Influence of stress resilience in adolescence on long-term risk of psoriasis and psoriatic arthritis among men: A prospective register-based cohort study in Sweden.

BACKGROUND: Although stress is considered to be a negative factor for psoriasis, no convincing scientific evidence of this association exists, largely because of difficulties in measuring stress. Stress resilience is the ability to cope with and adapt to stressful events. Stress resilience can be measured in a standardized way and used as a marker for chronic stress. OBJECTIVES: The objective of this study is to investigate whether low stress resilience in adolescence increases the risk for onset of psoriasis and psoriatic arthritis later in life. METHODS: A cohort of Swedish men (mean age 18.3 years), enrolled in compulsory military service between 1968 and 2005, was created using data from the Swedish Military Service Conscription Register (n = 1,669,422). Stress resilience at conscription was estimated using standardized semi-structured interviews, and was divided into three categories: low, medium and high. The men were followed from conscription until new-onset psoriasis or psoriatic arthritis, death or emigration or at the latest until 31 December 2019. Cox regression models adjusted for confounders at conscription were used to obtain hazard ratios (HRs) with 95% confidence intervals (CIs) for incident psoriasis and psoriatic arthritis. RESULTS: Men in the lowest stress resilience category had an increased risk of psoriasis and psoriatic arthritis (HR 1.31 (95% CI 1.26-1.36) and 1.23 (95% CI 1.15-1.32), respectively), compared with those in the highest stress resilience category. When including only hospitalized patients the HRs for psoriasis and psoriatic arthritis in the lowest stress resilience group were 1.79 (1.63-1.98) and 1.53 (1.32-1.77), respectively. CONCLUSIONS: This large, prospective register study suggests that low stress resilience in adolescence is associated with an increased risk of incident psoriasis among men. The results indicate that patients with psoriasis have an inherent psychological vulnerability, and highlight the importance of addressing psychological well-being in the management of psoriasis.

Diverging trends for onset of acute myocardial infarction, heart failure, stroke and mortality in young males: role of changes in obesity and fitness.

BACKGROUND: As opposed to the decreasing overall rates of coronary heart disease (CHD) incidence and overall cardiovascular disease (CVD) mortality, heart failure (HF) and stroke incidence are increasing in young people, potentially due to rising rates of obesity and reduced cardiorespiratory fitness (CRF). OBJECTIVES: We investigated trends in early major CVD outcomes in a large cohort of young men. METHODS: Successive cohorts of Swedish military conscripts from 1971 to 1995 (N = 1,258,432; mean age, 18.3 years) were followed, using data from the National Inpatient and Cause of Death registries. Cox proportional hazard models were used to analyse changes in 21-year CVD event rates. RESULTS: 21-year CVD and all-cause mortality and incidence of acute myocardial infarction (AMI) decreased progressively. Compared with the cohort conscripted in 1971-1975 (reference), the hazard ratios (HRs) for the last 1991-1995 cohort were 0.50 [95% confidence interval (CI) 0.42-0.59] for CVD mortality; 0.57 (95% CI 0.54-0.60) for all-cause mortality; and 0.63 (95% CI 0.53-0.75) for AMI. In contrast, the incidence of ischaemic stroke, intracerebral haemorrhage and HF increased with HRs of 1.43 (95% CI 1.17-1.75), 1.30 (95% CI 1.01-1.68) and 1.84 (95% CI 1.47-2.30), respectively. During the period, rates of obesity increased from 1.04% to 2.61%, whilst CRF scores decreased slightly. Adjustment for these factors influenced these secular trends only moderately. CONCLUSION: Secular trends of young-onset CVD events demonstrated a marked shift from AMI and CVD mortality to HF and stroke incidence. Trends were significantly, though moderately, influenced by changing baseline BMI and CRF.

Urinary cytokines correlate with acute kidney injury in critically ill COVID-19 patients.

