RESUMO

OBJECTIVE: When the peritoneal cavity cannot serve as the distal shunt terminus, nonperitoneal shunts, typically terminating in the atrium or pleural space, are used. The comparative effectiveness of these two terminus options has not been evaluated. The authors directly compared shunt survival and complication rates for ventriculoatrial (VA) and ventriculopleural (VPl) shunts in a pediatric cohort. METHODS: The Hydrocephalus Clinical Research Network Core Data Project was used to identify children ≤ 18 years of age who underwent either VA or VPl shunt insertion. The primary outcome was time to shunt failure. Secondary outcomes included distal site complications and frequency of shunt failure at 6, 12, and 24 months. RESULTS: The search criteria yielded 416 children from 14 centers with either a VA (n = 318) or VPl (n = 98) shunt, including those converted from ventriculoperitoneal shunts. Children with VA shunts had a lower median age at insertion (6.1 years vs 12.4 years, p < 0.001). Among those children with VA shunts, a hydrocephalus etiology of intraventricular hemorrhage (IVH) secondary to prematurity comprised a higher proportion (47.0% vs 31.2%) and myelomeningocele comprised a lower proportion (17.8% vs 27.3%) (p = 0.024) compared with those with VPl shunts. At 24 months, there was a higher cumulative number of revisions for VA shunts (48.6% vs 38.9%, p = 0.038). When stratified by patient age at shunt insertion, VA shunts in children < 6 years had the lowest shunt survival rate (p < 0.001, log-rank test). After controlling for age and etiology, multivariable analysis did not find that shunt type (VA vs VPl) was predictive of time to shunt failure. No differences were found in the cumulative frequency of complications (VA 6.0% vs VPl 9.2%, p = 0.257), but there was a higher rate of pneumothorax in the VPl cohort (3.1% vs 0%, p = 0.013). CONCLUSIONS: Shunt survival was similar between VA and VPl shunts, although VA shunts are used more often, particularly in younger patients. Children < 6 years with VA shunts appeared to have the shortest shunt survival, which may be a result of the VA group having more cases of IVH secondary to prematurity; however, when age and etiology were included in a multivariable model, shunt location (atrium vs pleural space) was not associated with time to failure. The baseline differences between children treated with a VA versus a VPl shunt likely explain current practice patterns.

RESUMO

BACKGROUND: With the approval of disease-modifying treatments (DMTs) for early Alzheimer's disease (AD), there is an increased need for efficient and non-invasive detection methods for cerebral amyloid-ß (Aß) pathology. Current methods, including positron emission tomography (PET) and cerebrospinal fluid (CSF) analysis, are costly and invasive methods that may limit access to new treatments. Plasma tau phosphorylated at threonine-217 (P-tau217) presents a promising alternative, yet optimal cutoffs for treatment eligibility with DMTs like aducanumab require further investigation. This study evaluates the efficacy of one- and two-cutoff strategies for determining DMT eligibility at the Butler Hospital Memory & Aging Program (MAP). METHODS: In this retrospective, cross-sectional diagnostic cohort study, we first developed P-tau217 cutoffs using site-specific and BioFINDER-2 training data, which were then tested in potential DMT candidates from Butler MAP (total n = 150). ROC analysis was used to calculate the area under the curve (AUC) and accuracy of P-tau217 interpretation strategies, using Aß-PET/CSF testing as the standard of truth. RESULTS: Potential DMT candidates at Butler MAP (n = 50), primarily diagnosed with mild cognitive impairment (n = 29 [58%]) or mild dementia (21 [42%]), were predominantly Aß-positive (38 [76%]), and half (25 [50%]) were subsequently treated with aducanumab. Elevated P-tau217 predicted cerebral Aß positivity in potential DMT candidates (AUC = 0.97 [0.92-1]), with diagnostic accuracy ranging from 0.88 (0.76-0.95, p = 0.028) to 0.96 (0.86-1, p < .001). When using site-specific cutoffs, a subset of DMT candidates (10%) exhibited borderline P-tau217 (between 0.273 and 0.399 pg/mL) that would have potentially required confirmatory testing. CONCLUSIONS: This study, which included participants treated with aducanumab, confirms the utility of one- and two-cutoff strategies for interpreting plasma P-tau217 in assessing DMT eligibility. Using P-tau217 could potentially replace more invasive diagnostic methods, and all aducanumab-treated participants would have been deemed eligible based on P-tau217. However, false positives remain a concern, particularly when applying externally derived cutoffs that exhibited lower specificity which could have led to inappropriate treatment of Aß-negative participants. Future research should focus on prospective validation of P-tau217 cutoffs to enhance their generalizability and inform standardized treatment decision-making across diverse populations.

