Dualized gravity beyond linear approximation
Authors: Wani Salman Sajad , Tsun Tsou Sheung , Faizal Mir 
Published: August 2022

AbstractWe will construct a loop space formalism for general relativity, and construct the Polyakov variables as connections for such a loop space. We will use these Polyakov variables to construct a dual theory of gravity beyond linear approximation. It will be demonstrated that this loop space duality reduces to the Hodge duality for linearized gravity. Furthermore, a loop space curvature will be constructed from this Polyakov variable. It will be shown that this loop space curvature vanishes in the absence of topological defects, and so it can be used to investigate gravitational monopoles. We will also construct the suitable monopole charge for such gravitational monopoles.

Varying coupling constants and their interdependence
Authors: Gupta Rajendra P. 
Published: August 2022

Since Dirac predicted in 1937 the possible variation of gravitational constant and other coupling constants from his large number hypothesis, efforts continue to determine such variation without success. Such efforts focus on the variation of one constant while assuming all others pegged to their currently measured values. We show that the variations of the speed of light [Formula: see text], the gravitational constant [Formula: see text], the Planck constant [Formula: see text], and the Boltzmann constant [Formula: see text] are interrelated: [Formula: see text]. Thus, constraining any one of the constants leads to inadvertently constraining all the others. It may not be possible to determine the variation of a constant without concurrently considering the variation of others. We discuss several astrophysical observations that have been explained recently with the concomitant variation of two or more constants. We also analyze the reported and unexplained 35 [Formula: see text]g decrease of 1 Kg Pt-Ir working standards over 22 years of measurements and show that they can be accounted for by allowing [Formula: see text], [Formula: see text], and [Formula: see text] to vary as predicted, provided such mass decrease can be confirmed with a Kibble balance used for determining the Planck constant and weighing test-masses with extreme precision.

Published: August 2022

Objective. To understand the oral health self-management ability status and influencing factors among adolescent patients with fixed orthodontics in Nanjing and to provide a reference for formulating targeted intervention measures. Methods. A mixed research method was used. First, the convenience sampling method was used to select adolescent patients with fixed orthodontics admitted to the orthodontic department of a dental hospital in Nanjing from November 2021 to March 2022. The oral health self-management ability questionnaire was used for the investigation; then, 15 children with poor oral health management ability were selected for in-depth interviews. Results. The total score of oral health self-management ability of 290 adolescent children with fixed orthodontics was 45.6-90.8 points, with an average score of

. Multiple regression analysis showed that sex, age, bracket wearing time, grade, and place of residence were related to the scores of each dimension of self-management. Qualitative research shows that the main reasons for the poor oral health self-management ability of adolescents with fixed orthodontics are the lack of awareness during fixed orthodontics, lack of knowledge channels, low compliance, inability to solve oral problems during treatment, difficulty in adhering to oral care behaviors, and lack of motivation to treat. Conclusion. The oral health self-management ability of adolescent children with fixed orthodontics needs improvement, and a precise health intervention plan should be formulated.

Background. Large urinary bladder stones are not common and even less common in females. We report a case of large bladder stone presented with acute retention of urine in a female patient. Case Report. A 62-year-old female presented in emergency department with retention of urine for 12 hours with history of recurrent UTIs for last 1 year. She was also complaining of mild dull lower abdominal pain for last 6 months. She had no history of incontinence of urine and fever. On physical examination, hard mass was palpable on suprapubic region on palpation of abdomen. Urine culture shows Escherichia coli for which antibiotics was given. An X-ray kidney ureter bladder showed a radio-opacity in the pelvic region measuring

in size. Ultrasonography revealed bilateral mild hydronephrosis with a large bladder stone. Open cystolithotomy was performed, and the stone was taken out. Stone biochemical analysis showed predominantly urate crystals. Patient had uneventful postoperative course, and she was discharged on 4th postoperative day and was followed up for 1 months after operation. Conclusions. Large urinary bladder stones are not common and even less common in females. Clinician should have think regarding large bladder stone as a cause of recurrent lower urinary tract symptoms like dysuria and should assess renal function for proper treatment. Open cystolithotomy is choice of operation in large bladder stone.

