Abstract
5053 Background: Previous studies showed that men with HIV-associated germ cell cancer (HIV-GCC) have a similar cancer-free outcome compared with their HIV-negative counterparts. However, the overall survival (OS) was inferior and little data is available on treatment and outcome of HIV-GCC in the era of combined antiretroviral therapy (cART). Methods: Men living with HIV aged ≥ 18 years (yrs) with a diagnosis of histologically proven GCC made from 01/1996 to 07/2018 were included. Primary outcomes were OS and progression-free survival (PFS). Secondary outcomes included characteristics of GCC and HIV-infection, treatment and causes of death. Results: Data of 89 men from 23 institutions and 6 countries with a total of 92 HIV-GCC (2 synchronous and 1 metachronous bilateral GCC) were analysed, among them 64 (70%) seminomas and 28 (30%) nonseminomas. 10/89 (11%) cases were primary extragonadal GCC. Median age was 36 yrs (range, 22-52) and median time from HIV to GCC diagnosis was 5 yrs (range, 0-29). Median CD4 count at GCC diagnosis was 420 cells/µl (range, 3-1503) and 83% of pts were on cART. Stage I disease was found in 44/80 (55%) gonadal GCC (metachronous bilateral case included). Of 46 cases with stage II/III/extragonadal GCC 78%, 17% and 4% were assigned to the IGCCCG good, intermediate and poor prognosis group, respectively. Of the 44 stage I cases, 22 (50%) were followed by active surveillance, and 11 (25%) received adjuvant chemotherapy (CT) or radiotherapy. Relapses occurred in 14 pts (6 from stage I, 8 in pts primary disseminated GCC) and CT was applied to 13/14 pts, of which 3 received high-dose CT. Overall, 12/89 (13%) pts have died. Causes of death were refractory GCC (n = 5), an AIDS-defining illness (n = 3) and other (n = 4). After a median follow-up of 6.5 yrs (range, 0.3-20.9), the 5- and 10-year PFS rate was 81% and 73%, and the 5- and 10-year OS rate was 91% and 85%, respectively. There were no significant differences between the good and intermediate prognosis group or between pts with CD4 counts < 200/µl or ≥ 200/µl. Conclusions: The 5- and 10-year PFS and OS rates of men with HIV-GCC are similar to those reported for HIV-negative GCC. Pts with HIV-GCC should remain on cART and be managed in an identical fashion to HIV-negative pts.

Abstract
BACKGROUND To evaluate clinical outcomes after either immediate or deferred initiation of antiretroviral therapy in HIV-1-infected patients, presenting late with pneumocystis pneumonia (PCP) or toxoplasma encephalitis (TE). METHODS Phase IV, multicenter, prospective, randomized open-label clinical trial. Patients were randomized into an immediate therapy arm (starting antiretroviral therapy (ART) within 7 days after initiation of OI treatment) versus a deferred arm (starting ART after completing the OI-therapy). All patients were followed for 24 weeks. The rates of clinical progression (death, new or relapsing opportunistic infections (OI) and other grade 4 clinical endpoints) were compared, using a combined primary endpoint. Secondary endpoints were hospitalization rates after completion of OI treatment, incidence of immune reconstitution inflammatory syndrome (IRIS), virologic and immunological outcome, adherence to proteinase-inhibitor based antiretroviral therapy (ART) protocol and quality of life. RESULTS 61 patients (11 patients suffering TE, 50 with PCP) were enrolled. No differences between the two therapy groups in all examined primary and secondary endpoints could be identified: immunological and virologic outcome was similar in both groups, there was no significant difference in the incidence of IRIS (11 and 10 cases), furthermore 9 events (combined endpoint of death, new/relapsing OI and grade 4 events) occurred in each group. CONCLUSIONS In summary, this study supports the notion that immediate initiation of ART with a ritonavir-boosted proteinase-inhibitor and two nucleoside reverse transcriptase inhibitors is safe and has no negative effects on incidence of disease progression or IRIS, nor on immunological and virologic outcomes or on quality of life.

