Abstract
A midinfrared single-photon-counting lidar at 3 µm is presented. The 3 µm photons were upconverted to 790 nm in a periodically poled rubidium-doped KTiOPO4 crystal through intracavity mixing inside a 1064 nm Nd:YVO4 laser and detected using a conventional silicon single-photon avalanche detector (SPAD). The lidar system could distinguish 1 mm deep features on a diffusely reflecting target, limited by the SPAD and time-tagging electronics. This technique could easily be extended to longer wavelengths within the transparency of the nonlinear crystal.

Abstract
The bandwidth and stability limits of the stochastic parallel gradient descent (SPGD) algorithm used for coherent beam combination is investigated by deriving an analytical model for the phase control loop. The analytical model is compared to experiments and numerical simulations using a laboratory tiled coherent beam combination setup. The setup consisted of four sub-beams from fiber-optic collimators and used a backreflected signal as feedback. A rotating phase plate was used to induce phase disturbances into the system. The analytical model compared favorably to numerical simulations and experiments as well as to other studies found in the literature. The results can be used to provide an estimate of the achievable phase control bandwidth of coherent beam combination systems using SPGD as a control algorithm.

Abstract
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.

Abstract
AbstractObjectiveResearch on adolescent adjustment disorder (AD) is scarce. We characterized adolescent outpatients with AD in psychosocial background and treatment received compared with patients with other non-psychotic disorders (OND). Furthermore, we explored precipitant stressors, distress symptoms and behavioral problems among males and females with AD.MethodData were collected prospectively on 290 consecutive psychiatric outpatients, aged 12–22 yrs, at a secondary care clinic in Finland. DSM-III-R diagnoses were assigned, based on all available information, at the end of treatment.ResultsAD was the second most common diagnosis among non-psychotic patients (31% of 290). Compared to OND-patients, those with AD were predominantly female and had less severe psychosocial impairment. In multivariate comparisons school-related stressors, problems with law and restlessness characterized males, and parental illness and internalizing symptoms females with AD. Intensity and duration of treatment of AD-patients varied widely.ConclusionsAdjustment disorder comprised a common clinical entity among adolescent outpatients. Psychiatric assessment and treatment should be individually targeted by taking into account gender-specific stressors and distress symptoms among young people with AD.

Abstract
A single-photon-counting mid-infrared LIDAR is presented. 2.4 µm mid-infrared photons were up-converted to 737 nm by intra-cavity mixing in a periodically poled rubidium-doped KTiOPO4 crystal inside a Nd:YVO4 laser. The up-converted photons were detected by a Si single-photon avalanche photodiode (SPAD). A temporal resolution of 42 ps and a dark count rate of 500 Hz were achieved, limited by the SPAD and ambient light leakage. It allowed for detection of two targets separated by only a few millimeters. This technique is easily extendable to longer wavelengths, limited primarily by the nonlinear crystal transparency.

Abstract
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.

Abstract
Abstract
Problem
The measurement of functioning in clinical practice should be systematic and comprehensive. However, different versions of the same functioning measure are used e.g. by physicians, psychologists, physiotherapists and occupational therapists. The TOIMIA network of experts aims to harmonize and develop the measuring of functioning in Finland.
Description of the problem
With increasing immigration to Finland, a specific need for guidelines on how to assess functional and work capacity of recently settled persons was identified. Led by the National Institute for Health and Welfare (mobiTARMO-project, 2017-2020), guidelines for assessing functional and work capacity in the integration phase are in preparation.
Results
The guidelines on assessing functional and work capacity in the integration phase include four principles: Functional and work capacity assessment should be done with culturally and linguistically appropriate methods.Assessment should be based on shared expertise of the professional and the client.Assessment should be comprehensive, and take into consideration physical, psychological, social and cognitive functional capacity, activities of daily living, and environmental factors.Assessment should be systematic and lead to further actions and necessary services.The national guidelines will be disseminated as free online access material in the Terveysportti health portal to professionals in clinical practice and research.
Lessons
There are specificities to the cross-cultural assessment of functional and work capacity of recently settled persons. National guidelines can be created through broad collaboration of different organizations, as in the TOIMIA network of experts in Finland.
Key messages
Jointly agreed principles on how to assess functional and work capacity in the integration phase benefit professionals and clients. National guidelines can be created, disseminated and taken into practice through broad collaboration.

