Sustained biochemical remission after interferon treatment may closely be related to the end of treatment biochemical response and associated with a lower incidence of hepatocarcinogenesis

LIVER INTERNATIONAL, Issue 3 2003

Abstract: Clinical background and incidence of hepatocellular carcinoma (HCC) of patients with chronic hepatitis C who obtained biochemical remission without eradication of virus (biochemical response) after interferon (IFN) treatment was retrospectively analyzed for 755 patients. Annual incidence of HCC was significantly lower in the patients with biochemical response and sustained response than that of the patients that did not show these responses. Logistic regression analysis showed that only the normalization of alanine aminotransferase (ALT) value at the end of IFN treatment was a significant factor for biochemical response. Annual incidence of HCC was significantly lower in the patients who obtained normalization of ALT values at the end of treatment than those who did not. Patients who were younger, who had a lower level of activity and fibrosis indices in histology, higher platelet count, and who were given more higher total dose of IFN were more likely to attain normalization of ALT levels at the end of treatment, and this was related to biochemical response. Low incidence of HCC in patients who obtained normalization of ALT values at the end of treatment was likely because they were in the earlier stage of chronic hepatitis. Active treatment of chronic hepatitis C with interferon in the early phase of the disease may bring about a biochemical response in some patients, even if sustained virological response is not obtained.

THE MOLECULAR FUTURE IN CYTOLOGY

CYTOPATHOLOGY, Issue 2006
M. Salto-Tellez
Molecular diagnosis is the application of molecular biology techniques and knowledge of the molecular mechanisms of disease to diagnosis, prognostication and treatment of diseases. Molecular Diagnosis is, arguably, the fastest growing area of diagnostic medicine. The US market for molecular testing generated $1.3 billion in 2000, which was predicted to increase to about $4.2 billion by 2007.1 We proposed the term Diagnostic Molecular Cytopathology to define the application of molecular diagnosis to cytopathology2. Diagnostic Molecular Cytopathology is essential for the following reasons: (i) Molecular testing is sometimes indispensable to establish an unequivocal diagnosis on cell preparations; (ii) Molecular testing provides extra information on the prognosis or therapy of diseases diagnosed by conventional cytology; (iii) Molecular testing provides genetic information on the inherited nature of diseases that can be directly investigated in cytology samples, by either exfoliation or by fine needle aspiration; (iv) Sometimes the cytopathology sample is the most convenient (or the only available) source of material for molecular testing; (v). Direct molecular interrogation of cells allows for a diagnostic correlation that would otherwise not be possible. Parallel to this direct diagnostic implication, cytopathology is increasing important in the validation of biomarkers for specific diseases, and in therefore of significant importance in the overall translational research strategies. We illustrate its application in some of the main areas of oncology molecular testing, such as molecular fingerprinting of neoplasms,3 lymphoreticular diseases,2 sarcomas4 and lung cancer,5 as well as translational research using diagnostic cytopathology techniques. The next years will see the consolidation of Diagnostic Molecular Cytopathology, a process that will lead to a change of many paradigms. In general, diagnostic pathology departments will have to reorganize molecular testing to pursue a cost-efficient operation. Sample preparation will have to take into account optimal preservation of nuclear acids. The training of technical staff and the level of laboratory quality control and quality assurance would have to follow strict clinical (not research) laboratory parameters. And, most importantly, those pathologists undertaking molecular diagnosis as a discipline would have to develop their professional expertise within the same framework of fellowships and professional credentials that is offered in other sub-specialties. The price to pay if this effort is not undertaken is too important for the future of diagnostic pathology in general. The increasing characterization of molecular biomarkers with diagnostic, prognostic or therapeutic value is making the analysis of tissue and cell samples prior to treatment a more complex exercise. If cytopathologists and histopathologists allow others to take charge of molecular diagnosis, our overall contribution to the diagnostic process will be diminished. We may not become less important, but we may become less relevant. However, those within the discipline of diagnostic pathology who can combine the clinical background of diseases with the morphological, immunocytochemical and molecular diagnostic interpretation will represent bona fide diagnostic specialists. Such ,molecular cytopathologists' would place themselves at the centre of clinical decision-making. Reference:, 1. Liz Fletcher. Roche leads molecular diagnostics charge.

