Background Endoscopic retrograde cholangiopancreatography (ERCP) is an invasive procedure. We aimed to investigate ERCP-induced perforations at our institution and conduct a comprehensive review of literature on ERCP-induced perforations (EIP) since the introduction of this procedure as a therapeutic intervention. Methods This was a case-control st...

This work combines the Urn allocation and O'Brien and Fleming multiple testing procedure to compare two treatments in clinical trials in a novel way. It is shown that this approach overcomes the constraints that previously made it challenging to apply the original adaptive design to clinical trials. The method provides unique flexibility, enabling...

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is an invasive procedure. We aimed to investigate ERCP-induced perforations at our institution and conduct a comprehensive review of literature on ERCP-induced perforations (EIP) since the introduction of this procedure as a therapeutic intervention. Methods: This was a case-control...

Background Objective monitoring of improvement during treatment of pulmonary exacerbation can be difficulty in children when pulmonary function testing cannot be obtained. Thus, the identification of predictive biomarkers to determine the efficacy of drug treatments is of high priority. The major aim of the current study was to investigate the seru...

In this study, we examined the relationship between social factors and language by focusing on color terms. We investigated patterns of color terms’ use and the diversity of the color terms lexicon (CTL) among males and females belonging to different subcultures—city vs. small town or urban vs. rural—and different university majors—professionally c...

This paper describes a new method for testing randomized clinical trials with binary outcomes, which combines the O’Brien and Fleming (1979) multiple-testing procedure with optimal allocations and unequal weighted samples simultaneously. The O’Brien and Fleming method of group sequential testing is a simple and effective method with the same Type I...

The way that COVID-19 has been handled since its inception in 2019 has had a significant impact on lifestyle-related behaviors, such as physical activities, diet, and sleep patterns. This study measures lifestyle-related behavior during the COVID-19 pandemic lockdown using a 22-item questionnaire. The responses were collected from March 2021 to Sep...

Background One of the most feared complications of endoscopic retrograde cholangiopancreatography (ERCP) is duodenal perforation. We aim to discuss the incidence and risk factors of ERCP induced perforation in light of pertinent literature and review therapeutic options of different perforation types. Methods In this case-control study, we reviewe...

Since its inception in 2019, COVID-19 has been associated with significant changes in lifestyle-related behavior, including physical activity, diet, and sleep, which are vital to maintaining our well-being. This study measures lifestyle-related behavior during the COVID-19 pandemic lockdown using a 21-item questionnaire. The responses were collecte...

Background: Induction of labour (IOL) is an important and common clinical procedure in obstetrics. In the current study, we evaluate predictors of vaginal delivery in both nulliparous and multiparous women in north Jordan who were induced with vaginal prostaglandins. Method: A prospective study was conducted on 530 pregnant women at King Abdulla...

Background: Frailty syndrome is characterized by a decline in physiological and psychological reserve and may be associated with poor health outcomes. Objectives: The current study explored frailty and its correlates among cognitively intact community-dwelling older adults. Methods: A secondary analysis of data collected from 109 community-dwe...

Children with epilepsy are at risk for impaired social cognition and autism. We aimed at evaluating the utility of the social responsiveness scale (SRS) for assessment of social impairment in these children. Prospective study; the SRS was applied to a group of children with epilepsy and a healthy control group. Intellectual disability in the epilep...

Background Implementing effective pain management is important to increase patient compliance in pediatric dental procedures. Aim This pilot study was conducted to evaluate the effectiveness of virtual reality (VR) on pain perception in dental procedures in children. Material and methods 54 children aged between 5-12 years were included. Patients...

Purpose: Childhood obesity and overweight are on the rise worldwide, and Jordanian children are no exception to this rule. Childhood Obesity has major implications on the physical and mental health of individuals, and it can often develop into adult obesity. Obesity/overweight correlates have not been researched extensively in the Middle East regio...

Background: Frailty syndrome is characterized by a decline in physiological and psychological reserve that leads to poor health outcomes. Objectives: The current study explored frailty and its impacts on health outcomes among older adults in close-knit Jordanian communities. Methods: A secondary analysis (N=109) of community-dwelling older adults a...

Scientists in biomedical and psychosocial research need to deal with skewed data all the time. In the case of comparing means from two groups, the log transformation is commonly used as a traditional technique to normalize skewed data before utilizing the two-group t-test. An alternative method that does not assume normality is the generalized line...

Objective The arteriovenous fistula is considered the preferred hemodialysis access due to its lower complication rate and longer patency. The aim of this study is to report the outcomes of arteriovenous fistula creation and to study the predictive factors for these outcomes. Study design and method This is a retrospective study of all patients wh...

Objective This study aimed to estimate the association of smoking with the direct medical expenditures for chronic disease management in north of Jordan. Design, setting and participants Retrospective cohort study using hospital database. Patients who were diagnosed with at least one chronic disease,were aged 18 years or older and had attended Kin...

Objective: Basal cell carcinoma (BCC) is the most common malignancy in humans and represents a growing public health care problem. The major etiological factors contributing to BCC development are exposure to ultraviolet radiation and genetic alterations. BCC is primarily caused by dysregulation of sonic Hedgehog (HH) signaling pathway in basal cel...

Speech production of children with cochlear implants (CIs) is generally characterized by low intelligibility and reduced phoneme accuracy. However, limited research investigated their speech production using acoustic measures. The current study examined voice onset time (VOT) for pharyngealized plosives [t,d], and spectral moments and noise duratio...

Abstract Background: The standard treatment of primary palmar hyperhidrosis had been thoracoscopic R2 sympathectomy, yet this sympathectomy level has been associated with serious unwanted side effects. Therefore, some recent experiences have recommended R2-sparing R3 or R4 thoracoscopic sympathectomy with less side effects, particularly compensato...

Introduction: Mineral trioxide aggregate (MTA) has been used in pulp capping of cariously exposed mature permanent teeth with promising results. The search for alternative materials that seal better and set faster than MTA and do not stain is ongoing. Biodentine (Septodont, St Maur-des-Fossés, France) exhibits these advantages but has not been tes...
