Evaluation of General Anesthesia and Sedation and Follow-Up Compliance in Pediatric Dental Procedures: A Comprehensive Analysis of Long-Term Outcomes and Gender Differences.

This retrospective study evaluated the effectiveness of different types of general anesthesia (GA) and sedation in pediatric dental procedures, focusing on treatment outcomes and follow-up compliance with an emphasis on gender differences. Clinical records of 1582 pediatric patients, aged 0-18 years, were analyzed to examine the distribution, duration and impact of anesthesia types on dental procedure complexity. The study population was divided into three age groups: 0-6, 7-12 and 13-18 years. We assessed follow-up attendance rates by gender and anesthesia type, calculated the decayed, missing and filled (DMF) index and evaluated the need for further treatment and reasons for retreatment. Our findings indicated that general anesthesia with inhalational agents and muscle relaxants was the most frequently used method (1260 instances), followed by nitrous oxide sedation (163 instances) and sevoflurane GA with a laryngeal mask airway (158 instances). Inhalational GA with muscle relaxants had the longest average duration (2.78 h) and the highest DMF index (7.43), reflecting its use in more severe dental conditions. Gender analysis revealed a slight male predominance in using inhalational GA with muscle relaxants (55.87% male vs. 44.13% female). Female patients demonstrated higher follow-up compliance across all periods. Overall, our results highlight the importance of tailored anesthesia and sedation plans, as well as follow-up protocols, in pediatric dentistry. This study provides valuable insights for practitioners in selecting appropriate anesthesia and sedation types and developing strategies to improve follow-up compliance and treatment success.

IGF-I assay methods and biologic variability: evaluation of acromegaly treatment response.

Serum insulin-like growth factor (IGF-I) is the primary biochemical measure of disease activity in patients with acromegaly, and the 2014 Endocrine Society guidelines recommended normal age-adjusted serum IGF-I as the biochemical target of treatment. However, quantification and interpretation of IGF-I levels are subject to limitations that may affect therapeutic decisions. Techniques for measuring IGF-I have evolved greatly over the past 40 years and continue to do so. Results can vary substantially for different assays, procedures, and laboratories. For any assay, the interpretation of IGF-I values requires robust reference ranges. Using currently available large normative databases, the upper limit of normal (ULN) for IGF-I in middle-aged and elderly individuals is lower than historical reference ranges. Thus, the goal of achieving IGF-I < 1× ULN is more demanding than in the past, and some patients with acromegaly who were classified as "normal" (IGF-I < 1× ULN) in previous studies would be reclassified as above the ULN based on newer normative data. In addition, substantial intra-individual, week-to-week variation in serum IGF-I levels (unrelated to assay performance) has been observed. With changes over time in the measurement of IGF-I and the advent of updated reference ranges derived from large normative databases, it is difficult to justify rigid adherence to the goal of maintaining IGF-I below the ULN for all patients with acromegaly. Instead, symptoms, comorbidities, and quality of life should be considered, along with growth hormone and IGF-I levels, when evaluating the need for further treatment.

Pituitary cyclase-activating polypeptide targeted treatmentsfor the treatment of primary headache disorders.

Migraine is a complex and disabling neurological disorder. Recent years have witnessed the development and emergence of novel treatments for the condition, namely those targeting calcitonin gene-related peptide (CGRP). However, there remains a substantial need for further treatments for those unresponsive to current therapies. Targeting pituitary adenylate cyclase-activating polypeptide (PACAP) as a possible therapeutic strategy in the primary headache disorders has gained interest over recent years. This review will summarize what we know about PACAP to date: its expression, receptors, roles in migraine and cluster headache biology, insights gained from preclinical and clinical models of migraine, and therapeutic scope. PACAP shares homology with vasoactive intestinal polypeptide (VIP) and is one of several vasoactive neuropeptides along with CGRP and VIP, which has been implicated in migraine neurobiology. PACAP is widely expressed in areas of interest in migraine pathophysiology, such as the thalamus, trigeminal nucleus caudalis, and sphenopalatine ganglion. Preclinical evidence suggests a role for PACAP in trigeminovascular sensitization, while clinical evidence shows ictal release of PACAP in migraine and intravenous infusion of PACAP triggering attacks in susceptible individuals. PACAP leads to dural vasodilatation and secondary central phenomena via its binding to different G-protein-coupled receptors, and intracellular downstream effects through cyclic adenosine monophosphate (cAMP) and phosphokinase C (PKC). Targeting PACAP as a therapeutic strategy in headache has been explored using monoclonal antibodies developed against PACAP and against the PAC1 receptor, with initial positive results. Future clinical trials hold considerable promise for a new therapeutic approach using PACAP-targeted therapies in both migraine and cluster headache.

