Abstract
Locked dislocations of the glenohumeral joint are rare but often painful and are associated with limited range of motion in the shoulder. In patients of advanced age, arthroplasty is increasingly indicated as a surgical treatment option. Preoperatively, the direction of dislocation, the presence and extent of a glenoid defect, and the soft tissue situation (rotator cuff status, joint capsule) should be analyzed in a differentiated manner. Based on the above factors, we recommend the subclassification of type 2 according to Boileau: posterior locked dislocation (2a), anterior locked dislocation without glenoid defect (2b), and anterior locked dislocation with glenoid defect (2c). In the case of dorsally locked dislocation, a good clinical result can be achieved by using an anatomical endoprosthesis. For ventrally locked dislocations, we recommend using an inverse total endoprosthesis with, if necessary, bony glenoid reconstruction and transfer of the pectoralis major muscle.Level of evidence: IV.

Abstract
Proximal humeral fractures (PHF) are the third most common fracture in humans and the incidence is increasing. There are basically three treatment strategies: conservative, joint-preserving reconstructive or joint-replacing procedures. In addition to fracture morphology, patient-specific and surgeon-specific factors are particularly important when deciding on treatment. The experience and training of the surgeon also play a decisive role. In the case of joint-preserving treatment, the risk of osteosynthesis failure and of sequelae of the fracture must always be assessed. If conservative or reconstructive treatment methods are not promising, the joint-replacing procedure is the treatment of choice. The anatomical fracture prosthesis is only indicated, if at all, for young patients with a destroyed humeral head with a preserved rotator cuff and large fragments of the tuberosities. In advanced age, the implantation of a reverse endoprosthesis is increasingly used for dislocated, multifragmentary PHF. In both procedures, the anatomical healing of the tuberosities has a significant impact on the functional outcome.

Continued anti-VEGF treatment does not prevent recurrences in eyes with stable neovascular age-related macular degeneration using a treat-and-extend regimen: a retrospective case series. Eye (Lond) 2022; 36:862-868. [PMID: 33941877 PMCID: PMC8956692 DOI: 10.1038/s41433-021-01562-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Accepted: 04/15/2021] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND The continuation of anti-vascular endothelial growth factor (anti-VEGF) treatment after achieving stability in patients with neovascular age-related macular degeneration has generally been advocated. In our own patients, we thought to assess whether continued anti-VEGF treatment is capable of preventing recurrences. METHODS In this retrospective observational case series, patients with stable disease either opted to continue treatment every 12-14 weeks (Group 1) or stopped treatment with subsequent follow-up visits every 8-12 weeks (Group 2). RESULTS Of the 103 eyes of 103 patients achieving stability, 49 eyes continued treatment (Group 1), whereas treatment was stopped in 54 eyes undergoing regular follow-up (Group 2). Recurrent disease was observed in 21 (42.9%) and 33 (61.1%) cases in Group 1 and Group 2, respectively (p = 0.08). Time between achieving stable disease and recurrence was comparable between Group 1 and Group 2 (11.1 ± 8.2 months vs. 9.2 ± 6.7 months; p = 0.43). The number of visits between achieving stability and disease recurrence was similar, but not the number of injections (3.5 ± 2.0 vs. 0.2 ± 0.4; p < 0.001). CONCLUSIONS Continuing anti-VEGF therapy after achieving functional and morphological stability every 12-14 weeks does not prevent recurrences. Patients deserve to be informed of a potential lifetime risk of recurrences, even under continued therapy.

Visual Outcome after Intravitreal Anti-VEGF Therapy for Macular Neovascularisation Secondary to Sorsby's Fundus Dystrophy: A Systematic Review. J Clin Med 2021; 10:2433. [PMID: 34070857 PMCID: PMC8198854 DOI: 10.3390/jcm10112433] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 05/24/2021] [Accepted: 05/27/2021] [Indexed: 12/31/2022] Open
Abstract
The aim of this paper is to summarise our own and to review published experience regarding the long-term outcome of intravitreal treatment for macular neovascularisation (MNV) secondary to Sorsby's fundus dystrophy (SFD). A systematic literature search using the MeSH terms [Sorsby] and [anti-vascular endothelial growth factor (VEGF)] was conducted in NCBI/PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), ScienceDirect, Google Scholar and ClinicalTrials.gov to identify publications reporting anti-VEGF treatment outcomes in SFD. Treatment outcomes were extracted for this meta-analysis from 14 publications and an own patient reporting a total of 31 cases with a mean follow-up (FU) of 54 months. Both eyes were affected in ten (32.3%) instances. Heterogenous reporting limited the comparability of the outcomes. All papers in common, however, reported satisfied to excellent responses to anti-VEGF therapy if patients were diagnosed and treated immediately after onset of symptoms. Of 20 eyes, for which visual acuity was reported before and after treatment, five worsened and seven improved by more than 1 line, whereas eight eyes maintained their function by end of the follow up, and 11 eyes (55%) maintained a driving vision (Snellen VA ≥ 0.5). Of six eyes with a VA < 0.5, VA improved in one to VA ≥ 0.5, whereas of 14 eyes with an initial VA ≥ 0.5, this dropped to <0.5 despite therapy. In MNV secondary to SFD, the delay between first symptoms and access to anti-VEGF treatment determines subretinal scar formation and thereby, functional prognosis. If treated early, this is generally favourable under regular controls and a consequent anti-VEGF treatment of MNV activity.

