The relationship between statins and diabetic retinopathy: A review of literature

BackgroundTreatment with statins is a robust strategy in reducing cardiovascular complications among patients with diabetes mellitus and chronic kidney disease. There is an increasing awareness regarding the association of statins with diabetic retinopathy.AimsThe current review aimed to assess the relationship of statins therapy to diabetic retinopathy.Methods The literature in PubMed and Google Scholar was searched for relevant articles from the first available article up to present using the terms statins, simvastatin, atorvastatin, pravastatin, and diabetic retinopathy. Among the 169 articles retrieved, 26 full-texts were assessed for eligibility and only sixteen studies (four from the USA, another four from Europe, six from Asia, and one from Australia and Brazil each) met the inclusion criteria for the systematic review. The author name, year of publication, country, type of study, number of patients, and the duration of the study were reported.ResultsThe studies reviewed showed that statins reduce the development of diabetic retinopathy, retard the progression of hard exudates and micro-aneurisms, reduce retinopathy and macular oedema.ConclusionStatins prevent and reduce the progression of diabetic retinopathy and macular oedema

The relationship between periodontitis and diabetic retinopathy: A cross-sectional longitudinal study

BackgroundPeriodontal disease is regarded as the sixth complication of diabetes mellitus. The association of periodontitis with diabetic retinopathy is controversial.AimsThe study aimed to assess the association of periodontitis with diabetic retinopathy.Methods This is a cross-sectional descriptive study conducted at a diabetes centre in Omdurman, Sudan during the period from July to September 2018. One hundred and fifty-nine patients with type 2 diabetes were interviewed using a structured checklist. The demographic data and diabetes complications including retinopathy were recorded. An experienced dentist assessed the participants for periodontitis. The Statistical Package for Social Sciences (SPSS, version 20, New York) was used for data analysis. A P-value of > 0.05 was considered significant.Results Out of 159 patients with type 2 diabetes mellitus (65.4 per cent females), their age mean±SD was 58.13±9.96, periodontal diseases were found in 22.0 per cent of patients, and retinopathy was present in 34.6 per cent, while the number of lost teeth was 3.86±3.05. Between patients, periodontal disease (+) vs. (-), the incidence rate of the followings did not differ retinopathy, neuropathy, nephropathy, and coronary history. However, those with periodontal disease, compared with those without, had significantly more lost teeth P-value < 0.05.ConclusionThe number of lost teeth was higher among patients with diabetic retinopathy. However, a cause and effect cannot be withdrawn. Further larger multi-centre studies assessing the association of retinopathy with the severity of periodontal disease and controlling for other causes of teeth loss are needed

The relationship between diet soda soft drinks, artificial sweeteners, and diabetic retinopathy

BackgroundThe relationship between diabetic retinopathy and diet-drink (soft soda), non-nutritive sweeteners have not been fully determined. We here attempted to determine it.AimsThe study aimed to assess the association between soda soft drinks, non-nutritive sweeteners, and diabetic retinopathy.Methods A cross-sectional descriptive study was conducted at a diabetes center in Tabuk city, Saudi Arabia from September 2019 to April 2020: 174 patients with type 2 diabetes mellitus (DM) were interviewed using a structured questionnaire: demographic data, the DM duration, the lifestyles (exercise, smoking, and diet), and the medications. The weekly amount of diet soda and daily consumption of non-nutritive sweeteners were assessed. These were analysed with association with retinopathy.Results The glycated haemoglobin per cent was 8.50±1.60, the diet soda and artificial sweeteners consumptions were 1.18±1.57 cans/week and 0.89±1.26 sachets/day, respectively. No association was found between artificial sweeteners, diet soda, and diabetic retinopathy (Wald, 1.251, and 0.213, P-values, 0.263, and 0.644, 95 per cent CI, 0.583–7.204, and 0.190–2.793 respectively). Retinopathy incidence was associated with the DM duration (Wald, 8.095, P-value, 0.004, and 95 per cent CI, 0.766–0.952).ConclusionDiet soda and non-nutritive sweeteners were not associated with diabetic retinopathy, irrespective of gender or body mass index. Diabetic retinopathy was associated with the duration of DM after its first diagnosis

Impact of Knowledge and Attitude on Saudis’ Physical Activity Practice and Inactivity Barriers: A Questionnaire-based Study

BACKGROUND: Community participation in physical activity is considered a major public health preference of WHO. Saudi Arabia in the last decades faced many tremendous economic changes leading to adoption of western dietary habits associated with sedentary lifestyle. AIM: We aimed to study the relationship between both physical activity knowledge and attitude of community to the practice of individuals. METHODS: We used a questionnaire consists of a mixture of closed-ended questions. Participants were recruited through direct meetings in local markets, schools, and workplaces. Seven hundred and sixty six individuals agreed to participate. RESULTS: Overall correct answers to questions about importance of physical activity were 76.58%. The predominance of participants’ attitude was to establish public places for physical activity in each neighborhood (92.1%). Participants acknowledged that they exercise to improve their health (47.5%). Participants mainly perform light exercises (47.2%) on basis of 1–3 times weekly (48.9%). About 90.8% of participants admitted that they like to increase duration of their physical activity. CONCLUSIONS: Overall physical activity practice of participants’ needs encourage overcoming obstacles that prevent individuals from practicing especially lack of time

