Background: Metastasectomy is probably underused in metastatic colorectal cancer. The aim of this study was to investigate the effect of centralized repeated assessment on resectability rate of liver metastases. Methods: The prospective RAXO study was a nationwide study in Finland. Patients with treatable metastatic colorectal cancer at any site were eligible. This planned substudy included patients with baseline liver metastases between 2012 and 2018. Resectability was reassessed by the multidisciplinary team at Helsinki tertiary referral centre upfront and twice during first-line systemic therapy. Outcomes were resectability rates, management changes, and survival. Results: Of 812 patients included, 301 (37.1 per cent) had liver-only metastases. Of these, tumours were categorized as upfront resectable in 161 (53.5 per cent), and became amenable to surgery during systemic treatment in 63 (20.9 per cent). Some 207 patients (68.7 per cent) eventually underwent liver resection or ablation. At baseline, a discrepancy in resectability between central and local judgement was noted for102 patients (33.9 per cent). Median disease-free survival (DFS) after firstresection was 20 months and overall survival (OS) 79 months. Median OS after diagnosis of metastatic colorectal cancer was 80, 32, and 21 months in R0-1 resection, R2/ablation, and non-resected groups, and 5-year OS rates were 68, 37, and 9 per cent, respectively. Liver and extrahepatic metastases were present in 511 patients. Of these, tumours in 72 patients (14.1 per cent) were categorized as upfront resectable, and 53 patients (10.4 per cent) became eligible for surgery. Eventually 110 patients (21.5 per cent) underwent liver resection or ablation. At baseline, a discrepancy between local and central resectability was noted for 116 patients (22.7 per cent). Median DFS from first resection was 7 months and median OS 55 months. Median OS after diagnosis of metastatic colorectal cancer was 79, 42, and 17 months in R0-1 resection, R2/ablation, and non-resected groups, with 5-year OS rates of 65, 39, and 2 per cent, respectively. Conclusion: Repeated centralized resectability assessment in patients with colorectal liver metastases improved resection and survival rates. [ABSTRACT FROM AUTHOR]

Objective: To evaluate whether a nationwide prenatal anomaly screening programme improves detection rates of univentricular heart (UVH) and transposition of great arteries (TGA), and whether maternal risk factors for severe fetal heart disease affect prenatal detection.Design: Population-based cohort study.Setting: Nationwide data from Finnish registries 2004-14.Population: A total of 642 456 parturients and 3449 terminated pregnancies due to severe fetal anomaly.Methods: Prenatal detection rates were calculated in three time periods (prescreening, transition and screening phase). The effect of maternal risk factors (obesity, in vitro fertilisation, pregestational diabetes and smoking) was evaluated.Main Outcome Measures: Change in detection rates and impact of maternal risk factors on screening programme efficacy.Results: In total, 483 cases of UVH and 184 of TGA were detected. The prenatal detection rate of UVH increased from 50.4% to 82.8% and of TGA from 12.3% to 41.0% (P < 0.0001). Maternal risk factors did not affect prenatal detection rate, but detection rate differed substantially by region.Conclusions: A nationwide screening programme improved overall UVH and TGA detection rates, but regional differences were observed. Obesity or other maternal risk factors did not affect the screening programme efficacy. The establishment of structured guidelines and recommendations is essential when implementing the screening programme. In addition, a prospective screening register is highly recommended to ensure high quality of screening.Tweetable Abstract: Implementation of a nationwide prenatal anomaly screening improved detection rates of UVH and TGA.

