Sarcoidosis associated pleural effusion: A case series and review.

Sarcoidosis is a multisystem disease most commonly affecting the lungs but also can rarely manifest as pleural effusions. Sarcoidosis associated pleural effusion occurs in around 1% of patients with sarcoidosis. Pleural fluid is typically exudative, lymphocyte predominant, with high pleural protein levels and normal or mildly elevated lactate dehydrogenase. Diagnosis involves excluding other etiologies of this pleural effusion and can be made clinically or definitively with pleural biopsy showing noncaseating granulomas. Treatment involves corticosteroids to which patients typically have an excellent response with resolution of the pleural effusion.

The role of exo-miRNA in diagnosis and treatment of cancers, focusing on effective miRNAs in colorectal cancer.

Small extracellular (EV) particles known as exosomes are released by a variety of cell types, including immune system cells, stem cells, and tumor cells. They are regarded as a subgroup of EVs and have a diameter that ranges from 30 to 150 nm. Proteins, lipids, nucleic acids (including RNA and DNA), and different bioactive compounds are among the wide range of biomolecules that make up the cargo of exosomes. Exosomes are crucial for intercellular communication because they let cells share information and signaling chemicals. They are involved in various physiological and pathological processes, including immune responses, tissue regeneration, cancer progression, and neurodegenerative diseases. In conclusion, it is essential to continue research into exosome-based cancer medicines to advance understanding, improve treatment plans, create personalized tactics, ensure safety, and speed up clinical translation.

Palliative Care for the Elderly With Heart Diseases in Tertiary Health care: A Concept Analysis.

BACKGROUND: The increasing incidence of heart failure (HF) in the elderly leads to increased mortality, hospitalization, length of hospital stay, and health care costs. Older adults often face multiple drug treatments, comorbidities, frailty, and cognitive problems, which require early palliative care. However, these patients do not receive adequate palliative care. OBJECTIVE: This concept analysis aimed to develop an in-depth understanding of palliative care for elderly patients with cardiac diseases in tertiary care. DESIGN: The analysis was guided by Walker and Avant's method, and databases were searched using keywords, such as palliative care, tertiary care, elderly, and heart. Covidence was used to review the results using the inclusion and exclusion criteria. RESULTS: The World Health Organisation's definition of palliative care is widely accepted. Palliative care for older adults with heart disease in tertiary care is preceded by chronic illness, polypharmacy, symptom burden, physical and cognitive decline, comorbidities, and psychosocial/spiritual issues. The main attributes of palliative care for this population include health care professionals and patient education, holistic patient/family-centered care, symptom management, shared decision-making, early integration, advanced care planning, and a multidisciplinary approach. Palliative care improves elderly cardiac patients' and their family satisfaction while reducing readmission, hospital stays, and unnecessary invasive procedures. CONCLUSION: Collaboration between hospitals, community organizations, transitional palliative care services, and research has the potential to improve early palliative care and the well-being of the elderly cardiac population. Advanced Practice Nurses (APNs) competencies play a crucial role in promoting palliative care in the elderly HF population.

The potential role of interleukins and interferons in ovarian cancer.

Ovarian cancer poses significant challenges and remains a highly lethal disease with limited treatment options. In the context of ovarian cancer, interleukins (ILs) and interferons (IFNs), important cytokines that play crucial roles in regulating the immune system, have emerged as significant factors influencing its development. This article provides a comprehensive review of the involvement of various ILs, including those from the IL-1 family, IL-2 family, IL-6 family, IL-8 family, IL-10 family, and IL-17 family, in ovarian cancer. The focus is on their impact on tumor growth, metastasis, and their role in evading immune responses within the tumor microenvironment. Additionally, the article conducts an in-depth examination of the oncogenic or antitumor roles of each IL in the context of ovarian cancer pathogenesis and progression. Besides, we elucidated the enhancements in the treatment of ovarian cancer through the utilization of type-I IFN and type-II IFN. Recent research has shed light on the intricate mechanisms through which specific ILs and IFNs contribute to the advancement of the disease. By incorporating recent findings, this review also seeks to inspire further investigations into unexplored mechanisms, fostering ongoing research to develop more effective therapeutic strategies for ovarian cancer. Moreover, through an in-depth analysis of IL- and IFN-associated clinical trials, we have highlighted their promising potential of in the treatment of ovarian cancer. These clinical trials serve to reinforce the significant outlook for utilizing ILs and IFNs as therapeutic agents in combating this disease.

