Published: March 2024

A distance education Diploma and Bachelor’s degree in Mathematics and Science programs are faced with low enrollment and graduation rate as well as high attrition of students. The aforementioned challenges are attributed to students’ satisfaction and continuance intention. However, students’ satisfaction and continuance intention toward distance education programs are as a result of certain antecedents. This modeled the determinants of satisfaction and program continuance intention by the distance education students on the math and science programs. Based on this, a quantitative approach based on a census survey was adopted and data collected from 113 students through a questionnaire and analyzed using a structural equation modeling approach based on partial least squares structural equation modeling (PLS-SEM). The results of the study showed that two key antecedents: student-instructor interaction, and study center physical facilities determine program satisfaction of mathematics and science distance students. However, administrative support of the program determined instructional modules; facilitation quality was predicted by both instructional modules and laboratory facilities. Finally, students program continuance intention was predicted by satisfaction of the program. Based on the findings, recommendations were made for policy and practice toward improving students’ satisfaction and promote positive intention in pursuant of mathematics and science education program by distance mode.
Resistance and Reconciliation of Children in George Eliot’s Novels
Authors: Jabeen Tahira
Published: March 2024

In 19th century England, fathers were considered the owner of the family estate where they were to decide everything regarding their children, but the children did not always welcome these decisions. This study uncovers, with the help of comprehensive and interdisciplinary supporting literary, social, and historical resources about and from the 19th century, Eliot’s presentation of the resistance of these children, the conflicts they have with their fathers, and finds out if the resistance of these children is justifiable in the context of the period. It also explores how these children come back to reconcile with their fathers emotionally and physically. It is concluded that all these children are inclined to leave home because they have conflicts with their fathers; however, they have to return to their roots, and therefore also to their fathers and embrace them. It is George Eliot’s belief that she keeps her characters attached to the family.
Digital Overload, Coping Mechanisms, and Student Engagement: An Empirical Investigation Based on the S-O-R Framework
Authors: Tafesse Wondwesen , Aguilar Mary Precy , Sayed Sabaa , Tariq Urwa
Published: March 2024

As avid users, university students find themselves immersed in the deluge of content being created and shared on digital platforms, which makes digital overload a significant concern. The present study examines the effects of digital overload on university students’ psychological well-being and how the use of coping mechanisms might help to mitigate some of these effects. The study developed a research model based on the S-O-R (stimulus, organism, response) framework and gathered data from undergraduate students at a major public university in the United Arab Emirates. To minimize the threat of common method bias, data collection was conducted in two rounds separated by two weeks. Hypotheses were tested using a partial least square path modeling approach. The findings show that digital overload causes psychological strains among students such as technostress and exhaustion, which subsequently encourage them to adopt coping mechanisms. The findings also show that the adoption of coping mechanisms is positively associated with student engagement. The study contributes to the literature by shifting the focus away from information overload—emphasizing digital overload instead—and investigating how students can respond to it by using coping mechanisms.
What Is the Role of Affective Cognition in Trauma and Posttraumatic-Stress-Disorder-Related Drinking? A Systematic Review
Authors: Zaso Michelle J. , Troidl Ian R. , Read Jennifer P.
Published: March 2024

Trauma and posttraumatic stress disorder (TR/PTSD) are implicated in deleterious alcohol outcomes, yet the processes that undergird these associations remain elusive. Affective (i.e., emotionally laden) cognitions may play key roles in TR/PTSD-related drinking that could inform prevention and intervention. In the present review, we synthesized extant literature ( k = 58) on affective cognitions and their role in negative- and positive-reinforcement TR/PTSD-related drinking, including alcohol-specific (e.g., drinking motives, alcohol expectancies) and non-alcohol-specific (e.g., emotion-regulation cognitions, perception and attentional biases) cognitions. Findings generally supported the importance of alcohol-specific cognitions in negative-reinforcement drinking more so than positive-reinforcement drinking. Non-alcohol-specific affective cognitions were considerably less researched. Several gaps in the knowledge base emerged; studies were overwhelmingly cross-sectional, conducted mainly within homogeneous college samples, and often did not disaggregate effects of trauma exposure from those of PTSD. Future research is needed to address these gaps to optimally inform clinical efforts to reduce TR/PTSD-related drinking risk.

Authors: Gill Ashlinder , Meadows Lynn , Ashbourne Jessica , Kaasalainen Sharon , Shamon Sandy , Pereira José
Published: March 2024

Objective:

To explore the impact of a 2-day, in-person interprofessional palliative care course for staff working in long-term care (LTC) homes.

Methods:

A qualitative descriptive study design was employed. LTC staff who had participated in Pallium Canada’s Learning Essential Approaches to Palliative Care LTC Course in Ontario, Canada between 2017 and 2019 were approached. Semi-structured interviews were conducted, using an online videoconferencing platform in mid-2021 in Ontario, Canada. These were done online, recorded, and transcribed. Data were coded inductively.

