RESUMEN

Myalgic encephalomyelitis/chronic fatigue (ME/CFS) is a post-infectious, chronic disease that can lead to severe impairment and, even, total disability. Although the disease has been known for a long time, and has been coded in the ICD since 1969 (G93.3), medical research has not yet been able to reach a consensus regarding its physiological basis and how best to treat it. Against the background of these shortcomings, psychosomatic disease models have been developed and psychotherapeutic treatments have been derived from them, but their empirical testing has led to sobering results. According to the current state of research, psychotherapy and psychosomatic rehabilitation have no curative effect in the treatment of ME/CFS. Nevertheless, we see numerous patients in practices and outpatient clinics who suffer severely as a result of their illness and whose mental well-being and coping strategies would benefit from psychotherapeutic help. In this article, we outline a psychotherapeutic approach that serves this need, taking into account two basic characteristics of ME/CFS: firstly, the fact that ME/CFS is a physical illness and that curative treatment must therefore be physical; and secondly, the fact that post exertional malaise (PEM) is a cardinal symptom of ME/CFS and thus warrants tailored psychotherapeutic attention.

RESUMEN

Tobacco smoking has been associated with lower cardiovascular reactivity to psychological stress in middle-aged samples, but its impact on cardiovascular reactivity to stress in young adults remains unclear. The present study examined whether young healthy adults showed differing cardiovascular stress reaction profiles depending on their smoking status. Across two laboratory studies (N = 64 and N = 114), we asked participants to complete cognitive stress-tasks while undergoing continuous hemodynamic monitoring. In both studies, there was not a statistically signification association between systolic blood pressure, diastolic blood pressure, or heart rate reactivity to stress (all ps > .05). However, examination of the underlying hemodynamic profile of the stress response suggested differences between non-smokers and smokers in both studies. In Study 1, non-smokers exhibited the expected myocardial response to the active stress-task; however, smokers exhibited a mixed hemodynamic profile. In Study 2, smokers evidenced a weaker myocardial profile to the active stress-tasks compared to non-smokers. However, the examination of the continuous hemodynamic profile score (HP) did not identify statistical differences. These results highlight that any level of the smoking habit is associated with an altered hemodynamic profile in response to stress in smokers, which may have important implications for long-term cardiovascular health. The findings also suggest that controlling for smoking behavior in reactivity research examining blood pressure and heart rate responses to stress in young adults is not necessary.

RESUMEN

BACKGROUND: The COVID-19 pandemic has posed significant challenges for healthcare systems to meet patients' and families' complex care needs, including spiritual care needs. Little data are available about spiritual care delivery in light of the pandemic. AIM: This study examined the impact of COVID-19 on spiritual care by healthcare chaplains in the United States. DESIGN: An online survey of 563 board-certified chaplains was conducted from March to July 2020. The survey, designed to identify chaplains' roles in facilitating conversations about goals of care, included an open-ended question asking how COVID-19 affected chaplaincy practices; 236 chaplains responded. Quantitative data and written qualitative responses were analyzed using descriptive analysis and content analysis, respectively. SETTING/PARTICIPANTS: Majority of participants were white (88%), female (59%), Protestant (53%), and employed full time (86%). Almost half were working in community hospitals (45%) and designated to one or more special units (48%) including ICU, palliative care, and oncology. RESULTS: Three major themes emerged from chaplains' qualitative responses: (1) COVID-19-related risk mitigation and operational changes; (2) impact of social distancing guidelines; and (3) increased need for and provision of psychosocial and spiritual support. CONCLUSIONS: Chaplains reported that COVID-19 challenges contributed to greater social isolation, and mental health concerns for patients, families, and healthcare staff, and substantially changed the way healthcare chaplains provided spiritual care. With evolving healthcare contexts, developing safer, more creative modes of spiritual care delivery while offering systematic support for chaplains can help meet the increasing psychosocial and spiritual needs of patients, families, and healthcare team members.

