Analyses of registry data of patients with anti-GBM and antineutrophil cytoplasmatic antibody-associated (ANCA) vasculitis treated with or without therapeutic apheresis.

Therapeutic apheresis (TA) as a treatment for antibody-associated vasculitis (AAV) was questioned by the PEXIVAS although the MEPEX study favored TA. The aim of this study was to evaluate the efficacy of TA to improve renal function in patients consecutively included in the WAA-apheresis registry versus patients not treated with TA. MATERIALS AND METHODS: Included were 192 patients that suffered from anti-glomerular basement membrane disease (anti-GBM, n = 28) and antineutrophil cytoplasmic antibody-associated vasculitis of MPO or PR3 origin. Of these 119 had performed TA and the other 73 had not performed TA for theses diagnoses (CTRL). RESULTS: Elderly had an increased risk to die within 12 months (p = 0.002). All 28 anti-GBM had renal involvement, 21 dialysis dependent. At 3 month nine (36 %) did not need dialysis. Baseline data regarding renal function of AAV patients, subtype MPO and PR3, were worse in the TA groups than in CTRL. Recovery out of dialysis was better for the PR3-TA group compared with 1) the controls of MEPEX (RR 0.59, CI 0.43-0.80) and 2) the MPO-TA patients (RR 0.28, CI 0.12-0.68). The MPO-TA recovered similarly as the MEPEX-CTRL. Renal function improved most for TA-patients from baseline during the first 3 months (MPO-TA and PR3-TA) and stabilized thereafter and less for MPO-CTRL and PR3-CTRL. CONCLUSION: PR3-TA patients seem to have best chances to get out of dialysis. PR3-TA and MPO-TA improved residual renal function better than CTRL. The present study recommends reconsiderations to use TA for AAV especially those with PR3-vasculitis with severe renal vasculitis.

Evaluation of health and quality of life in apheresis patients - data from the WAA register.

OBJECTIVE: The World Apheresis Association (WAA) register contains data from more than 89 000 apheresis procedures in more than 12,000 patients. The aim of this study was to evaluate functional health and quality of life (QoL) in patients during apheresis treatment. MATERIAL AND METHODS: Estimates of health condition (HC) were made in 40,445 and of QoL in 22112 apheresis procedures. This study focused on a 10-step graded evaluation of HC (scale from: 'bedridden, unable to eat' to a level of 'athletic competition') and self-assessment of QoL (scale from: worst ever '0' to best ever '10'). Data were compared in relation to various apheresis procedures and if the patient underwent the first or subsequent apheresis procedure. RESULTS: Of the patients treated with plasma exchange (PEX) with centrifugation technique (n = 15787) 10% were 'bedridden, unable to come out of bed' while for patients treated with plasma filtration technique (n = 1018) the percentage was 27%. During the first procedure these figures were 16% and 30%, respectively. Self-estimates of QoL were graded 'zero' or '1' in 1.6% of patients during the first apheresis procedure; At the first contact patients undergoing PEX graded like this in 4.3%. CONCLUSION: Many of the patients undergoing apheresis treatment have poor HC and QoL at the start of therapy. Of all therapeutic apheresis procedures patients undergoing PEX had the lowest score of QoL.

Association between breastfeeding and better preserved cognitive ability in an elderly cohort of Finnish men.

