Atmospheric Environment and COVID-19 Pandemic
Since the COVID-19 outbreak, the scientific community has been trying to clarify various problems, such as the mechanism of virus transmission, environmental impact, and socio-economic impact. The spread of COVID-19 in the atmospheric environment is variable and uncertain, potentially resulting in differences in air pollution. Many scholars are striving to explore the relationship between air quality, meteorological indicators, and COVID-19 to understand the interaction between COVID-19 and the atmospheric environment. COVID-19 and air quality, meteorological factors affecting the spread of COVID-19, air pollution, and human health are the main topics. Environmental variables have a certain impact on the spread of SARS-CoV-2, and the prevalence of COVID-19 has improved the atmospheric environment to some extent.

Emergency First Responders and Professional Wellbeing
Emergency first responders (EFRs) such as police officers, firefighters, paramedics and logistics personnel often suffer high turnover due to work-related stress, high workloads, fatigue, and declining professional wellbeing. Considering their professional roles, EFRs are often exposed to critical situations which pose a danger to their physical and mental health. As attempts to counter this through resilience programmes tend to have limited success, there is a need for further research into how organisational policies could change to improve EFRs’ professional wellbeing.

Indolepropionic Acid and Risk of T2DM & NAFLD
Gut-derived metabolites such as indolepropionic acid (IPA) are known to paly an important contribution in the development of metabolic diseases. The source of IPA depends on the dietary tryptophan intake, especially fiber, and presence of specific bacterial species in the human gut. In the present narrative review we elaborate on the role of IPA in type 2 diabetes (T2D) as well as non-alcoholic fatty liver disease (NAFLD). Researchers further explored the association of IPA with well known T2D-genetic variants and IPA-linked mechanisms affecting glucose metabolism and liver fibrosis.

Nutritional Considerations during Spaceflights
The main nutritional concerns during a spaceflight include the sufficient provision of energy to counteract the negative energy balance, which is often experienced by astronauts, the prevention of a deficiency in micronutrients, and fluid and sodium management. Furthermore, of utmost importance is the provision of specific nutrients to face spaceflight-induced pathophysiological events.

Food Loss and Waste
According to the Food and Agriculture Organization (FAO), about 1.3 billion tons of food, equivalent to one-third of worldwide food production, is lost or wasted. Along the value chain, food loss and waste (FLW) occur at every stage, including production, transportation, storage, processing, retailing, and consumption. Compared to developing countries, very few post-harvest losses occur in developed countries due to technical progress. However, in developing countries, about 40% of the total FLW comes from households.

Tourism, Ethnicity, and Gender in Yunnan
If a tourist looks for destinations with colourful and exotic lifestyles in China, then Yunnan would certainly be one of the more popular choices due to its high proportion of ethnic populations. Gender gaps appear to be reduced, with ethnic woman often conducting better business than their male counterparts. Additionally, ethnic women have the opportunity to explore the potentials of their own capacity. They come into contact with the outside world and gain better social capital, along with expanding choices, and social recognition.

Anti-CCR5 Therapy, Breast Cancer and Its Microenvironment
Breast cancer represents the most common malignancy among women in the world. The local microenvironment around the tumor plays a great role in cancer progression and invasion, representing a promising therapeutic target. CCL5 is a potent chemokine with a physiological role of immune cell attraction and has gained particular attention in R&D for breast cancer treatment. Its receptor, CCR5, is a well-known co-factor for HIV entry through the cell membrane and CCR5 blocking represents a mainstay of HIV treatment. Interestingly, CCL5 is currently described as key pro-oncogenic factor, especially in breast cancer. Several studies blocking the CCL5/CCR5 axis show cancer cells become less invasive and less malignant, with less oncogenic extracellular matrices.

Drug Delivery to the Brain
Chemotherapy as an adjuvant therapy that has largely failed to significantly improve outcomes for aggressive brain tumors; some reasons include a weak blood brain barrier penetration and tumor heterogeneity. There has been interest in designing effective ways to deliver chemotherapy to the tumor.

Hyaluronic Acid for the Treatment of Gingival Recession
In periodontal surgery, hyaluronic acid exhibited better results in complete root coverage and mean root coverage when compared to the control group. Gingival recession reduction, clinical attachment level, and keratinized tissue gain were significantly increased compared to the control groups.

Simulation-Based Education in Trauma Management
Trauma injuries are an important healthcare problem and one of the main leading causes of death worldwide. Researchers analyzed current practices in teaching trauma management using simulations, with the aim of summarizing them, identifying gaps and providing a critical overview on what has already been achieved.
