RESUMEN

BACKGROUND: Stigma against lesbian, gay, bisexual or queer (LGBQ) people may increase their risk of mental illness and reduce their access to and/or benefit from evidence-based psychological treatments. Little is known about the feasibility, acceptability and effectiveness of adapted psychological interventions for sexual minority individuals in the UK. AIMS: To describe and evaluate a novel LGBQ Wellbeing group therapy for sexual minority adults experiencing common mental health problems, provided in a UK Improving Access to Psychological Therapies (IAPT) service. METHOD: An eight-session LGBQ Wellbeing group intervention was developed drawing on CBT and LGBQ affirmative principles. We compare the socio-demographic and clinical characteristics of patients who completed and dropped out of the groups, and explore changes in self-reported symptoms of depression, anxiety and functional impairment. RESULTS: Over eight courses provided, 78 service-users attended at least one session, of whom 78.2% completed the intervention (drop-out rate 21.8%). Older participants were more likely to drop out. There was a lower proportion of female and bisexual or ethnic/racial minority individuals than would be expected. There were significant reductions in severity of depression, anxiety and functional impairment following the group, and more than half of those who completed the intervention needed no further treatment. CONCLUSIONS: There was preliminary evidence of the feasibility of, and potential clinical benefit in, a group therapy intervention for sexual minority adults experiencing common mental health problems. Future research should investigate access and outcomes for participants with additional social disadvantage, e.g. those who are female, older, bisexual or ethnic/racial minority.

RESUMEN

PURPOSE: The purpose of this study was to investigate the prognostic value of whole-body metabolic tumor volume (MTV) and other metabolic tumor parameters, obtained from baseline and first restaging 18F-FDG PET/CT scans in melanoma patients treated with immune checkpoint inhibitors (ICIs). METHODS: Eighty-five consecutive melanoma patients (M, 57; F, 28) treated with ICIs who underwent PET/CT scans before and approximately 3 months after the start of immunotherapy were retrospectively enrolled. Metabolic tumor parameters including MTV for all melanoma lesions were measured on each scan. A Cox proportional hazards model was used for univariate and multivariate analyses of metabolic parameters combined with known clinical prognostic factors associated with overall survival (OS). Kaplan-Meier curves for patients dichotomized based on median values of imaging parameters were generated. RESULTS: The median OS time in all patients was 45 months (95% CI 24-45 months). Univariate analysis demonstrated that MTV obtained from first restaging PET/CT scans (MTVpost) was the strongest prognostic factor for OS among PET/CT parameters (P < 0.0001). The median OS in patients with high MTVpost (≥ 23.44) was 16 months (95% CI 12-32 months) as compared with more than 60 months in patients with low MTVpost (< 23.44) (P = 0.0003). A multivariate model including PET/CT parameters and known clinical prognostic factors revealed that MTVpost and the presence of central nervous system lesions were independent prognostic factors for OS (P = 0.0004, 0.0167, respectively). One pseudoprogression case (1.2%) was seen in this population and classified into the high MTVpost group. CONCLUSION: Whole-body metabolic tumor volume from PET scan acquired approximately 3 months following initiation of immunotherapy (MTVpost) is a strong prognostic indicator of OS in melanoma patients. Although the possibility of pseudoprogression must be considered whenever evaluating first restaging PET imaging, it only occurred in 1 patient in our cohort.

RESUMEN

OBJECTIVES: Provision of personalised care planning is a national priority for people with dementia. Research suggests a lack of quality and consistency of care plans and reviews. The PriDem model of care was developed to deliver feasible and acceptable primary care-based postdiagnostic dementia care. We aimed to increase the adoption of personalised care planning for people with dementia, exploring implementation facilitators and barriers. DESIGN: Mixed-method feasibility and implementation study. SETTING: Seven general practices from four primary care networks (PCNs) in the Northeast and Southeast of England. PARTICIPANTS: A medical records audit collected data on 179 community-dwelling people with dementia preintervention, and 215 during the intervention year. The qualitative study recruited 26 health and social care professionals, 14 people with dementia and 16 carers linked to participating practices. INTERVENTION: Clinical dementia leads (CDL) delivered a 12-month, systems-level intervention in participating PCNs, to develop care systems, build staff capacity and capability, and deliver tailored care and support to people with dementia and their carers. PRIMARY AND SECONDARY OUTCOME MEASURES: Adoption of personalised care planning was assessed through a preintervention and postintervention audit of medical records. Implementation barriers and facilitators were explored through semistructured qualitative interviews and non-participant observation, analysed using codebook thematic analysis informed by Normalisation Process Theory. RESULTS: The proportion of personalised care plans increased from 37.4% (95% CI 30.3% to 44.5%) preintervention to 64.7% (95% CI 58.3% to 71.0%) in the intervention year. Qualitative findings suggest that the flexible nature of the PriDem intervention enabled staff to overcome contextual barriers through harnessing the skills of the wider multidisciplinary team, delivering increasingly holistic care to patients. CONCLUSIONS: Meaningful personalised care planning can be achieved through a team-based approach. Although improved guidelines for care planning are required, commissioners should consider the benefits of a CDL-led approach. TRIAL REGISTRATION NUMBER: ISRCTN11677384.

