Age-related incidence of cervical cancer supports two aetiological components: a population-based register study.

OBJECTIVE: To assess whether age-related incidence of cervical cancer supports two aetiological components and to assess trends in these components due to risk factors and to organised screening in Finland. DESIGN: Population-based register study. SETTING: Finnish Cancer Registry. POPULATION: Cervical cancer cases and female population in Finland in 1953-2012. METHODS: Cervical cancer incidence was estimated using Poisson regression where age-specific incidence consists of two (early-age and late-age) normally distributed components. MAIN OUTCOME MEASURES: Accumulated net risks (incidences) and numbers of cancer cases attributed to each age-related component by calendar time. RESULTS: The accumulated cervical cancer incidence in 2008-2012 was only 30% of that in 1953-1962, before the screening started. The fit of the observed age-specific rates and the rates based on the two-component model was good. In 1953-62, the accumulated net risk ratio (RR; early-age versus late-age) was 0.42 (95% CI 0.29-0.61). The early-age component disappeared in 1973-77 (RR 0.00; 95% CI 0.00-0.08). Thereafter, the risk for the early-age component increased, whereas the risk for the late-age component decreased, and in 2008-2012 the RR was 0.55 (95% CI 0.24-0.89). CONCLUSIONS: In Finland, cervical cancer incidence has two age-related components which are likely to indicate differences in risk factors of each component. The trend in risk of both components followed the effects of organised screening. Furthermore, the risk related to the early-age component followed changes in risk factors, such as oncogenic HPV infections and other sexually transmitted diseases and smoking habits. TWEETABLE ABSTRACT: Cervical cancer incidence has two age-related components which are likely to have differencies in their aetiology.

Effectiveness of screening for colorectal cancer with a faecal occult-blood test, in Finland.

BACKGROUND: Screening for colorectal cancer (CRC) with guaiac-based faecal occult-blood test (FOBT) has been reported to reduce CRC mortality in randomised trials in the 1990s, but not in routine screening, so far. In Finland, a large randomised study on biennial FOB screening for CRC was gradually nested as part of the routine health services from 2004. We evaluate the effectiveness of screening as a public health policy in the largest population so far reported. METHODS: We randomly allocated (1:1) men and women aged 60-69 years to those invited for screening and those not invited (controls), between 2004 and 2012. This resulted in 180 210 subjects in the screening arm and 180 282 in the control arm. In 2012, the programme covered 43% of the target age population in Finland. RESULTS: The median follow-up time was 4.5 years (maximum 8.3 years), with a total of 1.6 million person-years. The CRC incidence rate ratio between the screening and control arm was 1.11 (95% CI 1.01 to 1.23). The mortality rate ratio from CRC between the screening and control arm was 1.04 (0.84 to 1.28), respectively. The CRC mortality risk ratio was 0.88 (0.66 to 1.16) and 1.33 (0.94 to 1.87) in males and females, respectively. CONCLUSIONS: We did not find any effect in a randomised health services study of FOBT screening on CRC mortality. The substantial effect difference between males and females is inconsistent with the evidence from randomised clinical trials and with the recommendations of several international organisations. Even if our findings are still inconclusive, they highlight the importance of randomised evaluation when new health policies are implemented. TRIAL REGISTRATION: 002_2010_august.

Avoidable deaths and random variation in patients' survival.

BACKGROUND: Random error in the numbers of avoidable deaths among cancer patients has not been considered in earlier studies. METHODS: Methods to obtain valid confidence intervals (CIs) for numbers of avoidable deaths were developed. The excess mortality rates were estimated for patients diagnosed with colon cancer in five cancer control regions in Finland during 2000-2007 using a relative survival regression model. Numbers of avoidable deaths due to colon cancer and other causes, respectively, were estimated in different scenarios. RESULTS: Altogether, 4139 and 1335 out of 10 772 patients under 90 years at diagnosis were estimated to have died due to colon cancer and other causes, respectively, during the first 5 years after diagnosis. If all the patients had shared the relative survival of the largest cancer control region to which the country capital belongs, the estimated number of avoidable deaths would have been 146 (95% CI 3-290). CONCLUSION: Random error in numbers of avoidable deaths, often substantial, can be quantified by realistic error margins, based on appropriate statistical methods.