Laparoscopic cholecystectomy versus conservative management for adults with uncomplicated symptomatic gallstones: the C-GALL RCT.

Gallstone disease is a common gastrointestinal disorder in industrialised societies. The prevalence of gallstones in the adult population is estimated to be approximately 10-15%, and around 80% remain asymptomatic. At present, cholecystectomy is the default option for people with symptomatic gallstone disease. To assess the clinical and cost-effectiveness of observation/conservative management compared with laparoscopic cholecystectomy for preventing recurrent symptoms and complications in adults presenting with uncomplicated symptomatic gallstones in secondary care. Parallel group, multicentre patient randomised superiority pragmatic trial with up to 24 months follow-up and embedded qualitative research. Within-trial cost-utility and 10-year Markov model analyses. Development of a core outcome set for uncomplicated symptomatic gallstone disease. Secondary care elective settings. Adults with symptomatic uncomplicated gallstone disease referred to a secondary care setting were considered for inclusion. Participants were randomised 1: 1 at clinic to receive either laparoscopic cholecystectomy or observation/conservative management. The primary outcome was quality of life measured by area under the curve over 18 months using the Short Form-36 bodily pain domain. Secondary outcomes included the Otago gallstones' condition-specific questionnaire, Short Form-36 domains (excluding bodily pain), area under the curve over 24 months for Short Form-36 bodily pain domain, persistent symptoms, complications and need for further treatment. No outcomes were blinded to allocation. Between August 2016 and November 2019, 434 participants were randomised (217 in each group) from 20 United Kingdom centres. By 24 months, 64 (29.5%) in the observation/conservative management group and 153 (70.5%) in the laparoscopic cholecystectomy group had received surgery, median time to surgery of 9.0 months (interquartile range, 5.6-15.0) and 4.7 months (interquartile range 2.6-7.9), respectively. At 18 months, the mean Short Form-36 norm-based bodily pain score was 49.4 (standard deviation 11.7) in the observation/conservative management group and 50.4 (standard deviation 11.6) in the laparoscopic cholecystectomy group. The mean area under the curve over 18 months was 46.8 for both groups with no difference: mean difference -0.0, 95% confidence interval (-1.7 to 1.7); p-value 0.996; n = 203 observation/conservative, n = 205 cholecystectomy. There was no evidence of differences in quality of life, complications or need for further treatment at up to 24 months follow-up. Condition-specific quality of life at 24 months favoured cholecystectomy: mean difference 9.0, 95% confidence interval (4.1 to 14.0), p < 0.001 with a similar pattern for the persistent symptoms score. Within-trial cost-utility analysis found observation/conservative management over 24 months was less costly than cholecystectomy (mean difference -£1033). A non-significant quality-adjusted life-year difference of -0.019 favouring cholecystectomy resulted in an incremental cost-effectiveness ratio of £55,235. The Markov model continued to favour observation/conservative management, but some scenarios reversed the findings due to uncertainties in longer-term quality of life. The core outcome set included 11 critically important outcomes from both patients and healthcare professionals. The results suggested that in the short term (up to 24 months) observation/conservative management may be a cost-effective use of National Health Service resources in selected patients, but subsequent surgeries in the randomised groups and differences in quality of life beyond 24 months could reverse this finding. Future research should focus on longer-term follow-up data and identification of the cohort of patients that should be routinely offered surgery. This trial is registered as ISRCTN55215960.

Use of early circulating tumour DNA dynamics in patients with stage III melanoma receiving neoadjuvant combination immunotherapy.