Neonatal, Infant, and Child Mortality in India: Progress and Future Directions.

In India, considerable progress has been made in reducing child mortality rates. Despite this achievement, wide disparities persist across and socio-economic strata, and persistent challenges, such as malnutrition, poor sanitation, and lack of clean water. This paper provides a comprehensive review of the state of child health in India, examining key risk factors and causes of child mortality, assessing the coverage of child health interventions, and highlighting critical public health programs and policies. The authors also discuss future directions and recommendations for bolstering ongoing efforts to improve child health. These include state- and region-specific interventions, prioritizing social determinants of health, strengthening data systems, leveraging existing programs like the National Health Mission (NHM) and Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (PM-JAY), and the proposed Public Health Management Cadre (PHMC). The authors argue that reducing child mortality requires not only scaled-up interventions but a comprehensive approach that addresses all dimensions of health, from social determinants to system strengthening.

Implementer report: ICD-10 code F44.5 review for functional seizure disorder.

OBJECTIVE: The study aimed to measure the validity of International Classification of Diseases, 10th Edition (ICD-10) code F44.5 for functional seizure disorder (FSD) in the Veterans Affairs Connecticut Healthcare System electronic health record (VA EHR). METHODS: The study used an informatics search tool, a natural language processing algorithm and a chart review to validate FSD coding. RESULTS: The positive predictive value (PPV) for code F44.5 was calculated to be 44%. DISCUSSION: ICD-10 introduced a specific code for FSD to improve coding validity. However, results revealed a meager (44%) PPV for code F44.5. Evaluation of the low diagnostic precision of FSD identified inconsistencies in the ICD-10 and VA EHR systems. CONCLUSION: Information system improvements may increase the precision of diagnostic coding by clinicians. Specifically, the EHR problem list should include commonly used diagnostic codes and an appropriately curated ICD-10 term list for 'seizure disorder,' and a single ICD code for FSD should be classified under neurology and psychiatry.

Real-World Outcomes of Latinx Versus Non-Latinx Patients Treated With First-Line Immunotherapy for Metastatic Renal-Cell Carcinoma.

BACKGROUND: There are limited data regarding the impact of ethnicity among patients receiving immune checkpoint inhibitors. We evaluated real-world outcomes between Latinx and non-Latinx patients with metastatic renal-cell carcinoma (mRCC) treated with first-line nivolumab/ipilimumab within 2 different healthcare settings. METHODS: We performed a retrospective analysis of patients with mRCC who received nivolumab/ipilimumab within the Los Angeles County Department of Health Services (LAC-DHS), a safety-net healthcare system, and the City of Hope Comprehensive Cancer Center (COH), a tertiary oncology center, between January 1, 2015 and December 31, 2021. Progression-free survival (PFS) and overall survival (OS) were determined using the Kaplan-Meier method and covariates were adjusted using multivariate Cox proportional hazards regression. RESULTS: Of 94 patients, 40 patients (43%) were Latinx while the remainder were non-Latinx (44 pts [46%] White, 7 pts [7%] Asian, and 3 pts [3%] Other). Fifty (53%) and 44 (47%) patients received their care at COH and LAC-DHS, respectively. Most Latinx patients (95%) were treated at LAC-DHS, and most non-Latinx patients (89%) were treated at COH. Pooled analysis by ethnicity demonstrated significantly shorter PFS in Latinx versus non-Latinx patients (10.1 vs. 25.2 months, hazard ratios [HR] 3.61, 95% CI 1.96-6.66, P ≤ .01). Multivariate analysis revealed a HR of 3.41 (95% CI 1.31-8.84; P = .01). At a median follow-up of 11.0 months, the median OS was not reached in either arm at the time of data cutoff. CONCLUSION: Latinx patients with mRCC had a shorter PFS treated with frontline nivolumab/ipilimumab compared to their non-Latinx counterparts. No difference was observed in OS although these data were immature. Larger studies are needed to further interrogate the social and economic determinants of ethnicity on clinical outcomes in mRCC.