RESUMO

BACKGROUND: Engaging in clinical research includes confronting challenges about the uncertainty around outcomes and ramifications the results may have on practice. This is pertinent for osteopathy where little is known about the experiences of osteopaths involved in clinical trials. The aim of this study was to explore the lived experience of osteopaths who participated in a randomised controlled trial for infantile colic. The study was informed by a principles-based approach to clinical ethics and their application to practice. DESIGN: Qualitative study using semi-structured interviews and reflexive thematic analysis. SETTING: An international two-arm pragmatic randomised controlled trial (the CUTIES trial) to evaluate the effectiveness of osteopathic care for infantile colic. METHODS: A principles-based approach to clinical ethics and their application to practice for osteopaths asked to make decisions about participating in a clinical trial was used. Osteopaths from the UK and Australia who completed the CUTIES trial training were invited to be interviewed about their experiences, regardless of whether they went on to recruit infants in the trial. Interviewees were asked about their reasons for wanting to participate in the CUTIES trial, why they decided to continue or not to continue in the trial and, for those who completed the trial, their personal experiences as participants in the trial. Data were analysed using reflexive thematic analysis. RESULTS: Nine osteopaths were interviewed. Three themes were identified from the data: Paradigm dilemma - observed clinical outcomes vs scientific evidence for mechanism of effects; trial-related ethical dilemmas; and trial outcome dilemmas. CONCLUSION: Participating in the CUTIES trial required osteopaths to overcome clinical ethical dilemmas for the benefit of patients, the research, and the profession.

RESUMO

BACKGROUND: Calciphylaxis patients historically have experienced diagnostic challenges and high morbidity, however limited data is available examining these characteristics over time. OBJECTIVE: The primary goals were to a) investigate factors associated with diagnostic delay of calciphylaxis and b) assess morbidity outcomes. The secondary goal was to provide updated mortality rates. METHODS: A retrospective review of 302 adult patients diagnosed with calciphylaxis between January 1, 2006 and December 31, 2022 was conducted. Univariate and multivariate statistical analyses were performed. RESULTS: Non-nephrogenic calciphylaxis (p=0.0004) and involvement of the fingers (p=0.0001) were significantly associated with an increased diagnostic delay, whereas involvement of the arms (p=0.01) and genitalia (p=0.022) resulted in fewer days to diagnosis. Almost all patients with genitalia, finger, or toe involvement had nephrogenic disease. The number of complications per patient decreased with time, especially for wound infections (p=0.028), increase in lesion number (p=0.012), and recurrent hospitalizations (p=0.020). Updated 1-year mortality rates were 36.70% and 30.77% for nephrogenic and non-nephrogenic calciphylaxis, respectively. LIMITATIONS: Limitations include the retrospective nature and data from a single institution. CONCLUSION: Diagnostic delay, particularly in non-nephrogenic calciphylaxis, and complications per patient decreased with time, highlighting the importance of continued awareness to expedite diagnosis. Mortality rates have continued to improve in recent years.