Results:

Ten persons were interviewed: four registered practical nurses, three registered nurses, one nurse practitioner, and two physicians. Some held leadership roles. Participants described ongoing impact on themselves and their ability to provide end-of-life (EOL) care (micro-level), their services and institutions (meso-level), and their healthcare systems (macro-level). At a micro-level, participants described increased knowledge and confidence to support residents and families, and increased work fulfillment. At the meso-level, their teams gained increased collective knowledge and greater interprofessional collaboration to provide palliative care. At the macro level, some participants connected with other LTC homes and external stakeholders to improve palliative care across the sector. Training provided much-needed preparedness to respond to the impact of the COVID-19 pandemic, including undertaking advance care planning and EOL conversations. The pandemic caused staff burnout and shortages, creating challenges to applying course learnings.

Significance of results:

The impact of palliative care training had ripple effects several years after completing the training, and equipped staff with key skills to provide care during the COVID-19 pandemic. Palliative care education of staff remains a critical element of an overall strategy to improve the integration of palliative care in LTC.
Gbdmr: identifying differentially methylated CpG regions in the human genome via generalized beta regressions
Authors: Wu Chengzhou , Mou Xichen , Zhang Hongmei
Published: March 2024

Background

DNA methylation is a biochemical process in which a methyl group is added to the cytosine-phosphate-guanine (CpG) site on DNA molecules without altering the DNA sequence. Multiple CpG sites in a certain genome region can be differentially methylated across phenotypes. Identifying these differentially methylated CpG regions (DMRs) associated with the phenotypes contributes to disease prediction and precision medicine development.

Results

We propose a novel DMR detection algorithm, gbdmr. In contrast to existing methods under a linear regression framework, gbdmr assumes that DNA methylation levels follow a generalized beta distribution. We compare gbdmr to alternative approaches via simulations and real data analyses, including dmrff, a new DMR detection approach that shows promising performance among competitors, and the traditional EWAS that focuses on single CpG sites. Our simulations demonstrate that gbdmr is superior to the other two when the correlation between neighboring CpG sites is strong, while dmrff shows a higher power when the correlation is weak. We provide an explanation of these phenomena from a theoretical perspective. We further applied the three methods to multiple real DNA methylation datasets. One is from a birth cohort study undertaken on the Isle of Wight, United Kingdom, and the other two are from the Gene Expression Omnibus database repository. Overall, gbdmr identifies more DMR CpGs linked to phenotypes than dmrff, and the simulated results support the findings.

Conclusions

Gbdmr is an innovative method for detecting DMRs based on generalized beta regression. It demonstrated notable advantages over dmrff and traditional EWAS, particularly when adjacent CpGs exhibited moderate to strong correlations. Our real data analyses and simulated findings highlight the reliability of gbdmr as a robust DMR detection tool. The gbdmr approach is accessible and implemented by R on GitHub: https://github.com/chengzhouwu/gbdmr.

Published: March 2024

Objectives

The black rhinoceros (Diceros bicornis) is an endangered mammal for which a captive breeding program is part of the conservation effort. Black rhinos in zoo’s often suffer from chronic infections and heamochromatosis. Furthermore, breeding is hampered by low male fertility. To aid a research project studying these topics, we sequenced and assembled the genome of a captive male black rhino using ONT sequencing data only.

Data description

This work produced over 100 Gb whole genome sequencing reads from whole blood. These were assembled into a 2.47 Gb draft genome consisting of 834 contigs with an N50 of 29.53 Mb. The genome annotation was lifted over from an available genome annotation for black rhino, which resulted in the retrieval of over 99% of gene features. This new genome assembly will be a valuable resource in for conservation genetic research in this species.

Keywords

Black rhinoceros, Diceros bicornis, Genome assembly, Long reads, Whole genome sequencing.

Published: March 2024

Background

Panax notoginseng (Burk) F. H. Chen is one of the most famous Chinese traditional medicinal plants. The taproot is the main organ producing triterpenoid saponins, and its development is directly linked to the quality and yield of the harvested P. notoginseng. However, the mechanisms underlying the dynamic metabolic changes occurring during taproot development of P. notoginseng are unknown.

Results

We carried out metabolomic and transcriptomic analyses to investigate metabolites and gene expression during the development of P. notoginseng taproots. The differentially accumulated metabolites included amino acids and derivatives, nucleotides and derivatives, and lipids in 1-year-old taproots, flavonoids and terpenoids in 2- and 3-year-old taproots, and phenolic acids in 3-year-old taproots. The differentially expressed genes (DEGs) are related to phenylpropanoid biosynthesis, metabolic pathway and biosynthesis of secondary metabolites at all three developmental stages. Integrative analysis revealed that the phenylpropanoid biosynthesis pathway was involved in not only the development of but also metabolic changes in P. notoginseng taproots. Moreover, significant accumulation of triterpenoid saponins in 2- and 3-year-old taproots was highly correlated with the up-regulated expression of cytochrome P450s and uridine diphosphate-dependent glycosyltransferases genes. Additionally, a gene encoding RNase-like major storage protein was identified to play a dual role in the development of P. notoginseng taproots and their triterpenoid saponins synthesis.

