Abstract
JOURNAL/nrgr/04.03/01300535-202504000-00029/figure1/v/2024-07-06T104127Z/r/image-tiff Recent research has demonstrated the impact of physical activity on the prognosis of glioma patients, with evidence suggesting exercise may reduce mortality risks and aid neural regeneration. The role of the small ubiquitin-like modifier (SUMO) protein, especially post-exercise, in cancer progression, is gaining attention, as are the potential anti-cancer effects of SUMOylation. We used machine learning to create the exercise and SUMO-related gene signature (ESLRS). This signature shows how physical activity might help improve the outlook for low-grade glioma and other cancers. We demonstrated the prognostic and immunotherapeutic significance of ESLRS markers, specifically highlighting how murine double minute 2 (MDM2), a component of the ESLRS, can be targeted by nutlin-3. This underscores the intricate relationship between natural compounds such as nutlin-3 and immune regulation. Using comprehensive CRISPR screening, we validated the effects of specific ESLRS genes on low-grade glioma progression. We also revealed insights into the effectiveness of Nutlin-3a as a potent MDM2 inhibitor through molecular docking and dynamic simulation. Nutlin-3a inhibited glioma cell proliferation and activated the p53 pathway. Its efficacy decreased with MDM2 overexpression, and this was reversed by Nutlin-3a or exercise. Experiments using a low-grade glioma mouse model highlighted the effect of physical activity on oxidative stress and molecular pathway regulation. Notably, both physical exercise and Nutlin-3a administration improved physical function in mice bearing tumors derived from MDM2-overexpressing cells. These results suggest the potential for Nutlin-3a, an MDM2 inhibitor, with physical exercise as a therapeutic approach for glioma management. Our research also supports the use of natural products for therapy and sheds light on the interaction of exercise, natural products, and immune regulation in cancer treatment.

Exploring near-infrared autofluorescence properties in parathyroid tissue: an analysis of fresh and paraffin-embedded thyroidectomy specimens. JOURNAL OF BIOMEDICAL OPTICS 2025; 30:S13702. [PMID: 39034960 PMCID: PMC11256002 DOI: 10.1117/1.jbo.30.s1.s13702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Revised: 06/20/2024] [Accepted: 06/24/2024] [Indexed: 07/23/2024]
Abstract
Significance Near-infrared autofluorescence (NIRAF) utilizes the natural autofluorescence of parathyroid glands (PGs) to improve their identification during thyroid surgeries, reducing the risk of inadvertent removal and subsequent complications such as hypoparathyroidism. This study evaluates NIRAF's effectiveness in real-world surgical settings, highlighting its potential to enhance surgical outcomes and patient safety. Aim We evaluate the effectiveness of NIRAF in detecting PGs during thyroidectomy and central neck dissection and investigate autofluorescence characteristics in both fresh and paraffin-embedded tissues. Approach We included 101 patients diagnosed with papillary thyroid cancer who underwent surgeries in 2022 and 2023. We assessed NIRAF's ability to locate PGs, confirmed via parathyroid hormone assays, and involved both junior and senior surgeons. We measured the accuracy, speed, and agreement levels of each method and analyzed autofluorescence persistence and variation over 10 years, alongside the expression of calcium-sensing receptor (CaSR) and vitamin D. Results NIRAF demonstrated a sensitivity of 89.5% and a negative predictive value of 89.1%. However, its specificity and positive predictive value (PPV) were 61.2% and 62.3%, respectively, which are considered lower. The kappa statistic indicated moderate to substantial agreement (kappa = 0.478; P < 0.001 ). Senior surgeons achieved high specificity (86.2%) and PPV (85.3%), with substantial agreement (kappa = 0.847; P < 0.001 ). In contrast, junior surgeons displayed the lowest kappa statistic among the groups, indicating minimal agreement (kappa = 0.381; P < 0.001 ). Common errors in NIRAF included interference from brown fat and eschar. In addition, paraffin-embedded samples retained stable autofluorescence over 10 years, showing no significant correlation with CaSR and vitamin D levels. Conclusions NIRAF is useful for PG identification in thyroid and neck surgeries, enhancing efficiency and reducing inadvertent PG removals. The stability of autofluorescence in paraffin samples suggests its long-term viability, with false positives providing insights for further improvements in NIRAF technology.

Zhang S, Cheng T. Prognostic and clinicopathological value of systemic inflammation response index (SIRI) in patients with breast cancer: a meta-analysis. Ann Med 2024; 56:2337729. [PMID: 38569199 PMCID: PMC10993763 DOI: 10.1080/07853890.2024.2337729] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Accepted: 03/09/2024] [Indexed: 04/05/2024] Open
Abstract
BACKGROUND Many studies have explored the value of the systemic inflammation response index (SIRI) in predicting the prognosis of patients with breast cancer (BC); however, their findings remain controversial. Consequently, we performed the present meta-analysis to accurately identify the role of SIRI in predicting BC prognosis. METHODS PubMed, Embase, Cochrane Library, and Web of Science databases were comprehensively searched between their inception and February 10, 2024. The significance of SIRI in predicting overall survival (OS) and disease-free survival (DFS) in BC patients was analyzed by calculating pooled hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). RESULTS Eight articles involving 2,997 patients with BC were enrolled in the present study. According to our combined analysis, a higher SIRI was markedly associated with dismal OS (HR = 2.43, 95%CI = 1.42-4.15, p < 0.001) but not poor DFS (HR = 2.59, 95%CI = 0.81-8.24, p = 0.107) in patients with BC. Moreover, based on the pooled results, a high SIRI was significantly related to T3-T4 stage (OR = 1.73, 95%CI = 1.40-2.14, p < 0.001), N1-N3 stage (OR = 1.61, 95%CI = 1.37-1.91, p < 0.001), TNM stage III (OR = 1.63, 95%CI = 1.34-1.98, p < 0.001), and poor differentiation (OR = 1.25, 95%CI = 1.02-1.52, p = 0.028). CONCLUSION According to our results, a high SIRI significantly predicted poor OS in patients with BC. Furthermore, elevated SIRI was also remarkably related to increased tumor size and later BC tumor stage. The SIRI can serve as a novel prognostic biomarker for patients with BC.

Abstract
CONTEXT The use of traditional Chinese medicine (TCM) for breast cancer patients inhibits tumor cell growth and proliferation, alleviates adverse reactions, and inhibits tumor recurrence and metastasis post-surgery. An assessment of its historical efficacy and an examination of the latest research trends are imperative to thoroughly leverage the potential of TCM for breast cancer treatment. OBJECTIVE This study analyzes the published literature on TCM for breast cancer treatment using bibliometric analysis to determine the current state, identify hot spots, and discern trends, providing insight into research in this field. METHODS TCM-based breast cancer treatment publications between 2003 and 2022 were retrieved from the Web of Science, China National Knowledge Infrastructure, Wanfang, and Duxiu databases. Visual analysis was performed using VOSviewer (V1.6.19) and CiteSpace (V6.3.R1) software. Examined metrics included the annual publication count, literature and journal, national and institutional contributions, author co-occurrence, keyword co-occurrence, keywords timeline, and keywords with citation bursts in this research field. RESULTS AND CONCLUSION A total of 1080 English publications and 2617 Chinese publications were included in the analysis. China was the leading contributor of publications. High-frequency keywords such as 'apoptosis', 'expression', 'in vivo', 'chemotherapy', 'triple-negative breast cancer', and 'lymphedema' were identified from English and Chinese publications; 'epithelial mesenchymal transition' and 'network pharmacology' emerged as hotspots. The development of modern science, technology, and in-depth research can result in broader prospects for the research and application of TCM in breast cancer treatment, resulting in more effective solutions for the treatment of breast cancer and other malignant tumors.

Abstract
BACKGROUND Delayed gastric emptying (DGE) is one of the most common complications after pancreaticoduodenectomy (PD). DGE represents impaired gastric motility without significant mechanical obstruction and is associated with an increased length of hospital stay, increased healthcare costs, and a high readmission rate. We reviewed published studies on various technical modifications to reduce the incidence of DGE. DATA SOURCES Studies were identified by searching PubMed for relevant articles published up to December 2022. The following search terms were used: "pancreaticoduodenectomy", "pancreaticojejunostomy", "pancreaticogastrostomy", "gastric emptying", "gastroparesis" and "postoperative complications". The search was limited to English publications. Additional articles were identified by a manual search of references from key articles. RESULTS In recent years, various surgical procedures and techniques have been explored to reduce the incidence of DGE. Pyloric resection, Billroth II reconstruction, Braun's enteroenterostomy, and antecolic reconstruction may be associated with a decreased incidence of DGE, but more high-powered studies are needed in the future. Neither laparoscopic nor robotic surgery has demonstrated superiority in preventing DGE, and the use of staplers is controversial regarding whether they can reduce the incidence of DGE. CONCLUSIONS Despite many innovations in surgical techniques, there is no surgical procedure that is superior to others to reduce DGE. Further larger prospective randomized studies are needed.