How are social stressors at work related to well-being and health? A systematic review and meta-analysis. BMC Public Health 2021; 21:890. [PMID: 33971850 PMCID: PMC8111761 DOI: 10.1186/s12889-021-10894-7] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Accepted: 04/22/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Social relationships are crucial for well-being and health, and considerable research has established social stressors as a risk for well-being and health. However, researchers have used many different constructs, and it is unclear if these are actually different or reflect a single overarching construct. Distinct patterns of associations with health/well-being would indicate separate constructs, similar patterns would indicate a common core construct, and remaining differences could be attributed to situational characteristics such as frequency or intensity. The current meta-analysis therefore investigated to what extent different social stressors show distinct (versus similar) patterns of associations with well-being and health. METHODS We meta-analysed 557 studies and investigated correlations between social stressors and outcomes in terms of health and well-being (e.g. burnout), attitudes (e.g. job satisfaction), and behaviour (e.g. counterproductive work behaviour). Moderator analyses were performed to determine if there were differences in associations depending on the nature of the stressor, the outcome, or both. To be included, studies had to be published in peer-reviewed journals in English or German; participants had to be employed at least 50% of a full-time equivalent (FTE). RESULTS The overall relation between social stressors and health/well-being was of medium size (r = -.30, p < .001). Type of social stressor and outcome category acted as moderators, with moderating effects being larger for outcomes than for stressors. The strongest effects emerged for job satisfaction, burnout, commitment, and counterproductive work behaviour. Type of stressor yielded a significant moderation, but differences in effect sizes for different stressors were rather small overall. Rather small effects were obtained for physical violence and sexual mistreatment, which is likely due to a restricted range because of rare occurrence and/or underreporting of such intense stressors. CONCLUSIONS We propose integrating diverse social stressor constructs under the term "relational devaluation" and considering situational factors such as intensity or frequency to account for the remaining variance. Practical implications underscore the importance for supervisors to recognize relational devaluation in its many different forms and to avoid or minimize it as far as possible in order to prevent negative health-related outcomes for employees.

Disease stability and extended dosing under anti-VEGF treatment of exudative age-related macular degeneration (AMD) - a meta-analysis. Graefes Arch Clin Exp Ophthalmol 2021; 259:2181-2192. [PMID: 33528645 PMCID: PMC8352813 DOI: 10.1007/s00417-020-05048-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 12/02/2020] [Accepted: 12/04/2020] [Indexed: 12/21/2022] Open
Abstract
PURPOSE To assess disease stability (absence of intra- and/or subretinal fluid) and the portion of eyes being capable to extend their treatment interval to ≥ 12 weeks in exudative age-related macular degeneration (AMD). METHODS A systematic literature search was performed in NCBI, PubMed, CENTRAL, and ClinicalTrials.gov to identify clinical studies reporting treatment outcomes for ranibizumab, aflibercept, and brolucizumab in exudative AMD under a treat-and-extend protocol and a follow-up of ≥ 12 months. Weighted mean differences and subgroup comparisons were used to integrate the different studies. RESULTS This meta-analysis refers to 29 published series, including 27 independent samples and 5629 patients. In the pooled group, disease stability was reported in 62.9% and 56.0%, respectively, after 12 and 24 months of treatment, whereas treatment intervals were extended to ≥ 12 weeks in 37.7% and 42.6%, respectively. Ranibizumab, aflibercept, and brolucizumab differed regarding their potential to achieve disease stability (56.3%, 64.5%, and 71.5% after 12, and 50.0%, 52.7% and 75.7% after 24 months; p = < 0.001) and to allow an interval extension to ≥ 12 weeks (28.6%, 34.2%, and 53.3% after 12, and 34.2%, 47.7%, and 41.7% after 24 months; p = < 0.001). CONCLUSION The portion of eyes achieving disease stability regressed in the second year, whereas the portion of eyes under a ≥ 12-week interval increased. This discrepancy may reflect the challenges in balancing between under-treatment and a reduced treatment burden.

Risks and Challenges in Interpreting Simultaneous Analyses of Multiple Cytokines. Transl Vis Sci Technol 2020; 9:27.

