AbstractParkinson's disease (PD) is characterized by the progressive loss of dopaminergic neurons in the midbrain, and the stem cell transplantation method provides a promising strategy for the treatment. In these studies, tracking the biological behaviors of the transplanted cells in vivo is essential for a basic understanding of stem cell function and evaluation of clinical effectiveness. In the present study, we developed a novel ultrasmall superparamagnetic iron oxide nanoparticles coating with the polyacrylic acid (PAA) and methoxypolyethylene glycol amine (PEG) by thermal decomposition method and a two-step modification. The USPIO-PAA/PEG NPs have a uniform diameter of 10.07 ± 0.55 nm and proper absorption peak of the corresponding ligands, as showed by TEM and FTIR. MTT showed that the survival of cells incubated with USPIO-PAA/PEG NPs remained above 96%. The synthesized USPIO-PAA/PEG had a good relaxation rate of 84.65 s−1 Mm−1, indicating that they could be efficiently uptake and traced by MRI. Furthermore, the primary human adipose-derived stem cells (HADSCs) were characterized, labeled with USPIO-PAA/PEG and transplanted into the striatum of 6-hydroxydopamine (6-OHDA)-induced PD rat models. The labeled cells could be traced by MRI for up to 3 weeks after the transplantation surgery; moreover, transplantation with the labeled HADSCs significantly attenuated apomorphine-induced rotations in PD models and increased the number of the dopaminergic neurons in the substania nigra. Overall, the development of USPIO-PAA/PEG NPs provides a promising tool for in vivo tracing technique of cell therapy and identifies a novel strategy to track stem cells with therapeutic potential in PD.

Abstract
Background
Basal cell carcinoma of the prostate is a relatively rare entity. Their evolution is characterized by the frequency of local and/or distant relapses. Due to their rarity, the treatment is not consensual in the literature. We report here a case of Basal cell carcinoma of the prostate in a 40-year-old patient.

Case presentation
Our patient initially presented an obstructive lower urinary tract symptoms with a normal initial level of prostate specific antigen (PSA) test (3.5 ng/m). The transurethral resection of the prostate (TURP) was in favor of a prostatic basal cell carcinoma with its specific anatomopathological and immunohistochemical characteristics. The prostatic MRI and thoraco-abdominal CT realized after the TURP revealed a tumoral lesion of the prostatic peripheral zone with extra-capsular extension combined with right seminal vesicle invasion and a suggestion of posterior bladder wall adherence. No evidence of visceral or nodal metastases at this point. Considering the tumor being locally advanced, a concurrent chemoradiotherapy with intensity modulated technique was indicated after a multidisciplinary meeting with a 70 Gy total target dose delivered in 35 fractions and weekly Cisplatin. A year and a half after, he developed a cerebellous metastases revealed by intracranial hypertension with no other visceral lesion and complete local remission with the disappearance of the lower urinary tract symptoms and the pain and the appearance of a prostatic atrophy. The PSA level was still on the upper limit of normal. He underwent metastasectomy, and the anatomopathological study was in favor of a cerebellous metastasis of the known BCC. The patient presented postoperatively paraparesis of lower limbs with balance problems for which he was placed in palliative care with indication of postoperative radiation therapy in case of improvement of his general condition. He did not recover and deceased three months later.

Conclusions
The prostatic basal cell carcinoma is a rare aggressive entity often non-evoked at the clinical or radiological stages because of its unspecific appearance. The diagnostic of these tumors is based on histological examination and a large immunohistochemistry panel. Given its scarity, very few data is available for locally advanced non-metastatic stages treated by radiation therapy. We assess here a good local response with concurrent chemoradiation therapy.

