Sarcopenia and Its Association With Change of Bone Mineral Density and Functional Outcome in Old-Aged Hip Arthroplasty Patients

Aim This study aimed to investigate the relationship between sarcopenia and change in bone mineral density (BMD) and functional outcome in hip arthroplasty patients. Methods: Among the 221 patients who had undergone hip arthroplasty, 147 patients were enrolled. All patients were divided into 2 groups according to presence of sarcopenia. Bone mineral density (BMD) at hospitalization and 1-year after surgery and Barthel index was measured at the time of before injury, hospitalization, 3 months and 1-year after surgery. Results: BMD at hospitalization showed . 627 ± . 082 (g/cm2) in Sarcopenia and . 726 ± . 059 (g/cm2) in Non-sarcopenia at femur (total) site (P < .001), . 531 ± . 085 (g/cm2) vs . 629 ± . 057 (g/cm2) at femur neck site (P=.002), . 715 ± . 084 (g/cm2) vs . 807 ± . 058 (g/cm2) at lumbar (L1-L4) site (P < .001). BMD at 1-year follow-up period, Sarcopenia showed . 626 ± . 082 (g/cm2) and Non-sarcopenia showed . 725 ± . 060 (g/cm2) at femur (total) site (P < .001), . 530 ± . 085 (g/cm2) vs . 629 ± . 058 (g/cm2) at femur neck site (P < .001), . 715 ± . 084 (g/cm2) vs . 806 ± . 058 (g/cm2) at lumbar (L1-L4) site (P < .001). Change of BMD showed −. 01 ± . 25% for Sarcopenia and −. 15 ± . 47% for Non-sarcopenia in femur (total) site (P=.089), −. 08 ± . 63% vs −. 01 ± 1.01% in femur neck site (P = .058), . 00 ± . 09% vs −. 12 ± . 33% for each group in lumbar (L1-L4) site (P = .052). Barthel index score showed 79.94 ± 5.66 for Sarcopenia and 84.74 ± 5.36 for Non-sarcopenia at pre-injury status (P < .001), 33.89 ± 4.94 vs 33.87 ± 5.36 at the time of hospitalization (P = .977), 57.42 ± 7.19 vs 60.06 ± 5.39 at 3 months follow up (P = .015), 73.86 ± 5.94 vs 80.71 ± 4.81 for each group at 1-year follow up (P < .001). Conclusions: Our study found that the sarcopenia showed lower BMD than the non-sarcopenia, but there was no significant difference of BMD change in the follow-up period. In addition, the sarcopenia showed poor functional results at all points except at the time of hospitalization.
COVID-19-Related Anxiety Symptoms among Quarantined Adolescents and Its Impact on Sleep Pattern Changes and Somatic Symptoms

Background: Home-quarantine due to COVID-19 may have negative psychological effects on vulnerable sub-groups such as children and adolescents. We aimed to explore the prevalence of anxiety among adolescents who were in home-quarantine and its impact on onset of sleep disturbance and somatic symptoms, and on the level of agreement between adolescent and parent perceptions. Methods: Five hundred adolescents (ages 10–17) and 500 parents participated in the study. Adolescents filled out PROMIS Anxiety, PROMIS Sleep Disturbance, and PHQ-15 Physical-Symptom forms, while their parents completed proxy questionnaires containing the same domains. Results: 38% of the adolescents reported experiencing anxiety during home-quarantine period, 29% suffered from sleep disturbance, and 48% reported somatic symptoms. Addition of one day in home-quarantine was significantly associated with sleep disturbance (OR = 3.78, 95%CI: 1.09–8.45) and somatic symptoms (OR = 1.80, 95%CI: 1.01–3.08); female gender was associated with increased risk for somatic symptoms (OR = 2.15, 95%CI: 1.07–4.55); poor agreement in levels of anxiety, sleep disturbance and somatic symptoms was found between adolescent and parent reports (ICCs of 0.197–0.262). Discussion: Total isolation from household members during home-quarantine may cause anxiety, sleep disturbance, and somatization among adolescents. Achieving the appropriate balance between infection control and mitigation of the potential adverse psychological effect of home-quarantine among children and adolescents should be immediate priorities for policymakers.
Correlation between Brightness Variability and Spectral Index Variability for Fermi Blazars