Background and Objectives: Large-scale genome-wide studies of chronic hydrocephalus have been lacking. We conducted a genome-wide association study (GWAS) in normal pressure hydrocephalus (NPH)., Methods: We used a case-control study design implementing FinnGen data containing 473,691 Finns with genotypes and nationwide health records. Patients with NPH were selected based on ICD-10 G91.2 diagnosis. To select patients with idiopathic NPH (iNPH) for sensitivity analysis, we excluded patients with a potentially known etiology of the condition using an algorithm on their disease history. The controls were the remaining non-hydrocephalic participants. For a replication analysis, the NPH cohort from UK Biobank (UKBB) was used., Results: We included 1,522 patients with NPH (mean age 72.2 years, 53% women) and 451,091 controls (mean age 60.5 years, 44% women). In the GWAS comparing patients with NPH with the controls, we identified 6 gene regions significantly ( p < 5.0e-8) associated with NPH that replicated in a meta-analysis with UKBB (NPH n = 173). The top loci near the following genes were rs7962263, SLCO1A2 (odds ratio [OR] 0.71, 95% CI 0.65-0.78, p = 1.0e-14); rs798495, AMZ1 / GNA12 (OR 1.29, 95% CI 1.20-1.39, p = 2.9e-12); rs10828247, MLLT10 (OR 0.77, 95% CI 0.71-0.83, p = 1.5e-11); rs561699566 and rs371919113, CDCA2 (OR 0.76, 95% CI 0.70-0.82, p = 1.5e-11); rs56023709, C16orf95 (OR 1.24, 95% CI 1.16-1.33, p = 3.0e-9); and rs62434144, PLEKHG1 (OR 1.23, 95% CI 1.14-1.32, p = 1.4e-8). In the sensitivity analysis comparing only patients with iNPH (n = 1,055) with the controls (n = 451,091), 4 top loci near the following genes remained significant: rs7962263, SLCO1A2 (OR 0.70, 95% CI 0.63-0.78, p = 2.1e-11); rs10828247, MLLT10 (OR 0.74, 95% CI 0.62-0.82, p = 4.6e-10); rs798511, AMZ1 / GNA12 (OR 1.28, 95% CI 1.17-1.39, p = 1.7e-8); and rs56023709, C16orf95 (OR 1.28, 95% CI 1.17-1.39, p = 1.7e-8)., Discussion: We identified 6 loci significantly associated with NPH in the thus far largest GWAS in chronic hydrocephalus. The genes near the top loci have previously been associated with blood-brain barrier and blood-CSF barrier function and with increased lateral brain ventricle volume. The effect sizes and allele frequencies remained similar in NPH and iNPH cohorts, indicating the identified loci are risk determinants for iNPH and likely not explained by associations with other etiologies. However, the exact role of these loci is still unknown, warranting further studies.

Importance: The incidence of Zenker diverticulum has been established; previous estimates have been extrapolated from small institutional cohorts., Objective: To describe the population-wide incidence of Zenker diverticulum over a 20-year period and characterize management strategies across specialties and treatment settings., Design, Setting, and Participants: This retrospective national cohort study was conducted from January 1, 1996, through December 31, 2015, and reviewed patient records from the Care Register for Healthcare in Finland, from which patients with Zenker diverticulum were identified. The data were analyzed in October 2021., Exposures: Zenker diverticulum., Main Outcome and Measure: The incidence of Zenker diverticulum per 100 000 person-years., Results: A total of 2736 patients (median [IQR] age at diagnosis 72.0 [19-106] years; 1278 women [46.7%]) were identified, making the annual incidence of Zenker diverticulum in Finland 2.9/100 000 person-years. Men had higher incidence (3.7/100 000 person-years) compared with women (2.3/100 000 person-years), with an incidence rate ratio of 1.61 (95% CI, 1.48-1.76; P < .001). Within the study population, 1044 patients (38.2%) underwent surgical treatment and 227 (8.3%) underwent 2 or more surgeries. The choice of initial operative approach depended on the medical specialty (Cramer V = 0.41) and on specific catchment area (Cramer V = 0.41). Overall, endoscopic approaches for initial operations were most popular., Conclusions and Relevance: The cohort study results found that the incidence of Zenker diverticulum was 2.9/100 000 person-years. Most patients with Zenker diverticulum did not undergo definitive therapy. Some hospital districts and some medical specialties were more likely to opt for conservative treatment than others. The choice of operative approach depended more on physician-level factors rather than patient profiles.

Background: Substantial variation in health care costs for malignant pleural mesothelioma (MPM) has previously been identified., Materials and Methods: We analyzed the changes in health care costs in MPM in Finland during 2002-2012. Finland has low-threshold public health care and a mandatory Workers' Compensation scheme that covers all occupational-related disease expenses. The costs include treatment costs for inpatients, hospice care, medication costs, rehabilitation costs, and travel costs. All costs are expressed in 2012 prices, adjusted using the consumer price index., Results: A total of 907 MPM patients were included in the study. Mean duration of inpatient episodes increased 7% per year from 2002 to 2012, correlating with total costs (R 2  = 0.861, p < 0.05). The annual total costs for treatment increased from 1.7 to 4.3 m€ during the study period and the cost per patient from 27 000 to 43 000 €. The overall costs increased progressively by the number of procedures performed. In patients who had been compensated for occupational cause by Workers' Compensation Center, only 36% of the overall care costs were billed from the insurance company. Billing of inpatient costs was 86% in these patients., Conclusion: During the study period, we found that the costs of MPM increased more than the average health care costs. This may be because of advanced diagnostic workup or more costly treatment (e.g., pemetrexed). Moreover, only one-third of all health care costs are charged to Workers' Compensation Insurance., (© 2021 The Authors.

