Storylines of Family Medicine is a 12-part series of thematically linked essays with accompanying illustrations that explore the many dimensions of family medicine, as interpreted by individual family physicians and medical educators in the USA and elsewhere around the world. In 'V: ways of thinking-honing the therapeutic self', authors present the following sections: 'Reflective practice in action', 'The doctor as drug-Balint groups', 'Cultivating compassion', 'Towards a humanistic approach to doctoring', 'Intimacy in family medicine', 'The many faces of suffering', 'Transcending suffering' and 'The power of listening to stories.' May readers feel a deeper sense of their own therapeutic agency by reflecting on these essays.

Background: Limited knowledge exists regarding patients' denial of myocardial infarction (MI) before hospitalization for an MI. Objective: The aim of this study was to determine the prevalence and correlates of denial of MI in the prehospital phase of a confirmed MI. Methods: This secondary analysis included 166 hospitalized patients (mean [SD] age, 54.1 [10.5] years) who developed MI outside a healthcare facility and had high congruence between their experienced and expected symptoms. Measurements included the Denial subscale of the Brief COPE Inventory, the modified Response to Symptoms Questionnaire, and a Likert scale measuring perceived risk for MI. Patients who arrived at a hospital at least 1 hour after the onset of their symptoms were considered to have prolonged prehospital delay. Results: Despite their high symptom congruence, 77% of patients denied the possibility of having an MI before hospitalization. The lower denial group was characterized by cardiac history, whereas the higher denial group was distinguished by nonsmoking, a lower perceived risk of MI, less anxiety at symptom onset, and more concerns about seeking medical help. Compared with the lower denial group, patients in the higher denial group were more likely to underestimate the seriousness of their symptoms and delay seeking medical help. The higher denial group responded to symptoms in a more passive manner (eg, waiting), whereas the lower denial group showed a more problem-solving approach (eg, contacting emergency services). Conclusions: Denial of MI is highly prevalent in the prehospital phase and is negatively linked with cognitive, emotional, and behavioral responses to MI symptoms. [ABSTRACT FROM AUTHOR]

Background: Chronic pain often clusters in families, where parents and their offspring both experience chronic pain conditions. Young children of parents with irritable bowel syndrome (IBS) represent an at-risk group for the development of abdominal pain, disability, and excess health care visits in later childhood. Parental solicitous responses to children's expressions of discomfort and maternal modeling of their own illness behavior contribute to a greater focus on somatic sensations, leading to illness behaviors in children. This randomized controlled trial will test the effectiveness of an early preventive web-based psychosocial intervention (REACH)[TM] vs. an educational web-based safety comparison condition delivered to parents with IBS to alter parental responses and lead to improved child health and decreased health care costs. Methods: Parents with IBS who have children ages 4–7 years are recruited via community-based approaches (e.g., social media advertisements, school electronic distribution, research networks) and health care providers. The target sample is 460 parents randomized to REACH, a web-based social learning and cognitive behavior therapy (SLCBT) intervention or an educational web-based safety comparison condition (EC). Participants will be assessed at baseline, 6-week (immediate post-intervention), 6-month, 12-month, and 18-month follow-up periods (months post-completion of intervention). The primary outcome is change in parental solicitous/protective behaviors. Secondary outcomes include parent risk and protective factors, child health and symptom outcomes, and health care utilization and cost savings. Discussion: This study adapts a validated, parent-delivered intervention to treat chronic pain in children to a web-based application designed to prevent the development of chronic pain in very young, high-risk children. If successful, this strategy can both prevent adverse sequelae of this condition from developing as well as be widely accessible. Furthermore, the availability of a prevention model for parent training could result in significant short- and long-term health benefits across a broad spectrum of conditions.

Introduction: Longitudinal data on how acute respiratory illness (ARI) affects behavior, namely school or work participation, and nonpharmaceutical intervention (NPI) usage before and during the COVID-19 pandemic is limited. The authors assessed how ARIs and specific symptoms affected school, work, and health-related behaviors over time. Methods: From November 2019 to June 2021, participating households with children in King County, Washington, were remotely monitored for ARI symptoms weekly. Following ARIs, participants reported illness-related effects on school, work, and NPI use. Using logistic regression with generalized estimating equations, the authors examined associations between symptoms and behaviors. Results: Of 1,861 participants, 581 (31%) from 293 households reported 884 ARIs and completed one-week follow-up surveys. Compared with the prepandemic period, during the period of the pandemic pre–COVID-19 vaccine, ARI-related school (56% vs 10%, p

Background. Illness representations determine a patient's successful adaptation in the context of chronic somatic illness. Objective. The study had its purpose to investigate and compare the illness representations in the patients with acute leukemia and lymphoma. Study Participants. The study involved 109 respondents: 51 patients with acute leukemia aged 18 to 64 years (Mage = 35.12; SD = 12.90; 28 women) and 58 patients with lymphoma aged 19 to 64 years (Mage = 42.22; SD = 11.17; 41 women). Methods. The study implemented the following methods: “Illness Perception Questionnaire-Revised” (IPQ-R), “Health Anxiety Inventory” (HAI), “Cognitions About Body and Health Questionnaire” (CABAH), and the “Scale of Assessment of Illness Behavior” (SAIB). Descriptive statistics and group comparison methods (Student's t-test) were used to process quantitative data. Results. A comparative analysis of the data obtained showed that patients with acute leukemia have more difficulty in identifying the disease, were more certain about the negative impact of the disease and its unstable course, were more likely to overestimate symptom severity, and paid more attention to implementing treatment- and medication-related behaviors compared to patients with lymphomas. Conclusion. The main targets of psychological work with patients with acute leukemia are their ideas about the disease identity, its unstable course and negative consequences, their tendency to overestimate the symptom severity and underestimate the importance of preventive behavior associated with treatment and medication. Common targets of psychological work with patients with acute leukemia and lymphoma are their ideas about the short-term course of the disease and negative emotional experiences about their disease.

