Impact of adjuvant trastuzumab therapy and its discontinuation on cardiac function and mortality in patients with early-stage breast cancer: An analysis based on the Japanese Receipt Claim Database.

Standard trastuzumab therapy can reduce the risk of early recurrence of HER2-positive breast cancer. However, trastuzumab-induced cardiac dysfunction may force the discontinuation of adjuvant trastuzumab therapy. Incidentally, there are still unclear whether or not trastuzumab treatment should be continued in the setting of reduced cardiac function.

Internet of things-based approach for glycemic control in people with type 2 diabetes: A randomized controlled trial.

Aims: The utilization of long-term effect of internet of things (IoT) on glycemic control is controversial. This trial aimed to examine the effect of an IoT-based approach for type 2 diabetes.

Materials And Methods: This randomized controlled trial enrolled 1,159 adults aged 20-74 years with type 2 diabetes with a HbA1c of 6.

Synthesis and Photophysical Properties of Silver(I) Coordination Polymers Bridged by Dimethylpyrazine: Comparison of Emissive Excited States between Silver(I) and Copper(I) Congeners.

Highly luminescent silver(I) coordination polymers [AgX(PPh)(Mepyz)] (X = I, Br, Cl; Mepyz: 2,5-dimethylpyrazine) were prepared together with copper congeners [CuX(PPh)(Mepyz)] (X = I, Br). All the complexes showed thermally activated delayed fluorescence from the charge-transfer states in the visible region, from blue to red. The isomorphous relationship among the complexes allowed a detailed discussion of the effect of halogenido ligands and crystal packing on their luminescence energy.

Neuropathic pain development and maintenance and its association with motor recovery after cervical spinal cord injury.

Background: In our published randomized controlled trial, we revealed that patients with acute ASIA Grade C incomplete cervical spinal cord injury (SCI) who underwent early surgery (within 24 h post-injury) had accelerated motor recovery at six months than those with delayed surgery (>2 weeks post-injury); however, neuropathic pain (NeP) worsened regardless of surgery timing. Here, we conducted analyses to intensively assess NeP development and maintenance.

Methods: Of 44 patients (median 64.

A powered simple walking model explains the decline in propulsive force and hip flexion torque compensation in human gait.

Excessive hip flexion torque to prioritize leg swings in the elderly is likely to be a factor that reduces their propulsive force and gait stability, but the mechanism is not clear. To understand the mechanism, we investigated how propulsive force, hip flexion torque, and margin of stability (MoS) change when only the hip spring stiffness is increased without changing the walking speed in the simple walking model, and verified whether the relationship holds in human walking. The results showed that at walking speeds between 0.

Chronic heat stress induces renal fibrosis and mitochondrial dysfunction in laying hens.

Background: Heat stress in laying hens negatively affects egg production and shell quality by disrupting the homeostasis of plasma calcium and phosphorus levels. Although the kidney plays an important role in calcium and phosphorus homeostasis, evidence regarding the effect of heat stress on renal injury in laying hens is yet to be elucidated. Therefore, the aim of this study was to evaluate the effects of chronic heat stress on renal damage in hens during laying periods.

1D Supramolecular Assemblies That Crystallize and Form Gels in Response to the Shape-Complementarity of Alcohols.

-9-Fluorenylmethyloxycarbonyl (Fmoc)- and -tertiary butyl (-Bu)-protected glutamate (L-), bearing a phenanthroline moiety at the side residue, forms 1D supramolecular assemblies via H-bonding as well as undergoing π-stacking interactions to afford crystals or gels that depend on the shape-complementarity of coexisting alcohols, as demonstrated by structural analyses on these assemblies by means of single-crystal X-ray diffractometry and supplemented with small- and wide-angle X-ray scattering data. Moreover, the rheological measurements on the gels help to define a model for when gels and crystals are expected and found. These observations and conclusions highlight an important, but not very appreciated, aspect of solute-solvent interactions within supramolecular assemblies that can allow the constituent-aggregating molecules in some systems to exhibit high selectivity toward the structures of their solvents.

Postoperative Adjuvant Anastrozole for 10 or 5 Years in Patients With Hormone Receptor-Positive Breast Cancer: AERAS, a Randomized Multicenter Open-Label Phase III Trial.

Purpose: Treatment with an aromatase inhibitor for 5 years is the standard treatment for postmenopausal hormone receptor-positive breast cancer. We investigated the effects of extending this treatment to 10 years on disease-free survival (DFS).

Patients And Methods: This prospective, randomized, multicenter open-label phase III study assessed the effect of extending anastrozole treatment for an additional 5 years in postmenopausal patients who were disease-free after treatment with either 5 years of anastrozole alone or 2-3 years of tamoxifen followed by 2-3 years of anastrozole.

A self-complementary macrocycle by a dual interaction system.

Self-complementary assembly is one of the most promising phenomena for the formation of discrete assemblies, e.g., proteins and capsids.

Chemical Vapor Deposition of Edge-on Oriented 2D Conductive Metal-Organic Framework Thin Films.

We demonstrated the synthesis of a conductive two-dimensional metal-organic framework (MOF) thin film by single-step all-vapor-phase chemical vapor deposition (CVD). The synthesized large-area thin film of Cu(CO) has an edge-on-orientation with high crystallinity. Cu(CO) thin film-based microdevices were fabricated by e-beam lithography and had an electrical conductivity of 92.

Physical oral care prevents ventilator-associated pneumonia in Vietnam: A prospective interventional study.

Background: Ventilator-associated pneumonia (VAP) has emerged as a critical issue in the intensive care unit (ICU) because of its high burden on patients and medical staff. Here, we examined the potential for reducing VAP incidence through physical oral care interventions without any medication.

Methods: This prospective interventional study compared VAP incidence during an 8-month baseline period (usual oral care) and a 9-month intervention period (physical oral care with sponge brush) among patients who received mechanical ventilation for >48 h in a tertiary care hospital in Vietnam from 2017 to 2019.

Hydrogen Bonding Propagated Phase Separation in Quasi-Epitaxial Single Crystals: A Pd-Br Molecular Insulator.

In condensed matter, phase separation is strongly related to ferroelasticity, ferroelectricity, ferromagnetism, electron correlation, and crystallography. These ferroics are important for nano-electronic devices such as non-volatile memory. However, the quantitative information regarding the lattice (atomic) structure at the border of phase separation is unclear in many cases.

Cardiotoxicity of adjuvant chemotherapy with trastuzumab: a Japanese claim-based data analysis.

Objective: Adjuvant chemotherapy with trastuzumab improves the postoperative life expectancy of women with early-stage breast cancer. Although trastuzumab is reportedly cardiotoxic, quantification based on real-world evidence is lacking. Therefore, in this study, we aimed to analyse trastuzumab cardiotoxicity using a nationwide claim-based database.
