Authors: Maina Michuki , Tosas-Auguet Olga , English Mike , Schultsz Constance , McKnight Jacob 
Published: September 2020

Background: Infection prevention and control, and water sanitation and hygiene have an essential role in ensuring the quality of care and patient outcomes in hospitals. Using a modification of the World Health Organization’s water sanitation and hygiene facility improvement tool, we undertook assessments in 14 public hospitals in Kenya in 2018. The hospitals received written feedback on areas where they could make improvements. Following the first confirmed cases of COVID-19 in Kenya, we were drawn to ask whether the results of our pre-pandemic survey had led to action, and whether or not the threat of COVID-19 had focused more attention on infection prevention and control and water sanitation and hygiene. Methods: Using a semi-structured interview guide, we carried out phone interviews with key hospital leaders in 11 of the 14 hospitals. The data were transcribed and coded into thematic areas. We draw on these interviews to describe the status and awareness of infection prevention and control. Results: The infection prevention and control committee members are training health workers on infection prevention and control procedures and proper use of personal protective equipment and in addition, providing technical support to hospital managers. While some hospitals have also accessed additional funds to improve infection prevention and control, they tended to be small amounts of money. Long-standing challenges with supplies of infection prevention and control materials and low staff morale persist. Crucially, the reduced supply of personal protective equipment has led to fear and anxiety among health care personnel. Conclusions: As funds are mobilised to support care for COVID-19, we ask that funds prioritise infection prevention and control measures. This would have a profoundly positive effect on within hospital virus transmission, patient and staff safety but also lasting benefits beyond the COVID-19 pandemic.
High-speed range and velocity measurement using frequency scanning interferometry with adaptive delay lines [Invited]
Authors: Pallikarakis Christos A. , Huntley Jonathan M. , Ruiz Pablo D. 
Published: September 2020

Range (i.e., absolute distance), displacement, and velocity of a moving target have been measured with a frequency scanning interferometer that incorporates a100,000scans−1vertical-cavity surface-emitting laser with 100 nm tuning range. An adaptive delay line in the reference beam, consisting of a chain of switchable exponentially growing optical delays, reduced modulation frequencies to sub-gigahertz levels. Range, displacement, and velocity were determined from the phase of the interference signal; fine alignment and linearization of the scans were achieved from the interferogram of an independent reference interferometer. Sub-nanometer displacement resolution, sub-100-nm range resolution, and velocity resolution of12µms−1have been demonstrated over a depth measurement range of 300 mm.

Effect of Attachment Style on Selective Attention in Panic Disorder
Authors: Klipsch Ottilia , Schauenburg Henning , Nikendei Christoph , Benecke Cord , Dinger Ulrike 
Published: September 2020

Introduction: Given the heterogeneity of results in the attentional bias to threatening information in patients with panic disorder, we investigated the attentional bias toward threat and the moderating effect of attachment styles in a female-only sample of panic patients and a nonclinical control group. Methods: Female panic patients (n = 47) were compared to a female control group (n = 47) using a modified Dot Probe Task with body-related and interpersonal threat as well as attachment positive words. Results: An attentional bias toward threat words was not replicated. Furthermore, there was no moderation effect on attentional bias by attachment styles. However, high attachment avoidance was associated with faster reaction times (RT) in attachment positive compared to attachment threat trials in both groups. In the patient group, attachment anxiety was associated with faster RT in panic threat trials compared to attachment positive trials. Anxiously attached controls reacted faster to attachment positive vs. attachment threat trials. Discussion: No attentional bias was found in the present study. However, the findings suggest that attachment avoidance and attachment anxiety differently influence attention responses to trials that include different emotional stimuli in clinical and nonclinical, female participants. Attachment insecurity may modify attention when processing trials including both, threat and positive stimuli.
The Spectral Behavior of Ground Coseismic Motion in the Baikal Region: Effect of Seasonal Thawing–Freezing Cycles
Authors: Dzhurik V.I. , Bryzhak E.V. , Serebrennikov S.P. , Eskin A.Yu. 
Published: September 2020

Abstract
—Reliable solution of theoretical and applied seismological problems requires the knowledge of natural factors that influence ground motion induced by earthquakes. The effect of seasonal freezing and thawing on the behavior of coseismic ground motion in the Baikal region has been studied using data on local geology, earthquake source parameters, seismogeology, and seismic risk zoning for East Siberia. East Siberia, including the highly seismic Baikal region, is located in a temperate and cold, sharply continental climate, with the mean annual air temperature locally falling below –10 ºC. In this respect, the knowledge of seasonal variations in the ground motion spectra in different seismic-climatic zones of the region is of special importance. We study the dynamic parameters of seismic signals and their variations caused by seasonal thawing and freezing of the ground, using calculated spectra of selected earthquakes that were recorded by 0.5–20 Hz digital seismic stations at a sampling interval (Δ) of 0.01 s. Spectral analysis was applied to three-component records of more than two hundred M = 2.8 (K = 9–14) earthquakes that occurred in the region for the past twenty years at distances from 32 to 280 km from the stations. The influence of seasonal temperature variations on the frequency responses of coseismic ground motion is discussed for the case of two seismic stations in zones of continuous and sporadic permafrost. The results are complemented by generalized data from other seismic stations located in different permafrost conditions within the Baikal region. The effect of seasonal freezing and thawing turns out to be the most prominent at frequencies above 5–6 Hz and depend on the properties and thermal state of soils beneath the stations. At the same time, they are more prominent in thawing than in freezing curves for any soil, including relatively solid bedrock. The spectral behavior of earthquake-induced ground motion is associated with variations in wave amplitudes, which correlate with seasonal temperature variations. The reported results have implications for geophysical prospecting, seismic-risk zoning, and prediction of shaking intensity of large earthquakes, which require due regard for local permafrost conditions.
Geologic Structure and Hydrocarbon Generation Potential of Devonian Terrigenous Strata in the Perm’ Territory
Authors: Kozhevnikova E.E. 
Published: September 2020