BACKGROUND: Being breastfed in infancy has been shown to benefit neurodevelopment. However, whether the benefits persist to old age remains unclear. METHODS: We examined the associations between breastfeeding and its duration on cognitive ability in young adulthood and old age, and on aging-related cognitive change over five decades. In total, 931 men from the Helsinki Birth Cohort Study born in 1934-1944 in Finland took the Finnish Defence Forces Basic Intellectual Ability Test (total and verbal, arithmetic and visuospatial subtest scores) twice, at ages 20.2 and 67.9 years, and had data on breastfeeding (yes v. no) and its duration ('never breastfed', 'up to 3', '3 to 6' and '6 or more months'). Linear and mixed model regressions tested the associations. RESULTS: At 20.2 years, breastfed men had higher cognitive ability total and visuospatial subtest scores [mean differences (MDs) ranged between 3.0-3.9, p values < 0.013], and its longer duration predicted higher cognitive ability total and arithmetic and visuospatial subtest scores (MDs ranged between 3.0 and 4.8, p values < 0.039). At 67.9 years, breastfed men had higher total cognitive ability and all subtest scores (MDs ranged between 2.6 and 3.4, p values < 0.044) and its longer duration predicted all cognitive ability scores (MDs ranged between 3.1 and 4.7, p values < 0.050). Verbal subtest scores decreased over five decades in men who were never breastfed or were breastfed for 3 months or less, and increased in those breastfed for longer than 3 months. CONCLUSIONS: Neurodevelopmental advantages of breastfeeding and its longer duration persist into old age, and longer duration of breastfeeding may benefit aging-related change, particularly in verbal reasoning ability.

Cardiovascular fitness in late adolescent males and later risk of serious non-affective mental disorders: a prospective, population-based study.

BACKGROUND: Cardiovascular fitness in late adolescence is associated with future risk of depression. Relationships with other mental disorders need elucidation. This study investigated whether fitness in late adolescence is associated with future risk of serious non-affective mental disorders. Further, we examined how having an affected brother might impact the relationship. METHOD: Prospective, population-based cohort study of 1 109 786 Swedish male conscripts with no history of mental illness, who underwent conscription examinations at age 18 between 1968 and 2005. Cardiovascular fitness was objectively measured at conscription using a bicycle ergometer test. During the follow-up (3-42 years), incident cases of serious non-affective mental disorders (schizophrenia and schizophrenia-like disorders, other psychotic disorders and neurotic, stress-related and somatoform disorders) were identified through the Swedish National Hospital Discharge Register. Cox proportional hazards models were used to assess the influence of cardiovascular fitness at conscription and risk of serious non-affective mental disorders later in life. RESULTS: Low fitness was associated with increased risk for schizophrenia and schizophrenia-like disorders [hazard ratio (HR) 1.44, 95% confidence interval (CI) 1.29-1.61], other psychotic disorders (HR 1.41, 95% CI 1.27-1.56), and neurotic or stress-related and somatoform disorders (HR 1.45, 95% CI 1.37-1.54). Relationships persisted in models that included illness in brothers. CONCLUSIONS: Lower fitness in late adolescent males is associated with increased risk of serious non-affective mental disorders in adulthood.

Distribution of indications and procedures within the framework of centers participating in the WAA apheresis registry.

The WAA apheresis registry was established in 2003 and an increasing number of centers have since then included their experience and data of their procedures. The registry now contains data of more than 74,000 apheresis procedures in more than 10,000 patients. This report shows that the indications for apheresis procedures are changing towards more oncological diagnoses and stem cell collections from patients and donors and less therapeutic apheresis procedures. In centers that continue to register, the total extent of apheresis procedures and patients treated have expanded during the latest years.

Validation and development of MTH1 inhibitors for treatment of cancer.

BACKGROUND: Previously, we showed cancer cells rely on the MTH1 protein to prevent incorporation of otherwise deadly oxidised nucleotides into DNA and we developed MTH1 inhibitors which selectively kill cancer cells. Recently, several new and potent inhibitors of MTH1 were demonstrated to be non-toxic to cancer cells, challenging the utility of MTH1 inhibition as a target for cancer treatment. MATERIAL AND METHODS: Human cancer cell lines were exposed in vitro to MTH1 inhibitors or depleted of MTH1 by siRNA or shRNA. 8-oxodG was measured by immunostaining and modified comet assay. Thermal Proteome profiling, proteomics, cellular thermal shift assays, kinase and CEREP panel were used for target engagement, mode of action and selectivity investigations of MTH1 inhibitors. Effect of MTH1 inhibition on tumour growth was explored in BRAF V600E-mutated malignant melanoma patient derived xenograft and human colon cancer SW480 and HCT116 xenograft models. RESULTS: Here, we demonstrate that recently described MTH1 inhibitors, which fail to kill cancer cells, also fail to introduce the toxic oxidized nucleotides into DNA. We also describe a new MTH1 inhibitor TH1579, (Karonudib), an analogue of TH588, which is a potent, selective MTH1 inhibitor with good oral availability and demonstrates excellent pharmacokinetic and anti-cancer properties in vivo. CONCLUSION: We demonstrate that in order to kill cancer cells MTH1 inhibitors must also introduce oxidized nucleotides into DNA. Furthermore, we describe TH1579 as a best-in-class MTH1 inhibitor, which we expect to be useful in order to further validate the MTH1 inhibitor concept.

