Abstract
INTRODUCTION AND OBJECTIVES We investigated whether riboflavin self-administration by patients could be a feasible option for corneal cross-linking, given the considerable resources required to impregnate the cornea with riboflavin. We analysed whether administering riboflavin in the inferior fornix (the site of self-administration) results in non-inferior riboflavin concentrations as when applied directly on the cornea (the site of administration by medical personnel). PATIENTS AND METHODS We conducted a prospective study to evaluate riboflavin concentrations at six time-points (baseline, 5, 15, 30, 45 and 60min) in 18 healthy volunteers for each of two application sites: cornea and fornix. Anterior chamber riboflavin (Peschke® TE 0.25%) concentrations were measured by fluorophotometry (Fluorotron™ Master FM-2). RESULTS For the two application sites cornea and fornix, participants did not differ in terms of age and sex. At baseline, the autofluorescence in the anterior chamber was 16.7ng/mL (SD 5.5) and 14.6ng/mL (SD 4.6) (P=.221). After 30min, anterior chamber fluorescein concentrations had risen to 55.1ng/mL (SD 25.5) and 46.1ng/mL (SD 25.1) (P=.293) without a further relevant increase by 60min. CONCLUSIONS This study found that applying riboflavin drops in the inferior fornix was non-inferior to applying it directly to the cornea, based on fluorophotometric measurements of anterior chamber riboflavin concentrations. This suggests that self-application of riboflavin is feasible in terms of corneal riboflavin impregnation.

Abstract
Limited information exists on the use of zinc-l-selenomethionine (Zn-L-SeMet) in broiler diets and its effects on the growth performance, body temperature, mortality rates, blood profile, and gene expression, especially when animals are reared under cyclic heat stress conditions. This study aimed to investigate the impact of Zn-L-SeMet in broiler diets from 1 to 42 days of age reared under cyclic heat stress and its effects on growth performance, cloacal temperatures, mortality rate, blood parameters, and insulin-like growth factor 1 (IGF-1) and growth hormone receptor (GHR) gene expression in the breast muscle. A total of 1000 male Cobb 500® broiler chicks were randomly assigned to five treatments: 0, 0.15, 0.23, 0.47, and 1.30 mg/kg of Zn-L-SeMet. Each treatment consisted of 10 replicates with 20 birds each. No statistically significant differences in growth performance were observed from 1 to 21 days of age (P > 0.05). However, from 1 to 42 days, feed intake (FI) and feed conversion ratio (FCR) decreased linearly (P < 0.05). Cloacal temperatures showed no significant effects (P > 0.05), while overall mortality rate exhibited a quadratic response (P < 0.05), with the optimal inclusion level predicted to reduce broiler mortality at 0.71 mg/kg. Triglyceride (TRG) levels increased with 0.97 mg/kg (P < 0.05), and gama-glutamil transferase (GGT) levels decreased with the inclusion of 1.19 mg/kg (P < 0.05). No significant effects on IGF-1 and GHR gene expression were found (P > 0.05). In conclusion, the inclusion of 1.30 mg/kg of Zn-L-SeMet in diets of heat-stressed broilers improved growth performance from 1 to 42 days of age. An inclusion of 0.71 mg/kg reduced mortality rate, while 0.97 mg and 1.19 mg increased and reduced TRG and GGT levels, respectively.

Abstract
BACKGROUND Deficits in cognition like working memory (WM) are highly prevalent symptoms related to major depressive disorder (MDD). Neuroimaging studies have described frontoparietal abnormalities in patients with MDD as a basis for these deficits. Based on research in healthy adults, it is hypothesized that increased physical fitness might be a protective factor for these deficits in MDD. However, the relationship between physical fitness and WM-related neural activity and performance has not been tested in MDD, to date. Understanding these associations could inform the development of physical exercise interventions in MDD. METHODS Within a larger project, 111 (53female) MDD outpatients and 56 (34female) healthy controls performed an n-back task (0-, 1-, 2-, 3-back) during functional Magnetic Resonance Imaging. Physical fitness from a graded exercise test on a cycle ergometer was performed by 106 MDD patients. RESULTS Patients showed reduced performance particularly at high loads of the n-back WM task and prolonged reaction times at all n-back loads. A whole-brain interaction analysis of group by WM load revealed reduced neural activity in six frontoparietal clusters at medium and high WM loads in MDD patients compared to healthy controls. Analysis of covariance within the MDD sample showed that physical fitness was associated with neural activity in right and left superior parietal lobules. Externally defined Regions of Interest confirmed this analysis. CONCLUSIONS Results indicate frontoparietal hypoactivity in MDD at high demands, arguing for decreased WM capacity. We demonstrate a parietal fitness correlate which could be used to guide future research on effects of exercise on cognitive functioning in MDD.

Abstract
The objective of this work was to evaluate the behavior of zeolite against different types of corn in broiler chickens' diets. 1,200 male broiler chickens were assigned to 6 diets in a completely randomized design and a 2 × 3 factorial arrangement, consisting of 2 types of corn (higher or lower mycotoxin contamination) and the inclusion of zeolite (0; 5,000 and 10,000 g ton-1). In the period from d 1 to 21, there was an interaction (P = 0.0040) between types of corn and the inclusion of zeolite for feed conversion ratio (FCR). In the phase from 1 to 42 d, there was an interaction (P = 0.0322) on the serum levels of creatinine (CREA) and digestible gross energy (dGE); corn with lower mycotoxin level contamination (LMLC), caused a reduction in body weight gain (BWG) (P = 0.0046) and increase in the relative weight of abdominal fat (P = 0.0256). Inclusion rates of zeolite promoted an increase in the digestible CP (P = 0.0477) and digestible ash (P < 0.0001), as well as an increase (P < 0.0001) in hot carcass yield (P = 0.0433). The results indicate that the inclusion of zeolite, in the amounts used, did not alter the performance, serum levels, intestinal development and litter quality of the birds at 42 d of age. However, it was responsible for the improvement in the percentage of digestible nutrients (CP, GE, and MM).

