The Risk of Vitamin D Deficiency, Osteoporosis, and Fractures in Acute Pancreatitis

Objectives A few past studies have found increased utilization of 25-hydroxyvitamin D and prevalence of osteoporosis in acute pancreatitis (AP). Our aim was to obtain a survey of bone diseases after a sentinel episode of AP. Methods A database (Explorys), an aggregate of electronic health record from 26 integrated United States healthcare systems, was queried. A cohort of patients with a Systematized Nomenclature of Medicine—Clinical Terms diagnosis of AP between 2014 and 2019, after excluding patients with selected medical conditions and medications that are associated with poor bone health, was identified. The prevalence of new diagnoses of vitamin D deficiency (VDD), osteoporosis, and fractures in the study cohort was evaluated. Age-, race-, and sex-based distributions and risk factors were determined through univariate and multivariate analyses. Results Of the 36,087,380 individuals in the database, we identified 256,580 (0.71%) with AP. In multivariate analysis, patients with AP were more likely to develop VDD (odds ratio [OR], 1.25; 95% confidence interval [CI], 1.24–1.26; P < 0.0001), osteoporosis (OR, 1.89; CI, 1.81–1.85; P < 0.0001), and fractures (OR, 1.58; 95% CI, 1.57–1.59; P < 0.0001). Conclusions Acute pancreatitis was associated with increased risk of VDD, osteoporosis, and fractures.
One-stop strategy for treatment of atrial fibrillation: feasibility and safety of combining catheter ablation and left atrial appendage closure in a single procedure

Abstract Background Catheter ablation is effective in restoring sinus rhythm and left atrial appendage closure (LAAC) is increasingly used for stroke prevention in patients with atrial fibrillation (AF). We aimed to observe the feasibility and safety of performing AF ablation and LAAC in a single (one-stop) procedure. Methods Consecutive AF patients who underwent the combined procedure of AF ablation and LAAC with WATCHMAN device between March 2017 and September 2018 were prospectively enrolled. Baseline and intra-procedural parameters were evaluated. Three-month and subsequent 1-year follow-up were performed in all and earlier-enrolled subjects, respectively. Results A total of 178 AF patients (94 males, 68.9 ± 8.1 years) underwent the one-stop procedure with CHA2DS2-VASc score 3.3 ± 1.5 and HAS-BLED score 1.6 ± 1.0, respectively. Pulmonary vein isolation was achieved in all patients while additional linear ablation was applied if the operator deemed necessary, yielding immediate ablation success rate of 98.9% (176/178). In the subsequent LAAC, satisfactory seal (residual leak <5 mm) was achieved in all patients. One stroke and four cardiac perforations occurred peri-operatively. At 3-month follow-up, sinus rhythm and satisfactory seal were maintained in 153/178 (86.0%) and 178/178 (100%) patients, respectively. One stroke and one delayed cardiac tamponade occurred, while no device-related thrombus or device migration was observed. During the 1-year follow-up for the earlier enrolled subjects, 52/72 (72.2%) of the patients maintained sinus rhythm. There was no stroke or systemic embolism observed. Conclusion Combining catheter ablation and LAAC in a single procedure can be successfully and safely performed in non-valvular AF patients of Chinese population.
A Mixed-Methods Study on Patient Safety Insights of New Graduate Registered Nurses.

BACKGROUND New graduate nurses transition with limited experience, and with anxiety and stress. They present an increased risk of contributing to preventable errors or adverse events. PURPOSE The purpose was to develop an understanding of new graduate registered nurses' (RNs) patient safety knowledge and actions within the first year of registration. METHODS The longitudinal mixed-methods study was conducted using a questionnaire delivered at 3 time points (n = 68). Qualitative data were collected by semistructured interviews (n = 11). RESULTS Self-reported knowledge of medical error decreased over the 3 time points. Themes emerging from qualitative data include patient safety and insights, time management, making a mistake, experiential learning, and transition. CONCLUSIONS Medical errors and time management persist during transition to the RN role. New graduates reported moderate knowledge of safety and quality issues; however, questioning their own abilities overshadowed growth in their involvement in patient safety.
Effect of plant lectins on larval development of the legume pod borer, Maruca vitrata

