Objective To describe regional experiences and measures implemented to safely maintain obstetrics and gynecology services during the COVID-19 pandemic at King Abdullah University Hospital in Jordan. Methods All policies and measures were implemented in keeping with World Health Organization and other international recommendations and guidelines. Results With concerted effort and a multidisciplinary approach, most maternity and gynecology services were provided and all other training and educating responsibilities were maintained. Conclusion COVID-19 caused an unprecedented global healthcare crisis. Our institution addressed the challenges and implemented several measures at different levels to maintain services and facilitate the training and teaching of trainees and medical students.Background Pituitary pars intermedia dysfunction (PPID) is commonly investigated using plasma ACTH concentrations but problems exist with currently available diagnostic thresholds. Objectives To derive temporally specific diagnostic thresholds for equine plasma ACTH concentration to be used alongside clinical judgement in each individual week of the year and appropriate for the degree of clinical suspicion in any given case. Furthermore, to apply these thresholds to compare the prevalence of high and low ACTH in two subgroups of animals with high and low clinical suspicion of PPID. Study design A retrospective population study examining a large laboratory database of equine plasma ACTH concentrations using an indirect approach to calculate diagnostic thresholds. Methods Logs of plasma ACTH concentrations from 75 892 individual horses were examined using robust L2 estimation of mixtures of two normal distributions in categories of each week and month of the year. Thresholds dividing the two populations of highagnosis is deemed least desirable.A recent article published in Nature Metabolism, "A network of trans-cortical capillaries as a mainstay for blood circulation in long bones," explained the long bone vascularity. In the mouse model, the authors demonstrated hundreds of transcortical vessels (TCVs) commencing from the bone marrow and traversing the whole cortical thickness. They realized that TCVs were the same as bleeding vessels of periosteal bed observed in the human tibia and femoral epiphysis during surgery. TCVs expressed arterial or venous markers and were proposed to be the backbone of bone vascularity as 80% of arterial and 59% of venous blood distributed through them. This new evidence challenged the existence of the "cortical capillaries" stated in previous literature. We conducted a review of the existing literature to compare this model with those in earlier research. The bone vascularity model was explained by many researchers who did their work in animal models like pig, dog, rabbit, and mouse. The TCVs were identified in these animal model studies as cortical capillaries or vessels of cortical canals. Studies are scarce, showing the presence of TCVs in humans. The role of TCVs in human cortical vascularity remains ambiguous until the substantial evidence is collected in future studies.The novel coronavirus (CoV), severe acute respiratory syndrome (SARS)-CoV-2 is an international public health emergency. Until now, the intermediate host and mechanisms of the interspecies jump of this virus are unknown. Phylogenetic analysis of all available bat CoV complete genomes was performed to analyze the relationships between bat CoV and SARS-CoV-2. To suggest a possible intermediate host, another phylogenetic reconstruction of CoV genomes obtained from animals that were hypothetically commercialized in the Chinese markets was also carried out. Moreover, mutation analysis was executed to suggest genomic regions that may have permitted the adaptation of SARS-CoV-2 to the human host. The phylogenetic analysis demonstrated that SARS-CoV-2 formed a cluster with the bat CoV isolate RaTG13. Possible CoV interspecies jumps among bat isolates were also observed. The phylogenetic tree reconstructed from CoV strains belonging to different animals demonstrated that SARS-CoV-2, bat RaTG13, and pangolin CoV genomes formed a monophyletic cluster, demonstrating that pangolins may be suggested as SARS-CoV-2 intermediate hosts. Three AA substitutions localized in the S1 portion of the S gene were observed, some of which have been correlated to structural modifications of the S protein which may facilitate SARS-CoV-2 tropism to human cells. Our analysis shows the tight relationship between SARS-CoV-2 and bat SARS-like strains. It also hypothesizes that pangolins might have been possible intermediate hosts of the infection. Some of the observed AA substitutions in the S-binding protein may serve as possible adaptation mutations in humans but more studies are needed to elucidate their function.Some situations may require endoscopy during the COVID-19 (Coronavirus Disease 2019) pandemic. Here, we describe the necessary precautions in the form of clinical questions and answers (Q&A) regarding the safe deployment of gastrointestinal endoscopy in such situations while protecting endoscopy staff and patients from infection. Non-urgent endoscopy should be postponed. The risk of infection in patients should be evaluated in advance by questionnaire and body temperature. The health of staff must be checked every day. Decisions to employ endoscopy should be based on the institutional conditions and aims of endoscopy. All endoscopic staffs need to wear appropriate personal protective equipment (PPE). The endoscope and other devices should be cleaned and disinfected after procedures in accordance with relevant guidelines. Optimal management of the endoscopy