Improving Compliance to Follow-Up Care After Primary Emergency Department Ophthalmic Consultation.

PURPOSE: To identify factors that affect the likelihood of follow-up after emergency department (ED) visit for ophthalmic complaints and to evaluate a protocol to improve compliance. DESIGN: Prospective interventional study with historical controls. METHODS: This study was conducted at Jamaica Hospital Medical Center in Jamaica, New York. The study population included 962 patients who presented to the ED and who required ophthalmology consultation. Participants in the control group were given only verbal follow-up instructions. Participants in the intervention group were given verbal instructions, written instructions, telephone calls, and, if not responding to calls, a mailed letter. The primary outcome was the overall follow-up rate. Secondary outcomes were follow-up rate by demographic subgroup. RESULTS: Patients in the intervention group were significantly more likely to follow up (68.8% vs 42.9%, P < .001). Nearly all subgroups exhibited significantly improved follow-up with the intervention, with the exception of patients 18 to 29 years of age, patients with diagnosis severity class III, patients with no insurance, patients with hospital financial aid, patients paying with workers' compensation, and patients with an unknown employment status. CONCLUSIONS: Before the intervention, most patients receiving ophthalmology consultation in the ED did not return for follow-up care. These patients tended to be young, unemployed, uninsured or use hospital financial aid, were in the control group, had good visual acuity, reported no change in vision, and had a condition that was not vision-threatening. Follow-up rates were improved in nearly all subgroups by providing written instructions, telephone calls, and mailed letters. Such instructions should be considered in similar populations.

Topical cenegermin associated ocular surface and contact lens drug precipitate deposit formation.

Purpose: To report for the first time drug precipitate deposit formation on both the ocular surface and bandage contact lens (BCL) of a patient treated with topical cenegermin. Observations: A patient suffering from stage III neurotrophic keratitis developed extensive ocular surface and BCL deposits over the eight week course of her topical cenegermin therapy. The ocular surface deposits were weakly adherent, detaching and clearing from the cornea within minutes of BCL removal. They reappeared rapidly and repeatedly however after each of five BCL exchanges. Symptom wise, the patient was unaware of their presence. Of historical note, this patient: (1) developed BCL ciprofloxacin deposits while undergoing a traditional neurotrophic keratitis treatment regimen, (2) did not develop corneal drug precipitate deposits within the placebo arm of the cenegermin clinical trial (vehicle only without cenegermin or BCL), and (3) did not develop corneal deposits with a latter BCL-free cenegermin treatment course. Conclusions and Importance: Topical cenegermin can produce extensive drug precipitate deposits on both the ocular surface and contact lens when used in conjunction with a bandage contact lens. Such deposits: (1) may represent an esthetic issue only as at least in our patient they were not symptom provoking, questionably interfered with the clinical course of the cenegermin therapy and did not require drug cessation, (2) may implicate both contact lenses and high frequency drug application as previously unidentified but formal risk factors for drug precipitate deposit formation, and (3) may act as a time-release medication reservoir enhancing drug delivery and long-term treatment efficacy.

More positive group memberships are associated with greater resilience in Royal Air Force (RAF) personnel.

In the current project, we examined how perceived group memberships (number, and characteristics, of), social and relational identification, and social identity leadership are associated with resilience in Royal Air Force (RAF) personnel. Based on social identity theorizing, we hypothesized positive associations between the number of groups, perceptions of their characteristics (e.g., positivity), and how they relate to each other (i.e., compatibility) and resilience (H1). We also hypothesized positive associations between both social identity leadership (H2) and resilience, and social and relational identification (H3) and resilience. Two hundred and forty-three personnel from 18 RAF bases completed an identity mapping exercise and measures of leadership, social and relational identification, and resilience. Our findings highlighted the importance of the association between positive group memberships and resilience, and social identification and resilience. Counter to our hypothesis, belonging to more groups was negatively associated with resilience, and there were non-significant relationships between three principles of social identity leadership and resilience, with embedding identity being significantly negatively associated with resilience. In support of social identity theorizing, the number of positive groups was positively associated with resilience, as was social identification. These findings indicate that, for RAF personnel, it is belonging to positive groups, both within and outside work, along with social identification, that is positively associated with resilience.

