992 and 0.991) and Miniaci's methods (0.988 and 0.987). When planning for an opening wedge osteotomy (OW) and a closing wedge osteotomy (CW), using the Miniaci method and comparing the correction angle with the angle obtained by the Dugdale method, the Miniaci OW and CW angles were larger by a factor of 1.07 (95% CI 1.06-1.08) and 1.10 (95% CI 1.09-1.11). Postoperatively, a mean undercorrection of 2.9° (SD = 2.3) was found. Predicting the correction with use of the calculated Miniaci angles resulted in an undercorrection of 2.5°, indicating that use of the Dugdale method accounted for 14% of the undercorrection.

It is more likely to underestimate the correction angle when using the Dugdale method compared to the Miniaci method. This could lead to poorer correction accuracy. As the inter-rater reliability is excellent for both methods, choosing to use the Dugdale method on basis of simplicity is not justified.

One of the preventive strategies for periprosthetic joint infection (PJI) is the use of antibiotic-loaded bone cement (ALBC) in primary total joint arthroplasty (TJA). Even though it is widely used, there are concerns about the development of antibacterial resistance. The aim of the study was to investigate whether using ALBC in primary TJA increases the antibiotic-resistant PJI. The hypothesis was that the regular use of ALBC does not increase the rate of resistant PJI.

Patients with confirmed PJI who had revision surgery from year 2010 to 2019 were included in this international multicenter study. The ALBC group was compared to the non-ALBC TJA group from the same time period. Tanespimycin mw Medical records were used to collect clinical (age, gender, body mass index, comorbidities), TJA-related (type of operation, implant type and survival) and PJI-related (cultured microorganism, antibiogram) data. Resistance to gentamicin, clindamycin and vancomycin were recorded from the antibiograms. Multiple logistic regression model was used to identify risk factors and account for the potential confounders.

218 patients with PJI were included in the study 142 with gentamicin-loaded bone cement and 76 in the non-ALBC group. The average age in the ALBC group was 71 ± 10years and 62 ± 12years in the comparison group (p < 0.001). Coagulase negative Staphylococci (CONS) were the most common (49%) isolated pathogens. The use of ALBC did not increase the rate of any resistant bacteria significantly (OR = 0.79 (0.42-1.48), p = 0.469). The presence of CONS was associated with higher risk of antibiotic resistance.

The current study demonstrates no increase in antibiotic resistance due to ALBC after primary TJA. Thus, the use of ALBC during primary TJA should not be feared in the context of antimicrobial resistance.

III.Repetitive transcranial magnetic stimulation (rTMS) for treatment-resistant major depression offers an alternative therapy, since more than every third patient is not responding to adequate antidepressive treatment. In this interventional study safety, symptom development and changes of serum concentrations of neurotransmitter precursor amino acids, of immune activation and inflammation markers, of brain-derived neurotrophic factor (BDNF), nitrite as well as of salivary amylase were measured before and after a frontal polar cortex stimulation using rTMS as add-on treatment in 38 patients with treatment-resistant depression. Out of these, 17 patients received sham stimulation as a control. Treatment was well tolerated with the exception of one patient of the verum group, who described discomfort during the second treatment, no serious adverse effects were observed. Improvement of depression with a significant decrease in the HAMD-7 scale (p = 0.001) was found in patients treated with rTMS, but not in sham-treated patients. Furthermore, serum phenylalanine and tyrosine dropped significantly (p = 0.03 and p = 0.027, respectively) in rTMS-treated patients. The kynurenine to tryptophan ratio (Kyn/Trp) tended to decrease under rTMS (p = 0.07). In addition, associations between concentrations of BDNF and neopterin as well as serum nitrite levels were found in patients after rTMS treatment, which indicates an influence of immune regulatory circuits on BDNF levels. In the sham-treated patients, no changes of biomarker concentrations were observed. Results show that rTMS is effective in the treatment of resistant depression. rTMS appears to influence the enzyme phenylalanine hydroxylase, which plays a central role in the biosynthesis of neurotransmitter precursors tyrosine and dihydroxyphenylalanine (DOPA).
To investigate the clinical features of spontaneous reattachment of rhegmatogenous retinal detachment (SRRRD) with diffuse retinal pigmentary changes.

This retrospective study included patients diagnosed with SRRRD. The diagnosis of SRRRD was made based on characteristic fundus findings, such as diffuse retinal pigmentary clumpings, retinal pigmentary atrophy, and convex lesion margins. The clinical features of SRRRD were also evaluated. In addition, optical coherence tomography (OCT) images and follow-up data were analyzed.

