Abstract
BACKGROUND Degeneration of the locus coeruleus (LC) noradrenergic system contributes to clinical symptoms in Alzheimer's disease (AD) and Parkinson's disease (PD). Diffusion magnetic resonance imaging (MRI) has the potential to evaluate the integrity of the LC noradrenergic system. The aim of the current study was to determine whether the diffusion MRI-measured integrity of the LC and its tracts are sensitive to noradrenergic degeneration in AD and PD. METHODS Post-mortem in situ T1-weighted and multi-shell diffusion MRI was performed for 9 AD, 14 PD, and 8 control brain donors. Fractional anisotropy (FA) and mean diffusivity were derived from the LC, and from tracts between the LC and the anterior cingulate cortex, the dorsolateral prefrontal cortex (DLPFC), the primary motor cortex (M1) or the hippocampus. Brain tissue sections of the LC and cortical regions were obtained and immunostained for dopamine-beta hydroxylase (DBH) to quantify noradrenergic cell density and fiber load. Group comparisons and correlations between outcome measures were performed using linear regression and partial correlations. RESULTS The AD and PD cases showed loss of LC noradrenergic cells and fibers. In the cortex, the AD cases showed increased DBH + immunoreactivity in the DLPFC compared to PD cases and controls, while PD cases showed reduced DBH + immunoreactivity in the M1 compared to controls. Higher FA within the LC was found for AD, which was correlated with loss of noradrenergic cells and fibers in the LC. Increased FA of the LC-DLPFC tract was correlated with LC noradrenergic fiber loss in the combined AD and control group, whereas the increased FA of the LC-M1 tract was correlated with LC noradrenergic neuronal loss in the combined PD and control group. The tract alterations were not correlated with cortical DBH + immunoreactivity. CONCLUSIONS In AD and PD, the diffusion MRI-detected alterations within the LC and its tracts to the DLPFC and the M1 were associated with local noradrenergic neuronal loss within the LC, rather than noradrenergic changes in the cortex.

Abstract
Regional differences in synaptic degeneration may underlie differences in clinical presentation and neuropathological disease progression in Parkinson's Disease (PD) and Dementia with Lewy bodies (DLB). Here, we mapped and quantified synaptic degeneration in cortical brain regions in PD, PD with dementia (PDD) and DLB, and assessed whether regional differences in synaptic loss are linked to axonal degeneration and neuropathological burden. We included a total of 47 brain donors, 9 PD, 12 PDD, 6 DLB and 20 non-neurological controls. Synaptophysin+ and SV2A+ puncta were quantified in eight cortical regions using a high throughput microscopy approach. Neurofilament light chain (NfL) immunoreactivity, Lewy body (LB) density, phosphorylated-tau and amyloid-β load were also quantified. Group differences in synaptic density, and associations with neuropathological markers and Clinical Dementia Rating (CDR) scores, were investigated using linear mixed models. We found significantly decreased synaptophysin and SV2A densities in the cortex of PD, PDD and DLB cases compared to controls. Specifically, synaptic density was decreased in cortical regions affected at Braak α-synuclein stage 5 in PD (middle temporal gyrus, anterior cingulate and insula), and was additionally decreased in cortical regions affected at Braak α-synuclein stage 4 in PDD and DLB compared to controls (entorhinal cortex, parahippocampal gyrus and fusiform gyrus). Synaptic loss associated with higher NfL immunoreactivity and LB density. Global synaptophysin loss associated with longer disease duration and higher CDR scores. Synaptic neurodegeneration occurred in temporal, cingulate and insular cortices in PD, as well as in parahippocampal regions in PDD and DLB. In addition, synaptic loss was linked to axonal damage and severe α-synuclein burden. These results, together with the association between synaptic loss and disease progression and cognitive impairment, indicate that regional synaptic loss may underlie clinical differences between PD and PDD/DLB. Our results might provide useful information for the interpretation of synaptic biomarkers in vivo.

