RESUMO

OBJECTIVE: The objective of this discussion paper is to illuminate the importance of early identification and treatment of Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN). SJS/TEN may occur as quickly as 4 days, more commonly 4 to 8 weeks after starting a new medication and early identification is essential. METHODS: A review of literature revealed there is a lack of diagnostic awareness related to the clinical presentation and diverse populations at risk for this devastating syndrome. RESULTS: A Boolean search was conducted, and six quantitative and qualitative research articles were discovered that indicate a knowledge disparity between "rash" versus SJS/TEN. Research indicates evidence-based best clinical practices for nurses and health care practitioners for assessment of risks, clinical presentation, and treatment. CONCLUSIONS: Prompt diagnosis and discontinuation of the suspected medication will reduce potential life-threatening sequelae.

RESUMO

Risk assessment tools used to assess justice-involved women have been predominantly developed using male offenders, with validations for females having mixed results. Female-specific risk assessment tools are not well established, and validations are limited. In terms of treatment, either programmes in various jurisdictions have been developed specifically for females, or addendums are available to assist in the facilitation of programmes initially developed for male offenders. The efficacy of these has been varied with gender-responsive programmes proving to be more successful in the reduction of reoffending if justice-involved women follow a gender-specific pathway to offending than if they follow a non-gender-specific pathway. This paper discusses gender differences in offending and provides an overview of assessment and treatment of justice-involved women in Australia, the UK, New Zealand and Canada. The assessment and treatment practices for justice-involved women are viewed through an evidence-based lens, and opportunities for future development are identified.

RESUMO

OBJECTIVE: Cannabis use for medical condition has significantly increased over the past 20 years with 33 states and the District of Columbia passing laws legalizing medical cannabis. Five qualifying psychiatric disorders have been identified. The objective of this review article is to present a brief history of medical cannabis, the evidence for the qualifying psychiatric conditions, and to discuss the implications for psychiatric nurses. METHOD: A review of the literature on the five qualifying psychiatric disorders was conducted. Databases searched included CINAHL, PubMed, Cochrane Library, MedLine Plus, and EMBASE. Keywords were cannabis, medical cannabis, delta-9-tetrahydrocannabinaol, cannabidiol, and psychiatric disorders. RESULTS: The evidence that medical cannabis or cannabinoids is an effective treatment for the qualifying psychiatric disorders (e.g., posttraumatic stress disorder, agitation in Alzheimer's disease and other dementias, Tourette's syndrome, anxiety, and obsessive-compulsive disorder) is too weak and of low quality to recommend as an intervention at this time. A discussion of the implications of these findings for psychiatric nurses is offered based on the published guidelines by the American Nurses Association and National Council of State Boards of Nursing. CONCLUSION: There is a significant gap between evidence supporting the effectiveness of medical cannabis for psychiatric disorders and patient interest and use of cannabis for such conditions as well as other psychiatric symptoms. There are tremendous opportunities for psychiatric nurses to make an impact both clinically and be conducting research in this emerging field. We need to educate ourselves and our patients about the benefits and risks of medical cannabis and to help patients make informed decisions about their health care.

RESUMO

Niemann-Pick type C (NPC) disease is a rare lysosomal storage disorder caused by mutations in either the NPC1 or the NPC2 gene. A new class of lipids, N-acyl-O-phosphocholineserines were recently identified as NPC biomarkers. The most abundant species in this class of lipid, N-palmitoyl-O-phosphocholineserine (PPCS), was evaluated for diagnosis of NPC disease and treatment efficacy assessment with 2-hydroxypropyl-ß-cyclodextrin (HPßCD) in NPC. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods were developed and validated to measure PPCS in human plasma and cerebrospinal fluid (CSF). A cutoff of 248 ng/mL in plasma provided a sensitivity of 100.0% and specificity of 96.6% in identifying NPC1 patients from control and NPC1 carrier subjects. PPCS was significantly elevated in CSF from NPC1 patients, and CSF PPCS levels were significantly correlated with NPC neurological disease severity scores. Plasma and CSF PPCS did not change significantly in response to intrathetical (IT) HPßCD treatment. In an intravenous (IV) HPßCD trial, plasma PPCS in all patients was significantly reduced. These results demonstrate that plasma PPCS was able to diagnose NPC1 patients with high sensitivity and specificity, and to evaluate the peripheral treatment efficacy of IV HPßCD treatment.

