Intern Med J 2021; 52:1409-1414. [PMID: 34028148 DOI: 10.1111/imj.15394] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 05/14/2021] [Accepted: 05/20/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND One metabolic equivalent (MET) is equal to resting oxygen consumption. The average value for one MET in humans is widely quoted as 3.5ml/kg/min. However this value was derived from a single male participant at the end of the nineteenth century and has become canonical. Several small studies have identified varied estimates of one MET from widely varying populations. The ability of a patient to complete 4 METS (or 14mls/kg/min) is considered an indicator of their fitness to proceed to surgery. AIMS The study aimed to define a typical value of one MET from a real-world patient population, as well as determine factors that influenced the value. METHODS A database of cardiopulmonary exercise tests (CPET) tests was interrogated to find total of 1847 adult patients who had undergone CPET testing in the previous 10 years. From this database, estimates of oxygen consumption (VO2 ) at rest and at the anaerobic threshold and a number of other variables were obtained. The influence of age, body mass index (BMI), sex and the use of beta blockers was tested. RESULTS The median resting VO2 at rest was 3.6ml/kg/min (IQR 3.0-4.2). Neither sex nor age greater than 65 years nor the use of beta blockers produced a significant difference in resting VO2 , while those with a BMI greater than 25 had a significantly lower VO2 at rest (3.4ml/kg/min vs 4.0ml/kg/min, p <0.001). CONCLUSIONS The estimate of 3.6ml/kg/min for resting VO2 presented here is consistent with the previous literature, despite this being the first large study of its kind. This estimate can be safely used for pre-operative risk stratification. This article is protected by copyright. All rights reserved.

Abstract
AIMS The adsorption behaviour and mechanisms of the surface modified activated carbon with bacteria was evaluated. METHODS AND RESULTS 16S rRNA was employed to identify the hydrocarbon-degrading bacteria. The bacteria was characterized by TEM and electron microscope. The surface modified activated carbon with bacteria was characterized by SEM. The adsorption behaviour was tested by static adsorption and dynamic adsorption. CONCLUSION The adsorption efficiency of the modified activated carbon was high when pH was weak acidic, and the adsorption capacity increased with the increase of temperature ranging from 20 to 35°C. The adsorption capacity peaked at 234·6 mg g-1 at 25°C, which was sixfold higher than that of activated carbon. The pseudo-first-order kinetic can more accurately assess Congo red adsorption on the two adsorbents. The adsorption of Congo red by bacteria surface modified activated carbon fitted well with the Langmuir's model. The adsorption process was endothermic, and the biological floccules were formed during the adsorption. The physical adsorption is the main driving force. SIGNIFICANCE AND IMPACT OF THE STUDY The results indicate that the bacteria surface-modified activated carbon can be used effectively as an adsorbent to eliminate Congo red from aqueous solutions.

