A new simple and rapid TLC-densitometric procedure for the separation and identification of betamethasone and its related substances, betamethasone-17,21-dipropionate, betamethasone-17-valerate, betamethasone-21-valerate and also betamethasone disodium phosphate was developed. One of the chromatographic systems proposed in this study, which has been satisfactory applied in separation of four pairs of examined compounds was silica gel 60F254 (E. Merck, Art. 1.05554) and a mixture containing chloroform-methanol-acetic acid (99.5%) in volume composition 28:5:0.5. Densitometric measurements were done using densitometer TLC Scanner 3 at 246 nm. The proposed method was checked in terms of its specificity for the determination of betamethasone-17,21-dipropionate and betamethasone disodium phosphate in commercially available products containing both compounds, separately, as active ingredients. The results showed that the method is suitable for qualitative analysis of betamethasone derivatives in simple and combined pharmaceuticals in various dosage forms e.g., lotion and injection solution. It also can be applied in quality control of pharmaceutical formulations of betamethasone and its related compounds in form of salts and esters.

With 25% of teenagers pregnant by age of 19 and about half of these married before their 18th birth day, Uganda exhibits one of the highest rates of teenage pregnancy and child marriage globally. Comprehensive data on the drivers and barriers to addressing repeat teenage pregnancies and early child marriages remains limited. Using the narrative inquiry approach, the paper explores the key socio-cultural drivers and barriers to addressing repeat teenage pregnancies and early/forced marriages among stakeholders in the districts of Mbale, Kween, Namayingo and Kalangala.

Background/objectives: Rural communities in the United States experience increased disparity of care for both general healthcare services and access to routine vaccines. Previous research has indicated a 40% lower vaccination rate in rural communities, as compared to urban counterparts. Having a better understanding regarding factors influencing lower vaccination rates in rural areas could help public health officials prepare for future vaccination efforts.

Vaccinating care home staff is essential to protect vulnerable residents by reducing infection risks and creating a safer care environment. However, vaccine hesitancy amongst staff remains a challenge, particularly since the COVID-19 pandemic raised concerns about side effects and vaccination mandates. This study examines how the pandemic influenced flu vaccine hesitancy amongst UK care home staff.

Human papillomavirus (HPV) is the most common sexually transmitted infection and plays a significant role in cervical, penile, anal, vaginal, vulvar, and oropharyngeal cancers as well as non-cancerous genital warts and genital dysplasia. In the United States, there are approximately 46,000 new HPV-related cancers a year. There is an effective vaccine to prevent over 90% of these cancers and other HPV-related diseases; however, those that are aged 18-26 have the lowest vaccine rates among eligible age groups.
