Horst J Koch Department of Psychiatry and Psychotherapy, HELIOS Clinic Aue – Academic Hospital of the Technical University Dresden, Aue, Germany Abstract: Psychiatric disease, particularly depression and stress disorders, worsens the outcome of cardiovascular disease by about a factor of two to three. Conversely, heart disease can also cause or aggravate affective disorders in the person concerned. Although this mind–heart interaction has been known since the 1930s, many questions about the underlying mutual pathophysiology remain. Apart from psychological stress models, inflammatory or psychoimmunology processes and metabolic or endocrinological mechanisms may be involved, as might lifestyle and drug treatments. Takotsubo, or broken-heart cardiomyopathy, which frequently occurs in response to stressful events, and post-myocardial infarction depression may serve as paradigms in seeking to understand the pathological basis of the mind–heart relationship. Keywords: broken-heart cardiomyopathy, takotsubo, post-infarction depression, mind–heart interaction, pathophysiology

The lower yield of wheat grown after wheat (second wheat) compared with the first wheat after a break crop is frequently attributed to fungal disease occurrence, but has also been found without visible disease infection; thus, other factors might be responsible for the lower yield of the second wheat. The aims of this study were to analyze the effects of growing wheat as first and second wheat after oilseed rape, as well as monoculture in a long-term field experiment over three years on (i) aboveground biomass formation, root development and nutrient acquisition during the growing season, (ii) take-all occurrence, and (iii) grain yield and yield components. Subsoil root length density of winter wheat was significantly higher after oilseed rape as pre-crop than after wheat, which was independent of take-all occurrence. Differences in wheat aboveground biomass occurred at early growth stages and were persistent until harvest. Grain yield loss correlated well with take-all disease severity in a wet year but yield differences among crop rotational positions occurred also in a dry year without visible fungal infection. Thus, an effect of the crop rotational position of wheat beyond take-all disease pressure can be assumed. Overall, wheat root length density might be the key to understand wheat biomass formation and grain yield in different crop rotational positions., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Arnhold, Grunwald, Braun-Kiewnick and Koch.)

Cover crops are supposed to decrease the soil mineral N content (N min ) during winter and increase the N supply to subsequent main crops due to mineralization of N previously prevented from leaching. However, data on N supply from cover crops grown before sugar beet have rarely been reported for Central European conditions. Therefore, our study aimed to provide information for cover crops differing in frost resistance and biomass quantity applicable for N fertilizer dressing in the subsequent main crop. In 2018/19 and 2019/20, field trials were conducted on two Luvisol sites in Germany typical for sugar beet cultivation, comprising a sequence of autumn sown cover crops grown after field pea followed by unfertilized sugar beet main crops sown in next spring. Apparent net N mineralization and the N effect of cover crops on sugar beet were calculated according to a mass balance approach including N min and sugar beet N uptake. Winter rye and oil radish revealed the greatest potential for scavenging nitrate from the soil profile while reductions caused by frost-sensitive saia oat and spring vetch were more variable. The amount of N in the cover crop biomass was negatively correlated with N min in autumn and also in spring. Thus, for environmentally effective cover cropping in Central Europe, species with a sufficiently high frost tolerance should be chosen. Despite cover crop N uptake up to 170 kg N ha -1 and C:N ratios < 20, a positive N effect on sugar beet was only found between March and July of the beet growing season and was 50 kg N ha -1 at maximum, while between August and September, net immobilization was predominant with up to 100 kg N ha -1 . Differences among crop species were not consistent across the site/years investigated. Sugar yield was lowest after rye at 3 sites/years and correlated positively with N min in spring. Correlation between yield and cover crop N effect was mostly low and inconsistent and could not be improved by a multiple regression approach. Thus, factors other than in-season N supply from cover crops apparently impacted sugar beet yield formation to a larger extent., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Koch, Grunwald, Essich and Ruser.)