Abstract
Abstract
Background
Sweden has contributed to the understanding of the long-term prognosis after myocardial infarction (MI) utilising the quality registry SWEDEHEART, including patients admitted to heart intensive care, and the National Patient Registry (PAR), based on administrative records for Swedish hospitals. As registration procedures differ between the registries, and not all MI patients are admitted to heart intensive care, MI patients identified in SWEDEHEART and PAR, respectively, will yield different cohorts of patients. This may result in different epidemiological research findings regarding prognosis after MI.
Purpose
To study MI populations identified in SWEDEHEART and PAR, respectively, and investigate potential differences in mortality outcome.
Methods
Patients hospitalised with an MI primary diagnosis (ICD-10 I21) between 2002 and 2015 were identified using SWEDEHEART and PAR. The analysis time started at the date of hospital admission and survivors were followed for 365 days. Kaplan-Meier analysis was used to estimate survival by cohort category controlling for age and gender.
Results
Excluding cases with invalid data (n=1,905), 225,612 and 282,118 SWEDEHEART and PAR patients, respectively, were identified. We found 213,367 patients in both SWEDEHEART and PAR, whereas 12,245 and 68,751 patients were unique to SWEDEHEART and PAR, respectively. The one-year survival probability after MI in the SWEDEHEART population was 0.841, compared to 0.788 in PAR (Figure). This discrepancy can be explained by high mortality among patients not covered by SWEDEHEART and persists after controlling for age and gender (Table). To what extent differences in registration procedures and other patient characteristics can explain the mortality difference is an area for further research.
One-year survival by age and gender Age ± 1 year Male Female PAR S.H. Diff. PAR S.H. Diff. 65 0.922 0.936 0.015 0.919 0.936 0.017 70 0.893 0.909 0.016 0.889 0.908 0.019 75 0.829 0.858 0.029 0.834 0.860 0.026 80 0.743 0.783 0.040 0.768 0.800 0.033 85 0.625 0.677 0.052 0.662 0.705 0.042
One-year survival after MI
Conclusion
Estimated one-year survival for MI patients differs by up to 5 percentage points depending on the registry used. Although further research is needed to fully understand these differences, epidemiological findings regarding MI prognosis should be interpreted in light of registry type used and population represented.

Abstract
Abstract
Background
Triple antithrombotic therapy (TAT) is known to increase bleeds and its relevance is questioned. No study has observed the long-term risk of bleeding and health care costs from a sex perspective, in a total TAT population. We investigated the rate of all bleeds in patients receiving TAT at index hospitalization and within one year. We explored early discontinuation of TAT and potential sex disparities. We also assessed health care costs related to bleeding complications.
Methods
All patients discharged with TAT registered in SWEDEHEART in the County of Östergötland 2009–2015 were included. Information about bleeds during one-year follow-up were retrieved from the medical records. All bleeds receiving medical attention were included. Resource use associated with bleeds were assigned unit cost to estimate the health care costs associated with bleeding episodes.
Results
Among 272 identified patients, 156 bleeds occurred post-discharge, of which 28.8% were gastrointestinal. In total 54.4% had at least one bleed during or after the index event and 40.1% bled post discharge of whom 28.7% experienced a TIMI major or minor bleeding. Women discontinued TAT prematurely more often than men (52.9 vs 36.1%, p=0.01) and bled more (48.6 vs. 37.1%, p=0.09). One-year mean health care costs were EUR 575 and EUR 5787 in non-bleeding and bleeding patients, respectively.
Conclusion
The very high bleeding incidence in patients with TAT is a cause of concern, especially in women. There is a need for an adequately sized randomized, controlled trial to determine a safe but still effective treatment for these patients.