Objective. To offer a baseline for clinical diagnosis, echocardiography was performed to evaluate the disparities in heart function comparing pregnant women with diabetes mellitus (GDM) and ordinary pregnant women. Methods. A prospective case-control study is being conducted on pregnant women with or without gestational diabetes. The sample size for both the intervention and control groups is the same: no diabetes diagnosis or previous forms, a single pregnancy, and no issues (such as preeclampsia or fetal growth restriction). The females were all subjected to routine echocardiograms to examine the morphology and function of their left and right hearts. Results. In the research, 51 women with GDM and 50 healthy controls volunteered. Women with GDM had a significantly higher heartrate (

This study focuses on the effect of electrolyte parameter variation upon the performance of lithium iron phosphate (LiFePO4) due to high demand of the electronic devices among consumers and industrial sectors that require efficicent LiFePO4 batteries. Hence, it is essential to improve its performance by optimizing the electrolyte parameter of the cell. The mathematical models of lithium-ion batteries based on the drift-diffusion model consists of the electrolyte and lithium transport equations in the electrode particles which incorporated the geometry of cell microstructure to the coefficients in the macroscopic model was solved numerically using the method of lines (MOL) technique. The effect of electrolyte parameter variation on the discharge curve of LiFePO4 using lithium hexa-fluoro-phosphate (LiPF6 ) as the base electrolyte is examined by varying the electrolyte parameters: initial concentration of lithium ions (c0), the effective diffusivity of lithium ions (D) and the effective ionic conductivity (𝜅). The simulations show that higher diffusivity of lithium ions produces large discharge curve and higher ionic conductivity increase the mobility of the ion in the cell. Meanwhile, higher initial concentration of lithium ions produced high battery performance compared to lower initial concentration of lithium ion resulting more discharge time before electrolyte depletion occurs.

Background:
Administrative claims for aortic stenosis (AS) regurgitation may be useful, but their accuracy and ability to identify individuals at risk for valve-related outcomes have not been well characterized.

Methods:

Using echocardiographic (transthoracic echocardiogram [TTE]) reports linked to US Medicare claims, 2017 to 2018, the performance of candidate
International Classification of Diseases, Tenth Revision
claims to ascertain AS/aortic regurgitation was evaluated. The optimal performing algorithm was tested against outcomes at 1-year after TTE in a separate 100% sample of US Medicare claims, 2017 to 2019.

Results:

Of those included in the derivation (N=5497, mean age 74.4±11.0 years, 49.7% female), any AS or aortic regurgitation was present in 24% and 38.8%, respectively. The sensitivity and specificity of
International Classification of Diseases, Tenth Revision
code I35.0 for identification of any AS was 53.1% and 94.8%, respectively. Among those with an I35.0 code, 40.3% had severe AS. Claims were unable to distinguish disease severity (ie, severe versus nonsevere) or subtype (eg, bicuspid or rheumatic AS), and were insensitive and nonspecific for aortic regurgitation of any severity. Among all beneficiaries who received a TTE (N=4 033 844), adjusting for age, sex, and 27 comorbidities, those with an I35.0 code had a higher adjusted risk of all-cause mortality (adjusted hazard ratio, 1.33 [95% CI, 1.31–1.34]), heart failure hospitalization (adjusted hazard ratio, 1.37 [95% CI, 1.34–1.41]), and aortic valve replacement (adjusted hazard ratio, 34.96 [95% CI, 33.74–36.22]).