Abstract
BACKGROUND Pancreaticoduodenectomy is the standard treatment for resectable periampullary cancer. Surgical site infections (SSI) are common complications with increased morbidity. The study aimed to describe the prevalence, risk factors, microbiology, and outcomes of SSI among patients undergoing pancreaticoduodenectomy. METHODS We conducted a retrospective study in a referral cancer center between January 2015 and June 2021. We analyzed baseline patient characteristics and SSI occurrence. Culture results and susceptibility patterns were described. Multivariate logistic regression was used to determine risk factors, proportional hazards model to evaluate mortality, and Kaplan-Meier analysis to assess long-term survival. RESULTS A total of 219 patients were enrolled in the study; 101 (46%) developed SSI. Independent factors for SSI were diabetes mellitus, preoperative albumin level, biliary drainage, biliary prostheses, and clinically relevant postoperative pancreatic fistula. The main pathogens were Enterobacteria and Enterococci. Multidrug-resistance rate in SSI was high but not associated with increased mortality. Infected patients had higher odds of sepsis, longer hospital stay and intensive care unit stay, and readmission rate. Neither 30-day mortality nor long-term survival was significantly different between infected and non-infected patients. CONCLUSIONS SSI prevalence among patients undergoing pancreaticoduodenectomy was high and largely caused by resistant microorganisms. Most risk factors were related to preoperative instrumentation of the biliary tree. SSI was associated with greater risk of unfavorable outcomes; however, survival was unaffected.

Incidence and severity of acute radiation induced toxicities among breast cancer patients treated with adjuvant radiotherapy at a major cancer treatment center in Ghana. Transl Oncol 2024; 47:102032. [PMID: 38945020 DOI: 10.1016/j.tranon.2024.102032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 06/03/2024] [Accepted: 06/10/2024] [Indexed: 07/02/2024] Open
Abstract
BACKGROUND Adjuvant radiotherapy after mastectomy or breast conserving surgery (BCS) is the standard of care for majority of patients with breast cancer. This is however associated with mucosal and epidermal toxicity of organs at risk (OARs). Breast cancer patients are exposed to a plethora of wrong perceptions, misinformation and myths concerning the usefulness and adverse effects of radiotherapy. There is paucity of literature on the incidence and severity of radiation-induced acute toxicities experienced by patients with breast cancer in Ghana. AIM To assess the occurrence and severity of four main acute radiation-induced toxicities among female breast cancer patients treated with external beam radiotherapy at a major cancer treatment centre in Ghana. METHODS Data on the occurrence of acute toxicities among patients was collected from patients' medical records, through a semi-structured questionnaire and via weekly clinical assessments. The Common Terminology Criteria for Adverse Events (CTCAE) grading scale (version 4.0) was used to grade the severity of these toxicities. Descriptive and inferential statistics using an independent two-sampled t-test (two-tailed), one-way analysis of variance (ANOVA), Pearson's Chi-square and Fisher's exact tests were performed. RESULTS Dermatitis, fatigue, pharyngitis, and breast (chest) pain were the radiation toxicities found among the breast cancer patients undergoing treatment on the two machines. The mean predominant radiation doses associated with the onset of dermatitis, fatigue, pharyngitis, and chest pain in the breast cancer patients were 22.32 Gy, 22.48 Gy, 13.59 Gy, and 19.27 Gy respectively for treatment with a statistically significant (p = 0.0173). Radiation dermatitis was the most dominant acute radiation toxicity recorded, and its incidence and severity. The range of Fisher's p-values (0.689-0.999) between the acute radiation toxicities with both machines revealed no statistical significance. CONCLUSION Radiation dermatitis was the dominant acute toxicity, both in incidence and severity for patients treated. There was no statistical significance in the incidence and severity of acute radiation side effects.

Abstract
BACKGROUND Progesterone receptor (PR) serves as a crucial prognostic and predictive marker in breast cancer. Nonetheless, the interplay between PR and the tumor immune microenvironment remains inadequately understood. This investigation employs bioinformatics analyses, mouse models, and clinical specimens to elucidate the impact of PR on immune microenvironment and identify potential targets for immunotherapy, furnishing valuable guidance for clinical practice. METHODS Analysis of immune infiltration score by Xcell between PR-positive and PR-negative breast cancer tumors. Construction of overexpression mouse progesterone receptor (mPgr) EMT-6 cell was to explore the tumor immune microenvironment. Furthermore, anti- Lymphocyte-activation gene 3 (LAG3) therapy aimed to investigate whether PR could influence the effectiveness of immune treatments. RESULTS Overexpression mPgr inhibited tumor growth in vitro, but promoted tumor growth in Balb/c mouse. Flow cytometry showed that the proportion and cytotoxicity of CD8+T cells in tumor of overexpressing mPgr group were significantly reduced. The significant reduction in overexpressing mPgr group was found in the proportions of LAG3+CD8+ T cells and LAG3+ Treg T cells. Anti-LAG3 treatment resulted in reduced tumor growth in EV group mouse rather than in overexpressing mPgr group. Patents derived tumor fragment (PDTF) also showed higher anti-tumor ability of CD3+T cell in patents' tumor with PR <20% after anti-human LAG3 treatment in vitro. CONCLUSIONS The mPgr promotes tumor growth by downregulating the infiltration and function of cytotoxic cell. LAG3 may be a target of ER-positive breast cancer immunotherapy. The high expression of PR hinders the sensitivity to anti-LAG3 treatment.

Construction of ceRNA network mediated by circRNAs screening from microarray and identification of novel biomarkers for myasthenia gravis. Gene 2024; 918:148463. [PMID: 38631652 DOI: 10.1016/j.gene.2024.148463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 04/03/2024] [Accepted: 04/10/2024] [Indexed: 04/19/2024]
Abstract
BACKGROUND Recent studies have revealed that circRNA can serve as ceRNA to participate in multiple autoimmune diseases. Our study aims to explore the key circRNA as ceRNA and biomarker for MG. METHODS We used circRNA microarray to explore differentially expressed circRNAs (DECs) from MG and compare with control. Then, we predicted the target miRNA associated with DECs and screened miRNAs by the algorithm of random walk with restart (RWR). Next, we constructed the circRNA-miRNA-mRNA ceRNA regulated network (CMMC) to identify the hub objects. Following, we detected the expression of hub-circRNAs by RT-PCR. We verify has_circ_0004183 (circFRMD4) sponging miR-145-5p regulate cells proliferation using luciferase assay and CCK-8. RESULTS We found that the expression level of circFRMD4 and has_circ_0035381 (circPIGB) were upregulated and has_circ_0089153(circ NUP214) had the lowest expression level in MG. Finally, we proved circFRMD4 sponging miR-145-5p regulate Jurkat cells proliferation. CircFRMD4 take part in the genesis and development of MG via circFRMD4/miR145-5p axis. CONCLUSIONS We found that circFRMD4, circPIGB and circNUP214 can be considered as valuable potential novel biomarkers for AchR + MG. CircFRMD4 participate in the development of AchR + MG via targeting binding with miR-145-5p.

Abstract
BACKGROUND Multiple medications are more effective than single agents for postoperative pain management. We investigated the analgesic effects of an intravenous combination of acetaminophen and ibuprofen immediately after thyroidectomy. METHODS In this double-blind clinical trial, 62 patients who underwent thyroidectomies were randomized to either the treatment (1000 mg acetaminophen, 300 mg ibuprofen) or control (1000 mg acetaminophen) group. Postoperative pain intensity was assessed using the visual analog scale (VAS) 0, 15, and 30 min after recovery room admission. Opioid rescue consumption was also recorded. RESULTS The VAS scores were significantly lower in the treatment than in the control group 15 [3 (2-4.3) vs. 5 (3-6); p = 0.015] and 30 [3 (2-4.3) vs. 4 (3-5); p = 0.018] min after recovery room admission, as were the opioid rescue dose requirements (p = 0.033). CONCLUSIONS Combined intravenous acetaminophen and ibuprofen may be better than acetaminophen alone for immediately acute postoperative pain after thyroidectomy.

Abstract
INTRODUCTION Recurrent laryngeal nerve (RNL) identification constitutes the standard in thyroidectomy. Intraoperative nerve monitoring (IONM) has been introduced as a complementary tool for RLN functionality evaluation. The aim of this study is to establish how routine use of IONM can affect the learning curve (LC) in thyroidectomy. METHODS Patients undergoing total thyroidectomy performed by surgery residents in their learning curve course in 2 academic hospitals, were divided into 2 groups: Group A, including 150 thyroidectomies performed without IONM by 3 different residents, and Group B, including 150 procedures with routine use of intermittent IONM, by other 3 different residents. LC was measured by comparing operative time (OT), its stabilization during the development of the LC, perioperative complication rate. RESULTS As previously demonstrated, the LC was achieved after 30 procedures, in both groups, with no differences due to the use of IONM. Similarly, there were no significant differences among the 2 groups, and between subgroups independently matched, for both OT and complications, even when comparing RLN palsy. Direct nerve visualization and IONM assessment rates were comparable in all groups, and no bilateral RLN palsy (transient or permanent) were reported. No case of interrupted procedure to unilateral lobectomy, due to evidence of RLN injury, was reported. CONCLUSIONS The study demonstrates that the use of IONM thyroid surgery, despite requiring a specific training with experienced surgeons, does not particularly affect the learning curve of residents approaching this kind of surgery, and for this reason its routine use should be encouraged even for trainees.

