Patients' Ability to Take Dermoscopic Follow-Up Images of Atypical Melanocytic Lesions With Smartphones: A Pilot Study.

Introduction: Short-term teledermoscopic monitoring helps to distinguish early melanomas from nevi. As the incidence of melanoma is increasing, there are several benefits of patients' taking their own dermoscopic images, but only a few previous studies have investigated the feasibility of this approach.

Objectives: To examine patients' ability to take evaluable dermoscopic images of atypical melanocytic lesions in need of short-term monitoring.

Illness Stigma and Shame in People With Chronic Illnesses vs. SARS-CoV-2 Survivors: Associations With Psychological Distress Through Psychological Flexibility and Self-Compassion.

Individuals with chronic illnesses and those infected with SARS-CoV-2 often face stigma, shame, and psychological distress related to their conditions. Higher psychological flexibility and self-compassion are often associated with less stigma and shame. Examining and comparing these experiences between people with chronic illness and people who have recovered from SARS-CoV-2 can provide valuable insights into the shared and unique challenges they encounter.

Vaccine response was higher in formula-fed infants compared to breastfed but not affected by lactoferrin or iron in a randomised controlled trial.

Aim: To examine how reduced iron content and added bovine lactoferrin in infant formula affect the antibody response following routine immunisation.

Methods: In this randomised controlled trial, 180 Swedish formula-fed infants received, from 6 weeks to 6 months of age, a 2 mg/L iron formula with (n = 72) or without (n = 72) bovine lactoferrin, or a control formula with 8 mg/L iron and no lactoferrin (n = 36). Another 72 infants were recruited as a breastfed reference.

Hydrogen production by a fully enzyme.

Molecular catalysts based on abundant elements that function in neutral water represent an essential component of sustainable hydrogen production. Artificial hydrogenases based on protein-inorganic hybrids have emerged as an intriguing class of catalysts for this purpose. We have prepared a novel artificial hydrogenase based on cobaloxime bound to a three alpha-helical protein, αC, a pyridyl-based unnatural amino acid.

Validation of red flags in the workup of children with long-term abdominal pain - A retrospective study.

Aim: To evaluate red flags as an instrument to distinguish other medical conditions from Functional Gastrointestinal Disorders (FGID) in children with long-term abdominal pain.

Methods: In a retrospective follow-up, data were collected from 317 children who were referred for medical assessment due to long-term abdominal pain between the years 2011 and 2012 at three Swedish paediatric open clinic units in Sweden. Throughout the review of medical records, any documented red flags at the primary consultation and finally set diagnosis after 1 year were noted for all cases.

Discovery of the Potent and Selective Inhaled Janus Kinase 1 Inhibitor AZD4604 and Its Preclinical Characterization.

JAK-STAT cytokines are critical in regulating immunity. Persistent activation of JAK-STAT signaling pathways by cytokines drives chronic inflammatory diseases such as asthma. Herein, we report on the discovery of a highly JAK1-selective, ATP-competitive series of inhibitors having a 1000-fold selectivity over other JAK family members and the approach used to identify compounds suitable for inhaled administration.

Normal range and predictors of serum erythroferrone in infants.

Background: Erythroferrone (ERFE) has been identified as a hepcidin-regulating hormone synthetized by erythroblasts correlating to the erythropoietic activity and the needs for iron substrate in bone marrow of adults. The present study aimed to assess the ERFE serum concentrations and its predictors in infants.

Methods: ERFE was explored at 4 time points during the first year of life in 45 healthy, breastfed, normal birth weight (NBW) infants, and 136 marginally low birth weight infants (LBW, 2000-2500 g) receiving iron (N = 58) or placebo (N = 78) between 6 weeks and 6 months of age.

Characterization of Selective and Potent JAK1 Inhibitors Intended for the Inhaled Treatment of Asthma.

Purpose: Janus kinase 1 (JAK1) is implicated in multiple inflammatory pathways that are critical for the pathogenesis of asthma, including the interleukin (IL)-4, IL-5, IL-13, and thymic stromal lymphopoietin cytokine signaling pathways, which have previously been targeted to treat allergic asthma. Here, we describe the development of AZD0449 and AZD4604, two novel and highly selective JAK1 inhibitors with promising properties for inhalation.

Methods: The effects of AZD0449 and AZD4604 in JAK1 signaling pathways were assessed by measuring phosphorylation of signal transducer and activator of transcription (STAT) proteins and chemokine release using immunoassays of whole blood from healthy human volunteers and rats.

Curettage vs. cryosurgery for superficial basal cell carcinoma: a prospective, randomised and controlled trial.

Background: Basal cell carcinoma (BCC) is the most common cancer in the world and has a rising incidence. Current guidelines for low-risk BCC including superficial BCC (sBCC) recommend several treatment options including destructive treatment methods, such as cryosurgery with or without prior curettage or curettage and electrodesiccation. Curettage only (i.

The downward spiralling nature of the North Atlantic Subtropical Gyre.

