ABSTRACT

INTRODUCTION: Psychological distress had been documented since the beginning of the COVID-19 outbreak in 2019. The aim of the study is to describe the psychological impact among those who were hospitalized for COVID-19 infection within 6 months after being discharged from the hospital. The psychological impact in this study is defined as depression, anxiety, and stress.

MATERIALS AND METHODS: This was a cross-sectional study conducted from July 2020 till August 2021 in a regional state hospital, north of Malaysia. All patients requiring hospitalization for COVID-19 were approached within the first 2 weeks after admission to administer the Depression, Anxiety and Stress Scale – 21 Items (DASS-21) scale. Follow-up phone calls were made within 3 months of discharged to enquire about the DASS-21 items as well as the Impact of Event Scale-Revised (IES-R) scale items. Participants above the age of 18 and technology savvy to answer an online questionnaire were recruited for the study. We excluded participants with a known history of psychotic disorder from the study. We utilised the DASS-21 to screen for depression, anxiety, and stress, as well as the IES-R to identify symptoms of post-traumatic stress disorder. Participants could answer the questionnaires in either English or Bahasa Malaysia. For comparison of two categorical data, a chi-square was applied. A univariate analysis was first conducted and all variables with a p ≤0.3 was then entered into the multivariate analysis for the final output. Other than the univariate analysis, all other p values <0.05 were considered to be statistically significant. All data collected were tabulated and analysed in the SPSS v21.0 system.

RESULTS: A total of 306 out of 696 COVID-19 patients responded. The mean age for the participants was 31.69 (SD:11.19) years old. From the total, 54.2% were ladies, 78.8% were Malay, 50.7% were unmarried, 55.2% had higher education, and 67.6% were employed at the time of the survey. We found 20.5% of the participants were depressed, 38.9% had moderate anxiety, and 17.3% were stressed. From the total, 31.7% of the participants were deemed to have had some symptoms of post-traumatic stress disorder (PTSD) ranging from mild to severe. From the final multivariate analysis, it was found that depression (p=0.02) had a 2.78 times likeliness of having PTSD, anxiety (p<0.001) had a 3.35 times likeliness of having PTSD and stressed patients (p=0.02) 2.86 times likeliness of having PTSD when compared to those without PTSD.

CONCLUSION: Patients reported to suffer from symptoms of PTSD and might benefit from psychological interventions to mitigate the impact in the long run.

ABSTRACT

OBJECTIVES: Angiogenesis is engaged in endometriosis. It is regulated by regulatory factors and cytokines, transported in microvesicles. The purpose was to investigate the presence of MVs with vascular endothelial growth factor (VEGF) and metalloproteinase-9 (MMP-9) in peripheral blood and peritoneal fluid of women operated on for endometrioma or teratoma Material and methods:Microvesicles (MVs) were determined in blood samples and peritoneal fluid samples collected from women aged 20-60 years operated on for endometriosis (test group) and teratoma (control group). The final investigations were performed on 47 patients, who qualified for the study based on the meticulous inclusion criteria. MVs were analyzed by flow cytometry (FACS) using annexin V, antibodies for molecules characteristic of cells from endometriosis foci (keratin 18 (K18), CD105, CD146), and antibodies for intraepithelial vascular growth factor VEGF and metalloproteinase-9 (MMP-9). The sample was double “reading” using flow cytometry (FACSCantoII).

RESULTS: Cytometry analysis confirmed MVs’ presence in plasma and peritoneal fluid collected from patients with both endometriosis and teratomas. A statistically significant higher level of AnnexinV (+) MVs were observed in plasma samples of endometriosis patients. In the control group, there was a higher percentage of double-positive VEGF (+)/MMP-9 (+) and single MMP-9 (+) positive MVs in the serum. In the peritoneal fluid higher frequency of double-positive VEGF (+)/MMP-9 (+) MVs were found in the control group. However, the amount of VEGF (+) / MMP-9 (+) MVs object did not enable to differentiate between the test and control groups. The study was the first, in which MVs were confirmed in plasma and peritoneal fluid in benign adnexa tumors.

