Spontaneous Systemic Tumor Embolism Caused by Tumor Invasion of Pulmonary Vein in a Patient with Advanced Lung Cancer

We describe a 72-year-old man who presented with left hemiparesis due to acute cerebral infarction in the right fronto-temporal lobe. Three months prior to admission, he was hospitalized for right hemiparesis due to the acute cerebral infarction in the left anterior cerebral artery territory. To investigate the cause of his recurrent embolic event, a chest computed tomography scan and echocardiography were performed, which revealed advanced lung cancer invading contiguously through the pulmonary veins to the right main pulmonary artery and left atrium. Tumor embolism is a rare cause of stroke, occurring with primary or metastatic neoplasms of the lung. Echocardiography is a useful tool in patients with cerebral embolic episodes

Epidermal growth factor receptor mutations and anaplastic lymphoma kinase rearrangements in lung cancer with nodular ground-glass opacity

Vår uppsats handlar om formativ bedömning och vad det innebär att arbeta så i undervisningen. Vi tolkar att rådande läroplaner beskriver ett uppdrag som ligger i linje med ett formativt arbetssätt. Syftet var att ta reda på om lärare i samhällskunskap som arbetar på gymnasiet arbetar formativt och hur de gör det. Ett annat vanligt namn för formativ bedömning är bedömning för lärande (BFL). Genom kvalitativa intervjuer har vi frågat gymnasielärare i samhällskunskap hur de arbetar med bedömning, om de arbetar formativt och om det finns någon samsyn på deras respektive gymnasieskolor kring bedömning. Vi ville också veta vad formativt arbete innebär. Bedömning för lärande fokuserar på lärandet och hur eleven kan utvecklas och nå framgång i lärandet. Genom att konkretisera mål, syfte och kunskapskvaliteter så att eleven förstår dessa kan eleven få syn på sitt eget lärande. När eleven ges makt över sitt eget lärande leder det till ökad motivation. I formativ bedömning arbetar läraren bland annat med feedback och kamrat- och självvärdering. Vårt resultat visar att lärarna vi intervjuat i stor utsträckning arbetar summativt med formativa inslag i varierande grad, förutom en av lärarna som arbetar på en gymnasieskola i Borås som arbetar enligt bedömning för lärande. Studien visar att det råder brist på samsyn kring bedömning på gymnasie-skolorna, förutom på skolan i Borås där det finns tid avsatt för möten och samtal kring formativ bedömning. Litteraturen visar på de positiva effekterna av bedömning för lärande vilket också styrks av intervjun med läraren i Borås

Comparison of the outcomes between sorafenib and lenvatinib as the first-line systemic treatment for HBV-associated hepatocellular carcinoma: a propensity score matching analysis

In a randomized controlled trial, lenvatinib was non-inferior to sorafenib in overall survival (OS) of patients with unresectable hepatocellular carcinoma (uHCC). This study aimed to compare the effects of sorafenib and lenvatinib as first-line systemic therapy against uHCC with real-world data in chronic hepatitis B patients. This retrospective single-center study involved 132 patients with HBV-related uHCC. Propensity score matching (PSM) was used to balance the baseline characteristics, including age, sex, serum alpha-fetoprotein levels, Child–Pugh class, tumor size, and tumor stage. The primary endpoint was overall survival (OS), and the secondary endpoints included progression-free survival (PFS), time to progression (TTP), and tumor response. After PSM, the final analysis included 44 patients treated with lenvatinib and 88 with sorafenib. The OS (7.0 vs 9.2months, p = 0.070) and PFS (4.6 vs 2.4months, p = 0.134) were comparable between the two drugs. Multivariable analysis showed that lenvatinib and sorafenib were not independent prognostic factors of OS (adjusted hazard ratio = 1.41, 95% confidence interval = 0.96–2.08, p = 0.077) after adjustment for baseline alpha-fetoprotein levels, total bilirubin levels, alanine aminotransferase level, performance status, tumor stage, and tumor size. However, the lenvatinib group had a significantly prolonged TTP (5.2 vs 2.5months, p = 0.018) and a higher objective response rate (18.2% vs 4.5%, p = 0.020) and disease control rate (77.3% vs 47.7%, p = 0.001) than the sorafenib group. Our study demonstrated that lenvatinib had a comparable OS and PFS but longer TTP and better tumor response compared to sorafenib in patients with HBV-related uHCC

Clinical features and long-term prognosis of acute fibrinous and organizing pneumonia histologically confirmed by surgical lung biopsy

