A reduction in teen pregnancy and subsequent reduction in teen births correlates to myriad improvements in personal (e.g., high school completion, experience of abuse and neglect, etc); social (e.g., number of children in single parent families, life-long poverty, incarceration rates, etc); and economic (e.g., Medicaid costs, decreased tax revenue, etc) outcomes. In 2005, over 73,000 teen girls in Texas age 15-19 became pregnant, a number significantly higher than any other state. Given the severity of the issue the formation of a statewide organization in Texas devoted to addressing the prevention of teen pregnancy is long overdue. The challenge of reducing teen pregnancy is daunting yet there is momentum and a cadre of committed individuals who have formally put together an organization to provide guidance, oversight and a statewide voice of leadership - all things needed to be successful reducing teen pregnancy in Texas. This commentary provides reactions to proposed strategies and to-date lessons learned.

A micro-electrospray interface was developed specifically for the neurobiological applications described in this dissertation. Incorporation of a unique nano-flow liquid chromatography micro-electrospray "needle" into the micro-electrospray interface (micro-ES/MS) increased the sensitivity of the mass spectrometric assay by $\sim$1000 fold and thus permitted the first analysis of specific neuroactive compounds in brain extracellular fluid collected by in vivo microdialysis (Md).^ Initial in vivo data presented deals with the pharmacodynamics of a novel GABA$\sb{\rm B}$ antagonist and the availability of the compound in its parent (unmetabolized) form to the brain of the anesthetized rat. Next, the first structurally specific endogenous release of (Met) $\sp5$-enkephalin was demonstrated in unanesthetized freely-moving animals (release of $\sim$6.5 fmole of (Met) $\sp5$-enkephalin into the dialysate by direct neuronal depolarization). The Md/micro-ES/MS system was used to test the acute effects of drugs of abuse on the endogenous release of (Met) $\sp5$-enkephalin from the globus pallidus/ventral pallidum brain region in rats. Four drugs known to be abused by man (morphine, cocaine, methamphetamine and diazepam) were tested. Morphine and cocaine both elicited a two-fold or more increase in the release of (Met) $\sp5$-enkephalin over vehicle controls. Diazepam elicited a small decrease in (Met) $\sp5$-enkephalin levels and methamphetamine showed no significant effect on (Met) $\sp5$-enkephalin. These results imply that (Met) $\sp5$-enkephalin may be involved in the reward pathway of certain drugs of abuse. ^

Purpose/objectives. A grounded theory design was used to identify, describe, and generate a theoretical analysis of the pain experience of elderly hospice patients with cancer. ^ Sample. Eleven participants over the age of 65, receiving services from a for-profit hospice were interviewed in their homes. ^ Methods. Broad unstructured face to face audio-taped interviews were transcribed verbatim and analyzed using constant-comparative method of analysis. ^ Findings. Pain was described as a hierarchy of chronic, acute, and psychological pain with psychological pain as the worst. Suffering was the basic social problem of pain. Participants dealt with suffering by the basic social process of enduring. Enduring had two sub-processes, maintaining hope and adjusting. Trusting in a higher being and finding meaning were mechanisms of maintaining hope. Mechanisms of adjusting were dealing with uncertainty, accepting, and minimizing pain. ^ Implications for nursing practice. Nurses need to recognize and value the hard work of enduring to deal with suffering. Assisting elderly hospice patients with cancer to address the sub-processes of enduring and their mechanisms can foster enduring. ^

The treatment of peri-prosthetic joint infection (PJI) of the ankle is not standardised. It is not clear whether an algorithm developed for hip and knee PJI can be used in the management of PJI of the ankle. We evaluated the outcome, at two or more years post-operatively, in 34 patients with PJI of the ankle, identified from a cohort of 511 patients who had undergone total ankle replacement. Their median age was 62.1 years (53.3 to 68.2), and 20 patients were women. Infection was exogenous in 28 (82.4%) and haematogenous in six (17.6%); 19 (55.9%) were acute infections and 15 (44.1%) chronic. Staphylococci were the cause of 24 infections (70.6%). Surgery with retention of one or both components was undertaken in 21 patients (61.8%), both components were replaced in ten (29.4%), and arthrodesis was undertaken in three (8.8%). An infection-free outcome with satisfactory function of the ankle was obtained in 23 patients (67.6%). The best rate of cure followed the exchange of both components (9/10, 90%). In the 21 patients in whom one or both components were retained, four had a relapse of the same infecting organism and three had an infection with another organism. Hence the rate of cure was 66.7% (14 of 21). In these 21 patients, we compared the treatment given to an algorithm developed for the treatment of PJI of the knee and hip. In 17 (80.9%) patients, treatment was not according to the algorithm. Most (11 of 17) had only one criterion against retention of one or both components. In all, ten of 11 patients with severe soft-tissue compromise as a single criterion had a relapse-free survival. We propose that the treatment concept for PJI of the ankle requires adaptation of the grading of quality of the soft tissues. Cite this article: Bone Joint J 2014;96-B:772-7.