RESUMEN

In a paper published in the Journal of the Royal Society of Medicine, Adamson et al. (2020) interpret data as showing that cognitive behavioural therapy leads to improvement in patients with chronic fatigue syndrome and chronic fatigue. Their research is undermined by several methodological limitations, including: (a) sampling ambiguity; (b) weak measurement; (c) survivor bias; (d) missing data and (e) lack of a control group. Unacknowledged sample attrition renders statements in the published Abstract misleading with regard to points of fact. That the paper was approved by peer reviewers and editors illustrates how non-rigorous editorial processes contribute to systematic publication bias.

RESUMEN

BACKGROUND: Fatigue and psychophysiological reactions to mental stress are known to be problematic in coronary artery disease (CAD) patients. Currently, studies exploring the relationship between fatigue and cardiovascular reactivity to stress are scarce and inconsistent. The current study aimed to investigate the links between cardiovascular response to mental stress and fatigue in CAD patients after acute coronary syndrome (ACS). METHODS: The cross-sectional study investigated 142 CAD patients (85% males, 52 ± 8 years) within 2-3 weeks after recent myocardial infarction or unstable angina pectoris. Fatigue symptoms were measured using Multidimensional Fatigue Inventory 20-items, while cardiovascular reactivity to stress [i.e., systolic (S) and diastolic (D) blood pressure (ΔBP), and heart rate (ΔHR)] was evaluated during Trier Social Stress Test (TSST). In addition, participants completed psychometric measures, including the Hospital Anxiety and Depression scale and the Type D Scale-14. Multivariable linear regression analyses were completed to evaluate associations between fatigue and cardiovascular response to TSST, while controlling for confounders. RESULTS: After controlling for baseline levels of cardiovascular measures, age, gender, education, heart failure severity, arterial hypertension, smoking history, use of nitrates, anxiety and depressive symptoms, Type D Personality, perceived task difficulty, and perceived task efforts, cardiovascular reactivity to anticipatory stress was inversely associated with both global fatigue (ΔHR: ß = -0.238; p = 0.04) and mental fatigue (ΔSBP: ß = -0.244; p = 0.04; ΔHR ß = -0.303; p = 0.01) as well as total fatigue (ΔSBP: ß = -0.331; p = 0.01; ΔHR: ß = -0.324; p = 0.01). CONCLUSION: In CAD patients after ACS, fatigue was linked with diminished cardiovascular function during anticipation of a mental stress challenge, even after inclusion of possible confounders. Further similar studies exploring other psychophysiological stress responses are warranted.

RESUMEN

BACKGROUND: Decreases in bone density of the scapula due to age and disease can make orthopedic procedures such as arthroplasty and fracture fixation challenging. There is limited information in the literature regarding the effect of age and sex on the patterns of these density changes across the bone. Characterizing these changes could assist the surgeon in planning optimal instrumentation placement. METHODS: Ninety-seven 3-dimensional models of the scapula were segmented from routine clinical computed tomography scans, and an opportunistic quantitative computed tomography approach was used to obtain detailed calibrated bone density measurements for each bone model. The effects of age and sex on cortical and trabecular bone density were assessed for the entire scapula. Specific regions (eg, scapular spine) where these factors had a significant effect were identified. Three-dimensional models were generated to allow clear visualization of the changes in density patterns. RESULTS: Cortical bone loss averaged 1.0 mg/cm3 and 0.3 mg/cm3 per year for female and male subjects, respectively, and trabecular bone loss averaged 1.6 mg/cm3 and 1.2 mg/cm3, respectively. However, several regions had loss rates several times greater. Areas that were significantly affected by age included the acromion, scapular spine, base of the coracoid, inferior glenoid neck, and glenoid vault. Areas that were significantly affected by sex were the scapular spine and body. CONCLUSIONS: These findings provide evidence that the bone density distribution across the scapula changes non-uniformly because of factors including sex and age. Despite overall trends of bone loss, there remains significant variability between individuals, and subject-specific tools for planning surgical procedures in which scapular fixation is required may be beneficial.