Abstract
Sutureless anastomotic devices present several advantages over traditional suture anastomosis, including expanded global access to microvascular surgery, shorter operation and ischemic times, and reduced costs. However, their adaptation for arterial use remains a challenge. This review aims to provide a comprehensive overview of sutureless anastomotic approaches that are either FDA-approved or under investigation. These approaches include extraluminal couplers, intraluminal devices, and methods assisted by lasers or vacuums, with a particular emphasis on tissue adhesives. We analyze these devices for artery compatibility, material composition, potential for intimal damage, risks of thrombosis and restenosis, and complications arising from their deployment and maintenance. Additionally, we discuss the challenges faced in the development and clinical application of sutureless anastomotic techniques. Ideally, a sutureless anastomotic device or technique should eliminate the need for vessel eversion, mitigate thrombosis through either biodegradation or the release of antithrombotic drugs, and be easily deployable for broad use. The transformative potential of sutureless anastomotic approaches in microvascular surgery highlights the necessity for ongoing innovation to expand their applications and maximize their benefits.

Abstract
OBJECTIVE Static 3-dimensional (3D) printing became attractive for operative planning in cases that involve difficult anatomy. An interactive (low cost, fast) 3D print allowing deliberate surgical practice can be used to improve interventional simulation and planning. BACKGROUND Endovascular treatment of complex aortic aneurysms is technically challenging, especially in case of narrow aortic lumen or significant aortic angulation (hostile anatomy). The risk of complications such as graft kinking and target vessel occlusion is difficult to assess based solely on traditional software measuring methods and remain highly dependent on surgeon skills and expertise. METHODS A patient with juxtarenal AAA with hostile anatomy had a 3-dimensional printed model constructed preoperatively according to computed tomography images. Endovascular graft implantation in the 3D printed aorta with a standard T-Branch Cook (Cook® Medical, Bloomington, IN, USA) was performed preoperatively in the simulation laboratory enabling optimized feasibility, surgical planning and intraoperative decision making. RESULTS The 3D printed aortic model proved to be radio-opaque and allowed simulation of branched endovascular aortic repair (BREVAR). The assessment of intervention feasibility, as well as optimal branch position and orientation was found to be useful for surgeon confidence and the actual intervention in the patient. There was a remarkable agreement between the 3D printed model and both CT and X-ray angiographic images. Although the technical success was achieved as planned, a previously deployed renal stent caused unexpected difficulty in advancing the renal stent, which was not observed in the 3D model simulation. CONCLUSION The 3D printed aortic models can be useful for determining feasibility, optimizing planning and intraoperative decision making in hostile anatomy improving the outcome. Despite already offering satisfying accuracy at present, further advancements could enhance the 3D model capability to replicate minor anatomical deformities and variations in tissue density.

Abstract
Pheochromocytomas and paragangliomas are distinctive neuroendocrine tumors which frequently produce excess catecholamines with resultant cardiovascular morbidity. These tumors have a strong genetic component, with up to 40% linked to hereditary pathogenic variants; therefore, germline genetic testing is recommended for all patients. Surgical resection offers the only potential cure in the case of localized disease. Given the potential for catecholaminergic crises, appropriate perioperative management is crucial, and all patients should undergo alpha-adrenergic blockade before resection. Therapeutic options for metastatic disease are limited and include surgical debulking, radiopharmaceutical therapies, and conventional chemotherapy.

Abstract
BACKGROUND Direct-to-implant (DTI) reconstruction has multiple advantages over a staged tissue expander (TE) approach. However, its use may be limited by concerns of increased complications. This study is the largest series to date comparing postoperative outcomes for DTI versus TE reconstruction in the prepectoral plane. METHODS The authors retrospectively reviewed 348 patients who underwent 536 total immediate, prepectoral implant-based breast reconstructions between January of 2018 and December of 2021. The authors compared the presence of risk factors and the rate of six separate complications between patients who underwent DTI versus TE reconstruction up to 1 year after surgery. RESULTS Of 348 patients, 147 (42%) and 201 (58%) underwent TE and DTI reconstruction ( P = 0.1813), respectively. The overall infection rate was 16.4% ( n = 57). DTI patients had a significantly greater incidence of wounds ( P < 0.0001), including minor ( P < 0.0011) and major wounds ( P < 0.0053). Significantly greater mastectomy resection weights were found for DTI patients who experienced any complication ( P < 0.0076), postoperative wounds ( P < 0.0001), and major wounds specifically ( P < 0.0035). Compared with medium-thickness acellular dermal matrix (ADM), extra thick ADM was associated with significantly increased rates of infection ( P < 0.0408) and wounds ( P < 0.0001). CONCLUSIONS Prepectoral DTI reconstruction in patients with adequate flap perfusion may have complication rates comparable to staged TE reconstruction, apart from a higher incidence of postoperative wounds. Greater mastectomy resection weights and thickness of ADM may specifically contribute to infection and wound-healing complications. Prepectoral DTI reconstruction is encouraged in the patients with adequate flap perfusion and moderate to low mastectomy resection weights who desire comparable or smaller implant volumes.

Abstract
PURPOSE Thyroid cancer incidence has increased in recent decades, and thyroid surgery is continuously evolving in response to demands for postoperative comfort and cosmesis. This study aimed to introduce a new surgical method for minimally invasive open bilateral total thyroidectomy (MI-BTT) using a unilateral 2.5-3.0 cm neck incision. Furthermore, we reported the surgical outcomes and postoperative quality of life (QoL) using a validated Korean translated Dermatology Life Quality Index (DLQI) questionnaire. MATERIALS AND METHODS We retrospectively evaluated 41 Asian patients who underwent MI-BTT for low-risk papillary thyroid cancer by a single surgeon from March 2019 to December 2021. RESULTS A total of 4 male and 37 female patients were included. The mean age and body mass index were 46.2±10.1 years and 23.3±3.3 kg/m², respectively. The average tumor size was 1.1±0.6 cm, and 36 patients (87.8%) had bilateral cancer. Twenty-three (56.1%) patients had occult central lymph node (CLN) metastasis in the final pathologic report, with the mean number of dissected CLNs being 7.2±6.5. Gross capsular extension was found in 6 patients (14.6%). Moreover, 28 patients (68.3%) received additional treatment after surgery with low or high doses of radioactive iodine. The average serum-stimulated thyroglobulin value identified during treatment was 1.57±2.30 ng/mL. The mean operation time was 78.0±13.9 minutes, and postoperative complications included transient hypocalcemia (36.6%), transient hoarseness (24.4%), and seroma (2.4%). The mean total DLQI score was 2.73±0.78, indicating a small effect on QoL. CONCLUSION MI-BTT is a novel, safe, and feasible technique to improve patient satisfaction for surgical scars and QoL.

Abstract
Thyroid nodules are widely prevalent, and often discovered incidentally. Malignancy rates are low for incidental thyroid nodules, and overall outcomes are favorable regardless of diagnosis. Patients with thyroid nodules should be evaluated with TSH levels followed by ultrasound of the thyroid and cervical lymph nodes. It is important to recognize sonographic features suspicious for thyroid malignancy and obtain biopsies when indicated according to major society guidelines. The Bethesda System for Reporting Thyroid Cytopathology along with molecular testing can help guide management decisions regarding thyroid nodules. Surgical resection and other emerging technologies are safe and effective for the treatment of thyroid nodules needing intervention.

Abstract
PURPOSE In the present study, we addressed the inconsistency between the testing criteria and diverse phenotypes for germline TP53 mutation in patients with breast cancer in the Chinese population. METHOD We proposed a new added item (synchronous or metachronous bilateral breast cancer) as one of the testing criteria (aimed at high-penetrance breast cancer susceptibility genes) and applied it for determining TP53 germline mutation status in 420 female patients with breast cancer using multigene panel-based next-generation sequencing, Sanger sequencing, and mass spectrometry. RESULTS We found that 1.4% of patients carried a pathogenic or likely pathogenic germline TP53 mutation. Compared with BRCA mutation carriers (8.0%) and non-carriers (7.1%), TP53 mutation carriers (33.3%) developed breast cancer earlier. The majority of TP53 mutation carriers (66.7%) developed breast cancer after age 30 and had bilateral breast cancer (33.3%). Pedigree investigation of four TP53 carriers and a patient with a TP53 variant of unknown significance revealed that neither of their parents harbored the same mutations as the probands, indicating that the mutations might occur de novo. CONCLUSION Our study revealed distinguishing features of TP53 carriers among Chinese women with breast cancer, which is inconsistent with the currently used testing criteria; therefore, the newly proposed testing criteria may be more appropriate.