Background: Working despite feeling ill – presenteeism – is a widespread behavioral phenomenon. Previous research has shown that presenteeism is influenced by various work-related and personal factors. It's an illness behavior leading to a range of negative but also positive consequences. Due to coronavirus disease 2019 (COVID-19) pandemic, remote work has become the “new normal” for many employees. But so far, little is known about presenteeism in remote work. This study aims to investigate presenteeism in remote work by looking at the extent of remote presenteeism, differences to presenteeism in on-site work, and associated factors. Methods: A nationwide cross-sectional online survey was conducted in Germany with N = 233 participants. Data were analyzed using descriptive statistics, t-tests, and correlation analysis. Results: The results reveal that presenteeism is prevalent in remote work x̅ = 4.13 days (Md = 3; D = 2; s = 4.95). A low ability to detach from work (r = -.17; p = .005) and low supervisor support (r = -.14; p = .02) is associated with more remote presenteeism days. Remote working conditions seem to facilitate presenteeism. Conclusion: This study provides empirical insights into a subject area of great societal relevance. The results show that awareness should be raised for presenteeism in remote work. It should be regarded as a behavior that can be functional or dysfunctional, depending on the individual situation. Supervisor support and detachment should be fostered to help reduce dysfunctional presenteeism. Promotion of health literacy might help remote workers to decide on a health-oriented illness behavior. Further research is vital to analyze to what extent and under which circumstances presenteeism in remote work is (dys)functional and to derive clear recommendations.

Sleep study results were analyzed. Scores were summarized using medians and interquartile ranges and are compared using Wilcoxon rank sum tests.Results: Overall FM (n = 25), female n=23 male n=3 mean age, 57.48 years. OSA n=17 (68%) and 8 (32%) were not. The SF-MPQ Sensory sub-scale scores and the SF-MPQ overall scores differed significantly between patients with and without OSA. The SF-MPQ Sensory sub-scale scores were significantly lower for patients with OSA (p=0.03), as were SF-MPQ overall scores (p=0.04). SSAS overall scores and IBQ overall scores did not differ significantly by OSA diagnosis. Correlations of the different dimensions of IBQ with SSAS and mean number of diagnoses in FM and FM+OSA, mean number of diagnoses in problem list of SSAS ≤ 30 was 29.5, mean number of diagnoses in SSAS ≥ 30 was 34.9.Discussion: Developing a better understanding of the effects of OSA on pain perception in patients with FM is needed for improved health status. More research is needed to see if higher pain perception and SSAS score lead to increased health care utilization and to evaluate the relationship between untreated disordered sleeping and pain perception in patients with FM.Conclusion: Our findings highlight the need for more research to evaluate the relationship between treated and untreated disordered sleeping, pain perception, somatization and illness behavior in the health status of individuals with FM.Keywords: fibromyalgia, obstructive sleep apnea, pain perception, symptom amplification, illness behavior

BACKGROUND: The number of deaths, causes, and frequency measures are crucial in determining the health of a country's population. OBJECTIVE: The current study aimed to estimate deaths, causes of death, and their frequency for Saudi nationals in 2017. METHODS: In this descriptive study, we used data from the 2017 Population Characteristics Survey (n = 14,215,901) and performed secondary data analysis between November 2021 and February 2022. We used a total number of survey samples to compute the deaths. The cause of death was determined by dividing the total number of fatalities according to sex. We calculated the overall population-, administrative region-, and gender-wise percentages, rates per 1,000 people per year, the ratios for mortality, and their reasons. RESULTS: There were 58,915 (0.4%) total deaths, including 0.3% and 0.2% deaths among females and males, respectively. The illness was the most frequent cause of mortality (46.5% or 465 per 1,000 population/year), notably in women (52.5% or 525 per 1,000 population/year). The fatality rate was higher due to traffic accidents (a total of five in every female and four males in every female). CONCLUSION: In 2017, illness—especially in women—was the cause of death. Road car accidents had a high mortality rate, especially among males. Saudi Arabia has lower death rates than other Arab nations and high-, moderate-, and low-income nations. [ABSTRACT FROM AUTHOR]

Culture is a way of thinking that has changed from the past to the present and forms the identity of the society with its unique art, belief, customs and behaviors. In this respect, it includes all material and spiritual elements that are revealed, valued and shared in society. Culture guides the individual on how to perceive or behave. At this point, culture has an important point in the perception and explanation of the disease states faced by the individual. Culture has a decisive role in all stages such as catching the disease, experiencing the disease, carrying the roles of the disease, trying to cope with the disease, complaining about the disease. Therefore, in this study, it is aimed to examine the interaction between culture and disease theoretically. As a result of the study, it is seen that individuals try to have information on diseases according to culture and develop behaviors towards the disease. In this respect, it has been concluded that culture creates a placebo and nocebo effect. While the placebo effect is perceived as a healing power on individuals, it is seen that the nocebo effect creates a pathological condition on individuals. For this reason, it is important for health professionals to determine the source of the disease by considering the cultures of the individuals while providing health services.

