Evaluating the influence of action- and subject-specific factors on chimpanzee action copying
2021-02-01

The ability to imitate has been deemed crucial for the emergence of human culture. Although non-human animals also possess culture, the acquisition mechanisms underlying behavioural variation between populations in other species is still under debate. It is especially controversial whether great apes can spontaneously imitate. Action- and subject-specific factors have been suggested to influence the likelihood of an action to be imitated. However, few studies have jointly tested these hypotheses. Just one study to date has reported spontaneous imitation in chimpanzees (Persson et al . 2017 Primates 59 , 19–29), although important methodological limitations were not accounted for. Here, we present a study in which we (i) replicate the above-mentioned study addressing their limitations in an observational study of human–chimpanzee imitation; and (ii) aim to test the influence of action- and subject-specific factors on action copying in chimpanzees by providing human demonstrations of multiple actions to chimpanzees of varying rearing background. To properly address our second aim, we conducted a preparatory power analysis using simulated data. Contrary to Persson et al .'s study, we found extremely low rates of spontaneous chimpanzee imitation and we did not find enough cases of action matching to be able to apply our planned model with sufficient statistical power. We discuss possible factors explaining the lack of observed action matching in our experiments compared with previous studies.
Bispecific Antibodies in Prostate Cancer Therapy: Current Status and Perspectives
2021-02-01

Prostate carcinoma (PC) is the second most common cancer in men. When the disease becomes unresponsive to androgen deprivation therapy, the remaining treatment options are of limited benefit. Despite intense efforts, none of the T cell-based immunotherapeutic strategies that meanwhile have become a cornerstone for treatment of other malignancies is established in PC. This refers to immune checkpoint inhibition (CI), which generally reinforces T cell immunity as well as chimeric antigen receptor T (CAR-T) cells and bispecific antibodies (bsAbs) that stimulate the T cell receptor/CD3-complex and mobilize T cells in a targeted manner. In general, compared to CAR-T cells, bsAb would have the advantage of being an “off the shelf” reagent associated with less preparative effort, but at present, despite enormous efforts, neither CAR-T cells nor bsAbs are successful in solid tumors. Here, we focus on the various bispecific constructs that are presently in development for treatment of PC, and discuss underlying concepts and the state of clinical evaluation as well as future perspectives.
Use of local anesthetics with an epinephrine additive on fingers and penis – dogma and reality
2021-02-01

Summary Epinephrine supplements in local anesthetics are regularly used for surgery in areas with terminal vessels. According to the pharmaceutical guidelines, the use of epinephrine as an additive to local anesthetics is contraindicated for these areas. This review provides an overview of the current scientific data as well as new clinical developments in various fields. It also reviews the current legal situation. A literature research was carried out to survey the current status of relevant data. Written inquiries to several German institutions (Institute for Quality and Efficiency in Health Care, National Association of Statutory Health Insurance Physicians, Center for Clinical Studies Tübingen, Federal Institute for Drugs and Medical Devices) were made to determine the legal situation. No evidence was found in the literature for a causal relationship between the use of epinephrine as a vasoconstrictor and necrosis of the finger or penis. Studies and reviews show that the use of local anesthetics with epinephrine on the fingers or penis is a safe procedure with many clinical and economic advantages. In routine clinical practice, the WALANT method (Wide Awake Local Anesthesia No Tourniquet) as well as the increasing incidence of skin tumors in acral areas has led to a tendency towards increasing use. However, its use is still legally contraindicated, and the pharmaceutical companies show no interest in supporting a drug study. Further clinical trials – regardless of the strength of the evidence – would not change the current legal contraindication.
A case series of children and young people admitted to a tertiary care hospital in Germany with COVID-19
2021-02-01

Abstract Background While our knowledge about COVID-19 in adults has rapidly increased, data on the course of disease and outcome in children with different comorbidities is still limited. Methods Prospective, observational study at a tertiary care children’s hospital in southern Germany. Clinical and virology data from all paediatric patients admitted with SARS-CoV-2 infection at our hospital were prospectively assessed. Results Between March and November 2020, 14 patients were admitted with COVID-19. One patient was admitted a second time with COVID-19 6 months after initial disease. Among seven patients with severe underlying comorbidities, three developed multisystem inflammatory syndrome (MIS-C), two were admitted to the paediatric intensive care unit. One patient needed invasive ventilation. Another patient died shortly after discharge of COVID-19-related complications. Conclusions While COVID-19 generally causes mild disease in children, severe respiratory illness and MIS-C occur, in some cases with fatal outcome. Children with underlying diseases might be at special risk for severe disease.
The fit between dignity self‐construal and independent university norms: Effects on university belonging, well‐being, and academic success
2021-02-01