Abstract
BACKGROUND Breast cancer survival rates have increased significantly, underscoring the importance of enhancing long-term health-related quality of life. Breast reconstruction following mastectomy has emerged as a common approach that contributes to improved health-related quality of life. Nonetheless, chronic pain following breast reconstruction is a prevalent issue that has a negative impact on overall well-being. METHODS To examine recent findings on chronic pain after breast reconstruction and progress in pain management, we performed a review of the literature through independent searches using the MEDLINE database within NIH National Library of Medicine PubMed. RESULTS The review suggested that autologous reconstruction causes chronic postsurgical pain, especially at specific donor sites, whereas implant-based reconstruction does not seem to increase the risk of chronic pain. Moreover, certain operational and patient factors are also associated with chronic pain. Appropriate pain management can reduce chronic pain and prevent the transition from acute to chronic pain. CONCLUSION This scoping review evaluated the characteristics of long-term chronic pain after breast reconstruction. The findings provide patients with important treatment information and will assist with their decision on their preferred treatment.

ULTRASOUND IN MEDICINE & BIOLOGY 2024; 50:1183-1187. [PMID: 38704301 DOI: 10.1016/j.ultrasmedbio.2024.04.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/16/2024] [Revised: 03/23/2024] [Accepted: 04/10/2024] [Indexed: 05/06/2024]
Abstract
OBJECTIVE The aim of the work described here was to explore the predictive value of multimodal ultrasound combined with the BRAF gene in cervical lymph node metastasis (CLNM) of papillary thyroid microcarcinoma (PTMC). METHODS One hundred six patients (114 lesions) with PTMC confirmed by surgery and pathology at Yantai Yuhuangding Hospital from July 2021 to August 2022 were analyzed retrospectively. Routine ultrasound, contrast-enhanced ultrasound, shear wave elastography examination and BRAF V600E gene detection were performed before surgery. Patients were divided into two groups on the basis of post-operative pathology: non-metastasis group and metastasis group. Univariate and multivariate analyses were used to analyze the risk factors of cervical lymph node metastasis in PTMC. RESULTS Univariate analysis revealed that there were significant differences in gender, high echo in lesions, enhancement level, peak intensity (PI) and average modulus of elasticity (Eavg) between the two groups (p < 0.05), but there was no significant difference in BRAF gene mutation (p = 0.855). Multivariate analysis revealed that male gender, microcalcification and hyper- or iso-enhancing parametric increased the risk of CLNM in PTMC (p < 0.05), and that sensitivity (92.3%) and accuracy (73.9%) were higher for combined diagnosis than for single diagnosis; the differences were statistically significant (p < 0.05). CONCLUSION Male gender, microcalcification and hyper- or iso-enhancing parametrics of CEUS are independent risk factors for CLNM in PTMC patients. Combined diagnosis is more effective.

Prediction of human epidermal growth factor receptor 2 (HER2) status in breast cancer by mammographic radiomics features and clinical characteristics: a multicenter study. Eur Radiol 2024; 34:5464-5476. [PMID: 38276982 DOI: 10.1007/s00330-024-10607-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 12/11/2023] [Accepted: 12/23/2023] [Indexed: 01/27/2024]
Abstract
OBJECTIVES To preoperatively evaluate the human epidermal growth factor 2 (HER2) status in breast cancer using mammographic radiomics features and clinical characteristics on a multi-vendor and multi-center basis. METHODS This multi-center study included a cohort of 1512 Chinese female with invasive ductal carcinoma of no special type (IDC-NST) from two different hospitals and five devices (1332 from Institution A, used for training and testing the models, and 180 women from Institution B, as the external validation cohort). The Gradient Boosting Machine (GBM) was employed to establish radiomics and multiomics models. Model efficacy was evaluated by the area under the curve (AUC). RESULTS The number of HER2-positive patients in the training, testing, and external validation cohort were 245(26.3%), 105 (26.3.8%), and 51(28.3%), respectively, with no statistical differences among the three cohorts (p = 0.842, chi-square test). The radiomics model, based solely on the radiomics features, achieved an AUC of 0.814 (95% CI, 0.784-0.844) in the training cohort, 0.776 (95% CI, 0.727-0.825) in the testing cohort, and 0.702 (95% CI, 0.614-0.790) in the external validation cohort. The multiomics model, incorporated radiomics features with clinical characteristics, consistently outperformed the radiomics model with AUC values of 0.838 (95% CI, 0.810-0.866) in the training cohort, 0.788 (95% CI, 0.741-0.835) in the testing cohort, and 0.722 (95% CI, 0.637-0.811) in the external validation cohort. CONCLUSIONS Our study demonstrates that a model based on radiomics features and clinical characteristics has the potential to accurately predict HER2 status of breast cancer patients across multiple devices and centers. CLINICAL RELEVANCE STATEMENT By predicting the HER2 status of breast cancer reliably, the presented model built upon radiomics features and clinical characteristics on a multi-vendor and multi-center basis can help in bolstering the model's applicability and generalizability in real-world clinical scenarios. KEY POINTS • The mammographic presentation of breast cancer is closely associated with the status of human epidermal growth factor receptor 2 (HER2). • The radiomics model, based solely on radiomics features, exhibits sub-optimal performance in the external validation cohort. • By combining radiomics features and clinical characteristics, the multiomics model can improve the prediction ability in external data.

Abstract
BACKGROUND Partial or total laryngopharyngectomy defects have traditionally been reconstructed using the radial forearm, anterolateral thigh, or jejunal free flaps. The latissimus dorsi myocutaneous free flap (LDMFF) is an option for high-risk patients with complex laryngopharyngeal ± cutaneous neck defects. METHODS Retrospective single-surgeon case series from 2017 to 2022. Outcomes were assessed at both the back donor site and head and neck. RESULTS Twenty-four patients were identified. Flap survival was 100%. There was 1 (4.2%) pharyngocutaneous fistula and 2 (8.3%) tracheo-esophageal peristomal fistulas. At last follow-up, 17 (71%) were sustaining weight on oral intake, and 7 (29%) were G-tube dependent with 4 of these able to do some type of oral intake. Seven (29.2%) had post-operative stricture/stenosis requiring dilation. There were only minor donor site complications, all managed conservatively. CONCLUSIONS The LDMFF can be a robust reconstructive option, particularly for radiated high-risk patients with complex pharyngeal defects, including skin.

Abstract
BACKGROUND AND OBJECTIVES Sentinel lymph node (SLN) biopsy is a standard procedure for patients with breast cancer and normal axilla on imaging. Positive SLNs on histological examination can lead to a subsequent surgery for axillary lymph node clearance (ALNC). Here we report a non-destructive technique based on autofluorescence (AF) imaging and Raman spectroscopy for intra-operative assessment of SLNs excised in breast cancer surgery. METHODS A microscope integrating AF imaging and Raman spectroscopy modules was built to allow scanning of lymph node biopsy samples. During AF-Raman measurements, AF imaging determined optimal sampling locations for Raman spectroscopy measurements. After optimisation of the AF image analysis and training of classification models based on data from 85 samples, the AF-Raman technique was tested on an independent set of 81 lymph nodes comprising 58 fixed and 23 fresh specimens. The sensitivity and specificity of AF-Raman were calculated using post-operative histology as a standard of reference. RESULTS The independent test set contained 66 negative lymph nodes and 15 positive lymph nodes according to the reference standard, collected from 78 patients. For this set of specimens, the area under the receiver operating characteristic (ROC) curve for the AF-Raman technique was 0.93 [0.83-0.98]. AF-Raman was then operated in a regime that maximised detection specificity, producing a 94% detection accuracy: 80% sensitivity and 97% specificity. The main confounders for SLN metastasis were areas rich in histiocytes clusters, for which only few Raman spectra had been included in the training dataset. DISCUSSION This preliminary study indicates that with further development and extension of the training dataset by inclusion of additional Raman spectra of histiocytes clusters and capsule, the AF-Raman may become a promising technique for intra-operative assessment of SLNs. Intra-operative detection of positive biopsies could avoid second surgery for axillary clearance.

Abstract
BACKGROUND Many adrenal tumors are deemed radiologically indeterminate and surgically removed. Adrenal tissue, like parathyroid glands, exhibits near-infrared autofluorescence (NIRAF) properties. This study was designed to investigate the potential of NIRAF to differentiate benign versus malignant adrenal tumors. METHODS Patients undergoing adrenalectomy between October 2021 and May 2023 were prospectively studied. Adrenalectomy specimens were inspected with NIRAF imaging. Specimen autofluorescence (AF) characteristics were recorded. Comparisons were made between different tumor types and a logistic regression model was constructed to differentiate benign versus malignant tumors. A receiver operating characteristic curve was used to identify an optimal AF threshold differentiating benign versus malignant tumors. RESULTS A total of 108 adrenal specimens were examined: adrenocortical adenomas/other benign lesions (n = 72), pheochromocytomas (n = 18), adrenocortical neoplasms of uncertain behavior (n = 4), and malignant tumors (n = 14). A significant difference in normalized AF intensity was identified when comparing adrenocortical adenomas (3.08 times background) with pheochromocytomas (1.95, p = 0.001) and malignant tumors (1.11, p < 0.0001). The Area Under the Curve differentiating benign vs malignant tumors was 0.87, with an optimal normalized AF threshold at 1.93. CONCLUSIONS Different adrenal pathologies exhibit diverse AF properties. These findings suggest a potential intraoperative utility of NIRAF in predicting benign versus malignant nature for radiologically indeterminate adrenal tumors.