In this work, the γ-ray photon flux, photon spectral index (α ph), variability index ( logV.I. ), and the synchrotron peak frequency ( logνp ) are compiled for 851 common blazars from the 3FGL and 4FGL catalogs and Fan et al. to investigate variability properties for Fermi blazars. Our calculations and analyses reach following results: (1) the averaged luminosity, spectral index, and variability index of FSRQs are higher than those of BL Lacs for the whole sample. (2) It is found that the spectral index variation is closely anti-correlated with the luminosity variation implying that the spectrum becomes harder when the source becomes brighter in the γ-ray band. (3) Positive correlations are found between the photon spectral index and both γ-ray luminosity and variability index ( logV.I. ) for the whole sample, but anti-correlations are found in the two correlations for FSRQs. For BL Lac subclass, there is a marginal anti-correlation between the photon spectral index and both γ-ray luminosity, and a positive correlation between the photon spectral index and the variability index ( logV.I. ). We think those two positive correlations found for the whole sample are apparent. (4) We adopted the SVM machine learning method to separate BL Lacs and FSRQs in the αphversuslogLγ and αphversuslogV.I. plots and proposed that a BCU is an FSRQ candidate if it satisfies logV.I. >−10. 119α+24.855 , or αph>−0. 048logLγ+4.498 , otherwise, it is a BL Lac candidate. Our classification results are quite consistent with those by Kang et al (2019).
Postharvest behavior and chilling injury in avocado (Persea americana Mill) fruit cv. Hass treated with 1-methylcyclopropene, ethylene, and intermittent warming

Persea americana, cv. Hass has become an important crop in Colombia due to increased exports to European markets; however, the avocado is a climacteric fruit sensitive to chilling injury, reducing its shelf-life and affecting commercialization abroad. This research aimed to evaluate the effect of 1-methylcyclopropene, ethylene, and intermittent warming on chilling injury and postharvest behavior of avocado cv. Hass. Five treatments were evaluated: Control; Intermittent warming cycles of 4 days at 2 °C + 1 day at 18 °C; Intermittent warming cycles of 7 days at 2 °C + 1 day at 18 °C; 1-methylcyclopropene, and ethylene. The fruits were stored for 29 days at 2 °C and then up to 14 days in the shelf-life period. The intermittent warming treatment 4-days cycles reduced chilling injuries. However, this treatment increased weight loss, respiration, epidermal color index, and electrolyte leakage during the storage period at 2 °C. Intermittent warming showed that Hass avocado fruit ripens faster, regardless of the application of ethylene in the shelf-life period. The results indicated that intermittent warming reduced the chilling injury, the treatment with 1-methylcyclopropene delayed ripening but it is not recommended for avocado cv. Hass when stored at 2 °C because the chilling injury is not reduced.
Anticipatory marking of (non-corrective) contrastive focus by the Initial Rise in French

This study addresses tonal marking of non-corrective contrastive focus in French. Speakers read aloud sentences composed of two parallel clauses, where the structure of the post-verbal constituent under focus was varied by the presence or absence in the second clause of the final adjective appearing in the first clause (signaling Noun-focus or NP-focus, respectively). This way, we were able to test whether the Initial Rise (i.e., LHi) is a marker of the span of an upcoming non-corrective contrast in the second clause. We posited that French speakers mark contrast tonally in the first and/or second clause. Corroborating previous findings, we found that a faster speech rate is associated with fewer Initial Rises. More importantly, an Initial Rise occurs on the direct object of the first clause more often in narrow focus. Additionally, the height of the Initial Rise peak does not depend on focus structure. These results suggest that anticipatory use of the Initial Rise may signal an upcoming contrast and reveals additional complexity in the tonal encoding of the left edge of a contrastively focused constituent.
Social Media Policies in U.S. Television Newsrooms: Changes over Time

