TRPV4 neuromuscular disease registry highlights bulbar, skeletal and proximal limb manifestations.

Dominant missense mutations of the calcium-permeable cation channel TRPV4 cause Charcot-Marie-Tooth disease (CMT) type 2C and two forms of distal spinal muscular atrophy. These conditions are collectively referred to as TRPV4-related neuromuscular disease and share features of motor greater than sensory dysfunction and frequent vocal fold weakness. Pathogenic variants lead to gain of ion channel function that can be rescued by TRPV4 antagonists in cellular and animal models. As small molecule TRPV4 antagonists have proven safe in trials for other disease indications, channel inhibition is a promising therapeutic strategy for TRPV4 patients. However, the current knowledge of the clinical features and natural history of TRPV4-related neuromuscular disease is insufficient to enable rational clinical trial design. To address these issues, we developed a TRPV4 patient database and administered a TRPV4-specific patient questionnaire. Here, we report demographic and clinical information, including CMT examination scores (CMTES), from 68 patients with known pathogenic TRPV4 variants, 40 of whom also completed the TRPV4 patient questionnaire. TRPV4 patients showed a bimodal age of onset, with the largest peak occurring in the first 2 years of life. Compared to CMT1A patients, TRPV4 patients showed distinct symptoms and signs, manifesting more ambulatory difficulties and more frequent involvement of proximal arm and leg muscles. Although patients reported fewer sensory symptoms, sensory dysfunction was often detected clinically. Many patients were affected by vocal fold weakness (55%) and shortness of breath (55%), and 11% required ventilatory support. Skeletal abnormalities were common, including scoliosis (64%), arthrogryposis (33%), and foot deformities. Strikingly, patients with infantile onset of disease showed less sensory involvement and less progression of symptoms. These results highlight distinctive clinical features in TRPV4 patients, including motor-predominant disease, proximal arm and leg weakness, severe ambulatory difficulties, vocal fold weakness, respiratory dysfunction, and skeletal involvement. In addition, patients with infantile onset of disease appeared to have a distinct phenotype with less apparent disease progression based on CMTES. These collective observations indicate that clinical trial design for TRPV4-related neuromuscular disease should include outcome measures that reliably capture non-length dependent motor dysfunction, vocal fold weakness, and respiratory disease.

Combined clinical, structural, and cellular studies discriminate pathogenic and benign TRPV4 variants.

Dominant mutations in the calcium-permeable ion channel TRPV4 (transient receptor potential vanilloid 4) cause diverse and largely distinct channelopathies, including inherited forms of neuromuscular disease, skeletal dysplasias, and arthropathy. Pathogenic TRPV4 mutations cause gain of ion channel function and toxicity that can be rescued by small molecule TRPV4 antagonists in cellular and animal models, suggesting that TRPV4 antagonism could be therapeutic for patients. Numerous variants in TRPV4 have been detected with targeted and whole exome/genome sequencing, but for the vast majority, their pathogenicity remains unclear. Here, we used a combination of clinical information and experimental structure-function analyses to evaluate 30 TRPV4 variants across various functional protein domains. We report clinical features of seven patients with TRPV4 variants of unknown significance and provide extensive functional characterization of these and an additional 17 variants, including structural position, ion channel function, subcellular localization, expression level, cytotoxicity, and protein-protein interactions. We find that gain-of-function mutations within the TRPV4 intracellular ankyrin repeat domain target charged amino acid residues important for RhoA interaction, whereas ankyrin repeat domain residues outside of the RhoA interface have normal or reduced ion channel activity. We further identify a cluster of gain-of-function variants within the intracellular intrinsically disordered region that may cause toxicity via altered interactions with membrane lipids. In contrast, assessed variants in the transmembrane domain and other regions of the intrinsically disordered region do not cause gain of function and are likely benign. Clinical features associated with gain of function and cytotoxicity include congenital onset of disease, vocal cord weakness, and motor predominant disease, whereas patients with likely benign variants often demonstrated late-onset and sensory-predominant disease. These results provide a framework for assessing additional TRPV4 variants with respect to likely pathogenicity, which will yield critical information to inform patient selection for future clinical trials for TRPV4 channelopathies.