This study aimed to determine the association between the level of acceptance of illness and medication adherence, metabolic control, and risk of diabetic foot in patients with diabetes. This descriptive study was conducted with 298 patients with diabetes. The questionnaire comprised the demographic characteristics of the patients, Modified Morisky Scale and the Acceptance of Illness Scale. The study data were collected by the researchers through direct interviews using the questionnaire. Acceptance of illness in patients with diabetes was statistically significantly higher in the group with a higher level of knowledge of medication adherence (p < 0.001). Moreover, the acceptance of illness had a statistically significant negative correlation with fasting plasma glucose (r = −0.198; p < 0.001) and glycated hemoglobin (r = −0.159; p = 0.006) levels in individuals with diabetes. Levels of acceptance of illness had a statistically significant association with the risk of diabetic foot (p < 0.01). The study found that the level of acceptance of illness was associated with the level of knowledge about medication adherence, metabolic control, and risk of diabetic foot in individuals with diabetes. It may be recommended to conduct clinical trials to determine the effect of evaluating the level of acceptance of the illness on diabetes management and to increase this level. • Diabetic foot is associated with inadequate knowledge and poor practices. • Acceptance of illness is crucial in the management of diabetes. • Nurses should evaluate the acceptance of the illness in individuals with diabetes.

Introduction: Illness denial pertains to medical patients who do not acknowledge the presence or severity of their disease or the need of treatment. Objective: This systematic review was performed to clarify the clinical role and manifestations of illness denial, its impact on health attitudes and behavior, as well as on short- and long-term outcomes in patients with medical disorders. Methods: The systematic search according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines was conducted on PubMed, Scopus, and Web of Science. Results: The initial search yielded a total of 14,098 articles; 176 studies met the criteria for inclusion. Illness denial appeared to be a relatively common condition affecting a wide spectrum of health attitudes and behavior. In some cases, it may help a person cope with various stages of illness and treatment. In other situations, it may determine delay in seeking treatment, impaired adherence, and reduced self-management, leading to adverse outcomes. The Diagnostic Criteria for Psychosomatic Research (DCPR) were found to set a useful severity threshold for the condition. An important clinical distinction can also be made based on the DCPR for illness denial, which require the assessment of whether the patient has been provided with an adequate appraisal of the medical situation. Conclusions: This systematic review indicates that patients with medical disorders experience and express illness denial in many forms and with varying degrees of severity. The findings suggest the need for a multidimensional assessment and provide challenging insights into the management of medical disorders. [ABSTRACT FROM AUTHOR]

Abstract Background Approximately 6.5 million adults have chronic heart failure (HF), the number one cause of 30-day hospital readmission. Managing HF and its symptoms is critical for patients. Hospitalization may impact patients’ perceptions of illness control, which can affect illness management. However, how hospital readmissions are perceived as related to one’s ability to control their HF and its symptoms has not been examined. Objective The purpose was to explore the experiences of people with HF in managing their illness (i.e., illness control), understand their perceptions of illness control after recent hospital readmission, and clarify the concept of illness control in people with chronic HF. Methods A qualitative approach, applied thematic analysis was employed. Purposive sampling was used to identify participants. Semi-structured interviews were conducted in 10 participants’ homes. Ongoing, concurrent, and comparative data analysis was used with ATLASti© data management software. Results Two themes were identified, strategies to control HF and barriers to controlling HF. Strategies to control HF included four subthemes: managing dietary intake and medications; self- advocacy; monitoring symptoms; and support. Barriers to control also had four subthemes: healthcare systems issues; health care professional relationships and interactions; personal characteristics; and knowledge deficits. Conclusion People use many different strategies to control HF. Control comes from both within and outside of the individual. The desire to control HF and its symptoms was evident, but implementing strategies is challenging and takes time, experience, and trial and error. Individuals did not view readmission negatively but as necessary to help them control their symptoms.

Summary: Quantifying the risk of progression to Alzheimer’s disease (AD) could help identify persons who could benefit from early interventions. We used data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI, n = 544, discovery cohort) and the National Alzheimer’s Coordinating Center (NACC, n = 508, validation cohort), subdividing individuals with mild cognitive impairment (MCI) into risk groups based on cerebrospinal fluid amyloid-β levels and identifying differential gray matter patterns. We then created models that fused neural networks with survival analysis, trained using non-parcellated T1-weighted brain MRIs from ADNI data, to predict the trajectories of MCI to AD conversion within the NACC cohort (integrated Brier score: 0.192 [discovery], and 0.108 [validation]). Using modern interpretability techniques, we verified that regions important for model prediction are classically associated with AD. We confirmed AD diagnosis labels using postmortem data. We conclude that our framework provides a strategy for risk-based stratification of individuals with MCI and for identifying regions key for disease prognosis.

