Mental health and growing up factsheet. Drugs and alcohol - what parents need to know.

Information about drugs and alcohol - what parents need to know: information for parents, carers and anyone who works with young people. About this leaflet This is one in a series of leaflets for parents, teachers and young people entitled Mental Health and Growing Up. These leaflets aim to provide practical, up-to-date information about mental health problems (emotional, behavioural and psychiatric disorders) that can affect children and young people. This leaflet offers practical advice for parents, teachers and carers who are worried that a young person is misusing drugs or alcohol. Why do I need to know about a young person using drugs or alcohol? Many young people smoke, drink alcohol and may try drugs. It is important you are aware of this and do not ignore it as a time when they are just having fun or experimenting. It doesnââ,‰"¢t take much for the young people to soon lose control and to need help to recover from this problem. How common is it? By the age of 16, up to half of young people have tried an illegal drug. Young people are trying drugs earlier and more are drinking alcohol. What are the different types of drugs which cause problems? The most commonly used, readily available and strongly addictive drugs are tobacco and alcohol. There are numerous others that can be addictive. Alcohol and cannabis are sometimes seen as ââ,¬Ëogatewayââ,‰"¢ drugs that lead to the world of other drugs like cocaine and heroin. Drugs are also classed as ââ,¬Ëolegalââ,‰"¢ andââ,¬Ëoillegalââ,‰"¢. The obviously illegal drugs include cannabis (hash), speed (amphetamines), ecstasy (E), cocaine and heroin. Using ââ,¬Ëolegalââ,‰"¢ drugs (like cigarettes, alcohol, petrol, glue) does not mean they are safe or allowed to be misused. It just means they may be bought or sold for specific purposes and are limited to use by specific age groups. There are clear laws regarding alcohol and young people. For more detailed information on various drugs, their side-effects and the law, see ââ,¬ËoFurther Informationââ,‰"¢ at the end of the factsheet. Why do young people use drugs or alcohol? Young people may try or use drugs or alcohol for various reasons. They may do it for fun, because they are curious, or to be like their friends. Some are experimenting with the feeling of intoxication. Sometimes they use it to cope with difficult situations or feelings of worry and low mood. A young person is more likely to try or use drugs or alcohol if they hang out or stay with friends or family who use them. What can be the problems related to using drugs or alcohol? Drugs and alcohol can have different effects on different people. In young people especially the effects can be unpredictable and potentially dangerous. Even medications for sleep or painkillers can be addictive and harmful if not used the way they are prescribed by a doctor. Drugs and alcohol can damage health. Sharing needles or equipment can cause serious infections, such as HIV and hepatitis. Accidents, arguments and fights are more likely after drinking and drug use. Young people are more likely to engage in unprotected sex when using drugs. Using drugs can lead to serious mental illnesses, such as psychosis and depression. When does it become addiction or problem? It is very difficult to know when exactly using drugs or alcohol is more than just ââ,¬Ëocasualââ,‰"¢. Addiction becomes more obvious when the young person spends most of their time thinking about, looking for or using drugs. Drugs or alcohol then become the focus of the young personââ,‰"¢s life. They ignore their usual work, such as not doing their schoolwork, or stop doing their usual hobbies/sports such as dancing or football. How do I know if there is a problem or addiction? Occasional use can be very difficult to detect. If the young person is using on a regular basis, their behaviour often changes. Look for signs such as: ïâ?s§ unexplained moodiness ïâ?s§ behaviour that is ââ,¬Ëoout of character' ïâ?s§ loss of interest in school or friends ïâ?s§ unexplained loss of clothes or money ïâ?s§ unusual smells and items like silver foil, needle covers. Remember, the above changes can also mean other problems, such as depression, rather than using drugs. What do I do if I am worried? If you suspect young person is using drugs, remember some general rules. ïâ?s§ Pay attention to what the child is doing, including schoolwork, friends and leisure time. ïâ?s§ Learn about the effects of alcohol and drugs (see websites listed below). ïâ?s§ Listen to what the child says about alcohol and drugs, and talk about it with them. ïâ?s§ Encourage the young person to be informed and responsible about drugs and alcohol. ïâ?s§ Talk to other parents, friends or teachers about drugs - the facts and your fears and seek help. If someone in the family or close friend is using drugs or alcohol, it is important that they seek help too. It may be hard to expect the young person to give up, especially if a parent or carer is using it too. My child is abusing drugs. What do I do? ïâ?s§ If your child is using drugs or alcohol, seek help. ïâ?s§ Do stay calm and make sure of facts. ïâ?s§ Don't give up on them, get into long debates or arguments when they are drunk, stoned or high. ïâ?s§ Donââ,‰"¢t be angry or blame themââ,‰?othey need your help and trust to make journey of recovery. Where can I get help? You can talk in confidence to a professional like your GP or practice nurse, a local drug project or your local child and adolescent mental health. They can refer your child to relevant services and they will be able to offer you advice and support. You may also be able to seek help through a school nurse, teacher or social worker. You can find this information from your local area telephone book or council website, or ask for the address from your health centre.

