Pain, frailty and comorbidity on older men: the CHAMP study.

Intrusive pain is likely to have a serious impact on older people with limited ability to respond to additional stressors. Frailty is conceptualised as a functional and biological pattern of decline accumulating across multiple physiological systems, resulting in a decreased capacity to respond to additional stressors. We explored the relationship between intrusive pain, frailty and comorbid burden in 1705 community-dwelling men aged 70 or more who participated in the baseline phase of the CHAMP study, a large epidemiological study of healthy ageing based in Sydney, Australia. 9.4% of men in the study were frail (according to the commonly-used Cardiovascular Health Study frailty criteria).Using a combination of self-report and clinical measures, we found an association between frailty and intrusive pain that remained after accounting for demographic characteristics, number of comorbidities, self-reported depressed mood and arthritis (adjusted odds ratio 1.7 (95% confidence interval (CI) 1.1-2.7), p=0.0149). The finding that adjusting for depressed mood, but not a history of arthritis, attenuated the relationship between frailty and intrusive pain points to a key role for central mechanisms. Additionally, men with the highest overall health burden (frail plus high comorbid burden) were most likely to report intrusive pain (adjusted odds ratio 3.0 (95% CI 1.6-5.5), p=0.0004). These findings provide support for the concept that intrusive pain is an important challenge for older men with limited capacity to respond to additional physical stressors. To our knowledge, this is the first study to explore specifically the relationship between pain and frailty.

Gender-related psychological and behavioural correlates of pubertal timing in a national sample of Swiss adolescents.

The potential consequences of early and late puberty on the psychological and behavioural development of the adolescent are not well known. This paper presents focused analyses from the Swiss SMASH study, a self-administered questionnaire survey conducted among a representative sample of 7488 adolescents from 16 to 20 years old. Data from participants reporting early or late timing of puberty were compared with those reporting average timing of maturation. Early maturing girls reported a higher rate of dissatisfaction with body image (OR=1.32) and functional symptoms (OR=1.52) and reported engaging in sexual activity more often (OR=1.93). Early maturing boys reported engaging in exploratory behaviours (sexual intercourse, legal and illegal substance use) at a significantly higher rate (OR varying between 1.4 and 1.99). Both early and late maturing boys reported higher rates of dysfunctional eating patterns (OR=1.59 and 1.38, respectively), victimisation (OR=1.61 and 1.37, respectively) and depressive symptoms (OR=2.11 and 1.53, respectively). Clinicians should take into account the pubertal stage of their patients and provide them, as well as their parents, with appropriate counselling in the field of mental health and health behaviour.

Termination of pregnancy among teenagers - why more surgical terminations?

Introduction: In 2012, a study by K. Chatziioannidou and S-C. Renteria showed that teenagers chose to undergo a surgical termination of pregnancy (TOP) more often than a medical TOP (mifepristone followed by misoprostol) when they decided to terminate a pregnancy. It also showed that the teenagers' choice for a medical versus surgical method is inversely proportional to the adults' choice although the efficiency of the medical method showed even better results for teenagers than for adults. According to the hypothesis made, the reasons for this choice might be influenced by the following facts: (i) the belated call to make an appointment, the medical procedure not being available after 9 weeks of gestation; (ii) the imperative request for confidentiality; (iii) the beliefs and subjective appreciation of the medical staff. Objectives: The aim of this retrospective and qualitative study is to analyse the reasons why, in case of a TOP, teenagers chose the surgical method more often than their adult counterparts. Material: (i) All teenagers who were admitted for an abortive procedure during 2011 in the in- or outpatient ward. (ii) The professional team (midwives and sexual and reproductive counsellors) in charge in the case of a TOP request. Methods: The information about the patient's history and the biopsycho- social data was retrieved from the patient files filled out by midwives and sexual and reproductive health counsellors during the first appointment for a TOP request or during its process. The professionals' appreciation was evaluated by means of a semi-structured questionnaire. Results: Concerning the choice of the method for a pregnancy termination, the results of our research show that: (i) Out of 47 teenagers, 27 chose the surgical method and 17 the medical method. (ii) Three had a second trimester abortion (which includes use of the medical method). (iii) Fifteen teenagers out of the 27 who chose a surgical method consulted between the 9th and 14th weeks of amenorrhoea and therefore did not have any other choice. The reasons for their 'late arrival' will be explained in detail. The 12 teenagers who arrived before the 8th week of amenorrhoea and chose to undertake abortion by suction & curettage under general anaesthesia did it for the following reasons: (i) Four were afraid of bleeding and pain. (ii) Five thought that the organisation of the surgical procedure was easier. (iii) Two did not trust the abortion pill. (iv) One was taken to her mother's gynaecologist where she had a D&C. Confidentiality was requested nine times out of 27 when choosing the surgical method, and six times out of 17 when choosing the medical method. Therefore, although confidentiality concerns a third of the teenagers' pregnancy termination requests, it does not seem to be a significant element for the choice of the method. As for the subjective appreciation of the professionals, the first results of the discussions seem to show that teenagers were reluctant or resistant towards the medical method. Conclusion: This study shows that the reasons why teenagers still prefer the use of the surgical over the medical method compared to adults, seem to include the late request for an appointment, fear of pain and bleeding and organisational issues. Confidentiality does not seem to greatly influence the teenagers' choice. Nonetheless, medical professionals seem to favour the suction curettage procedure performed under anesthesia because they associate young age with vulnerability and psychological frailty and consequently diminished ability to cope with pain and emotional distress during the medical procedures.