AbstractBackgroundThe International Classification of Functioning, Disability, and Health (ICF) Generic-30 (Rehabilitation) Set is a tool used to assess the functioning of a clinical population in rehabilitation. The ICF Generic-30 consists of nine ICF categories from the component “body functions” and 21 from the component “activities and participation”. This study aimed to develop a rating reference guide for the nine body function categories of the ICF Generic-30 Set using a predefined, structured process and to examine the interrater reliability of the ratings using the rating reference guide.MethodsThe development of the first version of the rating reference guide involved the following steps: (1) a trial of rating patients by several raters; (2) cognitive interviews with each rater to analyze the thought process involved in each rating; (3) the drafting of the rating reference guide by a multidisciplinary panel; and (4) a review by ICF specialists to confirm consistency with the ICF. Subsequently, we conducted a first field test to gain insight into the use of the guide in practice. The reference guide was modified based on the raters’ feedback in the field test, and an inter-rater reliability test was conducted thereafter. Interrater agreement was evaluated using weighted kappa statistics with linear weights.ResultsThe first version of the rating reference guide was successfully developed and tested. The weighted kappa coefficient in the field testing ranged from 0.25 to 0.92. The interrater reliability testing of the rating reference guide modified based on the field test results yielded an improved weighted kappa coefficient ranging from 0.53 to 0.78. Relative improvements in the weighted kappa coefficients were observed in seven out of the nine categories. Consequently, seven out of nine categories were found to have a weighted kappa coefficient of 0.61 or higher.ConclusionsIn this study, we developed and modified a rating reference guide for the body function categories of the ICF Generic-30 Set. The interrater reliability test using the final version of the rating reference guide showed moderate to substantial interrater agreement, which encouraged the use of the ICF in rehabilitation practice.

Published: June 2021

Abstract
Background
Urinary tract infections (UTIs) are the most common infections caused by Gram-negative bacteria and represent a major healthcare burden. Carbapenem-resistant (CR) strains of Enterobacterales and non-lactose fermenting pathogens further complicate treatment approaches.

Methods
We conducted a retrospective analysis of the US Premier Healthcare Database (2014–2019) in hospitalised adults with a UTI to estimate the healthcare burden of Gram-negative CR UTIs among patients with or without concurrent bacteraemia.

Results
Among the 47,496 patients with UTI analysed, CR infections were present in 2076 (4.4%). Bacteraemia was present in 24.5% of all UTI patients, and 1.7% of these were caused by a CR pathogen. The most frequent CR pathogens were Pseudomonas aeruginosa (49.4%) and Klebsiella pneumoniae (14.2%). Patients with CR infections had a significantly longer hospital length of stay (LOS) (median [range] 8 [5–12] days vs 6 [4–10] days, P < 0.001), were less likely to be discharged home (38.4% vs 51.0%, P < 0.001), had a higher readmission rate (22.6% vs 13.5%, P < 0.001), and had greater LOS-associated charges (mean US$ 91,752 vs US$ 66,011, P < 0.001) than patients with carbapenem-susceptible (CS) infections, respectively. The impact of CR pathogens was greater in patients with bacteraemia (or urosepsis) and these CR urosepsis patients had a significantly higher rate of mortality than those with CS urosepsis (10.5% vs 6.0%, P < 0.001).

Conclusions
Among hospitalised patients with UTIs, the presence of a CR organism and bacteraemia increased the burden of disease, with worse outcomes and higher hospitalisation charges than disease associated with CS pathogens and those without bacteraemia.

Published: June 2021

Abstract
Background
Since subjects with Rett syndrome (RTT) focus their attention mainly on the faces of people with whom they interact, in this study the role of a human-like smart interactive agent (an avatar) in enhancing cognitive processes is examined. More in depth, this study aimed to understand if, and to what extent, the use of an avatar can improve attention and memory abilities in subjects with RTT.

Method
Thirty-six subjects with RTT participated in the study. All participants performed over-selectivity and memory tasks, for a total of six trials. These trials were randomly presented in two different conditions: with and without virtual avatar.

Results
The results indicated that the participants improved their attention and memory abilities when they performed the tasks with the avatar. There were no improvements when they performed the tasks without the avatar.

Discussion
The results were discussed considering the relationship between motivation, attention and memory in RTT.

Abstract
Background
Human Papillomavirus (HPV) vaccine uptake is low among East African adolescents in the US. Adolescents’ preferences influence HPV vaccine decisions, yet few interventions exist that address East African adolescents’ beliefs about HPV vaccines. We describe a multi-step process on how to create a theory-based comic book by integrating empirical findings, theory and focus group data from East African parents in the US.

Methods
Our multi-methods process included conducting focus groups with Somali, Ethiopian, and Eritrean mothers (n = 30) to understand mothers and adolescents socio-cultural beliefs and information needs about the HPV vaccine, creating comic book messages integrating the focus group findings, and assessing the acceptability of the finalized comic book among Somali, Ethiopian, and Eritrean adolescents (n = 134).

Results
We identified categories around socio-cultural beliefs (such ethnic representation and concerns about pork gelatin in vaccines), HPV vaccine information needs, and diffusion of information. We then mapped the categories to theoretical constructs and operationalized them into the comic book. Finally, we describe the overall acceptability of the comic book and specifics on comic book structure, appeal of characters, and message relevance.