Introduction: Newborn infants with transposition of the great arteries (d-TGA) need immediate care for an optimal outcome. This study comprised a nationwide 11-year population-based cohort of d-TGA infants, and assessed whether the implementation of a nationwide systematic fetal screening program, or other perinatal, or perioperative factors, are associated with mortality or an increased need for hospital care., Material and Methods: The national cohort consisted of all live-born infants with simple d-TGA (TGA ± small ventricular septal defect, n = 127) born in Finland during 2004-2014. Data were collected from six national registries. Prenatal diagnosis and perinatal and perioperative factors associated with mortality and length of hospitalization were evaluated., Results: Preoperative mortality was 7.9%, and the total mortality was 8.7%. The prenatal detection rate increased after introducing systematic fetal anomaly screening from 5.0% to 37.7% during the study period (P < .0001), but the total mortality rate remained unchanged. All prenatally diagnosed infants (n = 27) survived. Lower gestational age (odds ratio 0.68, P = .012) and higher maternal age at birth (odds ratio 1.16, P = .036) were associated with increased mortality in multivariable analysis. Older infant age at time of operation (P = .002), longer aortic clamp time (P < .001), and higher maternal body mass index (P = .027) were associated with longer initial hospital stay. An extended need for hospital care during the first year of life was multi-factorial., Conclusions: In our cohort, none of the prenatally diagnosed d-TGA infants died. As a result of the limited prenatal detection rates, however, the sample size was insufficient to reach statistical significance. The d-TGA infants born with lower gestational age and to older mothers had increased mortality., (© 2020 Nordic Federation of Societies of Obstetrics and Gynecology (NFOG).

Purpose: The Finnish National Esophago-Gastric Cancer Cohort (FINEGO) was established with the aim of identifying factors that could contribute to improved outcomes in oesophago-gastric cancer. The aim of this study is to describe the patients with gastric cancer included in FINEGO., Participants: A total of 10 457 patients with gastric cancer or tumour diagnosis in the Finnish Cancer Registry or the Finnish Patient Registry during 1987-2016 were included in the cohort, with follow-up from Causes of Death Registry until 31 December 2016. All of the participants were at least 18 years of age, and had undergone either resectional or endoscopic mucosal surgery with curative or palliative intent., Findings to Date: Of the 10 457 patients, 90.1% were identified to have cancer in both cancer and patient registries. In all, the median age was 70 at the time of surgery, 54.5% of the patients were men and 64.4% had no comorbidities. Education data were available for 31.1% of the patients, of whom the majority had had <12 years of formal education. Of the 7798 with cancer staging data available, 41.1% had a local cancer. Adenocarcinoma was the most common (94.2%) histological type. Almost all patients underwent open gastrectomy and 214% in hospitals with annual volume of more than 30 gastrectomies per year. A total of 8561 deaths occurred during the study period, of which 6474 were due to oesophago-gastric cancers. The 5-year survival was 34.6% and 5-year cancer-specific survival was 39.7%., Future Plans: The data in FINEGO can be currently used for registry-based research but is being expanded by data extraction from patient records and scanning of histological samples from the Finnish biobanks. Initially, we are planning on studies on the national trends in treatment and mortality, and studies on the demographic factors and their influence on survival., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Purpose: The Finnish National Esophago-Gastric Cancer Cohort (FINEGO) was established to combine the available registry data with detailed patient information to form a comprehensive, retrospective, population-based research platform of surgically treated oesophageal and gastric cancer in Finland. This cohort profile describes the 2045 surgically treated patients with oesophageal cancer included in the FINEGO cohort., Participants: Registry data were collected from the National Cancer, Patient, Education and Death Registries from 1 January 1987 to 31 December 2016. All patients over 18 years of age, who had either curative surgery, palliative surgery or salvage surgery for primary cancer in the oesophagus are included in this study., Findings to Date: 2045 patients had surgery for oesophageal cancer in the selected time period. 67.2% were man, and the majority had only minor comorbidities. The proportions of adenocarcinomas and squamous cell carcinomas were 43.1% and 44.4%, respectively, and 12.5% had other or missing histology. Only about 23% of patients received neoadjuvant therapy. Oesophagectomy was the treatment of choice and most patients were treated at low-volume centres, but median annual hospital volume increased over time. Median overall survival was 23 months, 5-year survival for all patients in the cohort was 32.9% and cancer-specific survival was 36.5%., Future Plans: Even though Finland only has a population of 5.5 million, surgery for oesophageal carcinoma has not been centralised and therefore previously reported results have mostly been small, single-centre cohorts. Because of FINEGO, we now have a population-based, unselected cohort of surgically treated patients, enabling research on national trends over time regarding oesophageal cancer, including patient characteristics, tumour histology, stage and neoadjuvant treatment, surgical techniques, hospital volumes and patient mortality. Data collection is ongoing, and the cohort will be expanded to include more detailed data from patient records and national biobanks., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background: Malignant pleural mesothelioma (MPM) is a rare occupational cancer with a poor prognosis. Even with a multimodality treatment approach, the treatment outcomes remain unsatisfactory. The use of asbestos has been banned in most developed countries, but MPM continues to be a significant occupational disease also in these countries. Aim of this study is to identify modern epidemiology and assess equality in care., Methods: Our study cohort consists of 1010 patients diagnosed with MPM in Finland during 2000-2012. The data were collected from the Finnish Cancer Registry, the National Workers' Compensation Center Registry and the National Registry of Causes of Death, Statistics Finland., Results: Women were diagnosed a mean of 4.5 years later than males (p = .001), but survival did not differ (overall median survival 9.7 months). A workers' compensation claim was more common in males (OR 11.0 [95% CI 7.5-16.2]) and in regions with a major asbestos industry (OR 1.7 [95% CI 1.3-2.2]). One-year and three-year survivals did not differ regionally. Patients without chemotherapy treatment had an inferior survival (RR 1.8 [95% CI 1.5-2.0]). The initial survival benefit gained with pemetrexed was diluted at 51 months., Conclusions: MPM is a disease with a poor prognosis, although chemotherapy appears to improve survival time. Significant gender and regional variation exists among patients, with notable differences in diagnostic and treatment practices. Long-term outcomes with pemetrexed remain indeterminate., Impact: Emphasize centralized consult services for the diagnosis, treatment and support that patients receive for MPM, facilitating equal outcomes and compensation.

