Impact of combined component separation technique and shoelace repair on big medline abdominal wall defect.

Background: Closure of large anterior abdominal wall defects, regardless of their etiology, is challenging. There is no standardized information describing definitive management. Therefore, we conducted this study to illustrate our experience on large midline abdominal wall defect repair using an effective modified reconstructive technique.

Steps and Challenges in Creating and Managing Quarantine Capacity During a Global Emergency - Qatar's Experience.

Background: COVID-19 pandemic has exposed the lack of adequate and appropriate quarantine capacity globally. Most countries lack the knowledge and/or capacity to set up and manage quarantine facilities at a national scale.

Methods: The State of Qatar developed a systematic plan to create and manage quarantine facilities for persons with confirmed or suspected COVID-19 infection or returning travelers and residents.

MicroRNA-1911-3p targets mEAK-7 to suppress mTOR signaling in human lung cancer cells.

Regulation of mTOR signaling depends on an intricate interplay of post-translational protein modification. Recently, mEAK-7 (mTOR associated protein, eak-7 homolog) was identified as a positive activator of mTOR signaling via an alternative mTOR complex. However, the upstream regulation of mEAK-7 in human cells is not known.

mEAK-7 Forms an Alternative mTOR Complex with DNA-PKcs in Human Cancer.

MTOR associated protein, eak-7 homolog (mEAK-7), activates mechanistic target of rapamycin (mTOR) signaling in human cells through an alternative mTOR complex to regulate S6K2 and 4E-BP1. However, the role of mEAK-7 in human cancer has not yet been identified. We demonstrate that mEAK-7 and mTOR signaling are strongly elevated in tumor and metastatic lymph nodes of patients with non-small-cell lung carcinoma compared with those of patients with normal lung or lymph tissue.

Ultra-Thin Platinum Deposits by Surface-Limited Redox Replacement of Tellurium.

Platinum is the most employed electrocatalyst for the reactions taking place in energy converters, such as the oxygen reduction reaction in proton exchange membrane fuel cells, despite being a very low abundant element in the earth's crust and thus extremely expensive. The search for more active electrocatalysts with ultra-low Pt loading is thus a very active field of investigation. Here, surface-limited redox replacement (SLRR) that utilizes the monolayer-limited nature of underpotential deposition (UPD) was used to prepare ultrathin deposits of Pt, using Te as sacrificial metal.

A screening tool for attention deficit hyperactivity disorder in children in Saudi Arabia.

Background And Objectives: A clinically validated attention deficit hyperactivity disorder (ADHD) scale in Arabic for evaluating children in Saudi Arabia who might be suspected of having ADHD is lacking. Thus, we studied the validity of an Arabic version of the ADHD Rating Scale in discriminating children with an ADHD diagnosis from normal children or from those with non-ADHD psychiatric diagnoses, including mental retardation.

Methods: The guardians of 119 children provided demographic data and completed the standardized Arabic version of the ADHD Rating Scale on their children, who were either normal, had a diagnosis of ADHD, or had a non-ADHD psychiatric diagnosis.

Assessment of pediatricians' need for training in child psychiatry.

Background: Psychosocial problems are common health concerns in children. Therefore, it is essential for pediatricians to be able to identify psychiatric disorders. This depends on the knowledge, practice and attitudes towards psychiatric disorders in childhood.

Munchausen syndrome by proxy and child's rights.

Munchausen syndrome by proxy (MSBP) is an extreme form of child abuse in which perpetrators induce life-threatening conditions in their children. A case of MSBP is described in detail. Difficulties in diagnosis and management in this part of the world are presented.

Parental attitudes toward the prescription of psychotropic medications for their children.

Objective: To explore parental attitudes towards the prescription of psychotropic medication for their children.

Method: A questionnaire built to collect socio-demographic data of parents and their attitudes was distributed among parents.

Results: One thousand and ten questionnaires were filled by parents.

Establishing a consultation-liaison psychiatry service. Impact on clinical indices.

Objective: To show prospectively the impact of establishing a consultation-liaison (C/L) psychiatry model on the consultation clinical indices.

Methods: A structured, organized model of C/L psychiatry was established in 1990 at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia and all clinical indices of the psychiatric consultations were compared prospectively over the first 3 years after January 1990 with those over the previous 2 years retrospectively before January 1990.

Results: Three hundred and two patients were referred over 3 years after January 1990, group A and 99 patients were referred over the 2 years before January 1990, group B and the male to female ratio were similar in both groups 1:1.

Survey of inpatients child and adolescent psychiatric referrals in a teaching hospital in Saudi Arabia.

Objective: To answer the question of which specialties utilize the service of child and adolescent liaison psychiatry and what are the problems that are likely to bring a child or an adolescent to the attention of psychiatry.

Methods: The case records of all inpatient children and adolescents younger than 18 years, who were referred to the psychiatric team at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia over a period of 6 years between July 1992 and July 1998, were retrospectively reviewed in regard to sociodemographic data, referring specialties and reason for referral.

Results: Seven percent of referred patients were younger than 18 years.