Background: Quality of treatment is of increasing importance in psychiatry. Since the 1950s psychiatry has developed plenty of psychological and occupational approaches in addition to an arsenal of biological procedures. These treatment options have contributed to markedly lower the residence times in psychiatric medical centers to about 3 or 4 weeks., Method: The quality of treatment of a psychiatric clinic was evaluated on the basis of a limited number of parameters and in a short time. The data of 657 patients were evaluated., Results: The patients profited significantly from the treatment, particularly when specific therapies were available as in depression or schizophrenia. About ¼ of the patients received no psychoactive drugs. Most of the patients could be discharged from hospital within 3 weeks. The legal basis of hospitalization did not play a decisive role in the success of treatment. Most of the patients were after-treated by general practitioners., Conclusion: The result underlines the effectiveness of psychiatric treatment, but also the importance of cooperation between inpatient and outpatient treatment.

Agricultural landscapes are globally dominated by monocultures under intensive management. This is one of the main reasons for biodiversity loss and insect population decline in many regions all over the world. Agroecosystem biodiversity in these areas can be enhanced by cropping system diversification, such as crop rotations. Yet, long-term studies on effects of crop rotations on aboveground agrobiodiversity are lacking. We set up a 10-year long-term crop rotation experiment in Central Germany and monitored the temporal dynamics of aboveground arthropods over a full cultivation period to investigate influence of current and preceding crop identity and cropping system diversification on activity density, species richness, and community structure. We found that species composition was strongly influenced by currently grown crop although effect on arthropods varied between species groups. Especially, winter oilseed rape strongly affects arthropod community structure. Interestingly, we were also able to show an influence of the preceding crops, indicating an ecological memory effect in the aboveground arthropod community. Our results show that crop identity of both currently and previously grown crops in crop rotations may lead to an increase in arthropod activity density and changes in species composition. Diversified crop rotations including appropriate crops can be an easily implemented tool to increase arthropod biodiversity and biomass at large spatial and temporal scales, particularly in areas dominated by a single crop (e.g., wheat, maize). Our results may help to design optimized crop rotations for large-scale enhancement of insect biodiversity in agroecosystems., Competing Interests: None declared.

Background: Medical TV series are very popular. Media research emphasizes that watching TV has an influence on patient's expectations and estimations concerning upcoming surgery. We analyzed these associations in our own patients. We suspected that reality as presented in the media and the actual reality of hospitals are not always conceived as two different worlds., Methods: Over a 15-month period a standardized questionnaire was used to interview 162 in-house patients who had been admitted for an elective standard operation. They were interviewed 1-2 days prior to surgery and shortly before discharge from hospital. The questions aimed at their social situation and their TV viewing habits with special consideration of medical TV series., Results: The knowledge of medical TV series is highly associated with a realistic assessment of these programs (p < 0.05). Furthermore, the knowledge of these programs is correlated with patient's unrealistic estimations of upcoming surgery., Conclusion: Medical TV series have a significant influence on surgical in-house patients. Patients with knowledge of many medical TV series believe that the medical setting in these shows is realistic. This can result in false estimations concerning real surgery.

Atopic dermatitis (AD) in dogs is among the most common skin diseases in small animal practice. It is an inflammatory disease based on a genetic predisposition to develop hypersensitivity against environmental and food allergens and typical clinical signs up exposure. Treatment sometimes can be difficult and associated with adverse effects. Previous studies evaluating cholecalciferol as treatment for human AD have shown promising results. With canine AD being a good animal model for its human counterpart, it was hypothesised that cholecalciferol might have beneficial clinical effects in dogs, too. In this randomised, placebo-controlled, double-blinded eight-week cross-over study, 23 client-owned dogs received either systemic cholecalciferol (n=16), a vitamin D receptor analogue (n=8) or placebo (n=13). Blood samples for ionised calcium were obtained regularly during the study, and Canine Atopic Dermatitis Extent and Severity Index and pruritus scores, blood levels of vitamin D metabolites, measurements of skin pH and transepidermal water loss were determined before and after. Pruritus and lesion scores decreased significantly in the cholecalciferol group versus placebo. No differences in water loss or skin pH were observed. An increase in serum 25-hydroxycholecalciferol strongly correlated with a reduction in pruritus. Systemic cholecalciferol may be a viable treatment option for canine AD., Competing Interests: Competing interests: None declared., (© British Veterinary Association (unless otherwise stated in the text of the article) 2018.