Circ_0067934 as a novel therapeutic target in cancer: From mechanistic to clinical perspectives.

Circular RNAs, as a type of non-coding RNAs, are identified in a various cell. Circular RNAs have stable structures, conserved sequence, and tissue and cell-specific level. High throughput technologies have proposed that circular RNAs act via various mechanisms like sponging microRNAs and proteins, regulating transcription factors, and scaffolding mediators. Cancer is one of the major threat for human health. Emerging data have proposed that circular RNAs are dysregulated in cancers as well as are associated with aggressive behaviors of cancer -related behaviors like cell cycle, proliferation, apoptosis, invasion, migration, and epithelial-mesenchymal transition (EMT). Among them, circ_0067934 was shown to act as an oncogene in cancers to enhance migration, invasion, proliferation, cell cycle, EMT, and inhibit cell apoptosis. In addition, these studies have proposed that it could be a promising diagnostic and prognostic biomarker in cancer. This study aimed to review the expression and molecular mechanism of circ_0067934 in modulating the malignant behaviors of cancers as well as to explore its potential as a target in cancer chemotherapy, diagnosis, prognosis and treatment.

Investigating the Effects of Hydro-alcoholic Urtica Dioica Extract and Retinoic Acid on Follicular Development: An Animal Study.

Background: Urtica dioica (UD), as a natural antioxidant, has positive effects on oocyte maturation. This study aimed to investigate the effects of hydro-alcoholic UD extract and retinoic acid on follicular development in an in vitro fertilization (IVF) condition. Methods: A total of 40 female Wistar rats were randomly divided into 5 groups: group 1 received normal saline, group 2 was given 25 mg/kg retinoic acid, group 3 was administered with 100 mg/kg UD extract, group 4 was treated with retinoic acid plus UD extract, and group 5 received 10 mg/kg olive oil. The histomorphometric parameters were analyzed, including the number of follicles, follicular atrophy, fertilized oocytes, 2-cell embryos, dead embryos, and blastocysts. Results: Retinoic acid caused a significant increase in the primary, preantral, and atretic follicles and a substantial decrease in the corpus luteum compared with the control group (p<0.001). The number of preantral, antral follicles, and corpus luteum was significantly higher in group 3 compared with group 1 (p<0.001). Moreover, coadministration of UD plus retinoic acid (group 4) significantly reduced the atretic follicles (p<0.05). Conclusion: Based on the results, UD herbal extract, as a natural antioxidant agent, could reduce the adverse effects of retinoic acid on oocyte maturation in an IVF condition.

Health and nutrition claims for infant formula: international cross sectional survey.

