RESUMO

Background: This phase II study evaluated the efficacy and safety of the histone deacetylase (HDAC) inhibitor, vorinostat, administered in combination with paclitaxel and carboplatin in patients with platinum sensitive recurrent ovarian cancer. Methods: Women with recurrent platinum-sensitive ovarian, peritoneal, or Fallopian tube carcinoma, a performance status of 0-2, and good overall organ function were eligible. Patients received 6 courses of paclitaxel (175 mg/m2) and carboplatin area under the curve (AUC) of 5.0 mg/mL/min administered via intravenous infusion on day 1 of a 3-week schedule. In addition, patients received vorinostat 400 mg orally once daily on days -4 through 10 of Cycle 1 and days 1 through 14 of each subsequent treatment cycle. The primary endpoints were progression-free survival (PFS) and adverse events. The secondary endpoints were the objective response rate and overall survival. Results: Fifty-five patients were included. CR was obtained in 14 patients (26.4%) and PR in 19 patients (35.8%), resulting in an ORR of 62.2%. Twenty patients (37.7%) had SD. The median duration of response (DoR) was 12.6 (range 6-128) months. The median PFS was 11.6 months (95% CI, 10.3-18.0; p < 0.001). Median OS was 40.6 months (95% Cl, 25.1-56.1). The most common treatment-related adverse events (all grades) were fatigue, anemia, thrombocytopenia, neutropenia, anorexia, nausea, pain, sensory neuropathy, myalgia, stomatitis and diarrhea. Conclusions: Vorinostat combined with carboplatin plus paclitaxel was tolerable and generated significant responses including a long median overall survival in recurrent platinum-sensitive ovarian cancer.

RESUMO

BACKGROUND: Optimal management of allergic rhinitis requires patient education with easy access to accurate information. However, previous online platforms have provided misleading information. The demand for online medical information continues to grow, especially with the introduction of advanced chatbots like ChatGPT. METHODS: This study aimed to evaluate the quality of information provided by ChatGPT regarding allergic rhinitis. A Likert scale was used to assess the accuracy of responses, ranging from 1 to 5. Four authors independently rated the responses from a healthcare professional's perspective. RESULTS: A total of 20 questions covering various aspects of allergic rhinitis were asked. Among the answers, eight received a score of 5 (no inaccuracies), five received a score of 4 (minor non-harmful inaccuracies), six received a score of 3 (potentially misinterpretable inaccuracies) and one answer had a score of 2 (minor potentially harmful inaccuracies). CONCLUSIONS: The variability in accuracy scores highlights the need for caution when relying solely on chatbots like ChatGPT for medical advice. Patients should consult qualified healthcare professionals and use online sources as a supplement. While ChatGPT has advantages in medical information delivery, its use should be approached with caution. ChatGPT can be useful for patient education but cannot replace healthcare professionals.

RESUMO

BACKGROUND: Patient education is a key element in the management of asthma. AIMS: This study aimed to evaluate the popularity and usefulness of YouTube videos on asthma. METHODS: Two authors screened and evaluated the 200 most popular videos. Data on likes, dislikes, views, comment, source of uploader, days since upload, and usefulness were recorded and included for analyses. The usefulness of the videos was categorized as follows: useful, misleading, or neutral. Misleading videos provided at least one scientifically incorrect detail, whereas useful videos contained scientifically correct information. RESULTS: A total of 130 videos were included, and the total number of views was 100,290,242 with a total duration of 29 h and 8 min. While 26.6% of videos were uploaded by TV shows and YouTube channels, only 7.7% were uploaded by lung specialists. 65.4% of the videos contained scientifically correct information, whereas 18.5% contained misleading information. Although videos from medical professionals had a higher quality than videos from YouTube channels and TV shows, the latter were more popular. Misleading videos had numerically, but not statistically significant higher views compared with useful videos. CONCLUSIONS: YouTube videos on asthma are popular in terms of viewer interaction, and the popularity is not restricted to videos uploaded by professional sources. Although more than half of the videos were found to be useful, a non-negligible proportion of videos were assessed as misleading. The usefulness of YouTube videos on asthma is variable and initiatives should be taken to increase the potential of YouTube as an useful source in patient education.

RESUMO

BACKGROUND: The use of social media as a source of health information is increasing, and the usefulness of the content may vary depending on the specific disease. Thus, this study was designed to assess the content, viewer engagement and usefulness of the most viewed YouTube videos on lung cancer. METHODS: 167 videos were reviewed, and 143 met the eligibility criteria. Two authors evaluated the videos separately, and data on views, likes, dislikes and comments were extracted, and data on the source of uploader, duration and content quality were recorded. RESULTS: 89 videos (62%) were classified as useful, 8 (6%) as misleading and 46 (32%) as neither. The misleading videos were significantly more popular in terms of views and likes compared with the useful videos: 845 643 versus 81 700, P = 0.003 and 12 170 versus 415, P < 0.001, respectively. CONCLUSIONS: This study shows that YouTube videos on lung cancer are popular and that around two-thirds of the videos are useful in terms of patient education. However, the misleading videos are currently attracting higher viewer interaction and might compose a future challenge in terms of the spread of misinformation as the algorithms will prioritize popular videos rather than videos with evidence-based information.