Abstract
Purpose To determine the inherent risks of handling results below the lowest detectable value in the analysis of multiple cytokines in the aqueous humor of patients with retinal diseases by comparing possible statistical strategies to lower the risk of mis interpretation or over interpretation of results. Furthermore, in analyzing multiple cytokines simultaneously, the challenge of multiple comparison arises. Methods The analyses were based on parallel testing of 43 cytokines in 58 aqueous humor samples from patients with macular hole or epiretinal membrane. Substitution of values below the detection limit with 0.1 ×, 0.5 ×, or 1.0× of the lowest level of quantitation was compared with handling as missing value. The impact of correction for multiple comparisons was assessed using the Holm correction. Results When comparing macular hole with epiretinal membrane, not substituting the missing data revealed a difference (P < 0.05) for five compared with wight cytokines after their substitution, indicating an increased risk for under-estimating group differences (type II error). Correcting for multiple comparisons revealed a relevant risk of over estimating group differences (type I error). Conclusions Physiologic cytokine concentrations in ocular fluids typically range at or below the lowest level of quantitation. Handling of results below this cutoff as missing leads to increased type II errors. Not correcting for multiple comparisons increases the risk of a type I error. Taken together, both harbor a systematic inherent risk of misinterpretation of the results. Translational Relevance Ignoring the inherent risks of data misinterpretation in analyses of ocular fluid samples may result in mis leading conclusions regarding their biological relevance.

Abstract
PURPOSE The aim of this study was to compare neovascular age-related macular degeneration (nAMD) treatment outcomes between ophthalmological practices and a specialized macula clinic. METHODS In this case series, we included 347 treatment-naïve eyes with nAMD (332 patients). All patients received intravitreal anti-VEGF treatment using ranibizumab or aflibercept at the discretion of the treating physician using a treat-and-extend protocol either by one of 28 practice-based ophthalmologists (group 1; n = 215 eyes) or at a macula clinic (group 2; n = 132 eyes) over 24 months. RESULTS Baseline characteristics of the patients in the two groups, including age, initial BCVA (group 1 58.2 ± 18.5, group 2 60.8 ± 16.1 ETDRS letters; p = 0.32), and baseline CRT, were comparable. By end of the observation period, both groups presented similar BCVA (group 1 67.4 ± 19.3, group 2 66.8 ± 17.2 letters; p = 0.51), visual gains (group 1 7.8 ± 16.9, group 2 5.8 ± 14.4 letters; p = 0.11), CRT values (group 1 259.6 ± 80.5, group 2 277.4 ± 87.1 μm; p = 0.10), and number of injections (group 1 13.0 ± 4.5, group 2 11.6 ± 4.1 injections; p = 0.09), as well as portion of eyes with stable disease (absence of any intraretinal fluid and absence or stability of subretinal fluid and pigment epithelial detachment: group 1 78% (n = 128), group 2 75% (n = 95); p = 0.63). However, there was a significant difference regarding the number of examinations (group 1 12.8 ± 5.0, group 2 9.7 ± 3.1 visits; p = 0.0005). CONCLUSIONS nAMD treatment delivered by practice-based ophthalmologists is reasonable regarding functional outcomes and reduces the indirect treatment burden, which is partially outweighed by significantly more clinical examinations in ophthalmological practices.

Abstract
This actigraphy study tests whether daily work stressors (time pressure, social stressors), work resources (control, social support) and mental detachment from work predict sleep quality, when controlling for demands and control after work. Fifty-two railway employees participated during five consecutive workdays by completing diary questionnaires and wearing an actigraphy device. The results confirmed that social stressors from supervisors predicted more frequent sleep fragmentation and lower sleep efficiency the following night. Higher levels of daily time control at work predicted shorter sleep-onset latency and better self-reported sleep quality. Leisure time control as a covariate turned out to be a private resource, followed by fewer awakenings the following night. Detachment after work related negatively to social stressors and time pressure at work but was unrelated to indicators of sleep quality; detachment after work neither mediated nor moderated the relationship between social stressors from supervisors and sleep quality. Work redesign to increase time control and reduce social stressors is recommended to preserve daily recovery in railway employees. Practitioner summary: Sleep is important to renew health- and safety-related resources in railway employees. This diary and actigraphy study shows that higher daily work stressors were antecedents of lower sleep quality the following night, while more time control was followed by better sleep quality. Work redesign could promote health and safety by improving sleep quality.

Abstract
Purpose To compare the effect of adding a corticosteroid or switching to another anti-VEGF treatment in patients with exudative age-related macular degeneration (eAMD) with persisting intraretinal fluid on anti-VEGF monotherapy. Methods This retrospective, interventional case series involved 43 pseudophakic eyes with eAMD and persistent intraretinal fluid on anti-VEGF treatment that switched treatment to a combination of Ozurdex® or Triamcinolone and anti-VEGF therapy (group 1) or to another anti-VEGF agent (group 2). The number of injections, time to re-injection, change in central retinal thickness (CRT), and best-corrected visual acuity (BCVA) from 12 months prior to 12 months after switch to third-line therapy were defined as primary outcomes. Results Whereas the treatment demand was reduced (from 8.8±2.2 to 4.6±2.9 injections; p=0.001) and the re-injection interval extended in group 1 (from 1.5±0.4 months to 4.4±3.8 months; p=0.001), these parameters did not change in group 2 (7.4±1.6 to 7.3±2.2; p=0.90 and 1.7±0.3 months to 1.9±0.8 months; p=0.75). Mean CRT decreased from 455.7±30.1 and 427.6±36.0µm (groups 1 and 2, respectively) to 359.1±38.2 and 303.1±44.4µm (intergroup p=0.03). The mean baseline BCVA of 62.6±3.8 letters (group 1) and 63.0±1.9 letters (group 2) remained stable under therapy in both groups (intergroup p=0.67). Conclusion In eyes with eAMD with persistent intraretinal fluid on anti-VEGF monotherapy despite frequent re-injections, corticosteroids achieved a similar functional and morphological outcome over 12 months as switching to another anti-VEGF therapy, but with a reduced injection burden. In selected cases, corticosteroid treatment may thus be an option for third-line therapy in refractory exudative AMD.

