Atraumatic Zirconia Abutment Versus Customized Composite Healing Abutment in Maxilla or Mandible.

40 patients are included in the study, 20 patients in group 1 (=closure with composite material shaper; test group) and 20 patients in group 2 (=closure with custom-made zirconia oxide abutment; control group). Randomisation envelopes will be used for randomisation. Device under study: Straumann BLX, Roxolid® , SLActive® dental implants with a diameter of 3.5, 3.75, 4, 4.5 mm are used. Allogenic bone botiss maxgraft® cortical granules are used as graft material. Inclusion criteria: 1. Males and females at least 18 years of age or older. 2. One implant per patient. 3. Prior to any study-related activity, the subject must voluntarily sign informed consent, be willing and able to attend scheduled follow-up visits, and agree to the collection and analysis of pseudonymised data. 4. Lateral individual teeth (premolars and molars). 5. Class I extraction socket (intact buccal wall) or class II (1/3 of buccal wall). 6. The gingival contour of the tooth to be extracted - without recession. 7. Adjacent anterior teeth have no periodontal loss. 8. There are no implants in the adjacent teeth. 9. Non-traumatic tooth extraction, which results in intact walls of the socket. Exclusion criteria: 1. Deep occlusion (severe, class II). 2. The patient smokes a lot (more than 10 cigarettes per day). 3. Systemic disease (osteoporosis). 4. No initial stability has been achieved after the implant insertion procedure.

Clinical Performance of Urine HPV Testing in Males

Human papillomavirus (HPV) infection is one of the most prevalent viral infections of the genital tract, primarily transmitted through sexual contact. Research indicates that individuals engaging in sexual activity have a lifetime probability of HPV infection as high as 85% to 90%. While extensive and in-depth investigations have been conducted on HPV infection in women, epidemiological studies focusing on male HPV infection remain relatively scarce. Many men with HPV are asymptomatic; reports suggest that approximately 10.5% of men in China are infected with HPV, yet only about 1% exhibit related symptoms. This substantial population of asymptomatic and unaware patients poses significant challenges for the prevention and control efforts regarding HPV in China. Furthermore, evidence suggests an association between HPV infection and conditions such as condyloma acuminatum, penile intraepithelial neoplasia (PeIN), penile cancer (PA), and even infertility among male patients. In current clinical practice, detection of HPV typically involves collecting exfoliated cells from the external genitalia via swabs. The discomfort associated with this sampling method and its procedural complexity often deter many asymptomatic men from undergoing penile swab testing for HPV, resulting in low compliance rates. Self-sampling urine tests offer advantages including convenience, ease of use, painlessness, and non-invasiveness; thus they may serve as a viable alternative approach. In prior research endeavors, we successfully established a detection system utilizing female urine samples for identifying HPV presence. Consequently, this study aims to further refine this detection system to develop a stable and reliable methodology for detecting HPV using self-collected urine samples from males. Through this investigation not only do we seek to validate the feasibility of employing self-collected urine samples for detecting male HPV infections but also assess the accuracy and practicality of home-based self-testing methods among subjects-ultimately providing novel strategies for male-specific HPV detection

SEx-specific Differences in Cardiac Surgery Patients (SECS).

The aim of this study is to evaluate the differences between females and males undergoing cardiac surgery. The investigators will look at perioperative factors such as adaption of body weight, previous medical history, pharmacokinetics, transfusion, coagulation, cardiopulmonary bypass (CPB) related factors, cardiac function, inotropic requirements, risk, and outcome scores as well as morbidity and mortality at sort-term (within 30 days) and long-term (90 days and 1 year).

Efficacy of Transcutaneous Vagus Nerve Stimulation Paired With Tailor-Made Notched Music Therapy Versus Tailor-made Notched Music Training for Chronic Subjective Tinnitus

This clinical study is a prospective, multicenter, randomized, controlled, double-blind clinical study. Sun Yat Sen Memorial Hospital of Sun Yat sen University was the central unit, and Nanjing First Hospital, Sun Yat Sen people's Hospital, Guanfzhou Panyu central Hospital and Zhuhai integrated traditional Chinese and Western medicine hospital were the cooperative units. In this study, 388 patients with chronic subjective tinnitus were recruited. In view of chronic subjective tinnitus, a common ear disease, the study gave the patients three months of treatment with transcutaneous vagus nerve stimulation paired with tailor-made notched music therapy or tailor-made notched music training alone. By comparing the changes of subjective scale scores related to tinnitus before and after treatment in patients receiving two different therapies, such as THI, VAS, BAI, BDI, PSQI, to evaluate the efficacy of the two therapies, so as to judge whether transcutaneous vagus nerve stimulation paired with tailor-made notched music therapy is better than tailor-made notched music training alone. In addition, the study will continue to follow up the patients after the treatment for one year to observe the difference in the long-term sustained efficacy of the two therapies. This clinical study will also evaluate the two therapies from the perspective of compliance and safety, and explore the factors that affect the efficacy of the two therapies.