In Europe, the framework for sugar beet ( Beta vulgaris L.) production was subject to considerable changes and for the future it is expected that sugar beet cultivation might concentrate around the sugar factories for economic reasons. Based on data from a national sugar beet farmers' survey and multi-year crop rotation trials, the effects of cropping interval (number of years in between two subsequent sugar beet crops) and of preceding crops on sugar yield were elucidated under current Central European management conditions. The dominating sugar beet cropping interval was ≥4 years in the farm survey with pronounced differences between regions. However, the cropping intervals 2, 3, and ≥4 years did not affect the sugar yield. Therefore, significant differences in sugar yield between regions were assumed to be caused by multiple interactions between year, site, and farmers' skills. Throughout Germany, the dominating preceding crops in sugar beet cultivation were winter wheat ( Triticum aestivum L.) and winter barley ( Hordeum vulgare L.). In the field trials, the sugar yield was 5% higher after pea ( Pisum sativum L.) compared to maize ( Zea mays L.) as preceding crop, while differences between the preceding crops pea and winter wheat, and wheat and maize were not significant. Repeated measurements of canopy development and leaf color during the growing season revealed a higher N-availability after pea as preceding crop. However, decreased growth after maize was not completely compensated for by high N-fertilizer doses. Overall, the causes for the differences in sugar yield between the preceding crops remained open. The results do not support concerns about substantial yield losses in sugar beet production due to a reduction in the cropping interval from 3 to 2 years. Nevertheless, short rotations with maize and sugar beet might increase the risk of Rhizoctonia solani crown and root rot infestation. Leguminous crops such as pea offer the potential for higher sugar beet yield with lower N-fertilizer doses.

Background and Hypotheses: The growing number of medical television series and the increasing amount of time people spend watching TV will have an influence on what they expect from their treatment in a hospital. We suspect that reality as presented in the media and the actual reality of hospitals are not always conceived of as two different worlds. Many medical TV shows present dramatic, life-threatening operations much more often than they occur in reality. Patients who frequently watch such shows might be induced to believe that even routine operations are often dangerous, which could result in higher levels of fear before such an operation. We suspect then that there is a significant relation between preoperative levels of fear and TV viewing habits., Methods: A standardized questionnaire was used to interview 162 in-house patients who had come to the hospital for an elective standard operation in a German hospital. They were interviewed 1-2 days prior to operation and shortly before discharge from hospital. The questions aimed at their social situation, their TV viewing habits with special consideration of medical TV shows, and the patients' preprocedural fear., Results: The links between levels of education, age, and gender on the one hand, and viewing habits on the other, which have been shown in cultivation research, are supported by our findings. Approximately 50% reported a relevant anxiety level above 4 (on a scale of 0-10). There is a significant association between levels of fear and TV viewing habits. Thirteen subjects (8%) indicated that they suffered the highest imaginable degree of fear, all of them frequent watchers of medical TV shows. Frequent viewers of medical TV shows were definitely more scared than all other patients (p = 0.039). The preoperative level of fear was highest in the age group of under 40 years and significantly lower (p = 0.0042) in the age group of over 70 years., Conclusion: The assumed effects of cultivation with in-house patients caused by watching TV series could be shown to be statistically significant. Watching medical TV shows increases the patients' preoperative fear., (© 2017 S. Karger AG, Basel.)

