Contemporary materialism/consumerism emphasizes excessive spending to own the latest and greatest products. Maintaining an appearance of wealth is economically unfeasible for most. Materialism can generate beliefs of insufficient funds and inadequacy to afford goods. Materialism is the possession of goods for happiness, centrality, and success. Material goods become a focus to someone’s life to signal well-being. Financial scarcity theory explains people believe they are constantly behind or unable to pay for their needs. These individuals will perform tradeoffs to fulfill needs. Perceived lack of finances drives consumers to buy goods that fill perceived deficiencies. Path analysis demonstrated financial scarcity related to higher materialism. Higher financial scarcity related to lower household income and thereby higher materialism. Higher financial scarcity related to higher impression management and thereby higher materialism. These results indicated the possession of goods can artificially inflate someone’s socioeconomic status to compensate for self-perceived paucity.

Objective: Neutrophils produce neutrophil extracellular traps (NETs) by releasing nuclear contents into the extracellular environment. NETs are associated with systemic inflammation and cancer development and progression. We aimed to investigate whether NET markers are associated with the prognosis of endometrial cancer. Methods: Circulating levels of three NET markers (histone-DNA complex, cell-free double-stranded DNA (dsDNA), and neutrophil elastase) were measured in 98 patients with endometrial cancer who underwent surgery as primary treatment between January 2015 and June 2018 and 45 healthy women. Area under the receiver operating characteristic curve (AUC) analyses were conducted to investigate the diagnostic and prognostic utility of the markers for endometrial cancer. Results: Patients with endometrial cancer showed significantly higher levels of the three NET markers than those in healthy controls. In discriminating endometrial cancer patients from healthy controls, the three NET markers showed AUC values in the following order: cell-free dsDNA (0.832; 95 % CI, 0.760–0.889), histone-DNA complex (0.740; 95 % CI, 0.660–0.809), and neutrophil elastase (0.689; 95 % CI, 0.607–0.764), comparable to those of CA-125 (0.741; 95 % CI, 0.659–0.813). Multivariate analysis adjusting for FIGO stage, histology, and lymphovascular space invasion, and lymph node involvement revealed that cell-free dsDNA level (cutoff: 95.2 ng/mL) was an independent prognostic marker for poor progression-free (adjusted HR, 2.75; 95 % CI, 1.096.92; P = 0.032) and overall survival (adjusted HR, 11.51; 95 % CI, 2.0664.22; P = 0.005) for patients with endometrial cancer. Conclusion: High levels of circulating NET markers were observed in patients with endometrial cancer. Cell-free dsDNA levels may play a role as prognostic markers for endometrial cancer.

Abstract Background Less than 1% of studies on child and adolescent health report the involvement of adolescents in health research. This is attributed to barriers experienced by researchers and adolescents in the engagement process. To address this under‐involvement of adolescents, we first need a better understanding of the factors that hinder adolescent involvement in health research. Objective We conducted an umbrella review of reviews to consolidate the review‐level evidence on the barriers to meaningful involvement of adolescents in health research. Methods We preregistered this umbrella review of reviews with PROSPERO (CRD42021287467). We searched 11 databases; Google Scholar; and PROSPERO; supplemented by a hand search of the reference lists of eligible reviews, relevant journals, websites of 472 organisations, and input from experts. This resulted in the inclusion of 99 review articles exploring adolescent involvement in studies on adolescent physical or mental health, which were narratively synthesised. Adolescent coresearchers were engaged at all stages of the review. Results We found that adolescent involvement in health research is impeded by several challenges experienced by researchers and adolescents. Some challenges experienced by researchers were organisational issues which included limited resources, gatekeeping and paying adolescents. Some barriers were related to a lack of preparedness among researchers and included a lack of awareness of adolescent involvement, the need for training and guidance, and negative attitudes towards participatory research. There were also barriers around how adolescents can be involved, such as researchers finding it challenging to adapt to new methods, issues with recruitment and retention of adolescents, inclusiveness and accessibility. There were also challenges specific to adolescents, such as adolescents' skills and expertise, training, motivations and study goals. Finally, barriers related to the ethical involvement of adolescents included issues with power dynamics, confidentiality, safety and protection of adolescents. Some of the barriers reported by adolescents included tokenistic involvement, inaccessibility of adolescent involvement, and their competing demands. Conclusion Researchers may find this review useful in understanding and planning for potential challenges of involving adolescents in research. Despite many identified barriers to adolescent engagement, few mitigation strategies were identified to address these barriers. There is a clear need to establish best practices for meaningful adolescent involvement in health research. Public and Patient Involvement in the Review Adolescents were involved at multiple stages of this umbrella review of reviews. They reviewed the protocol, screened 25% of the articles at title and abstract screening stage, screened 10% of full‐text articles, and worked on data analysis. They also helped plan and conduct a participatory workshop with an adolescent advisory group to discuss the challenges experienced by adolescents in health research.

COVID-19 vaccinations have demonstrated effectiveness in reducing severe infections. However, vaccine hesitancy posed a major public health hurdle to combat the COVID-19 pandemic. Online spread of vaccine conspiracy beliefs generated unwarranted mistrust and resistance to vaccines. While numerous studies have explored the factors influencing vaccine hesitancy, there remains a lack of comprehensive understanding regarding the interplay between perceived disease vulnerability, COVID-19 fear, and vaccine hesitancy. Protection motivation theory posits citizens will evaluate perceived threats and take actions to mitigate potential harm. With a large U.S. sample, path analysis demonstrated individuals’ perceived disease vulnerability was associated with lower vaccine hesitancy. Greater perceived disease vulnerability was associated with higher COVID-19 fear. Greater COVID-19 fear was associated with lower vaccine hesitancy. Greater vaccine conspiracy beliefs associated with higher vaccine hesitancy. However, in the presence of perceived vulnerability to disease, vaccine conspiracy beliefs associated with higher fear of COVID-19 and thereby lower vaccine hesitancy. We found under circumstances of higher perceived vulnerability to disease and fear of COVID-19, vaccine conspiratorial believers were less vaccine hesitant. We discuss how public health messaging can highlight personal risks to contracting COVID-19 to appeal to those who self-identify as disease prone, but may have reservations about vaccines because of misinformation. Successfully combating diseases entails reaching and gaining cooperation from misbelievers because misinformation is expected to continue in the digital age. By understand individual differences to vaccine hesitancy, it can help increase vaccinations and prevent severe illnesses in the post COVID-19 pandemic era.

Adnexal masses detected during pregnancy require a prompt and accurate diagnosis to ensure fetal safety and good oncological outcomes. Computed tomography is the most common and useful diagnostic imaging modality for diagnosing adnexal masses; however, it is contraindicated in pregnant women because of the teratogenic effect of radiation on the fetus. Therefore, ultrasonography (US) is commonly used as the main alternative for the differential diagnosis of adnexal masses during pregnancy. Additionally, magnetic resonance imaging (MRI) can assist in the diagnosis when US findings are inconclusive. As each disease has characteristic US and MRI findings, understanding these features is important for the initial diagnosis and subsequent treatment. Thus, we thoroughly reviewed the literature and summarized the key findings of US and MRI to apply these in real-world clinical practice for various adnexal masses detected during pregnancy.

