis study retrospectively reviewed patients who underwent medial opening-wedge HTO (MOWHTO) at our center between March 2010 and December 2015. The primary outcomes were a lack of conversion to total knee arthroplasty (TKA) and achievement of a minimal clinically important difference of improvement in the Knee Injury and Osteoarthritis Outcome Score (KOOS) at a minimum of five years postoperatively. Recursive feature selection was used to identify the combination of variables from an initial pool of 25 features that optimized model performance. Five machine learning algorithms (XGBoost, multilayer perception, support vector machine, elastic-net penalized logistic regression, and random forest) were trained using five-fold cross-validation three times and applied to an independent test set of patients. The performance of the model was evaluated by the area under the receiver operating characteristic curve (AUC).ResultsA total of 231 patients were included, and 200 patients (86.6%) achieved treatment success at the mean of 9 years of follow-up. A combination of seven variables optimized algorithm performance, and the following specific cutoffs increased the likelihood of MOWHTO treatment success: body mass index (BMI) ≤ 26.8 kg/m2, preoperative KOOS for pain ≤ 46.0, preoperative KOOS for quality of life ≤ 33.0, preoperative International Knee Documentation Committee score ≤ 42.0, preoperative Short-Form 36 questionnaire (SF-36) score > 42.25, three-month postoperative hip-knee-ankle angle > 1.0°, and three-month postoperative medial proximal tibial angle (MPTA) > 91.5° and ≤ 94.7°. The random forest model demonstrated the best performance (F1 score: 0.93; AUC: 0.81) and was transformed into an online application as an educational tool to demonstrate the capabilities of machine learning.ConclusionsThe random forest machine learning algorithm best predicted MOWHTO treatment success. Patients with a lower BMI, poor clinical status, slight valgus overcorrection, and postoperative MPTA < 94.7 more frequently achieved a greater likelihood of treatment success.Level of evidenceLevel III, retrospective cohort study.

Navigating Uncertain Waters: First-Trimester Screening's Role in Identifying Neonatal Complications.

Background: Contemporary diagnostic methods aimed at assessing neonatal outcomes predominantly rely on the medical history of pregnant women. Ideally, universal biomarkers indicating an increased risk of delivering infants in poor clinical condition, with a heightened likelihood of requiring hospitalization in a Neonatal Intensive Care Unit (NICU), would be beneficial for appropriately stratifying pregnant women into a high-risk category. Our study evaluated whether biochemical and ultrasonographical markers universally used in first-trimester screenings for non-heritable chromosomal aberrations could serve this purpose. Methods: This study encompassed 1164 patients who underwent first-trimester screening, including patient history, ultrasound examinations, and biochemical tests for pregnancy-associated plasma protein-A (PAPP-A) and the free beta-HCG subunit (fbHCG), from January 2019 to December 2021. The research concentrated on the correlation between these prenatal test results and neonatal outcomes, particularly Apgar scores, umbilical blood pH levels, and the necessity for NICU admission. Results: In our cohort, neonates scoring lower than 8 on the Apgar scale at birth exhibited lower concentrations of PAPP-A in the first trimester, both in raw and normalized values (PAPP-A MoM 0.93 vs. 1.027, p = 0.032). We also observed a higher pulsatility index in the venous duct in the first trimester in full-term neonates born with <8 points on the Apgar scale. Additionally, newborns born with an umbilical blood pH < 7.2 had lower normalized first-trimester PAPP-A concentrations (0.69 vs. 1.01 MoM, p = 0.04). We also noted that neonates requiring NICU hospitalization post-delivery had lower first-trimester bHCG concentrations (0.93 MoM vs. 1.11 MoM, p = 0.03). However, none of the correlations in our study translated into a robust prognostic ability for predicting dichotomous outcomes. All areas under the curve achieved a value < 0.7. Conclusions: Low concentrations of PAPP-A and free bHCG subunit in the first trimester may be associated with poorer clinical and biochemical conditions in neonates post-delivery. However, the relationship is weak and has limited predictive capability. Further research evaluating these relationships is necessary for the appropriate stratification of pregnant women into high-risk categories for neonatological complications.
