Cost-effective Treatment Research Articles

Economic evaluation of stereotactic radiotherapy and stereotactic radiosurgery technologies in the treatment of cancers: a systematic review.

This systematic review study investigated the cost-effectiveness of stereotactic radiotherapy (SRT) and stereotactic radiosurgery (SRS) for treatment of various types of cancers. PubMed, Scopus, and Web of Science were searched from 30/12/1990 to 1/1/2023. The entered studies were screened in accordance with the inclusion criteria. The inclusion criteria encompassed all types of economic evaluation studies that investigated SRT/SRS technologies in the treatment of various cancers. A total of 47 articles were included in the review. The findings suggest that the use of Linear accelerator technology for the treatment of lung cancer (8 out of 12 studies) and prostate cancer (4 out of 5 studies) was a cost-effective strategy. Linear accelerator was found to be cost-effective in the treatment of liver metastases and liver cancer (2 out of 5 studies). All of the included studies that used Gamma Knife technology in brain metastases reported Gamma-Knife was a cost-effective treatment. Furthermore, in the treatment of prostate and liver cancer, proton therapy was identified as a cost-effective option than other treatments. This study confirms that SRT/SRS is a cost-effective procedure for the treatment of various types of cancers. Therefore, it is recommended to use SRT/SRS technology for optimal use of resources.

Environmental enrichment alleviates hyperalgesia by modulating central sensitization in a nitroglycerin-induced chronic migraine model of mice

BackgroundChronic migraine (CM) is a debilitating neurofunctional disorder primarily affecting females, characterized by central sensitization. Central sensitization refers to the enhanced response to sensory stimulation, which involves changes in neuronal excitability, synaptic plasticity, and neurotransmitter release. Environmental enrichment (EE) can increase the movement, exploration, socialization and other behaviors of mice. EE has shown promising effects in various neurological disorders, but its impact on CM and the underlying mechanism remains poorly understood. Therefore, the purpose of this study was to determine whether EE has the potential to serve as a cost-effective intervention strategy for CM.MethodsA mouse CM model was successfully established by repeated administration of nitroglycerin (NTG). We selected adult female mice around 8 weeks old, exposed them to EE for 2 months, and then induced the CM model. Nociceptive threshold tests were measured using Von Frey filaments and a hot plate. The expression of c-Fos, calcitonin gene-related peptide (CGRP) and inflammatory response were measured using WB and immunofluorescence to evaluate central sensitization. RNA sequencing was used to find differentially expressed genes and signaling pathways. Finally, the expression of the target differential gene was investigated.ResultsRepeated administration of NTG can induce hyperalgesia in female mice and increase the expression of c-Fos and CGRP in the trigeminal nucleus caudalis (TNC). Early exposure of mice to EE reduced NTG-induced hyperalgesia in CM mice. WB and immunofluorescence revealed that EE inhibited the overexpression of c-Fos and CGRP in the TNC of CM mice and alleviated the inflammatory response of microglia activation. RNA sequencing analysis identified that several central sensitization-related signaling pathways were altered by EE. VGluT1, a key gene involved in behavior, internal stimulus response, and ion channel activity, was found to be downregulated in mice exposed to EE.ConclusionEE can significantly ameliorate hyperalgesia in the NTG-induced CM model. The mechanisms may be to modulate central sensitization by reducing the expression of CGRP, attenuating the inflammatory response, and downregulating the expression of VGluT1, etc., suggesting that EE can serve as an effective preventive strategy for CM.

Acceptability of an Incentivized Peer Referral Intervention to Address COVID-19 Vaccine Hesitancy Among Adults in Yopougon-Est, Côte d'Ivoire.

