Metal NP @ metal-organic frameworks (MOFs) are widely used in electrocatalysis. However, many of the MOFs are poorly conductive. Here, we loaded bismuth (Bi) into a Zr-based MOF of the UiO structure that is active for CO reduction to formate and found that a moderate conductivity of the nanosized MOFs is sufficient to support a reasonably high catalytic current density. This finding allows simpler catalyst design and quantitative rationalization of MOF electrocatalysis.

Intro: The article tests the hypothesis that we can draw practical knowledge from the experience of service providers operating in the past. The research questions were formulated: can the historical example of the organization of medical care in the Polish Children's Hospital named after Karol and Maria be used as a viable example today? Is it relevant for contemporary practitioners? And do we still use the knowledge of predecessors? The authors decided to use the interwar Hospital and an operating paediatric ward of the Child-Friendly Hospital for a comparative analysis.

Methods: The model of the European Regional Office of the World Health Organization for integrated delivery of health services was adopted as the analysis framework.

Introduction: The sense of smell is one of the most developed and important senses that forms the bond between the newborn and the mother and allows the newborn to reach the mother's breast. The sense of smell begins to form during intrauterine life, and the sense of smell can be a marking tool for a newborn baby, so that the baby can recognize both his mother and his immediate environment and develop his behaviour accordingly. This is necessary not only for feeding babies but also for them to feel safe and peaceful in their new environment.

Aims And Objectives: Approximately 50% of Americans report having low health insurance literacy, leading to uncertainty when choosing their insurance coverage to best meet their healthcare needs. Therefore, we aimed to evaluate the association between lack of prescription drug benefit knowledge and problems paying medical bills among Medicare beneficiaries.

Methods: We analysed the 2021 Medicare Current Beneficiary Survey Public Use File of 5586 Medicare beneficiaries aged ≥ 65 years.

Introduction: Rheumatoid arthritis (RA) is a progressive autoimmune inflammatory disease. According to the European League Against Rheumatism (EULAR), the stages of RA progression include pre-RA, preclinical RA, inflammatory arthralgia, arthralgia with positive antibodies, arthralgia suspected of progressing to RA, undifferentiated arthritis and finally established RA. According to the Community Oriented Program for Control of Rheumatic Diseases (COPCORD), the prevalence of RA in Mexico is 1.
