ABSTRACT

BACKGROUND: In spite of, the need for evidence-based intervention on the potential harmful effects of self-medication practices during pregnancy, there is no systematic review and meta-analysis study regarding self-medication practices in Ethiopia. Therefore, the aim of this study is to determine prevalence of self-medication practice and associated factors among pregnant women in Ethiopia.

METHOD: We used PubMed, the Cochrane Library, Google Scholar, the Wiley Online Library, and African Journals Online to choose important studies. The I-squared statistic method was used to check for heterogeneity between studies. Random effect model was used to estimate the pool prevalence of self-medication among pregnant women. Publication bias was determined by the funnel plot and Egger’s test.

RESULT: A total of 11 studies with 4643 study participants were included in this review. The finding from the current meta-analysis showed that the overall prevalence of self-medication practice among pregnant women is 33.92% (95% CI: 23.15-44.70, I² value = 80.9%). First trimester of pregnancy (OR: 2.24, 95% CI: 1.44-3.47), women who faced health problems during pregnancies at the moment (OR: 5.7, 95% CI: 3.92-8.29), previous self-medication practice (OR: 13.07, 95% CI: 5.14-33.25) and previous pregnancy-related problems (OR: 2.065, 95% CI: 1.44-2.96) were positively associated with self-medication practice among pregnant women.

CONCLUSION: The prevalence of self-medication practices among pregnant women is found to be high. Self-medication practices of the pregnant women were significantly higher among women who were in first-trimester pregnancy, encountered illness during pregnancy, previous self-medication history, and previous pregnancy-related problems.Prospero registration number: CRD42023394907.

ABSTRACT

BACKGROUND AND PURPOSE: In large vessel occlusion (LVO) stroke patients, relative cerebral blood flow (rCBF)<30% volume thresholds are commonly used in treatment decisions. In the early time window, nearly infarcted but salvageable tissue volumes may lead to pretreatment overestimates of infarct volume, and thus potentially exclude patients who may otherwise benefit from intervention. Our multisite analysis aims to explore the strength of relationships between widely used pretreatment CT parameters and clinical outcomes for early window stroke patients.

METHODS: Patients from two sites in a prospective registry were analyzed. Patients with LVOs, presenting within 3 hours of last known well, and who were successfully reperfused were included. Primary short-term neurological outcome was percent National Institutes of Health Stroke Scale (NIHSS) change from admission to discharge. Secondary long-term outcome was 90-day modified Rankin score. Spearman’s correlations were performed. Significance was attributed to p-value⩽.05.

RESULTS: Among 73 patients, median age was 66 (interquartile range 54-76) years. Among all pretreatment imaging parameters, rCBF<30%, rCBF<34%, and rCBF<38% volumes were significantly, inversely correlated with percentage NIHSS change (p<.048). No other parameters significantly correlated with outcomes.

CONCLUSIONS: Our multisite analysis shows that favorable short-term neurological recovery was significantly correlated with rCBF volumes in the early time window. However, modest strength of correlations provides supportive evidence that the applicability of general ischemic core estimate thresholds in this subpopulation is limited. Our results support future larger-scale efforts to liberalize or reevaluate current rCBF parameter thresholds guiding treatment decisions for early time window stroke patients.

ABSTRACT

AIM: To clarify the state of screening and support systems for socially high-risk pregnant women at obstetric facilities across Japan and identify the characteristics of facilities related to the implementation of screening.

METHODS: This cross-sectional study used a self-administered questionnaire. Participants were managers of hospitals, clinics, and midwifery birth centers handling deliveries in 47 prefectures across Japan. The questionnaire comprised items regarding the characteristics of participants and their facilities, service provision related to socially high-risk women available at the facility, the number of specified pregnant women (tokutei ninpu) per year, methods of screening, and support systems within the obstetric facilities. Descriptive statistics and multivariate logistic regression analysis were performed using IBM-SPSS version 24 for the association between facility characteristics and screening practices for socially high-risk pregnant women.

RESULTS: Valid responses were received from 716 of 2512 obstetric facilities. Rates of specified expectant mothers per annual number of deliveries were identified as follows: perinatal medical centers (2.7%), general hospitals (1.6%), obstetrics and gynecology hospitals (1.0%), and clinics (0.8%). A total of 426 facilities (60.6%) reported screening all expectant mothers to identify socially high-risk pregnant women. Multiple logistic regression analysis revealed that facility characteristics and service/care provision related to screening practices included availability of in-hospital midwife-led care and in-hospital midwifery clinics (adjusted odds ratio 1.61; 95% CI [1.30, 1.47]), one-on-one care by midwife (1.73; 95% CI [1.15, 2.59]), multidisciplinary meetings within the facility (1.70; 95% CI [1.14, 2.56]), follow-up support systems after discharge (1.90; 95% CI [1.17, 3.09]), and participation in the regional council for children in need of protection (2.33; 95% CI [1.13, 4.81]).