The legume pod‐borer Maruca vitrata (Fabricius), [Lepidoptera: Pyralidae] is a major constraint restricting increased cowpea production in tropical Africa and Asia. Since lectins are known to have insecticidal properties against several pests, a survey was undertaken to screen for the effects of 25 lectins from 15 plant families on the development of Maruca pod borer (MPB) larvae. The list included 8 galactose/N‐acetylgalactosamine‐, 7 mannose‐, 5 complex glycan‐, 2 sialic acid‐ and 3, N‐acetylglucosamine‐specific lectins. Feeding bioassays using artificial diet were carried out at 2% (w/w) topical levels. Although a total of 16 lectins had detrimental effects pertaining either to larval survival, weight, feeding inhibition, pupation, adult emergence and/or fecundity, only the Listera ovata agglutinin (LOA) (Orchidaceae) and Galanthus nivalis (Amaryllidaceae) agglutinin were effective against MPB larvae for all six parameters examined. Larval mortality and feeding inhibition caused by the most active lectin (LOA) was above 60%.
Turning the body into a clock: Accurate timing is facilitated by simple stereotyped interactions with the environment

Significance Humans rely on their inner sense of time to judge the duration of events or decide when to initiate actions. Still, they also often use movements to improve their timing accuracy. In both humans and animals, it is unclear whether accurate timing relies on disembodied internal representations or is externalized in motor routines. We investigated this issue in rats performing a timing task while running on a motorized treadmill. Our setup allowed us to create conditions that either favored or limited the usage of motor routines. We found that timing accuracy was improved when the environment afforded cues that rats can incorporate into motor routines. Timing, at least in animals, may thus be fundamentally embodied and situated. How animals adapt their behavior according to regular time intervals between events is not well understood, especially when intervals last several seconds. One possibility is that animals use disembodied internal neuronal representations of time to decide when to initiate a given action at the end of an interval. However, animals rarely remain immobile during time intervals but tend to perform stereotyped behaviors, raising the possibility that motor routines improve timing accuracy. To test this possibility, we used a task in which rats, freely moving on a motorized treadmill, could obtain a reward if they approached it after a fixed interval. Most animals took advantage of the treadmill length and its moving direction to develop, by trial-and-error, the same motor routine whose execution resulted in the precise timing of their reward approaches. Noticeably, when proficient animals did not follow this routine, their temporal accuracy decreased. Then, naïve animals were trained in modified versions of the task designed to prevent the development of this routine. Compared to rats trained in the first protocol, these animals didn’t reach a comparable level of timing accuracy. Altogether, our results indicate that timing accuracy in rats is improved when the environment affords cues that animals can incorporate into motor routines.
The pandemic of 1918 and the heart disease epidemic in middle-aged men and women in the United States

ABSTRACT Members of birth cohorts who were alive in 1918 and survived the influenza pandemic were likely to have been “primed” for heart disease in later life. We examine the hypothesis that the twentieth-century heart disease epidemic was a cohort effect reflecting the changing susceptibility composition of the population. We estimated heart disease death rates by single years of age for cohorts born in 1860–1949. We prepared age-specific rates for calendar years 1900–2016, as well as age-standardized cohort and calendar year rates. Males born in 1880–1919 contributed 90 per cent to 100 per cent of all heart disease deaths among males aged 40–64 from 1940 to 1959, when the heart disease epidemic was at its peak. There was no heart disease epidemic among females aged 40–64. Death from heart disease in females tends to occur at older ages. Cigarette smoking, unemployment, and other factors may have played a role in the heart disease epidemic in men and would have interacted with injury from influenza, but our results suggest that having been alive at the time of the 1918 influenza pandemic probably played an important role.
COVID-19 and lung cancer: risks, mechanisms and treatment interactions