Conclusions

These results elucidate the molecular mechanism underlying the accumulation of and change relationship between primary and secondary metabolites in P. notoginseng taproots, and provide a basis for the quality control and genetic improvement of P. notoginseng.

Published: March 2024

Background

Parkinson’s Disease (PD) is the second most common progressive neurodegenerative disorder, mostly affecting balance and motor function caused mainly by a lack of dopamine in the brain. The use of virtual reality (VR) and motor imagery (MI) is emerging as an effective method of rehabilitation for people with Parkinson’s disease. Motor imagery and virtual reality have not been compared in patients with Parkinson’s disease. This randomized clinical trial is unique to compare the effects of virtual reality with routine physical therapy, motor imagery with routine physical therapy, and routine physical therapy alone on balance, motor function, and activities of daily living in patients with Parkinson’s disease.

Methods

A total of sixty patients with Parkinson’s disease were randomized into three groups using lottery method; twenty with virtual reality therapy in addition to physical therapy (group A = VR + RPT), twenty with imagery therapy in addition to physical therapy (group B = MI + RPT), and twenty were treated with only routine physical therapy (group C = RPT). All patients were evaluated using the Unified Parkinson’s Disease Rating Scale (UPDRS) for motor function and activities of daily living, the Berg balance scale (BBS) for balance, and the Activities-specific Balance Confidence Scale (ABCs) for balance confidence at baseline, six and twelve weeks, and one month after treatment discontinuation. The one-way ANOVA was used to compare the outcomes between three groups, and the repeated measures ANOVA was used to compare the outcomes within each of the three groups at a significance level of p-value = 0.05.

Results

According to UPDRS III, the VR + RPT group showed significant improvement in motor function, compared to the MI + RPT and RPT groups, as the Mean ± SD at baseline was 33.95 ± 3.501 and at the 12-week assessment was 17.20 ± 9.451 with a p-value = 0.001. In the VR + RPT group, the BBS score at baseline was 37.15 ± 3.437 and at 12th week was 50.10 ± 4.897 with a p-value = 0.019. Among the VR + RPT group, the ABCS score showed significant improvement as the M ± SD at baseline was 57.95 ± 4.629, and at the 12th week was 78.59 ± 6.386 with a p-value = 0.010. At baseline, the UPDRS II for activities of daily living in the VR + RPT group was 25.20 ± 3.036 and at 12th week it was 15.30 ± 2.364 with p-value of 0.000.

Conclusion

The current study found that the combination of VR and RPT proved to be the most effective treatment method for improving balance, motor function, and activities of daily living in patients with Parkinson’s disease when compared to MI + RPT or RPT alone.
Development of a prediction model for facilitating the clinical application of transcranial color-coded duplex ultrasonography
Authors: Duan Jieyu , Wang Pengfei , Wang Haoyu , Zhao Wei
Published: March 2024

Background

Transcranial color-coded duplex ultrasonography (TCCD) is an important diagnostic tool in the investigation of cerebrovascular diseases. TCCD is often hampered by the temporal window that ultrasound cannot penetrate. Rapidly determine whether ultrasound can penetrate the temporal window in order to determine whether to use other acoustic windows to complete the examination process. In this study, Skull thickness can be measured simultaneously during TCCD examination, which makes it possible to use skull thickness to rapidly determine whether the temporal window is penetrated by ultrasound.

Methods

This retrospective study included 301 patients with clinical symptoms of cerebrovascular diseases. These 301 patients were divided into an impenetrable temporal window (ITW) group and a penetrable temporal window group according to the results of the TCCD examination.

Results

The area under the receiver operating characteristic (ROC) curve (AUC) for skull thickness was 0.887 (cutoff value 1.045 cm). Following multivariate logistic regression, sex, age, and skull thickness were used to develop a nomogram. The AUC for the nomogram was 0.923 (cutoff value 0.407).

Conclusions

The skull thickness at the temporal window was measured by ultrasound, which was convenient and accurate. The probability of ITW in females was higher than that in males, and it increased with age. In this study, a prediction model incorporating sex, age and skull thickness could predict ITW probability well. If the patient’s temporal window was rapidly predicted as an ITW, other acoustic window examinations were used to complete the TCCD examination process to optimize the TCCD examination process of cerebrovascular diseases and facilitate the popularization of TCCD in clinical application.

