Objective: To describe a method of calculating and registering the dose of radiation used in Pamplona County in pediatric examinations, and to show the results obtained one year after its implementation.
Material And Methods: The effective dose was calculated by a program that uses the pediatric files of the United Kingdom's National Radiation Protection Board. This program, incorporated into the Computerized Clinical History, enables an Individual Dosimetric History to be calculated for the entire pediatric population. The effective dose figures were correlated with the risk of radio induced mortal cancer using the estimations of the International Commission on Radiological Protection.
Results And Discussion: In one year, 9681 children received 22667 exposures to X-rays in Pamplona County. The annual collective dose on the population of children in the area was 3.1 sieverts, and the mean dose per inhabitant was 0.054 millisieverts. We report the number of each kind of examination for the year, together with the resulting mean effective dose and the risk of mortal cancer it involves. The largest doses were obtained from CT examinations, gastroduodenal studies, and telemetry of the entire spine. We describe and discuss the risk involved in radiological examinations.
Conclusions: Modern information technology techniques enable individual dosimetric histories to be created using the most modern systems of measurement and registration.

Introduction: Current trends of delaying childbearing and the increasing incidence of endometrial cancer in nulliparous woman necessitate research and development of fertility sparing treatments. Hormonal therapy with progestins offers an alternative to surgical treatment for a select group of patients of reproductive-age, who wish to preserve their reproductive potential.
Materials And Methods: The study evaluates the effectiveness of medroxyprogesterone acetate therapy in patients with early-stage endometrial cancer, atypical endometrial hyperplasia or atypical polypoid adenomyoma, seeking to preserve fertility.

This study aimed to compare the efficacy and safety between high-dose intravenous iron and oral iron in treating iron deficiency anemia (IDA) . This prospective randomized controlled study (1∶1) enrolled 338 patients with IDA at The First Affiliated Hospital of Soochow University, Suzhou Hongci Hematology Hospital, and Huai'an Second People's Hospital from June 1, 2022, to January 19, 2024. Of all the patients, 169 received high-dose intravenous iron therapy and 169 received oral iron treatment for 12 weeks of observation.

Our understanding of the implications of gestational Cannabis exposure (GCE) remains unclear as Cannabis use increases worldwide. Much of the existing knowledge of the effects of GCE has been gained from preclinical experiments using injections of isolated Δ-tetrahydrocannabinol (THC) at relatively high doses. Few investigations of the effects of GCE to smoke from the whole Cannabis flower have been conducted, despite this being the most common mode of human consumption.

Assisted reproductive technology (ART) is widely used to address infertility and enhance reproductive outcomes in livestock. Among various ART techniques, in vitro maturation (IVM) is commonly used to obtain high-quality oocytes but is susceptible to oxidative stress. In traditional Chinese medicine, Rhizoma Atractylodis Macrocephalae (Bai Zhu) is used to enhance maternal and fetal health.

Population exposure to plastics is increasing, and plasticizers are frequently detected in humans as important ingredients of plastic products. However, patterns of exposure to harmful ingredients of plastics and their effects on neurofilament light chain (NFL), a marker of active brain pathology, are currently inconclusive. Herein, we employed a range of statistical methods to thoroughly investigate the impact of 24 plastic hazardous ingredients and their varying exposure patterns on NFL concentrations in the blood of the general population in 533 participants.