Vaccine hesitancy persists as a barrier to vaccine uptake among adults across geographies. We pilot-tested an incentivized peer referral intervention in Yopougon-Est, Côte d'Ivoire, to encourage adults who recently received COVID-19 vaccination to discuss their experiences and motivate family and friends to seek vaccination. From May through June 2023, the intervention operated at 2 vaccination sites, where staff approached individuals immediately after receiving COVID-19 vaccination. Interested vaccine recipients received up to 9 referral coupons to distribute among their social circles, with a small financial incentive (approximately US$3) offered for each person they referred who returned to 1 of the 2 sites for COVID-19 vaccination. We collected data on numbers of people vaccinated and coupons returned. Qualitative interviews were conducted with 40 referred vaccine recipients and 7 public health officials. During the 6-week intervention, 450 newly vaccinated individuals were offered the opportunity to enroll, with 197 opting to distribute coupons. Nearly half (45%) of these peer mobilizers who distributed coupons referred at least 1 person who subsequently came in for vaccination, and most of this subset had 2 or more completed referrals. Qualitative findings revealed that coupons served as effective reminders, sparking discussions within social networks and prompting vaccine-seeking behavior. According to the referred vaccine recipients, hearing about their peers' vaccination experience influenced uptake. Vaccine recipients and public health officials found the small referral incentive acceptable. Officials noted the intervention's potential utility and cost effectiveness, suggesting possible sustainability. This incentivized peer referral intervention, capitalizing on peer networks and social norms, holds promise for increasing vaccine uptake in Yopougon-Est and potentially in other vaccination contexts globally. Practitioners can leverage the implementation guide and training materials we developed to replicate the intervention at larger scale and assess impact on vaccination trends.

Assessment of mothers’ satisfaction towards child vaccination service in South Omo zone, South Ethiopia region: a survey on clients’ perspective

BackgroundEven though childhood vaccination is a common and cost-effective public health intervention in preventing and reducing childhood disease and death, significant numbers of children do not complete vaccination within the first year of life. Studies indicated that user satisfaction influences service utilization and used as a key indicator of quality care. However, evidence on the level of mothers’ satisfaction with immunization service are limited in urban and accessible places and not well investigated among remote and pastoral communities. As such, this study aimed to address this gap and investigated mothers’ satisfaction towards child vaccination in a pastoralist and agrarian community of the South Omo zone in Southern region of Ethiopia.MethodsAn institution-based cross-sectional study was conducted among 1221 randomly selected mothers with children eligible for childhood vaccination using a structured, pretested, and interviewer-administered questionnaire. Maternal positive evaluations of the overall vaccination service were measured using 5-point Likert scale questions. Data were entered into Epi data version 3.5.1 and analyzed using IBM SPSS statistical package version 25. Exploratory factor analysis was used for Likert scale questions to extract factor scores which facilitate treatment of variables as continuous for further analysis. Bivariate and multivariable logistic regression analysis was employed to identify factors associated with the outcome variable. A P-value < 0.05 and adjusted odds ratio with 95% CI respectively were used to declare statistical significance and degree of association.ResultA total of 849 (69.53%) study participants were satisfied with the vaccination care provided for their children. Factors associated with mother’s satisfaction with child vaccination care include maternal age less than 30 years (AOR = 2.12; 95% CI = 1.61–2.79), infants age between 8 and 12 months (AOR = 1.83; 95% CI = 1.28, 2.62), not having history of adverse events following immunization (AOR = 1.57; 95% CI = 1.01–2.45), having 1 child under the age of 5 years (AOR = 1.34; 95% CI = 1.02–1.76), waiting 30 min or less to get the service (AOR = 1.39; 95% CI = 1.05–1.85), traveling 30 min or less to the vaccination center (AOR = 1.46; 95% CI = 1.08–1.98), having poor knowledge about the importance of vaccination (AOR = 1.51; 95% CI = 1.06–2.16), and having moderate knowledge about the importance of vaccination (AOR = 1.52; 95% CI = 1.06–2.18).ConclusionInterestingly, mothers’ satisfaction with their children’s vaccination service was relatively higher in a predominantly pastoral community compared with most of previous studies conducted in Ethiopia. Maternal and child age, number of children under the age of 5 years, history of adverse events following immunization, distance to the vaccination center, waiting time to get service and maternal knowledge were factors significantly associated with mothers’ satisfaction. Proactive measures with focus on increasing access to vaccination service, improving waiting time and raising awareness among mothers were recommended.