Abstract Universities struggle with students’ low well‐being and high dropout rates. High (compared to low) fit between students’ self‐construal and perceived university norms might help to prevent these problems. A strong dignity self‐construal (i.e., the understanding that one's worth is independent of others) is adaptive if university norms stress independence. The more a university norm is perceived as stressing independence, the better the fit for students with a strong (vs. weak) dignity self‐construal. Thus, if students with a strong dignity self‐construal perceive a university norm as stressing independence, they should develop a greater sense of belonging to the university and, in turn, experience higher well‐being, more motivation, and lower dropout intention. A longitudinal study with two measurement points conducted with students from 18 universities ( N = 719) provided support for these predictions. This underlines the relevance of the fit between student and (perceived) school characteristics for the higher education sector.
Local Recurrence Rates of Skin Tumors After Resection With Complete Circumferential Peripheral and Deep Margin Assessment—Identification of High-Risk Entities
2021-02-01

BACKGROUND The local recurrence rates of malignant skin tumors after micrographic controlled surgery using complete circumferential peripheral and deep margin assessment (CCPDMA) are reported to be low. However, in daily practice, tumor entities with a significantly higher recurrence rate are found. OBJECTIVE The aim of the investigation was to identify these high-risk tumors to develop approaches for risk stratification. PATIENTS AND METHODS We included different malignant tumors that were surgically treated and examined with CCPDMA using paraffin sections and H&amp;E staining. Re-excisions were performed until the tumor was completely removed. RESULTS Ninety-nine thousand three hundred seventy-two tumors were included in the study; the follow-up period was 4 years (median). Eight tumor entities were identified as high-risk entities, showing a significantly higher local recurrence rate of over 20%: desmoplastic squamous cell carcinoma, desmoplastic melanoma, Merkel cell carcinoma, microcystic adnexal carcinoma, pleomorphic sarcoma, liposarcoma as well as angiosarcoma, and extramammary Paget's disease. CONCLUSION Complete circumferential peripheral and deep margin assessment allows complete control of the resection margins and enables skin-sparing resections with low recurrence rates for basal cell carcinomas, nondesmoplastic squamous cell carcinomas, lentiginous melanomas, and dermatofibrosarcoma protuberans. However, other tumors show significantly higher recurrence rates and therefore need to be classified as high-risk tumors.
Prospective cohort study of mortality in very low birthweight infants in a single centre in the Eastern Cape province, South Africa
2021-02-01

Background Neonatal mortality is a major contributor worldwide to the number of deaths in children under 5 years of age. The primary objective of this study was to assess the overall mortality rate of babies with a birth weight equal or below 1500 g in a neonatal unit at a tertiary hospital in the Eastern Cape Province, South Africa. Furthermore, different maternal-related and infant-related factors for higher mortality were analysed. Methods This is a prospective cohort study which included infants admitted to the neonatal wards of the hospital within their first 24 hours of life and with a birth weight equal to or below 1500 g. Mothers who consented answered a questionnaire to identify factors for mortality. Results 173 very low birth weight (VLBW) infants were recruited in the neonatal department between November 2017 and December 2018, of whom 55 died (overall mortality rate 32.0%). Twenty-three of the 44 infants (53,5%) with a birth weight below 1000 g died during the admission. One hundred and sixty-one mothers completed the questionnaire and 45 of their babies died. Main factors associated with mortality were lower gestational age and lower birth weight. Need for ventilator support and sepsis were associated with higher mortality, as were maternal factors such as HIV infection and age below 20 years. Conclusion This prospective study looked at survival of VLBW babies in an underprivileged part of the Eastern Cape of South Africa. Compared with other public urban hospitals in the country, the survival rate remains unacceptably low. Further research is required to find the associated causes and appropriate ways to address these.
Do Social Cognition Deficits Recover with Abstinence in Alcohol‐Dependent Patients?
2021-02-01

Background Despite growing evidence of the presence and clinical relevance of deficits in social cognition in individuals with alcohol use disorder (AUD), less is known about the potential of “natural” recovery with abstinence in this neurocognitive domain. This study investigated the abstinence‐based recovery of neurocognitive social abilities in alcohol‐dependent patients (ADP) using a prospective longitudinal design with follow‐up assessment under controlled conditions of abstinence during alcohol dependence inpatient treatment. Methods Seventy‐seven participants (42 ADP and 35 healthy controls [HC]) performed social cognition testing, including facial emotion recognition, perspective taking, and affective responsiveness twice (baseline/T1 and follow‐up/T2) during comparable follow‐up periods. Assessment of social cognition in abstinent ADP was conducted at the beginning (T1; within the first 2 weeks) and at the end (T2; within the last 2 weeks) of long‐term (2 months) abstinence‐oriented alcohol dependence inpatient treatment. Only patients abstinent for &gt;14 days (last heavy drinking day &gt;21 days) at baseline (T1) and who remained abstinent at follow‐up (T2) were included. Results ADP, who on average were nearly 2 months abstinent at T1, showed poorer social cognition in all 3 areas (emotion recognition, perspective taking, and affective responsiveness) than HC. There was no difference between groups on the change in performance over time, and group differences (ADP vs. HC) remained significant at T2, indicating persistent social cognition deficits in ADP following controlled abstinence during inpatient treatment. Conclusions Our findings indicate no natural recovery of social cognition impairments in ADP during an intermediate to long‐term period of abstinence (2+ months), the usual active treatment phase. Research aimed at developing interventions that focus on the improvement of social cognition deficits (e.g., social cognition training) and determining whether they benefit short‐ and long‐term clinical outcomes in AUD seems warranted.
The less considered part: Contextualizing immaterial heritage from German colonial contexts in the restitution debate
2021-02-01

