The qualitative theme "I had to fight for my VBAC" describes participants' accounts of navigating obstacles to VBAC, including finding a supportive provider and traveling long distances to locate a clinician and/or hospital willing to provide care. Participants cited support from providers, doulas, and peers as critical to their ability to acquire the requisite knowledge and power to effectively self-advocate.
Findings highlight the difficulties individuals face accessing VBAC within the context of a complex health system and help to explain why rates of attempted VBAC remain low.

This study aimed to explore the clinical implications of katanin P60 and P80 (katanin P60/P80) regarding their correlations with clinicopathological features and survival profiles in papillary thyroid carcinoma (PTC) patients.
Tumor tissue and paired adjacent tissue specimens were obtained from 172 PTC patients who underwent lobectomy or thyroidectomy. Besides, immunohistochemistry assay and immunoreactive (IR) score (multiplying staining intensity score by density score) were used to determine katanin P60/P80 expressions. According to IR score (from 0~12), katanin P60/P80 expressions were classified as low (IR score 0~3) and high (IR score 4~12) expressions.
Both katanin P60/P80 expressions were highly expressed in tumor tissue compared with adjacent tissue. Besides, tumor katanin P60 expression positively correlated with tumor katanin P80 expression. Tumor katanin P60 high expression correlated with larger tumor size, extrathyroidal invasion, advanced pT stage, pN stage, and pTNM stage, while no correlation of tumor katanin P60 expression with age or gender was observed; tumor katanin P80 high expression correlated with advanced pN stage and pTNM stage, whereas there was no correlation of tumor katanin P80 expression with age, gender, tumor size, extrathyroidal invasion, or pT stage. Furthermore, both tumor katanin P60/P80 high expressions correlated with shorter accumulating disease-free survival. As for overall survival (OS), neither tumor katanin P60 nor P80 expression correlated with OS.
Katanin P60/P80 measurement might assist with tumor management and prognosis surveillance in PTC patients.

Verification of new reagent lots is a part of the crucial tasks in clinical laboratories. The Clinical and Laboratory Standards Institute (CLSI) EP26-A guideline provides laboratories with an evaluation method for reagent verification. The purpose of this study was to compare the performance of EP26-A with our laboratory reagent lot verification protocol and get the final scheme.
16 chemiluminescence analytes including estradiol (E2), progesterone (P), ferritin (FER), cortisol (COR),carbohydrate antigen 153 (CA153), and free prostate-specific antigen (FPSA). were prospectively evaluated in two reagent lots. The laboratory's lot verification process included evaluating 5 patient samples with the current and new lots and acceptability according to a predefined criteria. For EP26-A, method imprecision data and critical differences at medical decision points were important factors affecting the sample size requirements and rejection limits.
The number of samples required for EP26-A was 3 to 12, of which P, CA153, and FPSA had increased by more than 5 samples compared with the current protocol. Of the 16 chemiluminescence analytes, 11 had higher rejection limits when using EP26-A than the current laboratory scheme. Our current protocol and EP26-A were in agreement in 32 of the 32 (100%) paired verifications.
The EP26-A protocol is an important tool to find the differences between reagent lots, and it makes up for the loopholes in the statistical efficiency, sample concentration and quantity, and the selection of rejection limits in the current protocol.

Hypoxia is one of the characteristics of microenvironmental changes after orthognathic surgery for fractures. HIF-1α is a main regulator of the hypoxic response and plays a crucial role in bone formation, remodelling, and homeostasis. AP1903 Osteoclasts participate in bone absorption and affect osteogenesis, and osteoclasts differentiate in a path from the oxygen-rich bone marrow to oxygen-deficient bone lesions. Thus, we aimed to study the key functions of HIF-1α in osteoclasts during mandibular healing after osteotomy.
The function of HIF-1α in osteoclasts during fracture healing in osteoclast-specific HIF-1α-conditional-knockout mice was investigated in mandibular osteotomy. Primary osteoclasts were used to explore the expression of HIF-1α and cardiotrophin-1 (CT-1) at both the mRNA and protein levels. The ability of BMSCs co-cultured with conditioned media from osteoclast-specific HIF-1α-knockout primary osteoclasts was detected using osteoclast-mediated osteogenesis experiments.
Hypoxia-inducible factor-1α increased osteoclastogenesis and bone resorption, and a delay in bone healing was found in osteoclast-specific HIF-1α-conditional-knockout mice compared with normal mice. HIF-1α-knockout primary osteoclasts inhibited bone resorption and CT-1 expression, and HIF-1α enhanced the osteoclast-mediated stimulation of BMSC differentiation by secreting CT-1.
Hypoxia-inducible factor-1α can play a key role in the physiology and pathogenesis of bone resorption by promoting osteoclastogenesis during fracture and influencing osteogenesis through CT-1 during bone healing.