Abstract
BACKGROUND Motor and cognitive impairment in Parkinson's disease (PD) is associated with dopaminergic dysfunction that stems from substantia nigra (SN) degeneration and concomitant α-synuclein accumulation. Diffusion magnetic resonance imaging (MRI) can detect microstructural alterations of the SN and its tracts to (sub)cortical regions, but their pathological sensitivity is still poorly understood. OBJECTIVE To unravel the pathological substrate(s) underlying microstructural alterations of SN, and its tracts to the dorsal striatum and dorsolateral prefrontal cortex (DLPFC) in PD. METHODS Combining post-mortem in situ MRI and histopathology, T1-weighted and diffusion MRI, and neuropathological samples of nine PD, six PD with dementia (PDD), five dementia with Lewy bodies (DLB), and 10 control donors were collected. From diffusion MRI, mean diffusivity (MD) and fractional anisotropy (FA) were derived from the SN, and tracts between the SN and caudate nucleus, putamen, and DLPFC. Phosphorylated-Ser129-α-synuclein and tyrosine hydroxylase immunohistochemistry was included to quantify nigral Lewy pathology and dopaminergic degeneration, respectively. RESULTS Compared to controls, PD and PDD/DLB showed increased MD of the SN and SN-DLPFC tract, as well as increased FA of the SN-caudate nucleus tract. Both PD and PDD/DLB showed nigral Lewy pathology and dopaminergic loss compared to controls. Increased MD of the SN and FA of SN-caudate nucleus tract were associated with SN dopaminergic loss. Whereas increased MD of the SN-DLPFC tract was associated with increased SN Lewy neurite load. CONCLUSIONS In PD and PDD/DLB, diffusion MRI captures microstructural alterations of the SN and tracts to the dorsal striatum and DLPFC, which differentially associates with SN dopaminergic degeneration and Lewy neurite pathology. © 2023 The Authors.

Abstract
BACKGROUND Increased neurofilament levels in biofluids are commonly used as a proxy for neurodegeneration in several neurodegenerative disorders. In this study, we aimed to investigate the distribution of neurofilaments in the cerebral cortex of Parkinson's disease (PD), PD with dementia (PDD) and dementia with Lewy bodies (DLB) donors, and its association with pathology load and MRI measures of atrophy and diffusivity. METHODS Using a within-subject post-mortem MRI-pathology approach, we included 9 PD, 12 PDD/DLB and 18 age-matched control donors. Cortical thickness and mean diffusivity (MD) metrics were extracted respectively from 3DT1 and DTI at 3T in-situ MRI. After autopsy, pathological hallmarks (pSer129-αSyn, p-tau and amyloid-β load) together with neurofilament light-chain (NfL) and phosphorylated-neurofilament medium- and heavy-chain (p-NfM/H) immunoreactivity were quantified in seven cortical regions, and studied in detail with confocal-laser scanning microscopy. The correlations between MRI and pathological measures were studied using linear mixed models. RESULTS Compared to controls, p-NfM/H immunoreactivity was increased in all cortical regions in PD and PDD/DLB, whereas NfL immunoreactivity was increased in the parahippocampal and entorhinal cortex in PDD/DLB. NfL-positive neurons showed degenerative morphological features and axonal fragmentation. The increased p-NfM/H correlated with p-tau load, and NfL correlated with pSer129-αSyn but more strongly with p-tau load in PDD/DLB. Lastly, neurofilament immunoreactivity correlated with cortical thinning in PD and with increased cortical MD in PDD/DLB. CONCLUSIONS Taken together, increased neurofilament immunoreactivity suggests underlying axonal injury and neurofilament accumulation in morphologically altered neurons with increased pathological burden. Importantly, we demonstrate that such neurofilament markers at least partly explain MRI measures that are associated with the neurodegenerative process.