Psychiatric morbidity among patients with cancer of the esophagus or the gastro-esophageal junction: a prospective, longitudinal evaluation

DISEASES OF THE ESOPHAGUS, Issue 6 2007
H. Bergquist
SUMMARY., Cancer of the esophagus is often diagnosed at a late stage and is related to severe morbidity and a low 5-year survival rate. Previous studies have reported low health-related quality of life and high suicide rates for these patients. The occurrence of psychiatric morbidity and thus the potential need for psychological support may vary over time after diagnosis. This has not been adequately studied in patients with newly diagnosed cancer of the esophagus or gastro-esophageal junction. The present study therefore aimed to prospectively evaluate the prevalence of psychiatric morbidity in 94 consecutive patients (median age 66, range 45,88 years) with all stages of disease. Psychiatric morbidity was evaluated with the Hospital Anxiety and Depression Scale (HADS) questionnaire at inclusion and 1, 2, 3, 6 and 12 months later. At inclusion, 42% of the patients had HADS scores indicating possible or probable anxiety disorder and/or depression. At all follow-ups except at 3 months, proportions of patients with possible/probable anxiety disorder were significantly lower than at inclusion. Among patients with a duration of tumor-specific symptoms exceeding 6 months pre-diagnosis, larger proportions of patients with a possible/probable anxiety disorder were found at the 1- and 6-month follow ups. The prevalence of possible/probable depression was greater among patients treated with a palliative intent than among those with a curative intent at inclusion. Patients who died during the study period scored worse for depression compared to the survivors. Apart from this, the proportion of patients with possible/probable psychiatric morbidity (anxiety and/or depression) was relatively stable over time and was unrelated to patient characteristics or clinical background, including the treatment regime. In conclusion, psychiatric morbidity is common among esophageal cancer patients, both at inclusion and over time, regardless of the cancer therapy given. The findings stress the importance of monitoring the patients' mental health and of offering adequate psychological care when needed. [source]


Save the Young,the Elderly Have Lived Their Lives: Ageism in Marriage and Family Therapy,

FAMILY PROCESS, Issue 2 2000
David C. Ivey Ph.D.
The paucity of literature addressing mental health issues concerning geriatric populations represents the perpetuation of ageist practices and beliefs in the field of marriage and family therapy. The purpose of this study was to assess whether client age and clinical training relate to the evaluation of couples who present for conjoint therapy. Written vignettes describing two couples, one older and one younger, who report issues involving the absence of sexual intimacy, increased frequency of arguments, and increased use of alcohol were evaluated by practicing marriage and family therapists, therapists-in-training, and individuals with no clinical background. It was hypothesized that respondents' views would vary in connection with the age of the couple and with the three levels of participant training. Results indicate that client age and participant training are associated with perceptions of individual and couple functioning. Our findings suggest that the relational and mental health concerns experienced by elder couples are not perceived as seriously as are identical concerns experienced by younger couples. Contrary to our expectations the observed differences between views of the two age conditions did not significantly differ between levels of participant training. Training and experience in marriage and family therapy may not significantly mitigate vulnerability to age-discrepant views. [source]


Clinical characteristics of normotensive renal transplant recipients with microalbuminuria and effects of angiotensin II type I receptor antagonist on urinary albumin excretion

INTERNATIONAL JOURNAL OF UROLOGY, Issue 8 2004
SHIGERU SATOH
Abstract Aim:, Microalbuminuria is typically observed in renal transplant recipients with systemic hypertension. The effects of angiotensin II type 1 receptor antagonist (losartan) on the hypertensive recipients have been evaluated. However, the clinical background of normotensive recipients with microalbuminuria and the effect of losartan administration in those subjects have not been clarified. One of the two purposes for the present study was to investigate the clinical characteristics of normotensive recipients with microalbuminuria. The other was to evaluate the effect of losartan on urinary excretion of albumin in these patients. Methods:, The clinical data and the change of the single kidney glomerular filtration rate (GFR) for the graft by radionuclide study were assessed in 13 normotensive recipients with microalbuminuria. These were compared with the data of 13 normotensive patients without microalbuminuria. The 13 recipients with microalbuminuria were treated with losartan for one year and urine excretion of albumin, N-acetyl-,-D-glucosaminidase (NAG) and serum creatinine (S-Cr) levels were measured. Results:, The GFR of the grafts from donors to recipients significantly increased (30.9 to 55.2 mL/min) in microalbuminuric recipients, but did not significantly increase in the non-microalbuminuric recipients. Decreases of the urinary excretion rate of albumin (351 ± 261 at baseline to 158 ± 14 mg/gCr at 12 months), NAG (13 ± 5 to 10 ± 3 IU/gCr) and S-Cr (1.7 ± 0.6 to 1.5 ± 0.4 mg/dL) were observed in the microalbuminuric recipients with losartan administration. Conclusions:, The present study suggests that an increased single kidney GFR of the graft from the donor in situ to the recipient might be a cause of microalbuminuria in normotensive recipients. The one-year effects of losartan were observed in terms of the decrease in urinary excretion of albumin, NAG and S-Cr levels. [source]

