RESUMO

OBJECTIVES: To evaluate demographic and clinical characteristics, treatment patterns, and quality of life in patients with locally advanced or metastatic urothelial carcinoma in Asia. METHODS: Data were drawn from the Adelphi Real World Metastatic Urothelial Carcinoma Disease Specific Programme™, a cross-sectional survey of medical oncologists/urologists and their adult patients in Saudi Arabia, South Korea, Taiwan, and Turkey. Exploratory patient-reported outcomes included the EQ-5D visual analog scale, European Organisation for Research and Treatment of Cancer Quality of Life of Patient Questionnaire global health, and Brief Pain Inventory. Analyses were descriptive. RESULTS: Overall, 175 physicians reported data for 988 patients. Mean (standard deviation) patient age was 66.3 (10.8) years, 77% were men, and 82% had bladder tumors at diagnosis. Of patients receiving first- (n = 988), second- (n = 290), and third-line (n = 87) treatments, 81%, 35%, and 59% received chemotherapy, respectively, and 17%, 63%, and 34% received programmed cell death protein 1/ligand 1 inhibitors, respectively. Patient-reported (n = 319) mean (standard deviation) EQ-5D visual analog scale score was 51.8 (15.6), European Organisation for Research and Treatment of Cancer Quality of Life of Patient Questionnaire global health status score was 44.6 (19.9), and Brief Pain Inventory score was 6.5 (1.9; n = 315). CONCLUSION: The most common first- and second-line treatments for locally advanced or metastatic urothelial carcinoma were chemotherapy and programmed cell death protein 1/ligand inhibitors, respectively. At third line, 10% of patients received best supportive care alone, underscoring an unmet need for effective third-line treatment options. Patients in all regions reported quality-of-life impairment.

RESUMO

OBJECTIVE: Primary progressive multiple sclerosis (PPMS) does not respond well to immunomodulatory or immunosuppressive treatment. Chronic activation of microglia has been implicated in the pathophysiology of PPMS. The antimalarial drug hydroxychloroquine (HCQ) reduces the activity of human microglia and has neuroprotective effects in vitro. METHODS: We conducted a single-arm, phase II futility trial of 200 mg oral HCQ twice daily for 18 months. In an effort to investigate disability worsening in the absence of overt focal inflammation, we excluded participants with contrast enhancing lesions on a screening magnetic resonance imaging (MRI). The primary end point was ≥20% worsening on the timed 25-foot walk measured between 6 and 18 months of follow-up. RESULTS: Based on original trial data, 40% of the cohort were expected to worsen. We used a Simon 2-stage design to compare a null hypothesis of 40% of the cohort worsening against the one-sided alternative of 20%. Using a 5% type 1 error rate and 80% power, HCQ treatment would be deemed successful if fewer than 10 of 35 participants experienced clinically significant worsening. The study met its primary end point, as only 8 of 35 participants worsened between 6 and 18 months. HCQ was overall well-tolerated, with adverse events in 82% and serious adverse events in 12% of participants. All serious adverse events were unlikely related to HCQ use. INTERPRETATION: HCQ treatment was associated with reduced disability worsening in people with PPMS. HCQ is a promising treatment candidate in PPMS and should be investigated further in randomized controlled clinical trials. ANN NEUROL 2021;90:940-948.

RESUMO

INTRODUCTION: This study evaluated the trends in orthodontic practitioner choice over the past 15 years and explored the lay public's understanding of different orthodontic practitioner options in the U.S., specifically, orthodontists compared with general dentists. METHODS: A survey was distributed to a representative sample of laypersons in the U.S. The response rate was 90.2%, and 727 completed responses were analyzed. RESULTS: A 28.2% shift away from orthodontists toward general dentists over the last 15 years was significant (P <0.001). The 2 most frequently endorsed ways respondents found their orthodontic practitioners were a recommendation from another dentist (54.2%) and their family's general dentist who offered orthodontic treatment in-house (22.9%). Respondents' knowledge of orthodontists was limited; 85.0% believed that dentists who perform orthodontic treatment are also orthodontic specialists. Only 17.1% of respondents disagreed with the statement that "a dentist who advertises orthodontic treatment is an orthodontic specialist." In addition, 89.7% were not aware that a dentist could not be called an orthodontist without separate training from an accredited residency program. Finally, 64.2% of respondents did not know that an orthodontist must complete more education than a general dentist. CONCLUSIONS: Over the past 15 years, the percentage of orthodontic patients treated by general dentists has increased significantly. The public's ability to differentiate between different types of orthodontic practitioners is poor, showing substantial confusion about orthodontists' qualifications. Most respondents believed that orthodontists are best suited for their orthodontic treatment, but they rely heavily on their general dentists for orthodontic practitioner decisions.