A person's beliefs about their chronic condition (illness representations) influence health and treatment outcomes. Recently, researchers have used clustering approaches to identify subgroups with different patterns of beliefs about their illness, with some subgroups having more favorable health outcomes than others. To date, these findings have not been synthesized. The purpose of this systematic review of the literature was to synthesize results of studies that used clustering approaches to analyze illness representation in chronic disease populations, in order to characterize the clusters and their relationship to health outcomes. Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines we searched CINAHL, PsycInfo, and PubMed. To be included, studies had to be (a) peer reviewed, (b) in English, (c) performing a cluster analysis (CA), latent class analysis (LCA), or latent profile analysis (LPA), (d) using only illness representation (IR) subscales to form clusters, (e) measuring illness representation with the Illness Perception Questionnaire (IPQ-R), (f) in a chronic condition sample, and (g) measuring health-related outcomes. Twelve studies were included. Across studies, the number of clusters found ranged from two to three. In all studies, an association was found between illness representation group and at least one of their health outcomes. Illness representation clusters associated with favorable outcomes usually included lower disease-related consequences, fewer symptoms, less negative emotion, and a more stable disease pattern. The results of this review indicate that the relationship between the patterns of the illness representation profiles and health outcomes transcend diseases. Additionally, some dimensions of illness representation may be more important drivers of group membership than others.

BackgroundEarly life stress (ELS) has been linked to health disparities across the human lifespan, particularly increased risk for depression and its recurrence. In this study we explore two plausible and competing pathways through which ELS may lead to depression via inflammation.MethodsParticipants (ages 18-22; n = 41) completed the Early Trauma Inventory as a measure of ELS. Participants then completed consecutive daily diaries of mood and other sickness behavior for the 7 days prior to and 7 days after receiving the annual influenza vaccine. Circulating concentrations of plasma interleukin-6 (IL-6) were measured immediately before and 24 hr after vaccination.ResultsELS was not associated with the magnitude of change in IL-6 from pre- to post-vaccine, however, exposure to ELS moderated the association between change in IL-6 from pre- to post-vaccine and changes in both cognitive difficulty and depressed mood. Individuals exposed to greater ELS showed greater psychological sensitivity to increases in IL-6.ConclusionsExposure to ELS may increase sensitivity to peripheral inflammation in the central nervous system. Future studies elaborating on the impact of ELS on the sensitivity of specific neural circuits and cells to inflammation are needed.

ObjectiveSocial relationships can both influence and be influenced by immune processes. Past work implicates two distinct pathways along which this interaction may occur: inflammatory processes and antiviral processes. This article reviews how social behavior is modulated by these two immune processes and how such processes may in turn regulate social behavior.MethodsThis narrative review outlines existing work on social behavior and both inflammatory and antiviral processes. We propose an evolutionary framework that aims to integrate these findings. Specifically, social isolation has evolutionarily increased the likelihood of wounding and therefore increased the need for inflammation, which works to promote healing. Conversely, broader social networks provide protection from physical threats but also lead to increased pathogen exposure, necessitating a more robust antiviral response.ResultsThis review highlights that social adversity, such as social exclusion or loneliness, is associated with increased inflammation, whereas social contact is associated with increased antiviral immunity. Furthermore, increased inflammation leads to sensitivity to social stimuli, presumably to avoid hostile conspecifics and approach allies who may provide care while vulnerable. Individuals with inadequate antiviral immunity engage in behaviors that minimize pathogen exposure, such as reduced affiliative behavior.ConclusionsThis review suggests that adverse social experiences (social isolation, perceived social threat) may induce inflammatory responses while suppressing antiviral immunity, whereas positive experiences of social connection may reduce inflammation and bolster antiviral responses. Although acutely elevated inflammation would be adaptive under conditions where wounding is likely, chronic inflammation related to continued social adversity may have detrimental health consequences.

Individual attitudes and behavior related to health and disease are major components of clinical encounters. These factors shape lifestyle, presentation of symptoms, access to patient care, interactions between patients and physicians, adherence to medical advice, response to treatment. Health attitudes and behavior may range from anxiety and worry about illness, to various forms of denial, such as delay of seeking care and lack of adherence to treatment. When attitudes result in health-damaging behavior they may be particularly difficult to understand and become a source of frustration to both physicians and patients. Devising appropriate responses by health care providers may contribute to improving final outcomes and decrease health care costs. In particular, health behavior is likely to play a major role in the process of convalescence, in self-management of chronic conditions, in determining a state of recovery, and whenever a rehabilitation process is involved. Understanding the spectrum of health attitudes and behavior is also crucial for motivating people to make beneficial changes (lifestyle medicine), as well as for implementing safety procedures in the community.

BACKGROUND:Human mobility plays a central role in shaping pathogen transmission by generating spatial and/or individual variability in potential pathogen-transmitting contacts. Recent research has shown that symptomatic infection can influence human mobility and pathogen transmission dynamics. Better understanding the complex relationship between symptom severity, infectiousness, and human mobility requires quantification of movement patterns throughout infectiousness. For dengue virus (DENV), human infectiousness peaks 0-2 days after symptom onset, making it paramount to understand human movement patterns from the beginning of illness. METHODOLOGY AND PRINCIPAL FINDINGS:Through community-based febrile surveillance and RT-PCR assays, we identified a cohort of DENV+ residents of the city of Iquitos, Peru (n = 63). Using retrospective interviews, we measured the movements of these individuals when healthy and during each day of symptomatic illness. The most dramatic changes in mobility occurred during the first three days after symptom onset; individuals visited significantly fewer locations (Wilcoxon test, p = 0.017) and spent significantly more time at home (Wilcoxon test, p = 0.005), compared to when healthy. By 7-9 days after symptom onset, mobility measures had returned to healthy levels. Throughout an individual's symptomatic period, the day of illness and their subjective sense of well-being were the most significant predictors for the number of locations and houses they visited. CONCLUSIONS/SIGNIFICANCE:Our study is one of the first to collect and analyze human mobility data at a daily scale during symptomatic infection. Accounting for the observed changes in human mobility throughout illness will improve understanding of the impact of disease on DENV transmission dynamics and the interpretation of public health-based surveillance data.

