The SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) Lambda variant rapidly diffused across Peru following its identification in December 2020, and had now spread worldwide. In this study, we investigated infodemiologic trends in symptomatology associated with the Coronavirus Disease 2019 (COVID-19) following the spread of SARS-CoV-2 Lambda variant in Peru, enabling infodemiologic surveillance of SARS-CoV-2 in regions with high circulation of this new variant. Weekly Google Trends scores were obtained for key symptom keywords between March 1st, 2020 and July 4th, 2021, whilst case count data were obtained from Peruvian Ministry of Health. Multiple time series linear regression was used to assess trends in each score series, using the week of December 27th as cutoff for emergence of the Lambda variant. The significance of such trends was tested for each time period, before and after the cutoff date. A total 2,075,484 confirmed SARS-CoV-2 infections in Peru in relation to Google Trends data were analyzed. After Lambda variant emergence, searches for diarrhea demonstrated a change from a negative to positive correlation with weekly case counts and anticipated dynamic changes in case counts by 1-5 weeks. Searches for shortness of breath and headache remained consistently positively correlated to weekly case counts before and after Lambda emergence. No changes in searches for other common cold symptoms were observed, while no specific trends were observed for taste loss or smell loss. Diarrhea, headache, and shortness of breath appear to be the most important symptoms for infodemiologic tracking the current outbreak in Peru and other regions with high circulation of SARS-CoV-2 Lambda variant.

Abstract Background When a new or re-emergent pathogen, such as SARS-CoV-2, causes a major outbreak, rapid access to pertinent research findings is crucial for planning strategies and decision making. We researched whether the speed of sharing research results in the COVID-19 epidemic was higher than the SARS and Ebola epidemics. We also researched whether there is any difference in the most frequent topics investigated before and after the COVID-19, SARS, and Ebola epidemics started. Methods We used PubMed database search tools to determine the time-period it took for the number of articles to rise after the epidemics started and the most frequent topics assigned to the articles. Results The main results were, first, the rise in the number of articles occurred 6 weeks after the COVID-19 epidemic started whereas, this rise occurred 4 months after the SARS and 7 months after the Ebola epidemics started. Second, etiology, statistics & numerical data, and epidemiology were the three most frequent topics investigated in the COVID-19 epidemic. However, etiology, microbiology, and genetics in the SARS epidemic, and statistics & numerical data, epidemiology, and prevention & control in the Ebola epidemic were more frequently studied compared with other topics. Third, some topics were studied more frequently after the epidemics started. Conclusions The speed of sharing results in the COVID-19 epidemic was much higher than the SARS and Ebola epidemics, and that there is a difference in the most frequent articles’ topics investigated in these three epidemics. Due to the value of time in controlling epidemics spread, the study highlights the necessity of defining more solutions for rapidly providing pertinent research findings in fighting against the next public health emergency.

Craniofacial Fractures

Electric scooters are an increasingly common and convenient mode of transportation worldwide and have effectively revolutionized the shared micromobility industry. As electric scooter sharing companies have increased in popularity there has been a concomitant increase in the frequency of all electric scooter-related injuries. The purpose of this study is to describe the most up-to-date trends in craniofacial fractures and lacerations related to electric scooter use among all age groups. We queried the National Electronic Injury Surveillance System (NEISS) for craniofacial fractures and lacerations related to e-scooters between 2010 and 2019. We then compared injury trends over time and between time periods before and after 2017 when electric scooter share apps revolutionized micromobility. We compared incidence of injury overall and by day of the week, patient demographics, and case severity based on clinical disposition. We identified an increase in the frequency of craniofacial lacerations and fractures in the 3 years following the introduction of electric scooter share services in 2017 (2017 and 2019), compared to the 3 years before this time (2014-2016). Young adults (18-39 years) were the age group with the greatest interval increase in craniofacial injuries. There was also an increase in number of craniofacial injuries occurring on Mondays and a decrease number occurring on Fridays in the later time period. Finally, patients who presented with electric scooter-related craniofacial injuries in this later time period showed a higher frequency of overnight observation and hospital admission for their injuries. The number of craniofacial injuries secondary to electric scooter use has increased dramatically since the introduction of share services. Craniofacial fractures and lacerations are a common reason for craniofacial or maxillofacial surgery consultation and understanding these patterns of injury will help prepare surgeons for patient care, preventative education, and public advocacy.

