Abstract
Background
Older patients are increasingly showing multi-comorbidities, including advanced chronic diseases. When admitted to the emergency department (ED), the decision to pursue life-prolonging treatments or to initiate a palliative care approach is a challenge for clinicians. We test for the first time the diagnostic accuracy of the Supportive and Palliative Care Indicators Tool (SPICT) in the ED to identify older patients at risk of deteriorating and dying, and timely address palliative care needs.

Methods
We conducted a prospective bicentric cohort study on 352 older patients (≥ 75 years) admitted to two EDs in Belgium between December 2019 and March 2020 and between August and November 2020. SPICT (French version, 2019) variables were collected during the patients’ admission to the ED, along with socio-demographic, medical and functional data. The palliative profile was defined as a positive SPICT assessment. Survival, symptoms and health degradation (≥ 1 point in ADL Katz score or institutionalisation and death) were followed at 12 months by phone. Main accuracy measures were sensitivity, specificity and likelihood ratios (LR) as well as cox regression, survival analysis using the Kaplan Meier method, and ordinal regression.

Results
Out of 352 patients included in the study (mean age 83 ± 5.5 years, 43% male), 167 patients (47%) had a positive SPICT profile. At one year follow up, SPICT positive patients presented significantly more health degradation (72%) compared with SPICT negative patients (35%, p < 0.001). SPICT positivity was correlated with 1-year health degradation (OR 4.9; p < 0.001). The sensitivity and specificity of SPICT to predict health degradation were 0.65 (95%CI, 0.57–0.73) and 0.72 (95%CI, 0.64–0.80) respectively, with a negative LR of 0.48 (95%CI, 0.38–0.60) and a positive LR of 2.37 (1.78–3.16). The survival time was shorter in SPICT positive patients than in SPICT negative ones (p < 0.001), the former having a higher 1-year mortality rate (HR = 4.21; p < 0.001).

Conclusions
SPICT successfully identifies older patients at high risk of health degradation and death. It can support emergency clinicians to identify older patients with a palliative profile and subsequently initiate a palliative care approach with a discussion on goals of care.

AbstractBackgroundWith the increasing number of young women surviving cancer and a growing trend among highly educated women to postpone childbearing for educational or professional pursuits, there is a rising demand for egg freezing services to ensure a successful pregnancy. This study aims to assess the knowledge and beliefs surrounding oocyte cryopreservation, both for medical and social reasons, among female students in Tehran, Iran.MethodsAn online cross-sectional survey was carried out from March to August of 2022, involving a total of 1279 childless students pursuing master’s and doctoral degrees at universities in Tehran. The participants were between the ages of 18 and 38. Knowledge and beliefs about medical and social oocyte cryopreservation were assessed through Fertility Preservation Survey (FPS) instrument.ResultsThe mean age of the participants was 26.38 ± 4.9. The majority of students expected to be “30–34 years” when they become pregnant with their first child (41.1%, M: 30.3 ± 4.13 years) and “35–39 years” when they give birth to their last child (46.7%, M: 35.28 ± 4.18 years). The students agreed with preserving fertility with medical (93.3%) and social (86.9%) indications and believed the medical (95.1%) and social (87.4%) costs of cryopreservation should be covered by the healthcare system. Among the participants, 75.6% considered cost to be a definite or probable factor in their decision to pursue fertility preservation. The oncology team’s recommendation was identified as the most important factor in deciding on medical egg freezing (92.6%, M: 3.46 ± 0.71). The overall correct response rate for the knowledge questions was 57.7%. The majority of participants (95.5%) agreed that physicians should routinely provide information about egg freezing to women of childbearing age during their regular healthcare visits.ConclusionsThe research results revealed that female students in Tehran universities have a positive attitude towards medical and social egg freezing, but lack sufficient knowledge about the ideal timing of childbearing. Health professionals could provide detailed information about fertility preservation and age-related infertility as part of routine healthcare visits or reproductive health planning. Additionally, expanding supportive policies and incentives for childbearing established by the government to cover the costs of fertility preservation would be beneficial.