Abstract Since the publication of the “restitution report” by Felwine Sarr and Bénédicte Savoy in November 2018, the debate around the restitution of African artifacts inherited from German colonialism in German museums has become increasingly intense. While the restitution debate in Germany is generally focused on “material cultural heritage” and human remains, this reflection attempts to contextualize the “immaterial heritage” (museum collections inventory data, photographs, movies, sound recordings, and digital archive documents) from German colonialism and plead for its consideration in this debate. It claims that the first step of restitution consists of German ethnological museums being transparent about their possessions of artifacts from colonial contexts, which means providing all available information about museum collections from colonial contexts and making them easily accessible to the people from the former German colonies.
A Short Report on the Extent of Stone Handling Behavior Across Otter Species
2021-02-01

Animal stone-handling behavior (SH) has been recorded in detail only in primates, mainly across macaque species. The purpose(s) of SH are still unknown, yet various hypotheses have been suggested, including that it is a misdirected behavior when hungry and/or a play behavior that aids individuals' motor and stone tool-use development. SH has also been observed across both wild and captive otter species, but no overview report of the extent of this behavior across otter species has been published yet. To fill this gap in the literature, we contacted wild and captive otter researchers and keepers to enquire directly on SH in the species they work with. We accepted anecdotal reports in this first review of the behavior. Using the reports and anecdotes thus obtained, we compiled the first list of otter species that show SH. We found that most (10 out of 13) of currently known otter species practice SH. Therefore, similarly to macaques, SH is also common in otters and occurs in the majority of species. Future studies should focus on replicating these findings and further investigating the potential functions and selection pressures of SH in otters and other animal species.
Motivation-Enhancing Psychotherapy for Inpatients With Anorexia Nervosa (MANNA): A Randomized Controlled Pilot Study
2021-02-01

Patients with anorexia nervosa (AN) are frequently characterized by an unstable readiness to change and high ambivalence toward treatment. Enhancing readiness to behavioral change therefore plays an essential role for adherence to treatment especially for severely ill patients treated in inpatient settings. Therefore, a novel 10 week program for the individual psychotherapy sessions was designed using elements from motivational interviewing to be applied within the multidisciplinary inpatient treatment for patients with AN. In a randomized controlled pilot trial, N = 22 patients with AN received either the new intervention or treatment as usual in one of two recruiting university hospitals. Readiness to change, eating disorder pathology, therapeutic alliance as well as acceptance and feasibility of the new intervention were measured from patients and therapists in week 1, 5, and 10 of inpatient treatment. Results confirm acceptance and feasibility of the MANNA intervention as evaluated by patients as well as therapists. Patients receiving the new intervention completed their inpatient treatment significantly more often on regular terms than patients receiving treatment as usual. No differences between the groups could be found concerning therapeutic alliance during and at the end of treatment and readiness to change. Absolute numbers of BMI increase indicate a larger increase in the intervention group albeit not significant in this pilot study sample. Limitations of the study such as the small sample size as well as possible adaptions and advancements of the intervention that need to be examined in a larger clinical trial of efficacy are discussed. This phase II study is registered with the German Clinical Trials Register (DRKS) under the trial number DRKS00015639.
Incarnating water in Central Asia: Hydro-relations along a transboundary river
2021-02-01

Drawing on ethnographic fieldwork as well as collaborative events with artists and policy makers in Kyrgyzstan and Kazakhstan, I demonstrate how water concepts and forms of interaction are anchored in the particular water incarnations of springs, lakes, glaciers and big rivers. As main water arteries for the Aral Sea, the Naryn and Syr Darya Rivers are managed between shifting alliances of the farming interests, International Nongovernmental Organisation (INGO) bodies and national agencies of four riparian states. These Central Asian rivers have been subject to big dam-building programmes since the mid-Soviet period, while international companies now mine on the glaciers of the Naryn headwaters. I analyse socionatural water relations on a spectrum of three 'incarnations': first, river water as an exploitable resource; second, enspirited springs and lakes; and third, glaciers as indexes of human wrongdoing. While the multiplicity of water relations has been documented in many parts of the world, the concept of water incarnations highlights their topographical anchoring. This Central Asian case further shows how this anchoring can support claims of national entitlement. Finally, this paper argues that the situated heterogeneity of water relations can make it difficult to connect them to more sustainable water relationships in the region.
Separated and overlapping neural coding of face and body identity
2021-02-01