Cases of the 2019 novel coronavirus also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continue to rise worldwide. To date, there is no effective treatment. Clinical management is largely symptomatic, with organ support in intensive care for critically ill patients. The first phase I trial to test the efficacy of a vaccine has recently begun, but in the meantime there is an urgent need to decrease the morbidity and mortality of severe cases. It is known that patients with cancer are more susceptible to infection than individuals without cancer because of their systemic immunosuppressive state caused by the malignancy and anticancer treatments. Therefore, these patients might be at increased risk of pulmonary complications from COVID-19. The SARS-CoV-2 could in some case induce excessive and aberrant non-effective host immune responses that are associated with potentially fatal severe lung injury and patients can develop acute respiratory distress syndrome (ARDS). Cytokine release syndrome and viral ARDS result from uncontrolled severe acute inflammation. Acute lung injury results from inflammatory monocyte and macrophage activation in the pulmonary luminal epithelium which lead to a release of proinflammatory cytokines including interleukin (IL)-6, IL-1 and tumor necrosis factor-α. These cytokines play a crucial role in immune-related pneumonitis, and could represent a promising target when the infiltration is T cell predominant or there are indirect signs of high IL-6-related inflammation, such as elevated C-reactive protein. A monoclonal anti-IL-6 receptor antibody, tocilizumab has been administered in a number of cases in China and Italy. Positive clinical and radiological outcomes have been reported. These early findings have led to an ongoing randomized controlled clinical trial in China and Italy. While data from those trials are eagerly awaited, patients’ management will continue to rely for the vast majority on local guidelines. Among many other aspects, this crisis has proven that different specialists must join forces to deliver the best possible care to patients.
Nissen fundoplication in Cornelia de Lange syndrome spectrum: Who are the potential candidates?

Cornelia de Lange spectrum (CdLSp) is a rare genetic condition characterized by intellectual disability, facial dysmorphisms, major malformations, growth impairment, and development delay. Approximately 80% of CdLSp patients have gastroesophageal reflux disease (GERD) with a varied clinical presentation. The aim of this study is to define potential clinical/genetic risk factors based on the clinical phenotype description of CdLSp patients with severe GERD who underwent surgical treatment. We retrospectively collected data from 23 CdLSp patients, 13 females and 10 males. Mean age of the patients undergoing surgical treatment was of 4 years. 21/23 (91%) had a molecular characterization, of which 21/21 (100%) had a NIPBL gene mutation, while 2/23 (9%) did not have a genetical characterization, only a clinical diagnosis. Most of our patients presented a moderate–severe severity score (21/23, 91%) with limb malformations evidenced in 10/23 (44%) of our patients and a moderate–severe intellectual disability in 20/23 (87%). Therefore, CdLSp patients harboring NIPBL variants, upper limb malformations and severe psychomotor delay are more likely to suffer from severe GERD, not responsive to proton pump inhibitors treatment. These features should be considered as clinical markers for potentially severe GERD that might require surgical treatment.
The Dreem Headband compared to polysomnography for electroencephalographic signal acquisition and sleep staging

Abstract Study Objectives The development of ambulatory technologies capable of monitoring brain activity during sleep longitudinally is critical for advancing sleep science. The aim of this study was to assess the signal acquisition and the performance of the automatic sleep staging algorithms of a reduced-montage dry-electroencephalographic (EEG) device (Dreem headband, DH) compared to the gold-standard polysomnography (PSG) scored by five sleep experts. Methods A total of 25 subjects who completed an overnight sleep study at a sleep center while wearing both a PSG and the DH simultaneously have been included in the analysis. We assessed (1) similarity of measured EEG brain waves between the DH and the PSG; (2) the heart rate, breathing frequency, and respiration rate variability (RRV) agreement between the DH and the PSG; and (3) the performance of the DH’s automatic sleep staging according to American Academy of Sleep Medicine guidelines versus PSG sleep experts manual scoring. Results The mean percentage error between the EEG signals acquired by the DH and those from the PSG for the monitoring of α was 15 ± 3.5%, 16 ± 4.3% for β, 16 ± 6.1% for λ, and 10 ± 1.4% for θ frequencies during sleep. The mean absolute error for heart rate, breathing frequency, and RRV was 1.2 ± 0.5 bpm, 0.3 ± 0.2 cpm, and 3.2 ± 0.6%, respectively. Automatic sleep staging reached an overall accuracy of 83.5 ± 6.4% (F1 score: 83.8 ± 6.3) for the DH to be compared with an average of 86.4 ± 8.0% (F1 score: 86.3 ± 7.4) for the 5 sleep experts. Conclusions These results demonstrate the capacity of the DH to both monitor sleep-related physiological signals and process them accurately into sleep stages. This device paves the way for, large-scale, longitudinal sleep studies. Clinical Trial Registration NCT03725943.
Clinical spectrum and prognostic value of TP53 mutations in circulating tumor DNA from breast cancer patients in China