Abstract
BACKGROUND Pathologic conditions of the long biceps tendon can be found within treatment of proximal humeral fractures or as a source of pain after surgery. However, simultaneous surgical treatment at the index surgical intervention is so far not well established. The purpose of this study is to evaluate the results of a simultaneous biceps treatment during plate osteosynthesis of proximal humeral fractures. MATERIALS AND METHODS Twenty-seven patients were included into this study. In 14 patients (high cosmetic and functional shoulder demand) a biceps tenodesis (LHB-TD) was carried out (7 women, 7 men; ø57 years). In 13 patients (12 women, 1 man; ø72 years) a biceps tenotomy (LHB-TT) was performed. In addition to the range of motion (ROM), the Constant score and the LHB score were evaluated. RESULTS All 27 patients were investigated after a mean follow-up of 25 months (range: 18-32 months). The ROM did not reveal any significant differences in either group. The Constant score was significantly decreased compared to the non-affected side (CS) without differences between the groups (LBS-TT 77 ± 9 vs. LBS-TD 77 ± 14; LBS-TT (CS) 82 ± 4 vs. LBS-TD (CS) 87 ± 4). The LHB score showed excellent results for both groups without significant differences (LBS-TT 98 ± 3 vs. LBS-TD 93 ± 10). In one patient of each group, an examiner-dependent upper arm deformity was detected. No patient complained of a subjective cosmetic deformity. CONCLUSION The simultaneous surgical treatment of the LHB during plate osteosynthesis of proximal humeral fractures shows good clinical and cosmetic results. In a preselected patient population (cosmetic and functional demand) the kind of treatment (LHB tenotomy or LHB tenodesis) is indifferent.

Abstract
PURPOSE To identify disease-specific cytokine profile differences in the aqueous humor (AH) (other than the vascular endothelial growth factor) between patients with dry and treated wet age-related macular degeneration (AMD) and healthy controls. METHODS This retrospective study drew on a case-series of patients diagnosed with dry AMD (n = 25) and treated wet AMD (n = 19), as well as on healthy controls (no systemic therapy; n = 20) undergoing phacoemulsification or vitrectomy. Samples of AH and serum were collected in parallel at the beginning of surgery. The levels of 43 cytokines were simultaneously determined using the Bio-Plex® multiplex beads system. Differences between the three groups were statistically compared using the Kruskal-Wallis H-Test after applying the Bonferroni correction for multiple comparisons (p<0.0012). RESULTS The concentrations of three cytokines were elevated in the AH of patients with dry AMD (CXCL6; p = 0.00067) and treated wet AMD (CXCL5, CXCL6, MIG/XCXL; all p<0.001) relative to those in the healthy controls. No other differences between the three groups were identified. The AH levels of seven cytokines (16%), including CXCL6, ranged below the lower limit of quantitation of the assay. Without the correction for multiple comparisons (p<0.05), the levels of 31 of the 43 cytokines in the AH of patients with AMD would have differed significantly from those in the control. The systemic cytokine profiles (serum) were similar in all three groups. CONCLUSIONS No systematic differences in the AH cytokine environment were identified between patients with dry AMD and those with treated wet AMD. This finding might indicate that AMD is either the result of a persistent imbalance in the physiological tissue milieu, or that the localized process induces no significant change in the cytokine environment of the anterior ocular segment.

Abstract
In recent years, the understanding of shoulder fractures has changed due to the progress of arthroscopy. In addition to the cosmetic result, the access morbidity, particularly the integrity of the subscapularis muscle in glenoid and scapular fractures, must be mentioned as an advantage of a minimally invasive approach. Furthermore, necessary secondary interventions, e. g. hook plate removal, can be prevented or minimized by modern implants and arthroscopic techniques.However, the available data and publications are almost exclusively limited to technical notes or small case series, so statements about faster recreation or potential reduction of infection risk cannot be made. Whether addressing concomitant injuries has an effect on the clinical and functional outcome is also unclear at the present time.