RESUMEN

BACKGROUND: Healthcare chaplains have key roles in providing palliative support to patients and families, and they are well-suited to facilitate advance care planning (ACP). However, empirical data on the roles and responsibilities of chaplains in facilitating ACP are limited. OBJECTIVES: To examine the roles of board-certified healthcare chaplains in ACP in various healthcare settings. METHODS: A cross-sectional, web-based self-report survey was conducted with 585 board-certified chaplains recruited from 3 major professional chaplains' organizations in the U.S. The survey data included chaplains' demographic and professional characteristics, their roles and responsibilities, and responses regarding communication and participation with other healthcare team members in facilitating ACP, including experienced barriers. RESULTS: More participants worked in community hospital settings (42%) and academic medical centers (19.6%) than in any other setting. Over 90% viewed ACP as an important part of their work, 70% helped patients complete advance directives, and 90% helped patients discuss their preferences about end-of-life treatments. Many chaplains were not consistently included in team discussions regarding decision-making, although most chaplains reported that they could always find ways to communicate with their teams. CONCLUSION: Professional board-certified chaplains regularly engage in facilitating ACP discussions with patients and families in various healthcare settings. There is a need to recognize and provide systematic support for the role of chaplains in facilitating ACP conversations and to integrate chaplains into routine interdisciplinary team and family meetings.

RESUMEN

Cellular senescence contributes to age-related disorders including physical dysfunction, disabilities, and mortality caused by tissue inflammation and damage. Senescent cells accumulate in multiple tissues with aging and at etiological sites of multiple chronic disorders. The senolytic drug combination, Dasatinib plus Quercetin (D+Q), is known to reduce senescent cell abundance in aged mice. However, the effects of long-term D+Q treatment on intestinal senescent cell and inflammatory burden and microbiome composition in aged mice remain unknown. Here, we examine the effect of D+Q on senescence (p16Ink4a and p21Cip1) and inflammation (Cxcl1, Il1ß, Il6, Mcp1, and Tnfα) markers in small (ileum) and large (caecum and colon) intestine in aged mice (n = 10) compared to age-matched placebo-treated mice (n = 10). Additionally, we examine microbial composition along the intestinal tract in these mice. D+Q-treated mice show significantly lower senescent cell (p16 and p21 expression) and inflammatory (Cxcl1, Il1ß, Il6, Mcp1, and Tnfα expression) burden in small and large intestine compared with control mice. Further, we find specific microbial signatures in ileal, cecal, colonic, and fecal regions that are distinctly modulated by D+Q, with modulation being most prominent in small intestine. Further analyses reveal specific correlation of senescence and inflammation markers with specific microbial signatures. Together, these data demonstrate that the senolytic treatment reduces intestinal senescence and inflammation while altering specific microbiota signatures and suggest that the optimized senolytic regimens might improve health via reducing intestinal senescence, inflammation, and microbial dysbiosis in older subjects.

RESUMEN

The use of graded exercise therapy and cognitive behavioural therapy for myalgic encephalomyelitis/chronic fatigue syndrome has attracted considerable controversy. This controversy relates not only to the disputed evidence for treatment efficacy but also to widespread reports from patients that graded exercise therapy, in particular, has caused them harm. We surveyed the National Health Service-affiliated myalgic encephalomyelitis/chronic fatigue syndrome specialist clinics in England to assess how harms following treatment are detected and to examine how patients are warned about the potential for harms. We sent 57 clinics standardised information requests under the United Kingdom's Freedom of Information Act. Data were received from 38 clinics. Clinics were highly inconsistent in their approaches to the issue of treatment-related harm. They placed little or no focus on the potential for treatment-related harm in their written information for patients and for staff. Furthermore, no clinic reported any cases of treatment-related harm, despite acknowledging that many patients dropped out of treatment. In light of these findings, we recommend that clinics develop standardised protocols for anticipating, recording, and remedying harms, and that these protocols allow for therapies to be discontinued immediately whenever harm is identified.

