Allele purging dynamics depended on spatial environment, however the patterns of purging rates between the environments differed across distinct deleterious mutations. We also tested two of the mutant alleles, and demonstrate sexual selection increased the purging rate.PPP3CA encodes the catalytic subunit of calcineurin, a calcium-calmodulin-regulated serine-threonine phosphatase. Loss-of-function (LoF) variants in the catalytic domain have been associated with epilepsy, while gain-of-function (GoF) variants in the auto-inhibitory domain cause multiple congenital abnormalities. We herein report five new patients with de novo PPP3CA variants. Interestingly, the two frameshift variants in this study and the six truncating variants reported previously are all located within a 26-amino acid region in the regulatory domain (RD). Patients with a truncating variant had more severe earlier onset seizures compared to patients with a LoF missense variant, while autism spectrum disorder was a more frequent feature in the latter. Expression studies of a truncating variant showed apparent RNA expression from the mutant allele, but no detectable mutant protein. Our data suggest that PPP3CA truncating variants clustered in the RD, causing more severe early-onset refractory epilepsy and representing a type of variants distinct from LoF or GoF missense variants.
The COVID-19 pandemic is an ongoing stressor that may have detrimental effects on mental health. TDI-011536 in vitro Theoretical and empirical literature implies that individuals who are characterized by catastrophic appraisals of somatic cues, a tendency known as anxiety sensitivity, as well as by older subjective age, might be particularly vulnerable to depression and anxiety during the pandemic. Furthermore, subjective age might moderate the relations between anxiety sensitivity with depression and anxiety symptoms. Yet, research to date has not explored the contribution of both anxiety sensitivity and subjective age in explaining distress following stress in general, nor in light of the current COVID-19 pandemic.

Filling this gap, a convenience sample of 828 participants, (Mage = 43.98, SD = 14.06), filled questionnaires measuring background variables, COVID-19 related stressors, anxiety sensitivity, subjective age, and anxiety and depression symptoms during the pandemic.

Positive associations were found between anxiety sensitivity and subjective age, on the one hand, and anxiety and depression symptoms, on the other. Furthermore, subjective age moderated the associations between anxiety sensitivity with depression and anxiety symptoms. Although higher levels of anxiety sensitivity were related to depression and anxiety during the pandemic, these associations were stronger among participants with an older subjective age.

The findings are consistent with theories that view subjective age as an intra-individual construct involved in modulating important mental health outcomes in the context of coping with stress.

Loneliness and social isolation are emerging public health challenges for aging populations.

We followed N=11,302 US Health and Retirement Study (HRS) participants aged 50-95 from 2006-2014 to measure persistence of experiences of loneliness and exposure to social isolation. We tested associations of longitudinal loneliness and social isolation phenotypes with disability, morbidity, mortality, and biological aging through 2018.

During follow-up, 18% of older adults met criteria for loneliness, with 6% meeting criteria at two or more follow-up assessments. For social isolation, these fractions were 21% and 8%. HRS participants who experienced loneliness and were exposed to social isolation were at increased risk for disease, disability, and mortality. Those experiencing persistent loneliness were at a 57% increased hazard of mortality compared to those who never experienced loneliness. For social isolation, the increase was 28%. Effect-sizes were somewhat larger for counts of prevalent activity limitatios of loneliness may promote healthy aging.
Early HIV diagnosis allows combination antiretroviral therapy (cART) initiation in the first days of life following in utero (IU) infection. The impact of early cART initiation on infant viral reservoir size in the setting of high-frequency cART non-adherence is unknown.

Peripheral blood total HIV DNA from 164 early treated (day 0-21 of life) IU HIV-infected South African infants was measured using droplet digital PCR at birth and following suppressive cART. We evaluated the impact of cART initiation timing on HIV reservoir size and decay, and on the risk of subsequent plasma viraemia in cART-suppressed infants.

Baseline HIV DNA (median 2.8 log10 copies/million PBMC, range 0.7 - 4.8) did not correlate with age at cART initiation (0-21 days) but instead with maternal antenatal cART use. In 98 infants with plasma viral suppression on cART, HIV DNA half-life was 28 days. However, the probability of maintenance of plasma aviraemia was low (0.46 at 12 months) and not influenced by HIV DNA load. Unexpectedly, longer time to viral suppression was associated with protection against subsequent viral rebound.

With effective prophylaxis against mother-to-child transmission, cART initiation timing in the first 3 weeks of life is not critical to reservoir size.