Abstract
Two experiments were performed to evaluate the digestibility and growth performance of New Zealand White rabbits fed corn distillers' dried grains with solubles (DDGS). For the digestibility trial, 20 rabbits were housed in metabolic cages. The animals were distributed in two treatments, T1 (control diet without inclusion of DDGS) and T2 (control diet + 300 g kg-1 DDGS). For the growth performance trial, 100 rabbits (50 males and 50 females) were assigned in a factorial design 2 × 5 (2 gender × 5 inclusions of DDGS) and five replicates. The treatments were composed of diets with inclusions of 0, 60, 120, 180, and 240 g kg-1 of DDGS. The rabbits were housed at 35 days old, and the experiment lasted 35 days. The DDGS showed high digestibility for protein (74.10%) and lipids (81.51%) and a high content of digestible energy (2979 kcal kg-1). In the second trial, growth performance and carcass yield and organ relative weights were evaluated. There were no interactions between gender and DDGS inclusions (P > 0.05). A linear decrease was observed for feed intake (FI) for the period from days 35 to 50 (FI, P = 0.001) and FI and FCR from days 35 to 70 (FI, P = 0.004; FCR, P = 0.001) with the increasing levels of DDGS. Rabbits supplemented with 240 g kg-1 had lower (P < 0.05) whole carcass yield (WCY) and carcass without head yield compared with the control rabbits. DDGS is highly digestible in rabbits, and when supplemented up to 240 g kg-1 in diets, it improved FCR but reduced FI and WCY.

Abstract
A study was conducted to assess the chemical composition and apparent metabolizable energy (AME), nitrogen-corrected AME (AMEn), and their respective coefficients of dry brewery residue (DBR) for broilers. A second study was conducted to evaluate the increasing inclusions of DBR in broiler diets and its effects on growth performance, carcass traits, blood metabolites, and meat quality. In the first trial (metabolism assay), a total of 250 male broilers were assigned to 5 diets (0, 100, 200, 300, and 400 g DBR/kg) composed by 5 replications with 10 animals per cage in a completely randomized design in the period from days 11 to 21. There was an increasing linear effect for AME, AMEn, metabolizable coefficient of gross energy (MCGE), and MCGE corrected for N (MCGEn). In the second experiment, a total of 840 one-day-old male broiler chickens were assigned to 6 treatments (0, 20, 40, 60, 80, and 100 g DBR/kg) with 7 replications and 20 animals per pen, from days 0 to 42. Growth performance was determined at days 21 and 42. There was an increasing linear effect for weight gain in the period from days 0 to 21 and for feed intake from days 0 to 42. A linear decreasing effect was observed at day 21 for cholesterol and quadratic effect for uric acid (UA), aspartate aminotransferase, and albumin. At day 42, there was a quadratic effect for UA and creatinine. At day 21, an increasing linear effect was observed for protein deposition rate. In conclusion, the inclusion of DBR up to 100 g/kg improved WG in the starter phase and did not negatively affect the productive parameters of broilers from days 0 to 42.

Abstract
INTRODUCTION Osteoarthritis of the ankle is a major burden to affected patients. While tibio-talar arthrodesis has been the gold-standard regarding the treatment of osteoarthritis of the ankle joint for many years, at present total ankle arthroplasty (TAA) provides appealing clinical outcomes and is continually gaining popularity. The aim of this study was to evaluate the intermediate- to long-term clinical outcome including the survival rate of Salto Mobile Bearing TAA (Tonier SA, Saint Ismier, France). MATERIAL AND METHODS In this retrospective study intermediate- to long-term outcomes measures [Ankle Range of Motion (ROM), American Orthopaedic Foot and Ankle Score (AOFAS score) and survival rate] of 171 consecutive TAA were analysed and compared before and after surgery. Revision was defined as secondary surgery with prothesis component removal, while reoperation was defined as a non-revisional secondary surgery involving the ankle. RESULTS At a mean follow-up (FU) period of 7.2 ± 2.7 years (range 2.0 to 14.1 years) there was a significant improvement in ankle ROM (total ROM improved from 25.0° ± 15.0° to 28.7° ± 11.3°, p = 0.015; plantarflexion improved from 18.4° ± 11.7° to 20.6° ± 8.2°, p = 0.044; dorsiflexion improved from 6.6° ± 5.7° to 8.1° ± 4.9°, p = 0.011). AOFAS score increased significantly by 41 ± 15 points after surgery (43.3 ± 11.1 before and 84.3 ± 12.0 after surgery, p < 0.001). Overall survival rate within the FU was 81.3% (95% CI 75.3% to 87.3%) with any secondary surgery, 89.9% (95% CI 84.1% to 93.6%) with revision and 93.6% (95% CI 89.8% to 97.3%) with reoperation as endpoint. CONCLUSION This study endorses the previously reported appealing intermediate- to long-term outcomes of the Salto Mobile Bearing TAA. There was a significant increase in ROM and AOFAS score as well as decent implant survival at final FU.