Mathematical modeling of two strains tuberculosis and COVID-19 vaccination model: a co-infection study with cost-effectiveness analysis

Tuberculosis and COVID-19 co-infection is currently the major issue of public health in many nations, including Ghana. Therefore, to explore the effects of the two Tuberculosis strains on COVID-19, we suggest a Tuberculosis and COVID-19 co-infection model. The study also provides the most economical and effective control methods to reduce the co-infection of tuberculosis and COVID-19. Based on the behavioral patterns of the two Tuberculosis strains and COVID-19 reproduction numbers, the stability of the co-infection model is examined. We explore the sensitivity of the parameters to examine the effect of the drug-resistant and drug-sensitive strain of Tuberculosis on the co-infection of COVID-19. We determine the most cost-effective and optimal treatment strategies that aim to maximize outcomes while minimizing tuberculosis and/or COVID-19 incidences, cost-effectiveness, and optimization approaches. The outcomes of this work contribute to a better understanding of Tuberculosis and COVID-19 epidemiology and provide insights into implementing interventions needed to minimize Tuberculosis and COVID-19 burden in similar settings worldwide.

Cost-effectiveness of restorative treatments for permanent molars with severe molar incisor hypomineralization: perspectives for the Brazilian public health system.

To undertake a cost-effectiveness analysis of restorative treatments for a first permanent molar with severe molar incisor hypomineralization from the perspective of the Brazilian public system. Two models were constructed: a one-year decision tree and a ten-year Markov model, each based on a hypothetical cohort of one thousand individuals through Monte Carlo simulation. Eight restorative strategies were evaluated: high viscosity glass ionomer cement (HVGIC);encapsulated GIC; etch and rinse adhesive + composite; self-etch adhesive + composite;preformed stainless steel crown; HVGIC + etch and rinse adhesive + composite; HVGIC + self-etch adhesive + composite, and encapsulated GIC + etch and rinse adhesive + composite. Effectiveness data were sourced from the literature. Micro-costing was applied using 2022 USD market averages with a 5% variation. Incremental cost-effectiveness ratio (ICER), net monetary benefit (%NMB), and the budgetary impact were obtained. Cost-effective treatments included HVGIC (%NMB = 0%/0%), encapsulated GIC (%NMB = 19.4%/ 19.7%), and encapsulated GIC + etch and rinse adhesive + composite (%NMB = 23.4%/ 24.5%) at 1year and 10years, respectively. The benefit gain of encapsulated GIC + etch and rinse adhesive + composite in relation to encapsulated GIC was small when compared to the cost increase at 1year (gain of 3.28% and increase of USD 24.26) and 10years (gain of 4% and increase of USD 15.54). Within the horizon and perspective analyzed, the most cost-effective treatment was encapsulated GIC restoration. This study can provide information for decision-making.

Optimizing the physical activity intervention for older adults with mild cognitive impairment: a factorial randomized trial

BackgroundPhysical activity (PA) intervention is one of the most effective interventions to promote cognitive function of older adults with mild cognitive impairment (MCI). However, the level of PA remains low. Based on the two core interventions (X-CircuiT and health education), this study aimed to examine the effect of three implementation strategies (viz., role modeling, goal-setting, and reminding) on the PA level among older adults with MCI using the multiphase optimization strategy (MOST).MethodsParticipants were randomized into one of eight conditions in a factorial design involving three factors with two levels: (i) role modeling (on vs. off); (ii) goal-setting (on vs. off); and (iii) reminding (on vs. off). The primary outcome was PA level at 12 weeks. The secondary outcomes were cognitive function, self-efficacy, and cost-effectiveness at 12 weeks. The intention-to-treat (ITT) analysis was performed as the main analysis and the per-protocol (PP) analysis as the sensitivity analysis.ResultsA total of 107 participants were included and randomly assigned into three groups, each receiving different implementation strategies. The results of the multivariate regression analysis showed that the three implementation strategies, namely, reminding (B = 0.31, p &amp;lt; 0.01), role modeling (B = 0.21, p &amp;lt; 0.01), and goal-setting (B = 0.19, p &amp;lt; 0.01), could significantly improve PA level. Specifically, it was found that role modeling (B = 0.68, p = 0.03) could significantly improve cognitive function. There were no significant interactions among the three implementation strategies. Role modeling was the most cost-effective strategy, costing 93.41 RMB for one unit of PA.ConclusionsRole modeling was likely to be the best implementation strategy. The value-based and cost-effective PA intervention package could include the core intervention (X-CircuiT and health education) and implementation strategy (role modeling).Clinical Trial Registrationhttps://www.chictr.org.cn, The study was retrospectively registered on 30 June 2022 (ChiCTR2200061693).

Effects of Laghoo Shankaprakshalana (yogic colon cleansing) on anthropometric measurements in obese individuals.