Analysis of Compensatory Corneal Epithelial Thickness Changes in Keratoconus Using Corneal Tomography.

PURPOSE: To determine patterns of epithelial remodeling in keratoconus and to assess changes in these patterns as the disease progresses. METHODS: This is a prospective case series. Patients with keratoconus undergoing corneal collagen crosslinking underwent Scheimpflug imaging before and after epithelial debridement. Analysis was performed to determine maps of epithelial thickness and change in keratometry. Maps were analyzed for patterns, and map SD was quantified. Measures were compared across the patients as grouped by the severity of disease. RESULTS: The study comprised 38 eyes from 30 patients. Patients were stratified using the Amsler-Krumeich classification of keratoconus severity, with 17, 14, and 7 patients in the stage I, stage II, and stage III groups, respectively. A pattern of central epithelial thinning (to approximately 20 µm) with an annulus of epithelial thickening (to approximately 30-40 µm) was demonstrated. Changes were more pronounced in the later stages of the disease, with the average central thickness decreasing from 23 µm in stage I to 18 µm in stage III. Central corneal steepening of 1.5 to 1.9 diopters and peripheral flattening of 1.4 to 2.0 diopters after epithelial debridement were demonstrated. Analysis of map SD revealed a significant difference between stage III patients and patients at earlier stages of disease. CONCLUSIONS: The "doughnut pattern" of epithelial remodeling in keratoconus is supported by Scheimpflug imaging. This pattern is demonstrated to partially compensate for central corneal steepening seen in keratoconus.

High-speed spectral nanocytology for early cancer screening.

High-throughput partial wave spectroscopy (HTPWS) is introduced as a high-speed spectral nanocytology technique that utilizes the field effect of carcinogenesis to perform minimally invasive cancer screening on at-risk populations. HTPWS uses fully automated hardware and an acousto-optic tunable filter to scan slides at low magnification, to select cells, and to rapidly acquire spectra at each spatial pixel in a cell between 450 and 700 nm, completing measurements of 30 cells in 40 min. Statistical quantitative analysis on the size and density of intracellular nanostructures extracted from the spectra at each pixel in a cell yields the diagnostic biomarker, disorder strength (Ld). Linear correlation between Ld and the length scale of nanostructures was measured in phantoms with R2=0.93. Diagnostic sensitivity was demonstrated by measuring significantly higher Ld from a human colon cancer cell line (HT29 control vector) than a less aggressive variant (epidermal growth factor receptor knockdown). Clinical diagnostic performance for lung cancer screening was tested on 23 patients, yielding a significant difference in Ld between smokers and cancer patients, p=0.02 and effect size=1.00. The high-throughput performance, nanoscale sensitivity, and diagnostic sensitivity make HTPWS a potentially clinically relevant modality for risk stratification of the large populations at risk of developing cancer.

A review of cognitive therapy in acute medical settings. Part II: strategies and complexities.

OBJECTIVE: Cognitive therapy (CT) has considerable utility for psychosomatic medicine (PM) in acute medical settings but, to date, no such cohesive adaptation has been developed. Part I delineated a CT model for acute medical settings focusing on assessment and formulation. In Part II, we review how CT can be applied to common PM clinical challenges. A pragmatic approach is helpful because this review targets PM trainees and educators. METHODS: Narrative review is used to discuss the application of CT strategies to common challenges in acute medical settings. Treatment complexities and limitations associated with the PM setting are detailed. Exemplary dialogues are used to model techniques. RESULT: We present CT approaches to eight common scenarios: (1) distressed or hopeless patients; (2) patients expressing pivotal distorted cognitions/images; (3) patients who catastrophize; (4) patients who benefit from distraction and activation strategies; (5) panic and anxiety; (6) suicidal patients; (7) patients who are stuck and helpless; (8) inhibited patients. Limitations are discussed. SIGNIFICANCE OF RESULTS: A CT informed PM assessment, formulation and early intervention with specific techniques offers a novel integrative framework for psychotherapy with the acutely medically ill. Future efforts should focus on dissemination, education of fellows and building research efficacy data.