Conclusions:

Among US Medicare beneficiaries receiving a TTE,
International Classification of Diseases, Tenth Revision
claims, though identifying a population at significant greater risk of valve-related outcomes, failed to identify nearly half of individuals with AS and were unable to distinguish disease severity or subtype. These results argue against the widespread use of

claims to screen for patients with AS and suggests the need for improved coding algorithms and alternative systems to extract TTE data for quality improvement and hospital benchmarking.
Hepatocellular-Cholangiocarcinoma Collision Tumors: An Update of Current Management Practices
Authors: Goodwin Brandon , Lou Johanna , Butchy Margaret , Wilson Traeden , Atabek Umur , Spitz Francis , Hong Young 
Published: August 2022

Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a rare form of primary hepatic collision tumor, with an incidence ranging from 0.4 to 14.2%. Given the diagnostic challenges and lack of randomized trials, standardized treatment has yet to be established. We aim to review the literature to summarize the diagnosis, molecular characteristics, current treatment modalities, and challenges for cHCC-CC. A literature review was performed using PubMed. We included studies investigating and describing cHCC-CC, focusing on surgical, medical, and radiologic treatments. Overall prognosis is poor, with a 5-year survival rate under 30%. Minor or major hepatectomy with R0 resection is the only curative treatment; however, recurrence is likely (as high as 50% within 5 years). The role of liver transplantation is also highly debated given the biliary nature of these tumors, with cHCC-CC as a relative contraindication for liver transplantation. Although gemcitabine-based treatments had higher progression-free survival over sorafenib, there is no standard chemotherapy regimen. Treatment with gemcitabine and platinum demonstrates improved disease control rates compared to gemcitabine in conjunction with 5-fluorouracil (78.4% verse 38.5% respectively). Additionally, platinum-containing chemotherapy regimens exhibit a higher overall response rate than non-platinum regimens (21.4% verse 7.0% respectively). These molecular-directed therapies have prolonged survival for HCC, but further investigation needs to be done to assess their utility in patients with cHCC-CC. cHCC-CC is a rare and complex subset of primary hepatic neoplasms with a dismal prognosis and unstandardized treatment options. Further trials need to be performed to investigate systemic chemotherapy and immunotherapy options for patients with unresectable disease.
Indications and Outcomes of Completion Cholecystectomy: A 5-year Experience From a Rural Tertiary Center
Authors: Alser Osaid , Dissanaike Sharmila , Shrestha Kripa , Alghoul Heba , Onkendi Edwin 
Published: August 2022

Background Completion cholecystectomy (CC) is performed for recurrent or persistent biliary symptoms following subtotal cholecystectomy (STC) or incomplete cholecystectomy (IC). Due to its complexity, cases are often referred to hepato-pancreato-biliary (HBP) surgeons. There is little published literature on indications or outcomes of CC. Methods Completion cholecystectomy cases performed between 2016 and 2021 by the sole HPB surgeon covering a rural referral base of >250-mile radius in West Texas were included. Primary variables of interest include indications and outcomes of CC. Results Of the eleven patients included, 5 (45.5%) had laparoscopic STC, 3 patients (27.3%) had laparoscopic converted to open STC, and 2 (18.2%) had laparoscopic IC. Most STC cases (6/9, 66.6%) were reconstituting, while 3 STC cases were fenestrating (all had persistent bile leak). For reconstituting STC, indications were symptomatic cholelithiasis in 5 patients (45.5%), and choledocholithiasis in 3 patients (27.3%). The median (IQR) duration between index procedure and subsequent CC was 15 (1.4-92) months. The median (IQR) remnant gallbladder length was 4 (3-4.5) cm. Completion cholecystectomy was performed robotically in 8 cases (72.7%). Post-CC complications occurred in 3 patients (27.3%); these were 1 superficial surgical site infection, 1 hepatic abscess requiring percutaneous drainage, and lastly atrial fibrillation. Conclusions All patients requiring CC had residual gallbladder remnant >2.5 cm; this is longer than recommended for STC. Completion cholecystectomy is a complex operation that carries significant morbidity, even when performed using minimally invasive techniques. As bailout procedures become more common in severely inflamed cholecystitis, it is important to collate more data on the outcomes of requiring CC.
Do faecal test-based colorectal cancer screening pilots provide data that are reflected in subsequent programmes? Evidence from interval cancer proportions
Authors: Clark Gavin RC , Steele Robert JC , Fraser Callum G 
Published: August 2022