BackgroundControlling or improving musculoskeletal disease activity of psoriatic arthritis (PsA) (eg, enthesitis and associated pain) is a treatment priority for patients, rheumatologists, and dermatologists.1 Enthesitis is the cardinal lesion in PsA and is immunogenetically and experimentally linked to the interleukin-23 (IL-23) pathway.2 Risankizumab (RZB), a humanized immunoglobulin G1 monoclonal antibody that specifically inhibits IL-23 by binding to its p19 subunit, was studied in a phase 3 adult PsA program (KEEPsAKE clinical trials).3,4 Pooled analyses from the program demonstrated the efficacy of RZB to treat enthesitis and pain associated with PsA, and increase the proportion of patients whose enthesitis resolved compared with placebo (PBO) in those patients who had an inadequate response or intolerance to ≥1 conventional synthetic disease-modifying antirheumatic drugs (KEEPsAKE 1 and 2) and/or ≤ 2 biological therapies (KEEPsAKE 2).ObjectivesTo investigate whether patients without enthesitis at baseline (BL) (Leeds Enthesitis Index [LEI] = 0 at BL) remained enthesitis-free through week (W) 52, patients with enthesitis at BL (LEI > 0 at BL) had resolution of enthesitis through W52, and if greater pain relief was achieved with RZB 150 mg in patients with enthesitis at BL vs PBO up to W24.MethodsThe study design and primary results of KEEPsAKE 1 (NCT03675308) and KEEPsAKE 2 (NCT03671148) have been previously reported.3,4 Briefly, patients were randomized to receive RZB 150 mg or PBO subcutaneously at weeks 0, 4, and 16 during a 24-week, double-blind treatment period; at W28 all patients received open label RZB 150 mg. For this post hoc analysis, the RZB 150 mg and PBO groups were pooled across the 2 studies. Pain reductions (as measured by change from BL in visual analogue scale [VAS] scores) were assessed at each time point through W24 among patients with enthesitis at BL (LEI > 0 at BL) using mixed-effect model repeated measurement analysis. Additional enthesitis analyses were calculated on the data as observed.ResultsAcross the pooled population, over 60% of patients in each treatment group had enthesitis at BL (RZB=444/707 [63%]; PBO=448/700 [64%]). Conversely, 37% (263/707) and 36% (252/700) had no enthesitis (LEI=0) at BL among those randomized to RZB and PBO, respectively. Among enthesitis-free patients at BL (LEI=0 at BL), 84.7% on PBO and 90% on RZB remained free of enthesitis through W24; by W52, approximately 93% of patients in both groups (RZB and PBO to RZB) remained enthesitis free. A numerically higher proportion of patients with enthesitis at BL (LEI > 0 at BL) treated with RZB (52.1%) achieved an enthesitis-free state at W24 vs PBO (41.8%); similar proportions achieved an enthesitis-free state at W36 and W52 during open label treatment (Figure 1). Among patients with enthesitis at BL, a significantly greater improvement in VAS pain scores was observed in patients treated with RZB 150 mg vs PBO, as early as W4 (P < .01) and increased through W24 (Figure 1; P < .001).Figure 1.ConclusionLong-term maintenance of an enthesitis-free state (LEI = 0) was similar between the RZB 150 mg and PBO groups, with approximately 93% of patients remaining free of enthesitis at W52. For LEI > 0 patients, the RZB 150-mg group had numerically more patients whose enthesitis resolved at W24, and similar proportions were observed at W52 after the open label switch. Patients with enthesitis at BL treated with RZB 150 mg had statistically greater improvements in pain compared with patients taking PBO starting at W4 through to W24.References[1]Orbai A-M, et al.

Abstract
BackgroundPsoriatic arthritis (PsA) greatly affects patient-reported health-related quality of life (HRQoL).ObjectivesTo assess the impact of risankizumab (RZB) on patient-reported outcomes (PROs) in patients with high skin burden using integrated efficacy data from two Phase III clinical trials (KEEPsAKE-1 and KEEPsAKE-2).MethodsAdult patients with PsA with inadequate response or intolerance to disease-modifying antirheumatic drugs were randomized 1:1 to receive RZB (150 mg) or placebo (PBO). Improvement from baseline in PROs (Patient’s Global Assessment of Disease Activity [PtGA] by visual analog scale [VAS], Short-Form 36 Health Questionnaire physical and mental component summary scores [SF-36 PCS and MCS], Health Assessment Questionnaire – Disability Index [HAQ-DI], EQ-5D 5-Level questionnaire [EQ-5D-5L] index and by VAS, Functional Assessment of Chronic Illness Therapy – Fatigue [FACIT-Fatigue], and pain by VAS) were assessed at Week 24 in patients with high skin burden (body surface area involvement ≥3% and Psoriasis Area Severity Index >10). Least squares mean (LSM) difference (95% confidence interval [CI]) between RZB and PBO groups based on mixed-model repeated measures regression is reported.ResultsRZB- vs PBO-treated patients demonstrated greater improvements in PROs with notable LSM differences (95% CI) between groups (P<0.01) in PtGA (-18.7 [-25.1, -12.2]), SF-36 PCS (6.3 [4.2, 8.4]) and MCS (4.4 [2.3, 6.6]), HAQ-DI (-0.4 [-0.5, -0.3]), EQ-5D-5L index (0.1 [0.1, 0.2]) and VAS (8.2 [2.5,13.9]), FACIT-Fatigue (4.9 [2.7, 7.2]), and pain (-18.9 [-25.1, -12.7]).ConclusionIn patients with PsA with high skin burden, 24 weeks of RZB treatment, as compared with PBO, improved patients’ HRQoL, including fatigue and pain.AcknowledgementsAbbVie funded the study and participated in interpretation of data, review, and approval of the abstract.

Abstract
This study evaluated the level and length of time of vitamin A supplementation and its effects on carcass and cuts yield, meat quality, and myopathies in 42-day-old broilers. A total of 1,920 birds were divided into 6 groups, and each group received a different level of vitamin A: 0; 6,000; 16,000; 26,000; 36,000 and 46,000 IU/ kg. From d 1 to 21, the treatments were distributed among 16 replicates with 20 birds. From the 22nd d on, 8 repetitions remained with the initial treatment and the others received diets with no vitamin A supplementation. Twelve birds were slaughtered per treatment to evaluate carcass and cuts yield, shear force, cooking loss, water holding capacity, and the presence of substances reactive to thiobarbituric acid. The remaining birds were slaughtered and evaluated in loco for Wooden Breast (WB) and White Striping (WS). Wings weight was affected by vitamin A levels. The duration of the vitamin A supplementation process had effects on the weight of breast, legs with a dorsal portion, and meat color in the yellow intensity (b*). Incidence of WB had higher scores in birds supplemented until 42 d of age. WS showed a quadratic response and a lower response with supplementation of 29,700 IU/ kg. Even for WS, a higher occurrence of the normal score was found in birds supplemented until 21 d of age. Minimal quadratic responses were obtained for normal, moderate, and severe scores, in supplementations of 29,301; 29,959, and 29,827 IU/ kg, respectively. WB had lower occurrence rates in birds supplemented until 21 d of age. Consequently, the severe score was more frequent when supplementation was provided until 42 d of age. The level of vitamin A and the length of time during which this supplementation was provided had influence on cuts yield, meat color and the incidence of WB and WS of the 42-day-old birds.