Abstract
ObjectiveTo test if the Finnish Defence Forces Basic Intellectual Ability Test scores at 20.1 years predicted risk of organic dementia or Alzheimer disease (AD).MethodsDementia was defined as inpatient or outpatient diagnosis of organic dementia or AD risk derived from Hospital Discharge or Causes of Death Registers in 2,785 men from the Helsinki Birth Cohort Study, divided based on age at first diagnosis into early onset (<65 years) or late onset (≥65 years). The Finnish Defence Forces Basic Intellectual Ability Test comprises verbal, arithmetic, and visuospatial subtests and a total score (scores transformed into a mean of 100 and SD of 15). We used Cox proportional hazard models and adjusted for age at testing, childhood socioeconomic status, mother's age at delivery, parity, participant's birthweight, education, and stroke or coronary heart disease diagnosis.ResultsLower cognitive ability total and verbal ability (hazard ratio [HR] per 1 SD disadvantage >1.69, 95% confidence interval [CI] 1.01–2.63) scores predicted higher early-onset any dementia risk across the statistical models; arithmetic and visuospatial ability scores were similarly associated with early-onset any dementia risk, but these associations weakened after covariate adjustments (HR per 1 SD disadvantage >1.57, 95% CI 0.96–2.57). All associations were rendered nonsignificant when we adjusted for participant's education. Cognitive ability did not predict late-onset dementia risk.ConclusionThese findings reinforce previous suggestions that lower cognitive ability in early life is a risk factor for early-onset dementia.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVES To estimate total and cause-specific mortality after international peacekeeping deployments among the Finnish military peacekeeping personnel in comparison to the general population of similar age and sex. DESIGN A register-based study of a cohort of military peacekeeping personnel in 1990-2010 followed for mortality until the end of 2013. Causes of death were obtained from the national Causes of Death Register. The standardised mortality ratio (SMR) for total and cause-specific mortality was calculated as the ratio of observed and expected number of deaths. SETTING Finland (peacekeeping operations in different countries in Africa, Asia and in an area of former Yugoslavia in Europe). PARTICIPANTS 14 584 men and 418 women who had participated in international military peacekeeping operations ending between 1990 and 2010. INTERVENTIONS Participation in military peacekeeping operations. MAIN OUTCOME Total and cause-specific mortality. RESULTS 209 men and 3 women died after their peacekeeping service. The SMR for all-cause mortality was 0.55 (95% CI 0.48 to 0.62). For the male peacekeeping personnel, the SMR for all diseases was 0.44 (95% CI 0.35 to 0.53) and for accidental and violent deaths 0.69 (95% CI 0.57 to 0.82). The SMR for suicides was 0.71 (95% CI 0.53 to 0.92). CONCLUSIONS Even though military peacekeeping personnel are working in unique and often stressful conditions, their mortality after their service is lower compared with the general population. Military peacekeeping personnel appear to be a selected population group with low general mortality and no excess risk of any cause of death after peacekeeping service.

Abstract
BACKGROUND We evaluated the body composition and its association with hypogonadism in adult male long-term acute lymphoblastic leukemia (ALL) survivors. METHODS The cohort included 49 long-term male ALL survivors and 55 age-matched healthy controls. Fat and lean mass was assessed by dual-energy X-ray absorptiometry; blood biochemistry was obtained for adipokines and testicular endocrine markers. RESULTS As compared with controls, the ALL survivors (median age 29 years, range 25-38), assessed 10-28 years after ALL diagnosis, had higher percentages of body (p < 0.05) and trunk fat mass (p < 0.05), and a lower body lean mass (p < 0.001). Survivors had significantly higher levels of leptin and adiponectin and lower levels of insulin-like growth factor-binding protein 3. Body fat mass and percent fat mass correlated with serum leptin and sex hormone-binding globulin (SHBG) levels. Altogether, 15% of the ALL survivors and 9% of age-matched controls were obese (BMI ≥ 30). Obese survivors more often had hypogonadism, had received testicular irradiation, and needed testosterone replacement therapy compared to nonobese survivors. CONCLUSION At young adulthood, long-term male ALL survivors have significantly increased body adiposity despite normal weight and BMI. Potential indicators of increased adiposity included high leptin and low SHBG levels. Serum testicular endocrine markers did not correlate with body adiposity.

