Authors: Wali Razaz , Alhakami Amani , Alsafari Nada 
Published: June 2022

Aim: To evaluate the client satisfaction with a phone-based antenatal care consultation and identify the associated factors during the COVID-19 pandemic at King Abdul-Aziz Medical City, Primary Health Care Center Specialized Polyclinic during 2020. Method: The study was a cross-sectional, retrospective study conducted with pregnant women attending the maternity clinic at the Specialized Polyclinic, Primary Health Care Center at King Abdul-Aziz Medical City, Jeddah. A self-administered questionnaire was sent via a text message (short message service) to collect the data after signed written consent. Result: Of 279 pregnant women, 262 (93.9%) attended phone clinic appointments one to five times. The total satisfaction level score was 73.4 ± 6.5, indicating a high level of satisfaction with the phone clinics, and 252 (90.3%) reported a high level of satisfaction. There was a significant difference in the total score regarding education, occupation, husband’s occupation, smoking, gravidity, parity, menstruation, gestational age, pregnancy complication, number of phone clinics during pregnancy, number of attending clinics during pregnancy, visiting another health facility, and reason of visiting phone clinic ( p < 0.0001, p < 0.0001, p < 0.0001, p = 0.015, p = 0.033, p < 0.0001, p < 0.0001, p = 0.027, p = 0.001, p < 0.0001, and p = 0.002). Conclusion: The study indicated a high level of satisfaction with the antenatal telephone clinics during the pandemic, which supports the trend of transition in the direction of the digitalization of antenatal care.
Seating in Doctors’ Waiting Rooms: Has COVID-19 Changed Our Choices?
Authors: Devlin Ann Sloan 
Published: June 2022

Objective: This study investigates preference for five different seating arrangements (e.g., rows, clusters) in a doctor’s office waiting room, whether these reduce stress and improve judgments of medical care, and how such choices may have changed over the pandemic (2013 vs. 2021). Background: What is called the doctor’s office layout, with chairs lining the perimeter of the waiting room, is criticized by designers, yet little empirical evidence exists to support that assessment. Method: Data collected in 2013 and 2021 used sketches of five different seating arrangements; people saw just one of these. The study examined the effect of time and seating arrangement on anxiety, need for privacy, situational awareness, evaluation of the environment, and perception of the doctor. Results: There was no significant impact of the seating arrangement on any of the dependent variables, but ratings were higher for situational awareness, need for privacy, evaluation of the environment, and aspects related to the physician in 2021. In addition, seating preferences favored end, not middle seats, and chair selections with the chair back to a wall. Conclusion: In this study, no evidence exists that the doctor’s office layout is less preferred than four other seating arrangements, but seat choice shows people prefer end seats (not middle seats) across arrangements. The doctor’s office layout may offer a supportive familiarity to people; also, given the percentage of people who visit the doctor unaccompanied, layouts designed to encourage social interaction may not always be appropriate.

Published: June 2022

Background Asymmetry between the transverse sinuses (TS) is quite common. We sought to test the possible hypothesis that certain anatomical features – namely, occipital lobe bending, Gibraltar sign of superior sagittal sinus groove (SSS) and jugular foramen (JF) dimensions – can predict dominance of the transverse sinuses on routine axial T1- and T2-weighted images. Materials and methods One hundred consecutively acquired combined MRI-MRV studies of brain were reviewed. On non-contrast axial T1WI, each reviewer assessed the occipital lobe bending, and Gibraltar sign of SSS groove; on axial T2-weighted images, JF dimensions were measured. TS cross-sectional area was measured on non-contrast sagittal 2-dimensional phase contrast MRV images and served as the reference standard. Results Of the 51 subjects with right-dominant TS, 37 had occipital bending to the right side and 35 showed sloping of the Gibraltar sign to right side. Of the 18 subjects with left dominant TS, 10 had occipital bending to left side and 13 showed left-sided sloping of the Gibraltar sign. Of the 31 subjects with co-dominant TS, 15 had no occipital bending and 20 showed no sloping of the Gibraltar sign. Mean right and left JF dimensions were higher in the right and left dominant TS respectively with no significant differences in patients with co-dominant sinus ( p < 0.02). Conclusion Right occipital bending had a good association with right TS dominance. The other two parameters- Gibraltar sign of superior sagittal sinus groove and jugular foramen dimensions – did not have a very good association with respect to TS dominance.

