ABSTRACT

BACKGROUND AND AIM: With the worldwide outbreak of coronavirus, a significant impact has been observed on the functioning of healthcare systems and the process of childbirth. Women probably did not even have a choice to adjust their plans accordingly to the current situation. The aim of the study was to examine how the outbreak of the SARS CoV-2 pandemic state affected the decisions of pregnant women about their childbirth plan.

DESIGN: This cross-sectional study was performed using a web-based survey published on social media in Poland.

METHODS: The cross-sectional study was performed using web-based questionnaires. The study group included Polish women who changed their childbirth plans, compared to a group of women not sure about delivery plan change and those whose plans had not changed. The data were collected from 4 March 2020 to 2 May 2020, when the first rising count of new infections was observed in Poland and worldwide. Statistical analysis was performed using STATISTICA Software, Inc., 13.3 (2020).

RESULTS: Of 969 women who completed the questionnaire and were enrolled into the study, 57.2% had not changed their childbirth plans (group I), 28.4% had changed their plans (group II), and 14.4% of respondents answered “not sure” to this question (group III). The majority of women changed their birth plans during the pandemic because of the potential absence of their partner during labour (56% of women who had changed their plans and 48% of those whose answer was “I am not sure”, p < .001). Another reason was the fear of separation from the child after delivery (33% of women who had changed their plans and 30% of those whose answer was “I am not sure”, p < .001).

CONCLUSION: Restrictions due to the COVID-19 outbreak have influenced the childbirth plans of pregnant women. The changes were independent of women’s vision of birth before the pandemic.

IMPACT: The restriction on births with accompanying person and the risk of separation from their infant after childbirth significantly influenced the decision-making process. As a result, some women were more likely to opt for a home birth with or even without medical assistance.

PATIENT OR PUBLIC CONTRIBUTION: The study participants were women who were pregnant at the time of completing the questionnaire, were over 18 years old and spoke Polish.

ABSTRACT

BACKGROUND: From 6 months of age, children need, in addition to breast milk, a complementary food whose nutritional composition meets their needs. However, low consumption of child-specific foods in favor of adult foods has been documented. Thus, the lack of adaptation of children to family feeding conditions has been the source of frequent malnutrition in some low-income countries. In Burkina Faso, little data is available on family-type food consumption by children. The objective was to describe the socio-cultural influences on feeding habits and food consumption frequencies of infants aged 6-23 months in Ouagadougou.

METHODS: The study was conducted from March to June 2022 using a structured questionnaire. A reminder of the previous 24 h’ meals was used to assess 618 children’s food consumption. Mother-child pairs were selected using the simple random sampling method, and data collection was done by the interview method. Sphinx V5, IBM SPSS Statistics 20.0 and XLSTAT 2016 software were used to process data.

RESULTS: Influences between the consumption of certain foods and the mother’s social status were observed. The most consumed foods are simple porridges (67.48%), Tô/rice (65.70%), cookies and cakes (62.94%), juices and sweetened drinks (62.94%). Cowpeas (17.31%), improved porridge (13.92%) and eggs (6.63%) are the least consumed. The most meals frequency was three meals daily (33.98%), and children with the minimum daily meal frequency were 86.41%. Principal component analysis showed that the mother’s social status influenced the consumption of imported infant flours, fish soups, fruits, juices and sweetened drinks, cookies and cakes, simple porridge, and tô/rice. Concerning the consumption of local infant porridges, 55.72% of the children who consumed them appreciated positively. However, for 57.75% of the parents, the lack of information limits the consumption rate of this type of flour.

CONCLUSION: High consumption of family-type meals was observed and was influenced by parental social status. In addition, the rate of acceptable meal frequencies was generally high.

ABSTRACT

OBJECTIVES: To examine the occurrence of magnetic resonance imaging (MRI) changes in the thoracolumbar spine among elite climbing athletes.

METHODS: All climbers of the Swedish national sport climbing team (n = 8), and individuals having trained for selection to the national team (n = 11), were prospectively included. A control group, matched in age and sex, were recruited. All participants underwent a thoracolumbar MRI (1.5 T, T1- and T2-weighted imaging), evaluated according to Pfirrmann classification, modified Endplate defect score, Modic changes, apophyseal injuries and spondylolisthesis. Pfirrmann ≥ 3, Endplate defect score ≥ 2 and Modic ≥ 1 was defined as degenerative findings.

RESULTS: Fifteen individuals, 8 women, participated in both the climbing group (mean age 23.1, SD 3.2 years) and the control group respectively (mean age 24.3, SD 1.5 years). In the climbing group, 6.1% of the thoracic and 10.6% of the lumbar intervertebral discs showed signs of degeneration according to Pfirrmann. One disc with a grade above 3 was present. Modic changes in the thoracic/lumbar spine were prevalent in 1.7%/1.3% of the vertebrae. Degenerative endplate changes according to the Endplate defect score were found in 8.9% and 6.6% of the thoracic and lumbar spinal segments of the climbing group, respectively. Two apophyseal injuries were found, while no participants displayed signs of spondylolisthesis. There was no difference in point-prevalence of radiographic spinal changes between climbers and controls (0.07 < p < 1.0).