Squint Among Adult Population in Hail City, Saudi Arabia

Background: Strabismus, also known as crossed eyes, is a condition in which the eyes do not properly align with each other when looking at an object. If present during a large part of childhood, it may result in amblyopia. If onset is during adulthood, it is more likely to result in double vision. Objective: The aim of the study was to estimate the prevalence of squint, types and treatment characteristics in the studied adults in Hail city, Saudi Arabia. Methods: A cross-sectional study conducted in Hail city, Saudi Arabia. The study included 294 participants; 95 male and 199 female adults aged &gt;20 years. The study period was from 1 January to 30 April 2018. Data collected by personal interview using a pre-designed questionnaire, which distributed among the participants to be self-reported. Results: The prevalence of squint among the studied population was 9.9%. it was more common in females than males. Squint was right sided in 24.1% of the cases, left sided in 51.7% and in both eyes in 24.1% of the studied cases. About half (44.8%) of cases had inward squint (esotropia) and 10.3% outward squint (exsotropia), 24.1% of the cases had Intermittent squint and 6.9% had permanent squint. Most (55.2%) of squint cases use glasses and 34.5% of cases squint affected their visual acuity. In 6.9%, squint causes psychological troubles. As regards treatment, 20.7% received medical treatment and 17.2% received surgical treatment but 62.1% do not seek medical care. Only 10.3% of cases completely cured and 13.8% had recurrence. There was insignificant relation with age, sex, education, squint in parents, chronic diseases, consanguinity or hereditary diseases (P&gt;0.05). Conclusion: in this study, the prevalence of squint in the adult participants in Hail city, Saudi Arabia was 9.9% but 62.1% do not seek medical care. After treatment, only 10.3% of cases completely cured and 13.8% had recurrence. Health education of the public about importance of early treatment is highly recommended.

Comparison of total endoscopic thyroidectomy with conventional open thyroidectomy for treatment of papillary thyroid cancer

BackgroundRecent advance of endoscopic techniques has allowed surgeons to perform thyroidectomy via an incision placement at hidden places which lead to better cosmetic acceptability compared with conventional open thyroidectomy.AimsThis study was conducted to summarize the current evidence that compare open thyroidectomy with endoscopic ‎thyroidectomy in treatment of papillary thyroid cancer‎.‎Methods An electronic literature review, including PubMed, Google Scholar, and EBSCO that examining randomized trials of endoscopic thyroidectomy (ET), conventional open thyroidectomy (COT), and management of papillary thyroid carcinoma was carried out.Results The review included 8 randomized studies that compare total endoscopic thyroidectomy versus conventional open thyroidectomy in treatment of papillary thyroid cancer. The findings showed endoscopic thyroidectomy had statically significant cosmetic appearance, less amount of blood loss and occurrence of transient hypocalcaemia than conventional open thyroidectomy in form of cosmetic outcome, amount lower blood loss.ConclusionThe current review showed that, ET has a better cosmetic outcome and lower blood loss compared with COT. While COT was associated with significantly low operation time, hospital stay, drainage time, amount of drainage fluid and transient recurrent laryngeal nerve (RLN) palsy

Amblyopia and Routine Eye Exam in Children: Parent’s Perspective

Amblyopia is a reduced best-corrected visual acuity of one or both eyes that cannot be attributed to a structural abnormality; it is a functional reduction in the vision of an eye caused by disuse during a critical period of visual development. It is considered the leading cause of visual defects in children. With early diagnosis and treatment, children with amblyopia can significantly improve their vision. However, if it is neglected and not treated during childhood, unfortunately, it permanently decreases vision. Therefore, prevention, detection, and treatment largely depend on parents. This article explores parents’ perspectives on amblyopia and routine examination of their children’s eyes. A cross-sectional study used an electronic questionnaire consisting of five main sections to assess the level of awareness of amblyopia among parents. As a result, a total of 325 participants were included in our analysis. 209 (64.3%) were mothers, and 116 (35/7%) were fathers. The age groups were 35–50 years of age (61.5%), 20–34 years (23.4%), and older than 50 years (15%). Participants with a history of amblyopia numbered 23 (7.1%), and 39 had an amblyopic child (12%). A good awareness level of amblyopia among parents was found in only 10 (3%) participants, a fair awareness level in 202 (62%), and 113 (35%) participants were classified as having a poor awareness level of amblyopia. Only 13.8% of the parents took their children for yearly routine eye exams, while the majority (72%) took their children only if they had a complaint, and 14.2% took them for eye checkups only before school entry. In conclusion, parents’ awareness of amblyopia in Tabuk City, KSA, was low. In addition, a limited proportion of parents reported consistently taking their children for routine eye exams. Therefore, raising awareness should be considered in public education regarding the disease