RESUMO

Gallbladder cancer (GBC) is one of the commonest biliary malignancies seen in India, Argentina, and Japan. The disease has dismal outcome as it is detected quite late due to nonspecific symptoms and signs. Early detection is the only way to improve the outcome. There have been several advances in basic as well as clinical research in the hepatobiliary and pancreatic diseases in the West and other developed countries but not enough has been done in GBC. Therefore, it is important and the responsibility of the countries with high burden of GBC to find solutions to the many unanswered questions like etiopathogenesis, early diagnosis, treatment, and prognostication. As India being one of the largest hubs for GBC in the world, it is important to know how the country has progressed on GBC. In this review, we will discuss the outcome of the publications from India highlighting the work and the developments taken place in past several decades both in basic and clinical research.

RESUMO

BACKGROUND: During the COVID-19 pandemic, mitigation measures were associated with a reduction in preterm birth rates; while not clearly proven, this observation has sparked significant interest. AIM: To understand the cause of this reduction by exploring the characteristics of preterm birth cohorts. MATERIAL AND METHODS: We performed a retrospective cohort study where we compared women who delivered preterm in three Melbourne maternity hospitals and conceived between November 2019 and February 2020 (mitigation measures-exposed cohort) to women who delivered preterm and conceived between November 2018 and February 2019 (non-exposed cohort). We compared maternal characteristics, pregnancy complications, antenatal interventions, intrapartum care, and indications for delivery. RESULTS: In the exposed cohort, 252/3129 women delivered preterm (8.1%), vs 298/3154 (9.4%) in the non-exposed cohort (odds ratio (OR) 0.84, 95% CI 0.70-1.00, P = 0.051). The baseline characteristic of two cohorts were comparable. Rates of spontaneous preterm labour (sPTL) without preterm pre-labour rupture of membranes (PPROM) were lower in the exposed cohort (13.1% vs 24.2%, OR 0.47, P = 0.001) while PPROM occurred more often (48.0% vs 35.6%, OR 1.67, P = 0.003). With a non-statistically significant prolongation of pregnancy in the cohort exposed to mitigation measures for both sPTL without PPROM (35.4 vs 34.9 weeks, P = 0.703) and PPROM (35.6 vs 34.9 weeks, P = 0.184). The rate of spontaneous labour after PPROM was higher in the exposed cohort compared to the non-exposed cohort (40.1% vs 24.1%, OR 2.09, P < 0.001). CONCLUSION: The reduction in preterm delivery during mitigation measures may have been driven by a reduction in spontaneous labour without PPROM, which seemed to result in more PPROM later in pregnancy.

RESUMO

Background: Bipolar disorder is one of the severe mental disorders that are associated with significant morbidity of the patients. Despite advancements in our understanding about the disorder, it remains a challenging proposition to treat bipolar disorder, largely since the prophylactic treatment of the disorder requires assessment of complex clinical algorithms. The revisions of the classificatory systems have also changed the conceptualization of the disorder. In this background, we conducted a review of the Indian studies conducted on the clinical aspects of bipolar disorder. Methods: A narrative review was conducted with focus on the literature published from India. The databases searched included PubMed, Scopus, and Google Scholar, and articles published over the last 15 years by Indian authors were included for this review. Results: In our review, we could access a substantial volume of research published from India. We could identify studies that catered to most of the relevant themes in bipolar disorder including epidemiology, etiology, comorbidities, stigma, disability, clinical course, cognitive profile, pathways to care, and recovery. Conclusion: The research trajectory was in line with the research conducted elsewhere in the world. However, certain dissimilarities in terms of focus could also be observed. The possible reason behind this deviation could be the difference in clinical need and unique challenges faced in the management and rehabilitation of patients in bipolar disorder in Indian scenario.