Education, survival and avoidable deaths in cancer patients in Finland.

BACKGROUND: Relative survival after cancer in Finland is at the highest level observed in Europe and has, in general, been on a steady increase. The aim of this study is to assess whether the high survival is equally shared by different population subgroups and to estimate the possible gains that might be achieved if equity prevailed. MATERIALS AND METHOD: The educational level and occupation before the cancer diagnosis of patients diagnosed in Finland in 1971-2005 was derived from an antecedent population census. The cancers were divided into 27 site categories. Cancer (cause)-specific 5-year survival proportions were calculated for three patient categories based on the educational level and for an occupational group of potentially health-conscious patients (physicians, nurses, teachers etc.). Proportions of avoidable deaths were derived by assuming that the patients from the two lower education categories would have the same mortality owing to cancer, as those from the highest educational category. Estimates were also made by additionally assuming that even the mortalities owing to other causes of death were all equal to those in the highest category. RESULTS: For almost all the sites considered, survival was consistently highest for patients with the highest education and lowest for those with only basic education. The potentially health-conscious patients had an even higher survival. The differences were, in part, attributable to less favourable distributions of tumour stages in the lower education categories. In 1996-2005, 4-7% of the deaths in Finnish cancer patients could have potentially been avoided during the first 5-year period after diagnosis, if all the patients had the same cancer mortality as the patients with the highest educational background. The proportion would have also been much higher, 8-11%, if, in addition, the mortality from other causes had been the same as that in the highest educational category. INTERPRETATION: Even in a potentially equitable society with high health care standards, marked inequalities persist in cancer survival. Earlier cancer diagnosis and the ability to cope within the health care system may be a partly relevant explanation, but personal habits and lifestyles also have a role, particularly for the cancer patients' mortality from other causes of death than cancer.

Matrix metalloproteinase-9 is elevated in serum of alcohol abusers.

BACKGROUND: Moderate alcohol consumption has been shown to protect against coronary heart disease. However, excessive alcohol use has been suggested to have detrimental effects on the cardiovascular system. We examined whether there is an association between alcohol abuse and circulating levels of matrix metalloproteinase-9 (MMP-9), which has been linked to unstable coronary heart disease and arterial inflammation. DESIGN: Serum MMP-9 concentrations were compared between 40 male alcoholics (mean age 42 years) with ethanol consumption > 1000 g week(-1) and 40 social drinker males with an ethanol consumption of < 200 g week(-1) (mean age 45 years). RESULTS: The mean serum MMP-9 concentration was significantly higher in sera of alcoholics compared to control subjects (70.9 +/- 47.7 g L(-1) and 43.1 +/- 19.2 g L(-1), respectively; P = 0.001). Within the alcoholic group, MMP-9 concentration did not correlate with age, gamma glutamyl transferase, carbohydrate-deficient transferrin, aspartate aminotransferase, alanine aminotransferase or alkaline phosphatase. CONCLUSION: Our finding of elevated MMP-9 concentrations in sera of chronic alcohol abusers helps understand the mechanisms of cardiovascular risk among these subjects.

