Low back pain functional disability and associated factors: A cross-sectional study in Peruvian amateur athletes
Authors: Rosales-Rimache Jaime , Chavez-León Yaritza 
Published: August 2023

Background: Low Back Pain Functional Disability is one of the most critical physical limitations found in athletes, even leading to their temporary or permanent retirement. In this sense, this research aimed to evaluate the frequency of lumbar functional disability and its associated factors. Methods: We designed transversal research and evaluated athletes from the Peruvian Sports Institute (IPD) of Ica in athletics, basketball, and table tennis. We administered a file to obtain demographic and epidemiological data. We identified low back pain with the DN4 instrument (Douleur Neuropathique 4 Questions) and lumbar functional disability with the athlete's disability index. Results: We evaluated 130 amateur athletes (table tennis=30, basketball=50, and athletics=50), with an average age of 23.9±8.2 years, and constituted 63.9% of men. 30% (CI95: 22.3-38.7%) of the population presented lumbar functional disability (moderate 56.4%, severe 30.8%, and very high 12.8%). Factors associated with lumbar functional disability were age (PR: 1.05, CI95: 1.01-1.09), female sex (PR: 2.21, CI95: 1.08-4.50) and neuropathic pain (PR: 0.35, CI95: 0.16-0.80). Conclusions: The frequency of lumbar functional disability is high among athletes who practice table tennis, basketball, and athletics. It is crucial to strengthen fitness programs accompanied by a periodic medical evaluation that allows the timely identification of injuries and potential functional disability due to low back pain.

Background: It is widely acknowledged that carbon dioxide (CO2), a greenhouse gas, is largely responsible for climatic changes that can lead to warming or cooling in various places. This disturbs natural processes, creating instability and fragility of natural and social ecosystems. To combat climate change, without compromising technology advancements and maintaining production costs at acceptable levels, carbon capture and storage (CCS) technologies can be deployed to advance a non-disruptive energy transition. Capturing CO2 from industrial processes such as thermoelectric power stations, refineries, and cement factories and storing it in geological mediums is becoming a mature technology. Part of the Mesohellenic Basin, situated in Greek territory, is proposed as a potential area for CO2 storage in saline aquifers. This follows work previously done in the StrategyCCUS project, funded by the EU. The work is progressing under the Pilot Strategy, funded by the EU. Methods: The current investigation includes geomechanical and petrophysical methods to characterise sedimentary formations for their potential to hold CO2 underground. Results: Samples were found to have both low porosity and permeability while the corresponding uniaxial strength for the Tsotyli formation was 22 MPa, for Eptechori 35 MPa and Pentalofo 74 MPa. Conclusions: The samples investigated indicate the potential to act as cap-rocks due to low porosity and permeability, but fluid pressure within the rock should remain within specified limits; otherwise, the rock may easily fracture and result in CO2 leakage or/and deform to allow the flow of CO 2. Further investigation is needed to identify reservoir rocks as well more sampling to allow for statistically significant results.

Published: August 2023

Objective: Nanosilver-alginate dressing can effectively promote the healing of diabetic wounds in rats. However, due to the potential toxicity of nanosilver, its widespread application in hard-to-heal wound healing is limited. In the present study, the role and potential mechanism of nanosilver-free alginate gel (NSFAG) in the healing process of diabetic wounds were explored. Method: A diabetic rat skin wound model was established, and wounds were treated with saline (NC group), nanosilver gel (NSG group) or nanosilver-free alginate gel (NSFAG group) for seven consecutive days. Results: NSFAG significantly promoted wound healing and increased the content of protein and hydroxyproline in granulation tissues, and was superior to NSG (p<0.05). Immunohistochemical analyses revealed that the skin wound tissue structure of the NSFAG group was intact, and the number of skin appendages in the dermis layer was significantly higher compared with the NC group and the NSG group (p<0.05). Western blot analysis found that the protein expression of the epidermal stem cell marker molecules CK19 and CK14 as well the proliferation marker of keratinocytes Ki67 in the NSFAG group was significantly higher compared with the NC group or NSG group (p<0.05). Additionally, the proliferation marker of keratinocytes Ki67 in the NSFAG group was significantly higher compared with the NC or NSG group (p<0.05). Immunofluorescence staining analyses indicated that the CK19- and CK14-positive cells were mainly distributed around the epidermis and the newly formed appendages in the NSFAG group, and this result was not observed in the NC or NSG groups. Conclusion: The present findings demonstrate that NSFAG can effectively accelerate wound healing in diabetic rats by promoting epidermal stem cell proliferation and differentiation into skin cells, as well as formation of granulation tissue, suggesting that it can be a potential dressing for diabetic wounds.
The cost of sustainable production for basmati rice grown by the Fairtrade certified producers
Authors: Chakraborty Manab 
Published: August 2023

