Correlation between culprit vessel/tirofiban and reperfusion bradyarrhythmia in patients with ST-segment elevation myocardial infarction after emergency PCI

Eur Rev Med Pharmacol Sci. 2021 Aug;25(16):5137-5144. doi: 10.26355/eurrev_202108_26526.

ABSTRACT

OBJECTIVE: To evaluate the correlation between culprit vessel/tirofiban and reperfusion bradyarrhythmia in patients with ST-segment elevation myocardial infarction (STEMI) after emergency percutaneous coronary intervention (PCI).

PATIENTS AND METHODS: A total of 123 STEMI patients undergoing emergency PCI in our hospital from September 2018 to September 2019 were selected and divided into the reperfusion arrhythmias (RA) group (50 cases) and non-RA group (NRA, 73 cases) according to whether RA occurring during PCI. The baseline data such as age and underlying disease were statistically analyzed. Then, the differences were compared between the two groups. According to whether reperfusion bradyarrhythmia (RB) occurring during PCI, 123 STEMI patients were divided into the RB group (63 cases) and non-RB group (60 cases). The relation between culprit vessel/tirofiban and RB was analyzed. ROC curves analysis and multivariate logistic regression were conducted for the risk factors of RA and RB.

RESULTS: Among 123 patients with STEMI after PCI treatment, 73 patients had RA (59.35%), including RB 63 cases and tachyarrhythmia 10 cases. Results of single factor analysis showed that there was statistical significance in 3 factors including the patient age, infarction area and vascular blood flow TIMI classification between RA group and NRA group (p<0.05). ROC curve analysis indicated that the continuous variable patent ages had predictive value in the prevalence of RA, which resulting in an AUC 0.624 and a cut-off pointed age 57 (sensitivity 72.60, specificity 52.00). Multivariate regression analysis showed that the patient age (>57 years old), infarction area in inferior wall and grade 0 lesion vascular blood flow TIMI classification in RA group was significantly higher than that in NRA group (p<0.05). Tirofiban was not associated with RB in STEMI patients treated with emergency PCI, while culprit vessel was statistically significant between RB group and NRB group (p<0.05). Multivariate regression analysis indicated that culprit vessel of the right coronary artery and grade 0 lesions vascular blood flowed TIMI classification was independent risk factors to occurring RB in the STEMI patients with emergency PCI.

CONCLUSIONS: Tirofiban was not associated with RB in STEMI patients treated with emergency PCI. However, it may increase the risk of RB development when the culprit vessel is the right coronary artery. Therefore, timely corresponding treatments and reduction of reperfusion damage are of great significance for those patients.

A Systematic Review and Meta-Analysis Evaluating the Impact of Tranexamic Acid Administration in Aesthetic Plastic Surgery

Aesthet Surg J. 2021 Sep 6:sjab333. doi: 10.1093/asj/sjab333. Online ahead of print.

ABSTRACT

BACKGROUND: Recent evidence suggests tranexamic acid (TXA) may improve outcomes in aesthetic surgery patients.

OBJECTIVES: This systematic review aimed to investigate the impact of TXA use in aesthetic plastic surgery on bleeding and aesthetic outcomes.

METHODS: A systematic literature search was conducted to identify studies evaluating TXA use in aesthetic plastic surgery. The primary outcome of interest was perioperative bleeding, reported as total blood loss (TBL), ecchymosis, and hematoma formation. Meta-analyses analyzing TBL, and postoperative hematoma were performed.

RESULTS: Of 287 identified articles, 14 studies evaluating TXA use in rhinoplasty (6), rhytidectomy (3), liposuction (3), reduction mammaplasty (1), and blepharoplasty (1) were included for analysis. Of 820 total patients, 446 (54.4%) received TXA. Meta-analysis demonstrated TXA is associated with 26.3mL average blood loss reduction (95% CI: -40.0mL to -12.7mL, p < 0.001) and suggested a trend toward decreased odds of postoperative hematoma with TXA use (OR: 0.280, 95% CI: 0.076 – 1.029, p = 0.055). Heterogeneity among reporting of other outcomes precluded meta-analysis; however, 5 of 7 studies found significantly decreased postoperative ecchymosis levels within 7 days of surgery, three studies found statistically significant reductions in postoperative drain output, and one study reported significantly improved surgical site quality for patients who received TXA (p = 0.001).