A review of cognitive therapy in acute medical settings. Part I: therapy model and assessment.

INTRODUCTION: Although cognitive therapy (CT) has established outpatient utility, there is no integrative framework for using CT in acute medical settings where most psychosomatic medicine (P-M) clinicians practice. Biopsychosocial complexity challenges P-M clinicians who want to use CT as the a priori psychotherapeutic modality. For example, how should clinicians modify the data gathering and formulation process to support CT in acute settings? METHOD: Narrative review methodology is used to describe the framework for a CT informed interview, formulation, and assessment in acute medical settings. Because this review is aimed largely at P-M trainees and educators, exemplary dialogues model the approach (specific CT strategies for common P-M scenarios appear in the companion article.) RESULTS: Structured data gathering needs to be tailored by focusing on cognitive processes informed by the cognitive hypothesis. Agenda setting, Socratic questioning, and adaptations to the mental state examination are necessary. Specific attention is paid to the CT formulation, Folkman's Cognitive Coping Model, self-report measures, data-driven evaluations, and collaboration (e.g., sharing the formulation with the patient.) Integrative CT-psychopharmacological approaches and the importance of empathy are emphasized. SIGNIFICANCE OF RESULTS: The value of implementing psychotherapy in parallel with data gathering because of time urgency is advocated, but this is a significant departure from usual outpatient approaches in which psychotherapy follows evaluation. This conceptual approach offers a novel integrative framework for using CT in acute medical settings, but future challenges include demonstrating clinical outcomes and training P-M clinicians so as to demonstrate fidelity.

Helping the clinician help me: towards listening in cancer care.

Despite global support for the ideal of shared decision making, its enactment remains difficult in practice. The UK charity, Macmillan Cancer Support, attempted to incorporate the principles of shared decision making within a programme of distress management in Scotland. Distress management begins by completing the Distress Thermometer (DT). Although the DT is a screening tool, its function in this programme was extended to facilitate collaborative communication within a consultation. The aim of this grounded theory was to analyse the patient experience of the process. Nineteen people underwent semi-structured interviews focused on their experience of distress management. Participants were a mixed-cancer cohort aged 40-79 years. Findings were discussed in a structured manner with a further 14 service users and carers, and 19 clinical specialists in cancer. Constant comparison of all data revealed that the process of positive distress management could best be explained by reference to the core category: 'helping the clinician help me'. The emergence of this core category is detailed by situating its development within the iterative nature of the grounded theory method.

High incidence of migration with poor initial fixation of the Accolade stem.

BACKGROUND: Numerous cementless femoral stem design variations are in clinical use. Because initial implant instability and micromotion are associated with aseptic loosening of the femoral component, migration analysis provides an early assessment of implant survivorship. QUESTIONS/PURPOSES: We determined the (1) migration pattern of the Accolade cementless femoral stem; (2) clinical factors predisposing to stem migration; (3) self-reported patient outcomes; and (4) our current rate of aseptic stem loosening. METHODS: We retrospectively analyzed 81 femoral stems for aseptic migration using Ein-Bild-Roentgen-Analyse-femoral component analysis. Postoperatively, patients completed the WOMAC and SF-12 questionnaires. We assessed radiographic factors potentially associated with subsidence: indices of bone shape and quality, canal fill of the implant, and radiographic signs of loosening. Minimum followup was 24 months (mean, 29 months; range, 24-48 months). RESULTS: The average subsidence at 24 months was 1.3 mm (range, 0-1.5 mm). In the first 2 years, 36% of stems subsided more than 1.5 mm. Large stem size was associated with subsidence. Radiolucent lines (> 1.5 mm in three zones) were present in 10% of stems and associated with lower questionnaire scores. The 5-year survivorship for aseptic loosening of the 367 stems was 97% with revision as end point and 95% for radiographic failure. CONCLUSIONS: The high incidence of migration and stems with radiographic failure raises concerns about patient clinical function and long-term survivorship of this stem design. This migration pattern may be due to poor initial stability with a subsequent lack of osseointegration. Our results differ from radiographic findings and clinical durability of other similar cementless stem designs. LEVEL OF EVIDENCE: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Numerical simulation of partially coherent broadband optical imaging using the finite-difference time-domain method.

