ABSTRACT

BACKGROUND: Intensive support teams (ISTs) are recommended for individuals with intellectual disabilities who display behaviours that challenge. However, there is currently little evidence about the clinical and cost-effectiveness of IST models operating in England.

AIMS: To investigate the clinical and cost-effectiveness of IST models.

METHOD: We carried out a cohort study to evaluate the clinical and cost-effectiveness of two previously identified IST models (independent and enhanced) in England. Adult participants (n = 226) from 21 ISTs (ten independent and 11 enhanced) were enrolled. The primary outcome was change in challenging behaviour between baseline and 9 months as measured by the Aberrant Behaviour Checklist-Community version 2.

RESULTS: We found no statistically significant differences between models for the primary outcome (adjusted β = 4.27; 95% CI -6.34 to 14.87; P = 0.430) or any secondary outcomes. Quality-adjusted life-years (0.0158; 95% CI: -0.0088 to 0.0508) and costs (£3409.95; 95% CI -£9957.92 to £4039.89) of the two models were comparable.

CONCLUSIONS: The study provides evidence that both models were associated with clinical improvement for similar costs at follow-up. We recommend that the choice of service model should rest with local services. Further research should investigate the critical components of IST care to inform the development of fidelity criteria, and policy makers should consider whether roll out of such teams should be mandated.

ABSTRACT

Healive® was the only Chinese WHO-prequalified inactivated vaccine for the hepatitis A virus, which has been widely used in national immunization programs in China. Long-term follow-up studies are needed to estimate the persistence of vaccine-induced antibody levels and the necessity for booster vaccines. During the trial, geometric mean concentrations (GMCs) and seroconversion rates (SRs) of anti-HAV antibodies were compared based on two different inactivated hepatitis A vaccines, Healive® and Havrix®. Four hundred children were randomly assigned to receive two doses of Healive® or Havrix® at 0 and 6 months. The current study assessed antibody persistence for both vaccines 15 years post-immunization. A mixed linear model was used to predict long-term antibody persistence. The GMCs were significantly higher for Healive® compared to Havrix® at 1, 6, 7, 66, 138 months (P < .001) and 186 months (P = .004 < .05) post-vaccination. Healive® and Havrix® reached a GMC of 164.8 mIU/ml and 105.7 mIU/ml post-15 years of vaccination, respectively. The seroconversion rates of both vaccines showed no statistically significant differences (97.9% for Healive® and 94.7% for Havrix®, P = .20). The prediction showed that Healive® would provide protection for a minimum of 30 years following immunization, with a lower limit of the 95% confidence intervals for GMCs greater than 20mIU/mL. Compared to Havrix®, the vaccine Healive® showed a stronger protective effect and better persistence among children at 15 years post-full immunization. Prediction indicated at least 30 years of antibody persistence for Healive® and at least 25 years for Havrix®.

ABSTRACT

The Mediterranean diet is often proposed as a sustainable diet model. This study aimed to evaluate the associations between adherence to the Mediterranean diet and sustainability domains in a cohort of French adults, using multiple criteria including nutritional quality, environmental pressures, monetary cost, and dietary pesticide exposure. Food intakes of 29,210 NutriNet-Santé volunteers were assessed in 2014 using a semi-quantitative food frequency questionnaire. Adherence to the Mediterranean diet was evaluated using the validated literature-based adherence score (MEDI-LITE). The associations between the MEDI-LITE and various sustainability indicators were examined using analysis of covariance models, adjusted for sex, age and energy intake. Higher adherence to the MEDI-LITE was associated with higher nutritional quality scores, better overall nutrient profile as well as reduced environmental impact (land occupation: Q5 vs. Q1: -35%, greenhouse gas emissions: -15%, and cumulative energy demand: -17%). In turn, monetary cost increased with increasing adherence to the Mediterranean diet (Q5 vs. Q1: +15%) while higher adherents to the Mediterranean diet had overall higher pesticide exposure due to their high plant-based food consumption. In this large cohort of French adults, greater adherence to the Mediterranean diet was associated with nutritional and environmental benefits, but also with higher monetary cost and greater exposure to pesticides, illustrating the necessity to develop large-scale strategies for healthy, safe (pesticide- and contaminant-free), and environmentally sustainable diets for all.

ABSTRACT

AIM: The premixed bioceramic sealer iRoot SP that is widely used clinically has been reported to kill bacterial biofilms and promote osteogenic differentiation of human stem cells from the apical papilla (hSCAPs). Although miR-141-3p has been substantiated to be involved in the osteogenic process, the underlying mechanisms remain unclear. The aim of this study was to investigate the role of miR-141-3p in osteogenic differentiation and underlying mechanisms of iRoot SP-treated hSCAPs.