BackgroundProlonged sedentary behaviour is associated with a higher risk of cardiometabolic diseases. This longitudinal study examined changes in daily total, prolonged (≥30 min) and highly prolonged (≥60 min) sedentary time across the transition to retirement by gender and occupational status.MethodsWe included 689 aging workers (mean (SD) age before retirement 63.2 (1.6) years, 85% women) from the Finnish Retirement and Aging Study (FIREA). Sedentary time was measured annually using a wrist-worn triaxial ActiGraph accelerometer before and after retirement with on average 3.4 (range 2–4) measurement points.ResultsWomen increased daily total sedentary time by 22 min (95% CI 13 to 31), prolonged sedentary time by 34 min (95% CI 27 to 42) and highly prolonged sedentary time by 15 min (95% CI 11 to 20) in the transition to retirement, and remained at the higher level of sedentary time years after retirement. The highest increase in total and prolonged sedentary time was observed among women retiring from manual occupations. Men had more total and prolonged sedentary time compared with women before and after retirement. Although no changes in men’s sedentary time were observed during the retirement transition, there was a gradual increase of 33 min (95% CI 6 to 60) in prolonged sedentary time from pre-retirement years to post-retirement years.ConclusionThe transition to retirement was accompanied by an abrupt increase in prolonged sedentary time in women but a more gradual increase in men. The retirement transition may be a suitable time period for interventions aiming to decrease sedentary behaviour.

In this prospective clinical study, the Q-Switched Nd:YAG 1064 nm/532 nm laser (Light Age, Inc., Somerset, NJ, USA) was used on 131 onychomycosis subjects (94 females, 37 males; ages 18 to 68 years). Mycotic cultures were taken and fungus types were detected. The laser protocol included two sessions with a one-month interval. Treatment duration was approximately 15 minutes per session and patients were observed over a 3-month time period. Laser fluencies of 14 J/cm2were applied at 9 billionths of a second pulse duration and at 5 Hz frequency. Follow-up was performed at 3 months with mycological cultures. Before and after digital photographs were taken. Adverse effects were recorded and all participants completed “self-evaluation questionnaires” rating their level of satisfaction. All subjects were well satisfied with the treatments, there were no noticeable side effects, and no significant differences were found treating men versus women. At the 3-month follow-up 95.42% of the patients were laboratory mycologically cured of fungal infection. This clinical study demonstrates that fungal nail infections can be effectively and safely treated with Q-Switched Nd:YAG 1064 nm/532 nm laser. It can also be combined with systemic oral antifungals providing more limited treatment time.

ObjectivesTo examine the characteristics of paediatric attendances to the emergency department (ED) in Cork University Hospital (CUH) before and after the expansion of free general practitioner (GP) care to children under the age of 6 years.DesignThis is a retrospective observational study that used a large administrative dataset.SettingThe study was conducted in major Irish tertiary referral centre that serves a total population of over 1.1 million. It is a public hospital, owned and managed by the health service executive.ParticipantsChildren aged 0–15 years who attended CUH ED during the study period of 6 years (2012–2018) were included in this study (n=76 831).InterventionsFree GP care was expanded to all children aged 0–5 years in July 2015.Main outcome measuresPaediatric attendances to CUH ED were examined before (Time Period 1: July 2012–June 2015) and after (Time Period 2: July 2015–June 2018) the expansion of free GP care to children under 6. Changes in GP referral rates and inpatient hospital admissions were investigated.ResultsPaediatric presentations to CUH ED increased from 35 819 during the Time Period 1 to 41 012 during the Time Period 2 (14.5%). The proportion of the CUH ED attendances through GP referrals by children under 6 increased by over 8% in the Time Period 2 (from 10 148 to 14 028). Although the number of all children who attended CUH ED and were admitted to hospital increased in Time Period 2 (from 8704 to 9320); the proportion of children in the 0–5 years group who attended the CUH ED through GP referral and were subsequently admitted to hospital, decreased by over 3%.ConclusionThe expansion of free GP care has upstream health service utilisation implications, such as increased attendances at ED, and should be considered and costed by policy-makers.

AbstractIn this study, we characterized the dynamics and analyzed the degree of synchronization of the time series of daily closing prices and volumes in US$ of three cryptocurrencies, Bitcoin, Ethereum, and Litecoin, over the period September 1,2015–March 31, 2020. Time series were first mapped into a complex network by the horizontal visibility algorithm in order to revel the structure of their temporal characters and dynamics. Then, the synchrony of the time series was investigated to determine the possibility that the cryptocurrencies under study co-bubble simultaneously. Findings reveal similar complex structures for the three virtual currencies in terms of number and internal composition of communities. To the aim of our analysis, such result proves that price and volume dynamics of the cryptocurrencies were characterized by cyclical patterns of similar wavelength and amplitude over the time period considered. Yet, the value of the slope parameter associated with the exponential distributions fitted to the data suggests a higher stability and predictability for Bitcoin and Litecoin than for Ethereum. The study of synchrony between the time series investigated displayed a different degree of synchronization between the three cryptocurrencies before and after a collapse event. These results could be of interest for investors who might prefer to switch from one cryptocurrency to another to exploit the potential opportunities of profit generated by the dynamics of price and volumes in the market of virtual currencies.