Cardiolipin metabolism regulates expression of muscle transcription factor MyoD1 and muscle development.

The mitochondrial phospholipid cardiolipin (CL) is critical for numerous essential biological processes, including mitochondrial dynamics and energy metabolism. Mutations in the CL remodeling enzyme TAFAZZIN cause Barth syndrome, a life-threatening genetic disorder that results in severe physiological defects, including cardiomyopathy, skeletal myopathy, and neutropenia. To study the molecular mechanisms whereby CL deficiency leads to skeletal myopathy, we carried out transcriptomic analysis of the TAFAZZIN-knockout (TAZ-KO) mouse myoblast C2C12 cell line. Our data indicated that cardiac and muscle development pathways are highly decreased in TAZ-KO cells, consistent with a previous report of defective myogenesis in this cell line. Interestingly, the muscle transcription factor myoblast determination protein 1 (MyoD1) is significantly repressed in TAZ-KO cells and TAZ-KO mouse hearts. Exogenous expression of MyoD1 rescued the myogenesis defects previously observed in TAZ-KO cells. Our data suggest that MyoD1 repression is caused by upregulation of the MyoD1 negative regulator, homeobox protein Mohawk, and decreased Wnt signaling. Our findings reveal, for the first time, that CL metabolism regulates muscle differentiation through MyoD1 and identify the mechanism whereby MyoD1 is repressed in CL-deficient cells.

Telepharmacy: A Systematic Review of Field Application, Benefits, Limitations, and Applicability During the COVID-19 Pandemic.

Introduction: Telepharmacy is widely known as the delivery of pharmacy care offered by registered pharmacists and pharmacies using telecommunication technologies to patients at a distance. We conducted a systematic review of the reported usages, benefits, and limitations of telepharmacy models worldwide to further clarify the pros and cons of a telepharmacy model. Methods: A total of 39 relevant articles was included after searching for articles with a fixed term on four databases, including PubMed, Virtual Health Library (VHL), Global Health Library (GHL), and Google Scholar, as of April 2021. Results: Our review suggested that telepharmacy has played an essential role in addressing pharmacist shortages and helping patients both safely and effectively administer medications in underserved areas. During the COVID-19 pandemic, remote dispensing and counseling are effective measures to avoid infection. Conclusion: Telepharmacy could potentially replace or complement pharmaceutical-related activities, facilitating future innovation in the health care industry.

Enhancement of Edwardsiella piscicida infection, biofilm formation, and motility caused by N-acetylneuraminate lyase.

Sialic acid and its catabolism are involved in bacterial pathogenicity. N-acetylneuraminate lyase (NAL), which catalyzes the reversible aldol cleavage of sialic acid to form N-acetyl-D-mannosamine in the first step of sialic acid degradation, has been recently investigated to elucidate whether NAL enhances bacterial virulence; however, the role of NAL in bacterial pathogenicity remains unclear. In the present study, we demonstrated that the existence of two enzymes in Edwardsiella piscicida, referred to as dihydrodipicolinate synthase (DHDPS) and NAL, induced the cleavage/condensation activity toward sialic acids such as N-acetylneuraminic acid, N-glycolylneuraminic acid and 3-deoxy-D-glycero-D-galacto-non-2-ulopyranosonic acid. NAL enhanced cellular infection in vitro and suppressed the survival rate in zebrafish larvae in bath-infection in vivo, whereas DHDPS did not. Furthermore, NAL strongly activated the expression of E. piscicida phenotypes such as biofilm formation and motility, whereas DHDPS did not. Besides, the gene expression level of nanK, nanE, and glmU were up-regulated in the NAL-overexpressing strain, along with an increase in the total amount of N-acetylglucosamine.

