Published: November 2023

IntroductionModern contraceptive use is important for improving health and socioeconomic outcomes, but Ethiopia is among the lowest-using countries. Therefore, this study aimed to determine factors affecting modern contraceptive use among women of reproductive age in Ethiopia.MethodsThis population-based cross-sectional study used data obtained from the 2019 Ethiopia Mini Demographic and Health Survey (EMDHS). A total of 8,885 reproductive-age women were included in the analysis. A weighted generalized estimating equation approach was used to account for the clustering and weighting effects in the assessment of associations between modern contraceptive usage and socioeconomic and demographic variables.ResultsModern contraceptive use among women of reproductive age in Ethiopia is low (28%). Prevalence is highest among women aged 25-34 (40.11%), with higher education (30.97%), who are Orthodox Christians (31.67%), married (40.40%), middle wealth index (31.70%), female-headed households (31.42%), with 1-3 living children (44.85%), who headed by under 31 years old (40.07%), and in the Amhara region (34.45%). In the generalized estimating equation analysis, women aged 35-44 and over 45, Muslims, households heads aged 41-50 and over 50, and in female-headed households were less likely to use modern contraceptives, while women with primary, secondary, and higher education, married, middle and rich wealth index, and with 1-3 and more living children were more likely to use modern contraceptive than their counterparts (reference group) and were statistically significant.ConclusionModern contraceptive use is notably low among women of reproductive age in Ethiopia. Factors such as age, women’s educational level, religion, marital status, number of living children, wealth status, gender and age of household head, and region were identified as significant factors associated with modern contraceptive use. Therefore, to increase modern contraceptive use, governmental and non-governmental organizations should invest in women’s education and financial empowerment and raise awareness about the benefits of modern contraceptives, especially among older, unmarried, financially poor, elderly-led households, with few living children, and uneducated women.
How well does NamSor perform in predicting the country of origin and ethnicity of individuals based on their first and last names?
Authors: Sebo Paul 
Published: November 2023

Background
We aimed to evaluate NamSor’s performance in predicting the country of origin and ethnicity of individuals based on their first/last names.

Methods
We retrieved the name and country of affiliation of all authors of PubMed publications in 2021, affiliated with universities in the twenty-two countries whose researchers authored ≥1,000 medical publications and whose percentage of migrants was <2.5% (N = 88,699). We estimated with NamSor their most likely "continent of origin" (Asia/Africa/Europe), "country of origin" and "ethnicity". We also examined two other variables that we created: “continent#2” ("Europe" replaced by "Europe/America/Oceania") and “country#2” ("Spain" replaced by “Spain/Hispanic American country” and "Portugal" replaced by "Portugal/Brazil"). Using "country of affiliation" as a proxy for "country of origin", we calculated for these five variables the proportion of misclassifications (= errorCodedWithoutNA) and the proportion of non-classifications (= naCoded). We repeated the analyses with a subsample consisting of all results with inference accuracy ≥50%.

Results
For the full sample and the subsample, errorCodedWithoutNA was 16.0% and 12.6% for “continent”, 6.3% and 3.3% for “continent#2”, 27.3% and 19.5% for “country”, 19.7% and 11.4% for “country#2”, and 20.2% and 14.8% for “ethnicity”; naCoded was zero and 18.0% for all variables, except for “ethnicity” (zero and 10.7%).

Conclusion
NamSor is accurate in determining the continent of origin, especially when using the modified variable (continent#2) and/or restricting the analysis to names with accuracy ≥50%. The risk of misclassification is higher with country of origin or ethnicity, but decreases, as with continent of origin, when using the modified variable (country#2) and/or the subsample.

Published: November 2023

Background
Satisfaction of fundamental needs is an important concept in sport, but currently there is no tool in Arabic to measure this construct. Basic needs are often linked to high rates of motivation and performance. It is necessary to develop tools to assess psychological needs in the sport context.

Aim
This study aimed to validate the Basic Needs Satisfaction in Sport Scale (BNSSS) in Arabic language across Tunisian athletes, and to test its psychometric properties (factorial structure, internal reliability, construct validity, and sensitivity).

Methods
Athletes in various sports participated in this study (370 men, 146 women; mean age 18.35) and voluntarily completed the Arabic version of the BNSSS-20. Both exploratory (EFA, N = 294; males: 68%; females: 32%; [14–18] = 182; [19–28] = 112) and confirmatory (CFA; N = 222; males: 76.6%; females: 23.4%; [14–18] = 103; [19–28] = 119) factor analyses were examined.

Results
Results from the EFA suggest that the BNSSS scale reflects the theoretical model well, with good internal consistency for all factors. All 20 items of BNSSS revealed excellent reliability (McDonald’s omega = 0.773, Cronbach’s α = 0.886, Gutmann’s λ6 = 0.970) and good temporal stability (ICC = 0.84, 95% CI = 0.55–0.93) over a 4-week period. Likewise, the CFA fit indices were excellent.

Conclusion
The BNSSS presented excellent fit to the theoretical model for all indices, confirming the factorial structure and providing validity of the instrument for Tunisian athletes.