RESUMO

BACKGROUND: Allergic rhinitis is a very common chronic condition that affects nearly one-quarter of the adult population worldwide. The optimal management of allergic rhinitis includes useful information on several aspects of the condition. Social media and online platforms are increasingly being used to obtain health-related information. OBJECTIVE: The study aimed to evaluate and evaluate the popularity and usefulness of YouTube videos on allergic rhinitis. METHODS: Out of 225 screened videos, 86 met the inclusion criteria. A scoring scheme was designed to evaluate and rate the content of the extracted data. Data on views, likes, dislikes, and comments were extracted, and data on the source of uploader, duration, and content quality were recorded. RESULTS: A total of 43% of the videos were classified as useful, 36% as misleading, and 21% as neither useful nor misleading. Although professional health care providers uploaded two-thirds of the videos, they accounted for only 24.4% of the total videos. Videos uploaded by television shows and YouTube channels had by far the most user interaction, accounting for 66.9% of the total likes, 66.8% of the total dislikes, and 54.0% of the total comments. This source alone accounted for 23.4% of the total views, but for 48% of the total misleading videos. CONCLUSION: The usefulness of YouTube videos on allergic rhinitis is varying and less than half of the videos provided useful information. If the proper conditions are met, selected YouTube videos on allergic rhinitis can be used as a source of information for patient education.

RESUMO

BACKGROUND: Impairments in mechanisms underlying early information processing have been reported in posttraumatic stress disorder (PTSD); however, findings in the existing literature are inconsistent. This current study capitalizes on technological advancements of research on electroencephalographic event-related potential and applies it to a novel PTSD population consisting of trauma-affected refugees. METHODS: A total of 25 trauma-affected refugees with PTSD and 20 healthy refugee controls matched on age, gender, and country of origin completed the study. In two distinct auditory paradigms sensory gating, indexed as P50 suppression, and sensorimotor gating, indexed as prepulse inhibition (PPI), startle reactivity, and habituation of the eye-blink startle response were examined. Within the P50 paradigm, N100 and P200 amplitudes were also assessed. In addition, correlations between psychophysiological and clinical measures were investigated. RESULTS: PTSD patients demonstrated significantly elevated stimuli responses across the two paradigms, reflected in both increased amplitude of the eye-blink startle response, and increased N100 and P200 amplitudes relative to healthy refugee controls. We found a trend toward reduced habituation in the patients, while the groups did not differ in PPI and P50 suppression. Among correlations, we found that eye-blink startle responses were associated with higher overall illness severity and lower levels of functioning. CONCLUSIONS: Fundamental gating mechanisms appeared intact, while the pattern of deficits in trauma-affected refugees with PTSD point toward a different form of sensory overload, an overall neural hypersensitivity and disrupted the ability to down-regulate stimuli responses. This study represents an initial step toward elucidating sensory processing deficits in a PTSD subgroup.

RESUMO

AIM: To provide a general overview of the current biological treatments and discuss their potential anti-asthmatic effects. DATA SOURCES: We reviewed articles in PubMed found using the search words "Asthma/therapy AND antibodies, monoclonal/therapeutic use AND cytokines." STUDY SELECTIONS: Only articles published in English since 2000 were considered. The search identified 29 studies; 8 additional studies were found by hand search, generating 37 studies. RESULTS: Of the 37 studies investigating biological treatments of asthma, 5 were on the effects of anti-IgE (omalizumab); 12 on anti-IL-5; 8 on anti-IL-13; 5 on anti-IL-4R-α; 3 on anti-IL-9; one on TNF-α; one on anti-IL-2R-α; one on TSLP (Thymic Stromal Lymphopoietin); and one on OX40L. Sample sizes ranged from 3 to 943 participants. Studies of therapies targeting IgE, IL-2, IL4R-α, IL-5, and IL-13 showed some efficacy, whereas those targeting TSLP, IL-9, and TNF-α lacked convincing effectiveness. CONCLUSION: Research on the biological treatment of asthma shows promising results. While anti-IgE (omalizumab) has been used in the treatment of asthma for some years, anti-IL-5 has recently been approved for use. The efficacy of results of other large studies with a longer duration is needed to draw a firm conclusion. Such studies should not only focus on clinical outcomes, but also consider asthma-related quality of life. Knowledge on the asthma phenotypes and identification of biomarkers associated with these will be useful for physicians considering the right treatment for the asthma patient.