The Effects of Multifactorial Fall Prevention on the Psychological Risk Factors of Falling

Psychological factors, such as depression or depressive symptoms and fear of falling are linked to falls among the aged. According to previous studies, they may increase the risk of falls and injurious falls. In addition, depression or a high amount of depressive symptoms and fear of falling may hinder participation in preventive activities. Despite the severe consequences of both conditions and their high prevalence among the aged, they have rarely been studied in the context of fall prevention. The study aimed to assess the effects of multifactorial fall prevention on the psychological risk factors of falling (depressive symptoms and fear of falling) among the community-dwelling aged at increased risk of falling. In addition, it aimed to determine factors predicting high adherence to preventive activities. Volunteers aged 65 or over, who had fallen during the year previous to randomisation were recruited. Participants (n=591) were randomised into an intervention or a control group. The intervention group received a multifactorial fall prevention programme including geriatric assessment, individual guidance on fall and fracture prevention, group- and home-based physical exercise, psychosocial group activities, lectures and home hazards assessment. The control group had a one-time counselling on fall and fracture prevention. The data on psychological risk factors of falling were collected by self-rated questionnaires. Multifactorial fall prevention was not effective in reducing depressive symptoms or fear of falling compared to one-time counselling in the total sample. However, in subgroup analyses, depressive symptoms reduced statistically significantly more among the men and older participants of the intervention group compared to the control group. Female gender, high physical and cognitive abilities and low self-perceived probability of falling were independent predictors of higher adherence in organised activities. In conclusion, few psychological benefits were gained during this multifactorial fall prevention trial. More attention should be focused on adherence, especially among the aged with functional disabilities.

The INTERMED questionnaire for predicting return to work after a multidisciplinary rehabilitation program for chronic low back pain.

OBJECTIVES: To evaluate the performance of the INTERMED questionnaire score, alone or combined with other criteria, in predicting return to work after a multidisciplinary rehabilitation program in patients with non-specific chronic low back pain. METHODS: The INTERMED questionnaire is a biopsychosocial assessment and clinical classification tool that separates heterogeneous populations into subgroups according to case complexity. We studied 88 patients with chronic low back pain who followed an intensive multidisciplinary rehabilitation program on an outpatient basis. Before the program, we recorded the INTERMED score, radiological abnormalities, subjective pain severity, and sick leave duration. Associations between these variables and return to full-time work within 3 months after the end of the program were evaluated using one-sided Fisher tests and univariate logistic regression followed by multivariate logistic regression. RESULTS: The univariate analysis showed a significant association between the INTERMED score and return to work (P<0.001; odds ratio, 0.90; 95% confidence interval, 0.86-0.96). In the multivariate analysis, prediction was best when the INTERMED score and sick leave duration were used in combination (P=0.03; odds ratio, 0.48; 95% confidence interval, 0.25-0.93). CONCLUSION: The INTERMED questionnaire is useful for evaluating patients with chronic low back pain. It could be used to improve the selection of patients for intensive multidisciplinary programs, thereby improving the quality of care, while reducing healthcare costs.