Evaluating equality in psoriasis healthcare: a cohort study of the impact of age on prescription of biologics.

BACKGROUND: Inequality in healthcare has been identified in many contexts. To the best of our knowledge, this is the first study investigating age inequality in the form of prescription patterns of biologics in psoriasis care. OBJECTIVES: To determine whether patients with psoriasis have equal opportunities to receive biological medications as they age. If patients did not receive equal treatment, a subsequent objective was to determine the magnitude of the disparity. METHODS: A cohort of biologic-naive patients with psoriasis was analysed using Cox proportional hazards models to measure the impact of each additional year of life on the likelihood of initiating biological treatment, after controlling for sex, body mass index, comorbidities, disease activity and educational level. A supporting analysis used a nonparametric graphical method to study the proportion of patients initiating biological treatment as age increased, after controlling for the same covariates. RESULTS: The Cox proportional hazards model resulted in hazard ratios of a 1-year increase in age of 0·96-0·97 depending on calendar-year stratification, which implies that an increase in age of 30 years corresponds to a reduced likelihood of initiating biological treatment by 61·3-67·6%. The estimated proportion of patients initiating biological medication always decreased as age increased, at a statistically significant level. CONCLUSIONS: Patients with psoriasis have fewer opportunities to access biological medications as they age. This result was shown to be applicable at all stages in a patient's life course and was not only restricted to the elderly, although it implies greater disparities as the age difference between patients increases. These results show that inequality in access to biological treatments due to age is prevalent in clinical practice today. Further research is needed to investigate the extent to which this result is influenced by patient preferences.

Adverse events in apheresis: An update of the WAA registry data.

Apheresis with different procedures and devices are used for a variety of indications that may have different adverse events (AEs). The aim of this study was to clarify the extent and possible reasons of various side effects based on data from a multinational registry. The WAA-apheresis registry data focus on adverse events in a total of 50846 procedures in 7142 patients (42% women). AEs were graded as mild, moderate (need for medication), severe (interruption due to the AE) or death (due to AE). More AEs occurred during the first procedures versus subsequent (8.4 and 5.5%, respectively). AEs were mild in 2.4% (due to access 54%, device 7%, hypotension 15%, tingling 8%), moderate in 3% (tingling 58%, urticaria 15%, hypotension 10%, nausea 3%), and severe in 0.4% of procedures (syncope/hypotension 32%, urticaria 17%, chills/fever 8%, arrhythmia/asystole 4.5%, nausea/vomiting 4%). Hypotension was most common if albumin was used as the replacement fluid, and urticaria when plasma was used. Arrhythmia occurred to similar extents when using plasma or albumin as replacement. In 64% of procedures with bronchospasm, plasma was part of the replacement fluid used. Severe AEs are rare. Although most reactions are mild and moderate, several side effects may be critical for the patient. We present side effects in relation to the procedures and suggest that safety is increased by regular vital sign measurements, cardiac monitoring and by having emergency equipment nearby.

Hypermobility among school children aged five to eight years: the Hospital del Mar Criteria gives higher prevalence for hypermobility than the Beighton score.

