Background: No studies have been published comparing the U- and H-type methods of the TVT SECUR (TVT-S) procedure.
Objective: Our aim was to compare the efficacy and safety of the two types of TVT-S for female stress urinary incontinence (SUI).
Design, Setting, And Participants: Women with urodynamic SUI were enrolled in this 12-mo multicenter randomized study.
Intervention: Subjects were randomly allocated to either the U- or H-type method of TVT-S.
Measurements: Pre- and postoperative evaluations included a standing stress test, the Sandvik questionnaire, the Incontinence Quality of Life (I-QOL) questionnaire, and the International Consultation on Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS). Patients' satisfaction and complications were evaluated. Objective and subjective cures were defined as no leakage on the stress test and responses on the Sandvik questionnaire, respectively. We compared the surgical outcomes between the two methods.
Results And Limitations: Of 285 women, 144 had the U-type method and 141 had the H-type method. Objective cure rates were 87.5% for the U-type method and 80.1% for the H-type method (p=0.091). Subjective cure rates were 77.1% for the U-type method and 75.7% for the H-type method (p=0.786). Improvement in I-QOL and domain scores of the ICIQ-FLUTS (filling and incontinence sum, QOL score), and patients' satisfaction favored the U-type method. There were three cases of intraoperative vaginal wall perforation, one case of increased bleeding, and three cases of temporary postoperative retention. A power calculation was not performed, and some baseline characteristics were not balanced between the two methods.
Conclusions: Both methods of TVT-S provided comparable cure rates for female SUI. However, QOL and treatment satisfaction favored the U-type method.
Trial Registration: The protocol of this study was not registered.

The final outcomes of supramolecular assembly are determined by the pathways and the formation of intermediates during the assembly process. We studied pathway complexity involving two consecutive pathways in supramolecular polymerization of naphthalene-diimide (NDI) derivative molecule. Depending on preparation methods anisotropic aggregates of J-type nanorods (Agg I) or more flexible H-type nanofibers (Agg II) are obtained from the identical initial state in solution of methyl cyclohexane (MCH) or MCH/CHCl3 mixtures.

Objective: To explore the mechanism of hyperbaric oxygen therapy in inhibiting subchondral bone angiogenesis and delaying the progression of osteoarthritis through the PHD2/HIF-1α signaling pathway.
Methods: Mice were randomly divided into three groups (control group, osteoarthritis group, and hyperbaric oxygen treatment group). The effect of hyperbaric oxygen therapy on osteoarthritis was evaluated using Micro-CT, Safranin O-Fast Green staining, and detection of osteoarthritis inflammation markers (MMP-13, ADAMTS-5, Col2a1, and Aggrecan).

In this work, we present the synthesis, solid-state characterization, and studies of two pyrazole derivatives: 5-(2-methylphenoxy)-3-methyl-1-phenyl-1-pyrazole-4-carbaldehyde (I) and 5-(4-methylphenoxy)-3-methyl-1-phenyl-1-pyrazole-4-carbaldehyde (II). The molecular crystal properties, in terms of intermolecular hydrogen bonds and other weak interactions, are analyzed using single crystal X-ray diffraction. The Hirshfeld surfaces computational method is used to quantify the intermolecular interactions, density functional theory for theoretical structural optimization, and its comparison with the experimental structure and studies using docking and molecular dynamics studies of I and II with CDC7-kinase.

To analyze the clinical significance of molecular classification and hereditary phenotype in endometrial carcinoma (EC) based on high throughput sequencing (NGS). 97 EC samples were collected retrospectively from December 2019 to October 2022 in China-Japan Friendship Hospital. NGS technique was used to analyze the molecular classification, POLE hypermutation, microsatellite high Instability/mismatch repair dysfunction (MSI-H/MMRd), P53 protein abnormality (P53 abn), and non-specific molecular profile (NSMP).

Industrial production of hydrogen peroxide (HO) is energy-intensive and generates unwanted byproducts. Herein, an alternative production strategies of HO are demonstrated in a Zn-air and a photoelectrochemical cell. Employing an optimally produced reduced graphene oxide (rGO) electrocatalyst@air-cathode, an impressive power density of 320 Wm (geo = geometric area) is achieved along with a high HO production rate of 3.