9577 Background: Neoadjuvant therapy in resectable stage III cutaneous melanoma improves relapse-free survival compared to adjuvant therapy alone and is now a standard of care.While pathological response can help predict recurrence risk and the need for further treatment, more biomarkers are required. We investigated circulating tumour DNA (ctDNA) as a predictive biomarker for recurrence in stage IIIB/C melanoma patients following neoadjuvant immunotherapy and surgery. Methods: We retrospectively analysed plasma samples collected at baseline and six weeks post-surgery from 30 patients enrolled in the OpACIN-neo and PRADO clinical trials, who received two cycles of ipilimumab (anti-CTLA-4) and nivolumab (anti-PD-1) before surgery. Cell free DNA (cfDNA) underwent pre-amplification followed by tumour-informed mutation detection analysis using droplet digital polymerase chain reaction (ddPCR) with the Bio-Rad QX600 PCR system. BRAF mutations were identified in 60% of patients through tumour tissue sequencing. Following neoadjuvant therapy, 7/30 (23%) achieved complete pathological response (pCR), 5/30 (17%) near pCR, 4/30 (13%) partial response, and 14/30 (47%) non-response (pNR). Results: Baseline ctDNA was detectable in 15/30 (50%) patients using the pre-amplification ddPCR method. At median follow-up of 47 months, 9/30 (30%) patients recurred, with a median time to recurrence of 8 months (range 6 to 29 months). Post-surgery, ctDNA was detectable in 4/9 patients who recurred; all four were pathological non-responders and recurred with distant, unresectable disease. Among the 15 ctDNA-positive patients at baseline, 13/15 (87%) patients achieved ctDNA clearance while 2/15 (13%) remained persistently ctDNA-positive; with a subsequent relapse rate of 0% and 100% respectively. ctDNA detection post-surgery predicted patients at higher risk of disease recurrence [relapse-free survival (RFS) hazard ratio (HR) 7.83, 95%CI 0.82-74.48; p=0.0002] and poorer melanoma-specific survival (MSS) [HR 6.35, 95% CI 0.36-110.70; p=0.0337]. Conclusions: Post-surgery ctDNA positivity can signal imminent recurrence, thus offering a window for personalised adjuvant therapy modification.

Outcomes of Near-Total and Subtotal Resection of Sporadic Vestibular Schwannoma: A Systematic Review and Meta-Analysis.

To evaluate tumor control and facial nerve outcomes after gross-total (GTR), near-total (NTR), and subtotal resection (STR) of sporadic vestibular schwannomas (VS). PubMed, Cochrane Central Register of Controlled Trials, Web of Science, and Scopus databases were searched in August 2021 through inception following PRISMA guidelines. English language articles reporting tumor control and facial nerve outcomes of adults (≥18 years) with NTR and STR of VS were evaluated. Study characteristics, demographics data, tumor characteristics, type of surgical intervention, and outcome measures on tumor control and facial nerve function were collected. Pooled relative risk (RR) estimates for tumor recurrence and facial nerve outcomes were calculated and stratified by extent of resection. From an initial search of 2504 articles, 48 studies were included in the analysis. When comparing 1108 patients who underwent NTR to 3349 patients with GTR, the pooled RR of recurrence in the NTR cohort was 2.94 (95% confidence interval [CI] 1.65-5.24, P = .0002). When comparing 1016 patients who underwent STR to 6171 patients with GTR, the pooled RR of recurrence in the STR cohort was 11.50 (95% CI 6.64-19.92, P < .0001). Estimates for risk of tumor regrowth for less-than-complete resection are presented. There was no elevated risk of adverse facial nerve outcome (defined as House-Brackmann grade III and above) in each category of extent of resection compared to GTR. Extent of resection predicts risk of tumor recurrence/regrowth following microsurgical resection. Favorable facial nerve outcome should be weighed against the increased risk of regrowth and the potential need for further treatment.

Living with an artificial eye: qualitative insights into patient and family member experiences.

Artificial eye users (AEUs) can experience a negative impact on psychological and emotional wellbeing, including reduced social functioning, which may be a consequence of living with one eye removed, and/or of having a prosthetic eye. This may have wider consequences for their families. We aimed to explore what it means to live with a prosthetic eye, for both AEUs and their families-and how any quality of life (QoL) issues impact on their day-to-day functioning. A subset of AEUs and their family members taking part in a feasibility randomised controlled trial comparing hand-painted to digitally printed artificial eyes were invited for semi-structured interviews. Transcripts were analysed using reflexive thematic analysis. Qualitative results related to trial participation are covered elsewhere. Here, we focus on QoL and day-to-day functioning. Twelve AEUs (eight males) and five spouses (one male) who had worn artificial eyes for 2-65years took part, and four themes were identified. (1) Impact on day-to-day life: AEUs and their spouses have to adapt to (partial) sight loss, reduced levels of confidence, and social withdrawal. (2) Impact on psychological and emotional wellbeing: distress among AEUs and their spouses can be severe and prolonged, highlight unmet support needs. (3) Challenges with treatment experiences: AEUs experienced negative impact of fragmentation of care and long waiting times. (4) Worries about the future: AEUs mentioned fragility of remaining sight, and concerns around potential need for further treatment. Patients and their family members experience negative impact of being an AEU on their everyday lives and quality of life. There is a potential role for psychosocial support services in supporting AEUs and their families even long after eye loss.

