We aimed to assess the feasibility, safety, and operator feedback of a novel star-shaped high-density mapping catheter containing 48 platinum-iridium mapping electrodes distributed across eight spines.
This prospective, single-arm, first-in-human study was conducted at five European sites. Primary endpoints were completion of pre-ablation mapping requirements, obtaining clinically indicated mapping with the new catheter without resorting to non-study mapping catheters, and incidence of serious adverse events (SAEs). Physician feedback survey assessed catheter performance, including deployment, ease of use, and mapping results. The subjects were followed for 7days post-procedure.
Of 31 patients enrolled (11 ventricular tachycardia [VT], 10 scar-related atrial tachycardia [AT]/atypical atrial flutter [AFL], and 10 persistent atrial fibrillation [PsAF]), 28 had study catheter inserted for mapping purposes. Pre-ablation mapping was achieved in 23/28 patients (82.1%). Median of total pre-ablation mapping times were 121.0, 72.5, and 31.5min for the VT, scar-related AT/atypical AFL, and PsAF subgroups, respectively. More than two-thirds of mapping points acquired were used to generate CARTO maps relevant for ablation. All 16 patients who had conduction channel(s), gaps(s), or critical isthmus identified had the areas successfully mapped. The ability to deploy, maneuver, and reach the atria and ventricles using the catheter was rated positively for most procedures. Only one SAE (heart failure) was reported, unrelated to the device.
The study results demonstrate the feasibility of the OCTARAY catheter to successfully map complex arrhythmias with good safety profile. Operator feedback indicates satisfaction with ease of use and maneuverability of the catheter.

Protrusion of the lateral contour of the pancreatic head is a pancreatic morphological abnormality, which is known as rare shape atypia. We present a rare case of protrusion of the lateral contour of the pancreatic head, which was challenging to distinguish from an ectopic pancreas.
The patient was a 40-year-old man with a history of acute pancreatitis that occurred twice in the past. He complained of epigastric pain since the day before the visit; his blood workup showed high serum amylase level and a CT scan revealed a 25-mm-large mass with contrast effect from the anterior wall of the gastric pylorus to the duodenum and increased surrounding fatty tissue density. Endoscopic ultrasonography revealed a mass lesion in the gastric pylorus with continuity with the gastric wall and suspected partial continuity with the pancreatic head. Thus, the possibility of pancreatic morphological abnormality or an ectopic pancreas was considered. Following which, resection was attempted and intraoperative findings showed a wide extension of the pancreatic parenchyma from the pancreatic head to the anterior wall of the gastric pylorus to the duodenal bulb. Since the patient only had mild pancreatitis, the resection was judged to be too invasive and was completed by exploratory laparoscopy.
Even if the findings on preoperative CT are suspicious for an ectopic pancreas or tumor, a pancreatic morphological abnormality, such as a protrusion of the lateral contour of the pancreatic head, should be included in the differential diagnosis.

In the current study, we interviewed an ethnically diverse sample of 168 3-5 year-olds (88 girls, 80 boys) to address this gap in the literature. Results showed that boys as young as age 3 generally valued strength more than girls (1) boys, on average, said it was more important to be strong than girls did, and (2) boys were more likely to prefer strength-related occupations than girls. Boys were also more likely to select boys than girls as the gender who cares more about physical strength. Additionally, with age, both girls and boys demonstrated knowledge of the stereotype that boys care about physical strength, with girls also being less likely to associate being a girl with being strong. Overall, the results suggest that valuing physical strength starts in early childhood, and gender differences in valuing strength are evident at the eve of gender identity development. Possible implications for boys' later well-being and health are discussed.
Epithelioid hemangioendothelioma (EHE) is a low-grade malignant vascular neoplasm with the potential to metastasize. Primary EHE of the spine is very rare and an accurate diagnosis is crucial to treatment planning. We aim to investigate the imaging and clinical data of spinal EHE to improve the understanding of the disease.
We retrospectively analyzed the imaging manifestations and clinical data of 12 cases with pathologically confirmed spinal EHE. The imaging features analyzed included number, locations, size, border, density, signal, majority of the lesions, expansile osteolysis, residual bone trabeculae, sclerotic rim, vertebral compression, enhancement.
Patients included 5 female and 7 male patients (mean age 43.0 ± 19.6years; range 15-73years). Multiple lesions were noted in 1 case and single lesion was noted in 11 cases. The lesions were located in the thoracic, cervical, lumbar, and sacral vertebrae in 7, 3, 1, and 1 cases, respectively. They were centered in the vertebral body and posterior elements in 9 and 3 cases, respectively. Residual bone trabeculae, no sclerotic margin, and surrounding soft-tissue mass were noted in 11 cases, each, and mild expansile osteolysis and vertebral compression were noted in 10 and 6 cases, respectively. MRI was performed for 11 patients, all of whom showed isointensity on T1WI, hyperintensity or slight hyperintensity on T2WI, and hyperintensity on fat-suppressed T2WI. A marked enhancement pattern was noted in 10 cases.
Spinal EHE tend to develop in the thoracic vertebrae. EHE should be considered when residual bone trabeculae can be seen in the bone destruction area, accompanied by pathological compression fracture, no sclerotic rim, and high signal intensity for a vascular tumor on T2WI.

