Exercise as a treatment for clinical depression in adults and progressing the physiotherapists role: A systematic review and meta-analysis
Authors: Davis Mary E. , McGrane Niall
Published: July 2021

BACKGROUND: There has been extensive literature examining the efficacy of exercise interventions in the treatment of depression over the past few decades. However, there is ongoing debate regarding the optimal dosage, and the implications of utilising physiotherapists for the management of clinically depressed adults using exercise has not been examined. OBJECTIVES: This review aimed to examine the effectiveness of exercise as a treatment for depression (without comorbidities) and to determine the most effective dosage/mode to treat this population. This review strived to appraise the literature for a potential role for physiotherapists in depression management. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, a search for randomized controlled trials was conducted on the nine databases. All studies were appraised for quality using the Physiotherapy Evidence Database (PEDro) scale and Cochrane Risk of Bias Tool (RoB). Data was manually extracted, and pre- and post-intervention depression scores and program variables were analysed. RESULTS: Of the 5036 papers retrieved, 7 papers met this review’s inclusion criteria. The results of the meta-analysis reveal that exercise as a sole treatment and as an add-on is significantly effective in reducing depressive symptoms. The findings support the use of moderate intensity aerobic exercise for three sessions per week. CONCLUSIONS: Exercise was shown to significantly improve depressive symptoms in depressed adults. This review adds to the growing body of evidence regarding the important role of physiotherapists in the treatment of psychiatric disorders in the design and implementation of exercise interventions.

Authors: Stephens Gareth , Maarabouni Ahmed , Mansell Gemma , Littlewood Chris
Published: July 2021

INTRODUCTION: Approximately 14,000 – 21,500 individuals per year are dissatisfied with the outcome of their Total Knee Replacement (TKR) in the UK National Health Service (NHS). National Institute of Clinical Excellence (NICE) guidelines recommend that future research should evaluate whether a ‘full programme of pre-habilitation’ can improve outcomes for patients awaiting TKR. The aim of this review was to describe current pre-habilitation practice for patients awaiting TKR in the UK NHS, to inform future research. METHODS: Two reviewers independently undertook electronic searches for publicly available information sheets (PIS) from websites of UK NHS Trusts that included detail about pre-habilitation for patients awaiting TKR. One reviewer extracted data, and a second reviewer verified this. RESULTS: Fifty PIS, nine information videos and one web page from 59 NHS Trusts were identified. NHS Trusts most commonly provide patients with advice on pre-operative rehabilitation via a single appointment, combined with a PIS (36/59; 61.0%). NHS Trusts use appointments, PIS and video to provide patients awaiting TKR with information regarding pain control (46/58; 79.3%), exercise therapy (46/58; 79.3%), what to expect on the day of surgery and in-patient stay (58/58; 100%), lifestyle interventions (27/58; 46.6%), and adverse events (44/58; 75.9%). CONCLUSION: NHS Trusts commonly provided patients awaiting TKR with ‘advice on pre-operative rehabilitation’, however no NHS Trust provided a comprehensive programme of pre-habilitation. The results of this study will inform the development of a comprehensive, multi-modal pre-habilitation programme, to be tested in a future high-quality randomised controlled trial.
A feasibility study of time of flight cone beam computed tomography imaging
Authors: Romero Ignacio O. , Li Changqing
Published: July 2021

BACKGROUND: The time of flight (TOF) cone beam computed tomography (CBCT) was recently shown to reduce the X-ray scattering effects by 95% and improve the image CNR by 110% for large volume objects. The advancements in X-ray sources like in compact Free Electron Lasers (FEL) and advancements in detector technology show potential for the TOF method to be feasible in CBCT when imaging large objects. OBJECTIVE: To investigate the feasibility and efficacy of TOF CBCT in imaging smaller objects with different targets such as bones and tumors embedded inside the background. METHODS: The TOF method used in this work was verified using a 24 cm phantom. Then, the GATE software was used to simulate the CBCT imaging of an 8 cm diameter cylindrical water phantom with two bone targets using a modeled 20 keV quasi-energetic FEL source and various TOF resolutions ranging from 1 to 1000 ps. An inhomogeneous breast phantom of similar size with tumor targets was also imaged using the same system setup. RESULTS: The same results were obtained in the 24 cm phantom, which validated the applied CBCT simulation approach. For the case of 8 cm cylindrical phantom and bone target, a TOF resolution of 10 ps improved the image contrast-to-noise ratio (CNR) by 57% and reduced the scatter-to-primary ratio (SPR) by 8.63. For the case of breast phantom and tumor target, image CNR was enhanced by 12% and SPR was reduced by 1.35 at 5 ps temporal resolution. CONCLUSIONS: This study indicates that a TOF resolution below 10 ps is required to observe notable enhancements in the image quality and scatter reduction for small objects around 8 cm in diameter. The strong scattering targets such as bone can result in substantial improvements by using TOF CBCT.

