From a distinctive sign to an exchangeable asset: exploring the U.S. market for trademark licensing
A remarkable growth in the value of trademark licensing has been recently recorded. Our paper contributes to the understanding of this under-explored phenomenon using a dataset newly released by the USPTO. Our study analyses the evolution of licensing activities in the U.S. during the 2003-2017 period, the characteristics of these trademarks and agreements, and certain features of the licensing parties involved. We found that licensing activities varied considerably during these years. They were usually signed between two parties only, and, on average, they involved more than one trademark. Excluding under-reporting effect, the analyses reveal that a large portion of heterogeneity in licensing activity is due to the NICE international classes associated with each trademark. Indeed, trademark licensing agreements appear to be unevenly distributed across these classes, suggesting that this activity and the way it is carried out is correlated with the market to which the licensed trademark refers
Long‑term Effectiveness and Safety of Upadacitinib for Atopic Dermatitis in a Real‑world Setting: An Interim Analysis Through 48 Weeks of Observation
Background Janus kinase (JAK) inhibitors, including upadacitinib, have been recently approved for the treatment of moderate- severe atopic dermatitis (AD) and real-world data on upadacitinib effectiveness and safety are limited. This interim analysis aimed to assess effectiveness and safety of upadacitinib throughout 48 weeks of observation in a real-world adult AD population. Methods This prospective study collected data on adult patients affected by moderate-to-severe AD and treated with upadacitinib at the dosage of either 15 mg or 30 mg daily based on the physician decision. Upadacitinib was prescribed in the context of a national compassionate use programme. In this interim analysis, within patient comparisons of continuous scores of different scales (namely Eczema Area and Severity Index [EASI], body surface area [BSA], Dermatology Life Quality Index [DLQI], Patient Oriented Eczema Measure [POEM], Numeric Rating Scale [NRS] subtests) were performed. The percentage of patients achieving EASI 75, EASI 90 and EASI 100 at Week 16, 32 and 48 was also evaluated. Results One hundred and forty-six patients were included in the analysis. Upadacitinib 15 mg or 30 mg daily was prescribed as monotherapy in most cases (127/146, 87.0%). Upadacitinib was initially prescribed at the dosage of 30 mg daily in 118 of 146 (80.8%) patients and 15 mg daily in 28/146 (19.2%) patients. A significant improvement in the clinical signs and symptoms of AD was detected by Week 16 and throughout the study period. EASI 75, EASI 90 and EASI 100 responses were achieved by 87.6%, 69.1% and 44.3% at Week 48, associated with a sustained reduction in the mean values of all physicianreported (EASI and BSA) and patient-reported (Itch- Sleep- and Pain-NRS, DLQI, and POEM) disease severity outcomes, up to 48 weeks of treatment. Treatment response observed in 15 mg upadacitinib-treated patients was comparable with that detected in 30 mg upadacitinib-treated patients, revealing no statistical difference between the two patient sub-cohorts. Through the observation period, dose reduction or escalation was observed in 38/146 (26%) of treated cases. Overall, 26 of 146 (17.8%) patients experienced at least one adverse event (AE) during the treatment period. In total, 29 AEs were recorded and most of them were evaluated as mild to moderate, while in 4 cases the occurrence of AE led to drug discontinuation, for a total of 7/146 (4.8%) dropouts. Conclusion This study provides strong evidence of a sustained response obtained by upadacitinib in AD patients, who had failed to respond to conventional or biological systemic agents, through 48 weeks of observation. Upadacitinib was also demonstrated to be advantageous in terms of flexibility in dose reduction or escalation as upadacitinib dose was shaped on clinical needs that, in a real-world setting, might frequently change
Self-administration of omalizumab: why not? A literature review and expert opinion
Introduction: Omalizumab is used to treat severe uncontrolled allergic asthma and chronic spontaneous urticaria (CSU), and is approved for self-administration in prefilled syringes. It is thus important to understand the advantages, critical issues, and indications for home administration.Areas covered: The present review summarizes the available evidence on home administration of omalizumab in asthma and CSU to illustrate the advantages derived from self-administration of patients in this setting.Expert opinion: The available data suggest that patients can safely administer biologics at home with suitable training, and that home administration is time saving and cost-effective. The majority of patients with severe asthma or CSU treated with omalizumab are likely to be suitable candidates for self-administration, which can be proposed to anyone that the clinician deems suitable. In addition to clinicians, pharmacists can also play a key role in managing patients who are prescribed home administration. A practical flow chart is proposed on selection of patients and their management during home administration. Self-administration of biologics can be considered as a valid alternative to traditional injections in a clinical setting, and the evidence has shown that no major issues need to be overcome in terms of safety or efficacy
SKATE: A Natural Language Interface for Encoding Structured Knowledge
In Natural Language (NL) applications, there is often a mismatch between what
the NL interface is capable of interpreting and what a lay user knows how to
express. This work describes a novel natural language interface that reduces
this mismatch by refining natural language input through successive,
automatically generated semi-structured templates. In this paper we describe
how our approach, called SKATE, uses a neural semantic parser to parse NL input
and suggest semi-structured templates, which are recursively filled to produce
fully structured interpretations. We also show how SKATE integrates with a
neural rule-generation model to interactively suggest and acquire commonsense
knowledge. We provide a preliminary coverage analysis of SKATE for the task of
story understanding, and then describe a current business use-case of the tool
in a specific domain: COVID-19 policy design.Comment: Accepted at IAAI-2
Blood Pressure Target Achievement Under Monotheraphy. A Real-Life Appraisal
Introduction: Despite hypertension guidelines suggest that the most effective treatment strategy to improve blood pressure (BP) target achievement is to implement the use of combination treatment, monotherapy is still widely used in the clinical practice of hypertension.