Published: June 2022

Objectives: To determine the role of the male sex as a risk factor for coronavirus disease deaths in Sao Paulo and to what extent socioeconomic vulnerability and individual health issues can interfere in such risk. Methods: The primary cause of death, age, sex, comorbidities, and code of the Human Development Units of the residence of 37,583 individuals in Sao Paulo, Brazil, were obtained from the records on confirmed coronavirus disease resident hospitalizations of the city of Sao Paulo from the National Influenza Surveillance Information System. A social vulnerability index was assigned to each Human Development Unit. Using “death” as the outcome variable and sex, admission to the intensive care unit, obesity, renal and heart diseases, diabetes, and social vulnerability as confounders, the odds of death for males and females were compared via logistic regression. Results: The odds of death for males were 1.242 (confidence interval 95% = 1.237, 1.247) times the corresponding odds for females with the same values for all confounders. We estimated the odds of death for patients living in regions with high social vulnerability as 2.243 (CI 95% = 2.151, 2.339) times the corresponding odds of patients living in regions with very low social vulnerability with the same values of the remaining variables. Conclusion: The male:female death ratio by severe acute respiratory syndrome coronavirus 2 infection in Sao Paulo cannot be attributed only to comorbidities or social vulnerabilities. Our results suggest that the male sex is an independent biological risk factor for coronavirus disease death. Besides sex-specific factors, further research should focus on crucial biological factors in male sex coronavirus disease mortality.

Authors: Goto Ryohei , Haruta Junji , Ozone Sachiko 
Published: June 2022

Introduction/Objectives: We aimed to verify whether a sense of community scale developed for hospital wards can be applied to hospitals. Methods: A cross-sectional study was conducted using a self-administered questionnaire between July and October 2018 in 3 hospitals in Japan. The subjects were staff members working in these hospitals who provide direct medical or administrative services to patients and their families. The questionnaire inquired about the participants’ basic attributes and workplace satisfaction, and included the sense of community scale and the Japanese version of the Assessment of Interprofessional Team Collaboration Scale-II. We evaluated the scale’s structural validity, internal consistency, and hypothesis testing for construct validity. Results: Of 826 eligible staff members, 539 were included in the analysis. Mean age was 40.4 years and 77.4% were female. Exploratory factor analysis showed that 24 of the 28 items in the sense of community scale could be categorized under 3 factors. Confirmatory factor analysis demonstrated a goodness of fit index of 0.794, adjusted goodness of fit index of 0.752, comparative fit index of 0.885 and root mean square error of approximation of 0.092. Cronbach’s α for score in the sense of community scale was high (.96). Participants who reported high workplace satisfaction had significantly higher scores in the sense of community scale than those who indicated low workplace satisfaction ( P < .001). Conclusions: We verified the reliability and validity of the Japanese version of the sense of community scale, which was originally developed for hospital wards, for the community in hospitals. With further verification, we hope the scale will be useful for evaluating the sense of community in hospitals.
Shortening the Return-to-Play Times in Elite Athletes With Unstable Isolated Lisfranc Ligament Injuries Using a Knotless Interosseous Suture Button: Case Series and Literature Review
Authors: Sullivan Martin , Peckston Dane , Alpuerto Bernardino 
Published: June 2022

Background: Isolated unstable Lisfranc ligament injuries in elite athletes are associated with a lengthy period of rehabilitation and prolonged absence from competition. Purpose: To assess the efficacy of a knotless, interosseous suture button system for repairing isolated unstable ligamentous Lisfranc injuries and its capacity to allow accelerated rehabilitation with earlier weightbearing and return-to-play times in elite athletes. Study Design: Case series; Level of evidence, 4. Methods: The authors retrospectively reviewed data from a prospectively compiled database for elite athletes treated by a single surgeon. All included patients had clinical and magnetic resonance imaging evidence of an unstable isolated complete ligamentous Lisfranc injury requiring surgical reduction and stabilization. All patients underwent surgery using a knotless interosseous suture button to achieve stabilization, followed by a standardized postoperative regimen involving full weightbearing at 4 weeks, and all had a minimum postoperative follow-up of 2 years. Results: Included were 12 patients: 7 National Rugby League (NRL) players, 2 professional dancers, 1 Olympic gymnast, 1 professional wakeboarder, and 1 professional NRL referee. The mean age of the patients was 21.1 years (range, 16-34 years). Ten patients underwent acute surgical stabilization within 3 weeks of the injury, and 2 patients sustained chronic isolated Lisfranc instability that was initially treated nonoperatively. All athletes were able to return to full weightbearing by 4 weeks postoperatively, successfully returned to training by 9 to 12 weeks, and returned to full competition by 12 to 16 weeks. No major complications were reported. Conclusion: Knotless interosseous suture button stabilization was a reliable treatment option for both acute and chronic isolated ligamentous Lisfranc injuries in these elite athletes. This technique does not require hardware removal, allows early weightbearing with accelerated rehabilitation, and may shorten the return-to-play interval.

