Personality, psychological stress, and self-reported influenza symptomatology
Kim GE Smolderen, Ad JJM Vingerhoets, Marcel A Croon, Johan Denollet
BMC Public Health , 2007, DOI: 10.1186/1471-2458-7-339
Abstract: In this study, 5,404 respondents from the general population were assessed in terms of perceived stress, personality, and control variables (vaccination, vitamin use, exercise, etc.). ILI were registered weekly using self-report measures during a follow-up period of four weeks.Multivariable logistic regression analysis on ILI was performed to test the predictive power of stress and personality. In this model, negative affectivity (OR = 1.05, p = 0.009), social inhibition (OR = 0.97, p = 0.011), and perceived stress (OR = 1.03, p = 0.048) predicted ILI reporting. Having a history of asthma (OR = 2.33, p = < 0.0001) was also associated with ILI reporting. Older age was associated with less self-reported ILI (OR = 0.98, P = 0.017).Elderly and socially inhibited persons tend to report less ILI as compared to their younger and less socially inhibited counterparts. In contrast, asthma, trait negative affectivity, and perceived stress were associated with higher self-report of ILI. Our results demonstrate the importance of including trait markers in future studies examining the relation between stress and self-report symptom measures.Together with the emergence of the field of psychoneuroimmunology, a growing interest can be observed in the role of psychosocial variables in the development of infectious disease, including the common cold and influenza-like illness [1]. From an etiological point of view, it is clear that whereas the pathogen should be considered as a necessary but not sufficient (e.g., dependent on its virulence) factor, psychosocial factors are neither necessary nor sufficient. The latter factors are rather hypothesized to affect the vulnerability of the host, and in such way contributing to increased risk of infectious disease. Psychological stress, often conceptualized as the exposure to major stressful life events, daily hassles, and negative mood has been associated with increased vulnerability to infectious illness [2-6]. For example, Graham et al.[6]
Pictorial Representation of Illness and Self Measure Revised II (PRISM-RII) – a novel method to assess perceived burden of illness in diabetes patients
Sandor Klis, Ad JJM Vingerhoets, Maartje de Wit, Noortje Zandbelt, Frank J Snoek
Health and Quality of Life Outcomes , 2008, DOI: 10.1186/1477-7525-6-104
Abstract: Participants were 308 adult outpatients with either type 1 or type 2 diabetes. Measures: (1) the PRISM-RII, yielding Self-Illness Separation (SIS) and Illness Perception Measure (IPM); (2) the Problem Areas in Diabetes (PAID) scale, a measure of diabetes-related distress; (3) the WHO-5 Well-Being Index; (4) and a validation question on suffering (SQ). In addition, patients' complication status, comorbidity and glycemic control values(HbA1c) were recorded.Patients with complications did have marginally significant higher scores on IPM, compared to patients without complications. Type 2 patients had higher IPM scores than Type 1 patients. SIS and IPM showed low intercorrelation (r = -.25; p < .01). Convergent validity of PRISM-RII was demonstrated by significant correlations between IPM and PAID (r = 0.50; p < 0.01), WHO-5 (r = -.26; p < 0.01) and SQ (r = 0.36; p < 0.01). SIS showed only significant correlations with PAID (r = -0.28; p < 0.01) and SQ (r = -0.22; p < 0.01). Neither IPM nor SIS was significantly associated with HbA1c. The PRISM-RII appeared easy to use and facilitated discussion with care providers on coping with the burden of diabetes.PRISM-RII appears a promising additional tool to assess the psychological burden of diabetes.Living with a chronic disease like diabetes requires considerable psychological adjustment. Failure to adjust adequately to the disease may have negative consequences for the patient's quality of life, possibly resulting in suffering. An important outcome of this adjustment is the amount of suffering that a disease potentially causes. Although suffering is frequently mentioned in the medical literature, its definition and characteristics are often implied rather than defined. One definition that has been frequently cited is that of Cassell [1]: 'a state of severe distress associated with events that threaten the intactness of the person'. From this definition, it follows that the extent of suffering is not merely determined by the

BMC Pediatrics , 2012, DOI: 10.1186/1471-2431-12-76
