AI Article Synopsis
- The study aimed to identify factors influencing early breast development in girls, potential risks for converting from precocious thelarche (PT) to idiopathic central precocious puberty (ICPP), and timely intervention methods to minimize ICPP cases.
- Researchers analyzed data from 50 children with PT and 50 control subjects, measuring various hormones and vitamin D levels over a year to see their relationship with early breast development.
- Findings indicated that factors like vitamin D deficiency, obesity, screen time, dietary habits, and emotional sensitivity could contribute to early breast development, emphasizing the need for monitoring and addressing these factors to promote healthy growth in children.
Article Abstract
Objective: To investigate and analyze the influencing factors of simple early breast development in girls, to discover the dangers and triggers of PT conversion to ICPP, and the time point of transformation in order to detect and prevent the occurrence of transformation in advance and reduce the incidence of idiopathic central precocious puberty. Ensure children's physical and mental health and normal growth and development.
Methods: A total of 50 children with PT admitted to our hospital from April 2019 to December 2020 were included in the study group, and 50 children with physical examination during the same period were selected as the control group. All children were tested for vitamin D, androstenedione, dehydroepiandrosterone, 17-hydroxyprogesterone, leptin, IGF-I., and IGFBp-3 at 3, 6, 9 and 12 months after the diagnosis of PT.
Results: Vitamin D levels decreased in the child, indicating that vitamin D deficiency was closely related to the age of breast development in ICPP girls and may be related to serum P-FSH, P-LH and E2 levels. Increased levels of IGFBp-3 indicate that these indicators are involved in the onset of ICPP. Children have a higher BMI, watch idol dramas or play mobile games longer, often eat snacks containing preservatives, have a fishy diet, are more irritable and sensitive, and dry stools are also risk factors affecting the early development of simple breasts in girls.
Conclusion: The influencing factors leading to simple, early breast development in girls include vitamin D, androstenedione, dehydroepiandrosterone, 17-hydroxyprogesterone, leptin, IGF-I., IGFBp-3, and should be combined with the progression of breast Tanner staging (complete regression, recurrent, and persistent), height growth rate, bone age, Uterine and ovarian B ultrasound, sex hormones, etc., warn of the conversion of PT to ICPP, and ensure children's physical and mental health and normal growth and development.

Background: Neoadjuvant chemotherapy (NACT) is the standard-of-care treatment for patients with locally advanced breast cancer (LABC), providing crucial benefits in tumor downstaging. Clinical parameters, such as molecular subtypes, influence the therapeutic impact of NACT. Moreover, severe adverse events delay the treatment process and reduce the effectiveness of therapy.

Background: Breast cancer (BC) has exhibited varied epidemiological trends based on distinct age categories. This research aimed to explore the incidence and mortality rates of BC within pre-defined age groups in the Brazilian population.
Methods: BC incidence trends were assessed from 2010 to 2015 using Brazilian Population-Based Cancer Registries, employing age-standardized ratios and annual average percentage change (AAPC).

We conducted a comparative study of the mammary gland microbiota in female Wistar rats and the microbiota associated with breast cancer (BC) induced by the administration of N-methyl-N-nitrosourea, after surgical treatment, photodynamic therapy (PDT), and chemotherapy (CT). Selective nutrient media and a smear-fingerprint technique were used to study the microbiota. Staphylococcus, Streptococcus, and Lactobacillus were found in the mammary glands of intact rats.

Effective targeting of somatic cancer mutations to enhance the efficacy of cancer immunotherapy requires an individualized approach. Autogene cevumeran is a uridine messenger RNA lipoplex-based individualized neoantigen-specific immunotherapy designed from tumor-specific somatic mutation data obtained from tumor tissue of each individual patient to stimulate T cell responses against up to 20 neoantigens. This ongoing phase 1 study evaluated autogene cevumeran as monotherapy (n = 30) and in combination with atezolizumab (n = 183) in pretreated patients with advanced solid tumors.

Objective Endometrial lesions are a frequent complication following breast cancer, and current diagnostic tools have limitations. This study aims to develop a machine learning-based nomogram model for predicting the early detection of endometrial lesions in patients. The model is designed to assess risk and facilitate individualized treatment strategies for premenopausal breast cancer patients.
