Psychological Distress in Erectile Dysfunction : The Moderating Role of Attachment

Introduction: In clinical consultations, men with erectile dysfunction do not always express personal, sexual, and interpersonal concerns. Aim: We explore whether the attenuated impact of erectile dysfunction may be explained by a regulation of negative affect that causes activation of the attachment system. Methods: The study sample consisted of 69 men diagnosed with erectile dysfunction, mean (SD) age 56 (10.83) years. Participants completed self-reported questionnaires to assess erectile dysfunction severity, attachment style, sexual satisfaction, relationship satisfaction, and psychological symptoms. Main Outcome Measure: The moderating role of attachment between erectile dysfunction and sexual satisfaction, relationship satisfaction, and psychological distress was evaluated using multiple linear regression and moderation analysis. Results: All men in the sample had high attachment avoidance, distributed between the dismissive-avoidant (69.6%) and fearful-avoidant (30.4%) substyles, but low levels of psychological symptoms. Despite their erectile dysfunction, 27 patients (39.1%) rated their sexual life as satisfactory, and 46 (66.7%) rated their relationship with their partner as satisfactory. Men with fearful-avoidant attachment reported feeling more sexual desire and less sexual satisfaction than men with dismissive-avoidant attachment. Multiple linear regression analysis showed that sexual satisfaction variance was explained by erectile dysfunction severity, attachment anxiety, and relationship satisfaction scores. Moderation analysis showed that attachment anxiety, but not relationship satisfaction, moderated the impact of erectile dysfunction on sexual satisfaction. Conclusion: The avoidance dimension of attachment, which tends to be high in patients with erectile dysfunction, involves deactivation of the sexual system in an effort to minimize the emotional distress associated with erectile dysfunction, which damages sexual and relationship intimacy and delays the decision to obtain professional help. The presence of high attachment avoidance and the moderating value of attachment anxiety allow us to propose specific treatments for these men.

Anterior cruciate ligament reconstruction: A multicenter prospective cohort study evaluating 3 different grafts using same bone drilling method

To compare the clinical outcomes after anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone autograft (BPTBAu), BPTB allograft (BPTBAll), or hamstring (semitendinosus-gracilis) tendon autograft (HTAu), performing bone drilling with same methods in terms of transtibial drilling, orientation, positioning, and width of femoral and tibial tunnels. DESIGN: Multicenter prospective cohort study (level of evidence II). SETTING: Departments of Orthopedic Surgery of Centro Medico Teknon (Barcelona, Spain) Clinica Universitaria de Navarra (Navarra, Spain), and Clinica FREMAP (Gijon, Spain). PATIENTS: All patients with ACL tears attending 3 different institutions between January 2004 and June 2006 were approached for eligibility and those meeting inclusion criteria finally participated in this study. INTERVENTION: Each institution was assigned to perform a specific surgical technique. Patients were prospectively followed after undergoing ACL reconstruction with BPTBAu, BPTBAll, or HTAu, with a minimum follow-up of 24 months. MAIN OUTCOME MEASURES: Included knee laxity and International Knee Documentation Committee (IKDC) score. Knee laxity was assessed with the KT-1000 arthrometer (evaluated with neutral and external rotation positions) and both Lachman and pivot shift tests. Additional outcomes included main symptoms (anterior knee pain, swelling, crepitation, and instability), disturbance in knee sensation, visual analogue scale (VAS) for satisfaction with surgery, range of motion (ROM), and isokinetic knee strength. RESULTS: There were no significant differences among the 3 groups for any of the clinical outcomes, except for a slightly greater KT-1000-measured knee laxity in external rotation in the BPTBAu compared with the other groups. All patients demonstrated grade A or B of the IKDC. The mean VAS for satisfaction with surgery in all patients was 8.5. CONCLUSIONS: The selection of the surgical technique for ACL reconstruction may be based on the surgeon's preference

Gas and seismicity within the Istanbul seismic gap

Understanding micro-seismicity is a critical question for earthquake hazard assessment. Since the devastating earthquakes of Izmit and Duzce in 1999, the seismicity along the submerged section of North Anatolian Fault within the Sea of Marmara (comprising the “Istanbul seismic gap”) has been extensively studied in order to infer its mechanical behaviour (creeping vs locked). So far, the seismicity has been interpreted only in terms of being tectonic- driven, although the Main Marmara Fault (MMF) is known to strike across multiple hydrocarbon gas sources. Here, we show that a large number of the aftershocks that followed the M 5.1 earthquake of July, 25th 2011 in the western Sea of Marmara, occurred within a zone of gas overpressuring in the 1.5–5 km depth range, from where pressurized gas is expected to migrate along the MMF, up to the surface sediment layers. Hence, gas-related processes should also be considered for a complete interpretation of the micro- seismicity (~M < 3) within the Istanbul offshore domain

Measurement of the neutron flux at the Canfranc Underground Laboratory with HENSA

We have performed a long-term measurement of the neutron flux with the High Efficiency Neutron Spectrometry Array HENSA in the Hall A of the Canfranc Underground Laboratory. The Hall A measurement campaign lasted from October 2019 to March 2021, demonstrating an excellent stability of the HENSA setup. Preliminary results on the neutron flux from this campaign are presented for the first time. In Phase 1 (113 live days) a total neutron flux of 1.66(2) $\times$10$^{-5}$ cm$^{-2}$ s$^{-1}$ is obtained. Our results are in good agreement with those from our previous shorter measurement where a reduced experimental setup was employed.Comment: Proceedings of the 17th International Conference on Topics in Astroparticle and Underground Physics (TAUP 2021

Long-term evolution of the neutron rate at the Canfranc Underground Laboratory

We report results on the long-term variation of the neutron counting rate at the Canfranc Underground Laboratory, of importance for several low-background experiments installed there, including rare-event searches. The measurement campaign was performed employing the High Efficiency Neutron Spectrometry Array (HENSA) mounted in Hall A and lasted 412 live days. The present study is the first long-term measurement of the neutron rate with sensitivity over a wide range of neutron energies (from thermal up to 0.1 GeV and beyond) performed in any underground laboratory so far. Data on the environmental variables inside the experimental hall (radon concentration, air temperature, air pressure and humidity) were also acquired during all the measurement campaign. We have investigated for the first time the evolution of the neutron rate for different energies of the neutrons and its correlation with the ambient variables.Comment: 12 pages, 5 figures, 2 table

ZZW-115-dependent inhibition of NUPR1 nuclear translocation sensitizes cancer cells to genotoxic agents

Establishing the interactome of the cancer-associated stress protein Nuclear Protein 1 (NUPR1), we found that it binds to several hundreds of proteins, including proteins involved in nuclear translocation, DNA repair, and key factors of the SUMO pathway. We demonstrated that the NUPR1 inhibitor ZZW-115, an organic synthetic molecule, competes with importins for the binding to the NLS region of NUPR1, thereby inhibiting its nuclear translocation. We hypothesized, and then proved, that inhibition of NUPR1 by ZZW-115 sensitizes cancer cells to DNA damage induced by several genotoxic agents. Strikingly, we found that treatment with ZZW-115 reduced SUMOylation of several proteins involved in DNA damage response (DDR). We further report that the presence of recombinant NUPR1 improved the SUMOylation in a cell-free system, indicating that NUPR1 directly stimulates the SUMOylation machinery. We propose that ZZW-115 sensitizes cancer cells to genotoxic agents by inhibiting the nuclear translocation of NUPR1 and thereby decreasing the SUMOylation-dependent functions of key proteins involved in the DDR