Огляд літератури присвячений питанням особливостей професійної діяльності військовослужбовців новоствореного роду військ – Сил спеціальних операцій Збройних Сил України, зокрема, при відборі та підготовці фахівців на кваліфікаційному курсі спеціальних операцій Збройних Сил України. Узагальнено дані літератури стосовно реакцій організму до фізичних та психоемоційних навантажень. При цьому звертається увага, що результатом первинної метаболічної відповіді організму на екстремальні чинники (фізичні навантаження та стрес) є активація вільно радикального окиснення ліпідів мембран. Біохімічним маркером активації цього процесу можуть слугувати поліненасичені жирні кислоти, а їх якісні і кількісні зміни в біологічних рідинах характеризують функціональний стан організму при фізичних і психоемоційних навантаженнях. 

Систематизація літературних джерел та підходів до вирішення проблеми застосування неінвазивних методів дослідження біологічних рідин засвідчила, що на основі даних біохімічного дослідження цих рідин можна охарактеризувати рівень активації перекисного окиснення ліпідів, тобто метаболічних пристосувальних реакцій в організмі.

The objective of the present work was to evaluate the germination of lemon-scented gum (Corymbia citriodora) on different substrates. The following were tested: 1) commercial substrate, 2) sand, 3) sand + coconut fiber (2: 1), 4) coconut fiber, 5) substrate + coconut fiber (2: 1), 6) sand + substrate (2: 1) and the control treatment (germitest paper). Based on the experiment, it was observed that germination varied between 57 and 74%, although there was no significant difference between treatments. The treatments that led to a higher germination speed were the control (germitest paper), followed by the commercial substrate, coconut fiber, sand + substrate and substrate + fiber, with no significant difference, indicating that they are the best for the germination of C. citriodora seeds. The substrate based on coconut fiber is promising, as it can be considered an alternative and low-cost substrate.

Authors: Johnson John , Abraham Tina , Sandhu Monica , Peppers Brian P. , Knorzer Cathy , Lyman Brooke , Lezaic Sydney , Rowane Marija , Romanello Gennaro , Hostoffer Robert
Published: July 2021

Background:

Anaphylaxis is a life-threatening allergic reaction that is often inadequately treated in the hospital setting, leading to adverse outcomes. We hypothesize that a brief educational intervention will enhance knowledge of community-based medical professionals evaluated by pre- and post-questionnaires, leading to improved recognition and management of anaphylaxis.

Methods:

An initial questionnaire consisting of eight multiple-choice questions and two fill in response pertaining to anaphylaxis identification, management, and treatment was completed by 189 University Hospitals Regional Hospitals personnel, including faculty, nurses, student, residents, and Emergency Medical Services (EMS). The participants were then offered an educational intervention, including a 10-slide, 20-minute PowerPoint presentation on anaphylaxis, and review of the pre-educational intervention questionnaire responses, followed by a post-educational intervention questionnaire similar to the initial questionnaire. Seventy-seven participants completed the same questionnaire at a six-month follow-up to assess retention.

Results:

Participant scores improved from 62% to 94%, from the initial questionnaire to the immediate post- educational intervention questionnaire. The six-month post-educational intervention questionnaire revealed a return to near baseline (65%) medical knowledge regarding anaphylaxis

Conclusion:

Healthcare personnel demonstrate a knowledge deficit of identification and management of anaphylaxis. In the short-term, a brief, educational intervention did improve knowledge of anaphylaxis (p<0.00001). However, in the long-term, this educational intervention did not improve knowledge retention about anaphylaxis (p=0.52218). We received approval for and implemented an anaphylaxis order set in the electronic medical record (EMR) at University Hospitals, in effort to improve patient care.
Understanding extensibility of paper: Role of fiber elongation and fiber bonding
Authors: KOUKO JARMO , TURPEINEN TUOMAS , KULACHENKO ARTEM , HIRN ULRICH , RETULAINEN ELIAS
Published: July 2021