The objective of the study is to understand the cost components of Basmati rice production, and whether the minimum price offered by Fairtrade International (FI) or the Government of India (GOI) adequately compensates the farmers.
The study adopted a survey method for the assessment of realities on the ground. Data was collected from 327 FI certified Basmati farmers in four major Indian states – Jammu, Haryana, Uttarakhand and Uttar Pradesh.
The main finding is that the Fairtrade Minimum Price (FMP), along with its premium, is 41 per cent to 78 per cent lower than the farmers’ costs for seed, labour, storage and transportation. The Minimum Support Price (MSP) provided by the GOI is 6 per cent higher than the FMP for the conventional Pusa variety, but 25 per cent lower than the FMP for organic Basmati. Neither the FMP or the MSP covers producers’ reported costs.
No study exists in India examining the cost of production of Basmati farmers under Fair Trade contracts. The study is an important contribution to the ongoing debate on the benefits of Fair Trade farming from the perspective of farmers.
Temperature and strain simultaneous sensing measurement based on an all-fiber Mach-Zehnder interferometer and fiber Bragg grating
Authors: Zhu Junjie , He Wei , Li Shaode , Li Zhihan , Zhu Lianqing 
Published: August 2023

We designed and fabricated what we believe to be a novel dual-parameter fiber optic sensor for simultaneous measurement of temperature and strain, which was composed of a femtosecond laser inscribed fiber Bragg grating (FBG), three segments of a single-mode fiber (SMF), and two segments of a multimode fiber (MMF), forming a SMF-MMF-FBG-MMF-SMF structure. The FBG and Mach–Zehnder interferometer (MZI) were present in this structure so that the changes of the temperature and strain parameters can be sensed by the shifts of the reflection center wavelength of the FBG and the interference valley wavelength of the MZI. We simulated the light field distribution of the sensor structure, compared the shapes of the interference spectra formed by the MZI structure with different sensing arm lengths of 25, 35, and 45 mm, and analyzed the spectra in the spatial frequency domain. The simulation results showed that the interference spectrum of the MZI structure with a 25 mm length sensing arm was clearer and more suitable for the experiment. The experimental results showed that the temperature sensitivity of the FBG and MZI was 14.81 and 43.54 pm/°C in the range of 80°C to 240°C, and the strain sensitivity was 1.49 and −2.58 pm/µε in the range of 0 to 1200 µε, with a high linearity and excellent repeatability. The sensor is economical, sensitive, and convenient to fabricate, and exhibits promising applications in the fields of biochemical medical detection and industrial production monitoring.
The effect of heatwaves on the number of visits to national parks and reserves
Authors: Barnett-Itzhaki Zohar , Sar-Shalom Aviv , Cohn Liav , Chen Lior , Steinitz Ofer 
Published: August 2023

Background
Climate change is leading to an increase in the frequency and intensity of heatwaves in many regions of the world. Climate change is also related to air pollution. Both heatwaves and air pollution have adverse health effects, and can also affect social behaviors, including tourism and touristic activities. The aim of this study was to examine the association between heatwaves, air pollution and visits to national parks and reserves in Israel.

Methods
Data on 68,518 visits in 51 national parks and reserves in Israel in the years 2016–2019 was crossed with temperature and air pollution data (represented by particulate matter PM10) and analyzed using statistical tests.

Results
Number of visits, as a function of temperature followed a unimodal distribution, in which more visits were reported on mild temperature days (in comparison to hot or cold days). In addition, the number of visits in sites with beaches was linearly correlated with temperature. Negative associations were found between number of visits and heatwaves, and between number of visits and exceedances in PM10 levels.

