Abstract
AIM To describe diabetes nurses' perspectives on the impact of the COVID-19 pandemic on people with diabetes and diabetes services across Europe. METHODS An online survey developed using a rapid Delphi method. The survey was translated into 17 different languages and disseminated electronically in 27 countries via national diabetes nurse networks. RESULTS Survey responses from 1829 diabetes nurses were included in the analysis. The responses indicated that 28% (n = 504) and 48% (n = 873) of diabetes nurses felt the COVID-19 pandemic had impacted 'a lot' on the physical and psychological risks of people with diabetes, respectively. The following clinical problems were identified as having increased 'a lot': anxiety 82% (n = 1486); diabetes distress 65% (n = 1189); depression 49% (n = 893); acute hyperglycaemia 39% (n = 710) and foot complications 18% (n = 323). Forty-seven percent (n = 771) of respondents identified that the level of care provided to people with diabetes had declined either extremely or quite severely. Self-management support, diabetes education and psychological support were rated by diabetes nurse respondents as having declined extremely or quite severely during the COVID-19 pandemic by 31% (n = 499), 63% (n = 1,027) and 34% (n = 551), respectively. CONCLUSION The findings show that diabetes nurses across Europe have seen significant increases in both physical and psychological problems in their patient populations during COVID-19. The data also show that clinical diabetes services have been significantly disrupted. As the COVID-19 situation continues, we need to adapt care systems with some urgency to minimise the impact of the pandemic on the diabetes population.

Abstract
AIMS To investigate fear of hypoglycaemia (FoH) longitudinally in a cross-sectional study of adult patients with type 1 diabetes. Specifically, we investigated two subgroups of patients who over 4 years either showed a substantial increase or decrease in level of FoH to identify factors associated with changes in FoH. METHODS The Swedish version of the Hypoglycaemia Fear Survey (HFS) along with a questionnaire to assess hypoglycaemia history was sent by mail to 764 patients in 2010. The responders in 2010 (n = 469) received another set of the same two questionnaires in 2014. HbA1c, insulin regimen, weight and creatinine from 2010 and 2014 were obtained from medical records. Those with an absolute difference in HFS scores ≥ 75th percentile were included in the subgroup analyses. Statistical analyses included one-sample t tests, chi-square and McNemar's test. RESULTS The absolute difference in the HFS total score (n = 347) between 2010 and 2014 was m = ±7.6, SD ± 6. In the increased FoH group, more patients reported a high level of moderate hypoglycaemic episodes as well as impaired awareness of hypoglycaemia in 2014 compared with the decreased FoH group. There were more subjects in the increased FoH group with insulin pumps in 2014 and in 2010. In the decreased FoH group, more patients had a high frequency of daily self-monitoring of blood glucose (SMBG) in 2010 and in 2014. CONCLUSIONS Fear of hypoglycaemia is stable across time for most patients. Changes in fear level are associated with changes in hypoglycaemia frequency. Thus, asking patients about changes in hypoglycaemia experiences is of great importance.

Abstract
Definite progress has been made in the exploration of myelodysplastic syndromes (MDS) by flow cytometry (FCM) since the publication of the World Health Organization 2008 classification of myeloid neoplasms. An international working party initiated within the European LeukemiaNet and extended to include members from Australia, Canada, Japan, Taiwan and the United States has, through several workshops, developed and subsequently published consensus recommendations. The latter deal with preanalytical precautions, and propose small and large panels, which allow evaluating immunophenotypic anomalies and calculating myelodysplasia scores. The current paper provides guidelines that strongly recommend the integration of FCM data with other diagnostic tools in the diagnostic work-up of MDS.

Abstract
BACKGROUND AND PURPOSE More evidence is needed to forward our understanding of the key determinants of poor outcome after mild traumatic brain injury (MTBI). A large, prospective, national cohort of patients was studied to analyse the effect of head CT scan pathology on the outcome. METHODS One-thousand two-hundred and sixty-two patients with MTBI (Glasgow Coma Scale score 15) at 39 emergency departments completed a study protocol including acute head CT scan examination and follow-up by the Rivermead Post Concussion Symptoms Questionnaire and the Glasgow Outcome Scale Extended (GOSE) at 3 months after MTBI. Binary logistic regression was used for the assessment of prediction ability. RESULTS In 751 men (60%) and 511 women (40%), with a mean age of 30 years (median 21, range 6-94), we observed relevant or suspect relevant pathologic findings on acute CT scan in 52 patients (4%). Patients aged below 30 years reported better outcome both with respect to symptoms and GOSE as compared to patients in older age groups. Men reported better outcome than women as regards symptoms (OR 0.64, CI 0.49-0.85 for ≥3 symptoms) and global function (OR 0.60, CI 0.39-0.92 for GOSE 1-6). CONCLUSIONS Pathology on acute CT scan examination had no effect on self-reported symptoms or global function at 3 months after MTBI. Female gender and older age predicted a less favourable outcome. The findings support the view that other factors than brain injury deserve attention to minimize long-term complaints after MTBI.