Abstract Objective Young children experience physical complaints, like abdominal pain or minor injuries from playing, almost every day. These experiences may shape how they deal with health issues later in life. While models exist to explain illness perception in adults, information is lacking on the perspective of young children. This qualitative study aimed to explore important themes in the experience of everyday physical complaints in four- and five-year-old children, using children as informants. Study design 30 semi-structured interviews were performed in which four- and five-year-old children were questioned about their experiences with everyday physical complaints. The interviews were double coded using Atlas.ti and subsequently qualitative content analysis was used to define themes. Results All participating children were able to elaborate on their experiences with physical complaints. Three themes emerged from the interviews: causes of complaints, appraisal of complaints, and implications of complaints. In their appraisal of complaints, four- and five-year-old children made a distinction between visible and invisible complaints and real or pretended complaints. Conclusion Four- and five-year-old children can already give details about their experiences with everyday physical complaints. They have developed ideas about the causes and implications of complaints and try to make an appraisal.

Abstract Background Chronic low back pain (CLBP) is the leading cause of disability globally and is a major concern in public health. However, there is limited evidence on the prevalence and correlates of disability among adults in Sub-Saharan Africa. Thus, this study aimed at determining factors influencing disability among adult patients with CLBP in KwaZulu-Natal. Methods This analytical cross-sectional hospital-based study was conducted among adult CLBP patients in KwaZulu-Natal, South Africa. Data on disability, fear avoidance beliefs and illness behavior were gathered from 554 adult participants using self-administered questionnaires. Multiple linear regression analysis was conducted to determine factors associated with disability. Statistical significance was set at p

Background: Somatic symptom disorder (SSD) is common in medical settings but has been underdiagnosed. Stigma related to psychiatric illness was one of the barriers to making the diagnosis. More and more SSD patients who visited psychiatric clinics with physical complaints identify themselves as having 'autonomic dysregulation' in Taiwan. Aims: This study aimed to investigate the characteristics of patients with a subjective diagnosis of 'autonomic dysregulation'. Method: We assessed the sociodemographic profile, medical/psychiatric diagnoses, subjective psychiatric diagnoses, perceived psychiatric stigma, help-seeking attitude, and healthcare utilization of 122 participants with SSD. Participants who identified themselves as having 'autonomic dysregulation' (n = 84) were compared to those who did not (n=38). Results: Participants with a subjective diagnosis of 'autonomic dysregulation' were younger and had a higher education level than those who did not have such a subjective diagnosis. They also had higher scores on the Patient Health Questionnaire-15 (PHQ-15) and Health Anxiety Questionnaire (HAQ), whereas comorbid psychiatric diagnoses were similar in the two groups. Participants with and without a subjective diagnosis of 'autonomic dysregulation' did not have a significant difference in perceived psychiatric stigma and help-seeking attitude/behaviors. In a multiple logistic regression model, only age was associated with having a subjective diagnosis of 'autonomic dysregulation'. Conclusion: Among SSD patients, those who identify themselves as having 'autonomic dysregulation' tend to have higher somatic distress and health anxiety than those who do not. 'Autonomic dysregulation' is not associated with perceived psychiatric stigma. [ABSTRACT FROM AUTHOR]

Anecdotal reports and a small number of research studies suggest possible behavioral improvements in children with autism spectrum disorders (ASD) during a fever. However, previous studies rely largely on retrospective reports of this phenomenon. Establishing a robust association between fever and reduction of ASD‐related symptoms would promote opportunities for the development of innovative therapeutic interventions for children with ASD. In the current study, prospective data were collected from 141 children with ASD and 103 typically developing (TD) controls using parent responses to an 11‐item behavioral survey. Behaviors when no illness was present, during a fever, the week after a fever, and during non‐febrile illnesses for TD and ASD children were compared. Profiles of cases in which caregivers reported consistent behavioral improvements during fever are described. Data indicated worsening social, emotional/behavioral, and somatic symptoms during a fever regardless of diagnosis, with children with ASD demonstrating greater worsening of behaviors during a fever than TD children. Only three out of 141 children with ASD demonstrated consistent behavioral improvements during a fever; these children had a range of cognitive and adaptive skills. Children with ASD had stronger negative responses to fever than TD children. These findings contradict previous literature suggesting behavioral improvements for children with ASD. While improvements may occur for some children, it does not appear to be a common phenomenon. Additional research is needed to elucidate the nature of behavioral improvements in the subset of children with ASD who may respond positively to fever. Lay Summary: This study examines behavioral changes during fever and other medical events in children with autism compared to behavioral changes in a typically developing control group. Previous research and consistent subjective reports from parents and pediatricians suggest the possibility of behavioral improvements for children with autism during a fever. There is a lack of methodically collected data examining these effects. In the current study, children with autism consistently had stronger and more frequent negative behavior changes during fever than typically developing children (who also primarily showed worsening of behavior during fevers). Three out of 141 autistic children, and no typical children, showed improvements in varied areas during fevers. [ABSTRACT FROM AUTHOR]

Although at first glance inflammation and social behavior may appear unrelated, research points to an important role for inflammation in shaping social processes. This review summarizes findings in this field, specifically highlighting work that provides support for the idea that inflammation can lead to (1) increases in sensitivity to negative, threatening social experiences and (2) increases in sensitivity to positive, socially rewarding experiences. These diverging sensitivities in response to inflammation may depend on context and be adaptive for recuperation and recovery from illness. This review also discusses the implications of these findings for health and future research, including implications for depression, loneliness, and inflammatory disorders.

