Abstract
OBJECTIVES Testicular germ cell tumours (TGCTs) are the most commonly diagnosed malignancy among active duty US military servicemen. Occupational risk factors may play a role in TGCT aetiology, although the evidence is inconclusive. The objective of our study was to investigate associations between military occupations and TGCT risk among US Air Force (USAF) servicemen. METHODS This nested case-control study among active duty USAF servicemen obtained information on military occupations for 530 histologically confirmed TGCT cases diagnosed during 1990-2018 and 530 individually matched controls. We determined military occupations using Air Force Specialty Codes ascertained at two time points: at case diagnosis and at a time point on average 6 years earlier. We computed adjusted ORs and 95% CIs from conditional logistic regression models to evaluate associations between occupations and TGCT risk. RESULTS The mean age at TGCT diagnosis was 30 years. Increased TGCT risk was observed for pilots (OR=2.84, 95% CI: 1.20-6.74) and servicemen with aircraft maintenance jobs (OR=1.85, 95% CI: 1.03-3.31) who held those jobs at both time points. Fighter pilots (n=18) and servicemen with firefighting jobs (n=18) at the time of case diagnosis had suggestively elevated TGCT odds (OR=2.73, 95% CI: 0.96-7.72 and OR=1.94, 95% CI: 0.72-5.20, respectively). CONCLUSIONS In this matched, nested case-control study of young active duty USAF servicemen, we found that pilots and men with aircraft maintenance jobs had elevated TGCT risk. Further research is needed to elucidate specific occupational exposures underlying these associations.

Abstract
Abstract
For patients with coronary artery disease, hypertension (HTN) is a major risk factor. How could uncontrolled HTN start atherosclerosis? In our prior research, laminar flow in coronary arteries prevented the formation of plaques while turbulent flow injured the intima and triggered atherosclerosis. In this present study our question was: Which blood pressure (BP) level is optimal in not producing turbulence and so not injuring the intima?
Methods
At first, a systolic BP<120mmHg and diastolic BP<75mmHg) were arbitrarily set as controlled (group A) while a BP of >160/105mmHg as uncontrolled (group B). All patients underwent a dynamic coronary angiogram recorded at 15 images/second or 0.06 seconds per image. The first image was of the index artery completely filled with contrast. In subsequent images the blood in white color moved in over a background of black contrast (Figure 1A). In 1B, 0.06 seconds later, the blood arrived at the mid segment (white arrow). In 1C, the flood moved forward, however there was darker contrast hanging at the mid segment, marking the location of collision from the retrograde against the antegrade flow (white arrow). The reason was that in uncontrolled BP the contraction of the left ventricle was stronger so in systole, the coronary blood could reverse its course, run on a retrograde direction, collide against the antegrade flow and create turbulence (1C).
At the end, before deploying a vascular closure device, an iliac angiogram was performed. In Figure 2, on a black background of contrast, the blood in white color moved forward with a pointed tip of laminar flow. 0.06 seconds later, the laminar tip was stopped abruptly with all the layers recoiling on each other like a falling stack of dominoes. In the next image. a large swirl of disorganized mixing of blood and contrast suggested the presence of turbulence caused by the collision.
The data to be collected were (1) the duration of the antegrade and retrograde flow, (2) duration of the collision (turbulence at the collision site)
Results
In the group A (BP <120/75 mmHg), 90% of 20 patients had no retrograde flow nor collision in the iliac and short collision in coronary arteries (<0.12 secs). In 30 patients of group B (BP >160/105 mmHg), the duration of retrograde flow and collision in the iliac artery were prolonged at >0.24 msecs. In the coronary arteries, the duration was prolonged at 0.18 msecs (all p<0.05 compared with group A). These locations of turbulence correlated with the location of plaques in our prior studies.
Conclusion
In patients with uncontrolled HTN, the retrograde flow was prolonged, and the turbulence was intense. In contrary, for patients with controlled BP, there was no retrograde flow and weaker collision in coronary arteries. The results suggest that a BP of <120/75 mmHg may not trigger the atherosclerotic process. New clinical trials with larger number of patients should be performed in search for the lowest ideal blood pressure.

Abstract
BACKGROUND/PURPOSE The successful recruitment and retention of participants is integral to the translation of research findings. Recruitment begins once you have defined your focus population and identified where and how to reach them (i.e., targeting). Formative evaluation can provide valuable information on recruitment, given the dynamics of different communities and the potential for certain strategies to work better than others with high-risk groups. The preliminary work of engaging the population of interest is essential to successfully attracting and retaining the involvement of populations of interest. The purpose of this paper is to present methods used to engage college students in a multi-level intervention aimed at preventing substance abuse, HIV and STIs. THEORETICAL FRAMEWORK Andreasen's six principles of social marketing were used to develop intervention activities and engage students in these activities. METHODS A multi-method approach was employed using both survey and focus groups for preliminary feedback, post-event surveys and annual evaluations. RESULTS Pamphlets are not enough to attract potential participants because advertisements need to be engaging and employ social networking sites. Students also enjoy playing both on-line and in person games and are quite competitive. Testing for HIV tripled in the first year. CONCLUSIONS & IMPLICATIONS Students became more aware with each subsequent event participation increased over time. Although word of mouth is still very effective in getting students to events, the use of social networking sites greatly improved student participation.

