Tactile perception of randomness: Effect of varying stimulus size and participants age.

We investigated participants' ability to differentiate between random and organized two-dimensional tactile tiles with embossed dots and examined how this ability varies with size and participant age. Four experiments were conducted to evaluate the effect of these variations on participants' capacity to utilize touch in identifying which of two stimuli exhibited greater randomness. Participants were instructed to explore embossed tiles using both hands. The tiles had varying levels of randomness from organized to random sets. In Experiments 1, 2, and 4, the sets were of equal size, while in Experiment 3, they differed in size. Results revealed a significant difference between the random and organized sets, with random stimuli being more easily discernible. These findings suggest that touch can be utilized to discern random patterns on tactile maps or displays. However, older participants encountered difficulties making this distinction, indicating similarities between vision and touch in perceiving randomness.

Meta-analysis of the relation between irritable bowel syndrome and antibodies against endogenous gonadotropin-releasing hormone and its receptor.

This meta-analysis assessed the association between gonadotropin hormone-releasing hormone (GnRH) antibodies and irritable bowel syndrome (IBS). We defined a search strategy and implemented it with PubMed, Ovid, Scopus, and Web of Science databases for English language publications. The data were evaluated for acceptability, and randomized controlled studies as well as case-control, cross-sectional, and cohort studies reporting the prevalence of GnRH antibodies in IBS patients were included. The total number of patients in the included studies was 1095: 270 patients in the IBS group and 825 patients in the control group. By comparing the IBS group and the control group, we found a statistically significant association between IBS and the increased prevalence of GnRH IgM antibodies (risk ratio = 2.29, 95% confidence interval = 1.58 to 3.31, P < 0.0001). We also found a statistically significant association between IBS and increased prevalence of GnRH receptor IgM antibodies compared with controls (risk ratio = 3.80, 95% confidence interval = 1.72 to 8.38, P = 0.001). The meta-analysis revealed a statistically significant association between IBS and increased prevalence of GnRH IgM and GnRH receptor IgM antibodies.

Cosmetic operative care abroad leads to a multidrug-resistant Mycobacterium abscessus infection in a patient: a case report.

INTRODUCTION: The Mycobacterium abscessus complex is a nontuberculous mycobacteria species that is pervasive in soil and water. Various medical equipment malfunctions, infected surfaces, and patient transmission are potential causes of Mycobacterium abscessus infection in the hospital environment. These cases have an annual prevalence that ranges from 1.4 to 6.6 per 100,000 infections, mainly increasing. CASE PRESENTATION: We present the case of a 23-year-old American female patient who presented to the emergency room with significant abdominal pain between low pelvic sutures and the umbilicus. She reported abdominal pain, pruritus, and boils on her back preventing her from standing upright. The symptoms occurred in the liposuction area after cosmetic surgery in the Dominican Republic. The clinical, radiological, and cultural findings helped diagnose Mycobacterium abscessus infection. We conducted a mini literature review on the published reports of Mycobacterium abscessus. CONCLUSION: Mycobacterium abscessus infection may occur due to surgical procedures abroad. Measures are required to combat Mycobacterium abscessus and reduce its prevalence in hospital settings.

Relation Between Familial Mediterranean Fever and QT Markers (QTc, QTd, and QTcd): A Systematic Review and Meta-Analysis.

The aim of this study is to perform a meta-analysis to evaluate the possible association betweenQT markers and familial Mediterranean fever (FMF). PUBMED, Web of Science, OVID, and SCOPUS databases were searched. Inclusion criteria were randomized control trials or observational studies that compared measurement of the QT markers in FMF patients and healthy controls in both males and females without any age restriction or other comorbidities. RevMan software (5.4) was used to perform the analysis. A total of 14 studies with 1,154 individuals were included in the study. The pooled effect estimate showed a statistically significant association between FMF group and prolonged corrected QT (QTc) and QT dispersion (QTd) (MD= 7.06, 95% CI = 2.68 to 11.43, p-value = 0.002) and (MD= 6.08, 95% CI = 0.84 to 11.32, p-value= 0.02), respectively. No statistically significant difference between FMF group and QT interval and corrected QT dispersion (QTcd) (MD= 2.34, 95% CI = -1.21 to 5.89, p-value = 0.20) and (MD= 4.82, 95% CI = -0.57 to 10.20, p-value = 0.08), respectively. Our findings revealed a statistically significant relationship between FMF and extended QTc and QTd. More randomized multicenter trials are required to confirm our findings.