Abstract
Cognitive deficits in Alzheimer’s disease, specifically amnestic (memory dominant) deficits, are associated with cholinergic degeneration in the basal forebrain. The cholinergic nucleus within the basal forebrain, the nucleus basalis of Meynert, exhibits local atrophy and reduced cortical tract integrity on MRI, and reveals amyloid-β and phosphorylated-tau pathology at autopsy. To understand the pathophysiology of nucleus basalis of Meynert atrophy and its neocortical projections in Alzheimer’s disease, we used a combined post-mortem in situ MRI and histopathology approach. A total of 19 Alzheimer’s disease (10 amnestic and nine non-amnestic) and nine non-neurological control donors underwent 3 T T1-weighted MRI for anatomical delineation and volume assessment of the nucleus basalis of Meynert, and diffusion-weighted imaging for microstructural assessment of the nucleus and its projections. At subsequent brain autopsy, tissue dissection and immunohistochemistry were performed for amyloid-β, phosphorylated-tau and choline acetyltransferase. Compared to controls, we observed an MRI-derived volume reduction and altered microstructural integrity of the nucleus basalis of Meynert in Alzheimer’s disease donors. Furthermore, decreased cholinergic cell density was associated with reduced integrity of the nucleus and its tracts to the temporal lobe, specifically to the temporal pole of the superior temporal gyrus, and the parahippocampal gyrus. Exploratory post hoc subgroup analyses indicated that cholinergic cell density could be associated with cortical tract alterations in amnestic Alzheimer’s disease donors only. Our study illustrates that in Alzheimer’s disease, cholinergic degeneration in the nucleus basalis of Meynert may contribute to damaged cortical projections, specifically to the temporal lobe, leading to cognitive deterioration.

Abstract
Alzheimer’s disease is characterized by cortical atrophy on MRI and abnormal depositions of amyloid-beta, phosphorylated-tau and inflammation pathologically. However, the relative contribution of these pathological hallmarks to cortical atrophy, a widely used MRI biomarker in Alzheimer’s disease, is yet to be defined. Therefore, the aim of this study was to identify the histopathological correlates of MRI cortical atrophy in Alzheimer’s disease donors, and its typical amnestic and atypical non-amnestic phenotypes. Nineteen Alzheimer’s disease (of which 10 typical and 9 atypical) and 10 non-neurological control brain donors underwent post-mortem in situ 3T 3D-T1, from which cortical thickness was calculated with Freesurfer. Upon subsequent autopsy, 12 cortical brain regions from the right hemisphere and 9 from the left hemisphere were dissected and immunostained for amyloid-beta, phosphorylated-tau and reactive microglia, and percentage area load was calculated for each marker using ImageJ. In addition, post-mortem MRI was compared to ante-mortem MRI of the same Alzheimer’s disease donors when available. MRI-pathology associations were assessed using linear mixed models. Higher amyloid-beta load weakly correlated with higher cortical thickness globally (r = 0.22, P = 0.022). Phosphorylated-tau strongly correlated with cortical atrophy in temporal and frontal regions (−0.76 < r < −1.00, all P < 0.05). Reactive microglia load strongly correlated with cortical atrophy in the parietal region (r = −0.94, P < 0.001). Moreover, post-mortem MRI scans showed high concordance with ante-mortem scans acquired <1 year before death. In conclusion, distinct histopathological markers differently correlated with cortical atrophy, highlighting their different roles in the neurodegenerative process, and therefore contributing to the understanding of the pathological underpinnings of MRI atrophic patterns in Alzheimer’s disease. In our cohort, no or only subtle differences were found in MRI-pathology associations in Alzheimer’s disease phenotypes, indicating that the histopathological correlates of cortical atrophy in typical and atypical phenotypes might be similar. Moreover, we show that post-mortem in situ MRI can be used as proxy for ante-mortem in vivo MRI.