Abstract
OBJECTIVE Obsessive-compulsive disorder (OCD) is a complex psychiatric disorder with a substantial genetic contribution. While the specific variants underlying OCD's heritability are still unknown, findings from genome-wide association studies (GWAS) corroborate the importance of common SNPs explaining the phenotypic variance in OCD. Investigating associations between the genetic liability for OCD, as reflected by a polygenic risk score (PRS), and potential endophenotypes of the disorder, such as the personality trait harm avoidance, may aid the understanding of functional pathways from genes to diagnostic phenotypes. METHODS We derived PRS for OCD at several P-value thresholds based on the latest Psychiatric Genomics Consortium OCD GWAS (2688 cases, 7037 controls) in an independent sample of OCD patients (n = 180), their unaffected first-degree relatives (n = 108) and healthy controls (n = 200). Using linear regression, we tested whether these PRS are associated with the personality trait harm avoidance. RESULTS Results showed that OCD PRS significantly predicted OCD status, with patients having the highest scores and relatives having intermediate scores. Furthermore, the genetic risk for OCD was associated with harm avoidance across the entire sample, and among OCD patients. As indicated by mediation analyses, harm avoidance mediated the association between the OCD PRS and OCD caseness. These results were observed at multiple P-value thresholds and persisted after the exclusion of patients with a current comorbid major depressive or anxiety disorder. CONCLUSION Our findings support the polygenic nature of OCD and further validate harm avoidance as a candidate endophenotype and diathesis of OCD.

Abstract
Abstract
Objective
Poorer sleep quality is related to worse cognitive functioning in the general population and people living with HIV; however, many studies use self-report sleep questionnaires that rely on retrospective recall. This study aimed to examine the relationship between objective (wrist actigraphy) and subjective sleep quality with neurocognitive functioning.
Method
Eighty-five adults aged 50-74 years with and without HIV (HIV+ n = 53, HIV- n = 32) were recruited from the community and ongoing studies at UC San Diego. Participants completed comprehensive neuropsychological testing assessing global and domain-specific cognition. Participants wore actigraphy watches for 14 nights after neuropsychological testing to objectively assess sleep quality (i.e., total sleep time (TST), efficiency, wake after sleep onset, and sleep fragmentation). The Pittsburgh Sleep Quality Index assessed subjective sleep quality.
Results
After adjusting for demographic variables and use of sleep medications, there were no differences in any sleep quality measures by HIV status (p’s>0.05). In separate adjusted linear regression models, lower sleep efficiency (p = 0.02; 95% CI: -9.5, -1.1) and greater sleep fragmentation (p = 0.02; 95% CI: -0.82, -0.09) were associated with worse learning. Less TST was associated with worse working memory (p = 0.02; 95% CI: -9.2, -0.8). In contrast, worse subjective sleep quality was associated with worse executive function (p < 0.01; 95% CI: -1.18, -0.23) and working memory (p = 0.03; 95% CI: -1.22, -0.07).
Conclusion
Both objective and subjective sleep quality were associated with cognition in both persons with and without HIV; however, subjective and objective sleep quality were associated with different cognitive domains. Therefore, both objective and subjective sleep quality are important health behaviors to assess.

Abstract
OBJECTIVE The etiology of obsessive-compulsive disorder (OCD) is assumed to involve interactions between genetically determined vulnerability factors and significant environmental features. Here, we aim to investigate how the personality trait harm avoidance and the experience of childhood adversities contribute to OCD. METHOD A total of 169 patients with OCD, 157 healthy comparison subjects, and 57 unaffected first-degree relatives of patients with OCD participated in the study. Harm avoidance was assessed using the Temperament and Character Inventory, and the severity of childhood adversities was measured with the Childhood Trauma Questionnaire. RESULTS Both patients with OCD and relatives showed elevated levels of harm avoidance compared to controls. Furthermore, patients exhibited significantly higher scores than relatives. This linear pattern was observed throughout all subscales of harm avoidance, and remained stable after controlling for the severity of depressive and obsessive-compulsive symptoms. With regard to childhood adversities, patients with OCD reported higher levels than relatives and controls. CONCLUSION Our results provide further evidence for a diathesis-stress model of OCD. While patients and unaffected relatives share elevated levels of harm avoidance, supporting the role of harm avoidance as an endophenotype of OCD, a heightened severity of childhood adversity was only observed in patients. The assumed biological underpinnings of these findings are discussed.

Abstract
Tumour necrosis factor alpha (TNFα) has been implicated in the pathophysiology of neurodegenerative and neuropsychiatric disease, with research highlighting a role for TNFα in hippocampal and striatal regulation. TNFα signals are primarily transduced by TNF receptors 1 and 2 (TNFR1 and TNFR2), encoded by TNFRSF1A and TNFRSF1B, which exert opposing effects on cell survival (TNFR1, neurodegenerative; TNFR2, neuroprotective). We therefore sought to explore the respective roles of TNFR1 and TNFR2 in the regulation of hippocampal and striatal morphology in an imaging genetics study. Voxel-based morphometry was used to analyse the associations between TNFRSF1A (rs4149576 and rs4149577) and TNFRSF1B (rs1061624) genotypes and grey matter structure. The final samples comprised a total of 505 subjects (mean age = 33.29, SD = 11.55 years; 285 females and 220 males) for morphometric analyses of rs1061624 and rs4149576, and 493 subjects for rs4149577 (mean age = 33.20, SD = 11.56 years; 281 females and 212 males). Analyses of TNFRSF1A single nucleotide polymorphisms (SNPs) rs4149576 and rs4149577 showed highly significant genotypic associations with striatal volume but not the hippocampus. Specifically, for rs4149576, G homozygotes were associated with reduced caudate nucleus volumes relative to A homozygotes and heterozygotes, whereas for rs4149577, reduced caudate volumes were observed in C homozygotes relative to T homozygotes and heterozygotes. Analysis of the TNFRSF1B SNP rs1061624 yielded a significant association with hippocampal but not with striatal volume, whereby G homozygotes were associated with increased volumes relative to A homozygotes and heterozygotes. Our findings indicate a role for TNFR1 in regulating striatal but not hippocampal morphology, as well as a complementary role for TNFR2 in hippocampal but not in striatal morphology.

