Abstract	This article considers the potential payoffs of the diasporic as an analytical category developed from Indian Ocean histories that are related to and distinct from various castings of the global. Historically tracing the Indian Ocean trajectories of a Sufi Muslim family from Hadhramawt in relation to changing terms of sovereignty from the late-eighteenth century through the interwar period, the contours and crises of a normative framework for collective and individual life are recuperated and reexamined. The history of these individuals and the theory of life they presuppose and at times explicitly predicate or oppose afford the historian a view of the diasporic as capable of materializing the simultaneity of this- and other-worldly modes of existence. The article concludes that mystical interruptions of historical time that a critical diasporic lens again makes legible as an enduring global form of life represent rarely appreciated sites of emancipation.

Abstract	Introduction: In recent years, major findings on concomitant procedures and anticoagulation management have occurred in Mitral Valve (MV) surgery. Therefore, we sought to evaluate the current practices in MV interventions across Europe. Methods: In October 2021, all national cardio-thoracic societies in the European region were identified following an electronic search and sent an online survey of 14 questions to distribute among their member consultant/attending cardiac surgeons. Results: The survey was completed by 91 consultant/attending cardiac surgeons across 12 European countries, with 78% indicating MV repair as their specialty area. 57.1% performed >150 operations/year and 71.4% had 10+ years of experience.Concomitant tricuspid valve repair is performed for moderate tricuspid regurgitation (TR) by 69% of surgeons and for mild TR by 26.3%, both with annular diameter >40 mm. 50.6% indicated ischaemic MV surgery in patients undergoing CABG if moderate mitral regurgitation with ERO >20 mm Conclusion: These results demonstrate a variable practice for MV surgery, and a degree of lack of compliance with surgical intervention guidelines and anticoagulation strategy.

Abstract	Study Design This was a retrospective cohort study. Purpose This study investigated the influence of preoperative mental health on patient-reported outcome measures (PROMs) and minimal clinically important difference (MCID) among workers’ compensation (WC) recipients undergoing minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). Overview of Literature No studies have evaluated the impact of preoperative mental functioning on outcomes following MIS TLIF among WC claimants. Methods WC recipients undergoing single-level MIS TLIF were identified. PROMs of Visual Analog Scale (VAS) for back and leg pain, Oswestry Disability Index (ODI), 12-item Short Form Physical and Mental Composite Scale (SF-12 PCS/MCS), and Patient-Reported Outcomes Measurement Information System Physical Function evaluated subjects preoperatively/postoperatively. Subjects were grouped according to preoperative SF-12 MCS: <41 vs. ≥41. Demographic/perioperative variables, PROMs, and MCID were compared using inferential statistics. Multiple regression was used to account for differences in spinal pathology. Results The SF-12 MCS <41 and SF-12 MCS ≥41 groups included 48 and 45 patients, respectively. Significant differences in ΔPROMs were observed at SF-12 MCS at all timepoints, except at 6 months (p≤0.041, all). The SF-12 MCS <41 group had worse preoperative to 6-months SF-12 MCS, 12-weeks/6-months VAS back, 12-week VAS leg, and preoperative to 6-months ODI (p≤0.029, all). The SF-12 MCS <41 group had greater MCID achievement for overall ODI and 6-weeks/1-year/overall SF-12 MCS (p≤0.043, all); the SF-12 MCS ≥41 group had greater attainment for 6-month VAS back (p=0.004). Conclusions Poorer mental functioning adversely affected the baseline and intermediate postoperative quality-of-life outcomes pertaining to mental health, back pain, and disability among WC recipients undergoing lumbar fusion. However, outcomes did not differ 1–2 years after surgery. While MCID achievement for pain and physical function was largely ...

Abstract	Background: Given the variety in mitral valve (MV) pathology and associated surgical techniques, extended reality (XR) holds great potential to assist MV surgeons. This review aims to systematically evaluate the currently available evidence investigating the use of XR and associated technologies in MV surgery. Methods: A systematic database search was conducted of original articles and case reports that explored the use of XR and MV surgery in EMBASE, MEDLINE, Cochrane database and Google Scholar, from inception to February 2022. Results: Our search yielded 171 articles, of which 15 studies were included in this review, featuring 328 patients. Two main areas of application were identified: (i) pre-operative planning and (ii) predicting post-operative outcomes. The articles reporting outcomes relating to pre-operative planning were further categorised as exploring themes relevant to (i) mitral annular assessment; (ii) training; (iii) evaluation of surgical technique; (iv) surgical approach or plan and (v) selecting ring size or type. Preoperatively, XR has been shown to evaluate mitral annular pathology more accurately than echocardiography, informing the surgeon about the optimal surgical technique, approach and plan for a particular patient's MV pathology. Furthermore, XR could simulate and aid ring size/type selection for MV annuloplasty, creating a personalized surgical plan. Additionally, XR could estimate the postoperative MV biomechanical and physiological characteristics, predicting and pre-empting post-operative complications. Conclusion: XR demonstrated promising applications for assisting MV surgery, enhancing outcomes and patient-centred care, nevertheless, there remain the need for randomized studies to ascertain its feasibility, safety, and validity in clinical practice.