This study analyzes survey data, gathered in 2014 and 2020, regarding local television newsrooms’ social media policies (SMPs). The purpose of the study is to explore changes to these policies. As part of this inquiry, the researchers investigate if and in which ways newsroom SMPs are evolving in four areas: journalists’ professional and personal social media activities; social media sources and content; audience complaints; and ownership of on-air talents’ accounts. The researchers found a significant increase of guidelines regarding what is and is not appropriate on the professional and personal social media of journalists, with little distinction made between these types of accounts. Although newsrooms have implemented policies to articulate what is appropriate conduct and a majority have revised policies, those guidelines don't always address the contemporary issues journalists face, specifically online threats and verification of user-generated content. The researchers found an increasing percentage of news outlets retain ownership of on-air talents’ professional accounts.
Tourist interaction and satisfaction with the chatbot evokes pre-visit destination image formation? A case study

ABSTRACT Destinations increasingly use chatbots in the management and communication with tourists. This study analyzes the mediating effect of chatbot usage satisfaction on forming the destination’s image. As a case study, we use the Chabot “Victoria la Malagueña,” Spain. Confirmatory factor analysis and structural equations were necessary to identify the relationships between the constructs. The results show that informativeness and empathy are the main attributes that influence user satisfaction and mediate forming a destination image. The study has managerial implications and provides destination management organizations with practical information for creating chatbots.
Business improvement districts, class turf war and the strategic weaponisation of class monopoly rent

Business improvement districts (BIDs) are understood as a proactive response by locally dependent property owners and businesses aimed at attracting capital investment and consumers back to the central city at a time of increasingly gutted public sector resources. BIDs have yet to be explicitly examined as a form of rent-seeking, even though the primary motivation for property owners to self-impose additional taxes for implementing ‘clean and safe’ programmes is rent. In this context, the self-imposed tax is treated as a speculative investment that will hopefully yield a return in the form of enhanced profit for businesses and rents for landowners. As such, we conceptualise BIDs as not only a form of rent-seeking, but an alliance of private-sector actors engaged in the collaborative and strategic mobilisation of class monopoly rent as a weapon against all perceived barriers to profitability. Based on evidence from Seattle, Washington, the paper deepens our understanding of BIDs by linking this phenomenon to the spatial dynamics of rent within the contemporary neoliberal city and concludes by discussing the implications for what BIDs reveal about class monopoly rent in particular, the kind of class conflict this form of rent configures and its role within wider processes of neoliberal urbanisation.
Increased Knowledge of Adult-Onset Dystonia Amongst Medical Students via Brief Video Education: A Systematic Review and Cohort Study

Most doctors have limited knowledge of dystonia, a movement disorder that can affect people of all ages; this contributes to diagnostic delay and poor quality of life. We investigated whether a brief educational intervention could improve knowledge of dystonia amongst medical students. We conducted a systematic review on undergraduate knowledge of dystonia and created an eight-minute video on the condition. We invited medical students at the University of Leeds, UK, to answer 15 multiple choice questions before and immediately after watching the video, and again one month later. Only one previous study specifically assessed medical students’ knowledge of dystonia whilst five others tested their knowledge of movement disorders, or neurology generally, with some questions on dystonia. Of the University of Leeds medical students, 87 (100%), 77 (89%) and 40 (46%) completed the baseline, immediate-recall and delayed-recall questionnaires, respectively. The mean score for students who completed all three questionnaires increased from 7.7 (out of 15) to 12.5 on the immediate-recall questionnaire (p < 0.001), and to 10.1 on the delayed-recall questionnaire (p < 0.001). At baseline, 76% of students rated their confidence in recognising dystonia as low. After watching the video, 78% rated their confidence as a high, and none rated it low. A brief video improved their knowledge substantially, with sustained effects. This method could be incorporated into medical curricula to reduce diagnostic delays.
Effect of Structured Teaching Programme on Prevention of Sexually Transmitted Infections in Terms of Knowledge and Attitude among Teachers of Rohtak (Haryana)