The prognostic value of neutrophil-to-lymphocyte ratio in patients with traumatic brain injury: A systematic review.

Traumatic brain injury (TBI) places a heavy load on healthcare systems worldwide. Despite significant advancements in care, the TBI-related mortality is 30-50% and in most cases involves adolescents or young adults. Previous literature has suggested that neutrophil-to-lymphocyte ratio (NLR) may serve as a sensitive biomarker in predicting clinical outcomes following TBI. With conclusive evidence in this regard lacking, this study aimed to systematically review all original studies reporting the effectiveness of NLR as a predictor of TBI outcomes. A systematic search of eight databases was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analyses statement (PRISMA) recommendations. The risk of bias was assessed using the Quality in Prognostic Studies (QUIPS) tool. Eight studies were ultimately included in the study. In most of the studies interrogated, severity outcomes were successfully predicted by NLR in both univariate and multivariate prediction models, in different follow-up durations up to 6 months. A high NLR at 24 and 48 h after TBI in pediatric patients was associated with worse clinical outcomes. On pooling the NLR values within studies assessing its association with the outcome severity (favorable or not), patients with favorable outcomes had 37% lower NLR values than those with unfavorable ones (RoM= 0.63; 95% CI = 0.44-0.88; p = 0.007). However, there were considerable heterogeneity in effect estimates (I 2 = 99%; p < 0.001). Moreover, NLR was a useful indicator of mortality at both 6-month and 1-year intervals. In conjunction with clinical and radiographic parameters, NLR might be a useful, inexpensive marker in predicting clinical outcomes in patients with TBI. However, the considerable heterogeneity in current literature keeps it under investigation with further studies are warranted to confirm the reliability of NLR in predicting TBI outcomes.

A problem of self-isolation in Japan: The relationship between self-isolation and COVID-19 community case.

Background: The Japanese government advised mild or asymptomatic coronavirus disease-2019 (COVID-19) cases to self-isolate at home, while more severe individuals were treated at health posts. Poor compliance with self-isolation could be a potential reason for the new outbreak. Our study aimed to find out the correlation between the rising new cases of COVID-19 and home-based patients in Japan. Methods: A secondary data analysis study was conducted with the data from COVID-19- involved databases collected from Johns Hopkins University, Japanese Ministry of Health, Labour and Welfare, and Community Mobility Reports of Google. New community cases, stringency index, number of tests, and active cases were analyzed. Using a linear regression model, an independent variable was utilized for a given date to predict the future number of community cases. Results: Research results show that outpatient cases, the stringency, and Google Mobility Trend were all significantly associated with the number of COVID-19 community cases from the sixth day to the ninth day. The model predicting community cases on the eighth day (R2=0.8906) was the most appropriate showing outpatients, residential index, grocery and pharmacy index, retail and recreation index, and workplaces index were positively related (ß1=24.2, 95% CI: 20.3- 26.3, P<0.0001; ß2=277.7, 95% CI: 171.8-408.2, P<0.0001; ß3=112.4, 95% CI: 79.8-158.3, P<0.0001; ß4=73.1, 95% CI: 53- 04.4, P<0.0001; ß5=57.2, 95% CI: 25.2-96.8, P=0.001, respectively). In contrast, inpatients, park index, and adjusted stringency index were negatively related to the number of community cases (ß6=-2.8, 95% CI: -3.9 - -1.6, P<0.0001; ß7=-33, 95% CI: -43.6 - -27, P<0.0001; ß8=-14.4, 95% CI: -20.1- -12, P<0.0001, respectively). Conclusion: Outpatient cases and indexes of Community Mobility Reports were associated with COVID-19 community cases.

Afghan Health Related Concerns Following the US Withdrawal: Results of a Survey Given via Social Media.