OBJECTIVES: To review available health and nutrition claims for infant formula products in multiple countries and to evaluate the validity of the evidence used for substantiation of claims. DESIGN: International cross sectional survey. SETTING: Public facing and healthcare professional facing company owned or company managed formula industry websites providing information about products marketed for healthy infants delivered at full term in 15 countries: Australia, Canada, Germany, India, Italy, Japan, Nigeria, Norway, Pakistan, Russia, Saudi Arabia, South Africa, Spain, the United Kingdom, and the United States in 2020-22. MAIN OUTCOME MEASURES: Number and type of claims made for each product and ingredient. References cited were reviewed and risk of bias was assessed for registered clinical trials using the Cochrane risk of bias tool, and for systematic reviews using the Risk Of Bias in Systematic reviews tool. RESULTS: 757 infant formula products were identified, each with a median of two claims (range from 1 (Australia) to 4 (US)), and 31 types of claims across all products. Of 608 products with ≥1 claims, the most common claim types were "helps/supports development of brain and/or eyes and/or nervous system" (323 (53%) products, 13 ingredients), "strengthens/supports a healthy immune system" (239 (39%) products, 12 ingredients), and "helps/supports growth and development" (224 (37%) products, 20 ingredients). 41 groups of ingredients were associated with ≥1claims, but many claims were made without reference to a specific ingredient (307 (50%) products). The most common groups of ingredients cited in claims were long chain polyunsaturated fatty acids (278 (46%) products, 9 different claims); prebiotics, probiotics, or synbiotics (225 (37%) products, 19 claims); and hydrolysed protein (120 (20%) products, 9 claims). 161/608 (26%) products with ≥1 claims provided a scientific reference to support the claim-266 unique references were cited for 24 different claim types for 161 products. The reference types most frequently cited were clinical trials (50%, 134/266) and reviews (20%, 52/266). 28% (38/134) of referenced clinical trials were registered, 14% (19/134) prospectively. 58 claims referred to 32 registered clinical trials, of which 51 claims (27 trials) related to a randomised comparison. 46 of 51 claims (90%) referenced registered clinical trial outcomes at high risk of bias, and all cited systematic reviews and pooled analyses, carried a high risk of bias. CONCLUSIONS: Most infant formula products had at least one health and nutrition claim. Multiple ingredients were claimed to achieve similar health or nutrition effects, multiple claims were made for the same ingredient type, most products did not provide scientific references to support claims, and referenced claims were not supported by robust clinical trial evidence.

Applying Lean Kaizen to Improve Timely Computed Tomography Scan Appointments for Oncology Patients in a Safety Net Hospital.

PURPOSE: Timely radiographic studies are essential to oncology care. At our institution, a safety net hospital in a large metropolitan area, baseline assessment determined that the overwhelming majority of outpatient computed tomographic (CT) scans for oncology patients were overdue and not scheduled within 2 weeks of their first requested date. METHODS: We conducted a series of structured, interdisciplinary meetings including staff from radiology, oncology, scheduling, and administration to critically review the scheduling process utilizing Lean Kaizen quality improvement methods. A new workflow was developed in which clinic staff scheduled CT scans before clinic discharge. Three months after our initial meeting, the new workflow was launched. We set a target of decreasing the percentage of overdue scans to below 20%. RESULTS: At baseline, 87% (65 of 75) of CT scans awaiting scheduling were overdue. Data were gathered at 5 and 10 weeks after implementation of our workflow. The percentage of CT scans overdue for scheduling was 17% (9 of 53) at 5 weeks and 0.97% (1 of 103) at 10 weeks after implementation. Clinic visit durations were not affected. CONCLUSION: The Lean Kaizen QI model was successful in decreasing the rate of oncology patients overdue for CT scan scheduling with minimal effects on clinic visit durations. This study demonstrated the importance of interdepartmental collaboration and continuous monitoring for improvement. Given the success of this project, this workflow will be expanded to other outpatient clinics within our institution.

Contributions of Parasympathetic Arousal-Related Activity to Cognitive Performance in Patients With First-Episode Psychosis and Control Subjects.

BACKGROUND: Cognitive impairment is integral to the pathophysiology of psychosis. Recent findings implicate autonomic arousal-related activity in both momentary fluctuations and individual differences in cognitive performance. Although altered autonomic arousal is common in patients with first-episode psychosis (FEP), its contribution to cognitive performance is unknown. METHODS: A total of 24 patients with FEP (46% male, age = 24.31 [SD 4.27] years) and 24 control subjects (42% male, age = 27.06 [3.44] years) performed the Multi-Source Interference Task in-scanner with simultaneous pulse oximetry. First-level models included the cardiac-blood oxygen level-dependent regressor, in addition to task (congruent, interference, and error) and nuisance (motion and CompCor physiology) regressors. The cardiac-blood oxygen level-dependent regressor reflected parasympathetic arousal-related activity and was created by convolving the interbeat interval at each heartbeat with the hemodynamic response function. Group models examined the effect of group or cognitive performance (reaction times × error rate) on arousal-related and task activity, while controlling for sex, age, and framewise displacement. RESULTS: Parasympathetic arousal-related activity was robust in both groups but localized to different regions for patients with FEP and healthy control subjects. Within both groups, arousal-related activity was significantly associated with cognitive performance across occipital and temporal cortical regions. Greater arousal-related activity in the bilateral prefrontal cortex (Brodmann area 9) was related to better performance in healthy control subjects but not patients with FEP. CONCLUSIONS: Autonomic arousal circuits contribute to cognitive performance and the pathophysiology of FEP. Arousal-related functional activity is a novel indicator of cognitive ability and should be incorporated into neurobiological models of cognition in psychosis.