Abstract
Objective Multiple sclerosis (MS) is a chronic neuroinflammatory and neurodegenerative disease of unknown etiology. Although the prevalent view regards a CD4+‐lymphocyte autoimmune reaction against myelin at the root of the disease, recent studies propose autoimmunity as a secondary reaction to idiopathic brain damage. To gain knowledge about this possibility we investigated the presence of axonal and myelinic morphological alterations, which could implicate imbalance of axon‐myelin units as primary event in MS pathogenesis. Methods Using high resolution imaging histological brain specimens from patients with MS and non‐neurological/non‐MS controls, we explored molecular changes underpinning imbalanced interaction between axon and myelin in normal appearing white matter (NAWM), a region characterized by normal myelination and absent inflammatory activity. Results In MS brains, we detected blister‐like swellings formed by myelin detachment from axons, which were substantially less frequently retrieved in non‐neurological/non‐MS controls. Swellings in MS NAWM presented altered glutamate receptor expression, myelin associated glycoprotein (MAG) distribution, and lipid biochemical composition of myelin sheaths. Changes in tethering protein expression, widening of nodes of Ranvier and altered distribution of sodium channels in nodal regions of otherwise normally myelinated axons were also present in MS NAWM. Finally, we demonstrate a significant increase, compared with controls, in citrullinated proteins in myelin of MS cases, pointing toward biochemical modifications that may amplify the immunogenicity of MS myelin. Interpretation Collectively, the impaired interaction of myelin and axons potentially leads to myelin disintegration. Conceptually, the ensuing release of (post‐translationally modified) myelin antigens may elicit a subsequent immune attack in MS. ANN NEUROL 2021;89:711–725

Abstract
BACKGROUND The association between postoperative inflammatory markers and risk of complications after pancreaticoduodenectomy (PD) is controversial. We sought to assess the diagnostic value of perioperative C-reactive protein (CRP) and procalcitonin (PCT) levels in the early identification of patients at risk for complications after PD. METHODS In 2014, 84 patients undergoing elective PD were enrolled in a prospective database. Clinicopathological characteristics, CRP and PCT, as well as short-term outcomes, such as complications and pancreatic fistula, were analyzed. Complications and pancreatic fistula were defined based on the Clavien-Dindo classification and the International Study Group on Pancreatic Fistula (ISGPF) classification, respectively. High CRP and PCT were classified using cut-off values based on ROC curve analysis. RESULTS The majority (73.8 %) of patients had pancreatic adenocarcinoma. CRP and PCT levels over the first 5 postoperative days (POD) were higher among patients who experienced a complication versus those who did not (p < 0.001). Postoperative CRP and PCT levels were also higher among patients who developed a grade B or C pancreatic fistula (p < 0.05). A CRP concentration >84 mg/l on POD 1 (AUC 0.77) and >127 mg/l on POD 3 (AUC 0.79) was associated with the highest risk of overall complications (OR 6.86 and 9.0, respectively; both p < 0.001). Similarly patients with PCT >0.7 mg/dl on POD 1 (AUC 0.67) were at higher risk of developing a postoperative complication (OR 3.33; p = 0.024). On POD 1, a CRP >92 mg/l (AUC 0.72) and a PCT >0.4 mg/dl (AUC 0.70) were associated with the highest risk of pancreatic fistula (OR 5.63 and 5.62, respectively; both p < 0.05). CONCLUSIONS CRP and PCT concentration were associated with an increased risk of developing complications and clinical relevant pancreatic fistula after PD. Use of these biomarkers may help identify those patients at highest risk for perioperative morbidity and help guide postoperative management of patients undergoing PD.

Abstract
OBJECTIVES Serous cystic neoplasm (SCN) is a cystic neoplasm of the pancreas whose natural history is poorly known. The purpose of the study was to attempt to describe the natural history of SCN, including the specific mortality. DESIGN Retrospective multinational study including SCN diagnosed between 1990 and 2014. RESULTS 2622 patients were included. Seventy-four per cent were women, and median age at diagnosis was 58 years (16-99). Patients presented with non-specific abdominal pain (27%), pancreaticobiliary symptoms (9%), diabetes mellitus (5%), other symptoms (4%) and/or were asymptomatic (61%). Fifty-two per cent of patients were operated on during the first year after diagnosis (median size: 40 mm (2-200)), 9% had resection beyond 1 year of follow-up (3 years (1-20), size at diagnosis: 25 mm (4-140)) and 39% had no surgery (3.6 years (1-23), 25.5 mm (1-200)). Surgical indications were (not exclusive) uncertain diagnosis (60%), symptoms (23%), size increase (12%), large size (6%) and adjacent organ compression (5%). In patients followed beyond 1 year (n=1271), size increased in 37% (growth rate: 4 mm/year), was stable in 57% and decreased in 6%. Three serous cystadenocarcinomas were recorded. Postoperative mortality was 0.6% (n=10), and SCN's related mortality was 0.1% (n=1). CONCLUSIONS After a 3-year follow-up, clinical relevant symptoms occurred in a very small proportion of patients and size slowly increased in less than half. Surgical treatment should be proposed only for diagnosis remaining uncertain after complete workup, significant and related symptoms or exceptionally when exists concern with malignancy. This study supports an initial conservative management in the majority of patients with SCN. TRIAL REGISTRATION NUMBER IRB 00006477.

