Abstract
Purpose Hysterectomy has been associated with increased risk for developing stress urinary incontinence (SUI) and having a SUI operation. We examined the long-term rate of SUI operations after hysterectomy and associated risk factors. Methods We followed up 5000 women without prior urinary incontinence (UI) who had a hysterectomy in a prospective FINHYST 2006 cohort study until the end of 2016 through a national health register. The main outcome was SUI operations, and secondary outcomes were outpatient visits for UI, and their association of preoperative patient and operation factors. Results During the median follow-up time of 10.6 years (IQR 10.3–10.8), 111 (2.2%) women had a SUI operation and 241 (4.8%) had an outpatient visit for UI. The SUI operation rate was higher after vaginal hysterectomy and laparoscopic hysterectomy (n = 71 and 28, 3.3% and 1.8%, respectively) compared to abdominal hysterectomy (n = 11, 0.8%). In a multivariate risk analysis by Cox regression, the association with vaginal hysterectomy and SUI operation remained significant when adjusted for vaginal deliveries, preceding pelvic organ prolapse (POP), uterus size, age and BMI (HR 2.4, 95% CI 1.1–5.3). Preceding POP, three or more deliveries and laparoscopic hysterectomy were significantly associated with UI visits but not with SUI operations. Conclusion After hysterectomy, 2.2% of women underwent operative treatment for SUI. The number of SUI operations was more than double after vaginal hysterectomy compared to abdominal hysterectomy, but preceding POP explained this added risk partially. Preceding POP and three or more vaginal deliveries were independently associated with UI visits after hysterectomy.

Abstract
Quantification of regional myocardial blood flow (rMBF) with first-pass magnetic resonance imaging (FP-MRI) requires two contrast agent injections (dual bolus technique), inducing error in the determined rMBF if the injections differ. We hypothesize that using input and residue curves of the same injection would be more reliable. We aim to introduce and evaluate a novel method to correct the high concentration arterial input function (AIF) for determination of rMBF. Sixteen patients with non-Hodgkin's lymphoma were examined before and after chemotherapy. The input function was solved by correcting initial high concentration AIF using the ratio of low and high contrast AIF areas, normalized by corresponding heart rates (modified dual bolus method). For comparison, the scaled low contrast AIF was used as an input function (dual bolus method). Unidirectional transfer coefficient K(trans) was calculated using both methods. K(trans)-values determined with the dual bolus (0.81 ± 0.32 ml g(-1) min(-1)) and modified dual bolus (0.77 ± 0.42 ml g(-1) min(-1)) methods were in agreement (p = 0.21). Mean K(trans)-values increased from 0.76 ± 0.43 to 0.89 ± 0.55 ml g(-1) min(-1) after chemotherapy (p = 0.17). The modified dual bolus technique agrees with the dual bolus technique (R2 = 0.899) when the low and high contrast injections are similar. However, when this is not the case, the modified dual bolus technique may be more reliable.

Abstract
Mobilization and collection of stem cells is difficult in a proportion of patients intended for autologous stem cell transplantation (ASCT). We have evaluated mobilization kinetics of blood CD34(+) cells (B-CD34(+)) to form basis for algorithm to facilitate rational pre-emptive plerixafor use. Altogether 390 chemomobilized patients were included.Forty-three patients (11%) did not reach BCD34+count ≥10×10(6)/l. Mobilization kinetics differed according to the mobilization capacity observed. Among those who were very poor or inadequate mobilizers (peak BCD34(+)count ≤5×10(6)/l and 6–10×10(6)/l, respectively), BCD34+counts rarely rose after white blood cells (WBC) >5–10×10(9)/l, whereas in many standard mobilizers a later rise in CD34(+) counts could be observed. Four algorithms based on WBC and CD34(+) counts were constructed. According to this patient series, algorithm II (WBC >5×109/l and BCD34+≤10×10(6)/l) and algorithm IV (WBC >10×10(9)/l andB-CD34(+) ≤10×10(9)/l) were the most applicable. For algorithm II the sensitivity was 0.97 and specificity 1.00, respectively, to identify patients for plerixafor use provided that all patients with B-CD34+ maximum ≤10×10(6)/l would have needed plerixafor.This simple model needs a prospective validation.

