Periodontal therapy for hopeless mandibular anterior teeth: a retrospective case report with a multidisciplinary approach and a 20-year follow-up

Introduction: This case report presents the intentional periodontal maintenance of two periodontal hopeless lower central incisors with a multidisciplinary approach and 20-year follow-up. Case presentation: A 36-year-old male, in 2001, was diagnosed with aggressive periodontitis, gingival swelling, bleeding, and mandibular central incisors with mobility and poor prognosis. Following periodontal therapy (phase I), root canal treatment, and occlusal adjustment, #31 and #41 were gently extracted to remove the granulation tissues, calculus, and infected cementum from the root surface. Then, tetracycline-HCl was applied for 5 minutes on the root surfaces. The teeth were repositioned into the sockets and splinted with a lingual bar. At 3 months, the bar was removed, and a free gingival autogenous graft was done to improve the local keratinized tissue width. Mobility scores, pocket depths, and clinical attachment levels were recorded, and radiographs were taken at 1, 5, and 20 years. The 5-year follow-up showed that the teeth were clinically and radiographically in function. There was a reduction in probing depth and a gain in clinical attachment and radiographic alveolar bone levels. After 20 years, #41 was stable, but #31 had external root resorption, leading to a new treatment plan (dental implants) and extraction. Conclusion: The clinical result of this case was satisfactory for 20 years. Intentional periodontal maintenance of the teeth may be an alternative treatment, even considering the high level of complexity.

Quantitative impacts of meteorology and emissions on the long-term trend of O3 in the Yangtze River Delta (YRD), China from 2015 to 2022.

Extensive spatiotemporal analyses of long-trend surface ozone in the Yangtze River Delta (YRD) region and its meteorology-related and emission-related have not been systematically analyzed. In this study, by using 8-year-long (2015-2022) surface ozone observation data, we attempted to reveal the variation of multiple timescale components using the Kolmogorov-Zurbenko filter, and the effects of meteorology and emissions were quantitatively isolated using multiple linear regression with meteorological variables. The results showed that the short-term, seasonal, and long-term components accounted for daily maximum 8-hr average O3 (O3-8 hr) concentration, 46.4%, 45.9%, and 1.0%, respectively. The meteorological impacts account for an average of 71.8% of O3-8 hr, and the YRD's eastern and northern sections are meteorology-sensitive areas. Based on statistical analysis technology with empirical orthogonal function, the contribution of meteorology, local emission, and transport in the long-term component of O3-8 hr were 0.21%, 0.12%, and 0.6%, respectively. The spatiotemporal analysis indicated that a distinct decreasing spatial pattern could be observed from coastal cities towards the northwest, influenced by the monsoon and synoptic conditions. The central urban agglomeration north and south of the YRD was particularly susceptible to local pollution. Among the cities studied, Shanghai, Anqing, and Xuancheng, located at similar latitudes, were significantly impacted by atmospheric transmission-the contribution of Shanghai, the maximum accounting for 3.6%.

A new method for the rapid identification of external water types in rainwater pipeline networks using UV-Vis absorption spectroscopy.

Ultraviolet-visible (UV-Vis) absorption spectroscopy, due to its high sensitivity and capability for real-time online monitoring, is one of the most promising tools for the rapid identification of external water in rainwater pipe networks. However, difficulties in obtaining actual samples lead to insufficient real samples, and the complex composition of wastewater can affect the accurate traceability analysis of external water in rainwater pipe networks. In this study, a new method for identifying external water in rainwater pipe networks with a small number of samples is proposed. In this method, the Generative Adversarial Network (GAN) algorithm was initially used to generate spectral data from the absorption spectra of water samples; subsequently, the multiplicative scatter correction (MSC) algorithm was applied to process the UV-Vis absorption spectra of different types of water samples; following this, the Variational Mode Decomposition (VMD) algorithm was employed to decompose and recombine the spectra after MSC; and finally, the long short-term memory (LSTM) algorithm was used to establish the identification model between the recombined spectra and the water source types, and to determine the optimal number of decomposed spectra K. The research results show that when the number of decomposed spectra K is 5, the identification accuracy for different sources of domestic sewage, surface water, and industrial wastewater is the highest, with an overall accuracy of 98.81%. Additionally, the performance of this method was validated by mixed water samples (combinations of rainwater and domestic sewage, rainwater and surface water, and rainwater and industrial wastewater). The results indicate that the accuracy of the proposed method in identifying the source of external water in rainwater reaches 98.99%, with detection time within 10 s. Therefore, the proposed method can become a potential approach for rapid identification and traceability analysis of external water in rainwater pipe networks.

