Masticatory function between chewing with and without wearing clear thermoplastic appliances

BackgroundClear thermoplastic materials are used in a variety of oral appliances. In some situations, patients may wear clear thermoplastic appliances while eating. However, the effect of wearing clear thermoplastic appliances on chewing efficiency is unknown. This study aimed to evaluate the differences in masticatory function between chewing with and without wearing clear thermoplastic retainers over a 6-month period, and its associated factors.MethodsThirty patients who received upper and lower clear retainers after debonding fixed appliances were examined for objective and subjective masticatory function at retainer delivery (T0), 3-month (T1), and 6-month follow-ups (T2) in two conditions: with and without wearing their retainers while chewing. The objective method used multiple sieves reported as the median particle size (MPS). The food intake ability (FIA) test served as the subjective method. Paired t-test was used to compare the outcomes between chewing with and without retainers at each evaluation time point. Repeated measures ANOVA followed by the Bonferroni post-hoc test was used to compare the outcomes between the three evaluating time points. Multivariable linear regression analysis was performed to assess whether age, sex, and extraction/non-extraction was associated with these effects.ResultsThe MPS was significantly greater when chewing with retainers compared with chewing without them at T0 (P < 0.05), however, it was not significantly greater at T1 and T2 (P > 0.05). The MPS with and without the retainers tend to decrease between T0, T1 and T2. In particular, the MPS while chewing with retainers significantly decreased between T0 and T1. The total FIA score and FIA subscores for hard and soft food were significantly lower when eating with retainers at T0 (P < 0.05), however, all FIA scores when eating without retainers did not significantly change between T0, T1, and T2. No significantly associated factors were identified.ConclusionsWearing clear retainers while chewing decreases objective and subjective masticatory function immediately after completing orthodontic treatment. However, this significantly improved to levels comparable to chewing without retainers after a 3-month follow-up. Age, sex, and extraction/non-extraction treatment were not associated with the difference in masticatory function while chewing with and without wearing the retainers.

Strategic Dual Approach for the Management of a Symptomatic Giant Partially Thrombosed Aneurysm at the Basilar Tip - Integrating Intrasaccular Flow Diversion and Endovascular Flow Reversal.

Managing giant partially thrombosed intracranial aneurysms presents significant challenges due to their unfavorable natural history and the lack of standardized treatment approaches. Conventional treatments, whether open surgical or endovascular, often struggle to manage these aneurysms effectively, resulting in high recurrence rates or significant morbidity. The patient was a 62-year-old male with a symptomatic giant partially thrombosed aneurysm at the tip of the basilar artery, presenting with left-sided hemiparesis and dysarthria. Diagnostic imaging revealed a giant aneurysm with a wide-necked, canalized portion. A two-stage endovascular treatment was conducted, involving a balloon occlusion test (BOT) and intraoperative monitoring (IOM) for maximum patient safety. The treatment utilized stent-assisted Woven EndoBridge (WEB) embolization and serial bilateral vertebral artery trapping. The procedure successfully isolated the aneurysm and postoperative imaging confirmed the absence of recanalization, preserving the intact posterior circulation. The patient showed stable recovery and no neurological deficits during the 12-month follow-up period. This technical note demonstrates the feasibility and efficacy of strategically integrating intrasaccular flow diversion using a WEB device and flow reversal through bilateral vertebral artery trapping for treating giant partially thrombosed aneurysms.

A Retrospective Claims Analysis of the Rate of Complications in Patients Undergoing Treatment for Paroxysmal Nocturnal Hemoglobinuria.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare blood disease associated with complications that increase morbidity, such as thrombosis and chronic kidney disease. Limited data exist regarding complications among treated patients outside of clinical trials, especially for patients treated with ravulizumab. This study leverages MarketScan claims data to examine the rate of complications in patients receiving PNH treatment. Patients with a diagnosis code of PNH [International Statistical Classification of Diseases and Related Health Problems (ICD-10) diagnosis code: D59.5] between October 2015 and December 2020, aged≥18 on the date of diagnosis, who had a≥6-month follow-up period of continuous enrollment and≥1 PNH-indicated treatment on or after the first PNH diagnosis were included. Among 211 patients diagnosed with PNH being treated with eculizumab or ravulizumab between October 2015 and December 2020, the most common complications were iron deficiency (20.4% of patients), arterial embolism and thrombosis (16.1%), and chronic kidney disease (11.8%). Overall, 44.1% of patients experienced≥1 complication. The high number of patients with PNH receiving treatment who nevertheless experienced complications demonstrates significant unmet medical need. Further analysis with larger sample sizes and including newer therapies, such as pegcetacoplan and iptacopan, is required to fully understand the scope and magnitude of this unmet need.

