Adverse weather and poor visual cues are common elements in night-time Helicopter Emergency Medical Service (HEMS) operations contributing to spatial disorientation and fatal accidents. Pilots are required to make weather-related preflight risk assessments to accept or reject a flight. This study's aim was to develop p…

BACKGROUND: Femoroacetabular impingement as a result of slipped capital femoral epiphysis (SCFE) has been treated traditionally with a proximal femoral osteotomy, but open and arthroscopic femoral osteoplasty is becoming increasingly popular. Cam lesions result from excess bone primarily at the anterolateral femoral he…

BACKGROUND: This study's purpose was to determine the impact of THA implantation on pelvic motion, and to assess motion in patients with a history of lumbar fusion or prosthetic dislocation. METHODS: This was an IRB-approved, prospective investigation of 3 cohorts: (1) patients without a history of lumbar surgery unde…

OBJECTIVE: To measure the short-term effects of the Cancer-PEPSONE programme (CPP) on the partners' received and perceived social support, psychological distress, and quality of life (QOL), as well as explore the role of received social support as a mediator of the intervention effects. METHODS: Open single-center ran…

BACKGROUND: The optimal coronal alignment after total knee arthroplasty (TKA) has become an area of increased debate. Sources of variability among investigations include the radiographic technique used for both preoperative surgical planning and postoperative alignment assessments. This study's purpose was to assess th…

BACKGROUND: The early short-term outcomes and complications after revision of the recalled Rejuvenate modular neck hip arthroplasty have not been previously reported. This study's purpose is to describe the early outcomes and complications after revision of the Rejuvenate modular femoral neck. METHODS: A retrospective…

BACKGROUND: Adolescent low back pain (ALBP) can be considered a signal or precursor of a serious organic disease or telltale sign of future incidence of low back pain in adulthood. Published articles on ALBP in Nigeria are not readily available. OBJECTIVES: The study's objectives were to investigate the prevalence of…

INTRODUCTION: Noise-induced hearing loss is the most common cause of sensorineural hearing loss (SNHL) in military aviation. Few published studies compare SNHL rates between fixed and rotary-wing military pilots. The study's objective was to determine whether a difference in mean annual SNHL incidence rate exists betwe…

OBJECTIVE: In children with conduct problems, high levels of callous-unemotional traits are associated with amygdala hypoactivity to consciously perceived fear, while low levels of callous-unemotional traits may be associated with amygdala hyperactivity. Behavioral data suggest that fear processing deficits in children…

OBJECTIVES: The aim of this project was to evaluate the quality of life in patients undergoing treatment for head and neck cancer in the Murcia region (Spain). MATERIALS AND METHODS: The Quality of Life (QoL) of patients suffering head and neck cancer was assessed using Spanish translations of the European Organizatio…

Amphetamine-type substances are the second most widely used illicit drugs in the United States. There is evidence to suggest that stimulant use (cocaine and methamphetamine) has a heritable component, yet the areas of the genome underlying these use disorders are yet to be identified. This study's aims were to map loci…

Nasogastric tube (NGT) intubations occur frequently in clinical practice and can be a painful procedure for patients. A systematic review of current knowledge concerning the use of nebulized lidocaine to reduce the pain of NGT insertion was conducted in order to develop evidence-based guidelines. In addition, a meta-an…

BACKGROUND: Alzheimer's disease (AD) is the most common form of dementia worldwide. In Hispanic populations there are few validated tests for the accurate identification and diagnosis of AD. The Clinical Dementia Rating (CDR) scale is an internationally recognized questionnaire used to stage dementia. This study's obje…

UNLABELLED: THE STUDY'S RATIONALE: Patient participation is an essential factor in nursing care and medical treatment and a legal right in many countries. Despite this, patients have experienced insufficient participation, inattention and neglect regarding their problems and may respond with dependence, passivity or ta…

Although the implantable cardioverter defibrillator (ICD) has reduced the risk of sudden cardiac death, some recipients experience uncertainty and adjustment problems related to the device. The study's purpose was to test hypotheses that predicted defibrillator recipients with greater uncertainty would have less psycho…

The study's aim was to assess the association between adolescent girls' recall of child sexual abuse (CSA) and prevalence of dating victimization in early romantic relationships and to explore the link between multiple trauma history and mental disorders. When demographics and teacher-reported behavioral problems durin…

BACKGROUND: Concerns about adverse consequences of early childbearing and risk of sexually transmitted diseases (STD) have renewed interest in the sexual behaviour of adolescents in developing countries, where they represent a large proportion of the population and are at highest risk. To date, little is known about th…

Cicchetti and Lynch have conceptualized ecological contexts as consisting of nested levels with varying degrees of proximity to the individual. These levels of the environment interact and transact with each other over time in shaping individual development and adaptation. With a sample of maltreated (n = 188) and nonm…

Cyclic progestin therapy has been widely advocated as an adjunct to postmenopausal estrogen replacement therapy to reduce the risk of endometrial carcinoma. Acceptance of this approach, however, appears to have preceded detailed evaluation of possible adverse side effects of progestins that could result in patient nonc…

Sodium valproate enteric-coated tablets were administered as monotherapy to 118 patients (median age, 19 years) with primary generalized epilepsies. More than half (56%) of these patients were transferred from prior drug therapy, most of them because of inadequate seizure control, and some because of adverse effects. S…
