Long-term in vivo expression of the human glucocerebrosidase gene in nonhuman primates after CD34+ hematopoietic cell transduction with cell-free retroviral vector preparations.

Successful gene transfer into stem cells would provide a potentially useful therapeutic modality for treatment of inherited and acquired disorders affecting hematopoietic tissues. Coculture of primate bone marrow cells with retroviral producer cells, autologous stroma, or an engineered stromal cell line expressing human stem cell factor has resulted in a low efficiency of gene transfer as reflected by the presence of 0.1-5% of genetically modified cells in the blood of reconstituted animals. Our experiments in a nonhuman primate model were designed to explore various transduction protocols that did not involve coculture in an effort to define clinically useful conditions and to enhance transduction efficiency of repopulating cells. We report the presence of genetically modified cells at levels ranging from 0.1% (granulocytes) to 14% (B lymphocytes) more than 1 year following reconstitution of myeloablated animals with CD34+ immunoselected cells transduced in suspension culture with cytokines for 4 days with a retrovirus containing the glucocerebrosidase gene. A period of prestimulation for 7 days in the presence of autologous stroma separated from the CD34+ cells by a porous membrane did not appear to enhance transduction efficiency. Infusion of transduced CD34+ cells into animals without myeloablation resulted in only transient appearance of genetically modified cells in peripheral blood. Our results document that retroviral transduction of primate repopulating cells can be achieved without coculture with stroma or producer cells and that the proportion of genetically modified cells may be highest in the B-lymphoid lineage under the given transduction conditions.

Clinical Implications for Working with Gay Men A Self Psychological Treatment Approach.

Specific training for conducting psychotherapy with gay men is limited for psychologists, particularly when using a Self Psychology theoretical orientation (Robertson, 1996). In fact, psychologists often are faced with conflicting and contradictory points of view that mirror society's condemnation of homosexuality (Robertson, 1996). This paper is written from a self-psychological perspective to address the lack of a constructive body of literature that explains the unique treatment needs which impact gay men. Estimates of the prevalence of male homosexuality have generated considerable debate. A common assumption is that there are homosexual and non-homosexual men. However, scientists have long been aware that sexual responsiveness to others of the same sex, like most human traits, is continuously distributed in the population (Michaels, 1996). Still the presumption exists that such traits are stable within each man over time (Michaels, 1996). Conflating same-sex sexual experiences with a categorization of the man as homosexual is problematic, in that defining sexuality solely on the basis of experience excludes people who fantasize about sex with others of the same sex but never have sexual contact. Thus, most modern conceptions of sexual orientation consider personal identification, sexual behavior, and sexual fantasy (McWhirter, Sanders & Reinisch, 1990). Gay men's mental health can only be understood in the context of homosexuality throughout history, since religious and moral objections to sexual attraction between men have existed for centuries. Men who desired other men were regarded as sinful and depraved if not ill or abnormal, and same sex contacts were not distinguished from lewd behaviors (Weeks, 1989). Although most people, regardless of sexual orientation, have experienced some feelings of personal rejection, rarely do heterosexuals become targets for disapproval based on the nature of their attractions and behaviors relative to the same and to the other sex. For lesbians, bisexuals, and gay men, however, homosexuality becomes the focus of aspects of themselves that make them feel hated and hateful (Isay, 1989). While gay men and lesbians are often considered together because of the same-sex nature of their relationships and the similar issues that they may experience in their treatment within society, there are many issues where they might be best studied separately. Issues involving with health, parenthood, sexuality and perceived roles and status in society, for example, are often related more to gender than to any shared concept of a 'gay and lesbian community'. Many issues surrounding lesbians and lesbian culture will have more to do with women's issues, and some issues involving with gay men will have more to do with the gay male subculture and with masculinity. The author of this paper has limited experience in working with lesbian and bisexual individuals, and although it is likely that some of the concepts articulated in this paper could translate to working with lesbian and bisexual individuals, further research is indicated to examine the beneficence of utilizing a Self Psychological orientation in psychotherapy with lesbian women and bisexual individuals. This paper presents an overview of the literature including historical treatments of homosexuality, the history of Self Psychology, key principles in Self Psychology, research on Self Psychology, identity development models for gay men, and Self Psychological perspectives on identity development related to gay men. The literature review is followed by a section on treatment implications for psychologists seeking to treat gay men, including case vignettes based on work from my own practice. I have preserved the anonymity of clients by changing demographics, and rearranging and combining presenting issues and historical backgrounds among the case examples.