This study aimed to investigate the efficacy and safety of using optimized parameters obtained by computer simulation for ultrasound-guided high-intensity focused ultrasound (HIFU) treatment of uterine adenomyosis in comparison with conventional parameters. We retrospectively assessed a single-institution, prospective study that was registered at Clinical Research Information Service (CRiS) of Republic of Korea (KCT0003586). Sixty-six female participants (median age: 44 years) with focal uterine adenomyosis were prospectively enrolled. All participants were treated with a HIFU system by using treatment parameters either for treating uterine fibroids (Group A, first 20 participants) or obtained via computer simulation (Group B, later 46 participants). To assess the treatment efficacy of HIFU, qualitative indices, including the clinically effective dysmenorrhea improvement index (DII), were evaluated up to 3 years after treatment, whereas quantitative indices, such as the nonperfused volume ratio and adenomyosis volume shrinkage ratio (AVSR), on MRI were evaluated up to 3 months after treatment. Quantitative/qualitative indices were compared between Groups A and B by using generalized linear mixed effect model. A safety assessment was also performed. Results showed that clinically effective DII was more frequently observed in Group B than in Group A (odds ratio, 3.69; P = 0.025), and AVSR were higher in Group B than in Group A (least-squares means, 21.61; P = 0.001). However, two participants in Group B developed skin burns at the buttock and sciatic nerve pain and required treatment. In conclusion, parameters obtained by computer simulation were more effective than the conventional parameters for treating uterine adenomyosis by using HIFU in terms of clinically effective DII and AVSR. However, care should be taken because of the risk of adverse events.

IntroductionTo evaluate the survival impact of supradiaphragmatic lymphadenectomy as part of debulking surgery in stage IVB ovarian cancer with thoracic lymph node metastasis (LNM).MethodsWe retrospectively enrolled patients diagnosed with stage IVB ovarian, fallopian or primary peritoneal cancer between 2010 and 2020, carrying cardiophrenic, parasternal, anterior mediastinal or supraclavicular lymph nodes ≥5 mm on axial chest computed tomography. All tumors were classified into the abdominal (abdominal tumors and cardiophrenic lymph nodes) and supradiaphragmatic (parasternal, anterior mediastinal or supraclavicular lymph nodes) categories depending on the area involved. Residual tumors were classified into

To successfully understand and shape biodiversity conservation in Alpine grasslands, it is crucial to understand how farmers’ relationship to biodiversity influences their goals and associated practices. We explored how farmers perceive and value biodiversity, how this is related to agricultural and land use practices, and how they view their roles in affecting it. Semi-structured interviews were conducted with 22 farmers in the northern Italian Alps and with 6 experts in the fields of grassland management, agriculture, and environmental conservation in 2020. The farmers’ answers were analyzed using a mental model approach, relational thinking, and the literature on the ‘good farmer’. The experts’ responses were used to discuss and contextualize the farmer’s answers. We found that the farmers’ mental model of biodiversity is associated to different aspects of agricultural management practices and farmers’ roles in mountain agricultural landscapes. Instrumental values of biodiversity are negative and strongly perceived as such by farmers, while relational values associated with biodiversity are positive, but more weakly perceived. These differing perceptions and values seem to be associated with two roles that farmers have, as producers and landscape stewards, and how they value fodder quantity and quality. Most farmers don’t include considerations related to the conservation of biodiversity in their management decisions, and mostly do not envision any changes in biodiversity or management in the future. Effective biodiversity conservation in Alpine grasslands will therefore need to tap into these dual roles and the associated instrumental and relational values of biodiversity for a meaningful dialogue on conservation.

Abstract Background To evaluate the impact of intraoperative hypotension and hemodynamic instability on survival outcomes in patients with high-grade serous ovarian carcinoma (HGSOC). Methods We retrospectively identified patients with HGSOC, who underwent primary or interval debulking surgery between August 2013 and December 2019. We collected anesthesia-related variables, including the arterial blood pressure measurements (at 1-min intervals) during the surgery of patients. The cumulative duration of mean arterial blood pressure (MAP) readings under 65 mmHg and two performance measurements (median performance error [MDPE] and wobble) were calculated. We investigated associations between the factors indicating hemodynamic instability and prognosis. Results In total, 338 patients were included. Based on the cumulative duration of MAP under 65 mmHg, we divided patients into two groups: ≥30 min and

Introduction A lack of awareness on how to engage adolescents in research has been reported as one of the barriers to meaningful youth involvement in health research. Currently, available guidelines on youth involvement are limited in terms of the scope (e.g., focused on limited health research areas), content (e.g., include broad principles) and context (e.g., most guidelines are from high-income countries) for which the guidelines are applicable. To address this, we will develop a set of comprehensive guidelines based on consolidated evidence on youth involvement in health research. To inform these guidelines, we are first conducting an umbrella review to (1) summarise and synthesise findings from reviews on involving adolescents in health research, (2) consolidate the challenges experienced in youth involvement and the recommendations to mitigate these challenges, (3) identify best practices and (4) identify gaps and methodological weaknesses in the extant literature on involving adolescents in health research.Methods and analysis We will include review articles exploring adolescents’ involvement in studies aiming to improve their physical or mental health. Databases to be searched include Cochrane Database of Systematic Reviews, Medical Literature Analysis and Retrieval System Online (MEDLINE), Scopus, Embase, PsycINFO, PsycArticles, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Epistemonikos and Health Systems Evidence. A grey literature search will be conducted in Web of Science, ProQuest, Google Scholar and PROSPERO, supplemented by a handsearch of the reference lists of eligible reviews, relevant journals, websites of related organisations and input from experts. Data will be analysed using narrative synthesis.Ethics and dissemination Ethical approval is not required as we are not collecting participant data as part of this review. The findings of this umbrella review will be disseminated through peer-reviewed publications, participatory workshops and academic conferences.PROSPERO registration number CRD42021287467.

Abstract Lgr5 has been identified as a marker of the stem/progenitor cells in the murine ovary and oviduct by lineage tracing. However, little is known regarding LGR5 expression or its functional significance in human ovary tissues. Here, using RNA in situ hybridization and/or immunohistochemistry, we thoroughly investigated LGR5 expression in normal human ovaries, fallopian tubes and various ovarian tumors. We discovered that LGR5 expression is negligible in the human ovary surface epithelium, whereas ovarian stromal cells normally express low levels of LGR5. Remarkably, fallopian tube epithelium, inclusion cysts and serous cystadenomas with a Müllerian phenotype expressed high levels of LGR5, and LGR5 expression was restricted to PAX8+/FOXJ1− secretory cells of the tubal epithelium. Strong stromal LGR5 expression without epithelial LGR5 expression was consistently observed in the path from serous cystadenoma to serous borderline tumor to low grade serous carcinoma (LGSC). Unlike LGSC, high grade serous carcinoma (HGSC), clear cell carcinoma, endometrioid carcinomas displayed various epithelial-stromal LGR5 expression. Notably, high levels of LGR5 expression were observed in serous tubal intraepithelial carcinoma, which slightly declined in invasive HGSC. LGR5 expression was significantly associated with improved progression-free survival in HGSC patients. Moreover, in vitro assays demonstrated that LGR5 expression suppressed tumor proliferation and migratory capabilities. Taken together, these findings indicate a tumor-suppressive role for LGR5 in the progression of HGSC.

