Abstract
Recent demonstrations of room-temperature lasing in optically pumped GeSn show promise for future CMOS compatible lasers for Si-photonics applications. However, challenges remain for electrically pumped devices. Investigation of the processes that limit device performance is therefore vital in aiding the production of future commercial devices. In this work, a combined experimental and modelling approach is utilised to explore the dominant loss processes in current devices. By manipulating the band structure of functioning devices using high hydrostatic pressure techniques at low temperature, the dominant carrier recombination pathways are identified. This reveals that 93± 5% of the threshold current is attributable to defect-related recombination at a temperature, T = 85 K. Furthermore, carrier occupation of L-valley states (carrier leakage) is responsible for 1.1± 0.3% of the threshold current, but this sharply increases to 50% with a decrease of just 30 meV in the L- Γ separation energy. This indicates that thermal broadening of a similar order may reproduce these adverse effects, limiting device performance at higher temperatures. Temperature dependent calculations show that carrier occupation of indirect valley L-states strongly affects the transparency carrier density and is therefore very sensitive to the Sn composition, leading to an effective operational temperature range for given Sn compositions and strain values. Recommendations for future device designs are proposed based on band structure and growth optimisations.

Abstract
This report describes the case of an 18-year-old Micronesian pregnant woman at 32 weeks gestation, initially presumed to have eclampsia but later diagnosed with reversible cerebral vasoconstriction syndrome (RCVS). She presented with seizures, altered mental status, nystagmus, lower extremity weakness, and absent reflexes. An extensive workup ruled out infectious and autoimmune causes, but a computed tomography angiogram (CTA) revealed severe cerebral vasoconstriction. Treatment included levetiracetam, intravenous magnesium, and nimodipine. The case highlights the challenge of differentiating RCVS from eclampsia in the postpartum period, emphasizing the importance of considering alternative diagnoses and brain CTA when RCVS is suspected, with calcium channel blockers potentially contributing to favorable neurological outcomes.

Abstract
Pneumocystis, an important opportunistic fungal pathogen that parasitizes in multiple mammalian lungs, may cause life-threatening Pneumocystis pneumonia (PCP) and even death among immunocompromised individuals. With the rapid development of high-throughput sequencing and multi-omics technologies, systematic comparative analyses of genome, transcriptome, and whole-genome sequencing results demonstrate that Pneumocystis is a type of obligate biotrophic fungi, and requires obtaining nutrition from hosts. In addition, sexual reproduction is an essential process for Pneumocystis survival, production and transmission, and asexual reproduction facilitates Pneumocystis survival, which provides new insights into understanding of the whole developmental process of Pneumocystis in the host lung and inter-host transmission of Pneumocystis. This review summarizes the advances in the reproduction mode of Pneumocystis and underlying mechanisms, which provides insights into prevention and treatment of PCP, notably for the prophylaxis against nosocomial transmission of PCP.

Abstract
Swertia bimaculata (SB) is a medicinal herb in China having an array of therapeutic and biological properties. This study aimed to explore the attenuating effect of SB on carbon tetrachloride (CCl4) induced hepato-toxicity by regulation of gut microbiome in ICR mice. For this purpose, CCl4 was injected intraperitoneally in different mice groups (B, C, D and E) every 4th day for a period of 47 days. Additionally, C, D, and E groups received a daily dose (50 mg/kg, 100 mg/kg, and 200 mg/kg respectively) of Ether extract of SB via gavage for the whole study period. The results of serum biochemistry analysis, ELISA, H&E staining, and sequencing of the gut microbiome, indicated that SB significantly alleviates the CCl4-induced liver damage and hepatocyte degeneration. The serum levels of alanine transaminase, aspartate aminotransferase, malondialdehyde, interleukin 1 beta and tumor necrosis factor-alpha were significantly lower in SB treated groups compared to control while levels of glutathione peroxidase were raised. Also, the sequencing data indicate that supplementation with SB could restore the microbiome and its function in CCl4-induced variations in intestinal microbiome of mice by significantly downregulating the abundances of pathogenic intestinal bacteria species including Bacteroides, Enterococcus, Eubacterium, Bifidobacterium while upregulating the levels of beneficial bacteria like Christensenella in the gut. In conclusion, we revealed that SB depicts a beneficial effect against hepatotoxicity induced by CCl4 in mice through the remission of hepatic inflammation and injury, through regulation of oxidative stress, and by restoring gut microbiota dysbiosis.

Abstract
AIMS To assess time to, cumulative incidence of, and functional benefit of achieving sustained ≥2-step Diabetic Retinopathy Severity Scale (DRSS) improvement in diabetic macular oedema (DMO). METHODS Post hoc analysis of VISTA/VIVID including eyes with DMO treated with intravitreal aflibercept injections (IAI), 2 mg q4 weeks (2q4, n = 250) or q8 weeks after 5 monthly doses (2q8, n = 249), or laser control (n = 249). Changes from baseline in best-corrected visual acuity (BCVA) and central subfield thickness (CST) were evaluated in sustained (≥2 consecutive visits) DRSS subgroups (≥1-step worsening, no change, ≥2-step improvement). RESULTS Time to sustained ≥2-step DRSS improvement was shorter for both the IAI 2q4 and IAI 2q8 groups versus laser (both log-rank p < 0.001). Cumulative incidences of sustained ≥2-step DRSS improvement with IAI 2q4 and IAI 2q8 versus laser were 40.0% and 42.8% versus 15.5% (both p < 0.001) through week 100. Mean differences (95% CI) in BCVA gains from baseline at weeks 52 and 100 between eyes with sustained ≥2-step DRSS improvement versus sustained ≥1-step DRSS worsening were -3.0 (-8.9, 2.9) and 6.2 (0.2, 12.2) letters with laser, and 4.2 (0.8, 7.6) and 4.9 (1.3, 8.4) letters with IAI combined, respectively. Difference (95% CI) in CST reduction was significantly greater only with IAI combined at week 100 (-83.0 [-140.8, -25.3]). Correlations between BCVA and CST changes were weak. CONCLUSIONS DMO eyes treated with IAI achieved sustained ≥2-step DRSS improvement significantly earlier and more frequently versus laser. This improvement was associated with greater BCVA gains, independent of CST reductions.

