RESUMEN

PURPOSE: Medication-related problems and declined functional capacity are closely associated factors among older people. The purpose of this study is to describe the procedure of interprofessional medication assessment in home care context and the baseline characteristics of the study population. METHODS: The FIMA study was a randomized, controlled intervention study comparing general practitioner-led interprofessional medication assessment and usual care. Patients' chronic diagnoses and medication use as well as physical and cognitive functions were investigated. Performance in daily activities, use of care services and help from family and relatives, self-rated health and health-related quality of life, and adverse effects commonly related to medication were assessed. RESULTS: The home care patients (n = 512) had significant disease burden and functional limitations. The mean number of all medicines was 15 and that of regularly taken medicines 10. The majority of patients (87%) had excessive polypharmacy. The most commonly used (97%) ATC medicine class was nervous system medicines. Clinically relevant (class C or D SFINX record) drug-drug interactions were seen in 74% of the patients. The most frequent risks of adverse effects were risk of bleeding (66%), constipation (58%) and orthostatism (54%) occurring in over half of the patients. Medicines affecting renal function were used by 85% of the patients. CONCLUSIONS: There is an evident need and justification for medication assessments in home care. In most cases, home care patients fulfill the criteria for regular medication assessments.

RESUMEN

PURPOSE: Testicular ischemia and necrosis are uncommon complications after inguinal hernioplasty. Our aim was to evaluate the incidence of severe urological complications related to adult inguinal hernia surgery in Finland with special reference to orchiectomy in relieving intractable chronic testicular pain. METHODS: All urological complications related to inguinal hernia surgery during 2003-2010 were analysed from the Finnish Patient Insurance Centre. The patients with intractable chronic scrotal or testicular pain that resulted in orchiectomy were re-evaluated after a median follow-up of 7 years (range 2-15 years). The operative factors related to chronic testicular pain and atrophy were analysed using multiple regression analysis. RESULTS: Altogether 62 urological complications (from 335 litigations) were recorded from 92,000 inguinal hernia operations. The distribution of claimed urological complications consisted of 34 testicular injuries, ten bladder perforations, seven massive scrotal haemorrhage or 11 miscellaneous injuries. Seventeen atrophic testes were left in situ and 17 (six early < 7 days, 11 late > 8 days) orchiectomies were performed due to necrosis or chronic testicular pain syndrome. In the conservative group of moderate scrotal or testicular pain (n = 17), all patients had late pain symptoms (>8 days), but pain was not so severe that orchiectomy was attempted. Using a multivariate analysis, postoperative infections were associated with chronic testicular or scrotal pain and atrophy, but hospital status, surgeon's training level, laparoscopic or open operation, type of hernia or use of mesh did not correlate with testicular injuries. During follow-up, 11/17 (65%) patients with orchiectomy were free of testicular pain. CONCLUSION: Urological injuries form one-fifth of the major complications after inguinal hernioplasty. Orchiectomy appears to help the majority of patients with severe testicular pain syndrome.

RESUMEN

BACKGROUND: Anxiety frequently accompanies low-grade inflammation-associated conditions like depression, insulin resistance, coronary heart disease and metabolic syndrome. The association between anxiety and low-grade inflammation is, unlike between depression and low-grade inflammation, a very sparsely studied area in general populations. The aim of the present study was to investigate whether anxiety symptoms as well as comorbid anxiety and depressive symptoms are associated with low-grade inflammation at population level. METHODS: The general population-based Northern Finland 1966 Birth Cohort was followed until age 31 (n=2688 males and 2837 females), when the highly sensitive CRP concentrations were measured. Anxiety and depressive symptoms were defined by Hopkins Symptom Checklist-25 (HSCL-25). RESULTS: After adjusting for confounders, logistic regression analyses showed that anxiety symptoms alone increased the probability for elevated hs-CRP levels (>3.0mg/L) in males over two-fold (2.19 CI 95% 1.08-4.46), while comorbid anxiety and depressive symptoms caused a 1.7-fold (1.76 CI 95% 1.13-2.74) increase in the probability for elevated hs-CRP levels (1.0-3.0mg/L). CONCLUSIONS: Our results support the hypothesis that anxiety as well as comorbid anxiety and depression can be associated with an increased risk for low-grade inflammation in males at population level.