To help inform post-COVID-19 pandemic practical health policies, the researchers created the COVID-19 vaccine misinformation scale (CVMS). During the COVID-19 pandemic, falsehoods spread online which casted doubt and concerns about the vaccine. Example misconceptions included vaccination leads to greater vulnerability to other illness and would alter someone’s DNA. The researchers performed two large surveys with U.S. participants. The researchers reviewed debunked COVID-19 vaccine falsehoods online. Construction of the CVMS followed standard psychometric scale development steps. Statistical analysis provided support for the 10-item CVMS with satisfactory reliability, discriminant validity, and convergent validity. Predictive validity regression analysis demonstrated the CVMS associated with higher vaccine hesitancy. The prevalence of vaccine misbeliefs broadened pandemic healthcare challenges. On top of existing duties, healthcare workers had to explain vaccine efficacy and safety to dispel fallacies. The researchers discuss implications for the CVMS within the context of motivated reasoning theory.

The sociomedical environment is changing. In the traditional physician-patient relationship, the physician was authoritative and the patient was obedient. The contractual relationship featured patient consent to the physician’s decision. Today, the physician must explain fully the planned medical treatment, and any alternative, to the patient, who has the right to choose her treatment after considering the benefits and side-effects. The Korean Society of Gynecologic Oncology thus decided to standardize the surgical consent forms to meet the legal requirements of modern medicine, improve patient understanding of the surgical details, and protect medical staff from legal disputes. To determine the format and content, subcommittees for each cancer type collected and reviewed all relevant articles and the current consent forms of domestic medical institutions. After several meetings, 16 basic items to be included for each type of gynecologic cancer were selected. Also, to help patients understand the surgical details, figures were included. The revised forms were legally reviewed in terms of the appropriateness of the format and content. We also developed English versions to provide adequate information for foreign patients. We hope that these efforts will promote trust between patients and physicians, and contribute to effective treatment by laying a foundation of mutual respect.

Abstract Background The Laparoscopic Approach to Cervical Cancer trial and Surveillance, Epidemiology, and End Results program database study demonstrated that minimally invasive radical hysterectomy was inferior to abdominal radical hysterectomy in terms of disease recurrence and survival. Among risk factors related to poor prognosis after minimally invasive surgery (MIS), tumour spillage during intracorporeal colpotomy became a significant issue. Thus, we designed this trial to evaluate the efficacy and safety of minimally invasive radical hysterectomy using an endoscopic stapler for early-stage cervical cancer. Methods This trial is a prospective, multi-centre, open-label, single-arm, non-inferiority phase II study. The nine organisations will participate in this trial after the approval of the institutional review board. Major eligibility criteria include women aged 20 years or older with cervical cancer stage IB1 squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma according to the revised 2009 FIGO staging system who will undergo type B2 or C hysterectomy by MIS. The primary endpoint is the 4.5-year disease-free survival (DFS) rate between abdominal radical hysterectomy and MIS using an endoscopic stapler. For calculating the sample size, we hypothesised that the 4.5-year DFS rate after MIS using an endoscopic stapler is assumed to be the same after abdominal radical hysterectomy at 90.9%, and the non-inferiority margin was 7.2%. When we consider a three-year accrual and 4.5-year follow-up, at least 13 events must happen, requiring a total of 111 patients assuming a statistical power of 80% and the one-tailed test of 5% significance. A total of 124 patients is needed, considering a drop-out rate of 10%. Discussion We expect intracorporeal colpotomy using an endoscopic stapler may prevent tumour spillage during MIS for stage IB1 cervical cancer, showing a comparable prognosis with abdominal radical surgery. Trial registration ClinicalTrials.gov ; NCT04370496 ; registration date, May 2020.

The study of human microglia function in health and disease is limited by the availability of sound models. Here, the authors develop a method to generate functional microglia in human cortical organoids and investigate the role of human microglia during amyloid beta1-42- induced inflammation.

Abstract Objectives To investigate the impact of computed tomography (CT)-based, artificial intelligence-driven waist skeletal muscle volume on survival outcomes in patients with endometrial cancer. Methods We retrospectively identified endometrial cancer patients who received primary surgical treatment between 2014 and 2018 and whose pre-treatment CT scans were available (n = 385). Using an artificial intelligence-based tool, the skeletal muscle area (cm2) at the third lumbar vertebra (L3) and the skeletal muscle volume (cm3) at the waist level were measured. These values were converted to the L3 skeletal muscle index (SMI) and volumetric SMI by normalisation with body height. The relationships between L3, volumetric SMIs, and survival outcomes were evaluated. Results Setting 39.0 cm2/m2 of L3 SMI as cut-off value for sarcopenia, sarcopenia (

Abstract Background To determine whether additional chemotherapy after concurrent chemoradiation (CCRT) improves survival outcomes in patients with early cervical cancer who undergo radical hysterectomy (RH). Methods We included high- or intermediate-risk patients from two institutions, with 2009 FIGO stage IB–IIA, who underwent primary RH and pelvic lymphadenectomy between January 2007 and June 2020, and had completed adjuvant CCRT. Survival outcomes were compared between patients who received additional chemotherapy (study group) and those who did not (control group). Results A total of 198 patients were included in this analysis. The study (n = 61) and control groups (n = 137) had similar patient age, histologic cancer type, 2009 FIGO stage, and tumor size. However, minimally invasive surgery was performed less frequently in the study group than in the control group (19.7% vs. 46.0%, P

ObjectiveTumor-promoting inflammation is among the hallmarks of cancer. Prekallikrein is among the acute-phase reactants in the inflammatory response; moreover, neutrophils release nuclear contents into the extracellular space to create neutrophil extracellular traps (NET). We aimed to investigate the diagnostic and prognostic utilities of circulating plasma NET markers and prekallikrein for high-grade serous ovarian cancer (HGSOC).MethodsCirculating levels of three NET markers (histone-DNA complex, cell-free DNA, and neutrophil elastase) and prekallikrein were measured in 75 patients with HGSOC and 23 healthy controls. We used an area under the receiver operating characteristic curve (AUC) analysis to investigate their diagnostic and prognostic utilities for HGSOC.ResultsCompared with healthy controls, patients with HGSOC showed significantly higher levels of the three NET markers and prekallikrein. Patients with advanced-stage HGSOC showed significantly higher levels of the cell-free DNA (87.4 vs. 79.5 ng/ml; P = 0.013), compared with those with early-stage HGSOC. Further, the levels of histone-DNA complex, neutrophil elastase, and prekallikrein did not significantly differ according to the cancer stage. All markers showed significant diagnostic utility. Notably, a logistic regression-based model that comprised all four markers showed the strongest diagnostic power (AUC, 0.966; 95% confidence interval [CI], 0.933−1.000). Specifically, neutrophil elastase was identified as an independent poor prognostic factor for overall survival (adjusted hazard ratio [aHR], 10.17; 95% CI, 1.09−94.97; P = 0.042) and progression-free survival (aHR, 14.47; 95% CI, 1.52−137.35; P = 0.020) in patients with HGSOC.ConclusionsThe levels of the three NET markers and prekallikrein might be novel diagnostic and prognostic markers for HGSOC.