RESUMO

Objective: Research study complexity refers to variables that contribute to the difficulty of a clinical trial or study. This includes variables such as intervention type, design, sample, and data management. High complexity often requires more resources, advanced planning, and specialized expertise to execute studies effectively. However, there are limited instruments that scale study complexity across research designs. The purpose of this study was to develop and establish initial psychometric properties of an instrument that scales research study complexity. Methods: Technical and grammatical principles were followed to produce clear, concise items using language familiar to researchers. Items underwent face, content, and cognitive validity testing through quantitative surveys and qualitative interviews. Content validity indices were calculated, and iterative scale revision was performed. The instrument underwent pilot testing using 2 exemplar protocols, asking participants (n = 31) to score 25 items (e.g., study arms, data collection procedures). Results: The instrument (Research Complexity Index) demonstrated face, content, and cognitive validity. Item mean and standard deviation ranged from 1.0 to 2.75 (Protocol 1) and 1.31 to 2.86 (Protocol 2). Corrected item-total correlations ranged from .030 to .618. Eight elements appear to be under correlated to other elements. Cronbach's alpha was 0.586 (Protocol 1) and 0.764 (Protocol 2). Inter-rater reliability was fair (kappa = 0.338). Conclusion: Initial pilot testing demonstrates face, content, and cognitive validity, moderate internal consistency reliability and fair inter-rater reliability. Further refinement of the instrument may increase reliability thus providing a comprehensive method to assess study complexity and related resource quantification (e.g., staffing requirements).

RESUMO

Missing visual elements (MVE) in Kaplan-Meier (KM) curves can misrepresent data, preclude curve reconstruction, and hamper transparency. This study evaluated KM plots of phase III oncology trials. MVE were defined as an incomplete y-axis range or missing number at risk table in a KM curve. Surrogate endpoint KM curves were additionally evaluated for complete interpretability, defined by (1) reporting the number of censored patients and (2) correspondence of the disease assessment interval with the number at risk interval. Among 641 trials enrolling 518 235 patients, 116 trials (18%) had MVE in KM curves. Industry sponsorship, larger trials, and more recently published trials were correlated with lower odds of MVE. Only 3% of trials (15 of 574) published surrogate endpoint KM plots with complete interpretability. Improvements in the quality of KM curves of phase III oncology trials, particularly for surrogate endpoints, are needed for greater interpretability, reproducibility, and transparency in oncology research.

RESUMO

Background: A gap in the literature exists pertaining to a global research nurse/research midwife resources and communication skill set necessary to engage with participants of diverse populations and geographic regions in the community or home-based conduct of decentralized clinical trials. Aims: An embedded mixed methods study was conducted to examine research nurse/research midwife knowledge base, experiences, and communication skill sets pertaining to decentralized trials across global regions engaged in remote research: the USA, Republic of Ireland, United Kingdom, and Australia. Methods: An online survey was deployed across international research nurse/research midwife stakeholder groups, collecting demographics, decentralized trial experience, barriers and facilitators to optimal trial conduct, and the self-perceived communication competence (SPCC) and interpersonal communication competence (IPCC) instruments. Results: 86 research nurses and research midwives completed the survey across all countries: The SPCC and IPCC results indicated increased clinical research experience significantly correlated with increased SPCC score (p < 0.05). Qualitative content analysis revealed five themes: (1) Implications for Role, (2) Safety and Wellbeing, (3) Training and Education, (4) Implications for Participants, and (5) Barriers and Facilitators. Conclusions: Common trends and observations across the global sample can inform decentralized trial resource allocation and policy pertaining to the research nurse/research midwife workforce. This study demonstrates shared cultural norms of research nursing and midwifery across varied regional clinical trial ecosystems.

RESUMO

Gothic literature-a genre brimming with madness, supernaturalism, and psychological terror-offers innumerable case studies potentially representing how psychiatric patients perceive their treatment from healthcare professionals. Charlotte Perkins Gilman's famous 1892 short story "The Yellow Wallpaper" offers a poignant example of this through its fictional narrator, a diarist many interpret to be suffering from postpartum depression. The fiction here does not stray far from reality: Gilman orchestrated her diarist's experience to mirror her own, as both real author and fictional character suffocated from a melancholy only made worse by their physicians' insistence on following the "Rest Cure." While this instruction to cease all work and activity was a prevalent depression treatment at the time, Gilman, through "The Yellow Wallpaper," reveals how the intervention ultimately harmed more than helped because it overlooked her-and, by extension, her fictional diarist's- unique needs and identities. Today, while the ineffective Rest Cure no longer exists, applying observations from "The Yellow Wallpaper" to clinical research calls attention to underrepresentation in treatment development, a costly problem that could be mitigated by mindful incorporation of intersectionality theory into study designs.

