In response to the insightful comments made by Dr. Abid et al. on our article "Investigation of Vitamin D Levels in Men with Suspected Infertility", we address several key points concerning the generalizability and methodology of our study. Dr. Abid et al.'s critique primarily focused on the single-center nature of our research, regional variations in ultraviolet (UV) exposure, dietary factors affecting vitamin D levels, and the sample size of our study. We discuss the inherent value and controlled environment of single-center studies while acknowledging the need for multi-center validation. Additionally, we explain our consideration of sun exposure and dietary intake in our analysis, and recognize the importance of larger, more diverse studies to strengthen our findings. Our response aims to clarify these aspects and emphasize the significance of vitamin D in male infertility, encouraging further research in this field.

In 2017, Kidney Disease: Improving Global Outcomes (KDIGO) published a Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD). Since then, new lines of evidence have been published related to evaluating disordered mineral metabolism and bone quality and turnover, identifying and inhibiting vascular calcification, targeting vitamin D levels, and regulating parathyroid hormone. For an in-depth consideration of the new insights, in October 2023, KDIGO held a Controversies Conference on CKD-MBD: Progress and Knowledge Gaps Toward Personalizing Care.

Introduction: This study investigated the role of fibroblast growth factor 23 (FGF23)/Klotho in the mortality of patients hospitalized with coronavirus disease 2019 (COVID-19), excluding those with chronic kidney disease (CKD).
Methodology: A prospective cross-sectional study was conducted from April 2021 to May 2022. Patients who tested positive for COVID-19 via polymerase chain reaction and were hospitalized, were classified into two groups (survivors and non-survivors) at the end of their hospital follow-up.

The objective of this retrospective, database study was to characterize the rate, magnitude and timeline of increases in parathyroid hormone (PTH) levels post-denosumab (DMAb) vs. zoledronic acid (ZA) injection in patients with osteoporosis and near normal baseline PTH. Included were osteoporotic females, ≥50 years, initiating treatment with 60 mg DMAb or 5 mg ZA.

Purpose: The correlation between serum vitamin D and mortality in patients with osteopenia or osteoporosis remains unclear. Therefore, this study examined the relationship between serum 25-hydroxy vitamin D [(25(OH)D] and mortality in patients with osteopenia or osteoporosis.
Methods And Result: This prospective cohort study included patients with osteopenia or osteoporosis from the National Health and Nutrition Examination Survey from 2001 to 2018.

B vitamins are essential for energy metabolism, nervous health, blood production, and the immune system. Their quantification in nutritional supplements and food is mandatory to manage a correct daily intake and dosage. In this study, a fast and sustainable method for the analysis of 8 B vitamins (VB, VB, VB, nicotinamide, VB, VB, VB, VB) in real samples using a 2D-carbon microfiber fractionation system combined with a triple quadrupole mass spectrometer (2DμCFs-QqQ-MS/MS) is presented.
