Art historians have long been fascinated by the idea that Hans Süss von Kulmbach, a German artist, created a portrait of John Boner, a wealthy Krakow banker. This notion has sparked intense debate and research into Kulmbach's connections to Poland. Two paintings in the collection of St Mary's Basilica in Krakow are at the center of this discussion: the Disputation of St Catherine of Alexandria and the Self-burial of St John the Evangelist. The concept of recognizability is key to understanding these paintings. In the premodern era, artists used various techniques to make their subjects easily identifiable. Mimesis, or the imitation of reality, was one approach, while schematism, or the use of symbols and codes, was another. Kulmbach's use of heraldry and costume in his paintings is also s

Female university students have been hit hard by the COVID-19 pandemic. Many have struggled with fear and anxiety, but what drives these feelings, and how do they cope? Researchers looked at 1000 female students to find out. The study found that fear of COVID-19 is linked to how students cope with the outbreak. But what's interesting is that physical activity and personal experiences with the virus can change this relationship. Students who were more active and hadn't had COVID-19 were less likely to be fearful and more likely to cope well. This suggests that lifestyle habits and personal experiences can shape how we respond to crises like COVID-19. Even after the initial emergency has passed, these factors can continue to influence our emotions and behaviors. So, what can we do to help

In the vast province of Sichuan, China, a unique challenge arises when it comes to tracking adolescent physical fitness. The sheer scale of fitness testing produces a multitude of measurements, making it difficult to translate these results into something meaningful for provincial surveillance. A team of researchers proposed a two-stage Bayesian framework to tackle this issue. The first stage involves using Bayesian confirmatory factor analysis to map test items onto four key fitness factors: strength, speed, endurance, and flexibility. This stage takes into account the error and variation in each item, providing a more accurate picture of adolescent fitness. The second stage uses Bayesian spatiotemporal hierarchical regression to model the outcomes of these factors. This stage helps ident

Emergency departments are always on the go, and pharmacists play a crucial role in ensuring patients receive the right medication. But what happens when pharmacists don't have time to review every medication list? A new triage model is being tested to see if it can improve efficiency without sacrificing accuracy. The model works by having pharmacy technicians gather medication histories, which are then reviewed by pharmacists only if they meet certain criteria. This way, pharmacists can focus on the patients who need their attention the most. But how accurate are these medication histories? A recent study looked at 150 medication histories collected using this triage model and found that 95% of them were accurate. The most common mistakes were omissions, additions, and incorrect dosages.

In a developing country, a 22-month-old girl faced a life-threatening condition. Chronic osteomyelitis, a bone infection, had taken hold of her tibia, causing severe damage. Doctors had to act fast to save her leg. The girl's tibia was badly damaged, with a 10-cm wound and necrotic tissue. Debridement, a surgical procedure to remove dead tissue, was performed. Cultures revealed the presence of Proteus mirabilis, a type of bacteria. To combat the infection, intravenous antibiotics were administered, followed by six weeks of oral therapy. Fibular tibialization, a surgical procedure, was performed to salvage the damaged tibia. K-wire fixation was used to stabilize the bone, and two weeks of postoperative antibiotics ensured the wound healed properly. Six weeks later, radiographs showed earl

The number of young people getting gastrointestinal cancers is rising fast in the US and worldwide. But what's behind this trend? Experts think it might have something to do with the way people live and the things they're exposed to in their environment. Young patients with GI cancers face some tough challenges. They often get diagnosed late, and their cancers are more aggressive than those in older people. They also get more intense treatment, but it's not clear if it really helps. On top of the medical issues, young patients with cancer often struggle with emotional and financial problems. They might worry about their relationships, fertility, and career goals. But doctors and hospitals often don't do enough to help them. Some big hospitals have started special programs to care for young

When it comes to endurance athletes, heat acclimation is a crucial part of their training. But just how effective is it in preparing them for the heat? A recent study looked at the effects of five days of heat acclimation on cardiovascular and thermoregulatory responses in athletes. The results were surprising. The study involved 14 healthy male athletes who were divided into two groups: one that underwent heat acclimation and another that exercised in thermoneutral conditions. The heat acclimation group spent five days in a hot environment, with a target core temperature of at least 38. 5°C. The other group exercised in normal conditions. The researchers measured various biomarkers to see how the athletes' bodies responded to the heat. They found that the heat acclimation group had lower

Urban forests are home to a diverse array of plant species, each with its unique characteristics and strategies for survival. In a recent study, researchers explored how different factors influence the way plants conserve nutrients in their leaves. They found that the way plants acquire and conserve resources is closely linked to their ability to resorb nutrients from their leaves. The researchers collected data from 154 woody species in a Chinese botanical garden, looking at factors such as leaf shape, size, and chemical composition. They also examined the types of mycorrhizal associations each plant had, as these can affect how plants acquire nutrients from the soil. The study revealed that plants with certain types of mycorrhizal associations tend to adopt more conservative strategies

Chronic diabetic wounds are a major complication of diabetes mellitus, characterized by persistent infection, inflammation, and impaired blood vessel growth. To combat this, researchers have developed a new type of microneedle that combines several functions to accelerate wound healing. These microneedles are coated with tiny particles called ruthenium dioxide nanozymes, which have antibacterial properties and can also generate oxygen. When inserted into a wound, the microneedles can penetrate bacterial biofilms and deliver the nanozymes directly to the infected area. This helps to kill bacteria, reduce inflammation, and promote the growth of new blood vessels. In animal studies, the microneedles were shown to be highly effective in treating diabetic wounds, leading to faster healing and i

Urban slums in low- and middle-income countries are home to a critical public health issue: child malnutrition. In Dhaka's Farmgate slum, researchers studied 450 children aged 0-59 months to understand the factors contributing to this problem. The study used a hierarchical framework to examine socioeconomic, household, and dietary determinants of malnutrition. Children were randomly selected, and their nutritional status was assessed using weight-for-height Z-scores and Mid-Upper Arm Circumference measurements. The results showed that 26. 7% of children were acutely malnourished. But what's surprising is that socioeconomic and dietary factors didn't play a significant role in malnutrition after adjusting for other variables. Instead, household overcrowding and recent diarrheal disease eme

When patients get discharged from the hospital, they often have to pick up their medications at the pharmacy. But what if the pharmacy came to them? A study looked at how this approach, called meds-to-beds, affects hospital readmissions. The study focused on patients who were discharged between January 1 and July 30, 2022. Researchers compared two groups: those who received their medications through the meds-to-beds program and those who didn't. They found that patients in the meds-to-beds group had a lower rate of readmission to the hospital within 30 days. In fact, only 13. 3% of patients in the meds-to-beds group had a readmission within 30 days, compared to 27. 1% of those who didn't receive their medications through the program. This difference was statistically significant, meaning i

Families living in multicultural and regional/rural communities of Australia often struggle to access social and healthcare services. This can lead to unmet social care needs that have a significant impact on their lives. A recent study aimed to explore the factors that contribute to these unmet needs and the role of parental mental health in families from these communities. In the study, researchers analyzed data from a randomised controlled trial conducted among parents/carers of children from culturally and linguistically diverse (CALD) communities of South Western Sydney and rural/regional communities of Murrumbidgee. The researchers used a survey called the WE CARE survey to measure the level of unmet social care needs. They found that 61% of the 288 participants reported having one