BACKGROUND: Acute kidney injury is common in COVID-19 patients admitted to the ICU. Urinary biomarkers are a non-invasive way of assaying renal damage, and so far, urinary cytokines are not fully investigated. The current study aimed to assess urinary cytokine levels in COVID-19 patients. METHODS: Urine was collected from COVID-19 patients (n = 29) in intensive care and compared to a preoperative group of patients (n = 9) with no critical illness. 92 urinary cytokines were analyzed in multiplex using the Olink Target 96 inflammation panel and compared to clinical characteristics, and urinary markers of kidney injury. RESULTS: There were strong correlations between proinflammatory cytokines and between urinary cytokines and urinary kidney injury markers in 29 COVID-19 patients. Several cytokines were correlated to kidney injury, 31 cytokines to AKI stage and 19 cytokines correlated to maximal creatinine. CONCLUSIONS: Urinary inflammatory cytokines from a wide range of immune cell lineages were significantly upregulated during COVID-19 and the upregulation correlated with acute kidney injury as well as urinary markers of kidney tissue damage.

Obesity in adolescent men increases the risk of venous thromboembolism in adult life.

BACKGROUND: As the population of obese and severely obese young adults grows, it is becoming increasingly important to recognize the long-term risks associated with adolescent obesity. OBJECTIVES: This study aimed to determine the association between body mass index (BMI) in young men at enlistment for military service and later risk of venous thromboembolism (VTE). METHODS: Nationwide register-based prospective cohort study of men enlisting 1969 to 2005, followed through the Swedish National Patient and Cause of Death registries. We identified 1 639 838 men (mean age, 18.3 years) free of prior venous thromboembolism, of whom 29 342 were obese (BMI 30 to <35 kg m-2 ) and 7236 severely obese (BMI ≥ 35 kg m-2 ). The participants were followed until a first registered diagnosis of VTE. RESULTS: During a median follow-up of 28 years (interquartile interval, 20 to 36 years), 11 395 cases of deep vein thrombosis and 7270 cases of pulmonary embolism were recorded. Compared with men with a BMI of 18.5 to <20 kg m-2 , men with higher BMI in young adulthood showed an incrementally increasing risk of VTE that was moderately but significantly increased already at normal BMI levels. Adolescent obese men with a BMI of 30 to 35 kg m-2 had an adjusted hazard ratio of 2.93 (95% confidence interval, 2.65 to 3.24) for VTE. Severely obese men with a BMI of ≥35 kg m-2 had a hazard ratio of 4.95 (95% confidence interval, 4.16 to 5.90). CONCLUSIONS: Men who were obese or severely obese in young adulthood had a marked increase in risk of VTE.

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

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

Cardiovascular fitness in early adulthood and future suicidal behaviour in men followed for up to 42 years.

BACKGROUND: Cardiovascular fitness influences many aspects of brain function. However, the relationship between cardiovascular fitness and suicidal behaviour is unknown. Therefore, we aimed to determine whether cardiovascular fitness at age 18 years is associated with future risk of suicide attempt/death. METHOD: We performed a population-based Swedish longitudinal cohort study of male conscripts with no previous or ongoing mental illness (n = 1,136,527). The conscription examination, which took place during 1968-2005, included the cycle ergonometric test and tests of cognitive performance. Future risk of suicide attempt/death over a 5- to 42-year follow-up period was calculated with Cox proportional hazards models controlling for several confounders including familial factors. RESULTS: At least one suicide attempt was recorded for 12,563 men. Death by suicide without a prior attempt was recorded in 4814 additional individuals. In fully adjusted models low cardiovascular fitness was associated with increased risk for future attempt/death by suicide [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.64-1.94]. The HR changed only marginally after exclusion of persons who received in-patient care for depression (HR 1.76, 95% CI 1.61-1.94). Poor performance on both the cardiovascular fitness and cognitive tests was associated with a fivefold increased risk of suicide attempt or suicide death (HR 5.46, 95% CI 4.78-6.24). CONCLUSIONS: Lower cardiovascular fitness at age 18 years was, after adjustment for a number of potential confounders, associated with an increased risk of attempt/death by suicide in adulthood. It remains to be clarified whether interventions designed to improve fitness in teens can influence the risk of suicidal behaviour later in life.

Neuropeptide levels in Dercum's disease (adiposis dolorosa).