A Five-Bundle Intervention to Improve Blood Culture Use in a Tertiary Hospital in Romania

Objectives: The aims of this study were to evaluate the efficacy of a five-bundle intervention and to decrease the number of cases in which only one set of blood cultures is collected prior to starting antimicrobials. Methods: The study group consisted of the two hospital wards that have the highest collection rate (120 blood cultures/1000 patient days and 121.4 blood cultures/1000 patient days, respectively), and the control group consisted of the other three adult wards. The collection protocol was changed, and a bundle of five measures was introduced: one-on-one discussions with the nurses, 2% chlorhexidine in 70% alcohol for disinfection, ensuring the use of sterile gloves, sterile wipes, a checklist for the materials needed, and a copy of the collection protocol. The impact of these changes was followed over a 5-month period. Results: Prior to the intervention, the contamination rate was higher in the control group (6.5%) versus the study group (4%), p = 0.00578. The before–after analysis revealed a significantly reduced contamination rate in the control group (4.6% vs. 6.5% p = 0.0099), but it was above the one obtained in the study group (3.1% vs. 4%, p = 0.1635). The number of infectious episodes in which one blood culture set was collected decreased significantly in the study group (77/311 vs. 139/456, p = 0.041). Conclusions: The intervention decreased the contamination rate and the number of infectious episodes in which one blood culture set is collected.

Cancer-Related Cognitive Impairment: A Survey of Speech-Language Pathologists' Knowledge, Training, and Attitudes

Purpose: This study examined speech-language pathologists' (SLPs') professional knowledge, training experiences, and attitudes in assessing and treating individuals with cancer-related cognitive impairments (CRCIs). Understanding these concepts is necessary for evaluating SLPs' role in supporting individuals with CRCIs. Method: A web-based survey was completed by 147 SLPs over a 2-month period. The survey explored their professional knowledge, training, and attitudes regarding CRCI assessment and intervention. Results: Three quarters of participants reported some experience with individuals with CRCIs. Most participants reported that providing care for individuals with CRCIs was within the SLP scope of practice (97%) and an ethical responsibility (93%). Approximately 65% of participants completed some form of training for providing services for this population; 98% would pursue diagnostic training in the future, and 66% would pursue intervention training in the future. Regarding attitudes, 80% of participants shared that they were comfortable with the idea of providing cognitive-communication services to individuals with CRCIs, and almost all (97%) felt that cognitive-communication services were a medical necessity for this population. Additional analyses were conducted to assess the effect of years of experience on various aspects of professional knowledge and attitudes. Conclusions: SLPs were trained to assess and treat the cognitive-communication domains impacted by CRCIs. Recommendations for meeting this need are also discussed. Further research regarding the role of SLPs in the assessment and treatment of CRCIs is warranted.

Body Positivity, Physical Health, and Emotional Well-Being Discourse on Social Media: Content Analysis of Lizzo's Instagram.