Authors: Tang Jing , Wang Dongxue , Chen Yun , Feng Jinhong
Published: March 2024

Objective

To validate an association between new inflammation and frequent peritoneal dialysis-associated peritonitis (PDAP).

Materials and methods

In China, retrospective clinical data were collected on 208 patients who received continuous ambulatory peritoneal dialysis (CAPD) between 2010 and 2021. The patients were divided into two groups: non-frequent PDAP (the interval between two peritonitis episodes of more than one year) and frequent PDAP (the interval between two peritonitis episodes of less than one year). Patients with their first episode of peritonitis had their age, gender, history of hypertension, diabetic disease, underlying renal disease, bacterial infection, and laboratory data collected. The outcomes of bacterial dispersion, systemic immune-inflammation index (SII), high-density lipoprotein cholesterol (HDL-C), C-reactive protein (CRP), and risk variables associated with frequent PDAP were analyzed.

Results

There are differences between the two groups in dialysis time (p = 0.006), hypertensive nephropathy (p = 0.038), staphylococcus (p = 0.035), white blood cells (p = 0.001), neutrophil (p < 0.01), lymphocyte (p < 0.01), platelet(p = 0.01), SII(p < 0.01), CRP/HDL-C (p = 0.002), CRP (p < 0.001), serum creatinine (p = 0.007), blood urea nitrogen (p = 0.05), serum magnesium (0.03), serum potassium (p = 0.007), and dialysate polymorphonuclear cells (p = 0.004). Multifactorial logistic regression analysis found that SII (p < 0.001), CRP/HDL-C (p = 0.041), and Diabetes mellitus (p = 0.027) were independent risk factors for frequent PDAP. The ROC curve analysis revealed that combining SII with CRP/HDL-C resulted in the largest AUC area (AUC = 0.814).

Conclusions

Our findings offer clinical proof of the combination of SII and CRP/HDL-C in patients with frequent PDAP.
Adherence to the evidence-based recommendations in managing bone health, pain, and mobility of patients with multiple myeloma: a mixed method in the Palestinian healthcare system
Authors: Shawahna Ramzi , Amer Riad , Salameh Husam , Shawahna Abdul-Rahman , Aljondy Mohmmad , Zain-Aldain Mohmmad
Published: March 2024

Background

Consensus/evidence-based recommendations for assessing, managing, and monitoring bone health, pain, and mobility in patients with multiple myeloma were developed. This study was conducted to assess the adherence of the hematologists-oncologists to the consensus/evidence-based recommendations for assessing, managing, and monitoring bone health, pain, and mobility in patients with multiple myeloma who received care in the Palestinian healthcare system.

Methods

A mixed method was used in this study. The consensus/evidence-based recommendations were identified through a systematic search in Scopus, PubMed, SpringerLink, ScienceDirect, and Google Scholar. A panel of 5 researchers (3 hematologists-oncologists, 3 medical students, and 1 pharmacologist) sorted the consensus/evidence-based recommendations and developed the survey tool during 3 iterative meetings. The extent to which the hematologists-oncologists in the 5 centers caring for patients with multiple myeloma adhered to the consensus/evidence-based recommendations was assessed using a questionnaire.

Results

Responses were collected from 10 hematologists-oncologists in all 5 healthcare centers where patients with multiple myeloma receive healthcare in the West Bank of Palestine. The median number of years in the practice of the hematologists-oncologists was 7.5 [2.75, 14.0] years and the median number of patients with multiple myeloma care per month was 12.5 [7.5, 21.25]. The vast majority (90%) of the hematologists-oncologists reported inadequate adherence to screening for medication problems related to bone health, pain, cardiopulmonary fitness, healthy behaviors, nutritional deficits, and mental health. Of the hematologists-oncologists, 70% reported inadequate adherence to ordering and evaluating calcium, vitamin D, alkaline phosphatase, electrolytes, and phosphorus levels to monitor bone health and 60% reported inadequate adherence to prescribing calcium and vitamin D supplements whenever there was a need.

Conclusion

The findings of this study suggested inadequate adherence to the consensus/evidence-based recommendations and highlighted areas for improvement to ensure that patients receive optimal care. The findings suggested a need for further education and training on the latest guidelines and recommendations. Decision-makers and policymakers might need to design measures and implement policies to improve adherence to the consensus/evidence-based recommendations. Addressing these gaps in adherence to the consensus/evidence-based recommendations may improve the care and outcomes of patients with multiple myeloma.
Potential causal associations between leisure sedentary behaviors, physical activity, sleep traits, and myopia: a Mendelian randomization study
Authors: Zhang Xiao-Bin , Jiang He-He , Zhang Lin-Lin , Li Chun-Jing , Chen Chen , Xing Meng-Zhen , Ma Yu-Ning , Ma Yu-Xia
Published: March 2024

Background

Myopia is the most prevalent refractive error and a growing global health concern that significantly affects visual function. Researchers have recently emphasized considerably on the influence of lifestyle on myopia incidence and development. This study investigates the relationship between leisure sedentary behaviors (LSB)/physical activity (PA)/sleep traits and myopia.