Abstract
BACKGROUND Conventional open thyroidectomy (COT) remains a common method of thyroidectomy in many parts of the world for various reasons. METHODS In this prospective (cross-sectional) study, we evaluated the scar satisfaction among patients and surgeons following COT using the Patient and Observer Scar Assessment Scale (POSAS) and the Patient Scar Assessment Questionnaire (PSAQ). RESULTS A total of 116 patients were included. The median age of the patients was 44 years and the majority were women. The median scar length overall was 12.2 cm. On POSAS, the median score for surgeon 1 was 1 (range 1-5), for surgeon 2, it was 2 (range 1-6), and for the patient, it was 1 (range 1-6) suggesting good scar satisfaction. The patient's response in the PSAQ was also echoing similar outcomes with scar satisfaction. CONCLUSIONS Overall, both the patients and the surgeons seem to be satisfied with the overall scar appearance following COT despite the scar length.

Abstract
PURPOSE The skin and/or nipple-sparing approach has become an oncologically sound and desirable choice for women choosing mastectomy. Indocyanine green (ICG) perfusion imaging has been shown to reduce ischemic complications in mastectomy skin flaps. Immediate reconstruction requires a well-vascularized skin flap capable of tolerating full expansion. Identification of the perforating subcutaneous vessels to the skin envelope may allow for better and more consistent blood vessel preservation and flap perfusion. METHODS The authors conducted an institutional review board-approved prospective study with 41 patients to assess the feasibility of using ICG perfusion imaging to visualize, cutaneously map, and preserve the vessels that supply the skin flap and nipple-areolar complex. For each patient, the number of vessels initially mapped, the number of vessels preserved, the extent to which each vessel was preserved, and the proportion of the flap with adequate perfusion (as defined by the SPY-Q > 20% threshold) was recorded and analyzed. RESULTS Vessels were able to be identified and marked in a high majority of patients (90%). There was a moderate linear relationship between the number of vessels marked and the number preserved. Successful mapping of vessels was associated with lower rates of wound breakdown (p = 0.036). Mapping and preserving at least one vessel led to excellent flap perfusion (> 90%). No increase in complications was observed from utilizing ICG angiography preoperatively. CONCLUSION This prospective study using preoperative ICG perfusion mapping demonstrated safety, feasibility, and good prognostic outcomes. LEVEL OF EVIDENCE III.

Abstract
Primary hyperparathyroidism (PHPT) is caused by the overproduction of parathyroid hormone by 1 or more parathyroid glands resulting in hypercalcemia and its downstream clinical consequences. The definitive management of PHPT is surgery. Approaches to successful surgery include bilateral exploration or focused parathyroidectomy with intraoperative parathyroid hormone monitoring, which in experienced hands are both associated with a low risk of complications.

Abstract
BACKGROUND Nipple-sparing mastectomy (NSM) is an oncologically safe approach for breast cancer treatment and prevention; however, there are little long-term data to guide management for patients whose nipple margins contain tumor or atypia. METHODS NSM patients with tumor or atypia in their nipple margin were identified from a prospectively maintained, single-institution database of consecutive NSMs. Patient and tumor characteristics, treatment, recurrence, and survival data were assessed. RESULTS A total of 3158 NSMs were performed from June 2007 to August 2019. Nipple margins contained tumor in 117 (3.7%) NSMs and atypia only in 164 (5.2%) NSMs. Among 117 nipple margins that contained tumor, 34 (29%) margins contained invasive cancer, 80 (68%) contained ductal carcinoma in situ only, and 3 (3%) contained lymphatic vessel invasion only. Management included nipple-only excision in 67 (57%) breasts, nipple-areola complex excision in 35 (30%) breasts, and no excision in 15 (13%) breasts. Only 23 (24%) excised nipples contained residual tumor. At 67 months median follow-up, there were 2 (1.8%) recurrences in areolar or peri-areolar skin, both in patients with nipple-only excision. Among 164 nipple margins containing only atypia, 154 (94%) nipples were retained. At 60 months median follow-up, no patient with atypia alone had a nipple or areola recurrence. CONCLUSIONS Nipple excision is effective management for nipple margins containing tumor. No intervention is required for nipple margins containing only atypia. Our results support broad eligibility for NSM with careful nipple margin assessment.

Abstract
BACKGROUND This study presents preliminary results of robot-assisted nipple-sparing immediate breast reconstruction (R-NSMIBR) with gel implant combined with latissimus dorsi muscle flap without island flap and validation of the safety and utility of this novel surgical modality. METHODS Records pertinent to R-NSMIBR with gel implants combined with latissimus dorsi muscle flap surgery for breast reconstruction between September 2022 and May 2023 were examined. A total of 13 patients who underwent R-NSMIBR were analyzed, nine of which were performed without skin island. RESULTS We divided the patients with and without skin islands into two groups and recorded the operation time and bleeding respectively. The mean total operative time for R-NSMIBR was 436.5±56.88 minutes and 355.75±69.68 minutes. As experience in learning increased, time required to create the operating space and position the robotic arm decreased significantly. Not creating an island of skin also saves a great deal of surgical time. Average total blood loss was 37.5±6.45 mL and 26.25±7.5 mL. No cases of nipple-areolar complex necrosis or perioperative complications or no local recurrences were reported. There were no local recurrences or deaths that occurred during a mean follow-up period of 3±1 months. CONCLUSIONS All the patients expressed satisfaction with the aesthetic outcome following surgery. There were no significant differences between two groups. This surgical method shows promise for future promotion in the field.

Abstract
OBJECTIVE We investigated motivation levels across the general Brazilian population and subgroups and their willingness to spend for surgery without a cervical scar. METHODS This random-sample survey was performed by a specialized third-party research institute. In this study, we created a hypothetical thyroidectomy scenario, and the transcervical and transoral endoscopic thyroidectomy vestibular approach (TOETVA) were used. The survey included sociocultural data and questions regarding participants' surgical preferences. RESULTS Data were obtained from 1250 participants; 42.4% were of the opinion that a cervical scar affects social or professional life. Young and childless women were most likely to be affected (p <0.001). All respondents accepted the transoral approach to avoid cervical scarring. However, 30.7% and 31.9% of respondents maintained their preference for TOETVA despite understanding the risks of a hypothetical increase in complications and unfavorable oncological outcomes and 98.6% were of the opinion that this approach was likely associated with greater postoperative pain. Only 16.2% were unwilling to spend for TOETVA. The variable that most affected patients' willingness to spend was a salary greater than 10 Brazilian minimum wages (odds ratio 9.797, 95% confidence interval, p <0.005). Upper class respondents were 10 times more likely to spend for TOETVA than lower class patients. CONCLUSION This study highlights patients' interest in TOETVA. Cervical scar perception is affected by concerned about appearance, particularly in certain societal subgroups. Our study population showed significant motivation to undergo TOETVA, which was emphasized by their acceptance of the complication rate, poor postoperative outcomes, greater postoperative pain, and willingness to spend on surgery with an invisible scar.

Abstract
BACKGROUND Machine learning (ML) is a form of artificial intelligence that has been used to create better predictive models in medicine. Using ML algorithms, we sought to create a predictive model for breast resection weight based on anthropometric measurements. METHODS We analyzed 237 patients (474 individual breasts) who underwent reduction mammoplasty at our institution. Anthropometric variables included body surface area (BSA), body mass index, sternal notch-to-nipple (SN-N), and nipple-to-inframammary fold values. Four different ML algorithms (linear regression, ridge regression, support vector regression, and random forest regression) either including or excluding the Schnur Scale prediction for the same data were trained and tested on their ability to recognize the relationship between the anthropometric variables and total resection weights. Resection weight prediction accuracy for each model and the Schnur scale alone were evaluated based on using mean absolute error (MAE). RESULTS In our cohort, mean age was 40.36 years. Most patients (71.61%) were African American. Mean BSA was 2.0 m 2 , mean body mass index was 33.045 kg/m 2 , mean SN-N was 35.0 cm, and mean nipple-to-inframammary fold was 16.0 cm. Mean SN-N was found to have the greatest variable importance. All 4 models made resection weight predictions with MAE lower than that of the Schnur Scale alone in both the training and testing datasets. Overall, the random forest regression model without Schnur scale weight had the lowest MAE at 186.20. CONCLUSION Our ML resection weight prediction model represents an accurate and promising alternative to the Schnur Scale in the setting of reduction mammaplasty consultations.