CONCLUSIONS: TXA is associated with decreased blood loss and a trend toward decreased hematoma formation in aesthetic plastic surgery. Its use has the potential to increase patient satisfaction with postoperative recovery and decrease costs associated with complications, including hematoma evacuation.

Effectiveness of propofol on incidence and severity of emergence agitation on pediatric patients undergo ENT and ophthalmic surgery: Prospective cohort study design

Ann Med Surg (Lond). 2021 Aug 24;69:102765. doi: 10.1016/j.amsu.2021.102765. eCollection 2021 Sep.

ABSTRACT

INTRODUCTION: Emergence agitation is a common problem that can occur after administration of general anesthesia and during recovery time especially in pediatric patients, which can result in life-threatening events if not managed adequately and timely. Usage of modern inhalational anesthetic agents like sevoflurane, isoflurane, and also halothane is a common cause for emergence agitation. Currently, the use of propofol is gaining acceptance largely on decreasing emergence agitation in addition to prevention of postoperative nausea and vomiting. The objective of this study was to assess the effectiveness of prophylaxis administration of propofol on incidence & severity of emergence agitation on pediatric patients undergo ENT & ophthalmic surgery under general anesthesia.

METHODS AND MATERIAL: An institutional-based prospective cohort study was conducted on 90 patients. Patients who take 1 mg/kg of propofol were grouped into exposed while if propofol were not given grouped to non-exposed. Data were collected through intraoperative observation & by using WATCH & PAED score the patients were observed at 5, 15 & 30 min in the recovery room. Incidence of emergence agitation was analyzed by chi-square test & Mann Whitney U test was applied for the severity of emergence agitation. A P-value less than 0.05 was declared as statistically significant.

RESULT: From a total of 90 study participants 64% of the non-exposed group & 31% of the exposed group were developed emergence agitation which was statistically significant with p = 0.002. The severity of agitation was also higher in the non-exposed group than the exposed group at 5, 15 & 30 min with p = 0.009, 0.013, and 0.011 respectively.

CONCLUSION: Administering 1 mg/kg propofol before the end of surgery in pediatrics ENT & ophthalmic procedure under general anesthesia is effective in reducing incidence & severity of emergence agitation. Based on our findings we recommend using 1 mg/kg propofol at the end of surgery to reduce the occurrence of emergency agitation.

Examining risk factors related to digital learning and social isolation: Youth visual acuity in COVID-19 pandemic

J Glob Health. 2021 Aug 21;11:05020. doi: 10.7189/jogh.11.05020. eCollection 2021.

ABSTRACT

BACKGROUND: Around the globe, various self-quarantine, social distancing, and school-closure policies were implemented during the coronavirus disease-19 (COVID-19) outbreak to reduce disease transmission. Many economies/territories were compelled to consider digital learning modalities. In particular, increased digital learning engagement with digital devices and mounting psychosocial stress due to social isolation are likely to pose adverse risks for youth visual health globally. This study examines the association between increased digital device use, psychosocial stress, and myopia symptoms among Chinese youth during the COVID-19 pandemic.

METHODS: This is a retrospective observational population study consisting of 3918 participants enrolled in primary, secondary, and university in China. Participants are recruited through an online survey, which included self-reported information on daily digital device use, psychosocial stress level, condition of visual acuity, and demographic information. We utilize statistical tools including χ2 test, paired sample t test, and multiple multivariate logistic regression.

RESULTS: Each hour increase in digital device use is associated with 1.25 odds ratio OR (95% confidence interval (CI) = 1.21-1.30; P < 0.001) increased risk of developing myopic symptoms, each additional hour of digital device use weighted by near-view and blue-light exposure is associated with OR = 1.04 OR (95% CI = 1.03-1.05; P < 0.001) and OR = 2.25 (95% CI = 1.94-2.60; P < 0.001) increased risk respectively. Subjects reporting under stressful conditions are between OR = 1.98 (95% CI = 1.67-2.36; P < 0.001) and OR = 2.03 (95% CI = 1.71-2.42; P < 0.001) more likely to develop myopic symptoms, relative to those citing less stress.