OBJECTIVES: The purpose was to investigate the distribution of hypermobility among school children aged five to eight years. METHODS: One hundred and twenty-eight participants were assessed using the Beighton score and the Hospital del Mar criteria. RESULTS: With the Beighton score using the cut-off ≥4, the prevalence was 12%, and with the Hospital del Mar criteria the prevalence was 34%. There were significantly higher scores for females on both the Beighton (p=0.01) and Hospital del Mar criteria (p<0.0001). The youngest children aged five to six years scored higher compared with the seven- and eight-year-olds (p=0.016). The knee flexion was most likely to be hypermobile (97%), followed by shoulder rotation (80%), thumb (31%), elbow (27%), metatarsal-phalangeal (16%), hip (15.5%), fingers (10%) or knee (10%), ankle (6%), trunk (4%) and patella (2%). CONCLUSIONS: Gender and probably age must be taken into account when children are assessed for hypermobility. The Hospital del Mar criteria need to be modified for some of the motions.

Functional and muscle morphometric effects of ACL reconstruction. A prospective CT study with 1 year follow-up.

Computed tomography (CT) was used to explore if changes in muscle cross-sectional area and quality after anterior cruciate ligament (ACL) injury and reconstruction would be related to knee function. Fourteen females and 23 males (16-54 years) underwent clinical tests, subjective questionnaires, and CT 1 week before and 1 year after ACL surgery with semitendinosus-gracilis (STG) graft and rehabilitation. Postoperatively, knee laxity was decreased and functional knee measures and subjective patient scores improved. The most obvious remaining deficit was the quadriceps atrophy, which was significantly larger if the right leg was injured. Right-leg injury also tended to cause larger compensatory hypertrophy of the combined knee flexor and tibial internal rotator muscles (preoperatively). The quadriceps atrophy was significantly correlated with the scores and functional tests, the latter also being related to the remaining size of the gracilis muscle. Biceps femoris hypertrophy and, in males only, semimembranosus hypertrophy was observed following the ACL reconstruction. The lack of semimembranosus hypertrophy in the women could, via tibial internal rotation torque deficit, contribute to the less favorable functional and subjective outcome recorded for the women. The results indicate that the quadriceps, the combined knee flexor/tibial internal rotator muscles, side of ACL injury, and sex are important to consider in rehabilitation after STG graft.

Remote THz generation from two-color filamentation: long distance dependence.

Remote terahertz (THz) generation from two-color filamentation is investigated as a function of the onset position of filaments. THz signals emitted by filaments produced at distances up to 55 m from the laser source were measured. However, from 9 m to 55 m, the THz signal decayed monotonically for increasing onset positions. With a simple calculation, the dominant factors associated to this decay were identified as group velocity mismatch of the two-color pulses and linear diffraction induced by focusing and propagating the second harmonic pulse.

Asymptomatic peripheral arterial disease: is pharmacological prevention of cardiovascular risk cost-effective?

Peripheral arterial disease (PAD) is associated with an increased risk of early death in cardiovascular (CV) disease. The majority of PAD subjects are asymptomatic with a prevalence of 11 per cent among the elderly. Long-term drug prevention aiming to minimize disease progression and CV events in these subjects is probably beneficial, but expensive. The purpose of this analysis was to evaluate the cost-effectiveness of pharmacological risk reduction in subclinical PAD. Long-term costs and quality-adjusted life years (QALYs) were estimated by employing a decision-analytic model for ACE-inhibitor, statin, aspirin and non-aspirin anti-platelet therapy. Rates of CV events without treatment were derived from epidemiological studies and event rate reduction were retrieved from clinical trials. Costs and health-related quality of life estimates were obtained from published sources. All four drugs reduced CV events. Using ACE-inhibition resulted in a heart rate (HR) of 0.67 (95% CI: 0.55-0.79), statins 0.74 (0.70-0.79), and clopidogrel 0.72 (0.43-1.00). Aspirin had a HR of 0.87 and the 95% CI passed included one (0.72-1.03). ACE-inhibition was associated with the largest reduction in events leading to the highest gain in QALYs (7.95). Furthermore, ACE-inhibitors were associated with the lowest mean cost €40.556. In conclusion, while all drugs reduced CV events, ACE-inhibition was the most cost-effective. These results suggest that we should consider efforts to identify patients with asymptomatic PAD and, when identified, offer ACE-inhibition.