METHODOLOGY: hSCAPs were extracted from tissue blocks with enzyme digestion and identified with using by immunofluorescence, flow cytometry and alizarin red staining. The mRNA expression level of miR-141-3p in hSCPAs after culture with iRoot SP was examined by quantitative real-time PCR (qRT-PCR) assay. SPAG9 was identified as a downstream target gene of miR-141-3p by dual-luciferase report assay. Alkaline phosphatase (ALP) staining and activity detection, alizarin red staining, calcium concentration assay, qRT-PCR and western blot were used to estimate osteogenic differentiation ability and involved protein expression levels of the osteogenic makers and signaling pathway-related factors in iRoot SP-treated hSCAPs. Data were analyzed by one-way ANOVA and post hoc Tukey’s test to determine any statistical differences between the experimental groups and the control group. P < 0.05 was considered statistically significant.

RESULTS: Expression of miR-141-3p was reduced in iRoot SP-treated hSCAPs with the increased exposure time up to 7 days and the western blot and qRT-PCR results revealed that the osteogenic markers osteocalcin (OCN), osterix (OSX), runt-related transcription factor 2 (RUNX2) and dentin sialophosphoprotein (DSPP) were inversely correlated with miR-141-3p. The negative regulatory relationship between miR-141-3p and SPAG9/ mitogen-activated protein kinases (MAPK) signalling axis was validated in this in vitro experiments.

CONCLUSION: The bioceramic sealer iRoot SP promoted osteogenic differentiation of hSCAPs by inhibiting miR-141-3p following down-regulated SPAG9 expression, and activated MAPK pathway. These findings proposed a novel therapeutic impact of bioceramic sealer iRoot SP inducing bone regeneration in refractory periapical periodontitis.

ABSTRACT

OBJECTIVE: Cutaneous relief analysis is crucial in the development of new skincare products, as well as in the evaluation of dermatological treatments. The analysis can be performed by qualitative or quantitative methods. We propose a new algorithm to detect wrinkles and quantify skin roughness by image processing from a dermatoscope.

METHODS: A clinical study was carried out with 33 research participants, and images were collected with the dermatoscope and PRIMOS equipment for wrinkle evaluation at two different times: Day 0 (D0) and 45 days (D45) after the use of a dermocosmetic product. Later, a new algorithm was developed to detect wrinkles in the acquired images by applying filters and image transformations that generate a segmented image highlighting the wrinkles. A roughness calculation method is proposed from the pixels belonging to wrinkles.

RESULTS: Correlation between the values obtained by the PRIMOS equipment and the proposed system was verified. No correlation was found for data obtained at D0; however, there was correlation at time D45 by Spearman’s similarity coefficient. By comparing roughness between times D0 and D45, the treatment was statistically significant for both PRIMOS and the proposed methodology data.

CONCLUSION: The wrinkle detection algorithm, in addition to the roughness calculation, demonstrated a sensitivity comparable to the PRIMOS system in evaluating the effectiveness of the dermocosmetic treatment.

SIGNIFICANCE: Considering the simplicity of the dermatoscope design compared to other established devices such as PRIMOS, the proposed system is promising as an alternative for dermatological evaluations.

ABSTRACT

BACKGROUND: The mechanism of intense pulsed light action on the skin is based on selective photothermolysis. The light delivered to the tissue is scattered and absorbed by chromophores that absorb a beam of radiation of a specific length. The skin reflectance changes depending on the physiological state of the tissue, as shown by the hyperspectral camera. The aim of the study was to assess the hyperspectral reflectance of acne skin before and after intense pulsed light (IPL) therapy and to compare it with the reflectance of healthy skin.

MATERIALS AND METHODS: The study involved 27 volunteers with diagnosed moderate acne. The control group consisted of 20 people without acne lesions. All acne volunteers underwent a series of four treatments using IPL at weekly intervals. The volunteers with acne lesions were photographed before the series of treatments and a week after the 4th treatment.

RESULTS: Acne skin shows lower reflectance than healthy skin. Acne skin after IPL therapy is characterized by a higher reflectance compared to acne skin before the therapy and resembles the reflectance of the skin of the control group. A statistically significant difference was found between the acne skin before the treatments and the skin of the control group.

