ABSTRACT

Ambulatory sleep and blood pressure monitoring are gaining popularity as these can be completed in an individual’s home. Little is known regarding the reliability of data and the time it takes to acclimate to the equipment. This study aimed to determine how many nights of wearing the monitoring equipment were required to restore sleep architecture and blood pressure data to baseline. It was hypothesized familiarization would be demonstrated by night 3. Ten male and 10 female subjects completed three nights of sleep and blood pressure recordings. At visit 1, the subjects were familiarized with the equipment and instructed to wear the Sleep Profiler{trade mark, serif} and SunTech Medical Oscar2 ambulatory blood pressure cuff simultaneously for three consecutive nights, then subjects returned the equipment. The percent of time spent in rapid eye-movement (REM) sleep was statistically different on night 3 when compared to night 1. Wake-after-sleep onset and sleep latency were not statistically different between nights 1, 2, and 3. Systolic, diastolic, and pulse pressure were all significantly lower on night 3 compared to night 1. Cortical and autonomic arousals were statistically different on night 3. Ambulatory sleep and blood pressure monitoring need at least 3 nights for familiarization. The percent of time spent in REM sleep was statistically different on night 3 when compared to night 1. Systolic blood pressure, diastolic blood pressure, and pulse pressure were all significantly lower on night 3 compared to night 1. Cortical and autonomic arousals were statistically different on nights 3 and 2, respectively compared to night 1. Based on these findings, ambulatory sleep and blood pressure monitoring takes three nights before the data are reliable and the person is familiarized with the mode of measurement. Therefore, it is recommended to use at least three nights of data collection when using the Sleep Profiler and Oscar2 ambulatory blood pressure cuff in order for results to be valid and reliable.

ABSTRACT

PURPOSE: The purpose of this study was to characterize the impact of detraining due to the COVID-19 pandemic on incidence of bony injuries and stress fractures in collegiate athletes.

METHODS: A comprehensive collegiate athletic conference injury database was queried for all in-season, sport-related bony injuries (defined as all stress reactions and fractures) that occurred across all sports from January 2016 to June 2021. The bony injury rate per 1000 athlete exposure hours (AEH) was calculated and compared between the immediate post-hiatus season and historic rates from pre-hiatus seasons (2016-2019). Injury characteristics were also compared between the pre- and post-hiatus time periods.

RESULTS: A total of 868 bony injuries across 23 sports were identified. The sports with highest overall baseline bony injury rates in historic seasons were women’s cross country (0.57 injuries per 1000 AEH) and men’s cross country (0.32). Compared to historic pre-hiatus rates, female cross-country runners demonstrated a significantly lower bony injury incidence rate in the post-hiatus season (0.24 vs. 0.57, p = 0.016) while male swimming athletes demonstrated a statistically significant increase in bony injury rate (0.09 vs. 0.01, p = 0.015). The proportion of bony injuries attributed to repetitive trauma increased; while, the proportion of injuries attributed to running decreased between the pre- and post-hiatus seasons.

CONCLUSION: Across all sports, there was no consistent trend toward increased rates of bony injury in the immediate post-hiatus season. However, female cross-country runners demonstrated lower rates of bony injury in the post-hiatus season while male swimmers demonstrated higher rates. Furthermore, bony injuries in the post-hiatus season were more likely to be the result of repetitive trauma and less likely to be from running.

LEVEL OF EVIDENCE: Level III, retrospective, cross sectional study.

ABSTRACT

BACKGROUND: Dietary patterns that include high-quality and varied food groups have the potential to modulate oxidative status. This research was conducted to determine dietary diversity score (DDS) and food quality score (FQS) in football players and their matched non-athletes, also their associations with oxidative indicators assessed by the urinary levels of F_2alpha-isoprostane (F_2a-IP) and 8-hydroxy-2′-deoxyguanosine (8-OHdG).

METHODS: Participants consisted of 45 male football players and 45 male non-athletes in two age-and body mass index (BMI)-matched groups from Shiraz City, Iran. Anthropometric measurements were performed, and urine samples were analyzed to determine oxidative biomarkers. Dietary data derived from a reliable food frequency questionnaire with 168 items was completed to determine DDS and FQS. For data analysis, an appropriate generalized estimating equation model was set up.

