The glomus tumor is a rare neoplasm that is typically found subungually in the extremities and functions as a specialized neurovascular organ. An extremely rare site for glomus tumors is the breast, with only a few reported cases. Breast glomus tumors present with three typical clinical signs: dull pain, focal tenderness, and cold sensitivity. Less than 10% of all glomus tumors are malignant. We herein present a case of a malignant glomus tumor originating in the breast. Distant metastasis was ruled out, and the tumor was completely resected. However, the patient unexpectedly developed rapid systemic metastasis, detected 5 weeks after tumor removal. Despite the administration of analgesics and targeted therapy, the patient died 1 month later. When treating patients with undiagnosed breast tumors, clinicians should pay attention to unexplained and repeatedly reported symptoms and consider the possibility of a rare disease. Our literature search revealed no cases of malignant glomus tumors originating in the breast, making this case the first of its kind.

UNASSIGNED: Rapid progression of coronary non-target lesions is essential for the determination of future cardiovascular events. Clinical factors that predict rapid progression of non-target lesions are unclear. The purpose of this study was to identify the clinical predictors of rapid progression and revascularization of coronary non-target lesions.
UNASSIGNED: Consecutive patients with coronary heart disease who had undergone two serial coronary angiograms were enrolled. All coronary non-target lesions were identified and evaluated at both procedures. Multivariable Cox regression analysis was used to investigate the clinical risk factors associated with rapid progression or revascularization of coronary non-target lesions.
UNASSIGNED: A total of 1255 patients and 1670 lesions were enrolled. In this cohort of patients, 239 (19%) had rapid progression and 186 (14.8%) underwent revascularization. At the lesion level, 251 (15.0%) had rapid progression and 194 (11.6%) underwent revascularization. The incidence of lesion revascularization and myocardial infarction was significantly higher in patients with rapid progression. In multivariable analyses, hypertension (hazard ratio [HR], 0.76; 95% confidence interval [95% CI], 0.58-1.00; p = 0.049), ST-segment elevation myocardial infarction (STEMI) (HR, 1.46; 95% CI, 1.03-2.07; p = 0.035), glycosylated hemoglobin (HR, 1.16; 95% CI, 1.01-1.33; p = 0.039) and lesion classification (B2/C versus A/B1) (HR, 1.73; 95% CI, 1.27-2.35; p = 0.001) were significant factors associated with rapid progression. The level of triglycerides (HR, 1.10; 95% CI, 1.00-1.20; p = 0.040) and lesion classification (B2/C versus A/B1) (HR, 1.53; 95% CI, 1.09-2.14; p = 0.014) were predictors of lesion revascularization.
UNASSIGNED: Hypertension, STEMI, glycosylated hemoglobin and lesion classification may be used as predictors of rapid progression of coronary non-target lesions. The level of triglyceride and lesion classification may predict the revascularization of non-target lesions. In order to prevent future cardiovascular events, increased attention should be paid to patients with these factors.

Alzheimer\'s disease (AD) is the most common type of cognitive impairment in the elderly. In this report, we presented a case of a 52-year-old woman with rapid disease progression within 6 months. She was diagnosed with mild dementia according to the clinical symptoms and neuropsychological assessment results. Based on the results of neuropathological proteins in cerebrospinal fluid, cranial magnetic resonance imaging, and positron emission tomography/computed tomography, the patient showed the presence of β amyloid deposition, pathologic tau along with neurodegeneration [A+T+(N+)], indicative of AD. Whole exome sequencing revealed a heterozygous C-to-T missense mutation of nucleotide 3,755 (c.3755C > T) in exon 25 of the angiotensin converting enzyme (ACE) gene on chromosome 17q23 (rs762056936).