Weight stigma is a fundamental cause of health inequality. Body positivity may be a counterbalance to weight stigma. Social media is replete with weight-stigmatizing content and is a driver of poor mental health outcomes; however, there remains a gap in understanding its potential to mitigate the prevalence and impact of harmful messaging and to promote positive effects on a large scale. We selected musical artist Lizzo, whose brand emphasizes body positivity and empowerment, for an instrumental case study on the discourse on social media and specifically Instagram. We focused on 3 domains, including body positivity, physical health, and emotional well-being. These domains challenge social norms around weight and body size and have the potential to positively affect the physical and psychological health of people with diverse body sizes. We evaluated posts by Lizzo, comments from Instagram users, and replies to comments over a 2-month period (October 11 to December 12, 2019). Two coders rated Lizzo's posts and Instagram users' comments for their sentiments on the 3 domains. Replies to Instagram users' comments were assessed for their reactions to comments (ie, did they oppose or argue against the comment or did they support or bolster the comment). Engagement metrics, including the number of "likes," were also collected. The final sample included 50 original posts by Lizzo, 250 comments from Instagram users, and 1099 replies to comments. A proportion of Lizzo's content included body positive sentiments (34%) and emotional well-being (18%); no posts dealt explicitly with physical health. A substantial amount Instagram users' comments and replies contained stigmatizing content including the use of nauseated and vomiting emojis, implications that Lizzo's body was shameful and should be hidden away, accusations that she was promoting obesity, and impeachments of Lizzo's health. In spite of the stigmatizing content, we also discovered content highlighting the beneficial nature of having positive representation of a Black woman living in a larger body who is thriving. Moreover, analysis of the discourse between users illustrated that stigmatizing expressions are being combated online, at least to some degree. This study demonstrates that Lizzo has exposed millions of social media users to messages about body positivity and provided more visibility for conversations about weight and shape. Future research should examine the extent to which body positive messages can lead to greater acceptance of individuals living in larger bodies. Instagram and other social media platforms should consider ways to reduce body-shaming content while finding ways to promote content that features diverse bodies. Shifting the landscape of social media could decrease stereotypes about weight and shape while increasing dialog about the need for greater acceptance and inclusion of people with diverse bodies.

First-Time Successful Trial Without Catheter (TWOC) After GreenLight Laser Photoselective Vaporization of the Prostate (GLL PVP) Surgery for an Enlarged Prostate.

Objective We aimed to assess the success rate of the GreenLight laser photoselective vaporization of the prostate (GLL PVP) procedure for enlarged prostates in patients with and without preoperative long-term catheters. Methodology A retrospective data analysis was conducted on 46 patients. Data were collected from clinical health records and radiology images. The parameters studied in this analysis included the patient's age, prostate volume, medical management before surgery, and whether the patient had a catheter or not prior to the surgery. Results A total of 46 GLL PVP surgeries were performed over a 12-month period from May 2023 to May 2024 at West Middlesex University Hospital in London. Patients had a mean age of 73.2 ± 8.12 years, and their prostate volume was 57.7 ± 25.96 cc. Before the surgery, 14 cases (30%) were using long-term catheters, and 32 cases (70%) were not. Additionally, 40 cases (87%) were receiving medical management for lower urinary tract symptoms (LUTS). After the surgery, 39 cases (85%) passed their first trial without catheter (TWOC), and seven cases (15%) failed it, regardless of whether they had used catheters before the surgery. Patients using long-term catheters before the operation had a 71% success rate in passing their first TWOC and a 29% failure rate. Conclusion Our study found that GLL PVP has a significant positive impact on elderly individuals with a large prostate volume, regardless of whether they had long-term catheters or not prior to the operation. Additionally, our findings indicate that patients without preoperative long-term catheters experience significantly better outcomes.

Sexually Transmitted Infections in Pre-Exposure Prophylaxis Patients

Background: Pre-exposure Prophylaxis (PrEP) has revolutionized HIV prevention, but concerns exist about its potential impact on other Sexually Transmitted Infections (STIs). This study aimed to assess the prevalence and patterns of STIs among PrEP users at a single urban clinic. Methods: We conducted a retrospective analysis of 100 patients on PrEP, evaluating STI diagnoses over a 12-month period. Comprehensive STI screening was performed quarterly, including nucleic acid amplification tests for chlamydia and gonorrhea at multiple anatomical sites, and serological testing for syphilis. Results: Of the 100 participants (mean age 32.5 years, 82% men who have sex with men), 42% were diagnosed with at least one STI during the study period. The most common infections were chlamydia (28%), gonorrhea (18%), and syphilis (8%). Among chlamydia and gonorrhea cases, 60.9% were rectal infections. Fifteen percent of patients experienced multiple STI diagnoses. Factors independently associated with STI diagnosis included age &lt;30 years (OR 2.1, 95% CI: 1.3-3.4), ≥5 sexual partners in the past 6 months (OR 2.8, 95% CI: 1.7-4.6), and inconsistent condom use (OR 1.9, 95% CI: 1.2-3.0). Conclusion: This study demonstrates a high prevalence of STIs among PrEP users, emphasizing the need for comprehensive STI prevention, frequent screening, and prompt treatment in this population. While PrEP effectively prevents HIV transmission, it must be implemented as part of a holistic approach to sexual health to address the risk of other STIs.

