Authors: Khan Kamran , Chuadhry Arif , Schafer Charles , Pogson Kaylyn , Wood Jeyhan 
Published: January 2022

Abstract:Trigeminal trophic syndrome (TTS) is an exceedingly rare disease that causes facial ulceration, most commonly at the nasal ala. The overall incidence of TTS is not known, with less than 150 cases published in the literature.We searched the United States National Library of Medicine National Institutes of Health (PubMed) using the terms “Trigeminal Trophic Syndrome” and “TTS” as keywords. Publications in all languages were included if an English abstract was available. We reviewed 111 cases of TTS described in 75 publications from 1979 to 2021.Fourteen cases involved surgical reconstruction. Of these, the lesions completely healed in 7 cases (50%), recurred in 5 (36%), and were unspecified in 2 (14%). Reconstruction was completed in a 2 to 3-stage approach in 6 cases; of these, healing without recurrence was observed in 5 cases (83%). When donor tissue from the affected side was used as a basis for reconstruction, healing without recurrence was observed in 2 cases (50%). This is in comparison to the use of contralateral, sensate tissue in which there was healing without recurrence in all 3 cases (100%).The surgical management of TTS remains a topic of controversy. The rates of success remain comparable despite the use of various flap types. However, the use of contralateral, sensate flaps and a staged surgical approach appears to be effective based upon the best available evidence in the literature. Further prospective orretrospective controlled studies are necessary to make more reliable recommendations, though may be challenging given the rarity of TTS.

Abstract
Maxillary hypoplasia is common in patients with cleft lip and palate (CL/P), and its etiology is incompletely understood. The purpose of this study is to evaluate facial suture patency in patients with CL/P and maxillary hypoplasia. The authors hypothesize that patients with CL/P will demonstrate higher rates of premature midfacial suture fusion in comparison to unaffected controls. Skeletally mature patients with CL/P and midface hypoplasia were identified, along with a cohort of unaffected age- and sex-matched controls. High-resolution facial computed tomography scans were evaluated for the presence of facial suture fusion. Utilizing a previously published suture fusion grading scale, the facial sutures were classified as open, partially open, closed, or pathologically absent. Thirty-one CL/P patients with midface hypoplasia were identified, with age and sex-matched controls. The frequency of intermaxillary suture fusion did not differ between patients with CL/P and unaffected controls (P
> 0.05.) Pathologic absence of the midpalatal suture was more commonly present in patients with CL/ P and midface hypoplasia in comparison to unaffected controls (P < 0.05.) The role of midfacial sutures in the development of midfacial hypoplasia seen in CLP has not previously been studied or described. Our data show that the midpalatal suture is frequently pathologically absent in patients with CL/P and maxillary hypoplasia. The authors did not identify statistically significant differences in other midfacial sutures between patients with CL/P and controls, leading us to conclude that midfacial sutures may not play a key role in the development of midfacial hypoplasia.
The Use of Scapular Bone Flaps During Head-and-Neck Reconstruction: Functional, Orthopedic, and Quality of Life Analyses of Flap-Harvest-Related Deficits

Published: January 2022

Abstract:
The authors sought correlations between harvesting of the scapular bone tip free flap used for head-and-neck reconstruction and any shoulder function deficit, particularly at the level of the rotator cuff. The flap permits reconstruction of large and diverse regions of the head and neck, but long-term harvest morbidity has not been investigated extensively. The authors analyzed the clinical records of all patients who underwent head-and-neck reconstructions using free scapular tip flaps in our department over the past 5 years. The inclusion criteria were complete clinical and radiological documentation and follow-up for at least 12 months. Two populations, a surgical and control population, were analyzed. All patients in both populations underwent the simple shoulder test, an internationally validated self-administered test that highlights functional shoulder deficits, and 3 additional tests at orthopedic visits: the external rotation test, Patte test, and external rotation lag sign test. A head-and-neck cancer-specific questionnaire (University of Washington Quality of Life, version 4) was completed by the surgical patients. All statistical analyses were performed using Software IBM SPSS Statistics (IBM Corp., Armonk, NY).
A total of 19 patients met the inclusion criteria: 11 males (57.8%) and 8 females (42.2%) of mean age 60.9 years (range 23–75 years). In addition, 20 age-and sex-matched volunteers with no history of shoulder pathology were evaluated in terms of shoulder functionality. The average score on the simple shoulder test was 10.55 in the healthy population versus 8.31 in the study population (P < 0.001); in particular, shoulder strength differed between the groups. Similarly, the orthopedic examinations revealed clinically significant differences between the controls and patients on the Patte test and external rotation lag sign test (both P < 0.001), but not the external rotation test (P > 0.001). The mean University of Washington Quality of Life was 73.39; most patients reported good quality of life (52.6%), followed by very good (15.7%).
The free scapular bone tip flap is valuable for reconstruction of head-and-neck defects; the long and reliable vascularpedicle allows rapid patient mobilization. Morbidity was confined to small reductions in shoulder strength and external rotation, which do not affect quality of life.