CONCLUSIONS: The effect of IPL therapy on acne skin is the increase of its reflectance by reducing the number of chromophores, which brings it closer to the reflectance value of healthy skin. Hyperspectral imaging allows for: the evaluation of the treated skin at each stage, a precise selection of the light wavelength depending on the problem, and therefore, for optimizing the number of irradiations and increasing the safety of the therapy.

ABSTRACT

BACKGROUND: The application of polyhydroxy acids and alpha-hydroxy acids to the skin is often used in cosmetology. To enhance the effect of gluconolactone chemical peeling, a combined method including water-oxygen oxybrasion or microneedle mesotherapy can be used.

OBJECTIVES: To evaluate skin parameters such as hydration, sebum, pH and TEWL after application of a 10% gluconolactone chemical peel in combination with oxybrasion and microneedling.

MATERIALS AND METHODS: Twenty-one Caucasian women participated in the study. A series of three split face treatments was carried out at 1-week intervals. Oxybrasion was performed on the right side of the face and micro-needle mesotherapy on the left side. A 10% gluconolactone solution was applied to the entire face. Before the first and third treatments and 2 weeks after the last treatment, skin parameters were evaluated. Photographic documentation was also made before and after the treatment series.

RESULTS AND CONCLUSION: Evaluation of skin parameters using Courage & Khazaka 580 Multi Probe Adapter probes (Courage + Khazaka electronic GmbH, Cologne, Germany) showed an increase in hydration and a decrease in sebum, pH and TEWL for both treatments. There were no statistically significant differences between the treatments. Combining chemical peeling of gluconolactone with oxybrasion and microneedle mesotherapy is a good method to seal the hydrolipid barrier and increase skin hydration.

ABSTRACT

BACKGROUND: Piebaldism is a rare, autosomal dominant, and congenital pigmentary disorder characterized by stable depigmentation of the skin and white forelock. Mutations in KIT or SLUG genes result in piebaldism. Most individuals with piebaldism have a family history of the disorder.

METHODS: In this paper, we report a case of piebaldism with café-au-lait macules resulting from a novel mutation of KIT gene c.1982C > T (p.Thr661Ile) in a three-generation Chinese family. The whole-exome sequencing, mitochondrial gene 3000X, and bioinformatics tools were used to identify the mutation in this new-found pedigree. In addition, we searched the databases of “Punmed, Chinese National Knowledge Infrastructure, CMJD, WANFANG MED ONLINE”, reviewed 88 cases of piebaldism caused by KIT gene mutation, and summarized the relationship between clinical phenotype and genotype of piebaldism through logistic regression and other statistical methods.

RESULTS: The proband and her affected mother carried a heterozygous c.1982C > T missense mutation (p.Thr661Ile) on KIT gene. Bioinformatics analysis hinted that it had potential pathogenicity. The data showed that piebaldism patients with cafè-au-lait macules had KIT mutations almost located in the intracellular tyrosine kinase domain and were mostly related to the severe clinical phenotype of piebaldism.

CONCLUSION: The new heterozygous c.1982C > T missense mutation on KIT caused piebaldism with café-au-lait macules in this Chinese family. This study provides a new reference index for clinicians to judge the severity of clinical phenotypes of piebaldism, broadens the understanding of the correlation between clinical phenotypes and genotypes of piebaldism, and provides reference of genetic counseling and prenatal diagnosis for affected families.

ABSTRACT

BACKGROUND: Oral supplementation with some amino acids (like methionine, taurine, and cysteine) could be useful in subjects with hair loss conditions such as androgenic alopecia (AGA or FAGA) or telogen effluvium (TE). Hydrolysed collagen (HC) oral supplementation has demonstrated to have beneficial effects on nail and skin health and could improve hair growth. A food supplement in tablet formulation containing hydrolysed fish-origin collagen (300 mg/dose), taurine, cysteine, methionine, iron, and selenium has been recently available. To date no controlled data are available regarding the clinical efficacy of this product as adjuvant to hair loss specific treatments in these clinical conditions.

STUDY AIMS: To evaluate and compare the efficacy and tolerability of an oral supplementation based on HC and amino acids in subjects with hair loss due to AGA/FAGA or chronic TE in combination with drug treatments in comparison with drug treatments alone.