Abstract Background Preventing Loss of Independence through Exercise (PLIÉ) is an integrative group movement program developed for adults with mild-to-moderate dementia attending day programs. However, many older adults with dementia ultimately require assistance with their activities of daily living and become residents in nursing homes or other long-term care facilities with their complex comorbidities and unique needs. We conducted a post-implementation evaluation of PLIÉ at a San Francisco Veterans Affairs (VA) nursing home to assess reach and effectiveness among residents, staff, and family members who participated in ≥ 1 PLIÉ class from 9/2018 to 6/2019. Methods Post-implementation number of classes offered and mean attendance; anonymous satisfaction surveys (5-point Likert scales); qualitative content analysis of open-ended survey responses and clinical progress notes. Results Forty-five PLIÉ classes were offered over 9 months. Residents attended an average of 13 ± 12 classes with an average class size of 14 residents, 4 staff members, and 2 family members. Most survey respondents rated the program overall as “very good” or “excellent” (100 % residents, n = 15; 87 % staff, n = 14; 100 % family members, n = 8). Respondents reported improvements in themselves and/or others in four domains: (1) physical, (2) psychological, (3) social, and (4) cognitive. Physical improvements among veterans included mobility, strength, and energy. Psychological improvements included feelings of happiness/well-being, enjoyment, and self-empowerment. Social improvements included connection, social skills, and social support. Cognitive improvements included engagement, communication ability, and focus/attention. Responses were similar among resident, staff, and family member surveys and clinical progress notes. Participants frequently reported improvements in multiple domains (e.g., “The veterans are more alert and engaged, many are smiling and laughing.”). Negative comments were primarily related to logistics, suggesting that the class occur more frequently. Conclusions PLIÉ was successfully implemented in a VA nursing home with high attendance and satisfaction among residents, staff, and family members. Participants reported clinically meaningful physical, psychological, social, and cognitive benefits. Other long-term care facilities could potentially benefit from implementing PLIÉ to increase quality of life in residents with dementia.

Objective: This study aimed to identify the impact of care and change in the consultation process given by a gynecologic hospitalist on patient waiting time in the emergency department (ED). Materials and methods: This is a pre-post study that compared patients’ length of stay at the ED ten months before and after intervention by the gynecologic hospitalist in 2018. The consultation process changed from ED staff contacting the gynecologic resident (pre-intervention group) to directly contacting the gynecologic hospitalist (post-intervention group). Times elapsed from gynecologic consultation to final disposition, from gynecologic consultation to discharge, and from arrival at ED to discharge were compared between the two groups. Results: Among 945 referrals at the ED during the study period, the number of daytime weekday gynecologic consultations were 68 and 187 cases in the pre-intervention and post-intervention groups, respectively. The time elapsed from gynecologic consultation to the final disposition, the time elapsed from gynecologic consultation to discharge and the time elapsed from arrival at ED to discharge were shorter in the post-intervention group than in the pre-intervention group (median values, 98 vs. 167.5 min, 205 vs. 311.5 min, and 419 vs. 497 min; P

Abstract Cognitive impairment is an important predictor of disability in schizophrenia. Dopamine neurotransmission in cortical brain regions has been suggested to be of importance for higher-order cognitive processes. The aim of this study was to examine the relationship between extrastriatal dopamine D2-R availability and cognitive function, using positron emission tomography and the high-affinity D2-R radioligand [11C]FLB 457, in an antipsychotic-naive sample of 18 first-episode psychosis patients and 16 control subjects. We observed no significant associations between D2-R binding in the dorsolateral prefrontal cortex or hippocampus (β = 0.013–0.074, partial r = −0.037–0.273, p = 0.131–0.841). Instead, using Bayesian statistics, we found moderate support for the null hypothesis of no relationship (BFH0:H1 = 3.3–8.2). Theoretically, our findings may suggest a lack of detrimental effects of D2-R antagonist drugs on cognition in schizophrenia patients, in line with clinical observations.

Introduction: Social dysfunction is a key feature of psychotic disorders such as schizophrenia linked to disability. Less is known about social functioning in the early stages of the disorder and if there is an association to psychotic symptoms. Aims: Investigate if antipsychotic drug-naïve or briefly medicated individuals with first-episode psychosis (FEP), have impaired facial affect recognition (FAR) compared to control participants and if psychotic symptoms are associated with the FAR ability. Method: Individuals with FEP (n = 67) and control participants (n = 51) performed a computer-aided FAR task on basic emotions. Psychotic symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS). Group performances were compared using age and gender as covariates. The associations between FAR and performance on the subscales of PANSS were analyzed. Results: Compared to control participants, individuals with FEP were impaired in general FAR (Beta = -2.04 [95 % conf: -3.75/-1.62], p < 0.001) and FAR of negative emotions (Beta = -1.74 [95 % conf: -3.08/-1.22], p < 0.001), driven by difficulties in recognition of anger and disgust. In both groups, there was a pattern of mistaking negative emotions for other negative emotions. There were no significant group differences in FAR of happiness. No significant associations between FAR and psychotic symptoms were observed. Discussion: The results indicate that FAR, an underlying mechanism of social functioning is impaired early in the course of psychotic disorders. Current findings do not support the hypothesis that misinterpretation of facial expressions in individuals with FEP underlies or contributes to symptoms of psychosis.

The scholarship and practice of responsibly navigating the disruptive possibilities of new technologies has yet to fully consider Indigenous worldviews. We draw on Indigenous-led research in northern Australia’s Kakadu National Park to reflect on research practices for responsibly navigating the introduction of aerial drones as a tool for local Indigenous co-managers to monitor and manage this World Heritage Area. We co-developed protocols to guide Indigenous-led innovation – empowering Indigenous governance, developing ethical and trusted research relationships, and enabling on-going Indigenous-led technological innovation. The protocols were applied to negotiate and navigate the use of drone technology at Jarrangbarnmi, an important biocultural landscape in country owned by Jawoyn people in northern Australia. These protocols provide a way for Indigenous cultural responsibilities for knowledge sharing and stewardship of country to guide and authorise the co-design and application of technological innovations, which are increasingly being used to produce new knowledge to adaptively co-manage Indigenous people’s lands and seas.

Abstract Biodiversity loss in European agricultural landscapes is progressing rapidly despite a growing number of conservation efforts. One of the reasons for this is that farmers do not have enough decision‐making power and do not receive adequate advice to tailor conservation measures to local conditions and regional biodiversity targets. In this paper, we therefore address the potential and practical implementation of co‐designing conservation measures through close collaboration between farmers and other stakeholders (e.g. other practitioners, conservation experts, agricultural advisors, scientists and policymakers). Based on interviews with four researchers from ongoing European co‐design projects, one national and one European farmers’ organizations, we discuss the challenges and provide recommendations for co‐design in the context of biodiversity conservation in agricultural landscapes. Our aim is to reach scientists, practitioners and local decision makers working on innovative and locally adapted conservation efforts.