Aliment Pharmacol Ther,31, 407,414 Summary Background, The surveillance of hepatocellular carcinoma (HCC) has become prevalent, and the modalities for its treatment have improved. Aim, To understand the changes that occur in the characteristics and prognostic factors of HCC with time. Methods, Newly diagnosed HCC patients were divided into two groups; patients treated before 31 December 2000 (n = 504), and after 1 January 2001 (n = 746), and their clinical backgrounds and prognostic factors were analysed. Results, The number of patients negative for both Hepatitis B surface antigen (HBsAg) and Hepatitis C virus antibody (HCVAb) increased with time (NBNC-HCC). The size of HCC decreased in patients who were positive for HBsAg (B-HCC) or HCVAb (C-HCC), whereas no difference was observed in NBNC-HCC. The patient survival of C-HCC improved; however, no difference was detected for NBNC-HCC. In multivariate analysis, low albumin, high aspartate aminotransferase (AST), ascites, large tumour size, multiple tumour number and high alpha-fetoprotein were risk factors for survival before 2000, whereas the presence of HBsAg was additionally selected as a good prognostic factor and AST was excluded after 2001. Conclusions, The prognostic factors as well as clinical background of HCC changed with time, and the presence of HBsAg was found to be an additional good prognostic factor after 2001. [source]


Cartilage tissue engineering using resorbable scaffolds

JOURNAL OF TISSUE ENGINEERING AND REGENERATIVE MEDICINE, Issue 6 2007
Nicole Rotter
Abstract Cartilage tissue engineering holds considerable promise for orthopaedic and reconstructive head and neck surgery. With an increasingly ageing population, the number of patients affected by arthritis and recurrent joint pain is constantly growing, along with the associated socio-economic costs. In head and neck surgery reconstructive procedures gain increasing importance in multimodal tumour therapies. These procedures require the harvesting of large amounts of donor tissue, which causes significant donor site morbidity. Therefore, in vitro -engineered cartilage may provide for a cost-effective and clinically valuable medical need. This article presents an overview of the clinical background as well as considerations for engineered cartilage in the head and neck, and provides examples of cartilage tissue engineering based on various scaffolds.

Risk axis: Implementation of structured clinical guidelines for the assessment and management of risk in psychiatry

ASIA-PACIFIC PSYCHIATRY, Issue 2 2009
Shailesh Kumar FRANZCP MRCPsych
Abstract Introduction: Mental health clinicians routinely assess risk in three domains: suicide, violence and self neglect. While the published work on the assessment of these risks has increased, concerns are often expressed that assessment alone does not lead to management of the identified risk. Not all axes of multiaxial classificatory systems are used by clinicians to the same extent, despite their proven usefulness. It is possible that a dedicated axis for risk management as a part of a multiaxial classificatory system could align risk assessment with management and increase utility of multiaxial classificatory systems. Methods: Based on our earlier work we developed a comprehensive risk management axis (RMA), which was then further refined by conducting a pilot study and then used to collect data retrospectively from the case notes of 100 patients consecutively discharged from a general psychiatric ward. Results: Common association between risk factors and three risk domains were as follows. Violence: active symptoms of major mental illness, employment problems, and major mental illness; Suicide: history of abuse, clinically significant depressive symptoms, and alcohol and drug use; Self neglect: neglect of home, personal safety, noncompliance with treatment, male gender, and low income. We also investigated whether the presence of a particular risk factor acted as a barrier or prompt for clinicians to address management factors in the RMA. Discussion: It is possible to assess risk across the three domains and to derive management plans by using the proposed RMA. Minimal clinical background is necessary for collecting data retrospectively. It should be possible to apply this axis prospectively. [source]

History for a practice profession

NURSING INQUIRY, Issue 4 2006
Patricia D'Antonio
This essay explores the meaning of history for a practice profession. It argues that our clinical backgrounds suggest particular kinds of historical questions that colleagues with different backgrounds would not think to ask. This essay poses three possible questions as examples. What if we place the day after day work of caring for the sick , that which is nursing , at the center of an institution's history? What if we were to embrace a sense of nurses and nursing work as truly diverse and different? What if we were to analytically engage the reluctance of the large number of nurses to formally embrace feminism? This essay acknowledges that these are not the only possible questions and, in the end, they most likely will not even be the important ones. But this essay does argue that we, who are both clinicians and historians, need to more seriously consider the implications of our questions for disciplinary practice and research. It argues, in the end, that the meaning of history to a practice profession lies in our questions: questions that are different than those raised by other methods, and questions that may escape notice in the press of daily practice and research.