Published: November 2023

Purpose
This study aimed to identify the association between physical activity and health-related quality of life (HRQoL) in middle-aged and elderly individuals with musculoskeletal disorders.

Methods
This study used data from the 2016–2020 Korea National Health and Nutrition Examination Survey (KNHANES). We included only those over 40 years of age diagnosed with one or more of the following: osteoarthritis, rheumatism, and osteoporosis. In total, 4,731 participants (783 men and 3,948 women) were included as the study population. Multiple logistic regression analysis was performed to examine the association between physical activity and HRQoL.

Results
In the case of middle-aged and elderly individuals with musculoskeletal disorders, the likelihood of HRQoL worsening was significantly lower for those who regularly engaged in physical activity compared with that of those who did not engage in physical activity at all (men: OR 0.58, 95% CI 0.37–0.90; women: OR 0.64, 95% CI 0.53–0.79). Stratified analysis by the type and intensity of physical activity revealed that the possibility of poor HRQoL was lowest when leisure-related moderate-intensity physical activities were performed (men: OR 0.44, 95% CI 0.22–0.89; Women: OR 0.50, 95% CI 0.36–0.69).

Conclusions
Our findings suggest that engaging in regular physical activity contributes to preventing exacerbation of HRQoL, even if the individual suffers from musculoskeletal disorders. It is necessary to provide an appropriate type and intensity of physical activity in consideration of the patients’ pain and severity.

Abstract
The fame of the Internet of vehicles (IOV) increases the complexity of managing the vast network of interconnected vehicles, devices, and systems, which causes the need for seamless connectivity among vehicles and infrastructure. Developing robust and efficient data transmission technologies is imperative to ensure that IOV functions smoothly and can not only handle the substantial volume of data generated by IOV but also address factors of latency, bandwidth, and scalability to meet the evolving demands of modern transportation systems. Therefore, experts are actively exploring novel solutions and advancements to tackle these challenges to promote IOV to new heights in transportation. In this survey paper, the authors surveyed the IOV of different architectures, provided a comprehensive overview of the Internet of things, vehicular ad hoc networks, and IOV networks, and compared the various networks. Similarly, they studied the multiple challenges of IOV and the corresponding solution available in recent literature. This paper describes the IOV evolution and examines several research papers related to the IOV and research guidance, such as high mobility, load balancing, security, heterogeneity, location accuracy, secure routing, etc.

AbstractWorking memory is an executive function that orchestrates the use of limited amounts of information, referred to as working memory capacity, in cognitive functions.Cannabisexposure impairs working memory in humans; however, it is unclear whetherCannabisfacilitates or impairs rodent working memory and working memory capacity. The conflicting literature in rodent models may be at least partly because of the use of drug exposure paradigms that do not closely mirror patterns of humanCannabisuse. Here, we used an incidental memory capacity paradigm where a novelty preference is assessed after a short delay in spontaneous recognition-based tests. Either object or odor-based stimuli were used in test variations with sets of identical [identical stimuli test (IST)] and different [different stimuli test (DST)] stimuli (three or six) for low-memory and high-memory loads, respectively. Additionally, we developed a human-machine hybrid behavioral quantification approach which supplements stopwatch-based scoring with supervised machine learning-based classification. After validating the spontaneous IST and DST in male rats, 6-item test versions with the hybrid quantification method were used to evaluate the impact of acute exposure to high-Δ9-tetrahydrocannabinol (THC) or high-CBDCannabissmoke on novelty preference. Under control conditions, male rats showed novelty preference in all test variations. We found that high-THC, but not high-CBD,Cannabissmoke exposure impaired novelty preference for objects under a high-memory load. Odor-based recognition deficits were seen under both low-memory and high-memory loads only following high-THC smoke exposure. Ultimately, these data show thatCannabissmoke exposure impacts incidental memory capacity of male rats in a memory load-dependent, and stimuli-specific manner.
The Precision of Place Fields Governs Their Fate across Epochs of Experience

AbstractSpatial memories are represented by hippocampal place cells during navigation. This spatial code is dynamic, undergoing changes across time, known as representational drift, and across changes in internal state, even while navigating the same spatial environment with consistent behavior. A dynamic code may provide the hippocampus a means to track distinct epochs of experience that occur at different times or during different internal states and update spatial memories. Changes to the spatial code include place fields (PFs) that remap to new locations and place fields that vanish, while others are stable. However, what determines place field fate across epochs remains unclear. We measured the lap-by-lap properties of place cells in mice during navigation for a block of trials in a rewarded virtual environment. We then determined the position of the place fields in another block of trials in the same spatial environment either separated by a day (a distinct temporal epoch) or during the same session but with reward removed to change reward expectation (a distinct internal state epoch). We found that place cells with remapped place fields across epochs tended to have lower spatial precision during navigation in the initial epoch. Place cells with stable or vanished place fields tended to have higher spatial precision. We conclude that place cells with less precise place fields have greater spatial flexibility, allowing them to respond to, and track, distinct epochs of experience in the same spatial environment, while place cells with precise place fields generally preserve spatial information when their fields reappear.