Assessment of three different approaches for integrating phosphorus recovery from sewage sludge and derived products in existing wastewater treatment plants

Three different technological solutions, namely acidogenic fermentation and chemical extraction (alkaline or acidic), followed by precipitation with 1% Ca(OH)2, were investigated in the view of integrating phosphorus recovery into existing wastewater treatment plants. Experiments were conducted at the lab-scale using (i) sludge taken from biologically and chemically promoted phosphorus removal activated sludge processes and (ii) ashes obtained from sludge muffle incineration. Results highlighted the benefits of enhanced biological phosphorus removal (EBPR) systems rather than chemically promoted phosphorus removal in not only phosphorus extraction (up to 40% with EBPR) and recovery directly from secondary sludge (P precipitation between 66 and 92%), but after sludge incineration as well (P extraction up to 96% and precipitation above 96%). Acidogenic fermentation ensured the highest phosphorus release from EBPR sludge (equal to a concentration in solution of 122 mg/L P-PO43−), while the derived ashes had a lower level of metal contamination (particularly Fe and Al content < 2%). The phosphorus-rich product obtained by means of the recovery process showed relevant metal contamination (Cu, Zn, and Ni) under some operating conditions, suggesting the need for further treatments.

Reaching the limits of antipsychotic treatment: the upper end of severe schizophrenia in forensic institutions - a case report

IntroductionSevere schizophrenia is often closely related to delinquency resulting in relative overrepresentation of these manifestations of disease in forensic institutions.ObjectivesThe aim of the present work is to report the therapeutic challenges in a case of severe schizophrenia in a forensic institution from a clinical viewpoint as a basis for discussion.MethodsThe case report is based on the available clinical documentation, exploratory interviews as well as a structured clinical interview (PANSS).ResultsPresenting a case of a 41-year-old, male Caucasian inpatient suffering from a catatonic schizophrenia, we report the challenges in treatment of chronic, major schizophrenic disease resistant to antipsychotic medication. Without any previous criminal convictions, he has been instutionalized in a forensic psychiatry after a bodily harm to a random stranger about three years ago. Regarding medical history, information is limited to a few inpatient admissions prior to detention documenting intravenous opioid and cocaine abuse. Initially, the patient presented sexual disinhibition and ongoing endangerment of others with frequent assaults to other patients and prison guards. From a psychopathological viewpoint several phenomenona such as delusional intuition, acoustic, tactile and coenaesthetic hallucinations, echolalia, mannerisms and thought diffusions reflect the severe course of the disease (PANSS: P 34/49, N 38/49, G 73/112; total 145/210). Therapeutic attempts with an antipsychotic combination of risperidone, olanzapine and quetiapine as well as valproic acid resulted in insufficient recovery with persistent physical assaults and florid psychosis. In reaction to that zuclopenthixol for impulse control was added. As from the beginning of this year a switch of medication by gradually replacing risperidone and zuclopenthixol with haloperidol and clozapine showed modest success. Under the current medication and therapeutic drug levels the patient does not pose endangerment to others. However, regular tonic-eye fits require supplementary treatment with biperiden, and the patient still presents frequent periods of self-harm punching himself, verbal lack of impulse control and the psychopathological phenomenona described before. In addition to pharmacological treatment the patient receives psychotherapeutic one-on-one conversations. Despite approaching all limits of the available antipsychotic repertoire, psychopathology is only insufficiently controlled leading considerations to electroconvulsive therapy as a treatment of last resort.ConclusionsCertainly, the present case is exemplary for a severely ill population of patients reaching – after a long and untreated course of disease - a chronic stage that does not sufficiently respond to a multitude of treatment attempts despite proper compliance raising the urgent need for further treatment options.Disclosure of InterestNone Declared

Clinical, radiographic and histological findings of seven teeth from two California sea lions (Zalophus californianus) housed under professional care.