Background: The United States Armed Forces completed their withdrawal from Afghanistan on August 30th, 2021, ending 20 years of war in Afghanistan. This rapid timeline from announcement to withdrawal and subsequent power transfer had profound consequences on the Afghan people, particularly in the domains of health and healthcare. Methods: On 15 September 2021, we posted an anonymous online cross-sectional survey on social media (Twitter, Facebook, and WhatsApp groups) to collect data about respondents from Afghanistan. Questions focused on COVID-19 symptoms, concerns, and individual care with a focus on changes related to the United States (US) withdrawal from Afghanistan. The form was composed of 17 questions which included multiple choice, single choice, and numeric options. All questions were optional including demographic data. Results: Our survey yielded 1,074 responses from the Farsi version and 572 responses from the Pashto version for a total of 1,646 responses. 1,286 (80%) of respondents were in Afghanistan at the time of survey submission. Concerning the US withdrawal from Afghanistan, 26% (412) respondents were extremely concerned and 12% (181) were moderately concerned. A majority of respondents report concerns regarding mental health due to the US withdrawal. 27% (418) report extreme concern, 12% (186) report moderate concern, and 15% (229) report a little concern. There is a significant difference in the proportions of concern (for US withdrawal generally, as well as physical and mental health) across gender. 49% of Female respondents report extreme concern regarding the US withdrawal compared to 22% of Male respondents (P < 0.001). With respect to physical health concerns 36% of Females report extreme concern compared to 16% of Males (P < 0.001). Finally on the mental health concerns, 54% of Females report extreme concern compared to 22% of Males (P < 0.001). Conclusion: The results from this survey are susceptible to the possibility of internal validity and/or external validity. However, we are accepting of those possibilities considering this survey wasn't designed to be bulletproof, but rather serve as a voice for those who can't be heard and to inform the public of the hardships occurring across the globe due to a steadfast retraction of the US footprint from their soil. Our findings indicate salient changes and public health concerns among Afghans following the US withdrawal from the region. These concerns varied across gender and ethnic groups. Our findings may serve as the first step in addressing the health concerns of Afghans following two decades of US military presence. The results should be understood through the limitations associated with a survey study design. Future research and policy aimed at tackling short and long-term health and social concerns in Afghanistan should consider the role of US withdrawal.

Association of familial Mediterranean fever and epicardial adipose tissue: A systematic review and meta-analysis.

Background and Aim: Some studies reported a positive link between familial Mediterranean fever (FMF) and epicardial adipose tissue. Our meta-analysis aimed to evaluate whether there is a significant association between FMF and increased epicardial adipose tissue thickness. Methods: We searched the following databases: PUBMED, WOS, OVID, SCOPUS, and EMBASE. Inclusion criteria were any original articles that reported epicardial adipose tissue in FMF patients with no age restriction, excluding reviews, case reports, editorials, animal studies, and non-English studies. Thirty eligible studies were screened full text but only five studies were suitable. We used RevMan software (5.4) for the meta-analysis. Results: The total number of patients included in the meta-analysis in the FMF patients group is 256 (mean age = 24.3), and the total number in the control group is 188 (mean age = 24.98). The pooled analysis between FMF patients and controls was [mean difference = 0.82 (95% CI = 0.25-1.39), p-value = 0.005]. We observed heterogeneity that was not solved by random effects (p > 0.00001). We performed leave one out test by removing the Kozan et al. study, and the heterogeneity was solved (p = 0.07), and the results were (MD = 0.98, 95% CI = 0.52-1.43, p-value < 0.0001). Conclusion: FMF patients are at increased risk of developing epicardial adipose tissue compared to controls. More multicenter studies with higher sample sizes are needed to support our results.

Neuroprotection in Acute Ischemic Stroke: A Battle Against the Biology of Nature.

Stroke is the second most common cause of global death following coronary artery disease. Time is crucial in managing stroke to reduce the rapidly progressing insult of the ischemic penumbra and the serious neurologic deficits that might follow it. Strokes are mainly either hemorrhagic or ischemic, with ischemic being the most common of all types of strokes. Thrombolytic therapy with recombinant tissue plasminogen activator and endovascular thrombectomy are the main types of management of acute ischemic stroke (AIS). In addition, there is a vital need for neuroprotection in the setting of AIS. Neuroprotective agents are important to investigate as they may reduce mortality, lessen disability, and improve quality of life after AIS. In our review, we will discuss the main types of management and the different modalities of neuroprotection, their mechanisms of action, and evidence of their effectiveness after ischemic stroke.

