Abstract
We investigate how altering the interface geometry from a zigzag to a glide plane interface between two topologically distinct valley Hall emulating photonic crystals (VPC), profoundly affects edge states. We experimentally observe a transition from gapless to gapped edge states, accompanied by the occurrence of slow light within the Brillouin zone, rather than at its edge. We numerically simulate the propagation and measure the transmittance of the modified edge states through a specially designed valley-conserving defect. The robustness to backscattering gradually decreases, suggesting a disruption of valley-dependent transport. We demonstrate the significance of interface geometry to gapless edge states in a VPC.

Abstract
Introduction The present inquiry seeks to investigate whether the current regimens of QSEs (Quadriceps-Strengthening Exercises) aggravate the disease while mitigating symptoms. Materials and methods A comparative study was conducted on 32 patients with medial compartment osteoarthritis of knees. While the neutral group of 16 patients was constituted of those with an anatomical-lateral-femoro-tibial-angle (aFTA) 176-180º, varus group comprised an equal number of patients with an aFTA >180º. A home-based 12-week strength-training program involving weekly visits to hospital for supervised sessions was administered. The outcome measures were visual-analog-scale (VAS), medial patello-femoral joint tenderness (MPFJT), time-up-and-go-test (TUGT), stair-climb test, step test, WOMAC, IKDC scores, aFTA, hip-knee-ankle (HKA) angle, lateral-tibio-femoral-joint-separation (LTFJS), and horizontal-distance-from-centre-of-knee-to-Mikulicz-line. Results There was a significant increase in quadriceps strength (p<0.01) in both groups. Values for neutral group with VAS score (p=0.01), MPFJT (p=0.01), TUGT (p=0.01), timing of the stair climb test (p=0.01), WOMAC (p<0.01), and IKDC (p=0.03) were better compared to varus group with VAS score (p=0.13), MPFJT (p=0.03), TUGT (p=0.90), timing of stair climb test (p=0.68), WOMAC (p<0.02), and IKDC (p=0.05). Varus group also showed an increase in aFTA and LTFJS in 12 patients, increase in HKA in 11, and increase in horizontal distance from the centre of knee to the Mikulicz line in 7 patients. Conclusion The present study brings to the fore the paradoxical role played by QSEs in management of medial knee OA. While there is a radiological progression of the disease in both neutral and varus mal-aligned knees more so in the latter than the former.

Abstract
BACKGROUND Virtual care may improve access to healthcare and may be well suited to digitally connected youth, but experts caution that privacy and technology barriers could perpetuate access inequities. Success of virtual care will depend on its alignment with patient preferences. However, information on preferences for virtual and in-person healthcare is missing, especially for youth. We sought to quantify preferences for and barriers to virtual versus in-person mental and physical healthcare in youth and their parents, including in vulnerable segments of the population such as families with a parent with severe mental illness (SMI). METHODS Participants were 219 youth and 326 parents from the Families Overcoming Risks and Building Opportunities for Wellbeing cohort from Canada, of which 61% of youth had at least one parent with SMI. Participants were interviewed about healthcare preferences and access to privacy/technology between October 2021 and December 2022. RESULTS Overall, youth reported a preference for in-person mental (66.6%) and physical healthcare (74.7%) versus virtual care or no preference, and to a somewhat lesser degree, so did their parents (48.0% and 53.9%). Half of participants reported privacy/technology barriers to virtual care, with privacy being the most common barrier. Preferences and barriers varied as a function of parent SMI status, socioeconomic status and rural residence. CONCLUSIONS The majority of youth and parents in this study prefer in-person healthcare, and the preference is stronger in youth and in vulnerable segments of the population. Lack of privacy may be a greater barrier to virtual care than access to technology.