Prefrailty and chronic morbidity in the youngest old: an insight from the Lausanne Cohort Lc65+.

OBJECTIVES: To estimate the prevalence of prefrailty, frailty, comorbidity, and disability in the youngest old and to identify chronic diseases associated with individual frailty criteria. DESIGN: Population-based cohort study of noninstitutionalized elderly adults at baseline; cross-sectional analysis. SETTING: Lausanne, Switzerland. PARTICIPANTS: One thousand two hundred eighty-three individuals with complete data on frailty, aged 65 to 70 (58.5% women). MEASUREMENTS: Frailty was assessed according to an adaptation of Fried's criteria (shrinking, weakness, exhaustion, slowness, and low activity, three criteria needed for the diagnosis of frailty, 1 to 2 for prefrailty). Other outcomes were diseases diagnosed by a doctor (≥ 2 chronic diseases: comorbidity) and limitations in activities of daily living (ADLs, basic and instrumental). RESULTS: At baseline, of 1,283 participants 71.1% were classified as nonfrail, 26.4% as prefrail, and 2.5% as frail. The proportion of women increased across these three groups (56.5%, 62.8%, and 71.9%, respectively; P = .01), as did the proportion of individuals with one or more chronic diseases (68.0%, 82.8%, and 90.6%, respectively; P < .001) and the proportion with basic or instrumental ADL disability (1.6%, 10.3%, and 59.4%, respectively; P < .001). Weakness (low grip strength) was the most frequent criterion (14.3%). Prefrail participants had significantly more comorbidity and ADL disability than nonfrail participants (P < .001). When present in isolation, weakness was associated with two to three times greater prevalence of coronary heart disease, other heart diseases, diabetes mellitus, and arthritis. Similarly, a significant association was identified between exhaustion and depression. CONCLUSION: Prefrailty is common in the youngest old. The most prevalent frailty criterion is weakness, which is associated with cardiovascular diseases. Longitudinal studies of the evolution of prefrailty should explore the role of potential interactions between individual frailty criteria and specific chronic diseases.

Nutrición enteral en el paciente neurológico: ¿es suficiente el contenido en vitamina D en las fórmulas de uso habitual?

