Blue light has been previously reported to play a salient role in the treatment of seasonal affective disorder. The present study aimed to investigate whether blue light had antidepressant effect on light-deprivation-induced depression model, and the underlying visual neural mechanism. Blue light mitigated depression-like behaviors induced by light deprivation as measured by elevated sucrose preference and reduced immobility time. Blue light enhanced melanopsin expression and light responses in the retina. We also found the upregulation of serotonin and brain derived neurotrophic factor expression in the c-fos-positive areas of rats treated with blue light compared with those maintained in darkness. The species gap between nocturnal albino (Sprague-Dawley rat) and diurnal pigmented animals (human) might have influenced extrapolating data to humans. Blue light has antidepressant effect on light-deprived Sprague-Dawley rats, which might be related to activating the serotonergic system and neurotrophic activity via the retinoraphe and retinoamygdala pathways. Blue light is the effective component of light therapy for treatment of depression.
We aimed to determine whether Plasmodium falciparum (Pf) infection affects age of Kaposi sarcoma-associated herpesvirus (KSHV) seroconversion in Kenyan children.

Kenyan children (n=144) enrolled at age one month, from two sites with different levels of malaria transmission (stable/high malaria vs. unstable/low malaria transmission) were followed through 24 months. check details Plasma was tested for KSHV antibodies using enzyme-linked immunosorbent assay (ELISA) (K8.1 and LANA) and a multiplex bead-based assay (K8.1, K10.5, ORF38, ORF50, and LANA) and whole blood tested for Pf DNA using quantitative-PCR. Cox proportional hazards models were used to assess associations between Pf DNA detection, malaria annualized rate (Pf detections/person-years), and enrollment site (malaria-high vs malaria-low) with time to KSHV seroconversion.

KSHV seroprevalence was 63% by 2 years of age when assessed by multiplex assay. Children with Pf were at increased hazards of earlier KSHV seroconversion and among children with malaria, the hazard of becoming KSHV seropositive increased significantly with increasing malaria annualized rate. Children from the malaria-high transmission region had no significant difference in hazards of KSHV seroconversion at 12 months but were more likely to become KSHV seropositive by 24 months of age.

Malaria exposure increases the risk for KSHV seroconversion early in life.

To evaluate whether the prevalence of health problems in cohabiting partners of people with dementia differs between the year before and the year after three transitions the diagnosis of dementia, institutionalization and the death of the person with dementia.

Individuals with dementia and their partners were identified on the basis of data in the electronic health records (EHRs) of 451 Dutch general practices. EHRs were also the data source on their health problems, which were linked to the Dutch population registry and health administration data with demographic characteristics, date of institutionalization and date of death. Differences in the prevalence of sixteen groups of health problems and of specific health problems in partners during the year before and the year after the three transitions were examined using generalized estimating equation (GEE).

1110 partners of persons with dementia were identified. Problems related to the illness and/or loss of the person with dementia, were significantly more prevalent in the year after the dementia diagnosis (32% vs 17%) and in the year after the death of the person with dementia (59% vs 41%) than in the years before. Unspecified health problems were more prevalent in the year after the diagnosis than in the year before (30% vs 22%). After institutionalization, an increase was found in digestive problems and urological problems (30% vs 18% and 24% vs 17%).

Transitions during the dementia care trajectory, namely the diagnosis, institutionalization and death of the person with dementia, significantly impact the cohabiting partner's health.

Stressful life events contribute to insomnia, psychosocial functioning, and illness. Though individuals with a history of insomnia may be especially vulnerable during stressful life events, risk may be mitigated by prior intervention. This study evaluated the effect of prior digital cognitive-behavioral therapy for insomnia (dCBT-I) versus sleep education on health resilience during the COVID-19 pandemic.

COVID impact, insomnia, general- and COVID-related stress, depression, and global health were assessed in April 2020 in adults with a history of insomnia who completed a randomized controlled trial of dCBT-I (n = 102) versus sleep education control (n = 106) in 2016-2017. Regression analyses were used to evaluate the effect of intervention conditions on subsequent stress and health during the pandemic.

Insomnia symptoms were significantly associated with COVID-19 related disruptions, and those who previously received dCBT-I reported less insomnia symptoms, less general stress and COVID-related cognitive intrusions, less depression, and better global health than those who received sleep education. Moreover, the odds for resurgent insomnia was 51% lower in the dCBT-I versus control condition. Similarly, odds of moderate to severe depression during COVID-19 was 57% lower in the dCBT-I condition.

Those who received dCBT-I had increased health resilience during the COVID-19 pandemic in adults with a history of insomnia and ongoing mild to moderate mental health symptoms. These data provide evidence that dCBT-I is a powerful tool to promote mental and physical health during stressors, including the COVID-19 pandemic.

NCT02988375.The origin and deep history of retroviruses remain mysterious and contentious, largely because the diversity of retroviruses is incompletely understood. Here, we report the discovery of lokiretroviruses, a novel major lineage of retroviruses, within the genomes of a wide range of vertebrates (at least 137 species), including lampreys, ray-finned fishes, lobe-finned fishes, amphibians, and reptiles. Lokiretroviruses share a similar genome architecture with known retroviruses, but display some unique features. Interestingly, lokiretrovirus Env proteins share detectable similarity with fusion glycoproteins of viruses within the Mononegavirales order, blurring the boundary between retroviruses and negative sense single-stranded RNA viruses. Phylogenetic analyses based on reverse transcriptase demonstrate that lokiretroviruses are sister to all the retroviruses sampled to date, providing a crucial nexus for studying the deep history of retroviruses. Comparing congruence between host and virus phylogenies suggests lokiretroviruses mainly underwent cross-species transmission.
