Summary Depression risk is associated with a late chronotype pattern often described as an ‘evening chronotype’. Fluctuations in mood over consecutive days have not yet been measured according to chronotype in in-patients with depression. A total of 30 in-patients with depression and 32 healthy controls matched for gender and age completed a chronotype questionnaire and twice-daily ratings on mood for 10 consecutive days (registered in the German Clinical Trials Register: DRKS00010215). The in-patients had Saturdays and Sundays as hospital-leave days. The relationship between chronotype and daily mood was mediated by the weekday–weekend schedule with higher levels of negative affect in the evening-chronotype patient subgroup at weekends. Results are discussed with respect to a probably advantageous standardised clinical setting with early morning routines, especially for patients with evening chronotypes.

Background: A key manifestation of Parkinson’s disease (PD) is visual impairment. Cognitive impairment has been found to overlap with convergence insufficiency (CI) in patients with PD and is associated with significantly greater near point convergence (NPC) distance. Difficulty in reading and diplopia were the most common symptoms of CI in PD. The prevalence of CI is greater among patients with PD. Therefore, this study aimed to assess the relationship between PD and CI. Methods: Studies that had included data on CI, NPC, or both were selected by searching PubMed/MEDLINE and clinicaltrails.gov, without any timeline or language limitation. The following terms were used in PubMed/MEDLINE search: ‘Clinical Trials’, ‘Parkinson’s Disease’, and ‘Convergence Insufficiency’. For clinical trials.gov database, the terms ‘Parkinson’s Disease’, ‘Convergence Insufficiency’, and ‘Completed Studies’ were used. Only those studies with control subjects were included. PubMed/MEDLINE search yielded 1,563 articles, but no article was found in the clinical trails.gov search. Twelve articles met the inclusion criteria, among which nine articles were selected as they had data on CI or NPC distance (cm), and PD.   Results: Overall, there were 1,563 articles; among them, 12 articles met the inclusion criteria. Nine articles were selected based on their data concerning CI or NPC distance (cm) and PD. Relative to the control group, the PD group had high CI. In addition, PD group showed increase in NPC distance than the control group. Conclusions: These data suggest that the patients with PD had an increased likelihood of developing CI visual symptoms, and increased NPC distance than healthy controls. These findings indicate that regular eye examination is very important for patients with PD.

To explore the relationship between negative affect, mind-wandering, rumination and obsessive-compulsive symptoms, 100 patients with obsessive-compulsive disorder and 100 healthy controls were assessed using the Obsessive-Compulsive Inventory, the Beck Anxiety Inventory, the Beck Depression Inventory, the Mind Wandering Scale and the Ruminative Response Scale. The results show that (i) patients diagnosed with obsessive-compulsive disorder displayed higher obsessive-compulsive symptoms, negative affect, mind-wandering and rumination compared with healthy controls; (ii) negative affect, mind-wandering and rumination were positively correlated with the severity of obsessive-compulsive symptoms; (iii) mind-wandering predicted the severity of obsessive-compulsive symptoms (both directly and indirectly); (iv) rumination and negative affect mediated the relationship between mind-wandering and obsessive-compulsive symptoms. The results preliminarily reveal the relationship between mind-wandering and psychopathological obsessive-compulsive symptoms, providing a reference for exploring novel psychological treatments for obsessive-compulsive disorder.

AbstractConsequences of a long stay in dog shelter have particular significance, because, since 1991, the Italian law (14/08/1991, n.281) prohibits euthanasia of dogs unless “they are seriously ill, incurable or proven dangerous”. Caught dogs are recovered for a quarantine period in the sanitary kennel, if they are not returned to the owner, they are moved to shelters until adoption or death. The aim of this work was to identify the relationship between dogs characteristics and their destiny in order to define useful predictors to better manage the stay of dogs in shelter. We analysed the records of all dogs recovered in a sanitary kennel from 2005 to 2010 and subsequently moved to shelters (n=771). Descriptive and inferential statistics were performed in order to investigate possible factors that might affect adoptability of sheltered dogs. The characteristics of dogs that spent more time in PVCS, before being transfer to the CR, were: large size, male gender and age between 11 months and 2 years (p ≤ 0,05). Male dogs spent more days in CR, as opposed to female (p ≤ 0,05). In our sample 76% dogs were adopted, 18% were still in the shelter, 4% died and 2% were euthanized. Female dogs were adopted more than males; young dogs more than elderly (over seven years); sizes medium and small more than large. It would be interesting use the data from this research and complete them with information regarding dogs behaviour, to better manage dogs during the stay in shelter and to improve their relocation.

