Laser ablation multi‐collector mass spectrometry (LA‐MC‐ICP‐MS) has emerged as the technique of choice for in situ measurements of Sr isotopes in geological minerals. However, the method poses analytical challenges and there is no widely adopted standardised approach to collecting these data or correcting the numerous potential isobaric inferences. Here, we outline practical analytical procedures and data reduction strategies to help establish a consistent framework for collecting and correcting Sr isotope measurements in geological materials by LA‐MC‐ICP‐MS. We characterise a new set of plagioclase reference materials, which are available for distribution to the community, and present a new data reduction scheme for the Iolite software package to correct isobaric interferences for different materials and analytical conditions. Our tests show that a combination of Kr‐baseline subtraction, Rb‐peak‐stripping using βRb derived from a bracketing glass reference material, and a CaCa or CaAr correction for plagioclase and CaCa or CaAr + REE2+ correction for rock glasses, yields the most accurate and precise 87Sr/86Sr measurements for these materials. Using the analytical and correction procedures outlined herein, spot analyses using a beam diameter of 100 μm or rastering with a 50–65 μm diameter beam can readily achieve < 100 ppm 2SE repeatability ("internal") precision for 87Sr/86Sr measurements for materials with < 1000 μg g‐1 Sr.

AbstractBackgroundCluster headache is commonly reported to follow an annual pattern with a peak in the spring and a second peak in autumn. Patients with headache frequently use search engines, such as Google, to look for terms related to their disease, creating trend data that can be analyzed with Google Trends. Indeed, Google Trends has been used for surveillance studies and can provide indirect estimates of the burden of diseases and symptoms. The present cross‐sectional study investigated the seasonality of searches for “cluster headache” in the northern and southern hemispheres using 10 years of Google Trends data.MethodsThe term “cluster headache” or its translation in the 10 most spoken languages in the world was searched on Google Trends to obtain relative search volumes (from 0 to 100), in order to compare variations in searches across periods. Twenty‐eight countries were selected according to the following criteria: (1) a relative search volume of >40 for the term for cluster headache; and (2) a population of at least 5 million inhabitants. For statistical purposes, countries were grouped in relation to hemisphere (northern or southern). Relative search volumes were extracted from January 2012 to January 2022 and analyzed according to two subgroups based on meteorological seasons (summer and winter vs. spring and autumn).ResultsA seasonal trend for in searches for cluster headache was found worldwide exhibiting higher relative search volumes in spring and autumn compared with summer and winter (17 [0, 39] vs. 13 [0, 37]; p = 0.016).ConclusionHigher search volumes for the term during the meteorological seasons of spring and autumn clearly reflect a circannual pattern of cluster headache occurrence, representing new evidence for its seasonality.

AbstractVisual snow is the main symptom of visual snow syndrome, a disorder of predominantly visual disturbances initially described in patients without abnormalities on ancillary investigations. We present a case series of patients with visual snow in the setting of acute ischemic stroke. The first and second patient reported previous episodic visual snow with migraine attacks. The third patient experienced visual snow for the first time during the ischemic stroke. In the first patient, the ischemic stroke affected the right and left precuneus and the right lingual gyrus. In the second patient, the ischemic stroke was located in the left lingual gyrus, parts of the left fusiform and parahippocampal gyrus, left dorso‐lateral thalamus, and left cerebellar hemisphere. In the third patient, occipital pole, trunk of the corpus callosum on the right, right paramedian pons, right cerebellar hemisphere, and vermis were affected. Our case series indicates that the symptom visual snow can be caused by vascular lesions in areas of visual processing. Because patients did not meet criteria for visual snow syndrome, dysfunction in the affected areas might only explain part of the complex pathophysiology of visual snow syndrome.