Abstract
Objective: To investigate the clinical effects of autologous platelet rich plasma (PRP) gel in combination with vacuum sealing drainage (VSD) technology in repairing refractory wounds. Methods: From March 2011 to January 2015, 44 patients with refractory wounds meeting the inclusion criteria were recruited into VSD alone group, who were admitted to the Department of Burns and Plastic Surgery of the Yidu Central Hospital of Weifang and received intermittent VSD treatment. From February 2015 to September 2019, 43 patients with refractory wounds meeting the inclusion criteria were recruited into PRP+ VSD group, who were admitted to the same unit as above-mentioned and received PRP combined with intermittent VSD treatment. The retrospective cohort study was conducted. There were 24 males and 20 females with age of (37.5±2.2) years in VSD alone group, and there were 25 males and 18 females with age of (37.0±2.5) years in PRP+ VSD group. The wound exudate of patients in the two groups before and 7 and 14 d after the first treatment were collected for bacterial culture, and the positive rate of bacterial culture was calculated. The wound healing of patients in the two groups was observed on 7, 14, and 21 d after the first treatment, and the wound healing rate was calculated. The complete wound healing time of patients in the two groups was recorded. The degree of wound pain of patients in the two groups was evaluated by the Visual Analog Scale (VAS) before and 14 d after the first treatment. The scar hyperplasia of patients in the two groups was evaluated by the Vancouver Scar Scale (VSS) in 1 and 2 months after the wound healed completely. The occurrence of adverse reactions of patients in the two groups during the whole period of treatment was observed and the incidence of adverse reactions was calculated. Data were statistically analyzed with analysis of variance for repeated measurement, chi-square test, paired t test, and Bonferroni correction. Results: The positive rates of bacterial culture in wound exudate of patients in PRP+ VSD on 7 and 14 d after the first treatment were 37.2% (16/43) and 11.6% (5/43), which were significantly lower than 56.8% (25/44) and 29.5% (13/44) in VSD alone group, χ(2)=4.212, 4.255, P<0.05. The wound healing rates of patients in PRP+ VSD group on 7 and 14, and 21 d after the first treatment were respectively (58±14)%, (70±13)%, (89±12)%, which were significantly higher than (41±11)%, (60±11)%, (74±12)% in VSD alone group, t=6.323, 3.820, 5.751, P<0.01. The complete wound healing time of patients in PRP+ VSD group was (30±6) d, which was significantly shorter than (61±8) d in VSD alone group, t=20.890, P<0.05. The VAS score of patients in PRP+ VSD group was significantly lower than that in VSD alone group on 14 d after the first treatment (t=13.904, P<0.01). The VSS score of patients in PRP+ VSD group was significantly lower than that in VSD alone group in 1 and 2 months after the wound healed completely (t=3.307, 3.637, P<0.01). The incidence of adverse reactions of patients in PRP+ VSD group during the whole period of treatment was 7.0% (3/43), which was significantly lower than 22.7% (10/44) in VSD alone group, χ(2)=4.245, P<0.05. Conclusions: Autologous PRP gel combined with VSD technology in repairing refractory wounds not only has good bacteriostatic effect, but also can increase wound healing rate, shorten wound healing time, alleviate wound pain, reduce scar hyperplasia, with less adverse reaction, which is worthy of promotion.

Abstract
Proper formation of area identities of the cerebral cortex is crucial for cognitive functions and social behaviors of the brain. It remains largely unknown whether epigenetic mechanisms, including histone methylation, regulate cortical arealization. Here, we removed SETD2, the methyltransferase for histone 3 lysine-36 trimethylation (H3K36me3), in the developing dorsal forebrain in mice and showed that Setd2 is required for proper cortical arealization and the formation of cortico-thalamo-cortical circuits. Moreover, Setd2 conditional knockout mice exhibit defects in social interaction, motor learning, and spatial memory, reminiscent of patients with the Sotos-like syndrome bearing SETD2 mutations. SETD2 maintains the expression of clustered protocadherin (cPcdh) genes in an H3K36me3 methyltransferase-dependent manner. Aberrant cortical arealization was recapitulated in cPcdh heterozygous mice. Together, our study emphasizes epigenetic mechanisms underlying cortical arealization and pathogenesis of the Sotos-like syndrome.

Abstract
BACKGROUND Persistent skin manifestations, especially calcinoses, contribute to morbidity in children with juvenile dermatomyositis. OBJECTIVE To compare the course of skin and muscle involvement and document frequency of calcinosis in juvenile dermatomyositis. METHODS Prospective cohort study of 184 untreated children with juvenile dermatomyositis (July 1971 to May 2019) at a single children's hospital. RESULTS Disease Activity Scores (DASs) were persistently higher for skin versus muscle at all points; clinical inactivity (DAS ≤2) occurred earlier for muscle than skin. Among vascular features for DAS for skin, eyelid margin capillary dilatation was most frequent (54.3%) and persisted longest. Intravenous methylprednisolone reduced DAS for skin more than oral prednisone at 12 months (P = .04). Overall, 16.8% of patients (n = 31) had calcifications, with 4.9% at enrollment. Despite therapy, 25.0% of calcifications recurred and 22.6% failed to resolve; of the latter, 71.4% (n = 5) were present at enrollment. Children with persistent calcifications had longer duration of untreated disease than those whose calcifications resolved (mean 12.5 months) (P < .001). Hydroxychloroquine did not improve DAS for skin (P = .89). LIMITATIONS DAS does not quantify nailfold capillary dropout. CONCLUSIONS In juvenile dermatomyositis, skin disease presents with greater activity and is more recalcitrant to therapies than muscle disease. Early and aggressive treatment can limit the severity and persistence of calcifications identified later in the disease course.