Abstract
OBJECTIVES An infection surveillance system based on a hospital's digital twin [4D-Disease Outbreak Surveillance System (4D-DOSS)] is being developed in Singapore. It offers near-real-time infection surveillance and mapping capabilities. This early economic modelling study was conducted, using meticillin-resistant Staphylococcus aureus (MRSA) as the pathogen of interest, to assess the potential cost-effectiveness of 4D-DOSS. METHODS A Markov model that simulates the likelihood of MRSA colonization and infection was developed to evaluate the cost-effectiveness of adopting 4D-DOSS for MRSA surveillance from the hospital perspective, compared with current practice. The cycle duration was 1 day, and the model horizon was 30 days. Probabilistic sensitivity analysis was conducted, and the probability of cost-effectiveness was reported. Scenario analyses and a value of information analysis were performed. RESULTS In the base-case scenario, with 10-year implementation/maintenance costs of 4D-DOSS of $0, there was 68.6% chance that 4D-DOSS would be cost-effective. In a more pessimistic but plausible scenario where the effectiveness of 4D-DOSS in reducing MRSA transmission was one-quarter of the base-case scenario with 10-year implementation/maintenance costs of $1 million, there was 47.7% chance that adoption of 4D-DOSS would be cost-effective. The value of information analysis showed that uncertainty in MRSA costs made the greatest contribution to model uncertainty. CONCLUSIONS This early-stage modelling study revealed the circumstances for which 4D-DOSS is likely to be cost-effective at the current willingness-to-pay threshold, and identified the parameters for which further research will be worthwhile to reduce model uncertainty. Inclusion of other drug-resistant organisms will provide a more thorough assessment of the cost-effectiveness of 4D-DOSS.

Abstract
Although the advantages of developmental networks are well-known, most faculty do not know how to participate in such networks actively. Additionally, institutions face challenges in teaching faculty the best practices of networking. This deficiency constitutes a critical gap in the literature, which may slow career advancement for faculty, particularly from underrepresented groups. The study's purpose was to examine the effectiveness of a curriculum-based faculty training in developmental networks, utilizing the Extension for Community Health Outcomes (ECHO) platform. In this pre-post study, 33 faculty members participated in the intervention utilizing eight modules involving four competencies. Each module followed a standard format, including a short didactic, two facilitated case study discussions based on real-life scenarios, and self-reading of selected literature. Outcomes included (i) change in knowledge scores obtained from two questions per module and (ii) self-efficacy scores measured on a scale of 0-100. Paired student's t-test and mixed model regression analyses were used. A significant increase in knowledge score was documented using mixed model regression for 4 of the eight modules (mean change score 0.4-0.8, p≤0.03 for all analyses). The proportion of faculty participants reporting correct knowledge items for all modules increased from 49.8% (pre) to 64.3% (post), which was statistically significant (p<0.001). Significant increases in paired self-efficacy scores were reported for each of the eight modules (mean change score 17-37, p<0.05 for all analyses). This study highlights the importance of curriculum-based training in networking. Participants showed a significant increase in pre-post networking self-efficacy and knowledge scores. Our ECHO-based curriculum, facilitator training, and manual enable easy implementation in other institutions, ensuring scalability and adaptability. Our analysis provides the evidence basis for examining the impact of a developmental network intervention in enhancing individual career networks.

Abstract
Poultry litter (PL) and rice straw (RS), commonly available waste materials, pose severe threat to environment, if not properly managed. As viable waste treatment method, vermi-transformation of PL into enriched vermimanure was done using RS and cow dung (CD) with different feedstocks (FS) combinations like FS0(CD without earthworm), FS1(CD), FS2(1CD: 1RS), FS3(1CD: 1PL) and FS4(1CD: 1RS: 1PL) for 110 days. Increased growth performance (P < 0.05) of Eisenia fetida, macronutrient levels, and a consistently lower carbon-to-nitrogen ratio (C/N) emphasize the importance of RS and PL in the vermimanuring process. Several analytical techniques have revealed the presence of functional groups, nitrate (NO3-), phosphate (PO43-), and potassium ions (K+) as well as the high porosity of the matured vermimanures. Therefore, using earthworms, the feedstock FS4(1CD: 1RS: 1PL) could be successfully biotransformed into sustainable manure lowering the usage of chemical fertilizers and rice straw burning.