Abstract
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.

Abstract
The updated Current Care Guidelines for ASD and PTSD recommend psychosocial support and careful monitoring for acute stress reaction (ASR) and acute stress disorder (ASD). If symptoms require, short focused cognitive-behavioral psychotherapy can be used for ASD. Medication is rarely necessary. Trauma-focused psychotherapeutic interventions are the first-line treatment for post-traumatic stress disorder (PTSD). Antidepressant medication is an effective second-line treatment. Psychotherapeutic interventions and medication should often be combined. Specific groups, such as children, the elderly, and military and peacekeeping personnel need tailored interventions.

Abstract
Objective To investigate the cost effectiveness of ticagrelor versus clopidogrel in patients with acute coronary syndromes (ACS) in the Platelet Inhibition and Patient Outcomes (PLATO) study who were scheduled for non-invasive management. Methods A previously developed cost effectiveness model was used to estimate long-term costs and outcomes for patients scheduled for non-invasive management. Healthcare costs, event rates and health-related quality of life under treatment with either ticagrelor or clopidogrel over 12 months were estimated from the PLATO study. Long-term costs and health outcomes were estimated based on data from PLATO and published literature sources. To investigate the importance of different healthcare cost structures and life expectancy for the results, the analysis was carried out from the perspectives of the Swedish, UK, German and Brazilian public healthcare systems. Results Ticagrelor was associated with lifetime quality-adjusted life-year (QALY) gains of 0.17 in Sweden, 0.16 in the UK, 0.17 in Germany and 0.13 in Brazil compared with generic clopidogrel, with increased healthcare costs of €467, €551, €739 and €574, respectively. The cost per QALY gained with ticagrelor was €2747, €3395, €4419 and €4471 from a Swedish, UK, German and Brazilian public healthcare system perspective, respectively. Probabilistic sensitivity analyses indicated that the cost per QALY gained with ticagrelor was below conventional threshold values of cost effectiveness with a high probability. Conclusions Treatment of patients with ACS scheduled for 12 months’ non-invasive management with ticagrelor is associated with a cost per QALY gained below conventional threshold values of cost effectiveness compared with generic clopidogrel. Trial registration number NCT000391872.

Abstract
BACKGROUND Suicide mortality in Finland particularly among young people remains high, compared with other European countries. Suicide is one of the leading causes of death among military conscripts in Finland. AIMS In this record-based study, we investigated characteristics of all 48 suicides among Finnish conscripts during the period 1991-2007. METHODS We collected and analyzed healthcare records during military service and medicolegal investigations (medicolegal autopsy) of suicide victims. RESULTS Of the 48 suicides, 36 (75%) were completed during leave days. Shooting, hanging and jumping were the most common methods used; a service gun was used in four (14%) of the 29 shooting cases. One-third of the victims had been in contact with military healthcare during the week preceding their suicide, and two-thirds during the preceding month. CONCLUSIONS When conscripts use healthcare services, suicidal thoughts should be actively asked of those conscripts with history of any risk factors for suicidal behavior.

Abstract
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.

Abstract
OBJECTIVES/HYPOTHESIS Otorhinolaryngology (ORL) is considered a specialty associated with few serious patient injuries. Research data that support this belief are, however, scarce. We analyzed claims associated with ORL to determine the number of Finnish cases and the possible common denominators. STUDY DESIGN Register study of ORL cases in the Patient Insurance Centre (PIC), the Regional State Administrative Agencies (RSAA), and the National Supervisory Authority for Welfare and Care (Valvira) during the years 2004 to 2008. METHODS These three agencies are the main actors in the field of patient injury in Finland. We analyzed compensated ORL patient injury cases from the PIC and cases associated with the ORL specialty for Valvira and RSAA from 2004 to 2008 and surveyed patient treatment files, statements from specialists, and compensation decisions. RESULTS Injuries were usually associated with operations; three patients who experienced injuries during these procedures died. Common ORL operations such as tonsillectomy, septoplasty, and paranasal sinus surgery were most often associated with compensated injuries. Serious injuries were few, with a total of 110 out of 422 (26.1%) claims compensated by the PIC. Of the 110 compensated cases, 30 (27.3%) were related to tumor surgery. The most usual compensated case had iatrogenic nerve injury affecting the facial or trigeminal nerves. Of the compensated cases, 79 (71.8%) were treated by specialists, 15 (13.6%) by residents, and the rest by other medical professionals. CONCLUSIONS Patient injuries in ORL are seldom severe and are strongly associated with surgery. A typical compensated injury was one that occurred in a central hospital during working hours.