RESUMO

Technology has transformed almost every aspect of our lives. Smartphones enable patients to request, receive, and transmit information irrespective of the time and place. The global pandemic has forced healthcare providers to employ technology to aid in 'flattening the curve. The Novel Coronavirus, which is responsible for COVID-19, is transmitted primarily through person-to-person contact but may also be spread through aerosol generating procedures, so many clinics have severely limited interpersonal interactions. The purpose of this article is to provide helpful information for those orthodontists considering some form of remote practice. Various HIPAA-compliant telecommunication or teledentistry systems that can be used for orthodontic treatment are introduced and discussed. Detailed information about each platform that can potentially be used for orthodontics is provided in Figure 1. The authors do not endorse any of the products listed and the included software is not all inclusive but instead is a glimpse into the options available.

RESUMO

AIM: To validate the total illness burden index for prostate cancer (TIBI-CaP) in castration-resistant prostate cancer (CRPC) patients. PATIENTS & METHODS: Baseline comorbidity scores collected using the TIBI-CaP were compared with the baseline patient-reported health-related quality of life using the SF-12v2 and FACT-P questionnaires in 302 patients enrolled in the Treatment Registry for Outcomes in CRPC Patients (TRUMPET). RESULTS: Baseline TIBI-CaP scores were negatively correlated with all baseline SF-12v2 domain/composite (p < 0.001) and FACT-P subscale/total (p < 0.020) scores. There was a significant decreasing linear trend in SF12v2 and FACT-P scores over the categories based on TIBI-CaP quartiles of comorbidity burden (from 'least' to 'severe'). CONCLUSION: The TIBI-CaP is a valid measure of comorbidity burden in patients with CRPC in the real world.

RESUMO

Cyclophosphamide is a chemotherapeutic agent which was first discovered in experimental tumours in rats, and it has since been widely used to treat malignancies and severe manifestations of various auto-immune diseases. High-dose chemotherapy and continuous daily oral regimens are associated with significant toxicity profiles, but i.v. pulsed regimens have lowered the rates of adverse effects in rheumatological studies. Cyclophosphamide has been shown to be useful in the treatment of severe autoimmune conditions due to its powerful immunosuppressive ability; however, it remains a relatively underused modality in dermatology. This article reviews the current literature on cyclophosphamide and its clinical applications in dermatology.

RESUMO

Mycosis fungoides is the most common subtype of primary cutaneous lymphoma and has several clinical variants. We report a 74-year-old man presenting with an acquired palmoplantar keratoderma initially diagnosed and treated as psoriasis with suboptimal improvement. Several months later the patient developed patches and plaques that were histologically consistent with mycosis fungoides. These lesions were ameliorated with the treatment of the underlying mycosis fungoides and the palmoplantar keratoderma resolved promptly with radiotherapy. This case highlights the importance of considering mycosis fungoides as an infrequent but serious cause of acquired palmoplantar keratoderma.

RESUMO

Controllable/escapable tailshocks (ESs) do not produce the behavioral and neurochemical outcomes produced by equal yoked uncontrollable/inescapable tailshocks (ISs). The prelimbic cortex is known to play a key role in mediating the protective effects of control. The concepts of act/outcome learning and control seem similar, and act/outcome learning is mediated by a circuit involving the prelimbic cortex and posterior dorsomedial striatum (DMS). Thus, we tested the involvement of the DMS in the protective effect of ES, in rats. First, we examined Fos immunoreactivity in both the DMS and dorsolateral striatum (DLS) after ES and yoked IS. We then investigated the effect of blocking DMS or DLS N-methyl-d-aspartate receptors with the specific antagonist D-(-)-2-amino-5-phosphopentanoic acid (D-AP5) on the release of dorsal raphe nucleus serotonin (5-HT) during ES, as well as on the level of anxiety produced by the ES experience 24 h later. ES, but not yoked IS, produced a large increase of Fos activity in the DMS. Consistent with the Fos data, D-AP5 in the DMS, but not in the DLS, prevented the inhibition of dorsal raphe nucleus 5-HT release normally produced by ES. Furthermore, D-AP5 administered into the DMS before ES, but not into the DLS, increased anxiety 24 h later, leading to levels similar to those produced by IS. These results suggest that, as with appetitive act/outcome contingency learning, the protective effects of behavioral control over a stressor require the DMS.