Seven teeth extracted from two adult California sea lions (Zalophus californianus) due to pulp exposure and/or to gain access to the mandibular canine teeth were histologically evaluated, and the findings were compared with clinical and radiographic findings. Three teeth were diagnosed with pulp exposure, and two of these showed no radiographic signs of endodontic disease and were histologically vital with prominent coronal pulpitis and a pulp polyp. Another tooth with pulp exposure was showing clinical and radiographic signs of endodontic disease and was histologically confirmed with pulp necrosis. A discoloured incisor tooth was showing radiographic signs of endodontic disease and was also histologically non-vital. Two clinically and radiographically healthy mandibular first premolar teeth and one second incisor tooth had no evidence of pulpitis or pulp necrosis but had pulp canal obliteration. Regular clinical and radiographic follow-up for 5 months to 3 years after the procedures confirmed uneventful healing of the extraction sites, despite initial flap's dehiscence. Although extractions of affected teeth in California sea lions are considered the most practical and beneficial therapy, these are associated with the risks of extensive trauma and anaesthesia and the need to perform these surgical procedures on-site under variable conditions. As California sea lions can be trained to allow conscious dental radiographic re-checks, monitoring teeth with clinical signs of pulp polyp formation and without radiographic signs of endodontic disease warrant further evaluation/reconsideration from previous recommendations. Endodontic treatment of abscessed teeth in California sea lions is reportedly unsuccessful and is discouraged. However, vital pulpectomy could be an alternative treatment to extraction in teeth with pulp polyps as it was found to be highly successful in humans, but the possibility of endodontic failure and need for further treatments should be weighted in the treatment choice.

Innovative electrocoagulation strategies for landfill leachate treatment: Comparative analysis of aluminum and iron electrodes

ABSTRACT This study investigates landfill leachate treatment using aluminum (Al-Al) and iron (Fe-Fe) electrodes in electrocoagulation (EC). Aluminum experiments revealed COD removal percentages of 22% (pH 7.4) and 20% (pH 6.0), while iron demonstrated higher efficiency at 32% (pH 7.4) and 30% (pH 6.0). Both processes excelled at neutral pH, with Fe-Fe EC displaying superior removal efficiency. To address electrode passivation, external aeration improved COD removal (31% to 61%) under specific conditions (3 V, pH 7.4, 60 min). The EC process established a neutralization mechanism, eliminating the need for further treatment before discharge. External aeration and polarity changes at intervals mitigated passivation, enhancing COD removal (61% to 69%). Voltage testing (1 V, 3 V, 5 V, 7 V) revealed a direct correlation, peaking at 91% efficiency with 5 V. Specific energy consumption was 2.34 kWh g−1, and sludge generation varied with voltage. The combined use of external aeration and polarity shifts resulted in 270 ml of sludge, demonstrating improved efficiency in the EC process.

Uses of nerve block in shoulder dislocation in emergency department - a systematic review

Background: Nerve block is a potentially helpful localized analgesic technique for reducing shoulder dislocation and humorous fractures in the emergency room. Examining the usefulness of NB pain reduction, adverse events, patient satisfaction, and LOS in the ED is the objective of this systematic review. Method: We conducted an electronic search of EMBASE, MEDLINE, and the Cochrane Library in addition to a manual search of the references, included articles were RCTs published between 2002 to 2022 comparing PSA with NBs for orthopedic reductions in the ED. Interest grabbing outcomes were pain ratings, adverse events, LOS in the ED, and patient satisfaction. Results: Six studies were included in the final analysis. Consequently, 256 patients from 6 RCTs were included; 127 of them underwent PSA and 129 NB. When comparing the PSA group to the NB group, the PSA group reported adverse events more frequently. The NB group only experienced a transient systemic toxicity that resolved on its own without the need for further treatment or intervention. Hypoventilation with decreased saturation of oxygen was the most frequent adverse event seen in the patient underwent PSA. Regarding LOS all studies showed shorter LOS in patients underwent NB. Conclusion: We found no appreciable difference in pain ratings for ED fracture or dislocation reductions between PSAs and NBs in this thorough investigation. NBs appear to be associated with a shorter duration of stay and fewer unfavorable events in the ED.