INTRODUCTION Vitamin D deficiency produces inadequate bone mineralization, proximal muscle weakness, abnormal gait and increased risk of falls and fractures. Moreover, in epidemiological studies, has been associated with increased risk of cancer, autoimmune diseases, type 1 and 2 diabetes, rheumatoid arthritis, multiple sclerosis, infectious diseases, cardiovascular diseases and depression. When synthesis through the skin by sun exposure is not possible and the patient can not eat by mouth, as in the advanced stages of various neurological diseases, the supply of vitamin D has to be done by enteral nutrition. OBJECTIVES The aim of this study is to review the role of vitamin D in a common group of neurological conditions that often require artificial nutrition and analyze whether the vitamin D of different enteral nutrition formulas is adequate to meet the needs of this group of patients. RESULTS Numerous studies have shown the association between vitamin D deficiency and increased incidence of dementia, stroke and other neurodegenerative diseases. Interventions aimed to increase levels of vit. D and its effects on functional (falls, pain, quality of life) and cardiovascular goals (cardiovascular death, stroke, myocardial infarction, cardiovascular risk factors) have obtained as highlight data a clear reduction of falls and fractures, while the evidence for the other parameters studied is still limited and inconsistent. The content of calcium and vitamin D of enteral formulas is legislated in our country. The total amount of vitamin D for a daily intake of 1,500-2,000 kcal ranges between 300 and 1,600 IU/d (mean ± SD: 32.9 ± 8.5 mg/100 kcal) in the complete formulas for enteral nutrition most commonly used. 50% of the diets studied, for an intake of 2,000 kcal/d, and 90% for an intake of 1,500 kcal/d, provide less than 600 IU/d of vitamin D. DISCUSSION Some revised recently guidelines published recommendations of daily intake of vitamin D. The document published by the U.S. Institute of Medicine recommended for adults between 19 and 70 years, 600 IU/d and up from 70, proposes 800 IU/d of vitamin D. These amounts are deemed insufficient by other scientific societies to state that to achieve blood levels of 25 (OH) D equal or greater than 30 ng/ml may be required a daily intake of 1,500-2,000 IU and a number two or three times higher if previous deficiency exists. CONCLUSIONS Further controlled studies are needed to ascertain which is the appropriate dose of vitamin D in advanced stages of neurological disease, where sun exposure is difficult and unlikely. We suggest that the vitamin D content should probably be reconsidered in enteral nutrition formulas, which, in light of recent publications appear as clearly insufficient for standard energy intakes (1,500-2,000 kcal).

Telehealth system (e-CUIDATE) to improve quality of life in breast cancer survivors: rationale and study protocol for a randomized clinical trial.

BACKGROUND Breast cancer survivors suffer physical impairment after oncology treatment. This impairment reduces quality of life (QoL) and increase the prevalence of handicaps associated to unhealthy lifestyle (for example, decreased aerobic capacity and strength, weight gain, and fatigue). Recent work has shown that exercise adapted to individual characteristics of patients is related to improved overall and disease-free survival. Nowadays, technological support using telerehabilitation systems is a promising strategy with great advantage of a quick and efficient contact with the health professional. It is not known the role of telerehabilitation through therapeutic exercise as a support tool to implement an active lifestyle which has been shown as an effective resource to improve fitness and reduce musculoskeletal disorders of these women. METHODS / DESIGN This study will use a two-arm, assessor blinded, parallel randomized controlled trial design. People will be eligible if: their diagnosis is of stages I, II, or IIIA breast cancer; they are without chronic disease or orthopedic issues that would interfere with ability to participate in a physical activity program; they had access to the Internet and basic knowledge of computer use or living with a relative who has this knowledge; they had completed adjuvant therapy except for hormone therapy and not have a history of cancer recurrence; and they have an interest in improving lifestyle. Participants will be randomized into e-CUIDATE or usual care groups. E-CUIDATE give participants access to a range of contents: planning exercise arranged in series with breathing exercises, mobility, strength, and stretching. All of these exercises will be assigned to women in the telerehabilitation group according to perceived needs. The control group will be asked to maintain their usual routine. Study endpoints will be assessed after 8 weeks (immediate effects) and after 6 months. The primary outcome will be QoL measured by The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 version 3.0 and breast module called The European Organization for Research and Treatment of Cancer Breast Cancer-Specific Quality of Life questionnaire. The secondary outcomes: pain (algometry, Visual Analogue Scale, Brief Pain Inventory short form); body composition; physical measurement (abdominal test, handgrip strength, back muscle strength, and multiple sit-to-stand test); cardiorespiratory fitness (International Fitness Scale, 6-minute walk test, International Physical Activity Questionnaire-Short Form); fatigue (Piper Fatigue Scale and Borg Fatigue Scale); anxiety and depression (Hospital Anxiety and Depression Scale); cognitive function (Trail Making Test and Auditory Consonant Trigram); accelerometry; lymphedema; and anthropometric perimeters. DISCUSSION This study investigates the feasibility and effectiveness of a telerehabilitation system during adjuvant treatment of patients with breast cancer. If this treatment option is effective, telehealth systems could offer a choice of supportive care to cancer patients during the survivorship phase. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01801527.