Abstract
The proliferation of the endometrium in the first half of the normal cycle is caused by the follicular hormone. The transformation into the secretion phase in the second half is caused by the hormone developed by the yellow substance of the corpus luteum. The term “menstrual” bleeding must be preserved for the discharged endometrium which has been proliferated first by the follicular hormone, and then transformed into the secretion phase (pregravid phase) by the corpus luteum hormone. The growth of the uterus in childhood and its pubescence depends on the follicular hormone (vegetative activity of the ovary), just as does the preservation of turgor in the genitals of the puberal woman. Many years ago, cyclic genital activity in the castrated animal was first produced by the injection of hormone, and this effect is now employed as a test for ovarian hormones. I succeeded eighteen months ago in producing complete menstruation in the castrated woman. The size of the doses of ovarian hormones administered is the important factor. In numerous experiments I have shown that—according to our present conceptions—very large doses of follicular hormones are required to produce the proliferation phase of the endometrium. The required dose is about 200,000 mouse units (= 1 million international units). For transformation of the proliferated endometrium into the secretion phase, 35 rabbit units of corpus luteum hormone are needed. The doses of follicular hormones up to now employed in therapeutics do not exert any traceable influence on the endometrium of the castrated woman. Neither have I noticed, that with doses of 600 or 1,000 mouse units, a shrivelling of the uterus which is due to long lasting functional troubles may be done away with. I have therefore proceeded to treat serious hormonal affections of the ovaries with very large doses of ovarian hormones. This paper reports on: ( a) The effect of the follicular hormone on the hypoplastic uterus, in primary and secondary amenorrhœa; ( b) spontaneous regulation of the cycle in secondary amenorrhœa also after treatment; ( c) the treatment of symptoms produced by castration and at the climacteric; ( d) the treatment of genital bleeding with corpus luteum hormone.

Abstract
BACKGROUND Lamellar keratoplasties, e.g. Descemet's stripping automated endothelial keratoplasty (DSAEK) and Descemet membrane endothelial keratoplasty (DMEK) are considered the procedures of choice for corneal endothelial diseases. In comparison to penetrating keratoplasty (PK) they are associated with faster visual rehabilitation, a lower risk of complications and a decreased necessity for follow-up visits, which reduces the burden on quality of life in elderly patients. In order to advise patients regarding the indications for surgery and to facilitate the follow-up management, it is important to know the most important complications associated with these keratoplasty techniques. RESULTS AND DISCUSSION The most important preoperative complication is a delayed indication for the operation. In contrast to PK, DSAEK and DMEK surgery should be provided at an earlier stage of disease as chronic edema alters the stroma and reduces the speed of visual recovery. The most important complications during or early after surgery are detached lamellae, pupillary blocks with increased pressure or air bubbles in the vitreous cavity in patients with previous vitrectomy. The main long-term complications include chronic increased intraocular pressure and immune-mediated graft rejections in DSAEK patients after reducing or stopping topical corticosteroid therapy. This article describes the potential complications of endothelial keratoplasty and provides a detailed explanation of strategies to avoid these complications.

Abstract
Most haematophagous insect vectors can also use sugar as an energy source; thus their sugar-feeding behaviour influences their longevity and blood-feeding rate and hence their vectorial capacity. Scant information is available on the sugar-feeding behaviour of Culicoides Latreille biting midges (Diptera: Ceratopogonidae), which are vectors of bluetongue and Schmallenberg viruses. The longevity of laboratory-reared Culicoides nubeculosus (Meigen) under fluctuating temperatures (16 and 28 °C) and with access to water or water and blood was on average 6.4 days and 8.9 days, respectively, which was around one third of the lifespan of siblings with access to sugar or sugar and blood (22.2 days and 27.1 days, respectively). Access to honeydew significantly increased the midge's longevity, whereas the provision of extrafloral nectaries had no impact. Females with access to sugar produced a significantly higher number of eggs (65.5 ± 5.2) than their starved sisters (45.4 ± 8.4). More than 80% of field-caught female Culicoides from the two most abundant European groups, Obsoletus (n = 2243) and Pulicaris (n = 805), were fructose-positive. Fructose-positivity was high in all physiological stages and no seasonal variability was noted. The high rate of natural sugar feeding of Culicoides offers opportunities for the development of novel control strategies using toxic sugar baits and for the monitoring of vector-borne diseases using sugar-treated FTA (nucleic acid preservation) cards in the field.

Abstract
BACKGROUND AND AIMS Obesity is associated with increased risks of cardiovascular disease, type 2 diabetes, and other chronic diseases. Prevalence estimates for metabolic disorders are well documented in many populations, but Alaska Native groups are understudied. The Western Alaska Tribal Collaborative for Health Study combines data from three Alaska Native study cohorts to assess differences in obesity prevalence and associations with cardiometabolic risk factors by sex. METHODS AND RESULTS Analyses were based upon a sample of 3985 adult Yup'ik and Inupiat participants with a mean age of 40 years. Prevalence of obesity and metabolic risk factors was assessed according to nationally recognized guidelines. Regression analysis was used to evaluate the association between obesity and cardiometabolic risk factors, including lipids, blood pressure and glucose. The prevalence of obesity (BMI ≥ 30) was significantly higher in women (40%) than men (20%). Only 18.6% of men had a waist circumference (WC) > 102 cm, while 58% of women had a WC > 88 cm (p < 0.001). Women had higher mean HDL-C and triglyceride levels compared to men, while systolic and diastolic blood pressure, LDL-C, and glucose means were higher in men than in women. In multivariate analyses, BMI and WC were significantly associated with all of the cardiometabolic risk factors, although these associations were more pronounced in men than women. CONCLUSION The high prevalence of obesity and central adiposity among AN women is an important public health concern. Differences in associations between obesity and cardiometabolic risk factors by sex warrants further investigation to develop effective intervention programs.