Young men exempted from compulsory military or civil service in Finland--a group of men in need of psychosocial support?

AIMS: The aim of this study was to find out whether young men exempted from compulsory military or civil service constitute a group of young men in need of psychosocial support from the social and health services. METHODS: The study involved a total of 356 men exempted from military or civil service and 440 young men conscripted into service. The research data were collected using questionnaires and register data. RESULTS: Men exempted from military or civil service differed from conscripts in terms of psychosocial well-being. Compared with conscripts, they had already been in a more disadvantaged position with regard to their childhood living conditions. As young adults, they had met with a greater number of mental and social problems than conscripts: alcohol-related problems, unemployment, financial problems, homelessness, lack of social support and psychological distress. Young men exempted from service typically suffered from an accumulation of problems. Diverse problems were common particularly among men who had interrupted their service. There was a moderate correlation between current and childhood adversities. CONCLUSIONS: Men exempted from military or civil service comprise a group with a wide range of psychosocial problems and are a target group for supportive interventions. Special attention should be paid to the prevention of problems and promotion of well-being of men who interrupt their service. The accumulation of problems poses a challenge for the development of such interventions.

Cost-effectiveness of gallbladder histopathology after cholecystectomy for benign disease.

BACKGROUND: The prevalence of incidental gallbladder cancer is low when performing cholecystectomy for benign disease. The performance of routine or selective histological examination of the gallbladder is still a subject for discussion. The aim of this study was to assess the cost-effectiveness of these different approaches. METHODS: Four management strategies were evaluated using decision-analytical modelling: no histology, current selective histology as practised in Sweden, macroscopic selective histology, and routine histology. Healthcare costs and life-years were estimated for a lifetime perspective and combined into incremental cost-effectiveness ratios (ICERs) to assess the additional cost of achieving an additional life-year for each management strategy. RESULTS: In the analysis of the four strategies, current selective histology was ruled out due to a higher ICER compared with macroscopic selective histology, which showed better health outcomes (extended dominance). Comparison of routine histology with macroscopic selective histology resulted in a gain of 12 life-years and an incremental healthcare cost of approximately €1 000 000 in a cohort of 10 000 patients, yielding an estimated ICER of €76 508. When comparing a macroscopic selective strategy with no histological assessment, 50 life-years would be saved and the ICER was estimated to be €20 708 in a cohort of 10 000 patients undergoing cholecystectomy. CONCLUSION: A macroscopic selective strategy appears to be the most cost-effective approach.

Treatment patterns and survival in patients with hepatocellular carcinoma in the Swedish national registry SweLiv.

BACKGROUND: Consistent data on clinical features, treatment modalities and long-term survival in patients with hepatocellular carcinoma (HCC) using nationwide quality registers are lacking. This study aimed to describe treatment patterns and survival outcomes in patients diagnosed with HCC using a national maintained database. METHODS: Characteristics and treatment patterns in patients diagnosed with HCC and registered in the national register of liver and bile duct tumours (SweLiv) between 2009 and 2016 were reviewed. Overall survival (OS) was estimated using Kaplan-Meier analysis and the log rank test to compare subgroups for clinical features, treatment modalities and outcomes according to the year of treatment. RESULTS: A total of 3376 patients with HCC were registered over 8 years, 246 (7·3 per cent) of whom underwent transplantation. Some 501 (14·8 per cent) and 390 patients (11·6 per cent) had resection and ablation as primary treatment. Transarterial chemoembolization and systemic sorafenib treatment were intended in 476 (14·1 per cent) and 426 patients (12·6 per cent) respectively; the remaining 1337 (39·6 per cent) were registered but referred for best supportive care (BSC). The 5-year survival rate was approximately 75 per cent in the transplantation group. Median OS was 4·6 (i.q.r. 2·0 to not reached) years after resection and 3·1 (2·3-6·7) years following ablation. In patients referred for palliative treatment, median survival was 1·4 (0·8-2·9), 0·5 (0·3-1·2) and 0·3 (0·1-1·0) years for the TACE, sorafenib and BSC groups respectively (P < 0·001). Median survival was 0·9 years for the total HCC cohort in 2009-2012, before publication of the Swedish national treatment programme, increasing to 1·4 years in 2013-2016 (P < 0·001). CONCLUSION: The survival outcomes reported were in line with previous results from smaller cohorts. The introduction of national guidelines may have contributed to improved survival among patients with HCC in Sweden.

