BACKGROUND The combination of anti-epidermal growth factor receptor(EGFR)therapy and chemotherapy is currently a preferred first-line treatment for patients with unre-sectable,RAS and BRAF wild-type,left-sided metastatic colorectal cancer(mCRC).Several studies have also demonstrated the benefit of anti-EGFR therapy in sub-sequent line settings for this patient population.However,direct evidence com-paring the effectiveness of frontline vs subsequent anti-EGFR therapy remains limited,leaving a crucial gap in guiding optimal treatment strategies.AIM To compare overall survival(OS)between frontline and subsequent anti-EGFR treatment in patients with unresectable,RAS and BRAF wild-type,left-sided mCRC.METHODS We retrospectively reviewed the medical records of mCRC patients treated at The King Chulalongkorn Memorial Hospital and Songklanagarind Hospital,Thailand,between January 2013 and April 2023.Patients were classified into two groups based on the sequence of their anti-EGFR treatment.The primary endpoint was OS.RESULTS Among 222 patients with a median follow-up of 29 months,no significant difference in OS was observed between the frontline and subsequent-line groups(HR 1.03,95%CI:0.73-1.46,P=0.878).The median OS was 35.53 months(95%CI:26.59-44.47)for the frontline group and 31.60 months(95%CI:27.83-35.37)for the subsequent-line group.In the subsequent-line group,71 patients(32.4%)who ultimately never received anti-EGFR therapy had a significantly worse median OS of 19.70 months(95%CI:12.87-26.53).CONCLUSION Frontline and subsequent-line anti-EGFR treatments provide comparable OS in unresectable,RAS/BRAF wild-type,left-sided mCRC patients,but early exposure is vital for those unlikely to receive subsequent therapy. 展开更多

The role of autologous hematopoietic stem cell transplantation(auto-HSCT)following high-dose chemotherapy has been validated and accepted as a standard treatment for patients with relapsed diffuse large B-cell lymphoma(DLBCL).However,its clinical efficacy as frontline therapy remains to be elucidated.This study aimed to examine the feasibility of frontline auto-HSCT for newly diagnosed intermediate/high-risk DLBCL patients.We retrospectively reviewed the data of 223 patients treated with frontline auto-HSCT or chemotherapy alone(year 2008-2014)from four hospitals.The median follow-up time was 29.4 months.Between the two treatment arms among the intermediate/high-risk DLBCL patients,the 3-year overall survival(OS)and progression-free survival(PFS)rates of patients given frontline auto-HSCT were 87.6%and 81.9%,respectively,and the chemotherapy-alone group showed 3-year OS and PFS rates of 64.9%and 59.59%,respectively.Compared with the chemotherapy-alone group,the frontline auto-HSCT could eliminate the adverse impact of non-germinal center B-cell(GCB)type.In addition,in the frontline auto-HSCT group,patients who achieved complete response(CR)at auto-HSCT had a longer survival time than those who did not achieve CR.Our results suggested that frontline auto-HSCT could improve the prognosis of intennediate/high-risk DLBCL patients. 展开更多

BACKGROUND Frontline nurses in Wuhan directly fighting severe acute respiratory syndrome coronavirus-2 diseases are at a high risk of infection and are extremely susceptible to psychological stress,especially due to the global coronavirus disease 2019(COVID-19)pandemic.The psychological after-effects of this public health emergency on frontline nurses will last for years.AIM To assess factors influencing post-traumatic stress disorder(PTSD)among frontline nurses in Wuhan 6 mo after the COVID-19 pandemic began.METHODS A total of 757 frontline nurses from five hospitals in Wuhan,China,participated in an online survey from July 27 to August 13,2020.This cross-sectional online study used a demographic information questionnaire,the PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders,the Connor-Davidson Resilience Scale,and the Patient Health Questionnaire-4.The chisquare test and logistic regression were used to analyze the association of demographics,COVID-19-related variables,and PTSD.Logistic regression was also conducted to investigate which variables were associated with PTSD outcomes.RESULTS A total of 13.5%,24.3%,and 21.4%of the frontline nurses showed symptoms of PTSD,depression,and anxiety,respectively.The multivariate logistic regression analysis showed that the following factors were strongly associated with PTSD:Having a relative,friend,or colleague who died of COVID-19;experiencing stigma;or having psychological assistance needs,depressive symptoms or anxiety.Showing resilience and receiving praise after the COVID-19 outbreak were protective factors.CONCLUSION Frontline nurses still experienced PTSD(13.5%)six months after the COVID-19 outbreak began.Peer support,social support,official recognition,reward mechanisms,exercise,better sleep,and timely provision of information(such as vaccine research progress)by the government via social media,and adequate protective supplies could mitigate the level of PTSD among nurses responding to COVID-19.Stigmatization,depression,and anxiety might be associated with a greater risk of PTSD among nurses. 展开更多