This study retrospectively reviewed clinical records of BICU patients to investigate the utility of pressure mapping data in determining the incidence, predictors and associated costs of hospital-acquired pressure injuries. Of 122 patients, 57 (47%) were studied prior to implementation of pressure mapping and 65 (53%) were studied after implementation. The hospital-acquired pressure injury rate was 18% prior to implementation of pressure monitoring, which declined to 8% post-implementation (chi square p=0.10). Hospital acquired pressure injuries were less likely to be stage 3 or worse in the post-implementation cohort (p less then 0.0001). Upon multivariable-adjusted regression accounting for known predictors of hospital-acquired pressure injuries in burn patients, having had at least 12 hours of sustained pressure loading in one area significantly increased odds of developing a pressure injury in that area (odds ratio 1.3, 95%CI 1.0-1.5, p=0.04). Patients who developed hospital-acquired pressure injuries were significantly more likely to have had unsuccessful repositioning efforts in comparison to those who did not (p=0.02). Finally, implementation of pressure mapping resulted in significant cost savings - $6,750 (standard deviation $1008) for HAPI-related care prior to implementation, versus $3,800 (standard deviation $923) after implementation, p=0.008. In conclusion, the use of real-time pressure mapping decreased the morbidity and costs associated with hospital-acquired pressure injuries in BICU patients.Orchid gynostemium, the fused organ of the androecium and gynoecium, and ovule development are unique developmental processes. Two DROOPING LEAF/CRABS CLAW (DL/CRC) genes were identified from the Phalaenopsis orchid genome and functionally characterized, including PeDL1 and PeDL2. Phylogenetic analysis indicated that the most recent common ancestor of orchids contained the duplicated DL/CRC-like genes. The temporal and spatial expression analysis indicated PeDL genes are specifically expressed in the gynostemium and at the early stages of ovule development. Both PeDLs could partially complement an Arabidopsis crc-1 mutant. Virus-induced gene silencing (VIGS) of PeDL1 and PeDL2 affects the number of protuberant ovule initials differentiated from the placenta. Transient overexpression of PeDL1 in Phalaenopsis orchids caused abnormal development of ovule and stigmatic cavity of gynostemium. PeDL1, instead of PeDL2, could form a heterodimer with PeCIN8. Paralogous retention and subsequent divergence of the gene sequence of PeDL1 and PeDL2 in P. equestris might result in the differentiation of function and protein behaviors. These results reveal the ancestral duplicated DL/CRC-like genes in orchids play important roles in orchid reproductive organ innovation.
Primary hyperparathyroidism (PHPT) is associated with impaired bone quality and increased fracture risk. Reliable tools for the evaluation of bone quality parameters are not yet clinically available. Bone Strain Index (BSI) is a new metric for bone strength based on Finite Element Analysis from lumbar spine and femoral neck dual-energy x-ray absorptiometry (DXA) images.

To assess the lumbar spine (LS), femoral neck (FN), and total hip (TH) BSI in PHPT patients compared with controls and to investigate the association of BSI with vertebral fractures (VFs) in PHPT.

This case-control study enrolled 50 PHPT patients and 100 age- and sex-matched control subjects from an outpatient clinic. The main outcome measures were LS-BSI, FN-BSI, and TH-BSI.

FN bone mineral density (BMD) and one-third distal radius BMD were lower in the PHPT group than in controls (FN 0.633 ± 0.112 vs 0.666 ± 0.081, P = 0.042; radius 0.566 ± 0.07 vs 0.625 ± 0.06, P < 0.001). PHPT group has significant lower TBS score compared with controls (1.24 ± 0.09 vs 1.30 ± 0.10, P < 0.001). BSI was significantly higher at LS (2.28 ± 0.59 vs 2.02 ± 0.43, P = 0.009), FN (1.72 ± 0.41 vs 1.49 ± 0.35, P = 0.001), and TH (1.51 ± 0.33 vs 1.36 ± 0.25, P = 0.002) in PHPT. LS-BSI showed moderate accuracy for discriminating VFs (AUC 0.667; 95% CI, 0.513-0.820). LS-BSI ≥ 2.2 and was a statistically significant independent predictor of VFs, with an adjusted odds ratio ranging from 5.7 to 15.1.

BSI, a DXA-derived bone quality index, is impaired in PHPT and may help to identify PHPT subjects at high risk of fractures.

Specifically, literature suggests these groups have difficulties perceiving gestures that accompany speech. While our understanding of gesture perception in psychotic disorders is growing, gesture perception abnormalities and clues about potential causes and consequences among individuals meeting criteria for a clinical high-risk (CHR) syndrome is limited. Presently, 29 individuals with a CHR syndrome and 32 healthy controls completed an eye-tracking gesture perception paradigm. In this task, participants viewed an actor using abstract and literal gestures while presenting a story and eye gaze data (eg, fixation counts and total fixation time) was collected. Furthermore, relationships between fixation variables and both symptoms (positive, negative, anxiety, and depression) and measures of visual information processing (working memory and attention) were examined.