Abstract
BACKGROUND Hybrid breast reconstruction combines free tissue transfer with implant placement. Various mesh products have been successfully used to secure the implant position in these reconstructions. In this study, the authors investigate the impact of mesh type on long-term outcomes following hybrid breast reconstruction. METHODS A retrospective analysis of all patients with at least 24 months of follow-up after immediate bilateral prepectoral hybrid breast reconstruction was performed. Univariate and multivariable regression analyses were used to evaluate long-term outcomes and compare breasts reconstructed with polyglactin mesh versus acellular dermal matrix (ADM). RESULTS Thirty-nine patients (78 breasts) who underwent hybrid breast reconstruction with an average follow-up period of 50.4 months (range, 27 to 73 months) were included in the study. Postoperative complications included hematoma ( n = 2 [2.6%]), mastectomy skin necrosis ( n = 12 [15.4%]), and fat necrosis ( n = 6 [7.7%]). There were no instances of implant infection, implant exposure, or flap failure. Polyglactin mesh and ADM were used in 24 breasts and 54 breasts, respectively. Implant malposition and capsular contracture occurred more frequently in the polyglactin cohort leading to 10 (41.7%) instances of reoperation for implant replacement compared with only 1 (1.9%) in the ADM cohort ( P < 0.001). On multivariable regression analysis, polyglactin mesh was associated with a 36-fold greater probability of requiring implant replacement compared with ADM ( P = 0.006). CONCLUSION ADM (versus polyglactin mesh) is associated with lower rates of capsular contracture and implant malposition in the context of hybrid breast reconstruction.

Abstract
OBJECTIVE Hemithyroidectomy is often performed in the pediatric population for indeterminate or benign thyroid nodules. Prior studies confirmed the safety of same-day discharge for adults undergoing hemithyroidectomy or total thyroidectomy, but this has not been studied thoroughly in the pediatric population. Our goal was to determine differences in pediatric patients undergoing hemithyroidectomy who were admitted versus discharged for complications or factors to support same-day discharge. STUDY DESIGN Retrospective cohort. SETTING Pediatric tertiary care hospital. METHODS This was a retrospective study of pediatric patients (0-18 years of age) undergoing hemithyroidectomy at a pediatric tertiary care hospital from 2003 to 2022. Perioperative variables and outcomes were gathered via manual chart review. RESULTS One hundred five pediatric patients who underwent hemithyroidectomy were identified. Ninety (86%) patients were admitted postoperatively, and 15 (14%) were discharged the same day. There were no differences in patient demographics, including age (P = 0.29) distance from the hospital (P = 0.08) or benign versus malignant pathology (P = 0.93). Surgical time in same-day discharges was significantly shorter (P = 0.0001; 138.6 minutes, SD = 66.0) versus admitted patients (204.2 minutes, SD = 48.6) Hemostatic agents were used more in same-day discharges at 53.3% versus 4.5% (P = 0.0001). Perioperative complications occurred in 2 (2.2%) admitted patients compared to none in the same-day discharge (P = 1.0). There were no readmissions within 30 days for same-day discharges. CONCLUSION In pediatric patients undergoing uncomplicated hemithyroidectomy, same-day discharge appears appropriate for those with shorter surgical times and intraoperative use of hemostatic agents with no readmissions or complications in those discharged the same day.

Abstract
Secondary hyperparathyroidism (SHPT) often arises from kidney disease and is characterized by elevated parathyroid hormone (PTH) levels. The reported optimal PTH level to balance the compensatory physiologic response in SHPT with the pathologic morbidity and mortality has changed over time with our evolving understanding. Parathyroidectomy for kidney-related hyperparathyroidism requires consideration of the patient's dialysis status, potential for kidney transplantation, and medical history. Extent of parathyroidectomy and intraoperative decision-making requires consideration to maximize cure with the risk of permanent hypoparathyroidism. Parathyroidectomy for kidney-related hyperparathyroidism can provide a reduction in morbidity, mortality, and improved kidney allograft function and survival.

Abstract
PURPOSE Ischemic complications after nipple-sparing mastectomy (NSM) can be ameliorated by 2-stage procedures wherein devascularization of the nipple-areolar complex (NAC) and lumpectomy with or without nodal staging surgery is performed first (1S), weeks prior to a completion NSM (2S). We report the time interval between procedures in relation to the presence of residual carcinoma at 2S NSM. METHODS Women with breast cancer who received 2S NSM from 2015 to 2022 were identified. Both patient level and breast level analyses were conducted. Clinical staging at presentation, pathologic staging at 1S and residual disease at 2S pathology are noted. Residual disease was classified as microscopic (1-2 mm), minimal (3-10 mm), and moderate (> 10 mm). RESULTS 59 patients (108 breasts) underwent 2S NSM. The median time interval between 1 and 2S for all patients was 34 days: 31 days for upfront surgery invasive cancer, 41 days for upfront DCIS surgery and 31 days for those receiving neoadjuvant therapy. Completion NSM was performed within 6 weeks for 72% of the breasts analyzed. Of the 53 breasts with invasive cancer on 1S pathology, 35% (19/53) had no residual invasive disease and 24.5% (13/53) had neither residual invasive nor in situ carcinoma on final 2S. Among the 50 women who had upfront surgery, 16 (32%) had residual invasive cancer found at 2S NSM, 9 of which had less than or equal to 1 cm disease. CONCLUSION Invasive cancers were completely resected during 1S procedure in 65% of breasts. Residual disease was minimal and there was only one case of upstaging at 2S. Added time of two-stage surgery is offset by a reduction in ischemic mastectomy flap complications.

Abstract
To investigate the potential molecular mechanism of miR-34a in Sjögren's syndrome (SS). Transmission electron microscopy was used to observe the salivary gland tissues of mild and severe SS patients. SS mouse model was constructed and injected with miR-34a antagonist. HSGE cells were transfected with miR-34a mimic. Starbase predicted miR-34a binding sites and validated them with dual-luciferase reporter assays. Immunohistochemistry, HE staining, CCK-8, TUNEL assay, flow cytometry, immunofluorescence and Western Blot were used to investigate the effects of miR-34a on NF-κB signaling and mitochondrial pathway of apoptosis in HSGE cells. Severe SS patients showed obvious mitochondrial damage and apoptosis in salivary glands. MiR-34a was overexpressed and NF-κB signaling is activated in salivary glands of severe SS patients. Inhibition of miR-34a alleviated salivary gland injury in SS mice, as well as inhibited the activation of NF-κB signaling and mitochondrial pathway of apoptosis. In conclusion, miR-34a promoted NF-κB signaling by targeting IκBα, thereby causing mitochondrial pathway apoptosis and aggravating SS-induced salivary gland damage.

Abstract
BACKGROUND Necrosis of a cutaneous flap including the nipple-areola complex is a common complication in immediate implant-based breast reconstruction following nipple-sparing mastectomy (NSM)/skin-sparing mastectomy (SSM). This study aimed to evaluate the efficacy of prostaglandin E1 (PGE1) in reducing such complications. METHODS A retrospective analysis of prospectively collected data was conducted at two centers, and the cohort consisted of patients undergoing NSM/SSM followed by immediate reconstruction with a prosthesis. Patients who were randomly allocated to the treatment group were administered daily intravenous PGE1 (10 μg/2 mL) beginning intraoperatively through postoperative day 6. Skin flap complications including nipple/skin necrosis, delayed wound healing, and postoperative wound revision were recorded. Complication rates were compared between the PGE1 and control groups. RESULTS A total of 276 breasts in 259 patients were included for analysis (139 breasts in the treatment group and 137 breasts in the control group). There was no difference in patient demographics between the control and treatment groups. Reconstructed breasts receiving PGE1 had significantly lower rates of overall skin complications (21.6% versus 34.3%; P = 0.022) and wound revision (2.9% versus 9.5%; P = 0.025). Among NSM cases, the PGE1 group showed a significantly lower rate of nipple necrosis (15.5% versus 29.4%; P = 0.027). In the multivariate analysis, the use of PGE1 significantly reduced the risk of overall skin flap complications (OR, 0.491; P = 0.018) and wound revision (OR, 0.213; P = 0.018) in NSM/SSM cases, and nipple necrosis (OR, 0.357; P = 0.008) in NSM cases. CONCLUSION PGE1 can be effective in reducing risk of mastectomy flap complications in immediate implant-based breast reconstructions. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
PURPOSE This study aims to explore heterogeneous trajectories of psychosocial adjustment among young to middle-aged women with breast cancer and determine the predictive factors influencing these trajectories. METHODS This study was conducted from October 2019 to October 2022 across two hospitals in Guangzhou. Demographic and disease characteristics, psychosocial adjustment, self-efficacy, social support, and coping modes were collected at baseline. Follow-up evaluations of psychosocial adjustment occurred at 1, 3, and 6 months post-surgery. Latent class growth modeling identified distinct patterns of psychosocial adjustment trajectories. Logistic regression analysis determined the predictive factors. RESULTS A total of 377 young to middle-aged women with breast cancer participated in this study, with 289 participants completing the 6-month follow-up. Three distinct trajectories of psychosocial adjustment were identified including a "sustained severe maladjustment" trajectory, comprising 22.5% of participants, a "sustained moderate maladjustment" trajectory, comprising 50.4% of participants, and a "well-adjusted class" trajectory, comprising 27.1% of participants. Predictors of psychosocial adjustment trajectories included affected side, surgical type, chemotherapy, self-efficacy, social support, and coping modes. CONCLUSIONS This study revealed three distinct trajectories of psychosocial adjustment among young to middle-aged women with breast cancer. Those with right-sided breast cancer, undergoing total mastectomy, receiving chemotherapy, low self-efficacy, limited social support, and relying on confrontation or avoidance coping modes may experience sustained maladjustment.