Orbital apex inflammation: a curious case of COVID-19.

A 25-year-old man presented to an urgent care facility with sudden loss of vision in his right eye, diplopia, and anosmia. He tested positive by reverse-transcription polymerase chain reaction for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. Nine days later, he presented at our emergency department, at which time ophthalmic examination revealed reduced visual acuity in the right eye, with poor color vision and a relative afferent pupillary defect. He had a moderate adduction deficit and mild hypertropia of the right eye, with an intermittent exotropia. Magnetic resonance imaging of the orbits revealed asymmetric, abnormal enhancement of the right optic nerve sheath extending to the right orbital apex. His ocular symptoms resolved completely with systemic steroids. All infectious and inflammatory labs returned negative except for COVID-19. Ocular findings have been consistently implicated throughout this pandemic. This case highlights an unidentified presentation with optic nerve involvement and orbital inflammation.

COVID-19, Vaccination, and Conspiracies: A Micro-Level Qualitative Study in Islamabad, Pakistan.

Although vaccination is the only hope to fight against COVID-19, existing vaccine hesitancy is a thought-provoking phenomenon. Significantly, vaccine hesitancy is worsening the situation in Pakistan, leading to an increased number of COVID cases. In this context, this study aims to examine people's perceptions and attitudes towards vaccination. Here the focus was on determining the factors causing disease hesitancy among the masses. The researchers randomly selected a sample of n=17 individuals and gathered data by using telephone interviews and assessed data by using the Interpretive Phenomenological Analysis (IPA) approach. Results revealed that the increased vaccine hesitancy is due to misinformation, conspiracies, myths, and rumors about the side effects of the vaccination. It was also notable that the participants indicated digital media as the primary source of information, showing a potential relationship between social media and misinformation. Also, an intense uncertainty about the healthcare system in Pakistan is hindering the efforts to sustain herd immunity. Thus, due to several myths, rumors, and distrust of the healthcare system, vaccine hesitancy is halting the country's ability to overcome the COVID-19 outbreak. Misinformation is vigorously circulating due to ease of access to different communication platforms, instilling fear of presumed side effects. Hence, the researchers suggest some practical considerations for the government, healthcare workers, and media platforms to counteract the misinformation and increase vaccine acceptance among the masses.

Digital interventions to improve adherence to maintenance medication in asthma.