Conclusions
A rigorous multi-step process that integrates theory and focus group data can help create culturally appropriate health messages that can educate and appeal to the community.

Published: June 2021

Abstract
Background
Mental health is affected by both genetic and environmental factors. However, previous studies have showed conflict findings about the role of lifestyle and little is known about the situation of the Chinese population. The purpose of this study was to explore the relationship between the frequency of food consumption, physical exercise condition and mental health, as well as factors related to mental stress in Chinese.

Methods
We recruited 8160 residents who had health examinations in a public hospital during June 2016 to May 2018. Demographic characteristics, the frequency of food consumption, physical exercise condition and mental health status was collected by a questionnaire. We estimated the association using the odds ratio (OR) and 95% confidence interval (CI) based on Binary or ordinal logistic regression models. A classification and regression tree (CART) demonstrated the prediction of the value of a target variable based on other values.

Results
The logistic regression model and classification tree model both found that the frequency of fresh vegetables or fruit and fried foods consumption and the current state of drinking alcohol were related to mental stress. The degree of mental stress reduced significantly with increasing consumption of fish (OR = 0.80, 95% CI: 0.71–0.90) and regular exercise (OR = 0.55, 95% CI:0.48–0.64) in females and increased consumption of fish (OR = 0.55, 95% CI: 0.48–0.64) and cereal crop (OR = 0.77, 95% CI: 0.68–0.89), fish (OR = 0.87, 95%CI:0.77–0.96) and regular exercise (OR = 0.61, 95%CI:0.53–0.70) in males. On the contrary, the frequency of consumption of desserts (OR = 1.43, 95% CI: 1.26–1.62) and the current of drinking alcohol (OR = 1.47, 95%CI:1.21–1.79) in females and meat (OR = 1.47, 95%CI: 1.31–1.65), pickled and smoked food (OR = 1.18, 95%CI:1.05–1.32) and the current state of drinking alcohol (OR = 1.25, 95%CI:1.12–1.40) in males were related to an increased risk of mental health.

Conclusions
Our study showed that both the frequency of some food consumption and physical exercise condition were associated with mental health and affected the degree of stress, which provided novel insights into interventions.

Published: June 2021

Abstract
Background
A persistent research finding in Finland and elsewhere has been variation in medical practices both between and within countries. Variation seems to exist especially if medical decision making involves discretion and the best treatment cannot be identified unambiguously. This is true for hysterectomy when performed for benign causes. The aim of the current study was to investigate regional trends in hysterectomy in Finland and the potential convergence of rates over time.

Methods
We used hospital discharge register data on hysterectomies performed, diagnoses, age, and region of residence to examine hospital discharges for women undergoing hysterectomy in 2001–2018 among total female population aged 25 years or older in Finland. We examined hysterectomy rates among biannual cohorts by indication, calculated age-standardised rates and used multilevel models to analyse potential convergence over time.

Results
Altogether 131,695 hysterectomies were performed in Finland 2001–2018. We found a decreasing trend, with the age-adjusted overall hysterectomy rate decreasing from 553/100,000 person years in 2001–2002 to 289/100,000 py in 2017–2018. Large but converging regional differences were found. The correlations between hospital district intercepts and slopes in time ranged from − 0.71 to − 0.97 (p < 0.001) suggesting diminishing variation.

Conclusions
Our findings demonstrate that change in hysterectomy practices and more uniformity across regions are achievable goals. Regional variation still exists suggesting differences in medical practices.

Published: June 2021

Abstract
Background
Transitions in healthcare delivery, such as the rapidly growing numbers of older people and increasing social and healthcare needs, combined with nursing shortages has sparked renewed interest in differentiations in nursing staff and skill mix. Policy attempts to implement new competency frameworks and job profiles often fails for not serving existing nursing practices. This study is aimed to understand how licensed vocational nurses (VNs) and nurses with a Bachelor of Science degree (BNs) shape distinct nursing roles in daily practice.

Methods
A qualitative study was conducted in four wards (neurology, oncology, pneumatology and surgery) of a Dutch teaching hospital. Various ethnographic methods were used: shadowing nurses in daily practice (65h), observations and participation in relevant meetings (n=56), informal conversations (up to 15 h), 22 semi-structured interviews and member-checking with four focus groups (19 nurses in total). Data was analyzed using thematic analysis.