Dercum's disease (adiposis dolorosa) is characterised by adiposity and chronic pain in the adipose tissue. It has been proposed that conditions encompassing chronic pain have altered concentrations of neuropeptides involved in pain transmission. The aim of this investigation was to examine whether patients with Dercum's disease have abnormal concentrations of different neuropeptides. In cerebrospinal fluid (CSF) and in plasma (P) from 53 patients with Dercum's disease substance P-like immunoreactivity (SP-LI), neuropeptide Y-like immunoreactivity (NPY-LI), ß-endorphin-like immunoreactivity (ß-END-LI), calcitonin gene-related peptidelike immunoreactivity (CGRP-LI), met-enkephalin-like immunoreactivity (m-ENK-LI), vasoactive intestinal polypeptide-like immunoreactivity (VIP-LI), somatostatin (SOM-LI), γ2-melanocyte-stimulating hormone-like immunoreactivity (γ2-MSH-LI), and dynorphin-like immunoreactivity (DYN-LI) were measured. Three of the substances were also measured in a control group. The CSF concentration of SP was statistically significantly lower in the Dercum group than in the control group, whereas NPY-LI and b-END-LI were borderline statistically significantly lower and higher, respectively, in Dercum patients compared to controls. Compared with reference values, CSF-MSH-LI levels were slightly elevated and CSF-NPY-LI levels were slightly lowered in the Dercum group. The other substances in both CSF and plasma were within the reference values with a high degree of statistical significance. In conclusion, altered levels of neuropeptides that have previously been seen in different pain conditions cannot clearly be demonstrated in Dercum's disease.

Transfusion of intra-operative autologous whole blood: influence on complement activation and interleukin formation.

BACKGROUND AND OBJECTIVES: Transfusion of autologous whole blood is one available method to reduce the need for allogenic blood transfusion. The objective of this study was to investigate the safety of transfusion of intra-operative autologous whole blood by monitoring plasma concentration of laboratory variables and adverse events after transfusion with the Sangvia(®) system. MATERIALS AND METHODS: The clinical trial was designed as an open, prospective, multi-centre study, and a total of 20 patients undergoing primary hip arthroplasty were included. Systemic blood samples were taken and analysed preoperatively, at transfusion start and end and at 3, 6, 24 and 48 h after the transfusion. RESULTS: Elevated values of complement activation and pro-inflammatory cytokines were seen in the intra-operatively collected blood but the impact on systemic levels were limited with low peak levels, systemic elevations before transfusion and normalization during the study period. Elevated levels of free haemoglobin and potassium were also detected in the intra-operatively collected blood, but systemic values were within reference values after the transfusion. No clinically relevant adverse event occurred during the study. CONCLUSION: Inflammatory mediators and plasma haemoglobin were increased in intra-operatively salvaged and filtered blood compared to circulatory levels. Intra-operative retransfusion of autologous whole blood caused a transient systemic increase that normalized in the early postoperative period. There were no significant adverse events reported in the study. These data suggest that the Sangvia(®) system can be used for intra-operative collection and retransfusion of salvaged blood.

Fish consumption and school grades in Swedish adolescents: a study of the large general population.

AIM: To study the associations between fish intake and academic achievement as cognitive parameter among Swedish adolescents. METHODS: In 2000, a questionnaire including respiratory items, socioeconomic conditions and dietary information was mailed to all schoolchildren (n = 18 158), aged 15 and living in Västra Götaland region of Sweden. The questionnaire was returned by 10 837 subjects. One year later, the total school grades for each subject who had completed the questionnaire and who included their full personal identification number were obtained from the national registers. Multiple linear regression models were applied to evaluate the association between fish intake and academic grades among 9448 schoolchildren, while adjusting for potential confounders, e.g. parents' education. RESULTS: Grades were higher in subjects with fish consumption once a week compared with subjects with fish consumption of less than once a week (reference group) [increment in estimate 14.5, 95% confidence interval (CI) 11.8-17.1]. Grades were even higher in subjects with fish consumption of more than once a week compared with the reference group (increment in estimate 19.9, 95% CI 16.5-23.3). In the model stratified for parents' education, there were still higher grades among subjects with frequent fish intake in all educational strata (p < 0.01). CONCLUSION: Frequent fish intake among schoolchildren may provide benefits in terms of academic achievement.

Future marginalisation and mortality in young Swedish men with non-psychotic psychiatric disorders and the resilience effect of cognitive ability: a prospective, population-based study.