Successful localisation of recurrent thyroid cancer using preoperative patent blue dye injection. J Endocrinol Invest 2024; 47:1941-1951. [PMID: 38353922 PMCID: PMC11266229 DOI: 10.1007/s40618-024-02301-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Accepted: 01/01/2024] [Indexed: 07/25/2024]
Abstract
PURPOSE In the follow-up of patients with thyroid cancer, recurrences are often detected, posing challenges in locating and removing these lesions in a reoperative setting. This study aimed to assess the effectiveness of preoperative ultrasound (US)-guided injection of patent blue (PB) dye into the recurrences to aid in their safe and efficient removal. METHODS In this retrospective analysis, we reviewed the records of the patients in a tertiary care centre between February 2019 and March 2023 who underwent US-guided PB injection in the endocrinology outpatient clinic before reoperative neck surgery. The duration between the injection of PB and the initiation of surgery was recorded. The complications and effectiveness of the procedure were evaluated using ultrasonographic, laboratory, surgical, and pathologic records. RESULTS We reached 23 consecutive patients with 28 lesions. The recurrences averaged 8.8 mm (4.1-15.6) in size and were successfully stained in all cases. The median time between the PB injection and the incision was 90 (35-210) min. There were no complications related to the dye injection. The blue recurrences were conveniently identified and removed in all cases. CONCLUSIONS A preoperative US-guided injection of PB is a safe, readily available and highly effective technique for localising recurrent tumours, even in small lesions within scarred reoperative neck surgeries.

Controversies in point-of-care 3D printing for oncological and reconstructive surgery with free software in oral and maxillofacial surgery: European regulations, costs, and timeframe. Int J Oral Maxillofac Surg 2024; 53:650-660. [PMID: 38290865 DOI: 10.1016/j.ijom.2024.01.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 12/01/2023] [Accepted: 01/05/2024] [Indexed: 02/01/2024]
Abstract
The aim of this paper is to discuss the controversies surrounding the most recent European regulations, as well as the cost, for a 3D printing workflow using free-source software in the context of a tertiary level university hospital in the Spanish public health system. Computer-aided design and manufacturing (CAD/CAM) for head and neck oncological surgery with the printing of biomodels, cutting guides, and patient-specific implants has made it possible to simplify and make this type of highly complex surgery more predictable. This technology is not without drawbacks, such as increased costs and the lead times when planning with the biomedical industry. A review of the current European legislation and the literature on this subject was performed, and comparisons made with the authors' in-house 3D printing setup using free software and different 3D printers. The cost analysis revealed that for the cheapest setup with free software, it would be possible to amortize the investment from case 2, and in all cases the initial investment would be amortized before case 9. The timeframe ranged from 2 weeks with the biomedical industry to 72 h with point-of-care 3D printing. It is now possible to develop point-of-care 3D printing in any hospital with almost any budget.

Oncol Lett 2024; 28:389. [PMID: 38966584 PMCID: PMC11223028 DOI: 10.3892/ol.2024.14522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Accepted: 06/03/2024] [Indexed: 07/06/2024] Open
Abstract
The present study aimed to investigate whether local recurrence (LR) after nipple-sparing mastectomy (NSM) and reconstruction was associated with i) Ki67 values and molecular subtypes of the initial lesions, and ii) the size of the initial tumor and the size of the implant. A total of 156 patients with breast cancer with a mean age of 51.58 years (age range, 26-75 years) who underwent NSM with primary implant breast reconstruction were analyzed. After surgery, the mean follow-up time was 59.26 months (range, 17-85 months). Molecular subtypes, Ki67 values, estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) status were recorded for each patient. Additionally, information regarding the size of the implant and the initial tumor size were collected. The information was used to assess LR. For univariate analyses of risk factors, χ2 test, Fisher's exact test, Mann-Whitney U test and Student's t-test for independent samples were used. For multivariate analyses, a Cox proportional-hazards model was used. NSM was the primary treatment for breast cancer in 34/156 patients (21.8%), while 122/156 (78.2%) of patients received neoadjuvant chemotherapy followed by surgery. Luminal B was the most frequent molecular subtype, detected in 82/156 patients (52.6%), whereas the luminal A subtype was detected in 37 patients (23.7%) and the HER2-enriched subtype was detected in 17/156 patients (10.9%). Ki67 expression was low in 13/156 patients (8.3%), while medium expression was detected in 78/156 patients (50.0%) and high expression was present in 58/156 patients (37.2%). LR was noted in 17/156 patients (10.9%). As determined by univariate analysis, lower ER (P=0.010) and PR (P=0.008) expression were indicated to be significant risk factors for LR. In conclusion, in the present patient cohort, low ER and PR expression were risk factors for LR of breast cancer, whereas Ki67 status and molecular subtype were not statistically significant risk factors for LR. Additionally, the size of the initial tumor and the size of the implant were not risk factors for LR. These findings are consistent with the current literature, and should be utilized when discussing treatment options and potential clinical outcomes with patients prior to surgical management.

Abstract
INTRODUCTION Ultrasonography (US) features of papillary thyroid cancers (PTCs) are used to select nodules for biopsy due to their association with tumor behavior. However, the molecular biological mechanisms that lead to the characteristic US features of PTCs are largely unknown. OBJECTIVES This study aimed to investigate the molecular biological mechanisms behind US features assessed by radiologists and three convolutional neural networks (CNN) through transcriptome analysis. METHODS Transcriptome data from 273 PTC tissue samples were generated and differentially expressed genes (DEGs) were identified according to US feature. Pathway enrichment analyses were also conducted by gene set enrichment analysis (GSEA) and ClusterProfiler according to assessments made by radiologists and three CNNs - CNN1 (ResNet50), CNN2 (ResNet101) and CNN3 (VGG16). Signature gene scores for PTCs were calculated by single-sample GSEA (ssGSEA). RESULTS Individual suspicious US features consistently suggested an upregulation of genes related to immune response and epithelial-mesenchymal transition (EMT). Likewise, PTCs assessed as positive by radiologists and three CNNs showed the coordinate enrichment of similar gene sets with abundant immune and stromal components. However, PTCs assessed as positive by radiologists had the highest number of DEGs, and those assessed as positive by CNN3 had more diverse DEGs and gene sets compared to CNN1 or CNN2. The percentage of PTCs assessed as positive or negative concordantly by radiologists and three CNNs was 85.6% (231/273) and 7.1% (3/273), respectively. CONCLUSION US features assessed by radiologists and CNNs revealed molecular biologic features and tumor microenvironment in PTCs.

Abstract
BACKGROUND Metabolic and bariatric surgery (MBS) is the most effective and durable treatment for obesity. We aimed to compare the trajectories of antihypertensive medication (AHM) use among obese individuals treated and not treated with MBS. METHODS Adults with a body mass index of ≥35 kg/m2 were identified in the Merative Database (US employer-based claims database). Individuals treated with versus without MBS were matched 1:1 using baseline demographic and clinical characteristics as well as AHM utilization. Monthly AHM use was examined in the 3 years after the index date using generalized estimating equations. Subanalyses investigated rates of AHM discontinuation, AHM initiation, and apparent treatment-resistant hypertension. RESULTS The primary cohort included 43 206 adults who underwent MBS matched with 43 206 who did not. Compared with no MBS, those treated with MBS had sustained, markedly lower rates of AHM use (31% versus 15% at 12 months; 32% versus 17% at 36 months). Among patients on AHM at baseline, 42% of patients treated with MBS versus 7% treated medically discontinued AHM use (P<0.01). The risk of apparent treatment-resistant hypertension was 3.41× higher (95% CI, 2.91-4.01; P<0.01) 2 years after the index date in patients who did not undergo MBS. Among those without hypertension treated with MBS versus no MBS, 7% versus 21% required AHM at 2 years. CONCLUSIONS MBS is associated with lower rates of AHM use, higher rates of AHM discontinuation, and lower rates of AHM initiation among patients not taking AHM. These findings suggest that MBS is both an effective treatment and a preventative measure for hypertension.