Abstract
OBJECTIVE Long-term health sequelae of childhood-onset acute lymphoblastic leukemia (ALL) remain largely unknown. Low bone mineral content (BMC) and bone mineral density (BMD) are recognized complications, but it is unknown whether these persist until adulthood. We evaluated skeletal characteristics and their association with ALL therapy in long-term male ALL survivors. DESIGN This cross-sectional cohort study included 49 long-term male ALL survivors and 55 age-matched healthy males. METHODS BMD and compression fractures were assessed by dual-energy X-ray absorptiometry; blood biochemistry was obtained for parameters of calcium homeostasis. RESULTS The ALL survivors (median age 29 years, range 25-38 years), assessed 10-38 years after ALL diagnosis, had lower lumbar spine (P<0.001), femoral neck (P<0.001), and whole-body (P=0.017) BMD than expected based on normative values. When compared with the controls (median age 30 years, range 24-36 years), the ALL survivors had lower lumbar spine BMC (P=0.014), lower whole-body BMC (P<0.001), and lower whole-body BMD (P<0.001), but the differences were partly explained by differences in height. Altogether, 20% of the ALL survivors had spinal compression fractures, but these were equally prevalent in the controls. Males diagnosed with ALL before age 5 years had significantly lower BMD values. Other recognized risk factors included untreated hypogonadism, vitamin D deficiency, hypophosphatemia, low IGF-binding protein-3, and low physical activity. CONCLUSIONS At young adulthood, long-term male ALL survivors have significantly reduced BMC and BMD and a high prevalence of spinal compression fractures. Careful follow-up and active treatment of the recognized risk factors are warranted.

Abstract
OBJECTIVES To examine whether the adverse effects of slow prenatal and postnatal growth on cognitive function persist to old age and predict age related cognitive decline. DESIGN AND SETTING A longitudinal birth cohort study of men born in Helsinki, Finland 1934-44. PARTICIPANTS Nine-hundred-thirty-one men of the Helsinki Birth Cohort Study, with detailed data on growth from birth to adulthood, aged 20.1 (SD = 1.4) at the first and 67.9 (SD = 2.5) years at the second cognitive testing. MAIN OUTCOME MEASURES The Finnish Defense Forces Basic Intellectual Ability Test assessed twice over nearly five decades apart. RESULTS Lower weight, length and head circumference at birth were associated with lower cognitive ability at 67.9 years (1.04-1.55 points lower ability per each standard deviation [SD] unit decrease in body size, 95% Confidence Interval [95%CI]: 0.05 to 2.72) and with cognitive decline after 20.1 years (0.07-0.11 SD decline over time per each SD decrease in body size, 95%CI:0.00 to 0.19). Men who were born larger were more likely to perform better in the cognitive ability test over time (1.22-1.43 increase in odds to remain in the top relative to the lower two thirds in ability over time per each SD increase in body size, 95%CI:1.04 to 1.79) and were more resilient to cognitive decline after 20.1 years (0.69 to 0.76 decrease in odds to decline from than remain in the top third of ability over time per each SD increase in body size, 95%CI:0.49 to 0.99). Slower growth between birth and two years in weight, height and body mass index was associated with lower cognitive ability at 67.9 years, but not with cognitive decline. CONCLUSIONS Poorer lifetime cognitive ability is predicted by slower growth before and after birth. In predicting resilience to age related cognitive decline, the period before birth seems to be more critical.

