Purpose: The management of primary hyperparathyroidism (PHPT) during pregnancy may be surgical or conservative. This study compared adverse outcomes between surgical and non-surgical treatments. Additionally, the study investigated the correlation between serum calcium values and complication rates., Methods: A systematic review of retrospective studies, case series, and case reports. Biochemical parameters, interventions, and outcomes of each pregnancy were recorded. The study population comprised two groups: the non-surgical and surgical groups. Adverse outcomes were categorized as maternal, obstetric, or neonatal., Results: The surgical and non-surgical groups consisted of 163 and 185 patients, respectively. A positive correlation was observed between the mean maternal gestational calcium value and both maternal and obstetric complication. Neonatal complications were more prevalent in patients treated conservatively across all maternal calcium values (p < 0.001). No significant differences were observed in maternal outcomes and overall obstetric outcomes between the study groups, albeit a higher mean serum calcium value in the surgical group (12.3 mg/dL) compared with the non-surgical group (11.1 mg/dL)., Conclusions: Given the significantly lower neonatal adverse outcomes in the surgical group compared to the non-surgical group, along with non-inferior maternal and obstetric outcomes in the surgical group, the overall data of this study suggest that parathyroidectomy is favorable to non-surgical management even in cases of mild hypercalcemia., (© 2024.

Lymphovascular invasion (LVI) is one of the most important prognostic factors in gastric cancer as it indicates a higher likelihood of lymph node metastasis and poorer overall outcome for the patient. Despite its importance, the detection of LVI(+) in histopathology specimens of gastric cancer can be a challenging task for pathologists as invasion can be subtle and difficult to discern. Herein, we propose a deep learning-based LVI(+) detection method using H&E-stained whole-slide images. The ConViT model showed the best performance in terms of both AUROC and AURPC among the classification models (AUROC: 0.9796; AUPRC: 0.9648). The AUROC and AUPRC of YOLOX computed based on the augmented patch-level confidence score were slightly lower (AUROC: -0.0094; AUPRC: -0.0225) than those of the ConViT classification model. With weighted averaging of the patch-level confidence scores, the ensemble model exhibited the best AUROC, AUPRC, and F1 scores of 0.9880, 0.9769, and 0.9280, respectively. The proposed model is expected to contribute to precision medicine by potentially saving examination-related time and labor and reducing disagreements among pathologists.

Aims: To evaluate a simple and fast technique to ensure negative surgical margins on partial nephrectomies, while correlating margin statuses with the final pathology report., Subjects and Methods: This study was conducted for patients undergoing partial nephrectomy (PN) with T1-T2 renal tumors from January 2010 to the end of December 2015. Before tumor removal, intraoperative ultrasound (US) localization was performed. After tumor removal and before performing hemostasis of the kidney, the specimens were placed in a saline solution and a US was performed to evaluate if the tumor's capsule were intact, and then compared to the final pathology results., Results: In 177 PN(s) (147 open procedures and 30 laparoscopic procedures) were performed on 147 patients. Arterial clamping was done for 32 patients and the mean warm ischemia time was 19 ± 6 min. The mean US examination time was 41 ± 7 s. The US analysis of surgical margins was negative in 172 cases, positive in four, and in only one case it was not possible to conclude. The final pathology results revealed one false positive surgical margin and one false negative surgical margin, while all other margins were in concert with US results. The mean tumor size was 3.53 ± 1.43 cm, and the mean surgical margin was 2.8 ± 1.5 mm., Conclusions: The intraoperative US control of resection margins in PN is a simple, efficient, and effective method for ensuring negative surgical margins with a small increase in warm ischemia time and can be conducted by the operating urologist.

The ability to properly evaluate the right ventricular size and function can have important consequences for clinical management and prognosis. Echocardiography is and will remain the leading method of right ventricle (RV) assessment due to its ease of use and wealth of diagnostic information provided. Understanding the various strengths and limitations of the diverse echocardiographic methods of RV assessment can allow a systematic approach to resolve situations where one's quantitative parameters are not necessarily concordant. Quantification of RV volume can be done by two-dimensional (2D) and three-dimensional (3D) echocardiography. Measurements of RV systolic function include fractional area change (FAC), right-sided index of myocardial performance (RIMP), RV ejection fraction (RVEF), tricuspid annular plane excursion by M-Mode (TAPSE), tricuspid annular systolic longitudinal velocity by tissue Doppler (S'), and regional strain and strain rate. RVEF can also be assessed volumetrically by 3D echocardiography. This article will review the current methods used in contemporary echocardiography laboratories, with an emphasis on a guideline-based approach as well as emerging techniques.

This study describes the outcome and complications in horses that had a closed, one-stage, stapled, functional, end-to-end (COSFE) jejuno-ileal anastomosis (JIA) following resection of compromised small intestine. Medical records were reviewed to identify all horses that had a COSFE JIA performed during exploratory laparotomy and to determine post-operative complications and final outcome. All 5 horses that were identified had successful COSFE JIA with resection of various amounts of distal jejunum and proximal ileum. Post-operative ileus occurred in 1 of the 5 horses. All horses survived at least 1 year after surgery. The survival times and incidence of post-operative ileus compared favorably with published results for other types of small intestinal resection and anastomoses. A COSFE JIA is a viable surgical procedure to correct lesions of the distal jejunum and proximal ileum., This study describes the outcome and complications in horses that had a closed, one-stage, stapled, functional, end-to-end (COSFE) jejuno-ileal anastomosis (JIA) following resection of compromised small intestine.