A methodological framework for estimating ambient PM2.5 particulate matter concentrations in the UK.

Scientific evidence sustains PM2.5 particles' inhalation may generate harmful impacts on human beings' health; therefore, their monitoring in ambient air is of paramount relevance in terms of public health. Due to the limited number of fixed stations within the air quality monitoring networks, development of methodological frameworks to model ambient air PM2.5 particles is primordial to providing additional information on PM2.5 exposure and its trends. In this sense, this work aims to offer a global easily-applicable tool to estimate ambient air PM2.5 as a function of meteorological conditions using a multivariate analysis. Daily PM2.5 data measured by 84 fixed monitoring stations and meteorological data from ERA5 (ECMWF Reanalysis v5) reanalysis daily based data between 2000 and 2021 across the United Kingdom were attended to develop the suggested approach. Data from January 2017 to December 2020 were employed to build a mathematical expression that related the dependent variable (PM2.5) to predictor ones (sea-level pressure, planetary boundary layer height, temperature, precipitation, wind direction and speed), while 2021 data tested the model. Evaluation indicators evidenced a good performance of model (maximum values of RMSE, MAE and MAPE: 1.80 µg/m3, 3.24 µg/m3, and 20.63%, respectively), compiling the current legislation's requirements for modelling ambient air PM2.5 concentrations. A retrospective analysis of meteorological features allowed estimating ambient air PM2.5 concentrations from 2000 to 2021. The highest PM2.5 concentrations relapsed in the Mid- and Southlands, while Northlands sustained the lowest concentrations.

Long-term treatment results of pembrolizumab monotherapy: reconsideration of immune checkpoint inhibitor monotherapy.

Objective: The extended outcomes of the KEYNOTE-024 study demonstrated a favorable 5-year overall survival (OS) rate of 31.9%. The present study investigated the outcomes of pembrolizumab monotherapy for advanced or recurrent non-small cell lung cancer (NSCLC) at our institution. Patient: The long-term outcomes of 102 patients with advanced or recurrent NSCLC treated with pembrolizumab monotherapy between March 2017 and December 2022 were retrospectively assessed. Results: This study included a total of 102 patients [mean age: 72 ± 9.6 years (range: 41-91 years), male/female=77/25; performance status (PS; 0, 1, 2, 3, 4)=49/38/15/0/0; smokers=91 (89%), non-squamous cell carcinoma/squamous cell carcinoma=66/36, PD-L1 tumor proportion score (TPS) ≥50%/1-49%=80/22, positive for EGFR mutation=5, advanced/postoperative recurrence=51/51, treatment line: first/second or later=81/21, treatment courses: median 8 (range: 1-39), objective response rate/disease control rate=44%/55%, immune-related adverse events (irAEs): 47, 5-year OS=34%]. On univariate analysis, PS, PD-L1 TPS, and irAEs were significant prognostic factors. On multivariate analysis, histology, PD-L1 TPS, and irAEs were significant prognostic factors. Conclusion: Pembrolizumab monotherapy demonstrated promising treatment outcomes for advanced or recurrent NSCLC, as evidenced by the significant association of PD-L1 TPS with irAEs and prognosis, suggesting its potential as a beneficial therapeutic option.

Investigating the Correlation Between Long-Term Response in Patients with Metastatic HER2+ Breast Cancer and the Activity of Regulatory T Cells: A Retrospective Study.