BackgroundInflammation plays a role in mood and behavior that may be relevant to identifying risk factors and treatment for depression and other stress-related illnesses. The purpose of this study was to examine whether fluctuations in inflammation following a mild immune stimulus were associated with changes in daily reported features of depression for up to a week in a healthy sample of young adults.MethodsForty-one undergraduate students completed daily diaries of mood, feelings of social disconnection, sleep, and physical symptoms for one week before and after receiving the seasonal influenza vaccine. Circulating plasma interleukin-6 (IL-6) was measured via blood samples taken immediately before and one day after vaccination.ResultsThere was a significant increase in circulating IL-6 from pre- to post-intervention (p = .008), and there was significant variability in the magnitude of IL-6 change. Greater increases in IL-6 were associated with greater mood disturbance on post-vaccine days, specifically depressed mood and cognitive symptoms.ConclusionsMinor increases in inflammation were associated with corresponding increases in features of depression, and these associations occurred in the absence of any physical symptoms. The influenza vaccine could be used to probe causal relationships with a high degree of ecological validity, even in high-risk and vulnerable populations, to better understand the role of inflammation in the pathogenesis of depression.

In ectothermic vertebrates, behavioral fever, where an individual actively seeks warmer areas, seems to be a primary response to pathogens. This is considered a broad and evolutionarily conserved response among vertebrates. Recent population declines in amphibians are associated with an increase of infectious disease driven largely by climate change, habitat degradation, and pollution. Immediate action through research is required to better understand and inform conservation efforts. The literature available, does not provide unifying concepts that can guide adequate experimental protocols and interpretation of data, especially when studying animals in the field. The aim of this review is to promote common understanding of terminology and facilitating improved comprehension and application of key concepts about the occurrence of both sickness behavior or behavioral fever in ectothermic vertebrates. We start with a conceptual synthesis of sickness behavior and behavioral fever, with examples in different taxa. Through this discussion we present possible paths to standardize terminology, starting from original use in endothermic tetrapods which was expanded to ectothermic vertebrates, particularly amphibians and reptiles. This conceptual expansion from humans (endothermic vertebrates) and then to ectothermic counterparts, gravitates around the concept of 'normality'. Thus, following this discussion, we highlight caveats with experimental protocols and state the need of a reference value considered normal (RVCN), which is different from experimental control and make recommendations regarding experimental procedures and stress the value of detailed documentation of behavioral responses. We also propose some future directions that could enhance interaction among disciplines, emphasizing relationships at different levels of biological organization. This is crucial given the increasing convergence of fields such as thermal physiology, immunology, and animal behavior due to emerging diseases and other global crises impacting biodiversity., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Social withdrawal is a well-established part of sickness behavior, but in some contexts sick animals might gain from keeping close instead of keeping away. For instance, sick individuals are more willing to be near known individuals who can provide care and safety (close others) compared to when healthy. Yet, interactions with some strangers might also be beneficial (i.e., healthcare professionals), but it is not known how sickness interplay with social behavior towards such individuals. Here, we assessed if sickness affects perception of caregivers, and developed a new task, the Caregiver Perception Task (CgPT). Twenty-six participants performed the CgPT, once after an injection of lipopolysaccharide (LPS, 0.8 ng/kg body weight, n = 24), and once after an injection of saline (n = 25), one hour and forty-five minutes post-injection. During the task, participants watched short video clips of three types of caregivers: a healthcare professional taking care of a sick individual, a healthcare professional not taking care of a sick individual, and a non-healthcare professional taking care of their sick adult child or partner. After each video clip, the likability, trustworthiness, professionalism, and willingness to interact with and receive care from the caregiver were rated on visual analogue scales. Results showed that participants injected with saline rated healthcare professionals who did not take care of a sick individual less positively on all aspects compared to healthcare professionals who took care of a sick individual. Moreover, compared to saline, LPS increased the participants' willingness to receive care from healthcare professionals and non-healthcare professionals providing care, but not from healthcare professionals not providing care. Thus, our results indicate that sick individuals may approach unknown individuals with potential to provide care and support., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Objective: Young children experience physical complaints, like abdominal pain or minor injuries from playing, almost every day. These experiences may shape how they deal with health issues later in life. While models exist to explain illness perception in adults, information is lacking on the perspective of young children. This qualitative study aimed to explore important themes in the experience of everyday physical complaints in four- and five-year-old children, using children as informants.Study Design: 30 semi-structured interviews were performed in which four- and five-year-old children were questioned about their experiences with everyday physical complaints. The interviews were double coded using Atlas.ti and subsequently qualitative content analysis was used to define themes.Results: All participating children were able to elaborate on their experiences with physical complaints. Three themes emerged from the interviews: causes of complaints, appraisal of complaints, and implications of complaints. In their appraisal of complaints, four- and five-year-old children made a distinction between visible and invisible complaints and real or pretended complaints.Conclusion: Four- and five-year-old children can already give details about their experiences with everyday physical complaints. They have developed ideas about the causes and implications of complaints and try to make an appraisal. [ABSTRACT FROM AUTHOR]

