Authors: Li Shijie , Cui Heshuai , Ma Qianli , Liu Xing’e , Wang Youhong , Shang Lili , Zheng Yu
Published: October 2021

The sol–gel method was used to prepare rattan-based silicon carbide (R–SiC) composite ceramics under different pyrolysis parameters through adjustment of the temperature and retention time of the one-step pyrolysis process. The crystalline phases, microscopic morphology, element distribution and specific surface area of the silicon carbide (SiC) were characterized by X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR), X-ray fluorescence spectrometer (XRF), field-emission scanning electron microscope (FESEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), and N2 physisorption. The results showed that the R–SiC prepared at different pyrolysis parameters was able to retain the porous structure of pristine rattan stem. The R–SiC prepared at 1500 ℃ for 120 min possessed the lowest density (0.25 g/cm3), the largest specific surface area (43.38 m2/g) and the highest SiC yield (44.24%). The SiC whisker was the major SiC morphology on the cross section of the R–SiC. Furthermore, the pyrolysis parameters were optimized with the SiC preparation process reaction mechanism, and material transformation methods were also discussed. This one-step pyrolysis process simplified the preparation of biogenic SiC ceramics and thus provided a potential route for the value-added utilization of rattan.
Annotation depth confounds direct comparison of gene expression across species
Authors: Oziolor Elias , Arat Seda , Martin Matthew
Published: October 2021

Background

Comparisons of the molecular framework among organisms can be done on both structural and functional levels. One of the most common top-down approaches for functional comparisons is RNA sequencing. This estimation of organismal transcriptional responses is of interest for understanding evolution of molecular activity, which is used for answering a diversity of questions ranging from basic biology to pre-clinical species selection and translation. However, direct comparison between species is often hindered by evolutionary divergence in structure of molecular framework, as well as large difference in the depth of our understanding of the genetic background between humans and other species. Here, we focus on the latter. We attempt to understand how differences in transcriptome annotation affect direct gene abundance comparisons between species.

Results

We examine and suggest some straightforward approaches for direct comparison given the current available tools and using a sample dataset from human, cynomolgus monkey, dog, rat and mouse with a common quantitation and normalization approach. In addition, we examine how variation in genome annotation depth and quality across species may affect these direct comparisons.

Conclusions

Our findings suggest that further efforts for better genome annotation or computational normalization tools may be of strong interest.

Authors: Zhuang Defeng , Ma Ce , Xue Li , Li Zhen , Wang Cheng , Lei Jiajun , Yuan Xingfu
Published: October 2021

Background

Rose is one of most popular ornamental plants worldwide and is of high economic value and great cultural importance. However, cold damage restricts its planting application in cold areas. To elucidate the metabolic response of rose under low temperature stress, we conducted transcriptome and de novo analysis of Rosa xanthina f. spontanea.

Results

A total of 124,106 unigenes from 9 libraries were generated by de novo assembly, with N50 length was 1470 bp, under 4 °C and − 20 °C stress (23 °C was used as a control). Functional annotation and prediction analyses identified 55,084 unigenes, and 67.72% of these unigenes had significant similarity (BLAST, E ≤ 10− 5) to those in the public databases. A total of 3031 genes were upregulated and 3891 were downregulated at 4 °C compared with 23 °C, and 867 genes were upregulated and 1763 were downregulated at − 20 °C compared with 23 °C. A total of 468 common DEGs were detected under cold stress, and the matched DEGs were involved in three functional categories: biological process (58.45%), cellular component (11.27%) and molecular function (30.28%). Based on KEGG functional annotations, four pathways were significantly enriched: metabolic pathway, response to plant pathogen interaction (32 genes); starch and sucrose metabolism (21 genes); circadian rhythm plant (8 genes); and photosynthesis antenna proteins (7 genes).

Conclusions

Our study is the first to report the response to cold stress at the transcriptome level in R. xanthina f. spontanea. The results can help to elucidate the molecular mechanism of cold resistance in rose and provide new insights and candidate genes for genetically enhancing cold stress tolerance.
Genome-wide survey of Gγ subunit gene family in eight Rosaceae and expression analysis of PbrGGs in pear (Pyrus bretschneideri)
Authors: Chen Guodong , Li Yang , Qiao Xin , Duan Weike , Jin Cong , Cheng Rui , Wang Jizhong
Published: October 2021

Background

Heterotrimeric G-proteins, composed of Gα, Gβ and Gγ subunits, are important signal transmitters, mediating the cellular response to multiple stimuli in animals and plants. The Gγ subunit is an essential component of the G-protein, providing appropriate functional specificity to the heterotrimer complex and has been well studied in many species. However, the evolutionary history, expression pattern and functional characteristics of Gγ subunits has not been explored in the Rosaceae, representing many important fruit crops.