Tratamiento y evaluación de los conductores que conducen bajo el efecto del alcohol enFinlandia / Treatment and assessment of drunken drivers in Finland

Objetivo: los esfuerzos previos para el tratamiento de los conductores que conducen bajo los efectos de alcohol (CBEA) han fracasado en Finlandia. Hoy en día, basado en la directriz de la UE, el conductor que conduce bajo el efecto del alcohol frecuentemente requiere un certificado médico referente a su capacidad para conducir un vehículo en relación a su adicción a las drogas antes de recuperar su carnet de conducir. Se consideró esto último como una posibilidad a nivel nacional para reducir la conducción bajo el efecto del alcohol y también reducir el abuso de sustancias adictivas. Con el apoyo del Ministerio de Bienestar Social y Salud, hemos empezado la colaboración con la policía, la atención primaria, el Hospital Universitario, y la Clínica-A en la cuidad de Tampere. Material y métodos: todos los conductores que conducen bajo el efecto del alcohol (concentración de alcohol en sangre >=0,05 por ciento), y que son detenidos por la policía dos veces durante los tres últimos años o una vez si tienen su primer carnet de conducir, que es válido durante dos años (suelen ser conductores jóvenes) o si conducen bajo el efecto de drogas, la policía les enviará para que sean evaluados. Todos necesitan un certificado médico sobre su adicción para recuperar su carnet de conducir después de cumplir la pena. Resultados: la evaluación y el tratamiento de los conductores que conduzcan bajo los efectos del alcohol incluyen 6-7 visitas y la duración del tratamiento y la evaluación se ajusta con la duración de la pena (aproximadamente 6-7 meses). Hasta la fecha, 255 conductores ebrios, el 80 por ciento de los remitidos por la policía, se han puesto en contacto para su evaluación en Tampere. Las primeras experiencias han sido positivas. Conclusiones: El futuro demostrará si la reincidencia de CBEA y los accidentes de tráfico disminuirán como consecuencia del tratamiento (conocimiento, motivación, habilidad, tratamiento individual y en grupo) (AU)

At which drinking level to advise a patient? General practitioners' views.

This study examined the views of 64 general practitioners (GPs) on how much a patient has to drink to be advised by them and compared the results to the recommended Finnish threshold values of heavy drinking. The levels stated by GPs were not too high to prevent early-phase intervention in heavy drinking; rather, they were so low that numerous moderate drinkers were also included. The mean (SD) level was 15.5 (6.5) drinks for male and 11.0 (4.6) drinks for female patients per week. These are about two-thirds of the Finnish threshold values of heavy drinking. Attempting to advise such high proportions of patients, including both heavy and moderate drinkers, might mean a discouraging burden for GPs. However, there may be a discrepancy between GPs' statements about when to advise and when they actually do so.

Brief intervention for male heavy drinkers in routine general practice: a three-year randomized controlled study.

The aim of this research was to evaluate the effectiveness of long-term brief intervention in routine general practice. In five primary care out-patient clinics in a Finnish town, 296 male early-phase heavy drinkers consulting a general practitioner (GP) for various reasons were identified. Control group C (n = 88) was informed of the risks of drinking after the screening and were advised at the subsequent feedback about 2 weeks later to reduce their drinking. Groups A (n = 109) and B (n = 99) were offered in addition seven and three brief intervention sessions, respectively. All GPs took part, whether or not they indicated a special interest. The main outcome measures were differences between beginning and end-point at 3 years in self-reported alcohol consumption, mean corpuscular volume (MCV), and serum carbohydrate-deficient transferrin, aspartate aminotransferase, alanine aminotransferase and gamma-glutamyltransferase. There were no statistically significant differences between study groups A, B and C in mean changes in outcome measures. Within all the groups, MCV decreased. Depending on the outcome measure used and the study group analysed, clinically significant reduction of drinking was found in 25-53% of the subjects. In routine general practice, giving additional sessions of brief intervention may not be as effective as in special research conditions. Factors reducing the effectiveness of brief intervention programmes should be investigated, so that primary health care staff can be better supported in their efforts.

Opinions on alcohol-related issues among professionals in primary, occupational, and specialized health care.

