Behavioral health issues, such as substance use, depression, and social isolation, are of grave concern during COVID-19, especially for vulnerable populations. One such population is US veterans, who have high rates of pre-existing behavioral health conditions and may thus be at-risk for poorer outcomes. The current study aimed to investigate substance use among US veterans during COVID-19 as a function of pre-existing depression, loneliness, and social support.

We investigated the relationship between pre-pandemic depression and substance use during COVID-19 using linear (alcohol) and logistic (cannabis) regression among a large sample of US veterans (N = 1230). We then tested if loneliness and social support moderated these effects.

Though there was a decrease in alcohol and cannabis use among the overall sample, veterans who screened for depression prior to the pandemic exhibited higher levels of substance use after the pandemic's onset. Loneliness compounded the effects of depression on rates of alcohol use. Social support was not protective for the effects of depression on either alcohol or cannabis use.

Veterans with pre-existing depression may be in need of attention for substance use behaviors. Interventions aimed at alleviating loneliness among veterans may be useful in mitigating alcohol use, but not cannabis use, amid COVID-19.

Our findings are among the first to report tangible behavioral health outcomes experienced by US veterans as a result of COVID-19. Results can help inform treatment efforts for veterans who are struggling with substance use during and post-pandemic.

To investigate the New South Wales (NSW) community's support for obesity prevention policies and concern for food marketing and promotion issues, and to determine any demographic differences or changes over time.

In 2013 (n=2474), 2016 (n=1602) and 2019 (n=1613) a sample of adults who were representative of the NSW population for age, gender, education and location was asked about support for policy initiatives that influence the food environment. Analysis identified the characteristics of those who supported policies and variation in support over time.

There were limited changes in support over time; however, support for many policies was strong and sustained. In 2019, support was highest for regulation of claims about nutrition (77.2%), and health warning labels (75.7%). Support for a ban on unhealthy food advertising that targets children (64.6%) had decreased since 2013. Women, older people and those who were aware that obesity was a risk factor for cancer were generally more likely to support policies. Parents were more likely than non-parents to be concerned about positioning unhealthy food at supermarket checkouts (OR 1.32) and unhealthy outdoor advertisements (OR 1.22). Concern increased in 2019 for unhealthy marketing on the internet (OR 1.21).

This study shows public support for policy options at moderate to high levels but not increasing in the six-year study period. Implications for public health These results form part of a package that, along with the well-established evidence, makes the case for policy action in Australia.

Mammalian cells are ideal platforms for identifying nanobodies targeting hard-to-display transmembrane proteins and nanobodies that function as modulators of cellular phenotypes. However, the introduction of a high-diversity nanobody library into mammalian cells is challenging. We have developed two novel methods for constructing a nanobody library in mammalian cells. Complementarity-determining region (CDR) random sequences were first incorporated into upstream and downstream dsDNAs by PCR. In the first method, named dsDNA-HR, upstream and downstream dsDNAs containing an identical overlapping sequence were co-transfected into cultured mammalian cells for intracellular homologous recombination that resulted in the formation of an intact nanobody library expression cassette. In the second method, named in vitro ligation, we generated full-length nanobody expression dsDNAs via ligation of restriction digested upstream and downstream dsDNAs. The obtained full-length dsDNAs were transfected into mammalian cells for nanobody library expression. Using both methods, we generated over a million unique nanobody sequences, as revealed by high-throughput sequencing. Single-cell sequencing was employed to resolve the diversity of the dsDNA-HR nanobody library. We also identified a small molecule, Nocodazole, which could enhance the efficacy of dsDNA-HR.Mutations in PRPH2, encoding peripherin-2, are associated with the development of a wide variety of inherited retinal diseases (IRDs). buy M3541 To determine the causality of the many PRPH2 variants that have been discovered over the last decades, we surveyed all published PRPH2 variants up to July 2020, describing 720 index patients that in total carried 245 unique variants. In addition, we identified seven novel PRPH2 variants in eight additional index patients. The pathogenicity of all variants was determined using the ACMG guidelines. With this, 107 variants were classified as pathogenic, 92 as likely pathogenic, one as benign, and two as likely benign. The remaining 50 variants were classified as variants of uncertain significance. Interestingly, of the in total 252 PRPH2 variants, more than half (n=137) were missense variants. All variants were uploaded into the Leiden Open source Variation and ClinVar databases. Our study underscores the need of experimental assays for variants of unknown significance to improve pathogenicity classification, which would allow to better understand genotype-phenotype correlations, and in the long-term, hopefully also support the development of therapeutic strategies for patients with PRPH2-associated IRD.