Background: Chronic low back pain (CLBP) is the leading cause of disability globally and is a major concern in public health. However, there is limited evidence on the prevalence and correlates of disability among adults in Sub-Saharan Africa. Thus, this study aimed at determining factors influencing disability among adult patients with CLBP in KwaZulu-Natal.Methods: This analytical cross-sectional hospital-based study was conducted among adult CLBP patients in KwaZulu-Natal, South Africa. Data on disability, fear avoidance beliefs and illness behavior were gathered from 554 adult participants using self-administered questionnaires. Multiple linear regression analysis was conducted to determine factors associated with disability. Statistical significance was set at p < 0.05.Results: Based on the multivariable linear regression, being a female (β = 0.343, p < 0.001) and fear avoidance beliefs about work (β = 0.221, p = 0.044) were significantly associated with greater disability, while, smoking 1 to 10 cigarettes per day (β = -0.106, p = 0.011) and higher illness behaviour scores (β = -0.165, p = 0.024) were significantly associated with less disability The model accounted for 20% of the total variance in Oswestry disability scores.Conclusion: This study has concluded that disability in CLBP is predicted by multiple of factors, with psychosocial factors (fear avoidance beliefs and heavy cigarette smoking) playing a significant role. Manual work was also identified as a significant predictor of CLBP disability. Therefore, guidelines should emphasize on early identification of these yellow flags in primary care.

Sickness behavior reflects a state of altered physiology and central nervous system function that occurs during systemic infection or inflammation, serving as an adaptive response to illness. This study aims to elucidate the role of hydrogen sulfide (H 2 S) in regulating sickness behavior and neuroinflammatory responses in a rat model of systemic inflammation. Adult male Wistar rats were treated with lipopolysaccharide (LPS) to induce sickness behavior. Intracerebroventricular (i.c.v.) pretreatments included aminooxyacetic acid (AOAA), an inhibitor of H 2 S synthesis, and sodium sulfide (NaHS), an H 2 S donor. Behavioral assays were conducted, along with the assessment of astrocyte activation, as indicated by GFAP expression in the hypothalamus. Pretreatment with NaHS mitigated LPS-induced behavioral changes, including hypophagia, social and exploratory deficits, without affecting peripheral cytokine levels, indicating a central modulatory effect. AOAA, conversely, accentuated certain behavioral responses, suggesting a complex role of endogenous H 2 S in sickness behavior. These findings were reinforced by a lack of effect on plasma interleukin levels but significant reduction in GFAP expression. Our findings support the central role of H 2 S in modulating neuroinflammation and sickness behavior, highlighting the therapeutic potential of targeting H 2 S signaling in neuroinflammatory conditions. • Hydrogen sulfide eases behavioral impact of lipopolysaccharide in rats. • NaHS counters LPS-induced behavioral changes effectively in rodent models. • AOAA enhances LPS-induced hypophagia, pointing to complex H2S roles. • H2S demonstrates significant neuroprotective actions against LPS in CNS. • NaHS icv use shows no change in cytokine levels LPS-induced, indicating central action.

Background: Huntington's disease (HD) commonly presents with impaired social functioning. Specifically, many patients exhibit social withdrawal, or decreased engagement in social activities. Despite the frequency of social withdrawal in HD, no review has been previously published on this subject. Objective: The aim of this study was to conduct a scoping review of social withdrawal in HD. Methods: Two searches were conducted to identify relevant literature. The articles were screened by title and abstract, followed by full text review for all remaining articles. Consistent with scoping review methodology, data extraction focused on identification of broad themes and knowledge gaps. Results: Eight articles were identified that described social withdrawal in HD. Social withdrawal was exhibited by individuals with varying disease severity, and it occurred both within and outside of the home. Social withdrawal was associated with increased caregiver burden, behavioral issues, and psychiatric, cognitive, and physiological changes. Only one case study described an intervention that increased social participation in a previously withdrawn patient. Conclusion: Although social withdrawal is commonly encountered in clinical settings, this review highlights the need for prospective studies to systematically evaluate social withdrawal in HD. These studies should be designed to consider disease stage and associated HD features as well as caregiver burden and potential interventions. Additionally, objective measures of social withdrawal should be used when possible, as existing instruments measure perceptions of participation levels rather than actual withdrawal behavior. Such studies will lay the groundwork to improve social functioning and quality of life for people with HD. [ABSTRACT FROM AUTHOR]