CONCLUSIONS: Microvesicles are present in peripheral blood and peritoneal fluid samples collected from patients with endometriosis and teratomas. Microvesicles with proangiogenic factors (VEGF and MMP-9) are more abundant in blood and peritoneal fluid samples from patients with teratomas.

ABSTRACT

OBJECTIVES: To explore the application effect of virtual reality (VR) combined with moderate perineal protection on singleton primipara delivery.

MATERIAL AND METHODS: The study utilised a two-group design intervention and a randomised clinical trial. A total of 200 singleton primiparas who had a regular prenatal examination in a third-class hospital (between 1 September 2018 and 30 December 2018) and were willing to give birth naturally were randomly divided into treatment (traditional prenatal health mission combined with desktop VR health education system mode) and control (traditional health education mode) groups. The delivery conditions of the two groups were surveyed, recorded, analysed and compared.

RESULTS: There was no significant difference in the time of the second stage of labour between the treatment and control groups, and the comparison of neonatal Apgar scores and neonatal weight between the two groups showed that the different modes of prenatal education had no effect on newborns (p > 0.05). The amount of postpartum haemorrhage in 2 h and the pain score in the treatment group were significantly lower than in the control group, and the degree of perineal injury in the treatment group was not as serious as that in the control group. Meanwhile, there was a statistically significant difference in the anxiety score, self-efficacy score and quality of life satisfaction between the treatment and control groups (p < 0.05).

CONCLUSIONS: VR technology combined with moderate perineal protection could improve the delivery outcome of a primipara, maternal self-confidence of delivery and the quality of vaginal delivery; effectively alleviate the anxiety of a primipara; have no adverse effects on both mothers and newborns; and be widely used in clinical settings.

ABSTRACT

Characterizing and quantifying the trajectories of variables of interest through time in their field of study is of interest to a range of disciplines. The aim of this study was to investigate the growth speed in height of children and its determinants. A total of 3401 males and 3200 females from four low- and middle-income countries with measured height on five occasions from 2002 to 2016 were included in the study. Data were analyzed using a latent growth model. The results of the study reported that children in four low- and middle-income countries exhibited substantial growth inequalities. There was a significant gender difference in change of growth with males had a higher baseline, rate of change, and acceleration in height growth than females. Comparing the component of slopes across countries, the growth change inequalities were observed among children. These inequalities were statistically significant, with the highest rate of change observed in Peru and Vietnam.

ABSTRACT

PURPOSE: To examine the effect of early mobility (EM) on functional recovery after hip fracture surgery, and to investigate the potential factors that delay mobility.

METHODS: In this retrospective observational study, 110 hip fracture patients were divided into two groups according to the days between surgery and mobility referred to as the EM and the delayed mobility groups. Demographic data, perioperative data, functional outcomes, and discharge destination were compared statistically between the groups using univariate analysis and logistic regression analysis. As a sensitivity analysis, the factors associated with the timing of physiotherapy were also assessed.

RESULTS: The EM group had significantly better walking ability and Barthel index (p < 0.05), and home discharge rate (p = 0.004). The factors associated with delayed mobility (odds ratio; 95% confidence interval) were delayed postoperative physiotherapy initiation (3.59; 1.76-7.33), days from admission to surgery (1.23; 1.04-1.46), and postoperative CRP (1.14; 1.01-1.29) and hemoglobin level (0.72; 0.54-0.96). Furthermore, patients who received surgery on the day before any holiday were significantly delayed in physiotherapy intervention (p = 0.006).

CONCLUSIONS: This study demonstrated that EM after hip fracture surgery was associated with improving functional recovery and home discharge rate, and early physiotherapy intervention was associated with EM.

ABSTRACT

PURPOSE: To compare the effectiveness of two varieties of special needs toothbrushes in terms of dental plaque removal and bacterial contamination vs a conventional toothbrush in patients with Down syndrome.