Obesity is considered as one of the major public health burden and it is predictor of cardiovascular risk factor. Yoga is a mind-body medicine helps to promote health. This study was aimed to explore whether Laghoo Shankaprashalana (LS) reduce the body weight in obese individuals. This was a single group pre-post study. A total of 40 subjects (9 Male, 31 Female) aged between 18 and 40 years were recruited. This study was conducted in government yoga and naturopathy medical college, Chennai. Subjects were practiced weekly once LS for eight weeks (eight sessions). Subjects were assessed pre and post on body weight, body mass index, waist circumference, hip circumference, waist hip ratio, pulse rate and blood pressure. Variables were analyzed using Paired sample t test except waist hip ratio, which were analyzed using Wilcoxon's signed ranks test. There was significant reduction in the body weight (p<0.001, 5.81 %), Body Mass Index (p<0.001, 5.88 %), Waist Circumference (p<0.001, 7.20 %), Hip Circumference (p<0.001, 5.04 %), and Waist Hip Circumference (p<0.001, 3.19 %) after LS. However, there was no statistical significance difference in pulse rate, blood pressure. Eight sessions of Laghoo Shankaprakshalana helps to reduces body weight, body mass index, waist circumference, hip circumference and waist hip ratio. Reduction in the waist circumference might helps to reduce the cardiovascular risk. LS may be one of the cost effective intervention that can be incorporated in the weight loss regimen.

Analyzing the Benefits and Costs of the Safe Step Act on Patients, Physicians, and Insurers

Pharmaceutical expenditures in the United States, particularly in dermatology, have grown rapidly, driven by expensive topical and biologic treatments. Insurers are employing cost-containing strategies such as step therapy, which mandates the use of lower-cost treatments before more expensive medications. The bipartisan Safe Step Act aims to enhance step therapy policies by introducing a transparent process for requesting exceptions and reasonable timelines for the process. However, there is limited analysis on how the Safe Step Act would affect the healthcare environment. We examine the policies of the Safe Step Act and existing literature on prior authorizations and discuss how the bill could affect patients, physicians, and insurers. While the act could expedite access to necessary medications and prevent irreversible harm to patients from delaying efficacious treatment, it falls short in relieving the administrative burdens on dermatology clinics. Although there is no ideal solution for managing healthcare costs, measures like step therapy encourage cost-effective treatments and optimizing care for the population. Curtailing step therapy with the exemptions process of the Safe Step Act might streamline patient access to treatments but could impede cost-containment strategies, weaken the bargaining power of insurers, and result in higher insurance premiums.

Successful Intentional Replantation of a Severely Compromised Tooth Using 3 Types of Phototherapy: A Case Report.

Background: Intentional replantation (IR) is an emerging and cost-effective last-resort treatment for persistent apical periodontitis. Adjunctive phototherapy for IR aims to improve the management of challenging cases by enhancing disinfection, stimulating healing and promoting regeneration. Objective: We report a novel phototherapy-assisted IR protocol conducted on a compromised lateral incisor with an extensive periapical infection (Ø > 10 mm) in a 68-year-old diabetic male. Methods: The IR protocol involved pre- and postoperative photobiomodulation (660 nm, 0.2 J/cm2, 60 sec/site), antimicrobial photodynamic therapy of the root surface (660 nm, 0.6 J/cm2, 30 sec, methylene blue photosensitizer), and Er:YAG root and socket debridement (2940 nm, 21 J/cm2, 30 sec). The total time from extraction to replantation was 14 min 35 sec. Results: The tooth at 3.5-year follow-up remained clinically functional with radiographic resolution of the infection indicating a successful reimplantation. Conclusions: This case report demonstrated that an adjunctive phototherapy IR protocol can effectively treat a compromised tooth with extensive periapical infection.

Epidemiological and health economic implications of symptom propagation in respiratory pathogens: A mathematical modelling investigation.