Published: June 2022

Background: Rebuilding the strength of the quadriceps as soon as possible after total knee replacement (TKR) is important so as to restore gait stability. To date, there are no standard postoperative strength training programs during the early recovery stage after TKR. Purpose: To compare the therapeutic effects between isokinetic and isotonic strengthening in patients after TKR. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: From April 2018 to August 2020, 37 patients met the inclusion criteria and were randomly assigned to perform either 4-week isokinetic or isotonic strength training programs. Other components of the rehabilitation program were kept the same between the 2 groups. All cases were evaluated by the Timed Up and Go (TUG) test, peak torque of knee extension and flexion (60 and 120 deg/s), 36-item Short Form Health Survey (SF-36), and Western Ontario and McMaster Universities Arthritis Index (WOMAC). Results: After undergoing a 4-week strength training regimen, significant improvements in the TUG test were noted in both groups; however, the time improvement in the isotonic group did not reach the minimal detectable change. All peak torque measurements improved in the isokinetic group but not in the isotonic group for knee flexion at 60 deg/s. The pain subdomain, physical domain, mental domain, total SF-36 score, and WOMAC index all improved significantly in both groups after training. Both training groups improved significantly in peak torque of knee strength, TUG test, and functional scores, but the differences between isokinetic and isotonic training were not statistically significant. Conclusion: The study findings showed that a 4-week strengthening exercise program in the early postoperative stage, involving either isokinetic or isotonic training, resulted in significant improvements in patients undergoing TKR. Registration: NCT02938416 ( ClinicalTrials.gov identifier).

Published: June 2022

Objective: The aim of this study was to assess the topography of the femoral and popliteal vessels focusing mainly on the venous variants, in patients with chronic venous disease (CVD). Materials and Methods: Duplex ultrasonography (DUS) was performed on 200 patients with varicose veins (VVs) and 253 patients with postthrombotic syndrome (PTS). In addition, an anatomical dissection was performed on 30 amputated lower extremities, without signs of CVD. Results: Duplication of the femoral vein (FV) was found in 14% of patients with VVs. Multiple FV trunks were identified in 42% of patients with PTS. One patient had a developmental anomaly with a hypoplastic FV and dilated deep FV. Two trunks of the popliteal vein (PV) below the knee level were detected in 83.3% of cases during anatomical dissection, in 87.5% of cases in patients with VVs, and in 90.1% of cases in PTS subjects during DUS. In 98.2% of cases, popliteal artery (PA) had a typical bifurcation. One patient was presented with a duplication of PA above the level of the knee. In 1.8% of cases, the PA was divided into an anterior tibial and peroneal artery. Conclusion: This study found variant anatomy in the FV and PV, which is frequent, with major changes occurring in patients with PTS. Variant anatomy of the PA was also found and is considered uncommon, occurring in less than 2% of cases.
The Relationship Between Cognitive Variables for Academic and Clinical Success After the Completion of One Year of Courses for Diagnostic Medical Sonography and Radiography Students
Authors: Miller Elena 
Published: June 2022

Objective: Most health care programs have competitive entry and selective admission procedures. The purpose of this study was to investigate the relationship between cognitive variables such as the Test of Essential Academic Skills (TEAS) composite scores, the preprogram academic grade point average (GPA), as well as clinical GPA for diagnostic medical sonography (DMS) or radiography (RT) students. Materials and Methods: The participants of this study were 26 imaging students. The convenient sample included 10 DMS and 16 RT students, enrolled in an Associate Degree in Applied Sciences program, within a community college. The student’s program success was examined over a period of one academic year. Results: The analysis of the findings determined that a significant relationship existed between some of the cognitive variables such as the TEAS composite scores, academics, as well as the clinical success for the DMS students. However, these RT students did not show the same outcome. In addition, there was no significant relationship between preprogram GPA and academic as well as clinical success, for either educational program. Conclusion: The results of this study provide empirical evidence that a strong relationship may exist between the TEAS composite scores, academics, as well as clinical success for the DMS students. This is an important finding that may support the use of the TEAS test, as part of the admission process, for other DMS programs.