Abstract
Importance Best-corrected visual acuity (BCVA) is a measure used to manage diabetic macular edema (DME), sometimes suggesting development of DME or consideration of initiating, repeating, withholding, or resuming treatment with anti-vascular endothelial growth factor. Using artificial intelligence (AI) to estimate BCVA from fundus images could help clinicians manage DME by reducing the personnel needed for refraction, the time presently required for assessing BCVA, or even the number of office visits if imaged remotely. Objective To evaluate the potential application of AI techniques for estimating BCVA from fundus photographs with and without ancillary information. Design, Setting, and Participants Deidentified color fundus images taken after dilation were used post hoc to train AI systems to perform regression from image to BCVA and to evaluate resultant estimation errors. Participants were patients enrolled in the VISTA randomized clinical trial through 148 weeks wherein the study eye was treated with aflibercept or laser. The data from study participants included macular images, clinical information, and BCVA scores by trained examiners following protocol refraction and VA measurement on Early Treatment Diabetic Retinopathy Study (ETDRS) charts. Main Outcomes Primary outcome was regression evaluated by mean absolute error (MAE); the secondary outcome included percentage of predictions within 10 letters, computed over the entire cohort as well as over subsets categorized by baseline BCVA, determined from baseline through the 148-week visit. Results Analysis included 7185 macular color fundus images of the study and fellow eyes from 459 participants. Overall, the mean (SD) age was 62.2 (9.8) years, and 250 (54.5%) were male. The baseline BCVA score for the study eyes ranged from 73 to 24 letters (approximate Snellen equivalent 20/40 to 20/320). Using ResNet50 architecture, the MAE for the testing set (n = 641 images) was 9.66 (95% CI, 9.05-10.28); 33% of the values (95% CI, 30%-37%) were within 0 to 5 letters and 28% (95% CI, 25%-32%) within 6 to 10 letters. For BCVA of 100 letters or less but more than 80 letters (20/10 to 20/25, n = 161) and 80 letters or less but more than 55 letters (20/32 to 20/80, n = 309), the MAE was 8.84 letters (95% CI, 7.88-9.81) and 7.91 letters (95% CI, 7.28-8.53), respectively. Conclusions and Relevance This investigation suggests AI can estimate BCVA directly from fundus photographs in patients with DME, without refraction or subjective visual acuity measurements, often within 1 to 2 lines on an ETDRS chart, supporting this AI concept if additional improvements in estimates can be achieved.

Abstract
Objective: To investigate the effect of oxidative stress caused by heat exposure on the blood pressure increase of treadmill rats and the intervention of antioxidants. Methods: In June 2021, Twenty-four healthy SD male rats were randomly divided into four groups: normal temperature feeding, normal temperature treadmill, high temperature treadmill and high temperature treadmill supplementation with vitamin C groups, 6 rats in each group. The rats run on the platform in normal temperature or heat exposure environment for 30 min in the morning and in the afternoon daily, 6 days per week. The daily vitamin C supplement dose of high temperature treadmill supplementation with vitamin C group was 10 mg/kg. BP recordings were done at the end of the week. The rat vascular lipofuscin (LF) was detected by ELISA, the rat serum nitric oxide (NO) was detected by nitrate reductase method, the serum malondialdehyde (MDA) was detected by thibabituric acid method, the serum glutathione peroxidase (GPx) and superoxide dismutase (SOD) were detected by chemiluminescence method, and the serum catalase (CAT) was detected by ammonium molybdate method. The total antioxidant capacity (T-AOC) of serum was measured by iron reduction/antioxidant capacity method, and the content of nuclear erythroid 2-related factor 2 (Nrf2) in vascular tissue was measured by Western blot. The intra-group mean was compared by repeated measurement analysis of variance, and the inter-group mean was compared by single-factor analysis of variance and post-event LSD-t test. Results: Compared with the previous time point, the systolic BP and diastolic BP of the high temperature treadmill group were significantly increased at 7, 14 and 21 d, and decreased at 28 d which were higher than the initial level (P<0.05), and the systolic BP and diastolic BP values at each experimental time point were significantly higher than those of normal temperature treadmill group (P<0.001). The changes of thickening of the artery wall, no smoothing of the endodermis and irregular arrangement of muscle cells in high temperature treadmill group were observed. Compared with the normal temperature treadmill group, the content of MDA in serum, and LF in vascular tissue were significantly increased, the activities of SOD, CAT, T-AOC, the content of NO in serum, and the expression of Nrf2 in vascular tissue were significantly decreased in high temperature treadmill group (P<0.05). Compared with the high temperature treadmill group, the systolic BP and diastolic BP values at 7, 14, 21 and 28 d, the content of serum MDA and LF in vascular tissue were significantly decreased, the activities of CAT and T-AOC, and the expression of Nrf2 in vascular tissue significantly increased (P<0.05), the histopathological changes of the artery wall improved in high temperature treadmill supplementation with vitamin C group. Conclusion: Heat exposure has effect on oxidative stress, which may be related to the increase of BP. Vitamin C as an anti-oxidative enhancer can prevent those negative effects, which could alleviate the pathological changes of vessel intima in heat-exposed rats. And the Nrf2 may be a regulated factor to vascular protection.

Abstract
AIM To compare the accuracy of hand-held ultrasonography (US), mammography (MG), magnetic resonance imaging (MRI), and automated breast volume scanning (ABVS) in defining residual breast cancer tumour size after neoadjuvant therapy (NAT). MATERIALS AND METHODS Patients diagnosed breast cancer and who received NAT at the Breast Center, Peking University People's Hospital, were enrolled prospectively. Imaging was performed after the last cycle of NAT. The residual tumour size, intraclass correlation coefficients (ICCs), and receiver operating characteristic (ROC) to predict pathological complete response (pCR) were analysed. RESULTS A total of 156 patients with 159 tumours were analysed. ABVS had a moderate correlation with histopathology residual tumour size (ICC = 0.666), and showed high agreement among triple-positive tumours (ICC = 0.797). With 5 mm as the threshold, the coincidence rate reached 64.7% between ABVS and pathological size, which was significantly higher than that between US, MG, MRI, and pathological size (50%, 45.1%, 41.4%; p=0.009, p=0.001, p<0.001, respectively). For ROC analysis, ABVS demonstrated a higher area under the ROC curve, but with no statistical difference, except for MG (0.855, 0.816, 0.819, and 0.788, respectively; p=0.183 for US, p=0.044 for MG, and p=0.397 for MRI, with ABVS as the reference). CONCLUSIONS The longest tumour diameter on ABVS had a moderate correlation with pathological residual invasive tumour size. ABVS was shown to have good ability to predict pCR and would appear to be a potential useful tool for the assessment after NAT for breast cancer.

Abstract
OBJECTIVES Diet is an important modifiable factor for brain health and aging. Present study aimed to explore association of dietary quality with cognitive function and poor cognition in middle-aged and older adults participating in the China Health and Nutrition Survey (CHNS). DESIGN A longitudinal study with a twenty-year follow-up. SETTING AND PARTICIPANTS Data were drawn from the CHNS 1997, 2000, 2004, 2006, 2015 and 2018. Subjects aged 55 years and more who participated in at least two waves and had completed data on socio-demographics, lifestyle, disease history, anthropometrics, dietary measure and cognitive assessment were eligible in present study. METHODS Baseline diet were assessed by 3-day 24-hour dietary recalls and used to evaluate diet quality via China Elderly Dietary Guidelines Index 2022 (CDGI 2022-E). Cognitive function was examined using part items of the Telephone Interview for Cognitive Status-modified. Three-level linear mixed effects models and three-level mixed effects logistic regression models were performed to estimate the association between diet quality and cognitive function and odds of poor cognition, respectively. RESULTS At baseline, 4173 subjects with median age of 63.7 years were recruited. Median of CDGI 2022-E total score was 44.7. Median score of global cognition was 16.0, and the proportion of people with poor cognitive function was 13.9%. Difference in global cognitive score was observed by tertiles of CDGI 2022-E (p<0.05). Significant associations of high diet quality with increment in global cognitive score [β (95%CI): 0.704 (0.394~1.015)], composite cognitive z score [0.086 (0.045~0.128)] and standardized verbal memory score [0.221 (0.122~0.320)] were observed in total subjects. Consistent associations were also found in those below 65 years at baseline. The likelihood of poor cognition in the highest tertile of CDGI 2022-E decreased by 18% (95%CI: 0.698~0.965) relative to the lowest tertile group in total population. CONCLUSIONS High diet quality may be beneficial for improving cognitive function and delaying cognitive decline in Chinese middle-aged and older population.