Abstract: This study is a multi-center randomised controlled trial to evaluate the effectiveness of Video Interaction Guidance in parents of premature infants. In this study 210 newborn infants with their parents will be included: n?=?70 healthy term infants (>37?weeks GA), n?=?70 moderate term infants (32–37?weeks GA) which are recruited from maternity wards of 6 general hospitals and n?=?70 extremely preterm infants or very low birth weight infants (<32?weeks GA) recruited by the NICU of 2 specialized hospitals. The participating families will be divided into 3 groups: a reference group (i.e. full term infants and their parents, receiving care as usual), a control group (i.e. premature infants and their parents, receiving care as usual) and an intervention group (i.e. premature infants and their parents, receiving VIG). The data will be collected during the first six months after birth using observations of parent-infant interactions, questionnaires and semi-structured interviews. Primary outcomes are the quality of parental bonding and parent-infant interactive behaviour. Parental secondary outcomes are (posttraumatic) stress symptoms, depression, anxiety and feelings of anger and hostility. Infant secondary outcomes are behavioral aspects such as crying, eating, and sleeping.This is the first prospective study to empirically evaluate the effect of VIG in parents of premature infants. Family recruitment is expected to be completed in January 2012. First results should be available by 2012.NTR3423Each year, 2% to 9% of the newborns require specialised care in neonatal intensive care units (NICU). The majority are premature infants (born before 37?weeks of gestational age) who weigh less than 2500?g at birth. Modern medical technology has forced back the frontiers of viability so that a growing number of babies, even as young as 23 to 24?weeks gestation with weights as low as 500 gram, are currently surviving [1]. With the improved survival chance of preterm infants, there i
Crying and Health: Popular and Scientific Conceptions
Ad J .J. M. Vingerhoets,Lauren Bylsma
Psychological Topics , 2007,
Abstract: We summarize popular and pre-scientific conceptions of the relationship between crying, well-being and health, and we review the scientific literature on this topic. First, the focus is on whether crying brings relief and facilitates emotional recovery. Next, we discuss the evidence addressing whether crying or its chronic inhibition is associated with an increased risk of developing health problems. Finally, we address crying as a signal or symptom of disease. It is concluded that the question regarding whether crying brings relief has yielded seemingly contrasting findings, dependent on the design of the study. Concerning the second and third issues, there is a lack of sound studies. Little is known about the nature of the association between depression and crying. The evidence for a relationship between neurological disorders (in particular, stroke and multiple sclerosis) appears more convincing. There is also mainly anecdotal evidence of increased crying in a wide variety of health problems, which may reflect symptoms of disease, co-morbid depression, adjustment problems, or side effects of treatment. Some recent studies further suggest a positive effect of crying on health status in certain patient groups. More systematic and well-designed studies are needed to clarify the relationship between crying and health.
Does antioxidant therapy influence every aspect of quality of life?
Tomasz Stefaniak,Ad Vingerhoets,Zbigniew Sledzinski
World Journal of Gastroenterology , 2012, DOI: 10.3748/wjg.v18.i19.2441
Abstract: To present problems that might severely impact the conclusions drawn by the authors of an article on antioxidant treatment in chronic pancreatitis (World J Gastroenterol 2010; 16: 4066-4071). We analyzed and discussed this paper by Shah et al, and found that promising as it is, this study has some methodological shortcomings, such as: cross-sectional nature of the study, lack of initial evaluations of quality of life and regular follow-ups to determine the dynamics and real directions of changes in quality of life. We therefore concluded that the results of the study by Shah et al are biased and, although very promising, should not be considered as scientifically relevant.
Leisure Sickness: A Biopsychosocial Perspective
Guus L. Van Heck;,Ad J.J.M. Vingerhoets
Psychological Topics , 2007,
Abstract: Leisure and vacation are generally associated with feelings of relaxation and well-being. However, there is also evidence suggesting that some people feel particularly ill and develop symptoms especially during weekends and vacations. The focal points of this article are the exploration of the antecedents and consequences of this phenomenon, pointing out the need of systematic research on its prevalence, phenomenology, background, and the putative mechanisms involved. The paper concludes with a discussion of some possible effective interventions

Journal of Obesity , 2010, DOI: 10.1155/2010/231074
Abstract: Aim and Method. To examine in obese people the potential effectiveness of a six-week, two times weekly aquajogging program on body composition, fitness, health-related quality of life, and exercise beliefs. Fifteen otherwise healthy obese persons participated in a pilot study. Results. Total fat mass and waist circumference decreased 1.4 kg (=.03) and 3.1 cm (=.005), respectively. The distance in the Six-Minute Walk Test increased 41 meters (=.001). Three scales of the Impact of Weight on Quality of Life-Lite questionnaire improved: physical function (=.008), self-esteem (=.004), and public distress (=.04). Increased perceived exercise benefits (=.02) and decreased embarrassment (=.03) were observed. Conclusions. Aquajogging was associated with reduced body fat and waist circumference and improved aerobic fitness and quality of life. These findings suggest the usefulness of conducting a randomized controlled trial with long-term outcome assessments.