UNASSIGNED: Surgical cerebral revascularization is recommended for treating pediatric moyamoya disease (MMD). However, whether unilateral combined bypass surgery can cause disease progression on the contralateral side is uncertain. The study aimed to investigate the vascular architecture and regional cerebral blood flow (rCBF) status of patients with pediatric MMD after successful unilateral combined bypass surgery and to identify the possible risk factors.
UNASSIGNED: Pediatric patients diagnosed with MMD and admitted to Xuanwu Hospital who underwent combined bypass surgery between 2019 and 2021 were enrolled. Digital subtraction angiography (DSA) and magnetic resonance imaging (MRI) with arterial spin labeling (ASL) were performed to investigate the vascular architecture and rCBF during surgery and at short-term follow-up. Suzuki\'s angiographic staging and moyamoya vessel grading system were both used. Progression was defined as an increase in either Suzuki stage or moyamoya vessel grade detected after unilateral surgery. All analyses were performed with conventional statistic methods.
UNASSIGNED: A total of 27 successive patients with a median age of 8 [interquartile range (IQR), 5-14] years old were identified. On the non-operated (non-OP) side, 11 (40.7%) patients demonstrated progression, all of whom showed an increase in the moyamoya vessel grade, and 5 also displayed Suzuki stage progression during the median 4.7 (IQR, 3.7-5.7) months follow-up. However, rCBF barely changed on the non-OP side compared to preoperation [preoperation: median, 49.6, (IQR, 42.9-61.1) mL/100 g/min; postoperation: median, 50.2, (IQR, 43.5-59.3) mL/100 g/min; P=0.445].
UNASSIGNED: Combined bypass surgery might accelerate the radiological progression on the contralateral side, which occurs before the decline of rCBF. Those with earlier Suzuki stage MMD of the non-OP side are prone to rapid progression after unilateral combined revascularization.

UNASSIGNED: This study aimed to determine the utility of different methods to predict rapid progressors (RPs) and their clinical characteristics in Asia-Pacific patients with autosomal dominant polycystic kidney disease (ADPKD).
UNASSIGNED: This was a multinational retrospective observational cohort study of patients with ADPKD in the Asia-Pacific region. Five hospitals from Australia, China, South Korea, Taiwan, and Turkey participated in this study. RP was defined by European Renal Association-European Dialysis and Transplantation Association (ERA-EDTA) guidelines and compared to slow progressors (SPs).
UNASSIGNED: Among 768 patients, 426 patients were RPs. Three hundred six patients met only 1 criterion and 120 patients satisfied multiple criteria for RP. Historical estimated glomerular filtration rate (eGFR) decline fulfilled the criteria for RP in 210 patients. Five patients met the criteria for a historical increase in height-adjusted total kidney volume (TKV). The 210 patients satisfied the criteria for based on kidney volume. During the follow-up period, cyst infections, cyst hemorrhage, and proteinuria occurred more frequently in RP; and 13.9% and 2.1% of RPs and SPs, respectively, progressed to end-stage kidney disease (ESKD). RP criteria based on historical eGFR decline had the strongest correlation with eGFR change over a 2-year follow-up.
UNASSIGNED: Various assessment strategies should be used for identifying RPs among Asian-Pacific patients with ADPKD in real-world clinical practice during the follow-up period, cyst infections, cyst hemorrhage, and proteinuria occurred more frequently; and more patients progressed to ESKD in RPs compared with SPs.

UNASSIGNED: Necrotizing enterocolitis (NEC) is a devastating gastrointestinal emergency with significant mortality and morbidity rates. A subset of patients progressed rapidly and underwent surgical intervention within a short period. This study aimed to establish a model to predict the rapid progression of NEC in preterm neonates.
UNASSIGNED: A retrospective study was conducted to review neonates with NEC between December 2015 and April 2019 at the Guangzhou Women and Children\'s Medical Center. Rapidly progressive NEC was defined as the need for surgical intervention or death within 48 h of NEC onset. Patients were divided into two groups: rapidly progressive NEC (RP-NEC) and non-rapidly progressive NEC (nRP-NEC). Data on demographics, perinatal characteristics, examination variables, and radiographic findings at onset were collected.
UNASSIGNED: A total of 216 preterm neonates with NEC were included in the study, of which 64 had RP-NEC and 152 had nRP-NEC. The mortality rates of patients with RP-NEC and nRP-NEC were 32.8% and 3.28%, respectively. Male sex (p-value, adjusted odds ratio [95% confidence interval]: 0.002, 3.43 [1.57, 7.53]), portal venous gas (0.000, 8.82 [3.73, 20.89]), neutrophils <2.0 × 109/L (0.005, 4.44 [1.59, 12.43]), pH <7.3 (7.2 ≤ pH < 7.3) (0.041, 2.95 [1.05, 8.31]), and pH <7.2 (0.000, 11.95 [2.97, 48.12]) at NEC onset were identified as independent risk factors for RP-NEC. An established model that included the four risk factors presented an area under the curve of 0.801 with 83% specificity and 66% sensitivity.
UNASSIGNED: Among preterm neonates with NEC, a significantly higher mortality rate was observed in those with rapid progression. It is recommended that close surveillance be performed in these patients, and we are confident that our established model can efficiently predict this rapid progression course.