AbstractBackgroundThe treatment of Helicobacter pylori (H. pylori) infection is a challenge for those who cannot use amoxicillin.ObjectiveTo evaluate the eradication rate and adverse effects of vonoprazan and tetracycline dual therapy as first‐line and rescue treatment regimens used in special populations with penicillin allergy or failed in previous amoxicillin‐containing therapies.DesignPatients enrolled were those who were H. pylori‐positive with selected conditions: (1) allergic to penicillin, either naïve to treatment or had failed before; or (2) failed in previous amoxicillin‐containing therapies. All enrolled patients accepted 14‐day vonoprazan and tetracycline dual therapy (VT dual therapy) as follows: vonoprazan (20 mg b.i.d.) and tetracycline (500 mg t.i.d. [body weight < 70 kg] or 500 mg q.i.d. [body weight ≥ 70 kg]). H. pylori status was evaluated by 13C‐urease breath test 6 weeks after treatment. All adverse effects were recorded. Some patients underwent bacterial culture and antibiotic susceptibility testing.ResultsA total of 62 patients were enrolled; 18 of them received VT dual therapy as first‐line treatment, 44 patients received VT dual therapy as rescue treatment. Overall, 58 of 62 patients achieved successful eradication (93.5%), while all involved (100%,18/18) succeeded in the first‐line treatment group and 40 cases (90.9%, 40/44) succeeded in the rescue treatment group. Sixty‐one (61/62, 98.4%) patients completed the whole course of treatment. Adverse events occurred in 6 patients (6/62, 9.7%), while one patient quit because of skin rash. All adverse effects were mild and relieved spontaneously after H. pylori treatment. Five patients achieved successful H. pylori culture, and all strains isolated were sensitive to tetracycline.ConclusionsFor the treatment of H. pylori infection in special populations with penicillin allergy or failed in previous amoxicillin‐containing therapies, a 14‐day vonoprazan and tetracycline dual therapy was effective and safe as first‐line and rescue treatment in our study. Further study is warranted to verify its efficacy, especially for those who cannot use amoxicillin.

AbstractTo investigate the influencing factors of lower limb amputation in patients with diabetic foot ulcers. Patients with diabetic foot ulcers who were hospitalised in a tertiary general hospital in Guizhou Province from January 2019 to March 2022 were retrospectively collected. Sociological information of the general population, comorbidities, laboratory‐related indicators, and information on the specialty situation, using univariate analysis and multifactor analysis, compared the influencing factors of amputation and non‐amputee patients. A total of 205 patients with diabetic foot and 69 ampute patients (33.7%) were enrolled. The univariate analysis found that the decrease in HDL cholesterol levels was associated with the occurrence of lower extremity amputation, and logistic stepwise regression analysis showed that HDL‐C was inversely correlated with the amputation rate of patients with diabetic foot ulcers, and the risk of amputation at low levels of HDL‐C was 2.452 times higher than that of high‐level HDL‐C (95% CI: 1.105–5.846). Decreased HDL cholesterol levels are an independent predictor of amputation in patients with diabetic foot ulcers.

AbstractBecause of an increased risk of local recurrence following surgical treatment of lentigo maligna (melanoma) (LM/LMM), the optimal surgical technique is still a matter of debate. We aimed to evaluate the effect of different surgical techniques and reflectance confocal microscopy (RCM) on local recurrence and survival outcomes. We searched MEDLINE, Embase and PubMed databases through 20 May 2022. Randomized and observational studies with ≥10 lesions were eligible for inclusion. Bias assessment was performed using the Methodological Index for Non‐Randomized Studies instrument. Meta‐analysis was performed for local recurrence, as there were insufficient events for the other clinical outcomes. We included 41 studies with 5059 LM and 1271 LMM. Surgical techniques included wide local excision (WLE) (n = 1355), staged excision (n = 2442) and Mohs' micrographic surgery (MMS) (n = 2909). Six studies included RCM. The guideline‐recommended margin was insufficient in 21.6%–44.6% of LM/LMM. Local recurrence rate was lowest for patients treated by MMS combined with immunohistochemistry (<1%; 95% CI, 0.3%–1.9%), and highest for WLE (13%; 95% CI, 7.2%–21.6%). The mean follow‐up varied from 27 to 63 months depending on surgical technique with moderate to high heterogeneity for MMS and WLE. Handheld‐RCM decreased both the rate of positive histological margins (p < 0.0001) and necessary surgical stages (p < 0.0001). The majority of regional (17/25) and distant (34/43) recurrences occurred in patients treated by WLE. Melanoma‐associated mortality was low (1.5%; 32/2107), and more patients died due to unrelated causes (6.7%; 107/1608). This systematic review shows a clear reduction in local recurrences using microscopically controlled surgical techniques over WLE. The use of HH‐RCM showed a trend in the reduction in incomplete resections and local recurrences even when used with WLE. Due to selection bias, heterogeneity, low prevalence of stage III/IV disease and limited survival data, it was not possible to determine the effect of the different surgical techniques on survival outcomes.
Otolith mineralogy affects otolith shape asymmetry: a comparison of hatchery and natural origin Coho salmon (Oncorhynchus kisutch)