RESULTS: Our results demonstrated that FQS (β = 5.46; P < 0.001) and DDS (β = 1.30; P < 0.001) scores were significantly higher in the footballers in comparison to the non-athletes. Moreover, FQS was negatively associated with 8-OHdG (β=-0.35; P = 0.008) and F_2a-IP (β=-4.30; P = 0.01) levels in all participants. In addition, DDS was inversely related to 8-OHdG (β=-1.25; P = 0.01) and F_2a-IP (β=-11.67; P = 0.04) levels in all participants.

CONCLUSIONS: Food quality scores and dietary diversity of footballers’ diets were found to be higher in comparison to the non-athletes. Furthermore, a higher FQS and DDS were associated with lower levels of oxidative biomarkers in all participants.

ABSTRACT

BACKGROUND: The importation of parasites across borders remains a threat to malaria elimination. The Southern African Development Community Malaria Elimination Eight (E8) established 39 border health facilities on 5 key international borders between high and low-burden countries. These clinics aimed to improve access to prevention, diagnosis, and treatment of malaria for residents in border areas and for mobile and migrant populations who frequently cross borders. Studies were conducted in each of the four high-burden E8 countries (Angola, Mozambique, Zambia, and Zimbabwe) to evaluate malaria services in border areas.

METHODS: Cross-sectional surveys were conducted within 30 km of recently established E8 Border Health Posts. Structured questionnaires were administered to randomly selected respondents to assess malaria-related knowledge and behavior, access to malaria prevention, diagnosis and treatment of malaria, and risk factors for malaria associated with local and cross-border travel.

RESULTS: Results showed that most providers followed appropriate guidelines performing blood tests when individuals presented with fever, and that nearly all those who reported a positive blood test received medication. Lack of access to health care due to distance, cost or mistrust of the provider was rare. A minority of respondents reported not receiving timely diagnosis either because they did not seek help, or because they were not offered a blood test when presenting with fever. There was a high level of correct knowledge of causes, symptoms, and prevention of malaria. A majority, of border residents had access to primary prevention against malaria through either long-lasting insecticidal nets (LLINs) or indoor residual spraying (IRS). Cross border travel was common with travellers reporting sleeping outside without protection against malaria.

CONCLUSIONS: The study demonstrated the importance of border health facilities in providing access to malaria services. Prevention needs to be improved for people who travel and sleep outdoors. Community health workers can play a key role in providing access to information, testing and treating malaria.

ABSTRACT

BACKGROUND: Basic Life Support (BLS) plays an important role in increasing the survival rate of hospitalized heart attack patients. There are no previous studies on the effect of BLS training among Palestinian nurses. This study aimed to evaluate the effect of simulation-based BLS training program on nurses’ knowledge Palestinian nurses at governmental hospitals.

METHODS: A quasi-experimental, pre & post-test design was used. 700 nurses were recruited proportionally using a simple random sampling method among 2980 nurses from 13 public hospitals in the Gaza Strip. This study was conducted from June to August 2022. A practical BLS test consisting of 10 multiple-choice questions according to American Heart Association guidelines (2020) was collected and sociodemographic characteristics. SPSS software, version 24 was used for the statistical analysis. Descriptive statistics and weighted mean were used. T-Test and One-way analysis of variance (ANOVA) were applied to determine differences in means among groups.

RESULTS: Most of the participating nurses (55.7%) were male, while (44.3%) were female. The majority of nurses (84.4%) are under 40 years of age. The weighted mean scores in the pre-test ranged from 52.2 to 75.1% and the mean scores was (6.16 ± 1.97). After applying conventional BLS training, the weighted mean scores ranged from 85.6 to 97.3% and the mean scores was (9.19 ± 1.04). The study revealed that the nurses’ knowledge increased after applying simulation-based training program. The mean of knowledge scores was statistically significant between the pre and post-test on the basis of the current work hospital (P-value < 0.001).