Host lactosylceramide enhances Edwardsiella tarda infection.

Edwardsiella tarda is a Gram-negative bacterium causing economic damage in aquaculture. The interaction of E. tarda with microdomains is an important step in the invasion, but the target molecules in microdomains remain undefined. Here, we found that intraperitoneal injection of E. tarda altered splenic glycosphingolipid patterns in the model host medaka (Oryzias latipes) accompanied by alteration of glycosphingolipid metabolism-related gene expressions, suggesting that glycosphingolipid levels are involved in E. tarda infection. To ascertain the significance of glycosphingolipids in the infection, fish cell lines, DIT29 cells with a high amount of lactosylceramide (LacCer) and glucosylceramide (GlcCer), and GAKS cells with a low amount of these lipids, were treated with methyl-ß-cyclodextrin to disrupt the microdomain. E. tarda infection was suppressed in DIT29 cells, but not in GAKS cells, suggesting the involvement of microdomain LacCer and GlcCer in the infection. DL-threo-1-phenyl-2-palmitoylamino-3-morpholino-1-propanol, an inhibitor of glycosphingolipid-synthesis, attenuated the infection in DIT29 cells, while Neu3-overexpressing GAKS cells, which accumulated LacCer, enhanced the infection. E. tarda possessed binding ability towards LacCer, but not GlcCer, and LacCer preincubation declined the infection towards fish cells, possibly due to the masking of binding sites. The present study suggests that LacCer may be a positive regulator of E. tarda invasion.

Involvement of N-acetylneuraminate cytidylyltransferase in Edwardsiella piscicida pathogenicity.

Edwardsiella piscicida is a gram-negative bacterium that causes Edwardsiellosis in cultured fish. Edwardsiellosis is accompanied by symptoms such as skin lesions, hemorrhage, and necrosis in fish organs, which leads to significant economic losses in the aquaculture industry. Recently, we found that bacterial sialoglycoconjugates may be involved in the infectivity of E. piscicida. The more infectious strains of E. piscicida contain more sialic acid in the bacterial body, and the mRNA level of putative CMP-Neu5Ac synthase (css) is upregulated compared to that in the non-pathogenic strain. However, this putative css gene is yet to be cloned, and the involvement of CSS in E. piscicida pathogenicity remains unclear. Here, we cloned and transferred the css gene from E. piscicida into the FPC498 strain. CSS promoted infection in cultured cells originating from different fish species, and enhanced the mortality of E. piscicida-infected zebrafish larvae. CSS enhanced cell attachment and motility in E. piscicida, which differs from the decreased bacterial growth observed with the sialic acid-supplemented M9 medium. Both fractions (chloroform-methanol)-soluble and -insoluble fraction) prepared from E. piscicida pellet exhibited the increment of sialo-conjugates induced by CSS. Further, lectin blotting revealed the increment of Sia α2-3- and α2-6-, but not α2-8-, -linked glycoprotein in CSS-overexpressing E. piscicida. Overall, these findings indicate the physiological significance of CSS and the role of sialylation in E. piscicida pathogenicity.

Correlation between anti-malarial and anti-haemozoin activities of anti-malarial compounds.