Abstract
PURPOSE To compare the cyto- and chemokine profiles in the aqueous humor of PEXS eyes in the absence or presence of secondary glaucoma with or without luxation of the intraocular lens (IOL). METHODS Samples of aqueous humor were collected intraoperatively from 20 healthy controls and from 73 eyes with PEX-syndrome, which was manifested in the absence of any other local or systemic desease. The latter group was sub-devided into eyes with an early form of PEX-syndrome in the absence of complications (PEX, n = 33), those with a late form of PEX-syndrome and glaucoma (PEXG, n = 30), and those with a late form of PEX-syndrome with luxation of the IOL that required surgery (PEXL, n = 10). The samples were analyzed in parallel after storage at -80°C. The levels of 40 cytokines were simultaneously quantified using the Bio-Plex® multiplex beads system. The inter-group data were statistically compared using the Kruskal-Wallis test (p ≤ 0.01). RESULTS PEX and PEXG were comparable in their cytokine profiles for all 40 cytokines, whereas the cytokine profile in PEXL-eyes revealed higher levels of all but 5 cytokines (CXCL13, CCL27, IL-2, CCL3, CCL20; p ≤ 0.01). This latter finding is indicative of a non-specific inflammatory reaction in the context of IOL-luxation. The concentrations of 6 cytokines lay below the detection limit in all groups. CONCLUSIONS The local up-regulation of 85% of the detectable cytokines in the aqueous humor of PEXL-eyes may be linked either with a progression of the disease or a breakdown of the antero-posterior barrier in the context of IOL-luxation.

Isoforms of TGF-β in the aqueous humor of patients with pseudoexfoliation syndrome and a possible association with the long-term stability of the capsular bag after cataract surgery. Graefes Arch Clin Exp Ophthalmol 2017; 255:1763-1769.

Abstract
BACKGROUND Pseudoexfoliation syndrome (PEXS) may go along with capsular bag shrinkage and luxation. In the present study, we focus on an association of isoforms of TGF-β with capsular bag luxation. METHODS Aqueous humor was collected intraoperatively from 20 healthy controls and from 73 otherwise healthy patients with PEXS [PEXS without complications (PEX, n = 33), late PEXS with glaucoma (PEXG, n = 30) and with IOL and capsular bag luxation (PEXL, n = 10)]. The concentrations of TGF-β1, TGF-β2 and TGF-β3 were compared using the Bio-Plex® multiplex beads system based on the non-parametric Kruskal-Wallis H test (p < 0.01). RESULTS Concentrations of TGF-β 1, TGF-β 2 and TGF-β 3 were higher in the sub-groups PEX and PEXG than in controls (TGF-β 1; p = 0.009 and 0.0005; TGF-β 2; p = 0.002 and 0.005 and TGF-β 3; 0.0005 and 0.0005; respectively), whereas for TGF β2, no significant difference between controls and PEXL was revealed (p = 1.0). TGF-β2 concentrations were elevated in a similar degree in early PEX and PEXG, but not in PEXL compared to controls (p = 0.002). The concentrations of of TGF-β 1 and TGF-β 3 increased in parallel with the progression of disease. The levels of TGF-β 3, however, did not attain pathophysiological levels (>100 pg/ml) in any group. CONCLUSIONS A stage-dependent increase in the concentrations of TGF-β1 and TGF-β3, but not of TGF-β2, accords to the shrinkage of the capsular bag. This could increase the tension on the zonular fibers and contribute to luxation of the capsular bag.

Abstract
PURPOSE Comparative data appertaining to the long-term effects of Aflibercept or Ranibizumab in newly diagnosed cases of neovascular age-related macular degeneration (nAMD) over follow-up periods exceeding 12 months in clinical routine are scarce. METHODS In this retrospective comparative analysis, a case series of patients with treatment-naïve nAMD and requiring anti-vascular endothelial growth factor (VEGF) therapy in a routine clinical setting were treated with either Aflibercept [Afl (n = 106)] or Ranibizumab [Ran (n = 47)]. During the drug-loading phase, 3 monthly injections were administered. Thereafter, a treat-and-extend protocol was pursued for a maximum of 24 months. Ran was administered predominantly in eyes with classical lesions; Afl was administered in all others. The primary outcome parameters included anatomical and functional stability after 24 months. RESULTS Patients were comparable regarding age, gender distribution, and lens status. Fewer patients presented with intraretinal fluid in the Afl- than in the Ran group at diagnosis (46.2% vs. 67.4%; P = 0.02), but not after the drug-loading phase. After the drug-loading phase, visual acuity [-4.2 letters (Afl) vs. -4.5 letters (Ran); P = 0.78] and the central foveal thickness remained stable. Linked to the lesion type, the number of scheduled clinical visits during the course of 24 months was higher for the Ran- than for the Afl group [11.9 ± 4.7 visits (Ran) vs. 8.4 ± 3.1 visits (Afl); P = 0.0005]. However, the total number of injections was similar [10.5 ± 2.8 (Ran) vs. 11.7 ± 3.6 (Afl); P = 0.06]. CONCLUSIONS Based on tailoring according to the lesion type in cases of nAMD, the anatomical and the functional outcomes of treatment with either Afl or Ran were comparable for a maximum of 2 years.

