We report a new sensitive label-free electrochemical immunosensor to detect Vitamin D3 (25-OHD3) in untreated serum samples. To this aim, a graphite screen printed electrode (SPE) was modified using cysteamine (CYM) functionalized core-shell magnetic nanoparticles (Au@MNPs) then, the 25-OHD3 antibody (AbD) was immobilized via glutaraldehyde crosslinking. The several steps involved in the immunosensor development and 25-OHD3 analysis were monitored by using differential pulse voltammetry (DPV). The developed immunosensor showed a LOD of 2.4 ng mL-1 and a linear range between 7.4 and 70 ng mL-1. The effectiveness of the immunosensor in human serum analysis was assessed by comparing the results obtained with the chemiluminescence-immunoassay (CLIA) reference method. The high sensitivity and excellent agreement with the reference method suggest its potential use as a POCT to monitor hypovitaminosis 25-OHD levels.
To explore neurological factors affecting quality of life (QoL) in children and young people with ataxia-telangiectasia (A-T), from both child and parent perspective.

24 children/young people with A-T (mean age 11.2±3.5 years; 13 males) and 20 parents were recruited, and 58% were reassessed after an average interval of 3.4 years. Participants completed the PedsQL QoL assessment. Participants with A-T underwent structured neurological examination. QoL data from 20 healthy controls and their parents was used for comparison.

Children/young people with A-T rated their QoL higher than parental ratings across time points, with no longitudinal change. Higher age of the child participant correlated with lower parental (r=-0.43, p=.008) but not child ratings of QoL (r=-0.16, p=.380). Child and parent QoL ratings from the A-T group were lower than respective ratings from controls (η

=0.44 and η

=0.75 respectively, both p<.0005, controlled for socioeconomic status). Parental, but not child, ratings of QoL was predicted by a regression model based on neurological scores (R
=0.44, p=<.001).

Neurological disability does not determine child/young person QoL ratings in A-T. While certain aspects of neurological disability predict parent-proxy ratings, there is no decline in QoL over time. These results may reflect resilience in the face of a complex life-limiting disorder.

The aim of the study was to assess the coagulation and inflammatory markers connected with severe course of COVID-19 and no clinical improvement.

The study population included 2590 adult patients, diagnosed with COVID-19, selected from the SARSTer national database - an ongoing project led by the Polish Association of Epidemiologists and Infectiologists and supported by the Medical Research Agency. Clinical and laboratory parameters, such as C-reactive protein (CRP), white blood cells (WBCs), neutrophil and lymphocyte count, procalcitonin, ferritin, interleukin-6 (IL-6), D-dimer concentration and platelet (PLT) count were analyzed before and after treatment (remdesivir, tocilizumab, dexamethasone, anticoagulants).

Significant differences between patients with mild and severe course of the disease were observed in all examined parameters before treatment (p<0.05). After treatment only ferritin concentration did not differ significantly. In patients with pulmonary embolism, CRP concentration, neutrophil count, D-dimer and IL-6 concentration were significantly higher than in patients without embolism (p<0.05). The significant differences between the groups with and without fatal outcome were observed within all analyzed parameters. Significant differences in all examined parameters before treatment were observed between patients with and without clinical improvement (p<0.05). Multivariate logistic regression showed that no clinical improvement was associated with IL-6>100pg/ml (OR-2.14), D-dimer concentration over 1000ng/ml (OR-1.62) and PLT count below 150,000/μl (OR-1.57).

Severe course of the disease is associated with lower PLT and lymphocyte count, higher D-dimer, CRP, neutrophil count and IL-6 concentration. The best predictors of no clinical improvement in COVID-19 are IL-6>100pg/ml, D-dimer>1000ng/ml and PLT<150,000/μl.
1000 ng/ml and PLT less then 150,000/μl."Thermal expansion and cold contraction" are common occurrences in nature. KP-457 ic50 Resulting from "thermal expansion and cold contraction" reaction, strain effect is created, which affects the oxygen reduction reaction (ORR) activities of fuel cell catalysts. Nevertheless, the "thermal expansion and cold contraction" effects of catalysts have rarely been investigated. Herein, the influence of "thermal expansion and cold contraction" strains upon ORR activities of NiO/CoO catalysts is investigated. Experimental and first-principles calculations reveal that, when NiO/CoO are synthesized and used as catalysts under low temperature ice/water environment, there is virtually no strain effect created, and abundant active sites contribute to the good low temperature ORR activities of NiO/CoO catalysts (onset potential 0.736 V, halfwave potential 0.659 V). When high temperature synthesized NiO/CoO catalysts are used at low temperature, however, small amounts of active sites are created. Moreover, the adsorption activity of NiO(222) and CoO(311) stepped active sites are weakened by compressive strain of lattice contraction, which reduces their ORR activities. The "low temperature synthesis and low temperature catalysis" route proposed by this paper paves a new road for the synthesis and design of low-temperature catalysts.We present a case for developing a millikelvin-temperature transmission electron microscope (TEM). We start by reviewing known reasons for such development, then present new possibilities that have been opened up by recent progress in superconducting quantum circuitry, and finally report on our ongoing experimental effort. Specifically, we first review possibilities to observe a quantum mechanically superposed electromagnetic field around a superconducting qubit. This is followed by a new idea on TEM observation of microwave photons in an unusual quantum state in a resonator. We then proceed to review potential applications of these phenomena, which include low dose electron microscopy beyond the standard quantum limit. Finally, anticipated engineering challenges, as well as the authors' current ongoing experimental effort towards building a millikelvin TEM are described. In addition, we provide a brief introduction to superconducting circuitry in the Appendix for the interested reader who is not familiar with the subject.The Publisher regrets that this article is an accidental duplication of an article that has already been published in Micron, Volume 161, October 2022, 103325, https//doi.org/10.1016/j.micron.2022.103325.