RESUMO

Clinical trials (CTs) are essential for medical advancements but face significant challenges, particularly in professional training and role clarity. Principal investigators, clinical research coordinators (CRCs), nurses, clinical trial pharmacists, and monitors are key players. Each faces unique challenges, such as maintaining protocol compliance, managing investigational products, and ensuring data integrity. Clinical trials' complexity and evolving nature demand specialized and ongoing training for these professionals. Addressing these challenges requires clear role delineation, continuous professional development, and supportive workplace environments to improve retention and trial outcomes. Enhanced training programs and a collaborative approach are essential for the successful conduct of clinical trials and the advancement of medical research.

RESUMO

OBJECTIVE: Clinical research is a growing part of the academic clinician's job, and documenting areas of low self-efficacy can inform training initiatives. SAMPLE: 182 US academic veterinary clinicians. METHODS: A survey of academic veterinary clinicians was distributed to 31 US institutions. Self-efficacy was assessed with a modified Clinical Research Appraisal Instrument-12. The relationship between research self-efficacy and completion of formal research training and years of experience was evaluated. RESULTS: Respondents were predominantly junior to midcareer faculty. The lowest reported confidence was in performing advanced statistical analyses (3; 0 to 10). Other low-confidence tasks included designing a qualitative methods study (4; 0 to 10), terminating a collaboration that isn't working (5; 0 to 10), describing a funding agency's review/award process (5; 0 to 10), establishing a timeline for a grant application (5; 0 to 10), establishing collaborator and consultant agreements (5; 0 to 10), and asking staff to leave the project team (5; 0 to 10). Completion of a formal research training program was significantly associated with improved self-efficacy in many tasks. Years of experience was also associated, especially in project management and interpersonal interactions. CLINICAL RELEVANCE: These results highlight the need for targeted training opportunities for academic veterinary clinicians in biostatistical support, qualitative study design methods, and aspects of communication and interpersonal skills that are important for developing and leading effective research teams. Range of confidence suggests that development opportunities in all domains will improve self-efficacy for some clinicians. Future studies should focus on the impact of formal training sessions on various domains of self-efficacy and on targeted mentoring in supporting confidence in more experiential learning domains.

RESUMO

OBJECTIVES: Clinical research professionals must be equipped with adequate training in sound scientific methods and appropriate ethics. In this study, we aimed to assess the current clinical research self-efficacy of researchers at Hamad Medical Corporation (HMC). We also evaluated the effects of training courses on researchers' self-efficacy. METHODS: Utilizing a cross-sectional design, we used the shortened Clinical Research Appraisal Inventory (CRAI-12) through an online survey to assess the current clinical research self-efficacy of 600 researchers at HMC, Doha, Qatar. After conducting descriptive analyses, unpaired t test and ANOVA were used to determine significant mean percentages between variables. Pearson correlation coefficients were also calculated to measure the association among the interval variables. All tests were 2-sided, and significance was defined as P < .05. RESULTS: For all questions, except those related to "funding," most participants scored on the upper half of the scale (>5), reflecting higher self-efficacy for the topics covered in CRAI. Gender differences were significant across all factors, with males reporting higher levels of self-assessed efficacy and in clinical research. Other factors such as higher education degrees and previous (external) clinical research training were also associated with higher self-reported clinical research efficacy. CONCLUSIONS: The findings of this study indicate that researchers at HMC possess high clinical research self-efficacy overall, but lower self-efficacy in securing funding. Gender and education level positively influence self-efficacy across CRAI factors. Notably, clinical research training boosts self-efficacy, especially when obtained outside HMC. In conclusion, healthcare providers are strongly encouraged to engage in effective clinical research training courses, both within and outside of their healthcare institutions, to improve their clinical research efficacy and enhance clinical practice.