A pre-experimental study was conducted to evaluate the effectiveness of structured teaching programme (STP) on prevention of Sexually transmitted infections (STIs) in terms of knowledge and attitude among teachers of selected School at Rohtak, Haryana. A total of 40 teachers were selected by Convenience sampling technique. A structured questionnaire was used to collect the data. The mean pre-test knowledge score was 18.15 which increased to 28.32 in post-test and the mean pre-test attitude score was 106.35 which increased to 118.6 in post-test and there was significant association of post-test knowledge scores of subjects with selected variables such as type of family and previous information regarding STIs but there was partial significant relationship of knowledge of school teachers with selected variables. The study concludes that STP was significantly effective in enhancing the knowledge and change in attitude of subjects irrespective of sample characteristics regarding prevention of STIs.
PREVALENCE OF CERVICAL ABRASION IN TERTIARY CARE CENTER OF CHITWAN

Background: Cervical abrasion is defined as the loss of tooth substance that occurs in the absence of carious mechanism at cementoenamel junction of a tooth. This type of lesion can cause discommoding effects in dental health. The aim of the study was to assess the prevalence of cervical abrasion among general population in Chitwan and to relate the find­ing to probable etiology, thereby developing an etiological hypothesis that can be beneficial during treatment. Methods: The study was carried out between August 2019 and October 2019 in 500 adults who attended the department of Conservative Dentistry and Endodontics, COMS-TH. A proforma con­sisting of demographic data, type of diet and oral hygiene practices was used for the data col­lection and each patient went through a clinical examination as well. The statistical analysis was performed using SPSS. Descriptive analysis was performed and Chi-square test of association was done. Results: Total prevalence of cervical abrasion in the study population was 10.4%. A statistically sig­nificant relationship was observed between cervical abrasion, gender, age, toothbrush frequency, method of tooth brushing and type of toothbrush employed. The study affirmed that population with cervical abrasion had hypersensitivity. Conclusions: The prevalence of cervical abrasions was seen to increase with age, frequency of toothbrushing, faulty method of toothbrushing and use of inappropriate type of toothbrush. Hence, it is advocated that dental professionals guide people on correct brushing technique and use of appropriate type of toothbrush to avoid and prevent this problem from worsening.

Representation of Work-Related Trip Patterns in Household and Commercial Travel Surveys

This paper considers which work-related trip patterns are included in household travel surveys and which in commercial travel surveys and if there are certain patterns that are distinctly underrepresented in either one. The study is structured as a comparison between data from a household travel survey and data from a commercial travel survey. Both surveys were conducted in Germany and within close temporal proximity. We applied cluster analysis to identify differences in the data and identify work-related travel patterns. The results show that work-related travel patterns are quite complex. Although some patterns are covered in both surveys, mobile workers’ travel patterns in particular are not represented well in the household travel survey. Furthermore, our analysis shows that not all commercial trips are generated by motorized vehicles and a considerable share of work-related trips are undertaken using public transport or active modes of transport that are not covered by the commercial travel survey. The results indicate that researchers and transport planners creating travel demand models need to pay more attention to work-related travel behavior and acknowledge that depending on the area of study, traditional household travel surveys may not provide a complete sample of the population; however, simply adding data on commercial trips from commercial travel demand models to data from household travel surveys does not provide a complete picture of work-related travel either.
Analysis and Design of a Discrete-Time Delta-Sigma Modulator Using a Cascoded Floating-Inverter-Based Dynamic Amplifier