CONCLUSION: In this small cross-sectional study, only a low proportion of elite climbers displayed changes of the spinal endplates or intervertebral discs, as opposed to other sports with high spinal loads. Most observed abnormalities were low grade degenerative changes and did not differ statistically compared to controls.

ABSTRACT

OBJECTIVE: To assess in retrospect the effects of brachial plexus block and general anesthesia on children with lateral humeral condyle fractures in terms of postoperative pain and return of upper limb function.

METHODS: Randomly allocated to either the control group (n = 51) or the study group (n = 55) were children with lateral humeral condyle fractures who were admitted to our hospital between October 2020 and October 2021, depending on the surgical anesthetic technique used. The research group had internal fixation surgery with brachial plexus block in addition to anesthesia on the basis of the control group, whereas both groups of children underwent the procedure with general anesthesia alone. Postoperative pain degree, upper extremity functional recovery, occurrence of adverse reactions, etc. RESULTS: The study group had shorter mean times for surgery, anesthesia, propofol dose, return to consciousness, and extubation than the control group did at every measure of statistical significance. The T2 heart rate (HR) and mean arterial pressure (MAP) were both significantly lower than the pre-anesthesia HR and MAP, and the T1, T2, and T3 HR and MAP were all significantly lower in the study group compared to the control group (P < 0.05). The difference between the SpO2 values at T0 and T3 was not statistically significant (P > 0.05); the VAS scores at 4 h, 12 h, and 48 h after surgery were higher than those at 2 h after surgery, and reached the peak at 4 h after surgery; within 2 h, 4 h, and 12 h of surgery At 48 h, the study group had substantially lower VAS ratings than the control group (P < 0.05). Post-treatment Fugl-Meyer scale scores were considerably higher across the board compared to pre-treatment levels in both groups. When compared to the control group, individuals who participated in the flexion-stretching coordinated exercise and the separation exercise had significantly better ratings. Electrocardiogram, blood pressure, respiratory circulation, and hemodynamic parameters all remained within normal limits during the surgical procedure. The study group had a 9.09% reduced incidence of adverse events compared to the control group. 19.61% (P < 0.05).

CONCLUSION: When used in conjunction with general anesthesia, brachial plexus block can help children with lateral humeral condyle fractures regulate perioperative signs, maintain their hemodynamic level, lessen postoperative pain and unpleasant reactions, and improve the function of their upper limbs. Functional recovery, with high safety and effectiveness.

ABSTRACT

BACKGROUND: Non-pharmaceutical interventions (NPIs) have been implemented worldwide to suppress the spread of coronavirus disease 2019 (COVID-19). However, few studies have evaluated the effect of NPIs on other infectious diseases and none has assessed the avoided disease burden associated with NPIs. We aimed to assess the effect of NPIs on the incidence of infectious diseases during the COVID-19 pandemic in 2020 and evaluate the health economic benefits related to the reduction in the incidence of infectious diseases.

METHODS: Data on 10 notifiable infectious diseases across China during 2010-2020 were extracted from the China Information System for Disease Control and Prevention. A two-stage controlled interrupted time-series design with a quasi-Poisson regression model was used to examine the impact of NPIs on the incidence of infectious diseases. The analysis was first performed at the provincial-level administrative divisions (PLADs) level in China, then the PLAD-specific estimates were pooled using a random-effect meta-analysis.

RESULTS: A total of 61,393,737 cases of 10 infectious diseases were identified. The implementation of NPIs was associated with 5.13 million (95% confidence interval [CI] 3.45‒7.42) avoided cases and USD 1.77 billion (95% CI 1.18‒2.57) avoided hospital expenditures in 2020. There were 4.52 million (95% CI 3.00‒6.63) avoided cases for children and adolescents, corresponding to 88.2% of total avoided cases. The top leading cause of avoided burden attributable to NPIs was influenza [avoided percentage (AP): 89.3%; 95% CI 84.5‒92.6]. Socioeconomic status and population density were effect modifiers.

CONCLUSIONS: NPIs for COVID-19 could effectively control the prevalence of infectious diseases, with patterns of risk varying by socioeconomic status. These findings have important implications for informing targeted strategies to prevent infectious diseases.

ABSTRACT

AIM: To design a protocol based on the experiences of long-term survivors to facilitate resilience for oesophageal cancer patients in rural China.