Patients whose parents had a history of Kawasaki disease (KD) often show a poor response to intravenous immunoglobulin (IVIG). There are very few reports describing the clinical characteristics and no reports on changes in C-reactive protein (CRP) level after IVIG administration in such cases.

A single-center cohort study including 950 patients hospitalized for KD and treated with IVIG was conducted. The patients were divided into two groups patients whose parents had a history of KD (PHK, N=16) and patients whose parents had no history of KD (NPHK, N=934). The clinical characteristics and responsiveness to IVIG were compared between the two groups.

The PHK group had higher CRP levels before administering IVIG than the NPHK group (P=0.0010). CRP levels after IVIG administration were higher in the PHK group than in the NPHK group (P=0.0094). The percentage of patients who received a second administration of IVIG on day 2 after the initial IVIG therapy was higher in the PHK group than in the NPHK group (P=0.0016). The percentage of patients who required plasma exchange therapy in the PHK group was significantly higher than that in the NPHK group (P=0.0010).

Patients in the PHK group had severe KD before IVIG administration, and these patients showed poor responsiveness to IVIG therapy.

The air indoors has profound health implications as it can expose us to pathogens, allergens and particulates either directly or via contaminated surfaces. There is, therefore, an upsurge in marketing of air decontamination technologies, but with no proper validation of their claims. We addressed the gap through the construction and use of a versatile room-sized (25m

) chamber to study airborne pathogen survival and inactivation.

Here, we report on the quantitative recovery and detection of an enveloped (Phi6) and a non-enveloped bacteriophage (MS2). The two phages, respectively, acted as surrogates for airborne human pathogenic enveloped (e.g., influenza, Ebola and coronavirus SARS-CoV-2) and non-enveloped (e.g., norovirus) viruses from indoor air deposited directly on the lawns of their respective host bacteria using a programmable slit-to-agar air sampler. Using this technique, two different devices based on HEPA filtration and UV light were tested for their ability to decontaminate indoor air. This safe, relatively simple and inexpensive procedure augments the use of phages as surrogates for the study of airborne human and animal pathogenic viruses.

This simple, safe and relatively inexpensive method of direct recovery and quantitative detection of viable airborne phage particles can greatly enhance their applicattion as surrogates for the study of vertebrate virus survival in indoor air and assessment of technologies for their decontamination.

The safe, economical and simple technique reported here can be applied widely to investigate the role of indoor air for virus survival and transmission and also to assess the potential of air decontaminating technologies.

This study sought to examine gender differences in patients with structural heart disease (SHD) referred for ablation of ventricular tachycardia (VT).

Female patients are often underrepresented in large studies. Significant differences in the clinical presentation, treatment, and prognosis of female patients have been described in previous studies.

We investigated 88 female patients with SHD undergoing VT ablation (mean age 59 years, 56% nonischemic cardiomyopathy, mean left ventricular ejection fraction 35%, 82% in electrical storm). A case-control study with 88 male patients was performed and the results regarding clinical and procedural characteristics, acute and long-term results of the two groups were compared. The female patients had more arrhythmogenic substrate, as they more commonly presented with electrical storm (p = .016) and had a higher number of inducible VT morphologies during the procedure (p = .018). Moreover, the female patients were less likely to have an optimized heart failure medial acute and long-term outcomes between the two genders were similar.Self-assembled chiroptical materials have attracted considerable attention due to their great applications in wide fields. During the chiral self-assembly, it remains unknown how achiral molecules can affect the assembly process and their final chiroptical performance. Herein, we report an achiral molecule directed chiral self-assembly via halogen bonds, exhibiting not only an unprecedented chiral fractal architecture but also significantly amplified circularly polarized luminescence (CPL). Two axially chiral emitters with halogen bond sites co-assemble with an achiral 1,4-diiodotetrafluorobenzene (F4 DIB) and well-ordered chiral fractal structures with asymmetry amplification are obtained. The enhancement of the dissymmetry factors of the assemblies was up to 0.051 and 0.011, which was approximately 100 folds than those of the corresponding molecules. It was found that both the design of the chiral emitter and the highly directional halogen bond played an important role in hierarchically chirality transfer from chiral emitters to the micrometer scale chiral fractal morphology and amplified dissymmetry factors.
