Background. Frailty in the elderly has a bad impact on health, especially in the elderly with acute illness. Elderly with frailty has an increase susceptibility to falls, disability and death. Frailty is a common problem in elderly patients, and hypoalbuminemia suggested to increase the risk of death. This study aimed to determine the relationship between albumin and frailty.Method: A Cross-Sectional Study was conducted from February 2018 to January 2019 at Sanglah Hospital with total 60 patients. Patients were divided into two groups, patients with hypoalbuminemia (albumin < 3.5 g/dL) and patients with normal serum albumin levels (albumin ? 3.5 g/dL). The frailty status assessment was measured with Fried's Frailty Phenotype questionnaire. Chi-square test was used to find the relationship between serum albumin and frailty.Result: We evaluated 60 patients, 36 patients (60%) were male and 24 patients (40%) were female. The age of the study subjects ranged from 62 to 92 years. In this study 26 patients (43.3%) with hypoalbuminemia and 34 patients (56.7%) with normal serum albumin. There were 20 patients (76.9%) with frailty in the hypoalbuminemia group, compared to 11 patients (32.4%) in the group of patients with normal serum albumin. Hypoalbuminemia has a risk of 6.97 times greater frailty compared to normal albumin in elderly patients (p = 0.001).Conclusion: This study exhibited a significant relationship between serum albumin and frailty in elderly admitted to inpatient unit and outpatient clinic. The lower the serum albumin level, the higher the probability of the elderly to experience frailty.

Teaching and learning probability using games: A systematic review of research from 2010-2020
Authors: Sharna Sashi , Sharma Shweta , Doyle Phil , Marcelo Louis , Kumar Daniel 
Published: February 2022

Probability is relatively a new discipline in school curricula in many countries. There is rich literature on students’ personal beliefs and misconceptions in probability. However, less attention has been paid to the development of students’ probabilistic thinking in the classroom. Recently suggestions have been made to use games and simulations to overcome misconceptions in probability. This paper presents a systematic literature review that focuses on identification of games for the teaching and learning of probability at the school level. It maps out mathematics and statistics education research literature from 2010-2020 and targets student participants from Year 1-13 and pre-service teachers along with a set of inclusion and exclusion criteria. The analysis process identified six different categories of games that can be used in teaching and learning of probability. While a large number of games discussed in literature involved the use of tokens, coins or dice, only one study used a cultural game to enhance student learning in probability. The paper draws some conclusions and offers suggestions for further research in this area.
„Rodzinna Atmosfera” i „Uprzejma Obsługa”. W stronę substantywnej teorii obsługi ruchu turystycznego – komunikat z badań
Authors: Gorzko Marek 
Published: February 2022

W artykule, który ma charakter komunikatu z badań, poświęconych interakcjom pomiędzy turystami a personelem podmiotów zajmujących się obsługą ruchu turystycznego, zaprezentowano jeden z ważnych aspektów pola przedmiotowego: konsekwencje obecności “Obcego” w przestrzeni udostępnionej.
Za pomocą procedur strategii teorii ugruntowanej wyróżniono dwie wiązki strategii modelowania pola interakcji z “obcymi”. “Uprzejma Obsługa” polega na takim zaaranżowaniu tego pola, które pozwala utrzymać równowagę pomiędzy kontrolą i otwartością na “obcego” poprzez utrzymanie go w swego rodzaju dystansie. “Rodzinna Atmosfera” z kolei polega na kontroli “obcych” poprzez włączenie tych, którzy przejdą specyficzny proces selekcji, w sieć więzi.

A Novel Fluoroscopic View for Improved Assessment of the Safety of the Posterosuperior Screw in Femoral Neck Fracture Fixation
Authors: Terhune E. Bailey , Polce Evan M. , Williams Joel C. 
Published: February 2022

Background:
The purpose of the present study was to determine specific fluoroscopic views of the femoral neck to accurately identify partially extraosseous (“in-out-in”; IOI) placement of the posterosuperior screw for fixation of femoral neck fractures.