Rigorous numerical modeling of optical systems has attracted interest in diverse research areas ranging from biophotonics to photolithography. We report the full-vector electromagnetic numerical simulation of a broadband optical imaging system with partially coherent and unpolarized illumination. The scattering of light from the sample is calculated using the finite-difference time-domain (FDTD) numerical method. Geometrical optics principles are applied to the scattered light to obtain the intensity distribution at the image plane. Multilayered object spaces are also supported by our algorithm. For the first time, numerical FDTD calculations are directly compared to and shown to agree well with broadband experimental microscopy results.

The clinical utility of the distress thermometer: a review.

The Distress Thermometer (DT) is a well validated screening tool, demonstrably sensitive and reasonably specific to the construct of distress in cancer. Its brevity makes it ideal to incorporate into a system of distress management. To ascertain how far this idea has been developed in practice, and to support future research, a literature review was undertaken. Medline, CINAHL, PsycINFO, Embase, ASSIA, British Nursing Index, AMED, CCTR, and HMIC were systematically searched. Forty studies were reviewed that examined the function of the DT alone, together with the problem list (PL), and/or other validated measures. The majority of studies validated the DT against other robust measures of distress in order to establish 'caseness' in these populations, and establish factors associated with distress. Many of the studies recommended that further research should test their findings in clinical practice. A small section of the literature focused on the clinical utility of the DT as a facilitator of consultations, and found it to have potential in this regard. It is concluded that there is enough validation research, and in line with the majority of these studies' recommendations, future research should focus on the utility of DT as part of a structured distress management programme.

The outcomes of palliative care day services: a systematic review.

This systematic review evaluates the evidence underpinning the provision of palliative day care services (PDS) to determine whether such services have a measurable effect on attendees' wellbeing. The majority of studies reviewed were qualitative and elicited individual perceptions of the benefits PDS. Although it was difficult to determine the quality of many studies, it would appear that attendance at PDS had a positive impact on attendees' quality of life. Fewer studies utilized validated outcome measures to determine the effect of PDS on attendees' wellbeing and small sample sizes combined with high attrition rates influenced the significance of some the results. However little quantitative evidence was offered to prove that PDS had an impact on attendees' quality of life or wellbeing. The review concludes that dying people find attending PDS a valuable experience that allows them to engage with others and to be supported in a restorative environment. However, further well-powered empirical studies are required to provide quality evidence to determine whether or not attendance at PDS does indeed have a positive impact on the wellbeing of attendees.

Randomized controlled clinical effectiveness trial of cognitive behavior therapy compared with treatment as usual for persistent insomnia in patients with cancer.

PURPOSE: Persistent insomnia is a common complaint in cancer survivors, but is seldom satisfactorily addressed. The adaptation to cancer care of a validated, cost-effective intervention may offer a practicable solution. The aim of this study was to investigate the clinical effectiveness of protocol-driven cognitive behavior therapy (CBT) for insomnia, delivered by oncology nurses. PATIENTS AND METHODS: Randomized, controlled, pragmatic, two-center trial of CBT versus treatment as usual (TAU) in 150 patients (103 females; mean age, 61 years.) who had completed active therapy for breast, prostate, colorectal, or gynecological cancer. The study conformed to CONSORT guidelines. Primary outcomes were sleep diary measures at baseline, post-treatment, and 6-month follow-up. Actigraphic sleep, health-related quality of life (QOL), psychopathology, and fatigue were secondary measures. CBT comprised five, small group sessions across consecutive weeks, after a manualized protocol. TAU represented normal clinical practice; the appropriate control for a clinical effectiveness study. RESULTS: CBT was associated with mean reductions in wakefulness of 55 minutes per night compared with no change in TAU. These outcomes were sustained 6 months after treatment. Standardized relative effect sizes were large for complaints of difficulty initiating sleep, waking from sleep during the night, and for sleep efficiency (percentage of time in bed spent asleep). CBT was associated with moderate to large effect sizes for five of seven QOL outcomes, including significant reduction in daytime fatigue. There was no significant interaction effect between any of these outcomes and baseline demographic, clinical, or sleep characteristics. CONCLUSION: CBT for insomnia may be both clinically effective and feasible to deliver in real world practice.