CONCLUSIONS: The COVID-19 pandemic led to favorable conditions for myopigenic behavioral changes characterized by extended sedentary engagement with digital devices, which are significantly associated with higher risks of myopia incidence. Relatedly, psychosocial stress accompanying prolonged social isolation during the pandemic is a less noticeable, albeit significant risk factor for myopia development.

Socio-economic predictors of undernutrition and anaemia in adolescent mothers in West and Central Africa

J Glob Health. 2021 Aug 10;11:13007. doi: 10.7189/jogh.11.13007. eCollection 2021.

ABSTRACT

BACKGROUND: Adolescence is a formative period when an individual acquires physical, cognitive, emotional, and social resources that are the foundation for later life, health, and well-being [1]. However, in West and Central African region, this trajectory is curtailed by early childbearing associated with an increased risk of undernutrition and anemia. Evidence on socio-economic determinants of anemia and undernutrition in adolescent mothers is limited. This paper aims to shed some light on this issue and, more specifically, assess the socio-economic determinants of anemia among childbearing adolescents in the region.

METHODS: For this observational study, we pooled data from all Demographic and Health Surveys (DHS) conducted in countries in West and Central Africa region between 1986 and 2017. Outcomes were undernutrition and anemia in adolescent mothers. Predictors were education, wealth, place of residence (rural/urban), and religion. Descriptive statistics were calculated using survey weights for individual surveys and in the pooled sample each country was additionally weighted with its population share. We estimated multiple regression models with and without primary sampling unit fixed effects for both outcomes. All regressions were linear probability models.

RESULTS: Having no formal education was the strongest predictor for both anemia and undernutrition. Belonging to the richest asset quintile was also associated with lower anemia and undernutrition prevalence in some specifications. While urban location of the mother was positively associated with anemia, there was no association with undernutrition.

CONCLUSIONS: Overall, having any formal education emerged as a sole strong predictor of reduced adolescent maternal undernutrition and anemia. Promotion of female education can potentially serve as a high-impact intervention to improve adolescent girls’ health in the region. However, we cannot make conclusions about its causal impact based on this study alone.

Stress Classification by Multimodal Physiological Signals Using Variational Mode Decomposition and Machine Learning

J Healthc Eng. 2021 Aug 26;2021:2146369. doi: 10.1155/2021/2146369. eCollection 2021.

ABSTRACT

In this pandemic situation, importance and awareness about mental health are getting more attention. Stress recognition from multimodal sensor based physiological signals such as electroencephalogram (EEG) and electrocardiography (ECG) signals is a very cost-effective way due to its noninvasive nature. A dataset, recorded during the mental arithmetic task, consisting of EEG + ECG signals of 36 participants is used. It contains two categories of performance, namely, “Good” (nonstressed) and “Bad” (stressed) (Gupta et al. 2018 and Eraldeír et al. 2018). This paper presents an effective approach for the recognition of stress marker at frontal, temporal, central, and occipital lobes. It processes the multimodality physiological signals. The variational mode decomposition (VMD) strategy is used for data preprocessing and for the decomposition of signals into various oscillatory mode functions. Poincare plots (PP) are derived from the first eight variational modes and features from these plots have been extracted such as mean, area, and central tendency measure of the elliptical region. The statistical significance of the extracted features with p < 0.5 has been performed using the Wilcoxson test. The multilayer perceptron (MPLN) and Support Vector Machine (SVM) algorithms are used for the classification of stress and nonstress categories. MLPN has achieved the maximum accuracies of 100% for frontal and temporal lobes. The suggested method can be incorporated in noninvasive EEG signal processing based automated stress identification systems.