Alpha-fetoprotein (AFP) is related to the development of HCC. We explored if combination of IL-34 and APF could improve the diagnostic value in HBV related hepatocellular carcinoma (HBV-HCC). Serum was obtained from HBV patients or healthy control. Liver tissue was obtained from liver biopsy in CHB, HBV related cirrhosis patients or curative resection in HBV-HCC patients. Serum IL-34 and MCSF, or intrahepatic IL-34, MCSF and CD68+ tumor associate macrophages (TAMs) were determined using ELISA or immunohistochemistry. Serum IL-34 was 1.7, 1.3 or 2.3-fold higher in HBV-HCC than that of CHB, HBV related cirrhosis or healthy control, which was inhibited following trans-hepatic arterial chemoembolization (TACE) in HBV-HCC patients. Intra-hepatic IL-34 was higher in HBV-HCC than that of the other three groups. Intra-hepatic IL-34 was associated with high HBV-DNA, HBeAg-, poor differentiation and small tumor size of HBV-HCC patients. Intra-hepatic TAMs in HBV-HCC were increased 1.7 or 1.3-fold, compared to that from CHB or HBV-cirrhosis patients. Intra-hepatic TAMs were associated with high HBV-DNA, high tumor differentiation, small tumor size, abnormal AFP and more tumor number. AFP plus serum IL-34, showed the highest AUC (0.837) with sensitivity (0.632) and highest specificity (0.931), suggesting that AFP plus IL-34 enhances the reliability for prediction of the development of HBV-HCC among CHB patients. Circulating and intra-hepatic IL-34 was upregulated gradually in HBV disease progression from CHB, cirrhosis and HCC. IL-34 may be used as a diagnostic biomarker and potential therapeutic target for the management of HBV-HCC.
To investigate whetherfatty acid changes in granulosa cells (GCs) underly the pathogenic mechanisms of diminished ovarian reserve (DOR).
GCs were obtained from patients with DOR (n = 70) and normal ovarian reserve (NOR, n = 70). Analysis of fatty acids changes in GCs was then analyzed.
Patients with DOR had significantly lower levels of antral follicle count and anti-Mullerian hormone and higher levels of follicle-stimulating hormone compared with NOR patients (P < 0.001). The good-quality embryo rate was notably decreased in DOR patients (51.99 vs 39.52%, P < 0.05). A total of 15 significantly decreased fatty acids in GCs from patients with DOR. The ATP levels were markedly lower in DOR patients than in NOR patients (39.07 ± 12.89 vs 23.21 ± 13.69%, P < 0.05). Mitochondrial membrane potential decreased in DOR patients (P < 0.01). In GCs from DOR patients, the β-oxidation genes (HADHA and ACSL) and DNA repair genes (PRKDC and RAD50) were significantly downregulated (P < 0.05). Dihydroethidium molecular weight The γH2AX foci/nucleus ratio in DOR patients markedly increased relative to that of NOR patients (0.31 ± 0.03 vs 0.87 ± 0.07, P < 0.001). Meanwhile, the apoptosis rate of GCs was significantly higher in DOR patients (6.43 ± 2.11 vs 48.06 ± 6.72%, P < 0.01).
GC apoptosis resulting from the decrease of fatty acids, and associated with reduced ATP production and DNA damage, may contribute tothe pathogenic mechanisms responsible forDOR.

Adenomyosis is a poorly understood entity with no unified treatment protocol. It has been thought to only affect the quality of life of older women, but growing evidence is highlighting the increased frequency of adenomyosis in younger patients and its possible effects on fertility outcomes. This can have a great impact on how clinicians screen, diagnose, and treat this condition. The aim of this review is to explore the relationship between adenomyosis and infertility.
A literature search of the keywords "adenomyosis", "infertility", "pregnancy" and "fertility" was conducted using the PubMed and Medline search engines. The articles selected were observational, systematic reviews, meta-analyses, and randomized controlled trials. The search was limited to English, abstracts were screened, and articles were selected.
The literature reports lower clinical pregnancy rates, lower live birth rates, higher miscarriage rates, and higher odds of adverse obstetric outcomes in patients with adenomyosis. Treatment seems to be associated with higher pregnancy rates and live births rates.