Conclusions
Heatwaves were shown to have a negative effect on the number of visits in national parks and reserves in Israel. The negative association between exceedances in air pollution and number of visits may be mediated by the positive correlation between air pollution exceedance events and heatwaves.

Published: August 2023

Introduction
Maternal HIV infection is associated with increased risk of having a preterm delivery, low birth weight baby, small for gestational age baby and stillbirth. Maternal use of combination antiretroviral treatment is also associated with preterm delivery and low birth weight, although the effects vary by the type of drugs and timing of initiation.

Objective
To examine time trends in adverse perinatal outcomes among HIV-positive compared with HIV-negative women.

Design
Registry-based cohort study.

Setting
Northern Tanzania, 2000–2018.

Study sample
Mother-baby pairs of singleton deliveries (n = 41 156).

Methods
Perinatal outcomes of HIV-positive women were compared with HIV-negative women during time periods representing shifts in prevention of mother-to-child transmission guidelines. Monotherapy was used as first-line therapy before 2007 while combination antiretroviral treatment was routinely used from 2007. Log binomial and quantile regression were used to analyze the data.

Main outcome measures
Preterm delivery, low birth weight, perinatal death, stillbirth, low Apgar score, transfer to neonatal care unit and small for gestational age.

Results
Overall, maternal HIV infection was associated with a higher risk of low birth weight and small for gestational age. Moreover, this pattern became more pronounced over time for low birth weight, the last time period being an exception. For other outcomes we found none or only a small overall association with maternal HIV infection, although a trend towards higher risk over time in HIV-positive compared with HIV-negative women was observed for preterm delivery and perinatal death. Quantile regression showed an increase in birth weight in babies born to HIV-negative women over time and a corresponding decline in birth weight in babies born to HIV-positive women.

Conclusion
Unfavourable trends in some of the selected perinatal outcomes were seen for HIV-positive compared with HIV-negative women. Potential side-effects of combination antiretroviral treatment in pregnancy should be further explored.
Association between gastroesophageal reflux disease and dental caries among adults in the Azar cohort population: A cross-sectional study
Authors: Mahboobi Zeinab , Jalili asl Ataollah , Sharififard Nasrin , Faramarzi Elnaz , Ghavamlaleh Younes 
Published: August 2023

Background
Considering the high prevalence of dental caries in adults, it is necessary to study its risk factors to prevent the disease. Gastroesophageal reflux disease (GERD) is a common chronic disease with an increasing incidence that may affect the quality and quantity of saliva.

Objectives
This study aimed to determine the association of gastroesophageal reflux disease (GERD) with dental caries according to the DMFT index in the Azar cohort population.

Materials and methods
This cross-sectional study was performed on data obtained from the enrollment phase of the Azar Cohort Study (ACS), conducted on 15,000 adults aged 35 to 70. Data of 905 subjects with gastroesophageal reflux disease in the ACS—without full denture—together with a control group of 1894 subjects, who were matched in terms of gender and age, were included in this study. Dental caries data and data on GERD, demographic and socioeconomic characteristics, individual and nutritional habits, BMI, and toothbrushing frequency were elicited from the databank of the ACS center. A Generalized Linear Models assuming negative binomial distribution with a log-link function was used for analytical statistics to examine the effect of possible confounding variables.

Results
The DMFT index in the group with GERD was 15.09±6.18, and for the control group was 15.00±6.07. No statistical association was seen between GERD and dental caries. Among the variables included in the regression analysis, being younger and toothbrushing one or more times per day were associated with a lower DMFT index score.

Conclusion
According to the results, having GERD did not increase the risk of dental caries. However, due to the cross-sectional design of the study, the results should be interpreted cautiously. The results showed that oral hygiene is one of the most influential factors in reducing dental caries prevalence.
Predicting mid-pelvic interspinous distance in women using height and pubic arch angle
Authors: Na Eun Duc , Baek Min Jung , Moon Ji Hyun , Park Cho Won , Yoon Jin , Lee Hanna , Park So Hyeon , Jang Ji Hyon 
Published: August 2023

Objective
To predict the interspinous distance (ISD) using the relationship between female height and pelvimetric measures on magnetic resonance (MR) images.