Results

In this study, 35 Gγ subunit genes were identified from the eight species belonging to the Rosaceae family. Based on the structural gene characteristics, conserved protein motifs and phylogenetic analysis of the Gγ subunit genes, the genes were classified into three clades. Purifying selection was shown to play an important role in the evolution of Gγ subunit genes, while a recent whole-genome duplication event was the principal force determining the expansion of the Gγ subunit gene family in the subfamily Maloideae. Gγ subunit genes exhibited diverse spatiotemporal expression patterns in Chinese white pear, including fruit, root, ovary and bud, and under abiotic stress conditions, the relative expression of Gγ subunit genes were up-regulated or down-regulated. In addition, seven of the Gγ subunit proteins in pear were located on the plasma membrane, in the cytoplasm or nucleus.

Conclusion

Overall, this study of the Gγ subunit gene family in eight Rosaceae species provided useful information to better understand the evolution and expression of these genes and facilitated further exploration of their functions in these important crop plants.
Exploring antibiotic prescribing in public and private primary care settings in Singapore: a qualitative analysis informing theory and evidence-based planning for value-driven intervention design
Authors: Guo Huiling , Hildon Zoe Jane-Lara , Loh Victor Weng Keong , Sundram Meena , Ibrahim Muhamad Alif Bin , Tang Wern Ee , Chow Angela
Published: October 2021

Background

Singapore’s healthcare system presents an ideal context to learn from diverse public and private operational models and funding systems.

Aim

To explore processes underpinning decision-making for antibiotic prescribing, by considering doctors’ experiences in different primary care settings.

Methods

Thirty semi-structured interviews were conducted with 17 doctors working in publicly funded primary care clinics (polyclinics) and 13 general practitioners (GP) working in private practices (solo, small and large). Data were analysed using applied thematic analysis following realist principles, synthesised into a theoretical model, informing solutions to appropriate antibiotic prescribing.

Results

Given Singapore’s lack of national guidelines for antibiotic prescribing in primary care, practices are currently non-standardised. Themes contributing to optimal prescribing related first and foremost to personal valuing of reduction in antimicrobial resistance (AMR) which was enabled further by organisational culture creating and sustaining such values, and if patients were convinced of these too. Building trusting patient-doctor relationships, supported by reasonable patient loads among other factors were consistently observed to allow shared decision-making enabling optimal prescribing. Transparency and applying data to inform practice was a minority theme, nevertheless underpinning all levels of optimal care delivery. These themes are synthesised into the VALUE model proposed for guiding interventions to improve antibiotic prescribing practices.

These should aim to reinforce intrapersonal Values consistent with prioritising AMR reduction, and Aligning organisational culture to these by leveraging standardised guidelines and interpersonal intervention tools. Such interventions should account for the wider systemic constraints experienced in publicly funded high patient turnover institutions, or private clinics with transactional models of care. Thus, ultimately a focus on Liaison between patient and doctor is crucial. For instance, building in adequate consultation time and props as discussion aids, or quick turnover communication tools in time-constrained settings. Message consistency will ultimately improve trust, helping to enable shared decision-making. Lastly, Use of monitoring data to track and Evaluate antibiotic prescribing using meaningful indicators, that account for the role of shared decision-making can also be leveraged for change.

Conclusions

These VALUE dimensions are recommended as potentially transferable to diverse contexts, and the model as implementation tool to be tested empirically and updated accordingly.
Cavernous hemangioma of the mesorectum involving the rectum: a rare case report
Authors: Zhang Yan , Wu Bing
Published: October 2021

Background

Gastrointestinal hemangiomas are very rare and are even rarer in the mesorectum. It is not clear whether mesorectal hemangiomas originate in the bowel wall or in the mesorectum. For clinicians, to correctly identify the imaging features of mesorectal hemangiomas is important.

Case presentation

We herein describe a case of a 31-year-old male that presented with hematochezia and sensation of rectal tenesmus. Both the rectal MRI and contrast-enhanced CT scan of the whole abdomen indicated rectal wall thickening, marked dilatation, and tortuous vessels around the rectum. In addition, a contrast-enhanced portal venous phase CT scan showed the dilation of portal vein, splenic vein and inferior mesenteric vein. The dilated inferior mesenteric vein extending down to the mesorectum, and became marked dilatation and tortuous vessels around the rectum. The patient underwent laparoscopic surgical resection of the mesorectal lesion and the involved portions of the rectum. The surgical samples underwent pathological analysis, and a diagnosis of cavernous hemangioma was confirmed. Seven days after surgery, the patient was discharged without postoperative complications.

Conclusions

This case highlights the imaging features of mesorectal hemangiomas. In addition, in this current case, the mesorectal hemangioma more likely originated in the mesorectum.
Neonatal oral myiasis caused by the larvae of Sarcophaga ruficornis (Diptera: Sarcophagidae): a case report
Authors: Zhou Minyu , Cao Ke , Huang Hui , Luo Xiaojuan , Wang Ying , Ma Weike , Lv Zhiyue
Published: October 2021

Background

Myiasis is caused by dipterous larvae, and rarely affects the mouth. Diagnosis by traditional means is easy to be confused with other similar species. Here, we report a case of oral myiasis, in a 5-month-old infant who was diagnosed by morphological examination and molecular biological methods.