Abstract
PURPOSE The aim of this study was to assess whether intraoperative testing of silicone Ahmed glaucoma valves (AGVs) would identify valves with an increased risk of low postoperative intraocular pressure (IOP). METHODS In 30 consecutive cases of glaucoma surgery with AGV implantation, after priming the AGV, we intraoperatively measured the opening pressure A, closing pressure B, and re-opening pressure C using the active infusion pump of a phako-machine. IOP was checked postoperatively on the same day. Low IOP was defined as <5 mm Hg. Intraoperatively measured pressure characteristics of the valve function were analysed for their ability to predict postoperative IOP outcomes. RESULTS Opening A, closing B, and re-opening C pressures (mean, (SD)) were 18.4 (5.1), 8.3 (4.7), and 11.7 (4.8)mm Hg, respectively. Ten patients (33.3%) had low IOP. An opening pressure of ≤18 mm Hg predicted low postoperative IOP with a sensitivity (10/10) of 100% (95% CI, 69.2-100) and a specificity (13/20) of 65.0% (95% CI, 40.8-84.6). CONCLUSIONS AGVs have a high variability of opening, closing, and re-opening pressures. An opening pressure of ≤18 mm Hg, a closing pressure of ≤10 mm Hg, or a re-opening pressure of ≤11 mm Hg identified all patients with low postoperative IOP.

Abstract
PURPOSE To compare the effect, failure rate and the risks of corneal cross-linking (CXL) in keratoconus patients aged ≥35 years to patients <35 years. METHODS In 141 eyes of 116 keratoconus patients we compared the changes in best phoropter-corrected visual acuity (BCVA) and maximum keratometry values (Kmax) before and 12 months after CLX in patients aged ≥35 years (n=34, 38 eyes) to the cohort of patients below 35 years of age. RESULTS Overall, CXL significantly improved BCVA from 0.487 logMAR (95% confidence interval (CI) 0.426-0.548) by -0.197 logMAR (95% CI -0.243 to -0.150; P<0.001) and reduced Kmax from 48.96 diopter (Dpt) by -1.33 Dpt (95% CI -1.85 to -0.81: P<0.001). Age ≥35 years had no effect on the changes of BCVA (-0.02 (95% CI -0.13 to 0.09); P=0.757) or Kmax (0.58 (95%CI -0.51 to 1.68); P=0.294) as compared with younger patients. In 54 patients (55 eyes, 38.5%) aged <35 years and in 18 patients (18 eyes, 47.4%) aged ≥35 years, BCVA increased by ≥2 Snellen lines. Failure (increase in Kmax ≥1 Dpt) was observed in 17 eyes (16.5%) of patients aged <35 years and in 3 eyes (7.9%) of patients aged ≥35 years during the 12-month follow-up period. Adverse outcomes (loss of ≥2 Snellen lines) occurred in 4 (3.9%) eyes of patients aged <35 years and 1 (2.6%) eye of a patient aged ≥35 years. CONCLUSION Effects and adverse events of CXL treatment do not seem to differ between subjects younger or older than 35 years.

Abstract
Insect bite hypersensitivity (IBH) in horses represents an immunoglobulin E (IgE)-mediated hypersensitivity to salivary antigens from biting midges (Culicoides spp.). The aim of this study was to evaluate and compare the performances of IgE ELISAs using recombinant Culicoides spp. Obsoletus group salivary gland antigens or crude whole body extracts ('ObsWBE'), C. nubeculosus recombinant proteins (Culn1, 3, 4, 5, 7, 8 and 10) and Obsoletus group recombinant proteins (Culo1 and 2). IgE levels were measured in plasma of 343 Warmblood horses classified as IBH-affected (n=167) and IBH-unaffected (n=176) according to the owners' descriptions. IBH-affected horses were subdivided based on the severity of their clinical signs at sampling and whether or not their IBH history was considered to be classical. The accuracies of the tests increased when clinical signs at sampling were more pronounced or when the IBH history could be considered as classical. A combination of IgE levels against the three best performing Culicoides spp. recombinant proteins (Culn4, Culo1 and Culo2) and ObsWBE resulted in the best performing test. When IBH-affected horses showing a classical history of the disease and severe clinical signs were compared with IBH-unaffected horses, the Youden's index at the optimal cut-off for the three tests in combination was 0.67. This optimal cut-off had a sensitivity of 70%, a specificity of 97% and a total accuracy of 92%. The performance of the IgE ELISA was affected by the severity of IBH clinical signs at sampling and was improved when IgE levels against several recombinant proteins were combined.