Respiratory pathogens inflict a substantial burden on public health and the economy. Although the severity of symptoms caused by these pathogens can vary from asymptomatic to fatal, the factors that determine symptom severity are not fully understood. Correlations in symptoms between infector-infectee pairs, for which evidence is accumulating, can generate large-scale clusters of severe infections that could be devastating to those most at risk, whilst also conceivably leading to chains of mild or asymptomatic infections that generate widespread immunity with minimal cost to public health. Although this effect could be harnessed to amplify the impact of interventions that reduce symptom severity, the mechanistic representation of symptom propagation within mathematical and health economic modelling of respiratory diseases is understudied. We propose a novel framework for incorporating different levels of symptom propagation into models of infectious disease transmission via a single parameter, α. Varying α tunes the model from having no symptom propagation (α = 0, as typically assumed) to one where symptoms always propagate (α = 1). For parameters corresponding to three respiratory pathogens-seasonal influenza, pandemic influenza and SARS-CoV-2-we explored how symptom propagation impacted the relative epidemiological and health-economic performance of three interventions, conceptualised as vaccines with different actions: symptom-attenuating (labelled SA), infection-blocking (IB) and infection-blocking admitting only mild breakthrough infections (IB_MB). In the absence of interventions, with fixed underlying epidemiological parameters, stronger symptom propagation increased the proportion of cases that were severe. For SA and IB_MB, interventions were more effective at reducing prevalence (all infections and severe cases) for higher strengths of symptom propagation. For IB, symptom propagation had no impact on effectiveness, and for seasonal influenza this intervention type was more effective than SA at reducing severe infections for all strengths of symptom propagation. For pandemic influenza and SARS-CoV-2, at low intervention uptake, SA was more effective than IB for all levels of symptom propagation; for high uptake, SA only became more effective under strong symptom propagation. Health economic assessments found that, for SA-type interventions, the amount one could spend on control whilst maintaining a cost-effective intervention (termed threshold unit intervention cost) was very sensitive to the strength of symptom propagation. Overall, the preferred intervention type depended on the combination of the strength of symptom propagation and uptake. Given the importance of determining robust public health responses, we highlight the need to gather further data on symptom propagation, with our modelling framework acting as a template for future analysis.

Economic evaluation of Be a Mom, a web-based intervention to prevent postpartum depression in high-risk women alongside a randomized controlled trial

BackgroundPostpartum depression (PPD) poses significant challenges, affecting both mothers and children, with substantial societal and economic implications. Internet-based cognitive behavioral therapy interventions (iCBT) offer promise in addressing PPD, but their economic impact remains unexplored. This study aimed to evaluate the cost-utility of Be a Mom, a self-guided iCBT intervention, compared with a waiting-list control among postpartum women at high risk of PPD. MethodsThis economic evaluation was conducted alongside a 14-month randomized controlled trial adopting a societal perspective. Participants were randomized to Be a Mom (n = 542) or a waitlisted control group (n = 511). Self-report data on healthcare utilization, productivity losses, and quality-adjusted life years (QALYs) were collected at baseline, post-intervention, and 4 and 12 months post-intervention. Incremental cost-effectiveness ratios (ICERs) were calculated, and cost-effectiveness acceptability curves were generated using nonparametric bootstrapping. Sensitivity analyses were conducted to assess result robustness. ResultsOver 14 months, Be a Mom generated a QALY gain of 0.0184 (0.0022, 0.0346), and cost savings of EUR 34.06 (−176.16, 108.04) compared to the control group. At a willingness to pay of EUR 20,000, Be a Mom had a 97.6 % probability of cost-effectiveness. LimitationsResults have limitations due to self-selected sample, potential recall bias in self-reporting, missing data, limited follow-up, and the use of a waiting-list control group. ConclusionsThis study addresses a critical gap by providing evidence on the cost-utility of an iCBT intervention tailored for PPD prevention. Further research is essential to identify scalable and cost-effective interventions for reducing the burden of PPD.

Impact and cost-effectiveness of the 6-month BPaLM regimen for rifampicin-resistant tuberculosis in Moldova: A mathematical modeling analysis.