Case presentation

A 5-month old infant with acute myeloid leukemia was admitted due to recurrent skin masses for more than 4 months. The infant had lip swelling, which prevented him from closing the mouth and membranes were present in his mouth and there were also oral ulcers and erosions. Ten maggots were found in the mouth and one in the ear canal with pus flowing out and were confirmed as the third stage larvae of Sarcophaga ruficornis by morphological examination and a comparison of sequence of cytochrome oxidase subunit 1 (COX1) gene. After removal of the maggots and chemotherapy, the infant ’s condition was gradually improved.

Conclusions

To the best of our our knowledge, this is the first neonatal oral myiasis case reported in China and its diagnosis requires a high index of suspicion. Microscopy combined with specific DNA sequence analysis is an effective technological tool to provide rapid diagnoses of the larva specimen and cases of rare diseases, as illustrated in the current case.

Published: October 2021

Background

Melioidosis, the infection caused by Burkholderia pseudomallei, is associated with a high case fatality rate, due in part to difficulties in clinical recognition and diagnostic confirmation of the disease. Although head and neck involvement is common in children, specific disease manifestations differ between geographic regions. The aim of this study was to provide a detailed description of melioidosis of the head and neck among children in Sarawak, Malaysia, and determine if fine-needle aspiration of suspected head or neck lesions could improve melioidosis diagnosis.

Methods

We conducted a retrospective descriptive study of all children aged < 12 years with culture-confirmed melioidosis presenting with head and neck manifestations and admitted to Bintulu Hospital in Sarawak, Malaysia, from January 2011 until December 2020. Fine-needle aspiration of head and neck lesions suspected to be due to melioidosis with inoculation in blood culture bottles (FNA + BCB) was used from the beginning of 2016.

Results

Of 34 children with culture-confirmed melioidosis, 20 (59%) had an infection involving one or more sites in the head and neck. Of these, 17 (85%) were diagnosed in or after 2016. Cervical lymph nodes were the most common organ or site affected, involved in 19 (95%) children. Clinical presentations of B. pseudomallei lymph node infections were highly variable. Five (25%) children had salivary gland involvement. Lacrimal gland involvement (dacryocystitis) and skin or soft tissue infection (scalp abscess) were less frequent. B. pseudomallei was isolated from the head or neck using FNA + BCB in 15 (75%) children and by standard culture methods of direct plating of pus on agar following incision and drainage in only 2 (10%) children. B. pseudomallei was isolated from non-head or neck specimens or blood in 3 (15%) children.

Conclusions

Manifestations of pediatric head and neck melioidosis in Sarawak, Malaysia, differ from those of other regions. Fine-needle aspiration, mainly of affected cervical lymph nodes, facilitates B. pseudomallei detection and enables confirmation of melioidosis infections.

Published: October 2021

Background

Multiple Sclerosis (MS) is a burdensome, chronic and autoimmune disease of the central nervous system. We aimed to report the incidence, prevalence, mortality, and Disability Adjusted Life Years (DALYs) of MS in Iran at a national level for different age and sex groups over a period of 28 years (1990–2017).

Methods

Data were extracted from the Global Burden of Disease study (GBD) from 1990 to 2017, published by the Institute for Health Metrics and Evaluation. The incidence of DALYs and prevalence of MS were estimated to report the burden of MS based on sex and age in Iran from 1990 to 2017.

Results

At the national level, the Age-Standardized Incidence Rate (ASIR), Age-Standardized Prevalence Rate (ASPR), Age-Standardized DALYs Rate (ASDR) and the Age-Standardized Mortality Rate (ASMR) in Iran in 2017 were 2.4 (95% Uncertainty Interval [UI]: 2.1 to 2.7), 69.5 (62.1 to 77.8), 29.1 (23.6 to 34.7), and 0.4 (0.3 to 0.4) per 100,000 population, respectively. During the period of 1990 to 2017, all measures increased, and were higher among females. The incidence rate began upward trend at the age of 20 and attained its highest level at the age of 25.

Conclusion

In Iran, all of the age-standardized MS rates have been increasing during the 28 years from 1990 to 2017. Our findings can help policy makers and health planners to design and communicate their plans and to have a better resource allocation, depending on the incidence and prevalence of the growing numbers of MS patients in Iran.
A study on the timing of uterine artery embolization followed by pregnancy excision for cesarean scar pregnancy: a prospective study in China
Authors: Yu Liping , Yang Bikang , Xu Qinyang , Teng Yincheng , Xue Zhuowei
Published: October 2021

Background

Cesarean scar pregnancy (CSP) remains a sporadic and special form of ectopic pregnancy in which the fertilized ovum is implanted on a previous cesarean scar within 12 weeks. This study aims to evaluate the optimal time interval between uterine artery embolization (UAE) and curettage modalities in order to provide the best clinical outcomes.