Diffuse-type tenosynovial giant cell tumour (D-TGCT) is a non-malignant but locally aggressive tumour driven by overexpression of colony-stimulating factor-1 (CSF1). CSF1R inhibitors are potential therapeutic strategies for patients not amenable to surgery. We report here the long-term outcome of nilotinib in patients with advanced D-TGCT treated within a phase II prospective international study (ClinicalTrials.gov NCT01261429).

Patients were enrolled between December 2010-September 2012at 11 cancer centres. Eligible patients had histologically confirmed D-TGCT, not amenable to surgery. Patients received nilotinib until evidence of progression, toxicityor a maximum of one year. Long-term data were retrospectively collected after the completion of the phase II trial. Patients with nilotinib treatment ≥12 weeks and follow-up ≥12 months were included for long-term analysis.

Forty-eight of 56 enrolled patients were included. Median treatment duration was 11 months; 31 (65%) patients completed the treatment ow-up. Contrarily, several patients had ongoing disease control after limited treatment duration, demonstrating the mixed effect of nilotinib.
Anaplastic thyroid cancer (ATC) is a rare and highly aggressive cancer for which effective systemic therapy has long been sought. Here, we assessed the efficacy and safety of lenvatinib in patients with unresectable ATC.

The study was investigator-initiated and conducted under a multicenter, open-label, nonrandomized, phase II design. Eligibility criteria included pathologically proven ATC; unresectable measurable lesion as defined by RECIST 1.1; age 20 years or older; ECOG PS 0-2; and adequate organ function. The primary end-point was overall survival. Secondary end-points were progression-free survival, objective response rate, disease control rate, clinical benefit rate, and safety.

Of 52 patients enrolled from 17 institutions, 42 patients who were confirmed to have ATC were included for efficacy analysis, and 50 patients were included for safety analysis. The estimated 1-year overall survival rate was 11.9% (95% CI, 4.4%-23.6%). One patient (2.4%) achieved complete response, four patients (9.5%) parnvestigation to identify suitable candidates for lenvatinib monotherapy is needed.
To provide practice guidelines about fertility preservation (FP) in oncology.

We selected 400 articles after a PubMed review of the literature (1987-2019).

Any child, adolescent and adult of reproductive age should be informed about the risk of treatment gonadotoxicity. In women, systematically proposed FP counselling between 15 and 38 years of age in case of treatment including bifunctional alkylating agents, above 6g/m2 cyclophosphamide equivalent dose (CED), and for radiation doses on the ovaries ≥3Gy. For postmenarchal patients, oocyte cryopreservation after ovarian stimulation is the first-line FP technique. Ovarian tissue cryopreservation should be discussed as a first-line approach in case of treatment with a high gonadotoxic risk, when chemotherapy has already started and in urgent cases. Ovarian transposition is to be discussed prior to pelvic radiotherapy involving a high risk of premature ovarian failure. For prepubertal girls, ovarian tissue cryopreservation should be proposed in the case ofemotherapy with a CED ≥5.000 mg/m2 or radiotherapy ≥2 Gy. If several possible strategies, the ultimate choice is made by the patient.
Elderly patients with advanced pancreatic adenocarcinoma (APC) are conceived to be frailer and susceptible to treatment toxicity that has led to disparity in lower likelihood of receiving chemotherapy and survival. Optimal chemotherapy is an unmet medical need for elderly patients with APC.

Patients with chemo-naive APC, age ≥70 years, and Eastern Cooperative Oncology Group (ECOG) performance score ≤2 were eligible. The treatment was consisted of biweekly gemcitabine 800mg/m
, 10mg/m
/min infusion on day 1 plus oral S-1 and leucovorin (40-60 and 30mg, respectively) twice daily on days 1-7, the GSL regimen. The primary end-point was progression-free survival with an interested P
of 5.0 months.

Of the 49 enrolled patients, the median age was 76 years, ECOG performance score ≥1 in 59.2%, metastatic diseases in 65.3%, Vulnerable Elders Survey-13 score ≥3 in 71.4%, and Geriatric 8 score ≤14 in 93.9%. After a median 11 cycles of treatment, the overall response rate and disease control rate were 26.5% and 75.
