Semantic fluency tests are one of the key tests used in batteries for the early detection of Mild Cognitive Impairment (MCI) as the impairment in speech and semantic memory are among the first symptoms, attracting the attention of a large number of studies. Several new semantic categories and variables capable of providing complementary information of clinical interest have been proposed to increase their effectiveness. However, this also extends the time required to complete all tests and get the overall diagnosis. Therefore, there is a need to reduce the number of tests in the batteries and thus the time spent on them while maintaining or increasing their effectiveness. This study used machine learning methods to determine the smallest and most efficient combination of semantic categories and variables to achieve this goal. We utilized a database containing 423 assessments from 141 subjects, with each subject having undergone three assessments spaced approximately one year apart. Subjects were categorized into three diagnostic groups: Healthy (if diagnosed as healthy in all three assessments), stable MCI (consistently diagnosed as MCI), and heterogeneous MCI (when exhibiting alternations between healthy and MCI diagnoses across assessments). We obtained that the most efficient combination to distinguish between these categories of semantic fluency tests included the animals and clothes semantic categories with the variables corrects, switching, clustering, and total clusters. This combination is ideal for scenarios that require a balance between time efficiency and diagnosis capability, such as population-based screenings.

BACKGROUND: Persistence on advanced therapies in ulcerative colitis (UC) is a useful real-world treatment performance measure. This study compared real-world persistence during the maintenance phase among advanced therapy-naïve and -experienced patients with UC initiated on ustekinumab or adalimumab.
METHODS: Claims data from the IQVIA PharMetrics® Plus de-identified database (01/01/2015-06/30/2022) were used to select adult patients with UC treated with ustekinumab or adalimumab based on the agent first initiated (index date) after 10/21/2019. Inverse probability of treatment weighting was used to balance cohorts on baseline characteristics. Persistence on the index agent (no gaps in days of supply of > 120 days for ustekinumab or > 60 days for adalimumab), persistence while corticosteroid-free, while on monotherapy, and persistence on the US labeled dose were described and compared during the 12-month period post-index using Kaplan-Meier analysis and Cox proportional hazards models. Outcomes were analyzed separately among advanced therapy-naïve and advanced therapy-experienced patients.
RESULTS: At 12 months post-index, advanced therapy-naïve patients receiving ustekinumab (n = 371) had higher persistence on the index agent [83.8% vs. 57.6%, hazard ratio (95% confidence interval) = 3.09 (2.29-4.16); p < 0.001), persistence while corticosteroid-free [2.00 (1.63-2.45); p < 0.001], persistence while on monotherapy [2.67 (2.07-3.44); p < 0.001], and persistence on the labeled dose [4.21 (2.76-6.44); p < 0.001] versus those receiving adalimumab (n = 1726). At 12 months post-index, advanced therapy-experienced patients receiving ustekinumab (n = 693) had higher persistence on the index agent [78.1% vs. 59.2%, 2.44 (1.82-3.26); p < 0.001], persistence while corticosteroid-free [1.24 (1.01-1.54); p = 0.0447], persistence while on monotherapy [2.53 (2.00-3.21); p < 0.001], and persistence on the labeled dose [4.77 (3.09-7.35); p < 0.001] versus those receiving adalimumab (n = 254).
CONCLUSIONS: This claims-based analysis demonstrated significantly higher treatment persistence, including persistence while corticosteroid-free, persistence while on monotherapy, and persistence on the labeled dose, among both advanced therapy-naïve and advanced therapy-experienced patients with UC initiated on ustekinumab compared to adalimumab.