RESUMEN

Sex-biased dispersal is often connected to the mating behaviour of the species. Even if patterns of natal dispersal are reasonably well documented for monogamous birds, only a few data are available for polygynous and especially lekking species. We investigated the dispersal of the capercaillie (Tetrao urogallus) by examining sex-specific gene flow among the leks. Genetic information was extracted using nuclear and mitochondrial molecular markers for sexed faecal samples and analysed by novel Bayesian statistical methods. Contrary to the traditional view that the males are highly philopatric and female is the dispersing sex, we found roughly equivalent gross and effective dispersal of the sexes. The level of polygamy has a strong influence on the effective population size and on the effective dispersal. The results do not support the theories that dispersal evolves solely as a result of resource competition or other advantages to males obtained through kin selection in lekking species.

RESUMEN

As part of an International Agency for Research on Cancer (IARC) international epidemiological study of workers in the pulp and paper industry, previously unpublished exposure measurements were assembled in a database. This article summarizes the results of 3,873 measurements carried out in the production departments of paper and paperboard mills and recycling plants in 12 countries. In the paper and paperboard mills, most of the agents were measured in the pulping and refining departments and in on-machine coating and winding of paper/paperboard. Exposures to asbestos, carbon monoxide, formaldehyde, fungal spores, bacteria, nitrogen dioxide, minerals dusts, paper dust, sulphuric acid and different solvents sometimes exceeded exposure limit values. In the re-pulping and de-inking departments of recycling plants high exposures to formaldehyde, fungal spores, bacteria and paper dust were observed. High exposures to asbestos, bioaerosols, carbon monoxide and paper dust were found in many departments; ammonia, formaldehyde, mineral and paper dust and solvents were found in coating machines; and diphenyl and polychlorobiphenyls (PCBs) were found in some special circumstances. Measurements in the newsprint and uncoated paper machine departments revealed only a few elevated exposures. In nearly all departments, measurements of epichlorohydrin, PCBs, sulphur dioxide, hydrogen sulphide and mercaptans tended to be low, often even below their detection limits. In spite of some uncertainties in the measurement data, the study provides new insights into the level and variation of occupational exposures of production workers in the paper and paperboard industry.

RESUMEN

OBJECTIVES: Urine cytology is the gold standard in the diagnosis and follow-up of bladder cancer. Cytology, however, exhibits variable sensitivity depending on tumour grade and interpretation of urine specimens is highly dependent on the skill of the examiner. Positive cytology, classes IV and V by Papanicolaou classification, is a strong predictor for coexisting or subsequent malignancy, while the role of suspicious cytology, class III, is controversial. The objective of the study was to evaluate the role of the suspicious finding in cytological analysis, and whether it should be considered as a negative or positive sign for coexisting malignancy. MATERIAL AND METHODS: Six hundred and fifty-two consecutive patients with bladder cancer were studied in a prospective multicenter trial. One hundred and fifty-one of the patients were newly diagnosed, and the remaining 501 patients were under follow-up. A voided urine sample was obtained prior to TURB or prior to routine follow-up cystoscopy in those under the surveillance and split for culture and cytology. The cytopathological results were analyzed by a central review and only patients with samples available for review analysis were included. Sensitivity and specificity, as well as positive (PPV) and negative (NPV) predictive values of urine cytology were calculated by classifying the class III samples as negative or positive. RESULTS: A total of 570 patients were evaluable. One hundred and twenty nine (22.6%) were newly diagnosed and 441 were under follow-up, of whom 117 (26.5%) had recurrence. Cytology was classified as suspicious in 33/129 (25.6%) patients with primary tumour, and in 41/441 (9.3%) of those under the follow-up, of whom 20 (48.8%) had recurrence. Sensitivity increased from to 31.0% to 56.6% in primary tumours (p < 0.001) and from 17.8% to 34.7% in recurrent tumours (p < 0.001) if class III was determined as positive, whereas the specificity decreased from 96.6% to 90.1% (p < 0.001). Accordingly, the NPV increased from 76.3% to 79.1% and the PPV decreased from 65.6% to 56.2%. CONCLUSIONS: The poor sensitivity of voided urine cytology improved significantly when suspicious samples were determined as positive while the specificity remained high, a clear advantage compared with most of the new tumour marker tests. In addition, nearly half of the follow-up patients with suspicious class III cytology had recurrence implying that this patient category is at substantial risk for co-existing malignancy. Therefore, it is recommended that suspicious class III cytology together with class IV and V specimens should be considered positive.

