- BACKGROUND: More refined information on sources of symptom-induced distress in a patient population can improve the quality of pretreatment information, make follow-up visits more efficient and guide research priorities in the efforts to modify treatments.METHODS: In a population-based epidemiological study covering all of Sweden, data were collected 1996-97 by means of an anonymous postal questionnaire. We attempted to enroll all 332 patients with stage IB-IIA cervical cancer registered in 1991-92 at the seven departments of gynecological oncology in Sweden.RESULTS: A total of 256 cases (77%) completed the questionnaire. After surgery, alone or in combination with intracavitary radiotherapy, several symptoms related to sexual dysfunction are the primary sources of symptom-induced distress (reduced orgasm frequency: much distress 23% (surgery alone) and 23% (intracavitary radiotherapy and surgery), respectively, overall intercourse dysfunction: much distress 17% and 20%, respectively, followed by lymphedema (much distress 14% and 14%, respectively). Dyspareunia (much distress 24%) and defecation urgency (much distress 22%) are two leading causes of distress after surgery and external radiotherapy. After treatment with radiotherapy alone, loose stool and dyspareunia were the two most distressful symptoms (much distress 19% each). When a symptom occurs, fecal leakage and reduced orgasm frequency are the two most distressful ones (measured as much distress, 38% each).CONCLUSIONS: The observed symptoms are distressful and should, if one focuses on patient satisfaction, be given priority.

- Abscission is an active process that enables plants to shed unwanted organs. Because the purpose of the flower is to facilitate pollination, it often is abscised after fertilization. We have identified an Arabidopsis ethylene-sensitive mutant, inflorescence deficient in abscission (ida), in which floral organs remain attached to the plant body after the shedding of mature seeds, even though a floral abscission zone develops. The IDA gene, positioned in the genomic DNA flanking the single T-DNA present in the ida line, was identified by complementation. The gene encodes a small protein with an N-terminal signal peptide, suggesting that the IDA protein is the ligand of an unknown receptor involved in the developmental control of floral abscission. We have identified Arabidopsis genes, and cDNAs from a variety of plant species, that encode similar proteins, which are distinct from known ligands. IDA and the IDA-like proteins may represent a new class of ligands in plants

- The use of fluorescence and reflectance spectroscopy in the analysis of cervical histopathology is a growing field of research. The majority of this research is performed with point-like probes. Typically, clinicians select probe sites visually, collecting a handful of spectral samples. An exception to this methodology is the Hyperspectral Diagnostic Imaging (HSDI®) instrument developed by Science and Technology International. This non-invasive device collects contiguous hyperspectral images across the entire cervical portio. The high spatial and spectral resolution of the HSDI instruments make them uniquely well suited for addressing the issues of coupled spatial and spectral variability of tissues in vivo. Analysis of HSDI data indicates that tissue spectra vary from point to point, even within histopathologically homogeneous regions. This spectral variability exhibits both random and patterned components, implying that point monitoring may be susceptible to significant sources of noise and clutter inherent in the tissue. We have analyzed HSDI images from clinical CIN (cervical intraepithelial neoplasia) patients to quantify the spatial variability of fluorescence and reflectance spectra. This analysis shows the spatial structure of images to be fractal in nature, in both intensity and spectrum. These fractal tissue textures will limit the performance of any point-monitoring technology.

- Study Design. Prospective follow-up.Objective. To describe the 5-year clinical course in a cohort of patients treated for back or neck pain in primary care and compare results with the 1-year outcome both for the whole group and for subgroups.Summary of Background Data. A randomized study showed a decrease in perceived pain and disability after treatment by chiropractic or physiotherapy, but many reported recurrence or continual pain at the 1-year follow-up. Knowledge of the clinical course over longer follow-up periods is limited.Methods. A 5-year follow-up questionnaire was sent to 314 individuals. Main outcome measures were pain intensity, Oswestry score, and general health. Recurrence, health care consumption, and other measures were described.Results. Fifty-two percent of respondents reported pain (visual analog scale, >10 mm) and back-related disability (Oswestry, >10%) at the 5-year follow-up. This was similar to 1-year results, and 84% of these were the same individuals. Sixty-three percent reported recurrence or continual pain, and 32% reported health care consumption at the 5-year follow-up.Conclusions. In a cohort of individuals of working age seeking primary care for nonspecific back or neck pain, it can be expected that about half of the population will report pain and disability at the 5-year follow-up. A significant proportion will report recurrence or continual pain and health care consumption. Pain and disability were associated with recurrence or continual pain and health care consumption. Further analysis is needed to identify additional predictors for 5-year outcome, taking into account 1-year follow-up results. Since many patients will have recurrence or continual pain, health policies and clinical decision models for long-term outcome must allow for these aspects.