RESUMEN

BACKGROUND: Patients with major depressive disorder (MDD) who attempt or complete suicide have elevated inflammation compared to nonsuicidal patients with MDD. However, greater severity of depression and the medical lethality of suicide attempts could account for such elevated inflammation in suicide attempters and suicide completers. METHODS: To clarify, we measured inflammatory markers in patients with MDD with and without high levels of suicidal ideation and in nondepressed controls (N = 124). Levels of suicidal ideation, depression severity, and recent suicide attempts were assessed by structured clinical interviews. A composite score including the inflammatory markers tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), and C-reactive protein (CRP) was used as an inflammatory index. Analysis of covariance models were used to assess group differences with adjustments for age and gender. RESULTS: Patients with MDD and high suicidal ideation had significantly higher inflammatory index scores than both controls, F(1,53) = 18.08, partial η(2) = .25, P < .001, and patients with MDD and lower suicidal ideation F(1,44) = 7.59, partial η(2) = .15, P = .009. In contrast, patients with lower suicidal ideation were not significantly different from controls on the inflammatory index, F(1,63) = .52, partial η(2) = .01, P = .47. Follow-up analyses indicated that differences between patients with MDD and high versus lower suicidal ideation were independent of depression severity and recent suicide attempts. CONCLUSIONS: Suicidal ideation may be uniquely associated with inflammation in depressed patients.

RESUMEN

The presence of unsaturated lipids in lung surfactant is important for proper respiratory function. In this work, we have used neutron reflection and surface pressure measurements to study the reaction of the ubiquitous pollutant gas-phase ozone, O3, with pure and mixed phospholipid monolayers at the air-water interface. The results reveal that the reaction of the unsaturated lipid 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine, POPC, with ozone leads to the rapid loss of the terminal C9 portion of the oleoyl strand of POPC from the air-water interface. The loss of the C9 portion from the interface is accompanied by an increase in the surface pressure (decrease in surface tension) of the film at the air-water interface. The results suggest that the portion of the oxidized oleoyl strand that is still attached to the lipid headgroup rapidly reverses its orientation and penetrates the air-water interface alongside the original headgroup, thus increasing the surface pressure. The reaction of POPC with ozone also leads to a loss of material from the palmitoyl strand, but the loss of palmitoyl material occurs after the loss of the terminal C9 portion from the oleoyl strand of the molecule, suggesting that the palmitoyl material is lost in a secondary reaction step. Further experiments studying the reaction of mixed monolayers composed of unsaturated lipid POPC and saturated lipid dipalmitoyl-sn-glycero-3-phosphocholine, DPPC, revealed that no loss of DPPC from the air-water interface occurs, eliminating the possibility that a reactive species such as an OH radical is formed and is able to attack nearby lipid chains. The reaction of ozone with the mixed films does cause a significant change in the surface pressure of the air-water interface. Thus, the reaction of unsaturated lipids in lung surfactant changes and impairs the physical properties of the film at the air-water interface.

RESUMEN

This study assessed the combined effects of coping style and intra-procedural information on indices of distress (physiological measures, observed distress, self-report measures of anxiety and affect) among a group of patients undergoing colposcopy. High and low monitors were exposed to one of three interventions: high information (live video feed of colposcopy); low information (complete audiovisual distraction); and control. Results revealed a 2 (monitoring style) × 3 (information level) × 2 (time) interaction for systolic blood pressure (SBP), F(2, 111) = 3.55, p = .032. Among low monitors, patients in the low-information group exhibited significant SBP reductions during colposcopy, while those in the high-information group exhibited SBP increases. Among high monitors, patients in the high-information and control groups exhibited SBP reductions. Further, significant differences in observed signs of distress were found between groups with high monitors in the low-information group faring best overall, F(2, 111) = 4.41, p = .014. These findings indicate that tailoring information to suit individual coping style may maximize the apparent efficacy of interventions aimed at reducing stress during medical examinations.