Aim. To study the dynamics of calculated indices [neutrophil-lymphocyte ratio (NLR); systemic inflammation index (SIV)] and biomarkers of systemic inflammation [interleukin-1β (IL-1β); high-sensitivity C-reactive protein (hsCRP)], parameters of the structure-and-function state of the myocardium and intracardiac hemodynamics, and their relationship in patients newly diagnosed with multiple myeloma (MM) at the onset of the disease and after 6 courses of chemotherapy (CT) containing the proteasome inhibitor bortezomib.Material and methods. This prospective study included 30 patients aged 63.8±10.0 years diagnosed with MM; 17 (56.7 %) of them were men. The following tests were performed for all patients: measurement of IL-1β and hsCRP, calculation of the inflammation indexes NLR and SIV, transthoracic echocardiography before and after 6 courses of bortezomib-containing CT. At the time of study completion, 9 patients dropped out due to reasons not related to cardiovascular complications of CT.Results. The antitumor therapy was associated with increases of immune-inflammation indexes: NLR increased from 1.54 [1.02; 1.83] to 2.9 [1.9; 4.35] (p=0.009) and SIV increased from 402.95 [230.5; 534.0] to 1102.2 [453.1; 1307.9] (р=0.014). IL-1β increased from 5.15 [4.05; 5.77] to 6.22 [5.66; 6.52] pg/ml remaining within the reference range (p=0.142) whereas hsCRP decreased from 1.02 [0.02; 2.71] to 0.02 [0.02; 0.82] IU/l (p=0.138). Statistically significant changes in parameters of heart remodeling and clinical picture of cardiovascular complications were not observed. A correlation analysis showed significant inverse correlations of hsCRP with left ventricular ejection fraction (LV EF) (r= –0.557; p=0.003), the number of plasma cells (PC) with LV EF (r= –0.443; p=0.023), and a direct correlation of the number of PC with hsCRP (r=0.433; p=0.022).Conclusion. During the study, the accepted criteria for cardiotoxicity of bortezomib-containing chemotherapy in patients with MM, were not met. The identified correlations between the level of markers for acute inflammation, indexes of intracardiac hemodynamics, and the immediate MM substrate may indicate the role of chronic low-intensity inflammation in the pathogenesis of myocardial remodeling in patients with MM. This necessitates further studies on larger samples of patients to assess the prognostic significance.

Abstract
Urban areas act as important shelters to support bee populations but some guilds, such as generalist species, are more benefited compared to others. We aimed to investigate if the floral preferences of a polylectic species would change throughout the years and if gardening practices as mowing could affect the females' floral preferences and, thus, the bee-plant interaction networks in an urban area within a medium-sized city in Brazil. Nesting females of Pseudaugochlora graminea (Fabricius) (Halictidae) were collected and had the pollen grains attached to their scopae removed, acetolysed and identified in two different periods: March 2019 and March 2022. Only five plant species were identified in samples from 2019 whilst 13 species were detected in 2022, in spite of mowing and plant replacements that occurred throughout this interval of three years. Among the floral sources observed, both exotic and native species were visited for pollen and nectar collection by the females. Despite being a generalist species, all interaction networks between P. graminea females and plant species were highly specialised. Females concentrated their pollen gathering on few plant species, which were represented by less than 10 individuals each at the study area. Mowing lead to the extirpation of the third most important pollen source in 2019 but plant replacements may have favoured females by some nectar sources seedlings. Our findings demonstrate that gardening practices impacted the floral choices by females of a generalist bee species and, consequently, their food webs.

Published: November 2023

Abstract

Prediction of treatment response by genetic biomarkers has potential for clinical use and contributes to the understanding of pathophysiology and drug mechanism of action. The purpose of this study is to identify genetic biomarkers associated with response to lurasidone, an atypical antipsychotic drug, during the first four weeks of treatment. One-hundred and seventy-one acutely psychotic patients from two placebo-controlled clinical trials of lurasidone were included. Genetic associations with changes in Positive and Negative Syndrome Scale total score at weeks one, two, and four were examined. Genotyping was done with the Affymetrix 6.0 microarray and associations were computed using PLINK regression model. Although genome-wide significance was not reached because of the small sample size, the top associations were with genes important for brain function. The top week one marker, rs6459950 (p = 7.05 × 10-7), was close to the sonic hedgehog gene (SHH), involved in neuronal differentiation and neurogenesis. The top week two marker, rs7435958, was a SNP of GABRB1, encoding the GABA A Receptor β1. Notably, week four markers included a SNP within PTCH1, a specific receptor for SHH, possibly involved in the week one response. Pathway enrichment analysis further supported the involvement of neuron differentiation and neurogenesis. Tissue enrichment analysis suggested enrichment of these genes in anterior cingulate cortex relevant to GABAergic modulation of neuronal connectivity. This is the first study to identify genes possibly associated with very early response to lurasidone. Further replication study is warranted and needed to determine the functional effects of the genetic markers.