Methods

LSB, PA, and sleep trait-associated genetic variants were used as instrument variables in a Mendelian randomization (MR) study to examine their causal effects on myopia. Summary genome-wide association studies (GWASs) statistical data for LSB and PA were obtained from UK Biobank, and the data of sleep traits was obtained from UK Biobank, UK Biobank and 23andMe, and FinnGen. We used summary statistics data for myopia from MRC IEU. The MR analyses was performed using the inverse variance-weighted (IVW), MR-Egger, weighted median, and MR Pleiotropy RESidual Sum and Outlier methods.

Results

Computer use was genetically predicted to increase the myopia risk [IVW odds ratio (OR) = 1.057; 95% confidence interval (CI), 1.038–1.078; P = 7.04 × 10− 9]. The self-reported moderate-to-vigorous physical activity (MVPA) (IVW OR = 0.962; 95% CI, 0.932–0.993; P = 1.57 × 10− 2) and television watching (IVW OR = 0.973; 95% CI, 0.961–0.985, P = 1.93 × 10− 5) were significantly associated with a lower myopia risk. However, genetically predicted sleep traits or accelerometer-measured physical activity had no significant associations with myopia.

Conclusion

Our results indicated that computer use is a risk factor for myopia, whereas television watching and MVPA may protect against myopia. These findings shed new light on possible strategies for reducing the prevalence of myopia.
Novel surgical approaches for treating myopic traction maculopathy: a meta-analysis
Authors: Quiroz-Reyes Miguel A. , Quiroz-Gonzalez Erick A. , Quiroz-Gonzalez Miguel A. , Lima-Gomez Virgilio
Published: March 2024

Background

Myopic traction maculopathy (MTM) is a complication of pathological myopia and encompasses various pathological conditions caused by tractional changes in the eye. These changes include retinoschisis, foveal retinal detachment, and lamellar or full-thickness macular holes (FTMHs). This meta-analysis evaluated the safety and efficacy of novel surgical for treating MTM.

Methods

To compare the outcomes of different surgical approaches for MTM, multiple databases, including Web of Science, PubMed, Scopus, ClinicalTrials.gov, the Cochrane Central Register of Controlled Trials, Ovid MEDLINE, Embase, and the Meta-Register of Controlled Trials, were comprehensively searched. The meta-analysis was performed using RevMan 5.1.

Results

Nine comparative studies involving 350 eyes were included in this meta-analysis. There were significant differences between fovea-sparing internal limiting membrane peeling (FSIP) and standard internal limiting membrane peeling (ILMP). Preoperative best-corrected visual acuity BCVA (standard mean difference (SMD): -0.10, 95% CI: -0.32 to 0.12) and central foveal thickness CFT (SMD: 0.05, 95% CI: -0.22 to 0.33) were not significantly different (p = 0.39 and p = 0.71, respectively). However, the postoperative BCVA improved significantly (SMD = − 0.47, 95% CI: − 0.80, − 0.14, p = 0.006) in the FSIP group compared to the standard ILMP group. Postoperative CFT did not differ significantly between the two groups (p = 0.62). The FSIP group had a greater anatomical success rate than the other groups, although the difference was not statistically significant (p = 0.26). The incidence of postoperative macular hole formation was significantly lower (OR = 0.19, 95% CI = 0.07–0.54; p = 0.05) in the FSIP group than in the standard ILMP group. The unique characteristics of highly myopic eyes, such as increased axial length and structural changes, may have contributed to the greater incidence of FTMH in the ILMP group.

Conclusion

Based on the findings of this meta-analysis, FSIP is the initial surgical approach for early-stage MTM and has shown promising outcomes. However, to establish the safest and most efficient surgical technique for treating different MTM stages, further comparative studies, specifically those focusing on ILMP and FSIP, are necessary.

Association between handgrip strength and depressive symptoms in patients undergoing hemodialysis: a cross-sectional study from a single Chinese center
Authors: Zhang Shuang , Liu Shu-Xin , Wu Qi-Jun , Wang Zhi-Hong , Liu Hong , Xiao Ping , Lu Yan , Dong Cui , Meng Qing-Mei
Published: March 2024

Background

The relationship between handgrip strength (HGS) and depression in patients undergoing hemodialysis (HD) was unknown. Therefore, we aimed to clarify this association in a cohort of patients.

Methods

HGS was used as a representative indicator of muscle strength and was measured with a handheld dynamometer. Depressive symptoms were assessed with the self-reported Patient Health Questionnaire-9. A multivariable logistic regression model and restricted cubic spline analysis were used to assess the relationship between HGS and depression.