AbstractBackgroundEvery year, millions of women worldwide suffer in silence from pelvic floor disorders (PFDs) as an annoying health problem. Despite the high prevalence rate and negative effects of PFDs on the quality of life, the validity and reliability of pelvic floor distress inventory-short form (PFDI-20) has not been confirmed for Iranian women of reproductive age. Hence, this study aimed to determine measurement properties of PFDI-20 among women of reproductive age in Tabriz, Iran.MethodsThe current study was cross-sectional research that selected 400 women of reproductive age referring to health centers in Tabriz City, by using cluster random sampling from May 2022 to September 2022. Measurement properties of the Persian version of PFDI-20 were determined and evaluated through five steps, including content and face validity within two quantitative and qualitative parts, structural validity by using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), and reliability testing through internal consistency, test-retest reliability, and measurement error. Moreover, ceiling and floor effects were investigated.ResultsIn this research, CVI (content validity index) and CVR (content validity ratio) of PFDI-20 equaled 0.94 and 0.97, respectively. In addition, the EFA process was applied to 20 items and derived the structure of three factors, which explained 58.15% of the total variance. In CFA phase, values of fit indicators (RMSEA = 0.07, SRMR = 0.07, TLI = 0.97, CFI = 0.99, x2/df = 3.19) confirmed the model validity. To determine reliability, Cronbach’s alpha = 0.84; McDonald’s omega (95% CI) = 0.84 (0.82 to 0.87) and Intraclass Correlation Coefficient (95% CI) = 0.98 (0.97 to 0.99) were obtained. Also, the SEM was 2.64, and the SDC indicating the smallest individual change was 8.91. Regarding the inventory feasibility, the ceiling effect was not observed in total value and subscales, while the floor effect in the total score of PFDI-20 equaled 24.0. The latter rate equaled 45.8, 38.3, and 50.8 for subscales POPDI-6, CRADI-8, and UDI-6, respectively.ConclusionsPersian version of PFDI-20 is a valid and reliable scale used to evaluate PFDs in Iranian women of reproductive age. Healthcare professionals can use this scale to screen PFDs, and researchers can consider it a reliable tool for their studies.

AbstractBackgroundThere is a serious shortage of clinical pharmacists in Xinjiang, China. A six-month to one-year on-the-job training programme can rapidly transition nonclinical pharmacists into clinical pharmacists to resolve this issue. However, not all nonclinical pharmacists are willing to become clinical pharmacists, and many factors may influence their willingness. This study aims to assess the transformation intention of nonclinical hospital pharmacists and the contributing elements to make recommendations to accelerate the transformation of hospital pharmacists to clinical pharmacists.MethodsCross-sectional survey was conducted in secondary and tertiary hospitals in Xinjiang. Taking 14 prefectures in Xinjiang as a cluster, 34 hospitals were randomly selected. By snowball sampling, the heads of pharmaceutical departments introduced non-clinical pharmacists to participate in an anonymous questionnaire survey, which included 41 questions about basic demographic information, cognition and attitudes towards pharmaceutical care, potential factors and willingness to transform, and it took an average of 10 min to complete. Using multifactor logistic regression, the contributing elements of transformation intention were analysed.ResultsThe survey was conducted from May to October 2022. 338 valid responses were obtained, with a response rate of 91.85% and a willingness to transform rate of 81.67%. There were significant differences in the willingness to transform among nonclinical pharmacists of different ages (P < 0.05), marital statuses (P < 0.05), years of employment (P < 0.05), and technical titles (P < 0.05). There were significant differences between the two groups in the following four aspects: whether the setting of human resources in the pharmaceutical department was reasonable (P < 0.05), the educational level of clinical pharmacists (P < 0.05), the higher salary level of clinical pharmacists (P < 0.05), and whether they had experience in pharmaceutical care (P < 0.05). There was a significant difference in the total score of the pharmaceutical care attitude scale (P < 0.05) between the willing and unwilling groups. The results of multivariate logistic regression analysis revealed that the experience of providing pharmaceutical care (OR = 4.601, 95% CI: 1.13–18.69,P < 0.05) and attitude towards pharmaceutical care (OR = 3.302, 95% CI: 1.19–9.19,P < 0.05) had a statistically significant influence on the transformation intention of nonclinical pharmacists.ConclusionsOne-fifth of nonclinical pharmacists were unwilling to transition to clinical pharmacists. The attitude towards and experience of pharmaceutical care affected pharmacists’ transformation intention, so the suggestion is proposed to promote the transformation of nonclinical pharmacists into clinical pharmacists.

Published: June 2023

Abstract
Background
Type 2 diabetes is associated with an increased risk of developing cardiovascular events. Previous studies have reported that advanced glycation end products (AGEs) were related to cardiovascular events in type 2 diabetes. However, data on associations between long-term AGEs and cardiovascular events in type 2 diabetes are lacking. This study aimed to determine whether a long-time shift in the levels of serum AGEs is associated with cardiovascular events in patients with poorly controlled type 2 diabetes.