Efficacy of heads-up CPR compared to supine CPR positions: Systematic review and meta-analysis.

Background and Aim: Cardiopulmonary resuscitation (CPR) in full-coded patients requires effective chest compressions with minimal interruptions to maintain adequate perfusion to the brain and other vital organs. Many novel approaches have been proposed to attain better organ perfusion compared to traditional CPR techniques. The purpose of this review is to investigate the safety and efficacy of heads-up CPR versus supine CPR. Methods: We searched PubMed Central, SCOPUS, Web of Science, and Cochrane databases from 1990 to February 2021. After the full-text screening of 40 eligible studies, only seven studies were eligible for our meta-analysis. We used the RevMan software (5.4) to perform the meta-analysis. Results: In survival outcome, the pooled analysis between heads-up and supine CPR was (risk ratio = 0.98, 95% confidence interval [CI] = 0.17-5.68, p = 0.98). The pooled analyses between heads-up CPR and supine CPR in cerebral flow, cerebral perfusion pressure and coronary perfusion pressure outcomes, were (mean difference [MD] = 0.10, 95% CI = 0.03-0.17, p = 0.003), (MD = 12.28, 95% CI = 5.92-18.64], p = 0.0002), and (MD = 8.43, 95% CI = 2.71-14.14, p = 0.004), respectively. After doing a subgroup analysis, cerebral perfusion was found to increase during heads-up CPR compared with supine CPR at 6 min CPR duration and 18 to 20 min CPR duration as well. Conclusion: Our study suggests that heads-up CPR is associated with better cerebral and coronary perfusion compared to the conventional supine technique in pigs' models. However, more research is warranted to investigate the safety and efficacy of the heads-up technique on human beings and to determine the best angle for optimization of the technique results.

Prehospital administration of broad-spectrum antibiotics for sepsis patients: A systematic review and meta-analysis.

Background and Aims: Some studies have suggested that earlier initiation of antibiotics has shown positive outcomes in sepsis patients. We aimed to do a systematic review and meta-analysis to evaluate the effect of prehospital administration of antibiotics on 28 days mortality and length of stay in hospital and intensive care unit for sepsis patients. Methods: We formulated a search strategy and used it on search databases PubMed, Scopus, Web of Science, and Embase. We then screened the records for eligibility and included controlled studies, either clinical trials or cohort studies reporting prehospital antibiotic administration for sepsis patients. We excluded duplicates, books, conferences' abstracts, case reports, editorials, letters, author responses, not English studies, and studies with nonavailable full text. Animal and lab studies were also excluded. Results: The total number of studies identified is 1811, 19 were eligible for systematic review and 4 for meta-analysis (three cohort and one clinical trial). The total number of sepsis patients in the four included studies in the 28 days mortality outcome was 3523 (1779 took prehospital antibiotics and 1744 did not take prehospital antibiotics). Of 1779 who took the antibiotics, 190 died, and of 1744 who did not take antibiotics, 292 died (95% confidence interval 0.68-0.97, p = 0.02). Conclusion: This meta-analysis reveals that receiving prehospital antibiotics can significantly lower mortality in sepsis patients compared to patients who do not receive prehospital antibiotics. However, more clinical trials and multicenter prospective studies with high sample sizes are needed to get strong evidence supporting our findings.

Simple headache revealed a rare lymphoma: Waldenstrom macroglobulinemia with unique markers: a case report and review of the literature.