RESUMO

Allograft rejection is common following clinical organ transplantation, but defining specific immune subsets mediating alloimmunity has been elusive. Calcineurin inhibitor dose escalation, corticosteroids, and/or lymphocyte depleting antibodies have remained the primary options for treatment of clinical rejection episodes. Here, we developed a highly multiplexed imaging mass cytometry panel to study the immune response in archival biopsies from 79 liver transplant (LT) recipients with either no rejection (NR), acute T cell-mediated rejection (TCMR), or chronic rejection (CR). This approach generated a spatially resolved proteomic atlas of 461,816 cells (42 phenotypes) derived from 96 pathologist-selected regions of interest. Our analysis revealed that regulatory (HLADR+ Treg) and PD1+ T cell phenotypes (CD4+ and CD8+ subsets), combined with variations in M2 macrophage polarization, were a unique signature of active TCMR. These data provide insights into the alloimmune microenvironment in clinical LT, including identification of potential targets for focused immunotherapy during rejection episodes and suggestion of a substantial role for immune exhaustion in TCMR.

RESUMO

OBJECTIVE: The aim of this study was to generate real-world evidence documenting use of prescription and nonprescription therapies recorded by health care providers for women experiencing vasomotor symptoms (VMS) associated with menopause. METHODS: This noninterventional, retrospective, observational cohort study used data from US patient medical records. Participating health care providers were gynecologists, internal medicine/family physicians, or advanced practice providers who typically saw three or more women per week presenting with menopausal symptoms and could identify eligible medical records; providers were recruited from local medical association directories and from listings from previously conducted research. Eligible women presented January 2016 through December 2019, were 40 to 60 years of age, and reported experiencing bothersome hot flashes at least twice within 24 hours. RESULTS: A total of 283 health care providers provided data for 1,016 women. The most common symptoms at initial presentation were hot flashes (91.2%), sleep problems (49.9%), and vaginal dryness (47.0%). At least one therapy for menopausal symptoms was recorded for 883 women (86.9%), and 611 (60.1%) had documentation of prescription medication, most commonly hormone therapy (70.4%). Nearly 40% of women had no prescription medication documented, and approximately 13% had no therapy documented. Despite experiencing bothersome menopausal symptoms, approximately 50% delayed seeking care for more than 6 months. Women had a mean of 2.1 (SD, 2.0) office visits related to menopause from initial presentation to completion of review, and health care resource utilization did not vary by treatment status. Subgroup analyses indicated nominal differences in treatment use across ethnic groups and varying prescribing patterns for menopausal symptoms by practitioner type and US region. CONCLUSIONS: A high proportion of women with VMS remain untreated even when experiencing bothersome symptoms of menopause. Improved management of VMS is required to provide relief from the symptoms effectively and safely.

