Doctors in South Africa warn: antibiotics do not treat most seasonal viral illnesses

Patients suffering from Crohn's disease show an increased frequency of postoperative complications in the artificial joint area, known as periprosthetic infections. According to the study data, this risk increases by an average of 38 percent. It is important to note that ulcerative colitis did not demonstrate an influence on the probability of adverse outcomes.

General Characteristics of Digestive Diseases

Inflammatory bowel diseases, including Crohn's disease and ulcerative colitis, have become much more common in recent decades. These conditions are associated with impaired immune regulation in the digestive tract. In addition to GI problems, both pathologies often manifest with extraintestinal symptoms. For example, bone mineralization deficiency affects the musculoskeletal system, increasing the danger of fractures. Furthermore, people with inflammatory bowel diseases often face degenerative changes in their joints, which may require total endoprosthesis.

Risks of Postoperative Complications

There is uncertainty regarding the level of risk of postoperative complications following such interventions in this group of patients. It was noted that microbiome disturbances characteristic of inflammatory bowel diseases can increase the likelihood of infections at surgical sites. Additionally, immunological disorders and the use of immunomodulatory drugs, which are usually prescribed for treating these diseases, may contribute to an increased risk of infectious complications after joint surgery.

Study Methodology

A team of scientists led by Nathaniel Heckmann from the University of Southern California conducted a study on the link between inflammatory bowel diseases and the risk of periprosthetic infection—a complication after joint endoprosthesis. The researchers used a large national representative database. Their goal was to establish a correlation between these diseases and infection within 90 days after elective hip or knee joint endoprosthesis.

Data and Analysis Results

The study included 10,040 patients scheduled for hip or knee endoprosthesis who had a history of inflammatory bowel diseases. Among them, 54.64 percent had Crohn's disease, and 45.36 percent had ulcerative colitis. These patients were compared with a control group of 70,203 individuals. Specifically, 5,474 patients with Crohn's disease were matched with 38,230 control patients, and 4,555 patients with ulcerative colitis were matched with 31,865 control patients.

Univariate regression analysis showed that within 90 days after surgery, the incidence of periprosthetic infection in patients with inflammatory bowel diseases was similar to the control group (0.71 percent versus 0.61 percent; p = 0.245). However, a sub-analysis revealed that in patients with Crohn's disease, the rate of periprosthetic infection was higher than in the control group (0.86 percent versus 0.62 percent; p = 0.043). No such association was found in the case of ulcerative colitis (0.53 percent versus 0.64 percent; p = 0.365).

Conclusions and Future Steps

After applying multivariate models adjusted for confounding factors, a statistically significant increased frequency remained in patients with Crohn's disease. The results of this study emphasize the need for pre-operative risk stratification and optimization of treatment for patients with Crohn's disease requiring joint endoprosthesis. Scientists plan to continue research to determine the biological and mechanistic basis of the identified relationship. It is also mentioned that a diet restricting daily caloric intake to 1090 kilocalories can effectively reduce the activity of Crohn's disease, which could potentially help prevent increased infection risk.

Agriculture Minister Willie Aucamp announced the official launch of a self-vaccination application intended for livestock owners. The Department of Agriculture introduced a new online portal that will allow livestock farmers to obtain official authorization to vaccinate their animals against Foot-and-Mouth Disease (FMD), which is part of South Africa's efforts to combat the disease.

Increased Farmer Control

Agriculture Minister Willie Aucamp noted that this live system will give farmers greater control over protecting their herds and will help contain potential FMD outbreaks faster. He emphasized that this system transfers critical control to farmers, allowing them to request official vaccination authorization and prevent FMD outbreaks more promptly than before.

Expansion of Private Sector Participation

Aucamp stated that the launch marks the beginning of broader measures to involve the private sector in combating the spread of FMD. He assured all interested parties that the Department of Agriculture intends to facilitate private sector participation in this fight.