- OBJECTIVE: To describe physical measures used in patients with back pain when no specific treatment is given, to examine associations between change over time in these measures and changes in pain and back-related disability, and to study the value of physical measures at baseline and at a 4-week follow-up to predict outcome at 12 months.DESIGN: A prospective consecutive study.SUBJECTS: Forty-four patients presenting with low back pain in primary care.METHODS: The patients underwent a physical examination at baseline and at 4 weeks. Follow-up was carried out using questionnaires until 12 months. Linear regression was used to identify predictors.RESULTS: Most measures had improved significantly at the 4-week follow-up. Thoracolumbar rotation, isometric endurance back extensors, and fingertip-to-floor distance at 4 weeks were significant predictors for pain intensity and back-related disability at the 12-month follow-up. Eighteen out of 44 patients reported an increase in pain after the assessment of the physical measures at baseline. This group of patients improved more in physical measures between baseline and the 4-week follow-up.CONCLUSION: Physical measures assessed at the 4-week follow-up, but not at baseline, could provide important additional information for identifying those patients at risk for worse outcome in pain or back-related disability at 12 months.

- The fragmentation dynamics of the SF6 molecule following the excitations of S 2p electrons into unoccupied molecular orbitals has been studied using the energy-resolved electron-ion coincidence technique. Fragmentation patterns were found to depend on the particular excitation and on the electronic state of the molecular ion. The spectator resonant Auger decay at the 2p --> 6a(1g) resonance induces changes in the ion distributions as compared to direct photoionization. Furthermore, coincidence spectra related to the same Auger structure display different ion abundances at the 2t(2g) and 4e(g) shape resonances. Differences were also found in the Auger decay spectra. These findings give further support for the previously suggested many-electron character of the 4e(g) shape resonance.

- Phenotypic and phylogenetic studies were performed on seven unidentified Gram-negative, facultatively anaerobic, coccobacillus-shaped organisms isolated from human clinical specimens. Comparative 16S rRNA gene sequencing demonstrated that four of the strains corresponded to Dysgonomonas capnocytophagoides whereas the remaining three isolates represent a new sub-line within the genus Dysgonomonas, displaying greater than 5% sequence divergence with Dysgonomonas capnocytophagoides and Dysgonomonas gadei. The three novel isolates were readily distinguished from D.capnocytophagoides and D. gadei by biochemical tests. The DNA base composition of the novel species was consistent with its assignment to the genus Dysgonomonas. Based on phylogenetic and phenotypic evidence it is proposed that the unknown species, be classified as Dysgonomonas mossii sp. nov. The type strain of Dysgonomonas mossii is CCUG 43457T (= CIP 107079T).

- PURPOSE: The purpose of this study was to analyze whether gene expression levels of folate enzymes in adjacent mucosa were associated with outcome of colorectal cancer patients. EXPERIMENTAL DESIGN: Real-time PCR was used to quantify expression levels of folate-associated genes including the reduced folate carrier (RFC-1), folylpolyglutamate synthase (FPGS), gamma-glutamyl hydrolase (GGH),and thymidylate synthase (TS) in tumor tissue and adjacent mucosa of patients with primary colorectal cancer (n=102). Furthermore, reduced folates in the tissues were measured with a binding-assay method. RESULTS: Mean gene expression levels of RFC-1, FPGS, GGH, and TS were significantly higher in tumor biopsies compared with mucosa. Univariate and multivariate analyses showed that the FPGS gene expression level in mucosa, but not in tumor, was a prognostic parameter independent of the clinicopathological factors with regard to survival. Patients with high FPGS levels (>0.92) in mucosa also showed significantly higher total folate concentrations (P=0.03) and gene expression levels of RFC-1 (P<0.01), GGH (P<0.01), and TS (P=0.04) compared with patients with low FPGS levels. The total reduced folate concentration correlated with the gene expression levels of RFC-1 and FPGS but not with TS or GGH. CONCLUSION: Our results suggest that normal-appearing colonic mucosa adjacent to primary colon cancer can show altered gene expression levels of FPGS that may have bearing on the development of aggressive metastatic behavior of the tumor and on tumor-specific survival.