RESUMEN

This article describes an experimental study of terpene emission rates during fresh pine and spruce sawing and processing. Total terpene emission was determined by summing the product of the exhaust airflow rate and the mean concentration in the exhaust. Terpene concentrations were measured at fixed sampling points between the sawing lines. Terpene emission during pine sawing was found to be around 10 times greater than that during spruce sawing. The emission rates given here can be used to predict emission rates for various production rates. The predicted emission rates can be used in mass balance models to predict concentrations or required airflow rates to achieve the target concentration level.

RESUMEN

OBJECTIVES: To evaluate the role of a positive BTA stat Test result in patients with negative cystoscopic findings. METHODS: Five hundred one consecutive patients in follow-up for bladder cancer were studied. A voided urine sample was obtained before cystoscopy and split for culture, cytology, and BTA stat testing. In the case of a positive BTA stat Test, but negative cystoscopic findings, patients underwent additional investigations. RESULTS: Of 501 patients, 133 (26.5%) had bladder cancer recurrence at cystoscopy, of which the BTA stat Test detected 71 (53.4%); only 21 of the cases (17.9%) were detected by cytologic examination. Of the remaining 368 patients with no visible tumor at cystoscopy, 96 (26.1%) had a positive BTA stat Test result. Fifty-five of those (57.3%) underwent intravenous urography or renal ultrasound and random biopsies, and an additional 9 recurrences (16.4%) were detected. Of those 46 patients who had a true false-positive BTA stat Test, 3 (3 of 43, 7.0%) had recurrence at the next follow-up cystoscopy, 4 (8.7%) had a urine infection, and 8 (17.4%) had ongoing intravesical instillations; the latter two percentages were significantly higher than among those with true-negative BTA stat Test results (0% and 6.8%, respectively). CONCLUSIONS: Patients with a positive BTA stat Test result but negative cystoscopic findings have about a 16% risk of an undetected recurrence. False-positive results may be due to present instillation treatment and urine infection, and the predictive value of a BTA stat Test for subsequent recurrence seems relatively low.

RESUMEN

BACKGROUND AND AIMS: Urine cytology is gold standard for clinical tests used in the diagnosis and follow-up of bladder cancer. Cytology, however, exhibits variable sensitivity depending on tumour grade and interpretation of urine specimens is highly dependent on the skill of the examiner. Furthermore, a "suspicious" cytology report (class III) makes clinicians uncomfortable. In these cases, a more objective test, such as the BTA stat Test, may be useful in providing clarification. The aim of this study was to evaluate the dilemma of suspicious routine urine cytology and to determine whether the BTA stat Test provides diagnostic aid in this rare but controversial category. MATERIAL AND METHODS: 506 consecutive patients who were being followed for bladder cancer were included in the study. A voided urine sample was obtained prior to routine follow-up cystoscopy and split for culture and testing with the BTA stat Test. Clinical status of the disease was evaluated in patients with suspicious urine cytology, and the diagnostic aid of the BTA stat Test in these patients was determined. RESULTS: A total of 57 patients (11.3%) had urine cytology classified as suspicious. The BTA stat Test was positive in 29 (50.9%) and negative in 28 (49.1%) patients. Nineteen (33.3%) patients had recurrence at routine cystoscopy. Of the remaining 38 patients, 10 were further investigated due to a positive BTA stat Test. Two additional recurrences were detected bringing the total number of recurrences to 21 (36.8%), 48.3% (14/29) of the patients with positive and 25.0% (7/28) of the patients with negative BTA stat Test had recurrence (p = 0.069). Overall, 65.5% (19/29) of the patients with a positive BTA stat Test were found to have recurrence either at routine cystoscopy, at further investigations, or at the next cystoscopy compared to that of 35.7% (19/28) in those with negative testing (p = 0.024). The overall sensitivity of the BTA stat Test was 66.7%, and the specificity was 58.3%. CONCLUSIONS: At least a third of the patients under follow-up for bladder cancer with suspicious cytology had a recurrence, indicating that these patients are a risk group for recurrence. More importantly, a BTA stat Test result seems to provide some help in distinguishing those patients with very high risk for recurrence, for whom invasive further investigations should be conducted and a close follow-up policy maintained.