RESUMEN

PURPOSE: The development of computer-aided diagnostic (CAD) methods for lung nodule detection, classification, and quantitative assessment can be facilitated through a well-characterized repository of computed tomography (CT) scans. The Lung Image Database Consortium (LIDC) and Image Database Resource Initiative (IDRI) completed such a database, establishing a publicly available reference for the medical imaging research community. Initiated by the National Cancer Institute (NCI), further advanced by the Foundation for the National Institutes of Health (FNIH), and accompanied by the Food and Drug Administration (FDA) through active participation, this public-private partnership demonstrates the success of a consortium founded on a consensus-based process. METHODS: Seven academic centers and eight medical imaging companies collaborated to identify, address, and resolve challenging organizational, technical, and clinical issues to provide a solid foundation for a robust database. The LIDC/IDRI Database contains 1018 cases, each of which includes images from a clinical thoracic CT scan and an associated XML file that records the results of a two-phase image annotation process performed by four experienced thoracic radiologists. In the initial blinded-read phase, each radiologist independently reviewed each CT scan and marked lesions belonging to one of three categories ("nodule > or =3 mm," "nodule <3 mm," and "non-nodule > or =3 mm"). In the subsequent unblinded-read phase, each radiologist independently reviewed their own marks along with the anonymized marks of the three other radiologists to render a final opinion. The goal of this process was to identify as completely as possible all lung nodules in each CT scan without requiring forced consensus. RESULTS: The Database contains 7371 lesions marked "nodule" by at least one radiologist. 2669 of these lesions were marked "nodule > or =3 mm" by at least one radiologist, of which 928 (34.7%) received such marks from all four radiologists. These 2669 lesions include nodule outlines and subjective nodule characteristic ratings. CONCLUSIONS: The LIDC/IDRI Database is expected to provide an essential medical imaging research resource to spur CAD development, validation, and dissemination in clinical practice.

RESUMEN

The reaction between gas-phase ozone and monolayers of the unsaturated lipid 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine, POPC, on aqueous solutions has been studied in real time using neutron reflection and surface pressure measurements. The reaction between ozone and lung surfactant, which contains POPC, leads to decreased pulmonary function, but little is known about the changes that occur to the interfacial material as a result of oxidation. The results reveal that the initial reaction of ozone with POPC leads to a rapid increase in surface pressure followed by a slow decrease to very low values. The neutron reflection measurements, performed on an isotopologue of POPC with a selectively deuterated palmitoyl strand, reveal that the reaction leads to loss of this strand from the air-water interface, suggesting either solubilization of the product lipid or degradation of the palmitoyl strand by a reactive species. Reactions of (1)H-POPC on D(2)O reveal that the headgroup region of the lipids in aqueous solution is not dramatically perturbed by the reaction of POPC monolayers with ozone supporting degradation of the palmitoyl strand rather than solubilization. The results are consistent with the reaction of ozone with the oleoyl strand of POPC at the air-water interface leading to the formation of OH radicals. The highly reactive OH radicals produced can then go on to react with the saturated palmitoyl strands leading to the formation of oxidized lipids with shorter alkyl tails.

RESUMEN

OBJECTIVE: To prospectively test the efficacy of a device for the home treatment of benign paroxysmal positional vertigo (BPPV). DESIGN: Multicenter prospective cohort study. SETTING: Community and tertiary care clinic offices and patient homes. PATIENTS: Forty patients with active BPPV. INTERVENTIONS: Training on and treatment with a home treatment device (The DizzyFIX) as their primary therapy technique. MAIN OUTCOME MEASURE: The Dix-Hallpike maneuver at 1 week after treatment. RESULTS: Patients using the home treatment device had no evidence of nystagmus in posttreatment Dix-Hallpike maneuvers at 1 week in 88% of cases (n = 40). This rate was comparable to standard treatment. There were no significant complications. CONCLUSION: The use of this device enables patients with an established diagnosis of posterior canal BPPV to safely conduct an effective particle repositioning maneuver and achieve success rates similar to those found with the standard Epley maneuver.