The objective of this study was to analyse differences in health care personnel's knowledge, skills, and attitudes in relation to alcohol-related matters by a postal questionnaire between primary, occupational, and specialized health care. Heavy drinking was considered to be common among patients at all health care levels, and particularly in specialized health care. However, early recognition and treatment of heavy drinkers was considered more appropriate in primary and occupational health care, than in specialized health care. Alcohol consumption was found to be an easy subject to discuss at all health care levels. In addition, 90% (165/183) of the respondents thought that patients had a positive or neutral attitude towards questions on their alcohol consumption. Of the respondents, 32% (58/182) considered discussing alcohol-related matters unacceptable and 81% (121/149) believed that they could not influence patients' drinking using brief intervention; there was no significant difference between different settings. Additionally, motivational skills of doctors and nurses were found to be poor at all health care levels. Our study shows that, although discussing alcohol consumption is easy, better motivational skills and more positive attitudes are needed in primary, occupational, and specialized health care. Professionals need further education at all health care levels, but particularly in specialized health care.

Primary health care nurses' and physicians' attitudes, knowledge and beliefs regarding brief intervention for heavy drinkers.

AIMS: To identify barriers to healthcare providers carrying out competent brief interventions to help heavy drinkers to reduce their drinking. DESIGN AND PARTICIPANTS: A questionnaire on attitudes, skills, knowledge, training needs and suggestions for implementation of brief interventions was mailed to all nurses and physicians working in primary health care in two Finnish cities. One hundred and sixty-seven primary health care nurses and 84 physicians returned the questionnaire. FINDINGS AND CONCLUSIONS: The response rates among nurses varied between 66 and 99% and among physicians between 76 and 95% depending on the issue. Factors related to knowledge seem to be a barrier to the adoption of brief intervention: only 18% of respondents reported having enough knowledge to provide competent brief intervention and half of the respondents reported wanting more training. Contrary to expectations, physicians consider themselves to be better equipped to do brief intervention than nurses. Practical training in using alcohol questionnaires and on the content of brief intervention would help promote it. Such training was seen as important by 90% of the respondents. Giving more information on the evidence in favour of brief intervention would also be useful.

Brief intervention for female heavy drinkers in routine general practice: a 3-year randomized, controlled study.

BACKGROUND: Today, heavy drinking is a common health hazard among women. The evidence in favor of providing some kind of brief intervention to reduce drinking is quite convincing. However, we do not know if intervention works in a natural environment of routine health care. The purpose of this study was to evaluate the effectiveness of long-lasting, brief alcohol intervention counseling for women in a routine general practice setting. METHODS: In five primary care outpatient clinics in a Finnish town, 118 female early-phase heavy drinkers who consulted their general practitioners for various reasons were given brief alcohol intervention counseling. Intervention groups A (n = 40) and B (n = 38) were offered seven and three brief intervention sessions, respectively, over a 3-yr period. The control group C (n = 40) was advised to reduce drinking at baseline. Main outcome measures were self-reported weekly alcohol consumption, carbohydrate-deficient transferrin, mean corpuscular volume (MCV), aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyltransferase. RESULTS: Depending on the outcome measure and the study group, clinically meaningful reduction of drinking was found in 27% to 75% of the heavy drinkers. Within all the groups, MCV significantly decreased. However, there were no statistically significant differences between study groups A, B, and C in the mean changes between the beginning and endpoint in the main outcome measures. CONCLUSIONS: The present study indicated that minimal advice, as offered to group C, was associated with reduced drinking as much as the brief intervention, as offered to groups A and B, given over a 3-yr period. Furthermore, in the routine setting of the general practice office, the effectiveness of the brief intervention may not be as good as in special research conditions. The factors possibly reducing the effectiveness in a routine setting are unknown. Thus, different methods of implementing brief intervention need to be evaluated to find better ways to support general practice personnel in their efforts to help heavy-drinking female patients to reduce their drinking.

Alcohol consumption and its relation to lipid-based cardiovascular risk factors among middle-aged women: the role of HDL(3) cholesterol.