RESUMEN

Immunoreactivity of p21WAF1/CIP1 and cyclin D1 proteins was assessed in a cohort of 207 patients with superficial (pTa-pT1) bladder cancer followed up for a mean of 4.9 years. The results of the immunostainings were compared with T category, WHO grade, tumor cell proliferation rate (MIB-1 score), the expressions of p53 and bcl-2 as well as survival. Sixty-eight percent and 75% of the tumors were p21WAF1/CIP1 positive (> or = 5% of cells positive) and cyclin D1 positive (> or = 10% of cells positive), respectively. The p21WAF1/CIP1 expression was related to cyclin D1 immunolabelling (P < 0.001) but not to the other variables studied. The expression of cyclin D1 was inversely associated with T category (P = 0.001), WHO grade (P = 0.006), MIB-1 score (P = 0.014), p53 expression (P = 0.001), and bcl-2 (P = 0.011) immunoreactivity. In univariate analysis, T category (P = 0.0001), WHO grade (P < 0.0001), MIB-1 score (P < 0.0001), bcl-2 (P = 0.0092), p53 (P = 0.0016) and p21WAF1/CIP1 (P = 0.009) expressions were significant prognostic factors with regard to tumor progression, whereas cyclin D1 was without any prognostic significance (P = 0.1). Out of 123 p21 positive tumors 21 progressed, whereas only 2 out of 58 p21 negative tumors progressed. In multivariate analysis, the MIB-1 score was the only independent predictor of cancer-specific survival (P = 0.03), whereas tumor grade (P = 0.002) and cyclin D1 expression (P = 0.04) were independent predictors of tumor recurrence. Only the WHO grade (P = 0.04) retained its prognostic value indicating the risk of progression. We suggest that in superficial bladder cancer p21WAF1/CIP1 and cyclin D1 immunohistochemistry provide no additional prognostic information compared with already established prognostic factors for predicting the risk of progressive disease.

RESUMEN

PURPOSE: We evaluated alternatives to bacillus Calmette-Guerin (BCG) monotherapy using a new combination of chemotherapy and immunotherapy for recurrent superficial bladder carcinoma. MATERIALS AND METHODS: A total of 236 patients with frequently recurrent stage Ta or T1 bladder tumors were enrolled in our prospective, randomized, multicenter Finnbladder IV study. The initial mitomycin C instillation was instilled in all patients perioperatively after transurethral resection, followed by 4 weekly instillations of mitomycin C. Thereafter patients were randomized to receive monthly for up to 1 year BCG only or interferon-alpha2b and BCG alternating monthly. Primary end points were time to initial recurrence, recurrence rate (number of recurrences per patient-year) and recurrence index (number of recurrent tumors per patient-year). RESULTS: Of the 236 randomized patients 205 were eligible for study with a median overall followup of 30.7 months. Monthly BCG was superior to alternating monthly interferon-alpha and/or BCG with respect to time to initial recurrence (log rank test p <0.00001) as well as recurrence rate (0.4 versus 0.9, p <0.00001) and index (0.9 versus 3.0, p <0.00001). Side effects were limited. CONCLUSIONS: Monthly BCG given for up to 1 year preceded by perioperative and an additional 4 weekly mitomycin C instillations is a well tolerated mode of instillation therapy, providing excellent tumor control comparable to that of the best reported instillation regimens. No benefit was obtained by alternating interferon-alpha2b with BCG.