Published: January 2023

AbstractMany aspects of natural and hatchery origin salmonid genetics, physiology, behaviour, anatomy and life histories have been compared due to the concerns about what effects domestication and hatchery rearing conditions have on fitness. Genetic and environmental stressors associated with hatchery rearing could cause greater developmental instability (DI), and therefore a higher degree of fluctuating asymmetry (FA) in various bilaterally paired characters, such as otoliths. Nonetheless, to appropriately infer the effects of DI on otolith asymmetry, otolith mineralogy must be accounted for. Vateritic otoliths differ substantially from aragonitic otoliths in terms of mass and shape and can artificially inflate any measurement of FA if not properly accounted for. In this study, measurements of otolith asymmetry between hatchery and natural origin Coho salmon Oncorhynchus kisutch from three different river systems were compared to assess the overall differences in asymmetry when the calcium carbonate polymorph accounted for 59.3% of otoliths from hatchery origin O. kisutch was vateritic compared to 11.7% of otoliths from natural origin O. kisutch. Otolith mineralogy, rather than origin, was the most significant factor influencing the differences in asymmetry for each shape metric. When only aragonitic otoliths were compared, there was no difference in absolute asymmetry between hatchery and natural origin O. kisutch. The authors recommend other researchers to assess otolith mineralogy when conducting studies regarding otolith morphometrics and otolith FA.

AbstractEuropean eel is critically endangered in Europe. Among other stressors, pathogens are well‐known to harm eels' fitness. One hundred and eighty‐two eels were captured in three Eel Management Units in Andalucía (SE Spain) and analysed for Anguillicoloides crassus, Anguillid herpesvirus 1 (AngHV1), the rhabdovirus Eel Virus European X (EVEX) and the aquabirnavirus Eel Virus European (EVE). A. crassus adults and preadults were isolated and morphometrically identified, and the eel swimbladders were artificially digested to count A. crassus larvae. Also, eel tissues were examined by PCRs for the presence of viruses. EVEX and EVE were not detected in any of the eels. The estimated prevalence (95% confidence limits) was 71 (64–78)% for A. crassus and 35 (28–42)% for AngHV‐1, varying these prevalences significantly between and within EMUs. Moreover, A. crassus prevalence was highest in smaller eels, in sites closest to the sea and eels sampled in the autumn. By contrast, AngHV‐1 prevalence was highest in biggest eels, in sites far from the sea and sampled in the summer or winter. However, in mixed effects logistic models including site as a random variable, the risk of infection was associated with distance to the sea in both A. crassus and AngHV‐1 infections and also to winter sampling in the case of AngHV‐1 and not to other variables. These results are evidence that both pathogens are highly endemic in eels from Andalusian habitats. Further studies are needed to better understand the risk factors associated with these pathogens on eel populations.
Biased Auctioneers

ABSTRACTWe construct a neural network algorithm that generates price predictions for art at auction, relying on both visual and nonvisual object characteristics. We find that higher automated valuations relative to auction house presale estimates are associated with substantially higher price‐to‐estimate ratios and lower buy‐in rates, pointing to estimates' informational inefficiency. The relative contribution of machine learning is higher for artists with less dispersed and lower average prices. Furthermore, we show that auctioneers' prediction errors are persistent both at the artist and at the auction house level, and hence directly predictable themselves using information on past errors.
Information Aggregation via Contracting
Authors: LI JIASUN 
Published: January 2023

ABSTRACTWhen a group of investors with dispersed private information jointly invest in a risky project, how should they divide the project's profit? We show that a simple contract dividing profits in proportion to investors' risk tolerances may facilitate information aggregation by altering investors' risk‐taking incentives when they decide on how investment strategies respond to private information. Our results provide a contracting‐based approach for information aggregation, which is an alternative to learning from endogenous market variables (e.g., prices) via contingent schedules as seen in well‐known rational expectations equilibrium models.