RESUMO

OBJECTIVE: To document health care providers' views regarding treatments for symptoms associated with menopause and discussions with patients about symptoms and treatment decisions. Results informed development of a data collection form for a retrospective medical record review (reported separately). METHODS: Registered US gynecologists or primary care providers from all US regions were identified from local association directories and an in-house database and were invited to participate in a qualitative interview if they consulted with three or more patients per week presenting with menopausal symptoms. Participants provided demographic data, information about patients' symptoms, and health care provider and patient views on prescription and nonprescription therapies. Key concepts/themes from interviews were identified. RESULTS: Participating health care providers (10 gynecologists, 10 primary care providers) agreed there are effective treatment options for menopausal symptoms, particularly vasomotor symptoms and vaginal dryness and/or atrophy. Health care providers reported that treatment was generally dictated by symptoms that interfered with quality of life and/or daily activities, although patients often had symptoms for months before presentation. All health care providers said they prescribe hormone and/or nonhormone therapies for treatment of menopausal symptoms; half stated that they typically inquire about patients' nonprescription therapy use, and 45% recommend specific nonprescription therapies. The most commonly cited barriers to initiation of any therapy for menopausal symptoms were patient concerns about risks and financial considerations (ie, insurance or cost). CONCLUSIONS: US health care providers reported prescribing therapies for menopausal symptoms and noted that these therapies were perceived as generally effective; however, barriers to initiation of prescription therapy exist, and new treatment options are needed.

RESUMO

Allograft rejection is a frequent complication following solid organ transplantation, but defining specific immune subsets mediating alloimmunity has been elusive due to the scarcity of tissue in clinical biopsy specimens. Single cell techniques have emerged as valuable tools for studying mechanisms of disease in complex tissue microenvironments. Here, we developed a highly multiplexed imaging mass cytometry panel, single cell analysis pipeline, and semi-supervised immune cell clustering algorithm to study archival biopsy specimens from 79 liver transplant (LT) recipients with histopathological diagnoses of either no rejection (NR), acute T-cell mediated rejection (TCMR), or chronic rejection (CR). This approach generated a spatially resolved proteomic atlas of 461,816 cells derived from 98 pathologist-selected regions of interest relevant to clinical diagnosis of rejection. We identified 41 distinct cell populations (32 immune and 9 parenchymal cell phenotypes) that defined key elements of the alloimmune microenvironment (AME), identified significant cell-cell interactions, and established higher order cellular neighborhoods. Our analysis revealed that both regulatory (HLA-DR+ Treg) and exhausted T-cell phenotypes (PD1+CD4+ and PD1+CD8+ T-cells), combined with variations in M2 macrophage polarization, were a unique signature of TCMR. TCMR was further characterized by alterations in cell-to-cell interactions among both exhausted immune subsets and inflammatory populations, with expansion of a CD8 enriched cellular neighborhood comprised of Treg, exhausted T-cell subsets, proliferating CD8+ T-cells, and cytotoxic T-cells. These data enabled creation of a predictive model of clinical outcomes using a subset of cell types to differentiate TCMR from NR (AUC = 0.96 ± 0.04) and TCMR from CR (AUC = 0.96 ± 0.06) with high sensitivity and specificity. Collectively, these data provide mechanistic insights into the AME in clinical LT, including a substantial role for immune exhaustion in TCMR with identification of novel targets for more focused immunotherapy in allograft rejection. Our study also offers a conceptual framework for applying spatial proteomics to study immunological diseases in archival clinical specimens.

RESUMO

OBJECTIVE: This study investigated the prevalence and impact of moderate to severe vasomotor symptoms (VMS), related treatment patterns, and experiences in women. METHODS: The primary objective was to assess the prevalence of moderate to severe menopause-related VMS among postmenopausal women aged 40 to 65 years in Brazil, Canada, Mexico, and four Nordic European countries (Denmark, Finland, Norway, and Sweden) using an online survey. Secondary objectives assessed impact of VMS among perimenopausal and postmenopausal women with moderate to severe VMS using the Menopause-Specific Quality of Life questionnaire, Work Productivity and Activity Impairment questionnaire, Patient-Reported Outcomes Measurement Information System sleep disturbances assessment, and questions regarding treatment patterns and attitudes toward symptoms and available treatments. RESULTS: Among 12,268 postmenopausal women, the prevalence of moderate to severe VMS was about 15.6% and was highest in Brazil (36.2%) and lowest in Nordic Europe (11.6%). Secondary analyses, conducted among 2,176 perimenopausal and postmenopausal women, showed that VMS affected quality of life across all domains measured and impaired work activities by as much as 30%. Greater symptom severity negatively affected sleep. Many women sought medical advice, but most (1,238 [56.9%]) were not receiving treatment for their VMS. The majority (>70%) considered menopause to be a natural part of aging. Those treated with prescription hormone therapy and nonhormone medications reported some safety/efficacy concerns. CONCLUSIONS: Among women from seven countries, moderate to severe menopause-related VMS were widespread, varied by region, and largely impaired quality of life, productivity, and/or sleep.