Abstract
OBJECTIVE To assess the relationship between baseline factors and time to diabetic macular edema (DME) resolution. DESIGN Post hoc analysis of VISTA and VIVID. PARTICIPANTS Eyes with baseline central subfield thickness (CST) of ≥ 290 μm. INTERVENTION Eyes were treated with intravitreal aflibercept injection (IAI) 2 mg (n = 558; every 4 weeks or every 8 weeks after 5 monthly doses) or laser control (n = 274). The effect of baseline factors on the time to DME resolution (CST < 290 μm) was assessed in univariable and multivariable models and further evaluated by the Kaplan-Meier method. MAIN OUTCOME MEASURES Time to and cumulative incidence of DME resolution. RESULTS Eyes treated with IAI had a 2.5-fold higher DME resolution rate, with median time of 33.0 weeks (95% confidence interval [CI], 28.1-40.0), compared with DME resolution not being achieved in 50% of eyes treated with laser control. Multivariable analysis demonstrated that a lower DME resolution rate was associated with a thicker baseline CST (hazard ratio [HR] [95% CI] per 100-μm CST increase, 0.79 [0.72-0.86]) and better baseline best-corrected visual acuity (BCVA) (HR [95% CI] per 5-letter increase, 0.87 [0.83-0.92]) with IAI. Tertiles of increasing CST (T1CST ≤ 419 μm; T2CST > 419 to ≤ 541; T3CST > 541) were associated with longer median times to DME resolution (20.1, 39.1, and 49.1 weeks, respectively; P < 0.001 for T2CST and T3CST versus T1CST) and lower cumulative incidence of events (HR, 1.0, 0.6, and 0.6, respectively; P < 0.001 for T2CST and T3CST versus T1CST) with IAI. Tertiles of increasing BCVA (T1BCVA ≤ 57 letters; T2BCVA > 57 to ≤ 66; T3BCVA >66) were associated with longer median times to DME resolution (28.4, 31.7, and 44.1 weeks, respectively; P < 0.05 for T3BCVA versus T1BCVA) and lower cumulative incidence of events (HR, 1.0, 0.9, and 0.8, respectively; P < 0.05 for T3BCVA versus T1BCVA) with IAI. No other baseline factor was associated with the time to DME resolution. CONCLUSIONS The median time to DME resolution was 33 weeks among IAI-treated eyes. A thicker baseline CST and better baseline BCVA in the IAI group were associated with a longer time to and a lower rate of DME resolution.

Abstract
Surgical treatment of tumours in the anterior mandible and surrounding tissues may result in defects which can be restored by a fibula free flap. The upper airway may change during this process. The purpose of this retrospective study was to evaluate upper airway changes after fibula free flap reconstruction. A total of 37 patients who underwent anterior mandibulectomy and fibula free flap reconstruction between 2012 and 2020 were recruited. Patients with benign and malignant tumours involving the anterior mandible were included. Spiral computed tomography was performed 1 week preoperatively, 1 week postoperatively, and at> 1 year (range 12-23 months) after surgery. Cross-sectional areas and volumes of the upper airway were measured. Data were analysed by two-way analysis of variance. The upper airway in the malignant tumour group showed an increasing trend, especially at the soft palate and tongue base levels (P < 0.01). In the benign tumour group, the upper airway showed no significant changes. The location of the minimum cross-sectional area moved downwards in both groups, and the area increased in the malignant tumour group during long-term follow-up. Upper airway obstruction is less likely to occur in the long term after surgical resection of anterior mandible malignancies and fibula free flap reconstruction.

Abstract
OBJECTIVES This study aimed to examine the impact of deviant peer affiliation on migrant children's school adaptation in China and explore the mediating role of mental health in the relationship between deviant peer affiliation and school adaptation among migrant children. STUDY DESIGN This was a cross-sectional study based on secondary data. METHODS This study was based on the nationally representative China Education Panel Survey. Multiple linear regression models were used to quantify the relationship between deviant peer affiliation and school adaptation among 1,012 migrant children aged 12-17 years. Bootstrap test was used to evaluate the mediating effect of children's mental health. RESULTS Deviant peer affiliation showed a significant negative impact on the school adaptation of migrant children (β = -0.41, 95% confidence interval = -0.56 to -0.26). The relationship between deviant peer affiliation and school adaptation was partially mediated by children's mental health, resulting in an indirect effect of deviant peer affiliation on their school adaptation through their mental health (β = -0.05, 95% confidence interval = -0.09 to -0.03). The mediating role of mental health could explain 11.4% of the relationship between deviant peer affiliation and school adaptation. CONCLUSIONS Among migrant children, deviant peer affiliation showed unique effects on their school adaptation. Taking care of their mental health might help improve their school adaptation.

Abstract
BACKGROUND Tumor growth rate (TGR), denoted as percentage change in tumor size per month, is a well-established indicator of tumor growth kinetics. The predictive value of early on-treatment TGR (EOT-TGR) for immunotherapy remains unclear. We sought to establish and validate the association of EOT-TGR with treatment outcomes in patients with advanced non-small-cell lung cancer (aNSCLC) undergoing anti-PD-1/PD-L1 (programmed cell death protein 1/programmed death-ligand 1) therapy. PATIENTS AND METHODS This bicenter retrospective cohort study included a training cohort, a contemporaneously treated internal validation cohort, and an external validation cohort. Computed tomography images were retrieved to calculate EOT-TGR, denoted as tumor burden change per month during a period between baseline and the first imaging evaluation after immunotherapy. Kaplan-Meier methodology and Cox regression analysis were conducted for survival analyses. RESULTS In the pooled cohort (n = 172), 125 patients (72.7%) were males; median age at diagnosis was 58 (range 28-79) years. Based on the training cohort, we determined the optimal cut-off value for EOT-TGR as 10.4%/month. Higher EOT-TGR was significantly associated with inferior overall survival [OS; hazard ratio (HR) 2.93, 95% confidence interval (CI) 1.47-5.83; P = 0.002], worse progression-free survival (PFS; HR 2.44, 95% CI 1.46-4.08; P = 0.001), and lower objective response rate (3.3% versus 20.9%; P = 0.040) and durable clinical benefit rate (6.7% versus 41.9%; P = 0.001). Results were reproducible in the two validation cohorts for OS and PFS. Among 43 patients who had a best response of progressive disease in the training cohort, those with high EOT-TGR had worse OS (HR 2.64; P = 0.041) and were more likely to progress due to target lesions at the first tumor evaluation (85.2% versus 0.0%; P <0.001). CONCLUSIONS Higher EOT-TGR was associated with inferior OS and immunotherapeutic response in patients with aNSCLC undergoing anti-PD-1/PD-L1 therapy. This easy-to-calculate radiologic biomarker may help evaluate the abilities of immunotherapy to prolong survival and assist in tailoring patients' management.