Methods

From January 2018 to December 2020, we recruited 61 patients with CSP. They were randomly divided into two groups depending on whether the time interval between UAE and dilatation and curettage (D&C) requires additional hospitalization: 31 patients received prophylactic UAE followed by D&C on the same day (0–12 h; group A) and 30 patients need hospitalization (12–72 h; group B). The clinical characteristics, diagnostic data, and outcomes of the two groups were compared and analyzed.

Results

A total of 59 (96.72%) cases had responded well to the first treatment. One patient in each arm undergone retreatment, but none of the 61 patients needed additional hysterectomy. There was no considerable relationship between the two groups with respect to the intraoperative hemorrhage during D&C, serum index (containing β-hCG, hemoglobin, CRP, and D-dimer) on the first day after D&C, side effects (containing fever and abdominal pain), renal, hepatic, and coagulation function, time of CSP residual mass disappearance, and hospitalization cost. The time of serum β-hCG resolution after surgery was 41.22 ± 14.97 days in group A and 66.67 ± 36.64 days in group B (P = 0.027), and group A treatment resulted in a shorten hospital stay as compared with group B (4.81 ± 2.74 days vs. 6.80 ± 2.14 days, P <  0.001). However, the average hourly serum β-hCG decrease rate within 24 h and the leukocytes on the first day after D&C in group B were superior than in group A (P <  0.050).

Conclusion

For patients with CSP, UAE followed by D&C on the same day (0–12 h) appears to have more advantages in hospitalization and recovery time, while the long time interval (12–72 h) may have a lower risk of inflammation and a more rapid decrease in serum β-hCG level within 24 h after D&C surgery. The treatment of CSP should be individualized based on the conditions of patients.
Association of body-shape phenotypes with imaging measures of body composition in the UK Biobank cohort: relevance to colon cancer risk
Authors: Christakoudi Sofia , Tsilidis Konstantinos K. , Evangelou Evangelos , Riboli Elio
Published: October 2021

Background

Body mass index (BMI), waist and hip circumference are strongly correlated and do not reflect body composition. A Body Shape Index (ABSI) and Hip Index (HI) define waist and hip size among individuals with the same weight and height and would thus reflect body density. We examined differences in body composition between body-shape phenotypes defined with ABSI and HI and used this information to propose explanations for associations between body-shape phenotypes and colon cancer risk.

Methods

We used data from the UK Biobank Resource for 15,520 men, 16,548 women with dual-emission X-ray absorptiometry (DXA) measurements; 3997 men, 4402 women with magnetic resonance imaging (MRI) measurements; 200,289 men, 230,326 women followed-up for colon cancer. We defined body-shape phenotypes as: large-ABSI-small-HI (“apple”), small-ABSI-large-HI (“pear”), small-ABSI-small-HI (“slim”), large-ABSI-large-HI (“wide”). We evaluated differences in body composition in linear models and associations with colon cancer risk in Cox proportional hazards models adjusted for confounders and explored heterogeneity by BMI.

Results

Among individuals with the same height and weight, visceral adipose tissue (VAT) was lowest for “pear” and highest for “apple”, while abdominal subcutaneous adipose tissue (ASAT) was lowest for “slim” and highest for “wide” phenotype. In the gynoid region, differences between “apple” and “pear” phenotypes were accounted for mainly by fat mass in women but by lean mass in men. In men, lean mass was inversely associated with waist size, while the pattern of gynoid fat resembled ASAT in women. Lean and fat mass were higher for higher BMI, but not hand grip strength. Compared to normal weight “pear”, the risk of colon cancer in men (1029 cases) was higher for “apple” phenotype for normal weight (hazard ratio HR = 1.77; 95% confidence interval: 1.16–2.69) and comparably for overweight and obese, higher for “wide” phenotype for overweight (HR = 1.60; 1.14–2.24) and comparably for obese, but higher for “slim” phenotype only for obese (HR = 1.98; 1.35–2.88). Associations with colon cancer risk in women (889 cases) were weaker.

Conclusions

ABSI-by-HI body-shape phenotypes provide information for body composition. Colon cancer risk in men appears related to ASAT quantity for “slim” and “wide” but to factors determining VAT accumulation for “apple” phenotype.
Pregnancy and Infant Development (PRIDE)—a preliminary observational study of maternal adversity and infant development
Authors: Bowers Katherine , Ding Lili , Yolton Kimberly , Ji Hong , Nidey Nichole , Meyer Jerrold , Ammerman Robert T. , Van Ginkel Judith , Folger Alonzo
Published: October 2021

Background

Children from socioeconomically disadvantaged families have a markedly elevated risk for impaired cognitive and social-emotional development. Children in poverty experience have a high risk for developmental delays. Poverty engenders disproportionate exposure to psychological adversity which may contribute to impaired offspring development; however the effect may be mitigated by social support and other aspects of resilience. Our objective was to determine the association between maternal stress, adversity and social support and early infant neurobehavior and child behavior at two and three years.