Abstract Recognising a person’s identity often relies on face and body information, and is tolerant to changes in low-level visual input (e.g. viewpoint changes). Previous studies have suggested that face identity is disentangled from low-level visual input in the anterior face-responsive regions. It remains unclear which regions disentangle body identity from variations in viewpoint, and whether face and body identity are encoded separately or combined into a coherent person identity representation. We trained participants to recognize three identities, and then recorded their brain activity using fMRI while they viewed face and body images of the three identities from different viewpoints. Participants’ task was to respond to either the stimulus identity or viewpoint. We found consistent decoding of body identity across viewpoint in the fusiform body area, right anterior temporal cortex, middle frontal gyrus and right insula. This finding demonstrates a similar function of fusiform and anterior temporal cortex for bodies as has previously been shown for faces, suggesting these regions may play a general role in extracting high-level identity information. Moreover, we could decode identity across neural activity evoked by faces and bodies in the early visual cortex, right inferior occipital cortex, right parahippocampal cortex and right superior parietal cortex, revealing a distributed network that encodes person identity abstractly. Lastly, identity decoding was consistently better when participants attended to identity, indicating that attention to identity enhances its neural representation. These results offer new insights into how the brain develops an abstract neural coding of person identity, shared by faces and bodies.
Abstract PR002: Global proteomic profiling of endometrial carcinomas identify prognostic markers
2021-02-01

Abstract While endometrial cancer (EC) has an overall good prognosis, some patients do poorly and there is room for refinement within current classification systems. Using the TCGA prognostic grouping of EC, our group developed the Proactive Molecular Risk Classifier for Endometrial Cancer (ProMisE), which reliably and reproducibly stratifies ECs into four prognostic groups: POLEmut, p53wt/NSMP, MMRd (mismatch repair deficient), and p53abn, with the best prognosis for POLEmut to worst prognosis for p53abn. In the current study, global proteomic analysis was performed using the clinical SP3-CTP workflow on archival tissues from 151 patients including 40 MMRd, 34 POLEmut, 34 p53abn and 43 p53wt/NSMP, with clinical follow up data. Included in the cohort were 11 replicate samples (different parts of the same tumor) to examine spatial heterogeneity in the proteomic profiles. Replicate samples were highly correlated to each other, with the exception of three POLEmut cases with very poor correlation in the proteome in different parts of the tumor. As POLEmut tumors have an exceedingly high mutation burden, it is not surprising that this translates to heterogeneity at the proteomic level. Disease specific survival was examined to determine prognostic significance within the whole cohort and within individual molecular subgroups. High TOMM34, PLTP or TSFM expression was correlated to poor disease specific survival in the whole cohort and independently prognostic when molecular subtype, grade and histotype are considered. High MGST, NCL or XPNPEP3 were associated with poor outcomes within the p53wt/NSMP group. POLD2 and ENAH were prognostic within the MMRd group. Within the p53abn group, ACADVL and BABAM1 were found to be prognostic, and GRB7 was found to be enriched in the p53abn group compared to other molecular subtypes. As the group with the worst prognosis, p53abn group could benefit from novel therapeutic avenues. ACADVL, BABAM1 and GRB7 all lie within pathways that are potentially targetable. Our proteomic analysis has identified prognostic markers that may be useful in further refining current molecular classification to help guide treatment decisions. Furthermore, new therapeutic interventions could be developed to target proteins and pathways identified by this proteomics screen. Citation Format: Dawn R.

Reexamining the Influence of Conditional Cash Transfers on Migration from a Gendered Lens: Comment
2021-02-01

In a recent article, "Reexamining the influence of conditional cash transfers on migration from a gendered lens," Hughes (2019) claimed that conditional cash transfers, CCT, limit the likelihood of migration by women, compensating them for giving up an attractive migration option. I question the analysis that lies behind this claim. I argue that in seeking to understand the likelihood of women migrating if they participate in a CCT program, issues of selectivity, endogeneity, and optimization cannot be set aside. In particular, it is not that receiving CCT curtails a migration option; it is that not contemplating migration encourages women to accept CCT. And if a household perspective is brought to bear, then a household's free choices weaken the appeal of migration to women. This reduction in appeal does not arise from an exogenously imposed curb but rather from endogenously determined preferences.