BACKGROUND: Despite noticeable improvement in anti-malarial treatment, rapid growth of resistant malaria strains points out the need for continuous development of novel anti-malarials to fight the disastrous infection. Haemozoin is considered as a novel inhibitory pathway for new anti-malarial drugs, therefore, this study aimed to systematically review all articles investigating the correlation between anti-malarial and anti-haemozoin activities of anti-malarial compounds. METHODS: A literature search was conducted on 22 October 2017 in eight databases for relevant in vitro articles reporting the correlation between anti-malarial and anti-haemozoin of anti-malarial compounds, based on the constructed search terms and inclusion criteria. ToxRtool was used to assess quality of each study. RESULTS: A total of ten articles were included in the review. In vitro anti-malarial and anti-haemozoin activity had a good correlation for quinolines for sensitive strains (R2 ranging from 0.66 to 0.95) and xanthones (Spearman ρ = 0.886). However, these correlations were reached after removing some compounds which had non-detectable anti-malarial or anti-haemozoin effects. Other structures (acridines, pyrolidines) showed negligible correlation with Spearman ρ ranging from 0.095 to 0.381 for acridines, and r varying from 0.54 to 0.62 for pyrolidines. Some good correlations were only shown in a logarithmic manner or when the anti-malarial activity was normalized. CONCLUSION: The results raised a relative relationship between anti-haemozoin and in vitro anti-malarial activities. Some studies reported compounds that were effective in the inhibition of haemozoin formation, but failed to inhibit the parasite survival and vice versa. The correlation results in these studies were calculated after these compounds were removed from their analysis. The ability of anti-malarial compounds to accumulate inside the reaction site might strengthen their anti-malarial activity.

Desialylation by Edwardsiella tarda is the initial step in the regulation of its invasiveness.

Edwardsiella tarda is a gram-negative bacterium causing significant economic losses to aquaculture. E. tarda possesses NanA sialidase which removes sialic acids from α2-3 sialo-glycoprotein of host cells. However, the relationship between NanA sialidase activity and E. tarda invasiveness remains poorly understood. Furthermore, the pathway of sialic acid metabolism in E. tarda remains to be elucidated. We studied sialidase activity in several E. tarda strains and found that the pathogenic strains exhibited higher sialidase activity and greater up-regulation of the NanA mRNA level than non-pathogenic strain. Pathogenic strains also showed higher rates of infection in GAKS cells, and the infection was drastically suppressed by sialidase inhibitor. Additionally, NanA gene overexpression significantly increased infection and treatment of E. tarda with free sialic acid enhanced the rate of infection in GAKS cells. Sialic acid treatment enhanced mRNA levels of two N-acetylneuraminate lyases and one N-acetylneuraminate cytidylyltransferase. E. tarda uses sialic acid as a carbon source for growth via N-acetylneuraminate lyases. The strains with high N-acetylneuraminate cytidylyltransferase level showed greater sialylation of the lipopolysaccharides and glycoproteins. Our study establishes the significance of desialylation by E. tarda sialidase in the regulation of its invasiveness.

Diversion and phylogenetic relatedness of filterable bacteria from Norwegian tap and bottled waters.

Numerous articles have documented the existence of filterable bacteria. Where filtration is the chosen method of sterilization for medicinal or media components, these bacteria will by definition render products non-sterile. They may further represent a health hazard to the end user. A wide-range of bacterial genera were found in bottled and tap water filtrates from 0.2 µm filters, including genera housing opportunistic pathogens (e.g. Methylobacterium) and endospore formers (Paenibacillus). Two municipal tap water isolates were only distantly related to named species. One of these grew on agar, and could potentially provide hitherto unharvested useful biological products. The other grew only in water, and failed to produce colonies on media targeting either heterotrophs or autotrophs. The present study is one of very few looking at filterable bacteria in bottled waters intended for human consumption and the first identifying the filterable portion. It extends the range of known habitats of filterable bacteria and provides data on two new or novel species.

Fe3O4/Graphene Oxide/Chitosan Nanocomposite: A Smart Nanosorbent for Lead(II) Ion Removal from Contaminated Water.