BACKGROUND: Waldenstrom macroglobulinemia (WM) is a rare lymphoma with an incidence rate of 3 per million people per year, with approximately 1000 to 1500 new cases diagnosed each year in the USA. It is primarily seen in Caucasian males with a median age of 70 years old. Patients are most often asymptomatic, but WM can manifest itself with constitutional symptoms such as lethargy, bleeding, organomegaly, and neurological or fundoscopic abnormalities. WM is characterized by immunoglobulin M (IgM) monoclonal gammopathy, lymphocytic infiltration of bone marrow, and normocytic anemia due to bone marrow replacement. CASE PRESENTATION: Our patient is a Hispanic 67-year-old female that presents with one month of intermittent band-like bilateral headache accompanied by dizziness, light-headedness, nausea, and blurred vision. A thorough diagnostic workup was performed, including serum protein electrophoresis (SPEP) with serum immunofixation (SIFE) showing an M spike and IgM kappa. Bone marrow biopsy was significant for lymphoplasmacytic infiltration with nodular B cells (CD19+, CD20+, CD22+). Computerized Tomography (CT) imaging showed splenomegaly in the patient. Treatment was provided for hyperviscosity syndrome with plasmapheresis twice. The patient reported improvement of her symptoms and was then scheduled for chemotherapy. Throughout 7 months, our patient received multiple cycles of bortezomib, dexamethasone, and rituximab. While her symptoms improved her psychiatric status got progressively worse. CONCLUSION: It is important not to neglect symptoms such as a headache, which may seem small, but could serve as a clue in the diagnosis of Waldenstrom's macroglobulinemia.

Physical activity level and stroke risk in US population: A matched case-control study of 102,578 individuals.

BACKGROUND: Stroke has been linked to a lack of physical activity; however, the extent of the association between inactive lifestyles and stroke risk has yet to be characterized across large populations. PURPOSE: This study aimed to explore the association between activity-related behaviors and stroke incidence. METHODS: Data from 1999 to 2018 waves of the concurrent cross-sectional National Health and Nutrition Examination Survey (NHANES) were extracted. We analyzed participants characteristics and outcomes for all participants with data on whether they had a stroke or not and assessed how different forms of physical activity affect the incidence of disease. RESULTS: Of the 102,578 individuals included, 3851 had a history of stroke. A range of activity-related behaviors was protective against stroke, including engaging in moderate-intensity work over the last 30 days (OR = 0.8, 95% CI = 0.7-0.9; P = 0.001) and vigorous-intensity work activities over the last 30 days (OR = 0.6, 95% CI = 0.5-0.8; P < 0.001), and muscle-strengthening exercises (OR = 0.6, 95% CI = 0.5-0.8; P < 0.001). Conversely, more than 4 h of daily TV, video, or computer use was positively associated with the likelihood of stroke (OR = 11.7, 95% CI = 2.1-219.2; P = 0.022). CONCLUSION: Different types, frequencies, and intensities of physical activity were associated with reduced stroke incidence, implying that there is an option for everyone. Daily or every other day activities are more critical in reducing stroke than reducing sedentary behavior duration.

COVID-19 and arrhythmia: An overview.

Arrhythmias in COVID-19 patients are associated with hypoxia, myocardial ischemia, cytokines, inflammation, electrolyte abnormalities, pro-arrhythmic or QT-prolonging medications, and underlying heart conditions such as severe congestive heart failure, inherited arrhythmia syndromes, or congenital heart conditions. In the pediatric population, multisystem inflammatory syndrome can lead to cardiac injury and arrhythmias. In addition, arrhythmias and cardiac arrests are most prevalent in the critically ill intensive care unit COVID-19 patient population. This review presents an overview of the association between COVID-19 and arrhythmias by detailing possible pathophysiological mechanisms, existing knowledge of pro-arrhythmic factors, and results from studies in adult and pediatric COVID-19 populations, and the clinical implications.

The role of the electrocardiogram in the recognition of cardiac transplant rejection: A systematic review and meta-analysis.

BACKGROUND: In cardiac transplant recipients, the electrocardiogram (ECG) is a noninvasive measure of early allograft rejection. The ECG can predict an acute cellular rejection, thus shortening the time to recognition of rejection. Earlier diagnosis has the potential to reduce the number and severity of rejection episodes. METHODOLOGY: A systematic literature review was conducted to identify and select the original research reports on using electrocardiography in diagnosing cardiac transplant rejection in accordance with the PRISMA guidelines. Studies included reported sensitivity and specificity of ECG readings in heart transplant recipients during the first post-transplant year. Data were analyzed with Review manager version 5.4. p-value was used in testing the significant difference. RESULTS: After the removal of duplicates, 98 articles were eligible for screening. After the full-text screening, a total of 17 papers were included in the review based on the above criteria. A meta-analysis of five studies was done. CONCLUSION: In heart transplant recipients, a noninvasive measure of early allograft rejection has the potential to reduce the number and severity of rejection episodes by reducing the time and cost of surveillance of rejection and shortening the time to recognition of rejection.