Abstract
INTRODUCTION Mucinous cystic neoplasm (MCN) and solid pseudopapillary neoplasm (SPN) of the pancreas are uncommon hormone-related pancreatic tumors (HRPTs) with a clear predominance in young women. This trial aims to investigate the possible association between HRPTs development in males and phenotypic and sex hormone alterations. METHODS We performed a retrospective analysis of our database between February 1990 and February 2012. Risk factors for sexual dysfunction were considered exclusion criteria. We investigated secondary sexual characteristics development, sex hormone level and overall sexual dysfunction degree according with the International Index of Erectile Function Questionnaire (IIEF). RESULTS We initially identified 25 patients [(MCN: n = 16 (64%); SPN: n = 9 (36%)]. At follow-up, 5 patients were lost, 8 resulted dead and 3 were excluded according to exclusion criteria. We finally enrolled 9 patients (MCN: n = 5; SPN: n = 4). Puberty occurred within physiological age for 7 patients, whereas it was delayed in 2 cases. Three patients revealed mild to moderate sexual dysfunction, along with low testosterone level in two cases. One patient presented hormonal alteration with a normal IIEF score. DISCUSSION In this study, the first in literature with similar aim, hormonal and/or sexual dysfunction was present in 4 out of 9 patients affected by HRPT. The rarity of these lesions makes further trials to be needed for reliable conclusions.

Abstract
BACKGROUND Radiofrequency ablation (RFA) is an emerging treatment for patients with locally advanced pancreatic carcinoma, and can be combined with radiochemotherapy and intra-arterial plus systemic chemotherapy. METHODS This observational study compared two groups of patients with locally advanced pancreatic carcinoma treated with either primary RFA (group 1) or RFA following any other primary treatment (group 2). RESULTS Between February 2007 and May 2010, 107 consecutive patients were treated with RFA. There were 47 patients in group 1 and 60 in group 2. Median overall survival was 25·6 months. Median overall survival was significantly shorter in group 1 than in group 2 (14·7 versus 25·6 months; P = 0·004) Patients treated with RFA, radiochemotherapy and intra-arterial plus systemic chemotherapy (triple-approach strategy) had a median overall survival of 34·0 months. CONCLUSION RFA after alternative primary treatment was associated with prolonged survival. This was further extended by use of a triple-approach strategy in selected patients. Further evaluation of this approach seems warranted.

Abstract
BACKGROUND : Radiofrequency ablation (RFA) may be a valuable treatment option for locally advanced pancreatic cancer. The present study examined its feasibility and safety. METHODS : Fifty patients with locally advanced pancreatic cancer were studied prospectively. Ultrasound-guided RFA was performed during laparotomy. The main outcome measures were short-term morbidity and mortality. RESULTS : The tumour was located in the pancreatic head or uncinate process in 34 patients and in the body or tail in 16; median diameter was 40 (interquartile range 30-50) mm. RFA was the only treatment in 19 patients. RFA was combined with biliary and gastric bypass in 19 patients, gastric bypass alone in eight, biliary bypass alone in three and pancreaticojejunostomy in one. The 30-day mortality rate was 2 per cent. Abdominal complications occurred in 24 per cent of patients; in half they were directly associated with RFA and treated conservatively. Three patients with surgery-related complications needed reoperation. Reduction of RFA temperature from 105 degrees C to 90 degrees C resulted in a significant reduction in complications (ten versus two of 25 patients; P = 0.028). Median postoperative hospital stay was 10 (range 7-31) days. CONCLUSION : RFA of locally advanced pancreatic cancer is feasible and relatively well tolerated, with a 24 per cent complication rate.