Background: Trastuzumab is commonly utilized in the management of metastatic HER2-positive breast cancer. Our main goal was to examine the clinical outcomes and immune markers of patients who received trastuzumab and chemotherapy treatment. Methods: Between 1995 and 2012, a total of 98 patients diagnosed with metastatic HER2-positive breast cancer were retrospectively analyzed at Ege University Hospital and Tepecik Training and Research Hospital. The clinicopathological characteristics and clinical outcomes of the patients were assessed, and the associations between response rates, survival and the immune profiles of tumor infiltrating lymphocytes were statistically evaluated. Results: The average age of patients at the time of diagnosis was 50.1±10.3 (ranging from 30 to 79) years. The mean follow-up period for all patients was 97.9±53.8 months. Among the patients, complete response was observed in 24.5%, partial response in 61.2%, and stable disease in 8.2% of cases. The average progression-free survival was 50.3±26.9 months (ranging from 1 to 163 months), and the average overall survival was 88.8±59.4 months (ranging from 12 to 272 months). After analyzing all cases, it was found that patients who were younger (p=0.006), exhibited higher CD3-positivity (p=0.041), presented with higher FOXP3-positivity (p=0.025), showed complete or at least partial response to treatment (p=0.008), and experienced a long-term response to trastuzumab (and chemotherapy) treatment had longer survival (p=0.001). Conclusion: Patients with HER2-positive breast cancer, who initially respond positively to palliative trastuzumab and chemotherapy treatment, can achieve long-term tumor remission lasting for several years.

Present state and perceived future use of teledentistry in long-term care facilities in Japan: A cross-sectional study.

Objectives: Teledentistry could be effective in managing oral health through the provision of oral hygiene instruction and diagnostic services. This study aimed to assess the perception and usefulness of teledentistry in Japanese long-term care facilities. Methods: We conducted a questionnaire survey to compare related factors of the usefulness of teledentistry and identify issues in its implementation. We chose 1000 facilities using a stratified random sampling method. The questionnaires were sent to the facilities in August 2021 and collected in December of the same year. Responses to the questionnaire items regarding the usefulness of teledentistry for oral management were divided into three groups according to the answer: perceiving teledentistry as "useful," "not useful," or "neither," including facilities that do not currently use teledentistry. Results: In total, 26.1% (261) responded to the questionnaire, and among these, 184 facilities answered the question regarding the usefulness of teledentistry. Only two of these facilities implemented teledentistry. Facilities with dental hygienists (p = 0.040) and those that receive insured medical treatment: reimbursement for oral feeding maintenance II (p = 0.040) tended to perceive teledentistry as useful in the management of patients with coronavirus disease. The higher the number of services that responded to the question "what kind of services do you think can be provided via teledentistry?" the higher the percentage of "useful" responses. Conclusions: Although only a few facilities use teledentistry, many long-term care facilities perceive it as useful even without using it. The presence of dental hygienists and interprofessional work done with reimbursement for oral feeding maintenance II contributed to the perception of the usefulness of teledentistry in long-term care facilities.

Extensivist: improving the delivery of enhanced health in older people's care homes.

BACKGROUND: Older people living in care homes are often frail and clinically complex. The Enhanced Health in Care Homes (EHCH) framework supports organisational and clinical strategies to deliver good care, promoting proactive person-centred care by whole system collaboration. We evaluate the impact of a new role, the Extensivist, in the delivery of EHCH for older people living in care homes. AIMS: To evaluate implementation processes and the clinical utility of the Extensivist in older people care homes in the London borough of Southwark. METHODS: The Extensivist (Band 8a Advanced Nurse Specialist skilled in frail older people) was embedded within the care home general practitioners (GP) service for a 2-year pilot (2019-2021). Implementation processes were evaluated. Impact of the Extensivist role was evaluated by the number of Comprehensive Geriatric Assessment (CGA) completed, interventions and other clinical activity performed as well as qualitative case studies and semistructured feedback from care home workers and professionals. RESULTS: The Extensivist feasibly delivered CGA and implemented intervention plans. The role iteratively developed to support wider aspects of care including advance care planning (ACP) and training. Challenges included building trust, the time-consuming nature of CGA, ACP and coordinated communication. Case studies and semistructured feedback indicated the role was considered valuable in the delivery of clinical care, supporting residents, families, care homes and GPs and as a resource for education for care home workers. CONCLUSIONS: The Extensivist is a valuable resource and a linchpin in the delivery of EHCH framework in care homes for older adults in Southwark. Further evaluations to assess reproducibility in other areas of the UK are warranted.