Abstract
Flow cytometry (FC) is increasingly recognized as an important tool in the diagnosis and prognosis of myelodysplastic syndromes (MDS). However, validation of current assays and agreement upon the techniques are prerequisites for its widespread acceptance and application in clinical practice. Therefore, a working group was initiated (Amsterdam, 2008) to discuss and propose standards for FC in MDS. In 2009 and 2010, representatives from 23, mainly European, institutes participated in the second and third European LeukemiaNet (ELN) MDS workshops. In the present report, minimal requirements to analyze dysplasia are refined. The proposed core markers should enable a categorization of FC results in cytopenic patients as 'normal', 'suggestive of', or 'diagnostic of' MDS. An FC report should include a description of validated FC abnormalities such as aberrant marker expression on myeloid progenitors and, furthermore, dysgranulopoiesis and/or dysmonocytopoiesis, if at least two abnormalities are evidenced. The working group is dedicated to initiate further studies to establish robust diagnostic and prognostic FC panels in MDS. An ultimate goal is to refine and improve diagnosis and prognostic scoring systems. Finally, the working group stresses that FC should be part of an integrated diagnosis rather than a separate technique.

Abstract
OBJECTIVES To compare the preverbal communication skills of two groups of young implanted children: those with unilateral implantation and those with bilateral implantation. MATERIAL AND METHODS The study assessed 69 children: 42 unilaterally and 27 bilaterally implanted with age at implantation less than 3 years. The preverbal skills of these children were measured before and 1 year after implantation, using Tait Video Analysis that has been found able to predict later speech outcomes in young implanted children. RESULTS Before implantation there was no significant difference between the unilateral group and the bilateral group. There was still no difference at 12 months following implantation where vocal autonomy is concerned, but a strongly significant difference between the groups for vocal turn-taking and non-looking vocal turns, the bilateral group outperforming the unilateral group. Regarding gestural turn-taking and gestural autonomy, there was a strongly significant difference between the two groups at the 12 month interval, and also a difference before implantation for gestural autonomy, the unilateral group having the higher scores. Multiple regression of non-looking vocal turns revealed that 1 year following implantation, bilateral implantation contributed to 51% of the variance (p<0.0001), after controlling for the influence of age at implantation and length of deafness which did not reach statistical significance. CONCLUSIONS Profoundly deaf bilaterally implanted children are significantly more likely to use vocalisation to communicate, and to use audition when interacting vocally with an adult, compared with unilaterally implanted children. These results are independent of age at implantation and length of deafness.

Abstract
This chapter deals with non-vascular intracranial disorders resulting in headache. Headache attributed to high or low cerebrospinal fluid pressure is separated into headache attributed to idiopathic intracranial hypertension (IIH), headache attributed to intracranial hypertension secondary to metabolic, toxic, or hormonal causes, headache attributed to intracranial hypertension secondary to hydrocephalus, post-dural puncture headache, cerebrospinal fluid (CSF) fistula headache, headache attributed to spontaneous (or idiopathic) low CSF pressure. Headache attributed to non-infectious inflammatory disease can be caused by neurosarcoidosis, aseptic (non-infectious) meningitis or lymphocytic hypophysitis. Headache attributed to intracranial neoplasm can be caused by increased intracranial pressure or hydrocephalus caused by neoplasm or attributed directly to neoplasm or carcinomatous meningitis. Other causes of headache include hypothalamic or pituitary hyper- or hyposecretion and intrathecal injection. Headache attributed to epileptic seizure is separated into hemicrania epileptica and post-seizure headache. Finally headache attributed to Chiari malformation type I (CM1) and the syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis (HaNDL) are described.

