Statistical Distribution Model of Charpy Absorbed Energy in Transition Temperature Range for Reactor Pressure Vessel Steel
Authors: Miura Naoki , Shinko Tomoki 
Published: June 2023

Abstract
A statistical model to estimate the distribution characteristics of Charpy absorbed energy in the transition temperature range was proposed based on the variation in fracture toughness addressed by the Master Curve and the relationship between fracture toughness and Charpy absorbed energy associated with the Charpy Master Curve. Charpy absorbed energy in the transition temperature range can be well approximated by both the Weibull and normal distributions, and the parameters to determine the shape of the distributions (scale and shape parameters of the Weibull distribution, mean and standard deviation of the normal distribution) can be deductively defined as the functions of two independent variables, median of the fracture toughness and the difference between reference temperature and Charpy reference temperature. A series of Charpy impact tests were conducted under the same conditions to obtain the characteristics of the variation in Charpy absorbed energy for a reactor pressure vessel steel SQV2A base metal, and the experimental variation was reasonably predicted by the proposed model.
Anti-synthetase syndrome masquerading as recurrent pneumonia
Authors: Lio Ka U , Li Si 
Published: June 2023

Anti-synthetase syndrome (ASS) is a rare inflammatory myopathy with a wide variety of clinical presentations. ASS-related interstitial lung disease (ASS-ILD) presents with rapid onset and progression, which could often be confused with other more common acute processes such as pneumonia, especially when ILD can be the sole manifestation. A woman in her 50s presented with recurrent dyspnoea for 2 months requiring multiple hospital admissions, and each time, she was diagnosed with multifocal pneumonia and treated with antibiotics. On admission, the evaluation revealed a markedly elevated creatine kinase level at 3258 U/L and a CT scan of the chest revealed worsening scattered ground-glass opacities. Given the concern for ILD as the cause of antibiotic failure, she underwent bronchoscopy with bronchoalveolar lavage which revealed non-specific interstitial pneumonia. A subsequent myositis panel revealed a positive anti-Jo-1 antibody, and she was diagnosed with ASS-ILD. She completed a course of intravenous immunoglobulin and methylprednisolone and experienced significant clinical improvement with the resolution of hypoxaemia and improved polyarthralgia.ASS could often be misdiagnosed as other more common acute lung processes, as a clinically subtle course can escape detection given its rarity, as well as its non-specific and highly variable presentations. This case highlights the importance of early suspicion and consideration of performing specific autoantibody testing when evaluating patients with a suspicion of undifferentiated autoimmune condition.

Abstract
The BASE collaboration at the antiproton decelerator/ELENA facility of CERN compares the fundamental properties of protons and antiprotons with ultra-high precision. Using advanced Penning trap systems, we have measured the proton and antiproton magnetic moments with fractional uncertainties of 300 parts in a trillion (p.p.t.) and 1.5 parts in a billion (p.p.b.), respectively. The combined measurements improve the resolution of the previous best test in that sector by more than a factor of 3000. Very recently, we have compared the antiproton/proton charge-to-mass ratios with a fractional precision of 16 p.p.t., which improved the previous best measurement by a factor of 4.3. These results allowed us also to perform a differential matter/antimatter clock comparison test to limits better than $$3\,$$

3

%. Our measurements enable us to set limits on 22 coefficients of CPT- and Lorentz-violating standard model extensions (SME) and to search for potentially asymmetric interactions between antimatter and dark matter. In this article, we review some of the recent achievements and outline recent progress towards a planned improved measurement of the antiproton magnetic moment with an at least tenfold improved fractional accuracy.

