The regular consumption of net acid-producing diets can produce "acid stress" detrimental to human health. Alkalizing diets characterized by a negative potential renal acid load (also called low-PRAL diets (LPD)) enjoy uninterrupted popularity. However, the nutritional adequacy of said diets has rarely been assessed in large populations. Using data from the National Health and Nutrition Examination Surveys, we estimated nutrient intake in individuals consuming an LPD and contrasted the results in an age- and sex-specific manner to individuals on an acidifying diet (high-PRAL diet, HPD). Both groups were compared with the daily nutritional goals (DNG) specified in the 2020-2025 Dietary Guidelines for Americans (DGA). Our analysis included 29,683 individuals, including 7234 participants on an LPD and 22,449 participants on an HPD. Individuals on an LPD numerically met more nutritional goals than individuals on an HPD, yet both failed to meet the goals for several nutrients of public health concern (vitamin D and calcium). As opposed to individuals on an HPD, LPD consumers met the DGA recommendations for saturated fat and potassium. Individuals on an LPD consumed significantly more fiber than individuals on an HPD, as well as yielded a more favorable potassium-to-sodium intake ratio.

Bowen's disease (BD) is an intraepithelial squamous cell carcinoma (SCC) that commonly affects older individuals, with the vulva being a prevalent site in women. Lesions within the vagina pose a particular challenge for surgical treatment, often compromising both functional integrity and cosmesis. Photodynamic therapy (PDT) is an emerging, safe, and non-invasive technique utilizing a photosensitizer and a specific light source, widely applied in the treatment of malignancies and skin diseases.

Background: Fibromyalgia is a chronic pain condition characterized by widespread musculoskeletal pain, fatigue, and cognitive difficulties, affecting individuals across all age groups. Positive affect (PA) interventions have shown promise in enhancing emotional well-being and pain management in patients with diverse chronic pain conditions. However, the efficacy of internet-delivered PA interventions for individuals with fibromyalgia remains understudied.

Article Synopsis
- Echovirus 11 is causing increasing cases of neonatal sepsis in Europe and limited reports in West Africa, highlighting a significant public health issue.
- A study analyzed 23 E11 strains from West Africa using high-throughput sequencing, marking the first molecular characterization of the virus in the region and revealing a new recombinant strain.
- The research indicates that E11 has evolved into four distinct clades since the 1970s, with instances of the virus spreading from West Africa to Europe, underscoring the need for enhanced surveillance of enteroviruses in Africa.
Alterations in Glucagon Levels and the Glucagon-to-Insulin Ratio in Response to High Dietary Fat or Protein Intake in Healthy Lean Adult Twins: A Post Hoc Analysis.

Article Synopsis
- The study explores how different dietary fat intakes affect glucagon levels, crucial for lipid metabolism, using 92 twins on a low-fat diet (LFD) followed by a high-fat diet (HFD) and some on a high-protein diet (HPD).
- Results showed a significant reduction in glucagon levels during the LFD, while transitioning to the HFD led to a marked increase in glucagon and a decrease in free fatty acids. The HPD further elevated glucagon levels despite stable fasting amino acids.
- Overall, the findings suggest that a high-fat diet boosts glucagon levels and improves the glucagon-to-insulin ratio, potentially helping to prevent fat accumulation in the