Abstract
BACKGROUND Triple-negative breast cancer (TNBC) lacking expression of steroid receptors and human epidermal growth factor receptor 2, having chemotherapy as the only therapeutic option, is characterised by early relapses and poor outcome. We investigated intratumoural (i.t.) levels of the pro-angiogenic cytokine vascular endothelial growth factor (VEGF) and survival in patients with TNBC compared with non-TNBC. PATIENTS AND METHODS VEGF levels were determined by an enzyme immunosorbent assay in a retrospective series consisting of 679 consecutive primary breast cancer patients. RESULTS Eighty-seven patients (13%) were classified as TNBC and had significantly higher VEGF levels; median value in TNBC was 8.2 pg/microg DNA compared with 2.7 pg/microg DNA in non-TNBC (P < 0.001). Patients with TNBC had statistically significant shorter recurrence-free survival [hazard ratio (HR) = 1.8; P = 0.0023], breast cancer-corrected survival (HR = 2.2; P = 0.004) and overall survival (HR = 1.8; P = 0.005) compared with non-TNBC. Patients with TNBC relapsed earlier than non-TNBC; mean time from diagnosis to first relapse was 18.8 and 30.7 months, respectively. The time between first relapse and death was also shorter in TNBC: 7.5 months versus 17.5 months in non-TNBC (P = 0.087). CONCLUSIONS Our results show that TNBC have higher i.t. VEGF levels compared with non-TNBC. Ongoing clinical trials will answer if therapy directed towards angiogenesis may be an alternative way to improve outcome in this poor prognosis group.

Abstract
As breast volume may be associated with heart cancer risk, we studied the relationship between breast volume, CYP1A2*1F and coffee intake. Among healthy premenopausal non-hormone users, 3+ cups per day was associated with lower volume only in C-allele carriers (Pinteraction=0.02), which is consistent with reports that coffee protects only C-allele carriers against breast cancer.

Abstract
Natrium aurothiomaleate (GSTM) is a useful disease-modifying anti-rheumatic drug, but causes a variety of immune-mediated adverse effects in many patients. A murine model was used to study further the interaction of GSTM with the immune system, including induction of systemic autoimmunity. Mice were given weekly intramuscular injections of GSTM and controls equimolar amounts of sodium thiomaleate. The effects of gold on lymphocyte subpopulations were determined by flow cytometry. Humoral autoimmunity was measured by indirect immunofluorescence and immunoblotting, and deposition of immunoglobulin and C3 used to assess immunopathology. Gold, in the form of GSTM, stimulated the murine immune system causing strain-dependent lymphoproliferation and autoimmunity, including a major histocompatibility complex (MHC)-restricted autoantibody response against the nucleolar protein fibrillarin. GSTM did not cause glomerular or vessel wall IgG deposits. However, it did elicit a strong B cell-stimulating effect, including both T helper 1 (Th1)- and Th2-dependent isotypes. All these effects on the immune system were dependent on the MHC genotype, emphasizing the clinical observations of a strong genetic linkage for the major adverse immune reactions seen with GSTM treatment.

Abstract
The CYP17 gene is involved in steroid hormone metabolism and has been proposed as a low penetrance gene for breast cancer. We aimed to investigate the associations between the CYP17 genotype and breast cancer risk factors, such as age at menarche, menstrual cycle length, oral contraceptive (OC) use, and BRCA mutation status among 258 healthy young women, aged < or =40, from 158 breast cancer high-risk families. Questionnaires including questions on reproductive factors and OC use were completed and blood samples were obtained from all women. CYP17 (rs743572) was genotyped with sequencing in 254 women. The main findings were that short menstrual cycles (<27 days) were significantly more common with increasing number of variant A2 alleles (8%, 17% and 32%; P(trend) = 0.002, adjusted for family clustering). Each A2 allele was associated with a 7 months earlier OC start (17.8, 17.0, and 16.6 years; P(trend) = 0.014, adjusted for age at menarche, ever-smoking and family clustering). Homozygosity for the A2 allele was more common among known non-carriers from BRCA1/2 families compared with other high-risk women OR 2.92 (95% CI 1.49-5.73; P = 0.002, adjusted for family clustering). We found no association between CYP17 genotype and age at menarche. In conclusion, this study suggests that short menstrual cycles, age at first OC use and BRCA mutation status may need to be considered in studies exploring the relationships between CYP17 and risk factors for early onset breast cancer.