Abstract
Gut microbiota includes the microbes present in the gut; these microbes are an essential component in maintaining a healthy gut. Gut microbiota has a wide range of functions, including effects on colonization, pathogen resistance, intestinal epithelial maintenance, metabolizing food and pharmaceutical chemicals, and influencing immunological functions. Every disease associated with the gut starts due to a disbalance in the composition of the gut microorganisms and can be managed by balancing the composition of gut bacteria using various herbal remedies. Mentha herbs are a variety of perennial herbs that are grown commercially in various parts of the world. Mentha is a potent herb that shows anticholinergic action and can block PGE2 and GM1 receptors and interact with cholera toxins; it is used traditionally in different systems of medicines to treat various gastrointestinal diseases associated with the gut. Mentha herbs have potent bactericidal, viricidal, and fungicidal properties. Mentha has been used to cure stomach and digestion issues as well as to treat a variety of disorders. This review article summarizes diseases associated with the gut, the composition, and function of gut microbiota, and mentha's effectiveness along with its extraction methods and traditional uses. Research findings revealed that mentha could be an essential source against a wide range of diseases, especially gastrointestinal disorders. From its ayurvedic claims to its present use, various confirmed its clinically effective for human health. The present work also describes the mechanism of action along with the bioactives present in this well-known herb from Ayurveda.

Abstract
Abstract
Background
England has a health system offering universal coverage, but disparities in healthcare use are increasing. Between 2007-2017, children living in more deprived areas had higher rates of unplanned care (Emergency Department (ED) attendance and hospital admissions), whereas children from less deprived areas had higher rates of planned care (General Practitioner (GP) contact and outpatient appointments). More detailed research to find solutions for this divergent pattern is required.
Aim
To assess the rates of GP contact, outpatient appointments, hospital admissions and ED attendance in North West London, by Index of Multiple Deprivation (IMD) decile of home postcode and access to an integrated care service providing linked care between multiple child health professionals ‘Connecting Care for Children (CC4C)', for children aged 0-18 years between 2015-2019.
Methods
Retrospective analysis of a de-identified database of integrated care records for 495,357 children.
Results
Children from the most deprived decile had higher rates of emergency admissions (0.070 per child per year vs. overall mean 0.040), elective admissions (0.076 vs. 0.032), ED attendances (0.754 vs. 0.358) and outpatient appointments (1.702 vs. 0.756) between 01.01.2015- 31.12.2019. Children from the least deprived decile had the second highest rates of outpatient appointments (0.911 vs. 0.756) and GP contact (8.192 vs. 5.390) between 01.01.2015- 31.12.2019. Children with access to the CC4C service, despite being from more deprived backgrounds, had lower rates of emergency admissions (0.028 vs. 0.037) compared to patients with access to usual care. P values <0.001 in all cases.
Conclusions
Greater deprivation was linked to higher rates of emergency admissions, but this was partially mitigated by access to more integrated healthcare models. Children from the least deprived decile continued to have disproportionately higher use of planned care.
Key messages
• Despite universal health coverage, children from more deprived areas continue to have disproportionately higher use of unplanned care.
• Further research is required to explore whether integrated care solutions can reduce the burden on unplanned health services and inequalities in access to care.

Abstract
The purpose of this study was to compare and correlate disease activity score including 28 joints counts (DAS-28) Squeeze with DAS-28 and clinical disease activity index (CDAI) to assess disease activity (DA) in rheumatoid arthritis (RA) patients. A total of 100 RA patients were included in the study. All subjects were evaluated for disease activity using the DAS-28 Squeeze, DAS-28, and CDAI. Spearman’s rho (ρ) was calculated to determine the correlation between DAS-28 Squeeze, DAS-28, and CDAI. Cross-tabulation was performed to compare and calculate the kappa coefficient for the link between two indices. For each scale, Cronbach’s alpha was also calculated to test dependability. The average age of the study group was 43.9±11.3. The mean scores on the DAS-28 Squeeze, DAS-28, and CDAI were, respectively, 3.58±1.06, 5.06±1.56, and 22.81±14.92. p=0.001 indicated a significant correlation between DAS-28 Squeeze and DAS-28 (ρ=0.986) and CDAI (ρ=0.939) for DAS-28 Squeeze. There was a considerable correlation between all three measures at various DA levels. Cronbach’s alpha for DAS-28 Squeeze, DAS-28, and CDAI were respectively 0.716, 0.663, and 0.734. DAS-28 Squeeze exhibited a substantial positive association with DAS-28 and CDAI for assessing disease activity and appears to be a more useful and reliable method than DAS-28 and CDAI for monitoring disease activity in RA patients.