The poor prognosis of ovarian cancer patients mainly results from a lack of early diagnosis approaches and a high rate of relapse. Only a very modest improvement has been made in ovarian cancer patient survival with traditional treatments. More targeted therapies precisely matching each patient are strongly needed. The aberrant activation of Wnt/β-catenin signaling pathway plays a fundamental role in cancer development and progression in various types of cancer including ovarian cancer. Recent insight into this pathway has revealed the potential of targeting Wnt/β-catenin in ovarian cancer treatment. This study aims to investigate the effect of CWP232291, a small molecular Wnt/β-catenin inhibitor on ovarian cancer progression. Various in vitro, in vivo and ex vivo models are established for CWP232291 testing. Results show that CWP232291 could significantly attenuate ovarian cancer growth through inhibition of β-catenin. Noticeably, CWP232291 could also s suppress the growth of cisplatin-resistant cell lines and ovarian cancer patient-derived organoids. Overall, this study has firstly demonstrated the anti-tumor effect of CWP232291 in ovarian cancer and proposed Wnt/β-catenin pathway inhibition as a novel therapeutic strategy against ovarian cancer.

Abstract Background To determine if extended chemotherapy improves survival outcomes in patients with platinum-sensitive relapsed epithelial ovarian cancer (EOC) who have residual disease after six cycles of second-line chemotherapy. Methods In this study, 135 EOC patients who experienced platinum-sensitive recurrence after primary treatment between 2008 and 2018, and had a residual tumor ≥0.5 cm (detected on CT scans) after completing six cycles of second-line, platinum-based chemotherapy, were retrospectively reviewed. Based on the number of main therapy cycles (second-line chemotherapy), we divided patients into an extended group (>6 cycles, n = 52) or a standard group (6 cycles, n = 83) and compared patient characteristics and survival outcomes between these groups. Results The extended group had a shorter platinum-free interval after primary treatment than the standard group (median, 11.0 vs. 13.1 months; P = 0.018). Secondary debulking surgery was less frequently performed in the standard group (1.9% vs. 19.3%; P = 0.003). After six chemotherapy cycles, the extended and standard groups showed similar serum CA-125 levels (P = 0.122) and residual tumor sizes (P = 0.232). There was no difference in overall survival (OS) between the groups (P = 0.382), although the extended group had significantly worse progression-free survival (PFS) than the standard group (median, 13.9 vs. 15.1 months; P = 0.012). Multivariate analyses revealed that platinum-free interval was an independent prognostic factor for PFS and OS, but extended chemotherapy was not (PFS: HR, 1.25; 95% CI, 0.84–1.85; P = 0.279; and OS: HR, 1.36; 95% CI, 0.72–2.56; P = 0.342). We observed consistent results in the subset of patients who did not undergo secondary debulking surgery. Conclusions More than six cycles of platinum-based chemotherapy might not improve survival outcomes in patients with platinum-sensitive recurrent EOC who had a residual tumor ≥0.5 cm after six cycles of second-line chemotherapy.

COVID-19 is a highly contagious disease that killed hundreds of thousands of people and crippled the tourism industry. Despite potential death, many people resumed life as if there was no pandemic. The obscure nature of diseases and overly optimistic beliefs about personal health fostered a unique COVID-19 cavalier phenomenon. These people professed, “It’s just like the flu.” Many engaged in passive (e.g., ignoring mask policies) and active (e.g., COVID parties) behaviors that risked exposure, believing it will generate safe immunity. The COVID-19 cavalier believe they are invulnerable to major adverse complications and communal exposure results in immunity. Identifying and understanding caviler individuals will help control the spread of diseases and reopen society for tourism. The design and validation of the 9-item COVID-19 cavalier scale (CCS) provided a tool for researchers to study these individuals. The economical measure demonstrated discriminant validity with practical public health traveling implications.

Abstract Background Primary debulking surgery (PDS) and adjuvant chemotherapy is the standard treatment for advanced ovarian, fallopian or primary peritoneal cancer. However, neoadjuvant chemotherapy (NAC) followed by interval debulking surgery (IDS) has been introduced as an alternative, showing similar efficacy and decreased postoperative complications compared with PDS. Although there is still no evidence for whether three or four cycles of NAC used clinically could be adequate, reducing one cycle of NAC is expected to remove more visible tumours and thereby improve prognosis. Thus, we proposed with this study to evaluate the efficacy and safety of reducing one cycle of NAC for advanced ovarian, fallopian or primary peritoneal cancer. Methods This study is a prospective, multi-centre, open-label, randomized phase III trial. A total of 298 patients with advanced ovarian, fallopian or primary peritoneal cancer will be recruited and randomly assigned to either three (control group) or two cycles of NAC (experimental group). After the NAC, we will conduct IDS with maximal cytoreduction and then administer the remaining three or four cycles for a total of six cycles of adjuvant chemotherapy. The primary end point is progression-free survival, and the secondary end points are time to tumour progression, overall survival, tumour response after NAC, IDS and adjuvant chemotherapy, radiologic investigation after IDS, tumour response by positron emission tomography-computed tomography after NAC, quality of life, adverse events, success rate of optimal cytoreduction, surgical complexity, postoperative complications and safety of IDS. We will assess these factors at screening, at every cycle of chemotherapy, at IDS, after the completion of chemotherapy, every 3 months for the first 2 years after the planned treatment and every 6 months thereafter for 3 years. Discussion We hypothesize that reducing one cycle of NAC will contribute to more resection of visible tumours despite 10% reduction of optimal cytoreduction, which could improve survival. Moreover, two cycles of NAC may increase postoperative complications by 5% compared with three cycles, which may be acceptable. Trial registration This study has been prospectively registered at ClinicalTrials.gov on Oct. 2nd, 2018 (NCT03693248, URL: https://clinicaltrials.gov/ct2/show/NCT03693248 ).

ObjectiveTo investigate the prognostic significance of programmed cell death ligand-1 (PD-L1) in ovarian cancer.MethodsPubMed, Embase, and Cochrane Library databases were searched to identify studies that examined the prognostic significance of immunohistochemically assessed PD-L1 expression in histologically confirmed ovarian cancer. Eleven studies on PD-L1 expression involving 1,296 patients with ovarian cancer were included in this meta-analysis. Pooled hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) were analyzed. Relationship between PD-L1 expression, and overall survival (OS) or progression-free survival (PFS) among patients with ovarian cancer was assessed. Subgroup analysis was performed based on the race, histologic type, and tumor International Federation of Gynecology and Obstetrics stage to evaluate the source of heterogeneity. Begg's Funnel plot and Egger's linear test were used to evaluate publication bias. Random-effects model was implemented when significant between-study heterogeneity (I2>50%) was observed.ResultsWe found no correlation between PD-L1 expression, and OS (HR, 1.13; 95% CI, 0.95–1.36; I2=78%) or PFS (HR, 1.07; 95% CI, 0.88–1.30; I2=75%) in ovarian cancer. Subgroup analyses showed that higher PD-L1 expression was associated with poor OS in non-Asian patients with ovarian cancer (HR, 1.26; 95% CI, 1.07–1.481; I2=59%). We found that upregulated PD-L1 expression to be a positive predictor for OS in serous ovarian cancer (HR, 0.98; 95% CI, 0.76–1.26; I2=74%) and a negative predictor for OS in non-serous ovarian cancer (HR, 1.29; 95% CI, 1.03–1.61; I2=64%) Furthermore, high PD-L1 expression was found to be a negative predictor for PFS of patients with non-serous ovarian cancer (HR, 1.12; 95% CI, 0.96–1.29; I2=37%).ConclusionOur meta-analysis suggests that PD-L1 expression is not associated with patient risk for ovarian cancer.