Abstract
OBJECTIVE This study aimed to investigate the incidence and associated predictors of adverse pregnancy outcomes (APOs) among pregnant women infected with syphilis. DESIGN Cox regression analysis. SETTING China. POPULATION OR SAMPLE Pregnant women who were tested for and diagnosed with syphilis during the index pregnancy and delivered at a gestational age ≥28 weeks between 2016 and 2019. METHODS Data were extracted from China's Information System of Prevention of Mother-to-Child Transmission of Syphilis Management. Descriptive analysis provided profiles and pregnancy outcomes of maternal syphilis, as well as the incidence of APOs. Log-rank tests and Cox proportional hazard models were used to investigate factors influencing APOs in infected mothers with singleton births. MAIN OUTCOME MEASURES The incidence of APOs and the hazard ratios of associated predictors using Cox proportional hazard model. RESULTS Syphilis treatment data were available from 83.86% of diagnosed women. Including deliveries from the total study population, 13.33% experienced APOs. Cox regression indicated that APOs were more likely in women tested and diagnosed in the late trimester, at delivery or postpartum. Women who accepted non-standardised treatment and who received standardised treatment had less risk of APOs. CONCLUSIONS China has made huge progress over the last decades in the prevention of mother-to-child transmission of syphilis, but the incidence of APOs among pregnant women infected with syphilis remains high. It is essential to further strengthen access to early detection and standardised treatment of infected women to reduce the risk of APOs. TWEETABLE ABSTRACT Access to early detection and standardised treatment reduces the risk of APOs due to maternal syphilis.

Abstract
Long non-coding RNAs (lncRNAs) regulate transcription to control development and homeostasis in a variety of tissues and organs. However, their roles in the development of the cerebral cortex have not been well elucidated. Here, a bioinformatics pipeline was applied to delineate the dynamic expression and potential cis-regulating effects of mouse lncRNAs using transcriptome data from 8 embryonic time points and sub-regions of the developing cerebral cortex. We further characterized a sense lncRNA, SenZfp536, which is transcribed downstream of and partially overlaps with the protein-coding gene Zfp536. Both SenZfp536 and Zfp536 were predominantly expressed in the proliferative zone of the developing cortex. Zfp536 was cis-regulated by SenZfp536, which facilitates looping between the promoter of Zfp536 and the genomic region that transcribes SenZfp536. Surprisingly, knocking down or activating the expression of SenZfp536 increased or compromised the proliferation of cortical neural progenitor cells (NPCs), respectively. Finally, overexpressing Zfp536 in cortical NPCs reversed the enhanced proliferation of cortical NPCs caused by SenZfp536 knockdown. The study deepens our understanding of how lncRNAs regulate the propagation of cortical NPCs through cis-regulatory mechanisms.

Abstract
We present the experimental end-station TRIXS dedicated to time-resolved soft x-ray resonant inelastic x-ray scattering (RIXS) experiments on solid samples at the free-electron laser FLASH. Using monochromatized ultrashort femtosecond XUV/soft x-ray photon pulses in combination with a synchronized optical laser in a pump-probe scheme, the TRIXS setup allows measuring sub-picosecond time-resolved high-resolution RIXS spectra in the energy range from 35 eV to 210 eV, thus spanning the M-edge (M1 and M2,3) absorption resonances of 3d transition metals and N4,5-edges of rare earth elements. A Kirkpatrick-Baez refocusing mirror system at the first branch of the plane grating monochromator beamline (PG1) provides a focus of (6 × 6) μm2 (FWHM) at the sample. The RIXS spectrometer reaches an energy resolution of 35-160 meV over the entire spectral range. The optical laser system based on a chirped pulse optical parametric amplifier provides approximately 100 fs (FWHM) long photon pulses at the fundamental wavelength of 800 nm and a fluence of 120 mJ/cm2 at a sample for optical pump-XUV probe measurements. Furthermore, optical frequency conversion enables experiments at 400 nm or 267 nm with a fluence of 80 and 30 mJ/cm2, respectively. Some of the first (pump-probe) RIXS spectra measured with this setup are shown. The measured time resolution for time-resolved RIXS measurements has been characterized as 287 fs (FWHM) for the used energy resolution.

