BackgroundSelf-management is important for the blood sugar control of middle-aged and elderly Type 2 diabetes mellitus (T2DM) patients, of which diet, exercise, and drug compliance are the most common components. The Information-Motivation-Behavioral Skills Model (IMB) has been widely used in health behavior management and intervention.ObjectiveThe purpose of this study is to develop and validate the Diabetic Self-Management Scale (DSMS) based on the IMB model.MethodsSelf-report survey data was collected from middle-aged and elderly T2DM patients in Zhongmu City, Henan Province, China in November 2021 using convenience sampling. The original DSMS was developed through a literature review and summary of previous similar scales using an inductive approach. Item modification was finished by a panel of specialists. Exploratory factor analysis and confirmatory factor analysis were used to evaluate the reliability, convergent validity, discriminant validity, and criterion validity of DSMS.ResultsFour hundred and sixty nine T2DM patients completed the questionnaire survey. The final DSMS consists of 22 items with three dimensions, including information (five items), motivation (eight items), and behavior skills (nine items). The results of simple factor analysis showed that the KMO value was 0.839, Bartlett spherical test 2 = 3254.872, P &lt; 0.001. The results of confirmatory factor analysis showed that 2/df = 2.261, RMSEA = 0.073, CFI = 0.937, TLI = 0.930, and SRMR = 0.096. The standardized factor loadings of 22 DSMS items were all above 0.6, and the CR values of 3 dimensions were all higher than 0.9. In addition, DSMS also showed good discriminant and criterion validity.ConclusionThe 22-item DSMS has good reliability and validity, and can be used to make diabetic self-management assessment regarding diet, physical activity, and medication among middle-aged and elderly Chinese T2DM patients. DSMS is of moderate length and easy to understand. It can be promoted in China in the future to understand the self-management status of middle-aged and elderly T2DM patients in China.

IntroductionThe long-term impact of COVID-19 on mental health, particularly in relation to socio-economic vulnerabilities, has received little attention. This study reports the prevalence of mental health-related symptoms among previously hospitalized patients after recovery from COVID-19, and its association with socio-economic status (SES).MethodsData collection of this cross-sectional study was conducted during February–April 2021, among previously hospitalized patients with COVID-19 like symptoms, on average six months after their discharge from the hospital. Using DASS-21, a validated scale to document symptoms of depression, anxiety, and stress, information on mental health-related symptoms were recorded from 481 respondents along with sociodemographic and economic information through telephone interviews. Chi-square tests were performed to identify significant group differences. Multinomial logistic regression analyzed the association between the changes in socioeconomic characteristics and mental health-related symptoms. Relative index of inequality (RII), slope index of inequality (SII), and concentration index (CIX) were applied to capture relevant inequalities in relation to mental health-related symptoms.ResultsEleven percent of the respondents reported changes in employment status, nearly half changes in income and expenditure. Forty-five percent reported symptoms of depression, anxiety and/or stress, and 12% reported coexistence of all three symptoms. Women [Adjusted Odds Ratio, AOR: 2.95; 95% Confidence Interval, CI: 1.39–5.68], and those who reported changes in occupation [AOR: 3.04; 95% CI: 1.01–9.08] and expenditure [AOR: 2.46; 95% CI: 1.12–5.37] were more likely to report all three mental health-related symptoms compared to men and those without changes in occupation and expenditure. The older age group was less likely [AOR: 0.96; 95%CI: 0.93–0.99] to report coexistence of all three symptoms compared to their younger counterparts. Negative values of concentration index (CIX) indicate that any one mental health-related symptom was significantly concentrated among those with lower expenditure and poor SES.ConclusionThis study will help in addressing mental health-related challenges after recovery from COVID-19 among the identified vulnerable groups through relevant community-based and clinical response, including counseling services, in Bangladesh and similar LMIC contexts.