The Role of Hope in Rehabilitation and Long-term Outcomes among patients with Comorbid Spinal Cord and Traumatic Brain Injuries.

Spinal cord injury (SCI) and traumatic brain injury (TBI) are two potentially devastating conditions alone; when they co-occur in an individual they can be doubly so. The role of hope in rehabilitating oneself and recovering emotionally is examined in this paper. More specifically, Snyder's Model of Hope (1991) is examined as a tool that can aid in the rehabilitative process and help treatment providers, their patients, and the families of patients keep hope alive during a time of physical and emotional upheaval. This paper further examines the roles of hope in a rehabilitation program at Craig Hospital, a private, non-profit hospital dedicated exclusively to the rehabilitation of SCIs and TBIs and designated as a TBI and SCI Model Systems Center.

The Eating Disorder Inventory-III Maturity Fears Scale and Treatment Outcome in an Intensive Outpatient Eating Disorder Program

Eating disorders present a significant physical and psychological problem with a prevalence rate of approximately six percent in the United States. Despite the extensive literature, identifying the consistent risk factors for predicting the course of treatment in eating disorders remains difficult. The present study explores the use of a standardized assessment, using the consistently validated Eating Disorder Inventory-III (EDI-3), in predicting treatment outcome. Specifically, the study investigates the particular scale of Maturity Fears (MF) on the EDI-3, hypothesizing that higher scores on the MF scale would predict lower rates of recovery and treatment completion. The participants were 52 eating disorder patients (19 AN, 18 BN, and 15 EDNOS), consecutively admitted to a five-month long intensive outpatient program (IOP). The participants completed an EDI-3 self-report at pre and post treatment, and their score on the MF scale did not show a significant predictive relationship to treatment completion or change in symptoms, as measured by the Eating Disorder Risk Composite (EDRC) scale on the EDI-3. This finding primarily suggests that maturity fears are not a significant predictive factor in an outpatient setting with adults, as compared to previous studies that found a relationship between maturity fears and treatment outcome, primarily with adolescent and inpatient populations.

Steam reforming of ethanol over bimetallic RhPt/La2O3: Long-term stability under favorable reaction conditions

Recently, the steam reforming of biofuels has been presented as a potential hydrogen source for fuel cells. Because this scenario represents an interesting opportunity for Colombia (South America), which produces large amounts of bioethanol, the steam reforming of ethanol was studied over a bimetallic RhPt/La2O3 catalyst under bulk mass transfer conditions. The effect of temperature and the initial concentrations of ethanol and water were evaluated at space velocities above 55,000 h−1 to determine the conditions that maximize the H2/CO ratio and reduce CH4 production while maintaining 100% conversion of ethanol. These requirements were accomplished when 21 mol% H2O and 3 mol% C2H5OH (steam/ethanol molar ratio = 7) were reacted at 600 °C. The catalyst stability was assessed under these reaction conditions during 120 h on stream, obtaining ethanol conversions above 99% during the entire test. The effect of both H2 and air flows as catalyst regeneration treatments were evaluated after 44 and 67 h on stream, respectively. The results showed that H2 treatment accelerated catalyst deactivation, and air regeneration increased both the catalyst stability and the H2 selectivity while decreasing CH4 generation. Fresh and spent catalyst samples were characterized by TEM/EDX, XPS, TPR, and TGA. Although the Rh and Pt in the fresh catalyst were completely reduced, the spent samples showed a partial oxidation of Rh and small amounts of carbonaceous residue. A possible Rh–Pt–Rh2O3 structure was proposed as the active site on the catalyst, which was regenerated by air treatment.