Avoiding soil compaction caused by agricultural management is a key aim of sustainable land management, and the soil compaction risk should be considered when assessing the environmental impacts of land use systems. Therefore this project compares different crop rotations in terms of soil structure and the soil compaction risk. It is based on a field trial in Germany, in which the crop rotations (i) silage maize (SM) monoculture, (ii) catch crop mustard (Mu)&#95;sugar beet (SB)-winter wheat (WW)-WW, (iii) Mu&#95;SM-WW-WW and (iv) SB-WW-Mu&#95;SM are established since 2010. Based on the cultivation dates, the operation specific soil compaction risks and the soil compaction risk of the entire crop rotations are modelled at two soil depths (20 and 35 cm). To this end, based on assumptions of the equipment currently used in practice by a model farm, two scenarios are modelled (100 and 50% hopper load for SB and WW harvest). In addition, after one complete rotation, in 2013 and in 2014, the physical soil parameters saturated hydraulic conductivity (kS) and air capacity (AC) were determined at soil depths 2-8, 12-18, 22-28 and 32-38 cm in order to quantify the soil structure. At both soil depths, the modelled soil compaction risks for the crop rotations including SB (Mu&#95;SB-WW-WW, SB-WW-Mu&#95;SM) are higher (20 cm: medium to very high risks; 35 cm: no to medium risks) than for those without SB (SM monoculture, Mu&#95;SM-WW-WW; 20 cm: medium risks; 35 cm: no to low risks). This increased soil compaction risk is largely influenced by the SB harvest in years where soil water content is high. Halving the hopper load and adjusting the tyre inflation pressure reduces the soil compaction risk for the crop rotation as a whole. Under these conditions, there are no to low soil compaction risks for all variants in the subsoil (soil depth 35 cm). Soil structure is mainly influenced in the topsoil (2-8 cm) related to the cultivation of Mu as a catch crop and WW as a preceding crop. Concerning kS, Mu&#95;SB-WW-WW (240 cm d(-1)) and Mu&#95;SM-WW-WW (196 cm d(-1)) displayed significantly higher values than the SM monoculture (67 cm d(-1)), indicating better structural stability and infiltration capacity. At other soil depths, and for the parameter AC, there are no systematic differences in soil structure between the variants. Under the circumstances described, all crop rotations investigated are not associated with environmental impacts caused by soil compaction., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

A direct soil DNA extraction method from soil samples (250 g) was applied for detection of the soilborne sugar-beet-infecting pathogen Rhizoctonia solani anastomosis group (AG) 2-2IIIB using a newly developed real-time polymerase chain reaction assay that showed specificity to AG2-2IIIB when tested against various R. solani AG. The assay showed a good relation between cycle threshold and amount of AG2-2IIIB sclerotia detected in three spiked field soils and was also able to detect the pathogen in naturally infested field soil samples. A field trial was conducted to quantify R. solani AG2-2IIIB soil inoculum potential (IP) before and after growing a susceptible and a resistant sugar beet variety as well as after subsequent growth of an expected nonhost winter rye. Plants of the susceptible sugar beet variety displayed a higher disease severity. A more than sixfold increase of the R. solani AG2-2IIIB soil IP was observed in contrast to the resistant variety that resulted in a constant IP. Growing winter rye significantly reduced soil IP to the initial level at sowing. Further research is required to better understand the interaction between disease occurrence and soil IP as well as the environmental influence on IP development.

Background: Noninflammatory alopecia is a frequent problem in dogs. Estrogen-induced alopecia is well described in dogs, with estrogen producing testicular tumors and canine female hyperestrogenism., Objectives: To increase awareness that extensive alopecia in dogs can be caused by exposure to estradiol gel used by owners to treat their postmenopausal symptoms., Animals: Skin biopsies from five dogs with extensive alopecia were examined., Methods: Owners were asked for a thorough case history, including possible exposure to an estradiol gel. Complete blood work and serum chemistry panel analysis were performed to investigate possible underlying causes. Formalin-fixed skin biopsy samples were obtained from lesional skin and histopathology was performed., Results: All owners confirmed the use of a transdermal estradiol gel and close contact with the affected dogs before development of alopecia. Histopathologic examination showed a similar picture in all five dogs. Most hair follicles were predominantly either in kenogen or telogen and hair follicle infundibula showed mild to moderate dilation. Hair regrowth was present in all five dogs after the exposure to the estradiol gel was stopped or minimized. Blood work and serum chemistry panel were within normal limits in all cases. One dog had elevated estradiol concentrations, whereas in another dog estradiol concentrations were within normal limits., Conclusion and Clinical Importance: Alopecia can occur after contact with a transdermal gel used as treatment for postmenopausal symptoms in women. Estradiol gel used by female owners therefore represents a possible cause for noninflammatory alopecia in dogs. Estradiol concentrations are not necessarily elevated in affected dogs., (© 2015 ESVD and ACVD.)