Introduction: This study aimed to evaluate the effectiveness of a virtual reality based intervention in processing speed and working memory in students with ADHD symptomatology.Methods: A randomized experimental study was conducted, with a sample consisting of 25 adult participants recruited from the Escola Superior de Saúde do Politécnico do Porto. The participants were allocated into two groups: a passive control group and an intervention group that completed 10 sessions using virtual reality-based games from the Enhance VR app. The intervention included 6 games: Whack-a-mole, Shuffled, Assembly, React, Memory Wall, and Maestro. The participants underwent pre- and post-intervention evaluations using the Southwestern Assessment of Processing Speed (SWAPS) and the Sequence of Letters and Numbers and Spatial Location of the Wechsler Adult Intelligence Scale - 3rd Edition - WAIS-III. Descriptive statistics were used to characterize the sample and a mixed ANOVA was used to test the effectiveness of the intervention.Results: There was an improvement in the results of processing speed in the group exposed to the intervention (p &lt; 0.001) and the value of the interaction between intervention and time was also significant (p = 0.004). There were no statistically significant differences between the participants’ working memory in the different variables under study, except for the values of the Spatial location test in the experimental group that improved relative to the initial assessment (p = 0.034).Discussion: A virtual reality cognitive training intervention resulted in improvements in the processing speed measures, which were not found in the control group. Although we cannot make the same conclusions regarding working memory, these results suggest that the VR intervention resulted in progress in the experimental group, possibly influenced by the intervention, which should be verified in future studies with longer interventions.

BackgroundHypertensive intracerebral hemorrhage (HICH) is a severe life-threatening disease, and its incidence has gradually increased in recent years. Due to the particularity and diversity of its bleeding sites, the early treatment of hematoma needs to be more meticulous and accurate, and minimally invasive surgery is often one of the measures that are commonly adopted now. The lower hematoma debridement and the navigation template created by 3D printing technology were compared in the external drainage of a hypertensive cerebral hemorrhage. Then the effect and feasibility of the two operations were explicitly evaluated.Material and methodsWe performed a retrospective analysis of all eligible patients with HICH who underwent laser-guided hematoma evacuation or hematoma puncture under 3D-navigated molds at the Affiliated Hospital of Binzhou Medical University from January 2019 to January 2021. A total of 43 patients were treated. Twenty-three patients were treated with laser navigation-guided hematoma evacuation (group A); 20 patients were treated with 3D navigation minimally invasive surgery (group B). A comparative study was conducted between the two groups to evaluate the preoperative and postoperative conditions.ResultsThe preoperative preparation time of the laser navigation group was significantly shorter than that of the 3D printing group. The operation time of the 3D printing group was better than that of the laser navigation group (0.73 ± 0.26 h vs. 1.03 ± 0.27 h P = 0.00070). In the improvement in the short-term postoperatively, there was no statistically significant difference between the laser navigation group and the 3D printing group (Median hematoma evacuation rate P = 0.14); And in the three-month follow-up NIHESS score, there was no significant difference between the two (P = 0.82).ConclusionLaser-guided hematoma removal is more suitable for emergency operations, with real-time navigation and shortened preoperative preparation time; hematoma puncture under a 3D navigation mold is more personalized and shortens the intraoperative time course. There was no significant difference in therapeutic effect between the two groups.