CONCLUSIONS: Approximately 60% of surveyed obstetric facilities screen for socially high-risk women. Increasing service provision at facilities may be necessary to implement screening.

ABSTRACT

Escalating proportions of industrially contaminated sites are one of the major catastrophes faced at the present time due to the industrial revolution. The difficulties associated with culturing the microbes, has been circumvent by the direct use of metagenomic analysis of various complex niches. In this study, a metagenomic approach using next generation sequencing technologies was applied to exemplify the taxonomic abundance and metabolic potential of the microbial community residing in Amlakhadi canal, Ankleshwar at two different seasons. All the metagenomes revealed a predominance of Proteobacteria phylum. However, difference was observed within class level where Gammaproteobacteria was relatively high in polluted metagenome in Summer while in Monsoon the abundance shifted to Betaproteobacteria. Similarly, significant statistical differences were obtained while comparing the genera amongst contaminated sites where Serratia, Achromobacter, Stenotrophomonas and Pseudomonas were abundant in summer season and the dominance changed to Thiobacillus, Thauera, Acidovorax, Nitrosomonas, Sulfuricurvum, Novosphingobium, Hyphomonas and Geobacter in monsoon. Further upon functional characterization, the microbiomes revealed the diverse survival mechanisms, in response to the prevailing ecological conditions (such as degradation of aromatic compounds, heavy metal resistance, oxidative stress responses and multidrug resistance efflux pumps, etc.). The results have important implications in understanding and predicting the impacts of human-induced activities on microbial communities inhabiting natural niche and their responses in coping with the fluctuating pollution load.

ABSTRACT

BACKGROUND: Non-chromosomal birth defects are an important risk factor for several childhood cancers. However, these associations are less clear for Hodgkin lymphoma (HL). Therefore, we sought to more fully elucidate the association between non-chromosomal birth defects and HL risk.

PROCEDURE: Information on cases (n = 517) diagnosed with HL (ages of 0-14) at Children’s Oncology Group Institutions for the period of 1989-2003 was obtained. Control children without a history of cancer (n = 784) were identified using random digit dialing and individually matched to cases on sex, race/ethnicity, age, and geographic location. Parents completed comprehensive interviews and answered questions including whether their child had been born with a non-chromosomal birth defect. To test the association between birth defects and HL risk, conditional logistic regression was applied to generate adjusted odds ratios (aORs) and 95% confidence intervals (CIs).

RESULTS: Children born with any non-chromosomal birth defect were not more likely to be diagnosed with HL at 0-14 years of age (aOR: 0.91; 95% CI: 0.69-1.21). No associations were detected between major or minor birth defects and HL (aOR: 1.34; 95% CI: 0.67-2.67 and aOR: 0.88; 95% CI: 0.57-1.34, respectively). Similarly, no association was observed for children born with any birth defect and EBV-positive HL (aOR: 0.57; 95% CI: 0.25-1.26).

CONCLUSIONS: Previous assessments of HL in children with non-chromosomal birth defects have been limited. Using data from the largest case-control study of HL in those <15 years of age, we did not observe strong associations between being born with a birth defect and HL risk.

ABSTRACT

BACKGROUND: Foetal alcohol spectrum disorders (FASD) include somatic and neurological developmental disturbances after prenatal alcohol exposure, including facial anomalies. However, the knowledge of the orthodontic skeletal and dental cephalometric relations in this group is limited. The aim of the study was to assess the dentofacial characteristics of children and adolescents with FASD and to compare them with a matched control group.

METHODS: The study group comprised all available children and adolescents diagnosed with FASD (> 7 years of age) in whom good quality cephalograms were available. The control group comprised non-syndromic, orthodontically untreated children with normal occlusion and skeletal relations matched with age and gender. Cephalometric analysis included eighteen linear and angular measurements. The general linear model for repeated measures regarding age, gender and the type of FASD was applied.

RESULTS: The group with FASD included 35 individuals (21 girls and 14 boys) aged 7-18 years including 21 with foetal alcohol syndrome. The mean age in the study and the control group was 12.8 years (SD, range 3.2, 7.1-18.1) and 13.0 (SD, range 2.9, 9.1-18.1), respectively. Statistically significant differences between the groups were found in 15 out of 18 of the cephalometric measurements (83%). In children with FASD the mandible was more retrusive, the incisors were more proclined and the mandibular incisors and the lips were more protruded when compared with controls. There was no significant evidence of an influence of age, gender or FASD type.

CONCLUSIONS: Dentofacial characteristics of children and adolescents with FASD significantly differ from controls. Early orthodontic diagnosis and prophylaxis should play a part of the interdisciplinary care of patients in this group.