UNASSIGNED: When considering changing hypnotic pharmacotherapy, lemborexant has attracted attention as a candidate due to its effectiveness and safety profile. However, few studies have investigated switching patterns in clinical practice.
UNASSIGNED: We conducted a retrospective cohort study using a nationwide claims database. Patients prescribed a single hypnotic who either subsequently switched to (switching cohort) or were additionally prescribed (add-on cohort) lemborexant between July 2020 and December 2021 were identified. Proportion of successful switching was defined as remaining on lemborexant alone or without any hypnotic at six months after lemborexant initiation.
UNASSIGNED: Success proportion was 70.1% in the switching cohort (n = 4,861) and 38.6% in the add-on cohort (n = 9,423). In the add-on cohort, success proportion was lower in patients with a hypnotic history of ≥180 days (31.4%) and in patients whose prescribed hypnotic was a benzodiazepine or non-benzodiazepine (31.5% and 37.6%, respectively).
UNASSIGNED: Proportion of successful switching was higher in patients who switched to lemborexant than in those who added lemborexant as a concomitant treatment. The lower success proportion in the add-on cohort might be related to clinically more severe insomnia, and/or a concomitant prescription of a benzodiazepine or non-benzodiazepine, from which discontinuation may be challenging.

The effect of the external electric field on the ground-state tautomerism in 8-(benzo[d]thiazol-2-yl)quinolin-7-ol has been studied by using density functional theory. The compound exists as an enol tautomer (off state) and under the influence of the external electric field a long-range intramolecular proton transfer can occur, placing the tautomeric proton at the quinolyl nitrogen atom (on state). This is a result of the much higher dipole moment of the end keto tautomer and indicates that the external electric field can be used to mimic the implicit solvent effect in tautomeric systems. In the excited state, the further stabilization of the most polar on state leads to a situation when the excited-state intramolecular proton transfer becomes impossible, limiting the intramolecular rotation to the conical intersection region.

BACKGROUND: This study compared the clinical effectiveness of switching from tumor necrosis factor inhibitor (TNFi) to upadacitinib (TNFi-UPA), another TNFi (TNFi-TNFi), or an advanced therapy with another mechanism of action (TNFi-other MOA) in patients with rheumatoid arthritis (RA).
METHODS: Data were drawn from the Adelphi RA Disease Specific Programme™, a cross-sectional survey administered to rheumatologists and their consulting patients in Germany, France, Italy, Spain, the UK, Japan, Canada, and the USA from May 2021 to January 2022. Patients who switched treatment from an initial TNFi were stratified by subsequent therapy of interest: TNFi-UPA, TNFi-TNFi, or TNFi-other MOA. Physician-reported clinical outcomes including disease activity (with formal DAS28 scoring available for 29% of patients) categorized as remission, low/moderate/high disease activity, as well as pain were recorded at initiation of current treatment and ≥ 6 months from treatment switch. Fatigue and treatment adherence were measured ≥ 6 months from treatment switch. Inverse-probability-weighted regression adjustment compared outcomes by subsequent class of therapy: TNFi-UPA versus TNFi-TNFi, or TNFi-UPA versus TNFi-other MOA.
RESULTS: Of 503 patients who switched from their first TNFi, 261 were in TNFi-UPA, 128 in TNFi-TNFi, and 114 in TNFi-other MOA groups. At the time of switch, most patients had moderate/high disease activity (TNFi-UPA: 73%; TNFi-TNFi: 52%; TNFi-other MOA: 60%). After adjustment for differences in characteristics at point of switch, patients in TNFi-UPA group (n = 261) were significantly more likely to achieve physician-reported remission (67.7% vs. 40.3%; p = 0.0015), no pain (55.7% vs. 25.4%; p = 0.0007), and complete adherence (60.0% vs. 34.2%; p = 0.0049) compared with patients in TNFi-TNFi group (n = 121). Similar findings were observed for TNFi-UPA versus TNFi-other MOA groups (n = 111).
CONCLUSIONS: Patients who switched from TNFi to UPA had significantly better clinical outcomes of remission, no pain, and complete adherence than those who cycled TNFi or switched to another MOA.

The reliance on student samples has long been a subject of debate in experimental approaches to studying behaviour. We contribute to this discussion by looking at differences in financial behaviour between a student and a non-student sample in three sets of lab experiments conducted in Spain, Germany and Poland (n=857). Participants from both samples switched more often and made better financial decisions after they received a message encouraging them to switch financial service providers. While the size of the effect on switching frequency was comparable between the two samples, the effect on switching quality was significantly stronger on non-students. Further analysis suggests this is due to a better performance of students before the prompt leaving less room for improvement by the reminder. Results suggest that experimental evidence derived from students should be generalized with caution.