BACKGROUND: According to the latest Global Cancer Statistics Report, 604,000 new cases of oesophageal cancer were reported, of which over 60% of the disease burden is distributed in China. The incidence of oesophageal cancer in rural China (15.95/100,000) is twice as high as those in urban areas (7.59/100,000). To be sure, resilience can help patients better adapt to post-cancer life. But universal interventions involving improving the resilience of oesophageal cancer patients have much less been explored, especially for rural patients.

METHODS: The two-arm, parallel design, non-blinded, randomised controlled trial will be implemented in 86 adults diagnosed with oesophageal cancer and will be randomly assigned to the control group or the intervention group via the blocked randomisation. The intervention group will undergo an intervention with one-on-one guidance from a nurse while viewing a CD of the experiences of long-term survivors with oesophageal cancer in rural areas. Every 2 weeks, a theme session will be introduced, and the entire intervention will continue for 12 weeks. Psychosocial variables (resilience, self-efficacy, coping mode and family support) will be surveyed at baseline, post-intervention and 3 months after the intervention. The paper complies with the Standard Protocol Items: Recommendations for Intervention Trials 2013 and Consolidated Standards of Reporting Trials guidelines for study protocols adapted for designing and reporting parallel group randomised trials.

CONCLUSION: The intervention programme transitions from hospitalisation to discharge, which includes one-on-one interventions by medical personnel and a portable CD describing the experiences of long-term survivors with rural oesophageal cancer. Once the intervention’s effectiveness is proven, this protocol will provide psychological support for massive oesophageal cancer patients.

RELEVANCE TO CLINICAL PRACTICE: The intervention programme may be used as an auxiliary therapy to promote patients’ postoperative psychological rehabilitation. This programme has the advantages of being cost-effective, flexible, accessible, and convenient and can be implemented without the limitation of time, place and clinical medical staff.

ABSTRACT

BACKGROUND: Eating alone has been significantly associated with psychological distress. However, there is no research that evaluates the effects or relation of eating together online to autonomic nervous system functions.

METHODS: This is a randomized, open-label, controlled, pilot study conducted among healthy volunteers. Participants were randomized into either an eating together online group or an eating-alone group. The effect of eating together on autonomic nervous functions was evaluated and compared with that of the control (eating alone). The primary endpoint was the change in the standard deviation of the normal-to-normal interval (SDNN) scores among heart rate variabilities (HRV) before and after eating. Physiological synchrony was investigated based on changes in the SDNN scores.

RESULTS: A total of 31 women and 25 men (mean age, 36.6 [SD = 9.9] years) were included in the study. In the comparison between the aforementioned groups, two-way analysis of variance revealed interactions between time and group on SDNN scores. SDNN scores in the eating together online group increased in the first and second halves of eating time (F[1,216], P < 0.001 and F[1,216], P = 0.022). Moreover, high correlations were observed in the changes in each pair before and during the first half of eating time as well as before and during the second half of eating time (r = 0.642, P = 0.013 and r = 0.579, P = 0.030). These were statistically significantly higher than those in the eating-alone group (P = 0.005 and P = 0.040).

CONCLUSIONS: The experience of eating together online increased HRV during eating. Variations in pairs were correlated and may have induced physiological synchrony.

ABSTRACT

BACKGROUND: Trauma is the leading cause of morbidity and mortality among adult population in the world. Despite many improvements in technology and care, mortality among trauma patients in the intensive care unit is still high particularly in Ethiopia. However, there is limited evidence on the incidence and predictors of mortality among trauma patients in Ethiopia. Therefore, this study aimed to assess the incidence and predictors of mortality among adult trauma patients admitted to intensive care units.

METHODS: Institutional-based retrospective follow-up study was conducted from January 9, 2019 to January 8, 2022. A total of 421 samples were chosen using simple random sampling. Data were collected with Kobo toolbox software and exported to STATA version 14.1 software for data analysis. Kaplan-Meier failure curve and log-rank test were fitted to explore the survival difference among groups. After the bivariable and multivariable Cox regression analysis, an Adjusted Hazard Ratio (AHR) with 95% Confidence Intervals (CI) was reported to declare the strength of association and statistical significance, respectively.

RESULT: The overall incidence rate of mortality was 5.47 per 100 person-day observation with a median survival time of 14 days. Did not get pre-hospital care (AHR = 2.00, 95%CI 1.13, 3.53), Glasgow Coma Scale (GCS) score < 9 (AHR = 3.89, 95%CI 1.67, 9.06), presence of complications (AHR = 3.71, 95%CI 1.29, 10.64), hypothermia at admission (AHR = 2.11, 95%CI 1.13, 3.93) and hypotension at admission (AHR = 1.93, 95%CI 1.01, 3.66) were found significant predictors of mortality among trauma patients.