Aim: To investigate BP control under monotherapy in the setting of real-life.
Methods: We extracted data from a medical database of adult outpatients who were referred to the Hypertension Unit, Sant'Andrea Hospital, Rome (IT), including anthropometric data, CV risk factors and comorbidities, presence or absence of antihypertensive therapy and concomitant medications. Among treated hypertensive patients, we identified only those under single antihypertensive agent (monotherapy). Office BP treatment targets were defined according to 2018 ESC/ESH guidelines as: (a) < 130/80 mmHg in individuals aged 18-65 years; (b) < 140/80 mmHg in those aged > 65 years.
Results: From an overall sample of 7797 records we selected 1578 (20.2%) hypertensive outpatients (47.3% female, age 59.5 ± 13.6 years, BMI 26.6 ± 4.4 kg/m2) treated with monotherapies, among whom 30.5% received ACE inhibitors, 37.7% ARBs, 15.8% beta-blockers, 10.6% CCBs, 3.0% diuretics, and 2.0% alpha-blockers. 36.6% of these patients reached the conventional clinic BP goal of < 140/90 mmHg, whilst the 2018 European guidelines BP treatment targets were fulfilled only in 14.0%. In particular, 10.2% patients aged 18-65 years and 20.4% of those aged > 65 years achieved the recommended BP goals. All these proportions results significantly lower than those achieved with dual (18.2%) or triple (22.2%) combination therapy, though higher than those obtained with life-style changes (10.8%). Proportions of patients on monotherapies with normal home and 24-h BP levels were 22.0% and 30.2%, respectively, though only 5.2% and 7.3% of these patients achieved sustained BP control, respectively. Ageing and dyslipidaemia showed significant and independent positive predictive value for the achievement of the recommended BP treatment targets, whereas European SCORE resulted a negative and independent predictor in outpatients treated with monotherapies.