Multichannel EEG of an advanced meditator was recorded during four different, repeated meditations. Locations of intracerebral source gravity centers as well as Low Resolution Electromagnetic Tomography (LORETA) functional images of the EEG 'gamma' (35-44 Hz) frequency band activity differed significantly between meditations. Thus, during volitionally self-initiated, altered states of consciousness that were associated with different subjective meditation states, different brain neuronal populations were active. The brain areas predominantly involved during the self-induced meditation states aiming at visualization (right posterior) and verbalization (left central) agreed with known brain functional neuroanatomy. The brain areas involved in the self-induced, meditational dissolution and reconstitution of the experience of the self (right fronto-temporal) are discussed in the context of neural substrates implicated in normal self-representation and reality testing, as well as in depersonalization disorders and detachment from self after brain lesions.

OBJECTIVES Despite new treatment modalities, cyclophosphamide (CYC) remains a cornerstone in the treatment of organ or life-threatening vasculitides and connective tissue disorders. We aimed at analysing the short- and long-term side-effects of CYC treatment in patients with systemic autoimmune diseases. METHODS Chart review and phone interviews regarding side effects of CYC in patients with systemic autoimmune diseases treated between 1984 and 2011 in a single university centre. Adverse events were stratified according to the "Common Terminology Criteria for Adverse Events" version 4. RESULTS A total of 168 patients were included. Cumulative CYC dose was 7.45 g (range 0.5-205 g). Gastro-intestinal side effects were seen in 68 events, hair loss occurred in 38 events. A total of 58 infections were diagnosed in 44/168 patients (26.2%) with 9/44 suffering multiple infections. Severity grading of infections was low in 37/58 cases (63.8%). One CYC-related infection-induced death (0.6%) was registered. Amenorrhoea occurred in 7/92 females (7.6%) with 5/7 remaining irreversible. In females with reversible amenorrhoea, prophylaxis with nafarelin had been administered. Malignancy was registered in 19 patients after 4.7 years (median, range 0.25-22.25) presenting as 4 premalignancies and 18 malignancies, 3 patients suffered 2 premalignancies/malignancies each. Patients with malignancies were older with a higher cumulative CYC dose. Death was registered in 28 patients (16.6%) with 2/28 probably related to CYC. CONCLUSIONS Considering the organ or life-threatening conditions which indicate the use of CYC, severe drug-induced health problems were rare. Our data confirm the necessity to follow-up patients long-term for timely diagnosis of malignancies. CYC side-effects do not per se justify prescription of newer drugs or biologic agents in the treatment of autoimmune diseases.

A joint impact hypothesis on symptom experience is introduced that specifies the role of negative mood and self-focus, which have been considered independently in previous research. Accordingly, negative affect only promotes symptom experience when people simultaneously focus their attention on the self. One correlational study and 4 experiments supported this prediction: Only negative mood combined with self-focus facilitated the experience (see the self-reports in Studies 1, 2a, & 2b) and the accessibility (lexical decisions, Stroop task in Studies 3 & 4) of physical symptoms, whereas neither positive mood nor negative mood without self-focus did. Furthermore, the joint impact of negative mood and self-focused attention on momentary symptom experience remained significant after controlling for the influence of dispositional symptom reporting and neuroticism.

OBJECTIVES Megacystis (MC) is rare and often associated with other structural and chromosomal anomalies. In euploid cases with early oligohydramnios, prognosis is poor mainly due to pulmonary hypoplasia and renal damage. We report our experience of the past 20 years. METHODS A retrospective review of cases with prenatally diagnosed MC was performed. Complete prenatal as well as postnatal medical records from 1989 to 2009 were reviewed focusing on diagnostic precision, fetal interventions [vesicocentesis (VC), vesicoamniotic shunt (VAS)], short- and long-term outcome, and potential prognostic factors. RESULTS 68 cases were included. Follow-up was available in 54 cases (9 girls and 45 boys including 3 cases with aneuploidy). We found 39 isolated MC at sonography (5 girls and 34 boys). 24 fetuses with isolated MC underwent VC and VAS at 19.6 ± 6.3 and 20 ± 4.9 weeks of gestation, respectively. Survival rate was higher in male than in female fetuses (51 vs. 33%). Renal problems occurred in 4/14 prenatally treated fetuses and in 1/10 when cases with prune belly syndrome (PBS) were excluded from the analysis. CONCLUSIONS Our study shows that a careful selection of cases with MC excluding fetuses with PBS and early treatment has still the potential to improve outcome.