Methods

We conducted a longitudinal mother-infant cohort study nested within a regional home visiting program in Cincinnati, Ohio. Four home study visits were completed to collect measures of maternal stress, adversity and social support and infant and child behavior. A measure of infant neurobehavior (‘high-arousal’ infant) was derived from the NICU Network Neurobehavioral Scale (NNNS) at 1 month and externalizing and internalizing symptoms were measured by the Child Behavior Checklist (CBCL) at 24 and 36 months. Linear and logistic regression identified associations between maternal risk/protective factors and infant and child behavioral measures. We used stratification and multiplicative interaction terms to examine potential interactions.

Results

We enrolled n = 55 pregnant mothers and follow 53 mother–offspring dyads at 1 month, 40 dyads at 24 months and 27 dyads at 36 months. Maternal adversity and protective factors were not associated with neurobehavior at one month. However, maternal depression and measures of distress in pregnancy were significantly associated with internalizing and externalizing symptoms at 24 and 36 months.

Conclusions

This pilot study established the feasibility of conducting longitudinal research within a community intervention program. In addition, although there were no statistically significant associations between maternal psychosocial factors in pregnancy and infant neurobehavior, there were several associations at 24 months, primarily internalizing symptoms, which persisted through 36 months. Future work will replicate findings within a larger study as well as explore mediators and modifiers of these associations.

Published: October 2021

Background

Progress feedback provides therapists with progress notes on a regular basis through the continuous assessment of participants throughout their treatment (e.g., symptoms, therapeutic alliance). While for adults the evidence base has increased over the years, progress feedback in the therapy of children and adolescents has not been sufficiently investigated. This manuscript describes the trial protocol of the OPTIE study: a randomized trial that tests the efficacy of a progress feedback system in children and adolescents under conditions of routine care.

Methods

The study is based on a randomized parallel-group trial with two treatment groups (routine, feedback) at an outpatient unit of a university hospital. The target sample size is 439 families consisting of children and adolescents aged 6 to17 years old with internalizing and/or externalizing symptoms. Both the patients and the therapists are independently assigned to the treatment groups by stratified block randomization. In both treatment groups patients receive routine care behavioral therapy for a study-related 12 months; additionally, in the feedback group, a progress feedback system with three components is applied (monitoring, report, and supervision). For three informants (caregiver, child [≥ 11 years], therapist) surveys are conducted every 6 weeks (e.g., symptoms, goals, motivation). For both treatment groups, comparison data is collected at baseline and at six and 12 months after the beginning of the intervention (pre, inter, post), and includes five informants (blinded clinician, therapist, caregiver, child [≥ 11 years], teacher).

Discussion

The OPTIE study will contribute to the evidence base of progress feedback in children and adolescents and has the potential to uncover treatments’ effects in the small to medium range. Noteworthy features are the inclusion of children younger than 10 years old and the consideration of a blinded clinician rating.

Mediation role of alexithymia, sensory processing sensitivity and emotional-mental processes between childhood trauma and adult psychopathology: a self-report study
Authors: Karaca Dinç Pelin , Oktay Seda , Durak Batıgün Ayşegül
Published: October 2021

Background

There is overwhelming evidence for a strong association between childhood trauma and adult psychopathology. This study aimed to investigate the mediation roles of alexithymia, sensory processing sensitivity, and emotional-mental processes in the relationship between childhood traumas and adult psychopathology.

Methods

The sample consisted of 337 people (78.9% female, 21.1% male) aged between 20 and 64 years. Participants filled the scales online via a Google form. Reading Mind in the Eyes (EYES), Sensory Processing Sensitivity Scale (SPS), Toronto Alexithymia Scale (TAS-26), Childhood Trauma Questionnaire (CTQ), and the Brief Symptom Inventory (BSI) were used. PROCESS (Model 4) macro was used to examine the mediating role of sensory processing sensitivity, alexithymia, and the EYES test results in the relationship between childhood trauma and psychopathology.

Results

The results of mediation analysis demonstrated that sensory processing sensitivity and alexithymia mediated the relationship between childhood trauma and adult psychopathology. However, the EYES test (mentalization) did not mediate in this relationship.

Conclusion

This study shows that childhood traumas may relate to more psychological symptoms in individuals with high sensory processing sensitivity and alexithymia. Our study may contribute to the understanding of what may lead to a person’s vulnerability to experiencing psychological symptoms after childhood trauma. It may be crucial that future treatment and intervention programs should include sensory sensitivity and alexithymia. Sensory processing sensitivity and alexithymia can be examined in the treatment of psychological problems of individuals who have experienced childhood trauma.
Association between healthy eating index-2015 and various cognitive domains in US adults aged 60 years or older: the National Health and Nutrition Examination Survey (NHANES) 2011–2014
Authors: Fan Yameng , Zhang Yinyin , Li Jiaqiao , Liu Yamei , Chang Huan , Jiang Yude , Tuo Xingxia , Zhou Long , Yu Yan
Published: October 2021

Background

Diet, as a modifiable factor, plays an important role in cognitive function. However, the association between adherence to the 2015–2020 Dietary Guidelines for Americans (DGA), measured by Healthy Eating Index (HEI)-2015, and cognitive function remains unclear. This study aims to explore whether HEI-2015 is associated with various cognitive domains and whether such association is modified by age, gender, or ethnicity in the US adults aged 60 years or older using data from the National Health and Nutrition Examination Survey (NHANES) 2011–2014.