Abstract
OBJECTIVES Limited data are available on the cardiac effects of high-dose cyclophosphamide (CY) in patients with non-Hodgkin's lymphoma (NHL). We prospectively assessed the cardiac effects of high-dose CY in 30 adult NHL patients receiving CY 6 g/m(2) as part of BEAC high-dose therapy (HDT). METHODS Radionuclide ventriculography (RVG) and plasma natriuretic peptide (NT-proANP, NT-proBNP) measurements were performed simultaneously prior to BEAC at baseline (d - 7), 12 days (d + 12) and 3 months (m + 3) after stem cell infusion (D0). In addition to these time points, natriuretic peptides were measured 2 days before (d - 2) and 1 week (d + 7) after stem cell infusion. RESULTS Left ventricular ejection fraction (LVEF) decreased from d - 7 (53% +/- 2%) to d + 12 (49% +/- 2%, P = 0.009). However, no significant change in cardiac diastolic function was observed. The LVEF returned towards baseline by m + 3. Plasma NT-proANP and NT-proBNP increased significantly from baseline (445 +/- 65 pmol/L and 129 +/- 33 pmol/L) to d - 2 (1,127 +/- 142 pmol/L, P < 0.001 and 624 +/- 148 pmol/L, P < 0.001, respectively). Thereafter, they started to decrease, but on d + 7 NT-proANP (404 +/- 157 pmol/L, P = 0.048) and NT-proBNP (648 +/- 125 pmol/L, P = 0.015) were still significantly higher than at baseline. On d + 12 and m + 3 they no longer differed from baseline. CONCLUSIONS Our findings suggest that high-dose CY results in acute, subclinical systolic dysfunction in NHL patients previously treated with anthracyclines. Natriuretic peptides seem to be more sensitive than LVEF to reflect this transient cardiac effect. Serial measurements of natriuretic peptides might be a useful tool to assess cardiac effects of high-dose CY.

Abstract
Limited information is available on the feasibility and efficacy of autologous stem cell transplantation (ASCT) in multiple myeloma (MM) patients >65 years of age. In 1995-2005, 22 myeloma patients >or=65 years (median 68, eight >or=70) and 79 patients <65 years (median 57) were included in an identical treatment protocol. The first progenitor cell mobilization with cyclophosphamide plus granulocyte-colony stimulating factor (G-CSF) was successful in 95 and 96% of the patients, respectively. To date, 92 patients have received MEL (melphalan) 200 mg/m2 supported by ASCT. No early treatment-related deaths were observed among 22 elderly patients, whereas one younger patient died early. Engraftment and the need for supportive care were comparable between groups. The elderly patients tended to have more WHO grade 3-4 oral or gastrointestinal toxicity when compared to the younger patients (45 vs 23%, P=0.06). After ASCT, a complete response was observed in 44% of the elderly patients and 36% of the younger patients, respectively. No difference was observed between these age groups in progression-free survival (23 vs 21 months) or overall survival (57 vs 66 months) after ASCT. We conclude that MEL200 is a safe and efficacious treatment in selected elderly myeloma patients.

Abstract
Cardiotoxicity is potentially the most threatening nonhaematological side effect of high-dose CY. We prospectively evaluated the very acute cardiac effects of high-dose CY in 17 adult non-Hodgkin's lymphoma (NHL) patients receiving CY 1500 mg/m2/day as a part of BEAC high-dose therapy (HDT). Magnetic resonance imaging (MRI) and plasma natriuretic peptide (NT-proBNP, NT-proANP) measurements were performed prior to HDT (d-7) and just after completing HDT (d-2). After the high-dose CY left atrial end-systolic area increased from 15.2+/-1.2 to 18.5+/-1.4 cm2 (P=0.001), left ventricular end-diastolic volume from 136.1+/-12.3 to 156.6+/-11.1 cm3 (P=0.04) and left ventricular end-systolic volume from 67.4+/-7.8 to 75.3+/-7.1 cm3 (P=0.018). However, no significant change in left ventricular ejection fraction (LVEF) was observed. At the same time, plasma levels of NT-proBNP increased from 134.9+/-53.3 to 547.1+/-168.4 pmol/l (P=0.003) and NT-proANP from 481.1+/-105.5 to 1056.6+/-193.1 pmol/l (P=0.001), respectively. To conclude, high-dose CY results in very acute cardiac toxicity characterised by enlargement of the heart chambers in NHL patients previously treated with anthracyclines. This toxicity can be detected with increased concentrations of circulating natriuretic peptides but not with LVEF measurement.

Abstract
OBJECTIVES To analyse outcome and prognostic factors in non-Hodgkin's lymphoma (NHL) patients who progress after autologous stem cell transplantation (ASCT). PATIENTS Altogether 115 consecutive NHL patients transplanted in 1991-2000 were studied. Histology included diffuse large B cell (n = 52), follicular (n = 26), mantle cell (n = 15), T cell (n = 16) and other subtypes (n = 6). The median time from ASCT to the progression was 7 months. Ninety-six patients (83%) received salvage treatment. RESULTS Twenty-four patients (25%) achieved complete remission and 30 (31%) partial remission. The median overall survival was 8 months (range 0-98+) and the projected 4-year survival 21%. In multivariate analysis factors predicting treatment response after the progression included the use of rituximab (P = 0.036), histology other than diffuse large B cell (P = 0.001) and International Prognostic Index < or =2 at progression (P < 0.001). Normal lactate dehydrogenase (LDH) at progression (P = 0.002), response to salvage treatment (P < 0.001) and time from ASCT to progression > or =7 months (P = 0.022) were predictors for overall survival. CONCLUSIONS Although the prognosis of patients who progress after ASCT is generally poor, many patients will respond to current therapies, and some may experience prolonged survival. Normal LDH at time of disease progression and longer time to progression after ASCT were the most powerful predictors for a promising outcome.

