    Abstract: ... positron emission tomography (PET) radioligand imaging with the D3 dopamine receptor preferring agonist [¹¹C]-(+)-propyl ...

    Abstract Dopamine agonist medications with high affinity for the D3 dopamine receptor are commonly used to treat Parkinson's disease, and have been associated with pathological behaviors categorized under the umbrella of impulse control disorders (ICD). The aim of this study was to investigate whether ICD in Parkinson's patients are associated with greater D3 dopamine receptor availability. We used positron emission tomography (PET) radioligand imaging with the D3 dopamine receptor preferring agonist [¹¹C]-(+)-propyl-hexahydro-naphtho-oxazin (PHNO) in Parkinson's patients with (n = 11) and without (n = 21) ICD, and age-, sex-, and education-matched healthy control subjects (n = 18). Contrary to hypotheses, [¹¹C]-(+)-PHNO binding in D3 -rich brain areas was not elevated in Parkinson's patients with ICD compared with those without; instead, [¹¹C]-(+)-PHNO binding in ventral striatum was 20% lower (P = 0.011), correlating with two measures of ICD severity (r = -0.8 and -0.9), which may reflect higher dopamine tone in ventral striatum. In dorsal striatum, where [¹¹C]-(+)-PHNO binding is associated with D2 receptor levels, [¹¹C]-(+)-PHNO binding was elevated across patients compared with controls. We conclude that although D3 dopamine receptors have been linked to the occurrence of ICD in Parkinson's patients. Our findings do not support the hypothesis that D3 receptor levels are elevated in Parkinson's patients with ICD. We also did not find ICD-related abnormalities in D2 receptor levels. Our findings argue against the possibility that differences in D2/3 receptor levels can account for the development of ICD in PD; however, we cannot rule out that differences in dopamine levels (particularly in ventral striatum) may be involved.

    Abstract To systematically review and meta-analyze the outcome of Hodgkin lymphoma patients with a posttreatment (18)F-fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET)-negative residual mass. A systematic PubMed/MEDLINE database search was performed. The methodological quality of included studies was assessed. The number of patients with a posttreatment non-FDG-avid residual mass and the number of these patients who developed disease relapse during follow-up were extracted from each included study. Heterogeneity in disease relapse proportions across individual studies was assessed using the I2 test, with heterogeneity defined as I(2) > 50%. Using a Freeman-Tukey transformation, the disease relapse proportions from each individual study were then meta-analyzed with either a fixed-effects model (if I2 ≤ 50 %) or a random-effects model (if I2 > 50 %). A total of 5 studies comprising a total of 727 Hodgkin lymphoma patients with an FDG-PET-negative residual mass after first-line therapy were included. The overall quality of included studies was moderate. The proportion of patients with a posttreatment non-FDG-avid residual mass who experienced disease relapse during follow-up ranged between 0% and 13.8%. There was heterogeneity in disease relapse proportions across individual studies (I2 = 61.4%). Pooled disease relapse proportion (random effects) was 6.8% (95% confidence interval: 2.6%-12.5%). The disease relapse rate in Hodgkin lymphoma patients with a FDG-PET-negative residual mass after first-line therapy is approximately 6.8%. Considering the existing literature, the presence of a non-FDG-avid residual mass has not been proven yet to be associated with a worse outcome than a posttreatment FDG-PET-based complete remission status without a residual mass.

    Abstract Reactivation of endogenous retroviruses (ERVs), the relics of ancient infections, has been implicated in a number of disease contexts. In this issue of Cell, Liu et al. show how reactivation of ERVs in old age can induce senescence. This awakening of ERVs is associated with their epigenetic derepression and contributes to age-associated chronic inflammation.

    Abstract Epigenetic modifications are known to be crucial for hematopoietic stem cell (HSC) differentiation, with the BET family member BRD4 playing a vital role in this as an epigenetic reader. In this issue of EMBO reports, Yang et al (2023) demonstrate that the absence of BRD4 leads to senescence in HSCs and hematopoietic progenitor cells (HPCs), affecting the expression of crucial genes involved in myeloid and erythroid development. These data suggest that BRD4 has a protective role in preserving histone tails, thereby sustaining normal HSC/HPC functions.

    Abstract Rationale: Accurate diagnosis of head and neck paragangliomas is often complicated by biochemical silence and lack of catecholamine-associated symptoms, making accurate anatomical and functional imaging techniques essential to the diagnostic process.
    Methods: Ten patients (seven SDHD, three SDHB), with a total of 26 head and neck paragangliomas, were evaluated with anatomical and functional imaging. This study compares five different functional imaging techniques [(18)F-fluorodihydroxyphenylalanine ((18)F-FDOPA) positron emission tomography (PET), (18)F-fluorodopamine ((18)F-FDA) PET/computed tomography (CT), (18)F-fluoro-2-deoxy-D-glucose ((18)F-FDG) PET/CT, (123)I-metaiodobenzylguanidine ((123)I-MIBG) scintigraphy, and (111)In-pentetreotide scintigraphy] in the localization of head and neck paragangliomas.
    Results: Prospectively (18)F-FDOPA PET localized 26 of 26 lesions in the 10 patients, CT/magnetic resonance imaging localized 21 of 26 lesions, (18)F-FDG PET/CT localized 20 of 26 lesions, (111)In-pentetreotide scintigraphy localized 16 of 25 lesions, (18)F-FDA PET/CT localized 12 of 26 lesions, and (123)I-MIBG scintigraphy localized eight of 26 lesions. Differences in imaging efficacy related to genetic phenotype, even in the present small sample size, included the negativity of (18)F-FDA PET/CT and (123)I-MIBG scintigraphy in patients with SDHB mutations and the accuracy of (18)F-FDG PET/CT in all patients with SDHD mutations, as compared with the accuracy of (18)F-FDG PET/CT in only one patient with an SDHB mutation.
    Conclusion: Overall, (18)F-FDOPA PET proved to be the most efficacious functional imaging modality in the localization of SDHx-related head and neck paragangliomas and may be a potential first-line functional imaging agent for the localization of these tumors.

    Abstract Posttransplantation lymphoproliferative disorder (PTLD) is a histologic heterogeneous disease that complicates 4 to 8% of lung transplant recipients. Disease extent is an important prognostic factor and may affect therapy. Positron emission tomography with fluoro-2-deoxy-D-glucose (FDG-PET) has proven useful for staging high-grade lymphomas but is less accurate for staging low-grade and extranodal lymphoma. This study examined our initial experience using FDG-PET imaging to stage lung transplant recipients with posttransplantation lymphoproliferative disorder. FDG can show foci of uptake, particularly in extrathoracic sites, not seen by conventional imaging, which allows more accurate staging of disease thereby yielding useful prognostic information and guiding therapy.