RESUMO

Niemann-Pick disease type C (NPC) is a neurodegenerative disease in which mutation of NPC1 or NPC2 gene leads to lysosomal accumulation of unesterified cholesterol and sphingolipids. Diagnosis of NPC disease is challenging due to non-specific early symptoms. Biomarker and genetic tests are used as first-line diagnostic tests for NPC. In this study, we developed a plasma test based on N-(3ß,5α,6ß-trihydroxy-cholan-24-oyl)glycine (TCG) that was markedly increased in the plasma of human NPC1 subjects. The test showed sensitivity of 0.9945 and specificity of 0.9982 to differentiate individuals with NPC1 from NPC1 carriers and controls. Compared to other commonly used biomarkers, cholestane-3ß,5α,6ß-triol (C-triol) and N-palmitoyl-O-phosphocholine (PPCS, also referred to as lysoSM-509), TCG was equally sensitive for identifying NPC1 but more specific. Unlike C-triol and PPCS, TCG showed excellent stability and no spurious generation of marker in the sample preparation or aging of samples. TCG was also elevated in lysosomal acid lipase deficiency (LALD) and acid sphingomyelinase deficiency (ASMD). Plasma TCG was significantly reduced after intravenous (IV) 2-hydroxypropyl-ß-cyclodextrin (HPßCD) treatment. These results demonstrate that plasma TCG was superior to C-triol and PPCS as NPC1 diagnostic biomarker and was able to evaluate the peripheral treatment efficacy of IV HPßCD treatment.

RESUMO

BACKGROUND: Weight assessment is a key component of nursing care for individuals with the acute illness of anorexia nervosa (AN). However, there is little data to guide protocols and procedures regarding weight assessment. OBJECTIVE: To describe institutional practices regarding weight assessment of individuals during acute illness of AN. DESIGN: Treatment facilities ( N = 24) completed a survey about written protocols and procedures regarding weight assessment and disclosure of weight to patients. RESULTS: The majority of facilities ( n = 22; 92%) have written protocols for weight assessment. Weight assessments occurred mostly in the morning ( n = 23; 95.8%), in hospital gowns ( n = 21; 87.5%), and after voiding ( n = 14; 58.3%). Respondents described mixed practices for disclosing weight to patients. CONCLUSION: Results indicate widespread variability in weight assessment and disclosure of weight. Further research is necessary to help develop evidence-based guidelines about weighing practices during acute illness for individuals with AN.

RESUMO

Thermal ablation with high intensity focused ultrasound (HIFU) is an emerging noninvasive technique for the treatment of solid tumors. HIFU treatment of malignant tumors requires accurate treatment planning, monitoring and evaluation, which can be facilitated by performing the procedure in an MR-guided HIFU system. The MR-based evaluation of HIFU treatment is most often restricted to contrast-enhanced T1 -weighted imaging, while it has been shown that the non-perfused volume may not reflect the extent of nonviable tumor tissue after HIFU treatment. There are multiple studies in which more advanced MRI methods were assessed for their suitability for the evaluation of HIFU treatment. While several of these methods seem promising regarding their sensitivity to HIFU-induced tissue changes, there is still ample room for improvement of MRI protocols for HIFU treatment evaluation. In this review article, we describe the major acute and delayed effects of HIFU treatment. For each effect, the MRI methods that have been-or could be-used to detect the associated tissue changes are described. In addition, the potential value of multiparametric MRI for the evaluation of HIFU treatment is discussed. The review ends with a discussion on future directions for the MRI-based evaluation of HIFU treatment.