RESUMEN

OBJECTIVE: This study reviewed the experience and outcomes of 1 surgical team (L.S.P., S.P.L.) using the transcrusal approach. METHODS: Ten-year retrospective review of 17 consecutive patients requiring transcrusal exposure of the petrous apex and upper brainstem was performed. The main outcome measures included hearing and facial nerve preservation as measured by standard audiography and postoperative assessment using the House-Brackmann scale. RESULTS: Operative indications included meningioma (5 patients), epidermoid/dermoid cyst (3 patients), trigeminal schwannoma (3 patients), giant or large upper basilar artery aneurysm (3 patients), pontine cavernoma (1 patient), chondrosarcoma (1 patient), and clival melanocytoma (1 patient). Average tumor size was 3.6 cm. Complete resection was achieved in 50% of patients with petroclival tumors. Follow-up data were obtained for 14 patients at 20 +/- 4 months. Serviceable hearing was preserved in 58%. Sixty-four percent of patients demonstrated House-Brackmann stage I facial nerve function. Two patients died perioperatively (brainstem infarction). Two patients became hemiparetic, with 1 improving substantially. CSF leaks developed in 3 patients. Forty-seven percent of patients demonstrated cranial nerve V deficits. Forty-one percent of patients demonstrated deficits of cranial nerve III, IV, or VI. Vertigo, vestibular disturbance, hydrocephalus, temporal lobe contusion, or hematoma did not develop in any patients. CONCLUSION: The transcrusal approach provides adequate exposure for most petroclival lesions and giant aneurysms of the upper basilar artery while offering the possibility of hearing preservation. Like all approaches to large tumors and aneurysms in this region, there is a significant risk of morbidity and mortality. However, this approach is an excellent alternative to other techniques that necessitate deliberate sacrifice of ipsilateral hearing.

RESUMEN

Anxiety confers increased risk for inflammatory diseases, and elevated inflammatory activity in anxious individuals may contribute to this increased risk. One complication, however, is that anxiety could be associated with inflammatory activity either through a specific anxiety pathway or through a more general negative emotionality pathway. To investigate, we measured levels of the stress hormone cortisol, the pro-inflammatory cytokine interleukin-6 (IL-6), and the systemic inflammatory marker C-reactive protein (CRP), as well as depression and neuroticism, in clinically anxious and non-anxious adults. Compared with non-anxious participants, clinically anxious participants exhibited significantly lower levels of morning cortisol and significantly higher levels of IL-6, independent of age, sex, and depressive symptoms. These group differences were robust when controlling for neuroticism. Conversely, the groups had equivalent levels of CRP in all analyses. Results are indicative of anxiety-specific effects on inflammatory activity, and highlight a pathway by which anxiety may increase risk for inflammatory diseases.

RESUMEN

Previous research has been equivocal as to the impact of smoking status on cardiovascular reactivity to challenge. In addition, little is known about patterns of cardiovascular response habituation-sensitization to repeated challenge, in either smokers or the general population as a whole. The present study sought to clarify whether smokers and non-smokers differ in cardiovascular reactivity to challenge, or in patterns of reactivity to repeated challenge. 28 smokers and 28 anthropometrically matched non-smokers underwent repeated cardiovascular reactivity assessment. Results suggest that smokers had higher diastolic blood pressure (DBP) than non-smokers, and that female non-smokers demonstrated DBP response sensitization. Findings highlight direct associations between smoking and cardiovascular reactivity of potential significance to the etiology of cardiovascular disease.

RESUMEN

Social support is believed to benefit cardiovascular health in part by buffering recipients from life stress. Classically, this has been investigated by exploring the relationship between support and cardiovascular reactivity to laboratory stress. Such research customarily emphasizes stress responses and downplays the relevance of resting cardiovascular levels. However, it is now appreciated that resting cardiovascular function is associated with disease risk independently of reactivity. Moreover, such mechanisms are known to be relevant to female members of the population, despite the fact that much previous research has focused on males. Reactivity research rests on the assumption that stress promotes gradual hypertension over time. As such, it is important to establish the relationship between psychosocial factors and resting blood pressure. In a cross-sectional biopsychosocial screening study, we examined resting cardiovascular levels in 211 healthy non-smoking women, using regression to assess associations with psychometric indices of social support (namely, perceived network size and perceived satisfaction with support) while controlling for a range of potential biometric and psychometric confounds. Overall, social support was found to be associated with reduced resting cardiovascular function independently of, and to a greater extent than, biometric variables, anxiety, and depression. Benchmarking these effects against the differences in cardiovascular function between the present sample and a group of 92 similarly aged males revealed that social support accounted for as much variance as gender, which is widely assumed to be an important biomedical determinant of blood pressure. Such findings corroborate assertions that social support influences disease risk in ways that involve direct psychosomatic mechanisms.