Published: June 2022

BackgroundThere are phenotypic differences in asthma in males and females. Differences in lung function between the sexes at the peak lung function level in young adulthood are so far not directly addressed. The aim of the present study was to assess lung function in early adulthood in males and females depending on asthma onset and remission.MethodsParticipants were included from the population-based birth cohort BAMSE and classified as having: never asthma, childhood asthma in remission, adolescent onset asthma or persistent asthma. Pre- and post-bronchodilator lung function (in Z-score) and lung clearance index (LCI) were measured at age 24 years. Lung function was compared stratified for sex between the never asthma and asthma groups univariately and in multiple linear regression analyses adjusted for maternal and paternal asthma, maternal smoking during pregnancy, secondary smoking, daily smoking, early respiratory syncytial virus infection, traffic pollution, childhood allergic sensitisation, and body mass index at age 24 years.ResultsAll asthma phenotypes were associated with a lower forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) post-bronchodilation at 24 years. This was most pronounced in males with persistent asthma compared to males with never asthma (regression coefficient: −0.503; 95% CI: −0.708– −0.298). Childhood asthma (in remission or persistent) was associated with a lower FEV1. After adjustment, the associations remained significant for males. For females, the significant associations with lower FEV1and FEV1/FVC remained only for subjects with asthma in remission. Persistent asthma was associated with higher LCI in females.ConclusionsIn females, in contrast to males, the association between asthma and lower lung function was attenuated after adjustment for known risk factors.

Abstract
Background
Up until now, evidence pertaining to the short-term effects of fine particulate matter (PM2.5) in cardiovascular diseases (CVD) is scarce in China. In this study, we aim to estimate the association between short-term exposure to PM2.5 and hospitalizations for total and cause-specific CVD in Lanzhou of China.

Methods
Daily counts of cardiovascular admissions were obtained from three large general hospitals in Lanzhou, China between 2014 and 2019. Air quality and meteorological data were obtained from the monitoring stations nearest to the admitting hospitals. We utilized Quasi-Poisson time-series regressions with distributed lag nonlinear models (DLNM) to assess the association between PM2.5 and CVD admitted in the three general hospitals. A stratified analysis was also conducted for age, sex, and disease subcategories.

Results
PM2.5 was positively correlated with daily admissions for total or other cause-specific CVD under different lag patterns. For every 10 μg/m3 increase in the PM2.5 concentration, the relative risk of daily admissions for total CVD, ischemic heart disease (IHD), heart rhythm disturbances (HRD), heart failure (HF), and cerebrovascular disease (CD) was: 1.011 [95% confidence interval (CI), 1.001–1.020] in lag01; 1.020 (95% CI 1.004–1.036) in lag07; 1.013 (95% CI 1.001–1.026) in lag7; 1.018 (95% CI 1.005–1.038) in lag1; and 1.007 (95% CI 1.001–1.018) in lag1. Both low and high temperatures increased the risk of cardiovascular hospitalization. No differences were found after stratification by gender and age. We found an almost linear relationship between the exposure to PM2.5 and cause-specific CVD admissions with no threshold effect. Males as well as the elderly, aged ≥ 65 years, were more vulnerable to PM 2.5 exposure.

Conclusions
Our results have demonstrated that PM2.5 has adverse impacts on cardiovascular hospitalizations in Lanzhou, especially on IHD.
The time cost of saving money: detouring and connecting time losses in the virtually interlined European airport network
Authors: Meire Sarah , Derudder Ben 
Published: June 2022

AbstractVirtual interlining, the use of actively marketed self-connecting flight itineraries, is often assumed to be a money-saving air travel strategy. Earlier research on this topic broadly confirmed the money-saving character of virtual interlining, but to date non-monetary costs associated with this price advantage have not yet been systematically examined. In this paper, we address this lacuna by juxtaposing the price advantage of virtual interlining with the potential time costs for the case of indirect flight itineraries in the European airport network. Focusing on those markets where the cheapest virtually interlined itinerary renders a price advantage over its indirect traditional counterpart, we analyse the time cost from two complementary perspectives: (1) connecting time and (2) detour factor. To this end, we query Kiwi.com’s Tequila platform to obtain data on all available flight itineraries in the first week of August, October and December 2019. Based on a series of sign tests, we reveal the time costs of saving money: while virtually interlined itineraries render a price advantage compared to their indirect traditional counterparts, they come with a significantly larger connecting time and detour factor. We reflect on possible explanations, and highlight a number of avenues for future research.