Results

The prevalence of depression in our study was 34% in 568 Chinese patients undergoing HD. Compared with patients in the lowest tertiles of absolute and weighted HGS, patients in the highest tertiles of HGS had an approximately 59% lower [odds ratio (OR) = 0.41, 95% confidence interval (CI) = 0.24–0.68; OR = 0.41, 95%CI = (0.24–0.69)] prevalence of depressive symptoms after multivariate adjustments. Besides, the risk of depression in hemodialysis patients decreased by 33% (OR = 0.67, 95%CI = 0.53–0.85) and 32% (OR = 0.68, 95%CI = 0.54–0.85) for each standard deviation increase in absolute HGS and weighted HGS, respectively. The prevalence of depressive symptoms decreased with both increasing absolute HGS and weighted HGS after multivariate adjustments (p for trend < 0.05). Furthermore, a linear dose-response relationship was observed between absolute HGS and weighted HGS and the prevalence of depressive symptoms (pnonlinearity>0.05).

Conclusions

This study suggests that lower handgrip strength, a simple and modifiable parameter, is associated with a higher prevalence of depression in Chinese patients undergoing HD. Considering that depression is often unrecognized or underdiagnosed in HD patients, lowered muscle strength should be an important indicator and incentive for medical staff to screen for depression.

Authors: Zuo Chongwen , Zheng Zhiyang , Ma Xiaoyan , Wei Fen , Wang Yushui , Yin Yi , Liu Shuai , Cui Xiaosong , Ye Chaoqun
Published: March 2024

Background

Chronic low back pain (LBP) related to flight is a prevalent health issue in military aviation, impacting pilots. The objective of this investigation was to ascertain if the application of core muscle training in conjunction with interferential current (IFC) therapy results in a reduction in pain severity and associated disability, consequently enhancing core muscle functionality in Chinese Air Force high-performance fighter pilots experiencing chronic LBP.

Methods

Fifty-three fighter pilots with chronic LBP were randomized into 3 groups: a core muscle exercise combined with IFC group (CG, n = 19), a core muscle exercise group (EG, n = 19), and an IFC group (IG, n = 15). The three groups underwent therapeutic intervention 5 times a week for 12 weeks. The primary outcomes were pain intensity, Oswestry Disability Index (ODI) score and SF-12 health-related quality of life (PCS and MCS) score. Secondary outcomes included evaluations of trunk muscle strength, endurance, and range of motion (ROM) during medial/lateral rotation to assess muscle functionality. Measurements were obtained both before and after the implementation of the intervention therapy.

Results

After 12 weeks of intervention therapy, all the health condition parameters significantly improved among the three groups. However, the CG had a significant improvement in pain intensity compared to the EG (MD = − 0.84 scores; 95% CI = − 1.54 to − 0.15; p = 0.013) and the IG (MD = − 1.22 scores; 95% CI = − 1.96 to − 0.48; p = 0.000). Additionally, the CG led to greater conservation of ODI and improved SF-12 PCS scores than did the IG (p < 0.05). Finally, compared with those at baseline, the core muscle function parameters in the CG and EG improved significantly at the end of the study, but no statistically significant differences were observed between the two groups (p > 0.05).

Conclusion

Among participants with chronic LBP, three intervention therapies appear effective in reducing pain, diminishing disability, and enhancing quality of life. Also, combined therapy significantly improved pain and disability compared to the other two monotherapies; moreover, combined therapy and core muscle exercise provided similar benefits in terms of core muscle function after 12 weeks of intervention therapy.
Predictors of quitting support from nonsmoking mothers for smoking fathers: a cross-sectional study from Chinese pupils’ families
Authors: Jiang Nan , Huo Ling-ling , Zhang Zeng-zhi , Huang Yi-qing , Li Yu-hua , Wang Rui , Guo Yi , Qi Fei , Li Shan-peng
Published: March 2024

Background

Quitting support from smokers’ partners can predict quit attempts and smoking abstinence but research on factors that predict such support has been limited. To add more evidence for partner support and the improved interventions for smoking cessation, we analyzed some new potential predictors of quitting support from smokers’ spouses.

Method

This cross-sectional study was conducted in in 2022 and 2023, selecting the students’ families in which fathers smoked and mothers didn’t smoke from grade 1–5 of 13 primary schools in Qingdao, China. Parents who met the criteria completed the online questionnaires and 1018 families were included in the analysis. We measured personal information related to smokers and their spouses such as age, education and nicotine dependence, and variables related to family and marital relationship such as family functioning, perceived responsiveness and power in decision-making of quitting smoking. Quitting support from smokers’ spouses was measured by Partner Interaction Questionnaire and generalized linear model was used to explore the potential predictors of partner support.