Abstract
Abstract
Roughly a third of ovarian cancer patients are intrinsically resistant to platinum-based treatment. However, predictive and therapeutic strategies are lacking to treat these patients due to a poor understanding of the underlying molecular mechanisms. We previously identified and validated a “reactive stroma” gene signature that is associated with primary chemoresistance in epithelial ovarian cancers (EOCs). In addition this signature was further validated in an independent dataset and high expression level of the signature genes predicts shorter progression free survival following front line chemotherapy. One of the key components of this gene signature is periostin (POSTN), an extracellular matrix protein known for its role in a variety of tissue remodeling conditions as well as overexpression in many types of cancers. Interestingly, POSTN is also involved in aspects of allergic inflammation and is used as a circulating biomarker for TH2-driven asthma. To investigate whether circulating POSTN could be used to predict chemoresistance in EOC, we developed an ELISA assay for detecting circulating POSTN in serum and plasma. Serum POSTN levels were measured in panels of serum samples from 143 EOC patients, 102 normal healthy subjects (NHS) and from 126 patients with other cancers. The serum POSTN ELISA was sensitive down to 1.88ng/mL and POSTN was detected in the serum of all patients and NHS. Although the range of POSTN expression in the EOC patients was highly overlapping with that of normal healthy subjects, a positive correlation was observed with the stage of disease. Retrospective and prospective studies are underway to determine whether baseline serum-POSTN levels can predict chemoresistance in EOC patients. Our study may lead to the development of a novel diagnostic strategy for predicting response to chemotherapy in ovarian cancer.

Abstract
Among the three main factors of motor impairment that emerge in chronological order following a lesion to central motor pathways, the last two antagonize movement: 1) stretch-sensitive paresis, a reduction of agonist motor unit recruitment upon voluntary command, worsened by antagonist stretch; 2) soft tissue contracture, and 3) muscle overactivity. Types of muscle overactivity include 1) spasticity, an increase in the velocity-dependent response to muscle stretch, measured at rest; 2) spastic dystonia, i.e., chronic tonic muscle activity at rest, sensitive to stretch of the dystonic muscle and 3) spastic co-contraction, an inappropriate degree of antagonistic contraction during voluntary agonist command, sensitive to stretch of the co-contracting muscle. A five-step clinical assessment may closely parallel this phenomenology, in which the first four steps aim at quantifying the antagonistic potential of each muscle group. Step-1 measures passive range of motion, i.e., the angle of arrest upon slow stretch of the muscle group assessed (minimizing spastic dystonia), which provides insight on soft tissue length and extensibility. Step-2 measures the angle of catch or clonus upon fast passive stretch of the muscle group assessed, which provides insight on stretch reflex excitability. Step-3 measures the range of active motion against the muscle group assessed, a net result of agonist recruitment minus the combined resistance from passive soft tissue stiffness and spastic co-contraction in the muscle group assessed. Step-4 measures the maximal frequency of rapid alternating movements along the maximal active range of motion, evaluating Step-3 performance repeatability. Step-5 evaluates active function, using for example a walking test (10 m or 2 min) for lower limb and the Modified Frenchay Scale for upper limb assessment, and perceived function through patient global subjective assessment.

Abstract #1047
Background: In breast cancer, previous studies have shown that somatic TP53 mutations cause a more aggressive disease with poor clinical outcome and may impact treatment response. Although TP53 mutation is considered to be an early event in breast cancer, the timing of TP53 mutations is not known, and there are controversies regarding the cellular origin and linear model of breast cancer. The purpose of this study was to investigate whether TP53 mutations are early events in breast cancer progression.
 Methods: From a population-based cohort of women diagnosed between 1986 and 2004 either with a pure ductal carcinoma in situ (DCIS), a pure invasive cancer (<15mm) or a mixed lesion (i.e. invasive cancer with a DCIS component), we included 118 women with stored frozen tissue. Mixed lesions were microdissected using LCM (laser capture microdissection) on a PALM slide to separate in situ and invasive tumor cells. DNA was isolated using phenol-chloroform extraction. The entire coding sequence of TP53 was analyzed for mutations by direct sequencing on a 3730 DNA analyzer.
 Results: Of 118 tumor samples, 19 were detected with a TP53 mutation; five 5 of 32 (15.6%) pure DCIS, 4 of 38 (10.5%) pure invasive cancers and 10 of 48 (20.8%) mixed lesions. In the mixed lesions, both the invasive and the DCIS component showed the same mutation in all 5 cases where we successfully could microdissect the two components separately. Pure DCIS demonstrated missense mutations (4/5, 80%) more frequently than pure invasive cancers (2/4, 50%) and mixed lesions (4/10, 40%), although this difference was not statistically significant (p=0.3). Also, the frequency of missense mutations in the DNA binding domain was not statistically different between the three groups.
 Conclusion: TP53 mutation is likely an early event in breast cancer, occurring previous to or in the in situ stage. Presence of the same mutation in both DCIS and invasive component from the same tumor indicates same cellular origin. The role of mutant TP53 in the progression into invasive cancer is less clear and may vary between subtypes of breast cancer.