MATERIALS AND METHODS: This single-blinded, two-group, randomised clinical trial included 16 patients diagnosed with Down syndrome (age 6-15 years) from various special needs centers located in the Jazan Province of Saudi Arabia. The patients were randomly allocated to two groups based on the type of special needs toothbrush provided (Collis Curve or superfine nano). The plaque and bleeding indices of the patients in both groups were measured at baseline (T0) and both groups were initially given a conventional toothbrush to use for four weeks. After this period, the plaque and bleeding indices were re-evaluated (T1). The patients were instructed to use the special needs toothbrush for 4 weeks, after which the periodontal indices were re-evaluated (T2). Microbial contamination on the bristles of the special needs brushes was evaluated at T2.

RESULTS: No notable changes in the mean plaque and bleeding indices were observed between the two groups at each visit; however, statistically significant reductions were noted between visits in both groups (p < 0.05). The CFU scores in cultures from the Collis Curve toothbrush bristles (1411.5 ± 541.1) were higher than those obtained from the superfine nano-toothbrush bristles (1118.3 ± 423.9), but without statistically significant differences.

CONCLUSION: The findings indicate that the use of special needs toothbrushes can statistically significantly improve the gingival health status in individuals with Down syndrome in terms of both resolution of periodontal inflammation and reduction of plaque accumulation.

ABSTRACT

Pressure injuries (PIs) are one of the major and costliest medical problems with severe implications for patients. Cardiovascular surgery patients are at the higher risk of developing surgery-related PIs. So this study was conducted with the aim of investigating the prevalence and factors associated with PIs in patients undergoing open heart surgery. We identified articles through electronic databases such as Web of Science, Scopus, PubMed, ProQuest; and Persian Databases: SID, Magiran and Irandoc without restriction on language or publication period (from inception through June 2022). Finally, 17 studies that fulfilled eligibility criteria were included in final systematic review and meta-analysis. Data analyses were conducted using STATA version 14. The pooled prevalence of PI in patients undergoing open heart surgery was 24.06% (95% CI: 17.85-30.27). High heterogeneity was observed across the included studies (I² = 96.0, P < 0.000). The prevalence by gender was reported as 25.19% (95% CI: 13.45-36.93) in men and 33.36% (95 CI%: 19.99-46.74) in women. The result showed there was statistically significant association between PI and Female sex (Pooled Est: 1.551, 95% CI: 1.199-2.006, z = 3.345, P = 0.001), diabetes (Pooled Est: 1.985, 95% CI: 1.383-2.849, z = 3.719, P = 0.000), advanced age (SMD: 0.33 years; 95% CI: 0.09-0.57), Duration of surgery (SMD: 0.47; 95% CI: 0.19-0.75) and preoperative serum albumin level (SMD: 0.56; 95% CI: 0.14-0.98). The relatively high PIs incidence among patients undergoing open heart surgery suggests that typical PI prevention methods are insufficient for this population. Targeted prevention measures must be developed and implemented.

ABSTRACT

BACKGROUND: Young children are spending an increasing amount of time in non-parental childcare. Despite this trend, few studies have examined how the intensity of non-parental childcare associates with mental health in parents, particularly taking the institutional context concerning childcare into account.

METHODS: Data from the European Union Statistics on Income and Living Conditions EU-SILC (2013) were used to develop a multi-level linear regression model. The sample was restricted to parents in dual-earner couples and with at least one child below the age of three (N=6709). Mental health was assessed using the Mental Health Inventory-5.

RESULTS: Highest levels of mental health were found in parents who use a moderate level of non-parental childcare, while full-time childcare was associated with lower levels of mental health. Working parents reported better mental health in countries where spending on formal childcare was higher, or where using formal childcare use was more widespread for this age group.