Abstract
We measure the local near-field spin in topological edge state waveguides that emulate the quantum spin Hall effect. We reveal a highly structured spin density distribution that is not linked to a unique pseudospin value. From experimental near-field real-space maps and numerical calculations, we confirm that this local structure is essential in understanding the properties of optical edge states and light-matter interactions. The global spin is reduced by a factor of 30 in the near field and, for certain frequencies, flipped compared to the pseudospin measured in the far field. We experimentally reveal the influence of higher-order Bloch harmonics in spin inhomogeneity, leading to a breakdown in the coupling between local helicity and global spin.

Abstract
BACKGROUND Erectile dysfunction(ED) in men is a frequent under-reported complication of diabetes mellitus, which is becoming significant health problem worldwide. AIMS The study aims to determine the prevalence and risk factors for development of ED in North Indian patients with type 2 diabetes mellitus. METHODS We used international index of erectile function (IIEF-5) for the assessment of ED in 796 patients with type 2 diabetes mellitus. We recorded the age, duration of diabetes, glycemic status, body mass index, diabetes medications, microvascular and macrovascular complications. RESULTS The mean age of patients in the study was 49.38 ± 9.52 years. The prevalence of ED in patients with type 2 diabetes mellitus was 79.4%. Logistic regression analysis revealed that age, body mass index, glycemic control, insulin therapy, retinopathy and nephropathy was not significantly associated with erectile dysfunction in patients with type 2 diabetes mellitus. Duration of diabetes (OR = 1.054, 95% CI 1.007 to 1.102, P=0.023) and vibration perception threshold (OR = 1.071, 95% CI 1.042 to 1.102, P=0.000) were identified as key risk factors for development of ED. CONCLUSION Duration of diabetes and peripheral neuropathy emerged as significant risk factors for development of severe erectile dysfunction.

Abstract
Purpose Severe COVID-19 ARDS related end stage lung fibrosis with irreversible changes is a newer indication for lung transplantation with acceptable survival rate. Airway complication post lung transplant is a major source of morbidity and mortality with incidence as high as 25 to 49 percent. Patients with end stage COVID-19 fibrosis are likely to be clinically deconditioned with long duration of extracorporeal oxygenator (ECMO) support, high burden of sepsis and prolonged respiratory support which may affect the airways post lung transplantation. Methods This is a retrospective observational study after obtaining institutional ethical clearance. We reviewed electronic medical data of patients who underwent lung transplantation for post COVID-19 ARDS related fibrosis. We evaluated the incidence and type of airway complications and the various therapeutic interventions applied for its management. Results Between May 2020 and September 2021 our centre performed 23 bilateral lung transplants for end stage COVID-19 ARDS related fibrosis. 22 patients were on ECMO support with mean duration of 50.9 days before transplantation. All patients underwent lung transplantation with central Veno-Arterial ECMO support with mean organ ischaemia time of 360±154 minutes. The incidence of airway complication in our study group was 56%. We observed anastomotic narrowing in 3(13%), distal airway narrowing in 4(17%) and sloughing/coating of anastomotic site in 5(22%) patients. Nonspecific inflammatory polypi around the bronchial anastomotic site were noticed in 4(17%) and mild airway anastomotic dehiscence in 2 subjects. 8(34%) patients required serial bronchoscopy and balloon dilatation; 2 among them mandated additional cautery usage. 2 cases underwent polypectomy, further 4 subjects needed bronchial stent placement. 5 (21%) recipients were discharged with Tracheostomy while rest were successfully decannulated in the ward. Conclusion We observed a high incidence of airway complications in post lung transplant for COVID-19 ARDS related fibrosis. Early detection, timely management and serial follow up is of paramount importance in this subset of patients.