Exploring Supervisor-Related Job Resources as Mediators between Supervisor Conflict and Job Attitudes in Hospital Employees. Saf Health Work 2016; 8:19-28.

Abstract
BACKGROUND Conservation of resources theory assumes loss of resources as a cause of job strain. In hospital work, conflicts with supervisors are tested to predict lower resources, that is, supervisory social support, participation possibilities, and appreciation. All three resources are expected to predict, in turn, experienced stress (job strain) and lower job satisfaction, lower affective commitment, and a higher resigned attitude towards the job (job attitudes). METHODS The sample included 1,073 employees from 14 Swiss hospitals (n = 604 nurses, n = 81 physicians, n = 135 medical therapists, and n = 253 technical and administrative staff). Of the total sample, 83.1% were female and 38.9% worked full-time. The median tenure was between 7 years and 10 years. Constructs were assessed by online questionnaires. Structural equation modeling was used to test mediation. RESULTS Structural equation modeling confirmed the negative association of conflict with supervisors and job resources. Tests of indirect paths to resources as a link between conflicts with supervisors and job attitudes were significant. For nurses, social support, participation and appreciation showed a significant indirect path, while among medical technicians the indirect paths included social support and appreciation, and among physicians only appreciation showed a significant indirect path. In medical therapists no indirect path was significant. Job resources did not mediate the link between conflict with supervisors and stress in any occupational group. CONCLUSION Conflicts with supervisors are likely to reduce job resources and in turn to lower job attitudes. Work design in hospitals should, therefore, address interpersonal working conditions and conflict management in leadership development.

Abstract
INTRODUCTION The long head of biceps tendon (LHB) score was designed to clinically assess LHB pathologies. Purpose of this study was to prospectively assess patients with LHB pathologies preoperatively and after LHB surgery using the LHB score. MATERIALS AND METHODS Fifty-seven patients (29 f/28 m, Ø age 61.0 years), showing clinical signs of LHB pathologies, were prospectively included into this study. In 43 patients LHB pathologies could be confirmed intraoperatively. Among these, in 26 patients a biceps tenodesis (group I; 8 f/18 m, Ø age 61.2 years), and in 17 patients a biceps tenotomy was performed (group II; 12 f/5 m, Ø age 64.2 years). In 14 patients no intraoperative correlate concerning the biceps symptoms could be found (group III; 9 f/5m, Ø age 56.8 years). In these patients no further LHB treatment was carried out. The clinical evaluation contained the Constant score (CS) as well as the LHB score preoperatively and 2 years postoperatively. RESULTS The CS improved significantly in all the three groups [group I: 41.7 (20-70) to 81.3 (62-100); group II: 42.2 (18-66) to 75.3 (41-84); group III: 45.7 (22-77) to 72.9 (48-85)] (p < 0.05). Also the LHB score increased significantly in all three groups [group I: 74.3 (41-97) to 94.2 (80-100); group II: 73.4 (57-97) to 84.2 (49-100); group III: 71.1 (58-80) to 90.8 (70-100)] (p < 0.05). Compared to group II, group I showed significant better results in the total LHB score and in the cosmetic result (p < 0.05). CONCLUSIONS We recommend that patients with LHB pathologies are evaluated using the LHB score, since it provides LHB related information and is a proper tool to assess the clinical outcome after surgery. However, the score is not appropriate to detect LHB pathologies preoperatively. LEVEL OF EVIDENCE II.

Abstract
BACKGROUND Immobilization of the shoulder in 60 ° external rotation and 30 ° abduction after primary anterior shoulder dislocation has been shown to allow anatomical reduction and potential healing of the capsule-labrum complex. The purpose of the present study was to evaluate commercially available shoulder braces concerning functionality and comfort as well as for potential problems. METHODS In this study ten healthy subjects (6 female, 4 male and average age 23 years) tested four braces: 1. Omo Immobil (Ottobock), 2. Quadrat (DJO Global), 3. MP Airplane Axilla (Horst Rattenhuber GmbH) and 4. ARC XR (Bledsoe Brace Systems) with respect to functionality and comfort. Each subject completed simulated activities of daily living (ADLs) and a the end of each ADL the subject evaluated comfort, difficulty of the activities and potential pain on a points scale. The position or the change of the position were controlled by digital photographs. Additionally it was checked whether the subjects could actively change the position of the brace contrary to the desired position. RESULTS Braces 3 and 4 were rated significantly more comfortable (p < 0.05). Even the difficulty of the activities was rated lower and in particular putting on and taking off the braces was assessed to be significantly easier in comparison to braces 1 and 2. In addition, differences of potential pain were statistically significant and pain was experienced only with braces 1 and 2. The measuring of the position showed no significant differences (p > 0.05). For braces 1 and 2 the active change of the position by subjects was significantly higher and the arm could be rotated more against the favored position (p < 0.05). Between braces 3 and 4, there were no statistical differences during the whole evaluation. CONCLUSIONS Ortheses where the main joint is positioned in and not in front of the axilla or which can ensure a jointless stabilization of the shoulder or which allow an improved position by an additional sling on the opposite shoulder, are most qualified for immobilization of the shoulder in an external rotation/abduction position with respect to functionality and comfort.