Emerging evidence suggests that shortened, simplified treatment regimens for rifampicin-resistant tuberculosis (RR-TB) can achieve comparable end-of-treatment (EOT) outcomes to longer regimens. We compared a 6-month regimen containing bedaquiline, pretomanid, linezolid, and moxifloxacin (BPaLM) to a standard of care strategy using a 9- or 18-month regimen depending on whether fluoroquinolone resistance (FQ-R) was detected on drug susceptibility testing (DST). The primary objective was to determine whether 6 months of BPaLM is a cost-effective treatment strategy for RR-TB. We used genomic and demographic data to parameterize a mathematical model estimating long-term health outcomes measured in quality-adjusted life years (QALYs) and lifetime costs in 2022 USD ($) for each treatment strategy for patients 15 years and older diagnosed with pulmonary RR-TB in Moldova, a country with a high burden of TB drug resistance. For each individual, we simulated the natural history of TB and associated treatment outcomes, as well as the process of acquiring resistance to each of 12 anti-TB drugs. Compared to the standard of care, 6 months of BPaLM was cost-effective. This strategy was estimated to reduce lifetime costs by $3,366 (95% UI: [1,465, 5,742] p < 0.001) per individual, with a nonsignificant change in QALYs (-0.06; 95% UI: [-0.49, 0.032] p = 0.790). For those stopping moxifloxacin under the BPaLM regimen, continuing with BPaL plus clofazimine (BPaLC) provided more QALYs at lower cost than continuing with BPaL alone. Strategies based on 6 months of BPaLM had at least a 93% chance of being cost-effective, so long as BPaLC was continued in the event of stopping moxifloxacin. BPaLM for 6 months also reduced the average time spent with TB resistant to amikacin, bedaquiline, clofazimine, cycloserine, moxifloxacin, and pyrazinamide, while it increased the average time spent with TB resistant to delamanid and pretomanid. Sensitivity analyses showed 6 months of BPaLM to be cost-effective across a broad range of values for the relative effectiveness of BPaLM, and the proportion of the cohort with FQ-R. Compared to the standard of care, 6 months of BPaLM would be expected to save Moldova's national TB program budget $7.1 million (95% UI: [1.3 million, 15.4 million] p = 0.002) over the 5-year period from implementation. Our analysis did not account for all possible interactions between specific drugs with regard to treatment outcomes, resistance acquisition, or the consequences of specific types of severe adverse events, nor did we model how the intervention may affect TB transmission dynamics. Compared to standard of care, longer regimens, the implementation of the 6-month BPaLM regimen could improve the cost-effectiveness of care for individuals diagnosed with RR-TB, particularly in settings with a high burden of drug-resistant TB. Further research may be warranted to explore the impact and cost-effectiveness of shorter RR-TB regimens across settings with varied drug-resistant TB burdens and national income levels.

Xuanfei Formula inhibited RSV infection by normalizing the SREBP2-mediated cholesterol synthesis process

Background and aimsRespiratory syncytial virus (RSV) is the major cause of lower respiratory tract infections in children and the elderly, often progressing to pneumonia and severe sequelae. However, there are currently no feasible and cost-effective interventions with proven efficacy for children, making medications with anti-RSV activity urgently needed. Traditional Chinese medicine has shown promising therapeutic efficacy in alleviating viral infection symptoms. Therefore, we aimed to develop effective strategies for RSV treatment based on traditional Chinese medicine.Methods and resultsThe infection status was assessed in BALB/c mice with or without Xuanfei Formula (XFF) treatment over a one-week period using H&amp;amp;E staining, cytokine assays and RSV titer testing after RSV challenge. Remarkably, on the first day of XFF intervention, both the pro-inflammation cytokine levels in the serum and RSV-N gene copies in the lung of mice were plummeted, compared to the RSV-infected group. This implied that XFF might possess the immune-independent anti-RSV capability. To elucidate the underlying mechanism, we employed transcriptome analysis followed by k-means analysis. The reversal effects of XFF against RSV primarily focused on the processes of innate and adaptive immunity. Additionally, we found that XFF administration corrected the disordered fatty acid and cholesterol metabolism processes during RSV infection. Lipidomics profiling indicated consistent cholesterol abundance with transcriptional changes but not fatty acids. Cholesterol synthesis-related genes mRNA levels and cholesterol synthesis intermediates detection supported XFF’s repression upon cholesterol biosynthesis. Aberrantly increased cholesterol production has been reported as necessary for RSV infection. To mimic that, we observed lovastatin treatment inhibited RSV replication and pro-inflammation cytokine expression in vitro. Transcription factor prediction of differentially expressed genes (DEGs) involved in cholesterol synthesis implicated SREBP2. Through network pharmacology, stigmasterol and β-sitosterol were identified as the effective active ingredients within the XFF, with the help of further molecular docking and mass spectrum detection. In vitro experiments demonstrated β-sitosterol and stigmasterol reinforced the bonding between SREBP cleavage-activation protein (SCAP) and insulin-induced gene proteins (INSIGs) to inhibit SREBP2 cleavage maturation and consequent RSV infection.ConclusionXuanfei Formula (XFF) exhibits excellent anti-RSV efficacy by inhibiting SREBP2-mediated cholesterol synthesis to reduce RSV replication and ameliorate inflammation in the lung of infected mice.

