Primary care physicians have played a crucial role in delivery of vaccinations to the US population, including the elderly, between 2012-2017. These findings indicate primary care practices may be a crucial element of vaccine counseling and delivery in the upcoming COVID-19 recovery and immunization efforts in the United States.

Consequently, in biomedicine, mitochondria are considered as important targets for therapeutic treatments, and in evolutionary biology, they are considered as mediators of life-history tradeoffs. Surprisingly, data supporting such an assumption are lacking, at least partially due to the technical difficulties in accurately measuring the level of ROS produced by different subcellular compartments in intact cells. In this Commentary, we first review three potential reasons underlying the misassumption of mitochondrial dominance in the production of cellular ROS. We then introduce some other major sites/enzymes responsible for cellular ROS production. With the use of a recently developed cell-based assay, we further discuss the contribution of mitochondria to the total rate of ROS release in cell lines and primary cells of different species. In these cells, the contribution of mitochondria varies between cell types but mitochondria are never the main source of cellular ROS. This indicates that although mitochondria are one of the significant sources of cellular ROS, they are not necessarily the main contributor under normal conditions. Intriguingly, similar findings were also observed in cells under a variety of stressors, life-history strategies and pathological stages, in which the rates of cellular ROS production were significantly enhanced. Finally, we make recommendations for designing future studies. We hope this paper will encourage investigators to carefully consider non-mitochondrial sources of cellular ROS in their study systems or models.

Axial elongation in 73 eyes of 73 subjects who completed 3 years of orthokeratology (ortho-k) treatment was retrospectively reviewed. During their first year of ortho-k treatment (phase 1), they all demonstrated an axial elongation of 0.30 mm or greater. this website They were then divided into two groups orthokeratology and atropine (OKA) group (n=37) being treated with nightly 0.01% atropine in addition to ortho-k treatment for another 2 years and orthokeratology (OK) group (n=36) continued to be treated with ortho-k without atropine (phase 2). Axial elongation over time and between groups was compared.

Baseline biometrics was similar between the two groups in phase 1 (all p>0.05). The mean axial elongation was 0.47±0.15, 0.21±0.15, 0.23±0.13 mm for the OKA group and 0.41±0.09, 0.30±0.11, 0.20±0.13 mm for the OK group during the first, second and third year, respectively. The cumulative axial elongation over 3 years was 0.91±0.30 mm for the OKA group and 0.91±0.24 mm for the OK group. The overall AL change was not significantly different between the two groups (p=0.262). Baseline myopic refractive error had a significant impact on axial elongation over 3 years of treatment (p<0.001). None of baseline age (p=0.129), lens design (p=0.890) or treatment modality (p=0.579) had a significant impact on axial elongation.

For fast myopia progressors and poor responders of ortho-k, combining 0.01% nightly atropine did not significantly change the3-year axial elongation outcome as compared to ortho-k mono-therapy.

To determine the correspondence between GNAQ R183Q (c.548G＞A) mutation in abnormal scleral tissue of patients with Sturge-Weber syndrome (SWS) secondary glaucoma and explore the role of GNAQ R183Q in glaucoma pathogenesis.

Episcleral tissues were obtained from 8 patients SWS secondary glaucoma (n=5) and primary congenital glaucoma (PCG, n=3). Scleral tissues were obtained from 7 patients SWS secondary glaucoma (n=2), PCG (n=1) and juvenile open-angle glaucoma (n=4). GNAQ R183Q mutation was detected in scleral tissue by droplet digital PCR. Tissue sections from SWS were examined by immunohistochemistry to determine the expression of p-ERK.

The GNAQ R183Q mutation was present in 100% of the SWS abnormal sclera. Five cases were SWS patient-derived episcleral tissue, and the mutant allelic frequencies range from 6.9% to 12.5%. The other two were deep scleral tissues and the mutant frequencies were 1.5% and 5.3%. No mutations in GNAQ R183 codon were found in the sclera of PCG and juvenile open-angle glaucoman of ERK and JNK, providing new genetic evidence of pathogenesis of glaucoma in SWS, and the dysplasia of scleral tissue in anterior segment may be used as an early diagnostic method or treatment targets to prevent the development and progression of glaucoma in patients with SWS.

The effect of prenatal and postnatal exposure to fine particulate matter (PM

) on the development of allergic rhinitis (AR) is poorly understood. We further identified the vulnerable period for AR development to determine methods to decrease adverse effects.

We used a large population-based birth cohort of 140 911 singleton live infants in Taichung, Taiwan with a highly temporal-resolution satellite-based hybrid model to evaluate the effects of prenatal and early postnatal exposure on the onset of AR.

Among 140 911 children, 47 276 (33.55%) were cases of incident AR. The mean age of the children with AR at initial diagnosis was 2.97±1.78 years. We identified a significant association of AR with an interquartile range (IQR 17.98 µg/m

) increase in PM

from 30 gestational weeks to 52 weeks after birth. The exposure-response relationship revealed that AR had a significant positive association between PM

of 26-76 µg/m

(adjusted hazard ratios ranged from 1.00 to 1.05).

Our study provides evidence that both prenatal and postnatal exposures to PM

are associated with later development of AR.