CONCLUSIONS: While this study does not allow to establish a causal relationship between the researched indicators, it does indicate that mental-health problems are not randomly distributed among parents but tend to cluster more densely within parents who use higher intensities of childcare and in countries with less supportive childcare policies. Research that ignores social contexts might therefore be limited in terms of generalisation.

ABSTRACT

BACKGROUND: Retaining children for inpatient treatment of complicated severe acute malnutrition (SAM) is a growing challenge until achieved the reference weight of a child. In Ethiopia, there is limited information regarding the time to be lost from the stabilizing centers after initiation of treatment. Thus, this study aimed to identify incidence and predictors of attrition for children suffering from SAM after started inpatient treatment in North West Ethiopia.

METHODS: A retrospective cohort study was conducted among under-five children admitted and started inpatient treatment for complicated SAM from 2015/2016 to 2020/2021. Data were entered using Epi-data version 4.2 and then exported to STATA (SE) version R-14 software for further analysis. The analysis was computed using Cox proportional hazard regression model after checking all proportional hazard assumptions. Covariates having < 0.2 of P values in the bi-variable analysis were candidates transferred to the multivariable Cox proportional hazard regression model. Finally, a statistical significance was declared at a P value of < 0.05.

RESULT: Overall, 760 files of under-five children were analyzed with a mean (± SD) age of participants 27.8 (± 16.5) months. About 6944 child-days of treatment observation were recorded with the crude incidence of attrition rate of 9.7% (95% CI 7.9-12.6). The overall median time of attrition and half-life time S(t_1/2) of survival rates was determined as 14 (IQR = ± 7) days and 91.6% (95% CI 88.2-93.1), respectively. The attrition rate was significantly associated with cases living in rural residents (AHR = 6.03; 95% CI 2.2; 25.2), being re-admitted SAM cases (AHR = 2.99; 95% CI 1.62; 5.5), and caregivers did not have formal education (AHR = :5.6, 95% CI 2.7; 11.7) were all independent predictors for attrition from inpatient treatment.

CONCLUSIONS: Nearly one in every ten severely acute malnourished under-five children defaulted at the end of treatment observation with a median time of 14 (IQR = ± 7) days. Living in a rural residence, being re-admitted cases, caregivers who did not have a formal education were significantly associated with the attrition rate. Hence, it is crucial to detect and control the identified causes of defaulting from treatment observation promptly. Furthermore, serious counseling during admission and nutritional provision strategies are essential for virtuous treatment outcomes.

ABSTRACT

BACKGROUND: High caloric diet and lack of physical activity are considered main causes of NAFLD, and a change in the diet is still the only effective treatment of this disease. However, molecular mechanism of the effectiveness of diet change in treatment of NAFLD is poorly understood. We aimed to assess the involvement of epigenetic mechanisms of gene expression regulation in treatment of NAFLD. Eighteen participants with medium- to high-grade steatosis were recruited and trained to follow the Mediterranean diet modified to include fibre supplements. At three timepoints (baseline, after 30 and 60 days), we evaluated adherence to the diet and measured a number of physiological parameters such as anthropometry, blood and stool biochemistry, liver steatosis and stiffness. We also collected whole blood samples for genome-wide methylation profiling and histone acetylation assessment.

RESULTS: The diet change resulted in a decrease in liver steatosis along with statistically significant, but a minor change in BMI and weight of our study participants. The epigenetic profiling of blood cells identified significant genome-wide changes of methylation and acetylation with the former not involving regions directly regulating gene expression. Most importantly, we were able to show that identified blood methylation changes occur also in liver cells of NAFLD patients and the machine learning-based classifier that we build on those methylation changes was able to predict the stage of liver fibrosis with ROC AUC = 0.9834.

CONCLUSION: Methylomes of blood cells from NAFLD patients display a number of changes that are most likely a consequence of unhealthy diet, and the diet change appears to reverse those epigenetic changes. Moreover, the methylation status at CpG sites undergoing diet-related methylation change in blood cells stratifies liver biopsies from NAFLD patients according to fibrosis grade.