ACVECC-Veterinary Committee on Trauma registry report 2020-2021.

To report summative data from the American College of Veterinary Emergency and Critical Care (ACVECC)-Veterinary Committee on Trauma (VetCOT) registry, with further individual evaluation of university and private practices and level I and II Veterinary Trauma Centers (VTCs). Multi-institutional registry data report, January 1, 2020, to December 31, 2021. VTCs identified and verified by ACVECC-VetCOT. Dogs and cats with evidence of trauma. Data were input to a web-based data capture system (REDCap) by data entry personnel trained in registry software use and operational definitions of data variables. Patient data on demographics, trauma type, preadmission care, trauma severity assessment at presentation (modified Glasgow Coma Score and Animal Trauma Triage score), key laboratory parameters, interventions, and outcome were collected. Summary descriptive data for each species are reported. Twenty-two VTCs contributed data to the VetCOT registry during a 24-month period, culminating in a total of 9758 complete trauma case records for dogs and 11734 for cats. Head trauma in dogs and cats was seen at a higher percentage in both university-only VTCs (encompassing both level I and II) (20.1% and 24.1%, respectively) and level I-only VTCs (24.3% and 24.1%, respectively), in comparison to private-only VTCs (encompassing both level I and II) (13.5% and 16.2%, respectively) and individual level II VTCs (14.1% and 18.9%, respectively). Canine and feline surgical procedures were performed at a higher percentage at university VTCs (50% and 40.5%, respectively) compared to private VTCs (39.2% and 28.6%, respectively). Overall survival to discharge for dogs and cats remains high at 93.1% and 83.6%, respectively. The VetCOT registry has continued to show powerful potential in collating a large, multifaceted, international dataset in trauma for both dogs and cats. As published in previous VetCOT registry reports, survival to discharge has remained static across both university and private practice veterinary hospitals; however, further breakdown has identified university and level I VTCs admitting and managing a higher number of head traumas, as well as university VTCs performing a higher proportion of surgical procedures. Data from this registry will continue to aid in the design of clinical trials, prospective observational studies, and translational research, which will improve the understanding and outcome of trauma patients.

Thoughts From the Front Lines: Canadian Perspectives in Adopting and Implementing Recommended Clinical Labels in Preschool Speech-Language Pathology.

Previous literature has proposed barriers to speech-language pathologists (SLPs) using standard clinical labels; however, the perspectives of SLPs have been studied to a lesser extent. This quality improvement project reports on SLPs' perceived barriers and facilitators to using currently recommended clinical labels for preschool communication disorders and identifies next steps to support implementation in one preschool communicative health system. This project aimed to establish the consistent use of clinical labels in one large Canadian preschool speech and language program. After completing a web-based training and a 3-month trial period, 387 SLPs completed an exit survey to share their perceived barriers and facilitators to label use. Qualitative survey data were analyzed using a hybrid codebook inductive/deductive thematic analysis approach. Six themes were identified, which aligned with the diffusion of innovations theory. SLPs identified several facilitators and barriers to using the recommended clinical labels within each theme. Major facilitators included improved communication, better caregiver understanding of children's communication, positive feedback from caregivers, SLPs' increased confidence in sharing labels, and improved access to services for children. Major barriers related to additional time required to share labels, SLPs' perceptions of caregivers' values, SLPs' views surrounding the recommended labels, lack of comfort using some labels, and limited opportunity to practice label use or observe successful label use by others. Contextual barriers continue to impact SLPs' use of the recommended clinical labels. Ongoing collaboration with SLPs and caregivers will be critical for supporting implementation. Further research examining SLPs' perspectives across other clinical settings and geographic areas is needed. https://doi.org/10.23641/asha.27296970.