Methods:
A 3.2-mm guide pin was placed in the posterosuperior aspect of 2 synthetic femur models: 1 entirely intraosseous and 1 IOI. Sequential fluoroscopic images were made at 5° intervals in order to identify which fluoroscopic projections identified IOI guide pin placement. These images were utilized to inform screw placement and assessment in the second phase of the study, which involved the use of cadaveric specimens. In Phase II, the posterosuperior screw of the inverted triangle was placed in 10 cadaveric specimens with use of a standard posteroanterior fluoroscopic view and 1 of 2 lateral views, either (1) neck in line with the shaft, i.e., 0° lateral; or (2) a −15° rollunder view. The final fluoroscopic views (i.e., the posteroanterior and multiple lateral and oblique views) were randomized and blinded for review by 10 orthopaedic residents and 5 attending orthopaedic traumatologists. Specimens were stripped of soft tissue and inspected for screw perforation.

Results:
Overall accuracy of respondents was 68.8%, with no difference between the attending traumatologists (71.8%) and resident surgeons (67.4%; p = 0.173). Interobserver reliability was moderate (κ = 0.496). Dissection identified that 4 (40%) of 10 screws were extraosseous. All of the extraosseous screws were placed with use of the 0° lateral view. The −15° rollunder lateral view was the most sensitive (81.7%) and specific (92.2%) view for identifying IOI screw placement.

Conclusions:
Surgeons often utilize the standard posteroanterior and 0° lateral fluoroscopic views to safely place screws; however, many of these screws are IOI. The addition of a −15° rollunder lateral view significantly improved identification of IOI screws in the posterosuperior femoral neck. Unidentified IOI screw placement may result in damage to the blood supply of the femoral head.

Published: February 2022

Abstract
In this paper, a compressed image transmission scheme is proposed in a precoded orthogonal frequency division multiplexing (OFDM)-based visible light communication (VLC) system. First, an image is divided into sub-block images; then, each block image is sampled by block-based compressive sensing (BCS) based on the Hadamard sparse basis matrix with a partial DCT measurement matrix. The resulting data are transformed into bit stream, which is transmitted in a DFT precoded OFDM-based VLC. We propose an integrated end-to-end OFDM-based VLC system platform, including BCS, quantization, VLC link, and OFDM transmission. The simulation results prove the effectiveness of the proposed simulation platform. The bit error rate (BER) and peak signal-to-noise ratio (PSNR) performances of the simulation platform are evaluated as well. The simulation results show that different images result in different BER and PSNR performances in the proposed precoded OFDM-VLC system. The larger the information entropy of images, the better the PSNR and BER performances. In addition, the PAPR of the DFT precoded OFDM can be significantly reduced compared to that of the conventional OFDM for compressed image data.
Quantifying The Leadership and Social Media Predictors of Violence and Racism during the January 6th Attack on the Capitol

Published: February 2022

Abstract
Protests involving brute force are growing in number and are now viewed as one of the mostly likely sources of collective violence in the U.S.1 Yet our scientific understanding of how violent protests is related to leadership rhetoric and social media communications during protests remains nascent2–6. Here we analyze new data from the U.S. Capitol insurrection to quantify the links between leadership actions, social media communications, and levels of violence and racism during on the day of 1/6/21. Using Granger causality methods to analyze former President Trump’s tweets, #StopTheSteal tweets, rally speeches, and live-action videos, we find that Trump’s tweets and speech predicted rioters’ levels of violence and weapons use. Trump’s tweets also predicted increased levels of the #StopTheSteal tweets, which in turn predict escalations in attacks and beatings, dangerous weapons, and symbols of racism. NLP analyses indicate that a tweet’s sentiment predicts different forms of violence and racism and at different levels. The findings demonstrate how the interplay of authority figure behavior and social media is predictive of shifts from peaceful protest to physical violence.