ANTECEDENTES: Se carece datos consistentes acerca de las características clínicas, modalidades terapéuticas y supervivencia a largo plazo en pacientes con carcinoma hepatocelular (hepatocellular carcinoma, HCC) basados en registros de calidad de ámbito nacional. El objetivo de este estudio fue describir los patrones de tratamiento y los resultados de supervivencia en pacientes diagnosticados de HCC usando una base de datos nacional. MÉTODOS: Se revisaron las características de los pacientes y los patrones de tratamiento en pacientes con un diagnóstico de HCC incluidos en el registro nacional de tumores de hígado y vías biliares (SweLiv) entre 2009 y 2016. La supervivencia global (overall sirvival, OS) se analizó mediante el método de Kaplan-Meier y test de log-rank para la comparación de subgrupos según las características clínicas de los pacientes, las modalidades de tratamiento y los resultados en función del año de tratamiento. RESULTADOS: Durante un periodo de 7 años, se incluyeron en el registro un total de 3.076 pacientes con HCC, 246 de los cuales recibieron un trasplante (7,2%). Se practicó resección y ablación como tratamiento primerio en 501 (14,8%) y 390 (11,6%) pacientes, respectivamente. La quimioembolización (TACE) y el tratamiento sistémico con sorafenib se efectuó en 476 (14,1%) y 426 (12,6%) pacientes, respectivamente; los 1.337 pacientes restantes (40,0%) fueron incluidos en la base de datos pero se derivaron para recibir el mejor tratamiento de soporte. La tasa de supervivencia a los 5 años fue del 75% en el grupo trasplantado. La mediana de OS fue de 4,6 años (rango intercuartílico, interquartile range, IQR 2,0-no alcanzado) tras la resección y de 3,1 años (IQR 2,3-6,7) tras la ablación. En los pacientes derivados para tratamiento paliativo, la mediana de supervivencia fue de 1,4 años (IQR 0,8-2,9), 0,5 años (IQR 0,2-1,2) y 0,3 años (IQR 0,1-1,0) para los grupos de TACE, sorafenib y mejor tratamiento de soporte, respectivamente (P < 0,001). La mediana de supervivencia para toda la cohorte de HCC en 2009-2012 fue de 0,9 años antes de la publicación del programa de nacional de tratamiento sueco, aumentando a 1,4 años en 2013-2016 (P <0,001). CONCLUSIÓN: Los resultados de supervivencia referidos eran consistentes con resultados previos obtenidos en cohortes más pequeñas; la introducción de guías nacionales puede haber contribuido a mejorar la supervivencia de los pacientes con HCC en Suecia.

Depressive symptoms and suicidal ideation during isotretinoin treatment: a 12-week follow-up study of male Finnish military conscripts.