Supplemental Nutrition Assistance Program Work Requirements and Safety-Net Program Participation

Work requirements are a controversial feature of US safety-net programs, with some policymakers seeking to expand their use. Little is known about the demographic, clinical, and socioeconomic characteristics of individuals most likely to be negatively impacted by work requirements. To examine the association between work requirements and safety-net program enrollment. This cohort study included Medicaid and Supplemental Nutrition Assistance Program (SNAP) enrollees in Connecticut. The impact of SNAP work requirements for able-bodied adults without dependents-the target population-was estimated using a triple-differences research design comparing outcomes before and after the policy (first difference) in affected and exempted towns (second difference) between the targeted population and untargeted parents and caregivers (third difference). SNAP and Medicaid enrollment trends were assessed for a 24-month period, and the characteristics of individuals most likely to lose coverage were examined. Data were collected from August 2015 to April 2018, and data were analyzed from August 2022 to September 2024. The reintroduction of SNAP work requirements in 2016. Proportion of enrollees disenrolled from SNAP and Medicaid. Of 81 888 Medicaid enrollees in Connecticut, 46 872 (57.2%) were female, and the mean (SD) age was 36.6 (7.0) years. Of these, 38 344 were able-bodied adults without dependents, of which 19 172 were exposed to SNAP work requirements, and 43 544 were parents or caregivers exempted from SNAP work requirements. SNAP coverage declined 5.9 percentage points (95% CI, 5.1-6.7), or 25%, following work requirements. There were no statistically significant changes in Medicaid coverage (0.2 percentage points; 95% CI, -1.4 to 1.0). Work requirements disproportionately affected individuals with more chronic illnesses, targeted beneficiaries who were older, and beneficiaries with lower incomes. Individuals with diabetes were 5 percentage points (95% CI, 0.8-9.3), or 91%, likelier to lose SNAP coverage than those with no chronic conditions; older SNAP beneficiaries (aged 40 to 49 years) with multiple comorbidities were 7.3 percentage points (95% CI, 4.3-11.3), or 553%, likelier to disenroll than younger beneficiaries (aged 25 to 29 years) without chronic conditions; and households with the lowest incomes were 18.6 percentage points (95% CI, 11.8-25.4), or 204%, likelier to lose coverage than the highest income SNAP beneficiaries. In this cohort study, SNAP work requirements led to substantial reductions in SNAP coverage, especially for the most clinically and socioeconomically vulnerable. Work requirements had little effect on Medicaid coverage, suggesting they did not lead to sufficient increases in employment to transition beneficiaries off the broader safety net.

Blood pressure variability associated with falls in nursing home residents.

High variations in serially measured blood pressures (BPs) portend a variety of adverse clinical events including dementia, cardiovascular sequelae and frailty. In this study, systolic blood pressure variability (BPV) was examined for its association with fall frequency and time to next fall among older adults living in nursing homes. BP values and falls over time were extracted from medical records of nursing home residents aged ≥65 years over a 10-month period. BPV was measured as the standard deviation of 17 to 20 systolic values, and its correlation with falls and time to next fall were evaluated according to quartile values. One hundred patient charts were analyzed with nearly 2000 BP data points. All older adults had at least one fall incident. Higher BPV was related to more falls, shorter time between the first and second fall and fewer average days between falls. Subgroups of high BP and different diagnoses affected this association between BPV and falls. People who fall often show a high variability in BP; as the number of falls increases, the BPV also increases. This study suggests that BPV may be marker for patients who might benefit from more aggressive application of fall reduction strategies. Geriatr Gerontol Int 2024; ••: ••-••.

When Bell's Palsy Is Cancer: Avoiding Misdiagnosis and Its Implications.