Abstract
OBJECTIVES Pheochromocytomas (PHEO) are neuroendocrine tumors rarely diagnosed in children. We are reporting on the management challenges of three adolescent patients who present with hereditary PHEO. CASE PRESENTATION The index patient and his male sibling presented with bilateral PHEO, while a third patient presented with a unilateral PHEO, all associated with von Hippel-Lindau (VHL) syndrome. The patients were treated with computed tomography (CT)-guided percutaneous cryoablation (CRA) of the adrenal lesions, with varying degrees of success. CONCLUSIONS CT-guided percutaneous CRA of hereditary PHEO has not been reported in the pediatric population and may represent a novel treatment strategy that reduces the risk of intraprocedural complications and adrenal insufficiency (AI).

Abstract
The pancreas is adjacent to critical organs; excessive microwave ablation (MWA) can result in serious complications. The purpose of this paper is to provide the reference data of pancreas MWA for clinicians, analyze the ablation outcomes under different ablation parameters, and determine the critical temperature of pancreatic surface fat liquefaction outflow. Combinations of two power levels (30 W and 55 W), three antenna diameters (1.3 mm, 1.6 mm, and 1.9 mm), and three ablation times (1 min, 1.5 min, and 2 min) were applied to an ex vivo pig pancreas. Temperature measurements were taken at four thermocouple points. The center point is located 5 mm horizontally from the antenna slot, with a temperature measurement point located 5 mm above, below, and to the right of the center point. Main effect analysis and variance analysis were used to quantify the influences of each factor on the ablation outcomes. At 30 W, the antenna diameter contributing the most at 48.5%. At 30 W-1.3 mm-1 min, the spherical index (1.41) is closest to 1. At 55 W, the coagulation zone size was almost only affected by the ablation time, with a contribution rate of 28.7%, the temperature at point C exceeds point B. On the surface of the ex vivo porcine pancreas, the fat outflow temperature was 54ã. Ablation combinations with low power, short duration, and small antenna diameter results in a more nearly spherical coagulation zone. When performing MWA on the pancreas, it is advisable to avoid areas with higher fat content, while keeping the pancreatic surface temperature below 54°C.

Abstract
OBJECTIVE The research aimed to determine whether and which radiomic features from breast dynamic contrast enhanced (DCE) MRI could predict the presence of BRCA1 mutation in patients with triple-negative breast cancer (TNBC). MATERIAL AND METHODS This retrospective study included consecutive patients histologically diagnosed with TNBC who underwent breast DCE-MRI in 2010-2021. Baseline DCE-MRIs were retrospectively reviewed; percentage maps of wash-in and wash-out were computed and breast lesions were manually segmented, drawing a 5 mm-Region of Interest (ROI) inside the tumor and another 5 mm-ROI inside the contralateral healthy gland. Features for each map and each ROI were extracted with Pyradiomics-3D Slicer and considered first separately (tumor and contralateral gland) and then together. In each analysis the more important features for BRCA1 status classification were selected with Maximum Relevance Minimum Redundancy algorithm and used to fit four classifiers. RESULTS The population included 67 patients and 86 lesions (21 in BRCA1-mutated, 65 in non BRCA-carriers). The best classifiers for BRCA mutation were Support Vector Classifier and Logistic Regression in models fitted with both gland and tumor features, reaching an Area Under ROC Curve (AUC) of 0.80 (SD 0.21) and of 0.79 (SD 0.20), respectively. Three features were higher in BRCA1-mutated compared to non BRCA-mutated: Total Energy and Correlation from gray level cooccurrence matrix, both measured in contralateral gland in wash-out maps, and Root Mean Squared, selected from the wash-out map of the tumor. CONCLUSIONS This study showed the feasibility of a radiomic study with breast DCE-MRI and the potential of radiomics in predicting BRCA1 mutational status.

Abstract
Laparoscopic adrenalectomy is worldwide currently considered the gold standard technique for patients suffering from benign lesions. There has been an increasing number of robotic-assisted adrenalectomies in the last decade due to the systematic further development of minimally invasive surgery resulting in the implementation of robot-assisted surgery. Interestingly, the available studies show some perioperative advantages for robotic surgery but overall the current evidence is weak and there are economic aspects that are not negligible. Therefore, further high-quality studies about robotic-assisted adrenalectomy are mandatory to strengthen the current evidence.

Abstract
OBJECTIVE The generally good prognosis of low- and intermediate-risk differentiated thyroid cancer (DTC) underscored the need to identify those few patients who relapse. DESIGN Records of 299 low- or intermediate-risk DTC patients (mean follow-up 8.2 ± 6.2 years) were retrospectively reviewed. The sample was classified following the American Thyroid Association (ATA) dynamic risk stratification (DRS) system. PATIENTS AND MEASUREMENT After classifying patients according to DRS at the first visit following initial therapy (FU1), structural recurrence occurred in 2/181 (1.1%), 5/81 (6.2%) and 13/26 (50.0%) with excellent, indeterminate and biochemical incomplete response to treatment, respectively. All relapses but one happened within 5 years from FU1. Univariate analysis comparing excellent, indeterminate and biochemical incomplete with structural incomplete responses at the end of the follow-up, identified tumour size (p < .001), T status (<0.001), positive lymph nodes (N) (p < .01), multifocality (p < .004), need of additional radioactive iodine (RAI) (p < .0001) and first DRS status (p < .0003) as risk factors of recurrence. In the multivariate analysis, only RAI remained statistically significant (p < .02). Comparison between excellent and indeterminate with biochemical and structural incomplete responses, identified tumour size (p < .0004), T (p < .01), N (p < .0001), bilaterality (p < .03), first DRS status (p < .0001) and RAI (p < .001) as recurrence risk factors. T (p < .01) and first DRS (p < .0006) were confirmed in the multivariate analysis. CONCLUSIONS Patients with DTC classified as low- or intermediate-risk of recurrence with excellent response to treatment at FU1 rarely develop structural disease and this occurs almost exclusively in the first 5 years. Initial DRS status is an accurate tool for determining the risk of recurrence.

Abstract
BACKGROUND Microsurgical breast reconstruction using abdominal tissue is a complex procedure, in part, due to variable vascular/perforator anatomy. Preoperative computed tomography angiography (CTA) has mitigated this challenge to some degree; yet it continues to pose certain challenges. The ability to map perforators with Mixed Reality has been demonstrated in case studies, but its accuracy has not been studied intraoperatively. Here, we compare the accuracy of "HoloDIEP" in identifying perforator location (vs. Doppler ultrasound) by using holographic 3D models derived from preoperative CTA. METHODS Using a custom application on HoloLens, the deep inferior epigastric artery vascular tree was traced in 15 patients who underwent microsurgical breast reconstruction. Perforator markings were compared against the 3D model in a coordinate system centered on the umbilicus. Holographic- and Doppler-identified markings were compared using a perspective-corrected photo technique against the 3D model along with measurement of duration of perforator mapping for each technique. RESULTS Vascular points in HoloDIEP skin markings were -0.97 ± 6.2 mm (perforators: -0.62 ± 6.13 mm) away from 3D-model ground-truth in radial length from the umbilicus at a true distance of 10.81 ± 6.14 mm (perforators: 11.40 ± 6.15 mm). Absolute difference in radial distance was twice as high for Doppler markings compared with Holo-markings (9.71 ± 6.16 and 4.02 ± 3.20 mm, respectively). Only in half of all cases (7/14), more than 50% of the Doppler-identified points were reasonably close (<30 mm) to 3D-model ground-truth. HoloDIEP was twice as fast as Doppler ultrasound (76.9s vs. 150.4 s per abdomen). CONCLUSION HoloDIEP allows for faster and more accurate intraoperative perforator mapping than Doppler ultrasound.

Abstract
BACKGROUND AND OBJECTIVE Surgical site infection (SSI) is common in surgery for malignant musculoskeletal tumours, specifically those arising from the trunk. In this study, we investigated the risk factors for SSI after resection of musculoskeletal tumours of the trunk. METHODS This retrospective observational study included 125 patients (72 males, 53 females) with musculoskeletal tumours of the trunk in our hospital from 1 April 2008 to 31 August 2023. The incidence of SSI and its risk factors were investigated. RESULTS SSI was observed in 26% (32/125), and the median time to SSI was 22 days. On multivariate analysis, the following were identified as risk factors for SSI: tumours arising caudal to Jacoby's line (hazard ratio [HR] 4.04; P = .0107), soft tissue reconstruction (HR 3.43; P = .0131), and low Geriatric Nutritional Risk Index (GNRI) (HR 0.96; P = .0304). Patients were classified into two risk categories based on GNRI scores: the risk group (GNRI ≤98) and no risk group (>98). The risk group showed a significantly lower overall noninfection survival rate (P = .023). CONCLUSION Tumours arising caudal to Jacoby line, soft tissue reconstruction, and lower GNRI were risk factors for SSI. Preoperative and postoperative nutritional interventions should be considered to improve GNRI.