BackgroundColorectal cancer (CRC) is the most common gastrointestinal malignancy and is generally thought to be caused by the transformation of colorectal polyps. It has been shown that early detection and removal of colorectal polyps may reduce the mortality and morbidity of colorectal cancer.ObjectiveBased on the risk factors associated with colorectal polyps, an individualized clinical prediction model was built to predict and evaluate the possibility of developing colorectal polyp.MethodsA case-control study was conducted. Clinical data were collected from 475 patients who underwent colonoscopy at the Third Hospital of Hebei Medical University from 2020 to 2021. All clinical data were then divided into training sets and validation sets by using R software (7:3). A multivariate logistic analysis was performed to identify the factors associated with colorectal polyps according to the training set, and a predictive nomogram was created by R software based on the multivariate analysis. The results were internally validated by receiver operating characteristic (ROC) curves, calibration curves, and externally validated by validation sets.ResultsMultivariate logistic regression analysis showed that age (OR = 1.047, 95% CI = 1.029–1.065), history of cystic polyp (OR = 7.596, 95% CI = 0.976–59.129), and history of colorectal diverticulums (OR = 2.548, 95% CI = 1.209–5.366) were independent risk factors for colorectal polyps. History of constipation (OR = 0.457, 95% CI = 0.268–0.799) and fruit consumption (OR = 0.613, 95% CI 0.350–1.037) were protective factors for colorectal polyps. The nomogram demonstrated good accuracy for predicting colorectal polyps, with both C index and AUC being 0.747 (95% CI = 0.692–0.801). The calibration curves showed good agreement between the predicted risk by the nomogram and real outcomes. Both internal and external validation of the model showed good results.ConclusionIn our study, the nomogram prediction model is reliable and accurate, which can help early clinical screening of patients with high-risk colorectal polyps, improve polyp detection rate, and reduce the incidence of colorectal cancer (CRC).

BackgroundCentralisation of trauma care has been shown to be associated with improved patient outcomes. The establishment of Major Trauma Centres (MTC) and networks in England in 2012 allowed for centralisation of trauma services and specialties including hepatobiliary surgery. We aimed to investigate the outcomes for patients with hepatic injury over the last 17 years at a large MTC in England in relation to the MTC status of the centre.MethodsAll patients who sustained liver trauma between 2005 and 2022 were identified using the Trauma Audit and Research Network database for a single MTC in the East Midlands. Mortality and complications were compared between patients before and after establishment of MTC status. Multivariable logistic regression models were used to determine the odds ratio (OR) and 95% confidence interval (95% CI) for complications according to MTC status, accounting for the potentially confounding variables of age, sex, severity of injuries and comorbidities for all patients, and the subgroup with severe liver trauma (AAST Grade IV and V).ResultsThere were 600 patients; the median age was 33 (IQR 22–52) years and 406/600 (68%) were male. There were no significant differences in 90-day mortality or length of stay between the pre- and post-MTC patients. Multivariable logistic regression models showed both lower overall complications [OR 0.24 (95% CI 0.14, 0.39); p &lt; 0.001] and lower liver-specific complications [OR 0.21 (95% CI 0.11, 0.39); p &lt; 0.001] in the post-MTC period. This was also the case in the severe liver injury subgroup (p = 0.008 and p = 0.002 respectively).ConclusionsOutcomes for liver trauma were superior in the post-MTC period even when adjusted for patient and injury characteristics. This was the case even though patients in this period were older with more comorbidities. These data support the centralisation of trauma services for those with liver injuries.

Published: February 2023

Conventional methods for the detection and differentiation of Bacillus cereus group species have drawbacks mostly due to the complexity of genetic discrimination between the Bacillus cereus species. Here, we describe a simple and straightforward assay based on the detected unamplified bacterial 16S rRNA by DNA nanomachine (DNM). The assay uses a universal fluorescent reporter and four all-DNA binding fragments, three of which are responsible for “opening up” the folded rRNA while the fourth stand is responsible for detecting single nucleotide variation (SNV) with high selectivity. Binding of the DNM to 16S rRNA results in the formation of the 10–23 deoxyribozyme catalytic core that cleaves the fluorescent reporter and produces a signal, which is amplified over time due to catalytic turnover. This developed biplex assay enables the detection of B. thuringiensis 16S rRNA at fluorescein and B. mycoides at Cy5 channels with a limit of detection of 30 × 103 and 35 × 103 CFU/mL, respectively, after 1.5 h with a hands-on time of ~10 min. The new assay may simplify the analysis of biological RNA samples and might be useful for environmental monitoring as a simple and inexpensive alternative to amplification-based nucleic acid analysis. The DNM proposed here may become an advantageous tool for detecting SNV in clinically significant DNA or RNA samples and can easily differentiate SNV under broadly variable experimental conditions and without prior amplification.