To study the association of alcohol consumption and lipid-based cardiovascular risk factors among middle-age women, cross-sectional analysis among 274 middle-aged healthy women with different drinking habits and a follow-up analysis of alcoholic women during abstinence was performed. Serum total cholesterol, low and high-density lipoprotein cholesterol (LDL and HDL cholesterol), triglycerides (TG), apolipoproteins A1 (Apo A1) and B (Apo B), and HDL-cholesterol subfractions 2 (HDL(2)) and 3 (HDL(3)) were measured. All lipid values except LDL cholesterol positively correlated with self-reported alcohol consumption. When alcoholics were excluded the correlation was significant only for HDL cholesterol, HDL(3), and Apo A1. The increasing trend of HDL cholesterol, HDL(3) and Apo A1 were clearly seen first in women consuming >20-40 g/day of absolute alcohol. Alcohol consumption >40 g/day increased all lipid values except LDL cholesterol. Abstinence for 2 weeks caused a significant decrease in HDL(3) cholesterol, and an increase in LDL cholesterol and Apo B. The results indicate that among middle-aged women the Apo A1 and HDL cholesterol via its HDL(3) but not HDL(2) subfraction might play a role in the beneficial coronary consequences associated with moderate alcohol consumption. However, the increasing beneficial trend first appears when daily drinking exceeds 20 g/day.

Persistence of substance use-related hospital utilization among psychiatric consultation patients.

Among 86 consecutive consultation-liaison (C-L) patients with current substance use-related hospital attendance, the case records revealed an average history of 5.9 years in male patients and 5.3 years in female patients of repeated substance use-related hospital visits. A history of at least 1 year was found in 60% (52/86) of patients. The history had started at the age of early 30s with attempted suicide as the most common principal diagnosis. By the age of 40, there had been several hospital visits for various health problems. However, 48% (41/86) of the patients had never received substance use treatment. It appeared that opportunities to intervene with substance use were frequently missed on hospital encounters, a finding also observed in earlier studies.

Sialic acid: new potential marker of alcohol abuse.

BACKGROUND: A number of laboratory markers are suggested for the detection and monitoring of alcohol abuse. However, there is still a need to find better indicators of alcohol abuse. Sialic acid (SA) is the name for a series of acyl-derivatives of neuraminic acids that occur as nonreducing terminal residues of glycoproteins or glycolipids in biological fluids and cell membranes. In this study, we investigated the diagnostic value of SA as a marker of alcohol abuse. METHODS: Sera from social drinkers (n = 38) and alcoholics (n = 77) were analyzed for sialic acid by a colorimetric assay and for carbohydrate-deficient transferrin (CDT) by a radioimmunoassay method. Mean corpuscular volume (MCV), gamma-glutamyltransferase (GGT), aspartate aminotransferase (ASAT), and alanine aminotransferase (ALAT) were determined by using routine methods. RESULTS: The sialic acid levels of both female and male subjects were significantly (p < 0.001) increased among alcoholic subjects when compared with social drinkers. SA levels were decreased after 3 weeks of treatment. The sensitivity and specificity for SA, respectively, were 57.7 and 95.5 for women and 47.8 and 81.3 for men. The respective values for CDT were 57.7 and 95.5 for women and 78.3 and 100.0 for men; for GGT, 60.0 and 95.5 for women and 60.9 and 87.5 for men; for MCV, 52.4 and 95.5 for women and 47.8 and 100.0 for men; for ASAT, 53.8 and 95.5 for women and 43.5 and 100.0 for men; and for ALAT, 38.5 and 90.9 for women and 39.1 and 87.5 for men. Among women, SA and GGT, and among men CDT, showed the largest area under receiver operation curve. CONCLUSION: This study indicated that sialic acid levels were elevated by high alcohol consumption and reduced during abstinence, especially among women. Thus, sialic acid seems to be an interesting marker that needs further evaluation as a diagnostic tool for alcohol abuse.

