Intra Ovarian Muse Cell Injection for Perimenopause Symptom Relief and Ovarian Function Restoration (MUSE-OVARY)

This observational study examines the safety and effects of injecting Muse cells (a type of naturally occurring stem like cells found in adult tissues such as fat or bone marrow) directly into the ovaries of women aged 28 to 70 who are going through peri-menopause. Perimenopause is the transition time before menopause when hormone levels fluctuate, periods become irregular, and many women experience symptoms like hot flashes, night sweats, sleep problems, mood changes, and reduced energy. Current treatments mainly manage symptoms but do not restore natural ovarian function. Muse cells have special properties: they can help repair tissues, reduce inflammation, support cell energy production, and promote a healthier environment in the ovaries. In this study, women who choose to receive ultrasound guided Muse cell injections into their ovaries as part of their own regenerative care will be carefully followed. Researchers will monitor safety, hormone levels (such as FSH, estrogen, and AMH), ovarian follicle counts via ultrasound, menstrual patterns, and quality of life improvements using questionnaires. The study does not assign treatment - participants and their doctors decide on the procedure, and information is collected in a standardized way over 24 months (with longer safety follow-up). The goal is to gather real world data on whether this approach can help stabilize hormones and support ovarian tissue during perimenopause. No placebos or experimental drugs are used in this observational study.

Effectiveness of a Vaginal Gel on CIN1/2 Regression and HPV Clearance.

The goal of this clinical trial is to evaluate whether a Coriolus versicolor-based vaginal gel promotes regression of CIN1/CIN2 and facilitates HPV clearance in women aged 30-50 years diagnosed with CIN1 or CIN2 and HPV. In addition, the study will assess patient satisfaction, treatment compliance and characterize the vaginal microbiome. The primary outcomes therefore is: * the regression of the cervical dysplasia from baseline to the follow-up (6 months), which will be assessed through either liquid-based cytology and/or histopathology (biopsy). * HPV clearance from baseline to follow-up (6 months) In this randomized controlled study, eligible participants will be randomized 1:1 into two groups: 1. Intervention group: Women (n=35) will apply a CV-based vaginal gel (Papilocare®) daily for 21 days for 3 months. Afterward, the gel should be used every other day for an additional 3 months. Every month includes a 7-day break due to menstruation (28 days cycle). 2. Control group; Women (n=35) will follow the conventional "wait and see" approach.

Study on Sex-specific, Individualized Dose Calculation of Contrast Agent in CT Examinations

A large proportion of radiological CT examinations require the intravenous administration of iodine-containing X-ray contrast medium. According to current guidelines, the amount required for CT examinations in the (portal) venous phase is calculated on the basis of body weight (e.g. 0.2-0.4 g iodine/kg body weight), but a standardized application dose of the contrast agent is often also used. In earlier studies, the investigators found that the iodine contrast in vessels and organs achieved with a standardized amount of contrast agent differs significantly between women and men. On average, women showed around 10% higher iodine contrast than men of the same height and weight. The investigators attribute these differences to physiological, sex-specific differences in blood volume. For example, the blood volume of a woman 175 cm tall and weighing 75 kg is approx. 400 ml less than that of a man of the same height and weight (approx. 4.6 vs. 5.0 l, calculated according to Nadler). Taking blood volume into account, sex was no longer a significant influencing factor in a retrospective cohort (n=274). The investigators would now like to investigate these results in a prospective study. For this purpose, two groups of patients with a clinical indication for a contrast-enhanced CT scan in the venous phase will be compared: 1. control group with regular weight-adjusted (n = 200) 2. study group with dosing according to blood volume (n = 200). The hypothesis is that the application scheme adapted to the blood volume leads to a more homogeneous contrasting of women and men. In order to quantify this effect, the iodine contrast values of both groups will be quantitatively analyzed, taking into account other influencing variables (height, weight). The investigators hope that this approach will reduce or even eliminate the observed sex-specific differences. This would lead to a sex-equal contrast based on an individualized amount of contrast medium.