The Clinical Value of 3D Ultrasonic Measurement of the Ratio of Gestational Sac Volume to Embryo Volume in IoT-Based Prediction of Pregnancy Outcome

J Healthc Eng. 2021 Aug 24;2021:6421025. doi: 10.1155/2021/6421025. eCollection 2021.

ABSTRACT

The objective of the research study is to investigate the use of three-dimensional ultrasonic measurement technology, to determine the size of gestational sac and embryo volume, and to use the ratio of gestational sac volume to embryo volume in IoT-based prediction of pregnancy outcome. The abnormal and normal pregnancy identifiers are there, which assists in prediction of pregnancy outcomes: whether the pregnancy is normal or may suffer pregnancy loss during first trimester. For the observational study, 500 singleton pregnant women who made an appointment for delivery in Qiqihar Hospital from January 2015 to June 2019 were considered. The 500 pregnant women received transvaginal ultrasound at 6+0 ∼ 8+0 weeks of gestational age to measure gestational sac volume (GSV), yolk sac volume (YSV), and germ volume (GV). According to pregnancy outcome, they were divided into fine group (n = 435) and abortion group (n = 65). Among the 500 cases, 435 had normal delivery and 65 had abortions. According to the results of gestational age (GA) analysis, the pregnancy success rates at 6 (n = 268), 7 (n = 184), and 8 weeks (n = 48) were 85.8%, 87.5%, and 91.7%, respectively. Comparison of pregnancy failure rate among the three groups shows statistically significant difference. The morphology of germ, yolk sac, and gestational sac cannot be used as a predictor of pregnancy outcome in various degrees. The results of multivariate Cox proportional regression analysis show the following: the ratio of germ volume (GV) to gestational sac volume (GSV) (P=0.008) has an impact on the prediction of spontaneous abortion prognosis, showing statistically significant difference; yolk sac volume (YSV), germ volume (GV), and gestational sac volume (GSV) have no effect on the prediction of spontaneous abortion prognosis (P > 0.05). The ratio of GSV to germ volume has a strong prognostic value for pregnancy results. To a certain extent, the ratio of gestational sac volume to germ volume can predict spontaneous pregnancy abortion at 6th week of gestation, providing a theoretical basis for clinical ultrasound pregnancy examination indicators.

The Influence of Femoral Internal Rotation on Patellar Tracking in Total Knee Arthroplasty Using Gap Technique

Clin Orthop Surg. 2021 Sep;13(3):352-357. doi: 10.4055/cios20168. Epub 2021 Jun 3.

ABSTRACT

BACKGROUD: Femoral internal rotation in total knee arthroplasty (TKA) is well known as one of the main causes of patellar maltracking. Although femoral internal rotation in TKA is considered unacceptable due to the risk of patellar maltracking, it is sometimes required for ligament balancing. We evaluated the influence of femoral internal rotation on patellar tracking in TKA performed using the gap technique.

METHODS: From April 2008 to May 2018, 1,612 cases of TKA were done. Among them, 245 cases of TKA for osteoarthritis were followed up for at least 1 year and included in this study. We compared patellar tracking in two groups; group I consisted of 99 cases whose femoral rotation was less than 0° and group II consisted of 146 cases whose femoral rotation was 3°-5° external rotation. Preoperative femoral rotation was measured with the condylar twist angle (CTA) by using computed tomography. The patella was replaced in all cases. Patellar tracking was evaluated with patellar tilt angle (lateral tilt [+] and medial tilt [-]) in the merchant radiograph. Statistical analysis was done using Mann-Whitney U-test. Clinical assessment was performed using the Knee Society clinical rating system.

RESULTS: The preoperative CTA was 5.3° ± 1.6° in group I and 5.4° ± 1.6° in group II, showing no statistically significant difference between groups (p = 0.455). Intraoperative femoral rotation was -0.5° ± 0.8° in group I and 3.9° ± 0.8° in group II when the gap technique was used (p < 0.001). The postoperative patellar tilt angle was -0.4° ± 3.6° in group I and 0.1° ± 4.1° in group II with no statistically significant difference (p = 0.251).