CONTACT: a non-randomised feasibility study of bluetooth-enabled wearables for contact tracing in UK care homes during the COVID-19 pandemic.

BACKGROUND: The need for effective non-pharmaceutical infection prevention measures such as contact tracing in pandemics remains in care homes, but traditional approaches to contact tracing are not feasible in care homes. The CONTACT intervention introduces Bluetooth-enabled wearable devices (BLE wearables) as a potential solution for automated contact tracing. Using structured reports and reports triggered by positive COVID-19 cases in homes, we fed contact patterns and trends back to homes to support better-informed infection prevention decisions and reduce blanket application of restrictive measures. This paper reports on the evaluation of feasibility and acceptability of the intervention prior to a planned definitive cluster randomised trial of the CONTACT BLE wearable intervention. METHODS: CONTACT was a non-randomised mixed-method feasibility study over 2 months in four English care homes. Recruitment was via care home research networks, with individual consent. Data collection methods included routine data from the devices, case report forms, qualitative interviews (with staff and residents), field observation of care, and an adapted version of the NoMaD survey instrument to explore implementation using Normalisation Process Theory. Quantitative data were analysed using descriptive statistical methods. Qualitative data were thematically analysed using a framework approach and Normalisation Process Theory. Intervention and study delivery were evaluated against predefined progression criteria. RESULTS: Of 156 eligible residents, 105 agreed to wear a device, with 102 (97%) starting the intervention. Of 225 eligible staff, 82% (n = 178) participated. Device loss and damage were significant: 11% of resident devices were lost or damaged, ~ 50% were replaced. Staff lost fewer devices, just 6%, but less than 10% were replaced. Fob wearables needed more battery changes than card-type devices (15% vs. 0%). Structured and reactive feedback was variably understood by homes but unlikely to be acted on. Researcher support for interpreting reports was valued. Homes found information useful when it confirmed rather than challenged preconceived contact patterns. Staff privacy concerns were a barrier to adoption. Study procedures added to existing work, making participation burdensome. Study participation benefits did not outweigh perceived burden and were amplified by the pandemic context. CONTACT did not meet its quantitative or qualitative progression criteria. CONCLUSION: CONTACT found a large-scale definitive trial of BLE wearables for contact tracing and feedback-informed IPC in care homes unfeasible and unacceptable - at least in the context of shifting COVID-19 pandemic demands. Future research should co-design interventions and studies with care homes, focusing on successful intervention implementation as well as technical effectiveness.

The prognostic value of [18F]FDG PET/CT texture analysis prior to transplantation for unresectable colorectal liver metastases.

INTRODUCTION: To determine whether heterogeneity in colorectal liver metastases (CRLM) 18F fluorodeoxyglucose [18F]FDG distribution is predictive of disease-free survival (DFS) and overall survival (OS) following liver transplantation (LT) for unresectable CRLM. METHODS: The preoperative [18F]FDG positron emission tomography/computed tomography examinations of all patients in the secondary cancer 1 and 2 studies were retrospectively assessed. Maximum standardized uptake value (SUVmax), metabolic tumour volume (MTV), and six texture heterogeneity parameters (joint entropyGLCM, dissimilarityGLCM, grey level varianceSZM, size zone varianceSZM, and zone percentageSZM, and morphological feature convex deficiency) were obtained. DFS and OS for patients over and under the median value for each of these parameters were compared by using the Kaplan Meier method and log rank test. RESULTS: Twenty-eight out of 40 patients who underwent LT for unresectable CRLM had liver metastases with uptake above liver background and were eligible for inclusion. Low MTV (p < 0.001) and dissimilarityGLCM (p = 0.016) were correlated to longer DFS. Low MTV (p < 0.001) and low values of the texture parameters dissimilarityGLCM (p = 0.038), joint entropyGLCM (p = 0.015) and zone percentageSZM (p = 0.037) were significantly correlated to longer OS. SUVmax was not correlated to DFS and OS. CONCLUSION: Although some texture parameters were able to significantly predict DFS and OS, MTV seems to be superior to predict both DFS and OS following LT for unresectable CRLM.

Sex differences in glutamate transmission and plasticity in reward related regions.