Background: Combining optimized cognitive (Alzheimer's Disease Assessment Scale- Cognitive subscale, ADAS-Cog) and atrophy markers of Alzheimer's disease for tracking progression in clinical trials may provide greater sensitivity than currently used methods, which have yielded negative results in multiple recent trials. Furthermore, it is critical to clarify the relationship among the subcomponents yielded by cognitive and imaging testing, to address the symptomatic and anatomical variability of Alzheimer's disease. Method: Using latent variable analysis, we thoroughly investigated the relationship between cognitive impairment, as assessed on the ADAS-Cog, and cerebral atrophy. A biomarker was developed for Alzheimer's clinical trials that combines cognitive and atrophy markers. Results: Atrophy within specific brain regions was found to be closely related with impairment in cognitive domains of memory, language, and praxis. The proposed biomarker showed significantly better sensitivity in tracking progression of cognitive impairment than the ADAS-Cog in simulated trials and a real world problem. The biomarker also improved the selection of MCI patients (78.8±4.9% specificity at 80% sensitivity) that will evolve to Alzheimer's disease for clinical trials. Conclusion: The proposed biomarker provides a boost to the efficacy of clinical trials focused in the mild cognitive impairment (MCI) stage by significantly improving the sensitivity to detect treatment effects and improving the selection of MCI patients that will evolve to Alzheimer’s disease.

BACKGROUND The COVID-19 pandemic has challenged the in-person-based self-management approach (i.e., face-to-face or group approach) of type 2 diabetes (T2D). Older adults with T2D, including Asian Americans (AAs), have experienced worsening of diabetes control due to various reasons, including uncertainty of continuous access to essential diabetes medications, devices, education, limited health literacy, as well as constant anxiety and stress. Hybrid clinical trials that incorporate virtual elements into the in-person-based study could provide these vulnerable populations with accessible and timely interventions OBJECTIVE The primary aims of this pilot study are to determine (1) the effect of personalized behavioral nutrition (PBN) intervention on glycemic control, weight control, and metabolites profiles; and (2) the acceptability of PBN. to enhance glycemic control using personalized behavioral nutrition. METHODS Participants will be recruited with a web-based registry, advertisements in ethnic newspapers, and social network services popular among AAs. A total of 60 AAs, aged 65 years or older, who are descendants of Chinese, Korean, or South Asian, and have a diagnosis of T2D will be randomized into two groups: a PBN group (n=30) and a control group (n=30). A 4-week PBN intervention comprises three components: 1) digital self-monitoring; 2) personal nutrition change goals and recommendations; and 3) diabetes nutrition educations. All participants will complete digital self-monitoring on diet, physical activity, and blood glucose. In addition, all participants will access an interactive digital platform to track their self-monitoring data and communicate with the research team. The effectiveness and acceptability of implementing the intervention will be assessed. RESULTS Funding support and institutional review board approval for this study have been secured. Data collection started in August 2020 and is ongoing. CONCLUSIONS To our knowledge, this is the first study to determine the effectiveness and acceptability of PBN utilizing a metabolomics approach and digital-assisted intervention with hybrid RCT among older AAs. The findings of this pilot study will inform the development of a full-scale PBN protocol and hybrid clinical trials that can be adapted for people with T2D in the ongoing pandemic.

Abstract The relationship between nest entrance orientation and latitude among ground-nesting passerines was reviewed using published information. Data were collated for seven North American and European species. Pooling within-species comparisons, there was a clear trend from a preference for north-facing nests at lower latitudes to eastward- or southward-facing nests farther north. Orientations differed significantly in eight of 12 cases for which statistical comparison was possible, means differing in the expected direction in six of these cases. These results highlight how the influence of solar radiation on nest microclimate typically delineates preferred nest orientation in these species, i.e., at lower latitudes, the need for shade results in a preference for northward orientations; at mid latitudes, eastward orientations predominate, reflecting a probable balance between the benefits of warmth in the early morning and shade in the afternoon; while at high latitudes, nests may be oriented southward to gain warmth throughout the day.