CONCLUSIONS: Compared with femoral external rotation, femoral internal rotation with ligament balance in TKA was not more associated with patellar maltracking. Therefore, patellar tracking might be related with ligament balance in flexion regardless of the anatomic femoral rotational alignment.

Comparative Study of Pinless Navigation System versus Conventional Instrumentation in Total Knee Arthroplasty

Clin Orthop Surg. 2021 Sep;13(3):358-365. doi: 10.4055/cios20226. Epub 2021 Apr 12.

ABSTRACT

BACKGROUD: Optimal placement of the components and achieving a neutral mechanical axis are the main goals of total knee arthroplasty (TKA). Different computerised navigation systems are presently used for these purposes. This aim of this study was to compare the pinless navigation (PNA) TKA performed using iAssist with the conventional instrumented (CIN) TKA in terms of functional and radiological outcomes.

METHODS: A total of 100 knees operated for TKA by a single surgeon were studied retrospectively for a period of 2 years. Weight-bearing postoperative radiographs of the knees along with scanograms of the lower limbs were used for measurements of component positioning, mechanical axis alignment, and number of outliers. Oxford knee scoring was used for functional analysis.

RESULTS: No statistically significant difference was seen in the mean mechanical axis alignment (hip-knee-ankle angle), coronal alignment (α and β angles) and sagittal alignment (γ and δ angles) of the femoral and tibial components between the two groups. Though the percentage of outliers for mechanical axis alignment was lower in the PNA-TKA group than in the CIN-TKA group, the difference was not statistically significant (p = 0.73). The number of outliers for the femoral and tibial component positioning in coronal and sagittal planes was not statistically significantly different between the two groups. No statistically significant difference (p = 0.68) was noted between the two groups with respect to the Oxford Knee Score. The mean surgical time was greater in the PNA-TKA group by 11 minutes, which was statistically significantly longer (p = 0.018). Complications were seen in 6.89% of the cases in the CIN-TKA group, while none in the PNA-TKA group.

CONCLUSIONS: The accurate mechanical axis alignment and component positioning can be achieved with the conventional instrumentation, so the use of PNA system, which adds to the surgical cost, is questionable. Also, equally good short-term functional outcome can be achieved with the conventional instrumentation. The surgeon must be accustomed with the instrumentation of the PNA system, or it adds to the surgical time.

A retrospective cone beam computed tomography analysis of cemento-osseous dysplasia

J Dent Sci. 2021 Oct;16(4):1154-1161. doi: 10.1016/j.jds.2021.03.009. Epub 2021 Apr 7.

ABSTRACT

BACKGROUND/PURPOSE: Radiological examination is indispensable in the diagnosis and follow-up of cemento-osseous dysplasia (COD). The aim of this retrospective study was to describe a series of COD cases, identify the frequencies of COD subtypes, and investigate the demographic and radiological characteristics in relation to subtypes.

MATERIALS AND METHODS: Cone beam computed tomography (CBCT) images/reports of patients with a diagnosis of COD were included in the study. The data collected included information on the age, sex, subtype of COD, location of COD, and region involved. Information regarding the internal density, effects on surrounding structures, and presence of concomitant lesions was also collected. The data obtained were evaluated statistically.

RESULTS: The study group included CBCT images of 142 patients (130 females (91.5%) and 12 males (8.5%)) with a mean age of 46.97 ± 10.57 years. The mandible was involved in almost all cases (99.3%). The most common subtype was florid COD (51.4%) and lesions with hyperdense internal density (81.7%) were more commonly observed. Cortical thinning (78.2%) was a prominent feature. The frequency of root resorption in periapical COD cases (57.1%) was observed to be significantly higher (p < 0.05). All hypercementosis cases were associated with florid subtype (p < 0.05). In a minority of cases (6.3%), the lesions were associated with bone cysts and osteomyelitis.

CONCLUSION: CBCT images clearly demonstrated the effect of COD lesions on surrounding structures. CBCT is an appropriate imaging modality for the diagnosis and follow-up of COD which is the most common fibro-osseous lesion in clinical practice.