RESUMEN

OBJECTIVES: To evaluate the feasibility and acceptability of a primary care-based intervention for improving post-diagnostic dementia care and support (PriDem), and implementation study procedures. DESIGN: A non-randomised, mixed methods, feasibility study. SETTING: Seven general practices from four primary care networks (PCNs) in the Northeast and Southeast of England. PARTICIPANTS: We aimed to recruit 80 people with dementia (PWD) and 66 carers INTERVENTION: Clinical Dementia Leads delivered a 12-month intervention in participating PCNs, to develop care systems, build staff capacity and capability, and deliver tailored care and support to PWD and carers. OUTCOMES: Recruitment and retention rates were measured. A mixed methods process evaluation evaluated feasibility and acceptability of the intervention and study procedures. Using electronic care records, researchers extracted service use data and undertook a dementia care plan audit, preintervention and postintervention, assessing feasibility of measuring the primary implementation outcome: adoption of personalised care planning by participating general practices. Participants completed quality of life, and service use measures at baseline, 4 and 9 months. RESULTS: 60 PWD (75% of recruitment target) and 51 carers (77% of recruitment target) were recruited from seven general practices across four PCNs. Retention rate at 9 months was 70.0% of PWD and 76.5% of carers. The recruitment approach showed potential for including under-represented groups within dementia. Despite implementation challenges, the intervention was feasible and acceptable, and showed early signs of sustainability. Study procedures were feasible and accessible, although researcher capacity was crucial. Participants needed time and support to engage with the study. Care plan audit procedures were feasible and acceptable. CONCLUSIONS: The PriDem model is an acceptable and feasible intervention. A definitive study is warranted to fully inform dementia care policy and personalised dementia care planning guidance. Successful strategies to support inclusion of PWD and their carers in future research were developed. TRIAL REGISTRATION NUMBER: ISRCTN11677384.

RESUMEN

OBJECTIVE: To show that augmented reality (AR) visualization of single-photon emission computed tomography (SPECT)/computed tomography (CT) data in 3D can be used to accurately localize targets in the head and neck region. MATERIALS AND METHODS: Eight head and neck styrofoam phantoms were painted with a mixture of radioactive solution (Tc-99m) detectable with a handheld gamma probe and fluorescent ink visible only under ultraviolet (UV) light to create 10-20 simulated lymph nodes on their surface. After obtaining SPECT/CT images of these phantoms, virtual renderings of the nodes were generated from the SPECT/CT data and displayed using a commercially available AR headset. For each of three physician evaluators, the time required to localize lymph node targets was recorded (1) using the gamma probe alone and (2) using the gamma probe while wearing the AR headset. In addition, the surface localization accuracy when using the AR headset was evaluated by measuring the misalignment between the locations visually marked by the evaluators and the ground truth locations identified using UV stimulation of the ink at the site of the nodes. RESULTS: For all three evaluators, using the AR headset significantly reduced the time to detect targets (P = 0.012, respectively) compared to using the gamma probe alone. The average misalignment between the location marked by the evaluators and the ground truth location was 8.6 mm. CONCLUSION: AR visualization of SPECT/CT data in 3D allows for accurate localization of targets in the head and neck region, and may reduce the localization time of targets.