Twenty patients were included in the study. All the patients showed unilateral involvement. SRRRD predominantly involved the inferior or temporal retina (90.0%). On OCT, severe disruption of the outer retinal layers was noted in the region of SRRRD. A subretinal gliosis band was noted in 11 patients (55.0%), and an epiretinal membrane (ERM) was noted in nine patients (45.0%). In 18 patients, a mean follow-up of 24.9 ± 29.2months was performed. During the follow-up period, no definite retinal changes were noted on fundus examination or OCT.

SRRRD usually involves the inferior or temporal retina. Although severe disruption of the retinal microstructure is noted in the involved region, the condition is likely to be stable. However, long-term follow-up is required to identify progression of the ERM.

Choroidal vascular structures are likely to be affected in diabetic patients. The aim of this study was to conduct a meta-analysis of choroidal vascular structures in diabetic eyes with no diabetic retinopathy (NDR) and healthy control eyes, which was systematically evaluated by various factors involving the measurements.

This study identified clinical data from publications in PubMed and web of science until May 2020. Independent retrospective or prospective clinical studies comparing NDR and healthy control eyes regarding choroidal vascular structures were extracted. Five related studies were enrolled, cumulating in a total of 282 diabetic eyes and 511 control eyes examined in this study. Heterogeneity was statistically quantified by I2 statistics, and meta-analysis was performed using a random effects model. This study included 2 different algorisms of binarization determining the ratio of luminal areas in total choroidal areas, both of which were consolidated and called "choroidal vascular ratio."

Meta-analysis clearly showed that the choroidal vascular ratio was significantly lower in NDR eyes than in healthy control eyes (weighted mean difference =  - 2.16; 95%CI - 3.19 to - 1.13; P < 0.005). Similar results were obtained in sub-analysis based on adjustment of serum HbA1c levels and duration of diabetes.

The choroidal vascular ratio of NDR eyes was significantly lower than that of healthy control eyes. The ratio might contribute to a better understanding of the pathophysiology involved in the development of diabetic retinopathy, although there was some heterogeneity in primary analysis studies.

To identify the potential genes in human trabecular meshwork (TM) related to primary open-angle glaucoma (POAG).

First, long noncoding RNA (LncRNA) and mRNA expression profiles in TM samples from 4 control subjects and 4 POAG patients were accessed by microarray analyses. Then, twenty lncRNAs were validated by real-time quantitative PCR in the same samples from microarray analyses. Finally, eight highly expressed lncRNAs were further tested by real-time quantitative PCR in TM from 8 normal controls and 19 POAG patients. Expression data were normalized and analyzed using the R software. Pathway analyses were performed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis.

A total of 2179 lncRNAs and 923 mRNAs in the TM of POAG patients were significantly upregulated, and 3111 lncRNAs and 887 mRNAs were significantly downregulated. ENST00000552367, ENST00000582505, ENST00000609130, NR_029395, NR_038379, and ENST00000586949 expression levels were significantly higher in the TM from a different cohort of POAG patient than normal controls.

ENST00000552367, ENST00000582505, ENST000006091- 30, NR_029395, NR_038379, and ENST00000586949 may play essential roles in the development of POAG.

This study aimed to assess and compare changes in the alveolar dead space fraction (AVDSf) in the immediate postoperative period with outcomes in children with CHD who underwent repair on CPB. A single-center retrospective review study of critically ill children with CHD, younger than 18 years of age admitted to the Pediatric Intensive Care Unit (PICU) after undergoing surgical repair on CPB and received invasive mechanical ventilation for at least 24 h. One hundred and two patients were included in the study. Over the first 24 h, mean AVDSf was significantly higher in patients who had longer hospital length of stay (LOS) (> 21 days) p = 0.02, and longer duration of invasive mechanical ventilation (DMV) (> 170 h) p = 0.01. Cross-sectional analyses at 23-24 h revealed that AVDSf > 0.25 predicts mortality and DMV (p = 0.03 and P = 0.02 respectively); however, it did not predict prolonged hospital LOS. For every 0.1 increase in the AVDSf, the odds of mortality, DMV, and hospital LOS increased by 4.9 [95% CI = 1.45-16.60, p = 0.002], 2.06 [95% CI = 1.14-3.71, p = 0.01], and 1.43[95% CI = 0.84-2.45, p = 0.184], respectively. The area under the ROC curve at 23-24 h for AVDSf was 0.868 to predict mortality as an outcome. AVDSf > 0.25 at 23-24 h postoperatively was an independent predictor of mortality with sensitivity and specificity of 83% and 80%, respectively and was superior to other commonly used surrogates of cardiac output. In the immediate postoperative period of pediatric patients with CHD, high AVDSf is associated with longer hospital length of stay and duration of invasive mechanical ventilation. Increased AVDSf values at 23-24 h postoperatively is associated with mortality in patients with CHD exposed to CPB.