Methods
We obtained measurements of the pubic arch angle (PAA), inlet-anteroposterior (AP) distance, mid-pelvis AP distance, outlet-AP distance, ISD, and ischial tuberosity distance using 710 pelvic MR images from nonpregnant reproductive-aged (21–50 years) women from January 2014 to June 2020. Patient height was also assessed from medical records. We determined the formula for predicting ISD using multiple regression analysis.

Results
The mean ± standard deviation of the height, PAA, inlet-AP distance, mid-pelvis AP distance, outlet-AP distance, ISD, and ischial tuberosity distance were 160.0 ± 5.5 cm, 87.31 ± 6.6°, 129.7 ± 9.0 mm, 119.7 ± 8.5 mm, 111.71 ± 8.90 mm, 108.88 ± 8.0 mm, and 121.97 ± 11.8 mm, respectively. Two significant regression formulas for predicting ISD were identified as follows: ISD = 0.24973 × height − 0.06724 × inlet-AP distance + 0.12166 × outlet-AP distance + 0.29233 × ischial tuberosity distance + 0.32524 × PAA (P < 0.001, R2 = 0.9973 [adjusted R2 = 0.9973]) and ISD = 0.40935 × height + 0.49761 × PAA (P < 0.001, R2 = 0.9965 [adjusted R2 = 0.9965]).

Conclusion
ISD is the best predictor of obstructed labor. This study predicted ISD with 99% explanatory power using only the height and PAA. The PAA can be measured by transperineal ultrasound. This formula may successfully predict vaginal delivery or cephalopelvic disproportion.

An Emulated Clinical Trial of Deprescribing Proton Pump Inhibitors in Patients With Cirrhosis
Authors: Tapper Elliot B. , Zhao Zhe , Parikh Neehar D. 
Published: August 2023

INTRODUCTION:
Proton pump inhibitors (PPI) are overused and carry harms in cirrhosis. Deprescribing is advocated but has not been trialed.

METHODS AND FINDINGS:
We emulated a clinical trial using Medicare data. All patients were receiving chronic PPI therapy before a compensated cirrhosis diagnosis. We compared the risk death/decompensation over 3 years between continuous users and deprescribers. We find that PPI deprescription is associated with less ascites and that cumulative PPI use is associated with more ascites and encephalopathy. Ultimately, 71% of deprescribers restart PPIs.

DISCUSSION:
PPI deprescribing has benefits but requires ongoing support and alternative therapies for gastrointestinal symptoms.
Bibliotheksverbundkataloge in Argentinien
Authors: Tausch Arno 
Published: August 2023

Abstract
Der Beitrag diskutiert die beiden Verbundkataloge Argentiniens, UNIRED 30A und den Konkurrenzkatalog SIUBDU. Der UNIRED 30A integriert die Bibliotheksbestände von 109 Institutionen, darunter den wichtigsten Regierungsinstitutionen, Ministerialbibliotheken, Think-Tanks, Universitäten des Landes, Banken, Institutionen der lateinamerikanischen Wissenschaftsintegration wie FLACSO, CLACSO, INTAL und die Fundación Bariloche. Der SIUBDU integriert die Bestände von 56 Institutionen, darunter CLACSO und FLACSO und führende Universitäten des Landes aus allen Regionen. Um die Katalogentwicklung der in den beiden Bibliotheksverbunden integrierten wissenschaftlichen Bibliotheken zu testen, analysierte der Autor die Präsenz der Gewinner*innen des Skytte-Preises der internationalen Politikwissenschaft für die Jahre 2021, 2022 und 2023 in diesen Verbundkatalogen. Die Analyse zeigt, dass selbst bei sehr renommierten internationalen Politikwissenschaftler*innen ihre Bibliothekspräsenz in Lateinamerika äußerst gering ist und sich im Wesentlichen vor allem auf Werke bezieht, die von Ihnen in spanischer Sprache geschrieben wurden oder übersetzt worden sind.
Förderung von Informationskompetenz in Spezialbibliotheken unter Berücksichtigung von Wissenskulturen
Authors: Penner Tatjana 
Published: August 2023