Methods

HEI-2015 scores were calculated from 24-h dietary recall interviews. Cognitive function was evaluated by Digit Symbol Substitution Test (DSST, a measure of processing speed), Animal Fluency Test (AFT, a measure of executive function), a subtest from Consortium to Establish a Registry for Alzheimer’s disease (CERAD, a measure of memory), and a composite-z score calculated by summing z scores of individual tests. The associations between HEI-2015 scores and cognitive performance were explored using multiple linear regression models.

Results

A total of 2450 participants aged 60 years or older were included. Participants with higher HEI-2015 scores were more likely to have higher DSST, AFT as well as composite-z scores (P<0.05). Significant interaction effects were identified between HEI-2015 and ethnicity in specific cognitive domains (Pinteraction<0.05). Among HEI-2015 components, higher intakes of whole fruits and seafood and plant protein were associated with better cognitive performance (P<0.05).

Conclusion

Higher adherence to DGA is associated with better cognitive performance, especially regarding processing speed and executive function among the US adults aged 60 years or older.
Multivariate analysis of factors associated with spinal cord area in single-door cervical laminoplasty with miniplate fixation
Authors: Zhang Ke-rui , Yang Yi , Liu Hao , Wang Bei-yu , Ding Chen , Meng Yang , Rong Xin , Hong Ying
Published: October 2021

Objectives

To explore the factors associated with the increased spinal cord area in single-door cervical laminoplasty (SDCL) with miniplate fixation.

Methods

A retrospective study enrolled 83 patients underwent SDCL with miniplate fixation and the patient characteristics such as age, gender, tobacco use, alcohol use, diabetes mellitus, hypertension, diagnosis, operative level, etc., were obtained. The opening angle, door shaft position and spinal canal area of the patients were measured after surgery. The sagittal canal diameter (SCD), the C2–7 Cobb angle, the cervical curvature index (CCI), the range of motion (ROM) and the spinal canal area were measured before and after operation. The increased cervical spinal cord area was also measured before and after surgery, and the correlation between the above indicators and the increased cervical spinal cord area was studied through Pearson’s correlation analysis and multivariate logistic regression analysis.

Results

There were 34 patients in small spinal cord area increment group (SAI group), 29 patients in middle spinal cord area increment group (MAI group) and 20 patients in large spinal cord area increment group (LAI group). The preoperative diagnosis(P = 0.001), door shaft position (P = 0.008), preoperative spinal canal area (P = 0.004) and postoperative spinal canal area (P = 0.015) were significant different among the 3 groups. The multivariate analysis showed that the preoperative diagnosis (OR = 2.076, P = 0.035), door shaft position (OR = 3.425, P = 0.020) and preoperative spinal canal area (OR = 10.217, P = 0.009) were related to increased spinal cord area.

Conclusions

The preoperative diagnosis, door shaft position and preoperative spinal canal area might be associated with increased spinal cord area after cervical laminoplasty with miniplate fixation. Preoperative symptoms are mostly caused by compression of the spinal cord, so spinal cord area enlargement can bring a better recovery in patients alongside long-term. Spine surgeons should pay more attention to the accuracy of the preoperative diagnosis, the preoperative measurement of spinal canal area and the door shaft position during the operation.
NEUROD1 mutation in an Italian patient with maturity onset diabetes of the young 6: a case report
Authors: Brodosi Lucia , Baracco Bianca , Mantovani Vilma , Pironi Loris
Published: October 2021

Background

Maturity Onset Diabetes of the Young (MODY) is a monogenic, autosomal, dominant disease that results in beta-cells dysfunction with consequent hyperglycaemia. It represents a rare form of diabetes (1–2% of all the cases).

Sulphonylureas (SUs) represent the first-line treatment for this form of diabetes mellitus.

NEUROD1 is expressed by the nervous and the pancreatic tissues, and it is necessary for the proper development of beta cells. A neurogenic differentiation factor 1 (NEUROD1) gene mutation causes beta-cells dysfunction, inadequate insulin secretion, and hyperglycaemia (MODY 6).