BACKGROUND: Asthma is the most common chronic lung condition worldwide, affecting 334 million adults and children globally. Despite the availability of effective treatment, such as inhaled corticosteroids (ICS), adherence to maintenance medication remains suboptimal. Poor ICS adherence leads to increased asthma symptoms, exacerbations, hospitalisations, and healthcare utilisation. Importantly, suboptimal use of asthma medication is a key contributor to asthma deaths. The impact of digital interventions on adherence and asthma outcomes is unknown. OBJECTIVES: To determine the effectiveness of digital interventions for improving adherence to maintenance treatments in asthma. SEARCH METHODS: We identified trials from the Cochrane Airways Trials Register, which contains studies identified through multiple electronic searches and handsearches of other sources. We also searched trial registries and reference lists of primary studies. We conducted the most recent searches on 1 June 2020, with no restrictions on language of publication. A further search was run in October 2021, but studies were not fully incorporated. SELECTION CRITERIA: We included randomised controlled trials (RCTs) including cluster- and quasi-randomised trials of any duration in any setting, comparing a digital adherence intervention with a non-digital adherence intervention or usual care. We included adults and children with a clinical diagnosis of asthma, receiving maintenance treatment. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures for data collection. We used GRADE to assess quantitative outcomes where data were available. MAIN RESULTS: We included 40 parallel randomised controlled trials (RCTs) involving adults and children with asthma (n = 15,207), of which eight are ongoing studies. Of the included studies, 30 contributed data to at least one meta-analysis. The total number of participants ranged from 18 to 8517 (median 339). Intervention length ranged from two to 104 weeks. Most studies (n = 29) reported adherence to maintenance medication as their primary outcome; other outcomes such as asthma control and quality of life were also commonly reported. Studies had low or unclear risk of selection bias but high risk of performance and detection biases due to inability to blind the participants, personnel, or outcome assessors. A quarter of the studies had high risk of attrition bias and selective outcome reporting. We examined the effect of digital interventions using meta-analysis for the following outcomes: adherence (16 studies); asthma control (16 studies); asthma exacerbations (six studies); unscheduled healthcare utilisation (four studies); lung function (seven studies); and quality of life (10 studies). Pooled results showed that patients receiving digital interventions may have increased adherence (mean difference of 14.66 percentage points, 95% confidence interval (CI) 7.74 to 21.57; low-certainty evidence); this is likely to be clinically significant in those with poor baseline medication adherence. Subgroup analysis by type of intervention was significant (P = 0.001), with better adherence shown with electronic monitoring devices (EMDs) (23 percentage points over control, 95% CI 10.84 to 34.16; seven studies), and with short message services (SMS) (12 percentage points over control, 95% CI 6.22 to 18.03; four studies). No significant subgroup differences were seen for interventions having an in-person component versus fully digital interventions, adherence feedback, one or multiple digital components to the intervention, or participant age. Digital interventions were likely to improve asthma control (standardised mean difference (SMD) 0.31 higher, 95% CI 0.17 to 0.44; moderate-certainty evidence) - a small but likely clinically significant effect. They may reduce asthma exacerbations (risk ratio 0.53, 95% CI 0.32 to 0.91; low-certainty evidence). Digital interventions may result in a slight change in unscheduled healthcare utilisation, although some studies reported no or a worsened effect. School or work absence data could not be included for meta-analysis due to the heterogeneity in reporting and the low number of studies. They may result in little or no difference in lung function (forced expiratory volume in one second (FEV1)): there was an improvement of 3.58% predicted FEV1, 95% CI 1.00% to 6.17%; moderate-certainty evidence); however, this is unlikely to be clinically significant as the FEV1 change is below 12%. Digital interventions likely increase quality of life (SMD 0.26 higher, 95% CI 0.07 to 0.45; moderate-certainty evidence); however, this is a small effect that may not be clinically significant. Acceptability data showed positive attitudes towards digital interventions. There were no data on cost-effectiveness or adverse events. Our confidence in the evidence was reduced by risk of bias and inconsistency. AUTHORS' CONCLUSIONS: Overall, digital interventions may result in a large increase in adherence (low-certainty evidence). There is moderate-certainty evidence that digital adherence interventions likely improve asthma control to a degree that is clinically significant, and likely increase quality of life, but there is little or no improvement in lung function. The review found low-certainty evidence that digital interventions may reduce asthma exacerbations. Subgroup analyses show that EMDs may improve adherence by 23% and SMS interventions by 12%, and interventions with an in-person element and adherence feedback may have greater benefits for asthma control and adherence, respectively. Future studies should include percentage adherence as a routine outcome measure to enable comparison between studies and meta-analysis, and use validated questionnaires to assess adherence and outcomes.

Autophagy-related chemoradiotherapy sensitivity in non-small cell lung cancer (NSCLC).