Zusammenfassung
Lebenslange Weiterbildung der Informationskompetenz bei Wissenschaftler*innen ist unabdingbar und steht im Einklang mit der Steigerung der Forschungsproduktivität. Trotz dieser Erkenntnisse gibt es in der Fachliteratur bisher kaum nennenswerte Konzepte zur Förderung der Informationskompetenz dieser Zielgruppe. Die an der Forschungsbibliothek des Leibniz-Instituts für Bildungsmedien | Georg-Eckert-Institut durchgeführte wissenskulturelle Analyse zeigt, dass zur Förderung von Informationskompetenz ein ganzheitliches Konzept benötigt wird, welches sich nicht ausschließlich auf Rechercheschulungen beschränkt. Vor allem müssen verstärkt virtuelle Angebote integriert werden. Die im Folgenden aufgezeigte wissenskulturelle Analyse kann als Grundlage dienen, um ein neues Konzept zur Förderung der Informationskompetenz bei Wissenschaftler*innen zu entwickeln.
Women’s Experiences of Life Force Atrocities in the Baltic Ghettos, 1941–1944
Authors: Eglitis Daina S. 
Published: August 2023

Abstract
This article focuses on Jewish women in the Nazi ghettos of German-occupied Latvia and Lithuania. It uses testimonies and memoirs of survivors to develop a narrative about life force atrocities at these sites, highlighting ways in which being a Jewish woman shaped the experience of the ghettos, where gendered risks were ubiquitous. Being a woman in the ghettos meant being both exploited and undervalued as a source of physical labor, targeted as a potential or actual bearer of children, and violated as an object of racist and sexist ideology and rage. Life force atrocities have physical and symbolic dimensions, targeting bodies, bonds, and norms of the community. This work considers what women’s accounts tell us about the presence – or ubiquity – of life force atrocities in the Baltic ghettos. It draws on the concepts of the universe of obligation and social death to highlight key roots and consequences of these atrocities for women. In testimonies and memoirs, we encounter themes of pregnancy, forced abortion, the wrenching loss of loved ones, sexual violence, and decisions made in the desperate hope of saving oneself or another. Survivor accounts are key to revealing life force atrocities as defining features of the Nazi ghettos, and the gendered risks faced by women prisoners in Nazi-occupied Riga, Daugavpils, and Kaunas.
International Trade, Labor Flexibilization, and Wage Inequality: The Colombian Manufacturing Case
Authors: Hernández-Luna Yezid , Salazar-Pérez Camila , Herrera-Cuartas Jorge A. 
Published: August 2023

Abstract
This article delivers empirical evidence for the Colombian manufacturing sectors (during 1993–2012 and the subperiod 2000–2012) regarding the relationship between trade integration after the openness policy and the sector skill intensity over the skill premia, which depends on the Skill Biased Technical Change. We find that international trade reduces the positive sector skill intensity effect on wage inequality, moderately benefiting unskilled workers; however, a negative impact of the 1990 labor flexibilization on the skill premia, which increased the hiring of less expensive temporary and agency workers. Furthermore, the positive sector skill intensity impact on wage inequality is more important for trade with less developed countries than with the developed ones.
Computer technology of multisensor data fusion based on FWA–BP network
Authors: Hai Xiao 
Published: August 2023

Abstract
Due to the diversity and complexity of data information, traditional data fusion methods cannot effectively fuse multidimensional data, which affects the effective application of data. To achieve accurate and efficient fusion of multidimensional data, this experiment used back propagation (BP) neural network and fireworks algorithm (FWA) to establish the FWA–BP multidimensional data processing model, and a case study of PM2.5 concentration prediction was carried out by using the model. In the PM2.5 concentration prediction results, the trend between the FWA–BP prediction curve and the real curve was basically consistent, and the prediction deviation was less than 10. The average mean absolute error and root mean square error of FWA–BP network model in different samples were 3.7 and 4.3%, respectively. The correlation coefficient R value of FWA–BP network model was 0.963, which is higher than other network models. The results showed that FWA–BP network model could continuously optimize when predicting PM2.5 concentration, so as to avoid falling into local optimum prematurely. At the same time, the prediction accuracy is better with the improvement in the correlation coefficient between real and predicted value, which means, in computer technology of multisensor data fusion, this method can be applied better.
