Abstract
We examine the phenomenology of the production, at the 13 TeV Large Hadron Collider (LHC), of a heavy resonance X, which decays via other new on-shell particles n into multi-(i.e. three or more) photon final states. In the limit that n has a much smaller mass than X, the multi-photon final state may dominantly appear as a two-photon final state because the γ s from the n decay are highly collinear and remain unresolved. We discuss how to discriminate this scenario from X → γ γ : rather than discarding non-isolated photons, it is better to relax the isolation criteria and instead form photon jets substructure variables. The spins of X and n leave their imprint upon the distribution of pseudo-rapidity gap Δ η between the apparent two-photon states. Depending on the total integrated luminosity, this can be used in many cases to claim discrimination between the possible spin choices of X and n, although the case where X and n are both scalar particles cannot be discriminated from the direct X → γ γ decay in this manner. Information on the mass of n can be gained by considering the mass of each photon jet.

Abstract
Identifying noninvasive biomarkers of kidney disease is valuable for diagnostic and therapeutic purposes. Hypoxia inducible factor 1 (HIF-1) expression is known to be elevated in the kidneys in several renal disease pathologies. We hypothesized that the urinary HIF-1a mRNA level may be a suitable biomarker for expression of this protein in chronic kidney disease (CKD). We compared HIF-1a mRNA levels from urine pellets of CKD and healthy subjects. To ensure that urinary HIF-1a mRNA is of kidney origin, we examined colocalization of HIF-1a mRNA with two kidney specific markers in urine cells. We found that HIF-1a mRNA is readily quantifiable in urine pellets and its expression was significantly higher in CKD patients compared with healthy adults. We also showed that the urinary HIF-1a mRNA comes primarily from cells of renal origin. Our data suggest that urinary HIF-1a mRNA is a potential biomarker in CKD and can be noninvasively assessed in patients.

Abstract
BACKGROUND The platelet GP IIb/IIIa inhibitor eptifibatide improves outcomes in patients with acute coronary syndromes. Patients requiring emergent coronary artery bypass grafting, however, may be at increased risk for bleeding if exposed to eptifibatide. Data from the PURSUIT trial were reviewed to assess this risk in patients undergoing coronary surgery immediately after exposure to eptifibatide. METHODS In PURSUIT, 10,948 patients who presented with non-ST segment elevation acute coronary syndromes were prospectively randomized to receive eptifibatide (180 microg/kg bolus plus 2 microg/kg/min infusion) or placebo. A total of 78 patients underwent immediate coronary artery bypass surgery within 2 hours of cessation of study drug (placebo, n = 46; eptifibatide, n = 32). Clinical outcome, bleeding, and transfusion requirements within this subset were examined. RESULTS Major bleeding was not different between groups, occurring in 64% of patients receiving placebo and 63% of patients receiving eptifibatide. The incidence of blood transfusion was similar as well (57% vs 59%). Postoperative thrombocytopenia occurred less often after eptifibatide exposure. Perioperative myocardial infarction was significantly reduced in patients who received eptifibatide (46% vs 22%, p < 0.05). There was no difference in perioperative stroke (2.2% vs 6.3%) or mortality (6.3% vs 6.5%). CONCLUSIONS Patients may safely undergo coronary artery bypass surgery within 2 hours of discontinuation of eptifibatide. Eptifibatide infusion in the immediate preoperative period had no adverse clinical effects, but did significantly decrease the incidence of perioperative myocardial infarction. Additionally, platelet counts after surgery were higher in the group of patients who received eptifibatide, perhaps indicative of a platelet-sparing effect during cardiopulmonary bypass.

Abstract
Platelet-mediated thrombosis has a pivotal role in the pathophysiology of acute ischemic coronary syndromes (AICS) and the acute complications of percutaneous coronary interventions. Because cross-linking of the activated platelet receptor glycoprotein (GP) IIb-IIIa by plasma fibrinogen represents the final common pathway to coronary thrombus formation, several GP IIb-IIIa inhibitors have been developed as a potentially more effective antithrombotic therapy than agents currently used for this purpose, namely aspirin and heparin. However, use of GP IIb-IIIa inhibitors in patients with AICS and those scheduled for percutaneous coronary interventions may increase the risk of serious clinical and bleeding events among patients who require emergency or urgent bypass surgery. This review describes clinical experience with various GP IIb-IIIa inhibitors and suggests management strategies for patients undergoing emergency or urgent bypass surgery shortly after treatment with GP IIb-IIIa inhibitors.