Abstract
Twenty percent of all acute pancreatitis patients present with necrotizing pancreatitis. Infected necrosis is responsible for 80% of deaths in the course of the disease though, thanks to antibiotic prophylaxis, the infection rate is decreasing. When infection occurs, the prognosis is poor, and the need for debridement and drainage of the necrosis is mandatory. The aim of this study was to review the most recent literature in order to present an update of open surgical management of infected necrosis.

Abstract
Because the mortality of severe pancreatitis is higher when infected necrosis supervenes, prevention of infections has become a relevant endpoint for management. The "ideal" drug should be characterized by specific activity against the bacteria known to be responsible for infection and should be able to penetrate the gland in a sufficient concentration. To date there have been eight prospective trials with antibiotics, one on selective digestive decontamination, and others with enteral nutrition. A meta-analysis regarding experiences with antimicrobial drugs reports a significant reduction in the incidence of infected necrosis and pancreatic abscesses during severe pancreatitis. In conclusion, among the several options aimed at reducing infections during necrotizing pancreatitis, the prophylactic use of antibacterial drugs is the only one to have been tested to date in several randomized studies. Strong consideration should be given to treating patients with severe pancreatitis with broadspectrum antibiotics, selective digestive decontamination, and enteral nutrition.

Abstract
The middle pancreatic resection for benign pathology of the pancreas has been proposed as an advantageous alternative to the distal pancreatectomy, even though the risk of complications is greater. The purpose of the present study is to compare the cost and intra and perioperative impact for the 2 procedures. All patients with benign neoplasia of the body and tail of the pancreas operated on from 1990-1999 were selected from our computer archives, 21 patients underwent an intermediate resection and 64 a distal pancreatectomy. Operative time, units transfused, perioperative complications, post-operative stay and cost were compared. Statistical analysis revealed that the 2 operations are not significantly different in the intra-operative period. Comparing serious complications, the percentage of pancreatic fistulas (33% vs. 11%; P < 0.03) and average hospital stay (21.2 +/- 11.7 days vs. 15.5 +/- 7.1 days; p = 0.009) are greater for the middle than distal resection, respectively. In cases with post-operative complications the hospital stay is even more significant (middle 31.8 +/- 10.3 days vs. 19.1 +/- 7.6 days; p = 0.0002). The economic margin of residual costs, calculated by using the difference of DRG (no 192) and average post-operative costs, is similar for the 2 procedures in cases with normal post-operative courses, (intermediate Euro 2890.02; distal Euro 3181.9), while in cases with complications (DRG no 191), the difference increases (intermediate Euro 8670.11; distal Euro 12788.94). The middle pancreatic resection in respect to the distal pancreatectomy presents a greater technical difficulty when you take into account the longer post-operative course, the increased difficulty in treating complications and the increased costs.

Abstract
Quality of life (Qol) assessment is a mandatory endpoint of cancer clinical trials. Little research has been conducted on pancreatic cancer (Pc) and no disease specific Qol questionnaire exists. We report on the development of the European Organization for Research and Treatment of Cancer (EORTC) Pc Qol module to supplement the core cancer module (QLQ-C30). Literature research and qualitative interviews with 6 specialists and 34 patients in the UK were followed by construction of a questionnaire, a peer review by international specialists and EORTC. Administration of the QLQ-C 30, a provisional Pc module and a qualitative debriefing interview was performed on 78 patients in 8 countries stratified into groups by disease stage and treatment intention. Pretesting identified that 23/26 questions had an adequate internal reliability (Cronbach's alpha > 0.7) and construct validity (Pearson's r 0.4-0.6). The median time of completion was 12 mins. Qualitative analysis indicates that the module is easy to complete and cross culturally applicable. The EORTC QLO-PAN 26 includes 26 items covering symptoms, body image, sexuality and the emotional and social consequences of Pc. It is intended for use in patients undergoing clinical trials for pancreatic cancer including surgery, chemotherapy and radiotherapy and will allow the detection of small but clinically meaningful differences in clinical trials for Pc.