La thrombose de varicocèle : une étiologie rare de douleur testiculaire [Varicocele thrombosis: a rare etiology of testicular pain]

Acute testicular pain is frequent in urology. If torsion of the spermatic cord and orchiepididymitis are usual, varicocele thrombosis is an unusual clinical entity we reported.

Cellules gliales et douleur chronique: du laboratoire a l'espoir clinique [Glial cells and chronic pain: from the laboratory to clinical hope].

Despite their high prevalence, associated disability and seemingly rich pharmacopeia, the various forms of chronic pain remain frequently intractable. The past decade witnessed the rise of a concept stating that non-neuronal cells of the central nervous system, astrocytes and microglia, are crucial elements in pathological pain. This review gathers and summarizes the experimental data underpinning this theory in animal models and addresses their pertinence in humans. The potential opportunities and constraints of glial inhibition are exposed and compared to more moderate strategies of selective modulation. This therapeutic hope is particularly highlighted in our discussion of the first completed clinical trials employing glial inhibitors in the treatment of chronic pain.

Traitement de la douleur chronique: rôle de la stimulation transcrânienne du cortex moteur [Treatment of chronic pain: transcranial stimulation of the motor cortex?].

Chronic pain refractory to medical therapy poses a therapeutic challenge. The repetitive Transcranial Magnetic Stimulation (rTMS) and transcranial Direct Current Stimulation (tDCS) modulate brain activity offering a new approach. Current evidence suggests a potential therapeutic efficacy of motor cortex stimulation for the treatment of pain, but does not (yet) support their recommendation for clinical practice. These methods allow to deepen our knowledge in the pathophysiology of chronic pain while providing new therapeutic approaches.

Neuroendocrine regulation and central dopamine (DA) systems in physical and psychological stress

Physical and psychological stress cause different patterns of changes in the fluorescence intensity of nigral and tuberoinfundibular DA neurons which point to changes in neuronal activity. In order to investigate possible interactions between alpha-MSH (alpha-melanotropin) and DA systems in stress, systemic and intraventricular injections of antiserum against alpha-MSH were made. The functional state of DA neurons was assessed by histochemical microfluorimetry and hormone levels were measured by radioimmunossay. Antiserum against alpha-MSH was found to affect the functional state of DA neurons, but only thorugh the intravenous route. Under physical stress i.v. injection of antiserum against alpha-MSH was accompanied by elevated levels of activity of the DA neurons of the substantia nigra. An intraventricular injection of the same antiserum was ineffective. In psychological stress, an effect was again seen only after intravenous injection of antiserum against alpha-MSH. In this situation, the activity in DA cell groups of the substantia nigra, ventral tegmental area and tubero-infundibular system was increased after antiserum injection. Possible influences from manipulations were checked; certain effects which depended upon experimental situation were noted. Our data suggest a modulatory influence of circulating alpha-MSH on the functional state of central DA systems.

Personality traits, behavioral and psychological symptoms and cognitive decline in patients at an early stage of Alzheimer's disease

The aim of this doctoral thesis was to study personality characteristics of patients at an early stage of Alzheimer's disease (AD), and more specifically to describe personality and its changes over time, and to explore its possible links with psychological and symptoms (BPS) and cognitive level. The results were compared to those of a group of participants without cognitive disorder through three empirical studies. In the first study, the findings showed significant personality changes that follow a specific trend in the clinical group. The profil of personality changes showed an increase in Neuroticism and a decrease in Extraversion, Openess to experiences, and Conscientiousness over time. The second study highlighted that personality and BPS occur early in the cours of AD. Recognizing them as possible precoce signs of neurodegeneration may prove to be a key factor for early detection and intervention. In the third study, a significant association between personality changes and cognitive status was observed in the patients with incipient AD. Thus, changes in Neuroticism and Conscientiousness were linked with cognitive deterioration, whereas decreased Openness to experiences and Conscientiousness over time predicted loss of independence in daily functioning. Other well-known factors such as age, education level or civil status were taken into account to predict cognitive decline. The three studies suggested five important implications: (1) cost-effective screening should take into account premorbid and specific personality changes; (2) psycho-educative interventions should provide information on the possible personality changes and BPS that may occur at the beginning of the disease; (3) using personality traits alongside other variables in the future studies on prevention might help to better understand AD's etiology; (4) individual treatment plans (psychotherapeutic, social, and pharmacological) might be adapted to the specific changes in personality profiles; (5) more researches are needed to study the impact of social-cultural and lifestyle variables on the development of AD.