Abstract
Objective: To systematically evaluate the efficacy and safety of rock salt aerosol in the treatment of respiratory tract diseases. Methods: In June 2021, the clinical randomized controlled trial literatures of rock salt aerosol therapy for respiratory tract diseases were searched from CNKI, Wanfang, VIP, Cochrane Library, PubMed database and EMBASE database. Cochrane risk bias evaluation tool was used to evaluate risk bias, Revman 5.4 and Stata16 were used to conduct meta-analysis, TSA 0.9 was used to conduct sequential analysis of trials, and gradepro was used to evaluate evidence quality. Results: A total of 21 literatures were included. According to whether the subjects received rock salt aerosol therapy, they were divided into the experimental group (1125 people) and the control group (973 people) . Compared with the control group, the total clinical effective rate (RR=1.22, 95%CI: 1.15~1.29, P<0.001) , forced expiratory volume in one second (FEV(1)) (WMD=0.20, 95%CI: 0.09~0.31, P<0.001) , percentage of FEV(1) in the predicted value (FEV(1)%) (WMD=5.06, 95%CI: 3.47~6.65, P<0.001) , forced vital capacity (FVC) (WMD=0.22, 95% CI: 0.16~0.27, P<0.001) , maximum expiratory flow (PEF) (WMD=21.312, 95%CI: 9.189~33.435, P=0.004) of experimental group were higher. TSA test shows that the difference conclusions of total effective rate, FEV(1), FEV(1)%, FVC and PEF were reliable, but the conclusion of FEV(1)% needs to be treated with caution; Three literatures reported the adverse reactions in the experimental group; GRADE evidence quality evaluation showed 3 very low-quality evidences and 2 low-quality evidences. Conclusion: Rock salt aerosol therapy combined with conventional therapy has a certain effect on the treatment of respiratory tract diseases, which needs to be further confirmed by high-quality evidence.

Abstract
Purpose: This work aimed to assess the incidence of proliferative diabetic retinopathy (PDR) events and improvement to mild non-PDR (NPDR) or better after intravitreal aflibercept injection (IAI) or laser treatment (control) in diabetic macular edema (DME). Methods: PDR events in the VISTA (NCT01363440) and VIVID (NCT01331681) phase 3 clinical trials were evaluated in a combined IAI-treated group (IAI 2 mg every 4 weeks or 2 mg every 8 weeks after 5 initial monthly doses; n = 475) and a macular laser control group (n = 235) through week 100 in eyes without PDR at baseline (Diabetic Retinopathy Severity Scale [DRSS] score ≤ 53). Improvement in the DRSS score to 35 or better was evaluated in those with a baseline DRSS score of 43 or greater. Results: A lower proportion of eyes in the IAI group than in the laser group developed a PDR event through week 100 (4.4% vs 11.1%; adjusted difference, −6.7%; 97.5% CI, −11.7 to −1.6; nominal P = .0008). All PDR events occurred in eyes with a baseline DRSS score of 43, 47, or 53 and not in those with a score of 35 or less. A greater proportion of eyes in the IAI group than in the control group achieved a DRSS score of 35 or less (20.0% vs 3.8%; nominal P < .0001). Conclusions: Fewer eyes with NPDR and DME treated with IAI than eyes treated with a laser had a PDR event. More eyes treated with IAI improved to mild NPDR or better (DRSS score ≤ 35) through 100 weeks.

Abstract
Purpose: To assess the correlation between the change in central subfield thickness (CST) and change in best-corrected visual acuity (BCVA) in eyes with diabetic macular edema (DME) treated with fixed-dosing intravitreal aflibercept injection (IAI). Methods: This post hoc analysis of the VISTA and VIVID randomized controlled clinical trials, in which 862 eyes with central-involved DME were randomly assigned to IAI 2 mg every 4 weeks (2q4; 290 eyes), IAI 2 mg every 8 weeks after 5 initial monthly doses (2q8; 286 eyes), or macular laser (286 eyes) and followed through 100 weeks. Correlations between the change in CST and change in BCVA from baseline to weeks 12, 52, and 100 were assessed using the Pearson correlation. Results: The respective correlations ( r [95% CI]) at weeks 12, 52, and 100 were −0.39 (−0.49 to −0.29), −0.27 (−0.38 to −0.15), and −0.30 (−0.41 to −0.17) in the 2q4 arm and −0.28 (−0.39 to −0.17), −0.29 (−0.41 to −0.17), and −0.33 (−0.44 to −0.20) in the 2q8 arm. Linear regression analysis of the correlation at week 100, adjusted for relevant baseline factors, showed CST changes accounted for 17% of the variance in BCVA changes; every 100-µm decrease in CST was associated with a 1.2-letter increase in BCVA ( P = .001). Conclusions: Correlations between the change in CST and change in BCVA after 2q4 or 2q8 fixed-dosing IAI for DME were modest. Although a change in CST might be important in determining the need for antivascular endothelial growth factor for DME at follow-up, it was not a good surrogate for VA outcomes.

Abstract
Purpose
Assess correlation between change in central subfield thickness (CST) and change in best-corrected visual acuity (BCVA) in eyes with macular edema due to retinal vein occlusion (RVO) that received intravitreal aflibercept injections (IAI). Methods Post hoc analysis of COPERNICUS and GALILEO trials for CRVO and VIBRANT trial for BRVO with relationships determined using Pearson correlation coefficient. Results In COPERNICUS, correlations (r) between change in CST and change in BCVA from baseline at weeks 12, 24, 52, and 100 were −0.36 (95% CI: −0.52, −0.18; P < 0.001), −0.38 (95% CI: −0.53, −0.20; P < 0.001), −0.44 (95% CI: −0.58, −0.27; P < 0.001), and −0.41 (95% CI: −0.56, −0.23; P < 0.001), respectively. CST changes accounted for only 21% of the variance in BCVA changes; every 100-µm decrease in CST was associated with a 2.1-letter increase in BCVA (P = 0.003). Similar findings were noted for GALILEO (r, −0.45 to −0.23) and VIBRANT (r, −0.36 to −0.32) trials. Conclusion In eyes treated with IAI for macular edema due to RVO, correlation between change in CST and change in BCVA was weak to moderate. While change in CST may be helpful in determining the need for anti-VEGF therapy, these findings do not support using changes in CST as a surrogate for changes in visual acuity outcomes. ![]() Supplementary Information The online version contains supplementary material available at 10.1007/s00417-022-05697-4.