Abstract
BACKGROUND Patients with medically unexplained symptoms (MUS) are frequent in primary care and substantially impaired in their quality of life (QoL). Specific training of general practitioners (GPs) alone did not demonstrate sustained improvement at later follow-up in current reviews. We evaluated a collaborative group intervention. METHODS We conducted a cluster randomized controlled trial. Thirty-five GPs recruited 304 MUS patients (intervention group: 170; control group: 134). All GPs were trained in diagnosis and management of MUS (control condition). Eighteen randomly selected intervention GPs participated in training for a specific collaborative group intervention. They conducted 10 weekly group sessions and 2 booster meetings in their practices, together with a psychosomatic specialist. Six and 12 months after baseline, QoL was assessed with the Short-Form 36. The primary outcome was the physical composite score (PCS), and the secondary outcome was the mental composite score (MCS). RESULTS At 12 months, intention-to-treat analyses showed a significant between-group effect for the MCS (p = 0.023) but not for the PCS (p = 0.674). This effect was preceded by a significant reduction of somatic symptom severity (15-item somatic symptom severity scale of the Patient Health Questionnaire, PHQ-15) at 6 months (p = 0.008) that lacked significance at 12 months (p = 0.078). As additional between-group effects at 12 months, per-protocol analyses showed less health anxiety (Whiteley-7; p = 0.038) and less psychosocial distress (PHQ; p = 0.024); GP visits were significantly (p = 0.042) reduced in the intervention group. CONCLUSIONS Compared to pure GP training, collaborative group intervention achieved a progressive, clinically meaningful improvement in mental but not physical QoL. It could bridge gaps between general practice and mental health care.

Abstract
PURPOSE The aim of this study was to compare postoperative pain between the open tension-free plug and patch (PP) technique and the totally extraperitoneal patch (TEP) hernioplasty. METHODS One hundred and fifty-four male patients with unilateral inguinal hernia were randomized to undergo PP and TEP from 2005 to 2009. Pain assessment was conducted using the numerical rating scale (NRS) and the McGill Pain Questionnaire preoperatively, 6, 12 and 24 months postoperatively. All patients received the same analgesic regimen and documented pain in a NRS-based 4-week diary. RESULTS Of the 154 patients 77 underwent TEP and 77 PP. Median follow-up was 3.8 years. One recurrent hernia was observed in the TEP and two in the PP group (p = 0.56). Median preoperative NRS scores were 2 and 2, 0.3 and 0.4 at 6 months, 0.1 and 0.3 at 12 months, 0.2 and 0.1 at 24 months postoperatively in the PP and TEP groups, respectively (p > 0.05). Data from the 4-week pain diaries revealed significant differences in pain intensity between the two different techniques from the second postoperative week (p < 0.05). Patients in the PP group required more additional analgesics on day four and five postoperatively (p = 0.037 and 0.015, respectively). CONCLUSIONS Our data favor the TEP technique concerning postoperative pain as primary endpoint between tension-free PP and TEP hernia repair.

Abstract
BACKGROUND Combined excimer laser correction and corneal cross-linking is a promising concept in treating keratoconus patients. Central corneal regularization represents advanced topography-guided custom ablation for ectatic corneas, aiming at correcting irregular astigmatism and at increasing the optical regularity of the corneal surface. PATIENTS AND METHODS In a prospective single centre study, 10 keratoconus patients underwent combined treatment with corneal cross-linking and central corneal regularization by an iRES-Laser. Uncorrected visual acuity at 1 and 3 months postoperatively represented the primary endpoint. RESULTS Mean preoperative uncorrected decimal visual acuity was 0.15 (± 0.28 standard deviation). Mean postoperative visual acuity was 0.28 (± 0.47) at one month and 0.24 (± 0.25) at three months, respectively. CONCLUSIONS Combined corneal cross-linking and central corneal regularization treatment has the potential to achieve a clinically significant improvement of uncorrected visual acuity.

Abstract
Obsessive-compulsive disorder (OCD) is associated with dysfunctional brain activity in several regions which are also involved in the processing of motivational stimuli. Processing of reward and punishment appears to be of special importance to understand clinical symptoms. There is evidence for higher sensitivity to punishment in patients with OCD which raises the question how avoidance of punishment relates to activity within the brain's reward circuitry. We employed the monetary incentive delay task paradigm optimized for modeling the anticipation phase of immediate reward and punishment, in the context of a cross-sectional event-related FMRI study comparing OCD patients and healthy control participants (n = 19 in each group). While overall behavioral performance was similar in both groups, patients showed increased activation upon anticipated losses in a medial and superior frontal cortex region extending into the cingulate cortex, and decreased activation upon anticipated rewards. No evidence was found for altered activation of dorsal or ventral striatal regions. Patients also showed more delayed responses for anticipated rewards than for anticipated losses whereas the reverse was true in healthy participants. The medial prefrontal cortex has been shown to implement a domain-general process comprising negative affect, pain and cognitive control. This process uses information about punishment to control aversively motivated actions by integrating signals arriving from subcortical regions. Our results support the notion that OCD is associated with altered sensitivity to anticipated rewards and losses in a medial prefrontal region whereas there is no significant aberrant activation in ventral or dorsal striatal brain regions during processing of reinforcement anticipation.

Abstract
BACKGROUND Diabetes mellitus secondary to pancreatic diseases is a condition seldom thought of in clinical practice. Yet, a high percentage of exocrine pancreatic insufficiency has been reported for the general population and especially for diabetic subjects. Thus, we investigated the prevalence of diabetes mellitus due to pancreatic diseases. METHODS In this study, we investigated 1868 patients diagnosed with diabetes mellitus who had been admitted to our hospital during the last 24 months. Patient data were diligently studied, and patients were reclassified according to the diabetes classification as proposed by the American Diabetes Association. RESULTS Among 1868 subjects, 172 patients could be classified as type 3c diabetes mellitus (9.2%). Among these were 135 diagnosed with chronic pancreatitis (78.5%), 12 with hereditary haemochromatosis, 14 with pancreatic cancer and 7 with cystic fibrosis. Thus, diabetes mellitus due to chronic pancreatitis occurred in this collective in 7.2% of all diabetic subjects. Misclassification of these patients was very common. Only 51.2% (88/172) were initially classified correctly. Most type 3 diabetes patients were initially misclassified as type 2 diabetes (69/84). CONCLUSIONS Diabetes mellitus secondary to pancreatic diseases (especially chronic pancreatitis) seems more common than generally believed with a prevalence of 9.2% among the subjects studied here. Because the awareness of this diabetes type is poor, misclassification is quite frequent. A common problem seems to be the differentiation between type 2 and type 3. Yet, the right classification of diabetes mellitus is important, because there are special therapeutic options and problems in patients with diabetes secondary to pancreatic diseases.