Abstract
—The work is a study of the geologic structure and hydrocarbon generation potential of Devonian terrigenous strata in the Perm Territory. Prediction for new oil fields is made using quantitative criteria for determining the scale of oil generation by the petroleum source rocks of this petroleum system and the scale of the oil migration. An integrated approach is used, which makes it possible to follow all stages of petroleum generation in the Devonian terrigenous strata. The above petroleum system is the most buried of all commercial ones in the region; it has an intricate geologic structure and is less drilled than others but is considered to be promising for oil resource enhancement. Therefore, a comprehensive assessment with regard to both quantitative criteria and genetic parameters is a necessary step in the future planning of geological surveys. The results obtained during this work point to a low hydrocarbon generation potential of the Devonian terrigenous strata within the study area. This research has first established no genetic relationship between the oils and the organic matter of the Devonian terrigenous strata but has revealed a genetic relationship between these oils and the oils and organic matter of the Upper Devonian–Tournaisian petroleum system. It is shown that oil fields where oil deposits are present in Devonian terrigenous strata usually have reservoirs in the overlying Upper Devonian–Tournaisian petroleum system as well. This phenomenon is most often observed on the flanks of the Kama–Kinel’ depression system. The development of oil fields there gives a high chance of discovering new oil deposits. Taking into account the new data, it is necessary to revise the search criteria and perform geological surveys in the Devonian terrigenous strata, primarily in the areas of explored oil fields where oil is localized in the Upper Devonian–Tournaisian petroleum system.

Abstract
—We consider the ranges of current and voltage values for laterolog tools. It is shown that expansion of the dynamic range of these parameters is possible by mathematical focusing and digital filtering and by fulfillment of the conditions for the effective number of bits and by compliance with the tool requirements. The principles of mathematical focusing are considered by the example of the 5BK tool designed by AO NPF Geofizika (Joint-Stock Company) in Ufa. The digital-filtering calculation and application technique is described. The results of well tests are presented.

Authors: Hall Trevor , Botha Jannie , Patricios Jon 
Published: September 2020

Background: Negative psychosocial sequelae of severe rugby injury (SRI) in professional rugby players are well documented. Unaddressed, these issues can leave players vulnerable to persistent common mental disorders (CMD) and negatively affect injury recovery processes.
Objective: To introduce a psychotherapeutic group intervention aimed at addressing negative psychosocial sequelae linked to SRI in professional rugby player cohorts. Methods: Literature aimed at clarifying the potential efficacy of an integrative group therapy model, the Recovery Mastery Group (RMG), is discussed after which component parts of the intervention are presented.
Case illustration: A case illustration is presented comprising examples of how the RMG framework addressed psychosocial recovery issues in a professional South African rugby team during 2019.
Conclusion: The proposed Recovery Mastery Group (RMG) is presented as a cost- and time- effective psychotherapeutic intervention that integrates well-researched psychotherapeutic techniques. The RMG appears able to address multiple facets of psychosocial injury recovery, while possibly offering protection from the onset of CMD. This introduction to the RMG can be a forerunner of similar research across larger cohorts, in different team sports, to determine wider therapeutic intervention efficacy.

Published: September 2020

Background: Acquired Immunodeficiency Syndrome (AIDS) is one of the diseases that cause death in the world caused by the Human Immunodeficiency Virus (HIV). Since it was first discovered in 1987 until December 2017, the number of person with AIDS was 102,667, and the number of person with HIV infections was 280,623. HIV/AIDS cases in East Java occupy the second highest position in Indonesia. Surabaya is the first city in East Java with 934 HIV cases in 2017. LGBTQ is one of the groups at risk of getting HIV/AIDS with prevalence was 24.82%. Objective: The purpose of this study was to analyze the factors that influence LGBTQ related to the incidence of HIV/AIDS in Surabaya. Material and Method: This study was an analytic research using a cross sectional approach. The subject was 80 LGBTQ respondents. Data was collected using questionnaires then analyzed using Chi-square test, with α = 0.05. Result: The highest age group was 42-46 years (22.5%), the last level of education was dominated by high school (41.3%), and the most types of work were private employees (47.4%). There was no correlation between predisposing factors in the form of knowledge about HIV/AIDS and respondent's HIV status (p = 0.729), there was no correlation between enabling factors in the form of condoms and respondent's HIV status (p = 0.624), there was no correlation between the reinforcing factor in the form of family support with the HIV status of the respondent (p = 0.674) and there was no correlation between preventive behavior and the HIV status of the respondent (p = 0.540). Conclusion: The need for support between LGBTQs for the dangers of HIV/AIDS and LGBTQ should be more aware of their own health and environment with their social patterns