Objective Guidelines on colorectal cancer (CRC) screening with guaiac faecal occult blood tests (gFOBTs) and faecal immunochemical tests (FITs) include the need for a pilot before a programme is introduced. Interval cancers (ICs), cancers arising after a negative screening test result but before the next scheduled invite, are important indicators of programme quality. Our aim was to compare IC in the gFOBT-based Scottish Bowel Screening Programme (SBoSP), a FIT-based pilot, and the FIT-based SBoSP, to assess if the pilot provided data that was reflected in the subsequent programme. Design The IC proportions (ICPs) data ([IC/(IC + screen detected CRC)] x 100) from the penultimate year of the gFOBT-based SBoSP, the 6-month pilot and the first year of the FIT-based SBoSP were compared. To ensure appropriate comparison, these data were only from the two pilot NHS Boards. Results For all participants, and females and males, the ICPs were very similar in the gFOBT-based SBoSP and the pilot. The faecal haemoglobin concentration (f-Hb) threshold for the pilot was set at ≥80 μg Hb/g faeces. However, in marked contrast, in the FIT-based SBoSP, at the same threshold, the ICPs were lower. In all three groups, the ICPs were higher in females than in males. Conclusions Data on variables in pilots, including ICP, can be informative, but only if variables such as FIT system are held consistent between pilot and programme. Lowering the f-Hb threshold for females to give the same ICP as males might be a strategy to minimise sex inequality.

Published: August 2022

Our aim in this study was to compare the dynamic balance between runners (100 sprint) and non-runners with intellectual disability (ID). Our participants were 36 healthy male adults with ID aged 17–29 years, divided into runners ( n = 18) and sedentary non-runners ( n = 18). We assessed dynamic balance in these participants, using the Y-Balance Test (YBT), the Expanded-Timed Up and Go Test (ETUGT) and the Functional Reach Test (FRT). Runners with ID had significantly better balance scores than their sedentary counterparts on YBT (p < .001), the two walking phases of the ETUGT (p < .05) and the FRT (p <.05). Thus, running training (100 m sprint) was associated with better dynamic balance in this sample.
Numerical study on the performance of centrifugal blood pump with superhydrophobic surface
Authors: Li Chengcheng , Qiu Huihe , Ma Jianying , Wang Ying 
Published: August 2022

Aim: In order to reduce the blood damage of an artificial heart pump and optimize its hydraulic performance, a centrifugal blood pump with superhydrophobic characteristics is proposed in this study. Methods: To study the influence of superhydrophobic surface characteristics on the performance of centrifugal blood pumps, the Navier slip model is used to simulate the slip characteristics of superhydrophobic surfaces, which is realized by the user defined function of ANSYS fluent. The user defined functions with different values of slip length are verified by two benchmark solutions of laminar flow and turbulence in the pipeline. The blood pump model adopts the designed centrifugal blood pump, and its head, hydraulic efficiency and hemolysis index are calculated. The Navier slip boundary condition (a constant slip-length of 50 μm) is applied to the walls of the blood pump impeller and a volute at different positions, and the influence of the superhydrophobic surface on the performance of the blood pump at the design point Q = 6 L/min was compared and analyzed. Results: The results show that the centrifugal blood pump model used in this paper has good blood compatibility and meets the design requirements; the superhydrophobic surface can significantly reduce the scalar shear stress in the blood pump. At the design point, when the slip length is 50 μm, the mass-average scalar shear stress in the impeller area and the volute area reduction rate is about 5.9%, the hydraulic efficiency growth rate is about 3.8%, the hemolysis index reduction rate is about 18.4%, and the pressure head changes little with a growth rate of 0.3%. Conclusions: Centrifugal blood pumps with superhydrophobic surfaces can improve the efficiency of blood pumps and reduce hemolysis. Based on these encouraging results, vitro investigations for actual blood damage would be practicable.