Abstract
Objective: To investigate the relationship between self-reported osteoarthritis (OA) and reproductive factors in the Women's Health Initiative (WHI). Method: We used multivariable logistic regression to study the association of self-reported OA and reproductive factors in the WHI Observational Study and Clinical Trial cohorts of 145 965 postmenopausal women, in a retrospective cross-sectional format. Results: In our cohort, we observed no clinically significant associations between reproductive factors and OA given small effect sizes. The following factors were associated with statistically significant increased likelihood of developing OA: younger age at menarche (p < 0.001), history of hysterectomy [adjusted odds ratio (aOR) 1.013, 95% confidence interval (CI) 1.004-1.022, p = 0.04 vs no hysterectomy], history of unilateral oophorectomy (aOR 1.015, 95% CI 1.004-1.026, p < 0.01 vs no oophorectomy), parity (aOR 1.017, 95% CI 1.009-1.026, p < 0.001), ever use of oral contraceptives (aOR 1.008, 95% CI 1.001-1.016, p < 0.01 vs never use), and current use of hormonal therapy (reference current users, aOR 0.951, 95% CI 0.943-0.959 for never users; aOR 0.981, 95% CI 0.972-0.989 for past users; global p < 0.001). Age at menopause, first birth, and pregnancy were not associated with OA. Among parous women, no clear pattern was observed with number of pregnancies, births, or duration of breastfeeding in relation to OA. Conclusion: Our study showed that reproductive factors did not have significant clinical associations with OA after controlling for confounders. This may be due to complex hormonal effects. Additional investigation is warranted in prospective cohort studies. The Women's Health Initiative is registered under ClinicalTrials.gov. Trial registration ID: NCT00000611.

Abstract
Background: Gestational diabetes mellitus (GDM) is a metabolic disease that can have long-term adverse effects on the cognitive function of mothers. In our study, we explored the changes in metabolic health and cognitive function in mice of middle- and old- age after exposure to GDM, and whether metformin therapy during pregnancy provided long-term benefits. Results: Mice with GDM demonstrated significant cognitive impairment in old age, which was associated with insulin resistance. Gestational metformin therapy was shown to increase insulin sensitivity and improve cognition. The ovarian aging rate was also accelerated in mice exposed to GDM during pregnancy, which may be related to fatty acid metabolism in the ovaries. Conclusion: Treatment with metformin during pregnancy was shown to improve fatty acid metabolism in ovarian tissues. Method: During pregnancy, mice were fed with a high-fat diet (GDM group) or a low-fat diet (Control group), and a third group received metformin while receiving a high-fat diet (Treatment group). At 12 months old, the mice completed an oral glucose tolerance test, insulin tolerance test, Morris water maze test, female sex hormones were measured, and metabolite profiles of tissue from the ovaries, hypothalamus, and pituitary glands were analysed using gas chromatography-mass spectrometry.

Abstract
This study of older visually impaired Nebraskans examined the effects of participation in peer support groups for visually impaired people and rehabilitation training. It found that those who participated in support groups and rehabilitation felt they were successful in coping with their visual loss, were satisfied with their level of activities, and generally had a positive outlook on life.

Simultaneous Nodal Superconductivity and Time-Reversal Symmetry Breaking in the Noncentrosymmetric Superconductor CaPtAs. PHYSICAL REVIEW LETTERS 2020; 124:207001.

Abstract
By employing a series of experimental techniques, we provide clear evidence that CaPtAs represents a rare example of a noncentrosymmetric superconductor which simultaneously exhibits nodes in the superconducting gap and broken time-reversal symmetry (TRS) in its superconducting state (below T_{c}≈1.5 K). Unlike in fully gapped superconductors, the magnetic penetration depth λ(T) does not saturate at low temperatures, but instead it shows a T^{2} dependence, characteristic of gap nodes. Both the superfluid density and the electronic specific heat are best described by a two-gap model comprising of a nodeless gap and a gap with nodes, rather than by single-band models. At the same time, zero-field muon-spin relaxation spectra exhibit increased relaxation rates below the onset of superconductivity, implying that TRS is broken in the superconducting state of CaPtAs, hence indicating its unconventional nature. Our observations suggest CaPtAs to be a new remarkable material that links two apparently disparate classes, that of TRS-breaking correlated magnetic superconductors with nodal gaps and the weakly correlated noncentrosymmetric superconductors with broken TRS, normally exhibiting only a fully gapped behavior.