Published: September 2020

Abstract
As climate-driven El Niño Southern Oscillation (ENSO) events are projected to increase in frequency and severity, much attention has focused on impacts regarding ecosystem productivity and carbon balance in Amazonian rainforests, with little attention given to carbon dynamics in fluvial ecosystems. We compared the wet 2012 La Niña period to the following normal hydrologic period in the Amazon River. Elevated water flux during the La Niña was accompanied by dilution of inorganic ion concentrations. Furthermore, the La Niña period exported 2.77 TgCyr-1 more dissolved organic carbon (DOC) than the normal period, an increase greater than annual Mississippi River DOC export. Using ultra-high-resolution mass spectrometry, we detected both seasonal and inter-annual variations in dissolved organic matter (DOM) compositions, revealing that DOM exported during the dry season and the normal period was more aliphatic, whereas compounds in the wet season and following the La Niña event were more aromatic, with ramifications for its environmental role. Furthermore, compounds were highly correlated to a 6-month lag in Pacific temperature and pressure anomalies, demonstrating that ENSO events impact DOM compositions exported to the Atlantic Ocean.

Abstract
Background: Gastric cancer (GC) is one of the most common solid malignant tumors worldwide with a high-recurrence-rate. Identifying the molecular signatures and specific biomarkers of GC might provide novel clues for GC prognosis and targeted therapy.Methods: Gene expression profiles were obtained from the ArrayExpress and Gene Expression Omnibus database. Differentially expressed genes (DEGs) were picked out by R software. The hub genes were screened by cytoHubba plugin. Their prognostic values were assessed by Kaplan–Meier survival analyses and the gene expression profiling interactive analysis (GEPIA). Finally, qRT-PCR in GC tissue samples was established to validate these DEGs. Results: Total of 295 DEGs were identified between GC and their corresponding normal adjacent tissue samples in E-MTAB-1440, GSE79973, GSE19826, GSE13911, GSE27342, GSE33335 and GSE56807 datasets, including 117 up-regulated and 178 down-regulated genes. Among them, 7 vital upregulated genes (HMMR, SPP1, FN1, CCNB1, CXCL8, MAD2L1 and CCNA2) were selected. Most of them had a significantly worse prognosis except SPP1. Using qRT-PCR, we validated that their transcriptions in our GC tumor tissue were upregulated except SPP1 and FN1, which correlated with tumor relapse and predicts poorer prognosis in GC patients.Discussion: We have identified 5 upregulated DEGs (HMMR, CCNB1, CXCL8, MAD2L1, and CCNA2) in GC patients with poor prognosis using integrated bioinformatical methods, which could be potential biomarkers and therapeutic targets for GC treatment.

Abstract
Background To investigate which baseline factors are predictive for axial length growth over an average period of 1 years in a group of adolescents wearing orthokeratology (OK) contact lenses.Methods In this retrospective study, the clinical records of 189 new OK wearers (378 eyes) between 2014 and 2018 at Xiangya Hospital of Central South University were reviewed. The primary outcome measure was axial length change from baseline to the time of 1 year. Independent variables included baseline measures of age at initiation of OK wear, refractive error (spherical equivalent), corneal thickness, corneal curvature. (1) Age group, 8 ~ 10 years old is the first group, 10 ~ 13 years old is the second group, ≥13 years old is the third group; (2) Myopia degree group, ≥-3.00D is the first group, -3.00 ~ -6.00D is the second group, <-6.00D is the third group; (3) corneal thickness group, ≤550μm is the first group,> 550μm is the second group; (4) corneal curvature group, ≤42.0D is The first group, 42.0 ~ 44.0D is the second group,> 44.0D is the third group.Results ANOVA was used to analyze the difference between the baseline axial length of each group and the axial length for 1 year after continuous wearing of orthokeratology: (1)The mean axial difference between different age groups are 0.251mm, 0.033mm,and 0.112mm, and the difference of the three groups is not statistically significant (F=2.279，P=0.104). By pairwise comparison, only the difference between the first group and the third group is statistically significant (P=0.041); (2) The mean axial difference between different myopia degree groups are 0.173mm, 0.109mm and -0.008mm, and the difference of the three groups is statistically significant (F=8.340，P=0.000 ). By pairwise comparison, the difference between the first group and the second group is statistically significant (P=0.000) and the difference between the first group and the third group is statistically significant(P=0.016); (3) The mean axial difference between different corneal thickness groups and corneal curvature groups is not statistically significant.Conclusions OKs are effective in controlling axial length elongation and myopic progression in adolescents, particularly in younger children with higher myopia.