The economic burden of multimorbidity: Protocol for a systematic review.

Multimorbidity, also known as multiple long-term conditions, leads to higher healthcare utilisation, including hospitalisation, readmission, and polypharmacy, as well as a financial burden to families, society, and nations. Despite some progress, the economic burden of multimorbidity remains poorly understood. This paper outlines a protocol for a systematic review that aims to identify and synthesise comprehensive evidence on the economic burden of multimorbidity, considering various definitions and measurements of multimorbidity, including their implications for future cost-of-illness analyses. The review will include studies involving people of all ages with multimorbidity without any restriction on location and setting. Cost-of-illness studies or studies that examined economic burden including model-based studies will be included, and economic evaluation studies will be excluded. Databases including Scopus (that includes PubMed/MEDLINE), Web of Science, CINAHL Plus, PsycINFO, NHS EED (including the HTA database), and the Cost-Effectiveness Analysis Registry, will be searched until March 2024. The risk of bias within included studies will be independently assessed by two authors using appropriate checklists. A narrative synthesis of the main characteristics and results, by definitions and measurements of multimorbidity, will be conducted. The total economic burden of multimorbidity will be reported as mean annual costs per patient and disaggregated based on counts of diseases, disease clusters, and weighted indices. The results of this review will provide valuable insights for researchers into the key cost components and areas that require further investigation in order to improve the rigour of future studies on the economic burden of multimorbidity. Additionally, these findings will broaden our understanding of the economic impact of multimorbidity, inform us about the costs of inaction, and guide decision-making regarding resource allocation and cost-effective interventions. The systematic review's results will be submitted to a peer-reviewed journal, presented at conferences, and shared via an online webinar for discussion.

BRIDGING THE GAP BETWEEN PRIMARY AND SECONDARY CARE POST-HIP FRACTURE WITH A NOVEL PATIENT ADVOCATE ROLE

Within an ageing population, the morbidity and mortality burden of neck of femur fractures will only worsen. Financially incentivising acute Trusts via the Best Practice Tariff for inpatient care has yielded good results(1,2,3,4) but post-discharge care is still variable. Most importantly, restoring patients to their pre-fracture mobility is key to their quality of life(5,6) and reducing both readmissions to hospital(7,8) and expensive local authority residential care. Unfortunately, physiotherapist vacancies are in their thousands(9,10) leading to waiting times of around three months once discharged(11).In 2019, the Royal Derby Hospital created a novel Hip Fracture Patient Advocate (HFPA) to observe those who have fallen through gaps in community services. It involves monitoring patients’ progression, signposting to appropriate services, flagging issues to the responsible consultant and assisting in physical mobilisation.A retrospective review examined data from patients discharged to their own homes. This included demographics, residential status and mobility, both pre-fracture and at 120 days post-fracture. Mobility was classified into five categories, in line with the national hip fracture database.In 2018, of 238 patients, 41.2% returned to their baseline or increased mobility, and, after the introduction of the HFPA in 2019, this figure increased to 48.2%.In one year, there was a 7% increase in patients recovering their baseline mobility. This is a cost-effective intervention that can successfully improve mobility, leading to improved long-term outcomes. This includes the potential to reduce acute readmissions and the need for residential care, appealing to Integrated Care Boards. It also bridges the gap to primary care to optimise medical management and after further development, could be financially-incentivised via the Best Practice Tariff. Rather than thinking more expensive clinicians are required, this study proposes that a HFPA can garner better outcomes for both the patient and the wider system.

Concurrent congenital hemophilia B and acquired hemophilia A: a unique case report.