Abstract	Distribution and ecological risks of Phthalic acid esters (PAEs) are poorly studied in estuarine environments in India. An attempt is made to chart the sources and assess the ecological risk of six PAE congeners (∑₆PAEs), present in dissolved and particulate forms in a tropical ecosystem (Cochin Estuary, India). Terrestrial input, as attested by a clear seasonality with substantial enrichment during monsoon (2–28 μg/L and 31–1203 μg/g; dissolved and particulate PAEs respectively) and post-monsoon (1–7 μg/L and 7–321 μg/g; dissolved and particulate PAEs respectively), was identified as the primary source. DnBP (di-n-butyl phthalate) and DEHP (diethylhexyl phthalate) were found to be the dominant species except for dissolved PAEs at pre-monsoon season. Statistical analysis identified two major clusters, in the ∑₆PAEs, composed of medium to high molecular weight PAEs (derived from plastic products) and low molecular weight PAEs (derived from cosmetic products). Calculated Risk Quotient (RQ) indicated values indicated moderate to high ecological risk for DnBP and DEHP congeners is a grim pointer to their detrimental effects on human health through consumption of contaminated organisms. Although substantial enrichment of suspended matter gets flushed out of the estuary during monsoon, there is a net PAE accumulation in the estuary during post-monsoon following an increased sedimentary restitution. Data of PAEs generated herein raises a challenge for immediate enactment of statutory legislation to curb and regulate hazardous contamination of estuaries by phthalic acid esters.

Abstract	Objective: Redo mitral valve surgery has traditionally been performed via a median sternotomy. It is often challenging and is associated with increased perioperative mortality. Advances in cardiac surgical techniques over the last two decades have led to an increase in the use of a minimally invasive approach via a right anterolateral mini-thoracotomy as opposed to a repeat median sternotomy. However, despite these advances, there is no general consensus on the best form of entry, and as of yet, there are no randomized controlled trials. We performed a meta-analysis of observational studies to aid in determining the best approach for redo mitral valve surgery. Method: The MEDLINE and EMBASE databases were conducted up until 1 June 2020. Data regarding mortality, stroke, reoperation for bleeding and length of hospital stay, wound infection and cardiopulmonary bypass time were extracted and submitted to a meta-analysis using random effects modelling and the I Results: There were a total of 1070 patients. Of these 364 had non-sternotomy approach compared with 707 patients who had median sternotomy. Further subgroup analysis revealed that 327 of the 364 patients had a mini-thoracotomy approach while the remaining 37 patients had a full thoracotomy approach. In-hospital mortality and length of stay were less in non-sternotomy group compared to median sternotomy group. There were no differences in stroke, CPB time and wound infections between the two groups. Conclusion: Redo mitral valve surgery can be performed safely with satisfactory outcomes via a mini-thoracotomy approach. This meta-analysis shows comparable results with reduced in-hospital mortality and hospital length of stay with a mini-thoracotomy approach.

Abstract	Direct fluorination is one of the most important and effective method to modify the polymer surface. It isa simple and fast method that allows the simultaneous treatment of outer and inner surfaces of complex shapedpolymeric materials. Poly-p-phenylene terephthalamide fibers which are a very important class of material wassurface modified by direct fluorinaton. An extensive characterization of both the virgin and the fluorinated materialswere performed by various techniques (XRD, FT-IR, Surface energy and DSC, TGA). From these data, possibleeffects of fluorination are discussed. Defence Science Journal, Vol. 64, No. 3, May 2014, pp. 230-235, DOI: http://dx.doi.org/10.14429/dsj.64.7321

Abstract	A best evidence topic was constructed according to a structured protocol. The question addressed was whether (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) aids the diagnosis of prosthetic valve endocarditis (PVE)? A total of 107 publications were found using the reported search, of which 6 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. The reported outcome of all studies was a final diagnosis of confirmed endocarditis on follow-up. All the six studies were non-randomized, single-centre, observational studies and thus represented level 3 evidence. The diagnostic capability of PET/CT for PVE was compared with that of the modified Duke Criteria and echocardiography, and reported in terms of sensitivity, specificity and positive and negative predictive values. All studies demonstrated an increased sensitivity for the diagnosis of PVE when PET/CT was combined with the modified Duke Criteria on admission. A higher SUVmax on PET was found to be significantly associated with a confirmed diagnosis of endocarditis and an additional diagnostic benefit of PET/CT angiography over conventional PET/non-enhanced CT is reported due to improved anatomical resolution. However, PET/CT was found to be unreliable in the early postoperative period due to its inability to distinguish between infection and residual postoperative inflammatory changes. PET/CT was also found to be poor at diagnosing cases of native valve endocarditis. We conclude that PET/CT aids in the diagnosis of PVE when combined with the modified Duke Criteria on admission by increasing the diagnostic sensitivity. The diagnostic ability of PET/CT can be potentiated by the use of PET/CTA; however, its use may be unreliable in the early postoperative period or in native valve endocarditis.