Abstract
BACKGROUND Corneal melting represents a serious condition that can result in corneal perforation and loss of vision. Treatment options include topical and systemic immunosuppression, cyanoacrylate gluing, and emergency keratoplasty, depending on the underlying disease and the stage of corneal melt. Recently, corneal cross-linking (CXL) has emerged as an additional treatment option. The present study evaluates whether CXL induces a clinical improvement in melting keratitis not responding to conventional treatment. HISTORY AND SIGNS Six patients undergoing CXL for corneal melting of variable origin (including bacterial, fungal and Acanthamoeba keratitis) were reviewed retrospectively. THERAPY AND OUTCOME Treatment parameters included riboflavin application following UV irradiation with a wavelength of 370 nm and an irradiance of 3 mW/cm2 for 30 minutes. Four patients with corneal melting due to contact lens-related infectious keratitis showed healing without any need for further interventions up to date. In two patients, CXL stabilized the melting cornea and facilitated additional surgical procedures. CONCLUSIONS By stabilizing corneal collagen fibres, CXL seems to represent an effective option to re-establish corneal integrity in the event of pending perforations. In established perforations, CXL facilitates further emergency procedures by stiffening the tissue.

Abstract
This paper promotes a reflection on the relationship between daily practices and consumption. Understanding how conflicts, resistance and consensus are generated from daily consumption practices opens up possibilities for reflecting on the construction of sustainability in the context of diversity, one of the landmarks of the globalized world. Within this socio-cultural context, the central issue is: can consumption generate citizenship practices? The concepts of subject and agent help one think about collective action and subjectivation processes and their interferences on the collective consuming behavior. Based on empirical data from a research carried out in the municipality of Estrela in 2007, in the Taquari Valley - Rio Grande do Sul (Southern Brazil) on local reality consumption practices, it was possible to conclude that various reasoning mechanisms and values underlie the daily consumption practices. Citizenship construction, based on consumption practices, depends on the subject's reflection capacity on his/her daily practices or on what goes through the circulation of environmental information based on sociability spaces.

Abstract
Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) has shown promise in species identification of insect species. We evaluated its potential to consistently characterize laboratory-reared biting midges of the species Culicoides nubeculosus (Meigen) (Diptera: Ceratopogonidae). Twenty-one reproducible potential biomarker masses for C. nubeculosus were identified under different experimental treatments. These treatments included the homogenization of insects in either water or known concentrations of formic acid. The biomarker masses were present independent of age, gender and different periods of storage of individuals in 70% ethanol (a standard preservation method). It was found that the presence of blood in females reduced the intensity of the MALDI-TOF pattern, necessitating the removal of the abdomen before analysis. The protein profiles of a related non-biting midge, Forcipomyia sp. (Diptera: Ceratopogonidae), and of Aedes japonicus japonicus (Theobald) (Diptera: Culicidae) mosquitoes were also examined and were distinctly different. These findings provide preliminary data to optimize future studies in differentiation of species within the Culicoides genus using MALDI-TOF MS which is a rapid, simple, reliable and cost-effective technique.

Abstract
BACKGROUND Outbreak of bluetongue virus serotype-8 (BTV-8) infection in domestic ruminants in Northern Europe. OBJECTIVE To investigate the South American camelids' (SAC) susceptibility to BTV-8 infection, their role in the epidemiology of the disease, and the use of currently available serological screening tests in SAC in an endemic region. ANIMALS Three hundred and fifty-four unvaccinated and 27 vaccinated SAC (170 llamas, 201 alpacas), ranging in age from 1 month to 17 years between June and August 2008. The SAC originated from 44 herds throughout the country, representing 10% of the Swiss SAC population. METHODS Prospective, observational study of a convenience sample of SAC. Serum samples were analyzed with 2 serological screening tests. When results diverged, a 3rd ELISA was carried out for confirmation (ID Screen Bluetongue Competition ELISA kit). RESULTS All sera from the 354 unvaccinated animals were negative in the endemic region. Reliable seroconversion was observed after administration of 2 doses of vaccine. CONCLUSIONS AND CLINICAL IMPORTANCE This study suggests a low susceptibility of SAC to BTV-8 despite the presence of the virus in the cattle and small ruminant population, indicating that SAC do not play a major role in the epidemiology of BTV-8. Furthermore, these results indicate that commercially available serological tests for BTV-8 can be used in SAC.

Abstract
BACKGROUND Bluetongue virus serotype 8 (BTV-8) has caused disease in domestic ruminants in several countries of northern Europe since 2006. In 2008 a mass-vaccination program was launched in most affected countries using whole virus inactivated vaccines. OBJECTIVE To evaluate 2 inactivated vaccines (Bovilis BTV 8; BTVPUR AlSap8) for immunogenicity and safety against BTV-8 in South American camelids (SAC) in a field trial. ANIMALS Forty-two SAC (25 Alpacas, 17 Llamas) aged between 1 and 16 years. METHODS The animals were vaccinated twice at intervals of 21 days. They were observed clinically for adverse local, systemic, or both reactions throughout the trial. Blood samples collected on days 0, 14, 21, 43, and 156 after vaccination were tested for the presence of BTV-8 virus by real time-polymerase chain reaction and of specific antibodies by competitive ELISA and a serum neutralization test. RESULTS All vaccinated animals developed antibodies to BTV-8 after the 2nd administration of the vaccine. No adverse effects were observed except for moderate local swellings at the injection site, which disappeared within 21 days. Slightly increased body temperatures were only observed in the first 2 days after vaccination. The BTV was not detected in any of the samples analyzed. CONCLUSIONS AND CLINICAL IMPORTANCE The administration of the 2 inactivated commercial vaccines was safe and induced seroconversion against BTV-8 in all vaccinated animals. The results of this study suggest that 2 doses injected 3 weeks apart is a suitable vaccination regimen for SAC.