Odell, Richard, 2 autographed letters signed to John Winthrop; Southampton, Long Island, 1652 November 16-1653

Correspondence concerning an illness, which Odell believed was palsy or the King's evil (scrofula), that afflicted his five-year-old daughter. Odell writes that her symptoms included loss of speech and feeling in her right side, and a throat blockage, and he requests advice from Winthrop on the course of treatment the family should pursue. Odell writes again in 1653 thanking Winthrop for the ointment and electuary he had prescribed for the child. Her symptoms had persisted, however, and he requested further advice. Odell adds several lines regarding rumors of an insurrection of a Native American tribe, inquiring if Winthrop has any information regarding "how matters stand & between the Dutch & the English."

Second St. Gallen European Organisation for Research and Treatment of Cancer Gastrointestinal Cancer Conference: consensus recommendations on controversial issues in the primary treatment of rectal cancer

Primary treatment of rectal cancer was the focus of the second St. Gallen European Organisation for Research and Treatment of Cancer (EORTC) Gastrointestinal Cancer Conference. In the context of the conference, a multidisciplinary international expert panel discussed and voted on controversial issues which could not be easily answered using published evidence. Main topics included optimal pretherapeutic imaging, indication and type of neoadjuvant treatment, and the treatment strategies in advanced tumours. Here we report the key recommendations and summarise the related evidence. The treatment strategy for localised rectal cancer varies from local excision in early tumours to neoadjuvant radiochemotherapy (RCT) in combination with extended surgery in locally advanced disease. Optimal pretherapeutic staging is a key to any treatment decision. The panel recommended magnetic resonance imaging (MRI) or MRI + endoscopic ultrasonography (EUS) as mandatory staging modalities, except for early T1 cancers with an option for local excision, where EUS in addition to MRI was considered to be most important because of its superior near-field resolution. Primary surgery with total mesorectal excision was recommended by most panellists for some early tumours with limited risk of recurrence (i.e. cT1-2 or cT3a N0 with clear mesorectal fascia on MRI and clearly above the levator muscles), whereas all other stages were considered for multimodal treatment. The consensus panel recommended long-course RCT over short-course radiotherapy for most clinical situations where neoadjuvant treatment is indicated, with the exception of T3a/b N0 tumours where short-course radiotherapy or even no neoadjuvant therapy were regarded to be an option. In patients with potentially resectable tumours and synchronous liver metastases, most panel members did not see an indication to start with classical fluoropyrimidine-based RCT but rather favoured preoperative short-course radiotherapy with systemic combination chemotherapy or alternatively a liver-first resection approach in resectable metastases, which both allow optimal systemic therapy for the metastatic disease. In general, proper patient selection and discussion in an experienced multidisciplinary team was considered as crucial component of care.

Secondary prevention of cardiovascular events with long-term pravastatin in patients with diabetes or impaired fasting glucose - Results from the LIPID trial

