Crying and Health: Popular and Scientific Conceptions

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

Music and lyric characteristics of popular Dutch funeral songs

This study compared the characteristics of 150 songs (Dutch lyrics, N = 47, English lyrics, N = 103), popular at Dutch funerals, to an equal number of non-funeral songs. The variables explored included those linked with the music (valence, energy, danceability, acousticness, key, and tempo); and lyrics, namely: linguistics-related (first-person singular/plural, second-person pronouns; past, present, future tense; expressed emotion (positive, negative words, and the discrete emotional categories anger, anxiety, sadness); and category words (those relating to family, friends, death, religion). Funeral music was lower in valence, energy, and danceability and higher in acousticness than non-funeral music. Furthermore, English funeral music lyrics contained more second-person pronouns and were more future-focused than comparison songs. Funeral lyrics were not particularly negative, but English texts contained more words relating to sadness. In conclusion, funeral music differs in severable notable respects from general popular songs that may reflect the special purpose of this music

A Comparison of Music Characteristics of Funeral Music from Croatia, the Netherlands, and the United Kingdom

Music forms an integral and essential part of funeral rituals worldwide, but has to date received little systematic research attention. Recent investigations into funeral music used in the Netherlands showed that it is lower in tempo and valence, less energetic, and more acoustic than popular music. Funeral music is also often in a major mode. The present study sought to replicate these findings for a Dutch (NL) funeral music sample and to expand upon previous knowledge by investigating the audio features provided by Spotify, namely: valence, energy, tempo, acousticness, instrumentalness, mode, and danceability for funeral music samples from Croatia (HR) and the United Kingdom (UK). First, values of music characteristics for funeral music used in HR, N = 388 pieces, NL, N = 500 pieces, and UK, N = 439 pieces, were compared to values of popular control music from each country separately. Previous findings were replicated: for HR, NL, and UK, funeral music displayed a similar pattern as described above. Second, the values of Spotify audio features for funeral music were compared between countries. Analyses revealed significant differences between NL/UK and HR, namely lower valence and energy and higher acousticness (only HR-UK) and instrumentalness for NL/UK compared to HR. Effect sizes were, however, small and are likely due to differences in music selections. These results suggest that, even though there is much diversity in music pieces and songs, funeral music within and across these European countries is more alike than different in terms of its audio characteristics

Pictorial Representation of Illness and Self Measure Revised II (PRISM-RII) – a novel method to assess perceived burden of illness in diabetes patients

<p>Abstract</p> <p>Background</p> <p>The Pictorial Representation of Illness and Self Measure (PRISM) has been introduced as a visual measure of suffering. We explored the validity of a revised version, the PRISM-RII, in diabetes patients as part of the annual review.</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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 (<it>r </it>= -.25; <it>p </it>< .01). Convergent validity of PRISM-RII was demonstrated by significant correlations between IPM and PAID (<it>r </it>= 0.50; <it>p </it>< 0.01), WHO-5 (<it>r </it>= -.26; <it>p </it>< 0.01) and SQ (<it>r </it>= 0.36; <it>p </it>< 0.01). SIS showed only significant correlations with PAID (<it>r </it>= -0.28; <it>p </it>< 0.01) and SQ (<it>r </it>= -0.22; <it>p </it>< 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.</p> <p>Conclusion</p> <p>PRISM-RII appears a promising additional tool to assess the psychological burden of diabetes.</p

Modulation of immune response to rDNA hepatitis B vaccination by psychological stress

In a previous study it was shown that antibody formation after vaccination with a low-dose recombinant DNA (rDNA) hepatitis B vaccine was negatively influenced by psychological stress. The present study was designed to assess whether the same inverse relation between HBs-antibody levels and psychological stress could be observed, while administering the standard, and thus higher, dose of vaccine. Volunteers (n = 68) scoring extremely low or high on a combination of questionnaires measuring daily problems and psychoneurotic symptoms were selected for participation. Antibody levels were determined 2, 6, and 7 months after the first vaccination. Questionnaires were completed before entering the study and at month 6. In contrast to the previous study, psychological stress was not found to be related to the antibody levels at any timepoint. These results suggest that, under certain conditions, stress-induced immunomodulation in vivo might be dependent on antigen dose

Paroxetine reduces crying in young women watching emotional movies

Rationale: Crying is a unique human emotional reaction that has not received much attention from researchers. Little is known about its underlying neurobiological mechanisms, although there is some indirect evidence suggesting the involvement of central serotonin. Objectives: We examined the acute effects of the administration of 20 mg paroxetine on the crying of young, healthy females in response to emotional movies. Methods: We applied a double-blind, crossover randomised design with 25 healthy young females as study participants. On separate days, they received either paroxetine or placebo and were exposed to one of two emotional movies: 'Once Were Warriors' and 'Brian's Song'. Crying was assessed by self-report. In addition, the reactions to emotional International Affective Picture System (IAPS) pictures and mood were measured. Results: Paroxetine had a significant inhibitory effect on crying. During both films, the paroxetine group cried significantly less than the placebo group. In contrast, no effects on mood and only minor effects on the reaction to the IAPS pictures were observed. Conclusions: A single dose of paroxetine inhibits emotional crying significantly. It is not sure what the underlying mechanism is. However, since there was no effect on mood and only minor effects on the response to emotional pictures, we postulate that paroxetine mainly acts on the physiological processes involved in the crying response

Cross-validated stepwise regression for identification of novel non-nucleoside reverse transcriptase inhibitor resistance associated mutations

<p>Abstract</p> <p>Background</p> <p>Linear regression models are used to quantitatively predict drug resistance, the phenotype, from the HIV-1 viral genotype. As new antiretroviral drugs become available, new resistance pathways emerge and the number of resistance associated mutations continues to increase. To accurately identify which drug options are left, the main goal of the modeling has been to maximize predictivity and not interpretability. However, we originally selected linear regression as the preferred method for its transparency as opposed to other techniques such as neural networks. Here, we apply a method to lower the complexity of these phenotype prediction models using a 3-fold cross-validated selection of mutations.</p> <p>Results</p> <p>Compared to standard stepwise regression we were able to reduce the number of mutations in the reverse transcriptase (RT) inhibitor models as well as the number of interaction terms accounting for synergistic and antagonistic effects. This reduction in complexity was most significant for the non-nucleoside reverse transcriptase inhibitor (NNRTI) models, while maintaining prediction accuracy and retaining virtually all known resistance associated mutations as first order terms in the models. Furthermore, for etravirine (ETR) a better performance was seen on two years of unseen data. By analyzing the phenotype prediction models we identified a list of forty novel NNRTI mutations, putatively associated with resistance. The resistance association of novel variants at known NNRTI resistance positions: 100, 101, 181, 190, 221 and of mutations at positions not previously linked with NNRTI resistance: 102, 139, 219, 241, 376 and 382 was confirmed by phenotyping site-directed mutants.</p> <p>Conclusions</p> <p>We successfully identified and validated novel NNRTI resistance associated mutations by developing parsimonious resistance prediction models in which repeated cross-validation within the stepwise regression was applied. Our model selection technique is computationally feasible for large data sets and provides an approach to the continued identification of resistance-causing mutations.</p

Personality, psychological stress, and self-reported influenza symptomatology

<p>Abstract</p> <p>Background</p> <p>Psychological stress and negative mood have been related to increased vulnerability to influenza-like illness (ILI). This prospective study re-evaluated the predictive value of perceived stress for self-reported ILI. We additionally explored the role of the negative affectivity and social inhibition traits.</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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).</p> <p>Conclusion</p> <p>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.</p