OBJECTIVE: Large-scale studies examining future trajectories of marginalisation and health in adolescents with mental illness are scarce. The aim of this study was to examine if non-psychotic psychiatric disorders (NPDs) were associated with future indicators of marginalisation and mortality. We also aimed to determine whether these associations might be mediated by education level and attenuated by high cognitive ability. DESIGN: This is a prospective cohort study with baseline data from the Swedish Conscription register. SETTING: The study was carried out in Sweden from 1969 to 2005. PARTICIPANTS: All of the participants were 18-year-old men at mandatory conscription in Sweden between 1969 and 2005 (n=1 609 690). MEASURES: NPDs were clinically diagnosed at conscription. Cognitive ability was measured by a standardised IQ test at conscription. National register data covered information on welfare support, long-term unemployment, disability pension (DP) and mortality over a period of 1-36 years. RESULTS: NPD at the age of 18 years was a predictor of future welfare support, OR 3.73 (95% CI 3.65 to 3.80); long-term unemployment, OR 1.97 (95% CI 1.94 to 2.01); DP, HR 2.95 (95% CI 2.89 to 3.02); and mortality, HR 2.45 (2.33-2.52). The adjusted models suggested that these associations were not confounded by fathers' educational level, cognitive ability had only a minor attenuating effect on most associations and the mediating effect of own educational level was small. CONCLUSIONS: The present study underlines a higher prevalence of future adversities in young men experiencing NPDs at the age of 18 years. It also indicates that higher cognitive ability may work as a potential resilience factor against future marginalisation and mortality.

Peripheral infusion of IGF-I selectively induces neurogenesis in the adult rat hippocampus.

In several species, including humans, the dentate granule cell layer (GCL) of the hippocampus exhibits neurogenesis throughout adult life. The ability to regulate adult neurogenesis pharmacologically may be of therapeutic value as a mechanism for replacing lost neurons. Insulin-like growth factor-I (IGF-I) is a growth-promoting peptide hormone that has been shown to have neurotrophic properties. The relationship between IGF-I and adult hippocampal neurogenesis is to date unknown. The aim of this study was to investigate the effect of the peripheral administration of IGF-I on cellular proliferation in the dentate subgranular proliferative zone, which contains neuronal progenitor cells, and on the subsequent migration and differentiation of progenitor cells within the GCL. Using bromodeoxyuridine (BrdU) labeling, we found a significant increase of BrdU-immunoreactive progenitors in the GCL after 6 d of peripheral IGF-I administration. To determine the cell fate in progenitor progeny, we characterized the colocalization of BrdU-immunolabeled cells with cell-specific markers. In animals treated with IGF-I for 20 d, BrdU-positive cells increased significantly. Furthermore, the fraction of newly generated neurons in the GCL increased, as evaluated by the neuronal markers Calbindin D(28K), microtubule-associated protein-2, and NeuN. There was no difference in the fraction of newly generated astrocytes. Thus, our results show that peripheral infusion of IGF-I increases progenitor cell proliferation and selectively induces neurogenesis in the progeny of adult neural progenitor cells. This corresponds to a 78 +/- 17% (p < 0.001) increase in the number of new neurons in IGF-I-treated animals compared with controls.

A prospective study of suicidal burns admitted to the Harare burns unit.

The aim of this study was to obtain prospective information on suicidal (attempted suicide) burns patients admitted to the Harare burns unit during 1995-1998. Forty-seven patients, 42 females (89%) and five males (11%), evenly distributed throughout the period of study, were included. The median age was 25 years, range 13 to 50 years. Thirty were housewives (64%). Women married according to customary law were the group most at risk. All patients were burnt by flame after dousing themselves with paraffin or petrol. Conflict in love relationships was the most common circumstance leading to attempted suicide. The median Total Body Surface Area (TBSA) burnt was 60%, range 10-90%, for all patients, 25%, range 10-40%, for those who survived and 65%, range 20-95%, for those who died. Surgery was performed on 16 patients (34%). Mortality was 68%. The overall median hospital stay for all patients was 10 days, range 0-322 days, and 5 days, range 0-322 days, for those who died.

A Prospective study on the epidemiology of burns in patients admitted to the Harare burn units.