CONCLUSION: The incidence rate of mortality among trauma patients in the ICU was high. Did not get pre-hospital care, GCS < 9, presence of complications, hypothermia, and hypotension at admission were significant predictors of mortality. Therefore, healthcare providers should give special attention to trauma patients with low GCS scores, complications, hypotension, and hypothermia and better to strengthen pre-hospital services to reduce the incidence of mortality.

ABSTRACT

BACKGROUND: The loss in age-related immunological markers, known as immunosenescence, is caused by a combination of factors, one of which is inflammaging. Inflammaging is associated with the continuous basal generation of proinflammatory cytokines. Studies have demonstrated that inflammaging reduces the effectiveness of vaccines. Strategies aimed at modifying baseline inflammation are being developed to improve vaccination responses in older adults. Dendritic cells have attracted attention as an age-specific target because of their significance in immunization as antigen presenting cells that stimulate T lymphocytes.

RESULTS: In this study, bone marrow derived dendritic cells (BMDCs) were generated from aged mice and used to investigate the effects of combinations of adjuvants, including Toll-like receptor, NOD2, and STING agonists with polyanhydride nanoparticles and pentablock copolymer micelles under in vitro conditions. Cellular stimulation was characterized via expression of costimulatory molecules, T cell-activating cytokines, proinflammatory cytokines, and chemokines. Our results indicate that multiple TLR agonists substantially increase costimulatory molecule expression and cytokines associated with T cell activation and inflammation in culture. In contrast, NOD2 and STING agonists had only a moderate effect on BMDC activation, while nanoparticles and micelles had no effect by themselves. However, when nanoparticles and micelles were combined with a TLR9 agonist, a reduction in the production of proinflammatory cytokines was observed while maintaining increased production of T cell activating cytokines and enhancing cell surface marker expression. Additionally, combining nanoparticles and micelles with a STING agonist resulted in a synergistic impact on the upregulation of costimulatory molecules and an increase in cytokine secretion from BMDCs linked with T cell activation without excessive secretion of proinflammatory cytokines.

CONCLUSIONS: These studies provide new insights into rational adjuvant selection for vaccines for older adults. Combining appropriate adjuvants with nanoparticles and micelles may lead to balanced immune activation characterized by low inflammation, setting the stage for designing next generation vaccines that can induce mucosal immunity in older adults.

ABSTRACT

BACKGROUND: Emerging evidence suggests that DNA methylation can be affected by physical activities and is associated with cardiac fibrosis. This translational research examined the implications of DNA methylation associated with the high-intensity interval training (HIIT) effects on cardiac fibrosis in patients with heart failure (HF).

METHODS: Twelve HF patients were included and received cardiovascular magnetic resonance imaging with late gadolinium enhancement for cardiac fibrosis severity and a cardiopulmonary exercise test for peak oxygen consumption ([Formula: see text]O_2peak). Afterwards, they underwent 36 sessions of HIIT at alternating 80% and 40% of [Formula: see text]O_2peak for 30 min per session in 3-4 months. Human serum from 11 participants, as a means to link cell biology to clinical presentations, was used to investigate the exercise effects on cardiac fibrosis. Primary human cardiac fibroblasts (HCFs) were incubated in patient serum, and analyses of cell behaviour, proteomics (n = 6) and DNA methylation profiling (n = 3) were performed. All measurements were conducted after completing HIIT.

RESULTS: A significant increase (p = 0.009) in [Formula: see text]O_2peak (pre- vs. post-HIIT = 19.0 ± 1.1 O₂ ml/kg/min vs. 21.8 ± 1.1 O₂ ml/kg/min) was observed after HIIT. The exercise strategy resulted in a significant decrease in left ventricle (LV) volume by 15% to 40% (p < 0.05) and a significant increase in LV ejection fraction by approximately 30% (p = 0.010). LV myocardial fibrosis significantly decreased from 30.9 ± 1.2% to 27.2 ± 0.8% (p = 0.013) and from 33.4 ± 1.6% to 30.1 ± 1.6% (p = 0.021) in the middle and apical LV myocardium after HIIT, respectively. The mean single-cell migration speed was significantly (p = 0.044) greater for HCFs treated with patient serum before (2.15 ± 0.17 μm/min) than after (1.11 ± 0.12 μm/min) HIIT. Forty-three of 1222 identified proteins were significantly involved in HIIT-induced altered HCF activities. There was significant (p = 0.044) hypermethylation of the acyl-CoA dehydrogenase very long chain (ACADVL) gene with a 4.474-fold increase after HIIT, which could activate downstream caspase-mediated actin disassembly and the cell death pathway.

CONCLUSIONS: Human investigation has shown that HIIT is associated with reduced cardiac fibrosis in HF patients. Hypermethylation of ACADVL after HIIT may contribute to impeding HCF activities. This exercise-associated epigenetic reprogramming may contribute to reduce cardiac fibrosis and promote cardiorespiratory fitness in HF patients.