The COVID-19 pandemic uprooted economies, infected millions, and altered behaviors. Yet, the invisible nature of the disease, paralleled symptoms to the common flu, and misinformation generated COVID-19 disbelief. Many believed COVID-19 was a hoax. Many believed case numbers were fabricated. Others claimed it was a ruse for sociopolitical reasons. The construction of the 8-item COVID-19 Disbelief Scale (CDS) measures the false belief COVID-19 was not real and life-threatening. The CDS demonstrated discriminant validity and robust reliability across two studies. Predictive analysis evinced COVID-19 disbelievers feared COVID-19 less and had lower intent to get vaccinated. In the U.S., certain religious organizations spread misinformation. Religiosity associated with greater COVID-19 disbelief. Among disbelievers, conditional indirect effects of religiosity associated with greater COVID-19 fear and higher intent to get vaccinated. The moderated mediation model validated utility of the CDS as a concise instrument to study variable relationships.

Binary expression systems like the LexA-LexAop system provide a powerful experimental tool kit to study gene and tissue function in developmental biology, neurobiology, and physiology. However, the number of well-defined LexA enhancer trap insertions remains limited. In this study, we present the molecular characterization and initial tissue expression analysis of nearly 100 novel StanEx LexA enhancer traps, derived from the StanEx1 index line. This includes 76 insertions into novel, distinct gene loci not previously associated with enhancer traps or targeted LexA constructs. Additionally, our studies revealed evidence for selective transposase-dependent replacement of a previously-undetected KP element on chromosome III within the StanEx1 genetic background during hybrid dysgenesis, suggesting a molecular basis for the over-representation of LexA insertions at the NK7.1 locus in our screen. Production and characterization of novel fly lines were performed by students and teachers in experiment-based genetics classes within a geographically diverse network of public and independent high schools. Thus, unique partnerships between secondary schools and university-based programs have produced and characterized novel genetic and molecular resources in Drosophila for open-source distribution, and provide paradigms for development of science education through experience-based pedagogy.

Abstract Objective To evaluate impact of germline BRCA mutational status on prognosis in patients with advanced ovarian cancer. Methods A total of 128 patients diagnosed with FIGO stage III-IV high-grade serous ovarian cancer (HGSOC) between 2008 and 2017 and underwent BRCA1/2 gene testing at the time of or within two years from cancer diagnosis were included in this study. We compared patients’ clinicopathological characteristics and survival outcomes after primary treatment according to germline BRCA mutational status. Treatment-related factors that might affect patients’ survival outcome were also investigated. Results Germline BRCA1/2 mutations were observed in 51 women (39.8%). There were no differences in age and serum CA-125 levels at the time of HGSOC diagnosis, use of neoadjuvant chemotherapy (NAC), extent of debulking surgery, and overall survival (OS) between the BRCA mutation and wild-type BRCA groups. In contrast, the BRCA mutation group displayed longer progression-free survival (PFS) (median, 22.9 vs. 16.9 months, P = 0.001). Multivariate analyses identified germline BRCA1/2 mutation as an independent favorable prognostic factor for PFS (adjusted HR, 0.502; 95% CI, 0.318–0.795; P = 0.003). In the wild-type BRCA group, patients who received NAC as the primary treatment had shorter PFS compared to those who received primary debulking surgery (PDS) (median, 14.2 vs. 16.9 months, P = 0.003). However, in the BRCA mutation group, PFS did not differ between the NAC and PDS groups (P = 0.082). Conclusions In advanced-stage HGSOC, patients with germline BRCA1/2 mutations have better prognosis with longer PFS than those lacking BRCA mutations. Prognosis after NAC was different according to the BRCA mutational status.

Abstract Background The purpose of this study was to investigate the role of malignant ascites tumor microenvironment in ovarian cancer progression and chemoresistance. Methods A total of 45 patients with ovarian cancer and three benign ascites were collected at the time of clinical intervention. Ascites cholesterol levels were quantitated using cholesterol quantitation kit and recurrence free survival (RFS) of ovarian cancer patients were collected. The sensitivity of ovarian cancer cells to cisplatin (CDDP) and paclitaxel (PAC) were assessed by viability assay, flow cytometry and protein expression. Receiver operating characteristics (ROC) curve and Youden index analysis were applied to calculate the optimal cut-off values for ascites cholesterol. Kaplan-Meier curve were applied to compare RFS between high and low ascites cholesterol levels in ovarian cancer patients. Results Here we show that cholesterol is elevated in malignant ascites and modulates the sensitivity of ovarian cancer cells to CDDP and PAC by upregulating the expression of drug efflux pump proteins, ABCG2 and MDR1, together with upregulation of LXRɑ/β, the cholesterol receptor. Transfection of LXRɑ/β siRNA inhibited cholesterol-induced chemoresistance and upregulation of MDR1. In addition, the cholesterol level in malignant ascites was negatively correlated with number of CDDP-induced apoptotic cell death, but not with that of PAC-induced apoptotic cell death. Cholesterol depletion by methyl beta cyclodextrin (MβCD) inhibited malignant ascites-induced chemoresistance to CDDP and upregulation of MDR1 and LXRɑ/β. For patients with ovarian cancer, high cholesterol level in malignant ascites correlated with short RFS. Conclusions High cholesterol in malignant ascites contributes to poor prognosis in ovarian cancer patients, partly by contributing to multidrug resistance through upregulation of MDR1 via activation of LXRɑ/β.

# Background Post-performance verbal and visual feedback based on data collected via lab-based instruments have been shown to improve landing patterns related to non-contact ACL injury. Biomechanical methods are often complex, difficult to transport and utilize in field settings, and costly, which limits their use for injury prevention. Developing systems that can readily provide feedback outside of the lab setting may support large scale use of feedback training for ACL injury prevention. # Purpose/Hypothesis The purpose of this study was to investigate the effectiveness of a single training session using a custom portable feedback training system that provides performance cues to promote changes in impact kinetics and lower extremity position during landing in female athletes. # Study Design Repeated measures # Methods One hundred fifty female athletes (ages 13-18 years old) landed from a 50 cm platform with and without feedback related to vertical ground reaction force (vGRF), vGRF symmetry and lower extremity position. Feedback was provided via a portable, low-cost system that included two custom-built force plates interfaced with a digital camera. Each athlete performed six pre-test trials followed by two blocks of six trials where they received visual feedback from the training system and individualized verbal cues from an investigator. Following training blocks, athletes completed six post-test trials without feedback and then six dual-task trials where a ball was randomly thrown to the performer during the landing (transfer task). vGRF and knee to ankle (K:A) separation ratio were measured and the average responses were reported for each trial block. # Results Differences in vGRF between baseline, post-test and transfer task trial blocks were observed (F(2,298)=181.68, p < .0001). Mean (SD) peak vGRF (body weight) were 4.43 (0.90), 3.28 (0.61), and 3.80 (0.92), respectively. Differences in K:A ratio between baseline, post-test and transfer task trial blocks were shown (F(2,298)=68.47, p < .0001). Mean (SD) K:A ratio were 0.87 (0.21), 0.98 (0.19), and 0.92 (0.19), respectively. # Conclusion A portable feedback system may be effective in reducing peak vGRFs and promoting a more desirable K:A ratio during landing and transfer task landing in adolescent female athletes. # Level of Evidence 3b

