The hidden side of migration: Understanding sexuality as an aspiration to migrate

Sexuality is an understated yet increasingly important motive for migration. Motivation to migrate is often viewed from a polarized lens, either as the pursuit of economic security or as a desire to access to human rights, on which social policy on migration has been predicated. We introduce the notion of the toxic triangle to account for contexts that prove hostile to freedom of sexuality and trigger individuals to migrate. Drawing on insights from 25 interviews, we demonstrate how sexuality remains a silent yet significant contributor to individuals' decisions to migrate from an adversarial context. We illustrate how the participants fall into four archetypes of dreamers, climbers, escapists, and seekers, based on their endowments and experiences of sexuality and gender identity as salient sources of their motivation to migrate. Focusing on the hidden side of Turkish migration to the UK o..ers insights into how the pursuit of freedom of sexuality in terms of safety and security shapes motivations and experiences of migration across two cultures

The design and fabrication of supramolecular semiconductor nanowires formed by benzothienobenzothiophene (BTBT)-conjugated peptides

π-Conjugated small molecules based on a [1]benzothieno[3,2-b]benzothiophene (BTBT) unit are of great research interest in the development of solution-processable semiconducting materials owing to their excellent charge-transport characteristics. However, the BTBT π-core has yet to be demonstrated in the form of electro-active one-dimensional (1D) nanowires that are self-assembled in aqueous media for potential use in bioelectronics and tissue engineering. Here we report the design, synthesis, and self-assembly of benzothienobenzothiophene (BTBT)–peptide conjugates, the BTBT–peptide (BTBT-C3–COHN-Ahx-VVAGKK-Am) and the C8-BTBT–peptide (C8-BTBT-C3–COHN-Ahx-VVAGKK-Am), as β-sheet forming amphiphilic molecules, which self-assemble into highly uniform nanofibers in water with diameters of 11–13(±1) nm and micron-size lengths. Spectroscopic characterization studies demonstrate the J-type π–π interactions among the BTBT molecules within the hydrophobic core of the self-assembled nanofibers yielding an electrical conductivity as high as 6.0 × 10−6 S cm−1. The BTBT π-core is demonstrated, for the first time, in the formation of self-assembled peptide 1D nanostructures in aqueous media for potential use in tissue engineering, bioelectronics and (opto)electronics. The conductivity achieved here is one of the highest reported to date in a non-doped state

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

The Comparison of Premature Ejaculation Assessment Questionnaires and Their Sensitivity for the Four Premature Ejaculation Syndromes: Results from the Turkish Society of Andrology Sexual Health Survey

WOS: 000289115400026PubMed ID: 21269396Introduction. In addition to the previously defined "lifelong" and "acquired" premature ejaculation (PE), the existence of two more subtypes of PE, namely "natural variable PE" and "premature-like ejaculatory dysfunction," has been proposed. Aims. To evaluate the diagnostic value of the Premature Ejaculation Diagnostic Tool (PEDT) and Arabic Index of Premature Ejaculation (AIPE) in a population-based study, in relation to their sensitivity across these four different PE syndromes and to assess the Premature Ejaculation Profile (PEP) scores of patients with lifelong, acquired, natural variable PE and premature-like ejaculatory dysfunction. Methods. Between June 2009 and December 2009, couples were randomly selected from 17 provinces of Turkey. Subjects with the complaint of ejaculating prematurely were classified as lifelong, acquired, natural variable PE, and premature-like ejaculatory dysfunction according to the medical and sexual history they described. PE status was also assessed with PEDT, AIPE and PEP. The sensitivity, specificity, positive predictive value and negative predictive value were calculated for PEDT and AIPE in the study population whereas detection rates of these two questionnaires were also compared among the four PE syndromes. Moreover, PEP scores of patients with lifelong, acquired, natural variable PE and premature-like ejaculatory dysfunction were compared. Significance level was considered as P < 0.05. Main Outcome Measures. Scores obtained from PEDT, AIPE, and PEP questionnaires. Results. A total of 2,593 couples were enrolled where 512 (20.0%) male subjects reported PE. PEDT, AIPE, and PEP measures of the PE patients indicated worse sexual function (P < 0.001 each). Mean scores obtained from questionnaires were significantly better in patients with premature-like ejaculatory dysfunction and they were the worst in patients with acquired PE (P < 0.001 each). The sensitivity values of PEDT and AIPE were 89.3 and 89.5, whereas their specificity values were 50.5 and 39.1, respectively. There were statistically significant differences in detection rates of PEDT and AIPE among the four PE syndromes (P = 0.006 and P < 0.001). They were higher in acquired and lifelong PE and lower in premature-like ejaculatory dysfunction. Conclusion. PEDT and AIPE can diagnose PE with high sensitivity, especially in patients with lifelong and acquired PE. The complaint of patients with acquired PE seems to be more severe than those complaining of lifelong, natural variable PE and premature-like ejaculatory dysfunction patients.

RhoA/Rho-kinase suppresses endothelial nitric oxide synthase in the penis: A mechanism for diabetes-associated erectile dysfunction

Significant impairment in endothelial-derived nitric oxide is present in the diabetic corpus cavernosum. RhoA/Rho-kinase may suppress endothelial nitric oxide synthase (eNOS). Here, we tested the hypothesis that RhoA/Rho-kinase contributes to diabetes-related erectile dysfunction and down-regulation of eNOS in the streptozotocin (STZ)-diabetic rat penis. Colocalization of Rho-kinase and eNOS protein was present in the endothelium of the corpus cavernosum. RhoA/Rho-kinase protein abundance and MYPT-1 phosphorylation at Thr-696 were elevated in the STZ-diabetic rat penis. In addition, eNOS protein expression, cavernosal constitutive NOS activity, and cGMP levels were reduced in the STZ-diabetic penis. To assess the functional role of RhoA/Rho-kinase in the penis, we evaluated the effects of an adeno-associated virus encoding the dominant-negative RhoA mutant (AAVTCMV19NRhoA) on RhoA/Rho-kinase and eNOS and erectile function in vivo in the STZ-diabetic rat. STZ-diabetic rats transfected with AAVCMVT19NRhoA had a reduction in RhoA/Rho-kinase and MYPT-1 phosphorylation at a time when cavernosal eNOS protein, constitutive NOS activity, and cGMP levels were restored to levels found in the control rats. There was a significant decrease in erectile response to cavernosal nerve stimulation in the STZ-diabetic rat. AAVT19NRhoA gene transfer improved erectile responses in the STZ-diabetic rat to values similar to control. These data demonstrate a previously undescribed mechanism for the down-regulation of penile eNOS in diabetes mediated by activation of the RhoA/Rho-kinase pathway. Importantly, these data imply that inhibition of RhoA/Rho-kinase improves eNOS protein content and activity thus restoring erectile function in diabetes