Disruptions in glutamate homeostasis within the mesolimbic reward circuitry may play a role in the pathophysiology of various reward related disorders such as major depressive disorders, anxiety, and substance use disorders. Clear sex differences have emerged in the rates and symptom severity of these disorders which may result from differing underlying mechanisms of glutamatergic signaling. Indeed, preclinical models have begun to uncover baseline sex differences throughout the brain in glutamate transmission and synaptic plasticity. Glutamatergic synaptic strength can be assessed by looking at morphological features of glutamatergic neurons including spine size, spine density, and dendritic branching. Likewise, electrophysiology studies evaluate properties of glutamatergic neurons to provide information of their functional capacity. In combination with measures of glutamatergic transmission, synaptic plasticity can be evaluated using protocols that induce long-term potentiation or long-term depression. This review will consider preclinical rodent literature directly comparing glutamatergic transmission and plasticity in reward related regions of males and females. Additionally, we will suggest which regions are exhibiting evidence for sexually dimorphic mechanisms, convergent mechanisms, or no sex differences in glutamatergic transmission and plasticity and highlight gaps in the literature for future investigation.

Postmenopausal Shrinkage of Uterine Myomas: A Retrospective Study of 97 Cases Monitored Annually for 10 Years.

Introduction and aim Both patients and gynecologists are concerned about how much and how quickly myomas shrink after menopause. This study aimed to elucidate clinical findings that may be associated with postmenopausal shrinkage of uterine myomas. Materials and methods This study included 97 patients who underwent menopause by August 2012, had myoma nodules with the longest diameter between 50 mm and 160 mm, and visited our specialized myoma clinic annually for at least 10 years after menopause. They underwent transabdominal ultrasonography at least once per year. An experienced gynecologist measured the longest diameter of myoma nodules with a maximum diameter between 50 mm and 160 mm. The shrinkage rate of myoma diameters after menopause compared to premenopausal diameters was calculated each year for 10 years. The shrinkage rate of the longest diameter of the largest nodule 10 years after menopause (10-year shrinkage rate) and its relationship with clinical findings (the age at menopause, parity, body mass index {BMI}, number of nodules, MRI findings on T2-weighted image, location of the nodule, and longest diameter of the largest nodule before menopause) were analyzed. Additionally, we examined annual changes in shrinkage rate of myomas over a 10-year period after menopause (annual trend), and the relationship between annual trends and factors such as BMI and the number of nodules. Results In this examination of 10-year shrinkage rate, the group with a BMI of less than 25 showed a significantly greater shrinkage rate compared to the group with a BMI of 25 or more (25.0% vs 15.7%, p=0.023). Additionally, the group with a single nodule showed a significantly greater 10-year shrinkage rate compared to the group with four or more nodules (26.3% vs 15.2%, p=0.036). For annual trends, the rate of change in the first two years after menopause was significantly faster compared to the trend from the third to the 10th year (difference in slope: 3.888 points per year, p<0.001). When divided into two groups based on the number of nodules (one or two nodules group and three or more nodules group), the group with one or two nodules showed a significant difference in the shrinkage rate between up to two years after menopause and from the period from the third to the 10th year (difference in slope: 4.590 points per year, p<0.001). However, for the group with three or more nodules, there was no significant difference in the annual trend between the first two years after menopause and the rate from the third to the 10th year (difference in slope: 1.626 points per year, p=0.107). Conclusion BMI and the number of myoma nodules were significantly related to the 10-year shrinkage rate. Although myomas shrank significantly faster within the first two years after menopause compared to the later period, the early annual trend did not differ significantly from the trend in the later period when there were multiple nodules with a maximum diameter of 50 mm or more.

Correlation between organizational support, self-efficacy, and core competencies among long-term care assistants: a structural equation model.