Abstract
Objective: To identify prognostic factors for revitrectomy in patients who underwent pars plana vitrectomy (PPV) for complications with proliferative diabetic retinopathy (PDR). Methods: This study was a retrospective case-control study. Clinical data of PDR patients (290 eyes) at Peking University People's Hospital from December 2019 to December 2020 were retrospectively collected.According to the number of operations, patients were divided into two groups: single PPV group (227 eyes) and revitrectomy PPV group (63 eyes). Follow-up will be conducted up to 6 months postoperatively. The BCVA was compared before and after PPV between the two groups, and postoperative complications of revitrectomy PPV group were analyzed. Quantitative data are presented as medians [M (Q1, Q3)]. Results: The age of single PPV group patients was 55.0 (47.0, 63.0), and the age of revitrectomy PPV group patients was 49.0 (38.0, 57.0). This difference was statistically significant (P=0.027). The LogMAR visual acuity of two groups were 1.7 (1.0, 2.4) and 2.1 (1.4, 2.4) (P=0.026) preoperative; the visual acuity of single PPV group was 0.75 (0.43, 1.00) (P<0.001), and revitrectomy PPV group was 0.95 (0.60, 1.65) (P<0.001) at 6 months postoperative. The visual acuity improvement of single PPV group was better than revitrectomy PPV group (P=0.021). Age (P=0.043, OR=0.97, 95%CI: 0.95-1.00), preoperative BCVA (P=0.024, OR=1.82, 95%CI: 1.08-3.05), tractional retinal detachment (TRD) (P=0.033, OR=2.16, 95%CI:1.06-4.37), silicone oil tamponade (P=0.028, OR=0.48, 95%CI: 0.25-0.92) were prognostic factors of revitrectomy. Conclusion: Young age, low preoperative BCVA, TRD, and silicon oil tamponade were the potential prognostic factors of revitrectomy for PDR patients.

Abstract
Abstract
For larger containments and higher operation parameters, characteristics of the outside cooling of the PCCS are very important for the analysis on the containment integrity. A preliminary analysis was made and a four-step experimental method was used to numerically analyze the falling water film evaporation for the advanced passive containment. Then, the water flow stability along the outside wall of the containment was studied. The results fit well with those correlations without airflow when the air velocity is less than 5.0 m/s. However, when the air velocity is larger than 5.0 m/s, the influence of the air velocity on the water film will appear and the mean water film thickness will be thicker. Based on the prototype operation parameters, experimental studies were carried and the results were compared with the Dittus-Boelter correlation within the operation ranges. A modification factor was proposed for the conservative application of this correlation for nuclear safety analysis.

Abstract
Objective: To explore the clinical characteristics, treatment methods and outcomes of extramedullary plasmacytoma of the head and neck. Methods: A retrospective analysis was conducted on 10 cases with extramedullary plasmacytoma of the head and neck who were admitted to Henan Tumor Hospital from January 2005 to January 2020. Among the 10 patients, 6 were male and 4 were female. The average age at diagnosis was 56.3 years old (34-74 years old). Among them, 3 cases were located in the nasal cavity, 2 cases in the nasopharynx, 1 case in the sinuses, 2 cases in the larynx, 1 case in the oropharynx, and 1 case in the cervical lymph nodes. Treatments were administered according to tumor size and resection extent. Complete surgical excision (negative margins) was preferred, followed by adjuvant radiotherapy or radiotherapy alone. The clinical characteristics, diagnosis, treatment and prognosis of EMP were analyzed. Results: The patients' symptoms were not specific, frequently with local obstruction symptom and localized masses. All patients were confirmed pathologically as suffering from monoclonal plasmacytoma, with negative bone marrow biopsy and negative skeletal survey. Five patients received surgery, 3 received radiotherapy, and 2 received surgery with additional radiation. The follow-up time was 16-125 months, with a median of 92 months. Two patients developed into multiple myeloma. One patient who received radiotherapy after surgery relapsed after 7 years of follow-up and again received surgical treatment, with no evidence of second recurrence. The remaining patients had no recurrence or progression. Conclusion: Extramedullary plasmacytoma of the head and neck has a good prognosis. Surgical treatment can be considered for completely resectable lesions.

Abstract
Abstract
Many older people admitted to hospital are malnourished/at risk of malnourishment (30%), have swallowing problems (55%), are frail (25%), have sarcopenia (50%) or a combination of these. On admission to hospital frail older people are at significant risk of worsening nutritional status and prolonged hospital stay. Nutritional status should be identified, documented, food intake monitored and where appropriate they should be referred to the dietitian.
The question remains, do staff recognise that frail older people may not eat their food increasing their risk of poor nutrition and outcome.
Methods
Older people admitted to a ‘Frailty’ Ward were directly observed during lunchtime by WD. The Minimal Eating Observation Form –Version II (MEOF-II) was used to document how much they ate. Frailty status (CFS), presence of Sarcopenia (Sarc-F) and whether a referral to dietetics or speech and language therapy (SLT) was completed.
Results
39 patients were observed. Mean age was 82.38 years; median CFS 6 (3–8); median Sarc-F 4(0–9). Median MEOF II was 0 (0–5). Two patients were referred to dietetics and 4 to SLT. 7/40 (17,5%) were at high risk for undernutrition, a further 8/40(20%) were at moderate risk. 82% were severely frail, the remaining were mildly frail. 94% (16/17) exhibited sarcopenia. There was significant correlation between MEOF II and CFS (r = 0.4887, p = 0.00162); MEOFII and Sarc-F (r = 0.4395, p = 0.00512). There was correlation between CFS and Sarc-F (r = 0.80296, p < 0.00001). Only one (6%) was referred to the dietitian.
Conclusion
Frail older adults are often undernourished on admission to hospital. Nutritional intake is often poor with acute illness. Screening, observation and monitoring of nutritional intake should highlight concerns and needs for intervention. These study high lights that a significant number of older people are frail, fail to complete meals, are at significant risk of under nutrition, yet proactive intervention does not occur.

