Somatostatin receptor-targeted α-therapy using α-emitter 225Ac-labeled somatostatin analogs has been suggested as a treatment option in advanced metastatic neuroendocrine tumors (NETs) failing treatment with β-emitters, such as 177Lu or 90Y. Thymus NETs are rare and usually more aggressive than other neuroendocrine tumor entities. We present here a case with β-radiation refractory metastatic thymus NET, who demonstrated an excellent therapy response (molecular and morphological remission, as well as significantly improved clinical symptoms) after 225Ac-DOTATOC-targeted α-therapy, without any adverse effects during the treatment or in the follow-up period.

Ictal brain perfusion SPECT with the tracer 99mTc-HMPAO or 99mTc-ECD is widely used for identification of the epileptic seizure onset zone (SOZ) in presurgical evaluation if standard pointers are uncertain or inconsistent. For both tracers, there are theoretical arguments to favor it over the other for this task. The aim of this study was to compare the performance of ictal brain perfusion SPECT between 99mTc-HMPAO and 99mTc-ECD in a rather large patient sample.

The study retrospectively included 196 patients from clinical routine in whom ictal perfusion SPECT had been performed with stabilized 99mTc-HMPAO (n = 110) or 99mTc-ECD (n = 86). Lateralization and localization of the SOZ were obtained by the consensus of 2 independent readers based on visual inspection of the SPECT images.

The 99mTc-HMPAO group and the 99mTc-ECD group were well matched with respect to age, sex, age at first seizure, duration of disease, seizure frequency, history of previous brain surgery, and findings of presurgical MRI. The proportion of lateralizing ictal SPECT did not differ significantly between 99mTc-HMPAO and 99mTc-ECD (65.5% vs 72.1%, P = 0.36). Sensitivity of ictal perfusion SPECT (independent of the tracer) for correct localization of the SOZ in 62 patients with temporal lobe epilepsy and at least worthwhile improvement (Engel scale ≤ III) 12 months after temporal epilepsy surgery was 63%.

This study does not provide evidence to favor 99mTc-HMPAO or 99mTc-ECD for identification of the SOZ by ictal perfusion SPECT.

A 40-year-old man presented with abdominal pain and diarrhea for 2 months. Abdominal CT showed thickening of the cecal wall, which was considered likely malignant. The patient was subsequently enrolled in a clinical trial of 68Ga-FAPI PET/CT study in tumors. Intense 68Ga-FAPI activity was noted in the thickened cecum, also suggestive of malignancy. However, pathological examination from biopsy rendered a diagnosis of chronic colitis.

The availability of automated, accurate, and robust gross tumor volume (GTV) segmentation algorithms is critical for the management of head and neck cancer (HNC) patients. In this work, we evaluated 3 state-of-the-art deep learning algorithms combined with 8 different loss functions for PET image segmentation using a comprehensive training set and evaluated its performance on an external validation set of HNC patients.

18F-FDG PET/CT images of 470 patients presenting with HNC on which manually defined GTVs serving as standard of reference were used for training (340 patients), evaluation (30 patients), and testing (100 patients from different centers) of these algorithms. PET image intensity was converted to SUVs and normalized in the range (0-1) using the SUVmax of the whole data set. PET images were cropped to 12 × 12 × 12 cm3 subvolumes using isotropic voxel spacing of 3 × 3 × 3 mm3 containing the whole tumor and neighboring background including lymph nodes. We used different approaches for data augmennd cross-entropy for Res-Net, Dense-VNet, and Dice plus XEnt for NN-UNet emerged as reliable networks for GTV delineation. Caution should be exercised for clinical deployment owing to the occurrence of outliers in deep learning-based algorithms.
A 61-year-old man after resection of well-differentiated midgut neuroendocrine neoplasia (NEN) was referred to 18F-fluorodihydroxyphenylalanine PET/CT for localization of recurrent midgut NEN in the context of clinical symptoms and mild elevation of serum CgA (chromogranin A) levels. Isolated hepatic focus of increased 18F-Fluorodihydroxyphenylalanine uptake was detected. The biopsy of this focus, followed by radiofrequency ablation, revealed a hepatic cavernous hemangioma. Complete remission of midgut NEN was confirmed during 4-year clinical and imaging follow-up. The persistent mild elevation of serum CgA was retrospectively attributed to treatment with proton-pump inhibitors.