AbstractSiamang gibbons produce long and complex duet songs. The hypothesis that duetting may act as advertisement of the presence and the status of a mated pair has repeatedly been suggested for duetting birds. If a pair bonding effect of the duet is actually attained through a partner-directed learning effort resulting in a pair-specific duet, the learning investment should be concentrated into a time period as short as possible in order to avoid competitors. Therefore, after the formation of a new pair, an increase of singing activity should be expected. In order to test this prediction, the singing activity of a pair of captive siamang before and after a partner exchange was compared. In the newly formed pair, an increase in singing activity was observed. Additional observations on a second new pair show a similar trend. In this case, both new mates remained in their familiar place so that their singing activity was unlikely to be affected by the process of establishing a new territory.

Background Since the start of the COVID-19 pandemic, less acute care surgical procedures have been performed and consequently hospitals have experienced significant revenue loss. We aim to investigate these procedures performed before and after the start of the COVID-19 pandemic, as well as their effect on the economy. Methods This is a retrospective analysis of patients who underwent cholecystectomies and appendectomies during March–May 2019 compared to the same time period in 2020 using Chi-square and t-tests. Results There were 345 patients who presented with appendicitis or cholecystitis to Elmhurst Hospital Center during the March–May 2019 and 2020 time period. There were three times as many total operations, or about 75%, in 2019 (261) compared to 2020 (84). There was a decrease in the number of admissions from 2019 to 2020 for both acute cholecystitis (149 vs 43, respectively) and acute appendicitis (112 vs 41, respectively). The largest decrease in the number of admissions in 2020 compared to 2019 was observed in April 2020 (98 vs 9, P < .01) followed by May [69 vs 20, P < .01], and March [94 vs 55, P < .01]. Corresponding to the decrease in operative patterns was a noticeable six-time reduction in revenue for the procedures in 2019 ($187,283) compared to 2020 ($30,415). Conclusion We observed almost a triple reduction in the number of cholecystitis and appendicitis procedures performed during the 2020 pandemic surge as compared to the 2019 pre-pandemic data. Elmhurst hospital also experienced four times the loss of revenue during the same time period.

The main purpose of the present research is to investigate Pak-Afghan relations in the editorials of US newspapers, The Washington Post & The New York Times and Pakistani newspapers Dawn & The News related to the following issues during the period 1997-2005; A) US as a factor in Pak-Afghan relation, B) Coverage of Islam/Muslims regarding war on terrorism, C) Pakistan’s stance on Pak-Afghan bilateral relations, and D) US’s stance on Pak-Afghan bilateral relations. The time period to be examined in this proposed study spans over eight years regarding the editorial coverage of Pak-Afghan relations in the US and Pakistani leading English Press. Triangulation method based on qualitative and quantitative method was used to conduct the present research. The results show that the editorial contents of USA and Pakistani newspapers were not different regarding Pak-Afghan relations before and after 9/11. The incident of 9/11 changed the American foreign policy towards developing and least developing nations especially Muslims states like Pakistan, Afghanistan, Iraq, and Iran etc. Pakistani press highlighted the issues regarding the Pak-Afghan relations before and after 9/11 as a favorable and conducive, related to Muslim/Islam regarding war on terrorism. The study suggested that instead of the focus on military resolution of the different problems, rather social bilateral negations should be prioritized which would be long lasting and full of mutual respects and honor.

The Impact

The study aimed to measure the effect of applying the disclosure and transparency standards criteria adopted by the Saudi Arabian Monetary Authority on improving performance indicators in the Saudi banking sector, by measuring the extent of the impact of the bank's financial indicators represented by liquidity, profitability and return on assets in Saudi banks by applying the criteria of disclosure and transparency, which is one of the Main principles in the list of governance, which was approved by the Saudi Arabian Monetary Authority. The analytical approach was followed to achieve the goal of the study, as the financial statements of Saudi banks were analyzed during a period of 8-year to test four hypotheses related to measuring the presence of statistically significant differences between the performance indicators of banks before and after applying the disclosure and transparency standards imposed on Saudi banks. The results of the research confirmed the existence of an inverse relationship between the bank’s liquidity and the percentage of Saudi banks ’profits. The more liquidity, the lower the profitability level of banks, which indicates that the high liquidity in Saudi banks has led to a low profitability in this time period, and the study recommended that The need to pay attention to the concept of disclosure and transparency among all related parties in Saudi banks, and banks should find a balance between liquidity and profitability