OBJECTIVE: To investigate the putative association between isotretinoin treatment and depressive symptoms or suicidal ideation among Finnish male military conscripts. METHODS; Consecutive acne patients were enrolled into an uncontrolled, prospective 12-week follow-up study conducted at the Central Military Hospital, Helsinki, Finland. Of the 135 patients prescribed isotretinoin, 126 (93.3%) completed the follow-up. Depression and suicidal ideation were investigated with the Beck Depression Inventory (BDI) at baseline, weeks 4-6, and weeks 10-12. RESULTS: BDI mean score was low at baseline and declined further significantly (p < 0.001) during the follow-up from 3.0 (SD 3.948) to 1.8 (SD 3.783) among patients on isotretinoin. Moreover, the proportion of patients with clinically significant depressive symptoms (BDI > or= 10) declined non-significantly from 7.1 % to 3.2 %. Suicidal ideation was reported by 17 (13.5 %) patients at baseline and 9 (7.1%) patients at the end of the follow-up (NS). During the follow-up, one non-depressed patient attempted suicide while intoxicated by alcohol. CONCLUSION: On group level, isotretinoin seems not to be typically associated with treatment-emergent depression or suicidal ideation among young men. However, the possibility that individual patients may be susceptible for mood effects of isotretinoin as a rare idiosyncratic reaction can not be excluded.

Cost-effectiveness of endarterectomy in patients with asymptomatic carotid artery stenosis.

BACKGROUND: Long-term health outcomes and costs are important when deciding whether a strategy of carotid endarterectomy in addition to best medical management should be recommended for patients with asymptomatic carotid artery stenosis. This study investigated the cost-effectiveness of such a strategy compared with a strategy of best medical management alone. METHODS: Based on data from the randomized Asymptomatic Carotid Surgery Trial (ACST), a national vascular database and other published sources, expected costs and health outcomes in terms of quality-adjusted life years (QALYs) of both treatment strategies were estimated using decision-analytical modelling. Cost-effectiveness was established for a Swedish setting from a societal perspective. RESULTS: Base-case analysis showed that the incremental cost per QALY of a strategy with carotid endarterectomy for 65- and 75-year-old men (women) was 34,557 euros (311,133 euros) and 58,930 euros (779,776 euros) respectively. Sensitivity analyses indicated that the duration of the treatment effect after 5 years of follow-up in the ACST was important for the cost-effectiveness results. CONCLUSION: Carotid endarterectomy in addition to best medical management can be considered cost-effective in men aged 73 years or less but is less likely to be cost-effective in older men or in women.

Increase of serum C-reactive protein is an early indicator of subsequent symptomatic anastomotic leakage after anterior resection.

OBJECTIVE: This prospective study investigated the factors which might indicate anastomotic leakage after low anterior resection. METHOD: Thirty-three patients who underwent anterior resection for rectal carcinoma (n = 32) and severe dysplasia (n = 1), were monitored daily by serum C-reactive protein (CRP) and white blood cell count (WBC) estimations until discharge from hospital. Computed tomography (CT) scans were performed on postoperative days 2 and 7 and the amount of presacral fluid collection was assessed. All patients had a pelvic drain and the volume of drainage was measured daily. RESULTS: The level of the anastomosis was at a median 5 cm (3-12 cm) above the anal verge. There was no 30-day mortality. Nine (27.2%) of the 33 patients developed a symptomatic anastomotic leakage which was diagnosed at a median of 8 days (range 4-14) postoperatively. The serum CRP was increased in patients who leaked from postoperative day 2 onwards (P = 0.004 on day 2; P < 0.001 on day 3-8). The WBC was decreased in preoperatively irradiated patients on days 1-5 (P

Identification of recognition sites for myc/max/mxd network proteins by a whole human chromosome 19 selection strategy.

In this study, we have identified 20 human sequences containing Myc network binding sites in a library from the whole human chromosome 19. We demonstrated binding of the Max protein to these sequences both in vitro and in vivo. The majority of the identified sequences contained one or several CACGTG or CATGTG E-boxes. Several of these sites were located within introns or in their vicinity and the corresponding genes were found to be up- or down-regulated in differentiating HL-60 cells. Our data show the proof of principle for using this strategy in identification of Max target genes, and this method can also be applied for other transcription factors.