Published: January 2023

AbstractObjectivePersonality traits change in both mean levels and variance across the life span but the mechanisms underlying these developmental trends remain unclear. Social Investment Principle (SIP) suggests that social expectations drive personality changes in adulthood. Accordingly, we tested whether differences between personality traits in social expectations for them can explain their different change trajectories in young adulthood.MethodsA pool of 257 personality items was used to measure personality traits' means and variances (N = 1096), and levels expected by friends, partners and bosses/supervisors (N = 121).ResultsRaters were consistent in their expectations for how young adults should think, feel and behave. Traits under stronger expectations had higher mean levels and lower variances than traits under lower expectations; trait means and variances increased with age, but inconsistently with the SIP, these increases were unrelated to the traits' expected levels.ConclusionOur results are only partially consistent with the SIP.

AbstractObjectiveAlthough intelligence and personality traits have long been recognized as key predictors of students' academic achievement, little is known about their longitudinal and reciprocal associations. Here, we charted the developmental interplay of intelligence, personality (Big Five) and academic achievement in 3880 German secondary school students, who were assessed four times between the ages 11 and 14 years (i.e., in grades 5, 6, 7, and 8).MethodWe fitted random intercept cross‐lagged panel models (RI‐CLPs) to investigate reciprocal within‐person associations between (a) academic achievement and intelligence, (b) academic achievement and personality, as well as (c) intelligence and personality.ResultsThe results revealed negative within‐person associations between Conscientiousness and Extraversion assessed at the first wave of measurement and intelligence assessed at the second wave. None of the reciprocal personality–achievement associations attained statistical significance. Academic achievement and intelligence showed reciprocal within‐person relations, with the strongest coefficients found for achievement longitudinally predicting intelligence.ConclusionsOur work contributes to developmental theorizing on interrelations between personality, intelligence, and academic achievement, as well as to within‐person conceptualizations in personality research.

AbstractThe average incidence of AMV infection in sugar beet was 20% as detected by RT‐PCR in selected governorates of Egypt (El‐Beheira, Kafr El‐Shaykh and Alexandria). Nucleotide sequencing of the complete genome of AMV EGY1 isolated from sugar beet plants was determined. Analysis of comparable sequences showed that total nucleotide sequence similarity between the AMV Beet‐EGY1 isolate and the FER isolate (Solanum tuberosum) from Egypt is 97.86%, 98.01% and 97.79% for RNAs 1, 2 and 3 respectively. Phylogenetic analysis indicated that AMV EGY1 isolate occupied a separate clade with FER isolate from Egypt; it suggests that the isolate from Beta vulgaris is different from other previously reported isolates. Nucleotide and amino acid sequence comparison of all isolates revealed that the Egyptian isolates appear to be more linked to subgroup II when compared to subgroup I and belong to subgroup IIC. This is the first report of a full genome sequence of AMV infecting sugar beet.
Receiving thank you letters in inpatient child and adolescent mental health services (CAMHS): A qualitative study of nurse's experiences

Published: January 2023

AbstractIntroductionPrevious research has found that nurses in inpatient CAMHS can struggle to define their role and contribution to patient care. While gratitude has received increased attention in relation to subjective well‐being in healthcare settings, the receipt of gratitude in the form of thank you letters is currently unexplored in the CAMHS context.Aim/QuestionTo gain an understanding of how inpatient CAMHS nursing staff experience receiving expressions of gratitude from patients.MethodAdopting an exploratory qualitative approach, two focus group interviews were conducted. Participants completed a brief online follow‐up questionnaire. Data were examined using thematic analysis.ResultsReflecting on expressions of gratitude improved understanding of professional identity, enhanced reflexivity, enhanced team cohesion and increased professional and personal confidence and motivation.DiscussionExpressions of gratitude appear to offer meaningful sources of feedback for nurses and support a greater sense of personal accomplishment, professional role and the relational impact of care for patients. When nurses share and discuss expressions of gratitude with colleagues this brings benefits additional to the initial receipt.Implications for Mental Health NursingNurses should be supported to engage in discussing and reflecting upon receiving thank you letters and other tokens of gratitude although care should be taken to support those who might experience unease or increased self‐doubt.