RESUMEN

PURPOSE: To evaluate the diagnostic performance and clinical utility of 18F-fluciclovine PET/CT in patients with biochemical recurrence (BCR) of prostate cancer (PC). METHODS: 18F-Fluciclovine scans of 165 consecutive men with BCR after primary definitive treatment with prostatectomy (n = 102) or radiotherapy (n = 63) were retrospectively evaluated. Seventy patients had concurrent imaging with at least one other conventional modality (CT (n = 31), MRI (n = 31), or bone scan (n = 26)). Findings from 18F-fluciclovine PET were compared with those from conventional imaging modalities. The positivity rate and impact of 18F-fluciclovine PET on patient management were recorded. In 33 patients who underwent at least one other PET imaging (18F-NaF PET/CT (n = 12), 68Ga-PSMA11 PET/CT (n = 5), 18F-DCFPyL PET/CT (n = 20), and 68Ga-RM2 PET/MRI (n = 5)), additional findings were evaluated. RESULTS: The overall positivity rate of 18F-fluciclovine PET was 67 %, which, as expected, increased with higher prostate-specific antigen (PSA) levels (ng/ml): 15 % (PSA < 0.5), 50 % (0.5 ≤ PSA < 1), 56 % (1 ≤ PSA < 2), 68 % (2 ≤ PSA < 5), and 94 % (PSA ≥ 5), respectively. One hundred and two patients (62 %) had changes in clinical management based on 18F-fluciclovine PET findings. Twelve of these patients (12 %) had lesion localization on 18F-fluciclovine PET, despite negative conventional imaging. Treatment plans of 14 patients with negative 18F-fluciclovine PET were changed based on additional PET imaging with a different radiopharmaceutical. CONCLUSION: 18F-Fluciclovine PET/CT remains a useful diagnostic tool in the workup of patients with BCR PC, changing clinical management in 62 % of participants in our cohort.

RESUMEN

Our purpose was to investigate the prognostic value of 18F-FDG PET/CT parameters in melanoma patients before beginning therapy with antibodies to the programmed cell death 1 receptor (anti-PD-1). Methods: Imaging parameters including SUVmax, metabolic tumor volume, and the ratio of bone marrow to liver SUVmean (BLR) were measured from baseline PET/CT in 92 patients before the start of anti-PD-1 therapy. The association with survival and imaging parameters combined with clinical factors was evaluated. Clinical and laboratory data were compared between the high-BLR group (>median) and the low-BLR group (≤median). Results: Multivariate analyses demonstrated that BLR was an independent prognostic factor for progression-free and overall survival (P = 0.017 and P = 0.011, respectively). The high-BLR group had higher white blood cell counts and neutrophil counts and a higher level of C-reactive protein than the low-BLR group (P < 0.05). Conclusion: Patients with a high BLR were associated with poor progression-free and overall survival, potentially explained by evidence of systemic inflammation known to be associated with immunosuppression.

RESUMEN

Presurgical planning and communication between the prosthodontist and the surgeon is essential to achieve optimal placement of functional implants. Besides the basic clinical examination and the use of mounted study casts, radiographic imaging is an essential adjunctive aid in treatment planning. In the past decade, multiplanar reformatted computerized tomography (CT) has become the most comprehensive and accurate aid for implant treatment planning. Available software programs allow precise assessment of the 3-dimensional architecture and internal anatomy of the jaws. The programs enable accurate preoperative evaluation for planning implant placement with a maximum use of bone. However, the accurate transfer of the implant analysis from 2- and 3-dimensional computer reconstruction to the surgical site was not predictable until recently. As advancements occurred in technology with the advent of the helical CT scanner and rapid prototype 3-dimensional model production by stereolithography, a CAD-CAM program was developed to create an accurate transfer from the image to the surgical site. Detailed preoperative analyses of the quantity and quality of bone as well as the ideal positioning of implant fixtures may be established with the aid of a surgical guide that is placed directly on the bone for precise implant insertion.

RESUMEN

PURPOSE: The purpose of this article is to present an overview of the epidemiology diagnosis, and management of bladder cancer, with a focus on the early stage of this disease. OVERVIEW: English-language articles published between 1990 and 2000, as well as selected abstracts published in non-English languages before 1990, were reviewed. Epidemiologic data clearly indicate that bladder cancer is much more common in men, White persons, and the elderly. Cigarette smoking appears to be the most significant environmental risk factor. Screening for the disease is currently not standard in the United States or Canada. Potential tests include urine cytology, hematuria dipstick, and the urinary biomarkers. Diagnosis is made most often on the basis of the findings of cystoscopy, tumor biopsy, and urine cytology. Transurethral resection (TUR) of the tumor is generally the first-line treatment for superficial disease. Cystectomy is the "gold standard" treatment for invasive disease in many countries, although trimodality therapy (TUR, radiation, systemic chemotherapy) has shown promise as a bladder-preserving strategy. Intravesical therapy is effective for preventing disease recurrence, although its role in slowing disease progression is uncertain. Chemotherapy and radiation also can be used with cystectomy to treat or prevent pelvic recurrence of invasive disease or to prolong life in patients with metastatic disease. CLINICAL IMPLICATIONS: Bladder cancer is a commonly occurring disease. Prevention efforts must focus on the avoidance or cessation of cigarette smoking and on public education relating to known environmental risk factors. Patient and disease factors must be considered in making treatment decisions and determining prognosis. Careful follow-up after treatment is essential. It is hoped that ongoing research on potential tumor markers and tumor-specific therapies ultimately will result in improved clinical outcomes for patients with this malignancy.
