Of Sound Heart and Mind: A Scoping Review of Risk and Protective Factors for Symptoms of Depression, Anxiety, and Posttraumatic Stress in People With Heart Disease.

BACKGROUND: Heart disease is related to the etiology of mental health problems such as depression, anxiety, and posttraumatic stress. OBJECTIVE: The goal of this scoping review was to determine which factors pose a significant risk for the onset of symptoms of depression, anxiety, and posttraumatic stress in patients with heart disease, as well as to identify what might protect them from these afflictions. METHOD: We conducted a thorough search of relevant medical and psychological databases (Scopus, PsycARTICLES, Psychology and Behavioral Sciences Collection, Sage Journals, and MEDLINE) and identified 41 studies that met inclusion criteria, which included all types of heart disease. RESULTS: The results of our review indicate that mental health history, the tendency to stifle negative emotional experiences (known as "type D personality"), and social support in patients with heart disease are related to the onset of or protection from depression, anxiety, and posttraumatic stress. These factors, along with gender and younger age, seem to be relatively consistent predictors of mental health problems in this population. CONCLUSIONS: As per our results, it is important for clinicians to attend to the mental health history, type D personality, and presence and quality of social support in patients with heart disease. More research into prevention and gender differences is necessary to hone the detection and treatment of these problems in people with heart disease. CLINICAL IMPLICATIONS: Attention to their mental health history, their ability to express and regulate affect, their age, and their gender will most likely assist in identifying symptoms of depression, anxiety, and posttraumatic stress in people with cardiac disease. Gender differences, particularly in the manifestation of depression, ought to be taken into account.

Optical Clearing Agents for Optical Imaging Through Cartilage Tympanoplasties: A Preclinical Feasibility Study.

HYPOTHESIS: Optical clearing agents (OCAs) can render cartilage tympanoplasty grafts sufficiently transparent to permit visualization of middle ear structures in an operated ear using optical coherence tomography (OCT) imaging. METHODS: Pieces of human tragal cartilage were treated with glycerol, a commonly used OCA. A reference reflector was imaged with OCT through the tympanoplasty as it cleared and the optical attenuation of the graft was measured. The reversibility of clearing and the dimensional changes associated with glycerol absorption were also measured. In a separate experiment, a human cadaveric temporal bone was prepared to simulate an ossiculoplasty surgery with cartilage replacement of the tympanic membrane. A partial ossicular replacement prosthesis (PORP) inserted in the ear was imaged with OCT through a 0.4mm cartilage graft optically cleared with glycerol. MAIN OUTCOME MEASURE: The optical attenuation of 0.4mm cartilage grafts decreased at 2.3+/-1.1 dB/min following treatment with glycerol, reaching a total decrease in attenuation of 13.6+/-5.9 dB after 7 minutes. The optical and dimensional effects of glycerol absorption were reversable following saline washout. In the temporal bone preparation, treatment of a cartilage graft with glycerol resulted in a 13 dB increase in signal-to-noise ratio and a 13 dB increase in contrast for visualizing the PORP through the graft with OCT. CONCLUSIONS: Optical clearing agents offer a potential pathway towards optical coherence tomography imaging of the middle ear in post-surgical ears with cartilage grafts.

Evaluation of fluorodeoxyglucose positron-emission tomography with computed tomography for staging of urothelial carcinoma.

OBJECTIVE: To investigate the role of (18) F-fluorodeoxyglusose positron-emission tomography (FDG-PET), combined with computed tomography (CT) and forced diuresis, in the staging and follow-up of urothelial carcinoma (UC). PATIENTS AND METHODS: We recruited 44 patients with muscle-invasive urothelial bladder cancer (UBC) before radical cystectomy (RC), 19 under follow-up after RC and seven after systemic chemotherapy. For those who had RC, histopathology was used as the reference standard to compare the sensitivity and specificity of FDG-PET/CT and standard CT in detecting UBC and pelvic lymph node metastasis. Furthermore, 36 patients with ≥ 6 months of follow-up imaging were considered to describe the progression of UC and extrapelvic positive FDG-PET/CT images. RESULTS: For the detection of primary UBC, FDG-PET/CT was slightly more sensitive than CT (85% vs 77%) but less specific (25% vs 50%). For the detection of pelvic node metastasis FDG-PET/CT was more sensitive than CT (57% vs 33%) with a specificity of 100% for both imaging techniques. In 20 patients, extrapelvic FDG-PET/CT images showed suspected disease at the first evaluation. UC progressed in nine of the 10 patients who had synchronous multiple PET-positive retroperitoneal or mediastinal lymph nodes, and in only two of the nine with unique hyperactive lesions in the lung. FDG-PET/CT also detected a pT1G3 UC of the renal pelvis and all bone metastases detected by bone scintigraphy. CONCLUSIONS: FDG-PET/CT could replace standard CT and bone scintigraphy in the presurgical staging and monitoring of patients with UC after surgery or chemotherapy.