On quarkonium masses in 3D non-commutative space
Authors: Bukor Benedek , Tekel Juraj 
Published: June 2023

AbstractWe modify the calculation of quarkonium masses using the radial WKB and Pekeris-type approximations for the case of three-dimensional, rotationally invariant non-commutative space. We obtain corrections to the charmonium ($${\text {c}}\bar{{\text {c}}}$$cc¯), bottomonium ($${\text {b}}\bar{{\text {b}}}$$bb¯) and bottom-charmed meson ($${\text {c}}\bar{{\text {b}}}$$cb¯) masses due to the discrete short distance structure of the space introduced by the space non-commutativity. For the fundamental length at the Planck scale we obtain relative correction at the order of$$10^{-39}$$10-39, and taking into account the current experimental data, we obtain the upper bound at the order of$${10^{-18}\,{{\text {m}}}}$$10-18mfor the fundamental length scale of space.

Authors: Yeh Chun , Lin Chia-Yu , Chen Hsien-Te 
Published: June 2023

Study Design: Retrospective case analysis and systematic literature review. Objective: To comprehensively review minimally invasive surgery (MIS) for post-traumatic kyphosis. Methods: A systematic PubMed search was conducted for MIS and kyphotic deformities were published between 2012 and 2022. Sixteen patients between 2017 and 2021 met the criteria. Demographic data, surgical characteristics, and full-length radiographic parameters were collected pre- and post-operatively, and at final follow-up. Results: Twenty-three articles were included. The mean age was 67 years, and the mean follow-up was 17 months. The mean operative time was 331 min and blood loss was 252 ml. Pre-operative radiographic outcomes were as follows: Lumbar lordosis (LL), [Formula: see text]; pelvic incidence (PI), [Formula: see text]; PI-LL mismatch, [Formula: see text]; pelvic tilt (PT), [Formula: see text]; and sagittal vertical axis (SVA), [Formula: see text] mm. At the final follow-up, LL was [Formula: see text] ([Formula: see text] = 0.51229), PI was [Formula: see text] ([Formula: see text] = 0.61438), PI-LL mismatch was [Formula: see text] ([Formula: see text] = 0.74696), PT was [Formula: see text] ([Formula: see text] = 0.00386), and SVA was [Formula: see text] mm ([Formula: see text] = 0.00465). The mean ODI and VAS scores for back pain at baseline and at 96 months follow-up were 33.2–19.7 and 8.4–2.5, respectively. Conclusion: Age-adjusted MIS provides correction of sagittal alignment for posttraumatic kyphosis that satisfies patient demand.

Published: June 2023

We present the production and extensive characterization of a polyacrylamide (PAAm)/polyvinyl alcohol (PVA) polymeric blend doped with varying percentages of cadmium sulfide (CdS) nanoparticles (NPs). Using the solution casting method, CdS-filled PVA/PAAm polymeric nanocomposite (PNCs) films in various weight ratios and percentages were created. The SEM pictures confirmed the identical spreading of CdS NPs in the mix. The filler CdS material might be used to modify the optical characteristics. The film’s direct optical energy gap ([Formula: see text] (dir.)) has been adjusted from 2.30[Formula: see text]eV to 3.30[Formula: see text]eV. The intermolecular interactions of the PVA/PAAm mix were investigated using FT-IR analysis. The electrical properties of alternating current were studied throughout a frequency range of 100[Formula: see text]Hz–5[Formula: see text]MHz. The impact of CdS NPs on the dielectric coefficient ([Formula: see text], dielectric loss ([Formula: see text] and ac conductivity ([Formula: see text] of PVA/PAAm PNCs over a range of frequencies at room temperature has been investigated. With increased CdS NPs, the attenuation coefficient values rose. We demonstrated that doping CdS composites with PVA/PAAm increases the antibacterial (ANB) activity of the composites. As a result of these findings, the PNCs films are appropriate for gamma-ray shielding (GRS) and ANB applications.

