The outlined suggestions may be used as a starting point to increase emergency preparedness and to inform outbreak response plans in the event of future infectious disease outbreaks.In Spring/Summer 2020, most individuals living in the United States experienced several months of social distancing and stay-at-home orders because of the coronavirus (COVID-19) pandemic. Clinicians, restaurant cooks, cashiers, transit operators, and other essential workers (EWs), however, continued to work outside the home during this time in order to keep others alive and maintain a functioning society. In the United States, EWs are often low-income persons of color who are more likely to face socioeconomic vulnerabilities, systemic racism, and health inequities. To assess the various impacts of COVID-19 on EWs, an online survey was distributed to a representative sample of individuals residing in six states during May/June 2020. The sample included 990 individuals who identified as EWs and 736 nonessential workers (NWs). We assessed differences between EW and NW respondents according to three categories related to health equity and social determinants of health (1) demographics (e.g. race/ethnicity); (2) COVID-19 exposure risk pathways (e.g. ability to social distance); and (3) COVID-19 risk perceptions (e.g. perceived risk of contracting COVID-19). EWs were more likely to be Black or Hispanic than NWs and also had lower incomes and education levels on average. Unsurprisingly, EWs were substantially more likely to report working outside the home and less likely to report social distancing and wearing masks indoors as compared to NWs. EWs also perceived a slightly greater risk of contracting COVID-19. These findings, which we discuss in the context of persistent structural inequalities, systemic racism, and health inequities within the United States, highlight ways in which COVID-19 exacerbates existing socioeconomic vulnerabilities faced by EWs.Development of gingival enlargement and periodontitis is described in a young dwarf mongoose. Repeated treatments resulted in gingival resection and histologic evaluation however gingival enlargement was ultimately responsive to extraction of associated teeth. In cases such as these, surgical extraction of teeth associated with severe recurrent gingival enlargement should be considered to avoid the stress and risk of repeated immobilizations.Circular RNA, typically generated from backsplicing reaction, is a class of single-stranded and covalently linked RNA. Although most circular RNAs are lowly expressed, some of them are able to accumulate to high levels and even exceed their cognate mRNAs due to their longer half-lives. Once produced in the nucleus, the majority of circular RNAs are exported to the cytoplasm for their proper functions or degradation. In this review, we will summarize the biogenesis and classification of circular RNAs and highlight the recent advances in our understanding of circular RNA nuclear export and degradation.
Population-based cancer screening can reduce cancer burden but was interrupted temporarily due to the COVID-19 pandemic. We estimated the long-term clinical impact of breast and colorectal cancer screening interruptions in Canada using a validated mathematical model.

We used the OncoSim breast and colorectal cancers microsimulation models to explore scenarios of primary screening stops for 3, 6, and 12 months followed by 6-24-month transition periods of reduced screening volumes. For breast cancer, we estimated changes in cancer incidence over time, additional advanced-stage cases diagnosed, and excess cancer deaths in 2020-2029. For colorectal cancer, we estimated changes in cancer incidence over time, undiagnosed advanced adenomas and colorectal cancers in 2020, and lifetime excess cancer incidence and deaths.

Our simulations projected a surge of cancer cases when screening resumes. For breast cancer screening, a three-month interruption could increase cases diagnosed at advanced stages (310 more) and cancer deaths (110 more) in 2020-2029. A six-month interruption could lead to 670 extra advanced cancers and 250 additional cancer deaths. For colorectal cancers, a six-month suspension of primary screening could increase cancer incidence by 2200 cases with 960 more cancer deaths over the lifetime. Longer interruptions, and reduced volumes when screening resumes, would further increase excess cancer deaths.

Interruptions in cancer screening will lead to additional cancer deaths, additional advanced cancers diagnosed, and a surge in demand for downstream resources when screening resumes. An effective strategy is needed to minimize potential harm to people who missed their screening.

The incidence of inborn errors of metabolism varies widely across countries. Very few studies have analyzed the incidence of these disorders in Mainland China. We aimed to estimate the overall and disease-specific incidences of inborn errors of metabolism in Chinese newborns and investigate the geographical distribution of these disorders.

A national cross-sectional survey was conducted to investigate newborn inborn errors of metabolism screening by tandem mass spectroscopy in Mainland China between 2016 and 2017. A total of 246 newborn screening centers were surveyed using a standardized questionnaire. We examined the cumulative and disease-specific incidences of inborn errors of metabolism in Mainland China as a whole and in different geographical locations.