RESUMEN

OBJECTIVE: A prospective randomized study was undertaken to determine whether cell proliferation indices (M/V index, MIB1), papillary status, the expression of p53 and epidermal growth factor receptor (EGFr) have prognostic value in superficial (pTa-pT1) bladder cancer (SBC). METHODS: 207 patients with primary SBC were followed up over a period of 4.9 (range 3.7-6.0) years. M/V index and papillary status were assessed by light microscopy, and expression of MIB1, p53 and EGFr was assessed by immunohistochemistry. The results of histopathological analyses were related to the survival data of the patients. RESULTS: Using univariate analysis, stage (p < 0.001), grade (p < 0.001), papillary status (p < 0.001), MIB1 (p < 0.001), M/V index (p < 0.001), EGFr (p < 0.001) and p53 (p = 0.002) were significant predictors of progression. Using multivariate analysis, MIB-1 score and papillary status were independent predictors of progressive disease and cancer-specific survival. Tumor grade was the only independent predictor of recurrence. CONCLUSION: Evaluation of tumor cell proliferation rate by M/V index or by MIB1 immunohistochemistry and assessment of papillary status by light microscopy are useful prognostic tools in tailoring treatment and follow-up schedule of patients with SBC.

RESUMEN

BACKGROUND: The aim of the study was to investigate whether exposure to formaldehyde, organic solvents or other chemicals in the wood-processing industry affects the fertility of women. METHODS: For this purpose, a retrospective study on time to pregnancy was conducted among female wood workers who had given birth during 1985-1995. Data on pregnancy history, time to pregnancy, occupational exposures, and potential confounders were collected by a questionnaire; 64% (699/1,094) participated. The exposure assessment was conducted by an occupational hygienist. The data on time to pregnancy were analyzed with the discrete proportional hazards regression. RESULTS: Exposure to formaldehyde was significantly associated with delayed conception: adjusted fecundability density ratio, FDR, was 0.64 (95% CI 0.43-0.92). At high exposure if no gloves were used, the FDR was 0.51 (% CI 0.28-0.92). Exposure to phenols, dusts, wood dusts, or organic solvents was not related to the time to pregnancy. Additionally, an association was observed between exposure to formaldehyde and an increased risk of spontaneous abortion (concerning previous spontaneous abortions, reported by the women). Associations between exposure to formaldehyde or to organic solvents and endometriosis, and between exposure to organic solvents or to dusts and salpingo-oophoritis were also suggested. CONCLUSIONS: The study suggests that a woman's occupational exposure to formaldehyde has an adverse effect on fertility.

RESUMEN

PURPOSE: We evaluated the efficacy of single dose of interferon or epirubicin administered immediately after transurethral resection compared with transurethral resection only on the recurrence of primary (not recurrent) superficial bladder cancer. MATERIALS AND METHODS: A total of 283 patients with stages Ta to T1 primary superficial, grades 1 to 3 bladder cancer was randomized into study groups 1-transurethral resection only, 2-transurethral resection plus 50 million units interferon-a2b and 3-transurethral resection plus 100 mg. epirubicin. Eligible for final analysis were 200 patients, including 66 in group 1, 66 in group 2 and 68 in group 3. Patients were followed with cystoscopy every 3 months for 2 years or until the initial recurrence. RESULTS: Group 3 had the most favorable outcome, since 45 of the 68 patients (66%) were without recurrence after 2 years compared to 24 of the 66 (37%) in group 2 and 26 of the 66 (40%) in group 1 (log rank test p <0.001). Side effects were mostly mild and transient, and no differences were found among the groups. CONCLUSIONS: A single 100 mg. dose of epirubicin given intravesically immediately after transurethral resection is safe, and significantly decreases the recurrence of primary superficial bladder cancer. A 50 million unit dose of interferon-alpha2b is well tolerated but it has no effect on recurrence as a single dose. The long-term effect of this treatment remains to be studied.

RESUMEN

Immunoreactivity of bcl-2, p53, the epidermal growth factor (EGFr) and Ki-67 (MIB-1) proteins was assessed by immunohistochemistry in 185 patients with superficial bladder cancer (SBC) in order to evaluate their usefulness as indicators of tumor progression. Forty-one percent of the tumors were bcl-2 positive, 36% of them were positive for p53 (over 20% of nuclei), while 41% were positive for EGFr, and 30% of the tumors were MIB-1 positive (proliferation index > 15%). Immunoreactivity of all analyzed proteins was highly significantly related to tumor grade and stage. Tumors which were bcl-2, p53 or EGFr positive were also rapidly proliferative (MIB-1 score >15%). The obtained results suggest that all analyzed proteins may have prognostic significance in SBC. The prognostic value of the abnormal immunolabeling of the analyzed proteins will be established after an adequate follow-up period of this same cohort of patients.