OBJECTIVE- Diabetes, a major health problem worldwide, increases the risk of cardiovascular disease and its associated mortality. Evidence of the overall benefits of lipid modification in this area is needed. RESEARCH DESIGN AND METHODS- The Long-Term Intervention with Pravastatin in Ischemic Disease (LIPID) trial showed that cholesterol-lowering treatment with pravastatin reduced mortality and coronary heart disease (CHD) events in 9,014 patients aged 31-75 years with CHD and total cholesterol 4.0-7.0 mmol/l. We measured the effects of pravastatin therapy, 40 mg/day over 6.0 years, on the risk of CHD death or nonfatal myocardial infarction and other cardiovascular outcomes in 1,077 LIPID patients with diabetes and 940 patients with impaired fasting glucose (IFG). RESULTS- in patients allocated to placebo, the risk of a major CHD event was 61% higher in patients with diabetes and 23% higher in the IFG group than in patients with normal fasting glucose, and the risk of any cardiovascular event was 37% higher in the diabetic group and 19% higher in the IFG group. Pravastatin therapy reduced the risk of a major CHD event overall from 15.9 to 12.3% (relative risk reduction [RRR] 24%, P < 0.001) and from 23.4 to 19.6% in the diabetic group (19%, P = 0.11); in the diabetic group, the reduction was not significantly different from the reductions in the other groups. Pravastatin reduced the risk of any cardiovascular event from 52.7 to 45.2% (21%, P < 0.008) in patients With diabetes and from 45.7 to 37.1% (26%, P = 0.003) in the IFG group. Pravastatin reduced the risk of stroke from 9.9 to 6.3% in the diabetic group (RRR 39%, Cl 7-61%, P = 0.02) and from 5.4 to 3.4% in the IFG group (RRR 42%, Cl -9 to 69%, P = 0.09). Pravastatin did not reduce the incidence of diabetes. Over 6 years, pravastatin therapy prevented one major,CHD event (CHD death or nonfatal myocardial infarction) in 23 patients with IFG and 18 patients with diabetes. A meta-analysis of other major trials confirmed the high absolute risks of diabetes and IFG and the absolute benefits of statin therapy in these patients. CONCLUSIONS- Cholesterol-lowering treatment with pravastatin therapy prevents cardiovascular events, including stroke, in patients with diabetes or IFG and established CHD.

Plasma concentrations of tafenoquine, a new long-acting antimalarial agent, in Thai soldiers receiving monthly prophylaxis

We measured plasma tafenoquine concentrations in Thai soldiers given a monthly regimen of tafenoquine to determine whether these concentrations adequately suppressed malarial infections on the Thai- Cambodian border. After receiving a treatment course of artesunate and doxycycline, 104 male soldiers were administered a loading dose of tafenoquine ( 400 mg daily for 3 days), followed by tafenoquine monthly ( 400 mg every 4 weeks) for 5 months. Consecutive monthly mean ( +/- standard deviation) trough plasma tafenoquine concentrations were 223 +/- 41, 127 +/- 29, 157 +/- 51. 120 +/- 24, and 88 +/- ng/ mL. Only 1 soldier developed malaria during the study. At the time of malaria diagnosis, his plasma tafenoquine concentration was 40 ng/ mL, which was similar to 3- fold lower than the trough concentrations of the other soldiers. Although low tafenoquine concentrations appear to be uncommon, additional investigations are needed to determine the relationship between plasma tafenoquine concentrations and suppression of malaria.

Treatment delays in paediatric dento-alveolar trauma at a tertiary referral hospital

Background: Paediatric dento-alveolar trauma is a common event. Delays in treatment can have adverse effects on long term outcomes and the aim of this study was to quantify the treatment delays in paediatric dento-alveolar trauma in a tertiary referral hospital. Methods: All cases of paediatric dento-alveolar trauma over a two-year period from July 2000 to June 2002 were identified and the charts were reviewed retrospectively. All children presenting the emergency department with dento-alveolar trauma within 48 hours of injury during the time period were included. Results: Forty-three patients were identified. The average age was 5.51 years, though there was a bias towards one and two year olds. Males were injured 1.5 times more frequently than females. There was an average delay of 9.6 hours between injury and treatment for all patients. Transit time from outside practitioners to hospital and waiting times in hospital made up the greatest delays. Children injured an average of 2.37 teeth and only 14 per cent were uncomplicated crown fractures. Conclusions: Children who present to children's hospitals for treatment of dento-alveolar trauma have more severe injuries than those treated elsewhere. They have large but potentially reducible delays between injury and treatment.