Warfarin-induced skin necrosis and heparin-induced thrombocytopenia following mitral valve replacement for marantic endocarditis.

Hemostatic physiology involves a complex interlinking of blood and endothelial factors. Its pharmacological manipulation invariably impacts at multiple molecular sites. Herein is reported an unusual case of coexistent warfarin-induced skin necrosis and heparin-induced thrombocytopenia following mitral valve replacement for thromboembolic phenomena associated with marantic endocarditis and bronchial adenocarcinoma. Thrombophilia in the face of endocarditis should be treated with a suspicion of underlying cancer.

Psychological impact of colostomy pouch change and disposal.

This article presents some of the findings from a multicentre cross-sectional correlational study to evaluate the relationship between colostomy pouch change and disposal practices and the patient's psychological wellbeing. Five questionnaires were used in a one-off interview with 86 patients. Patients were assessed at between one and four months postoperatively. Results from the Pouch Change and Disposal questionnaire showed that only 25% of patients found disposal of used appliances the most difficult part of their pouch change and disposal routine. Half felt that their body was out of their control and 33% reported avoiding social and leisure activities due to what was involved in their pouch change and disposal routine. Patients cited several factors, such as minimizing odour and having an appliance that could flush away, as factors which would help them to stop avoiding these activities. Stoma care nurses have a unique opportunity to improve the psychological wellbeing of their patients by considering the aspects of pouch change and disposal that pose the greatest challenge to individuals. Use of a modified version of the Pouch Change and Disposal questionnaire may be a useful tool in identifying those at risk of impaired quality of life.

The prevalence and moderators of fatigue in people who have been successfully treated for cancer.

OBJECTIVE: The aims of this study were to estimate the prevalence of severe fatigue in disease-free breast cancer patients according to draft International Classification of Disease, Tenth Edition (ICD-10) criteria for cancer-related fatigue (CRF) and to obtain further information on the validity of these criteria. Furthermore, hypotheses derived from psychosocial theories of fatigue regarding the association of fatigue with activity level, psychological distress, and cognitive constructs were also tested. METHODS: Sixty-nine disease-free breast cancer patients were assessed at least 6 months posttreatment, using self-report questionnaires and a structured interview. RESULTS: Nineteen percent of the sample met criteria for CRF. This subgroup differed significantly from the rest of the sample on multiple measures of fatigue and interference. Self-reported activity level bore no relationship to fatigue. Fear of recurrence (FOR) contributed to fatigue indirectly, whilst psychological distress and beliefs about activity appeared to predict fatigue directly. CONCLUSION: The validity of the draft ICD-10 criteria for CRF was supported. Further research is required into the relationship between fatigue, emotional distress, and cognitive-behavioural factors.

A cognitive therapy conceptualization of panic disorder exacerbated by interferon treatment.

This case conference presents a patient with von Willebrand disease, receiving year-long interferon treatment for hepatitis C. She was referred to C-L Psychiatry following a severe exacerbation of panic disorder. Our guest interviewer is Dr. Craig White, a Scottish cognitive therapist. The subsequent discussion outlines the treatment challenges of panic disorder that occurs when a patient is receiving interferon. A literature review evaluates psychological effects of interferon and biological mechanisms by which interferon may exacerbate anxiety and depression. A cognitive therapy conceptualization of interferon-induced exacerbation of panic disorder is proposed.
