A deoxyfluoroalkylation-aromatization strategy to access fluoroalkyl arenes.

Fluoroalkyl arenes (Ar-R) are valuable substructures present in several FDA-approved drugs, patents, agrochemicals, and materials, and complementary strategies that enable access to a broad spectrum of Ar-R compounds benefit these applied fields. Herein, we report a deoxyfluoroalkylation-aromatization strategy to convert cyclohexanones into broad-spectrum Ar-R containing compounds. Generally, the fluoroalkyl sources were activated to participate in a 1,2-addition reaction followed by aromatization in a sequence that contrasts more common preparations of these Ar-R compounds, such as (i) transition-metal catalyzed cross-coupling reactions of aryl electrophiles and nucleophiles, and (ii) radical fluoroalkylation reactions of C-H bonds of arenes.

Accuracy of noninvasive total haemoglobin measurement for detecting anaemia in infants: a cross-sectional study in a well-child care clinic, Khon Kaen, Thailand.

Agreement between methods to assess potassium intake in patients with chronic kidney disease.

Background & Aims: In the general population, 24-h urine potassium excretion is considered the reference standard for estimating potassium intake. However, its agreement with food records and spot urine collections in adults living with chronic kidney disease (CKD) is not well-established. Given the risk of hyperkalemia related to changes in renal potassium handling, understanding if this reference standard is appropriate for the CKD population is important.

Accuracy of Rhythm Diagnostic Systems' MultiSense in Detection of Arterial Oxygen Saturation and Respiratory Rate During Hypoxia in Humans: Effects of Skin Color and Device Localization.

The continuous monitoring of oxygen saturation (SpO) and respiratory rates (RRs) are major clinical issues in many cardio-respiratory diseases and have been of tremendous importance during the COVID-19 pandemic. The early detection of hypoxemia was crucial since it precedes significant complications, and SpO follow-up allowed early hospital discharge in patients needing oxygen therapy. Nevertheless, fingertip devices showed some practical limitations.

Assessing the Consumption of Ultra-Processed Foods in People with Diabetes: Is a Specific NOVA Questionnaire Always Necessary?

Background/objectives: Despite the accumulating evidence on the detrimental impact of UPFs on health, a common limit of the available studies concerns the instruments used to collect information about the consumption of processed foods. Recently, a specific NOVA-FFQ was proposed for the evaluation of ultra-processed food (UPF) consumption, but it does not allow the simultaneous assessment of energy and nutrient intake. We evaluate the concordance between the NOVA-FFQ and a common questionnaire (EPIC-FFQ) when assessing (1) the intake of foods with different degrees of processing and (2) the relationship between diet composition and cardiometabolic profile.

Identifying Strong Neoantigen MHC-I/II Binding Candidates for Targeted Immunotherapy with SINE.

The discovery of tumor-derived neoantigens which elicit an immune response through major histocompatibility complex (MHC-I/II) binding has led to significant advancements in immunotherapy. While many neoantigens have been discovered through the identification of non-synonymous mutations, the rate of these is low in some cancers, including head and neck squamous cell carcinoma. Therefore, the identification of neoantigens through additional means, such as aberrant splicing, is necessary.

Day-to-day variability in sleep and activity predict the onset of a hypomanic episode in patients with bipolar disorder.

Detecting transitions in bipolar disorder (BD) is essential for implementing early interventions. Our aim was to identify the earliest indicator(s) of the onset of a hypomanic episode in BD. We hypothesized that objective changes in sleep would be the earliest indicator of a new hypomanic or manic episode.

Do you know your PSMA-tracer? Variability in the biodistribution of different PSMA ligands and its potential impact on defining PSMA-positivity prior to PSMA-targeted therapy.

Background: In clinical practice, several radiopharmaceuticals are used for PSMA-PET imaging, each with distinct biodistribution patterns. This may impact treatment decisions and outcomes, as eligibility for PSMA-directed radioligand therapy is usually assessed by comparing tumoral uptake to normal liver uptake as a reference. In this study, we aimed to compare tracer uptake intraindividually in various reference regions including liver, parotid gland and spleen as well as the respective tumor-to-background ratios (TBR) of different F-labeled PSMA ligands to today's standard radiopharmaceutical Ga-PSMA-11 in a series of patients with biochemical recurrence of prostate cancer who underwent a dual PSMA-PET examination as part of an individualized diagnostic approach.