The tensile tests of individual bleached softwood kraft pulp fibers and sheets, as well as the micro-mechanical simulation of the fiber network, suggest that only a part of the elongation potential of individual fibers is utilized in the elongation of the sheet. The stress-strain curves of two actual individual pulp fibers and one mimicked classic stress-strain behavior of fiber were applied to a micromechanical simulation of random fiber networks. Both the experimental results and the micromechanical simulations indicated that fiber bonding has an important role not only in determining the strength but also the elongation of fiber networks. Additionally, the results indicate that the shape of the stress-strain curve of individual pulp fibers may have a significant influence on the shape of the stress-strain curve of a paper sheet. A large increase in elongation and strength of paper can be reached only by strength-ening fiber-fiber bonding, as demonstrated by the experimental handsheets containing starch and cellulose microfi-brils and by the micromechanical simulations. The key conclusion related to this investigation was that simulated uniform inter-fiber bond strength does not influence the shape of the stress-strain curve of the fiber network until the bonds fail, whereas the number of bonds has an influence on the activation of the fiber network and on the shape of the whole stress-strain curve.
Fate of phosphorus in the recovery cycle of the kraft pulping process
Authors: MOUSAVI MARYAM SADEGH , DEMARTINI NIKOLAI
Published: July 2021

The accumulation of nonprocess elements in the recovery cycle is a common problem for kraft pulp mills trying to reduce their water closure or to utilize biofuels in their lime kiln. Nonprocess elements such as magne-sium (Mg), manganese (Mn), silicon (Si), aluminum (Al), and phosphorus (P) enter the recovery cycle via wood, make-up chemicals, lime rock, biofuels, and process water. The main purge point for these elements is green liquor dregs and lime mud. If not purged, these elements can cause operational problems for the mill.
Phosphorus reacts with calcium oxide (CaO) in the lime during slaking; as a result, part of the lime is unavailable
for slaking reactions. The first part of this project, through laboratory work, identified rhenanite (NaCa(PO4)) as the form of P in the lime cycle and showed the negative effect of P on the availability of the lime. The second part of this
project involved field studies and performing a mass balance for P at a Canadian kraft pulp mill.
Gas dispersion in the oxygen delignification process

Published: July 2021

There has been very little knowledge about the state of gas dispersion in the oxygen delignification process, even though this has a major impact on the performance of the reactor. This paper presents a new continu-ous inline method for measuring oxygen bubble size distribution in the reactor, as well as results from studies con-ducted in softwood and hardwood lines. This new measurement worked well, and new information about oxygen bubble size, as well as how different reactor conditions affected the distribution, was obtained. For example:
• In the softwood line, the mean volume-weighted bubble size was about 0.1 mm, whereas in the hardwood line, this size was almost 10 times higher. For both lines, there was considerable variation in the measured bubble size over the long term.
• For both lines, an increase in mixer rotation speed caused a discernible decrease in the bubble size, and an increase in oxygen charge caused a discernible increase in the bubble size.
• In the softwood line, no coalescence of the bubbles in the reactor was observed, but in the hardwood line, some coalescence of the larger bubbles occurred.
• In the test conducted in the hardwood line, the use of brownstock washer defoamer caused a discernible increase in oxygen bubble size.
• In the hardwood line, reactor pressure had a noticeable effect on the amount of delignification, which indicated that improving mass transfer of oxygen (e.g., by decreasing the oxygen bubble size, in this case) should also have an increasing effect on the delignification.
PREVALENCE AND PATTERN OF SEVERE MALARIA AMONG CHILDREN IN TWO GENERAL HOSPITALS, JIGAWA STATE- NIGERIA
Authors: Sa'idu H. I. , Shiaka G. P. , Balogun J. B.
Published: July 2021

The prevalence and pattern of presentation of severe malaria differ from one area to another, in one age group and gender. A descriptive cross sectional study of children between the ages of one month and fourteen years with symptoms of severe malaria was conducted between July and December 2018 in Dutse and Birnin Kudu Local Government Area of Jigawa State. Venous blood samples were used for parasitological, hematological and biochemical examination following standard procedures. Thick and thin blood films were prepared, stained and examined at x100 magnification. A total of 172 children were considered in which, 73/167(43.7) children had severe malaria. Children less than 5 years of age had the highest percentage of severe malaria (47.1%; 95% CI = 39.5 to 54.7). Hyperpyrexia, prostration, hyper parasitemia and multiple convulsions were the commonest presentations. While metabolic acidosis, jaundice, hypoglycemia and respiratory distress were the least presenting features, no child presented spontaneous bleeding or shock. Furthermore, 21/73 children with severe malaria had only one feature of severity, 32/73 (43.8) had two features of severity, while 14/73 (19.2) of the children had up to three features. Only 4/73 (5.5) children had four of the features of severity. Chi-square analysis showed significant difference (P <0.05) in prostration and multiple convulsions among children less than and above 5 years. The prevalence of severe malaria in less than five years old is high; hence care givers should present symptoms early to the hospital in order to prevent progression to severe life threatening malaria.