Published: June 2023

Objectives: Otomatch.com is an online forum for residency applicants to discuss the otolaryngology match process including academic metrics. The purpose of this study is to assess the accuracy of self-reported match data on Otomatch relative to official data reported by the National Residency Match Program (NRMP) and the Association of American Medical Colleges (AAMC). Methods: Data was collected from publicly editable Otomatch forums (2017-2018, 2018-2019, 2019-2020) and curated Otomatch survey responses (2018-2019, 2019-2020) whose results are released after Match Day. Aggregated data was collected from the NRMP 2018 and 2020 Charting Outcomes in the Match and AAMC Report on Residents (2017-2018, 2018-2019). Measures of interest included Step 1 scores, Step 2 CK scores, publications, number of interview invitations, number of interviews attended, and AOA status. ANOVA and 2 tailed T tests were performed to compare variables within each match year. Results: Average Step 2 CK score was significantly higher on publicly editable Otomatch forums than AAMC in 2017-2018 (257vs 253, P < .05) and 2018-2019 (258vs 252, P < .05). Interviews attended were significantly higher on Otomatch survey responses than the publicly editable forum in 2019-2020 (13vs 9, P-value < .05). Step 1 scores, interview invitations, and AOA status were not statistically significantly different when data was available. Conclusion: Applicant statistics from online forums, online surveys, NRMP, and AAMC are consistent, except for Step 2 CK scores. Self-reported data on the Otomatch forum is an accurate estimate of academic metrics of otolaryngology residency applicants.

Authors: Weaver Adam P. , Walaszek Michelle C. , Roman Dylan P. , Harkey Matthew S. , Kuenze Christopher 
Published: June 2023

Background: Treatment of meniscal injuries at the time of anterior cruciate ligament reconstruction (ACLR) can result in restrictions on weightbearing and range of motion in the early rehabilitative phases. What is unknown is the effect of (1) meniscal tear type and location at the time of anterior cruciate ligament injury and (2) meniscal treatment at the time of ACLR on quadriceps strength in adolescents during the late rehabilitative phase. Hypothesis: Meniscal tears involving the root and requiring repair would adversely affect quadriceps strength at 6 to 9 months postoperatively. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent ACLR at 1 of 2 research sites between 2013 and 2021 were identified. Adolescent participants were included if they were between the ages of 12 and 20 years at the time of assessment and had undergone primary unilateral ACLR in the previous 6 to 9 months. Participants were subgrouped by meniscal tear type (no tear, nonroot tear, root tear) and meniscal treatment at the time of ACLR (no treatment, meniscectomy, meniscal repair), which were confirmed via chart review. Isokinetic strength testing occurred at 60 deg/s, and quadriceps strength and quadriceps strength limb symmetry index were compared between the meniscal tear type and meniscal procedure subgroups using analysis of covariance while controlling for the effects of age, sex, and ACLR graft source. Results: An overall 236 patients were included in this analysis (109 male, 127 female; mean ± SD age, 16.0 ± 1.9 years). There were no significant differences in ACLR limb quadriceps strength based on meniscal tear type ( P = .61) or meniscal procedure at the time of ACLR ( P = .61), after controlling for age, biological sex, and ACLR graft source. Similarly, quadriceps strength limb symmetry index did not differ by meniscal tear type ( P = .38) or meniscal procedure at the time of ACLR ( P = .40). Conclusion: Meniscal tear type and treatment at the time of ACLR did not affect quadriceps strength or quadriceps strength symmetry in adolescents 6 to 9 months after ACLR.

Authors: Kinney Rachel , Praamsma Noah , Malinowski Amy , Cassi Patricia , Hennessy Erin 
Published: June 2023