The role of 'confounding by indication' in assessing the effect of quality of care on disease outcomes in general practice: results of a case-control study

Abstract: Stroke patients (cases) and controls were recruited from the general practitioner's (GP) patient register, and an expert panel assessed the quality of care of cases and controls using guideline-based review criteria.A total of 86 patients was assessed. Compared to patients without shortcomings in preventive care, patients who received sub-optimal care appeared to have a lower risk of experiencing a stroke (OR 0.60; 95% CI 0.24 to 1.53). This result was partly explained by the presence of risk factors (6.1 per cases, 4.4 per control), as reflected by the finding that the OR came much closer to 1.00 after adjustment for the number of risk factors (OR 0.82; 95% CI 0.29 to 2.30). Patients with more risk factors for stroke had a lower risk of sub-optimal care (OR for the number of risk factors present 0.76; 95% CI 0.61 to 0.94). This finding represents a variant of 'confounding by indication', which could not be fully adjusted for due to incomplete information on risk factors for stroke.At present, inaccurate recording of patient and risk factor information by GPs seriously limits the potential use of a case-control method to assess the effect of guideline adherence on disease outcome in general practice. We conclude that studies on the effect of quality of care on disease outcomes, like other observational studies of intended treatment effect, should be designed and performed such that confounding by indication is minimized.There is a long tradition of studying at population level the quality of medical care provided to patients who died from conditions amenable to medical intervention. This type of study (so called 'in-depth' or 'audit' study), aims to identify deficiencies in medical care that may have contributed to death. It was first systematically carried out on maternal death, and later on other causes of avoidable death [1-4]. This method can be applied to other potentially avoidable conditions, e.g. those that could be avoided by appropriate preventive care. Th

Introduction Of the more than 1 billion overweight adults, at least 300 million are obese (Body Mass Index [BMI]?? 30?kg/ ) [1, 2]. Obesity increases the risk of chronic diseases, particularly cardiovascular disease [3–5], type II diabetes mellitus [6, 7], and osteoarthritis [8, 9] in adults. Quality of life is severely reduced in obese persons [10, 11], and it is related to the degree of overweight [12]. Both obesity and living a sedentary life have been associated independently with decreased quality of life [13] and stress regulation [14]. Physical exercise, combined with dietary adjustments, massages, and baths, has been recommended for obesity since Hippocrates (fourth century BC) [15]. Aerobic exercise produces less weight loss compared to caloric restriction programs [16]. Some recent studies, however, give evidence for weight loss, especially abdominal weight loss, as a result of exercise without caloric restriction [17–19]. Given the benefits for both physical and mental health [20], exercise has been widely recommended to reduce the health risks associated with overweight and obesity, even if the weight loss is minimal [19, 21, 22]. However, there is a substantial elevated risk of injuries in obese persons, especially sprains and strains [23]. Physical exercise in water is a possibility to try to increase physical and mental health of obese persons without the risk of injuries. Aerobic activities in water have been found to be effective to improve aerobic fitness [24], and the effect on body composition has been demonstrated to be similar to weight-bearing aerobic exercise on land [25]. Aquajogging is a specific form of
Evaluation of simplified dna extraction methods for EMM typing of group a streptococci
Jose JJM,Brahmadathan K
Indian Journal of Medical Microbiology , 2006,
Abstract: Simplified methods of DNA extraction for amplification and sequencing for emm typing of group A streptococci (GAS) can save valuable time and cost in resource crunch situations. To evaluate this, we compared two methods of DNA extraction directly from colonies with the standard CDC cell lysate method for emm typing of 50 GAS strains isolated from children with pharyngitis and impetigo. For this, GAS colonies were transferred into two sets of PCR tubes. One set was preheated at 94oC for two minutes in the thermal cycler and cooled while the other set was frozen overnight at -20oC and then thawed before adding the PCR mix. For the cell lysate method, cells were treated with mutanolysin and hyaluronidase before heating at 100oC for 10 minutes and cooling immediately as recommended in the CDC method. All 50 strains could be typed by sequencing the hyper variable region of the emm gene after amplification. The quality of sequences and the emm types identified were also identical. Our study shows that the two simplified DNA extraction methods directly from colonies can conveniently be used for typing a large number of GAS strains easily in relatively short time.