Introduction: Long-term care assistants are taking on more important roles in the healthcare system. The purpose of this study was to investigate what demographic factors influence the core competencies of nursing assistants, as well as to investigate the levels of organizational support, self-efficacy, and core competencies among nursing assistants in China, to explore the relationship between them. Methods: This is a cross-sectional study with prospective data collection based on a self-report questionnaire. A total of 320 long-term care assistants from two healthcare institutions. We collected socio-demographic characteristics and measured their perceived organizational support, self-efficacy, and core competency levels of the participants. Pearson correlation tests were conducted to examine the relationships among three variables, and a structural equation model was developed to test the interrelationships among these variables. Results: The results indicated that age, employment type, licensing status, monthly income, pre-job training, and training methods were associated with core competency, with nursing knowledge identified as a weak area in core competencies. There were significant associations among each dimension of perceived organizational support, self-efficacy, and core competencies (p < 0.01). The structural equation model demonstrated good fit: X 2/df = 2.486, GFI = 0.974, CFI = 0.988, IFI = 0.988, TLI = 0.977, RMSEA = 0.068, SRMR = 0.013. The direct effect of organizational support on core competencies was 0.37, with self-efficacy mediating the relationship between organizational support and core competencies, yielding an indirect effect of 0.122 and a total effect coefficient of 0.492 (all p < 0.001). Conclusion: Training in core competencies should prioritize nursing knowledge. Enhanced perceived organizational support and self-efficacy among nursing assistants were associated with higher core competencies.

Recurrence rates with long-term follow-up after hallux valgus surgical treatment using shaft metatarsal osteotomies: a systematic review and meta-analysis.

Purpose: Recurrence of hallux valgus (HV) following corrective surgery is a frequent concern. A recent systematic review estimated recurrence of HV in only 4.9%, which may be an underestimation, as most included studies had short- to mid-term follow-up. The purpose of this systematic review and meta-analysis was to synthesize and critically appraise the literature on the long-term outcomes of shaft osteotomies of the first metatarsal (M1) to treat HV without inflammatory disease or degenerative arthritis, and to assess the long-term HV recurrence rates of studies with a minimum follow-up of 5 years. Methods: This systematic review conforms to the PRISMA guidelines. The authors conducted a search using PubMed, Embase®, and Cochrane Central Register of Controlled Trials databases. Studies that report outcomes of shaft osteotomies of the M1 for non-inflammatory and non-degenerative HV having a minimum follow-up of 5 years were included. We found five eligible studies comprising six datasets, all assessed Scarf osteotomies with a mean follow-up that ranged from 8 to 14 years. Results: The HV recurrence rate was 40%, considering the threshold of >15° hallux valgus angle (HVA), 30% having >20°, and 2% having >25°. Conclusion: At a minimum follow-up of 8 years following shaft osteotomies of M1, the HVA was 15.9°, the intermetatarsal angle (IMA) was 7.7°, and the DMAA was 8.3°. Furthermore, the recurrence rates considering the various thresholds of HVA were: 40% having >15°, 20% having >20°, and 2% having >25°. Level of Evidence: Meta-analysis, Level IV.

Machine learning-based modeling of surface water temperature dynamics in arctic lakes.

Lake surface-water temperature (LSWT) regulates physical and biochemical processes in lakes. Therefore, understanding the LSWT dynamics is important, especially in Arctic zone since the region is experiencing a warming rate that is greater than the Earth's average. However, regular measurements of LSWT in the remote Arctic lakes always face difficulties or cannot be done by satellites accurately due to the cloud cover and their limited spatiotemporal resolution. Here, we used a historically rich data (1960-2023) to develop four machine learning-based algorithms for the daily LSWT modeling in Lake Inari, situated in Arctic zone, using the air-temperature data. Our results showed that both air-temperature (0.030 °C/yr) and LSWT (0.023m °C/yr) were warming with a rate faster than those in the globe. The long-short-term memory model, with the coefficients of determination varied from 0.96 to 0.98, outperformed other algorithms in modeling of the daily LSWT dynamics in Lake Inari, followed by both support vector regression and neural network tools, and random forest model. As the air-temperature data are widely accessible through synoptic stations and remote sensing techniques, our suggested models can be simply adopted for other Arctic lakes, where the local water-temperature data are often lacking or contain large windows of missing data due to harsh atmospheric conditions and equipment failure.

Efficacy of Long-Term Intensive Straw Phonation Exercise in Air for Hyperfunctional Voice Disorders: A Preliminary Study.