Abstract
Periodontal pathogenic bacteria are associated with elevated levels of interleukin-1alpha (IL-1alpha) but it is unclear if all species can induce cytokine production equally. Porphyromonas gingivalis may be able antagonize IL-1alpha induced by other species through the activity of its proteases or lipopolysaccharide (LPS). Monomac-6 cells and primary human monocytes were treated with culture supernatants from Porphyromonas gingivalis, Fusobacterium nucleatum, Campylobacter rectus, Actinobacillus actinomycetemcomitans, Prevotella intermedius, Veillonella atypical and Prevotella nigrescens. IL-1alpha protein levels were measured after 6 h of incubation. In addition, monocytes were co-stimulated with supernatants from P. gingivalis and other bacteria. The role of P. gingivalis proteases was tested using Arg-X and Lys-X mutant strains. The role of LPS was investigated using purified P. gingivalis LPS and polymixin depletion. All species tested induced significant IL-1alpha production, but P. gingivalis was the weakest. Co-stimulation of monocytes with P. gingivalis antagonized the ability of other bacterial species to induce IL-1alpha production. This effect was at its greatest with C. rectus (resulting in a 70% reduction). Gingipain mutant strains and chemical inhibition of protease activity did not reduce antagonistic activity. However, 100 ng/ml of P. gingivalis LPS can reproduce the antagonistic activity of P. gingivalis culture supernatants. Periodontitis-associated bacterial species stimulate IL-1alpha production by monocytes. P. gingivalis can antagonize this effect, and its LPS appears to be the crucial component. This study highlights the importance of mixed infections in the pathogenesis of periodontal disease because reduction of pro-inflammatory cytokine levels may impair the ability of the host to tackle infection.

Abstract
BACKGROUND To further improve the outcome of clinical islet transplantation analysis of the impact of donor- and process-related factors could be of great importance. MATERIALS AND METHODS Thirty-eight consecutive clinical islet transplantations were performed with consecutive islet isolations. Univariate analysis for donor- and isolation-related variables were correlated with recipient C-peptide levels at 2 and 4 weeks after transplantation. "Warm ischemia time" was defined as the time from start of University of Wisconsin solution perfusion in the donor until the pancreas was removed to the back table. RESULTS Short "warm ischemia time" (WIT), low expression of tissue factor (TF) in pancreatic tissue, and high creatinine levels in the donor were variables related to high C-peptide values after islet transplantation. Furthermore, hospitalization length longer than 4 days was associated with low C-peptide levels. The number of islet equivalents (IEQ) did not correlate with the clinical outcome, possibly due to the fact that IEQ number was included in the release criteria for clinical islet transplantation CONCLUSIONS Successful clinical islet transplantation is strongly correlated with donor and pancreas procurement factors rather than isolation process-related variables. "WIT" may induce TF expression in the pancreatic tissues. TF has been identified as the main trigger of the instant blood-mediated-inflammatory reaction in clinical islet transplantation. Therefore, assay of TF expression in pancreatic tissues could be applied as useful screening tool to identify "good" pancreata for clinical transplantation.

Abstract
The objective of this study was to investigate prospectively the associations between intakes of plant foods, fibre and relative fat and risk of breast cancer in a subsample of 11 726 postmenopausal women in the Malmö Diet and Cancer cohort. Data were obtained by an interview-based diet history method, a structured questionnaire, anthropometrical measurements and national and regional cancer registries. During 89 602 person-years of follow-up, 342 incident cases were documented. Cox regression analysis examined breast cancer risks adjusted for potential confounders. High fibre intakes were associated with a lower risk of postmenopausal breast cancer, incidence rate ratio=0.58, 95% CI: 0.40, 0.84, for the highest quintile of fibre intake compared to the lowest quintile. The combination high fibre–low fat had the lowest risk when examining the effect in each cell of cross-classified tertiles of fibre and fat intakes. An interaction (P=0.049) was found between fibre- and fat-tertiles. There was no significant association between breast cancer risk and intakes of any of the plant food subgroups. These findings support the hypothesis that a dietary pattern characterised by high fibre and low fat intakes is associated with a lower risk of postmenopausal breast cancer.