Abstract
Background:Tissue-resident memory T cells (TRM), are a recently identified T cells population featuring tissue localization and expression of markers of tissue homing, CD69 and CD103. Recently, the expansion of CD8+ TRMs and their involvement in the sialadenitis was described in a murine model of SS. However, CD4+ and CD8+ TRM’s functional relevance in pSS is still not fully understood, and the TRM therapeutic targeting unexplored.Objectives:The study aimed to address the role of CD4+ and CD8+ TRMs in the pathogenesis of pSS and to explore the therapeutic targeting of the tissue residency marker of TRM CD103.Methods:An animal model of experimental (ESS) obtained by immunization of female C57BL/6 mice (n=10) with salivary glands (SG) protein extract and Freund’s complete adjuvant used to investigate the dynamic of infiltration of SG by CD4+ and CD8+ TRMs, their frequency, and the impact of CD103 blockade. For the therapeutic intervention, at 10-weeks post-immunization, the salivary gland was cannulated via Wharton’s duct, and an anti-CD103 neutralizing antibody or vehicle-injected. The mice’s saliva flow rate was assessed, and SGs were analyzed by Flow-cytometry and immunohistochemistry (IHC).The frequency and localization of TRMs was analyzed in minor SG of sicca syndrome (nSS) and pSS patients (n=39) by flow cytometry and IHC. The expression of genes involved in the tissue retention of TRMs was assessed in SG by RT-PCR.Results:Upon the ESS progression, a significant progressive increase in CD45+CD103+ cells frequency was observed from 5wk to 20wk post-immunization (p<0.001), where the CD8+ were the most abundant, followed by CD4+. Consistently, CD103+CD8+ T cells were detected within the lymphocytic infiltration of SG from ESS mice. Sorted purified SG CD10+CD3+CD8+ T cells showed higher Granzyme B, TNF-alpha expression compared to CD103-CD3+CD8+ at both mRNA and protein levels. Notably, ESS mice treated with anti-CD103 showed improvement in salivary function (p<0.05) and reduced lymphocytic infiltrations measured as focus score (FS) (p<0.01) and area-fraction (p<0.01). Consistently, anti-CD103 treatment consistently reduced CD103+ cells and IFN-gamma+, Granzyme B+, and TNFa+ CD8+ cells. We next performed phenotypic analysis of CD45+CD103+ immune cells in the SG of pSS patients observing an increase in both with CD8+CD103+CD69+ and CD4+CD103+CD69+ (p<0.05). Finally, IHC showed that the expansion of TRMs in pSS salivary glands was accompanied by a down-regulation of E-cadherin glandular expression and their migration outside the epithelium in the context of inflammatory infiltrates. SG of patients with pSS showed a significant up-regulation of BLIMP1, KFL-2, and S1PR1 and down-regulation of ITGB2. CXCL9 and CXCL10, and IL-15 involved in the tissue recruitment and long-term survival of TRMs were significantly modulated in pSS salivary glands.Conclusion:TRM are expanded and activated in the SG of pSS and ESS, participating in the organization of tissue inflammation. Although the mechanisms behind this expansion are still not fully understood, CD103 could be a valuable novel therapeutic target to prevent lymphocytic infiltrations and glandular destruction in Sjogren syndrome.Disclosure of Interests:None declared

Abstract
OBJECTIVE To investigate the protective role of ulinastatin (UTI) on myocardial ischemia-reperfusion (I/R) injury in rats via endoplasmic reticulum stress (ERS)-induced apoptosis pathway. MATERIALS AND METHODS A total of 60 rats were randomly divided into normal group (n=20), myocardial I/R model group (model group, n=20), and myocardial I/R model+UTI treatment group (treatment group, n=20). The myocardial function indicators [creatinine (Scr) and creatine kinase (CK)] were detected. Enzyme-linked immunosorbent assay (ELISA) was performed to measure serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and matrix metalloproteinase-9 (MMP-9). Meanwhile, the contents of reactive oxygen species (ROS), superoxide dismutase (SOD), and malondialdehyde (MDA) in rat left ventricular tissues were determined by ELISA as well. The cardiac function indexes were determined via magnetic resonance imaging (MRI) and echocardiography (ECG). Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labeling (TUNEL) staining assay was carried out to detect the apoptosis of myocardial tissues. Additionally, the expression levels of endoplasmic reticulum stress and apoptosis genes were measured through quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) assay and Western blotting analysis, respectively. RESULTS Serum levels of alanine aminotransferase (ALT), CK, and Scr in model group were significantly higher than those in normal group (p<0.05). Besides, rats in model group had significantly lowered SOD, ejection fraction (EF, %), and fractional shortening (FS, %) than those in normal group (p<0.05). In addition, remarkably increased contents of TNF-α, IL-6, MMP-9, MDA, and ROS, as well as higher left ventricular end-diastolic diameter (LVEDd) and left ventricular end-systolic diameter (LVESd) were observed in model group in comparison with normal group (p<0.05). TUNEL staining results revealed that there were more apoptotic cells in model group than that in the other two groups (p<0.05). Expression levels of cysteine aspartic acid-specific protease 12 (Caspase-12) and glucose-regulated protein 78 (GRP78) were evidently higher in model group than those in normal group (p<0.05), while the expression level of B-cell lymphoma 2 (Bcl-2) was clearly lower in model group than that in normal group (p<0.05). UTI treatment partially reversed the above expression changes (p<0.05). CONCLUSIONS UTI has a protective effect against myocardial I/R injury in rats by repressing the occurrence of ERS-induced apoptosis.

Abstract
OBJECTIVE To study the effect of RBMS3 on nucleus pulposus cells and its effect on the Wnt/β-catenin signaling pathway. PATIENTS AND METHODS We measured the expression of RBMS3 in human nucleus pulposus tissues with different degrees of degeneration. Recombinant human IL-1β is used to stimulate the degeneration of human nucleus pulposus cells. We used Wnt/β-catenin signaling pathway inhibitors and cell transfection to study the effect of RBMS3 on nucleus pulposus cells and its mechanism. RESULTS RBMS3 was less expressed in the nucleus pulposus tissue of people with higher degeneration degree. IL-1β reduced the expression of RBMS3 in nucleus pulposus cells. Overexpression of RBMS3 can promote the proliferation of nucleus pulposus cells and reduce the apoptosis and inflammation of cells. In addition, RBMS3 can reduce the expression of β-catenin and c-myc in nucleus pulposus cells, and inhibit the activity of the Wnt/β-catenin signaling pathway. CONCLUSIONS RBMS3 inhibits the Wnt/β-catenin signaling pathway, improves the proliferation ability of nucleus pulposus cells, inhibits their apoptosis and inflammation, and thus delays the degeneration of the intervertebral disc.