PURPOSE: Literature highlights the efficacy of prolonged use of straw phonation for vocally healthy individuals. Nevertheless, minimal studies have examined the prolonged use of single treatment in hyperfunctional voice disorders (HFVD), as straw phonation is used as physiological training to improve voice quality in these individuals. The present study aimed to investigate the long-term intensive training effect of straw phonation exercise in air (SPEA) for HFVD. METHOD: In a time series design, seven females with HFVD (mean age 42.28years) participated in SPEA for 12 long sessions (30 minutes/session) intensively trained for 3weeks (4days/week). The participant-recorded voice samples were analyzed for aerodynamic measures Aerodynamic Subglottic Pressure (ASP), Airflow Rate (AFR), glottal behavior measures Contact Quotient (CQ), Contact Quotient Range (CQR), acoustic measure Acoustic Voice Quality Index (AVQI), auditory-perceptual Consensus Auditory Perceptual Evaluation of Voice - Kannada (CAPE-V-K), and self-perceptual measure Voice Handicap Index - Kannada (VHI-K) at pre-therapy, mid-therapy, post therapy, and 1-month follow-up timelines. Related Friedman's two-way analysis of variance and post hoc Wilcoxon signed-rank test were used to analyze the change in outcome measures across therapy timelines. RESULTS: Significant reduction in ASP, CQR, AVQI, CAPE-V-K, and VHI-K measures from pre-therapy to post-therapy and follow-up timelines was observed. Although there was a decrease in AFR and CQ measures from pre therapy to post therapy and follow-up, no significant differences were observed. No significant changes were observed from pre therapy to mid-therapy in any outcome measures, indicating the need for extended therapy duration and regular practice. CONCLUSION: These findings provide preliminary evidence of implementing the long-term intensive training of SPEA for HFVD with the support of significant outcome measures at various therapy timelines.

Healthcare professionals' experience with nutritional care beyond formal quality systems - A qualitative study.

BACKGROUND: Numerous formal strategies, screening tools, and interventions have been used to prevent malnutrition in long-term care patients. Despite these efforts, the proportion of screened patients is low, and a large proportion are malnourished. Previous research has revealed that healthcare professionals use a broad approach in their nutritional care but has also emphasised the need for further investigation into these approaches. OBJECTIVE: To explore how healthcare professionals working in long-term care experience and apply nutritional care. DESIGN: A descriptive, exploratory, qualitative design containing 240 h of participant observation, 12 focus groups and 2 individual interviews. SETTING(S): Twelve nursing homes and home care units in three Norwegian municipalities. PARTICIPANTS: Participant observation of interactions between healthcare professionals and patients. Forty-three registered nurses participated in focus group or individual interviews. METHODS: The data were analysed using inductive thematic analysis. RESULTS: The analysis identified three themes: The first theme, limited significance of nutritional screening, showed that healthcare professionals experienced the limited value of nutritional screening, as it often did not capture patients' nutritional challenges. They also perceived nutritional screening as unsuitable for patients at the end of their lives, those with overweight-related complications, or undergoing rehabilitation. In addition, nutritional screening was perceived as something healthcare professionals did for their managers or administrators, not because it was crucial to providing good nutritional care. The second theme, provision of individualised food, captures the healthcare professionals' efforts in adapting and preparing food according to the patient's preferences. Facilitation to enable patients to make individual food choices and the use of food cards or lists were two approaches to individualising nutrition care. The third theme, making meals more than about food, elucidated how healthcare professionals used meals to help patients cope with their situations and experience social belonging. Conversations about or around meals were used to provide patients with a sense of belonging to their past or present situation. The meals were also used as a diversion strategy for patients with unrest, as arenas for daily activity training, and for meaningful social interactions between patients around the tables. CONCLUSIONS: Nutritional screening and prevention of malnutrition are only one part of healthcare professionals' nutritional care. Individualised food and meals that create coping, a sense of belonging, and social experiences are equally important parts of their care. Emphasising healthcare professional's person-centred approach to nutritional care would be beneficial, as it could strengthen and further develop long-term nutritional care services.

Long-term immunogenicity of the SA14-14-2 Japanese encephalitis (JE) vaccine (CD.JEVAX®) booster following chimeric JE (IMOJEV®) vaccine priming in Thai children.