Background: Recent calls-to-action have recommended the use of gender-inclusive language in the field of human lactation research and clinical care. However, little empirical evidence about parental acceptance and understanding of this new terminology exists. Research Aim: To assess understanding and acceptance of an inclusive language revision of the Breastfeeding Attrition Prediction Tool (BAPT). Methods: This was a prospective qualitative study consisting of two phases, a survey followed by cognitive interview. Pregnant people ( N = 16) were recruited from the Vermont Special Supplemental Nutrition Program for Women, Infants, and Children, which uses the BAPT as a standard of care. The study team revised the BAPT (e.g., changed terms like “breast milk” to “human milk”). Study participants completed the Revised BAPT and then participated in a cognitive interview by phone to assess their understanding and acceptance of revised, inclusive language. Results: Most inclusive language was well understood and accepted by participants. Proposed revisions to the survey to replace terms like “breastfeeding” with other terms like “chestfeeding” or “bodyfeeding” were more difficult for participants to understand and were not well accepted. Conclusions: While it is clear that language in human lactation research and clinical practice should be revised to be more gender inclusive, specific inclusive terms elicit different levels of understanding and acceptance. Inclusive language options should be tested with target populations and more research is needed in this area.

Authors: Nisha  , Das Karobi , Sharma Renu , Ghosh Abhishek 
Published: June 2023

Introduction Alcohol use disorder (AUD) is also known as alcohol dependence or alcohol addiction. In India (2020), 160 million people are consuming alcohol; among them 57 million people are alcohol dependent (Eashwar et al., 2020, Journal of Family Medicine and Primary Care, Vol. 9, 1, p. 49). Currently, it is a major public concern. Because AUD not only affects the patients physically but also affects person’s other life aspects such as mental health, social status, financial status, spirituality, and occupation. Objective To assess the alcohol use pattern and problems due to alcohol use among patients with AUD registered in the Drug De-Addiction and Treatment Centre, PGIMER, Chandigarh. Methodology An exploratory study was conducted among 40 participants who were enrolled by purposive sampling technique. Participants were enrolled after written informed consent and interviewed as per the interview schedule comprised sociodemographic data, clinical data, and performa to assess the problems associated with alcohol use. Data coding and analysis were done with SPSS (version 26). Results More than half of the study participants (57.5%) were from the age group of 36 to 55 years with a mean age of 40.55 ± 8.941 years ranging from 24 to 58 years; all were men and 70% of participants were from upper class socioeconomic status. Nearly half (47.5%) of the participants started drinking before 20 years of age and 50% participants had been drinking alcohol for more than 15 years. Participants had many problems such as gastric disorder (80%), weight loss (55%), inefficiency at work (92.5%), increased alcohol-related expenses (88.5%), reduced sources and amount of earning (57.5%), impaired interpersonal relationship (IPR) with family (97.5%), with spouse (80%), and in society (85%). Conclusion Patients with alcohal use disorder (AUD) have many problems in various aspects of their lives, that is, health, education, occupation, finance, family, marital life, and social life.
Cidofovir for Viral Infections in Immunocompromised Children: Guidance on Dosing, Safety, Efficacy, and a Review of the Literature
Authors: Riggsbee Daniel L. , Alali Muayad , Kussin Michelle L. 
Published: June 2023

Objective: To describe the use of cidofovir (CDV) for viral infections in immunocompromised children (IC) and provide guidance on dosing and supportive care. Data Sources: A PubMed search was conducted for literature published between 1997 and January 2022 using the following terms: cidofovir, plus children or pediatrics. Study Selection and Data Extraction: Limits were set to include human subjects less than 24 years of age receiving intravenous (IV) or intrabladder CDV for treatment of infections due to adenovirus, polyomavirus-BK (BKV), herpesviruses, or cytomegalovirus. Data Synthesis: Data were heterogeneous, with largely uncontrolled studies. Conventional dosing (CDV 5 mg/kg/dose weekly) was commonly used in 60% (31/52) of studies and modified dosing (CDV 1 mg/kg/dose 3 times/week) was used in 17% (9/52) of studies, despite being off-label. Nephrotoxicity reported across studies totaled 16% (65/403 patients), which was higher for conventional dosing 29 of 196 patients (15%) than modified dosing 1 of 27 patients (4%). Saline hyperhydration and concomitant probenecid remain the cornerstones of supportive care, while some regimens omitting probenecid are emerging to target BKV. Relevance to Patient Care and Clinical Practice: To our knowledge, this is the first comprehensive review of CDV use (indications, dosing, supportive care, response, and nephrotoxicity) in pediatric IC. Conclusions: Effective utilization of CDV in IC remains challenging. Further prospective studies are needed to determine the optimal CDV dosing; however, less aggressive dosing regimens such as modified thrice weekly dosing or low dosing once weekly omitting probenecid to enhance urinary penetration may be reasonable alternatives to conventional dosing in some IC.