Outpatient management of pediatric acute mastoiditis.

OBJECTIVE: Evaluate the Montreal Children's Hospital experience with outpatient management of uncomplicated acute mastoiditis with parenteral antibiotic therapy alone and determine if it is a safe alternative to inpatient management. SUBJECTS AND METHOD: A retrospective review of pediatric patients diagnosed with acute mastoiditis at a tertiary care pediatric hospital between 2013 and 2015 was performed. Patients with syndromes, immunodeficiency, cholesteatoma, chronic otitis media, cochlear implant in the affected ear, or incidental mastoid opacity were excluded. RESULTS: 56 children age 6 months to 15 years old were treated for acute mastoiditis, including 29 hospitalizations and 27 outpatients. Patients managed as outpatient with daily intravenous ceftriaxone had a 93% cure rate. Eighteen hospitalized and one outpatient had complications of acute mastoiditis. Children with complications were more likely to be febrile (p = 0.045). Two patients failed outpatient therapy and were admitted; one for myringotomy and piperacillin-tazobactam treatment and one required a mastoidectomy. 4/27 children treated as outpatient underwent myringotomy and tube insertion, 2 underwent myringotomy and tube along with admission and 21 did not require tube insertion. The average total duration of intravenous antibiotic therapy was respectively 4.9 and 18.9 days in the outpatient and hospitalized group. The average duration of admission was 5.9 days. CONCLUSION: Outpatient medical therapy of uncomplicated pediatric mastoiditis is safe, successful, and efficient. Benefits include efficient use of surgical beds, cost savings and patient and family convenience. Careful patient selection and close monitoring are keys for successful outcome.

Predictive factors for sentinel lymph nodes and non-sentinel lymph nodes metastatic involvement: a database study of 1,041 melanoma patients.

BACKGROUND: Sentinel lymph node (SLN) biopsy may identify patients who may need completion lymphadenectomy and adjuvant therapy. METHODS: Univariate and multivariate analysis were conducted for SLN status in a prospective cohort of 1,041 patients. A biopsy was recommended for melanoma greater than or equal to 1 mm thick or greater than or equal to .75 mm with poor prognostic features. RESULTS: For sentinel node status, mitotic rate is very significant in univariate analysis. In multivariate analysis, Breslow, lymphovascular invasion, and primary site were significant. Breslow thickness greater than or equal to 2 mm and SLN with macroscopic burden greater than or equal to 2 mm are the only statistically significant variables predicting the non-SLN status in multivariate analysis. CONCLUSIONS: The data confirm the importance of Breslow, lymphovascular invasion, and body site for SLN status. The cutoff of 2 mm for tumor load in SLN appears to be a simple technique to find the high-risk patients with further lymph node disease.

Functional avoidance of lung in plan optimization with an aperture-based inverse planning system.

PURPOSE: To implement SPECT-based optimization in an anatomy-based aperture inverse planning system for the functional avoidance of lung in thoracic irradiation. MATERIAL AND METHODS: SPECT information has been introduced as a voxel-by-voxel modulation of lung importance factors proportionally to the local perfusion count. Fifteen cases of lung cancer have been retrospectively analyzed by generating angle-optimized non-coplanar plans, comparing a purely anatomical approach and our functional approach. Planning target volume coverage and lung sparing have been compared. Statistical significance was assessed by a Wilcoxon matched pairs test. RESULTS: For similar target coverage, perfusion-weighted volume receiving 10 Gy was reduced by a median of 2.2% (p=0.022) and mean perfusion-weighted lung dose, by a median of 0.9 Gy (p=0.001). A separate analysis of patients with localized or non-uniform hypoperfusion could not show which would benefit more from SPECT-based treatment planning. Redirection of dose sometimes created overdosage regions in the target volume. Plans consisted of a similar number of segments and monitor units. CONCLUSIONS: Angle optimization and SPECT-based modulation of importance factors allowed for functional avoidance of the lung while preserving target coverage. The technique could be also applied to implement PET-based modulation inside the target volume, leading to a safer dose escalation.