unit is required. Endoscopy for infected patients or those with suspected infection demands exceptional caution. When a patient who undergoes endoscopy is later found to have COVID-19, the members of staff involved are considered exposed to the virus and must not work for at least 14 days if their PPE is considered insufficient. When PPE resources are limited, some equipment may be used continuously throughout a shift as long as it is not contaminated. Details of the aforementioned protective measures are described.The introduction of NBS in Ireland in July 2011, provided a unique opportunity to investigate clinical outcomes using a comparative historical cohort study. Clinical cohort children clinically diagnosed with CF born 1 July 2008 to 30 June 2011, and NBS cohort children diagnosed with CF through NBS born 1 July 2011 to 30 June 2016. read more Clinical data were collected from the CF Registry of Ireland, medical charts, and data on weight/height before diagnosis from public health nurses and family doctors. SPSS was used for analysis. A total of 232 patients were recruited (response 93%) (93 clinically diagnosed, 139 NBS-detected). Following exclusions of meconium ileus (MI) (40), diagnosis outside Ireland (4), and being designated as CFSPID (2), a total of 77 clinically diagnosed patients and 109 NBS detected children were included in analysis. Over half were homozygous for F508del mutation. Being clinically diagnosed was independently associated with hospitalization for infective exacerbation of CF less then 36 months (OR, 2.80; 95%CI 1.24-6.29). Diagnosis to first acquisition of Pseudomonas aeruginosa was significantly longer in NBS than clinically detected; from birth there was no significant difference. Weight and length/height were significantly greater in NBS cohort at 6 and 12 months. We provide evidence of improved growth, reduced hospitalization for acute exacerbations, and delayed P. aeruginosa acquisition (from diagnosis) to age 3 for the NBS cohort. Screening practices likely account for the non-significant difference in P. aeruginosa acquisition from birth.Hand, foot, and mouth disease (HFMD) caused by enterovirus 71 (EV71) can lead to high morbidity and mortality, and genetic background plays an important role during the disease process. We investigated the association between the single-nucleotide polymorphism (SNP) rs2564978 of the CD55 gene and susceptibility to and severity of HFMD using the SNPs can multiple SNP typing methods. Soluble CD55 (sCD55) expression was significantly lower in the EV71 HFMD group than in the control group and lower in severe cases than in mild cases (P less then .001). Moreover, CD55 rs2564978 (C vs T OR = 1.300, 95% CI, 1.120-1.509) was associated with the risk of EV71 infection, and genotype TC was related to the severity of the infection (TC vs TT OR = 4.523, 95% CI, 2.033-10.066). Our results suggest that sCD55 expression and the CD55 polymorphism rs2564978 may influence the susceptibility to and severity of EV71 infection.To assess whether far-cortical locking (FCL) screws alter the fracture site strain environment and allow shorter bridge plate constructs for supracondylar femoral fractures, we tested the fracture site displacement under force of synthetic left femora with a 5-cm metaphyseal fracture gap, modeling comminution. Five models of nine constructs were tested (three types of diaphyseal screws [nonlocking, locking, and FCL] and two plate lengths [13 holes and 5 holes]). Long plate models using three or four diaphyseal screws (working length 13.5 or 7.5 cm, respectively) were compared with short plates with three diaphyseal screws (working length 7.5 cm). Models were loaded axially and torsionally; 100 cycles in random order. Primary outcome measures were axial and torsional fracture site stiffness. FCL screws decreased rotational stiffness 19% (P less then .01) compared with baseline nonlocking screws in the same plate and working length construct, mirroring the effect (20% decrease in stiffness, P less then .01) of nearly doubling the nonlocking construct working length (7.5-13.5 cm). Similarly, FCL screws decreased axial stiffness 23% (P less then .01) in the same baseline comparison. Fracture site displacement under loading comparable to a long working length nonlocked plate construct was achieved using a shorter FCL plate construct. By closely replicating the biomechanical properties of a long plate construct, a fracture site strain environment considered favorable in promoting fracture healing might still be achievable using a shorter plate length. Clinical Significance It might be possible to optimize fracture site strain environment and displacement under loading using shorter FCL plate constructs. Orthopaedic Research Society.

Restrospective analysis of clinical data of 85 patients infected with SARS-CoV-2, including gender, age, comorbidities, symptoms, blood routine, clotting profile, biochemical examination, albumin, myocardial enzyme profile, inflammatory markers, and chest CT. All laboratory examination were measured within first 24 hours after admission, and chest CT were performed before admission. 56 (65.9%) patients had a history of exposure to Huanan seafood market in Wuhan. Fever and dry cough accounted for the highest percentage of all symptoms. Male COVID-2019 patients were more likely to develop severe pneumonia. Patients with severe and critical conditions are older and have higher rates of hypertension (p=0.003) and coronary heart disease (p=0.017). All severe and critical patients infected with SARS-CoV-2 showed bilateral lung involvement and have more multiple lobes involvement than common patients (p less then 0.