RESUMO

Brain-computer interface (BCI) technology is rapidly advancing in medical research and application. As an emerging biomedical engineering technology, it has garnered significant attention in the clinical research of brain disease diagnosis and treatment, neurological rehabilitation, and mental health. However, BCI also raises several challenges and ethical concerns in clinical research. In this article, the authors investigate and discuss three aspects of BCI in medicine and healthcare: the state of ethical governance, multidimensional ethical challenges pertaining to BCI in clinical research, and suggestive concerns for ethical review. Despite the great potentials of frontier BCI research and development in the field of medical care, the ethical challenges induced by itself, clinical research and complexity of brain function has put forward new special fields for ethics on BCI. To ensure "responsible innovation" BCI research in healthcare and medicine, the creation of an ethical global governance framework and system, along with special guidelines for cutting-edge BCI research in medicine are suggested.

RESUMO

INTRODUCTION: To present the 3-year clinical, radiographic, and aesthetic outcomes in patients with congenitally missing lateral incisors rehabilitated with two narrow-diameter implants (NDIs). METHODS: The original population consisted of 100 patients rehabilitated with a cement-retained bi-layered zirconia single-unit crown supported by either a Ø2.9 mm (Test) or a Ø3.3 mm (Control) NDI (n = 50). At the 1- and 3-year follow-up (T2, T3), implant survival rate, crestal bone level (CBL) changes, biological, and technical complications were recorded, while the assessment of the aesthetic outcomes was performed using the Copenhagen Index Score. RESULTS: Seventy-four patients Ø2.9 mm (n = 39) or Ø3.3 mm (n = 35) reached T3, as 24 patients were lost to follow-up and 1 implant (Ø3.3 mm) was removed. Throughout the observation period, minimal CBL changes (i.e., <1 mm) were detected between groups. Despite the positive aesthetic scores recorded (i.e., 1-2), at T3 20% of patients rehabilitated with a Ø3.3 mm versus 2.6% of patients Ø2.9 mm displayed an alveolar process deficiency (Score 3). No additional technical and/or mechanical complications were recorded between T2 and T3. Tooth vitality was maintained in all neighboring teeth. Peri-implant probing depths and plaque scores remained low in both groups (p > 0.05). CONCLUSION: The use of 2.9 or 3.3 diameter implants showed comparable favorable mid-term results in terms of survival rate, CBL, and aesthetic outcomes. Hence, clinicians should rely on the use of such NDIs when replacing maxillary lateral incisors.

RESUMO

Clerodendranthus spicatus (Thunb.) C.Y.Wu (CS) is a widely studied plant that shows potential in treating urinary diseases. Previous studies have focused on its chemical composition, pharmacological effects, and clinical applications. This review aims to provide a comprehensive summary and evaluation of the existing literature on CS. It also suggests future research directions to increase our understanding of its medicinal value. 129 pieces of literature were selected from several databases, including PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), Wan-fang Database, and Google Scholar, and were analyzed. Forty-five active compounds of CS have pharmacological effects such as lowering uric acid, anti-inflammation, anti-oxidation, and kidney protection. The potential mechanisms of these effects may be related to inhibiting transforming growth factor ß1 (TGF-ß1) activation, reducing inflammatory factors such as IL-8, IL-1ß, TNF-α, PGE2, IFN-γ, and IL-6 levels, suppressing the activation of NF-κB, JAK/STAT pathway, enhancing the clearance of ROS, MDA DPPH·, and O2 ̇ -, and regulating the expression of apoptosis-related pathways and proteins. This paper also discusses the quality control of CS and its efficacy and safety in treating urinary diseases. The study concludes that CS has a high potential for treating urinary diseases. Future studies should focus on observing the metabolic changes of CS active compounds in vivo and investigating the effects of CS on key signaling pathways. Additionally, more standardized and reasonable clinical studies and safety evaluation experiments should be conducted to obtain more clinical data.