RESUMO

AIM: Accurate assessment of the coagulated area is imperative to achieve an excellent outcome from percutaneous radiofrequency ablation (PRFA) for the treatment of hepatocellular carcinoma (HCC). We evaluated the efficacy of contrast-enhanced ultrasonography (CEUS) with the contrast-enhancing agent Sonazoid for precisely assessing the therapeutic effect of PRFA for HCC. METHODS: We enrolled 87 consecutive patients with solitary naïve HCC of less than 3 cm in diameter. PRFA treatment was performed with a 17-G cool-tip needle, and CEUS was performed to assess the ablative margin 3 h after the procedure, when the coagulated tumor outline was easiest to discern. The treatment was repeated until an ablative margin greater than 5 mm was confirmed. After CEUS assessment of the therapeutic response, the patients were followed to investigate local tumor recurrence. RESULTS: In 78 patients (89.7%), the outline of the coagulated tumors could be recognized by ultrasonography, and CEUS assessment of the ablative margin was successful. The remaining nine patients were assessed by computed tomography. The 5-year cumulative survival rate after the assessment of the treatment response with CEUS was 58.4%, and the 4-year cumulative total recurrence rate was 72.3%. The 5-year cumulative local tumor recurrence rate was very low (2.3%). CONCLUSION: The assessment with CEUS at 3 h after the PRFA procedure was successful in the majority of the patients, and it yielded a very low rate of local recurrence.

RESUMO

BACKGROUND: Falls are the leading cause of injury-related deaths among people age 65 and older, and fractures are the major category of serious injuries produced by falls. OBJECTIVE: Determine market segment-specific recommendations for "selling" falls prevention in acute inpatient psychiatry. DESIGN: Descriptive using focus groups. SETTING: One inpatient unit at a Veterans' hospital in the Southeastern United States and one national conference of psychiatric and mental health nurses. PATIENTS: A convenience sample of 22 registered nurses and advanced practice nurses, one physical therapist and two physicians participated in one of six focus groups. INTERVENTION: None. MEASUREMENTS: Focus groups were conducted by expert facilitators using a semistructured interview guide. Focus groups were recorded and transcribed. Content analysis was used to organize findings. RESULTS: Findings were grouped into fall risk assessment, clinical fall risk precautions, programmatic fall prevention, and "selling" fall prevention in psychiatry. Participants focused on falls prevention instead of fall injury prevention, were committed to reducing risk, and were receptive to learning how to improve safety. Participants recognized unique features of their patients and care settings that defined risk, and were highly motivated to work with other disciplines to keep patients safe. CONCLUSIONS: Selling fall injury prevention to staff in psychiatric settings is similar to selling fall injury prevention to staff in other health care settings. Appealing to the larger construct of patient safety will motivate staff in psychiatric settings to implement best practices and customize these to account for unique population needs characteristics.

RESUMO

INTRODUCTION: Currently, assessing ADHD treatment response to stimulants relies on rating scales and subjective questionnaires and sometimes a CPT. Such tools fall short of objective, quantifiable measurement of effect, especially in natural settings and can result in inconsistent treatment. METHOD: We report results from two studies using a novel proof-of-concept approach. A preliminary trial of 10 individuals used a high-fidelity eye tracker; a second study of 100 individuals used webcams at the participants' homes. RESULTS: Both studies evaluated stimulant effect using reading behavior analysis, being an ADHD symptom that stimulants affect and a major symptom patients want to improve. Both showed a significant change in reading behavior related to medication state, suggesting a clear, objective measure of stimulant effect. CONCLUSION: Using ubiquitous hardware, investigators created a user-friendly treatment assessment platform where individuals can collect their own objective data within minutes in any setting where they have access to a web camera and computer.