The Atlantic Meridional Overturning Circulation (AMOC) regulates the heat distribution and climate of Earth. Here we identify a new feature of the circulation within the North Atlantic Subtropical Gyre that is associated with the northward flowing component of the AMOC. We find that 70% of the water that flows northwards as part of the AMOC circulates the Gyre at least once before it can continue northwards.

Cardiorenal function and survival in in-hospital cardiac arrest: A nationwide study of 22,819 cases.

Background: We studied the association between cardiorenal function and survival, neurological outcome and trends in survival after in-hospital cardiac arrest (IHCA).

Methods: We included cases aged ≥ 18 years in the Swedish Cardiopulmonary Resuscitation Registry during 2008 to 2020. The CKD-EPI equation was used to calculate estimated glomerular filtration rate (eGFR).

Immunological Effects of Adding Bovine Lactoferrin and Reducing Iron in Infant Formula: A Randomized Controlled Trial.

Objectives: Compared to formula-fed infants, breastfed infants have a lower risk of infections. Two possible reasons for this are the presence of the anti-infective and anti-inflammatory protein lactoferrin and the lower level of iron in breast milk. We explored how adding bovine lactoferrin and reducing the iron concentration in infant formula affect immunology and risk of infections in healthy infants.

Revealing the relationship between photoelectrochemical performance and interface hole trapping in CuBiO heterojunction photoelectrodes.

p-Type CuBiO is considered a promising metal oxide semiconductor for large-scale, economic solar water splitting due to the optimal band structure and low-cost fabrication. The main challenge in utilizing CuBiO as a photoelectrode for water splitting, is that it must be protected from photo-corrosion in aqueous solutions, an inherent problem for Cu-based metal oxide photoelectrodes. In this work, several buffer layers (CdS, BiVO, and GaO) were tested between CuBiO and conformal TiO as the protection layer.

Incomplete Excisions of Melanocytic Lesions: Rates and Risk Factors.

Incomplete excisions of melanocytic lesions occur despite the intention of complete removal. The aim of this study was to determine the incomplete excision rates for benign and malignant melanocytic lesions and the associated risk factors. Demographic, clinical, and histo-pathological data possibly associated with incomplete excision were collected from 2,782 consecutive excisions between 2014 and 2015.

Iron deficiency in infancy: current insights.

Purpose Of Review: Iron deficiency is the most common micronutrient deficiency and infants are at particular risk. The purpose of this review is to summarize recent studies that explored the metabolism of iron in infants as well as the risks and benefits of iron supplementation in different populations.

Recent Findings: The ability of infants to regulate iron homeostasis is not fully known but most likely different from adults.

Reducing Iron Content in Infant Formula from 8 to 2 mg/L Does Not Increase the Risk of Iron Deficiency at 4 or 6 Months of Age: A Randomized Controlled Trial.

Many infant formulas are fortified with iron at 8-14 mg/L whereas breast milk contains about 0.3 mg/L. Another major difference between breast milk and infant formula is its high concentration of lactoferrin, a bioactive iron-binding protein.

Hepcidin is a relevant iron status indicator in infancy: results from a randomized trial of early vs. delayed cord clamping.

Background: We aimed to evaluate whether serum hepcidin is a useful indicator of iron status in infants.

Methods: Term infants (n = 400) were randomized to delayed (≥180 s) or early (≤10 s) cord clamping (CC). Iron status was assessed at 4 and 12 months.

Assessment of a W:BiVO-CuBiOTandem Photoelectrochemical Cell for Overall Solar Water Splitting.

We assess a tandem photoelectrochemical cell consisting of a W:BiVO photoanode top absorber and a CuBiO photocathode bottom absorber for overall solar water splitting. We show that the W:BiVO photoanode oxidizes water and produces oxygen at potentials ≥0.7 V vs RHE when CoPi is added as a cocatalyst.

Diagnostic accuracy and safety of short-term teledermoscopic monitoring of atypical melanocytic lesions.

Background: Short-term dermoscopic monitoring (STDM) of atypical melanocytic lesions (AML) after 3.0-4.5 months can be used to detect featureless melanomas without performing countless unnecessary excisions of nevi.

A carbon mass-balance budget for a periglacial catchment in West Greenland - Linking the terrestrial and aquatic systems.

Climate change is predicted to have far reaching consequences for the mobility of carbon in arctic landscapes. On a regional scale, carbon cycling is highly dependent on interactions between terrestrial and aquatic parts of a catchment. Despite this, studies that integrate the terrestrial and aquatic systems and study entire catchments using site-specific data are rare.

Class Id ribonucleotide reductase utilizes a Mn(IV,III) cofactor and undergoes large conformational changes on metal loading.

Outside of the photosynthetic machinery, high-valent manganese cofactors are rare in biology. It was proposed that a recently discovered subclass of ribonucleotide reductase (RNR), class Id, is dependent on a Mn(IV,III) cofactor for catalysis. Class I RNRs consist of a substrate-binding component (NrdA) and a metal-containing radical-generating component (NrdB).