Abstract
The incidence of rotator cuff tears and recurrent defects positively correlate with patient age. However, this observation has never been analysed at the cellular level. The present study aims to better understand this correlation by investigating cellular characteristics of rotator cuff tenocytes of different age groups. Additionally, previous studies reported on stimulating effects of Bone Morphogenetic Protein (BMP) -2 and BMP-7 on tenocytes. Thus, the second aim was to investigate, whether the stimulation potential of tenocytes demonstrates age-related differences. Tenocyte-like cells from supraspinatus tendons of young and aged patients were analysed for the following cell biological characteristics: cell density, cell growth, marker expression, collagen-I protein synthesis, stem cell phenotype, potential for multipotent differentiation and self-renewal. To analyse the stimulation potential, cells were treated with BMP-2 and BMP-7 in 2D-/3D-cultures. Measured parameters included cell activity, marker expression and collagen-I protein synthesis. An effect of age was seen for cell growth and stem cell potential but not on extracellular matrix level. Cells from both groups responded to BMP-7 by increasing cell activity, collagen-I expression and protein synthesis. BMP-2 led to smaller increases in these parameters when compared to BMP-7. In general, 3D-cultivation improved the stimulation compared to 2D-culture. The cell biological characteristics of tenocyte-like cells, considered important for successful restoration of the tendon-bone unit, were inferior in elderly donors. This may help explain higher rates of recurrent defects seen in elderly patients. Regarding the stimulation potential, on a cellular level young and aged patients may benefit from biological augmentation with BMPs.

Abstract
BACKGROUND Ingestion of high doses of casein hydrolysate stimulates insulin secretion in healthy subjects and patients with type 2 diabetes. The effects of low doses have not been studied. The aim of this study was to assess the effect of lower doses of a casein hydrolysate on the glucose and insulin responses to an oral glucose tolerance test in patients with type 2 diabetes. METHODS In this randomized, placebo-controlled, double-blind study, thirteen patients with type 2 diabetes (age: 58±1 years) were studied. Glucose, insulin and C-peptide responses were determined after the oral administration of 0 (control), 6 or 12 g protein hydrolysate in combination with 50 g carbohydrate. RESULTS Twelve grams of casein hydrolysate, but not 6g, elevated insulin levels and decreased glucose levels post-challenge. These changes over time were not large enough to also affect the total area under the curve of glucose and insulin. C-peptide levels did not change after both treatments. CONCLUSION Ingestion of six grams of casein hydrolysate did not affect glucose or insulin responses. Intake of 12 g of casein hydrolysate has a small positive effect on post-challenge insulin and glucose levels in patients with type 2 diabetes.

Abstract
During the past few years arthroscopic and minimal invasive techniques for stabilization of acromioclavicular (AC) joint dislocations have gained increasing interest. Well established procedures for open surgery were modified and implemented to attain an arthroscopic level. Furthermore implants were developed which enable these reconstructive techniques to be performed arthroscopically without the disadvantages of open procedures. The short to mid-term results described so far concerning the clinical and radiological outcome of arthroscopic stabilization techniques show an at least equal outcome to those presented in open surgery.

Abstract
BACKGROUND Fatigue is a common complaint in rheumatoid arthritis patients and contributes to loss of quality of life. OBJECTIVE To study the influence of hemoglobin levels and disease activity index upon fatigue in patients with rheumatoid arthritis (RA). METHODS We studied 130 RA patients for DAS 28, hemoglobin levels and fatigue as measured by FACIT F. RESULTS No association between fatigue with hemoglobin levels was observed. A positive association with DAS-28 was found. Decomposing DAS-28, no association could be detected with sedimentation rate but a positive correlation with analogical scale for general health, number of swollen and painful joints was found. CONCLUSION Although a positive association of fatigue with DAS-28 is found it appears that the most important items in connection with fatigue are swollen and tender joints as well as general health status. Hemoglobin levels were not related to fatigue in our patients.

Abstract
Shoulder instability includes a vast spectrum of different manifestations ranging from painful hyperlaxity to chronic locked shoulder dislocations. A correct diagnosis and classification is essential to establish an adequate treatment strategy. The correct use of different clinical tests and signs in combination with the corresponding imaging diagnostics allows an explicit classification and therefore the correct choice of treatment regimes in the majority of cases.