RESUMO

BACKGROUND: Prepubertal girls are one of the vulnerable populations of vulvar lichen sclerosus (VLS), which results in a decreased quality of life and increases risk of vulvar cancer. But the therapeutic effects of traditional topical remedies are unsatisfactory in some pediatric patients. 5-Aminolevulinic acid photodynamic therapy (ALA-PDT) is an effective treatment for refractory VLS patients, but no study has been conducted in child patients. METHODS: The patients included in this study underwent three sessions of ALA-PDT at 2-week intervals. All patients were evaluated for objective clinical appearances and subjective symptoms quantitatively. Statistical analysis comparing parameters at baseline and after three-time ALA-PDT was performed. RESULTS: A total of seven VLS girl patients were included in this study. Both primary objective appearances (lesion size and depigmentation) and subjective symptoms (itching and burning pain) were improved remarkably after the third treatment. Besides, adverse effects, mainly as pain and post-treatment edema, were mild and could be tolerated. CONCLUSIONS: ALA-PDT is an effective and safe therapeutic option for VLS girl patients. Compared with adult patients, the symptoms resolved more quickly in child patients.

RESUMO

Background: Addressing the critical public health crisis of substance use disorder (SUD), this study evaluates the accuracy of SUD treatment search tools, such as FindTreatment.gov, to connect patients with appropriate care. Methods: To ensure geographic diversity, we randomly selected one state from four distinct US regions (Arizona, Florida, Massachusetts, Ohio) and then randomly selected counties of varying sizes (one large, two medium, three small) within each state using a random number generator. Contact information for practices was extracted from the tools and validated through phone calls. The primary outcome measures were exact accuracy rate (wherein all information was accurate) and functional accuracy rate (wherein enough information was provided to facilitate care establishment). Results: A total of 697 practices from within ten SUD treatment search tools were assessed. Accuracy of the ten SUD treatment search tools varied considerably, with exact accuracy rates ranging from 9.1 % to 76.0 % (mean: 56.0 %) and functional accuracy rates from 50.0 % to 92.0 % (mean: 82.8 %). National tools exhibited higher accuracy for both exact accuracy rate (66.3 % v. 49.0 %; p = 0.2864) and functional accuracy rate (83.8 % v. 82.2 %; p = 0.9148) than state tools, while privately funded tools demonstrated higher accuracy for both exact accuracy rates (66.8 % v. 48.9 %; p = 0.2008) and functional accuracy rates (83.8 % v. 82.2 %; p = 0.9148), but none of these differences were statistically significant. Conclusions: This study found that SUD treatment search tools commonly list inaccurate information, underscoring the need for systematic improvements in data management and validation practices.

RESUMO

BACKGROUND: Non-proliferative diabetic retinopathy (NPDR) poses a significant challenge in diabetes management due to its microvascular changes in the retina. Laser photocoagulation, a conventional therapy, aims to mitigate the risk of progressing to proliferative diabetic retinopathy (PDR). AIM: To compare the efficacy and safety of multi-spot vs single-spot scanning panretinal laser photocoagulation in NPDR patients. METHODS: Forty-nine NPDR patients (86 eyes) treated between September 2020 and July 2022 were included. They were randomly allocated into single-spot (n = 23, 40 eyes) and multi-spot (n = 26, 46 eyes) groups. Treatment outcomes, including best-corrected visual acuity (BCVA), central macular thickness (CMT), and mean threshold sensitivity, were assessed at predetermined intervals over 12 months. Adverse reactions were also recorded. RESULTS: Energy levels did not significantly differ between groups (P > 0.05), but the multi-spot group exhibited lower energy density (P < 0.05). BCVA and CMT improvements were noted in the multi-spot group at one-month post-treatment (P < 0.05). Adverse reaction incidence was similar between groups (P > 0.05). CONCLUSION: While energy intensity and safety were comparable between modalities, multi-spot scanning demonstrated lower energy density and showed superior short-term improvements in BCVA and CMT for NPDR patients, with reduced laser-induced damage.

RESUMO

This scoping review examines the contemporary applications of advanced artificial intelligence (AI) software in orthodontics, focusing on its potential to improve daily working protocols, but also highlighting its limitations. The aim of the review was to evaluate the accuracy and efficiency of current AI-based systems compared to conventional methods in diagnosing, assessing the progress of patients' treatment and follow-up stability. The researchers used various online databases and identified diagnostic software and dental monitoring software as the most studied software in contemporary orthodontics. The former can accurately identify anatomical landmarks used for cephalometric analysis, while the latter enables orthodontists to thoroughly monitor each patient, determine specific desired outcomes, track progress, and warn of potential changes in pre-existing pathology. However, there is limited evidence to assess the stability of treatment outcomes and relapse detection. The study concludes that AI is an effective tool for managing orthodontic treatment from diagnosis to retention, benefiting both patients and clinicians. Patients find the software easy to use and feel better cared for, while clinicians can make diagnoses more easily and assess compliance and damage to braces or aligners more quickly and frequently.

