Screening for Psychological Distress in Vietnamese Cancer Patients: An Evaluation of the Distress Thermometer.

Background: Psychological distress is prevalent in patients with cancer, negatively affecting their treatment and quality of life. Clinical guidelines recommended screening all cancer patients routinely for psychological problems using simple measures such as the Distress Thermometer (DT) and Problem List (PL). This study is the first research in Vietnam to identify the optimal DT cutoff point to screen distress and the relationship with PL items among cancer patients.

Intrinsic defect formation and the effect of transition metal doping on transport properties in a ductile thermoelectric material α-AgS: a first-principles study.

In this paper, the electronic structure and transport properties of a ductile thermoelectric material α-Ag2S are examined using first-principles calculations combined with the Boltzmann transport equation within a constant relaxation-time approximation. The use of the exchange-correlation functional SCAN + rVV10 successfully describes the geometric and electronic structure of α-Ag2S with a direct bandgap value of 0.99 eV, which is consistent with the previous experimental observations.

Application of St Gallen Categories in Predicting Survival for Patients With Breast Cancer in Vietnam.

Breast cancer is a heterogeneous disease with different tumor subtypes. Identifying risk categories will help make better treatment decisions. Hence, this study aimed to predict the survival outcomes of invasive breast cancer in Vietnam, using St Gallen 2007 classification.

Nitric oxide adsorption effects on metal phthalocyanines.

The adsorption of nitric oxide (NO) on various metal phthalocyanines (MPc, M = Mn, Fe, Co) has been studied using first-principles calculations based on density functional theory (DFT). In this study, we investigated the fully optimized geometries and electronic structure of MPc. We found that the electronic structures of metal atoms are essential in shaping the ground-state electronic structure near the Fermi level.