Abstract
We examined the effects of early life stress on cognitive ability and decline among men of the Helsinki Birth Cohort Study, 10% of whom were separated temporarily (mean age at separation = 4.1 years) from their parent(s) during World War II. The men underwent the Finnish Defense Forces Basic Intellectual Ability Test twice, at 20 years and retest at 70 years. Compared with the men without childhood separation and matched for year of birth (n = 186), men separated from their parents (n = 93) scored lower by 5.5 (95% confidence interval [CI], -9.2 to -1.7), 4.2 (95% CI, -8.1 to -0.3), 3.1 (95% CI, -7.0 to 0.8), and 4.5 (95% CI, -10.5 to -1.4) standardized points (SD = 15) on verbal, visuospatial, arithmetic, and general cognitive ability, respectively, at 70 years. Longer duration of separation was associated with lower test scores. Though early life stress was also associated significantly with weaker cognitive performance at the ages 20 and 70 years, it was not associated with cognitive decline over the 50-year period within this sample.

Abstract
Background Low intellectual ability is associated with an increased risk of coronary heart disease and stroke. Most studies have used a general intelligence score. We studied whether three different subscores of intellectual ability predict these disorders. Methods We studied 2,786 men, born between 1934 and 1944 in Helsinki, Finland, who as conscripts at age 20 underwent an intellectual ability test comprising verbal, visuospatial (analogous to Raven's progressive matrices) and arithmetic reasoning subtests. We ascertained the later occurrence of coronary heart disease and stroke from validated national hospital discharge and death registers. Results 281 men (10.1%) had experienced a coronary heart disease event and 131 (4.7%) a stroke event. Coronary heart disease was predicted by low scores in all subtests, hazard ratios for each standard deviation (SD) lower score ranging from 1.21 to 1.30 (confidence intervals 1.08 to 1.46). Stroke was predicted by a low visuospatial reasoning score, the corresponding hazard ratio being 1.23 (95% confidence interval 1.04 to 1.46), adjusted for year and age at testing. Adjusted in addition for the two other scores, the hazard ratio was 1.40 (1.10 to 1.79). This hazard ratio was little affected by adjustment for socioeconomic status in childhood and adult life, whereas the same adjustments attenuated the associations between intellectual ability and coronary heart disease. The associations with stroke were also unchanged when adjusted for systolic blood pressure at 20 years and reimbursement for adult antihypertensive medication. Conclusions Stroke is predicted by low visuospatial reasoning scores in relation to scores in the two other subtests. This association may be mediated by common underlying causes such as impaired brain development, rather than by mechanisms associated with risk factors shared by stroke and coronary heart disease, such as socio-economic status, hypertension and atherosclerosis.

Abstract
OBJECTIVE We tested whether maternal hypertensive disorders in pregnancy predict age-related change in cognitive ability in the offspring up to old age. METHODS Using mothers' blood pressure and urinary protein measurements from the maternity clinics and birth hospitals, we defined normotensive or hypertensive pregnancies in mothers of 398 men, who participated in the Helsinki Birth Cohort 1934-1944 Study. The men underwent the Finnish Defence Forces basic ability test twice: first during compulsory military service at age 20.1 (SD = 1.4) years and then in a retest at age 68.5 (SD = 2.9) years. The test yields a total score and subscores for tests measuring verbal, arithmetic, and visuospatial reasoning. RESULTS Men born after pregnancies complicated by a hypertensive disorder, compared with men born after normotensive pregnancies, scored 4.36 (95% confidence interval, 1.17-7.55) points lower on total cognitive ability at 68.5 years and displayed a greater decline in total cognitive ability (2.88; 95% confidence interval, 0.07-5.06) after 20.1 years. Of the subscores, associations were strongest for arithmetic reasoning. CONCLUSION Maternal hypertensive disorders in pregnancy predict lower cognitive ability and greater cognitive decline up to old age. A propensity to lower cognitive ability and decline up to old age may have prenatal origins.

Abstract
We have investigated the guiding and triggering of discharges from a Tesla coil type 280 kHz AC high voltage source using filaments created by a femtosecond Terawatt laser pulse. Without the laser the discharges were maximum 30 cm long. With the laser straight, guided discharges up to 110 cm length were detected. The discharge length was limited by the voltage amplitude of the Tesla coil.