Japanese encephalitis (JE) is a significant public health concern in Asia, particularly in children, where vaccination plays a crucial role in prevention. In this study, we investigated the immunogenicity and safety of two different live-attenuated JE vaccines used as primary and booster doses. Fifty healthy participants aged 1-3 years, who were primed with the chimeric JE vaccine IMOJEV® a year earlier, received a booster dose of the SA14-14-2 JE vaccine CD.JEVAX®. To evaluate the immune response, JE-neutralizing antibody titers were assessed on day 0 (pre-booster), day 30, and annually from 1 to 5 years post-booster using the 50% plaque reduction neutralization test (JEPRNT50). The assessment revealed strong immunogenicity 30 d post-booster, with a geometric mean titer of 2092.4 [95% confidence interval (CI): 1473.9-2970.5] and a seroprotection rate of 100%, which gradually decreased to 97.5% at 5 years post-booster. No severe adverse events were observed. The most common reaction within 7 d of vaccination was fever (20%; 95% CI: 10.7-32.3). These results indicate that a booster dose of CD.JEVAX® elicits a strong immune response in children previously vaccinated with IMOJEV® while maintaining a good safety profile, thus supporting the interchangeability of these two live-attenuated JE vaccines. Registered at www.thaiclinicaltrials.org (TCTR ID: TCTR20221102003), our study suggests that CD.JEVAX® can be a viable option for booster vaccination in JE prevention programs, potentially enhancing vaccine flexibility and accessibility.

Efficacy and safety of shorter multidrug-resistant or rifampicin-resistant tuberculosis regimens: a network meta-analysis.

BACKGROUND: Drug-resistant tuberculosis (DR-TB) remains a threat to public health. Shorter regimens have been proposed as potentially valuable treatments for multidrug or rifampicin resistant tuberculosis (MDR/RR-TB). We undertook a systematic review and network meta-analysis to evaluate the efficacy and safety of shorter MDR/RR-TB regimens. METHODS: We searched PubMed/MEDLINE, Cochrane Center for Clinical Trials (CENTRAL), Scopus, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, US Food and Drug Administration, and Chinese Clinical Trial Registry for primary articles published from 2013 to July 2023. Favorable (cured and treatment completed) and unfavorable (treatment failure, death, loss to follow-up, and culture conversion) outcomes were assessed as the main efficacy outcomes, while adverse events were assessed as the safety outcomes. The network meta-analysis was performed using R Studio version 4.3.1 and the Netmeta package. The study protocol adhered to the PRISMA-NMA guidelines and was registered in PROSPERO (CRD42023434050). RESULT: We included 11 eligible studies (4 randomized control trials and 7 cohorts) that enrolled 3,548 patients with MDR/RR-TB. Treatment with a 6-month combination of BdqLzdLfxZTrd/Eto/H had two times more favorable outcomes [RR 2.2 (95% CI 1.22, 4.13), P = 0.0094], followed by a 9-11 month combination of km/CmMfx/LfxPtoCfzZEHh [RR1.67 (95% CI 1.45, 1.92), P < 0.001] and a 6-month BdqPaLzdMfx [RR 1.64 (95% CI 1.24, 2.16), P < 0.0005] compared to the standard longer regimens. Treatment with 6 months of BdqPaLzdMfx [RR 0.33 (95% CI 0.2, 0.55), P < 0.0001] had a low risk of severe adverse events, followed by 6 months of BdqPaLzd [RR 0.36 (95% CI 0.22, 0.59), P ≤ 0.001] and BdqPaLzdCfz [RR 0.54 (95% CI 0.37, 0.80), P < 0.0001] than standard of care. CONCLUSION: Treatment of patients with RR/MDR-TB using shorter regimens of 6 months BdqLzdLfxZTrd/Eto/H, 9-11 months km/CmMfx/LfxPtoCfzZEHh, and 6 months BdqPaLzdMfx provides significantly higher cure and treatment completion rates compared to the standard longer MDR/RR-TB. However, 6BdqPaLzdMfx, 6BdqPaLzd, and 6BdqPaLzdCfz short regimens are significantly associated with decreased severity of adverse events. The findings are in support of the current WHO-recommended 6-month shorter regimens.