The purpose of this study was to record the causes and the magnitudes of burn injuries prospectively and to evaluate the outcome of treatment of patients admitted to the burn units in Harare. The median age of the 451 patients included was 6 years (range: 1 month to 71 years), 54% were female and 46% male. The burn injuries were caused by flame in 51% of the cases and hot liquids in 47%. The overall median total body surface area burnt was 13% (range: 0.5 to 99%). Parasuicidal burns (attempted suicides) were noted in 11% of the patients with a median total body surface area burnt of 30% and mortality of 73%. Lodgers were overrepresented in the material. Delayed split skin grafting was done on 26% of the patients and early primary excision and skin grafting on 3%. The overall median hospital stay was 15 days (range: 0 to 229 days). The median hospital stay for patients with delayed split skin grafting was 42 days and that for those with primary excision and split skin grafting was 17 days. The overall mortality was 22%. All patients with burns larger than 65% of the total body surface area died. Burn injuries were more frequent and larger with higher mortality in females than in males. Flame was the major cause of the burns. Self-inflicted burns, noted mainly in young women, resulted in 73% mortality. Primary excision and grafting reduced hospital stay by 60% compared to delayed skin grafting.

A prospective double blind randomized study comparing the need for blood transfusion with terlipressin or a placebo during early excision and grafting of burns.

INTRODUCTION: Early excision and skin grafting has become the standard of good burn management, but it is associated with major blood loss. AIM: To determine the haemostatic effect of terlipressin compared with placebo. MATERIAL AND METHODS: Fifty-one patients with burns of 10-20% total body surface area had early excision and split skin grafting of deep burns. The surface area of the burn wound and of the healed graft were measured by planimetry. The patients were randomly allocated to medication, either terlipressin or placebo. Blood loss and number of transfused units of blood were recorded. RESULTS: Twenty-one patients received terlipressin, 13 received terlipressin late (cross-over) and 17 received placebo. Six out of 21 patients exposed to terlipressin were transfused with eleven units of packed red blood cells. Seven out of 13 patients crossed over from placebo to terlipressin (late terlipressin) were transfused with 17 units of blood. Eight out of 17 patients exposed to the placebo were transfused with 22 units of blood (P < 0.05). Graft healing was 1055 +/- 609 cm2 out of 1452 +/- 11 cm2 in terlipressin and 914 +/- 633 cm2 out of 1288 +/- 720 cm2 in the placebo group (n.s.). CONCLUSION: Terlipressin reduced the need for blood transfusion by a factor of 2.5 compared to a placebo without impairment of graft healing.

Bone grafts to the nose in Binder's syndrome (maxillonasal dysplasia): a follow-up of eleven patients with the use of profile roentgenograms.

Bone grafts are used to lengthen the dorsum and elevate the tip of the nose in patients with Binder's syndrome. Disappointing long-term results in some patients generally have been assumed to be a result of resorption and/or displacement of the grafts. Treatment outcome was studied in 11 patients with the use of serial profile roentgenograms. At 40 months, the mean values after surgery were reduction of the initial transplant length by 28 percent and reduction of the transplant angle by 4 degrees. The initial nose length was increased by 1 mm, and nose tip projection was increased by 2 mm. Although the mean changes of nose length and nose tip projection seemed small, treatment outcome varied considerably between patients. In contrast with earlier assumptions, no correlation could be found between the degree of transplant resorption and/or displacement and the effect of surgery on nose length and nose tip projection.

Dermabrasion of large congenital melanocytic naevi in neonates.

We describe our findings in a series of 12 patients with large congenital melanocytic naevi treated with dermabrasion between the first and fourteenth week of life. Postoperative follow-up ranged from 1-16 years. In all but two cases dermabrasion resulted in an appreciable and stable reduction of the hyperpigmentation, possibly by reducing the number of pigmented cells in the epidermis. In six of our 12 patients, reconstruction using grafts and flaps was done to improve the aesthetic result. Seven years after dermabrasion, one patient developed a minimal deviation melanoma in the treated area, but his subsequent clinical course has been uneventful.

Staged reconstruction of hypospadias with chordee: outcome and costs.

One-hundred-and-forty patients with hypospadias and chordee were reviewed from the points of view of surgical results and hospital costs. Ninety cases constituted a historical series, and 50 patients a current personal series. All were operated on by Byars' two-staged protocol with release of the chordee followed by urethral reconstruction. Complementary surgery was necessary in a total of 37 instances, particularly in cryptohypospadias with tight chordee and in penoscrotal hypospadias. Increasing personal experience with the operative technique has gradually reduced the need for such procedures. The final results were satisfactory in all but one patient, who has had recurring strictures. The hospital cost for a patient according to basic assumptions was 100,280 SEK (about US$ 14,000). If the time in operating theatre could be shortened by 10 minutes, the stay in hospital reduced by one day, and the complication rate halved, the overall cost would be reduced by 14.3%. Consequently we believe that staged reconstruction remains an attractive alternative in cases of hypospadias with marked curvation of the penis.