Methods
Two-time serum methyl-glyoxal-hydroimidazoline (MG-H1) levels were measured in 138 patients with type 2 diabetes whose mean glycated hemoglobin level was 10.1%. We categorized patients whose serum MG-H1 levels were < 2.8 µg/mL at both times as the continuous low MG-H1 group. The primary endpoints of this study were combined cardiovascular events, which were defined as heart disease, peripheral arterial disease, stroke, and all-cause death. Hazard ratios (HRs) for combined cardiovascular events with 95% confidence intervals (CIs) were calculated using the Cox proportional hazard models to compare the outcomes between the continuous low MG-H1 group and others.

Results
The continuous low MG-H1 group was associated with a significantly lower risk than others in combined cardiovascular events after adjusting for possible confounders (HR: 0.50; 95% CI, 0.28–0.87; P = 0.02). Furthermore, the same relationship was observed in patients without a history of cardiovascular events.

Conclusions
Continuous low serum MG-H1 levels are associated with a low frequency of diabetes-related complications in patients with poorly controlled type 2 diabetes.

Published: June 2023

Abstract
Background
Ivermectin (22,23-dihydroavermectin B1a: H2B1a) is an endectocide used to treat worm infections and ectoparasites including lice and scabies mites. Furthermore, survival of malaria transmitting Anopheles mosquitoes is strongly decreased after feeding on humans recently treated with ivermectin. Currently, mass drug administration of ivermectin is under investigation as a potential novel malaria vector control tool to reduce Plasmodium transmission by mosquitoes. A “post-ivermectin effect” has also been reported, in which the survival of mosquitoes remains reduced even after ivermectin is no longer detectable in blood meals. In the present study, existing material from human clinical trials was analysed to understand the pharmacokinetics of ivermectin metabolites and feeding experiments were performed in Anopheles stephensi mosquitoes to assess whether ivermectin metabolites contribute to the mosquitocidal action of ivermectin and whether they may be responsible for the post-ivermectin effect.

Methods
Ivermectin was incubated in the presence of recombinant human cytochrome P450 3A4/5 (CYP 3A4/5) to produce ivermectin metabolites. In total, nine metabolites were purified by semi-preparative high-pressure liquid chromatography. The pharmacokinetics of the metabolites were assessed over three days in twelve healthy volunteers who received a single oral dose of 12 mg ivermectin. Blank whole blood was spiked with the isolated metabolites at levels matching the maximal blood concentration (Cmax) observed in pharmacokinetics study samples. These samples were fed to An. stephensi mosquitoes, and their survival and vitality was recorded daily over 3 days.

Results
Human CYP3A4 metabolised ivermectin more rapidly than CYP3A5. Ivermectin metabolites M1–M8 were predominantly formed by CYP3A4, whereas metabolite M9 (hydroxy-H2B1a) was mainly produced by CYP3A5. Both desmethyl-H2B1a (M1) and hydroxy-H2B1a (M2) killed all mosquitoes within three days post-feeding, while administration of desmethyl, hydroxy-H2B1a (M4) reduced survival to 35% over an observation period of 3 days. Ivermectin metabolites that underwent deglycosylation or hydroxylation at spiroketal moiety were not active against An. stephensi at Cmax levels. Interestingly, half-lives of M1 (54.2 ± 4.7 h) and M4 (57.5 ± 13.2 h) were considerably longer than that of the parent compound ivermectin (38.9 ± 20.8 h).

Conclusion
In conclusion, the ivermectin metabolites M1 and M2 contribute to the activity of ivermectin against An. stephensi mosquitoes and could be responsible for the “post-ivermectin effect”.
The concepts of muscle activity generation driven by upper limb kinematics
Authors: Schmidt Marie D. , Glasmachers Tobias , Iossifidis Ioannis 
Published: June 2023

Abstract
Background
The underlying motivation of this work is to demonstrate that artificial muscle activity of known and unknown motion can be generated based on motion parameters, such as angular position, acceleration, and velocity of each joint (or the end-effector instead), which are similarly represented in our brains. This model is motivated by the known motion planning process in the central nervous system. That process incorporates the current body state from sensory systems and previous experiences, which might be represented as pre-learned inverse dynamics that generate associated muscle activity.

Methods
We develop a novel approach utilizing recurrent neural networks that are able to predict muscle activity of the upper limbs associated with complex 3D human arm motions. Therefore, motion parameters such as joint angle, velocity, acceleration, hand position, and orientation, serve as input for the models. In addition, these models are trained on multiple subjects (n=5 including , 3 male in the age of 26±2 years) and thus can generalize across individuals. In particular, we distinguish between a general model that has been trained on several subjects, a subject-specific model, and a specific fine-tuned model using a transfer learning approach to adapt the model to a new subject. Estimators such as mean square error MSE, correlation coefficient r, and coefficient of determination R2 are used to evaluate the goodness of fit. We additionally assess performance by developing a new score called the zero-line score. The present approach was compared with multiple other architectures.