Published: January 2022

Background:
Although metal stents have been widely used in the endoscopic step-up approach for necrotizing pancreatitis, the exact timing of transmural stent removal has not been well studied. Here, we report a novel strategy for stent removal and compare it with the conventional strategy.

Materials and Methods:
This retrospective, nested, case-control study analyzed all adult necrotizing pancreatitis patients who underwent endoscopic transmural necrosectomy (ETN). Clinical outcomes were compared between case group (a novel strategy in which the stents were removed during the last necrosectomy when the ETN endpoint was achieved) and 1:1 necrosis extent matched control group (the conventional strategy).

Results:
Baseline characteristics was comparable between case group (n=37) and control group (n=37). Three (8.1%) patients in case group and 1 (2.7%) patient in control group needed additional ETN after stent removal (P>0.05). Nearly all patients (case: 97.3%; control: 94.6%) achieved clinical success. There was no difference in disease-related (case: 40.5%; control: 37.8%) or stent-related (case: 27.0%; control: 16.2%) complications. Case group had a trend of shorter length of stent placement (median: 20.0 vs. 29.5 d, P>0.05).

Conclusions:
The novel strategy of transmural stent removal during last necrosectomy might be feasible which needed further validation. Compared with the convention strategy, the novel strategy avoids one endoscopy procedure and should be considered in clinical practice.
Proposal of a Novel Index of Abdominal Compliance and the Association With Postoperative Pain After Laparoscopic Inguinal Hernia Repair
Authors: Kinoshita Shoichi , Kawaguchi Chihiro , Takagi Tadataka , Ohyama Takao 
Published: January 2022

Background:
In laparoscopic surgery, low pneumoperitoneum pressure is reported to reduce pain, which suggests that easing abdominal expansion is crucial for less postoperative pain. However, although abdominal compliance (AC) is associated with the degree of abdominal expansion, the role of AC in pain by pneumoperitoneum is unknown. In this study, we devised a novel index as a surrogate of AC to evaluate the association between AC and postoperative pain in laparoscopic inguinal hernia repair.

Materials and Methods:
We reviewed 83 patients who underwent elective transabdominal preperitoneal repair from 2019 to 2021 at Heisei Memorial Hospital. Insufflation pressure was set to low pressure (8 mm Hg). The abdominal compliance index [ACI; insufflated intra-abdominal volume (L)/body surface area (m2)] was utilized to evaluate the association between AC and postoperative pain.

Results:
ACI was evaluated in 30 patients. Median ACI was 1.53 (1.00 to 2.48) L/m2. Although there was no difference in the average body constitution, the high ACI group (n=15) had significantly higher intra-abdominal volume at 8 mm Hg pressure, compared with the low ACI group (n=15) (3.1 vs. 2.1 L, P<0.0001). The high ACI group had significantly higher pain than the low ACI group on the day of surgery (2.0 vs. 1.0, P=0.006) and the day after (0.8 vs. 0.3, P=0.007). In addition, 46.7% of the patients in the high ACI group experienced pneumoperitoneum-associated pain, whereas patients in the low ACI group experienced incision pain only. Additional analgesics were administered in 53.3% of the high ACI group, compared with 33.3% in the low ACI group.

Conclusions:
AC was suggested to be a vital factor of postoperative pain after laparoscopic inguinal hernia repair. Patients with high AC may be susceptible to higher pain by pneumoperitoneum, even in low-pressure settings.

Published: January 2022

AbstractThe identification of associations between drugs and adverse drug events (ADEs) is crucial for drug safety surveil-lance. An increasing number of studies have revealed that children and seniors are susceptible to ADEs at the population level. However, the comprehensive explorations of age risks in drug-ADE pairs are still limited. The FDA Adverse Event Reporting System (FAERS) provides individual case reports, which can be used for quantifying different age risks. In this study, we developed a statistical computational framework to detect age group of patients who are susceptible to some ADEs after taking specific drugs. We adopted different Chi-squared tests and conducted disproportionality analysis to detect drug-ADE pairs with age differences. We analyzed 4,580,113 drug-ADE pairs in FAERS (2004 to 2018Q3) and identified 2,523 pairs with the highest age risk. Furthermore, we conducted a case study on statin-induced ADE in children and youth. The code and results are available at https://github.com/Zhizhen-Zhao/Age-Risk-Identification