Alcohol consumption profile by time in middle-aged men: a longitudinal study based on three different diagnostic instruments.

This longitudinal study aimed at comparing aggregate measures of heavy or problem drinking and their variations across time among the same subjects. We examined middle-aged men participating in a health survey over a 5-year interval. Of the 133 consecutive men in the whole age group interviewed as 40-year-olds in 1989, 114 were reached and re-interviewed in 1994. Alcohol consumption was measured by self-report, Malmo-modified Michigan Alcoholism Screening Test (Mm-MAST), and serum carbohydrate-deficient transferrin (CDT). Self-reported alcohol consumption decreased with years (142 vs 105 g/week, P = 0.01), as did CDT (16.9 vs 14.4 U/l, P = 0.02), but there was no change in the Mm-MAST results. There was no significant difference in the number of heavy drinkers (either Mm-MAST score > or = 3, or by self-reported alcohol consumption > or = 280 g/week, or by CDT > or = 20 U/l) at 40 and 45 years of age (37 and 47% respectively). At the individual level, alcohol consumption both increased and decreased with age. At 45 years of age 5/114 (4%) of the men reported that they had increased their alcohol consumption by more than 80 g/week and 25/114 (22%) said that they had reduced their drinking by the same amount. The remaining 84 (74%) reported drinking the same amount as 5 years earlier (+/- 80 g/week). This indicates that alcohol drinking habits are not stable in middle age. Most heavy drinkers in both age groups were detected by Mm-MAST and this proportion increased with age while the proportion of positive self-reports and CDTs decreased. Thus, the social consequences, measured here by the Mm-MAST, may be more readily experienced with years even at smaller consumption levels.

Patterns of comorbidity in relation to functioning (GAF) among general hospital psychiatric referrals. European Consultation-Liaison Workgroup.

Improvement of services for physically ill patients with concurrent psychiatric problems is a noteworthy issue in general hospitals. Among 1249 general hospital in-patients referred for psychiatric consultation, concurrent mental and behavioural disorders (ICD-10) were diagnosed in 84% of cases. Any concurrent mental and behavioural disorder was associated with dramatically low functioning (GAF = 46), indicating serious psychosocial impairment. This is a striking new finding of clinical importance. The effect on functioning was similar for substance use disorders, other mental disorders, and combined mental and substance use disorders (dual diagnoses), with no gender differences. This finding highlights the need for specialized interventions among general hospital in-patients referred for psychiatric consultation.

Binge drinking and ambulatory blood pressure.

-The effect of alcohol drinking in raising blood pressure (BP) is rapidly reversible. However, there is only limited information on the effect of binge drinking on BP values. In this study, 20 healthy men who were all social drinkers drank alcohol (2.2 g/kg) in controlled circumstances on a Saturday evening. Ambulatory BP measurement (ABPM) values were compared with ABPM values of the same subjects during the previous sober Saturday, separately throughout 6 hours of intoxication, throughout 6 hours when blood alcohol levels decreased, and throughout 6 hangover hours. During the intoxication period, both mean systolic BP and mean diastolic BP were 5 mm Hg higher (P=0.0183 and P=0.0529, respectively) and the pulse was 18 beats per minute faster (P=0.0001) compared with the corresponding sober period during the previous weekend. While blood alcohol levels decreased after drinking, mean systolic BP was 4 mm Hg lower (P=0. 0331), diastolic BP was 5 mm Hg lower (P=0.0058), and pulse was 15 bpm faster (P=0.0001) than during the sober weekend. No statistically significant difference was found between the weekends in BP values during the hangover period. Drinking seems to increase both systolic and diastolic BP during intoxication but not during hangover. During the period when blood alcohol levels are decreasing, usually at night, both pressure levels fall to less than the basic level. These major and rapid changes in BP values might increase the likelihood of strokes, which are seen in increased numbers among young adults, especially during weekends and holidays.