Gender differences in premorbid, entry, treatment, and outcome characteristics in a treated epidemiological sample of 661 patients with first episode psychosis.

OBJECTIVES: Gender differences in psychotic disorder have been observed in terms of illness onset and course; however, past research has been limited by inconsistencies between studies and the lack of epidemiological representative of samples assessed. Thus, the aim of this study was to elucidate gender differences in a treated epidemiological sample of patients with first episode psychosis (FEP). METHODS: A medical file audit was used to collect data on premorbid, entry, treatment and 18-month outcome characteristics of 661 FEP consecutive patients treated at the Early Psychosis Prevention and Intervention Centre (EPPIC), Melbourne, Australia. RESULTS: Prior to onset of psychosis, females were more likely to have a history of suicide attempts (p=.011) and depression (p=.001). At service entry, females were more likely to have depressive symptoms (p=.007). Conversely, males had marked substance use problems that were evident prior to admission (p<.001) and persisted through treatment (p<.001). At service entry, males also experienced more severe psychopathology (p<.001) and lower levels of functioning (GAF, p=.008; unemployment/not studying p=.004; living with family, p=.003). Treatment non-compliance (p<.001) and frequent hospitalisations (p=.047) were also common for males with FEP. At service discharge males had significantly lower levels of functioning (GAF, p=.008; unemployment/not studying p=.040; living with family, p=.001) compared to females with FEP. CONCLUSIONS: Gender differences are evident in illness course of patients with FEP, particularly with respect to past history of psychopathology and functioning at presentation and at service discharge. Strategies to deal with these gender differences need to be considered in early intervention programs.

BrainCheck - a very brief tool to detect incipient cognitive decline: optimized case-finding combining patient- and informant-based data.

INTRODUCTION: Optimal identification of subtle cognitive impairment in the primary care setting requires a very brief tool combining (a) patients' subjective impairments, (b) cognitive testing, and (c) information from informants. The present study developed a new, very quick and easily administered case-finding tool combining these assessments ('BrainCheck') and tested the feasibility and validity of this instrument in two independent studies. METHODS: We developed a case-finding tool comprised of patient-directed (a) questions about memory and depression and (b) clock drawing, and (c) the informant-directed 7-item version of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). Feasibility study: 52 general practitioners rated the feasibility and acceptance of the patient-directed tool. Validation study: An independent group of 288 Memory Clinic patients (mean ± SD age = 76.6 ± 7.9, education = 12.0 ± 2.6; 53.8% female) with diagnoses of mild cognitive impairment (n = 80), probable Alzheimer's disease (n = 185), or major depression (n = 23) and 126 demographically matched, cognitively healthy volunteer participants (age = 75.2 ± 8.8, education = 12.5 ± 2.7; 40% female) partook. All patient and healthy control participants were administered the patient-directed tool, and informants of 113 patient and 70 healthy control participants completed the very short IQCODE. RESULTS: Feasibility study: General practitioners rated the patient-directed tool as highly feasible and acceptable. Validation study: A Classification and Regression Tree analysis generated an algorithm to categorize patient-directed data which resulted in a correct classification rate (CCR) of 81.2% (sensitivity = 83.0%, specificity = 79.4%). Critically, the CCR of the combined patient- and informant-directed instruments (BrainCheck) reached nearly 90% (that is 89.4%; sensitivity = 97.4%, specificity = 81.6%). CONCLUSION: A new and very brief instrument for general practitioners, 'BrainCheck', combined three sources of information deemed critical for effective case-finding (that is, patients' subject impairments, cognitive testing, informant information) and resulted in a nearly 90% CCR. Thus, it provides a very efficient and valid tool to aid general practitioners in deciding whether patients with suspected cognitive impairments should be further evaluated or not ('watchful waiting').