A new graphene oxide (GO) nanocomposite that contains chitosan, a biological polymer, combined with a magnetic nanoparticle inorganic material (Fe3O4) was successfully prepared and applied for the adsorption of Pb(II) from aqueous solutions. The structural and morphological properties of the GO/Fe3O4/CS (GFC) nanocomposites were characterized by X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. Influent factors for Pb(II) adsorption, including the contacting time, pH of the working medium, working temperature, and adsorbent dosage on the adsorption efficiency, have been optimized. Under optimized conditions, the adsorption isotherm results indicated that the Langmuir model provided a better description for the adsorption of Pb(II) onto the GFC nanosorbent than the Freundlich model. The maximum adsorption capacity (qmax) was 63.45 mg g-1. The pseudo-second-order kinetic model (R2 = 0.999) was fitted with the experimental results, implying that the adsorption of Pb(II) onto GFC is a chemical process. The thermodynamic studies demonstrated the exothermic nature of the adsorption process. Another advantage of the GFC nanosorbent for Pb(II) removal is its capability to be easily recovered under the use of an external magnet and subsequently regenerated. Our work demonstrated that the removal efficiency was stable after several regeneration cycles (i.e., approximately 12% reduction after four successive adsorption-desorption cycles), implying that the GFC nanosorbent exhibits satisfactory regeneration performance. Therefore, with high removal efficiency, high adsorption capacity, and stable reusability, the GFC nanocomposite is a remarkable application potential adsorbent for the in situ treatment of Pb(II) ion-containing aqueous solutions.

Stakeholders' preferences for the design and delivery of virtual care services: A systematic review of discrete choice experiments.

This systematic review aimed to synthesise evidence from discrete choice experiments (DCEs) eliciting preferences for virtual models of care, as well as to assess the quality of those DCEs and compare the relative preferences for different stakeholder groups. Articles were included if published between January 2010 and December 2022. Data were synthesised narratively, and attributes were assessed for frequency, significance, and relative importance using a semi-quantitative approach. Overall, 21 studies were included encompassing a wide range of virtual care modalities, with the most common setting being virtual consultations for outpatient management of chronic conditions. A total of 135 attributes were identified and thematically classified into six categories: service delivery, service quality, technical aspects, monetary aspects, health provider characteristics and health consumer characteristics. Attributes related to service delivery were most frequently reported but less highly ranked. Service costs were consistently significant across all studies where they appeared, indicating their importance to the respondents. All studies examining health providers' preferences reported either system performance or professional endorsement attributes to be the most important. Substantial heterogeneity in attribute selection and preference outcomes were observed across studies reporting on health consumers' preferences, suggesting that the consideration of local context is important in the design and delivery of person-centred virtual care services. In general, the experimental design and analysis methods of included studies were clearly reported and justified. An improvement was observed in the quality of DCE design and analysis in recent years, particularly in the attribute development process. Given the continued growth in the use of DCEs within healthcare settings, further research is needed to develop a standardised approach for quantitatively synthesising DCE findings. There is also a need for further research on preferences for virtual care in post-pandemic contexts, where emerging evidence suggests that preferences may differ to those observed in pre-pandemic times.

Regular Physician Access and Obesity Status Among Underserved Asian and Pacific Islander American Immigrants in Los Angeles.

According to prior research, Asian and Pacific Islander American (APIA) immigrants often refrain from seeking health care unless necessitated by medical conditions. Utilizing data from health screenings conducted in APIA immigrant enclaves in Los Angeles, we hypothesize that poorer obesity status would predict higher rates of regular physician access. Analyses involved objectively measured percent body fat (%BF) and survey responses collected between 2011 and 2019. We assessed the association between obesity status and regular physician access, adjusting for insurance status, demographic, and socioeconomic factors. The study population (n = 4102) primarily consisted low-income, low English proficiency APIAs. Participants with a regular physician were significantly more likely to be obese compared to participants without (adjusted odds ratio [aOR] = 1.28). This association may suggest that care was sought reactively rather than proactively within this community. Interventions with emphasis on cultural competency and language services may encourage preventative care utilization among this understudied community.

Intranasal administration of DSM 32444 Bacillus subtilis spores: safety and tolerability.