TP53 mutations are common in breast cancer. There is currently no large‐scale cohort study to investigate the TP53 landscape in breast cancer patients from China. The predictive value of TP53 mutations for the efficacy of human epidermal growth factor receptor 2 (HER2)‐targeted therapy in breast cancer remains controversial. In the present study, we aimed to analyze the clinical spectrum and prognostic value of TP53 mutations in circulating tumor DNA (ctDNA) from breast cancer patients in China.
Molecular Phylogeny of a tick, Ixodes granulatus (Acari: Ixodidae) based on cytochrome oxidase subunit I (COI) marker

Identification of a local species of tick, Ixodes granulatus from the family Ixodidae is essential because it has potential to be vector for spotted fever group (SFG) rickettsia and tick thypus. The aim of this study is to portray the relationships among several populations of I. granulatus collected from different species of animal hosts and localities in Peninsular Malaysia. Polymerase Chain Reaction was conducted by amplifying mitochondrial DNA marker, namely cytochrome oxidase subunit I (COI) sequences from 15 individual ticks that attached to five different hosts caught from three different localities. Confirmation of the species identity was accomplished using BLAST program. Neighbor-joining (NJ) and Maximum Parsimony (MP) tree based on COI sequences were constructed by using PAUP 4.0b10 to identify the relationship among species. The result of this study showed a high genetic heterogeneity between I. granulatus and other species of the same genus (7.2-23.7%). Furthermore, a low intraspecific variat.
NSM00158 Specifically Disrupts the CtBP2-p300 Interaction to Reverse CtBP2-Mediated Transrepression and Prevent the Occurrence of Nonunion

Carboxyl-terminal binding proteins (CtBPs) are transcription regulators that control gene expression in multiple cellular processes. Our recent findings indicated that overexpression of CtBP2 caused the repression of multiple bone development and differentiation genes, resulting in atrophic nonunion. Therefore, disrupting the CtBP2-associated transcriptional complex with small molecules may be an effective strategy to prevent nonunion. In the present study, we developed an in vitro screening system in yeast cells to identify small molecules capable of disrupting the CtBP2-p300 interaction. Herein, we focus our studies on revealing the in vitro and in vivo effects of a small molecule NSM00158, which showed the strongest inhibition of the CtBP2-p300 interaction in vitro. Our results indicated that NSM00158 could specifically disrupt CtBP2 function and cause the disassociation of the CtBP2-p300-Runx2 complex. The impairment of this complex led to failed binding of Runx2 to its downstream targets, causing their upregulation. Using a mouse fracture model, we evaluated the in vivo effect of NSM00158 on preventing nonunion. Consistent with the in vitro results, the NSM00158 treatment resulted in the upregulation of Runx2 downstream targets. Importantly, we found that the administration of NSM00158 could prevent the occurrence of nonunion. Our results suggest that NSM00158 represents a new potential compound to prevent the occurrence of nonunion by disrupting CtBP2 function and impairing the assembly of the CtBP2-p300-Runx2 transcriptional complex.
Body Condition Scores at Calving and Their Association with Dairy Cow Performance and Health in Semiarid Environment Under Two Cooling Systems