Abstract
Objective: To compare the long-term clinical effect and imaging results of Bryan artificial cervical disc replacement (ACDR) and anterior cervical discectomy and fusion (ACDF) and to explore whether ACDR can reduce the occurrence of postoperative adjacent segment degeneration (ASD) in the treatment of degenerative cervical spondylosis. Methods: It was a retrospective study. Total of 60 patients with degenerative cervical spondylosis, who had received operations by Bryan ACDR (n=27) and ACDF (n=33) in the Third Hospital of Hebei Medical University between January 2005 and December 2009 were enrolled in this study. The Japanese Orthopedic Association (JOA) scores, neck disability index (NDI), visual analogue scale (VAS), Odom's scale, cervical range of motion (ROM), surgical segment ROM, heterotopic ossification (HO) and ASD were used to evaluate the clinical and radiologic results. The indices abovementioned were compared between the two groups. Results: The VAS, NDI and JOA scores at each follow-up node in both ACDR and ACDF group were all significantly improved when compared with those before operation (all P<0.05), but there was no significant differences between the two groups (all P>0.05). Of all, 88.9%(24/27) of patients in ACDR group and 84.8%(28/33) of patients in ACDF group achieved excellent or good results, however, there was no significant difference in Odom's scale between the two groups (P>0.05). At the last follow-up, the cervical ROM in ACDR group was 43.2°±8.8°, which was slightly lower than that before operation (45.7°±10.4°), the difference was not statistically significant (t=0.954, P=0.345); the surgical segment ROM in ACDR group was 5.9°±3.6°, which was significantly reduced when compared with that before operation (8.8°±3.4°, t=3.043, P<0.01). However at the last follow-up, the cervical ROM in ACDF group was 36.4°±8.4°, which was significantly reduced when compared with that before operation (43.9°±11.1°), the difference was statistically significant (t=3.095, P<0.01). Although, there was no significant difference in the cervical ROM between the two groups before operation (t=0.643, P=0.523), and the difference was statistically significant at the last follow-up (t=3.054, P<0.01). At the last follow-up, the incidence of HO in ACDR group was 92.6%, and the high-grade HO was 37.0%. The incidence of ASD in ACDR group was 39.5%, which was much lower than that in ACDF group (61.1%, χ(2)=4.462, P=0.035). Conclusion: At minimum follow-up of 10 years, Bryan ACDR achieves a satisfactory clinical effect consistent with ACDF. In terms of advantages, ACDR could maintain the ROM of cervical and retain the ROM of the surgical segment, which reduces the occurrence of ASD by preserving motion.

Abstract
OBJECTIVES Tuberculous pleurisy (TP) diagnosis remains difficult, with the sensitivity of Xpert MTB/RIF (Xpert) and mycobacterial culture (culture) only about 30-50%. We aimed to assess the diagnostic performance of a cell-free Mycobacterium tuberculosis DNA test (cf-TB) in pleural effusion for TP. METHODS Adults (≥18 years) with suspected TP presenting with pleural effusion were consecutively recruited, and pleural effusion specimens were prospectively collected in Beijing Chest Hospital, Beijing, China. After centrifuging pleural effusion, sediments were used for culture, Xpert and T-SPOT.TB assay, whereas supernatants were used for cf-TB and adenosine deaminase assay. The diagnostic performance was assessed against a composite reference standard. RESULTS From June 2015 to December 2018, we prospectively evaluated 286 adults with suspected TP. One hundred twenty-two participants were classified as definite TP based on the prespecified composite reference standard. The cf-TB produced a sensitivity of 79.5% (97/122, 95% confidence interval (CI) 72.4- 86.7) for definite TP, which was superior to Xpert (38.5% (29.9-47.2); 47/122; p < 0.001) and culture (27.1% (19.2-34.9); 33/122; p < 0.001). With pleural effusion Xpert and/or culture as the reference standard, cf-TB showed 96.6% (57/59, 95% CI 92.0-100.0) sensitivity, which was also significantly higher than Xpert (79.7%, 95% CI 69.4-89.9; 47/59; p 0.004) and culture (55.9%, 95% CI: 43.3-68.6; 33/59; p < 0.001). CONCLUSIONS The cf-TB clearly showed improved sensitivity compared with Xpert and culture. We recommend cf-TB as the first-line test for TP diagnosis.

Abstract
Objective: To evaluate the using value of FibroTouch and six serological models in detecting the degree of liver fibrosis in patients with chronic hepatitis B, in an attempt to provide reference for accurate diagnosis. Methods: Two hundred and fifty-eight cases with chronic hepatitis B admitted to Xixi Hospital of Hangzhou from September 1, 2015 to September 1, 2017 were selected. All patients underwent liver histopathological examination and FibroTouch measurement to determine liver stiffness (LSM). Serum biochemical parameters were detected and the scoring values of six serological models were calculated. SAS 9.4 statistical software was used for statistical analysis, and the correlation between FibroTouch and the six serological models was analyzed by Spearman correlation. The diagnostic value of FibroTouch and six serological models was analyzed by receiver operating characteristic curve (ROC) based on liver histopathological findings. Results: The median LSM of 258 cases with chronic hepatitis B was 9.4 (6.5-13.8) kPa. In the six serological models, the median value of aspartate transaminase to platelet ratio index (APRI), FIB-4 index, S-index, Forn's index, PRPindex, and FIB-5 were 0.42 (0.28-0.62), 1.27 (0.78-2.03), 0.11 (0.07-0.20), 6.95 (5.89-8.51), 0.000 8 (0.000 6-0.000 9),and 38.59 (36.28-40.97). FibroTouch had positive correlation with APRI, FIB-4, S-index, Forn's index, PRP, fibrosis stage (r= 0.73,P< 0.001) and inflammation grade, and had negative correlation with FIB-5, and both had statistical significance. The area under curve (AUC) of FT-LSM at S≥2, S≥3, S = 4 were 0.89, 0.90 and 0.85, respectively, which was significantly higher than serological models (P< 0.001). The AUC of S-index model at S≥2, S≥3, S = 4 were higher than other five serological models. Conclusion: The diagnostic performance of FibroTouch is significantly better than serological model. S-index model has the best diagnostic performance in the six serological models, and the combination of S-index and FT-LSM may better diagnose the grading of liver fibrosis, and thus can be applied and promoted in clinic.

Abstract
The aim of this paper was to introduce a simple and effective method to aid in isolation and stabilization of Dupuytren cords for collagenase injection. Tongue depressors were used to isolate and stabilize the cord during the injection procedure. The area to be injected was sterilely prepared. An assistant was then directed to place a tongue depressor on both sides of the cord. A total of 35 patients with Dupuytren disease were treated. Follow-up lasted two years. Post-operative Disabilities of the Arm, Shoulder and Hand (DASH) scores was 4±2. Health-related quality of life measured with the EQ-5D index was 0.89±0.4. Recurrence rates of metacarpophalangeal joint and proximal interphalangeal joint were 11% and 14% respectively, using a flexion contracture of 20° to define recurrence. Collagenase treatment using a modified injection method with the aid of tongue depressors are a safe, effective way to treat Dupuytren contractures of the fingers. The technique can isolate the cord, which improves visualization of the cord. It may allow improved accuracy with needle placement and helps to decrease the complications and recurrence.