Factors influencing maternal mental health after the birth of a child with a cleft in benin and in Switzerland.

Objective: The main objective of the study is to identify practical and cultural factors influencing the mental health of mothers of children with an orofacial cleft in Benin and to compare it with a sample of Swiss mothers in the same conditions. Method: Thirty-six mothers of children with an orofacial cleft in Benin and 40 mothers of children with an orofacial cleft in Switzerland were interviewed about practical and emotional aspects concerning their child and their own lives. Then, they completed the Perinatal Postraumatic Stress Questionnaire and the Beck Depression Inventory. Results: Mothers in Benin had significantly higher posttraumatic stress and depression symptoms compared with mothers in Switzerland. Depression symptoms were higher in Beninese mothers coming from urban areas, in Beninese mothers with few or no other children, and in Beninese mothers whose child was operated on at a more advanced age. Discussion: This study stressed the importance of cultural differences in perceptions of orofacial clefts in order to provide appropriate care to patients and their families. In particular, wide campaigns of information should help parents to understand the cleft origin and the medical staff in small dispensaries to provide adequate support and care. This may diminish anxiety concerning the child's short- and long-term prognosis. Creation of a Beninese parental support group for children with clefts and their families could be another way to provide information and support where multidisciplinary care is not available.

Cancer risk in the Swiss HIV Cohort Study: associations with immunodeficiency, smoking, and highly active antiretroviral therapy.

BACKGROUND: Persons infected with human immunodeficiency virus (HIV) have an increased risk for several cancers, but the influences of behavioral risk factors, such as smoking and intravenous drug use, and highly active antiretroviral therapy (HAART) on cancer risk are not clear. METHODS: Patient records were linked between the Swiss HIV Cohort Study and Swiss cantonal cancer registries. Observed and expected numbers of incident cancers were assessed in 7304 persons infected with HIV followed for 28,836 person-years. Relative risks for cancer compared with those for the general population were determined by estimating cancer registry-, sex-, age-, and period-standardized incidence ratios (SIRs). RESULTS: Highly elevated SIRs were confirmed in persons infected with HIV for Kaposi sarcoma (KS) (SIR = 192, 95% confidence interval [CI] = 170 to 217) and non-Hodgkin lymphoma (SIR = 76.4, 95% CI = 66.5 to 87.4). Statistically significantly elevated SIRs were also observed for anal cancer (SIR = 33.4, 95% CI = 10.5 to 78.6); Hodgkin lymphoma (SIR = 17.3, 95% CI = 10.2 to 27.4); cancers of the cervix (SIR = 8.0, 95% CI = 2.9 to 17.4); liver (SIR = 7.0, 95% CI = 2.2 to 16.5); lip, mouth, and pharynx (SIR = 4.1, 95% CI = 2.1 to 7.4); trachea, lung, and bronchus (SIR = 3.2, 95% CI = 1.7 to 5.4); and skin, nonmelanomatous (SIR = 3.2, 95% CI = 2.2 to 4.5). In HAART users, SIRs for KS (SIR = 25.3, 95% CI = 10.8 to 50.1) and non-Hodgkin lymphoma (SIR = 24.2, 95% CI = 15.0 to 37.1) were lower than those for nonusers (KS SIR = 239, 95% CI = 211 to 270; non-Hodgkin lymphoma SIR = 99.3, 95% CI = 85.8 to 114). Among HAART users, however, the SIR (although not absolute numbers) for Hodgkin lymphoma (SIR = 36.2, 95% CI = 16.4 to 68.9) was comparable to that for KS and non-Hodgkin lymphoma. No clear impact of HAART on SIRs emerged for cervical cancer or non-acquired immunodeficiency syndrome-defining cancers. Cancers of the lung, lip, mouth, or pharynx were not observed among nonsmokers. CONCLUSION: In persons infected with HIV, HAART use may prevent most excess risk of KS and non-Hodgkin lymphoma, but not that of Hodgkin lymphoma and other non-acquired immunodeficiency syndrome-defining cancers. No cancers of the lip, mouth, pharynx, or lung were observed in nonsmokers.