Authors: Song In-Ae , Oh Tak-kyu , Do Sang-Hwan 
Published: June 2023

Introduction Magnesium sulfate is a potential anesthetic adjunct in cancer surgery. However, no definite consensus exists on the use of magnesium sulfate in patients undergoing major cancer surgery. Objective This study aimed to examine the trends and factors associated with magnesium sulfate administration in patients who underwent major cancer surgery in South Korea. Materials and Methods In this retrospective and population-based cohort study, we used 5-year health data that were extracted from the National registration database in South Korea from January 1, 2016 to December 31, 2020. All adult patients who underwent major cancer surgery during 2016–2020 in South Korea were included. Results In total, 253,538 patients were included. Among these patients, 6.6% (16,708/253,538) were administered magnesium sulfate during major cancer surgery. In multivariable logistic regression modeling, older age (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.02-1.02; P < .001), esophageal cancer surgery (vs lung cancer surgery [OR, 3.04; 95% CI, 2.80-3.30; P < .001]), increased Charlson comorbidity index score (OR, 1.03; 95% CI, 1.02-1.03; P < .001), mild-to-moderate disability (OR, 1.08; 95% CI, 1.03-1.14; P = .003), and severe disability (OR, 1.16; 95% CI, 1.05-1.27; P = .003) were associated with a higher incidence of perioperative magnesium sulfate administration for major cancer surgery. Video-assisted thoracoscopic surgery or laparoscopy (OR, .57; 95% CI, .55-.59; P < .001) and propofol-based total intravenous anesthesia (OR, .86; 95% CI, .82-.89; P < .001) were associated with a lower incidence of perioperative Mg sulfate administration for major cancer surgery. Conclusions In South Korea, 6.6% of the patients who underwent major cancer surgery were administered magnesium sulfate during surgery. Certain factors, such as old age, thoracic cancer surgery, open laparotomy or thoracotomy, greater comorbid status, and inhalation anesthesia, were potentially associated with magnesium sulfate administration in patients undergoing major cancer surgery.
Retrospective Analysis of the Real-World Utilization of 4-Factor Prothrombin Complex Concentrate and Plasma in Oral Anticoagulant-Associated Bleeding in US Hospitals

Published: June 2023

Real-world utilization of 4-factor prothrombin complex concentrate (4F-PCC) and plasma for the management of oral anticoagulant (OAC)-associated bleeding in US trauma hospitals was described. This is amulticenter, retrospective chart review evaluating the use of 4F-PCC and plasma in OAC reversal across medical specialties. Physicians completed a survey and extracted data from 3 to 5 patient charts. Variables of interest included medical specialty, urgency, and bleed type. Two hundred and thirty-five physicians completed the survey, and 861 patient charts were included in the study. 4F-PCC was commonly used in life-threatening or emergent indications, whereas plasma was used in emergent and urgent indications. Plasma was used mostly for patients on warfarin (53% vs 47% 4F-PCC) and 4F-PCC for those on apixaban (82% vs 18% plasma) and rivaroxaban (77% vs 23% plasma). This retrospective analysis showed that 4F-PCC was predominantly used for OAC reversal despite available specific reversal agents for some of the OAC. Although it is not recommended by any reversal guidelines, plasma is still used for OAC reversal. Plasma should be avoided in the management of OAC-associated bleeding.