Registration and Reporting Process

Thanks to the new system, cattle owners and managers can register on the FMD reporting platform and follow a structured application process that complies with South African biosecurity requirements, legal provisions, traceability measures, and vaccination reporting obligations. The process consists of three stages.

Firstly, cattle owners or managers must apply for 'Authorized Person' status through the FMD reporting system, which grants them the right to carry out FMD vaccinations in accordance with current legislation. After receiving approval, they are required to notify the provincial director of veterinary services or the relevant state veterinarian no later than five days before conducting the vaccination. This notification can be submitted via the online portal or in writing.

Upon completion of the vaccination, authorized persons must submit a vaccination report within 14 days. This report must specify the vaccines used, the number and type of vaccinated animals, and the location of the procedure. These reports can also be submitted electronically or in hard copy.

Alternative Reporting Systems

Aucamp reported that farmers also have the option to use approved private sector reporting platforms, including those operated by RMIS, SAAI, and Buffalo Analytics, provided these systems are approved by the Director of Animal Health. The Minister clarified that all information obtained from any third-party system will be transmitted to the Department of Agriculture (DoA) and uploaded into its system. The responsibility for verifying the approval of the chosen system lies with the cattle owners and managers.

Monitoring and International Recognition

According to Aucamp, the data collected through the reporting systems will help the government monitor the progress of the national vaccination program and support South Africa's efforts to restore international recognition of its animal health status. It will also enable the effective provision of up-to-date information about the success of South Africa's vaccination program to the World Organisation for Animal Health (WOAH) when applying for FMD-free status with vaccination.

Support and Funding

The Minister called on organized agricultural associations to collaborate closely with approved vaccine importers to determine the required number of doses for their members, allowing suppliers to plan procurement and distribution more effectively. He also strongly recommended that vaccine importers engage with veterinarians to assess demand in various regions and ensure adequate vaccine availability.

Under the voluntary vaccination program, farmers who choose to vaccinate their livestock are responsible for purchasing the vaccines. However, Aucamp stressed that the government will continue to supply vaccines to areas where new FMD outbreaks are detected, as well as to farmers who cannot afford the vaccination.

During flu season in South Africa, when there is a surge in coughing, fever, and fatigue, many people turn to simple and nutritious home-cooked meals for support and comfort. Among these dishes, warm vegetable stew is popular as it helps alleviate flu symptoms and restore strength.

Ingredients for Preparation

This dish requires carrots, onion, garlic, celery, spinach, tomatoes, ginger, turmeric, black pepper, cayenne pepper, cinnamon, and cloves. These components form the basis of a dish that simmers slowly, providing the body with comfort and constant natural nourishment during illness.

Step-by-Step Stew Preparation

First, prepare the base: chop the carrots, onion, celery, and garlic. Carrots provide beta-carotene to support immunity, while onion and garlic release warming compounds associated with antimicrobial properties, and celery aids in hydration.

Starting the Simmer and Adding Spices

In a pot, heat a little oil over medium heat, then add the onion and garlic to let them soften slowly. This process releases aromatic substances and beneficial plant compounds, forming a warming base for the stew. Next, stir in the carrots, turmeric, cinnamon, and cloves. Turmeric contains curcumin, which is associated with anti-inflammatory action, and cloves introduce aromatic oils that promote soothing.

Adding Liquid and Vegetables

Pour water or vegetable broth into the dish until the vegetables are covered. After bringing it to a gentle boil, reduce the heat to a slow simmer. When the carrots begin to soften, add the chopped celery and tomatoes. During cooking, tomatoes release lycopene—a powerful antioxidant whose bioavailability increases upon heating.

Finishing the Cooking and Balancing Flavor

The stew should simmer slowly for 20–30 minutes until all ingredients blend into a rich, warming broth that supports hydration and comfort. At the very end, add the spinach, allowing it to wilt slightly for one to two minutes to preserve Vitamin C and folate, which are important for immune recovery. Before serving, finish the dish by adding ginger, black pepper, and salt. Ginger helps soothe the throat and relieve congestion, while black pepper enhances nutrient absorption, especially curcumin.