Introduction. Administered nasally, spores of the Gram-positive bacterium Bacillus subtilis have been shown to be able to induce innate immunity sufficient to confer protection to influenza and respiratory syncytial virus.Hypothesis. Although members of the aerobiome, intranasal delivery of high numbers of live spores carries potential safety issues.Aim. To address the potential safety risk of using live spores, we assessed the safety of spores that had been completely inactivated using heat sterilization.Methodology. Using autoclaved, and therefore killed, spores of a generally recognized as safe-notified B. subtilis strain (DSM 32444), safety was assessed in vitro (biotype, genome and cell based cytoxicity) and in vivo, using intranasal administration in rodent models and lastly in human volunteers.Results. Using a 15-day, repeat-dose, regimen in a rodent model, no indication of toxicity was observed. In a registered human study (NCT05984004), a formulated preparation of inactivated DSM 32444 spores referred to as SPEROVID was developed, and tolerance in human volunteers was assessed following 7 days of nasal dosing (2-4 times/day).Conclusion. Our study demonstrated that in humans an intranasal dose of up to 3×108 killed spores was safe and well tolerated.

The effectiveness of telemedicine in the management of type 2 diabetes: A systematic review.

Background: Type 2 diabetes, a lifestyle-related disease demanding daily self-management, is a significant health concern. In this context, the use of telemedicine as a management tool is a relatively new and promising approach. This study aims to contribute to the growing body of knowledge by identifying the effectiveness of telemedicine in managing type 2 diabetes through a systematic review approach. Methods: Four databases were searched including PubMed, Virtual Health Library, Global Health Library, and Google Scholar on 27 July 2022. Additionally, a manual search was performed to identify any relevant articles that may have been missed. The quality of the included articles was rigorously assessed using the Study Quality Assessment Tools of the National Institute of Health. Results: We analyzed data from 134 articles. All 134 studies were published between 2002 and 2022, including 103 controlled intervention trials, 13 cohort studies, 7 before-after (pre-post) studies with no control group, 1 initial trial, 1 case study, 1 pilot study, and 8 two-arm studies that did not report the study design. Accordingly, most studies show positive changes in glycemic index in every group using telemedicine. Overall, although the BMI and weight indices in the studies improved at the end of the course, the improvement values were considered insignificant. Conclusion: Telemedicine may be a valuable solution for blood sugar management in patients with type 2 diabetes. However, the effectiveness of telemedicine in improving BMI and quality of life is unclear.

Lack of SPNS1 results in accumulation of lysolipids and lysosomal storage disease in mouse models.

Accumulation of sphingolipids, especially sphingosines, in the lysosomes is a key driver of several lysosomal storage diseases. The transport mechanism for sphingolipids from the lysosome remains unclear. Here, we identified SPNS1, which shares the highest homology to SPNS2, a sphingosine-1-phosphate (S1P) transporter, functions as a transporter for lysolipids from the lysosome. We generated Spns1-KO cells and mice and employed lipidomic and metabolomic approaches to reveal SPNS1 ligand identity. Global KO of Spns1 caused embryonic lethality between E12.5 and E13.5 and an accumulation of sphingosine, lysophosphatidylcholines (LPC), and lysophosphatidylethanolamines (LPE) in the fetal livers. Similarly, metabolomic analysis of livers from postnatal Spns1-KO mice presented an accumulation of sphingosines and lysoglycerophospholipids including LPC and LPE. Subsequently, biochemical assays showed that SPNS1 is required for LPC and sphingosine release from lysosomes. The accumulation of these lysolipids in the lysosomes of Spns1-KO mice affected liver functions and altered the PI3K/AKT signaling pathway. Furthermore, we identified 3 human siblings with a homozygous variant in the SPNS1 gene. These patients suffer from developmental delay, neurological impairment, intellectual disability, and cerebellar hypoplasia. These results reveal a critical role of SPNS1 as a promiscuous lysolipid transporter in the lysosomes and link its physiological functions with lysosomal storage diseases.

Antimalarial activities of benzothiazole analogs: A systematic review.