Abstract
The parenteral drug application is a routinely used method in all medical disciplines. Intramuscular, intraarticular, intravenous injections and infusions can cause local complications such as abscesses, articular infections or paravasates. These local complications can lead to bacteraemia, sepsis and may lead to multiple organ failure associated with high morbidity and mortality. Although these complications are rare, they are sometimes disastrous and result in life threatening clinical conditions. During a retrospective analysis (review period 1998-2002) 24 patients were admitted and hospitalized in our department. Within this report we demonstrate 7 patients with fatal complications after injections. In the majority of cases minor patients' complaints were proceeding before major complications were present. A long and expensive treatment period with multiple surgical interventions ends up in functional disabilities and unsatisfactory aesthetic results. Instead of delayed surgical treatment immediate radical surgical care is crucial to prevent disastrous complications. In case of the inability of sufficient debridement, amputations are sometimes indicated in the sense of "life before limb". Besides the consequences for the patient these disastrous complications have a high socioeconomic impact and result in reduced reimbursement for the hospital stay.

Abstract
In order to assess clock-time estimation (CTE), we asked "what time is it in your opinion?" to 48 recent stroke in-patients, 21 with right (RH), 27 with left hemispheric (LH) lesions, and to 20 control in-patients without brain lesions (C). Errors were measured in terms of the number of minutes by which the estimated clock-time was later (advance errors) or earlier (delay errors) than the real clock-time. CTE was considered pathological when exceeding the mean advance or delay errors observed in control patients plus 2.5 standard deviations. The estimation of the duration of a short psychological interview was also assessed. CTE, and not duration estimation, was disturbed in patients. RH patients made significantly more pathological advance errors than LH patients (43% vs. 12%). This study points out the RH dominance for CTE in stroke patients.

Abstract
We report a case of pontine infarct that occurred after facial trauma with a fracture of the skull base. Reports of trauma-induced pontine infarcts have generally involved cervical trauma. This is the first report to our knowledge after facial trauma with skull base fracture. We suggest that intracranial vertebro-basilar dissection could be a possible mechanism.

Abstract
483 Norwegian breast cancer patients were screened for six different ataxia telangiectasia mutated (ATM) mutations previously found to account for 83% of the disease alleles in Norwegian ataxia telangiectasia (AT) patients. Only one carrier was found. These results provide no evidence in favour of an excess risk of breast cancer associated with heterozygosity for classical AT mutations, but remain consistent with a maximum 2.4-fold increased risk.

Abstract
The A-G polymorphism at codon 104 in the glutathione S-transferase P1 (GSTP1) gene was examined in 138 male lung cancer patients and 297 healthy controls. The patients had significantly higher frequency of the GG genotype (15.9%) and a lower frequency of AA (38.4%) than the controls (9.1% and 51.5%, respectively). The level of hydrophobic DNA-adducts were determined in lung tissue from 70 current smokers. Patients with the GG genotype had a significantly higher adduct level than patients with AA (15.5 +/- 10.2 vs 7.9 +/- 5.1 per 10(8) nucleotides, P = 0.006). We also analyzed the deletion polymorphism in the GSTM1 gene in 135 male patients and 342 controls. The patients were stratified according to histology, smoking dose, age, adduct level and mutational types found in the tumors (Ki-ras and p53 genes). The results consistently indicated that the GSTM1 null genotype was associated with a slightly increased lung cancer risk. When the combined GST M1 and P1 genotypes were examined, patients with the combination null and AG or GG had significantly higher adduct levels than all other genotype combinations (P = 0.011). The distribution of combined genotypes was also significantly different in cases and controls, mainly due to increased frequency of the combination GSTM1 null and GSTP1 AG or GG among patients.

Abstract
In order to explore the possibility of serratus anterior muscle (SAM) flap transposition in head-neck and thoracic surgery, we performed an anatomical study including 40 dissections of the muscle's vascular pedicle, the subscapular-thoracodorsal axis, which is a branch of the axillary artery (A. subscapularis A. thoracodorsalis). The SAM is characterized by: its location: extending from the anterior and lateral aspect of the thorax to the medial border of the scapula; its easy surgical access; its constant and reliable vascularization by the thoracodorsal artery, a branch of the subscapular artery; its long arc of rotation allowing the utilization of the SAM flap in head and neck and mediastinal surgery without microvascular anastomoses; its versatility in comparison with other perithoracic muscles. These considerations prompted us to use the SAM in head and neck reconstructive surgery, chest wall surgery, chest wall reconstruction following resection for tumor; breast reconstruction; intrathoracic and mediastinal surgery, reinforcement of high-risk tracheobronchial sutures or anastomoses; management of bronchopleural fistulas and empyema spaces; repair of tracheo esophageal fistulas and tracheal or esophageal defects.