Case presentation

We have documented a new missense mutation (p.Met114Leu c.340A > C) of the NEUROD1 gene, pathogenetic for diabetes mellitus, in a 48 years-old man affected by diabetes since the age of 25 and treated with insulin basal-bolus therapy. Unfortunately, an attempt to replace rapid insulin with dapagliflozin has failed. However, after the genetic diagnosis of MODY6 and treatment with SUs, he was otherwise able to suspend rapid insulin and close glucose monitoring. Interestingly, our patient had an early onset dilated cardiomyopathy, though no data about cardiac diseases in patients with MODY 6 are available.

Conclusions

Diagnostic criteria for MODY can overlap with other kinds of diabetes and most cases of genetic diabetes are still misdiagnosed as diabetes type 1 or 2. We encourage to suspect this disease in patients with a strong family history of diabetes, normal BMI, early-onset, and no autoimmunity. The appropriate therapy simplifies disease management and improves the quality of the patient’s life.
High pretreatment systemic immune-inflammation index values are associated with diminished short-term success after temporomandibular joint arthrocentesis procedure
Authors: Somay Efsun , Yilmaz Busra
Published: October 2021

Background

The systemic immune-inflammation index (SII) has been demonstrated to be a valid biomarker of a patient's immunological and inflammatory state, with the ability to accurately predict outcomes in a variety of disease conditions. In the absence of comparable studies, we intended to examine the relevance of pretreatment SII in predicting the success rates of temporomandibular joint arthrocentesis (TMJA) at 1-week, 1-month, and 6-month periods, defined as maximum mouth opening (MMO) > 35 mm and VAS ≤ 3.

Methods

A sum of 136 patients with disc displacement without reduction (DDwo-red) who underwent TMJA was included. For each patient, pre-TMJA SII was calculated as; SII = Platelets × neutrophils/lymphocytes. Additionally, baseline MMO and VAS measurements were recorded for each patient. The success criteria of TMJA included MMO > 35 mm and VAS ≤ 3. The optimal pre-TMJA SII cutoff that predicts TMJA success was determined using receiver operating characteristic (ROC) curve analysis. The primary endpoint was the link between the pre-treatment SII and TMJA success (simultaneous achievement of MMO > 35 mm and VAS ≤ 3).

Results

The median pre-TMJA jaw locking duration, maximum mouth opening (MMO), and visual analog score (VAS) were 7 days, 24 mm, and 8, respectively. The overall TMJA success rates were determined as 80.1%, 91.9%, and 69.1% at 1-week, 1-month, and 6-months, respectively. The results of ROC curve analysis exhibited the optimal SII cutoff at 526 (AUC: 67.4%; sensitivity: 66.7%; specificity: 64.2%) that grouped the patients into two subgroups: Group 1: SII ≤ 526 (N = 81) and SII > 526 (N = 55), respectively. Spearman correlation analysis revealed a strong inverse relationship between the pretreatment SII values and the success of TMJA 1-week (rs: − 0.83;P = 0.008) and 1-month, (rs: − 0.89;P = 0.03). Comparative analyses displayed that TMJA success rates at 1-week (87.7% vs. 69.1%;P = 0.008) and 1-month (96.2% vs. 80%;P = 0.03) were significantly higher in the SII ≤ 526 than SII > 526 group, respectively, while the 6-month results favored the SII ≤ 526 group with a trend approaching significance (P = 0.084).

Conclusion

The current study's findings suggested the SII as a unique independent prognostic biomarker that accurately predicts treatment outcomes for up to 6 months.

Description and evaluation of a French grief workshop for children and adolescents bereaved of a sibling or parent
Authors: Ridley Ashley , Revet Alexis , Raynaud Jean-Philippe , Bui Eric , Suc Agnès
Published: October 2021

Background

Childhood bereavement is common, and is associated with elevated symptoms of grief with distress and impairment. However, few developmentally appropriate interventions to support grieving children are available to date. In Toulouse, France we developed an innovative four-session group intervention to support grieving families and evaluated its feasibility and acceptability.

Methods

The workshop consists of four sessions over 4 months, open to children bereaved of a sibling or parent, and co-facilitated by two mental health professionals. After an intake assessment, children were placed into closed groups according to age and relation to the deceased. The session content was balanced between creative activities and grief-related discussions. Overall satisfaction was evaluated in March-April of 2020 by an 8-question online survey of children and parents having participated between 2011 and 2019. Freeform commentaries were analysed using the thematic synthesis process.

Results

Of the 230 emails sent in March 2020, 46 children and 81 parents agreed to participate (55% response rate). The families reported an overall high level of satisfaction regarding the intervention that was rated as good to excellent. A majority of respondents considered their participation in the workshop helpful and in accordance with their expectations. Most would recommend the workshop to a friend, and would participate again in the group if needed. The group intervention helped reduce social isolation, facilitated grief expression, and supported the creation of a sense of community among bereaved families.