Abstract
We have previously shown that the CD47-binding thrombospondin-1 (TSP-1)-derived peptide 4N1K induces a rapid apoptosis-like death of human monocytes and dendritic cells (DCs). However, not all cells were susceptible to the peptide-induced cell death and here, we have investigated whether surviving monocytes could differentiate into functionally normal DCs. We found that the cell-surface phenotype, the T-cell stimulatory capacity and the ability to undergo lipopolysaccharide (LPS)-induced maturation into CD83+ DCs were essentially identical in 4N1K-derived and control DCs. Interleukin-10 (IL-10) production was also normal, but a significant downregulation of the pro-inflammatory cytokines IL-12 and tumour necrosis factor-alpha (TNF-alpha) was observed in the 4N1K-derived DCs. To the contrary, simultaneous stimulation of control DCs with 4N1K and LPS + interferon-gamma did not alter IL-12 production. These results indicate that although activation of the TSP-1-binding region of CD47 on monocytes induces apoptosis in a large proportion of the cells, it does not hamper the overall capacity of the surviving cells to differentiate into DCs. Such DCs, however, have a reduced capacity for IL-12 and TNF-alpha production, and the possibility that this is linked to the uptake of apoptotic cells is discussed.

Abstract
CD47 is a versatile cell-surface molecule expressed on nearly all haematopoietic cells. In its capacity as a thrombospondin-1 (TSP-1) receptor, CD47 has recently been shown to mediate cell death in certain cells, for example, activated but not resting T cells. Here, we have investigated the possibility that human monocytes and dendritic cells (DCs) undergo cell death, following CD47 ligation. Using the TSP-1-derived CD47-binding peptide 4N1K, we found that both freshly isolated monocytes and monocyte-derived DCs underwent a rapid, caspase-independent cell death. This was characterized by the simultaneous presence of phosphatidylserine exposure, plasma membrane permeability, reduced mitochondrial membrane potential and highly fragmented DNA. Not all cells were sensitive to 4N1K-induced apoptosis; a plateau of cell death reached at an average of 38% of the monocyte and DCs populations. The results presented here, thus, show that CD47 can mediate a rapid apoptosis-like cell death of human monocytes and DCs.

Abstract
A total of 340 patients referred for in-vitro fertilization was included in a retrospective, comparative study in which zygotes were studied regarding alignment and polarization of nucleolar precursor bodies (NPB) and also early cleavage in relation to implantation and pregnancy rates for the 680 transferred embryos. At assessment of the pronucleus 18-19 h after sperm injection, NPB were checked for alignment/polarization. Twenty-six hours after sperm insemination the zygotes were assessed for early cleavage. At embryo transfer the two embryos with the best morphological score, irrespective of polarization and early cleavage, were selected for transfer. The overall rate of positive HCG tests 17 days after embryo transfer was 42% and the implantation rate 23%. Fourteen percent of the patients received two embryos with polarized NPB, with a positive HCG test of 51%. Embryo transfer with early-cleaved embryos was carried out in 21% of the cycles, with a pregnancy rate of 45%. Embryos with polarized NPB and/or early cleavage were transferred in 34% of the cycles, with a pregnancy rate of 51%, compared with a pregnancy rate of 38% when none of the embryos fulfilled these criteria (P-value 0.02). In this study the pregnancy rate was significantly higher when one or two embryos were polarized and/or early cleaved. It is concluded that in a cohort of morphologically good embryos, assessment for alignment/polarization of NPB and/or early cleavage can, together with conventional morphological criteria, serve as a simple non-invasive method for selection of embryos with high implantation potential.

Abstract
Reports concerning the benefit of reducing the co-incubation time of gametes in connection with IVF have been conflicting. The present randomized study was undertaken to determine whether a reduced co-incubation time would improve the embryo development and consequently the pregnancy and implantation rates. Oocytes from 87 patients were collected and half the oocytes from each patient (n = 488, group A) were randomized to 2 h incubation and the other half (n = 504, group B) to overnight incubation. The oocytes were then cultured according to our standard procedure. Significant difference (P = 0.02) was observed between the two groups regarding fertilization rate and polyspermy (group A 72.5%, 3% and group B 80.5%, 6% respectively). However, no difference was observed in further development and morphology of the embryos. The two embryos with the best morphological score were selected for transfer. No significant difference was found between the different transfer groups regarding positive serum HCG and implantation rate. CONCLUSION: The present results and results from previously published studies indicate that the most important factor in connection with the culture method currently used is the amount of sperm added for co-incubation. This should be optimized to reduce the concentration of harmful sperm waste products and create optimal culture conditions.