Abstract
OBJECTIVE The rational use of medicines as per the World Health Organization (WHO) should be practiced globally. However, data regarding the completeness of the prescriptions and their rational use is lacking from developing countries like India. Thus, the aim of this study was to assess the prescribing patterns of drugs and completeness of prescriptions as per WHO core drug use and complementary indicators to provide real-life examples for the Indian Council of Medical Research (ICMR) online prescribing skill course for medical graduates. METHODS Prescriptions of the patients, fulfilling inclusion criteria, attending Outpatient Departments of various specialties of tertiary care hospitals, were collected by thirteen ICMR Rational use of medicines centers located in tertiary care hospitals, throughout India. Prescriptions were evaluated for rational use of medicines according to the WHO guidelines and for appropriateness as per standard treatment guidelines using a common protocol approved by local Ethics committees. RESULTS Among 4838 prescriptions, an average of about three drugs (3.34) was prescribed to the patients per prescription. Polypharmacy was noted in 83.05% of prescriptions. Generic drugs were prescribed in 47.58% of the prescriptions. Further, antimicrobials were prescribed in 17.63% of the prescriptions and only 4.98% of prescriptions were with injectables. During the prescription evaluation, 38.65% of the prescriptions were incomplete due to multiple omissions such as dose, duration, and formulation. CONCLUSION Most of the parameters in the present study were out of the range of WHO-recommended prescribing indicators. Therefore, effective intervention program, like training, for the promotion of rational drug use practice was recommended to improve the prescribing pattern of drugs and the quality of prescriptions all over the country.

Abstract
INTRODUCTION AND AIMS Fibrosis staging in patients with nonalcoholic fatty liver disease (NAFLD) is carried out through the application of stepwise algorithms but there is little real-world data on their use. Our aim was to calculate the number of patients with NAFLD and indeterminate or high risk for fibrosis, assessed through noninvasive scores, that consequently underwent further staging evaluation. MATERIALS AND METHODS A cross-sectional multicenter cohort study was conducted on patients with NAFLD evaluated by hepatologists within the time frame of June 1 and July 31, 2018. The FIB-4 and NAFLD fibrosis scores were calculated in all the patients, and if at least one of the scores suggested indeterminate or high risk for fibrosis, we believed the patient should have undergone additional fibrosis staging assessment. RESULTS The study included 238 patients. The median time interval from NAFLD diagnosis and inclusion in the analysis was 12.2 months (IQR 3.0-36.5). A total of 128 (54%) patients had at least one noninvasive score that suggested indeterminate or high risk for fibrosis but studies to confirm the fibrosis grade (elastography, biopsy, etc.) were performed on only 72 (56%). The main barriers encountered by the physicians for applying the staging algorithms were related to health insurance coverage and imaging study costs. CONCLUSIONS A high percentage of patients with NAFLD were at indeterminate or high risk for fibrosis, according to noninvasive scores, but additional studies were carried out on only half of them, showing low adherence to current recommendations.

Abstract
Abstract
Introduction
The prevalence and outcomes of polyvascular disease (PVD) in patients admitted with acute decompensated heart failure (ADHF) have not been previously reported, nor is it known whether associations differ for heart failure (HF) with reduced vs. preserved ejection fraction (HFrEF vs HFpEF, respectively).
Purpose
To investigate the relationship between atherosclerotic involvement of multiple arterial territories and mortality in patients hospitalized with ADHF.
Methods
The Atherosclerosis Risk in Communities (ARIC) study conducted hospital surveillance of adjudicated heart failure in 4 US areas from 2005–2014, with events verified by physician review. Medical histories were abstracted from the hospital record. PVD was defined by coexisting disease in ≥2 arterial beds, identified by prevalent coronary artery disease, peripheral arterial disease, and cerebrovascular disease. Mortality hazards of PVD vs. no PVD were analyzed separately for HFpEF and HFrEF, with adjustment for age, race, sex, year of admission and geographic region. All analyses were weighted by the inverse of the sampling probability.
Results
Of 24,936 ADHF hospitalizations (52% female, 32% Black, mean age 75 years), 19% had PVD (22% among HFrEF hospitalizations, 17% among HFpEF hospitalizations), Figure 1. There was an increasing trend in 1-year mortality with 0, 1 and ≥2 arterial bed involvement, both for patients with HFrEF (29% to 32% to 38%; P-trend=0.0006) and HFpEF (26% to 32% to 37%; P-trend <0.0001). After adjustments, PVD was associated with a 20% higher hazard of 1-year mortality in patients with HFrEF (HR=1.23; 95% CI: 1.06–1.44) and a 30% higher hazard in patients with HFpEF (HR=1.33; 95% CI: 1.09–1.63), with no significant interaction by HF type (P-interaction = 0.5).
Conclusion
Patients hospitalized with ADHF and coexisting PVD have an increased risk of death, irrespective of HF type. Clinical attention should be directed toward PVD, with secondary prevention strategies enacted to improve the prognosis of this vulnerable population.