Abstract
Factors affecting progenitor cell mobilisation in patients with non-Hodgkin's lymphoma (NHL) are incompletely understood. We have analysed factors predicting mobilisation failure in 97 consecutive patients with NHL (59 males, 38 females; median age 49 years) who received mobilisation with intermediate-dose CY (4 g/m(2)) followed by G-CSF. The histology included large cell B (N=50), mantle cell (N=16), follicular (N=16) and other NHL (N=15). The disease status was 1CR/PR/primary refractory in 66 patients and >1 CR/PR in 31 patients. The minimum criterion for successful mobilisation was the collection of >or=1.5 x 10(6)/kg CD34(+) cells. In all, 18 patients (19%) failed to reach this threshold. In univariate analysis, premobilisation factors associated with mobilisation failure included BM involvement at the time of diagnosis (P=0.001) or prior to mobilisation (P=0.001) and low platelet count just prior to mobilisation (P=0.001). In multivariate analysis, only BM involvement at diagnosis (P=0.004) and platelet count just prior to mobilisation (P=0.01) were associated with mobilisation failure. A mathematical model based on these two factors and presented in the form of a receiver operating characteristics curve showed a sensitivity of 0.71 and a specificity of 0.77 in the prediction of mobilisation failure. Patients at a high risk of mobilisation failure may benefit from novel approaches.

Abstract
About 10-30% of patients with non-Hodgkin's lymphoma (NHL) intended to receive high-dose therapy are difficult to mobilise. Damage to the stem cell pool caused by previous chemotherapy may be an important factor in predicting progenitor cell mobilisation. We have analysed associations between chemotherapy score and efficiency of progenitor cell mobilisation in 120 consecutive NHL patients mobilised with intermediate-dose cyclophosphamide (4 g/m(2)) plus G-CSF. The original chemotherapy scoring system proposed by Drake et al was applicable in only 27% of our patients and was not predictive for mobilisation outcome. Therefore we made an improved scoring system for previous chemotherapy by adding new drugs. Altogether, 111 patients (93%) could be scored. Our chemotherapy score showed an inverse correlation with the peak blood CD34(+) count measured after the mobilisation (r=-0.214, P=0.024) and with the number of CD34(+) cells collected (r=-0.234, P=0.02). However, in the receiver operating characteristics curve, no threshold value could be detected for chemotherapy score predicting mobilisation failure. Thus, both the original scoring system as well as our more widely applicable scoring system seem to be of limited value in predicting progenitor cell mobilisation in patients with NHL.

Abstract
High-dose chemotherapy supported by autologous stem cell transplantation is widely used in patients with non-Hodgkin's lymphoma (NHL). Limited data is available on the comparative toxicity and efficacy of various high-dose regimens applied in NHL. We therefore analysed regimen-related toxicity and outcome in 71 consecutive NHL patients who received either BEAC (N = 36) or BEAM (N = 35) supported by peripheral blood progenitor cell infusion plus granulocyte colony-stimulating factor. The patients who received BEAM had significantly more often WHO grade > 2 mucositis (63 vs. 28%, P = 0.009) and diarrhoea grade >2 (29 vs. 8%, P = 0.062). Septicaemia also tended to be more frequent and the peak CRP value was higher in the BEAM group (140 vs. 113 mg/l, P = 0.034). Transplant-related mortality (< 100 d) was 3 and 9% in the BEAC and BEAM groups, respectively. No significant differences were observed in overall survival or progression free survival between these two groups. While BEAC and BEAM appears to have equal antitumour efficacy in patients with NHL, BEAM seems to be more toxic to the gastrointestinal tract. However, randomised studies are needed for more definitive conclusions on the relative merits of various high-dose regimens in patients with NHL.