Abstract
OBJECTIVE To find variations in Chinese obesogenic environmental priorities from 2000 to 2011, predict spatiotemporal distribution of obesity prevalence aged 7-17 years in 31 provinces, and provide foundations for policy-makers to reduce obesity in children and adolescents. METHODS Based on data examination of provincial obesity prevalence aged 7-17 years from three rounds of China Health and Nutrition Surveys (in 9 [2000], 9 [2006], and 12 [2011] provinces) and corresponding years' environments in 31 provinces from China Statistical Yearbooks and other sources, 12 predictors were selected. We used 30 surveyed provinces in three rounds as training samples to fit three analytic models with partial least-square regressions and prioritized predictors by variable importance projection to find variations. And fitted a spatiotemporal prediction model with Bayesian analysis to infer in space-time. RESULTS Variations of obesogenic environmental priorities were found at different times. A Bayesian spatiotemporal prediction model with deviance information criterion of 155.60 and statistically significant (P < 0.05) parameter estimates of intercept (-717.0400, 95% confidence intervals [CI]: -1186.0300, -248.0480), year (0.3584, CI: 0.1245, 0.5924), square of food industry level (0.0003, CI: 0.0002, 0.0004), and log (healthcare) (5.3742, CI: 2.5138, 8.2347) was optimized. Totally inferred average obesity prevalence among children and adolescents were 2.23%, 5.11%, 10.77%, 12.20%, 13.99%, and 17.58% in 31 provinces in China in 2000, 2006, 2011, 2015, 2020, and 2030, respectively. Obesity in north and east of China clusters on predicted maps. CONCLUSIONS Obesity prevalence in children and adolescents in China is rapidly increasing, growing at 0.3584% annually from 2000 to 2011. From longitudinal observation, prevalence was significantly influenced by food industry ("Amplifier") and healthcare service ("Balancer"). Targeted interventions in north and east of China are pressing. Further researches on the mechanisms underlying the influence of food industry, healthcare service, and so on in children and adolescents are needed.

Abstract
BACKGROUND Little is known about the sociodemographic and clinical characteristics of adverse drug events (ADEs) in patients with neurodevelopmental disorders (NDD). OBJECTIVE The objective of this study was to describe and compare the demographic details of people with and without NDD hospitalised due to ADEs. METHODS The all-inclusive New South Wales Admitted Patient Data Collection from 2001 to 2014 was employed to identify ADE-related hospitalisations in patients with NDD using the International Classification of Diseases 10th revision Australian modification codes. We derived case sets specific to different clinical groups and patient characteristics and compared proportional differences between patients with and without intellectual disability using chi squared tests. RESULTS A total of 2173 patients with NDD were admitted for acute care of ADEs, accounting for 0.7% of all ADE-related hospitalisations. Hospitalised ADEs among patients with NDD increased by twofold over the 14-year study period. Psychotropic medications and opioid analgesic medications were leading causes of ADE-related hospitalisations in patients with NDD. Compared with their counterparts, patients with NDD were younger, experienced more socio-economic disadvantage and less private insurance coverage, suffered with less severe but different co-morbid clinical conditions and incurred more challenges in the acute hospital care setting. CONCLUSION Although the pattern of ADE-related hospitalisations in patients with NDD differed from that in patients without NDD, there is a lack of targeted healthcare programmes to meet their special needs. This study suggests the need for countermeasures in primary healthcare settings to reduce the burden of ADEs in this vulnerable group.

Abstract
PURPOSE To evaluate changes in retinal perfusion status with intravitreal aflibercept injection (IAI) and laser treatment in the phase 3 VISTA study of patients with diabetic macular edema (DME). DESIGN Post hoc analysis of a double-masked, randomized, active-controlled, phase 3 trial. PARTICIPANTS Patients with center-involved DME in the study eye. METHODS VISTA randomized 466 patients to laser, IAI 2 mg every 4 weeks (2q4), or IAI 2 mg every 8 weeks after 5 monthly doses (2q8). One eye per patient was enrolled in the study. Retinal perfusion status was evaluated by fluorescein angiography based on the presence or absence of retinal nonperfusion (RNP) in quadrants intersecting at the optic nerve head by a masked independent reading center at weeks 24, 52, 72, and 100. Visual and anatomic outcomes were evaluated at all visits. In patients who received rescue treatment, data were censored from the time rescue treatment was given. MAIN OUTCOME MEASURES Change in perfusion status from baseline through week 100. RESULTS At week 100, the proportion of eyes with improvement in retinal perfusion (defined as a reduction from baseline in the total number of quadrants in which RNP is present) in the laser control, 2q4, and 2q8 groups was 14.6%, 44.7%, and 40.0%, respectively. The proportion of eyes that experienced worsening in retinal perfusion (defined as an increase from baseline in the total number of quadrants in which RNP is present) at week 100 in the laser control, 2q4, and 2q8 groups was 25.0%, 9.0%, and 8.6%, respectively. CONCLUSION Post hoc analysis of the phase 3 VISTA study in patients with DME provides evidence that regular IAI dosing not only can slow worsening of retinal perfusion associated with diabetic retinopathy but also may be able to improve retinal perfusion in some cases by decreasing zones of RNP.

Abstract
This study investigated the surgical outcomes and accuracy of computer-assisted osteotomy guides and pre-bent titanium plates in the treatment of patients with facial asymmetry. Thirteen patients with facial asymmetry undergoing bimaxillary orthognathic surgery were included. Virtual simulation of Le Fort I osteotomy, sagittal split ramus osteotomy, and genioplasty, if needed, was conducted on the preoperative three-dimensional model. Computer-assisted osteotomy guides and pre-bent titanium plates were produced and used in the actual operation. The postoperative outcome was assessed for facial symmetry and surgical accuracy. All patients were followed up for at least 18 months and their level of satisfaction was investigated. Use of the computer-assisted osteotomy guides and pre-bent titanium plates was successful in all patients. Maxillary canting, mandibular ramus inclination, and mandibular length were corrected on both sides postoperatively. Superimposition of the surgical simulation and postoperative images demonstrated favourable accuracy. Quantitative analysis revealed a mean linear difference of <0.60mm in the maxilla and 1.57mm in the mandible. All patients were satisfied with the surgical outcome; there were no complications or cases of relapse during follow-up. The application of computer-assisted osteotomy guides and pre-bent titanium plates achieved favourable outcomes and accuracy, improving planning for the correction of facial asymmetry.

Abstract
We aimed to describe the treatment of comminuted fractures of the base of the thumb metacarpal using a cemented bone-K-wire frame. Between March 2010 and January 2016, 41 fractures of the base of the thumb were treated using a cemented bone-K-wire frame. The mean age of the patients was 34 years. The patients' history included a fall onto the hand in 7 cases, direct trauma in 31 cases, and polytrauma with an unclear mechanism of injury in 3 cases. At the final follow-up, hand grip and pinch strength were measured using a dynamometer. All measurements were compared with those of the opposite hand. The patients were assessed functionally using the Smith and Cooney score.All K-wires were left in place until the bone healed. Bone healing was achieved in all thumbs in an average of 5.2 weeks. Follow-up averaged 27 months. The mean hand pinch and grip strength was 8.7 kg ± 2.4 kg and 38.4 kg ± 5.9 kg, respectively. The mean measurements on the opposite side were 9.2 kg ± 2.5 kg and 40.2 kg ± 6.6 kg, respectively. Based on the Smith and Cooney score, we obtained an average score of 87 ± 9.3, with 25 excellent, 9 good, and 2 fair results. The cemented bone-K-wire frame is an external fixator alternative that can be used for treating comminuted intra-articular fractures of the base of the thumb metacarpal. The system is cheap, easy to apply, and provides rigid fixation, resulting in good functional recovery.