Over 7 million newborns were screened and 2747 were diagnosed with inborn errors of metabolism, yielding an overall incidence of 38.69 per 100,000 births (95% confidence interval 37.27-40.17). The most common disorders were amino acid disorders (17.14 per 100,000 births, 95% confidence interval 16.21-18.13), followed by organic acid disorders (12.39 per 100,000 births, 95% confidence interval 11.60-13.24) and fatty acid oxidation disorders (9.16 per 100,000 births, 95% confidence interval 8.48-9.89). The overall and disease-specific incidence rates differed significantly across geographical locations (P < 0.001).

The overall incidence of inborn errors of metabolism in Chinese newborns is relatively high. It is urgent to establish the recommended uniform screening panel for inborn errors of metabolism to guide the national and regional tandem mass spectroscopy newborn screening programs.

Early diagnosis of biliary atresia is essential to improve long-term outcomes. Newborn screening with an infant stool color card allows early recognition of biliary atresia patients. Our aim was to develop and validate a mobile phone application (PopòApp) able to identify acholic stools.

An intuitive app was developed for iOS and Android smartphones. A learning machine process was used to generate an algorithm for stools color recognition based on the seven colors of the infant stool color card, which were considered as the gold standard. Consecutive images of stools were taken by the PopòApp, directly into the diapers of children aged ≤6 months. The PopòApp classified the photographs as "normal", "acholic" or "uncertain". To validate the PopòApp, four doctors independently classified all images, and only those for which all doctors agreed were included. The sensitivity, specificity, positive/negative predictive values, and accuracy of the PopòApp were evaluated.

Of 165 images collected, 160 were included in the study. All acholic stools were recognized by the PopòApp. The PopòApp sensitivity was 100% (95% CI93.9%-100%) with no false negatives, regardless of the brand of phone. The specificity was 99.0% (95% CI94.6%-99.9%). The accurancy of the PopòApp was 99.4% (95% CI96.6%-99.9%), with a positive predictive value of 98.4% (95% CI89.8%-99.8%).

The current study proved, in a large cohort, that the PopòApp is an accurate and easy tool for recognition of acholic stools. The mobile App may represent an effective strategy for the early referral of children with acholic stools, and potentially could improve the outcomes of biliary atresia.

Sparing of puboprostatic ligaments (PPLs) during radical prostatectomy was introduced as a technique to improve urinary continence. This study aims to study the effect of sparing of PPLs during laparoscopic radical prostatectomy in terms of continence during the first 3 months.

A total of 74 patients, diagnosed with clinically localized prostate cancer, were randomly assigned to two equal groups; PPLs division and sparing during LRP. Based on the number of daily used pads, both groups completed 3 months follow-up to assess continence recovery. The effects of age, preoperative total prostate-specific antigen (PSA) and clinical tumor stage on continence recovery were also studied. The study was registered and approved by the Ethics Committee of Alexandria University-Faculty of Medicine (Protocol No. 0201074).

Seventy-four patients were enrolled, with a mean age of 63.8 years. Baseline characteristics were comparable, except significantly higher mean PSA in the division group. Sixty patients were continent (0-1 pad/day) at 3 months follow-up. Continence was significantly better in the sparing than division group at 1 week after catheter removal (67.6% vs 40.5%,
 = 0.01), at 1 month (73% vs 45.9%,
 = 0.009) and 2 months (89.2% vs 51.4%,
 = 0.0001). At 3 months follow-up, there was no significant difference between both groups (83.3% vs 78.4% for sparing and division groups, respectively;
 0.28). Moreover, continence was significantly improved at 3 months compared to 1 week in both groups.

However, the roles and mechanisms of HOTAIR in acute myeloid leukaemia (AML) are still unclear and need to be investigated. In this study, we induced differentiation of four AML cell lines by all-trans retinoic acid (ATRA) and found HOTAIR was significantly upregulated in the process. Chromatin immunoprecipitation (ChIP) assays indicated that C/EBPβ upregulated HOTAIR during ATRA induced differentiation in HL-60 cells. By gain- and loss-of-function analysis, we then observed that HOTAIR expression was positively correlated with ATRA-induced differentiation and negatively regulated G1 phase arrest in HL-60 cells. In addition, we found that HOTAIR promoted ATRA-induced differentiation via the regulation of the cell cycle regulator p21 via miR-17-5p. Moreover, we detected the expression of HOTAIR in 84 de novo AML patients, HOTAIR was found significantly downregulated in the AML patients compared to the iron deficiency anaemia (IDA) control group, negatively correlated with the platelet level in M2 patients.