Abstract
OBJECTIVE To investigate the hypothesis that children with juvenile rheumatoid arthritis (JRA) would have more social and emotional problems than case-control classmates. METHODS Using a case-control design, children with JRA (n = 74), ages 8-14, were compared with case-control classmates (n = 74). Peer relationships, emotional well-being, and behavior, based on peer-, teacher-, parent-, and self-report scores on common measures, were compared using analysis of variance. RESULTS Relative to case-control classmates, children with JRA were similar on all measures of social functioning and behavior. Mothers reported more internalizing symptoms in the child with JRA, but child self reports and father reports showed no differences. Scores on all standardized measures were in the normal range for both the JRA and the case-control groups. CONCLUSION Children with JRA were remarkably similar to case-control children on measures of social functioning, emotional well-being, and behavior. These findings are not supportive of disability/stress models of chronic illness in childhood and suggest considerable psychological hardiness among children with JRA.

Abstract
The process of psychological adjustment to breast cancer was examined at diagnosis and at 3- and 6-month follow-ups in a sample of 80 women with Stage I-Stage IV breast cancer. At diagnosis, symptoms of anxiety/depression were predicted by low dispositional optimism, and this path was partially mediated by use of emotion-focused disengagement coping. Younger age also was predictive of anxiety/depression symptoms at time of diagnosis, and this relationship was fully mediated by magnitude of intrusive thoughts. At 3 months, changes in anxiety/depression symptoms were predicted only by intrusive thoughts. At 6 months, low dispositional optimism reemerged as a significant predictor of changes in anxiety/depression and again was partially mediated by the use of emotion-focused disengagement coping. Independent effects for problem-focused engagement and disengagement and emotion-focused engagement coping were also found at 6 months. Implications of these data for psychosocial interventions with breast cancer patients are highlighted.

Abstract
Maternal perceptions regarding the causes of a facial cleft deformity as well as the quality of support during medical interventions were surveyed with an open ended questionnaire. The sample consisted of 138 mothers of children up to 10 years of age attending a facial cleft deformity clinic. The responses were content analysed and thematically grouped. It was found that the subjects' views regarding the causes of facial cleft deformities changed markedly after attending counselling sessions. Ignorance about scientifically verified causal variables such as infections, medication, situational and hereditary factors decreased appreciably. The counselling sessions appeared to play an essential role in the subjects' understanding and coming to terms with their children's deformity. Their comments concerning the children's treatment in general hospitals as well as the facial cleft unit included both frustration and praise. Suggestions on enhancing support emphasised the need for accessible information, greater reassurance from medical staff at the general hospitals where delivery took place, the formation of support groups, speedy diagnosis and referral to a multiprofessional unit as well as being allowed to be with their children in hospital before and after surgical interventions. The results were discussed and tied to the available literature.

Abstract
After simultaneous administration of dexamethasone together with 6-hydroxydopamine or adrenergic neuronal blocking agents (alpha-methyldopa, reserpine, guanethidine) the dexamethasone-stimulated increase in renal excretion of p-aminohippurate (PAH) is distinctly diminished. The same is true for dopamine. This depressive effect could be proved by measurement of transport rates of PAH in renal cortical slices in vitro. The increase in kidney weight and in the protein content of kidney tissue in dexamethasone-treated rats is lower in rats simultaneously treated with adrenergic neuronal blocking agents of 6-hydroxydopamine. Adrenoceptor agonists and antagonists (pholedrine, orciprenaline, phentolamine, propranolol) are without influence on the dexamethasone-stimulated increase in PAH transport.

A study of unsuccessful dieters focused on a group of 50 obese subjects who had previously joined a slimming organisation, but who had dropped out. They were interviewed with emphasis on factors relating to reasons why the weight loss programmes had been abandoned. The subjects were reached through active members, who brought along unsuccessful slimmers to the group interviews. Interviews were recorded, transcribed and analysed. The results highlighted the following problem areas: motivational issues, perception of self, interpersonal/social and situational constraints, behaviour patterns, physiological concerns, and previous experience of weight loss programmes. Sample characteristics were examined with regard to relevant demographic and educational variables. Implications of the results are discussed.

Abstract
The influence of intraduodenal bile deficiency due to chronic bile duct obstruction and acute exogenous administration of bile acids on plasma cholecystokinin (CCK) and pancreatic polypeptide (PP) was investigated. Fourteen patients with tumor-induced bile duct stenosis and five healthy volunteers were given a liquid test meal. Four of the patients had a simultaneous pancreatic duct stenosis. On another day 4 g chenodeoxycholic acid were administered concomitantly with the liquid test meal in six of the patients and all controls. Basal and meal-stimulated plasma CCK did not differ between patients and controls. A pancreatic duct stenosis, which was associated with diminished plasma PP concentrations, had no influence on plasma CCK release. Exogenous bile acids significantly reduced the postprandial CCK response in both groups. Bile-induced inhibition was significantly greater in patients than in controls (75 +/- 7% and 44 +/- 11%, respectively; p less than 0.05). It is concluded that intraduodenal bile is an important modulator of the postprandial secretory activity of the CCK cell. Although chronic intraduodenal bile acid reduction in tumor-induced biliary duct stenosis did not influence plasma CCK levels, a negative feedback control of plasma CCK by acute bile acid administration could be demonstrated.
