BACKGROUND: Invasive lobular carcinoma (ILC) is known to be the second most common histological type following invasive ductal carcinoma (IDC). Definitive clinical features of ILC are controversial. METHODS: We retrospectively analyzed a cohort of 330 patients with metastatic breast cancer, 303 of IDC, 19 of ILC, and 8 of others. We compared the patient age and tumor-node-metastasis factors, disease-free survival (DFS), estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 (HER2) expression at the primary site between ILC and IDC...

OBJECTIVES: The surgical approach to chronic pleural empyema is still controversial. Video-assisted thoracic surgery (VATS) debridement and decortication has shown favourable outcomes, while the uniportal VATS (U-VATS) approach is still anecdotal. We report our experience with ultrasonographic (US) preoperative staging followed by U-VATS decortication for pleural empyema. METHODS: We performed a retrospective analysis of patients who underwent surgical treatment of stage II and stage III pleural empyema from 2012 to 2015...

OBJECTIVES: In patients with acute aortic dissection involving the arch and the descending aorta (AADA DeBakey type I), performing a total aortic arch replacement with the frozen elephant trunk (FET) procedure for supposedly better long-term results is still controversial. METHODS: From February 2004 to April 2016, 94 patients with AADA DeBakey type I had an FET procedure (80% men, age 58 ± 12 years). During the early period (Group 1, 2004-10), the FET technique was performed using non-branched grafts...

: Seeing one's own body has been reported to have analgesic properties. Analgesia has also been described when seeing an embodied virtual body co-located with the real one. However, there is a controversy regarding whether this effect holds true when seeing an illusory-owned body part, such as during the rubber-hand illusion. A critical difference between these paradigms is the distance between real and surrogate body part. Co-location of real arm and surrogate is possible in an immersive virtual environment, but not during illusory ownership of a rubber arm...

BACKGROUND: Beta-blockers refer to a mixed group of drugs with diverse pharmacodynamic and pharmacokinetic properties. They have shown long-term beneficial effects on mortality and cardiovascular disease (CVD) when used in people with heart failure or acute myocardial infarction. Beta-blockers were thought to have similar beneficial effects when used as first-line therapy for hypertension. However, the benefit of beta-blockers as first-line therapy for hypertension without compelling indications is controversial...

Cannabis (hemp and marijuana) is an iconic yet controversial crop. On the one hand, it represents a growing market for pharmaceutical and agricultural sectors. On the other hand, plants synthesizing the psychoactive THC produce the most widespread illicit drug in the world. Yet, the difficulty to reliably distinguish between Cannabis varieties based on morphological or biochemical criteria impedes the development of promising industrial programs and hinders the fight against narcotrafficking. Genetics offers an appropriate alternative to characterize drug vs...

Decreased levels of endogenous hydrogen sulfide (H2S) contribute to atherosclerosis, whereas equivocal data are available on H2S effects during sepsis. Moreover, H2S improved glucose utilization in anaesthetized, ventilated, hypothermic mice, but normothermia and/or sepsis blunted this effect. The metabolic effects of H2S in large animals are controversial. Therefore, we investigated the effects of the H2S donor GYY4137 during resuscitated, fecal peritonitis-induced septic shock in swine with genetically and diet-induced coronary artery disease (CAD)...

Ultrafast energy dissipation is a crucial factor for the photostability of DNA and RNA, but even some of the key electronic deactivation pathways in monomeric nucleic acid building stones are still controversial. Here, we report on the excited-state dynamics of the rare nucleotide xanthosine monophosphate as a function of deprotonation state (XMP vs. XMP - ) and excitation wavelength ( λ pump = 278-243 nm) by femtosecond time-resolved fluorescence and absorption spectroscopy. We show that the predominating relaxation channel leads to a return of the photo-excited molecules to the electronic ground state in τ∼1 ps...

Poor vitamin D status has been associated with increased risk and severity of respiratory tract infections. Whether or not inflammation and infection affects 25-hydroxy vitamin D (25(OH)D) concentration is controversial and is important in the interpretation of observational studies using plasma-25(OH)D as a biomarker for status. Our objectives were to measure whether 25(OH)D concentration was altered by an episode of acute lower respiratory tract infection and whether markers of inflammation predicted the 25(OH)D concentration...

INTRODUCTION: Treatment of moderate to severe slipped capital femoral epiphysis (SCFE) is controversial. Over the last years, 3 institutions in Argentina adopted the modified Dunn procedure for capital realignment in selected cases of SCFE. Our aim in this study was to evaluate the clinical outcome and the rate of complications of patients who had undergone surgical hip dislocation and capital realignment. METHODS: A multicenter retrospective cohort study of patients who received the modified Dunn procedure from January 2009 to 2013 was performed...

PURPOSE OF REVIEW: Despite nerve-sparing surgery, postoperative shoulder morbidity remains high and significantly impacts patient's quality of life. This review will focus on recent findings of anatomical nuances of the cranial nerve XI (CN XI) along its course in the neck and possible reasons for postoperative morbidity. RECENT FINDINGS: The most recent studies identified three different branching patterns of the CN XI in the neck. In type 1 (66%), the branch for trapezius muscle exits at the posterior border of the sternocleidomastoid muscle (mSCM)...

Atrial fibrillation is the most prevalent cardiac arrhythmia, affecting 10% of those aged over 80 years. Despite multiple treatment options, it remains an independent prognostic marker of mortality due to its association with clinical sequelae, particularly cerebrovascular events. Management can be broadly divided into treatment of the arrhythmia, via rhythm or rate control, and stroke thromboprophylaxis via anticoagulation. Traditional options for pharmacotherapy include negatively chronotropic drugs such as β-blockers, and/or arrhythmia-modifying drugs such as amiodarone...

BACKGROUND: The decision to hospitalize or not patients with acute pulmonary embolism (PE) is controversial. Despite the advantages of close monitoring, hospitalization by itself may lead to in-hospital complications and potentially worsen the prognosis of PE patients. OBJECTIVES: To determine the net clinical benefit of hospitalization versus outpatient management of normotensive patients with acute pulmonary embolism (PE). METHODS: Retrospective cohort propensity score analysis (radius marching with replacement)...

This article analyzes the debate about data acquisition and assessment in health claims regulation by identifying the underlying controversies on methodological choice. Regulation in the European Union imposes the need for a scientific substantiation of all health claims (claims about a relationship between consumption of certain food ingredients and positive health effects). Randomized controlled trials (RCTs) are the method that generally is considered to provide the highest quality data for decision making in claims regulation because they allow for establishing cause-effect relationships...

The grey wolf (Canis lupus) is one of the most widely distributed terrestrial mammals, and its distribution and ecology in Europe and North America are largely well described. However, the distribution of grey wolf in southern China is still highly controversial. Several well-known western literatures stated that there are no grey wolves in southern China, while the presence of grey wolf across China has been indicated in A Guide to the Mammals of China, published by Princeton University Press. It is essential to solve this discrepancy since dogs may have originated from grey wolfs in southern China...

Affective coldness is one of the main features of Machiavellianism. Recent studies have revealed that Machiavellians are emotionally detached and that this "affective blunting" is associated with intense feelings, emotional instability, negative emotions, and difficulty in enduring distress. We used brain-imaging techniques to investigate emotion regulation in Machiavellianism at a neuropsychological level. We used situations in which participants were required to demonstrate emotional flexibility to explore the controversy surrounding the fact that Machiavellianism is associated with both cold-mindedness and emotional instability...