Clinical and laboratory factors associated with coronavirus disease 2019 (Covid-19): A systematic review and meta-analysis.

SARS Coronavirus-2 is one of the most widespread viruses globally during the 21st century, whose severity and ability to cause severe pneumonia and death vary. We performed a comprehensive systematic review of all studies that met our standardised criteria and then extracted data on the age, symptoms, and different treatments of Covid-19 patients and the prognosis of this disease during follow-up. Cases in this study were divided according to severity and death status and meta-analysed separately using raw mean and single proportion methods. We included 171 complete studies including 62,909 confirmed cases of Covid-19, of which 148 studies were meta-analysed. Symptoms clearly emerged in an escalating manner from mild-moderate symptoms, pneumonia, severe-critical to the group of non-survivors. Hypertension (Pooled proportion (PP): 0.48 [95% Confident interval (CI): 0.35-0.61]), diabetes (PP: 0.23 [95% CI: 0.16-0.33]) and smoking (PP: 0.12 [95% CI: 0.03-0.38]) were highest regarding pre-infection comorbidities in the non-survivor group. While acute respiratory distress syndrome (PP: 0.49 [95% CI: 0.29-0.78]), (PP: 0.63 [95% CI: 0.34-0.97]) remained one of the most common complications in the severe and death group respectively. Bilateral ground-glass opacification (PP: 0.68 [95% CI: 0.59-0.75]) was the most visible radiological image. The mortality rates estimated (PP: 0.11 [95% CI: 0.06-0.19]), (PP: 0.03 [95% CI: 0.01-0.05]), and (PP: 0.01 [95% CI: 0-0.3]) in severe-critical, pneumonia and mild-moderate groups respectively. This study can serve as a high evidence guideline for different clinical presentations of Covid-19, graded from mild to severe, and for special forms like pneumonia and death groups.

Effects of sleep intervention on glucose control: A narrative review of clinical evidence.

BACKGROUND: Optimizing sleep has been recently gained exposure as a promising lifestyle consideration to aid in the control of diabetes. The evidence to support the impact of sleep quantity and quality on blood glucose control is largely acknowledged. This study aimed to review all published randomized controlled trials (RCTs) investigating the relationship between sleep and glucose control to synthesize an accurate overview. METHOD: Literature from PubMed and Google Scholar was searched using the listed search terms to obtain RCTs on the role of sleep in glucose homeostasis. Seven RCTs were eligible and included in our review. References in these RCTs were screened for the presentation of the pathophysiology of metabolic disturbances relating to the sleep duration, and the relevant factors affecting blood glucose concentration. RESULTS: Sleep deprivation and poor sleep quality are connected with blood glucose disturbance and reduction of insulin sensitivity. This leaves diabetic patients at an increased risk of glucose level fluctuations. However, the function of ß-cells was likely to be conserved after 14-days of sleep deprivation. Sleep extension from 7 to 14 days improved blood glucose control and insulin sensitivity in both healthy and diabetes participants. Diabetes sleep education and personalized interventions that reduced stress and improved sleep quality contributed to glucose homeostasis in diabetic patients. Overall improving one's sleep hygiene was found to improve glucose control in diabetic patients. CONCLUSION: Longer or short-term sleep deprivation may negatively affect glucose homeostasis, although the body temporarily compensates for the impaired function of ß-cells when reduced sleep lasted up to 14 days. Thus, we recommend optimum sleep duration and optimistic sleep duration and sleep quality for decreasing risk and progression of diabetes.

Mini-review on the properties and possible applications of therapeutic oxygen carrier Hemarina-M101.

Therapeutic Oxygen Carriers (TOCs) have been studied in the past for utilization in resuscitation fluid, treatment of organ ischemia, and as an alternative to red blood cell transfusion. One TOC, Hemarina-M101, seems promising in transplantation and oxygenation due its capability as a non-immunogenic, nontoxic, high-oxygen-carrying capacity TOC with little to no side effects. This mini-review focuses on Hemarina-M101 and explores its characteristics and possible utilities through past and recent studies.