Published: February 2022

Abstract
The end Permian extinction (EPE) has been considered to be contemporaneous on land and in the oceans. However, re-examined floristic records and new radiometric ages from Gondwana indicate a nuanced terrestrial ecosystem response to EPE global change. Paleosol geochemistry and climate simulations indicate paleoclimate change likely caused the demise of the widespread glossopterid ecosystems on Gondwana. Here, we evaluate the climate response of plants to the EPE via dendrochronology to produce annual-resolution records of tree ring growth for a succession of Late Permian and early Middle Triassic fossil forests from Antarctica. Paleosol geochemistry provides a broader context paleoclimate history. The plant responses to this paleoclimate change were accompanied by enhanced stress during the latest Permian. These results suggest that paleoclimate change during the Late Permian exerted significant stress on high-latitude forests, consistent with the hypothesis that climate change was likely the primary driver of the extinction of the glossopterid ecosystems.

Abstract
IntroductionPositive urine sample is a frequent finding in post-chemotherapy febrile neutropenia (FN) and can lead to prolonged antibiotic therapy. The aim of this study was to assess the outcome of bacteriuria episodes in FN patients receiving targeted antibiotic therapy.Materials and methodsA multicentric retrospective study was conducted over a four-year period (2014-2019). All consecutive first bacteriuria episodes (≤2 bacteria with at least ≥103 CFU/mL) during FN in hospitalized adult patients for hematological malignancies were included. Relapse and recurrence were defined by fever or urinary tract symptoms (UTS) with the same bacterial subspecies in urine occurring ≤ 7 days and ≤30 days, respectively, after antibiotic discontinuation. Mortality rate was determined at 30 days. Targeted antibiotic therapy ≤10 days for women and ≤14 for men was considered as short course.ResultsAmong 97 patients, 105 episodes were analyzed; 67.6% occurred in women, 41.9% in AML patients, 17.1% were bacteremic, 14.2% presented with UTS, and 61.9% were treated with short-course antibiotic treatment. One death was reported. In men, no relapse/recurrence was noted, even in the short-course antibiotic group. In women, 2.8% of episodes treated with short-course antibiotic led to relapse or recurrence.ConclusionsRelapse, recurrence, and mortality were uncommon events in FN patients experiencing bacteriuria episode, whatever the antibiotic duration. To distinguish asymptomatic bacteriuria from infection remained challenging in women. In men, the withdrawal of systematic urinalysis at onset of FN could lead to insufficient bacteriuria diagnosis and treatment.
Neuroprotective Effects of Theobromine in Permanent Bilateral Common Carotid Artery Occlusion Rat Model of Cerebral Hypoperfusion
Authors: Bhat Javeed Ahmad , Kumar Manish 
Published: February 2022

Abstract
Cerebral hypoperfusion (CH) is a common underlying mechanism of dementia disorders linked to aberrations in the neurovascular unit. Hemodynamic disturbances adversely affect cellular energy homeostasis that triggers a sequence of events leading to irrevocable damage to the brain and neurobehavioral discrepancies. Theobromine is a common ingredient of many natural foods consumed by a large population worldwide. Theobromine has shown health benefits in several studies, attributed to regulation of calcium homeostasis, phosphodiesterase, neurotransmission, and neurotrophins. The current study evaluated the neuroprotective potential of theobromine against CH in the permanent bilateral common carotid artery occlusion (BCCAO) prototype. Wistar rats were distributed in Sham-operated (S), S+T100, CH, CH+T50, and CH+T100 groups. Animals received permanent BCCAO or Sham treatment on day 1. Theobromine (50, 100 mg/kg) was given orally in animals subjected to BCCAO for 14 days daily. CH caused neurological deficits (12-point scale), motor dysfunction, and memory impairment in rats. Treatment with theobromine significantly attenuated neurological deficits and improved sensorimotor functions and memory in rats with CH. In biochemistry investigation of the entire brain, findings disclosed reduction in brain oxidative stress, inflammatory intermediaries (tumor necrosis factor-α, interleukin-1β and -6, nuclear factor-κB), markers of cell demise (lactate dehydrogenase, caspase-3), acetylcholinesterase activity, and improvement in γ-aminobutyric acid quantity in rats that were given theobromine for 14 days daily after CH. Histopathological analysis substantiated attenuation of neurodegenerative changes by theobromine. The findings of this study indicated that theobromine could improve neurological scores, sensorimotor abilities, and memory in CH prototype.