UNASSIGNED: Biologic agents have demonstrated efficacy in treating ulcerative colitis (UC); however, treatment failure to tumor necrosis factor inhibitors (TNFi) is common in the real world. Data on preferential sequencing in clinical practice after failure remain limited.
UNASSIGNED: This study aimed to evaluate real-world outcomes of patients cycling to TNFis or switching to non-TNFi biologics following first-line failure with TNFis.
UNASSIGNED: Retrospective cohort study in Germany.
UNASSIGNED: Adult patients with UC were identified using administrative claims data from 1 May 2014 to 30 June 2022 provided by a statutory sickness fund. Patients newly initiating first-line therapy with TNFis and then switching to another agent were identified. Patients were defined as within-class switched (WCS), if they cycled to another TNFi, or outside-class switchers (OCS), if they switched to a non-TNFi biologic [ustekinumab (UST) or vedolizumab (VDZ)] and followed from index (switch date) to death, insurance end, or study end on 30 June 2022. Inverse probability of treatment weighting (IPTW) was performed to adjust for differences in baseline characteristics between groups, and weighted Cox regression models were used to compare primary (time to discontinuation and second treatment switch) and secondary outcomes (corticosteroid-free drug survival).
UNASSIGNED: We identified 166 patients initiating TNFis and switching to a subsequent treatment (mean age: 42.9 years, 49.4% female). Following IPTW, there were 71 and 76 patients in the WCS and OCS groups, respectively. Compared to OCS, WCS were more likely to discontinue the new therapy [hazard ratio (HR), 1.82, 95% confidence interval (CI), 1.14-2.89, p = 0.012], and switch a second time (HR, 3.46, 95% CI, 1.89-6.36, p < 0.001). Moreover, WCS showed an increased likelihood of initiating prolonged corticosteroid therapy (HR, 1.42, 95% CI, 0.77-2.59, p = 0.260); however, the results were not significant.
UNASSIGNED: Following first-line TNFi failure, this study suggests that real-world outcomes among patients with UC are less favorable when cycling to another TNFi, compared to switching to a non-TNFi such as UST or VDZ.

BACKGROUND: Both tenofovir alafenamide (TAF) and tenofovir disoproxil fumarate (TDF) are the first-line treatments for chronic hepatitis B (CHB). We have showed switching from TDF to TAF for 96 weeks resulted in further alanine aminotransferase (ALT) improvement, but data remain lacking on the long-term benefits of TDF switching to TAF on hepatic fibrosis.
OBJECTIVE: To assess the benefits of TDF switching to TAF for 3 years on ALT, aspartate aminotransferase (AST), and hepatic fibrosis improvement in patients with CHB.
METHODS: A single center retrospective study on 53 patients with CHB who were initially treated with TDF, then switched to TAF to determine dynamic patterns of ALT, AST, AST to platelet ratio index (APRI), fibrosis-4 (FIB-4) scores, and shear wave elastography (SWE) reading improvement at switching week 144, and the associated factors.
RESULTS: The mean age was 55 (28-80); 45.3%, males; 15.1%, clinical cirrhosis; mean baseline ALT, 24.8; AST, 25.7 U/L; APRI, 0.37; and FIB-4, 1.66. After 144 weeks TDF switching to TAF, mean ALT and AST were reduced to 19.7 and 21, respectively. From baseline to switching week 144, the rates of ALT and AST < 35 (male)/25 (female) and < 30 (male)/19 (female) were persistently increased; hepatic fibrosis was also improved by APRI < 0.5, from 79.2% to 96.2%; FIB-4 < 1.45, from 52.8% to 58.5%, respectively; mean APRI was reduced to 0.27; FIB-4, to 1.38; and mean SWE reading, from 7.05 to 6.30 kPa after a mean of 109 weeks switching. The renal function was stable and the frequency of patients with glomerular filtration rate > 60 mL/min was increased from 86.5% at baseline to 88.2% at switching week 144.
CONCLUSIONS: Our data confirmed that switching from TDF to TAF for 3 years results in not only persistent ALT/AST improvement, but also hepatic fibrosis improvement by APRI, FIB-4 scores, as well as SWE reading, the important clinical benefits of long-term hepatitis B virus antiviral treatment with TAF.