Abstract
During recent years, the view of the relative importance of the HLA Cw locus has undergone substantial change. From being an HLA locus with both limited polymorphism and biological significance there are now more than a hundred different alleles known and the biological importance of HLA Cw, both as a transplantation antigen and as a receptor for NK cells, is well established. Sequence based typing has been shown to be a powerful tool, especially for HLA Cw typing. Here we describe two new HLA Cw* alleles found during routine typing of potential bone marrow donors and hematological patients. The HLA Cw*0105 differs from Cw*0102 at positions 361 and 368 in exon 3 leading to a Trp to Arg and Cys to Ser substitution, respectively. HLA Cw*1405 differs from Cw*14021 by a single nucleotide substitution at position 368. This mutation results in an amino acid substitution of Phe for Tyr.

Abstract
PURPOSE The aim of this study was to evaluate the value of occupational therapy assessments used in an outreach rehabilitation programme to predict return to work after brain injury. The assessments represent the ICIDH-2 levels of body function and activity. METHOD Fifty-six persons in a late phase after brain injury who had been admitted to the rehabilitation programme during 2 years were followed up according to work status. The follow up was made at a minimum of 2 years after injury. Demographic data and scores from the occupational therapy assessments were compared for the two groups who were back to work or studies (BTW) and not back to work or studies (NBTW). RESULTS Assessments of memory, visual perception and apraxia separated between the two groups BTW and NBTW. Logistic regression showed that memory score in combination with data on PADL made up the best predictive model. In a subgroup with 21 persons where data on IADL were added to memory and PADL the predictive value was even stronger. CONCLUSIONS In this study we found that occupational therapy assessments were valuable in predicting failure to return to work or studies after brain injury.

Abstract
OBJECTIVE To examine the associations between the consumption of fruit and vegetables and other markers of cancer risk. DESIGN A cross-sectional survey within the population-based prospective Malmö Diet and Cancer (MDC) Study. Information on food habits was collected through the modified diet history method designed and validated for the MDC Study. Data on smoking and alcohol habits, leisure time physical activity, birth country, education, socioeconomic status and cohabitation status were collected through a questionnaire. SETTING Malmö, the third largest city in Sweden. SUBJECTS All subjects who entered the MDC Study during winter 1991 to summer 1994 (men and women living in Malmö, aged between 46 and 68 years), with a total of 15 173. RESULTS Women consumed more fruit and vegetables than men. Low consumption of both fruits and vegetables was associated with unfavourable nutrient profiles: higher percentage of energy from fat and lower intakes of antioxidant nutrients and dietary fibre. Low consumption was also associated with smoking, low leisure time physical activity, low education and being born in Sweden. High age was associated with low vegetable consumption in both genders. CONCLUSION This study indicates that several established risk markers and risk factors of cancer may be independently associated with low fruit and vegetable consumption. The findings suggest that the adverse effects of factors such as smoking, low physical activity and a high-fat diet could partly be explained by low consumption of fruit or vegetables. The implied health benefits of a low or moderate alcohol consumption may be similarly confounded by high consumption of fruit or vegetables.

Abstract
Hereditary non-polyposis colorectal cancer (HNPCC) is an autosomal dominant disease, predisposing to the development of colorectal cancer and other tumor types such as endometrial, small bowel, stomach, ovary and urinary tract carcinoma, while most investigators find no association between HNPCC and cancer of the breast. We have identified hMLH1 mutations in 2 Amsterdam-criteria HNPCC families where both male and female gene carriers were affected with breast cancer. To investigate whether these breast cancers were caused by other genetic factors, we analyzed the 2 breast cancer susceptibility genes BRCA1 and BRCA2. In one family we did not find any mutation in the breast cancer genes, while in the other, a BRCA1 mutation segregated in the breast cancer cases. Hereditary breast cancer, and in particular BRCA1 tumors, display discrete histo-pathological and immunohistological characteristics. The tumor from a woman with both hMLH1 mutations and a BRCA1 mutation exhibited typical BRCA1 histology, e.g., grade 3 invasive ductal carcinoma with dense lymphocytic infiltration, and immunohistology, estrogen receptor (ER) negative, progesterone receptor (PgR) negative, strongly p53 positive, c-erbB-2 negative and highly Ki67 positive (>50% stained cells). The histology of the breast tumor from the man with both one hMLH1 mutation and a BRCA1 mutation was a grade 2 invasive ductal carcinoma without any special BRCA1 features. Immunohistology was also different. This might merely reflect a true difference in male breast tumor progression vs. female. We cannot exclude that the combined effect of BRCA1 and hMLH1 dysfunction has a bearing on tumor progression.

