External validation of a cardiovascular risk model for Omani patients with type 2 diabetes mellitus: a retrospective cohort study.

Objectives: To externally validate a recently developed cardiovascular disease (CVD) risk model for Omanis with type 2 diabetes mellitus (T2DM).

Design: Retrospective cohort study.

Setting: Nine primary care centres in Muscat Governorate, Oman.

Knowledge, attitudes, and practices toward research among Oman medical specialty board residents.

Objectives: The Accreditation Council for Graduate Medical Education has mandated residency programs to teach the basic principles of research in residency programs. This study aimed to assess the research knowledge, attitude, and practice among the Oman Medical Specialty Board (OMSB) residents. Secondarily, it aimed to asses associations between different factors and research-related knowledge, attitude, and practice.

The effect of low-carbohydrate ketogenic diet in the management of obesity compared with low caloric, low-fat diet.

Background & Aims: Previous studies comparing low-carbohydrate ketogenic diet (LCKD) and low caloric fat low diets (LCLF) in obesity management are still controversial. This study evaluated the effect of LCKD in weight reduction compared to the LCLF diet among Omani obese adults.

Methods: This prospective cohort study was conducted at the National Diabetes and Endocrine Centre (NDEC), Royal Hospital, Muscat, Oman, between 2015 and 2017.

Outcomes of Infants Undergoing Modified Blalock-Taussig Shunt Procedures in Oman: A retrospective study.

Objectives: A modified Blalock-Taussig (mBT) shunt procedure is a common palliative surgery used to treat infants and children with cyanotic congenital heart disease (CCHD). This study aimed to report the outcomes of infants and children undergoing mBT shunt procedures in Oman. In addition, risk factors associated with early mortality, inter-stage mortality and reintervention were assessed.

Cancer Risk Factors Among Omanis: A Review.

Background: Studying risk factors for cancer is the way for prevention and control. This study aims to review analytic studies reporting the identified risk factors of cancer in Oman.

Methods: A comprehensive literature search was conducted on "PubMed database, Scopus database, and Google Scholar", using appropriate key terms/words.

New approaches to disease causation research based on the sufficient-component cause model.

Up to date, the sufficient-component cause model seems to be a theoretical framework for disease causation in epidemiology, and its implications in epidemiological research methods is currently still limited. Recently, pitfalls in current epidemiological research methods were addressed based on the sufficient-component cause model; hence, new research approaches are needed as alternatives. Therefore, this paper aims to review and suggest new epidemiological methods used to assess disease causation.

Diabetic retinopathy among Omanis: Prevalence and clinical profile.

Purpose: The aim of this study is to describe the prevalence, severity and clinical profile of diabetic retinopathy (DR) among Omani diabetic patients attending a tertiary care hospital.

Materials And Methods: This is a retrospective study involving the record review of diabetic patients attending the diabetes retina clinic of the National Diabetes and Endocrine Centre in the period between June 2015 and May 2016. Retinal evaluation of 442 native patients was conducted using direct ophthalmological examination and digital photography.

Pediatric Diabetic Retinopathy: Experience of a Tertiary Hospital in Oman.

Purpose: The aim of this study is to describe the prevalence and clinical profile of pediatric diabetic retinopathy (DR) among Omani diabetic children and adolescents attending a tertiary care hospital.

Methods: This retrospective cross-sectional study involved the record review of 216 diabetic children attending the diabetes retina clinic of the National Diabetes and Endocrine Centre in the period between June 2015 and November 2018. The retinal evaluation was conducted using direct ophthalmological examination and fundus photography.

'MOVEdiabetes': a cluster randomized controlled trial to increase physical activity in adults with type 2 diabetes in primary health in Oman.

Objective: This study examined the impact of a multicomponent intervention to increase physical activity (PA) in adults with type 2 diabetes (T2D) in Oman.

Research Design And Methods: This is a cluster randomized controlled trial in eight primary health centers. Participants were physically inactive, aged ≥18 years, and with no contraindication to PA.

Validation of the cardiovascular risk model developed for Omanis with type 2 diabetes.

Aim: The first cardiovascular risk prediction model in the Arab world was recently developed for Omanis with type 2 diabetes mellitus. This study aims to validate the newly developed model.

Materials And Methods: A retrospective cohort study design was applied in this study.

Cardiovascular risk prediction model for Omanis with type 2 diabetes.

Aim: To date, no cardiovascular risk assessment tool has been developed specifically for any Arabian population including Omanis. This study aims to develop a suitable cardiovascular risk prediction model in the form of a statistical equation, for Omanis with type 2 diabetes.

Materials And Methods: A sample of 2039 patients with type 2 diabetes selected from primary care settings in the Aldakhiliyah Province of Oman were involved in a retrospective cohort study.