Facial paralysis due to cancer can be misdiagnosed as Bell's palsy. This study aims to clearly identify and quantify diagnostic differentiators and further evaluate the prognostic implications of misdiagnosis. Adult patients older than 18 years with facial palsy of unknown or cancerous etiology presenting between 2009 and 2023 were reviewed. Patient characteristics, examination findings, and clinical course were compared between facial paralysis patients with cancer misdiagnosed as Bell's palsy (Cancer-Bell's-Palsy group) and patients correctly diagnosed with Bell's palsy (Bell's-Palsy group). Additionally, morbidity and mortality were compared between facial paralysis patients with cancer initially misdiagnosed with Bell's palsy and facial paralysis patients initially correctly diagnosed with cancer (Cancer-Palsy group). Two-hundred and forty-three patients participated including 43 Cancer-Palsy, 18 Cancer-Bell's-Palsy, and 182 Bell's-Palsy patients. Cancer-Bell's-Palsy patients were significantly less likely than Bell's-Palsy patients to develop synkinesis (odds ratio [OR] = 0.0042; 95% confidence interval [CI]: [0.0005-0.0339]; p < 0.0001), significantly more likely to experience gradual onset facial paralysis (OR = 1,004.69; 95% CI: [54.40-18,555.77]; p < 0.0001), and significantly more likely to have additional nonfacial cranial nerve neuropathies (OR = 49.98; 95% CI: [14.61-170.98]; p < 0.0001). Cancer-Bell's-Palsy patients were more likely than Cancer-Palsy patients to have a greater than 6-month period from initial cancer-attributable symptom onset to cancer diagnosis (OR = 47.62; 95% CI: [9.26-250.00]; p < 0.001), stage IV cancer (OR: 12.36; 95% CI: 1.49-102.71; p = 0.006), and decreased duration of life after cancer diagnosis (median [interquartile range], 40.0 [87.0] vs. 12 [56.3] months, respectively; p = 0.025). Facial paralysis related to cancer must be differentiated from Bell's palsy, as misdiagnosis leads to delayed intervention and poorer prognosis. Gradual onset facial palsy, multiple cranial nerve neuropathies, lack of synkinesis, and lack of improvement were nearly definitive differentiators for underlying cancer.

Monitoring the trade in bat taxidermy and specimens on e-commerce platforms

Wildlife trade is a major economic activity but can pose a threat to many species. Previous research has focused on the trade of bats (Chiroptera) for food and medicine but little is known about the online, international trade in bat taxidermy and specimens, which is thought to be an emerging threat. We aimed to characterise this trade by sampling two major e-commerce platforms over an 18-month period. We used an automated pipeline, whereby data were accessed programmatically; filtered using a neural-network classifier; and the locations and species mentioned in relevant listings were identified using Named Entity Recognition. We retrieved 40,412 relevant results, representing 2363 and 2116 unique listings from Etsy and eBay, respectively. Although the accuracy of listings could not be verified, most (57 %) provided species-level information. Hence, 47 bat species were listed for sale, of which 32 are not currently identified by the IUCN Red List as traded for any purpose. The highest number of listings were sold from USA, Hong Kong and the UK, whilst traded species' ranges were predominantly located in South East Asia. We provide one of the first longitudinal datasets on the online bat trade, indicating that several species are being traded at potentially high volumes, with demand from North America and Europe driving exploitation in South East Asia. This is concerning for highly-traded species which occur at low densities, such as the painted wooly bat Kerivoula picta. Our automated pipeline can be used for subsequent monitoring of this trade, or could be adapted for monitoring of trade in other taxa.

A Multidisciplinary and a Comprehensive Approach to Reducing Fragility Fractures in Preterm Infants.

With advances in neonatal care, bone fractures prior to discharge from the hospital in preterm infants receiving contemporary neonatal care, are rare. Nevertheless, such fractures do occur in very low birth weight and extremely low birth weight infants who go on to develop metabolic bone disease of prematurity (MBDP), with or without secondary hyperparathyroidism. MBDP is a multifactorial disorder arising from the disruption of bone mass accrual due to premature birth, postnatal immobilisation, and loss of placental oestrogen resulting in bone loss, inadequate provision of bone minerals from enteral and parenteral nutrition, and medications that leach out bone minerals from the skeleton. All of these factors lead to skeletal demineralisation and a decrease in bone strength and an increased risk of fractures of the long bones and ribs. Secondary hyperparathyroidism resulting from phosphate supplements, or enteral/parenteral feeds with a calcium-tophosphate ratio of < 1.3:1.0 leads to subperiosteal bone resorption, cortical thinning, and further skeletal weakening. Such fractures may occur from routine handling and procedures such as cannulation. Most fractures are asymptomatic and often come to light incidentally on radiographs performed for other indications. In 2015, we instituted a comprehensive and multidisciplinary Neonatal Bone Health Programme (NBHP), the purpose of which was to reduce fragility fractures in highrisk neonates, by optimising enteral and parenteral nutrition, including maintaining calcium-tophosphate ratio ≥1.3:1, milligram to milligram, biochemical monitoring of MBDP, safe-handling of at-risk neonates, without compromising passive physiotherapy and skin-to-skin contact with parents. The at-risk infants in the programme had radiographs of the torso and limbs at 4 weeks and after 8 weeks from enrolment into the program or before discharge. Following the introduction of the NBHP, the bone fracture incidence reduced from 12.5% to zero over an 18-month period.