The Impact of Orthodontic Treatment on Teeth Previously Treated with Regenerative Endodontics: A Systematic Review

Objective: To assess the tooth survival rates, adverse events, and need for further treatment of teeth previously treated with regenerative endodontics undergoing orthodontic treatment. Material and Methods: A literature search was performed using MEDLINE, EMBASE, Cochrane, Scopus, and Lilacs databases, grey literature, and endodontic journals, and the date of the last search was 20 April 2022. The included studies involved patients undergoing orthodontic treatment and at least one tooth that was previously treated with regenerative endodontics. A narrative synthesis of the findings was made. The risk of bias and evidence quality were assessed using the Effective Public Health Practice Project tool and the GRADE approach. Results: Five case reports included seven patients and eight teeth with a follow-up of 4 to 11 years. The overall risk of bias was high, and the certainty of evidence was very low. The survival rate was 87.5%. Adverse effects included sinus tracts, root resorption, symptomatology, apical periodontitis, and intracanal tissue necrosis. Five out of eight teeth required further intervention after orthodontics. Conclusions: A high prevalence of adverse effects and further intervention is observed in teeth treated with regenerative endodontics undergoing orthodontic treatment. The low quality of evidence highlights the need for comparative studies and evidence-based guidelines for managing these teeth during orthodontic treatment.

Incidental findings in cone beam computed tomography (CBCT) scans for implant treatment planning: a retrospective study of 404 CBCT scans

ObjectivesTo investigate the prevalence of incidental findings and need for further dental treatment and analyse the influence of size of field-of-view (FOV) and age in cone beam computed tomography (CBCT) for pre-implant planning.Methods404 CBCT scans were examined retrospectively for incidental findings and need for further dental treatment. Incidental finding-frequencies and need for further treatment were assessed for different age (< 40 years, 40–60 years, > 60 years) and FOV groups (small, medium, large). Intraexaminer and interexaminer agreements were evaluated.ResultsIn 82% of the scans at least one incidental finding was found, with a total of 766 overall. More incidental findings were found in scans with large FOV (98% vs. 72%, OR = 22.39 large vs. small FOV, p < 0.0001) and in scans of patients > 60 years (OR = 5.37 patient’s age > 60 years vs. < 40 years, p = 0.0003). Further dental treatment due to incidental findings was needed in 31%. Scans with large FOV were more likely to entail further treatment (OR = 3.55 large vs. small FOV, p < 0.0001). Partial edentulism and large FOV were identified as risk factors for further treatment (p = 0.0003 and p < 0.0001). Further referral of the patient based on incidental findings was judged as indicated in 5%. Intra- and inter-examiner agreements were excellent (kappa = 0.944/0.805).ConclusionsA considerable number of incidental findings with need for further dental treatment was found in partially edentulous patients and in patients > 60 years. In pre-implant planning of elderly patients, the selection of large FOV CBCT scans, including dentoalveolar regions not X-rayed recently, help to detect therapeutically relevant incidental findings.

General dental practitioners' fees for root canal treatment, coronal restorationand follow-on treatment in the adult population in Sweden: A 10-year follow-up of data from the Swedish Dental Register.

To analyze the accumulated fees connected with root filling, permanent coronal restoration and follow-on treatment charged by Swedish dentists over a 10-11-year follow-up period. Furthermore, analyzing these fees with reference to the type of restoration, tooth group, and the root-filled teeth which survived compared to those requiring extraction. In 2009, the data register of the Swedish Social Insurance Agency recorded a total of 215,611 teeth as root-filled. The accumulated fees for each tooth encompassed the following interventions: initial root filling, coronal restorations, and follow-up treatments during the designated period. The outcomes were analyzed using descriptive and analytic statistics, including ttests and one-way analysis of variance. The fees are presented in Euros (€1 = SEK 8.94). The total accumulated fees for root fillings amounted to 72 million Euros: the mean fee per root filled tooth was €333.6. The total mean fee over a 10-11-year period, comprising root canal treatment, coronal restorations, and any follow-up treatments, was €923.4. Root-filled teeth with indirect restorations presented a higher mean fee (€1 279.3) compared to those with direct restorations (€829.4) or those without specified restorations (€832.7; p < .001). Moreover, molars presented a significantly higher mean fee (€966.4) compared to premolars (€882.8) and anterior teeth (€891.3; p < .001). Lastly, the mean fee for extracted teeth was €1225.3, which was higher compared to those who survived the follow-up period (€848.0; p < .001). Fees charged by general dental practitioners for root-filled teeth accumulate over time, probably due to the need for further treatment of the tooth. The total mean fee was significantly higher for molars and root-filled teeth with indirect restorations. However, an analysis of the total costs would require prospective clinical cost-effectiveness studies.