Background: Approximately 57 million physician appointments annually in the United Kingdom are for minor ailments. These illnesses could be self-cared for, which would potentially lower patients' anxiety, increase their confidence, and be more convenient. In a randomized controlled trial of the Internet Dr digital intervention, patients with access to the intervention had fewer consultations for respiratory tract infections (RTIs). Having established intervention efficacy, further examination of trial data is required to understand how the intervention works. Objective: This paper reports a process evaluation of Internet Dr usage by the intervention group. The evaluation aims to demonstrate how meaningful usage metrics (ie, interactions that are specific and relevant to the intervention) can be derived from the theoretical principles underlying the intervention, then applied to examine whether these interactions are effective in supporting self-care for RTIs, for whom, and at what time. Methods: The Internet Dr trial recorded patients' characteristics and usage data over 24 weeks. At follow-up, users reported whether their levels of enablement to cope with their illness changed over the trial period. The Medical Research Council process evaluation guidance and checklists from the framework for Analyzing and Measuring Usage and Engagement Data were applied to structure research questions examining associations between usage and enablement. Results: Viewing pages containing advice on caring for RTIs were identified as a meaningful metric for measuring intervention usage. Almost half of the users (616/1491, 42.31%) viewed at least one advice page, with most people (478/616, 77.6%) accessing them when they initially enrolled in the study. Users who viewed an advice page reported increased enablement to cope with their illness as a result of having participated in the study compared with users who did not (mean 2.12, SD 2.92 vs mean 1.65, SD 3.10; mean difference 0.469, 95% CI 0.082-0.856). The target population was users who had visited their general practitioners for an RTI in the year before the trial, and analyses revealed that this group was more likely to access advice pages (odds ratio 1.35, 95% CI 1.159-1.571; P<.001). Conclusions: The process evaluation identifies viewing advice pages as associated with increased enablement to self-care, even when accessed in the absence of a RTI, meaning that dissemination activities need not be restricted to targeting users who are ill. The intervention was effective at reaching the target population of users who had previously consulted their general practitioners. However, attrition before reaching advice pages was high, highlighting the necessity of prioritizing access during the design phase. These findings provide guidance on how the intervention may be improved and disseminated and have wider implications for minor ailment interventions. [ABSTRACT FROM AUTHOR]

PurposeBreast cancer diagnosis and treatment are associated with increased inflammatory activity, which can induce sickness symptoms. We examined whether emotional acceptance moderates the association between proinflammatory cytokines and self-reported sickness symptoms in women recently diagnosed with breast cancer.MethodsWomen (N=136) diagnosed with stage 0-III breast cancer within the previous 6months provided plasma samples and completed the FACT: Physical Well-Being Scale, as well as the Acceptance of Emotion Scale every 3months for 2years. At each time point, we quantified interleukin (IL)-6, IL-8, IL-10, and tumor necrosis factor (TNF)-α using a high sensitivity multiplex assay.ResultsHigher within-subject mean TNF-α across all time-points predicted higher mean sickness symptoms. At individual time-points, higher IL-6 and IL-8 levels were associated with higher sickness symptoms. Mean emotional acceptance across all time-points moderated the relationship between mean IL-8 and sickness symptoms, with sickness symptoms remaining persistently high in women with low emotional acceptance even when IL-8 levels were low. At individual time-points, emotional acceptance positively moderated the correlations of IL-8 and TNF-α with sickness symptoms, such that the associations between higher levels of these proinflammatory cytokines and higher sickness symptoms were attenuated when emotional acceptance was high.ConclusionEmotional acceptance was shown for the first time to moderate the associations of cytokines with sickness symptoms in breast cancer patients over time following diagnosis and treatment. The association between emotional acceptance and sickness symptoms was significantly different from zero but relatively small in comparison to the range of sickness symptoms. Results suggest that targeting emotion regulation may help to break the cycle between inflammation and sickness symptoms in women with breast cancer.

Sadness is an emotion universally recognized across cultures, suggesting it plays an important functional role in regulating human behavior. Numerous adaptive explanations of persistent sadness interfering with daily functioning (hereafter "depression") have been proposed, but most do not explain frequent bidirectional associations between depression and greater immune activation. Here we test several predictions of the host defense hypothesis, which posits that depression is part of a broader coordinated evolved response to infection or tissue injury (i.e. "sickness behavior") that promotes energy conservation and reallocation to facilitate immune activation. In a high pathogen population of lean and relatively egalitarian Bolivian forager-horticulturalists, we test whether depression and its symptoms are associated with greater baseline concentration of immune biomarkers reliably associated with depression in Western populations (i.e. tumor necrosis factor alpha [TNF-α], interleukin-1 beta [IL-1β], interleukin-6 [IL-6], and C-reactive protein [CRP]). We also test whether greater pro-inflammatory cytokine responses to ex vivo antigen stimulation are associated with depression and its symptoms, which is expected if depression facilitates immune activation. These predictions are largely supported in a sample of older adult Tsimane (mean±SD age=53.2±11.0, range=34-85, n=649) after adjusting for potential confounders. Emotional, cognitive and somatic symptoms of depression are each associated with greater immune activation, both at baseline and in response to ex vivo stimulation. The association between depression and greater immune activation is therefore not unique to Western populations. While our findings are not predicted by other adaptive hypotheses of depression, they are not incompatible with those hypotheses and future research is necessary to isolate and test competing predictions.

Atrial fibrillation (AF) is the most common arrhythmia in the world. Despite the increasing prevalence, there remains a limited understanding of how the pre-diagnosis symptom experience varies by gender. The purpose of this study was to retrospectively explore gender differences/similarities in the pre-diagnosis period of AF. Twenty-six adults (13 men and 13 women) were interviewed guided by the Symptom Experience in AF (SEAF). Data were analyzed using a two-step approach to thematic analysis. Women had greater challenges receiving a timely diagnosis, with 10 women (77%) experiencing symptoms ≥1 year prior to their diagnosis, in comparison to only three (23%) of the men. Women also reported more severe symptoms, less AF-related knowledge, viewed themselves as low risk for cardiovascular disease, and described how their comorbid conditions confused AF symptom evaluation. This study provides a foundational understanding of differences/similarities in the AF symptom experience by gender. [ABSTRACT FROM AUTHOR]