CONCLUSION: This study affords significant evidence of the positive effects of the BLS training program in improving nurses’ knowledge; we recommend advanced BLS training for all healthcare providers, doctors, and nurses working in hospitals and healthcare centers. Nursing managers can implement systematic strategies to enhance nurses’ knowledge and practice in BLS to target low-scoring Governorates.

ABSTRACT

BACKGROUND: Intimate partner violence (IPV) remains a global public health concern for both men and women. Spatial mapping and clustering analysis can reveal subtle patterns in IPV occurrences but are yet to be explored in Rwanda, especially at a lower small-area scale. This study seeks to examine the spatial distribution, patterns, and associated factors of IPV among men and women in Rwanda.

METHODS: This was a secondary data analysis of the 2019/2020 Rwanda Demographic and Health Survey (RDHS) individual-level data set for 1947 women aged 15-49 years and 1371 men aged 15-59 years. A spatially structured additive logistic regression model was used to assess risk factors for IPV while adjusting for spatial effects. The district-level spatial model was adjusted for fixed covariate effects and was implemented using a fully Bayesian inference within the generalized additive mixed effects framework.

RESULTS: IPV prevalence amongst women was 45.9% (95% Confidence interval (CI): 43.4-48.5%) while that for men was 18.4% (95% CI: 16.2-20.9%). Using a bivariate choropleth, IPV perpetrated against women was higher in the North-Western districts of Rwanda whereas for men it was shown to be more prevalent in the Southern districts. A few districts presented high IPV for both men and women. The spatial structured additive logistic model revealed higher odds for IPV against women mainly in the North-western districts and the spatial effects were dominated by spatially structured effects contributing 64%. Higher odds of IPV were observed for men in the Southern districts of Rwanda and spatial effects were dominated by district heterogeneity accounting for 62%. There were no statistically significant district clusters for IPV in both men or women. Women with partners who consume alcohol, and with controlling partners were at significantly higher odds of IPV while those in rich households and making financial decisions together with partners were at lower odds of experiencing IPV.

CONCLUSION: Campaigns against IPV should be strengthened, especially in the North-Western and Southern parts of Rwanda. In addition, the promotion of girl-child education and empowerment of women can potentially reduce IPV against women and girls. Furthermore, couples should be trained on making financial decisions together. In conclusion, the implementation of policies and interventions that discourage alcohol consumption and control behaviour, especially among men, should be rolled out.

ABSTRACT

AIM: Although the efficacy and safety of mesenchymal stem cell therapy for liver cirrhosis have been demonstrated in several studies. Clinical cases of mesenchymal stem cell therapy for patients with liver cirrhosis are limited and these studies lack the consistency of treatment effects. This article aimed to systematically investigate the efficacy and safety of mesenchymal stem cells in the treatment of liver cirrhosis.

METHOD: The data source included PubMed/Medline, Web of Science, EMBASE, and Cochrane Library, from inception to May 2023. Literature was screened by the PICOS principle, followed by literature quality evaluation to assess the risk of bias. Finally, the data from each study’s outcome indicators were extracted for a combined analysis. Outcome indicators of the assessment included liver functions and adverse events. Statistical analysis was performed using Review Manager 5.4.

RESULTS: A total of 11 clinical trials met the selection criteria. The pooled analysis’ findings demonstrated that both primary and secondary indicators had improved. Compared to the control group, infusion of mesenchymal stem cells significantly increased ALB levels in 2 weeks, 1 month, 3 months, and 6 months, and significantly decreased MELD score in 1 month, 2 months, and 6 months, according to a subgroup analysis using a random-effects model. Additionally, the hepatic arterial injection favored improvements in MELD score and ALB levels. Importantly, none of the included studies indicated any severe adverse effects.

CONCLUSION: The results showed that mesenchymal stem cell was effective and safe in the treatment of liver cirrhosis, improving liver function (such as a decrease in MELD score and an increase in ALB levels) in patients with liver cirrhosis and exerting protective effects on complications of liver cirrhosis and the incidence of hepatocellular carcinoma. Although the results of the subgroup analysis were informative for the selection of mesenchymal stem cells for clinical treatment, a large number of high-quality randomized controlled trials validations are still needed.