Background: Upper extremity deep vein thrombosis represents (UEDVT) 2-3% of all deep vein thrombosis. Catheter directed thrombolysis (CDT) was replaced largely by pharmacomechanical thrombolysis (PMT) in our institution. In this study we compared the immediate and 1-year results as well as the total hospital costs between CDT and PMT in the treatment of UEDVT., Methods: From 2006 to 2013, 55 patients with UEDVT were treated with either CDT or PMT at Helsinki University Hospital. Of them, 43 underwent thoracoscopic rib resection later to relieve phlebography-confirmed vein compression. This patient cohort was prospectively followed up with repeated phlebographies. CDT was performed to 24 patients, and 19 had PMT with a Trellis™ device. Clinical evaluation and vein patency assessment were performed with either phlebography or ultrasound 1 year after the thrombolysis. Primary outcomes were immediate technical success, 1-year vein patency, and costs of the initial treatment., Results: The immediate overall technical success rate, defined as recanalization of the occluded vein and removal of the fresh thrombus, was 91.7% in the CDT group and 100% in the PMT group (n.s.). The median thrombolytic time was significantly longer in CDT patients than that in PMT patients (21.1 vs. 0.33 hr, P < 0.00001). There were no procedure-related complications. The 1-year primary assisted patency rate was similar in both the groups (91.7% and 94.7%). There were no recurrences of clinical DVT. The hospital costs for the acute period were significantly lower in the PMT group than those in the CDT group (medians: 11,476 € and 5,975 € in the CDT and PMT groups, respectively [P < 0.00001])., Conclusions: The clinical results of the treatment of UEDVT with CDT or PMT were similar. However, PMT required shorter hospital stay and less intensive surveillance, leading to lower total costs., (Copyright © 2018 Elsevier Inc. All rights reserved.)

The incidence of thoracic empyema is increasing. Early treatment of empyema should focus on optimal drainage and antibiotics. If conventional therapy fails, surgical intervention has to be considered and approximately 30% of all patients require surgery. In a three-year period (2011-2013), 182 patients were operated at Helsinki University Hospital due to pleural empyema. Thoracoscopic decortication was performed on 44% of the patients and 56% underwent open surgery. After thoracoscopy, the patients had a shorter hospital stay and fewer reoperations. Thoracoscopic decortication should therefore be the first-line procedure in the surgical treatment of pleural empyema.