Abstract
Over a one year period (June 1992-June 1993), 260 patients (208 females and 52 males) with mean age of 37 years (range 13-80), underwent laparoscopic cholecystectomy (LC) for symptomatic gallstones. Thirty patients were admitted as emergency (20 acute cholecystitis, 10 acute pancreatitis). The procedure was performed successfully in 232 cases (89%). In 28 patients (18 electives, 10 emergencies), the procedure was converted to open for a variety of reasons, difficult anatomy being the commonest. Our mean operative time was 99.9 minutes (range 30-290 minutes). There were 3 major complications (2 common bile duct injuries and one abdominal aortic injury) and 4 minor complications (2 wound infections, one prolonged ileus and one chest infection). There was one death due to sickle cell crisis on the fifth post-operative day. The mean hospital stay was 2.3 days and 6.5 days for LC and converted cases, respectively. Our results suggest that laparoscopic cholecystectomy can be offered and conducted safely and effectively in the great majority of patients presenting acutely or electively with cholelithiasis, and that the results we achieved during the first year of our experience with LC is comparable to those reported from Europe and North America.

Abstract
We have studied the long-term results of core decompression as the sole treatment for Ficat stages I, II and III ischaemic necrosis of 128 femoral heads in 90 patients. The 5-, 10- and 15-year survival rates for the three stages were respectively: stage I 100%, 96% and 90%; stage II 85%, 74% and 66%; and stage III 58%, 35% and 23%. At a mean follow-up of 11 years (4.5 to 19), 55 hips had failed (43%). No further surgery had been needed for 88% of stage-I, 72% of stage-II and 26% of stage-III hips; but despite the generally satisfactory clinical results, 56% of the hips had progressed radiographically by at least one Ficat stage. Complications of the core procedure included four fractures, all from postoperative falls, and one head perforation due to technical error. We conclude that core decompression delays the need for total hip replacement in young patients with ischaemic necrosis.

Abstract
The aim of this study was to determine the anatomical restraints to dislocation of the second metatarsophalangeal joint and to assess the biomechanical efficacy of a technique that is commonly used to stabilize this joint. Cadaveric feet were disarticulated at the ankle, with preservation of the long flexor tendons at the medial malleolus. The hindfoot was transfixed to an aluminum jig, and a contoured nylon block was secured to the dorsum of the second metatarsal. A Kirschner wire was passed transversely through the proximal phalanx and was attached to a wire loop through which a constant vertical displacement was applied with a universal testing machine. A preload of five newtons was applied, followed by a constant displacement of two millimeters per minute, and the load-displacement curves were measured. The volar plate and the collateral ligaments were divided in five feet each. In another ten feet, both of these structures were divided simultaneously. Each load cycle was repeated four times. The force required to dislocate the joint, in the position in which testing was performed, was reduced by a mean of 30 per cent when the volar plate was divided and by a mean of 46 per cent when the collateral ligaments were divided. Division of both of these structures created an unstable joint, which dislocated at an applied load of five to ten newtons. The metatarsophalangeal joint was then repaired with use of a flexor tendon transfer in all twenty feet. This repair technique restored the load-displacement curves to that of the normal toe.

Abstract
The growth status of anemic (n = 117, Hb 7-10 g/dl) and normal (n = 53, H > or = 11 g/dl) children 3-5 years of age living under similar environmental and socio-economic conditions was evaluated. The dietary intake was assessed on a random subsample of the anemic and normal children. The anemic children had a poorer growth status than normal children as indicated by their significantly (p < 0.001) lower body weight, height and weight for age and significantly (p < 0.001) larger number in Grades II and III malnutrition. Iron supplementation (40 mg elemental iron/day) for six months produced a significant (p < 0.001) increase in Hb levels of both groups (1.6 g/dl in the anemic and 0.8 g/dl in the non-anemic) compared to their respective controls who received sugar placebos. The growth performance of the anemic children supplemented with iron was superior to that of anemic placebo treated children as indicated by a better weight gain and a significantly higher weight for height (p < 0.05). Weight for age was a good differentiator of the anemic from normal while weight for height was a good indicator of the impact of iron supplements on growth.

The oral administration of mesalazine (5-aminosalicylic acid) resulted in the exacerbation of ulcerative colitis in two patients intolerant to sulphasalazine whose colitis had previously been quiescent. Although sulphasalazine intolerance is usually attributable to the sulphapyridine moiety, the possibility of salicylate sensitivity should be considered in colitic patients who fail to respond appropriately to sulphasalazine or who experience abdominal pain or diarrhoea while taking the drug.