Conclusions: Our data showed a persistent use of monotherapy in the clinical practice, though with unsatisfactory BP control, especially in light of the BP treatment targets suggested by the last hypertension guidelines
Lipid Peroxidation and Depressed Mood in Community-Dwelling Older Men and Women
It has been hypothesized that cellular damage caused by oxidative stress is associated with late-life depression but\ud
epidemiological evidence is limited. In the present study we evaluated the association between urinary 8-iso-prostaglandin\ud
F2a (8-iso-PGF2a), a biomarker of lipid peroxidation, and depressed mood in a large sample of community-dwelling older\ud
adults. Participants were selected from the Health, Aging and Body Composition study, a community-based longitudinal\ud
study of older persons (aged 70–79 years). The present analyses was based on a subsample of 1027 men and 948 women\ud
free of mobility disability. Urinary concentration of 8-iso-PGF2a was measured by radioimmunoassay methods and adjusted\ud
for urinary creatinine. Depressed mood was defined as a score greater than 5 on the 15-item Geriatric Depression Scale and/\ud
or use of antidepressant medications. Depressed mood was present in 3.0% of men and 5.5% of women. Depressed men\ud
presented higher urinary concentrations of 8-iso-PGF2a than non-depressed men even after adjustment for multiple\ud
sociodemographic, lifestyle and health factors (p=0.03, Cohen’s d = 0.30). This association was not present in women\ud
(depressed status-by-sex interaction p = 0.04). Our study showed that oxidative damage may be linked to depression in\ud
older men from a large sample of the general population. Further studies are needed to explore whether the modulation of\ud
oxidative stress may break down the link between late-life depression and its deleterious health consequences
Early cardiac abnormalities and increased C-reactive protein levels in a cohort of children with sleep disordered breathing
This study aims to evaluate left ventricular (LV) structure and function and inflammation in a paediatric population with sleep disordered breathing (SDB) and in control subjects. Forty-nine children with SDB and 21 healthy, age-matched subjects were enrolled. The diagnosis of obstructive sleep apnoea syndrome (OSAS) was confirmed by the laboratory polysomnography, showing an obstructive apnoea/hypopnoea index of more than one per hour, according to the criteria of the American Academy of Sleep Medicine and modified for paediatric population. Fasting blood samples for the biochemical evaluation (including high-sensitivity C-reactive protein (hsCRP) were drawn in the morning, after the polysomnographic examination in all patients with SDB and in the control group. All children underwent a two-dimensional colour Doppler cardiac examination with LV mass assessment and systolic and diastolic function evaluation. Higher hsCRP levels were observed in subjects with OSAS than in children with primary snoring and in controls (0.8 +/- 0.7 vs 0.3 +/- 0.1 ng/dl, p = 0.001, and 0.4 +/- 0.2 ng/dl, p = 0.01, respectively). The LV diastolic dysfunction was significantly more frequent in patients with severe OSAS and higher hsCRP levels than in control group. This study shows that OSAS in children is associated with higher LV mass, early LV diastolic dysfunction and a pro-inflammatory state (high CRP levels). These findings might help to explain the higher incidence of cardiovascular morbidity in patients with OSAS
Preliminary assessment of fentanyl and synthetic opioids prevalence among addiction patients by means of hair analysis
Background Although the diffusion of novel synthetic opioids has become a worldwide phenomenon, their prevalence of use in Italy seems to be limited. Existing national data is mainly derived by anamnestic surveyslacking of toxicological validation and not always disclosing the use of these compounds, which might remain under-diagnosed. Methods an assessment of the metabolites of the main synthetic opioids on hair samples was carried out among patients admitted at the Addiction Treatment Unit of Trento. The analytical approach included: (a) screening by means of immunoenzymatic method for fentanyl, fentanyl analogs and oxicodone; (b) confirmation of the samples resulted positive for fentanyl and oxicodone by means of HPLC-MS/; (c) search and dosage detection of Tramadol by means of HPLC-MS/MS. Results 3 out of 309 analysed samples were found positive: one was positive to Fentanyl and two to 4-ANPP. In the same cohort, 6 samples were also found positive for Oxycodone . Tramadol was searched in 189 samples and 12 of them resulted positive. Discussion and conclusion Those found positive were mainly young adults engaging in dangerous patterns of use and lacking awareness of risks. The phenomenon requires further consideration by health professionals. Training and more evidence-based information on synthetic opioids as well as other Novel Psychoactive Substances (NPS) are urgently needed.Peer reviewe
Disease burden affects aging brain function
BACKGROUND: Most older adults live with multiple chronic disease conditions, yet the effect of multiple diseases on brain function remains unclear.
METHODS: We examine the relationship between disease multimorbidity and brain activity using regional cerebral blood flow (rCBF) 15O-water PET scans from 97 cognitively normal participants (mean baseline age 76.5) in the Baltimore Longitudinal Study of Aging (BLSA). Multimorbidity index scores, generated from the presence of 13 health conditions, were correlated with PET data at baseline and in longitudinal change (n = 74) over 5.05 (2.74 SD) years.
RESULTS: At baseline, voxel-based analysis showed that higher multimorbidity scores were associated with lower relative activity in orbitofrontal, superior frontal, temporal pole and parahippocampal regions, and greater activity in lateral temporal, occipital, and cerebellar regions. Examination of the individual health conditions comprising the index score showed hypertension and chronic kidney disease individually contributed to the overall multimorbidity pattern of altered activity. Longitudinally, both increases and decreases in activity were seen in relation to increasing multimorbidity over time. These associations were identified in orbitofrontal, lateral temporal, brainstem, and cerebellar areas.
CONCLUSION: Together, these results show that greater multimorbidity is associated with widespread areas of altered brain activity, supporting a link between health and changes in aging brain function