Results
Hospital nurses developed new role distinctions in a series of small-change experiments, based on action and appraisal. Our findings show that: (1) this developmental approach incorporated the nurses’ invisible work; (2) nurses’ roles evolved through the accumulation of small changes that included embedding the new routines in organizational structures; (3) the experimental approach supported the professionalization of nurses, enabling them to translate national legislation into hospital policies and supporting the nurses’ (bottom-up) evolution of practices. The new roles required the special knowledge and skills of Bachelor-trained nurses to support healthcare quality improvement and connect the patients’ needs to organizational capacity.

Conclusions
Conducting small-change experiments, anchored by action and appraisal rather than by design, clarified the distinctions between vocational and Bachelor-trained nurses. The process stimulated personal leadership and boosted the responsibility nurses feel for their own development and the nursing profession in general. This study indicates that experimental nursing role development provides opportunities for nursing professionalization and gives nurses, managers and policymakers the opportunity of a ‘two-way-window’ in nursing role development, aligning policy initiatives with daily nursing practices.

Abstract
Background
Karyomegalic interstitial nephritis (KIN) is a rare disease entity first described by Burry in 1974. The term KIN was introduced by Mihatsch et al. in 1979. KIN is characterized by chronic tubulointerstitial nephritis associated with enlarged tubular epithelial cell nuclei, which leads to a progressive decline of renal function. The prevalence of this disease is less than 1% of all biopsies, and its pathogenesis is unclear. KIN results from mutations in FAN1 (FANCD2/FANCI-Associated Nuclease 1), a gene involved in the DNA damage response pathway, particularly in the kidney. In this study, we report two Tunisian consanguineous families with KIN caused by mutations in the FAN1 gene.

Methods
Direct sequencing of the coding regions and flanking intronic sequences of the FAN1 gene was performed in three affected members. Three prediction programs (Polyphen-2 software, SIFT, and MutationTaster) were used to predict the functional effect of the detected variations.

Results
Two causative frameshift variants in the FAN1 gene were identified in each family: The previously described frameshift mutation c.2616delA (p.Asp873ThrfsTer17) and a novel mutation c.2603delT (p.Leu868ArgfsTer22) classified as "pathogenic" according to the American College of Medical Genetics and Genomics (ACMG) guidelines.

Conclusion
To our best knowledge, this is the first Tunisian study involving familial cases of KIN with mutations in the FAN1 gene. We hypothesize that these findings can expand the mutational spectrum of KIN and provide valuable information on the genetic cause of KIN.
SERPINB10 contributes to asthma by inhibiting the apoptosis of allergenic Th2 cells

Published: June 2021

Abstract
Background
Serine peptidase inhibitor, clade B, member 10 (SERPINB10) contributes to allergic inflammation in asthma. However, its role in the T-helper type 2 (Th2) response of allergic asthma is not known. The goal of this study was to unveil the function of SERPINB10 in the Th2 response of allergic asthma and the mechanism by which SERPINB10 affects the viability of Th2 cells.

Methods
Th2 cytokines and serum levels of house dust mite (HDM)-specific IgE in bronchoalveolar lavage fluid were examined by ELISA in an HDM-induced asthma model. The number and apoptosis of Th1 and Th2 cells in mouse lungs were measured by flow cytometry. Naïve CD4 T cells from patients with asthma were cultured under appropriate polarizing conditions to generate Th1 and Th2 cells. SERPINB10 expression in polarized Th1 and Th2 cells was quantified by real-time reverse transcription-quantitative polymerase chain reaction. SERPINB10 expression was knocked down in human CD4 T cells with lentivirus.

Results
Knockdown of SERPINB10 expression significantly diminished HDM-induced Th2 cytokine secretion and level of HDM-specific IgE. After HDM exposure, SERPINB10-knockdown mice had diminished numbers of Th2 cells, but similar numbers of Th1 cells, compared with those in negative-control mice. Th2 cells of SERPINB10-knockdown mice were more susceptible to apoptosis than that of control mice. Stimulating T-cell receptors (TCRs) with anti-CD3 antibody caused upregulation of SERPINB10 expression in polarized Th2 cells, but not polarized Th1 cells. Knockdown of SERPINB10 expression resulted in fewer numbers and greater apoptosis of polarized Th2 cells.

Conclusion
Our results suggest that SERPINB10 may contribute to allergic inflammation and the Th2 response of asthma by inhibiting the apoptosis of Th2 cells.