Space debris in geostationary orbits may be detected with optical telescopes when the objects are illuminated by the Sun. The advantage compared to Radar can be found in the illumination: radar illuminates the objects and thus the detection sensitivity depletest proportional to the fourth power of the d istance. The German Space Operation Center, GSOC, together with the Astronomical Institute of the University of Bern, AIUB, are setting up a telescope system called SMARTnet to demonstrate the capability of performing geostationary surveillance. Such a telescope system will consist of two telescopes on one mount: a smaller telescope with an aperture of 20cm will serve for fast survey while the larger one, a telescope with an aperture of 50cm, will be used for follow-up observations. The telescopes will be operated by GSOC from Oberpfaffenhofen by the internal monitoring and control system called SMARTnetMAC. The observation plan will be generated by MARTnetPlanning seven days in advance by applying an optimized planning scheduler, taking into account fault time like cloudy nights, priority of objects etc. From each picture taken, stars will be identified and everything not being a star is treated as a possible object. If the same object can be identified on multiple pictures within a short time span, the trace is called a tracklet. In the next step, several tracklets will be correlated to identify individual objects, ephemeris data for these objects are generated and catalogued . This will allow for services like collision avoidance to ensure safe operations for GSOC’s satellites. The complete data processing chain is handled by BACARDI, the backbone catalogue of relational debris information and is presented as a poster.

BACKGROUND In recent years, the scientific discussion has focused on new strategies to enable a torn anterior cruciate ligament (ACL) to heal into mechanically stable scar tissue. Dynamic intraligamentary stabilization (DIS) was first performed in a pilot study of 10 patients. The purpose of the current study was to evaluate whether DIS would lead to similarly sufficient stability and good clinical function in a larger case series. METHODS Acute ACL ruptures were treated by using an internal stabilizer, combined with anatomical repositioning of torn bundles and microfracturing to promote self-healing. Clinical assessment (Tegner, Lysholm, IKDC, and visual analogue scale [VAS] for patient satisfaction scores) and assessment of knee laxity was performed at 3, 6, 12, and 24 months. A one-sample design with a non-inferiority margin was chosen to compare the preoperative and postoperative IKDS and Lysholm scores. RESULTS 278 patients with a 6:4 male to female ratio were included. Average patient age was 31 years. Preoperative mean IKDC, Lysholm, and Tegner scores were 98.8, 99.3, and 5.1 points, respectively. The mean anteroposterior (AP) translation difference from the healthy contralateral knee was 4.7 mm preoperatively. After DIS treatment, the mean 12-month IKDC, Lysholm, and Tegner scores were 93.6, 96.2, and 4.9 points, respectively, and the mean AP translation difference was 2.3 mm. All these outcomes were significantly non-inferior to the preoperative or healthy contralateral values (p < 0.0001). Mean patient satisfaction was 8.8 (VAS 0-10). Eight ACL reruptures occurred and 3 patients reported insufficient subjective stability of the knee at the end of the study period. CONCLUSIONS Anatomical repositioning, along with DIS and microfracturing, leads to clinically stable healing of the torn ACL in the large majority of patients. Most patients exhibited almost normal knee function, reported excellent satisfaction, and were able to return to their previous levels of sporting activity. Moreover, this strategy resulted in stable healing of all sutured menisci, which could lower the rate of osteoarthritic changes in future. The present findings support the discussion of a new paradigm in ACL treatment based on preservation and self-healing of the torn ligament.

Viewing sports on television is a very different experience than viewing a game in-person. Sports commentators on television are seemingly able to pull up random statistics as soon as something unexpected happens during a game. Because these statistics are discussed on television, any sports fan who wants to watch a game in-person misses out on the opportunity to hear them during the game. This study identifies what statistics, both common and uncommon, are considered important or interesting by avid sports fans who watch a particular sport at least two times per week. In addition, it considers the rise of mobile technology and the effects that this change of trend will have on business opportunities and experiences. The purpose of the project is to find a way to mimic the television viewing experience for fans who are watching in-person through the use of mobile technology, and in particular through the use of iPhone applications.

We study how the democratization of the diffusion of research through the Internet could have helped non traditional fields of research. The specific case we approach is Heterodox Economics as its pre-prints are disseminated through NEP, the email alert service of RePEc. Comparing heterodox and mainstream papers, we find that heterodox ones are quite systematically more downloaded, and particularly so when considering downloads per subscriber. We conclude that the Internet definitely helps heterodox research, also because other researcher get exposed to it. But there is still room for more participation by heterodox researchers.