Study Objective: To report paediatric in-hospital cardiac arrest data according to Utstein style and to determine the effectiveness of cardiopulmonary resuscitation (CPR) in hospitalized children., Design: Retrospective 5-year case series., Setting: Urban, tertiary-care children's hospital., Participants: All patients who sustained cardiopulmonary arrest., Results: Altogether 227 patients experienced a cardiopulmonary arrest during the study period, 109 (48.0%) were declared dead without attempted resuscitation, and CPR was initiated in 118 (52.0%). The incidence of cardiac arrest was 0. 7% of all hospital admissions and 5.5% of PICU admissions; the incidence of CPR attempts was 0.4 and 2.5%, respectively. Most of the CPR attempts (64.4%) took place in the PICU and the most frequent aetiology was cardiovascular (71.2%). The 1-year survival rate was 17.8%. Short duration of external CPR was the best prognostic factor associated with survival. With few exceptions, the Paediatric Utstein Style was found to be applicable for reporting retrospective data from in-hospital cardiac arrests in children., Conclusions: In-hospital cardiopulmonary resuscitation was shown to be an uncommon event in children; the survival rate was similar to earlier studies.

Background: A study was designed to determine which paediatric trauma patients with no detectable vital signs are likely to benefit from cardiopulmonary resuscitation (CPR)., Methods: A 10-year retrospective study of all pulseless patients under 16 years of age with trauma in whom CPR was initiated in a prehospital or in-hospital setting in Southern Finland., Results: Forty-one patients, 25 male and 16 female, were included in this study. The mean age was 7.8 years (range 0.1-15.9 years). Twenty three patients had blunt injuries and three patients had penetrating injuries. The mean Injury Severity Score was 51 (range 25-75). In 15 patients, the arrest was secondary to smoke inhalation, strangulation or electric shock. Resuscitation was initiated at the scene or en route in 28 patients and in 13 patients at the hospital. Five patients received open-chest CPR and 36 patients closed-chest CPR. Spontaneous circulation was restored in four patients with open-chest CPR and in six patients with closed-chest CPR. Two patients had intact survival and one patient survived with moderate disability. The mechanism of traumatic cardiac arrest, initial cardiac rhythm or location of arrest did not seem to affect outcome of CPR., Conclusions: The overall survival rate of paediatric patients with cardiac arrest secondary to trauma is poor. Trauma patients in whom cardiac arrest is caused by respiratory arrest or by thoracoabdominal trauma in the hospital setting may have a chance of survival if a spontaneous circulation is rapidly restored with effective resuscitative measures.

Background: Previous data suggest a favourable association between religion and mortality., Methods: We investigated the association between selected religious groups and all-cause mortality in 1627 eastern Finnish men aged 42-60 years during 1984-1989 as a part of the Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD)., Results: Eastern Orthodox men had a 5.1-fold (95% confidence interval [Cl: 1.98-13.3, P < 0.001) mortality as compared with Lutheran men after adjusting for main confounders. Adjustment for different sets of covariates did not affect the magnitude of relative hazard (RH) notably. Adjusted for the examination year, age, family history of coronary heart disease (CHD), and ischaemia in exercise electrocardiograms, RH was 4.4 (95% CI: 2.5-7.5, P < 0.001) and 4.7 (95% CI: 2.7-8.3, P < 0.001) after an additional adjustment for serum cholesterol, blood leucocytes, plasma fibrinogen, serum triglycerides, maximal oxygen uptake, height, and weight. With adjustment for income, childhood socioeconomic status (SES), and years of education RH for the Orthodox religion was 4.2 (95% CI: 2.4-7.3, P < 0.001) and 4.4 (95% CI: 2.5-7.7; P < 0.001) with depression, helplessness, quality of relationships, marital status and organizational participation, and 4.1 (95% CI: 2.4-7.2, P < 0.001) when adjusted for the use of tobacco and alcohol and the intensity of physical activity. After adjustment for migration because of the war the RH was 4.5 (95% CI: 1.9-10.8, P < 0.001)., Conclusions: Our findings indicate that mortality risk varies substantially by religious affiliation, and this variation cannot be attributed to differences in measures for a wide variety of health, behavioural, socioeconomic, biological, social, and other characteristics.

Wollastonite metasilicate fibers are rather similar in form, length, and diameter, but mineralogically different, to amphibole asbestos fibers. We have studied immunologic findings from 46 men exposed to wollastonite at a limestone quarry for at least 10 years. These workers showed a higher prevalence of positive serum rheumatoid factors than blood donors did. This finding resembles the one detected among asbestos workers. The group of wollastonite workers with radiological signs of pulmonary fibrosis had activities of serum angiotensin-converting enzyme that were similar to those of wollastonite workers without fibrosis. A mortality study of 238 quarry workers with 5,769 person-years was, as expected, nonpositive. It was interesting that one woman with 20 years of exposure to wollastonite and with no other known exposure to fibers revealed a malignant retroperitoneal mesenchymal tumor 30 years after the initial exposure. This kind of very rare tumor is difficult to distinguish from mesothelioma. However, this is only one case, and it is impossible to draw any definite conclusions.