Weight Loss and Number of Present Teeth in Community-Dwelling Japanese Older Adults: A Cross-Sectional Study in Niigata.

Weight loss is a critical health issue among the older population. This study aimed to explore the association between weight loss and oral health in older adults. We used cross-sectional data from the Uonuma Chronic Kidney Disease Cohort Study. The binary logistic regression models were fitted to estimate the relationship between weight loss and independent variables including the number of teeth present. The participants included 1656 females and 1625 males. There were 1217 females (73.4%) and 1236 males (76.0%) with normal BMI (18.5 ≤ BMI < 25) in the previous year. Weight loss was determined over a 12-month period. Individuals with normal BMI in previous year, and those with weight loss (≥ 5%) or those whom maintained a stable weight were further analysed. The regression analysis (model 3, fully adjusted) showed that females with 0 and 1-10 teeth present had a higher likelihood of losing weight (OR = 4.07; 95% CI = 1.85-8.93, OR = 2.33; 95% CI = 1.24-4.39) compared with those with 20 or more teeth. Current smokers had a higher likelihood of losing weight (OR = 3.15; 95% CI = 1.01-9.76) than lifelong abstainers. Among males, both current and previous smokers showed a higher likelihood of losing weight (OR = 4.94; 95%CI = 1.76-13.8, OR = 3.35; 95% CI = 1.29-8.68) than those who never smoked. This study indicates that the number of teeth and smoking are both linked to weight loss in females. However, in males, the association between the number of teeth and weight loss may be compromised due to the high prevalence of smoking in this group.

Methodology for Automatically Detecting Pan–Tilt–Zoom CCTV Camera Drift in Advanced Traffic Management System Networks

Many transportation agencies have deployed pan–tilt–zoom (PTZ) closed-circuit television (CCTV) cameras to monitor roadway conditions and coordinate traffic incident management (TIM), particularly in urbanized areas. Pre-programmed “presets” provide the ability to rapidly position a camera on regions of highways. However, camera views occasionally develop systematic deviations from their original presets due to a variety of factors, such as camera change-outs, routine maintenance, drive belt slippage, bracket movements, and even minor vehicle crashes into the camera support structures. Scheduled manual calibration is one way to systematically eliminate these positioning problems, but it is more desirable to develop automated techniques to detect and alert agencies of potential drift. This is particularly useful for agencies with large camera networks, often numbering in the 1000’s. This paper proposes a methodology using the mean Structured Similarity Index Measure (SSIM) to compare images for a current observation to a stored original image with identical PTZ coordinates. Analyzing images using the mean SSIM generates a single value, which is then aggregated every week to generate potential drift alerts. This methodology was applied to 2200 images from 49 cameras over a 12-month period, which generated less than 30 alerts that required manual validation to determine the confirmed drift detection rate. Approximately 57% of those alerts were confirmed to be camera drift. This paper concludes with the limitations of the methodology and future research opportunities to possibly increase alert accuracy in an active deployment.

MACULAR THICKNESS FLUCTUATIONS AND VISUAL ACUITY OUTCOMES AFTER INTRAVITREAL DEXAMETHASONE IMPLANT FOR DIABETIC MACULAR EDEMA.