Abstract
We demonstrate electrical mapping of tetragonal domains and electric field-induced twin walls in SrTiO_{3} as a function of temperature and gate bias utilizing the conducting LaAlO_{3}/SrTiO_{3} interface and low-temperature scanning electron microscopy. Conducting twin walls appear below 105 K, and new twin patterns are observed after thermal cycling through the transition or on electric field gating. The nature of the twin walls is confirmed by calculating their intersection angles for different substrate orientations. Numerous walls formed when a large side- or back-gate voltage is applied are identified as field-induced ferroelectric twin walls in the paraelectric tetragonal matrix. The walls persist after switching off the electric field and on thermal cycling below 105 K. These observations point to a new type of ferroelectric functionality in SrTiO_{3}, which could be exploited together with magnetism and superconductivity in a multifunctional context.

Abstract
We investigate the structural and electronic properties of nitrogen-doped epitaxial monolayer graphene and quasifreestanding monolayer graphene on 6H-SiC(0001) by the normal incidence x-ray standing wave technique and by angle-resolved photoelectron spectroscopy supported by density functional theory simulations. With the location of various nitrogen species uniquely identified, we observe that for the same doping procedure, the graphene support, consisting of substrate and interface, strongly influences the structural as well as the electronic properties of the resulting doped graphene layer. Compared to epitaxial graphene, quasifreestanding graphene is found to contain fewer nitrogen dopants. However, this lack of dopants is compensated by the proximity of nitrogen atoms at the interface that yield a similar number of charge carriers in graphene.

Abstract
GaNAsSb/GaAs p-i-n photo notdetectors with an intrinsic GaNAsSb photoabsorption layer grown at 350 degrees C, 400 degrees C, 440 degrees C and 480 degrees C, have been prepared using radio-frequency nitrogen plasma-assisted molecular beam epitaxy in conjunction with a valved antimony cracker source. The i-GaNAsSb photoabsorption layer contains 3.3% of nitrogen and 8% of antimony, resulting in DC photo-response up to wavelengths of 1350 nm. The device with i-GaNAsSb layer grown at 350 degrees C exhibits extremely high photoresponsivity of 12A/W at 1.3 microm. These photodetectors show characteristics which strongly suggest the presence of carrier avalanche process at reverse bias less than 5V.

Abstract
Platypnea-orthodeoxia is a rare syndrome that is often associated with interatrial shunting through a patent foramen ovale (PFO) or atrial septal defect. We describe the case of a 69-year-old woman with progressive dyspnea and hypoxia when standing, which was relieved by assuming the recumbent position. After detection of a PFO by transesophageal echocardiography the diagnosis was confirmed by transthoracic echocardiography using saline contrast injection while lying supine and standing upright. This maneuver demonstrated a large right-to-left shunt through a patent foramen ovale while the patient was in a upright position and no significant shunt while being in a recumbent position. The patient showed a rapid improvement after closure of the PFO. This case demonstrates that platypnea-orthodeoxia caused by a patent foramen ovale can be easily demonstrated by the technique of contrast transthoracic echocardiography and a simple positioning maneuver.

Abstract
Thromboembolic and haemorrhagic complications are not rarely seen in the course of malignant diseases. The underlying coagulation disorders were investigated by means of coagulation analysis in 61 patients with solid tumors and 60 control persons as well as 51 patients with leukemia and 50 control persons. As a cause for the thrombotic diathesis in patients with solid tumors and leukemias can be demonstrated a hypercoagulability (shortened PTT and raised factor VIII activity). In addition we found a raised level of fibrinogen, a hypofibrinolysis (prolonged euglobulin lysis time) and in increased platelet aggregation in patients with solid tumors. Predominantly bleeding complications in leukemias are caused by thrombopenia. Another reason, however, may be an activated fibrinolysis or a clot instability because of the reduction of factor XIII. Pathogenetic mechanisms, underlying the tumor induced coagulation disorders, as for example the release of tumor cell thromboplastins from malignant cells are discussed.