The killing of day-old chicks is controversially discussed in poultry keeping, science, politics, and society. The present survey data contributes to understand consumers´ attitudes towards ethical issues in chicken production, especially the killing practice and dual purpose chickens as alternative to avoid such killing. Information on the various topics is provided: Consumer purchase pattern of eggs and chicken meat, perception of animal welfare and protection issues, knowledge and perception of killing day-old chicks, attitudes towards dual purpose chickens as an alternative to killing day-old chicks, and socio-demographic data. The data set contains standardized responds of 1000 telephone interviews. These interviews were conducted with German consumers in spring 2016. The survey data were in part analysed with cluster analysis to categorize consumers according to their purchasing criteria for dual chicken products, and assessing which socio-economic variables best described each of the consumer categories. The survey raw data, a file with the questionnaire and the codes, the analysed data, and additional files for understanding the cluster analysis are hosted in the public repository Open Research Data https://www.doi.org/10.4228/ZALF.DK.106.

Abstract Background Somatic amplifications of the LYL1 gene are relatively common occurrences in patients who develop uterine corpus endometrial carcinoma (UCEC) as opposed to other cancers. This study was undertaken to determine whether such genetic alterations affect survival outcomes of UCEC. Methods In 370 patients with UCEC, we analysed clinicopathologic characteristics and corresponding genomic data from The Cancer Genome Atlas database. Patients were stratified according to LYL1 gene status, grouped as amplification or non-amplification. Heightened levels of cancer-related genes expressed in concert with LYL1 amplification were similarly investigated through differentially expressed gene and gene set enrichment analyses. Factors associated with survival outcomes were also identified. Results Somatic LYL1 gene amplification was observed in 22 patients (5.9%) with UCEC. Patients displaying amplification (vs. non-amplification) were significantly older at the time of diagnosis and more often were marked by non-endometrioid, high-grade, or advanced disease. In survival analysis, the amplification subset showed poorer progression-free survival (PFS) and overall survival (OS) rates (3-year PFS: 34.4% vs. 79.9%, P = 0.031; 5-year OS: 25.1% vs. 84.9%, P = 0.014). However, multivariate analyses adjusted for tumor histologic type, grade, and stage did not confirm LYL1 gene amplification as an independent prognostic factor for either PFS or OS. Nevertheless, MAPK, WNT, and cell cycle pathways were significantly enriched by LYL1 gene amplification (P

Abstract The lymphatic system plays a key role in tissue fluid homeostasis, immune cell trafficking, and fat absorption. We previously reported a bacterial artificial chromosome (BAC)-based lymphatic reporter mouse, where EGFP is expressed under the regulation of the Prox1 promoter. This reporter line has been widely used to conveniently visualize lymphatic vessels and other Prox1-expressing tissues such as Schlemm’s canal. However, mice have a number of experimental limitations due to small body size. By comparison, laboratory rats are larger in size and more closely model the metabolic, physiological, and surgical aspects of humans. Here, we report development of a novel lymphatic reporter rat using the mouse Prox1-EGFP BAC. Despite the species mismatch, the mouse Prox1-EGFP BAC enabled a reliable expression of EGFP in Prox1-expressing cells of the transgenic rats and allowed a convenient visualization of all lymphatic vessels, including those in the central nervous system, and Schlemm’s canal. To demonstrate the utility of this new reporter rat, we studied the contractile properties and valvular functions of mesenteric lymphatics, developed a surgical model for vascularized lymph node transplantation, and confirmed Prox1 expression in venous valves. Together, Prox1-EGFP rat model will contribute to the advancement of lymphatic research as a valuable experimental resource.

PURPOSE. To evaluate the prognostic value of metabolic parameters derived from serial 18F fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) in patients with advanced epithelial ovarian cancer (EOC). METHODS. Thirteen patients with advanced EOC who received surgical staging and adjuvant platinum-based combination chemotherapy were prospectively enrolled. 18F–FDG PET/CT was performed before and after the surgical staging, and after third cycle of chemotherapy. Tumor glucose metabolism at baseline and its change after operation and third cycle of chemotherapy such as changes of maximum standardized uptake values (ΔSUVmax) via 18F–FDG PET/CT were measured, and assessed regarding their ability to predict recurrence. RESULTS. Median duration of progression-free survival (PFS) was 25 months (range, 13–34), and although optimal debulking was performed in 10 patients, 5 (38.5%) patients experienced recurrence. Univariate analyses showed significant associations between recurrence and low ΔSUVmax after surgical staging, and low SUVmax change after third cycle of chemotherapy. Multivariate analysis identified low ΔSUVmax after third cycle of chemotherapy as an independent risk factor for recurrence (P = .047, hazard ratio (HR) 16.375, 95% CI 1.041–257.536). Kaplan–Meier survival curves showed that PFS significantly differed in groups categorized based on ΔSUVmax after chemotherapy (P = .001, log-rank test). CONCLUSIONS. 18F–FDG PET/CT allows for prediction of treatment response by the level of FDG uptake in terms of SUV at baseline and after chemotherapy. The metabolic response measured as ΔSUVmax after third cycle of chemotherapy appears to be promising predictor of recurrence in patients with advanced EOC.

PURPOSE: To investigate the prognostic value of preoperative intratumoral 18F-FDG uptake heterogeneity (IFH) derived from positron emission tomography (PET)/computed tomography (CT) in patients with endometrioid endometrial cancer. METHODS: We retrospectively evaluated clinicopathological data from patients with pathologically proven endometrioid endometrial cancer who had undergone 18F-FDG PET/CT scans before surgery. Patients were divided into two groups according to their IFH. The main outcome measure was disease-free survival (DFS). RESULTS: Between January 2010 and January 2015, data from 72 patients were available for analysis. The median duration of DFS was 23 months (range, 6 to 57 months), and 4 (5.6%) patients experienced recurrence. There were significant differences in tumor size, IFH, and DFS between patients with and without recurrence. In regression analysis, high IFH value [P = .007, hazard ratio (HR) 2.545, 95% confidence interval (CI) 1.468-8.674] was the only independent risk factor for recurrence. The Kaplan-Meier survival graphs showed that DFS significantly differed in groups categorized based on IFH (P < .001, log-rank test). CONCLUSIONS: Preoperative IFH measured by 18F-FDG PET/CT was associated with recurrence of endometrioid endometrial cancer. The finding supports evidence that FDG-based heterogeneity can be a novel and useful predictor of endometrioid endometrial cancer recurrence.