A 54-year-old woman was referred to the psychiatric clinic with complex somatic whole-body complaints. In absence of organic findings, the diagnosis of somatoform disorder (somatization disorder ICD 10 F45.0) was made. Additionally, due to the typical appearance and chronically elevated IGF-1 (somatomedin C) concentrations, the critical diagnosis of acromegaly was postulated, although no hypophyseal adenoma was detected. The patient was variously assessed and 16 medical and rehabilitation opinions were given with regard to invalidity, particularly by orthopaedic and neurologic specialists. The results varied, even diametrically opposed. However, somatoform disorders or acromegalic appearance and possible medical consequences were not considered sufficiently. The case report encourages experts to deal with complex psychosomatic complaints objectively and unemotionally in medical opinions.

Background: Physical exercise improves physical fitness of children and pupils may also benefit from sports with regard to cognitive competence. However, timetable and syllabus often give little scope so that alternatives such as combined lessons in English and sports may be suited to integrate the desire for exercise and leaning., Method: Parallel classes of a secondary school (form V; 39 pupils) were determined by random as control group (CG: age 10.5 ys, m 11, f 10) or intervention group (IG: age 10.7 ys, m 7, f 11). All pupils got regular physical education of 3 hours per week. In the IG one English lesson was relocated into the sports hall according to the "moving words" concept for one year. Both physical fitness (Munich fitness test) and concentration (d2-test) were assessed before and 3 times with intervals of 3 months. Moreover, 6-month marks were documented. All data were analyzed descriptively in addition to confirmative statistics (Repeated Measures ANOVA)., Results: Neither physical fitness nor concentration showed significant differences between the two groups. Both groups improved both criteria within one year, girls of the IG tended to work exacter with fewer mistakes (d2-Test), but dropped behind with regard to physical fitness. Otherwise, boys in the IG ameliorated rate of mistakes, tempo and exactness in the d2-test (p < 0.05) including a positive trend in physical fitness. Whereas English marks in the reports of the IG improved (0.4 versus 0.1), in both groups marks in sports did not change substantially., Conclusions: Particularly, boys benefit from the "moving-words" concept improving both their physical fitness as well as concentration. Why girls aged 10 to 11 years, on the contrary, do not benefit from the combined learning to the same degree is an interesting issue for further studies.

Hydrothermal carbonization allows rapid conversion of biomass into a carbon-rich, lignite-like product (hydrochar). It is assumed to have beneficial effects on soil properties and plant growth, but detailed studies are lacking, especially in the field. The objective of our study was to investigate the effect of hydrochar incorporated into arable soils on soil mineral nitrogen (N) content and sugar beet growth. In 2010-2011, a field and a pot trial were conducted. Hydrochars (field: 10 Mg ha; pot: equivalent to 30 Mg ha) processed from sugar beet pulp (HSP) and beer draff (HBD) were tested against an untreated control. As a second factor, mineral nitrogen (N) fertilizer level (field: 0, 50, 100, 150 kg N ha; pot: 0, 100, 200 mg N kg soil) was varied. In both trials, hydrochars reduced initial sugar beet growth, especially when hydrochar with a high C/N ratio (38, HSP) was combined with a low N fertilizer level; high N supply partly compensated for the reduced seedling growth. Without N fertilization, no extractable N was present at the end of the pot trial in the HSP treatment, whereas in HBD even more N was extracted than in the control. This suggests remineralization of previously immobilized N when hydrochar with a low C/N ratio was applied (16, HBD). In the field, beet yield was equal at the high N fertilizer level in HSP and at all N levels in HBD treatment. Our results suggest that hydrochar can decrease plant-available N due to N immobilization. Other potential causes for the observed early growth reduction need to be studied more in detail., (Copyright © by the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, Inc.)

In analogy to somatic medicine, modern psychiatry strives to measure the outcome of treatment and care. In order to warrant an effective therapy, this request is reasonable from the standpoint of both the therapist and the patient as well as hospitals or insurance companies. However, how can I measure friendliness, empathy or humanity, the "being available for somebody"? For sure, psychiatric DRGs, which connote efficacy based on periods of time, are by no means suitable. The present study analyses routine clinical data of an ergotherapeutic questionnaire, as an aid to estimating treatment quality. The naturalistic character of this data collection during daily routine may be an advantage to assessing the quality of results in psychiatry.