Conclusions

Encouraging community and mutual support among grieving families is fundamental in bereavement care. Our four-session workshop held over 4 months and led by mental health professionals aimed to help reduce social isolation and foster coping skills through artistic creation and group discussion. Our results highlight the potential need for family bereavement support over a longer period and a provision of a variety of services. Our intervention model is feasible for families, and further studies examining its efficacy are warranted.
Cross-cultural training program on mental health care for refugees - a mixed method evaluation
Authors: McDonald Jordanos Tewelde , Dahlin Marie , Bäärnhielm Sofie
Published: October 2021

Background

Refugees tend to have a higher risk of mental ill-health and use mental health services less than the native-born population during their first 10 years in Sweden. Intercultural interactions between refugees and mental health professionals have been described as challenging. Cross-cultural training is proposed as one way to improve care for refugees. Evaluations of such training outcomes are sparse. The overall aim of this study was to evaluate Comprehensive Cross-Cultural Training for mental health care professionals in Stockholm, and to assess training outcomes for participants’ perceived knowledge regarding mental health and care for newly arrived refugee patients, asylum seekers and undocumented refugees. In addition, we analysed the dimensionality of the pre- and post-training questionnaires used.

Methods

An embedded mixed-method design was applied. We used pre-and post-training questionnaires (n = 248) and conducted six focus group discussions (FGDs) with mental health professionals after training. Quantitative data was analysed by t-tests and factor analysis, qualitative data was analysed using thematic content analysis.

Results

Participants experienced gained knowledge and new perspectives in all aspects covered in the training. Training led to participants restructuring their existing knowledge. Those who had reported experience of refugee patients and working with interpreters pre-training in the past month, had higher ratings of perceived knowledge. Post-training, there were no significant changes in perceived knowledge between those with, and those without, experience of refugee patients and working with interpreters. Factor analysis resulted in 3 factors for the pre-training questionnaire, explaining 71% of the covariance, and 4 factors for the post-training questionnaire, explaining 78% of the covariance. Findings from the post-training FGDs, revealed that refugee patients were described as challenging. Also, that training promoted empathy towards refugees and strengthened participants’ professional role.

Conclusions

This cross-cultural training contributed to knowledge development and attitude changes. It was valuable regarding care providers’ professional role. Additional outcomes of the training were that participants not only gained knowledge about refugee mental health care but also restructured their existing knowledge.

Published: October 2021

Background

The liver is an important organ that undertakes the metabolic function of the human body. Liver cancer has become one of the cancers with the highest mortality. In clinic, it is an important work to extract the liver region accurately before the diagnosis and treatment of liver lesions. However, manual liver segmentation is a time-consuming and boring process. Not only that, but the segmentation results usually varies from person to person due to different work experience. In order to assist in clinical automatic liver segmentation, this paper proposes a U-shaped network with multi-scale attention mechanism for liver organ segmentation in CT images, which is called MSA-UNet. Our method makes a new design of U-Net encoder, decoder, skip connection, and context transition structure. These structures greatly enhance the feature extraction ability of encoder and the efficiency of decoder to recover spatial location information. We have designed many experiments on publicly available datasets to show the effectiveness of MSA-UNet. Compared with some other advanced segmentation methods, MSA-UNet finally achieved the best segmentation effect, reaching 98.00% dice similarity coefficient (DSC) and 96.08% intersection over union (IOU).
Early supported hospital discharge for foot disease: a co-design study
Authors: Jessup Rebecca , Hanna Samantha , Kaur Jaspreet , Bayat Iman , Bramston Cassandra
Published: October 2021

Background

There are more than 10,000 admissions each year in Australia for foot disease, with an average length of hospital stay of 26 days. Early supported discharge (ESD) has been shown to improve patient satisfaction and reduce length of stay without increasing the risk of 30-day readmissions. This research aims to gain consensus on an optimal model of early supported discharge for foot disease.

Methods

Three focus groups were held where preliminary components for an early discharge model, as well as inclusion and exclusion criteria, were identified with a purposefully sampled group of medical, nursing, allied health staff and consumers. Two researchers independently systematically coded focus group transcripts to identify components of an ESD model using an iterative constant comparative method. These components then formed the basis of a three phase Delphi study, with all individuals from the focus groups were invited to act as panellists. Panellists rated components for their importance with consensus established as a rating of either essential or very important by ≥80% of the panel.

Results

Twenty-nine experts (including 5 consumers) participated across the two study phases. Twenty-three (3 consumers) participated in the focus groups in phase one. Twenty-eight of the twenty-nine experts participated in the phase 2 Delphi. 21/28 completed round 1 of the Delphi (75% response rate), 22/28 completed round 2 (79% response rate), and 16/22 completed round 3 (72% response rate). Consensus was achieved for 17 (29%) of 58 components. These included changes to the way patients are managed on wards (both location and timeliness of care by the multidisciplinary team) and the addition of new workforce roles to improve co-ordination and management of the patients once they are at home.

Conclusions

A model of early supported discharge that would allow individuals to return home earlier in a way that is safe, acceptable, and feasible may result in improving patient satisfaction while reducing health system burden. Future trial and implementation of the ESD model identified in this study has the potential to make a significant contribution to the experience of care for patients and to the sustainability of the health system.