Abstract
Apoptosis was induced in human foreskin fibroblasts by the redox-cycling quinone naphthazarin (5,8-dihydroxy-1,4-naphthoquinone). Most of the cells displayed ultrastructure typical of apoptosis after 8 h of exposure to naphthazarin. Apoptosis was inhibited in fibroblasts pretreated with the cathepsin D inhibitor pepstatin A. Immunofluorescence analysis of the intracellular distribution of cathepsin D revealed a distinct granular pattern in control cells, whereas cells treated with naphthazarin for 30 min exhibited more diffuse staining that corresponded to release of the enzyme from lysosomes to the cytosol. After 2 h, release of cytochrome c from mitochondria to the cytosol was indicated by immunofluorescence. The membrane-potential-sensitive probe JC-1 and flow cytometry did not detect a permanent decrease in mitochondrial transmembrane potential (delta psi(m)) until after 5 h of naphthazarin treatment. Our findings show that, during naphthazarin-induced apoptosis, lysosomal destabilization (measured as release of cathepsin D) precedes release of cytochrome c, loss of delta psi(m), and morphologic alterations. Moreover, apoptosis could be inhibited by pretreatment with pepstatin A.

Abstract
The fetal and even the young brain possesses a considerable degree of plasticity. The plasticity and rate of neurogenesis in the adult brain is much less pronounced. The present study was conducted to investigate whether housing conditions affect neurogenesis, learning, and memory in adult rats. Three-month-old rats housed either in isolation or in an enriched environment were injected intraperitoneally with bromodeoxyuridine (BrdU) to detect proliferation among progenitor cells and to follow their fate in the dentate gyrus. The rats were sacrificed either 1 day or 4 weeks after BrdU injections. This experimental paradigm allows for discrimination between proliferative effects and survival effects on the newborn progenitors elicited by different housing conditions. The number of newborn cells in the dentate gyrus was not altered 1 day after BrdU injections. In contrast, the number of surviving progenitors 1 month after BrdU injections was markedly increased in animals housed in an enriched environment. The relative ratio of neurogenesis and gliogenesis was not affected by environmental conditions, as estimated by double-labeling immunofluorescence staining with antibodies against BrdU and either the neuronal marker calbindin D28k or the glial marker GFAp, resulting in a net increase in neurogenesis in animals housed in an enriched environment. Furthermore, we show that adult rats housed in an enriched environment show improved performance in a spatial learning test. The results suggest that environmental cues can enhance neurogenesis in the adult hippocampal region, which is associated with improved spatial memory.

Abstract
The objective was to examine relationships between meat and other food items which have been associated with higher risk of cancer in the colon and prostate in some epidemiological studies. The study was conducted as a population-based cohort study comprising 11648 subjects (4816 male and 6742 female) born between 1926 and 1945 and living in the city of Malmö, Sweden. Data on mean daily intake of foods and nutrients were assessed with a diet history method combining a 7-day menu book and a food frequency questionnaire. Increasing meat intake, expressed in quintiles and adjusted for energy, was associated with decreasing intakes of poultry, fish, fruits, bread, cereals and cheese in both sexes. Low negative correlations between meat intake and ascorbic acid (r= -0.11) and fiber (r= -0.16 to -0.20) were noted. The average intake of fat from meat out of total fat intake was 13.6% in men and 11.9% in women. No major associations were noted between meat and the cholesterol raising fatty acids C:12:0, C:14:0, C:160 nor for C:20:4 or its precursor C:18:2. In conclusion, our findings indicate that meat consumption is negatively associated with food groups rich in antioxidants and fiber and the positive covariance reported between meat and cancer and coronary heart disease might, therefore, not be directly linked to components in meat.