Lung cancer is one of the leading causes of tumor-related mortalities worldwide. NSCLC is the most common type of lung cancer. In recent years, advancements in chemoradiotherapy and immunotherapy have led to unprecedented survival benefits in some patients. However, conventional therapies such as radiation and chemotherapy are not effective in all patients due to the chemo or radioresistance mechanisms; as a result, there is an urgent need for understanding the resistant mechanism. Given that malignancies are caused by changes in cell homeostasis, autophagy may help chemo/radiosensitization by removing damaged compartments and enhancing tumor clearance. Autophagy, on the other hand, may help cancer cells survive by increasing the breakdown of cell cycle regulators. Considering these inconsistencies, this study aimed to overview the intricacy of autophagy in response to chemoradiotherapy in lung cancer.

Is there any difference in the development of mandibular third molars according to the type of impaction: An orthopantomographic study in south Indian children and adolescents.

Development of third molars and their influence on the dental arch is a major concern in clinical dentistry especially, orthodontics and oral surgery. Lately, their position, eruption potential and development has become a subject of interest in forensic practice. The present study was aimed to determine whether if there is any difference in the development of the mandibular third molars according to the impaction type. Orthopantomographs (n = 1112) from 478 males and 634 females between 15 and 22 years old were analysed. In each radiograph, impaction status and the developmental stage of mandibular third molars were determined. Descriptive statistics were performed at developmental stages D to H. For stage G, there was a delay by 0.74 and 0.62 years for mesioangular impaction, 0.89 and 0.33 years for horizontal impaction, 1.43 and 0.9 years for distoangular impaction and 1.74 and 1.1 years for vertical impaction, in males and females. For stage H, delay by 0.17 and 0.74 years, 0.05 and 0.06 years, 0.48 and 1.48 years and 0.62 and 0.62 years, respectively for all impaction variants in both sexes. Mean chronological age of the distoangular and vertically impacted mandibular third molars were higher in certain developmental stages than mesioangular and horizontal impactions. Our findings concluded that distoangular and vertical impaction variants mineralize more slowly than mesioangular and horizontal variants, however these differences were smaller. Therefore, no distinction is required between impaction types for dental age estimation especially in the prediction of the age of majority (18 years).

Systemic Therapy for Chondrosarcoma.

OPINION STATEMENT: Clinical trial enrollment should be actively encouraged in all patients diagnosed with advanced, surgically unresectable chondrosarcoma (CS) due to the lack of consensus treatment recommendations. In the absence of an appropriate clinical trial, treatments are determined based on histologic subtype of CS with consideration given to targetable mutations (i.e., IDH1). Conventional CS is inherently resistant to cytotoxic chemotherapy and patients may benefit from antiangiogenic therapy including off-label use of pazopanib. Individuals harboring an IDH1 mutation may derive clinical benefit from ivosidenib, an IDH1 inhibitor. Upon progression and with functional status permitting, alternative options include mTOR inhibitors (sirolimus, temsirolimus) or other tyrosine kinase inhibitors (dasatinib), though no clear sequencing data exists. For dedifferentiated CS, conventional chemotherapies with osteosarcoma-like regimens are upfront options although prospective data is limited with minimal overall benefit. Alternative treatment options include immunotherapy with pembrolizumab or ivosidenib in IDH1-mutant, dedifferentiated CS, but questionable efficacy was observed in small sample sizes with either approach. In mesenchymal CS, treatment with Ewing sarcoma-like chemotherapy regimens may be considered, although data supporting its use is even more limited given its rarity.

Dual-layer spectral CT virtual-non-contrast images aid in parathyroid adenoma analysis and radiation dose reduction: confirmation of findings from dual-energy CT.

4D-parathyroid CT scans have become a mainstay in the evaluation and pre-surgical planning for parathyroid adenomas. Most protocols typically rely on non-contrast images, prior to the arterial and delayed phases. Previous reports with dual-energy CT imaging have highlighted the utility of virtual non-contrast images to help reduce radiation dose while maintaining diagnostic accuracy. Herein, we report two cases of surgically proven parathyroid adenomas diagnosed with 4D-parathyroid CT scans performed on dual-layer spectral scanners, and in retrospect highlight the utility of virtual non-contrast images. To our knowledge, this report provides the first description of virtual non-contrast images from dual-layer spectral CT scanners that could aid in the diagnosis of parathyroid adenomas, confirming similar findings described with dual-energy CT scanners.