AbstractThe recent epidemiological studies suggest that nearly one out of every 7 reproductive age couples face problem to conceive a child after trying for at least one year. Impaired fertility of the male partner is causative in approximately 50% of the infertile couples. However, the etiologies of large proportion of male infertility are still unclear. Our unpublished exome sequencing data identified several novel genes including TEX13B, which motivated us to further explore the role of TEX13B in male infertility in large infertile case control cohort. Hence in this study, we have examined the role of TEX13B in male infertility by whole gene sequencing 628 infertile and 427 control men and have demonstrated the functional role of Tex13b in spermatogonia GC1spg (GC1) cells. We identified 2 variants on TEX13B which are tightly associated with male infertility. TEX13B gene exclusively expressed in germ cells, but its molecular functions in germ cells are still unknown. Hence, we demonstrated the functional importance of Tex13b in GC1 cell line by genomic manipulation via CRISPR-Cas9 and mass spectrometry-based whole cell proteomics. The gene knock out in GC1 cell line clearly shows that Tex13b play an important role in germ cell growth and morphology. We demonstrate that Tex13b knockout or conditional overexpression in GC1 cells reprograms the metabolic status from an oxidative phosphorylation to glycolysis state and vice versa. In conclusion, our study clearly showed the importance of Tex13b in germ cells development and Its association with male infertility.

Published: January 2022

AbstractThe aim of this study is to construct and validate “physical literacy self-assessment questionnaire”(PLAQ)for Chinese students in grades 3-6. This study uses qualitative and quantitative methods to construct evaluation indicators of PL and determine the weights of each indicator. The 60 items of original PLAQ was based on literature review and interviews,and administered to 1179 primary students graded 3-6 in China. Exploratory factor analysis(EFA)and confirmatory factor analysis(CFA) are used to optimize the structure and verify the reliability and validity of the questionnaire. The model of PLAQ is composed of 4 first-level indicators, 10 second-level indicators and 35 third-level indicators. The results of EFA and CFA resulted in a 44-items, 4-factor questionnaire. EFA item loadings ranged from 0.558 to 0.896,and Cronbach’s alpha ranged from 0.818 to 0.892. The results of CFA show that the constructed model fits well, and PLAQ has good convergent validity and discriminative validity. The PLAQ appeared to be reliable and valid that can be used as an assessment tool for students in grades 3-6. PLAQ can be used as a guide for the development of PL. Additionally, PLAQ gives us a shared understanding about what PL is and how it can be developed by Chinese children. However, studies on the accuracy and generalizability of the PLAQ should be conducted to improve it in the future.

ABSTRACTBackgroundACEi/ARB medications have been hypothesized to have potential benefit in COVID-19. Despite concern for increased ACE-2 expression in some animal models, preclinical and observational-retrospective and uncontrolled trials suggested possible benefit. Two RCTs of the ARB losartan from University of Minnesota showed no benefit yet safety signals for losartan in outpatient and hospitalized COVID-19 patients. COVID MED, started early in the pandemic, also assessed losartan in a RCT in hospitalized patients with COVID-19.MethodsCOVID MED was a double-blinded, placebo-controlled, multicenter, platform randomized clinical trial (RCT). Hospitalized COVID-19 patients were randomized to receive standard care and hydroxychloroquine, lopinavir/ritonavir, losartan, or placebo. Hydroxychloroquine and lopinavir/ritonavir arms were discontinued after RCTs showed no benefit. We report data from the losartan arm compared to combined (lopinavir-ritonavir and placebo) and prespecified placebo-only controls. The primary endpoint, the mean COVID-19 Ordinal Severity Score (COSS) slope of change, was compared with the Student’s t-test. Slow enrollment prompted early termination.ResultsOf 448 screened patients, 15 (3.5%) were randomized/enrolled, 9 to receive losartan and 6 to receive control (lopinavir/ritonavir [N=2], placebo [N=4]); 1 patient who withdrew prior to study drug was excluded yielding 14 patients for analysis (losartan [N=9] vs. control [N=5] [lopinavir/ritonavir [N=2], placebo [N=3]]). Most baseline parameters were balanced. Treatment with losartan was not associated with a difference in mean COSS slope of change in comparison with combined control (p=0.4) or placebo-only control (p=0.05) (trend favoring placebo). 60-day mortality and overall AE and SAE rates were numerically but not significantly higher with losartan.ConclusionsIn this small blinded RCT in hospitalized COVID-19 patients, losartan did not improve outcome vs. control comparisons and was associated with adverse safety signals.