Abstract
BACKGROUND Mercury causes in mouse strains of the H-2s haplotype an autoimmune syndrome with antibodies to the nucleolar protein fibrillarin and systemic immune complex (IC) deposits. Other strains, like BALB/C (H-2d), develop only IC deposits, and most strains are resistant. However, mercury activates the murine immune system and causes lymphoproliferation in most strains: H-2s strains are high-responders also in this respect, while the relation between lymphoproliferation and autoimmune manifestations is unclear for other strains. We examined the B cell response to mercury in order to better understand the relation between lymphoproliferation and systemic autoimmunity, using the high-responder H-2s strains (A.SW and SJL), the intermediate responder strain BALB/C (H-2d), and the A. TL (H-2tl) and DBA/2 (H-2d) strains which are resistant to systemic autoimmunity. METHODS During 4-7 weeks of subcutaneous mercuric chloride injections, the number of B cells and the expression of cell surface activation and proliferation markers was monitored by flow cytometry. The number of cytoplasmic Ig+ splenocytes was determined by direct immunofluorescence technique on slides, and serum Ig isotype levels as well anti-ssDNA and anti-DNP antibodies were determined by ELISA. Serum ANA were monitored weekly by indirect immunofluorescence technique. RESULTS Mercury-treated A.SW and SJL mice (H-2s) developed an increased expression of the proliferation marker CD71 on B cells, an increased number of B cells in the spleen, and an early, strong, but transient increase in serum Ig concentrations of Th1- as well as Th2-regulated Ig isotypes. Mercury-treated H-2s mice rapidly developed a polyclonal B cell response including the IgM isotype, but also antinucleolar antibodies (ANoA) of the IgG isotype with a clumpy pattern, characteristic for antifibrillarin antibodies. The IgG ANoA response was of a long duration and high titer. The A.TL strain (H-2tl) showed only a slight, restricted B cell activation. The BALB/C strain developed a slight, transient B cell activation dominated by IgG1 and IgE, and antinuclear antibodies (ANA). The DBA/2 strain showed only a minimal B cell response without ANA. CONCLUSION Mercury induces an early, transient, polyclonal B cell activation linked to the H-2A or H-2K locus in H-2s strains on the A background. This polyclonal response differs from the long-lasting, high-titered IgG autoantibody response to a nucleolar antigen with characteristics of fibrillarin in H-2s strains, which indicates that these responses arise from separate mechanisms. Another group of strains, exemplified by BALB/C (H-2d), responds to mercury with a slight, transient, Th2-dominated B cell response, a restricted antibody specificity targeting the cell nucleus, and systemic IC deposits. Another H-2d strain, DBA, is essentially resistant to mercury, illustrating the importance of non-H-2 genes for regulating the response to mercury.

Abstract
BACKGROUND The use of adjuvant tamoxifen to treat postmenopausal breast carcinoma patients as an adjunct to primary surgery is well established. The current study reports the long term results for a low risk stratum in a randomized trial of adjuvant tamoxifen. The main focus of this analysis was to determine whether tamoxifen would result in a reduced local failure rate for lymph node negative, postmenopausal patients treated with breast-conserving surgery and postoperative radiotherapy. METHODS The study population included 432 lymph node negative, postmenopausal patients with invasive breast carcinoma (classified as T1-T2) who underwent breast-conserving surgery followed by radiotherapy in Stockholm during the period 1976-1990. The patients constituted a separate stratum of the Stockholm Adjuvant Tamoxifen Trial, which included a total of 2729 patients. Of 432 patients, 213 received 40 mg of tamoxifen daily for either 2 or 5 years. The median follow-up time was 8 years (range, 5-19 years). RESULTS At 10 years, the overall survival was 90% for the tamoxifen group and 88% for the control group. The event free survival at 10 years was 80% for the tamoxifen group and 70% for the control group (P=0.03). Tamoxifen reduced the overall rate of ipsilateral (hazard ratio=0.4, 95% confidence interval [CI]=0.2-0.9, P=0.02) and contralateral breast tumor recurrences (hazard ratio=0.4, 95% CI=0.1-1.1, P=0.06). Trends toward a reduced number of distant metastases (hazard ratio=0.6, 95% CI=0.3-1.2, P=0.1) and deaths due to breast carcinoma (hazard ratio=0.5, 95% CI=0.2-1.2, P=0.1) also were observed. CONCLUSIONS. The addition of tamoxifen to radiotherapy for postmenopausal, lymph node negative breast carcinoma patients treated with breast-conserving surgery resulted in a reduced rate of ipsilateral and contralateral breast tumor recurrences. The avoidance of salvage mastectomies, reexcisions, and new contralateral malignancies justifies the use of tamoxifen even in the treatment of patients with a 10-year survival rate of 90%.