This article presents a delta–sigma modulator (DSM) using a cascoded floating-inverter-based dynamic amplifier. The proposed cascoded dynamic amplifier achieves more than 50-dB dc gain while maintaining an HD3 of better than –110 dBc for signal swings less than <inline-formula> <tex-math notation="LaTeX">$300~\mathrm {mV_{ppd}}$ </tex-math></inline-formula>. Compared to the previously reported two-stage floating inverter amplifier (FIA), the cascoded FIA has a lower and a process invariant input-referred noise, making it an ideal choice for high-resolution ADCs. We also show that, when such a single-stage dynamic amplifier, which has a time-varying transconductance, is used in closed-loop switched-capacitor circuits, the settling bandwidth depends on the average transconductance <inline-formula> <tex-math notation="LaTeX">$G_{m,\rm avg}$ </tex-math></inline-formula> during the settling interval. A detailed analysis reveals that, when the floating inverter structure operates in weak inversion for most of the time (which is the power-efficient way to bias the amplifier), this average transconductance depends strongly on the reservoir capacitance value and only weakly on the transistor dimensions. Besides, it is less sensitive to temperature variations, unlike the transconductance of a conventional OTA biased in weak inversion. We also quantitatively derive and show that the cascoded FIA is more power-efficient than a conventional static-current biased operational transconductance amplifier. Using the cascoded FIA, a discrete-time DSM has been designed and fabricated in a 180-nm CMOS process. The modulator runs at 3.072 MHz while consuming 189 <inline-formula> <tex-math notation="LaTeX">$\mu \text{A}$ </tex-math></inline-formula> from a 1.8-V supply. In a bandwidth of 24 kHz, the measured SNR/SNDR/SFDR is 96.4/96.2/114 dB, respectively.
Evaluation of the performance of a dynamic wave climate ensemble simulated using with EURO‐CORDEX winds in the Black Sea and Sea of Azov

This study evaluates the performance of a dynamic ensemble of wave climate simulations for the Black Sea. The ensemble members (and ensemble means) are evaluated for the historical period (1979–2005). The spectral wave model (simulating waves nearshore [SWAN]) was forced with eight Coupled Model Intercomparison Project Phase 5 (CMIP5) based Regional Climate Models (RCMs) wind fields to obtain each of the eight ensemble members. The RCM‐forcings used belongs to the European branch of the Coordinated Regional Downscaling Experiment (EURO‐CORDEX). The ensemble members' historical wave climate is thoroughly compared against the ERA5 reanalysis, in situ observations, and altimeter measurements. In addition to the individual evaluation of ensemble members, the results for the 8‐member ensemble mean are also examined. The performance of the ensemble members in reproducing the mean and extreme significant wave heights, mean wave periods, and mean wave directions is found to be good, with differences generally between +25 and −15% in comparison to ERA5. Differences between +10% and −30% were found for the comparison with altimeter measurements. We conclude that the ensemble better represents the wave climate of the Black Sea, than its individual members. The 8‐member ensemble provides a more balanced dataset for the Black Sea wave climate and a better representation of the associated uncertainty. Thus, further wave climate projections for the Black Sea should rely on the use of an ensemble.
Evaluating the Psychometric Properties of a Proposed Farsi Version of the Interpersonal Reactivity Index Using Item Response Theory

Purpose Although researchers have examined empathy among many populations worldwide, investigations of empathy among Farsi-speakers are limited. The purpose of this study is to evaluate the psychometric properties of the Interpersonal Reactivity Index (IRI) for Farsi-speakers (IRI-Farsi). Methods After translating, we explored psychometric properties of the IRI-Farsi with exploratory factor analysis and item response theory using a sample of Iranians (N = 517). Results The IRI-Farsi appeared to exhibit a four-factor structure and acceptable item properties within each subscale. Moreover, the IRI-Farsi rating scale categories were generally ordered and distinct with emotion-triggering items as easier to endorse compared to more complex cognitively aroused statements. Conclusions Results support using the IRI to measure dispositional empathy in mainland Iran. Social work researchers can use these results to inform research and practice related to empathy in this population and design more effective interventions to increase awareness of empathic feelings and understanding for practitioners and clients.