Diabetic Retinopathy and Eye Screening: Diabetic Patients Standpoint, Their Practice, and Barriers; A Cross-Sectional Study

Diabetes mellites (DM) is one of the most common systemic disorders in Saudi Arabia and worldwide. Diabetic retinopathy (DR) is a potentially blinding ophthalmic consequence of uncontrolled DM. The early detection of DR leads to an earlier intervention, which might be sight-saving. Our aim in this cross-sectional study is to assess patients’ knowledge and practices regarding DR, and to detect the barriers for eye screening and receiving a check-up from an ophthalmologist. The study included 386 diabetic patients. One hundred and thirty-one patients (33.9%) had T1DM and 188 (48.7%) had T2DM. Most of the diabetic patients (73.3%) know that they must have an eye check-up regardless of their blood sugar level. DM was agreed to affect the retina in 80.3% of the patients, 56% of patients agree that DM complications are always symptomatic, and 84.5% know that DM could affect their eyes. The fact that blindness is a complication of diabetic retinopathy was known by 65% of the diabetic patients. A better knowledge was detected among patients older than 50 years of age (54.9%) compared to those aged less than 35 years (40.9%), which was statistically significant (p = 0.030). Additionally, 61.2% of diabetic patients who were university graduates had a significantly better knowledge in comparison to 33.3% of illiterate patients (p = 0.006). Considering the barriers to not getting one’s eyes screened earlier, a lack of knowledge was reported by 38.3% of the patients, followed by lack of access to eye care (24.4%). In conclusion, there is a remarkable increase in the awareness of DR among the Saudi population. This awareness might lead to an earlier detection and management of DR

Immunogenicity of High-Dose MVA-Based MERS Vaccine Candidate in Mice and Camels

The Middle East respiratory syndrome coronavirus (MERS-CoV) is a zoonotic pathogen that can transmit from dromedary camels to humans, causing severe pneumonia, with a 35% mortality rate. Vaccine candidates have been developed and tested in mice, camels, and humans. Previously, we developed a vaccine based on the modified vaccinia virus Ankara (MVA) viral vector, encoding a full-length spike protein of MERS-CoV, MVA-MERS. Here, we report the immunogenicity of high-dose MVA-MERS in prime–boost vaccinations in mice and camels. Methods: Three groups of mice were immunised with MVA wild-type (MVA-wt) and MVA-MERS (MVA-wt/MVA-MERS), MVA-MERS/MVA-wt, or MVA-MERS/MVA-MERS. Camels were immunised with two doses of PBS, MVA-wt, or MVA-MERS. Antibody (Ab) responses were evaluated using ELISA and MERS pseudovirus neutralisation assays. Results: Two high doses of MVA-MERS induced strong Ab responses in both mice and camels, including neutralising antibodies. Anti-MVA Ab responses did not affect the immune responses to the vaccine antigen (MERS-CoV spike). Conclusions: MVA-MERS vaccine, administered in a homologous prime–boost regimen, induced high levels of neutralising anti-MERS-CoV antibodies in mice and camels. This could be considered for further development and evaluation as a dromedary vaccine to reduce MERS-CoV transmission to humans

Role of Tele-Physical Therapy Training on Glycemic Control, Pulmonary Function, Physical Fitness, and Health-Related Quality of Life in Patients with Type 2 Diabetes Mellitus (T2DM) Following COVID-19 Infection—A Randomized Controlled Trial

The use of tele-rehabilitation (TR) in type 2 diabetes mellitus (T2DM) following COVID-19 infection remains unexplored. Hence, the purpose of this study was to determine the clinical effects of tele-physical therapy (TPT) on T2DM following COVID-19 infection. The eligible participants were randomized into two groups, a tele-physical therapy group (TPG; n = 68) and a control group (CG; n = 68). The TPG received tele-physical therapy for four sessions a week for eight weeks, and the CG received patient education for 10 min. The outcome measures were HbA1c levels, pulmonary function (forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC, maximum voluntary ventilation (MVV), and peak exploratory flow (PEF)), physical fitness, and quality of life (QOL). The difference between the groups in HbA1c levels at 8 weeks was 0.26 (CI 95% 0.02 to 0.49), which shows greater improvement in the tele-physical therapy group than the control group. Similar changes were noted between the two groups after 6 months and at 12 months resulting in 1.02 (CI 95% 0.86 to 1.17). The same effects were found in pulmonary function (FEV1, FVC, FEV1/FVC, MVV, and PEF), physical fitness, and QOL (p = 0.001). The reports of this study show that tele-physical therapy programs may result in improved glycemic control and improve the pulmonary function, physical fitness, and quality of life of T2DM patients following COVID-19 infection