Abstract
To evaluate feasibility and potential efficacy of amifostine (AMI) in the prevention of toxicities associated with high-dose melphalan (MEL), ten myeloma patients received AMI 910 mg/m2 in 15 min infusion preceding MEL 200 mg/m2 followed by stem cell infusion (AMI group). Hematologic and extra-hematologic toxicities as well as the need for supportive care observed in the AMI group were compared with ten myeloma patients treated in an identical protocol but without AMI. Hypotension was the most important adverse event of AMI infusion. No differences were observed in the time of engraftment between the AMI group and the control group neither was there any difference in the need for supportive care. Oral mucositis grade >2 was observed in 30% of the patients in both groups. Diarrhea grade >2 occurred only in two AMI patients but in five control patients. AMI preceding high-dose MEL is feasible, although adverse events are observed in some patients. Whether AMI could reduce the gastrointestinal toxicity associated with high-dose MEL can be reliably assessed only in prospective randomized trials.

Abstract
Synpolydactyly (SPD) is a rare malformation of the distal limbs known to be caused by mutations in HOXD13. We have previously described a complex form of SPD associated with synostoses in three members of a Belgian family, which co-segregates with a t(12;22)(p11.2;q13.3) chromosomal translocation. The chromosome 12 breakpoint of this translocation maps to 12p11.2 between markers D12S1034 and D12S1596. Here we show that a mutation in the HOXD13 gene is not responsible for the phenotype, and present a physical map of the region around the 12p11.2 breakpoint. Starting from D12S1034 and D12S1596, we have established a contig approximately 1.5 Mb in length, containing 13 YAC clones, 16 BAC clones, and 11 cosmid clones. FISH analysis shows that cosmid LL12NCO1-149H4 maps across the breakpoint, and Southern blot experiments using fragments of this cosmid as probes identify a rearranged BamHI fragment in the patients carrying the translocation. A search for expressed sequences within the contig have so far revealed one CpG island, seven anonymous ESTs and three previously characterised genes, DAD-R, KRAG and HT21, all of which were found not to be directly disrupted by the translocation. The gene represented by EST R72964 was found to be disrupted by the translocation. These findings lay the groundwork for further efforts to characterise a gene critical for normal distal limb development that is perturbed by this translocation.

Abstract
A cDNA of a processed gene of human DAD-1 (defender against apoptotic cell death) was cloned from the human neuroblastoma cell line SH-SY5Y. The genomic sequence of this novel processed gene, DAD-R, lacked introns and was flanked by 8 bp terminal repeats. RT-PCR showed that the transcript is expressed predominantly in testis, ovaries, pancreas, lung and skeletal muscle. DAD-R has several possible initiation codons, one of them producing an open reading frame comprising 75% of the DAD-1 gene. We determined the chromosomal localization of DAD-R as 12p11.2-12p12.1, an area linked to familial synpolydactyly and frequently amplified in a variety of cancers, including those of testis, ovaries, pancreas and lungs.

Abstract
Dysfunction and downregulation of dad (defending against death) has been linked to programmed cell death (PCD) in animals and plants. As DAD is an essential subunit of the oligosaccharyltransferase that is located in the ER membrane, the results have raised the possibility that downregulation of N-linked glycosylation could be involved in the regulation of PCD. Here we show that the 16 kDa subunit of phytepsin, a vacuolar proteinase, is normally processed and glycosylated at the onset of DNA fragmentation in germinating barley scutella. Two cDNA clones encoding dad (dad1, dad2), and one cDNA encoding another subunit of the same oligosaccharyltransferase complex (ost1) were isolated from barley. Northern analysis of germinating scutella show that the expression of only dad1 is declining before onset of DNA fragmentation. In contrast to this, the expression of both dad2 and ost1 increase before onset of DNA fragmentation.

Abstract
In this report we describe a type D virus isolated from a human neuroblastoma cell line (Paju). The viral RNA was isolated, partially molecularly cloned and sequenced. Our clones were shown to be identical to a human D-type retrovirus previously isolated from a human lymphoblastoid cell line. However, we obtained no evidence for the virus in earlier passage of the Paju cell line and therefore we must consider this isolate a laboratory contamination. contamination.

Abstract
Antacids are drugs of choice in the treatment of reflux esophagitis and peptic ulcer disease, where acid regurgitation may cause dental erosion. Since there are no specific preventive measures or effective treatment for erosions, the present study was made to assess whether the keeping of antacids in the mouth before swallowing would be beneficial with regard to their effect on mouth pH, after acidic challenge. Five healthy subjects formed the test panel. After measuring the acid binding capacity of all the antacid preparations in the Finnish market, the two most effective were selected for testing, one in emulsion form (Novaluzid), the other a tablet (Link). Acid regurgitation was mimicked by consuming a low-pH (3.2) drink immediately before the antacid. Control series were made with the acidic drink only. Both the antacids were found to counteract totally the pH fall caused by the drink, when measured as changes in the tongue surface pH. The Novaluzid preparation was more effective than the Link preparation but the difference was not significant. It may be anticipated that patients suffering from acid regurgitations would benefit if they are counseled to keep their antacids in the mouth for a while before swallowing.