Efficiency of coronary artery disease screening guidelines in asymptomatic and atypical chest pain type 2 diabetic patients

RESUME Objectifs. Évaluer la prévalence de maladie coronarienne chez les patients diabétiques de type 2 asymptomatiques ou avec angor atypique selon les recommandations américaines de l'American Diabetes Association et de l'American College of Cardiology. Méthodes. Cent cinquante-quatre patients diabétiques de type 2 asymptomatiques ou avec angor atypique et présentant au minimum 2 facteurs de risque cardio-vasculaires additionnels ont été dépistés par échocardiographie de stress (71%, n=109), scintigraphie myocardique de perfusion (26%, n=40) ou l'association des 2 examens (3%, n=5). Résultats. L'échocardiographie de stress s'est révélée positive chez 16 patients (14%) et 14 ont eu une coronarographie révélant des sténoses significatives chez 12 (86%). La scintigraphie myocardique de perfusion était positive chez 16 patients (36%). Huit patients ont eu une coronarographie et 4 (50%) présentaient des sténoses significatives. Au total, 31 patients (20%) ont montré des signes d'ischémie lors de l'examen non-invasif et 15 (10%) ont présenté des sténoses significatives à la coronarographie. Les facteurs prédictifs indépendants de la maladie coronarienne étaient le tabagisme (OR 6.5, p=0.05), la microalbuminurie (OR 3.9, p=0.03), ainsi que les souffles fémoraux (OR 17.1, p=0.008). Conclusions. En suivant les recommandations américaines, un patient sur cinq présentait une ischémie lors des examens non-invasifs, tandis que 1 sur 10 avait des sténoses significatives à la coronarographie. L'analyse multivariée suggère que des marqueurs des complications micro- et macro-vasculaires en combinaison avec des facteurs de risque cardio-vasculaire classiques pourraient améliorer le pouvoir diagnostic de ces recommandations. SUMMARY Aims. We evaluated the prevalence of coronary artery disease in asymptomatic and atypical chest pain type 2 diabetic patients according to the American Diabetes Association and American College of Cardiology guidelines. Methods. Asymptomatic or atypical chest pain type 2 diabetic patients (n=154), with at least two additional cardiovascular risk factors, were screened for coronary artery disease using stress echocardiography (71%, n=109), myocardial perfusion imaging (26%, n=40) or both (3%, n=5). Results. Stress echocardiography was positive in 16 patients (14%) and 14 had a coronary angiography, revealing significant stenoses in 12 (86%). Myocardial perfusion imaging was positive in 16 patients (36%). Eight patients underwent angiography and 4 (50%) presented significant stenoses. Overall, 31 patients (20%) demonstrated signs of ischemia on non-invasive tests and 15 (10%) presented significant stenoses on coronary angiography. Independent predictors of coronary artery disease were smoking (OR 6.5, p=0.05), microalbuminuria (OR 3.9, p=0.03) and femoral murmur (OR 17.1, p=0.008). Conclusions. Following the guidelines, one in five diabetic patient presented ischemia on noninvasive tests, while one in ten presented significant coronary stenoses. Multivariate analysis suggests that adding markers of micro- and macro-vascular complications to classical cardiovascular risk factors may enhance the diagnostic efficiency of the guidelines.

A meta-analysis of acupuncture for chronic pain.

Results of 14 randomized controlled trials of acupuncture for chronic pain were pooled in a meta-analysis and analysed in three subgroups according to site of pain; and in two subgroups each according to type to trial, type of treatment, type of control, 'blindness' of participating agents, trial size, and type of journal in which results were published. While few individual trials had statistically significant results, pooled results of many subgroups attained statistical significance in favour of acupuncture. Various potential sources of bias, including problems with blindness, precluded a conclusive finding although most results apparently favoured acupuncture.