Results
The presented approach predicts the muscle activity for previously through different subjects with remarkable high precision and generalizing nicely for new motions that have not been trained before. In an exhausting comparison, our recurrent network outperformed all other architectures. In addition, the high inter-subject variation of the recorded muscle activity was successfully handled using a transfer learning approach, resulting in a good fit for the muscle activity for a new subject.

Conclusions
The ability of this approach to efficiently predict muscle activity contributes to the fundamental understanding of motion control. Furthermore, this approach has great potential for use in rehabilitation contexts, both as a therapeutic approach and as an assistive device. The predicted muscle activity can be utilized to guide functional electrical stimulation, allowing specific muscles to be targeted and potentially improving overall rehabilitation outcomes.
Circulating prekallikrein levels are correlated with lipid levels in the chinese population: a cross-sectional study

Published: June 2023

Abstract
Background
Recent evidence has revealed that circulating coagulation factor prekallikrein (PK), an important part of the kallikrein-kinin system, regulates cholesterol metabolism, but the association between serum PK and lipid levels is unclear.

Methods
This cross-sectional study included 256 subjects (aged from 1 month to 90 years) who underwent physical examinations at the First People’s Hospital of Huaihua, China. After overnight fasting, serum was collected for PK and lipid testing. Spearman correlation analysis and multivariable logistic regression analysis were used to analyze the association of PK level with lipid levels and the likelihood risk of hyperlipidemia. The possible threshold value of PK was calculated according to the receiver operating characteristic (ROC) curve.

Results
The median serum PK level was 280.9 µg/mL (IQR 168.0, 377.0), and this level changed with age but not sex. The serum PK level was positively correlated with the serum total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglyceride (TG) levels. A nonlinear relationship was observed between serum PK and high-density lipoprotein cholesterol (HDL-C) levels. The serum PK level was positively correlated with HDL-C when its level was lower than 240 µg/mL and negatively correlated with HDL-C when its level was higher than 240 µg/mL. The regression analysis demonstrated that an elevated serum PK level was significantly associated with the likelihood risk of hypercholesterolemia and hypertriglyceridemia. The ROC curve showed that the possible threshold values of serum PK for hypercholesterolemia and hypertriglyceridemia occurrences were 344.9 µg/mL and 305.7 µg/mL, respectively.

Conclusions
Elevated serum PK levels were significantly associated with the likelihood of hypercholesterolemia and hypertriglyceridemia, and the possible threshold values of PK levels were 344.9 µg/mL and 305.70 µg/mL, respectively, suggesting that higher PK levels may be a risk factor for cardiovascular diseases.

Published: June 2023

Abstract
Background
Kinesiophobia is one of the most common and aversive psychological phenomena among patients after total knee arthroplasty (TKA). This study aimed to identify trajectories of kinesiophobia, examine factors distinguishing these trajectories, and clarify the association between trajectories of kinesiophobia and rehabilitation outcomes.

Methods
In this prospective cohort study, the patients who underwent TKA were recruited between December 2021 and April 2022 from three orthopedic wards of a tertiary hospital in China. Kinesiophobia was measured using the Tampa Scale for Kinesiophobia at baseline (T0), and then at 1 month (T1) and 3 months (T2) after TKA to perform latent class growth analysis. Meanwhile, rehabilitation outcomes were assessed at 3 months after TKA, using the Kessler Psychological Distress Scale, the Hospital for Special Surgery-Knee Scale, Barthel Index, and the Impact on Participation and Autonomy questionnaire.

Results
The four kinesiophobia trajectories identified were as follows: low stable group (n = 120), rapid recovering group (n = 31), slow recovering group (n = 48), and stable moderate group (n = 58). Body mass index, employment status, heart disease, and pain degree significantly predicted trajectory groups (all p < 0.05). Analysis of variance revealed significant differences between the four kinesiophobia trajectories concerning all rehabilitation outcomes, except for the activities of daily living.

Conclusion
Distinct kinesiophobia trajectories were identified, and nurses should assess the kinesiophobia of patients after TKA in the early phase. Patients in the slow recovering group are worthy of a specific focus because of their poor recovery after undergoing TKA. As important sources of psychosocial care, nurses need to customize psychological interventions for patients after TKA depending on each kinesiophobia trajectory.