RESUMEN

A prospective study of male soccer injuries among 12 teams playing at the highest competition level was carried out in Finland in 1993. Overall, two out of three players were injured during the whole season. The injury incidence per 1000 playing hours among injured players and all players during games was higher than during practice, 14.2 vs. 11.3 and 2.3 vs. 1.8, respectively. The lower extremity was involved in 76% of the injuries. Thigh injuries were most frequent (22%), whereas overuse injuries were scarce (6%). Eighteen per cent of the injured players needed surgery and in most cases (58%) the reason for surgery was a knee injury. Sixteen per cent of all injured players were absent from soccer for more than 1 month after the injury. The mean absence time was 17 days for all and 84 days for operatively treated players.

RESUMEN

Cell proliferation of transitional cell bladder cancer (TCC) was determined by MIB-1 immunolabeling, volume-corrected mitotic index (M/V index) and S-phase fraction measurement in 207 patients with superficial (Ta-T1) bladder cancer. The results were compared to T category, WHO grade and DNA-ploidy. The MIB-1 score was related to T category (P < 0.001), WHO grade (P < 0.001), DNA ploidy (P < 0,0001), M/V index (P < 0.0001) and fraction of cells in S phase (P < 0.0001). The mean MIB-1 score was 6.37% for G1, 14.59% for G2 and 28.59% for G3 carcinomas (P < 0.001). The MIB-1 score for Ta tumors was 9.24% and for T1 tumors 25.34% (P < 0.001). The M/V index was 3.9 for G1, 11.5 for G2 and 25.9 for G3 tumors (P < 0.0001). The M/V index for Ta tumors was 6.4 and 25.3 for T1 tumors (P < 0.0001). WHO grade 1 tumors had 7.7%, grade 2 tumors 13.8% and grade 3 tumors 21.8% of cells in S phase (P < 0.001). Of grade 1 tumors, 97% were diploid and 3% aneuploid, and 78% of grade 2 tumors were diploid and 22% aneuploid. Of grade 3 tumors, 30% were diploid and 70% aneuploid (P < 0.001). Of Ta tumors, 92% were diploid and 8% aneuploid, respectively, whereas 40% of T1 tumors were diploid and 60% aneuploid (P < 0.0001). The results show that quantitative cell proliferation indices are associated with T category and WHO grade in superficial bladder cancer. The prognostic value of the S-phase fraction and mitotic index has been demonstrated in several previous analyses of prognostic factors while the value of MIB-1 score on bladder cancer prognosis remains to be established in further follow-up studies.

RESUMEN

Archival biopsy specimens from transitional-cell bladder cancers (n = 222) were analysed immunohisto-chemically for expression of retinoblastoma (Rb) gene protein. The intensity of staining for Rb protein and the fraction of positive nuclei were analysed and related to several other prognostic factors and survival. Six per cent of the tumours were totally negative for Rb protein and abnormal (weak) expression was found in 40% of cases. The fraction of positive nuclei and abnormal expression (weak) were highly significantly interrelated (P < 0.0001). A low value for the fraction of Rb-protein-positive nuclei was related to a large fraction in S phase (P = 0.001), high mitotic index (P = 0.016) and overexpression of epidermal growth factor receptor (P = 0.034) and p53 protein (P = 0.019). A normal Rb protein expression pattern was related to low S-phase values (P = 0.0001) whereas over-expression of p53 was related to high S-phase values (P = 0.0077). Morphometrically measured nuclear atypia and the fraction of Rb-protein-positive nuclei were negatively correlated (P < 0.05). In univariate survival analysis altered expression of Rb protein (P = 0.07) and low frequency (< or = 50%) of Rb-protein-positive nuclei (P = 0.0128) predicted a poor outcome. In a multivariate analysis, reduced expression of Rb protein had no independent prognostic value over T category, papillary status and the size of the S-phase fraction. The results show that tumor-suppressor genes Rb and p53 participate in the growth regulation of human bladder cancer cells in vivo and accordingly modify the prognosis.