Health-Related Quality of Life in patients with hepatitis C in double and triple therapy

Abstract OBJECTIVE Comparing Health-Related Quality of Life (HRQoL) scores in patients with chronic hepatitis C undergoing double and triple antiviral therapy and analyzing possible factors related to HRQoL. METHOD HRQoL was assessed using the Short Form 36 and Chronic Liver Disease Questionnaire, which were applied at baseline and at weeks 4, 12 and 16 of treatment to 32 patients divided into two groups: double therapy with pegylated interferon (IFN-PEG) and ribavirin, and triple therapy with PEG-IFN, ribavirin and telaprevir. RESULTS The reduction of HRQoL was greater in patients receiving triple therapy compared to those treated with two drugs, the most critical time is at 12 weeks in both groups. After removal of telaprevir, the triple therapy group significantly improved their HRQoL scores. Anxiety and depression before treatment, employment status and race are significantly related to diminished HRQoL. CONCLUSION Patients undergoing double and triple therapy have diminished HRQoL indexes, but the addition of telaprevir chooses a more significant decrease.

Iodine-131-labeled MAb F(ab')2 fragments are more efficient and less toxic than intact anti-CEA antibodies in radioimmunotherapy of large human colon carcinoma grafted in nude mice.

During one week, beginning 18 days after transplantation, nude mice bearing human colon carcinoma ranging from 115 to 943 mm3 (mean 335 mm3) were treated by repeated intravenous injections of either iodine-131-(131I) labeled intact antibodies or 131I-labeled corresponding F(ab')2 fragments of a pool of four monoclonal antibodies (MAbs) directed against distinct epitopes of carcinoembryonic antigen (CEA). Complete tumor remission was observed in 8 of 10 mice after therapy with F(ab')2 and 6 of the animals survived 10 mo in good health. In contrast, after treatment with intact MAbs, tumors relapsed in 7 of 8 mice after remission periods of 1 to 3.5 mo despite the fact that body weight loss and depression of peripheral white blood cells, symptoms of radiation toxicity, and the calculated radiation doses for liver, spleen, bone, and blood were increased or equal in these animals as compared to mice treated with F(ab')2.

Factors associated with comorbidity patterns in full and partial PTSD: Findings from the PsyCoLaus study.

Subtypes of comorbid conditions and their associated trauma and clinical characteristics in full and partial PTSD were examined. Data from 289 subjects from the general population that met criteria for full or partial PTSD were analyzed. Latent class analyses (LCA) were performed to derive homogeneous patterns of DSM-IV Axis-I disorders and anti-social personality comorbid to PTSD. Logistic regression models were conducted to characterize these classes by trauma-related and clinical features. The LCA revealed three classes: (1) low comorbidity; (2) high comorbidity with primarily substance-related disorders and a higher proportion of males; and (3) more severe PTSD-symptomatology and higher comorbid anxiety disorders and depression, almost entirely represented by females. Exposure to sexual abuse was more likely in the substance-dependent class and contributed strongly to the distinction between classes. Affective disorders tended to precede the onset of PTSD in the substance-dependent class, whereas phobias were more likely to follow PTSD in the depressed-anxious class. Posttrauma onset of alcohol use disorders in the substance dependent class confirmed the self-medication hypothesis. The three classes of comorbidity and their sequence of onset with PTSD suggest different mechanisms involved in their development. Our findings suggest that PTSD-related comorbidity subtypes also apply to individuals with partial PTSD.

Identification of psychological dysfunctions and eating disorders in obese women seeking weight loss: cross-sectional study.