To assess macular thickness fluctuations and their association with visual acuity outcomes in eyes with diabetic macular edema treated with an intravitreal dexamethasone (DEX) implant. The SD of all postbaseline central subfield thicknesses (CST) recorded over a 12-month period after the first injection of the DEX implant was used to quantify CST fluctuations. Linear regression models were used to identify factors associated with the visual acuity at 12 months (measured with the Early Treatment of Diabetic Retinopathy Study score) and predictors of CST SD. A retrospective review of 80 eyes of 80 patients treated with the DEX implant for diabetic macular edema revealed a CST SD of 75.3 ± 50.3 µ m. The CST SD was negatively associated with the visual acuity at 12 months (-7.7 Early Treatment of Diabetic Retinopathy Study letters for each 100- µ m increase in CST SD, P = 0.01), while changes in CST from baseline did not show any significant association. Eyes were stratified into quartiles based on the CST SD, and a difference by -14.2 letters in visual acuity at 12 months was observed between the first and fourth quartiles ( P <0.001). Significant predictors of CST SD included the baseline visual acuity (-12.0 µ m for each 10-letter increase, P = 0.02) and the number of DEX injections received (n = 17.1, P = 0.03). Greater fluctuations in retinal thickness were found to be associated with poorer visual outcomes in eyes with diabetic macular edema treated with the DEX implant. Analyzing the CST SD could be a more predictive indicator of visual prognosis than individual measurements of the CST.

A Cross-Sectional Study of Unstable Housing and Housing-Related Symptom Content in People With Psychosis Admitted for Inpatient Treatment: A Clinical Record Interactive Search Study.

Rates of psychosis in the homeless population are markedly higher compared to the general population. Understanding potential psychological mechanisms underpinning links between psychosis and homelessness is important for the development of effective care pathways for this highly marginalised group. This study aimed to examine the housing status of a sample of people with psychosis admitted to psychiatric inpatient hospital in one UK mental health trust. We further aimed to examine the presence and relevance of symptoms which were directly related to housing (e.g., persecutory beliefs about neighbours). A cross-sectional study was conducted using an electronic healthcare database, containing anonymised patient records (Clinical Record Interactive Search). Information on housing status, symptoms, and content of symptoms relating to housing were extracted and independently double-coded from clinical notes at the person's admission. 351 service users were in the sample, which covered discharges over a 12-month period (1st April 2021 to 31st March 2022). There was a higher proportion of individuals living without a fixed address in the sample (10%) compared to population estimates (1%-2%). Housing-related thematic content of symptoms was evident in 34% of the sample (e.g., attributing voices to neighbours, feeling under surveillance at home). The only variable significantly associated with housing status was gender, with men at higher odds of unstable housing compared to women. Individuals with concerns directly related to their housing or housing instability were no more likely to have a longer length of admission than those without housing-related concerns. A significant proportion of individuals with psychosis admitted for psychiatric inpatient treatment, experienced housing instability. For some of the sample, symptom content directly related to housing. This raises important considerations for how social needs are assessed on admission to psychiatric hospital. Further research in this area is encouraged.

Comparison of British Thyroid Association and TIRADS classifications and their impact on the radiological and surgical management of indeterminate thyroid nodules

BackgroundThe British Thyroid Association (BTA) Guidelines for the Management of Thyroid Cancer advocate for fine-needle aspiration cytology for all thyroid nodules graded indeterminate (U3) at ultrasound assessment. This approach raises concerns regarding potential over-diagnosis of low-risk lesions. Conversely, equivalent Thyroid Imaging Reporting and Data Systems (TIRADS) guidelines permit surveillance or discharge of indeterminate thyroid nodules of certain sizes. This service analysis analyses how guideline choice impacts the fine-needle aspiration cytology rate and subsequent surgical management of indeterminate thyroid nodules. MethodsAll patients with an indeterminate (U3) thyroid nodule identified on ultrasound over a 12-month period were included. Indeterminate thyroid nodules were retrospectively rescored using three equivalent TIRADS classifications by three independent reviewers, blinded to the histopathology. Hypothetical differences in fine-needle aspiration cytology rates and surgical activity were then compared. ResultsNinety-six nodules were identified. Retrospective application of TIRADS guidelines resulted in a hypothetical 44.8-55.2% reduction in fine-needle aspiration cytology performed for indeterminate thyroid nodules compared to BTA. A statistically significant increase in rates of surgical activity for indeterminate thyroid nodules was observed between BTA guidance and all retrospectively applied TIRADS guidelines (p<0.001). Of four confirmed thyroid cancers, three would have been unanimously removed. ConclusionUnder BTA guidance, increased fine-needle aspiration cytology rates for indeterminate thyroid nodules resulted in significantly increased surgical activity in our cohort compared to retrospectively applied TIRADS guidelines.