ABSTRACT

Although arterial stiffness measured by brachial-ankle pulse wave velocity (baPWV) and blood pressure (BP) significantly correlated, the relationship between baPWV and BP variation (BPV) was unclear. This study aimed to examine the temporal relationship between brachial-ankle pulse wave velocity (baPWV) and systolic blood pressure variation (SBPV) and their joint effect on the development of cardiovascular disease (CVD). This study included 6632 participants with repeated assessments of baPWV and BP during 2006 to 2018. The baseline and follow-up SBPV was calculated as absolute SBP difference divided by mean SBP over sequential visits, using data between 2006-2010 and 2014-2018, respectively. Cross-lagged analysis was used to assess the temporal relation between baPWV and SBPV, and logistic analysis was used to assess the joint effect of baPWV and SBPV on CVD. After adjustment for confounder, the path coefficient from baseline baPWV to follow-up SBPV (β₁ = 0.040; P = 0.0012) was significantly had greater than the path from baseline SBPV to follow-up baPWV (β₂ = 0.009; P = 0.3830), with P = 0.0232 for the difference between β₁ and β₂. This unidirectional relationship from baseline baPWV to follow-up SBPV was consistent in patients without hypertension, with isolated systolic, high systolic and diastolic, uncontrolled and controlled hypertension. In addition, participants with high levels of baseline baPWV and follow-up SBPV had greater risk of CVD (odds ratio, 5.82; 95% confidence interval, 2.50-12.60) than those with low-low levels. The findings suggested that arterial stiffness appeared to precede the increase in SBPV and their joint effect is predictive of the development of CVD.

ABSTRACT

OBJECTIVE: Our goal was to improve placement success rates for peripheral arterial line (PAL) placements by introducing an ultrasound-guided (USg) approach. Our aim was to maintain success rates over 70% within 18 months.

STUDY DESIGN: Interventions included development of a training curriculum, and procedure standardization. Among 302 patients, 115 underwent USg catheter placement; the traditional method was used in 187 patients. Outcome measures were first-attempt and overall success rates. Process measures were proportion of PALs placed under US guidance, trainer availability, and trainee sign-off. Line complications were balancing measures. Statistical process control charts were used to monitor metrics.

RESULTS: Sustained improvement was seen with the USg approach. The USg approach had first and overall attempt success by the trainers (i.e., independent users) of 83.7% (77/92) and 96.5% (111/115), compared to 50.3% (82/163) and 73.8% (138/187) with the traditional approach.

CONCLUSION: Introducing the USg approach had a significant impact on PAL placement success in neonatal patients.

ABSTRACT

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) are common adverse events in patients undergoing emetogenic chemotherapy. Palonosetron, a second-generation 5-hydroxytryptamine-3 receptor antagonist (5-HT3 RA), has demonstrated non-inferiority to first-generation 5-HT3 RAs for CINV in pediatric patients. Although palonosetron has a long half-life and prolonged antiemetic action, its efficacy against delayed CINV in pediatric patients is not well understood. Therefore, this meta-analysis of randomized controlled trials (RCTs) aimed to evaluate the efficacy of palonosetron for delayed CINV in pediatric patients.

METHODS: A literature search of MEDLINE/PubMed, Embase, Cochrane Library, and Web of Science databases was performed. A meta-analysis was performed using forest plots, and risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. A funnel plot was constructed to explore publication bias.

RESULTS: The literature search retrieved 842 records, of which 23 full-text articles were assessed, including six RCTs. Meta-analysis of four RCTs that reported on the complete response (CR: defined as no emesis and no rescue medication) rate for delayed CINV revealed that palonosetron was statistically superior to first-generation 5-HT3 RAs (RR = 1.21 [95% CI 1.09-1.35]; p < 0.01). Although the number of studies included was small, no publication bias was observed in the funnel plots. In addition, the CR rate for overall and acute CINV was also significantly higher for palonosetron (RR = 1.25 [95% CI 1.01-1.54]; p = 0.04 and RR = 1.06 [95% CI 1.01-1.12]; p = 0.03, respectively).

CONCLUSION: Palonosetron is effective in the prophylaxis of delayed CINV in pediatric patients.

ABSTRACT

This paper presents the results of a series of surveys conducted from July 2021 to March 2023 to investigate the post-vaccination adverse reactions to the mRNA-1273 (Moderna) vaccine among faculty, staff, and students at Okayama University. These studies complement the official surveys conducted by the Ministry of Health, Labour and Welfare (MHLW) and provide a more representative picture of adverse reactions in the general population including large numbers of healthy young people. Pain, swelling, redness at the injection site, fever, headache, and malaise were the main adverse reactions reported. The proportion of adverse reactions was generally higher after the second vaccination and decreased with each additional vaccination. No statistically significant differences in the adverse reactions were found for males and females and those with/without a history of allergy, but a lower proportion of fever was observed in older participants and those with underlying medical conditions. We also evaluated the association between adverse reactions and antibody titers after the third vaccination and found no significant differences in antibody levels one month after vaccination. This series of studies highlights the importance of conducting surveys in diverse populations to provide a more representative picture of post-vaccination adverse reactions during a pandemic.