Promise: Investigation into the Combination of a Potent Beti with Ruxolitinib in Patients with High or Intermediate-2 Risk Myelofibrosis Not Receiving an Adequate Response with Ruxolitinib Alone

ISRCTN: 12451433 Background: Myelofibrosis (MF), a chronic myeloproliferative neoplasm (MPN), often results in progressive splenomegaly and cytopenia (1). Acute myeloid leukaemia develops in 10-20% of patients, and median survival with intermediate-2 disease is four years (2). Stem cell transplant can be curative, but is only suitable for younger, comorbidity-free patients (median MF diagnosis is 73.6 years) (3). Janus Kinase 2 (JAK2) mutation is common in MPN, and the JAK1/2 inhibitor ruxolitinib was approved in 2011 (4). However, patients still experience high disease burden, with a clear need for further treatments. Research has now focused on bromodomain and extra terminal (BET) inhibitors (5), in particular the role these have in disease associated inflammation (6). Preclinical data suggests BETi disrupts this inflammation leading to anti-fibrotic activity within MPN models. BETi with ruxolitinib eliminates fibrosis in MF mouse models thus overcoming a limitation of ruxolitinib monotherapy (7). OPN-2853 (previously PLX2853) is potent against isolated bromodomains from multiple BET proteins with rapid drug absorption, high Cmax, and short half-life differentiating it from other BETi. Preclinical efficacy has been demonstrated across a range of hematologic malignancies. PROMise is evaluating OPN-2853 in combination with ruxolitinib to identify the recommended phase 2 dose (RP2D). Methods: Primary Objectives: To assess the RP2D of OPN-2853 in combination with ruxolitinib that is safe and tolerableTo assess the efficacy of the combination of OPN-2853 and ruxolitinib for reduction in spleen size PROMise is a single country (UK) multicentre study, recruiting up to 60 patients with high or intermediate-2 risk MF who are not receiving an adequate response on ruxolitinib alone. Patients must have been treated with ruxolitinib for at least 24 weeks, on a stable dose for at least 4 weeks, and have ongoing splenomegaly. PROMise is split into three ruxolitinib dose categories based on platelet count which are assessed independently, Low Dose (5mg-20mg daily), Mid Dose (25mg-45mg daily) and High Dose (≥50mg daily). These are evaluated in combination with three OPN-2853 dose levels, Level 1 (20mg OD Decreased Dose), Level 2 (40mg OD Starting Dose) and Level 3 (80mg OD Increased Dose). Cohorts of patients (n=2-4) receive up to eight 21-day cycles of OPN-2853 and ruxolitinib. Patients are closely monitored for Dose Limiting Toxicities in cycle 1. The Trial Safety Committee (TSC) meets following cycle 1 to establish the dose recommendations of OPN-2853 for each dose category using the continual reassessment method (CRM). The CRM is utilised independently for each dose category, as such it is possible for the low, mid and high doses to be allocated to different OPN-2853 doses. Following cycle 8, patients may continue to receive OPN-2853 if experiencing clinical benefit and are followed up annually. Peripheral blood, bone marrow aspirate and bone marrow trephine samples are taken from all patients to measure the proportion who achieve a molecular response, and to determine the on target transcriptional response in myeloid cells. Additionally, pharmacokinetic samples are taken at specified timepoints pre and post dose to establish PK properties of OPN-2853 in combination with ruxolitinib. Current Status: To date PROMise has recruited 14 patients across all dose categories, and two TSC meetings have taken place.

Equine dental sinusitis—A statistical analysis of the effect of antibiotics on dental sinusitis following dental extraction