Integrating Cultural Expression with Universal Emotions: How Cultural Differences in Expression Do Not Refute the Universal Hypothesis
Authors: Trkulja Kyla
Published: July 2021

The universal hypothesis of emotions argues that due to the functionality that emotions and their behavioural components provide, they show similar patterns across all cultures. Though there is substantive evidence supporting this theory, there are several cases were emotional expression does differ between cultures. This paper argues that such differences in expression are not necessarily evidence against the universal hypothesis as they are not due to innate biological differences in the emotional experience. Instead, differences in expression are the result of culture-specific learning and act to modify the expression of emotion to meet social norms. Since differences in expression are not innate, individuals are capable of experiencing emotions in an evolutionary adaptive way, regardless of culture. This has implications for better understanding individuals across cultures and why some individuals may act differently than others, despite having a similar emotional experience.
Synthesis and characterization of a solid solution series of the type Bi2MxMn4-xO10 (M = Cr3+, Co3+ and 0.0 ≤ x ≤ 2.0.)
Authors: Sarker Aparna , Rahman AKM Lutfor , Debnath Tapas , Hussain Altaf
Published: July 2021

Bi2Mn4O10 was synthesized from corresponding metal salts in glycerin by using an organic precursor-based glycerin nitrate method. The precursor was heated at various temperatures (300 – 800 °C) for about 18 hours to determine the lowest synthesis temperature for the formation of Bi2Mn4O10. The XRD patterns of the calcined samples revealed that the desired mullite type phase started to form at 600 °C, which became more crystalline with further increase of calcination temperature. Attempts were also taken to prepare chromium and cobalt incorporated solid solution series with nominal composition Bi2MxMn4-xO10 (M = Cr3+ and Co3+) by the same procedure. The XRD data of these series exhibited mullite type single phase up to x = 0.7 and 0.1 compositions for chromium and cobalt, respectively. For further insertion of M, an extra phase appeared along with the mullite type phase.

The effect of flight state parameters on the performance of photovoltaic modules in solar aircraft
Authors: Tanvir Saydul Morshed , Wenbo Xiao , Xin Jin
Published: July 2021

Based on the power generation model of photovoltaic modules, the effects of flight speed, altitude, time and area in solar aircraft on the performance of photovoltaic modules have been studied. As the flight speed increases, the power generated by the module increases but tends to saturate. When the conversion efficiency of photovoltaic modules is improved, the required power of the solar aircraft and the power generated by the photovoltaic modules are balanced at a faster flight speed. The power generated by the modules increases with the flight altitude but tends to saturate due to the drop of air temperature and the surface temperature of the module. The higher the altitude, the smaller is the atmospheric density, and atmospheric permeability, and the greater is the solar radiation intensity, and thus the power generated by the module increases. The power generated by the components is the strongest at noon. Battery performance is the strongest in summer and the weakest in winter, as the module’s performance is mainly determined by the intensity of solar radiation. Finally, the energy distribution of solar aircraft and long-time space flight has been discussed.

Published: July 2021

Ilmu Pengetahuan Sosial selanjutnya disingkat IPS mulai ramai diperdebatkan secara nasional dalam tahun 1972 pada saat Badan Penelitian Pendidikan (BP3K sekarang) membahasa rencana pembaharuan kurikulum sekolah di Indonesia. Konsep-konsep ilmu sosial yang menjadi bahan pengajaran IPS dipilih yang dapat menunjang tercapainya tujuan pengajaran. Konsep-konsep yang sudah dipilih kemudian disederhanakan dalam arti dipermudah sesuai dengan kematangan dan kemampuan peserta didik, agar mudah diserap dan dihayati. Kesimpulan yang dapat ditarik adalah bahwa walaupun masalah yang dibahas sama yaitu masalah-masalah sosial, namun IPS bukan ilmu sosial. Ia adalah bagian ilmu sosial yang dipilih dan disederhanakan serta dipolakan untuk pengajaran, karena itu tujuannya bersifat edukatif. Penelaahan ekonomi berpangkal pada dua hal yang berhadapan yaitu tidak terbatasnya jenis dan jumlah kebutuhan manusia dan adanya kelangkaan alat-alat pemuas kebutuhan (sumber-sumber produktif). Adanya kelangkaan sumber-sumber yang produktif menimbulkan masalah pokok ekonomi. Konsep ilmu ekonomi seperti tersebut disederhanakan selanjutnya disajikan kepada peserta didik agar mudah difahaminya.