This study aims to analyze the published literatures on the effect of less radical fertility-preserving procedures, such as conization or simple trachelectomy, on oncological outcomes in IA1 cervical cancer patients with lymphovascular space invasion (LVSI) through a systematic-review.The EMBASE and MEDLINE databases and Cochrane Library were searched for published studies reporting the oncological outcomes of conization/simple trachelectomy in these patients, through April 2017. The endpoints were recurrence and mortality rates. Data were presented as per the Meta-analysis Of Observational Studies in Epidemiology checklist. Practice guidelines were generated via the Grading of Recommendation, Assessment, Development and Evaluation system.From 6,755 records, 94 full-texts articles were reviewed for eligibility, and five studies were included in this systematic review. All included studies were nonrandomized studies: two case-control studies comparing conization (n = 14) with hysterectomy (n = 24), and the other three were interrupted time series including conization (n = 20) and simple vaginal trachelectomy (n = 59). During the median follow-up duration of 43 months, no recurrence was reported in both conization and simple trachelectomy groups in IA1 patients with LVSI. From three studies reporting the fertility outcomes, the rates of pregnancy, live birth, preterm delivery, and second-trimester miscarriage were 73% (35/48), 64% (32/50), 10% (5/48), and 6% (3/48), respectively.Results suggest that simple trachelectomy or conization could be performed for IA1 cervical cancer patients with LVSI who want to preserve fertility, although these results are only based on a small number of nonrandomized studies (recommendation grade 2 = weak; evidence level D = very low). Further randomized trials with long-term study period are needed to address this issue.

Understanding how genes impact the brain's functional activation for learning and cognition during development remains limited. We asked whether a common genetic variant in the BDNF gene (the Val66Met polymorphism) modulates neural activation in the young brain during a critical period for the emergence and maturation of the neural circuitry for reading. In animal models, the bdnf variation has been shown to be associated with the structure and function of the developing brain and in humans it has been associated with multiple aspects of cognition, particularly memory, which are relevant for the development of skilled reading. Yet, little is known about the impact of the Val66Met polymorphism on functional brain activation in development, either in animal models or in humans. Here, we examined whether the BDNF Val66Met polymorphism (dbSNP rs6265) is associated with children's (age 6-10) neural activation patterns during a reading task (n = 81) using functional magnetic resonance imaging (fMRI), genotyping, and standardized behavioral assessments of cognitive and reading development. Children homozygous for the Val allele at the SNP rs6265 of the BDNF gene outperformed Met allele carriers on reading comprehension and phonological memory, tasks that have a strong memory component. Consistent with these behavioral findings, Met allele carriers showed greater activation in reading-related brain regions including the fusiform gyrus, the left inferior frontal gyrus and left superior temporal gyrus as well as greater activation in the hippocampus during a word and pseudoword reading task. Increased engagement of memory and spoken language regions for Met allele carriers relative to Val/Val homozygotes during reading suggests that Met carriers have to exert greater effort required to retrieve phonological codes.

We evaluated the effect of red ginseng on toxicity, health-related quality of life (HRQL) and survival after adjuvant chemotherapy in patients with epithelial ovarian cancer (EOC). A total of 30 patients with EOC were randomly assigned to placebo (n = 15) and red ginseng groups (n = 15). All patients took placebo or red ginseng (3000 mg/day) for three months. Then, we compared changes of genotoxicity, HRQL and survival between the two groups. As a result, red ginseng reduced micronuclei yield in comparison with placebo despite no difference of binucleated cells index. Although red ginseng increased serum levels of alanine aminotransferase and aspartate aminotransferase significantly, they were within the normal value. Moreover, there were no differences in adverse events between placebo and red ginseng groups. In terms of HRQL, red ginseng was associated with improved emotional functioning and decreased symptoms of fatigue, nausea and vomiting, and dyspnea, reduced anxiety and interference affecting life and improved daytime somnolence. However, there was no effect of red ginseng on prognosis of EOC. Conclusively, red ginseng may be safe and effective to reduce genotoxicity and improve HRQL despite no benefit of survival in patients with EOC who received chemotherapy.

Open distance learning (ODL) has long been an important option for formal and non-formal education (NFE) in most developed and developing countries, but less so in post-conflict countries, including Cambodia. However, in Cambodia there is now greater awareness that ODL can complement traditional face-to-face educational approaches, particularly as there is a shortage of teachers in the country. Thus, understanding how ODL can achieve learning and other objectives has important implications for both formal education and NFE. If it can be found to be effective, ODL has the potential of reaching a large number of people at comparatively lower average costs. This paper reports on a project where the same content was taught to farmers in Cambodia via traditional face-to-face and via ODL and compares outcomes between the different training methods. Exploring the extent to which farmers had adopted new farm practices taught in the course, our results indicate that the outcomes did not vary considerably between those trained using the different approaches.

Objective: The International Federation of Gynecology and Obstetrics committee modified the endometrial cancer (EC) staging system based on the histopathological feature and molecular profile. The aim is to evaluate the clinical implications of the new 2023 system compared with the previous 2009 system. Methods: We retrospectively identified 161 patients with EC who underwent primary surgical treatment between 2014 and 2018 at Seoul National University Hospital. The droplet-digital polymerase chain reaction for POLE mutations and immunohistochemistry for MLH1, PMS2, MS2, MSH6, and p53 were performed using tissues from formalin-fixed, paraffin-embedded blocks. All patients were categorized according to the 2009 and 2023 staging systems. Results: The median follow-up period was 62.9 months (range, 0.3-110.9), and the median age was 57.2 years old (range, 28.0-85.9). The 5-year progression-free survival (PFS) for the 2023 system with molecular classification was 80.3% for stage I, 75.2% for stage II, 61.2% for stage III, and 22.2% for stage IV (p<0.001). Patients with the 2009 stage I and II disease were restaged using the 2023 system. In contrast, patients with stage III and IV disease were fixed in the 2009 and 2023 systems. Molecular classification downstaged 10 patients (71.4%) to IAmPOLEmut and upstaged 6 patients (37.5%) to IICmp53abn. The 2023 system with molecular classification was associated with PFS and overall survival (p<0.001 and p=0.038). Conclusion: The 2023 staging system for EC subdivided stages I and II compared to the 2009 system. The 2023 system with molecular classification is a good predictor of survival.

Background/Aim: Over the past several decades, new anti-cancer drugs have been developed for the treatment of epithelial ovarian cancer. The development of drugs has led to changes in improving the prognosis of ovarian cancer patients. One of these drugs, bevacizumab, is used for advanced or recurrent ovarian cancer. In this study, we aimed to evaluate survival improvement in patients with platinumresistant relapsed epithelial ovarian cancer (PR-ROC) after introduction of bevacizumab in real world experience. Patients and Methods: We retrospectively divided patients with PRROC into two groups: bevacizumab plus chemotherapy (BEVCT group) and chemotherapy alone (CT group). Progressionfree survival (PFS), the primary endpoint, between two groups was compared to evaluate whether survival outcomes were improved. In addition, overall survival (OS) was also compared. Results: A total of 154 patients were included in the study: 57 and 97 patients in the BEV-CT and CT groups, respectively. OS was significantly longer in the BEV-CT group than in the CT group. The use of bevacizumab was identified as a favorable prognostic factor for OS. In a subgroup analysis confined to second-line chemotherapy, PFS and OS were statistically different between groups. More patients in the CT group suffered hematologic adverse events of grade 3 or above than patients in the BEV-CT group. Conclusion: In a real-world clinical setting, introduction of bevacizumab led to improvement of OS in patients with PR-ROC with a tolerable toxicity. [ABSTRACT FROM AUTHOR]