RESUMO

Background: Transcription factors in Foxo signaling pathway influence hepatocellular carcinoma metastasis through epithelial mesenchymal transition-related pathways. Prognostic factors in the Foxo signaling pathway are feasible for HCC prognosis and therapeutic management. Methods: Based on the differentially expressed genes and Foxo signaling pathway genes in HCC, the ConsensusClusterPlus package was conducted to identify Foxo signaling pathway-related molecular subtypes in HCC. Based on the DEGs in the FMSs, the optimal prognostic factors in HCC were screened by cox and least absolute shrinkage and selection operator (LASSO) cox analysis to form the Foxo prognosis score (FPS). The prognostic predictive effectiveness of FPS was assessed by Kaplan Meier (K-M) analysis and Receiver Operating Characteristic (ROC) analysis. Additionally, tumor microenvironment (TME) score, tumor mutation burden (TMB) and treatment sensitivity differences in FMSs and FPS groups were also evaluated. Results: There were low, medium and high Foxo signaling pathway activity molecular subtypes in HCC named FMS 1, FMS 2 and FMS 3, respectively. FMS 1 with lowest Foxo signaling pathway activity presented an excellent survival advantage, while FMS 3 with highest Foxo signaling pathway activity exhibited an inhibitory TME status. According to FPS grouping, low FPS exhibited favorable survival, low TMB and anti-tumor activity. Patients in the low FPS group were mostly in the early stage of cancer. Moreover, we found that patients with high and low FPS exhibited different sensitivity to chemotherapy, and patients with low FPS were more sensitive to immunotherapy. Conclusion: We revealed a novel molecular subtype and prognostic tool based on Foxo signaling pathway signature, which could potentially provide a direction for accurate and effective assessment of potential personalized treatment options and prognostic management for HCC patients.

RESUMO

Background: Extremity soft-tissue sarcomas (STS) are commonly treated with neoadjuvant radiation therapy followed by surgical resection. However, the pathological near-complete response rate is low (9-25%). Noninvasive imaging assessment that predicts treatment response before and during treatment is desirable to optimize treatment regimens. This pilot study aimed to investigate the application of a quantitative MRI parameter, T2*, in assessing neoadjuvant radiation therapy combined with pharmacological ascorbate in extremity STS. Methods: This prospective cohort study included seven patients diagnosed with extremity STS and scheduled to receive neoadjuvant radiation therapy combined with pharmacological ascorbate. T2* maps were obtained from each patient before treatment (baseline MRI), two weeks after initiating treatment (on-treatment MRI), and before surgery (pre-surgery MRI). The T2* values within the tumor region were transformed into z-scores with respect to the normal- appearing tissue region. The voxel-wise z-scores within the tumor region were thresholded to generate masks representing significantly high (z-score>1.96) and low z-score (z-score<-1.96) voxels. The means of the total z-scores and within each of the significantly high and low z-score mask were computed. Their correlations with percent necrosis from pathological examination were evaluated using Spearman's rank correlation coefficient r. A correlation was considered as moderate or strong when r is higher than 0.6 and 0.8, respectively. A correlation was considered as fair or weak when r is below 0.6. Results: For the baseline and on-treatment MRIs, the means of the significantly high z-scores of the T2* measurements showed moderate correlations with percent necrosis (r = 0.68 and 0.6; p = 0.11 and 0.24). For the pre-surgery MRI, the means of the total and significantly high z-scores showed strong correlations with percent necrosis (r = 0.8 and 0.9; p = 0.13 and 0.08). Tumor volume and baseline MRI-based percent necrosis showed fair or weak correlations (r = 0.3-0.54; p = 0.24-0.68). Conclusion: T2* measurements prior to treatment, two weeks after initiating treatment, and before surgery showed moderate to strong correlations with percent necrosis. These results support the potential for using T2* mapping to predict and assess response to neoadjuvant radiation therapy combined with pharmacological ascorbate in extremity STS. Level of Evidence: IV.