Results

In this study, the mean age of smokers was 39.97(SD = 5.57) and the mean age of smokers’ spouses was 38.24(SD = 4.59). The regression analysis showed that for smokers and their spouses, the older age groups showed the lower ratio of positive/negative support(P < 0.05) and smokers with high education showed the less positive and negative partner support(P < 0.05). Nicotine dependence was positively associated with negative support (β = 0.120, P < 0.01), and perceived responsiveness (β = 0.124, P < 0.05) as well as family functioning (β = 0.059, P < 0.05) was positively associated with positive support. These three factors were associated with ratio of positive/negative support(P < 0.05). In addition, power of smoker’s spouse in decision-making of quitting smoking was positively associated with the positive (β = 0.087, P < 0.001) and negative support (β = 0.084, P < 0.001).

Conclusions

Nicotine dependence, family functioning, power in decision-making of quitting smoking and perceived responsiveness were found to be the predictors of quitting support from smokers’ spouses. By incorporating predictors of partner support and integrating some established theories that can improve family functioning and marital relationships, smoking cessation interventions can be further improved.

Authors: Wu Junpeng , Yang Panpan , Wu Xiaodan , Yu Xiaoxuan , Zeng Fanfang , Wang Haitang
Published: March 2024

Background

Opioid crisis has become a global concern, but whether physical activity (PA) can effectively reduce prescription opioid use remains unclear. The study aimed to examine the relationship of different domains of PA (e.g., occupation-related PA [OPA], transportation-related PA [TPA], leisure-time PA [LTPA]) with prescription opioid use and duration of prescription opioid use.

Methods

This cross-sectional study was conducted on 27,943 participants aged ≥ 18 years from National Health and Nutrition Examination Survey (NHANES, 2007– March 2020). We examined the relationship of different domains of PA with prescription opioid use and duration of prescription opioid use using multivariable logistic regression. Stratified analysis and a series of sensitivity analysis were used to elevate robustness. All analyses were conducted using appropriate sampling weights.

Results

Of the 27,943 participants, the mean age was 45.10 years, with 14,018 [weighted, 50.0%] females and 11,045 [weighted, 66.0%] non-Hispanic White. After multivariable adjustment, inverse associations between PA and prescription opioid use were observed for sufficient (≥ 150 min/week) total PA (OR,0.68 95%CI [0.56–0.81]), TPA (OR,0.73 95%CI [0.58–0.92]), and LTPA (OR,0.60 95%CI [0.48–0.75]) compared with insufficient PA(< 150 min/week), but not for sufficient OPA (OR,0.93 95%CI [0.79–1.10]). In addition, the associations were dose-responsive, participants had 22–40%, 27–36%, and 26–47% lower odds of using prescription opioids depending on the duration of total PA, TPA, and LTPA, respectively. Nevertheless, the impact of PA on prescription opioid use varied by duration of opioid use. Sufficient total PA was associated with elevated odds of short-term use of prescription opioids (< 90 days). Comparatively, sufficient total PA, TPA, and LTPA had different beneficial effects on reducing long-term use of prescription opioids (≥ 90 days) depending on the strength of opioids.

Conclusions

This study demonstrated sufficient total PA, TPA, and LTPA were inversely associated with prescription opioid use and varied depending on the duration and strength of prescription opioid use. These findings highlight PA can provide policy guidance to address opioid crisis.
Becoming a doctor: using social constructivism and situated learning to understand the clinical clerkship experiences of undergraduate medical students
Authors: Cho Hyena , Jeong Hyeyoon , Yu Jihye , Lee Janghoon , Jung Hyun Joo
Published: March 2024

Background

Despite the emphasis on the uniqueness and educational importance of clinical clerkships in medical education, there is a lack of deep understanding of their educational process and outcomes. Especially due to an inherent trait of clinical clerkships which requires participation in the workplace outside the classroom, it is difficult to fully comprehend their educational potential using traditional learning perspectives such as imbibing outside knowledge. Accordingly, this study aims to explore the experiences of a rotation-based clerkship of medical school students from the perspective of social constructivism of learning, which can empirically examine what and how medical students learn during clinical clerkship in South Korea. By providing an insight into the workings of the clerkship process, this study contributes to a better understanding of how a learning-friendly environment can be cultivated at clinical clerkships.

Methods

The study utilized a basic qualitative study to understand what and how medical students learn during their clinical clerkships. Semi-structured, in-depth individual interviews were conducted with eight sixth-graders who had experienced a two-year clerkship at Ajou University Medical School. Data were analyzed based on Lave and Wenger’s situated learning theory and Wenger’s social theory in learning.

Results

We found that the medical students had developed different aspects of their professional identities such as values, functionality, career decisions, sociality, and situating during their clinical clerkships. Further, professional identity was formed through a combination of participation and reification—the processes involved in the negotiation of meaning. This combination was facilitated by the students’ first experience and relationships with professors, classmates, and patients. Finally, non-learning occurred in the context of over-participation (learning anxiety and alienation) or over-reification (evaluation and e-portfolio).