METHODS AND SUBJECTS: In a prospective, 12-week, randomized, assessor-blinded controlled trial 83 subjects (mean age 41 ± 16 years; 26 men and 57 women) were enrolled in the study. Fifty-nine subjects suffered from AGA/FAGA (Hamilton I-VA, Ludwig I-1, II-2) and 24 from chronic TE. Subjects were randomized to oral supplementation (1 tablet day) in combination with the specify drug treatment decided by the investigator according to the type of hair loss (AGA/FAGA or TE) (Group A; N = 48) or to specific drugs treatment only (Group B; N = 35). The main outcome of the trial was the clinical efficacy evaluation using a 7-point global assessment score (GAS) (from +3: Much Improved to -3 Much worsened; with score 0 representing no modification). The GAS score was evaluated using standardized photographs by an investigator unaware of the treatment groups at week 6 and at week 12. A secondary outcome was the evaluation of acceptability of the treatment regimen using a 10-point evaluation score.

RESULTS: Seventy-six participants (91.6%) completed the 12-week study period. The GAS score at week 6 was 0.5 ± 0.2 in group A and 0.0 ± 0.1 in Group B (p < 0.05; Mann-Whitney). At week 12 the GAS score in Group A was statistically significant higher in comparison with Group B (1.67 ± 0.16 and 0.66 ± 0.20, p < 0.001; Mann-Whitney test). A higher percentage of Group A subjects achieved a GAS score of ≥2 in comparison with group B (50% vs. 23%). The oral supplement was generally well tolerated.

CONCLUSION: An oral supplement containing hydrolysed fish-origin collagen, taurine, cysteine, methionine, iron, and selenium has demonstrated to improve the clinical efficacy of specific anti-hair loss treatments in subjects with AGA/FAGA or chronic TE.

ABSTRACT

Objective: To explore the key points for preventing and reducing severe pre-eclampsia (SPE) and its severe complications in the tertiary medical referral system of a second-tier city by analyzing the clinical characteristics of SPE. Methods: The clinical data of 341 patients with SPE who terminated pregnancy in Women and Children’s Hospital, School of Medicine, Xiamen University, from January 1, 2020 to December 31, 2022 were retrospectively analyzed, and the pre-eclampsia (PE) risk factors, clinical characteristics and severe complications of SPE between the patients referred from primary hospitals (referral group) and the patients received regular prenatal care in the tertiary referral center (central group) were compared, as well as the influence of the referral timing on the maternal and perinatal outcomes. Results: Among the 341 cases of SPE, 92 cases were in the referral group and 249 cases were in the central group. (1) Analysis of PE risk factors: there was no statistical difference in the proportion of risk factors of PE between these two groups [75.0% (69/92) vs 71.9% (179/249); χ²=0.328, P=0.567]. (2) Analysis of clinical features: the gestational ages at the PE early warning factors onset, at the PE first symptom onset and at SPE diagnosed, pregnancy terminated and onset of SPE severe complications in the referral group were significantly earlier than those in the central group (all P<0.05), the proportions of terminating pregnancy before 32 weeks of gestation, between 32 and 34 weeks of gestation, intensive care unit (ICU), neonatal ICU hospitalization and fetal growth restriction in single pregnancies were higher than those in the central group, while the live birth rate was lower than that in the central group (all P<0.05). (3) Analysis of SPE severe complications: the rates of SPE severe complications in the referral group was higher than that in the central group [28.3% (26/92) vs 13.7% (34/249); χ²=9.885, P=0.002]. Among them, the rates of placental abruption [7.6% (7/92) vs 2.8% (7/249); χ²=3.927, P=0.048] and still birth [6.5% (6/92) vs 0.4% (1/249); χ²=9.656, P=0.002] in the referral group were significantly higher than those in the central group. (4) Analysis of referral timings: the timings included referral after onset of SPE severe complications (9.8%, 9/92), referral after SPE diagnosed (63.0%, 58/92), referral after detection of SPE early warning signs (20.7%, 19/92) and referral after detection of PE risk factors (6.5%, 6/92). The gestational ages at SPE diagnosed and pregnancy terminated in group of referral after onset of SPE severe complications and group of referral after SPE diagnosed were significantly earlier than those in group of referral after detection of PE early warning signs and group of referral after detection of PE risk factors (P<0.05). The earlier the referral, the higher the live birth rates (P<0.05). Conclusions: The tertiary referral center of the second-tier city plays an important role in reducing the maternal and perinatal damage of PE. The timing of referral in primary medical institutions is the key point of reducing the occurrence of SPE severe complications and maternal, perinatal damage of PE. It is necessary for medical institutions of all levels in all regions to improve the ability of early identification and early intervention for PE, to enhance the awareness of SPE and its severe complications prevention and control. Primary medical institutions should especially pay attention to raise the consciousness of PE risk factors and early warning signs, and to improve the ability of PE risk factors and early warning signs screening.