Abstract
AIM Experimental cerebral ischaemia and organ culture of cerebral arteries induce an increased endothelin ET(B) receptor-mediated contraction. The aim of this study was to examine whether cytokines and growth factors, known to be activated in ischaemia, can influence the expression and function of endothelin receptors after organ culture. METHODS Rat middle cerebral arteries were cultured for 24 h at 37 °C in humidified 5% CO(2) and air in culture medium alone, or with tumour necrosis factor-α (TNF-α), interleukin-1β (IL-1β), platelet-derived growth factor (PDGF), epidermal growth factor (EGF) or basic fibroblast growth factor (bFGF). Concentration-response curves were obtained for sarafotoxin 6c (ET(B) receptor agonist) and endothelin-1 (here ET(A) receptor agonist, because of ET(B) receptor desensitization). The receptor mRNA expression was examined by real-time PCR and the protein expression by immunohistochemistry and Western blot. RESULTS Tumour necrosis factor-α (100 ng mL(-1) ) and EGF (20 ng mL(-1) ) potentiated the ET(B) receptor-mediated contraction (increase in pEC(50) without change in E(max) ). bFGF (10 ng mL(-1) ) and IL-1β (10 ng mL(-1) ) induced an enhanced ET(A) receptor-mediated contraction. bFGF (10 ng mL(-1) ) significantly increased the ET(B) mRNA level, and EGF (20 ng mL(-1) ) increased the ET(A) receptor protein. Increased ET(B) receptor mRNA and protein level also were observed after treatment with IL-1β (10 ng mL(-1) ). CONCLUSION This study shows that TNF-α, IL-1β, EGF and bFGF can modify the expression and function of endothelin receptors during organ culture. Because there is similar receptor upregulation in experimental stroke, the effect of cytokines and growth factors on endothelin receptor upregulation is an interesting aspect to study in vivo.

Abstract
BACKGROUND Hypertensive disorders may affect the fetal developmental milieu and thus hint at mechanisms by which prenatal adversity associates with poorer intellectual ability in subsequent life. AIM We tested if hypertensive disorders in pregnancy are associated with intellectual ability in the offspring in young adulthood and if any potential associations between hypertensive disorders and intellectual abilities differ according to length of gestation, birth-weight, parity, and childhood socio-economic background. METHODS Using mothers' blood pressure and urinary protein measurements at maternity clinics and birth hospitals, we defined normotensive or hypertensive pregnancies in mothers of 1,196 men who participated in the Helsinki Birth Cohort 1934-1944 Study. At age 20 years the men completed a test on intellectual abilities during compulsory military service. RESULTS Participants born after pregnancies complicated by hypertensive disorders scored lower on intellectual abilities compared to those born after normotensive pregnancies. The effects of hypertensive disorders were most obvious in men born preterm or after a primiparous pregnancy and in men of higher childhood socio-economic background. CONCLUSION Hypertensive disorders in pregnancy are, albeit weakly, associated with lower intellectual abilities in the offspring. These findings are compatible with the concept of adverse fetal 'programming' by a suboptimal prenatal environment.

Abstract
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.

Abstract
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.

Abstract
AIMS The aim of this study was to identify factors associated with suicidal ideation among young men exempted from compulsory military or civil service in Finland. METHODS The study involved a total of 356 men exempted from military or civil service. The research data were collected using questionnaires and register data. RESULTS One third of the young men exempted from compulsory military or civil service reported serious suicidal ideation. Of the men with serious suicidal ideation, one third had attempted suicide. Various childhood adversities and current stressful life events and problems were associated with suicidal ideation. Multivariate logistic regression analysis showed that the following factors were independently associated with suicidal ideation: maternal alcohol-related problems, changes in the family, discord with the boss over the past 12 months, and lack of social support. Accumulation of problems predicted suicidal ideation. CONCLUSIONS Men exempted from compulsory military or civil service comprise an important target group in the prevention of suicide. In order to prevent suicidal behaviour among young men at risk, it is important to address the significance of social support and relationships, and likewise to be aware of early risk indicators such as maternal alcohol-related problems.