Congenital hemophilia B is a rare X-linked recessive bleeding disorder caused by factor IX deficiency. Acquired hemophilia A is a rare, acquired bleeding disorder that presents with new-onset bleeding, especially in older adults, due to the development of auto-antibodies against factor VIII (FVIII). This case report presents the medical management of a patient with congenital hemophilia B and acquired hemophilia A. We highlight the limitations of maintaining factor levels with factor replacement therapy alone, particularly in hemophilia patients who have developed factor inhibitors. In addition, we draw attention to the need for dose escalation, the cost, and the need for immune-tolerance induction therapy. This case illustrates that when the current diagnosis does not explain the full clinical picture and laboratory data are inadequate, it is important to continue to seek alternative diagnoses and cost-effective treatment.

Clinicopathological profile of head and neck cancers in Army Hospital of Nepal: a retrospective study.

Head and neck cancer is common in several parts of the world. It is sixth most prevalent neoplasms in the world. Approximately 900000 cases diagnosed worldwide per year. It has good prognosis when timely diagnosed and treated appropriately. This was a retrospective study carried out in the Department of ENT-HNS of Shree Birendra Hospital, Chhauni, Kathmandu from May 2022 to April 2023. All histopathologically proven malignant cases of head and neck region were included in the study. Data were entered in Microsoft excel and managed in SPSS version 22. Analysis was done in the form of percentage and proportion and represented as table where necessary. The study has been registerd in clinical trials and has been reported in line with the STROCSS criteria. Total 76 patients were analyzed. Age ranged from 17 to 84 years and the most common age group presenting with head and neck cancer was 61-80 years. The most common malignancy was laryngeal cancer (34%) followed by thyroid malignancies (29%). Squamous cell carcinoma was the commonest histological type (48%). Surgery with postoperative radiotherapy (RT)/radioactive iodine (RAI) was found to be the commonest treatment modality. Head and neck cancers are not uncommon and majority of patients present late with advanced stage cancer. Hence, public awareness, early diagnosis with cost-effective treatment and regular follow-up are needed to improve outcomes of these patients in our society.

Physical Exercise to Redynamize Interoception in Substance use Disorders.

Physical exercise is considered a promising medication-free and cost-effective adjunct treatment for substance use disorders (SUD). Nevertheless, evidence regarding the effectiveness of these interventions is currently limited, thereby signaling the need to better understand the mechanisms underlying their impact on SUD, in order to reframe and optimize them. Here we advance that physical exercise could be re-conceptualized as an "interoception booster", namely as a way to help people with SUD to better decode and interpret bodily-related signals associated with transient states of homeostatic imbalances that usually trigger consumption. We first discuss how mismatches between current and desired bodily states influence the formation of reward-seeking states in SUD, in light of the insular cortex brain networks. Next, we detail effort perception during physical exercise and discuss how it can be used as a relevant framework for re-dynamizing interoception in SUD. We conclude by providing perspectives and methodological considerations for applying the proposed approach to mixed-design neurocognitive research on SUD.

Facile one-pot synthesis of ternary Fe doped Cu-ZnO nanocatalyst: An efficient and recyclable solar light driven photocatalyst

Currently, nanoparticles are regarded as excellent materials for degrading and removing dyes due to their beneficial surface features and chemical reactivity. Herein, Cu doped ZnO (CZ) was co-doped with Fe (FCZ) at different concentrations (2, 3, 4 and 8 wt% with respect to CZ) via simple one-step co-precipitation approach. The structural, surface morphology, surface properties, optical and photocatalytic performance of prepared samples were studied. Due to the doping of Fe, the band gap of CZ reduced from 2.7 eV to 2.29 eV, which is beneficial for absorbing visible light. Among doped CZs, 4 wt% Fe-doped CZ (4FCZ) exhibited 97.1% methylene blue (MB) degradation at neutral pH under 60 min of sunlight exposure. Furthermore, the effect of initial concentration of dye, catalyst load, and pH on the degradation process was investigated. The remarkable photocatalytic activity of 4FCZ nanoparticles can be attributed to their advantageous surface properties, such as their high specific surface area, heterostructure morphology, and mesoporous nature. Scavenger study identified •O−2, e−, and h+ as main reactive species. Pseudo-first order kinetics revealed degradation order: 4FCZ>8FCZ>3FCZ>2FCZ>CZ. 4FCZ showed recyclability with 90.9% MB degradation after three cycles. Mineralization of MB was analysed by COD and LC-MS studies. Fe-doped CZ emerges as a promising, cost-effective wastewater treatment under sunlight without special equipment. This study provides new insights on synthesis of ternary nanocatalyst for dye degradation.