Conclusions

This study revealed five sub-professional identities and their formation process from the learners’ perspective, thereby uncovering the unique learning characteristics and advantages of rotated-based clerkship and contributing to a further understanding of how gradual improvements can be made to the traditional clerkship education of medical students.

Published: March 2024

Background

In healthcare, inadequate communication among providers and insufficient information transmission represent primary contributors to adverse events, particularly in medical specialties such as obstetrics and gynecology. The implementation of SBAR (Situation-Background-Assessment-Recommendation) has been proposed as a standardized communication tool to enhance patient safety. This study aims to evaluate the knowledge, attitudes, and practices related to SBAR communication through a pilot study conducted in a middle-income country.

Methods

This prospective longitudinal study took place in the gynecology-obstetrics department of a Tunisian university hospital from May to June 2019. All medical and paramedical staff underwent comprehensive theoretical and practical training through a 4-hour SBAR simulation. To gauge participants’ knowledge, anonymous multiple-choice questionnaires were administered before the training initiation, with a second assessment conducted at the end of the training to measure satisfaction levels. Two months later, the evaluation utilized questionnaires validated by the French National Authority for Health (HAS).

Results

Among the 62 care staff participants in this study, a majority (89%) demonstrated a low level of knowledge regarding the SBAR tool. The majority (75.8%) expressed enjoyment with the training and indicated their intention to implement changes in their practice by incorporating the SBAR tool in the future (80.7%). Notably, over half of the participants (79%) expressed satisfaction with the training objectives, and 74% reported acquiring new information. Evaluation of the practice revealed positive feedback, particularly in terms of clarity, the relevance of communication, and the time spent on the call.

Conclusion

Our pilot study showed that the majority of professionals on the ward had little knowledge of the SBAR tool, a good attitude and a willingness to put it into practice. It is essential that healthcare managers and professionals from all disciplines work together to ensure that good communication practice is developed and maintained. Organisations, including universities and hospitals, need to invest in the education and training of students and health professionals to ensure good quality standardised communication.

Authors: Escobar Díaz Guerrero Rodrigo , Oliveira José Luis , Popp Juergen , Bocklitz Thomas
Published: March 2024

Background

Multimodal histology image registration is a process that transforms into a common coordinate system two or more images obtained from different microscopy modalities. The combination of information from various modalities can contribute to a comprehensive understanding of tissue specimens, aiding in more accurate diagnoses, and improved research insights. Multimodal image registration in histology samples presents a significant challenge due to the inherent differences in characteristics and the need for tailored optimization algorithms for each modality.

Results

We developed MMIR a cloud-based system for multimodal histological image registration, which consists of three main modules: a project manager, an algorithm manager, and an image visualization system.

Conclusion

Our software solution aims to simplify image registration tasks with a user-friendly approach. It facilitates effective algorithm management, responsive web interfaces, supports multi-resolution images, and facilitates batch image registration. Moreover, its adaptable architecture allows for the integration of custom algorithms, ensuring that it aligns with the specific requirements of each modality combination. Beyond image registration, our software enables the conversion of segmented annotations from one modality to another.
The role of the nursing work environment, head nurse leadership and presenteeism in job embeddedness among new nurses: a cross-sectional multicentre study
Authors: Fan Sisi , Zhou Siqi , Ma Jun , An Wenhong , Wang Honghong , Xiao Tao
Published: March 2024

Background

The retention of new nurses has become a major challenge for medical institutions. Job embeddedness has been seen as a valuable lens for examining nurse turnover, but greater details about job embeddedness are rarely disclosed, especially among new nurses. This study aimed to reveal how the nursing work environment, head nurse leadership and presenteeism shape job embeddedness in this population from the perspective of conservation of resources (COR) theory.

Method

A cross-sectional multicentre study involving 436 participants from 10 cities and 33 hospitals was conducted over 4 months. Samples were selected using a two-stage convenience sampling method. A sequential multiple mediation model performed with SPSS-PROCESS was used to analyse the relationships among the nursing work environment, head nurse leadership, presenteeism and job embeddedness.

Results

The nursing work environment not only directly affects the job embeddedness of new nurses (β = 0.480, p < 0.001) but also indirectly affects it through the sequential multiple mediating effects of head nurse leadership and presenteeism (R2 = 0.535, F = 82.160, p < 0.001).

Conclusions

New nurses’ job embeddedness needs to be improved. These results suggest that preserving adequate resources for new nurses, such as work environment resources, head nurse leadership resources, and individual productivity resources, is an effective way to shape their job embeddedness. In addition, when a certain resource is insufficient, fully considering the principles of investment and buffering between resources and providing reciprocal, alternative, or buffer resources in a timely manner are necessary to improve new nurses’ job embeddedness.