Abstract Background Acute fibrinous and organizing pneumonia (AFOP) is a rare interstitial pneumonia characterized by intra-alveolar fibrin deposition and organizing pneumonia. The clinical manifestations and long-term prognosis of AFOP are unclear. Our objective was to investigate the clinical features and prognosis of AFOP. Methods We identified patients diagnosed with AFOP by surgical lung biopsy between January 2011 and May 2018 at Seoul National University Bundang Hospital. We retrospectively reviewed clinical and radiologic findings, treatment, and outcomes of AFOP. Results Fifteen patients with histologically confirmed lung biopsies were included. The median follow-up duration was 2.4 (range, 0.1–82) months. The median age was 55 (range, 33–75) years, and four patients were immunocompromised. Fever was the most common clinical presentation (86.7%). Patchy ground-glass opacities and/or consolidations were the most predominant findings on chest computed tomography images. Nine patients (60%) received mechanical ventilator care, and eight patients (53.3%) died. The non-survivors tended to have slightly higher body mass index (BMI) and a long interval between symptom onset and diagnosis than the survivors, but these findings were not statistically significant. Among seven survivors, five patients were discharged without dyspnea and oxygen supplement. Conclusions The clinical course of AFOP was variable. Although AFOP was fatal, most of the patients who recovered from AFOP maintained normal life without supplemental oxygen therapy and respiratory symptoms

Drug-Eluting Stenting Followed by Cilostazol Treatment Reduces Late Restenosis in Patients With Diabetes Mellitus The DECLARE-DIABETES Trial (A Randomized Comparison of Triple Antiplatelet Therapy With Dual Antiplatelet Therapy After Drug-Eluting Stent Implantation in Diabetic Patients)

ObjectivesWe sought to evaluate the impact of cilostazol on neointimal hyperplasia after drug-eluting stent (DES) implantation in patients with diabetes mellitus (DM).BackgroundAlthough cilostazol has reduced the extent of neointimal hyperplasia and restenosis in patients after bare-metal stent implantation, it is not known whether this effect occurs after DES implantation in diabetic patients.MethodsThis randomized, multicenter, prospective study compared triple antiplatelet therapy (aspirin, clopidogrel, and cilostazol, triple group, n = 200) and dual antiplatelet therapy (aspirin and clopidogrel, standard group, n = 200) for 6 months in patients with DM receiving DES. The primary end point was in-stent late loss at 6 months.ResultsThe 2 groups had similar baseline clinical and angiographic characteristics. The in-stent (0.25 ± 0.53 mm vs. 0.38 ± 0.54 mm, p = 0.025) and in-segment (0.42 ± 0.50 mm vs. 0.53 ± 0.49 mm, p = 0.031) late loss were significantly lower in the triple versus standard group, as were 6-month in-segment restenosis (8.0% vs. 15.6%, p = 0.033) and 9-month target lesion revascularization (TLR) (2.5% vs. 7.0%, p = 0.034). At 9 months, major adverse cardiac events, including death, myocardial infarction, and TLR, tended to be lower in the triple than in the standard group (3.0% vs. 7.0%, p = 0.066). Multivariate analysis showed that sirolimus-eluting stents and the use of cilostazol were strong predictors of reduced restenosis or TLR.ConclusionsTriple antiplatelet therapy after DES implantation decreased angiographic restenosis and extent of late loss, resulting in a reduced risk of 9-month TLR compared with dual antiplatelet therapy in diabetic patients

Hemo-metabolic impairment in patients with ST-segment elevation myocardial infarction: Data from the INTERSTELLAR registry

Background: Not only hemo-dynamic (HD) factors but also hemo-metabolic (HM) risk factors reflecting multi-organ injuries are considered as important prognostic factors in ST-segment elevation myocardial infarction (STEMI). However, studies regarding HM risk factors in STEMI patients are currently limited. Method: Under analysis were 1,524 patients with STEMI who underwent primary percutaneous coronary intervention in the INTERSTELLAR registry. Patients were divided into HM (≥ 2 risk factors) and non-HM impairment groups. The primary outcome was in-hospital all-cause mortality, and the secondary outcome was 1-year all-cause mortality. Results: Of 1,524 patients, 214 (14.0%) and 1,310 (86.0%) patients were in the HM and non-HM impairment groups, respectively. Patients with HM impairment had a higher incidence of in-hospital mortality than those without (24.3% vs. 2.7%, p < 0.001). After adjusting for confounders, HM impairment was independently associated with in-hospital mortality (inverse probability of treatment weighting [IPTW]-adjusted odds ratio: 1.81, 95% confidence interval: 1.08–3.14). In the third door-to-balloon (DTB) time tertile (≥ 82 min), HM impairment was strongly associated with in-hospital mortality. In the first DTB time tertile ( < 62 min), indicating relatively rapid revascularization, HM impairment was consistently associated with increased in-hospital mortality. Conclusions: Hemo-metabolic impairment is significantly associated with increased risk of in-hospital and 1-year mortality in patients with STEMI. It remains a significant prognostic factor, regardless of DTB time