Objective. The aim of this study is to analyse associations between eating behaviour and psychological dysfunctions in treatment-seeking obese patients and identify parameters for the development of diagnostic tools with regard to eating and psychological disorders. Design and Methods. Cross-sectional data were analysed from 138 obese women. Bulimic Investigatory Test of Edinburgh and Eating Disorder Inventory-2 assessed eating behaviours. Beck Depression Inventory II, Spielberger State-Trait Anxiety Inventory, form Y, Rathus Assertiveness Schedule, and Marks and Mathews Fear Questionnaire assessed psychological profile. Results. 61% of patients showed moderate or major depressive symptoms and 77% showed symptoms of anxiety. Half of the participants presented with a low degree of assertiveness. No correlation was found between psychological profile and age or anthropometric measurements. The prevalence and severity of depression, anxiety, and assertiveness increased with the degree of eating disorders. The feeling of ineffectiveness explained a large degree of score variance. It explained 30 to 50% of the variability of assertiveness, phobias, anxiety, and depression. Conclusion. Psychological dysfunctions had a high prevalence and their severity is correlated with degree of eating disorders. The feeling of ineffectiveness constitutes the major predictor of the psychological profile and could open new ways to develop screening tools.

Care complexity, mood, and quality of life in liver pre-transplant patients.

RATIONALE: This study was intended to document the frequency of care complexity in liver transplant candidates, and its association with mood disturbance and poor health-related quality of life (HRQoL). METHODS: Consecutive patients fulfilling inclusion criteria, recruited in three European hospitals, were assessed with INTERMED, a reliable and valid method for the early assessment of bio-psychosocial health risks and needs. Blind to the results, they were also assessed with the Hospital Anxiety and Depression Scale (HADS). HRQoL was documented with the EuroQol and the SF36. Statistical analysis included multivariate and multilevel techniques. RESULTS: Among patients fulfilling inclusion criteria, 60 patients (75.9%) completed the protocol and 38.3% of them were identified as "complex" by INTERMED, but significant between-center differences were found. In support of the working hypothesis, INTERMED scores were significantly associated with all measures of both the SF36 and the EuroQol, and also with the HADS. A one point increase in the INTERMED score results in a reduction in 0.93 points in EuroQol and a 20% increase in HADS score. CONCLUSIONS: INTERMED-measured case complexity is frequent in liver transplant candidates but varies widely between centers. The use of this method captures in one instrument multiple domains of patient status, including mood disturbances and reduced HRQoL.

Flux and composition of settling particles across the continental margin of the Gulf of Lion: the role of dense shelf water cascading

Settling particles were collected using sediment traps deployed along three transects in the Lacaze-Duthiers and Cap de Creus canyons and the adjacent southern open slope from October 2005 to October 2006. The settling material was analyzed to obtain total mass fluxes and main constituent contents (organic matter, opal, calcium carbonate, and siliciclastics). Cascades of dense shelf water from the continental shelf edge to the lower continental slope occurred from January to March 2006. They were traced through strong negative near-bottom temperature anomalies and increased current speeds, and generated two intense pulses of mass fluxes in January and March 2006. This oceanographic phenomenon appeared as the major physical forcing of settling particles at almost all stations, and caused both high seasonal variability in mass fluxes and important qualitative changes in settling material. Fluxes during the dense shelf water cascading (DSWC) event ranged from 90.1 g m(-2) d(-1) at the middle Cap de Creus canyon (1000 m) to 3.2 g m(-2) d(-1) at the canyon mouth (1900 m). Fractions of organic matter, opal and calcium carbonate components increased seaward, thus diminishing the siliciclastic fraction. Temporal variability of the major components was larger in the canyon mouth and open slope sites, due to the mixed impact of dense shelf water cascading processes and the pelagic biological production. Results indicate that the cascading event remobilized and homogenized large amounts of material down canyon and southwardly along the continental slope contributing to a better understanding of the off-shelf particle transport and the internal dynamics of DSWC events.

Early dyadic patterns of mother-infant interactions and outcomes of prematurity at 18 months.