BACKGROUND: Benzothiazole derivatives have been reported to possess a wide range of biological activities, including antimalarial activity. This systematic review aims to summarize and evaluate the antimalarial activities of benzothiazole analogs. METHODS: We conducted an electronic search using nine databases in October 2017 and subsequently updated in September 2022. We included all original in vitro and in vivo studies that documented the antimalarial activities of compounds containing benzothiazole analogs with no restriction. The risk of bias of each included study was assessed by ToxRTool. RESULTS: Twenty-eight articles were included in our study, which are in vitro, in vivo, or both. Of these, 232 substances were identified to have potent antiplasmodial activity against various strains of the malaria parasite. Benzothiazole analogs show different antimalarial mechanisms, including inhibition of Plasmodium falciparum enzymes in in vitro studies and inhibition of blood parasites in in vivo studies. CONCLUSIONS: Benzothiazole derivatives are promising substances for treating malaria. The structure-activity relationship studies suggest that the substitution pattern of the benzothiazole scaffold plays a crucial role in determining the antimalarial activity of the analog.

Implementation of Telepharmacy to Provide Medication Consultation Service for Patients: A Case Study From Thu Duc City Hospital, Ho Chi Minh City.

Telepharmacy is receiving significant attention as an innovative approach. The objective of this study is to assess the needs and evaluate the impact of telepharmacy applications in drug consultations at Thu Duc City Hospital. We used a cross-sectional research design and conducted a survey with the participation of leaders of the Faculty of Pharmacy, clinical pharmacists, dispensing pharmacists, and patients or their caregivers who receive medication at the Pharmacy of Thu Duc Hospital. We deployed a telepharmacy application for consulting on drug use and surveyed the satisfaction of patients/family members with the telepharmacy model. 60.3% of survey subjects expressed a desire to receive drug use consultations through telepharmacy if the hospital were to offer this service. One hundred percent of the pharmacists at the pharmacy and the hospital's leadership believe that telepharmacy can address patient consultation needs and improve the current physical facilities in the dispensing area. Over 90% of telepharmacy users reported being satisfied or very satisfied with the service. Telepharmacy has garnered the attention of patients, their caregivers, and the medical staff at the Outpatient Pharmacy of Thu Duc Hospital. The majority of users are satisfied with the drug use consultation service provided by telepharmacy. By expanding the good results of Thu Duc Hospital to other hospitals, more patients across Vietnam can benefit from this innovative approach.

Preferences in the Design and Delivery of Neurodevelopmental Follow-Up Care for Children: A Systematic Review of Discrete Choice Experiments.

Neurodevelopmental disorders are a significant cause of morbidity. Early detection of neurodevelopmental delay is essential for timely diagnosis and intervention, and it is therefore important to understand the preferences of parents and clinicians for engaging with neurodevelopmental surveillance and follow-up care. Discrete choice experiment (DCE) may be an appropriate method for quantifying these preferences. This review systematically examined how DCEs have been designed and delivered in studies examining neurodevelopmental care of children and identified the preferred attributes that have been reported. PubMed, Embase, CINAHL, and Scopus databases were systematically searched. Studies were included if they used DCE to elicit preferences for a neurodevelopmental follow-up program for children. Two independent reviewers conducted the title and abstract and full-text screening. Risk of bias was assessed using a DCE-specific checklist. Findings were presented using a narrative synthesis. A total of 6618 records were identified and 16 papers were included. Orthogonal (n=5) and efficient (n=5) experimental designs were common. There was inconsistent reporting of design-related features. Analysis was primarily completed using mixed logit (n=6) or multinomial logit (n=3) models. Several key attributes for neurodevelopmental follow-up care were identified including social, behavioral and emotional support, therapy, waiting time, and out-of-pocket costs. DCE has been successfully used as a preference elicitation method for neurodevelopmental-related care. There is scope for improvement in the design and analysis of DCE in this field. Nonetheless, attributes identified in these studies are likely to be important considerations in the design and implementation of programs for neurodevelopmental care.