Like soldiers,frontline medical staff provide a first line of defense and have played a critical role in responses to the outbreak of coronavirus disease-2019 in December 2019.It is important to acknowledge the considerable pressure placed on frontline medical staff in the face of a new type of coronavirus that is highly infectious and for which no specific treatment is available.Here,we review the various kinds of psychological problems afflicting frontline medical staff who are combatting the severe acute respiratory syndrome epidemic.These include anxiety,insomnia,depression,interpersonal difficulties,and post-traumatic stress disorder syndrome.We further present a summary of countermeasures for alleviating these problems based on our findings.These countermeasures include ensuring the provision of adequate protective gear for frontline medical staff,developing timely and clear guidelines,strengthening social support,and providing clear criteria and additional training,focusing on the choice of frontline medical staff.An understanding of the psychological impacts of an epidemic situation and of relevant countermeasures will contribute to reducing the psychological pressures on frontline medical staff.Consequently,they will be able to cope better with outbreaks of infectious diseases in the future,to reduce the psychological pressure of the front-line medical staff,and to improve the treatment level. 展开更多

The objective of the study was to compare the efficacy of one topical insecticide-acaricide (Frontline Tri-Act?) and of one collar (Seresto?) against fleas (Ctenocephalides felis) and ticks (Rhipicephalus sanguineus) on dogs exposed to bi-weekly water showering. Twenty four (24) dogs were enrolled in the study. A first set of 16 dogs were acclimatised to their cages from Day 1 to 7 and a second set of 8 dogs from Day 163 to Day 169. The 24 dogs were randomly allocated to three groups (1 to 3). Dogs assigned to Group 1 were not treated and served as negative controls. Dogs assigned to Group 2 received the Seresto? collar on Day 0 and dogs in Group 3 received Frontline Tri-Act? on Days 170 and 198. The dogs were observed hourly for four hours after treatment administration for possible adverse reactions. Dogs in Groups 1 and 2 underwent water showering on Days 14, 28, 42, 56, 70, 84, 98, 112, 126, 143 and 157. Dogs in all groups underwent water showering on Days 173, 185, 199 and 213. Dogs were infested with approximately 100 (±4) adult, unfed C. felis fleas only on Days 177, 190, 203, and 217, in alternance with infestations with 50 adult unfed R. sanguineus on Days 182, 196, 210, and 224, to assess sustained efficacy. Fleas and ticks were removed and counted on 24 and 48 hours ± 2 hours after each infestation, respectively. Frontline Tri-Act? was >99% effective against C. felis following an initial and a second monthly administration on dogs that were water showered bi-weekly. The Seresto? collar was from 68.3% to 92.9% effective against C. felis Days 178 to 218 after collar administration. Frontline Tri-Act? was effective from 87.8% to 100% against ticks whereas Seresto collar was effective from 82.2% to 94.2% from Day 184 to Day 226. 展开更多

Background:While quantitative research has determined that emotional distress and psychiatric illness among frontline healthcare workers increased with the COVID-19 pandemic,detailed qualitative data describing their personal experiences are needed in order to make appropriate plans to address provider mental health in future pandemics.This study aims to further explore the psychological effects of the pandemic on COVID-19 ICU clinicians and administrators through focus groups.Methods:Two separate 2-h focus groups of physicians were conducted,one with frontline faculty clinicians and another with administrators.Qualitative data analysis was conducted.Results:In September and November 2023,volunteer samples were recruited from the pulmonary and critical care medicine division of The University of Texas Southwestern physicians who served during the pandemic primarily as clinicians(N=6)or in major administrative roles(N=5).Perceptions of both administrators’and clinicians’pandemic experiences were coded into the same 7 qualitative themes:planning,sense of community and isolation,disparities and inequalities,communication and listening,leadership,effects of the pandemic,and emotional/psychiatric/coping responses.Effects of the pandemic were the most coded theme in both groups;second was disparities and inequalities for clinicians and pandemic planning for administrators.Thematic content is summarized separately for clinicians and administrators,illustrated with representative quotes.Conclusion:This study adds detailed qualitative findings to enrich existing quantitative knowledge on frontline COVID-19 workers’emotional responses.Both clinicians and administrators identified helpful and non-helpful institutional responses.These findings are consistent with prior studies of disaster worker experiences and may help to inform efforts to address provider mental health in future pandemics. 展开更多