OBJECTIVE: With the increased survival of very preterm infants, there is a growing concern for their developmental and socioemotional outcomes. The quality of the early mother-infant relationship has been noted as 1 of the factors that may exacerbate or soften the potentially adverse impact of preterm birth, particularly concerning the infant's later competencies and development. The first purpose of the study was to identify at 6 months of corrected age whether there were specific dyadic mother-infant patterns of interaction in preterm as compared with term mother-infant dyads. The second purpose was to examine the potential impact of these dyadic patterns on the infant's behavioral and developmental outcomes at 18 months of corrected age. METHODS: During a 12-month period (January-December 1998), all preterm infants who were <34 weeks of gestational age and hospitalized at the NICU of the Lausanne University Hospital were considered for inclusion in this longitudinal prospective follow-up study. Control healthy term infants were recruited during the same period from the maternity ward of our hospital. Mother-infant dyads with preterm infants (n = 47) and term infants (n = 25) were assessed at 6 months of corrected age during a mother-infant play interaction and coded according to the Care Index. This instrument evaluates the mother's interactional behavior according to 3 scales (sensitivity, control, and unresponsiveness) and the child's interactional behavior according to 4 scales (cooperation, compliance, difficult, and passivity). At 18 months, behavioral outcomes of the children were assessed on the basis of a semistructured interview of the mother, the Symptom Check List. The Symptom Check List explores 4 groups of behavioral symptoms: sleeping problems, eating problems, psychosomatic symptoms, and behavioral and emotional disorders. At the same age, developmental outcomes were evaluated using the Griffiths Developmental Scales. Five areas were evaluated: locomotor, personal-social, hearing and speech, eye-hand coordination, and performance. RESULTS: Among the possible dyadic patterns of interaction, 2 patterns emerge recurrently in mother-infant preterm dyads: a "cooperative pattern" with a sensitive mother and a cooperative-responsive infant (28%) and a "controlling pattern" with a controlling mother and a compulsive-compliant infant (28%). The remaining 44% form a heterogeneous group that gathers all of the other preterm dyads and is composed of 1 sensitive mother-passive infant; 10 controlling mothers with a cooperative, difficult, or passive infant; and 10 unresponsive mothers with a cooperative, difficult, or passive infant. Among the term control subjects, 68% of the dyads are categorized as cooperative pattern dyads, 12% as controlling pattern dyads, and the 20% remaining as heterogeneous dyads. At 18 months, preterm infants of cooperative pattern dyads have similar outcomes as the term control infants. Preterm infants of controlling pattern dyads have significantly fewer positive outcomes as compared with preterm infants of cooperative pattern dyads, as well as compared with term control infants. They display significantly more behavioral symptoms than term infants, including more eating problems than term infants as well as infants from cooperative preterm dyads. Infants of the controlling preterm dyads do not differ significantly for the total development quotient but have worse personal-social development than term infants and worse hearing-speech development than infants from cooperative preterm dyads. The preterm infants of the heterogeneous group have outcomes that can be considered as intermediate with no significant differences compared with preterm infants from the cooperative pattern or the controlling pattern dyads. CONCLUSION: Among mother-preterm infant dyads, we identified 2 specific patterns of interaction that could play either a protective (cooperative pattern) or a risk-precipitating (controlling pattern) role on developmental and behavioral outcome, independent of perinatal risk factors and of the family's socioeconomic background. The controlling pattern is much more prevalent among preterm than term dyads and is related to a less favorable infant outcome. However, the cooperative pattern still represents almost 30% of the preterm dyads, with infants' outcome comparable to the ones of term infants. These results point out the impact of the quality of mother-infant relationship on the infant's outcome. The most important clinical implication should be to support a healthy parent-infant relationship already in the NICU but also in the first months of the infant's life. Early individualized family-based interventions during neonatal hospitalization and transition to home have been shown to reduce maternal stress and depression and increase maternal self-esteem and to improve positive early parent-preterm infant interactions.