Background and Objectives: In this study, our objective was to assess and compare the changes in visual and structural outcomes among patients with neovascular age-related macular degeneration (nAMD) who were switched from intravitreal aflibercept (IVA) to either intravitreal brolucizumab (IVBr) or intravitreal faricimab (IVF) injections in a clinical setting. Materials and Methods: This observational clinical study included 20 eyes of 20 patients switched to brolucizumab and 15 eyes of 14 patients switched to faricimab from aflibercept in eyes with nAMD. We measured the structural outcome (central macular thickness (CMT)) and the visual outcome (best-corrected visual acuity (BCVA); logMAR) as follows: just before the most recent IVA injection (B0), one month after the most recent IVA injection (B1), just before the first IVBr or IVF injection (A0), one month after (A1) and three months after (A3) the first IVBr or IVF injection. Results: BCVA showed significant improvement at A1 (0.25 ± 0.34) and at A3 (0.19 ± 0.24) compared to A0 (0.38 ± 0.35) in the IVBr group (p = 0.0156, p = 0.0166, respectively). CMT (μm) was significantly thinner at A1 (IVBr: 240.55 ± 51.82, IVF: 234.91 ± 47.29) and at A3 (IVBr: 243.21 ± 76.15, IVF: 250.50 ± 72.61) compared to at A0 (IVBr: 303.55 ± 79.18, IVF: 270.33 ± 77.62) in the IVBr group (A1: p = 0.0093, A3: p = 0.0026) and in the IVF group (A1: p = 0.0161, A3: p = 0.0093). There was no significant difference in BCVA and CMT improvement observed between two groups at any time point (p > 0.05 for all). Conclusions: Switching from aflibercept to either brolucizumab or faricimab has a significant anatomical effect in eyes with nAMD and both treatments appear to be effective short-term treatment options. There is a trend towards greater visual improvements and reductions in CMT with brolucizumab.

UNASSIGNED: One strategy to mitigate progressive multifocal leukoencephalopathy (PML) risk is to switch to other highly effective disease-modifying therapies (DMTs). However, the optimal switch DMT following natalizumab (NTZ) discontinuation is yet to be determined.
UNASSIGNED: The objective of the study is to determine the most effective and tolerable DMTs to switch to following NTZ discontinuation due to John Cunningham virus (JCV) antibody positivity.
UNASSIGNED: This is a multicenter observational cohort study that included all stable relapsing-remitting multiple sclerosis (MS) patients who were treated with NTZ for at least 6 months before switching therapy due to JCV antibody positivity.
UNASSIGNED: Of 321 patients, 255 switched from NTZ to rituximab/ocrelizumab, 52 to fingolimod, and 14 to alemtuzumab, with higher annualized relapse rate (ARR) in fingolimod switchers (0.193) compared with rituximab/ocrelizumab or alemtuzumab (0.028 and 0.032, respectively). Fingolimod switchers also had increased disability progression (p = 0.014) and a higher proportion developed magnetic resonance imaging (MRI) lesions compared with rituximab/ocrelizumab (62.9% vs. 13.0%, p < 0.001, and 66.6% vs. 24.0%, p < 0.001, respectively). Mean drug survival favored rituximab/ocrelizumab or alemtuzumab over fingolimod (p < 0.001).
UNASSIGNED: Our study shows superior effectiveness of rituximab/ocrelizumab and alemtuzumab compared with fingolimod in stable patients switching from NTZ due to JC virus antibody positivity.