Abstract
BACKGROUND Tricipital aponeurosis (TA) has gained attraction as a constant and reliable landmark to identify the location of radial nerve in the setting of fracture distal humeri. The aponeurosis itself shows variant anatomical patterns. In this study, we intend to provide a comprehensive description and functional classification of observed anatomical variations with possible clinical implications. MATERIALS AND METHODS Sixty arms belonging to 30 adult cadavers were studied. TA was examined grossly to document variations in its shape and classified accordingly. Subsequently, length and breadth of TA were measured. The distance of the radial nerve (RN) from the point of confluence and from the lateral border of TA was also measured (tricepso-radial distance [TRD]). These distances were correlated with the different patterns of TA obtained. RESULTS Based on the shape of the proximal apex of TA or point of confluence and frequency of their occurrence, we propose a new classification of 4 patterns for the TA anatomy. Pattern I: classically seen as the triangular proximal apex (76.67%); pattern II: tongue shaped or blunt proximal apex (18.33%); pattern III: bifurcated or dual proximal apex (3.33%); pattern IV: as the absence of TA (1.67%). The mean of length and breadth of TA was 16.58 ± 2.05 cm and 3.61 ± 0.61 cm, respectively. The mean distance of RN from point of confluence and lateral border of TA was 3.57 ± 0.19 cm and 2.04 ± 0.56 cm, respectively. The length, breadth of TA and TRD differs amongst the different patterns of TA. CONCLUSIONS Anatomical variations in the shape and size of TA are frequently encountered. The proposed, hitherto undescribed, classification may make operating surgeon aware of these morphological variations and help prevent iatrogenic injury to RN. Such classification is simple and unique; however, its success relies upon universal acceptance.

Abstract
Introduction: The movement and steadiness of the shoulder joint is due to both the dynamic and static stabilisers. Recurrent anterior shoulder instability is common due to the Bankart lesion or the Hill Sachs lesion. The bone loss and soft tissue failure due to these lesions causing instability is well compensated by Latarjet procedure which acts by triple blocking effect of the bone graft, the sling effect of the conjoint tendon of subscapularis and the ligament of the coracoacromial ligament stump. Materials and methods: Middle-aged patients with recurrent anterior shoulder dislocation and a mid-range instability on clinical assessment with an isolated glenoid bone loss of 20% or Bankart lesion with engaging Hill Sachs lesion were selected for the study. The surgical procedure included a subscapularis split to expose the glenoid. The coracoid graft harvested was prefixed with Kirschner wires and placed flush over the glenoid ensuring no medial or lateral overhang and fixed with 4.0mm cancellous screws with the washer. The functional outcome was measured with the ROWE score and ASES score and the movements were evaluated. Results: A total of 24 patients fulfilled the inclusion criteria. Post-operatively at final follow-up, the mean ROWE score was 97.08 ±8.45 and the mean ASES score was 94.4±9.10. One patient had screw breakage as a complication and another had restriction of movement which was managed with physiotherapy. Conclusion: Open Latarjet is an effective procedure for recurrent anterior shoulder instability in non-athletic middle-aged patients as a excellent functional outcome was achieved with this technique. We therefore recommend open Latarjet as an alternative to arthroscopic treatment in developing countries where patient affordability and the availability of the resources are the issues.