The effect of triglycyl-lysine-vasopressin (terlipressin INN, Glypressin) on skin blood flow, measured with laser Doppler flowmetry, thermography and plethysmography. A dose-response study.

Triglycyl-lysine-vasopressin (TGLVP) has been shown to reduce blood loss in connection with early excision of experimentally induced burns in pigs. In order to determine an appropriate dosage of TGLVP in patients with burns, a dose-response study was undertaken. TGLVP was administered intravenously in various doses to healthy volunteers, and skin blood flow was measured with laser Doppler flowmetry, thermography and plethysmography. Blood pressure, heart rate and electrocardiac activity were monitored as well as serum and urine changes. The doses of 5, 10 and 20 micrograms TGLVP/kg b.wt. caused statistically significant reduction of skin blood flow; minimal values were 35, 26 and 25% of predrug values for the three doses, respectively. Thermography and plethysmography were less sensitive for detecting effects of TGLVP than laser Doppler flowmetry. Minor effects on blood pressure and heart rate were recorded after TGLVP, but no disturbances in electrocardiac activity. Urinalyses revealed an antidiuretic action of TGLVP. The study supports earlier findings and suggests a dose level of TGLVP for the use in excision of burns.

[Female sterilization--safe and irreversible?]. / Kvinnlig sterilisering--säker och irreversibel?

PIP: With 6 case studies as illustrations, sterilization methods for women, their safety and reliability, reversibility and irreversibility are discussed. In Sweden the average pregnancy rate following sterilization is .3-.7%, in other countries 1-2%; about 3% of Swedish women subsequently regret the operation. The most frequently used methods are electrocoagulation and application of the Yoon band for tubal ligation. The use of electrocoagulation alone is not sufficient. Some of the complications after these methods include bleeding, singeing of intestines, lower abdominal pain due to torsion of distal tubal ends, and faulty placement of tubal rings. The reliability of sterilization in never 100%, as illustrated by 3 cases: a 41-year-old woman was sterilized by laparoscopy and became pregnant 7 years later, abortion and bilateral tubal resection was performed; another woman became pregnant 1.5 years after Yoon band sterilization and carried the pregnancy to term; the 3rd woman became pregnant 4 weeks after minilaparotomy (Pomeroy method) and delivered the child. Refertilization was studied in a survey of 100 Canadian women who sought reversal of sterility. They were aged 22-43, with an average of 2 children; most claimed that inadequate information had been provided about the procedure; and most desired reversal because of a new relationship. Although sterilization is regarded as a definitive method of preventing pregnancy, modern microsurgery can restore fertility up to 80% (vs. 50% by conventional tubal surgery). Often sterilization is performed after abortion in young women (368 cases out of 6415 sterilizations in Sweden in 1983) who later regret their decision. It is recommended thet the legal implications of restricting sterilization for women under 30 be explored because of the high medical and emotional risks involved.^ieng

Tissue factor non-coagulant signaling - molecular mechanisms and biological consequences with a focus on cell migration and apoptosis.

Tissue factor (TF), a transmembrane glycoprotein, is the main initiator of the blood coagulation cascade. TF is also recognized as a true signaling receptor. There is accumulating evidence that the downstream signaling effects of the TF complexes are transduced by several mechanisms, including: activation of protease-activated receptor (PAR)-1 and PAR-2, and the PAR-dependent pathways, via the TF cytoplasmic domain and by transactivation of receptor tyrosine kinases. Triggering of signaling cascades such as the mitogen-activated protein kinase and phosphoinositide 3-kinase/AKT pathways couples TF to a multitude of functions within the cell, such as proliferation, cell migration, and survival. Thus, TF has a Janus face; on the one hand, it has vital life-maintaining functions, and on the other it has harmful effects, exemplified by inflammation, the acute coronary syndromes, and cancer. TF mediates a broad spectrum of signaling mechanisms. Learning more about these different mechanisms/pathways will lead to new treatment strategies, which can ultimately be personalized.