Under tropical environments cow’s body condition at calving may influence productivity and health performance. Therefore, the current research evaluated the impact of body condition score (BCS) at calving on milk production traits and health problems of primiparous and multiparous cows raised under two cooling systems in semi-arid environment. Milk yield parameters and health disorders data at different parities were obtained from 1700 Holstein cows, which were managed under Korral Kool (KKC) and fan (FC) cooling systems in Saudi Arabia. The results revealed that KKC system induced high level of milk production improvement (305TM, days in milk, daily milk yield) (P<0.05) compared to FC, especially in multiparous cows. There was an advantage of the high BCS group under KKC system over the FC system for peak yield and period. Cows from both cooling systems having moderate BCS outdid the other groups for total milk yield. Low BCS primiparous cows reared under KKC system were the most to suffer from stillbirth (18%), and calving ease (26.1%) in winter, while high BCS were the most to be treated for mastitis (8.5% in summer). On the other hand, spring calved multiparous cows raised under FC system suffered more from lameness (21.57% - high BCS) and milk fever (4.4% - moderate BCS). Further, cows having moderate BCS kept under KKC system had the highest incidence of lameness (62.2%), and abomasum displacement (4.4%). In conclusion, achieving correct BCS at calving and cooling system is important to avoid calving subsequent lactation performance and metabolic disease losses.
ATRAID regulates the action of nitrogen-containing bisphosphonates on bone

ATRAID is essential for responses to the commonly prescribed osteoporosis drugs nitrogen-containing bisphosphonates. Screening for side effect susceptibility Osteoporosis is typically treated with nitrogen-containing bisphosphonates (N-BPs), which inhibit bone resorption; however, N-BPs can cause serious side effects including osteonecrosis of the jaw and fracture. To understand susceptibility to these side effects, Surface et al. investigated the role of the gene ATRAID in mediating responses to N-BPs. Atraid-deficient mice had weaker bones and did not respond to N-BP treatment in models of osteoporosis, and patients with coding variants in ATRAID taking N-BPs presented with atypical fractures and osteonecrosis of the jaw. The authors determined that ATRAID is necessary for inhibition of osteoclast function by N-BPs. Results suggest that it may be prudent to screen patients for variants in ATRAID to avoid N-BP side effects. Nitrogen-containing bisphosphonates (N-BPs), such as alendronate, are the most widely prescribed medications for diseases involving bone, with nearly 200 million prescriptions written annually. Recently, widespread use of N-BPs has been challenged due to the risk of rare but traumatic side effects such as atypical femoral fracture (AFF) and osteonecrosis of the jaw (ONJ). N-BPs bind to and inhibit farnesyl diphosphate synthase, resulting in defects in protein prenylation. Yet, it remains poorly understood what other cellular factors might allow N-BPs to exert their pharmacological effects. Here, we performed genome-wide studies in cells and patients to identify the poorly characterized gene, ATRAID. Loss of ATRAID function results in selective resistance to N-BP–mediated loss of cell viability and the prevention of alendronate-mediated inhibition of prenylation. ATRAID is required for alendronate inhibition of osteoclast function, and ATRAID-deficient mice have impaired therapeutic responses to alendronate in both postmenopausal and senile (old age) osteoporosis models. Last, we performed exome sequencing on patients taking N-BPs that suffered ONJ or an AFF. ATRAID is one of three genes that contain rare nonsynonymous coding variants in patients with ONJ or an AFF that is also differentially expressed in poor outcome groups of patients treated with N-BPs. We functionally validated this patient variation in ATRAID as conferring cellular hypersensitivity to N-BPs. Our work adds key insight into the mechanistic action of N-BPs and the processes that might underlie differential responsiveness to N-BPs in people.
Modeling xylan solubilization during autohydrolysis of sugar maple wood meal: Reaction kinetics

Abstract The objective of this work was to study the kinetics of hemicelluloses extraction during hydrothermal pretreatment of sugar maple wood meal. Pretreatment was conducted in a batch reactor at 145–185°C with reaction times up to 8 h and with liquor to solid ratio of 20:1. Under these conditions, hemicelluloses were selectively solubilized and little degradation (approximately 6–9% of the initial amount) of cellulose and lignin was observed. A kinetic model was developed. It was supposed that there are no diffusion limitations and that the reaction rate constants have first-order kinetics with Arrhenius-type temperature dependence. The model proposes the formation of xylose directly from wood xylan as well as from xylooligomers formed in the liquid phase by the hydrolysis of xylan. The model is able to correlate satisfactorily experimentally measured yields of residual xylan, xylooligomers, xylose, and furfural obtained during the pretreatment.