Background/Introduction
Nuclear scintigraphy with bone-avid radiotracers such as Tc-99m-PYP, Tc99m-DPC and Tc-99m-HMDP are used to diagnose transthyretin (ATTR) cardiac amyloidosis with limited quantification employing a semi-quantitative visual score and a heart to contralateral lung ratio. Therapy for ATTR cardiac amyloid currently is limited to a single FDA approved agent, tafamidis, however, there is no data regarding the longitudinal assessment of imaging findings in patients undergoing therapy. SPECT/CT acquisition and analysis with dedicated software can provide volumetric assessment and quantification of cardiac tracer uptake.
Purpose
The purpose of this study was to perform longitudinal assessment of cardiac ATTR amyloid 99mTc-PYP imaging findings to determine if treatment with tafamidis results in any change in quantitative measures of tracer uptake. There is no data on if treatment results in a decrease in cardiac amyloid burden as assessed by 99mTc-PYP imaging.
Methods
A prospective, single center, study of patients with ATTR cardiac amyloid being treated with tafamidis (either 80mg or 61mg dose) who have baseline and follow-up 99mTc-PYP studies. SPECT/CT quantification software was used to quantify heart, lung, and bone tracer uptake and generate standardized uptake values (SUVs). Comparison of baseline (before treatment) total SUVs, mean SUV value, percentage of the injected dose, mean SUV of heart to mean SUV of bone ratio and to mean SUV of right lung ratio was made to the values obtained at follow-up after tafamidis treatment. Measurements were obtained from the whole heart and the isolated left ventricle. Data was obtained by two physicians and the results averaged.
Results
5 patients were analyzed with a mean age 73.8 ± 7.7, 80% were males, and a mean length of tafamidis therapy at repeat imaging of 12.5 ± 3.8 months. At follow-up there was an average decrease in whole heart total SUV counts by -25.9 ± 10.3%, in the mean SUV value by -18.2 ± 18.2% and in the percentage of injected dose by -23.7 ± 14.0%. Similar decreases were seen in the isolated left ventricle measures. Heart to bone and heart to lung ratios showed a mixed response to therapy. Detailed results are provided in the table.
Conclusion
The measurements of total SUV counts, mean SUV value, and percentage of the injected dose showed improvement with tafamidis treatment. The ratios did not uniformly show improvement and the reason for this finding is unclear. This new technique offers a potential method for following tafamidis therapy and assessing the cardiac amyloid burden.

Abstract
Caries results in the demineralization and destruction of enamel and dentine, and as the disease progresses, irreversible pulpitis can occur. Vital pulp therapy (VPT) is directed towards pulp preservation and the prevention of the progression of inflammation. The outcomes of VPT are not always predictable, and there is often a poor correlation between clinical signs and symptoms, and the events occurring at a molecular level. The inflamed pulp expresses increased levels of cytokines, including tumour necrosis factor (TNF)-α, interleukin (IL)-1α, IL-1β, IL-4, IL-6, IL-8, IL-17 and IL-23, which recruit and drive a complex cellular immune response. Chronic inflammation and sustained cytokine release can result in irreversible pulp damage and a decreased capacity for tissue healing. Other chronic inflammatory diseases, such as psoriasis, inflammatory bowel diseases and rheumatoid arthritis, are also characterized by an dysregulated immune response composed of relatively high cytokine levels and increased numbers of immune cells along with microbial and hard-soft tissue destructive pathologies. Whilst anti-cytokine therapies have been successfully applied in the treatment of these diseases, this approach is yet to be attempted in cases of pulp inflammation. This review therefore focuses on the similarities in the aetiology between chronic inflammatory diseases and pulpitis, and explores how anti-cytokine therapies could be applied to manage an inflamed pulp and facilitate healing. Further proof-of-concept studies and clinical trials are justified to determine the effectiveness of these treatments to enable more predictable outcomes in VPT.