SummaryBackgroundAntibiotic resistance is an increasing global threat to human and veterinary practices. The relevance and efficacy of antibiotic therapy in the treatment of various diseases has been poorly documented in the literature. One such disease is equine sinusitis secondary to dental disease where dental extraction is most often combined with broad‐spectrum antibiotic treatment. It, however, remains undocumented if antibiotic treatment reduces the risk of complication in horses where the diseased tooth is removed by extraction.ObjectivesThe aim of this study was to analyse the effects of perioperative antibiotics in horses with dental sinusitis treated by dental extraction with or without concurrent antibiotic treatment.Study designRetrospective cohort study.MethodsClinical records from horses presenting with nasal discharge between September 2016 and May 2022 were reviewed. Horses with sinusitis secondary to dental disease were identified, and data from clinical records were collected supplemented by online questionnaires. The final statistical model was built using logistic regression.ResultsA total of 59 horses with dental sinusitis were included in the study. Following dental extraction, 62.5% (15/24) of horses that did receive perioperative antibiotics and 60% (21/35) of horses that did not receive perioperative antibiotics were successfully treated without the need for further treatment. The final model showed no significant difference on the probability of success (p = 0.85) between treatment with and without antibiotics.Main limitationsThe retrospective nature of this study may increase the risk of biases in relation to data collection and follow‐up information and the limited number of individuals available for the analysis.ConclusionsThese findings indicate that the use of perioperative antibiotics does not influence the likelihood of complications or the probability of a successful outcome in horses with dental sinusitis undergoing dental extraction.

Factors that influence parental satisfaction with SDF treatment in healthy children and those with special healthcare needs

PurposeSilver diamine fluoride (SDF) is used as a caries management agent for the arrest of dentinal caries lesions. The purpose of this study was to evaluate the satisfaction with SDF treatment provided at a university pediatric dentistry clinic and to identify factors that may contribute to parental dissatisfaction.MethodsWe obtained retrospective data of children who received SDF treatment at our clinic from 1 February 2019 to 28 February 2021. Parents were contacted by phone to participate in a survey that evaluated their satisfaction with the treatment. Satisfaction was evaluated as a function of medical status, ease of treatment, outcome of SDF treatment, esthetics, and understanding of treatment goals and side effects using contingency tables and chi-square statistics.ResultsFrom 209 children who received SDF treatment, we were able to contact 91 parents by telephone, and 79 agreed to participate. Special healthcare needs (SHCN) patients were overrepresented in our sample, comprising 22.3% of all treated and 36.7% of participants. More than 90% were satisfied with the treatment, would do it again and would recommend it to others. Among the 49 children who complained of pain, SDF treatment resolved 82% of these complaints. In the subsample with follow-up in our clinic, approximately half of the treated teeth later received restorative treatment or were extracted, and the other half presented without further treatment. Some children received further treatment elsewhere. Parental dissatisfaction was related to staining of the anterior teeth (p = 0.04), the need for further treatment (p = 0.02) and a lesser understanding of side effects (p = 0.002).ConclusionMost parents were satisfied with SDF therapy as a dental treatment choice due to its easy application and desensitizing effects. Our findings indicate that parental understanding of the interim nature of the treatment and staining of the lesions is important to achieve parental satisfaction.

Analysis of the Potential for Reusing Sanitary Effluents in the Hydrographic Basin of the Ipojuca River

Objective: This study aims to present an assessment of the potential for reusing effluents from domestic sewage treatment plants in the Hydrographic Basin of the Ipojuca River. Theoretical Framework: In regions facing water scarcity, effluent reuse emerges as an alternative to alleviate pressures and reduce contamination of water sources. In this regard, the choice of the Ipojuca River Watershed is justified due to the susceptibility of its constituent municipalities to water scarcity and pollution, as well as the fact that the Ipojuca River has been classified as the third most polluted in the country. Methodology: The methodology involved basin characterization, data collection from the sanitation services provider to perform quantitative and qualitative evaluation of reclaimed water supply, identification of demands based on consumptive uses (industry and irrigation), existing water use permits, and the provider's customer database. Additionally, georeferenced maps were generated for spatial analysis of the water balance. Results and Conclusion: Twelve Sewage Treatment Plants were identified, four of which are still under construction, with nominal treatment capacities exceeding the identified irrigation and industrial demands, except for two of them. In terms of quality, for the analyzed parameters, the treatment plants demonstrated satisfactory performance, suggesting that the effluent could be utilized for restricted purposes without the need for further treatment. Lastly, geospatially, the demands are located within a radius of 10km from the analyzed plants, in most cases. Research Implications: It can be inferred that the basin holds a significant reuse potential to be explored as an alternative for enhancing water availability and reducing effluent discharge into the Ipojuca River. Originality/Value: The results obtained through this unprecedented analysis in the watershed serve as a reference for policymakers and implementers of water resources management policies, as well as an encouragement for potential producers and consumers of reclaimed water.