The study aims to assess minimal apparent diffusion coefficient (ADCmin) and SUVmax as predictors of histological differentiation in patients with anal squamous cell carcinoma (ASCC) and to determine cutoff values for each histopathological tumor grade.

A retrospective study of 41 ASCC patients (14 males, 27 females; mean age, 65 ± 13 years) staged with FDG PET/CT and MRI (mean scan time interval, 21 ± 11 days). SUVmax and ADCmin values were measured and compared with histopathological tumor grading obtained from biopsy.

The mean size and tumor volume were 3 ± 2 cm and 16.5 ± 27.3 cm3, respectively. The mean ADCmin values for well-, moderately, and poorly differentiated ASCC were 935 ± 179, 896 ± 123, and 637 ± 114, respectively. link3 The mean SUVmax for well-, moderately, and poorly differentiated ASCC were 6.9 ± 1.8, 11.5 ± 4.1, and 13.4 ± 2.6, respectively. The difference in mean ADCmin values between poorly and moderately/well-differentiated tumors was statistically significant, whereas this was not signx values correlated with the degree of differentiation in ASCC and can be used as predictors of tumor grading and aggressiveness. Combined ADCmin and SUVmax cutoff values can therefore be used for early patient risk stratification and treatment decision making.
The aim of the study was to evaluate the clinical utility of pretreatment 18F-FDG PET/CT with quantitative evaluation of peritoneal metabolic cartography in relation to staging laparoscopy for ovarian carcinomatosis.

A retrospective review of prospectively collected data from 84 patients with FIGO (International Federation of Gynecology and Obstetrics) stage IIIC to IV ovarian cancer was carried out. All patients had a double-blinded 18F-FDG PET/CT review. Discriminant capacity of metabolic parameters to identify peritoneal carcinomatosis in the 13 abdominal regions according to the peritoneal cancer index was estimated with area under the receiver operating characteristic curve (AUC).

The metabolic parameter showing the best trade-off between sensitivity and specificity to predict peritoneal extension compared with peritoneal cancer index score was the metabolic tumor volume (MTV), with a Spearman ρ equal to 0.380 (P < 0.001). The AUC of MTV to diagnose peritoneal involvement in the upper abdomen (regions 1, 2, and 3) ranged from 0.740 to 0.765. MTV AUC values were lower in the small bowel regions (9-12), ranging from 0.591 to 0.681, and decreased to 0.487 in the pelvic region 6. 18F-FDG PET/CT also improved the detection of extra-abdominal disease, upstaging 35 patients (41.6%) from stage IIIC to IV compared with CT alone and leading to treatment modification in more than one third of patients.

18F-FDG PET/CT metrics are highly accurate to reflect peritoneal tumor burden, with variable diagnostic value depending on the anatomic region. MTV is the most representative metabolic parameter to assess peritoneal tumor extension.

The rapid acceleration of virtual health care delivery, telehealth, has underlined the pressing need for graduate nursing students to gain skills and competencies that will ensure effective and efficient delivery of telehealth care in future generations.

There is a need for graduate nursing students to be prepared to use telehealth, but few nursing programs offer this training. Barriers to this implementation may be due to lack of faculty knowledge, telehealth resources, or telehealth opportunities.

Graduate nursing faculty should use resources and the wisdom of early adopters of telehealth to ensure adequate telehealth preparation is integrated into all graduate nursing programs.

This article describes emerging core competencies for telehealth education and offers guidance, resources, and activities for nurse educators who seek to prepare emerging advanced practice RNs to plan, deliver, and implement effective telehealth practices.

Given global trends in obesity and bariatric surgeries, there are an increasing number of women presenting for breast reconstruction after massive weight loss. There is a paucity of literature about breast reconstruction after mastectomy in patients with a history of massive weight loss. A literature review revealed 10 articles that discussed outcomes of different reconstruction techniques in patients with massive weight loss. Autologous reconstruction techniques and implant-based reconstruction techniques were assessed to evaluate the advantages, disadvantages, and indications of each approach specific to this unique patient population. This article provides a summary of expected outcomes, including complication profiles. Ultimately, consideration should be given for breast reconstruction of mastectomy defects in patients with a history of massive weight loss, as satisfactory results are demonstrated to be possible. Both autologous reconstruction and implant-based reconstruction present feasible options, although reconstruction in this patient population may be associated with increased need for revisions and a higher complication rate compared with patients without a history of massive weight loss.