AbstractSystemic lupus erythematosus (SLE) is a complex and heterogeneous autoimmune disease involving multiple immune cells. A major hurdle to the elucidation of SLE pathogenesis is our limited understanding of dysregulated gene expression linked to various clinical statuses with a high cellular resolution. Here, we conducted a large-scale transcriptome study with 6,386 RNA sequencing data covering 27 immune cell types from 159 SLE and 89 healthy donors. We first profiled two distinct cell-type-specific transcriptomic signatures: disease-state and disease-activity signatures, reflecting disease establishment and exacerbation, respectively. We next identified candidate biological processes unique to each signature. This study suggested the clinical value of disease-activity signatures, which were associated with organ involvement and responses to therapeutic agents such as belimumab. However, disease-activity signatures were less enriched around SLE risk variants than disease-state signatures, suggesting that the genetic studies to date may not well capture clinically vital biology in SLE. Together, we identified comprehensive gene signatures of SLE, which will provide essential foundations for future genomic, genetic, and clinical studies.

AbstractBackgroundBackground incidence rates are critical in pharmacovigilance to facilitate identification of vaccine safety signals. We estimated background incidence rates of nine adverse events of special interest related to COVID-19 vaccines in Ontario, Canada.MethodsWe conducted a population-based retrospective observational study using linked health administrative databases for hospitalizations and emergency department visits among Ontario residents. We estimated incidence rates of Bell’s palsy, idiopathic thrombocytopenia, febrile convulsions, acute disseminated encephalomyelitis, myocarditis, pericarditis, Kawasaki disease, Guillain-Barré syndrome, and transverse myelitis during five pre-pandemic years (2015– 2019) and 2020.ResultsThe average annual population was 14 million across all age groups with 51% female. The pre-pandemic mean annual rates per 100,000 population during 2015–2019 were 43.9 for idiopathic thrombocytopenia, 27.8 for Bell’s palsy, 25.0 for febrile convulsions, 22.8 for acute disseminated encephalomyelitis, 11.3 for myocarditis/pericarditis, 8.6 for pericarditis, 2.9 for myocarditis, 1.9 for Guillain-Barré syndrome, 1.7 for transverse myelitis, and 1.6 for Kawasaki disease. Females had higher rates of acute disseminated encephalomyelitis and transverse myelitis while males had higher rates of myocarditis, pericarditis, and Guillain-Barré syndrome. Bell’s palsy, acute disseminated encephalomyelitis, and Guillain-Barré syndrome increased with age. The mean rates of myocarditis and/or pericarditis increased with age up to 79 years; males had higher rates than females: from 12–59 years for myocarditis and ≥12 years for pericarditis. Febrile convulsions and Kawasaki disease were predominantly childhood diseases and generally decreased with age.ConclusionsOur estimated background rates will permit estimating numbers of expected events for these conditions and facilitate detection of potential safety signals following COVID-19 vaccination.

AbstractIntroductionSudden cardiac death (SCD) is a devastating consequence often without antecedent expectation. Current risk stratification methods derived from baseline independently modeled risk factors are insufficient. Novel random forest machine learning (ML) approach incorporating time-dependent variables and complex interactions may improve SCD risk prediction.MethodsAtherosclerosis Risk in Communities (ARIC) study participants were followed for adjudicated SCD. ML models were compared to standard Poisson regression models for interval data, an approximation to Cox regression, with stepwise variable selection. Eighty-two time-varying variables (demographics, lifestyle factors, clinical characteristics, biomarkers, etc.) collected at four visits over 12 years (1987-98) were used as candidate predictors. Predictive accuracy was assessed by area under the receiver operating characteristic curve (AUC) through out-of-bag prediction for ML models and 5-fold cross validation for the Poisson regression models.ResultsOver a median follow-up time of 23.5 years, 583 SCD events occurred among 15,661 ARIC participants (mean age 54 years and 55% women). Compared to different Poisson regression models (AUC at 6-year ranges from 0.77-0.83), the ML model improved prediction (AUC at 6-year 0.89). Top predictors identified by ML model included prior coronary heart disease, which explained 47.9% of the total phenotypic variance, diabetes mellitus, hypertension, and T wave abnormality in any of leads I, aVL, or V6. Using the top ML predictors to select variables, the Poisson regression model AUC at 6-year was 0.77 suggesting that the non-linear dependencies and interactions captured by ML, are the main reasons for its improved prediction performance.ConclusionsApplying novel ML approach with time-varying predictors improves the prediction of SCD. Interactions of dynamic clinical characteristics are important for risk-stratifying SCD in the general population.
