    Abstract Sigma-1 receptor (σ-1R) modulates cellular signaling pathways, probably acting as a ligand operated chaperone. When activated, the receptor translocates from the interface mitochondrion associated membrane of the endoplasmic reticulum to the cell membrane. σ-1R was demonstrated in some brain regions, including the pineal gland, and was proposed to be involved in several cerebral processes, including neuroprotective responses against homeostasis alterations. On this basis, the immunohistochemical expression of σ-1R in human pineal glands was evaluated, with particular regard to the different causes of death. Thirty-eight pineal glands obtained from forensic autopsies were divided into five groups according to the cause of death: sudden death, drowning, fire fatality, hanging, and hemorrhagic shock, and examined with hematoxylin-eosin stain and immunohistochemistry for σ-1R. Both pinealocytes and perivascular spaces were evaluated. The pineal glands from sudden death were only mildly positive for σ-1R, while a more evident immunopositivity was observed in hanging, fire fatality, hemorrhagic shock, and drowning. These results were confirmed in a two-by-two comparison between the sudden death group and other groups. Our data demonstrate for the first time with immunohistochemical techniques the presence of σ-1R expression in the human pineal gland and propose a direct correlation between σ-1R expression and duration of the death process, in particular when hypoxic conditions and/or excessive psychological stress are present.

    Abstract Objectives: The goal was to evaluate the accuracy of preoperative histological assessment and the factors affecting the accuracy and the subsequent effect on postoperative survival after surgical treatment for malignant pleural mesothelioma (MPM).
    Methods: We analysed the perioperative course of patients who underwent surgery for MPM in a single institution over a 5-year period. The primary end point was to evaluate the proportion of histological discordance between preoperative assessment and postoperative histological diagnosis. The secondary end point was to evaluate its prognostic effect on postoperative survival after surgical treatment.
    Results: One-hundred and twenty-nine patients were included in this study. Histological discordance between preoperative assessment and postoperative histological diagnosis was found in 27 of 129 patients (20.9%): epithelial to biphasic/sarcomatoid (negative discordance) in 24 and biphasic to epithelial (positive discordance) in 3 (P-value < 0.001). All 24 patients who exhibited epithelial-to-mesenchymal transition (EMT) had received neoadjuvant chemotherapy (P-value: 0.006). In the 34 patients who underwent upfront surgery, only 1 case (2.9%) of EMT was identified (P-value: 0.127). EMT was not associated with a less invasive method of biopsy (P-value: 0.058) or with the volume or maximum diameter of the biopsy (P-value: 0.358 and 0.518, respectively), but it was significantly associated with the receipt of neoadjuvant chemotherapy (P-value: 0.006). At a median follow-up of 17 months (IQR: 11.0-28.0), 50 (39%) patients are still alive. Overall survival was significantly reduced in those patients who received neoadjuvant chemotherapy and who exhibited discordance (EMT) compared to those who did not: 11 (95% CI: 6.2-15.8) months versus 19 (95% CI: 14.2-23.8) months (P-value < 0.001). In addition, there was no difference in overall survival between those who received neoadjuvant chemotherapy and those who had upfront surgery: 16 (95% CI: 2.5-19.5) months versus 30 (95% CI: 11.6-48.4) months (P-value: 0.203).
    Conclusions: The association of neoadjuvant chemotherapy with perioperative histological discordance can be explained by EMT, which leads to worse survival. Therefore, there is an argument for the preferential use of upfront surgery in the treatment of otherwise resectable MPM.

    Abstract Background: The accepted aim of radical surgery for malignant pleural mesothelioma (MPM) is the achievement of macroscopic complete resection (MCR) whilst reducing perioperative morbidity by preserving normal tissue. Whilst preservation of the lung by pleurectomy/decortication (PD) has become widely utilised, there remains debate regarding the management of the diaphragm. Muscle-sparing complete excision of the diaphragmatic pleura is technically challenging; thus, surgeons may proceed to extended PD with phrenectomy and possible increased morbidity or to preserve the diaphragmatic pleura at the expense of MCR with potential survival deficit. We aimed to evaluate the effects of an intentional change in protocol to diaphragm-sparing PD whilst maintaining MCR as the treatment of choice for MPM.
    Methods: In a series of 136 patients (111M:25F, median age 68(63-73) years) undergoing radical surgery for MPM, we identified 28 patients (22M:6F, median age 67(60-71) years) in whom MCR was achieved without phrenectomy (PD group). We compared their perioperative outcomes and survival with a historical control group of 18 patients (18M:0F, median age 69(57-78) years) in whom MCR had been achieved with phrenectomy (EPD group) but in whom there was no histological evidence of diaphragm muscle invasion and who, in retrospect, could have undergone muscle-sparing MCR if this procedure had been attempted.
    Results: There was no significant intergroup difference in demographics or tumour cell type; the majority of both groups were found to be epithelial (PD 85.7%, EPD 77.8%). The EPD group was found to be more locally advanced (T3 55.56%) than the PD group (T1 46.43%) (
    Conclusions: A surgical strategy of attempting to spare the diaphragm whilst still achieving MCR wherever possible is justified by improved perioperative outcomes without compromising OS.