BACKGROUND: The protective effect of tracheal stents is reported to relieve airway obstruction and reduce side effects of rapid progression of malignant tracheoesophageal fistula (MTEF) after immunotherapy in this case with 10 mo follow-up.
METHODS: Two kinds of silicone stents were placed in the main airway of a 58-year-old male to relieve the airway obstruction caused by advanced esophageal carcinoma. The patient then received four doses of toripalimab. Subsequently, rapid, progressive deterioration of the original fistula was found. Although the fistula enlarged rapidly after immunotherapy, it remained covered completely, and likely because of this, his condition remained stable. Therefore, immunotherapy could be continued to treat the primary tumor. Despite these efforts, the patient died of the advancement of his esophageal cancer.
CONCLUSIONS: Appropriately-sized tracheal stent placement combined with immune checkpoint inhibitors may improve the quality of life and survival of patients with MTEF.

There is heterogeneity in cancer patients\' responses to immune checkpoint inhibitors (ICIs), including hyperprogression, which is very rapid tumor progression following immunotherapy, and pseudoprogression, which is an initial increase followed by a decrease in tumor burden or in the number of tumor lesions. This heterogeneity complicates clinical decisions because either premature withdrawal of the treatment or prolonged ineffective treatment harms patients. We presented two patients treated with ICIs with heterogeneous responses. One patient had Merkel cell carcinoma in the right thigh, and the other had nasopharyngeal squamous carcinoma. The first patient was treated with sintilimab and the second with sintilimab combined with abraxane. In the first patient, subcutaneous lesions grew substantially after the first cycle of treatment with sintilimab. In the second patient, subcutaneous lesions grew gradually after the second cycle of treatment with sintilimab combined with abraxane. In both cases, biopsy examination confirmed that newly emerged lesions were metastases of the primary tumor. These two cases remind clinicians that when subcutaneous nodules appear after treatment with ICIs, pathological biopsy is needed to determine the nature-pseudoprogression or rapid progression-of the disease course.

UNASSIGNED: Mounting evidence indicates that rapid progression of aortic stenosis (AS) is significantly associated with poor prognosis. Whether diabetes accelerates the progression of AS remains controversial.
UNASSIGNED: The purpose of the present study was to investigate whether diabetes was associated with rapid progression of AS.
UNASSIGNED: We retrospectively analyzed 276 AS patients who underwent transthoracic echocardiography at least twice with a maximum interval ≥ 180 days from January 2016 to June 2021. AS severity was defined by specific threshold values for peak aortic jet velocity (Vmax) and/or mean pressure gradient. An increase of Vmax ≥ 0.3 m/s/year was defined as rapid progression. The binary Logistic regression models were used to determine the association between diabetes and rapid progression of AS.
UNASSIGNED: At a median echocardiographic follow-up interval of 614 days, the annual increase of Vmax was 0.16 (0.00-0.41) m/s. Compared with those without rapid progression, patients with rapid progression were older and more likely to have diabetes (P = 0.040 and P = 0.010, respectively). In the univariate binary Logistic regression analysis, diabetes was associated with rapid progression of AS (OR = 2.02, P = 0.011). This association remained significant in the multivariate analysis based on model 2 and model 3 (OR = 1.93, P = 0.018; OR = 1.93, P = 0.022). After propensity score-matching according to Vmax, diabetes was also associated rapid progression of AS (OR = 2.57, P = 0.045).
UNASSIGNED: Diabetes was strongly and independently associated with rapid progression of AS.
