BACKGROUND: Missing outcome data can lead to bias in the results of systematic reviews. One way to address missing outcome data is by requesting the data from the trial authors, but non-response is common. One way to potentially improve response rates is by sending study participants advance communication. During the u…

BACKGROUND: The IMPaCT Back study (IMplementation to improve Patient Care through Targeted treatment for Back pain) is a quality improvement study which aims to investigate the effects of introducing and supporting a subgrouping for targeted treatment system for patients with low back pain (LBP) in primary care. This p…

BACKGROUND: Last menstrual period (LMP) and ultrasound are commonly used to estimate pregnancy length. Ovulation, which precedes fertilization by ≤24 hours, should give a more accurate estimate. METHODS: The Effects of Aspirin in Gestation and Reproduction (EAGeR) trial preconceptionally enrolled participants f…

STUDY DESIGN: Cross-sectional study. OBJECTIVES: This study's goal is to report whether Magnetization Transfer Ratio (MTR) can evaluate the severity of white matter (WM) injury in degenerative cervical myelopathy (DCM). SETTING: Laureate Institute of Brain Research, USA; Department of Neurosurgery, University of Okla…

BACKGROUND: The current study examined how psychological resilience acted as a buffer against mental health deterioration during the coronavirus disease 2019 (COVID-19) pandemic. We conducted an online survey in four countries (Japan, Malaysia, China, and the U.S.) to examine how psychological resilience functions towa…

The study's purpose was to examine age, gender, and education as potential moderators of the associations of perceived neighborhood environment variables with accelerometer-based moderate-to-vigorous physical activity (MVPA). Data were from 7273 adults from 16 sites (11 countries) that were part of a coordinated multi-…

PURPOSE: The purpose of this study was to assess the association between speech sound articulation and childhood stuttering in a relatively large sample of preschool-age children who do and do not stutter, using the Goldman-Fristoe Test of Articulation-2 (GFTA-2; Goldman & Fristoe, 2000). METHOD: Participants included…

OBJECTIVE: Bereavement-related depression is excluded from a diagnosis of major depressive episode (MDE) in DSM-IV, unless the syndrome is prolonged or complicated. The objective of this study is to assess the validity of the bereavement exclusion by comparing characteristics of bereavement-related episodes that are ex…

BACKGROUND: Epidemiological studies show wide variability in the occurrence of cannabis smoking and related disorders across countries. This study aims to estimate cross-national variation in cannabis users' experience of clinically significant cannabis-related problems in three countries of the Americas, with a focus…

OBJECTIVE: A genetic component in early childhood caries (ECC) is theorized, but no genome-wide investigations of ECC have been conducted. This pilot study is part of a long-term research program aimed to: (1) determine the proportion of ECC variance attributable to the human genome and (2) identify ECC-associated gene…

The most significant complication of parotid gland tumor surgery is facial weakness. This study compares the occurrence of transient facial palsy in patients with parotid gland tumors who underwent surgery without monitoring to those who underwent surgery with monitoring. The study's aim was to investigate facial nerve…

INTRODUCTION: Depression is a commonly overwhelming problem among patients with epilepsy which compromises their quality of life especially in developing countries. Previously limited studies were conducted using Becks Depression Inventory tool in Ethiopia. The aim of this study's objective was to determine the prevale…

BACKGROUND: Atrial fibrillation (AF) is the most common sustained arrhythmia affecting over 700,000 individuals in Japan and 2.2 million in the USA. The proper management of patients with AF is critical due to the well-documented association with heart failure and stroke. A strategy to better define the emergency depar…

BACKGROUND: Acute appendicitis is a common surgical emergency characterized by appendix inflammation. Surgery remains the gold standard for treatment with laparoscopy gaining in popularity. However, the optimal timing for appendectomy remains unclear. We are not aware of studies evaluating potential differences in clin…

BACKGROUND: Sleep problems during pregnancy may cause many complications that reduce quality of life. AIM: This study aims to determine the relationship between pregnant women's sleep characteristics and depressive symptoms. METHODS: A hospital-based, cross-sectional study was conducted. Pregnant women were selected…

BACKGROUND: The postpartum period can be a vulnerable time during which many women are prone to mood disturbances. Since telomere length (TL) is known to be associated with dysphoric moods, inflammation, and stress in many populations, this study's objective was to assess the relationships among TL, dysphoric moods, st…

BACKGROUND:: Patient-reported outcome measures (PROMs) are taking a more prominent role in orthopedics as health care seeks to define treatment outcomes. The visual analog scale (VAS) is considered a reliable measure of acute pain. A previous study found that operative candidates' VAS pain score was significantly highe…

BACKGROUND: The randomized controlled trial (RCT) is the gold standard study design allowing critical comparison of clinical outcomes while minimizing bias. Traditionally clinical trials are evaluated through statistical significance, expressed by P-values and confidence intervals. However, until recently, the robustne…

BACKGROUND: Prolotherapy (proliferative therapy) is a nonsurgical regenerative injection technique that introduces small amounts of hyperosmolar dextrose to the site of painful or degenerated tendons or their insertions. Under ultrasound guidance, a 25-gauge needle is used to fenestrate and inject hyperosmolar dextrose…

INTRODUCTION: The CyberKnife® (CK) system is capable of treating localised brain lesions with the help of a 6D skull tracking system. Hair position plays a crucial role in the success of CK radiosurgery for female brain lesion patients. This study aims to compare the intrafraction offset variation in two different…