RESUMO

Background: The incidence and mortality rate of men with prostate cancer have been increasing in Asia. ELIGARD® is a formulation of leuprorelin acetate whose safety and efficacy have been well-established in Western regions. However, limited safety data are available for Asian populations. Methods: ELIGANT (ELIGard AsiaN sTudy) was a Phase 4, multicenter, prospective, single-arm, interventional study. Men with locally advanced or metastatic prostate cancer without concomitant chemotherapy, or another androgen receptor pathway inhibitor, were enrolled across Asia to receive ELIGARD® (22.5 mg subcutaneous depot injection) every 3 months for 15 months, with a follow-up visit at 18 months. The primary objective was to establish the safety of ELIGARD® in Asian men with hormone-dependent prostate cancer. The secondary objectives were to assess efficacy, via prostate-specific antigen (PSA) progression and testosterone levels, and health-related quality of life (HRQoL). Results: In total, 106 patients were included in the safety analysis set (SAF). The most common treatment-emergent adverse events (TEAEs) included PSA increase, cough, back pain, hot flush, anemia, and upper respiratory tract infection. TEAEs considered related to ELIGARD® were reported in 13.2% of patients (n=14), two of which were serious. In the full analysis set (FAS) (n=105), 81.2% (n=56) and 68.5% (n=61) of patients achieved a PSA reduction of ≥90% from baseline at 12 and 18 months, respectively. At 18 months, the numbers of patients with testosterone levels <20, 20-50, and >50 ng/dL were 65 (61.9%), 17 (16.2%), and two (1.9%), respectively; 20% had missing testosterone measurements. HRQoL remained stable throughout the study with minimal change from baseline at study completion. Conclusions: In conclusion, the safety profile of ELIGARD® (22.5 mg) in Asian men with hormone-dependent prostate cancer is comparable to previous studies in Western regions. Trial Registration: Clinical trial registration number NCT03035032.

RESUMO

This study describes an automatic technique to accurately determine the maximum head circumference (MHC) measurement from MRI studies within the Picture Archiving and Communications System, and can automatically add this measurement to the final radiology report. Participants were selected through a retrospective chart review of patients referred to the neurosurgery clinic. Forty-nine pediatric patients with ages ranging from 5 months to 11 years were included in the study. We created 14 printed ring structures to mirror the head circumference values at various ages along the x-axis of the Nellhaus chart. The 3D-printed structures were used to create MRI phantoms. Analytical obtainment of circumference values from the 3D objects and phantom images allowed for a fair estimation and correction of errors on the image-based-measuring instrument. Then, standard manual MHC measurements were performed and compared to values obtained from the patients' MRI T1 images using the tuned instrument proposed in this document. A T-test revealed no statistical difference between the manual assessments and the ones obtained by the automation p = 0.357, α = 0.05. This automatic application augments the more error-prone manual MHC measurement, and can add a numerical value to the final radiology report as a standard application.

RESUMO

Recent advances in technology, growing patient demand, and the need for social distancing due to Coronavirus Disease 2019 has expedited adoption of teledentistry in orthodontics as a means of consulting and monitoring a patient without an in-office visit. However, a lack of computer literacy and knowledge of software choices, and concerns regarding patient safety and potential infringement of regulations can make venturing into this new technology intimidating. In this article, various types of teledentistry systems for orthodontic practices, implementation guidelines, and important regulatory considerations on the use of teledentistry for orthodontic purposes are discussed. A thorough evaluation of the intended use of the software should precede commitment to a service. Selected service should be Health Insurance Portability and Accountability Act compliant at minimum and a Business Associate Agreement should be in place for protection of privacy. Ensuring the compatibility of the designated clinic computer with the system's requirements and installation of all safeguards must follow. Appointments should be documented in the same manner as in-office visits and teledentistry patients must be located within the clinician's statutory license boundary. Informed consent forms should include teledentistry or a supplemental teledentistry consent form should be used. Malpractice insurance covers everything usual and customary under the provider's license but the need for cyber liability insurance increases with teledentistry.