RESUMO

BACKGROUND: Patients with vulvar lichen sclerosus (VLS) are faced with a decreased quality of life and an increased risk of vulvar malignancy. 5-Aminolevulinic acid-based photodynamic therapy (ALA-PDT) can serve as an alternative for refractory VLS patients. However, high-frequency ultrasound (HFUS) has never been introduced in the ALA-PDT outcome assessment for VLS patients. METHODS: A prospective study was conducted. Refractory VLS patients received two treatment courses of ALA-PDT (3 times of remedies at 2-week intervals for each course), and underwent clinical, HFUS and histopathological assessment. Statistical analysis comparing parameters at baseline and after ALA-PDT was performed. RESULTS: Thirty-one VLS patients were included. Both subjective symptoms (itch and burning pain) and objective severity (lesion size and hypopigmentation) were relieved significantly after ALA-PDT treatment. Hypoechoic dermal band (HDB) thickness revealed by HFUS decreased progressively with successive ALA-PDT treatment, and the reduction value had a positive correlation with the reduction of inflammatory infiltration depth in histopathology. Collagen homogenization depth decrease was also noticed. Besides, adverse effects were recorded, mainly as mild and transient post-treatment edema and pain. CONCLUSIONS: ALA-PDT is an effective and safe therapeutic option for refractory VLS patients. HFUS can act as a complement to the non-invasive treatment monitoring for its objectivity, quantifiability and precision in the distinct vertical perspective.

RESUMO

PURPOSE: Rates of at-risk opioid use, opioid use disorder, and opioid overdose remain alarmingly high. There are medications that can be used to treat opioid use disorder, including methadone, buprenorphine, and naltrexone, although access to care remains difficult. This review seeks to provide advanced practice psychiatric nurses (APPNs) with an overview of buprenorphine prescribing, with an emphasis on novel, long-acting delivery systems. CONCLUSIONS: APPNs should be familiar with best practices regarding buprenorphine prescribing. Some patients may benefit from long-acting delivery methods, such as subdermal implants, or subcutaneous injections. PRACTICE IMPLICATIONS: APPNs can reduce barriers to buprenorphine access and should be familiar with best practices related to buprenorphine prescribing.

RESUMO

Progress in understanding borderline personality disorder has unfolded in the last decade, landing in a new COVID-19-influenced world. Borderline personality disorder is now firmly established as a valid diagnosis, distinct from its co-occurring mood, anxiety, trauma-related, and behavioral disorders. Further, it is also understood as a reflection of general personality dysfunction, capturing essential features shared among all personality disorders. Neuroimaging research, representing the vast neurobiological advances made in the last decade, illustrates that the disorder shares frontolimbic dysfunction with many psychiatric diagnoses but has a distinct signature of interpersonal and emotional hypersensitivity. This signature is the conceptual basis of the psychotherapies and clinical management approaches proven effective for the disorder. Medications remain adjunctive and are contraindicated by some guidelines internationally. Less invasive brain-based therapeutics show promise. The most significant change in the treatment landscape is a focus on briefer, less intensive formats of generalist management. Shorter variants of therapies, such as dialectical behavior therapy and mentalization-based treatment, are in the process of being shown to be adequately effective. Earlier intervention and greater emphasis on functional improvement are needed to more effectively curb the disabilities and risks of borderline personality disorder for patients and their families. Remote interventions show promise in broadening access to care.

Inpatient psychiatric treatment and violence assessment are strongly influenced by a patient's race and class identity. The authors argue that psychiatrists enact a crypto-apartheid wherein they recognize and condemn the structural racism and classism disadvantaging many patients, but through violence risk assessments and dispositional decisions, psychiatrists also function as arbiters of public safety and repeatedly disadvantage less-privileged patients to further symptomatic decline or even subsequent incarceration.