Abstract
We attempt to improve the light extraction of AlGaN-based deep-ultraviolet light-emitting diodes (DUV-LEDs) by introducing a highly transparent p-type layer together with reflective Rh/Al p-type electrodes. The p-GaN contact layer is thinned to balance the Ohmic contact and DUV light transmittance, which helps the Rh/Al p-type electrodes realize high reflection as well as good electrical performance. After optimization, the Rh/Al reflective p-type electrodes present reflectance of greater than 70% and specific contact resistivity of 3.75 × 10−4 Ω·cm2. Due to the improvement in the light extraction efficiency, the highest wall-plug efficiency of 278 nm DUV-LEDs is improved by 57% compared to the conventional configuration with Ni/Au as the p-type electrodes.
Quantum beat of heavy-hole and light-hole excitons originating from interband Stark-ladder transitions in a biased GaAs/AlAs superlattice
Authors: Hasegawa Takayuki 
Published: February 2023

Abstract
The letter reports the quantum beat of heavy-hole (HH) and light-hole (LH) excitons originating from interband Stark-ladder transitions in a GaAs/AlAs superlattice. Under the condition that the pump photon energy was well below the LH-related transition energy, only Bloch oscillation was observed. As the pump photon energy was increased, another oscillatory signal with a frequency of ∼6 THz was superimposed. The calculation considering related transitions indicates that the oscillation is due to the quantum beat of HH and LH excitons originating from the interband Stark-ladder transitions between the hole states and the electron state in the first-nearest-neighbor quantum wells.

Abstract
Since the DMSO seriously oxidizes the GeI2 which is one of the ingredients for the Sn/Ge perovskite, it was difficult to make high-quality films by using the conventional DMSO/DMF solvent. We now first report the MASn0.5Ge0.5I3 perovskite solar cells (PSCs) prepared by a simple spin-coating technology. We found that triethanolamine (TEA)/n-methyl pyrrolidone (NMP) does not oxidize the GeI2 and improves the stability of the precursor. The precursor solution with TEA/NMP/DMF gave high-quality perovskite films. The cell gave a power conversion efficiency of 2.18%. This is the first report proving that Sn/Ge PSCs are fabricated by a conventional solution process.

Published: February 2023

Background: The quality of health services cannot be separated from the collaboration of all components of human resources, including nurses. Transformational leadership supported by supervision can also improve the prevention and control of infection risk in order to optimize their work performance. Supervision activities carried out by the head of the room might have a positive impact on nurse commitment.
Aims: The objective of this study is to analyze the influence of supervision and transformational leadership style on nurse compliance in infection risk prevention and control at GMIBM (Gereja Masehi Injili at Bolaang Mongondow) Monompia General Hospital, Kotamobagu, Indonesia.
Methods: This original research used an analytic observational with a quantitative approach and a cross sectional study design. A total of 72 nurses who worked at GMIBM Monompia Kotamobagu General Hospital, Kotamobagu Regency, Indonesia, was selected in August 2022 using a total sampling technique based on the data from the human resources division. Two combined questionnaires were distributed to define the leader supervision (20 questions) and the nurses' compliance and their transformational leadership styles (18 questions) for prevention and control the infection risks. The results of this study were analyzed using SPSS Software (univariate and bivariate parameters).
Results: This study shows that a sufficient supervision frequency (59.7%) among the participated nurses. We identify there were four transformational leadership styles among the nurses at the selected hospital: Ideal influence (33.3%), Inspirational motivation (27.8%), Individual consideration (20.8%) and Intellectual stimulation (18.1%). Moreover, the majority of nurses performed good compliance in the preventing and controlling the infection risks (80.6%). The lack of compliance might be significantly resulted by the leader supervisions (p-value: 0.002). By the bivariate analysis, this study suggested that there is a relationship between transformational leadership style and compliance (p value: 0.001). We also noticed that the leader supervision and transformational leadership style are moderating variables to strengthen the nurse compliance (R Square = 0.336).
Conclusion : This present study strongly suggested the hospital manager and head departments to pay attention to the two strong factors (Supervision and transformational leadership style) affecting the nurses compliance in updating and implementing the prevention and risk control programs.