ABSTRACT

Diversity-generating and mobile genetic elements are key to microbial and viral evolution and can result in evolutionary leaps. State-of-the-art algorithms to detect these elements have limitations. Here, we introduce DIVE, a new reference-free approach to overcome these limitations using information contained in sequencing reads alone. We show that DIVE has improved detection power compared to existing reference-based methods using simulations and real data. We use DIVE to rediscover and characterize the activity of known and novel elements and generate new biological hypotheses about the mobilome. Building on DIVE, we develop a reference-free framework capable of de novo discovery of mobile genetic elements.

ABSTRACT

BACKGROUND: This study aims to illustrate the impact of applying the tranexamic acid impregnated in a gelatin sponge between the anterior rectus sheath and the Rectus Abdominis muscle during Cesarean section (CS) in minimizing rectus sheath hematoma (RHS) in women treated with Warfarin.

METHODS: A clinical trial was carried out on 63 pregnant women attended for elective CS, who on antenatal warfarin anticoagulation started from 13 weeks gestation to 36 weeks then shifted to low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH), and with an indication for postnatal warfarin anticoagulation. They were randomly assigned on the day of the scheduled CS into three equal groups (21 women for each). Group 1 had two pieces of gelatin sponges soaked with one ampoule of tranexamic acid. Group 2 had two pieces of gelatin sponges not soaked with tranexamic acid. Group 3 (control group) had no gelatin sponge applied. All patients underwent postoperative assessment done for hemoglobin (Hb), hematocrit (HCT), estimated blood loss (EBL), amount and nature of discharge collected from the sub-rectus drain, complications (RHS, wound infection, thromboembolism), need for re-operation, and need for blood transfusion.

RESULTS: Statistically significant differences were found between Group 1 and Group 2 regarding the postoperative Hb (10.66 ± 1.13 vs. 9.77 ± 0.69, P = 0.009), between Group 1 and Group 2 regarding the postoperative HCT (31.87 ± 3.59 vs. 28.54 ± 1.85, P = 0.001), between Group 1 and Group 2 regarding EBL (442.19 ± 244.46 vs. 744.38 ± 267.05, P = 0.003), between Group 1 and Group 3 regarding EBL (442.19 ± 244.46 vs. 664.29 ± 343.97, P = 0.040), and between Group 1 and Group 3 regarding the discharge amount from the sub rectus drain (190.48 ± 100.77 vs. 307.14 ± 127.76, P = 0.004).

CONCLUSION: Tranexamic acid-soaked gelatin sponges are safe and effective in reducing postoperative drainage and EBL.

CLINICAL TRIAL REGISTRATION: At ClinicalTrials.gov in June 2022 (NCT05439694).

ABSTRACT

BACKGROUND: Research on the long-term effects of COVID-19 infection is ongoing, and the psychological and physical impacts of Long Covid on youth is poorly understood. To assess these impacts, we surveyed youth regarding their experiences with, and perspectives on, the long-term effects of COVID-19.

METHODS: We conducted a nationwide text message survey of youth ages 14-24 years in the United States. The survey asked four open ended questions regarding their experiences and perceptions regarding the long-term effects of COVID-19. Qualitative data was analyzed independently by three investigators using thematic analysis. Prevalence of codes were summarized using descriptive statistics.

RESULTS: Among 1150 participants, 991 responded to at least one survey question (response rate 86.1%). The vast majority of our sample had COVID-19 or knew someone who did (75%), and approximately one third (32%) of youth indicated that they knew someone who had experienced symptoms consistent with Long Covid. Many youth (50%) reported worry and concern about Long Covid even if they, or someone they knew, did not have Long Covid. Among youth who were not concerned about Long Covid, the most commonly reported reasons were having received the vaccine (29%) and not having a prior COVID-19 infection (24%).

CONCLUSIONS: Our findings suggest that among younger populations, there is significant concern regarding the long-term effects of COVID-19. Vaccination campaigns and youth-centered public health communication about Long Covid may not only reduce COVID-19 transmission, but also alleviate worries and concerns about Long Covid among youth.
